Background: Antimicrobial stewardship programs (ASP) often function naturally as facilitators within clinical hospital settings, by working with individuals and teams to reduce unnecessary antibiotics. Within implementation science, facilitation has been studied and evaluated as an implementation strategy that can accelerate and improve fidelity to implementation efforts. This study describes a novel, virtual facilitation strategy developed and served as an intervention within the optimizing perioperative antibiotics for children trial (OPERATIC trial).

Article Synopsis
  • Previous research shows that exercise impacts immune responses, but there's little focus on its effects on cytokine levels in bipolar disorder (BD) and schizophrenia (SCH).
  • This study investigates both the immediate and long-term effects of a 10-week resistance exercise program on cytokine levels, symptoms, and muscular strength in individuals with BD and SCH.
  • Results indicate that acute resistance exercise significantly increased IL-2 and IL-4 levels while decreasing IL-6, and chronic exercise led to sustained increases in IL-2 and IL-4, reduced disease symptoms, and improved muscular strength.

Background: Bipolar disorder (BD) and schizophrenia (SZ) are the two main mental disorders with unknown etiology that significantly impact individuals' quality of life. The potential pro-inflammatory role in their pathogenesis is postulated and Human Endogenous Retrovirus W (HERV-W) is an emerging candidate to modulate this pathogenic finding. HERVs, ancient retroviruses in the human genome, may play roles in inflammation and disease pathogenesis.

There have been over 769 million cases of COVID-19, and up to 50% of infected individuals are asymptomatic. The purpose of this study aimed to assess the use of a clinical-grade physiological wearable monitoring system, ANNE One, to develop an artificial intelligence algorithm for (1) cough detection and (2) early detection of COVID-19, through the retrospective analysis of prospectively collected physiological data from longitudinal wear of ANNE sensors in a multicenter single arm study of subjects at high risk for COVID-19 due to occupational or home exposures. The study employed a two-fold approach: cough detection algorithm development and COVID-19 detection algorithm development.

Internet platforms have become a common source of information for individuals with skin diseases such as vitiligo, and the vitiligo community frequently turns to online sources for diet modifications that may be beneficial for their disease. In this study, our objective was to summarize information from the most frequently visited websites providing diet suggestions that reportedly affected vitiligo symptoms. Notable diet categories for food components included vitamins, fruits, omega-3 fatty acids, grains, minerals, vegetables, and nuts.

Article Synopsis
  • The study aims to compare postoperative drainage rates and culture profiles in children with complicated appendicitis treated with two common antibiotic regimens: piperacillin-tazobactam (PT) and ceftriaxone with metronidazole (CM).
  • A retrospective analysis of 1,002 children from 15 hospitals was conducted between 2015 and 2020, leading to a matched sample of 778 patients for comparison of drainage rates and infection-related cultures.
  • Results showed that PT had similar overall drainage rates to CM but higher rates of drainage related to specific organisms, indicating that the use of antipseudomonal antibiotics did not lead to better outcomes in this context.

Background/purpose: Cephalosporins are considered safe and first-line prophylaxis in children with non-severe penicillin allergies. However, use of second-line agents is common and is primarily driven by poor allergic response documentation and misunderstanding of cross-reactivity risk. The goal of this project was to improve compliance with cephalosporin prophylaxis through improved documentation and targeted educational efforts.

Keloids are benign, fibroproliferative dermal tumors that typically form owing to abnormal wound healing. The current standard of care is generally ineffective and does not prevent recurrence. To characterize keloid scars and better understand the mechanism of their formation, we performed transcriptomic profiling of keloid biopsies from a total of 25 subjects of diverse racial and ethnic origins, 15 of whom provided a paired nonlesional sample, a longitudinal sample, or both.

Initiating end-of-life conversations can be daunting for clinicians and overwhelming for patients and families. This leads to delays in communicating prognosis and preparing for the inevitable in old age, often generating potentially harmful overtreatment and poor-quality deaths. We aimed to develop an electronic resource, called Communicating Health Alternatives Tool (CHAT) that was compatible with hospital medical records software to facilitate preparation for shared decision-making across health settings with older adults deemed to be in the last year of life.
