Hepatitis C virus RNA profiles in chronically infected individuals: do they relate to disease activity?

1999

Fluctuations of hepatitis C virus (HCV)-RNA serum levels were monitored in a multicenter study in 76 chronic HCV carriers who had been followed longitudinally without receiving antiviral therapy to assess their relation with the course of liver disease activity. Forty-four patients had normal transaminases over more than 2 years, while 32 additional patients had fluctuating levels. Viral load was measured in serial serum samples prospectively collected for 10 to 12 months in 54 patients and in sera stored yearly up to 8 years in an additional 22 patients. In patients tested monthly, a lesser extent of fluctuations was detected in cases with constantly normal transaminases as compared with t…

Hostility, unemployment and health status: testing three theoretical models.

2003

This study examined three theoretical models of hostility, health and life context. According to the psychosocial vulnerability hypothesis, there is an interaction between hostility and adverse conditions. The increased health risk in hostile individuals is assumed to stem from their lower ability to benefit from existing psychosocial resources. The second hypothesis, called here the social context model, considers adverse conditions as an antecedent of both hostility and health problems. The third model states that hostility is a predictor of being selected to adverse conditions involving risk to health (the selection hypothesis). The results from a survey of a population-based random samp…

"Readiness to Change" Predicts Efficacy of Reduction among Smokers with Severe Mental Illness.

2018

<b><i>Aims:</i></b> Smoking cessation in subjects with a severe mental illness (SMI) is a challenging but attainable goal. Furthermore, the identification of variables involved in the quitting process is a highly relevant factor in clinical practice. This study aimed to analyze the influence of smokers’ motivation in smoking reduction and cessation and select the most suitable way of measuring motivation. <b><i>Methods:</i></b> This is a secondary analysis of a 9-month, multicenter trial examining a Multicomponent Smoking Cessation Program in 82 adult outpatients with SMI. At the end of the preparation stage, the smokers’ motivational level wa…

Systemic vascular resistance predicts the development of hypertension: the cardiovascular risk in young Finns study

2020

To study whether systemic hemodynamics, especially systemic vascular resistance, predicts the development of hypertension and improves the risk prediction of incident hypertension beyond common risk factors in the risk models in young adults.Typical risk factors for hypertension in the risk prediction models (systolic and diastolic blood pressure, parental history of hypertension, age, sex, body-mass index, smoking), laboratory values (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, C-reactive protein), heart rate (HR), stroke index (SI), and systemic vascular resistance index (SVRI) calculated by whole-body impedance cardiography …

State dependent posterior hippocampal volume increases in patients with major depressive disorder.

2011

Abstract Background The hippocampal formation has been implicated in etiology and therapy response in major depressive disorder (MDD). However, prospective longitudinal studies investigating volumes in hippocampal subregions and their association with clinical findings are still lacking. Methods Global and regional hippocampal volumes and neuropsychological performance were assessed longitudinally in 15 young patients with unipolar early onset MDD who responded to therapy and 13 matched healthy control subjects. Results Although volumes at baseline did not differ between groups, patients with MDD showed significant posterior hippocampal volume increases during the treatment course (mean obs…

[Prognostic value of interleukin 6 for death of patients with sepsis].

2016

Abstract Background and objective To see the influence of interlukin-6 (IL-6) as an inflammatory mediator in patients with systemic inflammatory response syndrome (SIRS) and sepsis, assessing whether their serum levels during their stay in intensive care unit (ICU) serve as an early mortality prognostic marker. Material and methods A prospective observational cohort study with 203 ICU patients from a third level hospital. A descriptive analysis was made, X 2 test used to compare qualitative variables, T -Student test to compare quantitative ones. We made a logistic regression multivariant analysis on admission, third and seventh day of stay with dependent variable mortality and independent …

Normal reference values of multilayer longitudinal strain according to age decades in a healthy population: A single-centre experience.

2017

Aims Recent advancements in echocardiographic technology allow to analyse myocardial strain in multiple layers. Little is known about the impact of age on layer-specific longitudinal strain in healthy subjects. The aim of this study was to analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Methods and results Two-hundred sixty-six healthy, consecutive subjects (mean age = 39.2 ± 17.5 years, women/men = 137/129), free of cardiovascular risk factors, were enrolled. S…

3D echocardiographic reference ranges for normal left ventricular volumes and strain: results from the EACVI NORRE study

2017

International audience; Aim: To obtain the normal ranges for 3D echocardiography (3DE) measurement of left ventricular (LV) volumes, function, and strain from a large group of healthy volunteers. Methods and results: A total of 440 (mean age: 45 ± 13 years) out of the 734 healthy subjects enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study had good-quality 3DE data sets that have been analysed with a vendor-independent software package allowing homogeneous measurements regardless of the echocardiographic machine used to acquire the data sets. Upper limits of LV end-diastolic and end-systolic volumes were larger in men (97 and 42 mL/m2)…

Visual memory dysfunction as a neurocognitive endophenotype in bipolar disorder patients and their unaffected relatives. Evidence from a 5-year follo…

2019

BACKGROUND: Scarce research has focused on Visual Memory (VM) deficits as a possible neurocognitive endophenotype of bipolar disorder (BD). The main aim of this longitudinal, family study with healthy controls was to explore whether VM dysfunction represents a neurocognitive endophenotype of BD. METHODS: Assessment of VM by Rey-Osterrieth Complex Figure Test (ROCF) was carried out on a sample of 317 subjects, including 140 patients with BD, 60 unaffected first-degree relatives (BD-Rel), and 117 genetically-unrelated healthy controls (HC), on three occasions over a 5-year period (T1, T2, and T3). BD-Rel group scores were analyzed only at T1 and T2. RESULTS: Performance of BD patients was sig…

A prospective study of the precursors to problem drinking in young adulthood.

1994

This study was part of the Jyvaskyla Longitudinal Study on Social Development. The subjects (196 males, 173 females) were studied at age 8, 14 and 26. Three components in drinking habits were obtained at age 26: social, problem and controlled drinking. Moderate to severe problem drinking was obtained for 26% of the men and 1% of the women, and mild problem drinking for 23% of the men and 15% of the women. Problem drinking (defined by the CAGE Questionnaire, arrest for alcohol abuse and other indicators of heavy drinking) was directly accounted for by poor school success at age 14 and, for men, by conduct problems and low anxiety. Variables at age 8 that contributed indirectly to adult probl…
