No differences were found related to osmolarity, pH and density between fresh and lyophilized serum. In addition, no differences were found on the conjunctival and corneal cells proliferation and differentiation in cells cultures between both serum preparations. CONCLUSION The properties of autologous serum remain after lyophilization. The lyophilized serum can be easily stored without temperature restrictions and easily reconstituted for eyedrops preparation for standard clinical use. BACKGROUND Thoracic endovascular aortic repair (TEVAR) with endograft coverage from the left subclavian artery to the celiac artery has been hypothesized to increase spinal cord ischemia. This study analyzes the impact of extended coverage on adverse outcomes and aortic remodeling in patients with complicated acute type B aortic dissection (aTBAD). METHODS From January 2012 to October 2018, 91 patients underwent TEVAR for aTBAD. Median follow-up was 3.1 (interquartile range, 1.2-4.9) years and was complete in 94% of patients. The extent of aortic endograft coverage was categorized as standard (n = 39) or extended (n = 52). Contrast-enhanced imaging scans were analyzed to determine length of coverage, maximum aortic diameters, and false lumen (FL) status. RESULTS The mean age was 52.6 ± 13.9 years, and 66% were men. The most common indications for intervention were malperfusion (42%) and refractory pain (34%). Thirteen (14%) patients required a lumbar drain (preoperative n = 3; postoperative n = 10). Mean duration between scans was 2.0 ± 1.9 years. Length of aortic coverage was significantly longer in the extended group (241.7 ± 29.2 mm vs 180.8 ± 22.3 mm in the standard group; P less then .001). In-hospital and overall mortality were 6% and 11%, respectively. There were no cases of paraplegia, and the incidence of spinal cord ischemia was 3%. After TEVAR, there was a higher incidence of FL obliteration or thrombosis at the distal descending thoracic aorta in the extended group (53% vs 16% in the standard group; P = .004). CONCLUSIONS Extended TEVAR carries a low risk of spinal cord ischemia and improves FL remodeling of the descending thoracic aorta in patients with aTBAD. This strategy may decrease the need for reinterventions on the thoracic aorta in the chronic phase of TBAD. Bronchial stenosis after chest surgery is a rare event. In upper lobectomy it is likely due to the upward movement of the remaining lobe (s) with torsion of the bronchus and edema. This case report describes the use of existing tools and prosthesis to create a novel miniature Y stent for a stenotic lobar bronchus that rapidly bifurcates, not allowing the insertion of a standard bronchial stent. BACKGROUND Bicuspid aortic valve-associated ascending thoracic aortic aneurysms (BAV-aTAAs) carry a risk of acute type A dissection. Biomechanically, dissection may occur when wall stress exceeds wall strength. Our aim was to develop patient-specific computational models of BAV-aTAAs to determine magnitudes of wall stress by anatomic regions. METHODS Patients with BAV-aTAA diameter greater than 4.5 cm (n = 41) underwent electrocardiogram-gated computed tomography angiography. Three-dimensional aneurysm geometries were reconstructed after accounting for prestress and loaded to systemic pressure. Finite element analyses were performed with fiber-embedded hyperelastic material model using LS-DYNA software (LSTC Inc, Livermore, CA) to obtain wall stress distributions. The 99th percentile longitudinal and circumferential stresses were determined at systole. RESULTS The 99th percentile longitudinal wall stresses for BAV-aTAAs at sinuses of Valsalva, sinotubular junction (STJ), and ascending aorta were 361 ± 59.8 kPa, 295 ± 67.2 kPa, and 224 ± 37.6 kPa, respectively, with significant differences in ascending aorta vs sinuses (P less then 1 × 10-13) and STJ (P less then 1 × 10-6). The 99th percentile circumferential wall stresses were 474 ± 88.2 kPa, 634 ± 181.9 kPa, and 381 ± 54.0 kPa for sinuses, the STJ, and the ascending aorta, respectively, with significant differences in the ascending aorta vs sinuses (P = .002) and STJ (P less then 1 × 10-13). CONCLUSIONS Wall stresses, both circumferential and longitudinal, were greater in the aortic root, sinuses, and STJ than in the ascending aorta on BAV-aTAAs. These results fill a fundamental knowledge gap regarding biomechanical stress distribution in BAV-aTAA patients, which when related to wall strength may provide prognostication of aTAA dissection risk by patient-specific modeling. BACKGROUND Increased mortality associated with low cardiorespiratory fitness has shown to take effect during late adulthood in previous generations. A recent rise in early death was observed in the US. We investigated the impact of low cardiorespiratory fitness during young and middle adulthood on premature death in healthy adults from recent generations. METHODS A prospective cohort study of a nationally representative sample of US Baby Boomers and Generation Xers (born 1945-1980). Mycro 3 cell line Between 1999-2004, 3242 adults aged 20 to 49 years (weighted N=59 888 450; mean age, 33.8 ± 0.2 years) underwent submaximal treadmill exercise test in the National Health and Nutrition Examination Survey study. Weighted Cox proportional hazards regression were used to evaluate the association of cardiorespiratory fitness with premature death at 65 years or younger RESULTS During a mean follow-up of 13.8 years, 104 deaths (weighted deaths N =1 326 808) occurred. Low cardiorespiratory fitness was associated with an increased risk of premature death due to all-cause (Hazard ratio [HR], low vs. high 2.26; 95% CI, 1.10 to 4.64, p for trend=.036) and cancer mortality (HR low vs. moderate/high 6.53; 95% CI, 2.38 to 17.9). Further, this association was stronger in adults aged 35 to 49 years at baseline (HR, 4.17 [95% CI, 1.19 to 9.11]). CONCLUSION We observed an inverse association between cardiorespiratory fitness during middle adulthood and premature death, which was not detected in proceeding generations. These findings suggested that low cardiorespiratory fitness might be emerging to a new risk factor for early death among US Baby Boomers and Generation Xers.
