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.

Expert Review and Consensus on the Treat-to-Target Management of Hereditary Angioedema: From 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 fatal when the upper airways are involved. 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 the selection of treatment, the goals of treatment, or how achievement of these goals is assessed. OBJECTIVE: To review available evidence for the management of HAE-C1INH and build a Spanish expert consensus to steer management towards a treat-to-target approach, while addressing some of the less clear aspects of the Spanish guidelines. METHODS: We reviewed the literature on the treat-to-target management of HAE-C1INH, focusing on treatment selection and goals and the tools available to assess whether the goals have been achieved. 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 2-round Delphi process. RESULTS: The goals for ODT and STP are to minimize the morbidity and mortality of attacks and to prevent 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 effects, while increasing patient QOL and satisfaction. Appropriate instruments for assessing achievement of treatment goals are also indicated. CONCLUSIONS: We provide recommendations on previously unclear aspects of HAE-C1INH management with ODT, STP, and LTP, focusing on clinical and patient-oriented goals.

Major differences in the larval anatomy of the digestive and excretory systems of three Oestridae species revealed by micro-CT.

Oestrid flies (Diptera: Oestridae) do not feed during the adult stage, so they depend on an efficient assimilation and storage of nutrients during their parasitic larval stage. We describe the general morphology and provide volumetric data for the digestive and excretory organs of the three larval instars of the nasal bot fly Oestrus ovis L., using micro-computed tomography. The size of the digestive and excretory organs greatly increased across larval instars. In all instars, the two salivary glands were remarkably large and formed a 'glandular band' by coming together, but without lumina uniting, at their posterior ends. The distal region of the anterior Malpighian tubules was greatly enlarged and full of highly radio-opaque concretions. Moreover, the anatomy of O. ovis third-instar larva was compared to that of two species of, respectively, similar and different feeding habits: Cephenemyia stimulator (Clark) and Hypoderma actaeon Brauer. Whereas the general morphology and arrangement of the digestive and excretory systems of C. stimulator was similar to that of O. ovis, some differences were observed in H. actaeon: a swollen anterior region of the midgut, salivary glands shorter and not forming a 'band' and anterior Malpighian tubules narrowly uniform throughout their entire length.

Internal morphological changes during metamorphosis in the sheep nasal bot fly, Oestrus ovis.

During the larval stage, oestrid flies (Diptera: Oestridae) are obligate parasites, whereas during the adult stage they are free-living and do not feed. Like other cyclorrhaphous flies, oestrids undergo metamorphosis inside an opaque puparium, formed by the contracted and hardened cuticle of the third-instar larva. The present study documents the internal morphological changes taking place during metamorphosis of the sheep nasal bot fly, Oestrus ovis L., using non-invasive, micro-CT-based virtual histology and provides quantitative data of volumetric changes in specific organs. Virtual histological sections allowed visualisation of the progression and completion of the apolyses, which delimit the different intra-puparial stages, and the connection to the tracheal system of a large gas bubble, which plays an essential role during early metamorphosis. Overall, our results show that the sequence of morphological and volumetric changes in tissues and organs is similar to those found in other cyclorrhaphous flies, but they also reveal developmental differences that result in an adult vestigial digestive tract. Future studies could develop non-invasive, reliable methods for aging the intra-puparial forms of different oestrid species of veterinary importance, based on both qualitative and quantitative markers, thus improving our knowledge of their development and the efficiency of control strategies.

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.

Micro-computed tomography visualization of the vestigial alimentary canal in adult oestrid flies.

Oestrid flies (Diptera: Oestridae) do not feed during the adult stage as they acquire all necessary nutrients during the parasitic larval stage. The adult mouthparts and digestive tract are therefore frequently vestigial; however, morphological data on the alimentary canal in adult oestrid flies are scarce and a proper visualization of this organ system within the adult body is lacking. The present work visualizes the morphology of the alimentary canal in adults of two oestrid species, Oestrus ovis L. and Hypoderma lineatum (de Villiers), with the use of non-invasive micro-computed tomography (micro-CT) and compares it with the highly developed alimentary canal of the blow fly Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae). Both O. ovis and H. lineatum adults showed significant reductions of the cardia and the diameter of the digestive tract, an absence of the helicoidal portion of the midgut typical of other cyclorrhaphous flies, and a lack of crop and salivary glands. Given the current interest in the alimentary canal in adult dipterans in biomedical and developmental biology studies, further understanding of the morphology and development of this organ system in adult oestrids may provide valuable new insights in several areas of research.

