Abstract
BACKGROUND & AIMS Nutritional challenges following bariatric surgery can be intensified during pregnancy and may have crucial effects on the fetus, including lower birth weight. To the best of our knowledge, the effect of nutritional counseling during post-bariatric pregnancy to improve maternal diet quality and eating habits on neonatal outcome has not been evaluated. The aim of this research was to examine the effects of personal nutritional counseling during post-bariatric pregnancy on nutritional intake and neonatal outcomes. METHODS We performed a non-randomized, intervention-control clinical trial. Women (n = 61) were divided into three groups; two prospective, and one retrospective: 1. An Intervention Bariatric Prospective group 2. A Control Prospective group without surgery, and 3. A Control Bariatric Retrospective group. Patient enrollment was performed from April 2016 to March 2018. The intervention program included biweekly visits with a pregnancy nutrition certified bariatric dietitian. Data collection was performed four times during pregnancy, and included demographic and eating habits questionnaires, 24 h dietary recall, and information about delivery outcomes. In the retrospective group delivery outcomes and Food Frequency Questionnaire was collected once, after delivery. RESULTS There were no differences between groups at baseline except for a higher pre-pregnancy BMI in the post-bariatric groups. In the prospective groups, dietary protein, energy, and iron were found to be consumed in higher amounts in the Control-Prospective group than in the Intervention Bariatric-Prospective group (p < 0.05), without the addition of supplements. On the other hand, iron and calcium calculated from diet with supplements, were found to be significantly higher in the Intervention Bariatric Prospective group than in the Control Prospective group. In addition, consumption of saturated fats, oil, and salty snacks was lower in both prospective groups compared to the retrospective group (p < 0.05), suggesting better food quality habits for the bariatric group with nutritional counseling. Mean birth weight was significantly lower in the Control Bariatric Retrospective group than in the Control-Prospective group (3074 ± 368 g vs. 3396 ± 502 g, respectively. p = 0.023). In the Intervention Bariatric Prospective group, mean birth weight was 3168 ± 412 g, and no significant difference was observed from the Control Prospective group. Birth percentiles were also significantly lower in the Control Bariatric Retrospective group compared to the Control Prospective group (27th vs. 42nd, respectively. p < 0.05). In the Intervention Bariatric Prospective group, mean birth percentile was 35th, and no significant difference was observed from the Control Prospective group. As for the weight change of the woman during pregnancy, the highest variability was noted among the Control Bariatric Retrospective group with cases of weight loss up to 37 kg, due to conception close to the bariatric operation. Nevertheless, this variable was controlled, and showed no significant impact on birth weight results. CONCLUSIONS Our results suggest that personalized nutritional counseling care during post bariatric pregnancy improved nutrient intake of mothers and may contribute to higher birth weight of offspring. Further research is needed to examine the effects of prenatal nutrition care intervention, in addition to repeating this trial with a larger sample size, to allow for clearer findings.

Abstract
OBJECTIVE This study aimed to determine the feasibility and effectiveness of Diabetes Group Prenatal Care to increase patient engagement in diabetes self-care activities. STUDY DESIGN A pilot randomized controlled trial was conducted at two sites. Inclusion criteria were English or Spanish speaking, type 2 or gestational diabetes, 22 to 34 weeks of gestational age at first study visit, ability to attend group care at specified times, and willingness to be randomized. Exclusion criteria included type 1 diabetes, multiple gestation, major fetal anomaly, serious medical comorbidity, and serious psychiatric illness. Women were randomized to Diabetes Group Prenatal Care or individual prenatal care. The primary outcome was completion of diabetes self-care activities, including diet, exercise, blood sugar testing, and medication adherence. Secondary outcomes included antenatal care characteristics, and maternal, neonatal, and diabetes management outcomes. Analysis followed the intention-to-treat principle. RESULTS Of 159 eligible women, 84 (53%) consented to participate in the study and were randomized to group (n = 42) or individual (n = 42) prenatal care. Demographic characteristics were similar between study arms. Completion of diabetes self-care activities was similar overall, but women in group care ate the recommended amount of fruits and vegetables on more days per week (5.1 days/week ± 2.0 standard deviation [SD] in group care vs. 3.4 days ± 2.6 SD in individual care; p < 0.01) and gained less weight per week during the study period (0.2 lbs/week [interquartile range: 0-0.7] vs. 0.5 lbs/week [interquartile range: 0.2-0.9]; p = 0.03) than women in individual care. Women with gestational diabetes randomized to group care were 3.5 times more likely to have postpartum glucose tolerance testing than those in individual care (70 vs. 21%; relative risk: 3.5; 95% confidence interval: 1.4-8.8). Other maternal, neonatal, and pregnancy outcomes were similar between study arms. CONCLUSION Diabetes group care is feasible and shows promise for decreasing gestational weight gain, improving diet, and increasing postpartum diabetes testing among women with pregnancies complicated by diabetes. KEY POINTS · Women with gestational diabetes in group care were 3.5 times more likely to return for postpartum glucose tolerance testing.. · Women with gestational diabetes in group care had less gestational weight gain during the study period.. · Diabetes Group Prenatal Care is a promising intervention to improve outcomes for women with diabetes in pregnancy..

