Authors: Suárez-Esquivel Marcela , Alfaro-Alarcón Alejandro , Guzmán-Verri Caterina , Barquero-Calvo Elías
Published: November 2017

OBJECTIVE To evaluate the correlation between the density of native gastric Helicobacter spp and the presence of gastric lesions in dogs.

ANIMALS 80 dogs of various breeds, sexes, and ages.

PROCEDURES Gastroscopic and histologic examinations were performed for all dogs. Helicobacter spp were detected by combining evaluation of urease activity and results of bacteriologic culture, microscopic observation, and a 16S rRNA PCR assay. The density of Helicobacter-like organisms was evaluated with light microscopy by use of Warthin-Starry modified stain. Correlations were evaluated by use of the Spearman correlation analysis.

RESULTS Gastritis was found in 55 of 80 dogs and classified as mild (n = 31), moderate (16), or severe (8). Of these 55 dogs, only 8 had clinical signs. Histologic examination revealed some degree of lymphocytic-plasmacytic infiltrate, mild eosinophilia, and neutrophilic inflammation in the lamina propria. Seventy-six dogs had positive results for Helicobacter spp. Helicobacter pylori DNA was not detected. Low density and homogeneous distribution of Helicobacter spp were observed in all gastric zones.

CONCLUSIONS AND CLINICAL RELEVANCE A significant correlation between density of Helicobacter spp and gastroscopic or histologic lesions was not detected. These findings supported the contention that there is no correlation between general Helicobacter spp density or numbers and gastritis in dogs.

OBJECTIVE To evaluate the effects of meloxicam on movement, feeding, and drinking behaviors of transported and nontransported cattle.

ANIMALS 100 crossbred beef steers.

PROCEDURES During experiment 1 of a 2-experiment study, calves from a livestock auction received meloxicam (1 mg/kg, PO; n = 50) or a lactose placebo (1 capsule/calf; 50; control), then calves were transported approximately 1,000 km overnight to a feedlot, where they were instrumented with a real-time location-monitoring ear tag, placed in randomly assigned pens (n = 5 pens/treatment), and monitored for 21 days. During experiment 2, calves in pens were administered the treatment opposite that of experiment 1, returned to their pens without undergoing transportation, and monitored for another 21 days. For each experiment, mean daily distance traveled and percentage time spent near feed (PNF) and water (PNW) were calculated on a pen basis and compared between treatments.

RESULTS During experiment 1, mean daily distance traveled, PNF, and PNW did not differ significantly between meloxicam-treated and control calves; however, all 3 behaviors varied significantly by day. During experiment 2, although mean distance traveled was significantly associated with the interaction between day and treatment, it did not differ significantly between meloxicam-treated and control calves within any specific day. Mean PNF and PNW were significantly associated with day only, although no pattern in that effect was evident.

CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that a single dose of meloxicam prior to transportation did not significantly affect the behaviors of transported and nontransported calves.

Published: November 2017

Peningkatan suhu di kawasan perkotaan adalah salah satu dampak dari urbanisasi. Fenomena Urban Heat Island (UHI) merupakan salah satu akibat yang dihasilkan akibat peningkatan suhu tersebut. Diperlukan upaya untuk menilai perubahan suhu apakah dapat berbahaya bagi manusia atau tidak. Melalui pengukuran UHI, pengaruh pembangunan kota terhadap peningkatan suhu dapat diukur. Tujuan penelitian ini adalah untuk memberikan panduan ilmiah tentang perolehan intensitas dan distribusi UHI menggunakan teknik penginderaan jauh. Studi kasus yang dilakukan berada di Kota Yogyakarta, Daerah Istimewa Yogyakarta. Citra penginderaan jauh yang digunakan adalah citra Landsat 8 perekaman tanggal 24 Juni 2013, path/row 120/65. Metode ekstraksi suhu permukaan menggunakan inversi persamaan Planck dengan koreksi emisivitas dan atmosfer menggunakan radiative transfer equation. Hasil pengolahan didapatkan intensitas UHI sebesar ±2,5oC pada Kota Yogyakarta dan intensitas UHI sebesar ±3,23oC pada area yang diperluas dengan buffer 1 km dari batas Kota Yogyakarta. Hal ini menunjukkan bahwa pemilihan area penelitian untuk analisis UHI menjadi penting karena mempengaruhi nilai intensitas UHI dan distribusi UHI. Ditemukan kawasan Malioboro dan sekitarnya berpotensi kuat terjadi UHI, sehingga perlu upaya mitigasi UHI pada kawasan tersebut. Pengukuran UHI menggunakan penginderaan jauh dipengaruhi oleh hal-hal yang berkaitan dengan sistem penginderaan jauh, seperti validasi dan akurasi hasil estimasi, pengaruh atmosfer, dan perbedaan waktu intensitas puncak UHI. Metode perolehan UHI dalam penelitian ini dapat menjadi panduan ilmiah yang digunakan untuk dasar evaluasi pembangunan perkotaan untuk lebih baik.

