Published: June 2022

Background
Postoperative care is influenced by various factors such as compliance, comprehension, retention of instructions, and other unaccounted elements. It is imperative that patients adhere to the instructions and prescribed regimen for smooth and placid healing. ExoDont, an Android-based mobile health app, was designed to ensure a smooth postoperative period for patients after a dental extraction. Besides providing postoperative instructions at defined intervals, the app also sends drug reminders as an added advantage over other available, conventional methods.

Objective
The aim of this study was to compare the compliance rate of individuals with respect to the prescribed regimen and postoperative instructions. Additionally, we aimed to assess any changes in the postoperative complication rate of patients assigned to 3 categories: the verbal, verbal plus written, and ExoDont app-based delivery groups.

Methods
We conducted a pilot, nonrandomized, and prospective comparative study in which patients after tooth extraction were assigned to 3 groups—verbal (Group A), verbal plus written (Group B), and ExoDont app-based delivery (Group C)—based on the eligibility criteria, and a 1-week follow-up was planned to obtain the responses regarding compliance and postoperative complications from the participants.

Results
In total, 90 patients were recruited and equally divided into 3 groups. Compliance to prescribed drug was found to be the highest in Group C, where of the 30 participants, 25 (83%) and 28 (93%) followed the entire course of antibiotics and analgesics, respectively. For postoperative instructions, higher compliance was observed in Group C in relation to compliance to diet restrictions (P=.001), not rinsing for 24 hours (P<.001), and warm saline rinses after 24 hours (P=.001). However, the difference was not significant for smoking restrictions (P=.07) and avoiding alcohol (P=.16). Moreover, the difference in postoperative complication rate was not statistically significant among the 3 groups (P=.31).

Conclusions
As evident from the results, it is anticipated that the ExoDont app will be helpful in circumventing the unaccounted possibilities of missing the prescribed dosage and postoperative instructions and ensuring the smooth recovery of patients after dental extraction. However, future studies are required to establish this app-based method of delivery of postoperative instructions as a viable option in routine clinical practice.

Published: June 2022

Mesoporous silica (MS) supported by nickel was synthesized from Parangtritis beach sand and assessed for its activity and selectivity as catalysts in hydrocracking waste cooking oil into biofuel. The synthesis of MS was done by the sol-gel method. Ni/MS catalysts using Ni weight variations of 1, 5, and 10 wt.% were denoted as Ni/MS1, Ni/MS5, and Ni/MS10 and were compared to standard mesoporous silica (Ni/SBA-15). The catalysts were characterized using FTIR, XRD analysis, N2 gas sorption analysis, SEM-EDX, and TEM. Catalyst Ni/MS1, Ni/MS5, Ni/MS10, and Ni/SBA-15 have specific surface areas of 130.5, 195.9, 203.9, and 381.2 m2/g and the average pores of 12.30, 9.80, 11.12, and 8.70 nm, respectively. The hydrocracking was run four times to evaluate the catalyst reusability. The hydrocracking WCO has 95.8, 82.4, and 85.2%, respectively. While Liquid fractions produced were 38.8, 43.2, and 50.2 wt.%, each of which contains gasoline of 37.09, 39.76, and 44.27 wt.%, Ni/MS10 has the highest liquid products of 50.2 wt.% and was selective to gasoline fractions up to 44.27%. Therefore, the catalyst synthesized from Parangtritis beach sand is selective for gasoline-fraction hydrocarbon and has hydrocracking activity up to 4 runnings.

