Este estudo teve como objetivos avaliar a Qualidade de Vida (QV), sintomas depressivos, estresse, satisfação sexual e vivências emocionais em pacientes que apresentam infertilidade. Participaram deste estudo 500 pessoas (mulheres e homens), com idade igual ou maior a 18 anos, pacientes de um ambulatório de reprodução humana localizado no Grande ABC Paulista. O estudo utilizou instrumentos de avaliação autoaplicáveis: WHOQOL-Bref, BDI-II, ISQ, ICQ, ISS e questionário sócio-demográfico. A caracterização da amostra estudada demostrou alto nível escolar (62,4pc), boa condição econômica (80,2pc, idade superior a 30 anos (82,8pc) e a maioria apresenta infertilidade primária (73,2pc). Quanto à QV, níveis de depressão e estresse os homens apresentam melhores resultados quando comparados às mulheres. No que ser refere aos níveis de satisfação sexual 56,6% dos participantes descrevem ter satisfação sexual, mas 45,4% afirmam ter insatisfação sexual e não houve diferença entre os gêneros. As análises dos dados mostraram que é maior o número de mulheres do que o de homens que procuram atendimento para infertilidade (64,8pc). Pôde-se comprovar que além das dificuldades provenientes da infertilidade, o tratamento, também, impacta sobre a vida dessas pessoas. Foram diversos participantes que descreveram significativas mudanças (42,8pc), dos quais apontaram em maioria absoluta (92,6pc) uma piora no estado de humor devido ao tratamento. Como também é alto o índice de pessoas que descrevem sintomas de depressão (38,8pc) e estresse (31,4pc) acima da média da população geral. Ao considerar as especificidades da qualidade de vida averiguou-se um maior impacto no domínio psicológico dos pacientes (15,20 pontos) comparado ao físico (15,68 pontos). Estes resultados ressaltam a importância do atendimento psicológico para as pessoas em programas de reprodução humana.

Três grupos constituídos por indivíduos de tilápia da espécie Oreochromis mossambicus foram observados por um período de 6 meses e registado os seus comportamentos reprodutivos, número de fêmeas em incubação e o número de fry que nasceram durante este tempo. Cada grupo apresentava proporções sexuais distintas (macho:fêmea), nomeadamente, 1:3, 1:4 e 2:2. Após a evolução do estágio das fry a alevins, foram testados nestes indivíduos 3 dietas experimentais: a dieta RT (ração para tilápia), a dieta RD (dieta para douradas) e a Mix (uma mistura de 50% de cada uma das rações anteriormente referidas). Os alevins foram distribuídos em 9 tanques, 20 indivíduos/tanque, existindo três réplicas por dieta e todos se encontravam a uma temperatura de 28 ± 1ºC. Foram alimentados 3 vezes por dia durante 11 semanas, fazendo jejum 1 dia por semana. A cada 2 semanas, os indivíduos eram pesados e medidos e a quantidade de ração era ajustada de acordo com o seu crescimento. Como forma de se reduzir o stress neste procedimento de medição e pesagem, utilizaram-se três anestésicos a diferentes concentrações: MS-222 (0,15, 0,25 e 0,35ml L-1), óleo de cravo (0,10, 0,15 e 1,2ml L-1) e 2-fenoxietanol (0,40, 0,60, 0,80 e 1,00ml L-1). Registaram-se os tempos de indução e recuperação e avaliou-se qual o anestésico mais eficaz. No final do ensaio, os indivíduos foram mortos por choque térmico, filetados e sujeitados a estudos para avaliação do teor de proteína, lípidos, humidade e cinzas. No final de todo este trabalho experimental verificou-se que existiu reprodução nos Grupos 1 e 2 durante os 6 meses e que a melhor proporção sexual é 1:3 (macho:fêmea). Observou-se que as fêmeas que produzem mais posturas seguidas têm um menor número de fry por postura e as que fazem um maior intervalo de tempo entre cada postura, produzem posturas com um maior número de fry. Para qualquer uma destas opções das fêmeas, a taxa de mortalidade das fry é muito reduzida. No ensaio das dietas, os alevins aceitaram com boa aceitabilidade as três dietas mas com o decorrer do tempo, os indivíduos da dieta RD começaram a ganhar hemorragias em algumas partes do corpo. Não existiram diferenças significativas entre as dietas. A dieta Mix foi a que mostrou melhores resultados finais com um peso e comprimento máximos de 4,51 ± 3,39g e 3,36 ± 1,81cm, respetivamente. Para os valores de WG, SGR e FCR também não existiram diferenças significativas para as três iv dietas, sendo a dieta Mix a obter os valores máximos para WG (4,71g) e SGR (2,97% dia-1) mas com o FCR baixo (12,45 g/g). Para os resultados da composição química obtiveram-se diferenças estatisticamente significativas (P < 0,05) nos dados da proteína e humidade. A dieta RT foi a que apresentou um maior teor de proteína (18,53%) e os valores máximos para a humidade foram nas dietas RT (80.54%) e Mix (80,57%). Os lípidos e as cinzas não tiveram diferenças significativas e os valores máximos para estes dois parâmetros foram 1,38% e 1,50% na RT, respetivamente. Para os anestésicos estudados existiram diferenças significativas (P < 0,05) para os tempos de anestesia e recuperação pertencentes ao MS-222 e 2-fenoxietanol; o óleo de cravo apenas apresentou diferenças significativas no tempo de indução. As concentrações que mais eficazes se mostraram para anestesiar Tilápias Moçambicanas foram: 0,25ml L-1 para o MS-222, 0,10ml L-1 para o óleo de cravo e 0,80ml L-1 e 1,00ml L-1 para o 2-fenoxietanol. Os resultados deste trabalho sugerem que a reprodução de Tilápia Moçambicana se consegue com bastante sucesso quando se proporcionam condições ótimas, principalmente, a temperatura que é um dos fatores mais importantes; é uma espécie que aceita com facilidade variados tipos de rações; e os anestésicos utilizados mostraram-se eficazes a anestesiar os juvenis desta espécie apesar de ser necessário continuar o estudo com mais concentrações.

