The use of dietary supplements (DSs) has been steadily increasing all over the world and additionally, the sales of DSs have dynamical increased in the wake of coronavirus disease 2019 (COVID-19) in most of the countries. We investigated DSs phenomenon in 2020 through (1) exploration of Google searches worldwide and in Poland (with Google Trends (GT) tool), and (2) analyses of results of PLifeCOVID-19 Online Studies conducted during the first and second wave of the pandemic. The conducted GT analysis and cross-sectional studies revealed that during the COVID-19 outbreak in March 2020, the interest in immune-related compounds and foods like vitamins C and D, zinc, omega-3, garlic, ginger, or turmeric, as well as their consumption increased. Improving immunity was the main reason behind the supplementation and changes in consumption of pro-healthy foods. GT analysis has shown these interests were positively correlated with the interest in COVID-19, but adversely with cumulative cases or deaths. Respondents tended to start supplementation during the first COVID-19 wave rather than the second one. Except for the role of vitamins D and C, zinc, and selenium in patients with deficiencies of those nutrients, there are no clear and convincing studies that support the role of DSs use in COVID-19 prevention and treatment in healthy, well-nourished individuals. Moreover, as the risk of elevated intake of some nutrients due to the popularity of DSs exists, effective education of consumers in rationale use of DSs and health-protecting behaviors against COVID-19 should be developed.

Novel Coronavirus

Following the outbreak of a novel coronavirus (SARS-CoV-2) associated with pneumonia in China (Corona Virus Disease 2019, COVID-19) at the end of 2019, the world is currently facing a global pandemic of infections with SARS-CoV-2 and cases of COVID-19. Since severely ill patients often show elevated methemoglobin (MetHb) and carboxyhemoglobin (COHb) concentrations in their blood as a marker of disease severity, we aimed to summarize the currently available published study results (case reports and cross-sectional studies) on MetHb and COHb concentrations in the blood of COVID-19 patients. To this end, a systematic literature research was performed. For the case of MetHb, seven publications were identified (five case reports and two cross-sectional studies), and for the case of COHb, three studies were found (two cross-sectional studies and one case report). The findings reported in the publications show that an increase in MetHb and COHb can happen in COVID-19 patients, especially in critically ill ones, and that MetHb and COHb can increase to dangerously high levels during the course of the disease in some patients. The medications given to the patient and the patient’s glucose-6-phospate dehydrogenase (G6PD) status seem to be important factors determining the severity of the methemoglobinemia and carboxyhemoglobinemia. Therefore, G6PD status should be determined before medications such as hydroxychloroquine are administered. In conclusion, MetHb and COHb can be elevated in COVID-19 patients and should be checked routinely in order to provide adequate medical treatment as well as to avoid misinterpretation of fingertip pulse oximetry readings, which can be inaccurate and unreliable in case of elevated MetHb and COHb levels in the blood.

Objectives: To analyze the role of pharmacists during the COVID-19 pandemic, to measure pharmacists’ attitude toward COVID-19 safety measures (wearing masks, wearing gloves, isolation shield, good hygiene, etc.), and explore their perspectives regarding a second wave of the virus. Methods: This cross-sectional online survey study was conducted in Jordan during the COVID-19 outbreak in July 2020 to discuss Jordanian pharmacists’ awareness of safety at their workplace during the COVID-19 outbreak, their sources of information, and their predictions for COVID-19 vaccination. Results: The participants (n = 311) were all pharmacists mostly aged between 23–30 years old (45%) and female (83%). The primary source of information about COVID-19 was social networking (38.9%). Pharmacists were committed to social distancing (86.5%) and wearing masks (76.2%). They expressed levels of agreement to their role in decreasing COVID-19 spread (94.2%) and correcting false information (94.5%); they expressed levels of expectation toward concern about a second COVID-19 wave (83%) that would be more severe than the previous one (43.4%). Pharmacists expected that an influenza vaccine might be helpful in decreasing severity and spread of the COVID-19 pandemic (56.9%). Pharmacists expected COVID-19 vaccine development within 6 months of administering our study survey (84.9%) and that vaccination might be effective in preventing COVID-19 (93%) infection. Conclusion: Pharmacists expressed positive roles on COVID-19 spread through exemplary actions, self-commitment to protection measures, and public health awareness. Social media as a source of health information should be cautiously investigated, and pharmacists should always refer to evidence-based sources. The role of pharmacists is particularly important for the upcoming era of COVID-19 vaccination administration and awareness.

