Abstract
BACKGROUND The incidence of inflammatory bowel disease (IBD) is rising worldwide, though the differences in health care utilization among different races and ethnicities remains uncertain. We aimed to better define this through a systematic review and meta-analysis. METHODS We explored the impact of race or ethnicity on the likelihood of needing an IBD-related surgery, hospitalization, and emergency department visit. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated with I2 values reporting heterogeneity. Differences in IBD phenotype and treatment between racial and ethnic groups of IBD were reported. RESULTS Fifty-eight studies were included. Compared with White patients, Black patients were less likely to undergo a Crohn's disease (CD; OR, 0.69; 95% CI, 0.50-0.95; I2 = 68.0%) or ulcerative colitis (OR, 0.58; 95% CI, 0.40-0.83; I2 = 85.0%) surgery, more likely to have an IBD-hospitalization (OR, 1.54; 95% CI, 1.06-2.24; I2 = 77.0%), and more likely to visit the emergency department (OR, 1.74; 95% CI, 1.32-2.30; I2 = 0%). There were no significant differences in disease behavior or biologic exposure between Black and White patients. Hispanic patients were less likely to undergo a CD surgery (OR, 0.57; 95% CI, 0.48-0.68; I2 = 0%) but more likely to be hospitalized (OR, 1.38; 95% CI, 1.01-1.88; I2 = 37.0%) compared with White patients. There were no differences in health care utilization between White and Asian or South Asian patients with IBD. CONCLUSIONS There remain significant differences in health care utilization among races and ethnicities in IBD. Future research is required to determine factors behind these differences to achieve equitable care for persons living with IBD.

Abstract
Approximately one out of every 88 seniors has inflammatory bowel disease (IBD), and this is expected to increase in the future. They are more likely to have left-sided disease in ulcerative colitis, and isolated colonic disease in Crohn's disease; perianal disease is less common. Other common diagnoses in the elderly must also be considered when they initially present to a healthcare provider. Treatment of the elderly is similar to younger persons with IBD, though considerations of the increased risk of infections and malignancy must be considered when using immune modulating drugs. Whether anti-TNF therapies increase the risk of infections is not definitive, though newer biologics, including vedolizumab and ustekinumab, are thought to be safer with lower risk of adverse events. Polypharmacy and frailty are other considerations in the elderly when choosing a treatment, as frailty is associated with worse outcomes. Costs for IBD-related hospitalizations are higher in the elderly compared with younger persons. When elderly persons with IBD are cared for by a gastroenterologist, their outcomes tend to be better. However, as elderly persons with IBD continue to age, they may not have access to the same care as younger people with IBD due to deficiencies in their ability to use or access technology.

Abstract
Abstract
Background
Endoscopic retrograde cholangiopancreatography (ERCP) is a valuable diagnostic and therapeutic tool in primary sclerosing cholangitis (PSC). Although the complications of ERCP are well known in the general population, there is conflicting data regarding complications in patients with PSC. Factors that predict ERCP-related adverse events in PSC are also unclear.
Aims
To conduct a systematic review and meta-analyses to 1. compare ERCP-related adverse events in patients with and without PSC and 2. determine risk factors associated with ERCP-related adverse events in PSC.
Methods
A systematic search was conducted in Embase, PubMed and CENTRAL for studies published from January 1, 2000 to May 12, 2021. Eligible studies included adults with PSC undergoing ERCP and reported at least one ERCP-related adverse event (bleeding, perforation, pancreatitis, cholangitis) or risk factor associated with complications. Raw event rates for adverse events and risk factors were used to calculate odds ratios (ORs) which were then pooled using random-effects models.
Results
Four studies contributed to the first meta-analysis. There was a significant three-fold increase in the 30-day odds of cholangitis in PSC compared to those without PSC (4.3% vs. 2.0%; OR 3.26, 95% CI 1.08–9.90; p=0.037; I2=73.0%) (Figure 1). However, there were no significant differences in 30-day pancreatitis (4.2% vs. 3.4%; OR 0.89, 95% CI 0.26–3.07; p=0.851; I2=87.9%), bleeding (0.3% vs. 1.1%; OR 0.36, 95% CI 0.06–2.21; p=0.272; I2=50.3%), or perforation (0.7% vs. 0.5%; OR 1.19, 95% CI 0.40–3.51; p=0.752; I2=28.5%).
In a second meta-analysis, risk factors contributing to post-ERCP pancreatitis (PEP) in PSC were pooled from five studies. While female sex was not associated with PEP, accidental passage of wire into the pancreatic duct (OR 7.44, 95% CI 3.33–16.65; p<0.001; I2=65.0%) and biliary sphincterotomy (OR 4.80, 95% CI 1.92–12.03; p=0.001; I2=73.1%) were associated with higher PEP odds.
Conclusions
In the context of limited comparative data and study heterogeneity, PSC patients have higher odds of post-ERCP cholangitis despite the majority receiving antibiotics. Odds of bleeding, pancreatitis, and perforation were similar between groups. Accidental wire passage and biliary sphincterotomy increased odds of PEP, which helps identify higher-risk groups. Future studies should elucidate ERCP-related risks in PSC and guide preventive strategies.

