Abstract
BACKGROUND Virtual simulation-based education for healthcare professionals has emerged as a strategy for dealing with infectious disease disasters, particularly when training at clinical sites is restricted due to the risk of infection and a lack of personal protective equipment. This research evaluated a virtual simulation-based education program intended to increase nurses' perceived competence in providing psychological support to patients affected by infectious disease disasters. METHODS The efficacy of the program was evaluated via a randomized controlled trial. We recruited 104 nurses for participation in the study and allocated them randomly and evenly to an experimental group and a control group. The experimental group was given a web address through which they could access the program, whereas the control group was provided with a web address that directed them to text-based education materials. Data were then collected through an online survey of competence in addressing disaster mental health, after which the data were analyzed using the Statistical Package for the Social Sciences(version 23.0). RESULTS The analysis showed that the experimental group's disaster mental health competence (F = 5.149, p =.026), problem solving process (t = 3.024, p =.003), self-leadership (t = 2.063, p =.042), learning self-efficacy (t = 3.450, p =.001), and transfer motivation (t = 2.095, p =.039) significantly statistically differed from those of the control group. CONCLUSIONS A virtual nursing simulation-based education program for psychological support can overcome limitations of time and space. The program would also be an effective learning resource during infectious disease outbreaks. CLINICAL TRIAL REGISTRATION This Korean clinical trial was retrospectively registered (21/11/2023) in the Clinical Research Information Service ( https://cris.nih.go.kr ) with trial registration number KCT0008965.

Abstract
PURPOSE/OBJECTIVES We aim to explore Current Procedural Terminology (CPT) codes for caregiving training services and their potential impacts on caregivers of people living with dementia. DESCRIPTION OF THE PROJECT/PROGRAM In response to the growing need for support for caregivers of people living with physical and mental health issues, CPT codes for caregiving training services will be activated for the calendar year 2024. These codes cover (1) family group behavior management and modification training services and (2) caregiver training for techniques to help patients maintain their quality of life. Caregivers will access such training support through the CPT codes provided by treating practitioners. The duration of training will vary by code. OUTCOME Implementing CPT codes for caregiver training services highlights the vital role of caregivers in patient care. This support may improve their skills and communication with healthcare providers. However, timing and accessibility in care delivery need clarification, especially for caregivers of people living with dementia. Regular skill assessment and culturally competent care are essential. Before providing the service, provider training may also promote person-centered care, benefiting patients and their caregivers. CONCLUSION Activating CPT codes for caregiving training services may enhance caregivers' support and skills, including dementia care.

Abstract
PURPOSE/OBJECTIVE(S) Despite evidence of preclinical synergy between radiotherapy (RT) and immune checkpoint blockade (ICB), randomized trials of RT/ICB have demonstrated limited benefit in solid tumors. We performed single-cell RNA sequencing (scRNA-seq) and CITE-seq (cellular indexing of transcriptomes and epitopes) to address the discordance between preclinical and clinical data. We hypothesized that multiple orthogonal inhibitory immune pathways restrain the local and systemic efficacy of RT beyond T-cell oriented immune checkpoints. MATERIALS/METHODS We used the EO771 syngeneic murine model of breast cancer to characterize the immune tumor microenvironment following RT with or without ICB. RT (16 Gy x 1) was delivered using the X-RAD SmART platform with CT image guidance. Neutralizing antibodies (anti-PD-1/Ly6G/Gr-1/CD47) were delivered by intraperitoneal injections. scRNA-seq analysis were performed by Seurat and BBrowser (BioTuring). RESULTS We found that adaptive ICB (anti-PD-1) reprogrammed the immune response to RT by promoting an M1-like interferon-primed state (ISG15, CXCL10) in tumor associated macrophages (TAMs) and by increasing the late recruitment of intratumoral neutrophils. Given that neutrophils may drive resistance to RT in other models, we evaluated the effect of intratumoral neutrophil depletion using anti-Ly6G or anti-Gr-1 on the antitumor efficacy of RT/ICB. Both neutrophil depletion strategies led to enhanced tumor control and improved survival in advanced EO771 tumors compared to RT/ICB alone (P<0.001). In parallel to this approach, we found that TAMs upregulated several innate immune checkpoints including SIRPα in response to RT. Disruption of the SIRPα-CD47 interaction by anti-CD47 antibodies similarly enhanced the antitumor efficacy of RT/ICB by improving tumor control and survival (P<0.001). Using scRNA-seq and unbiased clustering, we found that anti-CD47 eliminated an entire cluster of chronically inflamed TAMs, characterized by pro-inflammatory markers (IL1A, NOS2) and chemokines (CCL3, CXCL1/2/3). Anti-CD47 also reduced intratumoral neutrophils by eliminating a cluster of pathologically activated neutrophils, termed myeloid-derived suppressor cells (PMN-MDSCs) that expressed several markers of ferroptosis (TFRC, PTGS2, SLC3A2). Consistent with the potent immunosuppressive capacity of PMN-MDSCs, we found that anti-CD47 increased tumor-infiltrating lymphocytes including central memory TCF7+ T cells and CD19+ B cells. Lastly, by inference and analysis of cell-cell communication (CellChat), we found that anti-CD47 strengthened the interactions between TAMs and CD8+ T cells compared to RT/ICB alone. CONCLUSION Our data collectively indicate that resistance to RT/ICB in the EO771 model Is driven by innate immune cells including neutrophils and chronically inflamed TAMs. Targeted disruption of the CD47-SIRPα axis is a promising approach to overcoming immune resistance by reprogramming TAMs and eliminating PMN-MDSCs.

