- Abstract
Background\ud About a third of women receiving pethidine for labour pain subsequently require an epidural, which provides effective pain relief but increases the risk of instrumental vaginal delivery. Remifentanil patient-controlled analgesia (PCA) in labour is an alternative to pethidine, but is not widely used. We aimed to evaluate epidural analgesia progression among women using remifentanil PCA compared with pethidine.\ud \ud Methods\ud We did an open-label, multicentre, randomised controlled trial in 14 UK maternity units. We included women aged 16 years or older, beyond 37 weeks' gestation, in labour with a singleton cephalic presentation, and who requested opioid pain relief. We randomly assigned eligible participants (1:1) to either the intravenous remifentanil PCA group (40 μg bolus on demand with a 2 min lockout) or the intramuscular pethidine group (100 mg every 4 h, up to 400 mg in 24 h), using a web-based or telephone randomisation service with a minimisation algorithm for parity, maternal age, ethnicity, and mode of labour onset. Because of the differences in routes of drug administration, study participants and health-care providers were not masked to the group allocation. The primary outcome was the proportion of women who received epidural analgesia after enrolment for pain relief in labour. Primary analyses were unadjusted and analysed by the intention-to-treat principle. This study is registered with the ISRCTN registry, number ISRCTN29654603.\ud \ud Findings\ud Between May 13, 2014, and Sept 2, 2016, 201 women were randomly assigned to the remifentanil PCA group and 200 to the pethidine group. One participant in the pethidine group withdrew consent, leaving 199 for analyses. The proportions of epidural conversion were 19% (39 of 201) in the remifentanil PCA group and 41% (81 of 199) in the pethidine group (risk ratio 0·48, 95% CI 0·34–0·66; p

- Abstract
(N Engl J Med. 2023;389:11–21)Postpartum hemorrhage (PPH) remains the leading cause of maternal death worldwide despite published recommendations from the World Health Organization (WHO) on prevention and treatment. There are challenges in implementing the PPH recommendations. Delay in detection as well as delay in treatment of PPH are 2 reasons the maternal death rate is high. One reason for the delay in detection is due to the ongoing use of visual estimation of blood loss, which often inaccurately underestimates the amount of lost blood. More aggressive interventions for PPH may be delayed until earlier approaches have failed in stopping the blood loss. In some cases, no effective treatment is administered at all. Finally, although the WHO has given these recommendations, not all hospitals and/or medical professionals are implementing them. This study sought to understand whether a treatment bundle referred to as E-MOTIVE could improve early detection and treatment of PPH in patients with a vaginal birth.

OBJECTIVES The primary objective of this study was to identify which patient demographic, patient health, and hospital characteristics were associated with in-hospital mortality. A secondary objective was to determine the relative influence of these characteristics on mortality. DESIGN AND SETTING Public-use data for 2005-2010 were used in this retrospective, cross-sectional analysis of discharges from nonfederal, general acute hospitals in California. A staged logistic regression approach was used to examine the relative influence of variables associated with in-hospital mortality. PATIENTS A total of 1,213,219 patient discharges for adults (aged ≥18 yrs) having International Classification of Diseases-9 diagnosis and procedure codes indicating severe sepsis. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS Patient demographics (age, gender, race, ethnicity, and payer category), patient health status (acute transfer, Charlson-Deyo comorbidity index, and organ failures), and hospital characteristics (ownership type, teaching status, bed size, annual patient days, acute discharges, emergency department visits, inpatient surgeries, severe sepsis as a percentage of all discharges, and year) were obtained from the California Office of Statewide Health Planning and Development. Overall, in-hospital mortality was 17.8%. There was a steady annual increase in the number of sepsis discharges, but a decrease in mortality throughout the study period. Mortality increased with age and was associated with white race, and Medicaid (Medi-Cal) and private insurance. Patient health status additionally explained inpatient mortality. Hospital volume measures were statistically significant in regression analysis, whereas static structural measures were not. There were modest associations between measures of annual treatment volume and likelihood of inpatient mortality, notably decreasing likelihood with more acute discharges and with greater severe sepsis volume. CONCLUSIONS Although patient demographics and health status are the most important predictors of in-hospital mortality of patients with severe sepsis, hospital characteristics do play a substantial role. Findings regarding hospital volume can be used to improve processes and improve patient outcomes.

