Predictors of Weight Loss Maintenance following an Insurance-Sponsored Weight Management Program

Intentional weight loss among overweight and obese adults (body mass index ≥ 25 kg/m2) is associated with numerous health benefits, but weight loss maintenance (WLM) following participation in weight management programming has proven to be elusive. Many individuals attempting to lose weight join formal programs, especially women, but these programs vary widely in focus, as do postprogram weight regain results. We surveyed 2,106 former participants in a community-based, insurance-sponsored weight management program in the United States to identify the pre, during, and post-intervention behavioral and psychosocial factors that lead to successful WLM. Of 835 survey respondents (39.6% response rate), 450 met criteria for inclusion in this study. Logistic regression analyses suggest that interventionists should assess and discuss weight loss and behavior change perceptions early in a program. However, in developing maintenance plans later in a program, attention should shift to behaviors, such as weekly weighing, limiting snacking in the evening, limiting portion sizes, and being physically active every day.

Delivery room management of very low birth weight infants in Germany, Austria and Switzerland--a comparison of protocols

Surveys from the USA, Australia and Spain have shown significant inter-institutional variation in delivery room (DR) management of very low birth weight infants (VLBWI, <1500g) at birth, despite regularly updated international guidelines.

Atypical presentation of a hormonally active adrenocortical tumor in an adolescent leading to delayed diagnosis

Adrenocortical tumors are rare in children and present with variable signs depending on the type of hormone excess. We herein describe the unusual presentation of a child with adrenocortical tumor and introduce the concept of in vitro chemosensitivity testing. CASE REPORT: A 10.5-year-old girl presented with hypertrichosis/hirsutism and weight loss. The weight loss and behavioral problems, associated with halted puberty and growth, led to the initial diagnosis of anorexia nervosa. However, subsequent weight gain but persisting arrest in growth and puberty and the appearance of central fat distribution prompted further evaluation. RESULTS AND FOLLOW-UP: 24h-urine free cortisol was elevated. Morning plasma ACTH was undetectable, while cortisol was elevated and circadian rhythmicity was absent. Thus a hormonally active adrenal cortical tumor (ACT) was suspected. On magnetic resonance imaging (MRI) a unilateral, encapsulated tumor was found which was subsequently removed surgically. Tissue was investigated histologically and for chemosensitivity in primary cell cultures. Although there were some risk factors for malignancy, the tumor was found to be a typical adenoma. Despite this histology, tumor cells survived in culture and were sensitive to cisplatin in combination with gemcitabine or paclitaxel. At surgery, the patient was started on hydrocortisone replacement which was unsuccessfully tapered over 3 months. Full recovery of the hypothalamus-pituitary-adrenal axis occurred only after 3 years. CONCLUSIONS: The diagnosis of a hormonally active adrenocortical tumor is often delayed because of atypical presentation. Cortisol replacement following unilateral tumor excision is mandatory and may be required for months or years. Individualized chemosensitivity studies carried out on primary cultures established from the tumor tissue itself may provide a tool in evaluating the effectiveness of chemotherapeutic drugs in the event that the adrenocortical tumor may prove to be carcinoma.

[Laparoscopic management of genital prolapse by lateral suspension using mesh: a series of 377 patients]

Genital prolapse is frequent and can be found in about 50% of parous women. Its etiology is complex and multifactorial. Predisposing factors include: genetics (connective tissue disorders, family history); general state (age, parity, weight, smoking, obstructive pulmonary disease); trauma (carrying heavy loads, intense physical exercise); or iatrogenic (post hysterectomy). Treatment can be conservative or surgical and depends mainly on the severity of symptoms. Developments in surgical techniques and synthetic material in the last 20 years enabled us to use minimally invasive procedures with improved post operative course and decreased recurrence rates.

Effects of Aerobic Versus Resistance Exercise Without Caloric Restriction on Abdominal Fat, Intrahepatic Lipid, and Insulin Sensitivity in Obese Adolescent Boys: A Randomized, Controlled Trial

The optimal exercise modality for reductions of abdominal obesity and risk factors for type 2 diabetes in youth is unknown. We examined the effects of aerobic exercise (AE) versus resistance exercise (RE) without caloric restriction on abdominal adiposity, ectopic fat, and insulin sensitivity and secretion in youth. Forty-five obese adolescent boys were randomly assigned to one of three 3-month interventions: AE, RE, or a nonexercising control. Abdominal fat was assessed by magnetic resonance imaging, and intrahepatic lipid and intramyocellular lipid were assessed by proton magnetic resonance spectroscopy. Insulin sensitivity and secretion were evaluated by a 3-h hyperinsulinemic-euglycemic clamp and a 2-h hyperglycemic clamp. Both AE and RE prevented the significant weight gain that was observed in controls. Compared with controls, significant reductions in total and visceral fat and intrahepatic lipid were observed in both exercise groups. Compared with controls, a significant improvement in insulin sensitivity (27%) was observed in the RE group. Collapsed across groups, changes in visceral fat were associated with changes in intrahepatic lipid (r = 0.72) and insulin sensitivity (r = -0.47). Both AE and RE alone are effective for reducing abdominal fat and intrahepatic lipid in obese adolescent boys. RE but not AE is also associated with significant improvements in insulin sensitivity.

