RESUMO
Introduction: Sexuality is an integral part of development and personality, and is important in healthcare. Nurses are among the most representative healthcare professionals. For holistic and inclusive nursing care practice and to improve equality, human rights, well-being, and health of individuals, the curricula of nursing courses must integrate broad knowledge about sexuality and its diversity. This study aimed to identify and analyze nursing students' knowledge of sexuality, sex, and gender diversity. The present study was part of a multicenter study conducted in Europe. Methods: Questionnaires were administered in three nursing schools to assess nursing students' knowledge (n = 75). Data processing was performed using Excel® software version 20 and IRaMuTeQ (R Interface pour les Analysis Multidimensionnelles de Textes et de Questionnaires) 0.7 alpha 2, allowing organization by category and subsequent thematic analysis using content analysis. Results: The textual corpus "Nursing students' knowledge about sexuality in its diversity," was divided into two sub-corpus: "Students' perception of sexuality" and "Students' perception of gender identity," originating Class 6 "Eroticism" (14.23%) and Classes 4 "Sexual Orientation" (16.07%) and 3 "Heteronormative" (16.07%), the latter with greater proximity to each other and consequently to Class 6. Similarly, Classes 1 "Gender" (20.36%) and 5 "Cisgender" (12.14%) also presented a greater interrelationship between themselves and consecutively with Class 2 "Gender Identity" (15.36%). Discussion: The analyses revealed that though nursing students possessed knowledge about sexuality and its diversity, this knowledge was elementary and did not reveal a sustained appropriation of concepts related to sexuality, sexual orientation, and gender diversity. For some questions, the absence of students' answers were noteworthy, and may be associated with their personal reservation in expressing themselves on this sensitive and intimate theme. To ensure diversity, inclusivity, and impartiality in nursing practice, it is imperative to change the curriculum plans of nursing courses to address the theme of sexuality during the training process of nurses in Europe.
RESUMO
The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI) and western blots (WB) were performed to detect Borrelia burgdorferi (sensu lato); a tamponated acidified antigen test (AAT) and 2-mercaptoethanol (2-ME) were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT) was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96%) were reactive for Lyme borreliosis, three (1.4%) for brucellosis, 25 (12.1%) for leptospirosis and 143 (69.1%) for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH) that was considered to be average (0.733) in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.
RESUMO
Nurse educators are tasked with the education of students to become providers of holistic care, and part of that care includes sexuality. Students carry attitudes and beliefs that influence their behavior; therefore, students who carry negative attitudes about sexual healthcare are less likely to provide that care. This is an international, multicenter study of nursing students' attitudes and beliefs about the provision of sexual healthcare. The Sexuality Attitudes and Beliefs Survey, which measures attitudes toward the provision of sexual healthcare and has a range of scores from 12 to 72, was given to 129 students across Spain, Portugal, Italy and the United States and revealed negative attitudes about sexuality, with a mean SABS score of 39.95. Higher scores on the SABS reveal more negative attitudes and reduced likelihood of provision of sexual healthcare. Statistically significant differences were found when comparing queer and heterosexual students (41.69 vs. 38.06), and students in their final year of school held more negative attitudes toward the provision of sexual healthcare (41.4 vs. 39.5 and 39.2). This study shows that nurse educators continue to need to focus on the attitudes student nurses carry about sexuality. There is a critical shortage of education strategies to meet the needs of student nurses so that they will be comfortable and confident in providing sexual healthcare.
RESUMO
The laborious microscopic agglutination test (MAT) is the gold standard serologic test for laboratory diagnosis of leptospirosis. We developed EIA based serologic assays using recombinant proteins (rLigA, rLigB, rLipL32) and whole-cell extracts from eight Leptospira serovars as antigen and assessed the diagnostic performance of the new assay within each class, against MAT positive (MAT+) human sera panels from Portugal/PT (n = 143) and Angola/AO (n = 100). We found that a combination of recombinant proteins rLigA, rLigB and rLipL32 correctly identified antigen-specific IgG from patients with clinical and laboratory confirmed leptospirosis (MAT+) with 92% sensitivity and ~ 97% specificity (AUC 0.974) in serum from the provinces of Luanda (LDA) and Huambo (HBO) in Angola. A combination of whole cell extracts of L. interrogans sv Copenhageni (LiC), L. kirschneri Mozdok (LkM), L. borgpetersenii Arborea (LbA) and L. biflexa Patoc (LbP) accurately identified patients with clinical and laboratory confirmed leptospirosis (MAT+) with 100% sensitivity and ~ 98% specificity for all provinces of Angola and Portugal (AUC: 0.997 for AO/LDA/HBO, 1.000 for AO/HLA, 0.999 for PT/AZ and 1.000 for PT/LIS). Interestingly, we found that MAT+ IgG+ serum from Angola had a significantly higher presence of IgD and that IgG3/IgG1 isotypes were significantly increased in the MAT+ IgG+ serum from Portugal. Given that IgM/IgD class and IgG3/IgG1 specific isotypes are produced in the earliest course of infection, immunoglobulin G isotyping may be used to inform diagnosis of acute leptospirosis. The speed, ease of use and accuracy of EIA tests make them excellent alternatives to the laborious and expensive MAT for screening acute infection in areas where circulating serovars of pathogenic Leptospira are well defined.

