Assessing infectiousness and the impact of effective treatment to guide isolation recommendations for people with pulmonary tuberculosis.

Determining the extent and duration of infectiousness of individuals with pulmonary tuberculosis (TB) is critical for various aspects of TB care, including decisions regarding isolation. Studies suggest considerable heterogeneity in infectiousness of people with pulmonary TB. Pre-treatment, measures of bacillary burden including sputum smear microscopy, culture time-to-positivity, and Xpert MTB/RIF cycle threshold (Ct) value, predict the risk of transmission to contacts.

Causes of Pediatric Deaths in Lusaka, Zambia: A Quantitative Geographic Information Systems Approach.

Background: While childhood mortality has been declining in Zambia, it remains high at 58 per 1000 live births. Importantly, many leading causes of mortality in Zambia are preventable. This study was conducted to identify clusters of childhood mortality, causes of death of recently deceased children, barriers to care, and risk factors for mortality in Lusaka, Zambia.

Executive Function and Adherence in Children and Adolescents Living with HIV: Evidence from the HIV-associated Neurocognitive Disorders in Zambia (HANDZ) Study.

Introduction: Executive function (EF) may be impaired in people with human immunodeficiency virus (HIV) infection, and poor EF may affect medication adherence. However, there is little data on EF in children with HIV in sub-Saharan Africa.

Methods: 208 children/adolescents with perinatally acquired HIV and 208 HIV-exposed uninfected controls were recruited in Zambia for this prospective cohort study.

Medical Psychiatry Units: A Delphi Consensus Approach to Defining Essential Characteristics.

Medical psychiatry units (MPUs), also known as complexity intervention units, represent an important innovation for integrating medical and behavioral health care in the hospital setting, thereby reducing the need for sequential medical and psychiatric hospitalization. As US hospitals face an increased demand for mental health services, interest in the MPU model is gaining momentum. However, there is no shared definition for what constitutes an MPU, and significant variation exists among units across the United States that have been designated as an MPU.

The effect of YOCAS©® yoga on cancer-related fatigue and quality of life in older (60+) vs. younger (≤ 59) cancer survivors: Secondary analysis of a nationwide, multicenter, phase 3 randomized controlled trial.

Introduction: Older cancer survivors consistently express the need for interventions to reduce cancer-related fatigue (CRF) and maintain quality of life (QOL). Yoga is a promising treatment to address CRF and QOL. However, research comparing the efficacy of yoga for improving fatigue and QOL in older survivors (60+) vs.

A scalable two-stage Bayesian approach accounting for exposure measurement error in environmental epidemiology.

Accounting for exposure measurement errors has been recognized as a crucial problem in environmental epidemiology for over two decades. Bayesian hierarchical models offer a coherent probabilistic framework for evaluating associations between environmental exposures and health effects, which take into account exposure measurement errors introduced by uncertainty in the estimated exposure as well as spatial misalignment between the exposure and health outcome data. While two-stage Bayesian analyses are often regarded as a good alternative to fully Bayesian analyses when joint estimation is not feasible, there has been minimal research on how to properly propagate uncertainty from the first-stage exposure model to the second-stage health model, especially in the case of a large number of participant locations along with spatially correlated exposures.

Personalized outcomes in neuropathic pain: a clinical relevance and assay sensitivity analysis from a randomized controlled trial.

Objective: To explore the clinical relevance and assay sensitivity of using personalized outcomes using data from a randomized clinical trial (RCT) in people with chemotherapy-induced peripheral neuropathy (CIPN).

Design: This study is a secondary analysis that leveraged data from a RCT of transcutaneous electrical stimulation for CIPN to test whether personalized outcomes could minimize potential floor effects and increase the assay sensitivity of pain clinical trials (ie, ability to detect a true treatment effect).

Setting: Participants were recruited for a RCT from community oncology clinics in the United States.

Strength of activation and temporal dynamics of bioluminescent-optogenetics in response to systemic injections of the luciferin.

BioLuminescent OptoGenetics ("BL-OG") is a chemogenetic method that can evoke optogenetic reactions in the brain non-invasively. In BL-OG, an enzyme that catalyzes a light producing reaction (i.e.

COVID-19-Associated Hospitalizations Among U.S. Adults Aged ≥18 Years - COVID-NET, 12 States, October 2023-April 2024.

Among adults, COVID-19 hospitalization rates increase with age. Data from the COVID-19-Associated Hospitalization Surveillance Network were analyzed to estimate population-based COVID-19-associated hospitalization rates during October 2023-April 2024 and identify demographic and clinical characteristics of adults aged ≥18 years hospitalized with COVID-19. Adults aged ≥65 years accounted for 70% of all adult COVID-19-associated hospitalizations, and their COVID-19-associated hospitalization rates were higher than those among younger adult age groups.

Electrostatically embedded symmetry-adapted perturbation theory.

Symmetry-adapted perturbation theory (SAPT) is an ab initio approach that directly computes noncovalent interaction energies in terms of electrostatics, exchange repulsion, induction/polarization, and London dispersion components. Due to its high computational scaling, routine applications of even the lowest order of SAPT are typically limited to a few hundred atoms. To address this limitation, we report here the addition of electrostatic embedding to the SAPT (EE-SAPT) and ISAPT (EE-ISAPT) methods.

Reduction of Pediatric Gastrostomy Tube Healthcare Utilization and Socioeconomic Disparities: Longitudinal Benefits of Quality Improvement.

Background: Disparities in emergency department (ED) utilization after gastrostomy (G-) tube placement were previously demonstrated at our children's hospital. We aimed to reduce postoperative G-tube dislodgements and ED visits with a particular focus on socially vulnerable children.

Methods: Our improvement team implemented a G-tube care bundle (6/2018-9/2019) targeting caregiver preparedness and standardizing care in the pre-, intra-, and post-operative periods.

Is Information About Musculoskeletal Malignancies From Large Language Models or Web Resources at a Suitable Reading Level for Patients?

Background: Patients and caregivers may experience immense distress when receiving the diagnosis of a primary musculoskeletal malignancy and subsequently turn to internet resources for more information. It is not clear whether these resources, including Google and ChatGPT, offer patients information that is readable, a measure of how easy text is to understand. Since many patients turn to Google and artificial intelligence resources for healthcare information, we thought it was important to ascertain whether the information they find is readable and easy to understand.

Palliative Care Acceptability for Older Adults with Advanced CKD: A Qualitative Study of Patients and Nephrologists.

Rationale & Objective: Older adults in the United States often receive kidney therapies that do not align with their goals. Palliative care (PC) specialists are experts in assisting patients with the goals of care discussions and decision support, yet views and experiences of older patients who have received PC while contemplating kidney therapy decisions and their nephrologists remain unexplored. We evaluated the acceptability of CKD-EDU, a PC-based kidney therapy decision support intervention for adults ≥75 years of age.

Autism is associated with in vivo changes in gray matter neurite architecture.

Postmortem investigations in autism have identified anomalies in neural cytoarchitecture across limbic, cerebellar, and neocortical networks. These anomalies include narrow cell mini-columns and variable neuron density. However, difficulty obtaining sufficient post-mortem samples has often prevented investigations from converging on reproducible measures.
