FORCE-VELOCITY RELATIONSHIP BETWEEN SPRINTING AND JUMPING TESTING PROCEDURES

The aim of this study was to examine the relationship between the mechanical characteristics of the horizontal and vertical Force-velocity (F-v) profile as well as the performance variables of the sprinting and jumping testing procedures. Twenty high-level sprinters performed two maximal sprints and squat jumps against multiple external loads. Our main findings revealed very large correlations for maximal mechanical power output (Pmax) (r=0.72), as well as for performance variables between the sprinting and jumping tasks (r=-0.81) and large correlations for maximal velocity (V0) (r=0.66). The maximal force (F0) and the slope of the F-v relationship (F-v slope) were not significantly correlated between both tasks. These results suggest that both testing procedures should be performed in order to gain a deeper insight into the maximal mechanical properties and function of the lower-body muscles in high-level sprinters

Ilizarov treatment of humeral shaft nonunion in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity

Nonunion of the humeral shaft in patients with antiepileptic drug associated metabolic bone disorder constitute a challenging surgical problem difficult to treat due to seizure activity, osteoporosis, and poor stabilization options. We report a case of nonunion of the humeral shaft in an antiepileptic drug patient with uncontrolled generalized tonic-clonic seizure activity successfully treated with Ilizarov external fixator and a follow-up of 4 years

DIFFERENCES IN MAXIMAL STRENGTH CAPACITY BETWEEN ISOMETRIC SQUAT AND MID-THIGH PULL TESTS IN ELITE TRACK AND FIELD ATHLETES.

The aim of this study was to compare the vertical peak force (PF) generated during the isometric mid-thigh pull (IMTP) and isometric squat (ISqT) performed at the same knee and hip angles. Fourteen elite track and field athletes performed 3 maximal efforts of isometric IMTP and ISqT tests. The vertical PF was measured by a force platform (Kistler 9290CD, AG Winterthur, Switzerland). Our findings revealed significant higher PF and relative PF during ISqT than IMTP (Mean difference: 953 ± 224 N, p \u3c 0.001, d = 1.62 and 14.6 ± 2.4 N.kg-1, p \u3c 0.001, d = 3.8, respectively). The results of this study suggest that ISqT may be more appropriate testing procedure for identifying athletes’ maximum isometric strength capacities in elite track and field athletes

Popliteal artery damage during total knee arthroplasty

AbstractInjury of popliteal artery during total knee arthroplasty is a relatively rare complication. We report on one case of transverse semi-dissection of the popliteal artery during the tibial cut and one case of popliteal pseudoaneurysm formation caused by Hohmann retractors. Diagnosis was made early in the first case but it was delayed in the second due to misdiagnosis of deep vein thrombosis. Both injuries were managed eventually by open surgery. Postoperative clinical examination and ultrasound imaging confirmed the successful restoration of the blood flow. This case report also describes the classification system of the type of vascular damage and describes the mechanism, the clinical presentation, diagnostic modalities and treatment options for these rare complications of total knee arthroplasty surgery

Neurological and neurourological complications of electrical injuries

Electrical injury can affect any system and organ. Central nervous system (CNS) complications are especially well recognised, causing an increased risk of morbidity, while peripheral nervous system (PNS) complications, neurourological and cognitive and psychological abnormalities are less predictable after electrical injuries.PubMed was searched for English language clinical observational, retrospective, review and case studies published in the last 30 years using the key words: electrical injury, electrocution, complications, sequelae, neurological, cognitive, psychological, urological, neuropsychological, neurourological, neurogenic, and bladder.In this review, the broad spectrum of neurological, cognitive, psychological and neurourological consequences of electrical trauma are discussed, and clinical features characteristic of an underlying neurological, psychological or neurourological disorder are identified. The latest information about the most recently discovered forms of nervous system disorders secondary to electrical trauma, such as the presentation of neurological sequelae years after electrocution, in other words long-term sequelae, are presented. Unexpected central nervous system or muscular complications such as hydrocephalus, brain venous thrombosis, and amyotrophic lateral sclerosis are described. Common and uncommon neuropsychological syndromes after electrical trauma are defined. Neurourological sequelae secondary to spinal cord or brain trauma or as independent consequences of electrical shock are also highlighted

A new adaptive marine policy toolbox to support ecosystem-based approach to management

4 p.As a consequence of increasing threats to the marine ecosystems, new decision support tools are necessary to support the implementation of the Ecosystem-Based Approach (EBA) to management in order to ensure their sustainable exploitation whilst ensuring their preservation. *To operationalize Ecosystem-Based Approach (EBA) to management and translate scientific knowledge into decision tools, an innovative Adaptive Marine Policy Toolbox has been created. It provides policymakers with necessary framework and resources to develop adaptive policies according to the EBA. *The Adaptive Marine Policy Toolbox provides a one-stop single location to access all the guidelines and resources necessary to design and implement adaptive marine policies according to the Marine Strategy Framework Directive. *The toolbox presents a high transferability to additional regulations calling for the Ecosystem-Based Approach to management such as the Ecosystem Approach of the Mediterranean Action Plan and the Black Sea´s Strategic Action Plan. *The Resources existing within the toolbox are presented in a user-friendly format. The presence of assessments and models capable to cope with uncertain conditions allows for high flexibility and adaptation in management strategies when future conditions change

Advanced trauma life support course for medical students. A new era?

IntroductionTrauma represents a major public health issue and is one of the leading causes of death and disability worldwide. A systematic approach toward dealing with trauma patients was facilitated through the ATLS program, which has become a milestone in trauma care. Our new ATLS course for medical students was set in motion in 2015. Our aim was to make medical students familiar with trauma patients interactively, through a program like ATLS, and here we present the results of this endeavor.MethodsA two-day ATLS-Medical Student (MS) course was offered from November 2015 to July 2018, and analysis was performed retrospectively on the data gathered over a three-month period through online questionnaires. Before graduating, 261 newly qualified medical doctors were interviewed and evaluated as part of the ATLS course.ResultsAfter the course, the vast majority of medical students (251 MSs; 96.16%) felt more capable of managing severely injured patients and 58% of students felt that the medical services they offered were better due to the ATLS training. Regarding the educational fee for the course, 56.7% of the students reported that they felt the fee of 100 euros was fair.DiscussionThe interactive format of the course, which differs from more traditional methods of teaching, has been endorsed by medical students. Though they lack clinical experience, that does not prohibit them from acquiring more specialized or specific knowledge, enabling them to excel. Most of the students improved their skillset either in theoretical knowledge, practical skills, or even in the emotional component of the course, i.e., dealing with treating a severely injured patient. It was decided that the program would be re-evaluated and extended to all Greek Medical Schools.ConclusionThe advantage of providing doctors with trauma training at the beginning of their careers is evident. For that reason, it was decided that the program would be re-evaluated and extended to all Greek Medical Schools

Custom stems for femoral deformity in patients less than 40 years of age: 70 hips followed for an average of 14 years

Background and purpose Femoral deformity associated with osteoarthritis is a challenge for both the surgeon and the implant. Many of the patients with these deformities are young. Standard implants can be difficult to fit into these femurs. We prospectively evaluated the outcome of custom uncemented femoral stems in young patients
