Objective: The objective of the study was to measure the knowledge, attitudes and behaviors about Human Papilloma Virus (HPV) and HPV vaccine and to detect the HPV vaccination status of medical school students.
Materials and Methods: This descriptive cross-sectional study was conducted on students in a medical school. A sociodemographic data form and HPV Knowledge Scale were used in the study. A p-value of less than 0.05 was considered statistical significance, with a 95% CI.
Results: Of the 518 students who participated in the study, 57.9% were female, and 61.6% were preclinical students. Rates of smoking (p=0.018) and alcohol consumption (p=0.001) and sexual activity status (p<0.001) were significantly higher in male than in female students. Only 2.3% of participants reported having received the HPV vaccination. Age (p<0.001), gender (p=0.017), and nationality (p=0.045) were found to have a significant effect on student receipt of HPV vaccine. HPV knowledge level was higher among those who were female (p=0.004), studied in a clinical class (p<0.001), were sexually active (p<0.001), could easily talk about sexuality in the family (p=0.027), and had obtained their knowledge from medical school (p<0.001) and medical professionals outside of school (p<0.001).
Conclusion: The HPV knowledge level of medical students was moderate compared to the literature. Increasing the knowledge level of medical students is crucial as they can influence other peers through peer education. Therefore, efforts should be made to improve the knowledge level and vaccination rate in medical schools, both in the curriculum and in extracurricular activities.

Published: March 2023

Objective: Parasitic infections are more frequently observed in immunosuppressed cases, such as those infected with human immunodeficiency virus (HIV).
Furthermore, compared to immunocompetent cases, a more severe clinical course is observed in the immunosuppressed patient group. HIV-positive individuals have increased pathogenicity of parasites and may exhibit a wide range of clinical symptoms of varying severity that may result in mortality. Visceral
leishmaniasis (VL) is a vector-borne disease and an important opportunistic infection seen in HIV/Acquired Immune Deficiency Syndrome (AIDS) cases,
most notably in Southern Europe and Africa, where both infections are endemic. Several parasites namely toxoplasmosis, cryptosporidiosis, isosporiasis,
cyclosporiasis, amebiasis, giardiasis, plasmodium, and strongyloidiasis are infections posing significant risk factors for these patient groups.
Materials and Methods: In this study, visceral leishmaniasis was investigated serologically in serum samples and parasitic infections were analyzed by
conventional methods in fecal samples from HIV-positive cases.
Results: 5 of the 42 cases included in the study were female. The mean age of these cases was 38.7 years (19-66). Blastocystis spp was detected in 5 fecal
samples obtained from HIV-positive cases. The rK39 dipstick test with serum samples yielded a very weak band in one case, while none of the other tests
yielded a positive band.
Conclusion: The regional prevalence of these latent infections, which can be subclinical in HIV-positive patients, is important to know. However, the literature lacks sufficient data on the situation in Turkey. In this study, the prevalence of enteric parasitic infections in people with HIV infection in our region
was found to be low and VL was not detected.

Published: March 2023

Objective: For a long time immunomodulatory / immunosuppressive drugs have been used to slow the progression of multiple sclerosis (MS). These treatments are known to suppress the immune system and create susceptibility to infections. In our study, it was aimed to review the severity and frequency of COVID-19 disease in MS patients who received immunomodulatory/immunosuppressive treatments during the current coronavirus disease 2019 (COVID-19) pandemic, and also to evaluate whether they were adversely affected in terms of psychological outcomes.

Material and Methods: Participants consisted of MS patients who acquired COVID-19 (group 1) aged 18-65, using disease-modifying treatments (DMT) with follow-up in a neurology outpatient the clinic and the other two control groups consisted of similar ages and genders.
One of the other two groups is MS patients who have not had COVID-19 (group 2), the other group consisted of patients who had COVID-19 and did not have MS (group 3). MS profile, coronavirus anxiety scale (CAS), and Beck depression inventory (BDI) scales between groups 1 and 2; COVID-19 profile between groups 1 and 3 compared.

Results: As a result of comparing the MS disease profile of the 1st and 2nd groups and in terms of the COVID-19 disease profile of the 1st and 3rd groups, there was no statistically
a significant difference in these paired comparison groups (p> 0.05).

