Pradella F, Witte P, van Ewijk R. Ramadan during pregnancy and offspring health outcomes over the life course: a systematic review and meta-analysis. Hum Reprod Update 2024:dmae026.

Abstract
BACKGROUND Intermittent fasting, such as during Ramadan, is prevalent among pregnant women. However, the association between Ramadan during pregnancy and offspring health along the life course has not been fully established. OBJECTIVE AND RATIONALE Fetal programming research indicates that prenatal exposures, particularly during early pregnancy, can cause long-term structural and physiological changes that adversely affect offspring health. Our objective was to systematically identify and assess the evidence regarding Ramadan during pregnancy. SEARCH METHODS A total of 31 studies were sourced from PubMed, EMBASE, Web of Science, and EconLit. Included studies evaluated outcomes in individuals with prenatal Ramadan exposure, compared to unexposed Muslim controls. Main outcomes were birth weight, gestational length, and sex ratio in newborns; height, mortality, and cognition in children; and disabilities, chronic diseases, and human capital accumulation in adults. Each study was evaluated for risk of bias. The overall quality of evidence was appraised using the GRADE system. Random-effects meta-analyses were conducted for outcomes analyzed in at least three primary studies. OUTCOMES The initial search identified 2933 articles, 1208 duplicates were deleted. There were 31 publications fulfilled the eligibility criteria for the qualitative synthesis; 22 studies were included in meta-analyses. The overall quality of the evidence was low to moderate and differed by study design and outcome. Among newborns, prenatal Ramadan exposure was not associated with birth weight (mean difference (MD) -3 g (95% CI -18 to 11; I2 = 70%) or the likelihood of prematurity (percentage point difference (PPD) 0.19 (95% CI -0.11 to 0.49; I2 = 0%)). The probability that the newborn is male was reduced (PPD -0.14 (95% CI -0.28 to -0.00; I2 = 0%)). This potentially reflects sex-specific mortality rates resulting from adverse in utero circumstances. In childhood, the exposed performed slightly poorer on cognitive tests (MD -3.10% of a standard deviation (95% CI -4.61 to -1.58; I2 = 51%)). Height among the exposed was reduced, and this pattern was already visible at ages below 5 years (height-for-age z-score MD -0.03 (95% CI -0.06 to -0.00; I2 = 76%)). A qualitative literature synthesis revealed that childhood mortality rates were increased in low-income contexts. In adulthood, the prenatally exposed had an increased likelihood of hearing disabilities (odds ratio 1.26 (95% CI 1.09 to 1.45; I2 = 32%)), while sight was not affected. Other impaired outcomes included chronic diseases or their symptoms, and indicators of human capital accumulation such as home ownership (qualitative literature synthesis). The first trimester emerged as a sensitive period for long-term impacts. WIDER IMPLICATIONS Despite the need for more high-quality studies to improve the certainty of the evidence, the synthesis of existing research demonstrates that Ramadan during pregnancy is associated with adverse offspring health effects in childhood and especially adulthood, despite an absence of observable effects at birth. Not all health effects may apply to all Muslim communities, which are diverse in backgrounds and behaviors. Notably, moderating factors like daytime activity levels and dietary habits outside fasting hours have hardly been considered. It is imperative for future research to address these aspects.

Abstract
Dietary nutrition plays a crucial role in determining pregnancy outcomes, with poor diet being a major contributor to pregnancy metabolic syndrome and metabolic disorders in offspring. While carbohydrates are essential for fetal development, the excessive consumption of low-quality carbohydrates can increase the risk of pregnancy complications and have lasting negative effects on offspring development. Recent studies not only highlighted the link between carbohydrate intake during pregnancy, maternal health, and offspring well-being, but also suggested that the quality of carbohydrate foods consumed is more critical. This article reviews the impacts of low-carbohydrate and high-carbohydrate diets on pregnancy complications and offspring health, introduces the varied physiological effects of different types of carbohydrate consumption during pregnancy, and emphasizes the importance of both the quantity and quality of carbohydrates in nutritional interventions during pregnancy. These findings may offer valuable insights for guiding dietary interventions during pregnancy and shaping the future development of carbohydrate-rich foods.

Abstract
OBJECTIVE Delta-like homolog 1 (DLK1) is a growth factor that is reduced in maternal sera in pregnancies with small for gestational age neonates. We sought to determine if DLK1 is associated with stillbirth (SB), with and without placental insufficiency. STUDY DESIGN A nested case-control study was performed using maternal sera from a multicenter case-control study of SB and live birth (LB). SB and LB were stratified as placental insufficiency cases (small for gestational age <5% or circulatory lesions on placental histopathology) or normal placenta controls (appropriate for gestational age and no circulatory lesions). Enzyme-linked immunosorbent assay (ELISA) was used to measure DLK1. The mean difference in DLK1 was compared on the log scale in an adjusted linear regression model with pairwise differences, stratified by term/preterm deliveries among DLK1 results in the quantifiable range. In exploratory analysis, geometric means were compared among all data and the proportion of "low DLK1" (less than the median value for gestational age) was compared between groups and modeled using linear and logistic regression, respectively. RESULTS Overall, 234 SB and 234 LB were analyzed; 246 DLK1 values were quantifiable within the standard curve. Pairwise comparisons of case and control DLK1 geometric means showed no significant differences between groups. In exploratory analysis of all data, adjusted analysis revealed a significant difference for the LB comparison only (SB: 71.9 vs. 99.1 pg/mL, p = 0.097; LB: 37.6 vs. 98.1 pg/mL, p = 0.005). In exploratory analysis of "low DLK1," there was a significant difference between the odds ratio of having "low DLK1" between preterm cases and controls for both SB and LB. There were no significant differences in geometric means nor "low DLK1" between SB and LB. CONCLUSION In exploratory analysis, more placental insufficiency cases in preterm SB and LB had "low DLK1." However, low DLK1 levels were not associated with SB. KEY POINTS · Maternally circulating DLK1 is correlated with placental insufficiency.. · Maternally circulating DLK1 is not correlated with SB.. · DLK1 is a promising marker for placental insufficiency..

Abstract
AIMS/HYPOTHESIS Pregnant women are advised to consume a minimum of 175 g per day of carbohydrate to meet maternal and fetal brain glucose requirements. This recommendation comes from a theoretical calculation of carbohydrate requirements in pregnancy, rather than from clinical data. This study aimed to determine whether fasting maternal ketone levels are associated with habitual carbohydrate intake in a subset of participants of the Study of PRobiotics IN Gestational diabetes (SPRING) randomised controlled trial. METHODS Food frequency questionnaires on dietary intake during pregnancy were completed by pregnant women with overweight or obesity at 28 weeks' gestation (considering their intake from the beginning of pregnancy). Dietary intake from early pregnancy through to 28 weeks was analysed for macronutrient intake. At the same time, overnight fasting serum samples were obtained and analysed for metabolic parameters including serum β-hydroxybutyrate, OGTTs, insulin and C-peptide. RESULTS Fasting serum β-hydroxybutyrate levels amongst 108 women (mean BMI 34.7 ± 6.3 kg/m2) ranged from 22.2 to 296.5 μmol/l. Median fasting β-hydroxybutyrate levels were not different between women with high (median [IQR] 68.4 [49.1-109.2 μmol/l]) and low (65.4 [43.6-138.0 μmol/l]) carbohydrate intake in pregnancy. Fasting β-hydroxybutyrate levels were not correlated with habitual carbohydrate intake (median 155 [126-189] g/day). The only metabolic parameter with which fasting β-hydroxybutyrate levels were correlated was 1 h venous plasma glucose (ρ=0.23, p=0.03) during a 75 g OGTT. CONCLUSIONS/INTERPRETATION Fasting serum β-hydroxybutyrate levels are not associated with habitual carbohydrate intake at 28 weeks' gestation in pregnant women with overweight and obesity.

