RESUMEN

BACKGROUND: Fetal weight estimation at term is a challenging clinical task. OBJECTIVES: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies. METHODS: We conducted a single-center, retrospective cohort study (2006-2021) of women admitted in the first stage of labor or planned cesarean delivery. Complete blood counts were collected at admission. BW groups were categorized by weight (grams): < 2500 (group A), 2500-3499 (group B), 3500-4000 (group C), and > 4000 (group D). Two study periods were used to evaluate the association between WBC count and neonatal BW. RESULTS: There were a total of 98,632 deliveries. The dataset analyses showed a lower WBC count that was significantly and linearly associated with a higher BW; P for trend < 0.001 for women in labor. The most significant association was noted for the > 4000-gram newborns; adjusted odds ratio 0.97, 95% confidence interval 0.96-0.98; P < 0.001; adjusted for hemoglobin level, gestational age, and fetal sex. The 2018-2021 dataset analyses revealed WBC as an independent predictor of macrosomia with a significant incremental predictive value (P < 0.0001). The negative predictive value of the WBC count for macrosomia was significantly high, 93.85% for a threshold of WBC < 10.25 × 103/µl. CONCLUSIONS: WBC count should be considered to support the in-labor fetal weight estimation, especially valuable for the macrosomic fetus.

RESUMEN

Background and Aim: Polyhydramnios is associated with an increased risk of various adverse pregnancy outcomes, yet complications during labor have not been sufficiently studied. We assessed the labor and perinatal outcomes of idiopathic polyhydramnios during term labor. Methods: Retrospective cohort study at a tertiary medical center between 2010 and 2014. Women with idiopathic polyhydramnios defined as an amniotic fluid index (AFI) greater than 24 cm or a deep vertical pocket (DVP) > 8 cm (cases) were compared with women with a normal AFI (5-24 cm) (controls). Statistics: Descriptive, means ± SDs, medians + IQR. Comparisons: chi-square, Fisher's exact test, Mann-Whitney Test, multivariate logistic models. Results: During the study period 11,065 women had ultrasound evaluation completed by a sonographer within two weeks of delivery. After excluding pregnancies complicated by diabetes (pre-gestational or gestational), fetal anomalies, IUFD, multifetal pregnancies, elective cesarean deliveries (CD) or missing data, we included 750 cases and 7000 controls. The degree of polyhydramnios was mild in 559 (75.0%) cases (AFI 24-30 cm or DVP 8-12 cm), moderate in 137 (18.0%) cases (30-35 cm or DVP 12-15 cm) and severe in 54 (7.0%) cases (AFI >35 cm or DVP > 15 cm). Idiopathic polyhydramnios was associated with a higher rate of CD 9.3% vs. 6.2%, p = 0.004; a higher rate of macrosomia 22.8% vs. 7.0%, p < 0.0001; and a higher rate of neonatal respiratory complications 2.0% vs. 0.8%, p = 0.0001. A multivariate regression analysis demonstrated an independent relation between polyhydramnios and higher rates of CD, aOR 1.62 (CI 1.20-2.19 p = 0.002) and composite adverse neonatal outcome aOR 1.28 (CI 1.01-1.63 p = 0.043). Severity of polyhydramnios was significantly associated with higher rates of macrosomia and CD (p for trend <0.01 in both). Conclusions: The term idiopathic polyhydramnios is independently associated with macrosomia, CD and neonatal complications. The severity of polyhydramnios is also associated with macrosomia and CD.

RESUMEN

BACKGROUND: Acutely ill patients treated with blood transfusion (BT) have unfavorable prognoses. Nevertheless, data regarding outcomes in patients treated with BT admitted into a contemporary tertiary care medical center intensive cardiac care unit (ICCU) are limited. The current study aimed to assess the mortality rate and outcomes of patients treated with BT in a modern ICCU. METHODS: Prospective single center study where we evaluated mortality, in the short and long term, of patients treated with BT between the period of January 2020 and December 2021 in an ICCU. OUTCOMES: A total of 2132 consecutive patients were admitted to the ICCU during the study period and were followed-up for up to 2 years. In total, 108 (5%) patients were treated with BT (BT-group) during their admission, with 305 packed cell units. The mean age was 73.8 ± 14 years in the BT-group vs. 66.6 ± 16 years in the non-BT (NBT) group, p < 0.0001. Females were more likely to receive BT as compared with males (48.1% vs. 29.5%, respectively, p < 0.0001). The crude mortality rate was 29.6% in the BT-group and 9.2% in the NBT-group, p < 0.0001. Multivariate Cox analysis found that even one unit of BT was independently associated with more than two-fold the mortality rate [HR = 2.19 95% CI (1.47-3.62)] as compared with the NBT-group, p < 0.0001]. Receiver operating characteristic (ROC) curve was plotted for multivariable analysis and showed area under curve (AUC) of 0.8 [95% CI (0.760-0.852)]. CONCLUSIONS: BT continues to be a potent and independent predictor for both short- and long-term mortality even in a contemporary ICCU, despite the advanced technology, equipment and delivery of care. Further considerations for refining the strategy of BT administration in ICCU patients and guidelines for different subsets of high-risk patients may be warranted.

