- Handgrip dynamometry and patient-generated subjective global assessment in patients with nonresectable lung cancerPublication . Barata, Ana T.; Santos, Carla; Cravo, Marília; Vinhas, Maria do Céu; Morais, Catarina; Carolino, Elisabete; Mendes, Lino; Roldão Vieira, Jorge; Fonseca, JorgeIntroduction - Undernutrition is frequently associated with advanced lung cancer. Accurate nutritional assessment tools are important to provide the proper nutritional therapy. Handgrip dynamometry has already been used in these patients, and the findings suggest that it is a good indicator of nutritional status. Aims - The aim of this study was to evaluate the association between nutritional status and handgrip strength (HGS) in patients with nonresectable lung cancer. Methods - Cross-sectional study involving thirty-seven subjects with nonresectable lung cancer. Nutritional status was obtained using Patient Generated Subjective Global Assessment (PG-SGA), and muscle function was evaluated by HGS using a Jamar® handgrip dynamometer on the nondominant hand. The results of both methods were compared and correlated. Results - According to PG-SGA, 73% (n = 27) of the patients were moderately undernourished, and 8% (n = 3) were severely undernourished. In total, 81% (n = 30) were undernourished. HGS was below the 50th percentile in 57% of the patients (n = 21). We found a significant association between nutritional status according to PG-SGA and HGS (P = 0.026, CI = 95%). Conclusions - Handgrip dynamometry can be a useful tool to evaluate the functional and nutritional status. It can be included in lung cancer patients evaluation, along with other nutritional assessment tools.
- Ingesta nutricional en pacientes afectados de esclerosis lateral amiotrófica en una consulta ambulatoria de nutrición artificial en PortugalPublication . Carrera-Juliá, Sandra; Moreira, Ana Catarina; Santos, Carla Adriana; Fonseca, Jorge; Drehmer, EraciIntroducción: La esclerosis lateral amiotrófica (ELA) es una patología neurodegenerativa crónica y progresiva, que produce la muerte de las motoneuronas. Deriva en pérdida de peso, de masa muscular e incremento de deficiencias nutricionales. Existe relación entre la ingesta nutricional y la patogénesis de la ELA. El objetivo de este análisis fue describir las características sociodemográficas, antropométricas y clínicas junto con la ingesta nutricional en una muestra de pacientes portugueses afectados de ELA. Material y Métodos: Se realizó una anamnesis clínica breve. El peso corporal fue evaluado siguiendo el protocolo de la International Society for the Advancement of Kinanthropometry (ISAK) y la talla mediante el expediente clínico del paciente. Se realizó una anamnesis dietético-nutricional y un registro dietético. La ingesta nutricional se analizó con el software Nutrición y Salud® y se comparó con las ingestas dietéticas de referencia (IDR). El índice de adecuación nutricional se consideró inferior a las recomendaciones cuando fue ≤80%. Resultados: Fueron analizados 13 pacientes (7 hombres) con edades comprendidas entre los 53-83 años. El 69,20% presentó ELA bulbar. Un 54% presentó normopeso. Todos los pacientes presentaron disfagia y disartria y un 84,62% constipación. En comparación a las IDR, en ambos sexos, se identificó deficiencia nutricional de fibra, vitamina D, E, B8, B9, calcio, magnesio y yodo, acompañado de un exceso nutricional de proteínas, lípidos, ácidos grasos saturados y sodio. Conclusiones: El hallazgo de estas deficiencias nutricionales es relevante ya que los nutrientes involucrados influyen sobre los mecanismos patogénicos de la ELA, porque son antioxidantes, antiinflamatorios y contribuyen al normal funcionamiento de las motoneuronas. Los excesos nutricionales identificados se relacionan con estrés oxidativo, inflamación y mayor riesgo de ELA. Son necesarios más estudios en muestras de mayor tamaño para contribuir a la comprensión de la relación entre las carencias y excesos nutricionales y el riesgo de desarrollo y/o progresión de la enfermedad.
