Patient Accessibility to Eye Care in the United States

The United States (US) federal government uses health provider shortage areas (HPSAs) to define patient accessibility to primary care physicians. It is unclear whether HPSAs can be applied to eye care providers (ECPs). Our study determined the applicability of federal HPSA designations to ECP availability in the US. Cross-sectional study. US general population and ophthalmologists/optometrists in the Medicare database. The primary care HPSA score, visual impairment prevalence, and ECP location were determined for each census tract or county using data from the US Department of Health and Human Services, the Centers for Disease Control and Prevention, and Centers for Medicare and Medicaid Services. Association of HPSA with vision loss and ECP density was examined. The 2-step floating catchment area approach was used to newly define eye care shortage areas (patient accessibility score [PAS], higher being worse accessibility) for every county in the US, by weighting the 2-step FCA scores by prevalence of vision loss and ECP density. Multivariable logistic regression was used to identify sociodemographic variables associated with areas of ECP shortage. Among 72 735 census tracts included, statistically significant but weak correlations of HPSA scorewith visual impairment (VI) (r= 0.38; P < 0.0001) and ECP density per county population (r= -0.18; P < 0.0001) werefound. Only 54.0% of census tracts with < 25th percentile ECP density per county were HPSAs (P < 0.0001). Of census tracts > than 75th percentile for VI only 58.0% were HPSAs (P < 0.0001). Multivariable regression found a higher odds of ECP PAS ≥ 75th percentile (worseaccessibility) in rural counties (adjusted odds ratio [aOR], 2.47; 95% confidence interval [CI], 1.93-3.67; P< 0.001) and counties with a greater prevalence of residents with less than a high school education (aOR, 1.21; 95% CI, 1.19-1.25; P < 0.001), residents ≥ 65 years of age (aOR, 1.10; 95% CI, 1.07-1.13; P < 0.001), and uninsured residents (aOR, 1.04; 95% CI, 1.01-1.06; P < 0.001). Counties with a greater proportion of men (aOR, 0.93; 95% CI, 0.89-0.967; P < 0.001) or White residents (aOR, 0.99; 95% CI, 0.98-0.99) had a lower odds of ECP PAS ≥ 75th percentile. Current HPSAs only weakly correlate with ECP supply. We propose a new approach to identify counties with high need but limited access to eye care.

Using patient-reported outcome measures to assess psychological well-being in a non-representative US general population during the COVID-19 pandemic

PurposeThe impact of the COVID-19 pandemic on psychological well-being will likely be long-lasting. Efforts directed towards monitoring the onset and progression of distress and mental health disorders are needed to identify and prioritize at-risk populations. This study assesses the psychological well-being of the United States (US) general population during the early phase of the COVID-19 COVID-19 pandemic using validated patient-reported outcome measures (PROMs).MethodsA cross-sectional study design was used. Adults (18 years or older) who could read and write in English were recruited through Prolific in May 2020. Participants completed a REDCap survey including demographic and health-related questions and three PROMs measuring global health (PROMIS-10 Global Health), anxiety [Generalized Anxiety Disorder Scale-7 (GAD-7)], and depression [Patient Health Questionnaire-9 (PHQ-9)]. A multivariable linear regression was used to identify key factors associated with worse psychological well-being.ResultsMean age of the 2023 participants was 31.92 ± 11.57 years (range, 18–82). Participants were mainly White (64.7%, n = 1309), female (52.2%, n = 1057), working full-time before the pandemic (43.5%, n = 879), and completed a college, trade, or university degree (40.7%, n = 823). Most participants reported mild to severe anxiety (57.3%, n = 1158) and depression (60%, n = 1276) on the GAD-7 and PHQ-9, respectively. Patient characteristics associated with worse psychological well-being included: age ≤ 39 years, non-White, female or gender diverse, BMI ≥ 30, uninsured, annual income ≤ $49,999 (USD), lower educational attainment, and belief that COVID-19 is deadlier than flu.ConclusionPROMs can be used to assess and monitor psychological well-being during the COVID-19 pandemic and to inform the planning and delivery of targeted public health interventions to support at-risk populations.

