Introduction. Platelet function, platelet volume indices, traditional markers of lipid metabolism, inflammatory markers and a novel biomarker, cyclophilin A (CyPA), are related as far as they have implications in pathogenesis of atherosclerosis. The purpose of this study was to evaluate interrelations among these factors, correlation between platelet function and inflammatory factors, also a function of CyPA. Materials and methods. 160 male patients with high risk of atherosclerosis and metabolic syndrome were included in the study. Inclusion criteria were as follows: disturbances in lipids profile, increased weight, smoking, acute or chronic stress, no previous or current acute cardiovascular disease (CVD), high risk and presence of stress confirmed by physician. CRP, vWF, fibrinogen, CyPA levels were measured. Platelet function was assessed by aggregation and flow cytometry. Results. Increasing number of risk factors gave statistically significant elevation in fibrinogen, thrombin receptors activating peptide, CRP, glucose, mean platelet volume (MPV), platelet large cell ratio, lipids and their ratios with extremely significant linearity. MPV correlated positively with CD42a (r = 0.605; p

Abstract Background Influenza remains a significant public health burden, resulting in serious morbidity and mortality globally. The National Institute for Health and Care Excellence (NICE) recommends treatment with antivirals for a broad range of high-risk influenza cases; however, anecdotal reports suggest treatment rates in the United Kingdom remain low. Real-world evidence on influenza treatment patterns in this region is limited. We therefore sought to investigate the proportion of influenza cases presenting to UK primary care facilities that receive antiviral treatment. Methods Data were obtained from the Clinical Practice Research Datalink (CPRD), a database of medical records from 674 primary care facilities in the UK. Cases were eligible for study inclusion if a diagnosis code for influenza or influenza-like illness (ILI) occurred between 1 January 2003 and 31 December 2018, and the medical record had sufficient data quality. Treatment was defined as prescription of an antiviral (oseltamivir, zanamivir, peramivir, or amantadine) within ±10 days of diagnosis. We examined (1) treatment rates, overall and by study year to understand time trends, (2) distribution of antiviral types prescribed, and (3) patient characteristics across treatment status. Results Of the 116,923 cases of influenza that met study inclusion criteria, 10,923 (9.3%) were treated with an antiviral. Treatment rates varied by study year, ranging from <1.0% in 2004 to 24.0% in 2009. The most recent study year (2018) had a treatment rate of 11.2%. Oseltamivir was the most frequent antiviral prescribed, followed by zanamivir. Treated cases of influenza were younger and more likely to be female compared with untreated cases. Conclusion We evaluated real-world estimates of influenza treatment rates over a 16-year period in UK primary care settings, where anecdotal reports suggested low treatment rates. Consistent with these reports, we observed low treatment rates, likely due in part to inclusion criteria and clinical guidelines specifying treatment only for high-risk cases. Subsequent analyses will investigate treatment patterns and patient characteristics in high-risk vs. low-risk cases to provide additional context for observed treatment rates.

SummaryAlthough dimethyl sulfoxide (DMSO) has been used extensively as a cryopreservative for platelets there are few studies dealing with the effect of DMSO on platelet function. Using techniques similar to those employed in platelet cryopreservation platelets were incubated with final concentrations of 2-10% DMSO at 25° C. After exposure to 5 and 10% DMSO platelets remained discoid and electron micrographs revealed no structural abnormalities. There was no significant change in platelet count. In terms of injury to platelet membranes, there was no increased availability of platelet factor-3 or leakage of nucleotides, 5 hydroxytryptamine (5HT) or glycosidases with final DMSO concentrations of 2.5, 5 and 10% DMSO. Thrombin stimulated nucleotide and 5HT release was reduced by 10% DMSO. Impairment of thrombin induced glycosidase release was noted at lower DMSO concentrations and was dose related. Similarly, aggregation to ADP was progressively impaired at DMSO concentrations from 1-5% and was dose related. After the platelets exposed to DMSO were washed, however, aggregation and release returned to control values. Platelet aggregation by epinephrine was also inhibited by DMSO and this could not be corrected by washing the platelets. DMSO-plasma solutions are hypertonic but only minimal increases in platelet volume (at 10% DMSO) could be detected. Shrinkage of platelets was seen with hypertonic solutions of sodium chloride or sucrose suggesting that the rapid transmembrane passage of DMSO prevented significant shifts of water. These studies demonstrate that there are minimal irreversible alterations in in vitro platelet function after short-term exposure to DMSO.

