Comparative complete scheme and booster effectiveness of COVID-19 vaccines in preventing SARS-CoV-2 infections with SARS-CoV-2 Omicron (BA.1) and Delta (B.1.617.2) variants: A case-case study based on electronic health records.

Background: Information on vaccine effectiveness in a context of novel variants of concern (VOC) emergence is of key importance to inform public health policies. This study aimed to estimate a measure of comparative vaccine effectiveness between Omicron (BA.1) and Delta (B.1.617.2 and sub-lineages) VOC according to vaccination exposure (primary or booster). Methods: We developed a case-case study using data on RT-PCR SARS-CoV-2-positive cases notified in Portugal during Weeks 49-51, 2021. To obtain measure of comparative vaccine effectiveness, we compared the odds of vaccination in Omicron cases versus Delta using logistic regression adjusted for age group, sex, region, week of diagnosis, and laboratory of origin. Results: Higher odds of vaccination were observed in cases infected by Omicron VOC compared with Delta VOC cases for both complete primary vaccination (odds ratio [OR] = 2.1; 95% confidence interval [CI]: 1.8 to 2.4) and booster dose (OR = 5.2; 95% CI: 3.1 to 8.8), equivalent to reduction of vaccine effectiveness from 44.7% and 92.8%, observed against infection with Delta, to -6.0% (95% CI: 29.2% to 12.7%) and 62.7% (95% CI: 35.7% to 77.9%), observed against infection with Omicron, for complete primary vaccination and booster dose, respectively. Conclusion: Consistent reduction in vaccine-induced protection against infection with Omicron was observed. Complete primary vaccination may not be protective against SARS-CoV-2 infection in regions where Omicron variant is dominant.

Comparative Effectiveness of COVID-19 Vaccines in Preventing Infections and Disease Progression from SARS-CoV-2 Omicron BA.5 and BA.2, Portugal.

We estimated comparative primary and booster vaccine effectiveness (VE) of SARS-CoV-2 Omicron BA.5 and BA.2 lineages against infection and disease progression. During April-June 2022, we implemented a case-case and cohort study and classified lineages using whole-genome sequencing or spike gene target failure. For the case-case study, we estimated the adjusted odds ratios (aORs) of vaccination using a logistic regression. For the cohort study, we estimated VE against disease progression using a penalized logistic regression. We observed no reduced VE for primary (aOR 1.07 [95% CI 0.93-1.23]) or booster (aOR 0.96 [95% CI 0.84-1.09]) vaccination against BA.5 infection. Among BA.5 case-patients, booster VE against progression to hospitalization was lower than that among BA.2 case-patients (VE 77% [95% CI 49%-90%] vs. VE 93% [95% CI 86%-97%]). Although booster vaccination is less effective against BA.5 than against BA.2, it offers substantial protection against progression from BA.5 infection to severe disease.

Rapid waning of protection induced by prior BA.1/BA.2 infection against BA.5 infection.

SARS-CoV-2 omicron subvariants BA.1 and BA.2 became dominant in many countries in early 2022. These subvariants are now being displaced by BA.4 and BA.5. While natural infection with BA.1/BA.2 provides some protection against BA.4/BA.5 infection, the duration of this protection remains unknown. We used the national Portuguese COVID-19 registry to investigate the waning of protective immunity conferred by prior BA.1/BA.2 infection towards BA.5. We divided the individuals infected during the period of BA.1/BA.2 dominance (>90% of sample isolates) in successive 15-day intervals and determined the risk of subsequent infection with BA.5 over a fixed period. Compared with uninfected people, one previous infection conferred substantial protection against BA.5 re-infection at 3 months (RR=0.12; 95% CI: 0.11-0.12). However, although still significant, the protection was reduced by two-fold at 5 months post-infection (RR=0.24; 0.23-0.24). These results should be interpreted in the context of vaccine breakthrough infections, as the vaccination coverage in the individuals included in the analyses is >98% since the end of 2021. This waning of protection following BA.1/BA.2 infection highlights the need to assess the stability and durability of immune protection induced with the adapted vaccines (based on BA.1) over time.

Increasing risk of breakthrough COVID-19 in outbreaks with high attack rates in European long-term care facilities, July to October 2021.

