RESUMO
We prospectively collected PROMIS©25 and PROMIS©29 surveys in the Sickle Cell Transplant Evaluation of Long Term and Late Effects Registry (STELLAR). Mobility and social participation T-scores were decreased; all other domains were within the norm.
RESUMO
BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HCT) performed in children from human leukocyte antigen (HLA)-identical related donors is associated with very high survival rates and disease-free survival. Patients are exposed to gonadotoxic alkylating agents or irradiation in the HCT conditioning regimen. Consequently, infertility is a major long-term complication of HCT for sickle cell disease (SCD). We sought to understand how caregivers perceive the risk of infertility from HCT, how they perceive the options for fertility preservation, and how this risk perception impacted their decision-making to pursue HCT. PROCEDURES: We conducted qualitative interviews with primary caregivers after a consultation for HCT for SCD. Data were analyzed using descriptive qualitative analysis. RESULTS: We interviewed 19 primary caregivers who had attended a consultation with an HCT physician (female, age 25-59 [median 39] years). Eleven participants reported that their child had an available HLA-matched donor. Analysis revealed that (i) mothers were worried about death and graft-versus-host disease from HCT, more than about the risk of infertility; (ii) parents have a realistic understanding of the risk of infertility after HCT and take it into consideration in decision-making; (iii) parents report multiple barriers to fertility preservation. CONCLUSION: For parents actively considering HCT for their child with SCD, the risk of infertility while important was not a barrier to pursuing HCT. Inconvenience and invasiveness of fertility preservation procedures are some of the barriers to pursuing fertility preservation for their child. Future research must aim at addressing these barriers to fertility preservation.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a treatment option with curative intent for patients with transfusion dependent thalassemia (TDT) but its application is limited by the lack of suitable donors and acceptability due to the related morbidity/mortality. Transplantation of autologous genetically modified hematopoietic cells, gene therapy (GT) is emerging as a promising treatment option for TDT as it eliminates graft versus host disease (GVHD) and need for immunosuppression. Early results of GT suggest that many, but not all patients achieve transfusion independence after the procedure. There is little information about the acceptability of GT in patients with TDT. We sought to examine patient/family knowledge about GT in TDT and to examine factors that influence decision-making about this therapy. METHODS: Parents of children with TDT and adults with TDT were who provided informed consent underwent semi-structured interviews to understand patient/family knowledge and decision-making regarding GT in TDT. Transcribed interviews were coded and the data was examined for emerging themes using a combination of thematic and content analysis. RESULTS: Twenty-five study participants with mean age of 38Y (17-52Y) including eight adults living with TDT, and 17 parents of children with TDT underwent semi-structured qualitative interviews. Participant responses coalesced around broad themes related to knowledge of GT, motivating/deterring factors and outcomes. Study participants expressed a desire for 'cure' from thalassemia including transfusion independence, chelation reduction and improved quality of life as motivators for considering GT. Insufficient knowledge about the process, long-term outcomes, safety, and side effects as well as the potential for death/failure of the procedure were deterrents for the consideration GT. Reduction in frequency of transfusions, even without elimination of transfusions was an acceptable outcome of GT for most participants. Participant choice for preferred treatment modality was split between indefinitely continuing transfusions which was familiar to them versus GT which was unfamiliar, and with an uncertain outcome. None of the participants had a matched sibling donor; alternate donor HSCT was the least preferred option in this group. CONCLUSION: There is tempered excitement about GT in patients/families with TDT with a general willingness to accept transfusions reduction as the outcome.

BACKGROUND: Improved outcomes and the availability of clinical trials of hematopoietic cell transplantation (HCT) from alternate donors and genetically modified autologous hematopoietic progenitor cells have expanded the applicability of HCT for sickle cell disease (SCD). To understand the perspective of primary caregivers exploring HCT in the current milieu, we asked the research question "What motivates primary caregivers to decide to consider HCT and to seek, and to attend, an HCT consultation?" PROCEDURES: We conducted qualitative interviews with primary caregivers within one week after a consultation for HCT for SCD. Data were analyzed using open and axial coding stages of grounded theory methodology. RESULTS: We interviewed 29 primary caregivers (26 females, age 29 to 64 [median 42] years). Primary caregivers report of SCD complications in their child included at least one in the last year by 23 (82%), few or none by 8 (28%), and pain on ≥3 days a week by 13 (46%) primary caregivers. Qualitative analysis revealed that primary caregivers, (i) learn about curative options through social networks, social media, and the news media; (ii) seek consultation because of their child's diminished quality of life, recent complications, an imminent major medical decision, or anxiety about future severe complications; and (iii) see gene therapy as a new, less invasive, and more acceptable treatment. CONCLUSION: Primary caregivers of children with SCD learn about HCT through social networks, social and news media, and explore HCT as a means to prevent SCD complications and help their child live a normal life.