We evaluated the changes in apolipoproteins, glycemic status, and body composition after 3 months using a culturally sensitive diabetes education program, En Balance, in diabetic Hispanics.Thirty-four (9 males, 25 females) Hispanic diabetics participated in the En Balance program over three months. Body composition was determined by dual energy X-ray absorptiometry (DXA), fasting plasma glucose (FPG), A1c, and apolipoproteins (Apo) measured after 3 months participation. Differences were analyzed using paired t testing and relationships between changes in Apo, A1c, total cholesterol, body mass index and body composition by Spearman correlations.Completion of En Balance resulted in a significant reduction in weight (80.31 +/- 1.97 kg vs 81.25 +/- 17.97 kg, P = .015), FPG (143.21 +/- 57.8 mg/dL vs 166.41 +/- 65.9 mg/dL P = .003), and A1c (7.08 +/- 1.6% vs 7.87 +/- 2.0%, P =.001). DXA demonstrated reduction in total fat (29.54 +/- 10.0 kg vs 30.24 +/- 11.80 kg, P =.001) and trunk fat (15.09 +/- 5.6 kg vs 16.87 +/- 5.4 kg, P = .001). High density lipoprotein significantly increased (48.85 +/- 11.4 vs 44.65 +/- 8.8, P = .002) and total serum cholesterol/high density lipoprotein ratio decreased (3.87 +/- .98 vs 4.35 +/- 1.0, P = .001). There were significant correlations at three months between changes in Apo A1 and A2 (r = .559, P.001), Apo E and total cholesterol (r = .746, P.001), between A1c and FPG (r = .563, P = .001) and BMI and body weight (r = .732, P.001).The En Balance program improved body composition, A1c, FPG, total cholesterol/HDL ratio and HDL. If these trends can be sustained, En Balance may serve as a unique educational paradigm for improving type 2 diabetes in Hispanics.

- Abstract
Vitamin D deficiency is more common in Blacks, yet Blacks have lower prevalence of bone fragility fractures or osteoporosis than Whites. Broadband ultrasound attenuation (BUA) has been used to explore the association between serum 25(OH)D levels and bone quality in White and non-white populations. We investigated serum 25(OH)D status with corresponding BUA measurements assessed cross sectionally in a cohort of 232 Blacks and 260 Whites, aged 30–95 years who were part of the calibration study of the large Adventist Health Study-2 (AHS-2). At the calibration clinics, calcaneal BUA was measured and blood drawn for serum 25(OH)D assessment. In multivariable analyses, BUA was negatively associated with age (β-coefficient = −0.38; p< 0.0001) and positively associated with body mass index (BMI) (p(trend)< 0.0001) and positively, but non-significantly, associated with serum 25(OH)D levels. Also, as expected, females had lower BUA (β-coefficient = −5.19; p< 0.05) and Blacks had higher BUA (β-coefficient = 4.26; p< 0.05). Gender and race modified the relationship of serum 25(OH)D on BUA with a positive association in males (p(trend)≤ 0.05), but no significant association in females after also controlling for menopausal status and hormone therapy. After also controlling for serum 25(OH)D levels, Black males had higher BUA than White men, but such differences were not found among the females. When stratifying on race, a positive association between serum 25(OH)D levels and BUA (p(trend)≤ 0.05) was found in Blacks, but not among Whites. Further studies are needed to understand how racial/ethnic differences in serum 25(OH)D levels influence bone health.

Background. Experiments in animals, international correlation comparisons, and case-control studies support an association between dietary fat intake and the incidence of breast cancer. Most cohort studies do not corroborate the association, but they have been criticized for involving small numbers of cases, homogeneous fat intake, and measurement errors in estimates of fat intake. Methods. We identified seven prospective studies in four countries that met specific criteria and analyzed the primary data in a standardized manner. Pooled estimates of the relation of fat intake to the risk of breast cancer were calculated, and data from study-specific validation studies were used to adjust the results for measurement error. Results. Information about 4980 cases from studies including 337,819 women was available. When women in the highest quintile of energy-adjusted total fat intake were compared with women in the lowest quintile, the multivariate pooled relative risk of breast cancer was 1.05 (95 percent confidence interval, 0.94 to 1.16). Relative risks for saturated, monounsaturated, and polyunsaturated fat and for cholesterol, considered individually, were also close to unity. There was little overall association between the percentage of energy intake from fat and the risk of breast cancer, even among women whose energy intake from fat was less than 20 percent. Correcting for error in the measurement of nutrient intake did not materially alter these findings. Conclusions. We found no evidence of a positive association between total dietary fat intake and the risk of breast cancer. There was no reduction in risk even among women whose energy intake from tat was less than 20 percent of total energy intake. In the context of the Western lifestyle, lowering the total intake of fat in midlife is unlikely to reduce the risk of breast cancer substantially. Chemicals/CAS: Dietary Fats

