Benefits, pitfalls, and future design of population-based registers in neurodegenerative disease.

Population-based disease registers identify and characterize all cases of disease, including those that might otherwise be neglected. Prospective population-based registers in neurodegeneration are necessary to provide comprehensive data on the whole phenotypic spectrum and can guide planning of health services. With the exception of the rare disease amyotrophic lateral sclerosis, few complete population-based registers exist for neurodegenerative conditions. Incomplete ascertainment, limitations and uncertainty in diagnostic categorization, and failure to recognize sources of bias reduce the accuracy and usefulness of many registers. Common biases include population stratification, the use of prevalent rather than incident cases in earlier years, changes in disease understanding and diagnostic criteria, and changing demographics over time. Future registers are at risk of funding shortfalls and changes to privacy legislation. Notwithstanding, as heterogeneities of clinical phenotype and disease pathogenesis are increasingly recognized in the neurodegenerations, well-designed longitudinal population-based disease registers will be an essential requirement to complete clinical understanding of neurodegenerative diseases.

A methodological approach for assessing the uptake of core outcome sets using ClinicalTrials.gov: findings from a review of randomised controlled trials of rheumatoid arthritis.

Objective To assess the uptake of the rheumatoid arthritis core outcome set using a new assessment method of calculating uptake from data in clinical trial registry entries.Design Review of randomised trials.Setting ClinicalTrials.gov.Subjects 273 randomised trials of drug interventions for the treatment of rheumatoid arthritis and registered in ClinicalTrials.gov between 2002 and 2016. Full publications were identified for completed studies from information in the trial registry or from an internet search using Google and the citation database Web of Science.Main outcome measure The percentage of trials reporting or planning to measure the rheumatoid arthritis core outcome set calculated from the information presented in the trial registry and compared with the percentage reporting the rheumatoid arthritis core outcome set in the resulting trial publications.Results The full rheumatoid arthritis core outcome set was reported in 81% (116/143) of trials identified on the registry as completed (or terminated) for which results were found in either the published literature or the registry. For trials identified on the registry as completed (or terminated), using information only available in the registry gives an estimate for uptake of 77% (145/189).Conclusions The uptake of the rheumatoid arthritis core outcome set in clinical trials has continued to increase over time. Using the information on outcomes listed for completed or terminated studies in a trial registry provides a reasonable estimate of the uptake of a core outcome set and is a more efficient and up-to-date approach than examining the outcomes in published trial reports. The method proposed may provide an efficient approach for an up-to-date assessment of the uptake of the 300 core outcome sets already published.

Accuracy of ethnicity data recorded in hospital-based patient clinical records and the Australia and New Zealand Dialysis and Transplant Registry.

Sustained health inequities are experienced by indigenous and minority populations. Accurate ethnicity data are fundamental to healthcare planning and provision and monitoring of health outcomes to address such inequities. This study investigated the accuracy of ethnicity data in a large clinical registry of end-stage kidney disease patients (the Australia and New Zealand Dialysis and Transplant Registry; ANZDATA) and hospital-based patient clinical records compared with self-reported ethnicity data collected in the 'Dialysis Outcomes in those aged ≥65 years' (DOS65+) study.

Association of body mass index with clinical outcomes for in-hospital cardiac arrest adult patients following extracorporeal cardiopulmonary resuscitation.

Obesity might be associated with disturbance of cannulation in situation of extracorporeal cardiopulmonary resuscitation (ECPR). However, limited data are available on obesity in the setting of ECPR. Therefore, we investigated the association between body mass index (BMI) and clinical outcome in patients underwent ECPR.

Low cholesterol level associated with severity and outcome of spontaneous intracerebral hemorrhage: Results from Taiwan Stroke Registry.