Patients with biallelic mutations in the chloride channel gene CLCNKB: long-term management and outcome

BACKGROUND: Little information on the management and long-term follow-up of patients with biallelic mutations in the chloride channel gene CLCNKB is available. METHODS: Long-term follow-up was evaluated from 5.0 to 24 years (median, 14 years) after diagnosis in 13 patients with homozygous (n = 10) or compound heterozygous (n = 3) mutations. RESULTS: Medical treatment at last follow-up control included supplementation with potassium in 12 patients and sodium in 2 patients and medical treatment with indomethacin in 9 patients. At the end of follow-up, body height was 2.0 standard deviation score or less in 6 patients; 2 of these patients had growth hormone deficiency. Body weight (

The effect of nutritional management on the mood of malnourished patients

Starvation and weight loss are common accompaniments of severe illness. The functional consequences of such malnutrition include not only physical changes but also psychological changes such as depression, anxiety, irritability, apathy, poor sleep pattern and loss of concentration. We carried out a pilot observational study in 22 undernourished patients at the time of referral to the nutritional team and after 8 days of nutritional support, using the Profile of Mood States Score (POMS) questionnaire to determine whether measurable and clinically significant changes in mood occurred with treatment.

Surgical management of gynecomastia--a 10-year analysis

BACKGROUND: Gynecomastia is defined as the benign enlargement of the male breast. Most studies on surgical treatment of gynecomastia show only small series and lack histopathology results. The aim of this study was to analyze the surgical approach in the treatment of gynecomastia and the related outcome over a 10-year period. PATIENTS AND METHODS: All patients undergoing surgical gynecomastia corrections in our department between 1996 and 2006 were included for retrospective evaluation. The data were analyzed for etiology, stage of gynecomastia, surgical technique, complications, risk factors, and histological results. RESULTS: A total of 100 patients with 160 operations were included. Techniques included subcutaneous mastectomy alone or with additional hand-assisted liposuction, isolated liposuction, and formal breast reduction. Atypical histological findings were found in 3% of the patients (spindle-cell hemangioendothelioma, papilloma). The surgical revision rate among all patients was 7%. Body mass index and a weight of the resected specimen higher than 40 g were identified as significant risk factors for complications (p < 0.05). CONCLUSIONS: The treatment of gynecomastia requires an individualized approach. Caution must be taken in performing large resections, which are associated with increased complication rates. Histological tissue analysis should be routinely performed in all true gynecomastia corrections, because histological results may reveal atypical cellular pathology.

Neonatal procedural pain exposure and pain management in ventilated preterm infants during the first 14 days of life

OBJECTIVES: Ventilated preterm infants are at high risk for procedural pain exposure. In Switzerland there is a lack of knowledge about the pain management in this highly vulnerable patient population. The aims of this study were to describe the type and frequency of procedures and to determine the amount of analgesia given to this patient group in two Swiss neonatal intensive care units. METHOD: A retrospective cohort study was performed examining procedural exposure and pain management of a convenience sample of 120 ventilated preterm infants (mean age = 29.7 weeks of gestation) during the first 14 days of life after delivery and born between May 1st 2004 and March 31st 2006. RESULTS: The total number of procedures all the infants underwent was 38,626 indicating a mean of 22.9 general procedures performed per child and day. Overall, 75.6% of these procedures are considered to be painful. The most frequently performed procedure is manipulation on the CPAP prongs. Pain measurements were performed four to seven times per day. In all, 99.2% of the infants received either non-pharmacological and/or pharmacological agents and 70.8% received orally administered glucose as pre-emptive analgesia. Morphine was the most commonly used pharmacological agent. DISCUSSION: The number of procedures ventilated preterm infants are exposed to is disconcerting. Iatrogenic pain is a serious problem, particularly in preterm infants of low gestational age. The fact that nurses assessed pain on average four to seven times daily per infant indicates a commitment to exploring a painful state in a highly vulnerable patient population. In general, pharmacological pain management and the administration of oral glucose as a non-pharmacological pain relieving intervention appear to be adequate, but there may be deficiencies, particularly for extremely low birth weight infants born <28 weeks of gestation.

