Quantifying hopping and landing performances can assist coaches in identifying young male soccer players who may be at increased risk of injury. The influence of chronological age and maturation on these measures in this population is unknown. Single leg hop for distance (SLHD) and 75% horizontal hop and stick landing force (75%Hop) were examined in a cross-sectional sample (N=400) of elite male youth soccer players. Between-group differences for both chronological age (U11-U18) and stage of maturation (pre-, circa- or post-peak height velocity (PHV)) were analyzed...

Squamous cell carcinoma of the head and neck (SCCHN) comprises a large group of cancers in the oral cavity and nasopharyngeal area that typically arise in older males in association with alcohol/tobacco usage. Within the oral cavity, the mobile tongue is the most common site for tumour development. The incidence of tongue squamous cell carcinoma (TSCC) is increasing in younger people, which has been suggested to associate with a viral aetiology. Two common human oncogenic viruses, human papilloma virus (HPV) and Epstein-Barr virus (EBV) are known causes of certain types of SCCHN, namely the oropharynx and nasopharynx, respectively...

This article explores the background, creation and reception of a prominent cigarette advertising campaign from the early 1960s. The advertisements featured young couples falling in love as they shared Player's Medium cigarettes together. As such, the advertisements reflected the central place of the teenager within post-war British consumer culture. The campaign was built upon the insights of market research, particularly that carried out by Mark Abrams and his research organization Research Services Limited...

Mild traumatic brain injury is a major concern in young athletes, with an estimated 1.6 to 3.8 million reported concussions in the US annually. Familial hemiplegic migraine is a rare autosomal-dominant condition characterized by sporadic episodes of transient unilateral motor weakness which may begin at any age. We present a case of a 17-year-old male with a history of familial hemiplegic migraine who suffered prolonged symptoms following a mild traumatic brain injury during sports participation.

Sprint intensity interval training (SIT) is reported to improve blood glucose control and may be a useful public health tool. The sirtuins and associated genes are emerging as key players in blood glucose control. This study investigated the interplay between the sirtuin/NAD system and individual variation in insulin sensitivity responses after SIT in young healthy individuals. Before and after 4 weeks of SIT body mass and fat percentage were measured and oral glucose tolerance tests (OGTT) performed in 20 young healthy participants (7 females)...

Background and objective: There is a need for young physicians to take a responsible role in clinical teams, comparable to a leadership role. However, today's medical curricula barely consider the development of leadership competencies. Acquisition of leadership skills are currently a by-product of medical education, even though it seems to be a competency relevant for physicians' success. Therefore, an innovative leadership training program for young physicians was developed and validated. Training conceptualisation were based upon findings of critical incidents interviews (N=19) with relevant personnel (e...

The transition from child psychiatry to adult psychiatry is difficult. The need to reinforce this 'bridge' between the services is clear. A system focused on the assessment and orientation of adolescents, set up a year ago by Lille-Métropole public mental health service, aims to favour collaboration on a local level between the different players from the social, medical and educational sector working with young people aged between 12 and 21 in order to facilitate this transition.

Ubiquitin-specific protease 19 (USP19) is a key player in the negative regulation of muscle mass during muscle atrophy. Loss-of-function approaches demonstrate that 17β-estradiol (E2) increases USP19 expression through estrogen receptor (ER) α and consequently decreases soleus muscle mass in young female mice under physiological conditions. Daidzein is one of the main isoflavones in soy, and activates ERβ-dependent transcription. Here, we investigated the effects of daidzein on E2-increased USP19 expression and E2-decreased soleus muscle mass in young female mice...

Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement...

From an anatomical, physiological and clinical point of view, cardiovascular diseases in women are specific. Long considered as being less exposed to these risks, women are nevertheless victims of coronary disease, which remains, in developed countries, the leading cause of death in women. The situation is all the more concerning given that the number of young women presenting risk factors is constantly rising. Encouraging female patients to become players in their health care with regard to this pathology is especially important given that effective treatments exist which can improve the prognosis...

Optimal physiological and cardiovascular characteristics are essential for optimal physical performance. Different types of training regimes affect these characteristics and lead to trainee's adaptation and changes in relevant parameters. In present interventional study we have evaluated effects of six weeks sprint-strength & agility training on such parameters. Twenty four young Indian national hockey players volunteered for this study. BW(weight), BMI, BF (%body fat), LBM (lean body mass), rHR (resting heart rate), rBP (blood pressure), rDP (double-product), P/power (using Running-based Anaerobic Sprint Test), VJ (vertical jump), SP (seated shot-put test), BS (ball-hitting speed), Tm (505-agility test) & VO2max were measured, and changes (d) after specified training regime were studied...

BACKGROUND: Clinical practice guidelines (CPGs) are common tools in policy and clinical practice informing clinical decisions at the bedside, governance of health facilities, health insurer and government spending, and patient choices. South Africa's health sector is transitioning to a national health insurance system, aiming to build on other primary health care initiatives to transform the previously segregated, inequitable services. Within these plans CPGs are an integral tool for delivering standardised and cost effective care...

NF-κB is a key player in inflammatory diseases, including multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE). However, the effects of NF-κB activation on oligodendrocytes in MS and EAE remain unknown. We generated a mouse model that expresses IκBαΔN, a super-suppressor of NF-κB, specifically in oligodendrocytes and demonstrated that IκBαΔN expression had no effect on oligodendrocytes under normal conditions (both sexes). Interestingly, we showed that oligodendrocyte-specific expression of IκBαΔN blocked NF-κB activation in oligodendrocytes and resulted in exacerbated oligodendrocyte death and hypomyelination in young, developing mice that ectopically express IFN-γ in the CNS (both sexes)...

Since age-groups in soccer often comprise children born within a two-year timeframe, characteristics that define the profile of a successful player may not be appropriate for the oldest or youngest players of the same age group. Therefore, this study aimed to determine to what extent performance was influenced by age, maturation and body size in elite soccer players with barely one year age gap. Anthropometry, 15-m sprint test, modified Barrow´s agility test, Yo-Yo intermittent recovery test level 1, countermovement jump, and handgrip test were conducted in players aged twelve and under (n=82, 11...
