The role of stress in the onset of depressive disorders

2002

Background: We conducted the present study to evaluate the impact of stressful events on the onset of depressive disorders in a Spanish clinical sample, compared to a control group matched for age, sex, civil status and social class. We compared our results with those of other studies carried out with samples that were both clinically and culturally similar to ours. Method: Fifty depressed patients that were diagnosed with a depressive episode in the 6 months prior to the interview and 50 healthy controls were included in the study. Both groups were compared on the “Life Events and Difficulties Schedule” (LEDS). Results: Of the depressive patients, 68 % compared to only 18 % of the control …

Epidemiology of Usher Syndrome in Valencia and Spain

2004

<b>Objective:</b> To obtain epidemiological data on the prevalence of the different types of Usher syndrome (US) in Spain, since these data were missing; to estimate the proportion of sporadic cases among simplex families, and calculate the prevalence of the Usher syndrome in a homogeneous population from Eastern Spain (3,875,234 inhabitants) that is representative of the Spanish population. <b>Methods:</b> Otological, ophthalmological and genetic studies were performed in 89 US patients from 46 families and subjected to statistical and segregation analysis. <b>Results:</b> 41.6% of them suffered US type I, 46.1% type II, and in 12.3% the classification r…

Hypothenar hammer syndrome: A multicenter case-control study

2013

Background The rarely diagnosed hypothenar hammer syndrome (HHS) is due to vascular damage to the distal part of the ulnar artery probably caused by acute or repetitive blunt trauma to the hypothenar region. To date, mainly case reports have been published, while epidemiological data are almost absent. Aim To identify potential risk factors for HHS. Method An interview-based multicenter case–control study of 71 patients with HHS and 105 matched controls was conducted with standardized questions regarding disease specific variables, occupation, exposure of the hands to different types of trauma in occupational and leisure context. Medical data were verified from individual medical records. R…

Minority status and perceived health: a comparative study of Finnish- and Swedish-speaking schoolchildren in Finland

2000

Results of earlier studies suggest that the health of the Swedish-speaking minority in Finland is better than that of the sociodemographically similar Finnish-speaking population. The causes of differences are unknown. The main aim of the study referred was to investigate whether differences in perceived health according to linguistic group were present in a nation-wide representative sample (n=5,230) of schoolchildren aged 11, 13 and 15 years. A further aim was to determine whether differences could be attributed to socioeconomic background, social relationships or health behaviour. The study is part of the international Health Behaviour in School-aged children (HBSC) survey. The perceive…

On the Number of Measurements Necessary to Assess Regional Cerebral Blood Flow by Local Laser Doppler Recordings: A Simulation Study with Data from 4…

1995

Laser Doppler fluxmetry may improve the monitoring of cortical blood flow in neurosurgical patients. So far, however, the variability of laser Doppler readings found in the cerebral cortex has prevented a consequent usage of the technique in clinical practice. The current report analyzes the regional variability of laser Doppler readings from experimental animals. Typical frequency histograms of observed flow values display non-Gaussian distributions. A simulation technique is used to assess the number of measuring sites required for valid estimates of regional cortical flow. From a total of 990 local flow measurements from 45 rabbits random samples of sizes between 5 and 100 were repeatedl…

Influence of ABO blood group on sports performance

2017

Background: Despite being a recessive trait, the O blood group is the most frequent worldwide among the ABO blood types. Since running performance has been recognized as a major driver of evolutionary advantage in humans, we planned a study to investigate whether the ABO blood group may have an influence on endurance running performance in middle-aged recreational athletes. Methods: The study population consisted of 52 recreational, middle-aged, Caucasian athletes (mean age: 49±13 years, body mass index, 23.4±2.3 kg/m 2 ), regularly engaged in endurance activity. The athletes participated to a scientific event called “Run for Science” (R4S), entailing the completion of a 21.1 km (half-marat…

Infradian rhythms of serotonin and serotonin‐N‐acetyltransferase in the pineal gland of male rats

1983

Abstract The present investigation was carried out to determine whether in the pineal gland of male Sprague‐Dawley rats infradian rhythms with respect to serotonin, serotonin‐N‐acetyltransferase (NAT) activity, and hydroxyindole‐O‐methyltransferase (HIOMT) can be detected. The serotonin data obtained over a period of 4 weeks and subjected to power spectral analysis suggest the presence of infradian rhythms in the range of 6 and 4.3 days. NAT activity, obtained over a period of 28 days, revealed a 7‐day‐rhythm. A second peak occurring at 2.3 days remained just below the significance limit. HIOMT activity studied over a period of 8 days showed no statistically significant differences between …

Updated diagnosticprognostic paradigm for CAD: a narrative review.

2020

Cardiovascular diseases are the first cause of death globally; early detection of coronary artery disease (CAD) is a challenge for clinicians and radiologists. Over the past 2 decades there have been several improvements in the methods for the assessment of diagnosis and prognosis in patients with suspected CAD; most of these methods are imaging methods and they operate with high-end technologies. Cardiac computed tomography (CCT) as we know it today was introduced in 1998 and has ever progressed with constant pace. The first decade was the technical validation phase of the method while the second decade was the clinical validation phase. CCT has developed an excellent diagnostic and progno…
