Published: November 2024

Este artigo investiga o uso da toxina botulínica na estética facial, com ênfase nos seus efeitos na autoimagem e na saúde psicológica dos pacientes. Por meio de uma revisão de literatura, analisam-se os principais benefícios estéticos associados ao uso da toxina, como a redução de rugas faciais e a consequente melhora na autoestima. Diversos estudos indicam que o rejuvenescimento facial proporcionado pela toxina botulínica tem um impacto significativo na percepção de beleza e satisfação pessoal, favorecendo uma visão mais positiva da própria aparência. Entretanto, além dos efeitos estéticos positivos, também são discutidos os riscos relacionados ao uso frequente da toxina botulínica, como a dependência estética e a dismorfia corporal, transtorno caracterizado pela insatisfação constante com a própria imagem. Essas questões ressaltam a importância de um acompanhamento psicológico adequado, para garantir que as expectativas em relação aos resultados sejam realistas e bem gerenciadas.

Rationale of Study – COVID-19 is a novel coronavirus that has resulted in an outbreak of viral pneumonia around the world. The total case has reached 3,581,783 (shared 78.5%) with 102,201 (84.4%) total deaths and 3,214,512 (78.7%) recoveries in the top 10 infected African countries as of April 28, 2021 at 10:30 am. This study models and forecasts COVID-19 new cases in the top 10 infected African countries from February 14 to September 06, 2020. Methodology – The COVID-19 new cases data was modelled and forecasted using curve estimation regression model and time series model from February 14 to September 6, 2020. Findings – The cubic regression models for the data were relatively the best fit for Egypt, Ethiopia, Kenya, Morocco, Nigeria, and South Africa. The quadratic regression models for the data were the best fit for Cameroon, Cote dʹIvoire, and Ghana. The Algerian data was followed by the logarithmic regression model. In the time series analysis, the Algeria, Egypt, and South Africa COVID-19 new cases data have fitted the ARIMA (0,1,0), ARIMA (0,1,0), and ARIMA (0,1,14) models, respectively. The Cameroon, Côte d’Ivoire, Ghana and Nigeria data have fitted the simple exponential smoothing models. Ethiopia, Kenya, and Morocco data have followed the Damped trend, Holt, and Brown exponential smoothing models, respectively. Implications – The findings of the study may be used for preparedness planning against further spread of the COVID-19 epidemic in African countries. The author recommends that as many countries continue to relax restrictions on movement and mass gatherings, and more are opening of their air spaces and other sectors, strong and appropriate public health and social measures must be instituted to prevent further spread of the virus.

Published: November 2024

Background
The increased utilization of digital screens is an unavoidable consequence of the technology era. Digital eye strain (DES) is a prevalent health problem among higher education students in Saudi Arabia, especially health sciences students due to the frequent use of digital sources and virtual classes. Thus, this study aimed to assess the severity of digital eye strain syndrome (DESS) symptoms and preventive ergonomic practices among higher education health science students in Saudi Arabia.

Methods
A cross-sectional study using multistage cluster sampling in three cities (Dammam, Riyadh, Jeddah) in Saudi Arabia. A convenient sample of 328 health science students was selected using an equal allocation technique. The researchers designed and used an online survey of three sections: personal and digital device use-related data, the DESS questionnaire, and the self-reported preventive ergonomic practices scale.

Results
DESS is a widespread problem among 72.0% of health science students, and 58.2% had unsatisfactory ergonomics. The frequently reported symptoms were blurred vision (32.9%) and increased sensitivity to light (33.5%). The severe eye-related symptoms were headache (45.85%), foreign body inside the eye (43.71%), eye burning (40.19%), and dryness (39.76%). Logistic regression analysis revealed that the female sex, years of screen utilization and the number of hours per day, screen use without rest, and frequency of virtual classes per week, eye disease, digital screen utilization for studying, nonuse of protective eye measures, and using numerous digital devices were significant predictors of DESS risk (P < 0.05).

Conclusions
DESS is a common problem among many health science students, with headaches and foreign body sensations in the eye being the most frequent symptoms. Screen utilization time and eye disease are significant predictors of DESS, while most items’ application of ergonomic practices was low. Educational programs are needed to increase student’s awareness of ergonomic practices.

