Quantifying the effects of four weeks of low-volume high-intensity sprint interval training on V ̇O2max through assessment of hemodynamics.
CONCLUSIONS: V̇O2max is a function of maximal cardiac output and a-vO2dif-max, so for a meaningful change to occur in cardiorespiratory fitness, there must be a concomitant increase in O2 delivery. This study demonstrates that a low volume SIT intervention evokes peripherally mediated responses (a-vO2dif) and anaerobic substrate utilization rather than O2 delivery components. Future works should address the time course of the responses and when assessing V̇O2max-based responses that due attention be given to the hemodynamic responses as means of quantification of the response.

A Retrieved Sparganum of Spirometra erinaceieuropaei from a Korean Man during Mechanical Thrombectomy.
We report a case of cerebral intravascular sparganosis in an elderly patient with acute ischemic stroke who was diagnosed by retrieving sparganum during mechanical thrombectomy. Finally, the parasites were identified as Spirometra erinaceieuropaei using multiplex PCR and cox1 gene sequencing. PMID: 32615744 [PubMed - in process]

Cardiovascular comorbidities based on impaired pulmonary function in non-smoking population
Conclusion: The prevalence of cardiovascular comorbidities in non-smokers was higher in restrictive group and COPD, compared to normal control. Restrictive group was independently associated with coronary artery disease in non-smokers.

Comparative study of cardiorespiratory adaptations in elite basketball players of different age groups.
CONCLUSIONS: The increased LVM is attributed to concentric hypertrophy. This is further supported by the finding that there was no relationship between V̇ O2max and echo parameters. The results of the present study indicate that the cardiorespiratory adaptations caused by basketball training are mainly formed in the early age stages without further increase throughout the years of action.

Decreased exercise capacity in young athletes using self-adapted mouthguards
ConclusionUse of a self-adapted mouthguard led to increased metabolic effort and a significant reduction in ventilation parameters. Unchanged oxygen uptake may be the result of cardiopulmonary compensation and increased breathing efforts, which slightly affects performance. These results and the obvious preventive effects of mouthguards support their use in sports.

Reduced Forced Vital Capacity and the Number of Chest Wall Surgeries are Associated with Decreased Exercise Capacity in Children with Congenital Heart Disease
AbstractLow forced vital capacity (FVC) is associated with decreased exercise capacity in CHD. Multiple prior cardiac surgeries have been associated with low FVC. We seek to understand the relationship between low FVC, number of cardiac surgeries and cardiopulmonary response leading to decreased exercise capacity. Retrospective chart review of demographics, surgical history and exercise testing including spirometry was performed in patients with CHD. Single ventricle patients were excluded. Low FVC was defined as a Z-score below the lower limit of normal. Exercise parameters were expressed as a percent of predicted. There ...

Incremental prognostic value of arterial elastance in mild-to-moderate idiopathic pulmonary fibrosis
AbstractPrevious reports suggested that poor pulmonary function was associated with increased arterial elastance (Ea) in patients with chronic obstructive pulmonary disease and systemic sclerosis. The mechanisms connecting pulmonary function and Ea have not yet been accurately studied in patients with idiopathic pulmonary fibrosis (IPF). The present study was designed to assess Ea in IPF patients without chronic severe pulmonary hypertension and to determine its prognostic role over a medium-term follow-up. This retrospective study included 60 consecutive patients with mild-to-moderate IPF (73.8  ± 6.6 years, 75% mal...

Cardiovascular response to exercise in preterm-born children with and without low lung function
Conclusions: Despite being at risk of reduced exercise tolerance, preterm-born children with low lung function show comparable cardiovascular response to exercise to preterm-born and term-born controls.
