Background: Sporadic inclusion body myositis (s-IBM) is the most commonly occurring acquired inflammatory myopathy in elderly people (>45 years); however, pathogenic mechanisms are poorly understood and diagnostic tools are limited. In view of this, new therapeutic and diagnostic molecular markers for s-IBM need to be identified.

Experimental Design: In this study, the proteomes from three s-IBM cases were compared with those from three cases of neurogenic muscular atrophy (control). Proteins were separated by 2-dimensional polyacrylamide gel electrophoresis and profiled by mass spectrometric sequencing and subsequently validated by western blot.

Results: Differential expression was noted in 29 proteins (16 upregulated and 13 downregulated) in s-IBM compared with the control group. Functions of these proteins include oxidative stress response, regulation of apoptosis, signal transduction, and cytoskeleton. Expression of both amyloid precursor protein (APP) and αB-crystallin was increased in s-IBM cases.

Conclusions: Our study reveals a unique pattern of protein expression in s-IBM, which should be further investigated in a wider cohort of IBM patients to fully realize the potential diagnostic or therapeutic benefits.

Deficient Mismatch Repair and BRAF Mutations in Metastatic Colorectal Cancer in the South Island of New Zealand.

Wellington Blood and Cancer Centre, Health New Zealand/Te Whatu Ora - Capital, Coast and Hutt Valley, Wellington, New Zealand.

Aim: Manatū Hauora, the Ministry of Health of New Zealand (NZ), published minimum standards for molecular testing of colorectal cancers (CRCs) in June 2018. These included mismatch repair (MMR) testing at diagnosis and BRAFV600E mutation analysis on newly diagnosed stage IV CRCs. This study aimed to determine the proportion of patients with CRC in the South Island of NZ with metastatic deficient mismatch repair (dMMR) CRC, the proportion of metastatic CRCs and dMMR CRCs that have a BRAFV600E mutation, and audit testing for BRAF mutations and appropriate referral to genetics services.

For the past 50 years, significant progress has been made in understanding Seasonal Hyperacute Panuveitis (SHAPU), a mysterious blinding disease first reported in Nepal in 1975. Predominantly affecting Nepalese children, SHAPU occurs cyclically every odd year from September to December. While initially misclassified as endophthalmitis, SHAPU is set apart by its lack of trauma or surgery, failure to grow organisms in most intraocular fluid cultures, and its hallmark presentation of a "white pupil in red eye" with an association with moth exposure.

This volume makes a notable contribution with a deep and extensive analysis to achieve the movement from Yoga Philosophy to Yoga Psychology for the promotion of integration with Modern Psychology, a task hitherto unrealized despite the burgeoning attention to Yoga. This commentary is constrained by my own limited knowledge of traditional Indian philosophy in making a thorough examination of Paranjpe's contribution beyond attention to selected concepts and sporadic illustrations from the original volume. Yoga practice is, Paranjpe informs us, just the tip of an immense consolidation of knowledge, deep intellectual thought and theoretical consideration about the embodied sense of self, health and well-being.

Systemic therapy for metastatic Renal Cell Carcinoma (mRCC) has dramatical-ly improved in the last years because of the use of immunotherapy with checkpoint inhibi-tor combinations with or without targeted therapies against the Vascular Endothelial Growth Factor Receptors (VEGFR). As a result, patients with mRCC have prolonged sur-vival time, but they ultimately develop resistance and the disease progresses, which high-lights the critical need for novel treatment options. The Hypoxia-inducible Factor (HIF) pathway is central to the pathophysiology of ccRCC and von Hippel-Lindau (VHL) disease.

Cholera is linked to penury, making low- and middle-income countries (LMICs) particularly vulnerable to outbreaks. In this systematic review, we analyzed the drivers contributing to these outbreaks, focusing on the epidemiology of cholera in LMICs. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered in PROSPERO (ID: CRD42024591613).