RESUMEN

BACKGROUND: Neonatal intensive care unit (NICU) admission among term neonates is a rare event. The aim of this study was to study the association of the NICU admission of term neonates on the risk of long-term childhood mortality. METHODS: A single-center case-control retrospective study between 2005 and 2019, including all in-hospital ≥ 37 weeks' gestation singleton live-born neonates. The center perinatal database was linked with the birth and death certificate registries of the Israeli Ministry of Internal Affairs. The primary aim of the study was to study the association between NICU admission and childhood mortality throughout a 15-year follow-up period. RESULTS: During the study period, 206,509 births were registered; 192,527 (93.22%) term neonates were included in the study; 5292 (2.75%) were admitted to NICU. Throughout the follow-up period, the mortality risk for term neonates admitted to the NICU remained elevated; hazard ratio (HR), 19.72 [14.66, 26.53], (p < 0.001). For all term neonates, the mortality rate was 0.16% (n = 311); 47.9% (n = 149) of those had records of a NICU admission. The mortality rate by time points (ratio1:10,0000 births) related to the age at death during the follow-up period was as follows: 29, up to 7 days; 20, 7-28 days; 37, 28 days to 6 months; 21, 6 months to 1 year; 19, 1-2 years; 9, 2-3 years; 10, 3-4 years; and 27, 4 years and more. Following the exclusion of congenital malformations and chromosomal abnormalities, NICU admission remained the most significant risk factor associated with mortality of the study population, HRs, 364.4 [145.3; 913.3] for mortality in the first 7 days of life; 19.6 [12.1; 32.0] for mortality from 28 days through 6 months of life and remained markedly elevated after age 4 years; HR, 7.1 [3.0; 17.0]. The mortality risk related to the NICU admission event, adjusted for admission diagnoses remained significant; HR = 8.21 [5.43; 12.4]. CONCLUSIONS: NICU admission for term neonates is a pondering event for the risk of long-term childhood mortality. This group of term neonates may benefit from focused health care.

RESUMEN

Background: Contrast computerized tomography (CT) scan is occasionally aborted due to a high coronary artery calcium score (CACS). For the same CACS in our clinical practice, we observed a higher occurrence of severe coronary artery disease (CAD) in patients with acute chest pain (ACP) compared to patients with stable chest pain (SCP). Since it is known that ACP differs in many ways from SCP, the aim of this study was to compare the predictive value of a high CACS for the diagnosis of severe CAD between ACP and SCP patients. Methods: This single center observational retrospective study included consecutive patients who underwent cardiac CT for chest pain and were found to have a CACS of >200 Agatston units. Patients were divided into two groups, ACP and SCP. Severe CAD was defined as ≥70% stenosis on coronary CT angiography or invasive coronary angiography. Baseline characteristics and final diagnosis of severe CAD were compared. Results: The cohort included 220 patients, 106 with ACP and 114 with SCP. ACP patients had higher severe CAD rates (60.4% vs. 36.8%; p < 0.001). On multivariate analysis including cardiac risk factors, CACS > 400 au (OR = 2.34 95% CI [1.32−4.15]; p = 0.004) and ACP (OR = 2.54 95% CI [1.45−4.45]; p = 0.001) were independent predictors of severe CAD. The addition of the clinical setting of ACP added significant incremental predictive value for severe stenosis. Conclusion: A high CACS is more associated with severe CAD in patients presenting with ACP than SCP. The findings suggest that the CACS could impact the management of patients during the scan.

