Published: February 2021

Abstract
In present era, with the availability of better health care facilities and understanding of health issues, women are experiencing longer life expectancy and using more gynecological services, so obviously there is increase in gynecological surgeries. Any surgical procedure carries risks of complications. The risk of postoperative complications depends on individual characteristics, including age, medical comorbidities, and functional status. The aim of study was to reduce rates of mortality/morbidity among women who undergo surgical gynecological intervention at Zagazig University Hospital. This study included 212 cases were retrived prospectively in a cross sectional study. They underwent gynecological interventions. Our study group was 212 cases 24 cases ended with morbidity with percentage of 11.3% and 2 cases ended by death with percentage of 0.9% . This study shows that the most frequent complications among the studied group were septic wound infection (2.4%), bladder injury (2.4%), respiratory tract infection (1.9%),Venous thromboembolism(VTE) (1.9%) and GIT injury (1.4%). This study explains that there were two mortality cases the first case died on table due to primary hemorrhage during hysterectomy operation as a result of great vessel injury and the other case died during hysterectomy operation due to venous thromboembolic catastrophe (Pulmonary embolism). During post-operative period, she developed hypoxia; therefore, she was referred to ICU. Unfortunately, the patient was diagnosed as pulmonary embolism; thus, she was admitted at ICU for 3 days, but she finally died. Conclusion With the availability of highly skilled personnel with improved surgical expertise, safe anesthesia and collaboration of other specialized medical personnel, the major complications and mortality rate will decrease, but the postoperative complications like, fever, respiratory tract infection, septic wound and DVT still frequent in a significant number of patients in our community, which brings about much distress to the patients.

Authors: Chavan Pradeep 
Published: February 2021

Abstract
The present study focused on the structural, morphological, optical and fluorescence properties of Ni 0.5-x Mg 0.5 Cu x Fe 2 O 4 (x = 0.0, 0.1, 0.3 and 0.5) nanoparticles synthesized by using auto combustion technique. The structural formation of the ferrite nanoparticles were confirmed by FTIR spectroscopic study. From FTIR spectra of the synthesized ferrite nanoparticles, metal ions are situated in two different sub lattices i.e. tetrahedral (A-site) and octahedral (B-site) in ferrites. The surface morphology and grain size of Cu substituted Ni-Mg ferrite nanoparticles were estimated from the micrographs of atomic force microscopy (AFM); the maximum grain size 54.69 nm was obtained. Spectra of UV-Visible absorption of the synthesized ferrite nanoparticles were carried-out by using UV-Vis spectrophotometry; the maximum absorption was observed at 418 nm. The energy band gap of ferrite nanoparticles has been estimated using UV-Vis absorption spectra; the energy band gap 3.50 eV was obtained. From the fluorescence emission spectroscopy of synthesized ferrite nanoparticles, the ferrite samples emit red colour in the region of 680 nm.

Abstract
Quaternary glasses with the composition 50SiO2 – 25TiO2 – 5La2O3 – (20-x) Na2O – xY2O3 where x: (0≤x≥10) were synthesized using the melt-quench technique. XRD examined the nature of prepared glasses. UV-spectroscopic of investigated glass system studied at room temperature. Both optical bandgap and refractive index of the present glass have been increased. The polarizability and basicity were determined. Thermal parameter values increased as Y2O3 increased. Under controlling heat, the glass-ceramic were prepared and confirmed using XRD. Glass-ceramics are examined using SEM to evaluate a microstructure. Ultrasonic velocities and elastic-moduli of glass-ceramic samples are increased because of the increase in internal energy. The role of Y2O3 modifier in the glass system is clearly demonstrated. Y2O3 also works as an excellent nucleating agent that can induce crystallizations, supporting in the creation of the sub-phase of glass-ceramics.

Published: February 2021

Abstract
Heat generated during the friction stir welding (FSW) process is of complex nature and plays a vital role in influencing the quality of the fabricated joints. In this experimental research, an thermo mechanical process model was formulated to estimate the values of peak temperatures generated during the employment of FSW tools with four different pin geometries (namely cylindrical, taper cylindrical, square and triangle) for joining of AZ80A Mg alloy flat plates, to understand their significant role in influencing the size of the grains, their mechanical strength and in the quality of the joints. The peak temperature values of the formulated thermo mechanical process model are found to be consistent with that of the actual experimental results and exhibited relatively very small variation It was observed that the joints fabricated by taper cylindrical pin geometry was found to possess very fine sized grains, due to the generation of ideal peak temperature (ie., 3480C which is nearly 81–82% of the melting temperature of AZ80A Workpiece).

