Pulmonary hypertension (PH) is a chronic progressive disease characterized by elevated pulmonary arterial pressure, caused by an increase in pulmonary arterial impedance. Computational fluid dynamics (CFD) can be used to identify metrics representative of the stage of PH disease. However, experimental validation of CFD models is often not pursued due to the geometric complexity of the model or uncertainties in the reproduction of the required flow conditions. The goal of this work is to validate experimentally a CFD model of a pulmonary artery phantom using a particle image velocimetry (PIV) technique...

BACKGROUND: The management of patients in primary care is often complicated by the presence of multiple chronic conditions and psychosocial issues that increase the complexity of the encounter and have important impacts on care. There is a paucity of literature on this subject in the pediatric population. OBJECTIVES: The aim of this study was to quantify the burden of chronic conditions in pediatric primary care. METHODS: The problem lists of 3995 randomly selected patients from a community pediatric clinic and an academic hospital-based pediatric clinic in the same metropolitan area were analyzed for the presence and number of any chronic condition...

The temporomandibular joint disorder, also known as myofascial pain syndrome, is considered one of the prevalent chronic pain diseases caused by muscle inflammation and cartilage degradation in head and neck, and thus influences even biopsychosocial conditions in a lifetime. There are several current treatment methodologies relieving inflammation and preventing degradation of the joint complex. One of the promising non-surgical treatment methods is an intra-articular injection of drugs such as corticosteroids, analgesics, and anti-depressants...

REVIEW
Christina Stonoha-Arther, Dong Wang
The symbiosis formed by nitrogen-fixing bacteria with plant hosts mainly in the legume family involves a very intimate interaction. Within the symbiotic organ (the nodule) the bacteria are fully internalized by the host cell to become an intracellular organelle surrounded by a host-derived membrane. This arrangement is probably necessary for the efficient provision of energy and the sequestration of free oxygen molecules, two conditions required for sustained nitrogen fixation. Recent advances made in model legume species, such as Medicago truncatula, are beginning to uncover the genetic components allowing rhizobia to access the host cytoplasm and establish chronic intracellular infections without overt detrimental effects...

BACKGROUND: Pain is a complex and subjective reality and can be magnified by nonorganic or nonanatomic sources. Multiple studies have demonstrated a correlation between psychological factors and patients' perceptions of musculoskeletal pain and disability. In addition, nonorganic findings as part of the physical examination are well and long recognized. The purpose of this study was to analyze the relationship between a shoulder examination test, palpation of the sternoclavicular joint (SCJ), and psychosocial conditions including chronic pain, depression, and anxiety...

PURPOSE: Chronic pain is a complex and debilitating chronic health condition that negatively impacts a child's daily function. Previous investigations of coping behaviors in youth with chronic illness have suggested that secondary control/accommodative coping may be more adaptive than primary control/active coping or disengagement/passive coping. However, studies have not considered how pain intensity may change the effect of various coping strategies on functioning in this pediatric population...

Background: Evidence is overwhelming for sex differences in pain, with women representing the majority of the chronic pain patient population. There is a need to explore novel avenues to elucidate this sex bias in the development of chronic inflammatory pain conditions. Complex regional pain syndrome (CRPS) is a chronic neuropathic pain disorder, and the incidence of CRPS is greater in women than in men by ~4:1. Since neurogenic inflammation is a key feature of CRPS, dysregulation of inflammatory responses can be a factor in predisposing women to chronic pain...

With decreasing kidney function, cardiovascular disease (CVD) and mineral bone disorders frequently emerge in patients with chronic kidney disease (CKD). For these patients, in addition to the traditional risk factors, non-traditional CKD-specific risk factors are also associated with such diseases and conditions. One of these non-traditional risk factors is the accumulation of uremic toxins (UTs). In addition, the accumulation of UTs further deteriorates kidney function. Recently, a huge number of UTs have been identified...

Recently, national attention has focused on the needs of family caregivers providing complex chronic care, noting the necessity to better understand the scope of challenges they encounter. Although a robust body of literature exists about the scope of family caregiving, little is known specifically about the experiences and perspectives of family caregivers who support participant directed (PD) participants, particularly across the caregiving trajectory. Therefore, the aim of this qualitative descriptive study was to describe what family caregivers of individuals with developmental disabilities, physical disabilities, aging, or chronic health conditions identify as the challenges they experience as complex, and their perceptions of the effectiveness and gaps in family support resources in PD...

BACKGROUND: Patients with established tracheostomy and ventilator dependence are hospitalized more frequently and use more healthcare resources than other patients with complex chronic conditions. However, data to compare variation in hospitalization and resource use among patients in this population across the United States is deficient, partly due to the lack of structured methods to query national databases. AIM: Determine the best method for identifying the subset of children with established tracheostomy and ventilator dependence in Pediatric Health Information System (PHIS)...

REVIEW
Fernando Perez-Ruiz, Giovambattista Desideri
Gout is the most common form of inflammatory arthritis and is a considerable burden to patients and health care systems worldwide. Despite its clinical, economic, and social impact, patient persistence and adherence to prescribed urate-lowering therapies (ULT), ranging from 20% to 70%, is considered to be among the poorest of all chronic conditions. The majority of gout patients consequently receive suboptimal benefits of their prescribed pharmacotherapies. As gout is associated with several comorbidities along with an increased risk of premature mortality, achieving improved outcomes through adherence to ULT is crucial...

Dendritic cells (DCs) are the most potent and specialized antigen-presenting cells (APCs) currently known, which play a crucial role in initiating and amplifying both the innate and adaptive immune responses. During the process of immune function, migration ability of DCs and the number of effector T cells which activated by DCs are closely related to the efficiency of immune function. However, because of the complexity of immune system, in the immune response process caused by the skin chronic inflammatory, much is still unknown about the dynamic changes of cell count with time...

The postoperative care of animals implanted with mechanical circulatory support devices is complex. The standard of care requires continuous monitoring of hemodynamic parameters post implant, wound care, and maintenance of the animal's well-being, but also includes controlling the animal's biomechanics under conditions of continuous restraint and harnessing. In such studies, a harness provides secure fixation of the exteriorized device driveline and pressure lines and aids animal handling (lifting, position adjustment, and assistance with standing up)...

Sex steroidal hormones coordinate the development and maintenance of tissue architecture in many organs, including the central nervous systems (CNS). Within the CNS, sex steroids regulate the morphology, physiology, and behavior of a wide variety of neural cells including, but not limited to, neurons, glia, endothelial cells, and immune cells. Sex steroids spatially and temporally control distinct molecular networks, that, in turn modulate neural activity, synaptic plasticity, growth factor expression and function, nutrient exchange, cellular proliferation, and apoptosis...
