Objectives:
This work sought to study the prevalence of non-carious cervical lesions (NCCLs) in a Burkinabe population consulting at the Municipal Oral Health Center of Ouagadougou.

Material and Methods:
This was a descriptive cross-sectional study. It was carried out between August 1, 2020, and October 31, 2020. The study population consisted of all adult patients regardless of the reason for consultation. The diagnoses of abrasion, erosion, and abfraction were based on the morphology of the clinical forms of each of these lesions as already described in the literature.

Results:
During the study period, 595 patients were examined and 82 of them had at least one NCCL, for an overall prevalence of 13.8%. Abrasion lesions were the encountered the most (47.4%), followed by abfractions (27.1%) and erosions diagnosed in 25.5% of cases.

Conclusion:
NCCLs are pathologies of the neck of the tooth that is of great concern both in terms their clinical and etiological diagnosis as well as their therapy. The prevalence reported in this study is of importance to all oral health professionals, who need to be well aware that NCCL is increasingly a major reason for seeking care.

Published: November 2022

Objective:
The purpose of this study was to comparatively evaluate two caries excavation methods-Smartprep(SS White) burs and Carisolv (Carisolv™) by measuring the Vickers hardness of prepared cavity.

Materials and Methods:
40 extracted human molars with moderate occlusal caries were used in this study. Teeth with moderate caries extending till dentin without pulp involvement were selected. RVG was used to assess the depth of the cavity. The samples were divided into 2 groups, Group I by Smart prep burs and Group II using Carisolv. Each groups were subjected to morphological analysis under scanning electron microscope.

Results:
The samples prepared with Carisolv showed least difference in hardness values between the prepared surface and surrounding dentin compared to Smartprep burs. SEM analysis with Smartprep burs revealed surface covered with debris and smear layer while Carisolv showed rough and scaly surface with large areas with open dentinal tubules.

Conclusion:
Removal of infected carious dentin was superior when Carisolv was employed as compared to SmartPrep burs. The results concluded that smear layer removal of Carisolv was superior when compared to SmartPrep burs.

Published: November 2022

Введение очередного пакета санкций в связи с началом военной операции на Украине особенно сильно меняет условия функционирования в секторах, ориентированных на внешний рынок. К таковым относится золотодобывающая отрасль, использующая высокопроизводительную зарубежную технику на добыче и реализующая продукцию на мировом рынке. Рассмотрены факторы, осложняющие работу отрасли на современном этапе и ведущие к увеличению себестоимости производства и снижению цены реализации золота: применение санкций к крупнейшим банкам-партнерам недропользователей, запрет зарубежными странами на приобретение российского золота и на ввоз импортного оборудования и запасных частей, снижение курса доллара к рублю. На примере конкретного предприятия в Магаданской области выполнена оценка эффективности добычи россыпного золота в изменившихся в условиях. Предложены меры федерального и регионального уровня, способные сгладить остроту возникших проблем в отрасли и последствий для экономики моноресурсного северного региона.
BENEFICIOS DEL DESARROLLO DE LA FUERZA Y LA RESISTENCIA EN EL MEDIO ACUÁTICO
Authors: Herrera Rodríguez Manuel Andrés , Ernesto Avella Rafael 
Published: November 2022

Existen investigaciones que demuestran que los beneficios obtenidos en el medio acuático son similares a los alcanzados en tierra, aspectos como el gasto calórico que alcanza índices 1 – 2 Kcal/min comprueban dicha relación. Los movimientos globales utilizados en el medio acuático reclutan un mayor número de grupos musculares, por lo que se favorece la capacidad aeróbica al presentar un gasto de oxígeno mayor, que por consecuencia no solo influirá en las células musculares y la capacidad de resistencia aeróbica y anaeróbica, sinotambién, influirá sobre el corazón, los pulmones y el sistema vascular. Al ser la pérdida de calor 25 veces mayor en el medio acuático con respecto al terrestre, se verá facilitada la termorregulación favoreciendo a aquellas personas que no están acostumbradas a la sudoración excesiva y el aumento de la temperatura experimentada en el entrenamiento físico. Como una actividad más agradable se puede definir al acondicionamiento en el medio acuático, porque favorece la percepción de movimientos creando la noción de un esfuerzo más liviano, que otras más intensas realizadas en el medio terrestre, otro de los grandes beneficios de este trabajo es la disminución y casi ausencia de las lesiones, este es un beneficio extra que no pueden brindar otros trabajos, al igual que las personas con problemas de sobrepeso u obesidad ven disminuido su peso en el agua, lo que permite su inclusión en los programas de entrenamiento.