Abstract
Euglycemic diabetic ketoacidosis (EDKA) is an emerging complication of diabetes associated with an increasing use of sodium-glucose transporter type 2 (SGLT-2) inhibitor drugs. This review highlights the growing incidence of EDKA and its diagnostic challenges due to the absence of hallmark hyperglycemia seen in diabetic ketoacidosis (DKA). The paper presents a classification system for the severity of EDKA, categorizing it into mild, moderate, and severe based on serum pH and bicarbonate levels. Another classification system is proposed to define stages of EDKA based on anion gap and ketones at the time of diagnosis and during the treatment period. A treatment algorithm is proposed to guide clinicians in managing EDKA. This treatment algorithm includes monitoring anion gap and ketones to guide insulin and fluid management, and slower transition to subcutaneous insulin to prevent a relapse. Increased awareness of EDKA is essential for a timely diagnosis because an early diagnosis and treatment can improve clinical outcomes.

Abstract
Background/Objective Diabetic ketoacidosis (DKA) during pregnancy is an obstetric emergency associated with a higher rate of maternofetal morbidity and mortality. Pregnancy itself is a ketosis-prone state and several unique mechanisms predispose to the development of insulin resistance, which can be further exacerbated by acute stressors such as infection. Thus, pregnant patients who additionally contract COVID-19 may be at an even higher risk of development of DKA. Case Report A 32-year-old patient, with no prior history of impaired glucose tolerance, presented at 27 weeks of gestation with a 3-day history of shortness of breath, congestion, loss of taste and smell, polyuria, and polydipsia. Biochemical evaluation was consistent with DKA. Subsequently, she was diagnosed with acute SARS-CoV-2 infection. Treatment included intravenous hydration, electrolyte replacement, and insulin infusion. Postpartum phenotypic evaluation confirmed autoimmune diabetes (positive GAD-65 and zinc T8 antibodies) with residual β-cell function. Six months postpartum, glycemic control remains at goal with basal- bolus insulin regimen. Discussion This case describes the peculiar ability of SARS-CoV-2 infection to potentially rouse autoimmunity and how COVID-19 and DKA in pregnancy can be particularly challenging given the risk of significant maternal and fetal morbidity and mortality. Conclusion Prompt diagnosis and evaluation of DKA in pregnancy as well as a higher level of suspicion is needed in the setting of SARS-CoV-2 infection. Additionally, this case depicts the need for closely monitoring the postpartum period for patients at risk of autoimmune disease, which may have been blunted in pregnancy.

Ramadan during pregnancy and neonatal health-Fasting, dietary composition and sleep patterns. PLoS One 2023; 18:e0281051.

Abstract
BACKGROUND AND OBJECTIVES Large shares of pregnant Muslims worldwide observe the Ramadan fast. Previous research showed that Ramadan during pregnancy is associated with adverse offspring health outcomes lasting throughout the life-course. Evidence on effects on birth outcomes is inconclusive, however, and previous research did not consider the role of dietary composition and sleep patterns during Ramadan. This study systematically documents maternal lifestyle during Ramadan and assesses if diet and sleep adaptations to Ramadan, independent of and in addition to maternal fasting, are associated with neonatal health outcomes. METHODS This study reports a survey of 326 Muslims who delivered their baby in Mainz, Germany, linked to maternal & infant hospital records. Participants reported on fasting, dietary composition and sleep schedules while pregnant during Ramadan. RESULTS Fasting during pregnancy was associated with reduced birthweight, in particular for fasting during the first trimester (-352ˑ92g, 95% CI: -537ˑ38; -168ˑ46). Neither dietary composition nor altered sleep were directly associated with birthweight. However, dietary composition during Ramadan outside of fasting hours seems to moderate the fasting-birthweight association, which disappeared for women switching to high-fat diets. CONCLUSIONS The finding that dietary intake during Ramadan potentially moderates the fasting-birthweight association is of high relevance to pregnant Muslims who wish to fast and their healthcare professionals, since dietary choices outside of fasting hours are often relatively easily modifiable. This is the first study to include information on maternal diet and sleep during Ramadan, and additional research is needed to assess the roles of specific (macro)nutrients and food groups.

Abstract
CONTEXT Diabetic ketoacidosis (DKA) in pregnancy is an obstetric emergency with risk of maternofetal death. OBJECTIVE This work aimed to evaluate DKA events in pregnant women admitted to our inpatient obstetric service, and to examine associated clinical risk factors, presentation, and pregnancy outcomes. METHODS A retrospective cohort study was conducted at the Mayo Clinic, Rochester, Minnesota, USA, and included women aged 17 to 45 years who were treated for DKA during pregnancy between January 1, 2004 and December 31, 2021. Main outcome measures included maternal and fetal death along with a broad spectrum of maternal and fetal pregnancy outcomes. RESULTS A total of 71 DKA events were identified in 58 pregnancies among 51 women, 48 (82.8%) of whom had type 1 diabetes. There were no maternal deaths, but fetal demise occurred in 10 (17.2%) pregnancies (6 miscarriages and 4 stillbirths). Maternal social stressors were frequently present (n = 30, 51.0%), and glycemic control was suboptimal (median first trimester glycated hemoglobin A1c = 9.0%). Preeclampsia was diagnosed in 17 (29.3%) pregnancies. Infants born to women with DKA were large for gestational age (n = 16, 33.3%), suffered from neonatal hypoglycemia (n = 29, 60.4%) and required intensive care unit admission (n = 25, 52.1%). CONCLUSION DKA is associated with a high rate of maternofetal morbidity and fetal loss. Prenatal education strategies for women with diabetes mellitus should include a strong focus on DKA prevention, and clinicians and patients should have a high index of suspicion for DKA in all pregnant women who present with symptoms that could be attributed to this condition.

