Introduction: The transformative feature of Artificial Intelligence (AI) is the massive capacity for interpreting and transforming unstructured data into a coherent and meaningful context. In general, the potential that AI will alter traditional approaches to student research and its evaluation appears to be significant. With regard to research in global health, it is important for students and research experts to assess strengths and limitations of GenAI within this space.

Background: The vaccine supply chain (VSC) integrates all activities from production to dispensing, characterized by complexity and low responsiveness. This study aims to define key performance indicators (KPIs) to evaluate the logistic and operational performance during the COVID-19 National Vaccination Plan in Colombia.

Methods: This study employed the design science research (DSR) methodology to develop a dashboard for monitoring COVID-19 vaccination progress.

Article Synopsis
  • High driving pressure (DP) during mechanical ventilation can negatively impact outcomes in pediatric patients with acute respiratory distress syndrome (PARDS), particularly regarding 28-day mortality rates.
  • A study of 184 intubated children showed that those with a DP greater than 15 cm H2O at 72 hours had a higher risk for mortality and longer ventilation duration.
  • Key findings included that lower tidal volumes were linked to decreased mortality risk, while higher plateau pressures in non-survivors highlighted the importance of managing ventilation parameters effectively.*

Introduction: Over 10 million Americans misuse opioids and more than 5 million have been diagnosed with an opioid use disorder (OUD). In 2021, over 100,000 Americans died of a drug overdose and more than 75% of these deaths involved an opioid. Exercise has been shown to increase abstinence and decrease anxiety and depression in people with a substance use disorder.

The current systematic review synthesized available original research on objective and self-reported sleep health dimensions among adults aged 18 to 50 years in outpatient treatment for opioid use disorder (OUD). A comprehensive search was conducted using multiple electronic databases followed by screening 2,738 records published in English from the inception of each database to September 14, 2021. Quality was assessed with the Mixed Methods Appraisal Tool (version 2001).

The purpose of this study was to explore perceptions of the first dose of a cognitive behavioral sleep self-management intervention (CB-sleep) among young adults aged 18 to 25 years with type 1 diabetes (T1D). We used a qualitative descriptive approach to conduct in-depth semi-structured focused interviews with a purposive sample of 16 young adults with T1D, transitioning from adolescence to early adulthood. Interviews were audio-recorded, transcribed verbatim, and analyzed using qualitative content analysis.

Glucose variations have a bidirectional relationship with the sleep/wake and circadian systems in type 1 diabetes (T1D); however, the mechanisms remain unclear. The aim of this study was to describe the coupling between glucose and unstructured physical activity over 168 h in young adults with T1D. We hypothesized that there would be differences in sleep and wake characteristics and circadian variations.

The COVID-19 vaccination process in Colombia has been a major challenge not only in terms of public health but also in terms of supply chain management and logistics processes. To support the monitoring of these processes and associated decision-making, a dashboard was designed in Google Data Studio focused on analyzing the progress of COVID-19 vaccination and its logistics efficiency. This article describes the design and implementation of the dashboard using a design science approach and discusses the main lessons learned.

To gain insight into current use of social-media platforms in human services delivery, we systematically surveyed 172 social-service workers from six agencies in a Midwest US city to gather data about social-media usage among social-service providers, potential challenges and benefits of using social media, and whether a social-media-based informatics platform could be valuable. Quantitative analyses showed that approximately half of participants have used social media to collect client-related information; nearly one-quarter indicated "often" or "nearly daily" use. Adjusting for the effects of worker characteristics, social-media use was associated with the type of agency involved and with increased tenure in social services.

This study investigated disparities in residential exposure to carcinogenic air pollutants among Asian Americans, including Asian ancestry subgroups, in four US metro areas with high proportions of Asians, i.e., Honolulu, Los Angeles, San Francisco Bay Area, and Seattle.

This article draws on two decades of media representations of HIV, ethnographic research among people living with HIV, and an analysis of global health programms in Bolivia. In doing so, we chart the evolution of media representations in relation to the global health context and the implications of these representations for people living with HIV. Our overarching argument is that media discourses on HIV in Bolivia have consistently been produced in a context of an unequal balance of power between global health bodies and local actors.

We describe the case of a 13-year-old girl with paradoxical vocal fold motion (PVFM) who failed to improve with repeated medical treatment, speech therapy and psychotherapy, but was successfully treated with botulinum toxin A (BTX-A) injection to the vocal folds. For delivering the BTX-A we used a channeled fiber-optic laryngoscope under local anesthesia, in an office setting. The patient remained asymptomatic of PVFM for 5 months, was successfully treated again with the same method, and had no important side effects.

Article Synopsis
  • Male golden-collared manakins perform intricate courtship displays on leks to attract females, but the role of testosterone (T) in these displays, particularly in tropical species, is less understood than in temperate species.
  • Previous research indicates that T can activate display behavior in manakin males, but high levels of T during the courtship season were not observed in many adult males, unlike in temperate species.
  • T implants showed that while juvenile males and females could display under T treatment, adult males did not increase their display frequency, highlighting that the influence of T on manakin displays varies by season, sex, and age, and that high T is not essential for these displays.

In most bird species, male courtship behavior is controlled by testosterone (T) and its metabolites. In species breeding in temperate and arctic regions T circulates at high levels during a relatively short courtship period because high levels of T can be costly in terms of immunocompetence and parental care. Few studies have investigated androgen modulation of courtship behavior in tropical birds.
