In this article, the author multilaterally describes the feminine criminality relying on the doctrinal interpretations, judicial practice, statistical dates, highlighting a criminological characteristic of this kind of criminality
Contact Angle Measurement on Medical Implant Titanium Based Biomaterials
No full textAbstractThe aim of present research was to study the effect of some surface modification processes on wettability of Ti6Al4V surfaces for medical implants quantified by using the measurement of contact angle. The surface modification procedures of several disc samples were performed by sand blasting, acid etching, passivation, and their combinations. Sand blasting was done with 250...300μm SiO2 large grits. The acid etching process was performed in a dual bath of H2SO4 1n and HCl 1n (1:1) at different elevated temperatures (60°C, 80°C, and 100°C) using different process durations (1h, 3h, 6h, 12h, and 24h). Passivation was done in 30% HNO3 at room temperature. On modified surfaces we evaluated topography, by measuring roughness, and analyzing scanning electron micrographs. Contact angle was measured using static method and direct measurement of the tangent angle at the three-phase contact point on a sessile drop profile. We found that the influence of sand blasting prior to acid etching at low temperature (60°C) on contact angle is beneficial when using long acid etching times (12h and 24h). Increasing the process time for acid etching leads to a decrease in contact angle which is a desired result. Increasing the temperature of acid etching bath leads to an increase in contact angle, thus decreasing the wettability. The passivation treatment leads to an increase of contact angle on sand blasted surfaces, lowering the hydrophilic properties of surfaces, and does not influence significantly the contact angle on surface without sand blasting treatment. The best preparation procedure, in terms of wettability measured by contact angle, was found to be sand blasting, followed by acid etching in above mentioned dual acid bath at 60°C for 24hours. In this case we measured a contact angle of 46° showing good hydrophilic properties

No full textIMPROVING THE AUDIT OF FINANCIAL LIABILITIES BY DEVELOPING THE RELATIONSHIP BETWEEN THE MATERIALITY AND THE AUDIT PROCEDURES
No full textThe most important aspects of the research
are based on the overall study of legal relationships,
accounting methodologies and the spectrum of perspective
views of the financial audit of financial liabilities
presented by the author. The research is
focused on the methodological delimitation of the
materiality applicable in financial accounting and the
one applicable in financial audit for the correct
assessment of sources and their use for specific purposes,
as well as their influence on the audit results.
At the same time, the audit procedures were identified
and selected based on materiality research and
establishing the complementary relationship. The
study also focuses on the application of professional
judgment to build a reasoned structure through which
the audit procedures present a solid foundation of the
materiality applicable in the audit, delimited from
that used in financial accounting, as well as identifying
the influence and impact of these actions on
the information in the audit report
The Impact of Living Arrangements on the Prevalence of Falls after Total Joint Arthroplasty: A Comparison between Institutionalized and General Geriatric Population
No full textDue to population aging, there is an increasing need for orthopedic surgery, especially total knee arthroplasty (TKA) and total hip arthroplasty (THA). In geriatric patients, postoperative falls are common events which can compromise the success of these expensive procedures. The aim of our study was to assess the influence of living arrangements on the prevalence of postoperative falls following joint replacement. We included 441 patients after TKA or THA, living in nursing homes, alone or with family. The prevalence of falls in the first 2 years (15.2%) was significantly influenced by living arrangements: patients with TKA or THA living alone had three times higher odds of falling compared to those living with family, and institutionalized patients with THA had four times higher odds of falling compared to those living with family. Of 67 patients who fell, 6 (8.9%) needed reintervention. For TKA patients, the fall rates were not significantly different between institutions and family, indicating the interest of nursing homes in offering proper care. However, for the THA group, the results were poorer, emphasizing the need for improvement in postoperative rehabilitation. Further multi-centric studies are required for generalizing the impact of living arrangements on fall prevalence after joint replacement
Will Total Knee Replacement Ever Provide Normal Knee Function?
