Objective: Many patients with ruptured intracranial aneurysms (RIAs) underrepresented or excluded from previous randomized controlled trials (RCTs) comparing surgery with endovascular treatment (EVT) are still considered for surgical clipping, but the best management of these patients remains unknown.
Methods: The International Subarachnoid Aneurysm Trial-2 was a randomized trial comparing surgical versus EVT of RIAs considered for surgical clipping, despite the results of previous RCTs, and also eligible for EVT. The primary endpoint was death or dependency according to the modified Rankin Scale score (mRS score > 2) at 1 year.

Background: The centralization of decision-making power in the public health care system has a negative impact on the practice of professionals and the quality of home care services (HCS) for seniors. To improve HCS, decentralized management could be a particularly promising approach. To be effective, strategies designed to incorporate this management approach require attention to 3 elements: autonomy of local stakeholders, individual and organizational capacities, and accountability for actions and decisions.

The objective of this study was to develop and evaluate a Food Choices Assessment Score (FCAS) measuring alignment with 2019 Canada's Food Guide (CFG) and Canada's Dietary Guidelines (CDG) using a non-quantitative food frequency questionnaire (FFQ) data. Cross-sectional data from the Canadian Health Measures Survey (CHMS) (2016 to 2019), including 6,459 participants (≥19 years) and a non-quantitative FFQ (~100 food items) were used. Content and construct validity and assessing reliability were used to evaluate the FCAS, including a comparison of mean FCAS among Canadian subgroups, calculating the FCAS for high quality diet menus, investigating the consistency of the FCAS with the Dietary Approaches to Stop Hypertension (DASH), as a healthy diet linked with lower cardiometabolic risks, and estimating Cronbach's alpha for reliability.

Franchthi Cave, in the Greek Peloponnese, is a well-known Paleolithic, Mesolithic and Neolithic site, with several human burials. In many parts of Europe there is clear evidence from archaeological and isotopic studies for a diet change between the Mesolithic and Neolithic periods. This is especially the case in coastal contexts where there is often a shift from predominantly marine food diets in the Mesolithic to terrestrial (presumably domesticated) foods in the Neolithic.

Survival analysis is critical in many fields, particularly in healthcare where it can guide medical decisions. Conventional survival analysis methods like Kaplan-Meier and Cox proportional hazards models to generate survival curves indicating probability of survival v. time have limitations, especially for long-term prediction, due to assumptions that all instances follow a general population-level survival curve.

Leydig cells produce hormones that are required for male development, fertility, and health. Two Leydig cell populations produce these hormones but at different times during development: fetal Leydig cells which are active during fetal life and adult Leydig cells that are functional postnatally. Historically, our ability to understand the origin and function of Leydig cells has been made difficult by the lack of genetic models to exclusively target these cells.

Background: Mold plasma cell-free DNA (cfDNA) PCR is a promising non-invasive diagnostic modality for early diagnosis of invasive mold disease (IMD) in immunocompromised patients. Although mold cfDNA PCR has been shown to be highly accurate, the value of invasive procedures to collect specimens for conventional fungal diagnostics following plasma cfDNA testing remains unclear.
Methods: This retrospective single-center cohort study included patients with mold plasma cfDNA PCR performed 7 days before or 2 days after invasive specimen collection.

Here, we used single cell RNA sequencing and single cell spatial transcriptomics to characterize the forebrain neural stem cell (NSC) niche under homeostatic and injury conditions. We defined the dorsal and lateral ventricular-subventricular zones (V-SVZs) as two distinct neighborhoods and showed that, after white matter injury, NSCs are activated to make oligodendrocytes dorsally for remyelination. This activation is coincident with an increase in transcriptionally distinct microglia in the dorsal V-SVZ niche.

People's personality trait levels are often assessed by obtaining self-reports or observer (informant) reports on questionnaires (inventories). When the target person is closely acquainted with the observer-as in the case of spouses, close relatives, or close friends-several findings are obtained for full-length measures of the Big Five (Five-Factor Model) or HEXACO personality factors. First, mean scores tend to be comparable between self-reports and observer reports, although Openness to Experience tends to be higher in self-reports than in observer reports.

People often want to know what their interaction partners are thinking. How accurate are they, what information do they use, what predicts how accurate they will be, and does accuracy matter? We organize our review of thought-feeling accuracy, defined as the accuracy of individuals' judgments about the content of another person's thoughts and feelings in live interaction, around these questions. At the same time, we argue that often people are especially interested in what others are thinking about them, such that research on the accuracy of individuals' metaperceptions regarding others' views of them is highly relevant to understanding thought-feeling accuracy more broadly construed.

The increasing shift from cannabis smoking to cannabis vaping is largely driven by the perception that vaping to form an aerosol represents a safer alternative to smoking and is a form of consumption appealing to youth. Herein, we compared the chemical composition and receptor-mediated activity of cannabis smoke extract (CaSE) to cannabis vaping extract (CaVE) along with the biological response in human bronchial epithelial cells. Chemical analysis using HPLC and GC/MS revealed that cannabis vaping aerosol contained fewer toxicants than smoke; CaSE and CaVE contained teratogens, carcinogens, and respiratory toxicants.

The purpose was to assess whether visual feedback of torque contributes to motor unit (MU) firing rate reduction observed during post-activation potentiation (PAP) of skeletal muscle. From 15 participants 23 MUs were recorded with intramuscular fine-wire electrodes from the tibialis anterior during isometric dorsiflexion contractions at 20% of maximum, with and without both PAP and visual feedback of torque. A 5s maximal voluntary contraction (MVC) was used to induce PAP, and evoked twitch responses were assessed before and after.
