Abstract

Amitriptyline has a long history of effectiveness in treating depression. Due to its side effects, which include oxidative stress and anticholinergic effects, it is used less frequently. Ashwagandha is a substantial herb that has anti-depressant, antioxidant properties. The aim of study is to evaluate the effects of ashwagandha and amitriptyline on the oxidative state of acetylcholine esterase in rat salivary glands. Four groups of rats were created. Distilled water was given to group I (control), and group II received amitriptyline (10 mg/kg) orally. Ashwagandha root extract (200 mg/kg) was given orally to group III, while similar doses of ashwagandha root extract and amitriptyline were given in combination to group IV. Rats from each group were sacrificed at (7 and 30 days). A blood samples were collected to measure the total antioxidant capacity (TAC). For measuring acetylcholine esterase enzyme, salivary gland tissues were dissected. TAC after 7 days of oral administration showed a nonsignificant difference between groups while, after 30 days there is a significant decrease in TAC in group II and IV in comparison with that of the control group. Following oral dosing for seven days, acetylcholine esterase measurements revealed an increase in group II and a decrease in group IV as compared to the control group. While after 30 days, all groups acetylcholine esterase enzyme levels significantly decreased when compared with the control group. It can be Concluded that, Amitriptyline causes oxidative stress and temporarily inhibits acetyl cholinesterase, which results in anticholinergic action. Ashwagandha has acetylcholine esterase inhibitory characteristics and mild salivary gland antioxidant benefits. [ABSTRACT FROM AUTHOR]

Abstract

ObjectivesPaediatric cancer is a leading cause of death for children. Children in low-income and middle-income countries (LMICs) were four times more likely to die than children in high-income countries (HICs). This study aimed to test the hypothesis that the COVID-19 pandemic had affected the delivery of healthcare services worldwide, and exacerbated the disparity in paediatric cancer outcomes between LMICs and HICs.DesignA multicentre, international, collaborative cohort study.Setting91 hospitals and cancer centres in 39 countries providing cancer treatment to paediatric patients between March and December 2020.ParticipantsPatients were included if they were under the age of 18 years, and newly diagnosed with or undergoing active cancer treatment for Acute lymphoblastic leukaemia, non-Hodgkin’s lymphoma, Hodgkin lymphoma, Wilms’ tumour, sarcoma, retinoblastoma, gliomas, medulloblastomas or neuroblastomas, in keeping with the WHO Global Initiative for Childhood Cancer.Main outcome measureAll-cause mortality at 30 days and 90 days.Results1660 patients were recruited. 219 children had changes to their treatment due to the pandemic. Patients in LMICs were primarily affected (n=182/219, 83.1%). Relative to patients with paediatric cancer in HICs, patients with paediatric cancer in LMICs had 12.1 (95% CI 2.93 to 50.3) and 7.9 (95% CI 3.2 to 19.7) times the odds of death at 30 days and 90 days, respectively, after presentation during the COVID-19 pandemic (pConclusionsThe COVID-19 pandemic has affected paediatric oncology service provision. It has disproportionately affected patients in LMICs, highlighting and compounding existing disparities in healthcare systems globally that need addressing urgently. However, many patients with paediatric cancer continued to receive their normal standard of care. This speaks to the adaptability and resilience of healthcare systems and healthcare workers globally.

Abstract

Since the beginning of the 21st century the world had to face several outbreaks ofviral diseases like Chikungunya, Ebola, Nipah, H7H9 Bird flu, H1N1, SARS, MERS and above all the Coronavirus or SARS-CoV-2 which has brought the whole world to a standstill, as of now it as infected around 200 million people and has caused over 4 million deaths. The countries of USA, India, Brazil and Russia have been the most seriously affected countries of all. outbreak of Covid-19 a 'Public Health Emergency of International Concern' on 30th January 2020 and a 'pandemic' on 11th march 2020. Although the SARS-CoV-2 (Severe acute respiratory syndrome Coronavirus 2) or the Coronavirus has a very low fatality rate i.e. 2.9%, but the most problematic aspect of the Coronavirus is its unusually high infectivity rate. Such unique attributes of the virus called for more stringent and advanced methods of investigation, research and analysis and this is where Artificial Intelligence (AI) comes in; the scientific community strongly believe that AI and data science can be used to fight against the Coronavirus and can fill in the blanks still left by science. In current study of approach, we have emphasis the role of AI during the pandemic and implemented the study. Further, a trend analysis is conducted from year 2020 till 2021 to analyze the pattern for future forecasting.

