Recent Immigrants with Inflammatory Bowel Disease Have Significant Health-Care Utilization from Preconception to Postpartum: A Population Cohort Study.

BACKGROUND: Immigrants with inflammatory bowel disease (IBD) may have increased health-care utilization during pregnancy compared to non-immigrants, though this remains to be confirmed. We aimed to characterize this between these groups. METHODS: We accessed administrative databases to identify women (age 18-55) with IBD with a singleton pregnancy between 2003-2018. Immigration status was defined as recent (< 5 years of date of conception), remote (≥ 5 years since date of conception), and none. Differences in ambulatory, emergency department (ED), hospitalization, endoscopic, and prenatal visits during 12-months preconception, pregnancy and 12-months postpartum were characterized. Region of immigration origin was ascertained. Multivariable negative binomial regression was performed for adjusted incidence rate ratios (aIRR) with 95% confidence intervals (95% CI). RESULTS: 8880 pregnancies were included, 8304 in non-immigrants, 96 in recent immigrants, 480 in remote immigrants. Compared to non-immigrants, recent immigrants had the highest rates of IBD-specific ambulatory visits during preconception (aIRR 3.06, 95% CI, 1.93-4.85), pregnancy (aIRR 2.15, 95% CI, 1.35-3.42), and postpartum (aIRR 2.21, 1.37-3.57) and the greatest rates of endoscopy visits during preconception (aIRR 2.69, 95% CI, 1.64-4.41) and postpartum (aIRR 2.01, 95% CI, 1.09-3.70). There were no differences in ED and hospitalization visits between groups though those arriving from the Americas were the most likely to be hospitalized for any reason. All immigrants with IBD were less likely to have a first trimester prenatal visit. CONCLUSION: Recent immigrants were more likely to have IBD-specific ambulatory care but less likely to receive adequate prenatal care during pregnancy.

A Population-Based Matched Cohort Study of Digestive System Cancer Incidence and Mortality in Individuals With and Without Inflammatory Bowel Disease.

INTRODUCTION: To study digestive system cancer risks in inflammatory bowel diseases (IBD) in the biologic era. METHODS: We used population-level administrative and cancer registry data from Ontario, Canada (1994 - 2020) to compare people with IBD to matched controls (1:10 by sex and birth year) on trends in age-sex standardized cancer incidence and risk ratios of incident cancers and cancer-related deaths. RESULTS: Among 110,919 IBD and 1,109,190 controls, colorectal cancer (CRC) incidence (per 100,000 person-years) declined similarly in people with ulcerative colitis (average annual percentage change (AAPC) -1.81; 95% CI, -2.48, -1.156) and controls (AAPC -2.79; 95% CI, -3.44, -2.14), while small bowel cancer incidence rose faster in those with Crohn's disease (AAPC 9.68; 95% CI, 2.51, 17.3) than controls (AAPC 3.64; 95% CI, 1.52, 5.80). Extra-intestinal digestive cancer incidence rose faster in people with IBD (AAPC 3.27; 95% CI, 1.83, 4.73) than controls (AAPC -1.87; 95% CI, -2.33, -1.42), particularly for liver (IBD AAPC 8.48; 95% CI, 4.11, 13.1) and bile duct (IBD AAPC 7.22; 95 % CI, 3.74, 10.8) cancers. Beyond 2010, the incidences (and respective mortality rates) of colorectal (1.60; 95% CI, 1.46, 1.75), small bowel (4.10; 95% CI 3.37, 4.99), bile duct (2.33; 95% CI 1.96, 2.77) and pancreatic (1.19; 95% CI, 1.00, 1.40) cancers, were higher in people with IBD. DISCUSSION: Cancer incidence is declining for CRC and rising for other digestive cancers in people with IBD. Incidence and mortality remain higher in IBD than controls for colorectal, small bowel, bile duct and pancreatic cancers.

