Abstract
INTRODUCTION Intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator is beneficial in acute ischaemic stroke (AIS). We aim to compare the realworld clinical outcomes and service efficiency of IVT in Malaysian primary stroke centres (PSCs) versus acute stroke ready hospitals (ASRHs). MATERIALS AND METHODS We conducted a multi-centre cohort study involving 5 PSCs and 7 ASRHs in Malaysia. Through review of medical records of AIS patients who received IVT from 01 January 2014 to 30 June 2021, real-world data was extracted for analysis. Univariate and multivariate regression models were employed to evaluate the role of PSCs versus ASRHs in post-IVT outcomes and complications. Statistical significance was set at p<0.05. RESULTS A total of 313 multi-ethnic Asians, namely 231 from PSCs and 82 from ASRHs, were included. Both groups were comparable in baseline demographic, clinical, and stroke characteristics. The efficiency of IVT delivery (door-toneedle time), functional outcomes (mRS at 3 months post- IVT), and rates of adverse events (intracranial haemorrhages and mortality) following IVT were comparable between the 2 groups. Notably, 46.8% and 48.8% of patients in PSCs and ASRHs group respectively (p=0.752) achieved favourable functional outcome (mRS≤1 at 3 months post-IVT). Regression analyses demonstrated that post-IVT functional outcomes and adverse events were independent of the role of PSCs or ASRHs. CONCLUSION Our study provides real-world evidence which suggests that IVT can be equally safe, effective, and efficiently delivered in ASRHs. This may encourage the establishment of more ASRHs to extend the benefits of IVT to a greater proportion of stroke populations and enhance the regional stroke care.

Rehabilitation after proximal interphalangeal joint replacement: A structured review of the literature. HAND SURGERY & REHABILITATION 2021; 41:14-21. [PMID: 34619399 DOI: 10.1016/j.hansur.2021.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/07/2021] [Accepted: 09/14/2021] [Indexed: 11/29/2022]
Abstract
Proximal interphalangeal (PIP) joint arthroplasty is an unsolved biomechanical challenge despite advances in materials and new implant designs. This leads to a high rate of complications. Moreover, there is heterogeneity in postoperative management according to the literature. The present structured review examined the therapeutic strategies utilized by physiotherapists to restore a functional finger chain and prevent postoperative complications following PIP joint replacement. Patients undergoing primary total PIP joint arthroplasty of the index, ring, middle or little finger were included. Articles published from 2008 onwards, in French or English, and reporting on PIP joint replacement and postoperative management, were included. Therapeutic strategies were organized according to the surgical approach. Details of splint strategies, mobilization and muscle strengthening and management of postoperative complications were collected. Forty-eight studies, 3 of which provided a description of surgical techniques, were included. In relation to hand function, most authors advocated joint mobilization (n = 45) and some recommended muscle strengthening (n = 4). Static (n = 43) and dynamic splints (n = 14) and buddy taping (n = 12) were frequently recommended to prevent and manage postoperative complications. Few studies (n = 13) reported wound assessment or control of postoperative edema. Precise recommendations concerning therapeutic strategies following PIP joint arthroplasty cannot be made based on available evidence. Specific protocols for rehabilitation following PIP joint replacement need to be clarified in future research.

Abstract
The electrochemical behavior of 1-ferrocenylmethyl-3-(methyl)-imidazolium iodide (or mesityl) imidazolium was studied by cyclic voltammetry at glassy carbon electrode in midiums organic to determine the influences of electronic imidazolium group on the ferrocene. The experimental results indicated that the redox reaction was reversible. Mass transport towards the electrode is a simple diffusion process and the diffusion coefficient (D) for redox couple has been also calculated and we have evaluated the heterogeneous charge transfer rate constant (K0).

