Point-of-care ultrasound associated with shorter length of stay than computed tomography for renal colic.

BACKGROUND: Despite similar diagnostic effectiveness for renal colic, computed tomography (CT) is more resource intensive than point-of-care ultrasound (PoCUS). We sought to compare Emergency Department (ED) length of stay (LOS) among patients with renal colic according to imaging modality utilized. We secondarily compared rates of infection, return ED visits, missed significant pathology, and urologic intervention. METHODS: This was a 12-month (1/1/22-12/31/22) multi-site retrospective cohort study of all patients diagnosed with renal colic who presented to the ED on days when at least one patient had a billable renal PoCUS examination performed. Patients with a history of genitourinary malignancy, pregnancy, renal transplant, hemodialysis, single kidney, prior visit for renal colic in the previous 30 days, or an incomplete workup were excluded. Median ED LOS was compared using a Wilcoxon rank sum test, and the 95% confidence limits for the difference between medians was calculated. Secondary outcomes were compared using a Fisher's Exact test. RESULTS: Of 415 patients screened, 325 were included for analysis: 150 had CT alone, 80 had PoCUS alone, 54 had PoCUS plus CT, and 41 had neither. Median LOS for PoCUS alone was 75.0 (95% CI 39.3-110.7) minutes shorter than CT alone (231.5 vs. 307.0 min, p < 0.0001). Similar rates of infection, return visits, and missed pathology occurred across all groups (p > 0.10). Urologic interventions were higher in the PoCUS plus CT (25.9%) group compared to CT alone (7.3%), PoCUS alone (2.5%), and neither (7.3%), p < 0.0001. CONCLUSION: Among patients with renal colic, PoCUS was associated with shorter ED LOS compared to CT, without differences in infection rates, return visits, or missed pathology. Patients with PoCUS plus CT had a higher rate of urologic interventions, suggesting PoCUS may have a role in identifying patients who would most benefit from CT.

The Shift: COVID-19-Associated Deaths are Now Trending Lower Among Blacks and Hispanics Compared to Whites.

BACKGROUND: Throughout the coronavirus (COVID-19) pandemic, research revealed people of color were more likely to be infected, have severe illness, and die due to the virus. However, some areas in the USA are now reporting a new shift; lower Black and Hispanic COVID-19 mortality rates compared to their White counterparts. Research indicates that this shift is the result of COVID-19's impact on disparities by race. In this paper, we analyze death data to determine if the new shift has occurred locally. Specifically, we examined COVID-19 prevalence and related death data in Connecticut by comparing race/ethnicity through two periods of time: one before and one after the first case of the Omicron variant of COVID-19. METHODS: This cross-sectional epidemiological analysis to examine cases and deaths by racial/ethnic status utilizes Connecticut data from March 2020 to February 2022. The following assumption is applied: expected pre-Omicron cases and deaths from March 5, 2020 to November 27, 2021 are equal to the number of cases and deaths during Omicron cases and deaths from November 28, 2021 to February 17, 2022. Race/ethnicity are operationalized as non-Hispanic White, non-Hispanic Black, and Hispanic. RESULTS: Pre-Omicron (March 5, 2020 to November 27, 2021) compared to the monthly aged adjusted COVID-19 case rate for Whites (394/10,000 populations), Blacks had a higher rate (501/10,000 populations), and Hispanics had the highest (585/10,000 populations). During the Omicron period (November 28 to February 17, 2022), significant changes in COVID-19 case rates were observed in all three ethnic groups, but the biggest changes were observed in Hispanics, followed by Blacks, and then Whites. The rate ratios further showed a remarkable reduction of 47% in case rates (from 1.0 pre-Omicron and from 1.47 during Omicron, p < 0.0001) for Hispanics, when compared to that of Whites. While Blacks showed a significant, smaller reduction of 5% in case rates (from 1.27 pre-Omicron and from 1.22 during the Omicron, p < 0.001) when compared to Whites. Regarding COVID-19-related mortality, the racial differences were similar. CONCLUSIONS AND RELEVANCE: By examining Connecticut's COVID-19 death and case data, this study identified the new shift that occurred locally. The current shift may be anchored in the evolution of the COVID-19 virus, public health guidelines/policies, and the degree to which populations have complied with public health recommendations.

