Cultural and ethnic differences in psychosocial and medical correlates of negative affect are well documented. This study aimed to compare blacks and whites for the predictive role of baseline neuroticism (N) on subsequent risk of major depressive episodes (MDD) 25 years later. Data came from the Americans' Changing Lives (ACL) Study, 1986-2011. We used data on 1219 individuals (847 whites and 372 blacks) who had data on baseline N in 1986 and future MDD in 2011. The main predictor of interest was baseline N, measured using three items in 1986...

PURPOSE OF THE STUDY Our retrospective study presents the comparison of the preoperative magnetic resonance imaging of the knee joint - MRI - and the arthroscopic finding - ASC. Its aim is to find out how a positive or a negative finding of MRI corresponds with the operative finding and how much the experience of radiologist contributes to the conformity. MATERIAL AND METHODS The MRI findings of knee joints treated surgically at two departments in 2013 and 2014 were assessed. The MRI was performed in a total of 470 patients who subsequently underwent an arthroscopic surgery...

Limited information is available on α-amino-ε-caprolactam (ACL) racemase (ACLR), a pyridoxal 5'-phosphate-dependent enzyme that acts on ACL and α-amino acid amides. In the present study, eight bacterial strains with the ability to racemize α-amino-ε-caprolactam were isolated and one of them was identified as Ensifer sp. strain 23-3. The gene for ACLR from Ensifer sp. 23-3 was cloned and expressed in Escherichia coli. The recombinant ACLR was then purified to homogeneity from the E. coli transformant harboring the ACLR gene from Ensifer sp...

OBJECTIVES: Variants within genes that encode proteins regulating fibrillogenesis such as BGN (rs1126499 C>T, rs1042103 C>T), COL5A1 (rs12722 C>T) and DCN (rs516115 C>T) have been associated with susceptibility to anterior cruciate ligament (ACL) ruptures. A miRNA mediated transcript instability was proposed for the COL5A1 association. The study aims were: (i) to investigate the association of inferred allele combinations across the COL5A1 3'-UTR, BGN and DCN genes with susceptibility to ACL rupture; and (ii) to use an in silico approach to identify miRNA binding sites common to these risk associated allele combinations...

BACKGROUND: Almost 30% of young athletic patients sustain a second anterior cruciate ligament (ACL) injury within 24months of their ACL reconstruction and returning to pivoting sports. Most patients with high athletic demand and significant anteroposterior instability often require ACL revision surgery to restore their pre-injury activity levels. CASE REPORT: A 24-year old gentleman ruptured his hamstring tendon autograft during a twisting injury seven months after his ACL reconstruction...

BACKGROUND: Venous thromboembolism (VTE) is a significant perioperative risk with many common orthopaedic procedures. Currently, there is no standardized recommendation for the use of VTE prophylaxis during anterior cruciate ligament (ACL) reconstruction. This study sought to evaluate the current prophylactic practices of fellowship-trained sports medicine orthopaedic surgeons in the United States. HYPOTHESIS: Very few surgeons use perioperative VTE prophylaxis for ACL reconstructive surgery...

BACKGROUND: There are few published studies with very long-term follow-up of combined intra- and extra-articular anterior cruciate ligament (ACL) reconstruction. PURPOSE: To analyze clinical and radiographic outcomes of over-the-top ACL reconstruction plus extra-articular lateral tenodesis with autologous hamstrings at minimum 20-year follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Of 60 originally eligible patients who underwent over-the-top ACL reconstruction with double-stranded hamstring tendon (leaving intact graft tibial insertions) and extra-articular lateral plasty (performed with the remnant part of tendons), 52 were prospectively evaluated at a minimum 20-year follow-up (mean follow-up, 24 years; 41 men, 11 women; mean age at time of surgery, 25...

We report the results of a symposium aimed at identifying validated biomarkers that can be used to complement clinical observations for diagnosis and prognosis of joint injury leading to equine osteoarthritis (OA). Biomarkers might also predict pre-fracture change that could lead to catastrophic bone failure in equine athletes. The workshop was attended by leading scientists in the fields of equine and human musculoskeletal biomarkers to enable cross-disciplinary exchange and improve knowledge in both. Detailed proceedings with strategic planning was written, added to, edited and referenced to develop this manuscript...

