Abstract Introduction: Unlike other team sports on the court, volleyball lacks physical contact between players, the teams being separated by the net. However, lower limb injuries take place during spiking and blocking trough unintentional and illegal intrusion of a player in the opponent’s court. Due to the specificity of the game, the joints of the upper limbs are also subject to overload. The purpose of this study is to analyze the international literature on injury and trauma in performance volleyball. Methods: We analysed several studies about injuries in performance volleyballwhich were identified using online databases: Google Scholar, EBSCO, Springer, Elsevier, and Scopus. Results: The injury patternshows the ankle sprain as being by far the most common injury in volleyball with a percentage of 31.9%. The knee is the second most injured anatomic site, 17.38% of injuries affecting this joint. Third most frequent injury affects the fingers 13.44%, followed by lower back 12,38% andshoulder trauma 12.18%. The hand is injured in 6.97%, while other injuries were found in 5.25% of cases. Conclusions: The need for in depth analysis of volleyball injuries still persists. Analysing the literature we are comming to understand the mechanisms that produce the injuries with the purpose of finding metods to avoid these unfortunate events before they happen. It is no longer enough to recover from an injury, it must be prevented entirely if possible. Time spent by a player recovering may negatively affect the team's performance. Injury prevention measures must occupy an important place in training. Coaches should take into acount all the factors that influence injury incidence and design the training plan accordingly.

Abstract Rugby union has one of the highest injury incidence rates in team sports, however, most of the available data focus on the epidemiology of injuries in countries where rugby is popular. We aimed to report the incidence rate and relevant epidemiological aspects of injuries occurred in a group of Portuguese male rugby players. A prospective cohort study was conducted with a group of 45 senior and 32 under-18 male players (total of 77 players). Outcome measures included injury incidence, position, type, location and severity of injuries. The match injury incidence for all players was 55.84 per 1000 player match-hours (66.66 for seniors, 42.85 for under-18), while mean time-loss for injury was 20.79 days. No statistical differences were found between groups. Lower limb injuries accounted for 60.5% of all injuries, while joint/ligament injuries were the most prevalent type. Contact events were responsible for 65.1% of injuries. Despite the limitations, the obtained data are consistent with the literature. Time-loss injuries seem highly prevalent in rugby union and the incidence rates found in this Portuguese-based study were lower than the reported for international and senior men’s professional rugby union, but higher than those occurring in community rugby in tier-1 countries. The authors believe these data reinforce the need to develop and implement effective injury surveillance and prevention programs.

ABSTRACT Introduction Army recruit injuries occurring during basic training can lead to high personal and organizational burdens potentially threatening deployment capability. Previous military surveillance describing recruit injury as defined by physical therapy presentations is limited to 1-year duration or includes only male infantry recruits or trained personnel. Research describing injury incidence and trends specific to New Zealand Army basic training recruits over a longer period will better inform future injury prevention programs. Aims To identify the incidence and patterns of injuries reported from physical therapy presentations for New Zealand Army recruits undertaking basic training over a 4-year period. Materials and Methods This retrospective observational study identified injuries from physical therapy service presentations in New Zealand Army recruits from 2008 to 2011. All male and female New Zealand Army recruits who presented to physical therapy, following medical triage, were included. Recruit physical therapy presentations for injury and respiratory and other conditions were collated. Injury incidence was grouped by body region (upper limbs, lower limbs, and combined spinal regions) and site (joint or segment), and cumulative and injury incidence rates were calculated. Results One thousand eight hundred and ninety-six (1,697 males and 199 females) New Zealand Army recruits commenced basic training between 2008 and 2011. One thousand six hundred and eighty-three physical therapy presentations occurred for recruit injury during New Zealand Army basic training over 4 years. Lower limb injuries accounted for over 75% (n = 1,285) of the overall demand for physical therapy service during recruit basic training. Injuries sustained at the knee and below accounted for 67% of all reported injury presentations. Conclusion Four years of injury surveillance using physical therapy presentations identified the lower limb, with the knee and below as the most commonly injured regions in New Zealand Army recruits. Injury prevention interventions for New Zealand Army recruits should aim to reduce lower limb injuries. Future research on injury surveillance would benefit from incorporating clear injury and severity definitions, established injury classification systems, and standardized incidence calculations.