The COVID-19 Pandemic Significantly Impacts Pregnancy Planning and Mental Health of Women With Inflammatory Bowel Disease.

BACKGROUND AND GOALS: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted daily life, particularly in those with inflammatory bowel disease (IBD). We aimed to determine the impact of the pandemic on the pregnancy planning and mental health of women with IBD. METHODS: Women with IBD (age 18 to 45 y) were asked to complete anonymous surveys on the impact of the COVID-19 pandemic on pregnancy planning and mental health symptoms such as stress (Perceived Stress Scale), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder-7). Univariate and multivariable analyses were conducted to identify risk factors associated with stress, depression, and anxiety during the pandemic. RESULTS: Seventy-three women with IBD were included (mean age: 32.1). Of 39 patients who were preconception, 20 (51.3%) reported a significant impact of the pandemic on pregnancy planning, with common reasons for not planning conception being fear of transmission of the virus to the fetus, lack of social supports, and no desire to be in hospital during pregnancy. Over half of all women reported an increase in stress and depression symptoms during the pandemic, with over half also reporting symptoms of anxiety. On multivariable linear regression analyses, increased anxiety levels were a significant predictor of increased stress and depression symptoms during the pandemic. Urban residence and younger age were significant predictors of increased anxiety symptoms during the pandemic. CONCLUSION: A significant proportion of women with IBD experienced an impact of the COVID-19 pandemic on pregnancy planning and mental health illnesses such as stress, depression, and anxiety.

Impact of Disease Activity and Inflammatory Bowel Disease Subtype on Quality of Life in Preconception and Pregnant Patients.

BACKGROUND: Inflammatory bowel disease (IBD) and pregnancy both impact health-related quality of life (HRQoL). However, little is known about IBD-related HRQoL around pregnancy. AIMS: To assess the trajectory and predictors of HRQoL in preconception and pregnant patients with Crohn's disease (CD) and ulcerative colitis (UC). METHODS: Preconception and pregnant patients with IBD were followed prospectively from preconception to twelve months postpartum at a tertiary referral centre. Participants completed the Short IBD Questionnaire (SIBDQ) and were assessed for clinical disease activity (modified Harvey Bradshaw Index or partial Mayo score) and objective disease activity (C-reactive protein [CRP], fecal calprotectin [FCP]). RESULTS: A total of 61 patients with IBD (25 CD, 36 UC) were included. During preconception, patients with UC had higher SIBDQ bowel and social sub-scores than those with CD, but this reversed during postpartum. Patients with CD but not UC developed a significant, sustained improvement in SIBDQ upon becoming pregnant, which persisted into 12 months postpartum. In a multivariable linear regression model, clinical disease activity negatively predicted SIBDQ at every pregnancy timepoint and up to 12 months postpartum. SIBDQ was significantly lower in patients with CRP ≥ 8.0 mg/L during trimester 1 (T1), but not later in pregnancy. SIBDQ bowel sub-scores were significantly lower in patients with FCP ≥ 250 mg/kg at T2, T3, and 6 months postpartum. CONCLUSIONS: Clinical disease activity is a consistent negative predictor of HRQoL from conception to 12 months postpartum. Patients with UC experience better preconception HRQoL but suffer worse postpartum HRQoL than those with CD.

