In this study, we discuss the existence of positive periodic solutions of a class of discrete density-dependent mortal Nicholson's dual system with harvesting terms. By means of the continuation coincidence degree theorem, a set of sufficient conditions, which ensure that there exists at least one positive periodic solution, are established. A numerical example with graphical simulation of the model is provided to examine the validity of the main results.

Background: The management of chronic leg ulcers, including venous leg ulcers (VLUs), causes a considerable economic and clinical burden to healthcare systems. Factors such as nursing time, hospital care, and wound dressings account for approximately 85% of the total cost. Superabsorbent dressings (eg, superabsorbent polymers [SAPs]) are recommended as a first-line treatment for moderately to highly exuding VLUs.

Objective/goals: Cognitive decline is intricately linked to various factors such as obesity, stress, poor sleep, and circadian rhythm misalignment, which are interrelated in their impact on cognitive health. Irregular food-intake timing further compounds these issues. The practice of prolonged nightly fasting (PNF) may help synchronize food intake with circadian rhythms, potentially mitigating adverse effects of cognitive decline and associated factors.

Background: Lidocaine in del Nido cardioplegia solution prolongs the refractory period of cardiomyocytes, yielding a longer arrest per dose. Serum lidocaine concentrations >8 mg/L are associated with seizure and cardiotoxicity. We evaluated serum lidocaine concentrations in patients receiving del Nido solution during cardiac surgery.

Background: Quantitative methods for estimating the workload of primary healthcare (PHC) workers are essential for improving the performance of PHC institutions. However, measuring the workload of PHC workers is challenging due to the diverse and complex range of services covered by PHC. This study aims to use an equivalent value (EV)-based approach to assess the workload of PHC workers and inform policymakers about the current workload burden in Beijing, China.

Background: Ankle sprains often result in muscle atrophy and reduced range of motion, which can cause long-term ankle instabilities. Understanding the changes to muscle-such as atrophy-and concomitant changes to deep fascia-which may thicken alongside muscle loss-after ankle sprain injury is important to understanding structural changes about the joint and how they might contribute to longer-term impairments. Here, we employ advanced MRI to investigate skeletal muscle and fascial structural changes during the recovery period of one patient undergoing immobilization after ankle sprains.