Quality of Life in Patients with Clinically Severe Von Willebrand Disease: Interim Analysis of Athn 9: A Natural History Study for People with Severe Von Willebrand Disease (VWD)

Background: Von Willebrand Disease (VWD) is the most common inherited bleeding disorder, which results from either a quantitative (Type 1 or 3) or qualitative (Type 2) defect in von Willebrand Factor (VWF). Prior studies, largely focused on individuals with mild VWD and bleeding symptoms, have shown significant reductions in quality of life in patients with Von Willebrand disease. Because of the rarity less is known about individuals with severe forms of VWD or those with a severe bleeding phenotype. Aim: To report quality of life measures in participants with clinically severe VWD in the United States (US). Study Design and Methods: ATHN 9 Severe VWD Natural History Study is sponsored by the American Thrombosis and Hemostasis Network (ATHN) and is being conducted at 25 ATHN-affiliated sites across the US. ATHN 9 is an observational study focused on persons with clinically severe VWD treated with VWF factor on demand or for prophylaxis. Participants are identified by site investigators with a projected goal to enroll 130 individuals. Patients with severe VWD defined as type 3 VWD, or a VWF:RCo, VWF:GPIbM or VWF:Ag ≤ 30%, or persons with "clinically severe VWD" defined by VWF:RCo, VWF:GPIbM or VWF:Ag ≤ 40% and requiring recurrent use of factor concentrates, and prior enrollment in the ATHNdataset national surveillance data collection project are included. Participants with platelet-type or acquired VWD are excluded. Quality of life was assessed using PROMIS measures (PROMIS 25, PROMIS 25 Proxy, PROMIS 29) and the VWIQ at enrollment, annually, and at study exit. PROMIS-29 assesses seven different quality of life domains (physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference) and has been validated in adult populations. PROMIS measures in the general US population have a mean of 50 and standard deviation of 10. PROMIS-25 is a pediatric questionnaire assessing the same domains (except for sleep disturbance) and an accompanying proxy form for caregivers of participants <8 years of age. Baseline enrollment results are reported here. Results: Enrollment (baseline) PROMIS-29 forms were completed by 43 participants. At baseline, mean physical function was lower than the general population at 45.7 (p=0.005), and fatigue and pain interference were greater than the general population at 53.2 and 53 respectively (p=0.036 and 0.049 respectively). Individuals on continuous VWF factor prophylaxis (n=18) had significantly decreased physical function (p<0.01), and decreased ability to participate in social roles (p<0.01) than individuals on episodic treatment (n=19). Enrollment PROMIS-25 forms were completed for 26 participants, while PROMIS-25 proxy forms were completed for 19 participants. Mean enrollment scores for PROMIS-25 depression symptoms was lower than the general population at 44.4 (p=0.0004) and peer relationships were better than the general population at 54 (p=0.042). Mean enrollment scores for PROMIS-25 Proxy were lower than the general population for depression, fatigue, and pain interference at 41, 42.9, and 45.4 respectively (p<0.0001, p=0.002, and p=0.045 respectively). In contrast to the adult participants, no statistically significant differences were seen between pediatric participants on VWF factor prophylaxis versus episodic treatment. Discussion: Pediatric participants with clinically severe VWD reported less depression and better peer relationships than the general population, and parents of pediatric participants with VWD reported less depression, fatigue, and pain interference in their children compared to the general population. Patient-reported outcomes in adult participants were less encouraging with worse physical function, and more fatigue and pain interference compared to the general population. Adult participants on VWF factor prophylaxis had decreased physical function, and decreased ability to participate in social roles compared to adults treated episodically, perhaps secondary to disease severity and accumulation of bleed-related morbidity. No statistically significant differences were seen in quality of life outcomes between pediatric patients on VWF factor prophylaxis and those on episodic treatment.

Assessing per- and polyfluoroalkyl substances (PFAS) in sediments and fishes in a large, urbanized estuary and the potential human health implications

The primary source of chronic exposures to per- and polyfluoroalkyl substances (PFASs) in humans is through the ingestion of contaminated foods and drinking water, with fish and other seafood being a major contributor. Nevertheless, there is scant literature on the dietary exposure to PFASs for the general United States (U.S.) population. The Tampa Bay (Florida, USA) region has the highest population density in the State and communities and their attendant support services are arrayed in an urban to semi-rural continuum from the head of the Bay to the ocean mouth. Tampa Bay supports productive recreational and commercial fisheries, providing a diverse community of species. A variety of potential PFAS sources surround Tampa Bay including airports, industry, wastewater treatment plants, fire-fighting training areas and military installations. The objective of this study is to quantify PFASs in sediment and fishes collected from Tampa Bay to further estimate human health risks from dietary exposures. Sediment (n = 17) and fish (24 species, n = 140) were collected throughout Tampa Bay in 2020 and 2021 and analyzed for 25 PFAS compounds. Concentrations of PFASs in sediments and edible tissues of fish ranged from 36.8 to 2,990 ng kg-1 (dry weight) and 307 to 33,600 ng kg-1 (wet weight), respectively. Generally, levels were highest in Old Tampa Bay and decreased south towards the Gulf of Mexico. Profiles in both matrices were generally dominated by perfluorooctane sulfonic acid (PFOS) with variations by location. Estimated human health risks from the consumption of contaminated fish collected in Tampa Bay exceeded concentration thresholds for minimum risk levels (MRLs) and tolerable weekly intake (TWIs) values for adults and youths. Additionally, concentrations of PFOS in edible fish tissues of several recreationally important species collected in Tampa Bay exceeded consumption guideline levels established by several governmental agencies. In the current context, the elevated levels of PFAS in Tampa Bay and the exceedances of available thresholds for potential human health risks are a cause for concern and justify a more intensive examination especially for more heavily utilized species, particularly those used in subsistence-level fishing, which, as elsewhere may be significantly under documented.