Conclusions: It was concluded that DMT use does not increase the severity of COVID-19 and having COVID-19 does not cause any additional changes in the psychiatric status of MS patients, since no a statistically significant difference was observed in the 2 MS group and 2 COVID-19 group comparison.

Authors: Shuai Y. , Maslovskaya A.G. , Kuttler C.
Published: March 2023

”Quorum sensing” as a special kind of communication in bacterial populations can be analyzed by means of methods and techniques of mathematical modeling and computer simulation. In the present study, a modification of a deterministic mathematical model of bacterial quorum sensing is proposed, taking into account the law of multiphase population dynamics. The mathematical model is formalized by an initial-boundary value problem for a system of semilinear reaction-diffusion partial differential equations. The equations include generation terms in view of changes in the biomass density. The model describes space-time dynamics of concentrations of special substances (signaling agents and Lactonase enzymes) that characterize the quorum sensing in Gram-negative bacteria. The problem is solved by means of the finite element method using the COMSOL Multiphysics platform. Computational experiments are performed to estimate concentrations of key substances characterizing quorum sensing for Pseudomonas putida bacterial strains in an expanded range of population dynamics.

Towards sustainable environmental goals, the utilization of agricultural waste as concrete material in the low-cost construction industry has received special interest from many researchers. It is the best approach in converting waste into valuable sustainable products which consequently reduces abundant of the waste and avoid environmental pollution. Literature proved that bamboo has high tensile strength and the mechanical properties of bamboo are almost similar to steel reinforcement, besides the advantage of its lightweight and cost-effective. In this study, a Systematic Literature Review (SLR) is conducted to review the behaviour of the bonding strength of bamboo reinforcement in concrete. The SLR is proposed based on the widely adopted review protocol named ‘Reporting standards for Systematic Evidence Syntheses’ (ROSES). The proposed SLR procedure is critically discussed, starting from the formulation of the research question until the process of data abstraction and analysis. Particular emphasis is given on the different types of behaviour of bonding strength developed in bamboo reinforced concrete based on results of the pull-out test. Different types and behaviour of bamboo bonding reinforcement are studied and discussed. The study highlights the mechanical properties of bamboo as an alternative reinforcement in concrete and types of bamboo reinforced structural components. This reviews also compared the methodology adopted for surface treatment and preparation of bamboo reinforcement.

This paper presents the parametric studies to obtain the optimum V-shaped angle plate due to blast load by using numerical simulations i.e., LS-DYNA. Constant magnitudes of mass of TNT and standoff distance were used while the angle of the V-shaped plate was varied in 5 °’ interval from 60 ° down to 10 °. This study found that the optimum V-shaped angle plate that could mitigate the maximum amount of blast load while experiencing minimal deformation at the vertex of the V-shaped plate was 25 °. Detailed parametric steps were presented in this study in order to arrive at the optimum angle of V-shaped plate to mitigate the blast load.

Soil erosion issue is common among construction sites. The phenomena usually takes place on sloped areas with no soil cover. The main objectives of the research are to determine the sediment concentration of rain induced on different types of covers and also to determine the hydraulic parameters. Besides that, the research also has to investigate the relation of the sediment concentration with hydraulic parameters. This research will take place in rainfall simulator using soil sample collected from sloped areas. The hydraulic parameters of this experiment consist of flow velocity, flow depth, shear stress, and unit stream power. Soil sample will be placed on four trays with different types of covers and properly arranged in the rainfall simulator with slope of 20 ᵒ. The sample will undergo rainfall event for two hours. The surface runoff collected and the sediment concentration measured using Total Suspended Solid (TSS) testing. The result shows the stream power of dry leaves is higher among those four covers with 0.0046 msˉ¹ followed by grass cover with 0.0033 msˉ¹ than gravel with 0.0023 msˉ¹, and lastly bare soil cover with 0.0008 msˉ¹. However, sediment concentration and surface runoff that were produced by bare soil is the highest followed by gravel, then leaves, and lastly grass. Generally, the sediment production in descending order started with the bare soil, gravel, dry leaves, and grass. From the research shown, rain induced on vegetation cover can be used as a low-cost initiative to control the soil erosion on construction slope area.
The (Un)Intended Consequences of Emphasizing the Threats of Mis- and Disinformation
Authors: Hameleers Michael
Published: March 2023

