COVID-19 is a trigger of autoimmune rheumatic diseases: a hypothesis tested over time.
Rheumatol Int

Department of General Practice N2, South Kazakhstan Medical Academy, Shymkent, Kazakhstan.
We discuss the paper recently published in Rheumatology Internationa. This article reflects on the prevalence of autoimmune rheumatic diseases (ARD) during the COVID-19 pandemic (2020-2023) and compares the same with the pre-pandemic period (2016-2019). We assume that SARS-CoV-2 triggers ARD.

A novel adaptive model-based motion control method for multi-UAV communication relay is proposed, which aims at improving the networks connectivity and the communications performance among a fleet of ground unmanned vehicles. The method addresses the challenge of relay UAVs motion control through joint consideration with unknown multi-user mobility, environmental effects on channel characteristics, unavailable angle-of-arrival data of received signals, and coordination among multiple UAVs. The method consists of two parts: (1) Network connectivity is constructed and communication performance index is defined using the minimum spanning tree in graph theory, which considers both the communication link between ground node and UAV, and the communication link between ground nodes.

To address the challenges related to active power dissipation and node voltage fluctuation in the practical transformation of power grids in the field of new energy such as wind and photovoltaic power generation, an improved Dung Beetle Optimization Algorithm Based on a Hybrid Strategy of Levy Flight and Differential Evolution (LDEDBO) is proposed. This paper systematically addresses this issue from three aspects: firstly, optimizing the DBO algorithm using Chebyshev chaotic mapping, Levy flight strategy, and differential evolution algorithm; secondly, validating the algorithm's feasibility through real-time network reconfiguration at random time points within a 24-h period; and finally, applying the LDEDBO to address the dynamic reconfiguration problems of the IEEE-33 and IEEE-69 node bus. The simulation indicates that the power dissipation of the IEEE-33 node bus is decreased by 28.

Department of Thyroid Surgery, The Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University/Hunan Cancer Hospital, Changsha, 410013, Hunan, P. R. China.
The management of papillary thyroid carcinoma (PTC) concurrent with Hashimoto's thyroiditis (HT) lacks standardized guidelines, especially concerning surgical strategies. This study aimed to compare unilateral thyroidectomy (UT) with total thyroidectomy (TT) in PTC-HT patients to optimize clinical management and improve postoperative outcomes. This retrospective study included PTC-HT patients undergoing thyroid surgery at a tertiary academic medical institution from January 2018 to August 2023.

Sci Rep
December 2024
Department of Cardiology, Hacettepe University Faculty of Medicine, Ankara, Turkey.
This study evaluated the management of dyslipidemia in Turkey with the goal of understanding current diagnosis and treatment patterns, as well as identifying unmet needs in achieving effective low-density lipoprotein cholesterol (LDL-C) targets. Using a Delphi panel consisting of nine expert cardiologists, the study reveals key gaps in dyslipidemia management, particularly in the underutilization of combination therapies, such as statins and PCSK9 inhibitors, which are crucial for achieving LDL-C targets in high-risk patients. The findings indicate that while many patients with very high cardiovascular risk are diagnosed, a significant proportion do not receive optimal treatment to reach LDL-C levels recommended by European guidelines.
