RESUMO
BACKGROUND: Prostate cancer screening is a crucial preventive element for improving the survival rates of prostate cancer. Therefore, our research objective was to investigate the effect of health belief model-based education on prostate cancer knowledge, health beliefs, and preventive health practices among adult and older adult males. METHODS: A one-group pre-test/post-test quasi-experimental study design was carried out at the one-day outpatient clinics affiliated to General Alexandria Main University Hospital. We enrolled 110 men aged 45-75 years old in a health belief model-based educational intervention program. Various questionnaires were utilized to gather data before, immediately after, and three months following the intervention. These questionnaires included the socio-demographic questionnaire, Prostate Cancer Knowledge Questionnaire (PCKQ), Prostate Cancer Screening-Health Belief Model Scale (HBM-PCS), Prostate Cancer Preventive Practices Questionnaire (PCPPQ), and one question regarding the intention to undergo PC screening. RESULTS: Participants' knowledge about prostate cancer screening improved significantly immediately after the program and this positive change was maintained at the follow-up (p = 0.000). Furthermore, participants' perceptions and preventive practices towards prostate cancer screening had changed significantly after program completion and at follow-up (p = 0.000). After program completion, many of the participants (92.7%) expressed their intention to undergo prostate cancer screening within the coming six months (p = 0.000). The younger age group (45-49 years) showed higher scores in their perception of prostate screening (p = 0.001). Higher education and income were significantly associated with higher scores in the three scales (p = 0.000 in all scales). CONCLUSION: The study findings emphasized the effectiveness of the designed health educational program based on the HBM on PC preventive behaviors, through significantly improving participants' knowledge level, perceptions, practices, and intentions to PC screening. The program is highly recommended for prostate cancer preventive health practices among both adult and older adult males.

OBJECTIVES: A significant gap currently exists in the availability of reliable and scientifically rigorous measures for evaluating resilience among older Arabic-speaking populations. The primary objective of this study was to assess the psychometric properties of an Arabic adaptation of the 15-item Resilience Scale of Older Adults (RSOA) in a sample of Arabic-speaking Egyptian older adults. METHOD: Using a cross-sectional design and a convenience sample of 539 Egyptian older adults, with 60.7% aged between 65 and 75 years (50.3% females), participants completed an online Google form-based anonymous questionnaire, including sociodemographic information, the RSOA, and the 10-item CD-RISC. To ensure accurate translation, the forward-backward translation method was employed. Confirmatory factor analysis (CFA) and gender invariance in the RSOA were analyzed. McDonald's ω and Cronbach's α were calculated to assess internal consistency. RESULTS: The results demonstrate that the Arabic RSOA and its subscales exhibit high internal consistency, with McDonald's ω and Cronbach's α values ranging from 0.83 to 0.93. CFA analysis revealed that the four-factor model fit of RSOA was acceptable. Measurement invariance was supported across genders. Furthermore, both genders exhibited no significant differences in all four RSOA dimensions. Convergent validity was supported by demonstrating that the four RSOA sub-scores and total scores correlated positively and significantly with the 10-item CD-RISC. CONCLUSION: While further cross-cultural validation involving other Arab countries and communities is necessary, this study suggests that the Arabic RSOA may be used to measure resilience among broader Arabic-speaking older adults in clinical and research contexts.
RESUMO
BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease that influences numerous body systems. Furin, tristetraprolin (TTP), and NOD, LRR, and pyrin domain-containing protein 3 (NLRP3) contribute in developing autoimmune illnesses. AIM: Understandthe role of furin, TTP, and NLRP3 mRNA gene expression in SLE pathogenesis and prognosis. Methods: Total 210 individuals were enrolled, divided in two group: cases and control; 105 participants in each group. Real-time quantitative PCR for furin, TTP,and NLRP3 mRNA gene expression were determined for each subject. RESULTS: SLE patients showed significantly higher serum furin [median 20.10 (0.0-162.88) in comparison with control group [median 1.10 (0.33-8.64)] with significant pvalue (p < 0.001), for NLRP3 expression [median 7.03 (0.0-282.97) compared to control group [median 1.0 (0.44-9.48)] with significant p value (p = 0.006)but lower TTP [median 2.37 (0.0-30.13)] in comparison with control group [median 7.90 (1.0-29.29)] with significant p value (p < 0.001) . Elevated levels of Furin and NLRP3 and low levels of TTP were linked to increased illness activity. CONCLUSION: Furin and NLRP increase in SLE and higher with illness activity. TTP is lowerin SLE and negatively correlates with disease activity.

