RESUMEN

The objective of this study is to develop and validate a screening instrument for the recognition of child maltreatment in the emergency department (ED). Existing data on screening questions and outcomes (diagnosis of child maltreatment) from three large observational screening studies at eight different EDs in the Netherlands were harmonized. A multivariate logistic regression was performed to develop the Screening instrument for Child Abuse and Neglect (SCAN). The SCAN was validated by performing a cross-validation and calculating the discriminative ability. A total of 24,963 patients were included. Out of the potential screening questions the following questions were included in the final instrument: is the injury compatible with the history, and does it correspond to the child's developmental level? (aOR 10.40, 95% CI 5.69-19.02), was there an unnecessary delay in seeking medical help? (aOR 3.45, 95% CI 1.73-6.88) and is the behaviour/interaction of the child and parents (carers) appropriate? (aOR 14.67, 95% CI 7.93-27.13). The SCAN had a pooled AUC of 0.75 (95% CI 0.63-0.87) in the cross-validation. The question "Are there other signals that make you doubt the safety of the child and/or family?" (available in only one of the original datasets, OR 182.9; 95% CI 102.3-327.4) was by consensus added to the final SCAN. CONCLUSION: This validated and brief Screening instrument for Child Abuse and Neglect (SCAN) is designed to improve early recognition of child maltreatment in the ED. A positive screening result of the SCAN warrants a thorough work-up for child maltreatment, including a top-toe examination, if necessary additional diagnostics and adequate safety measures. WHAT IS KNOWN: • Screening instruments increase the detection of possible cases of child maltreatment in the emergency department and support health care professionals to identify these cases. • The application of different screening instruments led to the need for one brief validated instrument. WHAT IS NEW: • This study presents a validated and brief Screening instrument for Child Abuse and Neglect (SCAN), consisting of four questions. • The SCAN supports professionals in detecting signals of child maltreatment, and a positive screening result should lead to a thorough work-up, including a top-toe examination, complete history, additional diagnostic tests and consultation of a child abuse expert.

RESUMEN

Background: Urogenital schistosomiasis (UgS) is a parasitic disease caused by Schistosoma haematobium and can lead to chronic ill-health. Nigeria is endemic for schistosomiasis, but epidemiology of UgS has not been studied in most states. This study was conceived with the aim to contribute towards an accurate national picture of UgS in Nigeria. The prevalence of UgS and the associated risk factors were for the first time investigated among primary school pupils in Jidawa and Zobiya communities of the Dutse Local Government Area (LGAs) of Jigawa State, Nigeria. Method: Focus group discussions with teachers and parents were conducted. After obtaining written consent from parents, questionnaires were administered to pupils to obtain socio-demographic data and information on water contact activities. Urine samples (279) were collected and processed by the urine filtration technique to evaluate haematuria and the presence of S. haematobium eggs. Results: Prevalences of 65.7% (90/137) and 69.0% (98/142) were recorded in the Jidawa and Zobiya communities, respectively. In both communities, there was a significant association between gender and UgS: 63.3% of the infected pupils were males as compared to 36.7% females (χ2 = 5.42, p = 0.020). Grade 5 students had a significantly higher prevalence (χ2 = 17.919, p = 0.001) (80.0%) compared to those in grades 2, 3, 4, and 6 (63.8%, 66.7%, 61.5%, and 64.6%, respectively). Water contact activities showed that pupils involved in fishing, irrigation, and swimming were at greater risk of becoming infected in Jidawa and Zobiya, with odds ratios (risk factors) of 5.4 (0.994-28.862) and 4.1 (1.709-9.862), respectively (p = 0.05). Conclusion: Both the Jidawa and Zobiya communities of the Dutse LGAs of Jigawa State are hyperendemic for UgS. In collaboration with the State Ministry of Health, mass administration of praziquantel was carried out in the Jidawa and Zobiya communities after this study.

