BACKGROUND AND OBJECTIVE: Addition of darolutamide to androgen deprivation therapy (ADT) and docetaxel significantly improved overall survival (OS) in ARASENS (NCT02799602). Here we report on prostate-specific antigen (PSA) responses and their association with outcomes. METHODS: ARASENS is an international, double-blind, phase 3 study in patients with metastatic hormone-sensitive prostate cancer (mHSPC) randomized to darolutamide 600 mg orally twice daily (n = 651) or placebo (n = 654), both with ADT + docetaxel...

OBJECTIVES: The aim of this study is to audit 7 years of data with a 3 year follow up from a high-volume stone centre performing extracorporeal shock wave lithotripsy (ESWL) to evaluate efficacy in stone clearance compared to existing knowledge and understand reasons for this performance. METHODS: Patients who received ESWL treatment for renal or proximal ureteric stones at a single centre between January 2012 and January 2019 (to allow minimum 3 year follow up) were retrieved...

BACKGROUND: Cryptococcal disease (CD) confers a higher mortality in cirrhotic patients compared to non-cirrhotic patients. Factor association for CD in cirrhotic patients is poorly understood. Our aim was to determine the incidence, demographic, and comorbidities associated with CD among cirrhotic patients in the United States (US). METHOD: Retrospective analysis of admissions of cirrhotic patients, with or without CD, using the National Inpatient Sample (NIS) database from 2005 to 2014...

Declines in bumble bee species range and abundances are documented across multiple continents and have prompted the need for research to aid species recovery and conservation. The rusty patched bumble bee (Bombus affinis) is the first federally listed bumble bee species in North America. We conducted a range-wide population genetics study of B. affinis from across all extant conservation units to inform conservation efforts. To understand the species' vulnerability and help establish recovery targets, we examined population structure, patterns of genetic diversity, and population differentiation...

The use of treated wastewater (TWW) for agricultural irrigation is a critical measure in advancing sustainable water management and agricultural production. However, TWW irrigation in agriculture serves as a conduit to introduce many contaminants of emerging concern (CECs) into the soil-plant-food continuum, posing potential environmental and human health risks. Currently, there are few practical options to mitigate the potential risk while promoting the safe reuse of TWW. In this greenhouse study, the accumulation of 11 commonly occurring CECs was evaluated in three vegetables (radish, lettuce, and tomato) subjected to two different irrigation schemes: whole-season irrigation with CEC-spiked water (FULL), and half-season irrigation with CEC-spiked water, followed by irrigation with clean water for the remaining season (HALF)...

Our study aims to address the challenges in drug development for glioblastoma, a highly aggressive brain cancer with poor prognosis. We propose a computational framework that utilizes machine learning-based propensity score matching to estimate counterfactual treatment effects and predict synergistic effects of drug combinations. Through our in-silico analysis, we identified promising drug candidates and drug combinations that warrant further investigation. To validate these computational findings, we conducted in-vitro experiments on two GBM cell lines, U87 and T98G...

OBJECTIVE: To evaluate the comparative epidemiology of hospital-onset bloodstream infection (HOBSI) and central line-associated bloodstream infection (CLABSI). DESIGN AND SETTING: Retrospective observational study of HOBSI and CLABSI across a three-hospital healthcare system from 01/01/2017 to 12/31/2021. METHODS: HOBSIs were identified as any non-commensal positive blood culture event on or after hospital day 3. CLABSIs were identified based on National Healthcare Safety Network (NHSN) criteria...

Polycystic ovary syndrome (PCOS) is the leading cause of endocrine disorders among females of reproductive age and is linked with autoimmune disorders. PCOS has been associated with autoantibodies such as antinuclear antibody (ANA), anti-thyroid, and anti-Smith (anti-SM). Young patients with PCOS and systemic lupus erythematosus (SLE) have up to a 10-fold increase in stroke. We present a case of a patient with a history of PCOS (on metformin), hypothyroidism, and pulmonary embolism who presented to the emergency room with acute left-sided weakness...

Single case studies of extraordinary disease resilience may provide therapeutic insight into conditions for which no definitive treatments exist. An otherwise healthy 35-year-old man (patient-R) with the canonical pathogenic ACVR1R206H variant and the classic congenital great toe malformation of fibrodysplasia ossificans progressiva (FOP) had extreme paucity of post-natal heterotopic ossification (HO) and nearly normal mobility. We hypothesized that patient-R lacked a sufficient post-natal inflammatory trigger for HO...

