Abstract
Loturco, I, Pereira, LA, Mercer, VP, Oliveira, LP, Zanetti, V, Lima, L, Bastos, T, Moura, TBMA, and McGuigan, MR. Jump squat vs. resisted sprint training programs applied to elite youth soccer players: effects on sprint and power-related performance. J Strength Cond Res XX(X): 000–000, 2024—This study examined the effectiveness of 2 different and widely used training programs on the sprint and power-related performance of youth soccer players. Two distinct training strategies—vertically oriented jump squats (JSs) or horizontally oriented resisted sprints (RSs)—were executed under the same absolute loading conditions (i.e., 30% of the athletes’ body mass [BM]) during a 4-week preseason period. Training schemes, loading intensities (based on %BM), and the number of experimental sessions were designed in conjunction with the soccer club’s coaching staff, considering the calendar, available resources, and regular training programs. Twenty-five under-17 soccer players performed a series of speed, power, and jump tests before and after 10 resisted training sessions, consisting solely of loaded JS or RS. Overall, neither group (i.e., JS or RS training groups) exhibited any improvement in linear sprint and change-of-direction (COD) speed. Conversely, vertical jumping ability and peak velocity in the loaded JS increased significantly only in the JS group, which may positively affect players’ performance and training prescription during short soccer preseasons. Given the challenges in enhancing sprint speed among soccer players during preseasons (and even over the competitive season), coupled with the limited effectiveness of RS in improving sprinting, COD, and jumping capabilities within congested and short training phases (i.e., ≤4 weeks), the regular use of RS training methods during these phases may be highly questionable. Coaches should carefully consider these critical limitations and potential disadvantages when designing neuromuscular training programs for soccer players during the preparatory phases of the annual training season.

ABSTRACT
This systematic review aimed to analyze the evolution, reliability, and validity of agility testing in athletes. The results indicated the necessity of prioritizing reactive agility (RA) as the primary focus in the scientific assessment of athletes' agility performance. The cutting and “stop and go” tests were the most widely used agility tests, utilizing light or human random signals as stimuli. Overall, the agility tests demonstrated that high reliability and poor agility performance could be predictive indicators of higher sports injury rates. Convergent validity between the agility and change of direction speed (CODS) tests was moderate. Agility tests could also differentiate athletes with different performance levels and age groups. Future practitioners should focus on customizing the “gold standard” agility tests for specific sports, which includes evaluating the reliability and validity of these tests.

Published: August 2024

Robust functional continuum regression (RFCR) is an innovation as a development of functional continuum regression that can be applied to functional data and is resistant to outliers. The resistance of RFCR depends on the applied weighting function. This study aims to evaluate the RFCR performance to handle outliers. We propose the various weighting functions in this evaluation, i.e., Huber, Hampel, Ramsay, and Tukey (Bisquare), which do not eliminate or give zero weight to observed data identified as outliers. This contribution is essential to determining the appropriate RFCR method without eliminating the outlier data. The result shows that the RFCR performance with the Huber weighting function is better than the others, based on the goodness of fit, consisting of the root means square error of prediction (RMSEP), the correlation between the actual data and the model, and the mean absolute error (MAE).Keywords: functional data analysis; Huber weighted function; Hampel weighted function; Ramsay weighted function; Tukey (Bisquare) weighted function.

Aim. To study the effectiveness of virtual reality (VR) relaxation to correct symptoms of depression, anxiety, emotional and cognitive disorders in patients with heart failure (HF).Material and methods. The study included 100 patients with HF aged 21 to 83 years. A main group of 58 people was randomly selected, each of whom received a course of 5 daily VR sessions of a relaxation program. Patients in the control group underwent VR sessions containing distracting visual images without a relaxation program. During the study, mental status of all patients was assessed using questionnaires sensitive to the cognitive and emotional areas.Results. After completing five daily VR sessions with a relaxation program, patients with HF noted a decrease in stress (p=0,031) and improved sleep (p=0,002), and 2 days after completing the VR course — improved well-being (p=0,006), mood (p=0,001), sleep (p=0,003) and decreased stress (p=0,005). In addition, patients in the main group had improved daily activities (p=0,004), pain/discomfort (p=0,007), anxiety/depression (p=0,016) and general well-being (p=0,009).Conclusion. VR relaxation is effective for reducing stress, improving mental status and cognitive functioning in patients with HF.