- Abstract
The association between anthropometric indices and the risk of breast cancer was analyzed using pooled data from seven prospective cohort studies. Together, these cohorts comprise 337,819 women and 4,385 incident invasive breast cancer cases. in multivariate analyses controlling for reproductive, dietary, and other risk factors, the pooled relative risk (RR) of breast cancer per height increment of 5 cm was 1.02 (95% confidence interval (CI): 0.96, 1.10) in premenopausal women and 1.07 (95% CI: 1.03, 1.12) in postmenopausal women. Body mass index (BMI) showed significant inverse and positive associations with breast cancer among pre- and postmenopausal women, respectively; these associations were nonlinear. Compared with premenopausal women with a BMI of less than 21 kg/m(2), women with a BMI exceeding 31 kg/m(2) had an RR of 0.54 (95% CI: 0.34, 0.85). In postmenopausal women, the RRs did not increase further when BMI exceeded 28 kg/m(2); the RR for these women was 1.26 (95% CI: 1.09, 1.46). The authors found little evidence for interaction with other breast cancer risk factors. Their data indicate that height is an independent risk factor for postmenopausal breast cancer; in premenopausal women, this relation is less clear. The association between BMI and breast cancer Varies by menopausal status. Weight control may reduce the risk among postmenopausal women.

The objective of the current study was to evaluate the effect of a subtilisin protease, without or with inclusion of carbohydrases, on digestibility and retention of energy and protein, as well as the solubilization and disappearance of non-starch polysaccharides (NSP) from corn-soybean meal based diets fed to broiler chickens. Two hundred eighty-eight Ross 308 male broiler chickens were used for the experiment. On d 14, the birds were weighed and allocated to 6 treatments and 8 replicates per treatment with 6 birds per replicate. Treatments were: 1) corn-soybean meal based control diet; 2) control diet plus supplemental protease at 5,000 (P5000) protease units (PU)/kg); 3) control plus 10,000 PU/kg protease (P10000); or control plus an enzyme combination containing xylanase, amylase, and protease (XAP) added to achieve protease activity of: 4) 2,500 PU/kg (XAP2500); 5) 5,000 PU/kg (XAP5000); or 6) 10,000 PU/kg (XAP10000). The enzymes in XAP were combined at fixed ratios of 10:1:25 of xylanase:amylase:protease. Data were analyzed by ANOVA and specific orthogonal contrasts between treatments were performed. Addition of xylanase and amylase increased (P < 0.05) the ileal digestibility of protein by 4.2% and 2.1% at XAP5000 and XAP10000, respectively (relative to P5000 and P10000, respectively), exhibiting a plateau after the XAP5000 dose. Increment (P < 0.05) in AME due to protease was evident, particularly in P10000. At the ileal level, XAP reduced (P < 0.05) the flow of insoluble xylose and arabinose, which indicates an increase in the solubilization of arabinoxylan polymers in the small intestine. Protease on its own reduced (P < 0.05) the flow of insoluble arabinose but did not affect the flow of insoluble xylose. XAP reduced (P < 0.05) the pre-cecal flow of insoluble and total glucose and galactose. It was concluded that whereas protease by itself improved nutrient utilization and increased solubilization of NSP components, at the lower dose, a combination of xylanase, amylase, and protease produced effects greater than those of protease alone.

Objective: To assess the effects of a language-sensitive diabetes education program on dietary changes and plasma lipid profiles. Method: Hispanic participants (n=13 males and 18 females, mean age = 54.00 + 10.68 years) participated in a 3-month health education study. Spearman correlation coefficients were used to evaluate correlations between dietary intake and laboratory measurements. Results: There were significant decreases in serum total cholesterol (-16.07 mg/dl, P= 0.035), HDL cholesterol (-3.23 mg/dl, P = 0.01), LDL cholesterol (-11.71 mg/dl, P = 0.013) and dietary cholesterol (-79.22 mg, P = 0.03). No significant mean change was observed in triglyceride and total cholesterol/HDL ratio. There was also a reduction in body mass index (BMI) (-0.15 kg/m2, P = 0.40), fasting glucose (-3.90 mg/dl, P = 0.43) and dual energy X-ray absorptiometry (DXA) total fat (-0.50, P = 0.97). Although not statistically significant, saturated fatty acids (-4.90 g, P = 0.19), polyunsaturated fatty acids (-3.31g, P = 0.11), and carbohydrate (-44.82 g, P = 0.22), decreased after three months. Conclusion: There were significant improvements in dietary intake and serum lipids after a three-month culture-specific diabetes education program [ABSTRACT FROM AUTHOR]

