High-Speed Rail and Energy Productivity: Evidence from China

Using the difference-in-differences method combined with the propensity score matching, this study identifies the causal relationship between high-speed rail (HSR) and energy productivity in China. Furthermore, we investigate the mechanism through which HSR affects energy productivity, as well as the heterogeneity of the impact across quantiles and distances. The results show that HSR connection contributes to the improvement of energy productivity. This finding is consolidated after a potential endogeneity problem is addressed using the instrumental variable method and a variety of potential confounders are controlled through a series of robustness checks. On average, the marginal impact of HSR on energy productivity is approximately 9%. Moreover, HSR connection cannot be completely substituted by traditional railway and aviation in improving energy productivity. The heterogeneity analysis suggests that the positive energy productivity effect of HSR gradually decreases with an increasing distance to the nearest HSR station. In addition, HSR network accessibility has a significant positive effect on energy productivity, while technological innovation mediates the relationship between HSR development and energy productivity. We propose that to achieve the long-term improvement of energy productivity, policymakers should comprehensively consider both transit-oriented development and ecology-oriented development modes.

Psychosocial and sociodemographic factors associated with gestational blood glucose levels in women attending public hospitals: Results from baseline of MAASTHI cohort.

Understanding psychosocial environment is important for improving maternal and fetal health outcomes during pregnancy. We aimed to identify the association between gestational blood glucose levels and psychosocial and demographic factors in pregnant women. In the MAASTHI pregnancy cohort in Bengaluru, we assessed depressive symptoms, and social support using validated scales at baseline in first trimester. A 2-hour 75 g oral glucose tolerance test (OGTT) was administered between 24-36 weeks of gestation. We examined the relation between psychosocial factors assessed at baseline and gestational blood glucose levels in second/third trimester using multivariate linear regression and explored association between serum cortisol and gestational blood glucose levels in subgroup samples. We found that 9% of pregnant women had depressive symptoms and 14.3% had Gestational Diabetes Mellitus (GDM). Psychosocial factors, including depressive symptoms, have a significant correlation with gestational fasting(β = 0.12, p-value<0.05) and postprandial blood sugar level(β = 0.23, p-value<0.05) and poor social support were found to have a significant association with gestational fasting blood glucose levels(β = 1.45, p-value <0.05) and postprandial blood sugar levels(β = 2.60, p-value <0.05). The sociodemographic factors such as respondent education, occupation, social and economic status were associated with gestational blood sugar after adjusting for potential confounder variables. Depressive symptoms and poor social support earlier in pregnancy were significantly associated with increased gestational blood glucose levels. Early detection and recognition of modifiable psychosocial risk factors can reduce glucose intolerance during pregnancy. Evaluating the benefits of screening for psychosocial factors and timely management of gestational diabetes mellitus can be helpful in India.

The association of various physical activities with erectile dysfunction: NHANES 2001-2004.

The relationship between erectile dysfunction (ED) and physical activity has been established in several previous studies, but there is little information on the specific forms of activity that affect ED. The objective of this study was to evaluate the relationship of 4 exercise categories and 2 activity intensities with ED in US men. We used data sets from the National Health and Nutrition Examination Survey, 2001-2004. We used odds ratios (ORs) and multivariate logistic regression models to investigate the relationship between physical activity and ED. We also conducted subgroup analyses by age and controlled for potential confounder variables using propensity score matching analyses. The primary outcome was ED as assessed through self-reporting. An overall 4094 adult men were included in the study. Adjusted multivariate regression models indicated that men who participated in monthly muscle-strengthening activities (OR = 0.75, P = .031), leisure activities (OR = 0.76, P = .024), or vigorous activities (OR = 0.64, P = .001) had a lower risk of ED. The subgroup analysis showed that among those ≥40 yearsold, muscle-strengthening activity (OR = 0.67, P = .005), leisure activity (OR = 0.72, P = .006), and vigorous activity (OR = 0.50, P < .001) were negatively associated with ED. After adjustment of propensity score matching, leisure activity and vigorous activity were also associated with a lower risk of ED, and muscle-strengthening activity was not significantly associated with ED. Our findings could provide guidance to clinicians in helping patients with ED develop exercise programs. We explored the relationship of 4 types and 2 intensities of exercise with ED, using a large sample size and sampling weights to produce representative data. However, this is only a cross-sectional study. Active monthly participation in leisure and vigorous activity is associated with the maintenance of erectile function, while the relevance of muscle-strengthening activities needs further study.

