nnovative but expensive drug to at-risk individuals.Both preclinical and clinical evidence supports the involvement of the endocannabinoid system in the pathobiology of cerebral ischemia. Selective cannabinoid-2 (CB2) receptor agonists exert significant neuroprotection in animal models of focal brain ischemia through a robust anti-inflammatory effect, involving both resident and peripheral immune cells. Nevertheless, no definitive studies demonstrating the relevance of CB2 receptors in human stroke exist.Using rtPCR and flow cytometry assays, we investigated CB2 receptor expression in circulating monocytes from 26 acute ischemic stroke patients and 16 age-matched healthy controls (CT). We also evaluated miR-665 expression, as potential CB2 receptor regulator. The median mRNA levels of CB2 were significantly (p  less then  0.0001) increased in total monocytes 24 h and 48 h after stroke as compared with CT. This was paralleled by elevation of miR-665 levels in monocytes collected from patients 24 h (p  less then  0.05 vs CT) and 48 h (p  less then  0.05 vs CT and p  less then  0.0001 vs 24 h) after ischemic stroke. Furthermore, an increased percentage of CB2+/CD16+ events, but not CB2+/CD14+ events, was found 24 h [20.17% (IQR, 17.22-23.58)] and 48 h [18.61% (IQR, 15.44-22.06)] after ischemic stroke when compared with CT [10.96% (IQR, 9.185-13.32)]. The percentage of CB2+/CD16+ events in monocytes was positively correlated with NIHSS score at entrance (r = 0.4327, p = 0.027). The potential beneficial functions of CD16+ intermediate and nonclassical monocytes in stroke and the elevated expression of CB2 receptor in these subsets strongly suggest that CB2 receptor agonists can be exploited for the treatment of ischemic stroke patients.The correlation between myocardial injury and clinical outcome in COVID-19 patients is gaining attention in the literature. The aim of the present study was to evaluate the role of cardiac involvement and of respiratory failure in a cohort of COVID-19 patients hospitalized in an academic hospital in Lombardy, one of the most affected Italian (and worldwide) regions by the epidemic. The study included 405 consecutive patients with confirmed COVID-19 admitted to a medical ward from February 25th to March 31st, 2020. Follow-up of surviving patients ended either at hospital discharge or by July 30th, 2020. Myocardial injury was defined on the basis of the presence of blood levels of hs-TnI above the 99th percentile upper reference limit. Respiratory function was assessed as PaO2/FiO2 (P/F) ratio. The primary end-point was death for any cause. During hospitalization, 124 patients died. Death rate increased from 7.9% in patients with normal hs-TnI plasma levels and no cardiac comorbidity to 61.5% in patients with elevated hs-TnI and cardiac involvement (p  less then  0.001). At multivariable analysis, older age, P/F ratio  less then  200 (both p  less then  0.001) and hs-TnI plasma levels were independent predictors of death. However, it must be emphasized that the median values of hs-TnI were within normal range in non-survivors. Cardiac involvement at presentation was associated with poor prognosis in COVID-19 patients, but, even in a population of COVID-19 patients who did not require invasive ventilation at hospital admission, mortality was mainly driven by older age and respiratory failure.Background In Qatar, the National Vision 2030 and the National Health Strategy 2018-2022 articulate the need to improve healthcare delivery by better utilisation of the skilled workforce. In this regard, pharmacy practice is rapidly advancing and several extended pharmacy services are now available in institutionalised settings. Objective This study aimed to determine health-related stakeholders' perceptions of current clinical pharmacy services in Qatar, and the potential development and implementation of further patient-centred roles. Setting All major organisations and institutions relating to the practice, education, regulation, and governance of pharmacy in Qatar. Method Qualitative, face-to-face semi-structured interviews were conducted with individuals in key strategic positions of policy development and influence (i.e. health-related academic leaders, healthcare policy developers, directors of medicine/pharmacy/nursing, and patient safety leaders). Participants were recruited via a combination of purp (inner setting) and were undervalued by patients and the public (outer setting). Expansion of pharmacists' clinical activities was supported, with recognition of facilitators such as the skillset and training of pharmacists, potential time release due to automation and well-considered implementation processes (characteristics of individuals, inner setting, process). Conclusion Health-related stakeholders in Qatar have positive perceptions of current clinical pharmacy services and support the expansion of pharmacist's roles. However, service development needs to consider the issues of patient and public awareness and initially target institutionalised healthcare settings.Background Early identification and treatment of cardiovascular disease (CVD) risk factors through screening are crucial in the primary prevention of CVD and reduction in healthcare-related costs. Use of Non-Physician Healthcare-workers including Community Pharmacists has been advocated as an effective and cost-efficient model of healthcare delivery. In Nigeria the use of community pharmacists for mass screening of CVD risk factors has not been explored. Objective We sought to investigate the possibility of mass CVD risk factor screening in community pharmacies by pharmacists. Setting Lagos, Nigeria. Methods Between October and December 2018 eight hundred and eighty-nine apparently healthy participants were screened for obesity, hypertension, diabetes and hypercholesterolaemia in ten community pharmacies. Diabetes and hypercholesterolaemia were screened for using point-of-care testing modalities. A structured questionnaire was used to obtain the socio-demographic data of the participants. Main outcome measures Prevalence of overweight/obesity, hypertension, diabetes, hypercholesterolaemia, smoking and alcohol intake. Results Mean age of the subjects was 56.8 ± 21.1 years. Majority (57.4%) were females. Prevalence of smoking and alcohol intake were 4.3% and 26.7% respectively. 59.7% and 71.5% of males and females were either overweight (BMI ≥ 25 kg/m2) or obese (BMI ≥ 30 kg/m2) respectively. Prevalence of hypertension was 28.2% in all subjects, 30.9% in males and 26.3% in females, p  130/80 mmHg prevalence of hypertension was 55.1%. Diabetes was detected in 3% of the subjects while 45.3% had hypercholesterolaemia. In total, 64.1% of the subjects were diagnosed with CVD risk factors for the first time. find more Conclusion Opportunistic screening for CVD risk factors is possible in community pharmacies and has the ability to detect previously undiagnosed risk factors. This community pharmacy based model could serve as a cost-effective approach to primary prevention of CVD.
