The effect of dietary interventions or patterns on the cardiometabolic health of individuals treated with androgen deprivation therapy for prostate cancer: A systematic review

Prostate cancer survivors treated with androgen deprivation therapy may be at increased risk of cardiovascular disease. Dietary recommendations for the prevention and/or management of cardiovascular disease for these individuals are lacking. This review synthesizes the evidence on the effect of dietary interventions on cardiometabolic biomarkers and cardiovascular disease risk in prostate cancer survivors receiving androgen deprivation therapy. A systematic review was conducted across PubMed, CINAHL, Embase, and Cochrane CENTRAL. Intervention or observational cohort studies evaluating diets, nutrients, or nutraceuticals with or without concurrent exercise interventions on cardiovascular disease, cardiovascular events, or cardiovascular disease biomarkers in those treated with androgen deprivation therapy were included. Confidence in the body of evidence was appraised using Grading of Recommendations, Assessment, Development and Evaluations. Twelve studies reported across fifteen papers were included. Interventions were heterogenous, with most studies including an exercise co-intervention (n = 8). Few significant findings for the effects of diet on cardiometabolic markers were likely due to weak methodology and sample sizes. Strongest evidence was for the effect of a healthy Western dietary pattern with exercise on improved blood pressure (Confidence: moderate). The healthy Western dietary pattern with exercise may improve high-density lipoprotein cholesterol (Confidence: Low) and flow-mediated dilation. Soy may improve total cholesterol (Confidence: Very low). A low-carbohydrate diet with physical activity may improve high-density lipoprotein cholesterol, incidence of metabolic syndrome, and Framingham cardiovascular disease risk score. Evidence of the effect of dietary interventions on cardiometabolic biomarkers and cardiovascular disease risk of prostate cancer survivors receiving androgen deprivation therapy is insufficient to inform practice. Well-designed dietary interventions aimed at improving cardiometabolic outcomes of this population are warranted to inform future dietary recommendations.

Exploring Adolescent and Young Adult Cancer Survivors' Experience with Cancer Treatment-Related Symptoms: A Qualitative Analysis of Semi-Structured Interviews

Purpose: Few studies have specifically targeted symptom management interventions for adolescent and young adult (AYA) cancer survivors. A greater understanding of AYA cancer survivors' experiences with cancer treatment-related symptoms would help develop age-appropriate oncology symptom management interventions. The purpose of this qualitative analysis was to explore AYA cancer survivors' experience with cancer treatment-related symptoms. Methods: Nineteen post-treatment AYA cancer survivors (18-39 years old) who self-reported moderate-severe cancer treatment-related symptom severity participated in video conferencing or telephone interviews. The questions in the interview guide queried participants to share their experience with cancer treatment-related symptoms. Inductive content analysis was used to identify themes from the interviews. Results: The themes that emerged from the interviews included (1) cancer treatment-related symptoms negatively affected AYA cancer survivors' quality of life (e.g., symptoms served as a reminder of cancer recurrence possibility); (2) AYA cancer survivors' attitudes and feelings about communicating cancer treatment-related symptom concerns to clinicians (e.g., patient-clinician communication was bolstered when AYAs perceived that symptoms were being taken seriously); (3) AYA cancer survivors are interested in oncology symptom management clinical trials, but logistical challenges are barriers to participation; and (4) AYA cancer survivors are interested in nonpharmacological treatments for symptom management. Conclusion: Results highlight the burden of cancer treatment-related symptoms on day-to-day life among post-treatment AYA cancer survivors. Future work is needed to identify nonpharmacological symptom management interventions, strategies to improve patient-clinician communication about symptoms, and strategies to increase the visibility and accessibility of symptom management clinical trials for AYA cancer survivors.

[Key microbial monitoring and clinical analysis of bloodstream infections and CRO colonization after hematopoietic stem cell transplantation in hematological patients]

Objective: To investigate the distribution and clinical characteristics of pathogenic bacteria following hematopoietic stem cell transplantation (HSCT), as well as to provide a preliminary research foundation for key microbial monitoring, and clinical diagnosis and treatment of infections after HSCT in hematological patients. Methods: We retrospectively analyzed the clinical data of 190 patients who tested positive for microbial testing [G-bacteria blood culture and/or carbapenem-resistant organism (CRO) screening of perianal swabs] at our center from January 2018 to December 2022. Patients were divided into blood culture positive, perianal swab positive, and double positive groups based on the testing results. The three patient groups underwent statistical analysis and comparison. Results: The top four pathogenic bacteria isolated from sixty-three patients with G-bacteria bloodstream infection (BSI) were Escherichia coli (28 strains, 43.75% ), Klebsiella pneumonia (26 strains, 40.63% ), Pseudomonas aeruginosa (3 strains, 4.69% ), and Enterobacter cloacae (3 strains, 4.69% ). The top three pathogenic bacteria isolated from 147 patients with CRO perianal colonization were carbapenem-resistant Klebsiella pneumoniae (58 strains, 32.58% ), carbapenem-resistant Escherichia coli (49 strains, 27.53% ), and carbapenem-resistant Enterobacter cloacae (20 strains, 11.24% ). The 3-year disease-free survival (DFS ) and overall survival (OS) of double positive group patients were significantly lower compared to those in the blood culture and perianal swab positive groups (DFS: 35.6% vs 53.7% vs 68.6%, P=0.001; OS: 44.4% vs 62.4% vs 76.9%, P<0.001), while non-relapse mortality (NRM) was significantly higher (50.0% vs 34.9% vs 10.6%, P<0.001). Failed engraftment of platelets and BSI are independent risk factors for NRM (P<0.001). Using polymyxin and/or ceftazidime-avibactam for more than 7 days is an independent protective factor for NRM (P=0.035) . Conclusion: This study suggests that the occurrence of BSI significantly increases the NRM after HSCT in patients with hematological diseases; CRO colonization into the bloodstream has a significant impact on the DFS and OS of HSCT patients.

Differentiating gender-based reproductive concerns among adolescent and young adult cancer patients: A mixed methods study

INTRODUCTION

Few studies have examined the distinct reproductive concerns (RC) of men and women in the adolescent and young adult (AYA) cancer patient population. The purpose of this mixed-methods study was to explore and differentiate the RC of AYAs.

METHODS

Participants completed the Reproductive Concerns After Cancer (RCAC) scale and participated in a semistructured interview. Interviews were deductively coded based on an analytic schema derived from the RCAC.

RESULTS

After identifying participants through the electronic health record, 27 younger AYAs, ages 12-25, enrolled in the study. Four inductive themes emerged and differed by gender. These include differential temporality, acceptance, and openness to alternatives, partner influence, and parental/guardian influence. AYA men reported fewer RC (M = 49.4, SD = 9.6) compared to AYA women (M = 56.8, SD = 8.4).

CONCLUSIONS

Oncofertility care providers are advised to account for short- and long-ranging concerns based on AYAs' gender. Future evaluations of patient-reported outcome measures specific to AYA RC are recommended.

