Prenatal and postnatal depression among low income Brazilian women

Postnatal depression is a significant problem affecting 10-15% of mothers in many countries and has been the subject of an increasing number of publications. Prenatal depression has been studied less. The aims of the present investigation were: 1) to obtain information on the prevalence of prenatal and postnatal depression in low income Brazilian women by using an instrument already employed in several countries, i.e., the Edinburgh Postnatal Depression Scale (EPDS); 2) to evaluate the risk factors involved in prenatal and postnatal depression in Brazil. The study groups included 33 pregnant women interviewed at home during the second and third trimesters of pregnancy, and once a month during the first six months after delivery. Questions on life events and the mother's relationship with the baby were posed during each visit. Depressed pregnant women received less support from their partners than non-depressed pregnant women (36.4 vs 72.2%, P<0.05; Fisher exact test). Black women predominated among pre- and postnatally depressed subjects. Postnatal depression was associated with lower parity (0.4 ± 0.5 vs 1.1 ± 1.0, P<0.05; Student t-test). Thus, the period of pregnancy may be susceptible to socio-environmental factors that induce depression, such as the lack of affective support from the partner. The prevalence rate of 12% observed for depression in the third month postpartum is comparable to that of studies from other countries.

Vanhempien psyykkinen hyvinvointi ja kiintymyksen kehittyminen keskosvauvaan Vanhemmat vahvasti mukaan -koulutusprojektin jälkeen

Tutkimuksen aiheena oli tutkia keskoslapsen vanhemman psyykkistä hyvinvointia ja kiintymyksen kehittymistä vauvaan keskosen sairaalahoidon aikana sekä kotiutumisen jälkeen. Tarkoituksena oli selvittää, oliko vanhempien välillä eroa masennuksen, tehohoitoympäristöstä aiheutuvan stressin ja kiintymyksen kehittymisessä keskoseen, ja muuttuivatko nämä ajan kuluessa. Lisäksi haluttiin selvittää liittyivätkö masennus, stressi ja kiintymys toisiinsa. Tutkimusaineisto koostui alle 34 raskausviikolla syntyneistä 55 keskosista ja heidän vanhemmistaan (48 äitiä ja 36 isää), jotka olivat osallistuneet Vanhemmat vahvasti mukaan (VVM) -evaluaatiotutkimukseen. Tutkimusaineistoa kerättiin kyselylomakkeilla kolmessa eri mittauspisteessä: 7±3 vuorokautta syntymästä, kotiutusajankohtana ja keskoslapsen korjatussa kuuden kuukauden iässä. Masennusta arvioitiin EPDS-mittarin (Edinburgh Postnatal Depression Scale) avulla kaikissa kolmessa aikapisteessä. Tehohoitoympäristöstä aiheutuvaa stressiä arvioitiin PSS:NICU-mittarilla (Parental Stressor Scale: Neonatal Intensive Care Unit) ja kiintymyksen kehittymistä keskosvauvaan BABY & YOU -mittarilla kahdessa ensimmäisessä mittauspisteessä. Vanhempien kokema masennus oli vähäistä, sillä keskoslapsen korjatussa kuuden kuukauden iässä 2,9 % äideistä oli masentuneita. Äidit kokivat isiin verrattuna enemmän masennusta, ja vanhempien masennus väheni syntymästä keskosen korjattuun kuuden kuukauden ikään. Vanhemmat kokivat tehohoitoympäristöstä aiheutuvan kokonaisstressin vähäisenä (äideillä ka=1,89 kh=0,52; isillä ka=1,56 kh=0,52). Äidit kokivat isiä enemmän stressiä syntymäaikapisteessä, ja äitien kokonaisstressi väheni keskosen kotiutusajankohtaan mennessä. Vanhempien kokonaisstressi tehohoitoympäristöstä korreloi hyvin vahvasti masennuksen kanssa kaikissa aikapisteissä, ja yksittäisenä eniten stressiä aiheuttavana tekijänä vanhemmat kokivat erossaolon vauvastaan. BABY & YOU -mittarilla arvioituna äidit kokivat isiä enemmän huolta ja eroahdistusta keskosvauvastaan. Syntymäaikapisteessä huoli keskosesta korreloi positiivisesti masennuksen kanssa. Äidit kokivat vähemmän masennusta, stressiä ja huolta keskosestaan, mikäli raskausaika oli ollut onnellinen. Vanhempien vähäinen masennus ja stressi voivat mahdollisesti liittyä VVM-koulutusprojektiin, jonka tavoitteena oli antaa vanhemmille vahva emotionaalinen tuki vauvansa hoitoon.

