T cells but not NK cells are associated with a favourable outcome for resected colorectal liver metastases

T cells, but not NK cells, are preferentially recruited to colorectal liver metastases. NK cells within colorectal metastases have an intrahepatic and potentially tolerogenic, rather than a peripheral, phenotype. Similar to primary tumours, the magnitude of the T cell infiltrate in colorectal metastases is positively associated with surviva

Electronic cigarette use (vaping) and patterns of tobacco cigarette smoking in pregnancy-evidence from a population-based maternity survey in England.

OBJECTIVES: Exposure to tobacco products during pregnancy presents a potential harm to both mother and baby. This study sought to estimate the prevalence of vaping during pregnancy and to explore the factors and outcomes associated with vaping in pregnancy. SETTING: England. PARTICIPANTS: Women who gave birth between 15th and 28th October 2017. METHODS: A cross-sectional population-based postal survey of maternal and infant health, the National Maternity Survey (NMS) 2018. The prevalence of vaping and patterns of cigarette smoking were estimated, and regression analysis was used to explore associations between maternal characteristics and vaping, and between vaping and birth outcomes. OUTCOME MEASURES: Unweighted and weighted prevalence of vaping with 95% confidence intervals, and unadjusted and adjusted relative risks or difference in means for the association of participant characteristics and secondary outcomes with vaping. Secondary outcome measures were: preterm birth, gestational age at birth, birthweight, and initiation and duration of breastfeeding. RESULTS: A total of 4,509 women responded to the survey. The prevalence of vaping in pregnancy was 2.8% (95%CI 2.4% to 3.4%). This varied according to the pattern of cigarette smoking in pregnancy: 0.3% in never-smokers; 3.3% in ex-smokers; 7.7% in pregnancy-inspired quitters; 9.5% in temporary quitters; and 17.7% in persistent smokers. Younger women, unmarried women, women with fewer years of formal education, women living with a smoker, and persistent smokers were more likely to vape, although after adjusting for pattern of cigarette smoking and maternal characteristics, persistent smoking was the only risk factor. We did not find any association between vaping and preterm birth, birthweight, or breastfeeding. CONCLUSIONS: The prevalence of vaping during pregnancy in the NMS 2018 was low overall but much higher in smokers. Smoking was the factor most strongly associated with vaping. Co-occurrence of vaping with persistent smoking has the potential to increase the harms of tobacco exposure in pregnant women and their infants

Cut-off points for anthropometric indices of adiposity: differential classification in a large population of young women

Anthropometric indices of adiposity include BMI, waist circumference and waist:height ratio. In the recruitment phase of a prospective cohort study carried out between 1998 and 2002 we studied a population sample of 11 786 white Caucasian non-pregnant women in Southampton, UK aged 20-34 years, and explored the extent to which proposed cut-off points for the three indices identified the same or different women and how these indices related to adiposity. Height, weight and waist circumference were measured and fat mass was estimated from skinfold thicknesses; fat mass index was calculated as fat mass/height1.65. Of the subjects, 4869 (42 %) women were overweight (BMI >/= 25 kg/m2) and 1849 (16 %) were obese (BMI >/= 30 kg/m2). A total of 890 (8 %) subjects were not overweight but had a waist circumference >/= 80 cm and 748 (6 %) subjects were overweight but had a waist circumference /= 0.5. Of the variation in fat mass index, 85 % was explained by BMI, 76 % by waist circumference and 75 % by waist:height ratio. Our findings demonstrate that many women are differentially classified depending on which index of adiposity is used. As each index captures different aspects of size in terms of adiposity, there is the need to determine how the three indices relate to function and how they can be of use in defining risk of ill health in women

Impact of sampling and data collection methods on maternity survey response: a randomised controlled trial of paper and push-to-web surveys and a concurrent social media survey