RESUMEN

BACKGROUND: Women with inflammatory bowel diseases (IBD) often receive biologics to maintain remission during pregnancy. AIMS: To assess maternal and neonatal outcomes in patients with IBD treated with ustekinumab (UST) during pregnancy METHODS: In a multicentre, prospective cohort study, we recruited women with IBD treated with UST during pregnancy between 2019 and 2021. Outcomes were compared among patients treated with UST, anti-tumour necrosis factor α, (anti-TNF) and non-UST, non-anti-TNF therapies. UST-treated patients were matched 1:2 to controls according to age, body mass index and parity. Newborns were followed up to 12 months. RESULTS: We recruited 129 pregnant patients: UST 27; anti-TNF 52; non-UST, non-anti-TNF 50 (thiopurine or mesalazine 30, no therapy 20); Crohn's disease 25 (96.9%). Overall, pregnancy, neonatal and newborn outcomes were satisfactory, with no significant differences among patients treated with UST, anti-TNF and non-UST non-anti-TNF agents for obstetrical maternal complications [UST 3 (11.5%), anti TNF 12 (23.1%), non UST, non-anti-TNF 4 (8.2%), p = 0.095], pre-term delivery [1 (4.3%), 9 (18.4%), 4 (5.7%), p = 0.133], low birth weight [1 (4.2%), 5 (10.2%), 4 (8.3%), p = 0.679], or first year newborn hospitalisation [2 (9.1%), 4 (8.2%), 3 (6.1%), p = 0.885]. CONCLUSION: Pregnant patients with IBD treated with UST demonstrated favourable pregnancy and neonatal outcomes that were comparable with those in patients treated with anti-TNF or other therapy. Data are reassuring for patients with IBD and their physicians when considering UST during pregnancy.

RESUMEN

INTRODUCTION: D-dimer is a small protein fragment produced during fibrinolysis. High D-dimer levels were shown to have prognostic impact in critically ill patients. Nevertheless, data regarding D-dimer's prognostic impact among tertiary care intensive coronary care unit (ICCU) patients is scarce. MATERIAL AND METHOD: All patients admitted to the ICCU between 1-12/2020 were prospectively included. Based on admission D-dimer level, patients were categorized into low and high D-dimer groups (< 500 ng/ml and ≥ 500 ng/ml) and also to age-adjusted D-dimer cutoff (500 ng/ml for ages ≤ 50 years old and age*10 for ages>50 years old). RESULTS AND DISCUSSION: A total of 959 consecutive patients were included, including 296 (27.4%) and 663 (61.3%) patients with low and high D-Dimer levels, respectively. Patients with high D-dimer level were older compared with patients with low D-dimer level (age 70.4 ± 15 and 59 ± 13 years, p = 0.004) and had more comorbidities. The most common primary diagnosis on admission among the low D-dimer group was acute coronary syndrome (ACS) (74.3%), while in the high D-dimer group it was a combination of ACS (33.6%), cardiac structural interventions (26.7%) and various arrhythmias (21.1%). High D-dimer levels were associated with increased mortality rate, even after adjustment for age, gender, comorbidities and left ventricular ejection fraction (LVEF). High D-dimer levels were independently associated with increased overall 1-year mortality rate (HR = 5.8; 95% CI; 1.7-19.1; p = 0.004). CONCLUSION: Elevated D-dimer levels on admission in ICCU patients is an independently poor prognostic factor for in-hospital morbidity and 1-year overall mortality rate following hospitalization.

RESUMEN

Objective: Neonatal intensive care unit (NICU) admission among term neonates is associated with significant morbidity and mortality, as well as high healthcare costs. A comprehensive NICU admission risk assessment using an integrated statistical approach for this rare admission event may be used to build a risk calculation algorithm for this group of neonates prior to delivery. Methods: A single-center case−control retrospective study was conducted between August 2005 and December 2019, including in-hospital singleton live born neonates, born at ≥37 weeks' gestation. Analyses included univariate and multivariable models combined with the machine learning gradient-boosting model (GBM). The primary aim of the study was to identify and quantify risk factors and causes of NICU admission of term neonates. Results: During the study period, 206,509 births were registered at the Shaare Zedek Medical Center. After applying the study exclusion criteria, 192,527 term neonates were included in the study; 5292 (2.75%) were admitted to the NICU. The NICU admission risk was significantly higher (ORs [95%CIs]) for offspring of nulliparous women (1.19 [1.07, 1.33]), those with diabetes mellitus or hypertensive complications of pregnancy (2.52 [2.09, 3.03] and 1.28 [1.02, 1.60] respectively), and for those born during the 37th week of gestation (2.99 [2.63, 3.41]; p < 0.001 for all), adjusted for congenital malformations and genetic syndromes. A GBM to predict NICU admission applied to data prior to delivery showed an area under the receiver operating characteristic curve of 0.750 (95%CI 0.743−0.757) and classified 27% as high risk and 73% as low risk. This risk stratification was significantly associated with adverse maternal and neonatal outcomes. Conclusion: The present study identified NICU admission risk factors for term neonates; along with the machine learning ranking of the risk factors, the highly predictive model may serve as a basis for individual risk calculation algorithm prior to delivery. We suggest that in the future, this type of planning of the delivery will serve different health systems, in both high- and low-resource environments, along with the NICU admission or transfer policy.

