The interest in lysergic acid diethylamide (LSD) has sparked again due to its supposed positive effects on psychopathological conditions. Yet, most research focuses on the actions of LSD on the central nervous system. The interaction with the autonomic nervous system (ANS) has been neglected so far. Therefore, the aim was to assess the effects of LSD and the serotonin 2A receptor antagonist ketanserin on the ANS as assessed by heart rate variability (HRV) measures and their correlation with subjective drug-induced effects in a randomized, placebo-controlled crossover trial. Thus, ANS activity was derived from electrocardiogram recordings after intake of placebo, LSD or ketanserin, and LSD by calculating R-peak-based measures of sympathetic and parasympathetic activity. Repeated measure ANOVA and partial correlation for HRV measures and subjective experience questionnaires were performed. LSD predominantly increased sympathetic activity, while ketanserin counteracted this effect on the ANS via an increase of parasympathetic tone. Sympathetic activity was positively and parasympathetic activity negatively associated with psychedelic effects of LSD. Furthermore, Placebo HRV measures predicted subjective experiences after LSD intake. The association between trait ANS activity and LSD-induced subjective experiences may serve as a candidate biomarker set for the effectiveness of LSD in the treatment of psychopathological conditions.
Previous studies by the Cost of Blood Consensus Conference (COBCON) have used a comprehensive, standardized and generalizable activity-based costing (ABC) model to estimate the cost of red blood cell transfusions and plasma transfusion. The objective of this study was to determine the total cost of platelet transfusions in a real-world US hospital inpatient setting.
This database analysis study retrospectively collected costs for all activities related to platelet transfusion in a single-acute care US teaching hospital in 2017. Costs were collected in a stepwise manner using a custom ABC model which mapped the technical, administrative and clinical processes involved in the transfusion of platelets.
For the 15024 inpatients included in the analysis, 6335 (42·2%) were given a blood type and screen, and 941 (6·3%) received a transfusion of one or more blood products. A total of 333 platelet units were transfused in 131 patients (mean 2·54 units per patient) 211 (63·4%) units in medical inpatients and 122 (36·6%) in surgical inpatients. The total cost was $1359·99 per platelet unit, corresponding to $3457·06 per inpatient. Acquisition costs made up the largest proportion of the total cost (45·1%) followed by direct and indirect overheads (38·7%) and hospital processes costs (16·3%).
This is the first study to use an ABC costing model to determine the full cost of platelet transfusions within a US inpatient setting. This provides a useful reference point for comparisons with other transfusion products, and considerations for cost reduction.

This study was conducted to investigate the attitudes of three generations of women regarding gender roles.
In this study, 58 female students, their mothers, and grandmothers participated. Percentages and means, χ
test, Kruskal Wallis test, and multiple regression analysis were used to analyze the data.
The findings obtained in this study showed that 91.5% of the students, 89.8% of the mothers, and 84.6% of the grandmothers had an egalitarian attitude regarding gender roles. The egalitarian attitudes of students were affected onefold by the attitudes of mothers, whereas grandmothers' attitudes affected the attitudes of students 1.1 times. These two variables explain 48% of the status of having egalitarian attitudes of the students.
Students had more traditional attitudes regarding gender roles than their mothers and grandmothers.

The lack of definitive treatment or preventative options for COVID-19 led many clinicians early on to consider convalescent plasma (CCP) as potentially therapeutic. Regulators, blood centres and hospitals worldwide worked quickly to get CCP to the bedside. Although response was admirable, several areas have been identified to help improve future pandemic management.
A multidisciplinary, multinational subgroup from the ISBT Working Group on COVID-19 was tasked with drafting a manuscript that describes the lessons learned pertaining to procurement and administration of CCP, derived from a comprehensive questionnaire within the subgroup.
While each country's responses and preparedness for the pandemic varied, there were shared challenges, spanning supply chain disruptions, staffing, impact of social distancing on the collection of regular blood and CCP products, and the availability of screening and confirmatory SARS-CoV-2 testing for donors and patients. The lack of a general framework to organize data ga one.Individuals with heart failure (HF) have difficulty evaluating their symptoms, understanding when to seek health care, and implementing self-care activities. The purpose of this qualitative study was to inform the development of a heart failure action plan (HFAP) for individuals living with HF. This study used a prospective, descriptive qualitative design with a content analysis approach. The HFAP included clinical indicators of self-reported symptoms, adherence to medication regimen, and physiologic changes. Sulfosuccinimidyl oleate sodium Patients with HF reviewed the HFAP and provided their perceptions to assist in developing the action plan. Participants had a mean age of 65 years, predominately male (78%) and African American (89%). Comorbidities included hypertension, atrial fibrillation, chronic kidney disease, ischemic heart disease, valvular heart disease, and diabetes mellitus. Five thematic categories emerged (1) Understanding of symptoms and symptom severity, (2) management of symptoms, (3) educational opportunities, (4) changes, and (5) satisfaction.
