A Systematic Review on Curcumin and Anti-Plasmodium berghei Effects
Authors: Cheraghipour Kourosh , Shakib Pegah , Kalani Hamed , Ho Jeffery , Dolatshah Mehrdad , Amiri Sana
Published: March 2022

Background:

Turmeric (Curcuma longa L.) is a popular spice, containing curcumin that is responsible for its therapeutic effects. Curcumin with anti-inflammatory, antioxidant, anti-cancer, and antimicrobial activities has led to a lot of research focusing on it over the years. This systematic review aimed to evaluate researches on anti-Plasmodium berghei activity of curcumin and its derivatives.

Methods:

Our study was performed according to PRISMA guidelines and was recorded in the database of systematic review and preclinical meta-analysis of CAMARADESNC3Rs (SyRF). The search was performed in five databases, namely Scopus, PubMed, Web of Science, EMBASE, and Google Scholar from 2010 to 2020. The following keywords were searched: “Plasmodium berghei”, “Medicinal Plants”, “Curcumin”, “Concentration”, Animals kind”, “Treatment Durations”, “Routes of Administration” and “in vivo”.

Results:

Of the 3,500 papers initially obtained, 14 articles were reliable and were thus scrutinized. Animal models were included in all studies. The most commonly used animal strain were Albino (43%) followed by C57BL/6 (22%). The other studies used various murine strains, including BALB/c (14%) and ICR (7%). Two (14%) studies did not mention the strain of animal model used. Curcumin alone or in combination with other compounds depending on the dose used, route of administration, and animal model showed a moderate to strong anti-Plasmodium berghei effect.

Conclusion:

According to the studies, curcumin has anti-malarial effects on Plasmodium berghei and, however, its effect on human Plasmodium is unclear. Due to the side effects and drug resistance of current drugs in the treatment of human malaria, the use of new compounds with few or no side effects such as curcumin is recommended as an alternative or complementary treatment

Authors: Haumba Samson Malwa , Nhlabatsi-Khumalo Zanele Precious , Byarugaba Hugben , Ghebreyesus Yohannes , Dlamini Lindiwe Lizzie
Published: March 2022

Background:

The coronavirus disease 2019 (COVID-19) pandemic has spread with alarming speed, infecting millions globally, including Eswatini. Despite the institutionalization of measures by the Ministry of Health (MoH) to fight the pandemic, the cumulative number of people infected with COVID-19 has kept increasing daily. We sought to assess risk factors for COVID-19 infections among Health care workers (HCWs) in selected health facilities of the Lubombo region of Eswatini.

Methods:

A cross-sectional design and systematic stratified sampling were used to select the participants.

Results:

The study enrolled 333 HCWs, with the majority (201, 60.4%) being females, and the participants’ mean age was 33 years. The study showed that not having an isolation arrangement in a health facility for people suspected to have COVID-19 presents risk to HCWs for COVID-19 (Crude Odds Ratio (COR) = 2.5, 95%CI: 1.0–6.2), p = 0.50; Adjusted Odds Ratio (AOR) = 3.0, 95% confidence interval (CI) 1.0–8.7, p = 0.038). Likewise, HCWs who rarely followed infection prevention and control (IPC) measures were at higher risk of COVID-19 infection than those who followed such measures (COR = 4.2, 95%CI: 1.1–17.2, p = 0.041; AOR = 6.5, 95%CI: 1.4–30.0, p = 0.016), and HCWs exposed to a colleague diagnosed with COVID-19 were at higher risk of being infected themselves (AOR = 11.4; 95%CI: 0.9–135.7; p = 0.054).

Conclusion:

An active COVID-19 symptoms screening, triage and isolation arrangement for suspected COVID-19 clients for all clients entering the facility increases protection of HCWs from COVID-19. Reinforcement of all infection prevention and control measures to prevent exposures from infected patients and colleagues is essential.