Dyadic Model

A dyadic approach to studying relationship dynamics yields considerably more insights than examining each partner separately. Yet relatively little research has examined dyadic models of commitment, despite commitment being essential to relationship persistence. Accordingly, we tested a dyadic version of the investment model of commitment. In two cross-sectional studies of couples and one experiment, we tested the role of partner investments and perceived partner investments as novel antecedents of commitment. Studies 1 and 2 demonstrated that greater partner investments were related to greater levels of individuals’ commitment, while controlling for individuals’ own satisfaction with, investments in, and alternatives to the relationship. Study 3 revealed that partner-reported investments predicted commitment independent of perceived partner investments. The findings advance the investment model beyond the individual level, emphasizing the need to examine dyadic elements of relationships.

ABSTRACT Objective: systematic review with a meta-analysis of the prevalence of malaria relapse. Method: it consisted in a search for cross-sectional studies, carried out in three databases, without application of filters. A total of 1,924 articles were identified, selected based on eligibility criteria. The selection was made in pairs from the reading of the titles, abstracts and text. The meta-analysis was performed with a statistical program. Results: a sample of 1,308 patients with malaria, ranging from 70 to 586 patients in the study. Relapse was estimated at 0.47%, with a 95% confidence interval and 99.04% of squared i. In the included studies, the prevalence of relapse ranged from 17.00% to 92.85%. The result of the meta-analysis is considered relevant, despite the heterogeneity. Conclusion: relapse is a phenomenon that can contribute to the maintenance of the endemicity of malaria in the world and to introduce it in non-affected areas. In addition, there is the need for advancement in the production of knowledge regarding this disease, to qualify the research methods on prevalence.

Second Wave

Background: The expected second wave of the COVID-19 pandemic has started in various regions of the world. Public health experts warned that it could be as lethal as the first wave if people did not comply with self-protective measures. Currently, there is a gap in the literature on the relationship between peoples’ assessment of the effectiveness of community-based measures regarding adherence to self-protective behaviors for COVID-19 prevention and control. This study aimed to assess the role of the perceived effectiveness of community-based measures in adherence to self-protective behaviors during the COVID-19 pandemic. Methods: The cross-sectional online survey conducted from March 24 to June 22, 2020. The study sample Included 400 participants (49% male and 51% female) from the Kingdom of Saudi Arabia (KSA). The outcome measure was compliance to four self-protective behaviors i.e., "social distancing;" "wearing facemask;" "washing hands more frequently;" and "disinfecting surfaces in homes." We computed Chi-square statistics and odds ratios (ORs) using 95% confidence intervals (CIs). Results: The findings demonstrated that participants aged 25–34 years old were 25% less likely to comply with hand hygiene (OR = 0.75; 95% CI: 0.33–0.95) and social distancing (OR = 0.76; 95% CI: 0.34–0.98). Misconceptions related to COVID-19 significantly decreased compliance with self-protective behaviors by up to 27%. Participants who rated government decisions as useful were approximately 1.7 times more likely to comply with self-protective behaviors. Conclusion: Community-based measures should focus on engaging segments of the population That are currently less compliant. Health education policies should also focus on enhancing the perceived sense of control and personal responsibility and reduce anxiety levels. A continuous commitment to the implementation of preventive interventions and the clarification of misconceptions are required to combat the expected second wave.