Los Centros de Desarrollo Infantil se caracterizan por la atención multidisciplinaria a la población infantil, sector particularmente susceptible a enfermar de las vías respiratorias por la presencia de microorganismos fúngicos que se dispersan por las corrientes de aire entre los espacios donde se encuentran los usuarios. Por lo anterior, el objetivo de este trabajo fue evaluar la concentración fúngica del aire interior del Centro de Desarrollo Infantil de la Universidad de Sonora, la identificación taxonómica de los microhongos recolectados y la descripción de su posible patogenicidad para la salud humana. Se obtuvieron entre los días del 2 al 27 de mayo 89 muestras de 17 sitios donde concurren los menores de edad y un punto testigo. Se realizaron muestreos estáticos a un metro de altura, utilizando un equipo SAS SUPER 100 y la sedimentación en placa de Petri con medio de cultivo Agar Sabouraud. Por la técnica de impronta se identificaron 14 géneros fúngicos, entre los predominantes están Cladosporium spp., Aspergillus spp. y Penicillium spp., con presencia de 31%, 26% y 16%, respectivamente. La concentración fúngica más alta que se detectó fue de 53 UFC/m3, valor inferior al considerado peligroso por diversas instituciones gubernamentales alrededor del mundo. No obstante, se identificaron especies de interés clínico del género Aspergillus, predominando en todos los sitios A. niger, seguido por A. ochraceus, A. flavus, A. versicolor y A. fumigatus.

Published: June 2022

Introducción: La anquilosis de la articulación temporomandibular (ATM) se define como la condición patológica donde la mandíbula se fusiona a la cavidad glenoidea por tejidos óseos y/o fibróticos, limitando la apertura bucal, dificultando la masticación y el habla. Objetivo: Mejorar la función mandibular disminuyendo el dolor y previniendo la reanquilosis de los casos presentados, así como proporcionar información acerca del manejo de la anquilosis de la ATM. Presentación de los casos: Se presentan dos casos clí- nicos con anquilosis de la ATM, con limitación de la apertura (13 y 10 mm), dolor intenso de tipo punzante en la zona preauricular. En ambos casos realizaron estudios de extensión (radiografías, tomografías, estereolitografía) para la planeación de los tiempos quirúrgicos. Se llevó a cabo un remplazo completo de la ATM me- diante un acetábulo y prótesis condílea de stock (Biomet Micro- fixation), la técnica quirúrgica consistió en abordaje perauricular con extensión anterosuperior y posterior abordaje submandibular, se verificaron los movimientos mandibulares de forma inmedia- ta y se indicaron ejercicios de fisioterapia durante seis meses. Resultados: En el primer caso se logró una apertura de 35 mm con movimientos mandibulares protrusivos y laterales y oclusión estable a cinco años de seguimiento. En el segundo caso se logró una apertura de 30 mm con movimientos mandibulares conser- vados. En ambos casos las pacientes refirieron satisfacción y se- guridad a la masticación de alimentos y de manera asintomática.Conclusiones: Para lograr un tratamiento eficaz, satisfactorio y duradero, es necesario un enfoque individualizado en caso, eli- giendo como primera opción el que posea una menor morbilidad para el paciente.

Introducción: El equilibrio neuromuscular consiste en la coordi- nación muscular dinámica entre la relación y la actividad de los músculos masticatorios. La férula oclusal tiene como objetivo principal producir una posición mandibular estable y reproducible. Objetivo: Analizar posibles variaciones en el equilibrio neuromus- cular con base en los registros electromiográficos de los múscu- los maseteros previos y posteriores al uso de férula oclusal en pacientes con malposiciones dentarias. Material y métodos: Se siguió una cohorte de 52 pacientes provenientes de dos clínicas odontológicas durante el periodo de agosto a diciembre de 2018, mediante un muestreo a conveniencia se realizó el examen clínico general, regional y local. Se realizó el análisis cefalométrico de las radiografías laterales de cráneo y la evaluación de la electromio- grafía mediante programas específicos, además de la elaboración y colocación de férulas oclusales fisiológicas. Se realizó un análisis bivariado [χ2 y regresión lineal, rangos de Wilcoxon (STATA)]. Resultados: La media de edad fue 22 años, 75% correspondió al género femenino y al tipo de maloclusión esquelética clase II (48%). El uso de férula provocó una disminución en las diferen- cias RMS de 27 (59%) y un aumento en 19 (41%) pacientes. La significancia asintótica del análisis determinó una diferencia signi- ficativa en la variación de la diferencia de RMS y en el índice de asimetría muscular previa y posterior al uso de férula. Con base en el estadístico de contraste (p < 0.05) no existe evidencia sufi- ciente para este conjunto de datos respecto a que las diferencias de RMS y del índice de asimetría muscular dependen del uso de férula. Conclusiones: Cualquier tratamiento dental es complejo debido a que altera la función del sistema estomatognático y estos cambios influyen en la actividad muscular, mismos que deberían considerarse correctos posterior a ser evaluados mediante patrones fisiológicos de actividad muscular.