Abstract
Obesity in women of reproductive age is common. Emerging evidence suggests that maternal obesity not only increases the risk of adverse pregnancy outcomes but also has an enduring impact on the metabolic health of the offspring. Given this, management of obesity prior to pregnancy is critically important. Almost all international guidelines suggest that women with obesity should aim to achieve weight loss prior to pregnancy. However, current pre-conception weight loss therapies are sub-optimal. Lifestyle modification typically results in modest weight loss. This may assist fertility but does not alter pregnancy outcomes. Bariatric surgery results in substantial weight loss, which improves pregnancy outcomes for the mother but may be harmful to the offspring. Alternative approaches to the management of obesity in women planning pregnancy are needed. Very low energy diets (VLEDs) have been proposed as a possible tool to assist women with obesity achieve weight loss prior to conception. While VLEDs can induce substantial and rapid weight loss, there are concerns about the impact of rapid weight loss on maternal nutrition prior to pregnancy and about inadvertent exposure of the early fetus to ketosis. The purpose of this review is to examine the existing literature regarding the safety and efficacy of a preconception VLED program as a tool to achieve substantial weight loss in women with obesity.

Abstract
Studies of obstetric outcomes in women consuming low-carbohydrate diets have reported conflicting results. Most studies have defined low-carbohydrate diets by the percentage that carbohydrates contribute to overall energy intake, rather than by an absolute amount in grams per day (g/d). We hypothesised that a low absolute carbohydrate diet affects obstetric outcomes differently than a low percentage carbohydrate diet. Dietary data were collected from overweight or obese women in the Study of Probiotic IN Gestational diabetes at 16- and 28-weeks' gestation. Obstetric outcomes were compared between women whose carbohydrate intake was in the lowest quintile vs quintiles 2-5. Mean gestation was increased in women whose absolute carbohydrate intake was in the lowest quintile at 16 and at both 16- and 28-weeks' gestation compared with all other women (16: 39.7 vs. 39.1 weeks, p = 0.008; 16 and 28: 39.8 vs. 39.1, p = 0.005). In linear regression analysis, a low absolute carbohydrate intake at 16 and at 28 weeks' gestation was associated with increased gestation at delivery (16: p = 0.04, adjusted R2 = 0.15, 28: p = 0.04, adjusted R2 = 0.17). The coefficient of beta at 16 weeks' gestation was 0.50 (95% CI 0.03-0.98) and at 28 weeks' gestation was 0.51 (95%CI 0.03-0.99) meaning that consumption of a low absolute carbohydrate diet accounted for an extra 3.5 days in gestational age. This finding was not seen in women whose percentage carbohydrate intake was in the lowest quintile. Low-carbohydrate consumption in pregnancy is associated with increased gestational age at delivery.

Abstract
BACKGROUND The remarkable ability of the body to adapt to long-term starvation has been critical for survival of primitive man. An appreciation of these processes can provide the clinician better insight into many clinical conditions characterized by ketoacidosis. SUMMARY The body adapts to long-term fasting by conserving nitrogen, as the brain increasingly utilizes keto acids, sparing the need for glucose. This shift in fuel utilization decreases the need for mobilization of amino acids from the muscle for purposes of gluconeogenesis. Loss of urinary nitrogen is initially in the form of urea when hepatic gluconeogenesis is dominant and later as ammonia reflecting increased glutamine uptake by the kidney. The carbon skeleton of glutamine is utilized for glucose production and regeneration of consumed HCO3-. The replacement of urea with NH4+ provides the osmoles needed for urine flow and waste product excretion. Over time, the urinary loss of nitrogen is minimized as kidney uptake of filtered ketone bodies becomes more complete. Adjustments in urine Na+ serve to minimize kidney K+ wasting and, along with changes in urine pH, minimize the likelihood of uric acid precipitation. There is a sexual dimorphism in response to starvation. Key Message: Ketoacidosis is a major feature of common clinical conditions to include diabetic ketoacidosis, alcoholic ketoacidosis, salicylate intoxication, SGLT2 inhibitor therapy, and calorie sufficient but carbohydrate-restricted diets. Familiarity with the pathophysiology and metabolic consequences of ketogenesis is critical, given the potential for the clinician to encounter one of these conditions.

Abstract
OBJECTIVES This study analyzes the intent-to-treat effect of prenatal exposure to Ramadan (the Islamic month of fasting) on outcomes including stunting and underweight for children under age 5 years in Pakistan born between 2003 and 2018. METHODS The study uses observational data from four rounds of the UN-supported Multiple Indicator Cluster Survey (MICS) data collected on 204,186 children under-5 from Punjab, Pakistan in 2007-2008, 2010-2011, 2013-2014, and 2017-2018. Excluding data on outliers and observations with incomplete data, multivariate logistic regression analysis was conducted on the appended cross-sectional data of 179,943 children under-5 to assess the risk of stunting or underweight according to the month of gestation coinciding with Ramadan. RESULTS We observe a significant increase in the risk of stunting and underweight associated with exposure to Ramadan following an inverted-U pattern. The peak impact of Ramadan exposure on a child being underweight occurs in the third month of pregnancy, where the probability of being underweight is 20 percent higher as compared to children whose gestation did not coincide with Ramadan. The peak impact of Ramadan exposure on stunting occurs in the fourth month of pregnancy, where the probability of stunting is 22 percent higher as compared to children whose gestation did not coincide with Ramadan. These results vary little by gender. In contrast, exposure to Ramadan in the ninth month of gestation is associated with a reduction in the risk of stunting for boys and underweight for both boys and girls. CONCLUSIONS FOR PRACTICE Our analysis indicates that prenatal exposure to Ramadan during the first two trimesters have negative implications for children's growth. The study highlights the critical role of maternal habits during early pregnancy, especially nutritional intake, for the long-term physical development of children.

Abstract
We present a case of a metabolic acidosis in a term-pregnant woman with SARS-CoV-2 infection. Our patient presented with dyspnoea, tachypnoea, thoracic pain and a 2-day history of vomiting, initially attributed to COVID-19 pneumonia. Differential diagnosis was expanded when arterial blood gas showed a high anion gap metabolic non-lactate acidosis without hypoxaemia. Most likely, the hypermetabolic state of pregnancy, in combination with maternal starvation and increased metabolic demand due to infection, had resulted in metabolic ketoacidosis. Despite supportive treatment and rapid induction of labour, maternal deterioration and fetal distress during labour necessitated an emergency caesarean section. The patient delivered a healthy neonate. Postpartum, after initial improvement in metabolic acidosis, viral and bacterial pneumonia with subsequent significant respiratory compromise were successfully managed with oxygen supplementation and corticosteroids. This case illustrates how the metabolic demands of pregnancy can result in an uncommon presentation of COVID-19.

Abstract
During pregnancy, metabolic adaptations occur to maintain the balance between maternal and foetal growth, including increased insulin secretion and decreased insulin sensitivity. When the body fails to adjust, gestational diabetes mellitus develops. To gain insight in the pregnancy-induced adaptations, we applied continuous glucose monitoring via telemetric transmitters. We show that continuous glucose monitoring in conscious, non-stressed, freely moving mice throughout the full pregnancy is feasible, accurate and safe. We show that healthy mice during a full pregnancy develop adaptations in glucose homeostasis reminiscent of those in pregnant women. Furthermore, continuous glucose monitoring allows the complete analysis of all aspects of glucose excursions associated with spontaneous feeding episodes, and the thorough analysis of glycaemic variability. In conclusion, continuous glucose monitoring allows a detailed description of the glycaemic status during pregnancy, which will help to unravel specific mechanisms for gestational diabetes mellitus.

