Acupuncture for Combat-Related Posttraumatic Stress Disorder: A Randomized Clinical Trial.

Importance: Current interventions for posttraumatic stress disorder (PTSD) are efficacious, yet effectiveness may be limited by adverse effects and high withdrawal rates. Acupuncture is an emerging intervention with positive preliminary data for PTSD.

Objective: To compare verum acupuncture with sham acupuncture (minimal needling) on clinical and physiological outcomes.

Conceptualizing a Traditional Chinese Medicine and Pathology of Arousal Diagnostic and Pathophysiological Framework for Postacute Sequelae of COVID-19.

Introduction: The postacute sequelae of COVID-19 (PASC) is a serious heterogeneous condition that affects a significant minority of those who endured COVID-19. PASC involves multiple body systems and an illness trajectory that has stages now being identified in medical research.

Objective: Traditional Chinese Medicine (TCM) and acupuncture are well suited to conceptualize and treat PASC and other postviral conditions.

Improvement in Long-COVID Symptoms Using Acupuncture: A Case Study.

Background: The long-COVID syndrome (LCS), defined by residual symptoms from acute COVID-19 for <60 days, affects about one-third of all COVID survivors and is an emerging public health challenge. Empirical data about the range of symptoms or the utility of acupuncture alone for the LCS are very limited.

Case: This observational case study of a 46-year-old male with LCS was conducted to preliminarily define the range of symptoms, a Traditional Chinese Medicine (TCM) diagnostic structure, and evaluate the potential utility of prescribed acupuncture for LCS.

Technology-Enabled Remote Monitoring and Self-Management - Vision for Patient Empowerment Following Cardiac and Vascular Surgery: User Testing and Randomized Controlled Trial Protocol.

Background: Tens of thousands of cardiac and vascular surgeries (CaVS) are performed on seniors in Canada and the United Kingdom each year to improve survival, relieve disease symptoms, and improve health-related quality of life (HRQL). However, chronic postsurgical pain (CPSP), undetected or delayed detection of hemodynamic compromise, complications, and related poor functional status are major problems for substantial numbers of patients during the recovery process. To tackle this problem, we aim to refine and test the effectiveness of an eHealth-enabled service delivery intervention, TecHnology-Enabled remote monitoring and Self-MAnagemenT-VIsion for patient EmpoWerment following Cardiac and VasculaR surgery (THE SMArTVIEW, CoVeRed), which combines remote monitoring, education, and self-management training to optimize recovery outcomes and experience of seniors undergoing CaVS in Canada and the United Kingdom.

The CD40 agonist antibody CP-870,893 enhances dendritic cell and B-cell activity and promotes anti-tumor efficacy in SCID-hu mice.

CD40 is a member of the TNF family of receptors that has been shown to play a crucial role in enhancing dendritic cell activity and fostering anti-tumor immune responses. In this study, we demonstrate the in vitro properties and in vivo efficacious activity of the CD40 agonist antibody, CP-870,893. CP-870,893 is a fully human, IgG2 antibody that selectively interacts with CD40 at a site distinct from its ligand-binding region with a KD of 0.

PF-03475952: a potent and neutralizing fully human anti-CD44 antibody for therapeutic applications in inflammatory diseases.

Introduction: CD44 is a cell adhesion molecule believed to play a critical role in T cell and monocyte infiltration in the inflammatory process. The reduction of CD44 expression or its ability to properly interact with its key ligand, hyaluronic acid (HA), inhibits migration and subsequent activation of cells within sites of inflammation. CD44-deficient mice exhibit decreased disease in a mouse arthritis model.

Identification of a histamine H4 receptor on human eosinophils--role in eosinophil chemotaxis.