Abstract
Posttraumatic stress disorder (PTSD) encompasses various psychological symptoms and a high early dropout rate due to treatment unresponsiveness. In recent years, neurofeedback has been implemented to control PTSD's psychological symptoms through physiological brain regulation. However, a comprehensive analysis concerning its efficacy is lacking. Therefore, we conducted a systematic review and meta-analysis to determine neurofeedback's effect on reducing PTSD symptoms. We analyzed randomized and non-randomized controlled trials (RCTs) from 1990 to July 2020, evaluating neurofeedback treatments for those diagnosed with PTSD and their symptoms. In addition, we calculated the standardized mean difference (SMD)using random-effects models to estimate effect sizes. We assessed ten articles comprising 276 participants, with a - 0.74 SMD (95% confidence interval = - 0.9230, - 0.5567), 42% I2, moderate effect size, and - 1.40 to -0.08 prediction intervals (PI). Neurofeedback was more effective for complex trauma PTSD patients than single trauma. Increasing and lengthening sessions are more effective than fewer, condensed ones. Neurofeedback positively affected arousal, anxiety, depression, and intrusive, numbing, and suicidal thoughts. Therefore, neurofeedback is a promising and effective treatment for complex PTSD.

Abstract
Family caregivers for persons with dementia often times experience stress and burden while caregiving. The COVID-19 pandemic has worsened this situation with increased physical and social isolation, further resulting in health risks in this population. Technology-based interventions have become more commonplace in today’s world to address ongoing caregiver needs although gaps in technological literacy and usage still exist among many users. This case study aims to report on the implementation of an ongoing Smarthealth technology intervention for two older adult family caregivers of persons with dementia and to explore their experiences with this system. Data were collected through acoustic monitoring, survey administration, and semi-structured interviews. Intervention effects on changes in emotional states will be discussed. Study findings showed the intervention improved self-awareness of emotional care and reactions to care recipients. Findings in this study highlight the importance and challenges of real-time technology-based intervention implementation in older adult caregiving populations.

Abstract
Background: Breast cancer survivors who report chronic pain in the affected ipsilateral upper limb or body are nearly twice as likely to develop lymphedema. Little is known about lymphatic pain, defined as co-occurring pain and swelling in the affected ipsilateral upper limb or body. The study aimed to examine the predictors and effects of lymphatic pain on breast cancer survivors' activities of daily living (ADLs). Materials and Methods: A sample of 568 patients was recruited in a metropolitan cancer center in the United States. Demographic and clinical data were collected. Body mass index (BMI) and limb volume were measured using infra-red perometer. Lymphatic pain and ADLs were measured by the Lymphedema and Breast Cancer Symptom Experience Index. Parametric and nonparametric tests and generalized linear models were used to analyze data. Results: Lymphatic pain affected 33% of survivors. Significant predictors of lymphatic pain included younger age, higher BMI, financial hardship, and a diagnosis of lymphedema. Patients with a diagnosis of lymphedema had 9.68 odds (confidence interval [CI]: 5.78-16.63; p < 0.001) and those with financial hardship had 4.64 odds (CI: 1.99-11.32; p = 0.001) of experiencing lymphatic pain. Patients with lymphatic pain had more impairments in ADLs (p < 0.001) compared to patients with only pain, only swelling, and no symptoms. Significantly more patients with lymphatic pain had a limb volume difference of >5% and >10% compared to patients with only pain and no symptom. Conclusion: This study is the first to report that in a large sample of patients, 33.1% experienced lymphatic pain and that lymphatic pain was associated with significant impairments in ADLs. Findings suggest that lymphatic pain may be due to abnormal accumulation of lymph fluid. Research is needed to ascertain the physiological mechanisms that underlie lymphatic pain and determine whether strategies to prevent and treat lymphedema can decrease lymphatic pain.

Abstract
Moiré superlattices formed by stacking two-dimensional crystals have reinvigorated the pursuit for emergent functionalities of engineered superlattices. Unique optical characteristics can be realized from the interplay between the electronic excitations and the atomic rearrangements owing to their intrinsic softness. Although large-scale reconstructions have been identified at small twist angles, they have been treated as being rigid at large twist angles. Here, we report that moiré superlattices made from single layers of MoS2 and WSe2 exhibit a pair of torsional strains with opposite chirality irrespective of the twist angle. The whirlpool-shaped periodic lattice distortions introduce fuzziness in the Raman spectra and universal redshifts to the intralayer excitons for all twist angles. We show that both of these modulations become weaker as the twist angle increases but do not disappear, whereas they are turned off when the constituent layers are not tightly coupled, thus establishing an essential structure-property relationship for moiré superlattices.