Published: November 2024

Background: Several factors on melasma etiopathogenesis have been suggested, yet the exact pathophysiology of melasma is uncertain. However, controversial results exist now on Zn and Cu in serum of melasma patients.
Objectives: This study was done to measure the serum level of Zinc and Copper and to evaluate their influence on the duration and severity of melasma.
Patients and Methods: A Case- control study involved a total of 200 patients (melasma group 100 and equal number of healthy controls), The two groups were matched for age and sex. A sample of blood was taken from both cases and controls for assessment of serum zinc and serum copper, sent to the same lab and read by the same method for both groups, and then to compare the relation of these values with demographic data.
Results: the serum zinc level was low in 51% of the patients with melasma, 47% had normal serum zinc level and only 2% had high serum zinc level. While only 5% had low serum copper level, 66% had normal serum copper level, and 29% had high serum copper levels. Analysis of means of serum zinc and serum copper levels revealed significant difference in means of serum zinc between cases and controls (p<0.001), and low serum zinc was highly associated with melasma cases (p<0.001). Furthermore, there was a significant association between duration of melasma and serum zinc level; duration ≤ 2 years was associated significantly with normal serum zinc level (P=0.03). However, there was no significant difference in means of serum copper between cases and controls (P=0.5).
Conclusion: The results of the present study showed that there is a significant relation between serum zinc levels and melasma while showed no significant relation between serum copper and melasma. Low serum zinc level may be one of the risk factors that effects the melasma duration.
Prevalence and Determinants of Complementary and Alternative Medicine Use among Children living with Epilepsy in Port Harcourt, Nigeria
Authors: Wobo Kininyiruchi N. , Gabriel-Job Nneka 
Published: November 2024

Introduction: Epilepsy is a common neurologic disorder in children with its management centered on the use of anti-seizure medications (ASM). However, many children do not achieve seizure control despite being on the appropriate ASM. Hence, caregivers may seek complementary and alternative medicines (CAMs) therapies. The aim of this study is to investigate the prevalence and types of CAM used by children with epilepsy in a tertiary hospital in Port Harcourt, Nigeria, and the factors that determines their use.
Methods: A descriptive cross-sectional study was conducted among children diagnosed with epilepsy and their caregivers. Participants were recruited using a convenient sampling method, a structured questionnaire was used to collect data. Descriptive statistic was performed using IBM SPSS while Pearson’s chi-square test was used to identify significant associations.
Results: The prevalence of CAM use was found to be 84.3%, the use of CAM is a risk for poor adherence to ASM. Family members were the main influencers in the decision to use CAM, and the majority of parents/caregivers did not consult their children’s healthcare providers before incorporating these therapies. Significant factors influencing the use of CAM includes: being a male (P=0.01), higher seizure frequency (P=0.002), multiple ASM use (P=0.01), and the presence of comorbidities (P=0.04). The most common CAMs used were prayers, kernel or crude oil and scarifications.
Conclusion: CAM use among children with epilepsy is common and is a cause of poor adherence to ASMs with its untoward effects. It is crucial for healthcare providers to proactively inquire about the use of CAM with caregivers during the management of childhood epilepsy and to educate them on the possible risks specifically regarding drug adherence, compliance and poor seizure control.

Published: November 2024

Soil and Water Assessment Tool (SWAT), a popular hydrological model, created to impersonate how the land management techniques would affect the water availability, sediments transportation and nutrient transformations in region’s expansive and intricate watersheds. SWAT has evolved from its initial development state as a comprehensive modelling tool for agricultural systems, watershed management and climate change adaptation. SWAT predicts the effects of agricultural practices on water, sediment and nutrient loads. Moreover, over time, its functionality has broadened to include complex environmental processes, such as sediment transport, nutrient cycling, and land-use change dynamics. This review paper mainly focused on the literature collected on its relevance and applicability to agricultural sector and climate change. Moreover, the incorporation of SWAT into studies on climate change has broadened its scope by enabling it to simulate the possible consequences of fluctuating temperature patterns, unpredictable precipitation, and severe weather on worldwide water resources and farming systems. In addition to highlighting its practical applicability, case studies from India and other locations also highlighted in current review article. For policymakers, agricultural scientists, SWAT is an essential tool because of its capacity to model the long-term effects of land and water management at broad spatial and temporal dimensions. SWAT also found to help the stakeholders for creating plans to lessen the effects of climate variability by combining several climate models and scenarios and to provide better insights on future soil erosion, flood hazards and water availability. Overall, in light of the escalating environmental issues, SWAT is essential for sustainable management of water and agricultural resources due to its capacity to produce comprehensive and long-term projections.

