Perceptual encoding of emotions in interactive bodily expressions.

For social species, e.g., primates, the perceptual analysis of social interactions is an essential skill for survival, emerging already early during development.

Predicting vasovagal reactions to needles with anticipatory facial temperature profiles.

Around one-third of adults are scared of needles, which can result in adverse emotional and physical responses such as dizziness and fainting (e.g. vasovagal reactions; VVR) and consequently, avoidance of healthcare, treatments, and immunizations.

Low awareness of past SARS-CoV-2 infection in healthy plasma donors.

Awareness of infection with SARS-CoV-2 is crucial for the effectiveness of COVID-19 control measures. Here, we investigate awareness of infection and symptoms in relation to antibodies against SARS-CoV-2 in healthy plasma donors. We asked individuals donating plasma across the Netherlands between May 11 and 18 2020 to report COVID-19-related symptoms, and we tested for antibodies indicative of a past infection with SARS-CoV-2.

New blood donors in times of crisis: Increased donation willingness, particularly among people at high risk for attracting SARS-CoV-2.

Background: Traditionally, during crises the number of new blood donors increases. However, the current coronavirus disease 2019 (COVID-19) pandemic created additional barriers to donate due to governmental prevention measures and increased personal health risks. In this report, we examined how the pandemic affected new donor registrations in the Netherlands, especially among groups with higher risk profiles for severe COVID-19.

Unknown, so also unvalued? Blood donation awareness and attitudes of potential donors of Dutch and African descent.

Background And Objectives: Many Western countries face a shortage of African blood donors, while their specific blood groups are needed to transfuse chronic transfusion patients of similar ethnic background. Blood donation awareness and attitudes greatly impact the decision to become a blood donor, but how they are related and differ across ethnic groups is understudied. This study investigated blood donation awareness and attitudes of individuals of Dutch and African descent in the Netherlands.

Blood donation among individuals of African origin in the Netherlands: how are barriers and motivators associated with intention?

Background: Blood donors of African origin are under-represented in high-income Western countries, while their extended blood types closely match chronic transfusion patients with similar ancestral backgrounds. To prevent alloimunisation, it is important to recruit and retain more African blood donors. The aim of this study was to gain insight into blood donation barriers and motivators of individuals of African origin, and to assess how these are associated with the intention to donate blood.

Ferritin measurement IN Donors-Effectiveness of iron Monitoring to diminish iron deficiency and low haemoglobin in whole blood donors (FIND'EM): study protocol for a stepped wedge cluster randomised trial.

Background: Blood donors are at risk for reduced iron stores, because of which donor iron monitoring received increased attention in the last decade. Despite the importance for donor health, international consensus on an appropriate policy for iron monitoring is lacking. Therefore, we conduct a trial to evaluate to what extent ferritin-guided donation intervals are effective in increasing haemoglobin and ferritin levels, decreasing low-haemoglobin deferral, increasing donor return and improving the health of whole blood donors in the Netherlands.

Impact of risk-dependent interventions on low haemoglobin deferral rates in whole blood donors.

Background: Blood donors with a relatively low haemoglobin (Hb) level at their previous donation attempt have an increased risk of Hb deferral at the subsequent donation attempt. The aim of this study was to investigate whether the interventions prolongation of donation interval and/or a dietary advice decrease the Hb deferral rate.

Methods: 11 897 whole blood donors with Hb levels from below to 0·2 mmol/l above the cut-off level for donation received either no intervention, a prolongation of the donation interval to six or twelve months, a dietary advice, or both.

Associations between single nucleotide polymorphisms and erythrocyte parameters in humans: A systematic literature review.

Individual variations in erythrocyte parameters are influenced by factors like sex, age, diet and season. Genetic variations have also been associated with erythrocyte parameters. The aim of this systematic review is to provide an overview of associations between single nucleotide polymorphisms (SNPs) and erythrocyte parameters in humans.

Determinants of blood donation willingness in the European Union: a cross-country perspective on perceived transfusion safety, concerns, and incentives.

Background: Willingness to donate blood depends on personal characteristics, beliefs, and motivations, but also on the cultural context. The aim of this study was to examine whether willingness to donate blood is associated with attitudes toward blood transfusion, personal motivators, and incentives and whether these factors vary across countries in the European Union (EU).

Study Design And Methods: The sample consisted of 27,868 participants, from 28 EU member states, who were interviewed about blood donation and transfusion-related issues for the 2014 round of the Eurobarometer, a country-comparative survey, collected on behalf of the European Commission.

The supply chain of migrant blood donors: an organisational interview study.

Background And Objectives: Migrant blood donors are underrepresented worldwide resulting in shortages of compatible blood products. Prior studies focused on individual barriers and motivators of potential blood donors, but no studies addressed organisational factors of the blood supply chain. This study explored the perceptions and experiences in recruitment and retention of migrant - and potentially rare-blood donors among staff members within the blood supply chain and identified obstacles and solutions in this chain.

