Prevalence, Risk Factors and Burnout Levels in Intensive Care Unit Nurses: A Systematic Review and Meta-Analysis
Nursing is considered to be an at-risk profession of burnout due to daily exposure to
difficult situations such as death and pain care. In addition, some units such as the intensive care
unit (ICU), can be stressful due to high levels of morbidity and mortality and ethical dilemmas.
Burnout causes a deterioration in quality of care, increasing the risk of mortality in patients due to
poor performance and errors in the healthcare environment. The aim of this study was to analyse
the levels, prevalence and related factors of burnout in ICU nurses. A systematic review and metaanalysis
were carried out in the Medline, Scopus and CINAHL databases. Fifteen articles were found
for the systematic review and four for the meta-analysis. With a sample of n = 1986 nurses, the
meta-analytic estimate prevalence for high emotional exhaustion was 31% (95% CI, 8–59%), for high
depersonalization was 18% (95% CI, 8–30%), and for low personal accomplishment was 46% (95% CI,
20–74%). Within the dimensions of burnout, emotional exhaustion had a significant relationship with
depression and personality factors. Both sociodemographic factors (being younger, single marital
status, and having less professional experience in ICU) and working conditions (workload and
working longer hours) influence the risk of burnout syndrome
Anxiety, Distress and Stress among Patients with Diabetes during COVID-19 Pandemic: A Systematic Review and Meta-Analysis
The prevalence of mental health disorders has increased during the COVID-19 pandemic.
Patients with chronic diseases, such as diabetes, are a particularly vulnerable risk group. This study
aims to assess the levels and prevalence of anxiety, distress, and stress in patients with diabetes during
the COVID-19 pandemic. A systematic review was conducted in CINAHL, Cochrane, LILACS,
Medline, SciELO, and Scopus in accordance with the Preferred Reporting Items for Systematic
Reviews and Meta-Analyses (PRISMA) statement. Thirty-seven articles with a total of 13,932 diabetic
patients were included. Five meta-analyses were performed. The prevalence of anxiety was
23% (95% CI = 19–28) in T1DM and 20% (95% CI = 6–40) in T2DM patients. For diabetes distress
it was 41% (95% CI = 24–60) for T1DM and 36% in T2DM patients (95% CI = 2–84). For stress,
the prevalence was 79% (95% CI = 49–98) in T1DM patients. People with diabetes have significant
psychiatric comorbidity as well as psychological factors that negatively affect disease management,
increasing their vulnerability in an emergency situation. To establish comprehensive care in diabetic
patients addressing mental health is essential, as well as including specific policy interventions to
reduce the potential psychological harm of the COVID-19 pandemic
Continuity of Nursing Care in Patients with Coronary Artery Disease: A Systematic Review
Coronary artery disease is the leading cause of death worldwide and patient continuity
of care is essential. Health professionals can help in the transition stage by providing resources to
achieve pharmacological treatment adherence, as well as social and emotional support. The objective
was to analyse the effects of nursing interventions based on continuity of care in patients with
coronary artery disease after hospital discharge. A systematic review of randomised controlled trials
and quasi-experimental studies was carried out. Cochrane, CINAHL, Health & medical collection,
Medline, and Scopus databases were consulted in January 2022. PRISMA guidelines were followed
with no time limits. In total, 16 articles were included with a total of 2950 patients. Nurse-led
continuity of care programs improved the monitoring and control of the disease. Positive effects
were found in the quality of life of patients, and in mental health, self-efficacy, and self-care capacity
dimensions. Clinical parameters such as blood pressure and lipid levels decreased. The continuity
of care provided by nurses had a positive influence on the quality of life of patients with coronary
artery disease. Nurse-led care focused on the needs and resources, including continuity of care, plays
a key role
Explanatory Models of Burnout Diagnosis Based on Personality Factors and Depression in Managing Nurses
This study forms part of the Doctoral Thesis of the first-named author (Maria Jose Membrive-Jimenez).
