A Recusa Alimentar na Pessoa Idosa

A ingestão de alimentos é uma necessidade humana básica, para a manutenção da vida e da saúde. Uma alimentação equilibrada permite satisfazer as necessidades qualitativas e quantitativas em nutrientes essenciais, de forma a que cada pessoa possa manter a sua actividade física, social e afectiva. Com o envelhecimento dão-se alterações a nível biológico, fisiológico, social e económico que podem alterar os hábitos alimentares do indivíduo idoso. A recusa alimentar pode ser de etiologia multifactorial, motivando frequentemente a recorrer ao serviço de urgência e internamento da pessoa idosa. Esta problemática preocupa-nos, como enfermeiros, pois muitas vezes persiste a dúvida da intervenção mais adequada a tomar. Será a alimentação por sonda nasogástrica a primeira e única opção?

Origem Anómala da Artéria Coronária Esquerda a Partir da Artéria Pulmonar

OBJECTIVE: To assess the frequency and severity of the anomalous origin of the left coronary artery (ALCA) from the pulmonary artery (PA). DESIGN OF THE STUDY: Prospective study of case series between March 1991 and December 1994. SETTING: Referral-based Paediatric Cardiology Department of a Tertiary Care Center. PATIENTS AND METHODS: Five consecutive patients (pts) with anomalous origin of the LCA from the PA; there were three infants aged 4 months and two children one 8 year and one 9 year old. There were three girls and two boys. All pts had clinical and 2D-echo and Doppler investigation prior to cardiac catheterization (CC). Indication for CC was based in the association of symptoms and signs of myocarditis or dilated cardiomyopathy of acute or subacute onset and electrocardiographic (ECG) signs of ischemia in infants. In older patients (pts) diagnosis was suspected mainly from ECG. During CC in all pts, aortograms and when necessary selective coronary angiograms were performed. Surgical correction was performed in all children. In two pts stress exercise ECG and stress Thallium studies before and after surgery were performed. RESULTS: two pts had "adult" an three had "infantile" type of ALCA from the PA. CC was performed and diagnosis was confirmed at surgery in all cases. In one child, correct diagnosis was made by ECO prior to CC and in one case LCA to PA fistula was suspected on Colour-Doppler study. No complications were attributed to CC. Several types of surgery were performed: reimplantation of the ALCA from the PA to the aorta (three pts); tunnel connection of the aorta to the ALCA via the PA (one pt) and left internal mammary to LCA anastomosis (one pt). Two infants died intraoperatively due to extensive myocardial infarction and poor left ventricular function. All the three survivors are asymptomatic after a mean follow up of 34 months. Two oldest pts are currently in New York Heart Association functional class I with normal ECG and improved myocardial perfusion on Thallium scan despite almost total occlusion of LCA at the site of implantation in the aorta as diagnosed on coronary angiogram. CONCLUSIONS: ALCA from PA is associated with major morbidity and mortality. Diagnosis should be suspected in pts with unexplained myocardial ischemia on ECG and even more if it is associated to clinical signs of dilated cardiomyopathy or myocarditis. Careful assessment on ECO and pulsed Doppler and colour flow mapping should make the diagnosis in most cases. Although surgery can be performed based only on ECO diagnosis, we strongly advise for angiography in all cases as in our experience there are false negative diagnosis by ECO. Preoperative Thallium studies can be useful for the selection of the type of surgery as pts with very little viable myocardium will not survive the establishment of a direct systemic to coronary blood flow and may be candidates for heart transplantation.

