Most HIV-negative individuals exposed to Mycobacterium tuberculosis (Mtb) control infection as latent TB infection (LTBI), but HIV co-infection greatly increases progression to tuberculosis (TB), the leading cause of death in people living with HIV (PLHIV). Although combination antiretroviral therapy (cART) reduces LTBI reactivation, immune control of Mtb is not fully restored, as shown by persistent TB incidence in PLHIV on cART. In macaques, skewed pulmonary effector memory CD4⁺ T-cell (TEM) responses and new TB lesions persist despite cART. We hypothesize that concurrent anti-TB therapy with cART would improve bacterial control and immune restoration compared to cART alone. Using …

BACKGROUND AND OBJECTIVES: Physical abuse is a common cause of morbidity in infants but is often missed in those with medically minor injuries, increasing the risk for escalating violence. Our objective was to compare the prevalence of abuse-specific injuries among infants with and without prior injuries.
METHODS: This is a retrospective, multicenter study of infants (aged < 12 months) undergoing child abuse pediatrics provider (CAP) consultation for suspected physical abuse between 2/2021 and 12/2022 at 10 participating US centers. Encounters were dichotomized into those with and without history of prior injury. The groups were compared for rates of diagnostic screening and prevalence of abuse-specific injuries. The association of prior injuries with identification of abuse-specific injury was assessed using logistic regression controlling for demographics and presence of prior injury.
RESULTS: We identified 2352 eligible encounters (median age: 4.2 months), of which 13% had a history of prior injury. In infants who underwent diagnostic testing, injury identification was significantly higher in those with prior injury (45% vs 22%,
CONCLUSION: Infants with prior injury undergoing …

The morphology of the endoplasmic reticulum (ER), characterized by central sheets and peripheral tubules, is controlled by membrane-shaping proteins. However, the role of lipids in ER morphogenesis remains elusive, despite the ER being the major site for lipid synthesis. Here, by examining the role of eighteen phosphatidic acid (PA)-generating enzymes in ER morphology, we identify lysophosphatidic acid acyltransferase 2 (AGPAT2) as a critical factor in mouse and human cells. AGPAT2 produces PA in the glycerophospholipid/triacylglycerol biosynthesis pathway, and its mutations cause congenital generalized lipodystrophy. We find that AGPAT2-generated PA drives ER tubulation through gene knockout, 3D structural analysis by FIB-SEM, …

Mutations in the tumor suppressor gene TP53 have been identified in breast cancer-associated fibroblasts and are associated with poor patient prognosis. However, the functional impact of fibroblastic mutant p53 on breast cancer development remains unclear. To investigate this, we compared female mice harboring HER2-driven mammary tumors with a fibroblast-specific Trp53 mutation (NP) to those with wild-type fibroblastic Trp53 (N). NP mice exhibited significantly shorter median tumor-free survival than N mice. RNA sequencing of NP and N tumors and mammary glands revealed numerous differentially expressed genes (DEGs) between tumors and the corresponding glands in both genotypes. Notably, the NP tumors showed …

Escalated doses of radiotherapy associate with improved local control and overall survival (OS) in intrahepatic cholangiocarcinoma (iCCA), but personalization remains limited because conventional size-based CT criteria correlate poorly with outcomes. We hypothesized that quantitative enhancement measurements would better predict clinical outcomes and guide individualized RT optimization. In a retrospective cohort of 154 patients, we analyzed pre- and post-RT CT scans using quantitative European Association for Study of Liver (qEASL) to derive viable tumor volumes, comparing enhancement-based metrics with size-based RECIST and linking them to outcomes via survival and mathematical modeling. Change in enhancement volume was strongly associated with OS after …

Abstract
Objective: Hospital-acquired pressure injuries remain a patient safety concern despite standard practice of nurses’ prevention protocols (National Pressure Injury Advisory Panel, 2022). Barriers include: inconsistent two-hour repositioning, documentation burden, inadequate staffing, lack of visual cues of patient risk level, and inconsistent compliance with the overall comprehensive prevention bundle (Agency for Healthcare Research and Quality, 2023).
Aim: HAPIs occur within two adult medical-surgical and telemetry units at a tertiary hospital. In response, staff were surveyed on potential interventions, resulting in the production of a visual cuing system.
Methods: Pre- and post-surveys were conducted on the two medical-surgical units to assess …

Problem There was inconsistency in implementation of the DKA protocol by nurses in the emergency department at the Hospital A. Only 58% of the nurses reported feeling comfortable following the DK protocol, and 84% of the nurses described the DKA order set as confusing. Context Hospital A is a large magnet-recognition hospital system in the Bay Area. The emergency department at Hospital A averages about 12 DKA patients per quarter. Intervention Education sessions were held during pre-shift cuddles across day and night shifts to clarify the DKA protocol and answer any questions or nurses may have. Measures Baseline surveys and …

Background: Computer perception (CP) technologies hold significant promise for advancing precision mental health care systems, given their ability to leverage algorithmic analysis of continuous, passive sensing data from wearables and smartphones (eg, behavioral activity, geolocation, vocal features, and ambient environmental data) to infer clinically meaningful behavioral and physiological states. However, successful implementation critically depends on cultivating well-founded stakeholder trust.
Objective: This study aims to investigate, across adolescents, caregivers, clinicians, and developers, the contingencies under which CP technologies are deemed trustworthy in health care.
Methods: We conducted 80 semistructured interviews with a purposive sample of adolescents (n=20) diagnosed with autism, Tourette …

BACKGROUND: Pharmacy deserts, or areas lacking convenient access to pharmacies, can limit access to medications and reduce adherence. In U.S. cities, pharmacy deserts are disproportionately concentrated in racial/ethnic minority and low-income neighborhoods. This study examined the demographics and spatial distribution of pharmacy deserts in St. Louis City, Missouri, and their associations with sociodemographic and healthcare access determinants.
METHODS: Pharmacy deserts were defined as census tract block groups whose centroids were more than 1 mile from a pharmacy, or more than a half mile and located within a tract where at least 20% of households lacked vehicle access. Demographic and socioeconomic …
