Background: Magnetic resonance imaging (MRI) of the thigh is used in diagnosis of idiopathic inflammatory myositis (IIM) diagnosis due to its high sensitivity in detecting muscle oedema and to localize the site for muscle biopsy. At the same time, dual energy absorptiometry (DXA) is an accepted method in clinical practice to measure muscle mass and change in body composition. In this longitudinal study of patients with active IIM we sought to correlate muscle findings on serial thigh MRI and body composition assessed using DXA with six-month clinical outcomes, we also studied correlation of thigh MRI scores with body composition parameters.

Traditional phase I dose finding cancer clinical trial designs aim to determine the maximum tolerated dose (MTD) of the investigational cytotoxic agent based on a single toxicity outcome, assuming a monotone dose-response relationship. However, this assumption might not always hold for newly emerging therapies such as immuno-oncology therapies and molecularly targeted therapies, making conventional dose finding trial designs based on toxicity no longer appropriate. To tackle this issue, numerous early-phase dose finding clinical trial designs have been developed to identify the optimal biological dose (OBD), which takes both toxicity and efficacy outcomes into account.

Background: Cuff extrusion of tunneled dialysis catheter (TDC) leads to catheter dysfunction, leading to loss of vascular access and the need for new catheter. Definitive management is to remove TDC and reinsert new catheter by new venous puncture and tunnel, which may not be possible in all cases. The study evaluated the surgical experience and early outcomes of a novel "Catheter Exchange with Elongation of Tunnel (CEET)" procedure for cuff extrusion.

Article Synopsis
  • A 48-year-old man with a history of mitral valve replacement and recent ischemic stroke experienced sudden angina and had not taken his anticoagulant medication for 50 days.
  • Upon examination, he exhibited severe hemodynamic instability, which was resolved using intravenous diltiazem, leading to stabilized blood pressure and heart rate.
  • Due to the unavailability of surgical options, he received thrombolytic treatment with Alteplase for prosthetic mitral valve thrombosis, resulting in improved valve function and symptom relief within 6 hours; he is now on strict anticoagulant therapy.

Article Synopsis
  • The study aimed to assess if adding docetaxel (D) to standard chemotherapy regimens improved overall survival (OS) in patients with advanced HER2-negative gastroesophageal junction and gastric adenocarcinomas.
  • Out of 324 patients enrolled, the analysis showed that FOLFOX/CAPOX provided a median OS of 10.1 months, while the DOF/DOX regimen resulted in 8.9 months, with no significant survival advantage from the addition of docetaxel (P = .70).
  • The study also noted higher rates of severe neutropenia and neuropathy in the DOF/DOX group and identified a surprisingly high incidence of BRCA1 and BRCA2 alterations

Two critical components of patient support systems for people with TB are regular counseling and locally managed nutritional support. As part of an ongoing differentiated TB care initiative called Tamil Nadu Kasanoi Erappila Thittam (meaning TB death-free initiative in Tamil, TN-KET) to reduce TB deaths, adults with TB with very severe undernutrition, respiratory insufficiency, or poor performance status are identified at diagnosis (triage-positive) and prioritized for referral, comprehensive clinical assessment, and inpatient care. Between January and June 2023, in 6 districts, a pilot exercise was conducted in which trained TB survivors, known as TB champions, provided baseline counseling and additional counseling (if required) to triage-positive people with TB at diagnosis.

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).

Mechanical problems like break or crack in Luer connectors or hubs, clamps, and tubings are common non-infectious complications of tunneled dialysis catheters (TDC), which may lead to other TDC complications and the need to insert a new catheter. These can be tackled using TDC repair kits or spare parts, which are often not available, resulting in the insertion of a new TDC that increases morbidity, TDC-related procedures, and healthcare costs. We discuss two cases of broken Luer connections of TDC, which were managed by exchanging the broken Luer connector of TDC with the similar Luer connector of a temporary dialysis catheter.

The COVID-19 pandemic has disrupted systems of care for infectious diseases-including tuberculosis-and has exposed pervasive inequities that have long marred efforts to combat these diseases. The resulting health disparities often intersect at the individual and community levels in ways that heighten vulnerability to tuberculosis. Effective responses to tuberculosis (and other infectious diseases) must respond to these realities.

Bayesian Optimal Interval (BOIN) designs are a class of model-assisted dose-finding designs that can be used in oncology trials to determine the maximum tolerated dose (MTD) of a study drug based on safety or the optimal biological dose (OBD) based on safety and efficacy. BOIN designs provide a complete suite for dose finding in early phase trials, as well as a consistent way to explore different scenarios such as toxicity, efficacy, continuous outcomes, delayed toxicity or efficacy and drug combinations in a unified manner with easy access to software to implement most of these designs. Although built upon Bayesian probability models, BOIN designs are operationally simple in general and have good statistical operating characteristics compared to other dose-finding designs.
