The Side Effect of Political Standing: Corporate Activism and Its Impact on Stock Returns

[EN]: Taking sides on controversial political issues such as gun control, abortion, immigration, or diversity is increasingly common among large companies. What remains unclear, however, is whether this type of strategy—known as “corporate activism”—has positive or negative effects on these companies. The use of the concept of corporate activism on different variables affecting the companies is relatively recent. This article analyses the effect of corporate activism on the stock market performance of US companies through the analysis of the sample collected. Although there are some recent articles published on this topic, none of them measures the risk associated with the use of this type of strategy. For the development of the research, the well‐known Fama–French modelling framework is applied to estimate the differences between companies that participate in corporate activism initiatives versus those that remain outside this strategy. The findings complement previous research showing that companies that use corporate activism have lower market risk than companies that do not engage in this type of strategy. These results can be useful in identifying the advantages and disadvantages of corporate activism initiatives and, in addition, they can also help companies to evaluate the use of corporate activism as a strategic tool and as a driver of social change.SIThis work has been partially supported by the Government of Madrid (Comunidad de Madrid, Spain) under the multiannual agreement with Universidad Complutense de Madrid, in the line Excellence Programme for University Teaching Staff, in the context of the V PRICIT (Regional Programme for Research and Technological Innovation)

Conocimiento del Anticonceptivo de Emergencia o “Píldora del Día Siguiente”, en Estudiantes Universirarios

Introducción.

Objetivo. Determinar el nivel de conocimiento que tienen los jóvenes universitarios sobre el uso de la píldora del día siguiente, mediante la aplicación de un cuestionario, con la finalidad de tener un referente actual del fenómeno. Metodología. Estudio transversal, descriptivo, se trabajó con 308 estudiantes de la Facultad de Derecho y Química, de una universidad pública. Muestreo fue por conveniencia. Se consideraron alumnos cuyas parejas sexuales fueran del sexo contrario o bien, ambos y que tuvieran vida sexual activa, de quienes se obtuvo consentimiento verbal. Análisis de datos mediante estadística descriptiva usando el programa EXCEL y SPSS. Resultados. Se tuvieron 210 cuestionarios de la Facultad de Derecho y 98 de Química. 58% de los jóvenes fueron mujeres. Del total de participantes, 264 respondieron a la pregunta de si han usado alguna vez la pastilla. De estos, 77.3% sí han recurrido a ella desde que iniciaron su vida sexual. Con respecto al nivel de conocimientos, los alumnos de Derecho, tuvieron 30% de conocimiento regular y malo y en Química 30.6%. Con respecto al género, 31% de los datos erróneos, fueron de las mujeres y 40% de los varones. Conclusiones. Un alto porcentaje de alumnos han usado este medicamento, por lo que es necesario reforzar los conocimientos sobre su correcto uso.   Introduction. Unwanted pregnancies have become a serious public health problem, which is closely related to poor sexual education, adoption of risky sexual behaviors and little knowledge of emergency contraceptive methods. Objective. To determine the level of knowledge that young university students have about the use of the morning-after pill, through the application of a questionnaire, in order to have a current frame of reference about this phenomenon. Methodology. Cross-sectional, descriptive study. We worked with 308 students from the College of Law and Chemistry of a public university. We used convenience sampling. We considered students whose sexual partners were of the opposite or same sex, and who were sexually active, and their verbal consent was obtained. Data analysis was conducted through descriptive statistics using EXCEL and the SPSS program. Results. 210 questionnaires were obtained from the College of Law and 98 from Chemistry. 58% of the participants were women. Of the total participants, 264 responded to the question of whether they had ever used the pill. Of these, 77.3% indicated they have resorted to it since they became sexually active. Regarding the level of knowledge, 30% of Law students had average and poor knowledge, and Chemistry students 30.6%. Regarding gender, 31% of those with no knowledge of the pill were women and 40% were men. Conclusion. A high percentage of students have used this medication, so it is necessary to reinforce knowledge about its correct use

First-trimester screening for pre-eclampsia and small for gestational age: A comparison of the gaussian and Fetal Medicine Foundation algorithms

