Perception of Prevalence, Complications and Associated Factors of Diabetes in an Urbanizing Rural Community of Bangladesh Sani, Deedarul Hyder The pandemic of diabetes is more explosive in developing countries due to fast expanding urbanization and way of life change. The aim of this study was to investigate the diabetes prevalence and complications while examining the relationship between socio-demographic factors, clinical factors, and glycemic control in an urbanizing rural community. An observational, non-interventional, cross-sectional design was used for this study. This observational study was conducted in an urbanizing rural area of Cumilla district. Potential predictor variables including lifestyle, BMI, dietary pattern, age, diabetes duration, and frequency of self-monitoring were analyzed for their relationship with various complications as well as collection of information regarding risk factors and socio-demographic variables. Patients’ non-adherence to self-care practices & medications were also assessed. A total of 100 patients (male:37; female:63) with mean age 54.39±13.13 years participated in the study. The majority of the study participants (52%) were from the upper lower family and 75% of the patients had a family history of diabetes. Around 60% of study patients had been taking polytherapy treatment and the use of Metformin (27%) and insulin (26%) was mostly observed. The most common diabetes-related complications among the study subjects were: diabetic retinopathy (70%) and peripheral neuropathy (64%) and hypertension (61%). The maximum non-adherence rate among diabetic patients was found in foot care (63%), exercise (48%), diet (47%). Lifestyle (p<0.01), diet (p<0.05), duration of diabetes (p<0.05) had a significant association with fasting blood glucose (FBG) level of the study patients. Knowledge of the prevalence of diabetes and related risk factors could raise awareness of the disease. The present data could be used in developing fruitful intervention program for diabetes patients and in improving their quality of life.

A Cross-sectional Study on Knowledge, Practices and Economic Conditions Associated with COVID-19among the Rural Population in Pabna District of Bangladesh Islam, Md. Muzahidul The current pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-cov-2) has presented unprecedented challenges to the healthcare systems in almost every country around the world, especially in Bangladesh due to lack of proper education and other socio-demographic factors. The best way to prevent the wrath of this virus is to understand the sociodemographic factors which are responsible for the poor knowledge, practice and economic condition due to COVID-19 pandemic in rural area. Therefore, a cross-sectional study was conducted in rural areas of Pabna district to observe and understand the knowledge and practice regarding COVID-19. Since worldwide economics has collapsed due to COVID-19, its impact was also evaluated to observe the business changes of rural citizens. Data was collected from 1000 participants with their consent. Among them, 43.8% respondents kept good knowledge regarding COVID-19. Despite good knowledge, practices were significantly lower among married, uneducated, day-laborer, since most of them struggle daily for hand-to-mouth. The mean scores of KP were 6.04±2.93 (out of 11) and 1.91±1.469 (out of 8) respectively. This result suggested that practices were poor though people had good knowledge on COVID-19. KP were significantly diverged across age, gender, education levels, religious status, residences, and marital status. Data analysis from this survey revealed that farmers and businessmen of Pabna district were the worst sufferer in this pandemic. Government and policy makers should consider these knowledge levels, practices and business changes to implement productive interventions for preventing the worst condition of COVID19.

