Grandparenthood, grandchild care and depression among older people in 18 countries

Due to the increasing central role of grandparenthood in later life, sound knowledge about its effects on older people’s health is more and more important. This paper examines the impact of becoming a grandparent, having more grandchildren, and engaging in grandchild care on depressive symptoms. Moreover, based on the structural ambivalence theory, we expect that such effects differ across contexts as (grand)childcare is differently organised across Europe. Taking advantage of the longitudinal structure of the Survey of Health, Ageing and Retirement in Europe (SHARE), we estimate fixed-effects models. Our results show that women face a decline in depressive symptoms when becoming grandmothers, but neither an increase in the number of grandchildren nor changes in grandchild care are associated with changes in depressive symptoms. The analyses by country highlight differences across Europe, without, however, drawing a clear pattern. Our results show that depression consequences of grandparenthood also vary between countries characterised by similar roles of grandparents. This suggests the need to make available more refined questions about grandparenthood in surveys on older people.Aufgrund der zunehmend zentralen Rolle von Großelternschaft im späteren Leben wird fundiertes Wissen zu deren Auswirkungen auf die Gesundheit älterer Menschen immer wichtiger. Dieses Papier untersucht die Auswirkungen des Übergangs in die Großelternschaft der Geburt weiterer Enkelkinder sowie des Engagements in der Enkelkinderbetreuung auf depressive Symptome. Überdies erwarten wir auf der Grundlage der Theorie der strukturellen Ambivalenz, dass sich die Stärke dieser Effekte zwischen verschiedenen Kontexten unterscheidet, da die (Enkel-)Kinderbetreuung innerhalb Europas unterschiedlich organisiert ist. Unter Nutzung der Längsschnittstruktur des Survey of Health, Ageing and Retirement in Europe (SHARE) schätzen wir Fixed-Effects-Modelle. Unsere Ergebnisse zeigen, dass Frauen einen Rückgang der depressiven Symptome erleben, wenn sie erstmals Großmütter werden, aber weder eine Erhöhung der Anzahl der Enkelkinder noch Veränderungen in der Enkelkinderbetreuung sind mit Veränderungen der depressiven Symptomatik verbunden. Die Analysen nach Ländern zeigen Unterschiede innerhalb Europas auf, ohne dass jedoch ein klares Muster zu erkennen ist. Unsere Ergebnisse zeigen, dass die depressionsbezogenen Folgen einer Großelternschaft auch zwischen Ländern variieren, in denen die Rollen der Großeltern ähnlich geprägt sind. Dies legt nahe, dass in Umfragen unter älteren Menschen die Fragen zur Großelternschaft weiterentwickelt werden müssen

Magnetic Reconnection Driven by Thermal and Non-thermal Particle Energy Densities

Magnetic reconnection is usually associated with conversion of magnetic energy into particle acceleration or thermal energy. However, a specific reconnection process driven by plasma pressure gradients was identified in Ref. [1] with a consistent theory of (non-ideal) MHD m0=1 modes in well confined plasmas. This process, based on an Ohm's law contribution to the electron balance equations, remains the basis for the explanation of the observed sawtooth oscillations of the central plasma pressure and for the inferred magnetic field structures due to fishbone oscillations [2] associated with injected high energy particle populations. A novel process [3] expected to have a wide range of applications concerns magnetic reconnection sustained by a significant gradient of the longitudinal electron temperature and based on the electron thermal energy balance equation rather than on an Ohm's law. A comparison is made with the Biermann Battery concept considering that the growth of reconnection depends on the particle density gradient in addition to that (aligned with it) of the electron temperature

COVID-19 precautionary behaviors and vaccine acceptance among older individuals: The role of close kin

The family plays a central role in shaping health behaviors of its members through social control and support mechanisms. We investigate whether and to what extent close kin (i.e., partner and children) matter for older people in taking on precautionary behaviors (e.g., wearing a mask) and vaccination during the COVID-19 pandemic in Europe. Drawing on data from the Survey of Health, Ageing and Retirement in Europe (SHARE), we combine its Corona Surveys (June to September 2020 and June to August 2021) with pre-COVID information (October 2019 to March 2020). We find that having close kin (especially a partner) is associated with a higher probability of both adopting precautionary behaviors and accepting a COVID-19 vaccine. Results are robust to controlling for other potential drivers of precautionary behaviors and vaccine acceptance and to accounting for coresidence with kin. Our findings suggest that policymakers and practitioners may differently address kinless individuals when promoting public policy measures

Changes in Grandparental Childcare During the Pandemic and Mental Health: Evidence From England

