ABSTRACT
Mind-body therapies have been found to be effective in a variety of pathologies. The purpose of this study was to evaluate the efficacy of meditation-based therapies in relieving the symptoms severity, quality of life, stress and other associated mood conditions, in individuals with chronic neuropathy of various etiologies. A systematic review of randomized controlled trials, involving adult patients with persistent peripheral neuropathy, was performed. Seven article databases were searched. A meta-analysis was conducted to assess the benefits of meditation-based therapy on symptomatology, quality of life, anxiety, depression, perceived stress, sleep quality and mindfulness score. Ten of the 1133 reviewed papers were selected for quantitative review. The meditation group had a lower standardized mean difference (SMD) score (-0.47 (95% CI: -0.97 to 0.02), p=0.062) for neuropathic pain severity score; lower anxiety scores (-2.5 (95% CI: -3.68 to -1.32), p=<0.001); lower depression scores (-1.53 (95% CI: -2.12 to -0.93), p=<0.001); lower perceived stress (-1.06 (95% CI: -3.15 to 1.04), p=0.323); higher quality of life scores (2.19 (95% CI: -0.65 to 5.03), p=0.13); lower sleep quality scores (-1.27 (95% CI: -4.22 to 1.67), p=0.397); higher mindfulness scores (6.71 (95% CI: 4.09 to 9.33), p=<0.001); and lower pain severity at 1 to 1.5 follow up (-1.75 (95% CI: -2.98 to -0.51), p=0.006). Some of the results were characterized by a substantial, statistically significant heterogeneity. Nevertheless, a major part of the results pointed in the same direction, improving symptomatology with meditation-based therapy. The studies had a risk of bias mostly regarding the measurement of the outcome, randomization process and selection of the reported result. The current study discovered that the meditation group had significantly lower pain (at 1 to 1.5 months follow-up) anxiety, and depression scores and higher mindfulness scores at the end of the interventions.
ABSTRACT
Introduction: Celiac disease (CD) is a chronic autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals, presenting with a diverse range of symptoms that extend beyond the gastrointestinal tract. The condition's systemic nature is evidenced by its extra-digestive manifestations, which can affect various organs including the skin, joints, liver, and nervous system. Methods: This descriptive, retrospective study was conducted at a tertiary care center, focusing on adult patients diagnosed with CD who exhibited extra-digestive symptoms. Data were extracted from medical records of patients admitted between January 1, 2010 and June 30, 2024. Variables included demographic information, primary diagnosis, and associated extra-digestive manifestations. Descriptive statistical methods were employed for data analysis. Results: The sample included 108 patients with CD, the mean age was 43.21 years, with a predominance of females (76.85%). Iron deficiency anemia was the most common extra-digestive manifestation, affecting 20.37% of patients, followed by hypoproteinemia (18.52%) and Hashimoto's thyroiditis (14.81%). Co-occurrence analysis revealed frequent combinations of conditions, such as anemia with cardiovascular diseases and depressive disorders. Notable associations with neurological conditions like gluten ataxia and peripheral neuropathy were also observed. Conclusion: This study highlights the extensive extra-digestive manifestations of celiac disease, underscoring its systemic impact. The high prevalence of autoimmune conditions such as Hashimoto's thyroiditis and rheumatoid polyarthritis among CD patients reflects the need for holistic management strategies. Discrepancies between our findings and existing literature, particularly regarding skin and neurological conditions, emphasize the need for further research to better understand these associations and the long-term effects of a gluten-free diet.
