On-site extraction using a 3D printed device coated with Zn/Co-ZIF-derived carbon followed by an on-line SIA-HPLC-FL system for fluoroquinolones determination in wastewater

A 3D printed device covered with Zn/Co-ZIF-derived carbon allows the on-site extraction of fluoroquinolones (FQs) from wastewater, avoiding the sample transportation to the laboratory, and the subsequent elution, separation and determination using an on-line flow system based on sequential injection analysis (SIA) coupled to HPLC-FL. Several parameters that affect the extraction efficiency and desorption were optimized including the sorption phase immobilization technique on the 3D device, extraction time, pH effect, sample volume as well as the type of eluent, eluent volume, and flow rate. Under optimum conditions, detection limits of 3-9 ng L-1 were achieved for norfloxacin, ciprofloxacin, danofloxacin, enrofloxacin and difloxacin. The precision expressed as relative standard deviation (%RSD, n = 3), showed intraday and interday ranges of 1.5-5.3% and 2.8-5.7%, respectively, demonstrating a good precision of the proposed methodology. To assess matrix effects and accuracy of the proposed method in real samples, recovery studies were performed without and with FQs spiked at different concentrations (0.5-10 μg L-1) to wastewater samples, showing good recoveries in the range of 91-104%. The results allow to confirm the applicability of MOF-derived carbons as adsorbents for on-site extraction, and the satisfactory separation and quantification of FQs by a SIA-HPLC-FL on-line system after their desorption with small eluent volumes.

Interaction among health workers and trans men: Findings from a qualitative study in Chile

PURPOSE

To explore trans men's access and use of healthcare services in Chile, based on the experiences of the trans men themselves, as well as of healthcare professionals.

METHODS

A qualitative study with an ethnographic approach was carried out with 30 participants: 14 trans men and 16 healthcare professionals. Semi-structured one-on-one interviews with open-ended questions were used to collect the data. A thematic analysis was carried out with the NVivo Software.

RESULTS

Three main themes were identified: (1) failures in the recognition of trans identity, (2) challenges with patient-centered care, and (3) use of other ("non-trans") health services.

CONCLUSIONS

The results suggest that not all transition processes are the same, individuals seek different ways; therefore, it is necessary to consider different body types and identities when planning programs and care for men in transition. Moreover, the accompaniment provided during the gender transition process should contemplate emotional and mental support.

CLINICAL RELEVANCE

The study outlines the need for all healthcare professionals to have training and knowledge about the transgender population, regardless of whether they are part of the teams supporting gender transition processes. The role of nurses and the contributions that can be made from nursing discipline in this research field are fundamental.

Syndemic Conditions and Their Association with HIV/STI Sexual Risk Behaviors Among Transgender Women and Cisgender Men Sex Workers in Catalonia: The SexCohort Project

BACKGROUND

Transgender women and cisgender men sex workers are vulnerable to HIV and sexually transmitted infections (STIs). This study aimed to explore in depth the prevalence of syndemic conditions and their association with the sexual risk behaviors for HIV/STI acquisition in cis men and trans women sex workers in Barcelona (Catalonia, Spain).

METHOD

We conducted a study between 2014 and 2018 to determine whether syndemic conditions (frequent alcohol consumption and polydrug use (> 2) during sex with clients; experience of violence; and lack of healthcare access) are associated with HIV/STI sexual risk behaviors. A "syndemic index" was calculated based on the cumulative number of syndemic conditions (0 to 4).

RESULTS

In the last year (2018), 78.8% of cisgender men and 68.1% of transgender women reported at least one syndemic condition. The most prevalent syndemic factor in both cisgender men and transgender women was violence (38.8% and 43.6% respectively). In multivariable analysis, an association was found between condomless anal sex and violence (aOR = 1.81), and frequent alcohol consumption and violence with reporting > 10 clients/week (aOR = 2.73 and 1.88, respectively). The higher the number of syndemic factors, the greater probability of having > 10 clients/week and reporting condomless anal sex with clients.

CONCLUSION

Psychosocial conditions have a syndemic effect on risky sexual behaviors highlighting the need for a more holistic approach to HIV/STI prevention targeting these populations.