Abstract

The effect of illumination energy on the electrical parameters of a monocrystalline silicon solar module was investigated and results used to reveal the effective spectrum which can help in generating the optimum power and photovoltaic effect. The current-voltage (I-V) characteristics of the device were measured under different illumination energies. Results showed that the ideality factor (n), series resistance (Rs) and saturation current (Io) are mostly dependent on the illumination energy, while the shunt resistance (Rsh) and photocurrent (Iph) are illumination intensity-dependent. The increase in illumination energy led to decrease in the series resistance but increase in the saturation current and ideality factor. On the other hand, the increase in illumination intensity resulted in increasing the shunt resistance and open circuit voltage. The study is important to understand the effective solar spectrum in producing the optimum photovoltaic performance, which can be also useful to interpret the photodetectors and photodiodes response to a specific spectrum.

Abstract

Objective: To present the first Egyptian clinical practice guideline for kidney transplantation (KT). Methods: A panel of multidisciplinary subspecialties related to KT prepared this document. The sources of information included updates of six international guidelines, and review of several relevant international and Egyptian publications. All statements were graded according to the strength of clinical practice recommendation and the level of evidence. All recommendations were discussed by the panel members who represented most of the licensed Egyptian centres practicing KT. Results: Recommendations were given on preparation, surgical techniques and surgical complications of both donors and recipients. A special emphasis was made on the recipient’s journey with immunosuppression. It starts with setting the scene by covering the donor and recipient evaluations, medicolegal requirements, recipient’s protective vaccines, and risk assessment. It spans desensitisation and induction strategies to surgical approach and potential complications, options of maintenance immunosuppression, updated treatment of acute rejection and chemoprophylactic protocols. It ends with monitoring for potential complications of the recipient’s suppressed immunity and the short- and long-term complications of immunosuppressive drugs. It highlights the importance of individualisation of immunosuppression strategies consistent with pre-KT risk assessment. It emphasises the all-important role of anti-human leucocyte antigen antibodies, particularly the donor-specific antibodies (DSAs), in acute and chronic rejection, and eventual graft and patient survival. It addresses the place of DSAs across the recipient’s journey with his/her gift of life. Conclusion: This guideline introduces the first proposed standard of good clinical practice in the field of KT in Egypt.

Abstract

Objectives This study describes the initiation of the Dutch Lung Cancer Audit for Lung Oncology (DLCA-L) and reports the first results of three years of clinical auditing. Methods The initiation, dataset, and data quality of the DLCA-L are described. For the analyses, all patients registered from 2017 to 2019 were included. Descriptive statistics were used to assess the first outcomes of the DLCA-L, including results from quality indicators, patient- and tumor characteristics, and the real-world use of immunotherapy. Results The DLCA-L was initiated after the surgery and radiotherapy audit for lung cancer. In total, 33.788 NSCLC patients and 4.293 SCLC patients were registered in the DLCA-L from 2017 to 2019. Seventy-three (97 %) Dutch hospitals participated in the DLCA-L in 2019. The registry became nation-wide in 2020. The data quality improved over the years, with complete cases in 90 % of the NSCLC patients. In total, 15 quality indicators were established based on DLCA-L data to improve processes and clinical outcomes. An example of these quality indicators was brain imaging at diagnosis of stage III NSCLC patients, which increased from 80 % in 2017 to 90 % in 2019 and hospital variation was reduced. The DLCA-L provided data on immunotherapy use in stage IV NSCLC (n = 4.415) patients. These patients had a median age of 67 years and 11 % of the patients had an ECOG PS ≥ 2. The number of patients treated with immunotherapy in different hospitals varied between 2 patients to 163 patients per hospital. Conclusion The DLCA-L has become a valuable and complete data source with national coverage in 2020. A high number of registered patients and limited missing data resulted in better insights into hospital processes and outcomes of lung cancer care. Quality indicators were, with success, used to establish improvements and minimize hospital variation. The DLCA-L also provides hospitals real-world information on the use of (systemic) therapies.

