Variation in Testing for and Incidence of Celiac Autoimmunity in Canada: A Population-Based Study.

BACKGROUND & AIMS: The incidence of biopsy-confirmed celiac disease has increased. However, few studies have explored the incidence of celiac autoimmunity based on positive serology results. METHODS: A population-based cohort study assessed testing of tissue transglutaminase antibodies (tTG-IgA) in Alberta from 2012 to 2020. After excluding prevalent cases, incident celiac autoimmunity was defined as the first positive tTG-IgA result between 2015 and 2020. Testing and incidence rates for celiac autoimmunity were calculated per 1000 and 100,000 person-years, respectively. Incidence rate ratios (IRRs) were calculated to identify differences by demographic and regional factors. Average annual percent changes (AAPCs) assessed trends over time. RESULTS: The testing rate of tTG-IgA was 20.2 per 1000 person-years and remained stable from 2012 to 2020 (AAPC, 1.2%; 95% confidence interval [CI], -0.5 to 2.9). Testing was higher in female patients (IRR, 1.66; 95% CI, 1.65-1.66), those living in metropolitan areas (IRR, 1.39; 95% CI, 1.38-1.40), and in areas of lower socioeconomic deprivation (lowest compared to highest IRR, 1.24; 95% CI, 1.23-1.25). Incidence of celiac autoimmunity was 33.8 per 100,000 person-years and increased from 2015 to 2020 (AAPC, 6.2%; 95% CI, 3.1-9.5). Among those with tTG-IgA results ≥10 times the upper limit of normal, the incidence was 12.9 per 100,000 person-years. The incidence of celiac autoimmunity was higher in metropolitan settings (IRR, 1.28; 95% CI, 1.21-1.35) and in the least socioeconomically deprived areas compared to the highest (IRR, 1.22; 95% CI, 1.14-1.32). CONCLUSIONS: Incidence of celiac autoimmunity is high and increasing, despite stable testing rates. Variation in testing patterns may lead to underreporting the incidence of celiac autoimmunity in nonmetropolitan areas and more socioeconomically deprived neighborhoods.

Anti-Inflammatory Diet Prevents Subclinical Colonic Inflammation and Alters Metabolomic Profile of Ulcerative Colitis Patients in Clinical Remission.

A relationship between ulcerative colitis (UC) and diet has been shown in epidemiological and experimental studies. In a 6-month, open-label, randomized, placebo-controlled trial, adult UC patients in clinical remission were randomized to either an "Anti-inflammatory Diet (AID)" or "Canada's Food Guide (CFG)". Menu plans in the AID were designed to increase the dietary intake of dietary fiber, probiotics, antioxidants, and omega-3 fatty acids and to decrease the intake of red meat, processed meat, and added sugar. Stool was collected for fecal calprotectin (FCP) and microbial analysis. Metabolomic analysis was performed on urine, serum, and stool samples at the baseline and study endpoint. In this study, 53 patients were randomized. Five (19.2%) patients in the AID and 8 (29.6%) patients in the CFG experienced a clinical relapse. The subclinical response to the intervention (defined as FCP < 150 µg/g at the endpoint) was significantly higher in the AID group (69.2 vs. 37.0%, p = 0.02). The patients in the AID group had an increased intake of zinc, phosphorus, selenium, yogurt, and seafood versus the control group. Adherence to the AID was associated with significant changes in the metabolome, with decreased fecal acetone and xanthine levels along with increased fecal taurine and urinary carnosine and p-hydroxybenzoic acid levels. The AID subjects also had increases in fecal Bifidobacteriaceae, Lachnospiraceae, and Ruminococcaceae. In this study, we found thatdietary modifications involving the increased intake of anti-inflammatory foods combined with a decreased intake of pro-inflammatory foods were associated with metabolic and microbial changes in UC patients in clinical remission and were effective in preventing subclinical inflammation.

Nurse-Led, Shared Medical Appointments for Common Gastrointestinal Conditions-Improving Outcomes Through Collaboration With Primary Care in the Medical Home: A Prospective Observational Study.