AIMS: We performed an assessment to understand perceived decisional needs among those living with sickle cell disease. Additionally, we desired understanding of their preferred methods and quality of learning and sought guidance in development of a web-based patient decision aid. DESIGN: The purpose of this qualitative study was to determine ways patients and caregivers receive education about sickle cell disease and available therapies. We sought to understand preferences for education, quality of current knowledge and information they would like to obtain. METHODS: Recruitment for the initial needs assessment occurred between October 2013 -April 2014. Further recruitment for clarification of internet-based searches occurred between January 2015 -September 2016. We conducted a total of 201 semi-structured qualitative interviews with patients and caregivers. RESULTS: Six themes emerged: healthcare provider education is good but does not meet all the learning needs of the patient/caregiver; patients/caregivers feel a strong desire to seek information about treatment options on their own; adult patients and parents diverged in their core objectives in seeking information: quality of life (QOL) was the major outcome of interest in considering potential treatment options; experience of peers is preferred source for learning about treatment options; and educational needs may be supplemented with a web-based interactive educational tool. CONCLUSION: Patients with sickle cell disease and their caregivers are motivated by a desire to improve QOL in seeking treatment options and use many methods to seek education to supplement what they learn from their healthcare providers and may benefit from the use of a web-based decision aid. Impact Educational needs of patients/caregivers with sickle cell disease were identified and provide the basis to inform the design of educational strategies for them. Nurses and others can assist with learning needs by sharing the website and answering questions that arise.

BACKGROUND: Idiopathic nephrotic syndrome has a relapsing-remitting course in the majority of pediatric patients, demanding vigilant monitoring and self-management. A novel, expert-designed, user-informed mobile application (app), UrApp©, was created to support management tasks, including home urine protein monitoring. METHODS: The UrApp Pilot Study (ClinicalTrials.gov, NCT04075656) is a randomized trial comparing UrApp-supported nephrotic syndrome management with standard-of-care with parallel process evaluation of the intervention delivery. Sixty caregivers of children with newly diagnosed, steroid-sensitive nephrotic syndrome will be randomized 1:1 to UrApp-supported care or standard-of-care. Follow-up will be 1 year, with primary outcomes of adherence to urine monitoring and medications assessed at 6 and 12 months. Secondary outcomes at 6 and 12 months include self-efficacy, quality-of-life, hospitalizations and delayed relapse diagnoses. A mixed-methods approach will evaluate UrApp engagement, use retention, features used, user perceptions, and contextual barriers and facilitators of UrApp use. User behavior will be assessed for relationships to the primary and secondary outcomes. A Stakeholder Committee of volunteer trial participants, clinicians, and engineers will examine the trial results and design a pragmatic UrApp-enhanced nephrotic syndrome intervention with potential for wide implementation. The final UrApp intervention will be tested in a user-centered hybrid effectiveness-implementation trial designed with stakeholder input. DISCUSSION: The UrApp Pilot Study examines the efficacy of a novel app designed specifically for nephrotic syndrome. The protocol involves dual efficacy and process evaluation aims to increase efficiency and incorporates the stakeholders' perspective in formative assessment to inform intervention redesign and the design of a future user-centered trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04075656. Registered on September 2, 2019, https://clinicaltrials.gov/ct2/show/NCT04075656.