The relationship between cholesterol level and hemorrhagic stroke is inconclusive. We hypothesized that low cholesterol levels may have association with intracerebral hemorrhage (ICH) severity at admission and 3-month outcomes. This study used data obtained from a multi-center stroke registry program in Taiwan. We categorized acute spontaneous ICH patients, based on their baseline levels of total cholesterol (TC) measured at admission, into 3 groups with <160, 160-200 and >200 mg/dL of TC. We evaluated risk of having initial stroke severity, with National Institutes of Health Stroke Scale (NIHSS) >15 and unfavorable outcomes (modified Rankin Scale [mRS] score >2, 3-month mortality) after ICH by the TC group. A total of 2444 ICH patients (mean age 62.5±14.2 years; 64.2% men) were included in this study and 854 (34.9%) of them had baseline TC <160 mg/dL. Patients with TC <160 mg/dL presented more often severe neurological deficit (NIHSS >15), with an adjusted odds ratio [aOR] of 1.80; 95% confidence interval [CI], 1.41-2.30), and 3-month mRS >2 (aOR, 1.41; 95% CI, 1.11-1.78) using patients with TC >200 mg/dL as reference. Those with TC >160 mg/dL and body mass index (BMI) <22 kg/m2 had higher risk of 3-month mortality (aOR 3.94, 95% CI 1.76-8.80). Prior use of lipid-lowering drugs (2.8% of the ICH population) was not associated with initial severity and 3-month outcomes. A total cholesterol level lower than 160 mg/dL was common in patients with acute ICH and was associated with greater neurological severity on presentation and poor 3-month outcomes, especially with lower BMI.

Cancer of unknown primary: Registered procedures compared with national integrated cancer pathway for illuminating external validity.

Cancer of unknown primary (CUP) ranges within top 10 cancers in both incidence and mortality. As primary identification is crucial to choosing treatment, guidelines on CUP emphasize the diagnostic strategy. Whether guidelines are complied with, or if they are indeed helpful, is however unclear. We compared procedures performed in suspected CUP patients with recommendations of national guidelines to assess external validity of guidelines.The Danish National Patient Registry (NPR) comprising population data was utilized to identify the suspected CUP patients during 2009 to 2010 and explore exposure to procedures and patient survival. The cohort was investigated in terms of validity of diagnosis through cross-referencing with the Cancer Registry (CR), which served as gold standard for cancer diagnoses and patients' cancer histories.The NPR cohort consisted of 542 patients (275 males, 264 females) of whom 210 (38.7%) had a CUP diagnosis confirmed. Within the cohort, 347 patients (64.0%) had a registration in CR matching with the NPR registration. Exposure to diagnostic procedures included biopsy (n = 439, 81.0%) and image modalities (n = 532, 98.2%). Survival was poor with 67 (12.4%) individuals alive after 4 years.The validity of a CUP diagnosis in NPR was low when using data from CR as reference. More than half the suspected CUP patients had a previous cancer diagnosis with CUP being the most frequent. Patients were diagnosed in compliance with guidelines indicating high external validity, but less than 1 quarter had their primary identified and the 1-year survival was approximately 20%. Research is needed to develop efficacious methods for primary detection.

Longitudinal Risk of Adverse Events in Patients With Acute Kidney Injury After Percutaneous Coronary Intervention: Insights From the National Cardiovascular Data Registry.

Acute kidney injury (AKI) remains a common complication after percutaneous coronary intervention (PCI) and is associated with adverse in-hospital patient outcomes. The incidence of adverse events after hospital discharge in patients having post-PCI AKI is poorly defined, and the relationship between AKI and outcomes after hospital discharge remains understudied.

Risk of Pertussis in Relation to Degree of Prematurity in Children Less Than 2 Years of Age.

A few previous studies reported increased risk of pertussis in children with birth weight less than 2500 g. The risk of pertussis by degree of prematurity has not been determined in a cohort study. The vaccine effectiveness (VE) against reported pertussis in preterm infants is unknown.

Comparing First- and Second-year Palivizumab Prophylaxis in Patients With Hemodynamically Significant Congenital Heart Disease in the CARESS Database (2005-2015).

Respiratory syncytial virus hospitalization (RSVH) rates in children <2 years of age with hemodynamically significant congenital heart disease (HSCHD) are 2- to 4-fold higher compared with healthy term infants. Pediatric recommendations differ as to whether palivizumab is beneficial beyond 1 year of age. The objective of this study was to determine whether differences exist in respiratory-related illness hospitalization (RIH) and RSVH in HSCHD infants receiving palivizumab during the first year versus second year of life in the Canadian Registry of Palivizumab.

