Job morale: a scoping review of how the concept developed and is used in healthcare research
Authors: Sabitova Alina , Hickling Lauren M. , Priebe Stefan
Published: July 2020

Background

The job morale of healthcare staff is widely seen as an important factor for the quality of care. Yet, there are different understandings of what constitutes job morale, which hinders systematic research and comparisons. We therefore conducted a scoping review of how the concept of job morale has developed over time and how it is used in healthcare research.

Methods

A scoping review was conducted to identify relevant literature. Data were gathered on study design and context, objectives, definitions of morale, outcome measures and key findings. Data was synthesised using a descriptive analytical framework.

Results

Ninety-three unique studies met eligibility criteria for the present review. The literature outlines four main periods of the evolution of the concept of job morale: The First World War and the interwar years; Second World War; Aftermath of the Second World War; and Contemporary period. The concept of job morale originated in a military context and was later applied to and specified in the healthcare literature. The concept has been applied to individuals and groups. The understandings used in healthcare vary, but overlap. Methods for assessing job morale in healthcare include quantitative scales, indirect measurements of consequences and predictors of morale, and qualitative approaches. Existing studies have mainly focused on the job morale of general practitioners, nurses and mental health professionals in high-income countries.

Conclusions

Although the understandings of job morale in healthcare are heterogeneous and inconsistent, the concept appears to have been useful over longer periods of time and in different contexts. Which precise understanding of job morale is useful, depends on the given research purpose, and studies should make explicit which exact understanding they apply. Systematic research on job morale is required to facilitate measures to improve and maintain high levels of morale across different professional groups, including professionals in low- and middle-income countries.

Published: July 2020

Background

High rate of teenage pregnancy in Nigeria is potentially an indication of poor access to and utilization of contraceptives among this age group. This paper presents findings from in-depth exploration of perceived barriers to utilization of contraceptive services by adolescents.

Methods

A qualitative study was conducted in six communities in Ebonyi state, southeast Nigeria. Eighty-one in-depth interviews and six focus group discussions were conducted. Respondents comprised policy makers, community leaders, health service providers and parents of adolescents. Pre-tested interview guides were used to collect information on perceived barriers to utilization of contraceptive services by adolescents. All interviews were audio recorded and transcribed in English. Data was analysed using thematic framework approach, and the socio-ecological model was adapted for data synthesis.

Results

Individual level factors that limit access to contraceptives for adolescents include lack of awareness and poor knowledge, fear of side effects, low self-esteem, and inability to afford cost of services. Interpersonal (family-related) barriers to access include poor parent-child communication of sexual and reproductive health matters and negative attitude of parents towards to sexuality education for adolescents. Health systems barriers to accessing contraceptives for adolescents include lack of privacy and confidentiality, stock-out of contraceptive commodities, judgmental attitude of health workers, insufficient staff that are skilled in adolescent sexual and reproductive health. Gendered cultural norms, societal shaming and religious intolerance also preclude adolescents from accessing and using contraceptive services. Wider societal factors such as negative peer and media influence, absence of sexuality education in schools, lack of social networks in communities; and macro level factors such as poor economic conditions were also perceived to limit access to contraceptives for adolescents.

Conclusion

Utilization of contraception is constrained by an interplay of factors acting at various levels. Addressing these barriers could contribute to improved access to contraceptive services for adolescents, as well as reduction in unwanted teenage pregnancy.

Authors: Jia Lu , Lu Haiwen , Wu Jing , Wang Xuemei , Wang Wenrui , Du Maolin , Wang Peiyu , Du Sha , Su Yuenan , Zhang Nan
Published: July 2020

Background

Obesity is a major risk factor for the global burden of disease in countries that are economically developed or not. This study aimed to investigate the association between diet quality and obesity indicators applying DASH and aMed.

Methods

This cross-sectional study on adult nutrition and chronic disease in Inner Mongolia (n = 1320). Dietary data were collected using 24-h diet recall for 3 consecutive days and weighing method. DASH and aMed were used to assess the dietary quality. WC, BMI and WC-BMI were used as obesity indicators. Logistic regression models were used to examine the associations between diet quality and obesity indicators.

Results

Higher diet quality, assessed by DASH, was only associated with WC. The odds ratio (OR) for abdominal obesity in the highest tertile of DASH scores compared with the lowest was 0.71 (95% confidence interval (CI) 0.53, 0.96; Ptrend = 0.03). Furthermore, aMed was inversely associated with obesity indicators. OR for abdominal obesity in the highest tertile of aMed score compared with the lowest were 0.63 (95% CI 0.47, 0.87; Ptrend = 0.005) and 0.57 (95% CI 0.41, 0.77; Ptrend = 0.02) for overweight and obesity, respectively, and 0.60 (95% CI 0.44, 0.81; Ptrend = 0.02) for high obesity risk.

