RESUMEN
BACKGROUND: Sudden cardiac death (SCD) is the leading medical cause of death in athletes. To prevent SCD, screening for high-risk cardiovascular conditions (HRCC) is recommended. Screening strategies are based on a limited number of studies and expert consensus. However, evidence and efficacy of athlete HRCC screening is unclear. OBJECTIVE: To determine methodological quality and quality of evidence of athlete screening, and screening efficacy to detect HRCC in a systematic review. METHODS: We performed a systematic search of Medline, Embase, Scopus and Cochrane Library up to June 2021. We included articles containing original data of athlete cardiovascular screening, providing details of screening strategies, test results and HRCC detection. We assessed methodological quality of the included articles by QUADAS-2, quality of evidence of athlete HRCC screening by GRADE, and athlete HRCC screening efficacy by SWiM. RESULTS: Of 2720 citations, we included 33 articles (1991-2018), comprising 82 417 athletes (26.7% elite, 73.4% competitive, 21.7% women, 75.2% aged ≤35). Methodological quality was 'very low' (33 articles), caused by absence of data blinding and inappropriate statistical analysis. Quality of evidence was 'very low' (33 articles), due to observational designs and population heterogeneity. Screening efficacy could not be reliably established. The prevalence of HRCC was 0.43% with false positive rate (FPR) 13.0%. CONCLUSIONS: Methodological quality and quality of evidence on athlete screening are suboptimal. Efficacy could not be reliably established. The prevalence of screen detected HRCC was very low and FPR high. Given the limitations of the evidence, individual recommendations need to be prudent.
RESUMEN
In Western populations, the incidence of oesophageal squamous cell carcinoma (OSCC) has been declining, whereas the incidence of oesophageal adenocarcinoma (OAC) has been increasing. Our study examines temporal trends in the incidence of oesophageal cancer in the Netherlands between 1989 and 2016, in addition to predicting future trends through 2041. Data from the Netherlands Cancer Registry and Statistics Netherlands were collected to obtain incidence trends of OSCC and OAC for the period 1989 to 2016. Age-period-cohort (APC) modelling was used to estimate the contribution of age, calendar period and birth cohort on the observed incidence trends. To predict the future numbers of new cases of both OSCC and OAC from 2017 to 2041, log-linear APC models were fitted to the trends of 1989 to 2016. The age-standardised incidence rates of OSCC have decreased slightly for men and increased slightly for women. In contrast, a marked increase in the incidence of OAC was observed, ranging from 2.8 per 100 000 persons in 1989 to 10.1 in 2016. This increase in OAC incidence was more prominent in men, and it will result in an increased risk of OAC for successive generations. Future projections indicate that the incidence of OAC will further increase to 13.1 per 100 000 persons in 2037 to 2041, meaning that there will be 13 259 cases of OAC in 2037 to 2041, as compared to 9386 diagnoses in 2017 to 2021. The changing epidemiologic trends in oesophageal cancer in the Netherlands should be reflected in the development of prevention, early detection and treatment strategies.

BACKGROUND: Falls in people 65 years and older evaluated in the emergency department are increasing. Of all unintentional injury-related deaths among older people, 55% are due to falls. The impact of falls, especially concerning Dutch older people with the highest proportion of living independently worldwide, is unclear. OBJECTIVE: To identify the influence of age, gender, health conditions, and type of fall on the severity of injury, hospital length of stay, mortality, and discharge destination. METHODS: A total number of 6,084 patients from a comprehensive regional trauma care system, 65 years and older and hospitalized after a fall, were included. Groups were compared for patient-related factors and multivariable logistic regression analysis to explore the consequences. RESULTS: Mean age was 82 years (SD = 8.3), and 70% were female. Most falls (66.4%) were due to "slipping and tripping" or "falls on the same level," 57.4% had Injury Severity Scores between 9 and 12, and 43.3% were discharged home. Higher age and type of fall increased the likelihood of severe injuries. Men experienced shorter hospital stays than women and were less frequently discharged home. Mortality was higher in males (10.8%) than in females (6.7%) and increased with the American Society of Anesthesiologists scores for preexisting health conditions. CONCLUSION: Advanced age, gender, type of fall, and prior health status play a significant role in the severity of injuries, length of hospital stay, 30-day mortality, and higher discharge destination to care homes in older people hospitalized after a fall.

