[Descriptive analysis of 4776 patients admitted to medical clinic services for COVID-19. Results of the Argentine Multi-Center Registry - REMA-COVID-19].

A multicenter registry that included adults hospitalized for COVID-19 was carried out in various provinces of Argentina, from March to October 2020. The objectives were to describe the epidemiological characteristics, clinical manifestations, treatments, complications and risk factors, need for admission to critical care units and mortality. The registry included information on 4776 patients in 37 health centers in Argentina.

[Study of the performance of complex activities of daily living in a population of patients with mild cognitive impairment. Mild functional impairment: A new clinical entity?].

Unlabelled: Several papers describe functional changes in the aging population, and its relevance in the early cognitive impairment detection. Alterations in instrumental activities would constitute a diagnostic marker of MCI and predict the progression to Dementia. In order to count on a tool to evaluate the performance in the use of new technologies we have designed a new protocol, Complex Functional Study (CFS), that quantifies performance and functional changes Related to previous states.

[Prevalence of pain among patients admitted to a clinical hospital].

Background: Pain prevalence during hospital admission is variable, with estimates ranging from 32 to 77%.

Aim: To determine pain prevalence during admission to a clinical hospital.

Material And Methods: Patients admitted to medical and surgical wards were interrogated about the presence of pain within 48 to 72 hours after admission.

Recent respiratory infection predicts atherothrombotic stroke: case-control study in a Buenos Aires healthcare system.

Background And Purpose: Increasing evidence links infections to atherosclerosis. Case-control and cohort studies have found that infections, especially respiratory and dental, are associated with coronary heart disease. However, data on the association of infections with cerebrovascular disease are limited, especially beyond Europe and the United States.

Gait disorders are associated with non-cardiovascular falls in elderly people: a preliminary study.

Background: The association between unexplained falls and cardiovascular causes is increasingly recognized. Neurally mediated cardiovascular disorders and hypotensive syndromes are found in almost 20 percent of the patients with unexplained falls. However, the approach to these patients remains unclear.

Gait velocity as a single predictor of adverse events in healthy seniors aged 75 years and older.

Purpose: Although gait velocity (GV) measurement could predict poor outcomes, few studies regarding its usefulness as a single test in well functioning elderly persons have been pursued. The aim of this study was to asses whether GV could be sufficient to predict adverse events such as hospitalization for any cause, requirement for a caregiver, nursing home placement, falls, fractures, or death in healthy elderly persons.

Methods: Ours was a cohort study comprising 102 well functioning participants aged 75 and older.

Is collectionism a diagnostic clue for Diogenes syndrome?

Background: Diogenes syndrome (DS) is characterized by extreme self-neglect, domestic squalor, and social withdrawal. Despite having been described decades ago, it is still difficult to persue a correct diagnosis in primary care clinics.

Methods: This paper reports a case of an elderly man with extreme self neglect and an abnormal collecting pattern whose condition remained undetected for many years.

[Polymyalgia rheumatica revisited].

Polymyalgia rheumatica is an inflammatory disorder that usually affects persons over the age of 50 causing proximal muscle pain and stiffness, and an elevated erythrocyte sedimentation rate. Although increasingly recognized in this age group, it remains a diagnosis of exclusion and although several diagnostic criteria have been proposed, none has been clearly accepted. While polymyalgia rheumatica is associated with giant cell arteritis, obtaining a temporal artery biopsy is not recommended in patients with polymyalgia rheumatica without symptoms of giant cell arteritis.