Published: June 2022

Introducción: La pulpa dental humana es considerada una fuente celular, de la que se puede obtener fibroblastos, odontoblastos y cé- lulas troncales. Actualmente, cultivos de estas células son usados en estudios de biocompatibilidad de materiales dentales, así como en medicina regenerativa e ingeniería tisular. El tiempo postexodon- cia conforma un factor importante para la obtención de un elevado porcentaje de viabilidad celular. Reportes sobre la viabilidad celular de cultivos de células troncales de la pulpa dental no incluyen la po- blación celular total de la pulpa. Por este motivo, el objetivo de este estudio fue conocer la influencia del tiempo postexodoncia, la edad y el sexo del paciente en la obtención de células viables de pulpas den- tales. Material y métodos: Se compararon dos tiempos, antes de las 24 horas y después de las 72 horas postexodoncia. Se recolectaron un total de 42 dientes de pacientes entre 13 y 42 años de edad. Para determinar la viabilidad celular se usó la tinción de azul de tripano y se hizo el recuento celular en el microscopio. Las células vivas fueronobservadas de color blanco y las muertas de color azul. Resultados: Las pulpas que fueron obtenidas antes de las 24 horas postexodoncia presentaron un mayor porcentaje de viabilidad celular con respecto a las pulpas obtenidas después de las 72 horas postexodoncia. Con- clusiones: La obtención de las células de la pulpa dental debe reali- zarse en un tiempo ≤ a 24 horas postexodoncia para óptimos resulta- dos. Existe una relación entre la edad del paciente y la viabilidad en las pulpas obtenidas antes de las 24 horas postexodoncia. El sexo del paciente no influye en la viabilidad celular de los tiempos estudiados.

Hyperglycemia is indeed a dyslipidemia across a Globe. An International Diabetes Federation (IDF) has Predicted a certain 366 million more people have diabetes in 2011 and it has been raised up to 552 million by 2050. It approximated a certain 40 million people of hyperglycemia through India in 2007 and yet this may predicted to grow almost to 70 million affected by 2025. LD50 study of the ethanolic extract of S. emarginatus seed kernel (EESESK) has been done throughout Albino rats up to a daily dosage constrain of 2000 mg/kg orally (according to OECD guidelines No.425 of CPCSEA) 1/5th, 1/10th dosage as from maximum dose examined for LD50 study results were again for experimental test research to examine a impact of S. emarginatus for a anti diabetes action. Insulin inefficiency was found in two selected model for my study. Alloxan hydrate at such a mg dosage of 150 mg/kg i.p after 48 hrs, the EESESK seed kernel it at a dosage of 200 mg/kg but also 400 mg/kg p.o have been administered. Dexamethasone 10 mg/kg, i.p, once daily. And at the inter of 30 mins EESESK 200 mg/kg and 400 mg/kg p.o had been conducted in rats for a period of 11 and 21 days respectively. At the end of the experimental, serum biomarkers such as glycogen, high cholesterol, triglycerides, LDL, HDL, and VLDL were analyzed by using semi-auto analyzer. In both models EESESK at a dose of 400 mg/kg exhibited substantial impact. Alloxan hydrate increased serum biochemical markers like glucose, high cholesterol, triglyceides, LDL, VLDL levels but decreased HDL levels. Dexamethasone caused an increase in serum glucose, High cholesterol and reduces High density lipopretein-cholesterol levels. The present study indicates that S.emarginatus seed kernel useful for the management of diabetes mellitus. S.emarginatus pollen seed found important reducing of glycogen TC, TG, LDL, VLDL levels and increased level of High Density Lipoprotein through diabetic concept mice. A enhanced high density lipoprotein is also Cardioprotective activity. Therefore S.emarginatus seed kernel must have future role to forestall forming of atherosclerosis but also cardiovascular disease.

