ABSTRACT

Regulated-on-activation, normal T cell expressed and secreted (also called RANTES, CCL5 or R/C) is a chemotactic cytokine that plays a key role in recruiting immune cells to inflammatory sites. R/C is involved in the pathogenesis of many systemic immune-mediated diseases (SIDs) and is upregulated in fatty-degenerative osteolysis jawbone (FDOJ) cavitations. Surgical cleaning of degenerative areas reduces the source of chronic R/C but might not be sufficient to re-establish the altered immunological patterns. The aim of the present study was to collect clinical data from patients suffering from sids who underwent dental surgery of FDOJ areas (n=46), by measuring R/C serum levels at the first visit (V0) prior to surgery, and at the second visit (V1). The majority of patients (n=41) were treated one month with ultra-low dose RANTES (27CH), a medicine used in micro-immunotherapy, while five patients were not. Mean and standard deviation of R/C serum levels at V0 in treated and untreated patients were respectively 48.5±25.8ng/ml and 42.48±22.22ng/ ml. Untreated patients had a tendency towards higher R/C levels at V1 (68.36±30.7ng/ml; p=0.062), while an opposite tendency was observed in treated patients (40.9±20.3ng/ml; p=0.129). Investigators observed that a cut-off set at 40ng/ml at V0 seemed to be predictive of the efficacy of the dental surgery/treatment (p=0.0013, n=26) and that gender could influence R/C levels and patient's responsiveness. The Authors, being aware that this is a preliminary follow-up, wanted to lay the basis for forthcoming studies, in which a larger cohort of patients and well-defined inclusion/exclusion criteria will be established.

ABSTRACT

A survey of state mental health agencies found that a majority have no specific policy or procedure regarding how to provide mental health services to persons who are deaf or who are deaf-blind. Agency representatives report that staff lack knowledge of how to provide mental health services to persons who are deaf-blind and the agencies lack qualified interpreters. They recommend training for social workers and counselors to address best practices in working with people who are deaf-blind concerning communication methods and strategies, physical interaction, cultural issues, everyday life, sensory deprivation, ethics, use of an interpreter, and other general issues.

ABSTRACT

This report describes the clinical, laboratory and ultrasonographic findings in a Simmental heifer with a ceco-cecal intussusception. The general condition of the heifer was moderately reduced and it showed mild colic signs. Physical examination revealed a firm longish mass visible and palpable in the right flank. Findings upon rectal examination, fecal output und defecation were normal. Ultrasound examination of the mass revealed features typical for an intussusception. Based on the slow development of symptoms, normal fecal output and ultrasonography findings, a ceco-cecal intussusception was diagnosed. Right flank laparatomy was performed under general anaesthesia, and an end-to-side anastomosis between the jejunum and the spiral colon was made after resection of the intussuscepted intestines. Recovery was uneventful.

ABSTRACT

STUDY QUESTION: What is the effect of a legal limitation of the number of embryos that can be transferred in an assisted reproductive technology (ART) cycle on the multiple delivery rate? SUMMARY ANSWER: The Belgian national register shows that the introduction of reimbursement of ART laboratory costs in July 2003, and the imposition of a legal limitation of the number of embryos transferred in the same year, were associated with a >50% reduction of the multiple pregnancy rate from 27 to 11% between 2003 and the last assessment in 2010, without any reduction of the pregnancy rate per cycle. WHAT IS KNOWN ALREADY: Individual Belgian IVF centres have published their results since the implementation of the law, and these show a decrease in the multiple pregnancy rate on a centre by centre basis. However, the overall national picture remains unpublished. STUDY DESIGN, SIZE, DURATION: Cohort study from 1990 to 2010 of all ART cycles in Belgium (2685 cycles in 1990 evolving to 19 110 cycles in 2010), with a retrospective analysis from 1990 to 2000 and prospective online data collection since 2001. PARTICIPANTS/MATERIALS, SETTING, METHODS: Registration evolved from paper written reports per centre to a compulsory online registration of all ART cycles. From 2001 up to mid-2009, data were collected from Excel spread sheets or MS Access files into an MS Access database. Since mid-2009, data collection is done via a remote and secured web-based system (www.belrap.be) where centres can upload their data and get immediate feedback about missing data, errors and inconsistencies. MAIN RESULTS AND THE ROLE OF CHANCE: National Belgian registration data show that reimbursement of IVF laboratory costs in July 2003, coupled to a legal limitation in the number of embryos transferred in utero, were associated with a 50% reduction of the multiple pregnancy rate from 27 to 11% without reduction of the pregnancy rate per cycle, and with an increase in the number of fresh and frozen ART cycles due to improved access to treatment. LIMITATIONS, REASONS FOR CAUTION: There is potential underreporting of complications of ART treatment, pregnancy outcome and neonatal health. WIDER IMPLICATIONS OF THE FINDINGS: Over the 20 years of registration, the pregnancy rate has remained constant, despite the reduction in the number of embryos transferred, optimization of laboratory procedures and stimulation protocols, introduction of quality systems and implementation of the EU Tissue Directive over the period 2004-2010. STUDY FUNDING/COMPETING INTEREST(S): No external funding was sought for this study. None of the authors has any conflict of interest to declare.