RESUMEN

Objective: To investigate the impact of parity-customized versus population-based birth weight charts on the identification of neonatal risk for adverse outcomes in small (SGA) or large for gestational age (LGA) infants compared to appropriate for gestational age (AGA) infants. Study design: Observational, retrospective, cohort study based on electronic medical birth records at a single center between 2006 and 2017. Neonates were categorized by birth weight (BW) as SGA, LGA, or AGA, with the 10th and 90th centiles as boundaries for AGA in a standard population-based model adjusted for gestational age and gender only (POP) and a customized model adjusted for gestational age, gender, and parity (CUST). Neonates defined as SGA or LGA by one standard and not overlapping the other, are SGA/LGA CUST/POP ONLY. Analyses used a reference group of BW between the 25th and 75th centile for the population. Results: Overall 132,815 singleton, live, term neonates born to mothers with uncomplicated pregnancies were included. The customized model identified 53% more neonates as SGA-CUST ONLY who had significantly higher rates of morbidity and mortality compared to the reference group (OR = 1.33 95% CI [1.16−1.53]; p < 0.0001). Neonates defined as LGA by the customized model (LGA-CUST) and AGA by the population-based model LGA-CUST ONLY had a significantly higher risk for morbidity compared to the reference (OR = 1.36 95% CI [1.09−1.71]; p = 0.007) or the LGA POP group. Neonatal mortality only occurred in the SGA and AGA groups. Conclusions: The application of a parity-customized only birth weight chart in a population of singleton, term neonates is a simple platform to better identify birth weight related neonatal risk for morbidity and mortality.

RESUMEN

RESEARCH QUESTION: Is extended fertility at the advanced reproductive age of 43-47 years associated with high anti-Müllerian hormone (AMH) concentrations? DESIGN: Prospective cohort study including 98 women aged 43-47 years old with a spontaneous conception who were tested for AMH concentrations 1-4 days and 3-11 months post-partum. AMH concentrations at 3-11 months post-partum were further compared with AMH concentrations in healthy age-matched controls that last gave birth at ≤42 years old. Women with current use of combined hormonal contraceptives (CHC), ovarian insult or polycystic ovary syndrome were excluded. Power analysis supported the number of participating women. RESULTS: Median AMH concentrations did not differ between the extended fertility (n = 40) and control (n = 58) groups (0.50 versus 0.45 ng/ml, P = 0.51). This remained when analysing by age (≥ or <45 years old). AMH concentrations and women's age did not correlate within the extended fertility group (r = 0.017, P = 0.92); a weak negative correlation was found within the control group (r = -0.23, P = 0.08). AMH was significantly higher 3-11 months post-partum (0.50 ng/ml [0.21-1.23]) than 1-4 days post-partum (0.18 ng/ml [0.06-0.40]), P < 0.001. The two results for each participant were highly correlated (r = 0.82, P < 0.001). The extended fertility and control groups were similar regarding age, age at menarche, past CHC use and history of fertility concern. Parity differed but showed no significant correlation with AMH. CONCLUSIONS: Serum AMH concentrations that reflect ovarian reserve do not seem to predict reproductive potential at highly advanced age. Thus, additional factors such as oocyte quality should also be considered in evaluating reproductive potential. AMH suppression that is associated with pregnancy at 1-4 days post-partum recovers at 3-11 months post-partum in women of highly advanced reproductive age.

