The coronavirus disease 2019 (COVID-19) pandemic is exacting a disproportionate toll on ethnic minority communities and magnifying existing disparities in health care access and treatment. To understand this crisis, physicians and public health researchers have searched history for insights, especially from a great outbreak approximately a century ago the 1918 influenza pandemic. However, of the accounts examining the 1918 influenza pandemic and COVID-19, only a notable few discuss race. Yet, a rich, broader scholarship on race and epidemic disease as a "sampling device for social analysis" exists. This commentary examines the historical arc of the 1918 influenza pandemic, focusing on black Americans and showing the complex and sometimes surprising ways it operated, triggering particular responses both within a minority community and in wider racial, sociopolitical, and public health structures. This analysis reveals that critical structural inequities and health care gaps have historically contributed to and continue to compound disparate health outcomes among communities of color. Shifting from this context to the present, this article frames a discussion of racial health disparities through a resilience approach rather than a deficit approach and offers a blueprint for approaching the COVID-19 crisis and its afterlives through the lens of health equity.As the coronavirus crisis spreads swiftly through the population, it takes a particularly heavy toll on minority individuals and older adults, with older minority adults at especially high risk. L-Histidine monohydrochloride monohydrate Given the shockingly high rates of infections and deaths in nursing homes, staying in the community appears to be a good option for older adults in this crisis, but in order for some older adults to do so much assistance is required. This situation draws attention to the need for benevolent intervention on the part of the state should older adults become ill or lose their sources of income and support during the crisis. This essay provides a brief overview of public support and the financial and health benefits for older individuals who remain in the community during the pandemic. It reports the case example of Austin, Texas, a city with a rapidly aging and diverse population of almost a million residents, to ask how we can assess the success of municipalities in responding to the changing needs of older adults in the community due to COVID-19. It concludes with a discussion of what governmental and non-governmental leadership can accomplish in situations such as that brought about by the current crisis.US state-level policy often divides legal cannabis use into medical and recreational categories. However, research suggests medical and non-medical cannabis consumption often overlaps and consumers' relationship with cannabis may change. This study aimed to understand cannabis consumption from the perspective of consumers. Focus group participants shared their perspectives on motivations, settings, and contexts for consumption. A three-category taxonomy of cannabis consumption emerged from the data - Casual, intentional, and therapeutic. Within each category, there is potential for high- and low-risk behaviors. In the casual group, participants rarely purchased cannabis and only partook if it was freely available. Participants in the intentional group were knowledgeable about the effects produced by different strains, THC levels, and product types, and were frequently self-aware. In the therapeutic group, participants consumed cannabis for physical or mental health conditions. Our findings suggest the medical/non-medical dichotomy used in policy development, clinical care, and research may not reflect how regular consumers perceive the function of cannabis in their lives. Our findings suggest more research is needed to identify cannabis' role in improving quality of life, when it increases behavioral risk, and the intersection of cannabis and disability.Background The coronavirus disease 2019 is associated with neurological manifestations including stroke. Objectives We present a case series of coronavirus disease 2019 patients from two institutions with acute cerebrovascular pathologies. In addition, we present a pooled analysis of published data on large vessel occlusion in the setting of coronavirus disease 2019 and a concise summary of the pathophysiology of acute cerebrovascular disease in the setting of coronavirus disease 2019. Methods A retrospective study across two institutions was conducted between 20 March 2020 and 20 May 2020, for patients developing acute cerebrovascular disease and diagnosed with coronavirus disease 2019. We performed a literature review using the PubMed search engine. Results The total sample size was 22 patients. The mean age was 59.5 years, and 12 patients were female. The cerebrovascular pathologies were 17 cases of acute ischemic stroke, 3 cases of aneurysm rupture, and 2 cases of sinus thrombosis. Of the stroke and sinus thrombosis patients, the mean National Institute of Health Stroke Scale was 13.8 ± 8.0, and 16 (84.2%) patients underwent a mechanical thrombectomy procedure. A favorable thrombolysis in cerebral infarction score was achieved in all patients. Of the 16 patients that underwent a mechanical thrombectomy, the mortality incidence was five (31.3%). Of all patients (22), three (13.6%) patients developed hemorrhagic conversion requiring decompressive surgery. Eleven (50%) patients had a poor functional status (modified Rankin Score 3-6) at discharge, and the total mortality incidence was eight (36.4%). Conclusions Despite