Perioperative oral nutritional supplements in normally or mildly undernourished geriatric patients submitted to surgery for hip fracture: A randomized clinical trial

BACKGROUND Oral nutritional supplements have been recommended after orthopedic surgery in geriatric patients. This has been shown to be effective even in normally nourished or mildly undernourished geriatric patients. Whether perioperative administration of these products is also effective and suitable is not known. METHODS Randomized, controlled, open, paralleled two-arms clinical trial, comparing energy-protein supplements (40 g of protein and 400 kcal per day), with no intervention in normally nourished or mildly undernourished patients. Outcomes were serum proteins, body mass index, postoperative complications among others. RESULTS 60 Elderly patients were included. Patients in the intervention group (n = 30) ingested 52.2 ± 12.1% of the prescribed supplements per day for 5.8 ± 1.8 days before surgery and until hospital discharge. There was a significant change in serum albumin at follow-up (F = 22.536, P < 0.001), and between the two groups (F = 5.763, P = 0.002), favouring the intervention. The same was observed for serum prealbumin (F = 6.654, P = 0.001 within subjects, F = 2.865, P = 0.045 for interaction). Logistic regression showed that only supplemented proteins per day (OR[95%CI] = 0.925[0.869-0.985]) were associated with less postoperative complications (R(2) = 0.323, χ(2) = 11.541, P = 0.003). CONCLUSION Perioperative supplements in geriatric patients with hip fracture submitted to surgery showed better recovery of plasma proteins. Higher daily protein intakes were associated with less postoperative complications.

Effects of Oral Nutritional Supplements in Normally Nourished or Mildly Undernourished Geriatric Patients After Surgery for Hip Fracture: A Randomized Clinical Trial

BACKGROUND Oral nutritional supplements have been recommended after orthopedic surgery in geriatric patients to reduce postoperative complications. However, tolerability of supplements could be a limitation, and their universal use is not supported by the heterogeneity of previous studies, especially in patients without malnutrition. METHODS This study is a randomized, controlled, open, parallel, 3-arm clinical trial comparing supplementation with protein powder dissolved in liquids to aim at 36 g of protein per day, energy and protein supplements to aim at 37.6 g of protein and 500 kcal per day, or no intervention in normally nourished or mildly undernourished patients. Outcomes were serum albumin, prealbumin, retinol-binding globulin, and body mass index, among others. Postoperative complications were also recorded. RESULTS Ninety patients aged 83.8 +/- 6.6 years were included. The mean ingested amount of supplements was 41.1% +/- 20.6% in the protein powder supplement group and 51.4% +/- 13.2% in the energy protein supplement group (t = 2.278, P = .027). Postoperative supplements had no effect on the nutrition status during in-hospital follow-up, as assessed by serum albumin (P = .251), prealbumin (P = .530), retinol-binding globulin (P = .552), or body mass index (P = .582). Multivariate analysis showed that length of hospital stay with an established complication until its resolution (beta = .230, P = .031), total hospital stay (beta = .450, P < .001), baseline body mass index (beta = .204, P = .045), and total daily ingested proteins per body weight (beta = .252, P = .018) were predictive variables on the change in serum albumin (R2 = 0.409, F = 11.246, P < .001). CONCLUSIONS Oral nutritional supplements in normally nourished or only mildly undernourished geriatric patients with hip fracture submitted to surgery may be of interest for patients with postoperative complications and long hospital stays.

Chronic Increase of Bone Turnover Markers After Biliopancreatic Diversion is Related to Secondary Hyperparathyroidism and Weight Loss. Relation with Bone Mineral Density

BackgroundBiliopancreatic diversion (BPD) is the most effective bariatric procedure. Around 70% of these patients have secondary hyperparathyroidism (SH) in the long term as a consequence of calcium and vitamin D malabsorption. This work was aimed to study the influence of SH on bone turnover and its relationship with bone mineral density (BMD).MethodsBone turnover markers were determined in 63 BPD patients and 34 morbidly obese controls. In the BPD group, we also studied the influence of age, loss of weight, common channel length, PTH, vitamin D, and serum calcium on bone turnover as well as its relation with BMD.ResultsBPD patients showed significantly higher PTH, osteocalcin, and β-CTx levels than controls. In the multivariate regression analysis, only PTH (β = 0.42; P = 0.0002), menopausal status (β = 0.31; P = 0.007) and the percentage of lost BMI (β = −0.24; P = 0.03) significantly predicted the osteocalcin level (R2 = 0.33; F = 9.56; P < 0.0001). Similarly, only PTH (β = 0.39; P = 0.0005), menopausal status (β = 0.37; P = 0.001) and the percentage of lost BMI (β = −0.23; P = 0.04) significantly predicted the β-CTx level (R2 = 0.33; F = 9.82; P < 0.0001). Osteocalcin and β-CTx levels correlated negatively with BMD at lumbar spine (r = −0.38, P = 0.002 and r = −0.30, P = 0.02, respectively).ConclusionsChronic SH and the loss of weight determine a high rate of bone turnover that is associated with decreasing BMD in BPD patients.