We collected data from 10 EU/EEA countries on 240 COVID-19 outbreaks occurring from July-October 2021 in long-term care facilities with high vaccination coverage. Among 17,268 residents, 3,832 (22.2%) COVID-19 cases were reported. Median attack rate was 18.9% (country range: 2.8-52.4%), 17.4% of cases were hospitalised, 10.2% died. In fully vaccinated residents, adjusted relative risk for COVID-19 increased with outbreak attack rate. Findings highlight the importance of early outbreak detection and rapid containment through effective infection prevention and control measures.

Psychometric Properties and Construct Validity of the Short Version of the Self-Report Psychopathy Scale in a Southern European Sample.

The Self-Report Psychopathy Scale-Short Form (SRP-SF) is a brief measure of psychopathy, developed via model-based test theory. The SRP-SF has a 4-factor structure with items reflecting affective, interpersonal, lifestyle, and antisocial domains, in line with the Psychopathy Checklist-Revised (PCL-R), which can be aggregated to form the traditional F1 and F2 dimensions of psychopathy. Previous research indicates the SRP is a viable tool for examining the prevalence of psychopathic propensities and their correlates in nonoffender populations. Currently, a substantial amount of nonoffender research on psychopathy is conducted in North America. Here, we inspect the psychometric properties of the SRP-SF and probe its association with general personality and empathy in a large southern European (Portuguese) community sample. Consistent with previous studies, results indicated good fit for the 4-factor model, including for separate female and male subsamples, good internal consistency across its scales and subscales, and the predicted pattern of associations with the correlates of psychopathy. The results of this cross-cultural study provide further evidence of the validity of the SRP-SF in the assessment of psychopathy in community samples, and help to extend the nomological net on the larger construct to a southern European sample.

Psychophysiological Synchrony During Verbal Interaction in Romantic Relationships.

Previous studies about romantic relationships have shown that the reciprocal influence between partners occurs not only at the behavioral and socio-emotional levels, but also at the psychophysiological level. This reciprocal influence is expressed in a pattern of physiological synchrony between partners (i.e., coordinated dynamics of the physiological time series). The main aim of the present study was to explore the presence of a pattern of physiological synchrony in electrodermal activity (EDA) during a couple interaction task. A second objective was to compare the synchrony levels during a negative interaction condition versus a positive interaction condition. Finally, we analyzed the association between synchrony and self-perception of empathy, dyadic empathy, and relationship satisfaction. Thirty-two couples (64 individuals) participated in this study. Each couple performed a structured interaction task while the EDA of both partners was being registered. The quantification of synchrony was based on the cross-correlation of both members' EDA time-series. In order to control for coincidental synchrony, surrogate datasets were created by repeatedly shuffling the original data of spouses X and Y of a dyad and computing synchronies on the basis of the shuffled data (pseudosynchrony values). Our results confirmed the presence of significant EDA synchrony during the interaction. We also found that synchrony was higher during the negative interactions relative to the positive interactions. Additionally, physiological synchrony during positive interaction was higher for those couples in which males scored higher in dyadic empathy. The clinical implications of these findings are discussed.

Estudios anteriores acerca de las relaciones amorosas han demostrado que la influencia recíproca entre las parejas no solo ocurre en los niveles conductuales y socioemocionales, sino también en el nivel psicofisiológico. Esta influencia recíproca se expresa en un patrón de sincronía fisiológica entre los integrantes de la pareja (p. ej.: la dinámica coordinada de las series temporales fisiológicas). El objetivo principal del presente estudio fue analizar la presencia de un patrón de sincronía fisiológica en la actividad electrodérmica (AED) durante una tarea de interacción de la pareja. Un segundo objetivo fue comparar los niveles de sincronía durante una situación de interacción negativa frente a una situación de interacción positiva. Finalmente, analizamos la asociación entre la sincronía y la autopercepción de empatía, la empatía diádica y la satisfacción con la relación. Treinta y dos parejas (64 personas) participaron en este estudio. Cada pareja llevó a cabo una tarea de interacción estructurada mientras se registraba la AED de ambos integrantes de la pareja. La cuantificación de la sincronía se basó en la correlación cruzada de las series temporales de la AED de ambos miembros. A fin de controlar la sincronía simultánea, se crearon conjuntos de datos sustitutos entremezclando continuamente los datos originales de los cónyuges X e Y de una díada y computando las sincronías sobre la base de los datos mezclados (valores de seudosincronía). Nuestros resultados confirmaron la presencia de una sincronía considerable de la AED durante la interacción. También descubrimos que la sincronía fue mayor durante las interacciones negativas respecto de las interacciones positivas. Además, la sincronía fisiológica durante la interacción positiva fue mayor en aquellas parejas en las cuales los hombres obtuvieron un puntaje más alto en la empatía diádica. Se debaten las consencuencias clínicas de estos resultados.