The mis- and disinformation order does not only consist of the dissemination of deceptive content but also involves using fake news as a blame-shifting label in politics and society. The salience of this label on social media and in political discourse, and the frequent discussions held about the threats of fake news in public opinion, may result in a systematic overestimation of mis- and disinformation’s presence. Even more so, these primed perceptions about false information may affect people’s evaluations of factually accurate information. In this article, we offer a theoretical account of how the public’s and media’s attention to mis- and disinformation, fake news labels, and the threats of mis- and disinformation may have a negative impact on people’s trust in factually accurate information and authentic news. In addition, relying on an experimental case study of pre-bunking interventions, we illustrate the extent to which tools intended to increase media literacy in the face of mis- and disinformation may also have ramifications for trust in reliable information. Based on this, we propose a forward-looking perspective and recommendations on how interventions can circumvent unintended consequences of flagging false information.

Non-organ retroperitoneal tumors are a heterogeneous group of malignant neoplasms that develop from different types of connective tissue, which in turn determines the variety of histological forms. More than 3,000 new cases of soft tissue sarcomas are registered an‑ nually in Russia, which is 1 % of all malignant neoplasms. In 2021, 3150 new cases of malignant neoplasms of connective and other soft tissues were detected for the first time. Retroperitoneal sarcomas account for 10–15 % of all types of soft tissue sarcomas. Diagnosis and treatment of non‑organ retroperitoneal tumors is an extremely difficult task. Non‑organ retroperitoneal tumors of mesenchymal origin are characterized by extremely rapid and aggressive growth. The prognosis of the disease is determined by the variant of the histological structure, the primary localization of the tumor, as well as timely and adequate treatment. Considering that non‑organ retroperitoneal tumors can metastasize to other organs in more than 30 % of cases, they are often detected at an advanced stage. Existing methods of radiation diagnostics and other research methods conducted within the framework of the examination standard, which can generally characterize the primary tumor of the retroperitoneal space, but in more than 60 % of cases give false positive information about the degree of tumor germination into neighboring organs and structures, especially into the main vessels. For this pathology, the main method of treatment is surgical. The long‑term results of surgical treatment and the expediency of palliative removal are currently insufficiently studied. Therefore, it is necessary to improve the methods of diagnosis and surgical treatment of non‑organ malignant tumors of the retroperitoneal space. Correct preoperative assessment of the prevalence and histological structure of the tumor allows you to choose an adequate amount of surgical intervention. This article presents a clinical observation of successful surgical treatment of a patient with solitary fibrous pelvic tumor.

Published: March 2023

The relevance of the problem of increasing the effectiveness of standard treatment of ovarian cancer is determined by the following characteristics of the disease: high one‑year mortality, high recurrence rate and unsatisfactory results of their treatment. Peritoneal carcinomatosis in ovarian cancer occurs in 65–70 % of cases. The standard modern approach to the treatment of ovarian cancer is a combination of surgical treatment and systemic intravenous chemotherapy. At the same time, more than 70 % of ovarian cancer cases are first diagnosed at stages III–IV. However, despite the successes in the field of surgery and drug treatment, the five‑year survival rate is no more than 24 % at the III and 4.6 % at the IV stage of the disease. One of the frontiers of ovarian cancer resistance to therapy is peritoneal carcinomatosis. Its resistance to therapy is due to the low bioavailability of cytostatics in metastases on the peritoneum to almost zero. In order to increase bioavailability, various forms of intra‑abdominal chemotherapy are used. The technique of pressurized intraperitoneal aerosol chemotherapy (PIPAC) has a number of advantages over other methods of intra‑abdominal antitumor treatment. These advantages include the uniform distribution of cytostatics over the peritoneum, the absence of penetration of cytostatics beyond the peritoneum, which allows PIPAC to be combined with systemic chemotherapy, low trauma and good tolerability of the procedure. PIPAC was implemented into clinical practice in 2011, and since then has been widely used in a number of foreign and domestic clinics. The conducted studies confirm the safety of the technique and its effectiveness against peritoneal carcinomatosis. The data of multicenter studies and the analysis of available literature data, as well as the successful own experience of PIPAC use create prerequisites for investigating the effectiveness of intra‑abdominal aerosol chemotherapy under pressure in relation to peritoneal carcinomatosis in ovarian cancer.

