Pandemic Meets Endemic: The Role of Social Inequalities and Failing Public Health Policies as Drivers of Disparities in COVID-19 Mortality among White, Black, and Hispanic Communities in the United States of America.

The COVID-19 pandemic placed the United States of America (U.S.) under enormous strain, leaving it with higher deaths during the first wave of the outbreak compared to all other advanced economies. Blacks and Hispanics were among those hardest hit by the virus-a fact attributed to enduring problems related to the social determinants of health adversely affecting Communities of Color (CoC). In this study, we ask which distinct factors relating to policy stringency and community vulnerability influenced COVID-19 mortality among Whites, Blacks, and Hispanics during the first year of the pandemic. To address this question, we utilized a mix of correlational and regression analyses. Findings point to the highly divergent impact of public policy and vulnerability on COVID-19 mortality. Specifically, we observed that state-led measures aimed at controlling the spread of the virus only improved mortality for Whites. However, pre-existing social determinants of health (i.e., population density, epidemiological and healthcare system factors) played a significant role in determining COVID-19 outcomes for CoC, even in the face of stringent containment measures by states. This suggests that state-led policy to address present and/or future public health crises need to account for the particular nature of vulnerability affecting Blacks and Hispanics in the U.S.

Analysis of end-user satisfaction with electronic health records in college/university healthcare.

ObjectiveTo determine levels of Electronic Health Record (EHR) satisfaction in order to add to the body of knowledge and assist professionals in the college/university health field with system/vendor selection. Methods: Nine health centers, all within highly selective colleges and universities, participated in this benchmarking study. Multidisciplinary staff (n = 316) received an anonymous 32-item survey to assess levels of agreement/satisfaction on statements pertaining to their EHR's functionality. Results: The EHRs most commonly used were Point and Click, Medicat, Allscripts, and EPIC. There was considerable variation on levels of user satisfaction/agreement within features among the EHR systems, but differences were not statistically significant. Conclusion: No systems emerged as clear "winners" in terms of user satisfaction. Features were identified within systems that can be leveraged to meet specific care delivery and quality reporting needs among college/university health professionals, and could be considered in the use of EHRs by health services.

Increasing influenza immunization rates among healthcare providers in an ambulatory-based, University Healthcare Setting☆.

OBJECTIVE: Despite its 'best practice' status as an intervention to combat healthcare-related influenza, many healthcare personnel (HCP) do not seek vaccinations themselves. The objective of this study was to achieve the Healthy People [HP] 2020's influenza vaccination goal of 90% among our HCP. DESIGN: The study utilized the model for improvement, consisting of Plan-Do-Study-Act (PDSA) cycles. Each influenza season served as a PDSA cycle until the HP 2020 vaccination goal was achieved. The quality improvement (QI) study was conducted over four influenza seasons (i.e. 2014-15; 2015-16; 2016-17 and 2017-18). SETTING: The study's setting was an ambulatory-based, university health center within a suburban university located in central New Jersey. PARTICIPANTS: Adapting the National Vaccine Advisory Committee's definition of HCP, clinical and non-clinical staff members (n = 110) participated in the QI-study. INTERVENTIONS: QI-interventions were centered on staff education/outreach, improved accessibility to influenza vaccines and frequent communication to staff over several PDSA cycles. MAIN OUTCOME & RESULTS: The QI-interventions significantly increased our overall vaccination coverage on our influenza vaccination status survey from 70.2% (2011-14 influenza seasons; n = 102) to 84.9% (2014-15 influenza season; n = 93) in PDSA 1, and 91.1% (2015-16 influenza season; n = 90) in PDSA cycle 2 (χ2 = 309.53, P < 0.001). Vaccination rates remained above the 90% performance goal during our quality control/assurance measuring periods (i.e. the 2016-18 influenza seasons). CONCLUSIONS: This study demonstrates that influenza vaccination coverage can significantly improve among HCP through the application of concurrent and multifaceted QI-interventions.

Interdisciplinary communication in inpatient rehabilitation facility: evidence of under-documentation of spatial neglect after stroke.

