RESUMEN

BACKGROUND: Crohn's disease (CD) is a chronic autoimmune disease in which inflammation can progress to complications of stricturing and/or penetrating disease. Real-world data on burden of complicated CD phenotypes are limited. METHODS: We analyzed cross-sectional data from the SPARC IBD (Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease) registry from 2016 to 2020. Four mutually exclusive phenotype cohorts were created: inflammatory CD (CD-I), complicated CD (stricturing CD, penetrating CD, and stricturing and penetrating CD [CD-SP]). Statistical analyses were performed using CD-I as the reference. RESULTS: A total of 1557 patients were identified: CD-I (n = 674, 43.3%), stricturing CD (n = 457, 29.4%), penetrating CD (n = 166, 10.7%), and CD-SP (n = 260, 16.7%). Patients with complicated phenotypes reported significantly greater use of tumor necrosis factor inhibitors (84.2%-86.7% vs 66.0%; P < .001) and corticosteroids (75.3%-82.7% vs 68.0%; P < .001). Patients with CD-SP reported significantly more aphthous ulcer (15.4% vs 10.5%; P < .05), erythema nodosum (6.5% vs 3.6%; P < .05), inflammatory bowel disease-related arthropathy (25.8% vs 17.2%; P < .01), liquid stools (24.2% vs 9.3%; P < .001), nocturnal fecal incontinence (10.8% vs 2.5%; P < .001), and CD-related surgery (77.7% vs 12.2%; P < .001). CONCLUSIONS: Patients with complicated CD phenotypes reported higher rates of active CD-related luminal and extraintestinal manifestations, and underwent more surgeries, despite being more likely to have received biologics than those with CD-I. The potential for early recognition and management of CD-I to prevent progression to complicated phenotypes should be explored in longitudinal studies.


Patients with complicated (stricturing and/or penetrating) Crohn's disease (CD) phenotypes have a higher disease burden, despite greater use of biologics, than patients with inflammatory CD. Early recognition and optimized management of CD may prevent progression to complicated phenotypes.

RESUMEN

OBJECTIVE: To examine environmental factors that influence risk of thyroid cancer. METHODS: We performed a case-control study utilizing thyroid cancer cases from the California Cancer Registry (1999-2012) and controls sampled in a population-based manner. Study participants were included if they were diagnosed with thyroid cancer, lived in the study area at their time of diagnosis, and were ≥35 years of age. Controls were recruited from the same area and eligible to participate if they were ≥35 years of age and had been living in California for at least 5 years prior to the interview. We examined residential exposure to 29 agricultural use pesticides, known to cause DNA damage in vitro or are known endocrine disruptors. We employed a validated geographic information system-based system to generate exposure estimates for each participant. RESULTS: Our sample included 2067 cases and 1003 controls. In single pollutant models and within a 20-year exposure period, 10 out of 29 selected pesticides were associated with thyroid cancer, including several of the most applied pesticides in the United States such as paraquat dichloride [odds ratio (OR): 1.46 (95% CI: 1.23, 1.73)], glyphosate [OR: 1.33 (95% CI: 1.12, 1.58)], and oxyfluorfen [OR: 1.21 (95% CI: 1.02, 1.43)]. Risk of thyroid cancer increased proportionately to the total number of pesticides subjects were exposed to 20 years before diagnosis or interview. In all models, paraquat dichloride was associated with thyroid cancer. CONCLUSIONS: Our study provides first evidence in support of the hypothesis that residential pesticide exposure from agricultural applications is associated with an increased risk of thyroid cancer.

RESUMEN

The COVID-19 pandemic has precipitated broad and extensive changes in the way people live and work. While the general subject of working from home has recently drawn increased attention, few studies have assessed gender differences in vulnerability to the potential mental health effects of working from home. Using data from 1,585 workers who participated in the Health, Ethnicity, and Pandemic (HEAP) study, a national survey conducted in the U.S. during the COVID-19 pandemic in October 2020, associations of working from home with psychological distress were examined with weighted logistic regression among 1,585 workers and stratified by gender. It was found that workers who worked from home had higher odds of psychological distress (aOR and 95% CI = 2.62 [1.46, 4.70]) compared to workers who did not work from home, adjusting for demographic factors, socioeconomic status, and health behaviors. In gender-stratified analyses, this positive association between working from home and psychological distress was significant in women (aOR and 95% CI = 3.68 [1.68, 8.09]) but not in men. These results have implications for female workers' mental health in the transition towards working from home in the COVID-19 pandemic era.

