Impact of the Covid-19 pandemic on perinatal mental health (Riseup-PPD-COVID-19): protocol for an international prospective cohort study
Background: Corona Virus Disease 19 (COVID-19) is a new pandemic, declared a public health emergency by the World Health Organization, which could have negative consequences for pregnant and postpartum women. The scarce evidence published to date suggests that perinatal mental health has deteriorated since the COVID-19 outbreak. However, the few studies published so far have some limitations, such as a cross-sectional design and the omission of important factors for the understanding of perinatal mental health, including governmental restriction measures and healthcare practices implemented at the maternity hospitals. Within the Riseup-PPD COST Action, a study is underway to assess the impact of COVID-19 in perinatal mental health. The primary objectives are to (1) evaluate changes in perinatal mental health outcomes; and (2) determine the risk and protective factors for perinatal mental health during the COVID-19 pandemic. Additionally, we will compare the results between the countries participating in the study.
Methods: This is an international prospective cohort study, with a baseline and three follow-up assessments over a six-month period. It is being carried out in 11 European countries (Albania, Bulgaria, Cyprus, France, Greece, Israel, Malta, Portugal, Spain, Turkey, and the United Kingdom), Argentina, Brazil and Chile. The sample consists of adult pregnant and postpartum women (with infants up to 6âmonths of age). The assessment includes measures on COVID-19 epidemiology and public health measures (Oxford COVID-19 Government Response Tracker dataset), Coronavirus Perinatal Experiences (COPE questionnaires), psychological distress (BSI-18), depression (EPDS), anxiety (GAD-7) and post-traumatic stress symptoms (PTSD checklist for DSM-V).
Discussion: This study will provide important information for understanding the impact of the COVID-19 pandemic on perinatal mental health and well-being, including the identification of potential risk and protective factors by implementing predictive models using machine learning techniques. The findings will help policymakers develop suitable guidelines and prevention strategies for perinatal mental health and contribute to designing tailored mental health interventions.

Azole assisted C-H bond activation promoted by an osmium-polyhydride: Discerning between N and NH
This is an open access article published under a Creative Commons Attribution (CC-BY)
License.The capacity of the hexahydride complex OsH6(PiPr3)2 (1) to discern between the nitrogen atom and the NH unit in the azole assisted aryl CâH bond activation
has been investigated. Complex 1 reacts with 2-phenylimidazole to give OsH3{Îș2-C,N-(C6H4-imidazole)}(PiPr3)2 (2), which has been characterized by X-ray diffraction analysis. The structure proves the higher affinity of the metal center for the N atom in the presence of the NH unit, which remains unchanged, and reveals that in the solid state the molecules of this complex form infinite chains by means of intermolecular asymmetric 3-center bifurcated dihydrogen bonds. In solution, 1HDOSY NMR experiments suggest that the association degree decreases as the temperature increases. The fused six-membered ring of benzimidazole weakens the NH bond, enhancing its reactivity. As a consequence, complex 1 cannot discern between the
N atom and the NH unit of 2-phenylbenzimidazole. Thus, the treatment of 1 with this substrate leads to a mixture of OsH3{Îș2-C,N-(C6H4-benzimidazole)}(PiPr3)2 (3) and the dinuclear species (PiPr3)2H3Os(C6H4-benzimidazolate)OsH(η2-H2)(PiPr3)2
