Maternal representations during pregnancy and early motherhood

INFANT MENTAL HEALTH JOURNAL, Issue 1 2004
Ebru Taskin Ilicali
The aim of the present study was to study the maternal representations of pregnant women and mothers in their early postpartum period, by beginning the process of validating the maternal representations questionnaire L'entretien R1 and by developing a means to assess the content-free aspects of the representations. Participants were 23 primiparous (first-time mothers) pregnant women in their fourth to seventh month of pregnancy and 22 primiparous mothers in their early (zero to six months) postpartum period. It was found that the four subscales of L'entretien (self-as-mother, self-as-person, own-mother, and partner) produced meaningful results for Turkish subjects. The results were compatible with the idea of integrated representations of self-as-person and self-as-mother even in the second trimester of their pregnancy and also showed that they could differentiate themselves from their mothers as early as that period. The results revealed no significant differences in the content and content-free dimensions of the representations of pregnant women and mothers. ©2004 Michigan Association for Infant Mental Health.

Intravenous iron attenuates postvaccination anti-HBsAg titres after quadruple hepatitis B vaccination in dialysis patients with erythropoietin therapy

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2009
J.-H. Liu
Summary Background:, Anaemia in patients with end-stage renal disease (ESRD) is commonly treated with recombinant human erythropoietin (rHuEPO), often in combination with an adjuvant iron supplement. There is much evidence that rHuEPO can influence the immune response by its effect on lymphocytes. Also, iron catalyses the formation of radicals and increases the risk of major infections by negatively affecting the immune system. The relationship between antibodies to hepatitis B surface antigen (anti-HBsAg) responsiveness after hepatitis B vaccination and rHuEPO/adjuvant iron supplementation has not been reported before. Aim:, To determine the effects of subcutaneous erythropoietin and intravenous (i.v.) iron therapy on the responsiveness of anti-HBsAg after quadruple hepatitis B vaccination among ESRD patients. Methods:, Retrospective medical records were reviewed in a hospital with a tertiary teaching facility. Eighty-three ESRD patients, including 51 who underwent haemodialysis and 32 who underwent peritoneal dialysis therapy, received a quadruple recombinant hepatitis B vaccine. We investigated anti-HBsAg titres in those patients who either received rHuEPO alone (n = 50) or rHuEPO in combination with i.v. iron (n = 33). Results:, We found that the postvaccination anti-HBsAg titre was significantly lower in the rHuEPO plus i.v. iron group when compared with the group with rHuEPO alone (p < 0.05). The increment of anti-HBsAg between the initial month and the seventh month was positively correlated with therapeutic rHuEPO dosages in the group with rHuEPO alone (r = 0.303, p = 0.033). This relationship was not present in the rHuEPO with i.v. iron group (r = ,0.289, p = 0.229). Conclusions:, The levels of anti-HBsAg after hepatitis B vaccination are positively correlated with the dose of rHuEPO treatment during the vaccinated period among ESRD patients without i.v. iron supplementation. Also, i.v. iron negatively impacts the responsiveness of anti-HBsAg titre after hepatitis B vaccination in ESRD patients who have undergone rHuEPO therapy. [source]

Incidence and severity of marine borer attack at different depths at Mtongwe Jetty Pontoon Mombasa, Kenya

AFRICAN JOURNAL OF ECOLOGY, Issue 4 2009
P. K. Sirmah
Abstract The activity of marine borers was investigated at Mtongwe Jetty Pontoon, Mombasa, Kilindini harbour using untreated panels of Pinus patula (Schlecht) submerged to different depths. Twenty test panels replicated over 7 months were each strung in three ladder-like frames using nylon twine and suspended vertically, in such a way that the top most panels were 25 cm below the water surface at low and high tide. Monthly observations were made between January and July for the vertical incidence and extent of marine borer attack following the technique of Bobat (1995). Marine borers were collected from test panels, identified and counted. In addition, the percentage weight loss for panels at different depths was determined at the end of 7 months. Teredo fulleri (Clapp) was dominant on panels near water surface while Martesia striata (Linne) and Lyrodus pedicellatus (Quatrefages) were predominant at the bottom. The results showed that attack began within the first month of exposure and was severest by the seventh month. The vertical incidence and extent of attack decreased with increasing depth of panel exposure and was negatively correlated with depth. This is attributed to changes in hydrographic conditions. Résumé L'activité des foreurs marins a étéétudiée dans le Ponton de Mtongwe Jetty, Mombasa, dans le port de Kilindini, en utilisant des panneaux de Pinus patula (Schlecht) non traités, plongés à différentes profondeurs. Vingt panneaux tests identiques ont été attachés avec des cordes de nylon pour former trois cadres ressemblant à des échelles et suspendus pendant sept mois verticalement de façon à ce que les panneaux supérieurs se trouvent à 25 cm sous la surface à marée basse et haute. L'on a fait des observations mensuelles entre janvier et juillet de l'occurrence verticale et l'étendue de l'attaque des foreurs marins en utilisant la technique de Bobat (1995). Les foreurs marins ont été collectés sur les panneaux tests, identifiés et comptés. De plus, on a déterminé le pourcentage de la perte de poids des panneaux aux différentes profondeurs à la fin des sept mois. Teredo fulleri (Clapp) était dominant sur les panneaux situés près de la surface de l'eau alors que Martesia striata (Linné) et Lyrodus pedicellatus (Quatrefages) étaient prédominants en profondeur. Les résultats ont montré que l'attaque a commencé dès le premier mois et que c'est alors qu'elle fut la plus sévère. L'occurrence verticale et l'étendue de l'attaque diminuaient quand le panneau était plus profond et étaient négativement liées à la profondeur. Cela est attribué aux changements des conditions hydrographiques. [source]

The Potential Use of a Silicon Source as a Component of an Ecological Management of Coffee Plants

JOURNAL OF PHYTOPATHOLOGY, Issue 7-8 2008
J. C. Martinati
Abstract Coffee is one of the most important agricultural export commodities in the world and it represents the main export from some developing countries. Therefore, the development of new methods of coffee management that improves production without causing any damage to the environment is an attractive alternative for producers. Much effort has been invested towards understanding the mode of action of compounds that can induce resistance against several pathogens without injuring the environment. Many researches have considered silicon efficient in avoiding plant pathogen penetration and development. Our aim was to verify the effect of potassium silicate and calcium/magnesium silicate in the development of coffee seedlings (Coffea arabica cv. Mundo Novo) as well as to evaluate the incidence of coffee leaf rust development under greenhouse conditions. The experiment was a completely randomized design with 12 treatments with 10 plants per treatment. The treatments were 0, 0.25, 1.25, 2.5, 4 and 5 ,m of Si for each source of silicon incorporated into the soil. The seedlings were inoculated with a urediniospores suspension of Hemileia vastatrix (2 mg/ml) at the seventh month after planting (six pair of leaves). Evaluations were performed by counting the number of lesions per leaf. The statistical analysis showed that the number of lesions reduced by up to 66% at the highest silicon dose when compared to the number of lesions in control plants. Infected plants were found to have a linear decrease of lesions with the increase of silicate concentration. The lowest number of lesions per leaf area was observed in plants that received 5 ,m of Si from potassium silicate. This result indicates the use of silicon as an alternative for an ecological management system for coffee disease protection. [source]
