Clinical effect of toothpaste and mouth rinse containing zinc lactate on oral malodor reduction
2019
Background This study aimed to investigate the effect of toothpaste and mouth rinse containing 0.14% zinc lactate on the reduction of three volatile oral malodor gases. Material and Methods Ten subjects with good health were recruited to take part in a crossover design study with a 7-day washout period. They were randomly assigned to use the test (toothpaste and rinse containing 0.14% zinc lactate) or placebo (negative control) treatment regimens within the two-week period. All subjects were asked to refrain from tooth brushing and eating in the morning prior to the gas collection periods. The assessment of malodor measured the quantity of three volatile sulphur compounds (VSCs) using an Or…
Urinary leukotriene E4 in the assessment of nocturnal asthma
1996
Urinary leukotriene E4 (LTE4) is a marker of the body's production of cysteinyl LTs, important mediators of airway inflammation. The role of the latter in nocturnal asthma is a topic of increasing interest.This investigation was aimed at determining whether nighttime attacks are associated with increased release of LTs, expressed by urinary LTE4, and the relationship between the two phenomena.Three groups were studied: group A, seven control subjects; group B, nine asthmatic patients without nocturnal attacks; and group C, nine asthmatic patients with a comparable daytime FEV1 but who were experiencing nocturnal exacerbations (morning dips in peak expiratory flow greater than 20%). Urine wa…
Changes in cortisol and dehydroepiandrosterone in women victims of physical and psychological intimate partner violence
2003
Background Although intimate partner violence (IPV) has a great impact on women's health, few studies have assessed the consequences on physiologic responses. Methods Women abused by their intimate male partners either physically (n = 70) or psychologically (n = 46) were compared with nonabused control women (n = 46). Information about sociodemographic characteristics, smoking, pharmacologic treatment, lifetime history of victimization (childhood and adulthood), and mental health status (depression, anxiety, and posttraumatic stress disorder, PTSD) was obtained through structured interviews. Saliva samples were collected at 8 am and 8 pm for 4 consecutive days to determine morning and eveni…
Biological Monitoring of Exposure to Benzene in Port Workers
2020
Port workers are exposed to a wide range of occupational hazards that can cause injuries and occupational diseases. Among these, exposure to benzene is one of the most important but least studied. The highest occupational exposures for port workers occur during the filling and loading of gasoline, and cleaning of tanks and receptacles. The aim of the study was to evaluate occupational exposure to low levels of benzene by measuring trans,trans-muconic acid (t,t-MA) in urine samples from workers operating at fuelling stations in a tourist port of Southern Italy. The overall sample was composed of 43 port workers of a tourist port in Southern Italy. In 2018, each participant provided two (morn…
Active recovery shows favorable IGF-I and IGF binding protein responses following heavy resistance exercise compared to passive recovery
2019
IGF-I and IGFBPs have important physiological modulatory effects and this study sought to examine the influence of active vs. passive recovery following a heavy resistance exercise on IGF-I and IGF binding protein (IGFBP) recovery responses. It was hypothesized that increased IGF-I and decreased inhibitory IGFBPs during active recovery may be reflective of cascades promoting physiological recovery. 18 untrained men ((AR n = 7, PR n = 11), age: 26 ± 4 years, height: 174 ± 8 cm, body mass: 75 ± 13 kg) performed either a protocol-specific 10 × 10 × 30% 1RM active (AR) or passive recovery (PR) session following a heavy resistance exercise session performed on a leg press device (10 × 10 1RM). M…
Blood Pressure Response to Physical Activity in Hypertensive Subjects at Different Times of the Day
1976
1. Active orthostasis causes a fall of systolic blood pressure in the morning; this fall was more extensive in severe arterial hypertension. 2. Everyday physical activity produces a marked rise of systolic blood pressure, which is higher at noon and in the evening than in the morning; the hypertensive response is somewhat greater in WHO II and III, than in WHO I, grades of hypertension. 3. In studies on blood pressure behaviour in hypertensive subjects the circadian variability not only of the blood pressure at rest but also of the blood pressure response to various stimuli has to be considered.
Further development of a commercial driving simulation for research in occupational medicine
2012
Objectives: The purpose of this study was to refine a commercial car driving simulation for occupational research. As the effects of ethanol on driving behavior are well established, we choose alcohol as a test compound to investigate the performance of subjects during simulation. Materials and Methods: We programmed a night driving scenario consisting of monotonous highway and a rural road on a Foerst F10-P driving simulator. Twenty healthy men, 19-30 years, participated in a pilot study. Subjects were screened for simulator sickness, followed by training on the simulator one hour in total. Experiments were performed in the morning on a separate day. Participants were randomized into eithe…
The association between night eating and body mass depends on age
2014
Night eating syndrome (NES) is marked by substantial evening or nocturnal food intake, insomnia, morning anorexia, and depressed mood. Originally, NES was described as an eating pattern among obese individuals.However, subsequent studies showed that NES also occurs among non-obese individuals, who appear to be younger than obese individuals with NES. Thus, it has been proposed that NES may lead to future weight gain,which may explain inconsistent findings about associations between NES and body mass. The current study investigated the relationships between age, body mass index (BMI), and night eating severity in a representative sample of German adults (n = 2317). It was found that age mode…
Adrenal morphology and function in acromegalic patients in relation to disease activity.
2009
Visceromegaly is a common consequence of acromegaly. However, few studies investigated the chronic effects of growth hormone on adrenal glands. Our aim was to evaluate adrenal morphology and function in a cohort of acromegalic patients in relation to disease activity. Twenty-six acromegalics (10 males and 16 females) and 21 healthy subjects were investigated. Gland morphology was evaluated by computerized axial tomography, measuring central, lateral, and medial adrenal segments. Uncontrolled acromegalics showed increased volume of all adrenal segments, higher urinary free cortisol (UFC), and lower morning adrenocorticotropic hormone in comparison with healthy subjects. However, normal corti…
Prevalence of glaucoma and distribution of intraocular pressure in a population. The Casteldaccia Eye Study.
2009
IOP was measured in 1062 middle-aged and elderly subjects of a small Sicilian town, enrolled in a population based survey. The mean IOP was 15.1 +/- 3.7 mmHg without interocular or sex differences. A small but significant age-dependent increase of IOP was found. Circadian and seasonal influences were recorded: IOP was higher in the morning and in winter. The prevalence of chronic open-angle glaucoma was 1.2%, but it grew to 3.6 if only subjects aged 70 years or more were considered. IOP of 24 mmHg or more was found in 2.7%, while 4.3% of subjects showed IOP of 21 mmHg or more. This survey shows that mean IOP of the Mediterranean population studied is similar to the IOP found in other epidem…
