Presurgery nutrition

Purpose: To identify and evaluate changes in the ocular surface in obese patients with bariatric surgery. Methods: The study included 89 randomly selected patients; 81 (91.0%) were women, 35 were preoperative, 32 were included 0-12 months after surgery, and 22 were included >12 months after surgery. All patients completed a dry eye-specific questionnaire and were evaluated by the tear ferning test, tear-film breakup time (BUT), Schirmer's test I, examination of the ocular surface by 1% rose Bengal staining, and impression cytology...

BACKGROUND: Data regarding long-term nutritional deficiencies following laparoscopic sleeve gastrectomy (LSG) are scarce. OBJECTIVES: To assess the prevalence of nutritional deficiencies and supplement consumption 4 years post-LSG. SETTING: Hebrew University, Israel. METHODS: Data were collected prospectively from preoperative and 1 and 4 years postoperative including anthropometric parameters, biochemical tests, and supplement intake...

Bariatric surgery is currently the most effective treatment for morbid obesity and its associated metabolic complications. To ensure long-term postoperative success, patients must be prepared to adopt comprehensive lifestyle changes. This review summarizes the current evidence and expert opinions with regard to nutritional care in the perioperative and long-term postoperative periods. A literature search was performed with the use of different lines of searches for narrative reviews. Nutritional recommendations are divided into 3 main sections: 1 ) presurgery nutritional evaluation and presurgery diet and supplementation; 2 ) postsurgery diet progression, eating-related behaviors, and nutritional therapy for common gastrointestinal symptoms; and 3 ) recommendations for lifelong supplementation and advice for nutritional follow-up...

BACKGROUND: Food cravings and consumption of craved foods after Roux-en-Y gastric bypass (RYGB) are poorly understood. Food cravings after bariatric surgery may explain why some patients fail to change eating behaviors after RYGB, and understanding these cravings may provide better information for nutritional counseling to either enhance weight loss or prevent weight regain. OBJECTIVES: To study cravings in RYGB patients and compare them with cholecystectomy (CC) control patients...

BACKGROUND: Perioperative nutrition and preoperative oral carbohydrate loading (CHL) have a beneficial impact on the outcomes of gastrointestinal oncological surgery. However no data exists on their effect on morbidly obese patients. OBJECTIVES: Our aim was to establish the short-term and long-term impact of these modalities, notably on metabolically active lean body mass (LBM) - an important factor in maintaining long-term weight loss. METHODS: Patients undergoing laparoscopic Roux-en-Y gastric bypass were randomized to standard management or intervention: CHL drinks consumed 12 and 2 hours presurgery, and immediate postoperative peripheral parenteral nutrition...

BACKGROUND: Neoadjuvant chemotherapy is an accepted standard for locally advanced esophagogastric junction adenocarcinoma. However, the dysphagia frequently associated with this condition may interfere with patient tolerance of this treatment. In many centers, invasive tube feeding, placed either endoscopically, radiographically, or surgically, is used to address this issue, but it can cause significant morbidity. We sought to determine if an approach of goal-directed dietary counseling and appropriately timed neoadjuvant chemotherapy could obviate the need for invasive tube feeding...

OBJECTIVE: The growing prevalence of severe obesity, combined with the failure of conservative treatments, has led to a significant spread of bariatric surgical procedures. The aim of this study was to emphasize the need of adequate presurgery patient selection and close follow-up after malabsorptive procedures for bariatric surgery. METHODS: The study retrospectively evaluated 25 (20 F, 5 M; mean age 43 ± 13 y) obese patients (mean weight before intervention 134 ± 30...

BACKGROUND: Nutritional status during pregnancy and the effects of nutritional deficiencies on pregnancy outcomes after bariatric surgery is an important issue that warrants further study. The objective of this study was to investigate pregnancy outcomes and nutritional indices after restrictive and malabsorptive procedures. METHODS: We investigated pregnancy outcomes of 113 women who gave birth to 150 children after biliopancreatic diversion (BPD), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) between June 1994 and December 2011...

OBJECTIVES: The aim of the study was to develop a multistranded pragmatic rehabilitation programme for operable lung cancer patients, that looks into feasibility, process indicators, outcome measures, local adaptability, compliance and potential cost benefit. METHODS: An outpatient-based complex intervention, rehabilitation for operated lung cancer (ROC) programme, was developed to optimize physical status, prepare for the inpatient journey and support through recovery after surgery...

Primary prevention guidelines recommend calculation of lifetime cardiovascular disease (CVD) predicted risk in patients who may not meet criteria for high short-term (10-year) Adult Treatment Panel III risk for coronary heart disease (CHD). Extreme obesity and bariatric surgery are more common in women who often have low short-term predicted CHD risk. The distribution and correlates of lifetime CVD predicted risk, however, have not yet been evaluated in bariatric surgical candidates. Using established 10-year (Adult Treatment Panel III) CHD and lifetime CVD risk prediction algorithms and presurgery risk factors, participants from the Longitudinal Assessment of Bariatric Surgery-2 study without prevalent CVD (n = 2,070) were stratified into 3 groups: low 10-year (<10%)/low lifetime (<39%) predicted risk, low 10-year (<10%)/high lifetime (≥39%) predicted risk, and high 10-year (≥10%) predicted risk or diagnosed diabetes...