RESUMEN

There are currently screening programmes for breast, cervical and colorectal cancer in many European countries. However, the uptake of cancer screening in general may vary within and between countries. The aim of this study is to assess the inequalities in testing utilization by socio-economic status and whether the amount of inequality varies across European regions. We conducted an analysis based on cross-sectional data from the second wave of the European Health Interview Survey from 2013 to 2015. We analysed the use of breast, cervical, and colorectal cancer testing by socio-economic position (household income, educational level and employment status), socio-demographic factors, self-perceived health and smoking behaviour, by using multinomial logistic models, and inequality measurement based on the Slope index of inequality (SII) and Relative index of inequality (RII). The results show that the utilization of mammography (Odds Ratio (OR) = 0.55, 95% confidence interval (95%CI):0.50-0.61), cervical smear tests (OR = 0.60, 95%CI:0.56-0.65) and colorectal testing (OR = 0.82, 95%CI:0.78-0.86) was overall less likely among individuals within a low household income compared to a high household income. Also, individuals with a non-EU country of birth, low educational level and being unemployed (or retired) were overall less likely to be tested. The income-based inequality in breast (SII = 0.191;RII = 1.260) and colorectal testing utilization (SII = 0.161;RII = 1.487) was the greatest in Southern Europe. For cervical smears, this inequality was greatest in Eastern Europe (SII = 0.122;RII = 1.195). We concluded that there is considerable inequality in the use of cancer tests in Europe, with inequalities associated with household income, educational level, employment status, and country of birth.

RESUMEN

OBJECTIVE: We aim to compare the cost-effectiveness of the old cytology programme with the new high-risk human papillomavirus (hrHPV) screening programme, using performance indicators from the new Dutch hrHPV screening programme. DESIGN: Model-based cost-effectiveness analysis. SETTING: The Netherlands. POPULATION: Dutch 30-year-old unvaccinated females followed up lifelong. METHODS: We updated the microsimulation screening analysis (MISCAN) model using the most recent epidemiological and screening data from the Netherlands. We simulated both screening programmes, using the screening behaviour and costs observed in each programme. Sensitivity analyses were performed on screening behaviour, utility losses and discount rates. MAIN OUTCOME MEASURES: Cervical cancer incidence and mortality rates, number of screening tests and repeat tests, colposcopy referrals by lesion grade, costs from a societal perspective, quality-adjusted life years (QALYs) gained and cost-effectiveness. RESULTS: The new Dutch cervical cancer screening programme decreased the cervical cancer mortality by 4% and the incidence by 1% compared with the old programme. Colposcopy referrals of women without cervical intra-epithelial neoplasia grade 2 or worse, increased by 172%, but 13% more QALYs were still achieved. Total costs were reduced by 21%, mainly due to fewer screening tests. Per QALY gained, the hrHPV programme cost 46% less (€12,225) than the cytology programme (€22,678), and hrHPV-based screening remained more cost-effective in all sensitivity analyses. CONCLUSIONS: The hrHPV-based screening programme was found to be more effective and cost-effective than the cytology programme. Alternatives for the current triage strategy should be considered to lower the number of unnecessary referrals. TWEETABLE ABSTRACT: First results after implementation confirm that HPV screening is more cost-effective than cytology screening.