Minutes matter: Time it takes to perform point-of-care ultrasound.

Background: While point-of-care ultrasound (PoCUS) is a safe, versatile tool that can improve patient care, the perceived time investment needed to incorporate PoCUS into clinical care is cited as a barrier to performance. We sought to determine the time it takes to perform a PoCUS examination and whether this time was influenced by training level and prior ultrasound experience. Methods: This was a retrospective study looking at time stamps of all emergency medicine (EM) provider-performed PoCUS examinations during clinical shifts from August 10, 2019, to June 7, 2022, at a suburban academic emergency department that is the site for a 3-year EM residency. Our workflow is order-based; when PoCUS is ordered, that patient's information populates the ultrasound machine worklist. Selecting the patient's name from the worklist generates a time-stamped patient information page (PIP). We defined the PIP time stamp as the start of the PoCUS examination. The duration of one PoCUS examination was defined as the time of the last image acquired minus the time of the PIP. General estimating equations were used to estimate differences between training level and between prior scan status using an exchangeable correlation and Tukey adjusted pairwise comparisons. A two-tailed chi-square analysis was used for comparing accuracy according to training level. Results: Of 4187 PoCUS examinations abstracted, 2144 met study criteria. The median (IQR) time spent per examination was 6.0 (3-9) min. First-year residents took the longest to perform PoCUS among all providers (p < 0.0001). Residents with fewer than 250 prior scans took longer than residents with 501-800 (p = 0.0002) and >800 (p = 0.0013). Resident accuracy was not significantly different according to training level. Conclusions: Overall median time to perform PoCUS was 6.0 min. EM residents became more efficient in performing PoCUS as they advanced from first- to third-year, without compromising accuracy.

Disclosure of Complementary and Alternative Medicine Use Among Older Adults: A Cross-Sectional Study.

Background: Although use of complementary and alternative medicine (CAM) is rising among older adults, many do not discuss these healthcare practices with their primary care practitioners (PCPs). This study sought to determine the prevalence of CAM use and to identify factors associated with CAM disclosure among patients ages 65 and older. Methods: Participants completed an anonymous survey, which evaluated their CAM use over the past year and disclosure of CAM to a PCP. Additional questions queried demographics, patient health, and relationships with one's PCP. Analyses included descriptive statistics, chi-square tests and logistic regression. Results: One hundred seventy-three participants answered surveys. Sixty percent reported use of at least one form of CAM in the past year. Among those using CAM, 64.4% disclosed use to their PCP. Patients disclosed supplements/herbal products and naturopathy/homeopathy/acupuncture at a higher rate than body work techniques and mind-body practices (71.9% and 66.7% vs. 48% and 50%). The only factor significantly associated with disclosure was trust in one's PCP (odds ratio = 2.97; confidence interval = 1.01-8.73). Conclusions: Clinicians may improve CAM disclosure rates in older adults by inquiring about all types of CAM and continuing to invest in their patient relationships, specifically by building trust.

Combination of naproxen and a chemically-stable eicosapentaenoic acid analog provide additive tumor protection in Pirc rats.

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Patients with the genetic disorder Familial Adenomatous Polyposis (FAP) develop hundreds to thousands of polyps that unless removed by prophylactic colectomy will progress to CRC at an early age. Nonsteroidal anti-inflammatory drugs (NSAIDs) and the ω-3 polyunsaturated fatty acid (PUFA) eicosapentaenoic acid (EPA), have been evaluated for their chemopreventive potential in delaying CRC onset in high-risk patients. In our study, we determined whether the NSAID, naproxen, alone or in combination with a chemically-stable EPA analog (TP-252), affects tumor formation in the ApcPirc rat model. When compared to control diet, animals fed naproxen or HD TP-252 had 66% and 82% fewer tumors, respectively. However, animals fed a combination of naproxen and HD TP-252, exhibited a 95% reduction in tumor formation and a 98% reduction in tumor volume, respectively. To elucidate potential mechanisms of tumor protection, a comprehensive, targeted lipidomic analysis was performed on colonic mucosa to determine changes in eicosanoid metabolism. Animals receiving TP-252 alone or in combination with naproxen had significantly reduced mucosal levels of proinflammatory ω-6 eicosanoids (PGE2 , 5-HETE and 14,15-DiHETrE), along with a simultaneous increase in anti-inflammatory EPA-derived ω-3 eicosanoids. A comprehensive lipidomic analysis also uncovered several potential pharmacodynamic (PD) lipid biomarkers, including resolvin E2, 9-HEPE, 12-HEPE and 18-HEPE, that were significantly correlated with tumor protection. Further studies with this drug combination should be focused on dose optimization and the role of EPA-derived lipid mediators in CRC initiation and progression.

