Effects of Aerobic Exercises on Serum Levels of Myonectin and Insulin Resistance in Obese and Overweight Women

Background and Aim: Obesity is associated with cardiovascular diseases, metabolic syndrome, and diabetes and insulin resistance. Myonectin is a myokine mostly secreted from skeletal muscles and inversely associated with obesity. The aim of the present study was to evaluate the effects of 8 weeks of aerobic exercises on serum levels of myonectin and insulin resistance in obese and overweight women. Materials and Methods: Eighty obese women were assigned to exercise (34) and control groups (46). The exercise program comprised three weekly 45-minute sessions of aerobic exercise training for 8 weeks that included running with 50–70% of maximum heart rate (first 2 weeks – 50%; second week – 60%; third week – 65%; and the last 2 weeks by 70% of maximum heart rate). Twenty-four hours before and after the training session, fasting myonectin serum levels were measured. ANCOVA was used to assess differences between the groups. Results: Serum levels of myonectin in the experimental group increased significantly (P=0.000); however, insulin resistance significantly decreased in the experimental group (P=0.000). Conclusion: Therefore, considering the role of myonectin in increasing fatty acid uptake, exercise training can play an essential role in decreasing obesity-related diseases and metabolic syndrome; this effect is partly related to the roles of myonectin. Therefore, the use of this type of exercise is recommended to reduce the risk of diseases associated with obesity and metabolic syndrome.
Passenger Lymphocyte Syndrome After Pediatric Liver Transplantation.

BACKGROUND Passenger lymphocyte syndrome (PLS) is a less known etiology of acute onset anemia following ABO-compatible (ABO-c) liver transplantation (LT). Available literature on PLS after pediatric LT is limited. Therefore, we evaluated the prevalence, clinical course, and risk factors of PLS in children following ABO-c LT. METHODS A single-center retrospective review of all children who underwent LT between 2000 and 2017 was performed. PLS was defined as a drop-in hemoglobin >20 g/L within 30 days of LT, with positive direct antiglobulin test and 1 laboratory test confirming hemolysis. Chi square and student t tests compared variables between subjects with and without PLS. RESULTS Amongst 333 pediatric LT performed, 51 children received an ABO-c graft. PLS was diagnosed in 7 (14%) subjects at a median of 10 days after LT. There were no significant differences in patient demographics, graft type, or immunosuppression between those who did and did not develop PLS. Recipient blood group A+ receiving a donor O+ graft was a risk factor for PLS (P = 0.015). All PLS subjects recovered with blood transfusions (median 2), and no additional interventions. Three subjects initially received recipient (instead of donor) blood group red cells. CONCLUSIONS We report a 14% prevalence of PLS following pediatric ABO-c LT. Recipient blood group A+ receiving a donor O+ graft is a risk factor for PLS. Recognition of PLS as a cause of early acute anemia in pediatric ABO-c LT enables timely transfusion with donor (rather than recipient) blood group red cells.
Single center evidence for the treatment of basal cell carcinoma of the head and neck

Aim: Basal Cell Carcinoma (BCC) alone accounts for 80% of cases of non-melanoma skin cancer (NMSC), which characteristically develops on sun-exposed skin. Indeed the most common site of BCC is the head and neck region (80%). The purpose of this study to review the experience of our center with BCC in the head and neck region to report the sites of occurrence and treatment. Materials and method: We retrospectively reviewed 77 patients with BCC of the head and neck, who revived surgical treatment within our plastic surgery division. Basic demographic data, cancer site and size, surgical treatment and histological data were collected. The mean follow-up period was 12 months. Results: The study population included 37 males and 40 females, with a mean age of 74.12 years. The nasal unit was the main site of BCC (31.82%), followed by the periorbital (13.64%) and cervical (12.5%) units. Primary closure was the main surgical procedure performed (72.5%), followed by local flap (26.1%) and full-thickness skin grafts (1.4%). The safety resection margin ranged from 4.5 to 9 mm, with a 98.7% complete removal rate. Neither recurrence nor any newly-developed lesions were reported during follow-up in any patient. Discussion: Our work reflects the shift in the incidence of BCC, which now seems to be more frequent in females. Furthermore, our data strengthens the association between UVR exposure and BCC, confirms its predilection to occur on the nasal unit and validates surgical excision as the gold standard treatment for skin cancer.