BACKGROUND: Sedentary behavior (SB) is associated with increased risks of detrimental health outcomes. Few studies have explored correlates of SB in physically active individuals. Furthermore, SB correlates may depend on settings of SB, such as occupation, transportation and leisure time sitting. This study aims to identify subject-, lifestyle- and health-related correlates for total SB and different SB domains: transportation, occupation, and leisure time. METHODS: Dutch participants were recruited between June, 2015 and December, 2016. Participant characteristics (i.e. age, sex, weight, height, marital status, education level, employment), lifestyle (sleep, smoking, alcohol consumption, physical activity) and medical history were collected via an online questionnaire. SB was assessed using the Sedentary Behavior Questionnaire and estimated for 9 different activities during weekdays and weekend days. Logistic regression was used to calculate odds ratios and 95% confidence intervals for the association between correlates and SB. Total SB was dichotomized at > 8 h/day and > 10 h/day, and being sedentary during transportation, occupation and leisure time at the 75th percentile (60 min/day, 275 min/day and 410 min/day, respectively). RESULTS: In total, 8471 participants (median age 55, 55% men) were included of whom 86% met the physical activity guidelines. Median SB was 9.1 h/day (Q25 6.3-Q75 12.0) during weekdays and 7.4 h/day (Q25 5.5-Q75 9.5) during weekend days. SB was most prevalent during leisure time (5.3 h/day; Q25 3.9-Q75 6.8), followed by occupation (2 h/day; Q25 0.1-Q75 4.6) and transportation (0.5 h/day; Q25 0.2-Q75 1.0). Younger age, male sex, being unmarried, higher education, employment and higher BMI were significantly related to higher levels of total SB. Younger age, male sex, employment, and higher BMI increased the odds for high SB volumes during occupation and transportation. Higher education, being unmarried and smoking status were positively associated with high volumes of occupational SB only, whereas older age, being unmarried, unemployment, higher BMI and poor health were positively linked to leisure time SB. CONCLUSIONS: SB is highly prevalent in physically active individuals, with SB during leisure time as the most important contributor. Correlates for high volumes of SB vary substantially across SB domains, emphasizing the difficulty to target this unhealthy lifestyle.

BACKGROUND: Breast density is known to affect breast cancer risk and screening sensitivity, but it may also be associated with breast cancer survival. The interpretation of results from previous studies on breast density and survival is complicated by the association between detection mode and survival. Here, we studied the effect of breast density on breast cancer-specific survival for different detection modes (screen-detected, interval ≤ 24 or > 24 months, non-participant). METHODS: Data from the Nijmegen (Dutch) breast cancer screening programme were used. Women diagnosed with invasive breast cancer between 1975 and 2011 were included. Breast density was assessed visually, based on a dichotomized Wolfe scale: 'fatty breasts' (≤25%) and 'dense breasts' (> 25%). Cox proportional hazard regression was used to obtain hazard ratios (HR). RESULTS: We identified 2742 eligible women, with a breast pattern available for 2233 women. A diagnosis of interval cancer (HR 2.06, 95% CI 1.62-2.61) led to a significantly increased risk of breast cancer death compared with screen-detected cancer. No significant cause-specific survival difference between women with dense and fatty breasts was observed (HR 0.94, 95% CI 0.77-1.15). The hazard was only higher for women with dense breasts among interval cancers ≤24 m (HR 1.07, 95% CI 0.74-1.56). The hazard appeared to be lower for women with dense breasts than for women with fatty breasts among screen-detected (HR 0.77, 95% CI 0.53-1.11) and interval cancers > 24 m (HR 0.80, 95% CI 0.53-1.20). None of the effects were statistically significant. CONCLUSIONS: Detection mode is strongly associated with breast cancer death. No clear association is apparent between breast density and breast cancer death, regardless of detection mode.

