Most evidence for an association between excess body weight and cancer risk has been derived from studies of relatively short duration with little reference to the effect on tumor site. This study was designed to evaluate the association between categories of body mass index (BMI: <20, 20–25, 25–30, and >30 kg/m2) and the incidence of colon and lung cancer over 43 years of follow-up (1963–2006), in 10,043 men from the Israeli Ischemic Heart Disease (IIHD) prospective cohort (mean age at baseline 49.3 years, mean BMI 25.7 kg/m2). Data from the Israel National Cancer Registry was linked with the IIHD, and the Cox proportional hazards regression model was applied to analyze the relative risks for lung and colon cancer across BMI categories at baseline. Three hundred cases of lung cancer (2.9%) and 328 cases of colon cancer (3.3%) were diagnosed in the total population. Applying a multivariate model adjusted for age, smoking intensity, and total cholesterol, higher BMI category was associated with an increased risk of colon cancer [HR = 1.22 (95% CI 1.02–1.45)], and with a decreased risk for lung cancer [HR = 0.66 (95% CI 0.56–0.77)]. In this long-term follow-up study over four decades, we observed a consistent dose-response pattern between BMI and increased risk for colon cancer, but decreased risk for lung cancer. Specific associations between excess body weight and cancer risk may suggest different patterns of body fat and cancer incidence at a given site.

Long Term Follow Up

Purpose Hereditary retinoblastoma (Rb) survivors have increased risk of subsequent malignant neoplasms (SMNs). Previous studies reported elevated radiotherapy (RT) -related SMN risks, but less is known about chemotherapy-related risks. Patients and Methods In a long-term follow-up study of 906 5-year hereditary Rb survivors diagnosed from 1914 to 1996 and observed through 2009, treatment-related SMN risks were quantified using cumulative incidence analyses and multivariable Cox proportional hazards regression models with age as the underlying time scale. Results Nearly 90% of Rb survivors were treated with RT, and almost 40% received alkylating agent (AA) –containing chemotherapy (predominantly triethylenemelamine). Median follow-up time to first SMN diagnosis was 26.3 years. Overall SMN risk was not significantly elevated among survivors receiving AA plus RT versus RT without chemotherapy (hazard ratio [HR], 1.27; 95% CI, 0.99 to 1.63). AA-related risks were significantly increased for subsequent bone tumors (HR, 1.60; 95% CI, 1.03 to 2.49) and leiomyosarcoma (HR, 2.67; 95% CI, 1.22 to 5.85) but not for melanoma (HR, 0.74; 95% CI, 0.36 to 1.55) or epithelial tumors (HR, 0.89; 95% CI, 0.48 to 1.64). Leiomyosarcoma risk was significantly increased for survivors who received AAs at age < 1 (HR, 5.17; 95% CI, 1.76 to 15.17) but not for those receiving AAs at age ≥ 1 year (HR, 1.75; 95% CI, 0.68 to 4.51). Development of leiomyosarcoma was significantly more common after AA plus RT versus RT (5.8% v 1.6% at age 40 years; P = .01). Conclusion This comprehensive quantification of SMN risk after chemotherapy and RT among hereditary Rb survivors also demonstrates an AA-related contribution to risk. Although triethylenemelamine is no longer prescribed, our findings warrant further follow-up to investigate potential SMN risks associated with current chemotherapies used for Rb.

Self Harm

BackgroundRepetition of deliberate self-harm (DSH) is a risk factor for suicide. Little information is available on the risk for specific groups of people who deliberately harm themselves repeatedly.AimsTo investigate the long-term risk of suicide associated with repetition of DSH by gender, age and frequency of repetition.MethodA mortality follow-up study to the year 2000 was conducted on 11583 people who presented to the general hospital in Oxford between 1978 and 1997. Repetition of DSH was determined from reported episodes prior to the index episode and episodes presenting to the same hospital during the follow-up period. Deaths were identified through national registers.ResultsThirty-nine percent of patients repeated the DSH. They were at greater relative risk of suicide than the single-episode DSH group (2.24; 95% CI 1.77–2.84). The relative risk of suicide in the repeated DSH group compared with the single-episode DSH group was greater in females (3.5; 95% C11.3–2.4) than males (1.8; 95% C1 2.3–5.3) and was inversely related to age (up to 54 years). Suicide risk increased further with multiple repeat episodes of DSH in females.ConclusionsRepetition of DSH is associated with an increased risk of suicide in males and females. Repetition may be a better indicator of risk in females, especially young females.