Abstract
Introduction: Offsprings from a prenatal docosahexaenoic acid (DHA) supplementation trial, in which pregnant women were assigned to placebo or 600mg DHA/day, were followed to determine the effect of prenatal DHA supplementation on the behavior and brain function at 5.5 years (n=81 placebo, n=86 supplemented).Methods: Event-related potentials (ERP) were recorded during a visual task requiring a button press (Go) to frequent target stimuli and response inhibition to the rare stimuli (No-Go). Univariate ANOVAs were used to test differences between group and sex for behavioral measures. ERP differences were tested using a three-way mixed-design multivariate analysis of variance (MANOVA).Results: There was a significant sex × group interaction for hit rate and errors of omission; there was no difference between males and females in the placebo group, but DHA males outperformed DHA females. Males overall and the placebo group made more errors requiring response inhibition; DHA females were significantly better than placebo females and DHA males. ERP P2 amplitude was larger in the DHA group. A significant N2 amplitude condition effect was observed in females and DHA group males, but not in placebo group males.Discussion: Prenatal DHA supplementation improved inhibitory performance overall, especially for females in the DHA group, possibly accounting for their conservative behavior during Go trials. Development of brain regions responsible for visual processing may be sensitive to maternal DHA status, evidenced by greater P2 amplitude. Males may benefit more from maternal DHA supplementation, indicated by the N2 condition effect seen only in males in the DHA group.

Abstract
This article summarises the Joint British Diabetes Societies for Inpatient Care guidelines on the management of glycaemia in pregnant women with diabetes on obstetric wards and delivery units, Joint British Diabetes Societies (JBDS) for Inpatient Care Group, ABCD (Diabetes Care) Ltd. The updated guideline offers two approaches - the traditional approach with tight glycaemic targets (4.0-7.0 mmol/L) and an updated pragmatic approach (5.0-8.0 mmol/L) to reduce the risk of maternal hypoglycaemia whilst maintaining safe glycaemia. This is particularly relevant for women with type 1 diabetes who are increasingly using Continuous Glucose Monitoring (CGM) and Continuous Subcutaneous Insulin Infusion (CSII) during pregnancy. All women with diabetes should have a documented delivery plan agreed during antenatal clinic appointments. Hyperglycaemia following steroid administration can be managed either by increasing basal and prandial insulin doses, typically by 50% to 80%, or by adding a variable rate of intravenous insulin infusion (VRIII). Glucose levels, either capillary blood glucose or CGM glucose levels, should be measured at least hourly from the onset of established labour, artificial rupture of membranes or admission for elective caesarean section. If intrapartum glucose levels are higher than 7.0 or 8.0 mmol/L on two consecutive occasions, VRIII is recommended. Hourly capillary blood glucose rather than CGM glucose measurements should be used to adjust VRIII. The recommended substrate fluid to be administered alongside a VRIII is 0.9% sodium chloride solution with 5% glucose and 0.15% potassium chloride (KCl) (20 mmol/L) or 0.3% KCl (40 mmol/L) at 50 ml/hr. Both the VRIII and CSII rates should be reduced by at least 50% after delivery.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is one of the most common complication of pregnancy that has significant impacts on both mother and her offspring health. The present study aimed to examine the effect of carbohydrate counting, carbohydrate counting combined with DASH, and control dietary interventions on glycemic control, and maternal and neonatal outcomes. METHODS A total of 75 pregnant women with GDM at 24th - 30th week of gestation were enrolled and randomized to follow one of the three diets: control or carbohydrate counting, or carbohydrate counting combined with Dietary Approach to Stop Hypertension (DASH). Only 70 of them completed the study until delivery. Fasting blood samples were taken at baseline and the end of the study to measure fasting blood glucose (FBG), fasting insulin, glycated hemoglobin (HbA1c), and fructosamine. Homeostatic model assessment-insulin resistance (HOMA-IR) score was calculated using HOMA2 calculator program. The participants recorded at least four blood glucose readings per day. Maternal and neonatal outcomes were collected from medical records. Dietary intake was assessed by three-day food records at the baseline and the end of the study. RESULTS Adherence to the three dietary interventions, resulted in decreased FBG levels significantly among all the participants (P < 0.05). Consumption of the carbohydrate counting combined with the DASH diet showed significant reduction in serum insulin levels and HOMA-IR score compared to carbohydrate counting group and control group. Means of fructosamine and HbA1c did not differ significantly among the three intervention diet groups. Overall mean of 1-h postprandial glucose (1 h PG) level was significantly lower in the carbohydrate counting combined with DASH group compared with that in the carbohydrate counting group and the control group (P < 0.001). The number of women who were required to commence insulin therapy after dietary intervention was significantly lower in carbohydrate counting group and carbohydrate counting combined with DASH group (P = 0.026). There were no significant differences in other maternal and neonatal outcomes among the three dietary intervention groups. CONCLUSIONS The carbohydrate counting and the carbohydrate counting combined with DASH dietary interventions resulted in beneficial effects on FBG and 1 h PG compared with the control diet. The three dietary interventions produced similar maternal and neonatal outcomes in women with GDM.

