The COVID-19 pandemic led many couples to stay at home together with minimal contact with others. As social distancing measures reduced contact with outside households, many partners could seek support only from one another. In two studies using a sequential mixed methods design, we investigated support-seeking behaviors in romantic relationships during COVID-19. In the qualitative study, semi-structured interviews (n = 48) showed differences in how and why partners seek support with an initial consideration of the role of attachment. We identified the following themes: direct support-seeking, indirect support-seeking, (in)dependence, and gender dynamics. In the quantitative study (n = 588), high COVID-19 worry, high attachment anxiety, and low attachment avoidance were associated with more support-seeking. Interestingly, we also found that when COVID-19 worry was high, individuals high in attachment avoidance were more likely to report seeking support. The paper provides a unique insight into the impact of COVID-19 on support-seeking behaviors in romantic relationships.

The main objective of this study was to determine whether the common Y-haplogroups were be associated with the risk of developing severe COVID-19 in Spanish male. We studied 479 patients who required hospitalization due to COVID-19 and 285 population controls from the region of Asturias (northern Spain), They were genotyped for several polymorphisms that define the common European Y-haplogroups. We compared the frequencies between patients and controls aged ≤ 65 and >65 years. There were no different haplogroup frequencies between the two age groups of controls. Haplogroup R1b was less common in patients aged ≤65 years. Haplogroup I was more common in the two patient´s groups compared to controls (p = 0.02). Haplogroup R1b was significantly more frequent among hypertensive patients, without difference between the hypertensive and normotensive controls. This suggested that R1b could increase the risk for severe COVID-19 among male with pre-existing hypertension. In conclusion, we described the Y-haplogroup structure among Asturians. We found an increased risk of severe COVID-19 among haplogroup I carriers, and a significantly higher frequency of R1b among hypertensive patients. These results indicate that Y-chromosome variants could serve as markers to define the risk of developing a severe form of COVID-19.

The COVID-19 pandemic brought unplanned service disruption for breast cancer diagnostic, treatment and support services. This scoping review describes these changes and their impact in the UK and the Republic of Ireland based on studies published between January 2020 and August 2023. Thirty-four of 569 papers were included. Data were extracted and results thematically organized. Findings include fewer new cases; stage shift (fewer early- and more late-stage disease); and changes to healthcare organization, breast screening and treatment. Examples are accepting fewer referrals, applying stricter referral criteria and relying more on virtual consultations and multi-disciplinary meetings. Screening service programs paused during the pandemic before enacting risk-based phased restarts with longer appointment times to accommodate reduced staffing numbers and enhanced infection-control regimes. Treatments shifted from predominantly conventional to hypofractionated radiotherapy, fewer surgical procedures and increased use of bridging endocrine therapy. The long-term impact of such changes are unknown so definitive guidelines for future emergencies are not yet available. Cancer registries, with their large sample sizes and population coverage, are well placed to monitor changes to stage and survival despite difficulties obtaining definitive staging during diagnosis because surgery and pathological assessments are delayed. Multisite longitudinal studies can also provide guidance for future disaster preparedness.

The ideal vaccines for combating diseases that may emerge in the future require more than simply inactivating a few pathogenic strains. This study aims to provide a peptide-based multi-epitope vaccine effective against various severe acute respiratory syndrome coronavirus 2 strains. To design the vaccine, a library of peptides from the spike, nucleocapsid, membrane, and envelope structural proteins of various strains was prepared. Then, the final vaccine structure was optimized using the fully protected epitopes and the fynomer scaffold. Using bioinformatics tools, the antigenicity, allergenicity, toxicity, physicochemical properties, population coverage, and secondary and three-dimensional structures of the vaccine candidate were evaluated. The bioinformatic analyses confirmed the high quality of the vaccine. According to further investigations, this structure is similar to native protein and there is a stable and strong interaction between vaccine and receptors. Based on molecular dynamics simulation, structural compactness and stability in binding were also observed. In addition, the immune simulation showed that the vaccine can stimulate immune responses similar to real conditions. Finally, codon optimization and in silico cloning confirmed efficient expression in Escherichia coli. In conclusion, the fynomer-based vaccine can be considered as a new style in designing and updating vaccines to protect against coronavirus disease.

