Characterization of Neisseria gonorrhoeae isolates detected in Switzerland (1998–2012): emergence of multidrug-resistant clones less susceptible to cephalosporins

Background: The spread of Neisseria gonorrhoeae (Ng) isolates resistant to the clinically implemented antibiotics is challenging the efficacy of treatments. Unfortunately, phenotypic and molecular data regarding Ng detected in Switzerland are scarce. Methods: We compared the characteristics of Ng detected during 1998–2001 (n = 26) to those detected during 2009–2012 (n = 34). MICs were obtained with the Etest and interpreted as non-susceptible (non-S) according to EUCAST criteria. Sequence type (ST) was achieved implementing the NG-MAST. BlaTEM, ponA, penA, mtrR, penB, tet (M), gyrA, parC, mefA, ermA/B/C/F, rplD, rplV, and 23S rRNA genes were analyzed. Results: The following susceptibility results were obtained (period: % of non-S, MIC90 in mg/L): penicillin (1998–2001: 42.3%, 3; 2009–2012: 85.3%, 16), cefixime (1998–2001: 0%, ≤0.016; 2009–2012: 8.8%, 0.125), ceftriaxone (1998–2001: 0%, 0.004; 2009–2012: 0%, 0.047), ciprofloxacin (1998–2001: 7.7%, 0.006; 2009–2012: 73.5%, ≥32), azithromycin (1998–2001: 11.5%, 0.25; 2009–2012: 23.6%, 0.38), tetracycline (1998–2001: 65.4%, 12; 2009–2012: 88.2%, 24), spectinomycin (1998–2001: 0%, 12; 2009–2012: 0%, 8). The prevalence of multidrug-resistant (MDR) isolates increased from 7.7% in 1998–2001 to 70.6% in 2009–2012. International STs and genogroups (G) emerged during 2009–2012 (G1407, 29.4%; G2992, 11.7%; G225, 8.8%). These isolates possessed distinctive mechanisms of resistance (e.g., G1407: PBP1 with L421, PBP2 pattern XXXIV, GyrA with S91F and D95G, ParC with S87R, PorB with G120K and A121N, mtrR promoter with A deletion). Conclusions: The prevalence of penicillin- ciprofloxacin- and tetracycline-resistant Ng has reached dramatic levels, whereas cefixime and ceftriaxone show MICs that tend to increase during time. International MDR clones less susceptible to cephalosporins are rapidly emerging indicating that the era of untreatable gonococcal infections is close.

Gender and language in online job advertisements - a cross-cultural study

The aim of this project is to investigate the use of gender-fair language from a cross-linguistic perspective. Specifically, we are interested in whether the use of gender-fair language correlates with socio-economic rankings of gender equality and with structural features of a language. We decided to analyze online job advertisements, as they reflect common language use and can easily be compared across languages. Moreover, formulations in job advertisements have been shown to impact personnel selection via the way target groups are addressed and referred to. In the present study we examined to what extent job advertisements are formulated in a gender-fair way and how this correlates with factors such as language, culture as well as status and gender-typicality of the job advertised. The data consisted of job advertisements published online in four European countries which occupy different positions in socio-economic rankings of gender equality (World Economic Forum, 2011): Switzerland (10), Austria (rank 34), Poland (42), and Czech Republic (75). We randomly selected 100 job advertisements from four lines of business characterized by different proportions of female employees – steels/metals, science, restaurants/food services, and health care. The advertisements were analyzed with regard to the linguistic form of the job title and the remaining text; we also noted indicators of job status, reference to gender-typical traits, pictures of women/men and other information which might be relevant to the use of gender-fair language (e.g., equal opportunity policies). A first analysis of the data indicates that the phrasing of job titles is closely related to the gender-typicality of a profession. While mainly gender-fair forms are used in healthcare, masculine forms are used more often in the domain of steels and metals. Feminine forms only, however, are almost never used. Cultural differences as well as correlations with associated variables will be discussed.

Sprache und Geschlecht in online Stellenausschreibungen im interkulturellen Vergleich

Wie bisherige experimentelle Forschung gezeigt hat, beeinflusst die geschlechtergerechte Formulierung von Stellenausschreibungen die angesprochene Zielgruppe und damit die Personalauswahl. Wie verbreitet ist nun geschlechtergerechte Sprache in Stellenausschreibungen und mit welchen Faktoren hängt ihre Verwendung zusammen (z.B. Sprache, Kultur, Status und Geschlechtstypikalität des Berufes)? Wir untersuchten die Verwendung geschlechtergerechter Sprache in online publizierten Stellenausschreibungen in vier europäischen Ländern mit unterschiedlicher Geschlechtergleichstellung (World Economic Forum, 2011), nämlich die Schweiz, (10), Österreich (Rang 34), Polen (42) und Tschechien (75). Aus vier Branchen mit unterschiedlichen Anteilen weiblicher Angestellter – Stahl- und Metallbau, Forschung, Gastronomie und Gesundheitswesen – wurden jeweils 100 Stellenausschreibungen analysiert. Erste Analysen zeigen, dass die Formulierung der Stellenausschreibungen eng mit der Geschlechtstypikalität des Berufes zusammenhängt. So werden im Gesundheitswesen vorwiegend Formulierungen verwendet, die beide Geschlechter ansprechen. Dagegen sind die Stellenausschreibungen im Stahl- und Metallbau vermehrt rein maskulin formuliert. Feminine Formen werden kaum verwendet. Kultur- und sprachspezifische Unterschiede sowie Zusammenhänge mit sozioökonomischem Status werden diskutiert.