Abstract
BACKGROUND There is increasing interest in direct oral anticoagulants (DOACs), given their safety and convenience in atrial fibrillation, compared with vitamin K antagonists (VKAs). However, the use of DOACs in left ventricular (LV) thrombi is considered off-label, with current guidelines recommending VKAs. The aim of this meta-analysis was to compare the safety and efficacy of DOACs to VKAs in the management of LV thrombi. METHODS A systematic search was conducted for studies published between January 1, 2009 and January 31, 2021 in PubMed, Embase, and CENTRAL. Included studies compared DOACs to VKAs for the treatment of LV thrombi and reported on relevant outcomes. Odds ratios (ORs) were pooled with a random-effects model. RESULTS Sixteen cohort studies and 2 randomized controlled trials were identified, which included 2666 patients (DOAC = 674; VKA = 1992). Compared with VKAs, DOACs were associated with a statistically significant reduction in stroke (OR 0.63, 95% confidence interval [CI] 0.42-0.96; P = 0.03; I 2 = 0%). There were no significant differences in bleeding (OR 0.72, 95% CI 0.50-1.02; P = 0.07; I2 = 0%), systemic embolism (OR 0.77, 95% CI 0.41-1.44; P = 0.41; I2 = 0%), stroke or systemic embolism (OR 0.83, 95% CI 0.53-1.33; P = 0.45; I2 = 33%), mortality (OR 1.01, 95% CI 0.64-1.57; P = 0.98; I2 = 0%) or LV thrombus resolution (OR 1.29, 95% CI 0.83-1.99; P = 0.26; I2 = 56%). CONCLUSIONS Within the context of low-quality evidence, there was a statistically significant reduction in stroke among those treated with DOACs, without an increase in bleeding. There were no significant differences in systemic embolism, stroke or systemic embolism, mortality, or LV thrombus resolution, suggesting that DOACs may be a reasonable option for treatment of LV thrombi.

Abstract
OBJECTIVES To collect, appraise, select, and report the best available national estimates of cigarette consumption since 1970. DESIGN Systematic collection of comparable data. SETTING AND POPULATION 71 of 214 countries for which searches for national cigarette consumption data were conducted, representing over 95% of global cigarette consumption and 85% of the world's population. MAIN OUTCOME MEASURES Validated cigarette consumption data covering 1970-2015 were identified for 71 countries. Data quality appraisal was conducted by two research team members in duplicate, with greatest weight given to official government sources. All data were standardised into units of cigarettes consumed per year in each country, a detailed accounting of data quality and sourcing was prepared, and all collected data and metadata were made freely available in an open access dataset. RESULTS Cigarette consumption fell in most countries over the past three decades but trends in country specific consumption were highly variable. For example, China consumed 2.5 million metric tonnes (MMT) of cigarettes in 2013, more than Russia (0.36 MMT), the United States (0.28 MMT), Indonesia (0.28 MMT), Japan (0.20 MMT), and the next 35 highest consuming countries combined. The US and Japan achieved reductions of more than 0.1 MMT from a decade earlier, whereas Russian consumption plateaued, and Chinese and Indonesian consumption increased by 0.75 MMT and 0.1 MMT, respectively. These data generally concord with modelled country level data from the Institute for Health Metrics and Evaluation and have the additional advantage of not smoothing year-over-year discontinuities that are necessary for robust quasi-experimental impact evaluations. CONCLUSIONS Before this study, publicly available data on cigarette consumption have been limited; they have been inappropriate for quasi-experimental impact evaluations (modelled data), held privately by companies (proprietary data), or widely dispersed across many national statistical agencies and research organisations (disaggregated data). This new dataset confirms that cigarette consumption has decreased in most countries over the past three decades, but that secular country specific consumption trends are highly variable. The findings underscore the need for more robust processes in data reporting, ideally built into international legal instruments or other mandated processes. To monitor the impact of the WHO Framework Convention on Tobacco Control and other tobacco control interventions, data on national tobacco production, trade, and sales should be routinely collected and openly reported.

