The Autonomic Nervous System (ANS)-Immune Network in People Living With HIV.

Purpose Pre-clinical studies have demonstrated direct influences of the autonomic nervous system (ANS) on the immune system. However, it remains unknown if connections between the peripheral ANS and immune system exist in humans and contribute to the development of chronic inflammatory disease. This study had three aims: 1.

Diffusion tensor imaging with free-water correction reveals distinctions between severe and attenuated subtypes in Mucopolysaccharidosis type I.

Mucopolysaccharidosis type I (MPS I) is an inherited lysosomal storage disorder leading to deleterious brain effects. While animal models suggested that MPS I severely affects white matter (WM), whole-brain diffusion tensor imaging (DTI) analysis was not performed due to MPS-related morphological abnormalities. 3T DTI data from 28 severe (MPS IH, treated with hematopoietic stem cell transplantation-HSCT), 16 attenuated MPS I patients (MPS IA) enrolled under the study protocol NCT01870375, and 27 healthy controls (HC) were analyzed using the free-water correction (FWC) method to resolve macrostructural partial volume effects and unravel differences in DTI metrics accounting for microstructural abnormalities.

Predicting Antidepressant Treatment Response From Cortical Structure on MRI: A Mega-Analysis From the ENIGMA-MDD Working Group.

Accurately predicting individual antidepressant treatment response could expedite the lengthy trial-and-error process of finding an effective treatment for major depressive disorder (MDD). We tested and compared machine learning-based methods that predict individual-level pharmacotherapeutic treatment response using cortical morphometry from multisite longitudinal cohorts. We conducted an international analysis of pooled data from six sites of the ENIGMA-MDD consortium (n = 262 MDD patients; age = 36.

Deep transcranial magnetic stimulation for adolescents with treatment-resistant depression: Behavioral and neural correlates of clinical improvement.

Background: Affective bias toward negativity is associated with depression and may represent a promising treatment target. Stimulating the dorsolateral prefrontal cortex (dlPFC) with deep Transcranial Magnetic Stimulation (dTMS) could lead to shifts in affective bias. The current study examined behavioral and neural correlates of affective bias in the context of dTMS in adolescents with treatment-resistant depression (TRD).

Radiation Myelitis Risk After Hypofractionated Spine Stereotactic Body Radiation Therapy.

Importance: Stereotactic body radiation therapy (SBRT) for spinal metastases improves symptomatic outcomes and local control compared to conventional radiotherapy. Treatment failure most often occurs within the epidural space, where dose is constrained by the risk of radiation myelitis (RM). Current constraints designed to prevent RM after spine SBRT are derived from limited data.

The NExT trial: Protocol for a two-phase randomized controlled trial testing transcranial magnetic stimulation to augment exposure therapy for youth with OCD.

Background: Exposure with Response Prevention (ERP) is a first-line treatment for OCD, but even when combined with first-line medications it is insufficiently effective for approximately half of patients. Compulsivity in OCD is thought to arise from an imbalance of two distinct neural circuits associated with specific subregions of striatum. Targeted modulation of these circuits via key cortical nodes (dorsolateral prefrontal cortex [dlPFC] or presupplementary motor area [pSMA]) has the potential to improve ERP efficacy by decreasing compulsions during therapy.

Normative modeling of brain MRI data identifies small subcortical volumes and associations with cognitive function in youth with fetal alcohol spectrum disorder (FASD).

Aim: To quantify regional subcortical brain volume anomalies in youth with fetal alcohol spectrum disorder (FASD), assess the relative sensitivity and specificity of abnormal volumes in FASD vs. a comparison group, and examine associations with cognitive function.

Method: Participants: 47 children with FASD and 39 typically-developing comparison participants, ages 8-17 years, who completed physical evaluations, cognitive and behavioral testing, and an MRI brain scan.

Investigating the Role of Soybean Genetic Resistance on the Production of Sclerotia.