Abstract Background/Introduction The PEGASUS-TIMI 54 trial showed that prolonged treatment with ticagrelor reduces the cumulative occurrence of ischemic adverse events. CLARIFY is the biggest real life registry on chronic coronary syndrome. Purpose - To evaluate the percentage of patients eligible for long-term ticagrelor therapy in the CLARIFY registry. – To compare the outcome of this subgroup of patients with those with PEGASUS exclusion criteria or without PEGASUS inclusion criteria. Methods Within the CLARIFY population, we selected post MI patients and we excluded those with missing info (post MI evaluable population). Then, we divided patients into 3 groups: excluded (meeting PEGASUS exclusion criteria, namely use of P2Y12 receptor antagonists or chronic oral anticoagulant, any stroke, coronary-artery bypass grafting in the past 5 years); eligible (meeting PEGASUS high-risk inclusion criteria, namely age≥65 years; diabetes; multivessel disease; creatinine clearance &lt;60 ml/min) and ineligible (not meeting PEGASUS high-risk inclusion criteria). We therefore compared the ischemic (CV death, MI and stroke) and bleeding (major bleeding) outcome of the 3 groups adjusting for age, sex, smoking and geographical region. Results Among the 11811 post-MI evaluable patients, 4706 (39.8%) were included in the eligible group, 5715 (48.4%) in the excluded group, and 1390 in the ineligible group (11.8%). Both the ischemic and bleeding endpoints were significantly different among the 3 groups with the excluded patients with the worst and ineligible patients with the best outcome (see table). The same trend was shown for CV death, while the occurrence of MI was not significantly different among the 3 groups. In the eligible group, the ratio between ischemic and bleeding events was 6:1, whereas between CV death and major bleeding was 3.5:1. Conclusions Around 40% of CLARIFY post-MI patients could benefit from prolonged ticagrelor therapy. In this group of patients, ischemic risk seems to be higher than the bleeding one.

Background: Albumin has been shown to decrease the incidence of mortality and acute kidney injury (AKI) in patients with spontaneous bacterial peritonitis (SBP). Albumin administration in SBP is recommended within 6 hours of diagnosis and for reserved use in high-risk patients with the following baseline laboratory tests: serum creatinine >1 mg/dL, blood urea nitrogen >30 mg/dL or total bilirubin >4 mg/dL. Objective: We aimed to assess the impact of an albumin order set restricted to high-risk SBP. Methods: A retrospective cohort study was conducted between Jan 1, 2013 to Feb 28, 2018. The albumin order set was implemented on Sep 20, 2016. Patients were included if they were diagnosed with SBP and had an ascitic fluid polymorphonuclear count ≥ 250 cells/mm3. Results: Out of a total of 137 patients reviewed, 88 met the inclusion criteria. The incidence of AKI in the pre-order set and post-order set were 63.93% and 33.33% (p = 0.01), respectively. The incidence of mortality in the pre-order set and post-order set were 36.07% and 7.41% (p = 0.005), respectively. The percentage of patients administered albumin within 6 hours were 24.59% to 40.74% (p = 0.14) in the pre-order set and post-order set, respectively. The percentage of patients who received the recommended albumin dosing regimen ordered was 42.62% vs 96.30% (p < 0.001), in the pre-order set and post-order set, respectively. Conclusion: The albumin order set restricted to high-risk SBP patients significantly reduced the incidence of AKI and mortality, and improved the appropriateness of albumin regimen ordered.

Abstract Introduction Peri-implant fluid more than 6 months from surgery is a known complication of breast surgery.Differential diagnosis includes infection, inflammation,implant rupture and haematoma.Other than infection raised no concern until the identification of Breast Implant Associated Anaplastic Large Cell Lymphoma(BIA-ALCL). Method Retrospective electronic data collection for women 18 years or older who met the following inclusion criteria:(a)oncoplastic and/or cosmetic reconstructive surgery with placement of implant(b)peri-implant fluid collection after 6-36 months. Results In total,17 women with implants with a mean age of 56 years were included in the study.The mean time between reconstructive surgery and the peri-implant fluid collection was 23 months.The median peri-implant fluid collection size was 143 ml.14 of the 17 peri-implant fluid collections were benign.12 of 14 had polyurethane-coated textured implants.4 of the 17 were BIA-ALCL. Conclusions The current literature suggests that late peri-implant seromas arise from friction as the implant moves within the cavity and that this friction is increased with textured rather than smooth implants.In our unit 12/14 of the benign collections appeared in reconstructions with polyurethane implants.Furthermore,BIA-ALCL should always be considered in this situation and aspirate should be sent for cytology.Is this change in polyurethane implants a new entity?

