OBJECTIVES: Comorbid hypertension and hyperhomocysteinemia is an important risk factor for carotid atherosclerotic plaque formation. We put forward the hypothesis that the subjects with comorbid prehypertension and hyperhomocysteinemia also had an increased risk of subclinical atherosclerosis, using carotid intima-media thickness (CIMT) as the marker of the atherosclerotic process. METHODS: A total of 4102 asymptomatic Chinese subjects aged 18-60 years were divided into four groups according to blood pressure (BP) and homocysteine (HCY) level: the control group without prehypertension or hyperhomocysteinemia, isolated prehypertension group, simple hyperhomocysteinemia group and prehypertension with hyperhomocysteinemia group...

INTRODUCTION: Despite having severe Alzheimer disease pathology, some individuals remain cognitively asymptomatic (cASYM). To explore noncognitive manifestations in these cASYM individuals, we aim to investigate the prevalence and pathologic substrates of psychosis. METHODS: Data were obtained from the National Alzheimer's Coordinating Center. The Neuropsychiatric Inventory Questionnaire, quick version was used to evaluate presence of psychosis. Subjects with Mini-Mental Status Examination score of ≥24 with frequent neuritic plaques (NPs) were defined as NPcASYM, and those with Braak and Braak stage of neurofibrillary tangles of V/VI were defined as NTcASYM (both groups collectively designated cASYM)...

Introduction: Alzheimer's disease (AD) is characterized by the presence of amyloid β (Aβ) plaques, neurofibrillary tangles, and neurodegeneration, evidence of which may be detected in vivo via cerebrospinal fluid (CSF) sampling. Physical activity (PA) has emerged as a possible modifier of these AD-related pathological changes. Consequently, the aim of this study was to cross-sectionally examine the relationship between objectively measured PA and CSF levels of Aβ42 and tau in asymptomatic late-middle-aged adults at risk for AD...

We present a 41-year-old woman with itching polymorphic skin lesions involving the trunk and extremities which first appeared in September 2011 (7 years ago). Physical examination revealed multiple erythematous, scaly macules and patches, indurated red plaques and purplish red and smooth surfaced nodules (Fig. 1a). Over the period of seven years, the skin lesions grew slowly and spread across the body but sometimes they regressed either spontaneously or after insolation.

BACKGROUND: Carotid artery plaque is associated with coronary artery disease (CAD). Besides the presence of plaque, plaque characteristics is also related to the severity of CAD. So the characteristic difference of carotid plaque may affect this assessment role. However, it is unclear whether the maximum carotid plaque area can reflect the extents and severity of CAD. METHODS: We enrolled 388 consecutive CAD patients and 45 controls, and 204 patients were studied after excluding 184 patients without carotid plaque or coronary angiogram...

BACKGROUND AND OBJECTIVES: Atherosclerosis is highly prevalent in CKD. The rate of progression of atherosclerosis is associated with cardiovascular events. Fibroblast growth factor 2 (FGF-2) is a member of the FGF family with potentially both protective and deleterious effects in the development of atherosclerosis. The role of circulating FGF-2 levels in the progression of atherosclerosis in CKD is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used a multicenter, prospective, observational cohorts study of 481 patients with CKD...

BACKGROUND: Guttural pouch mycosis (GPM) is a cause of nasal discharge, dysphagia, and fatal haemorrhage in the horse. OBJECTIVES: To report the complications and success of salpingopharyngeal fistulation in horses with GPM. We hypothesised that creating a direct static opening into the guttural pouch from the pharynx would cause a regression of fungal plaques due to a change in the guttural pouch environment and that this treatment would result in resolution of infection prior to secondary complications...