Using percentiles in the interpretation of Patient-Reported Outcomes Measurement Information System scores: Guidelines for autism.

The objectives of this study were to (1) demonstrate the application of percentiles to advance the interpretation of patient-reported outcomes and (2) establish autism-specific percentiles for four Patient-Reported Outcomes Measurement Information System (PROMIS) measures. PROMIS measures were completed by parents of autistic children and adolescents ages 5-17 years as part of two studies (n=939 parents in the first study and n=406 parents in the second study). Data from the first study were used to develop autism-specific percentiles for PROMIS parent-proxy sleep disturbance, sleep-related impairment, fatigue, and anxiety. Previously established United States general population percentiles were applied to interpret PROMIS scores in both studies. Results of logistic regression models showed that parent-reported material hardship was associated with scoring in the moderate-severe range (defined as ≥75th percentile in the general population) on all four PROMIS measures (odds ratios 1.7-2.2). In the second study, the percentage of children with severe scores (defined as ≥95th percentile in the general population) was 30% for anxiety, 25% for sleep disturbance, and 17% for sleep-related impairment, indicating a high burden of these problems among autistic children. Few children had scores at or above the autism-specific 95th percentile on these measures (3%-4%), indicating that their scores were similar to other autistic children. The general population and condition-specific percentiles provide two complementary reference points to aid interpretation of PROMIS scores, including corresponding severity categories that are comparable across different PROMIS measures.

The pandemic effect: The outlook of lung transplantation

Lung transplant (LT) is a life-saving treatment for patients with end-stage lung disease. In the setting of COVID-19-associated acute respiratory distress syndrome (ARDS), LT emerged as a therapeutic option for select cases. It is challenging to determine the extent of the knowledge and interest the United States (US) general population has on LT as salvage therapy during and following the COVID-19 pandemic. It is the authors’ opinion that patient therapeutic education (PTE) can directly influence established practices by creating an open channel of communication based on needs and expectations for healthcare services. This perspective is a cursory reflection of the nuances between healthcare providers, their services, the interests and expectations of the general population, specifically on LT following COVID-19.The main endpoint of this study is to analyze the US general population's interest in LT as COVID-19 salvage therapy via the Google Trends (GT) web-kit tool.

Prescription medication use of United States military service members by therapeutic classification.

Background: This cross-sectional study investigated the prevalence of, and factors associated with, filled prescription medications (FPMs) among United States (US) service members (SMs). Methods: A stratified random sample of active duty SMs from the Air Force, Army, Marine Corps, and Navy was obtained from military workforce records. Participants (n = 26,680) completed a questionnaire on demographics, physical characteristics, and lifestyle factors and approved access to their FPM for the previous 6 months. FPMs were obtained from the military Pharmacy Data Transaction Service that included all prescription medications dispensed at military medical treatment facilities, abroad, at retail pharmacies in the US, and/or through mail-order programs. Results: About two-thirds (65%) of SMs had ≥1 FPM in the 6 months surveillance period. Central nervous system (CNS) agents had the highest prevalence (41%), followed by anti-infective agents (20%), eye/ear/nose/throat preparations (20%), gastrointestinal drugs (18%), autonomic drugs (17%), skin and mucous membrane agents (13%), antihistamine drugs (12%), respiratory tract agents (12%) and cardiovascular drugs (9%). Among CNS agents, overall prevalence of dispensed non-steroidal anti-inflammatory drug (NSAIDs) was 30%. The odds of any FPM was independently associated with female gender, older age, higher body mass index, former tobacco use (smoking and smokeless tobacco), lower alcohol consumption, and was highest among Army, lowest among Marine Corps personnel. Conclusion: In this sample of SMs, dispensing of prescription medication was high, especially NSAIDs, but dispensing of cardiovascular drugs was much lower compared to the general US population, likely because of the younger age and higher level of physical activity of SMs.