Introduction. As a result of the COVID-19 pandemic, the prevalence of stress, anxiety, depression, and alcohol consumption has increased among medical students. Mindfulness is an intervention to decrease these psychopathologies and alcohol consumption; however, evidence has shown unclear results regarding its efficacy. Objective. To evaluate the effectiveness of an online Mindfulness-based intervention (MBI) on stress, anxiety, and depression symptomatology levels, as well as on alcohol consumption and mindfulness status in medical students during the COVID-19 pandemic. Method. A quasi-experimental study was conducted on 237 students, obtaining sociodemographic data. In addition the levels of psychopathology, alcohol consumption, and state of mindfulness: were measured pre-and post-intervention through the DASS-21, AUDIT, and MASS instruments. Eight online Mindfulness sessions were conducted once a week for approximately one hour each. Results. MBI did not reduce levels of psychopathologies or alcohol consumption, nor did the mindfulness status improve. High levels of psychopathologies, dropout rate, and lack of voluntary participation were the main factors limiting the effectiveness of the online MBI. Discussion and conclusion. The online MBI wasn’t effective among the population under study: we recommend generation strategies where students are involved in and complete intervention programs. Results from this research will help enhance future online mindfulness interventions.

Published: March 2023

Introduction. University students experience multiple academic and social activities that cause enormous anxiety and stress, affecting them psychologically and physically. In this case, the psychosomatic symptoms, resulting from stress and anxiety, are part of a physical ailment and their emergence can be linked to the setting and time when they occur. Objective. To determine the association between anxiety levels and the degree of psychosomatic features (PF). Method. A study with a cross-sectional analytical design was developed, which included a total of 352 medical students from the city of Piura, Peru, to whom the PHQ-15 test was administered through Google Forms. Those with a previous psychiatric diagnosis were excluded. Results. It was found that PF are influenced by being female (RPa = 1.45, CI 95% = [1.23, 1.71], p ≤ .001), and having mild (RPa = 1.11, CI 95% = [1.20, 1.63], p ≤ .001) and moderate anxiety levels (RPa = 1.7, CI 95% = [1.24, 2.34], p = .001). Discussion and conclusion. The presence of a mental condition is necessary for the presence of PF. These stressors create selective alterations of large-scale brain networks involved in the cognitive control, regulation and processing of emotions, stress, and somatic-visceral perception. The study concludes that psychosomatic features are found in approximately 75% of medical students and anxiety in approximately 15%. Mild and moderate anxiety is an influential factor in psychosomatic features, as is being female.

This research aimed to describe the relationship between affect (positive and negative) and physical activity (PA) in college students during the COVID-19 pandemic. Method. A cross-sectional survey was conducted on health sciences students from three universities in Mexico and Colombia. PA was assessed using the short version of the International Physical Activity Questionnaire (IPAQ-S), and affects were measured using the PANAS index. A logistic regression model was used to assess the association between PA and affect. Results. We included 430 participants between 16 and 40 years. We found no differences between the male and female participants regarding age, weight (BMI), PA, or the number of hours of sitting per day. The monthly consumption of alcohol and tobacco was more frequent in males (p () .05), and women expressed having worse sleep quality (p () .05). Adjusting for the number of hours spent sitting per day, gender, BMI, age, sleep quality, smoking and alcohol consumption habits, participants reported having more positive affect when they engaged in greater PA. No association was found between PA and negative affect. Discussion and conclusion. Prioritizing mental health and assessments that determine the late impact of the COVID-19 pandemic on psychological well-being is critical. Promoting PA in university communities is considered a priority to positively impact students’ mental health and provide tools to facilitate coping.

