SUMMARY OBJECTIVE: Pathology in any segment of the spine-pelvis-lower extremity may impair the global postural balance, leading to compensatory alterations in other parts. The aim of this study was to compare the pelvic movements of patients suffering from knee osteoarthritis with patients who underwent total knee arthroplasty and healthy controls. METHODS: This study was performed at the Department of Orthopedics and Traumatology Clinic of a Cankiri State Hospital between April 2021 and February 2022. This study included 84 participants. Of them, 31 patients who underwent total knee arthroplasty between 2018 and 2020 years were selected as the total knee arthroplasty group, while 28 patients with knee osteoarthritis were selected as the knee osteoarthritis group. In the control group, there were 25 healthy individuals. Exclusion criteria from the study included any kind of neurological disease, an inability to walk a distance of 100 m unassisted, or a history of surgery to the lower limb. Pelvic movements (i.e., tilt, rotation, and obliquity) and gait parameters (i.e., “gait velocity,” “cadence,” and “stride length”) were assessed using a wireless tri-axial accelerometer. RESULTS: Total knee arthroplasty and control groups had decreased minimum anterior tilt of the pelvis, decreased maximum anterior tilt, and decreased oblique range of the pelvis compared with the knee osteoarthritis group. In comparison with the control group, gait velocity and length of stride during gait were remarkably lower in both knee osteoarthritis and total knee arthroplasty groups. CONCLUSION: In this study, total knee arthroplasty was found to affect pelvic movements. It was thought that total knee arthroplasty changed these variables, probably owing to the frontal and sagittal plane alignment correction through surgery.

Abstract Background and objectives The Beach Chair Position (BCP) has many advantages such as less neurovascular injury and better intra-articular visualization, but it has also negative consequences, including hemodynamic instability. Although maintaining normal Mean Arterial Pressure (MAP) is important, fluid management is also a crucial concept for hemodynamic stability. The main objective of this study is whether preloading before positioning would be effective for less hemodynamic instability. Methods This randomized, controlled study was conducted in a single center in the Istanbul University, Istanbul Faculty of Medicine. Forty-nine patients undergoing elective arthroscopic surgery in the BCP were recruited. In the study group, crystalloid fluid at 10 mL.kg-1 of ideal body weight was administered intravenously 30 min before the BCP for preloading. The primary outcome measures were differences of hemodynamic variables as MAP, Stroke Volume (SV), Heart Rate (HR), and Cardiac Output (CO). The secondary outcome measures were Postoperative Nausea and Vomiting (PONV) rates in postoperative first day, surgical satisfaction scale, total ephedrine dose used during surgery, and total amount of fluid. Results The MAP, CO, and SV measurements of the study group were higher than those of the control group in the 5th minute after the BCP (respectively, p= 0.001, p= 0.016, p= 0.01). The total amount of crystalloid and surgical satisfaction scales were higher in the study group (respectively, p= 0.016, p= 0.001). Total amount of colloid and ephedrine dose used in the intraoperative period, and PONV rates were lower in the study group (p= 0.003, p= 0.018, p= 0.019, respectively). Conclusion Consequently, preloading can be favorable approach to preserve hemodynamic stability.

Abstract Background: Erector spinae plane block (ESPB) is a recently described block. In many reports, ESPB has been reported to provide effective postoperative analgesia in patients undergoing cesarean delivery (CD). Herein, we compared the effectiveness of ESPB and control group in postoperative analgesia in patients undergoing CD under spinal anesthesia. Method: This assessor-blinded, prospective, randomized, efficiency study was conducted in the postoperative recovery room and ward at a tertiary university hospital. Eighty-six patients ASA II–III were recruited. Following exclusion, 80 patients were randomized into two equal groups (block and control group). Standard multimodal analgesia was performed in the control group while ESPB block was performed in the intervention (ESPB) group. Opioid consumption was measured and pain intensity between groups was compared using Numeric Rating Scores (NRS). Results: NRS was lower in Group ESPB at 3rd and 6th hours. There was no difference between NRS scores at other hours. Opioid consumption was lower in Group ESPB. Conclusion: When added to multimodal analgesia, bilateral ultrasound guided low thoracic ESPB leads to improve the quality of analgesia in the first 24 hours in patients undergoing CD.