- Low serum chromium is rare in patients that underwent endoscopic gastrostomy for long term enteral feedingPublication . Santos, Carla Adriana; Fonseca, Jorge; Carolino, Elisabete; Guerreiro, António SousaABSTRACT - Background: Patients that underwent Percutaneous Endoscopic Gastrostomy (PEG) present with protein-energy malnutrition. Trace elements are required in small quantities and Chromium (Cr) displays a major role in the metabolism. Objective: This study aims to evaluate Cr levels and its relationship with serum proteins, BMI and underlying diseases during the first 3 months of PEG feeding. Methods: Prospective observational study during 3-months, when PEG was performed (T0), after 4 (T1), and 12 weeks (T3). Initial evaluation included: age, gender, underlying disease, NRS-2002, BMI, serum albumin, transferrin and Cr concentration. At T1 and T3 a blood sample was collected for Cr, albumin and transferrin. A Graphite Furnace Atomic Absorption Spectroscopy was used to assess Cr. According with the underlying disease, patients were divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). All patients were fed with homemade meals. Results: A one hundred and twenty-nine patients (80 males), 26-95 years old were studied: HNC-52; ND-77. The observed data included low mean values of BMI from 71 patients; low Cr-8, low albumin-70, low transferrin-85 and 57 with both proteins low. Albumin was associated with survival time ( P =0.024) and there was a significant correlation between albumin and Cr (r=0.217, P =0.012). A good evolution of Cr and proteins values was observed, with no low Cr levels at T3. Conclusion: Low serum Cr is rare in PEG-patients, with no relationship to other studied parameters. For the minority of patients displaying low Cr before gastrostomy, homemade PEG meals seem to be effective.
- A malnutrição associada à doença e as suas repercussões em PortugalPublication . Marinho, Anibal; Lopes, Ana; Sousa, Gabriela; Antunes, Henedina; Fonseca, Jorge; Mendes, Lino; Carvalho, Mamede de; Veríssimo, Manuel Teixeira; Carvalho, Nuno; Alves, Paula; Alves, PauloA malnutrição associada à doença é frequente do ponto de vista clínico, apresentando elevada morbilidade, mortalidade e impacto na qualidade de vida, em especialidades como a medicina interna, a oncologia, a neurologia, a gastroenterologia e a pediatria, entre outras. Estudos realizados em Portugal estimam existirem cerca de 40% de doentes em risco nutricional à data da admissão hospitalar, dependendo do estadio da doença e do grau/severidade. O custo da hospitalização destes doentes, é cerca de 20% superior ao dos doentes com o mesmo grupo de diagnóstico homogéneo, mas sem risco nutricional associado. No nosso país, o acesso dos doentes malnutridos a avaliação, aconselhamento e tratamento nutricional adequados ainda é limitado, mesmo em ambiente hospitalar. Um conhecimento detalhado da malnutrição associada à doença nas referidas especialidades, permitiria uma melhor caracterização da situação em Portugal, e permitiria estabelecer uma estratégia de intervenção clínica e terapêutica, para melhorar este panorama e as suas consequências no nosso país.
- Selenium in dysphagic patients who underwent endoscopic gastrostomy for long term enteral feedingPublication . Santos, Carla Adriana; Fonseca, Jorge; Carolino, Elisabete; Lopes, Teresa; Guerreiro, António SousaBackground and aims - Endoscopic gastrostomy (PEG) patients usually present protein-energy malnutrition, but little is known about selenium deficiency. We aimed to assess serum selenium evolution when patients underwent PEG, after 4 and 12 weeks. We also evaluated the evolution of albumin, transferrin and Body Mass Index and the influence of the nature of the underlying disease. Methods - A blood sample was obtained before PEG (T0), after 4 (T1) and 12 (T3) weeks. Selenium was assayed using GFAAS (Furnace Atomic Absorption Spectroscopy). The PEG patients were fed through homemade meals. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). Results - We assessed 146 patients (89 males), between 21-95 years old: HNC-56; ND-90. Normal values of selenium in 79% (n=115); low albumin in 77, low transferrin in 94, low values for both serum proteins in 66. Low BMI in 78. Selenium has slow evolution, with most patients still displaying normal Selenium at T3 (82%). Serum protein levels increase from T0 to T3, most patients reaching normal values. The nature of the underlying disease is associated with serum proteins but not with selenium. Conclusions - Low serum selenium is uncommon when PEG is performed, after 4 and 12 weeks of enteral feeding and cannot be related with serum proteins levels or dysphagia cause. Enteral nutrition using customized homemade kitchen meals is satisfactory to prevent or correct Selenium deficiency in the majority of PEG patients.