Abstract
Little is known about fasting practices and dietary changes during Ramadan in low‐ and lower‐middle‐income countries. Although pregnant women are exempt from fasting, they may still fast. This is of interest as dietary habits during pregnancy may affect the development of the unborn child. In a community‐based sample of young women in rural Sylhet division, Bangladesh, we described fasting practices and beliefs (n = 852). We also examined reported food group consumption and minimally adequate dietary diversity for women (MDD‐W) by Ramadan occurrence (n = 1,895) and by fasting adherence (n = 558) using logistic regression with Hindu women as a seasonal control. During Ramadan in 2018, 78% of pregnant Muslim women fasted every day. Over 80% of Muslim women believe that they should fast during pregnancy and over 50% expect positive health effects on the mother and the unborn child. We found strong evidence that Muslim women have more diverse diets during Ramadan, with higher odds of MDD‐W (OR [95% CI]: 5.0 [3.6, 6.9]) and increased consumption of pulses, dairy, fruit, and large fish. Dietary diversity increased to a lesser extent on non‐fasting days during Ramadan. Ramadan appears to improve dietary quality in both fasting and non‐fasting Muslim women in a rural population in Bangladesh. These results help to interpret findings from studies on Ramadan during pregnancy on later‐life outcomes and thus contribute to a better understanding of intrauterine influences of maternal nutrition on healthy child development.

Abstract
Current dietary advice for women with gestational diabetes mellitus is to avoid diets that result in elevated ketone levels. This guidance stems from a concern that maternal ketones are associated with poor fetal and childhood outcomes, including reduced childhood intelligence quota. The evidence behind these guidelines is conflicting and inconsistent. Given that dietary counseling is the initial treatment strategy for women with diabetes in pregnancy, it is important that clinicians understand the concern regarding maternal ketones. This review examines the physiology of ketogenesis in pregnancy, the prevalence of elevated maternal ketone levels, and the relationship between maternal ketones and fetal and childhood outcomes.

Abstract
Glycogen storage disease type 0 (GSD 0) is a rare inborn error of metabolism due to deficiency of the enzyme glycogen synthase (EC 2.4.1.11). The disorder is clinically characterized by ketotic fasting hypoglycemia in combination with postprandial hyperglycemia and hyperlactatemia. So far, only one pregnancy has been described in a woman with GSD 0. We report a 32-year-old GSD 0 patient with three successful pregnancies. The diagnosis of GSD 0 was made in early childhood due to characteristic symptoms. The patient had two healthy children at the time of her first visit in our metabolic center. The diet was optimized prior to her third pregnancy with a protein-rich diet including cornstarch and protein supplements. Pregnancy was confirmed at week 6 of gestation. Dietary management was difficult during pregnancy, especially in the first trimester due to severe nausea. Labor was induced at 37 weeks of gestation due to cholestasis of pregnancy, and the patient delivered a healthy baby girl. Perinatally, the mother received a high glucose infusion to stabilize blood glucose levels. The neonate also required a glucose infusion postnatally because of impaired glucose homeostasis. Similar to diabetic fetopathy, recurrent maternal hyperglycemia may result in hyperinsulinism of the child and trigger neonatal hypoglycemia. All four pregnancies in women with GSD 0 described to date occurred with minor complications and resulted in healthy offspring, which underpins the good prognosis and rather benign character of this rare metabolic disease. Careful monitoring during pregnancy and delivery is, however, necessary to minimize the risk of recurrent hypoglycemia for both mother and child.

Abstract
Pregnancy may be the most nutritionally sensitive stage in the life cycle, and improved metabolic health during gestation and early postnatal life can reduce the risk of chronic disease in adulthood. Successful pregnancy requires coordinated metabolic, hormonal, and immunological communication. In this review, maternal-fetal metabolic communication is defined as the bidirectional communication of nutritional status and metabolic demand by various modes including circulating metabolites, endocrine molecules, and other secreted factors. Emphasis is placed on metabolites as a means of maternal-fetal communication by synthesizing findings from studies in humans, non-human primates, domestic animals, rabbits, and rodents. In this review, fetal, placental, and maternal metabolic adaptations are discussed in turn. (1) Fetal macronutrient needs are summarized in terms of the physiological adaptations in place to ensure their proper allocation. (2) Placental metabolite transport and maternal physiological adaptations during gestation, including changes in energy budget, are also discussed. (3) Maternal nutrient limitation and metabolic disorders of pregnancy serve as case studies of the dynamic nature of maternal-fetal metabolic communication. The review concludes with a summary of recent research efforts to identify metabolites, endocrine molecules, and other secreted factors that mediate this communication, with particular emphasis on serum/plasma metabolomics in humans, non-human primates, and rodents. A better understanding of maternal-fetal metabolic communication in health and disease may reveal novel biomarkers and therapeutic targets for metabolic disorders of pregnancy.

Abstract
INTRODUCTION Women undergoing elective caesarean deliveries are fasted for long periods prior to surgery and can become catabolic. The use of pre-operative carbohydrate drinks to optimise patients ahead of major surgery is now well established. However, evidence to support this in women undergoing elective caesarean delivery is limited. METHODS We conducted a single-blind randomised control trial to study the effect of carbohydrate preloading on the presence of urinary ketones in mothers undergoing elective caesarean deliveries compared with standard care, fasting from midnight the night before surgery with free clear fluids until two hours prior to surgery. RESULTS Two-hundred-and-nine patients were allocated to either standard care (n=104) or pre-operative carbohydrate drinks (n=105) prior to elective caesarean section. Twenty-five were excluded from the analysis, leaving 184 (n=90; n=94). The incidence of urinary ketones immediately prior to surgery was lower in the carbohydrate group, 18.1% compared with 61.1% in the standard care group (P<0.001). Relative risk (95% CI) 3.33 (2.12 to 5.26), with a number needed-to-treat of three to prevent urinary ketosis in one woman. There were no major adverse events. CONCLUSION The results of this study support the introduction of carbohydrate drinks ahead of caesarean delivery to offset the effects of pre-operative fasting. However, the results may not be generalisable to all maternity units due to differences in fasting protocols.