PURPOSE: Spatial neglect commonly occurs after stroke and predicts poor rehabilitation outcomes. However, this disorder is under-recognized in clinical practices, which may result from the failure to document its presence. This study aimed to identify the predictors for documentation of spatial neglect in inpatient rehabilitation facilities. METHOD: We performed a comprehensive chart review to investigate whether the presence of spatial neglect was documented in 74 neglect patients' clinical notes recorded by physicians, nurses, or occupational therapists (OTs), or in team conference notes. Independent variables included neglect severity, length of stay, Functional Independence Measure at admission and discharge. RESULTS: Of the 74 neglect patients, 75.7% were documented by OTs, 63.5% by physicians, and 17.6% by nurses. Although 93.2% of neglect patients were recognized by at least one clinician group, only 31.1% were discussed in multidisciplinary team conferences. Neglect patients who were documented by physicians were more likely to be documented in team conferences. While no factors predicted whether a neglect patient would be documented by nurses or OTs, we found significant predictors for neglect documentation in physician and team conference notes. The odds of being documented by physicians were increasingly greater with poorer efficiency of cognitive rehabilitation (odds ratio = 0.70). The odds of being discussed in team conferences were increasingly greater with more severe neglect (odds ratio = 0.98), and with longer stay in hospitalization (odds ratio = 1.06). CONCLUSIONS: Multidisciplinary care may not involve as much interdisciplinary communication as needed to document important disease states. Stroke rehabilitation professionals should be able to recognize spatial neglect independently and document it consistently.

Left-sided brain injury associated with more hospital-acquired infections during inpatient rehabilitation.

OBJECTIVE: To test the hypothesis that a left-dominant brain immune network (LD-BIN) might affect the occurrence of infection during inpatient rehabilitation of stroke and traumatic brain injury (TBI). DESIGN: A retrospective analysis was performed on electronic medical records between January 2009 and December 2010. All patients with left- or right-sided stroke or TBI were included into the study. The LD-BIN hypothesis was tested by comparing HAI rates depending on whether patients had left- or right-sided brain lesions. SETTING: A large inpatient rehabilitation hospital. PARTICIPANTS: Among the patients (N=2236) with stroke or TBI who had either a left- or right-sided brain lesion, 163 patients were identified with HAIs. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Frequency of HAIs. RESULTS: In the 163 patients identified with HAIs with a diagnosis of stroke or TBI, chi-square analysis revealed a significantly higher proportion of HAIs among patients with left-sided (n=98; 60.1%) relative to right-sided (n=65; 39.9%) brain injuries (χ(2)=6.68, P<.01). These effects could not be attributed to either clinical or demographic factors. CONCLUSIONS: Our findings are consistent with the hypothesis that an LD-BIN may mediate vulnerability to infection during rehabilitation of patients with stroke or TBI. Further translational research investigating novel means of managing patients based on brain lesion location, and modulating the LD-BIN via behavioral and physiologic interventions, may result in neuroscience-based methods to improve infection resistance in brain-injured patients.

Differential role of dopamine in emotional attention and memory: evidence from Parkinson's disease.

Consistent with the hypothesis that dopamine is implicated in the processing of salient stimuli relevant to the modification of various behavioral responses, Parkinson's disease is associated with emotional blunting. To address the hypothesis that emotional attention and memory are modulated by dopaminergic neurotransmission in Parkinson's disease, we assessed 15 nondemented patients with Parkinson's disease while on and off dopaminergic medication and 15 age-matched healthy controls. Visual stimuli were presented, and recognition was used to assess emotional memory. Response latency was used as a measure of emotional attention modulation. Stimuli were varied based on valence (pleasant, neutral, and unpleasant) and arousal (high and low) dimensions. Controls had significantly better memory for positive than negative stimuli, whereas patients with Parkinson's disease tested off medication had significantly better memory for negative than positive items. This negativity bias was lost when they were tested while on dopaminergic medication. Reaction times in patients with Parkinson's disease off medication were longer than in healthy controls and, paradoxically, were even longer when on medication. Further, although both healthy controls and patients with Parkinson's disease in the "off" state had arousal-induced prolongation of reaction time, this effect was not seen in patients with Parkinson's disease on medication. These data indicate that dopaminergic neurotransmission is implicated in emotional memory and attention and suggest that dopamine mediates emotional memory via the valence dimension and emotional attention via arousal. Furthermore, our findings suggest that emotional changes in Parkinson's disease result from the effects of both the disease process and dopaminergic treatment.

Emotional processing affects movement speed.