Published: February 2021

Abstract
Objectives: We aimed to develop a model for predicting the 4-year risk of knee osteoarthritis (KOA) based on survey data obtained via a random, nationwide sample of Chinese individuals.Methods: Data was analyzed from 8,193 middle-aged and older adults included in the China Health and Retirement Longitudinal Study (CHARLS). The incident of symptomatic KOA was defined as participants who were free of symptomatic KOA at baseline (CHARLS2011) and diagnosed with symptomatic KOA at the 4-year follow-up (CHARLS2015). The effects of potential predictors on the incident of KOA were estimated using logistic regression models and the final model was internally validated using the bootstrapping technique. Model performance was assessed based on discrimination—area under the receiver operating characteristic curve (AUC), and calibration. Results: A total of 815 incidents of KOA were identified at the 4-year follow-up, resulting in a cumulative incidence of approximately 9.95%. The final multivariable model included age, sex, waist circumference, residential area, difficulty with activities of daily living (ADLs)/instrumental activities of daily living (IADLs), history of hip fracture, depressive symptoms, number of chronic comorbidities, self-rated health status, and level of moderate physical activity (MPA). The risk model showed good discrimination with AUC = 0.719 (95% confidence interval [CI] 0.700–0.737), optimism-corrected AUC = 0.712 after bootstrap validation. A satisfactory agreement was observed between the observed and predicted probability of incident symptomatic KOA. And a simple clinical score model was developed for quantifying the risk of KOA.Conclusion: Our prediction model may aid the early identification of individuals at the greatest risk of developing KOA within 4 years.

Authors: Ejerskov Cecilie , Raundahl Maj , Gregersen Pernille Axel , Handrup Mette Møller 
Published: February 2021

Abstract
BackgroundThe mosaic form of neurofibromatosis type 1 (NF1) is called mosaic NF1 (MNF1). No specific MNF1 follow-up guidelines exist. It is debatable if patients with MNF1 should be clinically examined and undergo follow-up in accordance with the standard NF1 guidelines, as MNF1 patients more often may develop more benign phenotypes and thereby less disease-associated complications including cognitive impairment. We discussed the need for a specific MNF1 follow-up guideline with focus on frequency of plexiform neurofibromas and NF1-associated complications.MethodA systematic retrospective data collection in a MNF1 cohort from one of two Danish national centers of NF1 Expertise was completed. Data collected included demographics, clinical features including NF1 diagnostic criteria and NF1-associated complications. Recent literature in the field was reviewed.ResultsWe identified 17 patients with MNF1 with a median age of 37 years [4; 66]. Eleven (65%) were females. Five patients (30%) had a plexiform neurofibroma. The median age at detection of plexiform neurofibroma was 30 years [14; 60]. Nine (53%) had at least one NF1-related complication; scoliosis, hypertension, ADHD, learning disability, language delay, autism and delay in gross and fine motor function development. We reviewed nine articles. In total, 126 cases were described within three case-series. Nineteen (15%) had a plexiform neurofibroma and in total, 23 NF1-associated complications were reported including language delay, learning disability and skeletal abnormalities. Furthermore, from the literature it was evident that the diagnosing of MNF1 varies among physicians and across countries. ConclusionPatients with MNF1 present with plexiform neurofibromas and other NF1-related complications with a frequency requiring that follow-up of MNF1 patients should be in accordance with the standard NF1 guideline in both childhood and adulthood. Physicians should be aware of cognitive impairment as a complication to MNF1. To develop a specific MNF1 follow-up guideline, there is a need for an international consensus on the diagnostic criteria for MNF1 and a follow-up study conducted in a larger MNF1 cohort.