Abstract
Only 30% of Ontarians are registered organ donors in spite of the vast unmet need for organ donations in Ontario, Canada. The purpose of this quality improvement (QI) initiative was to increase the number of registered organ donors in a primary care practice by providing an educational fact sheet and registration form to patients in the clinic's waiting room. Three Plan-Do-Study-Act (PDSA) cycles were conducted. In the first PDSA cycle, we created an information sheet to explain the need for organ donors and the registration process. Nine patients were surveyed regarding the clarity of the information sheet, which resulted in subsequent modification of the information sheet prior to the second PDSA cycle. For the second cycle, the revised information sheet was attached to a donor registration form and distributed to 30 patients in the primary care practice over a two-week period. 23 forms were returned, in which 4 patients were already registered organ donors and 5 patients completed registration forms. In the third PDSA cycle, a more compelling graphic was used on the pamphlet. Similarly, 30 forms were distributed; 23 forms were returned, with 6 newly completed registration forms. Overall, the project increased the donor registration rate from 10.0% to 28.3%. The process allowed patients to become more knowledgeable about organ donation need and aware of the Trillium Gift of Life website. We believe that providing patients with an information pamphlet and registration form in the clinic waiting room enhanced their awareness of organ donation and facilitated registration without delay. This QI initiative represents an effective and practical study to increase donor knowledge and provide opportunities for interested individuals to become registered organ donors.

Abstract
BACKGROUND Celebrities are highly influential people whose actions and decisions are watched and often emulated by wide audiences. Many celebrities have used their prominent social standing to offer medical advice or endorse health products, a trend that is expected to increase. However, the extent of the impact that celebrities have in shaping the public's health-related knowledge, attitudes, behaviors, and status is unclear. This systematic review seeks to answer the following questions: (1) Which health-related outcomes are influenced by celebrities? (2) How large of an impact do celebrities actually have on these health-related outcomes? (3) Under what circumstances do celebrities produce either beneficial or harmful impacts? METHODS Ten databases were searched, including MEDLINE, EMBASE, PsycINFO, PubMed, CINAHL, Communication Complete, Sociological Abstracts, Social Sciences Citation Index, Journals @ Scholars Portal, and ProQuest Dissertations & Theses A&I. Two reviewers conducted title and abstract screening and full-text screening to identify primary studies that employed empirical methods (either quantitative or qualitative) to examine celebrities' impact on health-related knowledge, attitudes, behaviors, or status outcomes. DISCUSSION The results of this review will contribute to our understanding of celebrity influences and how to design positive evidence-based celebrity health promotion activities. In addition, these findings can help inform the development of media reporting guidelines pertaining to celebrity health news and provide guidance to public health authorities on whether and how to respond to or work with celebrities.

Abstract
Incidentally discovered pituitary lesions are commonly encountered in the current era of ever-increasing imaging. Individualizing a particular approach implies a thorough analysis of existing evidence and balancing it against different patient expectations. We will illustrate the application of principles of Evidence-Based Medicine to a case of a pituitary incidentaloma by formulating questions that are important to patient care and finding related evidence. Our objective is to reflect the opportunities and the challenges that an evidence-based clinical approach offers to clinicians and patients.