Exploring the Relationship between Self-Rated Health and Unmet Cancer Needs among Sexual and Gender Minority Adolescents and Young Adults with Cancer

This study evaluates the unmet needs of sexual and gender minority (SGM) adolescent and young adult (AYA) cancer survivors by comparing SGM AYA self-rated health (SRH) scores to their non-SGM (i.e., cisgender/heterosexual) counterparts. The Cancer Needs Questionnaire-Young People (CNQ-YP) and self-rated health measures were used to assess unmet needs in AYAs aged 15-39 who had been diagnosed with cancer in the previous ten years (n = 342). Participants were recruited from a National Cancer Institute (NCI) Comprehensive Cancer Center registry using the modified Dillman's method. Self-reported sexual orientation and gender identity (SO/GI) data were collected. Independent t-tests were used to test between-group differences in unmet needs and Pearson's chi-square test was used to determine the difference in SRH scores between SGM and non-SGM AYA cancer survivors. SGM AYA cancer survivors reported greater mean needs than their non-SGM counterparts across all six domains and reported significantly greater needs in the domains of Feelings and Relationships, t(314) = -2.111, p = 0.036, Information and Activities, t(314) = -2.594, p = 0.009, and Education, t(207) = -3.289, p < 0.001. SGM versus non-SGM SRH scores were significantly different, indicating that a higher percentage of SGM AYAs reported poor/fair health compared to those who were non-SGM. Unmet life and activities needs were negatively associated with AYA cancer survivors' SRH, whereas unmet work needs were positively associated with AYA cancer survivors' SRH. An AYA's gender identity (SGM versus non-SGM) was not a moderator. SGM AYAs are an understudied group within an already vulnerable patient population. Unmet psychosocial needs related to one's feelings and relationships, and information and activity needs merit further research to develop tailored interventions that reflect the experiences of SGM AYAs.

Banking on Fertility Preservation: Financial Concern for Adolescent and Young Adult Cancer Patients Considering Oncofertility Services

Purpose: Financial concern is a major issue for adolescent and young adult (AYA) cancer patients. Furthermore, unaddressed oncofertility challenges (e.g., infertility) are linked to psychological distress and decreased overall quality of life. Little is known about how financial concern in terms of oncofertility (i.e., concern regarding affording fertility preservation [FP] services) impacts AYAs' decision making and experiences. Methods: AYA cancer patients (n = 27) aged 12-25 years whose cancer treatment conferred risk of infertility were recruited through electronic health record query. Participants completed semi-structured interviews, which were recorded, transcribed, and deductively coded for themes related to information needs, knowledge of treatment effects on fertility, and reproductive concerns after cancer. Emergent, inductive themes related to financial concern were identified. The Institutional Review Board at the University of Michigan approved this study (HUM#00157267). Results: Financial concern was a dominant theme across the qualitative data. Emergent themes included (1) varied access to health insurance, (2) presence of parental/guardian support, (3) reliance upon financial aid, (4) negotiating infertility risk, and (5) lack of preparation for long-term costs. AYAs relied heavily upon parents for out-of-pocket and insurance coverage support. Some participants sought financial aid when guided by providers. Several participants indicated that no financial support existed for their circumstance. Conclusions: Financial consequences in terms of oncofertility are a major issue affecting AYA cancer patients. The incidence and gravity of financial concern surrounding affording oncofertility services merits attention in future research (measuring financial resources of AYAs' parental/support networks), clinical practice (strategically addressing short- and long-term costs; tailored psychosocial support), and health care policy (promoting legislation to mandate pre- and post-treatment FP coverage).

The Effectiveness of Cognitive Behavioral Therapy for Depression Among Individuals with Diabetes: a Systematic Review and Meta-Analysis

PURPOSE OF REVIEW

Depression is prevalent and common among individuals living with diabetes. The aim of this review is to systematically assess and meta-analyze the treatment effect of cognitive-behavioral therapy for depression (and other affective outcomes) among patients with diabetes.

RECENT FINDINGS

Earlier investigations found both psychosocial and pharmacological interventions, including cognitive-behavioral therapy, were promising in managing depression in patients with diabetes, though these findings remain inclusive due to poor study designs and a small number of trials included, which calls for a comprehensive systematic review and meta-analysis. A total of 33 studies (89 effect sizes) reported a moderate and statistically significant treatment effect of cognitive-behavioral therapy for depressive symptoms among individuals with diabetes (d = 0.301, 95% CI 0.115-0.487, p < 0.001). On average, cognitive-behavioral therapy was effective for psychological stress/distress outcomes but not for anxiety or physiological outcomes. The findings of the study confirmed CBT as an effective treatment option for depression among diabetes patients and identified important areas for future research.

Body image disturbances in adolescent and young adult cancer patients confronting infertility risk and fertility preservation decisions

PURPOSE

Body image is a major psychosocial concern for all cancer patients but can affect the adolescent and young adult (AYA) population in distinct ways. Similarly, the prospect of infertility and the fertility preservation process can create additional stress during cancer treatment. Discussions regarding infertility inherently implicate the body and its reproductive function, but downstream effects on self-perception have not been previously described. The aim of this study was to explore the experiences of AYAs as they considered their risk of infertility and options for fertility preservation (FP), specifically the ways in which this impacted body image and FP decision-making.

METHODS

AYA cancer patients (n = 27) aged 12-25 years whose cancer and treatment conferred risk of infertility were recruited through electronic health record query at an NCI-Designated Comprehensive Cancer Center. Participants completed semi-structured interviews, which were recorded, transcribed, and deductively coded for themes related to information needs, knowledge of treatment effects on fertility, and reproductive concerns after cancer. Emergent, inductive themes related to body image were identified.

RESULTS

Body image concerns, related to both physical appearance and body functioning emerged. Common concerns included anticipating change as it pertains to the body and its functions, physical discomfort, fear of judgment, and meeting expectations of the body. While these themes are broad in nature, they have been previously explored in relation to body image in general and their emergence in the oncofertility space provides guidance for further optimization of infertility and fertility preservation discussions.

CONCLUSIONS

AYA cancer patients experience a multitude of body image related disturbances when faced with the possibility of infertility and fertility preservation. In identifying and exploring these themes, future opportunities for improving oncofertility practice and discussions among AYAs with a focus on body image positivity are called upon.

The relationship between unmet cancer care needs and self-rated health among adolescents and young adults with cancer

BACKGROUND

Adolescents and young adults (AYA) with cancer face unique psychosocial challenges that often impact their outcomes, including self-rated health. To date, few studies have focused on AYA cancer survivors' multidimensional unmet needs of cancer care in relation to their health status.

METHODS/PROCEDURE

This study surveyed 324 AYA cancer survivors in a cross-sectional design using the Cancer Needs Questionnaire - Young People (CNQ-YP). In addition to descriptive statistics and bivariate correlations, multinomial logistic regressions were used for analysis.

RESULTS

AYA cancer survivors' daily life needs were found to be significantly and negatively associated with self-rated health, OR = 0.910, 95% CI 0.843, 0.983, p < 0.01, and OR = 0.888, 95% CI 0.818, 0.966, p < 0.01. In addition, the unmet work needs were significantly and positively associated with participants' self-rated health, OR = 1.207, 95% CI 1.003, 1.452, p < 0.05.

CONCLUSIONS

Moving beyond simply describing the unique psychosocial needs confronting AYA cancer survivors, this study empirically identified two specific dimensions of unmet needs of AYA cancer survivors that were significantly correlated to their SRH, both of which should be considered in future service and intervention research to support AYAs with cancer.

Acute myocardial infarction and myocarditis following COVID-19 vaccination

Emerging reports raise concerns on the potential association between the COVID-19 vaccines and cardiac manifestations. We sought to evaluate cardiac complications associated with COVID-19 vaccination in a pooled analysis from our institution's cohort study and systematic review. Consecutive patients admitted to a tertiary hospital in Singapore between 1 January 2021 and 31 March 2021, with the onset of cardiac manifestations within 14 days following COVID-19 vaccination, were studied. Furthermore, a systematic review was performed, with PubMed, Embase, Research Square, MedRxiv and LitCovid databases accessed from inception up to 29 June 2021. Relevant manuscripts reporting individual patient data on cardiac complications following COVID-19 vaccination were included. Thirty patients were included in the study cohort, with 29 diagnosed with acute myocardial infarction (AMI) and 1 with myocarditis. Five patients developed heart failure, two had cardiogenic shock, three intubated, and one had cardiovascular-related mortality. In the systematic review, 16 studies were included with 41 myocarditis and 6 AMI cases. In the pooled analysis of the study cohort and the systematic review, 35 patients had AMI and 42 had myocarditis. Majority were men, and myocarditis patients were younger than AMI patients. Myocarditis patients tended to present 72 h postvaccination, while AMI patients were older and typically presented 24 h postvaccination. Majority with AMI or myocarditis developed symptoms after the first and second vaccination dose, respectively. This pooled analysis of patients presenting with cardiac manifestations following COVID-19 vaccination highlights the differences between myocarditis and AMI presentations in temporal association with the vaccination.

