Abstract Background Ice hockey injuries epidemiology is still poorly understood and very few studies are focused on it, especially about professional players. Methods Our prospective study collected all injuries occurring on ice during practice and games over 7 years (2006–2013) in a professional hockey team playing in the 1st division championship in Switzerland. Results During the 7 seasons, we recorded a total of 525 injuries and 190 injuries with time loss (TL). Mean injuries incidence was 5.93 (95% CI 5.28 to 6.27) injuries/1000 h/player and with time loss 2.14 (95% CI 1.79 to 2.39) injuries/1000 h/player. The lower limb was the most affected part of the body, with a total of 40.4% of all injuries, mostly knee Medial Collateral Ligament tear and muscle adductors/abdominal sprain. For the upper limb, shoulder was the most affected joint with mostly acromioclavicular sprain and shoulder dislocation. Forwards had a significant (p < 0.05) higher risk than defensemen for knee Medial Collateral Ligament (MCL) tear. There was no significant difference in the concussion risk between forwards and defensemen, but defensemen had a significant higher risk (p < 0.05) to have a more severe concussion. Conclusion This study provides a better understanding about professional ice hockey epidemiology, which is still insufficiently researched and understood. We also found some significant risk factors, being a forward for knee MCL tear, being a defensemen for concussion severity. Concussion program prevention seems to be effective but it is crucial to continue the follow up of concussion on long term and expand the surveillance system to all the League.

A prospective study on steatocrit value in full-term or preterm newborn babies of~ 2 days of age in Dr. Pimgadi Hospital, Medan is reported. This study was conducted from December 7, 1992, to February 7, 1993; there were 72 newborn babies (37 males and 35 females). The body weight was> 2500 gin 60 babies and s. 2500 gin 12 babies. The median steatocrit value in babies with body weight of> 2500 g was 9%, and it was 32% in babies less than 2500 g of body weight. The proportion of babies with > 25% steatocrit value was larger in babies less than 2500 g than that in 2500 g by the diet patterns of breast milk, breast milk and milk formula, milk formula. The proportion of babies with < 25% steatocrit value was higher in babies with body weight of< 2500 g than that in babies > 2500 g for those who had either breast milk, breast milk and milk formula or milk formula. There was significant difference (p<0,05) in the steatocrit levels between babies with the body weight of > 2500 g and those who had body weight of ≤ 2500 g.

Cancer-related microRNAs (miRNAs) are emerging as non-invasive biomarkers for colorectal cancer (CRC). This study aimed to analyze the correlation between the levels of tissue and plasma miRNAs and clinicopathological characteristics and surgical resection. This study was a prospective study of CRC patients who underwent surgery. Forty-four sample pairs of tissue and plasma were analyzed. The miRNA levels were evaluated by RT-qPCR. The level of tumor tissue MIR92a showed a significant difference in CRC with lymph node metastasis, stage ≥ III, and high lymphatic invasion. In preoperative plasma, there were significant differences in CRC with stage ≥ III (MIR29a) and perineural invasion (MIR21). In multivariate analysis of lymphatic invasion, the levels of both preoperative plasma MIR29a and tumor tissue MIR92a showed significant differences. Furthermore, in cases with higher plasma miRNA level, the levels of plasma MIRs21 and 29a were significantly decreased after the operation. In this study, there were significant differences in miRNAs levels with respect to the sample type, clinicopathological features, and surgical resection. The levels of tumor tissue MIR92a and preoperative plasma MIR29a may have the potential as a biomarker for prognosis. The plasma MIRs21 and 29a level has the potential to be a predictive biomarker for treatment efficacy.

