n South Africa differ significantly. check details Disparate pre-transfusion Hb between the sectors are likely due to differing disease profiles and severity, as well as differences in practice in prescribing transfusions. Implementation of a nationally co-ordinated Patient Blood Management programme may help to address these disparities and help ensure a sustainable blood transfusion system.

We describe blood supply and usage from March to December 2020 in two research medical hospitals in the Apulia region of Italy Research Hospital "Casa Sollievo della Sofferenza" (Centre 1) and University Hospital of Bari (Centre 2).

We performed a retrospective observational study of blood component transfusions in the first eight months of the pandemic 1

March-31

December 2020.We assessed the number of hospitalised patients who were transfused, the number and type of blood components donated and the number and type of blood components transfused in different care settings.

Blood donations were lower in 2020 than in 2019, with a significant reduction in red blood cells (RBC) transfused (-29% in 2020 vs 2019) and fewer transfusions in 2020 in the Internal Medicine departments (-67% and -44% in Centres 1 and 2, respectively) and Intensive C are Units (ICUs) (-53% and -54% in Centres 1 and 2, respectively). The overall number of fatalities was significantly lower in 2020 than in 2019; the proportion ofntation of a Patient Blood Management programme is essential to maintain sufficient blood supplies and to keep track of clinical outcomes that represent the most important goal of transfusion.

The number of articles evaluating the efficacy of platelet-rich plasma (PRP) in androgenetic alopecia (AGA) and alopecia areata (AA) has increased exponentially during the last years. This systematic review and meta-analysis is aimed at evaluating the benefit of PRP in the treatment of alopecia.

We searched MEDLINE (through PUBMED), Embase, and CENTRAL for relevant data. Treatment effect was described by mean difference (MD) and risk difference with 95% confidence intervals (CI). The GRADE system was used to assess the certainty of the body of evidence.

We found 27 controlled trials (1,117 subjects) that met our inclusion criteria 18 trials (713 subjects) in patients with AGA, and 9 (404 subjects) in patients with AA. Eleven studies had a split head design. There was heterogeneity in types of PRP (e.g., activated and non-activated) and administration schedules. PRP was compared to saline injections (18 studies), local steroid injections (4 studies) and other comparators (5 studies). Most commonly reported outcomes were hair density and hair regrowth. It was not possible to pool all outcome data because of heterogeneity in reporting, and because reporting was often limited to a single study. Compared to saline injections, PRP injections increased hair density over a medium-term follow-up (MD, 25.6 hairs/cm

 ; 95 % CI 2.62-48.57), but the evidence was rated as low quality due to inconsistency and risk of bias. In individuals with AA, it is unclear whether PRP injection compared with triamcinolone injection increase the rate of subjects with hair regrowth (very-low quality of evidence due to inconsistency, imprecision, and risk of bias). There were no serious adverse events related to PRP injection or control treatments.

There is limited evidence showing benefit of PRP for treatment of alopecia, and most of this evidence is of low quality.

Recent reports suggest that direct oral anticoagulants (DOAC) may induce different anticoagulant and profibrinolytic responses. We performed a head-to-head comparison of the changes in thrombin generation (TG) parameters and tissue plasminogen activator (t-PA)-induced clot lysis produced by different DOAC.

We tested 137 plasma samples from patients with non-valvular atrial fibrillation (n=72) and venous thromboembolism (n=65) under treatment with apixaban (n=38), edoxaban (n=29), rivaroxaban (n=39), or dabigatran (n=31). TG was evaluated by a fluorometric assay and fibrinolysis by measuring the lysis time of clots exposed to 40 ng/mL t-PA.

Trough-to-peak changes of TG parameters, along with correlation analysis, showed that all DOAC prolonged the lag-time in a concentration-dependent fashion. As for the other parameters, anti-factor Xa drugs markedly reduced the thrombin peak and velocity index but had little (rivaroxaban) or no effect on endogenous thrombin potential (ETP); dabigatran, instead, reducedigatran displayed profibrinolytic activity, most likely because of its distinctive effect on the TG curve.The permanent risk of splenectomized patients to infectious complications, the most severe being overwhelming post splenectomy infection (OPSI), determined the search for solutions in order to diminish these evolutionary possibilities. Therefore, intraomental developsplenic autotransplantation seems to be a viable option which, according to some authors, would have beneficial effects by restoring (at least partially) the functions of the spleen. The article presents the current experience related to this procedure (principles of surgical technique, implant location, complications, post-procedural evaluation) in an attempt to bring it back to the attention of trauma / general surgery surgeons. The procedure is simple, fast and with minimal or no complications and should be applied after any post-traumatic splenectomy.Background In the case of patients admitted with acute abdomen at the emergency department, interstitial pulmonary pathology (Covid-19 infections) represents a significant operative risk for the patients. The rate of postoperative complications is high with increased morbidity and mortality, a real challenge for the medical staff and surgical/intensive care unit teams. In emergency settings, patients were examined with targeted clinical and paraclinical parameters that assure a fast diagnosis to optimize a rapid medical and surgical treatment. Methods We conducted a retrospective comparative study that included patients enrolled and diagnosed with an acute surgical abdomen in Surgical Clinic 1 Tg. Mures Emergency County Hospital. Patients were examined and analyzed at the emergency department UPU-SMURD. We included patients admitted over the two years (2019 and 2020) and divided them into two groups. Results The total number of patients admitted in the UPU-Smurd emergency department Surgical Clinic I over theide adequate results.Introduction Abdominal injuries are responsible for approximately 20% of all post-traumatic deaths, 45-50% of which occurring in the first 60 minutes. Currently there are several prediction scores for the evolution of these patients, which take into account degrees of anatomical lesion, clinical signs and imaging and paraclinical explorations.