Authors: Trung Do Duc , Nguyen Nhu-Tung , Van Duc Duong 
Published: February 2021

In this study, the multi-objective optimization problem of turning process was successfully solved by a Taguchi combination method and MOORA techniques. In external turning process of EN 10503 steel, surface grinding process, the orthogonal Taguchi L9 matrix was selected to design the experimental matrix with four input parameters namely insert nose radius, cutting velocity, feed rate, and depth of cut. The parameters that were chosen as the evaluation criteria of the machining process were the surface roughness (Ra), the cutting force amplitudes in X, Y, Z directions, and the material removal rate (MRR). Using Taguchi method and MOORA technique, the optimized results of the cutting parameters were determined to obtain the minimum values of surface roughness and cutting force amplitudes in X, Y, Z directions, and maximum value of MRR. These optimal values of insert nose radius, cutting velocity, feed rate, and cutting depth were 1.2 mm, 76.82 m/min, 0.194 mm/rev, and 0.15 mm, respectively. Corresponding to these optimal values of the input parameters, the surface roughness, cutting force amplitudes in X, Y, Z directions, and material removal rate were 0.675 µm, 124.969 N, 40.545 N, 164.206 N, and 38.130 mm3/s, respectively. The proposed method in this study can be applied to improve the quality and effectiveness of turning processes by improving the surface quality, reducing the cutting force amplitudes, and increasing the material removal rate. Finally, the research direction was also proposed in this study
Enhancing the Li+ Diffusion in Li3VO4 by Coupling with Reduced
Graphene Oxide for Lithium-Ion Batteries
Authors: Guo Mingxuan , Li Haibo 
Published: February 2021

Background:
Owing to the excellent theoretical specific capacity and safety intercalation
potential, Li3VO4 (LVO) has been proposed as an advanced anode material for lithium ions batteries
(LIBs). However, the LVO suffers from low electronic conductivity that limits its commercialization.

Objective:
The reduced graphene oxide (rGO) is recommended to couple with micro-LVO particles
aiming to enhance the conductivity of composite electrodes.

Method:
The LVO@rGO composite is synthesized by a facile hydrothermal method. The morphology,
crystallinity, valance state and electrochemical behavior of LVO@rGO are characterized by
scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and electrochemical
workstation, respectively. Further, the LIBs’ performance is explored by making a coins-type
half-cell LIBs battery via battery system.

Results:
The Li+ diffusion rate of the optimized LVO@rGO electrode is 7.67×10-23 cm2/s, which
improves two orders of magnitudes of pure LVO electrode. As a result, the LVO@rGO anode delivers
a reversible capacity of 190.1 mAh/g at 0.1 A/g after 100 cycles, which is even twice higher than
that of pure LVO anode (90.6 mAh/g). Besides, it exhibits superior rate capability, i.e. a reversible
capability of 285.0, 220.2, 158.7, 105.2 and 71.7 mAh/g at 0.05, 0.1, 0.2, 0.5 and 1.0 A/g, respectively.

Conclusion:
The high conductivity and flexible texture enable rGO an idea building block to enhance
the Li ion diffusion of whole electrode. On the other hand, it is instrumental in alleviating the
aggregation of host materials, leading to high specific surface and specific capacity.

Authors: Sheng Xia , Zhu Pengfei , Zhao Yi , Zhang Jinwei , Li Haijia , Zhao Huan , Qin Jianmin 
Published: February 2021

Background:
Autophagy plays a “double-edged sword” in the process of tumorigenesis,
development and metastasis.

Objective:
In this study, we explored the effect of PI3K/AKT/mTOR autophagy-related signaling
pathway on regulating and controlling the invasion and metastasis of liver cancer cells by Bufalin.

Methods:
The cell counting, migration, adhesion and invasion assay were used to evaluate the effect
of Bufalin on cell proliferation, invasion and metastasis. The protein expression of PI3K/AKT/
mTOR signaling pathway were detected by the Western Blotting technique.

Results:
After inhibiting autophagy of HCC-LM3 cells, the inhibitory effect of Bufalin on adhesion,
migration and invasion of HCC-LM3 cells was significantly enhanced. Synergistic inhibition
was strongest when different autophagy inhibitors were combined with 3MA and CQ. After inhibiting
autophagy, Bufalin significantly inhibited the protein expression of P-AKT, Cyclin D1, MMP-
2, MMP-9 and VEGF in HCC-LM3 cells. The protein expression of PTEN and E-Cadherin in
HCC-LM3 cells was significantly increased.

