This study aimed at finding out the most effective clinical samples and methods in chronic cutaneous leishmaniasis (CCL). Smear, aspiration fluid, and filter paper samples were taken from 104 skin lesions of suspected cases with CCL, and they were compared using microscopic examination, culture, and molecular methods. We characterized four different forms of CCL and identified the causative agents in CCL forms using high-resolution melting curve real-time polymerase chain reaction assay. We observed that smear was detected to be the most sensitive (63.5%) among clinical samples, and real-time polymerase chain reaction method was the most sensitive (96.8%) among the methods used in diagnosis of CCL. We identified 68.8% Leishmania tropica and 31.2% L. infantum in papular lesions, 69.2% L. infantum and 30.8% L. tropica in nodular lesions, 57.9% L. tropica and 42.1% L. major in ulcerating plaque lesions, and 55.5% L. tropica and 44.5% L. major in noduloulcerative lesions in CCL patients.

Assessing Physician and Patient Agreement on Whether Patient Outcomes Captured in Clinical Progress Notes Reflect Treatment Success: Cross-Sectional Study.
J Particip Med
January 2025
School of Medicine, University of South Carolina, Greenville, SC, United States.
Background: It remains unclear if there is agreement between physicians and patients on the definition of treatment success following orthopedic treatment. Clinical progress notes are generated during each health care encounter and include information on current disease symptoms, rehabilitation progress, and treatment outcomes.
Objective: This study aims to assess if physicians and patients agree on whether patient outcomes captured in clinical progress notes reflect a successful treatment outcome following orthopedic care.
Effectiveness of Oral Prophylactic Antibiotics for Diagnostic Bronchoscopy: A Nationwide Database Study.
Ann Am Thorac Soc
January 2025
The University of Tokyo, Department of Clinical Epidemiology and Health Economics, Bunkyo-ku, Tokyo, Japan.
Rationale: Although the guidelines generally omit routine antibiotic prophylaxis for diagnostic bronchoscopy, this recommendation is primarily based on studies with relatively small sample sizes conducted at single institutions. Moreover, the applicability of recent technical and procedural advancements to these guidelines remains uncertain.
Objectives: To evaluate whether oral prophylactic antibiotic administration for diagnostic bronchoscopy reduces post-bronchoscopy infections among non-infectious diseases in the current setting.
Enhanced Antibiotic Release and Mechanical Strength in UHMWPE Antibiotic Blends: The Role of Submicron Gentamicin Sulfate Particles.
J Bone Joint Surg Am
January 2025
Harris Orthopaedics Laboratory, Massachusetts General Hospital, Boston, Massachusetts.
Background: Periprosthetic joint infections (PJIs) are a major complication of total joint replacement surgeries. This study investigated the enhancement of mechanical properties and antibiotic release in ultra-high molecular weight polyethylene (UHMWPE) through the encapsulation of submicron gentamicin sulfate (GS) particles, addressing the critical need for improved implant materials in orthopaedic surgery, particularly in managing PJIs.
Methods: The present study involved embedding submicron GS particles into UHMWPE flakes at concentrations of 2% to 10% by weight.
A novel microsatellite instability test of sebaceous tumours to facilitate low cost universal screening for Lynch syndrome.
Clin Exp Dermatol
January 2025
Translational and Clinical Research Institute, Faculty of Medical Sciences, Newcastle University, Newcastle upon Tyne, UK.
Background: One in five sebaceous tumour (ST) patients may have Lynch syndrome (LS), a hereditary cancer predisposition. LS patients benefit from cancer surveillance and prevention programmes and immunotherapy. Whilst universal tumour mismatch repair (MMR) deficiency testing is recommended in colorectal and endometrial cancers to screen for LS, there is no consensus screening strategy for ST, leading to low testing rates and inequity of care.

PLoS Med
January 2025
Division of Psychiatry, University College London, London, United Kingdom.
Background: There is limited and conflicting evidence on the comparative cardiometabolic safety and effectiveness of aripiprazole in the management of severe mental illness. We investigated the hypothesis that aripiprazole has a favourable cardiometabolic profile, but similar effectiveness when compared to olanzapine, quetiapine, and risperidone.
Methods And Findings: We conducted an observational emulation of a head-to-head trial of aripiprazole versus olanzapine, quetiapine, and risperidone in UK primary care using data from the Clinical Practice Research Datalink.