ABSTRACT
Introduction: We aimed to evaluate social media addiction in Romanian undergraduate nursing students and its association with academic performance, depression, and anxiety. Methods: We used a cross-sectional online survey to collect data among nursing undergraduate students enrolled at the University of Medicine and Pharmacy "Iuliu Hatieganu", Cluj-Napoca, Romania. The Social Media Addiction Scale-Student Form (SMAS-SF), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI) were used to assess social media addiction, depression, and anxiety, respectively. Results: A total of 90 nursing students participated in the study, of which 82 (91.1%) were females and 81 (90%) were of Romanian ethnicity. The median age of participants was 21 years (18-40). Males showed higher BDI total scores, SMAS-SF total scores, and STAI scale A state anxiety compared to females, and females showed higher STAI scale A trait anxiety compared to males, although these results were not statistically significant. Also, we found no significant difference in these variables between participants from different study years. Participants with no or mild depression had a significantly higher academic performance (p-value = 0.001), lower SMAS-SF (p-value = 0.004), and lower STAI scores (p-value < 0.001) compared to participants with borderline, moderate, or severe depression after performing multivariate regression analysis. Conclusions: Our study demonstrated that depression was significantly associated with social media addiction, anxiety, and lower academic performance in Romanian undergraduate nursing students.
ABSTRACT
Background/Aims: Patients with diverticular disease (DD) frequently have abnormal bowel movements. However, it is unknown whether the entity of these alterations is associated with the severity of DD. We aimed to assess bowel habits and their relationship with the severity of DD according to Diverticular Inflammation and Complication Assessment (DICA) classification, Combined Overview on Diverticular Assessment (CODA) score, and fecal calprotectin (FC). Methods: An international, multicenter, prospective cohort study was conducted in 43 centers. A 10-point visual analog scale (VAS) was used to assess the severity of constipation and diarrhea. The association of constipation and diarrhea with DICA classification, CODA score, and basal FC was tested using non-parametric tests. Survival methods for censored observations were applied to test the association of constipation and diarrhea with the incidence of acute diverticulitis over a 3-year follow-up. Results: Of 871 patients with DD were included in the study. Of these, 208 (23.9%) and 199 (22.9%) reported a VAS score for constipation and diarrhea at least 3 at baseline, respectively. Higher constipation and diarrhea scores were associated with increasing DICA classification, CODA score and basal FC (P< 0.001). Constipation and diarrhea scores were independently associated with an increased hazard of developing acute diverticulitis (hazard ratio [HR]constipation = 1.15 per 1-VAS point increase, 95% confidence interval [CI], 1.04-1.27; P=0.004; and HRdiarrhea =1.14; 95% CI, 1.03-1.26; P=0.014, respectively). Conclusions: In newly diagnosed patients with DD, higher endoscopic and combined scores of DD severity were associated with higher scores of constipation and diarrhea at baseline. Both constipation and diarrhea were independent prognostic factors of acute diverticulitis.
ABSTRACT
Background/Aims: Disruptions in tight junction (TJ) protein expression leading to duodenal epithelial barrier impairment may contribute to increased intestinal permeability, potentially playing a role in functional dyspepsia (FD) pathophysiology. Currently published studies evaluated the role of several TJ proteins in FD patients with inconsistent results. Therefore, we conducted this systematic review and metaanalysis to evaluate the duodenal mucosal expression of several TJ proteins in FD. Methods: We performed a systematic electronic search on PubMed, EMBASE, and Scopus using predefined keywords. Diagnosis of FD by Rome III or Rome IV criteria was considered acceptable. Full articles satisfying our inclusion and exclusion criteria were included. The principal summary outcome was the mean difference of several TJ proteins in FD patients and control subjects. Results: A total of 8 and 5 studies were included in our qualitative and quantitative synthesis, respectively, with a total population of 666 participants, out of which 420 were FD patients. No significant differences were observed between FD patients and controls in the expression of claudin-1 (-0.102 [95% CI, -0.303, 0.099]), claudin-2 (0.161 [95% CI, -0.134, 0.456)], claudin-3 (0.278 [95% CI, -0.280, 0.837]), claudin-4 (0.045 [95% CI, -0.264, 0.354]), ZO-1 (-0.221 [95% CI, -0.683, 0.241]), ZO-2 (-0.070 [95% CI, -0.147, 0.007]), ZO-3 (-0.129 [95% CI, -0.376, 0.118]), ß-catenin (-0.135 [95% CI, -0.484, 0.214]), E-cadherin (-0.083 [95% CI, -0.229, 0.063]), and occludin (-0.158 [95% CI, -0.409, 0.093]). Conclusions: The expressions of all evaluated proteins including claudin-1, claudin-2, claudin-3, claudin-4, ZO-1, ZO-2, ZO-3, ß-catenin, E-cadherin, and occludin did not significantly differ between FD patients and controls. However, due to the limited number of included studies, results should be interpreted with caution.
