Closed-Loop Insulin Delivery Effects on Glycemia During Sleep and Sleep Quality in Older Adults with Type 1 Diabetes: Results from the ORACL Trial.

Sleep-related effects of closed-loop therapy among older adults with type 1 diabetes have not been well established. In the OldeR Adult Closed-Loop (ORACL) randomized, crossover trial of first-generation closed-loop therapy (MiniMed 670G), participants wore actigraphy and completed sleep diaries for 14-day periods at stage end. During objectively measured sleep (actigraphy) with closed-loop versus sensor-augmented pump therapy, glucose time-in-range 70-180 mg/dL (3.9-10.0 mmol/L) was greater (90.3% vs. 78.7%, respectively; difference 8.2 percentage points [95% confidence interval {CI} 1.5 to 13.0]; P = 0.008), and there were fewer sensor hypoglycemia episodes (18 vs. 43, respectively; incident rate ratio 0.40 [95% CI 0.20 to 0.55]; P = 0.007). Sleep quality recorded daily was worse with closed-loop therapy (P = 0.006); Pittsburgh Sleep Quality Index did not differ. There were 30% more system alarms during monitored sleep with closed-loop therapy (P < 0.001). First-generation closed-loop therapy has important glycemic benefits during sleep for older adults, with deterioration in some sleep quality measures. Sleep quality warrants prioritization and investigation during advancement of closed-loop technology.

Upload and Review of Insulin Pump and Glucose Sensor Data by Adults with Type 1 Diabetes: A Clinic Audit.

Devices have facilitated improvement in glycemia in individuals with type 1 diabetes mellitus (T1DM), but self-management remains key. It is unclear whether people review their device data before clinic appointment. We assessed this by a survey. T1DM adults using glucose sensors and/or insulin pumps attending an Australian public hospital (diabetes clinics >4 months) were prospectively surveyed. The percentage who uploaded and reviewed their data was determined and their interest in education facilitating understanding of their device data was assessed. Of 138 adults (100% participation rate), 79% uploaded and 32% reviewed their device data before their clinic appointments. Individuals using pumps with sensors were most likely to review their data. Median HbA1c levels were lower in those who did versus did not review their device data (50.8 vs. 61.8 mmol/mol, P = 0.0001). Most (89%) were interested in education. Although diabetes technology has improved glycemia in T1DM, the benefits may be maximized through device-specific education programs enhancing self-management.

COVID-19 vaccine hesitancy in the UK: a longitudinal household cross-sectional study.

BACKGROUND: The approved COVID-19 vaccines have shown great promise in reducing disease transmission and severity of outcomes. However, the success of the COVID-19 vaccine rollout is dependent on public acceptance and willingness to be vaccinated. In this study, we aim to examine how the attitude towards public sector officials and the government impact vaccine willingness. The secondary aim is to understand the impact of ethnicity on vaccine-willingness after we explicitly account for trust in public institutions. METHODS: This cross-sectional study used data from a UK population based longitudinal household survey (Understanding Society COVID-19 study, Understanding Society: the UK Household Longitudinal Study) between April 2020-January 2021. Data from 22,421 participants in Waves 6 and 7 of the study were included after excluding missing data. Demographic details in addition to previous survey responses relating to public sector/governmental trust were included as covariates in the main analysis. A logit model was produced to describe the association between public sector/governmental mistrust and the willingness for vaccination with interaction terms included to account for ethnicity/socio-economic status. RESULTS: In support of existing literature, we identified those from BAME groups were more likely to be unwilling to take the COVID-19 vaccine. We found that positive opinions towards public sector officials (OR 2.680: 95% CI 1.888 - 3.805) and the UK government (OR 3.400; 95% CI 2.454-4.712) led to substantive increase in vaccine willingness. Most notably we identified this effect to vary across ethnicity and socio-economic status with those from South Asian background (OR 4.513; 95% CI 1.012-20.123) and possessing a negative attitude towards public officials and the government being the most unwilling to be vaccinated. CONCLUSIONS: These findings suggests that trust in public sector officials play a key factor in the low vaccination rates particularly seen in at-risk groups. Given the additional morbidity/mortality risk posed by COVID-19 to those from lower socio-economic or ethnic minority backgrounds, there needs to be urgent public health action to review how to tailor health promotion advice given to these groups and examine methods to improve trust in public sector officials and the government.

