Urinary incontinence is a common complaint of both general practitioners and specialists. An accurate basic diagnosis with a structured medical history and bladder diary, urine analysis, gynaecological examination including pelvic floor assessment and a full bladder cough test can be supplemented by sonography, cystoscopy and urodynamic testing. This will help to differentiate between the different types of urinary incontinence, such as urge incontinence, stress incontinence and overflow incontinence.

Background: Sustaining a 'fit-for-purpose' health workforce requires a better understanding of the health care worker cadres that are affected during pandemics and their outcomes. In hospitalized health care workers with confirmed COVID-19 between March 2020 and May 2023 in Liberia, we determined the hospitalization and case fatality rates, type of health care worker cadres affected, their demographic and clinical characteristics and hospital exit outcomes.

Methods: This was a cohort study using routine data extracted from hospitalization forms for health care workers in 24 designated COVID-19 treatment facilities.

Background: We examined the feasibility of assessing and referring adults successfully completing TB treatment for comorbidities, risk determinants and disability in health facilities in Kenya, Uganda, Zambia and Zimbabwe.

Methods: This was a cross-sectional study within national TB programmes.

Results: Health workers assessed 1,063 patients (78% of eligible) in a median of 22 min [IQR 16-35] and found it useful and feasible to accomplish in addition to other responsibilities.

Background: The study assessed whether a "7-1-7" timeliness metric for screening and TB preventive therapy (TPT) could be implemented for household contacts (HHCs) of index patients with bacteriologically confirmed pulmonary TB under routine programmatic settings in Kenya.

Methods: A longitudinal cohort study conducted among index patients and their HHCs in 12 health facilities, Kiambu County, Kenya.

Results: Between January and June 2023, 95% of 508 index patients had their HHCs line-listed within 7 days of initiating anti-TB treatment ("First 7").

BACKGROUNDAlthough screening of household contacts (HHCs) of TB patients and provision of TB preventive therapy (TPT) is a key intervention to end the TB epidemic, their implementation globally is dismal. We assessed whether introducing a '7-1-7' timeliness metric was workable for implementing HHC screening among index patients with pulmonary TB diagnosed by private providers in Chennai, India, between November 2022 and March 2023.METHODSThis was an explanatory mixed-methods study (quantitative-cohort and qualitative-descriptive).

Article Synopsis
  • The study investigates the rate of obstetric anal sphincter injuries among first-time mothers (primiparae) delivering in water vs. on a bed.
  • Nearly 4,000 primiparae were analyzed, revealing that 4.94% experienced such injuries, with a lower rate (3.7%) in water deliveries compared to bed deliveries (6.1%).
  • Subgroup analysis indicated that using oxytocin during labor was associated with lower injury rates in water births, highlighting the benefits of water delivery in reducing these injuries.

Introduction: Screening household contacts of TB patients and providing TB preventive therapy (TPT) is a key intervention to end the TB epidemic. Global and timely implementation of TPT in household contacts, however, is dismal. We adapted the 7-1-7 timeliness metric designed to evaluate and respond to infectious disease outbreaks or pandemics, and assessed the feasibility, enablers and challenges of implementing this metric for screening and management of household contacts of index patients with bacteriologically-confirmed pulmonary TB in Karachi city, Pakistan.

The quality of pharmacovigilance data is important for guiding medicine safety and clinical practice. In baseline and follow-up studies after introducing interventions to improve the quality of reporting of Individual Case Safety Reports (ICSRs) in Sierra Leone, we compared (a) timeliness and completeness of reporting and (b) patient outcomes classified as 'recovering'. : Baseline (January 2017-December 2021) and follow-up (June 2022-April 2023) studies of ICSRs in the national pharmacovigilance database.

(1) : Surgical antibiotic prophylaxis (SAP) is important for reducing surgical site infections. The development of a dedicated hospital SAP guideline in the Dhulikhel Hospital was a recommendation from a baseline study on SAP compliance. Compliance with this new guideline was enhanced through the establishment of a hospital committee, the establishment of an antibiotic stewardship program and the funding and training of healthcare professionals.

Many patients with tuberculosis (TB) have comorbidities, risk determinants and disability that co-exist at diagnosis, during and after TB treatment. We conducted an observational cohort study in 11 health facilities in China to assess under routine program conditions (i) the burden of these problems at the start and end of TB treatment and (ii) whether referral mechanisms for further care were functional. There were 603 patients registered with drug-susceptible TB who started TB treatment: 84% were symptomatic, 14% had diabetes, 14% had high blood pressure, 19% smoked cigarettes, 10% drank excess alcohol and in 45% the 6 min walking test (6MWT) was abnormal.

Background: Gliomas are frequent tumors of brain parenchyma, which have histology similar to that of glial cells. Accurate glioma grading is required for determining clinical management. The background of this study is to investigate the accuracy of magnetic resonance imaging (MRI)-based radiomic features extracted from multiple MRI sequences in differentiating low and high-grade gliomas.

Objective: This study aimed to determine the performance of infection prevention and control (IPC) programs in eight core components in level 2 and level 3 hospitals across all provinces in Colombia.

Methods: This cross-sectional study used self-assessed IPC performance data voluntarily reported by hospitals to the Ministry of Health and Social Protection during 2021. Each of the eight core components of the World Health Organization's checklist in the Infection Prevention and Control Assessment Framework contributes a maximum score of 100, and the overall IPC performance score is the sum of these component scores.