Expert review and consensus on the t2t management of hereditary angioedema: from the scientific evidence to clinical practice

BACKGROUND

Hereditary angioedema with C1 inhibitor deficiency (HAE-C1INH) is a rare disease characterized by swelling episodes. It affects quality of life (QoL) and can be lethal, when involving upper airways. Treatment is individualized, with therapeutic options including on-demand treatment (ODT), and short- and long-term prophylaxis (STP, LTP). However, available guidelines are not always clear about treatment selection, its goals or assessment of goal achievement.

OBJECTIVE

To review the available evidence for the management of HAE-C1INH and build a Spanish expert consensus to steer HAE-C1INH management towards a treat-to-target (T2T) approach, while addressing some of the unclear aspects of the Spanish guidelines.

METHODS

We reviewed the literature on the management of HAE-C1INH with a T2T approach, focusing on: 1) treatment selection and goals; and 2) available tools to assess goal achievement. We discussed the literature based on clinical experience and drew up 45 statements on undefined management aspects. A panel of 53 HAE experts validated the statements through a two-round Delphi process.

RESULTS

The goals for ODT and STP are minimizing the morbidity and mortality of attacks, and preventing attacks caused by known triggers, respectively, while the main goal of LTP is to decrease the rate, severity and duration of attacks. Furthermore, when prescribing, clinicians should consider the reduction in adverse events, while increasing patient QoL and satisfaction. Appropriate instruments for assessing goal achievement have also been indicated.

CONCLUSIONS

We provide recommendations on previously unclear aspects of HAE-C1INH management with ODT, STP and LTP, focusing particularly on clinical and patient-oriented goals.

Impact of the COVID-19 Health Crisis on Trans Women and Cis Men Sex Workers in Spain

The objective of the study was to describe the impact of the COVID-19 pandemic on sex workers in accessing health and social services. A qualitative study was conducted using semi-structured interviews with 29 participants in Barcelona, Spain. Data were analyzed using thematic analysis. Four themes were identified: (1) impact of COVID-19 on physical/mental health, (2) barriers and facilitators to health/social service access, (3) health decision-making, and (4) suggestions for future pandemic situations. Barriers to accessing health services were structural. Non-governmental organization support was the main facilitating factor. A person-centered, intersectional approach is suggested for future practice, considering co-occurring syndemic factors.

Perceptions of COVID-19 Maternal Vaccination among Pregnant Women and Healthcare Workers and Factors That Influence Vaccine Acceptance: A Cross-Sectional Study in Barcelona, Spain

COVID-19 is associated with poor maternal and pregnancy outcomes. COVID-19 vaccination is recommended in Spain, yet vaccination rates in pregnancy are suboptimal. This study investigates the perceptions of pregnant women and healthcare workers (HCW) regarding COVID-19 vaccination. A web-based cross-sectional quantitative study was conducted in 2021–2022 among 302 pregnant women and 309 HCWs in the Catalan public health system. Most pregnant women (83%) and HCWs (86%) were aware of COVID-19 maternal vaccines. The recommendation of the COVID-19 vaccination by an HCW was identified as the greatest facilitator for maternal vaccine uptake, while the fear of harming the foetus was the most significant barrier reported for rejecting vaccination. HCWs recognised they received limited information and training about COVID-19 vaccination in pregnancy, which hindered them from providing informed recommendations. This study highlights that information and education on COVID-19 vaccines to pregnant women and health professionals are pivotal to ensuring informed decision-making and increasing vaccine uptake.

High HIV/STI prevalence among cisgender men and transgender women sex workers attending community-based centres in Barcelona, Spain: The Sweetie Project

Background

The aim of this study was to describe the socio-demographics, and the sexual and health-seeking behaviours of cisgender men and transgender women sex workers (M & TWSW) attending community-based organisations (CBOs) in Barcelona, Spain, as well as to estimate the prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), Chlamydia Trachomatis (CT) and Neisseria gonorrhoeae (NG) among them at different anatomical sites.

Methods

The Sweetie Project was a community-based cross-sectional study of 147 M & TWSW recruited in two CBOs in Barcelona between 2017 and 2018. A nurse collected biological samples from rectum, pharynx and urethra from the subjects at each CBO and the participants self-completed an epidemiological questionnaire.