Robotic versus laparoscopic left colectomy with complete mesocolic excision for left-sided colon cancer: a multicentre study with propensity score matching analysis

BACKGROUND

Robotic surgery for right-sided colon and rectal cancer has rapidly increased; however, there is limited evidence in the literature of advantages of robotic left colectomy (RLC) for left-sided colon cancer. The purpose of this study was to compare the outcomes of RLC versus laparoscopic left colectomy (LLC) with complete mesocolic excision (CME) for left-sided colon cancer.

METHODS

Patients who had RLC or LLC with CME for left-sided colon cancer at 5 hospitals in China between January 2014 and April 2022 were included. A one-to-one propensity score matched analysis was performed to decrease confounding. The primary outcome was postoperative complications occurring within 30 days of surgery. Secondary outcomes were disease-free survival, overall survival and the number of harvested lymph nodes.

RESULTS

A total of 292 patients (187 males; median age 61.0 [20.0-85.0] years) were eligible for this study, and propensity score matching yielded 102 patients in each group. The clinical-pathological characteristics were well-matched between groups. The two groups did not differ in estimated blood loss, conversion to open rate, time to first flatus, reoperation rate, or postoperative length of hospital stay (p > 0.05). RLC was associated with a longer operation time (192.9 ± 53.2 vs. 168.9 ± 52.8 minutes, p=0.001). The incidence of postoperative complications did not differ between the RLC and LLC groups (18.6% vs. 17.6%, p = 0.856). The total number of lymph nodes harvested in the RLC group was higher than that in the LLC group (15.7 ± 8.3 vs. 12.1 ± 5.9, p< 0.001). There were no significant differences in 3-year and 5-year overall survival or 3-year and 5-year disease-free survival.

CONCLUSIONS

Compared to laparoscopic surgery, RLC with CME for left-sided colon cancer was found to be associated with higher numbers of lymph nodes harvested and similar postoperative complications and long-term survival outcomes.

A Clinical Case Study of Solution-Focused Brief Therapy for Young Adult Cancer Patients’ Psychological Distress: Focusing on Positive Emotions

Psychological distress is highly prevalent among adolescent and young adult (AYA) cancer patients, an age-defined population (15–39) disproportionately impacted by their cancer diagnosis. Solution-focused brief therapy (SFBT) is a strength-based and evidence-supported approach for youth with medical conditions. The use of SFBT in young cancer patients, however, has been rarely described. Building on the broaden-and-build theory of positive emotions, this study describes how SFBT clinicians intentionally foster positive emotions, especially hope, in an AYA cancer patient to foster therapeutic change. We found improvements in the patient’s psychological distress as well as growth in levels of hope both in the immediate post-intervention assessment and in the 2-week follow-up. The findings of the study suggested that SFBT is a promising approach to the unique challenges confronting AYAs with cancer. It was not feasible for this case study to match the sex and racial identities for a therapist with the client’s preference, which is considered a main limitation of this study.

Entertain Me Well: An Entertaining, Tailorable, Online Platform Delivering CBT for Depression

Depression prevalence is high, impacting approximately 20% of Americans during their lifetime, and on the rise due to stress and loss associated with the COVID-19 pandemic. Despite the high prevalence of depression, unacceptable treatment access disparities persist. When depression goes untreated, it leads to substantial negative impacts in multiple life domains. Cognitive behavioral therapy (CBT), the gold-standard psychosocial treatment for depression, remains largely unavailable to individuals living with depression, particularly individuals who are members of underrepresented groups in our society. Digital mental health interventions (DMHI) have led to important advances in extending the reach of CBT for depression; however, they are underutilized and treatment engagement remains low. We sought to address some of the current gaps in DMHI by developing an online platform for delivering CBT for depression that is entertaining, simple and straightforward, and tailorable. First, this article introduces our online platform, Entertain Me Well (EMW) and its key innovations, including the use of an engaging, character-driven storyline presented as "episodes" within each session, as well as customizable content that allows for tailoring of text, images, and examples to create content most relevant to the target client population, context, or setting. Next, we describe two EMW depression treatment programs that have been tailored: one for delivery in the rural church setting, called Raising Our Spirits Together, and one tailored for delivery in dialysis centers, called Doing Better on Dialysis. Finally, we discuss future directions for the EMW platform, including the ability to create programs for other common mental health and health conditions, the development of additional character-driven storylines with greater treatment personalization, translation of content in multiple languages, and the use of additional technological innovation, such as artificial intelligence like natural language processing, to enhance platform interactivity.

Social Wellbeing in Cancer Survivorship: A Cross-Sectional Analysis of Self-Reported Relationship Closeness and Ambivalence from a Community Sample

Improvements in early screening and treatment have contributed to the growth of the number of cancer survivors. Understanding and mitigating the adverse psychosocial, functional, and economic outcomes they experience is critical. Social wellbeing refers to the quality of the relationship with partners/spouses, children, or significant others. Close relationships contribute to quality of life and self-management; however, limited literature exists about social wellbeing during survivorship. This study examined positive and negative self-reported changes in a community sample of 505 cancer survivors. Fourteen items assessed changes in communication, closeness with partner/children, stability of the relationship, and caregiving burden. An exploratory factor analysis was conducted using a robust weighted least square procedure. Differences by sociodemographic and clinical characteristics were investigated. Respondents were mostly male, non-Hispanic white, and ≥4 years since diagnosis. Two factors, labeled Relationship Closeness and Ambivalence, emerged from the analysis. Women, younger survivors, individuals from minority groups, and those with lower income experienced greater negative changes in social wellbeing. Variations by treatment status, time since diagnosis, and institution were also reported. This contribution identifies groups of cancer survivors experiencing affected social wellbeing. Results emphasize the need to develop interventions sustaining the quality of interpersonal relationships to promote long-term outcomes.

Education Moderates the Association between Depressive Symptoms and Self-Rated Health among Older Adults with Cancer

This study examined the association between depressive symptoms and self-rated health (SRH) and whether and how such association varies by education among older adults with cancer. Data came from the 2019 National Health Interview Survey. A total of 2,470 participants aged 65 or older who had been diagnosed with cancer by a doctor or other health professional were included in this study. Ordinal logistic regression was used to examine the association between depressive symptoms and SRH and whether and how such association varies by education among older adults with cancer. More depressive symptoms were associated with worse SRH. Such association became stronger with higher education among older adults with cancer. Findings confirm the associations between depressive symptoms and SRH among older adults with cancer. The differential impact of education on SRH and on the association between depressive symptoms and SRH highlights the importance of considering patients' educational attainment in a more comprehensive way when working with older adults with cancer. When conducting distress screening among cancer survivors, oncology social workers should be aware of the complex relationship between education and depression in relation to cancer survivors' SRH.

Higher long-term mortality in patients with concomitant acute coronary syndrome and aortic stenosis

Background

Aortic stenosis (AS) and acute coronary syndrome (ACS) share similar cardiovascular risk factors, and their concomitant presentation is increasing in incidence with the aging population. Yet literature regarding the prognosis of patients with concomitant ACS and AS remains scarce.

