Modified pubovaginal sling technique in the surgical management of female stress urinary incontinence

Objective: To assess the application of aponeurotic sling by a modified technique with direct visualization of needles in patients with stress urinary incontinence. Methods: we applied the Kings Health Questionnaire (KHQ) for quality of life, gynecological examination, urinalysis I and urine culture approximately seven days prior to the urodynamic study (UDS) and the one-hour PAD test in patients undergoing making aponeurotic sling with its passing through the retropubic route with direct visualization of the needle, PAD test and King's Helth Questionnaire before and after surgery. Results: The mean age was 50.6 years, BMI of 28 and Leak Pressure (LP) 58,5cm H2O; 89% were Caucasian. Forty-six of them were monitored for three and six months, 43 for 12 months. The objective cure rate at 12 months postoperatively was approximately 93.5%. In evaluating quality of life, we observed a significant improvement in 12 months postoperatively compared with the preoperative period. There was no no urethral/bladder injury. As adverse results, we had one persistent urinary retention (2.3%), who was submitted to urethrolysis, currently without incontinence. Conclusion: The proposed procedure is safe as for the risk of bladder or urethral injuries, promoting significant improvement in quality of life and objective cure.

Tradução para português, adaptação cultural e validação do Female Sexual Function Index

OBJETIVO: traduzir para o português, adaptar culturalmente e validar o questionário Female Sexual Function Index (FSFI). MÉTODOS: dois tradutores brasileiros, cientes dos objetivos desta pesquisa, preparam duas versões do FSFI para o português, as quais foram retro-traduzidas por outros dois tradutores ingleses. As diferenças foram harmonizadas e pré-testadas em um estudo piloto. As versões finais do FSFI e de outro questionário, o Short-Form Health Survey, já vertido e publicado em português, foram simultaneamente administradas a cem pacientes. Foram testadas as propriedades psicométricas do FSFI, como confiabilidade (consistência interna e teste-reteste) e validades de construto. O reteste foi realizado após quatro semanas, a partir da primeira entrevista. RESULTADOS: o processo de adaptação cultural não alterou a versão em português do FSFI comparado ao original. O alfa de Cronbach padronizado do questionário foi 0,96; avaliado por domínios, variou de 0,31 a 0,97. Como medida de confiabilidade teste-reteste, foi aplicado o coeficiente de correlação intra-classes, que foi considerado forte e idêntico (1,0). O coeficiente de correlação de Pearson entre o FSFI e o Short-Form Health Survey foi positivo, mas fraco na maioria dos domínios afins, variando de 0,017 a 0,036. CONCLUSÕES: a versão do FSFI foi traduzida para o português e adaptada culturalmente e é válida para avaliação da resposta sexual das mulheres brasileiras.

Validade e confiabilidade de uma versão on-line do Female Sexual Function Index por teste e reteste

OBJETIVO: Foi testar a validade e a confiabilidade de uma versão on-line do Female Sexual Function Index (FSFI). MÉTODOS: Uma versão on-line do FSFI foi comparada à versão tradicional, em papel. Para tanto, estudantes de Fisioterapia de três cidades foram alocadas randomicamente em dois grupos - G-pp/ol (n=126) e G-ol/pp (n=147). As mulheres do G-pp/ol responderam ao FSFI do modo tradicional, em papel e caneta, enquanto o G-ol/pp respondeu a uma versão on-line do mesmo questionário. Após 15 dias de intervalo, houve nova coleta, quando o G-pp/ol respondeu a versão on-line enquanto o G-ol/pp respondeu no papel. Todos os dados foram transportados para o software estatístico SPSS. Diferenças demográficas entre os dois grupos foram reveladas pelo teste t de Student ou pelo teste exato de Fischer (IC95%; p>0,05). A associação e a correlação entre as respostas entre G-pp/ol e G-ol/pp durante cada coleta foram acessadas pelo teste t e o coeficiente de Pearson. Estratégia idêntica foi utilizada para as comparações intragrupo. RESULTADOS: Um total de 273 mulheres participou do estudo e 28 (10,2%) desistiram da segunda coleta. Não houve diferenças demográficas entre os grupos. Houve associação entre 15 das 19 questões do FSFI entre os dois grupos, tanto no teste quanto no reteste. A análise intragrupo revelou que todas as questões e os escores do FSFI estiveram associados, mas fracamente correlacionados para um mesmo grupo durante as duas coletas. CONCLUSÃO: A versão on-line do FSFI apresentou validade e confiabilidade aceitáveis quando comparada à versão em papel, o que pode justificar a opção por essa modalidade, especialmente em estudos envolvendo sexualidade.

