Purpose. We report a comparison study of vertebral body stapling (VBS) versus a matched bracing cohort for immature patients with moderate (25 to 44°) idiopathic scoliosis (IS).Methods. 42 of 49 consecutive patients (86%) with IS were treated with VBS and followed for a minimum of 2 years. They were compared to 121 braced patients meeting identical inclusion criteria. 52 patients (66 curves) were matched according to age at start of treatment (10.6 years versus 11.1 years, resp. [P=0.07]) and gender.Results. For thoracic curves 25–34°, VBS had a success rate (defined as curve progression <10°) of 81% versus 61% for bracing(P=0.16). In thoracic curves 35–44°, VBS and bracing both had a poor success rate. For lumbar curves, success rates were similar in both groups for curves measuring 25–34°.Conclusion. In this comparison of two cohorts of patients with high-risk (Risser 0-1) moderate IS (25–44°), in smaller thoracic curves (25–34°) VBS provided better results as a clinical trend as compared to bracing. VBS was found not to be effective for thoracic curves ≥35°. For lumbar curves measuring 25–34°, results appear to be similar for both VBS and bracing, at 80% success.

Spinal Curve

Background Context. There is no general accepted theory on the etiology of idiopathic scoliosis (IS). An important role of the vertebrae endplate physes (VEPh) and intervertebral discs (IVD) in spinal curve progression is acknowledged, but ultrastructural mechanisms are not well understood. Purpose. To analyze the current literature on ultrastructural characteristics of VEPh and IVD in the context of IS etiology. Study Design/Setting. A literature review. Results. There is strong evidence for multifactorial etiology of IS. Early wedging of vertebra bodies is likely due to laterally directed appositional bone growth at the concave side, caused by a combination of increased cell proliferation at the vertebrae endplate and altered mechanical properties of the outer annulus fibrosus of the adjacent IVD. Genetic defects in bending proteins necessary for IVD lamellar organization underlie altered mechanical properties. Asymmetrical ligaments, muscular stretch, and spine instability may also play roles in curve formation. Conclusions. Development of a reliable, cost effective method for identifying patients at high risk for curve progression is needed and could lead to a paradigm shift in treatment options. Unnecessary anxiety, bracing, and radiation could potentially be minimized and high risk patient could receive surgery earlier, rendering better outcomes with fewer fused segments needed to mitigate curve progression.

Productivity Gap

Women underrepresentation in science has frequently been associated with women being less productive than men (i.e. the gender productivity gap), which may be explained by women having lower success rates, producing science of lower impact and/or suffering gender bias. By performing global meta-analyses, we show that there is a gender productivity gap mostly supported by a larger scientific production ascribed to men. However, women and men show similar success rates when the researchers' work is directly evaluated (i.e. publishing articles). Men's success rate is higher only in productivity proxies involving peer recognition (e.g. evaluation committees, academic positions). Men's articles showed a tendency to have higher global impact but only if studies include self-citations. We detected gender bias against women in research fields where women are underrepresented (i.e. those different from Psychology). Historical numerical unbalance, socio-psychological aspects and cultural factors may influence differences in success rate, science impact and gender bias. Thus, the maintenance of a women-unfriendly academic and non-academic environment may perpetuate the gender productivity gap. New policies to build a more egalitarian and heterogeneous scientific community and society are needed to close the gender gap in science.

BACKGROUND AND AIM:Helicobacter pyloritreatment success rates have varied. A systematic review of the success rate of anti-H pyloritherapy in Canada was performed.METHODS: All clinical trials containing Canadian data on the success rate ofH pyloritreatment were identified using MEDLINE searches, through review of references of retrieved studies and by contacting key investigators. Both randomized and open-label trials were included. Treatment effect size was calculated using a variation of Cochran’s Q method.RESULTS: Seventeen papers met the inclusion criteria. Both triple therapies consisting of a proton pump inhibitor (PPI), clarithromycin and either amoxicillin or metronidazole performed well, achieving a success rate of 84% and 82%, respectively. The cure rate of PPI-amoxicillin + metronidazole was 76%. Quadruple therapy consisting of a PPI, bismuth, metronidazole and tetracycline, given for seven to 10 days, achieved a success rate of 87%.CONCLUSION: Both PPI-based triple therapy and quadruple therapy perform well in Canada for the treatment ofH pyloriinfection.

Hospital Cardiac Arrest

Background: Cardiopulmonary resuscitation (CPR) has been a frequently performed medical intervention that increases the chance of survival of a person stricken by cardiac arrest, and there is an excellent value of diversity in the rate of successful rehabilitation in societies. Methods: A retrospective observational study was carried out. The medical records of all in-hospital and out-hospital cardiac arrest patients who underwent CPR were collected. A total of 587 people with who underwent CPR during two years between January 2017 and June 2018, using a designed form were enrolled. Demographic information, the ward which CPR was committed, hospitalization, the delay before the onset of CPR and time of the day were recorded. Results: The overall success rate of CPR in this study was 25.89%. There was no significant difference in the success rate of CPR between men and women. A comparison of age groups revealed a difference between the success rates of CPR in 14 - 64 years group compared with the group above 64. Analysis of the data revealed no difference between CPR success rates in various seasons. Investigating the occurrence of cardiac arrest and its success rate at the hospital shifting showed a significant difference between the success rate of CPR in the morning shift with the evening shift and night. The dual comparison revealed a significant difference in the success rate of CPR only between the emergency department and intensive care units. Conclusions: The current study revealed a significant difference in age group and location, and did not show any significant success rate of CPR in the presence of witnesses, location of cardiac arrest, season and gender.