Published: March 2022

The production and emission of fugitive dust is a topic ofconcern that Concrush brought to the MISG, 2020. Concrushis recycled concrete manufacturing company in the Hunterregion of New South Wales. Concrush's operations producefugitive dust, fine particles that can escape the site. Fugitive dust can travel long distances from the site ofemission, and can have negative health impacts includingrespiratory illnesses. Presently, concrete recyclingfacilities are managed by the Environmental ProtectionAgency using guidelines initially developed for the coalindustry. Concrush seeks to understand the appropriatenessof these guidelines, and how they can reduce and managefugitive dust on their Teralba site. Mathematical modellingof dust emission and transport, together with a review ofsimilar processes in the literature, identified a number ofpractical options for Concrush to reduce their dustemissions. In addition, opportunities for improved datacollection are identified.
Energy-efficient double belt press with integrated inductive heating system
Authors: Emonts Michael , Fischer Kai , Wigger Philipp , Greive Simon
Published: March 2022

At the Aachen Centre for Integrative Lightweight Production (AZL) of RWTH Aachen University a new double belt press with inductive heating and elastomer-coated pressure rollers has been developed and optimised within industrial AZL joint partner research projects. This machine system is patented by the AZL and available for industrial trials and also as commercial product in license. This new machine concept enables an efficient, continuous pressing process in a small installation space. The induction allows for a rapid heating of the steel belt material up to 300 °C and the elastomer pressure rollers enable surface contact during pressure application. The double belt press differs from conventional systems as it uses closed-loop controlled inductive heat input and high-temperature resistant elastomer-coated rollers for applying specific pressures up to 23 bar at maximum process temperatures up to 300 °C (current development for up to 400 °C). In extensive trials with several partners from the AZL partner network and external companies, the machine has proven to be efficient for consolidating thermoplastic composite laminates as well as for impregnating both thermoset and thermoplastic composite laminates.
The Effects of Using the Sun Safe App on Sun Health Knowledge and Behaviors of Young Teenagers: Results of Pilot Intervention Studies (Preprint)
Authors: Clare Isabelle M , Gamage Nisali , Alvares Gail A , Black Lucinda J , Francis Jacinta , Jaimangal Mohinder , Lucas Robyn M , Strickland Mark , White James , Nguyen Rebecca , Gorman Shelley
Published: March 2022

BACKGROUND

A balanced approach toward sun exposure and protection is needed by young people. Excessive sun exposure increases their risk for skin cancers such as melanoma, whereas some exposure is necessary for vitamin D and healthy bones. We have developed a new iOS smartphone app—Sun Safe—through a co-design process, which aims to support healthy and balanced decision-making by young teenagers (aged 12-13 years).

OBJECTIVE

The aim of this study was to test the capacity of Sun Safe to improve sun health knowledge and behaviors of young teenagers in 3 pilot intervention studies completed in 2020.

METHODS

Young teenagers (aged 12-13 years; N=57) were recruited through the web or through a local school via an open-access website and given access to Sun Safe (29/57, 51%) or a placebo (SunDial) app (28/57, 49%). Participants completed sun health questionnaires and knowledge quizzes before and after the 6-week intervention (either on the web or in class) and rated the quality of the app they used via a survey.

RESULTS

Of the 57 participants, 51 (89%) participants (26, 51% for placebo arm and 25, 49% for the Sun Safe arm) completed these studies, with most (>50%) reporting that they used a smartphone to access their designated app either “once a fortnight” or “once/twice in total.” Improved sun health knowledge—particularly about the UV Index—was observed in participants who were given access to Sun Safe compared with those who used the placebo (−6.2 [percentage correct] difference in predicted means, 95% CI –12.4 to –0.03; P=.049; 2-way ANOVA). Unexpectedly, there were significantly more sunburn events in the Sun Safe group (relative risk 1.7, 95% CI 1.1-1.8; P=.02; Fisher exact test), although no differences in time spent outdoors or sun-protective behaviors were reported. COVID-19 pandemic–related community-wide shutdowns during April 2020 (when schools were closed) reduced the time spent outdoors by >100 minutes per day (–105 minutes per day difference in predicted means, 95% CI –150 to –59 minutes per day; P=.002; paired 2-tailed Student t test). Sun Safe was well-rated by participants, particularly for information (mean 4.2, SD 0.6 out of 5).

CONCLUSIONS

Access to the Sun Safe app increased sun health knowledge among young teenagers in these pilot intervention studies. Further investigations with larger sample sizes are required to confirm these observations and further test the effects of Sun Safe on sun-protective behaviors.
Evaluating the Efficacy of a Guided and Unguided Internet-Based Self-help Intervention for Chronic Loneliness: Protocol for a 3-Arm Randomized Controlled Trial (Preprint)
Authors: Seewer Noëmi , Skoko Andrej , Käll Anton , Andersson Gerhard , Luhmann Maike , Berger Thomas , Krieger Tobias
Published: March 2022

BACKGROUND

Loneliness, or perceived social isolation, is prevalent in both the general population and clinical practice. Although loneliness has repeatedly been associated with mental and physical health, research on interventions that reduce loneliness effectively is still rather scarce.

