The bacterial profile and antibiotic susceptibility in skin and soft tissue infections at a tertiary care hospital of Quetta, Pakistan.

Objectives: To determine the bacterial profile and antibiotic susceptibility in skin and soft tissue infections among patients in a tertiary care setting. METHODS: The cross-sectional cohort study was conducted at the Centre for Advanced Studies in Vaccinology and Biotechnology, University of Balochistan, Quetta, Pakistan, from June 2021 to May 2022, and comprised bacteriainfected skin samples that were collected from the Bolan Medical Complex Hospital, Quetta, and the Sandeman Provincial Hospital, Quetta. The swab samples were immediately cultured, and positive samples were evaluated for biochemical tests, antibiotic susceptibility test and polymerase chain reaction. Data was analysed using SPSS 22. RESULTS: Of the 800 samples, 598(74.7%) tested positive for pathogenic bacteria. Staphylococcus aureus accounted for 316(39.5%) infections, followed by clostridium perfringens 18.96(2.37%), escherichia coli 120(15.12%), pseudomonas aeruginosa 98(12.25%) and klebsiella pneumoniae 44(5.5%). Among all the infected samples, 380(47.5%) belonged to males, 218(27.25%) to patients aged 5-20 years, 448(56%) to the uneducated subjects, and 462(57.87%) to patients having lower socioeconomic status. Pseudomonas aeruginosa showed the highest level of resistance against all antibiotics. Conclusion: Regular surveillance and proper use of antibiotics should be encouraged in hospitals to limit the spread of antibiotic resistance against pathogenic bacteria.

Depression and congestive heart failure: A large prospective cohort study from Pakistan.

OBJECTIVES: Evidence demonstrates the detrimental impact of depression in patients with congestive heart failure (CHF), however, large-scale prospective data from Low and Middle Income Countries (LMICs) is limited. We assessed the prevalence of depression in a large sample with CHF from Karachi, Pakistan, and the impact of depression on all-cause mortality, disability and health-related quality of life (QoL). METHODS: 1009 patients diagnosed with CHF were recruited from public hospitals in Karachi, Pakistan. Patients were screened for depression at baseline using the Beck Depression Inventory (BDI) and the diagnosis was confirmed using the Clinical Interview Schedule-Revised (CIS-R). Health-related QoL and disability were measured using the EuroQol (EQ-5D) and Brief Disability Questionnaire respectively at baseline and after a 6-month follow-up. RESULTS: A total of 670 (66%) patients were depressed at baseline and 821 participants completed 6-month follow up assessments (retention rate: 81%). At baseline, lower income (p < 0.001) and lower education level (p = 0.03) were associated with higher BDI scores. Higher BDI scores were associated with a history of depression (p < 0.001), higher NYHA class (p < 0.001), diabetes (p < 0.001), COPD (p = 0.007), renal disease (p < 0.001) and stroke (p = 0.02). 145 participants were deceased at 6-months. Regression analysis showed that at follow up, higher BDI scores in depressed participants were associated with higher all-cause mortality (OR 1.23 (95% CI: 1.11-1.36); p < 0.001). CONCLUSION: The rate of depression was high among Pakistani patients with CHF. Severity of depression correlated with increased mortality. Further research on controlled intervention trials in this population is warranted.