Genetic analysis and cAMP measurement: comparison between lean and obese anovulating mice

PURPOSE: To evaluate genes differentially expressed in ovaries from lean (wild type) and obese (ob/ob) female mice and cyclic AMP production in both groups.METHODS: The expression on messenger RNA levels of 84 genes concerning obesity was analyzed through the PCR array, and cyclic AMP was quantified by the enzyme immunoassay method.RESULTS: The most downregulated genes in the Obesity Group included adenylate cyclase-activating polypeptide type 1, somatostatin, apolipoprotein A4, pancreatic colipase, and interleukin-1 beta. The mean decrease in expression levels of these genes was around 96, 40, 9, 4.2 and 3.6-fold, respectively. On the other hand, the most upregulated genes in the Obesity Group were receptor (calcitonin) activity-modifying protein 3, peroxisome proliferator activated receptor alpha, calcitonin receptor, and corticotropin-releasing hormone receptor 1. The increase means in the expression levels of such genes were 2.3, 2.7, 4.8 and 6.3-fold, respectively. The ovarian cyclic AMP production was significantly higher in ob/ob female mice (2,229±52 fMol) compared to the Control Group (1,814±45 fMol).CONCLUSIONS: Obese and anovulatory female mice have reduced reproductive hormone levels and altered ovogenesis. Several genes have their expression levels altered when leptin is absent, especially adenylate cyclase-activating polypeptide type 1.

The use of enzyme-linked immunosorbent assay and immunoblotting for the detection of Campylobacter fetus immunoglobulins in the cervico-vaginal mucus of female cattle

An indirect enzyme-linked immunosorbent assay was developed to detect antigen-specific secretory IgA antibodies to Campylobacter fetus subsp. venerealis in bovine vaginal mucus with a protein extract of the Campylobacter fetus subsp. venerealis by the acid glycine extraction method. Mean optical density measurement (λ=450 nm) was 0.143±0.9. The most immunoreactive protein bands of the Campylobacter fetus subsp. venerealis or Campylobacter fetus subsp. fetus recognized by IgA in immunoblotting, using bovine vaginal mucus samples, migrate at 42.6 kDa. The protein that migrates at 93 kDa was recognized exclusively for C. fetus subsp. venerealis. A positive vaginal mucus sample of a cow from negative herd recognized antigens of C. jejuni subsp. jejuni e C. fetus subsp. fetus.

Economic losses due to bovine brucellosis in Brazil

Brucellosis is an important zoonosis of worldwide distribution. Reliable epidemiologic brucellosis data covering approximately 90% of the cattle population in Brazil have been recently published. Therefore, considering the scarcity of information regarding the economic impact of bovine brucellosis in Brazil, the goal of this study was to estimate economic impact of brucellosis on the Brazilian cattle industry. Several parameters including abortion and perinatal mortality rates, temporary infertility, replacement costs, mortality, veterinary costs, milk and meat losses were considered in the model. Bovine brucellosis in Brazil results in an estimated loss of R$ 420,12 or R$ 226,47 for each individual dairy or beef infected female above 24 months of age, respectively. The total estimated losses in Brazil attributed to bovine brucellosis were estimated to be approximately R$ 892 million (equivalent to about 448 million American dollars). Every 1% increase or decrease in prevalence is expected to increase or decrease the economic burden of brucellosis in approximately 155 million Reais.

Immunodetection of myeloid and plasmacytoid dendritic cells in mammary carcinomas of female dogs

ABSTRACT: Dendritic cells have attracted great interest from researchers as they may be used as targets of tumor immune evasion mechanisms. The main objective of this study was to evaluate the relationship between the dendritic cells (DCs) subpopulation in simple type mammary carcinomas in female dogs. Two groups of samples were used: the control group consisted of 18 samples of mammary tissue without changes and the tumor group with 26 simple type mammary carcinomas. In these groups, we evaluated the immunodetection of immature and mature myeloid DCs, plasmacytoid DCs and MHC-II. In mammary tumor, mature myeloid DCs predominated in the peritumoral region, while immature myeloid DCs and plasmacytoid DCs were evident in the intratumoral region. Immunostaining of MHC-II was visualized in mammary acini (control group), in tumor cells and inflammatory infiltration associated with tumors. The comparison between the control and tumor groups showed a statistically significant difference between immature myeloid DCs, mature myeloid DCs and plasmacytoid DCs. The immunodetection of MHC-II was not significant when comparing the groups. The predominance of immature DCs in the tumor group is possibly related to an inefficient immune response, promoting the development and survival of tumor cells. The presence of plasmacytoid DCs in the same group suggests a worse prognosis for female dogs with mammary tumors. Therefore, the ability of differentiation of canine dendritic cells could be influenced by neoplastic cells and by the tumor microenvironment.