Eosinophils are recruited to sites of inflammation via the action of a number of chemical mediators, including PAF, leukotrienes, eotaxins, ECF-A and histamine. Although many of the cell-surface receptors for these mediators have been identified, histamine-driven chemotaxis has not been conclusively attributed to any of the three known histamine receptor subtypes, suggesting the possibility of a 4th histamine-responsive receptor on eosinophils. We have identified and cloned a novel G protein-coupled receptor (GPCR), termed Pfi-013, from an IL-5 stimulated eosinophil cDNA library which is homologous to the human histamine H3 receptor, both at the sequence and gene structure level.

Interventions used by nursing staff members with psychogeriatric patients resisting care.

Although resistance to care can have a major impact on the provision of care, relatively limited research has been reported on the topic. This research examined differences in the use of interventions by nurses in different care settings to manage resistance to care with eating and dressing. A convenience sample of 50 nurses (34 working in psychiatric hospitals and 16 in nursing homes) participated in the study.

Sexuality among institutionalized elderly patients with dementia.

The subject of sexuality among elderly patients with dementia was examined, focusing on two main aspects: the sexual behaviour of institutionalized elderly people with dementia; and the reactions of other patients, staff and family members to this behaviour. The behaviour was found to be mostly heterosexual and ranged from love and caring to romance and outright eroticism. Reactions varied, being accepting of love and care but often objecting to erotic behaviour.

trans-3-Benzyl-4-hydroxy-7-chromanylbenzoic acid derivatives as antagonists of the leukotriene B4 (LTB4) receptor.

The SAR of a series of 2-(7-chromanyl)benzoic acids has been investigated with the aim of identifying potent and selective LTB4 receptor antagonists that maintain potency in complex biological fluids. We found optimal activity in derivatives with electron-withdrawing groups in the benzoic acid ring and with an unsubstituted C-3 benzyl group on the chromanol nucleus. While compounds containing a 3-(4-phenyl)benzyl chromanol substituent were potent LTB4 receptor antagonists, the increased lipophilicity imparted by the additional phenyl substituent led to decreased potency in the presence of plasma proteins.

The preclinical pharmacological profile of the potent and selective leukotriene B4 antagonist CP-195543.

CP-195543 [(+)-2-(3-benzyl-4-hydroxy-chroman-7-yl)-4-trifluoromethyl-benzoic acid] is a structurally novel, selective and potent leukotriene B4 (LTB4) receptor antagonist. In vitro CP-195543 inhibited [3H]LTB4 binding to high-affinity LTB4 receptors on human neutrophils (HN) and murine spleen membranes with IC50 values of 6.8 nM (Ki = 4.

Feelings of anger among caregivers of patients with Alzheimer's disease.

The purpose of this article is to examine the caregiver's feelings of anger, the causes of these feelings as described by the caregivers and their reactions. Twenty female caregivers of Alzheimer's disease patients participated in a support group at a psychogeriatric centre for 3 years. The group was directed by a registered nurse and a social worker.

A method to record optimum anterior guidance for restorative dental treatment.

An accurate anterior guidance is critical for optimal esthetics, phonetics, comfort, function, stress minimization, and longevity of teeth and restorations. This article describes a method for recording and transferring the anterior guidance information developed on provisional restorations. Felt tip pens were used to mark the static centric relation contacts and the functional disocclusive pathways established on the provisional restorations.

The mirror as a therapeutic tool for patients with dementia.

The aim of the study was to examine changes in patient behavior that occurred as a consequence of looking in a mirror. How do dementia patients relate to their image in the mirror? Is the use of the mirror effective in raising levels of self-awareness, calmness and satisfaction? The survey was carried out on 100 patients suffering from dementia: 67 women and 33 men aged between 67 and 85. The findings showed that most responses to looking in the mirror were positive and raised the patients' awareness regarding self-care.

Effects of crack cocaine on neurocognitive function.

Because crack cocaine appears to have a preferential effect on the metabolic and electrophysiological activity of the frontal and temporal regions of the brain (Pascual-Leone et al., 1991a, 1991b; Volkow, 1992), we hypothesized that cognitive measures of those regions would be impaired in crack cocaine users relative to measures in normal volunteers. We used logistic regression to determine the relationship of cocaine usage to neuropsychological test performance.