Methods

This retrospective cohort study examined consecutive patients presenting with ACS (ST-segment elevation myocardial infarction [STEMI] and non-STEMI [NSTEMI]) and concomitant AS between 1 January 2011 and 31 March 2021 in a tertiary hospital. The cohort was divided into mild, moderate and severe AS based on index echocardiogram. The primary outcome was all-cause mortality. Kaplan-Meier curves were constructed to compare all-cause mortality among the three groups of patients, based on ACS type and left ventricular ejection fraction (LVEF). Multivariable Cox regression was performed to identify independent predictors of all-cause mortality.

Results

Of a total of 563 patients, 264 had mild (46.9%), 193 moderate (34.3%) and 106 severe AS (18.8%). The mean follow-up duration was 2.5 (± 2.4) years. Majority of patients (72.5%) presented with NSTEMI. Patients with moderate and severe AS had higher rates of all-cause mortality compared to those with mild AS (49.7% vs. 51.4% vs. 35.6% respectively, p=0.002). Concomitant moderate (HR 1.439, 95% CI 1.012–2.048, p=0.043) and severe AS (HR 1.844, 95% CI 1.159–2.933, p=0.010) were independent predictors of all-cause mortality after adjusting for age, gender, LVEF, ACS type, chronic kidney disease, diabetes, hypertension, coronary artery bypass grafting and aortic valve replacement as a time-dependent variable. The Kaplan-Meier curves demonstrated excess mortality in moderate and severe AS, compared to the mild AS group (p&lt;0.001), with similar survival trends observed in the STEMI and the NSTEMI groups, as well as those with preserved LVEF.

Conclusion

Regardless of the ACS presentation type, long-term excess mortality in those with concomitant moderate or severe AS was observed. The adverse prognosis typically observed in patients with concomitant severe AS, in the setting of ACS, extends to patients with moderate AS.

Prognostically distinct phenotypes of metabolic health beyond obesity in aortic stenosis

Background

Whilst current evidence are in favour of metabolic health and non-obesity in the reduction of incident cardiovascular disease, little is known regarding the prognosis across the metabolic phenotypes once cardiovascular disease occurs. This study examined the prognosis of patients with significant aortic stenosis (AS) based on the presence of metabolic health and obesity.

Methods

This retrospective cohort on consecutive patients presenting with moderate-to-severe AS to a tertiary hospital between 2010 and 2015. Patients were allocated into 4 groups based on obesity and metabolic health: metabolically healthy obese (MHO), metabolically healthy non-obese (MHNO), metabolically unhealthy obese (MUO) and metabolically unhealthy non-obese (MUNO). Metabolic health was defined in accordance to Program Adult Treatment Panel III criteria. The primary outcome was all-cause mortality. Cox regression examined independent associations between mortality and metabolic phenotypes, adjusting for aortic valve area, ejection fraction, age, sex, chronic kidney disease and AVR as a time-dependent covariate.

Results

Of 727 patients, the majority (51.6%) were MUNO, followed by MUO (32.7%), MHNO (11.4%), and MHO (4.3%). MHNO had the highest mortality (43.0%), followed by the MUNO (37.5%), MUO (30.0%) and MHO (6.9%) groups (p=0.001). Compared to MHNO, MHO (HR 0.159, 95% CI 0.038–0.668, p=0.012) and MUO (HR 0.614, 95% CI 0.403–0.937, p=0.024) were independently associated with lower all-cause mortality rates, after adjusting for confounders. In obese patients, metabolic health had favourable survival compared to metabolically unhealthy (p=0.015), but this protective impact of metabolic health was not observed in overweight or normal weight individuals. Obesity had favourable survival compared to overweight and normal weight, in both metabolically health (p=0.002) and unhealthy (p=0.007) patients,

Conclusion

MHO patients with AS have the most favourable prognosis whilst the seemingly healthy MHNO group had the worst survival. There should be a paradigm shift towards prioritising metabolic health rather than weight reduction in patients with significant AS.

Age as a moderator for the association between depression and self-rated health among cancer survivors: a U.S. based population study

BACKGROUND

Self-rated health (SRH) is a salient outcome for cancer survivors. Although depression is a well-studied correlate with SRH, few studies have focused on the role of cancer survivors' age on the association between depression and SRH. This study evaluates demographic and psychosocial factors associated with cancer survivors' SRH. We also assess the moderating role of age to the association between depression and SRH.

MATERIALS AND METHODS

This paper analyzed 2,470 U.S. cancer survivors from the 2019 National Health Interview Survey. Two ordered logistic regression models with complex survey weights were used for analyses. Missing data was addressed using multiple imputations by chained equations.

RESULTS

Being female, higher education and higher income were positively associated with better SRH. While the relationship between higher education and higher income was consistent with previous findings, the positive association between being female and SRH was different from previous studies. Age significantly moderated the association between depression and SRH, evidenced by results of the joint tests of all interaction term coefficients being statistically significant, F(2, 544.6) = 5.13, p < 0.01.

CONCLUSIONS

The findings of the study highlighted the significance of screening for social determinants of health and health disparity when supporting cancer survivors. Additionally, findings of this study emphasized the significance of adopting an age-specific approach when evaluating and addressing depression across different age groups of cancer survivors.

For whom and what outcomes does cognitive-behavioral-therapy work among cancer survivors: a systematic review and meta-analysis

OBJECTIVE

To perform a systematic review and meta-analysis of CBT for individuals diagnosed with cancer across a broad range of outcome domains, i.e., functional health, psychological health, health behaviors, social relational, and general wellness.

METHODS

A comprehensive search of 7 databases, 91 published reviews, and 4 professional websites was performed on August 30th, 2021. English-language clinical trials of CBT for cancer patients/survivors were included. Studies were independently screened, and data were extracted by 2 reviewers, and discrepancies were resolved by consensus among the investigative team. A total of 151 clinical trials (154 articles) published between 1986 and 2021 were included in the analysis.

RESULTS

CBT was overall effective for cancer patients/survivors in the domains of functional health, g = 0.931, p < 0.001, psychological health, g = 0.379, p < 0.001, and general wellness, g = 0.257, p < 0.001, but ineffective in domains of health behaviors, g = 0.792, p > 0.05, and social relational outcomes, g = 0.319, p > 0.05. Additional subgroup and moderator analyses further revealed CBT's differential treatment effect for different within domain outcomes, across different cancer disease stages, and CBT delivery format.

CONCLUSIONS

Findings of the study showed that CBT is an effective treatment for individuals diagnosed with cancer. However, treatment effects differ by important disease- and intervention-related factors, which should be considered when recommending CBT for cancer patients/survivors.

"Queer Insights": Considerations and Challenges for Assessing Sex, Gender Identity, and Sexual Orientation in Oncofertility Research

This article addresses issues related to clinical and research approaches to oncofertility for adolescent and young adult (AYA) sexual and gender minority (SGM) cancer patients. Limited attention has been dedicated to understanding the extent to which oncofertility services are appropriately and equitably delivered to AYAs with diverse orientations toward sexual orientation, gender identity, and future family. Unresolved challenges to conducting research with this vulnerable population perpetuate a lack of adequate knowledge about SGM AYA oncofertility needs. Therefore, the purpose of this paper is to inform considerations of sex, gender identity, and sexual orientation for investigations that include SGM AYAs. In order to improve the knowledge base and clinical services for this population, we discuss (1) challenges to sampling this population; (2) categorization and survey logic (e.g., skip patterns) in light of fluid sexual orientation and gender identities; and (3) clinical implications of accurately assessing sex and gender for oncofertility research and practice. We also recommend strategies for producing inclusive and accurate assessments of sexual and gender identity categories in both research and clinical encounters with SGM AYAs. Incorporating "queer insights" into empirical research - that is, positioning queer theory at the center of oncofertility study design - is suggested as a future direction for oncofertility research and practice.

