Handling Ensemble N-Representability Concern in Explicit-by-Implicit Way.
In patients with moderate to severe qualitative and quantitative von Willebrand disease (VWD), even minor surgical procedures can be associated with a risk of life-threatening bleeding. Treatment strategies vary according to the levels of von Willebrand factor (VWF) and Factor VIII (FVIII). The aim of this study was to evaluate the effectiveness and the safety of Voncento
(CSL Behring, Marburg, Germany), a plasma-derived FVIII/VWF concentrate (ratio 12.4), during surgeries performed in patients with inherited VWD.

The OPALE study, a French multicentre observational study, was carried out from May 2016 to May 2019. It evaluated and analysed patients with inherited VWD (any type) requiring treatment with Voncento
who underwent surgery.

In total, 92 patients were enrolled, and 66 patients underwent 100 surgical procedures 69 minor and 31 major surgeries conducted in 30 patients with type 1, 50 patients with type 2, and 20 patients with type 3 VWD. During minor surgeries, the median number of infusions ents with all VWD types.
Proteasomes are proteolytic complexes with prominent roles in the control of protein homeostasis and cellular viability. However, little is known about the effects of storage and glucose-6-phosphate dehydrogenase deficiency (G6PD
) on the activity and topology of red blood cell (RBC) proteasomes.

We investigated the concentration (by GeLC-MS proteomics analysis and immunoblotting), activity (by using peptide substrates and proteasome inhibitors), and subcellular/extracellular distribution (following cell fractionation and isolation of extracellular vesicles, respectively) of RBC proteasomes in fresh blood and RBCs from control and G6PD
donors following storage in leukoreduced units. RBC proteasome activity was also tested in transfusion-mimicking conditions in vitro.

Stored RBCs were characterised by decreased cytosolic proteasome activity compared to fresh RBCs but increased membrane activity and protein concentration levels. Active proteasomes along with other "repair or destroy" proteins are recruion, activity, and release of RBC proteasomes. The partial irreversibility of these effects in transfusion-mimicking conditions demands further investigation of their clinical impact on transfusion outcomes.
Rh antigens are critical in haemolytic disease of the foetus and newborn (HDFN). The D-- phenotype is a rare blood group characterised by the lack of expression of C, c, E and e antigens at the surface of red blood cells because of mutations in both RHCE alleles inactivating the expression of a "normal" protein. The aim of the study was to determine the molecular basis of D-- individuals of Indian origin.

Ten Rh D-positive postnatal women who had produced antibodies against all Rh antigens, except D, leading to HDFN and foetal loss, were investigated. Extensive serological and molecular (polymerase chain reaction [PCR] using sequence-specific primers), quantitative multiplex PCR of short fluorescent fragments (QMPSF), and Sanger sequencing analyses were carried out.

Serological testing with anti-C, anti-c, anti-E, and anti-e reagents showed absence of the four antigens in all ten index cases, as well as in three siblings. Flow cytometry indicated absence of these antigens with a typical exalted expressiications involved in such pregnancies.
Although the widespread use of factor VIII/IX replacement therapy has significantly reduced the severity of arthropathy in persons with haemophilia (PWH), some develop degenerative joint changes, associated with significant pain. The aim of this survey was to investigate the management and perception of pain among Italian physicians who treat PWH.

Between September and October 2017, a questionnaire was distributed to 35 Italian haemophilia treatment centres (60 physicians).

Fifty-three haemophilia specialists completed the survey. We found that there was good agreement (98.1%) on the need to investigate pain at each clinical visit, but there was heterogeneity in the opinions of haemophilia specialists with regards to the availability of validated guidelines (35.8%) and whether pain specialists should be a part of the comprehensive care team in daily clinical practice (58.5%). Haemophilia specialists also agreed pain should be evaluated using a rating scale validated in PWH (88.7%). Pain was mainly manags to use, as well as a reluctance to involve pain specialists. The lack of spontaneous reporting of pain by PWH, despite using pain relief, highlights the need for clinicians to actively ask patients about any pain they may be experiencing.
This study aimed to review results of urinalysis with flow cytometry technique at the time of diagnosis of urinary tact infection (UTI), and to determine uropathogenes with their antibiotic resistance patterns in children with first-time UTI.

This single-centered, retrospective, cross-sectional study was conducted from January 2015 to December 2017. The study included 361 children with a first-time UTI diagnosis. Age, gender, results of automated urinalysis, urine culture results were recorded.

Mean ages of children were 55.8±50.7 months. E. coli was the most common isolated microorganism followed by K. pneumoniae, Proteus, Enterococcus, and P. read more aeroginosa. Median count of pyuria was 44 leukocyte/mm
(range0-2954/mm
). Median count of pyuria in female and male patients were 53 and 22 leukocyte/mm
, respectively (p=0047). A total of 98 patients (27.1%) had no pyuria. Proportion of pyuria in female and male patients were 81.2% and 76%, respectively (p>0.05). Mean age of patients with and without pyurl treatment choices limited.
This study aimed to investigate the risk factors of fistula recurrence after primary urethrocutaneous fistulectomy in children with hypospadias.

The study included 63 children who underwent fistulectomy for urethrocutaneous fistula (UCFs) that occurred after urethroplasty for hypospadias, between February 2009 and December 2018. The patients were divided into 2 groups successful group 1 and failed group 2. For data analysis, we included the demographics of the patients, the details of the previous urethroplasty (the type of hypospadias and the location of the meatus after complete chordectomy), the presence of meatal stenosis or urethral stricture after urethroplasty, and the size of the UCFs. The Student t-test and the chi-square test were performed to analyze the data using the Statistical Package for Social Sciences software.

The overall success rate of primary urethrocutaneous fistulectomy was 81.0% (51/63 children). The most common location of a secondary fistula was the penoscrotal area 5 (41.6%).
