Religious minority identity associates with stress and psychological health among Muslim and Hindu women in Bangladesh and London

OBJECTIVES

This study examined the association of minority religious identification (Hindu or Muslim) with self-reported stress and psychological symptoms among sedentee and immigrant Bangladeshi women.

METHODS

Women, aged 35-59 (n = 531) were drawn from Sylhet, Bangladesh and London, England. Muslim immigrants in London and Hindu sedentees in Sylhet represented minority religious identities. Muslim sedentees in Sylhet and Londoners of European descent represented majority religious identities. In bivariate analyses, minority religious identity was examined in relation to self-reported measures of stress, nervous tension, and depressed mood. Logistic regression was applied to examine the relationship between these variables while adjusting for marital status, parity, daily walking, and perceived financial comfort.

RESULTS

In bivariate analyses, religious minorities reported more stress than religious majorities in all group comparisons (p < .05), and minority Muslims reported more nervous tension and depressed mood than majority Muslims (p < .05). In logistic regression models, minority Muslims had greater odds of high stress than majority Muslims (OR 2.00, 95% CI 1.18-3.39). Minority Muslims had greater odds of stress (OR 3.05, 95% CI 1.51-6.17) and nervous tension (OR 3.37, 95% CI 1.66-6.87) than majority Londoners. Financial comfort reduced odds of stress and symptoms in all models.

CONCLUSIONS

Socioeconomic situation, immigration history, and minority ethnicity appear to influence the relationship between religious identity and psychosomatic symptoms in Bangladeshi women. Attention to personal and socioeconomic context is important for research examining the association between religion and mental health.

Comparison of Decaying Antibody Level After SARS-CoV-2 Infection in Case of Home Treated and Hospital Treated Patients at Different Interval

The aim of the study was to evaluate the quantities difference and persistence of antibody in home and hospital treated patients at different interval. A cross-sectional study was conducted in the Department of Biochemistry and Molecular Biology, BIRDEM General Hospital, from July, 2020 to June, 2021. This study protocol was approved by Institutional Review Board (IRB), BIRDEM. SARS-CoV-2 caused death of huge number of people. The disease most commonly represents with fever, cough, loss of smell sensation, fatigue etc. Who had mild symptoms did not admit at hospital. But when the disease progress to respiratory distress, involvement of lung field more than 50.0% and other complications then the patients need hospital admission. Hospital treated patients showed higher antibody status in comparison to home treated patients. Moreover it was reported that increased amount of antibody developed after 3rd and 4th months of SARS-CoV-2 infection. In this study, statistically significant difference of decaying antibody level between home and hospital treated patients was observed.

Treatment with benznidazole and pentoxifylline regulates microRNA transcriptomic profile in a murine model of Chagas chronic cardiomyopathy

Chronic Chagas cardiomyopathy (CCC) is one of the leading causes of morbidity and mortality due to cardiovascular disorders in endemic areas of Chagas disease (CD), a neglected tropical illness caused by the protozoan parasite Trypanosoma cruzi. CCC is characterized by parasite persistence and inflammatory response in the heart tissue, which occur parallel to microRNA (miRNA) alterations. Here, we investigated the miRNA transcriptome profiling in the cardiac tissue of chronically T. cruzi-infected mice treated with a suboptimal dose of benznidazole (Bz), the immunomodulator pentoxifylline alone (PTX), or the combination of both (Bz+PTX), following the CCC onset. At 150 days post-infection, Bz, PTX, and Bz+PTX treatment regimens improved electrocardiographic alterations, reducing the percentage of mice afflicted by sinus arrhythmia and second-degree atrioventricular block (AVB2) when compared with the vehicle-treated animals. miRNA Transcriptome profiling revealed considerable changes in the differential expression of miRNAs in the Bz and Bz+PTX treatment groups compared with the control (infected, vehicle-treated) group. The latter showed pathways related to organismal abnormalities, cellular development, skeletal muscle development, cardiac enlargement, and fibrosis, likely associated with CCC. Bz-Treated mice exhibited 68 differentially expressed miRNAs related to signaling pathways like cell cycle, cell death and survival, tissue morphology, and connective tissue function. Finally, the Bz+PTX-treated group revealed 58 differentially expressed miRNAs associated with key signaling pathways related to cellular growth and proliferation, tissue development, cardiac fibrosis, damage, and necrosis/cell death. The T. cruzi-induced upregulation of miR-146b-5p, previously shown in acutely infected mice and in vitro T. cruzi-infected cardiomyocytes, was reversed upon Bz and Bz+PTX treatment regimens when further experimentally validated. Our results further our understanding of molecular pathways related to CCC progression and evaluation of treatment response. Moreover, the differentially expressed miRNAs may serve as drug targets, associated molecular therapy, or biomarkers of treatment outcomes.

Role of Transabdominal Ultrasonogram for Evaluation of Placental Maturity in Relation with Fetal Gestational Age

In this study our main goal is to evaluate the role of ultrasonography (USG) for determination of placental maturity and fetal gestational age. This cross-sectional study was done at the Department of Radiology and Imaging (USG section) Mymensingh Medical College and Hospital, Mymensingh from July 2008 to June 2010, where 60 patients included in this study, who was attending in the department of Radiology & Imaging for transabdominal ultrasonography with early and late pregnancy related complaints. In this study among the 60 patients, the youngest one was eighteen years and oldest one was thirty-nine years old age. Thirty five percent (35.0%) patients were from 26-30 years age group. About 33 patients out of 60(55.0%) were house wives. Most of the patients were presented with amenorrhea (65.0%) 39 out of 60. Among 60 patients, 20 patients (33.3%) were in gestational age within 12-28 weeks, 20 patients (33.3%) were in gestational age within 29-36 weeks and 20 patients (33.3%) were within >36 weeks gestational age. Among them, 20 patients (33.3%) had grade III placenta, 20 patients (33.3%) had grade II placenta, 12 patients (20%) had grade I placenta and 08 patients (13.3%) had grade 0 placenta. Out of 60 patients, 18 patients (30.0%) were in high risk group and 70.0% were normal. Six (6) patients (10.0%) suffered from HTN, 3 patients had RH negative (5.0%) blood group, 3(5.0%) patients suffered from APH, 3 patients suffer from DM and 3 from IUGR. In this study showed hypertension and IUGR had strong correlation with accelerated placental maturation. Maternal DM and Rh sensitization were associated with delayed maturation of the placenta. This study concludes that, USG appears to be the best imaging modality for the evaluation of placenta and its grading. USG is relatively less expensive and it is good considering the diagnostic accuracy in pregnancy profile. It is noninvasive procedure without any radiation hazards and better visualization of the lesion in different section, but this study is not a complete reflection of overall incidence and statistics regarding the ailment in our country. For this a more extensive study over a longer period covering different section of society is very much needed for better outcome.