The aim of the study was to develop a scoring system to predict mortality in patients with abdominal trauma by using the usual biological parameters.

A retrospective, descriptive, correlational and non-interventional multicenter study was performed on a sample of 157 patients with abdominal traumata, hospitalized between 2015- 2021, in the General Surgery and the Emergency III clinics of the Emergency University Hospital Bucharest, respectively in the Surgery I Clinic of the Mures County Emergency Clinical Hospital. The following biochemical parameters were analyzed hemoglobin, hematocrit, leukocyte and platelet counts, coagulogram, glycemia, urea, creatinine, AST, Aresults of our study showed that a number of biochemical parameters may contribute to shaping a score with predictive value in terms of the evolution of abdominal trauma patients.Introduction The study is presenting a personal experience of a Trauma Centre Level I and is try to conclude on optimal medical attitude for patients with retroperitoneal hematoma, still a controversial topic for traumatologists. Material and Method A retrospective analysis of 22 cases of post-traumatic retroperitoneal hematoma admitted on Bucharest Emergency Hospital between September 2018 August 2021 (including time of Covid-19 pandemic), is presented Results The patients (males predominance, mean age 43, mean ISS of 23), benefited of nonoperative management on admission for 10 cases (45%) with a failure rate of 4/10 due to recurrent bleeding from spleen injuries and continuous bleeding from mesenteric vessels lesions. CT scan (73% - 16 cases) within 1 hour from the admission and emergency surgery were necessary for 12 cases (55%). 2 patients benefited of angioembolization on admission. Conservative attitude for retroperitoneal hematoma was adopted for 72% cases. Over-all mortality 18% (4 patients, mean ISS of 36), among 82% polytrauma cases. Conclusions Algorithm of treatment is adapted to every case of retroperitoneal hematoma but the following sequences are mandatory rapid transportation to Trauma Centre Level I with medical help, correct resuscitation, immediate relevant imagistic (CT scan), emergency surgery prior to angioembolization (for hemodynamic instable patients) or after it, ICU stabilization of the patient and then definitive repair of the injuries. Despite all, mortality remains high.Introduction The large bowel is the second most commonly injured hollow viscus in penetrating abdominal trauma following the small bowel. Injuries to the colon are fairly common in times of war and the lessons learned in these instances have historically guided management. The objective of our research is to highlight current management principles as they are applied in a single trauma centre during the last two decades. Material and Method retrospective review of our clinical experience was performed. Electronic health records from our institution were searched for injuries caused by external forces from January 2003 - October 2021. All patients that were identified with colon injuries were included in the review. Results We identified 11 male patients with colon injuries during the study period. Repair options used were primary suture or colostomy formation with no anastomoses and no damage control procedures. Mortality was 27.2%, relatively high when compared with contemporaneous studies. Conclusions The main take home message of our research is that the epidemiology of colon trauma is very different in a civilian environment that has a low caseload of penetrating injury compared to wartime injuries. There is a clear need of prospective multicentre data in this type of trauma cohorts to better define management options and not base our approach on wartime data or data from communities where the rate of penetrating injuries is high.Introduction The treatment of blunt splenic injuries showed major evolutionary changes, from fundamental/ basic splenectomy to nonoperative and endovascular treatment, "catheter surgery". Currently, in Trauma Centers, splenic angioembolization is considered the first-line intervention in trauma. This article presents the Bucharest Emergency Clinical Hospital experience in the use of splenic angioembolization, a therapeutic solution in accordance with contemporary practice and literature. Methods This retrospective study includes patients with splenic trauma by blunt mechanism, in which diagnostic / therapeutic angiography was performed, hospitalized in the Clinical Emergency Hospital Bucharest between January 2006 and December 2019. The main endpoints of the study were post-traumatic mortality, the need for surgery (laparoscopic/classic) to resolve splenic bleeding, the number of days of hospitalization, the need for hospitalization for more than 1 day in the intensive care unit, the day when the platelet count began to increase, the evolution of laboratory parameters (hospitalization, preangiography, postangiography/embolization, discharge).