Although hate speech against Asian American youth has intensified in recent years-fueled, in part, by anti-Asian rhetoric associated with the COVID-19 pandemic-the phenomenon remains largely understudied at scale and in relation to the role of schools prior to the pandemic. This study describes the prevalence of hate speech against Asian American adolescents in the US between 2015 and 2019 and investigates how school-related factors are associated with whether Asian American youth are victims of hate speech at school. Analyses are based on a sample of 938 Asian American adolescents (Mage = 14.8; 48% female) from the three most recently available waves (2015, 2017, and 2019) of the School Crime Supplement to the National Crime Victimization Survey. On average, approximately 7% of Asian Americans were targets of hate speech at school between 2015 and 2019, with rates remaining stable over time. Findings also indicate that students had lower odds of experiencing hate speech if they attended schools with a stronger authoritative school climate, which is characterized by strict, yet fair disciplinary rules coupled with high levels of support from adults. On the other hand, Asian American youth faced higher odds of experiencing hate speech if they were involved in school fights. Authoritative school climate and exposure to fights are malleable and can be shaped directly by broader school climate related policies, programs and interventions. Accordingly, efforts to promote stronger authoritative climates and reduce exposure to physical fights hold considerable potential in protecting Asian American youth from hate speech at school.

Social events may provide important cues that influence the sense of reality, including the perception that conspiracy theories are plausible. Using longitudinal panel data collected in the UK from March 2020 to December 2021, this study aims to identify whether social events influenced the strength of the association between conspiracy mentality and vaccine intentions during the COVID-19 pandemic. Consistent with previous research, the conspiracy mentality was a significant predictor of vaccine intentions across three-time points, but also that conspiracy mentality measured in March 2020 predicted that participants were more hesitant to the vaccines in December 2020. The primary finding was that different social events moderated the strength of the correlation between conspiracy mentality and vaccine intentions within similar participants. Conspiracy mentality became more vital to evaluate COVID-19 vaccines in December 2020, when the vaccination program was about to commence.

This study sought to identify the behavioural and social drivers of vaccination in 16,745 older Australians. We analysed and compared influences on COVID-19 vaccination intention and uptake using prospectively collected survey data from the Sax Institute's 45 and Up Study. Vaccination intention increased with older age (adjusted odds ratio [aOR]:1.03; 95 % confidence interval [CI]: 1.01-1.04; p = .002), a belief that the vaccine is important for the person's own health (aOR: 5.17; 95 % CI: 4.23-6.24; p < .001), is safe (aOR:2.64; 95 % CI: 2.19-3.2; p < .001), and trusted by the person (aOR:6.79; 95 % CI: 5.59-8.26 p < .001); concern about contracting COVID-19 (aOR:1.78; 95 % CI: 1.47-2.17; p < .001); having enough information about COVID-19 vaccines (aOR:1.99; 95 % CI: 1.65-2.29; p < .001); a belief that most adults will receive a COVID-19 vaccine (aOR:2.31; 95 % CI: 1.93-2.77; p < .001); and a belief that family and friends wanted the person to receive a COVID-19 vaccine (aOR:6.07; 95 % CI: 5.06-7.27; p < .001). The same factors contributed to increased vaccine uptake, with the exception of age and the belief that the person had enough information about the vaccine. Concern that the vaccine will cause a serious reaction was associated with both lower intention (aOR:0.35; 95 % CI: 0.29-0.43; p < .001) and lower uptake (aOR:0.61; 95 % CI: 0.46-0.81; p < .001) while lower intention was also associated with low decisional autonomy (aOR:0.37; 95 % CI: 0.22-0.62; p < .001). Intentions changed over time and a change towards vaccination was associated with perceptions of vaccine safety. Access barriers played a role in the non-vaccination of otherwise intending older Australians. Messaging that is adaptive to safety concerns, emphasises vaccine benefits, leverages social norms, and targets people who make decisions for older Australians may be helpful for influencing vaccination intentions and increasing vaccine uptake.

