    Deterioration in movement and posture often occurs with aging. Yet there may be approaches to movement training that can maintain posture and movement coordination patterns as we age. The Alexander Technique is a non-exercise-based approach that aims to improve everyday movement and posture by increasing awareness and modulating whole-body postural muscle activity. This study assessed whether nineteen 55–72-year-old Alexander Technique teachers showed different posture and movement coordination patterns than twenty age-matched controls during a standing and walking protocol using 3D inertial sensors. During upright stance, Alexander Technique teachers showed lower centroidal sway frequency at the ankle (p = .04) and lower normalized jerk at the sternum (p = .05) than controls. During gait, Alexander Technique teachers had more symmetrical gait cycles (p = .04), more symmetrical arm swing velocity (p = .01), greater arm swing velocity (p < .01), greater arm swing range of motion (p = .02), and lower range of acceleration of the torso in the frontal plane (p = .03) than controls. Smoother control of upright posture, more stable torso motion, and less restrained arm mobility suggest that Alexander Technique training may counter movement degradation that is found with aging. Results highlight the important balance between mobility and stability within the torso and limbs

    Forest Cover Associated with Improved Child Health and Nutrition: Evidence from the Malawi Demographic and Health Survey and Satellite Data

    Healthy forests provide human communities with a host of important ecosystem services, including the provision of food, clean water, fuel, and natural medicines. Yet globally, about 13 million hectares of forests are lost every year, with the biggest losses in Africa and South America. As biodiversity loss and ecosystem degradation due to deforestation continue at unprecedented rates, with concomitant loss of ecosystem services, impacts on human health remain poorly understood. Here, we use data from the 2010 Malawi Demographic and Health Survey, linked with satellite remote sensing data on forest cover, to explore and better understand this relationship. Our analysis finds that forest cover is associated with improved health and nutrition outcomes among children in Malawi. Children living in areas with net forest cover loss between 2000 and 2010 were 19% less likely to have a diverse diet and 29% less likely to consume vitamin A-rich foods than children living in areas with no net change in forest cover. Conversely, children living in communities with higher percentages of forest cover were more likely to consume vitamin A-rich foods and less likely to experience diarrhea. Net gain in forest cover over the 10-year period was associated with a 34% decrease in the odds of children experiencing diarrhea (P5.002). Given that our analysis relied on observational data and that there were potential unknown factors for which we could not account, these preliminary findings demonstrate only associations, not causal relationships, between forest cover and child health and nutrition outcomes. However, the findings raise concerns about the potential short- and long-term impacts of ongoing deforestation and ecosystem degradation on community health in Malawi, and they suggest that preventing forest loss and maintaining the ecosystems services of forests are important factors in improving human health and nutrition outcomes

    Gender Differences in Modifying Lumbopelvic Motion during Hip Medial Rotation in People with Low Back Pain

    Reducing increased or early lumbopelvic motion during trunk or limb movements may be an important component of low back pain treatment. The ability to reduce lumbopelvic motion may be influenced by gender. The purpose of the current study was to examine the effect of gender on the ability of people with low back pain to reduce lumbopelvic motion during hip medial rotation following physical therapy treatment. Lumbopelvic rotation and hip rotation before the start of lumbopelvic rotation were assessed pre- and posttreatment for 16 females and 15 males. Both men and women decreased lumbopelvic rotation and completed more hip rotation before the start of lumbopelvic rotation post-treatment compared to pre-treatment. Men demonstrated greater lumbopelvic rotation and completed less hip rotation before the start of lumbopelvic rotation than women both pre- and post-treatment. Both men and women reduced lumbopelvic motion relative to their starting values, but, overall, men still demonstrated greater and earlier lumbopelvic motion. These results may have important implications for understanding differences in the evaluation and treatment of men and women with low back pain

    The purpose of this study was to evaluate the relationship between postoperative abdominal incision problems and opening subcutaneous tissues with electrocautery or scalpel. Women scheduled for elective abdominal hysterectomy who gave informed consent were randomly assigned to subcutaneous abdominal wall tissue incision by electrocautery or scalpel. Postoperative abdominal wound problem diagnoses included seroma, hematoma, infection, or dehiscence without identifiable etiology. Fifteen of 380 women (3.9%) developed a wound problem; six had scalpel and nine had electrosurgical subcutaneous incisions (P = 0.4). Thicker subcutaneous tissues (P = 0.04) and concurrent pelvic infection (P < 0.001) were significant risk factors for postoperative wound problems. Only two women (0.5%) developed an infection. We conclude that the method of subcutaneous tissue incision was unrelated to the development of postoperative abdominal incision problems in 380 women undergoing elective abdominal hysterectomy

