This comprehensive review critically examines the UK medical curriculum, with a particular focus on progress testing as an innovative assessment strategy. The curriculum, evolving from foundational sciences to practical applications, is encapsulated in the integrated curriculum model (ICM). This model adeptly combines theoretical knowledge with clinical practice, fostering cognitive, affective, and psychomotor skills among medical students.

Article Synopsis
  • Magnetic Resonance Imaging (MRI) is essential for diagnosing Alzheimer's Disease (AD) but is often slow due to the need for expertise in optimizing imaging protocols, which affects its clinical value.
  • The study shows how a deep learning-based approach can enhance MRI efficiency by improving image quality and increasing imaging throughput by 1.94 times using an accelerated protocol known as the Gold Standard (GS) protocol.
  • The GS protocol is a significant part of comprehensive AD imaging, and the study also explores its potential for automating volumetric measurements of relevant brain structures related to AD diagnosis.

Due to the increase in pollution, the number of deaths caused by lung disease is rising rapidly. It is essential to predict the disease in earlier stages by means of high-level knowledge and acquaintance. Deep learning-based lung cancer prediction plays a vital role in assisting the medical practioners for diagnosing lung cancer in earlier stage.

Background: Frailty is a state of age-related physiological vulnerability resulting from impaired homeostatic reserve and a reduced capacity of the individual to withstand stress and an independent predictor of deleterious health outcomes among the aged. Early identification of people who are at risk for frailty is vital in preventing and minimizing its socio-economic consequences in low-resource countries like India. However, risk factors for frailty among Indian institutionalized older adults have been seldom explored.

Aims/hypothesis: Weight loss is often recommended in the treatment of type 2 diabetes. While evidence has shown that large weight loss may lead to diabetes remission and improvement in cardiovascular risk factors, long-term impacts are unclear. We performed a systematic review of studies of weight loss and other weight changes and incidence of CVD among people with type 2 diabetes.

In this pandemic era there exist a relationship between a sedentary lifestyle during lockdown with periods of anxiety and stress among the population. Moreover, the population with chronic disease will be vulnerable to the ill effects of a physically inactive lifestyle. Besides, social media platforms and technological advances also appear to be another potential tool for promoting health and wellbeing, however, the capability of these interventions during the pandemic era is largely unknown.

Purpose: To compare visual outcomes, complications, and vision-related quality of life (QoL) after microthin Descemet stripping automated endothelial keratoplasty (MT-DSAEK) versus Descemet membrane endothelial keratoplasty (DMEK) for the management of corneal endothelial dysfunction in Fuchs dystrophy.

Methods: This is a prospective, double-blinded randomized controlled clinical trial. Patients with visually significant endothelial decompensation from Fuchs dystrophy were prospectively randomized to receive MT-DSAEK or DMEK surgery.

Purpose: To provide expert guidance to clinicians and policymakers in resource-constrained settings on the management of patients with late-stage colorectal cancer.

Methods: ASCO convened a multidisciplinary, multinational Expert Panel that reviewed existing guidelines, conducted a modified ADAPTE process, and used a formal consensus process with additional experts for two rounds of formal ratings.

Results: Existing sets of guidelines from four guideline developers were identified and reviewed; adapted recommendations from five guidelines form the evidence base and provided evidence to inform the formal consensus process, which resulted in agreement of ≥ 75% on all recommendations.

Purpose: To provide resource-stratified, evidence-based recommendations on the early detection of colorectal cancer in four tiers to clinicians, patients, and caregivers.

Methods: American Society of Clinical Oncology convened a multidisciplinary, multinational panel of medical oncology, surgical oncology, surgery, gastroenterology, health technology assessment, cancer epidemiology, pathology, radiology, radiation oncology, and patient advocacy experts. The Expert Panel reviewed existing guidelines and conducted a modified ADAPTE process and a formal consensus-based process with additional experts (Consensus Ratings Group) for two round(s) of formal ratings.

Purpose: To provide resource-stratified, evidence-based recommendations on the treatment and follow-up of patients with early-stage colorectal cancer.

Methods: ASCO convened a multidisciplinary, multinational Expert Panel that reviewed existing guidelines and conducted a modified ADAPTE process and a formal consensus process with additional experts for one round of formal ratings.

Results: Existing sets of guidelines from 12 guideline developers were identified and reviewed; adapted recommendations from six guidelines form the evidence base and provide evidence to inform the formal consensus process, which resulted in agreement of 75% or more on all recommendations.

Introduction: Healthy behaviour through education of individuals with arthritis is the mainstay of long term management. Time and access constraints restrict medical professionals from active involvement in arthritis education in the community. Reaching the community through the Accredited Social Health Activists (ASHAs) is the plan of action operational in India.

Background: The risk of metastatic disease among carcinoid tumors of the appendix increases with tumor size. However, it is unclear if any features other than size are also associated with an increased risk of metastatic disease.

Objective: The aim of this study was to review the characteristics of appendiceal carcinoid tumors and determine if other histologic features besides size should guide surgical decision making.

Background/aims: Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided GBS (EUS-GBS) have been proposed as safe and effective modalities for gallbladder drainage.

Current orthotopic xenograft models of human colorectal cancer (CRC) require surgery and do not robustly form metastases in the liver, the most common site clinically. CCR9 traffics lymphocytes to intestine and colorectum. We engineered use of the chemokine receptor CCR9 in CRC cell lines and patient-derived cells to create primary gastrointestinal (GI) tumors in immunodeficient mice by tail-vein injection rather than surgery.

Epidermal cysts are common skin lesions but they occur very rarely in the oral cavity, especially in the salivary glands. Very few cases have been reported in the literature and, here, we present one such rare case of epidermal cyst in the right parotid gland in a 62-year-old female patient.

Background: Following colon resection, the construction of a well-perfused, tension-free isoperistaltic anastomosis can be made difficult by multiple factors including prior abdominal surgery or compromised vascular supply. Here, we describe the technique of antiperistaltic cecorectal anastomosis as a method for preserving viable colon without compromising functional outcome.

Technique: Following extensive colorectal resection, different techniques for isoperistaltic reconstruction using the cecum and ascending colon have been described, including the Deloyers procedure and limited isoperistaltic cecorectal anastomosis.

Cutaneous leishmaniasis (CL), a neglected tropical disease, is reported to be prevalent in tribal villages located in the Agasthyamala Biosphere Reserve forests of Western Ghats, Kerala state, India. We carried out an investigation to characterize the species of Leishmania parasites involved in these infections prevalent among one of the oldest human tribal populations in India. Skin aspirates collected from 13 clinically diagnosed cases were subjected to histopathological investigations, serological rapid tests using 'rk39' and molecular diagnostics.
