Nutritional factors and pressure injury risk in hospitalised patients post-stroke.

OBJECTIVE: This study aimed to analyse the nutritional factors and pressure injury (PI) risk in hospitalised patients post-stroke. METHOD: The research employed a descriptive observational method in which patients ≥18 years of age were followed for six days. Nutritional evaluation was based on anthropometric and dietary factors. The nutritional risk was assessed via anthropometric measurements, Braden nutrition subscale and daily dietary intake. PI risk was evaluated through the Braden Scale. The Wilcoxon test, paired t-test, and Kruskal-Wallis test were applied and corrected with Bonferroni correction or analysis of variance, followed by the post hoc Tukey test. RESULTS: During their hospital stays, the participating 59 patients had an increase in sensory perception (p=0.02) and nutrition (p=0.005) scores. It was observed that patients at high risk of PI did not meet daily nutritional recommendations for calories, proteins, carbohydrates, lipids and micronutrients (zinc, selenium and copper) compared with patients at low-to-moderate risk. Weight (p<0.001), body mass index (p<0.001), calf (p=0.01) and arm (p=0.04) circumferences, and subscapular (p=0.003) and triceps (p<0.001) skinfolds decreased during the six days of hospitalisation. CONCLUSION: From the findings of this study, it was concluded that nutritional factors, such as unmet recommended daily nutritional requirements of macronutrients and micronutrients, and nutritional status are associated with a higher risk of developing a PI.

Comportamento da variabilidade glicêmica em pacientes hospitalizados com Diabetes Mellitus 2 / Behavior of glycemic variability in hospitalized type 2 Diabetes Mellitus patients / Comportamiento de la variable glucémica en pacientes Hospitalizados con Diabetes Mellitus 2

Introdução: A hiperglicemia pode estar presente em até 38% dos pacientes hospitalizados.O controle glicêmico está associado a melhores desfechos clínicos. Objetivo: avaliar o comportamento da variabilidade glicêmica em pacientes hospitalizados com Diabetes Mellitus 2. Metodologia: Estudo transversal, composto por pacientes hospi-talizados com e sem diabetes, adultos e idosos, de ambos os gêneros, em terapia nutricional enteral. As glicemias foram medidas por testes de glicemia capilar e classificadas como normoglicemia, hiperglicemia e variabilidade glicêmica, avaliados a partir do desvio-padrão glicêmico e coeficiente de variação glicêmico. Foram avaliados dados bioquímicos como Proteína C-reativa. A análise de variância de duas vias (ANOVA) foi utilizada para comparar os grupos, além da correlação de Spearman. Resultados: Participaram 85 indivíduos, com diabetes mellitus 2 (20%; n= 17), e sem diabetes mellitus (80%; n = 68), sendo 34% (n = 29) adultos e 66% (n=56) idosos. Adultos e idosos com diabetes mellitus apresentaram hiperglicemia em relação aos pacientes não diabéticos (p<0,01), valores supe-riores de desvio-padrão glicêmico (p<0,01) e coeficiente de variação glicêmica em relação aos pacientes sem dia-betes (p= 0,03), no entanto, não foram classificados com variabilidade glicêmica. Os valores da Proteína C-reativa foram correlacionados com o desvio-padrão glicêmico (R= 0,29; p= 0,0065), no entanto, a quantidade de carboi-dratos infundida na dieta enteral não se correlacionou estatisticamente com as glicemias nem com a variabilidade glicêmica dos pacientes (p>0,05). Conclusão: pacientes hospitalizados com ou sem diabetes mellitus 2 não apre-sentaram variabilidade glicêmica, demonstrando um controle glicêmico na hospitalização. (AU)