Authors: Shaer Fayez El , Raslan Ismail R , Habeeb Waleed Al , Alshimiri Mostafa , Albaker Hanan , AlHabib Khalid
Published: November 2017

Background:

Coronary heart disease with acute coronary syndrome (ACS; type II myocardial infarction) may be an iatrogenic and a reversible cause with complete recovery after cessation of the accused agent.

Case Presentation:

We present the case of a 52-year-old male patient who had received adjuvant chemotherapy consisting of capecitabine, 3 mg orally once per day, after resection of moderately differentiated invasive adenocarcinoma in the transverse colon. Three days (3 doses) after the initiation of chemotherapy, the patient reported typical anginal chest pain and an electrocardiogram (ECG) indicated ST-segment elevation. A repeated ECG in the catheterization laboratory showed normal results. Echocardiography showed that left ventricular systolic function was moderately to severely reduced. Coronary angiography revealed normal coronary arteries.

Conclusion:

Capecitabine should be used with caution, as patients receiving this medication might present with symptoms suggestive of ACS that might not always originate from epicardial coronary artery disease. There is always a possibility of vasospasm when a patient is receiving Capecitabine.

Authors: Guichot  Reina Emilio
Published: November 2017

Las nuevas Autoridad independientes de transparencia han adoptado posiciones enfrentadas sobre cuál sea la normativa aplicable a las solicitudes de información realizadas por los representantes políticos y acerca de su propia competencia para conocer las reclamaciones que éstos puedan plantear. El derecho de acceso a la información de los representantes políticos no puede tener un alcance menor en su contenido sustantivo, procedimental y de garantías que el que la nueva normativa sobre transparencia y acceso a la información reconoce a cualquier persona. La jurisprudencia del Tribunal Supremo lo ha afirmado de forma rotunda. Contribuiría a la seguridad jurídica que este criterio se asentara en la doctrina de las Autoridades independientes de transparencia y que una reforma legislativa lo contemplara expresamente.

Authors: Paul A. Deevan , Samatha P. , Manasa S. , Munemma R. , Supriya D.
Published: November 2017

Oral mucosal drug delivery system is widely applicable as novel site for administration of drug and controlled release action by preventing first pass metabolism and enzymatic degradation due to GI microbial flora. The oral cavity represents a challenging area to develop an effective drug delivery modelling. This arises due to the various inherent functions of the oral cavity (eating, swallowing, speaking, chewing), as well as the presence of the fluid that is involved in all these activities, saliva. This fluid is continually secreted into and then removed from the mouth. Oral Mucosa drug delivery system provides local and systemic action. The delivery of drugs through the buccal mucosa has attracted much research interest over the past two decades and numerous approaches, both conventional and complex, have been developed in an attempt to deliver a variety of pharmaceutical compounds via the buccal route. To outline the progress in the in vitro and in vivo modeling of Mucosal drug delivery and provide a critical review of currently used methods. The purpose of this review is to represent the modeling of oral cavity with Mucoadhesive drug delivery systems and clarify the potential alternative to conventional therapy.

