Concomitant Waldenström Macroglobulinemia/Lymphoplasmacytic Lymphoma and Non-Immunoglobulin M Plasma Cell Neoplasm.

Context.—: The co-occurrence of plasma cell neoplasm (PCN) and lymphoplasmacytic lymphoma (LPL) is rare, and their clonal relationship remains unclear.

Objective.

Characteristics and recovery trends of severe TBI patients with a favorable functional outcome at 6-month follow-up.

Traumatic Brain Injury (TBI) is a devastating cause of death and disability. Outcomes following TBI have been extensively studied; however, less attention has been given to identifying characteristics of individuals who have a favorable outcome following severe TBI. We conducted a retrospective analysis of a database containing information on TBI patients admitted to a level 1 trauma center between 2015 and 2021.

Impact of age-related changes in buccal epithelial cells on pediatric epigenetic biomarker research.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.

Gut dysbiosis was inevitable, but tolerance was not: temporal responses of the murine microbiota that maintain its capacity for butyrate production correlate with sustained antinociception to chronic morphine.

The therapeutic benefits of opioids are compromised by the development of analgesic tolerance, which necessitates higher dosing for pain management thereby increasing the liability for drug dependence and addiction. Rodent models indicate opposing roles of the gut microbiota in tolerance: morphine-induced gut dysbiosis exacerbates tolerance, whereas probiotics ameliorate tolerance. Not all individuals develop tolerance, which could be influenced by differences in microbiota, and yet no study design has capitalized upon this natural variation.

Seroprevalence, incidence estimates, and environmental risk factors for dengue, chikungunya, and Zika infection amongst children living in informal urban settlements in Indonesia and Fiji.

Background: The burden of Aedes aegypti-transmitted viruses such as dengue, chikungunya, and Zika are increasing globally, fueled by urbanization and climate change, with some of the highest current rates of transmission in Asia. Local factors in the built environment have the potential to exacerbate or mitigate transmission.

Methods: In 24 informal urban settlements in Makassar, Indonesia and Suva, Fiji, we tested children under 5 years old for evidence of prior infection with dengue, chikungunya, and Zika viruses by IgG serology.

The Calicophoron daubneyi genome provides new insight into mechanisms of feeding, eggshell synthesis and parasite-microbe interactions.

Background: The rumen fluke, Calicophoron daubneyi, is the major paramphistome species infecting ruminants within Europe. Adult flukes reside within the rumen where they are in direct contact with a unique collection of microorganisms. Here, we report a 1.

Case report: Immediate and sustained relief of postherpetic neuralgia with erector spinae nerve block in a 60-year-old woman.

Introduction: The erector spinae plane block (ESPB) is a relatively new regional anesthetic procedure that provides analgesia below the erector spinae muscles in an interfascial plane. The indications for its use continue to expand as we learn more about this block.

Case: We report a case of a 60 year old woman presenting to the emergency department (ED) with severe intractable pain after recent onset of herpes zoster infection.

Clinical outcomes of combined focused shock wave and ultrasound-guided percutaneous irrigation of rotator cuff calcific tendinopathy therapy.

Background: Various conservative treatments have been reported for refractory calcific tendinitis of the shoulder. This study aimed to evaluate the clinical outcomes of a combined therapy of focused shock wave (FSW) and ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT).

Methods: A total of 229 patients (246 shoulders) who experienced shoulder pain for over six months due to calcific tendinitis were included.

Predicting admission for fall-related injuries in older adults using artificial intelligence: A proof-of-concept study.

Aim: Pre-injury frailty has been investigated as a tool to predict outcomes of older trauma patients. Using artificial intelligence principles of machine learning, we aimed to identify a "signature" (combination of clinical variables) that could predict which older adults are at risk of fall-related hospital admission. We hypothesized that frailty, measured using the 5-item modified Frailty Index, could be utilized in combination with other factors as a predictor of admission for fall-related injuries.

Artificial intelligence-enabled safety monitoring in Alzheimer's disease clinical trials.

Background: Investigators conducting clinical trials have an ethical, scientific, and regulatory obligation to protect the safety of trial participants. Traditionally, safety monitoring includes manual review and coding of adverse event data by expert clinicians.

Objectives: Our study explores the use of natural language processing (NLP) and artificial intelligence (AI) methods to streamline and standardize clinician coding of adverse event data in Alzheimer's disease (AD) clinical trials.

Expert opinion on Centiloid thresholds suitable for initiating anti-amyloid therapy. Summary of discussion at the 2024 spring Alzheimer's Association Research Roundtable.

A 24-30 Centiloid (CL) threshold was collectively considered by a group of global dementia experts as a practical and implementable cut-off for anti-amyloid therapy intervention, in Alzheimer's disease patients who have been diagnosed at the mild cognitive impairment or mild dementia stage of their disease. Though additional validation is needed, knowledge of this threshold would be valuable to those involved in diagnosing and treating patients in the new AD care pathways, as well as entry into clinical trials. Therapy monitoring to determine future treatment response and assess amyloid clearance can be accomplished with amyloid PET with some technical details still to be elucidated.

