Low seroprevalence of hepatitis E virus among blood donors in Switzerland

Introduction: Hepatitis E virus (HEV) emerged as an autochthonous food-borne disease in developed countries, transmitted mainly through pork meat. Cases of transmission through blood transfusion have been reported. Recent studies revealed sero-prevalence rates of 13.5%, 16.6% and 20.6% among blood donors in England, France and Denmark, respectively. The aim of this study was to determine the sero-prevalence of HEV among Swiss blood donors. Method: We screened 550 consecutive blood donations from the Service Régional Vaudois de Transfusion Sanguine of Epalinges, for the presence of anti-HEV IgG (MP Diagnostics HEV ELISA). The sample size was based on the Lorentz formula considering an expected prevalence of 3% with a precision of 1.5%. For each donor, we studied the following variables: age, sex and alanine aminotransferase (ALT) value. Results: All blood donors were Caucasian, and included 332 men (60.4%) and 218 women (39.6%). The median age was 55 years (IQR 46-63 years). Overall, anti-HEV IgG were found in 27 of 550 samples (4.9%). The sero-prevalence was 5.4% (18/314) in men and 4.1% (9/209) in women. The presence of anti-HEV IgG was not correlated to age, gender or ALT values. Conclusion: Compared to other European countries, the HEV sero-prevalence among blood donors in Switzerland is surprisingly low. Possible explanations include the strict regulation of animals and meat import. However, to confirm this hypothesis, further studies assessing the prevalence of HEV in Swiss swine will be necessary.

La formation des psychologues conseillères et conseillers en orientation en Suisse

Il existe quatre filières de formation pour les psychologues conseillères et conseillers en orientation scolaire et professionnelle en Suisse. Une d'entre elles est de niveau universitaire et les trois autres sont de niveau post-grade (deuxième ou troisième cycle). Une des filières post-grade est proposée par une Université de sciences appliquées. Tout en étant spécifiques aux régions linguistiques, ces formations rendent compte d'un profil de compétences défini au niveau national. Le modèle théorique qui fonde généralement ces formations est éclectique. L'apprentissage social et la problématique de l'ajustement au contexte sont également des aspects qui constituent cette approche intégrative.

The impact of clinical maternal chorioamnionitis on neurological and pshicological sequelae in very-low-birthweight infants: a case-control study

Aims: To assess the relationship between clinically maternal chorioamnionitis and outcome in preterm very-low-birth weight (VLBW) infants. Methods: An observational case-control study was conducted in the neonatology departments of 12 acute care teaching hospitals in Spain. Between January 2004 and December 2006, all consecutive VLBW (F1500 g) infants who were born to a mother with clinical chorioamnionitis were enrolled. The controls included infants who were born to mothers without chorioamnionitis, matched by gestational age, and immediately born after each index case. At a corrected age of 24 months, a neurological examination and a psychological assessment of the surviving children were performed.Results: Sixty-six of the newborn infants died; therefore, 262 infants from the original sample were available for the study. Follow-up data were obtained at a corrected age of 24 months from a total of 209 children (106 cases and 103 controls, 80% of the original sample size). Seventy children (33.5%) were diagnosed with some type of sequelae. The following conditions were all more prevalent in infants born to mothers with chorioamnionitis in comparison to controls: low development quotient (98.3'12.15 vs. 95.9'15.64; Ps0.497), cerebral palsy (4.9% vs. 10.4%; Ps0.138), seizures (1.0% vs. 3.8%; Ps0.369), and other neurological or sensorial sequelae (32.0% vs. 34.9%; Ps0.611). Conclusions: After controlling for gestational age, the study population demonstrated that the neurological outcomes in infants at a corrected age of 24 months was not worsened by chorioamnionitis.

Awakening dormant haematopoietic stem cells.

Haematopoietic stem cells (HSCs) in mouse bone marrow are located in specialized niches as single cells. During homeostasis, signals from this environment keep some HSCs dormant, which preserves long-term self-renewal potential, while other HSCs actively self renew to maintain haematopoiesis. In response to haematopoietic stress, dormant HSCs become activated and rapidly replenish the haematopoietic system. Interestingly, three factors - granulocyte colony-stimulating factor, interferon-alpha and arsenic trioxide - have been shown to efficiently activate dormant stem cells and thereby could break their resistance to anti-proliferative chemotherapeutics. Thus, we propose that two-step strategies could target resistant leukaemic stem cells by priming tumours with activators of dormancy followed by chemotherapy or targeted therapies.

