Gastrointestinal ( GI ) symptoms and irritable bowel ( IB ) symptoms have been associated with chronic fatigue syndrome/myalgic encephalomyelitis ( CFS/ME ) . The aim of this study was to conduct a systematic review of these symptoms in CFS/ME , along with any evidence for probiotics as treatment . Pubmed , Scopus , Medline ( EBSCOHost ) and EMBASE data bases were search ed to source relevant studies for CFS/ME . The review included any studies examining GI symptoms , irritable bowel syndrome ( IBS ) and /or probiotic use . Studies were required to report criteria for CFS/ME and study design , intervention and outcome measures . Quality assessment was also completed to summarise the level of evidence available . A total of 3381 publications were returned using our search terms . Twenty-five studies were included in the review . R and omised control trials were the predominant study type ( n = 24 ) . Most of the studies identified examined the effect of  probiotic supplementation on the improvement of IB symptoms in IBS patients , or IB symptoms in CFS/ME patients , as well as some other significant secondary outcomes ( e.g. quality of life , other gastrointestinal symptoms , psychological symptoms ) . The level of evidence identified for the use of  probiotics  in IBS was excellent in quality ; however , the evidence available for the use of probiotic interventions in CFS/ME was poor and limited . There is currently insufficient evidence for the use of probiotics in CFS/ME patients , despite probiotic interventions being useful in IBS . The studies pertaining to probiotic interventions in CFS/ME patients were limited and of poor quality overall . St and ardisation of protocol s and methodology in these studies is required Aim Previous systematic review s have found hydrotherapy to be an effective management strategy for  fibromyalgia syndrome ( FMS ) .  The aim of this systematic review was to summarize the components of hydrotherapy programs used in r and omized controlled trials . Method A systematic review of r and omized controlled trials was conducted . Only trials that have reported significant FMS-related outcomes were included . Data relating to the components of hydrotherapy programs ( exercise type , duration , frequency and intensity , environmental factors , and service delivery ) were analyzed . Results Eleven r and omized controlled trials were included in this review . Overall , the quality of trials was good . Aerobic exercise featured in all 11 trials and the majority of hydrotherapy programs included either a strengthening or flexibility component . Great variability was noted in both the environmental components of hydrotherapy programs and service delivery . Conclusions Aerobic exercise , warm up and cool-down periods and relaxation exercises are common features of hydrotherapy programs that report significant FMS-related outcomes . Treatment duration of 60 minutes , frequency of three sessions per week and an intensity equivalent to 60%–80 % maximum heart rate were the most commonly reported exercise components . Exercise appears to be the most important component of an effective hydrotherapy program for FMS , particularly when considering mental health-related outcomes Background : Type 2 diabetes mellitus ( T2DM ) is becoming a leading problem worldwide . Emerging reports reveal alarming evidence of increasing prevalence of T2DM that has reached p and emic levels . Despite the significant incidence , there are limited reliable data re sources and comprehensive systematic review and meta- analysis on the effects of yoga on people who are a prediabetic or high risk for developing T2DM . Objective : The objective of this protocol is to conduct a full-scale systematic review and meta-analyses on the effects of yoga on people who are prediabetes or high risk of developing T2DM . Methods : The articles enrolled in the study will be retrieved from the online data bases between 2002 and the date the search es are executed . The search es will be repeated just before the final analyses and further relevant studies for inclusion . We will conduct a bibliographic search in data bases : Medline / PubMed , Scopus , Cochrane Library , EBSCO , and IndMED using keywords including prediabetes state , high risk for diabetes , metabolic syndrome , and yoga . A defined search strategy will be implemented along with selection criteria to obtain full-text articles of relevant studies . This study protocol was prepared according to the Preferred Reporting Items for Systematic Review s and Meta- Analysis for Protocol s 2015 guidelines . There will be no language restrictions . Ethics and dissemination : The proposed study will be based on published studies and publicly available anonymized data without directly involving human participants and therefore requires neither formal human ethical review nor approval by a human research ethics committee . We published an outline of the protocol in the International Prospect i ve Register of Systematic Review s ( PROSPERO ) in 2018 . We plan to disseminate the findings of this systematic review and meta- analysis through publication in a peer- review ed journal and presentation at relevant conference proceedings . In addition , we believe the results of the systematic review will have implication s for policy and practice . We will prepare policymaker summary using a vali date d format , disseminate through social media and email discussion groups . Review registration number : PROSPERO registration number CRD AIMS To analyse the effect on systematic review s in diabetes interventions of including only trials that are indexed in medline , and to assess the impact of adding trials from other data bases and the grey literature . METHODS All systematic review s of diabetes interventions which included a meta- analysis of r and omized controlled trials , and were published since 1996 , were selected . The impact on the meta- analysis of including only those trials indexed in medline , and the effect of then adding trials from other sources , was assessed . Where possible this was measured quantitatively , by redoing the meta- analysis , otherwise a qualitative estimate was made . RESULTS Forty-four systematic review s met our inclusion criteria . There were 120 articles reporting trial data which were not indexed in medline . These came from 52 % of the review s. In 34 % of the review s , basing a meta- analysis on a search of only medline would miss trials that could affect the result . Sources of non- medline data which had the biggest effect on the meta-analyses were journal articles from central and embase ( mainly in Diabetes , Nutrition and Metabolism ) and unpublished data ( mainly from industry ) . The exceptions were journal articles on herbal medicine , mostly indexed in Chinese language data bases . CONCLUSIONS A search of only the medline data base is insufficient for systematic review s of diabetes , because in about 34 % of review s the missed trials could affect the results of the meta- analysis . It is recommended that central ( on the Cochrane Library ) also be search ed . Scanning meeting abstract s , and seeking unpublished data are also recommended if the intervention has only recently been introduced Background Gut microbiota is now known to control glucose metabolism . Previous studies have shown that probiotics and prebiotics may improve glucose metabolism , but their effects have not been studied in combination with drug therapy . The aim of this study was to investigate whether probiotics and prebiotics combined with drug therapy affect diabetic outcomes . Methods Two different study design s were used to test gut microbiota modulating treatments with metformin ( MET ) or sitagliptin ( SITA ) in male C57Bl/6J mice . In Design 1 , diabetes was induced with four-week feeding with a ketogenic , 72 kcal% fat diet with virtually no carbohydrates . Mice were then r and omly divided into four groups ( n = 10 in each group ) : ( 1 ) vehicle , ( 2 ) Bifidobacterium animalis ssp . lactis 420 ( B420 ) ( 109 CFU/day ) , ( 3 ) MET ( 2 mg/mL in drinking water ) , or ( 4 ) MET + B420 ( same doses as in the MET and B420 groups ) . After another 4 weeks , glucose metabolism was assessed with a glucose tolerance test . Fasting glucose , fasting insulin and HOMA-IR were also assessed . In Design 2 , mice were fed the same 72 kcal% fat diet to induce diabetes , but they were simultaneously treated within their respective groups ( n = 8 in each group ) : ( 1 ) non-diabetic healthy control , ( 2 ) vehicle , ( 3 ) SITA [ 3 mg/(kg*day ) ] ( 4 ) SITA with prebiotic polydextrose ( PDX ) ( 0.25 g/day ) , ( 5 ) SITA with B420 ( 109 CFU/day ) , and ( 6 ) SITA + PDX + B420 . Glucose metabolism was assessed at 4 weeks , and weight development was monitored for 6 weeks . Results In Design 1 , with low-dose metformin , mice treated with B420 had a significantly lower glycemic response ( area under the curve ) ( factorial experiment , P = 0.002 ) and plasma glucose concentration ( P = 0.02 ) compared to mice not treated with B420 . In Design 2 , SITA + PDX  reduced glycaemia in the oral glucose tolerance test significantly more than SITA only ( area under the curve reduced 28 % , P < 0.0001 ) . In addition , B420 , PDX or B420+PDX , together with SITA , further decreased fasting glucose concentrations compared to SITA only ( −19.5 , −40 and −49 % , respectively , P < 0.01 for each comparison ) . The effect of PDX may be due to its ability to increase portal vein GLP-1 concentrations together with SITA ( P = 0.0001 compared to vehicle ) whereas SITA alone had no statistically significant effect compared to vehicle ( P = 0.14 ) . Conclusions This study proposes that combining probiotics and /or prebiotics with antidiabetic drugs  improves glycemic control and insulin sensitivity in mice . Mechanisms could be related to incretin secretion BACKGROUND : Eczema is the most common inflammatory skin disease of childhood , characterized by an itchy red rash that usually involves the face and skin folds . There is currently no curative treatment for eczema , so the reduction of eczema incidence through disease prevention is a desirable goal . Potential interventions for preventing eczema include exclusive breastfeeding , hydrolysed protein formulas and soy formulas when bottle feeding , maternal antigen avoidance , omega oil supplementation , prebiotics and probiotics . OBJECTIVES : This overview of review s aims to present the current body of data from Cochrane and non-Cochrane review s to provide the most up-to- date evidence on the efficacy and safety of interventions to prevent eczema in infants and children at different risk levels for developing allergic disease . METHODS : Our pool of Cochrane and non-Cochrane review s came from the 2010 United Kingdom National Health Service ( NHS ) Evidence Skin Disorders Annual Evidence Up date s Mapping Exercise on Atopic Eczema . This group used a comprehensive search strategy last conducted in August 2010 to identify all systematic review s on eczema prevention . We identified all review s that met our pre-specified inclusion criteria , and data were extracted , analysed , compiled into tables and synthesized using quantitative and qualitative methods . MAIN RESULTS : Seven systematic review s containing 39 relevant trials with 11 897 participants were included in this overview . Overall , there was no clear evidence that any of the main interventions review ed reduced eczema incidence . In subgroup analyses of infants at high risk of allergic disease , an observational study found that exclusive breastfeeding for at least six months compared with introduction of solids at three to six months decreased the incidence of eczema by 60 % ( risk ratio ( RR ) : 0.40 ; 95 % confidence interval ( CI ) : 0.21 , 0.78 ) , and a r and omized controlled trial found that prebiotics compared with no prebiotics  decreased incidence by 58 % ( RR : 0.42 ; 95 % CI : 0.21 , 0.84 ) . However , each of these findings was based on the results of a single small trial , and no intervention reduced eczema incidence beyond the first two years of life . Although we pre-specified incidence of atopic eczema ( i.e. eczema associated with immunoglobulin E ( IgE ) sensitization ) as a primary outcome , data on whether participants diagnosed with eczema were truly atopic were largely lacking from systematic review s. Similarly , data on atopy , measured using skin prick tests or specific IgE tests to allergens , were not reported in many review s. No interventions were found to decrease atopy when reported . Adverse events data were generally lacking , but data from a trial of probiotics versus no probiotics showed significantly more spitting up in the first one ( RR : 1.88 ; 95 % CI : 1.03 , 3.45 ) and two ( RR : 1.69 ; 95 % CI : 1.02 , 2.80 ) months of life , but no overall increase in risk of gastrointestinal symptoms in the first year . AUTHORS # ENTITYSTARTX02019 ; CONCLUSIONS : Although there is currently no clear evidence showing that any of the interventions examined in this overview prevent eczema in participants not selected for risk of allergic disease , there is some evidence that exclusive breastfeeding for at least six months and prebiotics might reduce eczema incidence in high-risk participants . However , these conclusions are based on limited evidence with method ological shortcomings . Future research on prevention of eczema is needed and should examine different types of hydrolysed formulas , prebiotics and probiotics , as well as enhancement of the skin barrier and other novel approaches in infants at different risk levels for developing allergic disease Background : Diabetes mellitus ( DM ) and vitamin D deficiency are major health concerns around the world . Evidence suggests a possible role of vitamin D in improvement of insulin secretion and sensitivity . Objectives : We assessed whether vitamin D supplementation could be used in vitamin D deficient-type II diabetes to improve glucose metabolism , components of metabolic syndrome ( MetS ) and specific inflammatory biomarkers . Patients and Methods : A double blind , r and omized clinical trial was conducted in King Khalid University Hospital , Saudi