Introduction Few epidemiologic cohort studies on the etiology of chronic disease are powerful enough to distinguish racial and ethnic determinants from socioeconomic determinants of health behaviors and observed disease patterns. The Adventist Health Study-2 (AHS-2), with its large number of respondents and the variation in lifestyles of its target populations, promises to shed light on these issues. This paper focuses on some preliminary baseline analyses of responses from the first group of participants recruited for AHS-2. Methods We administered a validated and pilot-tested questionnaire on various lifestyle practices and health outcomes to 56,754 respondents to AHS-2, comprising 14,376 non-Hispanic blacks and 42,378 non-Hispanic whites. We analyzed cross-sectional baseline data adjusted for age and sex and performed logistic regressions to test differences between responses from the two racial groups. Results In this Seventh-day Adventist (Adventist) cohort, blacks were less likely than whites to be lifelong vegetarians and more likely to be overweight or obese. Exercise levels were lower for blacks than for whites, but blacks were as likely as whites not to currently smoke or drink. Blacks reported higher rates of hypertension and diabetes than did whites but lower rates of high serum cholesterol, myocardial infarction, emphysema, and all cancers. After we eliminated skin cancer from the analysis, the age-adjusted prevalence of cancer remained significantly lower for black than for white women. The prevalence of prostate cancer was 47% higher for black men than for white men. Conclusion The profile of health habits for black Adventists is better than that for blacks nationally. Given the intractable nature of many other contributors to health disparities, including racism, housing segregation, employment discrimination, limited educational opportunity, and poorer health care, the relative advantage for blacks of the Adventist lifestyle may hold promise for helping to close the gap in health status between blacks and whites nationally.

- Abstract
Hookahs have been rising in popularity in the United States (U.S.) especially among the youth yet not much research has been carried out to understand the various predictors of hookah use among youth. We have thus conducted a cross-sectional study with a mixed-methods triangulation design to identify the hookah use determinants at different levels of the Social Ecological Model among youth. Participants between the ages of 18-24 years were sampled purposively, between April to November 2023, following a snowballing technique from various communities in Virginia and California, United States. Data were collected via a survey, one-on-one interviews, and focus groups. The study had a total sample size of 20. We found that participants smoked for a median of 5 times in the past 30 days. The main determinants of hookah smoking included the limited knowledge of health effects and addiction, positive attitude, family and peer influence, use as a means to socially connect with others, culture, social acceptability, lack of education at school and work place, access to hookah bars and smoke shops, and lack of strict enforcement of laws to ban smoking of youth. Educational interventions should be implemented by public health authorities to target the youth, their social and communities to provide education on hookah harm and addictiveness and to restrict access to- and the production, distribution, marketing and sales of hookahs., (© 2024.

- Abstract
Background: Delays in the detection or treatment of postpartum hemorrhage can result in complications or death. A blood-collection drape can help provide objective, accurate, and early diagnosis of postpartum hemorrhage, and delayed or inconsistent use of effective interventions may be able to be addressed by a treatment bundle., Methods: We conducted an international, cluster-randomized trial to assess a multicomponent clinical intervention for postpartum hemorrhage in patients having vaginal delivery. The intervention included a calibrated blood-collection drape for early detection of postpartum hemorrhage and a bundle of first-response treatments (uterine massage, oxytocic drugs, tranexamic acid, intravenous fluids, examination, and escalation), supported by an implementation strategy (intervention group). Hospitals in the control group provided usual care. The primary outcome was a composite of severe postpartum hemorrhage (blood loss, ≥1000 ml), laparotomy for bleeding, or maternal death from bleeding. Key secondary implementation outcomes were the detection of postpartum hemorrhage and adherence to the treatment bundle., Results: A total of 80 secondary-level hospitals across Kenya, Nigeria, South Africa, and Tanzania, in which 210,132 patients underwent vaginal delivery, were randomly assigned to the intervention group or the usual-care group. Among hospitals and patients with data, a primary-outcome event occurred in 1.6% of the patients in the intervention group, as compared with 4.3% of those in the usual-care group (risk ratio, 0.40; 95% confidence interval [CI], 0.32 to 0.50; P<0.001). Postpartum hemorrhage was detected in 93.1% of the patients in the intervention group and in 51.1% of those in the usual-care group (rate ratio, 1.58; 95% CI, 1.41 to 1.76), and the treatment bundle was used in 91.2% and 19.4%, respectively (rate ratio, 4.94; 95% CI, 3.88 to 6.28)., Conclusions: Early detection of postpartum hemorrhage and use of bundled treatment led to a lower risk of the primary outcome, a composite of severe postpartum hemorrhage, laparotomy for bleeding, or death from bleeding, than usual care among patients having vaginal delivery.

