We previously reported data from 103 patients with hematologic malignancies (median age 54 years) who received peripheral blood stem cell (PBSC) grafts from HLA-matched unrelated donors after nonmycloablative conditioning and were given postgrafting immunosuppression consisting of mycophenolate mofetil (MMF; administered from day 0 until day + 40 with taper through day + 96) and cyclosporine (CSP; given from day -3 to day + 100, with taper through day 180) (historical patients). The incidences of grade II-IV acute and extensive chronic graft-versus-host disease (aGVHD, cGVHD) were 52% and 49%, respectively, and the 1-year probabilities of relapse, nonrelapse mortality (NRM), and progression-free survival (PFS) were 26%, 18%, and 56%, respectively. Here, we treated 71 patients with hematologic malignancies (median age 56 years) with unrelated PBSC grafts and investigated whether postgrafting immunosuppression with an extended course of NMF, given at full dosing until day + 150 and then tapered through day + 180, and a shortened course of CSP, through day + 80, would promote tolerance induction and reduce the incidence of GVHD (current patients). We observed 77% grade ll-1V aGVHD and 45% extensive cGVHD (P =.03, and P =.43, respectively, in current compared to historical patients). The 1-year probabilities of relapse, NRM, and PFS were 23%, 29%, and 47%, respectively (P =.89, P =.02, and P =.08 compared to the historical patients). We conclude that postgrafting immunosuppression with extended MMF and shortened CSP failed to decrease the incidence of GVHD among unrelated PBSC recipients given nonmyeloablative conditioning.

Extended spectrum beta-lactamases (ESBL)-producing Escherichia coli have emerged worldwide in animal husbandry and they were reported from different ecosystems. The purpose of this study was firstly, to investigate the presence of ESBL-producing E. coli in the gastrointestinal (GIT) and reproductive (RT) tracts of broiler breeding roosters, and secondly to study the impact of an ESBL-producing E. coli on artificially infected semen. A total of seventeen ESBL-producing E. coli strains were isolated from the gastrointestinal and reproductive tracts of nine broiler breeding roosters. All isolates were identified to the species level by API 20E system and MALDI-TOF, serotyped, and genetically characterized for ESBL production. Semen was artificially infected with E. coli ATCC25922 or with an ESBL-producing E. coli strain recovered from the reproductive tract. A computer aided semen analyzer (CASA) was used to compare different spermatozoa motility parameters in each sample. All ESBL-producing E. coli isolates could not be typed with the currently used sera and they were harboring a blaCTX-M gene alone or in combination with a blaTEM gene. The semen quality was notably less affected in samples infected with ESBL-producing E. coli strain compared to the control and sample infected with E. coli ATCC25922. The present study revealed that ESBL-producing E. coli can be isolated from both reproductive and digestive tracts of broiler breeding roosters. Contamination of the reproductive tract with ESBL-producing E. coli could lead to contamination of semen and could be an important factor in the dissemination of ESBL-producing E. coli in poultry.

A thermodynamic description of transient heat conduction at small length and timescales is proposed. It is based on extended irreversible thermodynamics and the main feature of this formalism is to elevate the heat flux vector to the status of independent variable at the same level as the classical variable, the temperature. The present model assumes the coexistence of two kinds of heat carriers: diffusive and ballistic phonons. The behaviour of the diffusive phonons is governed by a Cattaneo-type equation to take into account the high-frequency phenomena generally present at nanoscales. To include non-local effects that are dominant in nanostructures, it is assumed that the ballistic carriers are obeying a Guyer–Krumhansl relation. The model is applied to the problem of transient heat conduction through a thin nanofilm. The numerical results are compared with those provided by Fourier, Cattaneo and other recent models.

