- BACKGROUND: To evaluate the association of acne in late adolescence with the risk for subsequent malignant melanoma (MM) in men.METHODS: Swedish register-based cohort study of 242,096 males born between 1952 and 1956, who took part in compulsory assessments for Swedish military conscription in late adolescence between 1969 and 1975, with subsequent diagnoses of MM (n=1,058) up to December 31, 2009. Covariates included measures of childhood circumstances and information from adolescence on presence of acne, physical fitness, cognitive function, body mass index (BMI), and a summary of diagnoses. Cox regression was used for the analysis.RESULTS: In total 1,058 men were diagnosed with MM. Acne was not associated with subsequent MM, with an adjusted hazard ratio (and 95% confidence interval) of 0.95 (0.61 to 1.49). Men with parents who were agricultural workers, and men who lived in northern Sweden, had lower physical fitness, or lower cognitive function had a lower risk of MM. Overweight and obesity was associated with a raised risk, with an adjusted hazard ratio of 1.39 (1.14, 1.71).CONCLUSIONS: Acne in late adolescence is unlikely to represent a raised risk for subsequent MM in men. Overweight or obesity was identified as a raised risk for MM, possibly due to the associated increased skin surface area.

- Background & Aims: Studies on pregnancy characteristics and mode of delivery and risk of later celiac disease in offspring are inconsistent. In recent decades rates of cesarean delivery and preterm birth survival have increased while at the same time the prevalence of celiac disease has doubled.Methods: In this population-based case-control study we examined the risk of celiac disease in individuals exposed to cesarean delivery and adverse fetal events (ie, low Apgar score, small for gestational age, low birth weight, preterm birth, and neonatal infections). Prospectively recorded pregnancy data were obtained from the Swedish Medical Birth Register between 1973 and 2008. Study participants consisted of 11,749 offspring with biopsy-verified celiac disease identified through histopathology reports from Sweden's 28 pathology departments, and 53,887 age- and sex-matched controls from the general population.Results: We found a positive association between elective cesarean delivery and later celiac disease (adjusted odds ratio [OR], 1.15; 95% confidence interval [CI], 1.04-1.26), but no increased risk of celiac disease after emergency (adjusted OR, 1.02; 95% CI, 0.92-1.13) or any cesarean delivery (adjusted OR, 1.06; 95% CI, 0.99-1.13). Infants born small for gestational age were at a 21% increased risk of celiac disease (95% CI, 1.09-1.35), whereas other pregnancy exposures did not increase the risk of future celiac disease.Conclusions: The positive association with elective, but not emergency, cesarean delivery is consistent with the hypothesis that the bacterial flora of the newborn plays a role in the development of celiac disease.

- Objective: Exposure to elemental mercury vapor can impair neurological function as it is neurotoxic in doses higher than usually found in dentistry. Little is known about the potential effects of fetal exposure to elemental mercury among offspring of female dental workers. We investigated cognitive function among offspring of women working in dentistry at the time of their pregnancy.Methods: We compared results for cognitive function examinations taken by the majority of young men in Sweden at the time of compulsory military enlistment (age 17-18 years). Sons of female dentists (N=365) and dental nurses (N=3181) born during the 1960-1970s were compared with sons of female physicians (N=378) and assistant nurses (N=12 667).Results: Analysis by linear regression showed that sons of dental workers had similar or higher cognitive function test results compared to their matched cohorts.Conclusion: We found no evidence of poorer cognitive function among male offspring of female dentists or dental nurses.

