Meta-Analysis Comparative Study
Isolated Roux-en-Y versus single loop pancreaticojejunal reconstruction after pancreaticoduodenectomy - a systematic review and meta-analysis of randomised controlled trials.
BACKGROUND
Pancreaticoduodenectomy is a complex intra-abdominal operation used for the treatment of benign and malignant disease of the pancreatic head or periampullary region. Despite developments in surgical techniques, pancreaticoduodenectomy is still associated with high rate of postoperative complications. We performed this systematic review and meta-analysis to compare the surgical outcomes of isolated Roux-en-Y pancreaticojejunostomy (IRYPJ), and conventional pancreaticojejunostomy(CPJ).
METHODS
We performed a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We searched the following electronic databases - PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Clinical-Trials.gov. Published trials comparing the efficacy and safety of IRYPJ and CPJ after pancreaticoduodenectomy were evaluated. The search terms were "pancreaticoduodenectomy," "Whipple," "pylorus-preserving pancreaticoduodenectomy," "pancreaticojejunostomy," "Roux-en-Y," and "isolated Roux loop pancreaticojejunostomy." Only randomised controlled trials comparing outcome of IRYPJ and CPJ after pancreaticoduodenectomy were included. The analysed outcome measures were postoperative pancreatic fistula (POPF), clinically relevant POPF (CR-POPF), bile leak and delayed gastric emptying (DGE).
RESULTS
The initial search yielded 342 results but only four randomised control trials fulfilled the inclusion criteria and were included for data synthesis and meta-analysis. Meta-analysis of POPF revealed that IRYPJ is associated with less POPF compared to CPJ but the difference was not statistically significant (risk ratio = 0.58, = 0.56). A similar finding was also observed with CR-POPF (risk ratio = 0.17, = 0.87) and DGE (risk ratio = 0.74, = 0.46).
CONCLUSION
Isolated Roux-en-Y pancreaticojejunostomy is not associated with a superior outcome when compared to CPJ.

The common belief that heat treatment enhances the gastric digestion of proteins is largely based on findings from animal proteins and may not apply to all proteins, particularly plant proteins. Here, we compared the digestion characteristics of soybean protein isolates (SPI) in an semi-dynamic digestion model and found distinct effects of heat treatment on the digestion properties of plant proteins. The results revealed that heat-treated SPIs formed clots during the early stages of digestion, although the clots gradually became smaller and looser as digestion progressed, the systems remained turbid at the end of gastric digestion, indicating the lag in their emptying. Furthermore, heat treatment altered the rheological properties of SPI, resulting in increased viscosity and slower gastric emptying. These effects became more pronounced with increasing heat treatment temperatures. The fluorescence spectrum analysis indicated that heat treatment altered its conformation. This led to protein unfolding and exposure of hydrophobic groups, facilitating the formation of larger aggregates during digestion. Additionally, heat treatment exposed more cleavage sites for gastric proteases, increasing the extent of hydrolysis. Elevated levels of free amino acids and a smaller molecular weight distribution further corroborated these findings. These findings contribute to a deeper understanding of the gastric digestion characteristics of plant proteins and the relationship between protein aggregation structure and the digestion process.

Review
Gastroparesis is a heterogeneous motility disorder characterized by nausea, vomiting, and postprandial fullness. Its diagnosis requires objective documentation of delayed gastric emptying of solid food and exclusion of mechanical obstruction. Its epidemiology is unclear, and the main causes are diabetes mellitus and idiopathic disease. Cardinal symptoms often co-occur. Management involves nutritional assessment, dietary changes, drug evaluation, glycemic control (for patients with diabetes mellitus), and symptom relief. In this review, we explore challenges nongastroenterologists may encounter and how they can use current recommendations to manage patients with gastroparesis.

