Who Are the Remaining Uninsured and Why Haven't They Signed Up for Coverage? Findings from the Commonwealth Fund Affordable Care Act Tracking Survey, FebruaryApril 2016

The number of uninsured people in the United States has declined by an estimated 20 million since the Affordable Care Act went into effect in 2010. Yet, an estimated 24 million people still lack health insurance. Goal: To examine the characteristics of the remaining uninsured adults and their reasons for not enrolling in marketplace plans or Medicaid. Methods: Analysis of the Commonwealth Fund ACA Tracking Survey, February–April 2016. Key findings and conclusions: There have been notable shifts in the demographic composition of the uninsured since the law's major coverage expansions went into effect in 2014. Latinos have become a growing share of the uninsured, rising from 29 percent in 2013 to 40 percent in 2016. Whites have become a declining share, falling from half the uninsured in 2013 to 41 percent in 2016. The uninsured are very poor: 39 percent of uninsured adults have incomes below the federal poverty level, twice the rate of their overall representation in the adult population. Of uninsured adults who are aware of the marketplaces or who have tried to enroll for coverage, the majority point to affordability concerns as a reason for not signing up

Following the ACA Repeal-and-Replace Effort, Where Does the U.S. Stand on Insurance Coverage? Findings from the Commonwealth Fund Affordable Care Act Tracking Survey, MarchJune 2017

Issue: After Congress's failure to repeal and replace the Affordable Care Act, some policy leaders are calling for bipartisan approaches to address weaknesses in the law's coverage expansions. To do this, policymakers will need data about trends in insurance coverage, reasons why people remain uninsured, and consumer perceptions of affordability.Goal: To examine U.S. trends in insurance coverage and the demographics of the remaining uninsured population, as well as affordability and satisfaction among adults with marketplace and Medicaid coverage.Methods: Analysis of the Commonwealth Fund Affordable Care Act Tracking Survey, March–June 2017.Findings and Conclusions: The uninsured rate among 19-to-64-year-old adults was 14 percent in 2017, or an estimated 27 million people, statistically unchanged from one year earlier. Uninsured rates ticked up significantly in three subgroups: 35-to-49-year-olds, adults with incomes of 400 percent of poverty or more (about $48,000 for an individual), and adults living in states that had not expanded Medicaid. Half of uninsured adults, or an estimated 13 million, are likely eligible for marketplace subsidies or the Medicaid expansion in their state. Four of 10 uninsured adults are unaware of the marketplaces. Adults in marketplace plans with incomes below 250 percent of poverty are much more likely to view their premiums as easy to afford compared with people with higher incomes. Policies to improve coverage include a federal commitment to supporting the marketplaces and the 2018 open enrollment period, expansion of Medicaid in 19 remaining states, and enhanced subsidies for people with incomes of 250 percent of poverty or more

How the Affordable Care Act Has Helped Women Gain Insurance and Improved Their Ability to Get Health Care

Issue: Prior to the Affordable Care Act (ACA), one-third of women who tried to buy a health plan on their own were either turned down, charged a higher premium because of their health, or had specific health problems excluded from their plans. Beginning in 2010, ACA consumer protections, particularly coverage for preventive care screenings with no cost-sharing and a ban on plan benefit limits, improved the quality of health insurance for women. In 2014, the law's major insurance reforms helped millions of women who did not have employer insurance to gain coverage through the ACA's marketplaces or through Medicaid.Goals: To examine the effects of ACA health reforms on women's coverage and access to care.Method: Analysis of the Commonwealth Fund Biennial Health Insurance Surveys, 2001–2016.Findings and Conclusions: Women ages 19 to 64 who shopped for new coverage on their own found it significantly easier to find affordable plans in 2016 compared to 2010. The percentage of women who reported delaying or skipping needed care because of costs fell to an all-time low. Insured women were more likely than uninsured women to receive preventive screenings, including Pap tests and mammograms

Americans' Views on Health Insurance at the End of a Turbulent Year

The Affordable Care Act's 2018 open enrollment period came at the end of a turbulent year in health care. The Trump administration took several steps to weaken the ACA's insurance marketplaces. Meanwhile, congressional Republicans engaged in a nine-month effort to repeal and replace the law's coverage expansions and roll back Medicaid. Nevertheless, 11.8 million people had selected plans through the marketplaces by the end of January, about 3.7 percent fewer than the prior year. There was an overall increase in enrollment this year in states that run their own marketplaces and a decrease in those states that rely on the federal marketplace.To gauge the perspectives of Americans on the marketplaces, Medicaid, and other health insurance issues, the Commonwealth Fund Affordable Care Act Tracking Survey interviewed a random, nationally representative sample of 2,410 adults ages 19 to 64 between November 2 and December 27, 2017, including 541 people who have marketplace or Medicaid coverage.The findings are compared to prior ACA tracking surveys, the most recent of which was fielded between March and June 2017. The survey research firm SSRS conducted the survey, which has an overall margin of error is +/– 2.7 percentage points at the 95 percent confidence level

