Management Models in SMEs, Strategic Tool in Business Management

The business sector constitutes an engine for the Ecuadorian economy through the generation of employment and redistribution of wealth. Therefore, given the current economic dynamics of high competition, globalization of markets, and use of information and communication technologies, business managers need to use different tools such as management models to achieve acceptable levels of utility, profitability, customer satisfaction and permanence in the consumer market. This research involved an analysis of the impact on corporate management of applying different management models of Small and Medium Enterprises (SMEs) in the city of Riobamba, province of Chimborazo (Ecuador). The study was descriptive, cross-sectional, exploratory and non-experimental and it was conducted in the first half of 2019. Data were collected through field investigation and the application of a structured survey with a sample composed of 136 managers, owners and administrators, from a population of 440 entrepreneurs. The results showed that 93% of entrepreneurs knew about the existence of management models, and 41% recorded that total quality is the most applied model followed by continuous improvement (18%) and re-engineering (13%). We conclude that entrepreneurs consider management models to be crucial in the management of their company. Keywords: management model, business management, strategies, competitiveness, SMEs.

Specific bioelectrical impedance vector analysis (BIVA) is more accurate than classic BIVA to detect changes in body composition and in nutritional status in institutionalised elderly with dementia

A new analytical variation of bioelectrical impedance vector analysis (BIVA), called specific BIVA, has shown to be more accurate in detecting changes in fat mass than classic BIVA.To compare classic and specific BIVA in order to identify which is more strongly associated with psycho-functional and nutritional indicators in a group of institutionalised elderly patients with dementia.Cross-sectional study. Fifty-four patients (34 women, 20 men) with dementia in moderately severe to very severe stages and aged 60–95years underwent geriatric nutritional assessment, including body mass index calculations, the Mini Nutritional Assessment, the Geriatric Nutritional Risk Index, and whole body composition analysis.With specific BIVA (unlike with classic BIVA), significant differences were found between women with moderately severe and very severe dementia. In the BIVA conducted for body mass index, the confidence ellipses produced with the classic BIVA approach were highly overlapping; but with specific BIVA, significant differences were observed between the women in different nutritional categories (malnutrition, risk of malnutrition, normal weight and obesity). On the other hand, both approaches distinguished malnourished women from those who were at risk of malnutrition, according to the Mini Nutritional Assessment; and men with a moderate-high risk of malnutrition from men with no risk, on the basis of the Geriatric Nutritional Risk Index.Overall, the findings of the present study suggest that specific BIVA is more effective than classic BIVA in identifying bioelectrical changes associated with psycho-functional and nutritional indicators in institutionalised elderly with dementia

Presencia de malnutrición y riesgo de malnutrición en ancianos institucionalizados con demencia en función del tipo y estadío evolutivo

Producción CientíficaDeterminar si existen diferencias en el estado nutricional de los pacientes con demencia en función del tipo y la severidad de la misma. Método: Mediante un estudio transversal se realizó una valoración del estado nutricional (valoración antropométrica, Mini Nutricional Assessment, protocolo de Chang) en 83 ancianos institucionalizados con diagnóstico de demencia en estadíos evolutivos 5, 6 y 7 de las escalas GDS (Global Deterioration Scale) y FAST (Functional Assessment Stating). Los resultados se analizaron mediante los tests Chi-cuadrado, ANOVA o Kruskal-Wallis, contrastes a posteriori de Scheffé y test de tendencia lineal. La significación se alcanzó con p < 0,05. Resultados: La edad media de los residentes fue de 81,22 años. El IMC reveló que el 21% de la muestra presentaba riesgo de malnutrición y el 14,5% malnutrición por defecto. En cambio, el MNA clasificó al 56,6% de los residentes en situación de riesgo de malnutrición y al 41% con malnutrición. Según el método de Chang el porcentaje de pacientes malnutridos ascendió al 75,9%. Ninguna de estas variables mostró asociación con el tipo de demencia. Se observó una asociación significativa entre el estadío evolutivo de la demencia y el IMC (p = 0,004), MNA (p = 0,002 y p = 0,006 para la puntuación y la categoría, respectivamente), circunferencia muscular del brazo (p = 0,043) y circunferencia de la pantorrilla (p = 0,043); aunque no para el porcentaje de masa grasa ni para el diagnóstico nutricional establecido por el método de Chang (grado y tipo de MN). El test de tendencia lineal confirmó que tanto las puntuaciones del MNA y del IMC, como los valores de la circunferencia muscular del brazo y de la circunferencia de la pantorrilla fueron menores en los estadíos de demencia más severos. Conclusión: Independientemente del tipo de demencia, la presencia de malnutrición en ancianos institucionalizados aumenta conforme lo hace el estadío evolutivo de la misma