Published: November 2017

The present investigation was aimed with the objective of developing fast dissolving oral films of Aripiprazole to attain quick onset of action for the better management of Schizophrenia. Fourteen formulations (F1-F14) of Aripiprazole mouth dissolving films by solvent-casting method using HPMC E5, HPMC E15, Maltodextrin, PG and PVA. Formulations were evaluated for their physical characteristics, thickness, folding endurance, tensile strength, disintegration time, drug content uniformity and drug release characteristics and found to be within the limits. Among the prepared formulations F13 showed minimum disintegration time 10 sec, maximum drug was released i.e. 99.49 ± 0.36% of drug within 8 min when compared to the other formulations and finalized as optimized formulation. FTIR data revealed that no interactions take place between the drug and polymers used in the optimized formulation. The in vitro dissolution profiles of marketed product and optimized formulation was compared and found to be the drug released was 20.73 ± 0.25 after 8 min. Therefore, it can be a good alternative to conventional Aripiprazole for immediate action. In vitro evaluation of the Aripiprazole fast dissolving oral films confirmed their potential as an innovative dosage form to improve delivery and quick onset of action of Aripiprazole. The mouth dissolving film is potentially useful for the treatment of Schizophrenia where the quick onset of action is desired.

Published: November 2017

Recorded are 59 oribatida species belong to 34 genus, 20 families. In the comparision with Vu Quang Manh (2013), there are 38 species were first recorded in the reseach region, 15 species are new for the Vietnamese fauna (Vu Quang Manh, 2013). The species number in different soil types oscillated from 16 species to 26 species .

A remark can be made after analysing 4 oribatida communities is that all the three oribatida communities in the group of alluvial soil are more diverse and more stable than yellow-red hummus on the mountains. There may be a specific community formed in coastal saline-acid soil. This community is a complex of species adapt to saline-acid soil, so it is not diverse in the number of species but is very stable.

The result shown that soil type is in the close relationship to the oribatida community structure. Therefore oribatida can be used as a bioindicator of soil quality and proposed as a means for sustainable management of soil ecosysterm.

Published: November 2017

The limited radio frequency spectrum that can be used for transmission leads to bandwidth and power efficiency being a key requirement in the development of wireless access technology from 3G to 5G today. Data communication technology also requires this as mentioned on high speed network standards such as DSL, WLAN and WMAN with its products ADSL, WiFi and Wimax. In the last few decades we have seen the evolution of the Orthogonal Frequency Division Multiplexing (OFDM) modulation technique used in the technologies mentioned earlier to this day. This technique is regarded as a standard technology for broadband wireless access technology. In hardware implementation, the most preferred by many researchers is the Field Programmable Gate Array chip, as it can be reconfigured. The OFDM technique can be easily implemented because it uses Fast Fourier Transform (FFT) algorithms that are coding and programming capable of reducing the computational time of Discrete Fourier Transform. This paper discusses the implementation of the memory-based 1024-point IFFT / FFT for BWA communications. The design is focused on synthesizing and implementing the system block FFT 1024-point radix-4 using Decimation in Frequency (DIF) method. Implementation for IFFT / FFT 1024-point resource usage slice number 1%, the number of slice flip-flop 1%, the number 4 LUT (Look Up Table) 1%, and the number of IOB 27%. of the FPGA are used.

Scrambling and De-Scrambling Implementation Using Linear Feedback Shift Register Method on FPGA
Authors: Lurina Manda , Hadiyoso Sugondo , Pudji Astuti Rina
Published: November 2017

communication system, a long sequence of bits ‘0’ or ‘1’ will inherits the loss of bit synchronization, and hence it can cause the false detection on the receiver. To avoid this, long sequence of bits will be randomized first so that long sequence of bits ‘0’ or ‘1’ can be removed. This randomization process is called scrambling and the circuit that works for the process is a scrambler. In the receiver there is a descrambler that serves to return the bits to their original information. This paper presents a design of scrambler and descrambler using a combination of Linear Feedback Shift Register (LFSR) with 15 registers, XOR logic gates, and Pseudo Random Binary Sequence (PRBS) generator structure with polynomial 1 + x14 + x15. One of the two main parts of LFSR is the shift register while the other is the feedback. In LFSR, the bits contained within the selected position in the shift register will be combined in a function and the result will be put back into this register's input bit. Feedback also makes the system more stable and no error occurrence. Then special tap is taken from a certain point in XOR and returned as a feedback register. The system is implemented on FPGA board Altera De0-Nano EP4CE22F17C6 Cyclone IV E. Resource memory required <1% of available memory. Bit rate that can be achieved with clock speed 50MHz is 335570.47 bps.

