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.

Article Synopsis
  • Anomalous aortic origin of a coronary artery is a rare condition where a coronary artery starts from an unusual spot in the aorta, which can lead to serious heart issues, especially in young athletes.
  • A study of 16 adult patients who had surgical repair showed that the majority underwent a technique called unroofing, with no deaths or major complications reported during the follow-up period.
  • The results indicate that surgical treatments like unroofing and neo-ostium creation lead to excellent outcomes, with all patients surviving and no significant health problems during an average follow-up of nearly 74 months.

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.*

Endotipsitis is an underdiagnosed entity mainly because it requires a high initial level of suspicion. It should be considered in the differential diagnosis of persistent bacteremia in the cirrhotic patient with TIPS. Most cases are treated conservatively with a long-term antibiotherapy, due to the impossibility of surgical removal of the TIPS, except in a liver transplant or autopsy.

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.

Unlabelled: We present a rare case of a coronary pseudoaneurysm after a Bentall-Bono procedure. During a routine follow-up computed tomography scan, a pseudoaneurysm located between the aorta and the proximal portion of the right coronary artery was diagnosed. Contrast extravasation was observed with partial thrombosis of the pseudoaneurysm.

Introduction And Objectives: Surgical aortic valve replacement (SAVR) can modify the natural history of severe aortic stenosis (SAS). However, compared with the general population, these patients have a loss of life expectancy. The life expectancy of patients who undergo SAVR due to low-gradient SAS with preserved left ventricular ejection fraction (LVEF) is unknown.

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 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.
