Thromboembolic events (TEE) associated with atrial fibrillation (AF) are highly recurrent and usually severe, causing permanent disability or, even, death. Previous data consistently showed significantly lower TEE in anticoagulated patients. While warfarin, a vitamin K antagonist, is still used worldwide, direct-acting oral anticoagulants (DOACs) have shown noninferiority to warfarin in the prevention of TEE, and represent, to date, the preferred treatment. DOACs present favorable pharmacokinetic, safety and efficacy profiles, especially among vulnerable patients including the elderly, those with renal dysfunction or previous TEE. Yet, regarding specific settings of AF patients it is unclear whether oral anticoagulation therapy is beneficial, or otherwise it is the maintenance of sinus rhythm, mostly achieved through a catheter ablation-based rhythm control strategy, that prevents the causal complications linked to AF. While it is known that low-risk patients [CHA2DS2-VASc 0 (males), or score of 1 (females)] present low ischemic stroke or mortality rates (<1%/year), it remains unclear whether they need any prophylaxis. Furthermore, the appropriate anticoagulation regimen for those individuals requiring cardioversion, either pharmacologic or electric, as well as peri-procedural anticoagulation in patients undergoing trans-catheter ablation that nowadays encompasses different energies, are still a matter of debate. In addition, AF concomitant with other clinical conditions is discussed and, lastly, the choice of prescribing anticoagulation to asymptomatic patients diagnosed with subclinical AF at either wearable or implanted devices. The aim of this review will be to provide an update on current strategies in the above-mentioned settings, and to suggest possible therapeutic options, finally focusing on AF-related cognitive decline.

Published: May 2023

Exercise has undisputable benefits and is an important therapy component for most cardiovascular diseases, with a proven role in reducing mortality. On the contrary, exercise may paradoxically trigger sudden cardiac arrest in patients with cardiomyopathies requiring refrain from competitive sports participation. The 2020 European guidelines for patients with cardiovascular disease provided indication for sports participation for patients with cardiac conditions, including cardiomyopathies. Although in some cases, the knowledge of the natural history of the disease and the risk of death during intensive exercise is more robust, in others, the evidence is scarce. Therefore, recommendations are not available for all possible scenarios with several uncertainties. In addition, many patients aspire to continue competitive sports or practise recreational activities after a diagnosis of cardiomyopathy. These aspects generate concern for the physician, who should make complex decisions, and confronts the request to design specific exercise programmes without specific indications. This article will review the available evidence on the sports-related risk of sudden cardiac death or cardiovascular events and the progression of the disease in cardiomyopathies.
APVNFC: Adaptive Placement of Virtual Network Function Chains
Authors: Umrao Brajesh Kumar , Yadav Dharmendar Kumar
Published: May 2023

Designing efficient and flexible approaches for placement of Virtual Network Function (VNF) chains is the main success of Network Function Virtualization (NFV). However, most current work considers the constant bandwidth and flow processing requirements while deploying the VNFs in the network. The constant (immutable) flow processing and bandwidth requirements become critical limitations in an NFV-enabled network with highly dynamic traffic flow. Therefore, bandwidth requirements and available resources of the Point-of-Presence (PoP) in the network change constantly. We present an adaptive model for placing VNF chains to overcome this limitation. At the same time, the proposed model minimizes the number of changes (i.e., re-allocation of VNFs) in the network. The experimental evaluation shows that the adaptive model can deliver stable network services. Moreover, it reduces the significant number of changes in the network and ensures flow performance.
Optimized Parameter Tuning in a Recurrent Learning Process for Shoplifting Activity Classification
Authors: Ansari Mohd Aquib , Singh Dushyant Kumar
Published: May 2023

From recent past, shoplifting has become a serious concern for business in both small/big shops and stores. It customarily involves the buyer concealing store items inside clothes/bags and then leaving the store without payment. Unfortunately, no cost-effective solution is available to overcome this problem. We, therefore intend to build an expert monitoring system to automatically recognize shoplifting events in megastores/shops by recognizing object-stealing actions of humans. The method proposed utilizes a deep convolutional-based InceptionV3 architecture to mine the prominent features from video clips. These features are used to custom Long Short Term Memory (LSTM) network to discriminate human stealing actions in video sequences. Optimizing recurrent learning classifier using different modeling parameters such as sequence length and batch size is a genuine contribution of this work. The experiments demonstrate that the system proposed has achieved an accuracy of 89.36% on the synthesized dataset, which comparatively outperforms other existing methods.