Abstract
Mentorship is important for doctoral education and development. Students in Doctor of Philosophy (PhD) in Nursing programs traditionally receive formal mentorship from more experienced faculty mentors, creating a top-down, mentor-mentee relationship. Peer mentorship, characterized by a mentor-mentee relationship between peers in similar career stages, provides unique opportunities for career development and socialization. The emergence of the COVID-19 pandemic limited in-person interactions and introduced new, complex challenges to peer mentorship. The authors, current and recently graduated PhD in Nursing students, were forced to create new ways of connecting with peers and sought to explore how other PhD in Nursing students experienced and maintained peer mentorship in their respective programs during the pandemic. In this article, the authors share their personal experiences with peer mentorship during the pandemic, their process of creating a formal peer mentor model, and findings from a national, cross-sectional survey on COVID-related, peer mentorship experiences among PhD in Nursing students from other academic institutions. Most respondents were able to maintain peer mentorship throughout the pandemic, however, less than half reported receiving faculty support to do so. Recommendations for PhD in Nursing program administrators are provided, based on the experiences of the authors and survey results from PhD in Nursing students across the United States.

Abstract
BACKGROUND Fatigue and lymphatic pain are the most common and debilitating long-term adverse effects of breast cancer treatment. Fatigue and pain independently have negative effects on quality of life, physical functions, and cancer recurrence-free survival. The interactions between fatigue and pain may aggravate their negative effects. OBJECTIVES Examine the effects of co-occurring fatigue and lymphatic pain on activities of daily living (ADLs), emotional distress, and overall health of breast cancer patients. METHODS A cross-sectional and observational design was used to enroll 354 breast cancer patients. Valid and reliable instruments were used to assess fatigue, lymphatic pain, ADLs, emotional distress, and overall health. Descriptive statistics and multivariable regression models were used for data analysis. RESULTS After controlling for demographic and clinical factors, patients with co-occurring fatigue and lymphatic pain had higher odds of having impaired ADLs (OR = 24.43, CI = [5.44-109.67], P < .001) and emotional distress (OR = 26.52, CI = [9.64-72.90], P < .001) compared to patients with only fatigue and only lymphatic pain. Patients with co-occurring fatigue and lymphatic pain had 179% increase in impaired ADL scores (B = 8.06, CI = [5.54-10.59]) and 211% increase in emotional distress scores (B = 9.17, CI = [5.52-12.83]) compared to those without co-occurring fatigue and lymphatic pain. Patients with co-occurring fatigue and lymphatic pain had a 34% decrease (B = -26.29, CI = [-31.90 to -20.69]) and patients with only fatigue had a 33% decrease in overall health scores (B = -25.74, 95% CI = [-34.14 to -17.33]), indicating poor overall health. CONCLUSIONS Fatigue and lymphatic pain affected 66.4% of breast cancer patients. Findings from this study suggest that co-occurring fatigue and lymphatic pain have negative effects on breast cancer patients' ADLs, emotional distress, and overall health. The synergistic interactions between fatigue and lymphatic pain incrementally aggravated their negative effects on ADLs and emotional distress. Findings of the study highlight the need to evaluate the underlying mechanisms for co-occurring fatigue and lymphatic pain and develop interventions that target both fatigue and lymphatic pain to improve breast cancer patients' the quality of life.

African Americans (AA) family caregivers provide the bulk of unpaid care to persons living with dementia (PLWD). This role leaves little time for the adoption of self-care behaviors—critical to the prevention and management of chronic diseases. In this systematic review, we appraise caregiver self-care interventions that include AA caregivers of PLWD. PubMed, CINAHL, PsycINFO, Cochrane, and Embase databases were searched. Terms included AA/Black, self-care, caregiving, lifestyle, intervention, psychological stress, and faith/community. We initially found 250 references and after application of exclusion criteria and removal of redundant references, 18 articles were analyzed. Most interventions focused on impacting levels of caregiver burden, depression, physical activity, anxiety, or wellbeing. Psychoeducation, physical activity, and spiritually-focused interventions were most effective in improving outcomes in caregivers. Future studies should examine the impact of interventions on the prevention and management of chronic disease in AA caregivers of PLWD.

Abstract
Caregiving stress from repetitive and heavy caregiving workloads can trigger poor emotional health, such as stress, anxiety, and depression, leading to higher caregiver mortality rates. Interest in technology-based interventions for this population has increased among researchers due to availability, acceptability, and flexibility compared to in-person services, especially now, during an unprecedented pandemic. Our study focuses on in-home SmartHealth technologies for caregivers of persons with Alzheimer’s Disease and related dementias, delivered using Ecological Momentary Assessment and a novel acoustic monitoring, mood recognition, and self-learning recommendation system. The system provides mindfulness-based stress management in response to interpersonal conflict in real-time. We will report challenges and solutions of creating and deploying a SmartHealth system for older adults in their home during the COVID-19 pandemic. Potential effects of this system on caregivers' emotional health are also examined. Findings suggest SmartHealth technologies may assist caregiving populations adapt and thrive in a new, more isolated normal.