One-step versus two-step screening for diagnosis of gestational diabetes mellitus in Iranian population: A randomized community trial.

There is considerable worldwide controversy regarding optimal screening and diagnostic approaches for GDM. This study aimed to compare the prevalence, maternal and neonatal outcomes of a One-step with a Two-step approach for the screening and diagnosis of GDM in a large community sample of pregnant women. We conducted a secondary analysis of a randomized community non-inferiority trial of GDM screening in Iran. For the current study, all pregnant women who met the inclusion criteria were randomized into two groups for GDM screening. The first group of women (n = 14611) was screened by a One-step screening approach [75-g 2-h oral glucose tolerance test (OGTT)] and the second group (n = 14160) by a Two-step method (the 50-g glucose challenge test followed by the 100-g OGTT). All study participants were followed up until delivery, and the adverse maternal and neonatal outcomes were recorded in detail. GDM was diagnosed in 9.3% of the pregnant women who were assigned to the One-step and in 5.4% of those assigned to the Two-step approach with a statistically significant difference between them (p < 0.001). Intention-to-treat analyses showed no significant differences between the One-step and the Two-step group in the unadjusted risks of the adverse pregnancy outcomes of macrosomia, primary cesarean-section, preterm birth, hypoglycemia, hypocalcemia, hyperbilirubinemia, preeclampsia, neonatal intensive care unit admission, birth trauma, low birth weight, and intrauterine fetal death. Results remained unchanged after adjustment for potential confounder variables including gestational age at enrollment and delivery, maternal body mass index, gestational weight gain, type of delivery, treatment modality, and GDM diagnosis in the first trimester. We found that although the rates of GDM more than doubled with the One-step strategy, the One-step approach was similar to the Two-step approach in terms of maternal and neonatal outcomes. These findings may warn that more caution should be exercised in adopting the One-step method worldwide. Future research is needed to assess the long-term harm and benefits of those approaches to GDM screening for both mothers and their offspring. https://www.irct.ir/trial/518, identifier (IRCT138707081281N1).

Abstract HUP6: Community Deprivation And Healthcare Access/Utilization In Patients With Carotid Stenosis: Results From The All Of Us Research Program

Background: Social determinants of health are emerging as a key group of risk factors for cerebrovascular disease. Carotid artery stenosis (CAS) is an important risk factor for ischemic stroke. We hypothesize that community deprivation, an exposure that captures several social determinants for health, leads to significant disparities in healthcare access in patients with known CAS. Methods: We conducted a cross-sectional study within the All of Us Research Program, a prospective population study that aims to enroll 1 million Americans. We included study participants with CAS, as defined by validated ICD-9/10 codes. We evaluated access to healthcare using 5 metrics included in the Health Care Access and Utilization Survey (Table 1). We evaluated community deprivation using the Deprivation Index, a novel compound metric developed by the American Community Survey. We tested for association between tertiles of the Deprivation Index (labeled low, intermediate and high community deprivation) and health care access using multivariable models adjusting for potential confounders. Results: Of 333,845 participants enrolled in All of Us, we identified 2,465 (0.74%) participants with CAS (mean age 69, 53% female). Of these, 259 (10.5%) could not afford prescription medication, 132 (5.4%) could not afford specialist care, 144 (5.8) skipped medications, 109 (4.4%) could not afford to follow up care and 97 (3.9%) could not afford mental health care. In unadjusted analysis, higher community deprivation was associated with a higher prevalence of all 5 evaluated indicators of poor access to health. In multivariable analysis adjusted for potential confounder variables, difficulty affording prescription medication, specialist care and follow up care remained statistically significant (Table 1). Conclusion: Among persons with CAS enrolled in All of Us, community deprivation was associated with a lower likelihood of accessing and utilizing important healthcare services.

