To establish levels of association between physical fitness and match activity profiles of players in the Australian Football League (AFL) participation pathway. Players (N = 287, range 10.9-19.1 y) were assessed on 20-m sprint, AFL agility, vertical jump and running vertical jump, 20-m multistage fitness test (MSFT), and Athletic Abilities Assessment. Match activity profiles were obtained from global positioning system measures: relative speed, maximal velocity, and relative high-speed running. Correlational analyses revealed moderate relationships between sprint ( = .32-.57, ≤ .05) and jump test scores ( = .34-.78, ≤ .05) and match activity profiles in Local U12, Local U14, National U16, and National U18s, except jump tests in National U18s. AFL agility was also moderate to strongly associated in Local U12, Local U14, Local U18, and National U16s ( = .37-.87, ≤ .05) and strongly associated with relative speed in Local U18s ( = .84, ≤ .05). Match relative speed and high-speed running were moderate to strongly associated with 20-m MSFT in Local U14, Local U18, and National U18s ( = .41-.95, ≤ .05) and Athletic Abilities Assessment in Local U12 and Local U18s ( = .35-.67, ≤ .05). Match activity profile demands increased between Local U12 and National U16s, then plateaued. Physical fitness relates more strongly to match activity profiles in younger adolescent and national-level players. Recruiters should consider adolescent physical fitness and match activity profiles as dynamic across the AFL participation pathway.

Background: Changes in cardiac function and structure as well as their association with the cardiac autonomic nervous system remain incompletely characterized in children with stage 5 chronic kidney disease (CKD) receiving hemodialysis (HD).
Methods: A prospective observational cohort study was conducted on 40 Egyptian children with CKD on regular HD compared to 40 age- and sex-matched healthy children. All participants underwent thorough clinical examination, laboratory investigations, 24-h Holter monitoring, and 2D/4D echocardiographic study (conventional and advanced modalities).

Vitiligo is a pigmentary disorder acquired and caused by the loss or destruction of melanocytes from the epidermis. There is strong proof that vitiligo is mainly an autoimmune disease. Cathelicidin (LL37), an antimicrobial polypeptide, is an important part of the innate immune system and has a role in different skin autoimmune diseases.

Objective: To compare the clinical outcomes, including pregnancy rate, live birth rate, and miscarriage rate between vaginal progesterone Cyclogest suppository and Crinone vaginal progesterone gel as LPS in frozen-thawed embryo transfer in Intra-Cytoplasmic Sperm Injection (ICSI) cycles.
Methods: In this comparative retrospective chart review, 283 women who had frozen-thawed embryo transfer were assessed. The patients were divided into two groups based on the route of progesterone administration used as LPS.

Although the pathophysiology of migraine involves a complex ensemble of peripheral and central nervous system changes that remain incompletely understood, the activation and sensitization of the trigeminovascular system is believed to play a major role. However, non-invasive, in vivo neuroimaging studies investigating the underlying neural mechanisms of trigeminal system abnormalities in human migraine patients are limited. Here, we studied 60 patients with migraine (55 females, mean age ± SD: 36.