Predictive Variables Affecting Transfusion Requirements in Orthotopic Liver Transplantation

INTRODUCTION AND AIMS: Adult orthotopic liver transplantation (OLT) is associated with considerable blood product requirements. The aim of this study was to assess the ability of preoperative information to predict intraoperative red blood cell (RBC) transfusion requirements among adult liver recipients. METHODS: Preoperative variables with previously demonstrated relationships to intraoperative RBC transfusion were identified from the literature: sex, age, pathology, prothrombin time (PT), factor V, hemoglobin (Hb), and platelet count (plt). These variables were then retrospectively collected from 758 consecutive adult patients undergoing OLT from 1997 to 2007. Relationships between these variables and intraoperative blood transfusion requirements were examined by both univariate analysis and multiple linear regression analysis. RESULTS: Univariate analysis confirmed significant associations between RBC transfusion and PT, factor V, Hb, Plt, pathology, and age (P values all < .001). However, stepwise backward multivariate analysis excluded variables Plt and factor V from the multiple regression linear model. The variables included in the final predictive model were PT, Hb, age, and pathology. Patients suffering from liver carcinoma required more blood products than those suffering from other pathologies. Yet, the overall predictive power of the final model was limited (R(2) = .308; adjusted R(2) = .30). CONCLUSION: Preoperative variables have limited predictive power for intraoperative RBC transfusion requirements even when significant statistical associations exist, identifying only a small portion of the observed total transfusion variability. Preoperative PT, Hb, age, and liver pathology seem to be the most significant predictive factors but other factors like severity of liver disease, surgical technique, medical experience in liver transplantation, and other noncontrollable human variables may play important roles to determine the final transfusion requirements.

De Novo Hypertension and Decline of Renal Function in a Young Woman with Systemic Lupus Erythematosus and Antiphospholipid Syndrome

Antiphospholipid syndrome nephropathy and lupus nephritis have similar clinical and laboratory manifestations and achieving the accuracy of diagnosis required for correct treatment frequently necessitates a kidney biopsy. We report the case of a 29-year-old woman referred to the nephrology service for de novo hypertension, decline of renal function and proteinuria. She had had systemic lupus erythematosus and antiphospholipid syndrome since the age of 21 and was taking oral anticoagulation. Two weeks later, after treatment of hypertension and achievement of adequate coagulation parameters, a percutaneous renal biopsy was performed. The biopsy revealed chronic lesions of focal cortical atrophy, arterial fibrous intimal hyperplasia and arterial thromboses, which are typical features of antiphospholipid syndrome nephropathy. We describe the clinical manifestations and histopathology of antiphospholipid syndrome nephropathy and review the literature on renal biopsy in patients receiving anticoagulation.

Angioplastia Primária na Mulher: Realidade Nacional

Objetivos: A mortalidade na mulher após angioplastia primária (ICP-P) é superior à do homem. Contudo, permanece contraditório o papel do sexo poder ser fator de risco independente para mortalidade no contexto de enfarte agudo do miocárdio com supradesnivelamento de ST (EAMST). Com base no Registo Nacional de Cardiologia de Intervenção (RNCI),pretendemos avaliar como é que o género feminino influencia o prognóstico a curto prazo nos doentes com EAMST submetidos a ICP-P a nível nacional. Métodos: De 60 158 doentes incluídos prospetivamente no RNCI de 2002-2012, incluímos na análise 7544 doentes com EAMST tratados por ICP-P, dos quais 25% foram mulheres. Utilizámos modelos de regressão logística e ajustamento por propensity score para avaliar o impacto do sexo na mortalidade hospitalar. Resultados: As mulheres foram mais idosas (68 ± 14 versus 61 ± 13, p < 0,001), mais diabéticas(30 versus 21%, p < 0,001) e hipertensas (69 versus 55%, p < 0,001). Os homens foram revascularizados mais cedo (71 versus 63% nas primeiras 6 horas, p < 0,001). Choque cardiogénico foi mais frequente nas mulheres (7,1 versus 5,7%, p = 0,032). Estas apresentaram um pior prognóstico a curto prazo, com 1,7 x maior risco de morte intra-hospitalar (4,3 versus 2,5%; IC 95% 1,30-2,27; p < 0,001). Utilizando um modelo de regressão ajustado através de um propensity score, o sexo deixa de ser preditor de mortalidade hospitalar (OR 1,00; IC 95% 0,68-1,48; p = 1,00). Conclusões: No RNCI as mulheres com EAMST tratadas com ICP-P apresentaram maior risco cardiovascular, um acesso menos atempado a ICP-P e um pior prognóstico. Contudo, após ajustamento do risco, o género feminino deixa de ser preditor independente de mortalidade hospitalar.