Associations between responsive parental behaviours in infancy and toddlerhood, and language outcomes at age 7 years in a population-based sample.

A wealth of evidence supports the important role high-quality parent-child interactions play in children's early language acquisition. However, the impact on later language outcomes remains unclear. To examine the associations between responsive parental behaviours across the early years and child language outcomes at age 7 years with families from an Australian longitudinal cohort study (N = 1148, 50% female). At child ages 12, 24 and 36 months, parents completed a self-report measure of responsive parental behaviours. Child language was directly assessed at age 7 using the Clinical Evaluation of Language Fundamentals, 4th edition (CELF-4), Australian Standardisation. Linear regression was used to examine associations between responsive parental behaviours from 12 to 36 months (consistently high, inconsistent and consistently low responsive parental behaviours at the three time points) and language scores at age 7 years. Adjusted models were run, including the following potential confounders: child sex; birth weight; birth order; maternal education; socio-economic disadvantage; non-English-speaking background; family history of speech-language problems; mother's vocabulary score; maternal mental health score; and mother's age at birth of child. A final adjusted model was run, including the potential confounder variables as well as adjusting for children's earlier language skills. Linear regression results showed children with parents who rated high on responsive parental behaviours at all three time points had higher mean language scores at age 7 than children whose parents reported low responsive parental behaviours across early childhood. This association attenuated after adjusting for earlier child language skills. Findings support the consistent use of responsive parental behaviours across the very early years of childhood to support long-term language outcomes. Findings also suggest that models of surveillance and support which monitor and assist families at multiple time-points over the early years are likely to be most effective for preventing ongoing language difficulties. What is already known on this subject There is extensive evidence consistently demonstrating the important contribution of aspects of parent-child interaction, specifically responsive parental behaviours, to children's language development. What this paper adds to the existing knowledge Understanding the cumulative benefit of responsive parent-child interactions across the very early years may help to inform preventive interventions and service delivery models for supporting young children's language development. This study demonstrates in a large, population-based cohort the contribution of consistency of responsive parental behaviours during infancy and toddlerhood to school-age language outcomes, accounting for other child, family and environmental factors. Capturing regular parent behaviours via self-report during the early years may be a more efficient and less costly method than parent-child interaction observations to monitor the home language-learning environment during routine developmental checks. What are the potential or actual clinical implications of this work? Findings support the need for surveillance of children and families in the early years, ensuring that intervention occurs when families need it most, that is, support is responsive to changing needs and that nuanced advice and support strategies are provided to activate positive developmental cascades. Capturing both parent behaviours and child language may assist clinicians to identify those families who may benefit from parent-child interaction intervention.

The patient education strategy “learning and coping” improves adherence to cardiac rehabilitation in primary healthcare settings: a pragmatic cluster-controlled trial

BackgroundAdherence and completion of programmes in educational and physical exercise sessions is essential in cardiac rehabilitation (CR) to obtain the known benefits on morbidity, mortality, risk factors, lifestyle, and quality of life. The patient education strategy “Learning and Coping” (LC) has been reported to positively impact adherence and completion in a hospital setting. It is unknown if LC has impact on adherence in primary healthcare settings, and whether LC improves self-management. The aim of this pragmatic primary healthcare-based study was to examine whether patients attending CR based on LC had a better adherence to patient education and physical exercise, higher program completion rate, and better self-management compared to patients attending CR based on a consultation program Empowerment, Motivation and Medical Adherence (EMMA).MethodA pragmatic cluster-controlled trial of two types of patient education LC and EMMA including ten primary healthcare settings and 514 patients (LC, n = 266; EMMA, n = 248) diagnosed with ischaemic heart disease discharged from hospital and referred to CR between August 1, 2018 and July 31, 2019. Adherence was defined as participation in ≥ 75% of provided sessions. Completion was defined as patients attended the final interview at the end of the 12-weeks programme. Patient Activation Measure (PAM) was used to obtain information on a person's knowledge, skills and confidence for self-management. PAM questionnaire was completed at baseline and 12-weeks follow-up. Multiple and Linear regression analyses adjusted for potential confounder variables and cluster effect were performed.ResultPatients who followed CR based on LC had a higher adherence rate to educational and physical exercise sessions compared to patients who followed CR based on EMMA (p < 0.01). High-level of completion was found at the end of CR with no statistically significant between clusters (78.9% vs. 78.2%, p > 0.05). At 12-weeks, there was no statistical differences in PAM-score between clusters (p > 0.05).ConclusionThis study indicates that the LC positively impacts adherence in CR compared to EMMA. We found non-significant difference in completing CR and in patient self-management between the two types of patient education. Future studies are needed to investigate if the higher adherence rate achieved by LC in primary healthcare settings translates into better health outcomes.