Identification of a Potent Cytotoxic Pyrazole with Anti-Breast Cancer Activity That Alters Multiple Pathways

In this study, we identified a novel pyrazole-based derivative (P3C) that displayed potent cytotoxicity against 27 human cancer cell lines derived from different tissue origins with 50% cytotoxic concentrations (CC50) in the low micromolar and nanomolar range, particularly in two triple-negative breast cancer (TNBC) cell lines (from 0.25 to 0.49 µM). In vitro assays revealed that P3C induces reactive oxygen species (ROS) accumulation leading to mitochondrial depolarization and caspase-3/7 and -8 activation, suggesting the participation of both the intrinsic and extrinsic apoptotic pathways. P3C caused microtubule disruption, phosphatidylserine externalization, PARP cleavage, DNA fragmentation, and cell cycle arrest on TNBC cells. In addition, P3C triggered dephosphorylation of CREB, p38, ERK, STAT3, and Fyn, and hyperphosphorylation of JNK and NF-kB in TNBC cells, indicating the inactivation of both p38MAPK/STAT3 and ERK1/2/CREB signaling pathways. In support of our in vitro assays, transcriptome analyses of two distinct TNBC cell lines (MDA-MB-231 and MDA-MB-468 cells) treated with P3C revealed 28 genes similarly affected by the treatment implicated in apoptosis, oxidative stress, protein kinase modulation, and microtubule stability.

Eight weeks of combined exercise training do not alter circulating microRNAs-29a, -133a, -133b, and -155 in young, healthy men

PURPOSE

Individuals with a family history of type 2 diabetes (FH +) have an increased risk of developing type 2 diabetes. Circulating microRNAs (miRNAs) have been implicated as biomarkers of type 2 diabetes risk. Here, we investigated if four circulating miRNAs related to glucose metabolism were altered in men with a FH + and we conducted a preliminary analysis to determine if miRNA expressions were responsive to 8 weeks of combined exercise training.

METHODS

Sixteen young healthy men (mean ± SD; age 22.5 ± 2.5; BMI 26.4 ± 4.0) with FH + or without a family history of type 2 diabetes (FH -) underweight 8 weeks of combined endurance and resistance exercise training (n = 8 FH -; n = 8 FH +). The expression of miR-29a, miR-133a, miR-133b, and miR-155 were measured in serum before and after exercise training. QIAGEN's Ingenuity^® Pathway Analysis was used to examine miRNA target genes and their involvement in glucose metabolism signaling pathways.

RESULTS

There were no differences in miRNA expressions between FH - and FH + . Exercise training did not alter miRNA expressions in either FH - or FH + despite improvements in insulin sensitivity, aerobic capacity, and muscular strength. miR-29a and miR-155 were inversely related to fasting glucose, and miR-133a and miR-133b were negatively correlated with glucose tolerance; however, correlations were not observed with insulin sensitivity.

CONCLUSIONS

The circulating miRNAs- miR-29a, miR-133a, miR-133b, and miR-155 are related to measures of glucose metabolism in healthy, normoglycemic men, but do not reflect peripheral insulin sensitivity or improvements in metabolic health following 8 weeks of combined exercise training.

The HRCT Evaluation of 105 Suspected COVID 19 Patients of MMCH and RT-PCR Correlation

In this study our main goal is to evaluate the HRCT evaluation of 105 suspected COVID 19 patients of MMCH and RT-PCR correlation. This experimental and observational study was done at Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from May 2020 to October 2020. Where 105 suspected COVID 19 patients of MMCH and RT-PCR correlation were included in the study. During the study, 43.05% of the patients exposed indirectly to the virus, followed by 44.1% didn't exposed any virus, 21% exposed directly. Diabetes mellitus was 35.7%, HTN - 46.2%, 82.95% had fever, 72.45% had cough, 78.75% had respiratory distress and 49.35% had no diseases. After CT scan diagnosis, positive to infection were found in 98 patients, among them 34 patients had mild type, 22 had severe type of infection where as in RT-PCR diagnosis 69 were positive and 36 were negative to infection. From our study we can conclude that, the most common pattern of COVID-19 pneumonia on HRCT images are pure GGO and GGO and Crazy Paving. Also GGO with consolidation with prominent distribution in the posterior and peripheral part of the lung. Further study is very much needed for better outcome.

Differential Expression of Non-Coding RNA Signatures in Thyroid Cancer between Two Ethnic Groups

Filipino Americans show higher thyroid cancer recurrence rates compared to European Americans. Although they are likely to die of this malignancy, the molecular mechanism has not yet been determined. Recent studies demonstrated that small non-coding RNAs could be utilized to assess thyroid cancer prognosis in tumor models. The goal of this study is to determine whether microRNA (miRNA) signatures are differentially expressed in thyroid cancer in two different ethnic groups. We also determined whether these miRNA signatures are related to cancer staging. This is a retrospective study of archival samples from patients with thyroid cancer (both sexes) in the pathology division from the last ten years at Loma Linda University School of Medicine, California. Deidentified patient demographics were extracted from the patient chart. Discarded formalin-fixed paraffin-embedded tissues were collected post-surgeries. We determined the differential expressions of microRNA in archival samples from Filipino Americans compared to European Americans using the state-of-the-art technique, HiSeq4000. By ingenuity pathway analysis, we determined miRNA targets and the pathways that those targets are involved in. We validated their expressions by real-time quantitative PCR and correlated them with the clinicopathological status in a larger cohort of miRNA samples from both ethnicities. We identified the differentially upregulated/downregulated miRNA clusters in Filipino Americans compared to European Americans. Some of these miRNA clusters are known to target genes that are linked to cancer invasion and metastasis. In univariate analysis, ethnicity and tumor staging were significant factors predicting miR-4633-5p upregulation. When including these factors in a multivariate logistic regression model, ethnicity and tumor staging remained significant independent predictors of miRNA upregulation, whereas the interaction of ethnicity and tumor staging was not significant. In contrast, ethnicity remained an independent predictor of significantly downregulated miR-491-5p and let-7 family. We provide evidence that Filipino Americans showed differentially expressed tumor-tissue-derived microRNA clusters. The functional implications of these miRNAs are under investigation.

Traditional knowledge about medicinal plant in the remote areas of Wari Tehsil, Dir Upper, Pakistan

Traditional medicine is cheaper and easily available to local people, to care for most frequent diseases in the Northern parts of Pakistan. Our study aimed at inventorying medicine from local plants, documenting their uses, and assessing their market value in 2015-2018 during spring, summer, and winter seasons. A total of 15 trips were made, 5 in each season. Semi-structured interviews with 165 inhabitant's age range between 20-80 years were conducted, analyzed the data is analyzed using Relative frequency of citation(RFC), Use Value(UV), Fidelity Level(FL), Informants consensus factor(ICF), and Jaccard index(JI) to find the most frequent and well-known used species in the area. A total of 86 species belonging to 39 vascular plant families, 33 genera were documented as medicinally important. Family Asteraceae was observed as the dominant family among all the families with 10 species, the leaf was the most used parts and decoction 36% was the most preferred preparation type. Herb was the predominant life form (67%). The maximum UV (0.92) was demonstrated by J. adhatoda L. species, while A. sativum L. shows maximum RFC (0.58), the highest ICF value represented by diarrhea and dermatitis 0.92, and high FL value is recorded 100%. According to our collections, wild species were 45%, invasive species were 38% and cultivated 17% recorded, dicots species were recorded more 81%. Seven 7 medicinal species is being economically important and export to the local and international market of the world, whereas P. integrima L. species were the most exported species according to the local dealers. The investigated area is rural and the local people depend on the area's plants for their health needs, and other uses like a vegetable, fuelwood, fodder, etc. The current result of RFC, UV, ICF, FL, and JI shows that medicinal flora needs to be pharmacologically and phytochemically investigated to prove their efficacy. The documentation of medicinal knowledge is important to preserve this precious old knowledge before it is lost forever, due to technological and environmental changes in the world.