AbstractA new approach is presented, based on the unexpectedly versatile role of transition metal ions, to produce high‐quality graphene via an anodic electrochemical exfoliation route, and the capability of the resultant material in energy storage applications are illustrated. The method is based on graphene exfoliation in the presence of transition metals (Co2+ and Fe3+) which act as antioxidants, preventing surface oxidation of graphene, while other metals (Ru3+, Mn2+, Ir3+, and Sn4+) act as metal oxide decorators. The addition of Co2+ ions to the exfoliation solution produced few‐layer graphene that is two orders of magnitude more conducting and contains 80% less oxygen than the material obtained in the absence of cobalt ion. By contrast, the use of Mn2+ and Ru3+ in the electrolyte form an interconnected honeycomb lamellar structure of MnO2 and RuO2 nanoparticles, respectively. The combination of Mn2+ and Ru3+ create a uniformly grown Ru–Mn oxide hybrid structure on the graphene sheets in a single stage process, which is found to be an efficient electrode for supercapacitors (specific capacitance of 500 F g−1) and as a bifunctional water splitting electrocatalyst. The use of these inexpensive salts will aid the scalable production of high‐quality graphene and functionalized graphene for diverse applications.

AbstractPhotovoltaic technologies based on perovskite absorber materials have led this optoelectronic field into a brand‐new horizon. However, the present antisolvents used in the one‐step spin‐coating method always encounter problems with the very narrow process window. Herein, anisole is introduced into the one‐step spin‐coating method, and the technology is developed to fabricate perovskite thin films with ultrawide processing window with a dimethylformamide (DMF):dimethyl sulfoxide (DMSO) ratio varying from 6:4 to 9:1 in the precursor solution, anisole dripping time ranging from 5 to 25 s, and an antisolvent volume varying from 0.1 to 0.9 mL. Perovskite thin films as large as 100 cm2 are successfully fabricated using this method. Maximum photoelectric conversion efficiencies of 19.76% for small‐area (0.14 cm2) and 17.39% for large‐area (1.08 cm2) perovskite solar cell devices are obtained. It is also found that there are intermolecular hydrogen‐bonding forces between anisole and DMF/DMSO that play critical roles in the wide process window. These results provide a deeper understanding of the crystallizing procedure of perovskite during the one‐step spin‐coating process.

Published: October 2018

AbstractPhotonic memories as an emerging optoelectronic technology have attracted tremendous attention in the past few years due to their great potential to overcome the von Neumann bottleneck and to improve the performance of serial computers. Nowadays, the decryption technology for visible light is mature in photonic memories. Nevertheless, near‐infrared (NIR) photonic memristors are less progressed. Herein, an NIR photonic memristor based on MoS2–NaYF4:Yb3+, Er3+ upconversion nanoparticles (UCNPs) nanocomposites is designed. Under excitation by 980 nm NIR light, the UCNPs show emissions well overlapping with the absorption band of the MoS2 nanosheets. The heterostructure between the MoS2 and the UCNPs acting as excitons generation/separation centers remarkably improves the NIR‐light‐controlled memristor performance. Furthermore, in situ conductive atomic force microscopy is employed to elucidate the photo‐modulated memristor mechanism. This work provides novel opportunities for NIR photonic memory that holds promise in future multifunctional robotics and electronic eyes.