Funding for this study was provided by the Andalusian Government Excellence Project (P11-HUM-7771).Nurse managers are affected by burnout due to the high degree of interaction between
managers with their registered nurses. Explanatory models based on psychological, and personality
related variables purvey an estimation to level changes in the three dimensions of the burnout
syndrome. A categorical-response logistic ordinal regression model, supported on a quantitative,
crosscutting, multicentre, descriptive study with 86 nursing managers in the Andalusian Health
Service in Granada, Spain is performed for each dimension. The three models included different
variables related to personality, as well as depression as the only explanatory variable included in all
the models. The risk factor neuroticism was significant at population level and related to emotional
exhaustion, whilst responsibility was significant in the model estimated to personal accomplishment
dimension. Finally, depression was significant for the three dimensions of Burnout. This analysis
provides useful information to help the diagnosis and evolution of this syndrome in this collective.Andalusian Government Excellence Project P11-HUM-777
The CARMENES search for exoplanets around M dwarfs High-resolution optical and near-infrared spectroscopy of 324 survey stars
The CARMENES radial velocity (RV) survey is observing 324 M dwarfs to search for any orbiting planets. In this paper, we present the survey sample by publishing one CARMENES spectrum for each M dwarf. These spectra cover the wavelength range 520–1710 nm at a resolution of at least R >80 000, and we measure its RV, Hα emission, and projected rotation velocity. We present an atlas of high-resolution M-dwarf spectra and compare the spectra to atmospheric models. To quantify the RV precision that can be achieved in low-mass stars over the CARMENES wavelength range, we analyze our empirical information on the RV precision from more than 6500 observations. We compare our high-resolution M-dwarf spectra to atmospheric models where we determine the spectroscopic RV information content, Q, and signal-to-noise ratio. We find that for all M-type dwarfs, the highest RV precision can be reached in the wavelength range 700–900 nm. Observations at longer wavelengths are equally precise only at the very latest spectral types (M8 and M9). We demonstrate that in this spectroscopic range, the large amount of absorption features compensates for the intrinsic faintness of an M7 star. To reach an RV precision of 1 m s−1 in very low mass M dwarfs at longer wavelengths likely requires the use of a 10 m class telescope. For spectral types M6 and earlier, the combination of a red visual and a near-infrared spectrograph is ideal to search for low-mass planets and to distinguish between planets and stellar variability. At a 4 m class telescope, an instrument like CARMENES has the potential to push the RV precision well below the typical jitter level of 3–4 m s−1
The CARMENES search for exoplanets around M dwarfs HD147379 b: A nearby Neptune in the temperate zone of an early-M dwarf
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379 (V = 8.9 mag, M = 0.58 ± 0.08 M⊙), a bright M0.0 V star at a distance of 10.7 pc, is found to undergo periodic RV variations with a semi-amplitude of K = 5.1 ± 0.4 m s−1 and a period of P = 86.54 ± 0.06 d. The RV signal is found in our CARMENES data, which were taken between 2016 and 2017, and is supported by HIRES/Keck observations that were obtained since 2000. The RV variations are interpreted as resulting from a planet of minimum mass mP sin i = 25 ± 2 M⊕, 1.5 times the mass of Neptune, with an orbital semi-major axis a = 0.32 au and low eccentricity (e < 0.13). HD 147379 b is orbiting inside the temperate zone around the star, where water could exist in liquid form. The RV time-series and various spectroscopic indicators show additional hints of variations at an approximate period of 21.1 d (and its first harmonic), which we attribute to the rotation period of the star.FEDER/ERF FICTS-2011-02 fundsMajor Research Instrumentation Programme

Discovery and mass measurement of the hot, transiting, Earth-sized planet, GJ 3929 b
We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180-18, TOI-2013). Joint modelling of photometric observations from TESS sectors 24 and 25 together with 73 spectroscopic observations from CARMENES and follow-up transit observations from SAINT-EX, LCOGT, and OSN yields a planet radius of Rb = 1.150 ± 0.040 R⊕, a mass of Mb = 1.21 ± 0.42 M⊕, and an orbital period of Pb = 2.6162745 ± 0.0000030 d. The resulting density of ρb = 4.4 ± 1.6 g cm−3 is compatible with the Earth’s mean density of about 5.5 g cm−3. Due to the apparent brightness of the host star (J = 8.7 mag) and its small size, GJ 3929 b is a promising target for atmospheric characterisation with the JWST. Additionally, the radial velocity data show evidence for another planet candidate with P[c] = 14.303 ± 0.035 d, which is likely unrelated to the stellar rotation period, Prot = 122 ± 13 d, which we determined from archival HATNet and ASAS-SN photometry combined with newly obtained TJO data