ABSTRACT
Introduction Our study aimed to compare meditation and compassion-based group therapy with the standard of care in patients with eating disorders, drug addiction, alcohol addiction, and depression, concerning acceptance, mindfulness awareness, self-compassion, and psychological distress. Methods A controlled designed study was performed, comparing meditation and compassion-focused group therapy added to the standard of care with the standard of care alone, on patients with eating disorders, drug addiction, alcohol addiction, and mood disorders. Four validated questionnaires were administered: the Acceptance and Action Questionnaire-II (AAQ-II), which assesses the ability to be fully in touch with the present moment; the Mindful Attention Awareness Scale (MAAS), which assesses the ability to experience consciously what is happening in the present moment; the Self-Compassion Scale (SCS), which assesses self-compassion characteristics, including loving-kindness; and the Symptom Checklist-90 (SCL-90), which measures psychological distress (anxiety, depression, psychotic behavior, etc.). Results There was a total of 75 subjects, out of which 48 represented the experimental group, and 27 represented the control group. The overall mean age of the subjects was 44.8 ± 13.2 years. There were statistically significant increases in the experimental group (baseline vs. end of study) for the AAQ-II, MAAS, and SCS scores, and a statistically significant decrease in the SCL-90 score. In the control group, there was a statistically significant decrease in the SCL-90 score, but no significant differences for other measurements. The comparisons between the two groups at the end of the study were as follows: AAQ-II: 0.7 (-5.74 to 7.15), p = 0.827; MAAS: 4.78 (-3.19 to 12.75), p = 0.233; SCS: 5.89 (-3.18 to 14.96), p = 0.199; SCL-90: -0.26 (-0.62 to 0.1), p = 0.157. Conclusion Within the experimental group, all scales improved statistically significantly. There were no statistically significant differences at the end of the study concerning the four scales between the groups. The comparison between groups was limited by data availability.
ABSTRACT
BACKGROUND: In instances where individuals manifest elevated transaminase levels without a clearly discernible cause, a comprehensive patient history proves invaluable in unveiling latent triggers. In this report, we present 2 cases of herb-induced liver injury (HILI) characterized by severe hypertransaminasemia attributed to the consumption of Chelidonium majus L . (also known as greater celandine [GC]), an agent considered an alternative therapeutic remedy. AREAS OF UNCERTAINTY: Exploring the occurrence and range of clinical manifestations in HILI linked to Chelidonium majus L ., while also investigating the potential triggers and predisposing factors for hepatotoxic reactions post Chelidonium majus L. usage, remains challenging due to the absence of definitive laboratory tests to identify the causative agent. DATA SOURCES: Two case reports were detailed, and a systematic literature review using PubMed was conducted including published literature till March 2023. Moreover, a manual search of reference lists of pertinent articles was performed to identify any additional relevant missed publications. RESULTS: In the first case, a 64-year-old woman presented with jaundice, revealing a 1-month history of using GC capsules to manage gallstones. Diagnostic assessment identified HILI, gallstones, and choledocolithiasis, with transaminase levels exceeding 1000 IU/L. After discontinuing GC and receiving intravenous therapy with amino acids and phospholipids, the patient's condition significantly improved. Subsequently, she underwent endoscopic common bile duct stone removal and cholecystectomy. In the second case, a 66-year-old woman presented with elevated liver function test results discovered incidentally during musculoskeletal pain evaluation. Upon further questioning, the patient disclosed regular consumption of GC tea for "health promotion." Following intravenous therapy using amino acids and phospholipids, her transaminase levels returned to normal. The literature review identified 38 cases of HILI associated with GC preparations, primarily in adult women aged 27-77 years, with a predominant reporting location in Germany. Various forms of GC were used, with treatment durations ranging from 1 week to a year. Discontinuation of GC generally led to recovery in these cases. CONCLUSION: Chelidonium majus L ., a potent herb often used in alternative medicine, has significant hepatotoxic potential, requiring physicians to be vigilant in cases of unexplained liver injury.