Background and aims: Early prediction of the effect of vedolizumab (VDZ) in inflammatory bowel disease (IBD) is of paramount importance to guide clinical decisions. This study assessed whether early fecal calprotectin (FC) can predict endoscopic response and histologic remission after VDZ initiation. Methods: This was a prospective study. Inclusion criteria were endoscopic inflammation and FC >100 µg/g. FC was determined at baseline and weeks 2, 4, 8 and 16. At week 16, endoscopies with ileal and colonic biopsies were performed. FC changes were assessed with Wilcoxon Rank Sum tests. ROC statistics were used to assess the diagnostic accuracy of FC. Results: In total, 45 patients [27 Crohn’s disease (CD), 16/2 ulcerative colitis (UC)/IBD-unclassified] [40% males, median age 39 (28–51) years] were included. Week 16 endoscopic response and histologic remission rates were 58% and 33%. A median 37% decline in FC at week 2 was observed only in endoscopic responders, p = 0.025. FC <250 µg/g at week 8 predicted endoscopic response in both UC and CD (positive predictive value 100%), whereas absence of FC decline at week 8 corresponded with absence of endoscopic response in CD [negative predictive value (NPV) 82%] and absence of histologic remission in both UC and CD (NPV 90%). Conclusion: The onset of a decline in FC as early as week 2 is associated with endoscopic response to VDZ induction. FC <250 µg/g at week 8 is associated with endoscopic response, whereas absence of FC decline at week 8 is associated with absence of both endoscopic response and histologic remission. FC levels 8 weeks after the start of VDZ could be used to guide clinical decisions and might substitute for endoscopic response evaluation.

Abstract Aims Long-term success of Sleeve Gastrectomy (SG) is undermined by weight regain (WR). Several procedure- and patient-specific factors have been proposed in previous studies. Here we look at 18-month follow-up post-SG to investigate WR and patient-specific variables influencing this. Methods A single-centre study involving retrospective analysis of a prospectively-maintained database. Inclusion criteria: Primary non-revisional SG patients with adequate follow-up data to assess WL/WR trends. Patients were divided into two subgroups based on their %EWL between 6-to-12 and 12-to-18 months: weight regainers (WR) and weight losers/maintainers (WL/M). Results Out of 338 SG cases between 2012-2017, 180 met inclusion criteria of which 18.3% were men and 45% were super-obese. All patients lost weight during first 6 months (mean %EWL 52.3%, P &lt; 0.0001). Between 6-to-12 months, 87.6% patients continued WL with a further mean %EWL of 10.35% (P &lt; 0.0001). Between 12-to-18 months, a drastic deceleration/reversal of WL progress was observed with an average of only 0.76% EWL (P = 0.84), with 42% of patients regaining weight in this period (mean EWG 6.8%). Male patients encountered significantly higher WR rate (OR 3.27, P = 0.003), whereas it was much less frequent in pre-operatively super-obese patients (OR 0.48, P = 0.036). Moreover, there was no difference in the 6-month %EWL between WR and WL/M subgroups (P = 0.62), thus negating the possibility of WL burn-out phenomenon. Conclusions Different rates of WR in men and super-obese patients may indicate underlying behavioural and biological differences. More research is needed to investigate them in detail, having implications for revisional surgery and follow-up support.

Abstract Background Irisin is an adipomyokine with a promising potential for the treatment of metabolic disturbances and endothelial dysfunction. This study aimed to explore the effect of irisin on metabolic and platelet functions, and to explore the possible involvement of soluble receptor of advanced glycation end product (sRAGE) in the type 2 diabetes mellitus (T2DM) rat model. Thirty-three adult male albino rats were divided into three groups: normal control, vehicle-treated T2DM group, and irisin-treated T2DM. At the end of the study period, metabolic parameters, platelet count, mean platelet volume, platelet distribution width, plateletcrit, and serum sRAGE were determined. Results Irisin significantly improved platelet function and metabolic derangements induced by T2DM and significantly increased sRAGE. sRAGE was significantly negatively associated with platelet function parameters and some glucometabolic parameters. Additionally, mean platelet volume showed a significant predictive value for the change in serum sRAGE. Conclusions Irisin could have a protective role against diabetes-induced platelet dysfunction by increasing sRAGE levels, indicating the potential beneficial effects of sRAGE in the type 2 diabetic rat model.

Diabetes Mellitus (DM) is a state of chronically hyperglycemia, which is caused by impaired insulin secretion and function. Thealteration in coagulation system in DM patients served as the basic etiology of macro and micro vascular complication. Platelets are oneof the factors that have a role in the coagulation system and undergo pathological changes in DM patients. Mean Platelet Volume (MPV)is an indicator of platelet function and activation. Larger platelets have more dense and more reactive pro coagulant granules. The aimof this study was to know whether there were differences in MPV between DM patients compared to medical check-up participants atthe Dr. Hasan Sadikin Hospital, Bandung.. The research used analytical descriptive, retrospective data. The inclusion criteria of thisresearch was DM patients and medical check up participants whose serum fasting glucose and two (2) hours post prandial serum glucosewere within the normal range. The data were taken from medical records of DM patients and medical check up participants. The datawere further analyzed with SPSS ver. 15 program using unpaired T-test. In this study, no significant difference between DM patientsand medical check up participants (p>0.05) was found. It can be concluded that Mean Platelet Volume if used as single, can not predictvascular complication in DM patients.
