Introduction: population aging is one of the most important phenomenon of the 21st century. Research on this subject is becoming more and more necessary every day. Objective: to determine the risk factors associated with overload in informal caregivers of prostrate older adults in the health area of Cacocum, Holguín, year 2022. Method: a cross-sectional descriptive observational study was carried out in Cacocum, Holguín, from July 5, 2021 to August 29, 2022. A total of 129 caregivers of prostrate older adults (N?129) were selected as the study´s universe and the sample consisted of 106 informal caregivers (n?106), obtained by nonprobability purposive sampling. The Zarit Scale was used to determine factors associated with overload in caregivers. Variables studied were as follow: age, sex, educational level, daily hours dedicated to caregiving, relationship between the caregiver and the patient, and the manifestation of overload in caregivers. Results: there was predominance in the age group of 60 to 69 years and female sex. Caregivers with twelfth grade of education and manifestation of overloaded were predominant. There was a predominance of caregivers with family ties and a significant relationship with overload. Predominated caregivers who spent an average of 18 hours per day in the care of the patients and the caregivers who had spent 3 to 4 years in caregiving, a significant relationship with overload was found. Conclusions: the relationship established between the caregivers and patients in terms of filial relationship and the years spent in the care provided to the patient were the factors most associated with the development of overload.

Introduction: tibioperoneal syndesmosis injuries are frequent both in isolation or associated with posterior malleolus fractures. Clinical diagnosis is confirmed on imaging studies. Fixation methods might be rigid or dynamic as well. Objective: provide new aspects related to tibioperoneal syndesmosis injuries in terms of diagnosis, fixation methods and the use of arthroscopic procedure. Method: search and analysis of information needed were carried out in a period of 61 days (from October 1 to November 30, 2022) and the following words were used: syndesmosis injury, ankle syndesmosis instability, syndesmosis instability AND tight rope ankle instability, posterior maleolar fracture. Based on the information obtained, a bibliographic review of the total of 258 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the search engine and reference manager EndNote. Development: it was expressed in the study aspects related to clinical management used in diagnostic and classification on the types of CT scan for fracture associated with posterior malleolar fracture. The rigid and dynamic fixation methods and its characteristics were mentioned as well. The arthroscopic approaches and its advantages for both diagnosis and treatment were presented. Conclusions: distal tibioperoneal syndesmosis injuries are frequent ankle injury. Tomographic studies offer some advantages for determining how large the posterior malleolus fracture is. The arthroscopic approach offers multiple diagnostic and therapeutic advantages too.

Introduction: COVID-19 is a disease caused by SARS-CoV-2 virus and transmitted through respiratory track. So, dentists face a great risk working directly in the oral cavity. Objective: systematization of the theoretical references concerning the impact of COVID-19 in dental areas. Method: a systematic review on the subject was carried out at the Universidad Regional Autónoma de los Andes, from September to December 2022. Of a total of 36 articles reviewed, 23 were selected according to criteria, available in PUBMED and SciELO, published in English and Spanish by different authors, and associated to the COVID-19 transmission in dentistry. Results: the following topics were addressed: oral diseases caused by COVID-19, changes in dental areas due to the COVID-19 pandemic, and biosecurity measures used in the dental service for ensure patient safety receiving treatment. Final considerations: COVID-19 has had great repercussions in dentistry, which affects the oral and general health of patients and, in turn, leads to the use of strict biosecurity measures inside and outside the dental office, so, it is essential for dentists to become empowered of the theoretical references related to the subject and also be focused on detecting lesions that may constitute primary signs of a possible presence of SARS-CoV-2, in adopt responsible behaviors and to avoid any spread of disease.

Introduction: Staphylococcus epidermidis as an opportunistic pathogen and its ability to form biofilm has become an emergency situation. Objective: to identify biofilm-producing Staphylococcus epidermidis as a cause of urethritis in males. Study performed throughout 2019 in the Microbiología Lab of the Centro Provincial de Higiene, Epidemiología y Microbiología Lab in Guantánamo. Method: an observational, descriptive and cross-sectional study was carried out at the aforementioned lab, envolving a total of 48 male outpatients with a clinical diagnosis of urethritis certified by the family physician, attended in the Microbiology laboratory with their respective urethral discharge culture indication. The variables studied were as follow: coagulase, catalase and oxidase enzyme production test, growth of mannitol salt agar, novobiocin sensitivity, biofilm production and antimicrobial resistance. The sampling results were introduced in a database and processed with the software SPSS version 11.5. Results: biofilm-producing Staphylococcus epidermidis was identified as the cause of urethritis in the 48 male patients involved in the study. This microorganism showed cero or low resistance to ciprofloxacin, norfloxacin, amikacin, gentamicin, amoxicillin-sulbactam combination, cotrimoxazole and tetracycline. Conclusions: Staphylococcus epidermidis emerges as a common opportunistic pathogen in male patients with a clinical diagnosis of urethritis, with significant resistance to beta-lactam antibiotics not combined with beta-lactamase inhibitors.
