Impact of different age ranges on the benefits and harms of the breast cancer screening programme by the EU-TOPIA tool.

BACKGROUND: The recommendation for the implementation of mammography screening in women aged 45-49 and 70-74 is conditional with moderate certainty of the evidence. The aim of this study is to simulate the long-term outcomes (2020-50) of using different age range scenarios in the breast cancer screening programme of the Valencia Region (Spain), considering different programme participation rates. METHODS: Three age range scenarios (S) were simulated with the EU-TOPIA tool, considering a biennial screening interval: S1, 45-69 years old (y); S2, 50-69 y and S3, 45-74 y. Simulations were performed for four participation rates: A = current participation (72.7%), B = +5%, C = +10% and D = +20%. Considered benefits: number (N°) of in situ and invasive breast cancers (BC) (screen vs. clinically detected), N° of BC deaths and % BC mortality reduction. Considered harms: N° of false positives (FP) and % overdiagnosis. RESULTS: The results showed that BC mortality decreased in all scenarios, being higher in S3A (32.2%) than S1A (30.6%) and S2A (27.9%). Harms decreased in S2A vs. S1A (N° FP: 236 vs. 423, overdiagnosis: 4.9% vs. 5.0%) but also benefits (BC mortality reduction: 27.9% vs. 30.6%, N° screen-detected invasive BC 15/28 vs. 18/25). In S3A vs. S1A, an increase in benefits was observed (BC mortality reduction: 32.2% vs. 30.6%), N° screen-detected in situ B: 5/2 vs. 4/3), but also in harms (N° FP: 460 vs. 423, overdiagnosis: 5.8% vs. 5.0%). Similar trends were observed with increased participation. CONCLUSIONS: As the age range increases, so does not only the reduction in BC mortality, but also the probability of FP and overdiagnosis.

ORPHAcodes use for the coding of rare diseases: comparison of the accuracy and cross country comparability.

BACKGROUND: Estimates of rare disease (RD) population impact in terms of number of affected patients and accurate disease definition is hampered by their under-representation in current coding systems. This study tested the use of a specific RD codification system (ORPHAcodes) in five European countries/regions (Czech Republic, Malta, Romania, Spain, Veneto region-Italy) across different data sources over the period January 2019-September 2021. RESULTS: Overall, 3133 ORPHAcodes were used to describe RD diagnoses, mainly corresponding to the disease/subtype of disease aggregation level of the Orphanet classification (82.2%). More than half of the ORPHAcodes (53.6%) described diseases having a very low prevalence (< 1 case per million), and most commonly captured rare developmental defects during embryogenesis (31.3%) and rare neurological diseases (17.6%). ORPHAcodes described disease entities more precisely than corresponding ICD-10 codes in 83.4% of cases. CONCLUSIONS: ORPHAcodes were found to be a versatile resource for the coding of RD, able to assure easiness of use and inter-country comparability across population and hospital databases. Future research on the impact of ORPHAcoding as to the impact of numbers of RD patients with improved coding in health information systems is needed to inform on the real magnitude of this public health issue.

Causes of death in children with congenital anomalies up to age 10 in eight European countries.

BACKGROUND: Congenital anomalies (CAs) increase the risk of death during infancy and childhood. This study aimed to evaluate the accuracy of using death certificates to estimate the burden of CAs on mortality for children under 10 years old. METHODS: Children born alive with a major CA between 1 January 1995 and 31 December 2014, from 13 population-based European CA registries were linked to mortality records up to their 10th birthday or 31 December 2015, whichever was earlier. RESULTS: In total 4199 neonatal, 2100 postneonatal and 1087 deaths in children aged 1-9 years were reported. The underlying cause of death was a CA in 71% (95% CI 64% to 78%) of neonatal and 68% (95% CI 61% to 74%) of postneonatal infant deaths. For neonatal deaths the proportions varied by registry from 45% to 89% and by anomaly from 53% for Down syndrome to 94% for tetralogy of Fallot. In children aged 1-9, 49% (95% CI 42% to 57%) were attributed to a CA. Comparing mortality in children with anomalies to population mortality predicts that over 90% of all deaths at all ages are attributable to the anomalies. The specific CA was often not reported on the death certificate, even for lethal anomalies such as trisomy 13 (only 80% included the code for trisomy 13). CONCLUSIONS: Data on the underlying cause of death from death certificates alone are not sufficient to evaluate the burden of CAs on infant and childhood mortality across countries and over time. Linked data from CA registries and death certificates are necessary for obtaining accurate estimates.

Oesophageal Atresia: Prevalence in the Valencian Region (Spain) and Associated Anomalies.