BACKGROUND: Between 2003 and 2010 digital mammography (DM) gradually replaced screen-film mammography (SFM) in the Dutch breast cancer screening programme (BCSP). Previous studies showed increases in detection rate (DR) after the transition to DM. However, national interval cancer rates (ICR) have not yet been reported. METHODS: We assessed programme sensitivity and specificity during the transition period to DM, analysing nationwide data on screen-detected and interval cancers. Data of 7.3 million screens in women aged 49-74, between 2004 and 2011, were linked to the Netherlands Cancer Registry to obtain data on interval cancers. Age-adjusted DRs, ICRs and recall rates (RR) per 1000 screens and programme sensitivity and specificity were calculated by year, age and screening modality. RESULTS: 41,662 screen-detected and 16,160 interval cancers were analysed. The DR significantly increased from 5.13 (95% confidence interval (CI):5.00-5.30) in 2004 to 6.34 (95% CI:6.15-6.47) in 2011, for both in situ (2004:0.73;2011:1.24) and invasive cancers (2004:4.42;2011:5.07), whereas the ICR remained stable (2004: 2.16 (95% CI2.06-2.25);2011: 2.13 (95% CI:2.04-2.22)). The RR changed significantly from 14.0 to 21.4. Programme sensitivity significantly increased, mainly between ages 49-59, from 70.0% (95% CI:68.9-71.2) to 74.4% (95% CI:73.5-75.4) whereas specificity slightly declined (2004:99.1% (95% CI:99.09-99.13);2011:98.5% (95% CI:98.45-98.50)). The overall DR was significantly higher for DM than for SFM (6.24;5.36) as was programme sensitivity (73.6%;70.1%), the ICR was similar (2.19;2.20) and specificity was significantly lower for DM (98.5%;98.9%). CONCLUSIONS: During the transition from SFM to DM, there was a significant rise in DR and a stable ICR, leading to increased programme sensitivity. Although the recall rate increased, programme specificity remained high compared to other countries. These findings indicate that the performance of DM in a nationwide screening programme is not inferior to, and may be even better, than that of SFM.

PURPOSE: It is difficult for clinicians to inform patients about the success rate of a treatment as a cervical anterior discectomy procedure. Ideally, a proportion of good outcome as rated by patients is known. Patient-reported outcome measurements are helpful. The purpose is to relate the difference in Neck Disability Index (NDI) after a cervical anterior discectomy procedure for single level cervical degenerative disc disease with the patients' rating of their actual clinical situation after long-term follow-up to define the substantial clinical benefit (SCB). METHODS: After completion of the NDI, patients who were surgically treated for cervical single level degenerative disease were asked to complete a five-item Likert scale to rate their clinical situation. After dichotomisation of the outcome in good versus less than good, a cut-off value was defined by determining the value of the difference of NDI with the highest specificity and sensitivity. Funding was not obtained. RESULTS: SCB for NDI after surgery for cervical single level degenerative disease should be set at ten with area under the curve (AUC) of 0.71 for sensitivity as well specificity. CONCLUSIONS: The goal for each treatment is a good outcome. While comparing treatments for cervical degenerative disc disease only those with an SCB of ten will be relevant for the patient, as patients who achieved this difference in NDI rated their actual situation at long-term follow-up as good.

Breast cancer screening is known to reduce breast cancer mortality. A high breast density may affect this reduction. We assessed the effect of screening on breast cancer mortality in women with dense and fatty breasts separately. Analyses were performed within the Nijmegen (Dutch) screening programme (1975-2008), which invites women (aged 50-74 years) biennially. Performance measures were determined. Furthermore, a case-control study was performed for women having dense and women having fatty breasts. Breast density was assessed visually with a dichotomized Wolfe scale. Breast density data were available for cases. The prevalence of dense breasts among controls was estimated with age-specific rates from the general population. Sensitivity analyses were performed on these estimates. Screening performance was better in the fatty than in the dense group (sensitivity 75.7% vs 57.8%). The mortality reduction appeared to be smaller for women with dense breasts, with an odds ratio (OR) of 0.87 (95% CI 0.52-1.45) in the dense and 0.59 (95% CI 0.44-0.79) in the fatty group. We can conclude that high density results in lower screening performance and appears to be associated with a smaller mortality reduction. Breast density is thus a likely candidate for risk-stratified screening. More research is needed on the association between density and screening harms.