Abstract
BACKGROUND Lower carbohydrate diets have the potential to improve glycemia but may increase ketonemia in women with gestational diabetes (GDM). We hypothesized that modestly lower carbohydrate intake would not increase ketonemia. OBJECTIVE To compare blood ketone concentration, risk of ketonemia, and pregnancy outcomes in women with GDM randomly assigned to a lower carbohydrate diet or routine care. METHODS Forty-six women aged (mean ± SEM) 33.3 ± 0.6 y and prepregnancy BMI 26.8 ± 0.9 kg/m2 were randomly assigned at 28.5 ± 0.4 wk to a modestly lower carbohydrate diet (MLC, ∼135 g/d carbohydrate) or routine care (RC, ∼200 g/d) for 6 wk. Blood ketones were ascertained by finger prick test strips and 3-d food diaries were collected at baseline and end of the intervention. RESULTS There were no detectable differences in blood ketones between completers in the MLC group compared with the RC group (0.1 ± 0.0 compared with 0.1 ± 0.0 mmol/L, n = 33, P = 0.31, respectively), even though carbohydrate and total energy intake were significantly lower in the intervention group (carbohydrate 165 ± 7 compared with 190 ± 9 g, P = 0.04; energy 7040 ± 240 compared with 8230 ± 320 kJ, P <0.01, respectively). Only 20% of participants in the MLC group met the target intake compared with 65% in the RC group (P <0.01). There were no differences in birth weight, rate of large-for-gestational-age infants, percent fat mass, or fat-free mass between groups. CONCLUSIONS An intervention to reduce carbohydrate intake in GDM did not raise ketones to clinical significance, possibly because the target of 135 g/d was difficult to achieve in pregnancy. Feeding studies with food provision may be needed to assess the benefits and risks of low-carbohydrate diets. This trial was registered at www.anzctr.org.au as ACTRN12616000018415.

OBJECTIVE Maternal satisfaction and comfort may in part depend on fasting instruction given during labor. This study aimed to assess the satisfaction and the wishes of parturients with regards to fasting during labor. STUDY DESIGN This prospective cohort study was conducted among parturients assessing the fasting instructions they were given. We assessed whether women did have any oral intake during labor and focused on women's view of fasting during labor. Maternal discomfort related to thirst and hunger was assessed using 0-10 scales. RESULTS A total of 193 women were included, among whom 71 (37 %) received spontaneously given instructions and 60 (31 %) received instruction upon request. One hundred sixteen (60 %) women were allowed to drink clear fluids, in a limited way for 106 women (91 % of those concerned); 119 women did drink clear fluids during labor. One hundred thirty-two (68 %) women had a thirst-related discomfort score ≥ 4 without any statistical difference whether they had or had not drunk clear fluids. Colder water, unrestricted volume of water and sweet drink were desired by 74 (64 %), 38 (33 %) and 28 (24 %) women who had been allowed to drink, respectively. CONCLUSION These results emphasize that thirst contributes to maternal discomfort during labor. Permitting limited intake of water does not ensure high maternal satisfaction. Fresh clear fluids, unrestricted amounts of fluids and sweet fluids could contribute to improve maternal comfort.

Abstract
Fasting the Holy month of Ramadan constitutes one of the five pillars of the Muslim faith. Although there is some evidence that intermittent fasting during Ramadan may be of benefit in losing weight and cardiometabolic risk factors, there is no strong evidence these benefits apply to people with diabetes. The American Diabetes Association/European Association for the Study of Diabetes consensus recommendations emphasize the importance of patient factors and comorbidities when choosing diabetes medications including the presence of comorbidities, atherosclerotic cardiovascular disease, heart failure, chronic kidney disease, hypoglycemia risk, weight issues and costs. Structured education and pre-Ramadan counseing are key components to successful management of patients with diabetes. These should cover important aspects like glycemic targets, self-monitoring of blood glucose, diet, physical activity including Taraweeh prayers, medication and dose adjustment, side effects and when to break the fast. The decision cycle adapted for the specific situation of Ramadan provides an aid for such an assessment. Children with type 1 diabetes should strongly be advised not to fast due to the high risk of acute complications such as hypoglycemia and probably diabetic ketoacidosis (DKA), although there is very little evidence that DKA is increased in Ramadan. Pregnant women with diabetes or gestational diabetes should be advised to avoid fasting because of possible negative maternal and fetal outcomes. Hypoglycemia is a common concern during Ramadan fasting. To prevent hypoglycemic and hyperglycemic events, we recommend the adoption of diabetes self-management education and support principles. The use of the emerging technology and continuous glucose monitoring during Ramadan could help to recognize hypoglycemic and hyperglycemic complications related to omission and/or medication adjustment during fasting; however, the cost represents a significant barrier.

Abstract
Diabetic ketoacidosis, a life-threatening complication of type 1 diabetes mellitus, is a common cause of presentation to EDs. Two new drug classes have been found to cause ketoacidosis with distinctive presentations. The sodium-glucose transport protein 2 inhibitors used in the management of type 2 diabetes mellitus may present with ketoacidosis with normal glucose levels. Ketoacidosis with these medications may be prolonged and recur after initial resolution. Checkpoint inhibitors may present with fulminant diabetic ketoacidosis in individuals with previously normal glucose tolerance. Ketoacidosis may also occur as a result of starvation and alcohol excess, as well as a number of rare causes. Other causes of metabolic acidosis with both high and normal anion gap need to be considered in the differential diagnosis of ketoacidosis. Diabetic ketoacidosis may also present with biochemical changes suggestive of myocardial ischaemia and pancreatitis in the absence of these pathologies. The present paper reviews ketone body metabolism, ketone testing and the causes and differential diagnosis of ketoacidosis with particular relevance to emergency medicine.

Abstract
AIMS To examine the relative association between fasting plasma glucose vs post-load (1-h and 2-h) glucose levels based on the oral glucose tolerance test in pregnancy and large-for-gestational-age and hypertensive disorders of pregnancy outcomes. METHODS All live singleton births between October 2008 and December 2014 in Alberta, Canada were included. Gestational diabetes mellitus was diagnosed using Diabetes Canada criteria. Logistic regression models were used to examine the association between fasting plasma glucose vs post-load values and large-for-gestational-age infants and hypertensive disorders of pregnancy after adjusting for maternal characteristics and pharmaceutical intervention in gestational diabetes pregnancies. RESULTS Among 257 547 pregnancies, 208 344 (80.9%) had negative 50-g glucose challenge tests, 36 261 (14.1%) had negative 75-g oral glucose tolerance tests, and 12 942 (5.0%) had gestational diabetes based on either elevated fasting plasma glucose (n=4130, 1.6%) or elevated 1-h and/or 2-h oral glucose tolerance test values (n=8812, 3.4%). Large-for-gestational-age and hypertensive disorders of pregnancy rates were 8.1% and 5.1% in negative glucose challenge test pregnancies, 11.0% and 7.0% in negative oral glucose tolerance test pregnancies, 22.4% and 11.9% in gestational diabetes pregnancies with elevated fasting plasma glucose, and 9.1% and 8% in gestational diabetes pregnancies with elevated post-load levels, respectively. Among gestational diabetes pregnancies, those with elevated fasting plasma glucose were at higher risk of large-for-gestational age (adjusted odds ratio 2.66, 95% CI 2.39-2.96) and hypertensive disorders of pregnancy (adjusted odds ratio 1.51, 95% CI 1.33-1.72) outcomes relative to pregnancies with post-load glucose elevations only. Fasting plasma glucose remained significantly associated with adverse outcomes in gestational diabetes pregnancies with and without pharmacological intervention. CONCLUSIONS Elevated fasting plasma glucose in women with gestational diabetes is a stronger predictor of large-for-gestational-age and hypertensive disorders of pregnancy outcomes than elevated post-load glucose.

