Burnout syndrome in Spanish medical students

Background: Burnout syndrome is a frequent syndrome related to people that feel a deterioration in their daily activities due to highly demandant psychological requirements in their workplaces. Within last decades, this syndrome has been studied across medical professionals, concluding that stress levels that physicians suffer is high enough to make them develop burnout syndrome. In the case of medical students, there are some recent studies, although with small samples. For this reason, given that this phenomenon may produce a huge impact in medical students' development, the aim of this study is to analyze the influential factors that may contribute to its occurrence. Methods: The necessary information was gathered through a web-based questionnaire, divided in two parts. The first part of the survey included questions related to personal aspects of the students. Burnout related questions (second part) were divided in three subscales to evaluate exhaustion, cynicism, and academic efficacy levels. Results: Family support for studying medicine is associated with lower burnout levels in all three scales of the Maslach Burnout Inventory. The number of years spent in the degree show the opposite trend: the more years in the degree, the higher score in all burnout scales. Conclusions: Burnout syndrome is a problem among medical students in Spain that increases with the number of years studying medicine. It should be also noticed that family support and vocational studies are independent factors related to lower levels of burnout

The NRF2 transcription factor plays a dual role in colorectal cancer : A systematic review

Background: Colorectal cancer is one of the most common cancers worldwide, and is influenced by the interplay of various factors, including a very strong genetic component. For instance, incorrect mitochondrial biogenesis is correlated with increased risk of developing colorectal cancer. Thus, it is important to understand the consequences of changes in both the expression and the correct function of the transcription factors that regulate mitochondrial biogenesis, namely NRF2. Objectives: The main objective of this paper is to characterise the relationship between NRF2 and colorectal cancer by compiling data from an exhaustive literature search. Methods: Information was obtained by defining specific search terms and searching in several databases. After a strict selection procedure, data were tabulated and the relationships between articles were assessed by measuring heterogeneity and by constructing conceptual maps. Results and discussion: We found a general consensus in the literature that the presence of oxidizing agents as well as the inhibition of the NRF2 repressor Keap1 maintain NRF2 expression at basal levels. This predominantly exerts a cytoprotective effect on cells and decreases risk of colorectal cancer. However, if NRF2 is inhibited, protection against external agents disappears and risk of colorectal cancer increases. Interestingly, colorectal cancer risk is also increased when NRF2 becomes overexpressed. In this case, the increased risk arises from NRF2-induced inflammation and resistance to chemotherapy. Conclusion: The proper basal function of NRF2 and Keap1 are essential for preventing oncogenic processes in the colon. Consequently, any disruption to the expression of these genes can promote the genesis and progression of colon cancer

Low birth weight trends in Organisation for Economic Co-operation and Development countries, 2000–2015: economic, health system and demographic conditionings

Background: Low birth weight rates are increasing in both developed and developing countries. Although several maternal factors have been identified as associated with low birth weight, little is known of economic or organization factors influencing this increase. This study aims to ascertain the twenty-first century relationships between the contextual country factors and low birth weight rates. Methods: We analyse trends of low birth weight rates in Organisation for Economic Co-operation and Development (OECD) countries. Data from 2000 to 2015 were obtained from the OECD data base. Their relationships with demographic and economic variables, health habits, woman-related preventive measures, health care system organization and funding, health care work force and obstetric care were analysed using randomeffects linear regression. Results: Low birth weight rates are higher in Southern Europe (7.61%) and lower in Northern Europe (4.68%). Low birth weight rates escalated about 20% in Southern Europe and to less extent in Easter Europe (7%) and Asian/Oceanian countries, while remained stable in America, Central Europe and Northern Europe. Investment in health care, private health system coverage, ratios of paediatricians and obstetricians, average length of admission due to pregnancy or birth and Caesarean section rate were associated with higher low birth weight rates. Factors associated with lower low birth weight rates were health care coverage, public health system coverage, hospitals per million inhabitants, and ratios of health care workers, physicians, midwives and nurses. Conclusions: In OECD countries, LBW rates are related to contextual country characteristics such as GDP per capita, which is inversely related to LBW rate. Health care system factors, including health care coverage or investment in public health system, are directly associated with lower LBW rates

