Rehabilitation and reintegration needs of female inmates and promotion mental health in Georgian prison

RESUMO: As mulheres presas encontram-se num sistema essencialmente dirigido por e concebido para homens. As mulheres que entram na prisão geralmente vêm de ambientes marginalizados e desfavorecidos e muitas vezes têm histórias de violência e abuso físico e sexual. As mulheres presas são um grupo particularmente vulnerável, uma vez que dentro do sistema prisional as suas necessidades de saúde e higiene são muitas vezes negligenciadas. O primeiro passo para o desenvolvimento de programas e práticas sensíveis ao género é compreender as características das mulheres delinquentes e definir fatores de vida específicos que contribuem para a formação do comportamento criminoso de mulheres. Em junho de 2012 foi realizada uma investigação na única prisão feminina da Geórgia, para estudar as necessidades mentais e psicossociais das mulheres presas. O objetivo da pesquisa foi o desenvolvimento de programas de apoio pertinentes para a reabilitação, ressocialização e reintegração, e a elaboração de recomendações práticas para a gestão das prisões. Foi desenvolvido um instrumento de pesquisa (inquérito) com uma fundamentação conceptual baseada em quatro principais teorias: Teoria dos Caminhos (Pathways Theory), teoria do desenvolvimento psicológico da mulher (Theory of Women’s Psychological Development), Trauma e Teorias da Dependência (Trauma and Addiction Theories). Foram inquiridas 120 mulheres presas. Os resultados deste estudo mostram que muitas das necessidades das mulheres presas são diferentes das dos homens e requerem estratégias adaptadas às suas características e situações psicossociais específicas. A maioria das mulheres encarceradas é jovem, enérgica, pode trabalhar, tem profissão e família. As presas sofrem de problemas psicológicos e muitas vezes são rejeitadas pelas suas famílias. Uma parte substancial das mulheres presas tem múltiplos problemas de saúde física e mental. A maioria delas tem filhos e sofre com o facto das crianças estarem a crescer longe da mãe. Com base nos resultados desta investigação é possível elaborar um contexto promotor do planeamento e desenvolvimento de serviços com um enfoque de género na prisão. Na perspetiva de longo prazo, o conhecimento das necessidades básicas e a introdução de programas e serviços com necessidades específicas pertinentes irá beneficiar as presas e as suas famílias, e melhorar a eficácia do sistema de justiça criminal.----------ABSTRACT: Female inmates find themselves in a system essentially run by men for men. Women who enter prison usually come from marginalized and disadvantaged backgrounds and are often characterized by histories of violence, physical and sexual abuse. Female prisoners constitute an especially vulnerable group given their specific health and hygienic needs within the system are often neglected. The first step in developing gender-sensitive program and practice is to understand female offenders’ characteristics and the specific life factors that shape women’s patterns of offending. In June 2012 a research was carried out in the Georgian only female prison facility to assess the mental and psychosocial needs of women prisoners, aiming to develop effective support programs for their rehabilitation, re-socialization and reintegration, as well as to elaborate new recommendations concerning prison management. A survey instrument (questionnaire) was developed within a theoretical framework based on four fundamental theories: Pathways Theory, Theory of Women’s Psychological Development and Trauma and Addiction Theories. Sample size was defined to be 120 surveyed persons. The study showed that needs of incarcerated women were different from those of men, thus requiring approaches tailored to their specific psychosocial characteristics and situations. The basic population of imprisoned women consisted of young, energetic, working-age females, most often with a professional qualification. Female prisoners suffered from psychological problems and are were more likely to be rejected by their families. Most of them had children and suffered that the children were growing without mothers. A substantial proportion of women offenders had multiple physical and mental health problems. Based on the study findings a conceptual framework can be elaborated towards planning and developing gender-sensitive services in prison. In the long-term perspective, acknowledgement of baseline needs and introduction of the relevant needs-specific programs and services may benefit women prisoners as well as their families, improving the effectiveness of the criminal justice system.

