Knee osteoarthritis (KOA) is the most expected diagnosis for an arthropathy that causes discomfort and disability in older adults. Radiography is frequently used to assess patients with KOA and there have been few prior research evaluating the diagnostic efficacy of ultrasonography (US). The current study sought to assess the diagnostic efficacy of the US in identifying various characteristics of KOA in the scientific literature. ⋯ This study as the first systematic review aims to evaluate the diagnostic performance of US in detecting KOA. These findings shed light on the importance of investigating the different US features in the evaluation of KOA to reach appropriate sensitivity and specificity in the diagnosis.

Protein-1 (PD-1) and programmed cell death 1 ligand 1 (PD-L1) therapy have become an important treatment approach for patients with advanced nonsmall cell lung cancer (NSCLC), but primary or secondary resistance remains a challenge for some patients. PD-1/PD-L1 combined with anti-angiogenic drugs (AAs) in NSCLC patients have potential synergistic effects, and the survival benefit may vary based on a treatment order. To investigate the efficacy of PD-1/PD-L1 combined with AAs as the treatment for patients with advanced NSCLC. ⋯ The combination of PD-1/PD-L1 inhibitors with AAs in treating advanced patients has exhibited notable therapeutic advantages when contrasted with monotherapy. Specifically, the administration of PD-1/PD-L1 inhibitors in conjunction with AAs, or sequential treatment involving PD-1/PD-L1 followed by AAs, has shown enhanced therapeutic efficacy in this patient population.

The incidence of colorectal cancer (CRC) is rising in Iran, but reports vary across different regions due to diverse methods and data sources. This study aimed to conduct a systematic review and meta analysis to provide an overview of the incidence rate of CRC and its trend among Iranians in various provinces. ⋯ The incidence of CRC in Iran is lower than the global average. However, inconsistent cancer registration policies and gaps in registration have hindered the ability to establish a reliable trend of CRC incidence over time.

Both diabetes and peripheral arterial disease (PAD) have complex interactions with COVID-19. PAD is one of the most important underlying factors in the development of diabetic foot. ⋯ Since both COVID-19 and diabetes mellitus predispose to thrombosis, PAD is likely to have a more severe course in diabetic patients with COVID-19. The aim of our study is to discuss the complications, prophylaxis, and treatment of PAD, which is a serious complication of diabetes, during the pandemic period.

Oxidative stress plays a key role in brain damage because of the sensitivity of brain tissue to oxidative damage. Biomarkers with easy measurement can be a candidate for reflecting the oxidative stress issue in humans. For this reason, we need to focus on specific metabolic products of the brain. ⋯ Furthermore, because of the diffusion into the bloodstream, these lipophilic molecules can be detected in the blood. Accumulations of these compounds produce more reactive oxygen species and increase the sensitivity of cells to oxidative damage. Hence, LFPs can be considered a danger signal for neurons and can be introduced as a strong index of oxidative damage both in the central and in the peripheral.
