Primary ciliary dyskinesia (PCD) is characterized by impaired mucociliary clearance, recurrent respiratory infections, progressive airway damage, and obstructive lung disease. Although the association of ciliary ultrastructure defect/genotype with the severity of airflow obstruction has been well characterized, their association with airway abnormalities on chest computed tomography (CT) has been minimally evaluated. We sought to delineate the association of ciliary defect class/genotype with chest CT scores in children with PCD.

To determine if there is an association between presence and/or type of laterality abnormality and ciliary ultrastructural defect or genotype. Participants with primary ciliary dyskinesia in a multicenter, prospective study were grouped based on ciliary ultrastructural defect or genotype.

We investigated relationships between sputum inflammation measurements, age, lung function, bronchiectasis, airway infection, and ultrastructural defects in children with PCD. Spontaneously expectorated sputum was collected from clinically stable children and adolescents with PCD ages 6 years and older participating in a multicenter, observational study.

There is wide variability in respiratory disease severity at birth and later in life. To evaluate the association between neonatal hospital length of stay (neonatal-LOS) and supplemental oxygen duration (SuppO) with lung function in pediatric PCD.
View Article and Find Full Text PDFPrimary ciliary dyskinesia (PCD) is a rare lung disease caused by mutations that impair the function of motile cilia, resulting in chronic upper and lower respiratory disease, reduced fertility, and a high prevalence of situs abnormalities. The disease is genetically and phenotypically heterogeneous, with causative mutations in > 50 genes identified, and clinical phenotypes ranging from mild to severe. Absence of (), a component of the outer dynein arm docking complex, results in a failure to assemble outer dynein arms (ODAs), mostly immotile cilia, and a typical PCD phenotype.
View Article and Find Full Text PDFBackground: Primary ciliary dyskinesia (PCD) is a genetically diverse disease which causes impaired mucociliary clearance, and results in pulmonary, otologic, and rhinologic disease in affected patients. Genetic mutations in multiple genes impair the ability of patients to clear mucous from the lungs, middle ear, and sinonasal cavity and lead to chronic pulmonary and sinonasal symptoms.
Methods: We identified 17 PCD patients who had available CT scans.
Background: The diagnosis of primary ciliary dyskinesia (PCD) is difficult and requires a combination of clinical features, nasal nitric oxide testing, cilia ultrastructural analysis by electron microscopy (EM), and genetics. A recently described cytoplasmic ultrastructural change termed "ciliary inclusions" was reported to be diagnostic of PCD; however, no supporting evidence of PCD was provided. In this study, we sought to confirm, or refute, the diagnosis of PCD in subjects with "ciliary inclusions" on EM.

Objectives: There is growing evidence of both hypothalamic-pituitary-adrenal (HPA) axis and immune system dysfunction in schizophrenia. Additionally, accumulating evidence has linked dysfunction in the kynurenine pathway to schizophrenia as well as to stress and inflammation. The current pilot tested changes in immune, cortisol and kynurenine and kynurenic acid responses to a psychosocial stressor in people with schizophrenia and healthy controls.
View Article and Find Full Text PDFRationale: In primary ciliary dyskinesia, factors leading to disease heterogeneity are poorly understood.
Objectives: To describe early lung disease progression in primary ciliary dyskinesia and identify associations between ultrastructural defects and genotypes with clinical phenotype.
Methods: This was a prospective, longitudinal (5 yr), multicenter, observational study.
Purpose/background: Prolactin-related adverse effects contribute to nonadherence and adverse health consequences, particularly in women with severe mental illness. Treating these adverse effects may improve treatment acceptability, adherence, and long-term outcomes.
Methods/procedures: Premenopausal women with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder were recruited for a randomized, double-blind, placebo-controlled 16-week trial of adjunct aripiprazole (5-15 mg/d).
People with schizophrenia are 3-4 times more likely to die from cardiovascular disease than the general population. Clozapine (CLZ) is the gold standard of treatment for refractory schizophrenia. It has been associated with tachycardia and recent evidence shows individuals prescribed CLZ may develop blood pressure (BP) elevation and hypertension.
View Article and Find Full Text PDFRationale: Primary ciliary dyskinesia (PCD), a genetically heterogeneous, recessive disorder of motile cilia, is associated with distinct clinical features. Diagnostic tests, including ultrastructural analysis of cilia, nasal nitric oxide measurements, and molecular testing for mutations in PCD genes, have inherent limitations.
Objectives: To define a statistically valid combination of systematically defined clinical features that strongly associates with PCD in children and adolescents.
Background: While clozapine (CLZ) is the most effective antipsychotic drug for schizophrenia treatment, it remains underused. In order to understand the barriers of frequent blood draws for white blood cell counts (WBCs) and clozapine levels, we developed a psychiatrist survey and began an integrative approach of designing a point-of-care device that could eventually have real-time monitoring with immediate results.
Methods: We ascertained barriers related to CLZ management and the acceptance of possible solutions by sending an anonymous survey to physicians in psychiatric practice (n=860).
Objective: Clozapine is the most effective antipsychotic for treatment refractory people with schizophrenia, yet many patients only partially respond. Accumulating preclinical and clinical data suggest benefits with minocycline. We tested adjunct minocycline to clozapine in a 10-week, double-blind, placebo-controlled trial.

Fifty-seven studies, published between 1989 and 2009, were analyzed using a sex and gender lens. Results indicate that mother's prenatal and postnatal smoking influences girls' smoking more than boys' smoking.

The purpose of this article is to report smoking relatives' responses to a family member's diagnosis of lung disease, their constructions of smoking in this context, and their interaction patterns with the patient. Interviews with 11 family members where there was a diagnosis of lung cancer and 3 family members where there was another serious smoking-related diagnosis were analyzed.

Study Selection: A search of the PubMed and Science Direct databases, limited to articles in the English language, published between January 2002 and November 2007.
Data Extraction: Employing a mixed methods approach, several categories of youths' smoking status were obtained from a literature review and subsequently reproduced by using responses to detailed questionnaire items.
Purpose/objectives: To explore the influence of lung cancer diagnosis on interpersonal dynamics in families in which one or more members continue to smoke following diagnosis.
Research Approach: Descriptive, qualitative.
Setting: Three cancer care sites in western Canada.