Abstract
OBJECTIVES This study aimed to investigate the effect of depression on suicidal behavior among older adults and identify the mediating effect of life satisfaction on the relationship between depression and suicidal behavior. The moderated mediating effects of social support through life satisfaction were also verified in the relationship between depression and suicidal behavior among older adults. METHODS A total of 1375 people aged 65 years or older living in J city, South Korea, were recruited to complete a survey on depression, life satisfaction, suicidal behavior, and social support. Data were analyzed using SPSS24.0 and SPSS PROCESS Macro. RESULTS The results showed that the effect of depression on suicidal behavior was mediated by life satisfaction, and the effect of life satisfaction on suicidal behavior varied according to the level of social support. Moreover, depression negatively affected life satisfaction, increasing the risk of suicidal behavior, and social support decreased suicidal behavior. Finally, the mediating effect of depression leading to suicidal behavior through life satisfaction was moderated by social support. CONCLUSIONS These findings suggest that it is necessary not only to find interventions for older adults to increase their physical, mental, and socioeconomical satisfaction with life, but also to build social networks that increase social support for them.

Abstract
Lymphatic pain and swelling due to lymph fluid accumulation are the most common and debilitating long-term adverse effects of cancer treatment. This study aimed to quantify the effects of obesity on lymphatic pain, arm, and truncal swelling. Methods: A sample of 554 breast cancer patients were enrolled in the study. Body mass index (BMI), body fat percentage, and body fat mass were measured using a bioimpedance device. Obesity was defined as a BMI ≥ 30 kg/m2. The Breast Cancer and Lymphedema Symptom Experience Index was used to measure lymphatic pain, arm, and truncal swelling. Multivariable logistic regression models were used to estimate the odds ratio (OR) with 95% confidence interval (CI) to quantify the effects of obesity. Results: Controlling for clinical and demographic characteristics as well as body fat percentage, obesity had the greatest effects on lymphatic pain (OR 3.49, 95% CI 1.87-6.50; p < 0.001) and arm swelling (OR 3.98, 95% CI 1.82-4.43; p < 0.001). Conclusions: Obesity is a significant risk factor for lymphatic pain and arm swelling in breast cancer patients. Obesity, lymphatic pain, and swelling are inflammatory conditions. Future study should explore the inflammatory pathways and understand the molecular mechanisms to find a cure.

Abstract
AIM The aim of this study is to develop a Smarthealth system of monitoring, modelling, and interactive recommendation solutions (for caregivers) for in-home dementia patient care that focuses on caregiver-patient relationships. DESIGN This descriptive study employs a single-group, non-randomized trial to examine functionality, effectiveness, feasibility, and acceptability of the novel Smarthealth system. METHODS Thirty persons with Alzheimer's Disease or related dementia and their family caregivers (N = 30 dyads) will receive and install Smarthealth technology in their home. There will be a 1-month observation phase for collecting baseline mood states and a 2-month implementation phase when caregivers will receive stress management techniques for each detected, negative mood state. Caregivers will report technique implementation and usefulness, sent via Ecological Momentary Assessment system to the study-provided smartphone. Caregivers will provide daily, self-reported mood and health ratings. Instruments measuring caregiver assessment of disruptive behaviours and their effect on caregivers; caregiver depressive symptoms, anxiety and stress; caregiver strain; and family functioning will be completed at baseline and 3 months. The study received funding in 2018 and ethics board approval in 2019. DISCUSSION This study will develop and test novel in-home technology to improve family caregiving relationships. Results from this study will help develop and improve the Smarthealth recommendation system and determine its usefulness, feasibility, and acceptability for persons with dementia and their family caregiver. IMPACT The Smarthealth technology discussed will provide in-home stress reduction resources at a time when older adults may be experiencing increasingly high rates of isolation and anxiety and caregiver dyads may be experiencing high levels of relationship strain. TRIAL REGISTRATION This study was registered with Clinical Trials.gov (Identifier NCT04536701).