Results

The highest prevalence observed was for HIV infection (25.3%) followed by bacterial STIs (NG 19.2% and CT 10.3%). The most prevalent anatomical site was pharyngeal (17.7%) followed by rectal (13.8%). More than half of participants who had a pharyngeal infection presented an isolated pharyngeal infection (57.7%) and half of those who had a rectal or urethral infection presented an isolated infection respectively. The seroprevalence of HCV and HBV was 2.4% and 34.2% respectively. There was a poor but statistically significant correlation between HIV and rectal CT infection ( r = 0.31), previous exposure to HCV ( r = 0.27) or self-reported STI ( r = 0.23), as well as between previous exposure to HCV and rectal CT ( r = 0.21) or self-reported STI ( r = 0.20).

Discussion

The Sweetie Project confirms the high burden of HIV and bacterial STIs among a sample of M&TWSW recruited in CBOs and reinforces the need to routinely screen them at all exposed anatomical sites.

Psychological Wellbeing, Dyadic Adjustment, and Parental Stress among Spanish Families during the COVID-19 Outbreak

Due to COVID-19, many countries, like Spain, imposed lockdown on the entire population to prevent the virus from spreading. The purpose of this exploratory study is to investigate the severity of psychological symptoms, dyadic adjustment, and parental stress of parents during the first three weeks of the outbreak. It also aims to identify several risk factors that contribute to this distress. A total of 727 parents completed a form on an online platform with sociodemographic data, BSI- 18, EAD-13, and the Spanish version of the PPS. Linear regression analyses were used to explore the significant associations between the sample characteristics (sociodemographic variables and their lockdown circumstances) and parents' psychological symptoms, dyadic adjustment, and parenting stress level during the COVID-19 epidemic. Most parents maintained good emotional, personal, conjugal, and family stability; however, female gender, not living with the partner, having a child with a mental disorder and were unable to balance the work and family lives were significantly associated with greater psychological distress. Being receiving psychiatric or psychological treatment has also been associated with poorer psychological and partner adjustment during the outbreak. It is essential to continue researching the impact of lockdowns on families so that, both the government and public health authorities, can offer resources to the most vulnerable families.

Polarimetric data-based model for tissue recognition

We highlight the potential of a predictive optical model method for tissue recognition, based on the statistical analysis of different polarimetric indicators that retrieve complete polarimetric information (selective absorption, retardance and depolarization) of samples. The study is conducted on the experimental Mueller matrices of four biological tissues (bone, tendon, muscle and myotendinous junction) measured from a collection of 157 ex-vivo chicken samples. Moreover, we perform several non-parametric data distribution analyses to build a logistic regression-based algorithm capable to recognize, in a single and dynamic measurement, whether a sample corresponds (or not) to one of the four different tissue categories.

[Health status among immigrant in Catalonia from a gender perspective: PELFI project]

OBJECTIVE

The objective of the study is to assess the health status of immigrant men and women from non-EU countries living in the Metropolitan Area of Barcelona (Catalonia, Spain) and to identify the social determinants of health from a gender perspective.

METHOD

Cross-sectional analysis from a cohort of immigrant families recruited in Badalona and Santa Coloma de Gramenet, in Spain (PELFI cohort). In 2015-2016, 167 immigrants answered the baseline epidemiological questionnaire and the 5-level EuroQol instrument (EQ-5D) which measures health status. To identify health determinants, Tobit models were constructed to the EQ-5D index.

RESULTS

Women rated poorer self-perceived health (p=0.005). To be diagnosed with and illness was only associated with poor self-perceived health among men (p<0.05). Length of residence, domestic work, and especially double workload deteriorated women's health. After adjusting models by demographics and social determinants, permanent administrative status (-0.136; p=0.015) and social support (0.182; p=0.02) were associated with health status in both sexes. To have a job was associated with better health only in men.

CONCLUSIONS

Non-EU immigrants living in the Metropolitan Area of Barcelona are a socially vulnerable group of population and present inequalities in health by sex. Social support and occupation are key factors of their health status. Interventions to reduce immigrant vulnerabilities and inequalities in health should promote their social inclusion and cohesion from a gender perspective.

Impact of systematic advanced care planning in lung cancer patients: A prospective study

BACKGROUND

End-of-life (EOL) communication is crucial, particularly for cancer patients. While advanced care planning is still uncommon, we sought to investigate its impact on care intensity in case of organ failure in lung cancer patients.

