s without emphysema, the tumor size in severe emphysema patients tends to be measured smaller in preoperative CT than the pathological specimen. • This trend is more evident when large tumors are measured on axial CT images alone.

Factors such as prone body position, hydrostatic pressure, and intermittent breath-holding subject aquatic athletes to unique physical and environmental stressors during swimming exercise. The relationship between exposure to aquatic exercise and both arterial stiffness and wave reflection properties is not well-understood. This study assessed central artery stiffness and wave reflection properties in elite pool-swimmers (SW), long-distance open-water swimmers (OW), and water polo players (WP) to examine the relationship between these variables and aquatic exercise.

Athletes competing in SW, OW and WP events at the FINA World Championships were recruited. Carotid-femoral pulse wave velocity, and pulse wave analysis were used to quantify arterial stiffness, and central wave reflection properties.

Athletes undertook differing amounts of weekly swimming distance in training according to their discipline (SW 40.2 ± 21.1km, OW 59.7 ± 28.4km, WP 11.4 ± 6.3km; all p < 0.05). Pulse wave velocity (Males [SW 6.0 ± 0.6m/s, OW 6.5 ± 0.8m/s, WP 6.7 ± 0.9m/s], Females [SW 5.4 ± 0.6m/s, OW 5.3 ± 0.5m/s, WP 5.2 ± 0.8m/s; p = 0.4]) was similar across disciplines for females but was greater in male WP compared to male SW (p = 0.005). Augmentation index (Males [SW -3.4 ± 11%, OW -9.6 ± 6.4%, WP 1.7 ± 10.9%], Females [SW 3.5 ± 13.5%, OW -13.2 ± 10.7%, WP -2.8 ± 10.7%]) was lower in male OW compared to WP (p = 0.03), and higher in female SW compared to OW (p = 0.002). Augmentation index normalized to a heart rate of 75bpm was inversely related to weekly swim distance in training (r = -0.27, p = 0.004).

This study provides evidence that the central vasculature of elite aquatic athletes differs by discipline, and this is associated with training load.

The cells were found to be rod-shaped and motile, growing in the form of creamy, convex and shiny colonies. The strain could grow in the presence of NaCl at concentrations 1-17% (w/v) (optimum, 3%), temperatures 10-40 °C (optimum, 30 °C) and pH 6.0-11.0 (optimum, pH 7.0) on marine agar. Strain TBZ9T 16S rRNA gene sequence was related to the genus Halomonas showing highest similarities to Halomonas arcis AJ282T (98.4%), Halomonas songnenensis NEAU-ST10-39T (98.0%) and Halomonas lutescens Q1UT (97.8%). In the phylogenetic trees, strain TBZ9T formed a distinct branch closely related to a subclade inside the Halomonas genus. Digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain TBZ9T and H. arcis AJ282T (20.0%, 74.0%) and H. songnenensis NEAU-ST10-39T (19.8%, 75.2%) indicated that TBZ9T represents a distinct species. Evaluation of fatty acid contents determined C100, C160, C120 3-OH, summed feature 3 (C161 ω7c and/or C161 ω6c) and summed feature 8 (C181 ω7c and/or C181 ω6c) as major cellular fatty acids. The major quinone of strain TBZ9T was Q-9. Polar lipid patterns consisted of phosphatidylglycerol (PG), phosphatidylethanolamine (PE), two unidentified phospholipids (PL) and four unidentified polar lipids (L). The average DNA G + C content of strain TBZ9T is 55.4 mol%. Results from phenotypic, chemotaxonomic and molecular analysis suggest that the strain TBZ9T represents a novel species within the genus Halomonas for which the name Halomonas azerica sp. read more nov. is proposed. The type strain is TBZ9T (= KACC 21783T = LMG 25775T).

This magnetic resonance imaging study examined the most frequent anatomical variants of the anterior communicating artery (ACoA) complex of the cerebral arterial circle, and aimed to determine whether they were associated with ACoA complex aneurysm.

The study enrolled 669 patients. Using three-dimensional time-of-flight magnetic resonance angiography, 617 patients were classified into the following groups based on the anatomical variation in the ACoA complex no ACoA complex anomaly; ACoA complex aneurysm; and vascular anomaly distant from the cerebral arterial circle.

Of the 617 classified subjects, the classical anatomical description applied to 48.73% in the no ACoA complex anomaly group and 37.5% in the ACoA complex aneurysm group. One variant (left anterior cerebral artery segment A1 hypoplasia) was significantly more frequent in the ACoA complex aneurysm group. There was no sex difference in the prevalence of any variant.

Anatomical variants of the ACoA complex of the cerebral arterial circle were found in almost half of the subjects. One variant seemed to be associated with a higher likelihood of an aneurysm, but causality could not be inferred.

To investigate the impact of the COVID-19 pandemic on caregivers of youth with type 1 diabetes.

We performed a qualitative research based on an open-ended questionnaire that was conducted through an online platform for primary caregivers of children and adolescents with type 1 diabetes. Participants were asked to describe the impact of the COVID-19 outbreak on their caring for youth with diabetes, as well as the emotional burden that it has brought to their personal lives. Interview responses were coded and stratified by youth age ≤ 12years (youth aged ≤ 12years) and between 13 and 18years (youth aged > 12years). The connections between the responses were identified based on either positive or negative content of the reported experience. Data were analyzed in accordance with an inductive reasoning methodology.

A total of 318 participants (mean age of 40.3 ± 8.1years old) were included, representing caregivers of youth aged 11.7 ± 4.3-year-old with diabetes duration of 5.1 ± 3.8years. The preponderance of negative feelings was noteworthy.