RESUMEN

INTRODUCTION: European Randomized Study of Screening for Prostate Cancer (ERSPC) mortality results were reported for 7 European countries (excluding France) and showed a significant reduction in Prostate cancer (PCa) mortality. As those results have not been part of the global ERSPC results, it is of interest to report PCa mortality at a median follow-up of 9 years for French section of ERSPC. MATERIAL AND METHODS: Two administrative departments were involved in the study. Only men after randomization in the screening group were invited by mail to be screened by PSA testing with two rounds at 4-6 year intervals. Biopsy was recommended if PSA>=3.0 ng/mL. No information other that the French Association of Urology recommandations on the use of PSA was offered to the control group (own decision of physicians and patients). Follow up was based on cancer registry database. Contamination defined as the receipt of PSA testing in control arm was measured. Poisson regression models were used to estimate the Rate Ratio (RR) of PCa mortality and incidence in the screening vs. control arm. RESULTS: Starting from 2003, 80,696 men aged 55-69 years were included. The percentage of men in the screening arm with at least one PSA test (compliance) was 31%. Compared to the control arm, PCa incidence increased by 10% in the screening arm (RR=1.10; 95% CI=[1.04-1.16], P=0.001), but PCa mortality did not differ (0.222 and 0.215 deaths/1000 person-years; RR=1.03[0.75-1.42], P=0.9). DISCUSSION: Limitations include low participation rate. PSA testing in the control arm was observed in 32% of men (contamination). CONCLUSIONS: Contamination in control group led to no effect of PSA-based screening on prostate cancer mortality at 9 years follow-up. LEVEL OF EVIDENCE: 3.

RESUMEN

Well-known medical herbal compounds including apigenin, daidzein, phyllanthin and tyramine were assessed against Trypanosoma and Leishmania protozoans. Two strains of the bloodstream forms of Trypanosoma brucei: s427-WT and TbAT1-B48, and Leishmania major and Leishmania mexicana promastigotes were utilised. Among selected natural compounds, apigenin and daidzein displayed moderate activity against African trypanosomes with EC50 16 µM for wild-type sensitive control strain. Tyramine was not found to be very active for trypanosomes strains while all compounds were found to have trivial activity for the inhibition of Leishmania mexicana strains.

RESUMEN

AIM: To determine the willingness of women with extremely dense breasts to undergo breast cancer screening with magnetic resonance imaging (MRI) in a research setting, and to examine reasons for women to participate or not. MATERIALS AND METHODS: Between 2011 and 2015, 8,061 women (50-75 years) were invited for supplemental MRI as part of the Dense Tissue and Early Breast Neoplasm Screening (DENSE) trial (ClinicalTrials.gov Identifier: NCT01315015), after a negative screening mammography in the national population-based mammography screening programme. Demographics of participants and non-participants were compared. All invitees were asked to report reasons for (non)participation. Ethical approval was obtained. Participants provided written informed consent. RESULTS: Of the 8,061 invitees, 66% answered that they were interested, and 59% eventually participated. Participants were on average 54-years old (interquartile range: 51-59 years), comparable to women with extremely dense breasts in the population-based screening programme (55 years). Women with higher socio-economic status (SES) were more often interested in participation than women with lower SES (68% versus 59%, p<0.001). The most frequently stated reasons for non-participation were "MRI-related inconveniences and/or self-reported contraindications to MRI" (27%) and "anxiety regarding the result of supplemental screening" (21%). "Expected personal health benefit" (68%) and "contribution to science" (43%) were the most frequent reasons for participation. CONCLUSION: Of women invited for MRI because of extremely dense breasts, 59% participated. Common reasons for non-participation were "MRI-related inconveniences" and "anxiety regarding the result of supplemental screening". In case of future implementation, availability of precise evidence on benefits and harms might reduce this anxiety.

RESUMEN

The population-based Basque Colorectal Cancer (CRC) Screening Programme started in 2009 with a biennial immunochemical quantitative test (FIT) biennial and colonoscopy under sedation in positive cases. The population target of 586,700 residents was from 50 to 69 years old and the total coverage was reached at the beginning of 2014. The aim of our study was to determine possible scenarios in terms of incidence, mortality and reduction of Life-years-Lost (L-y-L) in the medium and long term of CRC. METHODS: Invitations were sent out by the Programme from 2009 to 2014, with combined organizational strategies. Simulation was done by MISCAN-colon (Microsimulation Screening Analysis) over 30 years comparing the results of screening vs no-screening, taking the population-based Cancer Registry into account. Lifetime population and real data from the Programme were used from 2008 to 2012. The model was run differentially for men and women. RESULTS: 924,416 invitations were sent out from 2009 to 2014. The average participation rate was 68.4%, CRC detection rate was 3.4% and the Advanced Adenoma detection rate was 24.0‰, with differences observed in sex and age. Future scenarios showed a higher decrease of incidence (17.2% vs 14.7%), mortality (28.1% vs 22.4%) and L-y-L (22.6% vs 18.4%) in men than women in 2030. CONCLUSIONS: The Basque Country CRC Programme results are aligned to its strategy and comparable to other programmes. MISCAN model was found to be a useful tool to predict the benefits of the programme in the future. The effectiveness of the Programme has not been formally established as case control studies are required to determine long term benefits from the screening strategy.