A scintillator attenuation spectrometer for intense gamma-rays

A new type of compact high-resolution high-sensitivity gamma-ray spectrometer for short-pulse intense gamma-rays (250 keV to 50 MeV) has been developed by combining the principles of scintillators and attenuation spectrometers. The first prototype of this scintillator attenuation spectrometer (SAS) was tested successfully in Trident laser experiments at LANL. Later versions have been used extensively in the Texas Petawatt laser experiments in Austin, TX, and more recently in OMEGA-EP laser experiments at LLE, Rochester, NY. The SAS is particularly useful for high-repetition-rate laser applications. Here, we give a concise description of the design principles, capabilities, and sample preliminary results of the SAS.

Study protocol: A randomized controlled trial of Raising Our Spirits Together, an entertaining, group-based technology-assisted cognitive behavioral therapy for depression, tailored for rural adults and delivery by clergy

This paper presents a methodological description of a randomized controlled trial (RCT) testing the effect of Raising Our Spirits Together (ROST), a technology-assisted cognitive behavioral therapy (T-CBT) for depression, tailored for the rural context and for delivery by clergy, compared to an enhanced control condition. Depression is among the most common mental health conditions; yet the majority of adults with depression do not receive needed treatment due to limited access to mental health professionals, treatment-associated costs, distance to care, and stigma. These barriers are particularly salient in rural areas of the United States. T-CBT with human support is an accessible and effective treatment for depression; however, currently available T-CBTs have poor completion rates due to the lack of tailoring and other features to support engagement. ROST is a T-CBT specifically tailored for the rural setting and delivery by clergy, who are preferred, informal providers. ROST also presents core CBT content in a simple, jargon-free manner that supports multiple learning preferences. ROST is delivered virtually in a small group format across 8 weekly sessions via videoconferencing software consistent with other clergy-based programs, such as Bible studies or self-help groups. In this study, adults with depressive symptoms recruited from two rural Michigan counties will be randomized to receive ROST versus an enhanced control condition (N = 84). Depressive symptoms post-treatment and at 3 months follow-up according to the Patient Health Questionnaire (PHQ-9) will be the primary outcome. Findings will determine whether ROST is effective for improving depression symptoms in underserved, under resourced rural communities.

OP0015 PROINFLAMMATORY MONOCYTES AND MACROPHAGES IN SYNOVIAL FLUID AND BURSAL TISSUE OF PATIENTS WITH POLYMYALGIA RHEUMATICA: POTENT PRODUCERS OF IL-6 AND GM-CSF

Background

Polymyalgia rheumatica (PMR) is a common, rheumatic inflammatory disease. Inflammation of bursae and tendon sheaths is a characteristic finding in patients with PMR. Glucocorticoid treatment remains the mainstay treatment for PMR. A study published in 1996 reported that macrophages dominate the inflammatory infiltrates in the glenohumeral synovium of PMR patients1, suggesting the importance of these cells in the immunopathology of PMR. However, the functional and phenotypical heterogeneity of the tissue-infiltrating macrophages in PMR remains obscure. Although treatment with anti-IL-6 receptor (tocilizumab) has shown promising results2, it is unclear whether macrophages contribute to IL-6 production in PMR. Additionally, anti-GM-CSF receptor therapy (mavrilimumab), recently shown to be efficacious in the closely related disease giant cell arteritis3, may also be useful for the treatment of PMR. Knowledge on the functional heterogeneity of monocytes/macrophages in PMR may aid in identifying novel therapeutic targets for this condition.

Objectives

To determine the phenotype of monocyte/macrophages in peripheral blood, bursal/tenosynovial fluid and bursal tissue of patients with PMR.

Methods

Paired peripheral blood (PB), bursal/tenosynovial fluid (SF) and bursal tissue biopsy samples from 11 PMR patients were included in our study. Bursal and tenosynovial samples were obtained from the shoulder. Distribution of the monocyte subsets (classical, intermediate and non-classical monocytes) was determined based on the level of CD14 and CD16 expression by flow cytometry. To study monocyte activation status, markers of ‘M1’ like (CD80 and CD64) and ‘M2’ like (CD206 and FRβ) macrophage polarization were included in the flow cytometry analysis. Immunohistochemistry of bursal tissue biopsies was focused on macrophage markers (CD68, CD86, CD64, CD206 and FRβ) andproinflammatory cytokines (IL-6 and GM-CSF), which were scored semi-quantitatively. Double immunofluorescence stainings were performed to determine the expression of IL-6 and GM-CSF by tissue-infiltrating macrophages in bursal tissue.

Results

Monocytes were detected in the SF of PMR patients. The proportion of classical monocytes was significantly lowered (p=0.001) in SF versus PB, while the proportion of intermediate monocytes was significantly elevated (p=0.001). The expression of CD206 was significantly elevated (p=0.001) but not FRβ in SF monocytes, suggesting GM-CSF skewed phenotype. In bursal tissue, macrophages displayed mixed ‘M1’/’M2’ traits with high expression of all macrophage polarization markers. Proinflammatory cytokines IL-6 and GM-CSF were highly expressed throughout the bursal tissue biopsies. Double immunofluorescence staining confirmed the expression of IL-6 and GM-CSF by the infiltrating macrophages.

Conclusion

SF monocytes and bursal tissue macrophages show a pro-inflammatory phenotype in PMR. Moreover, tissue-infiltrating macrophages show a prominent IL-6 and GM-CSF response in PMR. Our data add to the rationale of targeting IL-6 and GM-CSF as treatment options in PMR.

National trends in non-fatal suicidal behaviors among adults in the USA from 2009 to 2017

BACKGROUND

The age-adjusted rate of suicide death in the USA has increased significantly since 2000 and little is known about national trends in non-fatal suicidal behaviors (ideation, plan, and attempt) among adults and their associated sociodemographic and clinical characteristics. This study examined trends in non-fatal suicidal behaviors among adults in the USA.

METHODS

Data were obtained from adults 18-65 years of age who participated in the National Survey on Drug Use and Health (NSDUH), including mental health assessment, from 2009 to 2017 (n = 335 359). Examinations of data involved trend analysis methods with the use of logistic regressions and interaction terms.

RESULTS

Suicidal ideation showed fluctuation from 2009 to 2017, whereas suicide plan and attempt showed significantly positive linear trends with the odds increasing by an average of 3% and 4%, respectively. Suicide plan increased the most for females and adults ages 18-34, and attempt increased the most for adults with drug dependence. Both plan and attempt increased the most among adults who either had mental illness but were not in treatment or had no mental illness.

CONCLUSIONS

Given attempted suicide is the strongest known risk factor for suicide death, reducing non-fatal suicidal behaviors including attempt are important public health and clinical goals. The interactional findings of age, sex, mental health status, and drug dependence point toward the importance of tailoring prevention efforts to various sociodemographic and clinical factors.

Thermal Analysis of PE Extended Chain Crystal of PE Extended Chain Crystal from Gel Spinning

It has been recognized that ultra-high strength and high modulus ultra-highly drawn Polyethylene (PE) fiber is produced from the formation of extended chain crystal. Nevertheless, whether extended chain crystal exists in gel spinning ultra-highly drawn PE fiber is still an unsettled question. In this work, decalin was adopted as a solvent for PE gel spinning. By means of thermal analysis, X-ray diffraction methods etc, the existence of extended chain crystal was explored. Reasons for confusion in previous studies of this problem were discussed.