Arabia to evaluate the effect of cholecalciferol supplementation on glycemic control , MetS components and specific inflammatory biomarkers including tumor necrosis factor-alpha ( TNF-α ) , Interleukin ( IL-6 ) , leptin , adiponectin and vascular cell adhesion molecule-1 ( VCAM-1 ) . Twenty-two patients with type II diabetes with insulin resistance , glycated hemoglobin ( HbA1c ) ≥ 6 ( 42 mmol/mol ) and serum 25(OH)D < 50 nmol/L were r and omized using a computer program to receive either supplementation with cholecalciferol ( 5000 IU/day ) or placebo for 12 weeks . The primary outcome was change in HbA1c levels from baseline . Results : Median [ IQR ] 25(OH)D levels increased significantly in the vitamin D group as 58.1 [ 48 , 67.3 ] nmol/L ( P = 0.002 ) . There was no significant difference in the change of HbA1c between the groups ( P = 0.5 ) with a decrease of -0.1 % [ -1 , 0.5 ] in the vitamin D group and an increase of 0.15 % [ 0.1 , 0.2 ] in the placebo group . A significant improvement was observed in the homeostasis model of assessment of β-cell activity ( HOMA-%B ) ( P = 0.03 ) with vitamin D supplementation compared to baseline . Conclusions : Vitamin D repletion for 12 weeks increased serum vitamin D concentrations and improved β-cell activity in vitamin D-deficient type II diabetes with no significant changes in HbA1c or insulin sensitivity BACKGROUND Irritable bowel syndrome ( IBS ) is a chronic debilitating functional gastrointestinal disorder . Diet and lifestyle changes are important management strategies . The aim of these guidelines is to systematic ally review key aspects of the dietary management of IBS , with the aim of providing evidence -based guidelines for use by registered dietitians . METHODS Questions relating to diet and IBS symptom management were developed by a guideline development group . These included the role of milk and lactose , nonstarch polysaccharides ( NSP ) , fermentable carbohydrates in abdominal bloating , probiotics and empirical or elimination diets . A comprehensive literature search was conducted and relevant studies from January 1985 to November 2009 were identified using the electronic data base search engines : Cinahl , Cochrane Library , Embase , Medline , Scopus and Web of Science . Evidence statements , recommendations , good practice points and research recommendations were developed . RESULTS Thirty studies were critically appraised . A dietetic care pathway was produced following a logical sequence of treatment and formed the basis of these guidelines . Three lines of dietary management were identified . first line :  Clinical and dietary assessment , healthy eating and lifestyle management  with some general advice on lactose and NSP . Second line : Advanced dietary interventions to improve symptoms based on NSP , fermentable carbohydrates and probiotics . Third line : Elimination and empirical diets . Research recommendations were also identified relating to the need for adequately powered and well design ed r and omised controlled trials . CONCLUSIONS These guidelines provide evidence -based details of how to achieve the successful dietary management of IBS Background / Aims Despite numerous r and omized clinical trials and meta-analyses , there is no increased evidence for the efficacy of  probiotics  in the treatment of irritable bowel syndrome ( IBS ) . We review this evidence , identify and analyse the reasons for this lack of evidence and propose method ological improvements for future studies . Methods Based on a literature search , we identified 56 papers that matched the purpose of our analyses . Twenty-seven studies used multi-species bacterial preparations and 29 used single-strain probiotics . They were analysed regarding  patients included , treatment duration , probiotic dosage , and outcome measures . Results Trials in both groups suffered from heterogeneity with respect to probiotic concentration , duration of treatment , and other method ological issues ( crossover design and underpowered studies ) . This heterogeneity did not allow the application of a meta-analytic approach and a systematic review was therefore performed instead . Multi-strain preparations combined 2 to 8 different bacterial subspecies , mostly lactobacilli or bifidobacteria , and used variable lengths of treatments . Overall , more than 50 % of trials presented negative outcomes . The majority of the single-strain probiotic trials employing lactobacilli or Saccharomyces were negative , whereas trials employing bifidobacteria showed positive results . Conclusions The heterogeneity of the studies of probiotics in IBS questions the value of meta-analyses . The use of different bacterial strains and different mixtures of these strains , as well as different dosages , are the main contributors to this heterogeneity . Current data provides limited evidence for the efficacy of a small number of  single-strain probiotics  in IBS ( mostly bifidobacteria ) and sound studies following strict trial guidelines ( Food and Drug Administration and European Medicines Agency guidelines for clinical trials ) are needed . We summarised and proposed some method ological issues for future studies in the field OBJECTIVE Major depressive disorder ( MDD ) is associated with decreased physical activity and increased rates of the metabolic syndrome ( MetS ) , a risk factor for the development of type 2 diabetes and cardiovascular disorders . Exercise training has been shown to improve cardiorespiratory fitness and metabolic syndrome factors . Therefore , our study aim ed at examining whether patients receiving an exercise program as an adjunct to inpatient treatment will benefit in terms of physiological and psychological factors . METHOD Fourty-two in patients with moderate to severe depression were included . Twenty-two patients were r and omized to additional 3x weekly exercise training ( EXERCISE ) and compared to treatment as usual ( TAU ) . Exercise capacity was assessed as peak oxygen uptake ( VO2peak ) , ventilatory anaerobic threshold ( VAT ) and workload expressed as Watts ( W ) . Metabolic syndrome was defined according to NCEP ATPIII panel criteria . RESULTS After 6 weeks of treatment , cardiorespiratory fitness ( VO2peak , VAT , Watt ) , waist circumference and HDL cholesterol were significantly improved in EXERCISE participants . Treatment response expressed as ≥50 % MADRS reduction was more frequent in the EXERCISE group . CONCLUSIONS Adjunctive exercise training in depressed in patients  improves physical fitness , MetS factors , and psychological outcome . Given the association of depression with cardiometablic disorders , exercise training is recommended as an adjunct to st and ard antidepressant treatment Introduction While a number of strategies are being implemented to control cardiovascular diseases ( CVDs ) and type 2 diabetes mellitus ( T2DM ) , the cost-effectiveness of these in the South Asian context has not been systematic ally evaluated . We aim to systematic ally review the economic ( cost-effectiveness ) evidence available on the individual- , group- and population -level