Management of chronic pancreatitis

Chronic pancreatitis (CP) is an inflammatory disorder that results in permanent impairment of the glandular anatomy of the pancreas with or without functional abnormalities. The pathogenesis of CP is usually unclear, except in the case of alcohol-induced disease. The most common symptoms of CP are abdominal pain, diarrhea, and weight loss often requiring recurring hospitalization. Over time, pancreatic endocrine and exocrine dysfunction may develop as the disease progresses, and a variety of complications can occur. Among the possible complications are nutrient malabsorption and diabetes mellitus. The treatment of CP is difficult and challenging for every physician. Relieving pain is the first step in treating CP. This symptom needs to be controlled, often with narcotics, which can cause dependence. Diarrhea usually indicates the presence of steatorrhea, which is often treated with a high-calorie, high-protein, and low-fat diet to minimize symptoms of the underlying disease and to promote weight retention or gain. Pancreatic replacement therapy is used to combat maldigestion and malabsorption. Patients with diabetes may need insulin therapy for glycemic control. The use of parenteral nutrition for bowel rest is a standard approach in patients with symptomatic CP. The use of jejunal enteral feeding recently has been evaluated for efficacy in CP patients. The role of pancreatic endotherapy in the management of CP is evolving. Several reports have suggested that endoscopic therapy aimed at decompressing the obstructed pancreatic duct can be associated with pain relief in some patients. Surgery should be considered in patients who fail medical therapy.

Aerobic exercise but not resistance exercise reduces intrahepatic lipid content and visceral fat and improves insulin sensitivity in obese adolescent girls: a randomized controlled trial

It is unclear whether regular exercise alone (no caloric restriction) is a useful strategy to reduce adiposity and obesity-related metabolic risk factors in obese girls. We examined the effects of aerobic (AE) vs. resistance exercise (RE) alone on visceral adipose tissue (VAT), intrahepatic lipid, and insulin sensitivity in obese girls. Forty-four obese adolescent girls (BMI ≥95th percentile, 12-18 yr) with abdominal obesity (waist circumference 106.5 ± 11.1 cm) were randomized to 3 mo of 180 min/wk AE (n = 16) or RE (n = 16) or a nonexercising control group (n = 12). Total fat and VAT were assessed by MRI and intrahepatic lipid by proton magnetic resonance spectroscopy. Intermuscular AT (IMAT) was measured by CT. Insulin sensitivity was evaluated by a 3-h hyperinsulinemic (80 mU·m(2)·min(-1)) euglycemic clamp. Compared with controls (0.13 ± 1.10 kg), body weight did not change (P > 0.1) in the AE (-1.31 ± 1.43 kg) and RE (-0.31 ± 1.38 kg) groups. Despite the absence of weight loss, total body fat (%) and IMAT decreased (P < 0.05) in both exercise groups compared with control. Compared with control, significant (P < 0.05) reductions in VAT (Δ-15.68 ± 7.64 cm(2)) and intrahepatic lipid (Δ-1.70 ± 0.74%) and improvement in insulin sensitivity (Δ0.92 ± 0.27 mg·kg(-1)·min(-1) per μU/ml) were observed in the AE group but not the RE group. Improvements in insulin sensitivity in the AE group were associated with the reductions in total AT mass (r = -0.65, P = 0.02). In obese adolescent girls, AE but not RE is effective in reducing liver fat and visceral adiposity and improving insulin sensitivity independent of weight loss or calorie restriction.

Safe refeeding management of anorexia nervosa inpatients: an evidence-based protocol.

OBJECTIVE Anorexia nervosa is associated with several serious medical complications related to malnutrition, severe weight loss, and low levels of micronutrients. The refeeding phase of these high-risk patients bears a further threat to health and potentially fatal complications. The objective of this study was to examine complications due to refeeding of patients with anorexia nervosa, as well as their mortality rate after the implementation of guidelines from the European Society of Clinical Nutrition and Metabolism. METHODS We analyzed retrospective, observational data of a consecutive, unselected anorexia nervosa cohort during a 5-y period. The sample consisted of 65 inpatients, 14 were admitted more than once within the study period, resulting in 86 analyzed cases. RESULTS Minor complications associated with refeeding during the first 10 d (replenishing phase) were recorded in nine cases (10.5%), four with transient pretibial edemas and three with organ dysfunction. In two cases, a severe hypokalemia occurred. During the observational phase of 30 d, 16 minor complications occurred in 14 cases (16.3%). Six infectious and 10 non-infectious complications occurred. None of the patients with anorexia nervosa died within a follow-up period of 3 mo. CONCLUSIONS Our data demonstrate that the seriousness and rate of complications during the replenishment phase in this high-risk population can be kept to a minimum. The findings indicate that evidence-based refeeding regimens, such as our guidelines are able to reduce complications and prevent mortality. Despite anorexia nervosa, our sample were affected by serious comorbidities, no case met the full diagnostic criteria for refeeding syndrome.

