Objective: To investigate an association of vaginal bleeding-affected deliveries with the long-term risk of cancer as compared with vaginal bleeding-unaffected deliveries and pregnancies ending in a termination or miscarriage. Design: Registry-based cohort study in Denmark, 1995-2017. Setting: Danish health and administrative registries. Participants: Deliveries (N=37,085) affected by vaginal bleeding (VB) within 20 gestational weeks among 35,517 women, VB-unaffected deliveries (N=1,362,760) among 783,020 women, pregnancies ending in a termination (N=324,395) among 239,729 women or miscarriage (N=137,040) among 121,303 women. Main outcome measures: Incidence rates (IR) per 10,000 person-years and cumulative incidence of cancer at the end of up to 24 years of follow-up, hazard ratios (HR) with 95% confidence intervals (CIs) adjusted for age, calendar year, reproductive history, history of chronic conditions, medication use, and socioeconomic factors using Cox proportional hazards regression. Results: We observed 1,725 cancer events (IR=32.1, 95% CI: 30.6-33.6) following VB-affected deliveries, 52,620 events (IR=31.5, 95% CI: 31.2-31.7) following VB-unaffected deliveries, 12,925 events (IR=30.1, 95% CI: 29.6-30.6) following a termination and 6,080 events (IR=34.3, 95% CI: 33.4-35.1) following a miscarriage. We found no association between VB and any cancer in comparison with VB-unaffected deliveries (HR=0.98, 95% CI: 0.93-1.03), terminations (HR=1.00, 95% CI: 0.94-1.06) and miscarriages (HR=1.04, 95% CI: 0.94-1.14). Specifically, there was no increase in relative risk of breast (HR=0.94, 95% CI: 0.86-1.03), cervical (0.94, 0.77-1.14), ovarian and fallopian tube (1.16, 0.81-1.66), uterine cancer (0.78, 0.46-1.33) and other site-specific cancers across all comparisons and in sensitivity analyses. Conclusions: Having a VB-affected pregnancy ending in a delivery was not associated with an increased risk of cancer in women in comparison with having a VB-unaffected pregnancy ending in a delivery, termination or miscarriage.

Appendicitis is a common surgical condition for children. However, environmental effects, such as piped water supply, on pediatric appendicitis risk remain unclear. This longitudinal, nationwide, cohort study aimed to compare the risk of appendicitis among children with different levels of piped water supply. Using data from Taiwan Water Resource Agency and National Health Insurance Research Database, we identified 119,128 children born in 1996–2010 from areas of the lowest piped water supply (prevalence 51.21% to 63.06%) as the study cohort; additional 119,128 children of the same period in areas of the highest piped water supply (prevalence 98.97% to 99.63%) were selected as the controls. Both cohorts were propensity-score matched by baseline variables. We calculated the hazard ratios (HRs) and 95% confidence intervals (CIs) of appendicitis in the study cohort compared to the controls by Cox proportional hazards regression. The study cohort had a raised overall incidence rates of appendicitis compared to the control cohort (12.8 vs. 8.7 per 10,000 person-years). After covariate adjustment, the risk of appendicitis was significantly increased in the study cohort (adjusted HR = 1.46, 95% CI: 1.35, 1.58, p < 0.001). Subgroup and sensitivity analyses showed consistent results that children with low piped water supply had a higher risk of appendicitis than those with high piped water supply. This study demonstrated that children with low piped water supply were at an increased risk of appendicitis. Enhancement of piped water availability in areas lacking adequate, secure, and sanitized water supply may protect children against appendicitis.

ObjectiveTo investigate whether fungus-derived statins are associated with a lower risk of incident Alzheimer disease (AD) compared with synthetic statins using real-world clinical practice data.MethodsWe identified a population-based retrospective cohort of patients aged ≥60 years newly prescribed a statin between January 1, 1994, and December 31, 2012, and followed until March 31, 2015, using the UK Clinical Practice Research Datalink. Statins were consecutively classified according to their type, lipophilicity, and potency. For each group, we calculated the crude AD incidence rates per 1,000 person-years. Time-dependent Cox proportional hazards models adjusted for propensity score deciles were used to estimate hazard ratios (HRs) with 95% confidence interval (CIs) of incident AD associated with different statin categories.ResultsOver the 18-year study period, we identified 465,085 statin users, including 7,669 patients who developed AD during 2,891,268 person-years of follow-up (incidence rate 2.65 [95% CI 2.59–2.71] per 1,000 person-years). Compared to synthetic, fungus-derived statins were associated with an increased risk of AD (HR 1.09, 95% CI 1.03–1.15). Lipophilic statins also were associated with higher AD risk (HR 1.18, 95% CI 1.09–1.27) compared to hydrophilic statins, while statin potency did not modify the risk of AD (adjusted HR 1.03, 95% CI 0.98–1.08). The risk was further reduced in sensitivity analyses.ConclusionFungus-derived and lipophilic statins were not associated with decreased incidence of AD compared to synthetic and hydrophilic statins. The modest variations in the risk of incident AD observed between statin characteristics needs to be evaluated in future studies on their possible heterogeneous neuroprotective effect.