The interaction of ethnicity and deprivation on COVID-19 mortality risk: a retrospective ecological study.

Black, Asian and Minority Ethnic (BAME) populations are at an increased risk of developing COVID-19 and consequentially more severe outcomes compared to White populations. The aim of this study was to quantify how much of the disproportionate disease burden can be attributed to ethnicity and deprivation as well as its interaction. An ecological study was conducted using data derived from the Office for National Statistics data at a Local Authority District (LAD) level in England between 1st March and 17th April 2020. The primary analysis examined how age adjusted COVID-19 mortality depends on ethnicity, deprivation, and the interaction between the two using linear regression. The secondary analysis using spatial regression methods allowed for the quantification of the extent of LAD spillover effect of COVID-19 mortality. We find that in LADs with the highest deprivation quartile, where there is a 1 percentage point increase in "Black-African (regression coefficient 2.86; 95% CI 1.08-4.64)", "Black-Caribbean (9.66: 95% CI 5.25-14.06)" and "Bangladeshi (1.95: 95% CI 1.14-2.76)" communities, there is a significantly higher age-adjusted COVID-19 mortality compared to respective control populations. In addition, the spatial regression results indicated positive significant correlation between the age-adjusted mortality in one LAD and the age-adjusted mortality in a neighbouring LAD, suggesting a spillover effect. Our results suggest targeted public health measures to support those who are deprived and belong to BAME communities as well as to encourage restricted movement between different localities to limit disease propagation.

Relapse of Juvenile Idiopathic Arthritis-Associated Uveitis after Discontinuation of Immunomodulatory Therapy.

Purpose: To assess treatment outcomes in juvenile idiopathic arthritis (JIA)-associated uveitis and relapse rates upon discontinuation of immunomodulatory therapy (IMT). Methods: Medical records of patients with JIA-associated uveitis seen at the University of Illinois at Chicago and the F.I. Proctor Foundation uveitis clinics from September 14, 1988 to January 5, 2011 were reviewed. The main outcome was time to relapse after attempting to discontinue IMT.Results: Of 66 patients with JIA-associated uveitis, 51 (77%) received IMT as either sole or combination therapy. Of a total of 51, 41 (80%) patients achieved corticosteroid-sparing control. Attempts were made to discontinue treatment in 19/51 (37%) patients. Of a total of 19 patients, 13 (68%) attempting to discontinue IMT relapsed, with a median time to relapse of 288 days from the time of attempted taper/discontinuation (IQR: 108-338).Conclusions: Corticosteroid-sparing control of inflammation was achieved in the majority of patients; however, attempts to stop IMT were often unsuccessful. Close follow-up of patients after discontinuation of therapy is warranted.

Recording patient bodyweight in hospitals: are we doing well enough?

Recording patient weight is a standard practice for all hospital admissions, with this measurement influencing other daily practices that rely on the delivery of safe and effective patient care. Patient weight is important in the areas of medication prescribing, fluid balance and assessment of nutrition. In particular, prescribing narrow therapeutic index medications may result in significant harm as a potential consequence of inaccurate dosing. Despite its importance, it is evident that bodyweight measurements are recorded in only 13.5-55% of hospital patients, in a variety of settings including the emergency department, intensive care unit, medical and surgical wards. Barriers to compliance of healthcare staff include additional workload, patient handling and availability of appropriate weighing equipment. Hospitals and patients would benefit from enhancing compliance with the systematic weighing of patients, staff training and removing barriers to performing this task.

Bacterial and viral co-infections complicating severe influenza: Incidence and impact among 507 U.S. patients, 2013-14.

