Project description:The severity and impact of acute pain after breast surgery varies markedly among individuals, underlining the importance of comprehensively identifying specific risk factors, including psychosocial and psychophysical traits. In this prospective observational study, women (n = 234) undergoing breast-conserving surgery, mastectomy, or mastectomy with reconstruction completed a brief bedside quantitative sensory testing battery, along with measures of psychosocial characteristics. Postoperative pain severity, impact, and opioid use at 2 weeks were assessed using Brief Pain Inventory and procedure-specific breast cancer pain questionnaires. Moderate-severe average pain (>3/10) was reported by 29% of patients at 2 weeks. Regression analysis of pain outcomes revealed that pain severity was independently predicted by axillary dissection, pre-surgical pain, temporal summation of pain (TSP), (-)positive affect, and behavioral coping style. Pain impact was predicted by age, education, axillary dissection, reconstruction, but also by negative affect and depression scores. Lastly, opioid use was predicted by age, education, axillary dissection, reconstruction, TSP, and reinterpreting coping style. Our findings suggest that, individuals with certain phenotypic characteristics, including high TSP and negative affect, may be at greater risk of significant pain and continued opioid use at 2 weeks after surgery, independent of known surgical risk factors. PERSPECTIVE: We measured differences in the psychosocial and psychophysical processing of pain amongst patients before breast surgery using simple validated questionnaires and brief quantitative sensory testing. Independent of younger age and procedural extent (axillary surgery and reconstruction), affect and greater temporal summation of pain predicted acute postoperative pain and opioid use.

Project description:Background: Numerous studies have focused on the PI3K/AKT/mTOR pathway in estrogen receptor positive (ER) breast cancer (BC), as a linear signal transduction pathway and reported its association with worse clinical outcomes. To gain better insight into the relative contribution of each of the signalling pathways which lie downstream to PI3K (namely AKT and mTOR) to BC outcomes, we have developed a novel in silico approach which assessed the activation of each of these signalling pathways separately. Methods: By analysing gene expression and matched proteomic data in ER-positive patients from the TCGA repository, we developed gene signatures that reflect the level of expression of phosphorylated-Serine473-AKT (pAKT) and phosphorylated-Serine2448-mTOR (p-mTOR) separately, capturing their corresponding level of pathway activation. Using pooled analysis of gene-expression data from over 7,000 patients with ER-positive early BC, we then investigated the association between pathway activation and outcomes. Results: Our analysis revealed that the pAKT pathway activation (as measured by the developed signature) was associated with luminal A BC while the p-mTOR pathway activation was more associated with luminal B BC (Kruskal-Wallis test p<10-10). pAKT pathway activation was significantly associated with better outcomes (multivariable HR, 0.79; 95% CI, 0.74 to 0.85; p=2.5x10-10) whereas p-mTOR pathway activation showed worse outcomes (multivariable HR, 1.1; 95% CI, 1.1 to 1.2; p=9.9x10-4). Similar associations between activation and outcomes were obtained when the analysis was performed in patients who were treated with hormonal therapy. Additionally, pAKT pathway activation predicted better outcomes irrespective of the BC molecular subtypes (luminal A multivariable HR, 0.85; 95% CI, 0.75 to 0.96; p=0.01; luminal B HR, 0.91; 95% CI, 0.83 to 0.99; p=0.033). pAKT pathway activation was associated with PIK3CA mutations (p=0.0001) while p-mTOR pathway activation was associated with p53 mutations (p=0.04). Finally, we show that pAKT pathway activation was associated with less response to Everolimus. Conclusions: Our data show that pAKT and p-mTOR pathway activation have differing impact on prognosis and suggest that they are not linearly connected in luminal breast cancers. These findings add to our understanding of signalling through the PI3K pathway and could have important implications for the treatment of luminal BC.

Project description:OBJECTIVES:Although detecting breast cancer at an early stage through screening has been clearly shown to be an effective strategy, the screening participation rate in China remains low. This systematic review sought to synthesise the current evidence to identify factors associated with breast cancer screening participation among women in mainland China. DESIGN:This study was a systematic review. DATA SOURCES:Studies were collected from PubMed, PsycINFO, CINAHL, EMBASE and three major Chinese databases, specially China National Knowledge Infrastructure, Chongqing VIP and Wanfang Data. ELIGIBILITY CRITERIA:All included papers were original research studies with a longitudinal or cross-sectional study design that considered associated factors of breast cancer screening participation among women in mainland China. DATA EXTRACTION AND SYNTHESIS:Study selection, data extraction and quality assessment were conducted independently by two reviewers, involving a third to help reach a consensus when necessary. Primary outcomes of interest included factors associated with breast cancer screening participation. RESULTS:A total of 19 studies were included in this review. Based on these studies, geographical region, a personal history of breast disease, past screening behaviours for breast disease, physical examination and the availability of medical specialists/equipment for breast examination were consistently associated with participation in breast cancer screening, while residential area, ethnicity and attitude towards breast cancer screening appeared to be associated with participation in breast cancer screening. There were additionally some factors with even more limited evidence with which to ascertain their association with screening participation. CONCLUSIONS:There exists a wide range of factors that influence breast cancer screening participation in mainland China. These findings could help to inform future research and policy efforts.