interventions for control of CVD and T2DM in South Asia . Methods and analysis This review will consider all relevant economic evaluations , either conducted alongside r and omised controlled trials or based on decision modelling estimates . These studies must include participants at risk of developing CVD/T2DM or with established disease in one or more of the South Asian countries ( India , Bangladesh , Pakistan , Sri Lanka , Nepal , Maldives , Bhutan and Afghanistan ) . We will identify relevant papers by systematic ally search ing all major data bases and registries . Selected articles will be screened by two independent research ers . Method ological quality of the studies will be assessed using a modified Drummond and a Phillips checklist . Cochrane guidelines will be followed for bias assessment in the effectiveness studies . Results Results will be presented in line with the PRISMA ( Preferred Reporting Items for Systematic review and Meta- analysis ) checklist , and overall quality of evidence will be presented as per the GRADE ( Grade s of Recommendation , Assessment , Development and Evaluation ) approach . Ethics and dissemination The study has received ethics approval from the All India Institute of Medical Sciences , New Delhi , India . The results of this review will provide policy-relevant recommendations for the uptake of cost-effectiveness evidence in prioritising decisions on essential chronic disease care packages for South Asia . Study registration number PROSPERO CRD42013006479 Aims /hypothesis Prospect i ve data directly investigating the role of endogenous sex hormones in diabetes risk have been scant , particularly in women . We aim ed to examine comprehensively plasma sex hormones in connection with risk of developing type 2 diabetes  in postmenopausal women . Methods We conducted a prospect i ve , nested case – control study of  plasma oestradiol , testosterone and dehydroepi and rosterone sulfate  and risk of type 2 diabetes in a cohort of women health professionals with a mean age of 60.3 and 12.2 years since menopause . Among women not using hormone therapy and free of baseline cardiovascular disease , cancer and diabetes , 359 incident cases of type 2 diabetes were matched with 359 controls during an average follow-up of 10 years . Results Oestradiol and testosterone were each strongly and positively associated with risk of type 2 diabetes . After adjustment for BMI , family history , lifestyle and reproductive variables , the multivariable relative risks ( 95 % CI ) comparing the highest vs lowest quintile were 12.6 ( 2.83–56.3 ) for total oestradiol ( p = 0.002 for trend ) , 13.1 ( 4.18–40.8 ) for free oestradiol ( p < 0.001 for trend ) , 4.15 ( 1.21–14.2 ) for total testosterone ( p = 0.019 for trend ) and 14.8 ( 4.44–49.2 ) for free testosterone ( p < 0.001 for trend ) . These associations remained robust after adjusting and accounting for other metabolic syndrome components and baseline HbA1c levels . Conclusions /interpretationIn postmenopausal women , higher plasma levels of oestradiol and testosterone were strongly and prospect ively related to increased risk of developing type 2 diabetes . These prospect i ve data indicate that endogenous levels of sex hormones may play important roles in the pathogenesis of type 2 diabetes . Clinical Trials.gov ID no. : NCT00000479 Objective To compare the safety and efficacy of the dipeptidylpeptidase-4 ( DPP-4 ) inhibitors in patients with type 2 diabetes and inadequate glycemic control . Design Systematic review of r and omized controlled trials ( RCTs ) , health economic evaluation studies , systematic review s , and meta-analyses , followed by primary Bayesian mixed treatment comparison meta-analyses ( MTCs ) , and secondary frequentist direct-comparison meta-analyses using a r and om-effects model . Outcomes were reported as weighted mean change from baseline , or odds ratio ( OR ) with 95 % credible interval . Data sources MEDLINE , MEDLINE In-Process , EMBASE , and BIOSIS via Dialog ProQuest ; Cochrane Central Register of Controlled Trials and Cochrane Data base of Systematic Review s via EBSCO ; four diabetes and two technical congress abstract s ; and health technology assessment organization websites . Eligibility criteria Patients with type 2 diabetes and inadequate glycemic control receiving any pharmacological anti-diabetic treatment . Data extraction and analysis Title/ abstract s were review ed for eligibility , followed by full-text review of publications remaining after first pass . A three-person team filtered articles and an independent review er checked a r and om selection ( 10 % ) of filtered articles . Data extraction and quality assessment of studies were also independently review ed . Five DPP-4 inhibitors ( alogliptin , linagliptin , saxagliptin , sitagliptin , and vildagliptin ) were compared via meta- analysis ( where data were available ) as monotherapy , dual therapy ( plus metformin , sulfonylurea , pioglitazone , or insulin ) , and triple therapy ( plus metformin/sulfonylurea ) . Results The review identified 6,601 articles ; 163 met inclusion criteria and 85 publications from 83 RCTs contained sufficient or appropriate data for analysis . MTCs demonstrated no differences between DPP-4 inhibitors in mean change from baseline in glycosylated hemoglobin ( HbA1c ) or body weight , or the proportions of patients achieving HbA1c < 7 % or experiencing a hypoglycemic event , apart from in patients on alogliptin plus metformin , who achieved HbA1c < 7 % more frequently than those treated with saxagliptin plus metformin [ OR 6.41 ( 95 % CI 3.15–11.98 ) versus 2.17 ( 95 % CI 1.56–2.95 ) ] . Conclusions This systematic review and MTC showed similar efficacy and safety for DPP-4 inhibitors as treatment for type 2 diabetes , either as monotherapy or combination therapy Review question / objective What are the effects of weight management interventions that include a diet component on weight‐related outcomes in pregnant and postpartum women ? The primary objective of this systematic review is to evaluate the effectiveness of weight management interventions which include a diet component and are aim ed at limiting gestational weight gain and postpartum weight retention in women . The second objective of this systematic review is to investigate included intervention components with respect to effect on weight‐related outcomes . This may include , but is not limited to : length of intervention , use of face‐to‐face counselling , group or individual consultations , use of other interventions components including exercise , use of goals and use of support tools like food diaries , coaching , including email or text message support . Background Around half of all women of reproductive age are either overweight or obese,1,2,3 with women aged 25‐34 years having a greater risk of substantial weight gain compared with men of all ages.1,4 Excessive gestational weight gain ( GWG ) and postpartum weight retention ( PPWR ) may play a significant role in long term obesity . Having one child doubles the five‐ and 10‐year obesity incidence for women , with many