Fecal estradiol and progesterone metabolite levels in the three-toed sloth (Bradypus variegatus)

The present study was carried out to assess the possibility of measuring fecal steroid hormone metabolites as a noninvasive technique for monitoring reproductive function in the three-toed sloth, Bradypus variegatus. Levels of the estradiol (E2) and progesterone (P4) metabolites were measured by radioimmunoassay in fecal samples collected over 12 weeks from 4 captive female B. variegatus sloths. The validation of the radioimmunoassay for evaluation of fecal steroid metabolites was carried out by collecting 10 blood samples on the same day as defecation. There was a significant direct correlation between the plasma and fecal E2 and P4 levels (P < 0.05, Pearson's test), thereby validating this noninvasive technique for the study of the estrous cycle in these animals. Ovulation was detected in two sloths (SL03 and SL04) whose E2 levels reached 2237.43 and 6713.26 pg/g wet feces weight, respectively, for over four weeks, followed by an increase in P4 metabolites reaching 33.54 and 3242.68 ng/g wet feces weight, respectively. Interestingly, SL04, which presented higher levels of E2 and P4 metabolites, later gave birth to a healthy baby sloth. The results obtained indicate that this is a reliable technique for recording gonadal steroid secretion and thereby reproduction in sloths.

The effect of epidural and general anesthesia on newborn rectal temperature at elective cesarean section

Both epidural and general anesthesia can impair thermoregulatory mechanisms during surgery. However, there is lack of information about the effects of different methods of anesthesia on newborn temperature. The purpose of this study was to determine whether there are differences in newborn rectal temperature related to type of anesthesia. Sixty-three pregnant women were randomly assigned to receive general or epidural anesthesia. Maternal core temperature was measured three times with a rectal probe just before anesthesia, at the beginning of surgery and at delivery. In addition, umbilical vein blood was sampled for pH. The rectal temperatures of the babies were recorded immediately after delivery, and Apgar scores were determined 1, 5, and 10 min after birth. The duration of anesthesia and the volume of intravenous fluid given during the procedure (833 ± 144 vs 420 ± 215 mL) were significantly higher in the epidural group than in the general anesthesia group (P < 0.0001). Maternal rectal temperatures were not different in both groups at all measurements. In contrast, newborn rectal temperatures were lower in the epidural anesthesia group than in the general anesthesia group (37.4 ± 0.3 vs 37.6 ± 0.3°C; P < 0.05) immediately after birth. Furthermore, the umbilical vein pH value (7.31 ± 0.05 vs 7.33 ± 0.01; P < 0.05) and Apgar scores at the 1st-min measurement (8.0 ± 0.9 vs 8.5 ± 0.7; P < 0.05) were lower in the epidural anesthesia group than in the general anesthesia group. Since epidural anesthesia requires more iv fluid infusion and a longer time for cesarean section, it involves a risk of a mild temperature reduction for the baby which, however, did not reach the limits of hypothermia.

Taxa de respiração de cenouras minimamente processadas e armazenadas em diferentes temperaturas

Entre as hortaliças minimamente processadas, a cenoura é uma das mais populares, sendo comercializada de várias maneiras: raladas, cortadas em fatias, palitos, e ainda apresentadas na forma de mini-cenoura (baby carrot). O objetivo deste estudo foi determinar as taxas respiratórias de cenouras (Daucus carota) da cultivar Nantes minimamente processadas. O armazenamento foi realizado nas temperaturas de 1 °C, 5 °C e 11 °C, e 90% UR. A taxa respiratória foi determinada usando um fluxo contínuo de ar. O teor de CO2 e etileno foi medido por um cromatógrafo a gás. A taxa de respiração para as cenouras fatiadas foi mais alta do que para os produtos inteiros. Os valores da energia de ativação obtidos para as cenouras fatiadas e inteiras foi de 69,82 kJmol-1 e 54,60 kJmol-1, respectivamente. A produção de etileno foi insignificante para as cenouras durante os 14 dias de armazenamento.