In PE fiber from 3 wt-°/o dope, extended chain crystal starts to form during draw ratios over 20. When draw ratio equals 42, the content of extended chain crystal roughly equals that of folded chain crystal. The melting point of extended chain crystal is 6°C higher than that of folded chain crystal. They are 145.5° C and 150° C to 152.5° C respectively. The latter would slightly rise with arise of draw ratio.

Multi-crystallization behavior of annealed PE fiber was determined and discussed. It was also confirmed that there is a linear logarithm relationship between thermal shrinkage (internal stresses) and fiber moduli.

Technology-Assisted Psychosocial Interventions for Childhood, Adolescent, and Young Adult Cancer Survivors: A Systematic Review and Meta-Analysis

Purpose: Technology-assisted interventions are essential in supporting cancer survivors' psychosocial outcomes, especially for childhood, adolescent, and young adult (AYA) cancer survivors, a tech-savvy generation. This study aims to systematically evaluate review and meta-analyze technology-assisted interventions for childhood and AYA cancer survivors. Methods: Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, the study team used a pre-set of key words and searched studies across 11 electronic databases and 4 professional websites, and conducted a manual search of reference lists from published reviews. Meta-analysis of small sample size corrected Hedges' g was conducted using meta-regression with robust variance estimation. Results: Final analysis included a total of 28 clinical trials, including 237 effect sizes reported an overall statistically significant treatment effect of technology-assisted psychosocial interventions for childhood and AYA cancer survivors, g = 0.382, 95% confidence interval (CI) 0.243 to 0.521, p < 0.0001. Subgroup analysis revealed that distraction-based interventions and interventions for psychosocial and emotional health were overall statistically significant, whereas interventions for childhood and AYA cancer survivors' cancer knowledge outcomes and physical and functional health outcomes were statistically nonsignificant. Moderator analysis found intervention target was a significant moderator. Conclusions: Technology-assisted interventions for childhood and AYA cancer survivors were overall effective across domains of survivorship outcomes. Favorable evidence was found primarily for childhood cancer survivors with limited support for AYA cancer survivors. Implications for Cancer Survivors: Although existing technology-assisted interventions are overall promising, research support for cancer survivors from different age groups and with different psychosocial challenges varies and should be considered individually.

Technology-Assisted, Group-Based CBT for Rural Adults' Depression: Open Pilot Trial Results

PURPOSE

This pilot study assesses the association of Raising Our Spirits Together (ROST), a technology-assisted, group-based cognitive behavioral therapy for depression, with rural adults' depressive symptoms and anxiety.

METHOD

Nine adults from rural Michigan participated in an open pilot of ROST. Clergy facilitated pilot groups. The pilot began in February 2020 in-person. Due to COVID-19, the pilot was completed virtually.

RESULTS

Mean depressive symptom scores, based on the PHQ-9, significantly decreased from pre-treatment (M = 14.4) to post-treatment (M = 6.33; t (8) = 6.79; P < .001). Symptom reduction was maintained at 3-month follow-up (M = 8.00), with a significant pattern of difference in depressive symptoms over time (F(2) = 17.7; P < .001; eta-squared = .689). Similar patterns occurred for anxiety based on the GAD-7. Participants attended an average of 7.33 of 8 sessions. Fidelity ratings were excellent.

DISCUSSION

ROST is a potentially feasible intervention for rural adults' depressive symptoms. ROST offers a promising model for increasing treatment access and building capacity in rural areas.

Evidence for X(3872) in Pb-Pb Collisions and Studies of its Prompt Production at sqrt[s_{NN}]=5.02 TeV

The first evidence for X(3872) production in relativistic heavy ion collisions is reported. The X(3872) production is studied in lead-lead (Pb-Pb) collisions at a center-of-mass energy of sqrt[s_{NN}]=5.02  TeV per nucleon pair, using the decay chain X(3872)→J/ψπ^{+}π^{-}→μ^{+}μ^{-}π^{+}π^{-}. The data were recorded with the CMS detector in 2018 and correspond to an integrated luminosity of 1.7  nb^{-1}. The measurement is performed in the rapidity and transverse momentum ranges |y|<1.6 and 15<p_{T}<50  GeV/c. The significance of the inclusive X(3872) signal is 4.2 standard deviations. The prompt X(3872) to ψ2S yield ratio is found to be ρ^{Pb-Pb}=1.08±0.49(stat)±0.52(syst), to be compared with typical values of 0.1 for pp collisions. This result provides a unique experimental input to theoretical models of the X(3872) production mechanism, and of the nature of this exotic state.

Evaluating an engaging and coach-assisted online cognitive behavioral therapy for depression among adolescent and young adult cancer survivors: A pilot feasibility trial

OBJECTIVES

Technology-assisted Cognitive Behavioral Therapy (tCBT) has significant potentials to provide engaging and accessible depression treatment for adolescents and young adults (AYAs) coping with cancer. This study evaluated the feasibility and preliminary efficacy of an engaging and tailorable tCBT - Mind Your Total Health (MYTH) - for AYA cancer survivors' depression.

METHODS

Seventeen AYAs diagnosed with cancer were randomly assigned to either the intervention (MYTH) or control group. The intervention group (n = 10) received eight weekly 30-35 minutes coach-assisted tCBT (MYTH), while the control group (n = 7) received active control, BeatingtheBlues (BtB).

RESULTS

Eight out of ten participants in the MYTH group completed at least six out of eight sessions, suggesting strong feasibility (80% completion rate) among AYAs with cancer. Efficacy outcomes indicated that participants in the MYTH group reported significant pre- and post-treatment reduction in depression, t(9) = 5.25, p < 0.001, and anxiety, t(9)=5.07, p < 0.001. Notably, participants in the MYTH group reported significantly lower post-treatment depression than participants in the BtB group, t(15) = 2.40, p < 0.05. The between-group difference reflected a significant between-group treatment effect size, d = 1.12, p < 0.05.

DISCUSSION

This engaging, tailorable, and coach-assisted tCBT intervention is promising in alleviating depression and anxiety among AYA cancer survivors. Future research needs to include larger sample size and a more diverse patient population.

The Association Between Post-Traumatic Stress and Depressive Symptoms Among Older Puerto Ricans in Boston: How Does Loneliness Matter?

OBJECTIVES

To examine the association between post-traumatic stress and depression and whether such an association differs by level of loneliness among older Puerto Ricans.

METHODS

Data were collected from 304 Puerto Ricans aged 60 and above living in the Greater Boston area who responded to questionnaires. We used ordinary least squares regression to examine the association between post-traumatic stress, loneliness, and depressive symptoms.

RESULTS

Post-traumatic stress was significantly associated with higher levels of depression. The association between post-traumatic stress and depression was stronger for those experiencing a higher degree of loneliness.

DISCUSSION

In working with older Puerto Ricans experiencing post-traumatic stress, it is important for mental health professionals to incorporate the assessment of loneliness and to prevent and reduce comorbid depression by addressing loneliness through improving social skills, enhancing social support, and reducing maladaptive social cognition.

An application research for near-surface repository of strontium-90 sorption kinetic model on mudrocks

In this study,90Sr was used as the test radionuclide to characterize the sorption kinetics and effects of initial 90Sr activity and remaining 90Sr in solid concentration were simulated for a near-surface repository. The study focused on the sorption characteristics of radionuclides in unsaturated groundwater environment (or vadose zone) is the important information for investigating the near-surface disposal of intermediate and low-level radioactive waste (ILLW). Moreover, the 90Sr sorption experiments reached equilibrium within 56 h, which fit to the first order sorption kinetic model, and the remaining 90Sr in mudrock samples showed obvious sorption equilibrium hysteresis, which fit to the second order sorption kinetic model. Before reaching the maximum sorption capacity, the sorption rate constant increases with 90Sr increasing; the distribution coefficient (Kd) of 56 h decreases with the remaining 90Sr decreasing. In addition, it showed that the slow sorption process dominated before the sorption reaches equilibrium. In fact, a reliable safety assessment methodology for on-going near-surface repository required a lot of the radionuclides parameters with local environment including the radionuclides sorption/desorption rate constant and maximum sorption capacity.