Like other cultures, batik has undergone many developments and changes. Batik Parang in particular has experienced it many times in different periods with a very long time span. From this period, we can see that batik parang have also experienced some ups and downs conditions, which not only caused by outside influences, but also can be caused by various influences from within his own culture. In a due process of change will produce a wide range of output that inevitably will influence directly a form of culture. These conditions also experienced by batik, especially batik parang in the process of developing and adapting to changes. As in batik parang, which evolved from court art, must be degraded into folk art. Batik in order to survive as a cultural form, should be able to adapt changes and sacrificed by decreasing its symbolic meanings to continued its existence in the future.

Published: November 2017

Objetivou-se com o presente estudo avaliar respostas morfológicas e fisiológicas durante o crescimento vegetativo inicial de plantas cv. Catuaí Vermelho IAC 144 submetidas à aplicação via foliar de quatro concentrações (250, 500, 750 e 1000 mg L-1) de pacloblutrazol (PBZ) e uma testemunha. O experimento foi conduzido em casa de vegetação com uma planta por vaso, em blocos ao acaso. Avaliaram-se o diâmetro do caule, número de folhas, massas fresca e seca da planta, índice SPAD, área foliar, potencial hídrico foliar e trocas gasosas. Os dados foram submetidos à análise de variância geral e da regressão. As características morfológicas foram afetadas pelo PBZ, ocorrendo redução do crescimento da parte aérea e elevação do peso de massa seca de raízes quando comparada à testemunha. Para os parâmetros fisiológicos o PBZ resultou em impactos positivos como a elevação do índice SPAD, do potencial hídrico foliar antemanhã, da fotossíntese líquida e da eficiência de carboxilação. A taxa de fotossíntese líquida potencial foi afetada pela eficiência da carboxilação, e a transpiração foi associada à maior disponibilidade hídrica da planta. O PBZ alterou a relação entre parte aérea e raiz, favorecendo o crescimento das raízes e otimizando as relações de trocas gasosas, devido à elevação do status hídrico da planta. Os efeitos do PBZ foram mais evidentes na morfologia do crescimento inicial dos cafeeiros quando comparados às alterações fisiológicas.

No Brasil a cafeicultura se expande para regiões mais quentes com a cultivar clonal Conilon ‘BRS Ouro Preto’ da espécie C. canephora. A resposta da ‘BRS Ouro Preto’ à inoculação com fungos micorrízicos arbusculares (FMAs) ainda não foi testada. O presente estudo visou selecionar espécies de FMAs promotoras do crescimento e nutrição fosfatada da referida cultivar. Avaliaram-se três clones (M057, M194 e M199) em três Argissolos Vermelho-Amarelos, coletados em áreas sob: cana-de-açúcar (Solo 1), Cerrado (Solo 2) e Mata Atlântica (Solo 3). Os tratamentos de inoculação foram: Acaulospora colombiana+Glomus sp., Acaulospora scrobiculata, Claroideoglomuse tunicatum+Glomus sp., Dentiscutata heterogama, Gigaspora margarita e Rhizophagus clarus, além de duas testemunhas não inoculadas, uma delas com adubação completa. O primeiro e o terceiro solos proporcionaram maior desenvolvimento vegetativo às plantas. O teor de clorofila e fósforo nas folhas foi maior nas plantas do solo 3. A melhor resposta à inoculação, expressa através do crescimento e nutrição das plantas, foi verificada no solo 1, sendo os melhores tratamentos C. etunicatum+ Glomus sp. e G. margarita. A espécie Glomus sp., presente nos tratamentos A. colombiana + Glomus sp. e C. etunicatum+Glomus sp., apresentou alta esporulação e promoveu o crescimento e nutrição da ‘BRS Ouro Preto’. Os clones M057 e M194 apresentaram maior crescimento, resposta à inoculação e esporulação de FMAs, comparados ao clone M199. Assim, os clones M057 e M194 podem ser considerados micotróficos e promotores da esporulação, enquanto o clone M199 caracteriza-se por baixa micotrofia.