Abstract

Background It was difficult to compare the outcome of partial nephrectomy among different studies due to the absence of standardized description of different renal masses. This problem led to the development of nephrometry scoring systems. R.E.N.A.L. is among the commonest nephrometry scoring systems; however, some studies failed to find any relation between R.E.N.A.L. with perioperative outcome. We evaluated our designed newly modified nephrometry score in prediction of outcome following partial nephrectomy and compared its predictability versus original R.E.N.A.L. Methods Fifty-one patients with cT1-2N0M0 renal masses amenable for partial nephrectomy were included prospectively. Different perioperative outcome variables were compared according to complexity level in R.E.N.A.L. and the newly modified nephrometry score. Results Clinical staging was T1a (21.6%), T1b (49%), T2a (25.5%), T2b (3.9%). Median R.E.N.A.L. was 9 (4–12). Hilar position and intrarenal pelvis were detected in 19.6% and 68.6%. Low, moderate and high complexity masses were found in 21.6%, 39.2% and 39.2%. Complications and rate of conversion to radical nephrectomy were 17 (33.3%) and 4 (7.8%). The only significantly affected variable (p = 0.039) by R.E.N.A.L. was rate of secondary intervention, but it was higher in low than in high complexity level. In the newly modified nephrometry score, complications (p = 0.037) and rate of positive surgical margin (p = 0.049) were significantly higher with increased complexity level. Although other variables (pelvi-calyceal system entry, operative time, blood loss, hemoglobin loss, blood transfusion and conversion to radical nephrectomy) did not show statistically significant difference according to both scores, they were better associated with the complexity level in the newly modified nephrometry score with their remarkable increase in the high when compared to the low complexity level. Conclusions The newly modified nephrometry score was associated with better prediction of outcome of partial nephrectomy when compared to R.E.N.A.L.

Abstract

This paper presents a machine learning model to predict the effect of Al2O3 nanoparticle content on the coefficient of thermal expansion in Cu-Al2O3 nanocomposites prepared using an in situ chemical technique. The model developed is a modification of Long Short-Term Memory (LSTM) using dwarf mongoose optimization (DMO), which mimics the behavior of DMO to find its food for predicting the behavior of the composite. The swarm of DMO consists of three groups, namely the alpha group, scouts, and babysitters. Each group has its own behavior to capture the food. The preparation of the nanocomposite was performed using aluminum nitrate that was added to a solution containing scattered copper nitrate. After that, the powders of CuO and Al2O3 were obtained, and the leftover liquid was removed using thermal treatment at 850 °C for 1 h. The powders were consolidated using compaction and sintering processes. The impact of Al2O3 contents on the thermal properties of the Cu-Al2O3 nanocomposite was investigated. The results showed that the Thermal Expansion Coefficient (TEC) decreases with increasing Al2O3 content due to the increased precipitation of Al2O3 nanoparticles at the grain boundaries of the Cu matrix. Moreover, the good interfacial bonding between Al2O3 and the Cu may participate in this decrease in TEC. The proposed machine learning model was able to predict the TEC of all the produced composites with different Al2O3 content and was tested at different temperatures with very good accuracy, reaching 99%.

Abstract

IntroductionChildhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality.MethodsProspective cohort study in 109 institutions in 41 countries. Inclusion criteria: children ResultsAll-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3–11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); pConclusionsChildren with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer.