Conclusions

Our findings suggest that dietary quality assessed using aMed is more closely associated with obesity than assessment using DASH in working-age adults in Inner Mongolia. The Mediterranean diet can be recommended as a healthy diet to control weight.

Published: July 2020

Background

Wound healing complications are causal factors of prosthesis infection and poor postoperative evolution of patients after total knee arthroplasty (TKA). Negative-pressure wound therapy (NPWT) can be an option to minimize these complications. The aim of this study is to compare the complications of patients undergoing TKA who used a portable NPWT device in the immediate postoperative period with those of a control group.

Methods

A total of 296 patients were evaluated. Patients were divided into two groups: those who used NPWT for seven days in the postoperative period (Group 1 – prospective evaluated) and those who used conventional dressings (Group 2 – historical control group). Epidemiological data, comorbidities, local parameters related to the surgical wound and complications were evaluated.

Results

The groups did not differ in regard to sex, age and clinical comorbidities. Overall, 153 (51.7%) patients had at least one risk factor for wound complications. Patients who used NPWT had a lower rate of complications (28.5% vs. 45.7%, p = 0.001) and a lower rate of reintervention in the operating room (2% vs. 8.5%, p = 0.001). Patients in group 1 had a lower incidence of hyperaemia (14.7% vs. 40.2%, p = 0.01), skin necrosis (2.1% vs. 8.5%, p = 0.04) and wound dehiscence (3.1% vs 10.1%, p = 0.03). The use of NPWT was a protective factor for the presence of complications, with an odds ratio of 0.36 (95% CI 0.206–0.629).

Conclusion

The number of complications related to the wound after TKA is high; however, most of them are minor and have no impact on the treatment and clinical evolution of patients. The use of NPWT decreased the number of surgical wound complications, especially hyperaemia, dehiscence and necrosis, and reduced the need for reintervention.
Muscle activation patterns during backward walking in people with chronic ankle instability
Authors: Balasukumaran Tharani , Gottlieb Uri , Springer Shmuel
Published: July 2020

Background

Altered walking patterns are often described in individuals with chronic ankle instability (CAI). Contemporary treatment paradigms recommend backward walking (BW) to improve locomotion in people with musculoskeletal disorders. The purpose of this study was to determine whether muscle activity and activation variability during BW differs between subjects with and without CAI.

Methods

Sixteen participants with CAI and 16 healthy controls walked on a treadmill at their self-selected speed under BW and forward walking (FW) conditions. Surface electromyography (EMG) data for the peroneus longus, tibialis anterior, medial gastrocnemius and gluteus medius muscles were collected. EMG amplitude normalized to maximum voluntary isometric contraction (%MVIC) and the standard deviation (SD) of the %MVIC EMG amplitude was calculated throughout the gait cycle. In addition, the area under the curve (AUC) of the %MVIC EMG amplitude was calculated before and after initial contact (pre-IC: 90–100% of stride; post-IC: 0–10% of stride).

Results

No differences between groups were noted in the %MVIC amplitude or activation variability (SD of %MVIC EMG) under BW or FW. In both groups, decreased tibialis anterior (p < 0.001) and gluteus medius (p = 0.01), and increased medial gastrocnemius (p < 0.001) activation were observed during pre- and post-IC under BW condition.

Conclusion

Participants with CAI and healthy controls have similar muscle activity patterns during BW. Yet, the results should be interpreted with caution due to the heterogeneity of the CAI population.
The lateral center-edge angle as radiographic selection criteria for periacetabular osteotomy for developmental dysplasia of the hip in patients aged above 13 years
Authors: Zhang Daguang , Pan Xin , Zhang Hong , Luo Dianzhong , Cheng Hui , Xiao Kai
Published: July 2020

Background

This retrospective study sought to delineate the radiographic characteristics of DDH patients over 13 years of age and investigate whether the lateral center-edge angle (LCEA) could serve as radiographic selection criteria for periacetabular osteotomy.

Methods

We enrolled patients with Hartofilakidis type I DDH without dislocation who underwent periacetabular osteotomy between August 2009 and August 2012. LCEA, anterior central edge angle (ACEA), femoral neck-shaft angle (FNSA), Shenton line and Tönnis acetabular index (AI) were evaluated by anteroposterior and 65° false⁃profile pelvic X-ray radiographs in the standing position. Femoral neck anteversion angle (FNA), labral lesion, labral inversion and cartilage lesion were evaluated by direct magnetic resonance arthrography. DDH was categorized by LCEA into four grades (grade I: 10° ≤ LCEA< 20°, grade II: 0° ≤ LCEA< 10°, grade III: -10° ≤ LCEA< 0°, grade IV: LCEA<-10) and osteoarthritis (OA) severity was assessed using Tönnis OA classification. Pearson correlation analysis was done between LCEA and other variables.