OBJECTIVE

This study aims to evaluate the efficacy of a guided and an unguided version of the same internet-based cognitive behavioral self-help program for loneliness (SOLUS-D) for adults.

METHODS

A total of 250 participants will be randomly assigned to 1 of 2 intervention groups (SOLUS-D with guidance or SOLUS-D without guidance) or a wait-list control group (2:2:1 allocation ratio). Adult participants experiencing high levels of loneliness will be recruited from the general population. Individuals currently experiencing at least moderately severe depressive symptoms, an ongoing severe substance use disorder, previous or current bipolar or psychotic disorder, or acute suicidality will be excluded from the trial. Assessments will take place at baseline, 5 weeks (midassessment), and 10 weeks (postassessment). The primary outcome is loneliness assessed using the 9-item University of California, Los Angeles Loneliness Scale at the posttreatment time point. Secondary outcomes include depressive symptoms, symptoms of social anxiety, satisfaction with life, social network size, and variables assessing cognitive bias and social behavior. The maintenance of potentially achieved gains will be assessed and compared at 6 and 12 months after randomization in the 2 active conditions. Potential moderators and mediators will be tested exploratorily. Data will be analyzed on an intention-to-treat basis.

RESULTS

Recruitment and data collection started in May 2021 and are expected to be completed by 2022, with the 12-month follow-up to be completed by 2023. As of the time of submission of the manuscript, 134 participants were randomized.

CONCLUSIONS

This 3-arm randomized controlled trial will add to the existing research on the efficacy of loneliness interventions. Furthermore, it will shed light on the role of human guidance in internet-based treatments for individuals with increased levels of loneliness and the possible mechanisms of change. If SOLUS-D proves effective, it could provide a low-threshold, cost-efficient method of helping and supporting individuals with increased levels of loneliness.

Authors: Qiang Shuai , Li Feng Yong , Zhou Yu , Song Bao Qiang , Li Qiang
Published: March 2022

BACKGROUND

It is well recognized that labiaplasty is the most common procedure of female cosmetic genital surgeries. The literature examining the postoperative satisfaction is not yet robust and there lack of long-term follow up. It might be necessary to conduct statistics of these techniques so that the outcomes can be better discussed preoperatively. Herein, we develop a stand-alone system serve as a preoperative assessment resource based on a follow-up of 414 patients with reduction labiaplasty.

OBJECTIVE

The aim of the study was to introduce a system with which to assess the results of labiaplasty procedure preoperatively, and offer help and advice to the women and surgeons.

METHODS

A retrospective note follow-up of labiaplasty over 10 years from 2008 was performed, identifying all patients undergoing surgery for their labia minora hypertrophy. 414 respondents were identified with a median follow-up of 44.68 (SD=9.05) months. Mean age was 32.10 (SD=7.82) years. Patients who underwent resection to remove excess lateral labia minora were included. Clinical characteristics such as age, motivation, preoperative psychological distress, surgical technique and satisfaction were reviewed and recorded. The survey was conducted in telephone and the questionnaire was anonymous. And 90 types of outcomes had been identified in the database.

RESULTS

Satisfaction varied from different clinical characteristics. In the database of the outcome, we multiplied the data of satisfaction in different items to obtain the overall satisfaction rate. And set them as different level, which indicated higher or lower satisfaction. WEB Front-end Development Technology was applied to achieve the evaluation system to select corresponding conditions, meet what their patients need, and get possible surgical results preoperatively.

CONCLUSIONS

In this evaluation system, three main techniques of labiaplasty are recorded. Women can easily be informed in preoperative counseling about the data supporting the efficacy of these procedures. And for the operator, this program could also suggest which method is the best once confront a dilemma.

Published: March 2022

BACKGROUND

Online ethnography is making a unique contribution to people with chronic condition as a complement to offline ethnography. Besides, it is particularly well-suited to studying the complexities and contingencies of people with chronic condition in online culture. Consequently, there is a need to synthesize existing knowledge on research activities for online ethnography for people with chronic condition.

OBJECTIVE

This scoping review aimed to provide a map of existing evidence on online ethnography for people with chronic condition, focusing on the characteristics, contributions and implementation process and provide recommendations for the use of online ethnography in the future.