Objectives The objectives of this article are to evaluate the association between migraine and trigeminal neuralgia and to investigate the effects of age, sex, migraine subtype, and comorbid risk factors on trigeminal neuralgia development. Methods This population-based cohort study was conducted using data from Taiwan’s National Health Insurance Research Database. Individuals aged ≥ 20 years with neurologist-diagnosed migraine between 2005 and 2009 were included. A non-headache age-, sex-, and propensity score-matched control cohort was selected for comparison. All participants were followed until the end of 2010, death, or the occurrence of trigeminal neuralgia. Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for comparison of the risk of trigeminal neuralgia between groups. Results Both cohorts ( n = 137,529 each) were followed for a mean of 3.1 years. During the follow-up period, 575 patients (421,581 person-years) in the migraine cohort and 88 matched controls (438,712 person-years) were newly diagnosed with trigeminal neuralgia (incidence rates, 136.39 and 20.06/100,000 person-years, respectively). The HR for trigeminal neuralgia was 6.72 (95% CI, 5.37–8.41; p < 0.001). The association between migraine and trigeminal neuralgia remained significant in sensitivity analyses. Among migraine subtypes, patients with migraine with aura were at greater risk of trigeminal neuralgia development. No other significant interaction was identified in subgroup analyses. Conclusions Migraine is a previously unidentified risk factor for trigeminal neuralgia. The association between these conditions suggests a linked underlying mechanism, which is worthy of further exploration.

The potential association between appendectomy and non-typhoidal Salmonella (NTS) infection has not been elucidated. We hypothesized that appendectomy may be associated with gut vulnerability to NTS. The data were retrospectively collected from the Taiwan National Health Insurance Research Database to describe the incidence rates of NTS infection requiring hospital admission among patients with and without an appendectomy. A total of 208,585 individuals aged ≥18 years with an appendectomy were enrolled from January 2000 to December 2012, and compared with a control group of 208,585 individuals who had never received an appendectomy matched by propensity score (1:1) by index year, age, sex, occupation, and comorbidities. An appendectomy was defined by the International Classification of Diseases, Ninth Revision, Clinical Modification Procedure Codes. The main outcome was patients who were hospitalized for NTS. Cox proportional hazards models were applied to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). Two sensitivity analyses were conducted for cross-validation. Of the 417,170 participants (215,221 (51.6%) male), 208,585 individuals (50.0%) had an appendectomy, and 112 individuals developed NTS infection requiring hospitalization. In the fully adjusted multivariable Cox proportional hazards regression model, the appendectomy group had an increased risk of NTS infection (adjusted HR (aHR), 1.61; 95% CI, 1.20–2.17). Females and individuals aged 18 to 30 years with a history of appendectomy had a statistically higher risk of NTS than the control group (aHR, 1.92; 95% CI, 1.26–2.93 and aHR, 2.67; 95% CI, 1.41–5.07). In this study, appendectomy was positively associated with subsequent hospitalization for NTS. The mechanism behind this association remains uncertain and needs further studies to clarify the interactions between appendectomy and NTS.

<b><i>Background:</i></b> The relationship between long-term body mass index (BMI) variability, weight change slope, and risk of cardiovascular outcomes in Chinese hypertensive patients has not been fully elucidated. <b><i>Methods:</i></b> A total of 20,737 patients with hypertension and three BMI measurements between 2006 and 2011 were included. Average real variability (ARV) was used to evaluate variability, and the subjects were divided into three groups: tertile 1 with BMI_ARV ≤0.86; tertile 2 with 0.86 &#x3c; BMI_ARV ≤ 1.60; and tertile 3 with BMI_ARV &#x3e;1.60. Cox proportional-hazards models were used to analyze the risk of cardiovascular and cerebrovascular diseases (CVD) in each group. <b><i>Results:</i></b> There were 1,352 cases of CVD during an average follow-up of 6.62 years. The 7-year cumulative incidence rates of CVD, stroke, and myocardial infarction (MI) in tertile 3 were 7.53, 6.13, and 1.56%, respectively. After adjustment for average BMI, weight change slope, and other traditional risk factors, the hazard ratio (HR) values for CVD, stroke, and MI in the highest tertile were 1.21 (95% CI 1.05–1.39), 1.21 (95% CI 1.04–1.38), and 1.20 (95% CI 0.88–1.62), respectively. Subgroup analysis showed that the HR values for CVD in tertile 3 were 1.71 (95% CI 1.06–2.75) and 0.98 (95% CI 0.61–1.58) in the positive and the negative weight change subjects, respectively. <b><i>Conclusions:</i></b> Higher BMI variability was associated with increased risk of CVD in hypertensive subjects with weight gain but not in those with weight loss, independent of traditional cardiovascular risk factors.

