Quality and quality models to measure quality and assurance in public hospitals: Is it posible to regulate a construct?

Este artículo es una propuesta de reflexión sobre el concepto de calidad en salud en el contexto internacional y sus intentos por normar un constructo y definir un modelo, evidenciando que la calidad no se incorpora adecuadamente en los desarrollos legislativos. Los diversos enfoques y los estándares internacionales obligan a preguntarnos ¿Es posible definir, formalizar y generar un marco normativo único? La revisión bibliográfica tiene como objetivo caracterizar un constructo de calidad en salud y evidenciar los avances sanitarios en el mundo para dar cuenta de algunos modelos normativos orientadores de las políticas sanitarias en diversos países. Esta se complementa con más de 10 estudios de pre-inversión hospitalaria elaborados en Chile (entre el 2000 y el 2010). Se concluye que la calidad es un concepto multivariante, en constante evolución y movilidad. Su medición depende del área de trabajo y de quien mide. Asimismo que los análisis de los modelos de calidad reflejan que no hay consenso al respecto y, por lo mismo, hay que tener cuidado al abordar los marcos normativosThis article is a proposal for reflection on the concept of quality in health in the international context and its attempts to standardize a construct and define a model, evidencing that quality is not adequately incorporated into legislative developments. The different approaches and international standards force the following question: Is it possible to define, formalize and generate a single regulatory framework? The objective of the bibliographic review is to characterize a construct of quality in health and to demonstrate the health advances in the world to account for some normative models that guide health policies in different countries. This is complemented by more than 10 hospital pre-investment studies prepared in Chile (between 2000 and 2010). It is concluded that quality is a multivariate concept in constant evolution and mobility, that its measurement depends on the area of work and who measures it, and that the analyzes of the quality models reflect that there is no consensus in this regard and, therefore, care must be taken when approaching the regulatory framework

Impact of Probiotics on the Performance of Endurance Athletes: A Systematic Review

Background: Probiotic supplements contain different strains of living microorganisms that promote the health of the host. These dietary supplements are increasingly being used by athletes to improve different aspects such as athletic performance, upper respiratory tract infections (URTIs), the immune system, oxidative stress, gastrointestinal (GI) problems, etc. This study aimed to identify the current evidence on the management of probiotics in endurance athletes and their relationship with sports performance. Methods: A systematic review of the last five years was carried out in PubMed, Scopus, Web of science, Sportdiscus and Embase databases. Results: Nine articles met the quality criteria. Of these, three reported direct benefits on sports performance. The remaining six articles found improvements in the reduction of oxidative stress, increased immune response and decreased incidence of URTIs. There is little scientific evidence on the direct relationship between the administration of probiotics in endurance athletes and sports performance. Conclusions: Benefits were found that probiotics could indirectly influence sports performance by improving other parameters such as the immune system, response to URTIs and decreased oxidative stress, as well as the monitoring of scheduled workouts

Consumption of over-the-Counter Drugs: Prevalence and Type of Drugs

Recently, there has been an increase in the use of over-the-counter (OTC) drugs. The consumption of these medicines can be unsafe, as incorrect self-diagnosis or the ingestion of inappropriate doses can lead to side effects and the occurrence of adverse reactions and drug–drug interactions. A cross-sectional descriptive observational study was carried out, targeting the entire Spanish population by using an online questionnaire. The results showed that 78.9% of the subjects had previously taken or were currently taking OTC drugs. This consumption decreased as the age of the subjects increased, with a prevalence of 36.4% of subjects aged 71 taking OTC drugs. Analgesics were the most consumed OTC drugs (49.1%) especially in women, youngsters with non-formal educational qualifications, and individuals of a low–medium socioeconomic level residing in urban areas. Measures should be implemented to optimize the safe use of OTC drugs in order to avoid the occurrence of secondary events associated with the lack of knowledge related to their the usage

Perceived Stress and Increased Food Consumption during the ‘Third Wave’ of the COVID-19 Pandemic in Spain

The COVID-19 pandemic has impacted the mental health of people worldwide. An increase in perceived stress can lead to unhealthy behaviors such as increased food consumption. The aim of this study was to find the level of perceived stress and its relationship with increased food consumption during the "third wave" of the COVID-19 pandemic in Spain. This was a cross-sectional study that employed anonline self-reported frequency of consumption questionnaire and the Perceived Stress Scale-10. A total of 637 subjects participated and 83.6% of respondents had moderate or high stress-more prevalent in the female and young respondents. Moreover, 36.1% of respondents reported that they had increased the frequency of consumption of some foods, mainly nuts, snacks, and jellybeans, along with coffee, tea, cocoa, and soft drinks. Eating between meals was more pronounced in those with high stress (65.1%) than in those with moderate stress (40.4%) and low stress (20.2%). Furthermore, the respondents with high stress reported greater weight gain. Thus, the results show that the level of perceived stress during the 'third wave' of this pandemic increased food consumption

Regular Exercise Improved Fatigue and Musculoskeletal Pain in Young Adult Psoriatic Patients without Psoriatic Arthritis