Hashimoto's thyroiditis (HT) and Graves' disease (GD) susceptibility depends on a complex interaction between environmental and genetic factors. Genes for tumor necrosis factor alpha (TNF-α) and toll-like receptors (TLRs) have been incorporated into the pathophysiology of autoimmune disorders. Our aim is to assess the association between TLR7 (rs179009) and TNF-α (rs1800629) polymorphisms and susceptibility to autoimmune thyroid disorders. One-hundred ninety-nine individuals, divided into 68 HT patients in group I, 57 GD patients in group II, and 74 age- and gender-matched healthy subjects in group III, underwent laboratory investigations, including the detection of TLR7 and TNF-α polymorphisms using real-time PCR technique. TLR7 (rs179009) genotypes, A/G and G/G, were significantly more prevalent in HT patients (group I) compared to normal controls. Meanwhile, TNF-α (rs1800629) genotypes in GD patients (group II) showed a six fold increase in the risk of the disease in the G/A and A/A genotypes. Our findings propose the fact that the polymorphisms of TLR7 (rs179009) play a role in the susceptibility and the development of Hashimoto's thyroiditis, whereas TNF-α (rs1800629) polymorphisms play a role in the susceptibility and development of Graves' disease.

Placenta Accreta Spectrum (PAS) is a life-threatening condition in which placental trophoblastic cells abnormally invade the uterus, often up to the uterine serosa and, in extreme cases, tissues beyond the uterine wall. Currently, there is no clinical assay for the non-invasive detection of PAS, and only ultrasound and MRI can be used for its diagnosis. Considering the subjectivity of visual assessment, the detection of PAS necessitates a high degree of expertise and, in some instances, can lead to its misdiagnosis. In clinical practice, up to 50% of pregnancies with PAS remain undiagnosed until delivery, and it is associated with increased risk of morbidity/mortality. Although many studies have evaluated the potential of fetal biomarkers circulating in maternal blood, very few studies have evaluated the potential of circulating placental extracellular vesicles (EVs) and their miRNA contents for molecular detection of PAS. Thus, to purify placental EVs from maternal blood, we customized our robust ultra-sensitive immuno-purification assay, termed EV-CATCHER, with a monoclonal antibody targeting the membrane Placental Alkaline Phosphatase (PLAP) protein, which is unique to the placenta and present on the surface of placental EVs. Then, as a pilot evaluation, we compared the miRNA expression profiles of placental EVs purified from the maternal plasma of women diagnosed with placenta previa (controls, n = 16); placenta lying low in uterus but not invasive) to those of placental EVs purified from the plasma of women with placenta percreta (cases, n = 16), PAS with the highest level of invasiveness. Our analyses reveal that miRNA profiling of PLAP+ EVs purified from maternal plasma identified 40 differentially expressed miRNAs when comparing these two placental pathologies. Preliminary miRNA pathway enrichment and gene ontology analysis of the top 14 upregulated and top nine downregulated miRNAs in PLAP+ EVs, purified from the plasma of women diagnosed with placenta percreta versus those diagnosed with placenta previa, suggests a potential role in control of cellular invasion and motility that will require further investigation.

