Recent advances have highlighted the gut microbiota as a significant contributor to the development and progression of atherosclerosis, which is an inflammatory cardiovascular disease (CVD) characterized by plaque buildup within arterial walls. The gut microbiota, consisting of a diverse collection of microorganisms, impacts the host’s metabolism, immune responses, and lipid processing, all of which contribute to atherosclerosis. This review explores the complex mechanisms through which gut dysbiosis promotes atherogenesis. We emphasize the potential of integrating microbiota modulation with traditional cardiovascular care, offering a holistic approach to managing atherosclerosis. Important pathways involve the translocation of inflammatory microbial components, modulation of lipid metabolism through metabolites such as trimethylamine-N-oxide (TMAO), and the production of short-chain fatty acids (SCFAs) that influence vascular health. Studies reveal distinct microbial profiles in atherosclerosis patients, with increased pathogenic bacteria (Megamonas, Veillonella, Streptococcus) and reduced anti-inflammatory genera (Bifidobacterium, Roseburia), highlighting the potential of these profiles as biomarkers and therapeutic targets. Probiotics are live microorganisms that have health benefits on the host. Prebiotics are non-digestible dietary fibers that stimulate the growth and activity of beneficial gut bacteria. Interventions targeting microbiota, such as probiotics, prebiotics, dietary modifications, and faecal microbiota transplantation (FMT), present effective approaches for restoring microbial equilibrium and justifying cardiovascular risk. Future research should focus on longitudinal, multi-omics studies to clarify causal links and refine therapeutic applications.

Background and Objectives: Colorectal cancer is a major contributor to global cancer morbidity and mortality. Surgical resection remains the cornerstone of treatment, but postoperative complications can significantly affect patient outcomes. Identifying factors that influence postoperative morbidity and mortality is crucial for optimizing patient care. This study aims to evaluate the impact of preoperative, intraoperative, and postoperative factors on surgical outcomes in patients with colorectal cancer. Methods: A retrospective cohort study was conducted on 688 patients who underwent colorectal cancer surgery within a 10-year period. Data collected included demographic information, comorbidities, laboratory values, surgical details, and postoperative outcomes. Statistical analyses were performed using chi-square tests for categorical variables and t-tests for continuous variables. Multivariate logistic regression was used to identify independent predictors of postoperative complications and mortality. Results: Postoperative complications occurred in 28.5% of patients, and the 30-day mortality rate was 5.2%. Preoperative factors such as elevated C-reactive protein (CRP) levels (p < 0.001), low albumin levels (p = 0.003), a high American Society of Anesthesiologists (ASA) score (p < 0.001), and presence of comorbidities like diabetes and hypertension (p = 0.005) were significantly associated with increased postoperative complications. Intraoperative factors such as blood loss greater than 500 mL (p < 0.001) and longer operative time (p = 0.021) were also significant predictors of adverse outcomes. Multivariate analysis identified elevated CRP (OR 2.1, 95% CI 1.5–2.9), low albumin (OR 1.8, 95% CI 1.3–2.5), and blood loss > 500 mL (OR 2.4, 95% CI 1.7–3.4) as independent predictors of postoperative complications. Conclusions: Preoperative inflammatory markers, nutritional status, ASA score, comorbidities, and intraoperative factors like blood loss significantly influence postoperative outcomes in colorectal cancer surgery. Recognizing these risk factors allows for better preoperative optimization and surgical planning, potentially reducing postoperative morbidity and mortality.

Background and Aims: High-grade gastrointestinal neuroendocrine neoplasms (GI-NENs) are divided into well-differentiated G3 neuroendocrine tumors (NETs G3) and neuroendocrine carcinomas (NECs), having identical cut-offs of proliferation, but different biomolecular origins. This translates in distinct treatment choices. Our aim was to establish if p53/Rb1 immunohistochemical status in GI-NENs with Ki67 index >20% can predict the histopathological diagnosis. Methods: p53/Rb1 immunolabelling was performed on 42 cases of high-grade GI-NENs, diagnosed as NET G3, NEC and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) with NEC component. Immunolabeled slides were digitally scanned, with automatic quantification of p53 and Rb1, blind to the diagnosis. Results: The p53 positive percentage was stratified; two cut-offs were selected, naming the intervals as N (null, 20%). The Rb1 expression loss in >90% of neoplastic cells was considered mutational. NETs G3 mainly showed the T status (14/16, 87.5%), followed by N (1/16, 6.25%) and C (1/16, 6.25%); NECs and NEC components in MiNENs predominantly expressed the C status (19/26, 73.08%), followed by N (5/26, 19.23%) and T (2/26, 7.69%) (p<0.001, χ 2 =27.017). NET G3s showed positive expression for Rb1; 73.08% of NECs expressed negative Rb1 (p<0.001, χ 2 =21.351). NECs and NEC components in MiNENs showed Rb1 mutational status in 13 C cases (13/19, 68.42%), 4 N cases (4/5, 80%) and in both the T cases (p=0.002, χ 2 =11.187). Conclusions: Our results highlight the correlations between the p53/Rb1 immunostainings and the histopathological diagnosis of high-grade GI-NENs. NECs and NEC components in MiNENs showed a p53 mutational status (0% or 21-100%) and predominantly negative Rb1 expression. NETs G3 showed a p53 wild-type status (1-20%) and retained Rb1 expression. These findings suggest that the differential diagnosis of high-grade GI-NENs may benefit from p53/Rb1 immunohistochemical tests in everyday practice.

