Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.

Incidence, presentation, and outcomes of intracranial hemorrhage in left ventricular assist device patients.

Objective: The objective was to evaluate the etiology, natural history, and impact of surgical intervention on outcomes of left ventricular assist device (LVAD) patients presenting with intracranial hemorrhage (ICH).

Methods: The authors completed a retrospective review of LVAD patients who presented with ICH at 2 centers between 2013 and 2022. Patients were reviewed for demographic, clinical, and radiographic variables.

Methods And Materials: Consecutive patients were enrolled between March and August 2020.

Salt Sensitivity of Blood Pressure and the Role of the Immune System in Hypertension.

Salt-sensitive blood pressure is a clinical phenotype defined as exaggerated blood pressure responses to salt loading and salt depletion. This characteristic occurs in 25% of the general population and 50% of patients with hypertension and contributes to the pathogenesis of hypertension in some patients. Hypertension is associated with chronic inflammatory responses and has immune cell accumulation in several hypertensive target organs, including the brain, kidneys, heart, blood vessels, and the perivascular adipose tissue, and these cellular responses likely exacerbate hypertension.

Dyspnea, dysfunctional breathing disorders, and the Bayesian brain hypothesis.

Clinicians frequently evaluate patients who present with dyspnea. This term describes uncomfortable breathing during physical activity, and the intensity or degree of dyspnea can vary in an individual depending on circumstances and between individuals. In some cases, the level of dyspnea appears out of proportion to other information relevant to the cardiorespiratory system, and this situation has been described as dysfunctional breathing.

Understanding the multidimensionality of a concern for falling in people with unilateral transtibial amputation: a cross-sectional study.

People with lower limb loss often experience psychological concerns related to falling. A concern for falling (CFF) includes four subdomains: fear of falling, self-efficacy, consequences of falling, and perceptions of falls. Limited research exists on how these subdomains are influenced by clinical factors and falls history.

Resveratrol natural product inspired compound as a potent neuroprotectant against acute oxidative stress.

Resveratrol as well as natural products biosynthetically derived from it, have been shown to have protective effects against oxidative stress. However, these compounds possess poor druglike properties. At sub-nanomolar concentrations, a novel compound (RVM-6) inspired by a resveratrol natural product prolongs synaptic viability in neuromuscular junctions in exposed to acute oxidative stress.

Comparing the Diagnostic Yield of Germline Exome Versus Panel Sequencing in the Diverse Population of the Texas KidsCanSeq Pediatric Cancer Study.

Purpose: To evaluate the relative diagnostic yield of clinical germline genomic tests in a diverse pediatric cancer population.

Patients And Methods: The KidsCanSeq study enrolled pediatric cancer patients across six sites in Texas. Germline analysis included both exome sequencing and a therapy-focused pediatric cancer gene panel.

Vasopressor-Inotropic Score: Review of Literature.

Patients undergoing cardiac surgery often receive vasopressor and inotropic medications during the surgical procedure and during intensive care unit (ICU) management following surgery. Patients with cardiogenic shock, septic shock, and other clinical disorders associated with shock also receive vasopressor medications during their ICU care. The level of support and the duration of support are likely associated with outcomes, including mortality and new organ dysfunction, such as acute kidney injury.

An Analysis of Tobacco and Marijuana Use by Middle School and High School Bisexual and Homosexual Students Surveyed by the National Youth Tobacco Survey From 2020 to 2022.

Objectives: This study aimed to analyze tobacco and marijuana use by middle and high school students identifying as bisexual, gay, lesbian, or heterosexual using data from the National Youth Tobacco Survey (NYTS) spanning from 2020 to 2022. By comparing substance use patterns among different sexual orientation groups, the study sought to identify disparities and potential socioeconomic factors influencing these behaviors.

Methods: Data from the 2020 to 2022 NYTS were analyzed, focusing on responses regarding ever use of cigarettes, e-cigarettes, and marijuana by students of varying sexual orientations.

Stereotactic Magnetic Resonance-Guided Daily Adaptive Radiation Therapy for Localized Prostate Cancer: Acute and Late Patient-Reported Toxicity Outcomes.

Purpose: To report acute and late bowel, urinary, and sexual dysfunction patient-reported outcome measures, among patients with localized prostate cancer who underwent stereotactic magnetic resonance-guided daily adaptive radiation therapy (SMART).

Methods And Materials: All patients who completed a baseline 12-item Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events questionnaire, before undergoing SMART with 36.25 Gy in 5 fractions, were subsequently followed up with the same graded questionnaire at set time points.

Combat Medics' Preparedness to Serve as Behavioral Health Extenders in Forward Environments.

Introduction: Future multidomain operational combat environments will require combat medics to play a larger role in managing behavioral health (BH) conditions in forward environments, as soldiers in small teams may have them as their sole medical support for extended periods of time. Previously they were not expected to serve in this role, and thus, they receive minimal BH training. It is unknown to what extent combat medics consider BH tasks as falling within their scope of practice and how often they engage with their soldiers currently related to BH.

Dyspnea and long COVID patients.

Patients with prior COVID-19 infections often develop chronic post-COVID symptoms, such as fatigue and dyspnea. Some patients have residual pulmonary disorders with abnormal pulmonary function tests and/or chest radiographs to explain their dyspnea. However, other patients appear to have dyspnea that is out of proportion to any measurable change in lung function.

Analysis of the Types of Retracted COVID-19 Articles Published in PubMed-Listed Journals.

Objectives: Periodically, medical publications are retracted. The reasons vary from minor situations, such as author attributions, which do not undermine the validity of the data or the analysis in the article, to serious reasons, such as fraud. Understanding the reasons for retraction can provide important information for clinicians, educators, researchers, journals, and editorial boards.

Splenic artery embolization complicated by pleural effusion.

This case report and review describes a 31-year-old man with a history of chronic pancreatitis who presented to the hospital with shortness of breath and left-sided chest pain. Three days prior, he underwent mid-splenic artery embolization due to hematemesis attributed to a splenic artery pseudoaneurysm associated with a peripancreatic pseudocyst. Upon this presentation, the patient reported increasing shortness of breath, left-sided pleuritic chest pain, and epigastric and left upper quadrant abdominal pain.

Stereotactic Magnetic Resonance-Guided Daily Adaptive SABR (SMART) for Localised Non-Metastatic Pancreatic Cancer: First Reported Clinical Outcomes From the UK.

Aims: Prognosis of locally advanced pancreatic cancer (LAPC) remains poor with limited therapeutic options. Radiation therapy in pancreatic cancer has been restricted by the disease's proximity to radiosensitive organs at risk (OAR). However, stereotactic magnetic resonance-guided adaptive radiation therapy (SMART) has demonstrated promise in delivering ablative doses safely.