Barriers and motivators of Ghanaian and African-Surinamese migrants to donate blood.

African migrants are underrepresented as blood donors in many Western countries, which can lead to shortages of specific blood types for transfusion. More insight in the reasons for this underrepresentation is required to improve blood donor recruitment and retention strategies. The aim of this qualitative study was to explore barriers and motivators for donating blood among migrants of African background.

The Neural Basis of Individual Face and Object Perception.

We routinely need to process the identity of many faces around us, and how the brain achieves this is still the subject of much research in cognitive neuroscience. To date, insights on face identity processing have come from both healthy and clinical populations. However, in order to directly compare results across and within participant groups, and across different studies, it is crucial that a standard task is utilized which includes different exemplars (for example, non-face stimuli along with faces), is memory-neutral, and taps into identity matching across orientation and across viewpoint change.

The Facial Expressive Action Stimulus Test. A test battery for the assessment of face memory, face and object perception, configuration processing, and facial expression recognition.

There are many ways to assess face perception skills. In this study, we describe a novel task battery FEAST (Facial Expressive Action Stimulus Test) developed to test recognition of identity and expressions of human faces as well as stimulus control categories. The FEAST consists of a neutral and emotional face memory task, a face and shoe identity matching task, a face and house part-to-whole matching task, and a human and animal facial expression matching task.

From personal fear to mass panic: The neurological basis of crowd perception.

Recent studies have investigated the neural correlates of how we perceive emotions of individuals or a group of individuals using images of individual bodily expressions. However, it is still largely unknown how we perceive the emotion of a dynamic crowd. This fMRI study used realistic videos of a large group of people expressing fearful, happy or neutral emotions.

The Body Action Coding System II: muscle activations during the perception and expression of emotion.

Research into the expression and perception of emotions has mostly focused on facial expressions. Recently, body postures have become increasingly important in research, but knowledge on muscle activity during the perception or expression of emotion is lacking. The current study continues the development of a Body Action Coding System (BACS), which was initiated in a previous study, and described the involvement of muscles in the neck, shoulders and arms during expression of fear and anger.

The Body Action Coding System I: muscle activations during the perception and expression of emotion.

Body postures provide clear signals about emotional expressions, but so far it is not clear what muscle patterns are associated with specific emotions. This study lays the groundwork for a Body Action Coding System by investigating what combinations of muscles are used for emotional bodily expressions and assessing whether these muscles also automatically respond to the perception of emotional behavior. Surface electromyography of muscles in the arms (biceps and triceps) and shoulders (upper trapezius and deltoids) were measured during both active expression and passive viewing of fearful and angry bodily expressions.

The human and animal baby schema effect: correlates of individual differences.

We investigated the animal and human baby schema effect (BSE) in relation to gender, parental status, and individual features. In three, independent online surveys, conducted during three consecutive years, (Ntotal=1389), ratings of photographs of human and animal infants as well as of adults, sociodemographic variables (age, gender, parental status) and personality attributes (empathy, attachment, interpersonal closeness, narcissism, and need to belong) were assessed. We demonstrated that humans are sensitive to the baby schemata of both humans and animals and that both are weakly positively correlated.

Validation of the Turkish version of the problem areas in diabetes scale.

The Problem Areas in Diabetes (PAID) scale is a widely used self-report measure that can facilitate detection of diabetes-specific emotional distress in clinical practice. The aim of this study was to assess the factor structure and validity of the Turkish version of the PAID. A validation study was conducted among 154 patients with insulin-naïve type 2 diabetes.

Posttraumatic stress following childbirth in homelike- and hospital settings.

Objective: To assess the prevalence of posttraumatic stress disorder (PTSD) following childbirth in homelike versus hospital settings and to determine risk factors for the development of posttraumatic stress symptoms. METHODS.: Multi-center cross-sectional study at midwifery practices, general hospitals and a tertiary (university) referral center.

Measuring posttraumatic stress following childbirth: a critical evaluation of instruments.

Objectives: To evaluate instruments used to assess posttraumatic stress disorder (PTSD) following childbirth with both quantitative (reliability analysis and factor analysis) and qualitative (comparison of operationalization) techniques.

Methods: An unselected population of 428 women completed the Traumatic Event Scale-B (TES-B) and the PTSD Symptom Scale-Self Report (PSS-SR) 2-6 months after delivery.

Results: Assessment of internal consistency yielded similar results for the TES-B and PSS-SR (Cronbach's alpha = 0.

Re predictors of quality of life in hospitalized cardiac patients.

A recent and interesting publication by Bruscia, Shultis, Dennery and Dileo (2008a) indicated that Sense of Coherence might be a significant predictor of Quality of Life in cardiac patients. In this short critique paper, some possible shortcomings of this study will be discussed.