Family history of first degree as a risk factor for colorectal cancer

La autora principal (garante responsable del manuscrito) afirma que este manuscrito es un reporte honesto, preciso y transparente del estudio que se remite a Gaceta Sanitaria, que no se han omitido aspectos importantes del estudio, y que las discrepancias del estudio según lo previsto (y, si son relevantes, registradas) se han explicado.A la Dra. Gemma Castaño Vinyals y al Dr. Manolis Kogevinas por su colaboración en el proyecto.Objetivo: El objetivo de este estudio es evaluar la asociación entre antecedentes familiares (AF) de primer grado y cáncer colorrectal (CCR). Método: Se incluyeron 2857 controles y 1360 casos de CCR, del estudio MCC-Spain. La odds ratio (OR) y el intervalo de confianza del 95% (IC95%) de los AF de primer grado y el CCR se estimaron mediante regresión logística no condicional según la localización tumoral en los casos. Resultados: Los AF de primer grado duplicaron el riesgo de CCR (OR: 2,19;IC95%: 1,80-2,66), incrementándose en aquellos que presentaban dos o más (OR: 4,22; IC95%: 2,29-7,78) y en aquellos cuyos familiares fueron diagnosticados antes de los 50 anos ˜ (OR: 3,24; IC95%: 1,52-6,91). Presentar AF se relacionó con estilos de vida como un menor consumo de vegetales. En cuanto a la asociación de los AF con la localización no se observaron diferencias significativas entre colon y recto, pero sí en la relación de estas con la edad de diagnóstico, presentando más AF los diagnosticados antes de los 50 anos ˜ (OR: 4,79; IC95%: 2,65-8,65). Conclusiones: Presentar AF de primer grado de CCR aumenta las probabilidades de desarrollar este cáncer, y también se elevan cuando el familiar es diagnosticado a edad temprana. Por ello, debe ser una población diana sobre la que incrementar las medidas de prevención.Objective: To evaluate the association between first-degree family history and colorectal cancer (CRC). Method: We analyzed data from 2857 controls and 1360 CRC cases, collected in the MCC-Spain project. The adjusted odds ratio (OR) and 95% confidence interval (95% CI) of association with the family history of CRC was estimated by non-conditional logistic regression. Results: First-degree relatives doubled the risk of CRC (OR: 2.19; 95% CI: 1.80–2.66), increasing in those with two or more (OR: 4.22; 95% CI: 2.29–7.78) and in those whose relatives were diagnosed before 50 years (OR: 3.24; 95% CI: 1.52–6.91). Regarding the association of the family history with the location, no significant differences were observed between colon and rectum, but there were in the relation of these with the age of diagnosis, having more relatives those diagnosed before 50 years (OR: 4.79; 95% CI: 2.65–8.65). Conclusions: First-degree relatives of CRC increase the chances of developing this tumor,they also increase when the relative is diagnosed at an early age. Therefore, it must be a target population on which to carry out prevention measures.El estudio fue parcialmente financiado por la «Acción Transversal del Cáncer», aprobada por el Consejo del Ministerio de España el 11 de octubre de 2007, por el Instituto de Salud Carlos III-FEDER (PI08 / 1770, PI08 / 0533, PI08 / 1359, PS09 / 00773-Cantabria, PS09 / 01286-León, PS09 / 01903-Valencia, PS09 / 02078-Huelva, PS09 / 01662-Granada, PI11 / 01403, PI11 / 01889-FEDER, PI11 / 00226, PI11 / 01810, PI11 / 02213, PI12 / 00488, PI12 / 00265, PI12 / 01270, PI12 / 00715, PI12 / 00150, PI14 / 01219, PI14 / 0613, PI15 / 00069, PI15 / 00914, PI15 / 01032, PI17CIII / 00034), así como a través de CIBERESP CB06/02/0073, cofinanciado por el Fondo Europeo de Desarrollo Regional (FEDER).