Treatment With Suboptimal Dose of Benznidazole Mitigates Immune Response Molecular Pathways in Mice With Chronic Chagas Cardiomyopathy

Chronic Chagas cardiomyopathy (CCC) is the most frequent and severe form of Chagas disease, a neglected tropical illness caused by the protozoan Trypanosoma cruzi, and the main cause of morbimortality from cardiovascular problems in endemic areas. Although efforts have been made to understand the signaling pathways and molecular mechanisms underlying CCC, the immunological signaling pathways regulated by the etiological treatment with benznidazole (Bz) has not been reported. In experimental CCC, Bz combined with the hemorheological and immunoregulatory agent pentoxifylline (PTX) has beneficial effects on CCC. To explore the molecular mechanisms of Bz or Bz+PTX therapeutic strategies, C57BL/6 mice chronically infected with the T. cruzi Colombian strain (discrete typing unit TcI) and showing electrocardiographic abnormalities were submitted to suboptimal dose of Bz or Bz+PTX from 120 to 150 days postinfection. Electrocardiographic alterations, such as prolonged corrected QT interval and heart parasite load, were beneficially impacted by Bz and Bz+PTX. RT-qPCR TaqMan array was used to evaluate the expression of 92 genes related to the immune response in RNA extracted from heart tissues. In comparison with non-infected mice, 30 genes were upregulated, and 31 were downregulated in infected mice. Particularly, infection upregulated the cytokines IFN-γ, IL-12b, and IL-2 (126-, 44-, and 18-fold change, respectively) and the T-cell chemoattractants CCL3 and CCL5 (23- and 16-fold change, respectively). Bz therapy restored the expression of genes related to inflammatory response, cellular development, growth, and proliferation, and tissue development pathways, most probably linked to the cardiac remodeling processes inherent to CCC, thus mitigating the Th1-driven response found in vehicle-treated infected mice. The combined Bz+PTX therapy revealed pathways related to the modulation of cell death and survival, and organismal survival, supporting that this strategy may mitigate the progression of CCC. Altogether, our results contribute to the better understanding of the molecular mechanisms of the immune response in the heart tissue in chronic Chagas disease and reinforce that parasite persistence and dysregulated immune response underpin CCC severity. Therefore, Bz and Bz+PTX chemotherapies emerge as tools to interfere in these pathways aiming to improve CCC prognosis.

A Rare Case of Polyorchidism: Sonographic and MR Evaluation of Four Testes

Polyorchidism is a rare congenital anomaly reported about 200 cases in the world text. A number of theories have been planned concerning the making of polyorchidism, but the real explanation is still not acknowledged. Here we are going to present a case study of polyorchidism. A 70 years old gentleman complained with left supernumerary testes in the left hemiscrotum. His left hemiscrotum was painless with mass. Polyorchidism without malignancy or any other concomitant features were revealed by both ultrasound and MRI examinations. In most cases the ultrasonograph alone is diagnostic. In complicated cases of polyorchidism MRI may provide additional information.

Risk Factors of UTI in Children with Nephrotic Syndrome

Urinary tract infection (UTI) is a common complication in nephrotic children and leads to most morbidity and mortality in developing countries like Bangladesh. This case control study was conducted in the Department of Pediatrics and Pediatric Nephrology ward of Dhaka Medical College Hospital, Dhaka from July 2016 to June 2018 to identify the risk factors of UTI in children with nephrotic syndrome. Total 90 patient of nephrotic children aged 2-12 years, who were fulfilling the inclusion and exclusion criteria were selected as Group I (case) and Group II (control) according to urine culture report. Group I was UTI positive and Group II was UTI negative. The mean age of Group I was 5.26±3.18 years and Group II was 6.03±2.85 years. There was male predominance in both groups. No significant difference has been found regarding age and sex (p>0.05). No significant difference was also observed regarding economic status and educational level of mother among both groups (p>0.05). Fever, dysuria, abdominal pain, anasarca, vomiting and pallor were found as common presentations in Group I. Children with dysuria and abdominal pain were significantly higher in Group I than Group II (p value <0.001). UTI was found more in relapsed cases than initial attack. E. coli was the most common etiologic agent (37.8%). Mean Hb (gm/dl), serum total protein, serum albumin and serum IgG level were found significantly lower and spot urine protein creatinine ratio was significantly higher in Group I, which implies that those biochemical factors were associated with development of UTI in nephrotic children. Younger age group (<6 years), Constipation and uncircumcised male were found as risk factors and has association with UTI in nephrotic children.

Chest Radiography in the Evaluation of Mitral Valvular Disease and it's Correlation with Echocardiography

This study is aimed to find out various clinical, radio-graphical and echocardiographic variables to predict mitral valvular disease and their correlation with Echocardiography. This cross-sectional observational study was conducted in the Department of Radiology and Imaging, in collaboration with Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2017 to December 2018. Total 50 consecutive cases enrolled in this study who was the patients of mitral valvular disease. Both chest radiograph and echocardiograph were done for each patient. There were 76% female and 26% male with a female-male ratio 3.16:1 with mean±SD (41.54±12.44). About 42% patients had previous history of rheumatic fever. The most common x-ray findings of heart were increased central density (90%) followed by enlargement in transverse diameter (88%), straightening of the left border (88%), widening of the carina (86%), full pulmonary conus (84%) and double contour of right border (76%). About 47(94%) patients confirmed mitral valvular heart disease on echocardiography. The prominent findings included left atrium was predominantly severely dilated (50%), severely reduced mitral valve orifice area (68%), mild mitral regurgitation (46%) and mild pulmonary hypertension (38%). And overall sensitivity, specificity, PPV, NPV and accuracy of chest radiograph in the detection of mitral valvular heart disease were 85.11%, 66.67%, 97.56%, 14.89% and 84%, respectively. These findings suggest that chest radiograph could be used as an adjunct tool with echocardiography.