Physiologic parameters in female Red-billed curassows (Crax blumenbachii) in rehabilitation

Abstract: The present paper reports blood gas analysis, hematologic and micro bacteriologic information on four female Red-billed curassows, rescued from illegal wild animal trading, that were undergoing habilitation for reintroduction into the wild through Projeto Centrofauna/Botucatu-SP. There is a lack of physiological data on this species, endemic to the region of Atlantic Forest (Mata Atlântica), now under threat of extinction. This lack of information makes the clinical evaluation of these birds very difficult and has a direct and adverse effect on any of these birds received for medical treatment in hospitals, veterinary clinics and centers for research and conservation, as well as in reintroduction centers.

Survival analysis of female dogs with mammary tumors after mastectomy: epidemiological, clinical and morphological aspects

Abstract: Mammary gland tumors are the most common type of tumors in bitches but research on survival time after diagnosis is scarce. The purpose of this study was to investigate the relationship between survival time after mastectomy and a number of clinical and morphological variables. Data was collected retrospectively on bitches with mammary tumors seen at the Small Animal Surgery Clinic Service at the University of Brasília. All subjects had undergone mastectomy. Survival analysis was conducted using Cox's proportional hazard method. Of the 139 subjects analyzed, 68 died and 71 survived until the end of the study (64 months). Mean age was 11.76 years (SD=2.71), 53.84% were small dogs. 76.92% of the tumors were malignant, and 65.73% had both thoracic and inguinal glands affected. Survival time in months was associated with age (hazard rate ratios [HRR] =1.23, p-value =1.4x10-4), animal size (HRR between giant and small animals =2.61, p-value =0.02), nodule size (HRR =1.09, p-value =0.03), histological type (HRR between solid carcinoma and carcinoma in a mixed tumor =2.40, p-value =0.02), time between diagnosis and surgery (TDS, with HRR =1.21, p-value =2.7x10-15), and the interaction TDS*follow-up time (HRR =0.98, p-value =1.6x10-11). The present study is one of the few on the subject matter. Several important covariates were evaluated and age, animal size, nodule size, histological type, TDS and TDS*follow up time were identified as significantly associated to survival time.

Of milquetoasts and daredevils : personalities in female eiders

Traditionally biologists have often considered individual differences in behaviour or physiology as a nuisance when investigating a population of individuals. These differences have mostly been dismissed as measurement errors or as non-adaptive variation around an adaptive population mean. Recent research, however, challenges this view. While long acknowledged in human personality studies, the importance of individual variation has recently entered into ecological and evolutionary studies in the form of animal personality. The concept of animal personality focuses on consistent differences within and between individuals in behavioural and physiological traits across time and contexts and its ecological and evolutionary consequences. Nevertheless, a satisfactory explanation for the existence of personality is still lacking. Although there is a growing number of explanatory theoretical models, there is still a lack of empirical studies on wild populations showing how traditional life-history tradeoffs can explain the maintenance of variation in personality traits. In this thesis, I first investigate the validity of variation in allostatic load or baseline corticosterone (CORT) concentrations as a measure for differences in individual quality. The association between CORT and quality has recently been summarised under the “CORT-fitness hypothesis”, which states that a general negative relationship between baseline CORT and fitness exists. I then continue to apply the concept of animal personality to depict how the life-history trade-off between survival and fecundity is mediated in incubating female eiders (Somateria mollissima), thereby maintaining variation in behaviour and physiology. To this end, I investigated breeding female eiders from a wild population that breeds in the archipelago around Tvärminne Zoological Station, SW Finland. The field data used was collected from 2008 to 2012. The overall aim of the thesis was to show how differences in personality and stress responsiveness are linked to a life-history context. In the four chapters I examine how the life-history trade-off between survival and fecundity could be resolved depending on consistent individual differences in escape behaviour, stress physiology, individual quality and nest-site selection. First, I corroborated the validity of the “CORT-fitness hypothesis”, by showing that reproductive success is generally negatively correlated with serum and faecal baseline CORT levels. The association between individual quality and baseline CORT is, however, context dependent. Poor body condition was associated with elevated serum baseline CORT only in older breeders, while a larger reproductive investment (clutch mass) was associated with elevated serum baseline CORT among females breeding late in the season. Interestingly, good body condition was associated with elevated faecal baseline CORT levels in late breeders. High faecal baseline CORT levels were positively related to high baseline body temperature, and breeders in poor condition showed an elevated baseline body temperature, but only on open islands. The relationship between stress physiology and individual quality is modulated by breeding experience and breeding phenology. Consequently, the context dependency highlights that this relationship has to be interpreted cautiously. Additionally, I verified if stress responsiveness is related to risk-taking behaviour. Females who took fewer risks (longer flight initiation distance) showed a stronger stress response (measured as an increase in CORT concentration after capture and handling of the bird). However, this association was modulated by breeding experience and body condition, with young breeders and those in poor body condition showing the strongest relationship between risktaking and stress responsiveness. Shy females (longer flight initiation distance) also incubated their clutch for a shorter time. Additionally, I demonstrated that stress responsiveness and predation risk interact with maternal investment and reproductive success. Under high risk of predation, females that incubated a larger clutch showed a stronger stress response. Surprisingly, these females also exhibited higher reproductive success than females with a weaker stress response. Again, these context dependent results suggest that the relationship between stress responsiveness and risk-taking behaviour should not be studied in isolation from individual quality and that stress responsiveness may show adaptive plasticity when individuals are exposed to different predation regimes. Finally, female risk-taking behaviour and stress coping styles were also related to nest-site choice. Less stress responsive females more frequently occupied nests with greater coverage that were farther away from the shoreline. Females nesting in nests with medium cover and farther from the shoreline had higher reproductive success. These results suggest that different personality types are distributed non-randomly in space. In this thesis I was able to demonstrate that personalities and stress coping strategies are persistent individual characteristics, which express measurable effects on fitness. This suggests that those traits are exposed to natural selection and thereby can evolve. Furthermore, individual variation in personality and stress coping strategy is linked to the alternative ways in which animals resolve essential life-history trade-offs.

