Interventional Bridging Therapy for Radical Cardiac Surgery in a Patient Seemed to be Inoperable Due to Very Poor Left Ventricular Function: A Case Report.

Cases that are inoperable owing to poor preoperative conditions are sometimes encountered. However, there are some cases that are led to radical treatment by performing bridge therapy. Here, we presented a case of a patient with complex cardiac disease in an inoperable state who underwent bridging therapy that led to successful surgical treatment. A 73-year-old male who received hemodialysis treatment and had severe aortic valve stenosis and coronary artery disease planned surgical treatment. However, he was deemed inoperable owing to his low cardiac function and hemodynamic instability. Therefore, to escape from a fatal condition, we first performed balloon aortic valvuloplasty and percutaneous coronary intervention as palliative procedures. Subsequently, his cardiac function and hemodynamic stability remarkably improved; therefore, after 1 month, we performed a successful radical surgical treatment. Even in inoperable patients, bridging therapy leading to radical treatment is possible.

Real-time object detection, tracking, and monitoring framework for security surveillance systems.

The concept of security is becoming a global challenge, and governments, stakeholders, corporate societies, and individuals must urgently create a reasonable protection mechanism for good. Therefore, a real-time surveillance system is essential for detection, tracking, and monitoring. Many studies have attempted to provide better solutions but more research and better approaches are essential. This study presents a real-time framework for object detection and tracking for security surveillance systems. The system has been designed based on approximate median filtering, component labeling, background subtraction, and deep learning approaches. The new algorithms for object detection, tracking, and recognition have been implemented using Python and integrated with C# programming languages for ease of use. A software application framework is designed, implemented, and evaluated. The experimental results based on MOT-Challenge performance metrics show that the proposed algorithms have much better performance in terms of accuracy and precision on the MOT15, MOT16, and MOT17 datasets compared to state-of-the-art approaches. This framework also provides an accurate and effective means of monitoring and recognizing moving objects. The software development, including the design of the framework user interfaces, is coded in the C# programming language and integrated with Python using Microsoft Visual Studio (2019 edition). The integration is performed to provide a convenient user interface and to enable the execution of the framework as a standard and standalone software application. Future studies will consider the dynamic scalability of the framework to accommodate different surveillance application areas in overcrowded scenarios. Multiple data sources are integrated to enhance the performance for different scene times, locations, and weather conditions. Furthermore, other object-detection techniques such as You Only Look Once (YOLO) and its variants shall be considered in future studies. These techniques allow the framework to adapt to complex situations in which security surveillance is challenging.

Compositionally Sequenced Interfacial Layers for High-Energy Li-Metal Batteries.

Electrolyte additives with multiple functions enable the interfacial engineering of Li-metal batteries (LMBs). Owing to their unique reduction behavior, additives exhibit a high potential for electrode surface modification that increases the reversibility of Li-metal anodes by enabling the development of a hierarchical solid electrolyte interphase (SEI). This study confirms that an adequately designed SEI facilitates the homogeneous supply of Li+, nonlocalized Li deposition, and low electrolyte degradation in LMBs while enduring the volume fluctuation of Li-metal anodes on cycling. An in-depth analysis of interfacial engineering mechanisms reveals that multilayered SEI structures comprising mechanically robust LiF-rich species, electron-rich P-O species, and elastic polymeric species enabled the stable charge and discharge of LMBs. The polymeric outer SEI layer in the as-fabricated multilayered SEI could accommodate the volume fluctuation of Li-metal anodes, significantly enhancing the cycling stability Li||LiNi0.8Co0.1Mn0.1O2 full cells with an electrolyte amount of 3.6 g Ah-1 and an areal capacity of 3.2 mAh cm-2. Therefore, this study confirms the ability of interfacial layers formed by electrolyte additives and fluorinated solvents to advance the performance of LMBs and can open new frontiers in the fabrication of high-performance LMBs through electrolyte-formulation engineering.

