Objectives: To investigate SARS-CoV-2 associated epidemiology and clinical outcomes in Bangladesh to understand the course of COVID-19 pandemic and suggest prevention measures.
Methods: A cross-sectional retrospective study was conducted among 1,021 RT-PCR confirmed but recovered COVID-19 cases from six participating hospitals in Bangladesh.
Results: Of the total sample, 111 (10.9%) cases were asymptomatic while the number of symptomatic cases were 910 (89.1%). Higher prevalence of COVID-19 persisted in the male population (75%) and for the 31-40 age group. More than 85% of the samples reported BCG vaccination mark. Common symptoms observed in our study samples were fever (72.4%), cough (55.9%), loss of taste (40.7%) and body ache (40%); whereas for the biochemical parameters, Neutrophil (46.4%), D-dimer (46.1%), Ferritin (37.9%) and SGPT (36.8%) levels were found elevated. Post-COVID complications including pain (31.8%), loss of concentration (24.4%) and anxiety or depression (23.1%) were found significantly prevalent.
Conclusion: Our study has shown that adult males aged between 31-40 in Bangladesh are more vulnerable to being infected with COVID-19. With an indication for the rising trend of the asymptomatic cases, deployment of interventions to curb further community spread is necessary to avoid the grave outcomes of COVID-19 in Bangladesh.
Diversity of aquatic insects in relation to the physicochemical parameters of the river Buriganga and Shitalakhya were studied from January to December 2013. A total of 9,891 individuals of aquatic insects representing 22 families under 6 orders were collected and identified. Higher number of insects were recorded from the river Shitalakhya (5,493) than the river Buriganga (4,398). Representatives of the family Culicidae were found to be dominant in the river Buriganga (23.28%) than Shitalakhya (20.70%). Specimens under the order Ephemeroptera and Trichoptera were found only in the river Shitalakhya. The highest diversity of Shannon Weiner Index (2.98), Evenness (0.98) and Taxa Richness (0.98) were recorded in the river Shitalakhya than the river Buriganga. This indicated the less pollution and presence of higher diversity of aquatic insects in the Shitalakhya river. The highest temperature, pH, EC, TDS, COD was observed in Buriganga in dry season and highest DO was observed in Shitalakhya in monsoon. From the present investigation it may be concluded here that the river Buriganga was more polluted than the river Shitalakhya.
Background: The rupture of fetal membrane before onset of labour at less than 37 completed weeks of gestation. Incidence of Preterm prelabour rupture of membrane (PPROM) ranges from 3.0-10.0% of all deliveries and causes around 25-30% of all preterm deliveries.
Objective: To see the clinical profile, maternal and fetal outcome of preterm prelabour rupture of the membrane.
Materials and Methods: One hundred fifteen pregnant women with 28-37 weeks of gestation and diagnosed as PPROM admitted in different units selected by purposive sampling, fulfilled the inclusion and exclusion criteria were enrolled as study population in this study.
Results: The mean age was 24.65(±3.68) years. Majority (75.65%) were primi para. The mean gestational age was 32.34(±2.86) weeks, 79.13% had gestational age between 30-36 weeks and 20.87% had up to 30 wks. The common risk factors of the study population were history of coitus, CPD, infection and history of abortion which were 42.61%, 9.57%, 5.22% and 4.35% respectively. Majority 55.65% women had vaginal delivery, 44.35% had caesarian section. Majority of the babies born to PPROM group were in the very low birth weight category (53 cases 62.3%), whereas only 32 cases (37.6%) were of normal birth weight. Infection and perinatal mortality was significantly associated with PPROM.
Conclusion: PPROM can be prevented avoiding the certain risk factors by proper ante natal checkup, strict follow up, good obstetrical care and perinatal care , making mass awareness of the sequele.
