Changing molecular epidemiology of methicillin-resistant Staphylococcus aureus in an Algerian hospital.

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of both hospital- and community-acquired infections worldwide. However, data about the molecular epidemiology of MRSA in North Africa are still scarce. METHODOLOGY: All MRSA isolates recovered between January 2006 and July 2011 from one Algerian hospital were genetically and phenotypically characterized. RESULTS: The predominance of a European community-associated-MRSA (CA-MRSA) clone (ST80-SCCmec IV-PVL positive) was revealed by this analysis. CONCLUSION: Our data suggest that a CA-MRSA clone recently invaded the hospital setting in Algiers and replaced a typical hospital-associated pandemic clone such as the Brazilian clone (ST239-SCCmec IIImercury-PVL negative).

The T309G Murine Double Minute 2 Gene Polymorphism Is an Independent Prognostic Factor for Patients with Renal Cell Carcinoma.

The purpose of this study was to evaluate the association of the T309G MDM2 gene polymorphism with renal cell carcinoma (RCC) risk, pathology, and cancer-specific survival (CSS). T309G MDM2 was genotyped in 449 Caucasians, including 240 with RCC and 209 cancer-free controls. The T309G MDM2 genotype was TT in 174 (38.8%), GT in 214 (47.7%), and GG in 61 (13.6%) subjects, without any significant differences between cases and controls on both univariable (p=0.58) and multivariable logistic regression (each p>0.25). Furthermore, T309G MDM2 was not linked with T stage (p=0.75), N stage (p=0.37), M stage (p=0.94), grade (p=0.21), and subtype (p=0.55). There was, however, a statistically significant association of T309G MDM2 with CSS (p=0.022): patients with TT had significantly worse survival than GG/GT (p=0.009), while those with GT and GG had similar outcomes (p=0.92). The 5-year survival rate for patients with TT, GT, and GG was 69.5%, 84.5%, and 89.7%, respectively. On the multivariable analysis, T309G was identified as an independent prognostic factor. The T309G MDM2 polymorphism is an independent prognostic factor for patients with RCC, with the TT genotype being associated with worse prognosis. In this study, there were no significant associations with RCC risk and pathology.

Melt/peridotite interaction in the Southern Lanzo peridotite: Field, textural and geochemical evidence

This paper presents field, petrographic-structural and geochemical data on spinet and plagioclase peridotites from the southern domain of the Lanzo ophiolitic peridotite massif (Western Alps). Spinet lherzolites, harzburgites and dunites crop out at Mt. Arpone and Mt. Musine. Field evidence indicates that pristine porphyroclastic spinet lherzolites are transformed to coarse granular spinet harzburgites, which are in turn overprinted by plagioclase peridotites, while strongly depleted spinet harzburgite and dunite bands and bodies replace the plagioclase peridotites. On the northern flank of Mt. Arpone, deformed, porphyroclastic (lithospheric) lherzolites, with diffuse pyroxenite banding, represent the oldest spinel-facies rocks. They show microstructures of a composite subsolidus evolution, suggesting provenance from deeper (asthenospheric) mantle levels and accretion to the lithosphere. These protoliths are locally transformed to coarse granular (reactive) spinet harzburgites and dunites, which show textures reminiscent of melt/rock reaction and geochemical characteristics suggesting that they are products of peridotite interaction with reactively percolating melts. Geochemical data and modelling suggest that <1-5% fractional melting of spinel-facies DMM produced the injected melts. Plagioclase peridotites are hybrid rocks resulting from pre-existing spinet peridotites and variable enrichment of plagioclase and micro-gabbroic material by percolating melts. The impregnating melts attained silica-saturation, as testified by widespread orthopyroxene replacement of olivine, during open system migration in the lithosphere. At Mt. Musine, coarse granular spinet harzburgite and dunite bodies replace the plagioclase peridotites. Most of these replacive, refractory peridotites have interstitial magmatic clinopyroxene with trace element compositions in equilibrium with MORB, while some Cpx have REE-depleted patterns suggesting transient geochemical features of the migrating MORB-type melts, acquired by interaction with the ambient plagioclase peridotite. These replacive spinet harzburgite and dunite bodies are interpreted as channels exploited for focused and reactive migration of silica-undersaturated melts with aggregate MORB compositions. Such melts were unrelated to the silica-saturated melts that refertilized the pre-existing plagioclase peridotites. Finally, MORB melt migration occurred along open fractures, now recorded as gabbroic dikes. Our data document the complexity of rock-types and mantle processes in the South Lanzo peridotite massif and describe a composite tectonic and magmatic scenario that is not consistent with the ``asthenospheric scenario'' proposed by previous authors. We envisage a ``transitional scenario'' in which extending subcontinental lithospheric mantle was strongly modified (both depleted and refertilized) by early melts with MORB-affinity formed by decompression partial melting of the upwelling asthenosphere, during pre-oceanic rifting and lithospheric thinning in the Ligurian Tethys realm.

1118-007 Lake Hendricks Watershed Final Report

Lake Hendricks is a 54 acre man-made lake that is encompassed by a 1,209 acre watershed. Lake Hendricks is currently on the 303(d) Impaired Waters List for algae and pH impairments due to an abundance of algae growth caused by nutrients being delivered to the lake via 11 separate tile lines draining adjoining cropland areas. In 2009, a Watershed Management Plan was developed in partnership with IDALS and the IDNR 319 programs and $256,500 was awarded to address the nutrient and sediment loading of the lake. Over the past three years a total of $251,000 were spent to implement one grade stabilization structure, two sediment basins, two bioreactors, 700 feet of streambank stabilization, 30.7 acres oftimber stand improvement, and 39.4 acres of Conservation Reserve Program (CRP). A proposed wetland structure and three sediment basins are scheduled to be constructed in the fall of 2011. Current water monitoring data is showing an average of 54% Nitrate (N) loading reductions as a result of the installed BMPs. The District feels further reductions are possible by addressing nutrient management issues in the cropland areas, stabilizing additional streambanks, and improving the surrounding woodland areas. The goal is to reduce N loading by an additional 20% and sediment loading by 50 tlac/yr. The resulting collaborative effort may lead to the future de-listing of Lake Hendricks from the 303(d) Impaired Waters List.

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.