RESUMEN

BACKGROUND: Hemoglobin A1C (HbA1c) is a form of glycated hemoglobin used to estimate glycemic control in diabetic patients. Data regarding the prognostic significance of HbA1c levels in contemporary intensive cardiac care unit (ICCU) patients is limited. METHODS: All patients admitted to the ICCU at a tertiary care medical center between January 1, 2020, and June 30, 2021, with documented admission HbA1c levels were included in the study. Patients were divided into 3 groups according to their HbA1c levels: < 5.7 g% [no diabetes mellitus (DM)], 5.7-6.4 g% (pre-DM), ≥ 6.5 g% (DM). RESULTS: A total of 1412 patients were included. Of them, 974 (69%) were male with a mean age of 67(± 15.7) years old. HbA1c level < 5.7 g% was found in 550 (39%) patients, 5.7-6.4 g% in 458 (32.4%) patients and ≥ 6.5 g% in 404 (28.6%) patients. Among patients who did not know they had DM, 81 (9.3%) patients had high HbA1c levels (≥ 6.5 g%) on admission. The crude mortality rate at follow-up (up to 1.5 years) was almost twice as high among patients with pre-DM and DM than in patients with no DM (10.6% vs. 5.4%, respectively, p = 0.01). Interestingly, although not statistically significant, the trend was that pre-DM patients had the strongest association with mortality rate [HR 1.83, (95% CI 0.936-3.588); p = 0.077]. CONCLUSIONS: Although an HbA1c level of ≥ 5.7 g% (pre-DM & DM) is associated with a worse prognosis in patients admitted to ICCU, pre-DM patients, paradoxically, have the highest risk for short and long-term mortality rates.

RESUMEN

Patients with ST-elevation myocardial infarction (STEMI) can present with angiographically significant coronary artery disease (CAD) of non-infarct-related artery (IRA) or with IRA-only CAD. This study aimed to evaluate the prevalence, predictors, and outcome of patients with STEMI and angiographically significant CAD of non-IRA. All consecutive patients with STEMI who underwent primary percutaneous coronary intervention between 2000 and 2020 were included. Angiographically significant CAD was defined as >50% stenosis of the left main coronary artery and/or >90% stenosis for all other coronary arteries. A total of 2,663 patients had IRA-only CAD (80.2%) and 657 had angiographically significant non-IRA CAD (19.8%). Independent predictors for non-IRA CAD were male gender (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.05 to 1.70, p = 0.021), age >50 years (OR 1.45, 95% CI 1.11 to 1.91, p = 0.007), and diabetes mellitus (OR 1.56, 95% CI 1.29 to 1.9, p <0.001), whereas smoking (OR 0.83, 95% CI 0.68 to 0.99, p = 0.004) and family history of CAD (OR 0.78, 95% CI 0.62 to 0.98, p = 0.032) were found to be negatively associated with non-IRA CAD. In-hospital 30-day and 1- and 5-year all-cause mortality were higher in patients with non-IRA CAD compared with IRA-only CAD (5.8% vs 2.5%, 8.5% vs 3.3%, 18.4% vs 7.6% and 36.3% vs 20.3%, respectively; p for all <0.001). In conclusion, 20% of patients with STEMI had angiographically significant non-IRA CAD. Older age, male gender, and diabetes mellitus were independent predictors for non-IRA CAD, whereas smoking and family history of CAD predicted IRA-only CAD. The presence of non-IRA CAD was associated with higher short- and long-term all-cause mortality rates.

RESUMEN

Background: Heart failure (HF) patients with wide QRS often benefit from cardiac resynchronization therapy (CRT), although QRS narrowing does not always occur. The current study investigates the incidence and predictors for QRS narrowing following CRT and its long-term impact on clinical outcomes. Methods: Among individuals undergoing clinically indicated CRT, pre-and post-implantation electrocardiographs were meticulously analyzed for QRS duration change. All-cause mortality and the composite of mortality and HF hospitalizations were retrieved. Results: For 104 patients, mean age 67 years, 25% females, QRS narrowed within days by 20.2 ± 24.7 ms. In 55/104 (53%) QRS narrowed by ≥20 ms ("acute narrowing"). Female gender and baseline QRS predicted acute narrowing. Acute narrowing persisted for 1−6 weeks in 18/20 (90%) and 3−12 months in 21/31 (68%) of patients. During the average follow-up of 41 months, 29/104 (28%) died and 50/104 (48%) met the composite outcome. In a multivariable analysis including comorbidities and cardiac history, prolonged baseline PR interval (HR 1.015, CI 1.008−1.021, p < 0.001) and acute narrowing < 20 ms (HR 3.243, CI 1.593−6.603, p = 0.001) were significant and independent predictors for the composite outcome. Conclusions: Post-CRT acute QRS narrowing ≥ 20 ms is independently associated with favorable long-term outcomes and might be considered as a novel measure for procedural success.