METHODS

We prospectively included consecutive lung cancer patients hospitalised at the Grenoble University Hospital, France, between January 1, 2014 and March 31, 2016. Patients could be admitted several times and benefited from advanced care planning based on three care intensities: intensive care, maximal medical care, and exclusive palliative care. Patients' wishes were addressed.

RESULTS

Data of 739 hospitalisations concerning 482 patients were studied. During the three first admissions, 173 (25%) patients developed organ failure, with intensive care proposed to 56 (32%), maximal medical care to 104 (60%), and exclusive palliative care to 13 (8%). Median time to organ failure was 9 days [IQR 25%-75%: 3-13]. All patients benefited from care intensity that was either equal to or lower than the care proposed. Specific wishes were recorded for 158 (91%) patients, with a discussion about EOL conditions held in 116 (73%).

CONCLUSIONS

In case of organ failure, advanced care planning helps provide reasonable care intensity. The role of the patient's wishes as to the proposed care must be further investigated.

CLINICAL TRIAL REGISTRATION

The study was registered at www.ClinicalTrials.gov with the identifier NCT02852629.

[Concomitant use of nivolumab and immunosuppressants in a renal transplant patient]

INTRODUCTION

Immune-checkpoint inhibitors have been approved for first and second line treatments of metastatic non-small cell lung cancer based on the results of several phase III trials. Patients with organ transplantation were excluded from these studies because checkpoint inhibitors could activate allo-reactive T cells leading to acute graft rejection.

CASE REPORT

A 71-year-old Caucasian-male was diagnosed with stage IV pulmonary adenocarcinoma with multiple metastases, without molecular alteration and negative PD-L1 status. He had a left kidney transplant, and his immunosuppressive regimen consisted of sirolimus and mycophenolate mofetil. After failure of two therapeutic lines (carboplatin-paclitaxel and erlotinib) a multidisciplinary oncology meeting with the nephrologist started third line treatment with nivolumab 3mg/kg every 15 days, with no modification of the immunosuppressive treatment. The patient received a total of 14 injections of nivolumab with stable disease but treatment was discontinued due to acute rejection of the transplanted kidney 6 months later, without need for dialysis. The patient died of a chylothorax related to progression of the tumour 12 months after initiation of nivolumab.

CONCLUSION

Immune checkpoint inhibitors are a potential treatment for solid organ transplant patients despite the risk of graft rejection.

[Hybrid radiotherapy machines: Evolution or revolution?]

The arrival of new hybrid radiotherapy machines with MRI or PET is announced as a milestone in radiotherapy management. Based on recent literature, we will describe the contribution of each of these modalities and the technological challenges that have already been or are still to be addressed.

[The role of biomedical interventions in HIV prevention: Pre-exposure Prophylaxis (PrEP)]

HIV infection remains an important public health problem worldwide. The traditional preventive measures, such as sexual education, screening, and early antiretroviral treatment initiation, despite having shown their effectiveness, are not enough to control new infections. In this context, Pre-Exposure Prophylaxis (PrEP) has been investigated as a preventive measure. Currently, it has been extensively documented that the administration of antiretroviral treatment in an HIV exposed, but not infected population, could reduce the risk of transmission without significant drawbacks. Despite its high efficacy for HIV prevention, the use of PrEP remains a controversial measure, particularly its cost-effectiveness. For this reason, the access to PrEP is not available for all the HIV risk groups. Therefore, and based on the evidence found, the current approach must be the repercussions of not to implement PrEP, more than its cost or its effectiveness.

[Emergency room management of patients with lung cancer and organ failure]

BACKGROUND

When patients with lung cancer present to the emergency department with organ failure the question of admission to intensive care has to be considered. Our aim is to describe the process leading to the proposed management.

METHODS

Retrospectively, all patients admitted to the emergency room between December 2010 and January 2015 with a diagnosis of ICD-10 C34.9 (lung cancer) were reviewed. Those with at least one organ failure were included.

RESULTS

The records of 561 patients were reviewed, 79 (14%) had at least one organ failure. The majority of these patients received maximal medical care (59%), 25% exclusive palliative care, and 15% intensive care. Performance status, metastatic status and efficacy of anti-tumor treatment were recorded in the emergency medical record in 20%, 66% and 74% of cases, respectively. An opinion was obtained from the oncologist in 44% of cases and from the intensivist in 41% of cases. No external advice was provided in 27% of cases.

