Who Benefits from Oncoplastic Surgical Techniques?

Breast-conserving therapy, which includes wide local excision of the tumor followed by irradiation, has become a standard treatment option for women with early-stage invasive breast cancer. The potential advantages of conservative breast surgery include the minor outpatient nature of the procedures, lower incidence of post-operative pain and complications, preservation of the breast and nipple areolar complex, and shorter delay to adjuvant therapy. However, not all patients are optimal candidates for breast-conserving procedures. Oncoplastic techniques combine the removal of breast cancer tumors in combination with either local volume replacement techniques to correct small defects, or by immediate reconstruction of larger defects using techniques of plastic surgery with or without contralateral breast procedures for symmetry. Therefore, oncoplastic techniques offer the potential to perform a wider excision of the tumor with an improved cosmetic result, thus potentially increasing the eligible pool for breast conservation.     

Racism,Health Status,and Birth Outcomes: Results of a Participatory Community-Based Intervention and Health Survey

Many community-based participatory research (CBPR) partnerships address social determinants of health as a central consideration. However, research studies that explicitly address racism are scarce in the CBPR literature, and there is a dearth of available community-generated data to empirically examine how racism influences health disparities at the local level. In this paper, we provide results of a cross-sectional, population-based health survey conducted in the urban areas of Genesee and Saginaw Counties in Michigan to assess how a sustained community intervention to reduce racism and infant mortality influenced knowledge, beliefs, and experiences of racism and to explore how perceived racism is associated with self-rated health and birth outcomes. We used ANOVA and regression models to compare the responses of intervention participants and non-participants as well as African Americans and European Americans (N = 629). We found that intervention participants reported greater acknowledgment of the enduring and differential impact of racism in comparison to the non-intervention participants. Moreover, survey analyses revealed that racism was associated with health in the following ways: (1) experiences of racial discrimination predicted self-rated physical health, mental health, and smoking status; (2) perceived racism against one’s racial group predicted lower self-rated physical health; and (3) emotional responses to racism-related experiences were marginally associated with lower birth-weight births in the study sample. Our study bolsters the published findings on perceived racism and health outcomes and highlights the usefulness of CBPR and community surveys to empirically investigate racism as a social determinant of health.     

Identification of reptilian and amphibian blood meals from mosquitoes in an eastern equine encephalomyelitis virus focus in central Alabama

Uranotaenia sapphirina, Culex erraticus, and Cx. peccator were collected in an enzootic eastern equine encephalomyelitis (EEE) virus focus in central Alabama (Tuskegee National Forest) from 2001 to 2003 and analyzed for virus as well as host selection. EEE virus was detected in each species every year except 2003, when pools of Cx. peccator were negative. Most (97%) of the 130 Cx. peccator blood meals identified were from ectothermic hosts; 3% were from birds. Among blood meals from reptiles (approximately 75% of the total), 81% were from Agkistrodon piscivorus (cottonmouth); all amphibian blood meals (approximately 25%) were from Rana spp. with > 50% taken from the bullfrog R. catesbeiana. Host identifications were made from 131 of 197 Cx. erraticus, but only 3 (2%) were derived from ectothermic species. Identification of Ur. sapphirina blood meals proved difficult and only 2 of 35 hosts were determined. Both were from R. catesbeiana. Ectothermic species are possible EEE virus reservoirs in the southeastern United States where species such as Cx. peccator and Ur. sapphirina occur with large, diverse reptilian, amphibian, and avian populations such as those at the Tuskegee site.     

Sleep Mediates the Association Between PTSD Symptoms and Chronic Pain in Youth

Symptoms of post-traumatic stress disorder (PTSS) and chronic pain have been shown to co-occur at high rates in adolescents and this co-occurrence is linked to worse pain and quality of life. Sleep disturbance has been posited as a mechanism underlying this co-occurrence in conceptual models of mutual maintenance. This study examined the mediating role of sleep in the relationship between PTSS and pain in youth (aged 10–17 years) with chronic pain. Ninety-seven participants completed measures of PTSS, pain (intensity and interference), anxiety symptoms, and sleep quality, in addition to demographic characteristics. Mediation models were conducted. Findings revealed that, over and above the influence of associated demographic characteristics (age, race) and anxiety symptoms, sleep quality partially mediated the relationships between PTSS and pain intensity and interference for youth with chronic pain. Specifically, higher levels of PTSS was linked to higher levels of pain intensity and pain interference, and these relationships were partially explained by poor sleep quality. Findings highlight the potential mechanistic role of sleep in explaining the co-occurrence of chronic pain and PTSS and suggest sleep might be an important target in future interventions.