Association of Race, Ethnicity, Education, and Neighborhood Context With Dementia Prevalence and Cognitive Impairment Severity Among Older Adults Receiving Medicaid-Funded Home and Community-Based Services.

OBJECTIVE: While racial, ethnic, and socioeconomic group disparities in cognitive impairment and dementia prevalence are well-documented among community-dwelling older adults, little is known about these disparity trends among older adults receiving Medicaid-funded home- and community-based services (HCBS) in lieu of nursing home admission. The authors determined how dementia prevalence and cognitive impairment severity compare by race, ethnicity, educational attainment, and neighborhood context in a Medicaid HCBS population. DESIGN/SETTING: A cross-sectional study in Connecticut. PARTICIPANTS: Adults age ≥65 in the HCBS program, January-March 2019 (N = 3,520). MEASUREMENTS: The data source was Connecticut's HCBS program Universal Assessment tool. The authors employed two outcomes: Cognitive Performance Scale (CPS2), a 9-point measure ranging from cognitively intact-very severe impairment; and presence or not of either diagnosed dementia or CPS2 score ≥4 (major impairment). Neighborhood context was measured using the Social Vulnerability Index (SVI). RESULTS: Cohort characteristics: 75.7% female; mean(SD) age = 79.1(8.2); Non-Hispanic White = 47.8%; Hispanic = 33.6%; Non-Hispanic Black = 15.9%. Covariate-adjusted multivariate analyses revealed no dementia/major impairment prevalence differences among White, Black, and Hispanic individuals, but impairment severity was greater among Hispanic participants (b = 0.22; p = 0.02). People with more than HS education had less severe impairment (b = -0.12; p <0.001) and lower likelihood of dementia/major impairment (AOR = 0.61; p <0.001). Dementia/major impairment likelihood and impairment severity were greater in less socially vulnerable neighborhoods. CONCLUSION: Racial and ethnic group differences in cognitive impairment are less pronounced in Medicaid-funded HCBS cohorts than in other community-dwelling older adult cohorts. SVI results suggest that, among other possible explanations, older adults with dementia may move to lower social vulnerability neighborhoods where supportive family members reside.

Effects of Longitudinal Changes in Neuroticism and Stress on Cognitive Decline.

