Background: Differences in skin color have socioeconomic and health implications; however, gaps persist in understanding health-related quality of life (HRQoL) perception.

Aims: To examine whether skin color differences influence HRQoL in obese patients undergoing Roux-en-Y gastric bypass surgery.

Methods: Cross-sectional study with participants of both genders, aged 18 to 60, and three to six months postoperatively. Data were collected from October 2018 to July 2019 at a bariatric clinic in Salvador, Bahia. Skin color, Moorehead-Ardelt II Quality of Life Questionnaire (MAQOL-II) scores, anthropometric measurements, socioeconomic status, physical activity, and body image perceptions were recorded.

Results: Of 196 patients, 67.35% were Black. "Self-esteem" in MAQOL-II demonstrated the most significant post-surgical improvement, with 62.8% reporting "much better" outcomes. Adjusted residuals associated "much better" and "unchanged" responses with skin color. The overall MAQOL-II score indicated lower HRQoL scores (M=1.65; standard deviation - SD=0.98) for individuals with black skin compared to those with white skin. Analyzing questionnaire responses, both racial groups exhibited equal percentages (45.3%) reporting "much better" and "better" post-surgery progress. However, no statistically significant differences in HRQoL were observed when comparing skin color.

Conclusions: Skin color appears not to significantly impact the HRQoL of obese patients undergoing Roux-en-Y gastric bypass.

Background: Inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), lacks a known etiology. Although clinical symptoms, imaging, and colonoscopy are common diagnostic tools, fecal calprotectin (FC) serves as a widely used biomarker to track disease activity. Metabolomics, within the omics sciences, holds promise for identifying disease progression biomarkers. This approach involves studying metabolites in biological media to uncover pathological factors.

Aims: The purpose of this study was to explore fecal metabolomics in IBD patients, evaluate its potential in differentiating subtypes, and assess disease activity using FC.

Methods: Cross-sectional study including IBD patients, clinical data, and FC measurements (=200 μg/g as an indicator of active disease).

Results: Fecal metabolomics utilized chromatography mass spectrometry/solid phase microextraction with MetaboAnalyst 5.0 software for analysis. Of 52 patients (29 UC, 23 CD), 36 (69.2%) exhibited inflammatory activity. We identified 56 fecal metabolites, with hexadecanoic acid, squalene, and octadecanoic acid notably distinguishing CD from UC. For UC, octadecanoic and hexadecanoic acids correlated with disease activity, whereas octadecanoic acid was most relevant in CD.

Conclusions: These findings highlight the potential of metabolomics as a noninvasive complement for evaluating IBD, aiding diagnosis, and assessing disease activity.

Colorectal cancer (CRC) is a common disease, with incidence in Brazil of 45,630 new cases per 100,000 inhabitants between 2023-2025. Risk factors for CRC can be evaluated between environmental and hereditary and their mode of presentation are classified as sporadic, inherited and familial. Sporadic disease is characterized by the absence of a family history and accounts for approximately 70% of all colorectal cancers, being more common over 50 years of age, with dietary and environmental factors implicated in its pathogenesis. Sporadic disease is characterized by the absence of a family history and accounts for approximately 70% of all colorectal cancers, being more common over 50 years of age, with dietary and environmental factors implicated in its pathogenesis. The percentage of patients with a true hereditary genetic predisposition is less than 10%, and these are related to the presence or absence of colonic polyps as an important manifestation of the disease. Non-polyposis diseases are known as hereditary non-polypomatous colorectal cancer (HNPCC) or Lynch syndrome, and polyposis diseases are familial adenomatous polyposis (FAP), MUTYH-associated polyposis (MAP), and hamartomatous polyposis syndromes (e.g., Peutz-Jeghers, juvenile polyposis, phosphatase and tensin homologue - PTEN, Cowden syndrome). These diseases are linked to a high risk of developing cancer. With the development of treatments in metastatic disease and the use of targeted therapies and their biomarkers, it was possible to evaluate them within clinical studies both in the primary tumor and in the correspondence of metastases.

Background: The carcinogenesis of colorectal cancer is well understood. Adenomas are the precursor lesions in about 70% of cases, highlighting the importance of screening programs.

Aims: The aim of this study was to analyze the effectiveness of colonoscopy examinations performed in a private tertiary service by calculating the polyp detection rate (PDR) and adenoma detection rate (ADR) and comparing these rates with literature data.

Methods: This retrospective observational study evaluated colonoscopies performed at Hospital Centro Médico de Campinas between 2018 and 2020. It assessed the indications and complications of colonoscopy, sex, age group, bowel preparation, cecal intubation rate, ADR, PDR, and advanced adenoma detection rate (AADR).

Results: During the period, 3,686 colonoscopies were performed, and 3,076 were included in the analysis. The mean patient age was 57.2 years, and most patients were female (53.5%). Complications occurred in 39 colonoscopies (1.3%), with bleeding in six cases and perforation in one case. Tubular adenoma was the most prevalent histological subtype found in 20% of tests and in 62.7% of those with positive findings. The PDR was 23% and significantly increased with advancing age (p<0.01). The ADR was 20% and also significantly increased with age (p<0.001). This rate was higher in men (27%). The AADR was 4%.

Conclusions: Colonoscopy is an effective polyp detection method, and the PDR was higher in men and significantly increased with age. The ADR and AADR were comparable to the literature data.

Background: Patients undergoing Crohn's disease (CD) surgery may develop a higher rate of postoperative complications (POC) than other patients.

Aims: The aim of this study was to investigate factors determining POC in patients with CD undergoing urgent laparotomy.