Association between Child Undernutrition and Maternal Undernutrition: A Study in a Tertiary Care Hospital

Undernutrition in children under five years remains a significant health problem in Bangladesh, despite substantial socio-economic progress and a decade of interventions aimed at improving it. Although Bangladesh has made rapid progress over the last decade in the field of health and nutrition, there has been very slow progress in improving the state of child nutrition. Studies aiming at determination of interrelationship between child undernutrition and maternal undernutrition are to be scientifically established if appropriate intervention policy is to be introduced. This study was undertaken to see whether this assumption has a statistically proven basis that maternal undernutrition influences child undernutrition. The objective of this cross sectional analytical study was to evaluate the association between child undernutrition and their maternal undernutrition in child-mother pair in a tertiary care hospital and was conducted from July 2017 to April 2018 in the department of General Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study subjects were 196 children between the ages of six months to five years who were admitted in BSMMU and their accompanying mothers. Children who had any known chronic diseases or clinically obvious syndrome were excluded. Before enrollment, parents of all the patients were informed about the study & its objectives. Anthropometric measurements of children and mothers were done by standard procedure. Demographic profile and relevant maternal information were collected by interviewing the mothers. Among the undernourished children, 17.3% were found underweight, 7.1% stunted, 16.3% wasted. Combined underweight & wasted were 34.7%, underweight & stunted 9.2%, stunted & wasted 5.1%, underweight, stunted and wasted 10.2%. Maternal undernutrition was more common (95.7%) in undernourished children group. Undernutrition was significantly higher in mothers of children with undernutrition (OR=40.75, p<0.001). Children having a better nutrition were born from mothers who were well nourished, educated, had good childcare knowledge and higher family income. This emphasized the need to provide the guideline for appropriate measure to be taken to reduce child undernutrition.

Depression among Patients Presenting with Gastrointestinal Symptoms: Prevalence and Associated Factors

Gastrointestinal diseases frequently affect patients' physical and emotional wellbeing as being heavily affected by stress. This study was conducted to find out prevalence and severity of depressive symptoms among patients presenting with gastrointestinal symptoms. This cross sectional study was conducted at Outpatients Department jointly by Department of Gastroenterology and Department of Psychiatry of a tertiary care hospital in north east part of Bangladesh from November 2011 to June 2012. Consecutive patients with gastrointestinal symptoms underwent psychiatric evaluation using HDRS and analyzed. 442 patients, 38(8.6%) were found normal. Among the rest 128(28.96%), 138(31.22%), 72(16.29%) and 66(14.93%) had mild, moderate, severe and very severe depressive symptoms respectively. Female sex (95.03% vs. 89.32%), married people (93.77 vs. 86.13%), older age (98.24%), rural people (94.26% vs. 84.36%), farmers (96.36%) and house wives (96.24%) were more affected. Prevalence of depression was also higher among patients with lower socioeconomic class, less educated people and rural background. Depressive symptoms are very common in patients presenting with gastrointestinal symptoms. Awareness regarding psychiatric assessment and intervention may reduce sufferings and thus improve wellbeing of these patients.

Risk factors for non-communicable diseases related to obesity among first- and second-generation Bangladeshi migrants living in north-east or south-east England

BACKGROUND

Obesity is a global burden, which significantly increases the risk of non-communicable diseases (NCDs). More than a quarter of adults in the United Kingdom are obese, but prevalence varies by ethnicity, and South Asians have the largest burden of NCDs. This paper assesses how sex, generation, and region interplay to vary the predisposition to obesity-related (OR) NCDs among UK Bangladeshis.

METHODS

We used National Institute for Health and Care Excellence suggested grading for combining body mass index and waist circumference to define populations at risk of OR-NCDs. Data from 517 adults of Bangladeshi origin from a cross-sectional study (March 2013 to April 2015) were analysed. Male and female participants from London and north-east England were equally sampled including: (1) adult migrants, who came to the UK aged >16 years; (2) child migrants, who came to the UK aged ≤16 years; and (3) second-generation Bangladeshis (who were born and brought up in the UK). A generalised estimating equation using a binomial distribution and a logit link was used to explore the relationship between the binary outcome of being 'at risk of OR-NCDs' and associated factors.

RESULTS

Females, married individuals, those living in London, the second-generation, and those of lower self-assessed financial status, with low acculturation status, or who did not walk daily for at least 20 min were more likely to develop OR-NCDs. A striking sex difference was found with more females prone to OR-NCD risk in the north-east than in London.

CONCLUSIONS

Our study observed important inter- and intra-regional inequality in OR-NCD risk which worsens the health of ethnic minorities and widens inequality.

GPCR-PEnDB: a database of protein sequences and derived features to facilitate prediction and classification of G protein-coupled receptors

G protein-coupled receptors (GPCRs) constitute the largest group of membrane receptor proteins in eukaryotes. Due to their significant roles in various physiological processes such as vision, smell and inflammation, GPCRs are the targets of many prescription drugs. However, the functional and sequence diversity of GPCRs has kept their prediction and classification based on amino acid sequence data as a challenging bioinformatics problem. There are existing computational approaches, mainly using machine learning and statistical methods, to predict and classify GPCRs based on amino acid sequence and sequence derived features. In this paper, we describe a searchable MySQL database, named GPCR-PEnDB (GPCR Prediction Ensemble Database), of confirmed GPCRs and non-GPCRs. It was constructed with the goal of allowing users to conveniently access useful information of GPCRs in a wide range of organisms and to compile reliable training and testing datasets for different combinations of computational tools. This database currently contains 3129 confirmed GPCR and 3575 non-GPCR sequences collected from the UniProtKB/Swiss-Prot protein database, encompassing over 1200 species. The non-GPCR entries include transmembrane proteins for evaluating various prediction programs' abilities to distinguish GPCRs from other transmembrane proteins. Each protein is linked to information about its source organism, classification, sequence lengths and composition, and other derived sequence features. We present examples of using this database along with its graphical user interface, to query for GPCRs with specific sequence properties and to compare the accuracies of five tools for GPCR prediction. This initial version of GPCR-PEnDB will provide a framework for future extensions to include additional sequence and feature data to facilitate the design and assessment of software tools and experimental studies to help understand the functional roles of GPCRs.

Characterization of Clostridioides difficile ribotypes in domestic dogs in Rio de Janeiro, Brazil

Clostridioides difficile is the major etiologic agent of nosocomial bacterial diarrhoea and pseudomembranous colitis. The pathogenesis of C. difficile infection (CDI)involves two cytotoxic enzymes (TcdA, TcdB) that cause colonic epithelial damage, fluid accumulation and enteritis. CDI has been demonstrated in a variety of animal species and some reports have recently raised the importance of wild animals as a reservoir of this pathogen and possible transmission to humans and domestic animals. The aim of this study was to characterize C. difficile isolates obtained from pet dogs in Rio de Janeiro, Brazil. A total of 50 faecal samples were obtained from healthy and diarrheic dogs. Five of fifty samples (10%) grew C. difficile. Of those, three belonged to the PCR ribotype 106 (ST 42) and were toxigenic (A⁺B⁺). The other two strains belonged to the PCR ribotype 010 (ST 15) and were not toxin producers (A^-B^-). None of the isolates tested positive for the binary toxin genes. Considering the antimicrobial resistance patterns of all isolates using EUCAST breakpoints, all strains were sensitive to metronidazole and vancomycin. However, two strains (ribotype 106 and ribotype 010), were resistant to clindamycin (≤256 μg/mL). All strains were strong biofilm producers. Our study provides evidence that dogs can act as reservoirs for C. difficile epidemic ribotypes.

