BACKGROUND: Alzheimer's disease (AD) is the leading cause of degenerative dementia in the aging population. Patients with AD have alterations in cerebral hemodynamic function including reduced cerebral blood flow (CBF) and cerebral metabolic rate. Therefore, improved cerebrovascular function may be an attractive goal for pharmaceutical intervention in AD. OBJECTIVE: We wished to observe the acute effects of sildenafil on cerebrovascular function and brain metabolism in patients with AD...

BACKGROUND: Sleep disturbance is the second most bothersome symptom in patients with cancer, and it can significantly impair their quality of life. The aim of this study was to investigate the efficacy and safety of the traditional herbal medicine Gamiguibi-tang (GGBT) in patients with cancer-related sleep disturbance. METHODS: We conducted a prospective, randomized, wait-list-controlled, open-label pilot clinical trial on cancer-related sleep disturbance. Patients with cancer experiencing poor sleep quality with a Pittsburgh Sleep Quality Index of at least 6 were randomly assigned to the GGBT and wait-list groups to receive GGBT and conventional care, respectively, for 2 weeks...

OBJECTIVES: Idiopathic rapid eye movement sleep behavior disorder (IRBD) patients are prone to cognitive deficits, which include attention, executive, and visuospatial dysfunctions. Even patients with normal cognition may exhibit subclinical electrophysiological dysfunction. This study aimed to evaluate visuospatial attention processing in IRBD patients with normal cognition and to compare their findings with those of age- and sex-matched healthy controls. METHODS: We recorded event-related potentials (ERPs) and performance measures during a variant of the Posner task in 14 IRBD patients and 14 control subjects...

Rapid-deployment valves could potentially reduce cross-clamping time and cardiopulmonary bypass time in complex combined procedures and facilitate minimally invasive surgery. This propensity-matched study compared clinical and echographic outcomes between patients undergoing rapid-deployment aortic valve replacement (RDAVR) compared with stented biological aortic valve replacement (SAVR), with or without concomitant procedures. Between 2012 and 2015, 61 consecutive patients (age 70 ± 7 years, European System for Cardiac Operative Risk Evaluation [EuroSCORE] II 2...

Background: Mild cognitive impairment (MCI) represents a transition between normal cognitive aging and dementia and may represent a critical time frame for promoting cognitive health through behavioral strategies. Current evidence suggests that physical activity (PA) and sedentary behavior are important for cognition. However, it is unclear whether there are differences in PA and sedentary behavior between people with probable MCI and people without MCI or whether the relationships of PA and sedentary behavior with cognitive function differ by MCI status...

Tobacco and alcohol consumption are the main risk factors for head and neck squamous cell carcinoma (HNSCC). In addition, human papillomavirus (HPV) infection plays a causal role in oropharyngeal cancer (OPC), a subset of HNSCC. We assessed the independent effects of tobacco, alcohol, and HPV infection on OPC risk in the Head and Neck Cancer(HeNCe) Life study, a hospital-based case-control study of HNSCC with frequency-matched controls by age and sex from four Montreal hospitals. Interviewers collected information on socio-demographic and behavioural factors...

INTRODUCTION: Human papillomavirus (HPV), a sexually transmitted infection, can cause anogenital warts and a number of cancers. To prevent morbidity and mortality, three vaccines have been licensed and are recommended by Canada's National Advisory Committee on Immunisation (for girls since 2007 and boys since 2012). Nevertheless, HPV vaccine coverage in Canada remains suboptimal in many regions. This study will be the first to concurrently examine the correlates of HPV vaccine decision-making in parents of school-aged girls and boys and evaluate changes in parental knowledge, attitudes and behaviours over time...

COMMENT
Vyara Valkanova, Klaus P Ebmeier, Charlotte L Allan
Depression and dementia are both common conditions in older people, and they frequently occur together. Late life depression affects about 3.0-4.5% of adults aged 65 and older. Depression occurs in up to 20% of patients with Alzheimer’s disease and up to 45% of patients with vascular dementia. Rather than a risk factor, depression with onset in later life is more likely to be either prodromal to dementia or a condition that unmasks pre-existing cognitive impairment by compromising cognitive reserve. Depression can be a psychological response to receiving a diagnosis of dementia...

From March 2014 to December 2016, a cluster of 13 cases of Campylobacter fetus intestinal and extraintestinal infections, including 2 patients with an aortic mycotic aneurysm, caused significant morbidity. The cluster likely resulted from sexual transmission between men having sex with men living in the greater Montreal area, Quebec, Canada.

Validating support of social participation for people with cognitive impairment (CI) plays a predominant role in maintaining identity, autonomy, sense of belonging and social bonding. Yet what restricts this participation-intervention methods, cognitive impairment, or other individuals in the participant's environment? This study documents stakeholders', volunteers' and users' perceptions of people with CI in community recreation centres (CRC). Six focus groups (n = 44) in Montreal, Quebec City and Drummondville highlighted some issues concerning this subject...

OBJECTIVE: Reliable identification of cognitive impairment in hemodialysis patients is of utmost importance, as it is associated with poor outcomes including dialysis withdrawal and death. High prevalence of cognitive impairment has been demonstrated in several studies using brief screening instruments or neuropsychological test batteries. However, the relevance of cognitive impairment as well as the accuracy of screening procedures have never been studied in this patient population. METHODS: 151 chronic hemodialysis patients (mean age 65...

BACKGROUND: People who inject drugs (PWID) have an elevated risk of suicide attempt. While different substances are associated with suicide attempt, the overall risk posed by binge behavior, a high risk pattern of drug use, remains unclear. Our objective is to assess the association between binge drug use and suicide attempt in a prospective cohort of PWID in Montreal, Canada. METHODS: Participants answered a biannual interviewer-administered questionnaire compiling information on sociodemographics, pattern of substance use (cocaine, amphetamine, opioids, sedative-hypnotics, alcohol and cannabis), psychosocial stressors and related markers...

INTRODUCTION: Studies using functional connectivity and network analyses based on magnetoencephalography (MEG) with source localization are rapidly emerging in neuroscientific literature. However, these analyses currently depend on the availability of costly and sometimes burdensome individual MR scans for co-registration. We evaluated the consistency of these measures when using a template MRI, instead of native MRI, for the analysis of functional connectivity and network topology. METHODS: Seventeen healthy participants underwent resting-state eyes-closed MEG and anatomical MRI...
