Aging is accompanied by a decline in neovascularization potential and increased susceptibility to ischemic injury. Here, we confirm the age-related impaired neovascularization following ischemic leg injury and impaired angiogenesis. The age-related deficits in angiogenesis arose primarily from diminished EC proliferation capacity, but not migration or VEGF sensitivity.

In 2018, the Veterans Health Administration (VHA) established the original 19 Headache Centers of Excellence (HCoE) program, and an evaluation center. This study utilized a Veteran engagement group method to elicit input from Veteran patients living with chronic headache on daily needs, social determinants of health, and preferences and suggestions for headache programs, services, and research priorities. Four engagement groups were conducted between July 13 and August 22 of 2022 with Veterans who experience headache and received care at a VHA HCoE.

Neural Correlates of Irritability and Potential Moderating Effects of Inhibitory Control.

Biol Psychiatry Glob Open Sci

March 2025

Department of Psychiatry, Vagelos College of Physicians and Surgeons, Columbia University, New York, New York.

Background: Irritability affects up to 20% of youth and is a primary reason for referral to pediatric mental health clinics. Irritability is thought to be associated with disruptions in processing of reward, threat, and cognitive control; however, empirical study of these associations at both the behavioral and neural level have yielded equivocal findings that may be driven by small sample sizes and differences in study design. Associations between irritability and brain connectivity between cognitive control and reward- or threat-processing circuits remain understudied.

Background: Generalized pustular psoriasis (GPP) is a rare, chronic, often unpredictable, severe multisystemic autoinflammatory skin disease from which patients can experience flares, episodes of widespread eruptions of painful, sterile pustules often accompanied by systemic symptoms. The impact of GPP flares and underlying GPP severity on the healthcare resource utilization (HCRU) is not well characterized.

Objective: To quantify HCRU among US GPP patients by flare status and underlying severity.

Pain Perception Threshold in Young High-Altitude Natives After Acute Exposure to Severe Hypoxic Conditions.

Oxygen (Basel)

March 2025

Centro de Investigación en Medicina de Altura (CIMA), Facultad de Medicina Humana, Universidad de San Martín de Porres, Lima 15001, Peru.

Previous studies indicate that individuals at high altitudes have a lower pain threshold than those living at sea level. This study evaluates the differences in pain perception among young people living at an altitude of 3800 m and after acute exposure to a severe hypoxic environment at more than 5100 m. Fourteen people (BMI of 22.

Nationwide Outcomes of Heart Transplantation for Postpartum Cardiomyopathy.

Rev Cardiovasc Med

January 2025

Division of Cardiovascular Medicine, Section of Heart Failure and Transplantation, University of Iowa, Iowa City, IA 52242, USA.

Background: Postpartum cardiomyopathy is defined as an incident of acute heart failure in the postpartum period in the absence of any other cause. Up to 10% of postpartum cardiomyopathy may need to undergo heart transplantation later in life. This study aimed to provide a present-day perspective on all-cause mortality and transplant-related complications after heart transplantation for postpartum cardiomyopathy.

Significance: Functional brain imaging experiments in awake animals require meticulous monitoring of animal behavior to screen for spontaneous behavioral events. Although these events occur naturally, they can alter cell signaling and hemodynamic activity in the brain and confound functional brain imaging measurements.

Aim: We developed a centralized, user-friendly, and stand-alone platform that includes an animal fixation frame, compact peripheral sensors, and a portable data acquisition system.

Introduction: Thoracolumbar kyphosis (TLK) is a frequently reported spinal deformity in achondroplasia, which in combination with the characteristic narrow spinal canal in achondroplasia predisposes for symptomatic spinal stenosis. There is however no consensus on the optimal treatment, due to limited data on diagnostic criteria, the natural development and the prevalence of TLK.

Research Question: This study aims to assess the prevalence, natural development, and diagnostic criteria for pathological TLK in individuals with achondroplasia.

Background And Purpose: Diffusion tensor imaging (DTI) has been proposed to guide the anisotropic expansion from gross tumor volume to clinical target volume (CTV), aiming to integrate known tumor spread patterns into the CTV. This study investigate the potential of using a DTI atlas as an alternative to patient-specific DTI for generating anisotropic CTVs.

Materials And Methods: The dataset consisted of twenty-eight newly diagnosed glioblastoma patients from a Danish national DTI protocol with post-operative T1-contrast and DTI imaging.

Researchers are often faced with evaluating the effect of a policy or program that was simultaneously initiated across an entire population of units at a single point in time, and its effects over the targeted population can manifest at any time period afterwards. In the presence of data measured over time, Bayesian time series models have been used to impute what would have happened after the policy was initiated, had the policy not taken place, in order to estimate causal effects. However, the considerations regarding the definition of the target estimands, the underlying assumptions, the plausibility of such assumptions, and the choice of an appropriate model have not been thoroughly investigated.

Objectives: Infantile hemangioma (IH) is a benign vascular tumor that occurs in 5% of infants, predominantly in female and preterm neonates. Propranolol is the mainstay of treatment for IH. Given the short half-life of propranolol regarding β-adrenergic receptor inhibition as well as its side effects, propranolol is administered to infants 2-3 times daily with 1 mg/kg/dose.

Objective: We aimed to determine whether a pro-inflammatory dietary pattern (mechanism-based diet) is associated with incident female gout among two large cohorts of US women.

Methods: We prospectively followed 79,104 women from Nurses' Health Study (NHS; 1984-2016) and 93,454 women from NHSII (1991-2017); 45,445 men from Health Professionals Follow-up Study (1986-2016) served as a comparison cohort. Validated food frequency questionnaires were used to calculate Empirical Dietary Inflammatory Pattern (EDIP; food-based index predictive of circulating inflammatory biomarkers) scores every 4-years.
