Abstract
BACKGROUND Evidence is low regarding the choice of calcineurin inhibitor for immunosuppression after lung transplantation. We aimed to compare the use of tacrolimus once per day with ciclosporin twice per day according to the current definition of chronic lung allograft dysfunction (CLAD) after lung transplantation. METHODS ScanCLAD is an investigator-initiated, open-label, multicentre, randomised, controlled trial in Scandinavia evaluating whether an immunosuppressive protocol based on anti-thymocyte globulin induction followed by tacrolimus (once per day), mycophenolate mofetil, and corticosteroids reduces the incidence of CLAD after de novo lung transplantation compared with a protocol using ciclosporin (twice per day), mycophenolate mofetil, and corticosteroids. Patients aged 18-70 years who were scheduled to undergo double lung transplantation were randomly allocated (1:1) to receive either oral ciclosporin (2-3 mg/kg before transplantation and 3 mg/kg [twice per day] from postoperative day 1) or oral tacrolimus (0·05-0·1 mg/kg before transplantation and 0·1-0·2 mg/kg from postoperative day 1). The primary endpoint was CLAD at 36 months post transplantation, determined by repeated lung function tests and adjudicated by an independent committee, and was assessed with a competing-risks analysis with death and re-transplantation as competing events. The primary outcome was assessed in the modified intention-to-treat (mITT) population, defined as those who underwent transplantation and received at least one dose of study drug. This study is registered at ClinicalTrials.gov (NCT02936505) and EudraCT (2015-004137-27). FINDINGS Between Oct 21, 2016, and July 10, 2019, 383 patients were screened for eligibility. 249 patients underwent double lung transplantation and received at least one dose of study drug, and were thus included in the mITT population: 125 (50%) in the ciclosporin group and 124 (50%) in the tacrolimus group. The mITT population consisted of 138 (55%) men and 111 (45%) women, with a mean age of 55·2 years (SD 10·2), and no patients were lost to follow-up. In the mITT population, CLAD occurred in 48 patients (cumulative incidence 39% [95% CI 31-48]) in the ciclosporin group and 16 patients (13% [8-21]) in the tacrolimus group at 36 months post transplantation (hazard ratio [HR] 0·28 [95% CI 0·15-0·52], log-rank p<0·0001). Overall survival did not differ between groups at 3 years in the mITT population (74% [65-81] for ciclosporin vs 79% [70-85] for tacrolimus; HR 0·72 [95% CI 0·41-1·27], log-rank p=0·25). However, in the per protocol CLAD population (those in the mITT population who also had at least one post-baseline lung function test allowing assessment of CLAD), allograft survival was significantly better in the tacrolimus group (HR 0·49 [95% CI 0·26-0·91], log-rank p=0·021). Adverse events totalled 1516 in the ciclosporin group and 1459 in the tacrolimus group. The most frequent adverse events were infection (453 events), acute rejection (165 events), and anaemia (129 events) in the ciclosporin group, and infection (568 events), anaemia (108 events), and acute rejection (98 events) in the tacrolimus group. 112 (90%) patients in the ciclosporin group and 108 (87%) in the tacrolimus group had at least one serious adverse event. INTERPRETATION Immunosuppression based on use of tacrolimus once per day significantly reduced the incidence of CLAD compared with use of ciclosporin twice per day. These findings support the use of tacrolimus as the first choice of calcineurin inhibitor after lung transplantation.

Abstract
Previous studies have shown a decreased risk of prostate cancer for childless men; however, the cause of the association remains to be elucidated. The aim of our study was to assess the risk of prostate cancer by fatherhood status, also considering potential confounding factors. In a case-control study in Prostate Cancer data Base Sweden 2.0, a nationwide, population-based cohort, data on number of children, marital status, education, comorbidity and tumor characteristics obtained through nationwide healthcare registers and demographic databases for 117,328 prostate cancer cases and 562,644 controls, matched on birth year and county of residence, were analyzed. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for prostate cancer overall and by risk category, adjusting for marital status and education. Childless men had a decreased risk of prostate cancer compared to fathers, OR = 0.83 (95% CI = 0.82-0.84), and risk was lower for low-risk prostate cancer, OR = 0.74 (95% CI = 0.72-0.77), than for metastatic prostate cancer, OR = 0.93 (95% CI = 0.90-0.97). Adjustment for marital status and education attenuated the association in the low-risk category, adjusted OR = 0.87 (95% CI = 0.84-0.91), whereas OR for metastatic cancer remained virtually unchanged, adjusted OR = 0.92 (95% CI = 0.88-0.96). Our data indicate that the association between fatherhood status and prostate cancer to a large part is due to socioeconomic factors influencing healthcare-seeking behavior including testing of prostate-specific antigen levels.

Abstract
UNLABELLED Our goals were to evaluate the effect of half-life determination and differences in the half-life of 131I between patients with Graves' disease and toxic nodular goiter, and the influence of antithyroid drugs on iodine uptake. METHODS We reviewed the records of 555 patients who had received radioiodine treatment for Graves' disease and toxic nodular goiter to analyze iodine uptake, half-life values and pretreatment with antithyroid drugs. Two different methods of dose calculation were compared: one using repeated uptake measurements at 24 and 48 hr and 4 or 6 days to define the effective half-life. The other method assumed a half-life of 5 days and uptake at 24 hr only. All patients were treated according to the first method. A follow-up questionnaire was sent to 327 patients (238 responders) to assess the treatment outcome. RESULTS After comparing the results of the two methods, we found that repeat uptake measurements and determination of effective half-life results in administered activities that differ considerably from those calculated when an assumed, fixed half-life and a single uptake measurement are used. The simpler method would lead to over- as well as undertreatment of the patient. There was a functional difference between patients with Graves' disease and toxic nodular goiter, as reflected by the shorter 131I half-life in Graves' disease (mean 5.0 days) than toxic nodular goiter (mean 6.0 days) and a skewed distribution in toxic nodular goiter. Patients pretreated with antithyroid drugs had shorter 131I half-lives in both categories. Ten percent of the patients required more than one treatment; 94% of the patients with Graves' disease and 45% with toxic nodular goiter had thyroxine substitution 1-5 yr after treatment. CONCLUSION A dose calculation method that uses three uptake measurements provides sufficient data about the effective half-life of 131I in the thyroid. There is considerable difference in the half-life based on the disease being treated (Graves' disease or toxic nodular goiter). The 131I half-life also is shorter after pretreatment with anti-thyroid drugs. Thus, the simpler method leads to significant uncertainty, leading to over- as well undertreatment of the patient.
