This study investigated functional constipation and risk factors affecting older people living in Shahreza, Iran. MATERIALS AND METHODS: This cross-sectional study was performed on 200 older people in Shahreza. They were selected by simple random sampling. We used the Rome III Criteria, the Elderly Physical Activity Questionnaire (PASE), and related questions from the SIB system (integrated health system)...

Ceria nanoparticles (CeO2 NPs) have become popular materials in biomedical and industrial fields due to their potential applications in anti-oxidation, cancer therapy, photocatalytic degradation of pollutants, sensors, etc. Many methods, including gas phase, solid phase, liquid phase, and the newly proposed green synthesis method, have been reported for the synthesis of CeO2 NPs. Due to the wide application of CeO2 NPs, concerns about their adverse impacts on human health have been raised. This review covers recent studies on the biomedical applications of CeO2 NPs, including their use in the treatment of various diseases (e...

OBJECTIVE: This study aimed to evaluate the cost-utility of the addition of vericiguat for treating chronic heart failure (CHF) in China from the healthcare payer's perspective. METHODS: A Markov model was built to estimate the cost and utility of treating CHF using vericiguat plus standard treatment (vericiguat group) vs. standard treatment alone (standard treatment group). The clinical parameters (mortality of cardiovascular and hospitalization rate of HF) were calculated according to the VICTORIA clinical trial...

BACKGROUND: Restoring shoulder function is critical for upper-extremity rehabilitation following a stroke. The complex musculoskeletal anatomy of the shoulder presents a challenge for safely assisting elevation movements through robotic interventions. The level of shoulder elevation assistance in rehabilitation is often based on clinical judgment. There is no standardized method for deriving an optimal level of assistance, underscoring the importance of addressing abnormal movements during shoulder elevation, such as abnormal synergies and compensatory actions...

While ipsilesional cortical electroencephalography has been associated with post-stroke recovery mechanisms and outcomes, the role of cerebellum and its interaction with the ipsilesional cortex is still largely unknown. We have previously shown that post-stroke motor control relies on increased cortico-cerebellar coherence (CCC) in the low beta band to maintain motor task accuracy and to compensate for decreased excitability of the ipsilesional cortex. We now extend our work to investigate corticocerebellar network changes associated with chronic stimulation of the dentato-thalamo-cortical pathway aimed at promoting post-stroke motor rehabilitation...

This study describes electroencephalography (EEG) measurements during a simple finger movement in people with stroke to understand how temporal patterns of cortical activation and network connectivity align with prolonged muscle contraction at the end of a task. We investigated changes in the EEG temporal patterns in the beta band (13-26 Hz) of people with chronic stroke (N = 10, 7 F/3 M) and controls (N = 10, 7 F/3 M), during and after a cued movement of the index finger...

Cerebellar strokes induce coordination disorders that can affect activities of daily living. Evidence-based neurorehabilitation programs are founded on motor learning principles. The cerebellum is a key neural structure in motor learning. It is unknown whether and how well chronic cerebellar stroke individuals (CCSIs) can learn to coordinate their upper limbs through bimanual motor skill learning. The aim was to determine whether CCSIs could achieve bimanual skill learning through a serious game with the REAplan® robot and to compare CCSIs with healthy individuals (HIs)...

BACKGROUND: Cerebrovascular accident dramatically impacts patients' lives. However, this chronic disease could be managed by boosting self-care and following healthy behaviors. Accordingly, this trial sought to specify the impact of a training program established on the theory of planned behavior on the self-care of clients with this condition. MATERIALS AND METHODS: This trial was performed on 80 clients, who were selected using a random numbers table and divided into two equal groups to receive either usual care alone or usual care plus a training program based on the theory of planned behavior (five in-hospital individual sessions for 5 weeks and weekly phone follow-ups for 2 months after discharge)...

Methamphetamine (meth) is a potent and addictive central nervous system stimulant with increasing use. Stroke is one severe possible complication of meth use. Due to high levels of manufacturing in Mexico, the western United States has experienced greater consequences of meth use. The literature reviewed herein is comprised of case studies and series, and it suggests that hemorrhagic stroke (including hypertensive-like intracerebral hemorrhage and aneurysmal subarachnoid hemorrhage), as opposed to ischemic stroke, is the more common type of neurovascular complication of meth use...

