Violation of pseudospin symmetry in nucleon-nucleus scattering: exact relations

An exact determination of the size of the pseudospin symmetry violating part of the nucleon-nucleus scattering amplitude from scattering observables is presented. The approximation recently used by Ginocchio turns out to underestimate the violation of pseudospin symmetry. Nevertheless the conclusion of a modestly broken pseudospin symmetry in proton-208Pb scattering at EL=800MeV remains valid.Comment: 8 pages, 2 figure

Urban women's socioeconomic status, health service needs and utilization in the four weeks after postpartum hospital discharge: findings of a Canadian cross-sectional survey

<p>Abstract</p> <p>Background</p> <p>Postpartum women who experience socioeconomic disadvantage are at higher risk for poor health outcomes than more advantaged postpartum women, and may benefit from access to community based postpartum health services. This study examined socioeconomically disadvantaged (SED) postpartum women's health, and health service needs and utilization patterns in the first four weeks post hospital discharge, and compared them to more socioeconomically advantaged (SEA) postpartum women's health, health service needs and utilization patterns.</p> <p>Methods</p> <p>Data collected as part of a large Ontario cross-sectional mother-infant survey were analyzed. Women (N = 1000) who had uncomplicated vaginal births of single 'at-term' infants at four hospitals in two large southern Ontario, Canada cities were stratified into SED and SEA groups based on income, social support and a universally administered hospital postpartum risk screen. Participants completed a self-administered questionnaire before hospital discharge and a telephone interview four weeks after discharge. Main outcome measures were self-reported health status, symptoms of postpartum depression, postpartum service needs and health service use.</p> <p>Results</p> <p>When compared to the SEA women, the SED women were more likely to be discharged from hospital within the first 24 hours after giving birth [OR 1.49, 95% CI (1.01–2.18)], less likely to report very good or excellent health [OR 0.48, 95% CI (0.35–0.67)], and had higher rates of symptoms of postpartum depression [OR 2.7, 95% CI(1.64–4.4)]. No differences were found between groups in relation to self reported need for and ability to access services for physical and mental health needs, or in use of physicians, walk-in clinics and emergency departments. The SED group were more likely to accept public health nurse home visits [OR 2.24, 95% CI(1.47–3.40)].</p> <p>Conclusion</p> <p>Although SED women experienced poorer mental and overall health they reported similar health service needs and utilization patterns to more SEA women. The results can assist policy makers, health service planners and providers to develop and implement necessary and accessible services. Further research is needed to evaluate SED postpartum women's health service needs and barriers to service use.</p

Sexual Assault History May Moderate Posttraumatic Cognition and Posttraumatic Stress Among Trauma-Exposed Sexual Minority Women

Sexual minority women (SMW) are highly vulnerable to trauma exposure and posttraumatic stress disorder (PTSD) symptoms following trauma exposure. Negative posttraumatic cognitions (i.e., negative cognitions about self, word, and self-blame following trauma exposure) are hypothesized to exacerbate and maintain the relationship between trauma exposure and PTSD symptoms. Posttraumatic cognitions are particularly important to examine in relation to PTSD symptoms among trauma exposed SMW given their elevated risk for trauma exposure and PTSD. It is also important to understand whether the strength of this relationship differs as a function of trauma type to elucidate potentially differential pathways for risk by trauma type in this population. The current study explored whether trauma type (sexual assault vs. non-sexual trauma) moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity among a sample of trauma-exposed SMW. Participants were SMW (n = 516) users of online survey platform, Prolific. Data were collected via 20-minute online survey. Results indicated that trauma type moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity, such that the relationship was stronger among those who had experienced at least one sexual assault in their lifetime. Results suggest that negative posttraumatic cognitions may be more strongly related to PTSD symptom severity among SMW who have experienced at least one sexual assault. Notably, this difference was in magnitude only, as the posttraumatic cognition – PTSD symptom relationship remained significant among non-sexual trauma survivors. Negative posttraumatic cognitions may be an especially relevant treatment target among SMW survivors of sexual assault
