Published: September 2021

Abstract
To obtain a kind of superhydrophobic sponge with high oil and water selectivity, the MS/TiO2/PDMS sponge was prepared via a two-step hydrophobic fabrication based on the melamine sponge (MS), tetrabutyl titanate (TBOT), and polydimethylsiloxane (PDMS). The effects of modification time, the concentrations of TBOT and PDMS on the properties of the MS/TiO2/PDMS sponge were studied, and the separation mechanism was also discussed based on the interaction between the oil and the surface of the MS/TiO2/PDMS sponge. The results suggest that under optimal conditions, the MS/TiO2/PDMS sponge show superhydrophobicity. The contact angle and adsorption capacity for oil of the MS/TiO2/PDMS sponge are 149.2° and 98.5 g·g−1, respectively, and they can be recycled for about 25 cycles after oil–water separation test. This study prepares a new composite material with high oil–water selectivity, which is a good foundation for the development and research of new oil adsorbents.

Anápolis constitui-se como centro de crescente fluxo de mercadorias, pessoas e informações, tendo potencialidade para promover elementos locais como atrativos turísticos, o que implica investimento na oferta turística. O presente artigo tem como principal objetivo a análise da distribuição espacial e da qualificação da oferta de hospedagem de Anápolis (Goiás). Desse modo, apresenta a cartografia da oferta de hospedagem de Anápolis, contemplando a identificação dos objetos técnicos que compõem os meios de hospedagem e a participação das diferentes categorias na oferta de hospedagem. Para isso, realizou-se levantamento bibliográfico; levantamento de bases cartográficas; compilação de dados sobre a infraestrutura de hospedagem; georreferenciamento da hospedagem; elaboração, análise e interpretação de mapas temáticos com subsídio do software ArcGIS 10.2.2. Identificou-se que Anápolis conta com 27 meios de hospedagem, que se dividem em três categorias: Hotéis, Pousadas e Flat/Apart-hotel. Os hotéis se sobressaem quanto ao número de estabelecimentos e na oferta de leitos, seguidos das pousadas e do flat/Apart-hotel. Os estabelecimentos, em sua maioria, são de baixa qualificação, sendo 81% deles estão classificados com uma ou duas estrelas. Os estabelecimentos concentram-se na área central da cidade e sua dispersão acompanha a principal avenida de Anápolis (Avenida Brasil). Há um número maior de estabelecimentos que ofertam entre 16 e 79 vagas de leitos; somente a categoria dos hotéis apresenta disponibilidade acima de 113 leitos. Conclui-se que há necessidade de um planejamento turístico em Anápolis atento à oferta de hospedagem da cidade, no sentido de promover a diversidade de categorias de estabelecimentos e qualificação dos empreendimentos.

Hemozoin (beta-hematin) Formation Inhibitors: Promising Target for the
Development of New Antimalarials: Current Update and Future Prospect
Authors: Mali Suraj N. , Pandey Anima 
Published: September 2021

Background:
Malaria is responsible for social and economic burden in most lowincome
malaria-affected countries. Thus, newer antimalarials are needed to tackle morbidities and
mortalities associated with the drug-resistant malarial strains. Haemoglobin digestion inside the
food vacuole of malarial parasite would lead to producing redox-active and toxic-free heme. The
detoxification process adopted by Plasmodium sp. would give rise to hemozoin (Hz) (betahematin)
formation. Targeting the pathway of hemozoin formation is considered a validated target
for the discovery of newer antimalarials.

Objective:
This study aims to collect detailed information about aspects of hemozoin (Hz) (betahematin)
inhibitors.

Methods:
A systemic search has been carried out using PubMed, Google Scholar, CNKI, etc., for
relevant studies having the keyword, 'hemozoin or beta-hematin' for almost the last 2 decades
(2000-2021).

Results:
This review tries to summarize all the recent advancements made for the developments of
synthetic, natural isolated phytoconstituents and plant extracts inhibiting the hemozoin (betahematin)
formation.

Conclusion:
Thus they would act as promising antimalarial candidates in the near future.