Results

Totally patients (274 hips) with a mean age of 27.3 years (range 13–47 years) were included. The mean LCEA was 3.5° (range: − 30° to 20°). Based on LCEA grades, grade I DDH was present in 104 hips, grade II in 40 hips, grade III in 76 hips, and grade IV in 54 hips. Based on Tönnis OA classification, 54.5% hips (150/274) were grade 0, 33.1% hips (91/274) grade 1, 8.4% hips (23/274) grade 2 and 4% hips (11/274) grade 3. Pearson correlation analysis showed a negative correlation between LCEA grade and Tönnis OA grades (r = 0.3987; P < 0.001). Cochran-Armitage trend test further showed a positive correlation between LCEA grades and labral lesion (P < 0.001) and interrupted Shenton line (P < 0.001).

Conclusion

The LCEA classification scheme offers a simple and practical approach to categorize the level of acetabulum coverage on the femoral head, hip deformity and characteristics of DDH. Our findings could provide clinically useful guidance for orthopedic surgeons in preparation for periacetabular osteotomy in DDH patients aged above 13 years.
Laparoscopic versus open surgery for pheochromocytoma: a meta-analysis
Authors: Fu Sheng-Qiang , Wang Si-Yuan , Chen Qiang , Liu Yu-Tang , Li Zhi-Long , Sun Ting
Published: July 2020

Background

Surgical resection is the main treatment for pheochromocytoma (PHEO). Although open surgery (OS) has been shown to be safe and feasible, the safety and efficacy of laparoscopic surgery (LS) for PHEO remain controversial due to the uncertain effects of pneumoperitoneum on haemodynamics and the complexity of the tumour itself. This study was performed to compare the treatment outcomes of OS with those of LS for patients with PHEO.

Methods

A systematic search through November 11, 2019, was conducted. All studies comparing outcomes of LS and OS for PHEO were included according to eligibility criteria. This meta-analysis was conducted using Review Manager Software, version 5.3, and STATA software, version 12.0. The quality of the included studies was assessed using the Newcastle-Ottawa scale.

Results

Fourteen studies involving 626 patients were included in this meta-analysis. LS was associated with lower rates of intraoperative haemodynamic instability (IHD) [odds ratio (OR) = 0.61, 95% CI: 0.37 to 1.00, P = 0.05], less intraoperative blood loss [weighted mean difference (WMD) = − 115.27 ml, 95% confidence interval (CI): − 128.54 to − 101.99, P < 0.00001], lower blood transfusion rates [OR = 0.33, 95% CI: 0.21 to 0.52, P < 0.00001], earlier ambulation (WMD = − 1.57 d, 95% CI: − 1.97 to − 1.16, P < 0.00001) and food intake (WMD = − 0.98 d, 95% CI: − 1.36 to − 0.59, P < 0.00001), shorter drainage tube indwelling time (WMD = − 0.51 d, 95% CI: − 0.96 to − 0.07, P = 0.02) and postoperative stay (WMD = − 3.17 d, 95% CI: − 4.76 to − 1.58, P < 0.0001), and lower overall complication rates (OR = 0.56, 95% CI: 0.35 to 0.88, P = 0.01). However, no significant differences in operative time, postoperative blood pressure control, rates of severe complications, postoperative hypotension or cardiovascular disease (CVD) were found between the two groups.

Conclusions

LS is safe and effective for PHEO resection. Compared with OS, LS caused less IHD, providing an equal chance to cure hypertension while also yielding a faster and better postoperative recovery.

Published: July 2020

Background

Adhesive small bowel obstruction (ASBO) is one of the most common causes of postoperative morbidity. According to Boyle’s law, decreased barometric pressure expands the volume of intestinal gas. We aimed to elucidate the relationship between barometric pressure and ASBO.

Methods

We divided 215 admissions of 120 patients with ASBO into three groups: the fasting group, which responded to fasting (n = 51); the decompression group, which was successfully treated with gastrointestinal decompression (n = 104); and the surgery group which required emergency or elective surgery to treat ASBO (n = 60). We compared and examined clinical backgrounds, findings on admission, and barometric pressure during the peri-onset period (29 days: from 14 days before to 14 days after the onset of ASBO).

Results

There were significant differences among the three groups regarding gender, history of ASBO, hospital length of stay, and barometric pressure on the onset day of ASBO. Barometric pressure on the onset day was significantly higher in the fasting group than in the decompression group (p = 0.005). During pre-onset day 5 to post-onset day 2, fluctuations in the barometric pressure in the fasting and decompression groups showed reciprocal changes with a symmetrical axis overlapping the median barometric pressure in Matsumoto City; the fluctuations tapered over time after onset. In the fasting group, the barometric pressure on the onset day was significantly higher than that on pre-onset days 14, 11, 7, 4, 3, and 2; post-onset days 3 and 10; and the median pressure in Matsumoto City. Conversely, in the decompression group, the barometric pressure on the onset day was lower than that on pre-onset days 14, 5–2; post-onset days 1, 2, 7, 8, 11, 13, and 14; and the median pressure in Matsumoto City. In the surgery group, the barometric pressure on the onset day was equivalent to those on the other days.

