Endoscopic Placental Laser Coagulation in Monochorionic Diamniotic Twins with Type II Selective Fetal Growth Restriction.

OBJECTIVE: To determine predictors of survival in monochorionic diamniotic twins with selective fetal growth restriction type II (sFGR-II), with or without twin-to-twin transfusion syndrome (TTTS), treated by endoscopic placental laser coagulation. METHODS: Laser surgery was performed at 20 (15-27) weeks' gestation in 405 cases of sFGR-II with and 142 without coexisting TTTS. Multivariable logistic regression analysis was performed to determine significant predictors of survival to discharge from hospital. RESULTS: There was survival of the small twin in 216 (39.5%) and of the large twin in 379 (69.3%) cases. Significant predictors of survival of both the small and larger twin were ductus venosus Doppler findings in the small twin, gestational age at laser and cervical length, but not the presence of TTTS or Doppler findings in the large twin. CONCLUSIONS: In sFGR-II, survival after laser surgery is primarily dependent on the condition of the small twin.

Association of limited English proficiency with emergency department irregular departures and return visits: A cross-sectional cohort study in the Upper Midwest between January 2018 and December 2021.

OBJECTIVES: Patients with limited English proficiency (LEP) have been shown to experience disparities in emergency department (ED) care. The objectives of this study were to examine the associations between LEP and irregular ED departures and return ED visits. METHODS: We conducted a multicenter cross-sectional analysis of 18 EDs within an integrated health system in the upper Midwest from January 1, 2018, to December 31, 2021. ED visits of pediatric and adult patients who were discharged on the index visit were included for analysis. We analyzed the association of LEP with irregular departures, 72-h and 7-day return visits, and ED disposition at the time of that return visit. Multivariable model associations were calculated using generalized estimating equations and reported as odds ratios (OR) with 95% confidence intervals (CIs). RESULTS: A total of 745,464 total ED visits were analyzed, including 27,906 (3.7%) visits among patients with LEP. The most common preferred languages among patients with LEP were Spanish (12,759; 45.7%), Somali (4978; 17.8%), and Arabic (3185; 11.4%). After multivariable adjustment there were no differences in proportions of irregular departures (OR 1.09, 95% CI 0.99-1.21), 72-h returns (OR 0.99, 95% CI 0.92-1.06), or 7-day returns (OR 0.99, 95% CI 0.93-1.05) between patients with LEP or English proficiency. Patients with LEP returning within 72 h (OR 1.19, 95% CI 1.01-1.40) and 7 days (OR 1.15, 95% CI 1.01-1.33) were more likely to be admitted to the hospital. CONCLUSIONS: After multivariable adjustment, we did not find an increased frequency of irregular ED departures or 72-h or 7-day returns among patients with LEP compared with people proficient in English. However, we did find that higher proportions of patients with LEP were admitted to the hospital at the time of the return ED visit.

Depression and Apathy across Different Variants of Progressive Supranuclear Palsy.

BACKGROUND: Apathy and depression commonly occur in patients with progressive supranuclear palsy (PSP)-Richardson's syndrome variant; depression often requiring treatment. Little is known, however, about apathy and depression among other PSP variants. METHODS: We prospectively studied 97 newly diagnosed PSP patients. All were classified into a PSP variant using the 2017 Movement Disorder Society-PSP criteria and administered the Geriatric Depression and Apathy Evaluation Scales. Differences in apathy and depression frequency and severity across six variants, and secondarily across PSP-Richardson's syndrome, PSP-Cortical and PSP-Subcortical, were analyzed using ANCOVA and linear regression adjusting for disease severity. RESULTS: Depression (55%) was more common than apathy (12%). PSP-Speech/Language (PSP-SL) variant had the lowest depression frequency (13%) and lower depression scores than the other variants. No differences in apathy frequency/severity were identified. CONCLUSION: PSP-SL patients may have less depression compared to PSP-Richardson's syndrome and other PSP variants.

Prediction of miscarriage and stillbirth at 11-13 weeks and the contribution of chorionic villus sampling.