IntroductionAfter the rapid surge of a novel coronavirus (SARS-CoV-2) in 2020 anti-SARS-CoV-2 vaccines have been developed to prevent the development of critical forms of COVID-19 leading to Intensive Care Unit (ICU) admission. The possibility of ICU admission after the first-cycle vaccination has been already reported; however, no data have been published regarding vaccinated patients with a “booster” dose. This retrospective study describes the characteristics of critically ill patients after the implementation of the regional “booster” dose vaccination program in a southern region of Italy.Materials and methodsWe screened all medical records of critically ill COVID-19 patients in the period between January to April 2022. We collected the demographic characteristics, the presence of comorbidities, the vaccination status, the clinical course (arterial blood gases and type of respiratory support) and outcomes (rate of tracheostomy, ICU length of stay and mortality).ResultsA total of 272 patients were admitted to ICUs during the study period. 161 patients were unvaccinated, whereas 111 were vaccinated with the complete first-cycle or “booster” dose. The type of respiratory support was similar between groups. Vaccinated patients were characterized by a better oxygenation throughout the whole ICU length of stay. Fourteen unvaccinated and 3 vaccinated patients required tracheostomy (p = 0.045). ICU length of stay was 12.2 (± 7.3) days in unvaccinated patients and 10.4 (± 6.7) days in vaccinated patients (p = 0.036). ICU mortalities were 38.5 and 24.3% in unvaccinated and vaccinated patients, respectively (p = 0.014).ConclusionVaccinated patients have better clinical course and outcomes as compared to the unvaccinated population.

Published: November 2022

Background and purposePatients with ischemic stroke frequently develop hemorrhagic transformation (HT), which could potentially worsen the prognosis. The objectives of the current study were to determine the incidence and predictors of HT, to evaluate predictor interaction, and to identify the optimal predicting models.MethodsA prospective study included 360 patients with ischemic stroke, of whom 354 successfully continued the study. Patients were subjected to thorough general and neurological examination and T2 diffusion-weighted MRI, at admission and 1 week later to determine the incidence of HT. HT predictors were selected by a filter-based minimum redundancy maximum relevance (mRMR) algorithm independent of model performance. Several machine learning algorithms including multivariable logistic regression classifier (LRC), support vector classifier (SVC), random forest classifier (RFC), gradient boosting classifier (GBC), and multilayer perceptron classifier (MLPC) were optimized for HT prediction in a randomly selected half of the sample (training set) and tested in the other half of the sample (testing set). The model predictive performance was evaluated using receiver operator characteristic (ROC) and visualized by observing case distribution relative to the models' predicted three-dimensional (3D) hypothesis spaces within the testing dataset true feature space. The interaction between predictors was investigated using generalized additive modeling (GAM).ResultsThe incidence of HT in patients with ischemic stroke was 19.8%. Infarction size, cerebral microbleeds (CMB), and the National Institute of Health stroke scale (NIHSS) were identified as the best HT predictors. RFC (AUC: 0.91, 95% CI: 0.85–0.95) and GBC (AUC: 0.91, 95% CI: 0.86–0.95) demonstrated significantly superior performance compared to LRC (AUC: 0.85, 95% CI: 0.79–0.91) and MLPC (AUC: 0.85, 95% CI: 0.78–0.92). SVC (AUC: 0.90, 95% CI: 0.85–0.94) outperformed LRC and MLPC but did not reach statistical significance. LRC and MLPC did not show significant differences. The best models' 3D hypothesis spaces demonstrated non-linear decision boundaries suggesting an interaction between predictor variables. GAM analysis demonstrated a linear and non-linear significant interaction between NIHSS and CMB and between NIHSS and infarction size, respectively.ConclusionCerebral microbleeds, NIHSS, and infarction size were identified as HT predictors. The best predicting models were RFC and GBC capable of capturing nonlinear interaction between predictors. Predictor interaction suggests a dynamic, rather than, fixed cutoff risk value for any of these predictors.

