Published: September 2023

IntroductionMagnetoencephalography (MEG) is a powerful technique for studying the human brain function. However, accurately estimating the number of sources that contribute to the MEG recordings remains a challenging problem due to the low signal-to-noise ratio (SNR), the presence of correlated sources, inaccuracies in head modeling, and variations in individual anatomy.MethodsTo address these issues, our study introduces a robust method for accurately estimating the number of active sources in the brain based on the F-ratio statistical approach, which allows for a comparison between a full model with a higher number of sources and a reduced model with fewer sources. Using this approach, we developed a formal statistical procedure that sequentially increases the number of sources in the multiple dipole localization problem until all sources are found.ResultsOur results revealed that the selection of thresholds plays a critical role in determining the method's overall performance, and appropriate thresholds needed to be adjusted for the number of sources and SNR levels, while they remained largely invariant to different inter-source correlations, translational modeling inaccuracies, and different cortical anatomies. By identifying optimal thresholds and validating our F-ratio-based method in simulated, real phantom, and human MEG data, we demonstrated the superiority of our F-ratio-based method over existing state-of-the-art statistical approaches, such as the Akaike Information Criterion (AIC) and Minimum Description Length (MDL).DiscussionOverall, when tuned for optimal selection of thresholds, our method offers researchers a precise tool to estimate the true number of active brain sources and accurately model brain function.

BackgroundThere is a need for re-designing the health service for children suffering from complex and compound health complaints. Based on a previous register study, we have developed criteria to select patients with complex health complaints eligible for an Intervention with an interdisciplinary professional team. The team consists of a pediatrician, a psychologist and a physiotherapist.MethodTo identify children with complex health complaints who would benefit from this intervention, we have selected a group of patients by using a set of criteria consisting of the following criteria: multi-referred young school age children referred to both mental health service and pediatric service. This study focuses on the feasibility of these criteria by measuring participation and compliance and by gathering feedback from the team members in the interdisciplinary team.ResultsAmong 677 children aged 6−12 years referred to a regional hospital, we found 32 (5%) children eligible for the interdisciplinary Intervention according to the applied criteria. Only 6% of the invited parents declined to participate in the intervention. According to the interdisciplinary team, the intervention was found suitable for 88% of the children.ConclusionThe suggested criteria seemed feasible, in terms of identifying eligible patients for this interdisciplinary Intervention for children with complex health complaints.Clinical Trial RegistrationRetrospectively registered on www.clinicaltrials.gov, ID NCT04652154, on the 3rd of December 2020.

The impact of prenatal maternal mental health on offspring socioemotional development is substantial and enduring. Existing literature primarily focuses on the effects of psychological distress during pregnancy, emphasizing adverse child outcomes. Recent studies, however, highlight the unique impact of positive maternal mental health on child outcomes. To elucidate the differential associations of maternal psychological distress and positive mental health during pregnancy with child outcomes, we conducted a systematic literature search and random-effects meta-analyses on studies investigating the associations of prenatal maternal mental health with child socioemotional development. Our analyses, comprising 74 studies with 321,966 mother-child dyads across 21 countries, revealed significant associations of prenatal psychological distress with both adverse and positive child socioemotional outcomes. Notably, the effect sizes for the association of psychological distress with positive child outcomes were smaller compared to adverse outcomes. Positive prenatal mental health, on the other hand, was significantly associated with positive socioemotional outcomes but not adverse outcomes. This meta-analysis highlights the independence of negative and positive prenatal mental health constructs and their distinct relationships with child socioemotional development. The findings underscore the importance of considering the positive spectrum of maternal mental health and developmental outcomes to enhance our understanding of prenatal influences on child development.

