Acute appendicitis stands as a prevalent cause necessitating surgical intervention globally, predominantly affecting young adults and children, with notably lower incidence among the elderly. Timely diagnosis facilitates effective management, mitigating the risk of severe complications. In this report, we present the case of a 59-year-old patient whose delayed diagnosis and consequently delayed surgical treatment led to serious complications. After the appendectomy, the patient, due to developing sepsis, was transferred to the intensive care unit. On the seventh postoperative day, complications were found in the form of wound dehiscence along with perforation of the jejunum. The second surgery involved a classic laparotomy, encompassing partial resection of the small intestine, and the creation of a single-barrel ileostomy. Further conservative treatment was implemented, and drainage of the abscess was performed. After treatment in the ICU, the patient was transferred to the surgical ward for further treatment. During the hospital stay, further conservative treatment was implemented, resulting in the improvement of the patient's general condition and resolution of symptoms. The patient was discharged home in optimal general condition with recommendations. After six months, the patient was brought to the surgical ward for reconstructive surgery to reestablish gastrointestinal continuity, which was carried out successfully.

Alzheimer's disease (AD) not only affects cognition and neuropathology, but several other facets capable of negatively impacting quality of life and potentially driving impairments, including altered gut microbiome (GMB) composition and metabolism. Aged (20 + mo) female TgF344-AD and wildtype rats were cognitively characterized on several tasks incorporating several cognitive domains, including task acquisition, object recognition memory, anxiety-like behaviors, and spatial navigation. Additionally, metabolic phenotyping, GMB sequencing throughout the intestinal tract (duodenum, jejunum, ileum, colon, and feces), neuropathological burden assessment and marker gene functional abundance predictions (PICRUSt2) were conducted. TgF344-AD rats demonstrated significant cognitive impairment in multiple domains, as well as regionally specific GMB dysbiosis. Relationships between peripheral factors were investigated using Canonical Correspondence Analysis (CCA), revealing correlations between GMB changes and both cognitive and metabolic factors. Moreover, communities of gut microbes contributing to essential metabolic pathways were significantly altered in TgF344-AD rats. These data indicate dysbiosis may affect cognitive outcomes in AD through alterations in metabolism-related enzymatic pathways that are necessary for proper brain function. Moreover, these changes were mostly observed in intestinal segments required for carbohydrate digestion, not fecal samples. These data support the targeting of intestinal and microbiome health for the treatment of AD.

Aflatoxin B1 (AFB1) is a prevalent mycotoxin present in feed ingredients. In this study, we investigated the effects of Lactobacillus salivarius (L. salivarius) on the Landes geese exposed to AFB1. The 300 one-day-old Landes geese were randomly divided into five groups: The control group received a basic diet, while the other groups were fed a basic diet supplemented with 10 μg/kg AFB1, 10 μg/kg AFB1+ 4*10 cfu/g L. salivarius, 50 μg/kg AFB1, and 50 μg/kg AFB1 + 4*10 cfu/g L. salivarius for 63 d. Results showed that high level AFB1 exposure significantly decreased final BW and ADG, increased feed/gain ratio (F/G) and liver index (P < 0.05). L. salivarius improved levels of IL-1, IL-6, and IL-12 under low level of AFB1 exposure (P < 0.05), along with similar trends observed in serum IgA, IgG, IgM, T3, T4, TNF-ɑ, and EDT (P < 0.05). AFB1 exposure reduced jejunum villus high and villus high/crypt depth ratio, and suppressed expression of ZO-1, Occludin, and Claudin-1 mRNA, and significant improved with L. salivarius supplementation under low level AFB1 exposure (P < 0.05). AFB1 significantly increased expression levels of TLR3 and NF-kB1, with supplementation of L. salivarius showing significant improvement under low AFB1 exposure (P < 0.05). Cecal microbiota sequencing revealed that under low level AFB1 exposure, supplementation with L. salivarius increased the abundance of Bacteroidetes and Lactococcus. In summary, supplementation with 4*10 cfu/g L. salivarius under 10 μg/kg AFB1 exposure improved growth performance and immune capacity, enhanced jejunum morphology, reduced liver inflammation, altered the cecal microbial structure, and positively affected the growth and development of geese.