BACKGROUND: Thymectomy is considered as an effective therapeutic option for patients with myasthenia gravis (MG). This study reports the experience of our centre's investigation into the efficacy and the safety of the procedure and the influence of different pre-operative factors on the surgical outcome. METHODS: A retrospective chart review/interview was made of 19 consecutive patients who underwent extended transsternal thymectomy for MG from 1992 to 2003. The severity of the disease was determined according to the Osserman Classification. Efficacy was measured by determining the change in clinical status, the rate of remission during follow-up, and the reduction in medication requirements after thymectomy. Complete remission (CR) was defined as asymptomatic off medication for 6 months. The CR rate was calculated using the Kaplan-Meyer method. RESULTS: The mean age of the patients at surgery was 34 years (range, 9-63) and 78.9% were female. Mean length of follow up was 86 months (range, 24-163). The overall complication rate was 10.6% (1 episode of atrial fibrillation and a left recurrent laryngeal nerve palsy that resolved after the first postoperative month). There was no operative mortality. The mean hospital stay was 9.4 days (range, 5-23). The crude CR rate was 32% (n = 6). The Kaplan-Meier estimate of CR was 42% at 6 years. Age, gender, duration of symptoms, thymic histology, Osserman stage and the presence of thymoma were not identified as prognostic variables. The average daily dose of Medrol and Mestinon decreased significantly between the pre-operative period and the last follow-up (Medrol, p = 0.0081; Mestinon, p = 0.0013). CONCLUSIONS: Transsternal thymectomy for MG is safe and effective. It benefits patients with MG at all stages. Patients with thymoma are not associated with poorer remission rates. Complete responses are durable, as the CR rate remains stable over time. [less ▲]

Abstract Extended-spectrum β-lactamase (ESBL)-produc- ing Enterobacteriaceae have been described worldwide, but there are few reports on the carriage of these bacteria in Cameroon. In order to investigate the types of ESBLs and to analyse some risk factors associated with ESBL carriage, faecal samples were collected between 3 January and 3 April 2009 from hospitalised patients at Yaounde Central Hospital and at two hospitals in Ngaoundere, Cameroon. Enterobacterial isolates resistant to third-generation cepha- losporins were screened for ESBL production using the double-disk synergy test. Polymerase chain reaction (PCR) and DNA sequencing were performed in order to find out the different types of ESBL genes in presumptive ESBL- positive isolates. During the study period, a total of 121 different patients were screened for ESBL carriage. The prevalence among these patients whose faecal samples were found to contain ESBL-producers was 55.3 % (67/121). According to a univariate analysis, hospitalisation during the previous year was found to be associated with ESBL carriage. Of the 71 bacteria isolated, Escherichia coli was predominant and represented 48 % of all isolates. ESBL characterisation revealed two types of ESBLs, CTX-M-15 (96 %) and SHV-12 (4 %). The present study emphasises the importance of screening for ESBLs in laboratories in Afri- can countries. The monitoring and detection of ESBL- producing bacteria are important in the setting up of appro- priate treatment of patients and to ensure effective infection control efforts. [less ▲]

Organisms producing extended-spectrum beta-lactamases (ESBLs) have been reported in many countries, but there is no information on the prevalence of ESBL-producing members of the family Enterobacteriaceae in Cameroon. A total of 259 Enterobacteriaceae strains were isolated between 1995 and 1998 from patients at the Yaounde Central Hospital in Cameroon. Enterobacterial isolates resistant to extended-spectrum cephalosporin and monobactam were screened for ESBL production by the double-disk (DD) synergy test. Thirty-one (12%) of these Enterobacteriaceae strains were shown to be positive by the DD synergy test, suggesting the presence of ESBLs. Resistance to oxyimino-cephalosporins and monobactams of 12 (38.7%) of the 31 strains-i.e., 6 Klebsiella pneumoniae, 4 Escherichia coli, 1 Citrobacter freundii, and 1 Enterobacter cloacae strain-was transferred to E. coli HK-225 by conjugation. Resistance to gentamicin, gentamicin plus trimethoprim-sulfamethoxazole, or trimethoprim-sulfamethoxazole was cotransferred into 6, 2, and 1 of these transconjugants, respectively. All 12 transconjugants were resistant to amoxicillin, piperacillin, all of the cephalosporins, and aztreonam but remained susceptible to cefoxitin and imipenem. Crude extracts of beta-lactamase-producing transconjugants were able to reduce the diameters of inhibition zones around disks containing penicillins, narrow- to expanded-spectrum cephalosporins or monobactams when tested against a fully susceptible E. coli strain but had no effect on such zones around cefoxitin, imipenem, and amoxicillin-clavulanate disks. The beta-lactamases produced by the 12 tranconjugants turned out to be SHV-12 by DNA sequencing. Therefore, the ESBL SHV-12 is described for the first time in Cameroon. [less ▲]

