Immediate Oral Refeeding in Patients With Mild and Moderate Acute Pancreatitis: A Multicenter, Randomized Controlled Trial (PADI trial).

OBJECTIVE: To establish the optimal time to start oral refeeding in mild and moderate acute pancreatitis (AP) to reduce hospital length-of-stay (LOS) and complications. SUMMARY BACKGROUND DATA: Oral diet is essential in mild and moderate AP. The greatest benefits are obtained if refeeding starts early; however, the definition of "early" remains controversial. METHODS: This multicenter, randomized, controlled trial (NCT03829085) included patients with a diagnosis of mild or moderate AP admitted consecutively to 4 hospitals from 2017 to 2019. Patients were randomized into 2 treatment groups: immediate oral refeeding (IORF) and conventional oral refeeding (CORF). The IORF group (low-fat-solid diet initiated immediately after hospital admission) was compared to CORF group (progressive oral diet was restarted when clinical and laboratory parameters had improved) in terms of LOS (primary endpoint), pain relapse, diet intolerance, complications, and, hospital costs. RESULTS: One hundred and thirty one patients were included for randomization. The mean LOS for the IORF and CORF groups was 3.4 (SD ± 1.7) and 8.8 (SD ± 7.9) days, respectively (P < 0.001). In the CORF group alone, pain relapse rate was 16%. There were fewer complications (8% vs 26%) and health costs were twice as low, with a savings of 1325.7€/patient in the IORF than CORF group. CONCLUSIONS: IORF is safe and feasible in mild and moderate AP, resulting in significantly shorter LOS and cost savings, without causing adverse effects or complications.

Predictive Value of Gut Peptides in T2D Remission: Randomized Controlled Trial Comparing Metabolic Gastric Bypass, Sleeve Gastrectomy and Greater Curvature Plication.

BACKGROUND: Our aim was to determine the predictive value of gut hormone changes for the improvement of type 2 diabetes (T2D) following metabolic Roux-en-Y gastric bypass (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP) in a randomized controlled trial. Contradictory results have been obtained regarding the role of gastrointestinal hormones (in particular GLP-1) in beneficial metabolic bariatric surgery outcomes. METHODS: Forty-five patients with T2D (mean BMI 39.4 ± 1.9 kg/m2) were randomly assigned to mRYGB, SG, or GCP. Anthropometric and biochemical parameters, fasting concentrations of PYY, ghrelin, glucagon, and area under the curve (AUC) of GLP-1 after a standard meal test were determined prior to and at months 1 and 12 after surgery. RESULTS: Twelve months after surgery, total weight loss percentage was higher and HbA1c lower in the mRYGB group than in the SG and GCP groups (-35.2 ± 8.1 and 5.1 ± 0.6% vs. -27.8 ± 5.4 and 6.2 ± 0.8% vs. -20.5 ± 6.8 and 6.6 ± 1.3%; p = 0.007 and p < 0.001, respectively). Moreover, GLP-1 AUC at months 1 and 12 was greater and T2D remission was higher in mRYGB (80 vs. 53.3 vs. 20%, p < 0.001). Insulin treatment (odds ratio (OR) 0.025, p = 0.018) and the increase in GLP-1 AUC from baseline to month 1 (OR 1.021, p = 0.013) were associated with T2D remission. CONCLUSIONS: mRYGB achieves a superior rate of weight loss and T2D remission at month 12. Enhanced GLP-1 secretion 1 month after surgery was a determinant of glucose metabolism improvement.

Outcomes of colonic diverticulitis according to the reason of immunosuppression.

BACKGROUND: The aims of this study were to analyze the relationship between the different causes of immunosuppression (IMS) and diverticulitis. METHODS: IMS patients admitted for colonic diverticulitis were included in the study. Patients were divided in 5 groups according to the reasons of IMS: group I, chronic corticosteroid therapy; group II, transplant patients; group III, malignant neoplasm disease; group IV, chronic renal failure; group V, others immunosuppressant treatment. Rate of emergency surgery, outcomes in terms of postoperative mortality, and recurrence rate after nonoperative management were analyzed according to the reason of IMS. RESULTS: Emergency surgery was performed in 76 patients (39.3%). It was needed more frequently in group I. Overall, postoperative mortality was of 31.6% and recurrence rate after successful nonoperative management occurred in 30 patients (27.8%). No differences were observed among the groups. CONCLUSIONS: The rate of emergency surgery in IMS patients at the first episode of acute colonic diverticulitis is high. Elective surgery in IMS patients should be individually indicated according to persistence of symptoms or early recurrences.

Green hams electrical impedance spectroscopy (EIS) measures and pastiness prediction of dry cured hams.

The objective of this study was to assess the value of electrical impedance spectroscopy (EIS) as a predictor of certain dry-cured ham sensory properties in green hams of different technological meat qualities and processed commercially. Measurements of technological meat quality (weight, ham conformation, subcutaneous fat thickness, pH(45) and pH(u)) and some sensory properties (adhesiveness, hardness, crumbliness, pastiness, fibrousness and saltiness) were carried out on the Biceps femoris (BF) and Semimembranosus (SM) muscles. The electrical parameters, R(o), R(inf), ratio (R(inf)/R(o)), F(c) and α, were obtained with EIS equipment applied to two different regions of the ham at 36 h post mortem (BF and SM). Principal component (PC) analysis was used to describe the relationship between sensory properties and electrical parameters. For BF muscle there were no clear relationships between the electrical parameters and the sensory properties. However, for SM muscle, pastiness was correlated positively with the ratio and F(c) obtained by EIS. None of the electrical parameters obtained by EIS were able to differentiate between groups of hams classified according to their level of pastiness in the BF muscle. However, in the SM muscle, the origin of the pastiness was related to the use of PSE meat and was predicted by the electrical impedance measurements. The EIS prototype correctly detected 69.2 and 56.0% (for SM and BF muscles, respectively) of the problem hams in terms of pastiness. These results could be of use in the selection of the raw material to reduce the incidence of dry-cured hams with defective texture.
