Male factors contribute significantly, comprising 40.0% to 50.0% of infertility cases. While the prevalence ranges from 5.0% to 30.0% in developing countries, the exact global prevalence remains unknown. The study, conducted at CMH and Ibn Sina Hospital, Jashore from October 2020 to September 2023, utilized a cross-sectional approach; examining 4173 samples aged 21 to 41. Exclusion criteria considered known female reproductive abnormalities or medications impacting male fertility. Standardized procedures, in-depth questionnaires and SPSS software version 15.0 were employed, adhering to World Health Organization Guidelines. In a study of 4173 seeking infertility treatment, 63.0% had abnormal semen parameters, with 45.0% aged 31-40 years. Addiction patterns: 76.0% used tobacco, 14.0% reported alcohol and tobacco. Occupations: 43.0% government workers, 41.0% private workers. Marriage duration: 44.0% married 5-10 years, infertility duration: 64.0% less than 6 years. Semen analysis showed 40% with sperm count above 65 million, 46.0% with 60.0-90.0% motile sperm, and 78.0% with sperm morphology below 15.0%. The most prevalent abnormality is asthenozoospermia 59%, with oligozoospermia and azoospermia observed in 31% and 3% of cases, respectively.

Patients experience many different symptoms including severe pain in advanced cancer. Palliative care focuses on relief from symptoms, pain and stress by using different analgesics and adjuvant. The goal of palliative care is to improve the quality of life. So, this prospective observational study was carried out to assess pattern of drugs used and their response to pain in cancer patients attending out-patient department of palliative care service in two teaching hospitals of Bangladesh. One hundred forty (140) cancer patients were purposively selected who attended in out-patient department of palliative care unit in Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College Hospital (DMCH) from July 2018 to June 2019. Outcome variables were commonly presenting complaints, pain intensity, commonly prescribed drugs and analgesic prescription according to WHO three-step analgesic ladder, etc. The mean age ±SD of the respondents was 51.30±15.38 years, male-female ratio 1:1. Common sites of cancer were alimentary origin (20.0%), genitourinary system (17.86%), hepatobiliary system (11.43%), respiratory system (10.71%).

The relation between and receiving three levels of analgesic prescriptions was statistically significant. The association between level of analgesic prescription was significant with site of cancer (p<0.001) and intensity of pain (p<0.001).

This retrospective study recruited 208 RT-PCR positive Covid-19 patients from 1st April 2020 to 15th May 2020 who appeared at Flu corner centre, 250 Bedded General Hospital, Jashore, Bangladesh. Data was collected online through telephone, mobile and email due to the high contagious property of Covid-19.

About 80% of patients are found between 50 to 80 years of age. It is 3-4 times more common in male than in female. Determination of therapeutic strategy and prediction of progression of urothelial carcinoma is a major clinical challenge. Treatment of urothelial carcinoma still now mostly depends on pathological stages. Amplification or genomic alteration of Cyclin D1 (a proto-oncogene) may cause protein overexpression which is frequently realized as a clonal pathology in various human neoplasms including bladder cancer. Evaluation of Cyclin D1 expression is promising for guiding therapeutic strategies, risk stratification and prediction of tumor progression.