- Abstract
Objective: To explore differences in obstetric practices and clinical outcomes of postpartum hemorrhage (PPH) in Nigerian facilities., Methods: A descriptive cross-sectional study of public health facilities providing maternal healthcare services in Nigeria. Surveys were conducted across 38 purposively sampled facilities (January 2020-March 2021) to collect information on obstetric practices related to the management of the third stage of labor, treatment of postpartum hemorrhage, and clinical outcomes related to postpartum hemorrhage in the preceding 12 months., Results: The median number of annual births per facility was 2230 (IQR, 1952-3283). The cesarean section rate was 21.6% (range 2.1%-52.6%). There was large variability in PPH rate (median 3%, range 0.4%-16.8%) and blood transfusions for PPH (median 2.8%, range 0.4%-48.6%) after vaginal birth. There was less variability for laparotomies (median 0.25%, range 0%-2.8%) and maternal deaths (median 0.11%, range 0%-0.64%) due to PPH after vaginal birth. The number of maternal deaths from all causes varied (median 0.27%, range 0%-3.5%). The rates of PPH and adverse maternal outcomes did not vary substantially between state or federal facilities, region, type of facility, and the number of clinical staff., Conclusion: Across the Nigerian facilities surveyed there was large variation in PPH rates and adverse maternal outcomes due to PPH. This variability remains largely unexplained and requires further insights and detailed data to gain a deeper understanding of the root causes and challenges to implement customized solutions to improve maternal outcomes., (© 2022 The Authors.

- Abstract
Objective: To check the quality of oxytocin and tranexamic acid-two recommended products for prevention and treatment of postpartum hemorrhage (PPH)-used in facilities taking part in an implementation research project to improve PPH diagnosis and management., Methods: Between September 2020 and August 2021, oxytocin and tranexamic acid products used in the study facilities in Kenya, Nigeria, South Africa, and Tanzania were collected and transported in cold storage for analysis. Samples were analyzed according to the International (oxytocin) and British Pharmacopeia (tranexamic acid) standards., Results: Of the 17 unique oxytocin products, 33 individual measurements were made. Only six unique products had adequate content and no related substances exceeding the recommended limits. Of 14 tranexamic acid samples, 10 showed adequate content. One product in Kenya and two products in Nigeria from different manufacturers had a high content of related substances, which classified them as substandard., Conclusion: While we were unable to investigate the origin regarding poor manufacturing or poor storage or both, the high number of substandard oxytocin samples is of great concern. Most of the tranexamic acid samples had adequate content but the presence of impurities in multiple products is worrying and requires further study., (© 2022 The Authors.