OBJECTIVES: Policies aiming at reducing rates of hospitalization and death from coronavirus disease 2019 (COVID-19) encouraged older people to reduce physical interactions. In England, until July 2021, provision of care for grandchildren was allowed only under very limited circumstances. Evidence also suggests that reduced face-to-face interactions took a toll on mental health during the pandemic. This study aims to investigate associations between changes in grandchild care provision during the first 8/9 months of the pandemic and grandparents' mental health. METHODS: Using prepandemic data from Wave 9 (2018/2019) and the second COVID-19 substudy (November/December 2020) of the English Longitudinal Study of Ageing, we first describe changes in grandchild care provision during the pandemic to then investigate, using regression models, associations between changes in grandchild care provision and mental health (depression, quality of life, life satisfaction), while controlling for prepandemic levels of the outcome variables. RESULTS: About 10% of grandparents stopped looking after grandchildren altogether during the first 9 months of the pandemic, with 22% reporting an overall decrease in the amount of grandchild care provided. Compared to grandparents who mostly maintained unchanged their grandchild care provision, those who stopped altogether and those who mostly reduced the amount of grandchild care provided were more likely to report poorer mental health, even accounting for prepandemic health. DISCUSSION: While measures to limit physical contact and shield older people were necessary to reduce the spread of COVID-19, policymakers should acknowledge potential adverse consequences for mental health among grandparents who experienced changes in their roles as grandchild caregivers

Localizzazione e internazionalizzazione dei servizi di incrocio domanda/offerta di lavoro di Jopla S.r.l SB: tra traduzione umana e traduzione automatica

This thesis has been written as a result of the Language Toolkit project, organised by the Department of Interpreting and Translation of Forlì in collaboration with the Chamber of Commerce of Romagna. The aim of the project is to facilitate the internationalisation of small and medium enterprises in Romagna by making available to them the skills acquired by the students of the Faculty of Specialized Translation, who in turn are given the opportunity to approach an authentic professional context. Specifically, this thesis is the outcome of the 300-hour internship envisaged by the project, 75 of which were carried out at Jopla S.r.l. SB. The task assigned to the student was the translation into French of the Jopla For You web app and the Jopla PRO mobile app. This thesis consists of five chapters. The first chapter provides a general description of the Language Toolkit project and it focuses on the concept of translation into a non-native language. The second chapter outlines the theoretical context in which translation is set. Subsequently, the focus shifts to the topics of text, discourse, genre and textual typology, alongside a reflection on the applicability of these notions to web texts, and an analysis of the source text following Nord's model. The fourth chapter is dedicated to a description of the resources used in the preparation and translation phases. The fifth chapter describes the macro and micro strategies employed to carry out the translation. Furthermore, a comparative analysis between the human translation and the one provided by Google Translator is delivered. This analysis involves two methods: the first one follows the linguistic norms of the target language, while the second one relies on the error categorisation of the MQM model. Finally, the performance of Google Translate is investigated through the comparison of the results obtained from the MQM evaluation conducted in this thesis with the results obtained by Martellini (2021) in her analysis

Tools for the development of a benthic quality index for Italian lakes

In this paper, we propose a methodology to develop a benthic quality index useful for Italian lakes. The existing data about benthic macroinvertebrates of the Italian lakes were collected over a period of 50 years, but only a few lakes such as the Maggiore and the Mergozzo have been intensely studied. Some large lakes such as Lake Como are still almost uninvestigated. In total, 570 benthic macroinvertebrate taxa were identified; of which 373 belong to Chironomidae and 85 to Oligochaeta. With the aim of relating environmental variables with macrobenthos assemblages, we carried out a canonical correlation analysis (CANON) using a database that included 1060 sampling points. Both environmental (13 variables describing morphometry and hydrochemistry) and biological data (57 taxa) were available, but only taxa present in at least 10 samples were selected for data analysis. Three canonical variates were ecologically significant. The first one was correlated with conductivity, pH and alkalinity and accounted for 20% of the total variation. The second one was positively correlated with total phosphorus and N-NH4, and inversely with dissolved oxygen, and accounted for 18% of the total variation. The third one showed a direct correlation with maximum lake depth and volume and an inverse correlation with water temperature, and accounted for 17% of the total variation. A Trophic Status Index (TSI), based on the table 11 of the Italian Law 152/99 (without including chlorophyll), was calculated by ranking percent oxygen saturation, transparency and total phosphorus. TSI was used to test a Benthic Quality Index for Italian Lakes (BQIL) which is proposed in the present paper. The algorithm considered three steps. First, the means of three variables were calculated: percent oxygen saturation, transparency and total phosphorus weighted by the taxa abundances. These values are interpreted as optimum for each taxon and used to assign an indicator weight (BQIW). Second, the mean of these three variables was calculated for each taxon (mean BQIW). Third, the mean BQIW was multiplied by taxa abundance and divided by the total number of specimens present at each site for which the BQIL was obtained. Using a regression between BQIL and TSI values, lake sites were assigned to 5 quality classes as required by the Italian Law 152/99 and the WFD 2000/60/CE. This assignment must be considered as tentative, because different lake types should be considered separately to develop an index. At present the lack of information from different lake typologies hinders the development of a more sophisticated index such as the French Lake Biotic Index (LBI).Studio iniziale per la messa a punto di una metrica (indice di qualit?) delle acque dei laghi Italiani con l\u27utilizzo del macrobenthos per l\u27assegnazione dei suddetti laghi a 5 categorie di qualit?, cos? come previsto dalla Direttiva Quadro sulle Acque (WFD 2000/60/CE).