Motor abilities and cognitive performance in Latinos with autosomal dominant Alzheimer's disease.

Background: Declining motor abilities might be a noninvasive biomarker for Alzheimer's disease (AD). Studying motor ability and AD progression in younger Latinos with autosomal dominant Alzheimer's disease (ADAD) can provide insights into the interplay between motor ability and cognition in individuals with minimal confounding from age-normative changes and comorbid medical conditions.

Objectives: This study aimed to (1) examine motor abilities as a function of years to dementia diagnosis and (2) examine associations between motor ability and cognitive performance.

First-in-human phase I trial of the bispecific CD47 inhibitor and CD40 agonist Fc-fusion protein, SL-172154 in patients with platinum-resistant ovarian cancer.

Background: SL-172154 is a hexameric fusion protein adjoining the extracellular domain of SIRPα to the extracellular domain of CD40L via an inert IgG-derived Fc domain. In preclinical studies, a murine equivalent SIRPα-Fc-CD40L fusion protein provided superior antitumor immunity in comparison to CD47- and CD40-targeted antibodies. A first-in-human phase I trial of SL-172154 was conducted in patients with platinum-resistant ovarian cancer.

Expanding access to maggot containment dressings through redesign and innovation.

There are two major styles of maggot debridement dressings: (1) confinement dressings that form a cage around the wound, and (2) containment dressings that completely surround the maggots within a sealed porous bag. For producers and clinicians wanting to prepare containment dressings using readily available polyester bags, it is currently difficult to seal these bags without expensive high-temperature plastic welders. This study aimed to identify simple and affordable methods for sealing maggots within polyester net bags.

Comparison of Clinical and Radiological Outcomes of Three-Column Lumbar Osteotomies with and without Interbody Cages for Adult Spinal Deformity.

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.

Prevalence and Patterns of Social Media Use in Early Adolescents.

Objective: To describe patterns of social media use, including underage (under 13 years) use and sex differences, in a diverse, national sample of early adolescents in the U.S.

Methods: We analyzed the social media use data in the Adolescent Brain Cognitive Development Study (2019-2021, Year 3), which includes a national sample of early adolescents in the U.

A lipidated peptide derived from the C-terminal tail of the vasopressin 2 receptor shows promise as a new β-arrestin inhibitor.

β-arrestins play pivotal roles in seven transmembrane receptor (7TMR) signalling and trafficking. To study their functional role in regulating specific receptor systems, current research relies mainly on genetic tools, as few pharmacological options are available. To address this issue, we designed and synthesised a novel lipidated phosphomimetic peptide inhibitor targeting β-arrestins, called ARIP, which was developed based on the C-terminal tail (A343-S371) of the vasopressin V2 receptor.

We surveyed academic radiology leaders about their views on AI and how they intend to approach AI implementation in their departments.

Materials And Methods: We conducted a web survey of Society of Chairs of Academic Radiology Departments (SCARD) members between October 5 and October 31, 2023 to solicit optimism or pessimism about AI, target use cases, planned implementation, and perceptions of their workforce.

Statistical harmonization of versions of measures across studies using external data: self-rated health and self-rated memory.

Purpose: Harmonizing variables for constructs measured differently across studies is essential for comparing, combining, and generalizing results. We developed and fielded a brief survey to harmonize Likert and continuous versions of measures for two constructs, self-rated health and self-rated memory, for use in studies of French older adults.

Methods: We recruited 300 participants from a French memory clinic in 2023 to answer both the Likert and continuous versions of self-rated health and self-rated memory questions.

Effect of mass drug administration on malaria incidence in southeast Senegal during 2020-22: a two-arm, open-label, cluster-randomised controlled trial.

Background: In Africa, the scale-up of malaria-control interventions has reduced malaria burden, but progress towards elimination has stalled. Mass drug administration (MDA) is promising as a transmission-reducing strategy, but evidence from low-to-moderate transmission settings is needed. We aimed to assess the safety, coverage, and effect of three cycles of MDA with dihydroartemisinin-piperaquine plus single, low-dose primaquine on Plasmodium falciparum incidence and prevalence in southeast Senegal.

Spotted fever group rickettsiae in black rats, pets, and humans in Zungarococha community, A rural area in the surroundings of Iquitos, Peru.

Rickettsiae are a family of ectoparasite-borne bacteria that can produce high morbidity and mortality among humans. There are scarce data on rickettsial ecology in rural areas of the Peruvian Amazon basin, where seroprevalence has not been determined, and the identities of animals acting as reservoirs of these bacteria are not known. We conducted a cross-sectional study in Zungarococha (between 2019 and 2021), a rural community located approximately 20 km away from Iquitos city.

When less is more: Short-Term efficacy of a gamified personalized normative feedback intervention for college students.

Despite various intervention efforts, college drinking remains a concern, and while personalized normative feedback (PNF) has proven effective, attempts to deliver it in a way that minimizes reactance and maximizes student engagement have been slow to emerge. This study examined the short-term effects of CampusGandr, a mobile gamified PNF intervention for college students. The game took place over 16 weeks (1 round per week) during the fall semester and included weekly PNF on various topics related to college life, including alcohol.