Birth Size Outcomes in Relation to Maternal Blood Levels of Some Essential and Toxic Elements.

Exposures to toxic trace elements and deficiencies of essential trace elements during pregnancy may impact fetal growth. This study was conducted to determine the association between maternal blood levels of essential elements including manganese (Mn), copper (Cu), and zinc (Zn) and toxic elements including arsenic (As), cadmium (Cd), and lead (Pb) at the first trimester with neonatal anthropometric parameters. This cross-sectional study was conducted in 2019-2020 in Isfahan, Iran. Overall, 263 mother-infant pairs were recruited in the first trimester of pregnancy. Maternal whole blood was collected, and essential and toxic elements were determined by mass spectrometry (ICP-MS)-based method. Birth size measurements were performed according to standardized protocols. Geometric means and standard deviations of maternal blood concentrations of Mn, Cu, Zn, As, Cd, and Pb were 3.94 ± 0.82, 5.22 ± 0.57, 7.67 ± 0.58, 2.21 ± 0.77, - 0.59 ± 0.98, and 3.23 ± 0.72 µg/l, respectively. Mean age of mothers was 29.94 ± 5.22 years. Thirty-one (12.1%) neonates were preterm. Maternal blood Pb levels were negatively correlated with birth weight (β = - 0.22 (CI 95%: - 0.38, - 0.05) p = 0.010) and marginally with birth head circumference (β = - 0.14(CI 95%: - 0.29, 0.02), P = 0.094) after adjustment for potential confounder variables. There was no significant association between Mn, Cu, Zn, As, Cd, and birth size measurements. Reverse association was found between maternal blood Pb levels and birth weight and birth head circumference. There is limited evidence related to the association between essential and toxic elements during pregnancy with birth size measurements and pregnancy disorders. More studies are suggested to assess of the effect of the trace elements and birth outcomes.

Assessment of milk yield and composition, early reproductive performance, and herd removal in multiparous dairy cattle based on the week of diagnosis of hyperketonemia in early lactation