- Abstract
Trial Design: A randomised, parallel-group, double-blind, placebo-controlled multicentre study with health economic and nested qualitative studies to determine if mifepristone (Mifegyne
® , Exelgyn, Paris, France) plus misoprostol is superior to misoprostol alone for the resolution of missed miscarriage., Methods: Women diagnosed with missed miscarriage in the first 14 weeks of pregnancy were randomly assigned (1 : 1 ratio) to receive 200 mg of oral mifepristone or matched placebo, followed by 800 μg of misoprostol 2 days later. A web-based randomisation system allocated the women to the two groups, with minimisation for age, body mass index, parity, gestational age, amount of bleeding and randomising centre. The primary outcome was failure to pass the gestational sac within 7 days after randomisation. The prespecified key secondary outcome was requirement for surgery to resolve the miscarriage. A within-trial cost-effectiveness study and a nested qualitative study were also conducted. Women who completed the trial protocol were purposively approached to take part in an interview to explore their satisfaction with and the acceptability of medical management of missed miscarriage., Results: A total of 711 women, from 28 hospitals in the UK, were randomised to receive either mifepristone plus misoprostol (357 women) or placebo plus misoprostol (354 women). The follow-up rate for the primary outcome was 98% (696 out of 711 women). The risk of failure to pass the gestational sac within 7 days was 17% (59 out of 348 women) in the mifepristone plus misoprostol group, compared with 24% (82 out of 348 women) in the placebo plus misoprostol group (risk ratio 0.73, 95% confidence interval 0.54 to 0.98; p = 0.04). Surgical intervention to resolve the miscarriage was needed in 17% (62 out of 355 women) in the mifepristone plus misoprostol group, compared with 25% (87 out of 353 women) in the placebo plus misoprostol group (risk ratio 0.70, 95% confidence interval 0.52 to 0.94; p = 0.02). There was no evidence of a difference in the incidence of adverse events between the two groups. A total of 42 women, 19 in the mifepristone plus misoprostol group and 23 in the placebo plus misoprostol group, took part in an interview. Women appeared to have a preference for active management of their miscarriage. Overall, when women experienced care that supported their psychological well-being throughout the care pathway, and information was delivered in a skilled and sensitive manner such that women felt informed and in control, they were more likely to express satisfaction with medical management. The use of mifepristone and misoprostol showed an absolute effect difference of 6.6% (95% confidence interval 0.7% to 12.5%). The average cost per woman was lower in the mifepristone plus misoprostol group, with a cost saving of £182 (95% confidence interval £26 to £338). Therefore, the use of mifepristone and misoprostol for the medical management of a missed miscarriage dominated the use of misoprostol alone., Limitations: The results from this trial are not generalisable to women diagnosed with incomplete miscarriage and the study does not allow for a comparison with expectant or surgical management of miscarriage., Future Work: Future work should use existing data to assess and rank the relative clinical effectiveness and safety profiles for all methods of management of miscarriage., Conclusions: Our trial showed that pre-treatment with mifepristone followed by misoprostol resulted in a higher rate of resolution of missed miscarriage than misoprostol treatment alone. Women were largely satisfied with medical management of missed miscarriage and would choose it again. The mifepristone and misoprostol intervention was shown to be cost-effective in comparison to misoprostol alone., Trial Registration: Current Controlled Trials ISRCTN17405024., Funding: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment ; Vol. 25, No. 68.

- Abstract
Objective: To assess the cost-effectiveness of mifepristone and misoprostol (MifeMiso) compared with misoprostol only for the medical management of a missed miscarriage., Design: Within-trial economic evaluation and model-based analysis to set the findings in the context of the wider economic evidence for a range of comparators. Incremental costs and outcomes were calculated using nonparametric bootstrapping and reported using cost-effectiveness acceptability curves. Analyses were performed from the perspective of the UK's National Health Service (NHS)., Setting: Twenty-eight UK NHS early pregnancy units., Sample: A cohort of 711 women aged 16-39 years with ultrasound evidence of a missed miscarriage., Methods: Treatment with mifepristone and misoprostol or with matched placebo and misoprostol tablets., Main Outcome Measures: Cost per additional successfully managed miscarriage and quality-adjusted life years (QALYs)., Results: For the within-trial analysis, MifeMiso intervention resulted in an absolute effect difference of 6.6% (95% CI 0.7-12.5%) per successfully managed miscarriage and a QALYs difference of 0.04% (95% CI -0.01 to 0.1%). The average cost per successfully managed miscarriage was lower in the MifeMiso arm than in the placebo and misoprostol arm, with a cost saving of £182 (95% CI £26-£338). Hence, the MifeMiso intervention dominated the use of misoprostol alone. The model-based analysis showed that the MifeMiso intervention is preferable, compared with expectant management, and this is the current medical management strategy. However, the model-based evidence suggests that the intervention is a less effective but less costly strategy than surgical management., Conclusions: The within-trial analysis found that based on cost-effectiveness grounds, the MifeMiso intervention is likely to be recommended by decision makers for the medical management of women presenting with a missed miscarriage., Tweetable Abstract: The combination of mifepristone and misoprostol is more effective and less costly than misoprostol alone for the management of missed miscarriages., (© 2021 The Authors.