Psychometric properties of the questionnaire of cognitive and affective empathy in a Portuguese sample.

Empathy is an important concept in psychology and cognitive neuroscience. Despite the controversy around its definition, most researchers would agree that empathy is a multidimensional phenomenon which involves a vicarious experience of another person's affective state and an understanding of another person's affective experience. Self-report measures of empathy constitute an important tool for both research and clinical practice. The main goal of this study was to adapt and study the psychometric properties of the Questionnaire of Cognitive and Affective Empathy (QCAE), a worldwide used measure of empathy, in a Portuguese community sample (N = 562). Confirmatory factor analyses supported the factor structure of the original QCAE. Results show that the Portuguese version of the QCAE has sound psychometric properties, with good structural validity and internal consistency for both scales (i.e., affective and cognitive) and respective subscales of the instrument (i.e., Emotion Contagion, Proximal Responsivity, Peripheral Responsivity, Perspective Taking and Online Simulation). We tested both a five correlated factor structure (Model 1) and a second-order model that postulates the affective and cognitive dimensions (Model 2). Our results show that while both models present acceptable goodness of fit indices, Model 1 performs slightly better. In conclusion, the Portuguese version of the QCAE may prove a useful tool for future cross-cultural assessments of empathy in both research and clinical practice.

Testosterone and Cortisol Jointly Predict the Ambiguity Premium in an Ellsberg-Urns Experiment.

Previous literature has tried to establish whether and how steroid hormones are related to economic risk-taking. In this study, we investigate the relationship between testosterone (T) and cortisol (C) on one side and attitudes toward risk and ambiguity on the other. We asked 78 male undergraduate students to complete several tasks and provide two saliva samples. In the task "Reveal the Bag," participants expressed their beliefs on an ambiguous situation in an incentivized framework. In the task "Ellsberg Bags," we elicited from the participants through an incentive-compatible mechanism the reservation prices for a risky bet and an ambiguous bet. We used the difference between the two prices to calculate each participant's ambiguity premium. We found that participants' salivary T and C levels jointly predicted the ambiguity premium. Participants featuring comparatively lower levels of T and C showed the highest levels of ambiguity aversion. The beliefs expressed by a subset of participants in the "Reveal the Bag" task rationalize (in a revealed preference sense) their choices in the "Ellsberg Bags" task.

Borderline Ovarian Tumor during Pregnancy: A Case Report.

We report a case of a 33 year-old pregnant woman who was diagnosed at the time of the first trimester ultrasound with a multilocular solid arising form the right ovary. An abdominal MRI was performed afterwards and it revealed a pelvic mass, developing from the right ovary, with a liquid component but with a major solid area. CA 125 was within the normal range values. A laparotomy followed by right salpingo-oophorectomy was performed at 14 weeks of gestation and both the frozen section and the definitive histology revealed a borderline mucinous ovarian tumor. Ovarian tumors of low malignant potential comprise 10%-20% of all ovarian malignancies. They carry an excellent prognosis with 95%-99% long-term survival. Whereas in the past, radical surgery (hysterectomy and bilateral salpingo-oophorectomy with peritoneal staging) was standard regardless of the age of the patient, unilateral salpingo-oophorectomy with or without staging has become the recommended management for women who desire childbearing. In the absence of large prospective randomized trials it is difficult to know which are the best management practices and especially to determine the right moment during pregnancy to perform surgery in these patients.

