Risk factors for inappropriate blood requisition among hospitals in Tanzania

Background Blood is a critical aspect of treatment in life saving situations, increasing demand. Blood requisition practices greatly effect sufficient supply in blood banks. This study aimed to determine the risk factors for inappropriate blood requisition in Tanzania. Methods This was a cross sectional study using secondary data of 14,460 patients’ blood requests from 42 transfusion hospitals. Pr

Enhancement of 2DEG effective mass in AlN/Al0.78Ga0.22N high electron mobility transistor structure determined by THz optical Hall effect

We report on the free charge carrier properties of a two-dimensional electron gas (2DEG) in an AlN/AlxGa1-xN high electron mobility transistor structure with a high aluminum content (x = 0.78). The 2DEG sheet density N s = (7.3 ± 0.7) × 10 12 cm-2, sheet mobility μ s = (270 ± 40) cm2/(Vs), sheet resistance R s = (3200 ± 500) ω / □, and effective mass m eff = (0.63 ± 0.04) m 0 at low temperatures (

Survival and risk of vascular complications in myelofibrosis—A population-based study from the Swedish MPN group

Objective: To gain knowledge of underlying risk factors for vascular complications and their impact on life expectancy in myelofibrosis. Methods: From a cohort of 392 myelofibrosis patients registered in the Swedish MPN registry 58 patients with vascular complications during follow-up were identified. Patients with vascular complications were compared with both 1:1 matched controls and the entire

Of Swedes & Facebook 2022

2022 has not been a good year for Facebook (Meta) so far. The stock price is plunging, the company is still under fire for the extent of misinformation on the platform, and the number of users are decreasing for the first time in the US. Marketing and technology analysts are speculating whether Facebook reached its peak and began losing the competition against other rising platforms like TikTok.Ye

Data standards for acute coronary syndrome and percutaneous coronary intervention : the European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart)

Standardized data definitions are essential for monitoring and benchmarking the quality of care and patient outcomes in observational studies and randomized controlled trials. There are no contemporary pan-European data standards for the acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroH

Squeezed in Midlife : Studies of unpaid caregiving among working-age men and women across Europe

Population ageing means that increasingly many are faced with the dual demands of paid work while providing unpaid care to older family members. Caregiving requires time and energy, with implications for paid work and well-being. The challenges faced by individuals add up and therefore also impact national economies. This dissertation provides insights into the implications of unpaid caregiving fo