Matched Comparison of Self-Expanding Transcatheter Heart Valves for the Treatment of Failed Aortic Surgical Bioprosthesis: Insights From the Valve-in-Valve International Data Registry (VIVID).

Transcatheter valve-in-valve implantation is an established therapy for high-risk patients with failed surgical aortic bioprosthesis. There are limited data comparing outcomes of valve-in-valve implantation using different transcatheter heart valves (THV).

Voluntarily Reported Immunization Registry Data: Reliability and Feasibility to Predict Immunization Rates, San Diego, California, 2013.

Accurate data on immunization coverage levels are essential to public health program planning. Reliability of coverage estimates derived from immunization information systems (IISs) in states where immunization reporting by medical providers is not mandated by the state may be compromised by low rates of participation. To overcome this problem, data on coverage rates are often acquired through random-digit-dial telephone surveys, which require substantial time and resources. This project tested both the reliability of voluntarily reported IIS data and the feasibility of using these data to estimate regional immunization rates.

Is admittance to specialised palliative care among cancer patients related to sex, age and cancer diagnosis? A nation-wide study from the Danish Palliative Care Database (DPD).

Specialised palliative care (SPC) takes place in specialised services for patients with complex symptoms and problems. Little is known about what determines the admission of patients to SPC and whether there are differences in relation to institution type. The aims of the study were to investigate whether cancer patients' admittance to SPC in Denmark varied in relation to sex, age and diagnosis, and whether the patterns differed by type of institution (hospital-based palliative care team/unit, hospice, or both).

Current Practices in the Timing of Stage 2 Palliation.

Mortality through single-ventricle palliation remains high and the effect of the timing of stage 2 palliation (S2P) is not well understood. We investigated current practice patterns in the timing of S2P across two professional societies and compared them to actual practice patterns from two databases of patients who underwent S2P.

Identifying multiple myeloma patients using data from the French health insurance databases: Validation using a cancer registry.

This study aimed to assess the performance of several algorithms based on hospital diagnoses and the long-term diseases scheme to identify multiple myeloma patients.Potential multiple myeloma patients in 2010 to 2013 were identified using the presence of hospital records with at least 1 main diagnosis code for multiple myeloma (ICD-10 "C90"). Alternative algorithms also considered related and associated diagnoses, combination with long-term conditions, or at least 2 diagnoses. Incident patients were those with no previous "C90" codes in the past 24 or 12 months. The sensitivity, specificity, and positive and negative predictive values (PPVs and NPVs) were computed, using a French cancer registry for the corresponding area and period as the criterion standard.Long-term conditions data extracted concerned 11,559 patients (21,846 for hospital data). The registry contained 125 cases of multiple myeloma. Sensitivity was 70% when using only main hospital diagnoses (specificity 100%, PPV 79%), 76% when also considering related diagnoses (specificity 100%, PPV 74%), and 90% with associated diagnoses included (100% specificity, 64% PPV).In relation with their good performance, selected algorithms can be used to study the benefit and risk of drugs in treated multiple myeloma patients.

Transcatheter Aortic Valve Implantation in Patients With Advanced Chronic Kidney Disease.