women who gain excessive weight during pregnancy remaining obese permanently.5 Excessive GWG and /or PPWR can also significantly contribute to short‐ and long‐term adverse health outcomes for mother , baby and future pregnancies.6,7 Maternal obesity increases the risk of pregnancy related complications such as pre‐eclampsia , gestational diabetes mellitus , stillbirth and the rate of caesarean section.8 Childhood obesity is a further long term complication of maternal obesity for offspring , which may persist in to adulthood.9 Excess GWG is also a risk factor for PPWR both in the short and long‐term.10,11 Nehring et al. conducted a meta‐ analysis with over 65,000 women showing that , compared to women who gained weight within recommendations during pregnancy , women with GWG above Institute of Medicine weight gain recommendations , 12 retained an additional 3.1 kg and 4.7 kg after three and greater than or equal to 15 years postpartum , respectively.13 The health risk associated with PPWR is highlighted in a study of 151,025 Swedish women followed between 1992 and 2001.The study identified the risk of adverse pregnancy outcomes for those who gained three or more units of Body Mass Index ( kg/m2 ) between consecutive pregnancies ( an average of two years ) was much higher compared with women whose BMI changed from ‐1.0 and 0.9 units.14 Long‐term chronic disease risk may also be affected by PPWR as weight retention at the end of the first year post‐partum has been found to be a predictor of maternal overweight 15 years later.15With around 14‐20 % of women retaining 5 kg or more 12 months postpartum,16,5 the risk of developing conditions like diabetes , metabolic syndrome and cardiovascular disease may be increased.17 It becomes evident that interventions which aim to support attainment of healthy weight both in the antenatal and postpartum periods are key health priorities for women during this life stage . Lifestyle factors of overweight , having poor diet quality , and not undertaking enough moderate‐to‐vigorous physical activity are amongst the top five predictors of mortality in women.18 Additionally it is noted that , for many women , pregnancy and the postpartum period are associated with a reduction in physical activity.19 It is known that a combination of poor dietary choices , an increase in sedentary time and reduction in physical activity are all contributors to the development of overweight and obesity . With this in mind , current research has focused on lifestyle interventions to limit GWG and PPWR . Thangaratinam et al. review ed 44 r and omized controlled trials ( 7278 women ) where interventions including diet , physical activity or both were evaluated for their influence on maternal weight during  pregnancy.20 Results indicate that all were significantly effective in reducing GWG compared with the control group . More specifically , dietary interventions were the most effective in reducing weight gain , with a mean weight loss of ‐3.84 kg compared with ‐0.72 kg and ‐1.06 kg for physical activity and the mixed ( diet plus physical activity ) approach , respectively.20 This finding is supported by Hill and colleagues ' recent systematic review of theory based interventions to limit GWG.21 Included studies in this review reported an underpinning theory base and were classified as adopting a dietary , physical activity or mixed approach . Hill et al. concluded that studies which included a diet intervention were significantly more effective at limiting GWG.21 In 2011 Tanentsapf et al. review ed the effect of dietary interventions alone for reducing GWG in normal weight , overweight and obese pregnant women.22 This review analysed 13 r and omized controlled trials and quasi‐r and omized controlled trials with a dietary intervention to prevent excessive GWG in women . The review concluded that dietary interventions during pregnancy were effective in reducing GWG with an effect of ‐1.92 kg ( n=1434 ) compared with the control group.22 Tanentsapf et al. identified that trials differed in the conduct of the interventions with various diet and non‐diet related components utilised . Dietary approaches were highly variable with some trials focusing only on calorie restriction and others included additional target macronutrient distribution for intake . Some trials further provided feedback based on maternal weight gain guidelines .12 Interventions also varied in delivery method with a variety of modes used , including face‐to‐face , individual or group consultations and /or written correspondence . The frequency of communication , despite the type or mix , also changed from trial to trial with additional methods via telephone , posted material s , feedback or food diaries utilised . The inclusion of physical activity in addition to diet intervention was also common . Whilst the recent review by Tanentsapf et al.22 identified that dietary interventions are effective in reducing GWG , the review did not investigate the impact that different intervention components , delivery methods or dietary counselling approaches had on gestational weight management . It remains unclear as to which intervention components optimize GWG in women . The impact of lifestyle interventions has also been investigated in the postpartum period . The recent systematic review from van der Pligt et al. reported seven of 11 studies review ed were successful in limiting PPWR.23 As with studies aim ed at limiting GWG , interventions included in van der Pligt et al. 's review differed greatly in their conduct . Six of these seven studies included both dietary and physical activity components for the intervention , with the final successful study including a diet only intervention . Five of the successful studies recruited overweight or obese women only . Intervention time varied considerably in successful studies with some running for as little at ten days , and others up to six months . Bertz et al. demonstrated that their 12‐week behavior modification intervention which targeted diet alone or diet and exercise , including two individual sessions with a dietitian and physical therapist , provision of scales for weight self‐monitoring and bi‐weekly text messages was successful in achieving significant weight loss following the intervention , and sustained at one year.24 The diet intervention and the diet and exercise intervention  yielded significant weight loss compared to the control . Following 12 weeks a reduction of ‐8.3 + /‐ 4.2 kg for diet intervention and ‐6.9 + /‐ 3.0 kg for diet and exercise was observed . Additionally after one year , the diet intervention showed ‐10.2 + /‐ 5.7 kg reduction and ‐7.3 + /‐ 6.3 kg for the diet and exercise intervention (p<0.001).24 Colleran et al. also found significant weight change results by implementing a 16‐week intervention which consisted of weekly individual sessions with a dietitian regarding calorie restriction , two additional home visits regarding exercise , weekly food diary completion and email support.25 The intervention group had greater weight loss compared to the control group ( ‐5.8 kg + /‐ 3.5 kg vs ‐1.6 kg + /‐ 5.4 kg ) . It can be seen that various methods have been utilized in investigating the impact of diet and physical activity interventions on PPWR . The review by van der Pligt et al.23 highlights the impact successful lifestyle interventions can have on postpartum weight change . However , this review did not investigate the different intervention strategies utilized . It remains unclear as to the optimal setting , delivery method , diet strategy , contact frequency or intervention length to limit PPWR . Previous systematic review s for both GWG and PPWR have focused on the effectiveness of lifestyle interventions as a whole for weight management in pregnant and postpartum women.20,23 And despite Tanentsapf et al. 