BACKGROUND: There is a limited understanding of the patient and family experience of Chronic Transfusion Therapy (CTT) for prevention of complications of Sickle Cell Disease (SCD). We sought to understand patient and family experience with CTT using qualitative methods. METHODS: Fifteen parents of children < 18 years old and nine children 12-18 years old with SCD who were receiving CTT for > 1 year were interviewed using a semi-structured interview format, and interviews were analyzed using open coding methods. RESULTS: Four themes created a narrative of the patient and family experience of CTT: 1) Burden of CTT, 2) Coping with CTT, 3) Perceived benefits and risks of CTT, and 4) Decision making regarding CTT. Participants reported substantial burden of CTT, including the impact of CTT on daily life and family, distress about venous access, burden of chelation therapy, and anxiety about CTT complications. Participants described how they coped with CTT. Participants reported increased energy, decreased pain, fewer hospitalizations, and stroke prevention with CTT, but also recognized complications of CTT, though awareness was limited in adolescents. Parents described sharing in the informed decision-making process with their healthcare provider about CTT, but adolescent patient participants reported that they were not involved in this process. CONCLUSIONS: CTT is associated with significant patient and family burden. Support from family, healthcare providers and school may help individuals cope with some of this burden. These findings provide the basis for future studies to identify strategies to mitigate the burden of CTT and improve the patient experience with this therapy. Future studies should also systematically assess patient knowledge about the key components of CTT and chelation using quantitative assessments.

BACKGROUND: Hydroxyurea, chronic blood transfusions, and bone marrow transplantation are efficacious, disease-modifying therapies for sickle cell disease but involve complex risk-benefit trade-offs and decisional dilemma compounded by the lack of comparative studies. A patient decision aid can inform patients about their treatment options, the associated risks and benefits, help them clarify their values, and allow them to participate in medical decision making. OBJECTIVE: The objective of this study was to develop a literacy-sensitive Web-based patient decision aid based on the Ottawa decision support framework, and through a randomized clinical trial estimate the effectiveness of the patient decision aid in improving patient knowledge and their involvement in decision making. METHODS: We conducted population decisional needs assessments in a nationwide sample of patients, caregivers, community advocates, policy makers, and health care providers using qualitative interviews to identify decisional conflict, knowledge and expectations, values, support and resources, decision types, timing, stages and learning, and personal clinical characteristics. Interview transcripts were coded using QSR NVivo 10. Alpha testing of the patient decision aid prototype was done to establish usability and the accuracy of the information it conveyed, and then was followed by iterative cycles of beta testing. We conducted a randomized clinical trial of adults and of caregivers of pediatric patients to evaluate the efficacy of the patient decision aid. RESULTS: In a decisional needs assessment, 223 stakeholders described their preferences, helping to guide the development of the patient decision aid, which then underwent alpha testing by 30 patients and 38 health care providers and iterative cycles of beta testing by 87 stakeholders. In a randomized clinical trial, 120 participants were assigned to either the patient decision aid or standard care (SC) arm. Qualitative interviews revealed high levels of usability, acceptability, and utility of the patient decision aid in education, values clarification, and preparation for decision making. On the acceptability survey, 72% (86/120) of participants rated the patient decision aid as good or excellent. Participants on the patient decision aid arm compared to the SC arm demonstrated a statistically significant improvement in decisional self-efficacy (P=.05) and a reduction in the informed sub-score of decisional conflict (P=.003) at 3 months, with an improvement in preparation for decision making (P<.001) at 6 months. However, there was no improvement in terms of the change in knowledge, the total or other domain scores of decisional conflicts, or decisional self-efficacies at 6 months. The large amount of missing data from survey completion limited our ability to draw conclusions about the effectiveness of the patient decision aid. The patient decision aid met 61 of 62 benchmarks of the international patient decision aid collaboration standards for content, development process, and efficacy. CONCLUSIONS: We have developed a patient decision aid for sickle cell disease with extensive input from stakeholders and in a randomized clinical trial demonstrated its acceptability and utility in education and decision making. We were unable to demonstrate its effectiveness in improving patient knowledge and involvement in decision making.

