Risk Factors for Carbetocin Failure after a Cesarean Section: Is Obesity One of Them?

Obese pregnant women have increased rates of fetal macrosomia, long labor, and cesarean sections, which lead to an increased risk of postpartum hemorrhage (PPH). Carbetocin is useful for the prevention of PPH after a cesarean section. Our study aimed to investigate predictors of carbetocin failure after a cesarean section, and specifically whether obesity is associated with carbetocin failure. We retrospectively analyzed all women who received carbetocin after a cesarean section. Carbetocin failure was defined as changes in hematocrit and hemoglobin, blood loss ≥ 1000 mL, and the need for an additional uterotonic agent or second-line therapies for persistent PPH. Univariate and multivariate analyses were performed to investigate predictors of carbetocin failure. The study included 600 women, with 131 (21.8%) obese women. Overall, 44 (7.3%) carbetocin failures were reported, and rates of obese women were similar between groups (carbetocin failure, 11.4% vs. 22.9%; p = 0.08). Previous PPH (p < 0.001), a cesarean section during labor (p = 0.01), cervical ripening (p = 0.02), and birthweight (p = 0.01) were significantly different between groups. In the multivariable logistic regression analysis adjusted for potential confounders, cervical ripening (adjusted odds ratio (OR) 2.23, 95% confidence interval (CI) 1.01–4.80), compared with spontaneous labor, was significantly associated with carbetocin failure. Obesity was not associated with carbetocin failure after cesarean sections.

AbstractObjective:To evaluate delivery management and outcomes in fetuses prenatally diagnosed with CHD.Study design:A retrospective cohort study was conducted on 6194 fetuses (born between 2013 and 2016), comparing prenatally diagnosed with CHD (170) to those with non-cardiac (234) and no anomalies (5790). Primary outcomes included the incidence of preterm delivery and mode of delivery.Results:Gestational age at delivery was significantly lower between the CHD and non-anomalous cohorts (38.6 and 39.1 weeks, respectively). Neonates with CHD had a significantly lower birth weights (p < 0.001). There was an approximately 1.5-fold increase in the rate of primary cesarean sections associated with prenatally diagnosed CHD with an odds ratio of 1.49 (95% CI 1.06–2.10).Conclusions:Our study provides additional evidence that the prenatal diagnosis of CHD is associated with a lower birth weight, preterm delivery, and with an increased risk of delivery by primary cesarean section.

Background: Numerous studies have reported that shorter time to first cigarette (TTFC) is linked to elevated risk for smoking-related morbidity. However, little is known about the influence of early TTFC on self-reported health among current smokers. Hence, the objective of this study was to examine the association between TTFC and self-reported health among US adult smokers. Methods: Data came from the 2012-2013 National Adult Tobacco Survey (NATS). Current smokers aged 18 years and older (N = 3323) were categorized into 2 groups based on TTFC: ≤ 5 minutes (n = 1066) and >5 minutes (n = 2257). Propensity score matching (PSM) was used to control selection bias. Results: After adjusting for sociodemographic and smoking behavior factors, current smokers with early TTFC had higher odds for poor health in comparison with current smokers with late TTFC in the prematching (adjusted odds ratio [AOR] = 1.65; 95% confidence interval [CI] = 1.31-2.08) and postmatching (AOR = 1.60; 95% CI = 1.22-2.09) samples. Conclusions: In conclusion, smokers with early TTFC were associated with increased risk of poor health in the United States. To reduce early TTFC, elaborate efforts are needed to educate people about harms of early TTFC and benefits of stopping early TTFC.

