ABSTRACT

BACKGROUND: We tested the hypothesis that Whole Body Vibration (WBV) positively affects the fatigue process ensuing from repeated bouts of maximal efforts, as induced by repeated sprints ability (RSA). Eleven male soccer players performed three sets of six repeated shuttle sprints (40 metres).

METHODS: Eleven male soccer players (age 23,6±4,5 years) were cross-randomized to perform WBW before RSA and during the recovery between sets (WBV-with) or to warm-up and passive recovery between sets (WBV-without). The effects of WBV were quantified by sprint time (ST) and blood lactate concentration (LA), collected up to 15th min after completion of tests.

RESULTS: ST during RSA showed a better maintenance of performance in the WBV-with compared to WBV-without condition in all three sets, reaching a statistical significance between-groups during the 2nd and 3rd set (P< 0.05). No significant differences in ST over the sets were detected in WBVwith, whereas a significant decrease was observed in the WBV-without condition (P<0.001). LA recovered significantly faster from the 9th to 15th minute of recovery in WBV-with as compared to WBV-without (P<0.05).

CONCLUSIONS: These findings would indicate that WBV performed during recovery between RSA sets is capable of delaying the onset of muscle fatigue resulting in a better maintenance of sprint performance.

ABSTRACT

BACKGROUND: The purpose of this study was to measure and compare jump load and dynamic performance in elite volleyball athletes under varied conditions over an entire season of practices and games. Jump load and dynamic performance were compared among (i) best jump height, (ii) mean jump height, as well as according to (iii) the number of jumps per game or practice session and (iv) the proportion of jumps higher than 50 cm relative to the total number of jumps in a practice or game.

METHODS: Every jump performed by each of 12 players, in all practices and regular games (813 player-sessions in total), was measured by a particle accelerometer in accordance with a validated protocol (Vert®). Data were collected and analysed using STATA; the significance level for definition of confidence intervals was set to 95%, unless otherwise specified. Statistical analysis and comparison of means and proportions between groups was based on standard t-tests.

RESULTS: Among player positions, the Middle Blocker consistently presented the greatest jump loads during the season; by comparison, the smallest jump loads were observed in the Setter.

CONCLUSIONS: Monitoring players’ jump loads and performance using a simple accelerometer provides evidence which can be used to plan individual player activity, roster composition, the season calendar and furthermore increase knowledge to reduce over-training and recurrence of injuries.

ABSTRACT

AIMS: Heart failure (HF) is common in both men and women, yet disease pathophysiology, presentation, and progression differ between sexes. Studies addressing whether biomarkers predict new onset HF sex-specifically are scarce. This study therefore aims to test the sex-specificity of 252 protein biomarkers for new-onset HF.

METHODS AND RESULTS: A matched case-control design in patients selected from cohorts within the HOMAGE consortium was used. Cases (new-onset HF, n = 562) and controls (n = 780) were matched for cohort (PREDICTOR, HEALTH-ABC, & PROSPER), follow-up time (defined as time from entry to incident HF), and age. Incident HF was defined as first hospitalization for HF. Targeted plasma proteins (n = 252) were measured using Proximity Extension Assay technology from O-link. To look for sex differences for new onset HF, we adjusted for cohort, age, and baseline clinical parameters. At baseline, women had a biomarker profile reflecting activated metabolism and immune responses. However, none of the biomarkers had a significant interaction with sex in predicting new onset HF, but four biomarkers had a trend towards sex-specificity (P < 0.013). E-selectin and interleukin 1 receptor antagonist were more female-specific, whereas IL17A and CHIT1 tended to be male sex-specific for incident HF.

CONCLUSIONS: The majority of biomarkers associated with incident HF did not significantly differ between women and men, despite clear differences in biomarkers at baseline.

ABSTRACT

BACKGROUND: Fetal growth restriction (FGR) is associated with a high fetal brain volume/liver volume (FBV/FLV) ratio. Ultrasound may not always be reliable, which has prompted further investigation of MRI techniques.

PURPOSE: To determine the relationship between FBV/FLV ratio, as measured by MRI, and gestational age (GA) in normal fetuses and those with FGR.

STUDY TYPE: Retrospective.

POPULATION: One hundred and forty seven singleton pregnancies including 105 appropriate-for-gestational age (AGA) fetuses and 42 FGR fetuses.

FIELD STRENGTH/SEQUENCE: Three-dimensional fast imaging employing steady-state acquisition at 1.5 T.

ASSESSMENT: The FBV and FLV were measured by three radiologists. The inter- and intraobserver agreements, the correlation between FBV/FLV ratio, and advancing GA were evaluated; the diagnostic value of FBV/FLV ratio was evaluated and compared with head circumference/abdominal circumference (HC/AC) ratio measured by ultrasound.

STATISTICAL TESTS: Intraclass correlation coefficient (ICC) was used to determine inter- and intraobserver agreements. Regression analysis was used to assess the correlation between FBV/FLV ratio and advancing GA. The diagnostic value of the FBV/FLV ratio was examined by the area under the receiver operating characteristic (ROC) curve.

RESULTS: The inter- and intraobserver agreements were excellent with an interobserver ICC of 0.984 and intra-observer ICCs of 0.989, 0.994, and 0.995. The FBV/FLV ratio in AGA fetuses decreased significantly with advancing GA (Pearson correlation coefficient = -0.844). The FBV/FLV ratio in FGR fetuses was significantly higher than that in AGA fetuses. To identify fetuses at high risk for FGR using the FBV/FLV ratio, the area under the ROC curve was 0.978, with an optimal cut-off value of 4.10. The sensitivity of FBV/FLV ratio in identifying FGR was significantly higher than that of HC/AC ratio (0.929 vs. 0.529).

