Introduction: infections associated with health care constitute a serious public health problem worldwide due to their frequency and high mortality. Objective: to identify the level of knowledge, attitudes and practices to control in-hospital infections of healthcare personnel. Method: a descriptive cross-sectional study was carried out at the Santiago de Jinotepe Hospital in Carazo, Nicaragua, January-June 2017. The universe consisted of 345 hospital workers, including inmates of the medical career and the intentional sample or for convenience, from 53 suppliers. The variables used: occupational classification, level of knowledge about the definition of infections associated with health care (HCAI) and the effect of washing hands with water and soap to remove Gram-negative bacilli, as well as the evaluation of practices and attitudes related to the prevention of the IAAS. Results: cognitive deficit was found in the infections associated with health care and in the correct attitudes and practices in the care personnel for its prevention. Conclusions: there is a lack of knowledge about the infections associated with health care, as well as the exercise of correct attitudes and practices aimed at their prevention, for this purpose, a training program should be designed at this level of care to try to reduce HCAIs.

Introduction: in Cuba one of the social demands is the study of skin cancer in the elderly population.Objective: to characterize clinical-epidemiological aspects in patients with probable diagnosis of PC admitted in the homes of elderly "CaridadJaca" and "San José" of the city of Guantánamo during the year 2017.Method: an observational, prospective and cross-sectional study was conducted with all the elderly (n = 256) and in those with probable skin cancer (n = 15), age was specified; sex; place of birth, where he lived; personal pathological history; cutaneous type photo; characteristics of the lesion; clinical and dermatoscopic diagnosis.Results: skin cancer was diagnosed in 5.9% of the elderly. It was more common in men (53.4%), with 70 to 79 years (53.4%), born or who lived in urban areas and photo cutaneous type III (40.0%). 100.0% was exposed to sunlight, 86.7% without means of photo protection. The cancer was located more in the face (66.7%), had an area less than one centimeter (46.6%), between 3 and 4 years of evolution (60.0%), it was a single lesion (86, 7%) and basal cell carcinoma (46.6%). In 80.0% of the cases, a clinical-dermatoscopic diagnostic correlation was observed.Conclusions: the frequency of skin cancer in the elderly was low. However, more attention must be paid to ensure the early diagnosis of this disease.

Introduction: Stomatology faculties have a predominant role in environmental management for their general performance, innovation and sustainable development. Objective: to diagnose the aspects and associated environmental impacts in the Faculty of Stomatology of Havana in the period 2015-2017. Method: qualitative research. Theoretical methods of analysis and synthesis, deduction and induction were used and as empirical methods the observation and system approach; bibliographic and documentary review was made on subjects related to the object of study. In addition, a survey and an interview were applied. The population and sample constituted 90 workers. Results: through the diagnosis, environmental aspects and impacts were identified and evaluated, which are not significant due to the possibility of their occurrence, given the general evaluation. The environmental conditions of the faculty did not constitute a high risk for the health of the personnel and their community. The diagnosis allowed to know the position of the organization with respect to its environment and internally to manage the environment and health and safety at work. Conclusions: a diagnosis of environmental aspects and impacts in the Faculty of Dentistry can be a useful tool for the identification of problems that affect the environment, health and safety of work, which could allow the design of Environmental Management Systems, what is a requirement of the Cuban Public Health.

Introduction: the prostate cancer is the first cause of death for cancer in the Cuban men and it affects the sexual quality of life. Objective: to characterize the results of the use of the sildenafil for the management of the erectile sexual dysfunction in patient with prostate cancer tried with hormones or radiotherapy. Method: was an observational, ambispective and traverse study, in the Service of Urology of the Hospital Dr. Agostinho Neto of Guantánamo during the period 2014-2018 that it was approved by the committee of medical ethics. The study universe conformed to for 70 patients with diagnostic of prostate cancer, treaties with hormones and/or radiotherapy, and that they presented erectile dysfunction. In each patient was studied the age, treatment that was applied for the cancer, time of appearance of the dysfunction after this, and the answer of the erectile function of the penis to the sildenafil use. Results: The 37.2% of the patients had between 70 and 79 years of age and 79.1% were talked with hormones. The biggest proportion presented erectile dysfunction 1 to 2 years after the treatment (48.8%). The 81.4% responded appropriately to the treatment with sildenafil, what was independent of the treatment of the cancer with hormones or radiotherapy. Conclusion: The patients with prostate cancer tried with hormones and/or radiotherapy benefitted with the use of the sildenafil.