A Dedicated Pregnancy Clinic Improves Reproductive Knowledge in Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Factors affecting pregnancy-related knowledge in women with inflammatory bowel disease (IBD) remain unknown. We aimed to determine these factors and to assess the impact of a dedicated pregnancy clinic on improving knowledge in women with IBD. METHODS: Adult women with IBD attending the pregnancy IBD clinic at the University of Alberta from 2014 to 2018 were enrolled. Each patient completed the Crohn's and Colitis Pregnancy Knowledge (CCPKnow) questionnaire at baseline and after individualized education delivered at each clinic visit. Knowledge levels were defined as very good if CCPKnow scores ≥ 14. Mean CCPKnow scores were reported with standard deviations (SD) and compared using the paired T test. RESULTS: The mean CCPKnow score in 117 patients at baseline was 9.65 (SD 4.18). Compared to those with disease duration < 5 years, those with disease duration > 5 years had higher rates of very good baseline knowledge (3.0% vs. 26.4%, p = 0.036). Similarly, those on preconception IBD-related therapy were more likely to have very good knowledge compared to those on no therapy (22.5% vs. 0%, p = 0.024). Fifty-one patients completed a post-clinic CCPKnow survey with a mean CCPKnow of 10.72 (SD 4.32). Participation in a pregnancy clinic improved reproductive knowledge in those with ulcerative colitis (p = 0.001), disease duration > 5 years (p = 0.017), those with at least a university education (p = 0.014) and those on IBD-related therapies (p = 0.026). CONCLUSIONS: Increased disease duration and preconception IBD-related therapy may be associated with increased pregnancy-related knowledge. A dedicated pregnancy clinic can improve reproductive knowledge in women with IBD.

Post-neonatal Outcomes of Infants Born to Women with Active Trimester One Inflammatory Bowel Disease: A Pilot Study.

BACKGROUND: Ulcerative colitis (UC) and Crohn's disease (CD) are chronic inflammatory bowel diseases (IBD) that affect women in their childbearing years. Early pregnancy flare-up negatively impacts obstetrical and perinatal outcomes, but the impact on infants is unclear. AIM: To determine whether active IBD disease activity is associated with adverse post-neonatal outcomes post-partum. METHODS: This is a single-center cohort study of women with IBD who underwent serial monitoring of post-neonatal outcomes post-partum. Infant outcomes were collected via self-filled questionnaires, including perinatal outcomes, APGAR scores, infant weights, heights, feeding habits and comorbidities within the first year of life. RESULTS: There was a total of 98 women with IBD and 78 live births throughout the study: 50 women were enrolled during trimester one alone and 49 were included into the current study. Among the 49 analyzed, 32 were in remission and 17 were in relapse during trimester one. Trimester one disease activity was associated with more adverse obstetrical outcomes including emergency C-sections and reduced 1-min APGAR scores. At follow-up, infants born to women with T1-flare had reduced weight-for-age Z scores and length-for-age Z scores up to 6 months of age. CONCLUSIONS: Active IBD during trimester one is correlated with adverse post-neonatal outcomes, particularly decreased infant weight and height up to 6 months of age. This suggests disease control in first trimester is essential for optimizing infant growth and post-neonatal outcomes.

Elevated IL-6 and IL-22 in Early Pregnancy Are Associated with Worse Disease Course in Women with Inflammatory Bowel Disease.

Inflammatory bowel diseases (IBD), including Ulcerative Colitis (UC) and Crohn's disease (CD), are inflammatory conditions of the intestinal tract that affect women in their reproductive years. Pregnancy affects Th1- and Th2-cytokines, but how these changes occur during pregnancy in IBD is unclear. We performed a longitudinal profiling of serum cytokines in a cohort of 11 healthy pregnant women and 76 pregnant women with IBD from the first trimester of pregnancy to the first 12 months post-partum. Participants were monitored for biochemical disease activity (C-reactive protein [CRP] and fecal calprotectin [FCP]) and clinical activities. Maternal cytokines were measured using ELISA. We identified changes in Th1 and Th17 cytokines throughout pregnancy in healthy pregnant women. During pregnancy, maternal serum cytokine expressions were influenced by IBD, disease activity, and medications. Active UC was associated with an elevation in IL-21, whereas active CD was associated with elevated IFN-γ, IL-6, and IL-21. Interestingly, T1 serum cytokine levels of IL-22 (>0.624 pg/mL) and IL-6 (>0.648 pg/mL) were associated with worse IBD disease activity throughout pregnancy in women with UC and CD, respectively. This shows serum cytokines in pregnancy differ by IBD, disease activity, and medications. We show for the first time that T1 IL-22 and IL-6 correlate with IBD disease course throughout pregnancy.