(4). The latter is the result of a N-assisted ortho-CâH bond activation of the phenyl group promoted by 0.5 equiv of 1 and the NâH bond activation promoted by the remaining 0.5 equiv of hexahydride 1 along with the agostic coordination of the
remaining ortho-CâH bond to the metal center of the unsaturated fragment OsH(η 2-H2)(PiPr3)2. The comparison of the redox properties of 3 and 4 suggests that the interaction between the metal centers in the dinuclear compound is negligible. The
replacement of the NH group of the azoles by a sulfur atom does not modify the behavior of the substrates. Thus, the reactions of 1 with 2-phenylthiazole and 2-phenylbenzothiazole afford OsH3{Îș 2-C,N-(C6H4-thiazole)}(PiPr3)2 (5) and OsH3{Îș2-C,N-(C6H4-benzothiazole)}(PiPr3)2 (6). In turn, complexes 2, 3, 5, and 6 are phosphorescent.Financial support from the Spanish MINECO and FEDER (Projects CTQ2013-46459-C2-01-P to M.A.S., CTQ2014-52799-P to M.A.E., CTQ2013-44303-P to I.F., CTQ2014-54071-P to A.L., and CTQ2014-51912-REDC, the DGA (E35),

Toolkit per la valutazione delle abilitĂ sociali ed emotive a scuola
Il progetto âLearning to Be: Development of Practices and Methodologies for Assessing Social, Emotional and Health Skills within Education Systemsâ, cofinanziato dal programma Erasmus+ dellâUnione europea, Ăš un progetto sperimentale che coinvolge differenti Istituti ed Enti di ricerca che si occupano di istruzione ed educazione appartenenti a sette Paesi Europei: Finlandia, Italia, Lettonia, Lituania, Portogallo, Slovenia e Spagna. Il progetto, di durata triennale (febbraio 2017 - gennaio 2020), Ăš volto a sperimentare metodologie di insegnamento e strumenti per la valutazione delle competenze socio-emotive negli studenti a scuola, al fine di comprendere come queste abilitĂ possano essere supportate e promosse nei contesti educativi. âLearning to Beâ si basa sul principio che la valutazione a scuola possa andare oltre le pure conoscenze nozionistiche e la performance scolastica, includendo, al contrario, pratiche educative che permettano, in particolare, lâosservazione dello sviluppo personale e delle abilitĂ sociali e emotive. Pertanto, tale volume propone e descrive metodologie pratiche che possono essere utilizzate dai docenti e dagli studenti in classe al fine di sostenere gli aspetti sociali ed emotivi dellâapprendimento, promuovendo uno sviluppo sano della personalitĂ e incoraggiando la costruzione di relazioni positive a scuola. Questo Toolkit, pensato per i docenti di scuola primaria e secondaria di I grado, delinea i principi fondamentali per una pratica efficace dellâapprendimento socio-emotivo a scuola e fornisce tecniche pratiche per valutare le competenze socio-emotive degli studenti in classe, oltre che per facilitare e sostenere ulteriori apprendimenti. Pur non avendo lâobiettivo di fornire un quadro completo rispetto alle conoscenze e agli studi inerenti lâapprendimento socio-emotivo, ha altresĂŹ lo scopo di supportare i docenti nel migliorare le pratiche educative connesse alla valutazione a scuola. Crediamo che sia importante che tutti coloro che si occupano di educazione con bambini e giovani possano avere una formazione circa lo sviluppo emotivo e sociale, per comprendere in che modo questi aspetti impattino anche sullâapprendimento a scuola. Il titolo originale del progetto âLearning to Beâ (âimparare ad essereâ) Ăš un augurio affinchĂ© questo progetto sia di aiuto per gli studenti e per i docenti nel loro percorso di crescita, per âimparare ad essereâ felici e responsabili nei confronti degli altri
