Multidisciplinary Approach for Weight Regain-how to Manage this Challenging Condition: an Expert Review.

Weight regain is a multifactorial condition that affects many patients following bariatric surgery. The purpose of the paper is to review the multidisciplinary approach for the management of weight regain. We performed a search in current clinical evidence regarding the causes, consequences, and treatments of weight regain. The multidisciplinary approach with periodic monitoring is of fundamental importance to prevent or treat weight regain. Several therapeutic options are ranging from nutritional to surgical options, which should be tailored according to patients' anatomy, lifestyle behavior, and compliance. Specialized multidisciplinary care is the key to achieve optimal long-term weight loss and maintenance goals following bariatric surgery.

Tumor Necrosis Factor Alpha Inhibitors Did Not Influence Postoperative Morbidity After Elective Surgical Resections in Crohn's Disease.

BACKGROUND: The real impact of anti-tumor necrosis alpha (TNF) therapy in postoperative complications after intestinal resections in Crohn's disease (CD) still needs to be determined. AIMS: To compare the postoperative complication rates after elective intestinal resections in CD patients, with or without previous exposure to anti-TNF therapy. METHODS: This was a retrospective and observational study, with elective intestinal resections for CD (emergency procedures were excluded). Patients were allocated in two groups according to preoperative anti-TNF status. Surgical and medical complications were analyzed and subsequently compared between the groups. RESULTS: A total of 123 patients were included (71 with and 52 without preoperative anti-TNF). The groups were considered homogeneous, except for perianal CD, previous azathioprine, and stomas. There was no significant difference between the groups regarding overall surgical complications (32.69% in anti-TNF- vs. 39.44% in anti-TNF+ patients, p = 0.457) or overall medical complications (21.15 vs. 21.13%, respectively, p = 1.000). In univariate analysis, previous steroids, perianal CD, and stomas were considered risk factors for surgical complications, and previous steroids and hypoalbuminemia for medical complications. In multivariate analysis, previous steroids were associated with higher rates of surgical and medical complications, while hypoalbuminemia was associated with higher medical complication rates. CONCLUSIONS: There was no influence of the previous use of anti-TNF agents in postoperative surgical and medical complication rates in elective intestinal resections for CD. Previous steroids and hypoalbuminemia were associated with higher complication rates. This was the first case series of the literature describing outcomes in exclusively elective operations.

Fatores de risco associados ao prognóstico de adultos internados com pneumonia adquirida na comunidade / Risk factors that influence the prognosis of community-acquired pneumonia in hospitalized adults

OBJETIVO: Avaliar parâmetros nutricionais no prognóstico de adultos internados em hospital geral, com pneumonia adquirida na comunidade. MÉTODOS: Foram estudados prospectivamente 61 casos da doença e analisadas variáveis: sociodemográficas, morbidade, hábitos de vida, antropométricas (índice de massa corporal, circunferência da cintura, porcentagem de gordura, porcentagem de perda de peso), bioquímicas (ureia, creatinina, albumina no momento da internação e no 18º dia e pré-albumina (na internação, quarto, oitavo e 18º dia) e evolução (menos de 10, mais de 10 dias de internação e/ou óbito). RESULTADOS: As variáveis antropométricas apresentaram-se diferentes entre os sexos, porém não se associaram com a má evolução da doença. Os níveis séricos de albumina e de pré-albumina encontraram-se baixos na internação em 80,3% e 86,9% dos casos, respectivamente. Após ajuste logístico, o hábito de fumar (OR:1,23, IC:1,0-12,1), a presença de mais de uma imagem ou derrame pleural no exame radiológico de tórax (OR: 1,4 IC: 1,24-15,3) e a pré-albumina baixa no quarto dia (OR:6,1 IC:1,7-22,5) foram preditores de má evolução do quadro de pacientes com pneumonia adquirida na comunidade. CONCLUSÃO: Indicador bioquímico nutricional como a pré-albumina, o tabagismo e mais de uma imagem no exame radiológico de tórax são parâmetros de gravidade de pneumonia úteis na condução clínica de infecções.