Published: May 2023

Vibro-compaction is a recent technique for treating soils in the mass, thus improving its mediocre geo mechanical properties. In addition, this treatment makes it possible to minimize the risk of liquefaction, it is closely linked to the grain size of the soil to be treated. The soil underlying the construction project of the port of Nador in Morocco requires treatment to improve its characteristics and in particular to minimize the risk of liquefaction, given that Morocco is in a collision zone, near the border between the two African-Eurasian plates that are seismically active (earthquake in the city of Al Hoceima in 2004 in Morocco). The purpose of this work is to test the different parameters of vibro-compaction (mesh, vibration frequency, height of passes, duration of compaction) necessary to obtain the objectives set for the work (relative density ≥ 77 %), through the carrying out of an embarkation test on the substitute sands of the main breakwater of this Port. The in situ control tests (CPT) of the main dam, which were carried out by the substitution sand, made it possible to confirm the results of the test bench. These results stipulate on the one hand that the vibro-compaction mesh of 4.00 m is the most optimal and on the other hand that the relative density is an important parameter of liquefaction control.

Published: May 2023

Objective. Chronic kidney disease (CKD), metabolic syndrome (MetS) and insulin resistance (IR) are the major health problems associated with the increasing risk of cardiovascular and cerebrovascular complications.

Methods. This cross-sectional study included 209 CKD patients of stage (3–5) on conservative treatment to assess the usage of lipid accumulation product (LAP) and visceral adiposity index (VAI) to predict both MetS and IR in CKD patients.

Results. In males, from the anthropometric measurements, LAP was the best predictor of MetS with 94.4% sensitivity and 77.8% specificity. VAI was the next one with 83.3% sensitivity and 69.4% specificity. The same results were obtained in females. The receiver operating characteristic (ROC) curve showed LAP as the best predictor of MetS with the highest 92.6% sensitivity and 60.6% specificity followed by VAI with 83.6% sensitivity and 83.6% specificity. In addition, LAP was a good predictor of IR with more than 70% sensitivity in both males and females. VAI as a predictor of IR showed 62.2% sensitivity in males and 69.9% in females.

Conclusion. The present data indicate that both LAP and VAI can serve as predictors of MetS and IR in CKD patients, whereas LAP is the best anthropometric measure to predict MetS and LAP is more sensitive and specific than VAI in IR predicting in both males and females.

The problem of registering underground cavities and caves is an older one at national level. With the advent of several legislative initiatives regarding this type of entity, the term cadastre of caves also appeared. The case study is represented by the "Şuticoasa" Cave, which is located in the perimeter of the archaeological site, the Şinteu Fortress "Piatra Şoimului", being an integral part of the medieval monument in pestis village, a village belonging to Alesd city in Bihor county. For this purpose, this paper presents the techniques of data acquisition, their processing and a first attempt to refer to this type of entity in an existing land register.
Recent Examination of Energy Markets Volatility
Authors: Jude Octavian , Turgeman Avraham , Boţoc Claudiu
Published: May 2023

The main aim of the paper is to examine if the energy market (crude oil, gas and electricity) realized volatility exhibits a symmetric or an asymmetric behaviour, for certain commodities over the period May 2012 – August 2022. We considered this time frame for data collection because it is ensuing after the extensively researched period of the financial crises that started in 2007. We took into consideration the STOXX Europe 600 index representing large, mid and small capitalization companies across 17 countries from the European Union. Subsidiary we want to examine if there are similarities in term of realized volatility between energy markets and equity markets. For energy markets the results are consistent with the leverage hypothesis of the asymmetric volatility, i.e. negative and positive returns with the same magnitude have different impact on volatility. Furthermore the volatility is more sensitive to its lagged values in the market place than it is to new information. In addition, for the entire period volatility is asymmetric for both energy and equity markets, but there are different sub-periods with different results. These results reinforce the diversification principle that must be considered in portfolio and risk management process.
Digital Transition and Readjustment on EU Tourism Industry
Authors: Sánchez-Bayón Antonio
Published: May 2023

This is a heterodox review of Political Economy, Macroeconomics and Business Management on the readjustment effect in the tourism sector due to the impact of the digital transition and its aggravation with the COVID-19 crisis and the Ukraine war. A synthesis of the paradigmatic change with the digital economy and how it affects labor and professional relations is proposed, requiring a transformation of the economic system and the production process. Attention is focused on the tourism sector and its paradox in the European Union: despite its growing importance, however, its recognition and transformation is insufficient. This paradox is intensified in the Spanish case, where more European recovery funds are being allocated and yet the vulnerability of its SMEs and tourism entrepreneurs is growing.

Published: May 2023

In this study, phenol was adsorbed by commercial coconut shell charcoal (CSC), which is inexpensive, commercially available, non-toxic, and environmentally friendly. The measurements, namely the density functional theory (DFT) calculation, the energy-dispersive X-ray spectroscopy (EDS), and the Fourier-transform infrared spectroscopy (FTIR), were conducted to characterize the features of the CSC. The highest phenol removal efficiency reached 78.62% at optimal conditions (pH: 7, initial concentration of phenol: 20 mg/L, adsorption time: 120 minutes, and dosage of CSC: 2.5 g/L). The phenol adsorption process follows the Langmuir adsorption model with the coefficient R2 = 0.9964. The maximum adsorption capacity by the CSC was determined to be 14.32 mg/g. The process of desorption of phenol from CSC was most effective in the NaOH solution. On the other hand, the adsorption efficiency of CSC gradually decreased after five consecutive cycles. At the fifth use, the phenol uptake efficiency reached 22.2%.