Introduction Evidence suggests that current levels of tritium emissions from CANDU reactors in Canada are not related to adverse health effects. However, these studies lack tritium-specific dose data and have small numbers of cases. The purpose of our study was to determine whether tritium emitted from a nuclear-generating station during routine operation is associated with risk of cancer in Pickering, Ontario. Methods A retrospective cohort was formed through linkage of Pickering and north Oshawa residents (1985) to incident cancer cases (1985–2005). We examined all sites combined, leukemia, lung, thyroid and childhood cancers (6–19 years) for males and females as well as female breast cancer. Tritium estimates were based on an atmospheric dispersion model, incorporating characteristics of annual tritium emissions and meteorology. Tritium concentration estimates were assigned to each cohort member based on exact location of residence. Person-years analysis was used to determine whether observed cancer cases were higher than expected. Cox proportional hazards regression was used to determine whether tritium was associated with radiation-sensitive cancers in Pickering. Results Person-years analysis showed female childhood cancer cases to be significantly higher than expected (standardized incidence ratio [SIR] = 1.99, 95% confidence interval [CI]: 1.08–3.38). The issue of multiple comparisons is the most likely explanation for this finding. Cox models revealed that female lung cancer was significantly higher in Pickering versus north Oshawa (HR = 2.34, 95% CI: 1.23–4.46) and that tritium was not associated with increased risk. The improved methodology used in this study adds to our understanding of cancer risks associated with low-dose tritium exposure. Conclusion Tritium estimates were not associated with increased risk of radiation-sensitive cancers in Pickering.

Background: High levels of C-reactive protein (CRP) are associated with cardiovascular disease, diabetes and mortality. It is unclear whether changes in CRP or persistently high CRP are associated with these outcomes beyond the baseline measure. Methods: We conducted a prospective cohort analysis of 10,229 participants from the ARIC Study with two measurements of CRP six years apart (at visits 2 and 4, 1990-92 and 1996-98, respectively). CRP was categorized into two groups using a standard cut-point for defining high levels (≥3 vs. <3 mg/L). Six-year change in CRP was categorized as: persistently not high (<3 mg/L), decreasing (≥3 to <3 mg/L), increasing (<3 to ≥3 mg/L), and persistently high (≥3 mg/L). Cox proportional hazards models were used to assess the association between visit 2 CRP, visit 4 CRP and six-year change in CRP and each of the following outcomes from visit 4 through 2010: diabetes, coronary heart disease, ischemic stroke, heart failure and all-cause mortality. Models were adjusted for traditional risk factors at visit 2. Sensitivity analyses additionally adjusted for visit 4 covariates. Results: Persons with CRP ≥3 mg/L at visit 2 or 4 had higher risk of each outcome compared to those with CRP <3 mg/L ( Table ). We observed higher risk of all outcomes in persons with persistently high CRP, and of all outcomes except stroke in persons with increasing CRP, compared to those with CRP <3 mg/L at both visits ( Table ). Persons whose CRP decreased from high to <3 mg/L did not have significantly increased risk of cardiovascular outcomes or diabetes compared to those with CRP persistently <3 mg/L. Results were similar after adjusting for visit 4 covariates. Conclusions: Persons with sustained high levels of CRP or whose CRP increased to high levels had higher risk of diabetes, cardiovascular disease, and death, while those whose levels decreased from high to moderate or low were at lower risk. Multiple measures of CRP may better characterize inflammatory status and provide more comprehensive information regarding long-term risk.

Background: Little is known about the association between coronary artery disease (CAD) and the risk of heart failure (HF) after myocardial infarction (MI), and whether it differs by reduced (HFrEF) or preserved (HFpEF) ejection fraction (EF) has yet to be determined. Subjects and Methods: Olmsted County, Minnesota residents (n=1,924; mean age, 64 years; 66% male) with first MI diagnosed in 1990-2010 and no prior HF were followed through 2013. Framingham Heart Study criteria were used to define HF, which was further classified according to EF (applying a 50% cutoff). The extent of angiographic CAD was defined at index MI according to the number of major epicardial coronary arteries with ≥50% lumen diameter obstruction. Fine & Gray and Cox proportional hazards regression models were used to assess the association of CAD categories with incidence of HF, and multiple imputation methodology was applied to account for the 19% with missing EF data. Results: During a mean (SD) follow-up of 6.7 (5.9) years, 594 patients developed HF. Adjusted for age and sex, with death considered a competing risk, the cumulative incidence rates of HF among patients with 1- (n=581), 2- (n=622), and 3-vessel disease (n=721) were 11.2%, 14.6% and 20.5% at 30 days; and 18.1%, 22.3% and 29.4% at 5 years after MI, respectively. The increased risk of HF with greater number of occluded vessels was only modestly attenuated after further adjustment for patient and MI characteristics, and did not differ materially by EF (Table). Conclusions: The extent of angiographic CAD expressed by the number of diseased vessels is independently associated with HF incidence after MI. The association is evident promptly after MI and applies to both HFrEF and HFpEF.