Oxidation effects in antiaggregogenic properties of Epigallocatechingallate

Epigallocatechin-gallate (EGCG), the most abundant flavonoid in green tea, has been extensively studied for its potential in the treatment of amyloid related disorders. This molecule was found to modulate abnormal protein self-assembly, reducing resulting cellular toxicity. EGCG is known to suppress or to slow down the aggregation processes of several proteins, thus supporting the idea that general mechanisms regulate its anti-aggregogenic effects and, interestingly, in the oxidised form it demonstrated an higher efficiency in reducing protein aggregation with respect to intact molecule. We here investigate the effects of intact and oxidized EGCG the thermal aggregation pathway of Bovine Serum Albumin (BSA), a well-known model protein whose aggregation processes are known in details. By means of different spectroscopic methods, we evaluate similarities and differences of the two molecules during protein aggregation. Different solution conditions are investigated, close and away from the isoelectric point of the protein, with the aim of eliciting the role of electrostatics in the observed EGCG-Protein interaction and in the supramolecular assembly which are dramatically dependent on solution conditions

The Oxidative state of LDL is the major determinant of anti/prooxidant effect of coffee on Cu²⁺ catalysed peroxidation

Antioxidants exert contrasting effect on low density lipoprotein (LDL) oxidation catalysed by metals, acting as pro-oxidants under select in vitro conditions. Through our study on the effect of coffee on LDL oxidation, we identified the parameters governing this phenomenon, contributing to the comprehension of its mechanism and discovering significant implications for correct alimentary recommendations. By measuring conjugated diene formation, we have analysed the quantitative and qualitative effects exerted by an extract of roasted coffee on LDL oxidation triggered by copper sulphate. When the relative effects of different coffee concentrations were plotted against the lag time (LT) of control LDL (C-LDL), the apparently random experimental data arranged in sensible patterns: by increasing the LT the antioxidant activity of coffee decreased progressively to become prooxidant. The critical LT, at which coffee switches from antioxidant to prooxidant, increased by increasing coffee concentration. Also the contrasting results obtained following a delayed addition of coffee to the assay, arranged in a simple pattern when referred to the LT of C-LDL: the prooxidant effect decreased to become antioxidant as the LT of C-LDL increased. The dependence of coffee effect on the LT of C-LDL was influenced by LDL but not by metal catalyst concentration. These novel findings point to the oxidative state of LDL as a major parameter controlling the anti/prooxidant effect of coffee and suggest the LT of C-LDL as a potent analytical tool to express experimental data when studying the action exerted by a compound on LDL oxidation

Analgesia induced by the epigenetic drug, L-acetylcarnitine, outlasts the end of treatment in mouse models of chronic inflammatory and neuropathic pain

Background: L-acetylcarnitine, a drug marketed for the treatment of chronic pain, causes analgesia by epigenetically up-regulating type-2 metabotropic glutamate (mGlu2) receptors in the spinal cord. Because the epigenetic mechanisms are typically long-lasting, we hypothesized that analgesia could outlast the duration of L-acetylcarnitine treatment in models of inflammatory and neuropathic pain. Results: A seven-day treatment with L-acetylcarnitine ( 100 mg/kg, once a day, i.p.) produced an antiallodynic effect in the complete Freund adjuvant mouse model of chronic inflammatory pain. L-Acetylcarnitine-induced analgesia persisted for at least 14 days after drug withdrawal. In contrast, the analgesic effect of pregabalin, amitryptiline, ceftriaxone, and N-acetylcysteine disappeared seven days after drug withdrawal. L-acetylcarnitine treatment enhanced mGlu2/3 receptor protein levels in the dorsal region of the spinal cord. This effect also persisted for two weeks after drug withdrawal and was associated with increased levels of acetylated histone H3 bound to the Grm2 gene promoter in the dorsal root ganglia. A long-lasting analgesic effect of L-acetylcarnitine was also observed in mice subjected to chronic constriction injury of the sciatic nerve. In these animals, a 14-day treatment with pregabalin, amitryptiline, tramadol, or L-acetylcarnitine produced a significant antiallodynic effect, with pregabalin displaying the greatest efficacy. In mice treated with pregabalin, tramadol or L-acetylcarnitine the analgesic effect was still visible 15 days after the end of drug treatment. However, only in mice treated with L-acetylcarnitine analgesia persisted 37 days after drug withdrawal. This effect was associated with an increase in mGlu2/3 receptor protein levels in the dorsal horns of the spinal cord. Conclusions: Our findings suggest that L-acetylcarnitine has the unique property to cause a long-lasting analgesic effect that might reduce relapses in patients suffering from chronic pain