Relationship between Insulin Sensitivity and Lipid Status of Hyperglycemic and Normoglycemic Subjects Malik, Syeda Umme Fahmida Type 2 diabetes mellitus (T2DM) is primarily due to a decreased response to insulin in the tissues of the body, which is defined as the insulin resistance (IR). Excess weight, obesity and morbid obesity are all risk factors for developing T2DM. The usual characteristics of South Asians include low muscle mass, a high body fat percentage, abdominal obesity, insulin resistance, and hyperinsulinemia. Type 2 diabetes is among the most serious consequences of being overweight or obese. The risk factors for cardiovascular illnesses in obese people are insulin resistance (IR) and abnormal lipid profiles. To investigate the relationship among IR, obesity and lipid profile, this study was conducted on a total of 1500 Bangladeshi people at the time of their general health checkup in the North East Medical College Hospital. The Ethical Committee of North East Medical College Hospital approved this study. All the T2DM patients were defined according to the 1999 World Health Organization (WHO) criteria and randomly recruited from the outpatient department. The controls had a fasting plasma glucose concentration <5.1 mmol/L and HbA1C <6%, with no history of oral hypoglycemic or lipid lowering agents. We collected the medical history and demographic information of all the individuals. Total study population was grouped according to age, gender, insulin, glycemic status and obesity. However, 728 patients were excluded due to other endocrine diseases. The remaining 772 patients were categorized as having IR > 2 and IR< 2 based on the homeostatic model assessment-estimated insulin resistance (HOMA-IR) index. Statistical analysis was used to examine and link the anthropometric and biochemical profiles with the IR>2 and IR<2 groups. In comparison to the IR<2 group, the total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), and serum insulin levels were considerably higher in all the IR>2 group. Obesity and dyslipidemia were found to be common IR components. According to a generalized linear model, IR was significantly impacted by TC:LDL and TG:HDL. In comparison to age groups I (20–40 years old) and III (61-80 years old), participants in the age group II (41–60 years old) showed considerably higher lipid profiles. These findings provide credence to the idea that lipoprotein ratios may serve as biomarkers for measuring IR. During this study period, novel corona virus affected different people in different regions worldwide. The COVID-19 patients with DM more likely exhibited severe inflammatory response. In an effort to comprehend the connection between COVID-19 and diabetes mellitus and to assess the most affordable treatment option for the general population, the medical data of all suspected patients from 1 May 2020 to 15 August 2020 in the Medical College and Hospital aforementioned were included in the study. A total of 250 suspected COVID-19 patients were considered for this study. Among them, 211 patients were reviewed for laboratory data availability. Most of these patients had mild v symptoms and a good prognosis. All of the 211 patients were subjected to test for COVID-19 confirmation by qRT-PCR. Among them, 98 patients were confirmed COVID-19 positive. Several blood biomarkers in T2DM and non-diabetic (NDM) COVID-19 positive patients were analyzed to rapidly predict COVID-19 progression and severity. In the serum of COVID-19 patients, substantial amounts of ferritin, C-reactive protein (CRP), D-dimer, ALT, and troponin I. In comparison to COVID-19 positive patients without diabetes, the COVID- 19 patients with T2DM had increased levels of HbA1C, serum ferritin, and CRP. Data in the present study support the notion that ferritin and HbA1c levels for DM patients, and ferritin, D-dimer, ALT for NDM patients could be biomarkers for progression and severity assessment of COVID-19. However, CRP and Troponin-I could be biomarkers only for poor prognosis of COVID-19. Insulin receptor is a big warehouse of diseases such as T2DM. Any change or mutation in insulin receptor (INSR) may change disease pathogenesis. Single nucleotide polymorphisms (SNPs) may fall within coding sequences of genes (Non- synonymous), non-coding regions of genes (synonymous), or in the intergenic regions between genes. Non-synonymous SNPs (nsSNPs) may have deleterious effect due to substitution of single amino acids in the protein sequence. The harmful nsSNPs in the INSR gene was analyzed based on various computational approaches. The computational analysis indicated that 13 of these mutations nsSNPs decreased protein stability and may have led to function loss. Two nsSNPs such as I448T and W1220L positions (rs1051691 and rs52800171, respectively) were predicted as "Highly Destabilizing”. Their inclusion in the INSR raises the risk of diseases caused by the INSR and altered transcriptional and cell cycle control. In order to search SNPs in the INSR in Bangladeshi subjects, genomic DNA were isolated from healthy individuals and T2DM patient for sequences analysis. Polymerase chain reaction was carried out with primers from different exons of the INSR. Sequence analysis showed that Bangladeshi diabetic patients included in the present study had two mutations in exon 11 of the INSR. However, no mutation was observed in the healthy individuals. The 3D model analysis using bioinformatics tools revealed that the both mutations in the exon 11 may cause conformational change in the INSR. These alterations in the INSR could either slow or speed up the disease's course.
