Clinical observations and risk factors for tinnitus in a Sicilian cohort.
2014
The aims of this study were to determine the distribution of risk factors associated with tinnitus analysing their role in the development of tinnitus and the effects of their interaction; to evidence the importance of a suitable and adequate clinical and audiologic assessment to avoid those modifiable risk factors responsible for cochlear dysfunction and tinnitus onset. 46 subjects with tinnitus and 74 controls were studied according to: age, sex, Body Mass Index (BMI), neck circumference, tobacco smoking, feeling fatigue or headache, self reporting snoring, hypertension, diabetes, coronary heart disease, and/or hyperlipidemia, and laboratory finding as lipid profile and levels of reactive…
Sudden Sensorineural Hearing Loss: Results of intratympanic steroids as salvage treatment
2012
Objective: The aim of the present study was to verify the efficacy and the safety of intratympanic dexamethasone to treat sudden sensorineural hearing loss as salvage therapy. Materials and methods: A prospective study was conducted on patients affected by idiopathic sudden hearing loss who were treated before with some systemic therapy, but without recovery of the hearing The patients able to undergo the study, but who refused salvage treatment were considered as control group. A solution of Dexamethasone 4 mg/ml was then injected through the posterior–inferior quadrant filling completely the middle ear. The follow-up in the following 6 months included an audiogram every month. Results: Th…
Pulmonary embolism location is associated with the co-existence of the deep venous thrombosis.
2019
Multiple studies have shown that in approximately half of individuals with pulmonary embolism (PE), the deep venous thrombosis (DVT) is not evident at the moment of PE diagnosis. The underlying factors and the origin of PE in these patients are not completely understood: missed DVT, embolization of DVT in its entirety, or de-novo PE being possible explanations. The aim of this study was to evaluate the differences in PE patient with or without co-existing DVT. Sixty-three consecutive PE patients were included. Whole leg bilateral Doppler compression ultrasound was performed to all patients. The PE location and extension, C-reactive protein, platelet count, hemostatic markers FV, FVIII, FXII…
The effect of swinging the arms on muscle activation and production of leg force during ski skating at different skiing speeds
2016
The study investigated the effects of arm swing during leg push-off in V2-alternate/G4 skating on neuromuscular activation and force production by the leg muscles. Nine skilled cross-country skiers performed V2-alternate skating without poles at moderate, high, and maximal speeds, both with free (SWING) and restricted arm swing (NOSWING). Maximal speed was 5% greater in SWING (P<0.01), while neuromuscular activation and produced forces did not differ between techniques. At both moderate and high speed the maximal (2% and 5%, respectively) and average (both 5%) vertical force and associated impulse (10% and 14%) were greater with SWING (all P<0.05). At high speed range of motion and angular …
The role of obesity and physical activity in non-specific and radiating low back pain: The Young Finns study
2013
Objective To study the effects of obesity, physical activity, and change in physical activity on the incidence of low back pain and explore whether obesity modifies the effects of physical activity. Methods As part of the ongoing Young Finns Study, 1224 subjects aged 24–39 years free from low back pain during the preceding 12 months at baseline in 2001 were included. Obesity was defined based on the body mass index (BMI) and waist circumference, and physical activity was assessed by the metabolic equivalent of task (MET) index in 2001 and 2007. Results Abdominal obesity, defined by an increased waist circumference, was associated with an increased incidence of radiating low back pain (adjus…
Muscle inactivity is adversely associated with biomarkers in physically active adults.
2015
PURPOSE While the lack of muscular activity is a proposed trigger for metabolic alterations, this association has not been directly measured. We examined the associations between EMG-derived muscle inactivity and activity patterns and cardiometabolic biomarkers in healthy, physically active adults. METHODS Data for this cross-sectional study were pooled from two studies (EMG24 and InPact), resulting in a sample of 150 individuals without known chronic diseases and with high-quality EMG data (female n = 85, male n = 65, age = 38.8 ± 10.6 yr, body mass index = 23.8 ± 3.1 kg·m⁻²). EMG was measured during one to three typical weekdays using EMG shorts, measuring quadriceps and hamstring muscle …
The relationship between functional disability and health-related quality of life in patients with a rotator cuff tear
2012
To determine the relationship between functional disability and health-related quality of life (HRQoL) in rotator cuff tear (RCT) patients.In 67 RCT patients (mean age, 54 years; 57% males), functional disability was self-reported with the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), HRQoL with the Short-Form 36 Health Survey (SF-36), and pain by visual analogue scale. ASES results were divided into tertiles (12-38, 39-51, and 52-82).Mean ASES score was 48 (range, 12-82). Patients with the highest functional disability and highest pain level had the lowest HRQoL. For the highest, middle, and lowest ASES categories, respectively, mean SF-36 Physical Comp…
Increased cross-education of muscle strength and reduced corticospinal inhibition following eccentric strength training.
2015
Aim: Strength training of one limb results in a substantial increase in the strength of the untrained limb, however, it remains unknown what the corticospinal responses are following either eccentric or concentric strength training and how this relates to the cross-education of strength. The aim of this study was to determine if eccentric or concentric unilateral strength training differentially modulates corticospinal excitability, inhibition and the cross-transfer of strength. Methods: Changes in contralateral (left limb) concentric strength, eccentric strength, motor-evoked potentials, short-interval intracortical inhibition and silent period durations were analyzed in groups of young ad…
High-density electromyography activity in various hamstring exercises
2019
Proximal-distal differences in muscle activity are rarely considered when defining the activity level of hamstring muscles. The aim of this study was to determine the inter-muscular and proximal-distal electromyography (EMG) activity patterns of hamstring muscles during common hamstring exercises. Nineteen amateur athletes without a history of hamstring injury performed 9 exercises, while EMG activity was recorded along the biceps femoris long head (BFlh) and semitendinosus (ST) muscles using 15-channel high-density electromyography (HD-EMG) electrodes. EMG activity levels normalized to those of a maximal voluntary isometric contraction (%MVIC) were determined for the eccentric and concentr…
Associations of disordered sleep with body fat distribution, physical activity and diet among overweight middle-aged men
2015
This cross-sectional study aimed to investigate whether body fat distribution, physical activity levels and dietary intakes are associated with insomnia and/or obstructive sleep apnea among overweight middle-aged men. Participants were 211 Finnish men aged 30-65 years. Among the 163 overweight or obese participants, 40 had insomnia only, 23 had obstructive sleep apnea only, 24 had comorbid insomnia and obstructive sleep apnea and 76 were without sleep disorder. The remaining 48 participants had normal weight without sleep disorder. Fat mass, levels of physical activity and diet were assessed by dual-energy X-ray densitometry, physical activity questionnaire and 3-day food diary, respectivel…