BACKGROUND: Influenza acts synergistically with bacterial co-pathogens. Few studies have described co-infection in a large cohort with severe influenza infection. OBJECTIVES: To describe the spectrum and clinical impact of co-infections. STUDY DESIGN: Retrospective cohort study of patients with severe influenza infection from September 2013 through April 2014 in intensive care units at 33 U.S. hospitals comparing characteristics of cases with and without co-infection in bivariable and multivariable analysis. RESULTS: Of 507 adult and pediatric patients, 114 (22.5%) developed bacterial co-infection and 23 (4.5%) developed viral co-infection. Staphylococcus aureus was the most common cause of co-infection, isolated in 47 (9.3%) patients. Characteristics independently associated with the development of bacterial co-infection of adult patients in a logistic regression model included the absence of cardiovascular disease (OR 0.41 [0.23-0.73], p=0.003), leukocytosis (>11K/µl, OR 3.7 [2.2-6.2], p<0.001; reference: normal WBC 3.5-11K/µl) at ICU admission and a higher ICU admission SOFA score (for each increase by 1 in SOFA score, OR 1.1 [1.0-1.2], p=0.001). Bacterial co-infections (OR 2.2 [1.4-3.6], p=0.001) and viral co-infections (OR 3.1 [1.3-7.4], p=0.010) were both associated with death in bivariable analysis. Patients with a bacterial co-infection had a longer hospital stay, a longer ICU stay and were likely to have had a greater delay in the initiation of antiviral administration than patients without co-infection (p<0.05) in bivariable analysis. CONCLUSIONS: Bacterial co-infections were common, resulted in delay of antiviral therapy and were associated with increased resource allocation and higher mortality.

Severe Influenza in 33 US Hospitals, 2013-2014: Complications and Risk Factors for Death in 507 Patients.

BACKGROUND: Influenza A (H1N1) pdm09 became the predominant circulating strain in the United States during the 2013-2014 influenza season. Little is known about the epidemiology of severe influenza during this season. METHODS: A retrospective cohort study of severely ill patients with influenza infection in intensive care units in 33 US hospitals from September 1, 2013, through April 1, 2014, was conducted to determine risk factors for mortality present on intensive care unit admission and to describe patient characteristics, spectrum of disease, management, and outcomes. RESULTS: A total of 444 adults and 63 children were admitted to an intensive care unit in a study hospital; 93 adults (20.9%) and 4 children (6.3%) died. By logistic regression analysis, the following factors were significantly associated with mortality among adult patients: older age (>65 years, odds ratio, 3.1 [95% CI, 1.4-6.9], P=.006 and 50-64 years, 2.5 [1.3-4.9], P=.007; reference age 18-49 years), male sex (1.9 [1.1-3.3], P=.031), history of malignant tumor with chemotherapy administered within the prior 6 months (12.1 [3.9-37.0], P<.001), and a higher Sequential Organ Failure Assessment score (for each increase by 1 in score, 1.3 [1.2-1.4], P<.001). CONCLUSION: Risk factors for death among US patients with severe influenza during the 2013-2014 season, when influenza A (H1N1) pdm09 was the predominant circulating strain type, shifted in the first postpandemic season in which it predominated toward those of a more typical epidemic influenza season.

Association of individual and systemic barriers to optimal medical care in people living with HIV/AIDS in Miami-Dade County.

Barriers to retention in HIV care are detrimental to patients' progress along the HIV continuum of care. Previous literature has focused on individual, client-level barriers, and interventions to address them. In contrast, less work has examined the role of system-level barriers on HIV care outcomes. This study seeks to understand how individual and systemic barriers individually are associated with clinic appointment attendance and virologic suppression in HIV-infected patients attending the largest HIV clinic in Miami-Dade, FL. In addition, we examined the synergistic effects of these barriers as potential syndemic factors on these health outcomes. Barriers to clinic attendance were determined in a face-to-face study interview with 444 HIV-infected outpatients (187 regular attenders, 191 irregular attenders, and 66 nonattenders) identified from electronic medical records. Compared with the other attendance groups, nonattenders had higher viral loads, were less likely to be virologically suppressed, had lower CD4 counts, had higher depressive symptoms, life chaos, lower quality of life, and higher rates of food insecurity, and recent drug use. Additionally, nonattenders compared with regular attenders had lower physician relationship ratings, had lower medical information clarity and more often reported transportation as a barrier to clinic attendance. When viewed as a syndemic, compared with patients not reporting any barriers, patients with 3 or more individual-level barriers were more likely to have a detectable viral load (odds ratio = 3.60, 95% CI: 1.71 to 7.61). Our findings suggest that patients presenting to the clinic with multiple barriers should be prioritized for assistance and future interventions to improve retention in care. Interventions should address multiple individual and system-level barriers simultaneously with particular attention to addressing depressive symptoms, organizational skills, relationship with the physician, and HIV-related health education.

