IntroductionMedical simulation has become an integral part of medical student education. There is a limited body of literature comparing virtual and high-fidelity simulation in terms of effectiveness and student perception.MethodsA total of 130 medical students at the University of Rzeszów participated in this cross-sectional study. The respondents were divided into two groups: students who completed a selected scenario using a virtual patient (Body Interact) and students who completed a scenario using traditional high-fidelity (manikin-based) simulation (HFS). After completing the scenario, students filled in the following questionnaires: the Simulation Design Scale (SDS), the Educational Practices Questionnaire (EPQ), the Student Satisfaction and Self-Confidence in Learning Scale (SSCL) and a customized survey questionnaire.ResultsThe study found no significant difference in the effectiveness of HFS between students exposed to either type of simulation. Detailed analysis within specific categories – problem-solving, teamwork, and active learning – also showed no significant differences between virtual and traditional HFS. Furthermore, there were no notable differences between virtual and traditional simulations regarding specific aspects such as satisfaction with learning, self-confidence in learning, and expectations. However, within the virtual simulation group, females rated active learning significantly higher. Students aged 24–33 rated satisfaction with learning, self-confidence, overall effectiveness and perception of HFS, problem-solving, and active learning more favorably. Additionally, the levels of perceived effectiveness and satisfaction of higher years students with HFS increased.ConclusionVirtual patient simulation and traditional HFS foster the development of practical skills, as well as soft skills of medical students in challenging situations.

AimTo investigate the effect of periodontal therapy on endothelial function of subjects with periodontitis in stages III or IV and established cardiovascular disease.Materials and methodsA triple-blinded, parallel groups, randomized clinical trial of 6 months duration, on patients with history of coronary heart disease and periodontitis in stages III or IV was performed. Intervention consisted of steps 1 (oral hygiene instructions and professional mechanical plaque removal) and 2 (subgingival instrumentation) of periodontal therapy, including an antiseptic mouth rinse for 7 days. Patients in the control group received only step 1, with the adjunctive use of a fluoride-containing mouth rinse. Endothelial function (flow-mediated dilation [FMD]) and carotid intima-media thickness (cIMT) at baseline, 3 and 6 months, and serum markers of inflammation and cell adhesion at 3 days, 10 days, 3 and 6 months after therapy, were evaluated. Demographic characteristics, cardiovascular risk factors, history of cardiovascular diseases, medication intake, lipids profile, blood pressure, and periodontal outcomes were also evaluated. Student T, Mann–Whitney U, Chi-square and Fisher-exact tests were performed along with repeated measures ANOVA with post hoc Bonferroni's corrections.ResultsThirty-five patients were included. In the test group, improvements in pocket depth, bleeding on probing and suppuration at 6 months were significantly better than in control patients. Reductions in mean FMD [test group −3.43%; 95% confidence interval—CI [−2.68; 9.54], p = 0.487; control group −6.75%; 95% CI [1.29; 12.22], p = 0.012] and cIMT (test group −0.05 mm; 95% CI [0.01; 0.10], p = 0.014; control group −0.01 mm; 95% CI [−0.03; 0.05], p = 1.000) were observed in both groups from baseline to 6 months, without significant intergroup differences at any time-point. Differences between groups in serum inflammatory markers were detected at baseline and 3 days for interleukin (IL)-18, and at 10 days for IL-8.ConclusionPreliminary results from the present pilot study showed that steps 1 and 2 of periodontal treatment in subjects with periodontitis in stages III–IV and established cardiovascular disease induced improvements in cIMT and periodontal outcomes, although changes in FMD were not observed.