Active Margins, Plexitis, and Granulomas Increase Postoperative Crohn's Recurrence: Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Rates of postoperative Crohn's disease recurrence remain high, although the ability to predict this risk of recurrence remains limited. As such, we aimed to determine the association of histologic features at the time of resection with postoperative recurrence. METHODS: Electronic databases were searched through February 2020 for studies that reported risk of clinical, endoscopic, or surgical postoperative recurrence in patients with positive resection margins, plexitis, or granulomas in the index specimen. Pooled risk ratios (RRs) with 95% CIs were calculated for this risk in patients with and without these histologic features. RESULTS: Twenty-one studies (2481 patients) assessed positive resection margins, 10 studies (808 patients) assessed plexitis, and 19 studies (1777 patients) assessed granulomas. Positive resection margins increased the risk of clinical (RR, 1.26; 95% CI, 1.06-1.49; I2 = 41%) and surgical (RR, 1.87; 95% CI, 1.14-3.08; I2 = 71%) recurrence, with a trend toward endoscopic recurrence (RR, 1.56; 95% CI, 0.79-3.05; I2 = 85%). Granulomas increased the risk of clinical (RR, 1.31; 95% CI, 1.05-1.64; I2 = 36%) and endoscopic (RR, 1.37; 95% CI, 1.00-1.87; I2 = 49%) recurrence, with a trend toward surgical recurrence (RR, 1.58; 95% CI, 0.89-2.80; I2 = 75%). Plexitis increased the risk of endoscopic recurrence (RR, 1.31; 95% CI, 1.00-1.72; I2 = 20%), with a trend toward clinical recurrence (RR, 1.34; 95% CI, 0.95-1.91; I2 = 46%). CONCLUSIONS: Positive resection margins, granulomas, and plexitis are predictive of postoperative Crohn's disease recurrence and should be recorded at the time of index resection.

Efficacy of Hemospray (TC-325) in the Treatment of Gastrointestinal Bleeding: An Updated Systematic Review and Meta-analysis.

BACKGROUND: Hemospray (TC-325) is now approved for use in gastrointestinal bleeding. Data regarding their use pattern, efficacy, complications, and impact on clinical outcomes is limited. METHODS: Electronic search from relevant databases was conducted up to January 2019. Etiologies, therapy characteristics, hemostasis rates, rebleed rates, additional procedures, complications and mortality rates were extracted and pooled. RESULTS: Twenty-seven articles were included for analysis (n=1916). Pooled hemostasis was 94.5%. Pooled rebleed rate within 3 days was 9.9%, and within 30 days 17.6%. Pooled repeat Hemospray use was 13.6%. Radiology guided embolization was required with rate of 3.3% and surgery at rate of 4.7%. Rate of adverse events directly attributable to Hemospray was 0.7%. 30-day mortality was 11.8%. Comparison of conventional endoscopic therapy to Hemospray augmented therapy demonstrated that Hemospray therapy had increased immediate hemostasis [odds ratio (OR) 4.40]. There was no difference in rate of rebleeding at 8 days (OR 0.52) or overall mortality at 30 days (OR 0.53). Benign nonvariceal bleeds, malignant bleeds, and postprocedural bleeds had similar rates of hemostasis but rebleed rate at 30 days was less for postprocedural bleeding. CONCLUSIONS: The addition of Hemospray to conventional therapy appears to increase immediate hemostasis but does not decrease rebleeding or mortality. As such, the use of Hemospray will likely be limited to clinical situations requiring urgent, but temporary, hemostasis to bridge to more definitive therapy.

Systematic review and meta-analysis: Safety of vedolizumab during pregnancy in patients with inflammatory bowel disease.