The objective was to determine the prevalence of oesophageal atresia (OA) and describe the characteristics of OA cases diagnosed before the first year of life, born between 2007 and 2019, and residents in the Valencian Region (VR), Spain. Live births (LB), stillbirths (SB), and termination of pregnancy for fetal anomaly (TOPFA) diagnosed with OA were selected from the Congenital Anomalies population-based Registry of VR (RPAC-CV). The prevalence of OA per 10,000 births with 95% confidence interval was calculated, and socio-demographic and clinical variables were analyzed. A total of 146 OA cases were identified. The overall prevalence was 2.4/10,000 births, and prevalence by type of pregnancy ending was 2.3 in LB and 0.03 in both SB and TOPFA. A mortality rate of 0.03/1000 LB was observed. A relationship was found between case mortality and birth weight (p-value < 0.05). OA was primarily diagnosed at birth (58.2%) and 71.2% of the cases were associated with another congenital anomaly, mainly congenital heart defects. Significant variations in the prevalence of OA in the VR were detected throughout the study period. In conclusion, a lower prevalence in SB and TOPFA was identified compared to EUROCAT data. As several studies have identified, an association between OA cases and birth weight was found.

[Diagnostic delay in rare diseases: between fear and resilience]. / Demora diagnóstica en enfermedades raras: entre el miedo y la resiliencia.

OBJECTIVE: To describe the impact of diagnosis delay in rare diseases and analyze psychosocial needs related to this delay in patients. METHOD: The qualitative approach has been used by conducting online group interviews with patients and family members in the Valencian Region (Spain) and a content analysis has been carried out. Two categories were differentiated: with diagnostic delay of 1 year or more and without diagnostic delay. Five interviews were conducted with a total of 25 participants. RESULTS: The content analysis showed unequal aspects vs. common aspects, in persons with or without diagnostic delay. People with delay expressed the need to feel supported in order to live with continuous uncertainty. People without delay verbalized the importance of adequate communication between patients and professionals. The problems by the COVID-19 were common in both groups; the participants expressed that they did not feel unattended in their disease by the health services. CONCLUSIONS: High resilience and coping capacity has been identified in people with rare disease, regardless of whether they have suffered diagnostic delay or not. The professional psychosocial support during the diagnostic process of these rare diseases is essential.

Demora diagnóstica en enfermedades raras: entre el miedo y la resiliencia / Diagnostic delay in rare diseases: between fear and resilience

Objetivo: Describir el impacto de la demora diagnóstica de enfermedades raras y analizar las necesidades psicosociales de las personas afectadas en relación con dicha demora. Método: Se ha empleado el enfoque cualitativo mediante la realización de entrevistas grupales online a pacientes y familiares en la Comunitat Valenciana (España) y se ha efectuado un análisis de contenido. Se diferenciaron dos categorías: con demora diagnóstica de 1 año o más y sin demora diagnóstica. Se realizaron cinco entrevistas en las que participaron un total de 25 personas. Resultados: El análisis mostró aspectos desiguales frente a aspectos comunes, en personas con o sin demora diagnóstica. Las personas con demora manifestaron la necesidad de sentirse «sostenidas» para convivir con una incertidumbre continua. Las personas sin demora verbalizaron la importancia de una adecuada comunicación entre pacientes y profesionales. Los problemas surgidos por la COVID-19 fueron comunes en ambos grupos, y las personas participantes expresaron no sentirse desatendidas en su enfermedad por los servicios sanitarios durante la pandemia. Conclusiones: Se ha observado una gran capacidad de resiliencia y afrontamiento en las personas con enfermedades raras, independientemente de si han sufrido demora diagnóstica o no. El apoyo psicosocial profesionalizado durante el proceso de diagnóstico de estas enfermedades minoritarias es esencial. (AU)

Rare Diseases: Needs and Impact for Patients and Families: A Cross-Sectional Study in the Valencian Region, Spain.

Families with rare diseases (RDs) have unmet needs that are often overlooked by health professionals. Describing these needs and the impact of the disease could improve their medical care. A total of 163 surveys were obtained from patients visiting primary care centres in the Valencian Region (Spain), during 2015-2017, with a confirmed or suspected diagnosis of RD. Of the 84.7% with a confirmed diagnosis, 50.4% had a diagnostic delay exceeding one year, and it was more prevalent among adults (62.2%). Families with paediatric patients were in a worse economic situation, with lower incomes and higher monthly disease-related expenses (€300 on average). These expenses were incurred by 66.5% of families and were mainly for medication (40.3%). Among them, 58.5% reported not being able to afford adjuvant therapies. The disease had an impact on 73.1% of families, especially on their routine and emotional state. Expenses, needs, and impacts were more frequent among families of patients with a history of hospitalisation or deterioration. Patients with delayed diagnosis had a higher consumption of drugs prior to diagnosis. People affected by RDs in the Valencian Region need therapies to improve their autonomy and emotional state. Health professionals should be aware of these needs.