Leptospires are spirochetes of Leptospira genus. Infection in humans occurs by penetration into the mucous membranes, or into the skin (small wounds or abrasions). Humans are infected when they contact with urine of rodents, the main reservoirs. We aimed to evaluate the presence of anti-Leptospira spp antibodies and leptospiral DNA in sanitation workers (occupational group with increased risk) from Lisbon and Tagus Valley Region (Portugal). Blood samples were collected from 347 sanitation workers, being applied a questionnaire to analyze exposure to rodents and preventive measures. The samples were screened by MACROLepto-test, for the presence of antibodies against pathogenic leptospires. "Positive" and "Non conclusive" samples were then tested with Microscopic Agglutination Test (MAT). Two nested-PCR protocols (primers LeptoA-LeptoB and lipL32) were applied for Leptospira spp DNA detection. It was not observed anti-Leptospira spp antibodies in the worker's samples. However, it was detected non-pathogenic leptospires in a serum sample. Furthermore, 77% had previously seen rodents in the workplace and 94% always used Personal Protective Equipment (PPE). Despite the regular presence of rodents in their workplace, the use of PPE and hygiene measures seemed to be able to prevent the workers contact with this infectious agent.

Nowadays, at least four clinically important B. burgdorferi sensu lato (s.l.) genospecies (B. afzelii, B. garinii, B. burgdorferi sensu stricto (s.s.) and B. lusitaniae) circulate in Portugal. Each genospecies has a different tropism that resuls in a diverse array of clinical manifestations. The standard diagnostic procedure used is normally simple, nevertheless, during the "window-period" phase, in which specific antibodies cannot yet be detected, diagnosis becomes difficult, and calls for reliable, sensitive and specific laboratory methods, such as molecular tests. The aim of this study was to develop and evaluate a multiplex TaqMan real-time PCR assay to infer the presence of B. burgdorferi s.l. genospecies in clinical and vector-derived samples. The assay consists of two steps: (i) a first duplex real-time PCR targeting both flaB of B. burgdorferi s.l., and an internal control (18S rDNA for tick samples or the mammal ß-actin gene for clinical samples); and (ii) a second tetraplex real-time PCR targeting the flaB gene of B. afzelii, B. garinii, B. burgdorferi s.s. and B. lusitaniae. The first step revealed a high specificity and sensitivity, allowing the detection of as low as 20 genome equivalents (GE) of B. burgdorferi s.l. from isolated cultures, clinical samples and ticks. The second step revealed high specificity, but a slightly lower sensitivity (2×102 GE) for detection of B. afzelii, B. garinii, B. burgdorferi s.s. and B. lusitaniae in purified DNA extracts, and particularly when testing cerebrospinal fluid (CSF) samples. Nonetheless, both real-time PCR protocols were developed to be applied at the beginning of the infection, to improve early diagnosis of Lyme borreliosis (LB), where detection of Borrelia should not rely on the use of CSF samples. The assay here described is of special interest for the analysis of both environmental and clinical samples, being advantageous in the former phase screening of Lyme borreliosis, when the efficiency of serologically based diagnoses may be seriously compromised.

Currently, direct detection of Leptospira can be done in clinical laboratories by conventional and by real-time PCR (qRT-PCR). We tested a biobank of paired samples of serum and urine from the same patient (202 patients) presenting at the hospital in an area endemic for leptospirosis using qRT-PCR followed by high resolution melting (HRM) analysis. The results were compared with those obtained by conventional nested PCR and with the serologic gold standard microscopic agglutination test (MAT). Differences were resolved by sequencing. qRT-PCR-HRM was positive for 46 of the 202 patients (22.7%, accuracy 100%) which is consistent with known prevalence of leptospirosis in the Azores. MAT results were positive for 3 of the 46 patients (6.5%). Analysis of paired samples allowed us to identify the illness point at which patients presented at the hospital: onset, dissemination or excretion. The melting curve analysis of Leptospira species revealed that 60.9% (28/46) of patients were infected with L. interrogans and 39.1% (18/46) were infected with L. borgpetersenii, both endemic to the Azores. We validated the use of qRT-PCR-HRM for diagnosis of leptospirosis and for identification of the Leptospira species at the earliest onset of infection in a clinical setting, in less than 2 hours.