Changes in brain glucose metabolism in cocaine dependence and withdrawal.

Objective: The authors investigated changes in brain function associated with cocaine dependence and withdrawal to provide clues regarding the processes that lead to the uncontrollable self-administration of cocaine.

Method: They measured regional brain metabolism with [18F]-fluorodeoxyglucose (FDG) and positron emission tomography in 15 outpatients with the diagnosis of cocaine abuse and 17 normal comparison subjects. Ten of the patients were studied less than 1 week after they had last had cocaine, and five were studied 2-4 weeks after withdrawal.

Effects of chronic cocaine abuse on postsynaptic dopamine receptors.

To assess the effects of chronic cocaine intoxication on dopamine receptors in human subjects, the authors evaluated [18F]N-methylspiroperidol binding using positron emission tomography in 10 cocaine abusers and 10 normal control subjects. Cocaine abusers who had been detoxified for 1 week or less showed significantly lower values for uptake of [18F]N-methylspiroperidol in striatum than the normal subjects, whereas the cocaine abusers who had been detoxified for 1 month showed values comparable to those obtained from normal subjects. The authors conclude that postsynaptic dopamine receptor availability decreases with chronic cocaine abuse but may recover after a drug-free interval.

Changes in axonal transport of phospholipids in the regenerating goldfish optic system.

Changes in axonally transported phospholipids of regenerating goldfish optic nerve were studied by intraocular injection of [2-3H]glycerol 9 days and 16 days after nerve crush at 30 degrees C. The four major glycerophospholipids all showed substantial increases in transported radioactivity above non-regenerating controls at both time points, these being maximal (15- to 35-fold) in the optic nerve-tract at 9 days and about half as great at 16 days. In the contralateral optic tectum transported label increased 6- to 13-fold at 9 days and 10- to 25-fold at 16 days in the various glycerophospholipids.

Intraoperative urinary output does not predict postoperative renal function in patients undergoing abdominal aortic revascularization.

To determine whether intraoperative urinary output was predictive of postoperative renal function, mean urinary output and lowest hourly urinary output were measured in 137 patients during operation for aortic reconstruction. Pulmonary capillary wedge pressure was kept within normal limits. If urinary output was less than 0.

Monitoring with two-dimensional transesophageal echocardiography. Comparison of myocardial function in patients undergoing supraceliac, suprarenal-infraceliac, or infrarenal aortic occlusion.

When the aorta must be temporarily occluded at the suprarenal or supraceliac levels during surgery, the resulting large increase in afterload may make the myocardium ischemic, even though systemic and pulmonary artery pressures and cardiac output are maintained at normal levels. These traditional indices of myocardial well-being do not appear to be sufficiently sensitive, since cardiac complications are still the most frequent cause of perioperative death and morbidity after aortic reconstruction. To evaluate two-dimensional transesophageal echocardiography as a monitor of myocardial well-being, we studied 24 American Society of Anesthesiologists physical status class III or IV adult patients who were undergoing aortic reconstruction and occlusion at the supraceliac (n = 12), suprarenal-infraceliac (n = 6), or infrarenal (n = 6) level.

Ganglioside changes in the regenerating goldfish optic system: comparison with glycoproteins and phospholipids.

Axonally transported radioactivity in sialoglycoconjugates, labeled by intraocular injection of [3H]N-acetylmannosamine, increased significantly during regeneration of goldfish optic axons at 30 degrees C. Ganglioside radioactivity showed the largest increase--approximately eightfold--in the optic nerve tract at 8 days after optic nerve crush while sialoglycoprotein radioactivity increased fourfold under the same conditions. As regeneration proceeded the magnitude of the increase in the nerve tract diminished for both glycoconjugates.