The purpose of this retrospective cohort study was to evaluate the effects of the timing of hyperketonemia (HYK) diagnosis during early lactation on milk yield and composition, reproductive performance, and herd removal. Plasma β-hydroxybutyrate (BHB) was measured twice a week during the first 2 wk of lactation in 362 multiparous Holstein cows for the diagnosis of HYK. In each week, cows were diagnosed as HYK positive (HYK+) if the plasma BHB concentrations were ≥1.2 mmol/L in at least one of the tests for the week evaluated. Milk-related outcomes (first 10 monthly milk tests) included milk yield, milk fat and protein content, milk urea nitrogen (MUN), and linear score of somatic cell count. Other performance outcomes of interest included risk of pregnancy within 150 d in milk (DIM) and herd removal (i.e., culling or death) within 300 DIM. Statistical models were built separately for cows diagnosed with HYK during the first week of lactation (wk1) and for cows diagnosed during the second week of lactation (wk2). All models for wk2 were adjusted by HYK diagnosed in wk1, along with other potential confounder variables. The association between HYK in each week and milk-related outcomes was assessed using generalized estimated equation models that accounted for repeated measures. Time to pregnancy and time to herd removal were analyzed using Cox's proportional hazard regression models. Seventy-eight cows (21.5%) tested positive for HYK during wk1, 60 cows (16.6%) in wk2, and 29 cows (8.0%) in both weeks. Hyperketonemia during wk1 was associated with a milk yield reduction of 3.7 kg [95% confidence interval (CI): -6.67 to -0.76] per cow per day throughout the lactation. Meanwhile, we did not observe evidence of an association between HYK diagnosed during wk2 and milk yield. During the first 2 monthly milk tests, cows diagnosed as HYK+ in wk1 had greater fat (0.42%; 95% CI: 0.16 to 0.67) and MUN (0.75 mg/dL; 95% CI: 0.26 to 1.24) content in milk than HYK-negative (HYK-) cows. We did not detect any evidence of an association between HYK diagnosed in wk2 and these outcomes. The HYK+ cows in wk1 had a 30% [hazard ratio (HR) = 0.70; 95% CI: 0.48 to 1.01] lower risk of pregnancy within 150 DIM and 2.48 times (95% CI: 1.63 to 2.89) higher risk of herd removal within 300 DIM than HYK- cows. Conversely, no evidence of association was observed between HYK+ cows in wk2 and risk of pregnancy by 150 DIM (HR = 0.98; 95% CI: 0.64 to 1.51) or removal from the herd within 300 DIM (HR = 0.91; 95% CI: 0.52 to 1.60). Our findings indicate that HYK diagnosed during wk1 of lactation is associated with negative performance in terms of milk yield, reproduction, and herd removal. No evidence of association was found for the same outcomes when HYK was diagnosed in wk2. Our results suggest the need to consider the timing when HYK is diagnosed when investigating its association with performance outcomes.

A transdiagnostic evaluation of cortical inhibition in severe mental disorders using Transcranial Magnetic Stimulation

Multiple lines of investigations suggest the presence of cortical inhibition aberrations as central to the phenotypic manifestations of severe mental disorders. Transcranial Magnetic Stimulation (TMS) combined with electromyography can characterize these inhibitory processes in the motor cortex with satisfactory temporal precision. We examined TMS-evoked short- (SICI) and long-interval intracortical inhibition (LICI) and cortical silent period (CSP) as markers of GABAA- (SICI) and GABAB-mediated (LICI and CSP) cortical neurotransmission in symptomatic individuals with mania (n = 40), schizophrenia (n = 76), unipolar depression (n = 86), and OCD (n = 43), and compared them against similar recordings in healthy subjects (n = 125). We hypothesized transdiagnostic GABAA deficits across all the clinical groups and diagnosis-specific GABAB alterations in mania (increased) and OCD (decreased). After controlling for potential confounder variables (gender, education, benzodiazepine prescription, and motor threshold) using the ANCOVA, we observed no significant group difference in SICI (F = 1.04, P = 0.38), but a significant group effect in LICI (F = 16.29, P < 0.001) and CSP (F = 3.02, P = 0.018). Post-hoc analyses revealed that LICI was significantly reduced in OCD but increased in mania and schizophrenia with reference to the healthy group. Similarly, CSP was significantly reduced in OCD and depression groups as compared to the reference group. We observed that LICI and CSP, both followed similar descending gradients from mania through schizophrenia and depression to OCD; with significant elevation in mania, and reduction in depression and OCD, as compared to the healthy group. This pattern of GABAB-mediated cortical inhibition aberrations needs independent validation as potential state-markers of distinct clinical categories.