Abstract
BACKGROUND The-Optimal-Lymph-Flow (TOLF) intervention aims to promote lymph flow through therapeutic lymphatic exercises to relieve lymphatic pain, swelling, lymphedema symptoms, and to decrease lymph fluid levels among breast cancer survivors. To enhance the efficacy of the TOLF intervention, an innovative, intelligent, Kinect-enhanced lymphatic exercise intervention (Kinect-TOLF) was developed to teach patients to perform the lymphatic exercises correctly. OBJECTIVES This feasibility trial aimed to determine the feasibility, usability, and effects of the Kinect-TOLF on lymphatic pain, swelling, lymphedema symptoms, and lymph fluid levels. METHODS A single-arm feasibility trial with a pre- and post-test design was employed to recruit 30 breast cancer survivors with persistent lymphatic pain or swelling. Patients received a single training session to learn how to perform the lymphatic exercises using the Kinect-TOLF program. Descriptive statistics, Wilcoxon signed-rank tests, t-test, Spearman's rank correlation coefficients, linear regressions, and Cohen's d were performed for data analysis. Qualitative data were assessed for common themes. RESULTS The Kinect-TOLF was effective in training patients to perform the lymphatic exercises correctly with high user satisfaction. Significant reductions were found in scores of lymphatic pain (MedΔ = -1.00, CI = [-1.5, -0.1], P = .004), arm/hand swelling (MedΔ = -1.00, CI = [-1.5, -0.5], P = .004), total swelling (MedΔ = -1.5, CI = [-2.0, -1.0], P = .003), number of lymphedema symptoms (MΔ = -3.8, CI = [-5.5, -2.1], P < .001), and lymphedema symptom severity (MΔ = -5.3, CI = [-9.5, -1.1], P = .016). A significant reduction in lymph fluid levels was found in mean L-Dex scores (MΔ = -2.68, CI = [-4.67, -0.69], P = .010). Greater decrease in mean L-Dex scores were found in patients with abnormal lymph fluid levels (L-Dex ≥ 7.1) (MΔ = -5.19, CI = [-1.75, -8.63], P = .008). Patients' qualitative feedback supported the results of the study. CONCLUSIONS The Kinect-TOLF is safe, feasible, and effective in reducing lymphatic pain, swelling, lymphedema symptoms, and in decreasing lymph fluid levels. Future research should focus on a randomized clinical trial to confirm the unique or synergistic efficacy of the Kinect-TOLF in comparison with current lymphedema treatment and other forms of exercises or movement therapy. This study was registered in ClinicalTrials.gov with US ClinicalTrials.gov Identifier: NCT03999177.

Abstract
Background: Breast cancer-related lymphedema (BCRL) limits the movements of patients' limbs, which leads to a diminished ability to achieve essential activities of daily living (ADLs). The purpose of this study was to examine the associations between limb volume changes from the baseline before breast cancer surgery and self-reported difficulty in performing ADLs at 12 months following cancer surgery. We hypothesized that a positive association existed between limb volume changes from the baseline and self-reported difficulty in performing ADLs at 12 months following breast cancer surgery. Methods and Results: The data of the present study were part of a larger study with 140 breast cancer patients recruited before breast cancer surgery and followed up during their first year of treatment. Patients with more than 10% limb volume increase reported more frequent distress in performing 13 ADL items, compared with patients whose limb volume increased by 5%–10%. Regression analysis showed a significant increase in the odds ratio of reporting difficulty in ADLs compared with the group with less than 5% limb volume increase. Conclusion: Overall, patients with a greater limb volume increase underwent more difficulty performing ADLs. Patients reported more difficulty in performing ADLs even with 5%–10% limb volume increase. Currently, there is no standardized guideline to diagnose BCRL, although previous evidence suggests a limb volume increase greater than 10% as a criterion for BCRL. The findings from the present study suggest a more precise and clinically meaningful criteria for diagnosing BCRL to accommodate those with 5%–10% increase in limb volume.

Abstract
This study was conducted to explore nursing students' emotional experiences during simulations, and to develop a debriefing model for psychological safety in nursing simulations by qualitatively analyzing data. Data were collected through face-to-face in-depth interviews with 23 undergraduate nursing students in South Korea. Via content analysis, nine categories were derived: fear of evaluation, burden of being observed, unfamiliarity with new ways of learning, sensitivity to interpersonal relationships, physical and emotional exhaustion, utilization of supportive relationships, decline in learning satisfaction, positive acceptance of stress, and attempts to relieve stress. On the basis of these insights, we developed the Share-Explore-Notice-Support-Extend (SENSE) debriefing model, which includes stress management and emotional support, as a strategy for effective simulation practices to reduce the negative experiences of stress in nursing students in simulation-based learning.

Abstract
The novel electronic state of the canted antiferromagnetic (AFM) insulator strontium iridate (Sr2 IrO4 ) is well described by the spin-orbit-entangled isospin Jeff = 1/2, but the role of isospin in transport phenomena remains poorly understood. In this study, antiferromagnet-based spintronic functionality is demonstrated by combining the unique characteristics of the isospin state in Sr2 IrO4 . Based on magnetic and transport measurements, a large and highly anisotropic magnetoresistance (AMR) is obtained by manipulating the AFM isospin domains. First-principles calculations suggest that electrons whose isospin directions are strongly coupled to the in-plane net magnetic moment encounter an isospin mismatch when moving across the AFM domain boundaries, which generates a high resistance state. By rotating a magnetic field that aligns in-plane net moments and removes domain boundaries, the macroscopically ordered isospins govern dynamic transport through the system, which leads to the extremely angle-sensitive AMR. As this work establishes a link between isospins and magnetotransport in strongly spin-orbit-coupled AFM Sr2 IrO4 , the peculiar AMR effect provides a beneficial foundation for fundamental and applied research on AFM spintronics.