Substance Use among the Patients with First Episode Psychosis

Substance Use Disorder is a frequent problem in Bangladesh and many of these patients develop psychosis. Substance use can cause psychosis and it can modify the course of psychosis. This cross-sectional study was done to see the proportion of substance use in patients with First-Episode Psychosis (FEP) in two tertiary care hospitals in Dhaka, Bangladesh mentioned here as Bangabandhu Sheikh Mujib Medical University and Dhaka Medical College Hospital; from November 2007 March 2009. Fifty consecutive FEP patients were taken as subjects and 50 healthy attendants were recruited as control. Mean age of the patients was 27.24, male (62%) are more having first-episode psychosis than female (38%). Majority of the patients were unmarried (64%). Regarding occupation students were 34%, followed by unemployed 24% and service18%. In control group's occupation; service 34%, housewife 22%. Life time substance use was found double in patients with first-episode psychosis than control. Cannabis was found to be the most common substance causing psychosis. Among the lifetime substance users in fist-episode psychosis patients 77.78% were male where as, in control group 100% patients were male. However, the researcher did not find any of the first-episode psychosis patients taking current use of substance (abuse and /or dependence). The small size of the present study was only 50. Future prospective study is required having large sample size to see the outcome of substance use in first-episode psychosis.

Ultrasonographic Evaluation of Malignant Pediatric Abdominal Tumour with Histopathological Correlation

Ultrasonography is a very useful diagnostic tool to evaluate pediatric abdominal mass. This cross sectional study was conducted among clinically suspected patients having malignant abdominal mass attending in the department of Radiology & Imaging, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2008 to December 2009. Total 56 patients were included in this study. Patients were scanned by high resolution gray scale ultrasonography of the abdominal masses. After surgical procedure, biopsy specimen were collected in a container containing 10% formalin and sent for histopathological examination. Mean age of the patients group was 5.91 years with a standard deviation of ±3.21 years. All patients were within 2 to 13 years age. Out of all patients, male were 33(58.9%) and 23(41.1%) were female. Male and female ratio was 1.4:1. Ultrasonographic diagnosis as Wilm's tumour were 27(48.2%), hepatoblastoma 8(14.3%), lymphoma 7(12.5%), neuroblastoma 6(10.7%), suspected malignancy 6(10.7%) and lastly teratoma were 2(3.6%). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of ultrasonography in the evaluation of Wilm's tumour were 100.0%, 90.6%, 88.9%, 100.0% and 94.6% for neuroblastoma 83.3%, 98.0%, 83.3%, 98.0% and 96.4% for lymphoma 83.3%, 96.0%, 71.4%, 98.0% and 94.6% and for hepatoblastoma 100.0%, 100.0%, 100.0%, 100.0% and 100.0% respectively. It is a noninvasive and cost effective modality. Carefully performed ultrasonographic study would give reliable and accurate information needed in the diagnosis of abdominal malignancy in children.

Risk Factors and Immediate Outcome of Very Low Birth Weight Babies (Appropriate For Gestational Age) In Newly Established SCANU, Mymensingh Medical College Hospital

Low birth weight (LBW) is the most important preventable cause in the neonatal period leading to very high neonatal mortality and morbidity in developing countries like Bangladesh. A cross sectional study was conducted in the neonatology ward, Mymensingh Medical College Hospital, Mymensingh from July 2014 to December 2014 to identify the risk factors and immediate hospital outcome of Very Low Birth Weight (VLBW) Appropriate for Gestational Age (AGA) babies in context of present neonatal hospital care standard. Total 100 preterm very low birth weight babies were enrolled and selected by weight, intra uterine growth chart and new ballad score. There is slight preponderance of male babies (64%) over female babies (36%). The overall survival and mortality rate was 50% and 50% respectively in the present study. Mortality is highest (76.47%) in babies whose gestational age 28 weeks and the mortality rate gradually decrease as gestational age increases. Correlation co-efficient (r) between gestational age and number of died is -0.85. It indicates highly opposite relation between the variables, p value (<0.069) which is strong opposite relation. Mortality is highest (66.66%) in babies whose birth weight below1100gm, in comparison to those whose birth weight above 1100gm and correlation co-efficient (CC) r = -0.433 (p<0.466) which is not significant. That means not only birth weight but also other factors are responsible for mortality of very low birth weight baby. Neonatal mortality bears inverse relationship with birth weight and gestational age. This emphasized the need for large scale study which will provide the guideline for appropriate measures to be taken to combat the situation.

Granulomatosis with Polyangiitis (Wegener Granulomatosis) with Unusual Presentation

We came across a 32 years old male admitted in our hospital with prolonged low-grade fever, haemoptysis, leg swelling, weight loss, purpuric rashes and malaena. He received anti-TB treatment at another hospital without any improvement. He was pale with bullous and purpuric lesions over legs and feet. He also had features of consolidation over both lung fields. His CRP was 312mg/L, Urine R/M/E showed 40-50 RBC/HPF, Chest X-ray showed features of bilateral consolidation, c-ANCA-10U/L (positive); Tracheal aspirate for AFB was found to be negative. We diagnosed the case as Granulomatosis with Polyangitis (WG) and started treatment with steroid and cyclophosphamide. But the patient could not be saved probably due to delay in starting management.

Doppler Assessment of Hepatic Venous Waves for Evaluation of Large Varices in Cirrhotic Patient

This cross sectional study was conducted to evaluate the role of doppler ultrasonography of hepatic venous waves for evaluation of large varices in cirrhotic patients from July 2013 to June 2015 in Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Patients getting admitted in the ward with a diagnosis of cirrhosis were enrolled in the study and purposive sampling technique was adopted. The sample size was 43. Data were collected by face to face interview and some data were gathered by records review and analyzed with the help of SPSS windows version - 12 software programs. Statistical significance was set at P<0.05 and confidence interval set at 95%. The research protocol was approved by the local ethical committee. Esophagogastroduodenoscopy is the gold standard for the diagnosis of esophageal varices. If the gold standard is not available, other possible diagnostic steps would be Doppler ultrasonography of the blood circulation (not endoscopic ultrasonography). Although and it can certainly demonstrate the presence of varices. In 60.47% of patient's monophasic wave pattern was seen and in 39.53% of cases biphasic & triphasic wave pattern were detected. Endoscopic examination was performed in all selected patients. In this study, 67.44% is large varices, 32.66% is small varices. Chi Square test was done for hypothesis testing and it was found significant (<0.05) and it indicates monophasic wave in Doppler USG signifies large varices. This test was also done to find out whether any significant difference of hepatic venous waveform in between male and female but it was not significant (>0.05). Diagnostic performance of USG for evaluation of varices showed, Sensitivity: 86.2%, Specificity: 92.85%, PPV: 96%, NPV: 76.47%, Accuracy 88%. Correlation co-efficient was 0.0064 which indicates moderately positive correlation in between monophasic hepatic venous waveform pattern by Doppler USG and large varices in oesophagogastroduodenoscopic findings Normal hepatic wave form shows triphasic pattern. Loss of this pattern in cirrhosis is mainly due to loss of compliance of liver. In conclusion, the loss of triphasic pattern of hepatic wave form is highly sensitive in predicting the presence of large varices in cirrhotic patients and this doppler parameter may be used as a non-invasive test for cirrhotic patients, who wish to avoid upper GI endoscopy. Further studies using a combination of various doppler parameters are needed to create indices with a better predictive value.

