Abstract Objective To assess the risk of colorectal cancer (CRC) in first degree relatives (parents and full siblings) of patients with precursor lesions (polyps) for CRC. Design Case-control study. Setting Linkage to the multi-generation register and gastrointestinal ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) histopathology cohort in Sweden. Participants 68 060 patients with CRC and 333 753 matched controls. Main outcome measures Multivariable adjusted odds ratios of CRC according to the number of first degree relatives with a colorectal polyp and the histology of polyps and age at diagnosis in first degree relatives. Subgroup analysis was also performed according to age at CRC diagnosis and evaluated the joint association of family history of colorectal polyps and family history of CRC. Results After adjusting for family history of CRC and other covariates, having a first degree relative with a colorectal polyp (8.4% (5742/68 060) in cases and 5.7% (18 860/333 753) in controls) was associated with a higher risk of CRC (odds ratio 1.40, 95% confidence interval 1.35 to 1.45). The odds ratios ranged from 1.23 for those with hyperplastic polyps to 1.44 for those with tubulovillous adenomas. To better put this risk in perspective, the age specific absolute risk of colon and rectal cancers was estimated according to family history of polyps based on the 2018 national CRC incidence in Sweden. For example, the absolute risk of colon cancer in individuals aged 60-64 years with and without a family history of colorectal polyp was, respectively, 94.3 and 67.9 per 100 000 for men and 89.1 and 64.1 per 100 000 for women. The association between family history of polyps and CRC risk was strengthened by the increasing number of first degree relatives with polyps (≥2 first degree relatives: 1.70, 1.52 to 1.90, P<0.001 for trend) and decreasing age at polyp diagnosis (<50 years: 1.77, 1.57 to 1.99, P<0.001 for trend). A particularly strong association was found for early onset CRC diagnosed before age 50 years (≥2 first degree relatives: 3.34, 2.05 to 5.43, P=0.002 for heterogeneity by age of CRC diagnosis). In the joint analysis, the odds ratio of CRC for individuals with two or more first degree relatives with polyps but no CRC was 1.79 (1.52 to 2.10), with one first degree relative with CRC but no polyps was 1.70 (1.65 to 1.76), and with two or more first degree relatives with both polyps and CRC was 5.00 (3.77 to 6.63) (P<0.001 for interaction). Conclusions After adjusting for family history of CRC, the siblings and children of patients with colorectal polyps are still at higher risk of CRC, particularly early onset CRC. Early screening for CRC might be considered for first degree relatives of patients with polyps.

Abstract Background Previous studies have indicated inconsistent relationships of diabetes with thyroid cancer risk, yet little is known in China. In this study, we aimed to investigate the associations between diabetes, diabetes duration and the risk of thyroid cancer in Chinese population. Methods A 1:1 matched case-control study was performed between 2015 and 2017 in Zhejiang Province including 2,937 thyroid cancer cases and 2,937 healthy controls. Odds ratios (ORs) with 95 % confidence intervals (CIs) for thyroid cancer were estimated in logistic regression models. Specific effects stratified by age, as well as sex, body mass index (BMI) and family history of diabetes were also examined. Results Overall, neither diabetes (OR = 0.75, 95 % CI: 0.21–2.73) nor diabetes duration (OR = 0.14, 95 % CI: 0.02–1.22 for diabetes duration ≦ 5 years; OR = 2.10, 95 % CI: 0.32–13.94 for diabetes duration > 5 years) was significantly associated with thyroid cancer. In stratified analyses, significant lower risk of thyroid cancer was observed among subjects with diabetes and shorter diabetes duration ( ≦ 5 years), but limited to those who were aged more than 40 years, female, overweight/obese and had positive family history of diabetes. Conclusions Diabetes and shorter diabetes duration were significantly associated with decreased risk of thyroid cancer in individuals characterized by older age, female sex, higher BMI and positive family history of diabetes.

Background <br />Preeclampsia is one of the leading causes of maternal and fetal morbidity and mortalities worldwide. Despite extensive research, the underlying cause of preeclampsia remains poorly understood. This study aimed to offer compelling evidence on the important risk factors of preeclampsia in Amhara region, Ethiopia.<br /><br />Methods<br />A case control study was conducted in public health facilities of Bahir Dar city from September 2014 to January 2015. A total of 453 (151 cases and 302 controls) pregnant women were enrolled in this study. Hemoglobin level and urinary tract infection (UTI) status were collected from clinical notes. Oral examination was performed by a dentist for detection of periodontal diseases. Univariate and multiple logistic regression analysis was conducted to determine the relationship of all the independent variables with the outcome variable. A p-value &lt;0.05 was declared statistically significant.<br /><br />Result<br />Advanced maternal age (AOR=4.79;95% CI 1.031-22.18), family history of hypertension (AOR=11.16;95% CI 5.41-41.43), history of diabetes mellitus (AOR=6.17;95% CI 2.11-20.33), UTI in the current pregnancy (AOR=6.58;95% CI 2.93-14.73), failure to comply with iron and folic acid supplement during pregnancy (AOR=8.32;95% CI 3.35-20.62), lack of exercise (AOR=3.33;95% CI 1.35-8.17), multiple pregnancy (AOR=4.05;95% CI 1.57-12.27), anemia (AOR=4.19;95% CI 1.27-13.92), and periodontal disease or gingivitis (AOR =3.51;95% CI 1.14-10.83) were associated with preeclampsia.<br /><br />Conclusion <br />Family history of hypertension was the most dominant risk factor for preeclampsia in pregnant women. Encouraging pregnant women to have health seeking behavior during pregnancy would provide a chance to diagnose preeclampsia as early as possible.

Abstract Background The incidence of systemic hypertension (HTN) among perinatally-HIV-infected (PHIV) patients appears to increase as they enter adulthood. Among non-perinatally HIV-infected adults both traditional and HIV-associated risk factors have been found to contribute to HTN. Whether these same factors contribute to HTN in PHIV is unknown. The purpose of this study was to determine the socio-demographic, clinical, virologic, and immunologic factors associated with HTN among a cohort of PHIV adolescents and young adults, aged ≥18 years. Methods We conducted a case–control study among a population of 160 PHIV adults with and without HTN who were receiving care at the University of Maryland and aged 18–35 years as of December 31, 2017. Covariates assessed included traditional risk factors such as age, family history of HTN, and smoking, as well as HIV- and antiretroviral-associated covariates. Results We identified 49 HTN cases (30.6%) and 111 (69.4%) controls. There were no significant differences in the odds of most traditional (age, gender, race, family history of HTN, tobacco, alcohol, and/or other drug use) or HIV-associated (CD4 nadir <100 cells/mm3, individual ART exposure, ART interruption) risk factors among PHIV adults with HTN compared with those with no diagnosis of HTN. Cases had lower odds of a history of treatment with lopinavir/ritonavir (LPV/r). Cases had 3.7 (95% CI 1.11, 12.56) times the odds of a prior diagnosis of chronic kidney disease (CKD) compared with controls after controlling for CD4 nadir and ARV treatment history. Conclusion The results of this study suggest that most traditional and HIV-related risk factors do not appear to increase the odds of having HTN in this PHIV cohort. However, HTN among PHIV may be driven in part by CKD, and a focus on the prevention and early management of CKD in this group may be necessary to prevent the development of HTN. Additionally, there may be as yet unidentified risk factors for HTN among PHIV which require further exploration. Given the large and growing population of PHIV entering adulthood worldwide, it is imperative to explore risk factors for and effects of HTN in large, diverse PHIV populations.
