Background: MDR-TB is a major threat to global TB control. In 2015, 580,000 were treated for MDR-TB worldwide. The worldwide roll-out of GeneXpert MTB/RIF has improved diagnosis of MDR-TB; however, in many countries laboratories are unable to assess drug resistance and clinical predictors of MDR-TB could help target suspected patients. In this study, we aimed to determine the clinical factors associated with MDR-TB in Bamako, Mali.
Methods: We performed a cross-sectional study of 214 patients with presumed MDR-TB admitted to University of Bamako Teaching Hospital, Point-G between 2007 and 2016. We calculated crude and adjusted odds ratios for MDR-TB disease diagnosis using SPSS.
Results: We found that age ≤40years (OR=2.56. 95% CI: 1.44-4.55), two courses of prior TB treatment (OR=3.25, 95% CI: 1.44-7.30), TB treatment failure (OR=3.82, 95% CI 1.82-7.79), sputum microscopy with 3+ bacilli load (OR=1.98, 95% CI: 1.13-3.48) and a history of contact with a TB patient (OR=2.48, 95% CI: 1.11-5.50) were significantly associated with confirmation of MDR-TB disease. HIV was not a risk factor for MDR-TB (aOR=0.88, 95% CI: 0.34-1.94).
Conclusion: We identified several risk factors that could be used to identify MDR-TB suspects and prioritize them for laboratory confirmation. Prospective studies are needed to understand factors associated with TB incidence and clinical outcomes of TB treatment and disease.

Heterogeneity of Apolipoprotein B Levels Among Hispanic or Latino Individuals Residing in the US.
JAMA Cardiol
January 2025
Cardiology Division, Department of Medicine, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, New York.
Importance: Apolipoprotein B (apoB) distribution and its implications as an atherosclerotic cardiovascular disease (ASCVD) risk-enhancing factor among individuals of diverse Hispanic or Latino backgrounds have not been described.
Objective: To describe the distribution of apoB in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort and to characterize associations of baseline sociodemographic and clinical variables with apoB and self-identified Hispanic or Latino background.
Design, Setting, And Participants: The HCHS/SOL was a prospective, population-based cohort study of diverse Hispanic or Latino adults living in the US who were recruited and screened between March 2008 and June 2011.
De-Escalation of Nodal Surgery in Clinically Node-Positive Breast Cancer.
JAMA Surg
January 2025
Breast Unit, Department of General Surgery, Istanbul Faculty of Medicine, Istanbul University, Istanbul, Türkiye.
Importance: Increasing evidence supports the oncologic safety of de-escalating axillary surgery for patients with breast cancer after neoadjuvant chemotherapy (NAC).
Objective: To evaluate the oncologic outcomes of de-escalating axillary surgery among patients with clinically node (cN)-positive breast cancer and patients whose disease became cN negative after NAC (ycN negative).
Design, Setting, And Participants: In the NEOSENTITURK MF-1803 prospective cohort registry trial, patients from 37 centers with cT1-4N1-3M0 disease treated with sentinel lymph node biopsy (SLNB) or targeted axillary dissection (TAD) alone or with ypN-negative or ypN-positive disease after NAC were recruited between February 15, 2019, and January 1, 2023, and evaluated.
Outcomes of Importance to Patients Living With Cutaneous Chronic Graft-vs-Host Disease.
JAMA Dermatol
January 2025
Department of Dermatology, University of Pennsylvania, Philadelphia.
Importance: Cutaneous chronic graft-vs-host disease (GVHD) is independently associated with morbidity and mortality after allogeneic hematopoietic cell transplant. However, the health-related quality-of-life (HRQOL) domains that are most important to patients are poorly understood.
Objective: To perform a concept elicitation study to define HRQOL in cutaneous chronic GVHD from the patient perspective and to compare experiences of patients with epidermal vs sclerotic disease.
Geographic Distribution of US Ophthalmic Surgical Subspecialists.
JAMA Ophthalmol
January 2025
The Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, Maryland.
Importance: While urban counties maintain higher densities of ophthalmologists than rural counties, the geographic distribution of ophthalmic surgical subspecialists has not yet been elucidated. A potential workforce discrepancy may impact the burden of care faced by rural surgeons.
Objective: To assess the geographic distribution of the ophthalmic subspecialist surgeon workforce and evaluate factors associated with practicing in rural areas.