The global rise in type 2 diabetes mellitus (T2DM) calls for an urgent focus on lifestyle interventions, particularly physical activity, as a critical factor in its management and prevention. This systematic review evaluates the impact of physical activity and sedentary behavior on glycemic control in individuals with T2DM. Studies included in this review were selected based on specific criteria: randomized controlled trials involving adults aged 18 and older, published in English between January 2018 and May 2024, with full-text availability and quantifiable outcome results. Exclusion criteria included non-peer-reviewed research, small sample sizes, and studies limited to abstracts, posters, or editorials. The analysis of the selected studies revealed that regular physical activity, including aerobic exercises and resistance training, significantly improves glycemic control as measured by fasting blood glucose (FBG) and glycated hemoglobin (HbA1C) levels. Reductions in sedentary behavior were also associated with better metabolic outcomes, highlighting the importance of integrating physical activity into daily routines for individuals with T2DM. These findings feature the need for continued research to refine and optimize lifestyle interventions to mitigate the global burden of T2DM.

Background: Hydatid disease, caused by the larval form of Echinococcus granulosus, is a rare but potentially life-threatening condition during pregnancy, with an estimated incidence of 1 in 20,000 to 30,000 gestations. Physiological immunosuppression and increased placental steroid levels during pregnancy may promote cyst growth, elevating the risk of rupture, which can result in anaphylactic shock, sepsis, or widespread peritoneal dissemination. Diagnostic imaging, particularly ultrasonography, plays a central role in detection, while treatment decisions are complicated by the lack of standardized guidelines and the need to balance maternal–fetal safety. Methods: This case report describes a 29-year-old pregnant woman at 22 weeks’ gestation who was incidentally diagnosed with two large hepatic hydatid cysts during a routine ultrasound. Results: Given the high rupture risk, she underwent successful laparoscopic surgery in the second trimester, followed by careful monitoring and elective cesarean delivery at term. A third retroperitoneal cyst, initially managed conservatively, was excised postpartum. Conclusions: This case highlights the critical importance of individualized, multidisciplinary management in achieving favorable maternal and neonatal outcomes in complex presentations of hydatid disease during pregnancy.

Background and Objectives: Intestinal endometriosis is an exceptionally rare cause of intestinal obstruction. This case report and literature review aim to highlight the clinical presentation, diagnostic challenges, and surgical management of this condition. Materials and methods: We report the case of a 50-year-old female patient who presented diffuse abdominal pain, nausea, vomiting, a distended abdomen, and an absence of intestinal transit for gas and faeces. Initial symptoms included flatulence and constipation, which gradually worsened for two months prior to the patient’s hospital admission, leading to acute intestinal obstruction. Diagnostic investigations, including blood tests, ultrasound (USG), X-ray, and a contrast-enhanced computer tomography (CT) scan, revealed significant small bowel dilatation and an ileal volvulus. The patient underwent urgent hydro-electrolytic and metabolic rebalancing followed by a median laparotomy surgical procedure. Intraoperative findings included a distended small intestine and an obstructive ileal volvulus, and required an 8 cm segmental enterectomy and terminal ileostomy. Results: Postoperative recovery was slow but favourable, with a gradual digestive tolerance. Histopathological examination of the resected ileum revealed intestinal endometriosis characterized by a fibro-conjunctive reaction and nonspecific chronic active inflammation. Five months later, the patient underwent a successful reversal of the ileostomy with a mechanical lateral anastomosis of the cecum and ileum, resulting in a favourable postoperative course. Conclusions: This case underscores the importance of considering intestinal endometriosis in women presenting with unexplained gastrointestinal symptoms and highlights the need for timely surgical intervention and careful postoperative management. Further research is required to better understand the pathophysiology and optimal treatment strategies for intestinal endometriosis.
