Despite the increasing public profile of lesbian childbearing, public health resources for expectant women often bear heterosexist assumptions and create barriers to accessing information relevant to lesbian mothering experiences. This descriptive, exploratory study examined one lesbian couple's perceived educational needs for effective support, barriers to access, strategies for locating care, and the impact of childbearing on their lives, as well as their reflections on inviting ways to offer supportive practices in a public health context. A case study approach used feminist ethnographic methodology and purposeful convenience sampling. A prenatal and a postnatal open-ended interview were completed with 1 white, middle-class, able, lesbian childbearing couple, each ofwhom has birthed as coparent and biological mother in this couple relationship. Despite this couple's immense situated privilege, they struggled to locate the support they sought for childbearing in a way that offered optimal emotional and physical care from the preconceptual to postpartum stages and which maintained confidentiality or anonymity as desired. They created meaningful care through personal networks. The findings were framed using invitational and feminist theories: how people, places, programs, processes, policies, and politics contributed to educational support. A three part conceptual framework emerged which identified components of access to support: perceived safety of resources, disclosure status, situated privilege, and public or private availability of information. The consequences of lack of public access to comprehensive childbearing care for lesbian women and their communities are described. Educational possibilities addressed systemic heterosexism through the development of sensitive educators, meaningful curriculum, program planning, explicit policies, community partnerships, and political leadership with respect to both institutional and research venues.

This study presents infonnation gathered during personal interviews in which participants were asked how they, as physical educators, might possibly assist the victim of bullying through their programs. The research is a qualitative study, using an inductive approach. Five participants were chosen, based on convenience sampling, with semi-structured interviews which were audio recorded. The theoretical research found that the most stable characteristics of victimized boys were lack of strength and lack of physical fitness. This suggested that Physical Education class might be the best place in which to empower victimized students to reduce their own victimization by addressing these areas of strength and fitness. From the interviews it became clear that, while these educators showed a willingness to help bullying victims through their programs, their adherence to a Physical Education model based primarily on elitism, as opposed to individual fitness, would make it difficult for them to do so effectively.

This thesis describes college and university students' smoking behaviours and examines whether socioenvironmental and personal characteristics experienced during adolescence are differentially associated with their smoking participation. Results show more college students than university students currently smoke (37% and 21 % respectively) and more began smoking prior to post-secondary school (93% and 84% respectively). Early age of onset of alcohol use increased the odds of current smoking (main effect model, OR = 8.56 CI = 6.47, 11.33), especially for university students (interaction effect model, b = 2.35 CI = 7.50, 14.64). Lower levels of high school connectedness were associated with increased odds of current smoking but for university students only (interaction effect model, b = -0.15 CI = 0.84, 0.88). While limitations associated with convenience sampling and low response rate exist, this is the first Canadian study to examine college and university students separately. I t reveals that tobacco control programming needs to differ for college and university students, and early alcohol prevention and school engagement programs for adolescents may influence tobacco use. Given that both educational pathway and use of tobacco are associated with SES, future research may consider examining in more detail, SES-related socioenvironmental variables.

