Applications for Laser in Veterinary Dermatology.

Laser usage in veterinary dermatology has increased in popularity over the last several decades. Carbon dioxide (CO) laser is the leading modality in surgical laser for veterinary dermatology because of its unmatched performance with soft tissue, particularly the skin. This laser cuts and coagulates tissue via the photothermal effect of laser energy when interacting with soft tissues with high water content, such as skin.

Distributable, metabolic PET reporting of tuberculosis.

Tuberculosis remains a large global disease burden for which treatment regimens are protracted and monitoring of disease activity difficult. Existing detection methods rely almost exclusively on bacterial culture from sputum which limits sampling to organisms on the pulmonary surface. Advances in monitoring tuberculous lesions have utilized the common glucoside [F]FDG, yet lack specificity to the causative pathogen Mycobacterium tuberculosis (Mtb) and so do not directly correlate with pathogen viability.

Chronic Stress-Induced Neuroinflammation: Relevance of Rodent Models to Human Disease.

The brain is the central organ of adaptation to stress because it perceives and determines threats that induce behavioral, physiological, and molecular responses. In humans, chronic stress manifests as an enduring consistent feeling of pressure and being overwhelmed for an extended duration. This can result in a persistent proinflammatory response in the peripheral and central nervous system (CNS), resulting in cellular, physiological, and behavioral effects.

The Impact of Tuberous Breast on Adolescents: A Cross-sectional Study.

Background: Tuberous breast deformity is a nondiagnostic, descriptive term for a congenital breast difference that becomes apparent at puberty. Although the negative physical and psychosocial effects of macromastia and breast asymmetry are established, no studies to date have explored the impact of tuberous breasts on health-related quality of life (HRQoL) outcomes using a robust sample size.

Methods: In this cross-sectional study, HRQoL surveys were administered to adolescent women with tuberous breasts and healthy female controls, aged 12-21 years.

Intravenous Bacille Calmette-Guérin vaccination protects simian immunodeficiency virus-infected macaques from tuberculosis.

Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), is the most common cause of death in people living with human immunodeficiency virus (HIV). Intra-dermal Bacille Calmette-Guérin (BCG) delivery is the only licensed vaccine against tuberculosis; however, it offers little protection from pulmonary tuberculosis in adults and is contraindicated in people living with HIV. Intravenous BCG confers protection against Mtb infection in rhesus macaques; we hypothesized that it might prevent tuberculosis in simian immunodeficiency virus (SIV)-infected macaques, a model for HIV infection.

Reduction Mammaplasty in Younger Patients: An Evidence-Based Approach to Treatment.

Macromastia is a common condition that can lead to physical pain, emotional burden, and behavioral impairment, with significant decrements in quality of life. Reduction mammaplasty offers the only effective treatment of symptomatic macromastia, and patients experience significant improvements in their physical and psychosocial health through surgical correction. Although symptoms typically arise during adolescence, most women seeking surgical intervention do not undergo reduction mammaplasty until their fifth decade of life.

The Utility of the Schnur Sliding Scale in Adolescent Patients.

Background: Although the Schnur Sliding Scale (SSS) was not intended to be used by third-party payors, it has become the national standard for coverage decisions regarding macromastia treatment in patients of all ages. Adolescents were neither included in the cohort that created the SSS nor represented in subsequent validation studies.

Methods: In this prospective study, health-related quality of life surveys were administered to girls and young women 12 to 21 years of age before and after reduction mammaplasty to treat macromastia.

Influence of a single oral dose of trazodone on intradermal histamine reactivity in clinically healthy dogs.

Background: Drug interactions are significant considerations for intradermal testing (IDT). Trazodone (TRZ) is an anxiolytic and selective histaminergic (H ) antagonist with no interaction in human prick tests; however, interaction in canine IDT is unknown.

Hypothesis/objectives: Trazodone will not adversely affect intradermal histamine reactions in dogs.

Optimizing tuberculosis treatment efficacy: Comparing the standard regimen with Moxifloxacin-containing regimens.

Tuberculosis (TB) continues to be one of the deadliest infectious diseases in the world, causing ~1.5 million deaths every year. The World Health Organization initiated an End TB Strategy that aims to reduce TB-related deaths in 2035 by 95%.

Airway T cells are a correlate of i.v. Bacille Calmette-Guerin-mediated protection against tuberculosis in rhesus macaques.