Autonomous motivation is considered a powerful driver of health behaviour, but less is known about the specific roles played by basic needs. Drawing on the context of the COVID-19 pandemic, this research examined basic needs as a motivational determinant of vaccination. We hypothesized that satisfaction of basic needs (autonomy, competence, relatedness) has both a direct and an indirect effect (through trust in science and government) on vaccine hesitancy. Two studies (Study 1: N = 968 French and British; Study 2, pre-registered: N = 716 Americans) tested our hypotheses and compared vaccinated and non-vaccinated individuals using multigroup structural equation models. We found positive direct (in both studies) and indirect (in Study 1) effects of autonomy satisfaction on vaccine acceptance. In contrast, competence satisfaction was directly and indirectly, via science mistrust, related to vaccine hesitancy, particularly among non-vaccinated people. Competence satisfaction also indirectly reduced the intention to vaccinate in both studies. We found no impact of relatedness. Complementing previous work on self-determination theory, our research demonstrates the importance of considering the distinct roles of basic needs. Moreover, we highlight that increasing autonomy and science trust may be an efficient strategy to improve vaccine acceptance and vaccination, even among reluctant individuals.

The Immunization and Vaccine-related Implementation Research Advisory Committee (IVIR-AC) is the World Health Organization's key standing advisory body to conduct an independent review of research, particularly of transmission and economic modeling analyses that estimate the impact and value of vaccines. From 26th February-1st March 2024, at its first of two semi-annual meetings, IVIR-AC provided feedback and recommendations across four sessions; this report summarizes the proceedings and recommendations from that meeting. Session topics included modeling of the impact and cost-effectiveness of the R21/Matrix-M malaria vaccine, meta-analysis of economic evaluations of vaccines, a global analysis estimating the impact of vaccination over the last 50 years, and modeling the impact of different RTS,S malaria vaccine dose schedules in seasonal settings.

The public health insurance in Germany will face huge economic challenges in the upcoming years. New diagnostic and therapeutic methods as well as the demographic change contribute to constantly rising expenditure. Although incentives for health-promoting behaviour or financial sanctions for an unhealthy lifestyle have been already discussed in the past, there has been a general reluctance to legally establish corresponding mechanisms for fear of eroding solidarity and increasing state control. In the course of the Coronavirus pandemic however, a stronger awareness rose to the fact that personal health-related life choices can have a huge impact on the stability of the healthcare system including public health insurance. Not only in Germany but throughout much of Europe, the pandemic led to a new and more fundamental debate about the relationship between individual responsibility for personal health and the wider responsibility for public health assumed by the community of solidarity.

This contribution examines the compatibility of mandatory vaccination with the European Convention on Human Rights (ECHR) through an analysis of the relevant ECHR rights and related case law of the European Court of Human Rights (ECtHR). By focusing on Article 8 (Right to Private Life), Article 2 (Right to Life) and Article 9 (Freedom of Thought, Conscience and Religion) ECHR, we formulate conditions under which mandatory vaccination legislation is justified. With that, this analysis aims to provide national legislators with guidance on responsible legislative policy. Additionally, this article discusses the legal framework underlying the Dutch vaccination policy, including developments therein since COVID-19. Furthermore, the role of the European Union in the context of vaccination is briefly discussed. The importance of an extensive societal and parliamentary debate before implementing a mandatory vaccination policy is stressed, as is the need for proportionality in enforcement.

Respiratory symptoms are a frequent manifestation of patients with post-acute sequela of SARS-CoV-2 (PASC), also known as long-COVID. Many cohorts of predominantly hospitalized patients have shown that a significant subset may have persistent chest CT findings for more than 12 months after the acute infection. Proper understanding of the evolving long-term imaging findings and terminology is crucial for accurate imaging interpretation and patient care. The goal of this article is to review the chronic chest CT findings of patients with PASC and common pitfalls.