Rodents play an important role in the transmission of pathogenic Leptospira spp. However, in Angola, neither the natural reservoirs of these spirochetes nor leptospirosis diagnosis has been considered. Regarding this gap, we captured rodents in Luanda and Huambo provinces to identify circulating Leptospira spp. Rodent kidney tissue was cultured and DNA amplified and sequenced. Culture isolates were evaluated for pathogenic status and typing with rabbit antisera; polymerase chain reaction (PCR) and sequencing were also performed. A total of 37 rodents were captured: Rattus rattus (15, 40.5%), Rattus norvegicus (9, 24.3%), and Mus musculus (13, 35.2%). Leptospiral DNA was amplified in eight (21.6%) kidney samples. From the cultures, we obtained four (10.8%) Leptospira isolates belonging to the Icterohaemorrhagiae and Ballum serogroups of Leptospira interrogans and Leptospira borgpetersenii genospecies, respectively. This study provides information about circulating leptospires spread by rats and mice in Angola.

Borrelia miyamotoi, a relapsing fever spirochete, has been found recently in Ixodes ricinus ticks; however, little is known about its spatial distribution and potential local impact on human health. A total of 640 ticks (447 nymphs and 193 adults) collected throughout Portugal were analyzed using two nested PCR protocols, one targeting the flagellin gene and the other the internal transcribed space region between the 5S and the 23S rRNA. As a result, B. miyamotoi was detected, for the first time, in one guesting I. ricinus nymph collected in the Lisboa district. In addition, a prevalence of 11% (71/640) for B. burgdorferi sensu lato was obtained. Even though no human relapsing fever cases due to infection by B. miyamotoi have been reported yet in Portugal, surveillance must be improved to provide better insight into the prevalence and distribution of this spirochete in ticks.

Lyme borreliosis is the most common tick-borne zoonosis in the northern hemisphere. Several vertebrates are crucial in the epidemiological cycle of Borrelia burgdorferi sensu lato, but the role of wild boar as a reservoir is still unknown. Sera were collected from 90 wild boars shot in the Trás-os-Montes region, Northern Portugal (hunting season 2011/2012). In this study, Borrelia DNA was detected for the first time by nested-PCR in three different sera, suggesting that the wild boar may be a potential reservoir for this spirochete. Sequencing results show 100% similarity with Borrelia afzelii. Further studies are needed to evaluate the public health risks associated with boar hunting.

The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of spirochete DNA infecting ticks that parasitize horses used for animal traction, in the rural municipality mentioned. In conclusion, this study opens up promising prospects for determining the infection rate of B. burgdorferi s.s. genospecies or other species in the equine population, as well as the impact of the infection rate on Lyme disease in the state of Parana.

OBJECTIVES: The aim of this study was the first identification of Leptospira isolates from Azorean inpatients. METHODS: Whole blood samples from 68 inpatients attending the São Miguel Hospital between 2006 and 2008, with a clinical and epidemiological suspicion of leptospirosis, were inoculated in a transport medium broth at the patient's bedside and further processed using a serial dilution technique prior to culture. At admission, 62 (91%) patients were also analyzed for the presence of leptospiral DNA by a nested PCR and 40 (59%) for specific agglutinins by microscopic agglutination test (MAT). The isolates obtained were first assigned at the serogroup level by both MAT reactivity with hyperimmune rabbit antisera and a PCR-based assay with the single primer iRep1. The species identification was performed by DNA sequencing. The use of monoclonal antibodies allowed intraspecific discrimination at the serovar level. RESULTS: Of the 10 (14.7%) human Leptospira isolates, seven were identified as Leptospira interrogans serovar Copenhageni and three as Leptospira borgpetersenii serovar Arborea, which is in agreement with previous data from the Azorean rodent population. CONCLUSIONS: This study represents a great step towards the definitive identification of the pathogenic leptospires in Azorean patients and confirms the bacteriological human-rodent connection for the first time.

A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI) and western blots (WB) were performed to detect Borrelia burgdorferi (sensu lato); a tamponated acidified antigen test (AAT) and 2-mercaptoethanol (2-ME) were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT) was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96%) were reactive for Lyme borreliosis, three (1.4%) for brucellosis, 25 (12.1%) for leptospirosis and 143 (69.1%) for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH) that was considered to be average (0.733) in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.