BACKGROUND: Gastroesophageal reflux disease (GERD), dyspepsia and irritable bowel syndrome (IBS) are common gastrointestinal disorders accounting for a significant demand for specialty care. The aim of this study was to evaluate safety, access and outcomes of patients assessed by a nurse-led, shared medical appointment. METHODS: This prospective observational study utilized a sample of 770 patients referred to a gastroenterology Central Access and Triage for routine GERD, dyspepsia or IBS from 2011 to 2014. Patient demographics, clinical indication, frequency and outcomes of endoscopy, quality of life, wait times and long-term outcomes (>2 years) were compared between 411 patients assigned to a nurse-led, shared medical appointment and 359 patients assigned to clinic for a gastroenterology physician consultation. RESULTS: The nurse-led, shared medical appointment pathway compared with usual care pathway had shorter median wait times (12.6 weeks versus 137.1 weeks, P < 0.0001), fewer endoscopic exams (50.9% versus 76.3%, P < 0.0001), less gastroenterology re-referrals (4.6% versus 15.6%, P < 0.0001), and reduced visits to the emergency department (6.1% versus 12.0%, P = 0.004). After two years of follow-up, outcomes were no different between the pathways. CONCLUSIONS: Patients with GERD, IBS or dyspepsia who attend the nurse-led, shared medical appointment have improved access to care and reduced resource utilization without increased risk of significant gastrointestinal outcomes after two years of follow-up.

Adversity in childhood and depression in pregnancy.

Adverse childhood experiences (ACEs) have been found to be associated with various health conditions; however, there is dearth of evidence on the relationship between ACEs and prenatal depression. This study was conducted to determine the association between overall ACE score and prenatal depression symptoms, assess the moderating effect of social support and partner support on this relationship, and determine the association between individual ACE scores and prenatal depression. A secondary analysis was conducted of data from an RCT that assessed the feasibility of e-screening for maternal mental health among 636 pregnant women recruited from antenatal clinics. Two logistic regression models were built to reach our objectives. Over 80% of the participants were older than 25 years and had education beyond high school. Eighteen percent of the women had an ACE score of four or more. Univariable analysis found a 2.5-fold increase in the odds of prenatal depression for women with an ACEs score of ≥ 4. When examining the overall ACE score, lack of social support during pregnancy [AOR = 4.16; 95%CI (2.10-10.35)] and partner's relationship [AOR = 2.23; 95%CI (1.12-4.44)] were associated with prenatal depression while among the individual ACE scores, living with a person who went to prison was found to be associated with prenatal depression even when controlled for all variables. No moderating effect was found. These findings suggest for the improvement of partner's relationship and provision of social support before women conceive, in order to mitigate the effect of these adversities.

Burden of disease from Helicobacter pylori infection in western Canadian Arctic communities.

BACKGROUND: Indigenous communities across the circumpolar north have elevated H. pylori (Hp) prevalence and stomach cancer incidence. We aimed to describe the Hp-associated disease burden among western Canadian Arctic participants in community-driven projects that address concerns about health risks from Hp infection. METHODS: During 2008-2013, participants underwent Hp screening by urea breath test and gastroscopy with gastric biopsies. We estimated Hp prevalence and prevalence by Hp status of endoscopic and histopathologic diagnoses. RESULTS: Among 878 participants with Hp status data, Hp prevalence was: 62% overall; 66% in 740 Indigenous participants; 22% in 77 non-Indigenous participants (61 participants did not disclose ethnicity); 45% at 0-14 years old, 69% at 15-34 years old, and 61% at 35-96 years old. Among 309 participants examined endoscopically, visible mucosal lesions were more frequent in the stomach than the duodenum: the gastric to duodenal ratio was 2 for inflammation, 8 for erosions, and 3 for ulcers. Pathological examination in 308 participants with gastric biopsies revealed normal gastric mucosa in 1 of 224 Hp-positive participants and 77% (65/84) of Hp-negative participants with sharp contrasts in the prevalence of abnormalities between Hp-positive and Hp-negative participants, respectively: moderate-severe active gastritis in 50 and 0%; moderate-severe chronic gastritis in 91 and 1%; atrophic gastritis in 43 and 0%; intestinal metaplasia in 17 and 5%. CONCLUSIONS: The observed pattern of disease is consistent with increased risk of stomach cancer and reflects substantial inequity in the Hp-associated disease burden in western Arctic Canadian hamlets relative to most North American settings. This research adds to evidence that demonstrates the need for interventions aimed at reducing health risks from Hp infection in Indigenous Arctic communities.

Internet-based interpersonal psychotherapy for stress, anxiety, and depression in prenatal women: study protocol for a pilot randomized controlled trial.