BACKGROUND/PURPOSE: To evaluate the impact of coronary artery disease (CAD), percutaneous coronary intervention (PCI), and coronary lesion complexity on outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis. METHODS/MATERIALS: This retrospective study included 1042 patients divided into two groups by the presence or absence of CAD (SYNTAX score 0, no history of revascularization). Propensity score matching was used to compare the two groups...

OBJECTIVES: Despite rising rates of multimorbidity, existing risk assessment tools are mostly limited to a single outcome of interest. This study tests the feasibility of producing multiple disease risk estimates with at least 70% discrimination (area under the receiver operating curve, AUROC) within the time and information constraints of the existing primary care health check framework. DESIGN: Observational prospective cohort study SETTING: UK Biobank. PARTICIPANTS: 228 240 adults from the UK population...

Transcranial direct current stimulation (tDCS) may facilitate neuroplasticity but with a limited effect when administered while stroke patients are at rest. Muscle-computer interface (MCI) training is a promising approach for training stroke patients even if they cannot produce overt movements. However, using tDCS to enhance MCI training has not been investigated. We combined bihemispheric tDCS with MCI training of the paretic wrist and examined the effect of this intervention in chronic stroke patients. A crossover, double-blind, randomized trial was conducted...

BACKGROUND: Hybrid coronary revascularization (HCR) is a treatment approach that combines the benefits of coronary artery bypass grafting (CABG) techniques such as minimally invasive direct coronary artery bypass (MIDCAB) or minimally invasive multivessel CABG (MICS-CABG) with percutaneous coronary intervention (PCI) for carefully selected patients with multivessel coronary artery disease (MV CAD). The extant body of research primarily concentrates on the comparison of outcomes between HCR and CABG or PCI...

BACKGROUND: Chronic lung and heart diseases are more likely to lead an intensive end point after stroke onset. We aimed to investigate characteristics and outcomes of endovascular thrombectomy (EVT) in patients with acute large vessel occlusion stroke (ALVOS) and identify the role of comorbid chronic cardiopulmonary diseases in ALVOS pathogenesis. METHODS: In this single-center retrospective study, 191 consecutive patients who underwent EVT due to large vessel occlusion stroke in neurological intensive care unit were included...

OBJECTIVE: Walking pace is associated with risks of major chronic diseases including cancer, cardiovascular disease (CVD) and diabetes mellitus type 2 (T2DM) in the general population. However, whether increasing walking pace could reduce risks of major chronic diseases in individuals with hypertension remains to be explored, and the underlying mechanism potentially mediated by low-grade inflammation is also unclear. METHODS: A total of 160,470 participants with hypertension were included based on the UK Biobank...

Microglia and astrocytes are key players in neuroinflammation and ischemic stroke. A1 astrocytes are a subtype of astrocytes that are extremely neurotoxic and quickly kill neurons. Although the detrimental A1 astrocytes are present in many neurodegenerative diseases and are considered to accelerate neurodegeneration, their role in the pathophysiology of ischemic stroke is poorly understood. Here, we combined RNA-seq, molecular and immunological techniques, and behavioral tests to investigate the role of A1 astrocytes in the pathophysiology of ischemic stroke...

Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder and dopaminergic dysfunction in the prefrontal cortex (PFC) may play a role. Our previous research indicated that theobromine (TB), a methylxanthine, enhances cognitive function in rodents via the PFC. This study investigates TB's effects on hyperactivity and cognitive function in stroke-prone spontaneously hypertensive rats (SHR), an ADHD animal model. Male SHRs (6-week old) received a diet containing 0.05% TB for 40 days, while control rats received normal diets...

BACKGROUND: Type 2 diabetes mellitus (DM) remains the most common type of DM and is associat-ed with disabling complications, reduced quality of life and reduced life expectancy. Satisfactory control of carbohydrate metabolism remains the key way to manage them. AIM: To perform a retrospective analysis of carbohydrate metabolism (in terms of glycated hemoglobin - HbA1c ), the prevalence of complications, and features of hypoglycemic and concomitant therapy in patients with type 2 DM...

BACKGROUND: Over 1 billion people worldwide suffer from the common chronic medical condition of hypertension. A hypertensive crisis occurs when blood pressure exceeds 180/110 mmHg. Depending on whether the target organ is harmed, the situation may be presented as a hypertensive emergency or urgency. OBJECTIVE: To assess the prevalence and risk factors of patients with hypertensive crises who visited the Emergency Outpatient Department (EOPD) at Adama Hospital Medical College in Adama, Oromia, Ethiopia, between January 01 and August 31, 2021, G...
