9105) or gender (P=.2169). Older subjects (age ≥65) had worse hearing outcomes than younger subjects after initial device activation (age <65, P=.0262). There was no significant difference in rate of hearing loss over time between older and younger patients (P=.0938). Initial postoperative hearing loss was not associated with the rate of long-term hearing loss.

Long-term low frequency hearing preservation is possible for CI recipients and is not associated with gender or device type. Rate of hearing loss over time is not dependent on patient age. Early hearing loss after CI does not predict the rate of long-term hearing loss.

While the cerebellum is traditionally known for its role in sensorimotor control, emerging research shows that particular subregions, such as right Crus I (RCrusI), support language and social processing. Indeed, cerebellar atypicalities are commonly reported in autism spectrum disorder (ASD), a neurodevelopmental disorder characterized by socio-communicative impairments. However, the cerebellum's contribution to early socio-communicative development remains virtually unknown.

Here, we characterized functional connectivity within cerebro-cerebellar networks implicated in language/social functions in 9-month-old infants who exhibit distinct 3-year socio-communicative developmental profiles. We employed a data-driven clustering approach to stratify our sample of infants at high (n = 82) and low (n = 37) familial risk for ASD into three cohorts-Delayed, Late-Blooming, and Typical-who showed unique socio-communicative trajectories. We then compared the cohorts on indices of language and social development. Sehe cerebellum is implicated in prediction, our findings point to probabilistic learning as a potential intermediary mechanism that may be disrupted in infancy, cascading into alterations in social communication.
We show that hypoconnectivity within distinct cerebro-cerebellar networks in infancy predicts altered socio-communicative development before delays overtly manifest, which may be relevant for early detection and intervention. As the cerebellum is implicated in prediction, our findings point to probabilistic learning as a potential intermediary mechanism that may be disrupted in infancy, cascading into alterations in social communication.
Pregnancy is a risk factor for the progression of diabetic retinopathy (DR) in women with pre-gestational diabetes. Australian screening guidelines recommend DR screening in the first trimester of pregnancy. The rates of DR screening in pregnant patients with pre-gestational diabetes are unknown in Australia.

To determine the rates of DR screening in pregnant women with pre-gestational diabetes at Alice Springs Hospital Diabetes Antenatal Care and Education (DANCE) clinic.

Retrospective review of women with pre-gestational diabetes who attended the DANCE clinic between July 2016 and June 2020.

There were 146 pregnancies in 144 individual women included in this review. There were 93% (n=134) who identified as Aboriginal but not Torres Strait Islander. 2-deoxyglucose DR screening was performed in 23 (16%) pregnancies, in which DR was present in six (26%) and no retinal abnormality was found in 17 (74%). Of seven (5%) women who had a history of DR, only three had a screen during the pregnancy period. The location of the DR screen included Alice Springs Hospital (17%, n=4), Alice Springs general practice clinics (35%, n=8) and remote NT community clinics outside of Alice Springs (39%, n=9). The trimesters in which women received their DR screens were trimester 1, 45%, n=10; trimester 2, 39%, n=9; trimester 3, 17%, n=4.

The minority of pregnant women who attend the DANCE clinic at Alice Springs Hospital received DR screening in adherence with national guidelines.

Recently, poor response to oral terbinafine has been reported. We have summarized the most appropriate dosing regimens of posaconazole, fosravuconazole, voriconazole, and oteseconazole (VT-1161) to treat onychomycosis and superficial fungal infections. A structured search on PubMed and Google Scholar was conducted. Additionally, the bibliographies of selected articles were searched to identify relevant records. The number of records identified from the searches was 463, with 50 articles meeting the inclusion criteria for review. None of the new azoles are US FDA approved for onychomycosis treatment; however, an increasing number of studies have evaluated these agents. The efficacies (complete cure and mycologic cure) of the antifungal agents for dermatophyte great toenail onychomycosis treatment are terbinafine 250 mg/day × 12 weeks (Phase III trial) (38%, 70%), itraconazole 200 mg/day × 12 weeks (Phase III trial) (14%, 54%), posaconazole 200 mg/day × 24 weeks (Phase IIB) (54.1%, 70.3%), fosravuconazole 100 mg/day ravuconazole equivalent × 12 weeks (Phase III) (59.4%, 82.0%), and oteseconazole 300 mg/day loading dose × 2 weeks (Phase II), followed by 300 mg/week × 10 weeks (maintenance dose) (45%, 70%). Guidelines for monitoring are also presented.
Prehospital identification of large vessel occlusion (LVO) holds significant potential to decrease the onset-to-treatment time. Several prehospital scales have been developed to identify LVO but data on their comparison has been limited. The aim of this study was to review the currently available prehospital LVO scales and compare their performance using prehospital data.

All patients transported by ambulance using stroke code on a six-month period were enrolled into the study. The prehospital patient reports were retrospectively evaluated by two investigators using sixteen LVO scales identified by literature search and expert opinion. After the evaluation, the computed tomography angiography results were reviewed by a neuroradiologist to confirm or exclude LVO.