Conclusions

ASBO with response to conservative treatment is vulnerable to barometric pressure. Additionally, ASBO that is successfully treated with fasting and decompression is associated with a different barometric pressure on the onset day and reciprocal fluctuations in the barometric pressure during the peri-onset period.

Published: July 2020

Background

The neutrophil-lymphocyte ratio (NLR) is a well-known prognostic marker in various cancers. However, its role as a predictive marker for the effectiveness of nivolumab in patients with metastatic RCC (mRCC) remains unclear. We evaluated the relationships between the NLR and progression-free survival (PFS) or overall survival (OS) in mRCC patients treated with nivolumab.

Methods

The data of 52 mRCC patients who received nivolumab therapy were collected from seven institutes and evaluated. The median follow-up period from treatment with nivolumab was 25.2 months (IQR 15.5–33.2).

Results

The median duration of nivolumab therapy was 7.1 months (IQR 2.9–24.4). The objective response rate was 25% and the 1- and 2-year PFS rates were 46.2 and 25.2%, respectively. The median NLR values at baseline and 4 weeks were 3.7 (IQR 2.7–5.1) and 3.3 (IQR 2.4–5.7), respectively. In the multivariate analysis, an NLR of ≥3 at 4 weeks was an independent predictor of PFS (P = 0.013) and OS (P = 0.034). The 1-year PFS of patients with an NLR of < 3 at 4 weeks was better than that of those with an NLR of ≥3 (75% versus 29%, P = 0.011). The 1-year OS of patients with an NLR of < 3 at 4 weeks was also better than that of those with an NLR of ≥3 (95% versus 71%, P = 0.020).

Conclusions

Although the baseline NLR was not associated with PFS or OS, an NLR of ≥3 at 4 weeks after the initiation of therapy might be a robust predictor of poor PFS and OS in mRCC patients undergoing sequential treatment with nivolumab.
Characterization and genomic analysis of a diesel-degrading bacterium, Acinetobacter calcoaceticus CA16, isolated from Canadian soil
Authors: Ho Margaret T. , Li Michelle S. M. , McDowell Tim , MacDonald Jacqueline , Yuan Ze-Chun
Published: July 2020

Background

With the high demand for diesel across the world, environmental decontamination from its improper usage, storage and accidental spills becomes necessary. One highly environmentally friendly and cost-effective decontamination method is to utilize diesel-degrading microbes as a means for bioremediation. Here, we present a newly isolated and identified strain of Acinetobacter calcoaceticus (‘CA16’) as a candidate for the bioremediation of diesel-contaminated areas.

Results

Acinetobacter calcoaceticus CA16 was able to survive and grow in minimal medium with diesel as the only source of carbon. We determined through metabolomics that A. calcoaceticus CA16 appears to be efficient at diesel degradation. Specifically, CA16 is able to degrade 82 to 92% of aliphatic alkane hydrocarbons (CnHn + 2; where n = 12–18) in 28 days. Several diesel-degrading genes (such as alkM and xcpR) that are present in other microbes were also found to be activated in CA16.

Conclusions

The results presented here suggest that Acinetobacter strain CA16 has good potential in the bioremediation of diesel-polluted environments.
The knowledge and practice of pediatricians in children’s oral health: a scoping review
Authors: Dickson-Swift Virginia , Kenny Amanda , Gussy Mark , McCarthy Colleen , Bracksley-O’Grady Stacey
Published: July 2020

Background

Dental caries is a significant public health problem and one of the most common chronic conditions affecting children. The potential for the non-dental workforce to improve children’s oral health is well documented. For well over a decade, there have been calls for pediatricians to address children’s oral health, but the incorporation of oral health screening, referral, and oral healthcare in pediatric practice remains underdeveloped. Developing action to strengthen the role of pediatricians’ in children’s oral health requires an understanding of their current knowledge and practice. In this scoping review, we aimed to comprehensively map what is known about the knowledge and practice of pediatricians regarding children’s oral health.

Methods

Arksey & O’Malley’s five-stage review process was used to comprehensively map studies undertaken on pediatrician’s knowledge and practice regarding children’s oral health. Key search terms were developed and a total of 42 eligible articles are included in the review.

Results

The studies were conducted in 19 countries. The majority (41/42) were quantitative, with over 90% using self-reported surveys. Only four studies used previously validated survey tools, with most adapting questions from previous studies. Observational designs were used in two studies and one used qualitative methods. Sample size ranged from 15 to 862. Oral health knowledge amongst pediatricians was reported to be mostly poor, with many gaps in key areas including age for first dental visit, dental caries and oral health risk assessments. Studies on the translation of oral health knowledge to practice were limited, with wide variation in rates of assessment. Few studies assessed actual practice.

