Do you know what is a cerclage cable? During hip replacement and treatment of associated peri-prosthetic fractures, it is often necessary to hold the bone or fragments of bone together to create a stable environment for healing to occur. This is typically done with metal wires or cables using a technique called Cerclage. A cerclage wire or cable is wound around a bone or bony fragments to hold them together to allow them to heal.

Total hip arthroplasty has been an important surgical operation in orthopaedics in the 20th century. After many trails, major advancement in Total Hip Arthroplasty was made by Sir John Charnley in 1962, who introduced low friction arthroplasty. This consists of a polyethylene cup and 22.2 mm head, both components being fixed with methacrylate cement. In the following years there were many changes to this basic principle (model) of total hip arthroplasty. Patient education has become an important factor in improvement of function following total hip replacement.
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Berger Assistant Professor, Rush University Medical Center Degree in mechanical engineering from MIT Revolutionized hip and knee replacement surgery by developing a minimally invasive method of replacing knee joints Full Disclosure: currently being investigated by the DOJ Dr. Craig Della Valle Assistant Professor, Rush University Medical Center Board Certified - Orthopaedic Surgery Awarded the Hip Society's Frank Stinchfield Award for his research New York Times – The “Berger Study” AuthorsNew York Times June 19, 2010
5.
6. In early 2006, Dr. Berger’s follow-up care revealed X-rays showing lines in some patients where the implant met the thigh bone, an indication that the device was loose and had not fused completely Several of the loose knees eventually required early knee revision surgery Berger Study Background
7. As a result of the 2005-2006 experience, Dr. Berger, along with Dr. Della Valle, set up a study of 100 patients who received the NexGen CR-Flex Porous Knee Berger Study
10. Actual number of complications could be much higher as many patients (36%) showed signs of loosening but had not yet reached the level of revision surgeryBerger’s Study Findings:
11. “This component is still commercially available but should not be used for any patient.” Dr. Richard A. Berger Rush Medical Center Former Zimmer Consultant Dr. Berger’s Conclusion:
13. High incidence of loosening of the femoral component in legacy posterior stabilized-flex total knee replacement H.S. Han, et al, Journal of Bone and Joint Surgery – British Edition, Vol 89-B, No. 11, Nov. 2007- Korea Study Demographics: 47 patients 72 knees 44 women and 3 men All NexGen LPS-Flex - no standard LPS Study Goal: Analysis of high-flexion design for evidence of aseptic loosening and related pain Han Study (2007)
14. Patients did get better flexion then regular Total Knee Replacement (“TKR”) designed knees 111-165 degrees of knee flexion in LPS-Flex knee Versus 110-120 degree of flexion in general TKA BUT aseptic loosening was found at a higher rate in the LPS-Flex than regular TKR knees 38% of the knees (27) were loose at mean follow-up of 32 months 21% of the knees (15) were revised at mean of 23 months Han Study (2007) Study Results
15. Han Study (2007) – Specific Findings All loosening at femoral component which migrated into a position of increased flexion (i.e. additional flexion emanated from the fact that the knee was loose) “Several [physicians] have expressed concern that relatively small gains in maximum knee flexion achieved by making changes in the design may substantially reduce the stability of the prosthesis and increase the stresses on the component.” “[W]e have not previously experienced such a high rate of early loosening for any design of TKR.”
16. Are High Flexion Activities after High-Flex Total Knee Replacement Safe? Kang, S., Journal of Bone and Joint Surgery, British Edition, Vol 92-B, Issue SUPP_II, 322 Study Demographics: 72 knees were implanted All were NexGen LPS-Flex Study Goal: Determine the factors contributing to the high rate of aseptic loosening in LPS-Flex knees Kang Study (2008)

24. High Flexion Knee Designs: More Hype than Hope? In the Affirmative Ritter, M., Journal of Arthroplasty, 21(4), Supp. 1 (2006) Study Demographics: 4727 Total Knee Replacements Various ages and genders Using Biomet knee Study Goal: Evaluated the range of motion after 4727 TKA Ritter Study (2006)
25. Range of motion after a TKA is dependant primarily upon preoperative range of motion; not device design High-Flex designs may increase knee instability and possible wear Ritter Study (2006) Conclusions
26. Range of flexion after primary TKA: the effect of soft tissue release and implant design. Amed, I, et al., Orthopedics, 2009 Nov; 32(11): 811. Study reported no difference in range of movement between standard and high flexion variants of the NexGen LPS implants in a randomized controlled study. Amed Study (2009)

32. Analysis suggests that high-flex knee prostheses do not increase the post-operative maximum knee flexion compared with traditional implants The weighted mean difference between the range of flexion between a standard design and a high-flex design was 2.1⁰ “Not only is [the difference] not statistically significant, but more importantly it is not clinically significant. Additional flexion of 2⁰ . . . has no functional advantage to the patient.” Mehin Study (2010) Results

Presented by Dr. Steven H Weeden and Dr. Steven Boyd Ogden Podium Presentation: Early Loosening of MIS Tibial Implants in Primary TKA From 2005 to 2007 the authors performed 403 TKAs with a Zimmer MIS tibial component Study Demographics: All procedures were performed with a MIS technique, PS articulation, and cement 22 replacements did not have the modular stem component 381 replacements included a stem component American Academy of Orthopaedic Surgeons Conference in March 2010
37. The study reports a higher than expected rate of early loosening in cemented primary TKA with an MIS tibial component The average time to diagnosis of loosening in this study is 2.6 yrs The overall loosening rate was 5.2% (21 tibias of the 403) Early Loosening of MIS Tibial Implants
38. Of the MIS Tibias placed without a stem component, 5 tibias out of 22 failed (24%) Of the MIS tibias placed with a stem component, 16 tibias out of 381 failed (4.2%) Early Loosening of MIS Tibial Implants specifics
39. The doctors recommendation: “the use of an MIS tibia without the use of a modular stem is not recommended secondary to a high rate of early loosening in primary TKA.” Early Loosening of MIS Tibial Implants continued
