Graft Choice and the Incidence of Osteoarthritis After Anterior Cruciate Ligament Reconstruction: A Causal Analysis From a Cohort of 541 Patients

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is important to prevent knee osteoarthritis. Neither of the 2 most common graft techniques-the patellar tendon (PT) or hamstring tendon (HS) graft-has demonstrated superiority in terms of the long-term osteoarthritis rate. HYPOTHESIS: Based on the International Knee Documentation Committee (IKDC) radiographic grading system, PT grafts decrease the incidence of osteoarthritis by providing better knee stability as compared with HS grafts over 12 years of follow-up. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All adults with a first ACL rupture who underwent surgery with a PT or HS graft technique between January 2002 and December 2003 were included in the 2014 French Society of Orthopedic Surgery and Traumatology Symposium database. Baseline characteristics were collected. The primary endpoint was the occurrence of moderate to severe osteoarthritis in each group. The secondary endpoints included clinical subjective evaluations by the IKDC score and Knee injury and Osteoarthritis Outcome Score. To control the differences in baseline characteristics, the data were analyzed with propensity score matching. RESULTS: In the cohort, 541 patients from 18 centers were included: 311 PT and 230 HS ACL reconstructions. The baseline characteristics were similar after inverse probability weighting treatment (IPWT). The occurrence of osteoarthritis was similar after IPWT (19.3% for PT and 19.6% for HS, P = .94). Age at surgery >29 years and IKDC osteoarthritis stage B at the index surgery were identified as risk factors for moderate to severe osteoarthritis. Most functional outcomes were significantly higher in the HS group; however, the difference between groups remained <10 points. Of the 106 patients who needed a medial meniscectomy, the proportion of patients with moderate to severe osteoarthritis was much higher in the HS group (43.5% vs 18.3%, P = .006). However, after IPWT, the difference was not statistically significant. CONCLUSION: At 12 years of follow-up, neither graft technique was superior to the other in terms of the rate of osteoarthritis

Switching from a two-tablet regimen of tenofovir/emtricitabine and efavirenz to a one-tablet regimen may affect patients' perceptions and drug management.

Simplification of antiretroviral therapy enhances a patient's adherence but a new formulation could also lead to new adverse events and changes in daily routine. This study compared medication adherence, tolerance and satisfaction among subjects switching from a two-tablet tenofovir/emtricitabine/efavirenz regimen to a one-tablet regimen. Clinical and sociodemographic data were collected and three surveys were administered at month 0 (=switch), and then 1 and 4-6 months after the switch: the Beliefs about Medicines Questionnaire, the HIV-symptom index questionnaire, the Short HIV Treatment Satisfaction Questionnaire, the Swiss HIV Cohort Study (SHCS) two-item adherence questionnaire, and a questionnaire on daily combination antiretroviral therapy (cART) management. Medication adherence of a subgroup of subjects was routinely monitored using an electronic device (MEMS(™) ). Eighty-eight subjects gave informed consent to participate in the study. The subjects' back-switch rate was 7% (six of 88). Subjects who did not back-switch preferred the one-tablet regimen (median = 2; IQR = 1.3-2.5; on a -3 to 3 scale), but no change in adherence was found (10 of 46 nonadherent subjects; P = 1.00). The perception of treatment necessity score decreased (P = 0.004), the efavirenz blood level increased (14%; P = 0.04), and association/dissociation of cART with food intake evolved (P = 0.01) after the switch. Subjects listed equivalent numbers of symptoms during the three visits. The one-tablet regimen was preferred but the number of back-switches was not negligible. The perception of treatment necessity score decreased with the simplification of the regimen from a two-tablet to a one-tablet formulation, which could negatively impact adherence. Switching is a sensitive time in a patient's treatment life and professionals should pay particular attention to patient's perceptions of treatment during such a transition

An Adherence-Enhancing Program Increases Retention in Care in the Swiss HIV Cohort.

This study tested a theory-based adherence-enhancing intervention: the "Interprofessional Medication Adherence Program" (IMAP) to increase human immunodeficiency virus (HIV) retention in care. We retrospectively compared our intervention center (intervention group [IG]) with a standard of care center (control group [CG]) both participating in the Swiss HIV Cohort Study between 2004 and 2012. Endpoints were defined as >6-month and >12-month gaps in care for intervals of care longer than 6 and 12 months without any blood draw. Inverse probability of treatment weights was used to adjust for differences between patients at the 2 centers. Viral failure was defined as ribonucleic acid ≥50 copies/mL after 24+ weeks on antiretrovirals. The IG included 451 patients, CG 311. In the IG, 179 (40%) patients took part in the IMAP for a median of 27 months (interquartile range, 12-45). Gaps in care of ≥6 months were significantly more likely to happen in the CG versus IG (74.6% vs 57%, P < .001). The median time until the first treatment gap was longer in the IG vs CG (120 vs 84 weeks, P < .001). Gaps in care of ≥12 months evaluated in 709 (93%) patients were significantly more likely to occur in the CG compared with the IG (22.6% vs 12.5%, P < .001). The rate of viral failure was significantly lower in the IG (8.3% vs 15.1%, P = .003). This study, in a real-world setting, shows the effectiveness of the IMAP to reduce 6- and 12-month gaps in follow up among people with HIV. These results should be confirmed by studies in other settings

