Age-related neuromuscular function during drop jumps.
2007
Muscle- and movement-specific fascicle-tendon interaction affects the performance of the neuromuscular system. This interaction is unknown among elderly and consequently contributes to the lack of understanding the age-related problems on neuromuscular control. The present experiment studied the age specificity of fascicle-tendon interaction of the gastrocnemius medialis (GM) muscle in drop jump (DJ) exercises. Twelve young and thirteen elderly subjects performed maximal squat jumps and DJs with maximal rebound effort on a sledge apparatus. Ankle and knee joint angles, reaction force, and electromyography (EMG) from the soleus (Sol), GM, and tibialis anterior (TA) muscles were measured tog…
Heart rate variability related to effort at work
2011
Changes in autonomic nervous system function have been related to work stress induced increases in cardiovascular morbidity and mortality. Our purpose was to examine whether various heart rate variability (HRV) measures and new HRV-based relaxation measures are related to self-reported chronic work stress and daily emotions. The relaxation measures are based on neural network modelling of individual baseline heart rate and HRV information. Nineteen healthy hospital workers were studied during two work days during the same work period. Daytime, work time and night time heart rate, as well as physical activity were recorded. An effort-reward imbalance (ERI) questionnaire was used to assess ch…
Identification of possible risk factors for alcohol use disorders among general practitioners in Rhineland-Palatinate, Germany
2012
QUESTIONS UNDER STUDY Research on alcohol use disorders among physicians has been scarce in Germany. The aim of our study was to identify possible risk factors for alcohol use disorders among general practitioners (GPs) working in the outpatient sector in the federal German state of Rhineland-Palatinate (RP). METHODS An anonymous survey was carried out between June and July 2009. 2,092 practice-based GPs in the federal German state of RP were asked to take part in the cross-sectional study via postal mail. The CAGE screening tool was used in its German version (CAGE-G) to screen for alcohol use disorders (AUD). Moreover, possible risk factors such as work stress (effort-reward imbalance), s…
Clinical follow-up after surgery of lumbar disc prolapses. A critical analysis.
1990
A retrospective clinical study was made on 987 patients with lumbar disc disease treated by discectomy. All patients had been operated on in the Department of Neurosurgery (University-Hospital Mainz). 545 patients were males, and 442 females (1.2:1). Patients in the 4th decade of life were affected most often (33.5%). Perioperative complications occurred in 5.4%, with discitis as the single major complication (1.9%). 83% of all patients who underwent discectomy could return to their normal occupation.
Chronic subdural hematoma--craniotomy versus burr hole trepanation.
2009
The authors present a series of more than 200 surgical procedures for chronic subdural hematoma in a 5-year-period. Clinical presentation and neurosurgical treatment were regarded with a special focus on the surgical technique. Between March 2003 and July 2008, 193 patients (113 male and 80 female, mean age 72.5 yrs [range 26–97 yrs]) suffering from chronic subdural hematoma were retrospectively analyzed. One-hundred-fifty-one craniotomies and 42 burr holes were performed. Forty-two craniotomy patients (27.8%) in contrast to 6 burr hole patients (14.3%) required surgical revision. A craniectomy was performed as an ultima ratio after at least 2 prior evacuations in 3 cases. Chronic subdural …
A case-control study on lip cancer risk factors in Ragusa (Sicily).
1984
Incidence rates of lip cancer in males in Ragusa (Sicily) are amongst the highest in Europe [age-standardized rate (world) for 1980-82: 7.5 per 100,000]. A case-control study was conducted on 53 male cases and 106 controls matched for sex, age (+/- 2 1/2 years), residence and hospital from which cases had been drawn. Individual interviews were carried out for the evaluation of ethnic, environmental, pathologic and occupational risk factors. Lip cancer was significantly associated with: fair, brown, or red hair (relative odds = 2.3), blue eyes (r.o. = 5.3), fair skin (r.o. = 8.0), sensitivity to sunburns (r.o. = 4.1), working outdoors (r.o. = 4.9), coexistence of non-specific lesions of expo…
Early life body mass trajectories and mortality in older age: Findings from the Helsinki Birth Cohort Study
2014
Overweight and obesity in childhood have been linked to an increased risk of adult mortality, but evidence is still scarce.We identified trajectories of body mass index (BMI) development in early life and investigated their mortality risk. Data come from the Helsinki Birth Cohort Study, in which 4943 individuals, born 1934-1944, had serial measures of weight and height from birth to 11 years extracted from health care records, weight and height data in adulthood, and register-based mortality data for 2000-2010.Three early BMI trajectories (increasing, average, and average-to-low for men and increasing, average, and low-to-high BMI for women) were identified. Women with an increasing or low-…
Depression in the community: a comparison of treated and non-treated cases in two non-referred samples.
1992
Family studies in non-patient samples may help to clarify whether or not treatment-seeking behaviour is substantially determined by clinical features of depression. Life-time risks of depression were investigated by structured clinical interviews (SADS-LA) in both a high-risk sample of depressed patients' first-degree relatives and an unscreened control sample of the general population: 34.6% of the high-risk sample versus 23.1% of controls were cases of depression, with a female preponderance in both groups. The rates of treated depression were 17.0% versus 8.5%. Female sex, greater age, higher severity of episodes, manic or hypomanic episodes recurrent course, and introverted and anancast…
Riskard 2005. New tools for prediction of cardiovascular disease risk derived from Italian population studies.
2005
Abstract Background and aim The need to update tools for the estimate of cardiovascular risk prompted the “Gruppo di Ricerca per la Stima del Rischio Cardiovascolare in Italia” to produce a new chart and new software called Riskard 2005. Methods and results Data from 9 population studies in 8 Italian regions, for a grand total of 17,153 subjects (12,045 men and 5,108 women) aged 35–74 and for a total exposure of about 194,000 person/years were available. A chart for the estimate of cardiovascular risk (major coronary, cerebrovascular and peripheral artery disease events) in 10 years was produced for men and women aged 45–74 free from cardiovascular diseases. Risk factors employed in the est…
A new risk score to assess atrial fibrillation risk in hypertensive patients (ESCARVAL-RISK Project.
2020
AbstractThis study aimed to assess atrial fibrillation (AF) incidence and predictive factors in hypertensive patients and to formulate an AF risk assessment score that can be used to identify the patients most likely to develop AF. This was a cohort study of patients recruited in primary healthcare centers. Patients aged 40 years or older with hypertension, free of AF and with no previous cardiovascular events were included. Patients attended annual visits according to clinical practice until the end of study or onset of AF. The association between AF incidence and explanatory variables (age, sex, body mass index, medical history and other) was analyzed. Finally, 12,206 patients were includ…