Abstract
Pregnancy is associated with physiological adaptions that affect every organ system. Changes in liver function in pregnancy have important effects on nutrient metabolism, protein synthesis, and the biotransformation of substances in preparation for excretion. A clear understanding of the anatomic and functional changes of the hepatobiliary system is necessary for the diagnosis and evaluation of disease, as well as understanding how these changes predispose women to pregnancy-specific hepatic conditions. In this review, the effect of gestational changes in hepatobiliary function on laboratory tests and the role of diagnostic imaging of the liver and gallbladder in pregnancy will be discussed.

Abstract
The extreme metabolic demands of pregnancy require coordinated metabolic adaptations between mother and fetus to balance fetal growth and maternal health with nutrient availability. To determine maternal and fetal contributions to metabolic flexibility during gestation, pregnant mice with genetic impairments in mitochondrial carbohydrate and/or lipid metabolism were subjected to nutrient deprivation. The maternal fasting response initiates a fetal liver transcriptional program marked by upregulation of lipid- and peroxisome proliferator-activated receptor alpha (Pparα)-regulated genes. Impaired maternal lipid metabolism alters circulating lipid metabolite concentrations and enhances the fetal response to fasting, which is largely dependent on fetal Pparα. Maternal fasting also improves metabolic deficits in fetal carbohydrate metabolism by increasing the availability of alternative substrates. Impairment of both carbohydrate and lipid metabolism in pregnant dams further exacerbates the fetal liver transcriptional response to nutrient deprivation. Together, these data demonstrate a regulatory role for mitochondrial macronutrient metabolism in mediating maternal-fetal metabolic communication, particularly when nutrients are limited.

Abstract
Diabetic ketoacidosis (DKA) in pregnancy is associated with high fetal mortality rates. A small percentage of DKA occurs in the absence of high glucose levels seen in traditional DKA. Prompt recognition and management is crucial. We report a case of a 30-year-old pregnant woman with type 1 diabetes mellitus admitted with euglycemic DKA (blood glucose <200 mg/dL). Initial laboratory testing revealed a severe anion gap acidosis with pH 7.11, anion gap 23, elevated β-hydroxybutyric acid of 9.60 mmol/L, and a blood glucose of 183 mg/dL—surprisingly low given her severe acidosis. The ketoacidosis persisted despite high doses of glucose and insulin infusions. Due to nonresolving acidosis, her hospital course was complicated by spontaneous intrauterine fetal demise. Euglycemia and severe acidosis continued to persist until delivery of fetus and placenta occurred. It was observed that the insulin sensitivity dramatically increased after delivery of fetus and placenta leading to rapid correction of ketoacidosis. This case highlights that severe ketonemia can occur despite the absence of severely elevated glucose levels. We discuss the mechanism that leads to this pathophysiologic state and summarize previously published case reports about euglycemic DKA in pregnancy.

Ketonuria Is Associated with Changes to the Abundance of Roseburia in the Gut Microbiota of Overweight and Obese Women at 16 Weeks Gestation: A Cross-Sectional Observational Study. Nutrients 2019; 11:nu11081836.

Abstract
The gut microbiome in pregnancy has been associated with various maternal metabolic and hormonal markers involved in glucose metabolism. Maternal ketones are of particular interest due to the rise in popularity of low-carbohydrate diets. We assessed for differences in the composition of the gut microbiota in pregnant women with and without ketonuria at 16 weeks gestation. Fecal samples were obtained from 11 women with fasting ketonuria and 11 matched controls. The samples were analyzed to assess for differences in gut microbiota composition by 16S rRNA sequencing. Supervised hierarchical clustering analysis showed significantly different beta-diversity between women with and without ketonuria, but no difference in the alpha-diversity. Group comparisons and network analysis showed that ketonuria was associated with an increased abundance of the butyrate-producing genus Roseburia. The bacteria that contributed the most to the differences in the composition of the gut microbiota included Roseburia, Methanobrevibacter, Uncl. RF39, and Dialister in women with ketonuria and Eggerthella, Phascolarctobacterium, Butyricimonas, and Uncl. Coriobacteriaceae in women without ketonuria. This study found that the genus Roseburia is more abundant in the gut microbiota of pregnant women with ketonuria. Roseburia is a butyrate producing bacterium and may increase serum ketone levels.

Abstract
Many pregnant Muslim women fast during the Muslim holy month of Ramadan. A number of studies have reported negative life outcomes in adulthood for children who were prenatally exposed to Ramadan. However, other studies document minimal to no impact on neonatal indicators. Using data from the Indonesian Family Life Survey consisting of 45,246 observations of 21,723 children born to 9771 mothers, we contribute to the current discussion on prenatal exposure to Ramadan by examining the effects on stature (height-for-age Z-scores, weight-for-age Z-scores, and body-mass-index-for-age Z-scores: HAZ, WAZ, and BAZ, respectively) from early childhood to late adolescence (0-19 years of age). We introduce an objective mother's religiosity indicator to improve the intention-to-treat estimations. Children were classified into three groups based on their mother's religion-religiosity: religious Muslims, less-religious Muslims, and non-Muslims. Using cluster-robust mother fixed-effects, we found negative effects on stature for children born to religious Muslim mothers. The effects were age-dependent and timing-sensitive. For example, children born to religious Muslim mothers were shorter in late adolescence (15-19 years of age) compared to their unexposed siblings if they were prenatally exposed in the first trimester of pregnancy (HAZ difference = -0.105 SD; p-val. <0.05). Interestingly, we found positive effects on stature for exposed less-religious Muslim children that peak in early adolescence (10-14 years of age) and negative effects on stature for exposed non-Muslim children that occur only in early childhood (0-4 years of age). We nuance our discussion of health and socioeconomic factors to explain these surprising results.

Abstract
Background There are controversies over the effects of Ramadan fasting on pregnancy outcomes, and women’s perspectives of fasting are diverse. This study aimed to assess the perspectives and pregnancy outcomes of maternal Ramadan fasting in the second trimester of pregnancy. Methods A case-control study was conducted at Hawler Maternity Teaching Hospital of Erbil, Iraq from October 2017 to January 2018. Out of 301 participating women, 155 fasted during the second trimester of their current pregnancy, while the remaining 146 did not. Mothers were asked concerning their fasting behaviors and perception of fasting during pregnancy. The main outcomes of this study were gestational diabetes, preterm labour, preeclampsia, low birth weight, Apgar score, height, weight, and head circumference of the newborn. Results About 80% of the women in the fasting group fasted for 21–29 days during Ramadan, out of whom 38.7% completed fasting for the entire Ramadan period. The results revealed that the decision to fast during pregnancy was negatively associated with the mother’s educational level and occupation. Weight gain during pregnancy in the fasting women was approximately 0.4 kg less than those who did not fast. The incidence of gestational diabetes was 2.6% in the fasting women, while it was 8.3% in the non-fasting mothers (P = 0.02). Regression analysis showed that women who did not fast during the second trimester of pregnancy were 1.51 times more likely to develop gestational diabetes [odd ratio (OR) 1.51; 95% confidence intervals (CI) 0.06, 0.74, P = 0.01]. It was also found that among the women in the fasting categories, those who fasted for 21–29 days during pregnancy had a lower risk of gestational diabetes compared to the other groups. More than half of the mothers in the fasting group (60%) perceived that fasting during pregnancy was compulsory for healthy and non-healthy women, comparing with those who did not fast. Conclusion It was found that fasting during the second trimester of the pregnancy decreased the risk of gestational diabetes and excessive weight gain during pregnancy. Most of Iraqi women did not fully recognize their right to be exempted from fasting during pregnancy by the Islamic law.