's focus on dietary interventions for GWG,22 much is still unknown about the effectiveness of differing diet interventions over the antenatal and postpartum period . Specifically , the impact of differing diet intervention strategies on maternal weight gain is not known . Firstly , this systematic review will focus on whether  weight management interventions which include a dietary component  are effective in pregnant and postpartum women . In addition to this , this review will investigate the different intervention strategies utilized and their effectiveness in maternal weight management . A search of systematic review protocol data bases has shown that there is no current review underway for this topic Background Prevalence of  allergic diseases in infants , whose parents and siblings do not have allergy , is approximately 10 % and reaches 20–30 % in those with an allergic first-degree relative . Intestinal microbiota may modulate immunologic and inflammatory systemic responses and , thus , influence development of sensitization and allergy . Probiotics have been reported to modulate immune responses and their supplementation has been proposed as a preventive intervention . Objective The World Allergy Organization ( WAO ) convened a guideline panel to develop evidence -based recommendations about the use of probiotics in the prevention of allergy . Methods We identified the most relevant clinical questions and performed a systematic review of r and omized controlled trials of probiotics for the prevention of allergy . We followed the Grading of Recommendations Assessment , Development and Evaluation ( GRADE ) approach to develop recommendations . We search ed for and review ed the evidence about health effects , patient values and preferences , and re source use ( up to November 2014 ) . We followed the GRADE evidence -to-decision framework to develop recommendations . Results Currently available evidence does not indicate that probiotic supplementation  reduces the risk of developing allergy in children . However , considering all critical outcomes in this context , the WAO guideline panel determined that there is a likely net benefit from using probiotics result ing primarily from prevention of eczema . The WAO guideline panel suggests : a ) using probiotics in pregnant women at high risk for having an allergic child ; b ) using probiotics in women who breastfeed infants at high risk of developing allergy ; and c ) using probiotics in infants at high risk of developing allergy . All recommendations are conditional and supported by very low quality evidence . Conclusions WAO recommendations about probiotic supplementation for prevention of allergy are intended to support parents , clinicians and other health care professionals in their decisions whether to use probiotics in pregnancy and during breastfeeding , and whether to give them to infants The effect of practicing yoga for the management of type II Diabetes  was assessed in this systematic review through search ing related electronic data bases and the grey literature to the end of May 2007 using Ovid . All r and omized controlled clinical trials ( RCTs ) comparing yoga practice with other type of intervention or with regular practice or both , were included regardless of language or type of publication . Each study was assessed for quality by two independent review ers . Mean difference was used for summarizing the effect of each study outcomes with 95 % confidence intervals . Pooling of the studies did not take place due to the wide clinical variation between the studies . Publication bias was assessed by statistical methods . Five trials with 363 participants met the inclusion criteria with medium to high risk of bias and different intervention characteristics . The studies ’ results show improvement in outcomes among patients with diabetes type II .  These improvements were mainly among short term or immediate diabetes outcomes and not all were statistically significant . The results were inconclusive and not significant for the long-term outcomes . No adverse effects were reported in any of the included studies . Short-term benefits for patients with diabetes  may be achieved from practicing yoga . Further research is needed in this area . Factors like quality of the trials and other method ological issues should be improved by large r and omized control trials with allocation concealment to assess the effectiveness of yoga on diabetes type II . A definitive recommendation for physicians to encourage their patients to practice yoga can not be reached at present A growing body of scientific evidence has linked dairy intake to a reduced  type 2 diabetes ( T2D ) risk . Using an evidence -based approach , we review ed the most recent and strongest evidence on the relationship between dairy intake and the risk of T2D . Evidence indicates that dairy intake is significantly associated with a reduced T2D risk , and likely in a dose-response manner . The association between low-fat dairy and T2D risk reduction appears consistent . A beneficial impact is suggested for regular-fat dairy . The role of specific dairy products needs to be clarified . Potential underlying mechanisms include the role of dairy products in obesity and metabolic syndrome , as well as several dairy components , such as calcium , vitamin D , dairy fat , and specifically trans-palmitoleic acid . To conclude , there is strong , consistent , and accumulating evidence that dairy intake reduces the risk of T2D . More research is needed to better underst and the role of regular-fat and specific dairy products . Well- design ed r and omized controlled trials and mechanistic studies are needed to support these findings . Efforts to translate this evidence into clinical practice and public health guidance are needed Purpose There is research evidence which supports the effectiveness of exercise in reducing pain and increasing function in patients with patellofemoral pain syndrome . However , what is unclear are the parameters underpinning this intervention . This has led to uncertainty when operationalizing exercises for patients with patellofemoral pain syndrome in clinical practice . The aim of this review was to evaluate the parameters of exercise programs reported in primary research , to provide clinicians with evidence -based recommendations for exercise prescription for