Active surveillance to determine the impact of methicillin resistance on mortality in patients with bacteremia and influences of the use of antibiotics on the development of MRSA infection

Introduction Methicillin-resistant Staphylococcus aureus (MRSA) is among the most important pathogens of nosocomial infections, mainly in intensive care units (ICUs), and accounts for 40-60% of all healthcare-associated S. aureus infections. We evaluated the incidence of nosocomial infection by S. aureus, identified the risk factors for MRSA infection, and evaluated the effect of resistance to methicillin on mortality in patients. Methods We conducted MRSA surveillance at a university hospital in Brazil from January 1, 2010, to December 31, 2010, and performed a retrospective case-control matched study to evaluate the frequency of subsequent MRSA bacteremia and death among patients. We evaluated and compared the risk factors between patients with MRSA and methicillin-sensitive Staphylococcus aureus (MSSA) infection. Results Sepsis was the most common cause of infection (17.7/1,000 patient-days), followed by surgical site (11.4/1,000 patient-days), pneumonia (4.1/1,000 patient-days), and urinary tract infection (2.4/1,000 patient-days). The significant risk factors were time of hospitalization, use of central vascular catheter (CVC), urinary catheter, nasogastric tube, parenteral nutrition, tracheostomy, mechanical ventilation, and previous antibiotic administration, the latter of which was the only independent risk factor for MRSA infection. Mortality was significantly higher in patients with MRSA. The number of antibiotics tested was not related to increases in the frequency of MRSA/1,000 patient-days. The incidence of mortality attributable to MRSA (bloodstream infection) BSI was 50%. Conclusions Surveillance results showed that the use of high levels of antibiotics was directly related to the development of MRSA infection, and the mortality attributable to MRSA in patients with bacteremia was significant.

Effect of feeding frequency on the reproductive efficiency of two species of Triatoma with different epidemiological importance

Introduction In Triatominae, reproductive efficiency is an important factor influencing population dynamics, and a useful parameter in measuring a species' epidemiological significance as a vector of Trypanosoma cruzi (Chagas, 1909). The reproductive efficiency of triatomines is affected by food availability; hence, we measured and compared the effects of feeding frequency on the reproductive parameters of Triatoma patagonica (Del Ponte, 1929) and Triatoma infestans (Klug, 1934), and the effects of starvation on T. patagonica. Methods Couples from both species were fed weekly, or every 3 weeks; in addition, females in couples of T. patagonica were not fed. Each couple was observed weekly and reproductive efficiency was assessed on the following parameters: fecundity (eggs/female), fertility (eggs hatched/eggs laid), initiation and end of oviposition, initiation of mating, number of matings/week, and number of reproductive weeks. Relative meal size index (RMS), blood consumption index (CI), and E values (eggs/mg blood) were also calculated. Results Changes in feeding frequency affected the reproductive parameters of T. patagonica only, with a decrease in fecundity and number of reproductive weeks for those fed every 3 weeks, or not fed. The reproductive period, RMS index, and CI were lower for T. patagonica than T. infestans. However, despite the lower fecundity of T. patagonica, this species required less blood to produce eggs, with an E values of 2 compared to 2.94 for T. infestans. Conclusions Our results suggest that the differences in fecundity observed between species reflect the availability of food in their natural ecotopes.

Study of the risk factors related to acquisition of urinary tract infections in patients submitted to renal transplant