RESUMEN

The COVID-19 pandemic continues to exert immense societal impacts, with recent data showing inequitable distribution of consequences among racial and ethnic groups. The objective of this study was to assess associations between COVID-related work stressors and psychological distress, with special emphasis on differences by race and ethnicity. Data were from the population-based California Health Interview Survey (CHIS) 2020. Associations of individual and cumulative work stressors, including job loss, reduced work hours, and working from home, with psychological distress in 12,113 workers were examined via multivariable linear regression, and stratified analyses were conducted for racial and ethnic subgroups. After adjustment for covariates, compared to workers with no work stressors, those who experienced either one or two/more work stressors had higher psychological distress (ßs and 95% CIs were 0.80 [0.51, 1.09] and 1.98 [1.41, 2.56], respectively). Notably, experiencing cumulative (two/more) work stressors had much stronger effects on psychological distress among participants who were Black (ß and 95% CI were 3.51 [1.09, 5.93]) or racial minorities (ß and 95% CI were 3.57 [1.10, 6.05]). Occupational consequences of the COVID-19 pandemic were associated with increased psychological distress in Californian workers and inequitably distributed, with racial and ethnic minorities suffering the greatest burden.

RESUMEN

Background: Cardiovascular disease is becoming increasingly prevalent in low and middle-income countries (LMIC), and high blood pressure (BP) is one of the main risk factors. The efficacy and sustainability of worksite health promotion (WHP) programs for BP reduction in LMIC have yet to be determined. Methods: This non-randomized company-based trial evaluated 6- and 12-months effects of a WHP intervention on BP among 2,002 participating workers from seven Mexican companies. Intervention and control groups were assigned at the company level. The intervention included nutrition counseling, physical exercise, and stress management components. Mixed models assessed differences in BP change between intervention and control companies in intent-to-treat (ITT), per-protocol (PerP), and as-treated (AsTr) analyses, and also within-group changes stratified by company, intervention component, and baseline cardiovascular risk factor levels. All analyses were adjusted for potential confounders. We accounted for missing data and loss to follow-up using inverse probability of censoring weighting. Results: ITT analyses revealed mean BP change differences of -1.1 mmHg at 12 months (95% CI: -2.9; 0.6) in intervention companies relative to control companies. PerP and AsTr analyses confirmed this finding. Within-group analyses showed consistent BP reductions at both 6 and 12 months. Substantial differences in BP changes ranging from diastolic -6.1 mmHg, (95% CI: -11.2; -1.2) to systolic -13.0 mmHg (95% CI: -16.0; -10.1) were found among individuals with diabetes at baseline in intervention companies relative to control companies. Conclusion: After 1 year, WHP was associated with modest but uncertain BP reductions. Substantial reductions were mainly observed among diabetic workers.

RESUMEN

Globally, many millions of people still lack access to safe drinking water and sanitation facilities. Here, we examined associations between household availability of improved drinking water and sanitation, respectively, and use of maternal and child health (MCH) services in South Asian countries. Demographic and Health Survey population-based data from Bangladesh, Nepal, India, and Pakistan were used, restricted to women with a child aged 0-36 months (n = 145,262). Types of households' water source and sanitation facilities were categorized based on the World Health Organization and UNICEF's definitions of "improved" and "unimproved". We applied logistic regressions to estimate odds ratios (OR) and 95% confidence intervals (CI) for improved water and sanitation, respectively, and reported antenatal care visits, having a skilled attendant at birth, and infant vaccination coverage, stratified by maternal education. Among lower educated women, access to improved water source was associated with greater ORs for presence of a skilled attendant at delivery and their children having up-to-date immunizations (OR: 1.29; 95% CI: 1.17, 1.42). Among lower and higher educated women, improved sanitation (vs. unimproved) was associated with greater ORs for having had adequate antenatal care visits (OR: 1.74; 95% CI: 1.62, 1.88; OR: 1.71; 95% CI: 1.62, 1.80), and similarly for having had a skilled attendant at birth, and children with up-to-date immunizations. Approaches addressing water/sanitation and MCH services across sectors could be a suggested public health strategy.