How women and men are addressed in job advertisements

Research has shown that gender references in job advertisements play an important role for gender (in)equality in personnel selection. In advertisements gender is referred to in different ways, for instance, by using grammatically masculine and feminine human nouns (e.g., German Mechaniker/Mechanikerin 'mechanic, masc./fem.'), by mentioning typically feminine or typically masculine traits (e.g., kind and friendly versus determined and independent) as well as by showing pictures of women and men. The present study addresses the questions which forms of gender references occur in job advertisements, how these forms are distributed across different lines of business and across different countries. We collected job advertisements published online in four countries with different rankings of gender equality (i.e., Switzerland, Austria, Poland, and Czech Republic; World Economic Forum, 2011). We randomly selected 100 advertisements per country from four lines of business that are characterized by different proportions of female and male employees: (1) steels/metals, (2) science, (3) restaurants/food services, and (4) health care. The advertisements were analyzed with regard to the linguistic form of the job title and of the remaining text as well as reference to gender-typical traits. We also examined indicators of job status and other information (e.g., equal opportunity policies) which might be related to the use of gender references in job advertisements. The results show that, in general, gender-fair language occurs much more often in job ads from Switzerland and Austria than in those from Poland and the Czech Republic, where job titles are mostly masculine. While exclusive use of feminine forms are almost never used in Switzerland and Austria, they are more frequently used in Poland and Czech Republic. In general, gender-fair forms are more common when there are many women in a line of business, whereas more masculine forms are used where the proportion of women is low. In Switzerland and Austria, masculine forms are mostly combined with the supplement m/f to indicate that both women and men are addressed. The present data provide a sound basis for future studies on gender references in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality.

Increasing the dynamic range for the analysis of boron in PGAA

Prompt gamma activation analysis (PGAA) is especially sensitive for elements with high neutron-capture cross sections, like boron, which can be detected down to a level of ng/g. However, if it is a major component, the high count rate from its signal will distort the spectra, making the evaluation difficult. A lead attenuator was introduced in front of the HPGe-detector to reduce low-energy gamma radiation and specifically the boron gamma rays reaching the detector, whose thickness was found to be optimal at 10 mm. Detection efficiencies with and without the lead attenuator were compared, and it was shown that the dynamic range of the PGAA technique was significantly increased. The method was verified with the analyses of stoichiometric compounds: TiB2, NiB, PVC, Alborex, and Alborite.

European summer temperature response to annually dated volcanic eruptions over the past nine centuries

The drop in temperature following large volcanic eruptions has been identified as an important component of natural climate variability. However, due to the limited number of large eruptions that occurred during the period of instrumental observations, the precise amplitude of post-volcanic cooling is not well constrained. Here we present new evidence on summer temperature cooling over Europe in years following volcanic eruptions. We compile and analyze an updated network of tree-ring maximum latewood density chronologies, spanning the past nine centuries, and compare cooling signatures in this network with exceptionally long instrumental station records and state-of-the-art general circulation models. Results indicate post-volcanic June–August cooling is strongest in Northern Europe 2 years after an eruption (−0.52 ± 0.05 °C), whereas in Central Europe the temperature response is smaller and occurs 1 year after an eruption (−0.18 ± 0.07 °C). We validate these estimates by comparison with the shorter instrumental network and evaluate the statistical significance of post-volcanic summer temperature cooling in the context of natural climate variability over the past nine centuries. Finding no significant post-volcanic temperature cooling lasting longer than 2 years, our results question the ability of large eruptions to initiate long-term temperature changes through feedback mechanisms in the climate system. We discuss the implications of these findings with respect to the response seen in general circulation models and emphasize the importance of considering well-documented, annually dated eruptions when assessing the significance of volcanic forcing on continental-scale temperature variations.

