Effects of three different stimulations (acupuncture, moxibustion, acupuncture plus moxibustion) of BL.67 acupoint at small toe on fetal behavior of breech presentation
The aim of the study was to evaluate cardiovascular effects and fetal behavior during moxibustion, acupuncture or acupuncture plus moxibustion applied on the BL.67 acupoint of women (beside the outer corner of the 5th toenail) in fetal breech presentation. During the acupoint stimulation (20 min, two times a week), the women were submitted to computerized non-stress test. Fourteen cases were treated by both acupuncture and moxibustion, 15 cases by moxibustion and 10 cases by acupuncture. In 56% of cases, fetal position was converted from breech position to cephalic one; the success share was 80% for moxibustion, 28% for acupuncture, 57% for acupuncture plus moxibustion; the conversion, on average, was achieved after 3 sessions. Statistical analysis indicated that acupuncture plus moxibustion was able to reduce fetal heart rate during the application of stimuli while acupuncture and moxibustion separately did not affect such parameter. Moreover, moxibustion and acupuncture with moxibustion reduced fetal movements while acupuncture only appears ineffective. The present study suggests that fetal movements were reduced by both acupuncture plus moxibustion and moxibustion and that fetal heart rate was reduced just by acupuncture plus moxibustion. The mechanisms leading the effect on fetal heart rate and fetal movements remain to be clarified. Even though further studies are needed, such preliminar report mainly investigated the impact of different stimula on the BL.67 acupoint. Unfortunately these small series of data do not allow us to draw any conclusion about the effectiveness of the different treatments
Stillbirth occurrence during COVID-19 pandemic: A population-based prospective study
Objectives: Data collected worldwide on stillbirth (SB) rates during the Covid-19 pandemic are contradictory. Variations may be due to methodological differences or population characteristics. The aim of the study is to assess the changes in SB rate, risk factors, causes of death and quality of antenatal care during the pandemic compared to the control periods. Methods: This prospective study is based on the information collected by the Emilia-Romagna Surveillance system database. We conducted a descriptive analysis of SB rate, risk factors, causes of death and quality of cares, comparing data of the pandemic (March 2020-June 2021) with the 16 months before. Results: During the pandemic, the SB rate was 3.45/1,000 births, a value in line with the rates of previous control periods. Neonatal weight >90th centile was the only risk factor for SB that significantly changed during the pandemic (2.2% vs. 8.0%; p-value: 0.024). No significant differences were found in the distribution of the causes of death groups. Concerning quality of antenatal cares, cases evaluated with suboptimal care (5.2%) did not change significantly compared to the control period (12.0%), as well as the cases with less than recommended obstetric (12.6% vs. 14%) and ultrasound evaluations (0% vs. 2.7%). Conclusions: During the COVID-19 pandemic, no significant differences in SB rates were found in an area that maintained an adequate level of antenatal care. Thus, eventual associations between SB rate and the COVID-19 infection are explained by an indirect impact of the virus, rather than its direct effect
An update on the use of inositols in preventing gestational diabetes mellitus (GDM) and neural tube defects (NTDs)
INTRODUCTION: Obstetric history and maternal body composition and lifestyle may be associated with serious complications both for the mother, such as gestational diabetes mellitus (GDM), and for the fetus, including congenital malformations such as neural tube defects (NTDs). AREAS COVERED: In view of the recent knowledge, changes of nutritional and physical activity habits ameliorate glycemic control during pregnancy and in turn improve maternal and neonatal health outcomes. Recently, a series of small clinical and experimental studies indicated that supplementation with inositols, a family of insulin sensitizers, was associated with beneficial impact for both GDM and NTDs. EXPERT OPINION: Herein, we discuss the most significant scientific evidence supporting myo-inositol administration as a prophylaxis for the above-mentioned conditions