To detect the presence of male DNA in vaginal samples collected from survivors of sexual violence and stored on filter paper. A pilot study was conducted to evaluate 10 vaginal samples spotted on sterile filter paper: 6 collected at random in April 2009 and 4 in October 2010. Time between sexual assault and sample collection was 4-48hours. After drying at room temperature, the samples were placed in a sterile envelope and stored for 2-3years until processing. DNA extraction was confirmed by polymerase chain reaction for human β-globin, and the presence of prostate-specific antigen (PSA) was quantified. The presence of the Y chromosome was detected using primers for sequences in the TSPY (Y7/Y8 and DYS14) and SRY genes. β-Globin was detected in all 10 samples, while 2 samples were positive for PSA. Half of the samples amplified the Y7/Y8 and DYS14 sequences of the TSPY gene and 30% amplified the SRY gene sequence of the Y chromosome. Four male samples and 1 female sample served as controls. Filter-paper spots stored for periods of up to 3years proved adequate for preserving genetic material from vaginal samples collected following sexual violence.

Sexual dysfunction (SD) affects up to 80% of multiple sclerosis (MS) patients and pelvic floor muscles (PFMs) play an important role in the sexual function of these patients. The objective of this paper is to evaluate the impact of a rehabilitation program to treat lower urinary tract symptoms on SD of women with MS. Thirty MS women were randomly allocated to one of three groups: pelvic floor muscle training (PFMT) with electromyographic (EMG) biofeedback and sham neuromuscular electrostimulation (NMES) (Group I), PFMT with EMG biofeedback and intravaginal NMES (Group II), and PFMT with EMG biofeedback and transcutaneous tibial nerve stimulation (TTNS) (Group III). Assessments, before and after the treatment, included: PFM function, PFM tone, flexibility of the vaginal opening and ability to relax the PFMs, and the Female Sexual Function Index (FSFI) questionnaire. After treatment, all groups showed improvements in all domains of the PERFECT scheme. PFM tone and flexibility of the vaginal opening was lower after the intervention only for Group II. All groups improved in arousal, lubrication, satisfaction and total score domains of the FSFI questionnaire. This study indicates that PFMT alone or in combination with intravaginal NMES or TTNS contributes to the improvement of SD.

To assess sexual function (SF) and quality of life (QOL) in women with polycystic ovary syndrome (PCOS). A cross-sectional study was conducted to assess 56 women with PCOS and 102 control women with regular menstrual cycles. To assess SF and QOL in Brazilian women with PCOS with Female Sexual Function Index (FSFI) and the WHOQOL-bref questionnaires. Women with PCOS had a worse evaluation to arousal, lubrication, satisfaction, pain and total FSFI, and there was no difference in sexual desire and orgasm. Besides, they had a worse evaluation concerning health status than controls. The body mass index was inversely correlated to the QOL, especially to the physical, psychological, environment aspects and self-assessment of QOL, but it did not show correlation to the SF. Women with PCOS had a worse sexual function and self-assessment of health condition in comparison to controls. The body weight as isolated symptom was correlated to the worsening in quality of life, but not with the worsening of sexual function.

