Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND While the efficacy of allergen-specific immunotherapy (ASIT) to treat canine atopic dermatitis has been well established, it remains unclear why not all dogs show the same response to treatment. The goal of the study was to determine the relationship between duration of ASIT and two measurements of success: disease severity and concomitant medication sparing effect. METHODS Data were retrospectively compiled for 145 dogs with atopic dermatitis treated with ASIT. As a measure of treatment compliance, cases were stratified into dogs treated for less than 12 months or for at least 12 months. Treatment efficacy, defined as a reduction in disease severity score (scale 0-10), was compared between both groups, and correlations between treatment success and several related factors were examined. RESULTS ASIT treatment duration was strongly correlated with treatment efficacy. Animals treated for less than 12 months showed lower efficacy rates (22 per cent) than those treated for at least 12 months (65 per cent). Further, in animals treated for at least 12 months, concomitant medications were reduced more (87 per cent) than in animals treated for less than 12 months (39 per cent). CONCLUSION A lack of owner compliance emerged as the main factor explaining the reduced effectiveness of ASIT. To improve treatment adherence, veterinarians and owners need to be better informed about ASIT mechanisms of action before starting treatment.

Abstract
BACKGROUND Different bismuth quadruple therapies containing proton-pump inhibitors, bismuth salts, metronidazole, and a tetracycline have been recommended as third-line Helicobacter pylori eradication treatment after failure with clarithromycin and levofloxacin. AIM To evaluate the efficacy and safety of third-line treatments with bismuth, metronidazole, and either tetracycline or doxycycline. METHODS Sub-study with Spanish data of the "European Registry on H pylori Management" (Hp-EuReg), international multicenter prospective non-interventional Registry of the routine clinical practice of gastroenterologists. After previous failure with clarithromycin- and levofloxacin-containing therapies, patients receiving a third-line regimen with 10/14-day bismuth salts, metronidazole, and either tetracycline (BQT-Tet) or doxycycline (BQT-Dox), or single capsule (BQT-three-in-one) were included. Data were registered at AEG-REDCap database. Univariate and multivariate analyses were performed. RESULTS Four-hundred and fifty-four patients have been treated so far: 85 with BQT-Tet, 94 with BQT-Dox, and 275 with BQT-three-in-one. Average age was 53 years, 68% were women. Overall modified intention-to-treat and per-protocol eradication rates were 81% (BQT-Dox: 65%, BQT-Tet: 76%, BQT-three-in-one: 88%) and 82% (BQT-Dox: 66%, BQT-Tet: 77%, BQT-three-in-one: 88%), respectively. By logistic regression, higher eradication rates were associated with compliance (OR = 2.96; 95% CI = 1.01-8.84) and no prior metronidazole use (OR = 1.96; 95% CI = 1.15-3.33); BQT-three-in-one was superior to BQT-Dox (OR = 4.46; 95% CI = 2.51-8.27), and BQT-Tet was marginally superior to BQT-Dox (OR = 1.67; 95% CI = 0.85-3.29). CONCLUSION Third-line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10-day BQT-three-in-one or 14-day BQT-Tet. Doxycycline seems to be less effective and therefore should not be recommended.

Abstract
Dogs are the main reservoir of Leishmania infantum and in some countries have been regularly culled as part of government policy to control visceral leishmaniasis. At the 13th Symposium of the Companion Vector-Borne Diseases World Forum in Windsor, UK, March 19–22, 2018, we consolidated a consensus statement regarding the usefulness of dog culling as a means of controlling visceral leishmaniasis. The statement highlighted the futility of culling infected dogs, whether healthy or sick, as a measure to control the domestic reservoir of L. infantum and reduce the risk for visceral leishmaniasis.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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).