Hospital length of stay among children with and without congenital anomalies across 11 European regions-A population-based data linkage study.

BACKGROUND: Congenital anomalies are a leading cause of childhood morbidity, but little is known about the long-term outcomes. OBJECTIVE: To quantify the burden of disease in childhood for children with congenital anomalies by assessing the risk of hospitalisation, the number of days spent in hospital and proportion of children with extended stays (≥10 days). METHODS: European population-based record-linkage study in 11 regions in eight countries including children with congenital anomalies (EUROCAT children) and without congenital anomalies (reference children) living in the same regions. The children were born between 1995 and 2014 and were followed to their tenth birthday or 31/12/2015. European meta-analyses of the outcome measures were performed by two age groups, <1 year and 1-4 years. RESULTS: 99,416 EUROCAT children and 2,021,772 reference children were linked to hospital databases. Among EUROCAT children, 85% (95%-CI: 79-90%) were hospitalised in the first year and 56% (95%-CI: 51-61%) at ages 1-4 years, compared to 31% (95%-CI: 26-37%) and 25% (95%-CI: 19-31%) of the reference children. Median length of stay was 2-3 times longer for EUROCAT children in both age groups. The percentages of children with extended stays (≥10 days) in the first year were 24% (95%-CI: 20-29%) for EUROCAT children and 1% (95%-CI: 1-2%) for reference children. The median length of stay varied greatly between congenital anomaly subgroups, with children with gastrointestinal anomalies and congenital heart defects having the longest stays. CONCLUSIONS: Children with congenital anomalies were more frequently hospitalised and median length of stay was longer. The outlook improves after the first year. Parents of children with congenital anomalies should be informed about the increased hospitalisations required for their child's care and the impact on family life and siblings, and they should be adequately supported.

Ten-Year Survival of Children With Congenital Anomalies: A European Cohort Study.

OBJECTIVES: To investigate the survival up to age 10 for children born alive with a major congenital anomaly (CA). METHODS: This population-based linked cohort study (EUROlinkCAT) linked data on live births from 2005 to 2014 from 13 European CA registries with mortality data. Pooled Kaplan-Meier survival estimates up to age 10 were calculated for these children (77 054 children with isolated structural anomalies and 4011 children with Down syndrome). RESULTS: The highest mortality of children with isolated structural CAs was within infancy, with survival of 97.3% (95% confidence interval [CI]: 96.6%-98.1%) and 96.9% (95% CI: 96.0%-97.7%) at age 1 and 10, respectively. The 10-year survival exceeded 90% for the majority of specific CAs (27 of 32), with considerable variations between CAs of different severity. Survival of children with a specific isolated anomaly was higher than in all children with the same anomaly when those with associated anomalies were included. For children with Down syndrome, the 10-year survival was significantly higher for those without associated cardiac or digestive system anomalies (97.6%; 95% CI: 96.5%-98.7%) compared with children with Down syndrome associated with a cardiac anomaly (92.3%; 95% CI: 89.4%-95.3%), digestive system anomaly (92.8%; 95% CI: 87.7%-98.2%), or both (88.6%; 95% CI: 83.2%-94.3%). CONCLUSIONS: Ten-year survival of children born with congenital anomalies in Western Europe from 2005 to 2014 was relatively high. Reliable information on long-term survival of children born with specific CAs is of major importance for parents of these children and for the health care professionals involved in their care.

Clarity and consistency in stillbirth reporting in Europe: why is it so hard to get this right?

BACKGROUND: Stillbirth is a major public health problem, but measurement remains a challenge even in high-income countries. We compared routine stillbirth statistics in Europe reported by Eurostat with data from the Euro-Peristat research network. METHODS: We used data on stillbirths in 2015 from both sources for 31 European countries. Stillbirth rates per 1000 total births were analyzed by gestational age (GA) and birthweight groups. Information on termination of pregnancy at ≥22 weeks' GA was analyzed separately. RESULTS: Routinely collected stillbirth rates were higher than those reported by the research network. For stillbirths with a birthweight ≥500 g, the difference between the mean rates of the countries for Eurostat and Euro-Peristat data was 22% [4.4/1000, versus 3.5/1000, mean difference 0.9 with 95% confidence interval (CI) 0.8-1.0]. When using a birthweight threshold of 1000 g, this difference was smaller, 12% (2.9/1000, versus 2.5/1000, mean difference 0.4 with 95% CI 0.3-0.5), but substantial differences remained for individual countries. In Euro-Peristat, missing data on birthweight ranged from 0% to 29% (average 5.0%) and were higher than missing data for GA (0-23%, average 1.8%). CONCLUSIONS: Routine stillbirth data for European countries in international databases are not comparable and should not be used for benchmarking or surveillance without careful verification with other sources. Recommendations for improvement include using a cut-off based on GA, excluding late terminations of pregnancy and linking multiple sources to improve the quality of national databases.

