H19 and its derived exosomal miR-675 from NHEKs, which has been proven relevant to melanogenesis, were significantly upregulated after irradiation. Furthermore, H19 knockdown and miR-675 inhibition in NHEKs could attenuate the inhibition effect of 585 nm LEDs on melanogenesis. CONCLUSIONS This study demonstrated that 585 nm LEDs could inhibit melanogenesis via the up-regulation of H19 and its derived exosomal miR-675 from NHEKs, which was considered as a novel paracrine factor in regulating melanogenesis. The Gerard W. Ostheimer Lecture presented at the annual meeting of the Society of Obstetric Anesthesia and Perinatology (SOAP) is a one-year summary of the literature published in domains of interest to anesthesiologists who manage and care for obstetric patients. One individual is asked to review the literature and present the lecture. This manuscript summarizes aspects of the Gerard W. Ostheimer Lecture presented at the 2019 SOAP meeting; the relevant literature from 2018 was summarized. WNK463 research buy The topics included in this review are maternal morbidity, antibiotic prophylaxis, anaphylaxis, the Lancet series on increasing cesarean delivery rates, the Robson Ten-Group Classification System, pelvic floor disorders, timing of delivery in nulliparous women, placenta accreta disorders, anesthesia for cesarean delivery, labor analgesia (including parturients with thrombocytopenia and tattoos, and epidural maintenance with the programmed intermittent epidural bolus technique), ultrasound use in obstetric anesthesia, and drugs in pregnancy. BACKGROUND The relationship between pain and mortality risk has not been well established. AIMS This study aimed to assess the possible association between a chief complaint of pain and in-hospital mortality. DESIGN Retrospective cohort study using 11-year hospital administrative data. SETTING Southwest Hospital of Third Military Medical University (Chongqing, China). PARTICIPANTS A total of 645,998 adult inpatients admitted without department limitation between January 1, 2003, and December 31, 2013. METHODS Information on the chief complaint at admission was obtained, and the main outcome measure was in-hospital mortality. RESULTS The crude overall in-hospital mortality rate for patients admitted with chief complaint of pain was 958 (3.9%), which was significantly lower than that of patients without pain (1,970, 4.9%). The risk of hospital death for inpatients admitted with pain was 21% lower compared to inpatients admitted without pain (p  less then  .001). Female patients with a chief complaint of pain had a lower risk of in-hospital mortality (p  less then  .001) compared with male patients (p  less then  .001). When stratified by location of pain, patients with chest pain had a significantly higher risk of in-hospital mortality compared with those without complaint of pain (p  less then  .001), whereas for patients with a chief complaint of waist, abdominal, limb, or joint pain, the risk of hospital death was lower compared with cases without pain. CONCLUSIONS The present study suggested that inpatients admitted with a chief complaint of pain might have a significantly lower risk of in-hospital mortality compared with those admitted without a chief complaint of pain. BACKGROUND Chronic low back pain (CLBP) prevalence is higher among women and those with low socioeconomic status. Without adequate self-efficacy and subsequent self-management, patients gradually develop chronic multisite pain after one year of having CLBP alone. AIM This study investigated the predictors of self-efficacy and multisite pain among adult, economically disadvantaged women, where pain prevalence is higher. DESIGN Cross-sectional, descriptive study. SETTING Pain management center. SUBJECTS Participants (n = 50) with primary diagnosis of chronic low back pain. METHODS After Institutional Review Board approval, data collection was conducted using valid and reliable instruments measuring several variables. Controlling for age and race, multiple linear regression was used for analyses. RESULTS AND CONCLUSIONS For all predictors of self-efficacy, a significant regression equation was identified (p less then .01) with R2 of .413 and variance of .643. Pain catastrophizing was a significant individual pr prompt intervention, facilitate better pain response to treatments, and minimize further disability. Copper (Cu) is an essential element regulated by four genes (hCTR1, hATOX1, hATP7A, and hATP7B in humans and zctr1, zatox1, zatp7a, and zatp7b in zebrafish) in copper uptake, distribution, and transport in animal cells. Zebrafish (Danio rerio) shows a higher endogenous ratio of zatp7a to zatp7b in the liver, is relatively intolerant to copper ions and has a different zatp7a and zatp7b expression patterns in different organs. As high-affinity copper transporters, both zctr1 and hCTR1 increased copper toxicity, whereas hATOX1 and zatox1 slightly reduced copper toxicity in HepG2 cells after copper administration for 24 h. The transfected zatp7b functioned in HepG2 cells as effectively as hATP7B after both 24-h and 96-h copper exposure, but zatp7a failed to function in HepG2 cells as effectively as hATP7A. Our findings suggest that ATP7A dysfunction would increase cytotoxicity in the liver; the reason for zebrafish's copper intolerance could be the bulk dysfunction and abnormal localization of zATP7A. Tai-Chi (TC) practice has been increasingly used to prevent falls in older adults. However, the biomechanical mechanisms underlying the effects of TC practice on fall risk among older adults remain unanswered. The objective of this pilot study was to examine how TC gait biomechanically impacts the human body in terms of dynamic gait stability and lower limb muscle strength in comparison with regular walking gait. Ten healthy adults performed five trials of TC gait following three to seven trials of regular walking. Full body kinematics and kinetics were collected, and then dynamic gait stability and lower limb joint moments were determined. During TC gait, individuals were less stable, moved more slowly and experienced a larger mediolateral movement in comparison with regular walking gait. The peak moment at the ankle joint on the sagittal and transverse planes, at the knee joint on all three planes, and at the hip joint on the frontal plane was significantly different when performing TC gait than during regular gait.