High prevalence of chronic viral hepatitis B and C in Minnesota Somalis contributes to rising hepatocellular carcinoma incidence.

BACKGROUNDChronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are known risk factors for liver disease, cirrhosis and hepatocellular carcinoma (HCC). There is substantial global variation in HBV and HCV prevalence resulting in variations in cirrhosis and HCC. We previously reported high prevalence of HBV and HCV infections in Somali immigrants seen at an academic medical center in Minnesota.AIMTo determine the prevalence of chronic viral hepatitis in Somali immigrants in Minnesota through a community-based screening program.METHODSWe conducted a prospective community-based participatory research study in the Somali community in Minnesota in partnership with community advisory boards, community clinics and local mosques between November 2010 and December 2015 (data was analyzed in 2020). Serum was tested for hepatitis B surface antigen, hepatitis B core antibody, hepatitis B surface antibody and anti-HCV antibody.RESULTSOf 779 participants, 15.4% tested positive for chronic HBV infection, 50.2% for prior exposure to HBV and 7.6% for chronic HCV infection. Calculated age-adjusted frequencies in males and females for chronic HBV were 12.5% and 11.6%; for prior exposure to HBV were 44.8% and 41.3%; and for chronic HCV were 6.7% and 5.7%, respectively. Seven participants developed incident HCC during follow up.CONCLUSIONChronic HBV and HCV are major risk factors for liver disease and HCC among Somali immigrants, with prevalence of both infections substantially higher than in the general United States population. Community-based screening is essential for identifying and providing health education and linkage to care for diagnosed patients.

Cancer risk and gammopathies in 2123 adults with Gaucher disease type 1 in the International Gaucher Group Gaucher Registry.

There are numerous reports of cancers in Gaucher disease (GD) from mostly small single‐center studies; however, precise risk estimates and cancer types involved have not been delineated. We conducted a study involving 2123 patients with GD type 1 (GD1) to assess the incidence of hematological malignancies, gammopathies, and solid tumors in an international observational study, the International Cooperative Gaucher Group Gaucher Registry (Clinicaltrials.gov: NCT00358943). Risk for cancer overall and for each type of malignancy was compared to the United States (US) population using the Surveillance, Epidemiology, and End Results database. Natural history of gammopathy was determined through assessing the progression from a diagnosis of monoclonal gammopathy of unknown significance (MGUS) to multiple myeloma (MM). Risk for hematological malignancies was more than four times higher than expected compared to the general population: non‐Hodgkin lymphoma was approximately three times higher; MM was approximately nine times higher. Age‐specific incidence rates of MGUS were unexpectedly high among younger patients. The 10‐year cumulative incidence of MM after diagnosis of MGUS was 7.9%, comparable to the general population. Compared to the general US population, GD1 patients were at higher risk for solid malignancies of liver (2.9 times), kidney (2.8 times), melanoma (2.5 times), and breast (1.4 times). Colorectal, prostate, and lung cancer risks were lower than expected. These findings help advance care of patients with GD1 by supporting recommendations for individualized monitoring for malignancies and antecedents such as MGUS for MM and provoke important questions of the role of glucosylceramide and related sphingolipids in cancer biology.

A Smoking Cessation Mobile App for Persons Living With HIV: Preliminary Efficacy and Feasibility Study.

BackgroundThe prevalence of smoking in the United States general population has gradually declined to the lowest rate ever recorded; however, this has not been true for persons with HIV.ObjectiveWe conducted a pilot test to assess the feasibility and efficacy of the Lumme Quit Smoking mobile app and smartwatch combination with sensing capabilities to improve smoking cessation in persons with HIV.MethodsA total of 40 participants were enrolled in the study and randomly assigned 1:1 to the control arm, which received an 8-week supply of nicotine replacement therapy, a 30-minute smoking cessation counseling session, and weekly check-in calls with study staff, or to the intervention arm, which additionally received the Lumme Quit Smoking app and smartwatch.ResultsOf the 40 participants enrolled, 37 completed the follow-up study assessments and 16 used the app every day during the 56-day period. During the 6-month recruitment and enrollment period, 122 people were screened for eligibility, with 67.2% (82/122) deemed ineligible. Smoking criteria and incompatible tech were the major reasons for ineligibility. There was no difference in the proportion of 7-day point prevalence abstinence by study arm and no significant decrease in exhaled carbon monoxide for the intervention and control arms separately. However, the average exhaled carbon monoxide decreased over time when analyzing both arms together (P=.02).ConclusionsResults suggest excellent feasibility and acceptability of using a smoking sensor app among this smoking population. The knowledge gained from this research will enable the scientific community, clinicians, and community stakeholders to improve tobacco cessation outcomes for persons with HIV.Trial RegistrationClinicalTrials.gov NCT04808609; https://clinicaltrials.gov/ct2/show/NCT04808609

Competing risk analysis of cardiovascular death in patients with primary gallbladder cancer.