O paclobutrazol pode atenuar os efeitos negativos do estresse hídrico em diversas espécies vegetais, todavia, para cafeeiros é necessário ampliar a base de conhecimentos sobre este tema. Neste estudo, objetivou-se avaliar a morfofisiologia de plantas jovens de Coffea arabica var. ‘Catuaí Vermelho IAC 144’ em resposta a diferentes regimes hídricos e concentrações de paclobutrazol aplicado via solo. O experimento foi conduzido em casa de vegetação em Vitória da Conquista, BA. O delineamento experimental foi em blocos casualizados, com esquema fatorial representado por cinco concentrações de paclobutrazol (0, 50, 100, 150 e 200 mg L-1) aplicado via solo e dois regimes hídricos (com e sem restrição hídrica), em cinco repetições. Aos 120 dias após a aplicação do regulador vegetal avaliou-se o status hídrico, o índice SPAD e as características morfológicas das plantas. A aplicação de paclobutrazol reduziu o índice SPAD e a área foliar individual, e favoreceu o status hídrico dos cafeeiros sob restrição hídrica. As plantas jovens de café, sem restrição hídrica e tratadas com o regulador vegetal, tiveram maior retenção foliar e índice SPAD, e menor área foliar individual. A aplicação de paclobutrazol em concentrações elevadas resultou em plantas mais compactas. A restrição hídrica proporcionou menor área foliar total, número de ramos e massa seca dos cafeeiros.

Atualmente está sendo bastante utilizada, principalmente no Reino Unido, a metodologia de ensino STEAM, que é um acrônimo de Ciência, Tecnologia, Engenharia, Artes e Matemática. Para utilizar essa metodologia ao ensinar, é preciso estabelecer inter-relações entre essas cinco áreas do conhecimento. Nesse sentido, o presente estudo é fruto das discussões realizadas e da atividade solicitadas pela disciplina Tendências e abordagens de pesquisas em ensino de Ciências e Matemática, que ocorreu em julho de 2017, ofertada pelo Programa de Doutorado em Educação em Ciências e Matemática (PPGECEM/REAMEC). Seu objetivo foi conjecturar possibilidades de problematizações STEAM na Atividade de Campo durante uma visita ao Parque Mãe Bonifácia, em Cuiabá-MT. Foram realizadas observações não estruturadas com intuito de identificar possibilidades didáticas, por meio de elementos, estruturas e lugares do referido parque. As possibilidades de problematizações encontradas foram as estruturas construídas no parque, sendo as cabanas de descanso, a estátua que faz referência à matriarca do parque e o mirante. Esta última já não existe mais devido a comprometimento em sua conjuntura estrutural, mas pode ser trabalhado devido registros em sites de notícias locais e nacionais. Logo, o estudo mostrou ser possível utilizar a metodologia STEAM para favorecer a construção de conhecimentos de forma inter-relacionada.

