Postural balance and body mass index in older adults; a descriptive and associative study testing traditional risk factors.
There is a scarcity of information about how much the postural balance parameters, as the area and mean velocity of the center of pressure (CoP), can be modified by traditionally adiposity markers in older adults. ⋯ At higher BMI such as at overweight or obesity conditions, older adults show a reduced 'CoP mean velocity' than control normoweight peers', being 'weight' a traditional adiposity risk factor predictor of balance performance.

Controlled Clinical Trial[Metabolic and cardiorespiratory fitness changes in women undergoing a physical exercise program assisted by a mobile application. A non-randomized controlled study].
Metabolic syndrome (MetS) is prevalent in our population. The purpose of this study is to evaluate the effect of physical exercise, assisted by a mobile application (m-Health), on cardiorespiratory fitness (ACR) and cardiovascular risk markers in women with metabolic disorders typical of MetS, and to compare it with the effect of exercise monitored face to face in women with similar characteristics. ⋯ A physical exercise program via m-Health improved ACR and anthropometric parameters in women with cardiometabolic disorders.

Incidence moments: Short term forecast of the COVID-19 incidence rate in Chile.
The predictability of any epidemic is highly uncertain, especially regarding a new emerging pathogen such as SARS-CoV-2. ⋯ The third incidence moment method is suitable for short-term forecasting of COVID-19 with an error of around 30%. This forecast represents a short time of predictability in mainly chaotic dynamics. The predictability decreased only slightly due to pharmacological interventions and the income of new virus variants. We found low predictability in the initial periods of the epidemic and during the Omicron epidemic outbreak.

[Association between Walking Pace and obesity in Chilean Population: Findings from the Chilean National Health Survey 2016-2017].
Walking Pace is a functional marker, used as a predictor of chronic diseases. However, there is a lack of evidence on the association between walking pace and obesity. ⋯ the average and brisk walkingpace was associated with lower body weight, BMI, waist circumference and waist to height ratio and a brisk walking pace was associated with a lower probability of obesity and central obesity, independently of sociodemographic and lifestyle factors.

[Osteosarcoma as a GES-Listed Pathology: 7-Year Experience at a National Reference Center].
Osteosarcoma (OS) is the most frequent malignant primary bone tumor. The explicit health guarantee (GES) plan in Chile, a law that guarantees diagnosis, treatment, and rehabilitation, incorporated OS in 2014. ⋯ This is our country's first demographic description study of patients with OS. In our series, the age of presentation and the presence of metastases at admission were factors that significantly affect prognosis. When adjusting for age, the survival percentages are comparable to those reported in other international centers specialized in sarcomas.