Fatigue and musculoskeletal pain are also frequent in patients with psoriasis (PsO) without arthritis (PsA). The current study aimed to assess the impact of an intervention program based on aerobic training to reduce fatigue and musculoskeletal pain in patients with PsO without PsA. A total of 118 male patients with PsO volunteered in the current interventional study and were randomly allocated to the experimental (n = 59) or control group (n = 59). The intervention consisted of a 16-week aerobic training program on a treadmill, three sessions per week, consisting of a warm-up, 35-50 min treadmill exercise (increasing 5 min/4 weeks) at a work intensity of 50-65% of peak heart-rate (increasing 5%/4 weeks), and cooling-down. The functional assessment of chronic illness therapy fatigue scale (FACIT-Fatigue), health assessment questionnaire disability index (HAQ-DI), and visual analog scale (VAS) were compared pre and post intervention. Nutritional intake, maximal aerobic power, lipid profile, serum markers of muscle damage, and body composition were also assessed. When compared to baseline, FACIT-Fatigue, HAQ-DI, and VAS scores were significantly improved without increasing markers of muscle damage. Fat mass percentage, lipid profile, and maximal oxygen consumption were also improved. In conclusion, a 16-week aerobic training program at moderate intensity was safe, well tolerated, and effective in psoriatic patients without PsA. Long-term follow-up studies are required to examine whether these promising results may improve clinical outcomes

Endothelial dysfunction is an early indicator of sepsis and neutrophil degranulation of septic shock in surgical patients

Producción CientíficaBackground: Stratification of the severity of infection is currently based on the Sequential Organ Failure Assessment (SOFA) score, which is difficult to calculate outside the ICU. Biomarkers could help to stratify the severity of infection in surgical patients. Methods: Levels of ten biomarkers indicating endothelial dysfunction, 22 indicating emergency granulopoiesis, and six denoting neutrophil degranulation were compared in three groups of patients in the first 12 h after diagnosis at three Spanish hospitals. Results: There were 100 patients with infection, 95 with sepsis and 57 with septic shock. Seven biomarkers indicating endothelial dysfunction (mid-regional proadrenomedullin (MR-ProADM), syndecan 1, thrombomodulin, angiopoietin 2, endothelial cell-specific molecule 1, vascular cell adhesion molecule 1 and E-selectin) had stronger associations with sepsis than infection alone. MR-ProADM had the highest odds ratio (OR) in multivariable analysis (OR 11·53, 95 per cent c.i. 4·15 to 32·08; P = 0·006) and the best area under the curve (AUC) for detecting sepsis (0·86, 95 per cent c.i. 0·80 to 0·91; P < 0·001). In a comparison of sepsis with septic shock, two biomarkers of neutrophil degranulation, proteinase 3 (OR 8·09, 1·34 to 48·91; P = 0·028) and lipocalin 2 (OR 6·62, 2·47 to 17·77; P = 0·002), had the strongest association with septic shock, but lipocalin 2 exhibited the highest AUC (0·81, 0·73 to 0·90; P < 0·001). Conclusion: MR-ProADM and lipocalin 2 could be alternatives to the SOFA score in the detection of sepsis and septic shock respectively in surgical patients with infection.Instituto de Salud Carlos III (grants PI15/01959, PI15/01451 and PI16/01156

Consenso colombiano de enfermedad inflamatoria intestinal

La Enfermedad inflamatoria intestinal (EEI) es un término con el que se conocen varias entidades, las dos más importantes: la colitis ulcerativa idiopática (CUI) y la enfermedad de Crohn (EC), cuyo origen es multifactorial y se caracterizan por un fenómeno inflamatorio, crónico, recurrente, con diferentes grados de severidad del tubo digestivo; pero, además con afectación potencial de otros órganos. En la última década ha habido un renovado interés en dichas entidades, debido a un auge en medicamentos novedosos; a pesar de lo cual estas siguen siendo incurables. Lo anterior asociado a una incidencia creciente de dicha patología en nuestro país nos obliga tanto científica como moralmente a convocar a un panel de expertos para elaborar unos lineamientos básicos en el enfoque y manejo de la EEI. OBJETIVOS 1. Desarrollar un consenso adaptado a nuestro medio, basado en documentación científica de la mejor calidad disponible para el enfoque diagnóstico y el manejo médico y quirúrgico. 2. Publicar y difundir dichos lineamentos tanto a la comunidad científica como al público en general a través de foros especializados, y medios de comunicación de alta penetración. 3. Elaborar y divulgar el consenso en forma de suplemento de la Revista Colombiana de Gastroenterología, el 8 de diciembre de 2011, en medio del congreso de ACADI (Asociación Colombiana de Asociaciones del Aparato Digestivo); es el mejor homenaje que el panel multidisciplinario de expertos le puede rendir a dicho evento; pero más importante aún es el reconocimiento que se le hace a los pacientes que padecen de dicha patología en nuestro país, quienes en últimas son nuestra razón de ser. METODOLOGÍA 1. Se invitaron médicos especialistas (Clínicos y quirúrgicos), líderes de opinión e industria farmacéutica nacional, cuyo área de interés y de trabajo es la EEI. 2. Se separó y manejó independientemente desde el principio la CUI de la EC. A su vez, se dividió cada entidad por módulos, con base en el método de panel de Delphi, se nombró un coordinador por cada uno de ellos, el cual se encargó de analizar junto con su equipo la literatura, para extraer el nivel de evidencia clínica y así emitir unos conceptos preliminares. Posteriormente, todo el panel de expertos se reunió en varias jornadas y conjuntamente se revisó nuevamente la evidencia clínica y conclusiones de los diferentes módulos homogenizándolas y de una manera concertada se formularon las recomendaciones definitivas.Q4https://orcid.org/0000-0002-9219-4548Revista Nacional - Indexad

First Latin American clinical practice guidelines for the treatment of systemic lupus erythematosus: Latin American Group for the Study of Lupus (GLADEL, Grupo Latino Americano de Estudio del Lupus)-Pan-American League of Associations of Rheumatology (PANLAR)

Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an 'overarching' treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings.Fil: Pons Estel, Bernardo A..
