The management of postamputation pain remains a significant clinical challenge, with existing therapeutic approaches often yielding inconsistent outcomes. Neuromodulation techniques, particularly peripheral nerve stimulation (PNS), have emerged as promising interventions. However, the evidence supporting their effectiveness in treating phantom limb pain (PLP) and residual limb pain (RLP) remains limited.

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a "2-hit" model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF.

Background: Individuals with co-occurring posttraumatic stress disorder (PTSD) and HIV are at high-risk for negative HIV-related outcomes, including low adherence to antiretroviral therapy, faster disease progression, more hospitalizations, and almost twice the rate of death. Despite high rates of PTSD in persons with HIV (PWH) and poor HIV-related health outcomes associated with PTSD, an effective evidence-based treatment for PTSD symptoms in PWH does not exist.

Objective: This study aimed to describe the adaptation and theater testing of an evidence-based intervention designed for people with co-occurring PTSD and HIV.

Evidence suggests that bats are important hosts of filoviruses, yet the specific species involved remain largely unidentified. Niemann-Pick C1 (NPC1) is an essential entry receptor, with amino acid variations influencing viral susceptibility and species-specific tropism. Herein, we conducted combinatorial binding studies with seven filovirus glycoproteins (GPs) and NPC1 orthologs from 81 bat species.

Background: Surgical fusion of the sacroiliac (SI) joint is often performed to manage chronic lower back or buttock pain. When Current Procedural Terminology (CPT) codes were introduced, SI joint fusion procedures were done primarily by orthopaedic surgeons and neurosurgeons. The purpose of this study was to examine the utilization of SI joint fusion CPT codes by physician specialty over time.

Objective: Evaluate the relationship of cathepsin-D (CD) on disease severity and clinical outcomes for women with peripartum cardiomyopathy.

Background: Cathepsin-D is a protease released during oxidative stress that cleaves prolactin (PRL) generating a 16 kDa fragment that is pro-apoptotic, anti-angiogenic, and has been implicated in the pathogenesis of peripartum cardiomyopathy (PPCM).

Methods: In 99 women with newly diagnosed PPCM enrolled in the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study, CD levels were assessed by ELISA from serum obtained at study entry.

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Alzheimer's disease (AD)-related dementia preferentially impacts two-thirds of women and one-third of men. The steroidogenic acute regulatory (StAR) protein mediates the biosynthesis of neurosteroids that sustain diverse neuronal activities. Aging, involving neurosteroidal imbalance, is the predominant risk factor for AD causing dementia.

Purpose Of Review: Complex Regional Pain Syndrome (CRPS) is a neuropathic pain disorder characterized by pain disproportionate to the inciting event that is constant for an extended duration. Numerous treatment options for this condition have been explored with unsatisfactory results in many cases. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist typically used as an anesthetic and analgesic, presents a promising potential treatment for CRPS in patients who fail to respond to traditional therapies.

Occipital nerve block for headaches: a narrative review.

J Oral Facial Pain Headache

June 2024

Departments of Anesthesiology and Pharmacology, Toxicology, and Neurosciences, Louisiana State University Health Sciences Center Shreveport, Shreveport, LA 71103, USA.

The occipital nerve block involves the injection of a local anesthetic and possibly a corticosteroid near the occipital nerves at the base of the skull and aims at providing relief from chronic headaches by temporarily numbing or reducing inflammation around the occipital nerves. It has proven to be efficacious in treating chronic headaches, especially those that are refractory to medication; it is both diagnostic and therapeutic with symptom abatement from weeks to months. Occipital nerve blocks can be utilized alone or with standard-of-care therapy for various other headache conditions, such as cluster headaches, episodic headaches or chronic migraines.

Culicoides biting midges adversely impact animal health through transmission of multiple orbiviruses, such as bluetongue virus (BTV). This study used light trapping data collected in the Southeastern United States for three Culicoides midge species that are confirmed or suspected BTV vectors: Culicoides insignis, Culicoides stellifer and Culicoides venustus. Midge presence datasets were combined with meteorological data and ecological data to model habitat suitability for each species.

Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

The VACTERL (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities) association represents an enigmatic syndrome requiring further study. This report describes a full-term neonate born to a multiparous woman who was found, upon further examination, to have multiple congenital abnormalities, including a bicuspid aortic valve, patent foramen ovale, tracheoesophageal fistula (TEF), asymmetric crying facies, microphallus, and a single inguinal testis. The discussion explores environmental and genetic factors that may contribute to this association, as well as similar conditions, such as CHARGE (coloboma, heart defects, choanal atresia, growth retardation, genital abnormalities, and ear abnormalities) syndrome.