- Abstract
Objectives: To explore women's experiences of remifentanil or pethidine for labour pain and infant feeding behaviours at 6weeks post partum., Design: Qualitative postnatal sub-study to the randomised controlled trial of remifentanil intravenous patient controlled analgesia (PCA) versus intramuscular pethidine for pain relief in labour (RESPITE). Semistructured telephone interviews were conducted at 6 weeks post partum, and thematic analysis was undertaken., Setting: Women recruited to the RESPITE trial from seven UK hospitals., Participants: Eighty women consented and 49 (30 remifentanil group and 19 pethidine group) completed the interview., Results: Eight themes emerged which encompassed women's antenatal plans for pain management ( Birth Expectations ) through to their future preferences for pain relief ( Reflections for Future Choices ). Many women who used remifentanil felt it provided effective pain relief ( Effectiveness of Pain Relief ), whereas women in the pethidine group expressed more mixed views. Both groups described side effects, with women using pethidine frequently reporting nausea ( Negative Physiological Responses ) and women using remifentanil describing more cognitive effects ( Cognitive Effects ). Some women who used remifentanil reported restricted movements due to technical aspects of drug administration and fear of analgesia running out ( Issues with Drug Administration ). Women described how remifentanil enabled them to maintain their ability to stay focused during the birth ( Enabling a Sense of Control ). There was little difference in reported breastfeeding initiation and continuation between pethidine and remifentanil groups ( Impact on Infant Behaviour and Breastfeeding )., Conclusions: Qualitative insights from a follow-up study to a trial which explored experiences of intravenous remifentanil PCA with intramuscular pethidine injection found that remifentanil appeared to provide effective pain relief while allowing women to remain alert and focused during labour, although as with pethidine, some side effects were noted. Overall, there was little difference in reported breastfeeding initiation and duration between the two groups., Trial Registration Number: ISRCTN29654603., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background: About a third of women receiving pethidine for labour pain subsequently require an epidural, which provides effective pain relief but increases the risk of instrumental vaginal delivery. Remifentanil patient-controlled analgesia (PCA) in labour is an alternative to pethidine, but is not widely used. We aimed to evaluate epidural analgesia progression among women using remifentanil PCA compared with pethidine., Methods: We did an open-label, multicentre, randomised controlled trial in 14 UK maternity units. We included women aged 16 years or older, beyond 37 weeks' gestation, in labour with a singleton cephalic presentation, and who requested opioid pain relief. We randomly assigned eligible participants (1:1) to either the intravenous remifentanil PCA group (40 μg bolus on demand with a 2 min lockout) or the intramuscular pethidine group (100 mg every 4 h, up to 400 mg in 24 h), using a web-based or telephone randomisation service with a minimisation algorithm for parity, maternal age, ethnicity, and mode of labour onset. Because of the differences in routes of drug administration, study participants and health-care providers were not masked to the group allocation. The primary outcome was the proportion of women who received epidural analgesia after enrolment for pain relief in labour. Primary analyses were unadjusted and analysed by the intention-to-treat principle. This study is registered with the ISRCTN registry, number ISRCTN29654603., Findings: Between May 13, 2014, and Sept 2, 2016, 201 women were randomly assigned to the remifentanil PCA group and 200 to the pethidine group. One participant in the pethidine group withdrew consent, leaving 199 for analyses. The proportions of epidural conversion were 19% (39 of 201) in the remifentanil PCA group and 41% (81 of 199) in the pethidine group (risk ratio 0·48, 95% CI 0·34-0·66; p<0·0001). There were no serious adverse events or drug reactions directly attributable to either analgesic during the study., Interpretation: Intravenous remifentanil PCA halved the proportion of epidural conversions compared with intramuscular pethidine. This finding challenges routine pethidine use as standard of care in labour., Funding: National Institute for Health Research Clinician Scientist Award., (Copyright © 2018 Elsevier Ltd.

- Abstract
Exposure to diesel exhaust (DE) from vehicles and industry is hazardous and affects proper function of organ systems. DE can interfere with normal physiology after acute and chronic exposure to particulate matter (PM). Exposure leads to potential systemic disease processes in the central nervous, visual, hematopoietic, respiratory, cardiovascular, and renal systems. In this review, we give an overview of the epidemiological evidence supporting the harmful effects of diesel exhaust, and the numerous animal studies conducted to investigate the specific pathophysiological mechanisms behind DE exposure. Additionally, this review includes a summary of studies that used biomarkers as an indication of biological plausibility, and also studies evaluating new technology diesel exhaust (NTDE) and its systemic effects. Lastly, this review includes new approaches to improving DE emissions, and emphasizes the importance of ongoing study in this field of environmental health., (Copyright © 2018 Elsevier Ltd.