Abstract

Background: Many studies have compared real-world clinical outcomes of immunotherapy in patients with metastatic non-small cell lung cancer (NSCLC) with reported outcomes data from pivotal trials. However, any differences observed could be only limitedly explored further for causation because of the unavailability of individual patient data (IPD) from trial participants. The present study aims to explore the additional benefit of comparison with IPD. Methods: This study compares progression free survival (PFS) and overall survival (OS) of metastatic NSCLC patients treated with second line nivolumab in real-world clinical practice (n = 141) with IPD from participants in the Checkmate-057 clinical trial (n = 292). Univariate and multivariate Cox proportional hazards models were used to construct HRs for real-world practice versus clinical trial. Results: Real-world patients were older (64 vs. 61 years), had more often ECOG PS ≥ 2 (5 vs. 0%) and were less often treated with subsequent anti-cancer treatment (28.4 vs. 42.5%) compared to trial patients. The median PFS in real-world patients was longer (3.84 (95%CI: 3.19-5.49) vs 2.30 (2.20-3.50) months) and the OS shorter than in trial participants (8.25 (6.93-13.2) vs. 12.2 (9.90-15.1) months). Adjustment with available patient characteristics, led to a shift in the hazard ratio (HR) for OS, but not for PFS (HRs from 1.13 (0.88-1.44) to 1.07 (0.83-1.38), and from 0.82 (0.66-1.03) to 0.79 (0.63-1.00), respectively). Conclusions: This study is an example how IPD from both real-world and trial patients can be applied to search for factors that could explain an efficacy-effectiveness gap. Making IPD from clinical trials available to the international research community allows this. [ABSTRACT FROM AUTHOR]

Abstract

Acetylcholinesterase is required as an enzyme to counteract the effects of acetylcholine. The aim of the study is to assess how amitriptyline and Ashwagandha affect the acetylcholinesterase gene in rat salivary glands. Forty healthy albino rats were divided randomly into four equal groups: Group I (control) received distilled water for 30 days. Group II received amitriptyline (10mg/kg) for 30 days. Group III received ashwagandha watery root extract (200mg/kg) orally for 30 days and Group IV received the combination of amitriptyline orally and ashwagandha root extract orally for 30 days. Rats in each group were sacrificed after day 30 and salivary glands were dissected for measurement of the acetylcholinesterase gene using a Polymerase Chain Reaction technique (PCR). Acetylcholinesterase gene measurements reveal an increase in groups treated with amitriptyline alone (1.55±0.11) and in the group treated with a combination of amitriptyline with Ashwagandha (1.92±0.16), in comparison with the control group. There were no discernible differences between the Ashwagandha treated group (1.073± 0.25) compared to the control group (0.76±0.19). In conclusion, Amitriptyline alone and, when combined with Ashwagandha cause transcription of the acetylcholinesterase gene. [ABSTRACT FROM AUTHOR]

Abstract

This study presents the method for optimal error tracking in position control for a servo pneumatic actuated robot grasper system using a new adjustable convergence rate prescribed performance control (ACR-PPC). It focuses on improving the feedback controller and the fractionalorder proportional-integral-derivative (FOPID) controller used for the position control of each robot's finger. Multiple features were considered such as tracking error, rising time, faster transient response with finite-time convergence, oscillation reduction, and pressure stabilization in the pneumatic system. Experiments were conducted using a single finger of a tri-finger pneumatic gripper (TPG) robot, actuated by a single proportional valve with a double-acting cylinder (PPVDC). Two types of input trajectories were tested: step and sine wave inputs, which are common and critical for pneumatic systems. The results show that the proposed method eliminates oscillation and achieves high tracking performance within the prescribed bounds and minimal overshoot as well. The oscillation was suppressed with minimal overshoot and fast response was achieved by tuning the formulated adjustable prescribe performance function, thus improving the rising time response without significant loss of performance.