The Use of Contraception and Adolescent Fertility in Indonesia

INTRODUCTION: Fertility in adolescents is closely related to the incidence of early marriage which will have an impact on increasing the incidence of pregnancy in adolescents so that it will directly affect the health of mothers and babies. The younger the age at marriage, the higher the fertility rate.&#x0D; AIM: This study aimed to determine the relationship between contraception and fertility among ado­lescents.&#x0D; METHODS: This quantitative study used a cross-sectional design. The population of this study was adolescents aged 15–19 years in Indonesia. The total sample of 7,547 adolescents was selected from the 2017 Indonesia Demographic and Health Survey (IDHS). Multivariate analysis using binary logistic regression was used to analyze the independent variable (contraception use) on the dependent variable (fertility) with education, work status, region, age at first sexual intercourse, economic status, and marital status as the controlled variables.&#x0D; RESULTS: Multiple logistic regression analysis was used to report the relationship between independent and dependent variables controlled by potential confounder variables. The results showed that the odds ratio of contraceptives users was 46 times compared to non-user after being controlled by confounding variables (AOR=4.8; 95%CI 33.857 – 441.046) after controlled by economic status, age at first exual intercourse, and marital status.&#x0D; CONCLUSION: The relationship between contraceptive use and fertility in adolescents is affected by confounding variables such as age at first sexual intercourse, economic status, and marital status. In addition, the odds ratio of contraceptives users was 46 times compared to non-users after being controlled by confounding variables.

Associations between interpersonal dependency and severity of prolonged grief disorder symptoms in bereaved surviving family members

BackgroundSeveral studies have shown that interpersonal dependency is a risk factor for prolonged grief disorder (PGD), a disorder that has been recently approved by the American Psychiatric Association Assembly for inclusion in the Diagnostic and Statistical Manual of Mental Disorders—5—Text Revision (DSM-5-TR). Nevertheless, it remains unclear whether this relationship is independent of depression, which may also be related to both loss and interpersonal dependency. Furthermore, anaclitic dependency (maladaptive and immature) compared to relatedness (more adaptive and mature) dependency, and the relationships between these types of dependency and PGD, have not been examined. The aim of the present study was to determine how anaclitic and relatedness dependency are associated with PGD symptom severity, controlling for depressive symptom severity, over and above potential sociodemographic and loss-related confounder variables. MethodsParticipants (N = 241) bereaved after the death of a family member from 0.5 to 8 years before the survey (M = 3.36, SD = 2.02) completed the Depressive Experiences Questionnaire, the Patient Health Questionnaire—9, and the Prolonged Grief Disorder—13 scale (PG-13). ResultsA hierarchical regression analysis confirmed that anaclitic dependency is positively associated with PGD symptom severity, even when controlling for depression severity and other potential confounder variables. There was no significant association between relatedness dependency and PGD. ConclusionsTo assess the risk of PGD in individuals bereaved after the death of a family member, it is important to assess anaclitic dependency.

Triglycerides to high-density lipoprotein cholesterol ratio is superior to triglycerides and other lipid ratios as an indicator of increased urinary albumin-to-creatinine ratio in the general population of China: a cross-sectional study

BackgroundDyslipidemia contributes to the pathogenesis of renal dysfunction. Previous research demonstrated that triglycerides (TG), instead of other individual lipid indexes, has a significant link with elevated urinary albumin-to-creatinine ratio (UACR). However, it is unclear whether lipid ratios are superior indicators of increased UACR compared with TG. This research is to determine whether there are close relationships of lipid ratios with UACR in a general population.Methods35,751 participants from seven centers across China were enrolled. UACR equal or higher than 30 mg/g was recognized as increased albuminuria. The associations of TG, low-density lipoprotein cholesterol (LDL-C)/ high-density lipoprotein cholesterol (HDL-C), TG/HDL-C and non-high-density lipoprotein cholesterol (non-HDL-C)/HDL-C with increased UACR were evaluated by linear and logistic regression analyses in females and males separately.ResultsThere were 3692 (14.8%) female subjects, and 1307 (12.0%) male subjects characterized as having increased UACR. There were significantly differences in TG/HDL-C and non-HDL-C/HDL-C between the normal UACR group and the increased UACR group, while LDL-C/HDL-C was not. Furthermore, linear regression analysis was implemented and showed that TG and TG/HDL-C were both positively related to UACR even after a variety of potential confounders were adjusted regardless of sexes, while the correlation between non-HDL-C/HDL-C and elevated UACR were only significant in females. Further analyses utilizing logistic regression demonstrated that compared with non-HDL-C/HDL-C and TG, TG/HDL-C showed the strongest association with increased UACR (quartile 1 of TG/HDL-C as a reference; OR [95% CI] of quartile 4: 1.28 [1.13–1.44] in women, 1.24 [1.02–1.50] in men) after fully adjusting for potential confounding factors. Stratified analyses revealed that in males who were overweight and in females who were overweight or over 55 years or had prediabetes or prehypertension, TG/HDL-C had significant associations with abnormal UACR.ConclusionsCompared with TG and other routine lipid ratios, TG/HDL-C is a superior indicator for increased UACR.