Abstract
In this study, we estimate the long-run effects of early-life exposure to weather shocks on the height of primary school children. To estimate the global impacts on almost the entire child population in an industrializing country, we utilize both a unique nationwide multi-dimensional longitudinal dataset of Japanese children aged 6-11 and official monthly statistics on meteorological conditions in the 1920s. We observe that the exposure to cold waves in early-life exerted stunting effects on both the boys and girls. In the coldest regions in the northeastern area of Japan, the stunting effects of cold weather shocks on the boys and girls are estimated to be approximately 0.8 and 0.6 cm, respectively. Our observation indicates that prenatal (postnatal) exposure is important for the boys (girls). Our results suggest that the marginal effects of cold waves are stronger in the warmer regions than in the colder regions.

Abstract
Acute ketosis is an important physiological mechanism to prevent irreversible neurological damage from hypoglycaemia during starvation, and represents a significant metabolic stress. A cohort of children adapt to relatively short periods of reduced caloric intake by generating large quantities of ketone bodies. When excessive, the gastrointestinal symptoms of starvation ketosis such as nausea and pain may create a vicious cycle that delays spontaneous resolution. The presence of ketones can be dismissed as a normal feature of childhood metabolism, sometimes even when extreme. A broader understanding of this process under the banner of 'accelerated starvation of childhood' is helpful for clinicians managing acute illness in children. We advocate that children less than 7 years of age with a history suggestive of accelerated starvation of childhood should be screened by emergency clinicians for ketosis using a simple and cheap bedside capillary test, even if glucose levels are greater than 2.6 mmol/L. Identification and appropriate management of ketosis may alleviate the distressing gastrointestinal symptoms associated with many minor illnesses, and potentially prevent hypoglycaemia in some children. Appropriate advice to carers may be helpful to prevent further episodes. Illustrative case examples from our own practice are provided.

Abstract
Anion gap metabolic acidosis (AGMA) occurs when an anion gap exists along with metabolic acidosis, most commonly due to diabetic ketoacidosis (DKA) and lactic acidosis (LA). Isolated starvation ketoacidosis (ISK) is one of the rare causes of AGMA; however, it usually presents with a mild disturbance in pH. We report a rare case of a 45-year-old female with previously diagnosed squamous cell cancer (SCC) of the larynx. She presented to the emergency department complaining of difficulty in breathing following laryngectomy and tracheostomy for SCC. Her laboratory results on admission were consistent for isolated starvation ketoacidosis and the patient responded quickly to the appropriate treatment.

Abstract
Obstetric anesthesia has evolved over the course of its history to encompass comprehensive aspects of maternal care, ranging from cesarean delivery anesthesia and labor analgesia to maternal resuscitation and patient safety. Anesthesiologists are concerned with maternal and neonatal outcomes, and with preventing and managing complications that may present during childbirth. The current review will focus on recent advances in obstetric anesthesia, including labor anesthesia and analgesia, cesarean delivery anesthesia and analgesia, the effects of maternal anesthesia on breastfeeding and fever, and maternal safety. The impact of these advances on maternal and neonatal outcomes is discussed. Past and future progress in this field will continue to have significant implications on the health of women and children.

Abstract
Life-history theory predicts that access to limited resources leads to trade-offs between competing body functions. Women, who face higher costs of reproduction when compared to men, should be especially vulnerable to these trade-offs. We propose the 'cognitive costs of reproduction hypothesis', which states that energy trade-offs imposed by reproduction may lead to a decline in maternal cognitive function during gestation. In particular, we hypothesize that the decline in cognitive function frequently observed during pregnancy is associated with the allocation of resources between the competing energetic requirements of the mother's brain and the developing foetus. Several distinctive anatomical and physiological features including a high metabolic rate of the brain, large infant size, specific anatomical features of the placenta and trophoblast, and the lack of maternal control over glucose flow through the placenta make the occurrence of these trade-offs likely. Herein, we review several lines of evidence for trade-offs between gestation and cognition that are related to: (i) energy metabolism during reproduction; (ii) energy metabolism of the human brain; (iii) links between energy metabolism and cognitive function; and (iv) links between gestation and cognitive function. We also review evidence for the important roles of cortisol, corticotropin-releasing hormone and sex hormones in mediating the effects of gestation on cognition, and we discuss possible neurophysiological mechanisms underlying the observed effects. The evidence supports the view that energy trade-offs between foetal growth and maternal endocrine and brain function lead to changes in maternal cognition, and that this phenomenon is mediated by neuroendocrine mechanisms involving the hypothalamic-pituitary-adrenal axis, brainstem nucleus locus coeruleus and hippocampus.

Abstract
Many patients worldwide seek medical advice regarding safety of fasting during pregnancy. This issue lacks high quality evidence, which makes giving medical advice challenging. To aid decision making on this subject we performed an internet mediated survey to determine the expert opinion on this issue. The survey was answered by one hundred and eight obstetricians and gynecologists (OB/GYN). The questions were aimed at the content of the medical advice given to pregnant patients on Ramadan (for Muslim patients) and Yom Kippur (for Jewish patients) fasts. For both fasts, most physicians recommended against fasting on the second or third trimester, while fasting on the first trimester was controversial. Differences were found between medical advices provided by physicians according to their demographical characteristics. Regarding Ramadan fast, senior specialists were more lenient about fasting than younger specialists (62% and 35%, respectively, p = 0.01). As to Yom Kippur fast, religious and traditional physicians were more likely to permit fasting compared to their secular colleagues (53% and 25%, respectively, p = 0.01). Additionally, a comprehensive literature review was conducted revealing possible adverse maternal and fetal outcomes of fasting; however the risk for long term clinical complications is yet to be defined.

Abstract
Ramadan exposure in utero can be regarded as a natural experiment with which to study how nutritional conditions in utero influence susceptibility to disease later in life. We analyzed data from rural Burkina Faso on 41,025 children born between 1993 and 2012, of whom 25,093 were born to Muslim mothers. Ramadan exposure was assigned on the basis of overlap between Ramadan dates and gestation, creating 7 exclusive categories. We used proportional hazards regression with difference-in-differences analysis to estimate the association between Ramadan exposure at different gestational ages and mortality among children under 5 years of age. Under-5 mortality was 32 deaths per 1,000 child-years. Under-5 mortality among Muslims was 15% higher than that among non-Muslims (P < 0.001). In the difference-in-differences analysis, the occurrence of Ramadan during conception or the first or second trimester was associated with higher under-5 mortality rates among Muslims only. The mortality rates of children born to Muslim mothers were 33%, 29%, and 22% higher when Ramadan occurred during conception, the first trimester, and the second trimester, respectively, compared with children of non-Muslim mothers born at the same time (P = 0.01, P < 0.001, and P = 0.007). Having a Muslim mother was not associated with mortality when the child was not exposed to Ramadan, born during Ramadan, or exposed during the third trimester. Observance of Ramadan during early pregnancy can have detrimental consequences for the future health of the unborn child.

