Assessment and Promotion of Partner Support: A Prevention-Focused Intervention for Perinatal Depression in Primary Care

Perinatal depression significantly impacts the mother, her partner, the unborn fetus, and the infant/child after delivery. A review of the literature supports the need for preventive intervention methods as research has shown that even with successful treatment, disruptions in attachment, temperament, and cognitive development often remain. Primary care settings are ideal targets for prevention given that they can reach a number of people at low-cost without the stigma associated with seeking help in a mental health facility. This paper purposes a preventive intervention method for perinatal depression that can be implemented in primary care settings in both Western and non-Western countries. The intervention targets two of the primary risk factors for perinatal depression; partner support and relationship quality. The intervention is structured around key target periods in gestational development and during the early weeks after delivery. Suggestions for each target visit are based on prior research that has demonstrated how psychoeducation about the transition to parenthood, as well as increased communication, can positively affect partner support and relationship quality. The ultimate goal of the intervention is not only to prevent perinatal depression but also to improve the mental health and wellbeing of the entire family system.

Mortalidad perinatal en los partos únicos asistidos a término en España entre 1995 y 2009 según ocurrieran en domicilio particular o en centro sanitario

Objetivo principal: Evidenciar posibles diferencias en la mortalidad perinatal de los partos únicos asistidos a término en España entre 1995 y 2009, según ocurrieran en domicilio particular o en centro sanitario. Metodología: Estudio de cohorte retrospectivo a partir del registro de partos del Instituto Nacional de Estadística de España (INE). Resultados principales: Entre 1995 y 2009 ocurrieron 23 muertes del feto o del recién nacido (hasta las primeras 24 horas de vida) sobre un total de 14.614 partos únicos asistidos a término en domicilio particular (1,57 muertes cada mil partos). El número de muertes en partos de las mismas características ocurridos en centros sanitarios fue de 7.548 sobre un total de 4.716.956 partos (1,60 muertes cada mil partos). OR=0,98 IC(95%)=0,65-1,48. Conclusión principal: Entre 1995 y 2009 no se han dado diferencias estadísticamente significativas en relación con la mortalidad del feto o el recién nacido registrada en el Boletín Estadístico del Parto, entre los partos únicos asistidos a término en domicilio particular y los partos de las mismas características atendidos en centro sanitario.

Muscle-Type Nicotinic Receptor Blockade by Diethylamine, the Hydrophilic Moiety of Lidocaine

Lidocaine bears in its structure both an aromatic ring and a terminal amine, which can be protonated at physiological pH, linked by an amide group. Since lidocaine causes multiple inhibitory actions on nicotinic acetylcholine receptors (nAChRs), this work was aimed to determine the inhibitory effects of diethylamine (DEA), a small molecule resembling the hydrophilic moiety of lidocaine, on Torpedo marmorata nAChRs microtransplanted to Xenopus oocytes. Similarly to lidocaine, DEA reversibly blocked acetylcholine-elicited currents (IACh) in a dose-dependent manner (IC50 close to 70 μM), but unlike lidocaine, DEA did not affect IACh desensitization. IACh inhibition by DEA was more pronounced at negative potentials, suggesting an open-channel blockade of nAChRs, although roughly 30% inhibition persisted at positive potentials, indicating additional binding sites outside the pore. DEA block of nAChRs in the resting state (closed channel) was confirmed by the enhanced IACh inhibition when pre-applying DEA before its co-application with ACh, as compared with solely DEA and ACh co-application. Virtual docking assays provide a plausible explanation to the experimental observations in terms of the involvement of different sets of drug binding sites. So, at the nAChR transmembrane (TM) domain, DEA and lidocaine shared binding sites within the channel pore, giving support to their open-channel blockade; besides, lidocaine, but not DEA, interacted with residues at cavities among the M1, M2, M3, and M4 segments of each subunit and also at intersubunit crevices. At the extracellular (EC) domain, DEA and lidocaine binding sites were broadly distributed, which aids to explain the closed channel blockade observed. Interestingly, some DEA clusters were located at the α-γ interphase of the EC domain, in a cavity near the orthosteric binding site pocket; by contrast, lidocaine contacted with all α-subunit loops conforming the ACh binding site, both in α-γ and α-δ and interphases, likely because of its larger size. Together, these results indicate that DEA mimics some, but not all, inhibitory actions of lidocaine on nAChRs and that even this small polar molecule acts by different mechanisms on this receptor. The presented results contribute to a better understanding of the structural determinants of nAChR modulation.

