the International Agency for Research on Cancer included the occupational and environmental exposure of firefighters, in the list of carcinogens for humans. ⋯ Identifying associations between firefighters' occupational exposures and cancer risk is a challenging task mainly due to the multifactorial origin of cancer. The best way to reduce exposure is to implement preventative measures.

Case ReportsBeyond the Recommendations of the Clinical Guidelines for Medullary Thyroid Cancer - A Case Report.
Medullary thyroid cancer (MTC) is a rare disease from parafollicular C cells. Calcitonin has been suggested as a screening; its levels are proportional to the tumor size and predictive of metastatic disease. We present a case where an early action was taken with lower cut-off points. ⋯ Surgery was done, and a biopsy confirmed metastases. Conclusions: The clinical guidelines may allow the management of cases; however, they should be used considering each case context. In our patient, if the guidelines had been strictly followed, it would not have been possible to detect liver metastases to achieve a surgical resection with curative intent.

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.