Published: November 2017

O presente artigo é uma revisão bibliográfica que tem por objetivo refletir acerca da importância da formação pedagógica para o magistério no ensino superior e da profissionalidade docente, desencadeando base teórica que afirme a importância e a pertinência do conhecimento pedagógico-didático em seu caráter mediador para a prática pedagógica no Bacharelado em Ciências Contábeis. A abordagem teórica que contextualiza a docência no ensino superior revela como, historicamente, no ensino da Contabilidade, os professores são recrutados entre profissionais de sucesso na profissão cuja maioria está despreparada para o magistério, e sem o domínio das questões pedagógicas, há ausência dos conhecimentos pedagógicos necessários ao exercício da docência na Educação Superior. Atualmente, essa problemática foi agravada pelo fato de que, com a expansão desse nível de ensino, além de profissionais não habilitados para o magistério, estão ingressando os que também não possuem experiência profissional na área contábil, restringindo os conhecimentos ao currículo do curso de formação inicial. A reflexão teórica ressalta a complexidade da docência, que envolve diversas dimensões: humana, técnica, política e ética, e a necessidade do desenvolvimento da profissionalidade docente que pressupõe consciência, compreensão e conhecimento. A fim de assimilar os papéis requeridos para os professores na configuração e no desenvolvimento do currículo no Ensino Superior, entre as conclusões deste estudo está a legitimação da natureza teórico-prática da profissão docente que pressupõe a existência de um corpo de conhecimentos em função dos quais se questione a ação docente.

Seasonal influenza is widely regarded as a continuing threat to public health, with vaccination remaining the principal measure of prophylaxis. In 2003, the World Health Organization issued targets for influenza vaccine coverage in the elderly of at least 50% by 2006 and 75% by 2010, endorsed by the European Parliament in two resolutions in 2005 and 2006. However, a number of European public health systems lack mechanisms to assess progress in influenza vaccine uptake. The European Vaccine Manufacturers group (EVM) undertook a Europe-wide survey of vaccine distribution over the last five seasons (between 2003 and 2008) to provide baseline data from which vaccination trends may be extrapolated. The survey data showed that the dose distribution level per capita in the 27 EU countries increased from 17% in 2003-4 to 20% in 2006-7; this growth was not maintained in the season 2007-8. Even without information on which age or risk groups received the vaccine, an immunisation rate of approximately 20% of the whole population falls short of the public health goal by more than half: an estimated 49% of the total population fall into risk groups recommended to receive the influenza vaccine in Europe. These data provide the only systematic review of vaccine dose distribution across Europe from a uniform source. Although they represent an important baseline parameter, age- and risk-group related vaccine uptake data with sufficient detail are needed to assist public health policy decision making, immunisation planning and monitoring. In light of this situation, and to support the improvement of immunisation rates across the EU, EVM aims to provide dose distribution data for each influenza season to assist Member States in the implementation of local immunisation policies.

An outbreak of influenza A(H1N1)v in a boarding school in South East England, May-June 2009
Authors: Smith A , Coles S , Johnson S , Saldana L , Ihekweazu C , O’Moore É
Published: November 2017

An outbreak of influenza A(H1N1)v was confirmed in May and June 2009 in a boarding school in South East England involving 102 symptomatic cases with influenza-like illness. Influenza A(H1N1)v infection was laboratory-confirmed by PCR in 62 pupils and one member of staff. Control measures were implemented as soon as a case was confirmed and included school closure, active case finding and treatment as well as post-exposure prophylaxis offered to the entire school population. Had the outbreak had been detected earlier, the school closed earlier and prophylaxis commenced after the initial cases were detected, we may have seen lower levels of transmission.

Published: November 2017

As of 7 July 2009, a total of 158 laboratory-confirmed cases of influenza A(H1N1)v were reported in Italy, from half of the 21 Italian regions. To date all cases have had symptoms consistent with seasonal influenza and no severe or fatal cases have been reported. An active surveillance of cases has been set up in Italy in order to undertake appropriate measures to slow down the spread of the new virus. This report describes the routine and enhanced surveillance currently ongoing in Italy.

