Contact injuries of the female field hockey players

WOS: 000445197700010BACKGROUND: Field hockey is classified as a non-contact sport, however it is clear from literature review that most injuries occur by contact. Despite the old history of the sport, field hockey has only recently started to develop in Turkey. This is the first research about the field hockey injuries which take place especially due to contact. METHODS: Ninety six Turkish female field hockey players took part in this study and they filled an anonymous questionnaire including field hockey information (position, and playing experience) and contact injury history of players in the 2011-2012 season (numbers of contact injuries, type of injuries, contact mechanism of injuries and detailed body parts injured with positions of players). RESULTS: The most common type of injury was contusion (50% of the total 382 contact injuries). Injuries caused by the contact of the ball are the main reasons of such injuries and they constitute 46% of the contact injuries. Besides, it was found out that the body part affected most commonly by contact injuries is the upper limb (48%). Defenders have the highest rate of contact injury as common as 41%. There were significant differences between types of injuries and mechanisms of the contact injuries (P=0.001). CONCLUSIONS: In sum, it was concluded that more protective clothes and equipment would make contact injuries less common and probably make field hockey more popular. The regular and systematic data collection about sport injuries will improve the prevention and control of these injuries

Targeted fetal cell-free DNA screening for aneuploidies in 4,594 pregnancies: Single center study

Background Next-generation sequencing (NGS) and discovery of fetal cell-free DNA (cfDNA) in the maternal circulation render possible prenatal screening for trisomy 21 (Down syndrome), trisomy 18, trisomy 13, and sex chromosome aneuploidies. The approach is called "fetal cfDNA screening" and in contrast to noninvasive conventional serum screening, it provides the identification of 98%-99% of fetuses with Down syndrome. Methods Retrospective analysis of targeted noninvasive prenatal testing (NIPT) (Clarigo Test) pregnancies with moderate risk, which we have reported between 2016 and 2018 years is presented. Two separate laboratory workflows and NGS platforms are used for the same targeted NIPT analysis. Results In total, 4,594 pregnant women were investigated. Initial 3,594 cases are studied by MiSeq platform, the last 1,000 cases by NextSeq. Failure rate for MiSeq platform is 10.9% and for NextSeq is 8.7%. Automatically reported cases constitute 75% of the MiSeq group and 87% of the NextSeq group. Conclusions Targeted NIPT results suggest that MiSeq platform could be used for NIPT which would be an essential option particularly for laboratories with low sample flow. And, the NextSeq platform has easier wet lab process and also increased success rate in automatic reporting which is suitable for centers with high number of NIPT cases