BACKGROUND: Psychological distress, defined as depression, anxiety and perceived stress, during pregnancy is common, with 15-25% of women experiencing clinically significant levels of such distress. Despite the far-reaching impact of prenatal psychological distress on mothers and their children, and that women are receptive to screening, few providers routinely screen for prenatal psychological distress and less than one in five women will receive the mental health care that they require. There is a lack of certainty regarding the most effective treatments for prenatal psychological distress. No online interpersonal psychotherapy (IPT) trials have been conducted that focus on improving psychological distress in prenatal women. The purpose of this pilot randomized controlled trial is to evaluate the perspectives of pregnant women on the feasibility and acceptability of online IPT (e-IPT) delivered during pregnancy. METHODS: A pilot randomized controlled trial design with repeated measures will evaluate the feasibility and acceptability of e-IPT for pregnant women compared to routine prenatal care. Qualitative interviews with 15-30 individuals in the intervention group will provide further data on the feasibility and acceptability of the intervention. Assessment of feasibility will include the ease of accessing and completing the intervention. Women will also be asked about what barriers there were to starting and completing the e-IPT. Assessment of acceptability will inquire about the perception of women regarding the intervention and its various features. A sample size of 160 consenting pregnant women aged 18 years and older will be enrolled and randomized into the experimental (e-IPT) or control (routine care) condition. The secondary outcome measures include: depression, anxiety and stress symptoms; self-efficacy; self-mastery; self-esteem; relationship quality (spouse, immediate family members); coping; and resilience. All participants will complete the aforementioned measures at baseline during pregnancy (T1), 3 months postrandomization (T2), at 8 months of pregnancy (T3), and 3 months postpartum (T4). DISCUSSION: The results of this pilot randomized controlled trial will provide data on the feasibility and acceptability of the intervention and identify necessary adaptations. This study will allow for optimization of full trial processes and inform the evaluation strategy, including sample size calculations for the full randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01901796. Registered on 18 December 2014.

Comparison of Urdu Versions of the Resilience Scale and the Resilience Scale for Adults.

BACKGROUND AND PURPOSE: Several methodological challenges are associated with measuring resilience in women. This study compares the 14-item Resilience Scale (RS-14) and the Resilience Scale for Adults (RSA) in a community sample of women. METHODS: Data were collected from 120 women residing in low socioeconomic areas of Karachi, Pakistan. Construct validity, internal consistency, and responsiveness were calculated. RESULTS: Both scales demonstrated satisfactory psychometric characteristics. The total RS-14 score was significantly associated with all subscales of the RSA. However, two items of the RS-14 did not show any association with any of the subscales of the RSA. Medium effect size was noted on the "structured style"subscale of the RSA. CONCLUSION: Differences between the scales concluded that the Urdu version the of RSA yielded improved results in this sample.

Social support intervention to promote resilience and quality of life in women living in Karachi, Pakistan: a randomized controlled trial.

OBJECTIVES: This study tested the efficacy of a 6-week social support intervention for enhancing resilience and quality of life among women living in low socioeconomic areas of Karachi, Pakistan. METHODS: One hundred and twenty women were randomly allocated to the intervention (n = 60) or control group (n = 60). Women in the intervention group attended a 6-week social support program, while those in the control group attended a single mental health awareness session. Outcome variables were measured via the resilience scale-14 item (RS-14), the resilience scale for adults (RSA), and World Health Organization quality of life brief scale (WHOQOL-BREF). RESULTS: Compared to participants in the control group, women in the intervention group reported improvements in resilience measured by RS-14 (p = 0.022) and the structured style subscale of the RSA (p = 0.043). A medium effect size was also measured on the structured style subscale (d = 0.6, 95% CI = 0.62874, 2.57126). No significant findings were noted on QOL scores. CONCLUSIONS: Community-based social support interventions are a gender-sensitive-, culturally appropriate-, and resource-sparing approach to promote women's resilience and improve their mental health.

The Safety and Efficacy of Single-Operator Cholangioscopy in the Treatment of Difficult Common Bile Duct Stones after Failed Conventional ERCP.

BACKGROUND: Common bile duct (CBD) stones are extracted with a basket or balloon during ERCP with sphincterotomy. However, some stones are difficult to extract by conventional means. Cholangioscopy with lithotripsy is a modality to treat these difficult stones. We describe the clinical efficacy of single-operator per oral cholangioscopy (SOPOC) for difficult stones and discuss cost savings by avoiding surgical intervention. METHODS: Retrospective chart review was performed for all patients referred for difficult CBD stones. Clinical success was defined as clearing the duct of all stones. The cost of cholangioscopy (in $CDN) was calculated by adding all costs associated with the procedure(s), surgery, hospital stay or treatment of adverse events. This cost was compared with the projected cost of surgical bile duct exploration. RESULTS: A total of 51 patients (35 female) with a mean age of 66 years underwent 58 SOPOC procedures. Median procedure time was 67 minutes (95% CI, 61.5-73.5). The CBD was successfully cleared in 47 of 51 patients (93%). Minor adverse events were seen in seven patients (14%). The actual average per procedure cost was $4555±$2647. This compares with a projected cost of $7766 and $6175 for open and laparoscopic bile duct exploration, with a cost-per-case saving of $3210 and $1619, respectively. CONCLUSION: SOPOC with lithotripsy is highly effective and safe for the treatment of difficult common bile duct stones. In addition, significant cost savings may be realized by avoiding surgical bile duct exploration.