The design of this study is a quasi-experimental. The sample used in this study was eight respondents with certain criteria. Treat physical activity twice on different days with 4 measurements of uric acid levels. The method of this study is repeated measure analysis. When subjects are measured repeatedly, requiring fewer subjects per experiment, then repeated measures analysis can be used. The results showed that the treatment of badminton had a significant effect on changes in uric acid levels with a probability value of 0,038. These results were obtained by using the Greenhouse-Geisser test where the assumptions of normality and homogeneity were satisfied. From the marginal test results using pairwise comparisons, there was a significant difference in the average uric acid levels at 15 minutes after exercise and 9 hours the following day, where there was a decrease of 1.169 mg/dl. Badminton can reduce uric acid levels, which is indicated by a decrease of 0.15 mg/dl at 09.00 the next day compared to before exercise. Marginally, this decrease is not statistically significant, but regular badminton can be an option for physical activity for those who want to reduce uric acid levels.
The Impact of Patient Characteristics on Their Attitudes Toward an Online Patient Portal for Communicating Laboratory Test Results: Real-World Study
Authors: Tossaint-Schoenmakers Rosian , Kasteleyn Marise , Goedhart Annelijn , Versluis Anke , Talboom-Kamp Esther 
Published: September 2021

Background
Patient portals are promising tools to increase patient involvement and allow them to manage their health. To optimally facilitate patients, laboratory test results should be explained in easy language. Patient characteristics affect the usage of portals and the user satisfaction. However, limited research is available, specified for online communicating laboratory test results, on whether portal use and acceptance differ between groups.

Objective
The aim of this study was to assess the effect of patient characteristics (gender, age, education, and chronic disease) on the self-efficacy and perceived usability of an online patient portal that communicates diagnostic test results.

Methods
We used the online-administered eHealth impact questionnaire (eHIQ) to explore patients’ attitudes toward the portal. Patients visiting the portal were asked to complete the questionnaire and to answer questions regarding gender, age, education, and chronic disease. The subscale “information and presentation” of the eHIQ assessed the usability of the patient portal and the subscale “motivation and confidence to act” assessed self-efficacy to determine whether patients were motivated to act on the presented information. Age, gender, education, and chronic disease were the determinants to analyze the effect on usability and self-efficacy. Descriptive analyses were performed to explore patient characteristics, usability, and self-efficacy. Univariable and multivariable regression analyses were performed with age, gender, education, and chronic disease as determinants, and usability and self-efficacy as outcomes.

Results
The questionnaire was completed by 748 respondents, of which 428 (57.2%) were female, 423 (56.6%) were highly educated, and 509 (68%) had no chronic disease. The mean age was 58.5 years (SD 16.4). Higher age, high education, and asthma or chronic obstructive pulmonary disease were significant determinants for decreased usability; respectively, b=-.094, 95% CI -1147 to 0.042 (P<.001); b=-2.512, 95% CI -4.791 to -0.232 (P=.03); and b=-3.630, 95% CI -6.545 to -0.715 (P=.02). High education was also a significant determinant for a lower self-efficacy (b=-3.521, 95% CI -6.469 to -0.572; P=.02). Other determinants were not significant.

Conclusions
This study showed that the higher-educated users of a patient portal scored lower on usability and self-efficacy. Usability was also lower for older people and for patients with asthma or chronic obstructive pulmonary disease. The results portal is not tailored for different groups. Further research should investigate which factors from a patient’s perspective are essential to tailor the portal for different groups and how a result portal can be optimally integrated within the daily practice of a doctor.
Depression, Anxiety, and Daily Activity Among Adolescents Before and During the COVID-19 Pandemic: Cross-sectional Survey Study
Authors: Jolliff Anna , Zhao Qianqian , Eickhoff Jens , Moreno Megan 
Published: September 2021

Background
The COVID-19 pandemic has resulted in significant changes to adolescents’ daily lives and, potentially, to their mental health. The pandemic has also disproportionately affected historically marginalized and at-risk communities, including people of color, socioeconomically disadvantaged people, people identifying as female, and youth.

Objective
This study aimed to understand differences in depression and anxiety among 2 groups of adolescents in the United States before and during the COVID-19 pandemic, and to examine demographic and daily activity variables associated with depression and anxiety.