Overlapping Pathways to Transplant Glomerulopathy: Chronic Humoral Rejection, Hepatitis C Infection and Thrombotic Microangiopathy

Background:Transplant glomerulopathy (TG) has received much attention in recent years as a manifestation of chronic humoral rejection (CHR). However, many cases lack C4d deposition and/or circulating donor-specifi c antibodies, and the contribution of other potential causes has not been fully addressed.Methods: Of 209 consecutive renal allograft indication biopsies performed for chronic allograft dysfunction, 25 that met pathologic criteria of TG (>10% duplication of the GBM without immune complex deposition) were examined for various etiologies, including hepatitis C infection (HCV), thrombotic microangiopathy (TMA), and CHR. 29 cases of biopsy-proven isolated chronic calcineurin inhibitor toxicity from the same time period were used as controls for comparing the prevalence of HCV.Results: Three partially overlapping categories accounted for 84% of the cases: C4d+TG (48%), HCV+TG (36%) and TMA+TG (32%). The majority of TMA+ cases were HCV+ (63%) and the majority of HCV+ cases had TMA (56%). Donor specifi c antibodies were associated with C4d+TG (7/8 vs. 1/4 C4d-TG; P<0.02), but not with HCV+TG. The prevalence of HCV was higher in the TG group than in 29 control patients without TG (36% vs. 7%, P<0.01). HCV+TG patients developed allograft failure earlier than HCV-TG patients (67.2 ± 60.2 mo versus 153.4 ± 126.2 mo, P=0.02). On a multivariate analysis, out of HCV, TG and C4d, only HCV was found to be a signifi cant risk factor for a more rapid allograft loss.Conclusion: We conclude that TG is not a specifi c diagnosis, but a pattern of pathologic injury with 3 major overlapping pathways involving CHR, HCV infection and TMA. It is important to distinguish these mechanisms, as they may have differentprognostic and therapeutic implications.

Is screening for fetal anomalies reliable in HIV-infected pregnant women? A multicentre study.

OBJECTIVE: To assess the impact of HIV infection on the reliability of the first-trimester screening for Down syndrome, using free beta-human chorionic gonadotrophin, pregnancy-associated plasma protein-A and fetal nuchal translucency, and of the second-trimester screening for neural tube defects, using alpha-fetoprotein. PATIENTS AND METHODS: Multicentre study comparing the multiples of the median of markers for Down syndrome and neural tube defect screening among 214 HIV-infected pregnant women and 856 HIV-negative controls undergoing a first-trimester Down syndrome screening test, and 209 HIV-positive women and 836 HIV-negative controls with a risk evaluation for neural tube defect. The influence of treatment, chronic hepatitis and HIV disease characteristics were also evaluated. RESULTS: Multiples of the median medians for pregnancy-associated plasma protein-A and beta-human chorionic gonadotrophin were lower in HIV-positive women than controls (0.88 vs. 1.05 and 0.84 vs. 1.09, respectively; P < 0.005), but these differences had no impact on risk estimation; no differences were observed for the other markers. No association was found between HIV disease characteristics, antiretroviral treatment use at the time of screening or chronic hepatitis and marker levels. CONCLUSION: Screening for Down syndrome during the first trimester and for neural tube defect during the second trimester is accurate for HIV-infected women and should be offered, similar to HIV-negative women.