OBJECTIVE: The relationships among depression, personality factors, stress, and cognitive decline in the elderly are complex. Depressed elders score higher in neuroticism than nondepressed older individuals. Independently, the presence of neuroticism and the number of stressful life events are each associated with worsening cognitive decline in depressed older adults. Yet little is known about combined effects of changes in neuroticism and changes in stress on cognitive decline among older depressed adults. DESIGN: Longitudinal observational study. SETTING: Academic Health Center. PARTICIPANTS: The authors examined 62 participants in the Neurobiology of Late-life depression (NBOLD) study to test the hypothesis that, compared with older depressed subjects who experience improved neuroticism and lower psychosocial stressors over time, those with worsening neuroticism and greater psychosocial stressors will demonstrate more cognitive decline. MEASUREMENTS: The authors measured neuroticism using the NEO-Personality Inventory-Revised at baseline and 1 year. Study psychiatrists measured depression using the Montgomery-Ǻsberg Depression Rating Scale. At annual assessments, subjects reported the number of psychosocial stressors in the prior year and completed a neuropsychological evaluation. Participants completed a detailed neuropsychological battery at baseline and annually over 3 years. The battery included a test of delayed story memory (Logical Memory-2 or LMII). The outcome 3-year change in cognitive scores was regressed against 3-year change scores of neuroticism and number of psychosocial stressors, plus their interaction, while adjusting for sex, age, race, education, baseline cognitive score, and 3-year change in MADRS score as covariates. RESULTS: In multivariable linear regression analysis with the above covariates, the interaction effect of 3-year change in Total Neuroticism score and 3-year change in Total Stressors on change in LMII performance was statistically significant (B = -0.080[95%CL: -0.145 to -0.015], T = -2.48, df = 52, p = 0.017). Further exploration of this finding showed that 1) when total stressors increased by 2 or more over 3 years, LMII change was inversely associated with neuroticism change; and 2) when neuroticism improved less, LMII change score was inversely associated with total stressor change. There were no other significant interactions between stress and neuroticism on cognition. CONCLUSION: Our findings document the importance of tracking change in neuroticism and monitoring psychosocial stress over the long-term course of treatment in geriatric depression. Both factors exert important combined effects on memory over time. Future studies in larger samples are needed to confirm our results and to extend them to examine both cognitive change and development of dementia.

Genipin does not reduce the initiation or propagation of microcracks in collagen networks of cartilage.

Objective: We recently initiated microcracks, i.e. micron-scale cracks in the collagen networks of cartilage, using both single low-energy impacts and unconfined, cyclic compressions. We also tracked the propagation of microcracks after cyclic compressions simulating 12,000 walking strides. In this study, we aimed to determine the effect of one or more genipin treatments on: (1) the initiation of microcracks under mechanical impacts and (2) the subsequent propagation of microcracks under cyclic, unconfined compression. We hypothesized that treatments with genipin would improve the resistance of cartilage to microdamage, specifically reducing both the initiation of microcracks under impact loading and the propagation of microcracks under cyclic compression. Design: We tested 49 full-thickness, cylindrical osteochondral specimens. We incorporated one or two doses of genipin in between mechanical treatments, i.e. single low-energy mechanical impacts to initiate microcracks and unconfined, cyclic compressions to propagate microcracks. We also imaged specimens using second harmonic generation confocal microscopy, and analyzed the resulting images to quantify changes in morphologies (length, width, and depth) and orientations of microcracks. Finally, we used separate mixed-regression modeling to evaluate the effects of genipin treatments on mechanically induced microcracks. Results: Specimens treated with genipin presented significantly longer and marginally deeper microcracks after mechanical impacts. Two doses of genipin caused significantly longer and wider microcracks under propagation verses one dose. Conclusions: Our results do not support our hypothesis: unfortunately treatments with genipin, and the resulting mechanisms of cross-linking, do not provide resistance to microdamage, quantified as the initiation and propagation of microcracks.

Associations of the skin, oral and gut microbiome with aging, frailty and infection risk reservoirs in older adults.

Older adults represent a vulnerable population with elevated risk for numerous morbidities. To explore the association of the microbiome with aging and age-related susceptibilities including frailty and infectious disease risk, we conducted a longitudinal study of the skin, oral, and gut microbiota in 47 community- or skilled nursing facility-dwelling older adults vs. younger adults. We found that microbiome changes were not associated with chronological age so much as frailty: we identified prominent changes in microbiome features associated with susceptibility to pathogen colonization and disease risk, including diversity, stability, heterogeneity, and biogeographic determinism, which were moreover associated with a loss of Cutibacterium (C.) acnes in the skin microbiome. Strikingly, the skin microbiota were also the primary reservoir for antimicrobial resistance, clinically important pathobionts, and nosocomial strains, suggesting a potential role particularly for the skin microbiome in disease risk and dissemination of multidrug resistant pathogens.

A calibrated cell-based functional assay to aid classification of MLH1 DNA mismatch repair gene variants.

