IntroductionSouth Asians are more likely to develop gestational diabetes mellitus (GDM) than white Europeans. Diet and lifestyle modifications may prevent GDM and reduce undesirable outcomes in both the mother and offspring. Our study seeks to evaluate the effectiveness and participant acceptability of a culturally tailored, personalised nutrition intervention on the glucose area under the curve (AUC) after a 2-hour 75 g oral glucose tolerance test (OGTT) in pregnant women of South Asian ancestry with GDM risk factors.Methods and analysisA total of 190 South Asian pregnant women with at least 2 of the following GDM risk factors—prepregnancy body mass index>23, age>29, poor-quality diet, family history of type 2 diabetes in a first-degree relative or GDM in a previous pregnancy will be enrolled during gestational weeks 12–18, and randomly assigned in a 1:1 ratio to: (1) usual care, plus weekly text messages to encourage walking and paper handouts or (2) a personalised nutrition plan developed and delivered by a culturally congruent dietitian and health coach; and FitBit to track steps. The intervention lasts 6–16 weeks, depending on week of recruitment. The primary outcome is the glucose AUC from a three-sample 75 g OGTT 24–28 weeks’ gestation. The secondary outcome is GDM diagnosis, based on Born-in-Bradford criteria (fasting glucose>5.2 mmol/L or 2 hours post load>7.2 mmol/L).Ethics and disseminationThe study has been approved by the Hamilton Integrated Research Ethics Board (HiREB #10942). Findings will be disseminated among academics and policy-makers through scientific publications along with community-orientated strategies.Trial registration numberNCT03607799.

ObjectiveSkeletal muscle mass (SMM) is an important biomarker for prognosis and health in older patients with cancer. Limited information is available on the recovery course of SMM after oesophagectomy following neoadjuvant chemotherapy (NAC) in older patients. This study was performed to investigate the recovery course of SMM after oesophagectomy following NAC and the preoperative predictors of delayed recovery in older patients with locally advanced oesophageal cancer (LAEC).MethodsThis single-centre retrospective cohort study involved older (≥65 years) and non-older (<65 years) patients with LAEC who underwent oesophagectomy following NAC. The SMM index (SMI) was calculated using CT images. One-way analysis of variance and multivariate logistic regression analysis were performed.ResultsIn total, 110 older patients and 57 non-older patients were analysed. Loss of the SMI after NAC to 12 months postoperatively was significantly greater in older patients than in non-older patients (p<0.01). The significant preoperative predictor of delayed recovery of the SMI 12 months after surgery was loss of the SMI during NAC in older patients (per 1%: adjusted OR 1.249; 95% CI 1.131 to 1.403; p<0.001), but not in non-older patients (per 1%: OR 1.074; 95% CI 0.988 to 1.179; p=0.108).ConclusionsThere is an especially large unmet need for preventing the long-term sequelae of SMM loss in older patients with LAEC after oesophagectomy following NAC. In older patients, loss of SMM during NAC is an especially useful biomarker for prescribing postoperative rehabilitation to prevent postoperative loss of SMM.
Understanding Long-Term Survival of Patients with Ovarian Cancer—The Tumor Microenvironment Comes to the Forefront
Authors: Kelliher Lucy , Lengyel Ernst 
Published: May 2023

High-grade serous ovarian cancer (HGSOC) is the deadliest subtype of ovarian cancer, and most patients do not survive more than 5 years after diagnosis. Yet, for reasons that are often elusive, approximately 15% of women with advanced-stage HGSOC will survive longer than 10 years. An understanding of the biological basis of long-term survival with HGSOC may elucidate novel prognostic factors and targets for treatment. Past analyses of the clinicopathologic features of these women and genetic profiles of their tumors have not revealed a unifying explanation for their increased longevity. In this issue of Cancer Research, Ferri-Borgogno and colleagues investigate the tumor microenvironment (TME) in samples from both long- and short-term survivors using spatial transcriptomics and single-cell RNA sequencing. They found that, in metastatic tumors, various populations of cancer-associated fibroblasts (CAF) in the TME play different roles in supporting the malignant phenotype of ovarian cancer cells. Higher density of CAFs, particularly αSMA+VIM+PDGFRβ+ CAFs, was associated with lower tumor immune infiltration and short-term survival. There was also marked expression of periostin and CD36 in spatially resolved CAFs, as well as a prevalence of the APOE-LRP5 ligand-receptor pair at the tumor-stromal interface in tissue from short-term survivors. These findings suggest that, in short-term survivors, CAFs are able to more effectively promote tumorigenicity, stemness, and chemoresistance in the nearby tumor.See related article by Ferri-Borgogno et al., p. 1503

Published: May 2023

Abstract

Background:
Lifetime ovulatory years (LOY) is estimated by the difference between ages at menopause and menarche subtracting time for events interrupting ovulation. We tested whether LOY influences sex hormone levels in postmenopausal women with at least one intact ovary not using hormones.

