Monocytes and interstitial macrophages contribute to hypoxic pulmonary hypertension.

Hypoxia is a major cause of pulmonary hypertension (PH) worldwide, and it is likely that interstitial pulmonary macrophages contribute to this vascular pathology. We observed in hypoxia-exposed mice an increase in resident interstitial macrophages, which expanded through proliferation and expressed the monocyte recruitment ligand CCL2. We also observed an increase in CCR2+ macrophages through recruitment, which express the protein thrombospondin-1 that functionally activates TGF-beta to cause vascular disease.

Revised Process for ACNS Guidelines Development.

The development of clinical practice guidelines is an evolving field. In response to the need for consistent, evidence-based medical practice, the American Clinical Neurophysiology Society identified the need to update the Society's guideline development process. The American Clinical Neurophysiology Society Guidelines Committee created an action plan with the goal of improving transparency and rigor for future guidelines and bringing existing guidelines to current standards.

Overcoming Hesitancy and Barriers to Care with Integration of Telemedicine in a Free Student-run Health Clinic.

Introduction: Nadezhda Clinic is a free student-run health clinic that provides culturally sensitive primary care services to the underserved Russian-speaking population of the greater Sacramento area. At the onset of the COVID-19 pandemic, the clinic suspended in-person services and solely offered telemedicine visits. Most patients were hesitant to utilize telemedicine due to poor technological literacy, privacy concerns, and a preference for in-person care.

Procedural Prescription Denials and Risk of Acute Care Utilization and Spending Among Medicaid Patients.

Importance: Rising prescription medication costs under Medicaid have led to increased procedural prescription denials by health plans. The effect of unresolved denials on chronic condition exacerbation and subsequent acute care utilization remains unclear.

Objective: To examine whether procedural prescription denials are associated with increased net spending through downstream acute care utilization among Medicaid patients not obtaining prescribed medication following a denial.

Community Racial and Ethnic Representation Among Physicians in US Internal Medicine Residency Programs.

Importance: Increasing underrepresented in medicine (URIM) physicians among historically underserved communities helps reduce health disparities. The concordance of URIM physicians with their communities improves access to care, particularly for American Indian and Alaska Native, Black, and Hispanic or Latinx individuals.

Objectives: To explore county-level racial and ethnic representation of US internal medicine (IM) residents, examine racial and ethnic concordance between residents and their communities, and assess whether representation varies by presence of academic institutions or underserved settings.

Transportation Insecurity, Social Support, and Adherence to Cancer Screening.

Importance: Transportation insecurity and lack of social support are 2 understudied social determinants of health that contribute to excess morbidity, mortality, and acute health care utilization. However, whether and how these social determinants of health are associated with cancer screening has not been determined and has implications for preventive care.

Objective: To determine whether transportation insecurity or social support are associated with screening adherence for colorectal, breast, and cervical cancer.

Adjuvant Atezolizumab for Early Triple-Negative Breast Cancer: The ALEXANDRA/IMpassion030 Randomized Clinical Trial.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.

Willingness to Use Long-Acting Injectable Pre-Exposure Prophylaxis among Adolescent Girls and Young Women in Kampala, Uganda.

Pre-exposure prophylaxis (PrEP) has proven to be a powerful tool in preventing HIV infection. There is limited information about the factors associated with willingness to use different PrEP modalities among adolescent girls and young women (AGYW) in Africa. We assessed willingness to use long-acting injectable PrEP (LAI-PrEP) among 14-24-year-old AGYW at high risk of HIV in Uganda, and associated factors determined using multivariable complementary log-log regression.

A plasmid with the gene enhances the fitness of strains under laboratory conditions.

Antimicrobial resistance (AMR) is a major threat to global public health that continues to grow owing to selective pressure caused by the use and overuse of antimicrobial drugs. Resistance spread by plasmids is of special concern, as they can mediate a wide distribution of AMR genes, including those encoding extended-spectrum -lactamases (ESBLs). The CTX-M family of ESBLs has rapidly spread worldwide, playing a large role in the declining effectiveness of third-generation cephalosporins.

Plasmids encode and can mobilize onion pathogenicity in Pantoea agglomerans.

Pantoea agglomerans is one of four Pantoea species reported in the USA to cause bacterial rot of onion bulbs. However, not all P. agglomerans strains are pathogenic to onion.

Differences in Combustible Cigarette Smoking-Related Biomarkers by Hormonal Contraceptive Use: An Exploratory Study.

Introduction: Hormonal contraceptives (HCs), which contain synthetic forms of estrogen (i.e., ethinyl estradiol) and/or progesterone (i.

Tumor cells upregulate neurotransmitter GABA in the choroid plexus through STAT6-Bestrophin1 signaling, promoting leptomeningeal dissemination.

Background: Leptomeningeal dissemination (LMD) occurs when tumor cells interact with choroid plexus epithelium (CPE) to gain access to cerebrospinal fluid (CSF) in the brain's meninges and ventricular system. This disease is particularly devastating for patients due to our limited understanding and few therapeutic options. The leptomeningeal CSF is a nutritionally deprived microenvironment for tumor cells.

Synthetically Relevant Post-Transition State Bifurcation Leading to Diradical and Zwitterionic Intermediates: Controlling Nonstatistical Kinetic Selectivity through Solvent Effects.

A post-transition state surface intersection (PTSSI) between radical and zwitterionic states that causes a bifurcation in the reaction pathway was discovered through density functional theory calculations on potential energy surfaces and ab initio molecular dynamics simulations of cycloadditions between a bicyclobutane and a triazolinedione (BCB-TAD). It was predicted that changes to the solvent polarity would enable control over the dynamic selectivity in this system; indeed, experimental evidence supported this prediction. This work not only provides new insights into an unusual type of post-transition state bifurcation, but also demonstrates how the nonstatistical dynamic effects that control selectivity for such reactions can be manipulated rationally to increase the yields of synthetically useful reactions.

Pain and Functional Outcome After Microsurgical Decompression of Lumbar Spinal Stenosis: Very Short- and Long-Term Postoperative Analysis.

Study Design: Multicenter, prospective observational cohort study.

Objectives: 109 patients with lumbar spine stenosis (LSS) undergoing minimally invasive decompression in 6 different centers (Germany, Italy, USA).

Methods: The demographic, surgical and clinical data was collected.

Awaiting insurance coverage: Medicaid enrollment and post-acute care use after traumatic injury.

Background: Lack of insurance after traumatic injury is associated with decreased use of postacute care and poor outcomes. Insurance linkage programs enroll eligible patients in Medicaid at the time of an unplanned admission. We hypothesized that Medicaid enrollment would be associated with increased use of postacute care, but also with prolonged hospital length of stay (LOS) while awaiting insurance authorization.

Sickle Cell Trait Does Not Cause "Sickle Cell Crisis" Leading to Exertion-Related Death: A Systematic Review.

Globally, an estimated 300 million individuals have sickle cell trait (SCT), the carrier state for sickle cell disease. While sickle cell disease (SCD) is associated with increased morbidity and shortened lifespan, SCT has a lifespan comparable to that of the general population. However, "sickle cell crisis" has been used as a cause of death for decedents with SCT in reports of exertion-related death in athletes, military personnel, and individuals in police custody.