This randomized controlled trial evaluated the effectiveness of a 12-week home-based transitional cardiac telerehabilitation (Hb-T-CTR) program on health-related quality-of-life and therapeutic self-care in older adults' post-Coronary Artery Bypass Grafting (CABG). The intervention group (n = 57) underwent Hb-T-CTR, incorporating preoperative counseling, postoperative education, a culturally adapted video, home visits, and telephone counseling, while the control group (n = 61) received standard care. Using the Coronary Revascularization Outcome Questionnaire and the Sidani Doran Therapeutic Self-Care Measure, data were collected at three time points. Results showed significant improvements in overall scores for both health-related quality of life (t1=3.386, P = 0.001; t2=4.224, P < 0.001) and therapeutic self-care (t1=7.104, P < 0.001; t2=4.242, P < 0.001) in the intervention group compared to controls. This telehealth approach provides convenient and accessible rehabilitation services for older adults' post-CABG and highlights the importance of integrating Hb-T-CTR into routine care for personalized rehabilitation. This study underscores the potential of telehealth tools in overcoming barriers and enhancing patient-centered interventions.
RESUMO
BACKGROUND: The global aging population necessitates leveraging technology for older adults' independence and mental well-being. Gerontechnology, tailored for older users, thrives when accessible and accepted, with the pivotal role of acceptance of change shaping its adoption. AIMS: This study investigates the mediating role of acceptance of change in the relationship between gerontechnology acceptance and mental well-being among older adults and explores disparities in urban and rural settings DESIGN & METHODS: A cross-sectional, correlational design adhering to STROBE guidelines collected data through an interview survey from 802 older adults. Instruments included the Older Adult Structured Survey, Short Version of Senior Technology Acceptance, Acceptance of Change Scale, and the World Health Organization Well-Being Index. RESULTS: The results underscore a significant correlation between technology adoption, adaptability, and mental well-being among 60-year-olds and older. Notably, an individual's openness to change significantly influences the technology-mental well-being relationship, emphasizing its impact on overall health. Urban areas exhibit a stronger positive correlation between technology acceptance and mental well-being, whereas rural regions demonstrate a more pronounced negative correlation. CONCLUSION: This research contributes valuable knowledge for addressing the unique challenges older adults face in diverse geographic settings, paving the way for targeted and effective initiatives. IMPLICATIONS: Nurses should prioritize understanding the nexus between gerontechnology acceptance, change adaptability, and mental wellness, integrating technology education and culturally sensitive interventions to enhance care strategies for older adults in diverse geographic settings. This study lays the groundwork for developing person-centered geriatric nursing care plans, underscoring the importance of harnessing technology for improved mental well-being.

AIM: The COVID-19 pandemic caused drastic changes in older people's daily activities with a negative impact on their mental health, yet older people are less likely to seek mental health services. This study aims to explore the relationship between knowledge of and familiarity with mental health services, along with the impact of the COVID-19 pandemic, and barriers to seeking mental health services among older people. METHODS: A descriptive cross-sectional study was conducted with a convenience sample of 352 older people, recruited among community-dwelling adults who attended randomly selected postal offices and pension outlets. Three tools were used: a structured interview schedule for sociodemographic and clinical characteristics of older people, the revised version of the Knowledge and Familiarity of Mental Health Services Scale (KFFMHS-R), and the Barriers to Mental Health Services Scale Revised (BMHSS-R). RESULTS: All participants reported experiencing mental health distress during the COVID-19 pandemic. Intrinsic barriers had a higher mean score than extrinsic barriers, and 27.4% of the variance of overall barriers to seeking mental health could be explained through regression analysis by familiarity, knowledge of mental health services, and age. Overall barriers explained 24.4% of the variance of older people's perceived distress as an impact of the COVID-19 pandemic (F = 22.160, P < 0.001). CONCLUSIONS: Knowledge of mental health services was the most significant predictor of barriers to seeking mental health services during the COVID-19 pandemic. Higher barriers predicted higher distress as an impact of the COVID-19 pandemic. The results of the study suggest the need for a multidisciplinary mental health team for older people.