The ERA Registry Annual Report 2019: summary and age comparisons.

BACKGROUND: Data on renal replacement therapy (RRT) for end-stage renal disease were collected by the European Renal Association (ERA) Registry via national and regional renal registries in Europe and countries bordering the Mediterranean Sea. This article provides a summary of the 2019 ERA Registry Annual Report, including data from 34 countries and additional age comparisons. METHODS: Individual patient data for 2019 were provided by 35 registries and aggregated data by 17 registries. Using these data, the incidence and prevalence of RRT, the kidney transplantation activity and the survival probabilities were calculated. RESULTS: In 2019, a general population of 680.8 million people was covered by the ERA Registry. Overall, the incidence of RRT was 132 per million population (p.m.p.). Of these patients, 62% were men, 54% were ≥65 years of age and 21% had diabetes mellitus as primary renal disease (PRD), and 84% had haemodialysis (HD), 11% had peritoneal dialysis (PD) and 5% had pre-emptive kidney transplantation as an initial treatment modality. The overall prevalence of RRT on 31 December 2019 was 893 p.m.p., with 58% of patients on HD, 5% on PD and 37% living with a kidney transplant. The overall kidney transplant rate was 35 p.m.p. and 29% of the kidney grafts were from a living donor. The unadjusted 5-year survival probability was 42.3% for patients commencing dialysis, 86.6% for recipients of deceased donor grafts and 94.4% for recipients of living donor grafts in the period 2010-14. When comparing age categories, there were substantial differences in the distribution of PRD, treatment modality and kidney donor type, and in the survival probabilities.

Incidence of Kidney Replacement Therapy and Subsequent Outcomes Among Patients With Systemic Lupus Erythematosus: Findings From the ERA Registry.

RATIONALE & OBJECTIVE: There is a dearth of data characterizing patients receiving kidney replacement therapy (KRT) for kidney failure due to systemic lupus erythematosus (SLE) and their clinical outcomes. The aim of this study was to describe trends in incidence and prevalence of KRT among these patients as well as to compare their outcomes versus those of patients treated with KRT for diseases other than SLE. STUDY DESIGN: Retrospective cohort study based on kidney registry data. SETTING & PARTICIPANTS: Patients recorded in 14 registries of patients receiving KRT that provided data to the European Renal Association Registry between 1992 and 2016. PREDICTOR: SLE as cause of kidney failure. OUTCOMES: Incidence and prevalence of KRT, patient survival while receiving KRT, patient and graft survival after kidney transplant, and specific causes of death. ANALYTICAL APPROACH: Kaplan-Meier methods and Cox regression models were fit to compare patient survival between the SLE and non-SLE groups, overall KRT, dialysis, and patient and graft survival after kidney transplant. RESULTS: In total, 1,826 patients commenced KRT for kidney failure due to SLE, representing an incidence of 0.80 per million population (pmp) per year. The incidence remained stable during the study period (annual percent change, 0.1% [95% CI, -0.6% to 0.8%]). Patient survival among patients with SLE receiving KRT was similar to survival in the comparator group (hazard ratio [HR], 1.11 [95% CI, 0.99-1.23]). After kidney transplant, the risk of death was greater among patients with SLE than among patients in the comparator group (HR, 1.25 [95% CI, 1.02-1.53]), whereas the risk of all-cause graft failure was similar (HR, 1.09 [95% CI, 0.95-1.27]). Ten-year patient overall survival during KRT and patient and graft survival after kidney transplant improved over the study period (HRs of 0.71 [95% CI, 0.56-0.91], 0.43 [95% CI, 0.27-0.69], and 0.60 [95% CI, 0.43-0.84], respectively). Patients with SLE receiving KRT were significantly more likely to die of infections (24.8%) than patients in the comparator group (16.9%; P < 0.001). LIMITATIONS: No data were available on extrarenal manifestations of SLE, drug treatments, comorbidities, kidney transplant characteristics, or relapses of SLE. CONCLUSIONS: The prognosis of patients with SLE receiving KRT has improved over time. Survival of patients with SLE who required KRT was similar compared with patients who required KRT for other causes of kidney failure. Survival following kidney transplants was worse among patients with SLE.

