© The Author(s) 2020.Objectives Regular physical activity for older adults as they age is important for maintaining not only physical function but also independence and self-worth. To be able to monitor changes in physical function, appropriate validated measures are required. Reliability of measures such as the timed-up-and-go, five-repetition sit-to-stand, handgrip strength, two-minute walk, 30-second sit-to-stand, and four-metre walk has been demonstrated; however, the appropriateness of such measures in a population of adults living with dementia, who may be unable to follow instructions or have diminished physical capacity, is not as well quantified. This study sought to test modified standard protocols for these measures. Methods Modification to the standard protocols of the timed-up-and-go, five-repetition sit-to-stand, handgrip strength, two-minute walk, 30-second sit-to-stand, and four-metre walk was trialled. This occurred through modification of procedural components of the assessment, such as encouraging participants reports how modification of the current protocols for common measures of physical function enabled more older adults living with dementia in a residential aged care facility to participate in assessments, with high reliability demonstrated for the measures. © The Author(s) 2020.Measures of handgrip strength can be used to conveniently assess overall muscle strength capacity. Although stand-alone measures of handgrip strength provide robust health information, the clinical meaningfulness to determine prevention and treatment options for weakness remains limited because the etiology of muscle weakness remains unclear. Moreover, clinical outcomes associated with handgrip strength are wide-ranging. Therefore, disentangling how handgrip strength is associated with health conditions that are metabolically or neurologically driven may improve our understanding of the factors linked to handgrip strength. The purpose of this topical review was to highlight and summarize evidence examining the associations of handgrip strength with certain health outcomes that are metabolically and neurologically driven. From this perusal of the literature, we posit that stand-alone handgrip strength be considered an umbrella assessment of the body systems that contribute to strength capacity, and a panoptic measurement of muscle strength that is representative of overall health status, not a specific health condition. Recommendations for future strength capacity-related research are also provided. © The Author(s) 2020.Objectives Extracorporeal membrane oxygenation is a life support procedure developed to offer cardiorespiratory support when conventional therapies have failed. The purpose of this study is to describe the findings during the first years using venoarterial extracorporeal membrane oxygenation in pediatric patients after cardiovascular surgery at Christus Muguerza High Specialty Hospital in Monterrey, Mexico. Methods This is a retrospective, observational, and descriptive study. Caerulein The files of congenital heart surgery post-operative pediatric patients, who were treated with venoarterial extracorporeal membrane oxygenation from January 2013 to December 2015, were reviewed. Results A total of 11 patients were reviewed, of which 7 (63.8%) were neonates and 4 (36.7%) were in pediatric age. The most common diagnoses were transposition of great vessels, pulmonary stenosis, and tetralogy of Fallot. Survival rate was 54.5% and average life span was 6.3 days; the main complications were sepsis (36.3%), acute renal failure (36.3%), and severe cerebral hemorrhage (9.1%). The main causes of death were multi-organ dysfunction syndrome (27.3%) and cerebral hemorrhage (18.2%). Conclusion The mortality rates found are very similar to those found in a meta-analysis report published in 2013 and the main complication and causes of death are also very similar to the majority of extracorporeal membrane oxygenation reports for these kinds of patients. Although the results are encouraging, early sepsis detection, prevention of cerebral hemorrhage, and renal function monitoring must be improved. © The Author(s) 2020.Objectives Hearing aid usage supports communication and independence; however, many do not use their hearing aids. This study explored the experiences of hearing aid use in adults with mild cognitive impairment or Alzheimer's disease. Methods Participants completed semi-structured interviews which were analysed using thematic analysis. Ten people (six males, age range 75-86 years old) with mild cognitive impairment or Alzheimer's disease who had been fitted with hearing aids were recruited to the study. Results We identified four major themes (1) memory and other cognitive barriers to using hearing aids, (2) practical aspects of hearing aids, (3) benefits of hearing aids, and (4) ambivalence towards hearing aids. Conclusions Participants perceived a significant impact of cognitive impairment on the experience of using hearing aids. This population may benefit from targeted strategies to support use of hearing aids. The findings from this study can inform future research to optimise use of hearing aids in this population. © The Author(s) 2020.Background The Rapid Assessment of Hearing Loss (RAHL) survey protocol aims to measure the prevalence and causes of hearing loss in a low cost and rapid manner, to inform planning of ear and hearing services. This paper reports on the first field-test of the RAHL in Gao'an County, Jiangxi Province, China. This study aimed to 1) To report on the feasibility of RAHL; 2) report on the estimated prevalence and causes of hearing loss in Gao'an. Methods A cross-sectional population-based survey was conducted in September-October 2018. Forty-seven clusters in Gao'an County were selected using probability-proportionate-to-size sampling. Within clusters, compact segment sampling was conducted to select 30 people aged 50+. A questionnaire was completed covering sociodemographics, hearing health, and risk factors. Automated pure-tone audiometry was completed for all participants, using smartphone-based audiometry (hearTest), at 0.5, 1, 2, 4 kHz (kHz). All participants had their ears examined by an Ear Nose and Throat (ENT) doctor, using otoscopy, and probable causes of hearing loss assigned.