ABSTRACT

INTRODUCTION: We had for aim to describe control and investigation of an outbreak caused by a strain of Extended spectrum beta-lactamase producing Klebsiella pneumoniae in intensive care units of the Brest teaching hospital. PATIENTS AND METHOD: The case definition was a patient infected by or carrying the epidemic strain. Control measures and investigations are presented. A case-control study was conducted in the surgical intensive care unit. Each case was matched with two controls based on admission times in the unit. The study focused on diagnostic and therapeutic procedures, and potential contacts with healthcare workers, in this context of cross transmission. RESULTS: Between February and May 2011, nine cases were reported in the surgical ICU and two in the medical ICU. Eighteen controls were matched with the nine surgical ICU cases. Several factors were found to be statistically associated with infection or colonization by the epidemic strain: the surgical block in which patients had been operated and the ward of first hospitalization; the number of trans-esophageal and trans-thoracic echocardiographies, of central venous catheter insertions, and of surgical operations; intubation. The total number of invasive procedures was also found to be statistically higher among cases. CONCLUSION: This study identified factors associated with colonization or infection by the epidemic strain. These factors might have been involved in the transmission tree, and be vulnerable elements for the prevention of nosocomial infections and colonisations, and their epidemic spread.

ABSTRACT

Serum samples from 142 calves and their dams were analyzed for gammaglobulins (gammaG, calves) and selenium concentrations (Se, calves and dams). A questionnaire provided information about birth and colostrum management. The calves and their dams were distributed into two groups according the calves' gammaG concentration (< 10 and >= 10 g/L), Se concentrations were compared between groups. The correlation between gammaG and Se concentrations in the calves and their dams was analyzed. Risk factors for failure of passive transfer and Se deficiency were assessed based on the questionnaire. The gammaG concentration of 42.9 % of the calves was < 10 g/L (median: 10.9). Calves showed significantly higher gammaG values after optimized colostrum administration than calves with suboptimal colostrum administration (p < 0.004). The median Se concentration was 26.8 and 36.5 µg/L for the calves and dams, respectively. A high correlation was observed between the Se concentration of the dam and her calf (r = 0.72, p < 0.001). The calves' Se and gammaG concentrations were not significantly correlated. These results demonstrate that further efforts toward better information of farmers regarding colostrum management and Se supply are warranted.

ABSTRACT

BACKGROUND: Pre-operative skin preparation, aimed at reducing the endogenous microbial flora, is one of the main preventive measures employed to decrease the likelihood of surgical site infection. National recommendations on pre-operative management of infection risks were issued in France in 2004. AIM: To assess compliance with the French national guidelines for pre-operative skin preparation in 2007. METHODS: A prospective audit was undertaken in French hospitals through interviews with patients and staff, and observation of professional practice. Compliance with five major criteria selected from the guidelines was studied: patient information, pre-operative showering, pre-operative hair removal, surgical site disinfection and documentation of these procedures. FINDINGS: Data for 41,188 patients from all specialties at 609 facilities were analysed. Patients were issued with information about pre-operative showering in 88.2% of cases [95% confidence interval (CI) 87.9-88.5]. The recommended procedure for pre-operative showering, including hairwashing, with an antiseptic skin wash solution was followed by 70.3% of patients (95% CI 69.9-70.8); this percentage was higher when patients had received appropriate information (P < 0.001). Compliance with hair removal procedures was observed in 91.5% of cases (95% CI 91.2-91.8), and compliance with surgical site disinfection recommendations was observed in 25,529 cases (62.0%, 95% CI 61.5-62.5). The following documentary evidence was found: information given to patient, 35.6% of cases; pre-operative surgical hygiene, 82.3% of cases; and pre-operative site disinfection, 71.7% of cases. CONCLUSION: The essential content of the French guidelines seems to be understood, but reminders need to be issued. Some recommendations may need to be adapted for certain specialties.