Abstract
Antiviral therapy to eradicate hepatitis C virus (HCV) infection improves outcomes in patients undergoing liver transplantation (LT) for advanced chronic HCV with or without hepatocellular carcinoma. Traditionally, antiviral therapy focused on the use of interferon (IFN)-based regimens, with antiviral treatment initiated in the posttransplant period once recurrent HCV disease with fibrosis in the allograft was identified. The use of IFN-based therapy was limited in pretransplant patients with advanced liver disease. Earlier intervention, either before transplantation or early after LT, is now feasible with the advent of second-generation direct-acting antiviral agents (DAAs) with superior tolerability and efficacy to IFN-based therapy. These agents have the potential to reduce the number of patients developing HCV-related complications requiring LT and retransplantation, as well as reducing the demand for donor organs. We discuss the pros and cons of pretransplant, peritransplant, and posttransplant therapy with current DAAs, citing available data from clinical trials and real-world experience.

Safety of sofosbuvir-based regimens after liver transplantation: longitudinal assessment of renal function in the prospective ANRS CO23 CUPILT study. Aliment Pharmacol Ther 2018; 47:1682-1689.

Abstract
BACKGROUND In liver transplant recipients with hepatitis C virus recurrence, there is concern about renal safety of sofosbuvir-based regimens. Changes in serum creatinine or in the estimated glomerular filtration rate (eGFR) under treatment are used to look for possible renal toxicity. However, serum creatinine and eGFR are highly variable. AIM To analyse renal function trajectory with numerous assays of serum creatinine over a long period of time. METHODS In a multicentre cohort of 139 patients, the eGFR was obtained from serum creatinine using the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation. Slopes of eGFR were defined as a change in eGFR during a period divided by time. Pre-treatment, on-treatment and post-treatment periods were 9 months, 3-9 months and 4.5 months. Interactions between eGFR slopes and the pre-treatment eGFR, use of ribavirin or mycophenolate mofetil, and stage of fibrosis were addressed. On-treatment eGFR slopes were separated in tertiles. Pre- and post-treatment eGFR slopes were compared globally and according to tertiles. RESULTS The post-treatment eGFR slope was significantly better than pre-treatment eGFR slope (+0.18 (IQR -0.76 to +1.32) vs -0.11 (IQR -1.01 to +0.73) mL/min/1.73 m2 /month, P = 0.03) independently of the pre-treatment eGFR (P = 0.99), ribavirin administration (P = 0.26), mycophenolate mofetil administration (P = 0.51) and stage of fibrosis (F3 and F4 vs lower stages, P = 0.18; F4 vs lower stages, P = 0.08; F4 Child-Pugh B and C vs lower stages, P = 0.38). Tertiles of on-treatment eGFR slopes were -1.71 (IQR -2.54 to -1.48), -0.78 (IQR -1.03 to -0.36) and +0.75 (IQR +0.28 to +1.47) mL/min/1.73 m2 /month. Pre- and post-treatment eGFR slopes were not significantly different according to tertiles (respectively, P = 0.34, 0.08, 0.73). CONCLUSION The eGFR varies during treatment and gives a confusing picture of the renal safety of sofosbuvir-based regimens. In contrast, longitudinal assessment of the eGFR shows a rising trajectory over longer time, meaning that these therapies are safe for the kidneys in our cohort of liver transplant recipients.

Abstract
Management of invasive aspergillosis of the paranasal sinuses requires sufficient experience to initiate appropriate investigations and then utilize the correct treatment protocol. Computed tomography (CT) or magnetic resonance imaging (MRI) is essential to show the extent of the disease and diagnosis is confirmed by histological analysis. Aspergillus flavus is a ubiquitous soil saprophyte in the Sudan and is responsible for many cases originating from this area. The literature is reviewed and treatment options discussed.

Antibody-dependent and antibody-independent uptake of HBsAg across human leucocyte subsets is similar between individuals with chronic hepatitis B virus infection and healthy donors. J Viral Hepat 2017; 24:506-513.