Preeclampsia d'inici precoç; Primer trimestreEarly-onset pre-eclampsia; First trimesterPreeclampsia de inicio precoz; Primer trimestreObjective Pre-eclampsia (PE) and small for gestational age (SGA) can be predicted from the first trimester. The most widely used algorithm worldwide is the Fetal Medicine Foundation (FMF) algorithm. The recently described Gaussian algorithm has reported excellent results although it is unlikely to be externally validated. Therefore, as an alternative approach, we compared the predictive accuracy for PE and SGA of the Gaussian and FMF algorithms. Methods Secondary analysis of a prospective cohort study was conducted at Vall d'Hebron University Hospital (Barcelona) with 2641 singleton pregnancies. The areas under the curve for the predictive performance for early-onset and preterm PE and early-onset and preterm SGA were calculated with the Gaussian and FMF algorithms and subsequently compared. Results The FMF and Gaussian algorithms showed a similar predictive performance for most outcomes and marker combinations. Nevertheless, significant differences for early-onset PE prediction favored the Gaussian algorithm in the following combinations: mean arterial blood pressure (MAP) with pregnancy-associated plasma protein A, MAP with placental growth factor, and MAP alone. Conclusions The first-trimester Gaussian and FMF algorithms have similar performances for PE and SGA prediction when applied with all markers within a routine care setting in a Spanish population, adding evidence to the external validity of the FMF algorithm

Reference values for interleukin-6 in the amniotic fluid of asymptomatic pregnant women

Amniocentesis; Interleukin-6; Intra-amniotic inflammationAmniocentesi; Interleucina-6; Inflamació intraamniòticaAmniocentesis; Interleucina-6; Inflamación intraamnióticaIntroduction Nowadays, proinflammatory factors are considered to play an important role in the pathophysiology of threatened preterm labor or chorioamnionitis. The aim of this study was to establish the normal reference range for interleukin-6 (IL-6) levels in the amniotic fluid and to identify factors which may alter this value. Material and methods Prospective study in a tertiary-level center including asymptomatic pregnant women undergoing amniocentesis for genetic studies from October 2016 to September 2019. IL-6 measurements in amniotic fluid were performed using a fluorescence immunoassay with microfluidic technology (ELLA Proteinsimple, Bio Techne). Maternal history and pregnancy data were also recorded. Results This study included 140 pregnant women. Of those, women who underwent termination of pregnancy were excluded. Therefore, a total of 98 pregnancies were included in the final statistical analysis. The mean gestational age was 21.86 weeks (range: 15–38.7) at the time of amniocentesis, and 38.6 weeks (range: 30.9–41.4) at delivery. No cases of chorioamnionitis were reported. The log10 IL-6 values follow a normal distribution (W = 0.990, p = 0.692). The median, and the 5th, 10th, 90th, and 95th percentiles for IL-6 levels were 573, 105, 130, 1645, and 2260 pg/mL, respectively. The log10 IL-6 values were not affected by gestational age (p = 0.395), maternal age (p = 0.376), body mass index (p = 0.551), ethnicity (p = 0.467), smoking status (p = 0.933), parity (p = 0.557), method of conception (p = 0.322), or diabetes mellitus (p = 0.381). Conclusions The log10 IL-6 values follow a normal distribution. IL-6 values are independent of gestational age, maternal age, body mass index, ethnicity, smoking status, parity and method of conception. Our study provides a normal reference range for IL-6 levels in the amniotic fluid that can be used in future studies. We also observed that normal IL-6 values were higher in the amniotic fluid than in serum.Some of the authors are members of the European Reference Network on Rare Congenital Malformations and Rare Intellectual Disability ERN-ITHACA (EU Framework Partnership Agreement ID: 3HP-HP-FPA ERN-01-2016/739516)

JKST6, a novel multikinase modulator of the BCR-ABL1/STAT5 signaling pathway that potentiates direct BCR-ABL1 inhibition and overcomes imatinib resistance in chronic myelogenous leukemia