Aim. Comparative analysis of two groups of patients with non-ST elevation acute coronary syndrome (NSTE-ACS) in age subgroups 60-74 years (elderly patients) and 75 years and older (senile patients); comparison of the coronary angiography (CAG) performance rate with percutaneous coronary intervention (PCI) consideration and time to intervention; evaluation of comorbidities associated with PCI non-performance in clinical practice in the selected subgroups of patients.Material and methods. The study included 580 patients aged 60 years and older (60-74 years (elderly patient group) and 75 years and older (senile patient group)), hospitalized at the regional vascular center of City Clinical Hospital in Moscow during the period from January 01, 2021 to December 31, 2022 with the diagnosis of NSTE-ACS. The decision to perform CAG with possible PCI was made by hospital physicians in the routine order of daily clinical practice. Statistical analysis was performed in Microsoft Excel 19.Results. In the group of senile patients, there was a comparatively higher percentage of women, patients with a final diagnosis of myocardial infarction, prevalence of anemia, chronic and Killip class ≥II acute heart failure, atrial fibrillation, and stage ≥3 chronic kidney disease. CAG/PCI was performed in the elderly patient group in 91,5% of cases, which was more frequent compared to the senile patient group, where the intervention was performed in 85% of cases (p=0,015). Mostly, CAG/PCI in both groups was performed within the first day of hospital admission. Anemia was significantly more common in patients aged 60-74 years in the conservative strategy groups, and aortic stenosis was more common in those aged 75 years and older. In any age group with non-performance of CAG/PCI, a significant frequency of in-hospital mortality was observed.Conclusion. Patients with NSTE-ACS of elderly and senile age included in the study predominantly underwent invasive treatment within the first day of hospitalization. The elderly and senile age patient groups differed in the prevalence of revascularization, comorbidities and in-hospital outcomes, and did not differ in the time and treatment strategy. The subgroups with interventional treatment more often had a favorable in-hospital outcome.

Aim. To characterize the association between cardiovascular risk factors and clinical and paraclinical variables with the severity of concomitant carotid and subclavian atherosclerosis in patients with acute coronary syndrome (ACS).Material and methods. Patients with ACS of any type, having obstructive coronary artery disease (CAD) confirmed by coronary angiography, underwent an ultrasound of the carotid and subclavian arteries with quantitative plaque assessment. The most important clinical, echocardiographic, angiographic and laboratory variables that contribute to atherosclerosis and/or affect the cardiovascular prognosis were evaluated. In patients with ACS considered ad the CAD onset, retrospective calculation of Systematic Coronary Risk Evaluation2 (SCORE2) score was performed.Results. A total of 312 patients aged 64 (56, 72) years (male, 69,2%) were studied. The detection rate of carotid/subclavian plaque was 86% and was higher in patients with more severe CAD — 79,4, 87,0, 92,6% in patients with 1-, 2- and 3-vessel disease respectively (p=0,027). However, 20% of patients with 2-/3-vessel CAD had no carotid/ subclavian atherosclerosis. Most of the traditional cardiovascular risk factors and other studied echocardiographic, angiographic, laboratory variables, as well as SCORE2 in patients with CAD onset did not demonstrate independent association with the severity of carotid/ subclavian atherosclerosis. The variability of the total plaque area (TPA) was explained by related multifactor regression model only to a small extent, R2=13%. Age (β 0,76, 95% CI 0,24-1,29, p=0,004), glomerular filtration rate (β -0,44, 95% CI -0,76 — -0,13, p=0,006); peripheral artery disease (β 19,50, 95% CI 1,63-37,37, p=0,033) demonstrated a significant independent association with TPA.Conclusion. In patients with ACS, only age, glomerular filtration rate and history of peripheral artery disease demonstrated the independent associations with carotid/subclavian atherosclerotic burden. Assessed variables explained 13% of TPA variability.

Aim. To investigate the association of 10 circulating plasma microRNAs with collateral flow degree in chronic total occlusion (CTO) patients with coronary artery disease (CAD).Materials and methods. Plasma expression levels of 10 circulating miRNAs were measured by real-time PCR using Taqman technology in a sample of 43 subjects. The study included patients with CAD and CTO with good (n=13) or poor (n=10) coronary collateral circulation (CCC) based on Rentrop classification and a control group of patients without significant coronary stenosis (n=20).Results. Significant differences in expression levels were found for 7 circulating miRNAs in patients with CTO and good CCC and for 5 microRNAs in the combined group of patients with CTO compared to the control group. Among the 7 microRNAs, decreased expression of hsa-miR-126-5p, hsa-miR-146a-5p, hsa-miR-155-5p, hsa-miR-15b-5p, hsa-miR-21-5p, hsa-miR-23a-3p and increased expression of hsa-miR-451a were detected. For the first time, we showed that the level of 2 microRNAs (hsa-miR-23a-3p, hsa-miR-21-5p) is significantly reduced and the level of hsa-miR-451a is increased in patients with CAD with good CCC.Conclusion. Plasma microRNAs with significant differences obtained can be used for further studies on a larger sample size as candidate biomarkers for assessing the severity of ССС in the presence of CTO.