Context:  Professional horse racing is considered a high-risk sport, yet the last analysis of fall and injury incidence in this sport in Ireland was completed between 1999 and 2006. Objective:  To provide an updated analysis of the fall and injury incidence in professional flat and jump horse racing in Ireland from 2011 through 2015, compare it with the previous analysis, and detail the specific types and locations of injuries. Design:  Descriptive epidemiology study. Setting:  A medical doctor recorded all injuries that occurred at every official flat and jump race meeting for the 2011 through 2015 seasons using standardized injury-report forms. Main Outcome Measure(s):  Injury and fall rates and their 95% confidence intervals (CIs) were reported for flat and jump racing. Incidence rate ratios and 95% CIs were calculated between flat and jump racing, between the 1999–2006 analysis and the current results, and between 2011 and 2015. The distribution of injuries for type and location of injury was reported. Results:  Compared with flat racing, jump racing had significantly more falls per 1000 rides (49.5 versus 3.8), injuries per 1000 rides (10.1 versus 1.4), and injuries per 1000 meetings (776.0 versus 94.1). However, the rate of injuries per 1000 falls was significantly higher in flat racing (352.8 versus 203.8). An increase in injuries per 1000 falls between 2011 and 2015 was found in flat racing (P = .005). Since the previous analysis, a significant increase in injuries per 1000 rides and falls was noted in jump racing. Soft tissue injuries were predominant in flat and jump racing (61.54% and 68.80%, respectively), with fractures the second most common injury (15.38% and 18.06%, respectively). Concussions were more prevalent from flat-racing falls (incidence rate ratio = 0.30; 95% CI = 0.15, 0.61). The lower limb was the most frequent location of injury (32.89%) in flat racing; however, in jump racing, upper limb injuries (34.97%) were predominant. Conclusions:  An update on professional flat- and jump-racing fall and injury epidemiology is provided. Further research to identify risk factors for injury, design and investigate the feasibility of injury-prevention strategies, and document their effects on fall and injury incidence is required.

AbstractProspective studies on overuse injuries and their impact on athletic training among youth team sports are scarce. The purpose of this study was to investigate the incidence, severity and player related risk factors of overuse injuries among young (12–20 years) basketball and floorball players. A total of 387 players participated in a 3-year prospective study. Each player completed a baseline questionnaire regarding their background information. Overuse injuries that prevented players to fully or partly participate in their regular training were collected. In all, 204 overuse injuries were registered (injury incidence 1.51 injuries/1 000 h of exposure; 95% CI 1.35–1.78). Most of the injuries involved the knee (35%) and lower back (21%), and were classified as severe (44%). Injury incidence was 1.51 (95% CI 1.2–1.82) and 1.61 (95% CI 1.32–1.91) in basketball and floorball, respectively. Incidence was significantly higher among female compared with male players (incidence rate ratio 1.58; 95% CI 1.20–2.09). Previous injury and playing at adult level were the strongest factors associated with occurrence of an overuse injury. In conclusion, overuse injuries of the knee and low back are relatively common in youth basketball and floorball. Effective prevention strategies as well as training load monitoring is needed in youth team sports.

Introduction: Injuries are the causes of irreparable damages and costs in urban and rural settings. Preventive procedures are effective if correct related information is gathered and provided. Therefore, this study aimed to investigate the injury patterns and related factors in a large teaching hospital. Methods: The current cross-sectional study was conducted at Edalatian Emergency Center, Mashhad, Iran, in 2016. All study subjects were extracted from the Hospital Information System (HIS).The demographic characteristics and injuries-related factors of 6,350 patients were extracted from the HIS. The extracted variables were emergency severity index (ESI), type of referral, referral reason, insurance organizations, age, anatomic site of injuries, and month of referral. The data were analyzed in SPSS software (version 21) using the descriptive statistics method (frequency and percentage). Results: The majority of the study population was composed of males (%76.4). In total, 98.3% of the patients were classified into the semi-urgent and non-urgent levels, and 75.6% of the cases were affected in the right upper extremity. The most common age group was between 10-20 (69.4%) years, and the majority of the cases were admitted in June, July, and August. Conclusion: The current study determined the pattern and most important reasons for injuries' referral to an emergency department. Accordingly, the injuries were more frequent in the young people and active human force in our community. Furthermore, there was a significant difference among the frequencies of injury incidence in the summer holidays. It seems necessary to develop preventive procedures for injuries.