Women with premature ovarian failure (POF) often manifest complaints involving different aspects of sexual function (SF), regardless of using hormone therapy. SF involves a complex interaction between physical, psychological, and sociocultural aspects. There are doubts about the impact of different complaints on the global context of SF of women with POF. To evaluate the percentage of influence of each of the sexuality domains on the SF in women with POF. Cross-sectional study with 80 women with POF, matched by age to 80 women with normal gonadal function. We evaluated SF through the Female Sexual Function Index (FSFI), a comparison between the POF and control groups using the Mann-Whitney test. Component exploratory factor analysis was used to assess the proportional influence of each domain on the composition of the overall SF for women in the POF group. SF was evaluated using FSFI. Exploratory Factor Analysis for components was used to evaluate the role of each domain on the SF of women with POF. The FSFI score was significantly worse for women with POF, with a decrease in arousal, lubrication, orgasm, satisfaction, and dyspareunia. Exploratory factor analysis of SF showed that the domain with greater influence in the SF was arousal, followed by desire, together accounting for 41% of the FSFI. The domains with less influence were dyspareunia and lubrication, which together accounted for 25% of the FSFI. Women with POF have impaired SF, determined mainly by changes in arousal and desire. Aspects related to lubrication and dyspareunia complaints have lower determination coefficient in SF. These results are important in adapting the approach of sexual disorders in this group of women.

Studies have associated the metabolic syndrome with poor sexual function; the results, however, are controversial. To evaluate the relationship between the metabolic syndrome and sexual function and to identify the factors associated with poor sexual function. A secondary analysis of a cross-sectional cohort study including 256 women of 40-60 years of age receiving care at the outpatient department of a university teaching hospital. A specific questionnaire was applied to collect sociodemographic and behavioral data, and the Short Personal Experience Questionnaire was used to evaluate sexual function, with a score ≤ 7 being indicative of poor sexual function. Anthropometric measurements, blood pressure, fasting glucose, high-density lipoprotein, total cholesterol, triglycerides, follicle-stimulating hormone and thyroid stimulating hormone levels were determined. The prevalence of the metabolic syndrome, as defined by the International Diabetes Federation, was 62.1%, and the prevalence of poor sexual function was 31.4%. The only factor related to female sexual function that was associated with the metabolic syndrome was sexual dysfunction in the woman's partner. The factors associated with poor sexual function in the bivariate analysis were age >50 years (P=0.003), not having a partner (P<0.001), being postmenopausal (P=0.046), the presence of hot flashes (P=0.02), poor self-perception of health (P=0.04), partner's age ≥ 50 years, and time with partner ≥ 21 years. Reported active (P=0.02) and passive (P=0.01) oral sex was associated with an absence of sexual dysfunction. In the multiple regression analysis, the only factor associated with poor sexual function was being 50 years of age or more. The prevalence of the metabolic syndrome was high and was not associated with poor sexual function in this sample of menopausal women. The only factor associated with poor sexual function was being over 50 years of age.

In order to evaluate the psychological variables that affect sexual dysfunction (SD) in epilepsy, where compared 60 epileptics (Group 1) with 60 healthy individuals (Group 2), through the State-Trait Anxiety Inventory (Spielberger et al., 1970), Beck Depression Inventory (Beck, 1974) and Sexual Behavior Interview (Souza, 1995). Sexual dysfunction (SD), anxiety and depression were found more frequently in Group 1 than in Group 2 and were not related to sex. Variables such as the onset duration and frequency of seizures as well as the use to medication were not associated with SD. Temporal lobe epilepsy was related to SD (p = 0.035) but not to anxiety or depression. Anxiety and depression were related to SD in both groups. Perception in controlling the seizures was closely related to anxiety (p = 0) and depression (p = 0.009). We conclude that psychological factors play an important role in the alteration of sexual behavior in epileptics and that suitable attention must be given to the control of these variables.

Characteriza of the inclusion complex ropivacaine: beta-cyclodextrin. Ropivacaine (RVC) is a widely used local anesthetic. The complexation of RVC with beta-cyclodextrin (beta-CD) is of great interest for the development of more efficient local anesthetic formulations. The present work focuses on the characterization of the RVC:beta-CD complex by nuclear magnetic resonance (NMR). The stoichiometry of the complex is 1:2 RVC:beta-CD. DOSY-NMR shows that the association constant is 55.5 M-1. Longitudinal relaxation time results show that RVC changes its mobility in the presence of beta-CD. This study is focused on the physicochemical characterization of inclusion complexes that are potentials options for pain treatment.