Cognitive Involvement

This article focuses on the decision-making processes involved in research and knowledge integration in translation processes. First, the relevance of decision taking intranslation is discussed. Second, the psychology of decision making as seen by Jungermann et al. (2005) is introduced, who propose a categorization of decision-making processes intofour types: “routinized”, “stereotype”, “reflected” and “constructed”. This classification is then applied to the translations by five professional translators and five novices of five segments occurring in a popular-science text. The analysis reveals that the decision-making types are distributed differently among students and professional translators, which also has to be seen against the background of whether the decisions made were successful or not. The preliminary results of this study show that students resort to reflected decisions in most cases, but with a low success rate. Professionals achieve a higher success rate when making reflected decisions. As expected, they also make more routinized decisions than students. The professionals’ success rates improve with increasing cognitive involvement, while their failure rates are relatively high when making routinized decisions, an aspect worthwhile considering in translation didactics.

SummaryAim: This study was performed to analyse the impact of the choice of antithyroid drugs (ATD) on the outcome of ablative radioiodine therapy (RIT) in patients with Graves' disease. Patients, material, methods: A total of 571 consecutive patients were observed for 12 months after RIT between July 2001 and June 2004. Inclusion criteria were the confirmed diagnosis of Graves' disease, compensation of hyperthyroidism and withdrawal of ATD two days before preliminary radioiodine-testing and RIT. The intended dose of 250 Gy was calculated from the results of the radioiodine test and the therapeutically achieved dose was measured by serial uptake measurements. The end-point measure was thyroid function 12 months after RIT; success was defined as elimination of hyperthyroidism. The pretreatment ATD was retrospectively correlated with the results achieved. Results: Relief from hyperthyroidism was achieved in 96 % of patients. 472 patients were treated with carbimazole or methimazole (CMI) and 61 with propylthiouracil (PTU). 38 patients had no thyrostatic drugs (ND) prior to RIT. The success rate was equal in all groups (CMI 451/472; PTU 61/61; ND 37/38; p=0.22). Conclusion: Thyrostatic treatment with PTU achieves excellent results in ablative RIT, using an accurate dosimetric approach with an achieved post-therapeutic dose of more than 200 Gy.

Abstract Background/Introduction The PEGASUS-TIMI 54 trial showed that prolonged treatment with ticagrelor reduces the cumulative occurrence of ischemic adverse events. CLARIFY is the biggest real life registry on chronic coronary syndrome. Purpose - To evaluate the percentage of patients eligible for long-term ticagrelor therapy in the CLARIFY registry. – To compare the outcome of this subgroup of patients with those with PEGASUS exclusion criteria or without PEGASUS inclusion criteria. Methods Within the CLARIFY population, we selected post MI patients and we excluded those with missing info (post MI evaluable population). Then, we divided patients into 3 groups: excluded (meeting PEGASUS exclusion criteria, namely use of P2Y12 receptor antagonists or chronic oral anticoagulant, any stroke, coronary-artery bypass grafting in the past 5 years); eligible (meeting PEGASUS high-risk inclusion criteria, namely age≥65 years; diabetes; multivessel disease; creatinine clearance &lt;60 ml/min) and ineligible (not meeting PEGASUS high-risk inclusion criteria). We therefore compared the ischemic (CV death, MI and stroke) and bleeding (major bleeding) outcome of the 3 groups adjusting for age, sex, smoking and geographical region. Results Among the 11811 post-MI evaluable patients, 4706 (39.8%) were included in the eligible group, 5715 (48.4%) in the excluded group, and 1390 in the ineligible group (11.8%). Both the ischemic and bleeding endpoints were significantly different among the 3 groups with the excluded patients with the worst and ineligible patients with the best outcome (see table). The same trend was shown for CV death, while the occurrence of MI was not significantly different among the 3 groups. In the eligible group, the ratio between ischemic and bleeding events was 6:1, whereas between CV death and major bleeding was 3.5:1. Conclusions Around 40% of CLARIFY post-MI patients could benefit from prolonged ticagrelor therapy. In this group of patients, ischemic risk seems to be higher than the bleeding one.

Purpose: To evaluate the surgical outcomes of primary early endoscopic dacryocystorhinostomy (EnDCR) in acute dacryocystitis (AD) and to determine the optimal timing for surgery. Methods: A retrospective review of medical records was performed on consecutive patients who underwent primary early EnDCR (within 1 week) for AD between May 2010 and June 2020 (AD group) and an age- and gender-matched control group of NLDO patients who underwent EnDCR (non-AD group). The primary outcome measures were the surgical outcomes at the final follow-up examination. The secondary outcome measure was the clinical course of AD patients. Subgroup analysis was performed to determine the optimal timing of surgery by comparing the outcomes of very early EnDCR (within 3 days) and those of early EnDCR (between 4 and 7 days). Results: Forty-one patients were included in the AD group and 82 patients in the non-AD group. The anatomical and functional success rates were 87.8% and 82.9% in the AD group, and 91.5% and 84.1% in the non-AD group, which were not significantly different between the two groups (p = 0.532 and p = 0.863). In the AD group, the mean times for pain relief and resolution of swelling after surgery were 2.4 and 6.5 days after surgery, respectively. In the subgroup analysis according to the timing of surgery, the time for symptom resolution after diagnosis, the length of hospital stays, and the duration of antibiotic treatments were significantly shorter after very early EnDCR (all ps < 0.05), whereas the surgical outcomes were not different between the two groups (p = 1.000). Conclusions: Primary early EnDCR is a safe and effective procedure for the treatment of AD. In particular, very early EnDCR performed within 3 days leads to faster recovery and shortens the course of antibiotic treatment.