Interface Science

The world of materials is a world of interfaces. Indeed many technologically significant materials have properties both physical and mechanical which are determined by the structure, composition, and bonding of the interfaces within these materials. Thus, electron microscopy and microanalysis, with its high resolution and specificity of information, is one of the key methods needed for characterization. Imaging can be done by amplitude contrast but is limited by the factor g • R (where R is a displacement vector), or resolution in phase contrast, and in today's modern instruments atomic arrangements can be imaged directly, both in plan and cross-sectional views. Beautiful examples are now being published. However so far, few developments to utilize this information for materials design have been forthcoming. On the other hand, interface or intergranular phases are very important in many metallurgical and ceramic systems. In fact many materials are composites of one kind or another and composites involving intergranular phases are an important group of such materials.

A cross-sectional survey study was designed to gather information on the use of dietary supplements by Spanish pediatricians. The study questionnaire was completed by 433 pediatricians (62% men, mean age 52.5 years) throughout the country. They also provided data on 10 of their patients (n = 4304) in which synbiotics, immune stimulants, and omega-3 polyunsaturated fatty acids (PUFAs) had been prescribed. Synbiotics were used by 92% of pediatricians, immune stimulants by 80.4%, and omega-3 PUFAs by 75.1%. Synbiotics were mainly used combined with antibiotics (92.6%) and for gastrointestinal disorders (91.2%), immune stimulants to enhance defenses and cold prevention (87.1%), and omega-3 PUFAs to improve symptoms of attention-deficit hyperactivity disorder (ADHD) (84.8%) and concentration (80.1%). Confidence and previous experience with the product (51.6%), composition and indications of the product (43.1%), and tolerability (39.9%) were main factors involved in decision-making. Children treated with omega-3 supplements were significantly older (mean age 7.6 (3.0) years) than those treated with synbiotics (3.9 (3.9) years) or immune stimulants (3.4 (2.8) years) (P<0.001). Short duration of treatment (<1 month) was significantly more common in the synbiotics group (90.5%), whereas longer duration of treatment (>3 months) was more frequent in the omega-3 group (79.1%). In the immune stimulants group, 60.4% of patients were treated for a period between 1 and 3 months. Clinical improvement was rated by participants as “a lot” in 39% of cases and as “quite” improvement in 50.6%. The overall level of satisfaction was rated as “very satisfied” by 52.1% of participants and as “quite satisfied” by 40.9%. The results show that the use of dietary supplements to improve different conditions, particularly minor disorders, is a widespread clinical practice among Spanish pediatricians. Administration regimens for the three types of supplements, synbiotics, immune stimulants, and omega-3 PUFAs, were consistent with guideline recommendations.

The Difference

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide longitudinal evidence for this developmental trend and to investigate how imitation of different kinds of target action steps contributes to inter-individual differences in overall imitation performance. The present analysis of longitudinal deferred imitation data contrasted toddlers’ imitation of functional and relevant (FURE) versus arbitrary and irrelevant (ARIR) target action steps at the ages of 18 and 24 months. The results show that the difference between the imitation rates of these two kinds of target action steps decreased with age, supporting the developmental trend from selective towards more exact imitation. In addition, findings of the present analyses point to the prominent role of toddlers’ imitation of arbitrary and irrelevant target action steps in shaping inter-individual variability of overall deferred imitation performance.

While considerable attention has been devoted to the personality traits of entrepreneurs, less attention has been given to their values, especially outside of a Western context. Values are instrumental in the decision to pursue entrepreneurship, and have implications for the entrepreneurʼs approach to creating and managing the venture. The role of values would seem especially relevant in the context of ethnic subcultures. Values traditionally associated with entrepreneurship, such as risk, individualism, competitiveness, wealth generation, and growth, may be more consistent with Western cultures, and may conflict with closely held values within various ethnic subcultures the world over. This article examines the values of entrepreneurs in two ethnic subcultures within South Africa. Findings are reported from interviews with cross-sectional samples of black and colored entrepreneurs. The results indicate entrepreneurs tend to embrace common values regardless of their individual ethnic heritage, but with different underlying patterns. In addition, the entrepreneurial path itself gives rise to certain shared values; and the overarching country culture has a strong influence on value orientations. Implications are drawn from the results, and suggestions made for ongoing research