Developments in medical technology are resulting in continuous decreases in the cancer mortality rate of patients with gallbladder cancer, while non-cancer deaths in cancer patients are becoming more common. The main cause of this is cardiovascular mortality (CVM). The purpose of this study was to determine the CVM risk in patients with primary gallbladder cancer (PGC). We extracted information on patients in the SEER database who were diagnosed with PGC from 2004 to 2015, compared CVM in patients with PGC with the general United States population, and calculated standardized mortality rates (SMRs) and the absolute excess risk. A competing risks model was used to identify and analyze the independent risk factors for cardiovascular death in patients with PGC. This study included 5925 patients, 247 of whom died from cardiovascular disease. The SMR of cardiovascular death in patients with PGC was 15.84 (95% confidence interval: 15.83-15.85), and the SMR was slightly lower in male than female patients. The competing risks analysis indicated that age, marital status, cancer cell differentiation, chemotherapy status, and year of diagnosis were risk factors for cardiovascular death in patients with PGC. The CVM risk is considerably higher in patients with PGC than in the general population. It is therefore very necessary to apply cardioprotective interventions to patients with PGC.

Guideline discordant care in patients with metastatic germ cell tumors.

Despite high curability, patients with metastatic germ cell tumors (GCT) in the United States general population persistently face inferior outcomes compared with those treated in specialty referral centers. We characterized guideline discordant management in patients with metastatic GCT who experienced relapse after first-line chemotherapy and compared those who were initially treated in community practices vs. academic referral centers. Retrospective analysis of 53 patients with relapsed GCT between 2005 and 2018. First-line GCT management was assessed against the National Comprehensive Cancer Network guidelines. Guideline discordant management, predictors of discordance, and associations with outcomes were assessed. Of 53 patients with relapsed GCT, 34% received guideline discordant care in the first-line setting. Guideline discordant care was more prevalent in patients initially treated in community practices (12/30, 40%) vs. those initially treated in academic centers (3/22, 14%), though in multivariate logistic regression, this difference was not statistically significant (odds ratio: 4.07, P = 0.08). Most patients in community settings who received guideline discordant care were undertreated (10/12, 83%). There were 3 major reasons for guideline discordant care: (1) failure to resect residual masses after chemotherapy (27%, 4/15), (2) mismanagement of chemotherapy-related adverse events (27%, 4/15), and (3) under staging at diagnosis, resulting either insufficient chemotherapy regimen intensity (13%, 2/15) and/or inappropriately receiving primary surgical resection for metastatic disease (20%, 3/15). Under treatment was identified in nearly half of patients initially treated in a community setting who later developed relapsed GCT. Referral to specialized centers for a second opinion should be considered for all metastatic GCT patients in the first-line setting and all patients with post-chemotherapy residual disease. More effective methods should be developed to facilitate second opinions from expert centers in the United States.

Performing an Organizational Health Literacy Assessment in a Shelter Serving People with Mental Illness.

Background:Health literacy research and practice are constantly evolving. Recent inquiry has highlighted the burdensome literacy demands faced by people with serious mental illness (SMI). Systems, organizational operations, and structures can play a role in decreasing literacy demand, thereby reducing unnecessary challenges for people with SMI.Brief Description of Activity:An organizational health literacy assessment was conducted to explore literacy demands in one mental health shelter and revealed best practice action steps for improving the literacy environment.Implementation:The assessment included an exploration of the shelter environment using The Health Literacy Environment Activity Packet, First Impressions & Walking Interview, and a commonly used shelter document using the Simple Measure of Gobbledygook (SMOG), Suitability Assessment of Materials (SAM), and Centers for Disease Control and Prevention (CDC) Index.Results:The literacy demands of the shelter environment and a frequently used document exceeded the literacy skills of people with SMI. Environment assessment revealed environmental facilitators (e.g., welcoming atmosphere) and barriers (e.g., unclear signage). Document assessment also revealed facilitating factors and barriers. SMOG scores ranged from 11.25 to 11.80 (median: 11.38), meaning 11th to 12th grade-level reading skills are required to understand, use, and take action on the document's content. A SAM score of 50% (adequate) and a CDC Index score of 42.1 (revise and improve) reveal materials contain both facilitating factors (e.g., chunked sections) and barriers (e.g., jargon, mismatched graphics) to use.Lessons Learned:The mismatch between system demands and the literacy skills of people with SMI is more profound than that of the general United States population. Organizational health literacy assessments are achievable and useful for both immediate and long-term action aimed at understanding and improving the organizational health literacy of mental health spaces. Further work is needed to explore the role of behavioral health services in addressing the institutional and programmatic literacy demands that inhibit treatment and recovery. [HLRP: Health Literacy Research and Practice. 2022;6(3):e167–e174.]Plain Language Summary:An organizational health literacy assessment reveals how system demands can be changed to better serve intended users. Engaging in mental health, recovery, and treatment services requires complex literacy skills. Generally, the U.S. adult population does not have the skills to meet such demands, and this is especially true among public mental health service users.