    The inclusion of Persistent Complex Bereavement Disorder (PCBD) in the DSMâ 5 appendix signifies a call for research regarding the distinguishing features and clinical utility of proposed PCBD criteria. Rigorously constructed tools for assessing PCBD are lacking, especially for youth. This study evaluated the validity and clinical utility of the PCBD Checklist, a 39â item measure designed to assess PCBD criteria in youth aged 8 to18 years. Test construction procedures involved: (a) reviewing the literature regarding developmental manifestations of proposed criteria, (b) creating a developmentally informed item pool, (c) surveying an expert panel to evaluate the clarity and developmental appropriateness of candidate items, (d) conducting focus groups to evaluate the comprehensibility and acceptability of items, and (e) evaluating psychometric properties in 367 bereaved youth (Mage = 13.49, 55.0% female). The panel, clinicians, and youth provided favorable content validity and comprehensibility ratings for candidate items. As hypothesized, youth who met full PCBD criteria, Criterion B (e.g., preoccupation with the deceased and/or circumstances of the death), or Criterion C (e.g., reactive distress and/or social/identity disruption) reported higher posttraumatic stress and depressive symptoms than youth who did not meet these criteria, ηp2 = .07â .16. Youth who met Criterion C reported greater functional impairment than youth who did not, ηp2 = .08â .12. Youth who qualified for the â traumatic bereavement specifierâ reported more frequent posttraumatic stress symptoms than youth who did not, ηp2 = .04. Findings support the convergent, discriminant, and discriminantâ groups validity, developmental appropriateness, and clinical utility of the PCBD Checklist.ResumenValidación de Lista de verificación del Trastorno por Duelo Complejo Persistente (TDCP): Un informe del desarrollo de herramientas de medición para duelo en jóvenesLISTA DE CHEQUEO DE TRASTORNO DE DUELO COMPLEJO PERSISTENTELa inclusión del trastorno de duelo complejo persistente (TDCP en su sigla en español; PCBD en sus siglas en inglés) en el apéndice del DSMâ 5 significa un llamado para investigar en relación a las características distintivas y la utilidad clínica de los criterios propuestos para el TDCP. Se carece de herramientas rigurosamente construidas para evaluar TDCP, especialmente para jóvenes. Este estudio evalúa la validez y utilidad clínica de la lista de verificación de TPCP, una medida con 39 ítems diseñada para medir el criterio de TDCP en jóvenes de edades entre 8 a 18 años. El procedimiento de construcción del test involucró: (a) revisión de la literatura relacionada con manifestaciones desarrolladas del criterio propuesto; (b) creación de un pool de ítems informados para el desarrollo; (c) encuesta a un panel experto para evaluar la claridad y desarrollo apropiado de los ítems; (d) conducir grupos focales para evaluar la compresibilidad y aceptabilidad de los ítems; y (e) evaluación de propiedades psicométricas en 367 jóvenes en proceso de duelo (M edad = 13.49, 55.0% femenino). El panel, los clínicos y los jóvenes en proceso de duelo proveyeron una validez de contenido favorable y rangos de comprensibilidad para los ítems candidatos. Como se hipotetizó, los jóvenes que cumplieron el criterio completo de TDCP, criterio B (ej., preocupación por el fallecido y/o las circunstancias de la muerte) o el criterio C (ej., estrés reactivo y/o perturbación social/identidad) reportaron alto estrés postraumático y síntomas depresivos que los jóvenes que no cumplen este criterio, ηp2 = .07 a .16. Los jóvenes que no cumplieron el criterio C reportaron mayor deterioro funcional que los jóvenes que no lo cumplieron ηp2 = .08 a .12. Los jóvenes que calificaron para el â duelo traumático especificoâ reportaron mayor frecuencia de síntomas de estrés postraumático que jóvenes que no calificaron ηp2 = .04. Los resultados apoyan la validez convergente, discriminante y de grupos discriminante; y el apropiado desarrollo y utilidad clínica de la lista de verificación de TDCP para jóvenes con duelo.