Abstract Background Novel survey methods are needed to tackle declining response rates. The 2020 National Maternity Survey included a randomised controlled trial (RCT) and social media survey to compare different combinations of sampling and data collection methods with respect to: response rate, respondent representativeness, prevalence estimates of maternity indicators and cost. Methods A two-armed parallel RCT and concurrent social media survey were conducted. Women in the RCT were sampled from ONS birth registrations and randomised to either a paper or push-to-web survey. Women in the social media survey self-selected through online adverts. The primary outcome was response rate in the paper and push-to-web surveys. In all surveys, respondent representativeness was assessed by comparing distributions of sociodemographic characteristics in respondents with those of the target population. External validity of prevalence estimates of maternity indicators was assessed by comparing weighted survey estimates with estimates from national routine data. Cost was also compared across surveys. Results The response rate was higher in the paper survey (n = 2,446) compared to the push-to-web survey (n = 2,165)(30.6% versus 27.1%, difference = 3.5%, 95%CI = 2.1–4.9, p < 0.0001). Compared to the target population, respondents in all surveys were less likely to be aged < 25 years, of Black or Minority ethnicity, born outside the UK, living in disadvantaged areas, living without a partner and primiparous. Women in the social media survey (n = 1,316) were less representative of the target population compared to women in the paper and push-to-web surveys. For some maternity indicators, weighted survey estimates were close to estimates from routine data, for other indicators there were discrepancies; no survey demonstrated consistently higher external validity than the other two surveys. Compared to the paper survey, the cost saving per respondent was £5.45 for the push-to-web survey and £22.42 for the social media survey. Conclusions Push-to-web surveys may cost less than paper surveys but do not necessarily result in higher response rates. Social media surveys cost significantly less than paper and push-to-web surveys, but sample size may be limited by eligibility criteria and recruitment window and respondents may be less representative of the target population. However, reduced representativeness does not necessarily introduce more bias in weighted survey estimates

A Comparison of Three Measures to Identify Postnatal Anxiety: Analysis of the 2020 National Maternity Survey in England

Perinatal anxiety affects an estimated 15% of women globally and is associated with poor maternal and infant outcomes. Identifying women with anxiety is essential to prevent these adverse associations, but there are a number of challenges around measurement. We used data from England’s 2020 National Maternity Survey to compare the prevalence of anxiety symptoms at six months postpartum using three different measures: the two-item Generalised Anxiety Disorders Scale (GAD-2), the anxiety subscales of the Edinburgh Postnatal Depression Scale (EPDS-3A) and a direct question. The concordance between each pair of measures was calculated using two-by-two tables. Survey weights were applied to increase the representativeness of the sample and reduce the risk of non-response bias. The prevalence of postnatal anxiety among a total of 4611 women was 15.0% on the GAD-2, 28.8% on the EPDS-3A and 17.1% on the direct question. Concordance between measures ranged between 78.6% (95% CI 77.4–79.8; Kappa 0.40) and 85.2% (95% CI 84.1–86.2; Kappa 0.44). Antenatal anxiety was the strongest predictor of postnatal anxiety across all three measures. Women of Black, Asian or other minority ethnicity were less likely to report self-identified anxiety compared with women of White ethnicity (adjusted odds ratio 0.44; 95% CI 0.30–0.64). Despite some overlap, different anxiety measures identify different groups of women. Certain population characteristics such as women’s ethnicity may determine which type of measure is most likely to identify women experiencing anxiety

The relationship between perineal trauma and postpartum psychological outcomes: a secondary analysis of a population-based survey

Abstract Background Perineal trauma, involving either naturally occurring tears or episiotomy, is common during childbirth but little is known about its psychological impact. This study aimed to determine the associations between childbirth related perineal trauma and psychological outcomes reported by women three months after giving birth and to explore factors that could mediate relationships between perineal trauma and maternal psychological outcomes. Methods This study was a secondary analysis of data from a cross-sectional population-based survey of maternal and infant health. A total of 4,578 women responded to the survey, of which 3,307 had a vaginal birth and were eligible for inclusion into the analysis. Symptoms of depression, anxiety, and post-traumatic stress (PTS) symptoms were assessed using validated self- report measures. Physical symptoms were derived from a checklist and combined to produce a composite physical symptoms score. Regression models were fitted to explore the associations. Results Nearly three quarters of women experienced some degree of perineal trauma. Women who experienced perineal trauma reported having more postnatal physical symptoms (adjusted proportional odds ratio 1.47, 95%CI 1.38 to 1.57, p-value < 0.001), were more likely to report PTS symptoms (adjusted OR 1.19, 95%CI 1.04 to 1.36, p-value 0.010), and there was strong evidence that each unit increase in the physical symptoms score was associated with between 38 and 90% increased adjusted odds of adverse psychological symptoms. There was no evidence of association between perineal trauma and satisfaction with postnatal care, although there was strong evidence that satisfaction with labour and birth was associated with 16% reduced adjusted odds of depression and 30% reduced adjusted odds of PTS symptoms. Conclusions Women who experienced perineal trauma were more likely to experience physical symptoms, and the more physical symptoms a woman experienced the more likely she was to report having postnatal depression, anxiety and PTS symptoms. There was some evidence of a direct association between perineal trauma and PTS symptoms but no evidence of a direct association between perineal trauma and depression or anxiety. Assessment and management of physical symptoms in the postnatal period may play an important role in reducing both physical and psychological postnatal morbidity

Identifying postnatal anxiety: comparison of self-identified and self-reported anxiety using the Edinburgh Postnatal Depression Scale