- Serum copper evolution in patients that underwent endoscopic gastrostomy for long term enteral feedingPublication . Santos, Carla Adriana; Fonseca, Jorge; Carolino, Elisabete; Lopes, Teresa; Guerreiro, António SousaBackground and aims: Copper (Cu) is a well studied trace element but little is known about Cu evolution in long term endoscopic gastrostomy (PEG) feeding. We aimed to evaluate the evolution serum Cu since the gastrostomy until 12 weeks after the procedure in PEG patients fed with homemade meals. Methods: A prospective observational study was performed evaluating serum copper, albumin, transferrin and body mass index (BMI) at the time of the gastrostomy, 4 weeks and 12 weeks after. Data also included age, gender, NRS 2002 and nature of the underlying disease causing dysphagia: head and neck cancer (HNC) or neurological dysphagia (ND). After gastrostomy, patients were fed with homemade PEG meals. Results: One hundred and forty-six patients enrolled, 89 men, aged 21-95 years, 90 with neurologic dysphagia (ND), and 56 with head and neck cancer (HNC). 78 (53%) showed low BMI. Initially, Cu ranged 42-160 μg/dl (normal: 70-140 μg/dl); 130 patients (89%) presented normal Cu, 16 (11%) presented hypocupremia, 53% low albumin (n = 77), and 94 (65%) low transferrin. After 4 weeks, 93% presented normal Cu, 7% presented hypocupremia, low albumin was present in 34%, and low transferrin in 52%. After 12 weeks, 95% presented normal Cu, 5% presented hypocupremia, low albumin was present in 25%, and low transferrin in 32%. Comparing age, gender, underlying disease, BMI, albumin and transferrin, there were no significant differences on serum Cu. Conclusions: Most patients present normal serum Cu when gastrostomy is performed. For patients presenting hypocupremia before gastrostomy, homemade meals are effective for normalizing serum Cu.
- Serum trace elements in dysphagic gastrostomy candidates before endoscopic gastrostomy for long term enteral feedingPublication . Santos, Carla Adriana; Fonseca, Jorge; Carolino, Elisabete; Sousa Guerreiro, AntónioBackground & aims - Patients who underwent endoscopic gastrostomy (PEG) present protein-energy malnutrition, but little is known about Trace Elements (TE), Zinc (Zn), Copper (Cu), Selenium (Se), Iron (Fe), Chromium (Cr). Our aim was the evaluation of serum TE in patients who underwent PEG and its relationship with serum proteins, BMI and nature of underlying disorder. Methods - A prospective observational study was performed collecting: patient's age, gender, underlying disorder, NRS-2002, BMI, serum albumin, transferrin and TE concentration. We used ferrozine colorimetric method for Fe; Inductively Coupled Plasma-Atomic Emission Spectroscopy for Zn/Cu; Furnace Atomic Absorption Spectroscopy for Se/Cr. The patients were divided into head and neck cancer (HNC) and neurological dysphagia (ND). Results - 146 patients (89 males), 21–95 years: HNC-56; ND-90. Low BMI in 78. Low values mostly for Zn (n = 122) and Fe (n = 69), but less for Se (n = 31), Cu (n = 16), Cr (n = 7); low albumin in 77, low transferrin in 94 and 66 with both proteins low. Significant differences between the groups of underlying disease only for Zn (t140.326 = −2,642, p < 0.01) and a correlation between proteins and TE respectively albumin and Zn (r = 0.197, p = 0.025), and albumin and Fe (r = 0.415, p = 0.000). Conclusions - When gastrostomy was performed, patients display low serum TE namely Zn, but also Fe, less striking regarding others TE. It was related with prolonged fasting, whatever the underlying disease. Low proteins were associated with low TE. Teams taking care of PEG-patients should use Zn supplementation and include other TE evaluation as part of the nutritional assessment of PEG candidates.
