Methods: A retrospective cohort study was conducted, involving 100 consecutive patients who underwent 99mTc-sestamibi single-photon emission computed tomography/computed tomography.

Longitudinal Changes in Patient- and Clinical-Reported Outcomes in Early Spinocerebellar Ataxia Types 1, 2, 3, and 6 from the IDEA Study.

Background: Clinical outcomes assessments (COAs) in spinocerebellar ataxia (SCA) need to be standardized, ataxia-specific, sensitive to change, clinically relevant, and meaningful to patients.

Objectives: To evaluate the longitudinal 1- and 2-year performances of different patient reported outcomes, including the Patient Reported Outcome Measure of Ataxia (PROM-Ataxia), and clinician reported outcomes, including FARS and SARA, in those with early manifest symptoms of SCA 1, 2, 3, and 6.

Methods: We studied 53 patients with early stage SCA1-3 and SCA6 from The Instrumented Data Exchange for Ataxia Study and 24 age-matched healthy controls.

Ibuprofen reduces inflammation, necroptosis and protects photoreceptors from light-induced retinal degeneration.

Background: The retinal degenerative diseases retinitis pigmentosa (RP) and atrophic age- related macular degeneration (AMD) are characterized by vision loss from photoreceptor (PR) degeneration. Unfortunately, current treatments for these diseases are limited at best. Genetic and other preclinical evidence suggest a relationship between retinal degeneration and inflammation.

Ligand-restricted synNotch switches enable precision cell therapy.

Lim and colleagues demonstrate that synNotch transcriptional circuits engineered into T cells can be used to precisely control location-specific expression of payloads responding to antigen triggers, thus locally inhibiting unwanted immunity or neuroinflammation. With no off-tumor toxicity or systemic immunosuppression upon elimination of mouse brain tumors, this approach can achieve better efficacy than anticipated.

The effect of conflicting versus consistent messaging on older women's support for breast cancer screening cessation.

Objective: Breast cancer over-screening is common in older women. Messaging about breast cancer screening cessation may reduce over-screening but the broader informational environment often emphasizes screening continuation. We aimed to examine the effect of receiving consistent messages about breast cancer screening cessation versus conflicting messages (i.

CRM1 regulates androgen receptor stability and impacts DNA repair pathways in prostate cancer, independent of the androgen receptor.

Among the known nuclear exportins, CRM1 is the most studied prototype. Dysregulation of CRM1 occurs in many cancers, hence, understanding the role of CRM1 in cancer can help in developing synergistic therapeutics. The study investigates how CRM1 affects prostate cancer growth and survival.

Policy Recommendations to Support Equitable Access to Long-Acting Injectables for Human Immunodeficiency Virus Prevention and Treatment: A Policy Paper of the Infectious Diseases Society of America and the HIV Medicine Association.

Long-acting injectables (LAIs) for HIV prevention and treatment could dramatically improve health outcomes and health equity for people with HIV and those who could benefit from pre-exposure prophylaxis. Despite widespread acceptability and demand by providers and potential users of LAIs, implementation has been extremely limited since the introduction of cabotegravir/rilpivirine, the first LAI for HIV treatment, in January 2021, and long-acting cabotegravir, the first LAI for HIV prevention, in December 2021. We report results of a provider survey, conducted by the HIV Medicine Association, which identified LAI implementation barriers related to health insurance processes, staffing and administrative support, drug costs and acquisition, and access for individuals who are uninsured.

Evaluating Computerised Assessment of Motor Imitation (CAMI) for identifying autism-specific difficulties not observed for attention-deficit hyperactivity disorder or neurotypical development.

Background: Reliable and specific biomarkers that can distinguish autism spectrum disorders (ASDs) from commonly co-occurring attention-deficit/hyperactivity disorder (ADHD) are lacking, causing misses and delays in diagnosis, and reducing access to interventions and quality of life.

Aims: To examine whether an innovative, brief (1-min), videogame method called Computerised Assessment of Motor Imitation (CAMI), can identify ASD-specific imitation differences compared with neurotypical children and children with ADHD.

Method: This cross-sectional study used CAMI alongside standardised parent-report (Social Responsiveness Scale, Second Edition) and observational measures of autism (Autism Diagnostic Observation Schedule-Second Edition; ADOS-2), ADHD (Conners) and motor ability (Physical and Neurological Examination for Soft Signs).

Chemotherapy in synergy with innate immune agonists enhances T cell priming for checkpoint inhibitor treatment in pancreatic cancer.

Background: The combination of conventional chemotherapy and immune checkpoint inhibitors (ICIs) has been unsuccessful for pancreatic ductal adenocarcinoma (PDAC). Administration of maximum tolerated dose of chemotherapy drugs may have immunosuppressive effects.

Methods: We thus tested, by using the preclinical model of PDACs including the genetically engineered mouse KPC spontaneous pancreatic tumor model and the pancreatic KPC tumor orthotopic implant model, the combinations of synthetic innate immune agonists including STING and NLRP3 agonist, respectively, and ICIs with or without chemotherapy.

Intensive care unit acquired weakness and physical rehabilitation in the ICU.

Approximately half of critically ill adults experience intensive care unit acquired weakness (ICUAW). Patients who develop ICUAW may have negative outcomes, including longer duration of mechanical ventilation, greater length of stay, and worse mobility, physical functioning, quality of life, and mortality. Early physical rehabilitation interventions have potential for improving ICUAW; however, randomized trials show inconsistent findings on the efficacy of these interventions.