Several reviews have estimated the balance of benefits and harms of mammographic screening in the general population. The balance may, however, differ between individuals with and without family history. Therefore, our aim is to assess the cumulative risk of screening outcomes; screen-detected breast cancer, interval cancer, and false-positive results, in women screenees aged 50-75 and 40-75, with and without a first-degree relative with a history of breast cancer at the start of screening. Data on screening attendance, recall and breast cancer detection were collected for each woman living in Nijmegen (The Netherlands) since 1975. We used a discrete time survival model to calculate the cumulative probability of each major screening outcome over 19 screening rounds. Women with a family history of breast cancer had a higher risk of all screening outcomes. For women screened from age 50-75, the cumulative risk of screen-detected breast cancer, interval cancer and false-positive results were 9.0, 4.4 and 11.1% for women with a family history and 6.3, 2.7 and 7.3% for women without a family history, respectively. The results for women 40-75 followed the same pattern for women screened 50-75 for cancer outcomes, but were almost doubled for false-positive results. To conclude, women with a first-degree relative with a history of breast cancer are more likely to experience benefits and harms of screening than women without a family history. To complete the balance and provide risk-based screening recommendations, the breast cancer mortality reduction and overdiagnosis should be estimated for family history subgroups.

BACKGROUND & AIMS: More than 20% of patients with inflammatory bowel disease (IBD) discontinue thiopurine therapy because of severe adverse drug reactions (ADRs); leukopenia is one of the most serious ADRs. Variants in the gene encoding thiopurine S-methyltransferase (TPMT) alter its enzymatic activity, resulting in higher levels of thiopurine metabolites, which can cause leukopenia. We performed a prospective study to determine whether genotype analysis of TPMT before thiopurine treatment, and dose selection based on the results, affects the outcomes of patients with IBD. METHODS: In a study performed at 30 Dutch hospitals, patients were assigned randomly to groups that received standard treatment (control) or pretreatment screening (intervention) for 3 common variants of TPMT (TPMT*2, TPMT*3A, and TPMT*3C). Patients in the intervention group found to be heterozygous carriers of a variant received 50% of the standard dose of thiopurine (azathioprine or 6-mercaptopurine), and patients homozygous for a variant received 0%-10% of the standard dose. We compared, in an intention-to-treat analysis, outcomes of the intervention (n = 405) and control groups (n = 378) after 20 weeks of treatment. Primary outcomes were the occurrence of hematologic ADRs (leukocyte count < 3.0*10(9)/L or reduced platelet count < 100*10(9)/L) and disease activity (based on the Harvey-Bradshaw Index for Crohn's disease [n = 356] or the partial Mayo score for ulcerative colitis [n = 253]). RESULTS: Similar proportions of patients in the intervention and control groups developed a hematologic ADR (7.4% vs 7.9%; relative risk, 0.93; 95% confidence interval, 0.57-1.52) in the 20 weeks of follow-up evaluation; the groups also had similar mean levels of disease activity (P = .18 for Crohn's disease and P = .14 for ulcerative colitis). However, a significantly smaller proportion of carriers of the TPMT variants in the intervention group (2.6%) developed hematologic ADRs compared with patients in the control group (22.9%) (relative risk, 0.11; 95% confidence interval, 0.01-0.85). CONCLUSIONS: Screening for variants in TPMT did not reduce the proportions of patients with hematologic ADRs during thiopurine treatment for IBD. However, there was a 10-fold reduction in hematologic ADRs among variant carriers who were identified and received a dose reduction, compared with variant carriers who did not, without differences in treatment efficacy. ClinicalTrials.gov number: NCT00521950.

BACKGROUND: Ongoing breast cancer screening programs can only be evaluated using observational study designs. Most studies have observed a reduction in breast cancer mortality, but design differences appear to have resulted in different estimates. Direct comparison of case-control and trial analyses gives more insight into this variation. Here, we performed case-control analyses within the randomized UK Age Trial. METHODS: The Age Trial assessed the effect of screening on breast cancer mortality in women ages 40-49 years. In our approach, case subjects were defined as breast cancer deaths between trial entry (1991-1997) and 2004. Women were ages 39-41 years at entry. For every case subject, five control subjects were selected. All case subjects were included in analyses of screening invitation (356 case subjects, 1,780 controls), whereas analyses of attendance were restricted to women invited to screening (105 case subjects, 525 age-matched controls). Odds ratios (OR) were estimated with conditional logistic regression. We used and compared two methods to correct for self-selection bias. RESULTS: Screening invitation resulted in a breast cancer mortality reduction of 17% (95% confidence interval [CI]: -36%, +6%), similar to trial results. Different exposure definitions and self-selection adjustments influenced the observed breast cancer mortality reduction. Depending on the method, "ever screened" appeared to be associated with a small reduction (OR: 0.86, 95% CI: 0.40, 1.89) or no reduction (OR: 1.02, 95% CI: 0.48, 2.14) using the two methods of correction. Recent attendance resulted in an adjusted mortality reduction of 36% (95% CI: -69%, +31%) or 45% (95% CI: -71%, +5%). CONCLUSIONS: Observational studies, and particularly case-control studies, are an important monitoring tool for breast cancer screening programs. The focus should be on diminishing bias in observational studies and gaining a better understanding of the influence of study design on estimates of mortality reduction.