Introduction: Dihydropyrimidine dehydrogenase (DPD), encoded by DPYD gene, is the rate-limiting enzyme responsible for fluoropyrimidine (FP) catabolism. DPYD gene variants seriously affect DPD activity and are well validated predictors of FP-associated toxicity. DPYD variants rs3918290, rs55886062, rs67376798, and rs75017182 are currently included in FP genetic-based dosing guidelines and are recommended for genotyping by the European Medicines Agency (EMA) before treatment initiation. In Greece, however, no data exist on DPYD genotyping. The aim of the present study was to analyze prevalence of DPYD rs3918290, rs55886062, rs67376798, rs75017182, and, additionally, rs1801160 variants, and assess their association with FP-induced toxicity in Greek cancer patients.Methods: Study group consisted of 313 FP-treated cancer patients. DPYD genotyping was conducted on QuantStudio ™ 12K Flex Real-Time PCR System (ThermoFisher Scientific) using the TaqMan® assays C__30633851_20 (rs3918290), C__11985548_10 (rs55886062), C__27530948_10 (rs67376798), C_104846637_10 (rs75017182) and C__11372171_10 (rs1801160).Results: Any grade toxicity (1-4) was recorded in 208 patients (66.5%). Out of them, 25 patients (12%) experienced grade 3-4 toxicity. DPYD EMA recommended variants were detected in 9 patients (2.9%), all experiencing toxicity (p = 0.031, 100% specificity). This frequency was found increased in grade 3-4 toxicity cases (12%, p = 0.004, 97.9% specificity). DPYD deficiency increased the odds of grade 3-4 toxicity (OR: 6.493, p = 0.014) and of grade 1-4 gastrointestinal (OR: 13.990, p = 0.014), neurological (OR: 4.134, p = 0.040) and nutrition/metabolism (OR: 4.821, p = 0.035) toxicities. FP dose intensity was significantly reduced in DPYD deficient patients (β = −0.060, p &lt;0.001). DPYD rs1801160 variant was not associated with FP-induced toxicity or dose intensity. Triple interaction of DPYD*TYMS*MTHFR was associated with grade 3-4 toxicity (OR: 3.725, p = 0.007).Conclusion: Our findings confirm the clinical validity of DPYD reduced function alleles as risk factors for development of FP-associated toxicity in the Greek population. Pre-treatment DPYD genotyping should be implemented in clinical practice and guide FP dosing. DPYD*gene interactions merit further investigation as to their potential to increase the prognostic value of DPYD genotyping and improve safety of FP-based chemotherapy.

Published: September 2023

BackgroundThe psychological impact of the COVID-19 pandemic on healthcare professionals has been widely studied, along with different strategies to minimize it. However, professionals’ assessment of the social support received and the factors that mitigated their fear of contagion have not been described. This study aimed to assess healthcare professionals’ satisfaction with the social support and information received and their efforts to self-isolate to avoid infecting loved ones in Chile, Colombia, and Ecuador.MethodsA cross-sectional online survey, conducted from July to September 2020 in three Latin American countries, elicited healthcare professionals’ satisfaction with social support from colleagues, their community, the media, and scientific societies; as well as the information received about the evolution of the pandemic and measures to avoid contagion. The EASE scale was used to measure acute stress.ResultsSurvey responses were received from 700 professionals. The response rate per country exceeded the estimated sample size except in the case of Colombia, which was 81.4%. In general, peer support was highly valued, though satisfaction was lower in high-risk units (p &lt; 0.001). Those who directly assisted COVID-19 patients perceived the least community support (p = 0.023). Professionals from high-risk units (p = 0.013) and those who experienced greater acute stress (p = 0.05) assigned the lowest rating to the information offered by the centre on the pandemic. Men perceived more support from colleagues and better information from the centre than women (p &lt; 0.05). Just 10.7% of professionals changed their residence during the pandemic, but those who worked in high-risk areas self-isolated more frequently (p = 0.026).ConclusionIn the early stages of the COVID-19 pandemic, healthcare professionals in Chile, Colombia, and Ecuador greatly valued the support received from their peers. Being infected with COVID-19, working in high-risk areas, experiencing higher self-reported acute stress, and having an infected co-worker were predictors for self-isolation to protect their relatives. These results point to the appropriateness of putting in place institutional resources based on peer support and specific communication strategies and action protocols to build resilience and responsiveness to future health crises.