ABSTRACT

In France, although there are 445,000 beds in nursing homes (NHs) for elderly people, no studies on the burden of infections in NHs have been published. We sought to estimate the prevalence of infection among the residents and to assess the extent to which infections were associated with the residents' risk factors. We performed a nationwide, multicentre, cross-sectional, clustered period prevalence survey over five one-month periods. Cases of infection were classified as definite or, in the absence of laboratory confirmation, as probable. A total of 44,869 residents in 578 volunteer facilities were enrolled in the survey. The overall prevalence rate of infections was 11.23% [95% confidence interval (CI): 10.50-11.97] and differed significantly (P<0.001) across survey periods (the time of the year the survey was carried out). The rate of definite cases was 4.60% (95% CI: 4.04-5.54) and the rate of probable cases was 6.63% (95% CI: 5.77-7.98). Respiratory tract infections were the most frequent and accounted for 41% of all infections. Infections were significantly associated with age, length of stay, full disability, urinary device, bedsores and the survey period. Only prevention programmes may reduce the impact of infections on this frail population.

ABSTRACT

A nationwide survey was performed using a two-round web-based Delphi procedure to develop a set of consensus guidelines for preventing infections among residents in nursing homes (NHs). The research group was led by an investigative group of six specialists. Research analysts conducted a literature search and review of practice guidelines, systematic reviews and articles or abstracts published in English and French on the topic of infection prevention. The literature search was examined by 23 specialists (who compiled a preliminary list of 301 recommendations). Using a Delphi survey online instrument, 81 experts from all relevant medical specialties in the fields of infection prevention and control and geriatrics rated their agreement with each of the recommendations using a nine-point scale (1 = strongly disagree, 9 = strongly agree). During the second round, 79 participants received anonymous feedback from the first round and assessed a narrowed list of 130 recommendations. Recommendations were retained and classified according to the overall median score and ratings percentages by stakeholders. A total of 79 raters rated ≥ 10% of items, and 264 recommendations were retained and rated as follows: 240 items reached consensus, 24 items reached near consensus, 37 items were discarded and one recommendation was deleted. Many infections, though not all, can be prevented in the frail elderly. Thus, these guidelines should be adopted by each healthcare professional and facility to implement routine infection control procedures.

ABSTRACT

OBJECTIVES: The study objectives were to describe the investigation and management of an imipenem-resistant Acinetobacter baumannii outbreak that occurred in the 15-bed ICU of a tertiary care teaching hospital (Brest, France), during the summer 2008. PATIENTS AND METHODS: Patients harboring an imipenem-resistant A. baumannii strain were defined as case patients. We described case occurrence and steps taken to control the outbreak: contact isolation, reinforcement of hygiene procedures, unit shutdown decision, unit disinfection, and reopening. We also made a case control study and a cost analysis of the outbreak management. RESULTS: During a 10-day period, five patients were positive for a single clone of imipenem-resistant oxa-23 A. baumannii. Four patients presented with ventilation-acquired pneumonia and one was asymptomatic. The first two patients died one day after the first swab which led to the identification of A. baumannii. No additional case was noted in the ICU or in other hospital units after deciding to close the ICU. The cost of outbreak management was estimated at 264,553 euros. The case control study identified several factors associated with infection or colonization: length of stay in the ICU, chronic respiratory disease, number of previous antibiotic classes used, duration of ventilation, prone position, echocardiography, and presence of a nasogastric tube. CONCLUSION: This outbreak occurred during the summer period requiring the shutdown of the ICU and inducing a considerable cost. Rapid reactions of the ICU staff during the outbreak enabled to limit the epidemic.

