Quantifying training intensity distribution in a group of Norwegian professional soccer players.
2011
Purpose:This study was designed to quantify the daily distribution of training intensity in a group of professional soccer players in Norway based on three different methods of training intensity quantification.Methods:Fifteen male athletes (age, 24 ± 5 y) performed treadmill test to exhaustion to determine heart rate and VO2 corresponding to ventilatory thresholds (VT1, VT2), maximal oxygen consumption (VO2max) and maximal heart rate. VT1 and VT2 were used to delineate three intensity zones based on heart rate. During a 4 wk period in the preseason (N = 15), and two separate weeks late in the season (N = 11), all endurance and on-ball training sessions (preseason: N = 378, season: N= 78) w…
Changes in microflora in dental plaque from cancer patients undergoing chemotherapy and the relationship of these changes with mucositis: a pilot stu…
2015
Background: To assess changes in oral microflora in dental plaque from cancer patients within 7 days of the first course of chemotherapy, and the relationship of the changes with mucositis. Material and Methods: Thirty cancer patients, divided into a test group undergoing chemotherapy and a control group no undergoing chemotherapy, were enrolled in this pilot study. Oral microflora were cultured from three samples of dental plaque at t0 (before chemotherapy), t1 (1 day after chemotherapy) and t2 (7 days after chemotherapy). Single and crossed descriptive analyses were used to establish prevalence, and the χ 2 test was used to establish the statistical significance of the differences observe…
Burkitt lymphoma associated with human immunodeficiency virus infection and pulmonary tuberculosis: A case report.
2019
Abstract Introduction: The association of human immunodeficiency virus (HIV) infection with Burkitt lymphoma is related to the presence of Epstein Barr virus infection and the impact of the HIV antigen on the expansion of B-polyclonal cells. In Southeast Europe, the association is rare, and recognizing this is important in the therapeutic decision to increase patient survival rate. The association of HIV with Burkitt lymphoma and tuberculosis is even more rarely described in the literature. Patient concerns: We present the case of a 40-year-old patient who presented with a 3-week history of fever (max. 38.7 °C), painful axillary swelling on the right side, lumbar pain, gait disorders, heada…
Tumor Volume, CT Scan, Lymphography, Sonography, Intravenous Pyelography, and Tumor Markers in Testis Tumors
1989
Correlation of tumor volume to tumor stage in 134 patients with nonseminomatous testicular tumors, which were classified according to the TNM system, revealed similar tumor load for N0 and N1 patients. CT scans (n = 92), lymphangiography (n = 47), intravenous pyelography (IVP) (n = 134), sonography (n = 118) and serial tumor markers (n = 82) were evaluated for sensitivity, specificity and accuracy, both separately and in different combinations. The best individual results were obtained by lymphangiography (sensitivity 0.77, specificity 0.73, accuracy 0.75) and CT scan (sensitivity 0.52, specificity 0.91, accuracy 0.70). In combination CT scan and lymphangiography were the most valuable diag…
Neuromuscular fatigue and recovery in maximal compared to explosive strength loading.
1997
The purpose of this study was to examine acute neuromuscular fatigue and its recovery in men (n = 8) and women (n = 8). Two strenuous, but clearly different exercises were compared: maximal (MSL) versus explosive strength loading (ESL). The MSL included five sets of ten repetition maximum bilateral leg extensions. The same task and the same number of sets was performed in ESL but with 40% from the load used in MSL and performed as explosively as possible. Isometric force-time curves were measured during maximal voluntary bilateral isometric action of the leg extensors before the fatigue loading and after each set. The measurements were repeated after resting for 1 h, 2 h, 1 day and two days…
A decision tree to help determine the best timing and antiretroviral strategy in HIV-infected patients.
2011
SUMMARYOptimal antiretroviral strategies for HIV-infected patients still need to be established. To this end a decision tree including different antiretroviral strategies that could be adopted for HIV-infected patients was built. A 10-year follow-up was simulated by using transitional probabilities estimated from a large cohort using a time-homogeneous Markov model. The desired outcome was for patients to maintain a CD4 cell count of >500 cells/mm3without experiencing AIDS or death. For patients with a baseline HIV viral load ⩾5 log10copies/ml, boosted protease inhibitor-based immediate highly active antiretroviral therapy (HAART) allowed them to spend 12% more time with CD4 ⩾500/mm3than…
Nursing Workload, Knowledge about Pain, and Their Relation to Pain Records
2020
To study the relationship between frequency of pain assessment and nursing workload, and also to analyze the frequency of pain assessment and its relation to knowledge and attitudes toward pain on nursing professionals in intensive care unit.An ambispective study was conducted in a Spanish tertiary-level intensive care unit between October 2017 and April 2018. For measurement of workload, the Nursing Activities Score scale was used, and for measurement of pain knowledge, the Knowledge and Attitudes Survey Regarding Pain was used.There were 1,207 measurements among 41 nurses and 1,838 among 317 patients. The average nursing workload was high (70.97 points). We found statistically significant…
Standardized T2* map of normal human heart in vivo to correct T2* segmental artefacts.
2007
A segmental, multislice, multi-echo T2* MRI approach could be useful in heart iron-overloaded patients to account for heterogeneous iron distribution, demonstrated by histological studies. However, segmental T2* assessment in heart can be affected by the presence of geometrical and susceptibility artefacts, which can act on different segments in different ways. The aim of this study was to assess T2* value distribution in the left ventricle and to develop a correction procedure to compensate for artefactual variations in segmental analysis. MRI was performed in four groups of 22 subjects each: healthy subjects (I), controls (II) (thalassemia intermedia patients without iron overload), thala…
Reduced right atrial contractile force in patients with left ventricular diastolic dysfunction: A study in human atrial fibers—contractile force and …
2017
Summary Background/Objective The aim of our study was to evaluate right heart contractile force in patients with diastolic dysfunction (DD) with preserved left heart ejection fraction undergoing cardiac surgery. We examined the contractile properties of skinned human fibers obtained from the right auricle in two groups (DD and controls). Methods Right atrial tissue from 64 patients, who were undergoing cardiac surgery, were collected before extracorporal circulation. Tissue was conserved and prepared as "skinned fibers". We exposed the dissected fibers to increasing calcium concentrations and recorded the force values. Results Patients with DD develop significantly less force at middle and …