Correlation between Umbilical Cord Diameter and Cross Sectional Area with Gestational Age and Foetal Anthropometric Parameters

The objective of the study was to find out correlation between umbilical cord diameter, cross sectional area with gestational age and foetal anthropometric parameters. This cross sectional study was conducted among healthy women between the 24(th) and 40(th) completed weeks of a normal pregnancy in the Department of Radiology & Imaging, Mymensingh Medical College Hospital, Mymensingh during the study period, from July 2009 to June 2011. A total of 230 consecutive normal pregnancy patients were included in the study. The diameter & cross-sectional area of the umbilical cord were measured on a plane adjacent to the junction of the umbilical cord and the fetal abdomen, in cross-section, with maximum magnification of the image. The cord was manually circled, and it's cross sectional areas was automatically calculated by the ultrasonograph. The mean±SD age was 24.3±4.7 years with range from 19 to 36 years. The mean gestational age was 32.1±4.5 weeks and more than a half (56.4%) of the pregnant women were nulliparas. A positive significant (p<0.001) correlation were found between umbilical cord diameter with bi-parietal diameter (r=0.548); head circumference (r=0.411); abdominal circumference (r=0.444); femur length (r=0.366) and gestational age gestation age (r=0.643). Similarly, a significant (p<0.001) positive week correlation were found between umbilical cross sectional area with bi-parietal diameter (r=0.3303); head circumference (r=0.3202); abdominal circumference (r=0.2651); femur length (r=0.3307) and gestation age (r=0.4051). A positive significant better correlation was found with umbilical cord diameter than cross sectional area with foetal anthropometric parameters.

Role of D-dimer in determining coagulability status in pre-eclamptic and normotensive pregnant women

A cross sectional study was carried out from January 2007 to December 2008 in the department of Obstetrics and Gynaecology, Dhaka Medical College Hospital, Dhaka in collaboration with Department of Haematology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Pregnant women with pre-eclampsia attending at Out-patient Department (OPD) and admitted in In-patient Department of Obstetrics and Gynaecology Dhaka Medical College Hospital, Dhaka were selected as cases. Healthy and uncomplicated pregnant women admitted in the same hospital were taken as controls. The study showed that 26-30 years and 21-25 years age category was higher in the case and control groups and the mean age was significantly higher in case group compared to control group (p=0.025). The study showed that 44% of case group had a significantly high level of plasma D-dimer (>0.5μg/ml) as opposed to control group (8%) (p<0.001). Estimation of odds ratio demonstrates that pre-eclamptic women (case) had 9 times (95% of CI = 2.8 - 28.9) more risk of having plasma D-dimer >0.5μg/ml than that of normal pregnant women (control). The mean systolic and diastolic blood pressures in patients with plasma D-dimer >0.5μg/ml were considerably higher than those who had plasma D-dimer ≤0.5μg/ml (p<0.001). The study showed that majority (81.8%) of pre-eclamptic women with plasma D-dimer >0.5μg/ml had systolic blood pressure ≥ 160 mm Hg compared to 46.4% of those who had plasma D-dimer ≤0.5μg/ml (p=0.010). And ninety percent of pre-eclamptic women with plasma D-dimer >0.5μg/ml had exhibited severe proteinuria as opposed to 53.6% of those who had plasma D-dimer ≤0.5μg/ml (p=0.017). The study concludes that plasma D-dimer level can easily be used in screening for the hypercoagulable state in pre-eclamptic patients which have preventive and therapeutic implications.

Determination of toxic trace elements in foodstuffs, soils and sediments of bangladesh using instrumental neutron activation analysis technique

The concentrations of arsenic (As), chromium (Cr) and iron (Fe) were determined in the foodstuffs, soils and sediments from various areas in Bangladesh and new data for these toxic trace elements were given. The arsenic pollution problems in the most of the areas of Bangladesh are of geological origin. The high level of As in foodstuffs, soils and sediments, except for tannery sediments is probably positively correlated to the Fe concentration. An excessive amount of chromium was found in the sediments from the tannery area of Bangladesh.

Effect of standard treatment guidelines with or without prescription audit on prescribing for acute respiratory tract infection (ARI) and diarrhoea in some thana health complexes (THCs) of Bangladesh

Inappropriate prescribing for ARI and diarrhoea is a serious health problem in many developing countries including Bangladesh. A baseline retrospective prescribing survey for ARI and diarrhoea have been conducted in randomly selected 60 thana health complexes (THCs) of Dhaka division of Bangladesh. In the 38 of 60 THCs, the prescribers did not comply with the standard treatment guidelines (STG) for ARI. They are marked as 'unsatisfactory performers'. In these THCs unnecessary antibiotics were prescribed in more than 50% of the encounters. The study further revealed that in 26 THCs, comprising 41.6% of the 38 THCs, the situation was even worse regarding the indiscriminate use of antibiotics. In these THCs antibiotics were prescribed in > or =72% of the encounters. For diarrhoea, only in 8.3% of the THCs antibiotics were prescribed in > or =50% of the encounters. Encouragingly, most of the prescribers prescribed ORS. So the diarrhoea cases were dropped from the intervention. The 24 out of 26 worse performing THCs for ARI management, were grouped into three groups: Group-I (implementing STG+ Audit), Group-II (STG) and Group-III (no intervention, control). The prescribers of the THCs belonging to Group-I and Group-II received STG+Audit and STG only respectively as intervention(s). On the contrary, the prescribers of the THCs of Group-III (control) did not receive any intervention. It was observed that after the implementation of interventions the use of the unnecessary antibiotics to treat ARI was significantly reduced (p<0.01) compared to pre-intervention period in Group-I (STG+Audit). In this group highly significant (p<0.000) reduction in antibiotics use was achieved in 6 out of 8 THCs. The average reduction in antibiotic use in terms of encounters was 23.7 and 15.2% in the Group-I and Group-II respectively owing to the intervention(s). Significant reduction in antibiotic use in terms of THCs was 3 (out of 8 THCs) and 2 (out of 8 THCs) belonging to the Group-II and Group-III respectively. When compensated for the change in the control group, the reduction of antibiotic use in terms of encounters was 15.2 and 6.9% in the THCs of the Group-I and Group-II respectively due to introduction of the interventions. The study concludes that STG supported by prescription audit are highly effective interventions to change the prescribing behaviour of the prescribers for ARI in the THCs.

Endometriosis association research center

Endometriosis, the presence of endometrial tissue outside the uterus, is a progressive, estrogen-dependent disease and occurs nearly exclusively in menstruating women of reproductive age. Pain syndrome, however, represents the major clinical problem of this disease, manifested as dysmenorrhea, pelvic pain, lower abdominal pain, and dyspareunia. About 32 literatures are reviewed in recent advancement for diagnosis of endometriosis. The magnifications of its managements are understood. In outdoor, the management is only depending on clinical findings and on some non invasive procedures without any definitive diagnosis. So, research activities should be done on the basis of recent advancement of endometriosis.