Conclusions

This scoping review highlights growing international interest in the role of pediatricians in children’s oral health. Findings demonstrate that pediatricians have limited knowledge and understanding in critical areas, including; initial clinical signs of dental caries, recommended age for first dental visit, etiology of dental caries and recommended use of fluorides. Barriers for pediatricians include inadequate education and training, time constraints in practice and lack of referral pathways. Development of a validated tool to assess knowledge and practice is needed. This review provides a starting point to guide future research and areas for systematic reviews.

Published: July 2020

Background

Long-acting (LA) injectable antiretroviral therapy (ART) has been found non-inferior to daily oral ART in Phase 3 trials. LA ART may address key barriers to oral ART adherence and be preferable to daily pills for some people living with HIV. To date, women have been less represented than men in LA ART research. Using longitudinal data from the Women’s Interagency HIV Study (WIHS) cohort of women living with HIV in the United States, we examined barriers and facilitators of daily oral ART adherence that may be related to or addressed by LA ART.

Methods

We conducted a secondary analysis of WIHS cohort data from 1998 to 2017 among participants seen for at least 4 visits since 1998 who reported using ART at least once (n = 2601). Two dichotomous outcomes, patient-reported daily oral ART adherence and viral suppression were fit using generalized linear models, examining the role of socio-demographic and structural factors.

Results

At study enrollment, the median age was 40.5 years, 63% of participants were African American and 22% were Latina. The majority (82%) reported taking ART more than 75% of the time and 53% were virally suppressed. In multivariate analysis, several sub-groups of women had lower odds of reported adherence and viral suppression: 1) younger women (adherence aOR: 0.71; viral suppression aOR: 0.63); 2) women who inject drugs (adherence aOR: 0.38; viral suppression aOR: 0.50) and those with moderate (adherence aOR: 0.59; viral suppression aOR: 0.74) and heavy alcohol consumption (adherence aOR: 0.51; viral suppression aOR: 0.69); 3) those with depressive symptoms (adherence aOR: 0.61; viral suppression aOR: 0.76); and 4) those with a history of going on and off ART (adherence aOR: 0.62, viral suppression aOR: 0.38) or changing regimens (adherence aOR: 0.83, viral suppression aOR: 0.56).

Conclusions

Current injectable contraceptive users (vs. non-users) had greater odds of oral ART adherence (aOR: 1.87) and viral suppression (aOR: 1.28). Findings identify profiles of women who may benefit from and be interested in LA ART. Further research is warranted focused on the uptake and utility of LA ART for such key subpopulations of women at high need for innovative approaches to achieve sustained viral suppression.

Published: July 2020

Background

Analgesic, anti-inflammatory, and sedative drugs are available with potential side effects such as peptic ulcer and addiction among other things. In this regard, research is underway to find safe, effective, and economical drugs free of these side effects. In this study, an isolated natural product fromDiospyros lotus, was tested for the aforementioned bioactivities.

Objectives

To evaluate analgesic, anti-inflammatory, and sedative potential ofD. lotusextracts in animal paradigms using BALB/c mice as experimental model.

Methods

Analgesic, anti-inflammatory and sedative activities of dinaphthodiospyrol G (1) isolated from the chloroform fraction ofD. lotuswere evaluated using different experimental procedures. Anti-inflammatory effect was evaluated using the carrageenan and histamine-induced paw edema, whereas the antinociceptive effect was quantified by means of the hot plate analgesiometer. On the other hand, the sedative effect was determined using animal assay for screening the locomotors effects of compound1. Compound1was also subjected to molecular modeling studies against cyclooxygenase enzymes.

Results

Results from this investigation showed that the extract is devoid of anti-inflammatory and antinociceptive potentials but has a significant sedative effect, whereas the tested compound exhibited 55.23 and 78.34% attenuation in paw edema by carrageenan and histamine assays, respectively. A significant (p < 0.001) and dose-dependent antinociceptive and sedative effects were demonstrated by the isolated compound. Molecular docking and dynamics simulation studies of the isolated compound against cyclooxygenase enzyme indicated that compound1forms specific interactions with key residues in the active site of the target receptor, which validates the potential use of the isolated compound as cyclooxygenase inhibitor.

Conclusions

Compound1exhibited remarkable analgesic, anti-inflammatory, and sedative activities. These findings strongly justify the traditional use ofD. lotusin the treatment of inflammation, pain, and insomnia.
Factors associated with the perceived barriers of health care access among reproductive-age women in Ethiopia: a secondary data analysis of 2016 Ethiopian demographic and health survey
Authors: Tamirat Koku Sisay , Tessema Zemenu Tadesse , Kebede Fentahun Bikale
Published: July 2020

Background

Health care access is the timely use of personal health services to achieve the best health outcomes. Problems in accessing health care among reproductive-age may lead to various adverse health outcomes like death and disabilities. Therefore, this study aimed to identify factors associated with the perceived barriers of healthcare access among reproductive-age women in Ethiopia.