Abstract
Maintaining detectable levels of antibodies to hepatitis B surface antigen (HBsAg) in serum after HBsAg sero-conversion is the key clinical endpoint indicative of recovery from infection with hepatitis B virus (HBV). As HBV-infected hepatocytes secrete HBsAg subviral particles in vast excess over HBV virions, detectable hepatitis B surface antibody (anti-HBs) titres imply complete elimination of HBV virions as well as HBsAg particles. Although intrahepatic phagocytes, for example Kupffer cells, are thought to mediate clearance of HBsAg via antibody (Ab)-dependent and Ab-independent mechanisms, the relative contributions of circulating phagocytic cell types to HBsAg elimination are poorly characterized. Understanding the role of various immune cell subsets in the clearance of HBsAg is important because Ab-dependent or Ab-independent phagocytic HBsAg uptake may modulate presentation of HBsAg-derived epitopes to antigen-specific T cells and hence plays a critical role in adaptive immunity against HBV. This study aims to characterize phagocytic leucocyte subsets capable of internalizing HBsAg immune complexes (HBsAg:IC) or un-complexed HBsAg particles in whole blood directly ex vivo. The data show that uptake of HBsAg:IC occurs most prominently in monocytes, B cells, dendritic cells and in neutrophils. In contrast, B cells, and to a lesser degree also monocytes, seem to be effective phagocytes for un-complexed HBsAg. Importantly, a similar pattern of phagocytic HBsAg uptake was observed in blood from chronic hepatitis B (CHB) patients compared to healthy controls, suggesting that phagocytosis-related cellular functions are not altered in the context of CHB.

Predictors of response to tenofovir disoproxil fumarate plus peginterferon alfa-2a combination therapy for chronic hepatitis B. Aliment Pharmacol Ther 2016; 44:957-966.

Abstract
BACKGROUND In patients with chronic hepatitis B, tenofovir disoproxil fumarate (TDF) plus pegylated interferon (PEG-IFN) for 48-weeks results in higher rates of hepatitis B surface antigen (HBsAg) loss than either monotherapy. AIM To identify baseline and on-treatment factors associated with HBsAg loss at Week 72 and provide a model for predicting HBsAg loss in patients receiving combination therapy for 48 weeks. METHODS A secondary analysis of data from an open-label study where patients were randomised to TDF (300 mg/day, oral) plus PEG-IFN (PI, 180 μg/week, subcutaneous) for 48 weeks (TDF/PI-48w); TDF plus PEG-IFN for 16 weeks, TDF for 32 weeks (TDF/PI-16w+TDF-32w); TDF for 120 weeks (TDF-120w) or PEG-IFN for 48 weeks (PI-48w). Logistic regression methods were used to identify models that best predicted HBsAg loss at Week 72. RESULTS Rates of HBsAg loss at Week 72 were significantly higher in the TDF/PI-48w group (6.5%) than in the TDF/PI-16w+TDF-32w (0.5%), TDF-120w (0%) and PI-48w (2.2%) groups (P = 0.09). The only baseline factor associated with response was genotype A. HBsAg decline at Week 12 or 24 of treatment was associated with HBsAg loss at Week 72 (P < 0.001). HBsAg decline >3.5 log10 IU/mL at Week 24 in the TDF/PI-48w group resulted in a positive predictive value of 85% and a negative predictive value of 99% for HBsAg loss at Week 72. CONCLUSIONS HBsAg decline at Week 24 of TDF plus PEG-IFN combination therapy may identify patients who, after completing 48 weeks of treatment, have a better chance of achieving HBsAg loss at Week 72.

Abstract
We report the case of a 62-year-old man hospitalized in May 2015 for symptomatic heart failure. His medical history included two liver transplantations. The first liver transplantation was performed in 1999 for a mixed alcoholic and hepatitis C-related cirrhosis and the patient received the liver of another patient with Val30Met transthyretin amyloidosis using the domino technique. In 2008, he complained of neuropathic pains and an iatrogenic-acquired transthyretin amyloidosis was diagnosed. On cardiac evaluation, amyloidosis was suspected. In March 2010, a second liver transplantation was performed with a deceased donor without complication. In May 2015, a first episode of symptomatic heart failure occurred and cardiac amyloidosis was investigated by a multimodality evaluation. Electrocardiogram, cardiac biomarkers, echocardiography, and cardiac MRI were in favor of the diagnosis of amyloidosis, whereas 99m Tc-dicarboxypropane diphosphonate scintigraphy was not. Endomyocardial biopsy finally confirmed the positive diagnosis of iatrogenic-acquired cardiac amyloidosis. This case is, to the best of our knowledge, the first to report biopsy-proven cardiac amyloidosis induced by domino liver transplantation and progressing heart failure in spite of retransplantation. The diagnostic modalities are discussed. This case should alert physicians to the cardiac risk in domino liver transplanted patients.