Authors: Park Seon-Min , Kim Jung-Hee 
Published: September 2023

IntroductionThe gender-friendliness barriers in nursing programs (GFB-NP) were used to measure perceived gender affinity among male nursing students in nursing education programs. Originally developed in Taiwan, this scale has not been used in Korea. The purpose of this study is to confirm the reliability and validity of the GFB-NP scale for Korean male nursing students.MethodsA convenience sample of male nursing students enrolled in the 1st to 4th year of nursing departments at five four-year universities located in three cities in Korea was used in the study. To confirm the validity and factor structure of the scale, both exploratory factor analysis and confirmatory factor analysis were employed.ResultsThe results support a four-factor structure: Professional acquisition opportunity, peer interaction, sociocultural prejudice, and gender role attitude. We confirmed that the Korean version of the GFB-NP is an appropriate tool for measuring the gender-friendliness educational environment perceived by male nursing students in nursing education.DiscussionThe GFB-NP will serve as a framework for developing counseling and management strategies to help male nursing students successfully adapt to school life within the nursing education curriculum. Research with a longitudinal study design is recommended to investigate the progression of school adaptation through undergraduate program courses.
The effect of intranasal oxytocin on social reward processing in humans: a systematic review
Authors: Kraus Jakub , Výborová Eliška , Silani Giorgia 
Published: September 2023

Understanding the neurobiology of social reward processing is fundamental, holding promises for reducing maladaptive/dysfunctional social behaviors and boosting the benefits associated with a healthy social life. Current research shows that processing of social (vs. non-social) rewards may be driven by oxytocinergic signaling. However, studies in humans often led to mixed results. This review aimed to systematically summarize available experimental results that assessed the modulation of social reward processing by intranasal oxytocin (IN-OXY) administration in humans. The literature search yielded 385 results, of which 19 studies were included in the qualitative synthesis. The effects of IN-OXY on subjective, behavioral, and (neuro)physiological output variables are discussed in relation to moderating variables—reward phase, reward type, onset and dosage, participants’ sex/gender, and clinical condition. Results indicate that IN-OXY is mostly effective during the consumption (“liking”) of social rewards. These effects are likely exerted by modulating the activity of the prefrontal cortex, insula, precuneus, anterior cingulate cortex, amygdala, and striatum. Finally, we provide suggestions for designing future oxytocin studies.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021278945, identifier CRD42021278945.

IntroductionIdentifying stakeholders’ needs is crucial to informing decisions and policy development. This study aims to identify healthcare and social-related needs and effective strategies associated with COVID-19 from the first-person perspectives of patients and healthcare providers.MethodsCross-sectional online survey design including qualitative open-ended questions, conducted in primary care and hospital settings across Spain, with 12 out of 19 regions represented. Adults aged 18 years and older, who (a) resided in Spain and had a history of COVID-19 or (b) worked as healthcare providers delivering direct or indirect care for people with COVID-19 in Spanish primary care or hospitals during 2020 were eligible to participate. Recruitment was conducted via social-media networks (Twitter, LinkedIn, and WhatsApp) and communication channels of key organizations including patient and professional associations and groups. A total of 182 people were invited to complete the surveys and 76 people completed the surveys (71% women), of which 33 were home-isolated patients, 14 were hospitalized patients, 16 were primary care professionals, and 13 were hospital care professionals.ResultsA total of 327 needs and 86 effective strategies and positive aspects were identified across surveys and classified into the following overarching themes: (i) Accessibility, (ii) Basic needs, (iii) Clinical care, (iv) Person-and-family centered care, (v) Caring for the healthcare professional, (vi) Protocolization, information, health campaigns, and education, (vii) Resource availability, (viii) and Organizational needs/strategies.DiscussionFindings indicate the Spanish health and social care systems were generally unprepared to combat COVID-19. Implications for research, practice, and policy focus on integrating first-person perspectives as best practice to identify, prioritize and address needs to increase health and social care systems capacity and preparedness, as well as providing well-co-coordinated responses across government, healthcare, and non-government sectors to promote and protect the physical and mental health of all.

