CONCLUSIONS: This trial builds upon formative work to evaluate the effectiveness, implementation, and cost of a peer-delivered, stepped care intervention integrated into primary care. A stepped-care design to maximize optimal use of resources and integration into primary care is a necessary step to increase accessible intervention programs for people with HIV with comorbid SUD globally.

INTRODUCTION: Neuropathic pain is one of the most common and debilitating complications following spinal cord injury (SCI), frequently surpassing motor and sensory deficits as the symptom patients most want treated. Despite advances in understanding the molecular and physiological mechanisms underlying central neuropathic pain, effective treatments remain lacking and show wide variability in efficacy. Previous reports have indicated that early intervention represents the most effective pain...

DEK is an estrogen-responsive chromatin-remodeling protein broadly expressed in the murine and human brain, with high expression in memory-relevant regions such as the hippocampus. Prior work from our group and others has linked DEK loss to cellular features associated with Alzheimer's disease and Alzheimer's disease-related dementias. Notably, our group has demonstrated that DEK expression declines with increasing dementia severity in women, but not in age-matched men, suggesting a sex-specific...

Sickle cell trait (SCT) is a genetic condition characterized by a heterozygous A-T substitution (Glu to Val) in 1 copy of the β-globin (HBB) gene on chromosome 11. Although often asymptomatic, individuals with SCT can experience complications under stress, such as hypoxia, dehydration, and extreme exertion, leading to vaso-occlusion, organ damage, and impaired immune defenses. Understanding the impact of SCT on the immune system may aid in preventing clinical complications. We genotyped 720...

CONCLUSION: This case highlights the unique airway management challenges posed by intratracheal tumors located near the carina and underscores the importance of meticulous pre-procedural planning, anticipation of complications, and readiness for emergency airway interventions during bronchoscopic treatment. Even minimally invasive procedures such as cryotherapy may lead to life-threatening airway compromise when tumors are located in critical central airway regions.

Current guidelines acknowledge the importance of both microsurgical and neuroendovascular expertise in the treatment of cerebrovascular disease. To achieve optimal care for these patients, it is becoming increasingly evident that procedural volumes impact patient outcomes. This is demonstrated across various cerebrovascular diseases.In this literature review, we demonstrate the association of volume with patient outcomes across multiple cerebrovascular disease states and interventions....

Dengue virus (DENV) and chikungunya virus (CHIKV) co-circulate in many regions and present with overlapping clinical features, which complicate accurate diagnosis and disease management. This study develops an integrative transcriptomic framework to identify robust host gene signatures that distinguish between dengue, chikungunya, and healthy states. Publicly available RNA sequencing (RNA-seq) datasets derived from human blood samples were analyzed using a cross-validation design to ensure...

CONCLUSION: ICP monitoring was associated with increased mortality and worse discharge outcomes in patients with sTBI. Increased mortality was largely mediated by WLST. These results question the effectiveness of ICP-guided management and highlight the major impact that decisions to WLST have on treatment effects and patient outcomes.

Bi-directional maternal-fetal exchange during pregnancy creates a long-term microchimerism (Mc) legacy in both individuals, but its presence and cellular fate in human brain are largely unknown. We studied surgically resected epilepsy brain specimens with targetable maternal polymorphisms using polymorphism-specific quantitative PCR. Maternal Mc was prevalent, detectable in 70% of patients, and often at striking quantities spanning temporal, frontal, parietal, and hippocampal regions. Next, we...

CONCLUSIONS: Patients demonstrated immediate reduction in pain but delayed improvement in SC and ODI score. Among preoperative assessments, only SCs were predictive of postoperative outcomes. Furthermore, pain scores did not correlate with disability or activity. SC demonstrated interquartile stability, suggesting that SC may provide a reliable and independent perspective and may be predictive of outcomes.

Death certificates record causes of death as reported by certifiers (Entity Axis) and as standardized by mortality coding rules (Record Axis). Conventional statistics reduce these to a single underlying cause, ignoring other contributing conditions; weighting schemes can instead distribute the burden across all listed causes. We evaluated reclassification from Entity to Record axis and weighting across all 56,986,831 US death certificates from 2003 to 2023, mapping International Classification...

Quantum computers require both high-fidelity operations and large qubit numbers to surpass classical capabilities¹. Trapped-ion platforms have demonstrated the highest gate fidelities of any modality^(2-6) but scaling to larger qubit numbers while preserving performance has remained a central challenge. We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture⁷. Helios features ^(137)Ba^(+) hyperfine qubits^(8,9),...

CONCLUSIONS: Our findings suggest that current methods of clinical identification of B-ICP episodes may not reliably distinguish true episodes of sustained ICP for the most common B-ICP episode type. We suggest developing open-source, real-time, temporally synchronized electronic B-ICP episode definition methods to direct future treatment and research.

Ceramide, a central hub in sphingolipid metabolism, serves as a critical bioactive signalling mediator that integrates lipid metabolism with multiple signalling pathways, primarily promoting autophagy and apoptosis. It influences female reproductive homeostasis and pathophysiology through multiple dimensions: altered ceramide levels have been observed in various reproductive disorders-such as polycystic ovary syndrome (PCOS), premature ovarian insufficiency (POI) and endometriosis (EM)-as well...

Acquired hemophilia A is a rare autoimmune bleeding disorder caused by neutralizing autoantibodies against factor VIII. It typically affects older adults and may present with spontaneous mucocutaneous bleeding, extensive ecchymoses, soft-tissue hematomas, and isolated prolongation of the activated partial thromboplastin time. We report the case of an 84-year-old woman with hypertension, hyperlipidemia, and anxiety who presented with several weeks of spontaneous nontraumatic bruising, fatigue,...

CONCLUSION: BA reduced early postoperative moderate-to-severe CRBD and rescue medication use after URSL. BA may be a safe, non-pharmacological adjunct for acute postoperative CRBD management.

CONCLUSION: ECA-to-V3 VA bypass with atlantoaxial decompression is a safe and effective surgical option for patients with medically refractory VBI, offering durable symptom control and a low risk of neurological complications. Although postoperative neck discomfort is not uncommon, the overall safety profile and efficacy of the procedure support its consideration in carefully selected patients.
