Higher dietary diversity score is associated with obesity: a case-control study.

OBJECTIVE: The present study was carried out to compare dietary diversity score (DDS) among overweight, obese, and normal-weight adults. STUDY DESIGN: This case-control study was conducted with a total of 200 cases (100 participants with obesity and 100 participants with overweight) and 300 controls (normal weight) matched by socio-economic status (SES), older than 18 years. METHODS: Dietary intakes were assessed using a self-administered Food Frequency Questionnaire. Data regarding physical activity and sociodemographic variables were gathered. DDS was computed based on the scoring of the five food groups emphasized in the United States Department of Agriculture Food Guide Pyramid. Anthropometric measurements were measured, and the body mass index and waist-to-hip ratio were calculated. RESULTS: The mean ± standard deviation of DDS was higher in participants with obesity (5.65 ± 1.32) than that in overweight participants (5.23 ± 1.23), while the lowest score was reported among normal-weight individuals (4.97 ± 1.42) (P < 0.001). The odds of obesity increased with each unit increase in DDS (odds ratio [OR]: 1.46; 95% confidence interval [CI]: 1.22, 1.74). However, the association became slightly weaker after adjusting for potential confounding factors (OR: 1.34; 95% CI: 1.07, 1.68). CONCLUSION: It was concluded that there was a significant positive association between DDS and obesity. However, additional investigations are warranted.

Polo-like kinase 1 inhibition results in misaligned chromosomes and aberrant spindles in porcine oocytes during the first meiotic division.

Polo-like kinase 1 (Plk1), a type of serine/threonine protein kinase, has been implicated in various functions in the regulation of mitotic processes. However, these kinase's roles in meiotic division are not fully understood, particularly in the meiotic maturation of porcine oocytes. In this study, the expression and spatiotemporal localization of Plk1 were initially assessed in the meiotic process of pig oocytes by utilizing Western blotting with immunofluorescent staining combined with confocal microscopy imaging technique. The results showed that Plk1 was expressed and exhibited a dynamic subcellular localization throughout the meiotic process. After germinal vesicle breakdown (GVBD), Plk1 was detected prominently around the condensed chromosomes and subsequently exhibited a similar subcellular localization to α-tubulin throughout subsequent meiotic phases, with particular enrichment being observed near spindle poles at MI and MII. Inhibition of Plk1 via a highly selective inhibitor, GSK461364, led to the failure of first polar body extrusion in porcine oocytes, with the majority of the treated oocytes being arrested in GVBD. Further subcellular structure examination results indicated that Plk1 inhibition caused the great majority of oocytes with spindle abnormalities and chromosome misalignment during the first meiotic division. The results of this study illustrate that Plk1 is critical for the first meiotic division in porcine oocytes through its influence on spindle organization and chromosome alignment, which further affects the ensuing meiotic cell cycle progression.

The effect of hydroxyzine on treating bruxism of 2- to 14-year-old children admitted to the clinic of Bandar Abbas Children Hospital in 2013-2014.

Introduction. Bruxism is to press or grind teeth against each other in non-physiologic cases, when an individual does not swallow or chew. If not treated, teeth problems, stress, mental disorders, frequent night waking, and headache is expected. This research aimed to study the effect of hydroxyzine on treating bruxism of 2- to 14-year-old children admitted to the clinic of Bandar Abbas Children Hospital. Methodology. In this clinical trial, 143 children with the ages between 4-12 years were admitted to the Children Hospital and were divided randomly into test and control groups. The test group consisted of 88 hydroxyzine-treated children and the control group consisted of 55 children who used hot towels. Both groups were examined in some stages including the pre-test stages or the stage before starting treatments at two, four, and six weeks and four months after stopping the treatment. The effects of each treatment on reducing bruxism symptoms were assessed by a questionnaire. The data were analyzed by using SPSS in descriptive statistics, t-test, and ANOVA. Results. As far as bruxism severity was concerned, the results showed a significant difference between the test group members who received hydroxyzine and the control group members who received no medication. T-test results showed a statistically significant difference between the test and the control groups in the second post-test (four weeks later) (p. value ≤ 0.05). Mean of the scores of bruxism severity in the test group has changed significantly in the post-test (at two weeks, four weeks, and six weeks later) as compared to the pre-test. Whereas, as far as the response to the treatment, no significant difference was recorded between the control group and the test group 4 weeks after the treatment. Discussion. The results showed that prescribing hydroxyzine for 4 weeks had a considerable effect in diminishing bruxism severity between the test groups.

Is there any correlation between high sensitive CRP and disease activity in systemic lupus erythematosus?

The role of C-reactive protein (CRP) in systemic lupus erythematosus (SLE) as an inflammatory marker is still controversial. Recently, more sensitive methods, such as high sensitive CRP (hs-CRP) have been used to detect micro-inflammation. The role of hs-CRP in lupus flare has not been documented well. We conducted this study to examine the correlation between hs-CRP serum concentrations and disease activity in lupus. Ninety-two SLE patients and 49 healthy controls contributed to our study. Most confounding factors influencing the hs-CRP values were excluded. Disease activity was estimated using the SLE Disease Activity Index (SLEDAI-2K). hs-CRP values were determined using an enzyme-linked immunosorbent assay (ELISA) kit. Serum values of hs-CRP were significantly higher (p < 0.001, z = 3.29) in patients compared with healthy controls. The cutoff point for hs-CRP between patients and controls was 0.93 mg/L (Youden's Index = 0.39). There was no correlation between hs-CRP serum levels and disease activity. Furthermore, hs-CRP values did not correlate with any of the laboratory parameters, except for C3 (p = 0.003, r(s) = -0.2) and C4 (p = 0.02, r(s) = -0.1). Although hs-CRP serum levels were significantly higher in lupus patients compared with healthy controls, it seems that this marker is not a good indicator for disease activity.

Clinical course and outcome of snake envenomation at a hospital in Karachi.

INTRODUCTION: Snake envenomation is a frequently reported medical emergency at the Civil Hospital Karachi, Pakistan, [corrected] thus obviating the need to assess the patterns of the clinical course and outcome of snake envenomation cases. METHODS: The demographic characteristics, clinical signs and symptoms, laboratory findings, treatment and outcome of 80 victims of snake bite were recorded. These patients were admitted to the Civil Hospital Karachi between January 2006 and September 2007. The data of all the cases was analysed statistically using the Statistical Package for the Social Sciences version 11.0. RESULTS: The majority of the 80 victims of snake bite were male (80 percent) and 20 percent were female. The mean age of the patients was 33.3 years. The main type of envenomation was vasculotoxic (92.5 percent), and none were neurotoxic or myotoxic. Both local and systemic clinical features of envenomation were present. Bleeding was reported in 43.8 percent of the patients. 71.3 percent of the patients showed coagulopathy of defibrination and the anti-coagulant type. All patients received anti-snake venom. Five (6.3 percent) patients in the study died. CONCLUSION: The most common type of snake envenomation in this part of the province of Sindh is vasculotoxic due to the high inhabitancy of Viperidae. High morbidity and mortality rates can be reduced significantly through patient education on the precautions that need to be taken by farmers and field workers against snake bite. Early referral to a well-equipped health facility is necessary, as the mortality rate was high among those patients who arrived late.