OBJECTIVES: Differences in breast density between populations may explain part of the variation in regional breast cancer screening performance. This study aimed to determine whether regional differences in breast density distribution are present in the Dutch screening population. METHODS: As part of the DENSE trial, mammographic density was measured using a fully-automated volumetric method. The regions in our study were based on the geographic coverage of 14 reading units representing a large part of the Netherlands. General linear models were used. RESULTS: Four hundred eighty-five thousand and twenty-one screening participants with a median age of 60 years were included (2013-2014). The proportion of women with heterogeneously or extremely dense breasts ranged from 32.5% to 45.7% between regions. Mean percent dense volume varied between 6.51% (95% confidence interval [CI]: 6.46-6.55) and 7.68% (95% CI: 7.66-7.71). Age differences could not explain the variation. Socio-economic status (SES) was positively associated with volumetric density in all analyses (low SES: 6.95% vs. high SES: 7.63%; p trend < 0.0001), whereas a potential association between urbanisation and breast density only became apparent after SES adjustment. CONCLUSION: There appears to be geographic variation in mammographic density in the Netherlands, emphasizing the importance of including breast density as parameter in the evaluation of screening performance. KEY POINTS: ⢠Mammographic density may affect regional breast cancer screening performance. ⢠Volumetric breast density varies across screening areas. ⢠SES is positively associated with breast density. ⢠Implications of volumetric breast density differences need to be studied further.

BACKGROUND: Lifetime risks are often used in communications on cancer to the general public. The most-cited estimate for breast cancer risk (1 in 8 women), however, appears to be outdated. Here we describe the breast cancer burden in the Netherlands over time by means of lifetime and age-conditional risks. The aim is to identify changes in absolute risk of primary breast cancer diagnosis and death. METHODS: Data on breast cancer incidence, mortality and size of the female population were retrieved from the Netherlands Cancer Registry and Statistics Netherlands. Lifetime and age-conditional risks were calculated for 1990, 2000 and 2010 using the life-table method (DevCan software). RESULTS: The lifetime risk of developing breast cancer (ductal carcinoma in situ and invasive) in 1990, 2000 and 2010 was estimated at 10.8 (1 in 9.3 women), 13.5 (1 in 7.4) and 15.2% (1 in 6.6), respectively. Most women were still diagnosed after the age of 50, with the highest risk between 60 and 70 years in 2010. The lifetime risk of breast cancer death was 3.8% (1 in 27) in 2010, which is lower than in 1990 (4.5%; 1 in 22) and 2000 (4.2%; 1 in 24). CONCLUSION: Breast cancer risk has increased to 1 in 6.6 women being diagnosed during their lifetime (invasive cancer only: 1 in 7.4), whereas risk of breast cancer death has decreased from 1 in 22 to 1 in 27 women. To keep cancer management and prevention up-to-date, it remains important to closely monitor the ever-changing breast cancer burden.

BACKGROUND: Patients with facioscapulohumeral dystrophy (FSHD) suffer from slowly progressive muscle weakness. Approximately 20% of FSHD patients end up wheelchair-dependent. FSHD patients benefit from physical activity to maintain their muscle strength as much as possible. The impact of the COVID-19 pandemic on the health of FSHD patients was unknown. OBJECTIVE: This study assessed changes in daily care received, perceived psychosocial stress, and worsening of FSHD complaints in 2020. Furthermore, we compared COVID-19 infection incidence and severity of symptoms between FSHD patients and non-FSHD housemates. METHODS: Three online survey rounds were sent out to all adult participants of the Dutch FSHD registry regarding daily care received, perceived psychosocial stress, COVID-19 infection rate, and COVID-19 symptoms severity. They also included COVID-19-related questions regarding the participants' housemates, which served as control group. RESULTS: Participation rate was 210 (61%), 186 (54%), and 205 (59%) for survey 1, 2, and 3, respectively. Care reduction was reported by 42.7%, 40%, and 28.8% of the participants in the respective surveys. Perceived psychosocial stress increased in 44%, 30%, and 40% of the participants. Compared to the 197 non-FSHD housemates, the 213 FSHD patients reported more possibly COVID-19-related symptoms (27% vs. 39%, p = 0.017) of mostly minimal severity (63%). No difference in (possible) COVID-19 infection incidence rates was found (2.0% vs. 2.8%, p = 0.527). CONCLUSIONS: The COVID-19 pandemic negatively impacted care received and increased perceived psychosocial stress in FSHD patients. However, COVID-19 infection incidence in FSHD patients was similar to their non-FSHD housemates.