Methods
Online surveys were distributed in 2019 and 2020. Demographic questions were asked at the time of enrollment, and included participants’ age, gender, race and ethnicity, and socioeconomic status (SES). The 8-item Patient Health Questionnaire was used to assess symptoms of depression, and the 7-item Generalized Anxiety Disorder scale was used to assess symptoms of anxiety. A total of 4 pandemic-specific daily activity questions were asked only of the pandemic group. Analyses of covariance compared depression and anxiety between prepandemic and pandemic groups. Demographic and lifestyle variables were included as covariates.

Results
The sample comprised a total of 234 adolescents, with 100 participants in the prepandemic group and 134 participants in the pandemic group. Within the pandemic group, 94% (n=126) of adolescents reported being out of school due to the pandemic, and another 85.8% (n=115) and 57.1% (n=76) were prevented from extracurricular activities and exercise, respectively. Higher depression was seen in the pandemic group, with a least-squares adjusted mean of 7.62 (SD 1.36) compared to 6.28 (SD 1.42) in the prepandemic group, although the difference was not significant (P=.08). There was no significant difference in anxiety scores between the 2 groups (least-squares adjusted means 5.52, SD 1.30 vs 5.01, SD 1.36; P=.48). Within the pandemic group, lower SES was predictive of anxiety, such that those in the pandemic group of lower SES were more anxious than their higher-SES peers (least-squares adjusted means 11.17, SD 2.34 vs 8.66, SD 2.16; P=.02). Within the pandemic group, being out of work or school and not partaking in extracurricular activities or exercise due to the pandemic were not associated with higher depression or anxiety scores.

Conclusions
In this study, neither being in the pandemic group nor experiencing changes in daily activity due to the pandemic was associated with higher depression or anxiety. However, we found that adolescents from lower SES backgrounds experienced significantly more anxiety during the pandemic than their more privileged peers. Both instrumental and mental health interventions for low-income adolescents are imperative.
Influence of Mass Media on Italian Web Users During the COVID-19 Pandemic: Infodemiological Analysis
Authors: Rovetta Alessandro , Castaldo Lucia 
Published: September 2021

Background
Concurrently with the COVID-19 pandemic, the world has been facing a growing infodemic, which has caused severe damage to economic and health systems and has often compromised the effectiveness of infection containment regulations. Although this infodemic has spread mainly through social media, there are numerous occasions on which mass media outlets have shared dangerous information, giving resonance to statements without a scientific basis. For these reasons, infoveillance and infodemiology methods are increasingly exploited to monitor information traffic on the web and make epidemiological predictions.

Objective
The purpose of this paper is to estimate the impact of Italian mass media on users’ web searches to understand the role of press and television channels in both the infodemic and the interest of Italian netizens in COVID-19.

Methods
We collected the headlines published from January 2020 to March 2021 containing specific COVID-19–related keywords published on PubMed, Google, the Italian Ministry of Health website, and the most-read newspapers in Italy. We evaluated the percentages of infodemic terms on these platforms. Through Google Trends, we searched for cross-correlations between newspaper headlines and COVID-19–related web searches. Finally, we analyzed the web interest in infodemic content posted on YouTube.

Results
During the first wave of COVID-19, the Italian press preferred to draw on infodemic terms (rate of adoption: 1.6%-6.3%) and moderately infodemic terms (rate of adoption: 88%-94%), while scientific sources favored the correct names (rate of adoption: 65%-88%). The correlational analysis showed that the press heavily influenced users in adopting terms to identify the novel coronavirus (cross-correlations of ≥0.74 to ≤0.89, P value <.001; maximum lag=1 day). The use of scientific denominations by the press reached acceptable values only during the third wave (approximately 80%, except for the television services Rai and Mediaset). Web queries about COVID-19 symptoms also appeared to be influenced by the press (best average correlation=0.92, P<.007). Furthermore, web users showed pronounced interest in YouTube videos of an infodemic nature. Finally, the press gave resonance to serious “fake news” on COVID-19, which caused pronounced spikes of interest from web users.

Conclusions
Our results suggest that the Italian mass media have played a decisive role in spreading the COVID-19 infodemic and addressing netizens’ web interest, thus favoring the adoption of terms that are unsuitable for identifying COVID-19. Therefore, the directors of news channels and newspapers should be more cautious, and government dissemination agencies should exert more control over such news stories.