BACKGROUND AND AIM: Vedolizumab is a novel monoclonal antibody used in patients with inflammatory bowel disease, often affecting women of child-bearing age. We aimed to compare maternal and fetal adverse outcomes in pregnancies of women with inflammatory bowel disease exposed to vedolizumab versus those on other treatment. METHODS: We performed a systematic literature search through December 2020 looking for studies including outcomes from pregnancies of female inflammatory bowel disease patients treated with vedolizumab. Our primary outcome was a composite of adverse pregnancy-related events in pregnancies of female patients on vedolizumab compared with those of disease-matched controls on other medication regimens. Events of interest included preterm births, early loss of pregnancy, late fetal death, elective termination of pregnancy, and congenital anomalies. RESULTS: Four studies were included in our review meeting criteria for our primary analysis. Compared with those with no vedolizumab exposure, pregnancies with vedolizumab exposure had an increase in overall adverse pregnancy-related outcomes (odds ratio [OR] 2.18, 95% confidence interval [CI], 1.52-3.13). The vedolizumab group also had increased preterm births (OR 2.16, 95% CI, 1.28-3.66), and early loss of pregnancies (OR 1.79, 95% CI, 1.06-3.01) but no difference in number of live births (OR 0.60, 95%CI, 0.36-1.00), or congenital malformations (OR 1.56, 95% CI, 0.56-4.37). CONCLUSIONS: Our systematic review highlights possible concern with the general safety of vedolizumab in pregnancy, as an increase in overall total unfavorable outcomes was observed. Premature births and early loss of pregnancy were also more prevalent in pregnant female patients on vedolizumab. It is possible these findings are confounded by disease activity, and further prospective cohort studies of vedolizumab and pregnancy outcomes are warranted.

Fecal Calprotectin May Predict Adverse Pregnancy-Related Outcomes in Patients with Inflammatory Bowel Disease.

BACKGROUND: The role of fecal calprotectin in predicting pregnancy-related outcomes in inflammatory bowel disease (IBD) remains unknown. AIM: To determine whether increased fecal calprotectin during pregnancy is associated with adverse pregnancy outcomes in IBD. METHODS: This is a multicenter cohort study of women with IBD who underwent fecal calprotectin monitoring during pregnancy. Fecal calprotectin levels were stratified by trimester, and adverse pregnancy-related outcomes were recorded. The Mann-Whitney U test assessed differences between continuous variables, whereas categorical variables were compared using the Chi-squared test. RESULTS: Eighty-five women with IBD were included. First trimester fecal calprotectin was higher in patients who underwent emergency Cesarean birth compared to those who had a vaginal delivery (503 ug/g, IQR 1554.3 ug/g vs. 130 ug/g, IQR 482 ug/g, p = .030, respectively) and in those who delivered infants with low birth weight compared to normal birth weight (1511 ug/g, IQR 579 ug/g vs. 168 ug/g, IQR 413 ug/g, p = .049, respectively). Third trimester fecal calprotectin was higher in those with non-elective induction of labor (334.5 ug/g, IQR 1411.0 ug/g) compared to those with spontaneous delivery (116.5 ug/g, IQR 227.1 ug/g) (p = .025). Those with a fecal calprotectin ≥ 250 ug/g in the second trimester had an increased incidence of infants with low birth weight (35.3% vs. 3.8%) (p = .049), whereas those with a fecal calprotectin ≥ 250 ug/g in the third trimester had an increased incidence of non-elective induction of labor (43.8% vs. 10.3%, p = .030). CONCLUSIONS: Fecal calprotectin may be a useful noninvasive marker to predict adverse pregnancy-related outcomes in patients with IBD.

Noninvasive Methods For Assessing Inflammatory Bowel Disease Activity in Pregnancy: A Systematic Review.