A comparison of anxiety symptoms and correlates of anxiety in people with progressive and relapsing-remitting multiple sclerosis

BackgroundAnxiety appears to be more prevalent in people with multiple sclerosis (MS) than in the general population, though it is unclear if anxiety varies by MS disease course. There are experiences unique to each disease course that might increase the likelihood of anxiety. Additionally, the majority of research in MS has focused on people with relapsing-remitting MS (RRMS), while the experiences of people with progressive forms of MS are understudied. This study examined anxiety in people with progressive MS (PMS) and examined group differences in anxiety compared to people with RRMS, and assessed unique and common correlates of anxiety in people with PMS and RRMS. MethodsSecondary analysis of data from the fourth survey in a longitudinal study of quality of life in people with physical disabilities. The current study included a subset of participants with MS. Anxiety level was measured by the 4-item Patient-Reported Outcomes Measurement Information System – Anxiety Short Form T-score. T-test and chi-square analyses were used to compare groups. Correlates of anxiety were tested by examining the interaction of MS subtype (PMS and RRMS) and each potential correlate in multiple regression models with bootstrapping. ResultsParticipants were 464 adults with MS (PMS n = 183; RRMS n = 281) who were predominately female, non-Hispanic white, and not employed with a mean age of 56.9 ± 10.3 years and disease duration of 17.5 ± 9.3 years. On average, participants with PMS reported anxiety symptoms (50.6 ± 8.6) that were comparable to those in the United States general population and statistically lower than participants with RRMS (52.8 ± 9.5; p = .01). Across MS courses, common factors associated with greater anxiety symptoms were shorter disease duration, lower household income, greater speech and/or swallowing problems, and current smoking (tobacco), adjusted R2 = .19, F(4, 391) = 22.68, p < .001. There was no evidence of unique correlates of anxiety symptoms in participants with either MS course. ConclusionsIn this community sample, people with MS, regardless of disease course, reported similar levels of anxiety to the United States general population. This is inconsistent with prior literature that largely involves clinical samples, suggesting a need for further research with community samples of individuals with MS. This discrepancy may also be due to measurement differences between studies (e.g., screen versus symptom measures). Participants with RRMS reported greater average anxiety compared to those with PMS. This statistically significant difference was small and not clinically significant, indicating the need for further examination and replication. Overall, the findings highlight the wide heterogeneity of anxiety presentation within people with MS and identify potential factors to improve conceptualization and treatment of anxiety in this population. Further research is needed with community and clinical samples to understand anxiety in MS as well as risk and protective factors to improve conceptualization and treatment of anxiety in this population.

Prevalence of hyperglycemia in masters athletes.