Chronic myelogenous leukemia (CML) is a hematological malignancy that highly depends on the BCR-ABL1/STAT5 signaling pathway for cell survival. First-line treatments for CML consist of tyrosine kinase inhibitors that efficiently target BCR-ABL1 activity. However, drug resistance and intolerance are still therapeutic limitations in Ph+ cells. Therefore, the development of new anti-CML drugs that exhibit alternative mechanisms to overcome these limitations is a desirable goal. In this work, the antitumoral activity of JKST6, a naphthoquinone-pyrone hybrid, was assessed in imatinib-sensitive and imatinib-resistant human CML cells. Live-cell imaging analysis revealed JKST6 potent antiproliferative activity in 2D and 3D CML cultures. JKST6 provoked cell increase in the subG1 phase along with a reduction in the G0/G1 phase and altered the expression of key proteins involved in the control of mitosis and DNA damage. Rapid increases in Annexin V staining and activation/cleavage of caspases 8, 9 and 3 were observed after JKST6 treatment in CML cells. Of interest, JKST6 inhibited BCR-ABL1/STAT5 signaling through oncokinase downregulation that was preceded by rapid polyubiquitination. In addition, JKST6 caused a transient increase in JNK and AKT phosphorylation, whereas the phosphorylation of P38-MAPK and Src was reduced. Combinatory treatment unveiled synergistic effects between imatinib and JKST6. Notably, JKST6 maintained its antitumor efficacy in BCR-ABL1-T315I-positive cells and CML cells that overexpress BCR-ABL and even restored imatinib efficacy after a short exposure time. These findings, together with the observed low toxicity of JKST6, reveal a novel multikinase modulator that might overcome the limitations of BCR-ABL1 inhibitors in CML therapy.This research has been funded by Spanish Ministry of Economy and Competitiveness - MINECO - (SAF 2015–65113-C2–1-R and RTI2018–094356-B-C21 to AEB, SAF2015–65113-C2–2 to LFP, SAF2017–88026-R to JL) with the co-funding of European Regional Development Fund (EU-ERDF), Canary Islands Government (CEI2018–23/ACIISI to BG, CEI2019–08/ACIISI to BG and LFP, ProID2021010037 to AEB, LFP and BG) and "Juan de la Cierva Incorporacion" Grant Program from the Ministry of Science, Innovation and Universities (IJC2018-035193-I to CR).

Impact of SARS-CoV-2 RNAemia and other risk factors on long-COVID: A prospective observational multicentre cohort study

As the COVID-19 pandemic has progressed, long-COVID has emerged as a major problem that poses a significant challenge for attending physicians and health care policy makers. Therefore, we read with much interest the recently published unicentre study in the Journal of Infection by Righi et al.,1 carried out on 465 adult COVID-19 patients (235 [50.5%] hospital-admitted) followed-up during nine months, concluding that those with advanced age, intensive care unit (ICU) admission, and multiple symptoms at onset were more likely to have long-term COVID-19 symptoms, with negative impact on physical and mental wellbeing. Other studies have found that female gender, age, longer hospital stay, pre-existing hypertension, cardiovascular disease, diabetes, chronic obstructive pulmonary disease, smoking, obesity, and chronic alcoholism increase the likelihood of long-COVID.2,3 It is known that SARS-CoV-2 RNAemia is a predictor of COVID-19 severity and in-hospital complications.4,5 However, to the best of our knowledge, only two studies have assessed, up to one or three months after the acute COVID-19 onset, whether SARS-CoV-2 RNAemia may have an impact on long-COVID,6,7 both finding that RNAemia at presentation might predict the persistence of symptoms. However, these studies did not provide information regarding long-COVID symptoms nor the association with SARS-CoV-2 RNAemia beyond three months, and could not differentiate between “true” long-COVID and the convalescence phase of the SARS-CoV-2 infection.A.R. has received a predoctoral research grant from the Instituto de Salud Carlos III, Spanish Ministry of Science, Innovation and Universities, (PFIS grant FI18/00183).