Endoplasmic reticulum stress (ERS) and oxidative stress (OS) are adaptive responses of the body to stressor stimulation. Although it has been verified that Trichinella spiralis (T. spiralis) can induce ERS and OS in the host, their association is still unclear. Therefore, this study explored whether T. spiralis-secreted serpin-type serine protease inhibitor (TsAdSPI) is involved in regulating the relationship between ERS and OS in the host intestine. In this study, mice jejunum and porcine small intestinal epithelial cells (IECs) were detected using qPCR, western blotting, immunohistochemistry (IHC), immunofluorescence (IF), and detection kits. The results showed that ERS- and OS-related indexes changed significantly after TsAdSPI stimulation, and Bip was located in IECs, indicating that TsAdSPI could induce ERS and OS in IECs. After the use of an ERS inhibitor, OS-related indexes were inhibited, suggesting that TsAdSPI-induced OS depends on ERS. When the three ERS signalling pathways, ATF6, IRE1, and PERK, were sequentially suppressed, OS was only regulated by the PERK pathway, and the PERK-eif2α-CHOP-ERO1α axis played a key role. Similarly, the expression of ERS-related indexes and the level of intracellular Ca were inhibited after adding the OS inhibitor, and the expression of ERS-related indexes decreased significantly after inhibiting calcium transfer. This finding indicated that TsAdSPI-induced OS could affect ERS by promoting Ca efflux from the endoplasmic reticulum. The detection of the ERS and OS sequences revealed that OS occurred before ERS. Finally, changes in apoptosis-related indexes were detected, and the results indicated that TsAdSPI-induced ERS and OS could regulate IEC apoptosis. In conclusion, TsAdSPI induced OS after entering IECs, OS promoted ERS by enhancing Ca efflux, and ERS subsequently strengthened OS by activating the PERK-eif2α-CHOP-ERO1α axis. ERS and OS induced by TsAdSPI synergistically promoted IEC apoptosis. This study provides a foundation for exploring the invasion mechanism of T. spiralis and the pathogenesis of host intestinal dysfunction after invasion.

This study investigated marula seed cake (MSC) as alternative protein source (APS) replacing soyabean meal (SBM) in indigenous chicken diets. Four hundred, 3-week-old Boschveld chicks were randomly allocated to 5 iso-energetic-nitrogenous maize and SBM-based grower diets with 0, 10, 15, 20, and 25 % MSC, each with 5 replicate pens of 16 birds, in a completely randomised design (CRD), for 9 weeks. Results showed that dietary MSC quadratically decreased bird overall feed intake (FI) ( < 0.001) and body weight gain (BWG) ( < 0.01) as it linearly decreased the weights of hot carcass (HCW; < 0.05), spleen ( < 0.05), jejunum ( < 0.05), ileum ( < 0.001), and caecum ( < 0.001). In contrast, MSC increased chicken serum glucose ( < 0.05), cholesterol ( = 0.001) and phosphate ( < 0.05) as it decreased its amylase activity ( < 0.01). Also, it decreased bird meat lightness at 45 min ( < 0.05) and its yellowness at 45 min ( < 0.001) and 24 h ( < 0.001) whilst it increased its redness at 45 min ( < 0.01) and 24 h ( < 0.05) post-slaughter. In addition, MSC decreased chicken bone medial diaphysis ( < 0.05) as it induced no effects ( > 0.05) on overall feed conversion efficiency (FCE) and all other parameters. In conclusion, feeding of ≤ 15 % dietary MSC is nutritionally safe for indigenous chickens whilst detrimental on bird appetite, growth and meat yield, however without significantly affecting their physiology, at higher inclusion levels.

Food passage following proximal gastrectomy with double-tract reconstruction and its effect on nutritional status in early gastric cancer: a prospective single-center cohort study.
PURPOSE
Laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) expectedly results in improved nutritional status and less body weight loss than conventional total gastrectomy in upper-third gastric cancer. This study aimed to investigate the food passage patterns following LPG-DTR and its effect on nutritional outcomes up to 1 year after surgery.
METHODS
This prospective cohort study recruited 10 patients with early gastric cancer scheduled for LPG-DTR. Nutritional indices and body composition were assessed every 3 months up to 12 months. Liquid and solid food transits were evaluated with fluoroscopic upper gastrointestinal study and radionuclide scintigraphy, respectively.
RESULTS
At 12 months, patients exhibited a body weight loss of 14.5% ± 3.6%. The main passage routes for liquid and solid foods differed, primarily via the interposed jejunum for liquids, whereas via both tracts for solids. The median half-life of solid food emptying from the remnant distal stomach was 105.1 minutes (range, 50.8-2,194.2 minutes), and duodenal passage of solid food was noted in 9 of 10 patients. Those with gastric half-emptying time >3 hours demonstrated greater weight loss (19.5% ± 1.4% 12.5% ± 1.1%, P = 0.024) and more pronounced reduction in serum albumin levels (-0.5 ± 0.3 g/dL 0.0 ± 0.2 g/dL, P = 0.024) after 12 months.
CONCLUSION
LPG-DTR demonstrated varying food passage patterns depending on the food contents and delayed solid food emptying from the remnant stomach was associated with more substantial weight loss.