Sickle cell disease (SCD) is one of the most commonly inherited hemoglobin disorders that has a significant impact on quality of life, increased childhood morbidity, and premature mortality. Currently, hematopoietic stem cell transplant (HSCT) is the only treatment with a curative intent. The objective of this study was to determine patients' and caregivers' knowledge of HSCT, the factors influencing the decision to pursue HSCT, their experiences, and the impact of a successful HSCT on their daily living. At Children's Healthcare of Atlanta, we conducted a qualitative study using a semistructured interview guide of patient-caregiver dyads and 2 focus-group sessions of adult long-term survivors of HSCT to elicit key factors in decision making, their experiences with HSCT, and the impact of HSCT. Interviews and focus-group sessions were recorded and transcribed verbatim. Transcripts were coded and analyzed for emerging themes using NVivo 10.0. We enrolled 11 patient-caregiver dyads (n = 6, female patients; n = 10, mothers) in the qualitative interviews and 2 focus groups with 5 (n = 2, females) and 7 (n = 3, females) participants in each group, respectively. Our analysis revealed 3 prominent themes: (1) factors and concerns influencing HSCT decision making; (2) HSCT experiences; and (3) impact of HSCT on daily life. Participants reported that progression of disease-related complications and availability of a matched donor strongly influenced the decision to pursue HSCT. Although patients and caregivers had to deal with the arduous process of HSCT and transplant-related morbidities, participants were satisfied with their decision and expressed no decisional regrets. Decision making for HSCT for patients with SCD is a complex process. Understanding the key influential factors in decision making and the impact HSCT has on these patients and their families will generate crucial insights that can guide the care of future patients and research studies.

BACKGROUND: The entry of calcium ions into mammary gland epithelial cells is one of the least well-understood processes in the transport of calcium into milk during lactation. The store-operated calcium entry channel ORAI1, has been suggested as a potential mechanism for the entry of Ca(2+) into mammary gland epithelial cells from the maternal blood supply during lactation. The down regulation of the canonical ORAI1 activator STIM1 during lactation suggests that other known ORAI activators such as STIM2 and SPCA2 may be important during lactation. RESULTS: Differentiation of HC11 mammary gland epithelial cells was associated with enhanced basal Ca(2+) influx. Silencing of Orai1 abolished this enhancement of Ca(2+) influx. Stim2 had a modest effect on Ca(2+) influx in this in vitro model of lactation, whereas Stim1 and Spca2 silencing had no effect. Despite pronounced increases in Spca2 mRNA during lactation there was no change in the generation of the alternative splice product generated by Mist1, which increases during lactation. CONCLUSIONS: These studies support the hypothesis that lactation is associated with a remodelling of Ca(2+) influx and this is associated with enhancement of basal Ca(2+) influx. This enhanced Ca(2+) influx appears to occur through the calcium channel Orai1.

Laboratory studies show that individuals differ appreciably in the magnitude of their inflammatory responses to acute psychological stress. These individual differences are poorly understood, yet may contribute to variation in stress-associated disease vulnerability. The present study examined the possibility that affective responses to acute stress contribute to these differences. For this purpose, 102 relatively-healthy community volunteers (mean age 50 years; 60% female; 91.2% white) performed an acute stress protocol and measures of affective state and serum levels of the proinflammatory cytokine, interleukin (IL)-6 were collected at the end of a 30-min resting baseline, a 5-min evaluative public speaking task, and a 30-min recovery period. Results of regression analyses, controlling for age, race, gender, menopausal status, and body mass index, revealed a positive association of task-related increases in anger and anxiety with increases in IL-6 (R² change = .08, p = .004; R² change = .08, p = .005, respectively). Further examination showed that these affective responses to the task were independent predictors of change in IL-6. Cardiovascular reactivity to the task did not explain the association. These results suggest that individuals who exhibit angry or anxious responses to acute challenge are more vulnerable to stress-related increases in markers of systemic inflammation, possibly rendering them more susceptible to inflammatory disease.