We report here an update on human cases of West Nile virus (WNV) infection in Veneto region, northeastern Italy. In addition to two cases of WNV neuroinvasive disease notified through a surveillance programme started in September 2008, further four cases were retrospectively identified (in May 2009) by investigating patients with aseptic meningoencephalitis of unknown aetiology occurring in Veneto region in June-September 2008. All six patients had symptom onset in August-September 2008 and were resident in a wetland area close to the Po river delta in Rovigo province. Further five cases of asymptomatic WNV infection, including four residents of the same area in Rovigo, were identified in a seroprevalence study in farm workers from Veneto region. To date, no human cases have been notified in 2009.
A preliminary analysis of the epidemiology of influenza A(H1N1)v virus infection in Thailand from early outbreak data, June-July 2009

As the influenza A(H1N1)v pandemic unfolds globally, it is vital to monitor closely for signals of change in the current patterns of transmission. We estimate the basic reproduction ratio for A(H1N1)v virus in Thailand and propose a method to keep track of the actual case count notwithstanding the exponential growth rate.
Description of the early stage of pandemic (H1N1) 2009 in Germany, 27 April-16 June 2009
Authors: Novel influenza A(H1N1) investigation team
Published: November 2017

We report characteristics of the early stage of the pandemic (H1N1) 2009 in Germany. Until 16 June 2009, 198 confirmed cases were notified. Almost half of the cases (47%) were imported, mostly from Mexico and the United States. About two thirds of indigenous cases were outbreak-related (with two large school-associated outbreaks, n=74). According to our results Germany is still in the early stage of the pandemic with limited domestic transmission.

Preparedness planning for two large mass gatherings events were considered in Serbia in the context of pandemic influenza (H1N1) 2009. Planning included approaches to prevention, detection and response in order to mitigate the situation at this early stage of the epidemic in Serbia. Cases of influenza A(H1N1)v were identified nationally immediately prior to the mass gatherings but also identified in association with both events, as expected in the context of the pandemic situation. This article describes the experiences of planning and the epidemiological situation during the period of the mass gathering events.
Do men who have sex with men use serosorting with casual partners in France? Results of a nationwide survey (ANRS-EN17-Presse Gay 2004)

We examined whether men who have sex with men (MSM) in France have adopted serosorting with their casual partners, serosorting being one strategy to reduce the risk of HIV transmission. We expected to see the same predictors of this practice with casual partners in France as in other similar MSM communities (HIV-seropositive, Internet dating). Data from a cross-sectional survey was used, based on a self-administered questionnaire conducted among readers of the gay press and users of gay websites in 2004. The study population consisted of MSM who reported their HIV status, as well as the practice of unprotected anal intercourse (UAI) with a casual partner at least once during the previous 12 months. Among 881 respondents included in the analysis, 195 (22%) had practiced serosorting: 14% among HIV-seropositive men and 26% among HIV-seronegative men. Serosorting was independently associated with the use of cruising venues (AOR 0.28, p=0.001) and Internet dating (AOR 2.16, p=0.051) among HIV-seropositive men, whereas it was independently associated with the use of cruising venues (AOR 0.59, p=0.013) and the fact of having less partners (AOR 1.50, p=0.046) among HIV-seronegative men. Serosorting requires an up-to-date knowledge of HIV serostatus for MSM and their UAI casual partners, and does not prevent from acquiring other sexually transmitted infections. Prevention campaigns are needed to underline the risks associated with serosorting.

We report the successful control of an outbreak caused by imipenem-resistant VIM-1-producing Klebsiella pneumoniae (IR-Kp) in France. This outbreak occurred in a care centre for abdominal surgery that includes a 15-bed liver intensive care unit and performs more than 130 liver transplantations per year. The index case was a patient with acute liver failure transferred from a hospital in Greece for urgent liver transplantation who was carrying IR-Kp at admission as revealed by routine culture of a rectal swab. Infection control measures were undertaken and included contact isolation and promotion of hand hygiene with alcohol-based hand rub solution. Nevertheless, secondary IR-Kp cases were identified during the six following months from 3 December 2003 to 2 June 2004. From 2 June to 21 October, extended infection control measures were set up, such as cohorting IR-Kp carriers, contact patients and new patients in distinct sections with dedicated staff, limiting ward admission, and strict control of patient transfer. They led to a rapid control of the outbreak. The global attack rate of the IR-Kp outbreak was 2.5%, 13% in liver transplant patients and 0.4% in the other patients in the care centre (p<0.005). Systematic screening for IR-Kp of all patients admitted to the care centre is still maintained to date and no secondary IR-Kp case has been detected since 2 June 2004.