Functional assays provide important evidence for classifying the disease significance of germline variants in DNA mismatch repair genes. Numerous laboratories, including our own, have developed functional assays to study mismatch repair gene variants. However, previous assays are limited due to the model system employed, the manner of gene expression, or the environment in which function is assessed. Here, we developed a human cell-based approach for testing the function of variants of uncertain significance (VUS) in the MLH1 gene. Using clustered regularly interspaced short palindromic repeats gene editing, we knocked in MLH1 VUS into the endogenous MLH1 loci in human embryonic stem cells. We examined their impact on RNA and protein, including their ability to prevent microsatellite instability and instigate a DNA damage response. A statistical clustering analysis determined the range of functions associated with known pathogenic or benign variants, and linear regression was performed using existing odds in favor of pathogenicity scores for these control variants to calibrate our functional assay results. By converting the functional outputs into a single odds in favor of pathogenicity score, variant classification expert panels can use these results to readily reassess these VUS. Ultimately, this information will guide proper diagnosis and disease management for suspected Lynch syndrome patients.

Matrix Metalloproteinase-14 as an Instigator of Fibrosis in Human Pterygium and Its Pharmacological Intervention.

There exists a paucity of information on the pathogenesis of pterygium, a benign ocular tumor that scars the cornea and can lead to vision loss. The main recourse for pterygium is surgery; however, recurrence is observed. Matrix metalloproteinases (MMPs) are involved in the pathology of pterygium. The determination of the specific MMP involved among the 24 human enzymes has not been established due to challenges in MMP profiling. We used an affinity resin that binds specifically to the active forms of MMPs in the complex mixture of the cellular proteome. The proteomics analysis identified active MMP-14 and three related metalloproteinases, ADAM9, ADAM10, and ADAM17, in human pterygia. Inhibition of MMP-14 with the small-molecule inhibitor (R)-ND-336 was assessed in cell migration and collagen contraction assays. (R)-ND-336 attenuated human conjunctiva fibroblast migration and mitigated collagen contraction, both activities required for the formation of pterygium. (R)-ND-336 holds the promise of a therapeutic recourse for pterygium as an orphan disease.

Pregnancy outcomes after frozen-thawed embryo transfer using letrozole ovulation induction, natural, or programmed cycles.

OBJECTIVE: To evaluate and compare pregnancy outcomes between letrozole ovulation induction, natural, and programmed frozen-thawed embryo transfer (FET) cycles in a population based in the United States. DESIGN: Retrospective cohort study. SETTING: Single university-affiliated infertility practice. PATIENT(S): A total of 3,148 FET cycles consisting of patients aged ≤45 years transferring blastocysts that were created from autologous oocytes between January 2015 and July 2021. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was the ongoing pregnancy rate (OPR) or live birth rate (LBR). The secondary outcomes included clinical pregnancy and clinical loss rates (CLRs). RESULT(S): The OPR/LBR was higher among letrozole FETs than among programmed FETs (adjusted risk ratio [aRR] 1.11, 95% confidence interval [CI] 1.02-1.21) but comparable to natural FETs (aRR 1.05, 95% CI 0.96-1.14). The OPR/LBR was comparable between natural and programmed FETs (aRR 1.06, 95% CI 0.99-1.13). The CLR was lower in the natural FET group than in the programmed FET group (aRR 0.62, 95% CI 0.46-0.84). There were no differences in CLRs between letrozole and programmed FETs and between letrozole and natural FETs. Among ovulatory women, the OPR/LBR among letrozole FETs was higher than that among programmed FETs (aRR 1.16, 95% CI 1.05-1.28). The CLR among ovulatory women was significantly lower in both letrozole FETs (aRR 0.44, 95% CI 0.22-0.87) and natural FETs (aRR 0.59, 95% CI 0.43-0.80) than in programmed FETs. Among anovulatory women, the OPR/LBR in the letrozole FET group was similar to that in the programmed FET group (aRR 0.95, 95% CI 0.79-1.13). CONCLUSION(S): Letrozole and natural FET clinical outcomes were improved compared with programmed FET outcomes.

Cognitive Frailty is Associated With Elevated Proinflammatory Markers and a Higher Risk of Mortality.