Geographically, Taiwan is an Island and situated in the northeast of Asia, on the western side of the Pacific Basin, at the southeast of main China, south of Japan, and north of the Philippines. The main topographic character is the longitudinally oriented mountainous area. More than 200 peaks rise above 3000 m. They departed Taiwan into two lowland areas, an eastern and western plain. Taiwan is departed into subtropical (north area) and tropical zone (south area), which have a warm and humid climate, due to the Tropic of Cancer passing through. The average annual temperature in the lowland amounts to 28°C (7~38°C). The temperate climate also presents in the mountainous areas. The tropical typhoons usually come in summer and bring heavy rain, while the monsoon seasons have an important effect on the regional rainfall distribution. The mean annual rainfall of Taiwan is about 2600 mm (1000~6700 mm); the mountainous areas receive more rain than the lowlands. In Taiwan, according to different temperature and vegetation, the ecological environments were given rise to vertical biotic zonations, and form five major types: highland snowfield, highland meadow, coniferous forest, deciduous forest, and tropical forest. Six National Parks in Taiwan are located in the mountainous areas, in the north, the south, and on Jinmen Island. The National Parks represent about 8.4% of the country area. In this study, the collection sites are situated in Yangmingshan, Shei-Pa, Yushan, and Kenting National Park. Due to the island isolation, the proportions of endemic species are great in Taiwan, which also presents a high biodiversity. There are 4255 species of vascular plants including 1133 endemic. 5936 species in 1276 genera of fungi are hitherto reported in Taiwan. Among them, 233 Corticiaceae species were recorded, over one third (79 species) of them are known only from Taiwan. The first fungal report in Taiwan is about Phytophthora cyperi, published by the Japanese researcher T. Kawakami in 1904. Therefore, the history of research about fungi in Taiwan is more than one hundred years old. An eminent Japanese mycologist K. Sawada made an intensive survey from 1919 to 1959, and reported 2464 fungi species in his eleven volumes of “Descriptive Catalogue of Formosan Fungi”. However, only a few species (21 species in 9 genera) of Corticiaceae were recorded. From 1973, Chen and Lin resumed the study on Corticiaceae, and also some other foreign mycologists contributed for this field after 1980. The German research group lead by Franz Oberwinkler from Tübingen University collected in Taiwan several times. They published a number of new species and new records. Since 1989, S. H. Wu, a Taiwanese mycologist, has published a great amount of reports on corticioid fungi from Taiwan. Corticioid fungi were made up by the large and heterogeneous unnatural family Corticiaceae and other resupinate fungi belonging to other natural families in the Agaricomycetes. Molecular studies have shown that corticioid genera are distributed across all major clades of Agaricomycetes indicating that the corticioid fungi represent a polyphyletic group. They have resupinate fruitbodies and similar habitats. Species are characterized by simple fruitbody, more or less effused, and present smooth, porioid, grandinioid to odontioid hymenial surface. The fruitbodies are differently colored and usually soft to tough. Most of the Corticiaceae species are wood-saprobic organisms and gain the energy from the decomposing of wood-substrate such as cellulose or lignin. Materials for this study were collected by the author and other mycologists in Taiwan during surveys in April and May 1996, and March 2007, using the spring season with its high humidity and warm climate which are optimal conditions for the development of fungi. For assembling, the convenience sampling method was used in this study. This approach was chosen because it enables to detect a high biodiversity in a short time, and also to find species with rare or patchy distribution. The collecting sites from the North to the South include four National Parks and some preserved forests. They cover many different habitats such as low lands and high mountains. Fresh specimens were dried and analysed with a light microscope. 265 specimens belonging to Corticiaceae were studied in this research. Among them, 50 species in 21 genera including 11 new records and 10 new species were described with text and drawing. Four new species are belonging to Hyphodontia (H. sp. nov. 1, H. sp. nov. 2, H. sp. nov. 3, and H. sp. nov. 4), four to Schizopora (Sch. sp. nov. 1, Sch. sp. nov. 2, Sch. sp. nov. 3, and Sch. sp. nov. 4), one in Trechispora (T. sp. nov. 1), and one in Tubulicrinis (T. sp. nov. 1). Species recorded as new are Aleurodiscus amorphus, Botryohypochnus isabellinus, Hyphodontia cineracea, Hyphodontia palmae, Hypochnicium vellereum, Merulius tremellosus, Metulodontia nivea, Paullicorticium ansatum, Phlebia radiata, Phlebiella ardosiaca, and Xylobolus frustulatus. Besides, Botryohypochnus, Merulius, Metulodontia, Paullicorticium, and Xylobolus are also newly recorded genera in Taiwan. The genus Hyphodontia presents the highest diversity with 20 out of 50 species recorded. The second important genus is Hyphoderma, however with only 5 species. This indicates that Hyphodontia and Hyphoderma have a higher ability to develop in variable environments and approximately shows the predominance of these two genera in Taiwanese Corticiaceae. There are 11 new records out of the 50 species recorded, representing 22%. Some species, e.g. Hypochnicium vellereum and Paullicorticium ansatum were in the past recorded only in Europe and North America with cold and temperate climate. The samples of them are for the first time found in the subtropical belt, and display some difference from those of temperate regions. These collections should be molecularly investigated to clarify if they represent the same species of temperate areas. Patchily distributed species, for example Phlebiella ardosiaca, previously known only in Europe, and Hyphodontia palmae collected only in Brazil, were first recorded in different continents. Two possibilities are indicated by these new records: they are worldwide species but very rare to be found, or the Taiwanese specimens are taxonomically different. More survey from other continents and molecular study for these collections should be done in the future to solve this question. The distribution of Corticiaceae in Taiwan presents the variations in the north, central, and south areas and shows the diversity in lowlands and high mountains. The results of this study provide the evidence that the temperate Corticiaceae species displays a wider distribution. Subtropical and tropical taxa probably have also high dispersal capacities, and could possibly be found in the future in neighboring areas such as China, Japan, Korea or South Asia, but this needs further researches. In the total of 50 species, 10 new taxa were described in this study, giving about 20%. Some new species (e.g. Hyphodontia sp. 1, Hyphodontia sp. 2, and Hyphodontia sp. 3) are very similar to known species (Hyphodontia sambuci and Hyphodontia formosana), and the distinctive characters of Schizopora sp. nov. 1 are intermediate between those of Schizopora paradoxa and Hyphodontia flavipora. Thus, these small differences between the new and known species, suggest that the speciation occurred when the fungi migrated into Taiwan, due to the high diversity of environment, and amounts of the endemic plants. Taiwan is an intermediate place for the south (tropical) fungal species to migrate and adapt to north (temperate) regions. The middle and high altitude environments in Taiwan offer good conditions for the fungal speciation and possibly the occurrence of physiological changes to adapt to the temperate climate. Thus Taiwan has an important position for the biogeography of Asia mycobiota. 5936 known species in Taiwan represent about only 20% of the estimated number (24000) of Taiwanese fungal taxa. In this study, the findings (22% new records and 20% new species) indicate that amounts of unknown fungi species are expected in Taiwan. The lack of knowledge indicates that many new species are awaiting description, and fungal survey in Taiwan remains in a Pioneer phase. The last three wide surveys of Corticiaceae researches took place 20 years before this study (Chen & Lin 1977, Lin & Chen 1989, Wu 1990). After previous important contributions, the present taxonomic study comprising 21 genera is the most extensive on Corticiaceae of Taiwan.