A cross-national study to compare the knowledge, attitudes, perceptions of sexually transmitted diseases and the sexual risk behaviors of Latino adolescents.

BACKGROUND: Adolescents are at high risk of acquiring sexually transmitted diseases (STDs). However, little is known about differences in knowledge and risk behaviors across nationalities. The objective of this study was to assess and compare the knowledge and perceptions of STDs and the sexual risk behaviors in Latino adolescents in the United States (US) and the Dominican Republic (DR). METHODS: A survey was administered to 364 high school students after obtaining parental consent. The questionnaire asked about demographics, sources of STD information, risk behaviors, and knowledge of syphilis, gonorrhea, and human immunodeficiency virus (HIV). Mean percentage scores were calculated to compare correct responses by nationality, gender, and sexual activity. Predictors of self-reported high risk sexual behavior were identified by multivariable logistic regression analysis. RESULTS: In all, 242 (66%) US and 122 (34%) DR students were interviewed. Of these, 52% were males. Median age was 15 years (range, 13-18). Sexual activity was reported by 40% of the participants and did not differ by gender (p=0.43) or national origin (p=0.53), although it was greater for adolescents older than 15 years of age (60% vs. 35%, p<0.001). US students identified abstinence as an effective STD prevention method more often than their counterparts (p=<0.001). Knowledge of specific STDs was higher in girls (p=0.002) and Dominicans (p=0.003). Predictors of high risk behavior were male gender (OR

A rare case of prototheca algaemia in a patient with systemic lupus erythematosus and recent belimumab infusion.

Novel agents for the treatment of immune-mediated diseases such as systemic lupus erythematosus (SLE) have been increasingly used as an alternative to or in combination with conventional therapies. Belimumab, a human monoclonal antibody that inhibits B-cell activating factor (BAFF), has demonstrated efficacy in moderate-to-severe SLE with similar adverse effects when compared to other biologic agents and conventional SLE therapies. Here, we describe a woman with SLE and diabetes mellitus (DM) on immunosuppressive therapy for five years who was admitted to the hospital for pneumonia but had a complicated hospital course with multiple infections and, most notably, a nosocomial algaemia due to Prototheca wickerhamii, which was treated successfully with amphotericin B. She had recently received three belimumab infusions as an outpatient prior to admission to the hospital. To the best of our knowledge no cases of human protothecosis in patients receiving belimumab have been described in the English literature; however, unusual infections have to be considered in all patients undergoing immunosuppressive therapies who persist with fever despite conventional antimicrobials.

Clinical features and diagnostic evaluation of biopsy-proven ocular sarcoidosis.

OBJECTIVES: To compare the clinical characteristics of uveitic sarcoidosis in African American and non-African American patients with biopsy-proven sarcoidosis and to determine which diagnostic test results were most often suggestive of sarcoidosis in patients who were ultimately diagnosed as having the disease. METHOD: Retrospective review of consecutive patients with biopsy-proven sarcoidosis evaluated by the uveitis service between 1989 and 2009. RESULTS: A total of 63 patients with uveitic sarcoidosis were identified: 39 (62%) were African American (P <.001) and 43 (68%) were female. African American patients presented at an earlier age (P <.001) and were more likely to have granulomatous anterior segment inflammation (P <.001). The levels of serum markers angiotensin-converting enzyme and lysozyme were elevated in 40% and 42% of patients tested, respectively. The levels of at least 1 marker were elevated in 18 patients (58%). Imaging study results were reported as consistent with sarcoidosis in 25 patients (69%) who underwent chest radiography and in 19 patients (100%) who underwent computed tomography. CONCLUSIONS: In this series, African American patients were more likely to be diagnosed as having uveitic sarcoidosis and to present with uveitis if they were younger than 50 years. White patients were more likely to present when they were older than 50 years. A clinical picture that included granulomatous anterior segment inflammation was more common in African American patients. The use of serum markers (angiotensin-converting enzyme and lysozyme) positively identified more patients with biopsy-proven sarcoidosis when used in combination with appropriate chest imaging.