BACKGROUND: The risks and benefits of bariatric surgery have rarely been evaluated in large multiyear patient samples. This study identifies the short- and long-term impact of bariatric surgery on comorbidities and medication use among obese patients. METHODS: A comprehensive analysis of 5,502 obese patients who underwent bariatric surgery was performed. Submissions of reimbursement claims, including diagnostics and medication use, were compared in the 90 days preceding the surgery and 30 up to 1,110 days following the surgery...

BACKGROUND: Inflammatory status underlying obesity seems to be implicated in several aspects of metabolic syndrome. OBJECTIVE: This study aimed to investigate the association between weight loss achieved by laparoscopic gastric banding (LAGB) surgery, chronic inflammatory markers, and nutritional state. METHODS: Thirty-two morbid obese females were enrolled in the study and evaluated at baseline, 1 and 18 months after LAGB surgery. Serum immunoglobulin G (IgG), IgA, IgM, C-reactive protein (CRP), haptoglobin, alpha-1 antitrypsin, total proteins, albumin, prealbumin, transferrin, ferritin, and transferrin soluble receptor were evaluated...

PURPOSE: The rate of bariatric surgery in the United States has risen significantly in the past decade as the prevalence of extreme obesity continues to increase. Although bariatric surgery is an effective therapeutic modality for extreme obesity, it is associated with risk factors and select oral health conditions. This case study describes a patient with a significant increase in dental caries after having gastric bypass surgery. It was hypothesized that bariatric patients may be at an increased risk for caries due to the need for more frequent and prolonged meals throughout the day...

PURPOSE: The present study was focused on a comparison of postsurgical oropharyngeal swallowing efficiency and medical status indicators. PATIENTS AND METHODS: The swallowing function was assessed in 25 patients (18 males and 7 females) with oral cancer. The swallowing function was assessed preoperatively and 1, 6, and 12 months and in some cases more than 24 months after surgery. Assessment of the swallowing function consisted of videofluoroscopic evaluation (oropharyngeal swallow efficiency; OPSE) and details of the method of nutrition, diet level, nutritional condition, and occurrence of pneumonia...

INTRODUCTION: Herbal medicine is being frequently used by patients around the world. Several products may interact with ordinary medicine, so it is important for doctors to know what kind of herbal medicines their patients take. MATERIAL AND METHODS: A questionnaire was given to presurgery patients during a two-month period. RESULTS: A total of 115 consecutive patients responded, 69 women (60%) and 46 men (40%). 50.4% had taken or still took herbal medicine, with the following distribution of gender: women 69...

The orexigenic peptide, ghrelin, is regulated by acute and chronic nutritional state. Although exogenously administered ghrelin stimulates pituitary GH secretion, little is known about the role of ghrelin in endogenous GH secretion or how high GH and IGF-I levels in acromegaly could affect ghrelin secretion and vice versa. Therefore, we evaluated fasting and post oral glucose tolerance test serum ghrelin levels in 19 patients with active acromegaly at baseline and after either surgery in 9 of these or administration of long-acting octreotide (Sandostatin LAR) in the other 10 patients...

OBJECTIVES: To describe the sequential changes in the growth hormone (GH)/insulin-like growth factors axis and their relationship with nitrogen balance in children following cardiac surgery. DESIGN: Prospective, descriptive study. SETTING: Pediatric intensive care unit of a university hospital. PATIENTS: Twenty three postoperative cardiac surgical patients after bypass. INTERVENTIONS: Blood and urine samples were taken on days 1, 2, and 7 of pediatric intensive care unit admission...

Interest in the modulation of renal diseases by polyunsaturated fatty acids (PUFA) led this group to examine the effects of borage oil (BO) and corn oil (CO) in the rat 5/6-renal-ablation model. BO is a rich source of gamma-linolenic acid (GLA; 18:3n-6), which is elongated to dihomogamma-linolenic acid (DGLA; 20:3n-6). CO is a rich source of linoleic acid (LA; 18:2n-6), a GLA and arachidonic acid (AA; 20:4n-6) precursor. The purpose of this study was to assess whether an increased DGLA:AA ratio as provided by BO would confer benefits beyond those provided by LA present in corn oil...

The rate of energy expenditure was repeatedly measured by indirect calorimetry both in the basal state (BMR) and in the resting fed state (RMR) in 8 middle-aged male patients operated for oropharyngeal cancer. In the postsurgical phase, two sequential energy levels were administered by nasogastric tube: (1) a 'maintenance' level (days 3-5) at 1.4 X measured presurgery BMR; (2) a 'supramaintenance' level (days 6-9) at 1.7 X measured BMR on day 6. Before surgery the patients had a BMR averaging (23.7 +/- 1.0 kcal/kg...

Hormonal and substrate profiles and urinary nitrogen and urea excretion were measured in 78 underweight patients admitted for surgical investigation, who were placed into either a normo- or a hyperketonemic group, depending upon their levels of acetoacetate and beta-hydroxybutyrate. The two groups were otherwise similar in terms of weight loss, arm muscle circumference, triceps skinfold thickness, and serum protein levels. Before surgery only one-quarter of them were hyperketonemic displaying mean glucose, insulin, and glucagon levels characteristic of starvation-adaption, and excreted significantly less urinary nitrogen than in normoketonemic group...