Synthesis and fungicidal activity of some 5-aryl/aryloxymethyl-2-[5-aryl-3-methyl-1,2,4-triazol-2-yl]-1,3,4-thiadiazoles and 5-aryl/aryloxymethyl-2[5-aryl-2-phenylimino-1,3,4- thiadiazolin-3-yl]-1,3,4-thiadiazoles

5-Aryl/aryloxymethyl-2-[5-aryl-2-methyl-1,2,4-triazol-2-yl]- 1,3,4-thiadiaxoles 4 and 5-Aryl/aryloxymethyl-2-[5-aryl-2-phenylimino-1,3,4- thiadiazolin-3-yl]-1,3,4-thiadiazoles 5 have been obtained from the cyclocondensation of 5-aryl/aryloxymethyl-2-arylidene hydrazino-1,3,4-thiadiazoles 3 with methyl cyanide and phenyl isothiocyanate respectively. Compounds 4 & 5 have been screened for their fungicidal activity against R. solani, F. oxysporum and P. oryzae. Based on screening data some structure-activity relationship is given.

Analysis of Pfmdr 1 gene in mefloquine-resistant Plasmodium falciparum

Drug resistance in Plasmodium falciparum is a serious problem in most endemic areas. Recent studies have suggested the potential involvement of genes in the MDR gene family in resistance to quinoline-containing compounds in P. falciparum. In our present studies, a molecular analysis of pfmdr 1 in isolate strain of P. falciparum, 523a R, from Japanese mefloquine-resistant patient was done to determine the reported association of pfmdr 1 intragenic alleles and mefloquine resistance, and to examine the antimalarial activities of several antimalarial agents against the P. falciparum strain. The antimalarial activities against the strain was decreased susceptibility to mefloquine, artemisinin and halofantrine, in contrast increased susceptibility to chloroquine. The DNA sequence analysis of pfmdr 1 gene in a strain reveled no association of intragenic alleles with mefloquine resistance. Furthermore, the overexpression of pfmdr1 mRNA have been observed and it is about 7.2 times higher than sensitive strain. Our data shows that overexpression of pfmdr1 gene may be associated in mefloquine-resistance mechanism.

Extensive repertoire of membrane-bound and soluble dendritic cell-specific ICAM-3-grabbing nonintegrin 1 (DC-SIGN1) and DC-SIGN2 isoforms. Inter-individual variation in expression of DC-SIGN transcripts

Expression in dendritic cells (DCs) of DC-SIGN, a type II membrane protein with a C-type lectin ectodomain, is thought to play an important role in establishing the initial contact between DCs and resting T cells. DC-SIGN is also a unique type of human immunodeficiency virus-1 (HIV-1) attachment factor and promotes efficient infection in trans of cells that express CD4 and chemokine receptors. We have identified another gene, designated here as DC-SIGN2, that exhibits high sequence homology with DC-SIGN. Here we demonstrate that alternative splicing of DC-SIGN1 (original version) and DC-SIGN2 pre-mRNA generates a large repertoire of DC-SIGN-like transcripts that are predicted to encode membrane-associated and soluble isoforms. The range of DC-SIGN1 mRNA expression was significantly broader than previously reported and included THP-1 monocytic cells, placenta, and peripheral blood mononuclear cells (PBMCs), and there was cell maturation/activation-induced differences in mRNA expression levels. Immunostaining of term placenta with a DC-SIGN1-specific antiserum showed that DC-SIGN1 is expressed on endothelial cells and CC chemokine receptor 5 (CCR5)-positive macrophage-like cells in the villi. DC-SIGN2 mRNA expression was high in the placenta and not detectable in PBMCs. In DCs, the expression of DC-SIGN2 transcripts was significantly lower than that of DC-SIGN1. Notably, there was significant inter-individual heterogeneity in the repertoire of DC-SIGN1 and DC-SIGN2 transcripts expressed. The genes for DC-SIGN1, DC-SIGN2, and CD23, another Type II lectin, colocalize to an approximately 85 kilobase pair region on chromosome 19p13.3, forming a cluster of related genes that undergo highly complex alternative splicing events. The molecular diversity of DC-SIGN-1 and -2 is reminiscent of that observed for certain other adhesive cell surface proteins involved in cell-cell connectivity. The generation of this large collection of polymorphic cell surface and soluble variants that exhibit inter-individual variation in expression levels has important implications for the pathogenesis of HIV-1 infection, as well as for the molecular code required to establish complex interactions between antigen-presenting cells and T cells, i.e. the immunological synapse.

Synthesis and antimalarial activity of novel medium-sized 1,2,4,5-tetraoxacycloalkanes

CsOH- or Ag(2)O-mediated cycloalkylation of (alkylidene)bisperoxides 3 and 1,n-dihaloalkanes (n = 3-8) provided the corresponding medium-sized 1,2,4,5-tetraoxacycloalkanes 4-8 in moderate yields. Subsequent evaluation of the antimalarial activity of the cyclic peroxides 4-8 in vitro and in vivo revealed that 1,2,6,7-tetraoxaspiro[7.11]nonadecane 4a has considerable potential as a new, inexpensive, and potent antimalarial drug.

Health gain and outcome predictors during inpatient and related day treatment in child and adolescent psychiatry

OBJECTIVE

To investigate health gain and its predictors during inpatient and associated day patient treatment.

METHOD

Consecutive admissions to two inpatient units for children and young adolescents in northwest England were studied (N = 55). Ascertainments were made from multiple perspectives, including family, teacher, clinician, and an independent researcher. Measures were taken at referral, admission, discharge, and 6-month follow-up; health gain was inferred from change scores on measures. Recruitment lasted from late 1995 to 1997; follow-up was completed during 1998. Independent variables tested as predictors included assessments of presenting symptoms, therapeutic alliance, and family functioning.

RESULTS

Significant health gain during hospitalization was found on most measures and sustained to follow-up. There was no symptom change during the waiting-list control condition. Health gain was predicted independently by child and parental therapeutic alliance with the unit early in hospitalization and by preadmission family functioning. Externalizing problems did well if accompanied by good alliance.

CONCLUSIONS

Assessment of health gain from multiple perspectives is possible and valuable. Inpatient treatment has significant therapeutic effect. Predictors for health gain lie in process variables of therapeutic alliance and family functioning rather than presenting symptoms. The results are discussed in relation to clinical practice and future research.

Microwave drying of selected greens and their sensory characteristics

Green leafy vegetables which supply minerals and vitamins to the diet, are highly perishable. Therefore, post harvest losses are extremely high. Limited studies are available in the literature with regard to preservation of greens. The effect of microwave drying and storage on physical and sensory properties of selected greens (coriander, mint, fenugreek, amaranth and shepu) were therefore studied. Microwave drying was carried out at 100% power and a frequency of 2450 mHz. The drying time varied from 10 to 16 min for different greens. Microwave drying affected color, appearance and odor of all the greens. The relative reconstitution capacity (RRC) for different greens was coriander-10.3, mint-10.3, amaranth-38.3, fenugreek-31.7 and shepu-32.8. The RRC appeared to influence acceptability. Coriander and mint, which exhibited the lowest RRC (10.3%), had the lowest scores for flavor and color while amaranth, with the highest RRC (38.3%), had scores similar to those of fresh amaranth. Scores for the products prepared with dried fenugreek and shepu, although low, were not statistically significant. Microwave drying was highly suitable for greens such as amaranth; moderately suitable for shepu and fenugreek and less suitable for coriander and mint.