- Serum zinc evolution in dysphagic patients that underwent endoscopic gastrostomy for long term enteral feedingPublication . Santos, Carla Adriana; Fonseca, Jorge; Lopes, Maria Teresa Martins; Carolino, Elisabete; Guerreiro, António SousaBackground and objectives - Patients undergoing endoscopic gastrostomy (PEG) present with protein-energy malnutrition (PEM) but little are known about zinc status. Our aim was to evaluate serum zinc, its relationship with serum proteins and with the nature of the underlying disorder, during the first 3 months of PEG feeding. Methods and study design - Prospective observational study during a 3-month period after gastrostomy. Data were collected at initial PEG procedure (T0), after 4 (T1) and 12 weeks (T3). Initial evaluation included: age, gender, a disorder causing dysphagia, Neurological Dysphagia (ND) or Head and Neck Cancer (HNC), NRS-2002, BMI, albumin, transferrin, zinc. At T1 and T3, a blood sample was collected for zinc, albumin, transferrin. Serum zinc evaluation was performed with ICP-AES - Inductively Coupled Plasma-Atomic Emission Spectroscopy. Patients were fed with homemade meals. Results - A total of 146 patients (89 males), 21-95 years were studied: HNC-56, ND-90 and low BMI in 78. Initial low zinc in 122; low albumin in 77, low transferrin in 94; low values for both proteins in 66. Regarding the serum protein evolution, their levels increase T0-T3, most patients reaching normal values. zinc has a slower evolution, most patients still displaying low zinc at T3. Significant differences between the 3 moments for zinc (p=0.011), albumin (p<0.0001) and transferrin (p=0.014). Conclusion - PEG patients are prone to PEM and zinc deficiency. Most patients present decreased zinc, suggesting that zinc deficiency is common in PEG candidates and is not corrected during 3 months of enteral feeding. Zinc deficiency should be expected and teams taking care of PEG patients should use zinc supplementation.
- Vitamin D in dysphagic patients who have undergone endoscopic gastrostomy for long-term enteral feedingPublication . Santos, Carla Adriana; Nunes, Gonçalo; Barata, Ana Teresa; Fonseca, JorgeObjective: Vitamin D plays a major role in biological processes. Its deficiency is associated with increased morbidity and mortality. Patients who have undergone endoscopic gastrostomy (PEG) present with protein-energy malnutrition, and may be at risk for Vitamin D deficiency, due to their age, less sunlight exposure, and lower dietary intake. We aimed to determine the prevalence of hypovitaminosis D in PEG patients, its change under PEG-feeding, and its relationship with serum proteins and risk factors for Vitamin D deficiency. Methods: This was a prospective observational study, over 4 weeks, after gastrostomy. Data were collected at the initial PEG procedure (T0), and after 4 weeks (T1). Initial evaluation included age, gender, underlying disorder, NRS-2002, BMI, serum albumin, transferrin, and Vitamin D. At T1 we assessed Vit. D, albumin, and transferrin. Vitamin D was performed with Electrochemiluminescence through Elecsys 2010 assay. Patients were fed with blended homemade meals. Results: 200 patients (118 males), 22-92 years of age, were studied. There were initial low values for Vit. D (181), albumin (96), transferrin (121), and BMI (124). A correlation was found between Vit. D and serum albumin (r=0.49, p=0.005) but not with transferrin (r=0.26, p=0.195). At T1 the subgroup who had Vit. D levels assessed (n=48) was part of the initial study group maintained low levels of Vitamin D despite nutritional intervention. Conclusion: We recommend systematic Vitamin D supplementation of PEG-fed patients using homemade meals or at least screening for hypovitaminosis D as a routine part of their care.