Project description:PURPOSE:To report reconstructive outcomes of patients treated with post-mastectomy intensity modulated proton therapy (IMPT) following immediate breast reconstruction (IBR). MATERIALS AND METHODS:Consecutive women with breast cancer who underwent implant-based IBR and post-mastectomy IMPT were included. Clinical characteristics, dosimetry, and acute toxicity were collected prospectively and reconstruction complications retrospectively. RESULTS:Fifty-one women were treated between 2015 and 2017. Forty-two had bilateral reconstruction with unilateral IMPT. The non-irradiated contralateral breasts served as controls. Conventional fractionation (median 50?Gy/25?fractions) was administered in 37 (73%) and hypofractionation (median 40.5?Gy/15?fractions) in 14 (27%) patients. Median mean heart, ipsilateral lung V20Gy, and CTV-IMN V95% were 0.6?Gy, 13.9%, and 97.4%. Maximal acute dermatitis grade was 1 in 32 (63%), 2 in 17 (33%), and 3 in 2 (4%) patients. Surgical site infection (hazard ratio [HR] 13.19, 95% confidence interval [CI] 1.67-104.03, p?=?0.0012), and unplanned surgical intervention (HR 9.86, 95% CI 1.24-78.67, p?=?0.0068) were more common in irradiated breasts. Eight of 51 irradiated breasts and 2 of 42 non-irradiated breasts had reconstruction failure (HR 3.59, 95% CI 0.78-16.41, p?=?0.084). Among irradiated breasts, hypofractionation was significantly associated with reconstruction failure (HR 4.99, 95% CI 1.24-20.05, p?=?0.024), as was older patient age (HR 1.14, 95% CI 1.05-1.24, p?=?0.002). CONCLUSIONS:IMPT following IBR spared underlying organs and had low rates of acute toxicity. Reconstruction complications are more common in irradiated breasts, and reconstructive outcomes appear comparable with photon literature. Hypofractionation was associated with higher reconstruction failure rates. Further investigation of optimal dose-fractionation after IBR is needed.

Project description:OBJECTIVES:To characterize the psychosocial profiles of adult women diagnosed with Turner syndrome before (early diagnosis) and at or after (late diagnosis) 13 years of age. STUDY DESIGN:Women with Turner syndrome ages 22 and older at evaluation (n?=?110) participated in a cross-sectional study at the National Institutes of Health. Researchers performed nonparametric and logistic regression analyses to assess early and late diagnosis cohorts on measures of depression, substance use, and perceptions of competence and identity. RESULTS:Of study participants, 47% received a Turner syndrome diagnosis at or after age 13 years. Median age at diagnosis was 12.0 years (range, 0-43). Covariate-adjusted models revealed that women with late diagnoses had an increased likelihood of developing mild to severe depressive symptoms (OR,? 7.36) and a decreased likelihood of being perceived as competent (OR,?0.26). Women with a late diagnosis also exhibited more frequent substance use compared with women with early diagnoses. CONCLUSIONS:These data suggest that Turner syndrome diagnoses received at or after age 13 years may contribute to adverse outcomes related to depression, substance use, and perceptions of competence. Delayed Turner syndrome diagnoses may place women and girls at risk for negative psychosocial development extending into adulthood. These findings indicate it is important for pediatricians to evaluate psychosocial domains in girls with Turner syndrome regularly, particularly among those diagnosed at age 13 years or older.

Project description:Objective This study aimed to explore the influencing factors of adverse outcomes in the offspring of women with epilepsy (WWE) and to analyze the changes brought about by the epilepsy knowledge popularization campaign in China (EKPCIC). Methods This nested case-control study focused on WWE and their offspring from a female epilepsy cohort in mainland China. From January 2009 to August 2022, WWE was prospectively enrolled in 32 study centers. This study aimed to observe the health outcomes of their offspring within 1 year of age. The main outcome measure assessed the health status of the offspring within their first year of age. We aimed to analyze the effects of seizures, anti-seizure medicines (ASMs), and a lack of folic acid supplementation on adverse outcomes in the offspring of WWE and to explore the changes in perinatal management and adverse outcomes of the offspring after dissemination of the EKPCIC in 2015. Additionally, subgroup analyses were conducted to compare seizure control during pregnancy between the valproate and non-valproate groups. Results In total, 781 pregnancies in 695 WWE were included, of which 186 (23.69%) had adverse outcomes. The National Hospital Epilepsy Severity Scale score, number of seizures, status epilepticus, ASM type, and valproate and folic acid doses were associated with a high risk of adverse outcomes. After the EKPCIC, the use of ASMs (P = 0.013) and folic acid (P < 0.001), the seizure-free rate during pregnancy (P = 0.013), and the breastfeeding rate (P < 0.001) increased, whereas the incidence of complications during pregnancy decreased (P = 0.013). However, there was no significant difference in the incidence of adverse outcomes between the analyzed offspring pre-/post-EKPCIC. Additionally, there was no association between the frequency of seizures at different time points during pregnancy and the use of valproate (F = 1.514, P = 0.221). Conclusion Possible factors influencing adverse outcomes in the offspring of WWE include seizures, type and number of ASM usage, and a lack of folic acid supplementation. Although the management of WWE during pregnancy is now more standardized, further efforts are needed to reduce adverse outcomes in offspring.

