Impact of parental cancer in offspring’s psychological development: literature review

O presente artigo engloba uma extensa revisão da literatura sobre a temática do câncer parental e as consequências pessoais e familiares desta vivência. Nesse sentido, são abordadas as principais consequências médicas e psicossociais do diagnóstico e tratamento do câncer e, usando o modelo sistémico, é descrita a influência (negativa e positiva) deste acontecimento no doente e noutros membros da família. É dado especial enfoque ao desenvolvimento psicológico dos filhos, incluindo os resultados dos estudos referentes ao stress traumático e crescimento pós-traumático, em particular no câncer da mama. São tecidas algumas implicações para a investigação nesta área, bem como sugestões para futuras investigações.The present paper includes an extended literature review about parental cancer and personal and family consequences of such experience. Some of the most important medical and psychosocial issues regarding the diagnosis and treatment of parental cancer are presented. Using a systemic theory as the background model it addresses the influences (negative and positive) of the event in the patient and in other family members. The present paper gives special focus on the offspring’s psychological development, including the results regarding traumatic stress and posttraumatic growth, particularly on breast cancer. Some implications and suggestions for future research are addressed.Fundação para a Ciência e a Tecnologia (FCT

Posttraumatic stress disorder symptoms and family functioning in adult children facing parental cancer: a comparison study

This study analyzed posttraumatic stress disorder (PTSD) symptoms and family functioning in a sample of adult children caregivers of cancer patients and in a group of adult children of nonchronically ill parents. Participants completed measures of family functioning and PTSD symptoms. The parental cancer group was subdivided into PTSD subgroups, and significant differences, on family functioning, were found. In the parental cancer group, the predictors of PTSD symptoms were being a woman and having an enmeshed or chaotic family functioning. Chaotic functioning mediated the relationship between family communication/satisfaction and PTSD symptoms, in the parental cancer group. Finally, there was a higher prevalence of PTSD symptoms in the parental cancer group, and participants with a probable PTSD diagnosis showed higher levels of family imbalance. This study shows that adult children facing parental cancer, who have a poorer family balance, may benefit from interventions that target family functioning.This research was supported by a grant (SFRH/BD/43275/2008) awarded to the first author (RJT) by the Portuguese Foundation for Science and Technology.info:eu-repo/semantics/publishedVersio

Comparison of chemical properties of food products processed by conventional and ohmic heating

The effect of ohmic and conventional heat processing of different food products on their chemical and physical parameters was studied. Depending on the food being analysed, parameters such as pH, total solids, ash, titratable acidity, ascorbic acid, total sugars, total fatty acids, total phenolic compounds, and anthocyanins content were determined before and after ohmic and conventional pasteurization techniques and the results were compared using one-way analysis of variance. In goat milk samples treated by ohmic technology the pH value (6.58) and total fatty acids content in milk fat (86.5 mass %) were comparable to those found in milk treated by conventional process, however, ohmically treated samples presented a lower content of lactic acid, 0.13 %. In cloudberry jam samples treated by ohmic technology the results of some of the main parameters tested, such as total sugar content 46.1 mass %, ascorbic acid content 2.83 mass %, and titratable acidity 6.01 mass % (as citric acid) did not show significant differences when compared with samples treated by conventional technology

A century and half of hydrogeomorphological disasters in Mainland Portugal

The disaster database lists disastrous floods and landslides registered in mainland Portugal in the period 1865–2015, based on data collected from newspapers. The database includes 1950 hydrogeomorphological disaster cases that caused 1256 deaths, 14,884 evacuated people and 41,977 displaced people. Disastrous floods are clustered in the Lisbon region and the Tagus valley, in the Oporto region and the Douro valley, in the Coimbra region and the Mondego valley and along the Vouga valley. Disastrous landslides are clustered in the Lisbon region and the Douro valley. The period 1935–1969 registered the highest number of disastrous floods and landslides, whereas the last 45 years of the series (1970–2015) do not show any clear temporal trend. However, the 10-year moving average increased at the beginning of the twenty-first century, for floods and landslides, and it is apparent the increasing number of disaster events consisting of several cases, which may result from the increasing occurrence of rainfall extreme events related with climate change. The spatial and temporal trends observed on disastrous floods and landslides reflect the distribution of conditioning factors, the temporal incidence of triggering factors, but also the evolution of the exposure and the vulnerability of people, structures and infrastructures.info:eu-repo/semantics/acceptedVersio

Thermal modification of activated carbon surface chemistry improves its capacity as redox mediator for azo dye reduction

The surface chemistry of a commercial AC (AC0) was selectively modified, without changing significantly its textural properties, by chemical oxidation with HNO3 (ACHNO3 ) and O2 (ACO2 ), and thermal treatments under H2 (ACH2) or N2 (ACN2 ) flow. The effect of modified AC on anaerobic chemical dye reduction was assayed with sulphide at different pH values 5, 7 and 9. Four dyes were tested: Acid Orange 7, Reactive Red 2, Mordant Yellow 10 and Direct Blue 71. Batch experiments with low amounts of AC (0.1 g L−1) demonstrated an increase of the first-order reduction rate constants, up to 9-fold, as compared with assays without AC. Optimum rates were obtained at pH 5 except for MY10, higher at pH 7. In general, rates increased with increasing the pH of point zero charge (pHpzc), following the trend ACHNO3 < ACO2 < AC0 < ACN2 < ACH2 . The highest reduction rate was obtained for MY10 with ACH2 at pH 7, which corresponded to the double, as compared with non-modified AC. In a biological system using granular biomass, ACH2 also duplicated and increase 4.5-fold the decolourisation rates of MY10 and RR2, respectively. In this last experiment, reaction rate was independent of AC concentration in the tested range 0.1–0.6 g L−1.This work was supported by the PTDC/AMB/69335/2006 project grants.

Moderate electric fields effects on whey protein´s structure, interactions and gelation

São Paulo School of Advanced Sciences on Reverse Engineering of Processed Foods[Excerpt] Proteins are important food constituents with a high nutritional and functional value. They are one of the food constituents most affected by heat, causing their unfolding, aggregation and gelation. Ohmic heating’s potential to improve the quality of foodstuffs have been demonstrated due to its uniform and fast heating, together with its presumed moderate electric field (MEF) related effects. The electric effects on foodstuffs, and particularly on proteins, are not yet fully disclosed and understood.