Corrected Transposition

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.

Lipid Components

Background. Metabolic syndrome has been linked to an increased cancer risk, but the role of dyslipidaemia in gastrointestinal malignancies is unclear. We aimed to assess the risk of oesophageal, stomach, colon, and rectal cancers using serum levels of lipid components.Methods. From the Swedish Apolipoprotein Mortality Risk (AMORIS) study, we selected 540,309 participants (> 20 years old) with baseline measurements of total cholesterol (TC), triglycerides (TG), and glucose of whom 84,774 had baseline LDL cholesterol (LDL), HDL cholesterol (HDL), apolipoprotein B (apoB), and apolipoprotein A-I (apoA-I). Multivariate Cox proportional hazards regression was used to assess glucose and lipid components in relation to oesophageal, stomach, colon, and rectal cancer risk.Results. An increased risk of oesophageal cancer was observed in persons with high TG (e.g. HR: 2.29 (95% CI: 1.42–3.68) for the 4th quartile compared to the 1st) and low LDL, LDL/HDL ratio, TC/HDL ratio, log (TG/HDL), and apoB/apoA-I ratio. High glucose and TG were linked with an increased colon cancer risk, while high TC levels were associated with an increased rectal cancer risk.Conclusion. The persistent link between TC and rectal cancer risk as well as between TG and oesophageal and colon cancer risk in normoglycaemic individuals may imply their substantiality in gastrointestinal carcinogenesis.

Introduction: Low magnesium (Mg) intake and/or status has been associated with increased risk of chronic disease, including cardiovascular disease (CVD) and cancer. However, whether and to what extent low serum Mg levels are associated with all-cause or cause-specific mortality in the general population is uncertain. Hypothesis: We aimed to quantify the dose-response associations between low concentrations of serum Mg and mortality from all causes, cancer, CVD, and stroke in the general US population. Methods: We analyzed prospective data on 14,353 participants aged 25-74 years with baseline measures of serum Mg concentrations from the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study 1971-2006. We estimated the mortality hazard ratios (HRs) for participants within predefined and clinically meaningful categories of serum Mg levels, including <0.7, 0.7-0.74, 0.75-0.79, 0.8-0.9 (normal reference), 0.9-0.94, 0.95-0.99, and ≥1.0 mmol/L, using Cox proportional hazards models. Restricted cubic spline models were applied to examine potentially nonlinear relationships between serum Mg and mortality. Results: During a mean follow-up of 27.6 years, 7,072 deaths occurred, 3,310 (47%) CVD deaths, 1,533 (22%) cancer deaths, and 281 (4%) stroke deaths. Twenty-one percent of all participants had low levels of serum Mg (<0.8 mmol/L) and 1.5% had extremely low serum Mg (<0.7 mmol/L). Age-adjusted all-cause mortality rates were 3845, 3491, 3471, 3400 (normal reference), 3531, 3525, and 3836 per 100,000 person-years for increasing categories of serum Mg; the HRs and 95% confidence intervals for increasing serum Mg were 1.32 (1.02-1.72), 0.93 (0.74-1.16), and 1.06 (0.96-1.18), 1.07 (0.97-1.18), 0.94 (0.77-1.13), and 0.93 (0.72-1.21), compared to the reference group (0.8-0.9 mmol/L). An L-shaped association between serum Mg concentrations and all-cause mortality was observed after adjusting for potential confounders (Figure). No statistically significant associations were observed between serum Mg and cancer, CVD, or stroke mortality. Conclusions: Very low serum Mg levels were significantly associated with all-cause mortality in the general US population. Our findings support the hypothesis that Mg deficiency as defined by very low serum Mg may have an important influence on mortality.