Differences between migrants and Spanish-born population through the HIV care cascade, Catalonia: an analysis using multiple data sources.

Migrants are considered a key group at risk for HIV infection. This study describes differences between migrants and the Spanish-born population as they progress through the HIV care cascade in Catalonia, Spain. This study found that among people reached by prevention activities, migrants had a higher number of barriers to access HIV testing services than Spanish-born people, driven primarily by shared risk factors. Between 2001 and 2013, 9829 new HIV diagnoses were reported in Catalonia, the proportion of migrants increasing from 24% in 2001 to 41% in 2013. Compared with Spanish-born people, migrants had a higher proportion of women at diagnosis (24·6% vs. 16·7%), and were younger (median age of 33 vs. 37). The most frequent at-risk population was MSM (men who have sex with men) in both migrants and Spanish-born people, (40% and 43%, respectively), although there were significant differences by region of origin. People from sub-Saharan Africa had the highest proportion of late diagnosis (63·7%). Compared with the Spanish-born population, migrants on follow-up had a lower proportion of people on antiretroviral therapy (ART) (93·7% vs. 90·8%, P < 0·001) and with viral suppression (87·2% vs. 82·9%, P < 0·001). Migrants have higher number of barriers to access HIV testing services, lower retention rates and proportions on ART as compared with Spanish-born people, these differences not being uniform between migrants from different regions.

Awareness of Pre-exposure Prophylaxis for HIV, Willingness to Use It and Potential Barriers or Facilitators to Uptake Among Men Who Have Sex with Men in Spain.

There is a lack of data on pre-exposure prophylaxis (PrEP) effectiveness in Spain. We described the awareness of and willingness to use PrEP and examined potential barriers and facilitators to their use among men who have sex with men recruited either online or in voluntary HIV testing centers in Spain. Nearly a third of men (28.7 %) were aware of PrEP and 57.6 % said they would be willing to use it if available, 16.6 % saying they would be unwilling to use PrEP and 25.8 % not being sure. Men who had heard of PrEP were more forceful in their opinions on willingness to use PrEP (willing/not willing: 29.8 %/32.6 % vs. don't know: 21.8 %). The greatest consensus regarding more acceptable PrEP attributes was in the mode of delivery and its cost. Doctors (91 %) or pharmacists (85.3 %) were the preferred providers. The results confirm the need to inform and educate on PrEP and define implementation strategies.

Jaagsiekte Sheep Retrovirus Can Reach Peyer's Patches and Mesenteric Lymph Nodes of Lambs Nursed by Infected Mothers.

Ovine pulmonary adenocarcinoma (OPA) is a contagious lung cancer of sheep caused by jaagsiekte sheep retrovirus (JSRV). It is generally accepted that transmission by the respiratory route occurs under natural conditions. However recent studies strongly indicate that JSRV can also be transmitted to lambs perinatally via colostrum and milk (C/M). The aim of this work was to confirm that C/M can transmit JSRV infection to lambs under natural conditions and investigate the initial events associated with this transmission route. We have analyzed the presence of JSRV in C/M samples from 22 naturally infected, asymptomatic ewes throughout a lactation period, and in various tissues collected from a group of 36 of their lambs that were fed naturally. The lambs were euthanized at 12, 24, 48, and 72 hours and at 5 and 10 days after birth. We detected JSRV-provirus by PCR in the somatic C/M cells from 10/22 ewes (45.45%). The virus was also detected in 9/36 lambs (25%). JSRV-infected cells, with lymphoreticular-like morphology, were observed by immunohistochemistry (IHC) and in situ hybridization (ISH) in Peyer's patches (PP) from the small intestine of the youngest lambs and in mesenteric lymph nodes (MLN) from lambs older than 72 hours. The virus was also detected by PCR in white blood cells (WBC) in 2/36 lambs (5.5%). These results confirm colostral transmission of JSRV to lambs under natural conditions. Infected lymphoreticular cells contained in C/M appear to be involved. These cells can cross the intestinal barrier of newborn lambs, reach the MLN and enter into circulation.