Active inflammatory bowel disease (IBD) may increase the risk of adverse outcomes during pregnancy. Our aim was to systematically review the role of noninvasive fecal tests, such as fecal calprotectin (FCP) and lactoferrin (FL), and laboratory tests including C-reactive protein (CRP), hemoglobin, and albumin in the assessment of IBD during pregnancy. A systematic search of electronic databases was performed through October 2018 for studies assessing the utility of fecal and laboratory tests in predicting IBD activity in pregnant patients. Active disease was defined based on routinely used clinical criteria such as the Harvey-Bradshaw Index or Mayo score for ulcerative colitis. Noninvasive test levels were stratified by the presence of active disease and by gestational period (preconception, first trimester, second trimester, and third trimester). Thirteen studies were included. Both FCP and FL levels were significantly higher in pregnant patients with IBD compared with those without IBD. FCP levels were also significantly higher in patients with active disease compared with those with the inactive disease during all gestational periods. Furthermore, 3 studies demonstrated no consistent correlation with serum CRP and active IBD during pregnancy. Similarly, serum albumin and hemoglobin levels did not correlate with disease activity in pregnant patients with IBD. Given the lack of high-quality evidence, only FCP appears to correlate with IBD activity in all gestational periods of pregnancy. The utility of the other noninvasive tests such as serum CRP, hemoglobin, and albumin remains to be determined in this population.

Strategies to Optimize Anti-tumor Necrosis Factor Therapy for Perianal Fistulizing Crohn's Disease: A Systematic Review.

Tumor necrosis factor (TNF) antagonists are considered the cornerstone therapy for fistulizing perianal Crohn's disease (PCD), yet a substantial proportion of patients fail to achieve healing. Therefore, we reviewed the evidence for strategies to enhance the efficacy of TNF antagonists for PCD. A systematic search of electronic databases through July 2018 was performed to identify studies that assessed the effectiveness of TNF antagonists combined with another medical or surgical intervention for PCD; or assessed the association between anti-TNF serum concentrations and fistula healing. Twelve studies compared anti-TNF therapy alone versus a combined approach: four with surgery, three with antibiotics, and five with immunomodulators. Only two studies, both with antibiotics, were rated high quality. The addition of antibiotics to anti-TNF therapy resulted in significantly higher rates of fistula response and healing in one study, and a trend toward reduction in fistula drainage in the other. Three of four studies found higher rates of fistula healing when surgery was combined with TNF antagonists. In contrast, one of five studies found a trend toward higher rates of fistula healing in patients treated concomitantly with immunomodulators. Five observational studies assessed the association between anti-TNF concentration and fistula healing. Higher infliximab serum concentrations were consistently associated with fistula healing. In conclusion, few high-quality studies assessing strategies to optimize anti-TNF therapy for PCD exist. Although antibiotics, possibly surgery, and higher serum infliximab concentrations appear to improve fistula healing, future prospective studies are needed to determine the optimal treatment strategy.

Comparison of clinical outcomes between variceal and non-variceal gastrointestinal bleeding in patients with cirrhosis.

BACKGROUND AND AIM: Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS), and 30-day readmission have yet to be determined. As such, the study aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB. METHODS: This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016. AVB was defined as the presence of varices on endoscopy with high-risk stigmata such as cherry-red spots. Mortality, intensive care unit admission, hospital LOS, and 30-day hospital readmission were recorded and compared among patients with AVB and NVB. RESULTS: A total of 116 patients with cirrhosis were included, 73 with AVB and 43 with NVB. Patients with NVB were older than those with AVB (60.4 ± 11.1 vs 55.0 ± 9.5, P = 0.006) whereas patients with AVB were more likely to have known esophageal varices (64.4% vs 37.2%, P = 0.007). Patients with AVB and NVB had similar mortality (15.1% vs 9.3%, P = 0.57), hospital LOS (4.9, interquartile range: 3.6-6.9 days vs 5.0, interquartile range: 2.7-8.3 days), and 30-day readmission rates (19.2% vs 30.2%, P = 0.18). Severity of clinical presentation was associated with increased LOS and overall mortality, including the need for intensive care unit admission, but these were not associated with 30-day readmission rates. CONCLUSION: There were no differences in clinical outcomes, including mortality, in cirrhotic patients admitted with AVB and NVB.

