GLIM criteria for the diagnosis of malnutrition - A consensus report from the global clinical nutrition community.

RATIONALE: This initiative is focused on building a global consensus around core diagnostic criteria for malnutrition in adults in clinical settings. METHODS: In January 2016, the Global Leadership Initiative on Malnutrition (GLIM) was convened by several of the major global clinical nutrition societies. GLIM appointed a core leadership committee and a supporting working group with representatives bringing additional global diversity and expertise. Empirical consensus was reached through a series of face-to-face meetings, telephone conferences, and e-mail communications. RESULTS: A two-step approach for the malnutrition diagnosis was selected, i.e., first screening to identify "at risk" status by the use of any validated screening tool, and second, assessment for diagnosis and grading the severity of malnutrition. The malnutrition criteria for consideration were retrieved from existing approaches for screening and assessment. Potential criteria were subjected to a ballot among the GLIM core and supporting working group members. The top five ranked criteria included three phenotypic criteria (weight loss, low body mass index, and reduced muscle mass) and two etiologic criteria (reduced food intake or assimilation, and inflammation or disease burden). To diagnose malnutrition at least one phenotypic criterion and one etiologic criterion should be present. Phenotypic metrics for grading severity as Stage 1 (moderate) and Stage 2 (severe) malnutrition are proposed. It is recommended that the etiologic criteria be used to guide intervention and anticipated outcomes. The recommended approach supports classification of malnutrition into four etiology-related diagnosis categories. CONCLUSION: A consensus scheme for diagnosing malnutrition in adults in clinical settings on a global scale is proposed. Next steps are to secure further collaboration and endorsements from leading nutrition professional societies, to identify overlaps with syndromes like cachexia and sarcopenia, and to promote dissemination, validation studies, and feedback. The diagnostic construct should be re-considered every 3-5 years.

Long-Term Outcomes of Intestinal and Multivisceral Transplantation at a Single Center in Argentina.

BACKGROUND: Intestinal failure (IF) patients received parenteral nutrition (PN) as the only available therapy until intestinal transplantation (ITx) evolved as an accepted treatment. The aim of this article is to report the long-term outcomes of a series of ITx performed in pediatric and adult patients at a single center 9 years after its creation. PATIENTS AND METHODS: This is a retrospective analysis of the ITx performed between May 2006 and January 2015. Diagnoses, pre-ITx mean time on PN, indications for ITx, time on the waiting list for types of ITx, mean total ischemia time, and warm ischemia time, time until PN discontinuation, incidence of acute and chronic rejection, and 5-year actuarial patient survival are reported. RESULTS: A total of 42 patients received ITx; 80% had short gut syndrome (SG); the mean time on PN was 1620 days. The main indication for ITx was lack of central venous access followed by intestinal failure-associated liver disease (IFALD) and catheter-related infectious complications. The mean time on the waiting list was 188 days (standard deviation, ±183 days). ITx were performed in 26 children and 14 adults. In all, 32 procedures were isolated ITx (IITX); 10 were multiorgan Tx (MOT; 3 combined, 7 multivisceral Tx (MVTx), 1 modified MVTx and 2 with kidney); 2 (4.7 %) were retransplantations: 1 IITx, 1 MVTx, and 5 including the right colon. Thirteen patients (31%) received abdominal rectus fascia. All procedures were performed by the same surgical team. Total ischemia time was 7:53 ± 2:04 hours, and warm ischemia time was 40.2 ± 10.5 minutes. The mean length of implanted intestine was 325 ± 63 cm. Bishop-Koop ileostomy was performed in 67% of cases. In all, 16 of 42 Tx required early reoperations. The overall mean follow-up time was 41 ± 35.6 months. The mean time to PN discontinuation after Tx was 68 days (P = .001). The total number of acute cellular rejection (ACR) episodes until the last follow-up was 83; the total number of grafts lost due to ACR was 4; and the total graft lost due to chronic rejection was 3. At the time of writing, the overall 5-year patient survival is 55% (65% for IITx vs 22% for MOT; P = .0001); 60% for pediatric recipients vs 47% for adults (P = NS); 64% when the indication for ITx was SG vs 25% for non-SG (P = .002). CONCLUSIONS: At this center, candidates with SG, in the absence of IFALD requiring IITx, showed the best long-term outcomes, independent of recipient age. A multidisciplinary approach is mandatory for the care of intestinal failure patients, to sustain a rehabilitation and transplantation program over time.

Case Report: Spleen-preserving Multivisceral Transplant for Peutz-Jeghers Syndrome.

