Objective: To develop age-appropriate nonaGEnaRIan And cenTenarian suRgICal (GERIATRIC) risk tool for classifying patients who may or may not develop postoperative complications or die within their index hospital admission.
Background: There are no validated perioperative risk stratification tools for use in nonagenarian and centenarian patients-people aged 90 to 99 years and >100 years.
Methods: In this retrospective observational study, nonagenarians and centenarians undergoing any surgical procedure were profiled.
The Europa Imaging System (EIS) consists of a Narrow-Angle Camera (NAC) and a Wide-Angle Camera (WAC) that are designed to work together to address high-priority science objectives regarding Europa's geology, composition, and the nature of its ice shell. EIS accommodates variable geometry and illumination during rapid, low-altitude flybys with both framing and pushbroom imaging capability using rapid-readout, 8-megapixel (4k × 2k) detectors. Color observations are acquired using pushbroom imaging with up to six broadband filters.

- This study examined how social determinants of health (SDoH) impact HPV-positive oropharyngeal squamous cell cancers (OPSCC) in different sexes, analyzing data from 2010 to 2018.
- The researchers found that male patients, especially those who are Black or from lower socioeconomic backgrounds, experienced delays in treatment and worse mortality rates compared to females, especially Black females.
- The study highlights significant disparities driven by social factors, emphasizing the need for tailored healthcare strategies and policies to address these issues in HPV-positive OPSCC patients.
Introduction: Sepsis is the leading cause of child death worldwide, with the majority of these deaths occurring in low- and middle-income countries (LMICs). The aim of this systematic review and meta-analysis was to describe clinical prognostic scores and models for pediatric sepsis outcomes and assess the performance of these scores for predicting mortality in LMICs.
Methods: Ovid Medline, CINAHL, Cochrane Library, EBSCO Global Health, and Web of Science, were searched through September 2022 for citations related to the development or validation of a clinical prognostic score or model among children with sepsis, conducted in LMIC.
There is ample evidence that individual-level cognitive mechanisms active during language learning and use can contribute to the evolution of language. For example, experimental work suggests that learners will reduce case marking in a language where grammatical roles are reliably indicated by fixed word order, a correlation found robustly in the languages of the world. However, such research often assumes homogeneity among language learners and users, or at least does not dig into individual differences in behavior.
