Quantitative sensory tests (QST) are measures of altered pain processes, but in our previous study, preoperative QST did not predict pain and disability at single time-points. Trajectory analysis accounts for time-dependent patterns. We hypothesized that QST predict trajectories of pain and disability during 1 year after low back surgery. We performed a trajectory analysis on the cohort of our previous study (n = 141). Baseline QST included electrical, pressure, heat, and cold stimulation of the low back and lower extremity, temporal summation, and conditioned pain modulation. Pain intensity and Oswestry Disability Index were measured before, and 2, 6, and 12 months after surgery. Bivariate trajectories for pain and disability were computed using group-based trajectory models. Multivariable regressions were used to identify QST as predictors of trajectory groups, with sociodemographic, psychological, and clinical characteristics as covariates. Cold pain hypersensitivity at the leg, not being married, and long pain duration independently predicted worse recovery (complete-to-incomplete, incomplete-to-no recovery). Cold pain hypersensitivity increased the odds for worse recovery by 3.8 (95% confidence intervals 1.8-8.0, P less then 0.001) and 3.0 (1.3-7.0, P = 0.012) in the univariable and multivariable analyses, respectively. Trajectory analysis, but not analysis at single time-points, identified cold pain hypersensitivity as strong predictor of worse recovery, supporting altered pain processes as predisposing factor for persisting pain and disability, and a broader use of trajectory analysis. Assessment of cold pain sensitivity may be a clinically applicable, prognostic test.

Although many trials have been made to augment the unilateral alar base depression, the ultimate aesthetic satisfaction has proven difficult to achieve. In our study, we present a novel submucosal dissection technique to harvest the vomer bone and use it as an onlay graft to correct the alar base depression.

We collected a prospective cohort study of 11 patients with unilateral cleft lip nasal deformity. Using CorelDRAW X7 software, we obtained perioperative clinical photographs to analyze the nostril and lateral lip morphometric measurements on the cleft side. Computed tomography scans were used to assess the required graft's volume and to detect resorption. We performed vomerine ostectomy and placed and fixed the bone graft in with a lag screw over the alar base depression.

The nostril width showed a significant increase, in addition to the height/width ratio. The columellar angle with the lateral lip height increased remarkably, with a general improvement in the nasal tip aesthetics.

The vomer bone graft has been shown to correct the lateral and inferior disorientation of the alar base and improve the nostril and nasal tip aesthetic measurements. The vomer bone is therefore a sufficient bone source for grafting with high viability and no resorption.

They need flaps so long that available adjacent, distant or free flaps often seem inadequate. Hence, this innovative solution was designed. Twin axial flaps were elevated along an oblique axis over abdomen, extending in opposite directions while being pedicled and pivoted at about the same transverse plane. The flaps wrapped the limb from either side and gave complete coverage. Donor sites were closed directly or skin grafted. Three weeks later flap division was done, often after a delay procedure. The technique was used in 6 cases. All patients were young males with history of electrical burns or trauma resulting in total or near circumferential defect. Required length of flaps ranged from 15 to 26 cm with length/breadth ratio ranging from 31 to 51. Double abdominal flaps could cover all the exposed structures. Limb positioning was comfortable. All flaps survived; all limbs were salvaged. The cover was soft, supple, and pinchable. This is a simple yet effective flap design to address the difficult problem of circumferential defects at hand. The conceptualization and success of this flap system may be attributed to the understanding of patterns of cutaneous vasculature discovered by Ian Taylor. When the vascular axes in a region are known, the same can be exploited to design more than 1 flap in desired orientation. In conclusion, this "Undulate-design Double Abdominal flaps Insertion-Pouch for Upper limb Reconstruction" is a new and effective solution for circumferential defects of wrist and hand.

To assess contemporary national trends of comorbidities, outcomes, and health care resource utilization in patients with aortic stenosis (AS) and end-stage renal disease (ESRD) undergoing transcatheter and surgical aortic valve replacement (TAVR and SAVR).