Published: November 2022

Background and aimsSichuan dark tea (ST), Zangcha, is a traditional fermented Chinese tea found in Sichuan and Tibet and claimed for beneficial effects against lifestyle-related metabolic disorders. We examined the effects of ST on lipid metabolism and atherosclerosis.Methods and resultsSichuan dark tea was given to fat-rich diet-induced atherosclerosis model rats in comparison with dark-fermented Chinese Pu-erh tea (PT) and Japanese green tea (GT). After 8 weeks of feeding, ST and PT induced an increase in high-density lipoprotein (HDL)-cholesterol and a decrease in glucose, and ST decreased triglyceride in plasma. ST also induced low pH in the cecum. There was no significant change in their body weight among the fat-feeding groups but a decrease was found in the visceral fat and liver weight in the ST group. Accordingly, ST reduced lipid deposition in the aorta in comparison with PT and GT. ST increased mRNA of LXRα, PPARα, PPARγ, and ABCA1 in the rat liver. The extract of ST stimulated the AMPK pathway to increase the expression of ABCA1 in J774 cells and increased expression of lipoprotein lipase and hormone-sensitive lipase in 3T3L1 cells, consistent with its anti-atherogenic effects in rats. High-performance liquid chromatography analysis showed unique spectra of original specific compounds of caffeine and catechins in each tea extract, but none of them was likely responsible for these effects.ConclusionSichuan dark tea increases plasma HDL and reduces plasma triglyceride to decrease atherosclerosis through AMPK activation. Further study is required to identify specific components for the effects of this tea preparation.

ObjectiveThe COVID-19 pandemic has had many negative effects on the physical and mental health of college students. Although many studies have analyzed the association between muscular fitness and psychological symptoms in children and adolescents, research during the COVID-19 pandemic is limited. Our study focused on analyzing the association between duration of muscle exercise and psychological symptoms among Chinese college students during the COVID-19 pandemic.MethodA four-stage stratified whole-group sampling method was used to investigate basic demographic information, duration of muscle exercise and psychological symptoms in 5,559 college students aged 19–22 years in China. Chi-square test (categorical variables) and one-way ANOVA (continuous variables) were used to compare the psychological symptoms of college students with different durations of muscle exercise. Logistic regression analysis was used to analyze the association between duration of muscle exercise and psychological symptoms.ResultThe detection rate of psychological symptoms among Chinese college students was 9.0%; the detection rate was 10.7% for boys and 7.6% for girls. The proportions of duration of muscle exercise at &lt;30 min/d, 30–60 min/d, and &gt;60 min/d were 75.0%, 20.4%, and 4.6%, respectively. After adjusting for relevant confounding variables, taking Chinese college students with duration of muscle exercise &gt;60 min/d as the reference group, duration of muscle exercise &lt;30 min/d was positively correlated with the occurrence of psychological symptoms (OR: 4.19, 95%CI: 1.82, 9.61) (P &lt; 0.001). In emotional symptoms (OR: 4.56, 95%CI: 1.99, 10.44), behavioral symptoms (OR: 3.44, 95%CI: 1.79, 6.60), social adaptation difficulties (OR: 3.04, 95%CI: 1.62, 5.68) dimensions, there is also a positive correlation (P &lt; 0.01).ConclusionsThe negative association between duration of muscle exercise and psychological symptoms among Chinese college students also suggests that longer duration of muscle exercise among college students is associated with a lower prevalence of psychological symptoms. The association between duration of muscle exercise and psychological symptoms was higher in boys compared to girls.