Emotions can affect various aspects of human behavior. The impact of emotions on behavior is traditionally thought to occur at central, cognitive and motor preparation stages. Using EMG to measure the effects of emotion on movement, we found that emotional stimuli differing in valence and arousal elicited highly specific effects on peripheral movement time. This result has conceptual implications for the emotion-motion link and potentially practical implications for neurorehabilitation and professional environments where fast motor reactions are critical.

A time series analysis of falls and injury in the inpatient rehabilitation setting.

The purpose of this study is to assess whether falls and injuries are influenced by a temporal pattern (defined as a pattern based on the time of day) in the inpatient acute rehabilitation unit/hospital (IRU/H) setting. A retrospective chart review and analysis of falls and injuries among inpatients admitted to our facility during a 9-month period was performed. The sample consisted of 367 patients who had fallen at least once; 71 had repeated falls, bringing the total number of falls to 438. Significant variation in the prevalence of falls (chi2 = 24.1, p <. 01) and injuries (chi2 = 12.90, p < .01) based on time of day and shift was observed. In addition, a temporal pattern of fall-related injuries with patients who had sustained stroke and brain injury (chi2 = 12.74, p = .045) was also observed. The findings from this study allow for the development of interventions that are appropriate when falls and injury are most prevalent for different clinical populations in the IRU/H setting.

Improving outcomes of severe disorders of consciousness.

PURPOSE: To evaluate the efficacy of an Advanced Care Protocol (ACP) in improving rates of clinical progression and emergence in patients with Severe Disorders of Consciousness (SDOC). METHODS: Forty-one patients with SDOC were assigned to groups: Vegetative State (VS) traumatic etiology (VS-TBI), VS non-traumatic etiology (VS-NTBI), Minimally Conscious State (MCS-TBI), MCS non-traumatic etiology (MCS-NTBI). Design was a within-subjects retrospective case series measuring pre-post ACP intervention data. The ACP was administered sequentially over 12 weeks, incorporating traditional therapies (occupational, physical, speech), pharmaceuticals, median nerve stimulation, and neutraceuticals. Main Outcome Measures were: Pre- and post-treatment Disability Rating Scale (DRS), Functional Independence Measure (FIM), Glasgow Coma Scale (GCS), and Coma Recovery Scale-Revised (CRS-R); clinical diagnosis (VS, MCS, emerged) using criteria from the American Academy of Neurology and Mohonk Report. RESULTS: Patients significantly improved across all outcome measures, from baseline to discharge. Clinical improvement of 100% of MCS patients and 78-86% of VS patients was observed following ACP treatment. Significant differences between ACP vs. the published "standard of care" rates, in favor of the ACP, based on DRS scores and on clinical status at discharge. CONCLUSIONS: These strikingly positive results of a novel multimodal intervention are a valuable contribution to this frontier of investigation.

The pattern of cognitive-functional decline in elderly essential tremor patients: an exploratory-comparative study with Parkinson's and Alzheimer's disease patients.

OBJECTIVE: Essential tremor (ET) is a neurological disorder that produces motor, cognitive, and functional disability. However, there has been no investigation linking cognitive impairment with functional disability in ET. Therefore, we examine the similarities and differences between ET, Alzheimer's disease (AD), and Parkinson's disease (PD) in terms of the linkage between cognitive and functional impairment. DESIGN: Thirty-four ET, 26 PD, and 31 AD subjects were tested for cognition (Mini-Mental State Examination [MMSE]), motor disability (United Parkinson's Disease Rating Scale part III [UPDRS-III]), and functional disability (Minimum Data Set-Activities of Daily Living Section [MDS-ADL]). RESULTS: As expected, in PD and AD subjects, MDS-ADL scores significantly correlated with UPDRS-III and MMSE scores. The ET subjects showed a different pattern of functional disability with MDS-ADL scores significantly correlating only with MMSE scores, and with the orientation MMSE modalities. CONCLUSIONS: Our findings highlight the need to be more cognizant of the nonmotor aspects of ET, which in some patients may be more functionally disabling than the motor features themselves.

Parkinson's disease dementia: a diminished role for the Lewy body.