Over the past few decades, different clinical diagnostic algorithms have been proposed to diagnose malignant melanoma in its early stages. Furthermore, the detection of skin moles driven by current deep learning based approaches yields impressive results in the classification of malignant melanoma. However, in all these approaches, the researchers do not take into account the origin of the skin lesion. It has been observed that the specific criteria for in situ and early invasive melanoma highly depend on the anatomic site of the body. To address this problem, we propose a deep learning architecture based framework to classify skin lesions into the three most important anatomic sites, including the face, trunk and extremities, and acral lesions. In this study, we take advantage of pretrained networks, including VGG19, ResNet50, Xception, DenseNet121, and EfficientNetB0, to calculate the features with an adjusted and densely connected classifier. Furthermore, we perform in depth analysis on database, architecture, and result regarding the effectiveness of the proposed framework. Experiments confirm the ability of the developed algorithms to classify skin lesions into the most important anatomical sites with 91.45% overall accuracy for the EfficientNetB0 architecture, which is a state-of-the-art result in this domain.

The Impact

The soccer injury rate is distinctly higher during matches than the training sessions. Rules determine how to play, generating specific kinds of fatigue which is associated with the injury incidence. No research has evaluated the impact of potential rule-induced physical demands in soccer or comparing sports. Understanding the differences might be useful for enhancing rules (e.g., safer sport). Therefore, the aims of this study were: a) to described the differences in the rule-induced physical demands of soccer, futsal, basketball, and handball; and b) to evaluate whether soccer rule-induced physical demands are different than the other invasion intermittent team sports, focusing the impact of the substitutions rules. Data were collected from different sports rules (i.e., soccer, futsal, basketball, and handball), and performed hypothetical corrections to equate the other team sports to the soccer (i.e., court dimensions/number of players). The data showed that soccer has higher rule-induced physical demands: lower substitutions, higher dimensions in absolute (eight to 15 times), and relative (four to eight times) values. Hypothetical corrections showed that soccer has remarkably large differences. Therefore, we conclude that soccer has remarkably higher rule-induced physical demands than other team sports, and allowing unlimited substitutions in soccer is a must.

Grey literature, documentation published outside traditional commercial channels, is not very often taken into account by art librarians in Argentina, judging by searches on online databases. However, experience with grey literature at the Fundación Espigas, the highly specialized Argentinian art information center in Buenos Aires, is changing this point of view. The Center’s database offers access to a great corpus of such publications, especially to ephemera such as private view cards, pamphlets, auction catalogues, catalogues of solo and group exhibitions and posters. This ‘minimal documentary information’ has an important place as a resource, and would prove invaluable for any research project on Argentine art in the future. Indeed this material is not grey but unexpectedly brilliant at providing rich and hidden information.

The pressure for children to excel and succeed in sport continues to mount. Although resistance training for youth was in disfavor by many organizations even into the early 21st century, children’s training programs are more closely resembling the volume and intensity of adult programs. The physiological maturation of adolescent youth may impact their response to advanced training programs. Furthermore, the pressure to specialize in specific sports rather than engage in a variety of sporting activities may affect not only training responses but also injury incidence. The highlighted articles first illustrate the training-specific responses of prepeak and postpeak height velocity stage youth with more specific training stimuli needed for the postpeak height velocity stage youth. Second, individual sports tend to promote earlier and greater specialization compared with team sports, which tend to result in a higher proportion of overuse injuries. Based on the findings of these 2 studies, the planning and implementation of high-intensity training for youth, such as plyometrics, should take into consideration the physical maturation of the child and that the prevention of overuse injuries would benefit from a more varied participation in sports and activities.
