The mitochondrial genome of a species is an essential resource for its effective conservation and phylogenetic studies. In this article, we present sequencing and characterization of the complete mitochondrial genome of a threatened labeonine fish, Cirrhinus reba collected from Khulna region of Bangladesh. The complete mitochondrial genome was 16,597 bp in size, which formed a circular double-stranded DNA molecule containing a total of 37 mitochondrial genes (13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes) with two non-coding regions, an origin of light strand replication (OL) and a displacement loop (D-loop), similar structure with other fishes of Teleostei. The phylogenetic tree demonstrated its close relationship with labeonine fishes. The complete mitogenome of Cirrhinus reba (GenBank no. MN862482) showed 99.96% identity to another haplotype of Cirrhinus reba (AP013325), followed by 90.18% identity with Labeo bata (AP011198).

BACKGROUND: Most of the people associated with tailoring occupation in Nepal are still using mechanical sewing machine as an alternative of new technology for tailoring. Common peroneal nerves of both right and left legs are exposed to strenuous and chronic stress exerted by vibration and paddling of mechanical sewing machine. METHODS: The study included 30 healthy male tailors and 30 healthy male individuals. Anthropometric variables as well as cardio respiratory variables were determined for each subject. Standard Nerve Conduction Techniques using constant measured distances were applied to evaluate common peroneal nerve (motor) in both legs of each individual. Data were analyzed and compared between study and control groups using Man Whitney U test setting the significance level p ≤ 0.05. RESULTS: Anthropometric and cardio respiratory variables were not significantly altered between the study and control groups. The Compound muscle action potential (CMAP) latency of common peroneal nerves of both right [(11.29 ± 1.25 vs. 10.03 ± 1.37), P < 0.001] and left [(11.28 ± 1.38 vs. 10.05 ± 1.37), P < 0.01] legs was found to be significantly prolonged in study group as compared to control group. The Amp-CMAP of common peroneal nerves of both right [(4.57 ± 1.21 vs. 6.22 ± 1.72), P < 0.001] and left [(4.31 ± 1.55 vs. 6.25 ± 1.70), P < 0.001] legs was found significantly reduced in study group as compared to control group. Similarly, the motor nerve conduction velocity (MNCV) of common peroneal nerves of both right [(43.72 ± 3.25 vs. 47.49 ± 4.17), P < 0.001] and left [(42.51 ± 3.82 vs. 46.76 ± 4.51), P < 0.001] legs was also found to be significantly reduced in study group in comparison to control group. CONCLUSION: Operating mechanical sewing machine by paddling chronically and arduously could have attributed to abnormal nerve conduction study parameters due to vibration effect of the machine on right and left common peroneal nerves. The results of present study follow the trend towards presymptomatic or asymptomatic neuropathy similar to subclinical neuropathy.

Introduction: Literature revealed that individuals with Autism Spectrum Disorders
(ASD) experience significantly more feeding problems and obesity compared to their
peers. This study was designed to investigate the nutritional status and dietary
patterns of children with autism in different age groups in Dhaka city, Bangladesh.
Methods: This cross-sectional study was conducted among 193 individuals with
ASD. A questionnaire was used as a tool to collect information from the mother of
the respondents and anthropometric assessments were conducted by measuring
height and weight. The dietary patterns of the respondents were taken using a
food frequency questionnaire. Results: The age range of the participants were
between 3-18 years. It was found that 11.9%, 19.7% and 23.3% of the participants
were underweight, overweight and obese, respectively according to Body Mass
Index (BMI)-for-age. About 70% of the respondents had medium Individual Dietary
Diversity Score (IDDS). In addition, the association between IDDS and obesity
was significantly correlated (p=0.00). Individuals with ASD exhibited similar food
preferences across most age groups with little changes. Conclusion: Our study
figured out that the prevalence of overweight increased in accordance with age
among children with ASD. They have a tendency to prefer likeness and routine
in their diet, which expands the tendency to have an imbalanced diet. A dietary
guideline including seven food groups should be followed to improve their nutritional
status and dietary practices.

Introduction: Cerebral palsy is a group of early childhood chronic mobility disorders. Parenting a child with cerebral
palsy is often challenging, especially for mothers. This research aimed to identify the determinants of the psychological
states of mothers of children with cerebral palsy in Bangladesh. Methods: A cross-sectional study was conducted
from December 2019 to February 2020. A total of 344 mothers of children with cerebral palsy was recruited using a
simple random sampling technique and guided questionnaires. The data were analysed using the Chi-square test and
logistic regression models. Results: The overall response rate was 98.29%. The median (IQR) age of respondents and
the children with cerebral palsy were 30 (13) and 6 (6), respectively. The proportions of mothers with good knowledge
on cerebral palsy and having higher negative family impact were 57.8% and 41.9%, respectively. Fifty-nine per
cent of mothers of children with cerebral palsy had higher levels of maternal psychological stress. The predictors of
maternal psychological stress were the mother’s age, marital status, types of family, family income, age of children,
gender, and higher levels of the negative maternal appraisal. Conclusions: Mothers of children with cerebral palsy
in Bangladesh had a higher level of maternal psychological stress. The factors identified in this study could help to
develop policies and strategies to minimise maternal psychological stress associated with parenting children with
cerebral palsy in Bangladeshi households.