Inhibition of autophagy is one of the hallmarks of the SARS-CoV-2 infection. Recently it was reported that SARS-CoV-2 protein ORF3a inhibits fusion of autophagosomes with lysosomes via interaction with VPS39 thus preventing binding of homotypic fusion and protein sorting (HOPS) complex to RAB7 GTPase. Here we report that myelin basic protein (MBP), a major structural component of the myelin sheath, binds ORF3a and is colocalized with it in mammalian cells. Co-expression of MBP with ORF3a restores autophagy in mammalian cells, inhibited by viral protein. Our data suggest that basic charge of MBP drives suppression of ORF3a-induced autophagy inhibition as its deaminated variants lost ability to bind ORF3a and counteract autophagy blockade. These results together with our recent findings, indicating that MBP interacts with structural components of the vesicle transport machinery-synaptosomal-associated protein 23 (SNAP23), vesicle-associated membrane protein 3 (VAMP3) and Sec1/Munc18-1 family members, may suggest protective role of the MBP in terms of the maintaining of protein traffic and autophagosome-lysosome fusion machinery in oligodendrocytes during SARS-CoV-2 infection. Finally, our data may indicate that deimination of MBP observed in the patients with multiple sclerosis (MS) may contribute to the previously reported worser outcomes of COVID-19 and increase of post-COVID-19 neurologic symptoms in patients with MS.

The coagulation process has a high potential as a treatment method that can handle pathogenic viruses including emerging enveloped viruses in drinking water treatment process which can lower infection risk through drinking water consumption. In this study, a surrogate enveloped virus, bacteriophage Փ6, and surrogate non-enveloped viruses, including bacteriophage MS-2, T4, ՓX174, were used to evaluate removal efficiencies and mechanisms by the conventional coagulation process with alum, poly‑aluminum chloride, and ferric chloride at pH 5, 7, and 9 in turbid water. Also, treatability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a recent virus of global concern by coagulation was evaluated as SARS-CoV-2 can presence in drinking water sources. It was observed that an increase in the coagulant dose enhanced the removal efficiency of turbidity and viruses, and the condition that provided the highest removal efficiency of enveloped and non-enveloped viruses was 50 mg/L of coagulants at pH 5. In addition, the coagulation process was more effective for enveloped virus removal than for the non-enveloped viruses, and it demonstrated reduction of SARS-CoV-2 Omicron BA.2 over 0.83-log with alum. According to culture- and molecular-based assays (qPCR and CDDP-qPCR), the virus removal mechanisms were floc adsorption and coagulant inactivation. Through inactivation with coagulants, coagulants caused capsid destruction, followed by genome damage in non-enveloped viruses; however, damage to a lipid envelope is suggested to contribute to a great extend for enveloped virus inactivation. We demonstrated that conventional coagulation is a promising method for controlling emerging and re-emerging viruses in drinking water.

Immunodiagnostic tests for detecting dengue virus infections encounter challenges related to cross-reactivity with other related flaviviruses. Our research focuses on the development of a synthetic multiepitope antigen tailored for dengue immunodiagnostics. Selected dengue epitopes involved structural linearity and dissimilarity from the proteomes of Zika and Yellow fever viruses which served for computationally modeling the three-dimensional protein structure, resulting in the design of two proteins: rDME-C and rDME-BR. Both proteins consist of seven epitopes, separated by the GPGPG linker, and a carboxy-terminal 6 × -histidine tag. The molecular weights of the final proteins rDME-C and rDME-BR are 16.83 kDa and 16.80 kDa, respectively, both with an isoelectric point of 6.35. The distinguishing factor between the two proteins lies in the origin of their epitope sequences, where rDME-C is based on the reference dengue proteome, while rDME-BR utilizes sequences from prevalent Dengue genotypes in Brazil from 2008 to 2019. PyMol analysis revealed exposure of epitopes in the secondary structure. Successful expression of the antigens was achieved in soluble form and fluorescence experiments indicated a disordered structure. In subsequent testing, rDME-BR and rDME-C antigens were assessed using an indirect Elisa protocol against Dengue infected serum, previously examined with a commercial diagnostic test. Optimal concentrations for antigens were determined at 10 µg/mL for rDME-BR and 30 µg/mL for rDME-C, with serum dilutions ranging from 1:50 to 1:100. Both antigens effectively detected IgM and IgG antibodies in Dengue fever patients, with rDME-BR exhibiting higher sensitivity. Our in-house test showed a sensitivity of 77.3 % and 82.6 % and a specificity of 89.4 % and 71.4 % for rDME-C and rDEM-BR antigens. No cross-reactivity was observed with serum from Zika-infected mice but with COVID-19 serum samples. Our findings underscore the utility of synthetic biology in crafting Dengue-specific multiepitope proteins and hold promise for precise clinical diagnosis and monitoring responses to emerging Dengue vaccines.