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.

Corticotomies as a surgical procedure to accelerate tooth movement during orthodontic treatment: A systematic review.

BACKGROUND: One of the main aims of orthodontists is to reduce the treatment time as much as possible, particularly in view of the rise in demand for orthodontic treatment among adult patients. The objective of this systematic review was to examine the effectiveness of corticotomy as a surgical procedure that accelerates orthodontic tooth movement, together with its possible adverse effects. MATERIAL AND METHODS: A systematic review of articles in 4 databases, Pubmed, Cochrane, Scopus and Embase, complemented by a manual search, identified 772 articles. The duplicates were eliminated and a critical reading of titles and abstracts led to the rejection of articles that did not meet the objectives of the review, leaving 69. After reading the full text of these articles, 49 were excluded because they did not meet the inclusion criteria. On applying the CONSORT criteria as a quality filter, a further 4 were eliminated due to low quality. Finally, 16 articles (4 systematic reviews and 12 controlled trials) were reviewed. RESULTS: All the studies agree that corticotomy prior to orthodontic treatment accelerates dental movement, reducing the treatment time. With regard to side-effects, no periodontal damage was found, although this was only studied in the short term. CONCLUSIONS: The evidence regarding the results of corticotomy is limited, given the small number of quality clinical studies available. Before this procedure is included as a routine practice in dental surgeries, studies of higher methodological quality are required, studying a greater number of individuals and examining the possible long-term adverse effects and the cost/benefit of the procedure.

Prognostic impact of chondroitin-4-sulfotransferase CHST11 in ovarian cancer.

Ovarian cancer (OvCa) accounts for the highest tumor-related mortality among gynecological malignancies, but the underlying mechanisms are poorly understood. Glycosaminoglycans are abundantly present in ovarian tumors, and there is rising evidence that chondroitin sulfate (CS) as well as diverse carbohydrate sulfotransferases (CHSTs), the enzymes involved in the sulfation process of these structures, plays an important role in metastatic spread of tumor cells. mRNA expression levels of CHST3/7/11/12/13/15 were compared between malignant (86 OvCas) and non-malignant tumors (6 borderline tumors and 3 cystadenomas). CHST11 and CHST15 were further chosen for Western blot analysis in a cohort of 216 OvCas. Protein expression levels were correlated with clinicopathologic prognostic parameters and survival data. A significantly higher mRNA expression of CHST11, CHST12, and CHST15 was measured in ovarian cancer samples in comparison to non-malignant ones, and the same trend was observed for CHST13. For CHST3 and CHST7, no significant differences were found between the two groups. At protein level, high CHST11 expression was independently associated with unfavorable progression-free survival (PFS; p = 0.027). A similar trend was observed for CHST15, showing a nearly significant correlation between high expression levels and shorter recurrence-free survival in patients without macroscopic residual tumor after surgery (p = 0.053). We conclude that CHSTs involved in the synthesis of CS-A and CS-E might influence ovarian cancer progression, and we suggest CHST11 as independent unfavorable prognostic factor in this entity.

Prognostic value of metabolic parameters and clinical impact of ¹8F-fluorocholine PET/CT in biochemical recurrent prostate cancer.