BACKGROUND: COVID-19 is a novel infectious disease for which no specific treatment exists. It is likely that a combination of genetic and non-genetic factors predispose to it. Expression levels of genes that are involved in the interaction with SARS-CoV-2 or the host response are thought to play a role in disease susceptibility and severity. It is crucial to explore biomarkers for disease severity and outcome. Herein, we studied the expression levels and effects of long non-coding metastasis-associated lung adenocarcinoma transcript 1 (lnc-MALAT1) and long non-coding maternally expressed gene 3 (lnc-MEG3) in COVID-19 patients. The study enrolled 35 hospitalized and 35 non-hospitalized COVID-19 patients, and 35 healthy controls. A chest computed tomography (CT) scan, complete blood count (CBC), ferritin, C-reactive protein (CRP), D-dimer and analysis of lnc-MALAT1 and lnc-MEG3 expression were done. RESULTS: There was a significant relation between ferritin, CRP, D-dimer levels, oxygen saturation, CT-CORADS score and disease severity. Lnc-MALAT1 was significantly higher but lnc-MEG3 was significantly lower in patients vs. controls, and in hospitalized vs. non-hospitalized patients. Elevated MALAT1 and reduced MEG3 levels were significantly associated with more elevated ferritin, CRP, D-dimer levels, lower oxygen saturation, higher CT-CORADS score and poor survival. Moreover, MALAT1 and MEG3 levels displayed higher sensitivity and specificity as predictors of COVID-19 severity compared with other prognostic biochemical markers such as ferritin, CRP, and D-dimer. CONCLUSIONS: MALAT1 levels are higher, whereas MEG3 levels are lower in COVID-19 patients. Both are linked to disease severity and mortality and could emerge as predictive biomarkers for COVID-19 severity and therapeutic targets.

In 2020, COVID-19 was the third leading cause of death among individuals between the ages of 45-84 years (Woolf 325:123-124, 2021). However, systemic inequities and disparities exacerbated the pandemic's effect on racial and ethnic groups (Tai 72:703-706, 2021). The exact impact of the pandemic within the Middle Eastern North African (MENA) community is not well documented or understood due to the lack of federal recognition of MENAs as an ethnic group. Given the lack of COVID-19 research among this community, this study was created to address COVID-19 needs, perceptions, and health-seeking behaviors regarding COVID-19 precautions, mask wearing, and routine healthcare appointments. Between June and July 2020, an anonymous survey was distributed in English and Arabic using a Community Participatory Based Research design in Dearborn, Michigan. Overall, 298 individuals were surveyed and their misconceptions regarding COVID-19 infections, spread, and precautions were identified. It is important to note that about 75% of survey respondents identified as female, while only 24% of survey participants identified as male. Survey participants slightly underestimated the distance in which COVID-19 can be transmitted as 5.5 ± 3.5. Participants severely underestimated COVID-19 deaths in the US, with 23% estimating that under 250,000 individuals would die from COVID-19. Overall, 60% of participants reported that they did not have any difficulty adhering to COVID-19 precautions and self-quarantine rules during Ramadan, while this number dropped to only 36% (87/238) after Ramadan. The goal of this study was to serve as a tool to better understand the misconceptions, difficulties, and needs regarding COVID-19 among this understudied population. The MENA community may be particularly vulnerable to the economic, medical, and social changes brought about by the COVID-19 pandemic.