BACKGROUND
Laparoscopic total gastrectomy plus lymph node dissection is an effective treatment method for patients with gastric cancer. With the development and popularization of laparoscopic techniques in recent years, surgeons have become more skilled in laparoscopic techniques. Totally laparoscopic total gastrectomy (TLTG) has been developed; however, digestive tract reconstruction remains difficult, especially with anastomosis of the esophagus and jejunum. Using the self-pulling and latter transection (SPLT) method combined with a linear stapler has effectively solved the problem of narrow space in esophagojejunostomy. Here, we examined the safety and effectiveness of the SPLT technique in TLTG compared with SPLT with traditional esophagojejunostomy overlap anastomosis.
METHODS
We retrospectively analyzed all patients with gastric cancer admitted to the Department of Gastrointestinal Surgery of the Second Affiliated Hospital of Fujian Medical University from September 2020 to September 2023. In total, 158 patients met the inclusion criteria and were included. Patients were grouped according to whether the lower esophagus was transected after self-pulling. Patient demographics, tumor characteristics, surgical conditions, and postoperative results between the two groups were statistically analyzed.
RESULTS
A total of 158 patients were included in the study. All patients underwent TLTG and completed intracavitary anastomosis. There were 70 cases (44%) in the SPLT-Overlap group and 88 cases (56%) in the traditional overlap group. There was no significant difference in demographic and oncological characteristics between the two groups. The operation time (P = 0.002) and esophageal jejunum anastomosis time (P<0.001) were significantly shorter in the SPLT-Overlap group compared with the traditional overlap group. The intraoperative blood loss of the SPLT-Overlap group was 80.29 ± 36.36 ml, and the intraoperative blood loss of the traditional overlap group was 101.40 ± 46.68 ml. The difference was statistically significant (P=0.003). The SPLT-Overlap group also achieved a higher upper cutting edge (P =0.03). There was no significant difference between the two groups in terms of the incision size, postoperative hospital stay, time to first flatus, time to first liquid intake, drainage tube removal time, and esophagojejunal anastomotic diameter. There were 15 and 19 cases of short-term postoperative complications in the SPLT-Overlap and traditional Overlap groups, respectively. All patients received R0 resection, and no secondary surgery or death occurred.
CONCLUSION
We applied SPLT to overlap anastomosis. Short-term, SPLT has good safety and feasibility in TLTG. It can effectively shorten the time of digestive tract reconstruction, simplify the reconstruction procedure, and make the digestive tract reconstruction simple and fast; at the same time, a safe cutting edge can be obtained.

In the first study, an in vitro culture system was developed to investigate the effects of carnosine on macrophage proinflammatory cytokine response using an established chicken macrophage cell line (CMC), gut integrity using a chicken intestinal epithelial cell line (IEC), muscle differentiation in quail muscle cells (QMCs) and primary chicken embryonic muscle cells (PMCs), and direct anti-parasitic effect against Eimeria maxima sporozoites. Cells to be tested were seeded in 24-well plates and treated with carnosine at 4 different concentrations (0.1, 1.0, and 10.0 µg). After 18 h of incubation, cells were harvested to measure gene expression of proinflammatory cytokines in CMC, tight junction (TJ) proteins in IECs, and muscle cell growth markers in QMCs and PMCs. In vivo trials were conducted to investigate the effect of dietary carnosine on disease parameters in broiler chickens challenged with E. maxima. One hundred and twenty male broiler chickens (0-day-old) were allocated into 4 treatment groups: 1) basal diet without infection (NC), 2) basal diet with E. maxima infection (PC), 3) carnosine at 10.0 mg/kg feed with PC (HCS), and 4) carnosine at 1.0 mg/kg feed with PC (LCS). All groups except NC were orally infected with E. maxima on d 14. Jejunal samples were collected for lesion scoring and jejunum gut tissues were used for transcriptomic analysis of cytokines and TJ proteins. In vitro, carnosine treatment significantly decreased IL-1β gene expression in CMC following LPS stimulation. In vivo feeding studies showed that dietary carnosine increased BW and ADG of chickens in E. maxima-infected groups and reduced the jejunal lesion score and fecal oocyst shedding in HCS group. Jejunal IL-1β, IL-8, and IFN-γ expression were suppressed in the HCS group compared to PC. The expression levels of claudin-1 and occludin in IECs were also increased in HCS following carnosine treatment. In conclusion, these findings highlight the beneficial effects of dietary carnosine supplementation on intestinal immune responses and gut barrier function in broiler chickens exposed to E. maxima infection.