The Relationship

Introduction: Infection has been described as a trigger for acute ischemic stroke, but the relationship between postoperative infection and the risk of postoperative stroke is unclear. We investigated the association between postoperative infection and stroke using the American College of Surgeons National Surgical Quality Initiative Program (NSQIP) database. Hypothesis: Postoperative infection is associated with an increased risk of postoperative stroke. Methods: We used the NSQIP database to identify all patients who underwent surgery between the years of 2000 and 2010 and developed a postoperative stroke within 30 days of surgery. The group was further stratified according to the presence of infection preceding stroke. Using a logistic regression model adjusted for age, race, sex, medical comorbidities, surgical type, and dichotomized functional status, we compared the risk of stroke in patients with and without preceding infections, and investigated the risk of infection following stroke. Results: 729,886 surgical patients were identified, of whom 2,703 (0.3%) developed postoperative stroke. 848 (0.12%) patients developed both postoperative stroke and infection. Among patients who had postoperative stroke, 100 (3.7%) had developed an infection prior to developing a stroke. Patients with infection prior to stroke had a lower risk of stroke than patients who did not develop infection prior to stroke (adjusted odds ratio [OR] 0.25, 95%CI 0.20-0.32). 748 patients (0.1%) developed an infection after having a postoperative stroke. These patients had a higher risk of infection (incidence rate ratio 2.76, 95%CI 2.57-2.97) and a higher odds of infection (adjusted odds ratio [OR] 3.47, 95%CI 3.18-3.78) than patients who did not have a stroke. Conclusions: We found that the presence of a preceding infection was associated with a low risk of postoperative stroke in a large surgical inpatient sample. Although the total number of strokes may have been under-reported, these results conflict with other studies that report that infection is a trigger for ischemic stroke. Further analyses using more granular data are needed to investigate the relationship between postoperative infection and the risk of postoperative stroke.

Background Some psychiatric disorders have been associated with increased risk of miscarriage. However, there is a lack of studies considering a broader spectrum of psychiatric disorders to clarify the role of common as opposed to independent mechanisms. Aims To examine the risk of miscarriage among women diagnosed with psychiatric conditions. Method We studied registered pregnancies in Norway between 2010 and 2016 (n = 593 009). The birth registry captures pregnancies ending in gestational week 12 or later, and the patient and general practitioner databases were used to identify miscarriages and induced abortions before 12 gestational weeks. Odds ratios of miscarriage according to 12 psychiatric diagnoses were calculated by logistic regression. Miscarriage risk was increased among women with bipolar disorders (adjusted odds ratio 1.35, 95% CI 1.26–1.44), personality disorders (adjusted odds ratio 1.32, 95% CI 1.12–1.55), attention-deficit hyperactivity disorder (adjusted odds ratio 1.27, 95% CI 1.21–1.33), conduct disorders (1.21, 95% CI 1.01, 1.46), anxiety disorders (adjusted odds ratio 1.25, 95% CI 1.23–1.28), depressive disorders (adjusted odds ratio 1.25, 95% CI 1.23–1.27), somatoform disorders (adjusted odds ratio 1.18, 95% CI 1.07–1.31) and eating disorders (adjusted odds ratio 1.14, 95% CI 1.08–1.22). The miscarriage risk was further increased among women with more than one psychiatric diagnosis. Our findings were robust to adjustment for other psychiatric diagnoses, chronic somatic disorders and substance use disorders. After mutual adjustment for co-occurring psychiatric disorders, we also observed a modest increased risk among women with schizophrenia spectrum disorders (adjusted odds ratio 1.22, 95% CI 1.03–1.44). Conclusions A wide range of psychiatric disorders were associated with increased risk of miscarriage. The heightened risk of miscarriage among women diagnosed with psychiatric disorders highlights the need for awareness and surveillance of this risk group in antenatal care.

Background: A previous SAMMPRIS analysis of patients randomized to stenting showed that peri-procedural ischemic infarcts were significantly associated with diabetes, basilar stenosis, age, and smoking status with never smokers having a higher risk (odds ratio = 8.8, p< 0.001). We sought to determine if this finding could be due to a higher burden of other risk factors in never smokers. Method: Baseline features in 213 patients undergoing stenting in SAMMPRIS were compared between never smokers vs. former and current smokers in univariate and multivariate analyses. Logistic regression was used to determine the effect of smoking on peri-procedural ischemic infarcts after adjusting for factors related to smoking. Data: Univariate results are shown in Table 1. Never smokers were significantly (P<0.05) more likely to be female, diabetic, hypertensive, and have another intracranial stenosis, but in multivariate analyses only hypertension and another intracranial stenosis remained significantly (P<0.05) associated with smoking status. In a multivariate model that incorporated hypertension and another intracranial stenosis along with smoking status, diabetes, basilar stenosis, and age, smoking status remained significant with an increased risk among patients who never smoked (odds ratio = 5.3, p = 0.005). Conclusion: While never smokers had significantly higher rates of some risk factors compared to active or previous smokers, these risk factors do not explain all the increased risk of early stroke in never smokers after stenting in SAMMPRIS. Another contributory factor may be that smoking accelerates the conversion of clopidogrel to its active form.