BackgroundUnderstanding population dynamics is essential since the number of children ever born (CEB) affects the growth, composition, and structure of a nation's population. The number of CEB has increased significantly, contributing to the world's rapid population growth. The spatial distribution of CEB in Ethiopia lacks recent information. Therefore, this study aimed to assess spatial distribution, and associated factors of CEB among reproductive age women in Ethiopia.MethodMini Ethiopian Demographic and Health Survey (MEDHS) 2019 data were used in this study. The study comprised 5527 (weighted) women's between the ages of 15 and 49. STATA and Aeronautical Reconnaissance Coverage Geographic Information System (ArcGIS) 10.8 software was used. The primary outcome, CEB, was categorized as “low” if fewer than five children were born and “high” if five or more children were born. Global and local Moran's Index methods were used to assess the extent of clustering. Multi-level (two-level) logistic regression analysis was used and variables with a P value less than 0.05 were considered statistical significance. Adjusted odds ratio AOR) with a 95% confidence interval (CI) was used to show the strength and direction of the association respectively.ResultsHigh number of CEB in Ethiopia was 37.46%, 95% CI (0.39–0.56) and it was spatially clustered (Moran's index = 0.59 P value &lt;0.0001). Significant hotspots of high CEB were found in the Eastern Somali, Hadiya, Sidama, and Welayta zones. From individual-Level variables: women who were married [AOR = 3.23, 95% CI (1.48, 6.62)] were positively associated with high number of CEB. Whereas, women who were primary educated [AOR = 0.18, 95% CI (0.12, 0.27)], women who were secondary educated [AOR = 0.0.05, 95% CI (0.02, 0.13)], women's whose age at first birth after 20 year [AOR = 0.38, 95% CI (0.27, 0.51)] and women's who were using contraceptive [AOR = 0.59, 95% CI (0.44–0.78) were negatively associated with high number of CEB. From community level variables: a community with high proportion of contraceptive non user [AOR = 1.38, 95% CI (1.94–2.04)] were positively associated with high number of CEB.ConclusionBoth individual and community-level factors were significantly linked to a high number of children born. The government is advised to prioritize interventions that promote women's education, delay first births, and provide access to a range of contraceptive options, ensuring informed, voluntary choices. Empowering women to exercise reproductive autonomy, free from coercion, is key to influencing fertility outcomes effectively.

Land and real estate, being highvalue assets, it is crucial to have authentic documents to identify and prove who is indeed the owner. However, the existing land registration processes and the use of paper certification in Vietnam and most other countries involve many vulnerabilities, leading to many land dispute cases and illegal manipulation of public land. Also, the current titling and transferring ownership procedure is quite laborious since it involves manually storing and safekeeping a large volume of registers in written form. To address this problem, alternative solutions have been proposed, including digitalizing records and storing data in a centralized database. Nonetheless, with such approaches, data transparency and its availability may not be guaranteed since data tamperingand unauthorized fraudulent change could occur in poorly maintained databases, or the system could be suspended for unexpected reasons if the servers are not appropriately backed up. In this study, a system that accelerated the land titling process and met all the required characteristics in terms of transparency and availability of data was developed. The proposed system was implemented on Ethereum blockchain, which kept all of the transactions during the land assets ownership transfer on a distributed network, therebydecreasing the cases of fraud in the process. The study then analyzed and presented several limitations of the current implementation and finally provided some possible suggestions for future improvement.

Aim. The work aims to analyze the social and economic efficiency of investments as a key source of economic growth.Objectives. The work seeks to study the importance of investments in the modern economy, identify the main factors influencing investment activity in Russia, and perform a comparative analysis of the investment climate of the regions and analyze its relationship with social and economic development.Methods. The study employed retrospective and comparative analysis, as well as statistical data. Particular attention was paid to qualitative and quantitative approaches to assessing the investment climate based on the National Investment Rating and data on the social and economic situation of the regions from the infographics of the rating agency “RIA Rating.”Results. The study revealed that investments are of key significance in the social and economic development of the regions of Russia. The leaders in terms of investment activity are Moscow, the Republic of Tatarstan and the Nizhny Novgorod Region, which have demonstrated high adaptability to economic challenges. The least favorable indicators are registered in the Republic of Kalmykia, the Karachay-Cherkess Republic, and the Republic of Tuva. In these regions, economic conditions restrict the investment raising. A close relationship between the investment attractiveness of the region and the level of socio-economic development was revealed.Conclusions. Determining the effect of investments within a region is a complex task due to their long-term nature. The time factor can significantly affect the perception and achievement of the desired result, which complicates the correlation of the socio-economic effect with the initial investment. Despite these difficulties, investments remain a key means for the long-term and sustainable economic development of Russia. A necessary condition for increasing their efficiency is the improvement of state policy in the field of stimulating investment activity, increasing the level of financial awareness of the population, developing infrastructure, and creating a favorable environment for business operations. Particular attention should be paid to regions with low investment potential, since their support is important for ensuring the balanced development of the country as a whole.