PURPOSE: To evaluate the therapeutic impact of (18)F-fluorocholine (FCH) PET/CT in biochemical recurrent prostate cancer (PC) and to investigate the value of quantitative FCH PET/CT parameters in predicting progression-free survival (PFS). METHODS: This retrospective study included 172 consecutive patients with PC who underwent FCH PET/CT for biochemical recurrence. Mean rising PSA was 10.7 ± 35.0 ng/ml. Patients with positive FCH PET were classified into three groups: those with uptake only in the prostatic bed, those with locoregional disease, and those with distant metastases. Referring physicians were asked to indicate the hypothetical therapeutic strategy with and without the FCH PET/CT results. Clinical variables and PET parameters including SUVmax, SUVpeak, SUVmean, total lesion choline kinase activity (TLCKA) and standardized added metabolic activity (SAM) were recorded and a multivariate analysis was performed to determine the factors independently predicting PFS. RESULTS: In 137 of the 172 patients, the FCH PET/CT scan was positive, and of these, 29.9 % (41/137) had prostatic recurrence, 42.3 % (58/137) had pelvic lymph node recurrence with or without prostatic recurrence, and 27.7 % (38/137) had distant metastases. The FCH PET/CT result led to a change in treatment plan in 43.6 % (75/172) of the 172 patients. Treatment was changed in 49.6 % (68/137) of those with a positive FCH PET/CT scan and in 20 % (7/35) of those with a negative FCH PET/CT scan. After a median follow-up of 29.3 months (95 % CI 18.9 - 45.9 months), according to multivariate analysis age <70 years, SAM ≥23 and SUVmean ≥3 were parameters independently predicting PFS. A nomogram constructed using the three parameters showed 49 months of PFS in patients with the best scores (0 or 1) and only 11 months in patients with a poor score (score 3). CONCLUSION: This study indicates that a positive FCH PET result in PC patients with biochemical recurrence predicts a shorter PFS and confirms the major impact of the FCH PET result on the management of biochemical recurrent PC.

c-FOS suppresses ovarian cancer progression by changing adhesion.

BACKGROUND: C-Fos was initially described as oncogene, but was associated with favourable prognosis in ovarian cancer (OvCa) patients. The molecular and functional aspects underlying this effect are still unknown. METHODS: Using stable transfectants of SKOV3 and OVCAR8 cells, proliferation, migration, invasion and apoptotic potential of c-FOS-overexpressing clones and controls were compared. Adherence to components of the extracellular matrix was analysed in static assays, and adhesion to E-selectin, endothelial and mesothelial cells in dynamic flow assays. The effect of c-FOS in vivo was studied after intraperitoneal injection of SKOV3 clones into SCID mice, and changes in gene expression were determined by microarray analysis. RESULTS: Tumour growth after injection into SCID mice was strongly delayed by c-FOS overexpression, with reduction of lung metastases and circulating tumour cells. In vitro, c-FOS had only weak influence on proliferation and migration, but was strongly pro-apoptotic. Adhesion to components of the extracellular matrix (collagen I, IV) and to E-selectin, endothelial and mesothelial cells was significantly reduced in c-FOS-overexpressing OvCa cells. This corresponds to deregulation of adhesion proteins and glycosylation enzymes in microarray analysis. CONCLUSION: In addition to its known pro-apoptotic effect, c-FOS might influence OvCa progression by changing the adhesion of OvCa cells to peritoneal surfaces.

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).

Superficial necrolytic dermatitis in a dog with an insulin-producing pancreatic islet cell carcinoma.

A 10-year-old dog presented with convulsive crisis and symmetrical hyperkeratotic cutaneous lesions affecting the abdomen, inguinal area, eyelids, muzzles, both pinnae, and all the paw pads. Hypoglycemia and hyperinsulinemia were the main biochemical findings. A mass 2 cm in diameter was detected within the left pancreatic lobe by ultrasonography. It was surgically removed and histologically and immunohistochemically diagnosed as an insulin-producing pancreatic islet cell carcinoma. The animal was eventually euthanized due to lack of clinical improvement. At necropsy, metastatic nodules were observed in the pancreatic lymph nodes and liver. Histopathological findings of cutaneous lesions were highly suggestive of superficial necrolytic dermatitis and were interpreted as a paraneoplastic syndrome derived from the islet cell carcinoma. To the authors' knowledge, this is the first report of superficial necrolytic dermatitis associated with an insulin-producing pancreatic neuroendocrine carcinoma in dogs.

The development, feasibility and acceptability of an Internet-based STI-HIV prevention intervention for young Chilean women.