: Poly Cystic Ovarian Disease is a common endocrine disorder which is difficult to define because there is no single abnormality or diagnostic test that defines the syndrome. But different studies on PCOD shows the life style changes, food pattern and several other factors were involved in the development of PCOD. It is very important for women to take care of their health during their reproductive years because much reproductive health related problems can arise during this period. So it is important to know the risk factors of PCOD, to reduce the morbidity level.A case control study was carried out in hospital and in community. Three groups were selected: hospital cases, hospital controls and community controls with 50 samples in each group selected by purposive sampling technique. The data was collected using semi structured questionnaire using interview method. Approximately 10- 15 mins was taken by the study participants to answer the questions. By using Odds ratio the risk factors for PCOD were found out. The risk factors identifiedwere medical history of other than PCOD (OR= 25.242), regular periods (OR=0.027), number of child (OR=7.667), taking milk (OR= 0.288) among hospital cases and hospital controls. Among hospital cases and community controls education (OR=5.167), BMI (OR= 4.25), Marital status (OR= 6), number of children (OR=40.773), taking tea (OR= 0.278), not doing exercise (OR= 0.255) were the risk factors identified. From the findings, it is evident that women with no children are 41 times at higher risk of getting PCOD when compared with women having children.The study concludes that risk factors can be identified for PCOD. This will assist the community health nurse to take up preventive measures to bring down the morbidity rate.
Impact of telehealth on pediatric asthma management during the COVID-19 pandemic
Authors: Kannepalli Venkata Srilakshmi 
Published: August 2024

The COVID-19 pandemic has pushed for telehealth services at an unprecedentedly rapid pace, thereby providing a golden opportunity to test the fruits of telehealth service delivery within the context of chronic care, such as pediatric asthma management. This paper therefore takes a broader view and places much emphasis on the role-triangulation that might be played by telehealth in comparison with in-person visits in the management of pediatric asthma. A retrospective cohort study design was used to collect data for 250 pediatric asthma patients. Of these, 125 underwent telehealth consultations, while the remaining 125 did so in person. Metrics obtained for analysis were the frequency of asthma exacerbations, emergency visits, hospitalizations, medication adherence, and patient/parent satisfaction. The team of researchers observed that there was a significant reduction in emergency visits to the department and hospitalizations in the telehealth group. The adherence to medication was also comparable, it so happened, which resulted in very encouraging satisfaction levels for the patients and parents. However, a few issues were noticed, such as access to technology, and in the sphere of communication, there were a few glitches.: The practice of telehealth is a feasible and effective strategy for the management of pediatric asthma. This setting allows convenience with decreased infection rates. However, technological barriers need to be addressed if the diffusion is to broaden across the population and equal opportunities for access to remote health care are to be created. Introduction

Abstract

Background: Neck postures can affect cervical intradiscal pressure (CIDP) and contribute to intervertebral disc (IVD) pathologies. Despite neck flexion and protraction posture prevalence and potential impact on cervical IVD health, no studies have investigated CIDP during end-range protraction and retraction. This study investigated (1) CIDP differences between cervical traction, six sagittal plane cervical end-ranges, and neutral posture; (2) CIDP and segmental cervical range of motion (ROM) correlation; and (3) CIDP measurement reliability.
Methods: Seven cadaveric specimens, mean age 80.6±7.2 years, had cervical segmental ROM assessed by lateral radiographs and CIDP responses measured by fiberoptic pressure sensors in C4-5, C5-6, and C6-7 IVDs for supine end-range chin to neck, chin to sternum, protraction-flexion, occiput to neck, occiput to thorax, retraction-extension, and neutral traction.
Results: Friedman tests revealed greater CIDP in (1) chin to sternum as compared to traction at C4-5, C5-6 and C6-7 (p<.02); (2) chin to sternum as compared to retraction-extension at C5-6 and C6-7 (p=.027); and (3) chin to sternum as compared to protraction-flexion at C5-6 (p=.042). End-range postures demonstrated moderate effect sizes on CIDP at C4-5 (ES=.31), C5-6 (ES=.46), and C6-7 (ES=.36) using Kendall’s W. Strong correlations between cervical segmental ROM and CIDP were identified at C4-5 chin to neck, rS=.79, p=.04; C5-6 occiput to thorax, rS=.79, p=.04; and C6-7 protraction-flexion, rS=.82, p=.02. Reliability was good to excellent for CIDP and segmental ROM measurements (ICC>.92, 95%CI .86-.98).
Conclusions: Consistent chin to sternum increases and traction decreases in CIDP occurred at all cervical IVD levels. The CIDP tended to increase during flexion end-ranges at all IVD levels, while extension, protraction, and retraction tended to decrease at C5-6, C6-7 and increase at C4-5. Large positive or negative CIDP variations with even larger standard deviations were observed within and between cervical IVD segments during various postures.