Misperception of the cardiovascular risk in patients with rheumatoid arthritis

ABSTRACT: The risk of cardiovascular (CV) disease and mortality is increased by rheumatoid arthritis (RA). However, data on how RA patients perceive their own CV risk and their adherence to CV prevention factors are scarce. We conducted an observational study on 266 patients with RA to determine whether the perceived CV risk correlates to the objective CV risk, and if it influences their compliance with a Mediterranean diet and physical exercise. The objective CV risk was calculated according to the modified European League Against Rheumatism (EULAR) Systematic Coronary Risk Evaluation (SCORE). The perceived CV risk did not correlate to the objective CV risk. The correlation was even lower when carotid ultrasound was used. Notably, 64.62% of patients miscalculated their CV risk, with 43.08% underestimating it. Classic CV risk factors, carotid ultrasound markers and ESR and CRP showed significant correlation with the objective CV risk. However, only hypertension and RA disease features showed association with the perceived CV risk. Neither the objective CV risk nor the perceived CV risk were associated with the accomplishment of a Mediterranean diet or physical activity. In conclusion, RA patients tend to underestimate their actual CV risk, giving more importance to RA features than to classic CV risk factors. They are not concerned enough about the beneficial effects of physical activity or diet.This work was partially supported by RETICS Programs, RD08/0075 (RIER), RD12/0009/0013 and RD16/0012 from “Instituto de Salud Carlos III” (ISCIII) (Spain).

Feeding in the first six months of life is associated with the probability of having bronchiolitis: a cohort study in Spain

Background: Breastfeeding is associated with lower incidence and severity of lower respiratory tract disease. However, little is known about the relationship between feeding type and breastfeeding duration with bronchiolitis in a child's first year. Methods: A prospective cohort study of 969 newborn babies were followed-up for 12 months to determine breastfeeding duration, feeding type, feeding trajectory, and bronchiolitis episodes at Marqués de Valdecilla University Hospital, Spain in 2018. Type of feeding was recorded by interviewing mothers at the time of hospital discharge and at 2, 4, 6, 9 and 12 months of life, in three categories: breastfeeding, mixed feeding and infant formula. Type of feeding at hospital discharge refers to feeding from birth to discharge. In any other times studied, it refers to feeding in the last 24 h. The association between the feeding type and bronchiolitis was analysed using logistic regression. Poisson regression was used to evaluate the association between feeding type and the number of bronchiolitis episodes with Kaplan-Meier estimators presenting the cumulative probability of suffering bronchiolitis. The results were adjusted for mother and child characteristics. Results: Our data shows exclusive breastfeeding and mixed breastfeeding reduce the number of episodes of bronchiolitis. Regarding feeding at 4 months, exclusive breastfeeding reduced by 41% the number of episodes of bronchiolitis (adjusted incidence Ratio (aIR) 0.59, 95% CI 0.46, 0.76) and mixed feeding by 37% (aIR 0.63, 95% CI 0.47, 0.86). Moreover, changing from exclusive breastfeeding to mixed feeding increased the incidence of bronchiolitis compared with continuing exclusive breastfeeding. An early swap to mixed breastfeeding before months 2 or 4, was associated with a reduced the number of episodes of bronchiolitis, (aIR 0.53, 95% CI 0.39, 0.73 if introduction of mixed breastfeeding before month 2, and aIR 0.61, 95% CI 0.45, 0.83 if introduction of mixed breastfeeding before month 4), when compared with infant formula alone. Conclusions: Any breastfeeding was associated with lower incidence of bronchiolitis and number of episodes of bronchiolitis in the first year of life. Consequently, promoting programmes facilitating exclusive or mixed breastfeeding would be a relevant measure in the prevention of bronchiolitis

Pregnancy and birth outcomes during the early months of the COVID-19 pandemic: The MOACC-19 cohort

The new coronavirus, SARS-CoV-2, is devastating for specific groups of patients, but currently there is not enough information concerning its effects on pregnant women. The purpose of this study is to identify the impact of SARS-CoV-2 infection on pregnancy and the consequences that it could cause. We studied a cohort of pregnant ladies who were tested for SARS-CoV-2 infection by RT-PCR and classified as infected or not infected. The recruitment was carried out in the HUMV hospital, a third-level hospital located in Santander, northern Spain. It started on 23 March 2020 and ended on 14 October 2020. Data from our cohort were compared to another cohort recruited in 2018 at the same hospital. We found that gestational hypertension, placental abruptio, and home exposure to an infected person, among other variables, could be associated with SARS-CoV-2 infection. In conclusion, we consider pregnant women a high-risk group of patients towards a possible SARS-CoV-2 infection, especially those who present with conditions such as gestational hypertension or obesity; moreover, we think that SARS-CoV-2 infection could increase the possibilities of having an abruptio placentae, although this result was found in only a few women, so it requires further confirmation.Funding: This research was funded by the Spanish Instituto de Salud Carlos III (ISCIII), grant number COV20/00923, and a grant from the Ministerio de Educación (Beca de colaboración) (MRD)