Project description:ObjectiveTo investigate whether men and women who were looked-after (in public care) or adopted as children are at increased risk of adverse psychological and social outcomes in adulthood.Design, settingProspective observational study using the Avon Longitudinal Study of Parents and Children, which recruited pregnant women and their male partners in and around Bristol, UK in the early 1990s.Participants8775 women and 3654 men who completed questionnaires at recruitment (mean age: women 29; men 32) and 5?years later.ExposureChildhood public care status: looked-after; adopted; not looked-after or adopted (reference group).OutcomesSubstance use (alcohol, cannabis, tobacco) prepregnancy and 5?years later; if ever had addiction; anxiety and depression during pregnancy and 5?years later; if ever had mental health problem; social support during pregnancy; criminal conviction.ResultsFor women, 2.7% were adopted and 1.8% had been looked-after; for men, 2.4% and 1.4%, respectively. The looked-after group reported the poorest outcomes overall, but this was not a universal pattern, and there were gender differences. Smoking rates were high for both the looked-after (men 47%, women 58%) and adopted (men 44%, women 40%) groups relative to the reference group (both 28%). The looked-after group were at increased risk of a high depression score (men: 26% vs 11%, OR 2.9 (95% CI 1.5 to 5.6); women: 24% vs 9%, 3.4 (2.2 to 5.0)). A high anxiety score was reported by 10% of the reference women, compared with 26% of those looked-after (3.0 (2.0 to 4.5)) and 17% of those adopted (1.8 (1.2 to 2.6)). Looked-after men and women reported the lowest social support, while criminal convictions and addiction were highest for looked-after men. Adjustment for adult socioeconomic position generally attenuated associations for the looked-after group.ConclusionsThe needs of those who experience public care as children persist into adulthood. Health and social care providers should recognise this.

Project description:PurposeLittle is known about the illness experience from the perspective of individuals with dementia (IWDs), as most quantitative research has focused on IWDs' psychosocial issues from proxy reports. The primary aim of this study was to better understand the impact of the illness experience on well-being from the perspective of the IWD through the framework of the Stress Process Model for Individuals with Dementia (SPM for IWDs).Design and methodsGuided by the SPM for IWDs, self-report data were collected from IWDs (N = 131) about their illness experience, including primary objective and subjective stressors, secondary role and intrapsychic strains, and well-being outcomes. Using multiple linear regression, primary stressors, secondary strains, and background and context characteristics were entered into 3 prediction models for each outcome: anxiety, depression, and quality of life (QoL).ResultsThree distinct prediction patterns emerged for each of the outcome measures. Embarrassment about memory loss was the unique predictor of anxiety, whereas physical health strain and role captivity uniquely predicted depression. Unique predictors for QoL included lower perceived instrumental activities of daily living (IADL) difficulty and higher self-efficacy.ImplicationsThis study provided valuable insight into the illness experience from the perspective of the IWD and identified key areas amenable to interventions, such as managing embarrassment about memory problems as well as improving self-efficacy and inner strength. Moreover, this study provided additional support for the inclusion of IWDs in the research process and highlighted the need for further research regarding clinical application of findings, testing of hypotheses, and analyzing efficacy of interventions.

Project description:Reducing delay to accessing care is necessary to reduce the Tuberculosis (TB) burden in high incidence countries such as India. This study aimed to identify factors associated with delays in seeking care for TB in Southern India.We analyzed data from newly diagnosed, smear-positive, culture-confirmed, pulmonary TB patients in the Regional Prospective Observational Research for TB (RePORT) cohort in Puducherry and Tamil Nadu, India. Data were collected on demographic characteristics, symptom duration, and TB knowledge, among other factors. Delay was defined as cough ≥4 weeks before treatment initiation. Risky alcohol use was defined by the AUDIT-C score which incorporates information about regular alcohol use and binge drinking. TB knowledge was assessed by knowing transmission mode or potential curability.Of 501 TB patients, 369 (73.7%) subjects delayed seeking care. In multivariable analysis, risky alcohol use was significantly associated with delay (aOR 2.20, 95% CI: 1.31, 3.68). Delay was less likely in lower versus higher income groups (<3000 versus >10,000 rupees/month, aOR 0.31, 95% CI: 0.12, 0.78). TB knowledge was not significantly associated with delay.Local TB programs should consider that risky alcohol users may delay seeking care for TB. Further studies will be needed to determine why patients with higher income delay in seeking care.