PURPOSE: This study aims to evaluate the health-related quality of life (HRQoL) for children as well as parents' satisfaction 5-7 years after transanal pull-through operation of Hirschsprung's disease. METHODS: The PedsQL™ 4.0-Core Measurement Model-and the PedsQL™ 3.0 Healthcare Satisfaction Generic Module were used to evaluate the quality of life and parents' satisfaction, respectively. Parents of 53 children who were operated by transanal pull-through operation 5-7 years earlier were included in the study. RESULTS: The HRQoL of children was generally good. The mean scores were 87.3, 95.5, 92.3 and 93.2 % for physical, emotional, social and school functioning, respectively. Overflow incontinence was significantly affecting physical (ß = -.261), emotional (ß = -.299), social (ß = -.42) and school functioning (ß = -.534). Constipation significantly affected emotional (ß = -.742), social (ß = -.108) and school (ß = -.282) functioning. Failure to thrive was significantly affecting social (ß = -.215) and school functioning (ß = -.176). Age at time of surgery was affecting physical, emotional, social and school functioning (ß = -.686, -.627, -.865 and -.907, respectively). Parents were generally satisfied from the healthcare service with an overall satisfaction of 90.7 with the least satisfaction (79.8) in family inclusion category. CONCLUSIONS: Transanal pull-through operation disease showed a good postoperative long-term HRQoL. Overflow incontinence and age at time of surgery had a significant negative effect on all the aspects of children's HRQoL. Parental satisfaction was good and could be improved by more family inclusion.

Background: Oral mucositis is a common and distressing side effect of head and neck oncology treatment. Photobiomodulation therapy can be utilized to prevent and treat oral mucositis. Its impact on salivary cytokines has yet to be thoroughly investigated. This is the first systematic review aiming to evaluate the effect of photobiomodulation on salivary cytokines in patients undergoing anticancer treatment. Methods: Numerous data resources, from the Web of Science, Embase, ScienceDirect, PubMed, Cochrane Library, and Scopus were sought. Articles published up until February 2024 were included if they met the following inclusion criteria: clinical trials reporting the effect on salivary cytokines in patients undergoing anticancer therapy. The methodological quality was assessed using several appraisal tools. Results: Four studies were deemed eligible for inclusion. All the studies were conducted in Brazil and used an InGaAlP diode laser with a wavelength of 660 nm. The included studies had a relatively low risk of bias. The head and neck cancer patients' salivary cytokines that were assessed by the studies, along with photobiomodulation therapy, included IL-12p70, TNF-α, IL-6, IL-8, IL-10, CXCL8, and IL-1ß. The results varied among the studies. Conclusions: Our results show that photobiomodulation demonstrated positive results for reducing the severity of OM in all the included studies. Among the examined salivary cytokines, IL-6 is the most relevant cytokine for oral mucositis development and severity. A variation in the cytokine levels between the studies was noted due to differences in the type of anticancer treatment and saliva sampling.
RESUMO
Background Although dental implants have demonstrated very high success rates, they are susceptible to complications such as peri-implantitis that can lead to failure. Methods Twenty implants with surfaces grit-blasted using hydroxyapatite and acid-etched were randomly divided into four groups (five in each group). Three groups were assigned to laser treatments: Group I (erbium, chromium-doped: yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser), Group II (650-nm diode laser), and Group III (808-nm diode), and one control group, Group IV. The surface roughness parameters (roughness average(Ra) and root mean square roughness(Rq)) were measured using a non-contact optical profilometer and scanning electron microscope to evaluate the surface topography after the laser treatments. Results Significant differences were observed between the laser groups regarding the surface roughness Ra (3.56±0.26, 3.45±0.19, 3.77±0.42, pc=0.0004, pe=0.0002, pf=0.001) and Rq values (4.49±0.34, 4.35±0.26, 4.72±0.56, pc=0.0007, pe=0.0006, pf=0.002) and the control group (2.81±0.10; 3.57±0.19). However, no significant difference was observed between the different laser treatment modalities. The scanning electron microscope images revealed some morphological changes on the implant surfaces following laser treatment, but no melted morphology was observed. Conclusions The application of Er,Cr:YSGG, 650-nm diode laser, and 808-nm diode did not show melting changes on implant topography. However, some increase in surface roughness was detected. Further studies are recommended to assess the effectiveness of these laser settings on bacterial reduction and osseointegration.
