Background: On March 11, 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. During the virus's spread and subsequent lockdowns, older adults faced heightened risks and significant mental health challenges.

Methods: A cross-sectional study was conducted in Shandong Province, China, using a custom-designed demographic questionnaire, a COVID-19-related survey, and the Symptom Checklist-90 Revised (SCL-90-R).

Biomimetic Dehydrogenative Intermolecular Formal Allylic Amidation of Branched α-Olefins.

Allylic amide moieties are commonly encountered in natural products and are privileged structures in pharmaceuticals and agrochemicals. Moreover, because allylic amide can be to converted into an array of high-value motifs, they have been widely employed in organic synthesis. However, the development of catalytic systems for intermolecular allylic amidation of olefins, particularly branched α-olefins, has proven to be challenging.

Triglyceride-lowering therapies in hypertriglyceridemia-associated acute pancreatitis in China: a multicentre prospective cohort study.

Background: No specific triglyceride-lowering therapy is recommended in patients with hypertriglyceridemia-associated acute pancreatitis (HTG-AP), primarily because of the lack of quality evidence. This study aimed to describe practice variations in triglyceride-lowering therapies for early HTG-AP patients and assess whether more rapid triglyceride decline is associated with improving organ failure.

Methods: This is a multicentre, prospective cohort study recruiting HTG-AP patients with elevated plasma triglyceride (> 11.

Silver-catalyzed cascade cyclization for the synthesis of 4-aminotetrahydrocarbazole.

A silver-catalyzed cascade cyclization strategy has been developed for the synthesis of 4-aminotetrahydrocarbazole, a common core structure found in various alkaloids. This target molecule can be synthesized through a one-step tandem cyclization reaction, thereby eliminating the need for a prior synthesis of tetrahydrocarbazole. Furthermore, the use of chiral -butylsulfinamide facilitates chiral resolution of the resulting product.

Methods: Translation and cross-cultural adaptation using the Brislin translation model, and pre-testing to form a Chinese version of TSEDS. A total of 434 adults participated in the study and the TSEDS were measured using the critical ratio method, Pearson correlation analysis, retest reliability, content validity, structural validity, and concurrent validity.

The association between occupational stress, sleep quality and premenstrual syndrome among clinical nurses.

Objective: Premenstrual Syndrome is also known as premenstrual tension syndrome because of the pronounced premenstrual mental and emotional anomalies. This study focuses on the association between occupational stress, sleep quality and premenstrual syndrome in clinical nurses and the mediating role of sleep quality.

Methods: A cross-sectional study was conducted to measure occupational stress, sleep quality and premenstrual syndrome in 415 clinical nurses using the Chinese Nurses Stressor Scale, the Pittsburgh Sleep Quality Index Scale, and the Premenstrual Syndrome Scale.

Design, Synthesis, and Acaricidal Activity of 2,5-Diphenyl-1,3-oxazoline Compounds.

By using a scaffold hopping/ring equivalent and intermediate derivatization strategies, a series of compounds of 2,5-diphenyl-1,3-oxazoline with substituent changes at the 5-phenyl position were prepared, and their acaricidal activity was studied. However, the synthesized 2,5-diphenyl-1,3-oxazolines showed lower activity against mite eggs and larvae compared to the 2,4-diphenyl-1,3-oxazolines with the same substituents. We speculate that there is a significant difference in the spatial extension direction of the substituents between the two skeletons of compounds, resulting in differences in their ability to bind to the potential target chitin synthase 1.

The impact of protein delivery on short-term and long-term clinical outcomes in critically ill patients: Protocol for a multicenter, prospective, observational study (The ACTION study).

Background And Aims: Nutrition therapy is a vital part of the management of critically ill patients. Efforts have been made to optimize nutrition therapy in the ICU setting, and it is argued that protein might be the most important substrate to deliver during critical illness. However, the impact of protein delivery on patient-centered outcomes, including short-term and long-term outcomes, is controversial.

Iron-Catalyzed Electrophotochemical α-Functionalization of a Silylcyclobutanol.

Four-membered ring structure is important in organic chemistry, and selective cleavage and functionalization of these strained rings are of great interest. However, direct α-functionalization of cyclobutanols is rarely reported because of the high O-H bond dissociation energy and the occurrence of β-scission of C-C bonds in these alcohols. Recently, transition-metal catalysis has facilitated alkoxy radical generation.

Deboronative functionalization of alkylboron species a radical-transfer strategy.