- Abstract
Among cancers in American women, breast cancer (BC) has the second highest incidence and mortality. The association of BC with diet has been inconsistent. Studies that evaluate associations with dietary patterns are less common and reflect an individual's whole diet. We associated dietary patterns with the risk of BC in American women of the Adventist Health Study-2 (AHS-2), a prospective cohort of 96 001 subjects recruited between 2002 and 2007. Answers to a previously validated FFQ were used to classify subjects to vegan, lacto-ovo-vegetarian, pesco-vegetarian, semi-vegetarian and non-vegetarian dietary patterns. Incident BC were identified by matching AHS-2 subjects to data from forty-eight state cancer registries. Statistical analyses used proportional hazard regression analyses with covariates that were chosen a priori. From 50 404 female participants (26 193 vegetarians), we identified 892 incident BC cases, with 478 cases among vegetarians. As compared with non-vegetarians, all vegetarians combined did not have a significantly lower risk (hazard ratio (HR) 0·97; CI 0·84, 1·11; P=0·64). However, vegans showed consistently lower (but non-significant) point estimates when compared with non-vegetarians (all cases: HR 0·78; CI 0·58, 1·05; P=0·09). In summary, participants in this cohort who follow a vegetarian dietary pattern did not experience a lower risk of BC as compared with non-vegetarians, although lower risk in vegans is possible. These findings add to the very limited literature associating vegetarian diets with BC risk and can assist nutritionists when evaluating the impact of these diets. The findings will also motivate further evaluation of vegan diets and their special characteristics.

- Abstract
Objectives: The primary objective of this study was to identify which patient demographic, patient health, and hospital characteristics were associated with in-hospital mortality. A secondary objective was to determine the relative influence of these characteristics on mortality., Design and Setting: Public-use data for 2005-2010 were used in this retrospective, cross-sectional analysis of discharges from nonfederal, general acute hospitals in California. A staged logistic regression approach was used to examine the relative influence of variables associated with in-hospital mortality., Patients: A total of 1,213,219 patient discharges for adults (aged ≥18 yrs) having International Classification of Diseases-9 diagnosis and procedure codes indicating severe sepsis., Intervention: None., Measurements and Main Results: Patient demographics (age, gender, race, ethnicity, and payer category), patient health status (acute transfer, Charlson-Deyo comorbidity index, and organ failures), and hospital characteristics (ownership type, teaching status, bed size, annual patient days, acute discharges, emergency department visits, inpatient surgeries, severe sepsis as a percentage of all discharges, and year) were obtained from the California Office of Statewide Health Planning and Development. Overall, in-hospital mortality was 17.8%. There was a steady annual increase in the number of sepsis discharges, but a decrease in mortality throughout the study period. Mortality increased with age and was associated with white race, and Medicaid (Medi-Cal) and private insurance. Patient health status additionally explained inpatient mortality. Hospital volume measures were statistically significant in regression analysis, whereas static structural measures were not. There were modest associations between measures of annual treatment volume and likelihood of inpatient mortality, notably decreasing likelihood with more acute discharges and with greater severe sepsis volume., Conclusions: Although patient demographics and health status are the most important predictors of in-hospital mortality of patients with severe sepsis, hospital characteristics do play a substantial role. Findings regarding hospital volume can be used to improve processes and improve patient outcomes.

- Abstract
Purpose: This study was designed to assess the feasibility of culturally and language-sensitive diabetes education as a way to increase physical activity and to improve health/diabetes management in a group of Spanish-speaking Hispanics in the Inland Empire region of Southern California., Methods: En Balance is a culturally sensitive diabetes education program designed for Spanish-speaking Hispanic adults. The 3-month educational intervention assessed 16 males and 23 females living in Riverside and San Bernardino counties of Southern California. Baseline and 3-month evaluations of physical activity were assessed using the validated Arizona Activity Frequency Questionnaire., Results: After 3 months on the En Balance program, there was a significant increase in moderate intensity physical activity energy expenditure (M = 368 ± 894 kcal/day, P < 0.01) and high intensity physical activity energy expenditure (M = 405 ± 2569 kcal/day, P = 0.05) compared to baseline and significant reductions in A1C (-0.90%, P = 0.01), total cholesterol (-13.44 mg/dl, P = 0.01), LDL cholesterol (-10.28 mg/dl, P = 0.03), and waist circumference (-1.52 cm, P = 0.04)., Conclusion: En Balance program resulted in significant mean increases in both moderate and high intensity physical activity energy expenditure among this group of Hispanic diabetic participants, indicating that despite a general pattern of low physical activity in this group, an intervention that stresses both nutrition and exercise in culturally sensitive ways can positively impact participant's physical activity levels as well as impact nutritional changes.