Association Between Post-Traumatic Stress and Depression Among Older Puerto Ricans: How Does Loneliness Matter?

Puerto Ricans have a significantly higher prevalence of post-traumatic stress disorder (PTSD) than other racial and ethnic groups. PTSD can lead to co-morbid depression, which exacerbates the risk for compromised mental and physical health among older adults. Loneliness, a robust indicator of poor social support, is likely to worsen the dysphoric symptoms of PTSD and increase the risks of depression. However, few studies have focused on the moderating role of loneliness on the association between post-traumatic stress and depression. This study examines the association between post-traumatic stress and depression and whether such an association differs by loneliness among older Puerto Ricans. Data were collected from 304 Puerto Ricans aged 60-81 living in the Greater Boston area who responded to questionnaires in a survey. We used ordinary least squares regression to examine the association between post-traumatic stress, loneliness, and depression. We found that post-traumatic stress was significantly associated with higher levels of depression; however, the association was contingent on experiences of loneliness. The association between post-traumatic stress and depression was stronger for those experiencing a higher degree of loneliness. Findings underscored the role that loneliness plays in exacerbating the risk of developing co-morbid PTSD and depression among older Puerto Ricans. In working with older Puerto Ricans experiencing post-traumatic stress, it is important for mental health professionals to incorporate the assessment of loneliness and to prevent and reduce co-morbid depression by addressing loneliness through improving social skills, enhancing social support, and reducing maladaptive social cognition.

A longitudinal study examining the associations of bullying victimization and suicidal ideation among sexual minority adolescents

INTRODUCTION

Roughly one-third of sexual minority adolescents (SMA) report at least one lifetime suicide attempt. Supportive connections are protective for ideation, yet little is known about this association with SMA-especially longitudinally.

METHODS

Five-step logistic regressions examined the associations of bullying, SMA, and ideation, and also how connectedness mediates this from age 9 and 15 (Fragile Families and Child Wellbeing Study; N = 3,023 adolescents).

RESULTS

At age 9, SMA reported higher levels of daily bullying compared with heterosexual peers (26% versus 14%), and at age 15, SMA reported daily (7%) and weekly (20%) bullying. SMA (32%) reported ideation compared with their heterosexual peers (13%) at age 15. Parental and school connectedness protected adolescents regardless of sexual orientation for SI, but parental attachment buffered the effect of SMA ideation more than school connectedness.

CONCLUSION

Impressing upon schools to be mindful of bullying on their campuses, especially of SMA, is crucial for suicide prevention as we found heterosexual students connected to their school were protected from ideation, yet this was not found for SMA. Strong parent-child bonds can mediate the effects of bullying while at school, speaking to the importance of having at least one trusted adult in an adolescent's life.

Robust Evaluation of Ultraviolet-C Sensitivity for SARS-CoV-2 and Surrogate Coronaviruses

UV light, more specifically UV-C light at a wavelength of 254 nm, is often used to disinfect surfaces, air, and liquids. In early 2020, at the cusp of the COVID-19 pandemic, UV light was identified as an efficient means of eliminating coronaviruses; however, the variability in published sensitivity data is evidence of the need for experimental rigor to accurately quantify the effectiveness of this technique. In the current study, reliable and reproducible UV techniques have been adopted, including accurate measurement of light intensity, consideration of fluid UV absorbance, and confirmation of uniform dose delivery, including dose verification using an established biological target (T1UV bacteriophage) and a resistant recombinant virus (baculovirus). The experimental results establish the UV sensitivity of SARS-CoV-2, HCoV-229E, HCoV-OC43, and mouse hepatitis virus (MHV) and highlight the potential for surrogate viruses for disinfection studies. All four coronaviruses were found to be easily inactivated by 254 nm irradiation, with UV sensitivities of 1.7, 1.8, 1.7, and 1.2 mJ/cm2/log10 reduction for SARS-CoV-2, HCoV-229E, HCoV-OC43, and MHV, respectively. Similar UV sensitivities for these species demonstrate the capacity for HCoV-OC43, HCoV-229E, and MHV to be considered surrogates for SARS-CoV-2 in UV-inactivation studies, greatly reducing hazards and simplifying procedures for future experimental studies. IMPORTANCE Disinfection of SARS-CoV-2 is of particular importance due to the global COVID-19 pandemic. UV-C irradiation is a compelling disinfection technique because it can be applied to surfaces, air, and water and is commonly used in drinking water and wastewater treatment facilities. UV inactivation depends on the dose received by an organism, regardless of the intensity of the light source or the optical properties of the medium in which it is suspended. The 254 nm irradiation sensitivity was accurately determined using benchmark methodology and a collimated beam apparatus for four coronaviruses (SARS-CoV-2, HCoV-229E, HCoV-OC43, and MHV), a surrogate indicator organism (T1UV), and a resistant recombinant virus (baculovirus vector). Considering the light distribution across the sample surface, the attenuation of light intensity with fluid depth, the optical absorbance of the fluid, and the sample uniformity due to mixing enable accurate measurement of the fundamental inactivation kinetics and UV sensitivity.

Change in worry over time among Hispanic women with thyroid cancer

PURPOSE

The purpose of this study is to assess change in worry over time in Hispanic women with thyroid cancer.

METHODS

Worry about recurrence, quality of life, family at risk, death, and harm from treatments was assessed in 273 Hispanic women with thyroid cancer diagnosed in 2014-2015. Subjects were recruited from Surveillance, Epidemiology, and End Results (SEER) Los Angeles. Participants were surveyed at two points in time (time 1: 2017-2018 and time 2: 2019). Multivariable logistic regression was used to determine correlates with high worry (somewhat, quite a bit, very much) versus low worry (not at all, a little) at time 2.

RESULTS

For the five worry items, 20.1-39.6% had high worry at both time 1 and time 2. An additional 7.6-13.4% had low worry at time 1 that became high worry at time 2. In multivariable logistic regression controlling for age, recurrence status, education level, and number of complications or side effects symptoms, younger age (20-39) as compared to older (40-79) was associated with high worry about thyroid cancer recurrence (OR 2.16, 95% CI 1.12-4.17). History of recurrent or persistent disease was associated with high worry about harms from treatment (OR 2.94, 95% CI 1.29-6.67). Greater number of complications or side effects of symptoms was associated with more worry across all five items.

CONCLUSIONS

Some Hispanic women with thyroid cancer have persistently high worry, with young adult Hispanic women vulnerable to worry about recurrence.

IMPLICATIONS FOR CANCER SURVIVORS

Hispanic women with thyroid cancer may benefit from targeted psychosocial support during survivorship, with interventions informed by patient and cancer characteristics.