Abstract
A retrospective analysis was conducted on 20 D(-) liver transplant (LT) recipients transfused with D(+) RBCs perioperatively and screened for RBC antibodies between 2 and 6 months later. None developed anti-D detectable by the indirect antiglobulin test. Two patients produced weak anti-D that reacted only with papain-treated RBCs at 10 and 11 days without any sign of immune haemolysis. Antibodies became quickly undetectable. These data suggest an unusual pattern of alloimmunization in LT recipients with rapid, weak and transient antibody response and support the safety of transfusing D(+) RBCs in most of D(-) patients during LT surgery.

Abstract
Monoclonal antibodies targeted against the immune checkpoint molecules CTLA-4 and PD-1 have recently obtained approval for the treatment of metastatic melanoma and advanced/refractory non small-cell lung cancers. Therefore, their use will not be limited anymore to selected hospitals involved in clinical trials. Indeed, they will be routinely prescribed in many cancer centers across the world. Besides their efficacy profile, these immune targeted agents also generate immune-related adverse events (irAEs). This new family of dysimmune toxicities remains largely unknown to the broad oncology community. Although severe irAEs remain rare (∼10% of cases under monotherapy), they can become life-threatening if not anticipated and managed appropriately. Over the last 5 years, Gustave Roussy has accumulated a significant experience in the prescription of immune checkpoint blockade (ICB) antibodies and the management of their toxicities. Together with the collaboration of Gustave Roussy's network of organ specialists with expertise in irAEs, we propose here some practical guidelines for the oncologist to help in the clinical care of patients under ICB immunotherapy.

Abstract
BACKGROUND Alisporivir (ALV) is an oral, host-targeting agent with pangenotypic anti-hepatitis C virus (HCV) activity and a high barrier to resistance. AIM To evaluate efficacy and safety of ALV plus peginterferon-α2a and ribavirin (PR) in treatment-naïve patients with chronic HCV genotype 1 infection. METHODS Double-blind, randomised, placebo-controlled, Phase 3 study evaluating ALV 600 mg once daily [response-guided therapy (RGT) for 24 or 48 weeks or 48 weeks fixed duration] or ALV 400 mg twice daily RGT with PR, compared to PR alone. Following a Food and Drug Administration partial clinical hold, ALV/placebo was discontinued and patients completed treatment with PR only. At that time, 87% of patients had received ≥12 weeks and 20% had received ≥24 weeks of ALV/PR triple therapy. RESULTS A total of 1081 patients were randomised (12% cirrhosis, 55% CT/TT IL28B). Addition of ALV to PR improved virological response in a dose-dependent fashion. Overall, sustained virological response (SVR12; primary endpoint) was 69% in all ALV groups vs. 53% in PR control. Highest SVR12 (90%) was achieved in patients treated with ALV 400 mg twice daily and PR for >24 weeks. Seven cases of pancreatitis were reported, with similar frequency between ALV/PR and PR control groups (0.6% vs. 0.8% respectively). Adverse events seen more frequently with ALV/PR than with PR alone were anaemia, thrombocytopenia, hyperbilirubinaemia and hypertension. CONCLUSIONS Alisporivir, especially the 400 mg twice daily regimen, increased efficacy of PR therapy in treatment-naïve patients with HCV genotype 1 infection. The mechanism of action and pangenotypic activity suggest that alisporivir could be useful in interferon-free combination regimens.