The literature currently views Lewy bodies as central in the pathogenesis of Parkinson's disease dementia (PDD) when Alzheimer's disease (AD) or vascular pathology is not present. Because the neuropathology of PDD is not well understood, the pathological features of PDD were characterized in eighteen PD brain specimens using published criteria for AD, Diffuse Lewy Body Disease (DLBD), and Vascular Disease as a framework. Among the PD dementia (n=16) subjects, 3 (19%) did not have LBs outside of the brain stem, nor AD or vascular pathology. In two additional cases, one did have rare LBs in the neocortex and cingulate gyrus. However, these two cases did not meet the diagnostic criteria for DLBD. Beyond these 5 cases, the remaining PD dementia subjects fitted a classical pathological profile consistent with AD (38%), vascular disease (12.5%), DLBD (6%), or a combination of these pathologies (12.5%). The findings from this study do not support the hypothesis that LBs are the main substrate for dementia in PD. More research with a larger sample size is needed to determine whether the LB may be a secondary phenomenon and/or an "innocent-bystander". The entire role of the LB in PD dementia is again brought into question.

The neuropathological basis for depression in Parkinson's disease.

Depression is found in 30-40% of all patients with Parkinson's disease (PD), but its etiology is unclear. Using neuropathology as a signpost for neurotransmitter function, we investigated the prevalence of pathological features found at postmortem and sought to uncover differences between depressed (n=11) and non-depressed (n=9) elderly PD patients. The results indicate a higher prevalence of pathological features in depressed compared to non-depressed PD patients, particularly in catecholamine areas of the brain; the locus coeruleus (neuronal loss: odds ratio=7.2, p=08; gliosis: odds ratio=18.0, p=008); dorsal vagus nerve (gliosis: odds ratio=7.63, p<0.05), and substantia nigra pars compacta (gliosis: odds ratio=2.85, ns). However, neuropathological differences were absent in the dorsal raphe nuclei, amygdala, and cortical regions. Our evidence suggests that depression in PD is related more to catecholaminergic than serotonergic system dysfunction.

The effects of withdrawal of dopaminergic medication in nursing home patients with advanced parkinsonism.

OBJECTIVE: To determine the effects of dopaminergic medication withdrawal in an elderly, demented and minimally ambulatory nursing home population with parkinsonism in New York City. METHODS: In our double-blind, randomized study, 11 patients (7 males, 4 females) were randomized into 2 groups: one group underwent levodopa medication withdrawal (experimental group) and the other group continued on their levodopa (control group). Patients were evaluated weekly over the course of a month with a neurologic examination and a series of assessment tools, including the motor UPDRS (Unified Parkinson's disease rating scale), Hoehn and Yahr staging scale, the Mini-Mental State Examination (MMSE) and the Nursing Assistant Behavioral Detection Form. SETTING: An academic nursing home in New York City. RESULTS: The patients had a mean age of 82.00 +/- 10.14 years, with a mean MMSE score of 9.50 +/- 6.60 out of 30.00 maximum. The control and experimental groups did not differ significantly with respect to age (P = .52), dementia severity (P = .35), nor severity of PD symptoms as measured by the UPDRS (P = .22) and Hoehn and Yahr staging (P = .65). Overall, no significant changes were observed between the control and experimental groups in cognitive, behavioral, and motor function across each time period. Of interest, 2 of the drug withdrawal patients showed modest improvements in cognitive function as measured by the MMSE. CONCLUSION: Our findings suggest that in patients with advanced parkinsonism and dementia, dopaminergic medication withdrawal may be a feasible way to reduce polypharmacy and potential medication-related side effects, with a minimal risk of worsening motor deterioration. Therefore, our findings may have potential implications for a medication intervention that could prevent potential deleterious side effects and improve health-related quality of life in this frail population.

Depression in Parkinson's disease: health risks, etiology, and treatment options.

Depression is found in about 30%-40% of all patients with Parkinson's disease (PD), but only a small percentage (about 20%) receive treatment. As a consequence, many PD patients suffer with reduced health-related quality of life. To address quality of life in depressed PD patients, we reviewed the literature on the health correlates of depression in PD (eg, cognitive function), etiology of depression in PD, and treatment options (ie, antidepressants, electroconvulsive therapy, and psychotherapy). The current review is unique in its focus on psychosocial aspects, as well as neuropathological factors, of depression in PD. Overall, we conclude that neurochemical (eg, serotonin) and psychosocial factors (eg, coping style, self-esteem, and social support) contribute to the affective disturbances found in this neuropsychiatric population. Therefore, we recommend that a multidisciplinary (eg, pharmacotherapeutic, psychoeducational, and/or psychotherapeutic) approach to treatment be taken with depressed PD patients.

The effects of antidepressants in Parkinson's disease: a meta-analysis.