The epidemiology of chronic fatigue in San Francisco

Chronic fatigue syndrome (CFS) is a recently defined condition characterized by severe disabling fatigue that persists for a minimum of six months, and a host of somatic and neurocognitive symptoms. Although conditions similar to CFS have been described in the medical literature for over 100 years, little is known about the epidemiology of CFS or of chronic fatigue generally. The San Francisco Fatigue Study was undertaken to describe the prevalence and characteristics of self-reported chronic fatigue and associated conditions in a diverse urban community. The study utilized a cross-sectional telephone survey of a random sample of households in San Francisco, followed by case/control interviews of fatigued and nonfatigued subjects. Respondents were classified as chronically fatigued (CF) if they reported severe fatigue lasting six months or longer, then further classified as having CFS-like illness if, based on self-reported information, their condition appeared to meet CFS case definition criteria. Subjects who reported idiopathic chronic fatigue that did not meet CFS criteria were classified as having ICF-like illness.^ 8004 households were screened, yielding fatigue and demographic information on 16970 residents. CF was reported by 635 persons, 3.7% of the study population. CFS-like illness was identified in 34 subjects (0.2%), and ICF-like illness in 259 subjects (1.6%). Logistic regression analysis indicated that prevalence odds ratios for CFS-like illness were significantly elevated for females compared to males (OR = 2.9), and in Blacks (OR = 2.9) and Native Americans (OR = 13.2) relative to Whites, but significantly lower in Asians (OR = 0.12). Above-average household income was protective for all categories of CF. CFS-like subjects reported more symptoms and were more severely disabled than ICF-like subjects, but the pattern of symptoms experienced by both groups was similar. In conclusion, unexplained chronic fatigue, including CFS-like illness, occurs in all sociodemographic groups, but may be most prevalent among persons with lower incomes and in some racial minorities. Future studies that include clinical evaluation of incident cases of CFS and ICF are required to further clarify the epidemiology of unexplained chronic fatigue in the population. ^

In vitro Activity of Fosfomycin Alone and in Combination with Ceftriaxone or Azithromycin Against Clinical Neisseria gonorrhoeae Isolates.

New therapeutic strategies are needed to combat the emergence of infections due to multidrug-resistant Neisseria gonorrhoeae (Ng). In this study, fosfomycin (FOS) was tested against 89 Ng using the Etest method and showing MIC50/90s of only 8/16 μg/ml (range ≤ 1-32 μg/ml). FOS in combination with ceftriaxone (CRO) or azithromycin (AZT) was then evaluated using the checkerboard method for eight strains, including F89 (CRO-resistant) and AZT-HLR (high-level AZT-resistant). All combinations including FOS gave indifferent effects (fractional inhibitory concentration [FIC] index values between 1.2-2.3 for FOS plus CRO and between 1.8-3.2 for FOS plus AZT). Time-kill experiments for FOS, CRO, AZT and their combinations (at concentrations of 0.5×, 1×, 2× and 4× MIC) were performed against ATCC 49226, one Ng of NG-MAST ST1407, F89 and AZT-HLR. For all strains, at 24 hours results indicated that: i) FOS was bactericidal at 2× MIC concentrations but after >24 hours there was re-growth of bacteria; ii) CRO was bactericidal at 0.5× MIC; iii) AZT was bactericidal at 4× MIC; iv) CRO plus AZT was less bactericidal than CRO alone; v) FOS plus AZT was bactericidal at 2× MIC; vi) CRO plus AZT and FOS plus CRO were both bactericidal at 0.5× MIC, but the latter had more rapid effects. FOS is appealing for the management of Ng infections because of its single and oral formulation. However, our results suggest its use in combination with CRO. This strategy could, after appropriate clinical trials, be implemented for the treatment of infections due to isolates possessing resistance to CRO and/or AZT.

Gender-fair language use in online job advertisements - relations to job status and gender equality

Purpose Gender fair language use in job advertisements has been shown to impact the outcome of personnel selections. It is thus important to assess, to what extent gender fair language is used in job advertisements and with which factors it is associated, e.g., language, culture, status, and gender typicality of profession. Design/Methodology In the present research we investigated gender fair language use in job advertisements published online in four European countries with different socio-economic rankings of gender equality (World Economic Forum, 2011), namely Austria (rank 34), Czech Republic (75), Poland (42), and Switzerland (10). From four lines of business with different percentages of female employees – steels/metals, science, restaurants/food services, and health care –we randomly selected 100 job advertisements, summing up to 1600 job advertisements in total. Results A first analysis of the Swiss data indicates that the phrasing of job advertisements is closely related to a profession’s gender typicality (e.g., merely masculine forms are used in steels and metals, gender-fair forms in healthcare). Feminine forms however are almost never used. Cross-cultural comparisons will be presented. Limitations We analyzed job advertisements of four specific lines of business in four European countries. To what extend results can be generalized remains an open question. Research/Practical Implications The present data provide a sound basis for future studies on gender fair language use in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality. Originality/Value This is the first time that gender fair language use in job advertisements is investigated (a) across different countries and languages and (b) considering status and gender typicality of professions.