Prevalencia de casos psiquiátricos en pacientes con sobrepeso u obesidad atendidos en consultas externas de un centro hospitalario

BACKGROUND AND AIMS: It has been recently shown that psychiatric disorders are associated with obesity. However this association has not been studied in overweight/obese patients at a hospital setting in our country. PATIENTS AND METHODS: We have studied 333 consecutive patients who were referred to our hospital outpatient clinic with overweight or obesity. Individuals with prior diagnosis of psychiatric disease were excluded from the study. Well validated auto-administered questionnaires were employed to identify psychiatric cases (Goldberg Health Questionnaire, GHQ, with a cut-off point of 5/6) and eating disorders (Eating Disorders Inventory, EDI, bulimia subscales with a cut-off point of 6/7). RESULTS: The prevalence of pathologic results in the GHQ was 47.1%, and the prevalence of pathologic results in the EDI was 5.8%. There were no differences after subgroup analysis when patients were classified according to their grade of obesity, but women presented a higher prevalence of psychiatric cases than men (p < 0.001). Multivariate analysis showed an influence of female gender on the scores of the administered questionnaires (p < 0,01 in all of them) and of body mass index on the depression subscale of GHQ and on EDI (p < 0,001 in both). CONCLUSION: The prevalence of psychiatric cases in overweight/obese patients referred to a hospital setting is high, and higher in women than in men.

Influencia de la pérdida de peso en la evolución clínica, metabólica y psicológica de los pacientes con sobrepeso u obesidad

INTRODUCTION AND OBJECTIVE The clinical evolution and psychological well-being of patients with overweight or obesity is still a matter of controversy. The aim of this study is to know the impact of the loss of weight on the evolution of the alterations both clinical and metabolic as psychological in patients with overweight or obesity. PATIENTS AND METHOD We studied a cohort of 192 patients randomly chosen. All of them were characterized clinically and biochemically. Autoadministered questionnaires were used which were already validated in the Spanish population:the General Health Questionnaire (GHQ-28), and bulimia subescale, the Eating Disorder Inventary (EDI). For the statistical analysis using the statistical program SPSS 15.0. Data are expressed as mean (standard deviation). RESULTS The weight loss was 3.77 (4.85) kilograms, equivalent to a 3.8 (4.86)% of the total weight, the diameter of the waist was reduced by 3.78 (5.89) centimeters, systolic blood pressure was reduced by 3.36 (15.61) mmHg and diastolic in 2.15 (11.26) mmHg. We also found a decreased significantly of glucose levels 7.37(21.23) mg/dl, insulin levels 2.773 (8.749) IU/ml, HOMA-IR index 0.925 (2.728), triglycerides 12.59 (82.95) mg/dl and uric acid 0.172 (1.13) mg/dl. The basal score of the GHQ-28 was pathological in 44,8% of the studied patients, and after six months of treatment, it improved in 20,8% of the patients (p < 0,001). The EDI bulimia subscale score at the beginning of the treatment was 1,02 (SD 1,91), improving after six months of treatment to 0,65 (SD 1,49) p < 0,002. CONCLUSION The decrease in weight improves not only clinical parameters and biochemical cardiovascular risk and insulin resistance, but also improves the scale score Goldberg, with higher impact on those with worse baseline GHQ-28 scores.

Estimación del impacto económico y sanitario de las complicaciones de la diabetes mellitus tipo 2 en la Comunidad de Madrid

OBJECTIVE To estimate the economic and health impact of chronic complications (macrovascular and microvascular) of type 2 diabetes mellitus (T2DM) in the autonomous community of Madrid (Spain) (ACM). METHODS The number of expected complications was obtained from a descriptive, cross-sectional study on a cohort of 3,268 patients with T2DM from the ACM. Cost of complications (€, 2012) was assessed both at hospitals and in primary care. The number of medical visits in primary care and drug treatment for complications were collected by a panel of 21 physicians experienced in treatment of T2DM. Population and epidemiological data and healthcare costs were obtained from Spanish sources. Univariate sensitivity analyses were performed. RESULTS It is estimated that there are 390,944 patients with T2DM in the ACM, and that they experience 172,406 and 212,283 macrovascular and microvascular complications respectively during their lifetimes. Mean cost of T2DM complications per patient is estimated at € 4,121.54 (66% due to macrovascular complications). The economic impact of T2DM complications in the ACM would be € 1,611 million (1,065 and 545 millions from macrovascular and microvascular complications respectively). The economic impact would range from € 1,249 and 2.509 million euro depending on T2DM prevalence. CONCLUSIONS Complications of T2DM have a great health and economic impact in ACM.