BackgroundAgeing is associated with decreased physical activity, obesity and subsequently an increased risk of developing type 2 diabetes mellitus (T2dm). Master athletes (MA) have initiated exercise or sport later in life or pursued a physically active lifestyle for an extended period. Subsequently, MAs have been proposed as a model of successful ageing as this active lifestyle is associated with health benefits including decreased health risk of chronic diseases and a reduction in premature mortality. Given long-term physical activity/exercise has previously been shown to be protective against hyperglycemia, a risk factor for T2dm, it is plausible that MA may have protective benefit against developing hyperglycemia. Therefore, the aim of this study was to investigate the prevalence of hyperglycemia via fasting plasma glucose (FPG) in MAs competing at the World Masters Games (WMG).MethodsThis cross-sectional, observational survey utilized an online survey using open-source web-based software was used to investigate MAs physiological and medical-related parameters. Over 28,000 MAs competed in the WMG, of which 8,072 MAs completed the survey. Of these MAs, a total of 486 (males 277, females 209; range 27 to 91 years, mean age 55.1 ± 10.2 years) attained recent pathology results which included FPG which was subsequently analyzed for this study. FPG and other outcome variables were compared between genders and to the Australian and United States general population.ResultsMean FPG for MAs was 5.03 mmol (±1.2, 95% CI [4.9–5.1] mmol) with majority (75.5%) of MAs reporting a normal (<5.5 mmol) FPG, followed by pre-diabetes (20.2%, >5.51 to <5.99 mmol) and abnormal (4.3%, >7.0 mmol). There was no significant difference (P = 0.333) in FPG between genders however, males had a slightly higher (+2.1%) FPG as compared to females (5.08 ± 1.2 mmol (95% CI [4.9–5.22] mmol) versus 4.98 ± 1.1 mmol (95% CI 4.8-5.1 mmol)). The majority of males (71.8%) and females (80.3%) were classified with a normal FPG. With regard to an abnormal FPG level, only 4.0% of males and 4.9% of females were classified abnormal which was suggestive of undiagnosed T2dm. With regard to age by decade, there was no significant difference (P = 0.06–1.00) between age groups and no relationship between the MAs’ age and FPG (r = .054, P = 0.24). As a group, MAs had a significantly lower FPG as compared to the Australian (−3.2%, P = 0.005) and United States general populations (−13.9%, P < 0.001).ConclusionsMost, however not all, MAs were found to have normal glycaemia, with only a small percentage indicating a risk of developing T2dm (i.e., impaired fasting glucose) and a smaller percentage identified with an abnormal FPG, suggestive of T2dm. These findings suggest MAs appear to be at low metabolic risk for developing T2dm based upon FPG and the physical activity/exercise they complete as MAs may indeed be protective against hyperglycemia whilst maintaining an active lifestyle.

Association of Beta-2-Microglobulin With Coronary Heart Disease and All-Cause Mortality in the United States General Population.

Few prospective studies explored the association of beta-2-microglobulin (B2M) with coronary heart disease (CHD) mortality. The primary objective of this study was to examine the association of serum B2M with CHD and all-cause mortality. This is a prospective cohort study of a nationally representative sample of 4,885 adults, aged 40–85 years, who participated in the National Health and Nutrition Examination Survey (NHANES III) from 1988 to 1994. The relationships between B2M and CHD and all-cause mortality were estimated using Cox proportional hazards regression models. During a median follow-up of 15.5 years, 845 CHD and 3,388 all-cause deaths occurred among 4,885 participants [2,568 women (55.7%); mean (S.D.) age, 66.4 (12.5) years], respectively. In the unadjusted model, B2M concentration was strongly linearly associated with CHD and all-cause mortality (p-trend < 0.001). After adjusting multivariable factors, a positive linear association between B2M and all-cause mortality was still observed (H.R. for Q4 vs. Q1 5.90; 95% CI: 5.31–6.57; p-trend < 0.001). In the multivariable adjustment model, B2M was significantly associated with an increased risk of CHD mortality (H.R. for Q4 vs. Q1 2.72; 95% CI: 2.07–3.57; p-trend < 0.001). In the stratified analyses, the associations of B2M with CHD and all-cause mortality varied by risk factors, such as age, smoking status, and history of hypertension. The findings suggest a significant relationship between the higher serum B2M concentration and increased risk for CHD and all-cause mortality. Further large-scale follow-up studies are also needed to validate this association.

Stressful life events and social support among pregnant Marshallese women

IntroductionWomen from racial and ethnic minority groups in the United States are disproportionately likely to experience adverse perinatal outcomes such as preterm birth, low birthweight infants, and infant mortality. Previous research has demonstrated that exposure to stressful life events and social support may influence perinatal outcomes. Although studies have documented stressful life events and social support for the general United States population and minority groups, less is known about the experiences of Pacific Islander women in the United States, and no prior studies have documented these experiences in Marshallese Pacific Islander women.MethodsThe present study examined data collected from pregnant Marshallese women (n = 67) in northwest Arkansas participating in a women’s health program using descriptive analyses (means, standard deviations, proportions).ResultsResults indicated a high prevalence of three stressful life events: experiencing a family member going into the hospital (35.8%), someone close to them dying (29.9%), and being unable to pay bills (53.7%). Food insecurity was higher than previously reported for pregnant women or Pacific Islanders (83.7%). Social support was high among the sample. A majority of women reported receiving help with daily chores (86.6%), help when sick (88.1%), and support on how to deal with personal problems (85.1%).DiscussionThis study is the first to document the prevalence of stressful life events and social support in a sample of pregnant Marshallese women living in the United States. The findings provide important information to guide efforts to reduce adverse perinatal outcomes in a Pacific Islander population.

