Development and validation of an international preoperative risk assessment model for postoperative delirium.

Background: Postoperative delirium (POD) is a frequent complication in older adults, characterised by disturbances in attention, awareness and cognition, and associated with prolonged hospitalisation, poor functional recovery, cognitive decline, long-term dementia and increased mortality. Early identification of patients at risk of POD can considerably aid prevention.

Methods: We have developed a preoperative POD risk prediction algorithm using data from eight studies identified during a systematic review and providing individual-level data.

A forged 'chimera' including the second specimen of the protostegid sea turtle and shell parts of the pleurodire from the Lower Cretaceous Santana Group of Brazil.

Unlabelled: Fossils of Cretaceous sea turtles adapted to an open marine lifestyle remain rare finds to date. Furthermore, the relationships between extant sea turtles, chelonioids, and other Mesozoic marine turtles are still contested, with one key species being Hirayama, 1998, long considered the earliest true sea turtle. The species is an Early Cretaceous member of , a controversial clade either placed within or closely related to or, alternatively, along the stem lineage of hidden-neck turtles () and representing an independent open marine radiation.

Wearable Sensors Reveal Menses-Driven Changes in Physiology and Enable Prediction of the Fertile Window: Observational Study.

Background: Previous research examining physiological changes across the menstrual cycle has considered biological responses to shifting hormones in isolation. Clinical studies, for example, have shown that women's nightly basal body temperature increases from 0.28 to 0.

Modern fertility awareness methods: wrist wearables capture the changes in temperature associated with the menstrual cycle.

Core and peripheral body temperatures are affected by changes in reproductive hormones during the menstrual cycle. Women worldwide use the basal body temperature (BBT) method to aid and prevent conception. However, prior research suggests that taking one's daily temperature can prove inconvenient and subject to environmental factors.

Pulse Rate Measurement During Sleep Using Wearable Sensors, and its Correlation with the Menstrual Cycle Phases, A Prospective Observational Study.

An affordable, user-friendly fertility-monitoring tool remains an unmet need. We examine in this study the correlation between pulse rate (PR) and the menstrual phases using wrist-worn PR sensors. 91 healthy, non-pregnant women, between 22-42 years old, were recruited for a prospective-observational clinical trial.

Data processing for noninvasive continuous glucose monitoring with a multisensor device.

Background: Impedance spectroscopy has been shown to be a candidate for noninvasive continuous glucose monitoring in humans. However, in addition to glucose, other factors also have effects on impedance characteristics of the skin and underlying tissue.

Method: Impedance spectra were summarized through a principal component analysis and relevant variables were identified with Akaike's information criterion.

Validation of human skin models in the MHz region.

The human skin consists of several layers with distinct dielectric properties. Resolving the impact of changes in dielectric parameters of skin layers and predicting them allows for non-invasive sensing in medical diagnosis. So far no complete skin and underlying tissue model is available for this purpose in the MHz range.