Abstract
Abstract
Background: The management of benign intraductal papillomas on core biopsy is controversial. The aim of this study was to determine factors that predict under-evaluation of atypical lesion or malignancy in patients diagnosed with benign papilloma at ultrasound-guided core needle biopsy (CNB), and to develop a prediction algorithm for scoring the possibility of a diagnosis upgrade to atypical lesion or malignancy based on clinical, radiological and pathological factors.
Methods: The study enrolled patients diagnosed with benign papilloma at ultrasound-guided CNB who subsequently underwent surgical excision of the lesion. Multivariate analysis was used to identify relevant clinical, radiological and pathological factors that may predict malignancy.
Results: A total of 520 CNBs led to a diagnosis of benign papilloma (including benign and atypical papillary lesion), of which 452 CNBs were benign papilloma without atypia. Of the 250 lesions in 234 women were underwent subsequent surgical excision, 44 (17.6%) were diagnosed with atypia or malignancy. Multivariate analysis revealed that bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion were independent predictors of atypical lesion or malignancy. A scoring system was developed based on logistic regression models and beta coefficients for each variable. The area under the ROC curve was 0.830 (95% CI: 0.665-0.996), and the negative predictive value was 100% for a score ≤4.
Conclusions: A scoring system to predict malignancy in patients diagnosed with benign papilloma at CNB was developed based on five factors: bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion. This system was able to identify a subset of patients with lesions likely to be benign, indicating that imaging follow-up rather than surgical excision may be appropriate.

Abstract
The prognostic role of aberrant serum miRNA expression for predicting response to sorafenib treatment in advanced hepatocellular carcinoma (HCC) patients has not been well characterized. We aimed to identify specific serum miRNAs that are associated with positive radiologic responses or improved survival in sorafenib-treated HCC patients. miR-18a, miR-21, miR-139-5p, miR-221, miR-224, and miR-10b-3p, were selected for analysis. Serum samples from 24 patients with advanced stage HCC and 25 patients with liver cirrhosis (LC) were analyzed. All of the miRNAs except miR-21 were found to be upregulated in serum samples from HCC patients. None of the miRNAs assayed differed significantly in terms of expression between the responder and non-responder groups among HCC patients. However, miR-10b-3p levels were significantly higher in the subgroup of HCC patients with worse overall survival (fold change = 5.8, P = 0.008). Serum miRNA-10b-3p was upregulated in the presence of macrovascular invasion (MVI), and those with higher serum miRNA-10b-3p had significantly shorter survival during treatment (P = 0.042). Although no single serum miRNA was predictive of response to sorafenib treatment, analysis of serum miR-10b-3p levels may be valuable for diagnosis of HCC and prediction of survival of sorafenib-treated patients.

Abstract
The immunosuppressive effects of Sophorae radix (SR) make this plant an attractive agent for the treatment of autoimmune diseases. The effect of SR on systemic lupus erythematosus (SLE) in the New Zealand Black/White F1 (NZB/w F1) mouse model system was investigated. Three-month-old NZB/w F1 mice were separated into two groups: one treated with SR (1% SR solution by oral administration, daily for 15 weeks) and one with water as a control. Experimental parameters include proteinuria, anti-dsDNA antibody titers, T-cell response and renal histopathological analysis. Results in the SR-treated group showed a significant reduction in proteinuria and anti-dsDNA antibodies either in serum or in glomerular capillaries, along with significant recovery from renal glomerular damage. The lymphocyte population was significantly increased in the SR-treated mice compared with the control group. In the T helper (Th)1/Th2 cytokine secretion profile, interferon-γ in splenocyte culture was significantly reduced in the SR-treated mice, while interleukin-4 secretion was not altered. These results strongly suggest SR therapy corrects the deviated Th1/Th2 balance, thereby alleviating SLE-like symptoms in the NZB/w F1 mice. Therefore, SR may be useful in the clinical treatment of SLE. Lupus (2007) 16, 335—341.

Abstract
To evaluate the association between smoking and physician-diagnosed stroke and myocardial infarction, this study used Community Health Survey data from 2009 on 92,082 males over the age of 30 years. Using multiple logistic regression, association index between smoking and physician-diagnosed stroke and myocardial infarction was calculated after adjusting the effects of age, hypertension, and diabetes. The odds ratios (95% confidence interval) of the physician-diagnosed stroke and myocardial infarction in the smoking group were 1.12 (1.02–1.24) and 1.21 (1.06–1.38) compared to the non-smoking group. The values of the physician-diagnosed stroke and myocardial infarction were 0.84 (0.74–0.94) and 0.96 (0.82–1.12) in the current-smoking subgroup, 1.38 (1.24–1.53) and 1.45 (1.26–1.67) in the ex-smoking subgroup, 1.39 (1.18–1.63) and 1.85 (1.53–2.24) in the 10- to 19-year smokers groups, 1.39 (1.22–1.58) and 1.36 (1.15–1.60) in the 30- to 40-year smokers groups, and 0.53 (0.44–0.63) and 0.47 (0.36–0.63) in those who had smoked for over 50 years. These results showed smoking was a risk factor for stroke and myocardial infarction in Korean males. This objective evidence should guide policy-making and public health interventions in the fields of smoking prevention and prohibition.