RESUMEN

Objective To estimate the effect of omitting an individual screen from a child vision screening programme on the detection of amblyopia in the Netherlands. A previous study (Rotterdam Amblyopia Screening Effectiveness Study) suggested that the three screens carried out between 6 and 24 months contributed little. Methods We developed a micro-simulation model that approximated the birth-cohort data from the previous study, in which 2964 children had completed follow-up at age 7, and 100 amblyopia cases were detected. Detailed data on screens, referrals, and orthoptic follow-up, including the cause of amblyopia, were available. The model predicted the number of amblyopia cases detected for each screen and for the entire screening programme, and the effect of omitting screens. Incidence curves for all types of amblyopia caused by strabismus, refractive anomalies or by both were estimated by approximation of the observational data, in conjunction with experts' estimations and the literature. Results We calculated mean actual sensitivity per screen per type of amblyopia, and the effect per screen. Screening at 24 months was found to be least effective. The impact on the screening programme, estimated by summing the effectiveness per screen, omitting the 24-month screen, was a reduction of 3.4% (57 vs. 59 cases) in the number of detected cases of amblyopia at age 5. Conclusion The effectiveness of the Dutch vision screening programme would hardly be affected by omission of the 24-month screening examination. A disinvestment study is warranted.

RESUMEN

Primary outcome of the Dutch-Belgian lung cancer screening trial (NELSON) is lung cancer-specific mortality. Accurate assessment of the cause of death (CoD) is crucial. As death certificates regarding the CoD can be inaccurate, a clinical expert committee (CEC) was formed to assign the CoD. In this study, the medical files of deceased lung cancer patients were reviewed and the outcomes were compared with official death certificates. The first 266 completed medical files of Dutch deceased participants who were diagnosed with lung cancer during the study or of those with lung cancer on the death certificate were selected and blinded towards arms and patients identity. The end product of the review process consisted of six possible categories which defined the graduation of certainty that lung cancer was the primary CoD. The percentage agreement and the Cohen's kappa statistics between the two CEC-memberswere calculated. The sensitivity and specificity of the official death certificates were determined. The results indicated that, the overall concordance and the Cohen's kappa between the CEC-memberswere 86.1% and 0.57(0.45-0.69, p<0.001), respectively. This level increased with the numbers of cases evaluated. The sensitivity and the specificity of the official death certificate were 92.6% and 98.8%; 6.5% cases were reclassified to lung cancer specific death, which is lower than in the National Lung Screening trial(22.0%). Concluding, each death should be reviewed by at least two members. So far, in the NELSON trial, possible biases related to lung cancer death seem relatively small.