CONCLUSION

In the majority of cases, the decision on the intensity of care to be provided to patients with lung cancer and organ failure was made in a collective manner.

Les avancées dans la prise en charge des cancers bronchopulmonaires : ce qui change pour le réanimateur

Le cancer bronchopulmonaire (CBP) est la première cause de mortalité par cancer en France et dans le monde, mais son pronostic tend à s’améliorer depuis une dizaine d’années grâce à de nouvelles classes de traitements : l’immunothérapie et les thérapies ciblées. L’immunothérapie stimule le système immunitaire afin d’engendrer une réponse antitumorale. Ces molécules peuvent être prescrites chez la plupart des patients avec un CBP non à petites cellules (CBNPC) métastatique et entraînent parfois des réponses tumorales majeures et durables pouvant dépasser les 24 mois. Toutefois, cette efficacité concerne entre 20 et 50 % des patients selon la ligne de traitement. Les thérapies ciblées sont des traitements oraux visant les cellules tumorales porteuses d’anomalies génétiques spécifiques (addictions oncogéniques) et intéressent moins de 15 % des patients avec CBNPC, majoritairement les non-fumeurs. Les deux principales sont les mutations du gène de l’epithelial growth factor receptor (EGFR) et les réarrangements d’anaplastic lymphoma kinase (ALK). Ces anomalies peuvent être diagnostiquées en quelques jours, parfois sur un prélèvement sanguin (biopsie liquide pour détecter les mutations EGFR). Les thérapies ciblées améliorent la survie globale des patients dont la médiane dépasse les 30 mois. Toutefois, ces deux classes de traitement entraînent des toxicités spécifiques, fréquentes mais souvent bénignes. Les hospitalisations en réanimation des patients porteurs de CBNPC sont croissantes. L’amélioration du pronostic de ces patients est à prendre en compte lors de la discussion d’admission en réanimation sans conduire à des prises en charge déraisonnables.

Community-based screening of hepatitis C with a one-step RNA detection algorithm from dried-blood spots: Analysis of key populations in Barcelona, Spain

Alternative strategies are required to enhance the diagnosis of silent hepatitis C virus (HCV) infections in key populations at risk. Among them, HCV prevalence and bio-behavioural data are scarce for HIV-negative men who have sex with men (MSM) and men and trans-women sex workers. We sought to describe and assess the potential benefits of a community-based one-step HCV screening and confirmatory strategy for these populations in Barcelona. The screening strategy based on a real-time RT-PCR assay for HCV-RNA detection in dried-blood spots (DBS) was validated and implemented in addition to an antibody point-of-care test in a community centre. HCV prevalence was assessed, and bio-behavioural data were collected. The molecular assay was precise, reproducible, sensitive and specific. Four HIV-negative MSM reported being currently infected (0.75% HCV self-reported prevalence). Implementation of DBS testing was easy, and acceptability was >95%, but no silent HCV case was diagnosed (N = 580). High-risk sexual practices and drug use for sex were reported frequently. HIV prevalence was 4.7% in MSM and 10% in sex workers. Self-reported prevalence of other STIs ranged from 11.3% to 36.2%. In conclusion, HCV-RNA testing in DBS showed a good performance, but the assessed one-step strategy does not seem beneficial in this setting. Although no silent HCV infections were detected, the observed high-risk behaviours and prevalence of other STIs suggest that HCV spread should be periodically monitored among these populations in Barcelona by means of behavioural surveillance, rapid antibody testing and molecular confirmation in DBS.

Mould and grass pollen allergy as risk factors for childhood asthma in Zaragoza, Spain

OBJECTIVE

Examine the prevalence of asthma and associated predictive factors in a group of 468 students.

PATIENTS AND METHODS

A descriptive, cross-sectional observational study in a randomly selected population of 468 children aged 10-12, in the city of Zaragoza. We used the ISAAC questionnaire on asthma completed by children under supervision of the investigators. We assessed the genetic risk (family history of asthma) and environmental risks. The risk for atopy was assessed by the presence of positive skin prick tests.