Chylous ascytes secondary to acute pancreatitis: a case report and review of literature

Chylous ascites is an uncommon finding which is due to the presence of thoracic or intestinal lymph in the abdominal cavity. It is usually caused by a chronic disruption of the lymphatic system. The present report is one of the rare cases in the literature of chylous ascites secondary to idiopathic acute pancreatitis, which showed a complete resolution with a combination of low fat enteral nutrition with MCT and somatostatin analogs.

Metabolic control and chronic complications during a 3-year follow-up period in a cohort of type 2 diabetic patients attended in primary care in the Community of Madrid (Spain)

BACKGROUND Our aim was to analyze both metabolic control and chronic complications of type 2 diabetes mellitus (T2D) patients regularly attended in primary care during a 3 years of follow-up in the Community of Madrid (Spain). METHODS From 2007 to 2010 we prospectively included 3268 patients with T2D attended by 153 primary care physicians from 51 family health centers. An prospective cohort study with annual evaluation over 3 years to the same population was performed. We measured the goals of control in diabetic patients and the incidence of chronic complications of diabetes during the study period. RESULTS A significant decrease in serum glucose levels (143±42mg/dl vs 137±43mg/dl, p<0.00), HbA1c (7.09±1.2% vs 7.02±1.2%, p<0.00), total cholesterol (191.4±38mg/dl vs 181.5±36mg/dl, p<0.00), LDL cholesterol (114.7±31mg/dl vs 105.5±30mg/dl, p<0.00) and triglyceride levels (144.5±93mg/dl vs 138±84mg/dl, p<0.00) during study period was documented. On the contrary, a significant elevation in HDL cholesterol levels was observed (49.2±14mg/dl vs 49.9±16mg/dl, p<0.00). The incidence of diabetic complications throughout the study period was low, with a incidence of coronary heart disease of 6.2%, peripheral arterial disease 3%, ischemic stroke 2.8%, diabetic foot 11.2%, nephropathy 5.9%, retinopathy 4.5%, and neuropathy 3%. CONCLUSION Metabolic control in T2D patients attended in primary care in the Community of Madrid throughout 3 years is adequate and is accompanied by low percent of chronic diabetic complications during this period of follow-up.

Síndrome de intestino corto causa de hipomagnesemia: importancia de su diagnostico y tratamiento

The short bowel syndrome (SIC) is a complex entity characterized by a malabsorptive state usually secondary to extensive intestinal resection originating a clinical, metabolic and/or nutritional disorder due to the reduction of the effective intestinal absorptive surface. The diagnosis is essentially clinical and, due to the patients malabsorptive process, it requires nutritional support to maintain their basic requirements, as the case reported. The clinical features of SIC patients depend on the grade of the alteration of function of the the small intestine or the impairment secondary to the surgical resection. We know that electrolytes are absorbed predominantly in the proximal gut. The regulation of ion/mineral levels depend on both the intestinal absorption and the renal excretion. We present an unusual case of SIC with only low absorption of magnesium. We discuss the most outstanding aspects of the case and review the literature.

Insulin action in adipose tissue in type 1 diabetes

Background: Insulin action has been reported to be normal in type 1 diabetic patients. However, some studies have reported an insulin resistance state in these patients. The aim of this study was to investigate insulin resistance in a group of type 1 diabetic patients. We studied the insulin action in adipose tissue and analyzed the effects of duration of disease, body mass index (BMI), and glycosylated hemoglobin on insulin action at the receptor and postreceptor levels in adipocytes. Methods: Nine female type 1 diabetic patients with different durations of disease and eight nondiabetic female patients of comparable age and BMI were studied. 125I-insulin binding and U-[14C]-D-glucose transport was measured in a sample of subcutaneous gluteus adipose tissue obtained by open surgical biopsy from each subject. Results: The duration of disease was negatively correlated with both 125I-insulin binding capacity (r = −0.70, P < 0.05) and basal and maximum insulin-stimulated glucose transport (r = −0.87, P < 0.01, and r = −0.88, P < 0.01, respectively). Maximum specific 125I-insulin binding to the receptors in adipocytes was higher in the group of patients with a shorter duration of disease (P < 0.01). Basal and maximum insulin-stimulated glucose transport was significantly higher in the group with less than 5 years of disease (P < 0.01). No correlation was found between BMI and insulin action. Conclusion: Female type 1 diabetic patients have normal insulin action. There is a high glucose uptake in the early phase of the disease, although a longer duration of disease appears to be a contributing factor to a decrease in insulin action in these patients, and involving both receptor and postreceptor mechanisms.