Abstract Background In daily practice, atopic patients and those who have other drug allergies are referred to allergy clinics for evaluation of possible general anesthetic allergy despite the fact that it is not recommended in recent guidelines. Objective The aim of this prospective study is to determine the negative predictive value of skin tests for common general anesthetic drugs prior to general anesthesia in atopic patients and in patients who had drug allergies by including the data of those who had previously tolerated or reacted to general anesthesia. Methods A database program was constituted to collect the preoperative skin test data of patients referred to our clinic between 2013 and 2018. Demographic and clinical history, medications implemented during perioperative period, reactions, and results of skin tests performed with anesthetic drugs and latex were evaluated. Results Four hundred fifty-nine out of the total 1167 patients referred fulfilled the inclusion criteria for further evaluation. Nearly 75% of the patients were female and mean age was 46.3 ± 14.3 years. History of hypersensitivity reactions (HRs) due to NSAIDs and/or antibiotics, radiocontrast agents, local anesthetics, and food were present in the 53.1%, 4.1%, 1.5%, and 2.0%, respectively. The negative predictive values of skin tests for general anesthetics were in the range of 80-100%. Only 4 patients (0,87%) experienced HRs during operation. Conclusion These real-life data reveal high rates of negative predictive value of skin tests with general anesthetic drugs and a low reaction rate in atopic patients and in patients with allergy to other drugs.

Abstract We theoretically analyze many fusion experimental data by using ten different density distributions of the 19F nucleus. The real potentials are obtained by means of the double folding model while the imaginary potentials are established as the Woods-Saxon potential. The theoretical results are compared with the results calculated over one-dimensional Wong formula as well as the experimental data. Thus, alternative density distributions are proposed for the analysis of the experimental data of the 19F fusion reactions. Additionally, the barrier positions and heights of all the analyzed fusion reactions are calculated for all the density distributions and new analytical expressions for these results are derived. Finally, new pocket formulas giving the imaginary potential depths for fusion cross-section calculations with 19F are obtained for the first time.

ABSTRACT In March 2020, there were 118000 cases of COVID-19 in 114 countries, and more than 4000 deaths from this disease; at that time, the World Health Organization declared it a pandemic. Although respiratory symptoms are clinically prevalent in the clinical manifestations of COVID-19, SARS-CoV-2 infection may also be responsible for the presence of cardiovascular disorders. On a global scale, there has been a significant decrease in seeking for medical attention by patients, over COVID-19-nonrelated disorders, due to the concern of acquiring the SARS-CoV-2 virus in the hospital environment. In order to draw attention to the importance of the timely search for medical assistance in patients with cardiovascular symptoms in times of such a pandemic, the following case is presented, which is the first to address this issue in Cuba.

RESUMEN En marzo de 2020 existían 118 000 casos de COVID-19 en 114 países y más de 4000 muertes por esta enfermedad; en ese momento la Organización Mundial de la Salud la declaró como una pandemia. Aunque los síntomas respiratorios dominan usualmente las manifestaciones clínicas de la COVID-19, la infección por el SARS-CoV-2 puede también ser responsable de la presencia de alteraciones cardiovasculares. A escala mundial ha ocurrido una disminución significativa de la búsqueda de atención médica por parte de los pacientes, con padecimientos no relacionados con la COVID-19, debido a la preocupación de adquirir la enfermedad viral (COVID-19) en el medio intrahospitalario. En aras de llamar la atención sobre la importancia de la búsqueda oportuna de asistencia médica en pacientes con síntomas cardiovasculares en tiempos de una pandemia como la COVID-19, se presenta el siguiente caso, el cual constituye el primero que trata este tema en el país.

Abstract The elastic scattering angular distributions of 32S projectile by 12C, 27Al, 40Ca, 48Ca, 48Ti, 58Ni, 63Cu, 64Ni, 76Ge, 96Mo and 100Mo targets over the energy range 83.3 - 180 MeV are analyzed in the framework of the double folding model based on the optical model. The real part of the optical model potential is obtained by using a double folding model for eight different density distributions of 32S, which consist of Ngo, SP, 2pF, G1, G2, S, 3pF, and HFB. The imaginary part of the optical model potential is accepted as the Woods-Saxon (WS) potential. The theoretical results successfully reproduce the experimental data over both a wide energy range and many target nuclei. Finally, simple and useful formulas that predict imaginary potential depths of each density are derived based on the elastic scattering results.