Corticosteroids and Thiopurines, But Not Tumor Necrosis Factor Antagonists, are Associated With Cytomegalovirus Reactivation in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: The association between cytomegalovirus (CMV) reactivation and individual immunosuppressive agents in inflammatory bowel disease (IBD) has not been clearly defined. Therefore, we performed a systematic review and meta-analysis to assess this association. METHODS: Multiple electronic databases were searched systematically through July 2015 for observational studies reporting CMV reactivation (based on serum-based or tissue-based tests) in IBD patients stratified by medication exposure. We estimated summary odds ratios (ORs) and 95% confidence intervals (CI) using random-effects model. Study quality was assessed using the Newcastle-Ottawa scale. RESULTS: Sixteen observational studies were identified. As compared with nonexposed patients, exposure to corticosteroids (CS) (12 studies, 1180 patients, 52.3% exposed; OR, 2.05; 95% CI, 1.40-2.99) and thiopurines (14 studies, 1273 patients, 24.1% exposed; OR, 1.56; 95% CI, 1.01-2.39) was associated with increased risk of CMV reactivation. In contrast, as compared with patients not exposed to tumor necrosis factor (TNF) antagonists, exposure to TNF antagonists was not associated with an increased risk of CMV reactivation (7 studies, 818 patients, 18.5% exposed; OR, 1.44; 95% CI, 0.93-2.24). The results remained stable for CS and thiopurines when the analysis was limited to hospitalized patients, and by a tissue-based diagnosis. Studies were limited in the ability to assess the impact of concomitant immunosuppressive therapy, duration of medication exposure, and disease severity. CONCLUSIONS: On the basis of 16 observational studies, exposure to CS or thiopurines, but not TNF antagonists, was associated with an increased risk of CMV reactivation in IBD patients.

The prevalence of squamous cell carcinoma in different sites of oral cavity at our Rural Health Care Centre in Loni, Maharashtra - a retrospective 10-year study.

AIM OF THE STUDY: Oral cancer ranks in the top three of all cancers in India and is quickly becoming a global health priority. More than 90% of oral and oropharyngeal cancers are squamous cell carcinoma. The purpose of this study was to document its incidence depending upon the involvement of different sites of oral cavity, and its variation with age and gender. MATERIAL AND METHODS: Histopathologically proven oral squamous cell carcinoma cases were collected from the department of oral and maxillofacial surgery RDC, PIMS. The cases were systematically grouped under three headings: anatomical sub-site of oral cavity, age group, and gender, which were analysed to calculate the prevalence of oral cancer. The study was undertaken after obtaining approval from the institutional Ethical Committee board. RESULTS: Among the different sites of oral cavity, the highest incidence (31.47%) of oral squamous cell carcinoma was seen for buccal mucosa in our study. The most affected age group (39.50%) were patients above 50 years old, predominantly involving males. CONCLUSIONS: The population in this study were mostly from remote areas, among which a high rate of occurrence of oral cancer was encountered because the people were of low socio-economic class, had a casual attitude towards their health, high rate of tobacco consumption, and limited health care facilities. This study provides valuable data of the prevalence of oral cancer among the rural population.

Intestinal Failure: Adaptation, Rehabilitation, and Transplantation.

Intestinal failure (IF) is a state in which the nutritional demands are not met by the gastrointestinal absorptive surface. A majority of IF cases are associated with short-bowel syndrome, which is a result of malabsorption after significant intestinal resection for numerous reasons, some of which include Crohn's disease, vascular thrombosis, and radiation enteritis. IF can also be caused by obstruction, dysmotility, and congenital defects. Recognition and management of IF can be challenging, given the complex nature of this condition. This review discusses the management of IF with a focus on intestinal rehabilitation, parenteral nutrition, and transplantation.

