Psychometric properties of ability to contribute measurements as a domain of functional ability of older persons: a COSMIN systematic review.

Background: Older person's ability to contribute covers contributions divided into five subdomains: assisting friends and neighbours, mentoring peers and younger people, caring for family, engaging in the workforce and voluntary activity.

Objective: To evaluate the psychometric properties of ability to contribute measurements as a domain of functional ability of older persons using Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology for systematic reviews.

Methods: A systematic search was performed in PubMed, Embase and PsycINFO databases, for observational studies published within the last 10 years.

Introduction: Historical Development and Progression of Clinical Research on Ageing.

Research on ageing has developed since Greek times. It had a very slow advance during the Middle Ages and a big increase in the Renaissance. Darwin contributed somehow to the understanding of the ageing process and initiated a cumulus of ageing explications under the name of Evolutionary Theories.

Association of loneliness and social isolation with all-cause mortality among older Mexican adults in the Mexican health and aging study: a retrospective observational study.

Background: Plenty of evidence shows how social isolation and loneliness are associated with increased risk for numerous diseases and mortality. But findings about their interactive or combined effects on health outcomes and mortality remains inconclusive.

Objective: Analyze the longitudinal association of loneliness, social isolation and their interactions, with the all-cause mortality among older adults in Mexico.

Acute kidney injury secondary to chlorine dioxide use for COVID-19 prevention.

Chlorine dioxide has been historically used as a disinfecting agent for drinking water supplies and surfaces. Widespread use as an alternative option for prevention and treatment of COVID-19 has emerged due to a lack of specific treatment. We present the case of a 55-year-old male who developed acute kidney injury and disseminated intravascular coagulation after chlorine dioxide prophylactic ingestion, with regression after therapy with hemodialysis.

Mortality and associated risk factors for older adults admitted to the emergency department: a hospital cohort.

Background: Older emergency department patients are more vulnerable than younger patients, yet many risk factors that contribute to the mortality of older patients remain unclear and under investigation. This study endeavored to determine mortality and factors associated with mortality in patients over 60 years of age who were admitted to the emergency departments of two general hospitals in Mexico City.

Methods: This is a hospital cohort study involving adults over 60 years of age admitted to the emergency department and who are beneficiaries of the Mexican Institute of Social Security and residents of Mexico City.

A Frailty Index from Next-of-Kin Data: A Cross-Sectional Analysis from the Mexican Health and Aging Study.

To construct a frailty index from next-of-kin information of the last year of life of community-dwelling 50 years old or older adults and test its association with health services utilization. Cross-sectional analysis from next-of-kin data available from the last wave of the Mexican Health and Aging Study (MHAS). Along with descriptive statistics, the frailty index (FI) was tested in regression models to assess its association with adverse outcomes previous to death: number of hospitalized days in the previous year and number of visits to a physician in the previous year, in unadjusted and adjusted models.

Acute kidney injury in cardiac surgery.

Introduction: Acute kidney injury (AKI) associated with cardiac surgery is a common postoperative complication that increases the morbidity and mortality substantially. However, there is limited information of AKI after cardiac surgery in our institution.

Material And Methods: We conducted a prospective, observational, and longitudinal analysis of adult patients that underwent to cardiac surgery requiring cardiopulmonary bypass and aortic cross clamp.