Isobutanol tolerance and production of Saccharomyces cerevisiae can be improved by engineering its TATA-binding protein Spt15

Low isobutanol tolerance of Saccharomyces cerevisiae limits its application in isobutanol fermentation. Here, we used global transcription machinery engineering to screen mutants with higher isobutanol tolerance and elevated isobutanol titres. TATA-binding protein Spt15 was used as the target of global transcription machinery engineering for improvement of such complex phenotypes. A random mutagenesis library of S. cerevisiae TATA-binding protein Spt15 was constructed and subjected to screening under isobutanol stress. A mutant strain (denoted as spt15-3) with improved isobutanol tolerance was identified. There were three mutations of Spt15 in strain spt15-3, including deletion of A at position -132 nt upstream of initiation codon, insertion of G at position -65 nt upstream of initiation codon and a synonymous mutation at position 315 nt (T → C) downstream of initiation codon. We then metabolically engineered isobutanol synthesis in strains harbouring plasmids YCplac22 containing these Spt15 mutations. Delta integration was used to overexpress ILV3 gene, and 2μ plasmids carrying PGK1p-ILV2 and PGK1p-ARO10 were used to overexpress ILV2 and ARO10 genes. After 24-h micro-aerobic fermentation, Engi-3 produced 0·556 g l^-1 isobutanol, which was 404% and 25·3% greater than isobutanol produced by control Engi-1 and engineered Engi-2, respectively. After 28 h, Engi-4 produced 0·459 g l^-1 isobutanol, which was 315% and 3·2% greater than isobutanol produced Engi-1 and Engi-2, respectively. RNA-Seq-based transcriptome analysis shows that mutations of Spt15 in strain spt15-3 increased the expression of SPT15. Meanwhile, compared with strain Engi-3, the spt15-3 mutation downregulated the expression of genes involved in the TCA cycle and glyoxylic acid cycle, but increased the expression of genes related to cell stability. This work demonstrates that isobutanol tolerance and production of S. cerevisiae can be improved by engineering its TATA-binding protein Spt15. This study clarified the molecular mechanisms regulating isobutanol production and tolerance in S. cerevisiae.

A Review of Mechano-Biochemical Models for Testing Composite Restorations

Due to the severe mechano-biochemical conditions in the oral cavity, many dental restorations will degrade and eventually fail. For teeth restored with resin composite, the major modes of failure are secondary caries and fracture of the tooth or restoration. While clinical studies can answer some of the more practical questions, such as the rate of failure, fundamental understanding on the failure mechanism can be obtained from laboratory studies using simplified models more effectively. Reviewed in this article are the 4 main types of models used to study the degradation of resin-composite restorations, namely, animal, human in vivo or in situ, in vitro biofilm, and in vitro chemical models. The characteristics, advantages, and disadvantages of these models are discussed and compared. The tooth-restoration interface is widely considered the weakest link in a resin composite restoration. To account for the different types of degradation that can occur (i.e., demineralization, resin hydrolysis, and collagen degradation), enzymes such as esterase and collagenase found in the oral environment are used, in addition to acids, to form biochemical models to test resin-composite restorations in conjunction with mechanical loading. Furthermore, laboratory tests are usually performed in an accelerated manner to save time. It is argued that, for an accelerated multicomponent model to be representative and predictive in terms of both the mode and the speed of degradation, the individual components must be synchronized in their rates of action and be calibrated with clinical data. The process of calibrating the in vitro models against clinical data is briefly described. To achieve representative and predictive in vitro models, more comparative studies of in vivo and in vitro models are required to calibrate the laboratory studies.

P–138 When is low quality really low? Should we transfer low-grade blastocysts?

Study question

What is the live birth rate after single, low-grade blastocyst (LGB) transfer?

Summary answer

The live birth rate for LGBs is 28%, ranging between 15–31% for the different inner cell mass (ICM) and trophectoderm (TE) subgroups of LGBs.

What is known already

Live birth rates following LGB transfer are varied and have been reported to be in the range of 5–39%. However, these estimates are inaccurate as studies investigating live birth rates following LGB transfer are inherently limited by sample size (n = 10–440 for LGB transfers) due to LGBs being ranked last for transfer. Further, these studies are heterogenous with varied LGB definitions and design. Collating LGB live birth data from multiple clinics is warranted to obtain sufficient numbers of LGB transfers to establish reliable live birth rates, and to allow for delineation of different LGB subgroups, including blastocyst age and female age.

Study design, size, duration

We performed a multicentre, multinational retrospective cohort study in 9 IVF centres in China and New Zealand from 2012 to 2019. We studied the outcome of 6966 single blastocyst transfer cycles on days 5–7 (fresh and frozen) according to blastocyst grade, including 875 transfers from LGBs (&lt;3bb, this being the threshold typically applied to LGB studies). Blastocysts with expansion stage 1 or 2 (early blastocysts) were excluded.

Participants/materials, setting, methods

The main outcome measured was live birth rate. Blastocysts were grouped according to quality grade: good-grade blastocysts (GGBs; n = 3849, aa, ab and ba), moderate-grade blastocysts (MGBs; n = 2242, bb) and LGBs (n = 875, ac, ca, bc, cb and cc) and live birth rates compared using the Pearson Chi-squared test. A logistic regression analysis explored the relationship between blastocyst grade and live birth after adjustment for the confounders: clinic, female age, expansion stage, and blastocyst age.

Main results and the role of chance

The live birth rates for GGBs, MGBs and LGBs were 45%, 36% and 28% respectively (p &lt; 0.0001). Within the LGB group, the highest live birth rates were for grade c TE (30%) and the lowest were for grade c ICM (19%). The lowest combined grade (cc) maintained a 15% live birth rate (n = 7/48). After accounting for confounding factors, including female age and blastocyst characteristics, the odds of live birth were 2.33 (95% CI = 1.88–2.89) for GGBs compared to LGBs and 1.56 (95% CI = 1.28–1.92) for MGBs compared to LGBs following fresh and frozen blastocyst transfers (p &lt; 0.0001, odds ratios confirmed in exclusively frozen blastocyst transfer cycles). When stratified by individual ICM and TE grade, the odds of live birth according to ICM grade were 1.31 (a versus b; 95% CI = 1.15–1.48), 2.82 (a versus c; 95% CI = 1.91–4.18) and 2.16 (b versus c; 95% CI = 1.48–3.16; all p &lt; 0.0001). The odds of live birth according to TE grade were 1.33 (a versus b; 95% CI = 1.17–1.50, p &lt; 0.0001), 1.85 (a versus c; 95% CI = 1.45–2.34, p &lt; 0.0001) and 1.39 (b versus c; 95% CI = 1.12–1.73, p = 0.0024).

Limitations, reasons for caution

Despite the large multicentre design of the study, analyses of transfers occurring within the smallest subsets of the LGB group were limited by sample size. The study was not randomised and had a retrospective character.

Wider implications of the findings: LGBs maintain satisfactory live birth rates (averaging 28%) in the general IVF population. Even those in the lowest grading tier maintain modest live birth rates (15%; cc). It is recommended that LGBs not be universally discarded, and instead considered for subsequent frozen embryo transfer to maximize cumulative live birth rates.

Solution-focused brief therapy for adolescent and young adult cancer patients in China: a pilot randomized controlled trial

OBJECTIVE

This pilot clinical trial investigated solution-focused brief therapy (SFBT) for psychological distress among adolescent and young adult (AYA) patients with cancer in China.

METHODS

Fifty Chinese AYA patients diagnosed with cancer were randomized into the treatment group (SFBT) and control group (active control). Psychological distress was measured by the brief symptom inventory and hope was measured by the Herth-Hope-Index. Treatment effects were analyzed using analysis-of-covariance and between-group small-sample-size corrected Hedges' g.

RESULTS

The results indicated that SFBT resulted in a significant reduction in the psychological distress and improvement in hope of AYA patients with cancer. Analyses of the 4-week posttreatment score suggest the short-term sustainability of SFBT for psychological distress among AYAs diagnosed with cancer.

CONCLUSIONS AND IMPLICATIONS

This study has demonstrated that SFBT's impact is statistically significant and clinically meaningful. The inclusion of positive emotions, i.e., hope, as part of the investigation also highlighted the significance of promoting positive emotions among AYA patients with cancer.
