POST-TRAUMATIC STRESS DISORDER: A FREQUENT WORK-RELATED ILLNESS
2012
Post-traumatic stress disorder (PTSD) is an anxiety disorder that results from exposure to a traumatic event, and is characterized by hypermnesia of the traumatic event with frequent re-experiencing of the tragic occurrence, hyperarousal, and avoidance behaviour. Depression, anxiety, sleep dysfunction and substance abuse are also commonly reported. PTSD is highly prevalent both in the general population and in certain occupations that are particularly exposed to life-threatening situations, physically and psychological demanding activities, and physical assault, such as rescue workers, firefighters and paramedics. Recent advances in the comprehension of the epidemiology, physiopathology and…
Sleep–wake problems in patients with amyotrophic lateral sclerosis: implications for patient management. NEURODEGENERATIVE DISEASE MANAGEMENT
2012
SUMMARY Sleep–wake problems are frequent, although unrecognized, complications of amyotrophic lateral sclerosis (ALS). Sleep disorders such as insomnia, sleep-disordered breathing and restless legs syndrome have all been reported in patients with ALS, despite the limited number of studies and the small populations investigated so far. Sleep disturbances gradually worsen with disease progression, suggesting a relationship between the severity of disease and the neurodegenerative process. However, poor sleep can also be a consequence of several disturbances such as anxiety, depression, pain, choking, sialorrhea, fasciculations, cramps, nocturia and the inability to get comfortable and move fr…
Understanding short- and long-term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company
2010
Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long-term sustainable policies quite difficult. In fact, the result may be that decision makers introduce "effective" policies in a company subsystem, while ignoring the medium- and long-term implications of such decisions in the performance of the whole company. With the aim to detect the main causes underlying "myopic" fleet maintenance polici…
Immediate bleeding complications in dental implants: A systematic review
2014
Objective: A review is made of the immediate or immediate postoperative bleeding complications in dental implants, with a view to identifying the areas of greatest bleeding risk, the causes of bleeding, the length of the implants associated with bleeding, the most frequently implicated blood vessels, and the treatments used to resolve these complications. Material and Methods: A Medline (PubMed) and Embase search was made of articles on immediate bleeding complications in dental implants published in English up until May 2014. Inclusion criteria: studies in humans subjects with severe bleeding immediately secondary to implant placement, which reported the time until the hemorrhage, the impl…
<p>Clinical Phenotype and Response to Different Lines of Therapy in Elderly with Immune Thrombocytopenia: A Retrospective Study</p>
2020
Purpose Insufficient knowledge of primary immune thrombocytopenia purpura (ITP) in the elderly, together with a lack of clinical trial data, has resulted in wide variation in treatments. Here, we present a study focused on clinical characteristics of ITP in older subjects at diagnosis integrated with the subsequent course of the disease and treatment history. Methods In a retrospective monoinstitutional study, we evaluated >65-year-old patients with primary ITP. Clinical characteristics at the time of diagnosis were described and analyzed. We aimed to delineate whether subsequent lines of therapy influenced the number of relapses. In addition to initial regimens, we reported subsequent trea…
The effects of using participatory working time scheduling software on working hour characteristics and wellbeing : a quasi-experimental study of irr…
2020
Background: Studies in the health care sector indicate that good work time control is associated with better perceived wellbeing but also with non-ergonomic work schedules, such as compressed work schedules. Participatory working time scheduling is a collaborative approach to scheduling shift work. Currently, there is a lack of information on whether working hour characteristics and employees' wellbeing in irregular shift work change after implementing participatory working time scheduling. Objective: To investigate the effects of using digital participatory working time scheduling software on working hour characteristics and well-being among Finnish hospital employees. Participants and met…
Sickness Absence at Work and Supporting Being Present At Work, Among Employees Working Different Shifts in the Forest Industry
2015
Objective: Shift work has negative effects on employee overall health, including sleep disorder, depressive symptoms, and cardiovascular and metabolic diseases. The association between shift work and the prevalence of sickness absence has been less studied. This study investigated sickness absence among employees working different work shift schedules in the forest industry. Method: This descriptive cross-sectional study used employee (N=636) data from forest industry sick-leave registers. The study population (n=280; women n=90 and men=189) worked five different shifts. Each of the five shifts was analyzed separately for sickness absence rate and the results were compared using independent…
The region 0.7615-0.796 m.u. of the HSV-1 genome determines suppression of humoral antibody formation against herpes simplex virus.
1991
The influence of genetic properties of parts of the HSV-1 genome on suppression of humoral antibody formation was investigated by using intratypic recombinants. The deleted strain HFEM (HSV-1) induces suppression. The MluI DNA fragment (coordinates 0.7615–0.796 m.u.) derived from the antibody inducing strain F1 (HSV-1) was transfected into the deleted strain HFEM to produce the recombinant virus R-MlCI and shown to restore antibody formation, as demonstrated by neutralization- and ELISA-tests. The intratypic recombinant viruses R-15, R-19 and R-26, produced by transfection of the Bam HI DNA-fragment B (0.738–0.809 m.u.) of strain Fl into the deleted strain HFEM, resulted in antibody formati…
Nanosecond pulsed electric field inhibits malignant melanoma growth by inducing the change of systemic immunity
2019
Background Nanosecond pulsed electric fields (nsPEFs) showed an inhibitory effect on proliferation of malignant melanoma. In this study, the growth of melanoma were inhibited by changing the systemic immunity. Material and Methods C57BL/6 mice with B16 malignant were exposed to 200 pulses of 100 ns duration, 30kV/cm. The mice were executed four days later. T lymphocyte has been extracted from spleen. Cell viability was evaluated by CCK-8 assay. CD3+CD4+ T cells, CD3+CD8+ T cells, regulatory T cells (Treg) and myeloid-derived suppressor cells (MDSC) were analyzed by flow cytometry. TNF-α, IL-2, IL-10, TGF-β, IFN– γ levels in supernatants were assessed by ELISA. Results C57 malignant melanoma…
