Background: The rapid growth of research in artificial intelligence (AI) and machine learning (ML) continues. However, it is unclear whether this growth reflects an increase in desirable study attributes or merely perpetuates the same issues previously raised in the literature.

Objective: This study aims to evaluate temporal trends in AI/ML studies over time and identify variations that are not apparent from aggregated totals at a single point in time.

Article Synopsis
  • The study explores Disorders of Gut Brain Interaction (DGBI), which are gastrointestinal issues linked with psychological conditions, highlighting that current diagnostic criteria (Rome IV) ignore psychological symptoms.
  • Using data from the Rome Foundation Global Epidemiology Study, researchers applied latent profile models to find how individuals with GI symptoms cluster when considering both GI and psychological symptoms versus GI symptoms alone.
  • Results showed a high degree of similarity in clustering, suggesting that incorporating psychological traits into DGBI classification could lead to more accurate and nuanced categorization of individuals with these disorders.

Article Synopsis
  • Intelligent lower-limb prostheses (LLPs) utilize advanced technologies like microcontrollers and user-controlled interfaces, leading to more complex wearer interactions compared to traditional prosthetics.
  • The existing frameworks for evaluating wearer-LLP interactions are insufficient due to the new dynamics and elements introduced by these intelligent devices, such as transparency and usability requirements.
  • A proposed new framework organizes human factors into three categories (wearer, device, task) and introduces Nielsen's five usability requirements—learnability, efficiency, memorability, use error, and satisfaction—to improve the interaction between wearers and intelligent LLPs.

The "countervailing powers" framework conceptualizes health care as an arena for power contests among key stakeholders, drawing attention to the moves, countermoves, and alliances that have challenged physicians' dominance since the 1970s. Here, we focus on one of the lesser known micro-level consequences of such forces for physicians: emotional distress. We draw on 145 interviews with frontline physicians across four U.

Instrumental variable analysis uses naturally occurring variation to estimate the causal effects of treatments, interventions, and risk factors on outcomes in the population from observational data. Under specific assumptions, instrumental variable methods can provide unbiased estimates of causal effects. This article explains these assumptions and the information and tests typically reported in instrumental variable studies, which can assess the credibility of the findings of instrumental variable studies.

Individuals with low socioeconomic position (SEP) experience greater rates of alcohol-attributable mortality, contributing to health inequities in mortality and life expectancy. We examined the association between SEP and alcohol-attributable mortality by sex/gender and age in Canada. Census records from the 2006 Canadian Census Health and Environment Cohort (ages 12+; n=5,038,790) were linked to mortality data from 2006-2019.

Background: Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common disorders of gut-brain interaction (DGBI). The Rome IV criteria are the gold standard for research when diagnosing DGBI. However, bothersomeness, or the degree to which symptoms are distressing or disruptive to a person's daily life, is a potential treatment-seeking motivator that is not assessed by the Rome criteria.

Racism in Pediatric Serious Illness and Palliative Care: A Scoping Review of Qualitative Research.

J Pain Symptom Manage

January 2025

Division of Palliative Medicine (D.K., K.A.J.), Department of Family and Preventative Medicine, Emory University, Atlanta, GA; Children's Healthcare of Atlanta (K.A.J.), Atlanta, GA.

Context: Racial disparities in health outcomes have historically impacted Black and Native American children with serious illness, yet little is known about how racism shapes the healthcare experiences of these families. To improve care experiences for this population, we must understand the myriad of ways that racism may impact their experiences with serious illness.

Objectives: 1) To assess the extent to which the experiences of Black and Native American families have been captured in existing serious illness and palliative care literature and 2) explore how experiences of racism uniquely impact this population.

Article Synopsis
  • The study looked at how tough childhood experiences, feeling discriminated against, and mental health issues like anxiety and depression are connected for LGBTQ+ adults in the U.S.
  • Researchers surveyed over 4,000 people and found that negative childhood events increased feelings of discrimination, which then led to more anxiety and depression.
  • They believe that these challenges build up over time and suggest that helping kids have better experiences can prevent mental health problems later on.*

Spinoza, Liberation From Causation, and Community Health Promotion.

Am J Health Promot

January 2025

Peers for Progress and Department of Health Behavior, Gillings School of Global Public Health, University of North Carolina Chapel Hill, Chapel Hill, NC, USA.

What sense does it make to say that a new program implemented in a community with roots as old as evolution caused an observed health benefit? Evaluation of community approaches has often sought to isolate the causal roles of interventions. Central to this is the assumption that there are causes to be proven and isolated. Benedict Spinoza (1632-1677) dismissed the concept of cause, arguing that all things, "substances," are not caused but simply are.

Assessing generalizability of an AI-based visual test for cervical cancer screening.

PLOS Digit Health

October 2024

Clinical Epidemiology Unit, Clinical Genetics Branch, Division of Cancer Epidemiology and Genetics, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, United States of America.

A number of challenges hinder artificial intelligence (AI) models from effective clinical translation. Foremost among these challenges is the lack of generalizability, which is defined as the ability of a model to perform well on datasets that have different characteristics from the training data. We recently investigated the development of an AI pipeline on digital images of the cervix, utilizing a multi-heterogeneous dataset of 9,462 women (17,013 images) and a multi-stage model selection and optimization approach, to generate a diagnostic classifier able to classify images of the cervix into "normal", "indeterminate" and "precancer/cancer" (denoted as "precancer+") categories.

Rodent drug self-administration leads to compromised ability of astrocytes to maintain glutamate homeostasis within the brain's reward circuitry, as well as reductions in surface area, volume, and synaptic colocalization of astrocyte membranes. However, the mechanisms driving astrocyte responses to cocaine are unknown. Here, we report that long-access cocaine self-administration followed by prolonged home cage abstinence results in decreased branching complexity of nucleus accumbens astrocytes, characterized by the loss of peripheral processes.

  • - A study created a detailed map of the airway cells in patients with pulmonary long COVID, focusing on those who have persistent respiratory symptoms after a COVID-19 infection.
  • - Participants with long COVID were compared to those whose symptoms had resolved or who had never been infected, with analysis revealing unique neutrophil clusters in the long COVID group.
  • - The findings suggest that increased inflammation and changes in airway cell function, particularly involving neutrophils, may be responsible for the lingering respiratory issues seen in long COVID patients.