IntroductionCardiac injury has received considerable attention due to the higher risk of morbidity and mortality associated with coronavirus disease. However, in a developing country, there is a scarcity of data on cardiac injury in COVID-19 patients related to inflammatory biomarkers.MethodsTherefore, the present research retrospectively analyzes data from three territorial hospitals in Pakistan's Punjab province to investigate the potential impact of the cardiac injury on the mortality and severity of COVID-19-infected patients. We evaluated 2,051 patients between January 16 and April 18, 2022, with confirmed COVID-19. The in-hospital mortality recorded for the selected sample size was about 16.28%.ResultsThe majority of the participants were identified as male (64%) with a median age of 65 years. Also, fever, fatigue, and dyspnea were reported as common symptoms. An aggregate of 623 patients (30.38%) had a cardiac injury, and when these patients are compared to those without cardiac injury, the participants were significantly older and had more comorbidities with higher leukocyte counts, elevated levels of C-reactive protein, interleukin-6, procalcitonin, myohemoglobin, creatinine kinase-myocardial band, serum creatinine, high-sensitivity troponin-I, N-terminal pro-B-type natriuretic peptide had a significant amount of multiple ground-glass opacity and bilateral pulmonary infiltration in radiographic results. Participants with heart injury required more non-invasive or invasive mechanical respiration than those who did not have a cardiac injury. Individuals with cardiac injury had higher rates of sepsis, acute respiratory distress syndrome (ARDS), d-dimer concentration, and respiratory failure than those without cardiac injury. Patients who had had a cardiac injury died at a higher rate than those who had not suffered cardiac damage. In the multivariable logistic regression analysis, participants with cardiac injury showed greater odds of COVID-19 mortality and were found associated with older age (OR = 1.99, 95% CI = 0.04–3.19), elevated cardiac troponin I (OR = 18.64, 95% CI = 13.16–23.01), the complication of sepsis (OR = 10.39, 95% CI = 7.41–13.39) and ARDS (OR = 6.65, 95% CI = 4.04–8.91).ConclusionCardiac injury is a frequent complication among patients with coronavirus-induced infection in Punjab, Pakistan, and it is significantly linked to a greater risk of in-hospital mortality.

Published: November 2022

IntroductionMost previous studies have investigated consumer purchasing behavior for food products in urban areas during the COVID-19 pandemic. In contrast, the present study is one of the very few to investigate consumer purchasing behavior for food products within rural areas.MethodsTo this end, research was conducted in Sicily taking as a case study a rural municipality whose population was subjected to a lockdown regime to contain the spread of the virus. The choice of carrying out the research in a rural rather than an urban area contributed to the emergence of new aspects concerning consumer behavior in rural areas during the COVID-19 emergency.Results and discussionThe research reveals that the amount of money spent on food purchases, as well as the amount of food purchased, increased during the lockdown. In general, the research shows that COVID-19 impacted the purchasing behavior of consumers in rural areas even though they showed a high resilience and adaptation to the health emergency situation caused by the pandemic.

Abstract
Surface acoustic wave (SAW) resonator based on the piezo film on a foreign substrate is promising to enhance the performance of radio frequency filters. In this work, the 4 inch wafer-scale lithium tantalate thin film on quartz (LTOQ) heterogenous substrate was fabricated by ion-cut process. The cut angle of quartz was optimized to achieve high-quality factor (Q) based on finite element analysis. The average film thickness and the film nonuniformity for the whole wafer are 602 nm and ±2.2%, respectively. The lithium tantalate film exhibits single-crystalline quality where the full width at half-maximum of high-resolution X-ray diffraction rocking curve is 47.4 arcsec. The shear horizonal surface acoustic wave resonator based on the LTOQ structure exhibits a maximum Bode-Q exceeding 3000 and the electromechanical coupling coefficient of 10.26%. The temperature coefficient of frequency at resonant frequency and anti-resonant frequency are −25.21 ppm °C−1 and −35.22 ppm °C−1, respectively.