Background and Purpose: Symptomatic hemorrhage contributes to an increased risk of repeated bleeding and morbidity in cerebral cavernous malformation (CCM). A better understanding of morbidity after CCM hemorrhage would be helpful to identify patients of higher risk for unfavorable outcome and tailor individualized management. Methods: We identified 282 consecutive patients who referred to our institute from 2014 to 2018 for CCM with symptomatic hemorrhage and had an untreated follow-up period over 6 months after the first hemorrhage. The morbidity after hemorrhage was described in CCM of different features. Nomogram to predict morbidity was formulated based on the multivariable model of risk factors. The predictive accuracy and discriminative ability of nomogram were determined with concordance index (C-index) and calibration curve, and further validated in an independent CCM cohort of a prospective multicenter study from 2019 to 2020. Results: The overall morbidity of CCM was 26.2% after a mean follow-up of 1.9 years (range 0.5–3.5 years) since the first hemorrhage. The morbidity during untreated follow-up was associated with hemorrhage ictus (adjusted odds ratio per ictus increase, 4.17 [95% CI, 1.86–9.33]), modified Rankin Scale score at initial hemorrhage (adjusted odds ratio per point increase, 2.57 [95% CI, 1.82–3.63]), brainstem location (adjusted odds ratio, 2.93 [95% CI, 1.28–6.68]), and associated developmental venous anomaly (adjusted odds ratio, 2.21 [95% CI, 1.01–4.83]). Subgroup analysis revealed similar findings in brainstem and non-brainstem CCM. Nomogram was contracted based on these features. The calibration curve showed good agreement between nomogram prediction and actual observation. The C-index of nomogram predicting morbidity was 0.83 (95% CI, 0.77–0.88). In validation cohort, the nomogram maintained the discriminative ability (C-index, 0.87 [95% CI, 0.78–0.96]). Conclusions: Multiple symptomatic hemorrhages, initial neurological function after hemorrhage, brainstem location, and associated developmental venous anomaly were associated with morbidity of CCM hemorrhage. The nomogram represented a practical approach to provide individualized risk assessment for CCM patients. Registration: URL: https://www.clinicaltrials.gov . Unique identifier: NCT04076449.

SummaryFactors that predispose to thrombus propagation from the femoropopliteal veins to the pelvic veins are poorly understood. Our goal was to determine whether there are characteristics that identify patients with massive deep vein thrombosis (DVT). We compared the 122 (2.5%) patients presenting with massive DVT (pelvic plus lower-extremity DVT) to the 4,674 (97.5%) patients with isolated lower-extremity DVT from a prospective United States multicenter DVT registry. Patients with massive DVT were younger (59.4±18.9 years vs. 64.3±16.8 years; p<0.01), less likely to have hypertension (40% vs. 51%; p=0.02), and more likely to smoke (21% vs. 13%; p=0.02) and have on- going radiation therapy (7% vs. 3%; p=0.02). The massive DVT group more commonly presented with extremity edema (80% vs. 69%; p<0.01) and erythema (21% vs. 12%; p<0.01) than the isolated lower-extremity DVT group. However, after multivariable logistic regression analysis, extremity erythema (adjusted odds ratio 1.86; 95% CI 1.13–3.04) was the only independent sequela of massive DVT and younger age (adjusted odds ratio 1.17 per decreasing decade of age; 95% confidence interval: 1.02-1.34) was the only independent predictor of massive DVT. Thrombus propagation from the femoropopliteal system cannot be reliably predicted using demographic or clinical characteristics.

