INTRODUCTION With a global adult prevalence of 24%, nonalcoholic fatty liver disease is a global health problem that parallels the worldwide increase of obesity. Its frequency, clinical characteristics and related diseases in Cuba remain unknown. OBJECTIVE Describe the clinical characteristics, comorbidities and personal habits of patients with non-alcoholic fatty liver disease who are being treated in secondary and tertiary health facilities in seven Cuban provinces. METHODS A cross-sectional, multicenter study was carried out in 6601 adults seen at gastroenterology outpatient clinics of nine hospitals in seven Cuban provinces from September 2018 through May 2019. Non-alcoholic fatty liver disease was diagnosed by abdominal ultrasound. The study included 1070 patients who met the diagnostic and study criteria and agreed to participate. Their personal habits and anthropometric and clinical characteristics, comorbidities and other aspects of their medical histories were recorded. RESULTS Of the 1070 participants, 60.7% (649) were women. Participants' average age was 54.5 years and average body mass index was 30.5 kg/m2. A total of 397 (37.1%) were overweight and 574 (53.6%) were obese, 945 (88.3%) led a sedentary lifestyle, 564 (52.7%) had high blood pressure, 406 (37.9%) had lipid disorders and 301 (28.1%) were diabetic. While 484 (45.2%) of patients were asymptomatic, the most frequent clinical signs and symptoms were fatigue (262; 24.5%), dyspepsia (209; 19.5%), abdominal pain (306; 28.5%) and hepatomegaly (189; 17.7%). Liver cirrhosis was present in 37 (3.5%) patients at the time of diagnosis. Family history of type 2 diabetes mellitus and obesity were identified in 391 (36.5%) and 279 (26.1%) of participants, respectively. CONCLUSIONS Prevalence of non-alcoholic fatty liver disease in these Cuban patients coincides with that reported in the Caribbean region, which has high levels of obesity, overweight and sedentary lifestyles. Most were asymptomatic, female or had metabolism-related comorbidities such as high blood pressure, type 2 diabetes mellitus and dyslipidemia. [ABSTRACT FROM AUTHOR]

Jacinto Torras de la Luz es uno de los exponentes del Pensamiento Económico Cubano menos estudiado. En los trabajos dedicados al estudio de su obra, uno de los temas más abordado ha sido el de las relaciones económicas externas. Ello evidencia el reconocimiento de aquellos que han estudiado su pensamiento, a la utilidad de sus análisis sobre el asunto. [ABSTRACT FROM AUTHOR]

El artículo discurre sobre el primer registro de Spodoptera exigua, un especie de polilla, en Cuba. Los autores comentan sobre su interacción con cultivos protegidos y describen su introducción en esta región del mundo en 1875.

The work was done en the cultivation houses of ¨La Quinta¨ of the company of several cultivations of Sancti Spíritus in the months of March to July of 2011. In two house of cultivation of tomato 540 m2. One week before the floor to reason of 0.5 kg/m2 (270kg) blended with 2.16 kg of Trichoderma harzianum A-34 solid with a concentration of 2.5x 109 conidios for g(4g/m2) of floor). After the crop was incorporate to the floor a treatment of on experimental formulated of Trichoderma (Trichobiol 34 PH) with the fatirriego system to reason of 5x1012 conidios/ha. With the objective of evaluate the levels of affectation for nematodes. The use of Trichoderma solid and blended with worm humus and the addition of a preparation of commercial powdered Trichobiol (34 PH) reduce the contamination degree of nematodes 2, to degree 1 in a period of 13 days in the treated house and they statued at that level until the crop.

This work summarizes the results of the national project Comprehensive quality improvement in the diagnosis and treatment of patients with cancer and other diseases, incorporating and strengthening radioguided surgery techniques. This project had the objective of raising the quality in the diagnosis and treatment of patients with cancer and other diseases, by introducing, expanding and optimizing the clinical use of radioguided surgery in Cuba. First, the technique was started in the “Hermanos Ameijeiras” hospitals, the National Institute of Oncology and Radiobiology and the Center for Medical Surgical Research, with the protocolized follow-up and the analysis of the clinical impact, the national guidelines were drawn up and the accreditation proceeded. of courses and workshops for the training of human resources, guaranteeing sustainability and extension to other hospitals. As main results, in February 2020, 570 breasts had been operated with this technique, with a rate between 65-70 % of unnecessary axillary emptyings avoided, noting the improvement in staging and diagnostic precision the decrease in surgical time per patient in 30 %, lower costs of surgery, fewer associated complications and shorter hospital stays due to minimally invasive surgery and a significant improvement in the quality of life of patients.

A study on the need and importance of the effective application of knowledge management as a factor generating competitive edge in the organizations and demanding an enhanced organizational culture is presented. The first steps to achieve this at Ediciones Futuro Publishing house of the University of Computing Sciences are listed. According to the contributions of several authors, experiences and case studies supporting this research, the types of knowledge existing in the organization are characterized, the intellectual capital is described and activities are proposed to socialize knowledge. This work allows an approach to the work of this young group and to the new proposals to achieve results and top quality products. The existing knowledge requires consolidation and updating according to the opportunities offered by the information and communication technologies and the increasing convergence of publications and their versions in electronic format. The group must continue its preparation to face bigger challenges. As a conclusion they showed initiatives promoting the socialization of knowledge and allowing the optimization of its management.