Patient-ly Waiting: A Review of Patient-Centered Access to Inflammatory Bowel Disease Care in Canada.

Canada has one of the highest prevalence estimates of inflammatory bowel disease (IBD) in the world. Like other chronic illnesses, access to specialist care is required for disease management. Traditionally, access to care is evaluated through wait times (actual access); however, new patient-oriented definitions of access (perceived access) highlight other equally important facets of access to care (e.g., appropriateness). Aim: How does access to gastroenterology speciality care influence disease-related outcomes for IBD patients in Canada? A comprehensive literature review was undertaken. Cochrane, PubMed and CINHAL databases were searched for peer-reviewed English language articles published between 2006 and 2016. Inclusion/exclusion criteria focussed on access to IBD care in Canada. Included articles were classified using Levesque et al.'s patient-centered access framework (e.g., affordability, accessibility, appropriateness, acceptability, availability and accommodation). Eight articles were found, including six which addressed patient-centered access. Most of the articles addressed issues of availability (e.g., wait times), appropriateness and affordability. Only one article addressed approachability and acceptability of IBD care. All articles emphasized a need for greater patient-centered measures (e.g., multidisciplinary clinics) with a goal to improve patient access and, ultimately, patient outcomes. Understanding patient-centered access to IBD care is important for managing IBD and improving patient outcomes. Literature examining access to gastroenterology services is limited. Increased investment in patient-oriented research should be made to better understand the relationship between access to specialist care and patient outcomes.

The Toronto Consensus for the Treatment of Helicobacter pylori Infection in Adults.

BACKGROUND & AIMS: Helicobacter pylori infection is increasingly difficult to treat. The purpose of these consensus statements is to provide a review of the literature and specific, updated recommendations for eradication therapy in adults. METHODS: A systematic literature search identified studies on H pylori treatment. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an online platform, finalized, and voted on by an international working group of specialists chosen by the Canadian Association of Gastroenterology. RESULTS: Because of increasing failure of therapy, the consensus group strongly recommends that all H pylori eradication regimens now be given for 14 days. Recommended first-line strategies include concomitant nonbismuth quadruple therapy (proton pump inhibitor [PPI] + amoxicillin + metronidazole + clarithromycin [PAMC]) and traditional bismuth quadruple therapy (PPI + bismuth + metronidazole + tetracycline [PBMT]). PPI triple therapy (PPI + clarithromycin + either amoxicillin or metronidazole) is restricted to areas with known low clarithromycin resistance or high eradication success with these regimens. Recommended rescue therapies include PBMT and levofloxacin-containing therapy (PPI + amoxicillin + levofloxacin). Rifabutin regimens should be restricted to patients who have failed to respond to at least 3 prior options. CONCLUSIONS: Optimal treatment of H pylori infection requires careful attention to local antibiotic resistance and eradication patterns. The quadruple therapies PAMC or PBMT should play a more prominent role in eradication of H pylori infection, and all treatments should be given for 14 days.

Upper gastrointestinal bleeding due to peptic ulcer disease is not associated with air pollution: a case-crossover study.

BACKGROUND: Recent studies have demonstrated an association between short-term elevations in air pollution and an increased risk of exacerbating gastrointestinal disease. The objective of the study was to evaluate if day-to-day increases in air pollution concentrations were positively associated with upper gastrointestinal bleeding (UGIB) secondary to peptic ulcer disease (PUD). METHODS: A time-stratified case-crossover study design was used. Adults presenting to hospitals with their first UGIB secondary to PUD from 2004-2010 were identified using administrative databases from Calgary (n = 1374; discovery cohort) and Edmonton (n = 1159; replication cohort). Daily concentrations of ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and particulate matter (PM10 and PM2.5) were estimated in these two cities. Conditional logistic regression models were employed, adjusting for temperature and humidity. Odds ratios (OR) with 95 % confidence intervals (CI) were expressed relative to an interquartile range increase in the concentration of each pollutant. RESULTS: No statistically significant associations were observed for any of the individual pollutants based on same-day, or 1-day lag effects within the Calgary discovery cohort. When the air pollution exposures were assessed as 3-, 5-, and 7-day averages, some pollutants were inversely associated with UGIB in the discovery cohort; for example, 5-day averages of nitrogen dioxide (OR = 0.68; 95 % CI: 0.53-0.88), and particulate matter <2.5 µm (OR = 0.75; 95 % CI: 0.61-0.90). However, these findings could not be reproduced in the replication cohort. CONCLUSION: Our findings suggest that short-term elevations in the level of ambient air pollutants does not increase the incidence of UGIB secondary to PUD.