RESUMEN

BACKGROUND: Neonatal jaundice occurs in approximately 60% of term newborns. Although risk factors for neonatal jaundice have been studied, all the suggested strategies are based on various newborn tests for bilirubin levels. We aim to stratify neonates into risk groups for clinically significant neonatal jaundice using a combined data analysis approach, without serum bilirubin evaluation. STUDY DESIGN: Term (gestational week 37-42) neonates born in a single medical center, 2005-2018 were identified. Anonymized data were analyzed using machine learning. Thresholds for stratification into risk groups were established. Associations were evaluated statistically using neonates with and without clinically significant neonatal jaundice from the study population. RESULTS: A total of 147,667 consecutive term live neonates were included. The machine learning diagnostic ability to evaluate the risk for neonatal jaundice was 0.748; 95% CI 0.743-0.754 (AUC). The most important factors were (in order of importance) maternal blood type, maternal age, gestational age at delivery, estimated birth weight, parity, CBC at admission, and maternal blood pressure at admission. Neonates were then stratified by risk: 61% (n = 90,140) were classed as low-risk, 39% (n = 57,527) as higher-risk. Prevalence of jaundice was 4.14% in the full cohort, and 1.47% and 8.29% in the low- and high-risk cohorts, respectively; OR 6.06 (CI: 5.7-6.45) for neonatal jaundice in high-risk group. CONCLUSION: A population tailored "first step" screening policy using machine learning model presents potential of neonatal jaundice risk stratification for term neonates. Future development and validation of this computational model are warranted.

RESUMEN

OBJECTIVE: Fetal growth restriction is suspected when the estimated fetal weight is <10th percentile for gestational age. Using a regional sonographic estimated fetal weight growth curve to diagnose fetal growth restriction has no known benefits; however, the traditional approach of using birthweight curves is misleading, since a large proportion of preterm births arise from pathological pregnancies. Our aim was to compare the diagnostic accuracies of sonographic versus birthweight curves in diagnosing fetal growth restriction. Our secondary aim was to compare maternal, fetal and neonatal outcome based on these two approaches. METHODS: Retrospective study based on computerized medical records. Included were women with a singleton pregnancy, that underwent fetal biometry between 24 and 36.6 weeks' gestation (January 2010-February 2016) and delivered in our center. Each pregnancy was assigned to one of three groups based on the earliest sonographic estimated fetal weight performed: G1-Appropriate for gestational age, G2-fetal growth restriction based on sonographic but not birthweight curves; or G3-fetal growth restriction based on birthweight growth curves. Demographics, obstetric characteristics, ultrasound data, and neonatal data were retrieved and compared between groups. Primary outcome: rate of small for gestational age neonates in each group. Secondary outcomes were various adverse maternal and neonatal outcomes. RESULTS: Six thousand and five pregnancies met inclusion criteria. Of these 5386 (89.6%) were categorized as G1, 300 (5%) as G2 and 319 (5.3%) as G3. The rate of small for gestational age neonates differed significantly between groups: G1 9.2%, G2 39.7% and G3 70%. Multivariable logistic regression modeling reiterated these rates: the odds ratios for small for gestational age were 6.47 [95% CI 4.99-8.40] and 23.99 [95% CI 18.26-31.51] for G2 and G3 respectively. Prediction of small for gestational age based on sonographic EFW curves increased the sensitivity for detection of SGA from 26% to 41% with a slight decrease in specificity from 98% to 95%, and a decrease of the positive likelihood ratio from 18.4 to 7.7, however there was no significant change in the overall test accurcy; 88.5% to 87.1%.Secondary outcomes also differed between groups: G2 and G3 had similar rates of maternal and neonatal morbidities and most parameters were higher than G1. G2 and G3 showed lower mean gestational age at delivery (36.2 weeks and 35.9 weeks vs.37.8; p < .0001), and higher rates of preterm delivery (40% and 51.7% vs. 21.5%; p < .001), as well as higher rates of intrauterine fetal demise 3% in G2, 6.9% in G3 and 0.9% in G1, p < .0001. CONCLUSION: Pregnancies that are currently managed as appropriate for gestational age based on birthweight curves, but classified as growth restricted when prenatal sonographic curves are used, are associated with higher rates of small for gestational age and poor perinatal outcomes, at rates comparable to pregnancies that are classified as growth restricted based on birthweight curves. Furthermore, applying sonographic curves increases the sensitivity for detection of small for gestational age neonates. Consequently, consideration should be given to the use of sonographic biometry curves for defining fetal growth restriction.