Epidemiology, toxicokinetics and biomarkers after self-poisoning with Gloriosa superba

Abstract Introduction: Gloriosa superba is a flowering plant that contains colchicine. Deliberate self-poisoning with this plant in Sri Lanka is common and potentially fatal. The objective of this study was to describe the epidemiology, toxicokinetics and selected biomarkers in these patients. Materials and methods: The study consisted of three parts; epidemiologic and outcome data (n = 297), concentrations and toxicokinetics (n = 72), evaluation of urinary and serum biomarkers (n = 45). Plasma colchicine levels were measured by high-performance liquid chromatography (HPLC). We also measured serum biomarkers: creatinine (sCr), cystatin C (sCysC) and creatine kinase (CK), and urinary biomarkers: creatinine, kidney injury molecule-1 (KIM – 1), clusterin, albumin, beta-2-microglobulin (β2M), cystatin C, neutrophil gelatinase-associated lipocalin (NGAL), osteopontin (OPN) and trefoil factor 3 (TFF3). Results: The case fatality was 10% (29/297), and death was much more common in older patients. Median concentrations of colchicine were higher in those over 65 [median 4.7 ng/mL (IQR: 1.7–6.6) vs. 1.2 (IQR: 0.2–2.7) for those <35]. Admission colchicine concentrations were highly correlated with a fatal outcome [median 7.8 ng/ml (IQR: 5.8–18.7) vs 1.2 (0–2.3) in survivors]. The area under the receiver operating characteristic curve (AUC-ROC) for uncorrected admission colchicine level was highly predictive of a fatal outcome, and this improved even further with two methods we developed to correct for the expected change with time. The best method had an AUC-ROC of 0.98 (95%CI 0.94–1.00) in predicting death, with 100% sensitivity and 96% specificity at the best cut-point. Discussion: Fatal outcomes and high concentrations were both much more common in the elderly following poisoning with Gloriosa superba. Our findings are consistent with kinetic data after medicinal colchicine ingestion. Conclusions: Gloriosa superba self-poisoning causes significant mortality. High concentration of colchicine is highly predictive of a fatal outcome. Ingestion of Gloriosa superba caused only mild acute kidney injury (AKI) and rhabdomyolysis.
Xyloglucan + Gelose Combination versus Placebo as Adjuvant Therapy to First-Line Antimicrobials for Uncomplicated Urinary Tract Infection in Adults

Background: A medical device containing xyloglucan-gelose-hibiscus-propolis (referred to hereafter as xyloglucan + gelose) acts as a mucosal barrier protector and urinary acidifier. The safety and efficacy of this device were investigated as adjuvant therapy to first-line antimicrobials for treatment of uncomplicated urinary tract infection (UTI) in adults. Patients and Methods: In this multicentre, randomised, parallel group, double-blind, phase IV study, xyloglucan + gelose (n = 20) or placebo (n = 20) were administered orally in combination with an antimicrobial agent (e.g., ciprofloxacin) for 5 days, then alone for 5 days, then beginning on Day 30 of the study for 15 days per month for 2 months. Results: Frequency of adverse events (AEs) was 5 and 45% in the xyloglucan + gelose and placebo groups respectively. All AEs were unrelated to study products. Xyloglucan + gelose reduced uroculture positivity (defined as a bacterial count ≥103 CFU/mL) from 100% of patients at baseline to 0% at Day 11, with recurrence in 3 patients (15%) by Day 76. Corresponding results with placebo were 100% uroculture positive patients at baseline reduced to 45% at Day 11, with recurrence in 14 patients (70%) by Day 76. Xyloglucan + gelose significantly reduced the frequency of urinary incontinence and urgency of micturition compared with placebo (both p < 0.05), with symptom resolution in all patients by Day 90. Conclusions: The xyloglucan + gelose medical device was safe, well tolerated, and it reduced bacteriological and symptomatic parameters in adults with uncomplicated UTI.
The Prognostic Value of Baseline 18F-FDG PET/CT in Human Papillomavirus–Positive Versus Human Papillomavirus–Negative Patients With Oropharyngeal Cancer