RESUMEN

OBJECTIVE: Retinoblastoma is the most common primary intraocular tumor affecting children. We examine the role of parental occupational exposures and risk of retinoblastoma among offspring. METHODS: Our population-based case-control study linked data from four nationwide Danish registries and included all cases of retinoblastoma diagnosed in Danish children (<5 y, n = 144) between 1975 and 2014. We focused on two biologically relevant time periods: 90 days preconception to conception for fathers; conception to birth for mothers. Parents were grouped into major industry headings created from Danish industry codes. RESULTS: We observed increased risk of all retinoblastoma for children of fathers in the food and drink industry and iron and metal industry. Bilateral disease was associated with paternal work in manufacturing and land transportation. CONCLUSION: Our results suggest that some occupational exposures may increase the risk of childhood sporadic retinoblastoma.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) is a multi-national problem with many health consequences. Some research suggests that reducing rates of child marriage can improve gender norms and health outcomes related to IPV. Here, we examine whether changes in national child marriage laws can improve attitudes about domestic violence and reduce intimate partner violence at scale. METHODS: Data on attitudes towards violence and violence experienced were obtained from the Demographic and Health Surveys (DHS) and longitudinal data on child marriage policy from WORLD and MACHEquity databases (1995-2012). Treatment countries were included if they improved their national child marriage policies from harmful (under 18) to more protective and control countries were included if they had a constant child-marriage policy that allowed girls to marry under the age of 18. Our final data set included 5 treatment and 14 control countries for women's outcomes, 2 treatment and 9 control countries for men's outcomes and 2 treatment and 7 control countries for IPV outcomes (for which fewer countries collect data). We combined individual level responses to five questions on attitudes about domestic violence to create a scale from 0 (always unacceptable) to 5 (always acceptable). All analyses employed a difference-in-differences approach adjusting for individual and country level predictors. RESULTS: Data were available for 532 255 women, of which 96 414 also completed the domestic violence modules, and 104 704 men. National changes to a protective child marriage policy were associated with improved attitudes towards violence among women (-0.21 points, 95% confidence interval (CI) = -0.28, -0.14) and men (-0.98 points, 95% CI = -1.13, -0.83). Additionally, the risk of women experiencing physical and sexual abuse reduced by a greater proportion in treatment compared to control countries (odds ratio OR = 0.65, 95% CI = 0.50, 0.84; OR = 0.63, 95% CI = 0.45, 0.88, respectively). CONCLUSIONS: Our large multi-national study is the first of its kind to critically evaluate the role of national policy on attitudes towards and experiences of IPV among both men and women, and finds that these laws have protective outcomes. Our results are consistent with the hypothesis that gender egalitarian laws positively influence norms and health at the national level.

RESUMEN

BACKGROUND: The etiology of childhood cancer is largely unknown, though some research suggests an infectious origin of hematopoietic, central nervous system (CNS) and bone cancers. METHODS: We examined parental occupational social contact as a proxy for exposure to infectious agents and risk of childhood cancer. This population-based case-control study utilized a linkage of four Danish data-registries, and included 3581 cases (<17 years, diagnosed 1973-2012) and 358,100 age-matched controls. We examined the risks of leukemia, lymphoma, CNS and bone cancer related to high occupational social contact from (1) conception to birth and (2) birth to diagnosis. RESULTS: Acute lymphoblastic leukemia (ALL) and bone cancer were inversely associated with high maternal social contact from conception to birth (OR: 0.86, 95% CI: 0.67-1.10) and birth to diagnosis (OR: 0.54, 95% CI: 0.34-0.86). Children of fathers with high social contact from birth to diagnosis had an increased risk of bone cancers, particularly in rural areas (OR: 1.65, 95% CI: 1.03-2.63). Parental social contact was associated with increased risk of astrocytoma, with strongest associations found in first-born children (maternal: OR: 1.54, 95% CI: 1.02-2.32; paternal: OR: 1.82, 95% CI: 1.05-3.17). CONCLUSION: Our results support the notion of a role of infections for some cancer types.

RESUMEN

Evidence that gender inequalities and restrictive norms adversely affect health is extensive; however, far less research has focused on testing solutions. We first comprehensively reviewed the peer-reviewed and grey literature for rigorously evaluated programmes that aimed to reduce gender inequality and restrictive gender norms and improve health. We identified four mutually reinforcing factors underpinning change: (1) multisectoral action, (2) multilevel, multistakeholder involvement, (3) diversified programming, and (4) social participation and empowerment. Following this review, because little research has investigated the effects of national-level law and policy reforms, we conducted original quasi-experimental studies on laws and policies related to education, work, and income, all social determinants of health in which deep gender inequalities exist. We examined whether the laws and policies significantly affected health outcomes and gender norms, and whether law-induced and policy-induced changes in gender norms mediated the health effects, in areas for which longitudinal data existed. Laws and policies that made primary education tuition-free (13 intervention countries with the law and/or policy and ten control countries without) and that provided paid maternity and parental leave (seven intervention and 15 control countries) significantly improved women's and their children's health (odds ratios [OR] of 1·16-2·10, depending on health outcome) and gender equality in household decision making (OR 1·46 for tuition-free and 1·45 for paid maternity and parental leave) as a proxy indicator of gender norms. Increased equality partially mediated the positive effects on health outcomes. We conclude by discussing examples of how improved governance can support gender-equitable laws, policies, and programmes, immediate next steps, and future research needs.

