Introduction: based on the report of a cluster of pneumonia cases of unknown etiology on December 31, 2019 in Wuhan, China, the World Health Organization declared the outbreak to be a public health emergency of international concern; COVID-19 became a pandemic. The process of collecting the sample in the detection of SARS-CoV-2 represents one of the initial and highly relevant stages for carrying out an efficient and robust diagnosis.Objective: to characterize aspects related to the detection of SARS-CoV-2 and the taking of samples in the Province of Villa Clara.Methods: a descriptive, observational, retrospective investigation was carried out with the objective of characterizing aspects related to the detection of SARS-CoV-2 and the taking of samples in the Province of Villa Clara from the 157 confirmed cases with the disease in the period of study.Results: more than half of the cases were taken for bilateral nasal exudate, with a mean threshold cycle of 27.9, with a standard deviation of 7.1. 53.3% of the means of transport corresponded to the Sensure Biotech brand; this type of transport medium was the one with the most samples, with a threshold cycle below 20.Conclusions: the sample with the highest positivity was the bilateral nasal exudate, which coincides with international authors. Of the means of transport evaluated, Sensure Biotech was the one that offered the best results. In the case of asymptomatic patients, the sample that presented the best results was bilateral nasal exudate.

Introduction: Suicide attempts have many meanings and whatever their degree of lethality, special attention should be paid to them.Objective: to characterize the attitude towards negative emotions in parents of adolescents with suicide attempt in the period from January 2018 to December 2019 at the “XX Aniversario” Polyclinic.Methods: descriptive cross-sectional study. Population: 43 families and sample: 15 parents of adolescents with suicide attempt. Several variables were studied: level of education, history of suicide attempt and emotions, etc. Empirical methods were used: participatory observation, documentary analysis, parent questionnaire, in-depth interviews and diagnostic family interviews, and methodological triangulation: indirect and direct methods and the Fredrickson emotions scale.Results: there was a predominance of completed high school education, history of suicide attempt, negative emotions (worry, anger and fear), frequency almost always and with much or enough intensity motivated by: difficulties related to children, family and partner, and the use of inappropriate attitudes: desire to die and lack of control.Conclusions: health care workers should take action to turn the situation around or mitigate the risk factors.

Introduction: gastrointestinal stromal tumor is a rare disease. These tumors originate from the interstitial cells of Ramon y Cajal. The stomach and small intestine are the most frequent sites of localization. Definitive diagnosis is made by immunohistochemical studies.Patient information: a 76-year-old male patient was presented with abdominal pain in the left hypochondrium; a large tumor mass was found in the region. Computed axial tomography showed a tumor-like image at the level of the left hemiabdomen, posterior to the stomach. Surgical intervention was performed to resect the tumor. Pathological studies confirmed gastrointestinal stromal tumor with spindle cell sarcoma pattern.Conclusions: early recognition and adequate investigations are necessary in patients with gastrointestinal symptoms.