Abstract
Abstract
Background
The authors have reported a newly recognized hypoglyacemic disorder, non-insulinoma pancreatogenous hypoglycaemia syndrome (NIPHS), which is characterized by postprandial hyperinsulinaemic hypoglycaemia, negative 72-h fast, negative transabdominal and intraoperative ultrasonography, spiral computed tomography and coeliac axis angiography, positive selective arterial calcium stimulation test (SACST), absence of insulinoma but presence of islet hypertrophy and nesidioblastosis, and relief of symptoms from gradient-guided partial pancreatectomy. Experience with the next five patients with this disorder (6–10; 1998–1999) compared with the original five (1–5; 1996–1998) is reported.
Results
Wide age range, male predominance, postprandial occurrence of symptoms, negative radiological localization, nesidioblastosis/islet hypertrophy, but no insulinoma characterized all ten cases. Response to SACST indicated widespread islet hyperfunction in patients 1 and 5; limitation to distribution of the SPA and GDA in patients 3, 4, 6 and 8, to distribution of the SPA in patients 2, 7 and 9, and to distribution of the SMA in patient 10. Except for patient 5, pancreatic resection to the left of the SMV was performed when only the SPA was positive on the SACST. Patients 5 and 8 have had recurrence of symptoms; they resolved within 3 months for patient 5.
Conclusion
NIPHS can usually be treated successfully with gradient-guided partial pancreatectomy.

Abstract
BACKGROUND Neuroglycopenia from endogenous hyperinsulinism usually is caused by insulinomas in adults. We recently reported a novel hypoglycemic disorder in 5 patients (patients 1 to 5) with postprandial neuroglycopenia, negative 72-hour fasts, negative perioperative imaging studies, but positive calcium stimulation tests and islet hypertrophy and nesidioblastosis in the gradient-guided resected pancreata. METHODS In this report we compare our experience with 5 additional patients (patients 6 to 10) with this syndrome to that in the original report. RESULTS The clinical features of patients 6 to 10 were similar to those of patients 1 to 5. Each had positive calcium stimulation testing that guided the extent of the distal pancreatectomy and histologic evidence of islet cell hypertrophy or nesidioblastosis. All 10 patients are alive from 9 to 50 months after operation, 1 of whom had no amelioration of neuroglycopenia. Minor perioperative complications occurred in 3 patients. One patient has experienced repeated bouts of acute pancreatitis, pseudocyst formation, and exocrine insufficiency. CONCLUSIONS We have identified adult patients with severe, postprandial hyperinsulinemic hypoglycemia from diffuse islet cell disease, 80% of whom have been well palliated with surgery. The results in 7 men have been better than those in the 3 women for reasons that are not obvious.

Abstract
In adults, endogenous hyperinsulinemic hypoglycemia is almost invariably due to insulinoma. In these patients with insulinoma, neuroglycopenic episodes exclusively after meal ingestion and negative 72-h fasts are extraordinarily rare. We describe five adults with neuroglycopenic episodes from hyperinsulinemic hypoglycemia within 4 h of meal ingestion and negative 72-h fasts. Each had negative transabdominal ultrasonography, spiral computed tomographic scanning, and celiac axis angiography of the pancreas. However, all showed positive selective arterial calcium stimulation tests indicative of pancreatic beta-cell hyperfunction. At pancreatic exploration, no insulinoma was detected by intraoperative ultrasonography and complete mobilization and palpation of the pancreas. Moreover, the resected pancreata showed islet hypertrophy and nesidioblastosis, but no insulinoma. No definite disease-causing mutation was detected in Kir6.2 and SUR1 genes, which encode the subunits of the pancreatic ATP-sensitive potassium channel responsible for glucose-induced insulin secretion. Four patients who underwent gradient-guided partial pancreatectomy have been free of hypoglycemic symptoms for up to 3 yr follow-up; the other, who underwent a limited distal pancreatectomy, has had brief recurrence of symptoms. The unique clinical features and responses to dynamic testing in these adults with hyperinsulinemic hypoglycemia in the absence of insulinoma may constitute a new syndrome of postprandial hypoglycemia from diffuse beta-cell hyperfunction.

Abstract
Infiltration of the retroocular space by inflammatory cells and the accumulation of glycosaminoglycans are histological characteristics of Graves' ophthalmopathy. Various cytokines, released by infiltrating immunocompetent cells and resident connective tissue cells, play a pivotal role in the evolution of this disease. The predominant cytokines secreted by orbital T cells during the course of the disease may govern the activity and stage of the local autoimmune process. Cytokine effects of potential relevance to the pathogenesis of Graves' ophthalmopathy include their ability to stimulate orbital fibroblasts to proliferate and secrete excess quantities of glycosaminoglycans. The edema associated with these hydrophilic macromolecules is directly responsible for many of the characteristic clinical features of the disease. In addition, certain cytokines induce or enhance the expression on orbital fibroblasts of immunomodulatory proteins. We review current evidence supporting the notion that cytokines are central to the development and evolution of Graves' ophthalmopathy.