Methods:
Estradiol, estrone, estrone sulfate, total testosterone, dehydroepiandrostendione sulfate, prolactin, and sex hormone binding globulin were measured in 1,976 postmenopausal women from the Nurses’ Health Study. Associations of age, body mass index (BMI), smoking, alcohol use, and other factors on hormones were assessed by t tests and ANOVA. Linear regression was used to assess multivariable adjusted associations between LOY and hormones and trends in hormone levels per 5-year increases in LOY were estimated.

Results:
Women averaged 61.4 years old, 11.0 years since menopause, with BMI of 25.8 kg/m2. A total of 13.6% had irregular cycles, 17.5% hysterectomy, 6.4% unilateral oophorectomy, and 13.8% were current smokers. Variables associated with one or more hormone levels were included as covariates. Each 5-year increase in LOY was significantly associated with a 5.2% increase in testosterone in women with BMI &lt; 25 kg/m2 and a 7.4% increase in testosterone and 7.3% increase in estradiol in women with above-average BMI.

Conclusions:
This is the first study to show that greater LOY is associated with higher testosterone in postmenopausal women and higher estradiol in those with elevated BMI, suggesting accumulation of functioning stromal and thecal cells from repeated ovulations and peripheral conversion of testosterone.

Impact:
A possible explanation for why greater LOY increases risk for breast, endometrial, and ovarian cancer is offered.

AbstractPoor infiltration of T lymphocytes has been regarded as a crucial mechanism of tumor immune escape. Here, we demonstrate a protective role of KRT17 in colorectal cancer, where KRT17 reversed the tumor immunosuppressive microenvironment by increasing T-lymphocyte infiltration. High-throughput RNA sequencing suggested that KRT17 was significantly upregulated in deficient mismatch repair (dMMR) tumors compared with proficient mismatch repair (pMMR) tumors. In a colorectal cancer cohort of 446 cases, KRT17 expression positively correlated with better clinical outcomes. Krt17 overexpression decreased xenograft tumor growth in immune-competent mice. T-cell depletion in a murine model showed that the presence of T lymphocytes was necessary for Krt17-mediated disruption of tumorigenesis. Mass spectrometry and coimmunoprecipitation assays suggested KRT17 caused YTHDF2 degradation through the ubiquitin-proteasome system. Through high-throughput RNA immunoprecipitation sequencing, we found that CXCL10 was the target gene of the N6-methyladenosine (m6A) “reader” YTHDF2. KRT17 synergized with anti–PD-1 for better tumor control in an immunotherapy-resistant murine model. In a cohort of patients with colorectal cancer receiving pembrolizumab, high KRT17 expression was found within the tumors of responders. Collectively, we elucidated a critical role of KRT17 in colorectal cancer to prevent immune escape. These findings present new insights into potential therapeutic strategies and effective markers of immunotherapy reactivity against pMMR tumors.

Published: May 2023

Background:
After myocardial infarction, the infarct border zone (BZ) is the dominant source of life-threatening arrhythmias, where fibrosis and abnormal repolarization create a substrate for reentry. We examined whether repolarization abnormalities are heterogeneous within the BZ in vivo and could be related to heterogeneous cardiomyocyte remodeling.

Methods:
Myocardial infarction was induced in domestic pigs by 120-minute ischemia followed by reperfusion. After 1 month, remodeling was assessed by magnetic resonance imaging, and electroanatomical mapping was performed to determine the spatial distribution of activation-recovery intervals. Cardiomyocytes were isolated and tissue samples collected from the BZ and remote regions. Optical recording allowed assessment of action potential duration (di-8-ANEPPS, stimulation at 1 Hz, 37 °C) of large cardiomyocyte populations while gene expression in cardiomyocytes was determined by single nuclear RNA sequencing.

Results:

In vivo, activation-recovery intervals in the BZ tended to be longer than in remote with increased spatial heterogeneity evidenced by a greater local SD (3.5±1.3 ms versus remote: 2.0±0.5 ms,
P
=0.036, n
pigs
=5). Increased activation-recovery interval heterogeneity correlated with enhanced arrhythmia susceptibility. Cellular population studies (n
cells
=635–862 cells per region) demonstrated greater heterogeneity of action potential duration in the BZ (SD, 105.9±17.0 ms versus remote: 73.9±8.6 ms;
P
=0.001; n
pigs
=6), which correlated with heterogeneity of activation-recovery interval in vivo. Cell-cell gene expression heterogeneity in the BZ was evidenced by increased Euclidean distances between nuclei of the BZ (12.1 [9.2–15.0] versus 10.6 [7.5–11.6] in remote;
P
<0.0001). Differentially expressed genes characterizing BZ cardiomyocyte remodeling included hypertrophy-related and ion channel–related genes with high cell-cell variability of expression. These gene expression changes were driven by stress-responsive TFs (transcription factors). In addition, heterogeneity of left ventricular wall thickness was greater in the BZ than in remote.