Abstract
Nanoparticulation of insoluble drugs improves dissolution rate, resulting in increased bioavailability that leads to increased stability, better efficacy, and reduced toxicity of drugs. Docetaxel (DTX), under the trade name Taxotere™, is one of the representative anticancer chemotherapeutic agents of this era. However, this highly lipophilic and insoluble drug has many adverse effects. Our novel and widely applicable nanoparticulation using fat and supercritical fluid (NUFS™) technology enabled successful nanoscale particulation of DTX (Nufs-DTX). Nufs-DTX showed enhanced dissolution rate and increased aqueous stability in water. After confirming the preserved mechanism of action of DTX, which targets microtubules, we showed that Nufs-DTX exhibited similar effects in proliferation and clonogenic assays using A549 cells. Interestingly, we observed that Nufs-DTX had a greater in vivo tumor growth delay effect on an A549 xenograft model than Taxotere™, which was in agreement with the improved drug accumulation in tumors according to the biodistribution result, and was caused by the enhanced permeability and retention (EPR) effect. Although both Nufs-DTX and Taxotere™ showed negative results for our administration dose in the hematologic toxicity test, Nufs-DTX showed much less toxicity than Taxotere™ in edema, paralysis, and paw-withdrawal latency on a hot plate analysis that are regarded as indicators of fluid retention, peripheral neuropathy, and thermal threshold, respectively, for toxicological tests. In summary, compared with Taxotere™, Nufs-DTX, which was generated by our new platform technology using lipid, supercritical fluid, and carbon dioxide (CO2), maintained its biochemical properties as a cytotoxic agent and had better tumor targeting ability, better in vivo therapeutic effect, and less toxicity, thereby overcoming the current hurdles of traditional drugs.

Abstract
Background The majority of research on obesity has focused primarily on clinical features (eating behavior, adiposity measures), or peripheral appetite-regulatory peptides (leptin, ghrelin). However, recent functional neuroimaging studies have demonstrated that some reward circuitry regions which are associated with appetite-regulatory hormones are also involved in the development and maintenance of obesity. Prader-Willi syndrome (PWS), characterized by hyperphagia and hyperghrelinemia reflecting multi-system dysfunction in inhibitory and satiety mechanisms, serves as an extreme model of genetic obesity. Simple (non-PWS) obesity (OB) represents an obesity control state. Objective This study investigated subcortical food motivation circuitry and prefrontal inhibitory circuitry functioning in response to food stimuli before and after eating in individuals with PWS compared with OB. We hypothesized that groups would differ in limbic regions (i.e., hypothalamus, amygdala) and prefrontal regions associated with cognitive control [i.e., dorsolateral prefrontal cortex (DLPFC), orbitofrontal cortex (OFC)] after eating. Design and Participants Fourteen individuals with PWS, 14 BMI- and age-matched individuals with OB, and 15 age-matched healthy-weight controls (HWC) viewed food and non-food images while undergoing functional MRI before (pre-meal) and after (post-meal) eating. Using SPM8, group contrasts were tested for hypothesized regions: hypothalamus, nucleus accumbens (NAc), amygdala, hippocampus, OFC, medial PFC, and DLPFC. Results Compared with OB and HWC, PWS demonstrated higher activity in reward/limbic regions (NAc, amygdala) and lower activity in hypothalamus and hippocampus, in response to food (vs. non-food) images pre-meal. Post-meal, PWS exhibited higher subcortical activation (hypothalamus, amygdala, hippocampus) compared to OB and HWC. OB showed significantly higher activity versus PWS and HWC in cortical regions (DLPFC, OFC) associated with inhibitory control. Conclusion In PWS compared with obesity per se, results suggest hyperactivations in subcortical reward circuitry and hypoactivations in cortical inhibitory regions after eating, which provides evidence of neural substrates associated with variable abnormal food motivation phenotypes in PWS and simple obesity.

Abstract
281 Background: There is controversy about the benefit of chemotherapy-induced amenorrhea (CIA) in breast cancer. We investigated significance of CIA after neoadjuvant chemotherapy for predicting response to neoadjuvant chemotherapy in breast cancer patients. Methods: We reviewed the records of 198 premenopausal patients with breast cancer treated with neoadjuvant chemotherapy between January 2005 and December 2010. Chemotherapy-induced amenorrhea (CIA) was defined as serum FSH level ≥40 IU/L after completion of all scheduled neoadjuvant chemotherapy and prior to definitive surgery. Results: Among 198 breast cancer patients, 132 pts (66.7%) developed CIA after neoadjuvant chemotherapy. 156 pts (78%) underwent DA chemotherapy. The age of CIA patients was older than non-CIA patients (41.55±5.55 vs. 38.27± 6.86 years, p=0.001). The incidence of CIA after neoadjuvant chemotherapy was significantly higher in responder group (responder vs. nonresponder: 87 pts (74.4%) vs. 45 pts (55.6%); p=0.006). Additionally, FSH level after all scheduled neoadjuvant chemotherapy was significantly higher in responder group (FSH 56.41±32.41 mIU/ml vs. 45.76±30.31 mIU/ml; p=0.021). In univariate analysis, CIA (p=0.006) and total number of chemotherapy cycle regardless of chemotherapy regimen (p=0.04) were significantly predictive of tumor response. CIA was only significant predictive factor for tumor response after neoadjuvant chemotherapy on multivariate analysis (p=0.012). Conclusions: CIA is independent predictive markers of response to neoadjuvant chemotherapy in locally advanced breast cancer.

