The primary aim was to examine the influence of "quiet time" in critical care. A dual-unit, nonrandomized, uncontrolled trial of a quiet time (QT) protocol was completed. A sample of adult patients from the Neurosciences Intensive Care Unit (NICU) and Cardiovascular Intensive Care Unit (CVICU) participated. Environmental stressors were reduced and patient rest promoted prior to QT. One hundred twenty-nine patients participated in 205 QTs. A one-way, repeated measure analysis of covariance (ANCOVA) was calculated comparing Richards-Campbell Sleep Questionnaire scores, pain and anxiety over three consecutive QTs. No significant statistical effect was found. However, patients rated sleep higher and anxiety levels decreased over consecutive QTs. Ninety-three percent of patients reported QT mattered to them. The combined efforts of nursing, medicine, and ancillary staff are necessary to foster periods of uninterrupted rest, thereby optimizing patient care. Further research is needed to determine if successive QTs positively influence patient outcomes.

Maintaining balance while simultaneously performing other tasks is common during everyday activities. However, this dual-tasking (DT) divides attention and increases cognitive demand, which can be detrimental to stability in older adults. It is unknown if the focus of attention influences how a dual-task affects balance and whether this is detectable in middle-aged adults.

In the present study, we set out to examine the effect of background noise on bilingual language comprehension between a person's first language (L1) and second language (L2). Language control systems seem to systematically engage in bilingual language production, as evidenced by the presence of switch costs with slower responses to switch trials than repeat trials. However, this systematic engagement does not uniformly apply to comprehension, as the involvement of language control in bilingual comprehension may vary depending on external contexts.

In quiet standing, the central nervous system implements a pre-programmed ankle strategy of postural control to maintain upright balance and stability. This strategy comprises a synchronized common neural drive delivered to synergistically grouped muscles. This study evaluated connectivity between EMG signals of the unilateral and bilateral homologous muscle pairs of the lower legs during various standing balance conditions using magnitude-squared coherence (MSC).

Background: Stair climbing tests are pivotal when assessing physical performance in knee osteoarthritis patients, yet the biomechanical strategies that underpin poor stair climbing ability are heterogeneously reported. Single step tasks emulate a step-by-step gait pattern, an approach associated with knee pain when stair climbing. The objective of this study is to analyse the biomechanics and electromyography activity of both the leading and trailing limbs during single Step-up and Down tasks in knee osteoarthritis patients.

Background: Retesting for HIV during pregnancy, labor, and postpartum is crucial for identifying new infections and ensuring timely interventions to prevent mother-to-child transmission (PMTCT). Uganda's national guidelines recommend that pregnant women be retested in the 3rd trimester or during labor/delivery. However, limited information exists regarding adherence to these guidelines, which may affect the effectiveness of PMTCT efforts.