Evolution of human and non-human primate CC chemokine receptor 5 gene and mRNA. Potential roles for haplotype and mRNA diversity, differential haplotype-specific transcriptional activity, and altered transcription factor binding to polymorphic nucleotides in the pathogenesis of HIV-1 and simian immunodeficiency virus

Polymorphisms in CC chemokine receptor 5 (CCR5), the major coreceptor of human immunodeficiency virus 1 (HIV-1) and simian immunodeficiency virus (SIV), have a major influence on HIV-1 transmission and disease progression. The effects of these polymorphisms may, in part, account for the differential pathogenesis of HIV-1 (immunosuppression) and SIV (natural resistance) in humans and non-human primates, respectively. Thus, understanding the genetic basis underlying species-specific responses to HIV-1 and SIV could reveal new anti-HIV-1 therapeutic strategies for humans. To this end, we compared CCR5 structure/evolution and regulation among humans, apes, Old World Monkeys, and New World Monkeys. The evolution of the CCR5 cis-regulatory region versus the open reading frame as well as among different domains of the open reading frame differed from one another. CCR5 cis-regulatory region sequence variation in humans was substantially higher than anticipated. Based on this variation, CCR5 haplotypes could be organized into seven evolutionarily distinct human haplogroups (HH) that we designated HHA, -B, -C, -D, -E, -F, and -G. HHA haplotypes were defined as ancestral to all other haplotypes by comparison to the CCR5 haplotypes of non-human primates. Different human and non-human primate CCR5 haplotypes were associated with differential transcriptional regulation, and various polymorphisms resulted in modified DNA-nuclear protein interactions, including altered binding of members of the NF-kappaB family of transcription factors. We identified novel CCR5 untranslated mRNA sequences that were conserved in human and non-human primates. In some primates, mutations at exon-intron boundaries caused loss of expression of selected CCR5 mRNA isoforms or production of novel mRNA isoforms. Collectively, these findings suggest that the response to HIV-1 and SIV infection in primates may have been driven, in part, by evolution of the elements controlling CCR5 transcription and translation.

Detection of hepatitis B surface antigen in pregnant women attending a public hospital for delivery: implication for vaccination strategy in Bangladesh

Routine antenatal hepatitis B surface antigen (HBsAg) screening and immunization of risk babies is very effective in preventing perinatal transmission of hepatitis B virus (HBV). We studied 1,800 parturients attending a public hospital to assess the rationale for such vaccination in Bangladesh. In one in every 29 deliveries (63 of 1,800 or 3.5%), the mother was found to be HBsAg positive. All were asymptomatic and many (41 of 63 or 65%) without risk factors would remain undetected if HBsAg screening were performed on selected groups. Most of the HBsAg-positive mothers (54 of 63 or 85.7%) were found to be chronic carriers and 30.2% (19 of 63) were also hepatitis B e antigen (HBeAg) positive, indicating high infectivity. Although 23 cord blood were positive for HBsAg or HBeAg, none were positive for IgM antibody to hepatitis B core antigen (IgM anti-HBc), suggesting transplacental transmission of the antigens rather than intrauterine infection. These findings are discussed in relation to the cost-effectiveness of routine prenatal screening and immunization of risk babies compared with universal infant immunization.

Geographical distribution & seasonal pattern of diarrhoeal diseases in Bangladesh

The district wise distribution and seasonal pattern of diarrhoeal diseases from 1987 to 1989 of Bangladesh are compiled and reported. The districts of Lalmonirhat, Kurigram, Gaibandha, Rajbari and Banderban showed higher incidences of diarrhoeal diseases to mean range of 8 and above. Among the remaining districts, 18 districts were in the medium ranges of incidences between 4 to less than 8% and 41 districts with lower range of incidences i.e. less than 4%. Two peaks of diarrhoeal diseases were found, once during the months of September-October in the post monsoon period and other during April-May.

A five-year clinical evaluation of Norplant contraceptive subdermal implants in Bangladeshi acceptors

A non-comparative study of the Norplant contraceptive subdermal implant system was conducted in Dhaka, Bangladesh. The study was designed to evaluate the contraceptive efficacy, safety and overall acceptability of Norplant implants. Six hundred women were enrolled in the clinical trial, which began in 1985 at three study sites. Follow-up visits were scheduled at 1, 3, and 6 months after Norplant implant insertion, and every six months thereafter until removal or at the end of five years. There were no post-insertion pregnancies during Norplant implant use in this study. After five years of Norplant implant use, there was no clinically significant change in body weight, systolic or diastolic blood pressure. Less than 3% of the women ever reported having any significant medical problems such as migraine, respiratory or cardiac problems during the study. The gross cumulative continuation rate was 41.2 per 100 women at the end of five years. The two most frequently reported reasons for discontinuation during the study were menstrual problems and desired pregnancy. Of the women who completed the five-year user satisfaction questionnaire, the majority of the women (86.3%) planned to continue using contraception after study completion. Of these women, approximately one-third said they planned to use another Norplant set. The findings presented suggest that the Norplant system is a highly effective, safe and acceptable method among Bangladeshi women.

Analysis of 20,119 deliveries in Dhaka Medical College Hospital

Data of 20,119 deliveries in Dhaka Medical College Hospital are presented. Dhaka Medical College Hospital is the chief referral hospital in Dhaka city. The 15% of patient were 18 years of age or below and 18% were above 35 years of age or above. The 48.22% were primaegravida and 51.78% were multigravida, of these 28% were grandmultigravida. The 89% had no previous antenatal checkup. The 92.72% had cephalic presentation, 65.52% had normal vaginal delivery, 21.07% had caesarean section, 11.18% had forceps delivery. Perinatal mortality during hospital stay was 143/1,000 deliveries, maternal mortality 2,510/100,000, mainly due to eclampsia. Complications during delivery were mainly in the form of ruptured uterus (1.10%), P.P.H. (1.06%), and retained placenta (3.88%).

Retention of ascorbic acid in pickles--effect of different spices and salt (an in vitro study)

Effect of spices, different concentration of sodium chloride and other salts on retention of ascorbic acid during storage period (21 days in case of spices and eight days for salts) was studied. The retention of ascorbic acid with the addition of 24% NaCl was 55%, followed by 37% with red chillies, fenugreek, turmeric; 32% with the addition of pepper, sugar and 26% with mustard and asafoetida. When all the spices and salt were added together, the retention was much higher (73%) than those with individual spices. Sodium chloride over a wide range of concentrations was found to have higher retention of ascorbic acid. The retention being 80%, when stored with 24.0% sodium chloride solution for eight days. Sulfates of sodium, potassium, magnesium and manganese or chlorides of magnesium or manganese did not have a significant effect on the retention of ascorbic acid. The retention with potassium chloride was close to that observed with sodium chloride.