RESUMO
Background: Given the suffering experienced by cancer patients, effective solutions must be found to prevent the most painful and debilitating side effects of anticancer treatment. The use of photobiomodulation (PBM) with specific parameters has been proposed to prevent oral mucositis in adults undergoing hematopoietic stem cell transplantation as well as in head and neck cancer patients receiving radiotherapy alone without chemotherapy. No recommendations were possible for patients undergoing chemotherapy alone. This systematic review aims to analyze the effectiveness of preconditioning by PBM in preventing chemotherapy-induced oral mucositis. Methods: This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA, Checklist and registered at the International Prospective Register of Systematic Reviews (PROSPERO). We searched and identified articles of the subsequent bibliographic databases: PubMed and Cochrane. Revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) was used to assess the risk of bias of studies included in this review. Results: There were only six clinical trials examining the efficacy of PBM therapy in the primary prevention of chemotherapy-induced oral mucositis. All of the studies used lasers, except for one study that compared lasers with light-emitting diodes. The wavelength ranges from 630 to 830 nm. Irradiation parameters varied among the included studies. All studies showed good results for the use of PBM in the prevention of oral mucositis except for one study that found no benefit for the laser application. Conclusions: PBM has been shown to be effective in preventing oral mucositis when applied to healthy tissues. Finding the optimal protocol has been difficult due to the variability between studies, and therefore, further well-designed, controlled, blinded studies are recommended to precisely determine irradiation parameters and the number of sessions. This review has been registered at the International Prospective Register of Systematic Reviews (PROSPERO) under number CRD42023397771.

Background: This systematic review aims to analyze the effectiveness of the association of photodynamic therapy (PDT) and photobiomodulation (PBM) in the treatment of recurrent herpes labialis and to analyze the very many variables of parameters applied, number of sessions, photosensitizer concentration, and the timing of the intervention to offer clinicians an indication of the most likely optimal techniques and parameters required to achieve clinical success. Methods: This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA Checklist and registered at the International Prospective Register of Systematic Reviews (PROSPERO). We searched and identified articles of the subsequent bibliographic databases: PubMed and Cochrane. Results: Since there are no clinical trials regarding the association of PDT and PBM in the treatment of herpes labialis, we only included case reports in our review. All studies used methylene blue solution as the photosensitizer and the laser (diode laser or low-power laser) with a wavelength of 660 nm as the light source. Power output, power density, number of irradiation points, number of PBM sessions, and irradiation duration varied between the included studies. Despite the diversity in parameters between studies, all case reports showed good results regarding relieving symptoms, accelerating healing, as well as reducing the incidence of recurrence without side effects. Conclusions: The association of PDT in the vesicular phase and PBM in the crust phase can be considered a promising solution for recurrent labial herpes. Despite the many successful cases reported, establishing an effective clinical protocol for the treatment of herpes labialis using PDT followed by PBM will only be possible through double-blind placebo studies that would elucidate the exact action of this treatment modality, the appropriate irradiation parameters for both therapies, optimal timing, and number of PBM sessions following PDT. This review has been registered at the International Prospective Register of Systematic Reviews (PROSPERO) under number CRD42021290757.

The aim of this work is to fabricate supercapacitor electrode based on poly (3-hexyl-thiophene-2, 5-diyl) (P3HT) and single-walled carbon nanotubes (SWCNTs) nanocomposites with different ratios onto a graphite sheet as a substrate with a wide voltage window in nonaqueous electrolyte. Structural, morphological and electrochemical properties of the prepared nanocomposites of P3HT/SWCNTs were studied and discussed. The electrochemical properties included cyclic voltammetry (CV), galvanostatic charging-discharging (GCD), and electrochemical impedance spectroscopy (EIS) were investigated. The obtained results indicated that P3HT/SWCNTs nanocomposite possesses higher specific capacitance than that present in its individual component. The high electrochemical performance of the nanocomposite was due to formation of microporous structure which facilitates ions diffusion and electrolyte penetration in these pores. The morphological micrographs of the purified SWCNTs had buckypaper structure while the photomicrographs of P3HT/SWCNTs showed that SWCNTs appear behind and front of the P3HT nanospheres. The specific capacitance of 50% SWCNTs at 0.5 Ag-1 was found to be 245.8 Fg-1 compared with that of pure P3HT of 160.5 Fg-1.