Cardiovascular safety of rapidly accelerated fibrosarcoma B-type and/or mitogen-activated extracellular signal-regulated kinase inhibitors: A mixed approach combining a meta-analysis and a pharmacovigilance disproportionality analysis.

The risk of cardiovascular adverse events from rapidly accelerated fibrosarcoma B-type (BRAF) and mitogen-activated extracellular signal-regulated kinase (MEK) inhibitors is not fully characterized. To evaluate the cardiovascular adverse events risks related to BRAF and/or MEK inhibitors in randomized placebo-controlled clinical trials and in the real-life setting. We used two approaches. First, we conducted a systematic review and meta-analysis of randomized placebo-controlled clinical trials reporting the incidence of cardiovascular adverse events for BRAF and/or MEK inhibitors in cancer patients. Second, we performed a disproportionality analysis, using age- and sex-adjusted reporting odds ratios (arORs) and their 95% confidence intervals (CIs) from the World Health Organization's pharmacovigilance database (VigiBase®) of anticancer drug-associated reports, to investigate real-life data. MEK inhibitors increased the risk of ejection fraction decrease (odds ratio [OR] 3.35, 95% CI 1.58-7.07), peripheral oedema (OR 2.87 95% CI 1.93-4.27) and syncope (OR 6.71, 95% CI 3.00-14.99) compared with placebo in randomized placebo-controlled clinical trials. BRAF and MEK inhibitor combination therapy further increased the risk of ejection fraction decrease. In the disproportionality analysis, we found over-reporting of ejection fraction decrease (arOR 8.42, 95% CI 7.03-10.09), peripheral oedema (arOR 1.39, 95% CI 1.17-1.66), syncope (arOR 1.56, 95% CI 1.22-1.99), torsade de pointes/QT prolongation (arOR 6.13, 95% CI 5.04-7.47) and supraventricular arrhythmias (arOR 1.50, 95% CI 1.21-1.85) for BRAF and MEK inhibitors. BRAF and MEK inhibitors were not associated with hypertension in either approach. In conclusion, MEK inhibitors increase the risk of ejection fraction decrease, peripheral oedema and syncope in randomized placebo-controlled clinical trials. Real-life data confirm these findings, and suggested additional risks of torsade de pointes/QT prolongation and supraventricular arrhythmias with BRAF/MEK inhibitors

Effect of single-unit transfusion in patients treated for haematological disease including acute leukemia: A multicenter randomized controlled clinical trial

International audienceBackground: Retrospective studies in hematological unit have suggested that single red blood cell (1-RBC) unit transfusion policy may reduce the number of RBC used without negative clinical impact.Method: Acute leukemia patients requiring intensive chemotherapy or patients receiving autologous or allogeneic transplantation were randomly assigned to receive either single RBC (1-RBC arm) or double RBC (2-RBC arm) per transfusion with a hemoglobin trigger of 8 g/dL. The primary composite endpoint was the percentage of patients experiencing serious complications, such as a non-hematological adverse event grade ≥ 3 or intensive care admission or death.Findings: A total of 981 and 592 RBC transfusions were required in the 1-RBC arm (n = 125) and the 2-RBC arm (n = 120), respectively. The mean pre-transfusion hemoglobin levels were 7.49 ± 0.83 g/dL in the 1-RBC arm and 7.46 ± 0.67 g/dL in the 2-RBC arm (p = 0.275). The predefined non-inferiority criteria was achieved with 28/125 patients reaching the primary endpoint in the 1-RBC arm (22.4 %) and 28/120 patients in the 2-RBC arm (23.3 %) (Risk difference 0.009; 95 %, Confidence interval [-0.0791 to 0.0978], p = 0.021). The median (IQR) of RBC units transfused per patient was 7 (4-12) in the 1-RBC arm and 8 (4-12) in 2-RBC arm. Hemoglobin levels at discharge were also comparable in both arms.Interpretation: The results of this trial indicate that a single RBC transfusion policy is not inferior to a double RBC transfusion policy for patients receiving a bone marrow transplant or intensive chemotherapy in a hematological intensive care unit. However, the single RBC transfusion policy did not reduce the number of RBC units transfused per stay