Esomeprazol magnesium trihidrat merupakan obat golongan proton pump inhibitor (PPI) yang dapat digunakan dalam pengobatan tukak lambung dengan menghambat sekresi asam lambung. Namun esomeprazol dikategorikan ke dalam BCS kelas 2 dengan kelarutan yang buruk dalam air sehingga dapat berdampak pada kemampuan disolusi dan bioavailabilitasnya. SNEDDS umum digunakan untuk meningkatkan kelarutan obat lipoflilik dimana SNEDDS merupakan campuran zat aktif, minyak, surfaktan, dan ko-surfaktan yang akan membentuk nanoemulsi minyak dalam air secara spontan ketika kontak dengan fase cair dengan agitasi yang ringan. Tujuan dari penelitian ini yaitu untuk mengetahui formula SNEDDS esomeprazol magnesium trihidrat yang paling baik serta mengetahui karakteristiknya. SNEDDS diformulasikan menggunakan fase minyak berupa VCO, surfaktan berupa tween 80, dan ko-surfaktan berupa PEG 400. Sediaan SNEDDS dilakukan evaluasi berupa persen transmitan, dispersibilitas, robustness, stabilitas termodinamika, indeks bias, ukuran globul, PDI, zeta potensial, dan uji disolusi. Hasil menunjukkan bahwa SNEDDS esomeprazol magnesium trihidrat dengan rasio minyak:Smix 1:6 dan perbandingan Smix 2:1 mampu membentuk nanoemulsi secara spontan dan stabil berdasarkan uji stabilitas termodinamika, dihasilkan rata-rata ukuran globul 78,03 nm, nilai PDI 0,667, nilai zeta potensial -14,57 mV, dan dapat meningkatkan kecepatan disolusi yang lebih baik dibandingkan bentuk murninya.

Actinomycetes merupakan bakteri Gram positif, berbentuk batang panjang, dan dapat dimanfaatkan sebagai antimikroba karena dapat memproduksi senyawa metabolit sekunder. Faktor yang mempengaruhi produksi senyawa tersebut adalah waktu fermentasi dan pH. Salmonella typhi merupakan bakteri patogen yang menimbulkan penyakit demam tifoid. Penelitian ini bertujuan untuk mengetahui lama optimasi fermentasi isolat Actinomycetes dengan kontrol pH terhadap pertumbuhan bakteri S. typhi secara In Vitro. Jenis dan desain penelitian yang digunakan adalah studi true experimental dan Rancangan Acak Lengkap (RAL). Media Starch Casein Agar (SCA) digunakan untuk membiakkan Isolat Actinomycetes lalu melakukan fermentasi pada media yang mengandung mannitol 2%, pepton 2%, dan glukosa 1% serta diinkubasi selama 1, 2 dan 3 hari. Metode uji aktivitas antimikroba menggunakan metode sumuran pada media Nutrient Agar (NA). Bakteri Actinomycetes dengan lama fermentasi 1, 2 dan 3 hari disertai dengan kontrol pH mampu menghambat pertumbuhan bakteri S.typhi dengan rata-rata zona hambat yang terbentuk yaitu 13,70 mm; 15,41 mm dan 15,09 mm. Uji Kruskal Wallis menunjukkan adanya perbedaan yang bermakna terhadap zona hambat pada tiap kelompok perlakuan. Kelompok fermentasi hari ke-2 memiliki efektivitas antimikroba terbesar dengan nilai rata-rata zona hambat sebesar 15,41 mm. Mekanisme aktivitas antimikroba meliputi menghambat sintesis protein, menghambat dinding sel maupun menghambat sintesis DNA bakteri. Kata kunci: Actinomycetes; antimikroba; kontrol pH; lama fermentasi; Salmonella typhi
Combined pulmonary fibrosis and emphysema: A new horizon of smoker’s lung disease with obstructive and restrictive lung functions!
Authors: Patil Shital , Toshniwal Sham
Published: May 2023

Combined pulmonary fibrosis and emphysema (CPFE) is underestimated chronic lung disease presenting with a combo of emphysema plus interstitial lung disease. CPFE is a heterogeneous lung disease documented usually in smokers which includes emphysema in the upper lobes and pulmonary fibrosis in the lower lobes. Although CPFE is commonly called as Smoker’s lung disease , a proportionate number of cases are having concurrent connective tissue disease. High-Resolution Computed Tomography (HRCT thorax) is a gold standard investigation to evaluate CPFE due less reliability of conventional chest radiography. Pulmonary hypertension and lung cancer are two comorbidities associated with poor outcome in CPFE. Echocardiography, diffusion coefficient, and body plethysmography have documented a role in composite assessment of CPFE. Combination of bronchodilators, oxygen supplementation during rest and ambulation in selected cases and antifibrotics is having a “game changer” role in the management of CPFE.