Conclusion:
The present study shows that the anti-tumor effect of Bufalin mainly inhibit proliferation,
extracellular matrix degradation and angiogenesis of HCC by influencing autophagy. These
findings confirm the capability of Bufalin in inhibiting metastasis of HCC and in parallel to current
patents, could be applied as a novel therapeutic strategy in the prevention of metastasis of HCC.

Published: February 2021

Introduction:
Today, we see advances in the use of medicinal plants in the treatment of
fungal infections. Curcumin has major antimicrobial, antifungal, antimutagenic, and anticancer activities.
This systematic review study is designed to evaluate the effectiveness of curcumin on a dermatophyte
fungus, Trichophyton spp.

Methods:
In this study, antifungal effects of curcumin on the different strains of Trichophyton
were evaluated. For this reason, several databases, including PubMed, Scopus, Web of Science,
Embase and Google Scholar were searched systematically in years from1995 to 2020. Only articles
with at least English abstracts were evaluated. The syntax was constructed with the combination of
some keywords along with specific tags used for each of the databases.

Results:
In this systematic review, studies showed that curcumin has a potent effect on the inhibition
of Trichophyton growth. Of the 2,500 studies in the search step, only 11articleswere eligible
for the survey, 6 of which were on T.rubrum, 3 on T. mentagrophytes, 1 on both T. mentagrophyte
and T. rubrum, and 1 on T. longifusus.

Conclusion:
Today, due to an increase in drug resistance to antifungal agents, plant extracts can be
a good alternative in controlling fungal diseases. Curcumin and its compounds are effective in inhibiting
or reducing Trichophyton infections in vitro and in vivo.

Authors: North Frederick , Nelson Elissa M , Majerus Rebecca J , Buss Rebecca J , Thompson Matthew C , Crum Brian A 
Published: February 2021

BackgroundWeb-booking of flights, hotels, and sports events has become commonplace in the travel and entertainment industry, but self-scheduling of health care appointments on the web is not yet widely used. An electronic health record that integrates appointment scheduling and patient web-based access to medical records creates an opportunity for patient self-scheduling. The Mayo Clinic developed and implemented a feature in its Patient Online Services (POS) web and mobile platform that allows software-managed self-scheduling of well-child visits.ObjectiveThis study aims to examine the use of a new self-scheduling appointment feature within POS in both web and mobile formats and determine the use characteristics, outcomes, and efficiency of self-scheduling compared with staff scheduling.MethodsWithin a primary care setting, we collected 13 months of all appointment activity for the well-child visit for children aged 2-12 years. As these specific appointment types are for minors, self-scheduling is performed by parents or other proxies. We compared the appointment actions of scheduling and cancelling for both self-scheduled and staff-scheduled appointments. The frequency in which patients were using self-scheduling outside of normal business hours was quantified, and we compared no-show outcomes of finalized appointments.ResultsOf the 1099 patients who performed any self-scheduling actions, 73.1% (803/1099) exclusively used self-scheduling and self-cancelling software. For those with access to self-scheduling (patients registered with the Mayo Clinic POS), 4.92% (1201/24,417) of all well-child appointment-scheduling actions were self-scheduled. Staff scheduling required more than a single appointment step (eg, schedule, cancel, reschedule) in 28.32% (3729/13,168) compared with only 6.93% (53/765) of self-scheduled appointments (P<.001). Self-scheduling appointment actions took place outside of regular business hours 29.5% (354/1201) of the time. No-shows accounted for 3.07% (28/912) of the self-scheduled finalized appointments compared with 4.12% (693/16,828) of staff-scheduled appointments, which is a nonsignificant difference (P=.12). Staff-scheduled finalized appointments (that allowed for scheduling appointments for more than 12 weeks in the future) revealed a potential demand of 11.15% (1876/16,828) for appointments with longer lead times.ConclusionsSelf-scheduling can generate a significant number of finalized appointments, decreasing the need for staff scheduler time. We found that 29.5% (354/1201) of the self-scheduling activity took place outside of the usual staff scheduler hours, adding convenience value to the scheduling process. For exclusive self-schedulers, 93.1% (712/765) finalized the appointment in a single step. The no-show rates were not adversely affected by the self-scheduling.