Differences in breast cancer-risk factors between screen-detected and non-screen-detected cases (MCC-Spain study).

PURPOSE: The variation in breast cancer (BC)-risk factor associations between screen-detected (SD) and non-screen-detected (NSD) tumors has been poorly studied, despite the interest of this aspect in risk assessment and prevention. This study analyzes the differences in breast cancer-risk factor associations according to detection method and tumor phenotype in Spanish women aged between 50 and 69. METHODS: We examined 900 BC cases and 896 controls aged between 50 and 69, recruited in the multicase-control MCC-Spain study. With regard to the cases, 460 were detected by screening mammography, whereas 144 were diagnosed by other means. By tumor phenotype, 591 were HR+, 153 were HER2+, and 58 were TN. Lifestyle, reproductive factors, family history of BC, and tumor characteristics were analyzed. Logistic regression models were used to compare cases vs. controls and SD vs. NSD cases. Multinomial regression models (controls used as a reference) were adjusted for case analysis according to phenotype and detection method. RESULTS: TN was associated with a lower risk of SD BC (OR 0.30 IC 0.10-0.89), as were intermediate (OR 0.18 IC 0.07-0.44) and advanced stages at diagnosis (OR 0.11 IC 0.03-0.34). Nulliparity in postmenopausal women and age at menopause were related to an increased risk of SD BC (OR 1.60 IC 1.08-2.36; OR 1.48 IC 1.09-2.00, respectively). Nulliparity in postmenopausal women was associated with a higher risk of HR+ (OR 1.66 IC 1.15-2.40). Age at menopause was related to a greater risk of HR+ (OR 1.60 IC 1.22-2.11) and HER2+ (OR 1.59 IC 1.03-2.45) tumors. CONCLUSION: Reproductive risk factors are associated with SD BC, as are HR+ tumors. Differences in BC-risk factor associations according to detection method may be related to prevailing phenotypes among categories.

Geographical Variability in Mortality in Urban Areas: A Joint Analysis of 16 Causes of Death.

The geographical distribution of mortality has frequently been studied. Nevertheless, those studies often consider isolated causes of death. In this work, we aim to study the geographical distribution of mortality in urban areas, in particular, in 26 Spanish cities. We perform an overall study of 16 causes of death, considering that their geographical patterns could be dependent and estimating the dependence between the causes of death. We study the deaths in these 26 cities during the period 1996-2015 at the census tract level. A multivariate disease mapping model is used in order to solve the potential small area estimation problems that these data could show. We find that most of the geographical patterns found show positive correlations. This suggests the existence of a transversal geographical pattern, common to most causes of deaths, which determines those patterns to a higher/lower extent depending on each disease. The causes of death that exhibit that underlying pattern in a more prominent manner are chronic obstructive pulmonary disease (COPD), lung cancer, and cirrhosis for men and cardiovascular diseases and dementias for women. Such findings are quite consistent for most of the cities in the study. The high positive correlation found between geographical patterns reflects the existence of both high and low-risk areas in urban settings, in general terms for nearly all the causes of death. Moreover, the high-risk areas found often coincide with neighborhoods known for their high deprivation. Our results suggest that dependence among causes of death is a key aspect to be taken into account when mapping mortality, at least in urban contexts.

The interoperability between the Spanish version of the International Classification of Diseases and ORPHAcodes: towards better identification of rare diseases.

BACKGROUND: Rare diseases present a wide spectrum of clinical manifestations and severity levels and are often poorly known and underrepresented, making them difficult to classify. Diagnoses are usually coded using the International Classification of Diseases (ICD), with its different versions. In Spain, the ICD-10-ES (stem from the ICD-10-CM-Clinical Modification) is used throughout the National Healthcare System since 2016, indistinctively including rare diseases that often lack a specific code. Orphanet aims to provide high-quality resources on rare diseases. The goal was to interrelate the Orphanet classification with the ICD-10-ES in order to engage a tool to track rare diseases diagnosis and characterize the improvement space for the identification of rare diseases patients in the Spanish Healthcare System. METHODS: 5775 disorder level ORPHAcodes were mapped to ICD-10-ES codes by comparing the descriptors associated in both classifications. ORPHAcodes were then clustered based on their assigned ICD-10-ES chapter and the redundancy of each individual ICD-10-ES code was calculated by counting the ORPHAcodes they mapped to. Three groups were established: Group 1 (1 ORPHAcode per ICD-10-ES), Group 2 (between 2-49 ORPHAcodes per ICD-10-ES) and Group 3 (≥ 50 ORPHAcodes per ICD-10-ES). RESULTS: Equivalences to 1700 ICD-10-ES codes were established for 5664 ORPHAcodes. The ORPHAcodes distribution within the ICD-10-ES showed an aggregation in the "Q" (> 40%), "G" (> 14%), and "E" (12%) chapters. The availability of ICD-10-ES codes to map ORPHAcodes reached its lowest at the "G" and "Q" chapters with less than 0.2 ICD-10-ES codes available per ORPHAcode. Global ICD-10-ES codes redundancy analysis revealed that only 1055 of the equivalences pertain to group 1. Group 2 contained 3358 equivalences with 634 ICD-10-ES codes while 1322 equivalences were group 3 (11 ICD-10-ES). Within ICD-10-ES chapters, "G" and "Q" contained over 30% and 45% of their own equivalences in the highest redundancy level (group 3) respectively, but under 10% one to one equivalences each (group 1). CONCLUSIONS: ICD-10-ES codes have not enough specificity to identify rare diseases. Direct mapping between ICD and ORPHAcodes or the integration of ORPHAcodes at the healthcare system for diagnoses codification would enable better detection and epidemiological analysis of rare diseases.