Introduction: Hyperglycemia may be present in up to 38% of hospitalized patients. Glycemic control is associated with better clinical outcomes. Objective: assess the behavior of glycemic variability in hospitalized patients with Diabetes Mellitus 2. Methodology: Cross-sectional study composed of hospitalized patients with and without diabetes, adults and elderly, of both genders, undergoing enteral nutritional therapy. Blood glucose was measured by capillary blood glucose tests and classified as normoglycemia, hyperglycemia, and glycemic variability, assessed from the glycemic standard deviation and glycemic variation coefficient. Biochemical data such as C-reactive protein were assessed. Two-way analysis of variance (ANOVA) was used to compare the groups, in addition to Spearman's correlation. Results: Eighty-five individuals with diabetes mellitus 2 (20%; n=17) and without diabetes mellitus (80%; n=68) participated in the study; 34% (n=29) were adults, and 66% (n=56) were elderly. Adults and elderly people with diabetes mellitus presented hyperglycemia concerning non-diabetic patients (p<0.01), higher values of glycemic standard deviation (p<0.01), and glycemic variation coefficient concerning patients without diabetes (p= 0.03); however, they were not classified with glycemic variability. The C-reactive protein values were correlated with the glycemic standard deviation (R= 0.29; p= 0.0065); however, the amount of carbohydrates infused in the enteral diet was not statistically correlated with glycemia or with the glycemic variability of patients (p>0.05). Conclusion: hospitalized patients with or without diabetes mellitus 2 did not show glycemic variability, demonstrating glycemic control during hospitalization. (AU)

Introducción: La hiperglucemia puede estar presente hasta en un 38% de los pacientes hospitalizados. El con-trol glucémico se asocia con mejores resultados clínicos. Objetivo: evaluar el comportamiento de la variación glucémica en pacientes con Diabetes Mellitus 2. Metodología: Estudio transversal, compuesto por pacientes hos-pitalizados con y sin diabetes, adultos y ancianos, con terapia nutricional enteral. Las glucemias fueron medidas por exámenes de glucemia capilar y clasificadas como normo glucemia, hiperglucemia y variación glucémica, evaluados a partir de la desviación estándar y coeficiente de variación glucémico. Fueron evaluados datos bioquí-micos como Proteína C-reactiva. El análisis de la variación de las dos vías (ANOVA) fue utilizada para comparar los grupos, junto a la correlación de Spearman. Resultados: Participaron 85 individuos, con diabetes mellitus 2 (20%; n+17), y sin diabetes mellitus (80%; n = 68). Adultos 34% (n=29) y ancianos 66% (n=56). Pacientes con diabetes mellitus presentaron hiperglucemia en relación a los pacientes nodiabéticos (p< 0,01), valores superiores de desviación estándar glucémico (p< 0,01) y coeficiente de variación glucémica en relación a los pacientes sin dia-betes (p= 0,03), sin embargo, no fueron clasificados con variación glucémica. Los valores de la Proteína C-reactiva fueron correlacionados con la desviación estándar glucémica (R = 0,29; P= 0,0065), la cantidad de carbohidratos administrada, no se correlacionó estadísticamente con las glucemias ni con la variación glucémica de los pacientes (p>0,05). Conclusión: pacientes hospitalizados con o sin diabetes mellitus 2 no presentaron variación glucémica, demostrando control glucémico en la hospitalización. (AU)

Dysphagia, Immobility, and Diet Acceptance: Main Factors Associated with Increased Risk of Pressure Injury in Patients Hospitalized after Stroke.

OBJECTIVE: To determine the predisposing factors for PI in patients hospitalized after stroke. METHODS: This 7-day longitudinal study followed up with patients hospitalized after stroke. Assessments included mobility, nutrition, and the presence of dysphagia and anemia. The nutrition evaluation was based on anthropometric, biochemical, and dietary determinants. Pressure injury (PI) risk was assessed via the Braden Scale. Mann-Whitney and Kruskal-Wallis tests were applied. RESULTS: Patients who were bedridden showed a greater risk of PI development upon admission (P = .004) and 7 days later (P < .001) compared with patients who could ambulate. Patients who were not dysphagic presented a lower risk of PI development in relation to patients who were dysphagic on admission (P = .047) and 7 days later (P < .001). On admission, patients with good and average diet acceptance had a lower PI risk (P = .002; P = .034) compared with those with a low acceptance. Body mass index was lower in patients at a high risk of developing PI compared with those at moderate risk (P = .02). Hemoglobin and hematocrit were statistically lower among patients who were at high risk of PI compared with patients who were low risk. CONCLUSIONS: Predisposing factors such as immobility, dysphagia, low diet acceptance, nutrition risk, and anemia are associated with a greater risk of PI development.
