Limited prospective data about the activity of immune checkpoint inhibitors (ICIs) are available for elderly patients. The aim of our analysis was to determine the relative efficacy of ICIs versus available standard therapies [standard of care (SOC)] in subgroups defined by patients' age. Searching the MEDLINE/PubMed, Cochrane Library, and American Society of Clinical Oncology (ASCO) Meeting abstracts randomized clinical trials were identified. Data extraction was conduced according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The measured outcome was overall survival (OS). Twenty-nine randomized clinical trials (18,839 patients) were selected. As for the distribution of patients by age, all but 3 of the selected studies considered young the patients younger than 65 years (n=10,832) and elderly those with 65 years and older (n=7723); 7 studies identified a third subgroup of very elderly patients aged 75 years and above (n=421). In elderly and very elderly patients ICIs significantly reduced the risk of death by 23% compared with SOC [hazard ratio (HR), 0.77; P less then 0.00001)]. On the contrary, a lack of a survival advantage of immunotherapy was observed in the subgroup of very elderly patients (HR, 0.85; P=0.39). GPNA research buy When comparing the efficacy of ICIs between the 2 subpopulations (elderly vs. young), no significant difference in OS was observed (HR, 0.76; P=0.66). ICIs prolonged OS compared with SOC in both elderly and young patients affected by lung cancer, melanoma, and renal carcinoma, regardless of the age. In conclusion, ICIs (as monotherapy or combinations) significantly improved OS compared with SOC in both young and elderly patients with advanced cancers, regardless of the tumor type. The magnitude of this benefit is debated in patients aged 75 years and above.OBJECTIVE This study evaluates the motivational processes between employee occupational safety and health climates and behaviors using the Theory of Self-Determination in a sample of diverse small businesses. METHODS We used cross-sectional data to assess whether employee safety/health intrinsic, identified, and external motives mediate the relationship between safety/health climate and behavior. RESULTS All three types of motivation mediated the relationship between safety and health climates and behaviors. CONCLUSIONS Small businesses seeking to engage employees in Total Worker Health efforts should build strong safety and health climates because of their influence on employees' motivation to participate in health promoting and health protective programs.OBJECTIVE Determine the body composition profile of forest firefighters. Data was collected from 701 forest firefighters. METHODS We have carried out this analysis using a bioimpedance scale BC-601 of the brand Tanita® ISO 9001 Certified. RESULTS Obtained values of BMI 24.85 in women and 27.83 in men. The visceral fat index was 5 in women and 9 in men. In both cases, taking as reference the values proposed by the WHO, women are within a low-moderate risk of cardiovascular or metabolic diseases. Men are at a moderate-high risk. CONCLUSIONS The values obtained in the analysis show that forest firefighters have a moderate risk of cardiovascular and metabolic diseases in the future. It is effective to propose future works that elaborate specific physical activity plans to improve their health profile.STUDY DESIGN Patient and observer blinded, multicenter, randomized, intra-patient controlled, non-inferiority trial. OBJECTIVE To determine non-inferiority of a biphasic calcium-phosphate (AttraX® Putty) as a bone graft substitute for autograft in instrumented posterolateral fusion (PLF). SUMMARY OF BACKGROUND DATA Spinal fusion with autologous bone graft is a frequently performed surgical treatment. Several drawbacks of autografting have driven the development of numerous alternatives including synthetic ceramics. However, clinical evidence for the standalone use of these materials is limited. METHODS This study included 100 non-traumatic adults who underwent a primary, single- or multilevel, thoracolumbar, instrumented PLF. After instrumentation and preparation for grafting, the randomized allocation side of AttraX® Putty was disclosed. Autograft was applied to the contralateral side of the fusion trajectory, so each patient served as his/her own control. For the primary efficacy outcome, PLF was assessed aF EVIDENCE 1.STUDY DESIGN Secondary analysis of subjects in the control Anterior Cervical Discectomy and Fusion (ACDF) arm of Medtronic Investigational Device Exemption (IDE) trials for cervical disc arthroplasty (CDA) OBJECTIVES. To compare Patient Reported Outcomes (PROs) in patients with radiographic nonunion to patients with a solid fusion. SUMMARY OF BACKGROUND DATA The true prevalence of nonunion after ACDF is unknown. Nonunion may be under-reported, as some patients are not symptomatic enough to justify radiographic evaluation. METHODS 345 subjects enrolled in the control arm of IDE trials for CDA who had single-level ACDF with allograft and plate with 24 month data formed the study cohort. Using the 24-month post-op evaluation, subjects were divided into those who had radiographic fusion and those who did not using strict study criteria. SF-36, NDI, Neck and Arm pain NRS scores were reported at 12, 24, 36, 60 and 84 months post-op. For subjects who had secondary surgery failures, the last observations before the secondary surgery were carried forward to future visits for the analysis. RESULTS 44 (13%) patients had radiographic non-union and 301 (87%) were fused at 24 months post-op. At 24 months, PROs were similar between the two groups. Seven patients in the Nonunion group (16%) and 10 (3%) in the Fused group had additional surgery at the index level prior to the 24 -follow-up (p = 0.003). Over the 84-month follow-up a total of 9 patients in the Nonunion group (21%) and 22 (7%) in the Fused group had additional surgery at the index level (p = 0.009). CONCLUSION While the radiographic non-union rate at 24 months was 13%, PROs show that many of the radiographic non-unions were asymptomatic. Although the majority of patients with radiographic non-union did not undergo additional surgery, the rate of secondary surgeries at the index level was significantly higher in the radiographic non-union group.