INTRODUCTION
Depression affects an estimated 350 million people worldwide and is implicated in up to 60% of suicides. Only about 60-70% of patients respond to antidepressant therapy. One of the factors causing patients to not attain therapeutic goals is herb-drug interactions.
OBJECTIVE
To investigate any potential herb-drug interaction that might exist between extract (XAE) or xylopic acid (XA) and selected conventional antidepressants (imipramine, fluoxetine, and venlafaxine) in mice.
METHODS
Dried, powdered fruits of were cold macerated in 70% ethanol to obtain XAE. XA was isolated by cold macerating dried fruits of in petroleum ether, crystallising impure XA with ethyl acetate, and purifying XA crystals with 96% ethanol. Pharmacodynamic interaction was assessed via isobolographic analysis of tail suspension tests of the agents individually and in their respective combinations. Pharmacokinetic interaction was assessed by monitoring the effect of coadministrations on the plasma concentration of antidepressants and xylopic acid via HPLC analysis.
RESULTS
XAE and XA in mice showed significant antidepressant-like activity in the tail suspension test. With interaction indices less than one, synergism of antidepressant effect was observed in the extract/fluoxetine ( = 0.502), extract/imipramine ( = 0.322), extract/venlafaxine ( = 0.601), xylopic acid/imipramine ( = 0.556), xylopic acid/venlafaxine ( = 0.451), and xylopic acid/fluoxetine ( = 0.298) combinations, which may be potentially due to elevation of serotonergic neurotransmission via varying mechanisms. The AUC of imipramine (AUC = 1966 ± 58.98 g/ml.h) was significantly ( < 0.0001) reduced by extract (AUC = 1228 ± 67.40 g/ml.h) and xylopic acid (AUC = 1250 ± 55.95 g/ml.h), while the AUC of xylopic acid (AUC = 968.10 ± 61.22 g/ml.h) was significantly ( < 0.0001) reduced by venlafaxine (AUC = 285.90 ± 51.92 g/ml.h) and fluoxetine (AUC = 510.60 ± 44.74 g/ml.h), possibly due to the effect of interfering agents on gastric emptying hence reducing oral absorption.
CONCLUSION
extract and xylopic acid interacted synergistically with imipramine, fluoxetine, and venlafaxine and reduced the systemic circulation of imipramine.

Satiation is the physiologic process that regulates meal size and termination, and it is quantified by the calories consumed to reach satiation. Given its role in energy intake, changes in satiation contribute to obesity's pathogenesis. Our study employed a protocolized approach to study the components of food intake regulation including a standardized breakfast, a gastric emptying study, appetite sensation testing, and a satiation measurement by an test. These studies revealed that satiation is highly variable among individuals, and while baseline characteristics, anthropometrics, body composition and hormones, contribute to this variability, these factors do not fully account for it. To address this gap, we explored the role of a germline polygenic risk score, which demonstrated a robust association with satiation. Furthermore, we developed a machine-learning-assisted gene risk score to predict satiation and leveraged this prediction to anticipate responses to anti-obesity medications. Our findings underscore the significance of satiation, its inherent variability, and the potential of a genetic risk score to forecast it, ultimately allowing us to predict responses to different anti-obesity interventions.

Impact of postoperative pancreatic fistula on outcomes in pancreatoduodenectomy: a comprehensive analysis of American College of Surgeons National Surgical Quality Improvement Program data.
BACKGROUND
Pancreatoduodenectomy (PD) is a major surgical procedure associated with significant risks, particularly postoperative pancreatic fistula (POPF). Studies have highlighted the importance of certain risk factors for POPF, which are crucial for surgical decision-making and the management of high-risk patients undergoing PD. This study aimed to assess the surgical outcomes of patients undergoing PD who met the International Study Group of Pancreatic Surgery - Class D (ISGPS-D) criteria.
METHODS
This study analyzed American College of Surgeons National Surgical Quality Improvement Program data (2014-2021) for patients undergoing ISGPS-D PD, classified as having a soft pancreatic texture and a pancreatic duct of ≤3 mm. This study focused on mortality rates and the correlation between several factors and POPF (ISGPS grade B/C).
RESULTS
From 5964 patients who underwent PD and met the ISGPS-D criteria, the 30-day mortality rate was 1.98%. Males had a higher incidence of POPF than females (57.42% vs 47.35%, respectively; P < .001). Patients with POPF experienced significantly higher rates of major postoperative complications (Clavien-Dindo grade ≥ IIIa), including thrombosis, pneumonia, sepsis, delayed gastric emptying, wound disruption, infections, and acute renal failure. There was a marked increase in the 30-day readmission and mortality rates in patients with POPF (30.0% vs 17.6% and 3.2% vs 1.4%, respectively; all P < .001). Multivariate analysis highlighted female sex as a protective factor against mortality (odds ratio [OR], 0.47; P < .001) and extended hospital stay (>10 days) as a predictor of increased mortality risk (OR, 2.37; P < .001).
CONCLUSION
This study underscored the significant association between POPF and increased postoperative morbidity and mortality rates. Future efforts should concentrate on refining surgical techniques and improving preoperative assessments to mitigate the risks associated with POPF in patients undergoing PD.