RESUMEN

OBJECTIVES: We examined associations between parental occupational chemical exposures up to 10 years before conception and the risk of sporadic retinoblastoma among offspring. METHODS: In our multicentre study on non-familial retinoblastoma, parents of 187 unilateral and 95 bilateral cases and 155 friend controls were interviewed by telephone. Exposure information was collected retroactively through a detailed occupational questionnaire that asked fathers to report every job held in the 10 years before conception, and mothers 1 month before and during the index pregnancy. An industrial hygienist reviewed all occupational data and assigned an overall exposure score to each job indicating the presence of nine hazardous agents. RESULTS: We estimated elevated ORs for unilateral and bilateral retinoblastoma among offspring of fathers who were exposed to polycyclic aromatic hydrocarbons or paints in the 10 years before conception. However, only for exposure to paints did confidence limits exclude the null for bilateral disease (OR: 8.76, 95% CI: 1.32 to 58.09). Maternal prenatal exposure to at least one of the nine agents was related to increased risk of unilateral disease in their children (OR: 5.25, 95% CI: 1.14 to 24.16). Fathers exposed to at least one of the nine agents and who were ≥30 years of age were at increased risk of having a child diagnosed with bilateral retinoblastoma (OR: 6.59, 95% CI: 1.34 to 32.42). CONCLUSIONS: Our results suggest a role for several hazardous occupational exposures in the development of childhood retinoblastoma.

RESUMEN

PURPOSE: To examine whether parental pesticide exposure contributes to the development of sporadic retinoblastoma. DESIGN: Case-control study. METHODS: Data were collected by a large multicenter study of sporadic retinoblastoma in which parents of 99 unilateral and 56 bilateral age-matched case-control pairs were interviewed by telephone. Retrospective exposure information was collected on the type, location, timing, and frequency of residential pesticide use. We used conditional logistic regression analyses to estimate odds ratios for maternal pesticide exposure in the month before or during pregnancy and to assess whether the type of product, and the circumstances under which it was applied, were associated with risk of disease. RESULTS: Unilateral retinoblastoma was associated with parental insecticide use (odds ratio [OR], 2.8; confidence interval [CI], 1.1-6.7) and the use of professional lawn or landscape services (OR, 2.8; CI, 1.0-8.2). For bilateral disease we observed large point estimates for several exposures but the small number of cases rendered these results uninformative (ie, resulted in wide confidence intervals). Whether parents used the pesticide inside vs outside the home did not appear to modify risk estimates for unilateral retinoblastoma (OR, 2.5; CI, 0.9-7.0 vs OR, 2.5; CI, 1.0-6.5), nor did the type, frequency, timing related to pregnancy, or applicator of pesticide used influence estimates to an appreciable degree for disease. CONCLUSIONS: Our results suggest that parental pesticide exposure before or during pregnancy may play a role in the development of childhood retinoblastoma. Retrospectively collected exposure data introduces the possibility of recall bias; therefore, results should be interpreted cautiously until additional studies are conducted.

RESUMEN

BACKGROUND: The early age at retinoblastoma occurrence, the most common eye malignancy in childhood, suggests that perinatal factors may contribute to its etiology. METHODS: In a large multicenter study of non-familial retinoblastoma, we conducted structured interviews with the parents of 280 cases and 146 controls to elicit information on health during the perinatal period. We used unconditional logistic regression to assess associations between retinoblastoma and parental fertility treatment, birth control use in the year prior to pregnancy, maternal health conditions and the use of prescription medications during pregnancy, and whether mothers breastfed the index child. RESULTS: Bilateral retinoblastoma was related to maternal underweight (body mass index <18.5) prior to pregnancy [Odds Ratio (OR) = 4.5, 95 % confidence interval (CI) 1.0, 20]. With regards to unilateral retinoblastoma, we observed a negative association with the use of condoms in the year prior to pregnancy (OR = 0.4, CI 0.2, 0.9), and a trend towards a positive association with maternal diabetes (OR = 2.2, CI 0.8, 6.6). CONCLUSIONS: Results from our study suggest a role for several maternal health and reproductive factors. Given that there are few epidemiologic studies of retinoblastoma, our results require replication in studies which utilize medical record review.