RESUMO
An electrochemical deposition technique was used to fabricate polypyrrole (Ppy)/NiO nanocomposite electrodes for supercapacitors. The nanocomposite electrodes were characterized and investigated by Fourier transform infrared spectroscopy (FTIR), X-ray Diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS). The performance of supercapacitor electrodes of Ppy/NiO nanocomposite was enhanced compared with pristine Ppy electrode. It was found that the Ppy/NiO electrode electrodeposited at 4 A/cm-2 demonstrated the highest specific capacitance of 679 Fg-1 at 1 Ag-1 with an energy density of 94.4 Wh kg-1 and power density of 500.74 W kg-1. Capacitance retention of 83.9% of its initial capacitance after 1000 cycles at 1 Ag-1 was obtained. The high electrochemical performance of Ppy/NiO was due to the synergistic effect of NiO and Ppy, where a rich pores network-like structure made the electrolyte ions more easily accessible for Faradic reactions. This work provided a simple approach for preparing organic-inorganic composite materials as high-performance electrode materials for electrochemical supercapacitors.
RESUMO
BACKGROUND: It is imperative to establish how students view and present themselves on social media and to assess level of awareness regarding the implications of their social media presence, e-professionalism, and accountability. The study objectives were to: 1) Determine the social media usage levels among medical and pharmacy students in the United Arab Emirates (UAE); 2) Characterize the students' views and perceptions, including their awareness of e-professionalism; and 3) Compare the responses in behavior between the two groups. METHODOLOGY: A cross-sectional study was performed on 575 undergraduate students from two study disciplines, pharmacy (n = 325) and medicine (n = 250). Minor revisions were made to previously validated assessment tools and pilot tested. The study sample included students from five different universities across the country. RESULTS: In comparison to medical students, pharmacy students were observed to use social media more for learning purposes (χ2 = 6.8, P < .05). However, medical students' opinions reflected more strongly on the context of accountability and e-professionalism (χ2 = 15.8, P < .05). A considerable proportion (89%) of students felt it was discriminatory for prospective employers to use their social media profile information for investigative purposes while hiring. One-third of respondents reported sharing information that they would not want their employers to view, and 67.1% reported the same for information relevant to patients. CONCLUSION: The research findings converge to address the need for educators and administrators in the UAE to develop guidelines concerning its safe use and proactively integrate e-professionalism into their respective curriculum.

Nanotoxicology is argued and considered one of the emerging topics. In this study, polyaniline (PANI)/2-acrylamido-2-methylpropanesulfonic acid (AMPSA) capped silver nanoparticles (NPs)/graphene oxide (GO) quantum dots (QDs) nanocomposite (PANI/Ag (AMPSA)/GO QDs NC) as a nanoadsorbent has a potential for removal of toxic hexavalent chromium (Cr(VI)) ions from water. The acute toxicity of this NC was evaluated on Artemia salina and freshwater Ostracods (Cypridopsis vidua) larvae for 48 h. The measurements were made at 24 and 48 h with 3 repetitions. The 50% effective concentration (EC50) values of the NC were determined after the exposure of these organisms. According to the results of the optical microscope, it was found that both experimental organisms intake the NC. In the toxicity results of Ostracods, the NC had a highly toxic effect only at 250 mg/L after 48 h and the EC50 value was 157.6 ± 6.4 mg/L. For Artemia salina individuals, it was noted that they were less sensitive than the Ostracods and EC50 value was 476 ± 25.1 mg/L after 48 h. These results indicated that PANI/Ag (AMPSA)/GO QDs NC has low toxicity towards both investigated organisms.