Bioimpedance vector analysis and conventional bioimpedance to assess body composition in older adults with dementia

Producción CientíficaAlthough dementia and nutritional status have been shown to be strongly associated, differences in body composition (BC) among older people with dementia have not yet been firmly established. The aim of this study was to assess BC through conventional and vector bioimpedance analysis (BIA and BIVA, respectively) in a sample of institutionalized older men with and without dementia, in order to detect dementia-related BC changes.Forty-one institutionalized men ages ≥65 y (23 without dementia [CG] and 18 with dementia [DG]) were measured with BIA and interpreted with BIVA and predictive equations.Age (74.4 and 75.7 y) and body mass index (22.5 and 23.6 kg/m 2 ) were similar for DG and CG, respectively. Resistance and ratio of resistance to height did not differ significantly between the two groups. Reactance and ratio of reactance to height were 21.2% and 20.4% lower in DG than in CG. Phase angle was significantly lower in DG (mean = 4.0; 95% confidence interval [CI], 3.6°–4.3°) than in CG (mean = 4.7; 95% CI, 4.3°–5.1°). Mean fat mass index (6 and 7 kg/m 2 ), and mean fat-free mass index (16.4 and 16.6 kg/m 2 ) were similar in both groups. BIVA showed a significant downward migration of the ellipse in DG with respect to CG (T 2 = 15.1; P < 0.01).Conventional BIA showed no significant differences in BC between DG and CG, although reactance and ratio of reactance to height were about 21% lower in DG. Nevertheless, a body cell mass depletion and an increase in the ratio of extracellular to intracellular water were identified in DG using BIVA. BIVA reflects dementia-related changes in BC better than BI

The impact of supportive nursing care on the needs of men with prostate cancer: a study across seven European countries

Background: prostate cancer is for many men a chronic disease with a long life expectancy after treatment. The impact of prostate cancer therapy on men has been well defined, however, explanation of the consequences of cancer treatment has not been modelled against the wider variables of long-term health-care provision. The aim of this study was to explore the parameters of unmet supportive care needs in men with prostate cancer in relation to the experience of nursing care. Methods: a survey was conducted among a volunteer sample of 1001 men with prostate cancer living in seven European countries. Results: at the time of the survey, 81% of the men had some unmet supportive care needs including psychological, sexual and health system and information needs. Logistic regression indicated that lack of post-treatment nursing care significantly predicted unmet need. Critically, men's contact with nurses and/or receipt of advice and support from nurses, for several different aspects of nursing care significantly had an impact on men's outcomes. Conclusion: Unmet need is related not only to disease and treatment factors but is also associated with the supportive care men received. Imperative to improving men's treatment outcomes is to also consider the access to nursing and the components of supportive care provided, especially after therapy

Synthesis and in vivo evaluation of non-hepatotoxic acetaminophen analogs

A series of acetaminophen (APAP) analogs, 2-(1,1-dioxido-3-oxo-1,2-benzisothiazol-2(3H)-yl)-N-(4-hydroxyphenyl)alkanecarboxamides, bearing a heterocyclic moiety linked to the p-acylaminophenol fragment, were prepared in a general project to develop APAP analogs with modulated pharmacokinetic profiles. Unexpectedly, the products described maintained the in vivo analgesic profile, while the characteristic hepatotoxicity of APAP was consistently reduced. One of the products, 5a, was studied in vivo in comparison with APAP. Compound 5a displayed an analgesic efficacy comparable to that of APAP. A relatively high acute oral dose of 5a (6 mmol/kg) produced no measurable toxicity, whereas the equimolar dose of APAP increased transaminase activity, depleted hepatic and renal glutathione, and resulted in mortality. In human hepatocytes (HEPG-2) and in human primary cultures of normal liver cells, APAP, but not 5a, was associated with apoptotic cell death, Fas-ligand up-regulation, and CAR (constitutive androstane receptor) activation, contributing to a favorable safety profile of 5a as an orally delivered analgesic.MDA972-03-C-010 (Defense Advanced Research Programs Agency-DARPA)Neurobiotechnology Program of Louisian