OBJECTIVES: To derive models for estimating risk of miscarriage and stillbirth from maternal characteristics and findings of first-trimester screening for aneuploidies and to define the procedure-related risk of chorionic villus sampling (CVS) after adjusting for these factors. METHOD: We examined 33 856 singleton pregnancies at 11(+0) to 13(+6) weeks, and in 2396 CVS was carried out. Logistic regression analysis was used to examine the factors contributing to miscarriage and stillbirth. RESULTS: There were 33 310 (98.4%) livebirths, 404 (1.2%) miscarriages and 142 (0.4%) stillbirths. Models combining maternal characteristics, nuchal translucency, pregnancy-associated plasma protein-A (PAPP-A) and flow in the ductus venosus detected 36.9% of miscarriages and 35.2% of stillbirths, at a 10% false-positive rate. The risk of miscarriage and stillbirth increased with maternal age and weight, in women of African racial origin, in those with previous miscarriages or stillbirths and in those with low serum PAPP-A and reversed A-wave in the ductus venosus. The risk of miscarriage increased in women with pre-existing diabetes mellitus, in those conceiving on ovulation-induction drugs and in those with high fetal nuchal translucency, and the risk of stillbirth increased in women with chronic hypertension and in cigarette smokers. The expected number of miscarriages and stillbirths in the CVS group and the models derived from the non-CVS group were 45 (95% prediction intervals 32-58) and 18 (95% prediction intervals 9-26), respectively. These expected numbers were not significantly different from the observed 44 and 15 cases (p = 0.881 and 0.480), respectively. CONCLUSION: A high proportion of fetal losses can be predicted at 11 to 13 weeks. A model for such predictions can be used to assess the procedure-related risks from CVS.

Predictors of necrotizing enterocolitis in preterm growth-restricted neonates.

OBJECTIVE: The purpose of this study was to test the hypothesis that multivessel fetal Doppler imaging provides enhanced prediction of necrotizing enterocolitis (NEC) in preterm placental insufficiency. STUDY DESIGN: Placental-based growth-restricted fetuses (abdominal circumference <5%, abnormal umbilical artery [UA] Doppler imaging) were examined. UA, middle cerebral artery, ductus venosus, and umbilical vein (UV) were evaluated prenatally and were assessed for their ability to predict NEC in neonates who were delivered at <37 weeks of gestation. RESULTS: Thirty-nine of 404 neonates (9.7%) experienced NEC. Among these, the mortality rate was 15.4% (6/39 neonates; odds ratio, 2.7; 95% CI, 1.03-7.11). NEC cases had higher UA Doppler indices prenatally (P = .023), lower gestational ages and birthweight at delivery (P < .0001, respectively), 5-minute Apgar scores of <7, and higher umbilical cord artery base deficit (P < .01, respectively). NEC was more likely after prenatal UV pulsations (odds ratio, 2.4; 95% CI, 1.13-5.14; P = .028) and severe cardiovascular abnormality (composite variable incorporating UA- absent or reversed end diastolic velocity, absent or reversed ductus venosus a-wave, or UV pulsations; odds ratio, 2.1; 95% CI, 1.06-4.05; P = .029) Logistic regression revealed birthweight and base deficit as the main contributors of NEC (r(2) = 0.20; P < .0001). Receiver operating characteristic analyses revealed birthweight of <790 g (sensitivity, 74.4%; specificity, 72.9%; P < .0001) and gestational age of < or =32.2 weeks (sensitivity, 94.9%; specificity, 45.8%; P < .0001) as optimal cut-offs that provide an odds ratio for NEC of 8.2 (95% CI, 3.9-17.6; P < .0001). CONCLUSION: Placental disease predisposes the severely growth-restricted neonate to necrotizing enterocolitis. Even when arterial and venous Doppler variables are taken into consideration, birthweight remains the predominant risk factor for NEC. Further research should focus on the critical transition to neonatal life to identify relevant triggers in predisposed neonates.

Predictors of neonatal outcome in early-onset placental dysfunction.