St. Catharines and District Council of Women fonds

The St. Catharines and District Council of Women was founded in 1918 and elected as its first president, Mary Malcolmson. In 1910 Mrs. Malcolmson founded North America’s first Girl Guide Association in St. Catharines. The aim of the organization was to work for the betterment of conditions pertaining to the family, community and state. The Council is an umbrella group for various women’s organizations in the area and functions at the provincial, national and international levels and is associated with the United Nations. In the early years the National Council brought in the Victorian Order of Nurses (VON) and started the Women’s Canadian Club. The St. Catharines Council initiated Child Welfare Centres in local churches that grew into the Well Baby Clinics. Women were encouraged to take political office and join committees with much success. In 1929, “Shop at Home” exhibition became an annual event highlighting the services of local merchants. Money raised by the Council was donated to local charities and in 1930 the Council assisted the local Armenian community in building the first Armenian Church in Canada. In 1932 the Council started the Maternal Welfare programme in which Mothers’ Meetings were held weekly with various speakers from the Public Health Department. In 1975 to celebrate International Women’s Year and the 1976 Centennial of the City of St. Catharines, the group sponsored the book Women of Action, 1876-1976, written by two of its members, Lily M. Bell and Kathleen E. Bray. Some time after 1976 the name of the organization changed from St. Catharines Local Council of Women to St. Catharines and District Council of Women. Today the organization functions as an advocacy and educational group.

The role of intrapartum intravenous therapy and method of delivery on newborn weight loss : challenging the 7% rule

It is common practice to initiate supplemental feeding in newborns if body weight decreases by 7-10% in the first few days after birth (7-10% rule). Standard hospital procedure is to initiate intravenous therapy once a woman is admitted to give birth. However, little is known about the relationship between intrapartum intravenous therapy and the amount of weight loss in the newborn. The present research was undertaken in order to determine what factors contribute to weight loss in a newborn, and to examine the relationship between the practice of intravenous intrapartum therapy and the extent of weight loss post-birth. Using a cross-sectional design with a systematic random sample of 100 mother-baby dyads, we examined properties of delivery that have the potential to impact weight loss in the newborn, including method of delivery, parity, duration of labour, volume of intravenous therapy, feeding method, and birth attendant. This study indicated that the volume of intravenous therapy and method of delivery are significant predictors of weight loss in the newborn (R2=15.5, p<0.01). ROC curve analysis identified an intravenous volume cut-point of 1225 ml that would elicit a high measure of sensitivity (91.3%), and demonstrated significant Kappa agreement (p<0.01) with excess newborn weight loss. It was concluded that infusion of intravenous therapy and natural birth delivery are discriminant factors that influence excess weight loss in newborn infants. Acknowledgement of these factors should be considered in clinical practice.

Supporting fathering through infant massage

Developing a strong relationship is essential for optimal child development and it is possible for fathers to fully participate in developing this close bond. Men often develop this relationship through interactive play which usually occurs later in their child's development. As a result, fathers often feel dissatisfied with their ability to form a close attachment in the early post-partum period, which in turn may increase their stress level. However, men can be prepared for the transition to fatherhood if they develop the knowledge and skill necessary to create positive relationships with their infants. Infant massage appears to be a viable option for teaching fathers care-giving sensitivity. To build on the notion of teaching fathers attachment system behaviour in early infancy, a quasi-experimental, mixed methods study was employed. Twenty-four infant-father dyads were recruited for the study. The fathers were asked to fill out the Parent Stress Index and a facial cues rating scale at two times, one month apart. The experimental group also participated in an infant massage intervention taught by a Certified Infant Massage Instructor of the International Association of Infant Massage. A repeated measures MANOVA revealed infant massage decreased paternal stress. Qualitatively, the fathers provided rich descriptions of their experience in the baby massage class which provided useful insight into the efficacy of the intervention. Overall, the fathers enjoyed the experience but did not necessarily see the direct benefit of the intervention on their relationship. Recommendations for pre and postnatal education for fathers are made.