Published: October 2018

AbstractThe intuitive use, inexpensive fabrication, and easy readout of colorimetric sensors, including photonic crystal architectures and Fabry–Pérot interference sensors, have made these devices a successful commercial case, and yet, understanding how the diffusion of analytes occurs throughout the structure is a key ingredient for designing the response of these platforms on demand. Herein, the diffusion of amines in a periodic multilayer system composed of two‐dimensional nanosheets and dielectric nanoparticles is tracked by a combination of spectroscopic measurements and theoretical modelling. It is demonstrated that diffusion is controlled by the molecular size, with larger molecules showing larger layer swelling and slower diffusion times, which translates into important sensor characteristics such as signal change and saturation time. Since the approach visualizes the analyte impregnation process in a time‐ and spatially resolved fashion, it directly relates the macroscopic color readout into microscopic processes occurring at the molecular level, thus opening the door to rational sensor design.

AbstractSpectral stability and high color rendering index (CRI) remain challenges to high‐performance, solution‐processed white organic light‐emitting devices (WOLEDs) based on two complementary colors. The solution‐processed WOLED based on two thermally activated delayed fluorescence emitters with complementary color, i.e., the orange–red 2‐[4‐(diphenylamino) phenyl]‐10,10‐dioxide‐9H‐thioxanthen‐9‐one emitter and the blue 4,4′‐bis(carbazol‐9‐yl)‐2,2′‐dimethylbiphenyl:4,6‐bis(3,5‐di(pyridin‐4‐yl)phenyl)‐2‐phenylpyrimidine interface exciplex, is reported here. Poly[(9,9‐dioctylfluorenyl‐2,7‐diyl)‐co‐(4,4′‐(N‐(4‐sec‐butylphenyl)) diphenylamine)] is doped with 30 wt% cross‐linkable N,N′‐(4,4′‐(cyclohexane‐1,1‐diyl)bis(4,1‐phenylene))bis(N‐(4‐(6‐(2‐ethyloxetan‐2‐yloxy)hexyl)phenyl)‐3,4,5‐trifluoroaniline) to form a smooth hole transportation layer with outstanding solvent resistance ability and efficient hole transporting/injection ability. The position of interface exciplex and exciton management in the emitting layer can be tuned, thus anchoring the color stability. The device displays a maximum external quantum efficiency of 10.02% and a high CRI of 85 with Commission Internationale de l'Eclairage (CIE) color coordinates of (0.32, 0.33) at the luminescence of 1000 cd m−2. These results are among the best of solution‐processed WOLEDs based on two complementary chromophores.

AbstractNanopatch antennas based on the assembly of nanocubes are an appealing way to easily produce structures that feature very thin gaps between metals at a very low cost compared with other surface modification techniques. If these coatings are very good absorbers in the visible and near‐infrared range, they can also be of interest for reaching light confinement regimes where nonlocality arises strongly, or for designing molecular electronics junctions embedded in resonating cavities. Here both modeling and experimental realization of a nanocube assembly approach based on alkyldithiols molecules is proposed that enables a high reproducibility on the resonance position of the cavities, as well as gaps that are thinner than the usual 3 nm limit often reported in the literature, thus opening the way to experimental confirmation of nonlocal effects as well as new perspectives for molecular electronics.

Published: October 2018

AbstractFor decades, ultrafast time‐resolved spectroscopy has found its way into an increasing number of applications. It has become a vital technique to investigate energy conversion processes and charge transfer dynamics in optoelectronic systems such as solar cells and solar‐driven photocatalytic applications. The understanding of charge transfer and photochemical reactions can help optimize and improve the performance of relevant devices with solar energy conversion processes. Here, the fundamental principles of photochemical and photophysical processes in photoinduced reactions, in which the fundamental charge carrier dynamic processes include interfacial electron transfer, singlet excitons, triplet excitons, excitons fission, and recombination, are reviewed. Transient absorption (TA) spectroscopy techniques provide a good understanding of the energy/electron transfer processes. These processes, including excited state generation and interfacial energy/electron transfer, are dominate constituents of solar energy conversion applications, for example, dye‐sensitized solar cells and photocatalysis. An outlook for intrinsic electron/energy transfer dynamics via TA spectroscopic characterization is provided, establishing a foundation for the rational design of solar energy conversion devices.

Published: October 2018

AbstractA new concept for the meta‐selective borylation of aromatic amides is described. It has been demonstrated that while esters gave para borylations, amides lead to meta borylations. For achieving high meta selectivity, an L‐shaped bifunctional ligand has been employed and engages in an O⋅⋅⋅K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction provides exceptional control for meta C−H activation/borylation.