INTRODUCTION AND IMPORTANCE
Buerger's disease is an uncommon segmental nonatherosclerotic vasculitis essentially affecting small to medium-sized arteries and veins of upper and lower extremities and can lead to limb amputation. Visceral vessel involvement is quite rare accounting for 2% of cases presenting with acute abdomen due to mesenteric ischemia. Moreover, isolated visceral involvement is even rare.
CASE PRESENTATION
A 42-year-old gentleman, a chronic smoker, presented with abdominal pain associated with nausea and vomiting and loose stool of 2 months duration. Magnetic resonance enterography revealed segmental circumferential wall thickening with stricture in the mid part of the jejunum with lymphadenopathy features of possible inflammatory bowel disease (Crohn's disease). Furthermore, intraoperative surgical findings were also suggestive of Crohn's disease. However, histologic findings were consistent with thromboangiitis obliterans.
DISCUSSION
Thromboangiitis obliterans can present with inflammatory vascular lesions without necrosis in the early stage to varying degrees of recanalisation, gangrene, and amputation in the late stage. It rarely involves the brain, heart, and abdominal viscera. The visceral involvement may be in the form of intestinal obstruction or mesenteric ischemia or can mimic Crohn's in a background of smoking.
CONCLUSION
This case report will help to learn more about the rarer intestinal presentation of intestinal Buerger's disease. It can present with features of bowel ischemia, obstruction or Crohn's. So, histology would play a pivotal role in differentiating the diagnostic dilemma.

Incorporation of beneficial microbes to enhance the nutritive value of non-traditional feed additives is presently being promoted as a cost-effective way of increasing animal performance. Therefore, this trial investigated the impact of the incorporation of Dialium bark meal treated with yeast (TS) into broiler diets on intestinal histology, growth, and blood characteristics. One hundred and eighty days old Ross 308 broiler chickens were assigned to three treatments with five replications of 12 birds in a complete randomized design. The treatments were designed as (TS0: control) which is the (starter and finisher) diets without TS additive; whereas the TS0.5 and TS1.0 diets have TS additive at 0.5 and 1.5 g kg, respectively. The feeding trial lasted for 56 days comprising (28 days each for starter and finisher phases). Feed intake, body weight gains (BWG), and feed conversion ratio (FCR) were determined at the end of the starter and finisher phases. Blood and intestinal histomorphological indices were determined at the end of the finisher phase. Results indicate that TS contains 8.15 % crude protein, 29.84 % crude fibre, and 11.61 % ash. In addition, starter broilers in the TS0.5 and TS1.0 groups gained less weight and had a higher feed intake than those in the TS0 group. Broilers (29-56 d) in the TS0.5 and TS1.0 groups recorded better ( < 0.05) final live weight (FLW), BWG, and FCR than those in the TS0 group. Feed intake responded linearly to increasing TS levels in the diet during the finisher production phase. Broilers in group TS1.0 tended ( < 0.05) to have higher haemoglobin concentration, packed cell volume, red blood cell count, mean corpuscular haemoglobin, and mean corpuscular haemoglobin concentration compared to those in group TS0. Conversely, there were no treatment effects (p > 0.05) on mean cell volume, white blood cells, lymphocytes, heterophils, and serum biochemical variables. Broilers on TS diets had significantly improved histoarchitecture of the jejunum in broilers. In conclusion, results suggest that Dialium bark meal treated (TS) with dried active yeast is high in fibre and ash, and its addition at 0.5 and 1.0 g kg feed improved body weight gain, feed conversion ratio, aspects of the blood characteristics and intestinal histomorphology of the jejunum of broilers at the finisher production phase. It is recommended that TS can be added to broiler finisher diet up to 1.0 g kg feed for best growth performance, intestinal histomorphological, and blood characteristics.