[Magnitude and factors associated with the solitary death phenomenon of the elderly in the Valencian Community.] / Magnitud y factores asociados al fenómeno de la muerte solitaria del anciano en la Comunidad Valenciana.

OBJECTIVE: In the Valencian Community 23% of the elderly people live alone, representing the solitary death among aged persons an unwanted effect of aging. Our aim was to determine the magnitude of this phenomenon and its risk factors in the population over 64 years of the CV during the period 2015-2017. METHODS: Cross-sectional study was carried out. Household deaths of residents over 64 years of the CV during the 2015-2017 period were analyzed, with records on medical and judicial death certificates. Adjusted incidence rates, sociodemographic characteristics and causes of death were described. For the analysis of risk factors, a multivariate logistic regression was performed, taking the adjusted Odds Ratio (OR) as an association measure. A significance level α=0.05 and 95% confidence intervals (CI) were used. RESULTS: 417 cases were found. The adjusted rates were: in 2015, 17.3 (95% CI: 14.7-20.2); in 2016, 14.5 (95% CI: 12.1-17.2); and in 2017, 13.2 (95% CI: 11,0-15.8). The most frequent causes were circulatory (52.5%) and external (19.2%). After adjustment, gender (OR M / H: 2.40; 95% CI: 1.87-3.06), age (OR ≥76 / <76: 4.56; 95% CI: 3.53 -5.90), disability (OR No / Yes: 0.51; 95% CI: 0.31-0.85), season (ref: spring; summer OR: 2.34; 95% CI: 1.63-3 , 37) and population nucleus (rural / urban OR: 2.20; 95% CI 1.58-3.08), remained associated whit the MSA. CONCLUSIONS: The solitary death among aged persons is a phenomenon scarcely studied in our environment from public health. The magnitude in the CV is relevant, with a greater risk in men and at younger ages, as well as in summer and urban areas. Presenting disability represents a certain protection.

OBJETIVO: En la Comunidad Valenciana un 23% de los ancianos viven solos, representando la muerte solitaria del anciano un efecto indeseado del envejecimiento. Nuestro objetivo fue determinar la magnitud de este fenómeno y sus factores de riesgo en la población mayor de 64 años de la CV durante el período 2015-2017. METODOS: Estudio observacional, transversal. Se analizaron las defunciones domiciliarias de residentes mayores de 64 años de la CV durante el período 2015-2017, con datos de los certificados médicos y judiciales de defunción. Se describieron las tasas de incidencia ajustadas, características sociodemográficas y causas de muerte. Para el análisis de factores de riesgo se realizó una regresión logística multivariante tomando como medida de asociación la Razón de Odds (OR) ajustada. Se usó un nivel de significación α=0,05 y unos IC del 95%. RESULTADOS: Se encontraron 417 casos. Las tasas ajustadas fueron: en 2015, 17,3 (IC95%: 14,7-20,2); en 2016, 14,5 (IC95%: 12,1-17,2); y en 2017, 13,2 (IC95%: 11,0-15,8). Las causas más frecuentes fueron circulatorias (52,5%) y externas (19,2%). Los factores asociados a la MSA fueron el sexo (OR M/H: 2,40; IC95%: 1,87-3,06), edad (OR ≥76/<76: 4,56; IC95%: 3,53-5,90), discapacidad (OR No/Sí: 0,51; IC95%: 0,31-0,85), estación (ref: primavera; OR verano: 2,34; IC95%: 1,63-3,37) y núcleo de población (OR rural/urbano: 2,20; IC95%1,58-3,08). CONCLUSIONES: La magnitud de la muerte en solitario en la Comunidad Valenciana es relevante, existiendo un mayor riesgo en hombres y a edades más tempranas, así como en verano y áreas urbanas. Presentar discapacidad representa una cierta protección.

