Abstract: Chronic pain is a primary health problem in people living with HIV (PWH). However, there is limited research regarding chronic pain among PWH in Chinese health care settings. To investigate biopsychosocial factors of chronic pain severity, we conducted a cross-sectional study in Shenzhen, China. Chronic pain was defined as pain lasting for more than three months. Pain intensity was measured using the numeric rating scale (NRS). Among 123 hospitalized PWH, 78.86% of participants had mild pain and 21.14% had moderate-severe pain. Multiple logistic regression results indicated that PWH in moderate-severe pain group were more likely to have higher levels of interleukin [IL]-6 (OR = 1.034, 95% CI: 1.003-1.066, p = .029) and anxiety (OR = 1.334, 95% CI: 1.071-1.662, p = .010) than those in the mild chronic pain group. Targeted pain management interventions should be explored in clinical practices and future studies regarding PWH with high levels of IL-6 and anxiety., (Copyright © 2023 Association of Nurses in AIDS Care.)

The Chinese Loess Plateau has been the cradle of Chinese civilization and the main human settlement in China for thousands of years, where anthropogenic activities are believed to have deeply eroded natural landscapes. After decades of minimal leopard sighting in forests of northern China, due to serious human interference, we recently discovered that the leopard population is recovering. This finding provides hope for successful biodiversity conservation in human-dominated ecosystems. To understand the mechanism of leopard return into such a highly fragmented landscape, we applied the concept of ecological networks (ENs) to identify key factors promoting leopard restoration and quantify the ecological links among habitats. We first determined the existence of a healthy leopard population in the study area based on the size of its home range and presence of breeding individuals. We then innovatively used the relationship between species richness and top predators to generate ENs, and found that the connectivity of ENs had a significant positive interaction with leopard survival. Our study validates the effectiveness of establishing ecologically connected habitats for leopard protection, and highlights the importance of applying ENs for conservation planning in highly fragmented ecosystems. This study provides a successful case for the protection of top predators in human-dominated landscapes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.