RESUMEN

OBJECTIVES: Cigarette smoking negatively affects bone quality and increases fracture risk. Little is known on the effect of smoking cessation and computed tomography (CT)-derived bone mineral density (BMD) decline in the spine. We evaluated the association of current and former smoking with BMD decline after 3-year follow-up. METHODS: Male current and former smokers participating in a lung cancer screening trial who underwent baseline and 3-year follow-up CT were included. BMD was measured by manual placement of a region of interest in the first lumbar vertebra and expressed in Hounsfield Unit (HU). Multiple linear regression analysis was used to evaluate the association between pack years smoked and smoking status with BMD decline. RESULTS: 408 participants were included with median (25th-75th percentile) age of 59.4 (55.9-63.5) years. At the start of the study, 197 (48.3%) participants were current smokers and 211 (51.7%) were former smokers and had a similar amount of pack years. Current smokers had quit smoking for 6 (4-8) years prior to inclusion. There was no difference in BMD between current and former smokers at baseline (109±34 HU vs. 108±32 HU, p=0.96). At 3-year follow-up, current smokers had a mean BMD decline of -3±13 HU (p=0.001), while BMD in former smokers did not change as compared to baseline (1±13 HU, p=0.34). After adjustment for BMD at baseline and body mass index, current smoking was independently associated with BMD decline (-3.8 HU, p=0.003). Age, pack years, and the presence of a fracture at baseline did not associate with BMD decline. CONCLUSIONS: Current smokers showed a more rapid BMD decline over a 3-year period compared to former smokers. This information might be important to identify subjects at risk for osteoporosis and emphasizes the importance of smoking cessation in light of BMD decline.

RESUMEN

The Norwegian Breast Cancer Screening Programme (NBCSP) has a nation-wide coverage since 2005. All women aged 50-69 years are invited biennially for mammography screening. We evaluated breast cancer mortality reduction and performed a cost-effectiveness analysis, using our microsimulation model, calibrated to most recent data. The microsimulation model allows for the comparison of mortality and costs between a (hypothetical) situation without screening and a situation with screening. Breast cancer incidence in Norway had a steep increase in the early 1990s. We calibrated the model to simulate this increase and included recent costs for screening, diagnosis and treatment of breast cancer and travel and productivity loss. We estimate a 16% breast cancer mortality reduction for a cohort of women, invited to screening, followed over their complete lifetime. Cost-effectiveness is estimated at NOK 112,162 per QALY gained, when taking only direct medical costs into account (the cost of the buses, examinations, and invitations). We used a 3.5% annual discount rate. Cost-effectiveness estimates are substantially below the threshold of NOK 1,926,366 as recommended by the WHO guidelines. For the Norwegian population, which has been gradually exposed to screening, breast cancer mortality reduction for women exposed to screening is increasing and is estimated to rise to ∼30% in 2020 for women aged 55-80 years. The NBCSP is a highly cost-effective measure to reduce breast cancer specific mortality. We estimate a breast cancer specific mortality reduction of 16-30%, at the cost of 112,162 NOK per QALY gained.

RESUMEN

PURPOSE: This implementation study evaluated orthoptists' use of an educational cartoon ("the Patchbook") and other measures to improve compliance with occlusion therapy for amblyopia. METHODS: Participating orthoptists provided standard orthoptic care for one year, adding the Patchbook in the second year. They attended courses on compliance and intercultural communication by communication skills training. Many other compliance-enhancing measures were initiated. Orthoptists' awareness, attitude, and activities regarding noncompliance were assessed through interviews, questionnaires, and observations. Their use of the Patchbook was measured. The study was performed in low socio-economic status (SES) areas and in other areas in the Netherlands. It was attempted to integrate education on compliance into basic and continuing orthoptic training. RESULTS: The Patchbook was used by all 9 orthoptists who participated in low-SES areas and 17 of 23 orthoptists in other areas. Courses changed awareness and attitude about compliance, but this was not sustained. Although orthoptists estimated compliance during patching at 70%, three-quarters never suspected noncompliance during a full day of observation in any of their patients. Explanations to parents who spoke Dutch poorly were short. In the second year, explanations to children were longer. Implementation of all 7 additional compliance-enhancing measures failed. Education on compliance was not integrated into orthoptists' training. CONCLUSION: Almost all orthoptists used the Patchbook and, as another study demonstrated, it proved to be very effective, especially in low-SES areas. Duration of explanation was inversely proportional to parents' fluency in Dutch. Noncompliance was rarely suspected by orthoptists. Although 7 additional compliance-enhancing measures had been conceived and planned with the best intentions, they were not realized. These required extra, unpaid time from the orthoptists, which is especially scarce in hospitals in low-SES areas where the educational cartoon is most needed.