Ein unbekanntes Fragment der "Alexandreis" Walters von Châtillon

Das im letzten Viertel des 12. Jahrhunderts entstandene Alexander-Epos Walters von Châtillon, schon im 13. Jahrhundert in den ,,status of a classic" (Colker) und überdies zum Schultext avanciert, gehört zu den am reichhaltigsten überlieferten Erzähltexten der lateinischen Literatur des Mittelalters. Der Beitrag kann ausser den in der Ausgabe Colkers (1987) nachgewiesenen 209 Textzeugen 15 weitere Handschriften und Fragmente belegen und zudem einen Neufund vorstellen: Im Archiv der Bürgergemeinde Frauenfeld, Schweiz, erhielt sich als einzelnes Doppelblatt ein glossiertes Fragment des Textes aus dem späten 13. oder frühen 14. Jahrhundert. Sein Layout verrät, dass es für die begleitende Kommentierung von vornherein angelegt war und vermutlich einem Schulbuch entstammt. Die erhaltenen Scholien scheinen dem ,,Standardkommentar" (Killermann) zur ,Alexandreis' nahezustehen, könnten aber auch Bezüge zum Kommentar des Geoffrey de Vitry aufweisen, der in einer mit seinem Namen auktorial verbundenen, aus Rheinau stammenden Handschrift erhalten ist. In vergleichsweise dichter räumlicher und zeitlicher Nähe zu diesem Textzeugen entstand die Handschrift, aus der das neue Frauenfelder Fragment stammt: Die Untersuchung der Akte, als deren Schutzumschlag das Doppelblatt aus der ,Alexandreis' diente, zeigt, dass sie sich seit dem frühen 15. Jahrhundert im jetzigen Kontext, den Beständen des heutigen Archivs der Frauenfelder Bürgergemeinde, befunden hat, das auf eine seit dem 13. Jahrhundert geführte Sammlung zurückgeht. Da zudem in Frauenfeld eine Lateinschule seit dem 14. Jahrhundert nachweisbar und schon im 13. Jahrhundert zu vermuten ist, liegt es nahe, dass der Fundort des neuen Textzeugen auch der seiner Entstehung oder doch zumindest seiner Benutzung im Unterricht war. Das Fragment bietet einen trotz schlechter Abschrift (mit häufigen Korrekturen durch den Glossator) unverkennbar guten Text, in kritischer Hinsicht dabei nur geringen Gewinn. Seine textgeschichtliche Verortung kann angesichts der nach wie vor weitgehend unaufgearbeiteten Überlieferung der ,Alexandreis' nur in groben Zügen vorgenommen werden. - Mit einem durch einen kritischen Apparat erschlossenen diplomatischen Abdruck und zwei Abbildungen des neuen Fragments.

Iowa Influenza Surveillance Network: Weekly Activity Report Week 9, March 5, 2016

The Iowa Influenza Surveillance Network (IISN) was established in 2004, though surveillance has been conducted at the Iowa Department of Public Health. Schools and long-term care facilities report data weekly into a Web-based reporting system. Schools report the number of students absent due to illness and the total enrolled. Long-term care facilities report cases of influenza and vaccination status of each case. Both passively report outbreaks of illness, including influenza, to IDPH.

The fixation of metacentric chromosomes during the chromosomal evolution in the common shrew (Sorex araneus, Insectivora)

Rb fusions between acrocentric chromosomes leading to metacentrics tend to become fixed during the chromosomal evolution in the common shrew. Using microsatellite markers preliminary results show that populations are only slightly subdivided and genetic drift seems not to play an important role for the fixation of metacentrics. A significant segregation distortion in favour of metacentric chromosomes was found during male meiosis. This suggests that cytological factors such as facilitated fusion between acrocentric chromosomes or choice-effects at the level of gametes are more likely to play a role for the chromosomal evolution in the common shrew.

Medical and pharmacological direct costs of a 9-week smoking cessation programme.

Background: Medical and pharmacological direct costs of cigarette smoking cessation programmes are not covered by health insurance in several countries despite documented cost-effectiveness. Design: prospective cost identification study of a 9-week programme in Switzerland. Methods: A total of 481 smokers were followed-up for 9 weeks. Socio-demographic characteristics, number of outpatient visits, dosage and frequency of use of nicotine replacement therapy (NRT) as well as date of relapse were prospectively collected. Individual cost of care until relapse or programme end as well as cost per week of follow-up were computed. Comparisons were carried out between the groups with or without relapse at the end of the programme. Results: Of the 209 men and 272 women included, 347 patients (72%) finished the programme. Among them, 240 patients (70%) succeeded in quitting and 107 patients (30%) relapsed. As compared with the group relapsing by the end of the programme, the group succeeding in quitting was more often living in a couple (68% vs. 55%, p = 0.029). Their mean weekly costs of visits were higher (CHF 81.2 ± 6.1 vs. 78.4 ± 7.6, p = 0.001), while their mean weekly costs for NRT were similar (CHF 24.2 ± 12.6 vs. 25.4 ± 15.9, p = 0.711). Mean total costs per week were similar (CHF 105.4 ± 15.4 vs. 103.8 ± 19.4, p = 0.252). More intensive NRT at week 4 increased the probability not to relapse at the end of the programme. Conclusions: Over 9 weeks, medical and pharmacological costs of stopping smoking are low. Good medical and social support as well as adequate NRT seem to play a role in successful quitting.