Introducción: Los desórdenes músculo-esqueléticos se pueden describir como una de las causas más frecuentes de patologías de origen laboral. Según estudios, el ausentismo laboral está asociado con enfermedades derivadas del sedentarismo, las enfermedades respiratorias, las afecciones osteomusculares y los traumatismos. Se pretende establecer la relación entre los síntomas musculo-esqueléticos y el ausentismo laboral en una IPS de Bogotá D.C. especializada en salud sexual y reproductiva, teniendo en cuenta el tipo de trabajo y hábitos en la práctica de actividad física del personal. Metodología: Se realizó un estudio de corte transversal, para evaluar la presencia de síntomas músculo-esqueléticos en la IPS mencionada, que cuenta con 4 centros ubicados en Bogotá D.C. La evaluación de los síntomas musculo-esqueléticos se realizó por medio del “Cuestionario Nórdico” y la práctica de actividad física de los trabajadores se evaluó con la aplicación de preguntas extraídas de la Encuesta Nacional de la Situación Nutricional (ENSIN). Mediante un muestreo por conveniencia se incluyó una muestra representativa de la población. Resultados: Se incluyeron143 trabajadores de la salud en la muestra. Los síntomas musculo-esqueléticos más frecuentes fueron: en el cuello (48.2%) seguido de columna lumbar (45.4%) y mano/muñeca derecha (41.2). El 95.1% de los trabajadores presentaron algún síntoma músculo-esquelético, algunos de ellos con afectación en más de 1 segmento.

Este é um estudo exploratório e correlacional, com um número inicial de 150 participantes, utilizando uma amostra de conveniência constituída por cinco clínicas médicas e cinco casas de medicina tradicional chinesa, em Lisboa, onde os indivíduos foram autorizados a responder voluntariamente a questionários. Apresenta uma taxa de resposta de 74% (N=111). A adesão à acupunctura é maior no sexo feminino e na faixa etária de 31 a 50 anos (40% homens e 48% mulheres). A procura de tratamento de problemas musculares e articulares e para problemas do foro psicológico são as mais descritas, apesar de ser referida como eficaz noutro tipo de queixas, e não ser o primeiro tipo de tratamento que a população procura. É reconhecido que os resultados podem ocorrer a médio e longo prazo, após várias sessões terapêuticas, o que não parece afetar a perceção da população em estudo que se diz satisfeita (53%) com uma muita boa e / ou boa relação benefício-custo. Em geral, a maioria da população (93%) confia na terapia pelo resultado bom ou muito bom (79%) ou razoável (16%) obtido, e deposita confiança (88%) nas competências do profissional de saúde que executa a acupunctura.