Sclerotia serve as survival structures for many plant pathogens, including Sclerotinia sclerotiorum, which causes Sclerotinia stem rot (SSR) in soybeans and leads to significant yield losses. While partially resistant soybean varieties are effective in reducing SSR incidence, the relationship between resistance and sclerotial production remains unclear. This study investigated the sclerotial production of two soybean recombinant inbred lines (RILs) with differential levels of SSR resistance under both greenhouse and field conditions.

Procalcitonin-guided antibiotic treatment in patients with cancer: a patient-level meta-analysis from randomized controlled trials.

Background: Use of serum procalcitonin (PCT), an inflammatory biomarker for bacterial infections, has shown promising results for early stopping antibiotic treatment among patients with respiratory infections and sepsis. There is need for additional data regarding effectiveness and safety of this concept among patients with cancer.

Methods: Individual data of patients with a documented diagnosis of cancer and proven or suspected respiratory infection and/or sepsis were extracted from previous trials where adult patients were randomized to receive antibiotic treatment based on a PCT protocol or usual care (control group).

Microbiological trends, in-hospital outcomes, and mortality in infective endocarditis: a Swiss-nationwide cohort study.

Background: The epidemiology of infective endocarditis (IE) is evolving, driven by an aging population and increased use of endovascular devices, and is associated with significant morbidity and mortality. This study aims to evaluate changes in microbiological trends and clinical outcomes in patients with IE over the past decade in Switzerland.

Methods: This nationwide cohort study analyzed in-hospital claims data from patients hospitalized with IE in Switzerland between 2012 and 2021.

Association of phenylalanine and tyrosine metabolism with mortality and response to nutritional support among patients at nutritional risk: a secondary analysis of the randomized clinical trial EFFORT.

Background: Elevated phenylalanine serum level is a surrogate marker of whole-body proteolysis and has been associated with increased mortality in critically ill patients. Tyrosine is a metabolite of phenylalanine and serves as a precursor of thyroid hormones and catecholamines with important functions in the oxidative stress response among others. Herein, we examined the prognostic significance of phenylalanine, tyrosine, as well as its metabolites nitrotyrosine, L-3,4-dihydroxyphenylalanine (DOPA), and dopamine regarding clinical outcomes and response to nutritional therapy in patients at nutritional risk.

Outcomes and Complications After Elective Thoracic and Lumbar Spinal Fusion in Elderly Patients: A Comparison of Methods to Predict Adverse Events.

Study Design: Retrospective study.

Objectives: The current study compares the ability of the modified Frailty Index (mFI), the American Society of Anesthesiologists (ASA) classification, the modified Charleston Comorbidity Index (mCCI), the American College of Surgeons Surgical Risk Calculator (SRC), and the Fusion Risk Score (FRS) to predict perioperative outcomes.

Methods: Comorbidity indices were calculated for patients undergoing elective thoracic and lumbar spinal fusion at a single institution and assessed for their discriminative ability in predicting the desired outcomes using an area under the curve (AUC) analysis.

Autonomic and Immune Stress Response Networks in Patients Living With HIV.

Background And Objectives: Stress response systems are frequently dysregulated in patients with chronic inflammatory disorders. Pre-clinical studies have demonstrated direct influences of the sympathetic and vagal/parasympathetic branches of the autonomic nervous system (ANS) on the immune system. However, these connections have not been examined in humans.

Accelerated Partial Breast Irradiation for Early-Stage Invasive Lobular Carcinoma.

Purpose: Invasive lobular carcinoma (ILC) represents 10% to 15% of invasive breast cancers with limited representation among trials of accelerated partial breast irradiation (APBI). Contemporary guidelines advise against treating ILC with APBI given a paucity of supportive evidence. Here, we evaluated oncologic outcomes among patients with ILC treated with APBI.

Coral high molecular weight carbohydrates support opportunistic microbes in bacterioplankton from an algae-dominated reef.

