To quantify the relationship of the tumor-to-normal ratio (TNR) attained from the technetium-99m macroaggregated albumin (MAA) and posttreatment yttrium-90 bremsstrahlung (Y90-Brem) single-photon emission computerized tomography (SPECT)/computer tomography (CT) studies in patients with hepatocellular carcinoma (HCC) treated with glass microspheres. Retrospectively, a total of 190 consecutive patients with HCC who underwent 204 MAA and Y90-Brem SPECT/CT for glass microsphere Y90 radiation segmentectomy (Y90-RS) or lobar treatment (Y90-RLT) between 2013 and 2018 were included. Semi-automated regions-of-interests were drawn around the targeted tumor and nontumoral liver tissue on the SPECT/CT studies. TNR values from MAA and Y90-Brem SPECT/CT were compared using paired t-tests, Pearson correlation, and median with interquartile ranges (IQR). The mean TNR for MAA and Y90-Brem SPECT/CT was 2.96 ± 1.86 (median, 2.64; IQR, 2.50) and 2.29 ± 1.10 (median, 2.06; IQR, 1.05), respectively (P < .0001). The mean Y90-RLT TNR was 2.88 ± 1.67 (median, 2.59; IQR, 0.83) and 2.17 ± 0.89 (median, 1.98; IQR, 0.81) for MAA and Y90-Brem SPECT/CT, respectively (P < .0001). The mean Y90-RS TNR was 3.02 ± 2.01 (median, 2.87; IQR, 3.01) and 2.39 ± 1.25 (median, 2.11; IQR, 1.28) for MAA and Y90-Brem SPECT/CT, respectively (P= .0003). TNR attained from MAA and Y90 SPECT/CT studies showed a moderate correlation in a positive linear fashion for the overall (r= 0.54; P < .001), Y90-RLT (r= 0.66, P < .001), and Y90-RS cohorts (r= 0.48, P < .001). The TNR attained from Y90-Brem SPECT/CT is often underestimated, positively correlated, and less variable than that attained from MAA SPECT/CT. The TNR attained from Y90-Brem SPECT/CT is often underestimated, positively correlated, and less variable than that attained from MAA SPECT/CT. DEL is the weakest known D-positive phenotype and is detectable only by adsorption and elution tests. RHD c.1227G>A is an important marker for DEL phenotype in East Asians. The aim of this study was to develop a method for RHD c.1227G>A genotyping by single-tube PCR with melting curve analysis. Two GC-rich tails of different lengths were attached to the 5'-end of allele-specific primers for RHD 1227G and 1227A alleles, such that RHD c.1227G>A could be distinguished by the melting temperature. A total of 145 D-negative Chinese Han blood donors were genotyped for RHD c.1227G>A by melting curve analysis, conventional polymerase chain reaction with sequence-specific primers (PCR-SSP), and sequencing. In 143 subjects (143/145, 98.6%), PCR-SSP and melting curve analysis produced consistent results with RHD exon 9 sequencings. Two samples were genotyped as RHD 1227G/A by PCR-SSP, but as RHD 1227A/A or A/- by melting curve analysis. These two samples were confirmed to be RHD 1227A/A or A/-. Based on RHD exon 9 sequencing, the accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the melting curve analysis for detecting both RHD 1227A and 1227G were all 100%. In contrast, the accuracy, specificity and positive predictive value of PCR-SSP for RHD 1227G detection were 98.62%, 98.21% and 94.29%, respectively, which were lower than those observed with the melting curve analysis. Melting curve analysis for RHD c.1227G>A genotyping is a simple, rapid, and reliable method, superior to conventional PCR-SSP. A genotyping is a simple, rapid, and reliable method, superior to conventional PCR-SSP.Pre-operative anaemia affects one third of patients presenting for surgery and is associated with increased peri-operative morbidity and mortality. Most studies on this subject make a distinction in acceptable haemoglobin level between sexes. We analysed data for patients undergoing major elective surgery, with pre-operative anaemia defined as haemoglobin less then 13 g/dL. Data was collected for 1074 patients, of whom 411 (38.3%) had pre-operative anaemia. https://www.selleckchem.com/products/740-y-p-pdgfr-740y-p.html The odds of red cell transfusion were significantly higher in patients with pre-operative anaemia, OR = 4.35 [95%CI OR 3.0- 6.2]. Additional binary logistic regression results identified haemoglobin level, male gender and increasing age as independent predictors for red cell transfusion. The length of post-operative stay was also significantly higher in anaemic patients, those with lower haemoglobin, males and older patients. Women were twice as likely to have a haemoglobin less then 13 g/dl as men. Women were also 3.55 times more likely not to be transfused despite being anaemic. This suggests differences in clinician's attitudes to transfusion limits in women, despite Blaudszun et al. 2018 showing that women with borderline anaemia (Hb 12-12.9 g/dL) are more likely to be transfused; to be transfused more units of red cells; and to have longer lengths of hospital stay than non- anaemic women. A change in attitude to acceptable haemoglobin in women is needed. Increased clinician awareness of the associated morbidity of even a mild reduction in haemoglobin in women is required to result in more pro-active anaemia management pre-operatively and less allogenic red cell transfusion, shorter lengths of hospital stay and overall decreased morbidity.A systematic review based on the PRISMA guidelines was conducted to investigate and compare treatment with hyaluronic acid (HA), corticosteroids, and blood products in patients with temporomandibular joint osteoarthritis (TMJOA). The MEDLINE/PubMed, Embase, and Cochrane Library databases were searched for articles published until September 25, 2019. Articles met the inclusion criteria if they reported patients with TMJOA, a comparison group, and a follow-up period of at least 6 months. The mean and standard deviation for TMJ pain and maximum mouth opening (MMO) were reported. Nine studies involving 443 patients were included. Injectables and Ringer's lactate solution or normal saline were reported to significantly improve TMJ pain and MMO. Regarding TMJ pain, two studies showed a significant superiority of plasma rich in growth factors (PRGF)/platelet-rich plasma (PRP) injections with or without arthrocentesis over HA, but HA showed a significant improvement compared to corticosteroids. For MMO, no injectable was found to be superior to Ringer's lactate or a normal saline control, but arthrocentesis + PRP resulted in MMO improvement compared to arthrocentesis + HA.