Abstract
BACKGROUND Few studies have investigated infections in human immunodeficiency virus (HIV)-infected liver transplant patients. The aim of this study was to describe the prevalence, time of onset, mortality of infectious complications, other than hepatitis C virus (HCV), and to identify risk factors for their development in a large single-center cohort of HIV-infected liver transplant patients. METHODS We studied 109 consecutive HIV-infected patients who underwent liver transplantation (LT) between 1999 and 2010 and followed until December 2012. RESULTS The median age was 44 years (interquartile range [IQR] 41-49), 82.6% were male, and the median follow-up was 45.7 months (IQR 14-65). The major indications for LT were HCV cirrhosis (61%) and hepatocellular carcinoma (19%). Forty patients (37%) developed at least 1 infection during the first year after LT. Twenty-eight (26%) patients had an episode of bacteremia. Five (4.6%) patients developed a cytomegalovirus infection. Fungal infections occurred in 5 (4.5%) patients. Four (3.6%) patients developed an HIV-related opportunistic infection. A total of 43 (39.4%) patients died during follow-up. Mortality related to infection occurred in 9 (7%) cases, and 20 (42.5%) patients died because of HCV recurrence. No patients died from opportunistic infections. Model for end-stage liver disease (MELD) score >17 was associated with a 2-fold higher risk (hazard ratio 1.96; 95% confidence interval 1.01-3.80) of developing infectious complications. CONCLUSIONS Infections are not a major cause of mortality after LT in HIV patients and opportunistic infections of acquired immunodeficiency syndrome are infrequent. A MELD score >17 increased the risk of developing post-LT infectious complications. Recurrence of HCV infection remains a major cause of mortality.

Abstract
UNLABELLED Acute-on-chronic liver failure (ACLF) is characterized by acute decompensation (AD) of cirrhosis, organ failure(s), and high 28-day mortality. We investigated whether assessments of patients at specific time points predicted their need for liver transplantation (LT) or the potential futility of their care. We assessed clinical courses of 388 patients who had ACLF at enrollment, from February through September 2011, or during early (28-day) follow-up of the prospective multicenter European Chronic Liver Failure (CLIF) ACLF in Cirrhosis study. We assessed ACLF grades at different time points to define disease resolution, improvement, worsening, or steady or fluctuating course. ACLF resolved or improved in 49.2%, had a steady or fluctuating course in 30.4%, and worsened in 20.4%. The 28-day transplant-free mortality was low-to-moderate (6%-18%) in patients with nonsevere early course (final no ACLF or ACLF-1) and high-to-very high (42%-92%) in those with severe early course (final ACLF-2 or -3) independently of initial grades. Independent predictors of course severity were CLIF Consortium ACLF score (CLIF-C ACLFs) and presence of liver failure (total bilirubin ≥12 mg/dL) at ACLF diagnosis. Eighty-one percent had their final ACLF grade at 1 week, resulting in accurate prediction of short- (28-day) and mid-term (90-day) mortality by ACLF grade at 3-7 days. Among patients that underwent early LT, 75% survived for at least 1 year. Among patients with ≥4 organ failures, or CLIF-C ACLFs >64 at days 3-7 days, and did not undergo LT, mortality was 100% by 28 days. CONCLUSIONS Assessment of ACLF patients at 3-7 days of the syndrome provides a tool to define the emergency of LT and a rational basis for intensive care discontinuation owing to futility.

Abstract
This study was a retrospective analysis of the European Liver Transplant Registry (ELTR) performed to compare long-term outcomes with prolonged-release tacrolimus versus tacrolimus BD in liver transplantation (January 2008-December 2012). Clinical efficacy measures included univariate and multivariate analyses of risk factors influencing graft and patient survival at 3 years posttransplant. Efficacy measures were repeated using propensity score-matching for baseline demographics. Patients with <1 month of follow-up were excluded from the analyses. In total, 4367 patients (prolonged-release tacrolimus: n = 528; BD: n = 3839) from 21 European centers were included. Tacrolimus BD treatment was significantly associated with inferior graft (risk ratio: 1.81; p = 0.001) and patient survival (risk ratio: 1.72; p = 0.004) in multivariate analyses. Similar analyses performed on the propensity score-matched patients confirmed the significant survival advantages observed in the prolonged-release tacrolimus- versus tacrolimus BD-treated group. This large retrospective analysis from the ELTR identified significant improvements in long-term graft and patient survival in patients treated with prolonged-release tacrolimus versus tacrolimus BD in primary liver transplant recipients over 3 years of treatment. However, as with any retrospective registry evaluation, there are a number of limitations that should be considered when interpreting these data.