The ERA-EDTA Registry Annual Report 2018: a summary.

BACKGROUND: The European Renal Association - European Dialysis and Transplant Association (ERA-EDTA) Registry collects data on kidney replacement therapy (KRT) via national and regional renal registries in Europe and countries bordering the Mediterranean Sea. This article summarizes the 2018 ERA-EDTA Registry Annual Report, and describes the epidemiology of KRT for kidney failure in 34 countries. METHODS: Individual patient data on patients undergoing KRT in 2018 were provided by 34 national or regional renal registries and aggregated data by 17 registries. The incidence and prevalence of KRT, the kidney transplantation activity and the survival probabilities of these patients were calculated. RESULTS: In 2018, the ERA-EDTA Registry covered a general population of 636 million people. Overall, the incidence of KRT for kidney failure was 129 per million population (p.m.p.), 62% of patients were men, 51% were ≥65 years of age and 20% had diabetes mellitus as cause of kidney failure. Treatment modality at the onset of KRT was haemodialysis (HD) for 84%, peritoneal dialysis (PD) for 11% and pre-emptive kidney transplantation for 5% of patients. On 31 December 2018, the prevalence of KRT was 897 p.m.p., with 57% of patients on HD, 5% on PD and 38% living with a kidney transplant. The transplant rate in 2018 was 35 p.m.p.: 68% received a kidney from a deceased donor, 30% from a living donor and for 2% the donor source was unknown. For patients commencing dialysis during 2009-13, the unadjusted 5-year survival probability was 42.6%. For patients receiving a kidney transplant within this period, the unadjusted 5-year survival probability was 86.6% for recipients of deceased donor grafts and 93.9% for recipients of living donor grafts.

[Wilson's disease in Spain: validation of sources of information used by the Rare Diseases Registries]. / Enfermedad de Wilson en España: validación de fuentes utilizadas por los Registros de Enfermedades Raras.

OBJECTIVE: To evaluate the sources of information used by the Regional Population-based Registries of Rare Diseases (RRD) for Wilson's Disease identification in Spain; to calculate its prevalence and mortality; and to describe the sociodemographic characteristics of those affected. METHOD: Cross-sectional epidemiological study, period 2010-2015. Possible cases were identified by codes 275.1 (ICD-9-CM), E83.0 (ICD-10) and 905 (ORPHAcode) in: 15 participating RRD and the Rare Disease Patients Registry of the Carlos III Health Institute. The diagnoses were confirmed through a clinical documentation review. The positive predictive value (PPV) of the sources of information used by RRD and their combinations were obtained. The prevalence, mortality and the distribution of sociodemographic characteristics were calculated. RESULTS: The Hospital Discharge Database (HDD) was the most used source by the RRD (PPV=39.4%), followed by the Orphan Drugs Registry (ODR) (PPV=81.9%). The Clinical History of Primary Care (PC) obtains PPV=55.9%. The combinations with highest PPV were the ODR with HDD (PPV=95.8%) and the ODR with PC (PPV=92.9%). 514 cases were confirmed, 57.2% men, with a median age of diagnosis of 21.3 years. The prevalence was 1.64/100,000 inhabitants in 2015 and mortality rate was 3.0%, being both higher in men. CONCLUSIONS: Incorporation of ODR and PC into the RRD is recommended, as its combination and ODR with HDD could be used as an automatic validation criterion for Wilson's disease. The prevalence obtained was similar to that of countries close to Spain.

Supplemented ERA-EDTA Registry data evaluated the frequency of dialysis, kidney transplantation, and comprehensive conservative management for patients with kidney failure in Europe.

The aims of this study were to determine the frequency of dialysis and kidney transplantation and to estimate the regularity of comprehensive conservative management (CCM) for patients with kidney failure in Europe. This study uses data from the ERA-EDTA Registry. Additionally, our study included supplemental data from Armenia, Germany, Hungary, Ireland, Kosovo, Luxembourg, Malta, Moldova, Montenegro, Slovenia and additional data from Israel, Italy, Slovakia using other information sources. Through an online survey, responding nephrologists estimated the frequency of CCM (i.e. planned holistic care instead of kidney replacement therapy) in 33 countries. In 2016, the overall incidence of replacement therapy for kidney failure was 132 per million population (pmp), varying from 29 (Ukraine) to 251 pmp (Greece). On 31 December 2016, the overall prevalence of kidney replacement therapy was 985 pmp, ranging from 188 (Ukraine) to 1906 pmp (Portugal). The prevalence of peritoneal dialysis (114 pmp) and home hemodialysis (28 pmp) was highest in Cyprus and Denmark respectively. The kidney transplantation rate was nearly zero in some countries and highest in Spain (64 pmp). In 28 countries with five or more responding nephrologists, the median percentage of candidates for kidney replacement therapy who were offered CCM in 2018 varied between none (Slovakia and Slovenia) and 20% (Finland) whereas the median prevalence of CCM varied between none (Slovenia) and 15% (Hungary). Thus, the substantial differences across Europe in the frequency of kidney replacement therapy and CCM indicate the need for improvement in access to various treatment options for patients with kidney failure.