RESULTS

25.3% of the children had symptoms consistent with asthma in the city of Zaragoza. Among them 33.1% reported a history of asthma in close relatives (OR=1.78, p<0.001). The history of hospitalisations for lower respiratory tract illness was strongly associated with the presence of asthma (OR=6.72, p<0.0001). Positive skin tests to Alternaria (OR=2.00, p<0.0001) and grass pollen (OR=1.76, p<0.001) were predictors of asthma. 63.6% of asthmatic children had presented clinical rhinitis in the previous 12 months, compared with 32% of non-asthmatics, and this difference was statistically significant (OR=3.89, p<0.0001). 47% of asthmatics presented with or previously had eczema, whereas only 26.9% of non-asthmatics presented with or previously had these types of lesions (p<0.0001).

CONCLUSION

The following are predictors of asthma: History of hospital admissions for lower respiratory tract illness, presence of rhinitis and/or eczema, positive prick test for certain aeroallergens, especially Alternaria and grass pollen, and family history of asthma.

Bio-behavioural HIV and STI surveillance among men who have sex with men in Europe: the Sialon II protocols

BACKGROUND

Globally, the HIV epidemic continues to represent a pressing public health issue in Europe and elsewhere. There is an emerging and progressively urgent need to harmonise HIV and STI behavioural surveillance among MSM across European countries through the adoption of common indicators, as well as the development of trend analysis in order to monitor the HIV-STI epidemic over time. The Sialon II project protocols have been elaborated for the purpose of implementing a large-scale bio-behavioural survey among MSM in Europe in line with a Second Generation Surveillance System (SGSS) approach.

METHODS/DESIGN

Sialon II is a multi-centre biological and behavioural cross-sectional survey carried out across 13 European countries (Belgium, Bulgaria, Germany, Italy, Lithuania, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the UK) in community settings. A total of 4,966 MSM were enrolled in the study (3,661 participants in the TLS survey, 1,305 participants in the RDS survey). Three distinct components are foreseen in the study protocols: first, a preliminary formative research in each participating country. Second, collection of primary data using two sampling methods designed specifically for 'hard-to-reach' populations, namely Time Location Sampling (TLS) and Respondent Driven Sampling (RDS). Third, implementation of a targeted HIV/STI prevention campaign in the broader context of the data collection.

DISCUSSION

Through the implementation of combined and targeted prevention complemented by meaningful surveillance among MSM, Sialon II represents a unique opportunity to pilot a bio-behavioural survey in community settings in line with the SGSS approach in a large number of EU countries. Data generated through this survey will not only provide a valuable snapshot of the HIV epidemic in MSM but will also offer an important trend analysis of the epidemiology of HIV and other STIs over time across Europe. Therefore, the Sialon II protocol and findings are likely to contribute significantly to increasing the comparability of data in EU countries through the use of common indicators and in contributing to the development of effective public health strategies and policies in areas of high need.

High HIV incidence among men who have sex with men attending a community-based voluntary counselling and testing service in Barcelona, Spain: results from the ITACA cohort

OBJECTIVES

To identify the HIV incidence and its associated factors (AFs) of the ITACA, a community-based cohort of HIV-negative men who have sex with men (MSM) established in Barcelona, Spain from 2008 to 2011.

METHODS

Participants were men aged 18 years or older, having a negative HIV test result at baseline and agreeing to participate. Bio-behavioural data were collected by peers in each visit. HIV incidence rates using person-time measures and 95% CIs were calculated. Cox logistic regression models were used to identify AFs to seroconversion.

RESULTS

Over the period, 3544 participants with at least one follow-up visit or those who had a first visit no longer than a year prior to the date of data censoring were included in the analysis contributing 3567.09 person-year (p-y) and 85 MSM seroconverted for an overall HIV incidence of 2.4 per 100 p-y (95% CI 1.9 to 2.9) ranging from 1.21/100 (2009) to 3.1/100 p-y (2011). Independent AF included: foreign origin, having more than five HIV tests at baseline, reporting in the preceding 6 months the following: condomless anal sex with the last steady partner of unknown serostatus, more than 10 casual partners, condomless anal sex with casual partner, self-reported gonorrhoea and entered in the cohort in 2010 or 2011.

CONCLUSIONS

The ITACA cohort revealed a high and increasing HIV incidence among MSM, especially important among foreign-born men. The findings underscore the need to implement multilevel interventions for MSM taking into account different types of partners, cultural origins and the exposure to other sexually transmitted infections.