Introduction: Limited data exist on the electrophysiologic outcomes of patients undergoing anatomic repair (AR) for congenitally corrected transposition of the great arteries (ccTGA). AR was defined as an atrial switch procedure plus either arterial switch (ASO) or Rastelli operation. Aims: To report mid and late electrophysiologic outcomes after AR and identify risk factors for those outcomes. Methods: Single center retrospective cohort study of patients undergoing AR between 1993-2017. Data were collected from available records. Transplant-free survival to 1 year post repair was required for inclusion. Standard descriptive statistical analysis and Cox proportional hazards were used. Results: Of 85 patients included, 95% had lesions in addition to ccTGA: most commonly VSD (84%) and pulmonary stenosis or atresia (58%). Median age at AR was 1.5y (IQR 0.9-2.8) with Senning/ASO in 56%, Senning/Rastelli in 38%, and hemi-Senning/Glenn/Rastelli in 6%. During a median follow-up of 10.6y, 45 (53%) patients developed an arrhythmia requiring intervention. Atrial tachycardia (AT) in 27 (32%) or ventricular tachycardia (VT) in 11 (13%) patients required intervention at a median of 7.4y (IQR 1.6-15.3y) and 15.9y (IQR 4.5-17.9) post-AR, respectively. Treatments included chronic medications in 29 (64%), cardioversion in 15 (33%) and catheter ablation in 10 (22%). Median freedom from AT and VT was 17.3y and 25y post-AR, respectively. D-looped ventricles (p=0.03) and multiple operations prior to AR (p=0.02) were associated with increased AT risk; and native pulmonary stenosis with increased VT risk (p=0.01). Those needing heart failure/transplant referral had increased risk of both AT and VT (both p=0.04). Pacemaker was implanted for heart block and/or SND prior to or during AR in 14 (16%), immediately post-op in 9 (11%), and late (median 6y post-AR) in 24 (28%). ICDs were implanted in 5 (6% of cohort), 4 for primary prevention. No patient had an appropriate shock. Conclusions: Anatomic ccTGA repair is associated with significant electrophysiologic morbidity. AT, VT, and SND develop at a similar incidence to that reported for d-TGA patients after atrial switch. The incidence of AV block follows a similar trajectory to that of physiologically palliated ccTGA.

Abstract Background Osteoarthritis (OA) is the most common joint disease, but its association with mortality is unclear. Methods We analysed data on adult participants in the 1988–94 and 1999–2010 National Health and Nutrition Examination Surveys, followed for mortality through 2011. OA was defined by self-report, and in a subset of participants 60 years or older with knee X-rays, radiographic knee OA (RKOA) was defined as Kellgren–Lawrence score ≥2. Cox proportional hazards were used to determine the mortality hazard ratio (HR) associated with self-reported OA and RKOA, adjusting for covariates. Results The sample included 51 938 participants followed for a median 8.9 years; 2589 of them had knee X-rays and were followed for a median of 13.6 years. Self-reported OA and RKOA prevalences were 6.6% and 40.6%, respectively. Self-reported OA was not associated with mortality. RKOA was associated with an increased risk of mortality from cardiovascular diseases (CVD) {HR 1.43 [95% confidence interval (CI): 1.32, 1.64]}, diabetes [HR 2.04 (1.87, 2.23)] and renal diseases [HR 1.14 (1.04, 1.25)], but with a reduced risk of cancer mortality [HR 0.88 (0.80, 0.96)]. Participants with early RKOA onset (diagnosed before age 40) had a higher risk of mortality from all causes [HR 1.53 (1.43, 1.65)] and from diabetes [HR 7.18 (5.45, 9.45)]. Obese participants with RKOA were at increased risk of mortality from CVD [HR 1.89 (1.56, 2.29)] and from diabetes [HR: 3.42 (3.01, 3.88)]. Conclusions Self-reported OA was not associated with mortality. RKOA was associated with higher CVD, diabetes and renal mortality, especially in people with early onset of the disease or with obesity.
