One-pot MCDA-CRISPR-Cas-based detection platform for point-of-care testing of severe acute respiratory syndrome coronavirus 2.

Compared to quantitative real-time PCR (q-PCR), CRISPR-Cas-mediated technology is more suitable for point-of-care testing (POCT) and has potential for wider application in the future. Generally, the operational procedure of CRISPR-Cas-mediated diagnostic method consists of two independent steps, the reaction of signal amplification and the CRISPR-Cas-mediated signal detection. Complex multi-step procedures can easily lead to cross-contamination.

Effectiveness of high-intensity inspiratory muscle training, and resistance and aerobic exercise for cardiovascular health in chronic obstructive pulmonary disease (HIRAC-COPD): a randomized controlled trial protocol.

Background: Cardiovascular diseases are among the most common and clinically significant comorbidities of chronic obstructive pulmonary disease (COPD). Exercise has been shown to reduce the risk of cardiovascular diseases, and high-intensity inspiratory muscle training (H-IMT) has emerged as a promising intervention for improving arterial stiffness in individuals with COPD. Yet, there is limited evidence from randomized controlled trials (RCTs) regarding the impact of H-IMT alone or in combination with exercise on reducing arterial stiffness in COPD.

Clinical, aetiological, and epidemiological studies of outpatient cases of hand, foot, and mouth disease in Chengdu, China, from 2019 to 2022: a retrospective study.

Background: The introduction of the Enterovirus A71 (EV-A71) vaccine in China in 2016 has led to a considerable decline in severe hand, foot, and mouth disease (HFMD) cases, with mild outpatient instances now representing the majority of HFMD cases in the country. Nevertheless, epidemiological investigations concerning mild outpatient cases remain scarce, resulting in inadequate descriptions of their clinical, etiological, and epidemiological characteristics. Our study aimed to analyze the clinical, etiological, and epidemiological characteristics of HFMD outpatients in Chengdu from 2019 to 2022 while identifying potential risk factors associated with the progression of outpatients requiring hospitalization.

Hydroalkylation of unactivated olefins with C(sp)─H compounds enabled by NiH-catalyzed radical relay.

The hydroalkylation reaction of olefins with alkanes is a highly desirable synthetic transformation toward the construction of C(sp)─C(sp) bonds. However, such transformation has proven to be challenging for unactivated olefins, particularly when the substrates lack directing groups or acidic C(sp)─H bonds. Here, we address this challenge by merging NiH-catalyzed radical relay strategy with a HAT (hydrogen atom transfer) process.

Factors Associated with Potentially Preventable Hospitalizations for COPD Patients: A Qualitative Analysis of Patient Perspectives.

Purpose: Ambulatory Care Sensitive Conditions (ACSCs) refer to hospital encounters that could potentially be prevented with improved primary care. Chronic Obstructive Pulmonary Disease (COPD) as one of the typical ACSCs, and its hospitalization is considered potentially preventable through the quality primary care. However, the literature on factors influencing Potentially Preventable Hospitalization (PPH) has rarely been conducted from the patient perspective, especially in China.

Method: Retrieved from PubMed, Embase, and the Cochrane Library, all relevant studies about PD-1 inhibitors for neoadjuvant treatment of LACRC were collected from inception to 31 December 2023. The efficacy was assessed by the rate of pathological complete response (PCR), clinical complete response (CCR), and major pathological response (MPR), and the safety was evaluated by the incidence of all adverse effects (TRAEs).

Coexistence of tubulocystic renal cell carcinoma and polycythemia vera: A rare case report.

Tubulocystic Renal Cell Carcinoma (TC-RCC) and Polycythemia Vera (PV) are both infrequent medical conditions. TC-RCC was recognized as a distinct subtype of kidney cancer by the World Health Organization in 2016, while PV is a rare myeloproliferative neoplasm distinguished by the excessive production of red blood cells. The coexistence of these two conditions is exceptionally uncommon and lacks comprehensive documentation.