DATA CONCLUSION: An inverse correlation exists between FBV/FLV ratio and advancing GA in normal fetuses. A high FBV/FLV ratio may be used to ascertain fetuses at high risk for FGR.

LEVEL OF EVIDENCE: 3 Technical Efficacy Stage: 3.

ABSTRACT

OBJECTIVE: The increasing complexity of clinical trial protocols and the very nature of investigational drugs increase the likelihood of prescribing errors and require comprehensive control and monitoring of treatments. The aim of this study was to measure and analyze the potential risks of prescribing errors in investigational drugs.

METHODS: A prospective, descriptive, and observational study was carried out in a third-level hospital in Madrid, for one month in 2017. Manual prescribing errors (EP) in investigational drugs and potential risks of harm to the patient were analyzed. A descriptive statistical analysis was performed, including the absolute and relative frequency for the variables.

RESULTS: A total of 254 medical orders corresponding to 327 lines of treatment and 274 different drugs were reviewed, of which 83% were categorized as “high-risk”. Results showed 217 (85.4%) EP within the identification of the medical order and 1,045 (319,6%) in the treatment. The risk level of harm to the patient was high for all EP in patient identification and moderate for all EP in the clinical trial identification. The lines of treatment showed an especially high-risk potential for EP in dosage (25%) and frequency (41%).

CONCLUSIONS: The high rate of EP found, along with the high-risk potential these entail, reflects the need for improving the security process when prescribing investigational drugs in our field.

ABSTRACT

OBJECTIVE: The aim: To analyze and calculate CVR in patients with T2DM and concomitant obesity.

PATIENTS AND METHODS: Materials and methods: The selection of patients was carried out based on the Uzhhorod District Clinical Hospital, in the period from November 2016 to January 2020. All patients were divided into 3 groups: 1 (n=93) with T2DM and concomitant obesity, 2 (n=87) with T2DM, 3 (n=39) with obesity. The treatment period lasted 1 year and included dosed exercise for at least 30 minutes per day and dietary recommendations. Patients in groups 1 and 2 received metformin 850 mg twice daily in combination with dapagliflozin 10 mg once daily. CVR was determined at the time of enrollment and after 1 year of treatment using: American College of Cardiology / American Heart Association Guideline on the Assessment of Cardiovascular Risk (2013) (ASCVD Risk) and Framingham Risk Score (FRS).

RESULTS: Results: The data obtained as a result of the study revealed the highest CVR in patients of group 1, in contrast to group 2 and 3 (p<0.05). After 1 year of complex treatment, CVR indicators were statistically significantly reduced in all experimental groups (p<0.05).

CONCLUSION: Conclusions: Determining CVR parameters and exposure to them within 10 years can remove unwanted cardiovascular complications.

ABSTRACT

OBJECTIVE: The aim: To study the effect of arterial hypertension on the course of chronic obstructive pulmonary disease in patients with comorbid pathology.

PATIENTS AND METHODS: Materials and methods: The prospective study included 61 patients with COPD: 32 stable male patients with COPD with comorbid arterial hypertension of stage II 1-3 degrees and 29 stable outpatients of men with COPD of clinical groups A-D with impaired respiratory function II-IV according to GOLD. All patients, in accordance with the goals and objectives of the study, were divided into 2 groups: group I consisted of men with isolated COPD, middle age – 56.0 (8.5) years, average duration of the disease – 16.2 (1.3) years, Group II consisted of male patients with COPD and arterial hypertension (AH), middle age – 59.5 (7.5). The patients underwent a general clinical examination, which included an assessment of complaints, anamnestic data, and a physical examination. The severity of COPD was determined on the basis of the frequency of exacerbations during the year, assessment of dyspnea using the mMRS scale, spirographic data. Statistical materials were processed using the STATISTICA 10.0 program.

RESULTS: Results: In group I, 20 patients (69%) complained of dyspnea during exercise, in group II – 25 patients (78%) (p = 0.4), 28 patients (96.5%) complained of cough with vague sputum. group and 30 patients in group II (93.8%) (p = 0.09). When assessing the number of exacerbations over the past year, it was determined that patients with isolated COPD had an average of 1.0 (1.0; 2.0) exacerbations, and patients with COPD and AH – 2.0 (1.0; 3.0 ) (p = 0.06). According to the CAT questionnaire, the following data were obtained: in group I – 9.0 (8.0; 11.0) points, and in group II – 17.5 (10.0; 20.0) points (p = 0.02). When conducting spirographic studies, a statistically significant more expressive bronchial obstruction was found in patients with COPD and comorbid hypertension.

CONCLUSION: Conclusions: The presence of comorbid arterial hypertension leads to the intermittent effect of diseases: according to the results of mMRC and SAT test, ailments for COPD were examined, they have a more severe course of underlying seizure in the presence of concomitant arterial hypertension. Clinical manifestations in patients with COPD and H are more severe compared to clinical manifestations in patients without aggravated diseases of the cardiovascular system. Concomitant arterial hypertension enhances the manifestations of bronchial obstruction, in the same way as with patients with isolated COPD.
