6 and 15.8 points at a 0-100 NRS scale. The absolute effect of true acupuncture was 26.1 points for low back pain (relative effect of 3.5 and 9.4 points to sham and conventional therapy), 34.9 points for other pain body locations (relative effect of 12.3 and 19.1 points to sham and conventional therapy), in patients with a baseline pain intensity of 60 points. Conclusion The treatment duration of acupuncture will not be less than 5 weeks. Higher analgesic effect was related to higher baseline pain intensity and pain location of neck, shoulder and knee.Objectives To evaluate the feasibility and efficacy of transcatheter aortic valve replacement (TAVR) in patients with small sinus of Valsalva (SOV). Background Patients with small SOV are considered unfavorable for TAVR since it carries risk of coronary obstruction after valve implantation. Therefore, these patients with small SOV were excluded from previous clinical trials. Methods Between February 2017 and February 2019, a total of 139 consecutive patients with severe aortic stenosis (AS) undergoing TAVR were prospectively enrolled in the Tokai Valve Registry. Patients with small SOV who were treated with smaller size of self-expandable transcatheter heart valve (THV) than expected by perimeter-based sizing were included in this study. Eleven patients (7.9%) were included. Results Mean age was 86.5 ± 3.8 years and median STS Score was 8.5% (interquartile range 6.3-12.3%). Device success was accomplished in all patients and no coronary obstruction was observed. No moderate/severe paravalvular leakage, new onset conduction disturbance, and new permanent pacemaker implantation were noted. At 30-day follow-up, mean aortic valve gradient was 6.9 ± 1.7 mmHg and mean indexed aortic valve area was 0.95 ± 0.16 cm2 /m2 . Prosthetic valve performance was stable at 12-month follow-up. No severe prosthesis patient mismatch was documented at any time point. No in-hospital, 30-day, and 12-month mortality were observed. The median follow-up was 711 days (IQR 547-803 days), and no patient was lost to follow-up. Conclusions Our preliminary experience suggests favorable safety and efficacy of TAVR utilizing self-expandable THV with intentional down-sizing in patients with severe AS and small SOV in a mid-term follow-up.Problem Contraceptive hormones are systemically active, potent, and likely to invoke biological responses other than known fertility regulation impacts. We hypothesized that initiation of depot medroxyprogesterone acetate (DMPA) would increase genital HIV-target-cells and soluble immune mediators compared with baseline and initiation of other contraceptive methods. Method of study We collected cervical cytobrushes and cervicovaginal fluid from healthy Zimbabwean women aged 18-34 to assess immune cell populations, cytokines, and innate anti-HIV activity at baseline and after 30, 90, and 180 days use of DMPA (n = 38), norethisterone enanthate (n = 41), medroxyprogesterone acetate/estradiol cypionate (n = 36), levonorgestrel implant (n = 43), etonogestrel implant (n = 47), or copper intrauterine device (Cu-IUD) (n = 45). Cells were quantified by flow cytometry, cytokines were detected by multiplex assays, and innate anti-HIV activity was assessed by in vitro HIV challenge. click here Results Compared to baseline, the numbencluding DMPA, did not increase cervical HIV target cells or inflammation. Clinical Trial Number NCT02038335.Background The rate of premature greying, referred to as canities, varies among populations and effective treatments are lacking.However, few studies at the molecular level have been reported. Objectives Comparing lipid profiles of individuals with premature canities and healthy volunteers to explore the mechanism of premature canities. Methods Ultra performance liquid chromatography/quadrupole time-of-flight mass spectrometry(UPLC-QTOF-MS) was used to detect lipids in the hair follicle root. Multivariate data analysis wasused to show lipid changes in follicle roots. Results We identified lipids in the hair follicle root that differ between black and white hair and analysed key lipids contributing to white hair development. We divided the samples into three groups PC-WH(Premature canities-White hair), PC-PH(Premature canities-Pigmented hair), Control-PH(Pigmented hair).Phosphatidylethanolamine(PE), phosphatidylcholine(PC), vitamin D3 (VD3), and cholesterol in Control-PHwere higher than those in PC-WH. Sphingomyelin (SP), phosphatidic acid (PA), VD3, and diglyceride (DG) were lower in PC-WH than inPC-PH. Levels of VD3 were highest inControl-PH, gradually decreased as theseverityof PC-PH increased, and were lowest in PC-WH. Conclusion There are7 main class candidate compounds involved inthe generation of white hair. VD3showeda substantial decrease in white hair and was a potential targetfor further studies ofpremature canities.Developing a novel strategy to synthesis photoresponsive polymers is of significance owing to their potential applications. We report a photoindiced strain-assisted synthesis of main-chain stiff-stilbene polymers using ring-opening metathesis polymerization (ROMP) by activating a macrocyclic π-bond connected to a stiff-stilbene photoswitch via a linker. Since the linker acts as an external constraint, the photoisomerization to the E-form leads to the stiff-stilbene being strained and thus reactive to ROMP. The photoisomerization of E-form to Z-form was investigated using time-dependent NMR studies and UV/Vis spectroscopy. The DFT calculation showed that the E-form was less stable due to a lack of planarity. By the internal strain developed due to the linker constraint through photoisomerization, the E-form underwent ROMP by a second generation Grubbs catalyst, while Z-form did not undergo polymerization under similar conditions. The MALDI-TOF spectrum of E-form after polymerization showed the presence of oligomers > 5.2 kDa.Aims Many tachy-brady syndrome (TBS) patients, are implanted a permanent pacemaker (PPM) to allow continuation of anti-arrhythmic drug (AAD) therapy to maintain sinus rhythm. Many of these PPM's are implanted as a preventive measure, in absence of symptomatic bradycardia. Our primary aim was to evaluate pacing use among these patients and find predictors for PPM use. Our secondary aim was to appreciate the portion of these patients who progress to permanent atrial fibrillation (AF). Methods Retrospective study of TBS patients implanted a PPM as preventive measure, dividing cases into defined categories regarding highest percent atrial and ventricular pacing documented in PPM clinic visits during 3 year follow-up (F/U) period. Patients' baseline characteristics and AAD therapy were compared between cases with a major (>90%) pacing use and cases with 50%) pacing use and 58% had a major pacing use. Significant association was found between pre-implant severe sinus bradycardia ( less then 40 bpm), first degree atrioventricular block and amiodarone treatment to major pacing use on univariate analysis and severe sinus bradycardia was significantly associated with major pacing on multivariate analysis as well.