With advances in organoboron chemistry, boron-centered functional groups have become increasingly attractive. In particular, alkylboron species are highly versatile reagents for organic synthesis, but the direct generation of alkyl radicals from commonly used, bench-stable boron species has not been thoroughly investigated. Herein, we describe a method for activating C-B bonds by nitrogen- or oxygen-radical transfer that is applicable to alkylboronic acids and esters and can be used for both Michael addition reactions and Minisci reactions to generate alkyl or arylated products.

Palladium-Catalyzed Coordination-Induced Remote C-H Aryl Etherification/Amination of 8-Amidoquinolines.

Herein, we report a direct method for palladium-catalyzed coordination-induced oxidative remote C-H aryl etherification of 8-amidoquinolines with -benzoquinone monoacetal. The method provides access to C5-aryl etherified quinolines and shows site-selectivity different from that of typical palladium-catalyzed C(sp)-H activation reactions. The -benzoquinone monoacetals act both as oxidants and as aryl etherification reagents.

Early protein delivery in critically ill patients with acute kidney injury: analysis of a multicenter cluster-randomized controlled trial.

Background: There is controversy over the optimal early protein delivery in critically ill patients with acute kidney injury (AKI). This study aims to evaluate whether the association between early protein delivery and 28-day mortality was impacted by the presence of AKI in critically ill patients.

Methods: This is a analysis of data from a multicenter cluster-randomised controlled trial enrolling newly admitted critically ill patients (n = 2772).

Psychometric evaluation of the Chinese version of the febrile convulsion knowledge scale for parents/caregivers: translation and validation study.

Background: Fever is one of the most common clinical symptoms of respiratory diseases in children. Once the child has a fever, parents and caregivers are mainly concerned that the child may have a febrile convulsion. A lack of cognitive ability not only leads to anxiety but also aggravates or delays the time of children's medical treatment and even seriously affects the prognosis because of improper management of fever patients.

Homologous Design and Three-Dimensional Quantitative Structure-Activity Relationship Study of Acaricidal 2,4-Diphenyloxazolines Containing Different Heteroatoms and Alkyl Chains.

In order to speculate the three-dimensional structure of the potential binding pocket of the chitin synthase inhibitor, a series of 2,4-diphenyloxazoline derivatives with different lengths of alkyl chains and heteroatoms were designed and synthesized by a homologous strategy. The bioassay results indicate that both the length of the alkyl chains and the type of substituents can affect the acaricidal activity against mite eggs. Compounds containing chloropropyl, alkoxyalkyl, and para-substituted phenoxyalkyl or phenylthioalkyl groups exhibit good activity, while those containing steric hindrance substituents or carbonyl substituents on the benzene ring exhibit reduced activity.

Biomechanical changes in the proximal femur before and after removal of femoral neck system.

Background: As an innovative internal fixation system, FNS (femoral neck system) is increasingly being utilized by surgeons for the treatment of femoral neck fractures. At present, there have been numerous finite element analysis experiments studying the immediate stability of FNS and CSS in treating femoral neck fractures. However, there is scarce mechanical analysis available regarding the effects post internal fixation removal.

Balanced Solution Versus Normal Saline in Predicted Severe Acute Pancreatitis: A Stepped Wedge Cluster Randomized Trial.

Objective: To compare the effect of balanced multielectrolyte solutions (BMESs) versus normal saline (NS) for intravenous fluid on chloride levels and clinical outcomes in patients with predicted severe acute pancreatitis (pSAP).

Background: Isotonic crystalloids are recommended for initial fluid therapy in acute pancreatitis, but whether the use of BMES in preference to NS confers clinical benefits is unknown.

Methods: In this multicenter, stepped-wedge, cluster-randomized trial, we enrolled patients with pSAP (acute physiology and chronic health evaluation II score ≥8 and C-reactive protein >150 mg/L) admitted within 72 hours of the advent of symptoms.

Adipose Triglyceride Lipase-Mediated Adipocyte Lipolysis Exacerbates Acute Pancreatitis Severity in Mouse Models and Patients.

Dyslipolysis of adipocytes plays a critical role in various diseases. Adipose triglyceride lipase (ATGL) is a rate-limiting enzyme in adipocyte autonomous lipolysis. However, the degree of adipocyte lipolysis related to the prognoses in acute pancreatitis (AP) and the role of ATGL-mediated lipolysis in the pathogenesis of AP remain elusive.