Birth weight associations with DNA methylation differences in an adult population

ABSTRACT The Developmental Origins of Health and Disease (DOHaD) theory predicts that prenatal and early life events shape adult health outcomes. Birth weight is a useful indicator of the foetal experience and has been associated with multiple adult health outcomes. DNA methylation (DNAm) is one plausible mechanism behind the relationship of birth weight to adult health. Through data linkage between Generation Scotland and historic Scottish birth cohorts, and birth records held through the NHS Information and Statistics Division, a sample of 1,757 individuals with available birth weight and DNAm data was derived. Epigenome-wide association studies (EWAS) were performed in two independently generated DNAm subgroups (nSet1 = 1,395, nSet2 = 362), relating adult DNAm from whole blood to birth weight. Meta-analysis yielded one genome-wide significant CpG site (p = 5.97x10−9), cg00966482. There was minimal evidence for attenuation of the effect sizes for the lead loci upon adjustment for numerous potential confounder variables (body mass index, educational attainment, and socioeconomic status). Associations between birth weight and epigenetic measures of biological age were also assessed. Associations between lower birth weight and higher Grim Age acceleration (p(FDR) = 3.6x10−3) and shorter DNAm-derived telomere length (p(FDR) = 1.7x10−3) are described, although results for three other epigenetic clocks were null. Our results provide support for an association between birth weight and DNAm both locally at one CpG site, and globally via biological ageing estimates.

Extended healthy lifestyle index and colorectal cancer risk in the Moroccan population.

Little is known about the combined effect of different lifestyle factors on CRC incidence among populations living in developing countries. In this study, we sought to create an Extended Healthy Lifestyle Index (EHLI) and to investigate its association with CRC risk in the Moroccan population. A large case-control study including 1516 cases and 1516 controls, matched on age, sex and center were recruited in 5 Moroccan university hospital centers between 2009 and 2017. EHLI scores, including 9 modifiable factors (smoking, alcohol consumption, physical activity intensity, BMI, fruit and vegetables consumption, drinks that promote weight gain, red and processed meat, relatively unprocessed cereals and/or pulses, and dairy products consumption) were assigned to lifestyle information derived from the participants. We assessed the score based on the answers on each of the nine lifestyle components as unhealthy/un-compliant (0 point), healthy/compliant (1 point) and 0.5 for partial compliance to the recommendation. Conditional logistic regression models were used to assess the association between the EHLI and CRC risk and to estimate multivariate ORs and their 95% confidence intervals (CIs). All potential confounder variables were considered. After adjusting for potential confounding factors, a significant decrease in the risk of overall CRC was observed when comparing the highest EHLI category with the lowest index category (0.39, 95% CI: 0.33-0.47). These results did not differ by colon or rectum subsite. Combined healthy lifestyle factors are associated with a significantly lower incidence of CRC in Moroccan populations. Prevention strategies should consider targeting of multiple lifestyle factors.

Competing risks analysis of the association between perioperative blood transfusion and long-term outcomes after resection of colorectal cancer.