INTRODUCTION: Urinary tract infections (UTI) among transplant recipients are usually caused by gram-negative microorganisms and can provoke a high incidence of morbidity and mortality. The aim of this study was to evaluate the risk factors associated with the acquisition of UTIs during the first year after renal transplantation. METHODS: Here, we report a single-center retrospective cohort study of 99 renal transplant patients followed for the first year after surgery. The definition of a UTI episode was a urine culture showing bacterial growth and leucocyturia when patients presented with urinary symptoms. The absence of infection (asymptomatic bacteriuria) was defined as an absence of symptoms with negative urine culture or bacterial growth with any number of colonies. RESULTS: Ninety-nine patients were included in the study. During the study, 1,847 urine cultures were collected, and 320 (17.3%) tested positive for bacterial growth. Twenty-six (26.2%) patients developed a UTI. The most frequent microorganisms isolated from patients with UTIs were Klebsiella pneumoniae (36%), with 33% of the strains resistant to carbapenems, followed by Escherichia coli (20%). There were no deaths or graft losses associated with UTI episodes. CONCLUSIONS: Among the UTI risk factors studied, the only one that was associated with a higher incidence of infection was female sex. Moreover, the identification of drug-resistant strains is worrisome, as these infections have become widespread globally and represent a challenge in the control and management of infections, especially in solid organ transplantation.

Reproductive biology of Bellucia (MELASTOMATACEAE)

The reproductive biology of five of the seven species of Bellucia (Melastomataceae), a genus of shrubs and small trees, was investigated in Amazonia. Sucessful fruit-set by Bellucia requires floral visitation by bees. The flowers are produced continuously all year, and are visited by a wide variety of female bees, the principal pollinators being Xylocopa, Centris, Ptilotopus, Epicharis, Eulaema, Bombus, and Oxaea. The floral attractants are color and the odor produced by the pollen, stamens, and petals; the reqard is pollen. Three species of Bellucia are self-incompatible. Indiscriminate visitor behavior and lack of phenological, morphological, or genetic barriers lead to hybridization between sympatric species of Bellucia, and no more than two species occupy the same habitat at anu one locality. Bellucia produces berries with numerous small seeds, and is dispersed by birds, bats, monkeys, tapirs, turtles, and ants. Seedling establisment requires full sunlight, and occurs on a variety of soil types. The reproductive strategy is interpreted as that of a pioneer species.

Heliconia acuminata reproductive success is independent of local floral density

Reproductive plants in tropical forests are patchily distributed, with some in large aggregations of reproductive consepecifics while others are relatively isolated. This variation in floral density is hypothesized to have a major effect on plant reproductive success, since individuals in higher density neighborhoods can attract more or higher quality pollinators. We experimentally tested this hypothesis with populations of the understory herb Heliconia acuminata in central Amazonia. We created replicated plots in which reproductive plant density spanned the range of naturally occurring floral neighborhood size, then measured three surrogates of plant fitness in focal plants in each array. There was no significant difference between any of the three floral neighborhood treatments in total seed production, fruit set, or the number of seeds produced per fruit. Pollinator visitation rates to plants in all treatments were extremely low, with many plants not visited at all during the observation period. This could be because H. acuminata's hummingbird pollinators are unable to find the widely scattered reproductive plants, however this hypothesis appears unlikely. Instead, natural flowering plant densities may simply be below the threshold value at which neighborhood effects become important, even in "high-density" aggregations. Nutrient limitation, selective fruit abortion, and reproduction via male rather than female function may also be playing a role. We argue the absence of neighborhood effects may be a general phenomenon in central Amazonian forests, though additional experiments with other plant-pollinator systems are needed to determine the extent to which this hypothesis is supported.

Reproductive biology of Amasonia obovata Gleason (Laminaceae)

Floral mechanisms that ensure seed production via autogamy are more likely to occur in species growing in environments where pollination is scarce. Amasonia obovata was studied in the State of Mato Grosso-Brazil, from 2009 to 2012, to analyze the morphological and reproductive characteristics, aside from investigating the association of the reproductive success with the pollinator frequency and identity. The flowering and fruiting of A. obovata was concentrated in a period of five months during the rainy season. The dichogamy in flowers of A. obovata is not clearly defined, since the sexual functions were overlapped in the male and female phases. The species is self-compatible and not apomictic. The fruiting percentage obtained by hand self-pollination did not differ from cross-breeding (F = 0.74, P =0.39). In the observations from 2010 to 2012, a hummingbird (Thalurania furcata) legitimate visited 20-100% of the flowers in the male and female phases on different A. obovata plants. Due to the high frequency, this hummingbird was considered the single potential pollinator of the species. These findings show that a limited availability of pollinators may select for floral traits and plant mating strategies that lead to a system of self-fertilization.

