AbstractMaternal obesity/overweight during pregnancy has reached epidemic proportions and has been linked with adverse outcomes for the offspring, including cognitive impairment and increased risk for neuropsychiatric disorders. Prior neuroimaging investigations have reported widespread aberrant functional connectivity and white matter tract abnormalities in neonates born to obese mothers. Here we explored whether maternal pre-pregnancy adiposity is associated with alterations in local neuronal synchrony and distal connectivity in the neonate brain. 21 healthy mother-neonate dyads from uncomplicated pregnancies were included in this study (age at scanning 26.14 ± 6.28 days, 12 male). The neonates were scanned with a 6-min resting-state functional magnetic resonance imaging (rs-fMRI) during natural sleep. Regional homogeneity (ReHo) maps were computed from obtained rs-fMRI data. Multiple regression analysis was performed to assess the association of pre-pregnancy maternal body-mass-index (BMI) and ReHo. Seed-based connectivity analysis with multiple regression was subsequently performed with seed-ROI derived from ReHo analysis. Maternal adiposity measured by pre-pregnancy BMI was positively associated with neonate ReHo values within the left superior frontal gyrus (SFG) (FWE-corrected p < 0.005). Additionally, we found both positive and negative associations (p < 0.05, FWE-corrected) for maternal pre-pregnancy BMI and seed-based connectivity between left SFG and prefrontal, amygdalae, basal ganglia and insular regions. Our results imply that maternal pre-pregnancy BMI associates with local and distal functional connectivity within the neonate left superior frontal gyrus. These findings add to the evidence that increased maternal pre-pregnancy BMI has a programming influence on the developing neonate brain functional networks.

Abstract Introduction: Maternal obesity/overweight during pregnancy has reached epidemic proportions and has been linked with adverse outcomes for the offspring, including cognitive impairment and increased risk for neuropsychiatric disorders. Prior neuroimaging investigations have reported widespread aberrant functional connectivity and white matter tract abnormalities in neonates born to obese mothers. Here we explored whether maternal pre-pregnancy adiposity is associated with alterations in local neuronal synchrony in the neonate brain. Methods: 21 healthy mother-neonate dyads from uncomplicated pregnancies were included in this study (age at scanning 26.14 ± 6.28 days, 12 male). The neonates were scanned with a 6-minute resting-state functional magnetic resonance imaging (rs-fMRI) during natural sleep. Regional homogeneity (ReHo) maps were computed from obtained rs-fMRI data. Multiple regression analysis was performed to assess the association of pre-pregnancy maternal body-mass-index (BMI) and ReHo. Results: Maternal adiposity measured by pre-pregnancy BMI was positively associated with neonate ReHo values within the left superior frontal gyrus (FDR/FWE –corrected p < 0.005). Conclusions: Our results imply that maternal pre-pregnancy BMI associates with local functional synchrony within the neonate left superior frontal gyrus. In line with previous studies, our findings indicate that maternal pre-pregnancy BMI has a programming influence on the developing neonate brain functional networks.

Objective. Several studies have shown an increased risk for neural tube defects associated with prepregnancy maternal obesity. Because few recent studies have examined the relation between maternal prepregnancy obesity and overweight and other birth defects, we explored the relation for several birth defects and compared our findings with those of previous studies. Methods. We conducted a population-based case-control study of several selected major birth defects using data from the Atlanta Birth Defects Risk Factor Surveillance Study. Mothers who delivered an infant with and without selected birth defects in a 5-county metropolitan Atlanta area between January 1993 and August 1997 were interviewed. Maternal body mass index (BMI) was calculated from self-reported maternal prepregnancy weight and height. Women with known preexisting diabetes were excluded. The risks for obese women (BMI ≥30) and overweight women (BMI 25.0–29.9) were compared with those for average-weight women (BMI 18.5–24.9). Results. Obese women were more likely than average-weight women to have an infant with spina bifida (unadjusted odds ratio [OR]: 3.5; 95% confidence interval [CI]: 1.2–10.3), omphalocele (OR: 3.3; 95% CI: 1.0–10.3), heart defects (OR: 2.0; 95% CI: 1.2–3.4), and multiple anomalies (OR: 2.0; 95% CI: 1.0–3.8). Overweight women were more likely than average-weight women to have infants with heart defects (OR: 2.0; 95% CI: 1.2–3.1) and multiple anomalies (OR: 1.9; 95% CI: 1.1–3.4). Conclusions. Our study confirmed the previously established association between spina bifida and prepregnancy maternal obesity and found an association for omphalocele, heart defects, and multiple anomalies among infants of obese women. We also found an association between heart defects and multiple anomalies and being overweight before pregnancy. A higher risk for some birth defects is yet another adverse pregnancy outcome associated with maternal obesity. Obesity prevention efforts are needed to increase the number of women who are of healthy weight before pregnancy.