Purpose Oropharynx cancer (OPC) is heterogeneous; human papillomavirus (HPV)–positive and HPV− tumors represent 2 disease entities with a different prognosis. Earlier studies investigating the prognostic value of pretreatment 18F-FDG PET in OPC are small or included patients with unknown HPV status. This study assessed the prognostic value of PET variables, in a large cohort with balanced HPV status. Methods Retrospectively, primary tumor SUVmax, SUVpeak, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were extracted from baseline FDG PET/CT of patients with OPC treated with (chemo)radiation. The Pearson correlation between the PET variables was calculated. With linear regression, the correlation between the PET variables and HPV status, age, smoking status, T stage, N stage, and American Joint Committee on Cancer stage was calculated. Univariable and multivariable Cox models analyzed local control, overall survival, and disease-free survival (DFS). Results Of 201 patients, 109 were HPV+. Metabolic tumor volume and TLG correlated (r = 0.96), as did SUVpeak and SUVmax (r = 0.97). The PET variables correlated strongest with HPV status and T stage. These two accounted for 40% of the variance of MTV and 33% of TLG. Human papillomavirus–negative tumors had a significantly higher SUVmax, SUVpeak, MTV, and TLG. In univariable analysis, all PET variables were significantly associated with local control, overall survival, and DFS. In multivariable analysis, TLG was significantly associated to DFS in patients with HPV− OPC (hazard ratio, 1.005; 95% confidence interval, 1.001–1.010; P = 0.03). However, we did not observe this in HPV+ patients. Conclusions Increased baseline TLG is associated with worse DFS in HPV− OPC and might be used as biomarker for risk stratification in these patients. Interestingly, we could not identify this association in HPV+ patients.
Hemostatic profile in patients with and without postpartum hemorrhage

Background The association between coagulation profile and postpartum hemorrhage (PH) is still debated. Objective To determine the association between hemostatic profile and PH in women with cesarean operation (CO). Methods We included 92 patients with PH (cases) and 184 without (controls), patients were attended during 2014, at one hospital of the Instituto Mexicano del Seguro Social in Mérida, Yucatán. Demographic, clinical and laboratory data including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count (PLC), and fibrinogen concentration were compared among cases and controls using a binary logistic regression model (LRM), from which odd ratios (OR), and 95% confidence intervals (95% CI), were obtained. Results According to the bivariate comparison, in the LRM categorical data such as parity, any type of hypertensive comorbidity, type of anesthesia, and categorized aPTT (< 38 vs. ≥ 38 seconds), and one continuous variable (gestational age) were included. Having some hypertensive comorbidity (OR 3.55, 95% CI: 1.95-6.47), type of anesthesia (regional anesthesia, OR 0.27, 95% CI: 0.13-0.55) and aPTT (< 38 seconds, OR 0.26, 95% CI: 0.10-0.66) were all statistically significant. Categorized PT, platelet count and fibrinogen concentration, were not statistically significant. Conclusions In this sample, having some hypertensive comorbidity increased risk of PH more than three times, while regional anesthesia and aPTT < 38 seconds reduced risk in 73% and 74%, respectively. Neither platelet count, nor fibrinogen concentration, or the PT categories modified risk of PH.
Staged procedure protocol based on the four-column concept in the treatment of AO/OTA type 43-C3.3 pilon fractures

Objective We herein introduce a staged management protocol for AO/OTA type 43-C3.3 pilon fractures based on the four-column theory designed to protect the soft tissue. Methods Twenty-three patients with 25 type C3.3 pilon fractures underwent a staged procedure with four-column osteosynthesis from April 2014 to December 2016. The first stage involved immediate calcaneal traction or external fixation to span the ankle joint. When the soft tissue swelling decreased, the posterolateral approach was used to restore the lateral column and initially fix the posterior column. After 10 to 12 days, the third stage involved treatment of the anterior and medial columns through the anterior approach. Charts and radiographs were reviewed, and the American Orthopaedic Foot and Ankle Society (AOFAS) evaluation system was used to evaluate the postoperative outcomes. Results All fractures achieved union after a mean of 3.3 months (range, 2.0–5.7 months) after the third stage. A good or acceptable reduction rate was observed in 85.7% of the patients. Results from the AOFAS evaluation system indicated excellent or good postoperative ankle function in 81.0% of the patients. Conclusion This staged procedure protocol combined with the four-column theory is a feasible way to protect the soft tissue and reduce the fracture.
Knowledge, Attitude and Practice about Dengue Fever among Patients Experiencing the 2017 Outbreak in Vietnam