Comparative effectiveness of adjunct non-pharmacological interventions on maternal and neonatal outcomes in gestational diabetes mellitus patients: A systematic review and network meta-analysis protocol of randomized controlled trials.
Saha, S
PloS one. 2022;(1):e0263336
Abstract
BACKGROUND Gestational diabetes mellitus (GDM) in pregnancy leads to a range of perinatal complications. Although several randomized controlled trials (RCT) have tested the effect of non-pharmacological standard GDM care adjuncts on these outcomes, there is no agglomerated statistical evidence on how their occurrence risk varies across interventions and with placebo. Therefore, a systematic review and network meta-analysis (NMA) protocol is proposed here to address this evidence gap. MATERIALS AND METHODS A search for above RCTs published in the English language will transpire in PubMed, Embase, and Scopus databases irrespective of date and geographic boundary. The RCTs must test nutritional supplementation, digital intervention, structured exercise program, educational program, counseling service, or a combination of these prenatally in GDM patients. These should report ≥1 of the following outcomes- cesarean section, pre-eclampsia, polyhydramnios, preterm birth, macrosomia, prolonged labor, gestational hypertension, premature rupture of membranes, congenital anomaly, Apgar scores, birth weight, birth length, gestational age at birth, neonatal hypoglycemia, neonatal hyperbilirubinemia, and neonatal Corpulence Index. The risk of bias assessment of the recruited trials will transpire using the Revised Cochrane risk-of-bias tool. Determination of the comparative effectiveness between interventions will occur by the frequentist method NMA for respective outcomes. The categorical and continuous outcomes effect size will get calculated in risk ratio and weighted or standardized mean difference, respectively. For each NMA model, network maps and league tables will show the connections between interventions and effect sizes with their 95% confidence intervals for each intervention pair compared, respectively. The publication bias assessment will occur using comparison-adjusted funnel plots. Best intervention prediction for NMA models with statistically significant intervention effect will happen by determining the surface under the cumulative ranking curve values. Statistical analysis will ensue using Stata software (v16). The statistical significance estimation will happen at p<0.05 and 95% confidence interval.

EFFECTS OF VITAMIN D SUPPLEMENTATION DURING PREGNANCY ON NEWBORNS AND INFANTS: AN INTEGRATIVE REVIEW.
Dutra, LV, Souza, FIS, Konstantyner, T
Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo. 2021;:e2020087
Abstract
OBJECTIVE To identify the effects of vitamin D supplementation during pregnancy on newborns and infants. DATA SOURCES The present study is an integrative review of literature based on clinical trials published in journals indexed in the PubMed and Web of Science databases. Two searches were carried out, starting with the association (and) of the health term "vitamin D" with "pregnancy". In the search for information, selection criteria were established, and there was no language limitation and year of publication. DATA SYNTHESIS The final selection resulted in 44 clinical trials, most of which were randomized and double blind, which were carried out in outpatient clinics, referral hospitals and universities, mainly in Europe. The samples studied were predominantly of newborns. In these 44 trials, 23 types of different doses of vitamin D during pregnancy, with different doses, regimens and times of use, and 14 different outcomes were studied in newborns (NB) and infants. Of the 44 studies performed, 35 showed statistically significant beneficial effects of vitamin D supplementation during pregnancy on newborns and infants compared to control groups. CONCLUSIONS Vitamin D supplementation during pregnancy for at least three months before delivery has the potential of positively influencing calcium metabolism, physical growth and immune system development in newborns and infants. However, there is insufficient knowledge to define the optimal dose and to guarantee the absence of possible long-term adverse effects.