Background There is a paucity of data relating to the association of gout with the occurrence of hypertension and diabetes mellitus in patients with stroke. This study aimed to determine the association of gout with the risk of hypertension and diabetes mellitus in a cohort of stroke patients from Auckland, Aotearoa New Zealand. Methods A cross-sectional study was conducted among stroke survivors in South and East Auckland, New Zealand from the years 2010 to 2014. Electronic health record data were collected and analysed using Statistical Package for Social Science version 23. Multivariate logistic regression modelling adjusted for age, gender, and ethnicity was conducted to determine the association of gout with the risk of hypertension and diabetes mellitus in patients discharged with a diagnosis of stroke. Results The age-, gender-, and ethnicity-adjusted odds ratio for having hypertension and diabetes mellitus among stroke survivors with gout history were 3.25 (95% confidence interval 1.32–8.03) and 1.94 (95% confidence interval 1.12–3.36), respectively. Māori stroke survivors with gout history had the highest risk of having diabetes mellitus with age- and gender-adjusted odds ratio of 5.10 (95% confidence interval 1.90–18.93). Conclusion The findings from this study suggest gout may be independently associated with an increased risk of hypertension and diabetes mellitus in patients with stroke. Māori who are the indigenous population of New Zealand show a greater risk of diabetes mellitus associated with a gout diagnosis compared to other populations. This finding highlights the importance of the need for further research with Māori stroke survivors and other indigenous populations.

Abstract Background The use of hydroxocobalamin has long been advocated for treating suspected cyanide poisoning after smoke inhalation. Intravenous hydroxocobalamin has however been shown to cause oxalate nephropathy in a single-center study. The impact of hydroxocobalamin on the risk of acute kidney injury (AKI) and survival after smoke inhalation in a multicenter setting remains unexplored. Methods We conducted a multicenter retrospective study in 21 intensive care units (ICUs) in France. We included patients admitted to an ICU for smoke inhalation between January 2011 and December 2017. We excluded patients discharged at home alive within 24 h of admission. We assessed the risk of AKI (primary endpoint), severe AKI, major adverse kidney (MAKE) events, and survival (secondary endpoints) after administration of hydroxocobalamin using logistic regression models. Results Among 854 patients screened, 739 patients were included. Three hundred six and 386 (55.2%) patients received hydroxocobalamin. Mortality in ICU was 32.9% (n = 243). Two hundred eighty-eight (39%) patients developed AKI, including 186 (25.2%) who developed severe AKI during the first week. Patients who received hydroxocobalamin were more severe and had higher mortality (38.1% vs 27.2%, p = 0.0022). The adjusted odds ratio (95% confidence interval) of AKI after intravenous hydroxocobalamin was 1.597 (1.055, 2.419) and 1.772 (1.137, 2.762) for severe AKI; intravenous hydroxocobalamin was not associated with survival or MAKE with an adjusted odds ratio (95% confidence interval) of 1.114 (0.691, 1.797) and 0.784 (0.456, 1.349) respectively. Conclusion Hydroxocobalamin was associated with an increased risk of AKI and severe AKI but was not associated with survival after smoke inhalation.

Abstract Background The world was hit hard by the 2008 recession which led to increased unemployment and financial strain. However, how the recession affected people with pre-existing mental health problems has been understudied. This study investigates the effect of the 2008 recession in Iceland on stress, well-being and employment status of people with regard to whether they are suffering from mental health problems. Methods The study cohort included participants (18–69 years old) of the ‘Health and Wellbeing of Icelanders’, a 3-wave survey conducted before (in 2007) and after (in 2009 and 2012) the recession in 2008. Self-assessed well-being was measured with the Short Warwick-Edinburgh Mental Well-being Scale and the 4-item Perceived Stress Scale. Logistic regression was used to assess the effect of the 2008 recession on self-assessed well-being and employment status in 2009 and 2012, using 2007 as a reference year. Results Participants with no pre-recession mental health problems were at increased risk of both poor well-being, (with adjusted odds ratio at 1.66, in 2009 and 1.64 in 2012) and higher perceived stress, (with adjusted odds ratio at 1.48 in 2009 and 1.53 in 2012), after the recession. Interestingly, no significant change in well-being and perceived stress was observed among participants suffering from pre-recession mental health problems. Both groups had increased risk of unemployment after the recession. Conclusion Results indicate that after recessions, the risk of stress and poor well-being increases only among those who do not suffer from pre-recession mental health problems.