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
AIM The aim of this study was to compare different dosimetric approaches on therapy naïve patients enrolled in a multicentre fractionated radioimmunotherapy trial, to determine which methodological approach correlates with bone marrow toxicity. METHODS Twenty-height non-Hodgkin lymphoma patients were treated with one or two fractions of 90Y-Ibritumomab-Tiuxetan (11.1 MBq/kg) 8 to 12 weeks apart in four different institutions. Quantitative imaging with 111In-Ibritumomab-Tiuxetan (185 MBq) was performed at 0, 1, 4 and 7 days after infusion, starting two weeks before the therapeutic administration. A whole-body (WB) CT scan was also acquired prior to the 111In-Ibritumomab injection, for attenuation correction purposes and was segmented to derive patient-specific organ masses. All dosimetry processing was centralized in a single institution. The first method (M_2D) was based on geometric mean WB scans, corrected for attenuation, scatter and organs superposition. The second method (M_2.5D) was based on the computed assisted matrix inversion approach and used segmented CT scans. The third method (M_3D) used iterative reconstruction of tomographic scans, corrected for attenuation, scatter and collimator response. Absorbed doses were estimated for lungs, liver, kidneys and spleen using MIRD S values adjusted for organ masses. Bone marrow (BM) absorbed doses were evaluated according to imaging methods (3) and compared to blood-based approaches. RESULTS For some patients, organ masses such as liver or spleen significantly differed from male/female reference masses, whereas lungs and kidneys masses were relatively constant. Except for lungs, absorbed doses estimated by M_2D were higher than those from M_2.5D and these, in turn, were higher that those calculated from M_3D (Wilcoxon P<8.6e-4). Median organ absorbed dose estimates were equivalent for both fractions except for the spleen. In fact, spleen absorbed doses for the second fraction were lower than those for the first fraction, regardless of the approach. Possible explanations are that patient spleen masses were kept constant for analysis of both fractions and/or that spleen uptake was lowered after the first fraction. Estimation of BM absorbed doses from blood sampling was unable to predict platelet toxicity, but image-based methods performed better. Additionally, for most organs, the absorbed dose delivered by the first fraction could predict that delivered by the second fraction. CONCLUSION These results confirm that different acquisition/processing protocols will lead to statistically different absorbed doses. Additionally, image-based dosimetric approaches are needed in order to correlate absorbed dose to bone marrow toxicity.

Abstract
A multisyringe flow-injection approach has been coupled to hydride generation-atomic fluorescence spectrometry (HG-AFS) with UV photo-oxidation for dimethylarsinic (DMA), inorganic As and total As determination, depending on the pre-treatment given to the sample (extraction or digestion). The implementation of a UV lamp allows on-line photo-oxidation of DMA and the following arsenic detection, whereas a bypass leads the flow directly to the HG-AFS system, performing inorganic arsenic determination. DMA concentration is calculated by the difference of total inorganic arsenic and measurement of the photo-oxidation step. The detection limits for DMA and inorganic arsenic were 0.09 and 0.47 μg L(-1), respectively. The repeatability values accomplished were of 2.4 and 1.8%, whereas the injection frequencies were 24 and 28 injections per hour for DMA and inorganic arsenic, respectively. This method was validated by means of a solid reference material BCR-627 (muscle of tuna) with good agreement with the certified values. Satisfactory results for DMA and inorganic arsenic determination were obtained in several water matrices. The proposed method offers several advantages, such as increasing the sampling frequency, low detection limits and decreasing reagents and sample consumption, which leads to lower waste generation.

Abstract
INTRODUCTION Hispanic women aged 50 and over (OHW) are a minority in the U.S. at high risk of acquiring HIV and the least studied group of population in relation to health, social characteristics and sexual behavior. OBJECTIVE To investigate the factors that increase HIV risk among OHW with the purpose of developing or adapting an intervention appropriate for their "age and culture". METHODOLOGY A cross-sectional descriptive study with a sample of 50 OHW, sexually active and who residing in Miami, Florida, U.S. A structured questionnaire was administered by trained bilingual interviewers (English/Spanish). Participants were recruited from different locations in South Florida. Data were analyzed using descriptive statistics, including central tendency and dispersion measures. RESULTS OHW's mean age was 55.7 ± 6 years old (range 50-76 years old). All the OHW were in the menopause. HIV PREVENTION OHW reported average levels of HIV knowledge and partner communication. In the sample OHW reported depression symptoms, intimate partner violence, negative attitudes towards people living with HIV and low perceived risk of acquiring HIV. OHW mentioned learning needs in topics related to HIV prevention and age changes. CONCLUSION OHW are at risk of acquiring HIV and they have special needs in terms of HIV prevention.

Abstract
This report describes the clinical and histopathological characteristics of a squamous cell carcinoma infiltrating the cervix and the vaginal wall, producing reproductive symptoms and subnormal fertility in an adult ewe. Necropsy showed a large (15-cm-long) neoplastic mass infiltrating the vaginal wall and the cervix. Histopathological examination revealed atypical squamous epithelial cords invading the basal membrane and dermis, round anaplastic cells, focal areas of necrosis, keratinisation of isolated cells, and pronounced infiltration by mononuclear cells around the cords. No squamous cell carcinoma of such localisation has been reported from sheep before. In humans, this tumour is the most common gynaecological malignancy in the world.