Androgen responsiveness to competition in humans: the role of cognitive variables

Although androgens are commonly seen as male sex hormones, it has been established over the years that in both sexes, androgens also respond to social challenges. To explain the socially driven changes in androgens, two theoretical models have been proposed: the biosocial model and the challenge hypothesis. These models are typically seen as partly overlapping; however, they generate different predictions that are clarified here. In humans, sports competition and nonmetabolic competitive tasks have been used in the laboratory setting, as a proxy for agonistic interactions in animals. The results reviewed here show that the testosterone (T) response to competition in humans is highly variable – the studies present postcompetition T levels and changes in T that depend on the contest outcome and that cannot be predicted by the current theoretical models. These conflicting results bring to the foreground the importance of considering cognitive factors that could moderate the androgen response to competition. Among these variables, we elect cognitive appraisal and its components as a key candidate modulating factor. It is known that T also modulates the cognitive processes that are relevant to performance in competition. In this article, we reviewed the evidence arising from studies investigating the effect of administering exogenous T and compare those results with the findings from studies that measured endogenous T levels. Finally, we summarized the importance of also considering the interaction between androgens and other hormones, such as cortisol, when investigating the social modulation of T, as proposed by the dual-hormone hypothesis.

Acidente vascular cerebral perinatal: 11 casos clínicos

Introdução: Os acidentes vasculares cerebrais (AVC) são causa de epilepsia e perturbações do neurodesenvolvimento. Têm tido uma incidencia crescente atribuível em parte à melhoria das tecnicas de imagens cerebrais. Alguns diagnósticos são efectuados retrospectivamente após o periodo neonatal. O objectivo da presente serie de casos clínicos foi identificar factores comuns que possam facilitar o diagnóstico no período neonatal. Material e métodos: Estudo retrospectivo efectuado com base na consulta dos processos clinicos dos recém-nascidos, com diagnóstico de AVC entre um de Janeiro de 2003 e 31 de Dezembro de 2013. Resultados: Foram identificados onze casos de AVC perinatal, num total 28382 nados-vivos. Dois casos foram diagnosticados no periodo fetal e nove no periodo neonatal. As convulsões foram a manifestação clinica mais frequente (8 em 11 casos). A mediana da idade de diagnóstico foi um dia e variou entre um e nove dias. A ecografia transfontanelar mostrou alterações em sete casos. A ressonancia magnetica nuclear cranio-encefalica mostrou alterações em todos os casos. Cinco AVC foram arteriais isquemicos, quatro hemorragicos e dois tromboses dos seios venosos. Em seis casos foram identificadas possiveis causas. Foram observadas complicações e sequelas em quatro dos casos. Discussão: As convulsões foram a manifestação clinica mais frequentemente encontrada.Em recém-nascidos de termo com convulsões sem historia de asfixia intraparto o AVC perinatal deverá ser diagnóstico de exclusão, mesmo na ausencia de alterações na ecografia transfontanelar.

Immunization with a circumsporozoite epitope fused to Bordetella pertussis adenylate cyclase in conjunction with cytotoxic T-lymphocyte-associated antigen 4 blockade confers protection against Plasmodium berghei liver-stage malaria

The adenylate cyclase toxoid (ACT) of Bordetella pertussis is capable of delivering its N-terminal catalytic domain into the cytosol of CD11b-expressing professional antigen-presenting cells such as myeloid dendritic cells. This allows delivery of CD8+ T-cell epitopes to the major histocompatibility complex (MHC) class I presentation pathway. Recombinant detoxified ACT containing an epitope of the Plasmodium berghei circumsporozoite protein (CSP), indeed, induced a specific CD8+ T-cell response in immunized mice after a single application, as detected by MHC multimer staining and gamma interferon (IFN-gamma) ELISPOT assay. This CSP-specific response could be significantly enhanced by prime-boost immunization with recombinant ACT in combination with anti-CTLA-4 during the boost immunization. This increased response was accompanied by complete protection in a number of mice after a challenge with P. berghei sporozoites. Transient blockade of CTLA-4 may overcome negative regulation and hence provide a strategy to enhance the efficacy of a vaccine by amplifying the number of responding T cells.