ABSTRACT

BACKGROUND: Because of a lack of efficacy of influenza vaccination in elderly population, there are still numerous outbreaks in geriatric health care settings. The health care workers (HCW) flu vaccination is known to get herd immunity and decrease the impact of influenza in elderly population living in geriatric health care settings. However, the rates of vaccinated HCWs are still low in France. The French Geriatric Infection Risk Institute (ORIG) performed the VESTA study, a three-phase multicentre to identify factors limiting vaccination in HCWs, and to develop and implement active programs promoting HCWs influenza vaccination. OBJECTIVES: To implement multicenter programs to enhance HCW influenza vaccination. DESIGN: It was a cluster randomised interventional studies. SETTING: 43 geriatric health care settings (GHCSs), long term care and rehabilitation care settings in France. PARTICIPANTS: 1814 Health care workers from 20 GHCSs in the interventional group and 2,435 health care workers in 23 GHCSs in the control group. INTERVENTION: After the failure of a first educational program giving scientific information and. tested during the 2005-06 flu season in 43 HCSs, a second program was designed with the help of marketing experts, one year after Program 1. The objectives were to involve HCWs in the creation of "safety zones", and to give personal satisfaction. Program 2 was tested during the 2006-07 season. 20 of the 24 HCSs from the Program 1 cluster were included in the Program 2 cluster (1,814 HCWs), and 16 of the 19 HCSs from the Control 1 cluster, plus 7 new HCSs with interest in participating, were included in the Control 2 cluster (23 HCSs; 2,435 HCWs). MEASUREMENTS: The efficacy of each program was assessed by calculating and comparing the percentage of vaccinated HCWs, from all HCSs taken together, in the program and control clusters. RESULTS: Program 1 failed to increase the HCW vaccination coverage rate (VCR) (Program 1: 34%; Control 1: 32%; p > 0.05),). Program 2 increased the VCR in HCWs (Program 2: 44%; Control 2: 27%; Chi2 test, p < 0.001) regardless their occupational group but only in the non previous vaccinated subgroup. CONCLUSIONS: In geriatric health care centres in France, an active multicenter program giving personal satisfaction and taking into account the profile of non-vaccinated HCWs was more effective in promoting flu vaccination than a scientifically factual information program. HCW involvement is required in program implementation in order to avoid rejection of top-down information.

ABSTRACT

UNLABELLED: The fight against healthcare-associated infections is based on preventive measures of multidrug resistant bacteria diffusion. Hand hygiene is the simplest and the most effective preventive measure to reduce cross-transmission of infectious agents. Hydroalcoholic solutions for hand hygiene was recently introduced in the University Hospital of Brest (France). The aims of the study were: to describe the epidemiology of healthcare-associated infections due to methicillin-resistant Staphylococcus aureus (MRSA); to determine the annual consumptions of antistaphylococcal antibiotics; and to discuss the relation between consumption of antiseptic products or antibiotics and the epidemiology of MRSA. METHODS: A retrospective epidemiological and pharmaco-epidemiological study was realized from January 2004 to December 2007 in the University Hospital of Brest (France). It allowed to bring to light the cases of healthcare-associated infections due to MRSA and to quantify the consumptions of hang hygiene products and antistaphylococcal antibiotics. RESULTS: this retrospective study showed a decrease of healthcare-associated infections due to MRSA and an increase of the consumption of hydroalcoholic solutions. Antistaphylococcal resistance rates also decreased in a context of fall of the global antibiotics consumption in the hospital.

ABSTRACT

A 2-year-old Red Holstein cow was presented with uterine torsion at 235 days of pregnancy. The fetus extracted by cesarean section had weak vital signs and marked abdominal distention. An edematous pouch that contained tubular structures with peristaltic activity was associated with the umbilical cord. Because of poor prognosis, both dam and fetus were euthanized. At necropsy, the fetus had severe distention of the forestomachs, abomasum, and proximal small intestine; absence of distal small intestine, cecum, and proximal colon; atresia of the 2 blind ends of the intestine; and atrophy of distal colon and rectum. The tubular structures associated with the umbilical cord were identified as the segments of intestine that were absent in the fetus. Intestinal atresia combined with ectopia may be caused by local ischemia during temporary herniation and rotation of the fetal gut into the extraembryonic coelom. The close connection between ectopic intestine and amniotic sheath of the umbilical cord in this case may have facilitated vascularization and allowed development and viability of the ectopic intestine.