Abstract Study question Is there any association between male infertility and the polymorphic variants of Mitochondrial Nicotinamide Adenine Dinucleotide Hydride dehydrogenase (NADH) Subunit 4 (MT-ND4)? Summary answer Our findings suggested that male infertility was correlated to rs2853495 and rs869096886 SNPs in MTND4. What is known already The rate of mutations in the mtDNA, the powerhouse of the cell, is high due to the lack of histones and DNA repair mechanisms. Therefore, mutations that occur in the mitochondrial genome, play a major role in some human genetic disorders. 15 - 30% of male infertility are related to genetic predisposition. Sperm containing defective mitochondria cannot effectively produce ATP and more likely to produce reactive oxygen species (ROS) and free radicals, thereby causing a defect in mtDNA, make trouble energy, and deteriorate motility and fertility. Study design, size, duration: A prospective study carried out between 2018 and 2019. 112 semen samples were collected in this study. Participants/materials, setting, methods The present study was carried out at the department of Obstetrics and Gynecology, University of Saarland, Germany. Samples were divided into 68 subfertile and 44 fertile men. Mitochondrial DNA was extracted using a QIAamp DNA Mini Kit, after that the mtDNA was amplified by using REPLI-g Mitochondrial DNA Kit. Polymerase chain reaction (PCR) was used to amplify MT-ND4 gene. Then, samples were purified and sequenced using the Sanger method in the Microsynth Seq lab, Germany. Main results and the role of chance The genotypes frequencies of the study population showed a statistically significant association between rs2853495 G&gt;A (Gly320Gly) and male infertility (P = 0.0351). Similarly, the allele frequency test showed that rs2853495 G&gt;A (Gly320Gly) and rs869096886 A&gt;G (Leu164Leu) were significantly associated with male infertility (adjusted OR = 2.616, 95% CI = 1.374 - 4.983, P = 0.0028; adjusted OR = 2.237, 95% CI = 1.245 - 4.017, P = 0.0073, respectively). On the other hand, no statistically significant difference was observed between the asthenozoospermia, oligozoospermia, teratozoospermia, asthenoteratozoospermia, oligoasthenoteratozoospermia, oligoteratozoospermia subgroups of subfertile males and the fertile ones. Limitations, reasons for caution The size number of the study samples. Wider implications of the findings: A larger prospective study will be required to confirm these associations of mitochondrial gene polymorphisms rs2853495 and rs869096886 in MT-ND4 and male infertility and to clarify the definite effect of the mitochondrial genetic variations on male infertility.

Background and Objective. Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias. There is evidence of the increased prevalence of gastroesophageal reflux disease in patients with IPF. The aim of this prospective study was to evaluate reflux in patients with IPF by analyzing the scores of the reflux cough questionnaire, measurement of pepsin in exhaled breath condensate (EBC) to detect extraesophageal reflux, and Helicobacter pylori serology to evaluate the prevalence of this stomach bacterium in patients with IPF. Material and Methods. The Hull airway reflux questionnaire (HARQ) was completed by 40 patients with IPF and 50 controls in order to evaluate reflux symptoms. EBC was collected from 23 patients (17 patients with IPF and 6 controls) for measurement of pepsin by the lateral flow technique. A prospective study of 57 subjects (34 patients with IPF and 23 controls) for H. pylori antibody detection by ELISA was performed. Results. Significantly higher HARQ scores (maximum score, 70) were recorded in patients with IPF compared with controls (19.6 [SD, 12.4] vs. 3 [SD, 2.9], P<0.001). There was no significant difference in EBC pepsin positivity between patients with IPF and controls (2 of the 17 patients vs. none of the 6 controls, P=0.38). There was no significant difference in H. pylori serology between patients with IPF and controls (17 of the 34 patients vs. 14 of the 23 controls, P=0.42). Conclusion. Patients with IPF had significantly increased scores of airway reflux symptoms. However, no objective evidence of extraesophageal reflux or H. pylori infection in patients with IPF was obtained in this study. The role of gastroesophageal and extraesophageal reflux in pathogenesis of IPF should be evaluated in a larger prospective study.

OBJECTIVES: To assess the occurrence of epileptic seizures (ES) in children and adolescents with hydrocephalus and their relationship with ventriculoperitoneal shunt (VPS) treatment. METHODS: Retrospective study of 45 patients from both genders, aged 0 to 18 years, with hydrocephalus and presenting with ES or not. The following variables were analyzed: gender, hydrocephalus etiology, age at diagnosis, age at initial VPS treatment, age at first ES and types of ES. RESULTS: Data analysis showed the following: 20 (44.4%) presented with ES, 13 (65%) of the girls and seven (35%) of the boys. There was a predominance of ES in the girls, but with no statistically significant difference. In total, 13 (65%) patients used VPS. Of the 13 patients with VPS and ES, it was observed that the onset of ES was after VPS in 10 (76.9%) individuals, whereas it occurred before VPS in two (15.4%). CONCLUSIONS: The results showed no association between VPS treatment and ES (ρ=0.832); however, most of the patients presented with their first ES episode after VPS, suggesting a possible relationship between this treatment and the occurrence of ES. A larger sample and a prospective study might answer this question.