Beneficial Effect of Ursodeoxycholic Acid in Patients with ACOX2 Deficiency-Associated Hypertransaminasemia

Background: A variant (p.Arg225Trp) of peroxisomal acyl-CoA oxidase 2 (ACOX2), involved in bile acid (BA) side-chain shortening, has been associated with unexplained persistent hypertransaminasemia and accumulation of C27-BAs, mainly trihydroxycholestanoic acid (THCA). Aims: To investigate the prevalence of ACOX2 deficiency-associated hypertransaminasemia (ADAH), its response to ursodeoxycholic acid (UDCA), elucidate its pathophysiological mechanism and identify other inborn errors that could cause this alteration. Methods & results: Among 33 patients with unexplained hypertransaminasemia from 11 hospitals, and 13 of their relatives, 7 individuals with abnormally high C27-BA levels (>50% of total BAs) were identified by HPLC-MS/MS. The p.Arg225Trp variant was found in homozygosity (exon amplification/sequencing) in 2 patients and 3 family members. Two additional non-related patients were heterozygous carriers of different alleles: c.673C>T (p.Arg225Trp) and c.456_459del (p.Thr154fs). In ADAH patients, impaired liver expression of ACOX2, but not ACOX3, was found (immunohistochemistry). Treatment with UDCA normalized transaminases levels. Incubation of HuH-7 liver cells with THCA, which was efficiently taken up, but not through BA transporters, increased ROS production (flow cytometry), ER stress biomarkers (GRP78, CHOP and XBP1-S/XBP1-U ratio), and BAX¿ expression (RT-qPCR and immunoblot), whereas cell viability was decreased (MTT). THCA-induced cell toxicity was higher than that of major C24-BAs and was not prevented by UDCA. Fourteen predicted ACOX2 variants were generated (site-directed mutagenesis) and expressed in HuH-7 cells. Functional tests to determine their ability to metabolize THCA identified six with the potential to cause ADAH. Conclusion: Dysfunctional ACOX2 has been found in several patients with unexplained hypertransaminasemia. This condition can be accurately identified by a non-invasive diagnostic strategy based on plasma BA profiling and ACOX2 sequencing. Moreover, UDCA treatment can efficiently attenuate liver damage in these patients.This study was supported by the following grants: CIBERehd (EHD15PI05/2016); Fondo de Investigaciones Sanitarias, Instituto de Salud Carlos III, Spain (PI19/00819 and PI20/00189), co-funded by European Regional Development Fund/European Social Fund, “Investing in your future”; “Junta de Castilla y León” (SA074P20); Fundació Marato TV3 (201916–31); AECC Scientific Foundation (2017/2020), Spain; and “Centro Internacional sobre el Envejecimiento” (OLD-HEPAMARKER, 0348_CIE_6_E), Spain.

Safety and effectiveness of isavuconazole in real-life non-neutropenic patients

Objectives: Information is scarce on clinical experiences with non-neutropenic patients with invasive fungal infection (IFI) receiving isavuconazole. We aimed to report the safety and effectiveness of this drug as a first-line treatment or rescue in real life. Methods: A retrospective, observational multicentric study of non-neutropenic patients who received isavuconazole as an IFI treatment at 12 different university hospitals (January 2018-2022). All patients met criteria for proven, probable or possible IFI according to EORTC-MSG. Results: A total of 238 IFIs were treated with isavuconazole during the study period. Combination therapy was administered in 27.7% of cases. The primary IFI was aspergillosis (217, 91.2%). Other IFIs treated with isavuconazole were candidemia (n = 10), mucormycosis (n = 8), histoplasmosis (n = 2), cryptococcosis (n = 2), and others (n = 4). Median time of isavuconazole treatment was 29 days. Only 5.9% (n = 14) of cases developed toxicity, mainly hepatic-related (10 patients, 4.2%). Nine patients (3.8%) had treatment withdrawn. Successful clinical response at 12 weeks was documented in 50.5% of patients. Conclusion: Isavuconazole is an adequate treatment for non-neutropenic patients with IFIs. Toxicity rates were low and its effectiveness was comparable to other antifungal therapies previously reported. (c) 2024 The Authors.