Female gametophyte development in Adesmia latifolia (Spreng.) Vog. (Leguminosae - Papilionoideae)

The female gametophyte has a monosporic origin and a Polygonum type development. The female gametophyte growth consumes a large part of the neighboring nucellar cells and, in the micropylar region, part of the nucellar epidermis and internal integument. The mature gametophyte is composed of only four cells due to the ephemeral characteristic of the antipodals. The synergids are pear-shaped cells with the formation of filiform apparatus. Their nuclei lie in the micropylar region and large vacuoles in the chalazal region, while the egg cell presents an opposite polarization. The central cell accumulates starch grains and the two polar nuclei approach the egg. Occasional development of two gametophytes was recorded. The closest to the micropyle develops fully, while the chalazal one remained in the tetranucleated stage. The embryological characters of A. latifolia are compared with those of other taxa within the Leguminosae, and the reproductive importance of multiple gametophyte formation for this species was discussed.

Deletion/inversion in the X-chromosome and increased telomeric associations in a female with primary amenorrhea

We describe a new case of a partial interstitial deletion and inversion of the long arm of the X-chromosome associated with a high incidence of telomeric associations in an 18-year old female who showed underdeveloped secondary sex characteristics, including small breasts and primary amenorrhea. Her karyotype was considered to be 46,X,del(Xq13 -> q22)inv(X)(q23-q27). The buccal mucosal cells showed absence of a typical Barr body, and the 5’-bromo-2-deoxyuridine incorporation studies revealed that neither the normal X-nor the abnormal X-chromosome was late replicating. The case is being presented for its extreme rarity

Vitamin D receptor alleles and bone mineral density in a normal premenopausal Brazilian female population

Studies on the association between vitamin D receptor (VDR) polymorphism and bone mineral density (BMD) in different populations have produced conflicting results probably due to ethnic differences in the populations studied. The Brazilian population is characterized by a very broad genetic background and a high degree of miscegenation. Of an initial group of 164, we studied 127 women from the city of São Paulo, aged 20 to 47 years (median, 31 years), with normal menses, a normal diet and no history of diseases or use of any medication that could alter BMD. VDR genotype was assessed by PCR amplification followed by BsmI digestion of DNA isolated from peripheral leukocytes. BMD was measured using dual energy X-ray absorptiometry (Lunar DPX) at the lumbar site (L2-L4) and femoral neck. Most of the women (77.6%) were considered to be of predominantly European ancestry (20.6% of them reported also native American ancestry), 12.8% were of African-Brazilian ancestry and 9.6% of Asian ancestry, 41.0% (52) were classified as bb, 48.8% (62) as Bb and 10.2% (13) as BB. The BB, Bb and bb groups did not differ in age, height, weight, body mass index or age at menarche. Lumbar spine BMD was significantly higher in the bb group (1.22 ± 0.16 g/cm²) than in the BB group (1.08 ± 0.14; P<0.05), and the Bb group presented an intermediate value (1.17 ± 0.15). Femoral neck BMD was higher in the bb group (0.99 ± 0.11 g/cm²) compared to Bb (0.93 ± 0.12) and BB (0.90 ± 0.09) (P<0.05). These data indicate that there is a significant correlation between the VDR BsmI genotype and BMD in healthy Brazilian premenopausal females.