Abstract Objectives Maternal obesity during pregnancy is associated with adverse intrauterine events and fetal outcomes and may increase the risk of obesity and metabolic disease development in offspring. Higher parity, regardless of socioeconomic status, is associated with increased maternal body mass index (BMI). In this study, we examined the relationship between parity, maternal obesity, and fetal outcomes in a large sample of mother-neonate pairs from Lower Saxony, Germany. Methods This retrospective cohort study examined pseudonymized data of a non-selected singleton cohort from Lower Saxony’s statewide quality assurance initiative. 448,963 cases were included. Newborn outcomes were assessed in relation to maternal BMI and parity. Results Maternal obesity was associated with an increased risk of placental insufficiency, chorioamnionitis, and fetal distress while giving birth. This effect was present across all parity groups. Fetal presentation did not differ between BMI groups, except for the increased risk of high longitudinal position and shoulder dystocia in obese women. Maternal obesity was also associated with an increased risk of premature birth, low arterial cord blood pH and low 5-min APGAR scores. Conclusions Maternal obesity increases the risk of adverse neonatal outcomes. There is a positive correlation between parity and increased maternal BMI. Weight-dependent fetal risk factors increase with parity, while parity-dependent outcomes occur less frequently in multipara. Prevention and intervention programs for women planning to become pregnant can be promising measures to reduce pregnancy and birth complications.

Recent studies have shown that maternal obesity is associated with increased risk of wheezing in the offspring. We assessed whether impaired neonatal lung function could explain this association.We measured neonatal lung function in 2606 children of our prospective birth cohort. Information about daily symptoms of wheezing was obtained using questionnaires. Consultations and prescriptions for wheezing illnesses were derived from general practitioner patient files.Higher maternal body mass index (BMI) was associated with increased risk of wheezing in the first year of life and more consultations and prescriptions for wheezing illnesses until the age of 5 years. Lung function could partially explain the association with wheezing in the first year of life. Adding respiratory resistance to the model decreased the incidence rate ratio from 1.023 (95% CI 1.008–1.039) to 1.015 (95% CI 0.998–1.032). Anthropometrics of the 5-year-olds largely explained the association with consultations. Intermediates or confounders could not explain the association with prescriptions.There is an association between higher maternal BMI and increased risk of wheezing illnesses. In the first year of life, it is largely explained by an impaired lung function in early life, especially in children of nonatopic mothers. At the age of 5 years, infant lung function is of minor influence in this association.

Introduction: Maternal nutrition plays an important role in maternal and fetal outcomes. The lowmaternal BMI or Obesity are both associated with adverse outcomes. Objectives: To evaluate theimpact of the maternal body mass index on the pregnancy outcome and neonatal outcomes.Materials and Methods: This is a prospective cohort study in which a total of 200 patients meetingthe inclusion criteria were enrolled in the study after informed consent of which 100 patientsenrolled after 18 weeks of gestation had a low BMI and 100 patients with a higher BMI than normal.Results: Pregnant females having low BMI as baseline had more risk of IUGR, fetal distress and lowbirth weight in newborns while those having high maternal BMI had more incidence of PIH inmothers, oligohydramnios, increased birth weight, increased risk of LSCS and NICU admissions anddelayed maternal wound healing. Conclusion: The health of women, throughout their childbearingages, should be cared, to improve their obstetrical and perinatal outcomes. Also, the high-riskgroups should be managed properly.

Objective To estimate whether obese women have an increased risk of orofacial clefts in their offspring, compared with average-weight women. Design and Participants The study was based on information on maternal body mass index (BMI) collected in early pregnancy and on the existence of orofacial clefts in the offspring, ascertained from multiple sources. The study included 1686 women who had infants with an orofacial cleft and as controls all delivered women (n = 988,171) during the study period, 1992 through 2001. Infants with chromosome anomalies were excluded. The women were divided into underweight (BMI <19.8), average weight (reference group, BMI 19.8 to 26), overweight (BMI 26.1 to 29), and obese (BMI >29). Adjustments were made for year of birth, maternal age, parity, and maternal smoking. Results Obese (BMI >29) mothers had an overall increased risk for having an infant with orofacial clefts: odds ratio 1.30 (95% confidence interval 1.11 to 1.53). This increased risk was higher when the cleft was associated with other major malformations than when it was isolated. There was no statistically significant difference between the risk estimates for cleft lip and cleft palate. Conclusions In this large sample, a positive association appears between maternal obesity in early pregnancy and orofacial clefts in the offspring. The explanation for this association is not known, but a relationship with undetected type 2 diabetes is one possibility.