BACKGROUND: Cognitive impairment and physical frailty are common among older adults and associated with a higher likelihood of adverse health outcomes. These two conditions frequently coexist in the same individual as cognitive frailty, yet few studies have examined the impact of such comorbidity on clinical outcomes or underlying biological mechanisms. METHODS: A total of 1,340 older adults (age ≥60 years old) from the Bambui Cohort Study of Ageing, with a total follow-up of 10 years, were included in this study. Frailty was defined by the accumulation of deficit framework and cognitive impairment based on scores on the MMSE less than 22. In addition, serum IL-6 levels were measured by cytometric bead array assay. RESULTS: Individuals classified with cognitive frailty had significantly higher serum IL-6 levels compared to the robust, cognitively unimpaired group. Those with cognitive frailty (aOR = 1.97 [1.18-3.27] and prefrailty and cognitive impairment (aOR = 1.83 [1.24-2.69]) had the highest mortality risk over 10 years of follow-up. Higher IL-6 levels were also independently associated with a higher mortality rate (aOR = 1.37 [1.23-1.54]). CONCLUSION: Our study shows that cognitive Frailty indicates a vulnerability state and of increasing mortality risk. Our findings also suggested that proinflammatory abnormalities can be viewed as a central phenomenon underlying common age-related problems (e.g., cognitive impairment and Frailty) and outcomes (e.g., mortality).

Association of 1-year change in neuroticism and 3-year change in cognitive performance among older depressed adults.

OBJECTIVES: The relationships among depression, personality factors, and cognitive decline in the elderly are complex. Depressed elders score higher in neuroticism than nondepressed older individuals. Presence of neuroticism worsens cognitive decline in depressed older adults. Yet little is known about changes in neuroticism among older adults being treated for depression and the impact of these changes on cognitive decline. DESIGN: Longitudinal observational study. SETTING: Academic Health Center. PARTICIPANTS: We examined 68 participants in the neurobiology of late-life depression (LLD) study to test the hypothesis that older depressed subjects with more improvement in neuroticism would experience less cognitive decline compared with those with less change in neuroticism. MEASUREMENTS: We measured neuroticism using the NEO-Personality Inventory-Revised at baseline and 1 year. Study psychiatrists measured depression using the Montgomery-Åsberg depression rating scale (MADRS). Global cognitive performance was measured using the Consortium to Establish a Registry for Alzheimer's disease (CERAD) battery at baseline and annually over 3 years. Regression models of 1-year change in neuroticism and 3-year change in CERAD included sex, age, race, education, and 1-year change in MADRS score as covariates. RESULTS: We found that among older adults, 1-year change in neuroticism was inversely associated with 3-year change in CERAD total score. CONCLUSIONS: Our findings challenge the notion of longitudinal stability of measures of personality, especially among older depressed individuals. They highlight the importance of repeated personality assessment, especially of neuroticism, in the management of LLD. Future studies in larger samples followed for longer periods are needed to confirm our results and to extend them to examine both cognitive change and development of dementia.

Evaluating Cognitive/Emotional and Behavioral Mediators of Oral Health Outcomes in Vulnerable Older Adults.

Inconsistent outcomes of oral hygiene interventions require testable theories combining cognitive and behavioral domains to guide intervention and improve results. This article evaluates the integrated model as a cognitive-behavioral approach to improve oral health clinical outcomes in ethnically diverse low-income older adults. Baseline data from a clinical trial utilizing the integrative model (IM) model evaluated predictors of gingival index (GI) and plaque score (PS). Individual logistic regression was performed for all predictors in relation to GI and PS. Multiple logistic regression was performed with significant predictors of GI and PS only. Greater locus of control and more brushing predicted lower GI; greater locus of control predicted lower PS. Both cognitive and behavioral domains impact GI, requiring more prolonged effort for improvement while locus of control, a cognitive variable, predicts PS, immediately improved by daily brushing/flossing. A streamlined IM including locus of control and tooth brushing should improve oral hygiene of low-income older adults.

Fentanyl, Heroin, and Cocaine Overdose Fatalities are Shifting to the Black Community: An Analysis of the State of Connecticut.