There is a gap in the literature on the understanding of the general Vietnamese population toward dengue fever (DF). This study aimed to explore knowledge, attitudes, practice (KAP) of dengue fever among Vietnamese participants and the potential associated factors. A cross-sectional study was conducted among 330 patients at the Bach Mai Hospital in Northern Vietnam. A Tobit regression model was utilized to investigate the associated factors. The average knowledge score was 4.6/19. Respondents perceived their risk of DF infection to be very low (39.5%) to low (20.7%) and had a neutral attitude about the necessity of hospitalization when being infected with DF (60.9%). A total of 17.6%, 9.8% and 6.6% of respondents reported frequently changing water, properly disposing of waste and covering water storage containers to eliminate larvae. Gender, education level, duration of illness and travel history were correlated with knowledge. Occupation, the presence of DF in the neighborhood, mosquito density at home and DF symptom severity were associated with attitudes. Occupation, mosquito density at home, type of patient, knowledge and attitudes were associated with practices. To enhance the KAP towards DF, further efforts should first be directed to improve knowledge through education, especially at the school level and people in less developed areas.
Exosomal transfer of bone marrow mesenchymal stem cell-derived miR-340 attenuates endometrial fibrosis

ABSTRACT Bone marrow mesenchymal stem cells (BMSCs) have potential therapeutic benefits for the treatment of endometrial diseases and injury. BMSCs interact with uterus parenchymal cells by direct contact or indirect secretion of growth factors to promote functional recovery. In this study, we found that BMSC treatment in rats subjected to mechanical damage (MD) significantly increased microRNA-340 (miR-340) levels in the regenerated endometrium. Then we employed knockin and knockdown technologies to upregulate or downregulate the miR-340 level in BMSCs (miR-340+ BMSCs or miR-340− BMSCs) and their corresponding exosomes, respectively, to test whether exosomes from BMSCs mediate miR-340 transfer. We found that the exosomes released from the primitive BMSCs or miR-340+ BMSCs but not miR-340− BMSCs increased the miR-340 levels in primary cultured endometrial stromal cells (ESCs) compared with control. Further verification of this exosome-mediated intercellular communication was performed using exosomal inhibitor GW4869. Tagging exosomes with red fluorescent protein demonstrated that exosomes were released from BMSCs and transferred to adjacent ESCs. Compared with controls, rats receiving primitive BMSC treatment significantly improved functional recovery and downregulated collagen 1α1, α-SMA and transforming growth factor (TGF)-β1 at day 14 after MD. The outcomes were significantly enhanced by miR-340+ BMSC treatment, and were significantly weakened by miR-340− BMSC treatment, compared with primitive BMSC treatment. In vitro studies reveal that miR-340 transferred from BMSCs suppresses the upregulated expression of fibrotic genes in ESCs induced by TGF-β1. These data suggest that the effective antifibrotic function of BMSCs is able to transfer miR-340 to ESCs by exosomes, and that enhancing the transfer of BMSC-derived miR-340 is an alternative modality in preventing intrauterine adhesion. Summary: miR-340 in the exosomes released from BMSCs are transferred to endometrial cells, which regulate gene expression, repress endometrial fibrosis and promote functional recovery in rats subjected to mechanical damage.
Accelerated Summer Weight Gain in a Low-Income, Ethnically Diverse Sample of Elementary School Children in Massachusetts.