- Aims: Dental personnel are exposed to mercury when using dental amalgam. This exposure constitutes a potential hazard to offspring of women working in dentistry. The present study examined increased mortality risk in offspring of mothers working in dentistry.Methods: Mortality was compared between sons of dental personnel and sons of nondental health-care personnel. Hazard ratios were calculated for three decades (1960s-1980s), when the magnitude of mercury exposure in dentistry was likely to have varied.Results: During the 1960s, there was a statistically significant increase in the risk of neonatal mortality for sons of dental nurses when compared with sons of assistant nurses: hazard ratio (HR) 1.82 (95% confidence interval, CI: 1.04-3.22). There was no increased risk in the subsequent decades, but a trend test demonstrated a consistent decrease in the risk over the three decades: HR for trend 0.63 (95% CI: 0.44-0.90). The raised mortality risk was limited to neonatal mortality. The comparison between dentists and physicians had insufficient statistical power.Conclusions: There is no increased mortality risk among sons of female dentists after the 1960s. Although the results should be interpreted with caution, they suggest a modestly raised risk of neonatal mortality, during the 1960s, when exposure to mercury was thought to be highest.

- Background: Microscopic colitis, comprising collagenous colitis (CC) and lymphocytic colitis (LC), is a common cause of chronic diarrhoea. The long-term prognosis is not well described.Aim: To study outcome of symptoms and health-related quality of life (HRQoL).Methods: A case-control study using a postal questionnaire with three population-based controls per patient matched for age, sex and municipality. HRQoL was assessed by the Short Health Scale (SHS). Patients in clinical remission, defined as a mean of <3 stools/day, were evaluated separately (CC; n=72, LC; n=60).Results: The study included 212 patients and 627 matched controls. Median disease duration was 5.9 (range 0.5-27) years and 6.4 (0.3-14.8) years for CC and LC respectively. Abdominal pain, fatigue, arthralgia, myalgia, faecal incontinence and nocturnal defecation were significantly more prevalent in CC patients compared with controls. These differences persisted in CC patients in clinical remission with respect to abdominal pain (36% vs. 21%), fatigue (54% vs. 34%), arthralgia (61% vs. 41%) and myalgia (53% vs. 37%). In LC patients, abdominal pain, fatigue, faecal incontinence and nocturnal defecation were more prevalent compared with controls. In LC patients in clinical remission, fatigue was more prevalent compared with controls (54% vs. 37%). These differences were statistically significant (P<0.05). All four HRQoL dimensions (symptom burden, social function, disease-related worry, general well-being) were impaired in patients with active CC and LC.Conclusions: Although considered to be in clinical remission, patients with microscopic colitis suffer from persisting symptoms such as abdominal pain, fatigue, arthralgia or myalgia several years after diagnosis.

- Background/Objectives: Children and adolescents undergoing treatment for cancer are exposed to multiple factors that impact the development of peak bone mass and bone quality. The aims of this study were to examine the risks and cumulative incidence of osteoporotic fractures in childhood cancer survivors and identify subgroups at higher risk.Design/Methods: In the national cancer registries of Denmark, Finland, Iceland and Sweden we identified patients diagnosed with cancer before 20 years of age from the start of registration in the 1940s and 1950s through 2008. We compared 26.334 one‐year survivors with a cohort of 162.372 age‐ and sex‐matched population comparison subjects selected from the national population registries. With data derived from national hospital registries we estimated the standardized hospitalization rate ratios (SHRR) and the mean cumulative count (MCC) of hospital admissions for osteoporotic fractures. To identify subgroups at risk we used Cox regression models to generate hazard ratios (HR) for osteoporotic fractures. Death and new cancer were treated as competing risks.Results: The estimated SHRR for the first osteoporotic fracture was 1.41 (95% CI; 1.27‐1.58) but the MCC for recurrent osteoporotic fractures did not differ between the survivors and the comparison group. The SHRR for isolated hip fractures was 2.90 (2.32‐3.63). The adjusted HR for osteoporotic fracture as the first event was 1.53 (1.09‐2.16) if cancer was diagnosed 15‐19 years and 2.10 (1.48‐2.98) for long‐term survivors of CNS tumors. Survivors 15‐19 years at cancer diagnosis and long‐term survivors of CNS tumors were also at higher risk of experiencing a second fracture, HR 3.29 (1.65‐6.55) and HR 2.71 (1.45‐5.05), respectively.Conclusions: Childhood cancer survivors are at higher risk of being hospitalized for osteoporotic fractures but the burden of recurrent fractures is not higher. For subgroups at risk, surveillance of bone health and measures to increase bone strength and prevent fractures should be encouraged.