timely intervention and favorable reperfusion, the mortality rate in coronavirus disease 2019 patients with large vessel occlusion was high in our series and in the pooled analysis. Notable features were younger age group, involvement of both the arterial and venous vasculature, multivessel involvement, and complicated procedures due to the clot consistency and burden.Inflammation leads to atherosclerosis and acute coronary syndromes (ACS). We performed a prospective, observational study to assess association between the concentrations of inflammatory markers (high sensitivity C-reactive protein, hsCRP; high sensitivity interleukin6, hsIL-6; soluble CD40 ligand, sCD40 L) and platelet reactivity in 338 patients with ACS treated with ticagrelor and prasugrel. We also assessed whether hsCRP, hsIL-6, and sCD40 L are associated with standard inflammatory markers (white blood cell [WBC] and fibrinogen), and whether they differ according to patient diabetic status and pre-treatment with statins. Concentrations of hsCRP and concentrations of hsIL-6 and sCD40 L were assessed using turbidimetric assay and enzyme-linked immunosorbent assay, respectively. Platelet reactivity was measured using multiple electrode aggregometry. There was only a weak inverse correlation between hsIL-6 and platelet reactivity (r≤-0.125). In contrast, concentration of hsIL6 and hsCRP positively correlated with WBC count and fibrinogen (r ≥ 0.199). Insulin-dependent diabetes mellitus (IDDM) was associated with higher concentration of hsIL-6 (p = .014), whereas pre-treatment with statins - with lower concentration of hsIL-6 (p = .035). In conclusion, inflammatory state does not affect the antiplatelet efficacy of potent P2Y12 inhibitors in the acute phase of ACS, confirming the safety and efficacy of potent P2Y12 inhibitors in patients with a high inflammatory burden.Mast cells (MCs) are well known for their role in allergic conditions. This cell can be activated by various types of secretagogues, ranging from a small chemical to a huge protein. Mast cell activation by secretagogues triggers the increase in intracellular calcium (iCa2+) concentration, granule trafficking, and exocytosis. Activated mast cells release their intra-granular pre-stored mediator or the newly synthesized mediator in the exocytosis process, in the form of degranulation or secretion. There are at least three types of exocytosis in mast cells, which are suggested to contribute to the release of different mediators, i.e.,, piecemeal, kiss-and-run, and compound exocytosis. The status of mast cells, i.e., activated or resting, is often determined by measuring the concentration of the released mediator such as histamine or β-hexosaminidase. This review summarizes several mast cell components that have been and are generally used as mast cell activation indicator, from the classical histamine and β-hexosaminidase measurement, to eicosanoid and granule trafficking observation. Basic principle of the component determination is also explained with their specified research application and purpose. The information will help to predict the experiment results with a certain study design.Background The usefulness of telemedicine in the management of the coronavirus disease 2019 (COVID-19) pandemic has not been evaluated. Methods We conducted a descriptive study of the process of recruitment and follow-up of patients using a telemedicine tool (TELEA) in the management of patients at risk, in a rural environment with a dispersed population in Lugo in north western Spain. Results A large number of patients diagnosed with COVID-19 infection (N = 545) were evaluated. Of this group, 275 had comorbidities and were enrolled in the program, with a mean age of 57.6 ± 16.3 years, 43.1% male. The risk factors were hypertension (38%), diabetes (16%), asthma (9.5%), heart disease (8.8%), and immunosuppression (5.1%). Patients were followed through the platform with daily control of symptoms and vital signs. Only 8% were admitted to the hospital, 5.1% on a scheduled basis and 2.9% through the emergency room. Conclusion The telemedicine tool TELEA is useful for the management of high-risk patients with COVID-19.An increase in protein synthesis following learning is a fundamental and evolutionarily conserved mechanism of long-term memory. To maintain homeostasis, this protein synthesis must be counterbalanced by mechanisms such as protein degradation. Recent studies reported that macroautophagy/autophagy, a major protein degradation mechanism, is required for long-term memory formation. However, how learning regulates autophagy and recruits it into long-term memory formation remains to be established. Here, we show that inhibitory avoidance in rats significantly increases the levels of autophagy and lysosomal degradation proteins, including BECN1/beclin 1, LC3-II, SQSTM1/p62 and LAMP1, as well as autophagic flux in the hippocampus. Moreover, pharmacological inhibition or targeted molecular disruption of the learning-induced autophagy impairs long-term memory, leaving short-term memory intact. The increase in autophagy proteins results from active translation of their mRNA and not from changes in their total mRNA levels. Additionally, the induction of autophagy requires the immediate early gene Arc/Arg3.1. Finally, in contrast to classical regulation of autophagy in other systems, we found that the increase in autophagy upon learning is dispensable for the increase in protein synthesis. We conclude that coupling between learning-induced translation and autophagy, rather than translation per se, is an essential mechanism of long-term memory.