Suicidal Tendency Among Adolescents With Adjustment Disorder

Abstract. Background: Adolescents with adjustment disorder (AD) are at risk of presenting suicidal symptoms. Certain personality traits are linked to suicidal tendencies. There is a lack of information about the link between suicide and personality patterns in adolescents with AD. Aims: To identify the personality characteristics that predispose to or prevent the development of suicidal ideation and behavior among adolescents with AD. Method: We recruited 108 adolescents with AD at a public mental health center near Barcelona (Spain). They were administered the Inventario de Riesgo Suicida para Adolescentes (IRIS) to assess suicidal symptoms, as well as the Millon Adolescent Clinical Inventory (MACI) and the 16PF Adolescent Personality Questionnaire (16PF-APQ) to appraise personality features. Results: Doleful personality emerged as the principal risk for suicidal symptoms. The conforming personality pattern exerted a protective effect, and emotional stability was associated with low levels of suicidal tendencies. Among the Big Five factors, anxiety had the highest explanatory power for suicidal tendencies. Conclusion: Certain personality characteristics are associated with heightened or reduced risk of suicidal tendencies in adolescents with AD. Their identification is important for clinicians designing treatment programs for these patients.

Condom use among female sex workers in Catalonia: why do they use a condom, why don't they use it?

The present study, based on social representation theory (Moscovici, 1961), aimed to identify the social representation of condom use (CU) in a collective of female sex workers (FSW) in Catalonia, considering both their work and private life. It involved 124 FSW and combined both qualitative and quantitative methodologies. Results suggest that both CU and non-CU represent strategies that FSW use mainly when confronted by threats to things they consider important. In work life, where CU is widespread, the most important thing is health protection, and the threat is represented by sexually transmitted infections. In private life, where non-CU is widespread, the most important thing is that their relationships adhere to an idealized relationship model, based on love, trust, and sexual gratification; this model lies in contrast to the status of the women as FSW. The threats are represented by both partner infidelity and their FSW status (symbolic threats).

[Effectiveness of an integrated treatment for severe personality disorders. A 36-month pragmatic follow-up]

INTRODUCTION

Over the past 25 years, several studies have shown the efficacy of a number of psychological interventions for severe personality disorders. However, the generalizability of these positive results from long traditional research settings to more ordinary ones has been questioned, requiring a need for replication in pragmatic studies.

METHODS

This pragmatic study compares hospitalizations and Emergency Room visits before and during a 6-month therapeutic program for severe personality disorders, and at 36 months after starting it. The therapeutic program, which integrates several specific interventions within a coherent framework, was carried out in an ordinary clinical setting. Fifty-one patients, evaluated according DSM-IV criteria by using the Spanish version of the Structured Clinical Interview for Personality Disorders (SCID-II), were included.

RESULTS

The clinical characteristics showed a group of severely disturbed patients, of which 78.4% met criteria for borderline personality disorder. The percentage of patients hospitalized and visiting the Emergency Room, as well as the number of days of hospitalization and Emergency Room visits was significantly reduced during the treatment, and this improvement was maintained throughout.

CONCLUSIONS

An integrated treatment for severe personality disorders could be effective in preventing reliance on readmissions, or prolonged hospital stays, when it is implemented by clinicians in ordinary clinical settings.

Hepatitis C virus infection and its relationship to certain sexual practices in men-who-have-sex-with-men in Spain: results from the European MSM internet survey (EMIS)

OBJECTIVES

To compare sexual practices and risk behaviours between MSM who were first diagnosed with hepatitis C (HCV) in the previous 12 months and those who were never diagnosed; and, to identify factors associated with a diagnosis of HCV.

METHODS

The European-MSM-Internet-Survey (EMIS) was implemented for 3 months during 2010, mainly on websites for MSM. Data on socio-demographic characteristics, sexual behaviour, drug use, STI history, and other sexual health variables were collected. The Chi-square test and logistic regression analysis were used to analyse the data.

