Orderly display of limb lead ECGs raises Chinese intern’s diagnostic accuracy when determining frontal plane QRS axis
2019
Background: There is limited information on whether the orderly display of limb lead ECGs (electrocardiograms) can facilitate students to determine frontal plane QRS complex wave electrical axis. Objectives: The study investigated whether the orderly display of limb lead ECGs can raise Chinese undergraduate intern’s diagnostic accuracy when determining frontal plane axis. Design: A total of 147 fifth-year undergraduate interns aged between 21 and 25 years were randomly arranged into 2 groups: one group was given classically displayed ECGs of limb leads while the other group was given orderly displayed ECGs of limb leads. They were then taught to determine frontal plane axis with one of the …
Lower strength of the human posterior patellar tendon seems unrelated to mature collagen cross-linking and fibril morphology
2009
The human patellar tendon is frequently affected by tendinopathy, but the etiology of the condition is not established, although differential loading of the anterior and posterior tendon may be associated with the condition. We hypothesized that changes in fibril morphology and collagen cross-linking would parallel differences in material strength between the anterior and posterior tendon. Tendon fascicles were obtained from elective ACL surgery patients and tested micromechanically. Transmission electron microscopy was used to assess fibril morphology, and collagen cross-linking was determined by HPLC and calorimetry. Anterior fascicles were markedly stronger (peak stress: 54.3 ± 21.2 vs.…
Early viral clearance and sustained response in chronic hepatitis C: a controlled trial of interferon and ribavirin after high-dose interferon induct…
2002
High-dose induction with alpha-interferon induces early viral clearance of hepatitis C and combined with ribavirin enhances sustained response. We assess whether adding ribavirin after viral clearance obtained by alpha-interferon induction increased the rate of viral eradication.Forty-one naïve patients with chronic hepatitis C were randomised to receive, after 4 weeks of 10 mU daily of alpha-interferon (induction), 3 mU daily for 22 weeks and 3 mU thrice weekly for 26 weeks of either interferon alone (monotherapy) or interferon plus 1000-1200 mg daily of ribavirin (combination therapy). At the end of the induction phase, 23 (56%) subjects had cleared HCV-RNA. During therapy, breakthrough w…
Numerical relations and skill level constrain co-adaptive behaviors of agents in sports teams.
2014
Similar to other complex systems in nature (e.g., a hunting pack, flocks of birds), sports teams have been modeled as social neurobiological systems in which interpersonal coordination tendencies of agents underpin team swarming behaviors. Swarming is seen as the result of agent co-adaptation to ecological constraints of performance environments by collectively perceiving specific possibilities for action (affordances for self and shared affordances). A major principle of invasion team sports assumed to promote effective performance is to outnumber the opposition (creation of numerical overloads) during different performance phases (attack and defense) in spatial regions adjacent to the bal…
Perception of Coaching Behaviors, Coping, and Achievement in a Sport Competition
2011
This study examined the relationship between perceived coaching behaviors, coping strategies during a sport competition, and sport achievement. A prospective design was used in which 80 athletes from individual sports completed measures of perceived coaching behaviors two days before a competition (Time 1) and measures of coping and sport achievement within three hours after a sport competition (Time 2). As expected, results of multiple regressions indicated that supportive coaching was a positive predictor of task-oriented coping and sport achievement whereas unsupportive coaching was a positive predictor of disengagement-oriented coping. Both types of coping were significantly associated …
Does being a Stranger make it Difficult to Cooperate?
2017
AbstractCompetition and cooperation are two somewhat opposed strategies for interpersonal social interaction that help us to achieve both individual and shared goals. The main aim of this study was to explore which type of social interaction (cooperative or competitive) is more stressful in a face-to-face same-sex dyad in healthy young participants (n = 178), considering outcome obtained in these tasks (positive or negative) and sex as moderating variables, and performance of the task alone as a control condition. Salivary cortisol (Csal) was measured in one sample obtained before task and four obtained after the task (+0, +15, +30 and +45 minutes after). Anxiety-state was assessed before a…
Nurses´ stressors and psychological distress during the COVID‐19 pandemic: The mediating role of coping and resilience
2021
This study analyses the cross-sectional effect of sources of stress during the peak of COVID-19 pandemic on nurses´ psychological distress, focusing on the mediating role of coping strategies, both problem focused and emotion focused and resilience.Cross-sectional and quantitative analyses.Structural equation modelling was performed using survey data obtained during the period between 1 April-25 May 2020 in a sample of 421 nurses from 39 Spanish provinces.Results confirmed that: (a) All the stressors have a significant, direct, and negative relationship with nurses´ psychological distress; (b) Emotion-focused strategies is negatively related to nurses´ psychological distress directly and in…
Influenza vaccination of primary healthcare physicians may be associated with vaccination in their patients: a vaccination coverage study
2015
Background: To assess the contribution of physician-related factors, especially their influenza vaccine status, in the vaccination coverage of their patients. Methods: A study of vaccination coverage was carried out in Spain in 2011–12. The dependent variable (vaccination coverage in patients aged ≥65 years) was obtained from regional records. Information was gathered on the vaccination of physicians through an anonymous web survey. We compared the vaccination coverage of patients with the vaccination of their physicians using the Student t test. Associations were determined using a multilevel regression model. Results: The coverage in patients aged ≥ 65 years was 56.3% and was higher (57.3…
Is There a Direct Link between Sexual Satisfaction and Restrictions during the Second Wave of the COVID-19 Pandemic?
2022
Background: Research suggested that the COVID-19 pandemic-related restrictions decreased sexual function and satisfaction. The present study examines the direct relationship between sexual satisfaction and restrictions during the second wave of the COVID-19 pandemic. Methods: A cross-sectional study was performed in Poland between 3 September 2020 and 18 January 2021. A convenience sample of 1364 adults, aged 18–67 (M = 25.13, SD = 6.45), among whom 62.39% were women, and 23.17% were single, completed anonymous web-based survey. The Sexual Satisfaction Questionnaire (SSQ) and Stringency Index (IS) were used to assess sexual satisfaction and the level of restrictions during the pandemic, res…
Biodosimetry Based on γ-H2AX Quantification and Cytogenetics after Partial- and Total-Body Irradiation during Fractionated Radiotherapy
2015
The aim of this current study was to quantitatively describe radiation-induced DNA damage and its distribution in leukocytes of cancer patients after fractionated partial- or total-body radiotherapy. Specifically, the impact of exposed anatomic region and administered dose was investigated in breast and prostate cancer patients receiving partial-body radiotherapy. DNA double-strand breaks (DSBs) were quantified by γ-H2AX immunostaining. The frequency of unstable chromosomal aberrations in stimulated lymphocytes was also determined and compared with the frequency of DNA DSBs in the same samples. The frequency of radiation-induced DNA damage was converted into dose, using ex vivo generated ca…