Most neuromuscular disorders are rare, but as a group they are not. Nevertheless, epidemiological data of specific neuromuscular disorders are scarce, especially on the incidence. We applied a capture-recapture approach to a nationwide hospital-based dataset and a patients association-based dataset to estimate the annual incidence rates for fifteen neuromuscular disorders in the Netherlands. The annual incidence rates per 100,000 population varied from 0.03/100,000 (95% CI 0.00 â 0.06) for glycogenosis type 5 to 0.9/100,000 (95% confidence interval 0.7 â 1.0) for myotonic dystrophy type 1. The summed annual incidence rate of these disorders was 4.1 per 100,000 per population. Nine of the provided incidence rates were previously unavailable, three rates were similar to the rates in the literature, and three rates were generally higher compared to previous findings but with overlapping confidence intervals. This study provides nationwide incidence rates for fifteen neuromuscular disorders predominantly diagnosed in adult life, nine which were previously unavailable. The capture-recapture approach provided estimates of the total number of individuals with neuromuscular disorders. To complete the gaps in the knowledge of disease frequencies, there is a need for estimates from an automated, obligatory data collection system of diagnosed and newly diagnosed patients with neuromuscular disorders.
RESUMEN
BACKGROUND: Iron catalyzes the formation of free radicals, which could lead to damaged vascular walls and subsequent atherosclerosis. Blood donation decreases iron stores and can thus decrease cardiovascular risk. Even within blood donors, differences in stored iron are observed. This study investigates whether increasing lifetime number of donations decreases the extent of subclinical atherosclerosis within blood donors. STUDY DESIGN AND METHODS: Subclinical atherosclerosis was evaluated in 269 blood donors by measuring intima-media thickness (IMT), pulse-wave velocity (PWV), and ankle-brachial index (ABI). Lifetime number of whole blood donations was categorized into sex-specific donation tertiles. RESULTS: Ferritin and hepcidin were lower in high-frequency donors compared to low-frequency donors. Donors in the third sex-specific donation tertile had on average a 0.3% (95% confidence interval [CI], -3.6 to +3.0%) lower IMT, a 2.1% (95% CI, -3.9 to +8.0%) higher PWV, and a 1.5% (95% CI, -1.4 to +4.5%) higher ABI compared to donors in the first sex-specific donation tertile. CONCLUSION: With such small differences and no consistent trend across donation groups, it cannot be concluded that blood donation has a beneficial effect on the extent of subclinical atherosclerosis.

BACKGROUND: Incomplete cervical cord syndrome without spinal instability is a very devastating event for the patient and the family. It is estimated that up to 25% of all traumatic spinal cord lesions belong to this category. The treatment for this type of spinal cord lesion is still subject of discussion. From a biological point of view early surgery could prevent secondary damage due to ongoing compression of the already damaged spinal cord. Historically, however, conservative treatment was propagated with good clinical results. Proponents for early surgery as well those favoring conservative treatment are still in debate. The proposed trial will contribute to the discussion and hopefully also to a decrease in the variability of clinical practice. METHODS/DESIGN: A randomized controlled trial is designed to compare the clinical outcome of early surgical strategy versus a conservative approach. The primary outcome is clinical outcome according to mJOA. This also measured by ASIA score, DASH score and SCIM III score. Other endpoints are duration of the stay at a high care department (medium care, intensive care), duration of the stay at the hospital, complication rate, mortality rate, sort of rehabilitation, and quality of life. A sample size of 36 patients per group was calculated to reach a power of 95%. The data will be analyzed as intention-to-treat at regular intervals, but the end evaluation will take place at two years post-injury. DISCUSSION: At the end of the study, clinical outcomes between treatments attitudes can be compared. Efficacy, but also efficiency can be determined. A goal of the study is to determine which treatment will result in the best quality of life for the patients. This study will certainly contribute to more uniformity of treatment offered to patients with a special sort of spinal cord injury. TRIAL REGISTRATION: Gov: NCT01367405.