Mode of Delivery in Women with Stillbirth: Results of an Area-Based Italian Prospective Cohort Study
Introduction: The choice of the mode of delivery, in case of stillbirth (SB) (fetus non-viable >22 weeks' gestation), should consider maternal preference, gestational age, bishop score, the clinical condition of the woman, and her previous obstetric history. However, despite these clear indications, data on the effective implementation of the latter are lacking. The aim of our study is to evaluate the different modes of delivery in an Italian population of SBs, according to gestational age, parity, causes of death, obstetric history, and maternal characteristics. Material and Methods: This is an area-based, prospective cohort study conducted in Emilia Romagna, Italy between January 2014 to December 2020. Data included all cases of SB (>22 weeks). Results: From 2014 to 2020, 783 SB occurred out of a total of 232.506 births, with a SB rate of 3.3 per 1000. Labor was spontaneous in 85 (11%). Of remnant, 567 (73.6%) were induced and 118 (15.3%) had no labor. The mode of delivery was vaginal in most of the cases (649/770, 84.3%) and by cesarean section in 121/770 (15.7%) of cases. Emergency CS was most frequent and performed in 89/121 (73.5%) of total CS, representing 11.5% of SB deliveries. Mode of induction did not differ in relation to gestational age at stillbirth, while vaginal delivery was significantly higher in women induced with prostaglandins (p = 0.000) respect to other methods. Nulliparous women had a significantly higher need for multiple methods of induction (p = 0.000) respect multiparous and obese women used more frequently prostaglandins (p = 0.03) than other methods. Women with a history of previous CS presented a significantly higher rate of repeated elective CS (p = 0.000). Moreover, emergency CS was performed more frequent in obese (p = 0.02), diabetic (p = 0.04) and hypertensive (p = 0.04) women and in SB caused by placenta disorders, namely in abruptio placentae (p = 0.000). In the case of chorioamnionitis and funisitis women significantly were induced with prostaglandin (p = 0.000) and delivered vaginally (p = 0.000). Conclusions: The method of induction of labor and the mode of delivery in case of SB did not depend on gestational age at the diagnosis of death, while they are related to placenta disorders representing a relevant condition leading to emergency CS also after diagnosis of fetal death. These data could help obstetric providers in managing the deliveries of stillborn infants
Gestational weight gain in overweight and obese women enrolled in a healthy lifestyle and eating habits program
OBJECTIVES:
To determine whether changes in lifestyle in women with BMI > 25 could decrease gestational weight gain and unfavorable pregnancy outcomes.
METHODS:
Women with BMI > 25 were randomized at 1st trimester to no intervention or a Therapeutic Lifestyle Changes (TLC) Program including diet (overweight: 1700 kcal/day, obese: 1800 kcal/day) and mild physical activity (30 min/day, 3 times/week). At baseline and at the 36th week women filled-in a Food Frequency Questionnaire.
OUTCOMES:
gestational weight gain, gestational diabetes mellitus, gestational hypertension, preterm delivery. Data stratified by BMI categories.
RESULTS:
Socio-demographic features were similar between groups (TLC: 33 cases,
CONTROLS:
28 cases). At term, gestational weight gain in obese women randomized to TLC group was lower (6.7 ± 4.3 kg) versus controls (10.1 ± 5.6 kg, p = 0.047). Gestational diabetes mellitus, gestational hypertension and preterm delivery were also significantly lower. TLC was an independent factor in preventing gestational weight gain, gestational diabetes mellitus, gestational hypertension. Significant changes in eating habits occurred in the TLC group, which increased the number of snacks, the intake of fruits-vegetables and decreased the consumption of sugar.
CONCLUSIONS:
A caloric restriction associated to changes in eating behavior and constant physical activity, is able to reduce gestational weight gain and related pregnancy complications in obese women.Objectives: To determine whether changes in lifestyle in women with BMI > 25 could decrease gestational weight gain and unfavorable pregnancy outcomes.

