Climate change and stock returns in the european market: An environmental intensity approach.

Climate change has become a risk that companies, governments and stakeholders must consider. Climate risk affects everything from people's health to the performance of companies. The European Union has approved various legislations and action plans to counteract the effects of climate change in a pioneering strategy. Companies can play a critical role in mitigating climate change and creating a more sustainable future by integrating environmental considerations into their decision-making processes. However, this integration may impact their performance. This paper aims to analyse the effect of climate change on the stock returns of European companies. The study sample consists of 265 companies listed in the Stoxx 600 index between 2015 and 2021 and the methodology used is the econometric method for panel data. The results show that carbon emissions have a negative effect on the performance of companies. Oppositely, a good rating in the environmental pillar has a positive impact on returns.

Computable general equilibrium models for sustainable development: past and future.

Computable general equilibrium models (CGE) are used to estimate the ex-ante quantitative impact of a change in economic policy. There is a bulk of research in the field of sustainable development applying it for testing implementation of carbon taxation, analyzing reductions of greenhouse gas (GHG), or addressing agricultural issues to work the land efficiently. The main objective of this review is to provide an exhaustive analysis of the literature about these models and their evolution over the last 50 years. The search was conducted in the main academic databases (Scopus and Web of Science), where 1353 articles were found from 1966 to 2019 related to the topic. The results of the descriptives, relational, and content analyses carried out show the current state of the-art, trends, subfields of research, and future gaps to fulfill. This article contributes to the literature that uses CGE models providing an overview of its different applications in the field of sustainability. It gives useful insights to academics who want to further research the field.

Patient safety and adverse events related with obstetric care.

PURPOSE: To determine the frequency and distribution of Adverse Events (AE) in obstetrics departments at Spanish hospitals. METHODS: We present a retrospective cohort study including 816 women admitted to the obstetrics departments at 41 hospitals that took part in the National Adverse Effects Study in Spain (ENEAS) and an extension of this study in all hospitals located in two Autonomous Regions. To identify AE, nurses from each participating hospital examined all medical records, and completed a validated screening guide. A team of external reviewers evaluated the medical records of all women who met at least one of the criteria in the screening guide to verify all AE. The main outcome measure was the incidence of AE during hospitalization. RESULTS: The cumulative incidence of patients with obstetric care-related AE was 3.6% (95% CI 2.3-4.8). The most frequent AE were those related with surgical interventions or procedures (59.4%). None of the AE detected were considered severe. 36.7% of the AE lengthened the woman's hospital stay, and 13.3% led to hospital admission. Additional procedures were needed after 71.9% of the AE, and additional treatment was needed after 59.4%. 56.3% of the AE were considered preventable. CONCLUSIONS: Obstetric care is characterized by generally younger ages among patients, their low frequency of comorbidities and high expectations for successful outcomes of care. However, some factors can increase obstetric risk and favor the appearance of preventable incidents and AE. Systems are needed to detect preventable AE, and measures are needed to reduce risks or attenuate their consequences.

Pelvic abscess after oocyte retrieval in women with endometriosis: A case series.

BACKGROUND: Pelvic inflammatory disease with progression to pelvic abscess is a rare complication after oocyte retrieval during in vitro fertilization cycles. However, in patients with endometriosis the risk appears to be increased. Many authors agree on the need for antibiotic prophylaxis during the oocyte retrieval in these patients, but there is no consensus regarding the best antibiotic. CASE: We discuss 3 clinical cases of tubo-ovarian abscess in women with endometriosis after oocyte retrieval despite antibiotic prophylaxis between 2004 and 2011 at our center, and discuss our experience in the context of earlier reports. CONCLUSION: It is unclear whether antibiotic prophylaxis is necessary in these women, and which antibiotic is best. Only douching with povidone-iodine appears to decrease the rate of pelvic infection.

Bakri balloon for the management of postpartum hemorrhage.

The aim of this study was to evaluate the effectiveness of the Bakri balloon in treating postpartum hemorrhage refractory to medical treatment. This retrospective study included 24 women with postpartum hemorrhage treated with a Bakri balloon as a conservative therapeutic option. The Bakri balloon was successful in controlling hemorrhage in 87.5% of the women. It was effective in all women with vaginal delivery (five of five) and in all women with uterine atony who did not respond to medical uterotonic treatment (eight of eight). Its ease of use and high effectiveness make the Bakri balloon a useful approach for the conservative management of acute postpartum hemorrhage. This device reduces bleeding, shortens the hospital stay and avoids the need for more aggressive procedures.

Fetal sex and perinatal outcomes.

OBJECTIVE: To evaluate the relationship of fetal sex with obstetric risk factors and perinatal outcomes. MATERIAL AND METHODS: Retrospective study of deliveries during 2003-2009 at a tertiary hospital based on the analysis of obstetric and neonatal risk variables according to neonatal sex. RESULTS: Of the 29,530 deliveries studied, the neonate was a boy in 15,038 (50.92%) and a girl in 14,492 (49.08%). The rates of gestational diabetes, prematurity, true umbilical cord knot and nuchal cord were higher for male newborns, whereas the rate of echographic diagnosis of intrauterine fetal growth retardation was higher for female newborns. Mothers of male fetuses had higher rates of cesarean delivery and instrumental vaginal delivery. The indication for ending labor due to the non-reassuring fetal heart rate was also more frequent among male newborns. This group had higher rates of acidemia, although there were no significant differences between sexes in other short-term neonatal outcomes. In all subgroups analyzed here, fetal weight was higher in male newborns. CONCLUSIONS: Male sex is an independent risk factor for unfavorable outcomes of pregnancy and delivery.