PURPOSE OF THE STUDY
The primary objective was to establish the reference values for small-bowel and colonic transit within the context of the routine standard solid meal gastric emptying scintigraphy (GES). The secondary objective was to compare the small-bowel and colonic transit between the anterior view and geometric mean methods.
MATERIALS AND METHODS
Twenty-nine healthy controls underwent routine GES, with additional imaging at 24 h if feasible. Small-bowel transit was assessed using the index of small-bowel transit (ISBT), calculated as the ratio of terminal ileal reservoir counts to total abdominal counts at 4 h. Colonic transit was evaluated using the colonic geometric center (CGC) by dividing the large bowel into four segments, with an additional fifth segment accounting for the eliminated counts. Reference values were established based on the fifth percentile or mean ± 1.96 standard deviations. Rapid small-bowel transit was visually determined. Paired Samples -test or Wilcoxon signed-rank test, as applicable, was used to compare the small-bowel and colonic transit between the anterior view and geometric mean methods. For comparing small-bowel and colonic transit between females and males, the Independent samples -test or Mann-Whitney -test was applied, as appropriate. The correlation between age and small-bowel and colonic transit was assessed using Spearman's rank correlation analysis.
RESULTS
The reference value for small-bowel transit using the geometric mean method was established as ISBT >37% at 4 h, whereas rapid small-bowel transit was defined as the first visualization of activity in the cecum-ascending colon within 2 h. For colonic transit, the reference range was established as CGC 2.8-4.4 at 24 h. Comparing the anterior view and geometric mean methods, there were no significant differences in ISBT and CGC values ( ≥ 0.125). Gender did not affect small-bowel and colonic transit in both methods ( ≥ 0.378), and age showed no significant correlations ( ≥ 0.053).
CONCLUSION
This study determined the reference values for small-bowel and colonic transit in the Indian population using routine GES, avoiding the need for additional complex procedures. The results may be generalized to the Indian population, emphasizing the importance of assessing small-bowel and colonic transit in patients with normal gastric emptying parameters to enhance gastrointestinal transit evaluation.

Semaglutide (Ozempic), a GLP-1 receptor agonist effective in weight management, and ziprasidone (Geodon), an antipsychotic with a lower risk of metabolic side effects, are well-established in treating type 2 diabetes and schizophrenia, respectively. However, their interactions and effects on psychiatric symptoms are less understood. In this study, we report a case of a 43-year-old male with schizophrenia and diabetes with exacerbated paranoid delusions upon semaglutide administration for weight loss; symptoms peaked at higher doses and subsided after dose reduction. Concurrently, serum ziprasidone levels were significantly elevated at the dose reduction, suggesting a pharmacokinetic interaction likely due to semaglutide-induced slowed gastric emptying affecting ziprasidone's absorption and metabolism. This study illustrates the need for careful monitoring of psychiatric symptoms and drug levels when these medications are used together. Additionally, further research into their interactions to optimize treatment for patients with coexisting metabolic and psychiatric conditions is warranted.

BACKGROUND
Absent "organic" disease, dyspeptic symptoms may arise from abnormal gastric sensation, accommodation, motility or emptying (GE). Extensive gastric sensorimotor evaluation is rarely undertaken because testing is prolonged, invasive, poorly tolerated or unavailable.
AIMS
To investigate whether gastric antral motor function, evaluated with scintigraphy, predicts GE. To explore whether motor testing with symptom recording predicts day-to-day symptoms in patients with dyspepsia.
METHODS
GE was determined using a scintigraphic solid-meal protocol (296 kcal, 35% fat). Antral motility was estimated from 10 min of scintigraphic time-activity curves acquired 40 min after meal consumption. An antral motility index (MI) was derived from contraction amplitude and frequency. Intra-gastric distribution of the meal on scintograms at 1 h (IGD1) was determined. Meal-induced symptoms were evaluated by questionnaire. Patients completed the Gastroparesis Cardinal Symptom Index Daily Diary (GCSI-DD) for 14 days.
RESULTS
Twelve healthy participants and 23 prospectively recruited patients completed the study. Nine patients had delayed, and 2 had rapid, GE. In univariate analysis MI explained 42% of GE half-time. In multivariate analysis MI and GE half-time explained 25% of the variance in meal-induced symptoms. While scintigraphic evaluation of gastric motor function with symptom recording explained 80% of the variance in the GCSI-DD, meal-induced symptoms were the only significant predictor. However, among patients with delayed GE, MI, GE half-time, IGD1, and meal-induced symptoms all significantly predicted GCSI-DD.
CONCLUSIONS
Antral motility predicts GE. In exploratory analyses, only meal-induced symptoms predicted daily symptoms among patients with dyspepsia. However, motor function also predicted symptoms in patients with delayed GE.