BACKGROUND: There is evident benefit in terms of reduced aneurysm related mortality from screening programmes of abdominal aortic aneurysm (AAA) in men aged 65 and more. Recent studies in UK and Sweden have shown a decline of the prevalence of AAA in the general population. Current screening policies (e.g. men aged 65-74 years) however do not account for ageing and increased life expectancy of western populations. This study investigated AAA detection by extending the target population to older age groups (75-85 years). METHODS: AAA screening was conducted in the County of Chaudfontaine (Liege, Belgium) on the population of elderly (N=3,054). The participation rate was 36%. The 1,101 participants (722 men aged 65-85 and 379 women aged 74-85 years) were examined by ultrasound (US) scan. AAA was defined as an infrarenal aortic outer-outer diameter of at least 3 cm. Demographics, clinical parameters and risk factors were also recorded. AAA prevalence was estimated and patients with and without AAA were compared by logistic regression. RESULTS: The overall AAA prevalence was 3.6% (n=40). In female participants, AAA prevalence was low (1.3%). In men, it amounted 2.7% in the 65-74 age group but rose to 7.3% in the age-extended group (75-85 years). Further in addition to age, height, current smoking, history of coronary artery disease, hypercholesterolemia, peripheral artery disease of the lower limbs and varicose veins were significantly associated with the presence of AAA. CONCLUSION: These preliminary findings, based on a representative sample of the elderly population of the Liege region, support the idea that current AAA screening policies should be updated to cover an increasingly ageing population. The presence of varicose veins as a potential risk factor for AAA should also be considered during screening. [less ▲]

Through a series of clinical studies, this thesis aims to clarify the contribution of donation after cardiac death (DCD) to the deceased donor (DD) pool and results of kidney and liver transplantation coming from this donor source in Liège and Belgium. Additionally, an adapted DCD Maastricht classification is also discussed. Chapters 2.1 and 2.2 summarize the DCD procurement and transplant activity in Liège and Belgium from 2000 to 2009 with an update on data up to 2011. In Liège, DCD really contributes to the DD pool and boosts the transplant activity of the center in both kidneys and livers by on average 30%. By contrast, the steady rise in DCD activity in Belgium does not lead to major increase in the DD donation and transplantation. In other words, some kind of donor-type redistribution within the DD pool might occur. Chapters 2.2, 3.1, and 3.2 discuss the results of kidney transplantation (KT) from DCD. We demonstrate that Liège‟s experience is comparable to the national level in Belgium and does not differ from the general results in the world with regard to early graft dysfunction, medium-term graft function, graft and patient survival. The excellent results of DCD-KT are attributed to the relatively short warm and cold ischemia, favorable donor factors, and the role of hypothermic machine perfusion (in Belgian series). Chapters 4.1, and 4.2 discuss the results of liver transplantation (LT) from DCD. Liège‟s results are encouraging and apparently as good as those from donation-after-brain-death LT because of short warm and cold ischemia times. Belgian results show an increased incidence of primary non-function and ischemic cholangiopathy which is in agreement with previously published data. Chapter 5 proposes an adapted DCD Maastricht classification which maintains the original categories 1 to 4 that are now well-known and widely accepted, and adds a fifth category, so-called „DCD after euthanasia‟. Each category is divided into two or three sub-categories: sub-category A is linked to longer warm ischemia (and worse results) than sub-category B; and B versus C, respectively. In addition, sub-categories A (2A, 3A, 4A, and 5A) are mostly linked to DCD processes occurring in the ICU, which helps to understand and memorize this classification. By keeping the original skeleton of the 1995 Maastricht classification, room is left to add new sub-categories in the future, if deemed clinically relevant. [less ▲]