Introduction: The relationship between several adipokines and COVID-19 severity has lately been evaluated, results being inconclusive. Therefore, we aimed to assess the association between adipokines in COVID-19 and its severity. Methods: A search was performed in PubMed, Scopus, and Embase using predefined keywords. The Newcastle of Ottawa Scale (NOS) was used for the quality assessment of included studies. The main summary outcome was the mean difference (MD) in adipokine levels. Results: A total of 8 studies involving 473 individuals were included. A significant MD in serum adiponectin levels was demonstrated in mild vs. severe COVID-19 patients (-5.734 [95% CI -11.215 - -0.252]), with no significant MD in mild vs. moderate (-7.117 [95% CI -19.546 - 5.313]), or moderate vs. severe COVID-19 (-1.846 [95% CI -4.516 - 0.824]). Moreover, no significant MD was found in adiponectin and leptin levels when comparing COVID-19 patients vs. controls (-12.675 [95% CI -36.159 - 10.808]) and (8.034 [95% CI -10.403 - 26.471]), respectively. Conclusion: Adiponectin levels were significantly increased in patients with severe compared to mild COVID-19. However, no significant MD was found in adiponectin levels in mild vs. moderate and moderate vs. severe COVID-19 patients, nor in adiponectin and leptin levels in COVID-19 patients vs. controls.
ABSTRACT
Clostridioides difficile infection (CDI) in clinical practice represents a challenge for its management and also prevention of recurrence. Even though there are updated guidelines for infection prevention, control and treatment, CDI remains a leading cause of healthcare acquired diarrhea with increasing incidence in the community. We present here a synthesis of the most recent international guidelines on the management of CDI. In 2021 updated guidelines on the treatment of CDI in adults were published by the Infectious Diseases Society of America (IDSA) and the Society for Healthcare Epidemiology of America (SHEA), American College of Gastroenterology (ACG) and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID). These guidelines focused on CDI management in adults, including new data on the clinical efficacy of Fidaxomicin (FDX) and Bezlotoxumab. The 2017 publication of IDSA and SHEA - Clinical Practice Guidelines for Clostridium difficile infection also included pediatric treatment recommendations that are not a part of the 2021 update. Vancomycin (VAN) treatment for an initial CDI episode remains an acceptable alternative to FDX, considering the monetary and logistical challenge of acquiring FDX. There is growing literature on fecal microbiota transplantation (FMT) and the 2021 guidelines describe its role in severe complicated refractory CDI cases and for which surgical management is not feasible. Moreover, there are new data on the secondary prophylaxis with VAN in refractory CDI in patients with risk factors who receive broad spectrum antibiotics.