Abstract
1,2,3,4,6-penta-O-galloyl-beta-D-glucose (PGG), a polyphenolic compound isolated from Rhus chinensis Mill. PGG has been known to have anti-tumor, anti-angiogenic and anti-diabetic activities. The present study revealed another underlying molecular target of PGG in MDA-MB-231 breast cancer cells by using Illumina Human Ref-8 expression BeadChip assay. Through the Beadstudio v3 micro assay program to compare the identified genes expressed in PGG-treated MDA-MB-231 cells with untreated control, we found several unique genes that are closely associated with pyruvate metabolism, glycolysis/gluconeogenesis and tyrosine metabolism, including PC, ACSS2, ACACA, ACYP2, ALDH3B1, FBP1, PRMT2 and COMT. Consistent with microarray data, real-time RT-PCR confirmed the significant down-regulation of these genes at mRNA level in PGG-treated MDA-MB-231 cells. Our findings suggest the potential of PGG as anticancer agent for breast cancer cells by targeting cancer metabolism genes.

Abstract
We report a case of a 54-year-old man with T4N0M0 non-small cell lung cancer directly invading the thoracic wall and aortic arch. He underwent neoadjuvant chemotherapy followed by en bloc resection of the tumor, lung, chest wall and aortic arch. Perfusion was maintained through femoral-femoral cardiopulmonary bypass, with permanent bypass to the arch vessels to avoid separate extracorporeal cerebral circulation. Total reconstructions of the chest wall and aortic arch were completed without the need for cardiac arrest. The final pathological diagnosis was squamous cell carcinoma, T4N0M0. The patient was discharged without major complications and has been free of disease for 20 months postoperatively.

Abstract
Clinical evidence indicates that electroacupuncture (EA) is effective for allergic disorder. Recent animal studies have shown that EA treatment reduces levels of IgE and Th2 cytokines in BALB/c mice immunized with 2,4-dinitrophenylated keyhole limpet protein (DNP-KLH). The hypothalamus, a brain center of the neural-immune system, is known to be activated by EA stimulation. This study was performed to identify and characterize the differentially expressed genes in the hypothalamus of DNP-KLH immunized mice that were stimulated with EA or only restrained. To this aim, we conducted a microarray analysis to evaluate the global gene expression profiles, using the hypothalamic RNA samples taken from three groups of mice: (i) normal control group (no treatments); (ii) IMH group (DNP-KLH immunization + restraint); and (iii) IMEA group (immunization + EA stimulation). The microarray analysis revealed that total 39 genes were altered in their expression levels by EA treatment. Ten genes, including T-cell receptor alpha variable region family 13 subfamily 1 (Tcra-V13.1), heat shock protein 1B (Hspa1b) and 2′–5′ oligoadenylate synthetase 1F (Oas1f), were up-regulated in the IMEA group when compared with the IMH group. In contrast, 29 genes, including decay accelerating factor 2 (Daf2), NAD(P)H dehydrogenase, quinone 1 (Nqo1) and programmed cell death 1 ligand 2 (Pdcd1lg2) were down-regulated in the IMEA group as compared with the IMH group. These results suggest that EA treatment can modulate immune response in DNP-KLH immunized mice by regulating expression levels of genes that are associated with innate immune, cellular defense and/or other kinds of immune system in the hypothalamus.

Abstract
To meet the stringent requirements of interconnect metallization for sub-32 nm technologies, an unprecedented level of flux and energy control of film forming species has become necessary to further advance ionized physical vapor deposition technology. Such technology development mandates improvements in methods to quantify the metal ion fraction, the gas∕metal ion ratio, and the associated ion energies in the total ion flux to the substrate. In this work, a novel method combining planar Langmuir probes, quartz crystal microbalance (QCM), and gridded energy analyzer (GEA) custom instrumentation is developed to estimate the plasma density and temperature as well as to measure the metal ion fraction and ion energy. The measurements were conducted in a Novellus Systems, Inc. Hollow Cathode Magnetron (HCM(TM)) physical vapor deposition source used for deposition of Cu seed layer for 65-130 nm technology nodes. The gridded energy analyzer was employed to measure ion flux and ion energy, which was compared to the collocated planar Langmuir probe data. The total ion-to-metal neutral ratio was determined by the QCM combined with GEA. The data collection technique and the corresponding analysis are discussed. The effect of concurrent resputtering during the deposition process on film thickness profile is also discussed.