Factors influencing the accuracy of fetal weight estimation with a focus on preterm birth at the limit of viability: a systematic literature review

BACKGROUND Fetal weight estimation (FWE) is an important factor for clinical management decisions, especially in imminent preterm birth at the limit of viability between 23(0/7) and 26(0/7) weeks of gestation. It is crucial to detect and eliminate factors that have a negative impact on the accuracy of FWE. DATA SOURCES In this systematic literature review, we investigated 14 factors that may influence the accuracy of FWE, in particular in preterm neonates born at the limit of viability. RESULTS We found that gestational age, maternal body mass index, amniotic fluid index and ruptured membranes, presentation of the fetus, location of the placenta and the presence of multiple fetuses do not seem to have an impact on FWE accuracy. The influence of the examiner's grade of experience and that of fetal gender were discussed controversially. Fetal weight, time interval between estimation and delivery and the use of different formulas seem to have an evident effect on FWE accuracy. No results were obtained on the impact of active labor. DISCUSSION This review reveals that only few studies investigated factors possibly influencing the accuracy of FWE in preterm neonates at the limit of viability. Further research in this specific age group on potential confounding factors is needed.

Management of Home Parenteral Nutrition: A Prospective Multicenter Observational Study

BACKGROUND There are no specific Swiss home parenteral nutrition (HPN) data showing patient characteristics, quality of life (QoL) and complications. The goal of this study was to collect representative nationwide data on current adult HPN patients in Switzerland for international comparability and benchmarking. METHODS This was a multicenter, nationwide, observational study. We conducted interviews for demographics, PN characteristics, QoL and complications. The data were assessed at baseline and after a follow-up of 3 months using a questionnaire. RESULTS Thirty-three adult patients were included. The most common underlying diseases were cancer, radiation enteritis and state after bariatric surgery, and the most prevalent indication was short bowel syndrome. During the 3-month observation period, significant increase or stabilization of body weight occurred in the patients, physical activity scores improved from 34.0 to 39.4 and mental scores improved from 41.9 to 46.4. HPN dependency and traveling restrictions were of the greatest concern. Diarrhea, xerostomia and/or thirst were frequent complaints. CONCLUSION Anthropometric parameters and QoL improved during the observational period in this HPN cohort. These Swiss HPN data are prerequisite for evaluation and comparison of HPN recommendations and best clinical practice, status of professional care instructions related to HPN effectiveness, quality of treatment and patient safety.

Anticoagulation Management Practices and Outcomes in Elderly Patients with Acute Venous Thromboembolism: A Clinical Research Study.

Whether anticoagulation management practices are associated with improved outcomes in elderly patients with acute venous thromboembolism (VTE) is uncertain. Thus, we aimed to examine whether practices recommended by the American College of Chest Physicians guidelines are associated with outcomes in elderly patients with VTE. We studied 991 patients aged ≥65 years with acute VTE in a Swiss prospective multicenter cohort study and assessed the adherence to four management practices: parenteral anticoagulation ≥5 days, INR ≥2.0 for ≥24 hours before stopping parenteral anticoagulation, early start with vitamin K antagonists (VKA) ≤24 hours of VTE diagnosis, and the use of low-molecular-weight heparin (LMWH) or fondaparinux. The outcomes were all-cause mortality, VTE recurrence, and major bleeding at 6 months, and the length of hospital stay (LOS). We used Cox regression and lognormal survival models, adjusting for patient characteristics. Overall, 9% of patients died, 3% had VTE recurrence, and 7% major bleeding. Early start with VKA was associated with a lower risk of major bleeding (adjusted hazard ratio 0.37, 95% CI 0.20-0.71). Early start with VKA (adjusted time ratio [TR] 0.77, 95% CI 0.69-0.86) and use of LMWH/fondaparinux (adjusted TR 0.87, 95% CI 0.78-0.97) were associated with a shorter LOS. An INR ≥2.0 for ≥24 hours before stopping parenteral anticoagulants was associated with a longer LOS (adjusted TR 1.2, 95% CI 1.08-1.33). In elderly patients with VTE, the adherence to recommended anticoagulation management practices showed mixed results. In conclusion, only early start with VKA and use of parenteral LMWH/fondaparinux were associated with better outcomes.
