Moreover, several studies have demonstrated the association between microRNAs (miRNAs) and FLD, in which miR-122, miR-34a and miR-192 were recognized as the most relevant miRNAs as biomarkers for FLD. We did not find any studies examining histone modifications in relation to FLD.

Cumulative evidence suggests a link between epigenetic mechanisms, specifically DNA methylation and miRNAs, and FLD. Further efforts should investigate the molecular pathways by which these epigenetic markers may regulate FLD and also the potential role of histone modifications in FLD.

To examine the associations between risk of pre-eclampsia and pregnancy levels of maternal 25-hydroxyvitamin D (25[OH]D) and oxidative stress biomarkers.

A nested case-control study (n=99; 34 cases; 65 controls) within a prospective pregnancy cohort. Maternal 25(OH)D and oxidative stress markers (six isomers of F

-isoprostanes; F

-isoPs) were measured in plasma at 12-18 and 24-26 gestational weeks. Vitamin D deficiency was defined as 25[OH]D less than 50nmol/L.

Maternal vitamin D deficiency was associated with increased 8-iso-PGF

(P=0.037), 15(R)-PGF

(P=0.004), (±)5-iPF

-VI (P=0.026) at 12-18weeks. Vitamin D deficiency was inversely associated with 8-iso-PGF

(P=0.019) and (±)5-iPF

-VI isomer (P=0.010) at 24-26weeks. Both maternal vitamin D deficiency (adjusted odds ratio [aOR], 4.79; 95% confidence interval [CI], 1.67-13.75) and increased (±)5-iPF

-VI (aOR, 2.46; 95% CI, 1.16-5.22) at 24-26weeks were associated with risk of pre-eclampsia. However, the interaction test between 25(OH)D and (±)5-iPF

-VI was not significant (P=0.143).

Plasma 25(OH)D below 50nmol/L was associated with increased oxidative stress levels during pregnancy as measured by two F

-isoP isomers, including the well-studied marker 8-iso-PGF

. Whether vitamin D-induced oxidative stress mediates the risk of pre-eclampsia warrants future study.

Plasma 25(OH)D below 50 nmol/L was associated with increased oxidative stress levels during pregnancy as measured by two F2 -isoP isomers, including the well-studied marker 8-iso-PGF2α . Whether vitamin D-induced oxidative stress mediates the risk of pre-eclampsia warrants future study.Mothers and fathers are at elevated risk for developing depression during the first postnatal year, especially among families from marginalized communities. Although a number of studies demonstrate that exposure to maternal depressive symptoms can undermine infants' regulatory development, less is known about the extent to which paternal depressive symptoms may also contribute. The current study investigated whether maternal and paternal depressive symptoms were uniquely associated with infants' physiological regulation, and whether associations varied depending on infant sex. Participants included 90 low-income Mexican American families. Fathers and mothers self-reported their depressive symptoms when infants were 15 weeks old, and infants' resting parasympathetic activity (i.e., respiratory sinus arrhythmia [RSA]) was assessed at 6 and 24 weeks. Results indicated that, after controlling for infant 6-week RSA and depressive symptoms in the other parent, paternal depressive symptoms were associated with lower 24-week RSA for both girls and boys, but maternal depressive symptoms were only associated with lower 24-week RSA for boys. Findings highlight a potential mechanism through which the consequences of parent depressive symptoms may reverberate across generations, and suggest that considerations of both infants' and parents' sex may lend insight into how best to intervene.

We aimed to analyse the pre-analytical process and its effect of 50g of oral glucose challenge test results for screening gestational diabetes mellitus.

The 50g oral glucose challenge test was performed to 30 pregnant women, and the blood was collected as two samples for three tubes containing; serum separating jell (SSJ), sodium fluoride-potassium oxalate (NaF - KOx) and sodium citrate-containing tube. The first samples of the three tubes were centrifuged within 30minutes, and second samples were centrifuged after 60minutes and were analysed. One sample in SSJ tube and was analysed in the same day according to hospitals routine practice. The results were compared.

Among the 30 samples, the mean decrease in glucose levels was highest in the SSJ tube (0.38mmol/L), followed by 0.16mmol/L in Na citrate tube and 0.14mmol/L in NaF-KOx tube. The hospital routine assessment with SSJ was 6.36±1.90mmol/L. The <30 and >60minutes glucose results were 6.80±1.88mmol/L vs 6.42±1.97mmol/L for SSJ, 5.95±1.60mmol/L vs 5.78±1.51mmol/L for Na Citrate and 6.90±1.86mmol/L vs 6.75±1.90mmol/L for NaF-KOx mg/dL groups, respectively, and both the changes within time and the results between the tubes showed a statistically significant difference (P<.001).