Sixteen different LVO scales met the predetermined study criteria and were selected for further comparison. Using them, a total of 610 evaluations were registered. The sensitivity of the scales varied between 8%-73%, specificity between 71%-97% and overall accuracy between 71%-87%. The areas under curve (AUC) varied between 0.61-0.80 for the whole scale range and 0.53%-0.74 for the scales' binary cut-offs. The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) was the only scale with AUC>0.8. Regarding scales' binary cut-offs, The FAST-ED (0.70), Gaze - Face Arm Speech Time (G-FAST) (0.74) and Emergency Medical Stroke Assessment (EMSA) (0.72) were the only scales with AUC>0.7.

In a comparison of 16 different LVO scales, the FAST-ED, G-FAST and EMSA achieved the highest overall performance.

Macrophage infiltration and activation is a critical step during acute colitis. Redox-mediated activation of NLRP3 inflammasomes in macrophages plays a critical role in mediating colonic inflammatory responses. Rhein isolated from the rhizome of rhubarb exhibits anti-inflammatory effects in various diseases. However, its role in regulating acute colonic inflammation is unexplored. Here, we investigated the protective mechanisms of rhein during acute gut inflammation and its regulation of macrophage activation.

Inhibitory effects of rhein on NLRP3 inflammasomes were evaluated in activated macrophages and a mouse model of colitis. Expression of inflammatory mediators, inflammasome complex and redox-related signalling were analysed by ELISA, Western blots, immunofluorescence staining, and qRT-PCR. The phenotype of macrophages was assessed by flow cytometry. Colonic inflammation was evaluated by histological analysis.

Rhein significantly decreased IL-1β secretion via NLRP3 inflammasomes by disturbing their mising strategy of novel compounds for regulating mucosal inflammation in gastrointestinal disorders.The apical junctional complex (AJC) is a membrane protein ultrastructure that regulates cell adhesion and homeostasis. The tight junction (TJ) and the adherens junction (AJ) are substructures of the AJC. The interplay between TJ and AJ membrane proteins to assemble the AJC remains unclear. We employed synthetic biology strategies to express the basic membrane elements of a simple AJC-the adhesive extracellular domains of junctional adhesion molecule A (JAM-A), epithelial cadherin, claudin 1, and occludin-to study their interactions. Our results suggest that calcium concentration fluctuations and JAM-A, acting as an interface molecule between the TJ and AJ, orchestrate their interplay. Calcium affects the secondary structure, oligomerization, and binding affinity of homotypic and heterotypic interactions of TJ and AJ components, thus acting as a molecular switch influencing AJC dynamics.
Racial disparities in the uptake of cancer genetic services are well documented among African American (AA) women. Understanding the multiple social and psychological factors that can influence the uptake of genetic testing among AA women is needed.

Data came from 270 AA women diagnosed with ovarian cancer and participating in a population-based, case-control study of ovarian cancer who were asked about genetic testing. Logistic regression analyses tested the associations of predisposing, enabling, and need factors with reported genetic testing uptake.

One-third of the sample (35%) reported having had genetic testing. In the multivariable model, AA women with higher incomes had more than double the odds of being tested than those with the lowest income (odds ratio [OR] for $25,000-$74,999, 2.04; 95% confidence interval [CI], 1.06-3.99; OR for ≥$75,000, 2.32; 95% CI, 0.92-5.94). AA women who reported employment discrimination were significantly less likely to report genetic testing than those who did notrimination decreased the likelihood of testing. These results provide foundational evidence supporting the need for interventions to improve the uptake of genetic testing among AA women by reducing cost barriers and providing credible assurances that genetic results will be kept private and not affect social factors such as employability.
Enfortumab vedotin (EV) is a novel antibody-drug conjugate approved for advanced urothelial cancer (aUC) refractory to prior therapy. In the Urothelial Cancer Network to Investigate Therapeutic Experiences (UNITE) study, the authors looked at the experience with EV in patient subsets of interest for which activity had not been well defined in clinical trials.

UNITE was a retrospective study of patients with aUC treated with recently approved agents. This initial analysis focused on patients treated with EV. Patient data were abstracted from chart reviews by investigators at each site. The observed response rate (ORR) was investigator-assessed for patients with at least 1 post-baseline scan or clear evidence of clinical progression. ORRs were compared across subsets of interest for patients treated with EV monotherapy.

The initial UNITE analysis included 304 patients from 16 institutions; 260 of these patients were treated with EV monotherapy and included in the analyses. In the monotherapy cohort, the ORR was 52%, and it was >40% in all reported subsets of interest, including patients with comorbidities previously excluded from clinical trials (baseline renal impairment, diabetes, and neuropathy) and patients with fibroblast growth factor receptor 3 (FGFR3) alterations.
