AbstractObesity is a global health concern because of its increasing trend both in developed and developing countries. A limited number of studies have evaluated the association of liver enzymes with both general and abdominal obesity in the general population; data for the Bangladeshi population are not available yet. This study aimed to assess the relationship of serum liver enzymes activity with both general and abdominal obesity in Bangladeshi adults. In total, 540 blood samples were obtained from the participants (388 males and 152 females) and analyzed for serum levels of ALT, AST, GGT, and ALP using standard methods. General obesity was defined as body mass index (BMI) ≥ 27.5 kg/m2 and abdominal obesity was defined as waist circumference (WC) ≥ 90 cm in males and ≥ 80 cm in females. The relationship between liver enzymes and obesity was evaluated by multivariate logistic regression models. Overall, 58% of participants in the general obesity group and 55% of the participants in the abdominal obesity group had at least one or more elevated levels of liver enzymes. The prevalence of elevated liver enzymes was significantly higher in the obesity group compared to the normal BMI and WC groups (p < 0.05 for all cases). The mean level of serum ALT, AST and GGT were significantly higher in the obesity group than the normal BMI group (p < 0.05). In the WC groups, mean AST and GGT were significantly higher in the obesity group compared to the normal group (p < 0.05). In regression analysis, serum levels of ALT showed an independent and significant association with general obesity, whereas, serum GGT showed a significant association with both general and abdominal obesity. In conclusion, a high prevalence of elevated liver enzymes was observed among participants included in the present study. Of the four enzymes, serum GGT was independently associated with both general and abdominal obesity. Further studies are required to understand the complex relationship between liver enzymes and obesity in the general population.

Abstract The aim of this project was to evaluate the relationship of matrix metalloproteinase-9 (MMP-9) genetic variation and its serum concentration with autism spectrum disorder (ASD). One hundred ASD and 120 controls were enrolled in this study. Genomic DNA was extracted from blood and MMP-9 polymorphism was determined by polymerase chain reaction restriction fragment length polymorphism and serum levels were measured by enzyme-linked immunosorbent assay. The frequencies of CC, CT, and TT genotypes were 72%, 26%, and 2% in controls and 31%, 57%, and 12% in ASD, respectively. The frequencies of C and T alleles in ASD were 59.5% and 40.5%, and controls were 86% and 14%, respectively. There is a significant increase in serum MMP-9 levels in ASD as compared to controls. We have also shown that TT genotype is significantly associated with increase serum MMP-9 levels in patients (TT, CT, and CC serum levels were 91.77 ± 10.53, 70.66 ± 7.21, and 38.66 ± 5.52 and in controls were 55.55 ± 11.39, 42.66 ± 7.85, and 30.55 ± 6.34 ng/ml, respectively). It is concluded that there is a significant association between rs3918242 MMP-9 polymorphism and its serum concentration with autism. We also suggest that TT genotype is associated with increased MMP9 expression and may be a risk factor for ASD.

Abstract Objectives 1. Determine acceptability and feasibility of a phototherapy kiosk designed as a self-care intervention for low vitamin D; 2. Demonstrate that narrow spectrum ultraviolet (UV) B delivered by the kiosk is equivalent to recommended daily D3 supplementation to raise or maintain serum 25-hydroxyvitamin (OH)D levels at or above 30 ng/mL; and 3. Examine the relationship of demographic variables, including age, gender, body mass index, physical activity, ethnicity, skin type, season, and sun exposure to serum 25(OH)D levels in both treatment arms. Methods Participants were randomized to either the phototherapy kiosk (PK) for a treatment every other week or 600 IU D3 oral supplement (OS) daily, for 10 weeks. PK exposure was based on response to previous treatment and Fitzpatrick Skin Type category; subjects wore undergarments only and eye protection for treatments of 2–6 minutes duration. OS group received a one-time prescription of 70 capsules, dispensed by a research pharmacist. Primary outcome was serum 25(OH)D level. Results Final sample 88 adults; OS group n = 45 and PK group n = 43. Demographics: median age 35 years, mostly female (66%), no difference observed between groups for age, race/ethnicity, or marital status. No difference seen in skin type, birth location, sun exposure, or use of sunscreen. OS group had higher BMI and %body fat. Baseline 25(OH)D level were similar, P = 0.25. At 12 weeks median OS 25(OH)D 25.5 ng/mL and PK 30 ng/mL; P = .01. At 16 weeks, OS group 25(OH)D level 21 ng/mL and PK 27 ng/mL; P = .04. Adherence: OS 92% vs PK 100%. There were no reportable adverse events. Conclusions Use of PK every other week achieved higher serum levels of 25(OH)D than usual care vitamin D3 600 IU/day for 10 weeks, although both groups returned to baseline levels 30 days post-treatment. At a time when self-care measures are highly valued for health promotion, programmed UVB delivered via PK in the community appears to be a safe, efficacious alternative to oral D3 supplementation but requires recurring use. Results from this study suggest a need for early intervention in preventable health conditions impacting Warfighter performance and readiness, particularly pre-deployment when optimizing long-term wellness for duty in austere environments.

Abstract We studied the effect of serum folate-binding protein (FBP) on folate radioassays and the relationship of the serum level of unsaturated FBP to the serum folate level in various clinical states. Our modification of a heat-extracted radioassay was compared to a whole serum radioassay. Our results confirmed the existence of elevated serum levels of unsaturated FBP in some normal subjects, in some women taking oral contraceptives, and in most patients with uremia. Elevated levels of unsaturated FBP will produce falsely low results in folate radioassay unless the FBP has been destroyed by heat, as was done in the modified radioassay here presented. In normal and uremic subjects, serum folate and unsaturated FBP levels tended to correlate, whereas in patients taking large doses of folic acid the level of unsaturated FBP fell as the level of serum folate rose.