This paper presents the research study using the HEC-RAS model to evaluate sediment dynamic problems in lower Nara canal pre and post-construction of fall structures at RD-77 and 101 respectively which is a major tributary of upper Nara canal that off-takes from Sukkur barrage on the left bank of Indus River. As a result, the hydraulic model has computed longitudinal and cross-section, velocity, water surface profiles, and sedimentation dynamics. Sediment transportation without fall structure is aggradation (5.75 ft and degradation (4.50 ft) and with fall structure aggradation (4.25 ft) and degradation (2.75 ft) respectively. Sediment transportation without fall structure is aggradation 500,000 tons and degradation 225,000 tons and with fall structure aggradation 155,000 tons and degradation 125,000 tons. Sediment transportation without fall structure is degradation 600,000 tons and with fall structure is aggradation 110,000 Tons and degradation 165,000 Tons. Sediment transportation without fall structure is aggradation 1,750,000 Tons and with fall structure is aggradation 1,300,000 Tons. Hence the results of the model revealed that aggradation at u/s and degradation at d/s of fall structures that is a true representation of the behavior of fall structures. Whereas, the section is wider than aggradation occurred and degradation is experienced in narrow sections in both scenarios (with and without fall structures). The positive impact of constructed fall structures was analyzed on the morphology of the canal. Hence, the construction of fall structures are essential at the change of country/steeper slope to avoid unnecessary erosion.
TheK−MSlope: A Potential Supplement forb-Value
Authors: Li Linxuan , Luo Gang , Liu Mian
Published: March 2023

The b-value of the Gutenberg–Richter law describes the relationship of size and frequency distribution of earthquakes. Its variations may be related to stress state, hence has been used for short-term earthquake forecasting. However, estimation of b-value faces many uncertainties, making it difficult to interpret b-value changes as tectonic signals or statistical artifacts. Some recent studies have suggested that the b-values of some seismic catalogs are proportional to the K−M slope (KMS) obtained from the visibility graph analysis. If confirmed, the KMS may provide additional constraints to the b-value and its variations. In this study, we used synthetic seismic catalogs that obey various probability distributions to demonstrate that the proportional relationship between KMS and b-value is universal and stable, and that the KMS/b ratio is dependent on the catalog size. We found that the KMS estimation can perform better than the commonly used b-value estimation methods, especially when the catalogs are incomplete or have variations in the magnitude–frequency relations. We proposed an improved KMS method to ensure that the KMS value provides pure magnitude information and is not affected by the occurrence time or orders of the events. We used the KMS to estimate the spatiotemporal variations of b-value in the northeastern Tibetan plateau; the results are consistent with those derived from traditional b-value estimation methods. We suggest that the KMS can be used as a verification of or a supplement to the b-value.

QUARTZ FIBER RADOME AND SUBSTRATE FOR AEROSPACE APPLICATIONS
Authors: BAKIR Mete
Published: March 2023

This study investigated the use of quartz fiber as an antenna radome and a dielectric substrate for a patch antenna designed to operate at f=8 GHz. To compare the performance of quartz fiber as an antenna radome, glass fiber is examined for the same antenna. For the substrate case, quartz fiber is compared with the well-known and widely used dielectric substrate, FR-4. The electromagnetic properties of the quartz fiber were examined for different temperature values using a free space measurement setup and a controllable furnace. The complex electrical permittivity (ε) values of glass and quartz fiber are measured using a free-space setup. The antenna parameters, including radiation pattern, gain, return loss, and beamwidth, are investigated and compared in detail for all cases to demonstrate the effects of the use of quartz fiber as a radome and an antenna substrate

La finalidad fue desarrollar y diseñar una máquina inyectora de plástico automatizada utilizando las herramientas FluidSIM, CADe SIMU y SketchUp. Asimismo, se encontró los principales elementos que componen el mecanismo y verificamos resultados mediante comparación de rendimiento y productividad. El diseño se realizó en base a especificaciones mediante el uso del software SketchUp. Con ello se controló el sistema de inyectado neumático y diseñó el circuito en el software FluidSIM, para de tal manera poder simularlo y validarlo. Además, con el propósito de diseñar el circuito eléctrico del motor y sensores se utilizó el software CADe SIMU. También se empleó datos obtenidos de la recolección y pesaje de plástico que realiza la Municipalidad Distrital de Víctor Larco Herrera en dicho distrito, lo que nos llevó a obtener una mejora frente a una máquina manual. Esto quedó evidenciado en el rendimiento y productividad las cuales pasarían de ser 75% y 28 botellas por minuto a ser de 97% y 37 botellas por minuto. El aplicar esta automatización está completamente justificada, ya que además de aumentar el rendimiento y productividad reduciendo los tiempos muertos en los que los operarios descansaban o tenían break, también mitigará la fatiga de estos en el trabajo, sin afectar negativamente la producción.
