#1
Marta Broto, Roger Galve, M-Pilar Marco
A NP-based biobarcode for C-reactive protein (CRP) quantification in plasma samples is reported for the first time. The assay uses capture antibody functionalized magnetic beads (pAbCRP2-MP), multifunctional oligonucleotide encoded probes modified with a detection antibody (pAbCRP1-ePSP), and a fluorescent DNA microarray. Thus, magnetic beads are added to the sample to form immunocomplexes that will be isolated, to then add the codified particles to form a sandwich complex with both particles and the target protein, subsequently the complexes are treated to release the oligonucleotide codes, which are finally hybridized in a fluorescent DNA microarray...

IMPORTANCE: Chronic fatigue syndrome (CFS) is characterised by a constellation of symptoms diagnosed with a number of different polythetic criteria. Heterogeneity across these diagnostic criteria is likely to be confounding research into the as-yet-unknown pathophysiology underlying this stigmatised and debilitating condition and may diagnose a disease spectrum with significant implications for clinical management. No studies to date have objectively investigated this possibility using a validated measure of CFS symptoms-the DePaul Symptom Questionnaire (DSQ)...

Cardiovascular disease remains the number one cause of mortality in the United States. There are numerous approaches to treating these diseases, but regardless of the approach, an in vivo model is needed to test each treatment. The pig is one of the most used large animal models for cardiovascular disease. Its heart is very similar in anatomy and function to that of a human. The ameroid placement technique creates an ischemic area of the heart, which has many useful applications in studying myocardial infarction...

Incidence of cardiovascular events follows a circadian rhythm with peak occurrence during morning. Disturbance of autonomic control caused by exercise had raised the question of the safety in morning exercise and its recovery. Furthermore, we sought to investigate whether light aerobic exercise performed at night would increase HR and decrease HRV during sleep. Therefore, the aim of this study was to test the hypothesis that morning exercise would delay HR and HRV recovery after light aerobic exercise, additionally, we tested the impact of late night light aerobic exercise on HR and HRV during sleep in sedentary subjects...

Androgen deprivation therapy continues to be widely used for the treatment of prostate cancer despite the appearance of new-generation androgen-receptor targeting drugs after 2000. Androgen deprivation therapy can alleviate symptoms in patients with metastatic prostate cancer and might have a survival benefit in some patients, but it causes undesirable changes in lipid, glucose, muscle or bone metabolism. These metabolic changes could lead to new onset or worsening of diseases, such as obesity, metabolic syndrome, diabetes mellitus, cardiovascular disease, sarcopenia or fracture...

BACKGROUND: Although 24-hour blood pressure (BP) variability (BPV) is predictive of cardiovascular outcomes independent of absolute BP levels, it is not regularly assessed in clinical practice. One possible limitation to routine BPV assessment is the lack of standardized methods for accurately estimating 24-hour BPV. We conducted a systematic review to assess the predictive power of reported BPV indexes to address appropriate quantification of 24-hour BPV, including the average real variability (ARV) index...

Iatrogenic aortic dissection caused by axillary arterial cannulation or perfusion becomes a fatal complication of cardiopulmonary bypass when surgeons do not recognize it in the surgical field of view immediately during surgery. Therefore, we routinely monitor the aorta using 'triple ultrasonography' during cardiovascular surgery. An 85-year-old woman underwent partial arch replacement for chronic type A aortic dissection. During cardiopulmonary bypass, acute aortic dissection was observed in the aortic arch from the right axillary artery on real-time transoesophageal echocardiography...

OBJECTIVE: Thyroid hormone has well recognized effects on the cardiovascular system. The purpose of this study was to define the influence of treatment of either hypothyroidism and hyperthyroidism on the values and circadial variations of arterial blood pressure measured by ambulatory blood pressure monitoring. MATERIAL AND METHODS: The study was carried out on 30 hypothyroidic and 30 hyperthyroidic patients without hypertension and 46 healthy participants. First, all the parameters of the groups, then blood pressure values obtained by ambulatory blood pressure monitoring before and after treatment (thyroid hormone replacement with levothyroxine and antithyroid treatment either with propylthyrouracil or metimazole) were compared...

OBJECTIVE: To evaluate the impact of olmesartan alone or combined with one to three antihypertensive drugs on 24-h blood pressure variability (BPV) and on distribution of BP reduction in a pooled individual data analysis of 10 double-blind, randomized, ambulatory BP monitoring (ABPM) studies. METHODS: ABPMs were performed before and after 6-12 weeks of treatment with placebo (n = 119), active control monotherapy [n = 1195, angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), dihydropyridine calcium channel blockers (DCCBs)], or DCCBs), olmesartan monotherapy (n = 1410), active control dual combination [n = 79, DCCB + thiazide diuretic (TD)], olmesartan dual combination (n = 637, DCCB or TD), and triple combination therapy (n = 102, DCCB+TD)...

Drug-induced sleep endoscopy (DISE) is a diagnostic technique for 3D dynamic anatomical visualisation of upper airway obstruction during sedated sleep. There is a lack of standardised procedure and objective measurement associated with information capture, information management, evaluation of DISE findings, treatment planning, and treatment outcomes. The objective of this study is to present clinical feasibility results using a DISE DATA FUSION system for capturing, merging, displaying and storing anatomical data from an endoscopic imaging system and cardiorespiratory data from an anaesthesiological monitoring system simultaneously in real-time during DISE...

Most existing non-contact monitoring systems are limited to detecting physiological signs from a single subject at a time. Still, another challenge facing these systems is that they are prone to noise artifacts resulting from motion of subjects, facial expressions, talking, skin tone, and illumination variations. This paper proposes an efficient non-contact system based on a digital camera to track the cardiorespiratory signal from a number of subjects (up to six persons) at the same time with a new method for noise artifact removal...

The ability to characterize the mechanical properties of erythrocytes is important in clinical and research contexts: to diagnose and monitor hematologic disorders, as well as to optimize the design of cardiovascular implants and blood circulating devices with respect to blood damage. However, investigation of red blood cell (RBC) properties generally involves preparatory and processing steps. Even though these impose mechanical stresses on cells, little is known about their impact on the final measurement results...

A novel in-vitro test (T50-test) assesses ex-vivo serum calcification propensity which predicts mortality in HD patients. The association of longitudinal changes of T50 with all-cause and cardiovascular mortality has not been investigated. We assessed T50 in paired sera collected at baseline and at 24 months in 188 prevalent European HD patients from the ISAR cohort, most of whom were Caucasians. Patients were followed for another 19 [interquartile range: 11-37] months. Serum T50 exhibited a significant decline between baseline and 24 months (246 ± 64 to 190 ± 68 minutes; p < 0...

Background: Blood pressure variability (BPV) has been postulated as a potential predictor of cardiovascular outcomes. No agreement exists as to which measurement method is best for BPV estimation. We attempt to assess the correlation between BPV obtained at the doctor's office, self-measurement at home (SMBP) and ambulatory BP monitoring (ABPM). Methods: Eight weekly clinic BP measurements, two SMBP series and one 24-hour ABPM recording were carried out in a sample of treated hypertensive patients...
