Background When the coronavirus pandemic caused widespread school and business closures in March 2020, blood drives were cancelled and the supply of blood decreased suddenly in the United States (US). In response, hospital-based transfusion medicine physicians instituted policies to conserve blood and decrease blood product usage. These efforts were aided by the US Surgeon General recommendation to cancel all elective procedures. Nevertheless, the duration, severity, and impact of the pandemic on the national blood supply was uncertain. Hospitals with in-house donor programs had the opportunity not only to control demand, but also increase supply. Study design and methods A hospital-based blood donor center was rapidly mobilized to increase the supply of in-house collected blood, in order to counteract a sudden but potentially long-term depletion of the national blood supply during a pandemic. Results Collections increased approximately five-fold above baseline for whole blood units, while apheresis platelet units were maintained at the historical average for the blood donor center. Cancellation of elective procedures showed a modest, but not yet statistically significant decrease in average blood product usage per day, nevertheless the in-house collection rate was sufficient to meet demand. Conclusion A hospital-based blood donor center can quickly increase collection volumes and capacity in the face of a national emergency / pandemic. The desire to collect units should be balanced with safety concerns, need for sustainability, and blood product demand. This article is protected by copyright.

However, several potential clinical scenarios, such as graft rejection and infection, can confound the diagnosis of suspected DILI in the setting of liver transplantation. This makes causal assessment of a new liver injury more uncertain and has traditionally precluded collection of bona fide cases of DILI affecting liver transplant patients in prospective DILI registries and cohorts. Although no studies have yet determined a greater susceptibility of the transplant patient to DILI, these subjects nevertheless present certain risk factors that can theoretically increase the risk of DILI. These include the fact that these patients are polymedicated, use drugs that are potentially hepatotoxic and can have coexisting hepatitis B or C, in addition to other factors found in non-transplant patients, such as genetic variants. Therefore, awareness of any potential hepatotoxic effect of drugs used in the liver transplant recipient and their possible implication in any case of liver dysfunction is crucial. DFOM mouse In the present article we review the most common drugs used in liver transplant recipients from a liver safety perspective and address the main pitfalls in attributing causality in this clinical setting. We also affirm the need for further research and collaboration in this somewhat neglected topic in the field of DILI.Mental disorders are thought to affect various clinical outcomes during the perioperative period. Among them, anxiety and depression are 2 of the most common types. However, the impacts of anxiety or depression on propofol requirements remain unclear. This study aimed to investigate the effects of anxiety or depression symptoms on the propofol requirements for sedation in females. This study recruited female patients aged 18 to 65 years, with American Society of Anesthesiologists physical status classification of 1 to 2, who were scheduled for hysteroscopic surgery under propofol-based intravenous anesthesia. The day before surgery, the Hospital Anxiety and Depression Scale (HADS) was used to assess the symptoms of anxiety and depression within the past 6 months. Target-controlled propofol was gradually titrated to achieve 3 desired levels of sedation Modified Observer's Assessment of Alertness/Sedation scale (MOAA/S) score 3, MOAA/S score 1, and MOAA/S score 1 and Narcotrend Index less then 65. The effect-site concentration of propofol correlated with HADS-Anxiety scores for the sedation levels of MOAA/S 3 and 1 (r = .249, P = .008; and r = .190, P = .045, respectively). However, the propofol requirements did not correlate with HADS-Depression scores at any sedation level. In conclusion, female patients with anxiety symptoms, but not depression symptoms, required a higher dose of propofol for sedation in hysteroscopy.Background Toxoplasmosis is an important opportunistic infection in immunocompromised children, especially in heart transplant recipients. This study aimed to investigate pre- and post-transplant serology for toxoplasmosis along with post-transplant PCR in pediatric heart transplant patients. Methods This cross-sectional study was performed on 38 heart transplant recipients aged 1-17 years, by the end of 2018. Pre- and post-transplant IgM and IgG titrations were measured using ELISA method. Nested PCR of B1 gene was performed to identify Toxoplasma gondii (T. gondii) infection after transplant. Results Totally, 11.4% of patients had positive IgG and 91.4% had negative IgM for toxoplasmosis before heart transplantation. The mean of pre-transplant IgG titration for sero-positive and sero-negative patients was 22.32 ± 15.30 IU/ml and 1.49 ± 1.15 IU/ml, respectively (p12 months (1.07 ± 1.27 IU/ml; p=0.004) time periods. The result of PCR for B1 gene in all cases was negative. Conclusions Chemoprophylaxis with TMP/SMX seems to be effective in prevention of T. gondii infection or reactivation among pediatric heart transplantation population .Anti-T. gondii-IgG level alone may not be sensitive enough for evaluation of the infection at least after 6 months post-transplantation.Dynamics of fires in Africa are of critical importance for understanding changes in ecosystem properties and effects on the global carbon cycle. Given increasing fire risk from projected warming on the one hand and a documented human driven decline in fires on the other, it is still unknown how the complex interplay between climate and human factors affects recent changes of fires in Africa. Moreover, the impact of recent strong El Niño events on fire dynamics is not yet known. By applying an ensemble empirical mode decomposition (EEMD) method to satellite-derived fire burned area, we investigated the spatio-temporal evolution of fires in Africa over 2001-2016 and identified the potential dominant drivers. Our results show an overall decline of fire rates, which is continuous over the time period and mainly caused by cropland expansion in northern sub-Saharan Africa. However, we also find that years of high precipitation have caused an initial increase of fire rates in southern Africa, which reversed to a decline in later years.