Unlabelled: High molecular weight (HMW; >1 kDa) carbohydrates are a major component of dissolved organic matter (DOM) released by benthic primary producers. Despite shifts from coral to algae dominance on many reefs, little is known about the effects of exuded carbohydrates on bacterioplankton communities in reef waters. We compared the monosaccharide composition of HMW carbohydrates exuded by hard corals and brown macroalgae and investigated the response of the bacterioplankton community of an algae-dominated Caribbean reef to the respective HMW fractions.

The Impact of a Creativity Camp Intervention on Depression and Well-Being in Adolescents.

Depression is a serious public health problem that often emerges during adolescence. Many adolescents do not respond to standard treatments, necessitating the development of novel interventions. We conducted a preliminary study to assess the impact of a novel creative arts intervention on depression and well-being in adolescents.

Gastrointestinal Dysmotility, Autonomic Function and Small Intestinal Bacterial Overgrowth Among People with Well-Controlled HIV.

Introduction: Gastrointestinal dysfunction, including microbiome changes and increased translocation across a compromised gastrointestinal barrier plays a role in the chronic inflammation experienced by people with HIV (PWH). It is unknown whether autonomic neuropathy (AN) may contribute to these mechanisms by altering gastrointestinal motility.

Methods: This is a cross-sectional study of 100 PWH and 89 controls.

Pharmacokinetic Research in Pediatric Extracorporeal Therapies: Current State and Future Directions.

Extracorporeal life support (ECLS), including extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT), are life-saving therapies for critically ill children. Despite this, these modalities carry frustratingly high mortality rates. One driver of mortality may be altered drug disposition due to a combination of underlying illness, patient-circuit interactions, and drug-circuit interactions.

Sex differences in clinical presentation, treatment response, and side effects of nutritional therapy among patients at nutritional risk: a secondary analysis of the randomized clinical trial EFFORT.

Background: Considering sex-specific factors has become an increasingly recognized area for research and practice, in the field of clinical nutrition, there is insufficient evidence regarding differences in clinical presentation, treatment response, and side effects of nutritional therapy among female and male patients.

Objectives: We hypothesized that the clinical presentation, response to nutritional therapy, and side effects from the intervention would differ in the two sexes.

Methods: This secondary analysis investigated differences among female and male patients at risk for malnutrition regarding initial presentation, clinical outcomes, and treatment response in patients included in the Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), a randomized controlled trial comparing individualized nutritional support to usual care.

Extravascular lung water assessment by lung ultrasound in infants following pediatric cardiac surgery.

Background: Lung edema is a significant factor in prolonged mechanical ventilation and extubation failure after cardiac surgery. This study assessed the predictive capability of point-of-care Lung Ultrasound (LUS) for the duration of mechanical ventilation and extubation failure in infants following cardiac procedures.

Methods: We conducted a prospective observational trial on infants under 1 year, excluding those with pre-existing conditions or requiring extracorporeal membrane oxygenation.

Hospitalization Trends for Airway Infections and In-Hospital Complications in Cleft Lip and Palate.

Importance: Cleft lip or palate is a prevalent birth defect, occurring in approximately 1 to 2 per 1000 newborns and often necessitating numerous hospitalizations. Specific rates of hospitalization and complication are underexplored.

Objective: To assess the rates of airway infection-associated hospitalization, overall hospital admissions, in-hospital complications, and mortality among children with a cleft lip or palate.

Association of leucine and other branched chain amino acids with clinical outcomes in malnourished inpatients: a secondary analysis of the randomized clinical trial EFFORT.

Background: The essential branched-chain amino acids leucine, isoleucine and valine are considered anabolic and stimulate protein synthesis in the muscles as well in the liver. They also promote muscle recovery and contribute to glucose homeostasis. Recent studies in critically ill patients have demonstrated that depletion of plasma leucine is associated with increased mortality, but data in the non-critical care setting is lacking.