Anomalías congénitas cardíacas en la Comunitat Valenciana 2007-2014, el registro poblacional de anomalías congénitas / Congenital heart defects in the Valencian Community 2007-2014: The Population-Based Registry Of Congenital Anomalies

Introducción: Las anomalías congénitas cardíacas (ACC) son el tipo de anomalías congénitas (AC) mayores de más prevalencia y gravedad. El objetivo fue determinar la frecuencia y distribución de las ACC en la Comunitat Valenciana desde 2007 hasta 2014, describiendo las características comunes de los pacientes y sus madres. Material y Métodos: Se seleccionaron del Registro poblacional de AC de la Comunitat Valenciana los pacientes con ACC nacidos vivos, nacidos muertos e interrupciones voluntarias del embarazo entre 2007-2014 (códigos Q20-Q26 de la Clasificación Internacional de Enfermedades 10.ª Revisión, Asociación Pediátrica Británica). Se calculó la prevalencia por 10.000 nacidos para el total de ACC y sus subtipos, se describió su evolución temporal y distribución geográfica, y se identificaron las malformaciones no cardíacas asociadas. Resultados: Se identificaron 3.671 pacientes con ACC representando el 38,6% de las AC. La prevalencia fue 91,1/10.000 (IC95%:88,1-94,0) destacando especialmente la comunicación interauricular (48,5/10.000 [IC95%:46,4-50,6]) y la comunicación interventricular (36,1/10.000 (IC95%: 34,3-38,0)). La provincia de Castellón obtuvo la prevalencia más alta (137,8/10.000 [IC95%:127,5-148,1]). El sexo de los pacientes fue 47,3% niños y 44,3% niñas. El 90,9% de los pacientes nacieron vivos y el 65,6% fueron diagnosticados al nacimiento. Las malformaciones asociadas a las ACC más frecuentes fueron las musculoesqueléticas y el 19,2% tenían síndromes asociados. La diabetes mellitus, hipotiroidismo e infecciones del tracto urinario fueron las principales patologías maternas. Conclusiones: Las prevalencias de ACC y comunicación interauricular identificadas son superiores a las europeas, mientras que la de la comunicación interventricular es similar. Las malformaciones musculoesqueléticas fueron las AC no cardiacas más relacionadas con las ACC

Introduction: Congenital heart defects (CHDs) are the most prevalent and severe type of major congenital anomalies (CAs). The objective of this study was to determine the frequency and distribution of CHDs in the Valencian Region from 2007 to 2014, describing common characteristics of the patients and their mothers. Material and Methods: We retrieved data on CHDs in live births, stillbirths and cases of termination of pregnancy for fetal anomaly between 2007 and 2014 (codes Q20-Q26 in the 10th Revision of the International Classification of Diseases-British Paediatric Association, ICD10-BPA) from the population-based Registry of congenital anomalies of the Valencian Region. We calculated the prevalence per every 10,000 births of CHDs overall and by subtype, analysed temporal trends and the geographic distribution of cases, and documented the presence of associated noncardiac malformations. Results: We identified 3,671 cases of CHD, corresponding to 38.6% of all CAs. The prevalence was 91.1/10,000 (IC 95%: 88.1-94.0) with a predominance of septal defects, chiefly atrial septal defect (48.5/10,000; IC 95%: 46.4-50.6) and ventricular septal defect (36.1/10,000; IC 95%: 34.3-38.0). We found the highest prevalence in the province of Castellon (137.8/10,000; IC 95%: 127.5-148.1). The sex distribution was 47.3% male and 44.3% female. Of all cases, 90.9% corresponded to live births and 65.6% were diagnosed at birth. The most frequent associated extracardiac malformations were musculoskeletal, and 19.2% of patients had syndromes. The most frequent maternal diseases were diabetes mellitus, hypothyroidism and urinary tract infections. Conclusions: The prevalence of CHD and atrial septal defects was higher compared to European data, while the prevalence of ventricular septal defects was similar. Musculoskeletal malformations were the noncardiac CAs most frequently associated with CHDs