From the zero-field metal-insulator transition in two dimensions to the quantum Hall transition: a percolation-effective-medium theory
Effective-medium theory is applied to the percolation description of the
metal-insulator transition in two dimensions with emphasis on the continuous
connection between the zero-magnetic-field transition and the quantum Hall
transition. In this model the system consists of puddles connected via saddle
points, and there is loss of quantum coherence inside the puddles. The
effective conductance of the network is calculated using appropriate
integration over the distribution of conductances, leading to a determination
of the magnetic field dependence of the critical density. Excellent
quantitative agreement is obtained with the experimental data, which allows an
estimate of the puddle physical parameters
Exposure to active and passive smoking during pregnancy and severe small for gestational age at term
Objective. The objective of this study was to assess the relationship between active smoking as well as environmental tobacco smoke (ETS) exposure and severe small for gestational age (SGA) at term in a sample of pregnant Italian women. Methods. A case-control study was conducted in nine cities in Italy between October 1999 and September 2000. Cases of severe SGA were singleton, live born, at term children with a birth weight5th percentile for gestational age. Controls (10:1 to cases) were enrolled from among singleton at term births that occurred in the same hospitals one or two days after delivery of the case, with a birth weight10th percentile for gestational age. A total of 84 cases of severe SGA and 858 controls were analyzed. A self-administered questionnaire was used to assess active smoking and ETS exposure, as well as potential confounders. Results. Multivariate logistic regression analysis showed a relationship between active smoking during pregnancy and severe SGA (adjusted odds ratio (OR) 2.10, 95% confidence interval (CI) 1.13-3.68). ETS exposure was associated with severe SGA (adjusted OR 2.51, 95% CI 1.59-3.95) with a dose-response relationship to the number of smokers in the home
Continuous glucose monitoring in very preterm infants: A randomized controlled trial
BACKGROUND AND OBJECTIVES:
Impaired glucose control in very preterm infants is associated with increased morbidity, mortality, and poor neurologic outcome. Strategies based on insulin titration have been unsuccessful in achieving euglycemia in absence of an increase in hypoglycemia and mortality. We sought to assess whether glucose administration guided by continuous glucose monitoring (CGM) is more effective than standard of care blood glucose monitoring in maintaining euglycemia in very preterm infants.
METHODS:
Fifty newborns ≤32 weeks’ gestation or with birth weight ≤1500 g were randomly assigned (1:1) within 48-hours from birth to receive computer-guided glucose infusion rate (GIR) with or without CGM. In the unblinded CGM group, the GIR adjustments were driven by CGM and rate of glucose change, whereas in the blinded CGM group the GIR was adjusted by using standard of care glucometer on the basis of blood glucose determinations. Primary outcome was percentage of time spent in euglycemic range (72–144 mg/dL). Secondary outcomes were percentage of time spent in mild (47–71 mg/dL) and severe (<47 mg/dL) hypoglycemia; percentage of time in mild (145–180 mg/dL) and severe (>180 mg/dL) hyperglycemia; and glucose variability.
RESULTS:
Neonates in the unblinded CGM group had a greater percentage of time spent in euglycemic range (median, 84% vs 68%, P < .001) and decreased time spent in mild (P = .04) and severe (P = .007) hypoglycemia and in severe hyperglycemia (P = .04) compared with the blinded CGM group. Use of CGM also decreased glycemic variability (SD: 21.6 ± 5.4 mg/dL vs 27 ± 7.2 mg/dL, P = .01; coefficient of variation: 22.8% ± 4.2% vs 27.9% ± 5.0%; P < .001).
CONCLUSIONS:
CGM-guided glucose titration can successfully increase the time spent in euglycemic range, reduce hypoglycemia, and minimize glycemic variability in preterm infants during the first week of life.

Systemic thromboembolism from a misdiagnosed non-bacterial thrombotic endocarditis in a patient with lung cancer: A case report
Thromboembolic events are frequent in patients with cancer, commonly involving the venous and pulmonary circulation. The arterial system is rarely implicated in embolism and, when involved, a cardiogenic origin should always be excluded. In the present study, a case of a patient who developed multiple embolic events concomitantly with the diagnosis of locally-advanced non-small cell lung cancer with high expression levels of programmed death-ligand 1 (PD-L1) in >50% of tumor cells is reported. A cardiac defect interpreted as a patent foramen ovale required low molecular weight heparin administration. Despite the anti-coagulant therapy, before first-line anticancer treatment with pembrolizumab immunotherapy could be administered due to high PD-L1 expression levels, a new hospitalization was required due to the onset of novel ischemic manifestation. New transthoracic and transesophageal echocardiography revealed a previously misdiagnosed vegetation of the mitral valve that caused systemic embolization. The lack of any sign of infection led to the diagnosis of a non-bacterial thrombotic endocarditis (NBTE), whose embolic sprouting gave rise to the widespread ischemic events. No active anticancer treatment was feasible due to the rapid progression of the disease. NBTE can evolve quickly, eventually preventing any chance of treatment targeting the primary cause, which in the present study was lung cancer. If NBTE can be correctly diagnosed sooner then there may be the potential for anticancer therapy that does not worsen the hypercoagulability state, thus improving cancer-associated survival