Despite numerous reports over three decades, the association between perioperative blood transfusion and long-term outcomes after resection of colorectal cancer remains controversial. This cohort study used competing risks statistical methods to examine the association between transfusion and recurrence and colorectal cancer-specific death after potentially curative and noncurative resection. A hospital database provided prospectively recorded clinical, operative and follow-up information. All surviving patients were followed for at least 5years. Data were analysed by multivariable competing risks regression. From 2575 patients in the period 1995-2010 inclusive, after exclusions, 2334 remained for analysis. Among 1941 who had a potentially curative resection and 393 who had a noncurative resection the transfusion rates were 24.9% and 33.6%, respectively. After potentially curative resection there was no significant bivariate association between transfusion and recurrence (HR 0.93, CI 0.74-1.16, P=0.499) or between transfusion and colorectal cancer-specific death (HR 1.04, CI 0.82-1.33, P=0.753). After noncurative resection there was no significant association between transfusion and cancer-specific death (HR 0.93, CI 0.73-1.19, P=0.560). Multivariable models showed no material effect of potential confounder variables on these results. The competing risks findings in this study showed no significant association between perioperative transfusion and recurrence or colorectal cancer-specific death.

Severe maternal morbidity among women with a history of cesarean section at a tertiary referral teaching hospital in the southeast of Iran

ObjectivesAlthough the cesarean section (C-section) is known as a lifesaving procedure, it can also increase the risk of maternal mortality and morbidity. This study was conducted to achieve two objectives: (1) determination of maternal near miss (MNM) indicators and pregnancy outcomes among women with a history of C-section and (2) investigation of the women's experience of near miss events during childbirth to provide a deeper understanding of the weaknesses of care delivery process. Study designThe present study was conducted using a prospective cross-sectional study using the World Health Organization (organ system dysfunction–based) criteria. MethodsAll subjects were women at more than 22 weeks of gestation who gave birth in Ali ibn Abi Talib Hospital, Zahedan, Iran, and were referred to this hospital for childbirth or those within 42 days of pregnancy termination. Logistic regression was used to predict the risk factors for severe maternal outcomes (SMOs). ResultsNearly 58% of all MNM cases were related to women with a history of C-section. The MNM ratio was estimated at 8.04 per 1000 live births. Moreover, the frequent causes of SMOs were reported as severe hemorrhage (58.3%), severe pre-eclampsia/eclampsia (27.8%), medical condition (8.3%), and sepsis or severe systemic infection (5.6%). Abnormally invasive placenta (61%) was the most common cause of severe hemorrhage. After adjustment for potential confounder variables, the hemoglobin level of <11 g/dl (odds ratio [OR] = 0.18, 95% confidence interval [CI] = 0.09–0.36) and place of residence (OR = 0.41, 95% CI = 0.19–0.90) remained as independent risk factors for SMOs in the final model of multivariate analysis. ConclusionA risk assessment system is needed to diagnose and manage the risk factors for SMOs during prenatal care. In addition, there should be a continuous audit of the indication and number of C-sections performed across health facilities.

The Relationship between Antenatal Care with Childbirth Complication in Indonesian’s Mothers (Data Analysis of The Indonesia Demographic and Health Survey 2012)

Labor complications often lead to maternal death. A good antenatal care can reduce maternal and infant mortality. The purpose of this study was to analyze the relationship between antenatal care and labor complication among Indonesian’s mothers. Data of the Indonesia Demographic and Health Survey (IDHS) 2012 from 33 Provinces were used in this study. Samples consisted of 11.803 women aged 15-49 years who delivered baby at sometimes during the last 5 years before survey. A cross-sectional design was used. Variables in the study consisted of dependent variable (labor complication), main independent variable (antenatal care) and potential confounder variables including maternal age in the last labor, mother’s education, number of parity, preceding birth interval, birth attendance, place of delivery, a history of pregnancy complications, history of previous labor complication and multiple pregnancies. A logistic regression was used for analyzing data. Results of this study showed that the prevalence of labor complications was 49.2% and the prevalence of poor antenatal cares (do not use a standard criteria recommended by Indonesian Health Ministry) was 91.2%. After controlling for all potential confounder variables, this study showed that, mothers with a poor antenatal care had a 1.3 times higher risk of labor complications than mothers with a good antenatal care (POR 1.3, 95% CI: 1.1 - 1.4).