Advanced chronic kidney disease (CKD) is associated with poor outcomes in patients who underwent surgical aortic valve replacement, whereas its prognostic role in transcatheter aortic valve implantation (TAVI) remains unclear. This study aimed to investigate outcomes in patients with advanced CKD who underwent TAVI. A total of 1,904 consecutive patients who underwent balloon-expandable TAVI in 33 centers between 2007 and 2012 were enrolled in the Italian Transcatheter Balloon-Expandable Valve Implantation Registry. Advanced CKD was defined according to the estimated glomerular filtration rate: 15 to 29 ml/min/1.73 m(2) stage 4 (S4), <15 ml/min/1.73 m(2) stage 5 (S5). Edwards Sapien or Sapien-XT prosthesis were used. The primary end point was all-cause mortality during follow-up. Secondary end points were major adverse cardiac events at 30 days and at follow-up, defined with Valve Academic Research Consortium 2 criteria. A total of 421 patients were staged S5 (n = 74) or S4 (n = 347). S5 patients were younger and had more frequently porcelain aorta and a lower incidence of previous stroke. Periprocedural and 30-day outcomes were similar in S5 and S4 patients. During 670 (±466) days of follow-up, S5 patients had higher mortality rates (69% vs 39%, p <0.01) and cardiac death (19% vs 9%, p = 0.02) compared with S4 patients. Male gender (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.2 to 2.2), left ventricular ejection fraction <30% (HR 2.3, 95% CI 1.3 to 4), atrial fibrillation (HR 1.4, 95% CI 1.0 to 1.9), and S5 CKD (HR 1.5, 95% CI 1.0 to 2.1) were independent predictors of death. In conclusion, TAVI in predialytic or dialytic patients (i.e., S5) is independently associated with poor outcomes with more than double risk of death compared with patients with S4 renal function. Conversely, in severe CKD (i.e., S4) a rigorous risk stratification is required to avoid the risk of futility risk.

Comparative Efficacy of Coronary Revascularization Procedures for Multivessel Coronary Artery Disease in Patients With Chronic Kidney Disease.

Patients with chronic kidney disease (CKD) are at increased risk of cardiovascular disease and death, yet little data exist regarding the comparative efficacy of coronary revascularization procedures in CKD patients with multivessel disease. We created a cohort of 4,687 adults who underwent cardiac catheterization, had a serum creatinine value measured within 30 days, and had more than one vessel with ≥50% stenosis. We used Cox proportional hazard regression modeling weighted by the inverse probability of treatment to examine the association between 4 treatment strategies (medical management, percutaneous coronary intervention [PCI] with bare metal stent, PCI with drug-eluting stent, and coronary artery bypass grafting [CABG]) and mortality among patients across categories of estimated glomerular filtration rate; secondary outcome was a composite of mortality, myocardial infarction, or revascularization. Compared with medical management, CABG was associated with a reduced risk of death for patients of any nondialysis CKD severity (hazard ratio [HR] range 0.43 to 0.59). There were no significant mortality differences between CABG and PCI, except a decreased death risk in CABG-treated CKD patients (HR range 0.54 to 0.55). Compared with medical management and PCI, CABG was associated with a lower risk of death, myocardial infarction, or revascularization in nondialysis CKD patients (HR range 0.41 to 0.64). There were similar associations between decreased estimated glomerular filtration rate and increased mortality across all multivessel coronary artery disease patient treatment groups. When accounting for treatment propensity, surgical revascularization was associated with improved outcomes in patients of all CKD severities. A prospective randomized trial in CKD patients is required to confirm our findings.

Pigmentation phenotype, photosensitivity and skin neoplasms in patients with myotonic dystrophy.

Recent studies have suggested a possible excess risk of skin neoplasms in patients with myotonic dystrophy (DM). Risk factors related to this observation have not been defined.

Stroke recurrence in patients with atrial fibrillation: concomitant carotid artery stenosis doubles the risk.

Atrial fibrillation (AF) and significant carotid artery stenosis (CAS) often coexist in patients with acute stroke but whether CAS affects the stroke recurrence rate in anticoagulated AF patients is largely unknown. The effect of concomitant CAS on both short- and long-term prognosis after stroke in patients with AF was evaluated.

Creutzfeldt-Jakob disease surveillance in Australia: update to December 2015.

Nation-wide surveillance of human transmissible spongiform encephalopathies (also known as prion diseases), the most common being Creutzfeldt-Jakob disease, is performed by the Australian National Creutzfeldt-Jakob Disease Registry, based at the University of Melbourne. Prospective surveillance has been undertaken since 1993 and over this dynamic period in transmissible spongiform encephalopathy research and understanding, the unit has evolved and adapted to changes in surveillance practices and requirements concomitant with the delineation of new disease subtypes, improvements in diagnostic capabilities and the overall heightened awareness of prion diseases in the health care setting. In 2015, routine national surveillance continued and this brief report provides an update of the cumulative surveillance data collected by the Australian National Creutzfeldt-Jakob Disease Registry prospectively from 1993 to December 2015, and retrospectively to 1970.