Twelve-month effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide in treatment-naïve and treatment-experienced people with HIV: Findings from the Asia cohort of the BICSTaR study.

BACKGROUND: The ongoing, observational BICSTaR (BICtegravir Single Tablet Regimen) cohort study is evaluating real-world effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with HIV across 14 countries over 24 months. We present 12-month data from the BICSTaR Asia cohort. METHODS: Data were pooled from retrospective and prospective cohorts of antiretroviral therapy (ART)-naïve (hereafter, TN) and ART-experienced (hereafter, TE) people with HIV (aged ≥21 years) receiving B/F/TAF in routine clinical care in the Republic of Korea, Singapore, and Taiwan. Analyses included effectiveness (primary endpoint: HIV-1 RNA <50 copies/ml, missing = excluded analysis), CD4 count, CD4/CD8 ratio, safety, treatment persistence, and patient-reported outcomes (prospective group). RESULTS: The analysis population included 328 participants (80 retrospective, 248 prospective; 65 TN, 263 TE). Participants were predominantly male (96.9% TN, 93.2% TE) with ≥1 comorbidity (52.3% TN, 57.8% TE); median age (years) was 31 (TN) and 42 (TE). Following 12 months of B/F/TAF, HIV-1 RNA was <50 copies/ml in 98.2% (54/55) of TN and 97.0% (227/234) of TE participants. Median (Q1, Q3) CD4 cell count increased by +187 (119, 291) cells/µl in the TN group (p < 0.001) and remained stable (+8 [-91, 110] cells/µl) in the TE group. B/F/TAF persistence was high in the prospective group, with 1/34 (2.9%) TN and 5/214 (2.3%) TE participants discontinuing treatment within 12 months. Drug-related adverse events occurred in 5.8% (19/328) of participants, leading to treatment discontinuation in 0.6% (2/328). CONCLUSIONS: Real-world evidence from BICSTaR supports the effectiveness, safety and tolerability of B/F/TAF in people with HIV in Asia.

Methylsulfonylmethane ameliorates metabolic-associated fatty liver disease by restoring autophagy flux via AMPK/mTOR/ULK1 signaling pathway.

Introduction: Metabolism-associated fatty liver disease (MAFLD) is a global health concern because of its association with obesity, insulin resistance, and other metabolic abnormalities. Methylsulfonylmethane (MSM), an organic sulfur compound found in various plants and animals, exerts antioxidant and anti-inflammatory effects. Here, we aimed to assess the anti-obesity activity and autophagy-related mechanisms of Methylsulfonylmethane. Method: Human hepatoma (HepG2) cells treated with palmitic acid (PA) were used to examine the effects of MSM on autophagic clearance. To evaluate the anti-obesity effect of MSM, male C57/BL6 mice were fed a high-fat diet (HFD; 60% calories) and administered an oral dose of MSM (200 or 400 mg/kg/day). Moreover, we investigated the AMP-activated protein kinase (AMPK)/mechanistic target of rapamycin complex 1 (mTORC1)/UNC-51-like autophagy-activating kinase 1 (ULK1) signaling pathway to further determine the underlying action mechanism of MSM. Results: Methylsulfonylmethane treatment significantly mitigated PA-induced protein aggregation in human hepatoma HepG2 cells. Additionally, Methylsulfonylmethane treatment reversed the PA-induced impairment of autophagic flux. Methylsulfonylmethane also enhanced the insulin sensitivity and significantly suppressed the HFD-induced obesity and hepatic steatosis in mice. Western blotting revealed that Methylsulfonylmethane improved ubiquitinated protein clearance in HFD-induced fatty liver. Remarkably, Methylsulfonylmethane promoted the activation of AMPK and ULK1 and inhibited mTOR activity. Conclusion: Our study suggests that MSM ameliorates hepatic steatosis by enhancing the autophagic flux via an AMPK/mTOR/ULK1-dependent signaling pathway. These findings highlight the therapeutic potential of MSM for obesity-related MAFLD treatment.