Conclusions:
Heterogeneous cardiomyocyte remodeling in the BZ is driven by uniquely altered gene expression, related to heterogeneity in the local microenvironment, and translates to heterogeneous repolarization and arrhythmia vulnerability in vivo.

Published: May 2023

Abstract
Despite the global norm favoring women’s participation in peace negotiations, women continue to face constraints in accessing, influencing, and benefitting from peace settlements. This special issue of International Negotiation lays the groundwork for a future research agenda, calling for attention to gender-based analysis; mixed-method research designs, comparative case studies, and attention to “negative” cases; more examination of the relationship between gender-inclusivity at peace talks and the subsequent conditions for women; and policy recommendations for international actors. This introduction to the issue provides a review of the literature on women and peace negotiations, offers an overview of the issue’s six articles, and proposes a future research agenda.
Task-Relevant Smartphone Messages Within Work Zones: A Driving Simulation Study
Authors: Craig Curtis M. , Tian Disi , Morris Nichole L. 
Published: May 2023

Objective This study explored the impact of in-vehicle messages relative to roadside messages to alert drivers to events within a simulated work zone, in order to determine if these messages can improve driving performance within the work zone. Background Safety risks in work zones are usually mitigated by design standards and clear signage to communicate work zone information to drivers. Due to distraction and other driving task demands, these signs are not always noticed by motorists, nor are they always followed when they are noticed. Method The driving simulation tested drivers in two different types of work zones, shoulder work, and lane closure. Participants drove through these work zones three times, each with different messaging interfaces to communicate hazardous events to the driver. The interfaces included a roadside, portable changeable message sign, a smartphone presenting only auditory messages, and a smartphone presenting audio-visual messages. Results There was significantly better driving performance on key metrics including lane deviation for the in-vehicle message conditions relative to the roadside signs. Furthermore, drivers directed visual attention toward the roadway for the in-vehicle message conditions relative to the roadside sign condition. Conclusion The results indicate that in-vehicle messaging could provide benefits to primary task performance in driving if the message content is appropriately designed. Application The findings provide support for a design framework to support in-vehicle communication to drivers approaching work zones and other environments to safely alert them to hazards.

Published: May 2023

Background: Recovery in psychosis is a multidimensional construct. The numbers of studies specially focusing on the recovery aspects in patients with first episode psychosis (FEP) are limited, with no study from India. Further, no study has looked specifically into the variables that affect recovery process in patients with FEP and little is known about factors which influence recovery in patients with FEP. Aim: To evaluate psychological recovery and its correlates in patients with FEP, currently in clinical remission. Methodology: One hundred three patients of FEP in clinical remission were assessed on Recovery Assessment Scale (RAS), Positive and Negative Syndrome Scale for Schizophrenia, Calgary Depression Rating Scale for Schizophrenia, Negative Symptom Assessment 16, Rosenberg Self-esteem Scale, Social and Occupational Functioning Assessment Scale, the Alcohol, Smoking and Substance Involvement Screening Test, Beck Cognitive Insight Scale, Internalized Stigma of Mental Illness Scale, the Everyday discrimination Scale, Subjective Scale to Investigate Cognition in Schizophrenia and social cognitive deficits in theory of mind was evaluated on the Social Cognition Rating Tools in Indian Setting-Theory of Mind. The needs of the participants were assessed on the Camberwell Assessment of Needs – Research version and Supplemental Assessment of Needs. Coping, social support, medication adherence were also assessed by standardized scales. Results: The mean weighted score was highest for goal and success orientation subscale followed by seeking and relying on social support, personal confidence and hope, overcome the illness and awareness and control over the illness as assessed by 41 items of the RAS. The main factors identified to affect psychological recovery in patients with FEP were duration of untreated psychosis, greater psychopathology, lower self-esteem, total unmet need, feeling of discrimination and stigmatization. Conclusion: The present study suggests that treatment of FEP should be started at the earliest and issues such as residual psychopathology, lower self-esteem, total unmet need, feeling of discrimination and stigma during the remission phase should be addressed by psychosocial interventions to promote psychological recovery in patients with first episode psychosis.
Health professionals’ experiences of rapport during telehealth encounters in community palliative care: An interpretive description study
Authors: English Wendy , Robinson Jackie , Gott Merryn 
Published: May 2023

