Today, the world is fighting against a dangerous epidemic caused by the novel coronavirus, also known as COVID-19. All have been impacted and countries are trying to recover from the social, economic, and health devastations of COVID-19. Recent epidemiology research has concentrated on using different prediction models to estimate the numbers of infected, recovered, and deceased cases around the world. This study is primarily focused on evaluating two common prediction models Susceptible - Infected - Recovered (SIR) and Susceptible - Exposed - Infected - Recovered (SEIR). The SIR and SEIR models were compared in estimating the outbreak and identifying the better fitting model for forecasting future spread in Kuwait. Based on the results of the comparison, the SEIR model was selected for predicting COVID-19 infected, recovered, and cumulative cases. The data needed for estimation was collected from official sites of the Kuwait Government between 24 February and 1 December 2020. This study presents estimated values for peak dates and expected eradication of COVID-19 in Kuwait. The proposed estimation model is simulated using the Python Programming language on the collected data. The simulation was performed with various basic reproduction numbers (between 5.2 and 3), the initial exposed population, and the incubation rate. The results show that the SEIR model was better suited than the SIR model for predicting both infection and recovery cases with R 0 values ranging from 3 to 4, E 0 = 80 and α = 0.2 .Coronavirus disease 2019 (COVID-19) is caused by a Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2), which is a positive-strand RNA virus. The SARS-CoV-2 genome and its association to SAR-CoV-1 vary from ca. 66 to 96% depending on the type of betacoronavirideae family members. With several drugs, viz. chloroquine, hydroxychloroquine, ivermectin, artemisinin, remdesivir, azithromycin considered for clinical trials, there has been an inherent need to find distinctive antiviral mechanisms of these drugs. Curcumin, a natural bioactive molecule has been shown to have therapeutic potential for various diseases, and its effect on COVID-19 is also currently being explored. In this study, we show the binding potential of curcumin targeted to a variety of SARS-CoV-2 proteins, viz. spike glycoproteins (PDB ID 6VYB), nucleocapsid phosphoprotein (PDB ID 6VYO), spike protein-ACE2 (PDB ID 6M17) along with nsp10 (PDB ID 6W4H) and RNA dependent RNA polymerase (PDB ID 6M71) structures. Furthermore, representative docking complexes were validated using molecular dynamics simulations and mechanistic studies at 100 ns was carried on nucleocapsid and nsp10 proteins with curcumin complexes which resulted in stable and efficient binding energies and correlated with that of docked binding energies of the complexes. Both the docking and simulation studies indicate that curcumin has the potential as an antiviral against COVID-19.SARS-CoV-2 (COVID-19) spreads and develops quickly worldwide as a new global crisis which has left deep socio-economic damage and massive human mortality. This virus accounts for the ongoing outbreak and forces an urgent need to improve antiviral therapeutics and targeted diagnosing tools. Researchers have been working to find a new drug to combat the virus since the outbreak started in late 2019, but there are currently no successful drugs to control the SARS-CoV-2, which makes the situation riskier. Very recently, new variant of SARS-CoV-2 is identified in many countries which make the situation very critical. No successful treatment has yet been shown although enormous international commitment to combat this pandemic and the start of different clinical trials. Nanomedicine has outstanding potential to solve several specific health issues, like viruses, which are regarded a significant medical issue. In this review, we presented an up-to-date drug design strategy against SARS-CoV-2, including the development of novel drugs and repurposed product potentials were useful, and successful drugs discovery is a constant requirement. The use of nanomaterials in treatment against SARS-CoV-2 and their use as carriers for the transport of the most frequently used antiviral therapeutics are discussed systematically here. We also addressed the possibilities of practical applications of nanoparticles to give the status of COVID-19 antiviral systems.
Malnutrition remains achallenging problem in hospitals, especially among geriatric patients. LDC7559 The background and causes are actually well known but still underestimated in clinical practice.

This study evaluated possible differences in rates of malnutrition risk and malnutrition in geriatric patients living at home and geriatric patients living in residential nursing homes. For this purpose, data from atotal of 4 surveys (3 times nutritionDay plus 1additional survey) were combined and evaluated. In this secondary analysis, 258patients 65years and older are included. Malnutrition risk is determined by the malnutrition universal screening tool (MUST) and malnutrition by the ESPEN criteria.

Of the patients 86.0% (
 = 222) live at home and 14.0% (
 = 36) in residential nursing homes. The patients living in nursing homes have a higher morbidity and need of care. Indicators for the increased morbidity are alarger number of nights spent in the clinic in the last 12months (mdn 10.0 vs. 5;
0.007), higher number of daily drug intake (mdn 9.0 vs.7.0;
0.002) and greater limitations in walking abilities (mdn 3.0 vs. 1.0;
 < 0.001). They are significant older (median 86.0 vs. 78.0;
 < 0.001) and show ahigher percentage of manifest malnutrition (35.7%;
 = 10 vs. 20.1%;
 = 40;
0.062).