Reproductive biology of Ameerega trivittata (Anura: Dendrobatidae) in an area of terra firme forest in eastern Amazonia

The reproductive success of tropical amphibians is influenced by factors such as body size and the characteristics of breeding sites. Data on reproductive biology are important for the understanding of population dynamics and the maintenance of species. The objectives of the present study were to examine the abundance of Ameerega trivittata, analyze the use of microhabitats by calling males and the snout-vent length (SVL) of breeding males and females, the number of tadpoles carried by the males and mature oocytes in the females, as well as the relationship between the SVL of the female and both the number and mean size of the mature oocytes found in the ovaries. Three field trips were conducted between January and September, 2009. A total of 31 plots, with a mean area of 2.3 ha, were surveyed, resulting in records of 235 individuals, with a mean density of 3.26 individuals per hectare. Overall, 66.1% of the individuals sighted were located in the leaf litter, while 17.4% were perched on decaying tree trunks on the forest floor, 15.7% on the aerial roots of Cecropia trees, and 0.8% on lianas. Males were observed transporting a mean of 10.8 tadpoles on their backs. A significant correlation was found between the size of the females and the mean diameter of the oocytes. New data were collected on the size of oocytes and no pattern was found in the type of perches used by calling males of the different Ameerega species.

Biodegradable drug-eluting stents: Targeting urothelial tumors of upper urinary tract

INTRODUCTION & OBJECTIVES: Urothelial tumors of upper urinary tract are ranked among the most common types of cancers worldwide. The current standard therapy to prevent recurrence is intravesical Bacillus Calmetteâ Guerin (BCG) immunotherapy, but it presents several disadvantages such as BCG failure and intolerance. Another way is to use chemotherapy, which is generally better tolerated that BCG. In this case, drugs such as epirubicin, doxorubicin, paclitaxel and gemcitabine are used. Nevertheless, intravesical chemotherapy only prevents recurrence in the short-term. These failings can be partially attributed to the short residence time and low bioavailability of the drug within the upper urinary tract and the cancer cells, resulting in a need for frequent drug instillation. To avoid these problems, biodegradable ureteral stents impregnated by supercritical fluid CO2 (SCF) with each of the four anti-cancer drugs were produced. MATERIAL & METHODS: Four formulations with different concentrations of gelatin and alginate and crosslink agent were tested and bismuth was added to confer radiopaque properties to the stent. The preliminary in vivo validation studies in female domestic pigs was conducted at the University of Minho, Braga, after formal approval by the institutionâ s review board and in accordance with its internal ethical protocol for animal experiments. Paclitaxel, epirubicin, doxorubicin and gemcitabine were impregnated in the stents and the release kinetics was measured in artificial urine solution (AUS) for 9 days by UV spectroscopy in a microplate reader. The anti-tumoral effect of the developed stents in transitional cell carcinoma (TCC) and HUVEC primary cells, used as control, was evaluated. RESULTS: The in vivo validation of this second-generation of ureteral stents performed was herein demonstrated. Biodegradable ureteral stents were placed in the ureters of a female pigs, following the normal surgical procedure. The animals remained asymptomatic, with normal urine flow. The in vitro release study in AUS of the stent impregnated showed a higher release in the first 72h for the four anti-cancer drugs impregnated after this time the plateau was achieved and the stent degraded after 9 days. The direct and indirect contact of the anti-cancer biodegradable stents with the TCC and HUVEC cell lines confirm the anti-tumor effect of the stents impregnated with the four anti-cancer drugs, reducing around 75% of the viability of the TCC cell line after 72h and no killing effect in the HUVEC cells. CONCLUSIONS: The use of biodegradable ureteral stent in urology clinical practice not only reduce the stent-related symptoms but also open new treatment therapyâ s, like in urothelial tumors of upper urinary tract. Furthermore, we have demonstrated the clinical validation in vivo pig model. This study has thus shown the killing efficacy of the anti-cancer drug eluting biodegradable stents in vitro for the TCC cell line, with no toxicity observed in the control, non-cancerous cells.The direct and indirect contact of the anti-cancer biodegradable stents with the TCC and HUVEC cell lines confirm the anti-tumor effect of the stents impregnated with the four anti-cancer drugs, reducing around 75% of the viability of the TCC cell line after 72h and no killing effect in the HUVEC cells. This study has thus shown the killing efficacy of the anti-cancer drug eluting biodegradable stents in vitro for the TCC cell line, with no toxicity observed in the control, non-cancerous cells.