No full textKnee osteoarthritis or gonarthrosis is considered the most common joint disease, affecting more than 70% of subjects aged over 65 years. Its occurrence is increasing with age and is more problematic with the current rise in the incidence of obesity. In severe and advanced cases, total knee arthroplasty is recommended as a gold standard therapy for pain relief, restoration of normal knee function, and quality of life improvement. There are numerous controversies whether total knee arthroplasty is able to reach and provide end-point outcomes and restore previous function of the knee joint. Studies suggest that the surgeons’ experience, type of prosthesis used, associated pathology, underlying pathologies, risk factors, continuous passive movement, and patient expectations about the surgery may influence the outcomes to a great extent. “Normal knee function” is a statement that is hardly defined in the current literature, as authors usually refer to subjective results when analyzing outcomes. Objective results may be more straightforward, but they do not always symbolize the actual state that the patient is reporting or the actual quality of life. Our objective was to analyze and present summaries of the current literature regarding normal knee function restoration after total knee replacement surgery. Our literature review results confirm the hypothesis that subjective and objective results are difficult to interpret and unravel. Complex future trials may bring supplementary and clearer conclusions regarding knee function and kinematics, clinical improvement, patient satisfaction, and quality of life
Anterolateral Ligament (ALL) — Myth or Reality?
No full textAbstract
Although the anterolateral ligament (ALL) was described a long time ago, recent research shows a lot of interest regarding this structure. There is a high variability concerning its anatomy, especially its capsular/extracapsular situation and insertion sites. There is also some controversy about its ligamentous structure. It seems that it has a biomechanical role in restricting anterior tibial translation and internal rotation. The ALL complex seems to have a clinical significance, and a relationship with the pivot shift has been described. Although there are promising results recently, the surgical techniques of ALL reconstruction, in addition to anterior cruciate ligament reconstruction, have to be further investigated. A precise indication algorithm and patient selection criteria need to be established.</jats:p
The ACL Fixation
No full textACL rupture frequently occurs due to a pivotal movement between the tibia and femur. In lack of reconstruction surgery of the ligament, osteoarthritis appears. The ACL graft can be fitted through different systems: compression, expansion and suspension. Although different in technique, the clinical end-results show little differences
Transfemoral Approach in Revision Hip Arthroplasty: A Prospective Analysis of 36 Cases: Radiological and Functional Results at a Minimum 2 Years Follow-up
No full textBackground and Objectives: One of the most difficult aspects of hip revision is to remove the stem from the femoral canal with or without cement while maintaining the maximal amount of bone stock to obtain the best possible press-fit of the revision prosthesis. The transfemoral approach ensures direct access to the medullary canal so that the content removal is completed under direct control, while protecting the bone. This type of approach is particularly efficient for special conditions, such as deformation of the proximal femoral region, broken stems, or the presence of cement over a long distance distal to the prosthesis. The aim of this study was to evaluate the main advantages of transtrochanteric approach in hip revisions. Materials and Methods: Our series included 36 revisions performed using the transfemoral approach. We have analyzed the following postoperative radiological aspects: the length of the fixation zone distal to the osteotomized bone fragment (OBF), the gap between the OBF and the diaphysis, stem subsidence over time, and OBF consolidation. Results: The results were very good, both in terms of the rate of intraoperative complications and postoperative evolution. The fixation zone length was 4.2 cm on average (range: 2 to 5.8 cm). The distal gap between the OBF and the diaphysis was 1.2 cm on average (range: 0 to 2.3 cm). Stem subsidence was noted in four cases (11.1%). In all cases, stem subsidence occurred between three and six months and was 6 to 8 mm without affecting hip stability. OBF consolidation was radiologically confirmed for all cases at one year follow-up. Clinical assessment based on the Harris Hip Score showed an overall improvement from 43.2 preoperatively to 79.7 at 12 months and 83 at two years, respectively. The most important rate of progress was between 6 months and 12 months. Conclusions: The transtrochanteric approach has been shown to be very efficient for hip revisions. Understanding the hip biomechanics, applying a less aggressive surgical technique, and using efficient fixation methods such as cables significantly improved the results
