Objective: To determine whether impairments across cognitive and affective domains provide additional information to sensorimotor deficits for fall prediction among various populations.
Design: We pooled data from 5 studies for this observational analysis of prospective falls.
Setting: Community or low-level care facility.
Participants: Older people (N=1090; 74.0±9.4y; 579 female); 500 neurologically intact (NI) older people and 3 groups with neurologic disorders (cognitive impairment, n=174; multiple sclerosis (MS), n=111; Parkinson disease, n=305).
Interventions: None.
Main Outcome Measures: Sensorimotor function was assessed with the Physiological Profile Assessment, cognitive function with tests of executive function, affect with questionnaires of depression, and concern about falling with falls efficacy questionnaires. These variables were associated with fall incidence rates, obtained prospectively over 6-12 months.
Results: Poorer sensorimotor function was associated with falls (incidence rate ratio [95% CI], 1.46 [1.28-1.66]). Impaired executive function was the strongest predictor of falls overall (2.91 [2.27-3.73]), followed by depressive symptoms (2.07 [1.56-2.75]) and concern about falling (2.02 [1.61-2.55]). Associations were similar among groups, except for a weaker relationship with executive impairment in NI persons and a stronger relationship with concern about falling in persons with MS. Multivariable analyses showed that executive impairment, poorer sensorimotor performance, depressive symptoms, and concern about falling were independently associated with falls.
Conclusions: Deficits in cognition (executive function) and affect (depressive symptoms) and concern about falling are as important as sensorimotor function for fall prediction. These domains should be included in fall risk assessments for older people and clinical groups.

Background: Mild Cognitive Impairment (MCI) and Mild Behavioral Impairment (MBI) represent transitional states between normal aging and incipient dementia. We examined whether presence of cognitive complaint (CC), MCI, and MBI differentially predicted risk for all-cause dementia or Alzheimer's disease (AD) in a population-based sample.
Method: Participants included 598 older adults [55% female, with mean (SD) age = 78.
Background: The Mini Mental State Exam (MMSE) is a widely used prescreening tool in dementia research.
Method: Psychometric Raters from two sites within the Alcanza Clinical Research network collected MMSE data from 85 potential subjects who presented for memory trials. Subjects were later screened for Alzheimer's Dementia studies, and the results from subsequent administrations of the Clinical Dementia Rating scale were available for 53 of those subjects.

Background: Traumatic head injuries (THIs) are among the leading cause of mortality and intensive care unit (ICU) admission in children worldwide. Most of the published literature concerning THIs arises predominantly from North America and Europe. However, only limited data about the incidence, characteristics and impact on children in Saudi Arabia exists.

In-situ stress plays a pivotal role in influencing the desorption, adsorption, and transportation of coalbed methane. The reservoir gas content represents a pivotal physical parameter, encapsulating both the coalbed methane enrichment capacity and the underlying enrichment law of the reservoir. This investigation collates, computes, and consolidates data concerning pore pressure, breakdown pressure, closure pressure, triaxial principal stress, gas content, lateral pressure coefficient, and other pertinent variables from coal reservoirs within several coal-bearing synclines in the Liupanshui coalfield, China.

Objective: To evaluate descriptive efficacy data, exploratory immunogenicity data, and safety follow-up through study completion from the global, phase 3 MATISSE (Maternal Immunization Study for Safety and Efficacy) maternal vaccination trial of bivalent respiratory syncytial virus (RSV) prefusion F protein vaccine (RSVpreF).
Methods: MATISSE was a phase 3, randomized, double-blinded, placebo-controlled trial. Healthy pregnant participants aged 49 years or younger at 24-36 weeks of gestation were randomized (1:1) to receive a single RSVpreF 120 micrograms or placebo dose.