Background: Despite the reported importance of rapport, there are knowledge gaps in the ways rapport is developed and experienced by health professionals during telehealth calls in palliative care. Aim: To gain an understanding about developing rapport during telehealth calls by exploring the experiences of health professionals in community palliative care. Design: A qualitative Interpretive Description study was conducted with semi-structured interviews and focus groups between November 2020 and May 2021. Data was audio recorded, transcribed, and analysed using Reflexive thematic analysis. A COREQ checklist was completed. Setting/Participants: Thirty-one palliative care professionals who had participated in telehealth calls were recruited from four hospice locations in Aotearoa, New Zealand. Results: There were two themes identified: (1) ‘Getting on together’, which included how rapport shows up in telehealth, with examples of calls with rapport and without rapport, and (2) ‘Rapport is a soft skill’, which identified health professionals using body language and listening in specific ways in telehealth, while being aware of the privacy of calls, and lack of training concerns. Conclusion: Based on health professionals experiences of rapport it was determined that rapport is vitally important in telehealth calls, as it is in-person interactions. Rapport is a soft skill that can potentially be learned, practiced and mastery developed, although rapport in each interaction is not guaranteed. Patient and family experiences of rapport in the palliative telehealth area warrants further research and there is some urgency for health professional training in telehealth interpersonal skills.
‘You have a little human being kicking inside you and an unbearable pain of knowing there will be a void at the end’: A meta-ethnography exploring the experience of parents whose baby is diagnosed antenatally with a life limiting or life-threatening condition
Authors: Tatterton Michael J , Fisher Megan J 
Published: May 2023

Background: Parents of babies diagnosed with life limiting conditions in the perinatal period face numerous challenges. Considerations include the remainder of the pregnancy, delivery of the baby and decisions around care in the neonatal period. Aim: To increase understanding of how parents experience the diagnosis of a life-limiting or life-threatening condition, during pregnancy and following the birth of their baby, by answering the question: ‘what is known about the perinatal experiences of parents of babies with a life-limiting or life-threatening diagnosis?’ Design: A meta-ethnography was conducted to synthesise findings from existing qualitative evidence. Data sources: British Nursing Database, CINAHL, Medline, PsycINFO and Embase databases were searched in January 2023. Findings: Relationships between parents and their families and friends, and with professionals influence the needs and experiences of parents, which oscillate between positive and negative experiences, throughout parents’ perinatal palliative care journey. Parents highlighted the need for control and a sense of normality relating to their parenting experience. Validation was central to the experience of parents at all stages of parenthood. Relationships between the parent and the baby were unwavering, underpinned with unconditional love. Conclusion: Professionals, family members and friendship groups influence the experience, validating parents and their baby’s identity and supporting parents in having a sense of control and normality by demonstrating empathy, and providing time and clear communication.
‘It is easier to not allow them to see your disability straight away, to see you as a person’: An Interpretative Phenomenological Analysis of video gaming from the perspectives of men with Duchenne Muscular Dystrophy
Authors: Peat George , Rodriguez Alison , Smith Joanna 
Published: May 2023

Background: Young men with Duchenne Muscular Dystrophy benefit from palliative care that supports their psychosocial needs. Acknowledging the sub-cultures they engage with can support their wellbeing. Anecdotal reports suggest video gaming is a sub-culture engaged with by young men with Duchenne Muscular Dystrophy. Aim: To explore the lived experience of video gaming from the perspective of young men with Duchenne Muscular Dystrophy. Design: Interpretative Phenomenological Analysis approach involving in-depth interviews using a topic guide that focused on social media broadly, with reference to video gaming. Sequential interviewing was undertaken to support participation regarding fatigue and tiredness, symptoms of Duchenne Muscular Dystrophy. Setting/participants: Participants were purposefully recruited from a hospice in the North of England. Twitter was used to support recruitment. Eight young men with Duchenne Muscular Dystrophy were recruited to the study. Results: Five themes were developed; ‘gamer as a shared and accepted identity’, ‘an existential and bodily escapism’, ‘introspection through video gaming’, ‘video gaming as a release’ and ‘when life gives you few choices-video game’. Motivations for engagement with video gaming are diverse and reflective of the situated perspectives of young men with Duchenne Muscular Dystrophy. Conclusions: An awareness of the popular sub-cultures that young men with Duchenne Muscular Dystrophy engage with is key to building a therapeutic alliance, establishing rapport and recognising personhood in interactions between professionals and persons in palliative care settings. This study highlights the value of video gaming, offering professionals valuable insight into its placement in the daily lives of young men with Duchenne Muscular Dystrophy.