Mortality due to cardiovascular disease in women during the reproductive age (15 to 49 years), in the State of São Paulo, Brazil, from 1991 to 1995

OBJECTIVE: To describe mortality due to cardiovascular diseases in women during the reproductive age (15 to 49 years) in the state of São Paulo, Brazil, from 1991 to 1995. METHODS: A list of all deaths and their underlying causes, coded according to the International Classification of Diseases, 9th revision, multiple causes of death, and estimates of the female population according to age groups were provided by the SEADE Foundation. Specific coefficients for 100 thousand women for each year as well as the medians of these coefficients related to 5 years, and the percentage of death by subgroups were calculated. RESULTS: Cerebrovascular diseases have the highest coefficients (14.24 for 100 thousand females), followed by ischemic heart disease (7.37), other heart diseases (6.39), hypertensive disease (3.03), chronic rheumatic heart disease (1.58), pulmonary vascular diseases (1.29), and active rheumatic fever (0.05). Systemic arterial hypertension, as an associated cause, occurred in 55.3% to 57.8% of all the deaths due to intracerebral hemorrhage and in 30.4% to 30.8% due to subarachnoid hemorrhage. CONCLUSION: The significance of cerebrovascular diseases, coronary artery disease, and systemic arterial hypertension as causes of mortality suggests the need to emphasize preventive actions for young women who have the potential to reproduce to avoid possible complications in future pregnancies, and premature mortality.

Estudio de la muerte celular por Apoptosis en el ovario de Columba maculosa y Columbina picui (Aves:Columbidae) durante el Ciclo Reproductivo Anual. Study of cell death by apoptosis in the ovary of Columba maculosa and Columbina picui (Aves: Columbidae) during the reproductive annual cycle.