OBJECTIVE: Early detection through mammographic screening and various treatment modalities of cancer may have changed life expectancy and cause-specific mortality of breast cancer patients. We aimed to determine the long-term cause of death patterns in screening-detected patients and clinically diagnosed patients in the Netherlands compared with the general population. METHODS: Using data from the Netherlands Cancer Registry and Statistics Netherlands of around 26,000 women, aged 50-75 at diagnosis and surgically treated for invasive breast cancer in 2004-2008, we compared patients with screening-detected and clinically diagnosed cancer for major causes of death until 2020. The expected number of all-cause and cause-specific deaths was calculated using rates of the general population. RESULTS: During the follow-up period, 4310 women died. The age-standardised all-cause mortality ratio for the screening-detected cancer group was 1.41 (95% confidence interval (95% CI), 1.37-1.46). A higher mortality ratio was observed for patients with clinically detected cancer: 2.27 (95% CI, 2.19-2.34). The observed versus expected breast cancer mortality ratio in the screening-detected patient group was 8.92 (95% CI, 8.45-9.40) and 20.23 (19.38-21.09) in the clinical group. Excess mortality was found for lung cancer in both patient groups, and small elevations for circulatory and respiratory disease in the clinically detected group. CONCLUSION: Our results indicate that for the screening group no other causes of death but breast and lung cancer were prominent compared with the general population. The clinical group showed excess mortality for some other causes of death as well, suggesting a less healthy group compared with the general population.

BACKGROUND: Time trend analysis of cutaneous melanoma (CM) mortality in fair skin populations shows both a gradual decrease and/or an increase. To explain these differences, we analyzed long-term time trends in the incidence of the most common histological subtypes of CM: superficial spreading melanoma (SSM), lentigo maligna melanoma (LMM), and nodular melanoma (NM). METHODS: Using data from the Netherlands Cancer Registry and Statistics Netherlands, the number and rates of cases diagnosed with SSM, LLM, and NM from 1989 to 2016 were analyzed by age, calendar period, and birth cohort of people born in successive periods from 1925 to 1973. RESULTS: Primary CM was diagnosed in 52,000 men and 66,588 women in the study period. The annual age-standardized incidence rate increased three-fold from 14 to 42 per 100,000 person-years. The most common subtype was SSM (50%), followed by LMM (23%) and NM (14%). Age-specific subtype rates showed an upward trend over time for both men and women. Younger birth cohorts had higher rates of SSM and LMM diagnosis than older birth cohorts. This birth cohort pattern was not observed for NM. CONCLUSIONS: We observed a strong increase in the melanoma epidemic curves in the light-skinned Dutch population over the last three decades. This increase is explained by younger generations having higher rates of SSM and LMM than older generations.

BACKGROUND: Determining readiness to return to sport after anterior cruciate ligament (ACL) reconstruction is challenging. OBJECTIVES: To develop models to predict initial (directly after rehabilitation) and sustainable (one year after rehabilitation) return to sport and performance in individuals after ACL reconstruction. METHODS: We conducted a multicentre, prospective cohort study and included 208 participants. Potential predictors - demographics, pain, effusion, knee extension, muscle strength tests, jump tasks and three sport-specific questionnaires - were measured at the end of rehabilitation and 12 months post discharge from rehabilitation. Four prediction models were developed using backward logistic regression. All models were internally validated by bootstrapping. RESULTS: All 4 models shared 3 predictors: the participant's goal to return to their pre-injury level of sport, the participant's psychological readiness and ACL injury on the non-dominant leg. Another predictor for initial return to sport was no knee valgus, and, for sustainable return to sport, the single-leg side hop. Bootstrapping shrinkage factor was between 0.91 and 0.95, therefore the models' properties were similar before and after internal validation. The areas under the curve of the models ranged from 0.74 to 0.86. Nagelkerke's R2 varied from 0.23 to 0.43 and the Hosmer-Lemeshow test results varied from 2.7 (p = 0.95) to 8.2 (p = 0.41). CONCLUSION: Initial and sustainable return to sport and performance after anterior cruciate ligament reconstruction rehabilitation can be easily predicted by the sport goal formulated by the individual, the individual's psychological readiness, and whether the affected leg is the dominant or non-dominant leg.