Abstract
Since the early 1960s, several authors reported on the use of some experimental artificial liver devices in order to support patients with either acute liver failure (ALF) or end-stage chronic liver disease. In the 1980s, liver transplantation became an established real treatment replacing the whole liver with a major survival benefit. In the 1990s, the concept of albumin dialysis appeared as a new revolution in the concept of dialysis with the great capacity of removal of toxins, drugs and molecules strongly bound to albumin. Currently, three artificial liver support devices are available: The MARS®, the Prometheus® and the SPAD®. The most widely studied and used system is the MARS® that uses albumin dialysis to replace the detoxification function of the liver. MARS has shown in several uncontrolled studies and few randomized studies an improvement in the patient condition in terms of clinical symptoms (hepatic encephalopathy, pruritus, jaundice) and in liver and kidney biological parameters bringing these patients safely to liver transplantation. MARS® has shown for some patients with ALF (mainly paracetamol intoxication) an improvement of spontaneous or transplant free survival. The use of MARS in acute on chronic liver failure (ACLF) require further studies based on strict definition of the syndrome. The use of albumin dialysis technique, require the performance of multiple sessions of treatment or even (in situations of ALF) a continuous treatment in order to improve spontaneous recovery or bridge these patients to liver transplantation. The performance of these systems would need further improvement. Large randomized trials are still needed in both patients with ALF and ACLF to establish the indications, the timing and the real place of liver support therapies. Meanwhile, early use of these devices in patients with ALF and ACLF could be considered as an additional tool among others in the management of these patients in specialized liver units.

Effect of postmortem aging on marination performance of broiler breast pectoralis major categorized by color lightness. Poult Sci 2014; 93:3123-9.

Abstract
The objective was to evaluate the effect of postmortem aging on marination performance of early-deboned chicken breast fillets (pectoralis major) with different color lightness. Effects of marination on muscle shear force were also determined. Early-deboned (2 h postmortem) broiler butterfly fillets were visually selected based on their color lightness (pale, normal, and dark) from a commercial plant. The individual butterfly fillets were separated into left and right fillets. One of them was used for 6-h marination treatment and the other for 24-h marination treatment. Samples were marinated in a vacuum tumbler (-0.6 atm, 16 rpm, 20 min) with 20% wt/wt marinade yielding 0.75% NaCl and 0.45% phosphate in the final product. The effect of aging on salt-induced water gain by breast muscle was also measured using the swelling/centrifuging method. Marinade uptake, marinade retention, raw product yield, and cooked product yield were determined after tumbling, following storage for 24 and 48 h after marination and after cooking. Salt-induced water gain was greater (P < 0.05) in nonmarinated fillets at 24 h postmortem compared with 6 h postmortem. Compared with unmarinated fillets, marination enhanced finished product yield significantly (P < 0.05) regardless of postmortem aging and color lightness. Marinade retention and product yield were different (P < 0.05) in fillets categorized by L* (lightness) values. There were no differences (P > 0.05) between 2 postmortem aging times for marinade uptake, overall product yield, cooking loss, final cooked product yield, or meat shear force regardless of initial fillet L* values. However, marinade retention of 6-h samples was significantly better than 24-h samples (P < 0.05). These results demonstrate that with a targeted 15% marinade uptake, postmortem aging of 2-h deboned fillets before marination does not affect marinade uptake and product yield, but significantly affects marinade retention by boneless skinless chicken breast.