BACKGROUND: Young Chilean women between 18 and 24 years of age are at high risk of contracting sexually transmitted infection (STI) and human immunodeficiency virus (HIV). The literature shows a shortage of STI-HIV prevention interventions focused on this specific high-risk population and a unique set of barriers to receiving prevention messages. Internet-based interventions are promising for delivering STI-HIV prevention interventions and avoiding barriers to services. AIMS: The study aimed to develop a culturally informed Internet-based STI-HIV prevention intervention for Chilean women between 18 and 24 years of age, to investigate its feasibility and acceptability, and to compile recommendations on what would make the intervention more acceptable and feasible for these women. METHODS: The development of the Internet intervention was facilitated by a process that featured consultation with content and technology experts. A pre-post test design was used to test the acceptability and feasibility of the intervention with 40 young Chilean women between 18 and 24 years of age. RESULTS: The intervention website consisted of four modules of content and activities that support learning. The intervention was feasible and acceptable for young Chilean women between 18 and 24 years of age. DISCUSSION AND CONCLUSION: This study demonstrated the value of engaging multiple expert panels to develop culturally informed and technology-based interventions. The results of this study support the feasibility and acceptability of conducting an Internet-based intervention with multiple sessions, yielding high participation rates in a population in which there are barriers to discussion of STI-HIV prevention and sex-related content. IMPLICATIONS FOR NURSING AND HEALTH POLICY: The outcomes have implications for nursing education and clinical practice and they can be used for the legal and judicial systems to promote or reinforce policies that encourage STI-HIV prevention strategies among women.

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.

Who are the men who have sex with men in Spain that have never been tested for HIV?

OBJECTIVES: The aims of the study were to describe the sociodemographic profile of men who have sex with men (MSM) who have never been tested for HIV and to analyse factors associated with never having been tested. METHODS: The European MSM Internet Survey (EMIS) was implemented in 2010 in 38 European countries on websites for MSM and collected data on sociodemographics, sexual behaviour, and other sexual health variables. A logistic regression analysis was conducted to assess variables associated with never having been tested for HIV. RESULTS: Of the 13,111 respondents living in Spain, 26% had never been tested for HIV. Those who had never been tested were significantly more likely to live in a settlement with fewer than 100,000 inhabitants, be younger than 25 years old, have a lower education level, be a student, and identify themselves as bisexual. In the multivariate analysis, to have never been tested for HIV was associated with being born in Spain [odds ratio (OR) 1.35; 95% confidence interval (CI) 1.192-1.539], living outside large settlements (OR 1.37; 95% CI 1.216-1.534), being younger than 25 years old (OR 2.94; 95% CI 2.510-3.441), being out to no one or only a few people (OR 2.16; 95% CI 1.938-2.399), having had no nonsteady partners in the last 12 months (OR 1.26; 95% CI 1.109-1.422), and being not at all confident to access HIV testing (OR 3.66; 95% CI 2.676-5.003), among others factors. CONCLUSIONS: The profile of the MSM who had never been tested for HIV indicates that most of them were men who were hard to reach (young, bisexual men, in the closet). Interventions should aim to improve access to and the convenience of testing.

Female sex workers and access to social and health services in Catalonia: Influence of region of origin and place of work.

The objectives of the study were to describe the use of social and health services (SHS) of female sex workers (FSW) in Catalonia according to place of work and region of origin, and explore the barriers these women encountered when accessing these services. Quantitative and qualitative methods were combined. A questionnaire-based survey (n = 400) was conducted from October 2009 to January 2010, and complemented by focus group discussions technique (n = 23). More than 60% of FSW had used health services (HS) in the last 6 months (no differences by context of work and region of origin). Nevertheless, there were differences in the characteristics of health resources used. Although all women in clubs contracted the private HS provided by the club itself, they were those who least benefited from social services (SS), in particular Eastern-Europe women (24.6% in the last 6 months). The stigma and discrimination that FSW women suffer were one of the main barriers to access SHS. Women from Eastern Europe who worked in clubs were the most isolated and vulnerable women. Access to the public health system must continue to be provided for all FSW, assuring confidentiality and diminishing the burden associated with discrimination which they generally feel.