Abstract
It is acknowledged that the TSH receptor (TSHr) on thyroid follicular cells is the autoantigen involved in the hyperthyroidism of Graves' disease. However, whether this receptor is expressed in extrathyroidal tissues, and whether it participates directly in the pathogenesis of Graves' ophthalmopathy (GO) are unclear. We sought to detect the expression of TSHr messenger ribonucleic acid (mRNA) and protein in orbital adipose/connective tissue specimens and in human orbital preadipocyte fibroblast cultures using liquid hybridization analysis and immunohistochemical methods. We demonstrated intact and variant TSHr mRNA transcripts and TSHr-like immunoreactivity in orbital adipose/connective tissue specimens from patients with GO. In addition, TSHr-like immunoreactivity was detected in early passage GO preadipocyte fibroblast cultures that were shown to include some adipose cells. In contrast, neither TSHr mRNA nor protein was detected in normal orbital adipose/connective tissue specimens or in late passage GO orbital fibroblast cultures containing no lipid-laden adipose cells. In conclusion, we showed that TSHr is expressed in the adipose/connective tissue of the diseased orbit in GO. In addition, TSHr is demonstrable in early passage GO preadipocyte orbital fibroblast cultures that contain a subpopulation of adipocytes. Subsequent passaging of these cells results in the loss of both TSHr expression and adipocyte-specific staining. These results suggest that both the expression of this receptor and the accumulation of adipose tissue in the orbit in GO may be induced in vivo by a humoral factor(s) not present in the cell culture environment.

Abstract
The association of invasive fibrous thyroiditis (IFT) with foci of extracervical fibrosclerosis is well recognized. Affected sites include the retroperitoneum, the mediastinum, the biliary tract, and the orbit. The development of subcutaneous fibrosclerosis, however, is extremely rare. We report a patient with known invasive fibrous thyroiditis and hypoparathyroidism who presented with localized subcutaneous fibrosclerosis of the anterior chest wall resulting in compression of his ventriculoperitoneal shunt. The aetiology of IFT has remained unclear. Several histological and serological features, including the presence of mononuclear cells within the fibrosclerotic process, the occurrence of microscopic vasculitis, and the detection of autoantibodies directed against thyroid-specific antigens in a large proportion of patients with IFT, currently support the notion of autoimmune mechanisms playing a role in the pathogenesis of this rare disease.

Abstract
OBJECTIVE To determine the efficacy of the ovine corticotropin-releasing hormone (oCRH) stimulation test in distinguishing between adrenocorticotropic hormone (ACTH)-dependent types of Cushing's syndrome. METHODS The cortisol and ACTH responses to intravenously administered oCRH were determined in 64 patients with pituitary-dependent Cushing's syndrome and 13 patients with ectopic ACTH production. RESULTS Of the 64 patients with pituitary-dependent Cushing's syndrome, 57 (89%) had a positive ACTH response to administration of oCRH (an increase of 50% or more above baseline), and 56 (88%) had a positive cortisol response (an increase of 20% or more above baseline). One patient with an ectopic ACTH-secreting tumor had a false-positive cortisol response to administration of oCRH. Two patients with ectopic ACTH-secreting tumors had false-positive responses to both ACTH and cortisol after oCRH was administered. Because both these patients did not have hypercortisolemia at the time of testing, they were excluded from the statistical analysis. When analyzed on the basis of ACTH response alone, oCRH testing yielded a diagnostic sensitivity and specificity for the diagnosis of pituitary-dependent hypercortisolism of 89% and 100%, respectively. The positive predictive value was 100%, and the negative predictive value was 61%. CONCLUSION oCRH testing distinguished between the ectopic ACTH syndrome and pituitary-dependent hyper-cortisolism in most cases. Therefore, this test is a useful procedure in the diagnostic evaluation of ACTH-dependent forms of Cushing's syndrome.