Methods: This is a retrospective cohort study conducted on adult patients undergoing urgent laparotomy for CD. Clinical and surgical variables, medication history, American Society of Anesthesiologists classification, and POC were investigated. Data collection and management were carried out using the REDCap software (REDCap electronic data capture tools) hosted at the hospital institution. For statistical analysis, the χ2 (or Fisher's exact) test, Student's t-test, Mann-Whitney test, and simple and multiple multilevel logistic regression analyses were used.

Results: There was an association regarding the history of adalimumab use (p=0.04, OR 2.8, 95%CI 1.03-7.65), previous use of prednisone (p<0.01, OR 2.03, 95%CI 2.00-2.05), urgent surgery indications (p<0.01, OR=4.32, 95% CI=1.58-11.82), mechanical anastomosis (p=0.02, OR=0.22, 95%CI 0.06-0.80), unexpected intraoperative findings (p=0.02, OR 10.46, 95%CI 1.50-72.99), length of hospital stay greater than 10 days (p<0.01, OR 16.86, 95%CI 2.99-94.96), unplanned intensive care unit (ICU) admission (p=0.01, OR 15.06, 95%CI 1.96-115.70), and planned ICU admission (p<0.01, OR 18.46, 95%CI 3.60-94.51). On multivariate analysis, there was an association between the indication of urgent surgery (or emergency) (p=0.01, OR 4.38, 95%CI 1.43-13.37) and unexpected intraoperative findings (p=0.03, OR 8.11, 95%CI 1.21-54.50).

Conclusions: Unexpected changes and urgent surgical indications are considered risk factors for POC in patients with CD.

Liver metastases from melanomas, sarcomas, and renal tumors are less frequent. Treatment and prognosis will depend on whether they are isolated or multiple, size and location, the presence or absence of extrahepatic neoplastic disease, age, stage of the initial disease, initial treatments instituted, time of evolution, and clinical condition of the patient. Recently, a high number of oncological therapies including monotherapy or in combination, neoadjuvants or adjuvants, and immuno-oncological treatments have been developed and tested, increasing disease-free time and survival.

Background: The COVID-19 pandemic has overloaded healthcare systems worldwide. Other diseases, such as neoplasms, including gastric cancer, remained prevalent and had their treatment compromised.

Aims: The aim of this study was to evaluate the impact of the COVID-19 pandemic on the treatment of gastric cancer and adherence to the recommended preoperative COVID-19 screening protocol.

Methods: A retrospective study evaluated patients diagnosed with gastric adenocarcinoma who underwent surgical treatment between 2015 and 2023.

Results: A total of 769 patients with gastric cancer were evaluated and organized into two groups: (i) pre-COVID group and (ii) COVID group. The pre-COVID group consisted of 527 patients operated on between 2015 and 2019, and the COVID group consisted of 242 patients from 2020 to 2023. The average number of surgical procedures per year in the pre-COVID group was 105 and 81 in the COVID group. There was a statistically significant difference between ASA classification (p=0.002) and clinical staging (p=0.015), which were worse in the COVID group. We observed an increase in diagnostic surgeries (p=0.026), with an increase in the minimally invasive route (p<0.001). In patients undergoing curative surgery, there was a greater indication for postoperative ICU (p=0.022) and neoadjuvant chemotherapy (p<0.001). There was no difference in 30- and 90-day mortality.

Conclusions: The surgical and oncological outcomes for patients operated on during the pandemic remained uncompromised, even though many presented with more advanced initial stages and poorer clinical performance. High adherence to protocols and a low rate of complications related to coronavirus indicate that surgeries were performed safely during this period.

Background: Obesity is a predisposing factor for serious comorbidities, particularly those related to elevated cardiovascular mortality. The atherogenic index of plasma (AIP) has been shown to be a useful indicator of patients with insulin resistance.

Aims: The aim of this study was to assess cardiovascular risk before and after surgical treatment of obesity.

Methods: A total of 615 patients undergoing bariatric surgery between 2007 and 2012 were evaluated using the analysis of electronic records (triglyceride/high-density lipoprotein cholesterol) before and after surgery. The AIP levels >3.5 mg/dL for men and >2.5 mg/dL for women were insulin-resistant and predisposed to cardiovascular events.

Results: A total of 117 men had an AIP >3.5 mg/dL during the preoperative period, 13.5% during the early postoperative period, 14.3% during the intermediate period, and 18.2% during the late postoperative period. Among 498 women, 56.2% had an AIP >2.5 mg/dL before surgery, 17.9% in early postoperative period, 13.5% in the intermediate period, and 11.4% in the late period.

Conclusions: Bariatric surgery resulted in a significant effect on the AIP, insulin resistance, metabolic syndrome, and therefore, the risk of cardiovascular diseases.

Complete removal of metastatic disease and maintenance of an adequate liver remnant remains the only treatment option with curative intent concerning colorectal liver metastases. Surgery impacts on the long-term prognosis and complications adversely affect oncological results. The actual morbidity involving this scenario is debatable and estimated to be ranging from 15% to 50%. Postoperative complications eventually lead to an increase in both mortality rates and tumor recurrence. Biliary fistula and liver failure are the leading complications following liver resection to metastatic colorectal cancer. Prophylactic drainage does not prevent fistulas or hemorrhage. Drainage along with endoscopic intervention and/or surgery may be necessary for grade B and C fistulas. Liver failure is a potentially lethal complication with few therapeutic options. Patient selection and preoperative care are crucial for its prevention.