Abstract Background It is unclear whether sarcoidosis, a multisystem inflammatory disease, is associated with adverse pregnancy outcomes. We aimed to assess the risk of adverse maternal and infant outcomes in sarcoidosis pregnancies, focused on first births. Methods Using a population-based cohort study design and Swedish national registers (2002–2013), we identified 182 singleton first pregnancies in the Medical Birth Register with at least two maternal ICD-coded sarcoidosis visits prior to pregnancy in the National Patient Register. Modified Poisson regression models estimated relative risks (RR) of adverse outcomes in sarcoidosis pregnancies compared to the general population adjusted for maternal age at delivery, calendar year and educational level. Some models were additionally adjusted for maternal body mass index and smoking status. Results The prevalence of pre-existing diabetes and hypertension was higher in mothers with sarcoidosis than those without sarcoidosis. Mothers with sarcoidosis had an increased risk of preeclampsia/eclampsia (RR 1.6; 95%CI 1.0, 2.6) and cesarean delivery (RR 1.3; 95%CI 1.0, 1.6). There were < 5 stillbirths and cases of infection and no cases of placental abruption, venous thromboembolism, cardiac arrest or maternal death. Newborns of first-time mothers with sarcoidosis had a 70% increased risk of preterm birth (RR 1.7; 95%CI 1.1, 2.5). There was an increased risk of birth defects (RR 1.6; 95%CI 0.9, 2.8) the majority of which were non-cardiac. Conclusions Sarcoidosis is associated with increased risks for preeclampsia/eclampsia, cesarean delivery, preterm birth and some birth defects. Awareness of these conditions may prevent possible pregnancy complications in mothers with sarcoidosis and their newborns.

Background: Recent data advocate adoption of a more intensive treatment strategy for management of blood pressure (BP). </P><P> Objective: We investigated whether the overall effects of the Systolic Blood Pressure Intervention Trial (SPRINT) are applicable to cardiovascular disease (CVD) patients. </P><P> Methods: In a post hoc analysis we analyzed data from SPRINT that randomly assigned 9361 individuals to a systolic BP (SBP) target of <120 mmHg (intensive treatment) or <140 mmHg (standard treatment). 1562 patients had clinically evident CVD (age=70.3±9.3 years, 24% females) at study entry and were followed for 3.1 years. Further, we assessed the effect of low (<150 mmHg) baseline SBP on outcome. </P><P> Results: In CVD patients, there was no benefit from the intensive treatment regarding all endpoints, except for a marginally significant benefit on all-cause mortality (hazard ratio [HR]: 0.67; 95% confidence interval [CI], 0.45 to 1.00; p=0.0509). Further, while there was no increase in serious adverse events (SAE) in the intensive group, there was increased risk for study-related SAE, acute renal failure and electrolyte abnormalities. In patients with low baseline SBP there was a beneficial effect on allcause mortality (HR: 0.56; 95% CI: 0.33 to 0.96; p=0.033), but with greater stroke incidence (HR: 2.94; 95% CI: 1.04 to 8.29; p=0.042). </P><P> Conclusion: We confirm the beneficial effect of the intensive strategy in SPRINT study on all-cause mortality and the harmful effect on specific adverse outcomes in patients with CVD. However, in patients with low baseline SBP stroke may increase.

Treatment Of Diabetes

The cardiac effects of exogenously administered insulin for the treatment of diabetes (DM) have recently attracted much attention. In particular, it has been questioned whether insulin is the appropriate treatment for patients with type 2 diabetes mellitus and heart failure. While several old and some new studies suggested that insulin treatment has beneficial effects on the heart, recent observational studies indicate associations of insulin treatment with an increased risk of developing or worsening of pre-existing heart failure and higher mortality rates. However, there is actually little evidence that the associations of insulin administration with any adverse outcomes are causal. On the other hand, insulin clearly causes weight gain and may also cause serious episodes of hypoglycemia. Moreover, excess of insulin (hyperinsulinemia), as often seen with the use of injected insulin, seems to predispose to inflammation, hypertension, dyslipidemia, atherosclerosis, heart failure, and arrhythmias. Nevertheless, it should be stressed that most of the data concerning the effects of insulin on cardiac function derive from in vitro studies with isolated animal hearts. Therefore, the relevance of the findings of such studies for humans should be considered with caution. In the present review, we summarize the existing data about the potential positive and negative effects of insulin on the heart and attempt to answer the question whether any adverse effects of insulin or the consequences of hyperglycemia are more important and may provide a better explanation of the close association of DM with heart failure.

AbstractThe SARS-Cov-2 pandemic in 2020 has caused oncology teams around the world to adapt their practice in the aim of protecting patients. Early evidence from China indicated that patients with cancer, and particularly those who had recently received chemotherapy or surgery, were at increased risk of adverse outcomes following SARS-Cov-2 infection. Many registries of cancer patients infected with SARS-Cov-2 emerged during the first wave. We collate the evidence from these national and international studies and focus on the risk factors for patients with solid cancers and the contribution of systemic anti-cancer treatments (SACT—chemotherapy, immunotherapy, targeted and hormone therapy) to outcomes following SARS-Cov-2 infection. Patients with cancer infected with SARS-Cov-2 have a higher probability of death compared with patients without cancer. Common risk factors for mortality following COVID-19 include age, male sex, smoking history, number of comorbidities and poor performance status. Oncological features that may predict for worse outcomes include tumour stage, disease trajectory and lung cancer. Most studies did not identify an association between SACT and adverse outcomes. Recent data suggest that the timing of receipt of SACT may be associated with risk of mortality. Ongoing recruitment to these registries will enable us to provide evidence-based care.
