Nutritional deficiencies after Roux-en-Y gastric bypass for morbid obesity often cannot be prevented by standard multivitamin supplementation

BACKGROUND: Despite the increasing use of Roux-en-Y gastric bypass (RYGBP) in the treatment of morbid obesity, data about postoperative nutritional deficiencies and their treatment remain scarce. OBJECTIVE: The aim of this study was to evaluate the efficacy of a standard multivitamin preparation in the prevention and treatment of nutritional deficiencies in obese patients after RYGBP. DESIGN: This was a retrospective study of 2 y of follow-up of obese patients after RYGBP surgery. Between the first and the sixth postoperative months, a standardized multivitamin preparation was prescribed for all patients. Specific requirements for additional substitutive treatments were systematically assessed by a biologic workup at 3, 6, 9, 12, 18, and 24 mo. RESULTS: A total of 137 morbidly obese patients (110 women and 27 men) were included. The mean (+/-SD) age at the time of surgery was 39.9 +/- 10.0 y, and the body mass index (in kg/m(2)) was 46.7 +/- 6.5. Three months after RYGBP, 34% of these patients required at least one specific supplement in addition to the multivitamin preparation. At 6 and 24 mo, this proportion increased to 59% and 98%, respectively. Two years after RYGBP, a mean amount of 2.9 +/- 1.4 specific supplements had been prescribed for each patient, including vitamin B-12, iron, calcium + vitamin D, and folic acid. At that time, the mean monthly cost of the substitutive treatment was $34.83. CONCLUSION: Nutritional deficiencies are very common after RYGBP and occur despite supplementation with the standard multivitamin preparation. Therefore, careful postoperative follow-up is indicated to detect and treat those deficiencies.

How to prescribe nutritional support using computers.

As other intensive care unit (ICU) therapies, nutritional support has become more complex requiring tight supervision and monitoring. It has repeatedly been shown that despite awareness of guidelines and prescription of the recommended amounts of energy (25 kcal/kg), underfeeding remains a prominent problem worldwide. In patients with prolonged stays, overfeeding has also become an issue. This lack of fit between prescription and delivery is largely caused by the lack of visibility of the nutritional results to nurses and clinicians. Computerized systems have brought major improvements, mainly through the customization of nutrition relevant variables in a single place, making them visible. Another important point is the possibility to change the ICU time constant to days and weeks which is the delay relevant for nutritional changes to appear, instead of minutes and hours which are more relevant for critical care.

Norms establishment of the Diagnosis and Recommendation Integrated System (DRIS) for nutritional diagnosis of sugarcane

The objectives of this study were to establish DRIS norms for sugarcane crop, to compare mean yield, foliar nutrient contents and variance of nutrient ratios of low- and high-yielding groups and to compare mean values of nutrient ratios selected as the DRIS norms of low- and high-yielding groups. Leaf samples (analyzed for N, P, K, Ca, Mg, S, Cu, Mn and Zn contents) and respective yields were collected in 126 commercial sugarcane fields in Rio de Janeiro State, Brazil and used to establish DRIS norms for sugarcane. Nearly all nutrient ratios selected as DRIS norms (77.8%) showed statistical differences between mean values of the low- and high-yielding groups. These different nutritional balances between the low- and high-yielding groups indicate that the DRIS norms developed in this paper are reliable. The DRIS norms for micronutrients with high S²l /S²h ratio and low coefficient of variation found can provide more security to evaluate the micronutrient status of sugarcane.

Nouveaux aspects de la prise en charge de l'hypertension artérielle chez le patient insuffisant rénal chronique [New aspects of hypertension management in patients with chronic kidney disease].

Hypertension is a frequent finding in patients with chronic kidney disease. Whether primary or secondary to renal disease, hypertension remains an important risk factory for the progression of chronic kidney disease and the occurrence of cardiovascular events. The objective of this paper is to review different treatment strategies in hypertensive CKD patients, with the exclusion of patients with renal replacement therapy such as dialysis or renal transplantation.

Guidelines for specialized nutritional and metabolic support in the critically-ill patient. Update. Consensus SEMICYUC-SENPE: Oncohematological patient

Patients with cancer, irrespective of the stage of their disease, can require admission to the intensive care unit as a result of the complications of their underlying process or the surgical or pharmacological treatment provided. The cancer itself, as well as the critical status that can result from the complications of the disease, frequently lead to a high degree of hypermetabolism and inadequate energy intake, causing a high incidence of malnutrition in these patients. Moreover, cancer causes anomalous use of nutritional substrates and therefore the route of administration and proportion and intake of nutrients may differ in these patients from those in noncancer patients.

Hormonal control of spermatogenesis in men: therapeutic aspects in hypogonadotropic hypogonadism.

During the first two trimesters of intrauterine life, fetal sex steroid production is driven by maternal human chorionic gonadotropin (hCG). The HPG axis is activated around the third trimester and remains active for the first 6-months of neonatal life. This so-called mini-puberty is a developmental window that has profound effects on future potential for fertility. In early puberty, GnRH secretion is reactivated first at night and then night and day. Pulsatile GnRH stimulates both LH and FSH, which induce maturation of the seminiferous tubules and Leydig cells. Congenital hypogonadotropic hypogonadism (CHH) results from GnRH deficiency. Men with CHH lack the mini-pubertal and pubertal periods of Sertoli Cell proliferation and thus present with prepubertal testes (<4mL) and low inhibin serum levels --reflecting diminished SC numbers. To induce full maturation of the testes, GnRH-deficient patients can be treated with either pulsatile GnRH, hCG or combined gonadotropin therapy (FSH+hCG). Fertility outcomes with each of these regimens are highly variable. Recently, a randomized, open label treatment study (n=13) addressed the question of whether a sequential treatment with FSH alone prior to LH and FSH (via GnRH pump) could enhance fertility outcomes. All men receiving the sequential treatment developed sperm in the ejaculate, whereas 2/6 men in the other group remained azoospermic. A large, multicenter clinical trial is needed to definitively prove the optimal treatment approach for severe CHH.

Molecular autopsy in sudden cardiac death and its implication for families: discussion of the practical, legal and ethical aspects of the multidisciplinary collaboration.

Sudden cardiac death (SCD) is a major cause of premature death in young adults and children in developed countries. Standard forensic autopsy procedures are often unsuccessful in determining the cause of SCD. Post-mortem genetic testing, also called molecular autopsy, has revealed that a non-negligible number of these deaths are a result of inherited cardiac diseases, including arrhythmic disorders such as congenital long QT syndrome and Brugada syndrome. Due to the heritability of these diseases, the potential implications for living relatives must be taken into consideration. Advanced diagnostic analyses, genetic counselling, and interdisciplinary collaboration should be integral parts of clinical and forensic practice. In this article we present a multidisciplinary collaboration established in Lausanne, with the goal of properly informing families of these pathologies and their implications for surviving family members. In Switzerland, as in many other countries, legal guidelines for genetic testing do not address the use of molecular tools for post-mortem genetic analyses in forensic practice. In this article we present the standard practice guidelines established by our multidisciplinary team.