Abstract
While prenatal exposure to Ramadan has been shown to be negatively associated with general physical and mental health, studies on specific organs remain scarce. In this study, we explored whether Ramadan exposure during pregnancy affects the occurrence of wheezing, a main symptom of obstructive airway disease. Using data from the Indonesian Family Life Survey collected between 1997 and 2008 (waves 2-4), we compared wheezing occurrence among adult Muslims who had been in utero during Ramadan with that in adult Muslims who had not been in utero during Ramadan. Wheezing prevalence was higher among adult Muslims who had been in utero during Ramadan, independent of the pregnancy phase in which the exposure to Ramadan occurred. Moreover, this association tended to increase with age, being strongest among those aged about 45 years or older. This is in line with fetal programming theory, suggesting that impacts of in utero exposures often manifest only after reproductive age. Particularly strong associations were detected for smokers. The respiratory system of prenatally exposed Muslims thus seems to perform worse in mitigating later ex utero harmful influences such as smoking. This study suggests that exposure to Ramadan during pregnancy may have lasting consequences for adult lung functionality.

Abstract
INTRODUCTION Fasting during Ramadan while pregnant has been shown to have long-term negative effects on the offspring's physical and cognitive health. Even though most Muslims do not believe pregnant women are obligated to fast during Ramadan, fasting rates of up to 87% have been reported for pregnant women. No data exists to date about Ramadan adherence and behavior in Germany. METHODS The Mainz Study of Ramadan and Pregnancy surveyed pregnant Muslims and new Muslim mothers in Mainz between October 2016 and January 2017 and collected information on Ramadan adherence and behavior. We also collected data on personal characteristics and opinions, to identify determinants of fasting using statistical analysis. RESULTS We found that 43% of pregnant Muslim women fasted at least one day during Ramadan 2016. Women who fasted were significantly younger and less educated. There was no significant difference in terms of country of origin between those women who fasted and those who did not. Only 49% of women who fasted and 38% of women who did not fast discussed their Ramadan behavior with their doctor. Less than 2% of women reported being proactively approached by their doctor. CONCLUSION To ensure that pregnant Muslim women living in Germany can make their fasting decision based on objective information, it is necessary to raise awareness about Ramadan fasting during pregnancy among medical professionals in Germany.

Abstract
RATIONALE Pregnant women are more prone to ketosis due to the relative insulin resistance, accelerated lipolysis and increased free fatty acids. PATIENT CONCERNS We report a pregnant woman with hyperlipidemia, who experienced severe metabolic acidosis after a short period of starvation. DIAGNOSES Based on her clinical symptoms, exclusion diagnosis and therapeutic diagnosis, her condition was diagnosed as starvation ketoacidosis. INTERVENTIONS An emergency caesarean section under general anesthesia was implemented 2 hours after her admission. The metabolic acidosis was treated with fluid resuscitation using compound sodium lactate, bicarbonate, and 5% dextrose together with insulin 6U. OUTCOMES Both mother and baby were discharged clinically well. LESSONS Starvation ketoacidosis may happen in special patient who was in pregnancy and with severe hypertriglyceridemia, after just one day fasting and vomiting.

Abstract
Threatening refractory metabolic acidosis due to short-term starvation nondiabetic ketoacidosis is rarely reported. Severe ketoacidosis due to starvation itself is a rare occurrence, and more so in pregnancy with a concomitant stressful clinical situation. This case report presents a nondiabetic woman admitted in intensive care for respiratory failure type 1 during the third trimester of pregnancy with a severe metabolic acidosis refractory to medical treatment. We diagnosed the patient with acute starvation ketoacidosis based on her history and the absence of other causes of high anion gap metabolic acidosis after doing a rigorous analysis of her acid-base disorder.

Abstract
Background Ketonuria may be associated with adverse fetal outcomes. This study aimed to determine the prevalence of ketonuria at three time points in pregnancy and to assess whether ketonuria correlates with a clinical indication for performing a urine test. Methods Women had fasting urinary ketone levels measured at 16 and 28 weeks gestation and random ketone levels measured close to 36 weeks gestation. All ketone levels in the third trimester were recorded along with the clinical indication for the test. Results One hundred and eighty-seven women were included in the study. Twenty-two per cent of women had ketonuria at either 16 or 28 weeks gestation and 8% at 36 weeks gestation. Ketonuria was significantly more likely if a test was performed for a clinical indication (p = 0.0002). Conclusion Ketonuria in pregnancy is common affecting at least one in five women. Ketonuria is more common in women who have a clinical indication for performing a urine test.

Abstract
Fasting plasma glucose (FPG) is nowadays routinely measured during early pregnancy to detect preexisting diabetes (FPG ≥ 7 mmol/L). This screening has concomitantly led to identify early intermediate hyperglycemia, defined as FPG in the 5.1 to 6.9 mmol/L range, also early gestational diabetes mellitus (eGDM). Early FPG has been associated with poor pregnancy outcomes, but the recommendation by the IADPSG to refer women with eGDM for immediate management is more pragmatic than evidence based. Although eGDM is characterized by insulin resistance and associated with classical risk factors for type 2 diabetes and incident diabetes after delivery, it is not necessarily associated with preexisting prediabetes. FPG ≥ 5.1 mmol/L in early pregnancy is actually poorly predictive of gestational diabetes mellitus diagnosed after 24 weeks of gestation. An alternative threshold should be determined but may vary according to ethnicity, gestational age, and body mass index. Finally, observational data suggest that early management of intermediate hyperglycemia may improve prognosis, through reduced gestational weight gain and potential early introduction of hypoglycemic agents. Considering all these issues, we suggest an algorithm for the management of eGDM based on early FPG levels that would be measured in case of risk factors. Nevertheless, interventional randomized trials are still missing.

Abstract
Patients with succinyl-CoA:3-oxoacid CoA transferase (SCOT) deficiency and 3-hydroxy-3-methylglutaryl (HMG)-CoA lyase deficiency are at increased risk of developing metabolic acidosis and hypoglycemia during pregnancy, delivery, and postpartum period. This can be fatal if not treated appropriately. Pregnancy in such patients should be managed in a specialist center by a multidisciplinary team including metabolic physician, high-risk obstetrician, and metabolic dietician. We report two pregnancies in women with SCOT deficiency and HMG-CoA lyase deficiency, which were successfully managed at this tertiary care center. The patient with SCOT deficiency had recurrent ketoacidosis due to severe nausea and vomiting requiring several hospital admissions during pregnancy, while the patient with HMG-CoA lyase deficiency remained metabolically stable. Both patients, nevertheless, had normal delivery of live-born infants and had uneventful postpartum period.
