Introduction: This systematic literature review (SLR) assessed incidence/prevalence of cryptoglandular fistulas (CCF) and outcomes associated with local surgical and intersphincteric ligation procedures for CCFs.
Methods: Two trained reviewers searched PubMed and Embase for observational studies evaluating the incidence/prevalence of cryptoglandular fistula and clinical outcomes of treatments for CCF after local surgical and intersphincteric ligation procedures for CCF.
Results: In total 148 studies met a priori eligibility criteria for all cryptoglandular fistulas and all intervention types.
Background: Enterocutaneous fistulas (ECF) are rare sequelae of Crohn's disease (CD) that occur either postoperatively or spontaneously. ECFs are associated with high morbidity and mortality. This systematic literature review assesses the disease burden of CD-related ECF and identifies knowledge gaps around incidence/prevalence, treatment patterns, clinical outcomes, healthcare resource utilization (HCRU), and patient-reported outcomes (PROs).

Background: Selection of appropriate trial endpoints and outcome measures is particularly important in rare disease and rapidly progressing disease such as amyotrophic lateral sclerosis (ALS) where the challenges to conducting clinical trials, are substantial: patient and disease heterogeneity, limited understanding of exact disease pathophysiology, and lack of robust and available biomarkers. To address these challenges in ALS, the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised version (ALSFRS-R) was developed and has become a key primary endpoint in ALS clinical trials to assess functional disability and disease progression, often replacing survival as a primary outcome. However, increased understanding of the ALS disease journey and improvements in assistive technology for ALS patients have exposed issues with the ALSFRS-R, including non-linearity, multidimensionality and floor and ceiling effects that could challenge its continued utility as a primary outcome measure in ALS clinical trials.

In a rare disease like amyotrophic lateral sclerosis (ALS), studies of disease natural history critically depend on collaboration between clinical centers, regions, and countries to enable creation of platforms to allow patients, caregivers, clinicians, and researchers to come together and more fully understand the condition. Rare disease registries and collaborative platforms such as those developed in ALS collect real-world data (RWD) in standardized formats, including clinical and biological specimen data used to evaluate risk factors and natural history of disease, treatment patterns and clinical (ClinROs) and patient- reported outcomes (PROs) and validate novel endpoints.

Objective: To investigate subtype concordance among siblings with SMA.
Background: Acute coronary syndrome patients receiving dual antiplatelet therapy who need emergent or urgent cardiac surgery are at high risk of major bleeding, which can impair postoperative outcomes. CytoSorb, a blood purification technology based on adsorbent polymer, has been demonstrated to remove ticagrelor from blood during on-pump cardiac surgery.
Objective: The aim of this study was to evaluate the cost utility of intraoperative removal of ticagrelor using CytoSorb versus usual care among patients requiring emergent or urgent cardiac surgery in the UK.
Background: The Cure SMA database is one of the largest patient reported databases for people affected with SMA.
Objective: The purpose of this study was to examine a subset of affected SMA persons with types I, II, and III from a patient reported database.
Methods: Individuals with SMA were selected from the database using a date of first contact to Cure SMA between 2010 and 2016.
Background: Spinal muscular atrophy (SMA) is a progressive, devastating disease and a leading inherited cause of infant mortality. The limited population-based literature is confined to small regional studies. Estimates of prevalence are needed to characterize the burden of SMA and to understand trends in prevalence by disease type as new treatments become available.

Novel associations controlling for a false discovery rate of 5% included the association of the variant encoding p.
View Article and Find Full Text PDFSpinal muscular atrophy linked to chromosome 5q (SMA) is a recessive, progressive, neuromuscular disorder caused by bi-allelic mutations in the SMN1 gene, resulting in motor neuron degeneration and variable presentation in relation to onset and severity. A prevalence of approximately 1-2 per 100,000 persons and incidence around 1 in 10,000 live births have been estimated with SMA type I accounting for around 60% of all cases. Since SMA is a relatively rare condition, studies of its prevalence and incidence are challenging.
View Article and Find Full Text PDFIn spinal muscular atrophy (SMA), degeneration of motor neurons causes progressive muscular weakness, which is caused by homozygous deletion of the SMN1 gene. Available epidemiological data on SMA are scarce, often outdated, and limited to relatively small regions or populations. Combining data from different sources including genetic laboratories and patient registries may provide better insight of the disease epidemiology.

Internet-based studies provide new opportunities to study patient-reported outcomes and can be efficiently implemented and scaled. If a traditional cohort study was linked to an Internet-based study, both studies could benefit from added synergy.

Objective: Our aim was to study the feasibility of collecting biospecimens from CCFA Partners, an Internet-based inflammatory bowel disease (IBD) cohort.
Purpose: Considerations for using administrative claims data in research have not been well-described. To increase awareness of how enrollment factors and insurance benefit use may contribute to prevalence estimates, we evaluated how differences in operational definitions of the cohort impact observed estimates.
Methods: We conducted a cross-sectional study estimating the prevalence of five gastrointestinal conditions using MarketScan claims data for 73.
Background: Little is known about beliefs, understanding, and perceptions of biobanking among patients with inflammatory bowel diseases. We aimed to further understand perceptions of biobanking in the inflammatory bowel disease community.
Methods: Subjects were recruited to participate in a 1:1 telephone interview on their perceptions of the risks and benefits of contributing specimens for research.
There is an urgent need to identify lifestyle activities that reduce functional decline and dementia associated with population aging. The goals of this article are to review critically the evidence on the benefits associated with formal volunteering among older adults, propose a theoretical model of how volunteering may reduce functional limitations and dementia risk, and offer recommendations for future research. Database searches identified 113 papers on volunteering benefits in older adults, of which 73 were included.

Background & Aims: Narcotic analgesics are not recommended for long-term management of pain for patients with inflammatory bowel disease (IBD), particularly pediatric patients. We compared chronic use of narcotics among children with IBD and the general population and investigated factors associated with narcotic use in the pediatric IBD population.
Methods: This cross-sectional study included children (younger than 18 years old) with continuous enrollment in a large administrative claims database from 2010 through 2011 (n = 4,911,286).
Background: As traditional methods have become increasingly difficult, the Internet offers a mechanism for conducting survey research quickly and efficiently. However, the validity of this research depends on the ability of respondents to accurately report health status. We used a large Internet-based inflammatory bowel disease (IBD) cohort to validate self-reported IBD against physician reports.

The authors aimed to describe the prevalence and predictors of non-IBD medication use and to compare drug use among individuals with and without IBD.
Methods: This cross-sectional study included members of health plans included in the Thomson Reuters MarketScan databases with continuous enrollment during 2009 and 2010.
Purpose Of The Study: This study explores (a) whether retirees' formal volunteer experiences represent an extension of their career in the paid workforce; and (b) how this integration of life roles affects career self-concept, as interpreted through Donald Super's life-span, life-space theory of career development.
Design And Methods: A survey was conducted involving a Canadian sample of 214 individuals aged 55-75 years to examine retirees' volunteer activities and their sense of self.
Results: The results demonstrate the need to further develop Super's theory with the addition of a new developmental stage, which I am labeling "Redirection" to better reflect postretirement experiences.