RESUMEN

BACKGROUND: The incidence of ductal carcinoma in situ (DCIS) has rapidly increased over time. The malignant potential of DCIS is dependent on its differentiation grade. METHODS: Our aim is to determine the distribution of different grades of DCIS among women screened in the mass screening programme, and women not screened in the mass screening programme, and to estimate the amount of overdiagnosis by grade of DCIS. We retrospectively included a population-based sample of 4232 women with a diagnosis of DCIS in the years 2007-2009 from the Nationwide network and registry of histopathology and cytopathology in the Netherlands. Excluded were women with concurrent invasive breast cancer, lobular carcinoma in situ and no DCIS, women recently treated for invasive breast cancer, no grade mentioned in the record, inconclusive record on invasion, and prevalent DCIS. The screening status was obtained via the screening organisations. The distribution of grades was incorporated in the well-established and validated microsimulation model MISCAN. RESULTS: Overall, 17.7 % of DCIS were low grade, 31.4 % intermediate grade, and 50.9 % high grade. This distribution did not differ by screening status, but did vary by age. Older women were more likely to have low-grade DCIS than younger women. Overdiagnosis as a proportion of all cancers in women of the screening age was 61 % for low-grade, 57 % for intermediate-grade, 45 % for high-grade DCIS. For women age 50-60 years with a high-grade DCIS this overdiagnosis rate was 21-29 %, compared to 50-66 % in women age 60-75 years with high-grade DCIS. CONCLUSIONS: Amongst the rapidly increasing numbers of DCIS diagnosed each year is a significant number of overdiagnosed cases. Tailoring treatment to the probability of progression is the next step to preventing overtreatment. The basis of this tailoring could be DCIS grade and age.

RESUMEN

In this study, the effect of strapping rowers to their sliding seat on performance during 75 m on-water starting trials was investigated. Well-trained rowers performed 75 m maximum-effort starts using an instrumented single scull equipped with a redesigned sliding seat system, both under normal conditions and while strapped to the sliding seat. Strapping rowers to their sliding seat resulted in a 0.45 s lead after 75 m, corresponding to an increase in average boat velocity of about 2.5%. Corresponding effect sizes were large. No significant changes were observed in general stroke cycle characteristics. No indications of additional boat heaving and pitching under strapped conditions were found. The increase in boat velocity is estimated to correspond to an increase in average mechanical power output during the start of on-water rowing between 5% and 10%, which is substantial but smaller than the 12% increase found in a previous study on ergometer starting. We conclude that, after a very short period of adaptation to the strapped condition, single-scull starting performance is substantially improved when the rower is strapped to the sliding seat.

RESUMEN

OBJECTIVES: In 2013, the Swiss Medical Board (SMB) concluded that for three breast cancer screens over 13 years in Switzerland, cost-effectiveness was negative, with no additional benefits in quality-adjusted life-years gained. We compared these suggested predicted effects with other estimates. METHODS: We used an extensively validated model on the natural history of breast cancer in Switzerland, comparing a 13-year time frame, a life-time perspective, and a continuous screening programme, per 10,000 Swiss women. Both approaches used the Swedish randomized controlled trials for the theoretical effect. RESULTS: Over 13 years, both approaches yield comparable life-years gained (56 versus 67), but in expectation in 10,000 women's lifetimes 444 life-years are gained, and in a continuous screening programme (instead of three screens) 839 years. The SMB estimate of 56 life-years gained is counterweighted by 57 negative quality of life adjusted years, primarily resulting from a 5% annual loss for 10% of women, being false-positive results. International literature is consistent with more than four times lower losses on false-positives. The estimate of overdiagnosed cases in the 13-year time frame was four times higher than in the long-term perspective. CONCLUSIONS: By restricting life-years gained to a 13-year time frame the SMB prediction on benefits of mammography screening is unrealistically low. Predicting long-term harms and benefits, specifically tailored to observations, regarding the clinical situation before screening commences, and possible data during a screening programme, are crucial for women, professionals, and policymakers.