The effectiveness of vertical drop jumps (VDJs) to screen for non-contact ACL injuries is unclear. This may be contributed to by discrete point analysis, which does not evaluate patterns of movement. Also, limited research exists on the second landing of VDJs, potential lower limb performance asymmetries and the effect of fatigue. Statistical parametric mapping investigated the main effects of landing, limb dominance and a high intensity, intermittent exercise protocol (HIIP) on VDJ biomechanics. Twenty-two male athletes (21...

INTRODUCTION: Ultrasonographic evaluation of patients in cardiac arrest is currently not protocolised in the advanced cardiac life support (ACLS) algorithm. Potentially reversible causes may be identified using bedside ultrasonography that is ubiquitous in most emergency departments (EDs). This study aimed to evaluate the incidence of sonographically detectable reversible causes of cardiac arrest by incorporating an ultrasonography protocol into the ACLS algorithm. Secondary objectives include rates of survival to hospital admission, hospital discharge, and 30-day mortality...

Anterior cruciate ligament (ACL) is the most commonly injured ligament occurs in young adult population, which markedly reduces activity level. Anterior cruciate ligament rupture is a threat to the homeostasis of the knee. So, reconstruction of the ACL is necessary to make them fit and return to their pre-injury activity level. The choice of graft for ACL reconstruction is a matter of debate, with the BPTB graft and quadruple graft of ST-G being the two most popular options. Use of triplet graft of semi-tendinosus tendon alone without sacrificing gracilis is another option...

How to enhance tendon graft incorporation into bone tunnels for achieving satisfactory healing outcomes in patients with anterior cruciate ligament reconstruction (ACLR) is one of the most challenging clinical problems in orthopaedic sports medicine. Several studies have recently reported the beneficial effects of Mg implants in bone fracture healing, indicating the use potential of Mg devices in promoting the tendon graft osteointegration. Here, we developed an innovative Mg-based interference screws for fixation of the tendon graft in rabbits underwent ACLR and investigated the biological role of Mg-based implants in the graft healing...

BACKGROUND: A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known if an accelerated return-to-sport increases the risk of early-onset knee osteoarthritis (KOA). OBJECTIVE: To determine whether an accelerated return-to-sport post-ACLR (i.e., <10 months) is associated with increased odds of early KOA features on MRI 1-year post-surgery, and to evaluate the relationship between an accelerated return-to-sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower-limb function (good or poor)...

Anterior cruciate ligament (ACL) injuries are typically seen in cutting sports. Rehabilitation can be tried in athletes in non-cutting sports and in recreational athletes. If knee instability is experienced, the cessation of risk activities or reduction in activity level are recommended. With recurrent episodes of instability ACL-reconstruction is recommended. 65% return to sports at preinjury level after ACL-reconstruction, 18% after non-operated partial rupture and 7% after non-operated total rupture.

PURPOSE: Quadriceps femoris (QF) strength deficits at return-to-sport (RTS) after ACL reconstruction (ACLR) contribute to decreased knee function at the same time point. However, the impact of QF strength at RTS on longitudinal function has not been examined. The purpose of this study was to test the hypothesis that young athletes after ACLR with QF strength asymmetry at RTS would demonstrate decreased knee-related function and lower proportions of functional recovery at 1 year post-RTS compared to young athletes following ACLR with nearly symmetric QF strength at RTS...

Autograft has been carried out for anterior cruciate ligament (ACL) reconstruction surgery. However, it has negative aspect because patients lose their healthy ligaments from other part. We focus on a chitosan-hydroxyapatite (HAp) composite fiber as a scaffold of ligament regeneration. Chitosan- HAp composite fiber was made by using coagulation method. Chitosan-NaH2PO4 solution was coagulated with coagulation bath including calcium ion to get the mono-fiber and then treated with sodium hydroxide solution to form HAp in fiber matrix...

INTRODUCTION: During anterior cruciate ligament (ACL) reconstruction procedures, anterolateral reconstruction (ALR) can also be performed to improve the knee's rotational stability. However, the effectiveness of this supplemental technique and its impact on the risk of retears and on the onset of secondary degenerative changesare controversial. HYPOTHESIS: ALR improves control over the pivot shift, reduces the retear risk and delays the appearance of secondary degenerative lesions...

INTRODUCTION: Lateral tenodesis (LT) is performed to limit the risk of iterative tear following anterior cruciate ligament (ACL) reconstruction in at-risk patients. By adding an extra procedure to isolated ACL graft, LT reconstruction increases operating time and may complicate postoperative course. The objective of the present study was to evaluate the rate of early complications. The study hypothesis was that associating ALL reconstruction to ACL reconstruction does not increase the complications rate found with isolated ACL reconstruction...