RESUMEN

Introduction: Hypoalbuminemia is common in acute and chronic diseases. It has been proposed as a potential biomarker of frailty, which itself is associated with worse outcomes. However, data regarding the level of hypoalbuminemia and its prognosis in contemporary intensive coronary care unit (ICCU) patients is scarce. Materials and Methods: All patients who had albumin level on admission to an ICCU at a tertiary care center between January 1, 2020, and December 31, 2020, were included in the study. Patients were divided into 3 groups according to their albumin level on admission: low (< 3 g/dL), intermediate (3 g/dL≤ and ≤ 4 g/dL) and high albumin level (> 4 g/dL). Survival and in-hospital interventions and complications were compared. Results: Overall 1,036 consecutive patients were included, mean age was 67±16 years and 70% were males. Of them 88 (8.5%) had low, 739 (71.5%) intermediate and 209 (20%) had high albumin levels. In a multivariate cox proportional hazards analysis, low albumin level was independently associated with higher 1-year mortality rate as compared with high albumin level (HR=9.5; 95% CI: 3.2-25.5, p<0.001). Intermediate albumin level had also a trend toward higher 1-year mortality rate as compared with high albumin level (HR=2.1; 95% CI: 0.9-5.6, p=0.09). Conclusion: Hypoalbuminemia in ICCU patients is a poor prognostic factor associated with in-hospital complications and an independent risk factor for 1-year mortality rate, while intermediate albumin level shows a trend towards higher 1-year mortality rate as well.

RESUMEN

AIM: Evaluate prevalence of heart failure (HF) medications and their association with ventricular arrhythmia (VA) and survival among patients implanted with primary prevention implantable cardiac defibrillator (ICD)/cardiac resynchronization therapy + defibrillator (CRTD) devices. METHODS: Association of treatment and dose (% guideline recommended target) of beta-adrenergic receptor antagonist (BB), angiotensin-antagonists (AngA), and mineralocorticoid-antagonists (MRA), after ICD/CRTD implant with VA and mortality was retrospectively analyzed. RESULTS: Study included 186 HF patients; 42.5% and 57.5% implanted with ICD and CRTD, respectively. During 3.8 (2.1;6.7) years; 52 (28%) had VA and 77 (41.4%) died. Treatment (% of patients) included: BB (83%), AngA (87%), and MRA (59%). Median doses were 25(12.5;50)% of target for all medications. BB treatment >25% target dose was associated with reduced VA incidence. In the multivariable model including age, gender, diabetes, heart rate, and medication doses, increased BB dose was associated with reduced VA (hazard ratio (HR) 0.443 95% CI 0.222-0.885; p = 0.021). In the multivariable model for overall mortality including age, gender, renal disease, VA, and medical treatment, VA was associated with increased mortality (HR 2.672; 95% CI 1.429-4.999; p = 0.002) and AngA treatment was associated with reduced mortality (HR 0.515; 95% CI 0.285-0.929; p = 0.028). CONCLUSIONS: In this cohort of real-life HF patients discharged after ICD/CRTD implant, prevalence of guideline-based HF medications was high, albeit with low doses. Higher BB dose was associated with reduced VA, while AngA was associated with improved survival.

RESUMEN

OBJECTIVES: Investigate the association between maternal leukocyte count at admission for labor and postpartum infectious maternal morbidity (PPIM) following vaginal delivery. STUDY DESIGN: Retrospective cohort study, 2005-2017. Afebrile women, term, singleton, vaginal delivery included. Maternal leukocyte/differential at admission for labor and 24 h postpartum were analyzed as continuous values and quintiles. Pre/postpartum difference (Δleukocyte) was calculated. The primary outcome was maternal PPIM, early and late. The secondary outcome was adverse neonatal outcomes (ANO). RESULTS: 58,174 eligible deliveries out of168,979 (34.4 %); 1068 (1.8 %) women with PPIM. The rate rose linearly from 1.4 % for the lowest admission for labor leukocyte quantile to 2.7 % for the highest quantile, p for trend <0.001. The women with early PPIM had significantly higher admission levels of leukocytes (mean): 12.04 ± 3.43 vs. 11.18 ± 2.86 × 10^3/µl; neutrophils, 9.48 ± 3.46 vs. 8.40 ± 2.67 × 10^3/µl; and monocytes 0.76 ± 0.25 vs. 0.72 ± 0.23 × 10^3/µl); p < 0.001 for all. The mean leukocyte count for women with PPIM diagnosis, including only postpartum fever, was 12.06 ± 2.64; significantly higher than in the non-PPIM group, p = 0.014. A Δleukocyte value of >3.7 × 10^3/µl is significantly associated with PPIM, aOR 2.10 [1.82-2.41]. No significant association between leukocyte count or Δleukocyte and maternal readmission rate due to infectious complications. 386 neonates (0.7 %) had records of ANO and 64 neonates (0.1 %) had records of neonatal sepsis, positive linear association; p for trend < 0.001. The maternal Δleukocyte value of >3.7 × 10^3/µl was found to be significantly associated with the risk for ANO, aOR 1.5[1.19-1.90]. CONCLUSION: In healthy women, an elevated level of the leukocyte count at admission for labor and the Δleukocyte are significant risk predictors of PPIM and ANO.