Selective meta-C-H bond activation of substituted 1,3-chlorobenzenes promoted by an osmium pyridyl complex
Ethylene displaces both the acetone and phosphine ligands of [OsTp{Îș1C-HNC5H3Me}(Îș1- OCMe2)(PiPr3)]BF4 (2; Tp = hydrydotris(pyrazolyl)borate). The reaction takes place by stages. Initially the replacement of acetone gives the mono(olefin) derivative [OsTp{Îș 1-C-[HNC5H3Me]}(η2-CH 2=CH2)(PiPr3)]BF4 (3). The substitution of the phosphine occurs at 120 °C and leads to the bis(olefin) complex [OsTp{Îș1-C[HNC5H 3Me]}(η2-CH2=CH2) 2]BF4 (4). The NH wingtip of 3 and 4 undergoes deprotonation with tert-butoxide to afford the corresponding pyridyl compounds [OsTp{Îș1-C[NC5H3Me]}(η2- CH2=CH2)(PiPr3)] (5) and [OsTp{Îș1-C[NC5H3Me]}(η2- CH2=CH2)2] (6). At 60 °C, the solvents chloro-3-fluorobenzene, 1,3-dichlorobenzene, and 3-chlorotoluene displace the pyridyl ligand of 6 to yield the haloaryl derivatives [OsTp(3,5-C 6H3ClX)(η2-CH2=CH 2)2] (X = F (7), Cl (8), Me (9)) as a result of the selective meta-C-H bond activation of the haloarenes. © 2014 American Chemical Society.Financial support from the Spanish MINECO (Projects CTQ2011-23459 and Consolider Ingenio 2010 (CSD2007-00006)), the DGA (E35), and the European Social Fund (FSE) is acknowledged.Peer Reviewe
Chelated Assisted Metal-Mediated NâH Bond Activation of ÎČâLactams: Preparation of Iridaâ, Rhodaâ, Osmaâ, and Ruthenatrinems
2-Azetidinones
substituted with pyridine (<b>2a</b>), quinoline
(<b>2b</b>), isoquinoline (<b>2c</b>), imidazole (<b>2d</b>), and benzimidazole (<b>2e</b>) at the 4-position
of the four-membered ring have been prepared in order to synthesize
tribactams containing a transition metal and its associated ligands,
L<sub><i>n</i></sub>M, at the 2-position of the tricyclic
skeleton. The developed procedure is compatible with a wide range
of transition-metal starting complexes. Thus, the iridium and rhodium
dimers [MÂ(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)ÂCl<sub>2</sub>]<sub>2</sub> react with <b>2a</b>â<b>e</b>, in
the presence of sodium acetate, to afford irida- and rhodatrinems
(<b>1a</b>â<b>j</b>) containing the half-sandwich
d<sup>6</sup> metal fragments MÂ(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)Cl (M = Ir, Rh). The reactions of [MÂ(ÎŒ-OMe)Â(η<sup>4</sup>-COD)]<sub>2</sub> (M = Ir, Rh) with <b>2a</b> lead
to irida- and rhodatrinems (<b>1k</b>,<b>l</b>) with the
d<sup>8</sup> moieties MÂ(η<sup>4</sup>-COD). The coordination
sphere and oxidation state of the metal center in these compounds
can be modified, without affecting the 2-azetidinone backbone, by
means of substitution and oxidative addition reactions. As a proof
of concept, metallatrinems with the MÂ(CO)<sub>2</sub> (M = Ir (<b>1m</b>), Rh (<b>1n</b>)) and IrÂ(Me)ÂIÂ(CO)<sub>2</sub> (<b>1o</b>) units are also reported. Osmatrinems <b>1p</b>,<b>q</b> containing the d<sup>4</sup> metal fragment OsH<sub>3</sub>(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> have been obtained starting
from the d<sup>2</sup> hexahydride OsH<sub>6</sub>(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub>, by reaction with <b>2a</b>,<b>b</b>, whereas the treatment of the tetrahydroborate complexes MHÂ(η<sup>2</sup>-H<sub>2</sub>BH<sub>2</sub>)Â(CO)Â(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> (M = Os, Ru) with <b>2a</b> yields osma- and
ruthenatrinems (<b>1r</b>,<b>s</b>) containing six-coordinate
bisÂ(phosphine) d<sup>6</sup> metal fragments. The IR stretching frequency
of the lactamic carbonyl, the bent angle between the five- and four-membered
rings of the tricycle, and the NâCO bond length in the lactamic
ring are clearly infuenced by the L<sub><i>n</i></sub>M
fragment