Innovation, artistes et managers, ethnographie du Cirque du Soleil

Considérant que le Canada aura perdu presque un million de travailleurs qualifiés en 2020 et qu’en 2005, déjà 40 à 60% des travailleurs de la génération des baby-boomers ont pris leur retraite, on peut anticiper que les capacités d’innovation des entreprises sont en train de devenir un enjeu de société. De plus, depuis quelques années déjà, on remarque que la valeur des connaissances et de la créativité au sein des économies capitalistes a augmenté, plaçant les industries créatives au premier plan. En fait, les activités de création artistique incarneraient l’expression la plus avancée des modes de production et des relations au sein du monde du travail engendrées par les mutations récentes du capitalisme. Apprendre à innover devient dès lors une priorité et, comme les pratiques exemplaires émergent généralement chez les leaders d’une industrie, le cirque le plus applaudi à travers le monde, le Cirque du Soleil, représente un terrain idéal de renouvellement des pratiques d’innovation. Centrée spécifiquement sur le cas de l’innovation artistique, cette recherche explore les interactions entre les artistes et les managers pendant les premières phases d’un projet d’architecture menant à la construction d’un centre d’art et de divertissement, un des secteurs d’affaires de l’entreprise. Cette thèse présente les résultats d’une étude de cas effectuée dans un champ de recherche en émergence au sein des recherches en management : le croisement entre l’art et le management. À partir d’une perspective interdisciplinaire incluant une méthodologie ethnographique et une approche esthétique des organisations, l’étude met l’accent sur la co-création de connaissances parmi les artistes et les managers participant à un projet de grande envergure. La problématique de l’innovation est étudiée par le biais des pratiques managériales et artistiques, à partir de l’étude des organisations, de l’anthropologie et de la sociologie. L’étude vise à comprendre comment ces deux groupes culturels distincts travaillent et apprennent dans l’action et comment leurs pratiques collectives sont créées, partagées et mises en œuvre. À partir du quotidien de 26 artistes et managers suivi sur une période de 9 mois, complété par l’analyse de plus de 5500 pages de documents et de 20 heures de vidéo, une ethnographie de type récit de fiction donne accès à la culture de ces maîtres bâtisseurs, à leur imaginaire, à leur mode de vie et à leurs pratiques. La cognition partagée entre ces acteurs de l’industrie créative des arts du cirque donne lieu à sept pratiques (tribu, dialogue, récits, innovation, action, rapports et mémoire) qui sont décrites selon une double perspective, le management et les sciencs humaines. Outre une méthodologie qui intègre l’approche esthétique des organisations, une nouvelle définition de la face cachée de l’innovation est proposée, ainsi qu’un modèle conceptuel dynamique développé à partir des pratiques novatrices du Cirque du Soleil. Créatives, celles-ci constituent une source d’inspiration pour le domaine du management. En ce sens, cette recherche contribue à l’étude des organisations et au développement de pratiques créatives de management.

Lecture sociodémographique de l'évolution de la mortalité par suicide au Québec (1926-2004): la question de l'âge et des générations.

Depuis deux siècles, les transformations les plus remarquables du phénomène du suicide concernent la relation avec la variable âge. En effet, le suicide a longtemps progressé avec l'âge pour culminer à la vieillesse, mais le dernier quart de siècle au Québec a vu ce rapport modifié, suggérant qu'il s'agit désormais d'un phénomène de jeunes. Notre étude examine les tendances récentes de l'évolution de la mortalité par suicide au Québec du point de vue de l'âge, discute des effets respectifs possibles de l'âge, de la période et de la génération de 1926 à 2004 et offre des pistes d'interprétation sociologique. Nous présentons dans un premier temps les transformations de la société québécoise depuis 1930 ainsi qu'un bilan synthétique des connaissances sur le suicide au Québec par rapport aux tendances internationales, ceci du point de vue de différentes variables sociodémographiques. Notre étude rappelle ensuite les grandes théories et idées sur le suicide, de la littérature classique aux réflexions contemporaines. On y remarque que la variable âge est rarement au coeur de ces conceptions, mais plutôt en marge de celles-ci, médiatisées par d'autres variables sociales. Les résultats de notre analyse montrent la présence d'un net effet de génération dans l'évolution de la mortalité masculine due au suicide au Québec. Ce phénomène n'est pas présent chez les femmes. Les générations récentes adoptent toutefois un comportement différent de celles des baby-boomers et il sera intéressant de suivre leur trajectoire dans l'avenir.