Method

This study was based on secondary data sources from the 2016 Ethiopia Demography and Health Survey. The individual women record (IR) file was used to extract about 15, 683 women for the final analysis from the largest dataset. A composite variable of health care access was created from four questions used to rate health care access problems among women of reproductive age. To identify factors associated with the perceived barriers of health care access among reproductive-age women, generalized estimating equation (GEE) model was fitted. Crude and adjusted odds ratio (AOR) with a 95% confidence interval (CI) computed to assess the strength of association between independent and outcome variables.

Results

This study revealed that the magnitude of perceived barriers of healthcare access among reproductive-age women was 69.9% with 95%CI (69.3 to 70.7) to at least one or more of the four reasons. Rural resident (AOR = 2.13, 95%CI: 1.79 to 2.53), age 35–49 years (AOR = 1.24, 95%CI: 1.09 to 1.40), divorced/separated (AOR = 1.34, 95%CI: 1.17 to 1.54), had no health insurance coverage (AOR = 1.19, 95%CI: 1.01 to 1.45), poorer (AOR = 2.09,95%CI: 1.86 to 2.35) and middle wealth (AOR = 1.57,95%CI:1.38 to 1.79), no education (AOR = 2.30, 95%CI:1.95 to 2.72), primary education (AOR = 1.84, 95%CI: 1.58 to 2.15) and secondary education (AOR = 1.31, 95%CI: 1.13 to 1.51) were factors associated with the perceived barriers of health care access.

Conclusion

A significant proportion of women of reproductive age faced barriers to healthcare access, of which money and distance were the most frequently perceived barriers. Divorced/separated marital status, old age, rural dwelling, no health insurance coverage, low economic situation, and level of education were factors associated with perceived barriers. These findings suggest further strengthening and improving health care access to those women with low socio-economic status for the realization of universal health coverage.

Published: July 2020

Background

Obstructive sleep apnea (OSA) is defined by frequent episodes of reduced or complete cessation of airflow during sleep and is linked to negative health outcomes. Understanding the genetic factors influencing expression of OSA may lead to new treatment strategies. Electronic health records (EHRs) can be leveraged to both validate previously reported OSA-associated genomic variation and detect novel relationships between these variants and comorbidities.

Methods

We identified candidate single nucleotide polymorphisms (SNPs) via systematic literature review of existing research. Using datasets available at Geisinger (n = 39,407) and Vanderbilt University Medical Center (n = 24,084), we evaluated associations between 40 previously implicated SNPs and OSA diagnosis, defined using clinical codes. We also evaluated associations between these SNPs and OSA severity measures obtained from sleep reports at Geisinger (n = 6571). Finally, we used a phenome-wide association study approach to help reveal pleiotropic genetic effects between OSA candidate SNPs and other clinical codes and laboratory values available in the EHR.

Results

Most previously reported OSA candidate SNPs showed minimal to no evidence for associations with OSA diagnosis or severity in the EHR-derived datasets. Three SNPs inLEPR,MMP-9, andGABBR1validated for an association with OSA diagnosis in European Americans; the SNP inGABBR1was associated following meta-analysis of results from both clinical populations. TheGABBR1andLEPRSNPs, and one additional SNP, were associated with OSA severity measures in European Americans from Geisinger. Three additional candidate OSA SNPs were not associated with OSA-related traits but instead with hyperlipidemia and autoimmune diseases of the thyroid.

Conclusions

To our knowledge, this is one of the largest candidate gene studies and one of the first phenome-wide association studies of OSA genomic variation. Results validate genetic associates with OSA in theLEPR, MMP-9andGABBR1genes, but suggest that the majority of previously identified genetic associations with OSA may be false positives. Phenome-wide analyses provide evidence of mediated pleiotropy. Future well-powered genome-wide association analyses of OSA risk and severity across populations with diverse ancestral backgrounds are needed. The comprehensive nature of the analyses represents a platform for informing future work focused on understanding how genetic data can be useful to informing treatment of OSA and related comorbidities.

Background

Maternal obesity is an emerging problem in the modern world. Growing evidence suggests that intrauterine high-fat (HF) exposure may predispose progeny to subsequent metabolic challenges. Progeny born to mothers who ate an HF diet also tends to eat an HF diet when growing and aggravate metabolic issues. Thus, the generational transmission of obesity is cyclical. Developing a strategy to prevent the occurrence of metabolic syndrome related to prenatal and/or postnatal HF diet is important. In this study, the reprogramming effects of maternal resveratrol treatment for the progeny with maternal HF/postnatal HF diets were investigated.

Methods

Sprague-Dawley dams were fed either a control or a high-fat/high sucrose diet (HFHS) from mating to lactation. After weaning, the progeny was fed chow or an HF diet. Four experimental groups were yielded: CC (maternal/postnatal control diet), HC (maternal HF/postnatal control diet), CH (maternal control/postnatal HFHS diet), and HH (maternal/postnatal HFHS diet). A fifth group (HRH) received a maternal HFHS diet plus maternal resveratrol treatment and a postnatal chow diet to study the effects of maternal resveratrol therapy.