The formulations were applied on the forearms of the 20 female volunteers (one forearm of each volunteer was left untreated as a control). The subjects stayed for 30 minutes in a conditioned room with their forearms uncovered to let the skin adapt to the temperature (22°C ± 2°C) and humidity (50% ± 2%) of the room. Skin hydration and skin occlusion were recorded at day one (before treatment) and day seven (after treatment). Three measurements for skin hydration and skin occlusion were performed in each testing area.Results: NLC formulations with the highest lipid concentration, highest solid lipid concentration, and additional propylene glycol (formulations A1, A2, and A5) showed higher physical stability than other formulations. The addition of propylene glycol into an NLC system helped to reduce the particle size of the NLC and enhanced its long-term physical stability. All the NLC formulations were found to significantly increase skin hydration compared to the untreated controls within 7 days. All NLC formulations exhibited occlusive properties as they reduced the transepidermal water loss within 7 days. This effect was more pronounced with the addition of propylene glycol or lecithin into an NLC formulation, whereby at least 60% reduction in transepidermal water loss was observed.Conclusion: NLCs with high lipid content, solid lipid content, phospholipid, and lecithin are a highly effective cosmetic delivery system for cosmetic topical applications that are designed to boost skin hydration.Keywords: nanostructured lipid carriers, transepidermal water loss, skin hydration, particle size

Abstract

In this work, the physical properties of calcium lithium borate glasses are investigated upon the inclusion of Cu+2 ion dopant. UV–Vis–NIR, photoluminescence, FTIR, and XRD techniques were, respectively, used in this study. From the optical absorption response of the samples, direct and indirect energy band gaps were calculated and they were found to be in the ranges of 3.57–3.28 eV and 3.78–3.6 eV, respectively. Results showed that the refractive index was increased from 2.258 to 2.326 with the increase in Cu2O concentration. Also, three main emission bands were observed in the luminescence spectra at around 399, 483, and 575 nm, which are correlated with the change in the copper concentration. Results of the FTIR spectroscopy showed various peaks in the ranges of 1383–1415 cm−1 and 1062–1076 cm−1, which can be attributed to the trigonal and tetrahedral stretching vibrations of BO3 and BO4 units.

Abstract

Background To assess patients undergoing radical cystectomy using enhanced recovery protocol and standard protocol in terms of intraoperative and postoperative outcomes and complications. Results All operative and postoperative complications were recorded. In group B, time to normal bowel activity ranged from 1 to 4 days, and the mean was 1.8 days (± 1.02), while it ranged from 1 to 5 days, and the mean was 3.17 days (± 1.14) in group A which was statistically significant (p value p value = 0.033). Postoperative mortality was similar in both groups. Conclusion In patients undergoing radical cystectomy, enhanced recovery protocol is considered as a safe procedure and not associated with any increase in intraoperative and postoperative complications compared to standard protocol. The length of hospital stay and time to return to full diet are reduced.

Abstract

The APPROACH cardiovascular surgical intensive care unit (CVICU) readmission score has excellent discrimination and calibration for CVICU readmission after discharge to a surgical ward; however, it has not been prospectively validated.In a prospective consecutive cohort of 805 patients ≥18 years admitted to the CVICU after coronary artery bypass and/or valvular surgery, the APPROACH CVICU readmission score was calculated at the time of discharge to a surgical ward. The study compared observed versus predicted CVICU readmission and the model discrimination was evaluated using AUC c-index. The incremental prognostic utility of 6 pre-specified prospectively collected respiratory (re-intubation, tracheostomy, oxygen at discharge) and hemodynamic variables (heart rate, systolic blood pressure, inotropes at discharge) were tested using net reclassification index (NRI) and integrated discrimination improvement (IDI).A total of 37 (4.6%) patients were readmitted to the CVICU. The median CVICU length of stay (9.0 vs 2.0 days, p .001) and all-cause in-hospital mortality (8.1% vs 0.4%, p .001) was higher among readmitted patients. The model had good discrimination (c-index = 0.748). Systolic blood pressure at discharge yielded the largest improvement in model discrimination (c-index = 0.782; Hosmer-Lemshow p = .749).In a prospective validation cohort, the APPROACH CVICU readmission risk score had good discrimination and could be operationalized in future research and clinical practice.