BACKGROUND: Individuals living with sickle cell disease (SCD) may benefit from a variety of disease-modifying therapies, including hydroxyurea, voxelotor, crizanlizumab, L-glutamine, and chronic blood transfusions. However, allogeneic hematopoietic stem cell transplantation (HCT) remains the only nonexperimental treatment with curative intent. As HCT outcomes can be influenced by the complex interaction of several risk factors, HCT can be a difficult decision for health care providers to make for their patients with SCD. OBJECTIVE: The aim of this study is to determine the acceptability and usability of a prototype decision support tool for health care providers in decision-making about HCT for SCD, together with patients and their families. METHODS: On the basis of published transplant registry data, we developed the Sickle Options Decision Support Tool for Children, which provides health care providers with personalized transplant survival and risk estimates for their patients to help them make informed decisions regarding their patients' management of SCD. To evaluate the tool for its acceptability and usability, we conducted beta tests of the tool and surveys with physicians using the Ottawa Decision Support Framework and mobile health app usability questionnaire, respectively. RESULTS: According to the mobile health app usability questionnaire survey findings, the overall usability of the tool was high (mean 6.15, SD 0.79; range 4.2-7). According to the Ottawa Decision Support Framework survey findings, acceptability of the presentation of information on the decision support tool was also high (mean 2.94, SD 0.63; range 2-4), but the acceptability regarding the amount of information was mixed (mean 2.59, SD 0.5; range 2-3). Most participants expressed that they would use the tool in their own patient consults (13/15, 87%) and suggested that the tool would ease the decision-making process regarding HCT (8/9, 89%). The 4 major emergent themes from the qualitative analysis of participant beta tests include user interface, data content, usefulness during a patient consult, and potential for a patient-focused decision aid. Most participants supported the idea of a patient-focused decision aid but recommended that it should include more background on HCT and a simplification of medical terminology. CONCLUSIONS: We report the development, acceptability, and usability of a prototype decision support tool app to provide individualized risk and survival estimates to patients interested in HCT in a patient consultation setting. We propose to finalize the tool by validating predictive analytics using a large data set of patients with SCD who have undergone HCT. Such a tool may be useful in promoting physician-patient collaboration in making shared decisions regarding HCT for SCD. Further incorporation of patient-specific measures, including the HCT comorbidity index and the quality of life after transplant, may improve the applicability of the decision support tool in a health care setting.
RESUMO
OBJECTIVES: To determine the acceptability, feasibility and safety of yoga for chronic pain in sickle cell disease. DESIGN AND SETTING: In Part A of this two-part study, adolescents with SCD and chronic pain (Group 1) and their parent (Group 2) completed a survey designed to capture pain characteristics, attitudes and practices related to yoga, and potential acceptability of a yoga program. In Part B, the study assessed the feasibility and safety of an instructor-led group yoga program. The study was registered on clinicaltrials.gov (NCT03694548). INTERVENTION: Eight instructor-led group yoga sessions. MAIN OUTCOME MEASURES: Feasibility and safety outcomes were chosen a priori, as follows: 1) Proportion of adolescent patients with SCD and chronic pain approached that consent to participate in Part A, 2) Proportion of adolescent participants enrolled in Part A that consent to participate in Part B, 3) Proportion of participants enrolled in Part B that attend at least 6 of 8 yoga sessions, 4) Proportion of participants enrolled in Part B with an ED visit or a hospitalization for pain within 24 h of completion of each yoga session, 5) Proportion of participants in Part B who complete all study assessments before, and at the end of the yoga program, 6) Adherence to submission of pain diary. RESULTS: The median age of 15 patient participants in Part A was 16 (IQR 14-17), and 14 parents was 43.5 (IQR 42-51). Most participants were female. Most participant responses indicated a positive opinion of yoga. Nine adolescents (60 %) from Part A participated in Part B of the study. The median age of 9 participants in Part B was 17 (IQR 15-18), and 5 of the 9 participants were female (53.3 %). Only one participant was able to attend 3 of the 8 yoga sessions offered, and did not experience any ED visits or hospitalizations following the yoga sessions. None of the other feasibility endpoints were met in this study. CONCLUSIONS: Patients with SCD and chronic pain overall have a positive opinion of yoga, but there are challenges with recruitment and retention of participants in a clinical trial of yoga, and barriers to feasibility of an in-person group yoga intervention.

BACKGROUND & AIMS: Iron has been proposed as influencing the progression of liver disease in subjects with non-alcoholic fatty liver disease (NAFLD). We have previously shown that, in the Hfe-/- mouse model of hemochromatosis, feeding of a high-calorie diet (HCD) leads to increased liver injury. In this study we investigated whether the feeding of an iron deficient/HCD to Hfe-/- mice influenced the development of NAFLD. METHODS: Liver histology was assessed in Hfe-/- mice fed a standard iron-containing or iron-deficient diet plus or minus a HCD. Hepatic iron concentration, serum transferrin saturation and free fatty acid were measured. Expression of genes implicated in iron regulation and fatty liver disease was determined by quantitative real-time PCR (qRT-PCR). RESULTS: Standard iron/HCD-fed mice developed severe steatosis whereas NAS score was reduced in mice fed iron-deficient HCD. Mice fed iron-deficient HCD had lower liver weights, lower transferrin saturation and decreased ferroportin and hepcidin gene expression than HCD-fed mice. Serum non-esterified fatty acids were increased in iron-deficient HCD-fed mice compared with standard iron HCD. Expression analysis indicated that genes involved in fatty-acid binding and mTOR pathways were regulated by iron depletion. CONCLUSIONS: Our results indicate that decreasing iron intake attenuates the development of steatosis resulting from a high calorie diet. These results also suggest that human studies of agents that modify iron balance in patients with NAFLD should be revisited.