ABSTRACT
Background and Objectives: It is crucial to quickly identify those patients who need immediate treatment in order to avoid the various complications related to acute diverticulitis (AD). Although several studies evaluated the neutrophil-to-lymphocyte ratio (NLR) suggesting its predictive value in assessing the severity of AD, results have been inconclusive. Therefore, we aimed to assess the relationship between the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the monocyte-to-lymphocyte ratio (MLR), and systemic immune inflammation (SII) with the severity of AD, the ability to predict the presence or absence of complications, and the recurrence rate, based on the values of inflammatory markers. Materials and Methods: We retrospectively reviewed 147 patients diagnosed with AD between January 2012 to February 2023. Patients were divided into 2 groups, uncomplicated and complicated AD. The characteristics and full blood count between both groups were compared. Results: A total of 65 (44.22%) patients were classified as having complicated AD. The area under the ROC curve (AUROC) defining a Hinchey score ≥ 1b was as follows: SII, 0.812 (95% confidence interval (CI), 0.73 -0.888); NLR, 0.773 (95% CI, 0.676-0.857); PLR, 0.725 (95% CI, 0.63-0.813); MLR: 0.665 (95% CI, 0.542 -0.777). An SII cutoff value of > 1200 marked the highest yield for diagnosing complicated AD, with a sensitivity of 82% and a specificity of 76%. The cumulative recurrence rate was not significantly different in the groups of SII ≥ median vs. SII < median (p = 0.35), NLR ≥ median vs. NLR < median (p = 0.347), PLR ≥ median vs. PLR < median (p = 0.597), and MLR ≥ median vs. MLR < median (p = 0.651). Conclusions: Our study indicates that SII, NLR, and PLR are statistically significant and clinically useful classifying ratios to predict higher Hinchey scores. However, they cannot predict recurrences.

Currently being the seventh most prevalent form of cancer worldwide, and the fifth most common cause of cancer-related death, based on GLOBOCAN 2020 data, gastric cancer is still an important public health problem, despite its dropping incidence. Regions around the world are still at high-risk, mostly in populations with a high prevalence of Helicobacter pylori infection or a carcinogenic favorable diet. Gastric cardia cancer incidence is on the rise in some areas. Great steps were made in the last decades in understanding the pathogenesis of gastric cancer and its risk factors. Host genetic polymorphisms play a quintessential role in disease outcome. Helicobacter pylori eradication and endoscopic surveillance are the most effective options to further decrease gastric cancer incidence. Surgery is required for a curative treatment in most cases. This review summarizes the latest worldwide epidemiological data of gastric cancer and aims to provide an accessible and credible source of evidence for physicians who assess risk factors for gastric cancer.
ABSTRACT
BACKGROUND AND AIMS: The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS: A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS: At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS: FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract. Studies evaluated the effect of several diets on inflammatory markers in IBD patients. Nevertheless, the results have been inconsistent. Therefore, we conducted this review to evaluate the effectiveness of dietary interventions on inflammatory markers in IBD. METHODS: A comprehensive electronic literature search strategy using the PubMed, Embase, and Scopus was conducted in March 2023 and evaluated inflammatory markers included C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and fecal calprotectin (FC), as well as disease severity scores. We included full-text articles that met our inclusion and exclusion criteria. To evaluate the included studies, we used the NHLBI quality evaluation tools. RESULTS: A total of 16 studies were included in our qualitative synthesis. Elemental and polymeric diets showed similar efficacy in reducing Crohn's disease activity index (CDAI) and CRP levels. On the other hand, most studies evaluating the effects of omega 3 fatty acids reported no significant improvement. Moreover, protein supplementation was not seen to improve ESR or CRP levels. Except for improvements in FC levels with IgG4-guided exclusion diet in CD patients with elevated CDAI levels, restrictive diets were successful in controlling functional abdominal symptoms but did not appear to have an impact on inflammation in most studies. Furthermore, disease severity scores, CRP, ESR, and FC levels did not significantly change when eating a high-fiber, low-refined-carb, low-fat diet. CONCLUSIONS: Diet plays a vital role in managing IBD by impacting the inflammatory response. Among the interventions studied, enteral nutrition showed the most promising results, improving patients' inflammatory status. Restrictive diets effectively managed symptoms and clinical remission but had limited impact on inflammatory markers. Supplementing the diet with fatty acids, omega 3, or proteins did not definitively improve patients' condition or inflammation.
ABSTRACT
INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis. METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients. RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission. DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.