RESUMEN

Objective: To assess the maternal and neonatal outcomes following delayed diagnosis of uterine rupture (diagnosis during the early postpartum period) in comparison to women with an intrapartum diagnosis of uterine rupture.Methods: Retrospective study of electronic medical records (EMR) from 2005 to 2018 in a single large academic tertiary care. Demographic, obstetric and maternal characteristics and outcomes were retrieved and compared. Univariate, followed by multivariate analyses were applied to evaluate the association between maternal and neonatal outcomes. Only complete uterine ruptures were included. The primary outcome of this study was defined as hysterectomy rates. Secondary outcomes were maternal and neonatal morbidity parameters.Results: During the study period, 143 parturients with uterine rupture were identified from 174,189 deliveries (0.08%). Of these, 29 (20.3%) had delayed diagnosis with a median time from delivery to the operation of 4.5 hours (IQR 0.83-28 hours). Factors that were identified as independent risk factors for delayed diagnosis: an unscarred uterus (aOR 27.0, 95% CI 6.58-111.1), epidural analgesia during labor (aOR 7.9, 95% CI 2.32-27.05) and grand-multiparity (aOR 4.6, 95% CI 1.40-14.99). Maternal outcomes demonstrated that parturients with a delayed diagnosis had significantly higher rates of blood transfusions, puerperal fever, and hysterectomy (p<.001 for all). In a multivariate model, the delayed diagnosis was found to be independently associated with hysterectomy (aOR 4.90, 95% CI 1.28-19.40). There were no differences regarding to neonatal outcomes.Conclusion: Parturients with delayed diagnosis of uterine rupture have unique characteristics and poorer maternal outcomes. It is possible that awareness of this population will enable earlier diagnosis and may help improve outcomes.

RESUMEN

INTRODUCTION: Intraperitoneal closed suction drains are occasionally placed during cesarean delivery. This study aims to ascertain the prevalence, associated factors, outcome, and risks of intraperitoneal closed-suction drain placed during cesarean delivery. MATERIAL AND METHODS: A retrospective cohort study of all women undergoing cesarean delivery in a single center from 2005 to 2015. We excluded cases of cesarean hysterectomy and women who had hollow viscus injury. Cesarean deliveries were categorized into two groups based on intraperitoneal drain use: drain + and drain-.The study aims were to describe: (1) drain use prevalence; (2) factors associated with drain use; (3) interval to relaparotomy due to intraperitoneal bleeding and outcome of drain use; and (4) unique drain-related adverse outcome. Statistics: univariate, multivariable, and inverse probability treatment weighting (IPTW) analysis. RESULTS: After applying the inclusion and exclusion criteria, 16 581 (99.3%) cesareans were included. An intraperitoneal drain was used in 1264 (7.6%) cesareans, ranging from 4.4 to 18.8% in women with no and four or more cesareans, respectively. Comparing the drain + and drain- groups, multivariable analysis revealed that the factors associated with the use of a drain included (OR, 95%CI) uterine rupture (5.14, 3.15-8.38), intrapartum fever (2.65, 1.87-3.75), previous cesareans (2.29, 2.00-2.68), second-stage cesarean (2.21, 1.64-2.74), preterm delivery (1.89, 1.63-2.19), spontaneous onset of labor (1.42, 1.24-1.63), and maternal age greater than 35 years (1.35, 1.19-1.54); p < .001 for all. Of the forty-four women (0.27%) who underwent relaparotomy for intraperitoneal bleeding, there were fourteen in the intraperitoneal drain group. Inverse probability treatment weighting analysis demonstrated that median (interquartile range) times (hours) to relaparotomy were significantly shorter in the drain + group [3.5 (3.3-10.0) versus 12.5 (7.9-15.6), p < .001] and that puerperal fever incidence was higher in the drain + group (2.2 vs. 1.4%, p < .001). The incidence of relaparotomy to remove a retained drain or drain fragment was 0.48% (6/1264). CONCLUSIONS: Drain use in our study resulted in a shorter time to relaparotomy for intraperitoneal hemorrhage. However, it was associated with a higher risk for puerperal fever and a 0.5% risk for relaparotomy for removal of the drain.KEY MESSAGEIntraperitoneal drain placed during cesarean is used more often in complicated surgeries and is associated with a shorter interval to relaparotomy.