Penelitian ini bertujuan untuk mengetahui dampak dari kredibilitas seorang influencer di media sosial terhadap niat beli pakaian pada merek lokal di Indonesia. Adapun kredibilitas dari influencer dapat diukur dengan tiga variabel, yaitu trustworthiness, Expertise dan attractiveness. Penelitian ini menggunakan metode survei melalui kuesioner dan pengumpulan data dari para pengguna Instagram yang mengikuti akun sosial media influencer. Variabel yang diukur adalah kepercayaan (trustworthiness), keahlian (expertise), daya tarik (attractiveness), keterlibatan konsumen (consumers’ engagement), dan niat beli konsumen (customers’ purchase intention). Hasil dari penelitian ini menunjukan bahwa trustwothiness secara signifikan mempengaruhi minat beli konsumen terhadap produk pakaian merek lokal. Sedangkan, pada variabel daya tarik dan keahlian tidak mempengaruhi niat beli terhadap pakaian jadi merek lokal secara signifikan. Pada variabel keterlibatan konsumen memoderasi hubungan antara keahlian dan niat beli terhadap pakaian merek lokal. Namun sebaliknya, pada variabel keterlibatan konsumen tidak memoderasi hubungan antara kepercayaan dengan niat beli terhadap pakaian merek lokal, dan juga tidak memoderasi hubungan antara variabel daya tarik terhadap niat beli pakaian merek lokal. Dengan penelitian ini, diharapkan dapat memberikan wawasan bagi para produsen supaya dapat mengembangkan strategi pemasaran influencer yang tepat dan efektif sehingga dapat meningkatkan niat beli konsumen terhadap pakaian merek lokal.

The purpose of present study was to compare the effects of desflurane and sevoflurane on blood viscosity in three different shear rates and plasma viscosity. Forty male patients, ASAI-II, undergone tympanoplasty were included in this study. Patients were randomly categorized as anaesthetized either with sevoflurane or desflurane. Anaesthesia was maintained with inspiratory concentrations of sevoflurane 1-1.5 MAC or desflurane. The samples were taken for hemorheological and biochemical examinations before induction of anaesthesia (initial time) and at 60thand 120th min of the operation. Blood viscosities were measured by rotational viscometer. Plasma viscosity was measured by capillary viscometer. Patients receiving desflurane showed steady decrease at 23 1/sec shear rate at 60th and 120th min and in blood viscosity at 115 1/sec shear rate in 120th min. Statistically significant decrease in the level of plasma viscosity was observed in the patient group anesthetized with desflurane, between initial time vs 60th min (p<0.01), initial time vs 120th min. (p<0.01). Desflurane produced stable effects on the blood circulation. The differences in the blood viscosity should not be overlooked.

Introduction: Intoxication with organophosphate compounds used for pest control is common in Turkey. Organophosphate intoxication may occur during agricultural spraying, transport of organophosphate compounds, or domestic accidents, although suicide attempts are the most common way of intoxication.
Case Presentation: We present a 23-year-old woman ingested a fistful of painkillers and drank a sip of an unknown syrup after having a quarrel with her family. Four hours later, she had been taken to a nearby hospital with nausea, vomiting, and abdominal pain, where she had been treated for drug intoxication at an intensive care unit for 2 days and discharged uneventfully. About 18 days after drug intoxication she began noticing headache and weakness and numbness in her arms and legs. A detailed patient history taken in the emergency department indicated that the syrup she had taken for suicidal purpose was an organophosphate compound. An organophosphate –induced polyneuropathy was primarily considered.
Conclusions: In intoxication cases, package of the ingested compound should be inspected to determine the culprit molecule whenever possible. Organophosphate intoxication should always be remembered in the differential diagnosis of intoxication cases even when no specific compound could be determined since suicidal attempts with agricultural pesticide compounds are common in Turkey.
Susac’s syndrome : 2 cases without hearing loss

Published: February 2025

Susac’s syndrome is a disease of the microvasculature in the brain, inner ear (cochlea and vestibular apparatus) and retina that consists of a clinical triad of encephalopathy, hearing loss and visual disturbance. It is usually seen in young women. It is first defined by Susac et al. in 1979. Diagnosis is often difficult because the classic triad may take up to 2 years to develop and radiological findings are easily confused with multiple sclerosis. Also, encephalopathy may mask some other findings. We present two cases that we think are particularly instructive because they were male patients, had somewhat unusual presenting symptoms, had no accompanying hearing loss, required relatively less aggressive and less sustained immunosuppression than usual, and followed a relatively short and benign course, without relapse and with excellent outcome. They also serve as good examples of the apparent efficacy and sufficiency (in their cases) of IVIG