Abstract The fusion cross section of 9Li + 70Zn reaction is studied in an extensive manner within the framework of different theoretical approaches. For this purpose, three different methods which consist of proximity potentials, temperature dependent densities and temperature dependent nuclear potentials are used in order to determine the real part of the nuclear potential. The imaginary part is considered as Woods-Saxon potential. The calculated fusion cross sections are compared with the experimental data. The theoretical results describe the experimental data very well. It is seen that the applied approaches are different ways to study the reactions involving fusion cross sections.

Abstract The elastic scattering angular distributions of the weakly bound nucleus 8Li on 7Li, 9Be, 12C, 13C, 14N, 27Al, 51V, 58Ni, and 208Pb are analyzed at various incident energies. For this purpose, the real potential is generated for nine different density distributions of the 8Li nucleus by using the double folding within the optical model. The theoretical results are in good agreement with the experimental data. In our study, also, new and practical sets of imaginary potentials for the investigated densities are derived.

Abstract In this work, we examine the elastic scattering cross sections of 13C on 12C, 16O, 28Si and 208Pb target nuclei at different incident energies. For the first time, we apply six types of proximity potentials such as Broglia and Winther 1991 (BW 91), Aage Winther (AW 95), Christensen and Winther 1976 (CW 76), Bass 1973 (Bass 73), Bass 1977 (Bass 77) and Bass 1980 (Bass 80) in order to obtain the real part of the optical potential. The imaginary part is taken as the Woods-Saxon potential. Theoretical results are compared with each other as well as the experimental data.

Abstract In the present study, experiments were conducted to optimize sulfate removal efficiency with ettringite precipitation from landfill leachate using Response Surface Methodology (RSM) and Central Composite Design (CCD). The statistical analysis of the results showed that the operating parameters such as molar rates of Ca/SO4 and Al/SO4, and pH had a significant effect on sulfate removal efficiency. Aluminum hydroxide and calcium hydroxide were used for external sources of aluminum and calcium. The goodness of the model was checked by different criteria including the coefficient of determination (R2 = 0.94), p value (<0.0001), adequate precision (14.78), and coefficient of variance (7.30). The RSM results indicated that the fitted model could be appropriate to predict sulfate removal efficiency. A 55.7% maximum sulfate removal efficiency was obtained at pH 11.95 for 2.29 Ca/SO4 and 0.74 Al/SO4 molar ratios. Sulfate inhibition effects on treatment methods such as the anaerobic process decreased with increasing COD/SO4 ratio from 14:1 to 25:1 by ettringite precipitation.

ABSTRACT The purpose of this study was to determine the effects of in-ovo injection of a propolis water extract on hatchability, embryonic mortality, starter live performance, and livability of Japanese quails. In total, 500 fresh hatching eggs were randomly distributed into five treatment groups of 100 eggs per treatment with four replicates of 25 eggs each. On day 14 of incubation, eggs from group 1 were not injected (control), group 2 was injected with distilled water (water), group 3 was injected with 1% propolis water extract (1% propolis), group 4 was injected with 2% propolis water extract (2% propolis), and group 5 was injected with 3% propolis water extract (3% propolis). A completely randomized design was applied, and data were analyzed using the least-square methodology. Hatchability and embryonic mortality in the 2% propolis and 3% propolis treatment groups were significantly lower compared with the control group, but no significant differences were observed between the 1% propolis and control groups. There were no significant bodyweight gain, feed intake, feed conversion ratio, or livability differences among treatments. The results of this study demonstrated that in-ovo injection of propolis water extract, especially at doses of 2% and 3% propolis, had negative effects on hatchability and embryonic mortality, but 1% propolis had no detrimental effects on hatchability or embryonic mortality. In all treatment groups, propolis did not negatively affect body weight gain, feed intake, feed conversion ratio, or livability.