Geriatric patients living at home and in residential nursing homes show high rates of malnutrition. Amalnutrition screening at the beginning and during hospital stay is urgently required in every case as this is the only way to identify those affected. In addition, regular screening in outpatient departments as well as in nursing homes is also necessary.

Investigations revealed a large, right-sided pleural effusion that was bloody on aspiration. A diagnosis of TES was one of the diagnoses entertained and eventually confirmed on finding evidence of pelvic endometriosis on laparotomy. The management of TES should include hormonal therapy, surgical management, or a combination of both.Dialysis disequilibrium syndrome (DDS) is a neurological complication that has been known to occur after hemodialysis (HD). In recent years, the prevalence of DDS has been low as the symptoms are widely recognized; hence, preventive therapies, such as the slow and gentle procedure for HD, are often administered before starting dialysis. However, once DDS occurs, it may cause seizures, coma, and even death in severe cases. Since there has been no established treatment, recognizing risk factors and preventing the syndrome is important. A 76-year-old man was admitted to our hospital due to exacerbation of chronic heart failure. He also had a history of chronic kidney disease and had consulted with his home doctor about the preparation for HD a month before admission. After treatment with diuretics, the symptoms ameliorated, but he experienced presyncope and malaise. Laboratory tests revealed acute anemia and a decrease in renal function. Upper gastrointestinal endoscopy revealed active bleeding from a gastric ulnjury and accumulation of blood urea may not correlate with the risk of the syndrome.Coronavirus disease 2019 (COVID-19) is associated with various cardiovascular manifestations, including myocarditis, myocardial infarction, and arrhythmias. A prothrombotic state is the primary underlying pathogenic mechanism. While cardiac arrhythmias manifest more commonly amongst critically ill COVID-19 populations, ventricular arrhythmias have been reported only in few cases. This report describes a case of a 95-year-old African American man with COVID-19, who developed sustained monomorphic ventricular tachycardia, which progressed to an electrical storm. The case highlights the importance of high clinical suspicion, early recognition of electrical abnormalities in patients with active COVID-19 infection, and its ability to precipitate fatal ventricular arrhythmia. Also, we provide a literature review on the electrical storm in COVID-19 patients, highlighting the pathophysiologic mechanisms and the management of this deadly arrhythmia.Pleomorphic xanthoastrocytoma (PXA) is an infrequent neoplasm that affects children less commonly than adults. In this case report, a four-year-old boy presented with focal seizures has diagnosed with this tumor in the frontal lobe. Complete surgical resection was achieved, and histopathological features of PXA grade II were observed. During follow-up, the patient showed improvement of the focal seizures. In spite of the pleomorphic features, the PXA had a favorable prognosis.Adenomyomatosis of the gallbladder is a benign condition, usually occurring in middle age, in which the epithelium of the gallbladder proliferates and the gallbladder wall thickens with the presence of Rokitansky-Aschoff sinuses (RAS). The diffuse form is an unusual subtype of adenomyomatosis. Herein, we describe a 17-year-old female who presented with dull and intermittent pain in the right hypochondriac region for more than a month. Ultrasound followed by magnetic resonance imaging showed marked diffuse gallbladder wall thickening. A gross cholecystectomy specimen showed a diffusely enlarged gallbladder. The final diagnosis of gallbladder adenomyomatosis (GA) was confirmed by the histopathologic appearance of muscular and epithelial hyperplasia, contributing to mural thickening with epithelial invaginations forming the pathognomonic intramural diverticula known as the RAS. This case highlights that the diffuse form of GA is uncommon and is often accompanied by chronic inflammation, sometimes requiring differential diagnosis from gallbladder malignancies, especially when there is no image showing a "comet tail" of cholesterol crystals in the wall.
Our aim was to evaluatethe clinical and electroencephalographic effects of brivaracetam (BRV) inpatients with drug-resistant focal epilepsy. BRVis a new antiepileptic drug (AED) with a high affinity for vesicle protein 2A (SV2A) and recently approved as adjunctive therapy for focal onset seizures.

In this observational study of six-month duration, BRV (50-200 mg) was administered to 76 patients with drug-resistant focal epilepsy, who were≥16-year-old and who suffered from daily, weekly, monthly and yearly recurrent seizures. At baseline and after six months of follow-up, we performed a neurological visit, neuropsychological tests Quality of life in epilepsy-31 (QOLIE31), Epworth Sleepiness Scale (ESS),Intrapersonal Emotional Quotient (IEQ) and an electroencephalogram (EEG; inspective and quantitative analysis). Twenty-four patients underwent an overnight switch from levetiracetam (LEV) to BRV.

Seizure frequency of the 54 patients remaining at six months was reduced >50% in 29.6% of cases (responders), <50% in 31.
