Mixed pain, defined by the concurrent involvement of nociceptive, neuropathic, and sometimes nociplastic mechanisms, poses a significant diagnostic and therapeutic challenge within modern pain medicine. This complex pain phenotype is increasingly recognized as a prevalent and burdensome clinical entity, yet it remains substantially underdiagnosed and sub-optimally managed across diverse healthcare settings. Epidemiological data indicate that mixed pain affects a substantial proportion of patients with chronic pain syndromes and is consistently associated with more severe symptomatology, prolonged pain duration, functional impairment, diminished quality of life, and escalated healthcare resource utilization compared to pain of a single mechanism. In response to this unmet clinical need, the present recommendations aim to provide a structured, evidence-informed framework for the diagnosis and management of mixed pain. Developed through a rigorous process involving systematic literature review and multidisciplinary expert consensus, this document emphasizes the importance of mechanism-based therapeutic strategies tailored to the individual patient’s pain profile. Central to the approach is the implementation of multimodal and interdisciplinary care models that address the biological, psychological, and functional dimensions of mixed pain. These recommendations are intended for a broad spectrum of healthcare professionals, including primary care physicians, pain specialists, neurologists, oncologists, physiatrists, nurses, pharmacists, physical and occupational therapists, and clinical psychologists. The target population encompasses patients affected by mixed pain conditions such as chronic low back pain with radiculopathy, cancer-related pain, persistent post-surgical pain, and osteoarthritis complicated by central sensitization. By facilitating accurate diagnosis and integrated treatment planning, these recommendations seek to advance clinical practice, reduce the burden of mixed pain, and enhance patient-centered outcomes. This guidance aims to transform mixed pain care by promoting mechanism-based, multidisciplinary strategies with direct clinical applicability.
A numerical investigation has been performed to study the effect of eccentricity on unsteady state, laminar aiding mixed convection in a horizontal concentric and eccentric cylindrical annulus. The outer cylinder was kept at a constant temperature
while the inner cylinder was heated with constant heat flux. The study involved numerical solution of transient momentum (Navier-Stokes) and energy equation using finite difference method (FDM), where the body fitted coordinate system (BFC) was
used to generate the grid mesh for computational plane. The governing equations were transformed to the vorticity-stream function formula as for momentum equations and to the temperature and stream function for energy equation.

Two-dimensional unsteady mixed convection in a porous cavity with heated bottom wall is numerically studied in the present paper. The forced flow conditions are imposed by providing a hydrostatic pressure head at the inlet port that is located at the bottom of one of the vertical side walls and an open vent at the top of the other vertical side wall. The Darcy model is adopted to model the fluid flow in the porous medium and the combination effects of hydrostatic pressure head and the heat flux quantity parameters are carefully investigated. These governing parameters are varied over wide ranges and their effect on the heat transfer characteristics is studied in detail. It is found that the time required to reach a desired temperature at th

Show MoreHeat transfer applications usually contemplated day‐to‐day are primarily spotlighted on mixed convection, such as solar collector heating arrangements, electronic cooling, and drying processes. Enhancing convection heat transmission in such appliances can be achieved by inserting porous media, inflow loci, and/or line geometry. In the present paper, convection heat transmission inside a vented curved cavity () with an inserted metal foam layer ( PPI and 0.9% porosity) saturated with water was accomplished. The bottom cavity wall was discretely heated at a constant hot temperature, and the curved wall was kept at a constant cold temperature. Governing equations comprising cont
