Background: Hospital-acquired infections (HAIs) caused by multidrug resistant (MDR) bacteria are a major public health problem especially in resource-limited settings. Local data on antimicrobial resistance (AMR) are crucial to inform empirical therapy and infection prevention. Objectives: To identify bacterial pathogens causing HAIs, determine their AMR profiles and independent risk factors for MDR infections in a tertiary hospital in Erbil City, Iraq. Materials and Methods: A cross-sectional study was done at Hawler Teaching Hospital between January and June 2026. Standard microbiological methods were used to analyse 200 clinical specimens from patients with HAIs (≥48 hr after admission). Antimicrobial susceptibility testing was performed according to CLSI 2024 guidelines. MDR was defined as nonsusceptibility to at least one agent in three or more antimicrobial classes. Multivariate logistic regression was used to assess independent risk factors. Results: Bacterial growth was obtained in 149 of 200 specimens (74.5%). The major pathogens were Escherichia coli (31.5%), Klebsiella pneumoniae (23.5%), Staphylococcus aureus (21.5%), Pseudomonas aeruginosa (14.1%) and Acinetobacter baumannii (6.1%). In total, 69.1% of the isolates were MDR, with the highest rates in K. pneumoniae (80.0%) and A. baumannii (77.8%). Independent predictors of MDR infection were previous antibiotic use (AOR=4.45), ICU admission (AOR=3.92), and hospitalization >7 days (AOR=3.10). Conclusion: This study documented a significant burden of MDR-HAIs in Erbil City and determined modifiable clinical risk factors. The findings provide evidence to support antimicrobial stewardship, infection prevention and AMR surveillance in Iraqi healthcare settings.

Background: Tuberculosis (TB) in the elderly poses significant diagnostic and therapeutic challenges due to immunosenescence, comorbidities, and atypical clinical presentation. This study evaluates the epidemiological and clinical characteristics of TB in patients aged ≥65 years. Methods: A retrospective descriptive study was conducted including all TB cases reported between 2020 and 2024. Data from the National Tuberculosis Program were analyzed for demographic characteristics, clinical form, bacteriological confirmation, comorbidities, and treatment outcomes. Results: Of 1,335 TB cases, 352 (26.4%) occurred in individuals aged ≥65 years. Pulmonary TB accounted for 80.7% of cases. Men represented 63.4% of patients, and 56.8% lived in urban areas. Bacteriological confirmation was achieved in 82% of pulmonary cases, and treatment success exceeded 85%. Diabetes mellitus (26.5%) and arterial hypertension (31%) were the most common comorbidities. An increase in TB cases was observed in the post-COVID-19 period. A significant association was found between age and clinical form of TB (p < 0.001). Conclusions: Elderly individuals constitute a substantial proportion of TB cases and frequently present with chronic comorbidities. Despite diagnostic challenges, favorable treatment outcomes were achieved, highlighting the need for integrated and early management strategies in this population.

Background: Vitamin D plays an important role in the development of bone health and possibly non-communicable diseases. Arab countries had made their own national studies to assess serum vitamin D level among women, yet in Egypt there is no national survey done. The aim of the current study was to identify risk factors affecting vitamin D level among Egyptian females during the child-bearing period. Subjects and methods: A total of 100 healthy adult females in their childbearing period who were attending a Family Medicine Center were included in our study. The age of the included women ranged from 19 to 49 years old with a mean age of 34 (SD 8.47) years. The majority of participants had deficiency (43%) and insufficiency (13%) of vitamin D level. Results: Unemployed women were more likely to have vitamin D deficiency than employed women (P<0.05). Participants who were exposed to sun ˃30 minutes/day were more likely to have sufficient vitamin D level (P<0.05). All participants who consume fish ≥3 times/week had sufficient vitamin D level. Therefore, there was a statistically significance association between a number of consuming fish/week and vitamin D3 level groups. Also, there was statistically significant association between number of consumed milk cups/day and vitamin D3 level groups. All participants who drink 2 cups of milk have sufficient vitamin D level. No statistically significance association was found between using multivitamins and vitamin D3 level groups. Conclusion: Unemployment, low fish consumption and infrequent sun exposure were significant risk factors for vitamin D deficiency. Future research on the role of multivitamins supplements in improving vitamin D nutrition is warranted.
