Cutaneous sporotrichosis is a fungal infection caused by traumatic inoculation of Sporothrix. We aimed to study
the clinical characteristics of human sporotrichosis, risk factors for infection, the yield of diagnostic methods and
therapeutic response to standard clinical therapy. A cohort study of was performed. A total of 29 patients with
clinical features suggestive of sporotrichosis were recruited within a one-year period from all public hospitals in
Kedah, Malaysia. Majority were females (86%) who were housewives (69%). The most common comorbidities
were diabetes mellitus (38%), hypertension (31%) and dyslipidaemia (21%), none was a significant risk factor for
severity of infection. Mean duration of disease was 2±2 months. More than 2/3 of the patients (79%) had pet cats,
14(48%) recalled minor cat-inflicted trauma. Lymphocutaneous sporotrichosis (62%) was more common than
fixed cutaneous type, affecting the upper limbs in 94%. Ulcerations and nodules were the main lesion morphology.
Histopathology showed granulomatous inflammation in 72%, culture grew Sprorothrix in 55% and polymerase
chain reaction (PCR) detected Sporothrix schenkii sensu stricto in 65%. Itraconazole was effective with 93% of
patients achieving complete resolution with 4 months of therapy. Sporotrichosis in Malaysia remains endemic.
Feline contact is the most important risk factor for infection. Diagnosis is best confirmed with tissue PCR while
culture and histopathology are also useful. Sporothrix schenkii sensu stricto was the only species identified and
itraconazole is an effective first line therapeutic agent.

This article outlines the systematic radiological approach preoperative evaluation of perihilar cholangiocarcinoma (pCCA) using CT and MRI to provide key information regarding the suitability for curative surgical resection. It discusses older classification systems (BismuthCorlette, Memorial Sloan Kettering Cancer Center T staging) and follows the Korean Society of Abdominal Radiology 2019 consensus recommendations for step-by-step assessment.The correlation between radiological, surgical, and pathological findings is illustrated through a pictorial review of pathologically proven cases. Benign and malignant mimics of pCCA are included to provide a comprehensive overview.

INTRODUCTION:
This review aims to provide evidence-based recommendations for an enhanced primary series (third dose) coronavirus disease 2019 (COVID-19) vaccination in people with rheumatic diseases (PRDs) in the local and regional context.
METHODS:
Literature reviews were performed regarding the necessity, efficacy, safety and strategies for enhanced primary series COVID-19 vaccination in PRDs. Recommendations were developed based on evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Evidence was synthesised by eight working group members, and the consensus was achieved by a Delphi method with nine members of an expert task force panel.
RESULTS:
Two graded recommendations and one ungraded position statement were developed. PRDs have impaired immunogenicity from the COVID-19 vaccine and are at an increased risk of postvaccine breakthrough severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and poor clinical outcomes, compared to the general population. We strongly recommend that PRDs on immunomodulatory drugs be offered a third dose of the messenger RNA (mRNA) vaccine as part of an enhanced primary series, after the standard two-dose regimen. We conditionally recommend that the third dose of mRNA vaccine against SARS-CoV-2 be given at least 4 weeks after the second dose or as soon as possible thereafter. There is insufficient data to inform whether the third mRNA vaccine should be homologous or heterologous in PRDs.
CONCLUSION
These recommendations that were developed through evidence synthesis and formal consensus process provide guidance for an enhanced primary series COVID-19 vaccination in PRDs.

Objective:
Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery.
Methodology:
Ten NAFLD participants were studied at baseline and 6 months post-bariatric surgery. Blood samples were collected for serum biomarkers and metabolomic profiling. Hepatic steatosis [proton density fat fraction (PDFF)] and fibroinflammation (cT1) were quantified with multiparametric magnetic resonance imaging (mpMRI), and hepatic stiffness with magnetic resonance elastography (MRE). Amino acids and acylcarnitines were measured with mass spectrometry. Statistical analyses included paired Student’s t-test, Wilcoxon-signed rank test, and Pearson’s correlation.
Results:
Eight participants provided complete data. At baseline, all had hepatic steatosis (BMI 39.3 ± 5.6 kg/m2, PDFF ≥ 5%). Post-surgery reductions in PDFF (from 12.4 ± 6.7% to 6.2 ± 2.8%, p = 0.013) and cT1 (from 823.3 ± 85.4ms to 757.5 ± 41.6ms, p = 0.039) were significant, along with the GSG index (from 0.272 ± 0.03 to 0.157 ± 0.05, p = 0.001).
Conclusion
The GSG index can potentially be developed as a marker for monitoring the response of patients with NAFLD to bariatric surgery.