OBJECTIVE: Evaluate the effectiveness of alcohol sclerotherapy in postoperative breast and axillary seromas. METHODS: This was an IRB-approved retrospective review of consecutive patients from 2017 to 2021. The procedure involves aspiration of seroma fluid, injection of ethanol for 15 to 30 minutes, and then aspiration of the injected ethanol. Following review of the medical record, patient and procedure data were recorded. Success was defined as no recurrence of seroma...

BACKGROUND: Some human studies have identified infection with cytomegalovirus (CMV), a member of the alpha herpesvirus family, as a risk factor for Alzheimer's disease and related dementias (ADRD). To our knowledge, no studies have evaluated associations of CMV seropositivity with plasma biomarkers of ADRD risk in middle-aged adults. OBJECTIVE: In participants recruited for an exercise study, we evaluated cross-sectional associations of CMV seropositivity with: Aβ42/Aβ40 ratio, a low ratio suggestive of central nervous system Aβ accumulation; glial fibrillary acidic protein (GFAP), a measure of neuroinflammation; and neurofilament light (NfL), a measure of neurodegeneration...

Mosquitoes harbor a wide diversity of microorganisms, including viruses that are human pathogens, or that are insect specific. We used metatranscriptomics, an unbiased high-throughput molecular approach, to describe the composition of viral and other microbial communities in six medically important mosquito species from across Western Australia: Aedes vigilax , Culex annulirostris , Cx. australicus , Cx. globocoxitus , Cx. pipiens biotype molestus , and Cx. quinquefasciatus . We identified 42 viral species, including 13 novel viruses, from 19 families...

Tinnitus acoustic therapy is defined as any use of sound where the intent is to alter the tinnitus perception and/or the reactions to tinnitus in a clinically beneficial way. The parameters of sound that may cause beneficial effects, however, are currently only theorized with limited data supporting their effectiveness. Residual inhibition is the temporary suppression or elimination of tinnitus that is usually observed following appropriate auditory stimulation. Our pilot study investigated the effects of a therapeutic acoustic stimulus that was individually customized to maximize residual inhibition of tinnitus and extend its duration to determine if there could be a sustained suppression of the tinnitus signal (i...

OBJECTIVE: To develop a predictive model for thiamine responsive disorders (TRD) among infants and young children hospitalized with signs or symptoms suggestive of thiamine deficiency disorders (TDD) based on response to therapeutic thiamine in a high-risk setting. STUDY DESIGN: Children aged 21 days to <18 months hospitalized with signs or symptoms suggestive of TDD in northern Lao PDR were treated with parenteral thiamine (100mg daily) for ≥3 days in addition to routine care...

PURPOSE: Time to antibiotic administration (TTA) in <60 minutes for children with neutropenic fever presenting to an emergency room is associated with reduced incidence of sepsis and intensive care admission. As such, TTA is used as a national quality metric for pediatric oncology patients. At our center, in 2020, 19% of the hospitalized patients with a new fever encounter were receiving antibiotics in <60 minutes, prompting a multidisciplinary approach to reach a goal of >90% in all pediatric patients with cancer with a new fever...

Reports of fading vole and lemming population cycles and persisting low populations in some parts of the Arctic have raised concerns about the spread of these fundamental changes to tundra food web dynamics. By compiling 24 unique time series of lemming population fluctuations across the circumpolar region, we show that virtually all populations displayed alternating periods of cyclic/non-cyclic fluctuations over the past four decades. Cyclic patterns were detected 55% of the time ( n = 649 years pooled across sites) with a median periodicity of 3...

Sindbis virus (SINV) is a widely dispersed mosquito-borne alphavirus. Reports of Sindbis disease are largely restricted to northern Europe and South Africa. SINV is frequently sampled in Australian mosquito-based arbovirus surveillance programs, but human disease has rarely been reported. Molecular epidemiological studies have characterized six SINV genotypes (G1-G6) based on E2 gene phylogenies, mostly comprising viruses derived from the African-European zoogeographical region and with limited representation of Australasian SINV...

STUDY DESIGN: Retrospective analysis of prospectively collected data. OBJECTIVE: Evaluate the impact of correcting to normative segmental lordosis values on post-operative outcomes. BACKGROUND: Restoring lumbar lordosis magnitude is crucial in adult spinal deformity surgery, but the optimal location and segmental distribution remains unclear. METHODS: Patients were grouped based on offset to normative segmental lordosis values, extracted from recent publications...