En este trabajo se analizarán las características estructurales, cuantitativas y el proceso de muerte celular por apoptosis en el ovario de C. maculosa y C.picui con el objetivo de aportar conocimientos básicos a la biología reproductiva de estas aves. Cincuenta hembras adultas de cada especie se capturarán en el Dpto. Río Primero (Pcia. de Cba), R. Argentina, durante el ciclo reproductivo 2011-2012. Las muestras de ovarios se fijaran en Formalina Neutra pH 7.0, procesarán con la técnica de inclusión en parafina y colorearan con Hematoxilina /Eosina y Reacción Nuclear de Feulgen. Cinco muestras serán utilizadas para la determinación de muerte celular por apoptosis con la técnica de TUNEL. Se estudiarán las características morfohistológicas del ovario de C.maculosa y C. picui e identificarán, categorizarán y cuantificarán los folículos atrésicos no bursting (folículos atrésicos previtelogénicos y vcitelogénicos pequeños que conservan la integridad de la pared folicular) y bursting (folículos vitelogénicos mayores de 2 mm que liberar el contenido folicular por ruptura de la pared folicular) durante el ciclo reproductivo anual. Mediante la marcación de ADN fragmentado, se revelará la muerte celular por apoptosis en las células granulosas de los folículos atrésicos. Se compararán las semejanzas y diferencias estructurales y cuantitativas y el proceso de muerte celular en los folículos regresivos entre las dos especies. Los resultados de este trabajo representarán un importante aporte al conocimiento de la atresia folicular como así también a la muerte celular, un proceso estrechamente asociado a la misma, aún poco estudiado en el ovario de las aves. In this work we analyse the structural, quantitative and the process of the cell death by apoptosis in the ovary of Columba maculosa and Columbina picui in order of providing basic knowledge of reproductive biology of these birds. Fifty adult female of each species will be caught in the Río Primero (Pcia. Cba) R.Argentina, during 2011 - 2012. The ovarian samples will be fixed en neutral buffered Formalin (pH 7.0), processed with the technique of inclusion in paraffin and stained with Haematoxylin - Eosin, and nuclear Reaction of Feulgen. Five samples will be used to reveal cell death by apoptosis with the technique of TUNEL. Will be studied the morphohistological characteristics of ovary of both species, and identify, categorize and quantify the atretic follicles over the cycle, the non-bursting (pre-vitellogenic follicles and vitellogenic small < 2 mm, involution an without follicular rupture) and bursting (vitellogenic follicle > 2 mm in the which the yolk falls into the peritoneum due to rupture of with out put of the wall follicular). Will be revealed DNA fragmentation in the granulosa cells of the atretic follicles. Will compared the similaritues and differences in structure and quantitative and the cell death process by apoptosis in the regresive follicles, between the two species. The results of this study represent an important contribution to the knowledge of follicular atresia as well cell death a process closely associated with it and still poorly studied in the ovary of birds.

Estrategias reproductivas de lagartos del género tupinambis en distintos contextos ecológicos de la Provincia de Córdoba. Reproductive strategies of lizards of genus tupinambis in different ecological contexts of the Cordoba province.

Los caracteres de historia de vida son sensibles a la variación histórica o actual de los factores ambientales. Estudiar dicha variabilidad mediante la realización de estudios comparativos permite obtener evidencias sobre las causas de la evolución de ciertos caracteres. Los lagartos son excelentes modelos para el estudio de selección sexual y evolución del comportamiento social y reproductivo debido a que su relativa baja dispersión podría tener consecuencias evolutivas profundas en el desarrollo de distintas estrategias, ya que las poblaciones, al encontrarse más aisladas, podrían verse influenciadas por las fuerzas selectivas locales, mostrando una alta heterogeneidad espacial y temporal. Por eso nos propusimos realizar este trabajo para evaluar si existen diferentes estrategias reproductivas en los lagartos del género Tupinambis en distintos contextos ecológicos de la provincia de Córdoba. Para ello analizaremos distintas características de la historia de vida en poblaciones de estas especies tales como estructura de tamaño, sexo operativo, frecuencia reproductiva, tamaño de camada, condición corporal reproductiva, tamaño de madurez sexual, características espermáticas, elección de sitios de nidificación, etc. Además analizaremos la estructura genética de las poblaciones para inferir procesos demográficos históricos y patrones actuales de flujo génico y conectividad. The life history traits are sensitive to historical or current variation of environmental factors. Studying this variability by performing comparative studies allows obtaining evidence on the causes of the evolution of certain characters. Lizards are excellent models for studying sexual selection and evolution of social and reproductive behavior because their relatively low dispersal capabilities could have profound evolutionary consequences in the development of different strategies, since isolated populations may be stronger influenced by local selective forces, showing a high spatial and temporal heterogeneity. We decided to perform this study to assess whether there are different reproductive strategies in lizards of the genus Tupinambis in different ecological contexts of the Cordoba province. We will analyze different life history traits in populations of these species such as size structure, operational sex ratio, reproductive frequency, litter size, body condition, size at sexual maturity, sperm characteristics, choice of nesting sites, etc.. We also analyzed the genetic structure of populations to infer historical demographic processes and current patterns of gene flow and connectivity.