Bacille Calmette-Guerin (BCG), the only approved Mycobacterium tuberculosis (Mtb) vaccine, provides limited durable protection when administered intradermally. However, recent work revealed that intravenous (i.v.

Voluntary wheel running promotes resilience to the behavioral effects of unpredictable chronic mild stress in male and female mice.

Besides significant benefits to physical health, exercise promotes mental health, reduces symptoms of mental illness, and enhances psychological development. Exercise can offset the impact of chronic stress, which is a major precursor to the development of mental disorders. The effects of exercise on chronic stress-induced behaviors are contradictory in preclinical studies, primarily due to the lack of data and sex-specific investigations.

Vaccination with intravenous BCG protects macaques with pre-existing SIV infection from tuberculosis.

Tuberculosis (TB) is the most common cause of death in people living with HIV. BCG delivered intradermally (ID) is the only licensed vaccine to prevent TB. However, it offers little protection from pulmonary TB in adults.

Host Immunity to Mycobacterium tuberculosis Infection Is Similar in Simian Immunodeficiency Virus (SIV)-Infected, Antiretroviral Therapy-Treated and SIV-Naïve Juvenile Macaques.

Pre-existing HIV infection increases tuberculosis (TB) risk in children. Antiretroviral therapy (ART) reduces, but does not abolish, this risk in children with HIV. The immunologic mechanisms involved in TB progression in both HIV-naive and HIV-infected children have not been explored.

Mental Health Conditions and Health-related Quality of Life Changes after Reduction Mammaplasty in Younger Patients.

Unlabelled: Reduction mammaplasty is increasingly common in younger patients with macromastia. Unfortunately, a recent surge in mental health disorders has been documented in this population. It is unknown how mental health disorders affect patients undergoing reduction mammaplasty.

Risk Factors Associated with Falls and Fractures Following Prescription of Opioids Among Privately Insured Patients with Osteoarthritis.

While prior research has shown that patients with osteoarthritis (OA) who are prescribed opioids have higher rates of falls and fractures following drug initiation, there is a limited body of work establishing a comprehensive model of factors that influence the risk of falls or fractures among these patients. Opioids are associated with negative clinical outcomes, including increased risk of falls and fractures. This study assessed the frequency, treatment characteristics, and risk factors associated with falls or fractures among patients with OA taking opioids.

All-Cause Health Care and Work Loss Burden Associated With Nonsteroidal Anti-Inflammatory Drug and Opioid Treatment in Employed Patients With Osteoarthritis.

Introduction: This study estimated all-cause health care resource utilization (HRU) and costs and work loss outcomes associated with pain management of employed patients with osteoarthritis of the hip and/or knee.

Methods: Optum Health Care Solutions data were analyzed for employed patients prescribed nonsteroidal anti-inflammatory drugs, tramadol, or nontramadol opioids following diagnoses of osteoarthritis of the hip and/or knee. A pre-post design was used to evaluate changes in all-cause HRU and costs, and work loss days and associated costs.

Effectiveness of Preoperative Symptom Screening in Identifying Pediatric SARS-CoV-2 Infections: A Retrospective Cohort Analysis.

Unlabelled: Evidence-based protocols identifying COVID-19 cases in pediatric preoperative settings are lacking. With COVID-19 positioned to remain a threat to children, this study examines effectiveness of preoperative COVID-19 symptom screening in pediatric patients.

Methods: This retrospective cohort study included hospital billing/medical record queries of (1) procedures performed under conscious sedation/general anesthesia and (2) laboratory-confirmed COVID-19 (+) cases from April 6, 2020, to June 15, 2020.

T cell transcription factor expression evolves over time in granulomas from Mycobacterium tuberculosis-infected cynomolgus macaques.

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), is a global health concern, yearly resulting in 10 million new cases of active TB. Immunologic investigation of lung granulomas is essential for understanding host control of bacterial replication. Here, we identify and compare the pathological, cellular, and functional differences in granulomas at 4, 12, and 20 weeks post-infection in Chinese cynomolgus macaques.

Multimodal profiling of lung granulomas in macaques reveals cellular correlates of tuberculosis control.

Mycobacterium tuberculosis lung infection results in a complex multicellular structure: the granuloma. In some granulomas, immune activity promotes bacterial clearance, but in others, bacteria persist and grow. We identified correlates of bacterial control in cynomolgus macaque lung granulomas by co-registering longitudinal positron emission tomography and computed tomography imaging, single-cell RNA sequencing, and measures of bacterial clearance.