- Relapse is the main reason for treatment failure in childhood acute lymphoblastic leukemia. Despite improvements in the up-front therapy, survival after relapse is still relatively poor, especially for high-risk relapses. The aims of this study were to assess outcomes following acute lymphoblastic leukemia relapse after common initial Nordic Society of Paediatric Haematology and Oncology protocol treatment; to validate currently used risk stratifications, and identify additional prognostic factors for overall survival. Altogether, 516 of 2735 patients (18.9%) relapsed between 1992 and 2011 and were included in the study. There were no statistically significant differences in outcome between the up-front protocols or between the relapse protocols used, but an improvement over time was observed. The 5-year overall survival for patients relapsing in the period 2002-2011 was 57.5 +/- 3.4%, but 44.7 +/- 3.2% (P<0.001) if relapse occurred in the period 1992-2001. Factors independently predicting mortality after relapse included short duration of first remission, bone marrow involvement, age ten years or over, unfavorable cytogenetics, and Down syndrome. T-cell immunophenotype was not an independent prognostic factor unless in combination with hyperleukocytosis at diagnosis. The outcome for early combined pre-B relapses was unexpectedly poor (5-year overall survival 38.0 +/- 10.6%), which supports the notion that these patients need further risk adjustment. Although survival outcomes have improved over time, the development of novel approaches is urgently needed to increase survival in relapsed childhood acute lymphoblastic leukemia.

- The dynamic growth of the skeleton during childhood and adolescence renders it vulnerable to adverse effects of cancer treatment. The lifetime risk and patterns of skeletal morbidity have not been described in a population-based cohort of childhood cancer survivors. A cohort of 26 334 1-year cancer survivors diagnosed before 20 years of age was identified from the national cancer registries of Denmark, Finland, Iceland and Sweden as well as a cohort of 127 531 age- and sex-matched comparison subjects randomly selected from the national population registries in each country. The two cohorts were linked with data from the national hospital registries and the observed numbers of first-time hospital admissions for adverse skeletal outcomes among childhood cancer survivors were compared to the expected numbers derived from the comparison cohort. In total, 1987 childhood cancer survivors had at least one hospital admission with a skeletal adverse event as discharge diagnosis, yielding a rate ratio (RR) of 1.35 (95% confidence interval, 1.29-1.42). Among the survivors, we observed an increased risk for osteonecrosis with a RR of 25.9 (15.0-44.5), osteoporosis, RR 4.53 (3.28-6.27), fractures, RR 1.27 (1.20-1.34), osteochondropathies, RR 1.57 (1.28-1.92) and osteoarthrosis, RR 1.48 (1.28-1.72). The hospitalization risk for any skeletal adverse event was higher among survivors up to the age of 60 years, but the lifetime pattern was different for each type of skeletal adverse event. Understanding the different lifetime patterns and identification of high-risk groups is crucial for developing strategies to optimize skeletal health in childhood cancer survivors.

- Reduced glomerular filtration rate defines chronic kidney disease and is associated with cardiovascular and all-cause mortality. We conducted a meta-analysis of genome-wide association studies for estimated glomerular filtration rate (eGFR), combining data across 133,413 individuals with replication in up to 42,166 individuals. We identify 24 new and confirm 29 previously identified loci. Of these 53 loci, 19 associate with eGFR among individuals with diabetes. Using bioinformatics, we show that identified genes at eGFR loci are enriched for expression in kidney tissues and in pathways relevant for kidney development and transmembrane transporter activity, kidney structure, and regulation of glucose metabolism. Chromatin state mapping and DNase I hypersensitivity analyses across adult tissues demonstrate preferential mapping of associated variants to regulatory regions in kidney but not extra-renal tissues. These findings suggest that genetic determinants of eGFR are mediated largely through direct effects within the kidney and highlight important cell types and biological pathways.
