The timeout procedure in pediatric surgery - effective tool or lip service? A randomized prospective observational study
2020
ABSTRACTBackgroundFor over a decade, the preoperative timeout procedure has been implemented in most pediatric surgery units. In our hospital, a standardized team-timeout is performed before every operation. However, the impact of this intervention has not been systematically studied.PurposeThis study evaluates whether purposefully-introduced errors during the timeout routine are picked up by the operating team members.MethodsAfter ethics board approval and informed consent, deliberate errors were randomly and clandestinely introduced into the timeout routine for elective surgical procedures by a pediatric surgery attending. Errors were randomly selected among wrong name, site, side, allerg…
Disconnected Lives: Trends in Time Spent Alone in Finland
2020
AbstractDiscussions about social isolation have been extensive over the past few decades. A less sociable nature of social ties has been identified in Western societies. The phenomenon has been associated with demographic changes such as aging and living alone as well as changes in the use of new technologies. In this study we employ representative Finnish Time Use Surveys from three decades, 1987–1988 (n = 1887), 1999–2000 (n = 2673) and 2009–2010 (n = 1887) to examine the trends in social isolation, measured as time spent alone. Our results showed that between 1987 and 2010 the time spent alone increased by 124 min per day. The increase was linear and occurred in nearly all population gro…
Validation of two short questionnaires assessing physical activity in colorectal cancer patients
2018
Background In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated. Methods Participants from 'The Norwegian dietary…
Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients: an agreement study
2017
BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments. METHODS: Baseline data f…
Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?
2016
Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…
Causal analysis of short-term cardiovascular variability: state-dependent contribution of feedback and feedforward mechanisms.
2016
Baroreflex function is usually assessed from spontaneous oscillations of blood pressure (BP) and cardiac RR interval assuming a unidirectional influence from BP to RR. However, the interaction of BP and RR is bidirectionalâRR also influences BP. Novel methods based on the concept of Granger causality were recently developed for separate analysis of feedback (baroreflex) and feedforward (mechanical) interactions between RR and BP. We aimed at assessing the proportion of the two causal directions of the interactions between RR and systolic BP (SBP) oscillations during various conditions, and at comparing causality measures from SBP to RR with baroreflex gain indexes. Arterial BP and ECG sig…

5037Drug treatment with beta-blockers and long-term outcome in patients with takotsubo syndrome: results from the takotsubo Italian network
2019
Abstract Background Although generally considered a benign disease, Takotsubo syndrome (TTS) has recently been associated to a substantially comparable long-term outcome than acute coronary syndrome (ACS). The use of beta-blockers (BB) has been advocated in these patients for secondary prevention after the index event, considering the presumed role of catecholamine in TTS pathophysiology. However, the effect of BB on long-term outcome remains controversial due to the paucity of data and the lack of evidence from randomized studies. Purpose To investigate the impact of BB therapy on long-term outcome in patients with TTS. Methods The study included all TTS patients enrolled in the Takotsubo …

Biochemical Aspects of Chick Embryo Retina Development: The Effects of Glucocorticoids
1989
In chick embryo retina during development, DNA synthesis and the activities of DNA polymerase, thymidine kinase, thymidylate synthetase, and ornithine decarboxylase (ODC) declined in parallel from day 7 to 12. The administration in ovo of hydrocortisone reduced significantly, particularly at 8-10 days of incubation, both DNA synthesis and the four enzyme activities tested. The effect was dose dependent, reaching the maximum with 50-100 nmol of hydrocortisone, 8-16 h after treatment. The highest inhibition was found for ODC activity (70%), followed by thymidine kinase activity (62%) and DNA synthesis (45%), whereas activities of DNA polymerase and thymidylate synthetase were reduced only by …