Objective: Fecal loading, cognitive impairment, loose stools, functional disability, comorbidity and anorectal incontinence are recognized as factors contributing to loss of fecal continence in older adults. The objective of this project was to assess the relative distribution of these factors in a variety of settings along with the outcome of usual management. Methods: One hundred and twenty adults aged 65 years and over with fecal incontinence recruited by convenience sampling from four different settings were studied. They were either living at home or in a nursing home or receiving care on an acute or rehabilitation elderly care ward. A structured questionnaire was used to elicit which factors associated with fecal incontinence were present from subjects who had given written informed consent or for whom assent for inclusion in the study had been obtained. Results: Fecal loading (Homes 6 [20%]; Acute care wards 17 [57%]; Rehabilitation wards 19 [63%]; Nursing homes 21 [70%]) and functional disability (Homes 5 [17%]; Acute care wards 25 [83%]; Rehabilitation wards 25 [83%]; Nursing homes 20 [67%]) were significantly more prevalent in the hospital and nursing home settings than in those living at home (P < 0.01). Loose stools were more prevalent in the hospital setting than in the other settings (Homes 11 [37%]; Acute care wards 20 [67%]; Rehabilitation wards 17 [57%]; Nursing homes 6 [20%]) (P < 0.01). Cognitive impairment was significantly more common in the nursing home than in the other settings (Nursing homes 26 [87%], Homes 5 [17%], Acute care wards 13 [43%], Rehabilitation wards 14 [47%]) (P < 0.01). Loose stools were the most prevalent factor present at baseline in 13 of the 19 (68%) subjects whose fecal incontinence had resolved at 3 months. Conclusion: The distribution of the factors contributing to fecal incontinence in older people living at home differs from those cared for in nursing home and hospital wards settings. These differences need to be borne in mind when assessing people in different settings. Management appears to result in a cure for those who are not significantly disabled with loose stools as a cause for their fecal incontinence, but this would need to be confirmed by further research.

OBJETIVO: Identificar indivíduos responsivos à tetrahibrobiopterina (BH4) em uma amostra de pacientes brasileiros com hiperfenilalaninemia por deficiência de fenilalanina-hidroxilase (HPA-PAH). MÉTODOS: Estudo intervencional, amostragem por conveniência. Para serem incluídos no estudo, os pacientes deveriam: possuir diagnóstico bioquímico de HPA-PAH; ter idade ≥ 7 anos; estar em tratamento dietético; e apresentar níveis de fenilalanina (Phe) ≥ 6 mg/dL em todas as medidas realizadas no ano anterior à inclusão no estudo. Os níveis de Phe foram determinados por meio de espectrometria de massas in tandem no dia anterior (dia 1) e nos pontos de hora 0, 4 e 8 h (dia 2) e 24 h (dia 3) após ingestão de BH4. Os critérios utilizados para definir responsividade ao BH4 foram: critério 1-redução ≥ 30% de Phe após 8 h da administração de BH4; e critério 2-redução ≥ 30% de Phe após 24 h da administração. RESULTADOS: Dezoito pacientes foram incluídos no estudo (mediana de idade = 14 anos, sexo masculino = 12). Cinco pacientes foram responsivos ao BH4, sendo três (forma clássica: um; forma leve: dois) de acordo com ambos os critérios, e dois (forma clássica: um; forma não definida: um) de acordo com o critério 2. Os níveis de Phe plasmáticos do dia 1 não demonstraram variação nos pontos de hora (p = 0,523). Entretanto, quando comparamos os níveis de Phe nos pontos de hora dos dias 1 e 2, encontramos uma variação significativa (p = 0,006). A análise da associação genótipo-fenótipo confirmou o caráter multifatorial da responsividade ao BH4. CONCLUSÃO: Os nossos achados estão de acordo com a literatura e indicam que um número relevante de pacientes brasileiros com HPA-PAH é responsivo à BH4.

Patient discharge from post-anesthetic recovery (PAR) depends, among other factors, on normothermia and the patient's score on the Aldrete-Kroulik index. The objective of this study was to verify the relationship between the Aldrete-Kroulik index and body temperature in patients. This study was performed at the University of Sao Paulo University Hospital. Convenience sampling was used, and the sample consisted of 60 patients of ages between 18 and 60 years who underwent general anesthesia. The patients' body temperature was obtained by tympanic measurement, and the Aldrete-Kroulik index was measured on admission and at discharge from post-anesthetic recovery. The data were processed using SPSS, considering a significance level of 5%, and the Spearman and Wilcoxon tests were applied. In conclusion, no significant correlation was found between the two parameters for discharge.

