IntroductionDue to the increase in participation and risk of anterior cruciate ligament (ACL) injuries and concussion in women’s Australian Football, an injury prevention programme (Prep-to-Play) was codesigned with consumers (eg, coaches, players) and stakeholders (eg, the Australian Football League). The impact of supported and unsupported interventions on the use of Prep-to-Play (primary aim) and injury rates (secondary aim) will be evaluated in women and girls playing community Australian Football.Methods and analysisThis stepped-wedge, cluster randomised controlled trial will include ≥140 teams from U16, U18 or senior women’s competitions. All 10 geographically separated clusters (each containing ≥14 teams) will start in the control (unsupported) phase and be randomised to one of five dates (or ‘wedges’) during the 2021 or 2022 season to sequentially transition to the intervention (supported Prep-to-Play), until all teams receive the intervention. Prep-to-Play includes four elements: a neuromuscular training warm-up, contact-focussed football skills (eg, tackling), strength exercises and education (eg, technique cues). When transitioning to supported interventions, study physiotherapists will deliver a workshop to coaches and player leaders on how to use Prep-to-Play, attend team training at least two times and provide ongoing support. In the unsupported phase, team will continue usual routines and may freely access available Prep-to-Play resources online (eg, posters and videos about the four elements), but without additional face-to-face support. Outcomes will be evaluated throughout the 2021 and 2022 seasons (~14 weeks per season). Primary outcome: use of Prep-to-Play will be reported via a team designate (weekly) and an independent observer (five visits over the two seasons) and defined as the team completing 75% of the programme, two-thirds (67%) of the time. Secondary outcomes: injuries will be reported by the team sports trainer and/or players. Injury definition: any injury occurring during a football match or training that results in: (1) being unable to return to the field of play for that match or (2) missing ≥ one match. Outcomes in the supported and unsupported phases will be compared using a generalised linear mixed model adjusting for clustering and time. Due to the type III hybrid implementation-effectiveness design, the study is powered to detect a improvement in use of Prep-to-Play and a reduction in ACL injuries.Ethics and disseminationLa Trobe University Ethics Committee (HREC 20488) approved. Coaches provided informed consent to receive the supported intervention and players provided consent to be contacted if they sustained a head or knee injury. Results will be disseminated through partner organisations, peer-reviewed publications and scientific conferences.Trial registration numberNCT04856241.
Epidermis stem cells have a crucial role through the processes of proliferation and differentiation, to replace cells that are constantly lost during tissue turnover or following injury. On the other hand, thyroid hormones regulate the proliferation and differentiation of epidermal cells and thus significantly influence the homeostasis of the skin. It is well known that maternal hypothyroidism during pregnancy leads to impaired development of many organ systems in their offspring. However, there is a lack of data about the influence of maternal subclinical hypothyroidism during pregnancy and lactation on the development of the skin and its derivatives in the litter. The aim of this study was to investigate the effects of maternal thyroid dysfunction on the development of the skin and its derivatives in their offspring in the early postnatal period. Antithyroid substance 6-n-propyl-2-thiouracil was added into the drinking water to female Albino Oxfords rats from the beginning of pregnancy and during lactation, with the aim to induce subclinical and overt form of hypothyroidism. Skin samples were taken from male pups within twenty-four hours and seven days after birth. The main findings of this investigation were that both forms of maternal hypothyroidism lead to serious damage of the epidermis in pups in terms of pronounced hyperkeratosis and reduction of the germinal layer along with a reduced number of hair follicles and their delayed morphogenesis. Epidermal impairments were more pronounced in pups with the overt form of hypothyroidism while offspring with the subclinical form had impairments that were less pronounced and delayed in occurrence.
This article discusses the similarities and differences of the position of Great Britain in Egypt and Austria-Hungary in Bosnia-Herzegovina in the age of New Imperialism. Comparative approach will allow us to put both situations in their historical context. Austria-Hungary?s absorption of Bosnia-Herzegovina was part of colonial involvement throughout the world. Egypt and Bosnia-Herzegovina were formally parts of the Ottoman Empire, although occupied and administrated by European Powers. Two administrators, Evelyn Baring as consul-general in Egypt and Benjamin von K?llay as civil administrator of Bosnia-Herzegovina, believed that it was their duty to bring ?civilization?, prosperity and western culture to these lands - a classic argumentation found in the New Imperialism discourse. One of the most important tasks for both administrators was fighting the national movements, which led to the suppression of political freedoms and the introduction of a large administrative apparatus to govern the newly-occupied lands. Complete control over political life and the educational system was also one of the major features of both administrations. Both Great Britain in Egypt and Austria-Hungary in Bosnia-Herzegovina never tackled the agrarian question for their own political reasons. British rule in Egypt and Austro-Hungarian in Bosnia-Herzegovina bore striking resemblances.