The effect of food access on type 2 diabetes control in patients of a New Orleans, Louisiana, clinic

BackgroundThe U.S. Department of Agriculture (USDA) classifies numerous neighborhoods in New Orleans, Louisiana, as food deserts or areas with inadequate access to good quality foods. With approximately 35% of all patients with type 2 diabetes (T2DM) establishing disease control, we hypothesize those living in food deserts will have increased difficulty in controlling T2DM. The purpose of this study is to evaluate the effect of food deserts on glycemic control in patients with T2DM. ObjectiveThe purpose of this study is to analyze the effect of food access on T2DM control in patients at a diabetes management clinic compared with the national average of T2DM control. MethodsEligible records for review included patients residing in a USDA-determined food desert with a T2DM diagnosis. The primary end point was the proportion of patients with controlled T2DM. T2DM control was defined as glycosylated hemoglobin values less than 7% and less than 7.5% in patients older than 65 years. Records were retrieved for review between the dates of February 2017 and February 2020. ResultsA total of 109 patient records were reviewed. Of these, 23 patients (21%) achieved glycemic control. There was a 14% difference (35%-21%) between the food desert patients with T2DM and the general United States population of patients with T2DM (P = 0.030). ConclusionThis study underscores the potential implications of limited food access on patients’ abilities to manage chronic conditions like T2DM. Clinicians who work in resource-limited settings or with marginalized patient populations have a responsibility to consider food access and other health disparities when creating realistic and feasible treatment goals.

GoogleTrends as a patient therapeutic education resource on extracorporeal life support: What do patients want to know?

Extracorporeal membrane oxygenation (ECMO) is implemented as rescue therapy in COVID-19 related acute distress respiratory syndrome (ARDS) and refractory hypoxemia. Google Trends (GT) is an ongoing-developing web kit providing feedback on specific population's interests. This study uses GT to analyze the United States (US) general population interest in ECMO as COVD-19/ARDS salvage therapy. GT was used to access data searched for the term ECMO and COVID-19. The gathered information included data from March 2020 to July 2021 within US territories. Search frequency, time intervals, sub-regions, frequent topics of interest, and related searches were analyzed. Data were reported as search frequency on means, and a value of 100 represented overall peak popularity. The number of Google searches related to the terms ECMO and COVID-19 has surged and sustained interest over time ever since the initial reports of COVID-19 in the US, from an initial mean of 34% in March 2020 to a 100% interest by April 2020, resulting in an up-to-date overall average of 40% interest. Over time West Virginia, Gainesville, and Houston, lead the frequency of searches in sub-region, metro and city areas, respectively. Top search terms by frequency include: ECMO machine, COVID ECMO, what is ECMO, ECMO treatment and VV ECMO. Parallel to this, the related rising terms are: COVID ECMO, ECMO machine COVID, ECMO for COVID, ECMO machine coronavirus, and ECMO vs ventilator. Seemingly, medical-relevant websites fail to adequately address these for patient therapeutic education (PTE) purposes. GT complements the understanding of interest in ECMO for COVID-19. When properly interpreted, the use of these trends can potentially improve on PTE and therapy awareness via specific medical relevant websites.

Sticky Floor and Glass Ceilings in Academic Medicine: Analysis of Race and Gender.

PurposeThis paper examines the changes in the representation of women and racial minorities in academic medicine, compares the proportion of minorities in medicine and the general United States (US) population, and discusses potential explanations for observed trends.MethodsA retrospective cross-sectional analysis of the Association of American Medical Colleges (AAMC) database was done and used to collect data on the gender and race of physicians in academic medicine. Data was collected for instructors, assistant professors, associate professors, full professors, and chairpersons from 2007 to 2018, and trends were presented.ResultsWhite physicians represented most academic physicians at every academic level, peaking in proportion at 82.74% of chairpersons and were lowest at the level of instructor at 59.30%. A similar distribution existed when gender was compared, with men comprising 84.67% of chairpersons and forming the majority at levels of full, associate, and assistant professors. However, most physicians at the level of instructors are women at 55.44%.ConclusionsThough women and racial minorities have gained greater representation in academic medicine over the past decade, high-level academic positions are not as accessible to them. Existing efforts of advocacy for women and minority races have proven fruitful over the past decade, but much more work needs to be done.
