The main outcomes of interest were RVEDA, RV fractional area change (FAC), and RV outflow tract measurements. Generalized estimating equations with repeated measures were used to identify the association between preload reducing agents and echocardiographic structural progression.

Patients who received preload reducing agents (n = 6) were older and had larger RVs with lower FAC at baseline. However, treatment with preload reducing agents was associated with less RVEDA enlargement during mean 3.3 (range 1-6.7) years of treatment in multivariate analysis (% change in RVEDA associated with treatment -7.71; 95% confidence interval -13.29 to -2.13; P= .007).

Preload reducing agents show promising results in slowing RV enlargement in patients with ARVC and show possible disease-modifying potential.

This is largely determined by the proximodistal axis of growth. However, little is known about how proximal-distal growth is controlled to determine leaf shape. Here, we show that Arabidopsis leaf and sepal proximodistal growth is tuned by two phytohormones. Two class A AUXIN RESPONSE FACTORs (ARFs), ARF6 and ARF8, activate the transcription of DWARF4, which encodes a key brassinosteroid (BR) biosynthetic enzyme. At the cellular level, the phytohormones promote more directional cell expansion along the proximodistal axis, as well as final cell sizes. BRs promote the demethyl-esterification of cell wall pectins, leading to isotropic in-plane cell wall loosening. Notably, numerical simulation showed that isotropic cell wall loosening could lead to directional cell and organ growth along the proximodistal axis. Taken together, we show that auxin acts through biosynthesis of BRs to determine cell wall mechanics and directional cell growth to generate leaves of variable roundness.

It remains unclear whether studies comparing maximal oxygen uptake (VO

) response to sprint interval training (SIT) vs. find more moderate-intensity continuous training (MICT) are associated with a high risk of bias and poor reporting quality. The purpose of this study was to evaluate the risk of bias and quality of reporting in studies comparing changes in VO

between SIT and MICT.

We conducted a comprehensive literature search of 4 major databases AMED, CINAHL, EMBASE, and MEDLINE. Studies were excluded if participants were not healthy adult humans or if training protocols were unsupervised, lasted less than 2 weeks, or utilized mixed exercise modalities. We used the Cochrane Collaboration tool and the CONSORT checklist for non-pharmacological trials to evaluate the risk of bias and reporting quality, respectively.

Twenty-eight studies with 30 comparisons (3 studies included 2 SIT groups) were included in our meta-analysis (n = 360 SIT participants body mass index (BMI) = 25.9 ± 3.7 kg/m

, baseline VO

 = 37.9 ± 8.0 mL/kg/min; n = 359 MICT participants BMI = 25.5 ± 3.8 kg/m

 ; baseline VO

 = 38.3 ± 8.0 mL/kg/min; all mean ± SD). All studies had an unclear risk of bias and poor reporting quality.

Although we observed a lack of superiority between SIT and MICT for improving VO

(weighted Hedge's g = -0.004, 95% confidence interval (95%CI) -0.08 to 0.07), the overall unclear risk of bias calls the validity of this conclusion into question. Future studies using robust study designs are needed to interrogate the possibility that SIT and MICT result in similar changes in VO

.

Although we observed a lack of superiority between SIT and MICT for improving VO2max (weighted Hedge's g = -0.004, 95% confidence interval (95%CI) -0.08 to 0.07), the overall unclear risk of bias calls the validity of this conclusion into question. Future studies using robust study designs are needed to interrogate the possibility that SIT and MICT result in similar changes in VO2max.

We studied the association between different levels of physical activity (PA) and major cardiovascular disease (CVD) risk factors in adult people, as well as sex-specific differences.

Medical data from a large Spanish cohort of workers (aged 18-64 years) were prospectively obtained during a five-year period. Participants were categorized attending to their self-reported PA levels as inactive (performing neither moderate nor vigorous-intensity PA), or either regularly or insufficiently active (meeting or not, respectively, international recommendations of PA [≥ 150 or ≥ 75 min/week of moderate or vigorous-intensity PA, respectively, or a combination thereof]), and risk of diabetes, hypercholesterolemia, hypertension, and obesity was assessed.

Data from 527,662 participants (32% women) were used for analysis. 63.5, 12.3, and 24.2 % of the participants were inactive, insufficiently active, and regularly active, respectively. A significantly lower likelihood of all CVD risk factors was found in both regularly active (by 42 to 10%) and - although less remarkable - insufficiently active individuals (by 30 to 9%) vs their inactive referents. Although these results were overall corroborated in sex-specific analyses, a PA dose-dependent association was not observed for hypercholesterolemia in men and PA - whether insufficient or regular - conferred no significant protective effect against obesity in women.

Our findings suggest that PA reduces the odds of major CVD risk factors in a dose-response manner but there are some sex-specific differences.

Active videogames or exergames have been used as an innovative way to promote physical activity (PA) among various populations. A player's interest in active videogames is associated with the fun and entertaining nature of the games and may trigger situational interest, thus increasing engagement. The goal of this study was to examine the impact of situational interest dimensions on college students' PA when playing the design-based bike exergame Greedy Rabbit (Vescape, Berlin, Germany).

Sixty undergraduate students (age 20.8 ± 1.3 years, mean ± SD, 18-25 years old; 51.7% males) were recruited from the kinesiology department of a university located in the southern region of Belgium. The participants were assigned to an experimental group (n = 41) or a control group (n = 19) based on an incremental cycling test. Students in the experimental group engaged in 1 session of Greedy Rabbit while students in the control group engaged in 1 session of a placebo version of Greedy Rabbit. The length of the sessions ranged from 24 min to 31 min.