BACKGROUND: Identifying women with perinatal anxiety is important in order to provide timely support and prevent adverse outcomes. Self-report instruments are commonly used in maternity settings. An alternative is to ask women directly whether they self-identify as having anxiety. We examine the agreement between self-reported and self-identified anxiety at 3 months postpartum and compare the characteristics of women with self-reported and self-identified anxiety. METHODS: A secondary analysis of national maternity surveys conducted in 2014 in England and Northern Ireland was conducted. Self-reported anxiety was assessed using the Edinburgh Postnatal Depression Scale anxiety subscale (EPDS-3A). Agreement between self-reported and self-identified anxiety was measured using Cohen’s kappa. Logistic regression was used to identify characteristics of women in each group. RESULTS: In our sample of 6752 women, 14.2% had self-reported anxiety, 5.9% had self-identified anxiety and 3.5% were positive on both measures. Among those with self-identified anxiety, 58.1% also had self-reported anxiety. Of those with self-reported anxiety, 24.4% also had self-identified anxiety. Statistical agreement between the two measures was minimal with Cohen’s kappa 0.283 at an EPDS-3A threshold of ≥6. Among both self-identified and self-reported anxiety groups, psychological factors were the strongest associated factors. Women with self-reported anxiety had higher odds of being from Northern Ireland (OR 1.81); having a mixed or unhappy reaction to the pregnancy (OR 1.65); living without a partner (aOR 1.37); and antenatal depression (aOR 1.32). Women with self-identified anxiety had higher odds of physical problems (OR 1.84); and being of Black or minority ethnicity (OR 0.39). CONCLUSIONS: Asking postnatal women directly whether they self-identify as having anxiety identifies a different group of women from those who score highly on self-report measures. Women with self-identified anxiety may benefit from further follow-up and support

Validated screening tools to identify common mental disorders in perinatal and postpartum women in India: a systematic review and meta-analysis

Background Perinatal common mental disorders are associated with significant adverse outcomes for women and their families, particularly in low- and middle-income settings. Early detection through screening with locally-validated tools can improve outcomes. Methods We searched MEDLINE, Embase, PsycINFO, Global Health, Cochrane Library, Web of Science and Google Scholar for articles on the validation of screening tools for common mental disorders in perinatal women in India, with no language or date restrictions. Quality was assessed using the QUADAS-2 tool. We used bivariate and hierarchical summary receiver operating characteristic models to calculate pooled summary estimates of sensitivity and specificity. Heterogeneity was assessed by visualising the distance of individual studies from the summary curve. Results Seven studies involving 1003 women were analysed. All studies assessed the validity of the Edinburgh Postnatal Depression Scale (EPDS) in identifying perinatal depression. No validation studies of any other screening tools were identified. Using a common threshold of ≥13 the EPDS had a pooled sensitivity and specificity of 88·9% (95%CI 77·4–94·9) and 93·4 (95%CI 81·5–97·8), respectively. Using optimal thresholds (range ≥ 9 to ≥13) the EPDS had a pooled sensitivity and specificity of 94·4% (95%CI 81·7–98·4) and 90·8 (95%CI 83·7–95·0), respectively. Conclusion The EPDS is psychometrically valid in diverse Indian settings and its use in routine maternity care could improve detection of perinatal depression. Further research is required to validate screening tools for other perinatal common mental disorders in India

Dance for people with chronic breathlessness: a transdisciplinary approach to intervention development

Objectives: A transdisciplinary research approach was used to develop a holistic understanding of the physical and psychosocial benefits of dance as an intervention for people living with chronic breathlessness. Methods: The dance programme was developed in collaboration with British Lung Foundation Breathe Easy members in NE England (Darlington) and London (Haringey). Members of the Darlington group were invited to participate in the programme. An exercise instructor, trained and mentored by a dance facilitator delivered 60–90 min dance classes for 10 consecutive weeks. Exercise capacity, mobility, quadriceps strength, health status, mood and interoceptive awareness were assessed at baseline and after the 10-week programme. Second-to-second heart rate (HR) monitoring was conducted during one of the classes. Results: Ten individuals were enrolled (n=8 women). Mean (SD) age was 70 (24); Body Mass Index 29.7 (8.1) kg/m2; one participant used oxygen and one a walking aid. Seven completed the dance programme. Improvements in all outcome measures were detected, with the exception of the Multidimensional Assessment of Interoceptive Awareness, which individuals found hard to comprehend. Eight participants wore HR monitors during one dance class and spent on average 43.5 (21.8) min with HR corresponding to at least moderate intensity physical activity (≥64% HRmax). People found the dance classes enjoyable and those with relevant past experiences who are optimistic, committed to staying well and playful readily adopted the programme. Conclusion: A dance programme bringing both physical and psychosocial benefits for people with chronic breathlessness is acceptable when coproduced and evaluated through a transdisciplinary approach