Abstract
OBJECTIVE To develop a core outcome set (COS) for randomised controlled trials (RCTs) evaluating the effectiveness of interventions for the treatment of pregnant women with pregestational diabetes mellitus (PGDM). DESIGN A consensus developmental study. SETTING International. POPULATION Two hundred and five stakeholders completed the first round. METHODS The study consisted of three components. (1) A systematic review of the literature to produce a list of outcomes reported in RCTs assessing the effectiveness of interventions for the treatment of pregnant women with PGDM. (2) A three-round, online eDelphi survey to prioritise these outcomes by international stakeholders (including healthcare professionals, researchers and women with PGDM). (3) A consensus meeting where stakeholders from each group decided on the final COS. MAIN OUTCOME MEASURES All outcomes were extracted from the literature. RESULTS We extracted 131 unique outcomes from 67 records meeting the full inclusion criteria. Of the 205 stakeholders who completed the first round, 174/205 (85%) and 165/174 (95%) completed rounds 2 and 3, respectively. Participants at the subsequent consensus meeting chose 19 outcomes for inclusion into the COS: trimester-specific haemoglobin A1c, maternal weight gain during pregnancy, severe maternal hypoglycaemia, diabetic ketoacidosis, miscarriage, pregnancy-induced hypertension, pre-eclampsia, maternal death, birthweight, large for gestational age, small for gestational age, gestational age at birth, preterm birth, mode of birth, shoulder dystocia, neonatal hypoglycaemia, congenital malformations, stillbirth and neonatal death. CONCLUSIONS This COS will enable better comparison between RCTs to produce robust evidence synthesis, improve trial reporting and optimise research efficiency in studies assessing treatment of pregnant women with PGDM. TWEETABLE ABSTRACT 165 key stakeholders have developed #Treatment #CoreOutcomes in pregnant women with #diabetes existing before pregnancy.

Nutrients. 2021;(4)
Abstract
Lifestyle interventions during pregnancy were shown to beneficially influence maternal dietary behaviour and physical activity, but their effect on health behaviour after delivery is unclear. The objective of this secondary analysis was to investigate the sustained effect of a lifestyle intervention in routine care on maternal health behaviour during the first year postpartum. The cluster-randomised controlled "Healthy living in pregnancy" (GeliS) study included 2286 pregnant women. Data on maternal health behaviour were collected at 6-8 weeks (T1pp) and one year postpartum (T2pp) using validated questionnaires. The intervention group showed a lower mean intake of fast food (T1pp: p = 0.016; T2pp: p < 0.001) and soft drinks (T1pp: p < 0.001), a higher mean intake of vegetables (T2pp: p = 0.015) and was more likely to use healthy oils for meal preparation than the control group. Dietary quality rated by a healthy eating index was higher in the intervention group (T1pp: p = 0.093; T2pp: p = 0.043). There were minor trends towards an intervention effect on physical activity behaviour. The proportion of smokers was lower in the intervention group (p < 0.001, both time points). The lifestyle intervention within routine care modestly improved maternal postpartum dietary and smoking behaviours.

Abstract
BACKGROUND Lifestyle interventions in pregnancy may influence postpartum development and obesity risk in offspring. The impact of lifestyle interventions as health system-based approaches is unclear. OBJECTIVE To evaluate the effect of an antenatal lifestyle intervention conducted as public health approach on infant development and feeding practices. METHODS We followed offspring born to women participating in the cluster-randomised GeliS trial who received usual care (CG) or repeated lifestyle counselling (IG). We collected data on offspring development and complementary feeding until the 12th month postpartum. RESULTS Of the 1998 mother-child pairs, 1783 completed the follow-up. Mean infant weight at 12 months was comparable between groups (IG: 9497.9 ± 1137.0 g; CG: 9433.4 ± 1055.2 g; P = .177). There was no significant evidence of differences in sex- and age-adjusted z-scores or in the odds of offspring being overweight. More infants in the IG received whole-grain products compared to the CG (95.6% vs. 90.8%; P = .003). Despite small differences in the timing of introducing solid foods, there were no further significant differences in the pattern of complementary feeding. CONCLUSIONS The antenatal lifestyle intervention embedded in routine care did not substantially influence infant anthropometrics and is thus unlikely to impact future development.