Abstract
BACKGROUND There is increasing need for rehabilitation in both cancer and palliative care. However, there are few validated outcome measures that are suitable for measuring functional performance in this population. The present study evaluated the validity, sensitivity and reliability of the Edmonton Functional Assessment Tool (EFAT2) within a UK palliative care setting. METHODS Eleven participants aged 65 years and over (mean age 76.5 ± 6.7 years) receiving rehabilitation in a palliative care inpatient setting were studied. Concurrent validity was assessed by comparing EFAT2 with the Barthel Index. Inter-rater reliability of EFAT2 was examined using a sample of four participants recruited from a cancer care ward. RESULTS A significant negative correlation was observed between the Barthel Index and EFAT2 (r = -0.765, p = 0.01) and both measures were found to be sensitive as determined by Cohen's effect size (EFAT2 = 0.60, Barthel Index = 0.72). High inter-rater reliability was noted for EFAT2 (ICC3, 1 = 0.85) and the agreement between scores was confirmed by Bland-Altman analysis. CONCLUSIONS EFAT2 showed concurrent validity with the Barthel Index when used to assess the effects of rehabilitation on participants with advanced cancer. The tool was sensitive to change and was found to be reliable when used by different raters. The findings indicate that EFAT2 might be an appropriate outcome measure to use within the palliative care setting. However, the feasibility of using EFAT2 needs to be explored and larger studies are required to confirm its reliability.

Abstract
This study determined the effects of extraction buffer pH and postmortem aging on the extraction of salt-soluble and water-soluble proteins from broiler pectoralis muscle. Deboned broiler breast fillets were collected at 4 h postmortem, packaged, and then stored at 4°C until 1, 5, or 8 d postmortem. After the designated aging period, salt-soluble and water-soluble protein extractions were performed using buffers at 7 different pH levels (pH 5.4, 6.4, 6.9, 7.2, 7.5, 8.0, 9.0). Protein concentrations of the extracts were measured and SDS-PAGE analysis was performed. Salt-soluble protein concentration increased (P < 0.0001) as buffer pH increased from pH 5.4 to 6.9 and then remained unchanged from pH 6.9 to 9.0. Water-soluble protein concentration increased (P < 0.0001) as buffer pH increased from pH 5.4 to 7.2 and then remained unchanged from pH 7.2 to 9.0. There was not a significant extraction buffer pH by aging treatment interaction for the total protein concentration of either the salt-soluble or water-soluble protein extracts. The protein concentrations of salt-soluble extracts were similar at both 1 and 8 d postmortem but lower (P < 0.0001) at 5 d postmortem. The protein concentrations of water-soluble extracts were similar at both 1 and 5 d postmortem, but higher (P < 0.0001) at 8 d. Both extraction buffer pH and postmortem aging influenced the SDS-PAGE protein profiles of salt-soluble and water-soluble protein extracts from breast muscles. Data demonstrate that postmortem aging and extraction buffer pH influence both the total amount and the composition of the myofibrillar and sarcoplasmic proteins that can be extracted from broiler breast fillets.

Abstract
Domino liver transplantation (DLT) has become an accepted procedure designed to address problems with organ limited supply. However, cases of acquired amyloid neuropathy are increasingly being recognized following this procedure. Until now, only one patient had undergone liver retransplantation and follow-up findings were not reported. We describe the case of a 72-year-old patient with partial recovery from acquired amyloid neuropathy following retransplantation with a deceased donor 7 years after DLT performed for end-stage liver disease. His clinical and paraclinical improvement is described, and the impact of this case on the indication for a domino procedure and the challenges linked to retransplantation are discussed.

Abstract
Immunization using live attenuated vaccines represents a contra-indication after solid organ transplantation (SOT): consequently, transplant candidates planning to travel in countries where yellow fever is endemic should be vaccinated prior to transplantation. The persistence of yellow fever vaccine-induced antibodies after transplantation has not been studied yet. We measured yellow-fever neutralizing antibodies in 53 SOT recipients vaccinated prior to transplantation (including 29 kidney recipients and 18 liver recipients). All but one (98%) had protective titers of antibodies after a median duration of 3 years (min.: 0.8, max.: 21) after transplantation. The median antibody level was 40 U/L (interquartile range: 40-80). For the 46 patients with a known or estimated date of vaccination, yellow-fever antibodies were still detectable after a median time of 13 years (range: 2-32 years) post-immunization. Our data suggest there is long-term persistence of antibodies to yellow fever in SOT recipients who have been vaccinated prior to transplantation.