Alterations in PGC1α expression levels are involved in colorectal cancer risk: a qualitative systematic review

[EN] Colorectal cancer (CRC) is a major global public health problem and the second leading cause of cancer-related death. Mitochondrial dysfunction has long been suspected to be involved in this type of tumorigenesis, as supported by an accumulating body of research evidence. However, little is known about how mitochondrial alterations contribute to tumorigenesis. Mitochondrial biogenesis is a fundamental cellular process required to maintain functional mitochondria and as an adaptive mechanism in response to changing energy requirements. Mitochondrial biogenesis is regulated by peroxisome proliferator-activated receptor gamma coactivator 1-α (PPARGC1A or PGC1α). In this paper, we report a systematic review to summarize current evidence on the role of PGC1α in the initiation and progression of CRC. The aim is to provide a basis for more comprehensive research.S

Perception of Medical Students on the Need for End-of-Life Care: A Q-Methodology Study

End-of-life care and the limitation of therapeutic effort are among the most controversial aspects of medical practice. Many subjective factors can influence decision-making regarding these issues. The Q methodology provides a scientific basis for the systematic study of subjectivity by identifying different thought patterns. This methodology was performed to find student profiles in 143 students at Cantabria University (Spain), who will soon deal with difficult situations related to this topic. A chi-square test was used to compare proportions. We obtained three profiles: the first seeks to ensure quality of life and attaches great importance to the patient's wishes; the second prioritizes life extension above anything else; the third incorporates the economic perspective into medical decision-making. Those who had religious beliefs were mostly included in profile 2 (48.8% vs. 7.3% in profile 1 and 43.9% in profile 3), and those who considered that their beliefs did not influence their ethical principles, were mainly included in profile 3 (48.5% vs. 24.7% in profile 1 and 26.8% in profile 2). The different profiles on end-of-life care amongst medical students are influenced by personal factors. Increasing the clinical experience of students with terminally ill patients would contribute to the development of knowledge-based opinion profiles and would avoid reliance on personal experiences.Funding: This research received a grant from the Spanish Minister of Education (Beca de colaboración

Results of Pregnancy Control before and during the COVID-19 Pandemic: A Comparison of Two Cohorts

The COVID-19 pandemic placed pregnant women at high risk, but behavioural changes have also led to lower rates of preterm births in high-income countries. The main goal of this article is to study the ongoing impact of the COVID-19 pandemic on pregnancy control and outcomes; this is a joint analysis of two cohorts. The pre-pandemic cohort includes 969 pregnant women recruited in 2018. The pandemic cohort comprises 1168 pregnant women recruited in 2020. Information on demographic and socioeconomic characteristics, reproductive history, characteristics of the current pregnancy and its outcome were obtained from medical records. Birth by Caesarean section was more frequent in the pre-pandemic cohort (adjusted odds ratio (OR) = 0.71, 95% confidence interval (CI): 0.55-0.92). A birth weight lower than 2500 g and higher than 4000 g occurred more frequently in the pre-pandemic cohort (adjusted OR = 0.62, 95% CI: 0.41-0.93 for lower than 2500 g and adjusted OR = 0.30, 95% CI: 0.20-0.46 for higher than 4000 g). Exclusive breastfeeding upon hospital discharge was more frequent in the pandemic cohort than in the pre-pandemic cohort (60% vs. 54%, p = 0.005), with adjusted OR = 0.67, 95% CI: 0.52-0.86 for mixed breastfeeding and infant formula. In conclusion, we report reductions in Caesarean sections and reduced numbers of low birth weight babies during the pandemic in a hospital located in northern Spain. Further analysis will clarify if these reductions are related to changes in health-related behaviour or healthcare operation
