Psychological impact of COVID -19 pandemic on frontline health care workers in Bangladesh: A cross-sectional study

This study aimed to estimate the prevalence of depression, anxiety, post-traumatic stress disorder, and insomnia symptoms among frontline health workers during the corona virus disease 19 (COVID-19) pandemic in Bangladesh and to compare these between medical and allied health workers. We conducted a cross-sectional survey between June and August 2020. A total of 479 health care professionals participated in the study. Anxiety and depression were measured using Patient Health Questionnaire-4 (PHQ-4), post-traumatic stress disorder (PTSD) was measured by primary care post-traumatic stress disorder score (PC-PTSD score), and insomnia was measured by Insomnia Severity Index (ISI). We performed logistic regression to assess risk factors associated with psychological symptoms. Overall, prevalence of anxiety, depression, PTSD and insomnia symptoms were 17.6%, 15.5%, 7.6% and 5.9%, respectively. Compared to allied health workers, doctors had significantly higher prevalence of symptoms of anxiety: doctor versus allied health care worker; 21.1% vs 06%, (OR= 4.19; 95% CI= 1.88-9.35; p <0.001); depression: 18% vs 6.8%, (OR= 2.99; 95% CI= 1.40-6.42; p 0.005); PTSD: 9.4% vs 1.7%, (OR= 5.96; 95% CI= 1.41-25.11; p 0.015) and insomnia: 7.4% vs 0.9%, (OR= 9.22; 95% CI= 1.24-68.4; p 0.03),respectively. The logistic regression analysis showed pre-existing medical illness as a predictor of anxiety (OR= 2.85; 95% CI= 1.71-4.76; p <0.001) and depressive symptoms (OR= 2.29; 95% CI= 1.39-3.77; p 0.001). Working more than 6(six) weeks in COVID-19 dedicated hospitals was significantly associated with PSTD symptoms (OR= 2.83; 95% CI= 1.35-5.93; p 0.006) and insomnia (OR= 2.63; 95% CI= 1.15-6.02; p 0.022). Our study demonstrated a high prevalence of symptoms of depression, anxiety, PTSD, and insomnia among Bangladeshi frontline health workers during the COVID-19 pandemic.

Presenting features of locally advanced breast cancer : a crosssectional study

Worldwide, breast cancer is the most frequently diagnosed life-threatening cancer in women. This cross sectional study was done to assess the presenting features of locally advanced breast cancer. The mean age was 42.6 years with standard deviation 9.56, 86% were house wife, 53.5% were illiterate, 16% were postmenopausal and 75.8% had BMI of 20Kg/m2. Ninety one point five percent had menarche at or above 12 years of age and 26.6 % had history of using hormonal contraceptives. Tobacco user and positive family history were found in 21.2% and 5.35% of the cases. 84% were presented with only lump and 16% with both lump and ulceration. Right breast was involved in 51.1%. About 37% cases presented on 3rd month of their symptoms. Around 71.2% patients presented with lump >5cm in diameter, axillary lymph nodes were palpable in 81% and fixed in 31% of patients. Around Sixty three percent of patients were in stage IIIA. Still a large fraction of patients present with advanced stage with varied presentation, sometimes surgeons face difficulties to offer the treatment. Proper awareness, early presentation and early detection give them the opportunity to receive the best treatment. BSMMU J 2021; 14(4): 148-15

Accelerated generation of elite inbreds in maize using doubled haploid technology

The creation of homozygous parental lines for hybrid development is one of the key components of commercial maize breeding programs. It usually takes up to 6 to 7 generations of selfing to obtain homozygous inbreds from the initial cross using the conventional pedigree method. Using doubled haploid (DH) method, concurrent fixation of all the genes covering entire chromosomes is possible within a single generation. For generation of DH lines, haploids are generated first by several means such as in-vitro method using tissue culture technique and in-vivo method using the haploid inducer (HI) lines. Of which, tissue culture-based methods have shown little promise for large-scale DH production as it needs good infrastructures and technical requirements. In contrast, inducer-based method provides more optimistic solutions for large-scale DH lines production. Due to its rapidity, DH technology is now being adopted in many countries including India for reducing the breeding cycle

Consequences of Thumb Sucking Habit among School Going Children: A Cross Sectional Study

Background: Thumb-sucking, a non-nutritive sucking behavior, is a natural reflex seen in infants but can persist into childhood if not addressed leading to various dental and orofacial issues, including malocclusion, dental arch deformities, speech difficulties, and facial asymmetry. The aim of the study was to explore the consequences of thumb-sucking habits among the school going children. Methods: This cross-sectional study involved among purposively selected 124 school going children, aged between 5-8 years with their parents attended in the outpatient department of University Dental College at Moghbazar, Dhaka, Bangladesh. The data were obtained through a pretested structured questionnaire and checklist through face-to-face interview from parents regarding background characteristics, consequences of thumbs sucking and oral examination of children respectively. Then, data were analyzed using statistical package for social sciences (SPSS) software version 27 for descriptive analysis (frequency, percentage) and inferential statistics (chi-square test or fisher’s exact test) at 5% level of significance (P<0.05). Results: The study revealed that 77.4% of children aged 5-6 years and about 41.9% of parents reported that their child had thumb sucking habit. The thumb sucking habit was found to be statistically significant with start of age thumb sucking( p= <0.001), duration of thumb sucking ( p= <0.001), pronunciation of word clearly( p= <0.001), proclination of maxillary anterior teeth (P=0.002), asymmetry of face (P=0.002) and seek for dental advice or treatment(p=0.002). Majority of children (21.8%) start thumb sucking at the age 6-7 years. Only 8.1% of the children didn’t pronounce words clearly whereas only 5.6% had proclined maxillary anterior teeth, facial asymmetry and sought dental advice or treatment. Conclusion: This study found a significant association of thumb-sucking habit among children with notable consequences. It highlights the importance of early intervention and parental education and awareness regarding this habit's potential consequences on children's oral health and overall development

Lagrangian evolution of velocity increments in rotating turbulence: The effects of rotation on non-Gaussian statistics

The effects of rotation on the evolution of non-Gaussian statistics of velocity increments in rotating turbulence are studied in this paper. Following the Lagrangian evolution of the velocity increments over a fixed distance on an evolving material element, we derive a set of equations for the increments which provides a closed representation for the nonlinear interaction between the increments and the Coriolis force. Applying a restricted-Euler-type closure to the system, we obtain a system of ordinary differential equations which retains the effects of nonlinear interaction between the velocity increments and the Coriolis force. A priori tests using direct numerical simulation data show that the system captures the important dynamics of rotating turbulence. The system is integrated numerically starting from Gaussian initial data. It is shown that the system qualitatively reproduces a number of observations in rotating turbulence. The statistics of the velocity increments tend to Gaussian when strong rotation is imposed. The negative skewness in the longitudinal velocity increments is weakened by rotation. The model also predicts that the transverse velocity increment in the plane perpendicular to the rotation axis will have positive skewness, and that the skewness will depend on the Rossby number in a non-monotonic way. Based on the system, we identify the dynamical mechanisms leading to the observations. (c) 2010 Elsevier B.V. All rights reserved