æ ½è±¡Validation of the Persistent Complex Bereavement Disorder (PCBD) Checklist: A Developmentallyâ Informed Assessment Tool for Bereaved YouthTraditional Chineseæ¨ é¡ : é© è­ ã æ çº æ §è¤ é å æ é ç¤ ç (PCBD)æª¢æ ¥è¡¨ã :ä¸ å é å° å æ é å° å¹´ã å ·ç ¼å± é ©å æ §ç è© ä¼°å·¥å ·æ ®è¦ : DSMâ 5å ¨é é 裡å å «äº æ çº æ §è¤ é å æ é ç¤ ç (PCBD), å æ  æ å æ é è¦ ç  ç©¶å ¶æ å ºç PCBDæ¨ æº ç ¨ç ¹ç ç ¹å¾µå è ¨åº æ ç ¨ã ç ¹å ¥æ ¯é å° é å° å¹´ç PCBD, æ å ç ®å ä» æ¬ ç¼ºå ´æ ¼è¨­è¨ ç è© ä¼°å·¥å ·ã æ ¬ç  ç©¶æª¢è¦ ã PCBDæª¢æ ¥è¡¨ã ç æ 度å è ¨åº æ ç ¨ã å® å ·å 39å 測é é  ç ®, ç ¨ä»¥è© ä¼°å¹´é½¡ä» ä¹ 8è ³18æ­²ç é å° å¹´ç PCBDã ç·¨å ¶è© ä¼°ç é ç¨ å æ ¬: (ä¸ ) å¯©è¦ æ æ å ºç æ¨ æº å ¨é å¾ ç  ç©¶ç ç ¼å± æ ¸æ ; (äº ) å  æ ç ¼å± æ ¸æ å»ºç« ä¸ å é  ç ®åº«; (ä¸ ) 訪å ä¸ ç¾¤å° æ¥­äººå£«, æª¢è¦ æ å å»ºç« ç è© ä¼°é  ç ®ç æ¸ æ¥ æ §å ç ¼å± é ©å æ §; (å ) ä»¥ç ¦é» å° çµ ç å½¢å¼ , æª¢è¦ è© ä¼°é  ç ®ç å ¯ç è§£æ §å å ¯æ ¥å 度; (äº ) æª¢è¦ 367å å æ é å° å¹´ (Mage = 13.49, 55.0% ç ºå¥³æ §)ç å¿ ç 測é ç ¹è³ªã å° æ¥­å é ã è ¨åº æ²»ç 師å å æª¢è¦ ç å æ é å° å¹´, é ½å° è© ä¼°é  ç ®ç å §å®¹æ 度å å ¯ç è§£æ §ä½ å ºè ¯å¥½è© å ã ä¸ å¦ å 設, å® å ¨ç¬¦å PCBDæ¨ æº , æ 符å æ¨ æº B (å¦ å° æ­»è å /æ å ¶æ­»äº¡æ æ³ é ·æ æ æ ) ã æ æ¨ æº C (å¦ å æ æ §æ ²ç å /æ 社交/èº«ä»½èª å å æ ¾) ç é å° å¹´, æ¯ ä¸ ç¬¦ç é å° å¹´æ è¼ é« æ°´å¹³ç å µå ·å¾ å£ å å æ 鬱ç ç (ηp2 = .07 è ³ .16)ã 符å æ¨ æº Cç é å° å¹´æ¯ ä¸ ç¬¦ç é å° å¹´æ è¼ é« æ°´å¹³ç å è ½å æ (ηp2 = .08 è ³ .12)ã 符å æ ã å µå ·æ §å æ ç ¹å¾µã ç é å° å¹´, æ¯ ä¸ ç¬¦ç é å° å¹´æ è¼ é »ç¹ ç å µå ·å¾ å£ å ç ç (ηp2 = .04)ã çµ æ è­ æ ç ¨ä»¥è© ä¼°å æ é å° å¹´ç ã PCBDæª¢æ ¥è¡¨ã æ å ¯è æ 度ã å ¤å ¥æ 度ã çµ å ¥å ¤å ¥æ 度, 亦æ ç ¼å± é ©å æ §å è ¨åº æ ç ¨ã Simplified Chineseæ  é¢ : éª è¯ ã æ ç»­æ §å¤ æ å æ ¸é ç¢ ç (PCBD)æ£ æ ¥è¡¨ã :ä¸ ä¸ªé 对å æ ¸é å° å¹´ã å ·å å± é å æ §ç è¯ ä¼°å·¥å ·æ ®è¦ : DSMâ 5å ¨é å½ é å å «äº æ ç»­æ §å¤ æ å æ ¸é ç¢ ç (PCBD), å æ  æ 们æ é è¦ ç  ç©¶å ¶æ å ºç PCBDæ  å ç ¬ç ¹ç ç ¹å¾ å ä¸´åº æ ç ¨ã ç ¹å «æ ¯é 对é å° å¹´ç PCBD, æ ä»¬ç ®å ä» æ¬ ç¼ºä¸¥æ ¼è®¾è®¡ç è¯ ä¼°å·¥å ·ã æ ¬ç  ç©¶æ£ è§ ã PCBDæ£ æ ¥è¡¨ã ç æ 度å ä¸´åº æ ç ¨ã å® å ·å¤ 39ä¸ªæµ é é¡¹ç ®, ç ¨ä»¥è¯ ä¼°å¹´é¾ ä» ä¹ 8è ³18å² ç é å° å¹´ç PCBDã ç¼ å ¶è¯ ä¼°ç è¿ ç¨ å æ ¬: (ä¸ ) å®¡è§ æ æ å ºç æ  å å ¨è¿ å¾ ç  ç©¶ç å å± æ °æ ®; (äº ) å  åº å å± æ °æ ®å»ºç« ä¸ ä¸ªé¡¹ç ®åº ; (ä¸ ) è®¿é ®ä¸ ç¾¤ä¸ ä¸ äººå£«, æ£ è§ æ ä»¬å»ºç« ç è¯ ä¼°é¡¹ç ®ç æ¸ æ¥ æ §å å å± é å æ §; (å ) ä»¥ç ¦ç ¹å° ç» ç å½¢å¼ , æ£ è§ è¯ ä¼°é¡¹ç ®ç å ¯ç è§£æ §å å ¯æ ¥å 度; (äº ) æ£ è§ 367å å æ ¸é å° å¹´ (Mage = 13.49, 55.0% ä¸ºå¥³æ §)ç å¿ ç æµ é ç ¹è´¨ã ä¸ ä¸ å ¢é ã ä¸´åº æ²»ç å¸ å å æ£ è§ ç å æ ¸é å° å¹´, é ½å¯¹è¯ ä¼°é¡¹ç ®ç å 容æ 度å å ¯ç è§£æ §ä½ å ºè ¯å¥½è¯ å ã ä¸ å¦ å 设, å® å ¨ç¬¦å PCBDæ  å , æ 符å æ  å B (å¦ å¯¹æ­»è å /æ å ¶æ­»äº¡æ å µé ¿æ æ 忧) ã æ æ  å C (å¦ å åº æ §æ ²ç å /æ 社交/身份认å å æ °) ç é å° å¹´, æ¯ ä¸ ç¬¦ç é å° å¹´æ è¾ é« æ°´å¹³ç å 伤å å å å æ é ç ç ¶(ηp2 = .07 è ³ .16)ã 符å æ  å Cç é å° å¹´æ¯ ä¸ ç¬¦ç é å° å¹´æ è¾ é« æ°´å¹³ç å è ½å æ (ηp2 = .08 è ³ .12)ã 符å æ ã å ä¼¤æ §å æ ¸ç ¹å¾ ã ç é å° å¹´, æ¯ ä¸ ç¬¦ç é å° å¹´æ è¾ é¢ ç¹ ç å 伤å å å ç ç ¶(ηp2 = .04)ã ç» æ è¯ æ ç ¨ä»¥è¯ ä¼°å æ ¸é å° å¹´ç ã PCBDæ£ æ ¥è¡¨ã æ æ± è æ 度ã å ¤å «æ 度ã ç» å «å ¤å «æ 度, 亦æ å å± é å æ §å ä¸´åº æ ç ¨ãPeer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/143677/1/jts22277.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/143677/2/jts22277_am.pd

