There is mounting evidence that Facebook Addiction is associated with poor mental health, physical symptoms, social dysfunction, and despair among the adolescent and youth population. The current study set out to identify the prevalence of Facebook Addiction among Bangladeshi medical students as well as its influencing factors. This cross-sectional survey was conducted on 720 randomly selected medical students from eight public medical colleges from January to June 2022. Data were obtained using a semi- structured, self-reported questionnaire and analyzed using the SPSS v.23 programs. The Bergen Facebook Addiction Scale BFAS was used to assess Facebook Addiction, while the Generalized Anxiety Disorder GAD-7, Patient Health Questionnaire PHQ-9, Perceived Stress Scale PSS10, Chen Internet Addiction Scale CIAS, and Pittsburg Sleep Quality Index PSQI was used to assess anxiety, depression, perceived stress, internet addiction, and sleep quality. Binary logistic regression was used to evaluate the influence of several demographic, psychological, and behavioral characteristics on the likelihood of respondents being addicted to Facebook. Facebook Addiction was observed in 29.4% of medical students. According to data, 63.7% of medical students reported mild to severe anxiety, 29.3% moderate to severe depression, and 84.9% moderate to high perceived stress. Lack of personal income [OR with (95% CI), 1.82 (1.13, 2.96)], poor academic performance [2.46 (1.45, 4.15)], moderate anxiety [2.45 (1.22, 4.92)], moderate perceived stress [5.87 (1.92, 17.95)], and moderately severe depression [2.62 (.97, 7.08)] were all found to play a significant role in the development of Facebook Addiction. However, living with parents [OR with (95% CI), .37 (.14, .95)] and positive family relationships [.40 (.18, .87)] reduces the likelihood of becoming addicted to Facebook. An integrated participative Behavioral and psychological intervention should be devised to reduce the risks of Facebook addiction in medical students while also improving their mental health-related quality of life.

The prevalence of prostatic carcinoma is the outcome of several factors including improved awareness the general population of the significance of carcinoma of the prostate and progresses in diagnostic approaches. The PSA is a probable prostate cancer tumor marker, although it cannot distinguish prostate cancer from BPH solely. To assess the usefulness of free, total, and free/total PSA ratios in differentiating BPH and prostate cancer has been studied under this research work. The work was carried out at RMCH during April 2021 to March 2022, 350 purposively selected urology outpatients and inpatients at RMCH were studied cross-sectional study. Trans-rectal ultrasound (TRUS) and serum PSA levels were analyzed along with Digital rectal examination (DRE). A digital guided prostatic biopsy using a monopty biopsy gun confirmed the diagnosis. Data analysis was done in SPSS 26 software program. Prostatic cancer was more prevalent in men aged 70-80, whereas BPH was more common in men aged 60-70 (p = 0.00032). Histopathology revealed 95 prostate cancer patients, 82 with PSA >4 ng/ml and 85 patients had f/t PSA ratio>0.16. BPH was found in 255 individuals. 139 BPH patients had total PSA >4 ng/ml and 245 BPH patients had f/t PSA ratio ≤0.16. Total PSA had sensitivity and specificity of 86.32% and 45.49%, respectively, lower than f/t ratio. The (Positive predictive value) PPV and accuracy was significantly higher in f/t ratio than total PSA. Along with total PSA, free and free/total PSA ratio may help detect prostate cancer early and distinguish BPH from prostate cancer. J Bio-Sci. 30(1): 79-89, 2022 (June)

Introduction: Menstruation-related poor knowledge and understanding among adolescent girls may lead to unsafe personal health care practice that ultimately increases the risk of genito-urinary tract infections, drop-out from school, poor academic performance, and overall poor quality of life. Being a developing country, it is an unrecognized problematic area in Bangladesh. Therefore, it is crucial to assess knowledge and practice on menstrual hygiene among urban adolescent girls in Bangladesh. Methods: This was a community-based cross-sectional study conducted in the Department of Community Medicine of Rajshahi Medical College among 495 purposively selected urban adolescent girls. Data were collected using a semi-structured interviewer-administered questionnaire. Results: The majority (57.2%) of the respondents in the study were more than 15 years old, and most (93.3%) were Muslim. Most of the girls (82.5%) have experienced menarche within the age range of 12-15 years, and the majority of respondents, 259 (52.32%), were informed about menstruation before menarche. Their source of information about menarche was mothers in most cases. Out of 495 adolescent girls who participated in this study, 70.9% had good knowledge of menstruation. About 82% of girls used commercially made sanitary pads, and 35.2% changed pads or clothes more than three times a day during menstruation. Conclusion: The majority (70.9%) of adolescent girls had good knowledge of menstruation, and 73.3% had a good practice on menstrual hygiene. Therefore, there is a need to design and implement universal awareness creation and advocacy programs to improve their knowledge of safe and healthy menstruation management and promote good hygienic practices by creating an appropriate supportive home and social environment for all the adolescent girls.