This study explored the therapeutic effect of antidepressants in Parkinson's disease (PD) using a meta-analysis. Altogether, 24 placebo-controlled trials qualified for inclusion and revealed that tricyclic antidepressants (TCAs) had a greater antidepressant effect relative to selective serotonin reuptake inhibitors (SSRIs), Qb(1) = 8.87, p < .01, and the mono-amine-oxidase inhibitor, selegiline, Qb(1) = 7.90, p < .01. Whereas TCAs produced a significant side effect profile (odds ratio = 3.07), adverse events were negligible with SSRIs (odds ratio = 1.83) and selegeline (odds ratio = 1.63). Antidepressants can be beneficial for patients with PD. However, the choice of antidepressants needs to take depressive symptomatologies into account while monitoring side effects.

Effects of social stressors on cardiovascular reactivity in Black and White women.

BACKGROUND: Behavioral scientists have theorized that perceived racism in social interactions may account for some of the observed disparities in coronary heart disease between Black and White Americans. PURPOSE: The objective was to examine whether racial stress influences cardiovascular reactivity, a risk factor for cardiovascular disease. METHODS: We measured cardiovascular responses in Black and White women (n = 80) as they talked about 3 hypothetical scenarios: (a) being accused of shoplifting (racial stressor), (b) experiencing airport delays (nonracial stressor), and (c) giving a campus tour (control). RESULTS: Relative to White women, Black women had significantly greater mean diastolic blood pressure reactivity (3.81 vs. 0.25 mmHg; p < .05) in response to the racial stressor than in response to the nonracial stressor. Black women exhibited significantly lower heart rate during recovery following the racial stressor than during recovery following the nonracial stressor (-0.37 beats/min vs. 0.86 beats/min; p < .001). Among Black women, those who explicitly made race attributions during the racial stressor had greater systolic but not diastolic blood pressure reactivity than those who did not make racial attributions (8.32 mmHg vs. 2.17 mmHg; p < .05). CONCLUSIONS: These findings suggest that perceived racism in social interactions may contribute to increased physiological stress for Black women.

A meta-analysis of the effects of written emotional disclosure on the health outcomes of clinical populations.

A meta-analysis was conducted to examine the effects of the written emotional disclosure paradigm on health outcomes of people with physical or psychiatric disorders. After nine studies were meta-analyzed, it was determined that expressive writing significantly improved health (d = .19; p < .05). However, this positive relationship (r = .10) was not moderated by any systemic variables because of the nonsignificant test of homogeneity (Qw = 5.27; p = .73). Nonetheless, a planned contrast illustrated that expressive writing is more effective on physical (d = .21; p = .01) than on psychological (d = .07; p = .17) health outcomes (Qb > 10.83; p < .001). One explanation for the small effect size (ES) results and the nonsignificant test of homogeneity may be the small and heterogeneous samples used in some of the studies within this research synthesis. Future research with expressive writing should be tested with randomized controlled trials to increase the likelihood of detecting a larger treatment effect.

Naltrexone suppresses the late but not early licking response to a palatable sweet solution: opioid hedonic hypothesis reconsidered.

Opioid antagonists suppress the intake of sweet solutions, but typically have little effect on the initial rate of drinking. The lack of an early drug response was investigated in the present study because it questions the general idea that opioid antagonists reduce the hedonic response to sweets. The first experiment, which measured the rat's licking response to a sucrose+saccharin (S+s) solution, revealed that naltrexone suppressed S+s intake but not initial lick rates. Experiment 2A indicated that the drug's delayed behavioral effect was not due to the 10-min injection-test interval used. Increasing the interval to 20 min did not reduce the latency of drug action. Experiment 2B tested the idea that rats require several minutes to detect that naltrexone has reduced the hedonic value of the S+s solution. The S+s solution was presented either for 30 min without interruption or for 3 min followed, after a 6-min delay, by another 27-min access. In both test conditions, naltrexone did not suppress S+s licking until 7-9 min of drinking had occurred. However, the drug blocked an "appetizer effect"; a post-delay increase in licking rate produced by the split-session test procedure. Microstructure analysis indicated that in all cases, naltrexone reduced S+s licking by reducing the number of lick clusters rather than lick cluster size. In contrast to these drug effects, Experiment 2C showed that reducing the concentration of the S+s solution decreased initial lick rates. Together, these findings suggest that opioid antagonists do not affect all aspects of flavor hedonics, but may primarily alter the intake-maintaining action of palatable flavors.