    Proceedings of the Working Group Session on Fertility Preservation for Individuals with Gender and Sex Diversity

    Full text link
    Children and adolescents with gender and sex diversity include (1) gender-nonconforming and transgender individuals for whom gender identity or expression are incongruent with birth-assigned sex (heretofore, transgender) and (2) individuals who have differences in sex development (DSD). Although these are largely disparate groups, there is overlap in the medical expertise necessary to care for individuals with both gender and sex diversity. In addition, both groups face potential infertility or sterility as a result of desired medical and surgical therapies. The Ann and Robert H. Lurie Children's Hospital of Chicago (Lurie Children's) gender and sex development program (GSDP) provides specialized multidisciplinary care for both transgender and DSD patients. In response to patient concerns that recommended medical treatments have the potential to affect fertility, the Lurie Children's GSDP team partnered with experts from the Oncofertility Consortium at Northwestern University to expand fertility preservation options to gender and sex diverse youth. This article summarizes the results of a meeting of experts across this field at the annual Oncofertility Consortium conference with thoughts on next steps toward a unified protocol for this patient group.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140296/1/trgh.2016.0008.pd

    We conducted a multi-stage, genome-wide association study of bladder cancer with a primary scan of 591,637 SNPs in 3,532 affected individuals (cases) and 5,120 controls of European descent from five studies followed by a replication strategy, which included 8,382 cases and 48,275 controls from 16 studies. In a combined analysis, we identified three new regions associated with bladder cancer on chromosomes 22q13.1, 19q12 and 2q37.1: rs1014971, (P = 8 × 10⁻¹²) maps to a non-genic region of chromosome 22q13.1, rs8102137 (P = 2 × 10⁻¹¹) on 19q12 maps to CCNE1 and rs11892031 (P = 1 × 10⁻⁷) maps to the UGT1A cluster on 2q37.1. We confirmed four previously identified genome-wide associations on chromosomes 3q28, 4p16.3, 8q24.21 and 8q24.3, validated previous candidate associations for the GSTM1 deletion (P = 4 × 10⁻¹¹) and a tag SNP for NAT2 acetylation status (P = 4 × 10⁻¹¹), and found interactions with smoking in both regions. Our findings on common variants associated with bladder cancer risk should provide new insights into the mechanisms of carcinogenesis