Abstract
The aims of the study were to assess the risk of HHV8 transmission resulting from organ transplantation, and related morbidity in liver, heart and kidney transplant recipients. Donor and recipient serologies were screened between January 1, 2004 and January 1, 2005 using HHV8 indirect immunofluorescence latent assay (latent IFA) and indirect immunofluorescent lytic assay (lytic IFA). Recipients negative for latent IFA with a donor positive for at least one test were sequentially monitored for HHV8 viremia and underwent serological tests over a period of 2 years. The results showed that among 2354 donors, HHV8 seroprevalence was 9.9% (lytic IFA) and 4.4% (latent IFA). A total of 454 organ recipients (281 renal, 116 liver and 57 heart) were monitored over a 2-year period. Seroconversion was observed in 12 patients (cumulative incidence 28%) whose donor had positive latent IFA and in 36 patients (cumulative incidence 29%) whose donors were positive only for lytic IFA, without differences across types of transplants. Positive HHV8 viremia was detected in only 4 out of 89 liver transplant recipients during follow-up and not in recipients of other types of transplant. Two liver transplant recipients and one kidney transplant recipient developed KS. In conclusion, although HHV8 transmission is a frequent event after organ transplantation, HHV8-related morbidity is rather rare but can be life threatening. Donor screening is advisable for monitoring HHV8 seronegative liver transplant recipients.

Abstract
BACKGROUND AND OBJECTIVES During the 1918, pandemic blood components were successfully used to treat severe influenza pneumonia. A Proof of Principle trial investigating the clinical benefit of convalescent plasma was proposed in the 2009 H1N1v epidemic with the aim of screening donors for high titre antibody in order to stockpile plasma packs to be used for treatment for severe pneumonia. MATERIALS AND METHODS Serum samples were collected from donors. IgG antibody capture format enzyme-linked immunoassays using recombinant proteins (GACELISAs) were compared with microneutralization (MN) and haemagglutination inhibition (HAI). The influence of age and history of influenza-like illness (ILI) on the detection of high titre antibody was examined. RESULTS 1598 unselected donor sera collected in October and December 2009 were tested by HAI. The HAI and demographic data defined a possible strategy for selective donor screening. One of the GACELISAs was highly specific for recent infection but showed lower sensitivity than HAI. CONCLUSIONS During the 2009 pandemic screening 17- to 30-year-old donors by HAI delivered around 10% with high antibody levels. The ELISA using a short recombinant H1N1v HA detected fewer reactives but was more specific for high titre antibody (≥1:256). Screening strategies are proposed based on using HAI on serum or GACELISA on plasma.

Abstract
BACKGROUND The clinical presentation of hepatic artery thrombosis (HAT) post-liver transplantation (LT) varies considerably. Doppler ultrasonography (Doppler US) is the first line investigation, with a diagnostic sensitivity for HAT as high as 92%. Because indocyanine green (ICG) elimination from the blood depends among other factors on the hepatic blood flow, we hypothesized that plasma disappearance rate of indocyanine green (PDR-ICG) can be influenced by the flow in the hepatic artery. Thus, we evaluated the role of PDR-ICG measurement in HAT diagnosis in post-LT patients. PATIENTS AND METHODS Fourteen liver transplant patients with no visible flow in the hepatic artery (Doppler US) were identified. Of the 14, seven patients had HAT confirmed by CT-angiography. The PDR-ICG measurement, an investigation routinely used in our center, was performed in all 14 patients. RESULTS The PDR-ICG in patients with HAT was significantly lower than in patients without HAT (5.8 ± 4.3 vs. 23.8 ± 7.4%/min, p= 0.0009). In patients with HAT, after the revascularization, the PDR-ICG value increased (5.8 ± 4.3 vs. 15.6 ± 3.5%/min, p = 0.006). CONCLUSION The ICG elimination may be an adjunct diagnostic tool in the management of patients with suspected HAT following LT.