Results

Maternal resveratrol treatment lessened the weight and adiposity of progeny that were programmed by combined prenatal and postnatal HFHS diets. Maternal resveratrol therapy ameliorated the decreased abundance of the sirtuin 1 (SIRT1) enzyme in retroperitoneal tissue and the altered leptin/soluble leptin receptor ratio of progeny. Maternal resveratrol therapy also decreased lipogenesis and increased lipolysis for progeny.

Conclusions

Maternal resveratrol intervention can prevent adiposity programmed by maternal and postnatal HFHS diets by inducing lipid metabolic modulation. This study offers a novel reprogramming role for the effect of maternal resveratrol supplements against obesity.
Enhanced oral delivery of insulin via the colon-targeted nanocomposite system of organoclay/glycol chitosan/Eudragit®S100

Published: July 2020

This study aimed to develop a ternary nanocomposite system of organoclay, glycol-chitosan, and Eudragit®S100 as an effective colon targeted drug delivery carrier to enhance the oral absorption of insulin. A nanocomplex of insulin and aminoclay was prepared via spontaneous co-assembly, which was then coated with glycol-chitosan and Eudragit S®100 (EGAC-Ins). The double coated nanocomplex, EGAC-Ins demonstrated a high entrapment efficiency of greater than 90% and a pH-dependent drug release. The conformational stability of insulin entrapped in EGAC-Ins was effectively maintained in the presence of proteolytic enzymes. When compared to a free insulin solution, EGAC-Ins enhanced drug permeability by approximately sevenfold in Caco-2 cells and enhanced colonic drug absorption in rats. Accordingly, oral EGAC-Ins significantly reduced blood glucose levels in diabetic rats while the hypoglycemic effect of an oral insulin solution was negligible. In conclusion, EGAC-Ins should be a promising colonic delivery system for improving the oral absorption of insulin.
Proteomic investigation of protein adsorption to cerebral microdialysis membranes in surgically treated intracerebral hemorrhage patients - a pilot study
Authors: Tobieson Lovisa , Czifra Zita , Wåhlén Karin , Marklund Niklas , Ghafouri Bijar
Published: July 2020

Background

Cerebral microdialysis (CMD) is a minimally invasive technique for sampling the interstitial fluid in human brain tissue. CMD allows monitoring the metabolic state of tissue, as well as sampling macromolecules such as proteins and peptides. Recovery of proteins or peptides can be hampered by their adsorption to the CMD membrane as has been previously shown in-vitro, however, protein adsorption to CMD membranes has not been characterized following implantation in human brain tissue.

Methods

In this paper, we describe the pattern of proteins adsorbed to CMD membranes compared to that of the microdialysate and of cerebrospinal fluid (CSF). We retrieved CMD membranes from three surgically treated intracerebral hemorrhage (ICH) patients, and analyzed protein adsorption to the membranes using two-dimensional gel electrophoresis (2-DE) in combination with nano-liquid mass spectrometry. We compared the proteome profile of three compartments; the CMD membrane, the microdialysate and ventricular CSF collected at time of CMD removal.

Results

We found unique protein patterns in the molecular weight range of 10–35 kDa for each of the three compartments.

Conclusion

This study highlights the importance of analyzing the membranes in addition to the microdialysate when using CMD to sample proteins for biomarker investigation.

Published: July 2020

Background

Few data on motivations for using new psychoactive substances (NPS) are available. However, the cost, the legal status, and their accessibility through channels like internet contributed to the popularity of NPS. The objective of this article are first to gain a deeper understanding of the culture surrounding NPS in Belgium and second to define the awareness of the users concerning the content of the NPS they are consuming.

Methods

Snowball sampling and partners in the drug demand reduction field were used as a gateway in order to reach a heterogeneous study population. In total, 45 users were recruited and in-depth interviews were conducted. The personal experiences of NPS users and their needs for support along the continuum of care were explored through an interview guideline, while subjects were given the opportunity to deposit a NPS sample for forensic analysis in a recognized laboratory.

Results

A diversity of profiles was found among NPS users but also a wide diversity in the motives to consume NPS: personal reasons such as pleasure, mind exploration, being connected to others, or out of curiosity, but also external reasons such as price, accessibility or the specific effects procured by certain NPS. The results showed as well that a majority of NPS users seem to be aware of the substances they are using.

Conclusion

Understanding the motivations of use is of importance to determine which type of NPS targeted interventions are adapted to different profiles of users.
Health-related quality of life using specific and generic questionnaires in Spanish coeliac children
Authors: Barrio Josefa , Cilleruelo Maria Luz , Román Enriqueta , Fernández Cristina
Published: July 2020

Background

We aimed to compare the perception of health-related quality of life (HRQOL) and related factors in Spanish coeliac children and their parents, using two questionnaires, the generic KIDSCREEN-52 and the specific the Celiac Disease DUX (CDDUX), and to assess the correlation between them.