Barriers and facilitators of mental health screening in pregnancy.

BACKGROUND: Access to mental health services during pregnancy is most commonly mobilized through formal mental health screening. However, few studies to date have identified barriers and facilitators that affect pregnant women's responses to mental health screening. The objective was to identify barriers and facilitators that influence pregnant women's responses to the screening process and factors associated with their identification. METHODS: This multi-site, cross-sectional survey recruited pregnant women >16 years of age who spoke/read English in Alberta, Canada. Main outcomes were barriers and facilitators of mental health screening. Descriptive statistics were generated to identify the most common barriers and facilitators and multivariable logistic regression models were conducted to determine factors associated with barriers and facilitators. RESULTS: Study participation rate was 92% (460/500). Women's most common barriers were: significant others normalizing their emotional difficulties; desiring to handle mental health problems on their own; preferring to discuss feelings with significant others; and not knowing what emotions were 'normal'. Women who identified these barriers were more likely not to have been treated previously for mental illness, were primiparous, and could not be completely honest with their provider. Main facilitators were provider characteristics (sensitive, interested), reassurance that mental healthcare is a part of routine prenatal care, hearing that other women have emotional problems during pregnancy and knowing that help was available. LIMITATIONS: The sample comprised largely Caucasian, well-educated, and partnered women, which limits generalizability of the findings. CONCLUSIONS: Personal and stigma-related barriers influence pregnant women's responses to mental health screening. Efforts to minimize barriers and enhance facilitators should be explored as potential strategies for optimizing prenatal mental health screening.

Upper-gastrointestinal bleeding secondary to peptic ulcer disease: incidence and outcomes.

AIM: To evaluate the incidence, surgery, mortality, and readmission of upper gastrointestinal bleeding (UGIB) secondary to peptic ulcer disease (PUD). METHODS: Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta, Canada from 2004 to 2010 (n = 7079) using the International Classification of Diseases Codes (ICD-10). A subset of the data was validated using endoscopy reports. Positive predictive value and sensitivity with 95% confidence intervals (CI) were calculated. Incidence of UGIB secondary to PUD was calculated. Logistic regression was used to evaluate surgery, in-hospital mortality, and 30-d readmission to hospital with recurrent UGIB secondary to PUD. Co-variants accounted for in our logistic regression model included: age, sex, area of residence (i.e., urban vs rural), number of Charlson comorbidities, presence of perforated PUD, undergoing upper endoscopy, year of admission, and interventional radiological attempt at controlling bleeding. A subgroup analysis (n = 6356) compared outcomes of patients with gastric ulcers to those with duodenal ulcers. Adjusted estimates are presented as odds ratios (OR) with 95%CI. RESULTS: The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were 85.2% (95%CI: 80.2%-90.2%) and 77.1% (95%CI: 69.1%-85.2%), respectively. The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per 100000. Overall risk of surgery, in-hospital mortality, and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%, 8.5%, and 4.7%, respectively. Interventional radiology to control bleeding was performed in 0.6% of patients and 76% of these patients avoided surgical intervention. Thirty-day readmission significantly increased from 3.1% in 2004 to 5.2% in 2010 (OR = 1.07; 95%CI: 1.01-1.14). Rural residents (OR rural vs urban: 2.35; 95%CI: 1.83-3.01) and older individuals (OR ≥ 65 vs < 65: 1.57; 95%CI: 1.21-2.04) were at higher odds of being readmitted to hospital. Patients with duodenal ulcers had higher odds of dying (OR = 1.27; 95%CI: 1.05-1.53), requiring surgery (OR = 1.73; 95%CI: 1.34-2.23), and being readmitted to hospital (OR = 1.54; 95%CI: 1.19-1.99) when compared to gastric ulcers. CONCLUSION: UGIB secondary to PUD, particularly duodenal ulcers, was associated with significant morbidity and mortality. Early readmissions increased over time and occurred more commonly in rural areas.
