The present study aimed to investigate the effect of Namaste care on the Quality of Life (QoL) of elderly individuals with Alzheimer’s disease (AD). This quasi-experimental pre-post intervention study was conducted on 25 elderly individuals with AD who were receiving care at a nursing care center. The QoL in the Last Stage of Dementia (QUALID) questionnaire was used to evaluate QoL before the intervention. This questionnaire had 11 items across various domains and was scored on a 5-point Likert scale. All participants received Namaste care for 4 months, 7 days a week, by trained caregivers. At the end of the study, QoL was reassessed using the QUALID questionnaire. The findings revealed that the mean QoL scores before and after the intervention were 45.24±6.26 and 23.72±6.55, respectively. Namaste care significantly improved the QoL of elderly individuals with AD (P<0.001). All variables related to QoL showed improvement after the provision of Namaste care. The care for individuals with AD extended beyond medical and nursing protocols and encompassed psychological and social dimensions. Namaste care could enhance the quality of care for elderly individuals with AD.

The effect of Tocilizumab and high dose of corticosteroid on COVID-19 mortality and out-comes is equivocal. This study was designed to compare the effect of tocilizumab and Methylpredniso-lone pulse dose on mortality, outcomes and duration of hospitalization in severe COVID-19 patients.

The above research was a retrospective study conducted on 131 patients with severe COVID-19 admitted to the acute respiratory ward of Shohadaye Khalije Fars Hospital in Bushehr, Iran, from March to October 2021. Of these patients, 66 were assigned to the methylprednisolone pulse group and 65 to the tocilizumab group and the two groups were then compared in terms of clinical out-comes, laboratory test results, and lung imaging findings.

The results of the study showed that the percentage of mortality, the mean duration of hospitali-zation, and the rate of requirement for intubation were not signiciantly different between the methylpred-nisolone pulse and the tocilizumab groups (P>0.05). The improvement in CRP and arterial oxygen satura-tion was significantly different between the two groups after treatment (P<0.01). 

High dose of methylprednisolone in severely ill patients was associated with faster recovery of the patients in terms of arterial oxygenation and the inflammatory marker CRP. Nevertheless, there was no difference between the two drugs in terms of mortality rate and prognosis. Therefore methylprednisolone pulse dose can be a good alternative to tocilizumab in severe COVID-19.