OBJECTIVE: To identify specific estimates and predictors of neonatal morbidity and mortality in early onset fetal growth restriction due to placental dysfunction. METHODS: Prospective multicenter study of prenatally diagnosed growth-restricted liveborn neonates of less than 33 weeks of gestational age. Relationships between perinatal variables (arterial and venous Dopplers, gestational age, birth weight, acid-base status, and Apgar scores) and major neonatal complications, neonatal death, and intact survival were analyzed by logistic regression. Predictive cutoffs were determined by receiver operating characteristic curves. RESULTS: Major morbidity occurred in 35.9% of 604 neonates: bronchopulmonary dysplasia in 23.2% (n=140), intraventricular hemorrhage in 15.2% (n=92), and necrotizing enterocolitis in 12.4% (n=75). Total mortality was 21.5 % (n=130), and 58.3% survived without complication (n=352). From 24 to 32 weeks, major morbidity declined (56.6% to 10.5%), coinciding with survival that exceeded 50% after 26 weeks. Gestational age was the most significant determinant (P<.005) of total survival until 26(6/7) weeks (r(2)=0.27), and intact survival until 29(2/7) weeks (r(2)=0.42). Beyond these gestational-age cutoffs, and above birth weight of 600 g, ductus venosus Doppler and cord artery pH predicted neonatal mortality (P<.001, r(2)=0.38), and ductus venosus Doppler alone predicted intact survival (P<.001, r(2)=0.34). CONCLUSION: This study provides neonatal outcomes specific for early-onset placenta-based fetal growth restriction quantifying the impact of gestational age, birth weight, and fetal cardiovascular parameters. Early gestational age and birth weight are the primary quantifying parameters. Beyond these thresholds, ductus venosus Doppler parameters emerge as the primary cardiovascular factor in predicting neonatal outcome. LEVEL OF EVIDENCE: II.

PLUTO trial protocol: percutaneous shunting for lower urinary tract obstruction randomised controlled trial.

OBJECTIVES: The primary objective is to determine whether intrauterine vesicoamniotic shunting for fetal bladder outflow obstruction, compared with conservative, noninterventional care, improves prenatal and perinatal mortality and renal function. The secondary objectives are to determine if shunting for fetal bladder outflow obstruction improves perinatal morbidity, to determine if improvement in outcomes is related to prognostic assessment at diagnosis and, if possible, derive a prognostic risk index and to determine the safety and long-term efficacy of shunting. DESIGN: A multicentre randomised controlled trial (RCT). SETTING: Fetal medicine units. POPULATION: Pregnant women with singleton, male fetus with isolated lower urinary tract obstruction (LUTO). METHODS: Following ultrasound diagnosis of LUTO in a male fetus and exclusion of other structural and chromosomal anomalies, participation in the trial will be discussed with the mother and written information given. Consent for participation in the trial will be taken and the mother randomised via the internet to either insertion of a vesicoamniotic shunt or expectant management. During pregnancy, both groups will be followed with regular ultrasound scans looking at viability, renal measurements and amniotic fluid volume. Following delivery, babies will be followed up by paediatric nephrologists/urologists at 4-6 weeks, 12 months and 3 and 5 years to assess renal function via serum creatinine, renal ultrasound and need for dialysis/transplant. MAIN OUTCOME MEASURES: The main outcome measures will be perinatal mortality rates and renal function at 4-6 weeks and 12 months measured via serum creatinine, renal ultrasound and need for dialysis/transplant. FUNDING: Wellbeing of Women. ESTIMATED COMPLETION DATE: September 2010. TRIAL ALGORITHM: [flowchart: see text].

Monochorionic diamniotic twin pregnancy with selective IUGR type 2: fetoscopic and sonographic findings of ominous prognosis / Gestación gemelar monocorial complicada con RCIU selectiva tipo 2: hallazgos ecográficos y fetoscópicos de mal pronóstico

A woman with a monochorionic diamniotic twin pregnancy was referred to our Centre due to a discrepancy in size between the foetuses. She was 17 weeks' pregnant when the diagnosis of selective IUGR type 2 was made and the laser ablation of the placental anastomoses was performed. During the fetoscopy, we identified an arterio-venous anastomosis with bidirectional flow, which is atypical in this type of anastomoses (unidirectionals) and could represent a sign of ominous prognosis for the restricted twin.

Presentamos el caso de una gestante de 17 semanas con una gestación gemelar monocoriónica biamniótica complicada con RCIU selectivo tipo 2 que requirió, de acuerdo a criterios ecográficos, ablación quirúrgica láser de las anastomosis placentarias. Se identificó durante la fetoscopia una anastomosis arterio-venosa que mostraba flujo bidireccional lo cual es sumamente inusual en este tipo de anastomosis, no reportado antes en la literatura, constituyendo así un signo de mal pronóstico para el gemelo pequeño.