In cases with longer assessment time and with different blood sample tubes, the clinician should also keep in mind that, especially with results under but close to the cut-off levels, an underdiagnosed gestational diabetes might be present.

However, other programming windows have been recognized in the last years, namely lactation, infancy, adolescence and even preconception. Although the concept has been developed in order to study the impact of foetal calorie restriction in adult life, it is now recognized that maternal overweight during programming windows is also harmful to the offspring. This article explores and summarizes the current knowledge about the impact of maternal obesity and obesogenic diets during lactation in the metabolic programming towards the development of metabolic syndrome in the adult life. The impact of maternal obesity and obesogenic diets in milk quality is discussed, including the alterations in specific micro and macronutrients, as well as the impact of such alterations in the development of metabolic syndrome-associated features in the newborn, such as insulin resistance and adiposity. Moreover, the impact of milk quality and formula feeding in infants' gut microbiota, immune system maturation and in the nutrient-sensing mechanisms, namely those related to gut hormones and leptin, are also discussed under the current knowledge.This study examined how intergroup processes and social-cognitive factors shape bystander responses to bias-based and general bullying. Participants included sixth and ninth graders (N = 179, M = 13.23) who evaluated how likely they would be to intervene if they observed bullying of immigrant-origin and nonimmigrant-origin peers. Adolescents' grade, intergroup attitudes, and social-cognitive abilities were evaluated as predictors of bystander responses. Nonimmigrant-origin adolescents reported that they expect they would be less likely to intervene when the victim is an immigrant-origin peer. Furthermore, participants with more intergroup contact and higher theory of mind were more likely to expect they would intervene in response to bias-based bullying. Findings have important implications for understanding factors that inform antibullying interventions that aim to tackle bias-based bullying against immigrants.Red blood cell distribution width (RDW), which generally increases with age, is a risk marker for morbidity and mortality in various diseases. We investigated the association between elevated RDW and prior radiation exposure by examining longitudinal RDW changes in 4204 atomic-bomb survivors over 15 years. A positive association was found between RDW and radiation dose, wherein RDW increased by 0·18%/Gy. This radiation-associated effect increased as the participants aged. Elevated RDW was also associated with higher all-cause mortality. The biological mechanisms underlying these observed associations merit further investigation.

Since the WOMAN trial, intravenous tranexamic acid (TXA) has been increasingly used in severe postpartum haemorrhage (PPH) but research evaluating use in high-income settings is limited.

To assess whether implementation of a new guideline involving early administration of 1 g intravenous TXA in active PPH with blood loss ≥1000 mL, was associated with a change in maternal morbidity.

Retrospective study of all singleton, term, vaginal births from November 2016 to June 2019 with a PPH of ≥1000 mL, before and after hospital adoption of a guideline recommending early (within three hours of birth) administration of TXA for women with active PPH ≥1000 mL. Univariate analysis assessed the impact of this guideline implementation on a primary outcome of maternal morbidity, defined as one or more of haemoglobin <90g/L, administration of blood products, hysterectomy or intensive care admission. Secondary outcomes were adverse events related to administration of TXA, use of an intrauterine balloon or postpartum iron infusion.

There was no difference in morbidity (odds ratio (OR) 0.86, 95% CI 0.57-1.29, P=0.46) or postpartum iron infusion (OR 1.44, 95% CI 0.92-2.27, P=0.11), but there was a reduction in the use of intrauterine balloon tamponade after the implementation of the TXA guideline (OR 0.33, 95% CI 0.16-0.67, P<0.01).

This retrospective analysis showed a reduced use of intrauterine balloon but failed to show a benefit in maternal morbidity with early administration of TXA for severe postpartum haemorrhage in a high-income setting.

Indigenous women in the high-income countries of Canada, Australia, New Zealand and USA, have a higher incidence and mortality from cervical cancer than non-Indigenous women. Increasing cervical screening coverage could ultimately decrease cervical cancer disparities.

To increase cervical screening for under-screened/never-screened Māori women.

This study was a cluster randomised controlled trial. Inclusion criteria were women aged 25-69, last screened ≥4years ago, in Northland, New Zealand. The intervention arm was the offer of a human papilloma virus (HPV) self-test and the control arm was the usual offer of standard care - a cervical smear. PYR-41 research buy The primary outcome was rate of cervical screening in the intervention group compared to control in Māori, the Indigenous peoples of New Zealand. Six primary care clinics were randomly allocated to intervention or control.

Of 500 eligible Māori women in the intervention arm, 295 (59.0%) were screened. Of 431 eligible Māori women in the control arm, 94 (21.8%) were screened.
