Background: The burden of foodborne diseases and antimicrobial resistance carried by key foodborne pathogens in India is unknown due to a lack of an integrated surveillance system at the human-animal interface.

Methods: We present data from the WHO-AGISAR (Advisory Group on Integrated Surveillance of Antimicrobial Resistance), India project. Concurrent human and animal sampling was done across a large area across north India.

Enteroaggregative Escherichia coli (EAEC) is an evolving enteric pathogen that causes acute and chronic diarrhea in developed and industrialized nations in children. EAEC epidemiology and the importance of atypical EAEC (aEAEC) isolation in childhood diarrhea are not well documented in the Indian setting. A comparative analysis was undertaken to evaluate virulence, phylogeny, and antibiotic sensitivity among typical tEAEC versus aEAEC.

This article explores the assessment of professionalism within a cohort of medical students during a sequential 13-week medical school histology and anatomy course. Across seven data points, students were asked to identify a professionalism role model from amongst their peers and to score Likert-structured rationales for their decision. Based on density scores, an initial social network analysis identified six peer-nomination "stars.

Objectives: Caregiving can negatively impact well-being. Cancer caregivers face unique challenges given the intense nature of cancer and treatment, which increases their risk for burden, poor quality of life (QOL), and burnout. Studies to reduce caregiver burden demonstrate QOL improvement and distress reduction in the short term.

Background/aims: Pernio (chilblains) is an inflammatory condition classically characterized by localized erythema and swelling of acral sites upon exposure to cool and damp conditions. We sought to determine whether cold-induced vasospasm has a role in the development of pernio.

Methods: We retrospectively reviewed 5 patients with pernio who were seen at our institution between January 1, 2000 and December 31, 2011, and had undergone a noninvasive arterial vascular study of the upper extremities that corresponded to a site of clinical involvement of pernio and who had also undergone vasospastic testing and ice water immersion as part of the noninvasive arterial vascular study protocol.

Purpose: To conduct a systematic review and meta-analysis of complication rates and outcomes in patients undergoing endovascular procedures who receive uninterrupted versus interrupted warfarin therapy.

Materials And Methods: Literature published between 1990 and 2014 was searched for reports of comparative studies of vascular procedures. Information on periprocedural complications and patient deaths less than 30 days after the procedure was extracted.

Background: Pyoderma gangrenosum (PG) can be associated with systemic diseases, including inflammatory bowel disease, inflammatory arthritis, and hematologic malignancy. Previous literature exploring the rare association between PG and solid organ malignancy is predominantly limited to single case reports.

Methods: We retrospectively reviewed the cases of five patients with PG and solid organ malignancies at our institution between 1996 and 2013.

Objective: There are significant burdens associated with providing care for loved ones with cancer. However, caregiver quality of life (QOL) is often overlooked. With the increasing number of older adults with cancer, it is important to determine whether a patient's age and QOL have any association with the caregiver's QOL.
