Abstract
CONTEXT Coagulation factor and endothelial injury marker, von Willebrand factor antigen (vWF:Ag), is elevated in coronavirus disease 2019 (COVID-19). OBJECTIVE To assess prognostic value of vWF:Ag for COVID-19 inpatients. DESIGN Citrated plasma samples collected from COVID-19 inpatients for D-dimer measurement were tested for vWF:Ag. Measurements of vWF:Ag and common acute phase reactants (APRs) were correlated with clinical outcomes and length of stay (LOS). RESULTS We included 333 samples from a diverse group of 120 COVID-19 inpatients. There was a clear association of higher peak measurements of vWF:Ag and other APRs with adverse clinical outcomes. Peak vWF:Ag >300% was associated with a 5-fold increased risk of death (Odds Ratio 5.08, P<.001) and a 30-fold increased risk of prolonged (>4 days) LOS (OR 29.65, P =.001). Peak D-dimer >3.8 FEU mg/L was associated with a 15-fold increase in risk of death (OR 14.73, P <.001) and a 5-fold increased risk of prolonged LOS (OR 4.55, P=.02). Using the earliest paired measurements of vWF:Ag and D-dimer from each patient and the same cut-offs, vWF:Ag was associated with a 3.5-fold increase in risk of death (OR 3.54, P=.004) and a 20-fold risk of prolonged LOS (OR 20.19, P=.004). Yet D-dimer was not significantly associated with either death (OR 1.9, P=.29) or prolonged LOS (OR 1.02, P=.98). CONCLUSIONS Both peak and early post-admission vWF:Ag >300% were highly predictive of death and prolonged length of stay among COVID-19 inpatients. Measurement of vWF:Ag may prove a valuable tool to guide escalation of COVID-19 treatment, particularly anticoagulation.

Abstract
Context Open varicocelectomy is generally performed without microscopic equipment in Iran. We report our experience with loupe-assisted inguinal varicocelectomy, and its impact on semen parameters and pregnancy rate. Subjects and Methods We conducted a retrospective interventional study on secondary data obtained from the medical records of 303 men with varicoceles, who underwent an inguinal varicocelectomy between March 2003 and April 2012. The surgical technique involved the use of a 3.0 × loupe during spermatic cord dissection at the level of the internal inguinal ring under spinal anesthesia. Semen samples were analyzed for sperm concentration, motility, and sperm morphology before the varicocelectomy and after 3 months. All the infertile patients were followed-up postoperatively for more than 1 year. Results There were 9 (3.0%) varicocele recurrences and 3 (1.0%) hydroceles. After varicocelectomy, sperm concentration and motile spermatozoa increased. In addition, spermatozoa with normal morphology improved significantly postoperatively. Of the 303 subjects treated, 153 (83.2) had a 1-year preoperative history of infertility; the spontaneous pregnancy rate of the spouses during the follow-up period was reported to be 61.4%. Conclusions The results of this research indicated that varicocelectomy using loupe-assisted inguinal technique could improve semen parameters and pregnancy rate with a low postoperative complication rate.

Abstract
BACKGROUND Transfusion-transmitted West Nile virus (WNV) infection is infrequent as a result of minipool (MP) and individual-donation (ID) nucleic acid testing (NAT) of blood donations. ID-NAT is triggered on the basis of local WNV activity identified by MP-NAT. STUDY DESIGN AND METHODS A 78-year-old male patient who was treated for cardiac disease received 14 blood components from 30 donors in August 2016. He was discharged 7 days after aortic valve replacement and coronary bypass surgery, but was re-admitted on Day 12 with symptoms of viral infection, and eventually was diagnosed with aseptic meningitis. The patent died on Day 51. RESULTS The patient was positive for WNV-immunoglobulin M (IgM) antibodies in his cerebrospinal fluid on Day 14 and was positive for WNV-IgM (on Days 14 and 16) and WNV-IgG antibodies (on Day 16) in his serum. All associated donations were nonreactive by MP-NAT or ID-NAT. However, one MP-NAT was noted to have an elevated (but negative) signal-to-cutoff ratio, and one donor from that MP was subsequently found positive for WNV-IgM and IgG antibodies; the donor was diagnosed with a WNV-like viral syndrome that had an onset 3 to 5 days postdonation. The donor's plasma was transfused 12 days before the patient's onset of WNV-meningoencephalitis. Conversion to ID-NAT was triggered for the region 7 days after the implicated donation, which was associated with the region's first human WNV case. CONCLUSION Despite the possibility of mosquito-borne transmission, this was considered to be a case of transfusion-transmitted WNV infection from an MP-NAT-nonreactive donation collected just before triggering conversion to ID-NAT; a rare event recognized once in 84 million donations.