METHODS

We followed the scoping review methodologies developed by Arksey and O’ Malley and the Joanna Briggs Institute. After developing search strategies based on keywords, comprehensive searches were conducted in the PubMed, CINAHL，Embase, Scopus, PsycInfo database. We limited the search strategies to documents written in English and published January 1, 2000, and February 1, 2022. After removing duplicates, articles were screened at the title and abstract level and at the full text level by two independent reviewers. On reviewer extracted data, which were descriptively analyzed to map the existed knowledge.

RESULTS

After screening 2836 titles and abstracts and 51 full texts, 25 publications were included, dating from 2009 to 2022. Studies mainly came from America (9/25, 36.0 %), most articles were from online forum (10/25, 40.0 %), majority of included were passive observation (19/25, 76.0 %), 20% of topics were people with mental illness (5/25). Meanwhile, majority of articles did not report immersion process in detail (16/25, 64.0 %), 36.0 % accepted the institutional review board approval (9/36).

CONCLUSIONS

Through analysis of the current literature across fields, we were able to demonstrate
that online ethnography has high potential to explore deeper experience of people with chronic conditions that not easy to be investigated using traditional ethnography. The results can provide practical guidance for online healthcare for chronic diseases in a large range of fields. Researchers should determine the research type and map online community primarily. Although large heterogeneity of the immersion, data interpretation and analysis were noted, the immersion process in the online environment is insufficient. Additionally, we have observed there is no uniform standard for ethical issues. We therefore recommend preserving privacy and confidentiality of online users.

Authors: Suryani Tatik - , Fauzi Abu Amar , Nurhadi Mochamad
Published: March 2022

This study aims to validate the essential antecedents of brand image enhancement in the digital era, based on a schematic theory. This study involved 400 respondents from four capital cities in Java, Indonesia, which comprise Surabaya, Jakarta, Bandung, and Yogyakarta, based on a quota sampling technique. The findings indicate that the quality of websites and social media sites may have no direct effects on brand image; any effects are transmitted through a serial mediation of brand awareness and E-WOM. Explicitly, the effect of a website’s quality on brand image is fully mediated, while social media’s quality effect on brand image is partially mediated through brand awareness and E-WOM. This study extends the current literature related to SMEs’ brand image. Also, this study offers practical recommendations for several stakeholders interested in empowering SMEs, including the government, entrepreneurship-based universities, and the SMEs themselves, who are all seeking strategies to enhance brand image while utilizing digital platforms such as social media and websites.
Factors Affecting the Intention to Use E-Wallets during the COVID-19 Pandemic
Authors: Ming Kelvin Lee Yong , Jais Mohamad
Published: March 2022

The COVID-19 pandemic has reshaped the lifestyle of Malaysians. The government has introduced various incentives to encourage contactless transactions. Malaysia has also expe- rienced a spike in e-wallet transactions during the COVID-19 pandemic. However, there is no consensus on the reasons behind the rapid increase in the usage of e-wallets. This study aims to fill a knowledge gap by incorporating government support, the perceived risk, and social influence as the potential factors affecting the use of e-wallets. Survey data were collated from 598 respondents using Google Forms and analyzed using covariance-based structural equation modeling (CB-SEM). The findings confirm that perceived usefulness, government support, the perceived risk, and social influence are positively related to the attitude toward the usage of e-wallets. This attitude is also positively related with the user’s intention of using the wallets. The outcomes of this study may assist policymakers to devise effective strategies that are able to capture the users’ intentions to use e-wallets during the COVID-19 pandemic. This study also recommends that the government increases the incentives to speed up the formation of a cash- less society. The related organizations should also enhance public awareness on the usefulness of e-wallets in preventing virus transmission.

Published: March 2022

The mushrooming growth of luxury brands has been evidenced worldwide, especially among developing countries such as Malaysia. Despite Malaysian consumer confidence slowing due to uncertainty about the economic conditions, the demand for luxury brands is still expected to rise. Interestingly, a significant rise in the demand for luxury brands has been observed in the millennials group. This study examines the relationship of electronic word-of-mouth and the country of origin’s image on millennials' attitudes toward luxury brands and the intention to purchase luxury fashion brands. The study among 333 millennials revealed that the country of origin’s image has both direct and indirect effects on the intention to purchase luxury fashion brands. Electronic word-of-mouth (eWOM) was found statistically insignificant in explaining the intention to purchase, but eWOM had a significant relationship on intention to purchase through its mediation effect of the attitude toward luxury brands. Accordingly, the findings found support for the balance theory. The results also suggest that the owners of luxury brands should carefully manage the country of origin because it will affect the overall brand image, as perceived by consumers. Limitations and future directions of the study are also included at the end of the article.