BACKGROUND: Historically, Blacks and Hispanics have had lower opioid-involved overdose death rates in Connecticut (CT). We examined if a shift has taken place where rates of Black fatal overdoses have now surpassed Whites in the state. METHODS: Drug overdose fatality rates were calculated by number of deaths per year per 100,000 population from 2012 to 2019 in Connecticut. Measures were by race (White, Hispanic, Black, and Asian or Pacific Islander), age groups, and types of drugs, including fentanyl, heroin, cocaine, and other opioids. Poisson regression was used to test the interactions (race × age); joinpoint regression analysis was used to evaluate trend lines of fatality rate by racial/ethnic group within each age group with a significance level of p < 0.05. RESULTS: Drug overdose fatality rates in CT from 2012 to 2019 showed a significant increase for all races combined, estimated 3.6 deaths per 100,000 population per year. For Whites, overdose deaths were 4.6 per year from 2012 to 2017 with no change from 2017 to 2019. The overdose fatality rate for Hispanics was 3.0 and for Asian or Pacific Islanders 0.6 per year from 2012 to 2019. For Blacks, the death rates were statistically flat between 2012 and 2014; however, from 2015 to 2019, this group saw the largest average increase of 6.0 overdose deaths per 100,000 population each year. By 2019, the overdose fatality rate was higher in Blacks than in Whites, (39 vs. 38 per 100,000, respectively). Further, Blacks ages 50 years and over reported the highest overdose fatality rates among all race/age groups, an increase of 8.5 deaths per 100,000 population since 2014. CONCLUSIONS AND RELEVANCE: Connecticut is a microcosm of the opioid overdose trend in the New England region of our country. The majority of overdose deaths in CT involved illicit drugs, fentanyl, heroin, and cocaine, rather than prescription drugs. Blacks 50-years-old and over showed the fastest growing overdose death rates. Opioid deaths are now shifting to the Black community, creating an urgent public health crisis.

Changes in COVID-19-Associated Deaths During a Year Among Blacks and Hispanics Compared to Whites in the State of Connecticut.

BACKGROUND: With recent COVID-19 vaccination rates relatively high in the USA, the USA still maintains the most documented cases globally,[1] even though COVID-19 cases, hospitalization, and mortality have been declining. However, the health burden has been largely felt in communities involving racial and ethnic minorities. Thus, in order to provide a clearer picture of what is happening in Black, Indigenous, and people of color communities, we examined the racial/ethnic differences of monthly COVID-19 deaths in Connecticut. METHODS: This is an epidemiological study analyzing mortality data from March 1, 2020, to February 28, 2021, obtained from the Connecticut State Department of Public Health. The data include cause of death (COVID-19 death identified by ICD-10 code U071), race/ethnicity (non-Hispanic White (White), non-Hispanic Black (Black), and Hispanic), sex, and age. Both crude and age-adjusted rates were reported by racial/ethnic groups. To compare age-adjusted rates between racial groups, with estimated age-adjusted death counts as outcomes, between-racial group rate ratios, 95% confidence intervals, and p values significant at < 0.05 were derived from the Poisson regression model. RESULTS: From March 2020 to May 2020 (wave 1) of COVID-19 cases, the COVID-19-related mortality rates were the highest for all three race groups (Whites, Blacks, and Hispanics) with statistical group differences (p < 0.05). Blacks had the highest rates of deaths followed by Hispanics and then Whites. Further, more Whites died in a nursing home when compared to Blacks and Hispanics. From June 2010 to October 2020 (wave 2), COVID-19 mortality declined significantly for all three race groups with no statistical differences between groups. COVID-19 deaths in nursing homes declined for all three racial/ethnic groups. From November 2020 to February 2021 (wave 3), COVID-19 mortality rates were significantly higher compared to wave 2 but lower than wave 1 for all three race groups. The mortality rates for Blacks and Hispanics were higher than Whites. Hispanics had the highest rates of deaths, followed by Blacks, and then Whites (p < 0.05). Whites showed the lowest mortality rates among all three racial/ethnic groups. CONCLUSIONS: In summary, COVID-19 health disparities among Black and Hispanic populations were evident in this study. Blacks and Hispanics had significantly higher mortality rates when compared to Whites. Blacks had the highest mortality rates during wave 1, and in wave 3, Hispanics has the highest mortality rates. Our data are important because they show monthly COVID-19 deaths data by race. Data reported this way gives a better and more accurate understanding of what is really happening in Black, Indigenous, and people of color populations.