Abstract
Up to 25% of heart transplant recipients develop rejection requiring intervention. While the majority respond to augmentation of immunomodulatory drug therapy, a subset of patients will remain refractory. Extracorporeal photopheresis (ECP) appears particularly useful in the management of select heart transplant recipients at risk of rejection, with recurrent rejection, or rejection associated with hemodynamic compromise. This chapter summarizes the current clinical experience of ECP in heart transplantation. ECP appears to favorably affect both the cellular and humoral arms of the immune response to the allograft and promote a tolerogenic profile. These immunomodulatory effects also appear to decrease development of cardiac allograft vasculopathy. ECP is generally well tolerated with few adverse effects and low infection risk.

Abstract
Early trauma-induced coagulopathy (ETIC) is abnormal coagulation detected on presentation, but a clear description is lacking. We used thromboelastography (TEG) to characterize ETIC. Data were prospectively collected on high-acuity trauma activations at an urban Level I trauma center between July 2012 and May 2013. Patients with admission TEG before any blood transfusion were stratified by Injury Severity Score (ISS): mild (less than 16), moderate (16 to 24), severe (25 or greater). TEG parameters were compared between groups. ETIC was defined as any abnormality detected on TEG. Fifty-two patients were included; mean age was 49 years and mean time to the emergency department was 26 minutes. Mean ISS for the cohort was 17 with 28 patients in mild, eight in moderate, and 16 in severe. Glasgow Coma Score was lower and head Abbreviated Injury Scale was higher in severe (P < 0.001). Forty-three (83%) patients had an abnormal TEG. Shortened reaction (R) time was noted in 42 patients. There were no differences in any TEG parameters between the injury severity groups. Hyperfibrinolysis was detected in four (8%) patients. ETIC was present in over 80 per cent of high-acuity trauma activations irrespective of injury severity and characterized primarily by shortened R time, indicating ETIC is initially described by a hypercoagulable state as a result of thrombin generation.

Abstract
In clinical laboratories, sometimes there is a need to recentrifuge the original tubes ("clot" tubes) in order to better clarify and clean the serum or plasma for further analysis. Also, the original tubes are recentrifuged to ensure there is an adequate volume of serum or plasma for multiple repeating or different tests, and/or to run additional tests that are ordered hours after the original analysis was completed. In our practice, we have encountered that recentrifugation of original tubes, including those with gel separators, does slightly change the concentration of analytes. Although there are two reports on the effect of recentrifugation on serum potassium concentration [1, 2], to the best of our knowledge there are no other studies to show the impact of re-centrifugation on the concentrations of multiple analytes that are routinely measured as part of "metabolic panel". This study investigated the effect of recentrifugation on the concentrations of glucose, sodium, potassium, chloride, BUN, creatinine, bicarbonate, calcium, phosphorus, and magnesium.

Post biopsy arterio-venous fistula in renal transplant range in incidence from 15-16%. Spontaneous resolution of 75% A-V fistulas is seen within four weeks. We report a patient with post biopsy arterio-venous fistula who had developed unexplained hypertension with no definite feature of rejection on biopsy. Doppler application revealed an arterio-venous fistula which showed spontaneous resolution in six weeks.