Adaptação para a língua portuguesa do Questionário de Experiências Dissociativas Peritraumáticas (QEDP) numa amostra de bombeiros / Portuguese adaptation of the Peritraumatic Dissociation Experiences Questionnaire (PDEQ) in a sample of ambulance personal

CONTEXTO: A dissociação peritraumática é uma resposta no momento da exposição a uma situação ameaçadora que tem se mostrado um preditor significativo de perturbação psicológica a longo prazo, nomeadamente perturbação pós-estresse traumático. OBJETIVOS: Fazer a adaptação para português do Peritraumatic Dissociation Experiences Questionnaire numa população altamente exposta a situações traumáticas, como é o caso dos bombeiros. MÉTODO: Após a tradução e o estudo dos itens, fizeram-se a aplicação e a análise psicométrica com uma amostra de 170 bombeiros, que relataram exposição traumática e que também preencheram uma escala de Perturbação de Pós-Estresse Traumático. RESULTADOS: Os dados indicam que se trata de um instrumento com uma boa consistência interna (alfa de Cronbach = 0,87) e cuja validade de construto o torna adequado para a avaliação das respostas dessa população no exercício da sua profissão. Para além disso, a correlação elevada com os sintomas de perturbação pós-estresse traumático sugere ainda uma boa validade convergente. DISCUSSÃO: Atendendo ao fato de que a dissociação peritraumática prevê PPST, o recurso a um instrumento que revela boas capacidades psicométricas pode ajudar a identificar as pessoas que desenvolverão perturbação após exposição a trauma.

BACKGROUND: Peritraumatic dissociation is a reaction that occurs in the moment someone is exposed to a threatening situation and has shown to be an important predictor of long term psychological disorder, including post traumatic stress disorder. OBJECTIVES: To make the psychometric adaptation of Peritraumatic Dissociation Experiences Questionnaire in Portuguese ambulance personnel that report high exposure to trauma. The instrument has been widely used in research, and was initially designed to analyse peritraumatic dissociation in emergency personnel. METHODS: After items translation and study, 170 ambulance personnel filled it, and a PTSD scale. RESULTS: Data show that the instrument has good internal consistency (Cronbach alfa = 0.87) and construct validity, suggesting that it is appropriate to evaluate the reaction of emergency workers during the duties of their professions. It also has a high correlation with post traumatic stress disorder symptoms, suggesting a good convergent validity. DISCUSSION: Peritraumatic dissociation is a good predictor of PTSD. Taking this into account, the availability of this instrument in Portuguese, with good psychometric characteristics, can help in the identification of the persons who will develop symptoms after a traumatic experience.

When what I wish makes me worse ... to make coherence flexible.

This paper describes a psychotherapeutic constructivist intervention oriented to the resolution of implicative dilemmas, in order to promote personal change. It presents a clinical case study of a client with depression and with some dependent and obsessive functioning. The Repertory Grid Technique was administered along with symptom assessment (SCL-90-R) both at beginning and end of the psychotherapeutic process. Exploring themes emerged from Repgrid, several narratives, experiential and metaphoric strategies were used in order to explore and reconstruct meanings associated with the five implicative dilemmas found. The therapeutic process succeeds at solving dilemmas as found in the post-therapy assessment. This resolution was accompanied by symptom reduction. In conclusion, the utility of implicative dilemmas as a marker to understand the therapeutic impasse and dysfunctional system coherence is discussed, as well as the efficacy of the strategies used in this clinical case concerning its adaptation to working with implicative dilemmas that prevent therapeutic process.

History of childhood abuse in Portuguese parents.

OBJECTIVE: The study examines the self-reported prevalence of childhood physical and sexual abuse in a large sample of Portuguese parents. METHOD: Nearly 1,000 parents (506 mothers and 426 fathers) were selected through public primary schools from the Northern area of Portugal. All completed the Portuguese version of the Childhood History Questionnaire (CHQ) [Journal of Family Violence 5 (1990) 15]. RESULTS: Results show that the prevalence of abuse was 73%, but more severe physical abuse involving sequelae/injury was reported by 9.5%. Most physical abuses began prior to age 13, with half continuing after age 13. No gender differences were found for rates of physical abuse. However, among the milder physical abuse without sequelae/injury, those women who experienced "whipping" or "slapping/kicking" were more likely to do so from their mothers than fathers. Among men who were "slapped/kicked" this was more likely to be from their fathers. Low rates of sexual abuse were found at 2.6% with no gender or age differences. Lack of a supportive adult in childhood related to the more severe abuses, but only in adolescence. Portuguese rates of abuse were consistently lower than those reported in USA and Spanish studies using the CHQ. CONCLUSIONS: This is the first retrospective, self-report study of childhood abuse in a large sample of Portuguese parents and, even with a participation rate of 69%, shows lower rates than in US and Spanish samples.