How Medicaid Enrollees Fare Compared with Privately Insured and Uninsured Adults: Findings from the Commonwealth Fund Biennial Health Insurance Survey, 2016

Issue: The number of Americans insured by Medicaid has climbed to more than 70 million, with an estimated 12 million gaining coverage under the Affordable Care Act's Medicaid expansion. Still, some policymakers have questioned whether Medicaid coverage actually improves access to care, quality of care, or financial protection. Goals: To compare the experiences of working-age adults who were either: covered all year by private employer or individual insurance; covered by Medicaid for the full year; or uninsured for some time during the year. Method: Analysis of the Commonwealth Fund Biennial Health Insurance Survey, 2016. Findings and Conclusions: The level of access to health care that Medicaid coverage provides is comparable to that afforded by private insurance. Adults with Medicaid coverage reported better care experiences than those who had been uninsured during the year. Medicaid enrollees have fewer problems paying medical bills than either the privately insured or the uninsured

Cell-Cycle Protein Expression in a Population-Based Study of Ovarian and Endometrial Cancers

Aberrant expression of cyclin-dependent kinase (CDK) inhibitors is implicated in the carcinogenesis of many cancers, including ovarian and endometrial cancers. We examined associations between CDK inhibitor expression, cancer risk factors, tumor characteristics, and survival outcomes among ovarian and endometrial cancer patients enrolled in a population-based case control study. Expression (negative vs. positive) of three CDK inhibitors (p16, p21, p27) and ki67 was examined with immunohistochemical staining of tissue microarrays. Logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between biomarkers, risk factors, and tumor characteristics. Survival outcomes were available for ovarian cancer patients and examined using Kaplan-Meier plots and Cox proportional hazards regression. Among ovarian cancer patients (n=175), positive p21 expression was associated with endometrioid tumors (OR=12.22, 95% CI=1.45-102.78) and higher overall survival (log-rank p=0.002). In Cox models adjusted for stage, grade, and histology, the association between p21 expression and overall survival was borderline significant (hazard ratio=0.65, 95% CI=0.42-1.05). Among endometrial cancer patients (n=289), positive p21 expression was inversely associated with age (OR ≥ 65 years of age=0.25, 95% CI=0.07-0.84) and current smoking status (OR: 0.33, 95% CI 0.15, 0.72) compared to negative expression. Our study showed heterogeneity in expression of cell-cycle proteins associated with risk factors and tumor characteristics of gynecologic cancers. Future studies to assess these markers of etiological classification and behavior may be warranted

Elastin is Localised to the Interfascicular Matrix of Energy Storing Tendons and Becomes Increasingly Disorganised With Ageing

Tendon is composed of fascicles bound together by the interfascicular matrix (IFM). Energy storing tendons are more elastic and extensible than positional tendons; behaviour provided by specialisation of the IFM to enable repeated interfascicular sliding and recoil. With ageing, the IFM becomes stiffer and less fatigue resistant, potentially explaining why older tendons become more injury-prone. Recent data indicates enrichment of elastin within the IFM, but this has yet to be quantified. We hypothesised that elastin is more prevalent in energy storing than positional tendons, and is mainly localised to the IFM. Further, we hypothesised that elastin becomes disorganised and fragmented, and decreases in amount with ageing, especially in energy storing tendons. Biochemical analyses and immunohistochemical techniques were used to determine elastin content and organisation, in young and old equine energy storing and positional tendons. Supporting the hypothesis, elastin localises to the IFM of energy storing tendons, reducing in quantity and becoming more disorganised with ageing. These changes may contribute to the increased injury risk in aged energy storing tendons. Full understanding of the processes leading to loss of elastin and its disorganisation with ageing may aid in the development of treatments to prevent age related tendinopathy

Behavioural ‘nudging’ interventions to reduce low-value care for low back pain in the emergency department (NUDGED): protocol for a 2×2 factorial, before-after, cluster randomised trial

Introduction:Opioids and imaging are considered low-value care for most people with low back pain. Yet around one in three people presenting to the emergency department (ED) will receive imaging, and two in three will receive an opioid. NUDG-ED aims to determine the effectiveness of two different behavioural ‘nudge’ interventions on low-value care for ED patients with low back pain. Methods and analysis:NUDG-ED is a 2×2 factorial, open-label, before-after, cluster randomised controlled trial. The trial includes 8 ED sites in Sydney, Australia. Participants will be ED clinicians who manage back pain, and patients who are 18 years or over presenting to ED with musculoskeletal back pain. EDs will be randomly assigned to receive (i) patient nudges, (ii) clinician nudges, (iii) both interventions or (iv) no nudge control. The primary outcome will be the proportion of encounters in ED for musculoskeletal back pain where a person received a non-indicated lumbar imaging test, an opioid at discharge or both. We will require 2416 encounters over a 9-month study period (3-month before period and 6-month after period) to detect an absolute difference of 10% in use of low-value care due to either nudge, with 80% power, alpha set at 0.05 and assuming an intra-class correlation coefficient of 0.10, and an intraperiod correlation of 0.09. Patient-reported outcome measures will be collected in a subsample of patients (n≥456) 1 week after their initial ED visit. To estimate effects, we will use a multilevel regression model, with a random effect for cluster and patient, a fixed effect indicating the group assignment of each cluster and a fixed effect of time. Ethics and dissemination:This study has ethical approval from Southwestern Sydney Local Health District Human Research Ethics Committee (2023/ETH00472). We will disseminate the results of this trial via media, presenting at conferences and scientific publications.</p