Published: June 2022

The present study was aimed towards the development of controlled release formulations of Losartan Potassium based on designed to enhance the bioavailability by prolonging its duration in the stomach via the floating dosage forms with controlled release. This study was intended to evaluate the influence of formulation variables like levels of polymer, amount of mannitol concentrations, and coating solution ratios of semi permeable membrane on the drug release from the developed formulations. Thus, there is a strong clinical need and market potential for a dosage form that will deliver Losartan Potassium in a controlled manner to a patient needing this therapy, thereby resulting in a better patient compliance. This study was designed to enhance the bioavailability of drug by prolonging its duration in the stomach via the floating dosage forms with controlled release. Floating matrix tablets of Losartan Potassium were prepared by the direct compression method, using locust bean gum and HPMC K 15M as polymers and Sodium bicarbonate as floating agent. The effect of the nature of polymers was studied by preparing various formulations of tablets. In all these formulations, a constant amount of drug (100 mg) was maintained. The blend was initially characterized for pre-compression and post- compression parameters. Pre-compression characterization was done for angle of repose, bulk density, tapped density, Carr’s index, and Hausner’s ratio. The results of pre-compression characterization were indicated good to excellent flow characteristics. Post-compression characterization includes thickness, hardness, friability, weight variation, drug content, buoyancy lag time, floating time and in-vitro drug release. All the results were satisfactory as per the guideline of pharmacopoeia. The in vitro drug release studies found that formulations LPFT4 showed best sustained release profile in 24 hrs. Among the nine formulations (LPFT1 to LPFT9) prepared formulations LPFT4 was found to be the best formulations in terms of sustained drug release. Drug release kinetics was performed by using various kinetic models such as Zero order, First order, Korsmeyer- Peppas and Higuchi’s equation and followed supercase II transport diffusion kinetic models.

Published: June 2022

Our objective is to assess motivation and self-regulated learning domains among undergraduate health professional students during compulsory E-learning in the COVID-19 pandemic, and explore inter-gender variabilities and the correlation between test anxiety and self-regulated learning. Institutional based descriptive study, Motivated Strategies for Learning Questionnaire (MSLQ) was administered to 291 healthy undergraduate students of health professions programs at Al Marefa University. Two months after shifting to compulsory E-learning, students were invited to return an online standardized self- administered questionnaire via Google form. Data were analyzed using SPSS version 23. Reliability analysis with an average close to or exceeds the recommended value (α = 0.7). The extrinsic motivation was higher than the intrinsic one, the use of learning strategies was modest. Female students displayed significantly higher motivation and learning strategies scores (P=0.001). Male had higher extrinsic goal orientation P= 0.001, self-efficacy P= 0.043, Help-seeking P= 0.017, while females had a higher time study environment P=0.027. Also, the youngest and oldest students were the most motivated ones (P= 0.04). A positive correlation exists between test anxiety and extrinsic goal orientation (P=0.000). Statistically significant correlations exist between test anxiety and all of the learning strategies scales. There are adequate levels of motivation with moderate use of learning strategies among health professional students during sudden shifting to compulsory E-learning in the COVID-19 pandemic. Females’ students were more self-regulated learners than males. Further investigation of the use of the Motivated Strategies for Learning Questionnaire and its association with academic achievement is recommended to assess the online teaching experience.