ABSTRACT

OBJECTIVES: The aim of this study is to evaluate the quality of disinfection of endoscopes at Brest hospital over a period from 2007 to 2009. PATIENTS AND METHODS: Retrospective study of microbiological investigations of endoscopes done at Brest hospital from 2007 to 2009. The interpretation of the microbiological investigations is based on the recommendations of the Comité technique national des infections nosocomiales et infections liées aux soins (CTINILS) of 2007. RESULTS: Most of the controls realized over the period deal with gastroenterological endoscopes (63.4 %) and bronchial endoscopes (21.8 %). Most of the controls (66.8 %) are conformed to the target level. Only 26.7 % of the controls get the level of action. Globally, the rate of level of action significantly increases (p=0.004) from 2007 (21.2 %) to 2009 (35.6 %). This increase is relatively important in gastroenterology endoscopy (46.8 % in 2009 versus 24.1 % in 2007) whereas the rate decreases in bronchial endoscopy (14.8 % in 2009 versus 25.9 % in 2007). In gastroenterological endoscopy, rates vary with the type of endoscopes and the context of controls, but there is no significant difference between manual disinfection and automated disinfection. The most frequent germ found in gastroenterological and bronchial endoscopies is Pseudomonas aeruginosa. CONCLUSION: Our results show that it is very difficult to insure a perfect disinfection of endoscopes. Difficulties met are certainly related with the complexity of the endoscopes and of the techniques of disinfection. Infections of patients are very infrequent in endoscopy, which takes the question of the pertinence of the threshold used for microbiological investigations.

ABSTRACT

Vitrification with the use of "Open" carrier devices (Cryoloop, cryotop, cryoleaf, Vitriplug) which allowed the contact with liquid nitrogen has become a more popular way to achieve cooling rate superior to 20,000 °C/min. Even though the question of contamination with liquid nitrogen during ultra-rapid cooling and storage remain debatable with the use of "open" devices, it is important to revise the carrier system in a way, which minimizes the risk of contamination. According to the EU tissues and cells directive, it is advisable that the cooling and storage should be carried out in embryo carrier devices ensuring complete separation of the embryos from liquid nitrogen in a way, which minimizes the risk of contamination. The consequence of a reduction in the cooling rate resulting from the heat-insulating barrier of aseptic devices has to be counteracted by gradually increasing intracellular concentrations of cryoprotectants without inducing a toxic effect. We developed an aseptic vitrification method of vitrification for MII oocytes and embryos at different stage of development using the "VitriSafe" as "closed" carrier device.

ABSTRACT

The use of high levels of cryoprotectants (CPs) in solutions applied to vitrify oocytes or embryos is an argument to still prefer slow freezing procedure. Is it a justified argument? Out of three studies using mice zygotes we may assume that (i) the intracellular concentration of CPs is far lower than the one in the vitrification solutions, (ii) the intracellular concentration of CPs in the vitrified zygote is in contrary to the common beliefs even lower than the one observed after a slow freezing procedure, (iii) survival after slow freezing reflects the presence of an intracellular vitrified state in these cells.

ABSTRACT

BACKGROUND: Cross-border reproductive care indicates the cross-border movements made by patients to obtain infertility treatment they cannot obtain at home. The problem at present is that empirical data on the extent of the phenomenon are lacking. This article presents the data on infertility patients going to Belgium for treatment. METHODS: A survey was conducted among the centres for reproductive medicine that are allowed to handle oocytes and create embryos (B-centres). Data were collected on the nationality of patients and the type of treatment for which they attended during the period 2000-2007. RESULTS: Sixteen of 18 centres responded to the questionnaire. The flow of foreign patients has stabilized since 2006 at approximately 2100 patients per year. The majority of foreign nationals seeking treatment in Belgium were French women for sperm donation. The next highest group was patients entering the country to obtain ICSI with ejaculated sperm. CONCLUSIONS: There are clear indications that numerous movements are motivated by the wish to evade legal restrictions in one's home country, either because the technology is prohibited or because the patients have characteristics, which exclude them from treatment in their own countries.