BACKGROUND AND AIMS: Current nonalcoholic fatty liver disease (NAFLD) guidelines do not provide any recommendations regarding the waist-to-height ratio (WHtR), a simple obesity metric calculated by dividing waist circumference by height. Therefore, we performed a systematic review and meta-analysis aiming to evaluate WHtR in NAFLD. METHODS: We performed a systematic electronic search on PubMed, Embase, and Scopus, identifying observational studies assessing WHtR in NAFLD. QUADAS-2 tool was used to evaluate the quality of included studies. The two main statistical outcomes were the area under the curve (AUC) and the mean difference (MD). RESULTS: We included a total of 27 studies in our quantitative and qualitative synthesis, with a total population of 93,536 individuals. WHtR was significantly higher in NAFLD patients compared to controls with an MD of 0.073 (95% CI 0.058 - 0.088). This was also confirmed after conducting a subgroup analysis according to the hepatic steatosis diagnosis method, for ultrasound (MD 0.066 [96% CI 0.051 - 0.081]) and transient elastography (MD 0.074 [96% CI 0.053 - 0.094]). Moreover, NAFLD male patients presented significantly lower WHtR compared to female patients (MD -0.022 [95% CI -0.041 - -0.004]). The AUC of WHtR for predicting NAFLD was 0.815 (95% CI 0.780 - 0.849). CONCLUSIONS: WHtR is considerably higher in NAFLD patients compared to controls. Female NAFLD patients present higher WHtR compared to NAFLD male patients. In comparison to other presently suggested scores and markers, the WHtR's accuracy in predicting NAFLD is considered acceptable.

INTRODUCTION: Adipose tissue plays an important role in the pathogenesis of inflammatory conditions. The role of adipokines in inflammatory bowel disease (IBD) has been evaluated in the current literature with conflicting results. The aim of this study was to evaluate adiponectin levels in IBD patients, including Crohn's disease (CD) and ulcerative colitis (UC), compared to controls, as well as further subgroup analyses. Hence, assessing the potential role of adiponectin as a surrogate marker. METHODS: We performed a systematic electronic search on PubMed, Embase, Scopus, and Cochrane Library, including observational or interventional studies evaluating serum or plasma adiponectin levels in IBD patients in humans. The primary summary outcome was the mean difference (MD) in serum or plasma adiponectin levels between IBD patients versus controls. Subgroup analyses were conducted involving adiponectin levels in CD and UC compared to controls, as well as CD compared to UC. RESULTS: A total of 20 studies were included in our qualitative synthesis and 14 studies in our quantitative synthesis, with a total population sample of 2,085 subjects. No significant MD in serum adiponectin levels was observed between IBD patients versus controls {-1.331 (95% confidence interval [CI]: -3.135-0.472)}, UC patients versus controls (-0.213 [95% CI: -1.898-1.472]), and CD patients versus controls (-0.851 [95% CI: -2.263-0.561]). Nevertheless, a significant MD was found between UC patients versus CD patients (0.859 [95% CI: 0.097-1.622]). CONCLUSIONS: Serum adiponectin levels were not able to differentiate between IBD, UC, and CD patients compared to controls. However, significantly higher serum adiponectin levels were observed in UC compared to CD patients.