The National-Inpatient-Sample was used to study trends in patients with AS and ESRD undergoing TAVR and SAVR between January 2012 and December 2017. Of 12,550 patients, 5,735 underwent TAVR and 6,815 underwent SAVR. Over the years, the utilization of SAVR declined (from 82.0 to 37.7%); and increased for TAVR (from 18.0 to 62.3%; p < .001). Patients receiving TAVR were older (74.6 [9.1] vs. 66.8 years [9.1]), had a higher proportion of females (37.1 vs. 32.5%), Caucasians (68.7 vs. 60.9%) and Asian /Pacific Islanders (3.1 vs. 2.7%; p < .001 for all). The TAVR patients, despite having higher comorbidity burden (anemia, coronary artery disease, chronic pulmonary disease, congestive heart failure, cerebrovascular disease, and peripheral vascular disease) had lower inpatient mortality and complications (ST-elevation myocardial infarction, pneumonia, pneumothorax, pulmonary embolism, cardiogenic shock, cardiac arrest, and need for mechanical ventilators and vasopressors). The median length of stay (13.9-6.5 days; p < .001) and cost of stay ($311,538.16 to $255,693.40; p < .001) reduced with TAVR; but remained unchanged with SAVR. Higher proportion of patients was discharged home after TAVR vs. HS10160 SAVR.

Among patients with AS and ESRD, despite providing therapy to subjects with higher comorbidity burden, TAVR was associated with lower inpatient mortality, complications, length of stay, cost of care, and higher home disposition rates when compared with SAVR.

We aim to determine the percentage of publication and its associated factors of clinical trials (CTs) registered in Peru.

Using a cross-sectional study design, we assessed CTs registered at the CT's Peruvian Registry (REPEC) during the 2011-2016 period, and evaluated its percentage of publication and associated factors. We used a bibliographic search algorithm to determine if the CTs were published and assessed the associated factors by using a Cox regression to estimate the adjusted hazard ratios (aHR) as the magnitude of association of interest.

We analyzed 228 CTs, of which 63% were published. The regression analysis identified the year of registration (aHR 2012=1.15 [0.58-2.27]; aHR 2013=0.45 [0.21-0.95]; aHR 2014=0.89 [0.43-1.82]; aHR 2015-2016=0.16 [0.05-0.58]), total number of participants (aHR=1.12; 1.05-1.18), and phase III-IV (aHR=2.15; 0.1.16-4.03) as factors associated with the publication of the CTs.

The percentage of publication of CTs executed in Peru is insufficient, and it increases the older the year of its registration in the REPEC, mayor of the number of participating countries, and if it is a phase III or IV study.

The genetic drivers underlying malignant transformation of TGCTs have not been fully elucidated so far. The aim of the present study is to clarify the functional role and regulatory mechanism of miR-196a-5p in TGCTs. We demonstrated that miR-196a-5p was downregulated in TGCTs. It can inhibit the proliferation, migration, and invasion of testicular tumor cell lines including NT-2 and NCCIT through targeting the NR6A1 gene, which we proved its role in promotion of cell proliferation and repression of cellular junction and aggregation. Mechanistically, NR6A1 inhibited E-cadherin through binding with DR0 sites in the CDH1 gene promoter and recruiting methyltransferases Dnmt1. Further, NR6A1 promoted neuronal marker protein MAP2 expression in RA-induced neurodifferentiation of NT-2 cells and testicular tumor xenografts. Clinical histopathologically, NR6A1 was positively correlated with MAP2, and negatively correlated with E-cadherin in TGCTs. These findings revealed that the miR-196a-5p represses cell proliferation, migration, invasion, and tumor neurogenesis by inhibition of NR6A1/E-cadherin signaling axis, which may be a potential target for diagnosis and therapy of TGCTs.Conductive organic polymers are most commonly generated from the oxidation or reduction of conjugated polymers. Although such conjugated polymers are typically viewed as modern materials, the earliest examples of these polymers date back to the early 19th century. The modern era of conjugated polymers began with the first reports of their conductive nature in the early 1960s. However, it was advances in the 1970s that brought particular focus to these materials with the first example of conductivity values in the metallic regime, for which the 2000 Nobel Prize in Chemistry was awarded to Hideki Shirakawa, Alan MacDiarmid, and Alan Heeger. Unfortunately, the historical narrative of these polymers is currently quite muddled in the primary literature, with various inaccuracies commonly propagated. In an effort to present a more accurate account as a resource for the field, the present report will review the first 150 years of the four primary parent polymers-polyaniline, polypyrrole, polyacetylene, and polythiophene, from their early origins in 1834 to their rapid development in the mid-1980s.Light-controlled sequential photolysis from a single nanoparticle is a challenge for controlled release. A wavelength-selective sequential photolysis from single gold nanoparticles is reported for the first time. In particular, it is also demonstrated that such nanoparticle can be used to sequentially release two payloads in living cells. In principle, this system can be extended to sequential release of multiple different types of payloads by rational design of diverse photocleavable linkers. It is expected that this work can provide a new tool for better orderly controlling cellular events that request high spatiotemporal manners.