Methods

Coeliac children, aged 8-18, who are members of the Madrid Coeliac Association (MCA) and their parents, answered the Spanish version of the CDDUX and KIDSCREEN-52 questionnaires via e-mail. CDDUX was answered by 266 children and 428 parents and KIDSCREEN-52 by 255 children and 387 parents. Linear regression models were fitted to evaluate the association of demographic and clinical factors with HRQOL scores. CDDUX scores were compared with the subjective perception of health status assessed by the first question of KIDSCREEN-52. The correlation between the questionnaires was analysed.

Results

We found that the main factors that negatively affected HRQOL were having social or economic difficulties associated with following the diet and having transgression-related symptoms. The maximum correlation between the questionnaires was 0.309 and − 0.254 in parents and children respectively.

Conclusions

Although there is a poor correlation between the two questionnaires, both agreed that the main concerns of the respondents were related to the social and economic difficulties of following the diet. It would be interesting to use both types of questionnaires in order to perform a more complete assessment of HRQOL in coeliac children.

Background

Neoplastic spinal cord compression is a cause of severe disability in cancer patients. To prevent irreversible paraplegia, a structured strategy is required to address the various impairments present in cancer patients. In this study, we aimed to identify the status where rehabilitation with minimally invasive spine stabilization (MISt) effectively improves ADL.

Methods

We retrospectively reviewed 27 consecutive patients with neoplastic spinal compression who were treated with MISt. We classified the impairments of patients through our multidisciplinary tumor board based on spine-specific factors, skeletal instability, and tumor growth. The neurological deficits, progress of pathological fracture, incidence of vertebral collapse, and postoperative implant failure were examined. Changes of the Barthel index (BI) scores before and after surgery were investigated throughout the clinical courses.

Results

The average duration to ambulation was 7.19 ± 11 days, and we observed no collapse or progression of paralysis except in four cases of complete motor paraplegia before the surgery. Neurological deficiency was improved to or maintained at Frankel’s grade E in 16 patients, remained unchanged in 6 patients (in grades B, C, D), and worsened in 5 patients. BI score comparisons before and after surgery in all patients showed statistically significant increments (p < 0.05). On further analysis, we noted good functional prognosis in patients capable of ambulation within 7 days (p < 0.05) and in patients who could survive longer than 3 months after the surgery (p < 0.05).

Conclusions

In various cancer patients with neoplastic spinal cord compression, skeletal instability as the primary impairment is a good indication for MISt, as the patients showed early ambulation with improved BI scores.

Background

The few health behavior interventions commencing in infancy have shown promising effects. Greater insight into their longer-term benefits is required. This study aimed to assess post-intervention effects of the Melbourne INFANT Program to child age 5y on diet, movement and adiposity.

Methods

Two and 3.5y post-intervention follow-up (2011–13; analyses completed 2019) of participants retained in the Melbourne INFANT Program at its conclusion (child age ~ 19 m; 2008–10) was conducted. The Melbourne INFANT Program is a 15-month, six session program delivered within first-time parent groups in Melbourne, Australia, between child age 4-19 m. It involves strategies to help parents promote healthy diet, physical activity and reduced sedentary behavior in their infants. No intervention was delivered during the follow-up period reported in this paper. At all time points height, weight and waist circumference were measured by researchers, children wore Actigraph and activPAL accelerometers for 8-days, mothers reported children’s television viewing and use of health services. Children’s dietary intake was reported by mothers in three unscheduled telephone-administered 24-h recalls.

Results

Of those retained at program conclusion (child age 18 m, n = 480; 89%), 361 families (75% retention) participated in the first follow-up (2y post-intervention; age 3.6y) and 337 (70% retention) in the second follow-up (3.5y post-intervention; age 5y). At 3.6y children in the intervention group had higher fruit (adjusted mean difference [MD] = 25.34 g; CI95:1.68,48.99), vegetable (MD = 19.41; CI95:3.15,35.67) and water intake (MD = 113.33; CI95:40.42,186.25), than controls. At 5y they consumed less non-core drinks (MD = -27.60; CI95:-54.58,-0.62). Sweet snack intake was lower for intervention children at both 3.6y (MD = -5.70; CI95:-9.75,-1.65) and 5y (MD = -6.84; CI95:-12.47,-1.21). Intervention group children viewed approximately 10 min/day less television than controls at both follow-ups, although the confidence intervals spanned zero (MD = -9.63; CI95:-30.79,11.53; MD = -11.34; CI95:-25.02,2.34, respectively). There was no evidence for effect on zBMI, waist circumference z-score or physical activity.

Conclusions

The impact of this low-dose intervention delivered during infancy was still evident up to school commencement age for several targeted health behaviors but not adiposity. Some of these effects were only observed after the conclusion of the intervention, demonstrating the importance of long-term follow-up of interventions delivered during early childhood.