Introduction: the social construction of gender with the influence of the androcentric culture is a reality of the world and Cuban society. In young people it is evident the presence of sexist stereotypes that are assumed as natural by family education and the development of relationships established in the course of their lives. Objective: to identify sexist stereotypes in third-year Stomatology students of the Guantánamo University of Medical Sciences. Method: a descriptive, transversal study was carried out. The population was composed of 30 students from the third year of that career. Results: it was shown that sexist stereotypes exist in these students, which contributes to the establishment of power relations. Conclusions: the existence of sexist stereotypes is evident in the gender roles configured from socializing elements such as the family, educational institutions and the media.

Introduction: HIV/AIDS is one of the diseases that has had the greatest social impact and affects millions of people. Objective: to identify the susceptibility and self-efficacy of the health professionals of the Faculty of Stomatology of the Benemérita Autonomous University of Puebla (FEBUAP) against the HIV / AIDS virus. Method: it was a descriptive observational study. 250 students and 50 FEBUAP teachers were included, with prior voluntary acceptance and signed informed consent, selected by means of a convenience sample. The HIV/AIDS-65 scale was applied, an instrument with proven validity and reliability for the evaluation of the subscales of the instrument (Cronbach alpha 0.79), proposed by Paniagua in 1998 and adapted to Spanish by Bermúdez, Buela-Casal & Uribe in 2005. Results: with respect to self-efficacy, the students demonstrated superiority. In the susceptibility, the belief of the possibility of contracting the virus was higher in teachers (64% vs. 48%). The belief that only homosexuals should worry about contagion was higher in teachers (92%). We found a higher self-efficacy in students and a better susceptibility in teachers. Conclusions: it is necessary to strengthen strategies that reinforce concepts and behaviors against HIV / AIDS.

Introduction: atrial fibrillation is the most frequent cardiac arrhythmia that is treated in clinical practice and produces 33% of hospitalizations associated with arrhythmias. Objective: to identify risk factors for cerebral thromboembolic complications in patients with permanent non-valvular atrial fibrillation and oral anticoagulant treatment between 2015 and 2018. Method: a case-control study was conducted in the General Teaching Hospital "Dr Agostinho Neto" in the period October between 2015 and April 2018. The universe consisted of 213 patients, 71 cases with permanent atrial fibrillation who suffered cerebral thromboembolic complications under treatment with warfarin and 142 controls with permanent atrial fibrillation, with the same, but without the aforementioned complications. Two controls were selected for each case (2: 1) to increase the statistical power of the study. We analyzed sociodemographic, clinical, echocardiographic variables, lability of the INR (international normalized index) and therapeutic adhesions. The analysis of the data was presented in double entry data tables. Chi square, Confidence Intervals and Odds ratio were estimated. Results: the age group of 75 or more years, the male sex, arterial hypertension, the presence of plaques of atheroma in the aorta and carotids, diabetes mellitus, suboptimal INR, poor therapeutic adherence were significant. Conclusions: the age group of 75 years or older, male sex, smoking, high blood pressure, diabetes mellitus, atheromatous plaques in the aorta and carotids, suboptimal INR and poor therapeutic adherence constitute significant risk factors for the appearance of cerebral thromboembolic complications.

The study of a family of the health area of the Community Polyclinic of Palma Soriano was presented with the aim of socializing the experience of the early cognitive stimulation of an older adult with cognitive deterioration through family support. The study concluded in 2015, in Palma Soriano. The non-experimental research design was used, instrumental case study from the qualitative methodology. The study included a family, was based on the work of the focus group and assisted in standardized techniques. It was concluded that the family support provided to the patient with cognitive impairment positively impacts their physical condition, psychological well-being and social relationships. Likewise, family support was recognized as a necessary, emotionally important and coherent path with the Cuban socio-demographic situation, which enables early cognitive stimulation of the elderly with cognitive impairment.
