Purpose: There is currently scant research exploring Indigenous Guatemalan women's experiences of gender-based violence and mental health outcomes, but existing research suggests further exploration in this area is necessary. The current study aimed to address this gap by analyzing the experiences with violence and subsequent well-being of Indigenous Maya women in rural Guatemala.

Methods: Data were collected in an ethnographic project on mental health in Panajachel, Guatemala, consisting of a cross-sectional survey on violence exposure and mental health history, followed by semi-structured interviews to elaborate on the experiences.

A bidentate monoanionic ligand system was developed to enable iridium catalyzed C(sp)-H activation borylation of -methyl amides. Borylated amides were obtained in moderate to good isolated yields, and exclusive mono-borylation allowed the amide to be the limiting reagent. Selectivity for C(sp)-H activation was demonstrated in the presence of sterically available C(sp)-H bonds.

Cercarial dermatitis (‘swimmer's itch’; SI), characterized by small itchy bumps caused by schistosome parasites of birds and mammals, is a common problem in Michigan. Research on avian schistosomes began nearly 100 years ago in Michigan inland lakes, yet scientists are still uncovering basic biological information including the identification of local snail and parasite species that cause SI. Previous research primarily focused on lakes in the northern half of Michigan's lower peninsula, although SI occurs throughout the state.

Glenohumeral osteoarthritis: what the surgeon needs from the radiologist.

Skeletal Radiol

November 2023

Musculoskeletal Radiology, UT Southwestern, Dallas, TX, 75390-9178, USA.

Glenohumeral osteoarthritis (GHOA) is a widely prevalent disease with increasing frequency due to population aging. Both clinical manifestations and radiography play key roles in the initial diagnosis, staging, and management decisions. Radiographic disease progression evaluation is performed using validated staging systems, such as Kellgren and Lawrence, Samilson, and Hamada.

Background: Foot and ankle amputation is a feared complication of diabetic neuropathy and diabetes mellitus (DM) accounts for 80% of all in-hospital amputations. Magnetic resonance neurography is an effective tool in characterizing neuromuscular sequelae of the disease. However, conventional ankle MRI is more commonly performed and has not been studied to assess neuromuscular changes of DM.

The Hippocratic Oath.

Linacre Q

August 2022

Pediatric Critical Care, Cook Children's Medical Center, Fort Worth, TX, USA.

The Hippocratic Oath is the oldest and wisest description of our profession. It contains profound wisdom on the nature of health, healing, and the relationships both within and without that are necessary to the good practice of medicine. The practices described in its lines are antidotes for much of what ails modern medicine.

During the COVID-19 pandemic, predicting case spikes at the local level is important for a precise, targeted public health response and is generally done with compartmental models. The performance of compartmental models is highly dependent on the accuracy of their assumptions about disease dynamics within a population; thus, such models are susceptible to human error, unexpected events, or unknown characteristics of a novel infectious agent like COVID-19. We present a relatively non-parametric random forest model that forecasts the number of COVID-19 cases at the U.

Objective: The COVID-19 pandemic initially doubled the rates of food insecurity across the USA and tripled rates among households with children. Despite the association among food insecurity, chronic disease and psychological distress, narratives depicting the experiences of already food insecure populations are notably underrepresented in the literature. The current study assessed the impact of COVID-19 on clients of a food pantry who were also enrolled in the Supplemental Nutrition Assistance Program (SNAP).

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM).

Background: The 'genetic diversity' hypothesis posits that polyandry evolved as a mechanism to increase genetic diversity within broods. One extension of this hypothesis is the 'genetic diversity for disease resistance' hypothesis (GDDRH). Originally designed for eusocial Hymenoptera, GDDRH states that polyandry will evolve as an effect of lower parasite prevalence in genetically variable broods.

On the Design of Social Robots Using Sheaf Theory and Smart Contracts.

Front Robot AI

August 2021

University of Dallas, Gupta College of Business, Irving, TX, United States.

The incorporation of robots in the social fabric of our society has taken giant leaps, enabled by advances in artificial intelligence and big data. As these robots become increasingly adept at parsing through enormous datasets and making decisions where humans fall short, a significant challenge lies in the analysis of robot behavior. Capturing interactions between robots, humans and IoT devices in traditional structures such as graphs poses challenges in the storage and analysis of large data sets in dense graphs generated by frequent activities.

This article presents a hierarchical map of analyses subsumed by canonical correlation and a shiny application to facilitate the connections between said analyses. Building on the work of other researchers who used canonical correlation analyses to unify analyses in the general linear model, we demonstrate that the hierarchy is not as flat as some have portrayed. While a simpler hierarchy may seem to be more accessible, it implies a lack of relationship between analyses that may cause confusion when learning the vast majority of univariate and multivariate analyses in the general linear model.

The advent of checkpoint blockade-based immunotherapy is rapidly changing the management of lung cancer. Whereas past anticancer drugs' primary toxicity was hematologic, the newer agents have primarily autoimmune toxicity. Thus, it is no longer enough for oncology practitioners to be skilled only in hematology.

A Framework for Contractual Graphs.

Front Big Data

March 2021

Gupta College of Business, University of Dallas, Irving, TX, United States.

This paper studies contractual graphs, where the formation of edges between nodes result in dyadic exchanges. Each dyadic exchange is analyzed as a contractual agreement that is implemented upon fulfilment of underlying conditions. As these dyadic exchanges proliferate, the resulting population of these exchanges creates a contractual graph.

The placenta represents a critical node in fetal lipid acquisition, yet the mechanisms by which the placenta handles lipids under normal and pathologic conditions are incompletely understood. A key player in placental lipid handling is peroxisome proliferator-activated receptor gamma (PPARγ). PPARγ influences global gene expression via its regulation of the epigenetic modifier lysine methyltransferase 5A (KMT5A), which places a methyl group on histone 4 lysine 20 (H4K20me) of target genes.

Article Synopsis
  • Bone is always changing and can heal from fractures, and scientists want to understand how to make this healing better.
  • A special type of cell in bone, called Prx1-expressing cells, helps in the healing process, but how they work is still a mystery.
  • Researchers used mice to study how the tiny sensors on these cells (called primary cilia) affect bone healing, and found that without these sensors, bones healed poorly and too slowly.

The popularization of the term "clinical death" for the absence of vital signs suggests the possibility of a radical change in our understanding of death. While death used to be considered something that we do not have the power to reverse, contemporary optimism suggests that we may be able to restore life to a dead organism. In this article, I examine how the term "death" is used today to clarify what kind of irreversibility we ought to assign to it.