patellofemoral pain . Methods A systematic review of r and omized controlled trials was undertaken . Only trials that identified exercise to be effective in treating patellofemoral pain were included . Appropriate data bases and reference lists were search ed using established keywords . Data relating to common exercise parameters such as the type of exercise , length , and frequency of intervention , intensity , repetitions , sets , and specific technique were extracted , along with details of co- interventions that may have been used . Results A total of ten r and omized controlled trials were included in this review and from these trials 14 interventions arms were evaluated . All 14 interventions focused on active exercises , all but two of which also included a passive stretching component . The current body of evidence demonstrates positive results with exercise interventions such as  knee extension , squats , stationary cycling , static quadriceps , active straight leg raise , leg press , and step-up and down exercises  for patients with patellofemoral pain syndrome . A progressive regime of daily exercises of two to four sets of ten or more repetitions over an intervention period of 6 weeks or more , combined with exercises to address flexibility of the lower limb musculature was commonly used . Conclusion Currently , the primary research on this topic supports the use of closed kinetic chain , strengthening exercises for musculature of the lower limb , combined with flexibility options . The current evidence base supports a prescription of daily exercises of two – four sets of ten or more repetitions over a period of 6 weeks or more OBJECTIVE Plasma resistin level is a potential molecular link between obesity and diabetes . Causal role of resistin , type 2 diabetes mellitus ( T2DM ) and genetic variants have not been thoroughly investigated . Therefore , we conducted a genome-wide association study ( GWAS ) to identify quantitative trait loci associated with resistin levels and investigated whether these variants were prospect ively associated with the development of metabolic syndrome ( MetS ) and T2DM in an independent community-based cohort , the CardioVascular Disease risk FACtors Two-township Study ( CVDFACTS ) . RESEARCH DESIGN AND METHODS We genotyped 382 young-onset hypertensive ( YOH ) subjects with Illumina HumanHap550 chips and search ed for quantitative trait loci ( QTLs ) of resistin in the 1(st ) stage GWAS and confirmed the finding in another 559 YOH subjects . Logistic regression was used to examine the Mendelian r and omization effects between genotypes of confirmed QTLs and metabolic outcomes in 3400 subjects of CVDFACTS . RESULTS Two single nucleotide polymorphisms ( SNP ) ( rs3745367 and rs1423096 ) were significantly associated with resistin levels ( p = 5.52 × 10(-15 ) and p = 2.54 × 10(-20 ) ) and replicated in another 559 YOH subjects ( p = 1.29 × 10(-3 ) and p = 1.13 × 10(-7 ) ) , respectively . The SNP rs1423096 was further associated with the levels of HDL-C ( p = 0.006 ) , the risk of MetS ( OR = 2.21 , p = 0.0034 ) and T2DM ( OR = 1.62 , p = 0.0063 ) in the CVDFACTS . People with the haplotypes A-G and G-G determined by rs3745367 and rs1423096 showed a significantly increased T2DM risk ( p = 0.0068 and p = 0.0035 , respectively ) compared with those with A-A haplotype . CONCLUSION We have found that rs3745367 and rs1423096 on the RETN gene were significantly associated with resistin levels . However , rs1423096 , downstream of RETN , seems to be associated with MetS and T2DM risk more so than rs3745367 . The established genotype-disease association points to a causal association of resistin and T2DM PURPOSE Few culturally competent health programs have been design ed for Mexican Americans , a group that bears a disproportionate burden of Type 2 diabetes . In Starr County , a Texas-Mexico border community , investigators design ed and tested a culturally competent intervention aim ed at improving the health of this target population . The purpose of this article is to describe the development process of this diabetes education and support group intervention . METHODS The development stages were ( 1 ) community assessment , ( 2 ) intervention design , ( 3 ) selection or development of outcomes , ( 4 ) pilot testing , and ( 5 ) a r and omized clinical investigation . RESULTS Focus group participants identified knowledge deficits regarding diabetes and self-management strategies , and suggested characteristics of an effective intervention for Mexican Americans . Outcome measures included metabolic control indicators , a newly developed knowledge instrument , and an existing health belief instrument . Preliminary analyses indicated that the intervention was successful in significantly improving metabolic control in the target population . CONCLUSIONS Developing successful diabetes interventions for minority groups requires a number of stages , careful planning , assessment of cultural characteristics of the target population , and a systematic approach to implementation BACKGROUND Probiotics have beneficial effect on obesity related disorders in animal models . Despite a large number of animal data , r and omized placebo-controlled trials ( RCT ) concluded that probiotics have a moderate effect on glycemic control-related parameters . However , effect of probiotics on insulin resistance are inconsistent . AIM In a double-blind single center RCT , effect of alive multistrain probiotic vs. placebo on insulin resistance in type 2 diabetes patient were assessed . METHODS A total of 53 patients met the criteria for inclusion . They were r and omly assigned to receive multiprobiotic " Symbiter " ( concentrated biomass of 14 probiotic bacteria genera Bifidobacterium , Lactobacillus , Lactococcus , Propionibacterium ) or placebo for 8-weeks administered as a sachet formulation . The primary main outcome was the change HOMA-IR ( homeostasis model assessment -estimated insulin resistance ) which calculated using Matthews et al. 's equation . Secondary outcomes were the changes in glycemic control-related parameters , anthropomorphic variables and cytokines . RESULTS Supplementation with alive multiprobiotic for 8 weeks was associated with significant reduction of HOMA-IR from 6.85 ± 0.76 to 5.13 ± 0.49 ( p = 0.047 ) , but remained static in the placebo group . With respect to our secondary outcomes , HbA1c insignificant decreased by 0.09 % ( p = 0.383 ) and 0.24 % ( p = 0.068 ) respectively in placebo and probiotics groups . However , in probiotic responders ( n = 22 , patient with decrease in HOMA-IR ) after supplementation a significant reduction in HbA1c by 0.39 % ( p = 0.022 ) as compared to non-responders was observed . In addition , from markers of chronic systemic inflammatory state only TNF-α and IL-1β changes significantly after treatment with probiotics . CONCLUSION Probiotic therapies modestly improved insulin resistance in patients with type 2 diabetes Objectives : This umbrella review aim ed to determine the effectiveness of exercise interventions , alone or in combination with other interventions , in improving physical function in community-dwelling older people identified as pre-frail or frail . Introduction : Exercise is said to have a positive impact on muscle mass and strength which improves physical function and hence is beneficial for the treatment of frailty . Several systematic review s discuss the effects of exercise interventions on physical function parameters , such as strength , mobility , gait , balance and physical performance , and indicate that multi-component exercise , including resistance , aerobic , balance and flexibility training , appears to be the best way in which to improve physical function parameters in frail older people . However , there is still uncertainty as to which exercise characteristics ( type , frequency , intensity , duration and combinations ) are the most effective and sustainable over the long-term . Inclusion criteria : Participants were adults , 60 years or over , living in the community and identified as pre-frail or frail . Quantitative systematic review s , with or without meta- analysis that examined the effectiveness of exercise interventions of any form , duration , frequency and intensity , alone or in combination with other interventions design ed to alter physical function parameters in frail older people , were considered . The quantitative outcome measures were physical function , including muscular strength , gait , balance , mobility and physical performance . Methods : An iterative search strategy for ten bibliometric data bases and gray literature was developed . Critical appraisal of seven systematic review s was conducted independently by two review ers using a st and ard Joanna Briggs Institute tool . Data was extracted independently by two review ers using a st and ard Joanna Briggs Institute data extraction tool and summarized using a narrative synthesis approach . Results : Seven systematic review s were included in this umbrella review , with a total of 58 relevant r and omized controlled trials and 6927 participants . Five systematic review s examined the effects of exercise only , while two systematic review s reported on exercise in combination with a nutritional approach , including protein supplementations , as well as fruit and dairy products . The average  exercise frequency was 2–3 times per week ( mean 3.0 ± 1.5 times per week ; range 1–7 weekly ) for 10–90 minutes per session ( mean of 52.0 ± 16.5 mins ) and a total duration of 5–72 weeks with the majority lasting a minimum of 2.5 months ( mean 22.7 ± 17.7 weeks ) . Multi-component exercise interventions can currently be recommended for pre-frail and frail older adults to improve muscular strength , gait speed , balance and physical performance , including resistance , aerobic , balance and flexibility tasks . Resistance training alone also appeared to be beneficial , in particular for improving muscular strength , gait speed and physical performance . Other types of exercise were not sufficiently studied and their effectiveness is yet to be established . Conclusions : Interventions for pre-frail and frail older adults should include multi-component exercises , including in particular resistance training , as well as aerobic , balance and flexibility tasks . Future research should adopt a consistent definition of frailty and investigate the effects of other types of exercise alone or in combination with nutritional interventions so that more specific recommendations can be made Aims : With the increase in the number of systematic review s available , a logical next step to provide decision makers in healthcare with the evidence they require has been the conduct of review s of existing systematic review s. Syntheses of existing systematic review s are referred to by many different names , one of which is an umbrella review . An umbrella review allows the findings of review s relevant to a review question to be compared and contrasted . An umbrella review 's most characteristic feature is that this type of evidence synthesis only considers for inclusion the highest level of evidence , namely other systematic review s and meta-analyses . A methodology working group was formed by the Joanna Briggs Institute to develop method ological guidance for the conduct of an umbrella review , including diverse types of evidence , both quantitative and qualitative . The aim of this study is to describe the development and guidance for the conduct of an umbrella review . Methods : Discussion and testing of the elements of methods for the conduct of an umbrella review were held over a 6-month period by members of a methodology working group . The working group comprised six participants who corresponded via teleconference , e-mail and face-to-face meeting during this development period . In October 2013 , the methodology was presented in a workshop at the Joanna Briggs Institute Convention . Workshop participants , review authors and method ologists provided further testing , critique and feedback on the proposed methodology . Results : This study describes the methodology and methods developed for the conduct of an umbrella review that includes published systematic review s and meta-analyses as the analytical unit of the review . Details are provided regarding the essential elements of an umbrella review , including presentation of the review question in a Population , Intervention , Comparator , Outcome format , nuances of the inclusion criteria and search strategy . A critical appraisal tool with 10 questions to help assess risk of bias in systematic review s and meta-analyses was also developed and tested . Relevant details to extract from included review s and how to best present the findings of both quantitative and qualitative systematic review s in a reader friendly format are provided . Conclusions : Umbrella review s provide a ready means for decision makers in healthcare to gain a clear underst and ing of a broad topic area . The umbrella review methodology described here is the first to consider review s that report other than quantitative evidence derived from r and omized controlled trials . The methodology includes an easy to use and informative summary of evidence table to readily provide decision makers with the available , highest level of evidence relevant to the question posed
Probiotics intake in patients with MetS result ed in improvements in body mass index , blood pressure , glucose metabolism , and lipid profile in some studies .
Regarding inflammatory biomarkers , probiotics also positively affected the soluble vascular cell adhesion molecule 1 ( sVCAM-1 ) , interleukine-6 ( IL-6 ) , tumor necrosis factor α ( TNF-α ) , vascular endothelial growth factor ( VEGF ) , and thrombomodulin .
Despite the diversity of the published studies , the intake of probiotics for patients with MetS may offer a discrete improvement in some of the clinical characteristics of the MetS and a decrease in inflammatory biomarkers .
The aim of this systematic review is to evaluate whether the use of probiotics has any effect on the components of metabolic syndrome ( MetS ) before patients develop type 2 diabetes .
