BackgroundWhile the United States has the largest number of children with type 1 diabetes mellitus, less is known regarding adult-onset disease. The present study utilizes nationwide data to compare the incidence of type 1 diabetes in youth (0–19 years) to that of adults (20–64 years).MethodsIn this longitudinal study, the Clinformatics® Data Mart Database was used, which contains information from 61 million commercially insured Americans (years 2001–2015). Incidence rates and exact Poisson 95% confidence intervals were calculated by age group, sex, census division, and year of diagnosis. Changes in rates over time were assessed by negative binomial regression.ResultsOverall, there were 32,476 individuals who developed type 1 diabetes in the cohort. The incidence rate was greatest in youth aged 10–14 years (45.5 cases/100,000 person-years); however, because adulthood spans over a longer period than childhood, there was a greater number of new cases in adults than in youth (n = 19,174 adults; n = 13,302 youth). Predominance in males was evident by age 10 and persisted throughout adulthood. The male to female incidence rate ratio was 1.32 (95% CI 1.30–1.35). The incidence rate of type 1 diabetes in youth increased by 1.9% annually from 2001 to 2015 (95% CI 1.1–2.7%; P < 0.001), but there was variation across regions. The greatest increases were in the East South Central (3.8%/year; 95% CI 2.0–5.6%; P < 0.001) and Mountain divisions (3.1%/year; 95% CI 1.6–4.6%; P < 0.001). There were also increases in the East North Central (2.7%/year; P = 0.010), South Atlantic (2.4%/year; P < 0.001), and West North Central divisions (2.4%/year; P < 0.001). In adults, however, the incidence decreased from 2001 to 2015 (−1.3%/year; 95% CI −2.3% to −0.4%; P = 0.007). Greater percentages of cases were diagnosed in January, July, and August for both youth and adults. The number of new cases of type 1 diabetes (ages 0–64 years) in the United States is estimated at 64,000 annually (27,000 cases in youth and 37,000 cases in adults).ConclusionsThere are more new cases of type 1 diabetes occurring annually in the United States than previously recognized. The increase in incidence rates in youth, but not adults, suggests that the precipitating factors of youth-onset disease may differ from those of adult-onset disease.Electronic supplementary materialThe online version of this article (10.1186/s12916-017-0958-6) contains supplementary material, which is available to authorized users.

Women surgeons have a small but growing presence on surgical editorial boards, and gender-based qualification differences are likely attributable to practice length. Men's longer tenure on editorial boards may drive some of the observed disparity by limiting new appointment opportunities. Strategies such as imposing term limits or instituting merit-based performance reviews may help editorial boards capture the field's changing demographics.

PurposeThis study examined the effectiveness, feasibility, and satisfaction with implementation of the FOCUS program in two US Cancer Support Community affiliates in Ohio and California as well as the cost to deliver the program. FOCUS is an evidence-based psychoeducational intervention for dyads (cancer patients and caregivers).MethodsA pre-post-intervention design was employed. Eleven, five-session Focus programs were delivered by licensed professionals in a small group format (three–four dyads/group) to 36 patient-caregiver dyads. An Implementation Training Manual, a FOCUS Intervention Protocol Manual, and weekly conference calls were used to foster implementation. Participants completed questionnaires prior to and following completion of each five-session FOCUS program to measure primary (emotional distress, quality of life) and secondary outcomes (benefits of illness, self-efficacy, and dyadic communication). Enrollment and retention rates and fidelity to FOCUS were used to measure feasibility. Cost estimates were based on time and median hourly wages. Repeated analysis of variance was used to analyze the effect of FOCUS on outcomes for dyads. Descriptive statistics were used to examine feasibility, satisfaction, and cost estimates.ResultsFOCUS had positive effects on QOL (p = .014), emotional (p = .012), and functional (p = .049) well-being, emotional distress (p = .002), benefits of illness (p = .013), and self-efficacy (p = .001). Intervention fidelity was 85% with enrollment and retention rates of 71.4 and 90%, respectively. Participants were highly satisfied. Cost for oversight and delivery of the five-session FOCUS program was $168.00 per dyad.ConclusionsFOCUS is an economic and effective intervention to decrease distress and improve the quality of life for dyads.

BackgroundRheumatic Heart Disease (RHD), a chronic acquired heart disorder results from Acute Rheumatic Fever. It is a major public health concern in developing countries. In RHD, mostly the valves get affected. The present study investigated whether extracellular matrix remodelling in rheumatic valve leads to altered levels of collagen metabolism markers and if such markers can be clinically used to diagnose or monitor disease progression.MethodologyThis is a case control study comprising 118 subjects. It included 77 cases and 41 healthy controls. Cases were classified into two groups- Mitral Stenosis (MS) and Mitral Regurgitation (MR). Carboxy-terminal propeptide of type I procollagen (PICP), amino-terminal propeptide of type III procollagen (PIIINP), total Matrix Metalloproteinase-1(MMP-1) and Tissue Inhibitor of Metalloproteinase-1 (TIMP-1) were assessed. Histopathology studies were performed on excised mitral valve leaflets. A p value <0.05 was considered statistically significant.ResultsPlasma PICP and PIIINP concentrations increased significantly (p<0.01) in MS and MR subjects compared to controls but decreased gradually over a one year period post mitral valve replacement (p<0.05). In MS, PICP level and MMP-1/TIMP-1 ratio strongly correlated with mitral valve area (r = −0.40; r = 0.49 respectively) and pulmonary artery systolic pressure (r = 0.49; r = −0.49 respectively); while in MR they correlated with left ventricular internal diastolic (r = 0.68; r = −0.48 respectively) and systolic diameters (r = 0.65; r = −0.55 respectively). Receiver operating characteristic curve analysis established PICP as a better marker (AUC = 0.95; 95% CI = 0.91−0.99; p<0.0001). A cut-off >459 ng/mL for PICP provided 91% sensitivity, 90% specificity and a likelihood ratio of 9 in diagnosing RHD. Histopathology analysis revealed inflammation, scarring, neovascularisation and extensive leaflet fibrosis in diseased mitral valve.ConclusionsLevels of collagen metabolism markers correlated with echocardiographic parameters for RHD diagnosis.

The use of a reliable, valid, and sensitive criterion-standard QLQ-CIPN20 variant in clinical practice settings could improve function, quality of life, and CIPN symptom control by facilitating patient reporting and thereby clinician awareness of this underrecognized consequence of cancer therapy.