Gastrointestinal Manifestations, Malnutrition, and Role of Enteral and Parenteral Nutrition in Patients With Scleroderma.

Scleroderma (systemic sclerosis) is an autoimmune disease that can affect multiple organ systems. Gastrointestinal (GI) involvement is the most common organ system involved in scleroderma. Complications of GI involvement including gastroesophageal reflux disease, small intestinal bacterial overgrowth, and chronic intestinal pseudoobstruction secondary to extensive fibrosis may lead to nutritional deficiencies in these patients. Here, we discuss pathophysiology, progression of GI manifestations, and malnutrition secondary to scleroderma, and the use of enteral and parenteral nutrition to reverse severe nutritional deficiencies. Increased mortality in patients with concurrent malnutrition in systemic sclerosis, as well as the refractory nature of this malnutrition to pharmacologic therapies compels clinicians to provide novel and more invasive interventions in reversing these nutritional deficiencies. Enteral and parenteral nutrition have important implications for patients who are severely malnourished or have compromised GI function as they are relatively safe and have substantial retrospective evidence of success. Increased awareness of these therapeutic options is important when treating scleroderma-associated malnutrition.

Inflammatory Bowel Disease and Breastfeeding: A Narrative Review.

Inflammatory bowel disease (IBD) frequently affects women of childbearing age who may consider breastfeeding. Although breastfeeding has numerous benefits, there remain concerns regarding the safety of breastfeeding among women with IBD. Breastfeeding is important in developing the immune system of infants and has been shown to protect against the development of IBD. The risk of developing an increase in disease activity postpartum is the same regardless of breastfeeding status. Most IBD medications are also considered safe in breastfeeding and have no major risks to infants. Despite this, breastfeeding rates remain low among women with IBD, mostly due to concerns about the safety of IBD therapy with breastfeeding. Many women self-discontinue their IBD medications to breastfeed, and there is often uncertainty among health professionals to make recommendations about therapy. Dedicated IBD clinics can greatly support mothers during pregnancy and breastfeeding periods to enhance their knowledge, optimize their medication adherence, and improve their postpartum outcomes. This review aims to provide the most recent evidence-based literature regarding the safety of breastfeeding in women with IBD and the current recommendations about medical therapies with breastfeeding.

The literature supports breastfeeding as a generally safe and beneficial practice for mothers with inflammatory bowel disease, though misconceptions around the safety of this practice persist. Multidisciplinary care models are essential for improving outcomes for women with inflammatory bowel disease who are breastfeeding.

Biomechanical analysis and comparison between 'Zeta' miniplate design and conventional miniplate system for fixation of fracture segments in transition zone of parasymphysis body region of mandible - an in vitro study.

The parasymphysis area of the mandible is highly dynamic because it is subjected to both occlusal and muscular forces. As a result, the fractures in this transition zone have a special pattern, posing a challenge for surgeons whether to use one miniplate versus two miniplates, as per Champy's recommendations. The commonest complication resulting to treat this area is mental nerve paraesthesia due to the dissection and stretching of the nerve. Hence, an in vitro research study of a newly designed 'Zeta' miniplate is performed, to evaluate the biomechanical behaviour using finite element (FE) analysis and biomechanical analysis along with a comparison study with the conventional miniplate configurations. The results showed that the Zeta miniplate produces the lowest stresses 17.511 MPa and the least total structural deformation of 0.0011 mm after applying the maximum occlusal bite force. On application of torsional load, total structural deformation was 0.0004 mm and von Mises (VM) stress value was 0.24 MPa which was lowest when compared with the two miniplate system. Hence, the newly developed Zeta miniplate is superior in terms of stability. Another benefit of its design is that it helps in preventing mental nerve paraesthesia and tooth root damage while fixing and stabilising the fractured bony segments.