Syndrome In Question

Multiple autoimmune syndrome is a rare condition, described by Humbert and Dupond in 1988. It is defined by the association of at least 3 autoimmune diseases in the same patient. Vitiligo is the most common skin condition in this syndrome. This article presents the case of a 31-year-old male with vitiligo, alopecia areata, Crohn's disease, psoriasis vulgaris and oral lichen planus. The rarity of this case is highlighted by the coexistence of four autoimmune skin diseases in association with Crohn's disease, never described in the literature.

Evolução do Rastreio da Comunicação Interventricular

De 24 de Outubro de 1969 a 31 de Dezembro de 1986 foram observadas e seguidas por comunica ção interventricular isolada em Cardiologia Pediátrica no Hospital de Santa Marta 1274 crianças, com idade compreendida entre 3 dias e 12 anos, sem síndromes, nascidas em território nacional. Seiscentas e cinquenta e nove eram do sexo masculino e 615 do sexo feminino. Dada a importância do rastreio precoce na prevenção do estabelecimento de doença vascular pulmonar com resistência arterial pulmonar fixa foi feito o estudo evolutivo anual da idade da primeira observação. Os resultados foram favoráveis a partir de 1972, verificando-se uma melhoria progressiva com aumento do número de casos /ano e diminuição da idade do rastreio, sobretudo durante os últimos 7 anos do estudo.

Defeitos da β-Oxidação Mitocondrial: Um Caso Fatal de Deficiência em 3-Hidroxi-Acil-CoA Desidrogenase de Cadeia Longa. (LCHAD)

Descreve-se um caso fatal de deficiência em 3-hidroxi-acil-CoA desidrogenase de cadeia longa (LCHAD) diagnosticado numa criança de 8 meses de idade, segunda filha de um casal jovem, saudável e consanguíneo. Os primeiros sintomas manifestaram-se aos 6,5 meses de idade ao entrar em coma hipoglicémico não cetótico do qual recupera após infusão i.v. de glucose. Detectou-se hepatomegália e posteriormente cardiomegália. A presença de acidúria 3-hidroxi-dicarboxílica foi confirmada após teste de jejum prolongado de 13th e o estudo enzimático efectuado em cultura de fibroblastos de biópsia de pele confirmou o déficit em LCHAD.

Low Socioeconomic Status is an Independent Risk Factor for Survival After Abdominal Aortic Aneurysm Repair and Open Surgery for Peripheral Artery Disease

OBJECTIVE/BACKGROUND: The association between socioeconomic status (SES), presentation, and outcome after vascular surgery is largely unknown. This study aimed to determine the influence of SES on post-operative survival and severity of disease at presentation among vascular surgery patients in the Dutch setting of equal access to and provision of care. METHODS: Patients undergoing surgical treatment for peripheral artery disease (PAD), abdominal aortic aneurysm (AAA), or carotid artery stenosis between January 2003 and December 2011 were retrospectively included. The association between SES, quantified by household income, disease severity at presentation, and survival was studied using logistic and Cox regression analysis adjusted for demographics, and medical and behavioral risk factors. RESULTS: A total of 1,178 patients were included. Low income was associated with worse post-operative survival in the PAD cohort (n = 324, hazard ratio 1.05, 95% confidence interval [CI] 1.00-1.10, per 5,000 Euro decrease) and the AAA cohort (n = 440, quadratic relation, p = .01). AAA patients in the lowest income quartile were more likely to present with a ruptured aneurysm (odds ratio [OR] 2.12, 95% CI 1.08-4.17). Lowest income quartile PAD patients presented more frequently with symptoms of critical limb ischemia, although no significant association could be established (OR 2.02, 95% CI 0.96-4.26). CONCLUSIONS: The increased health hazards observed in this study are caused by patient related factors rather than differences in medical care, considering the equality of care provided by the study setting. Although the exact mechanism driving the association between SES and worse outcome remains elusive, consideration of SES as a risk factor in pre-operative decision making and focus on treatment of known SES related behavioral and psychosocial risk factors may improve the outcome of patients with vascular disease.