This article reports the findings from an online survey of nursing faculty from the United States, Canada, Latin America, and Caribbean countries to identify their perceptions about global health competencies for undergraduate nursing students. A list of global health competencies for medical students developed by the Association of Faculties of Medicine of Canada Resource Group on Global Health and the Global Health Education Consortium was adapted for nurses and translated from English to Spanish and Portuguese. The competencies were divided into six subscales, and respondents rated each competency on a 4-point Likert scale, with high scores reflecting strong agreement that the competency was essential for undergraduate nursing students. E-mail invitations and links to the online survey were distributed using a nonprobability convenience sampling strategy. This article reports findings only from the respondents to the English and Spanish surveys. The final sample included 542 responses to the English survey and 51 responses to the Spanish survey. Cronbach's alpha reliability coefficients for the subscales ranged from .78 to .96. The mean values for all 6 subscales and for each of the 30 items were greater than 3.0 for the respondents to the Spanish survey, and the mean values for 27 of the items were greater than 3.0 for the respondents to the English survey. These findings suggest that respondents perceived the competencies as essential global health competencies for undergraduate nursing students in the Americas. Narrative comments written by respondents indicate additional competencies and specific concerns about adding additional content to an already full curricula. Results of this study can be used to guide faculty deliberations about global health competencies that should be incorporated in the nursing curricula.

BACKGROUND Delayed-onset muscle soreness (DOMS) is a common symptom in people participating in exercise, sport, or recreational physical activities. Several remedies have been proposed to prevent and alleviate DOMS. DESIGN AND METHODS A five-arm randomized controlled study was conducted to examine the effects of acupuncture on eccentric exercise-induced DOMS of the biceps brachii muscle. Participants were recruited through convenience sampling of students and general public. Participants were randomly allocated to needle, laser, sham needle, sham laser acupuncture, and no intervention. Outcome measures included pressure pain threshold (PPT), pain intensity (visual analog scale), and maximum isometric voluntary force. RESULTS Delayed-onset muscle soreness was induced in 60 participants (22 females, age 23.6 ± 2.8 years, weight 66.1 ± 9.6 kg, and height 171.6 ± 7.9 cm). Neither verum nor sham interventions significantly improved outcomes within 72 hours when compared with no treatment control (P > 0.05). CONCLUSIONS Acupuncture was not effective in the treatment of DOMS. From a mechanistic point of view, these results have implications for further studies: (1) considering the high-threshold mechanosensitive nociceptors of the muscle, the cutoff for PPT (5 kg/cm) chosen to avoid bruising might have led to ceiling effects; (2) the traditional acupuncture regimen, targeting muscle pain, might have been inappropriate as the DOMS mechanisms seem limited to the muscular unit and its innervation. Therefore, a regionally based regimen including an intensified intramuscular needling (dry needling) should be tested in future studies, using a higher cutoff for PPT to avoid ceiling effects.

Little is known about how sleep disruption impacts physical health among the homeless. The association between homelessness, quality of sleep and physical health were investigated in the current study. Convenience sampling was used to select participants from a pool of people attending the programs of Ecclesia Ministries. Interviews were conducted with 32 persons from the Boston metropolitan area, of whom 23 were currently homeless. The researcher assessed level of sleep disturbance, number of health problems and degree of homelessness using a standard demographic questionnaire, the General Health Questionnaire-12 (GHQ-12) and the Pittsburgh Sleep Quality Index (PSQI). Our results found evidence of significant sleep disturbance as well as significant mental and physical health problems in the sample. Correlational analyses provided partial support for the hypothesis that degree of homelessness impacts both sleep quality and physical health. Future work should investigate whether change in homelessness status alters sleep quality and physical health and also whether interventions may be utilized in this understudied and vulnerable population.

Drinking water-related exposures within populations living in the United States-Mexico border region, particularly among Hispanics, is an area that is largely unknown. Specifically, perceptions that may affect water source selection is an issue that has not been fully addressed. This study evaluates drinking water quality perceptions in a mostly Hispanic community living along the United States-Mexico border, a community also facing water scarcity issues. Using a survey that was administered during two seasons (winter and summer), data were collected from a total of 608 participants, of which 303 were living in the United States and 305 in Mexico. A (random) convenience sampling technique was used to select households and those interviewed were over 18 years of age. Statistically significant differences were observed involving country of residence (p=0.002). Specifically, those living in Mexico reported a higher use of bottled water than those living in the United States. Perception factors, especially taste, were cited as main reasons for not selecting unfiltered tap water as a primary drinking water source. Understanding what influences drinking water source preference can aid in the development of risk communication strategies regarding water quality. ^