Dynamic culturing of cartilage tissue: the significance of hydrostatic pressure

Human articular cartilage functions under a wide range of mechanical loads in synovial joints, where hydrostatic pressure (HP) is the prevalent actuating force. We hypothesized that the formation of engineered cartilage can be augmented by applying such physiologic stimuli to chondrogenic cells or stem cells, cultured in hydrogels, using custom-designed HP bioreactors. To test this hypothesis, we investigated the effects of distinct HP regimens on cartilage formation in vitro by either human nasal chondrocytes (HNCs) or human adipose stem cells (hASCs) encapsulated in gellan gum (GG) hydrogels. To this end, we varied the frequency of low HP, by applying pulsatile hydrostatic pressure or a steady hydrostatic pressure load to HNC-GG constructs over a period of 3 weeks, and evaluated their effects on cartilage tissue-engineering outcomes. HNCs (10 · 106 cells/ mL) were encapsulated in GG hydrogels (1.5%) and cultured in a chondrogenic medium under three regimens for 3 weeks: (1) 0.4MPa Pulsatile HP; (2) 0.4MPa Steady HP; and (3) Static. Subsequently, we applied the pulsatile regimen to hASC-GG constructs and varied the amplitude of loading, by generating both low (0.4 MPa) and physiologic (5 MPa) HP levels. hASCs (10x106 cells/mL) were encapsulated in GG hydrogels (1.5%) and cultured in a chondrogenic medium under three regimens for 4 weeks: (1) 0.4MPa Pulsatile HP; (2) 5MPa Pulsatile HP; and (3) Static. In the HNC study, the best tissue development was achieved by the pulsatile HP regimen, whereas in the hASC study, greater chondrogenic differentiation and matrix deposition were obtained for physiologic loading, as evidenced by gene expression of aggrecan, collagen type II, and sox-9; metachromatic staining of cartilage extracellular matrix; and immunolocalization of collagens. We thus propose that both HNCs and hASCs detect and respond to physical forces, thus resembling joint loading, by enhancing cartilage tissue development in a frequency- and amplitude-dependant manner.Fundação para a Ciência e a Tecnologia (FCT) - SFRH/BD/42316/200

Elevated urinary excretion of free pyridinoline in Friesian horses suggests a breed-specific increase in collagen degradation

Background: Friesian horses are known for their high inbreeding rate resulting in several genetic diseases such as hydrocephaly and dwarfism. This last decade, several studies focused on two other presumed hereditary traits in Friesian horses: megaoesophagus and aortic rupture. The pathogenesis of these diseases remains obscure but an important role of collagen has been hypothesized. The purpose of this study was to examine possible breed-related differences in collagen catabolism. Urinary specimens from Friesian (n = 17, median age 10 years old) and Warmblood horses (n = 17, median age 10 years old) were assessed for mature collagen cross-links, i.e. pyridinoline (PYD) (=hydroxylysylpyridinoline/HP) and deoxypyridinoline (DPD) (lysylpyridinoline /LP). Solid-phase extraction was performed, followed by reversed-phase ion-paired liquid chromatography prior to tandem mass spectrometry (MS/MS) detection. Results: Mean urinary concentrations of free PYD, expressed as fPYD/creatinine ratio, were significantly higher in Friesian horses compared to Warmblood horses (28.5 ± 5.2 versus 22.2 ± 9.6 nmol/mmol, p = 0.02) while mean fDPD/creatinine ratios were similar in both horse breeds (3.0 ± 0.7 versus 4.6 ± 3.7 nmol/mmol, p = 0.09). Conclusions: Since DPD is considered a specific bone degradation marker and PYD is more widely distributed in connective tissues, the significant elevation in the mean PYD/DPD ratio in Friesian versus Warmblood horses (9.6 ± 1.6 versus 5.7 ± 1.8, p < 0.0001) suggests a soft tissue origin for the increased fPYD levels. Considering that a previous study found no differences in total collagen content between Friesian and Warmblood horses for tendon and aortic tissue, this indicates a higher rate of collagen degradation. The latter might, at least in part, explain the predisposition of Friesians to connective tissue disorders