Background: Several studies have found that children in the United States gain weight at a faster rate in the summer than in the school year, but little is known about the prevalence of this problem, its effect on high-risk subgroups, or its determinants. This study compares school year and summer weight change in a low-income, ethnically diverse sample of school-age children in Massachusetts and explores differences by race/ethnicity, weight status, and exposure to school year physical activity (PA) programming. Diet and PA are examined as potential mediators of summer weight gain. Methods: Children participating in a school-based PA program evaluation (in which weight change was not a primary outcome) had their height and weight measured three times between October 2015 and September 2016 to capture a school year and summer interval. Diet and PA patterns were assessed mid-school year and mid-summer in a subsample of children. Mixed linear models were used to estimate the effect of season (school year vs. summer) on change in BMI and to examine the influence of race/ethnicity, weight status, and program (walk/run, classroom activity breaks, or control) on any observed effects. Structural equation models were used to explore diet and PA as mediators of seasonal weight change in a subsample of participants. Results: Of 769 participants, 53% were non-Caucasian, 40% were overweight or obese, and 58% were eligible for free or reduced-price school meals. BMI increased in both the school year and summer but increased more rapidly in the summer (0.046 kg/m2 more per month, p = 0.007). Of the three tested interactions, statistical significance was only observed between season and program (χ2 = 14.90, p < 0.001); on average, children exposed to a school year walk/run program did not gain weight more rapidly during the summer, whereas children in the control group and a classroom activity breaks program did. Poorer diet and PA patterns were observed in the summer, but neither diet nor PA was statistically significant mediators of BMI change. Conclusions: Children in this high-risk sample gained weight at a faster rate during the summer than during the school year, with no discernable demographic differences. However, this phenomenon was not observed in the subgroup exposed to a school year walk/run program. More research is needed to clarify the determinants of summer weight gain and understand how school year programming and its effects can be transferred to the summer months.
Prevalence and correlations of hepatorenal functions in diabetes and cardiovascular disease among stratified adults

Background: The vulnerability of older adults to diabetes and cardiovascular complications is a global concern. Hepatorenal pathophysiology is implicated in these complications, but has yet to be clearly established, especially from rural low-mid income countries. This study investigates differences in prevalence of diabetes in aging groups and correlations of age with hepatorenal variables. Methods: 203 participants of both sexes above the age of 18 years underwent anthropometric measurements at Catholic Hospital, Abbi, Nigeria. Questionnaires collected demographic information and medical history. Urinalysis as well as routine liver and renal function tests were performed. Data analysis included determination of levels of hepatorenal abnormalities and prevalence of diseases in age groups. Percentage of disease subpopulations made up by each age-group was also determined as well as Pearson’s correlation coefficient between age and hepatorenal variables, and comparison of average age and hepatorenal variables in disease subgroups. Results: Percentage hepatorenal abnormalities are not significantly different between age-groups. There is no significant difference in percentage level of disease between groups, but in age-groups constituting disease sub-populations (p<0.00001). The apparently healthy subpopulation comprises of younger adults compared to older adults constituting diabetes and hypertension (p < 0.). Age shows moderate correlation with renal function parameters, especially urea and chloride (r = 0.42), but relatively insignificant with liver function variables. Conclusion: This report affirms that diabetes cardiovascular co-morbidity comes with aging. It also indicates that renal pathophysiology may be more associated, than liver, functions in the vulnerability of adults. (www.actabiomedica.it)
Matrix Metalloproteinases in Pulmonary and Central Nervous System Tuberculosis—A Review

Tuberculosis (TB) remains the single biggest infectious cause of death globally, claiming almost two million lives and causing disease in over 10 million individuals annually. Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes with various physiological roles implicated as key factors contributing to the spread of TB. They are involved in the breakdown of lung extracellular matrix and the consequent release of Mycobacterium tuberculosis bacilli into the airways. Evidence demonstrates that MMPs also play a role in central nervous system (CNS) tuberculosis, as they contribute to the breakdown of the blood brain barrier and are associated with poor outcome in adults with tuberculous meningitis (TBM). However, in pediatric TBM, data indicate that MMPs may play a role in both pathology and recovery of the developing brain. MMPs also have a significant role in HIV-TB-associated immune reconstitution inflammatory syndrome in the lungs and the brain, and their modulation offers potential novel therapeutic avenues. This is a review of recent research on MMPs in pulmonary and CNS TB in adults and children and in the context of co-infection with HIV. We summarize different methods of MMP investigation and discuss the translational implications of MMP inhibition to reduce immunopathology.