CASE REPORT: A 24-year-old man diagnosed with Peutz-Jeghers syndrome as a child underwent multiple surgeries owing to intussusception. Pretransplant workup showed >150 polyps along the gastrointestinal (GI) tract, some of them with high-grade dysplasia. Despite having intestinal sufficiency, a modified multivisceral transplantation was offered. PROCEDURE: An 18-year-old donor was procured using University of Wisconsin solution. The recipient's surgery started with a midline incision. Mobilization of the right colon and the root of the mesentery was done to isolate the superior mesenteric artery. The same maneuver was done with the left and sigmoid colon. The common bile duct was then isolated and transected at the cystic duct level. The abdominal portion of the esophagus and the proximal stomach were isolated and divided at the gastroesophageal junction. After that, the pancreas was mobilized, preserving the spleen with the splenic vessels. The distal GI tract was transacted at the level of the proximal rectum. For engraftment, an arterial conduit was placed in the infrarenal aorta and anastomosed to the graft's aortic patch. End-to-side portal reconstruction was made at the level of the portal vein, allowing performing a duct-to-duct biliary reconstruction over a 5-Fr T-tube. A hand-sewn gastrogastric anastomosis and piloroplasty were performed; the distal anastomosis was done with circular staplers. A gastrojejunostomy and a loop ileostomy were the final steps of the procedure. RESULTS: The patient stayed in intensive care for 2 days and enteral feeds were started on day 7. Currently, 23 months after transplant he is alive with an excellent quality of life.

Evaluación de ingesta en pacientes con hepatopatías crónicas / Evaluation of ingestion in patients with chronic liver diseases

La malnutrición calórico-protéica (MCP) es frecuente entre los pacientes con hepatopatías crónicas (HC) estableciéndose hasta en un 80 por ciento. El problema es multifactorial, siendo la disminución de la ingesta una de las causas más relevantes. Objetivo: evaluar la ingesta calórico-protéica en pacientes con HC. Se evaluaron prospectivamente 60 pacientes (26 mujeres, 43,3 por ciento) con una edad media de 54,1 años, con los siguientes diagnósticos: cirrosis biliar primaria 11 (18,3 por ciento), cirrosis alcohólica 26 (46,3 por ciento), hepatopatías autoinmunes 12 (20 por ciento), cirrosis criptogenética 6 (10 por ciento), Budd-Chiari 1 (1,7 por ciento), Hemocromatosis 1 (1,7 por ciento), cirrosis viral 3 (5 por ciento). Se utilizó el recordatorio de 3 días para la recolección de datos de ingesta, la evaluación global subjetiva EGS) para evaluación nutricional y la clasificación de Child-Pugh para evaluar severidad de la hepatopatía...

Assessment of nutritional status in a population of recently hospitalized patients.

Malnutrition in the hospital is not a new or rare problem, however, it is often unrecognized. In order to determine the baseline nutritional characteristics of recently hospitalized patients, we assessed the nutritional status of all medical in-patients between April and December 1994 in a large hospital in the province of Buenos Aires. One hundred and seventy patients were derived from the Internal Medicine ward and 176 patients from the General Surgery ward. Surgery patients were younger (median: 46 years vs 58 years of the Medicine patients). Among Medicine patients, cardiovascular and respiratory afflictions were the most common (30%), while gastrointestinal disorders were more often seen in Surgical patients (71%). A weight loss of more than 10% (%WL) was found in 12% of the Medicine and Surgery patients and a body mass index (BMI) of less than 19 kg/m2 was observed in about 5% of both groups. Ten percent of the Medicine patients and 14% of the Surgery patients were overweight. A mid-upper arm muscle circumference (MUAMC) less than the fifth percentile was found in 11% of the Medicine patients but in only 3% of the Surgery patients. These results suggest that this population of recently hospitalized patients is at high-risk for medical complications. Therefore, early nutrition assessment and appropriate nutrition intervention are required to improve clinical outcome and help reduce the cost of health care.

Effects of the calcium antagonist tiapamil on pulmonary gas exchange in patients with chronic obstructive pulmonary disease who receive salbutamol.

Patients with chronic obstructive pulmonary disease (COPD) and cardiovascular diseases are frequently given combination therapy with a beta 2-agonist and a calcium antagonist. Each drug is known to increase ventilation-perfusion inequalities. It was our aim to define the effects of their combination on lung function and on pulmonary gas exchange in eight subjects with COPD but partially reversible airway obstruction. Sixty minutes after placebo or 450 mg tiapamil, subjects inhaled 0.2 mg salbutamol. There was no significant effect of tiapamil on specific airway conductance and the forced expiratory volume in 1 second before or after the inhalation of salbutamol. Blood was drawn 30, 55, 80, and 100 minutes after placebo or tiapamil dosing. After placebo the mean (+/- SD) arterial oxygen tension (Pao2) fell from 67.1 +/- 7.3 to 64.4 +/- 5.5 mm Hg and the mean alveolar-arterial oxygen tension difference (AaDo2) rose from 34.6 +/- 8.4 to 40.5 +/- 6.8 mm Hg. After tiapamil the mean Pao2 fell from 68.7 +/- 7.3 to 66.4 +/- 5.8 mm Hg and the mean AaDo2 rose from 35.1 +/- 6.8 to 38.7 +/- 7.4 mm Hg. The changes in Pao2 were not significant. The increase in AaDo2 after placebo was significant, but that after tiapamil was not. We conclude that the combination of the calcium antagonist tiapamil and the bronchodilator salbutamol is safe with respect to lung function in COPD. There is no evidence that tiapamil increases beta 2-agonist-induced impairment in pulmonary gas exchange.