OBJECTIVE: The present study assessed the influence of nutritional parameters on the prognosis of community-acquired pneumonia in adults admitted to a general hospital. METHODS: A total of 61 individuals with community-acquired pneumonia were studied prospectively and the following data analyzed: sociodemographic variables, morbidity, life habits, anthropometric variables (body mass index, waist circumference, percentage of body fat, percentage of weight lost), biochemical variables (urea, creatinine, albumin on admission and 18 days later, prealbumin on admission and 4, 8 and 18 days later), and outcome (hospital stay shorter than 10 days, longer than 10 days and/or death). RESULTS: Anthropometric variables differed between genders but were not associated with poor outcome. Albumin and prealbumin levels were low on admission in 80.3% and 86.9% of the cases, respectively. Logistic regression showed that smoking (OR:1.23; CI:1.0-12.1), more than one finding or pleural effusion on chest radiographs (OR:1.4; CI:1.24-15.3) and low prealbumin on day 4 (OR:6.1; CI:1.7-22.5) predicted a poor outcome for patients with community-acquired pneumonia. CONCLUSION: Nutrition-related biochemical markers, such as low prealbumin, smoking and more than one finding on chest radiographs, indicate severe pneumonia and are useful for deciding treatment strategy.

[Preliminary comparison between phalangeal quantitative ultrassonography and bone densitometry for bone mass evaluation in adolescents]. / Comparação preliminar entre ultrassonografia quantitativa de falanges e densitometria óssea na avaliação da massa óssea em adolescentes.

OBJECTIVE: To evaluate the association between quantitative ultrasonography at hand phalanges (QUS) and dual energy X-ray absorptiometry (DXA), and between these methods with food intake and history of bone fractures. SUBJECTS AND METHODS: After two years of follow up of 270 schoolchildren, 10 of them, who showed bone mass below - 2 SD in QUS, were included in the present study. Laboratory results and DXA data were analyzed. RESULTS: Bone mass evaluated by DXA at L1-L4 ranged from -2.8 to -1.1 SDS, and whole body bone mass, from -2.9 to -1.2 SDS. Three children had history of non-pathological bone fractures. Dietary assessment showed low intake of calcium in 10 cases, of phosphorus in 6, and of vitamin D in 8 cases. There were no differences among the cases of bone mass below-2 SD in any of the three used methods. There was no association between history of bone fractures and food intake, and between these evaluations and bone mass. CONCLUSION: In this small group of schoolchildren there was an association between the methods QUS and DXA. However, there was no association between bone mass and the history of bone fractures, or calcium, phosphorus and vitamin D intake.

Comparação preliminar entre ultrassonografia quantitativa de falanges e densitometria óssea na avaliação da massa óssea em adolescentes / Preliminary comparision between phalangeal quantitative ultrassonography and bone densitometry for bone mass evaluation in adolescents

OBJETIVO: Avaliar associação entre ultrassonografia quantitativa de falanges da mão (QUS) e a densitometria por absorção de raio-X de dupla energia (DXA) e desses com os históricos alimentar e de fraturas. SUJEITOS E MÉTODOS: Após dois anos de acompanhamento de 270 escolares, 10 com massa óssea por QUS abaixo de -2 DP foram incluídos no estudo e avaliados com DXA. RESULTADOS: A massa óssea por DXA de L1-L4 variou de -2,8 a -1,1 DP e de corpo inteiro -2,9 e -1,2. Três estudantes apresentaram fraturas. Baixa ingestão de cálcio foi observada nos 10 casos, de fósforo em 6 e de vitamina D em 8. Não houve diferença entre os casos com massa abaixo de -2 DP nos três métodos de avaliação. Não foi observada associação entre as fraturas e o histórico alimentar, nem com os valores de massa óssea. CONCLUSÃO: Neste pequeno grupo de adolescentes houve associação entre QUS e DXA, porém sem associação entre essas avaliações e as fraturas e a ingestão de cálcio, fósforo e vitamina D.