RESULTS

Data from 13,111 respondents were analysed. The proportion of MSM who had ever been diagnosed with HCV infection was 1.9% (n=250), and of those currently infected with the virus was 0.6% (n=78). The percentage of those first diagnosed in the last 12 months was 0.4% (n=46), of whom 70% were HIV-negative and 22% had HIV coinfection. Having a first diagnosis of HCV in the last 12 months was more common among HIV-positive than among HIV-negative MSM (0.9% vs 0.4%) and among MSM born abroad than among Spanish-born (0.7% vs 0.3%). MSM diagnosed with HCV in the last 12 months were more likely to have had: more than 10 sexual partners, sex abroad, receptive anal intercourse, insertive/receptive fisting, and unprotected anal intercourse with non-steady partners of unknown or discordant HIV-status. Likewise, they reported more frequent visits to sex-focused venues, higher drug use, as well as a higher proportion of STI diagnosis. In the multivariate model, visiting a public sex-focused venue, practicing receptive fisting, using erection enhancing medication and having a diagnosis of syphilis were independently associated with a first diagnosis of HCV in the last 12 months.

CONCLUSIONS

HCV infection does not seem to be restricted to HIV-infected MSM. Certain sexual behaviour (fisting, visiting sex-focused venues), drug use, and ulcerative STI seem to be associated with a diagnosis of HCV.

Undiagnosed HIV infection in a population of MSM from six European cities: results from the Sialon project

OBJECTIVES

The purpose of this article is to assess the distribution of undiagnosed HIV infection in men who have sex with men (MSM) in Southern and Eastern European countries, to describe the differences in epidemiology and behaviour between undiagnosed, diagnosed HIV-positive and HIV-negative MSM and to identify factors associated with undiagnosed HIV infection in the study population.

METHODS

A multi-centre biological and behavioural cross-sectional study was conducted in 2008. Time-location sampling was used to recruit men attending different venues. A self-administered questionnaire was completed and oral fluid samples were collected to estimate HIV prevalence.

RESULTS

HIV prevalence was 17% in Barcelona, 12% in Verona, 6% in Bratislava, 5% in Ljubljana, 5% in Bucharest and 3% in Prague while undiagnosed HIV infection was 47, 62, 67, 83, 85 and 57%, respectively. Diagnosed HIV-positive men reported more casual partners than HIV-negative MSM (mean: 19 and 9, respectively) (P < 0.001), and they were more likely to self-reported condyloma in the last year than undiagnosed HIV-positive and HIV-negative men (15, 1 and 3%, respectively) (P < 0.001). Factors associated with undiagnosed HIV infection included attending sex-focused venues (OR = 2.49), reporting syphilis in the previous 12 months (OR = 2.56), using poppers at last sexual intercourse (OR = 3.36) and having had an HIV test in the previous year (OR = 2.00).

CONCLUSIONS

Many HIV infections remain undiagnosed, and there is evidence of the persistence of frequent risk behaviours and sexually transmitted infections (STI) despite knowledge of HIV-positive status, emphasising the need for a multidimensional approach to HIV/STI prevention. Access to HIV testing should be considered a priority in prevention programs targeted at MSM, especially in Eastern Europe.

Is nuchal translucency a useful aneuploidy marker in fetuses with crown-rump length of 28-44 mm?

OBJECTIVE

To investigate whether increased nuchal translucency (NT) in fetuses with a crown-rump length (CRL) below 45 mm needs to be re-evaluated at a later stage, or whether the early NT measurement can be used effectively as an aneuploidy marker.

METHODS

This was a prospective cohort study including all singleton fetuses with a CRL between 28 and 44 mm, scanned in our center during 2002-2012. The CRL, NT, fetal karyotype (when available) and pregnancy outcome were recorded. NT reference ranges were constructed using the Lambda-Mu-Sigma (LMS) method in non-referred pregnancies after exclusion of chromosomal anomalies. The 95(th) percentile was used to calculate detection rates for chromosomally abnormal fetuses.

RESULTS

NT was successfully measured in 643 of 672 fetuses with a CRL of 28-44 mm. Subsequent cytogenetic analysis revealed 11 cases of trisomy 21, 14 cases of trisomy 13 or 18, three cases of monosomy X, three sex trisomies, three triploidies and 12 balanced anomalies. NT was above the 95(th) percentile in 64% of the fetuses with trisomy 21, in 71% with trisomy 13 or 18 and in all three cases of monosomy X.

CONCLUSION

NT appears to be useful as a marker for the early detection of fetal trisomies at 9-10 weeks' gestation (28-44 mm CRL).