BackgroundA large number of workers attend work despite being ill. Attending work during sickness can have a number of consequences for the worker (e.g., worsening of physical and mental condition), for co-workers, and for the company, and for service users.ObjectivesThe aim of this study was to assess the factors influencing presenteeism and mental health of workers during the COVID-19 pandemic.MethodsA systematic review following the PRISMA format was conducted in the PubMed, Scopus, Web of Science (WoS), Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycInfo, and ScienceDirect electronic databases in January 2023, using the following key words: Presenteeism, Mental Health, and COVID-19. The eligibility criteria applied were original articles published in English, Spanish, French, German, and Portuguese, workers during the COVID-19 pandemic (data collection date: January 01, 2020 – January 01, 2023), and articles assessing at least one measure of presenteeism and mental health status. Methodological quality was assessed using the critical appraisal tools of the Joanna Briggs Institute. The followed protocol is listed in the International Prospective Register of Systematic Reviews (PROSPERO) with code CRD42023391409.ResultsA total of 25 studies were included in this review recruiting a total of 164,274 participants. A number of factors influencing mental health and sickness presenteeism were identified: (1) mental health-related factors (burnout [in 4 studies], stress [in 9 studies], depression [in 1 study], fear of COVID-19 [in 1 study], no well-being [in 2 studies], etc.); (2) individual factors (health status [in 1 study], being young [in 1 study], workers who experienced interrupted medical care [in 2 studies], having a chronic disease [in 1 study], etc.); (3) factors related to the situation caused by COVID-19 (confinement, symptoms, loss of contract, risk of bankruptcy, etc. [in 1 study each one]); and (4) factors derived from working conditions (organisational support [in 1 study], patient care [in 1 study], work functioning or task performance impairment [in 4 studies], work fatigue [in 2 studies], safety climate [in 1 study], workload [in 1 study], etc.).ConclusionIdentifying the key determinants of presenteeism and understanding the phenomena and origins of sickness presenteeism will help to create a safe working environment and optimal organisational systems to protect vulnerable workers in a pandemic context.Systematic review registrationThe unique identifier is CRD42023391409.
Probing the compositional and rheological properties of gastropod locomotive mucus
Authors: Barajas-Ledesma Edgar , Holland Chris 
Published: September 2023

Gastropods, such as snails and slugs, can excrete mucus to aid in movement and adhesion. However, very few studies have examined the physical relationship between mucus composition and function. Here, we explore the role of mucus polymers (specifically their proteins) and their influence on the material properties of locomotive mucus. Using a range of spectroscopic, thermal, and rheological analytical tools, we characterised locomotive mucus from six gastropod species across four families. We report that all mucus tested consisted of 97%–99% water, and the remaining 1%–3% solid content contained a range of proteins (41–377 kDa, 18 of which are previously undocumented), which we propose contribute to its weak gel behaviour (1.58–36.33 Pa•s at 1 rad/s). Our results indicate that mucus properties are also grouped at the family level, suggesting that niche-specific adaptation occurs in these materials. We expect our study to offer a broader approach to how a correlation between properties is crucial for understanding the stability and functionality of snail mucus.

BackgroundMorphological involvement of endocrine glands, such as the pituitary gland, remain uninvestigated in dogs with canine visceral leishmaniasis. Therefore, this study investigated the presence of amastigotes of Leishmania spp. and characterized inflammatory changes, highlighting the involvement of TCD3+ lymphocytes in different regions of the pituitary gland of dogs.MethodsSamples were collected from 21 naturally infected dogs and 5 control, uninfected dogs. The different pituitary regions were analyzed in histological sections stained with hematoxylin and eosin (HE) under light microscopy. Inflammation was classified by intensity in a score from 0 to 3, absent (0), mild (1), moderate (2), and marked (3). The immunohistochemical (IHC) evaluation was performed in five high-power fields (hot spot) in a 40x objective of each region with manual counting (Image J1.52ª) of the TCD3+ lymphocytes and for amastigotes analyzed in 40x and 100x objectives. The Shapiro–Wilk test was used to assess the normality of the data. Differences between groups were determined by the Mann Whitney test. The correlation between variables was assessed by Sperman’s correlation test. p &lt; 0.05 were considered statistically significant.ResultsAmastigotes from the pituitary glands of two infected dogs were identified using IHC. The histopathological evaluation stained with hematoxylin and eosin showed greater intensity of inflammation in the pars distalis and pars intermedia regions of infected dogs. IHC for TCD3+ lymphocytes showed a higher median number of immunolabeled cells in pars nervosa in the infected group than in the control group (p &lt; 0.05); and expecting a variation in the distribution and number of these cells in naturally infected dogs, the median of the control group was considered a cut-off point, an increase in T lymphocytes (p &lt; 0.05) was also observed in the pars intermedia and pars distalis of an infected subgroup (n = 10). A moderate significant correlation between the intensity of inflammation and the number of immunolabeled TCD3+ lymphocytes was established in the analyzed pituitary regions, characterizing the occurrence of hypophysitis.ConclusionThese findings presuppose that inflammation and/or the parasite in the pituitary region can result in gland dysfunction, worsening the clinical condition of the patient and compromising the efficiency of treatment and prognosis.