Diverticular disease (DD) is the most frequent condition in the Western world that affects the colon. Although chronic mild inflammatory processes have recently been proposed as a central factor in DD, limited information is currently available regarding the role of inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α). Therefore, we conducted a systematic review and meta-analysis aiming to assess the mucosal TNF-α levels in DD. We conducted a systematic literature search using PubMed, Embase, and Scopus to identify observational studies assessing the TNF-α levels in DD. Full-text articles that satisfied our inclusion and exclusion criteria were included, and a quality assessment was performed using the Newcastle-Ottawa Scale (NOS). The principal summary outcome was the mean difference (MD). The results were reported as MD (95% confidence interval (CI)). A total of 12 articles involving 883 subjects were included in the qualitative synthesis, out of which 6 studies were included in our quantitative synthesis. We did not observe statistical significance related to the mucosal TNF-α levels in symptomatic uncomplicated diverticular disease (SUDD) vs. the controls (0.517 (95% CI -1.148-2.182)), and symptomatic vs. asymptomatic DD patients (0.657 (95% CI -0.883-2.196)). However, the TNF-α levels were found to be significantly increased in DD compared to irritable bowel disease (IBS) patients (27.368 (95% CI 23.744-30.992)), and segmental colitis associated with diverticulosis (SCAD) vs. IBS patients (25.303 (95% CI 19.823-30.784)). Between SUDD and the controls, as well as symptomatic and asymptomatic DD, there were no significant differences in the mucosal TNF-α levels. However, the TNF-α levels were considerably higher in DD and SCAD patients than IBS patients. Our findings suggest that TNF-α may play a key role in the pathogenesis of DD in specific subgroups and could potentially be a target for future therapies.

Introduction: The role of probiotics/prebiotics in modulating the procarcinogenic effects of microbiota have been studied with inconclusive results. This systematic review aimed to identify the role of several studied interventions on the gut microbiota modulation in humans for the prevention and management of colorectal cancer (CRC). Methods: We conducted a systematic search using PubMed and Cochrane Central electronic databases, identifying clinical studies published within the last 20 years. We performed a qualitative analysis of eligible studies included in our review on each of the 4 investigated topics: CRC potential biomarkers, dietary interventions, probiotic administration in non-surgical and surgical patients, respectively. Results: A total of 54 studies involving healthy volunteers, in addition to colorectal adenoma and CRC patients were included in our qualitative synthesis. We were able to identify bacterial signatures of CRC including Fusobacterium nucleatum and Clostridium butyricum. Moreover, dietary supplementation with oligosaccharides or fibers increased short chain fatty acid-producing bacteria levels, thus inhibiting tumorigenesis. Furthermore, we have confirmed that Lactobacilli and Bifidobacterium intake modulates gut microbiota towards tumor suppression. We have also showed that probiotic intake around colectomy significantly reduces complications. Conclusions: Bacterial metabolism is strongly linked with colonic carcinogenesis and influenced by diet. Probiotics and prebiotics can act as microbiota modulators, suppressing epithelial proliferation and reversing DNA toxicity. As adjuvants to surgery or chemotherapy, Lactobacilli and Bifidobacteria decrease complications. Improved outcomes in CRC patients can possibly be achieved through future research directed towards the benefits of bacterial agents as tumor suppressors or as treatment of oncological therapy resistance.
ABSTRACT
BACKGROUND AND AIMS: The Rome Foundation Global Epidemiology Study (RFGES) assessed the prevalence, burden, and associated factors of Disorders of Gut-Brain Interaction (DGBI) in 33 countries around the world. Achieving worldwide sampling necessitated use of two different surveying methods: In-person household interviews (9 countries) and Internet surveys (26 countries). Two countries, China and Turkey, were surveyed with both methods. This paper examines the differences in the survey results with the two methods, as well as likely reasons for those differences. METHODS: The two RFGES survey methods are described in detail, and differences in DGBI findings summarized for household versus Internet surveys globally, and in more detail for China and Turkey. Logistic regression analysis was used to elucidate factors contributing to these differences. RESULTS: Overall, DGBI were only half as prevalent when assessed with household vs Internet surveys. Similar patterns of methodology-related DGBI differences were seen within both China and Turkey, but prevalence differences between the survey methods were dramatically larger in Turkey. No clear reasons for outcome differences by survey method were identified, although greater relative reduction in bowel and anorectal versus upper gastrointestinal disorders when household versus Internet surveying was used suggests an inhibiting influence of social sensitivity. CONCLUSIONS: The findings strongly indicate that besides affecting data quality, manpower needs and data collection time and costs, the choice of survey method is a substantial determinant of symptom reporting and DGBI prevalence outcomes. This has important implications for future DGBI research and epidemiological research more broadly.