Does sequencing matter? A cross-over randomized trial to evaluate a bi-level community-based intervention to improve oral hygiene among vulnerable adults.

OBJECTIVES: To evaluate whether the cumulative effect of an individual-level intervention followed by a building-level intervention, both based on Fishbein's Integrated Model of Behavior Change, has a better effect on oral hygiene clinical outcomes than the sequence of the building-level intervention followed by the individual-level intervention; to determine the added effect of each intervention on the other; to identify the psychosocial mechanisms that might explain the differences. METHODS: Six low-income senior housing complexes were enrolled in the study, and participants were recruited from these buildings. Buildings were randomly assigned to receive either the individual counselling intervention first followed by the building-level intervention, or the building-level intervention first followed by the individual intervention. Participants were assessed for gingival inflammation using the gingival index (GI) and plaque scores (PS) at T0, prior to the interventions, T1, about one month after each intervention and T2, about a month after the interventions switched and were completed. Data were collected on background moderators and cognitive/emotional/behavioural mediators in surveys administered at T0, T1 and T2. General linear mixed models were used to assess changes over time by condition and to analyse the effects of moderators and mediators over time. RESULTS: Three hundred and thirty-one people completed T0; 306 completed T1 assessments (92.4% retention rate) and 285 completed T2 assessments (86.1% retention rate). All participants improved on GI and PS at T1 and T2 compared to T0. Those in the individual-level intervention condition improved more than those in the building-level condition. Those who were in the building-level intervention followed by the individual intervention continued to improve on GI from T1 to T2. Those in the individual-based intervention followed by the building intervention did not improve significantly from T1 to T2 but remained about the same. For PS, neither group improved significantly from T1 to T2. Several cognitive/behavioural variables significantly affected improvements in GI and PS. CONCLUSIONS: Both interventions were successful in improving GI and PS. The building-level intervention did not provide much additional benefit when it followed the individual intervention although it may have had a sustaining effect. The findings on the cognitive/emotional/behavioural variables support the importance of these factors and should be considered when implementing oral hygiene interventions.

Black race associated with lower live birth rate in frozen-thawed blastocyst transfer cycles: an analysis of 7,002 Society for Assisted Reproductive Technology frozen-thawed blastocyst transfer cycles.

OBJECTIVE: To evaluate if racial/ethnic differences in pregnancy outcomes persisted in frozen-thawed embryo transfer (FET) cycles on a national level. DESIGN: Retrospective cohort study. SETTING: Clinic-based data. PATIENT(S): A total of 189,000 Society for Assisted Reproductive Technology FET cycles from 2014-2016 were screened, of which 12,000 cycles had available fresh cycle linkage information and ultimately, because of missing data, 7,002 FET cycles were included. Cycles were stratified by race (White, Black, Asian, and Hispanic). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was live birth rate. Secondary outcomes were implantation rate, clinical pregnancy rate, multiple pregnancy rate, and clinical loss rate (CLR). RESULT(S): Live birth rate was significantly lower in the Black vs. White and Asian, but not Hispanic group. Implantation rate was also significantly lower and CLR higher in the Black group compared with all other groups (all P<.01). Black women had a lower risk of live birth (adjusted risk ratio, 0.82; 95% confidence interval [CI], 0.73-0.92) and a higher risk of clinical loss (adjusted risk ratio, 1.59; 95% CI, 1.28-1.99) compared with White women. There was no significant difference between groups in clinical pregnancy rate or multiple pregnancy rate. When the analysis was limited to preimplantation genetic testing FET cycles, there remained a significantly lower implantation rate in the Black group compared with all other groups (all P<.01). CONCLUSION(S): Black race remains an independent predictor of reduced live birth rate in FET cycles, likely because of higher CLR.