BACKGROUND: Medication nonadherence is a public health issue that contributes to poor health outcomes and health-care costs. Factors influencing long-term medication adherence are known; however, little is known about short-course medication adherence. OBJECTIVE: This study examined patient perspectives on adherence and factors that influence adherence to short-course pharmacotherapy in diarrhea-predominant irritable bowel syndrome. METHOD: Twenty-seven participants were interviewed to identify their perceptions of barriers and facilitators to thrice-daily, 14-day rifaximin. RESULTS: Participants were primarily female (89%), aged 18 to 65 years. Sixty-eight percent of interviewees were identified as "low-adherers," meaning the percentage of days with correct daily dosing of rifaximin was <80%. The final coding framework identified social/economic-related (family support and medication expense), system-related (relationship with provider and medication knowledge), condition-related (symptom severity), therapy-related (inconvenient dosing), and patient-related (forgetfulness and busyness of daily life) factors that influenced adherence. CONCLUSION: The resulting patient perspectives highlight a diverse set of factors that influence short-course adherence and the need for tailored interventions that address these various factors resulting in enhanced patient outcomes.
RESUMO
Importance: Bone marrow transplant (BMT) is a potentially curative treatment for sickle cell disease (SCD). Patient and caregiver attitudes toward BMT for SCD and the willingness to accept risks of BMT vary, but these attitudes are not well understood. Objective: To understand patient and caregiver perceptions of and attitudes toward BMT for SCD and decision-making about BMT. Design, Setting, and Participants: Qualitative study of interview transcripts from a convenience sample. Transcripts were from adults with SCD and caregivers of patients with SCD recruited from national and regional SCD conferences, symposia, and sickle cell clinics in 2 cities. Interview transcripts were used from the needs assessment phase to develop a patient-decision aid in 2013 to 2014 (group 1) and from the baseline point in 2015 to 2016 (group 2) of the parent trial, a randomized clinical trial of adults and caregivers of patients with SCD to evaluate the effectiveness of a patient decision aid. Main Outcomes and Measures: Participant perspectives on decision-making regarding BMT for SCD. Results: Fifty-seven transcripts from adults with SCD and 50 transcripts from caregivers of patients with SCD were included. Median (interquartile range [IQR]) age of adults with SCD was 34 (21-50) years in group 1 and 30 (23-38) years in group 2. The median (IQR) age of caregivers was 42.5 (31-52) years in group 1 and 41 (35-46.5) years in group 2. Most transcripts from adults with SCD (75.0% in group 1 and 72.4% in group 2) and caregivers of patients with SCD (76.7% in group 1 and 85.0% in group 2) were from female participants. Bone marrow transplant was perceived as a treatment option associated with serious risks. Reported attitudes toward BMT occurred on a continuum ranging from unfavorable to favorable. Participants reported serious decisional dilemma regarding BMT for SCD. Most participants expressed interest in learning about BMT or curative treatments. Conclusions and Relevance: This qualitative study found a continuum in attitudes toward BMT for SCD and highlights the complexity of decision-making in BMT for SCD. Patients and families with SCD expressed an interest in learning about BMT. Future prospective studies of patient decision-making regarding BMT, especially in the context of emerging curative and novel disease-modifying therapies for SCD, are warranted.

Emerging evidence suggests that acute psychological stress modulates inflammatory competence; however, not all findings are consistent. Gender is one factor that may impact magnitude of response. To explore this possibility, we examined the effects of acute mental stress on lipopolysaccharide-induced production of pro-inflammatory cytokines interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha among a relatively healthy sample of midlife men (n=28) and women (n=34). Blood samples for the assessment of cytokine production were drawn before, immediately after, and 30min following subjects' performance of an evaluative speech task. Relative to baseline evaluations, the speech stressor elicited a significant increase in stimulated production of all 3 pro-inflammatory cytokines, as measured 30min following the end of the task. There were no gender differences in the magnitude of this effect. However, men showed a significant decrease in cytokine production from before to immediately following the stressor, whereas women showed no change across this period. Menopausal status partially accounted for these gender differences, with post-menopausal women displaying greater increases in IL-6 and TNF-alpha production from baseline-to-post-task when compared to men. These data provide further evidence that acute psychological stress primes the immune system to mount larger inflammatory responses and initial support for gender differences in the patterning of stress-related cytokine activity. In addition, this study presents novel evidence that post-menopausal women may be particularly susceptible to stress-related inflammatory responses. The possibility that this contributes to the increased risk of inflammatory disease observed among older women warrants investigation.

Importance: The hallmark of sickle cell disease (SCD) is vaso-occlusive pain that may be acute and episodic or may progress to chronic, persistent pain with unpredictable and disabling exacerbations. Patients with SCD rely on opioids almost exclusively for acute and chronic pain management. Objective: To understand how the current opioid epidemic and subsequent guidelines from the Centers for Disease Control and Prevention are associated with the management of acute and chronic pain for patients with SCD. Design, Setting, and Participants: Qualitative study using semistructured interview guides. Interviews 1 hour or longer were conducted over the telephone. Participants were adults (aged ≥18 years) diagnosed with SCD who experienced pain on 3 or more days per week recruited from national SCD conferences, symposiums, and 2 sickle cell clinics. Open coding analysis facilitated thematic analysis of interview transcripts. Data collection took place from May 2017 to June 2018. Main Outcomes and Measures: Participant perspective of any changes to their pain management associated with the 2016 guidelines from the Centers for Disease Control and Prevention. Results: The 15 adults interviewed had a median (range) age of 32 (21-52) years; 13 (87%) were female; and all were of African American race/ethnicity. Participants reported that recently their opioid prescriptions had become more restrictive, were more closely monitored, and were increasingly difficult to fill in pharmacies. Participants also described increased stigmatization about opioid use and that their medical care was being affected by the physician's exclusive focus on reducing pain medication use. There was an emerging interest among adult patients in the consideration of the use of alternative therapies, including marijuana, to manage pain. Conclusions and Relevance: These findings suggest that from the perspective of adults living with SCD, the opioid epidemic may have negatively affected patients' care by increasing barriers to opioids. Patients reported decreased opioid dosing, increased stigmatization regarding opioid use, physician preoccupation with opioid dosage interfering with comprehensive care, and lack of access to alternative therapies.

Acute, intermittent vaso-occlusive pain is the hallmark of sickle cell disease (SCD) and is associated with substantial morbidity and impaired quality of life (QOL). The subgroup of adults with SCD who transition from recurrent, acute pain to chronic, persistent pain have even greater QOL impairment and higher rates of healthcare utilization. Self-management is central to SCD management; however, its role in chronic pain management is not established. This qualitative study was conducted to answer the following research questions: (1) What is the chronic pain experience of adults with SCD? (2) What self-management strategies do adults with SCD use for chronic pain? and (3) Do adults with SCD have any needs in the self-management of chronic pain? Eighteen Black adults with SCD completed a demographics questionnaire and an interview. The majority of the participants were 21-30 years of age (mean 33.5, SD 7.6), female (61.1%), employed at least part-time (61.1%), single/never married (72.2%), and had a SCD type of sickle cell anemia (55.5%). Interview analysis revealed three major themes: (1) the chronic pain experience; (2) strategies for managing chronic pain; and (3) challenges and needs in managing chronic pain. Study findings can be used to support chronic pain management among adults with SCD. Further research is needed to devise and implement effective strategies for the prevention and management of chronic SCD pain.

BACKGROUND: SRY is the pivotal gene initiating male sex determination in most mammals, but how its expression is regulated is still not understood. In this study we derived novel SRY 5' flanking genomic sequence data from bovine and caprine genomic BAC clones. RESULTS: We identified four intervals of high homology upstream of SRY by comparison of human, bovine, pig, goat and mouse genomic sequences. These conserved regions contain putative binding sites for a large number of known transcription factor families, including several that have been implicated previously in sex determination and early gonadal development. CONCLUSION: Our results reveal potentially important SRY regulatory elements, mutations in which might underlie cases of idiopathic human XY sex reversal.
