Background
Respiratory failure (RF) is the most important complication of influenza virus infection. Its definition and incidence are heterogeneous in the literature.
Methods
This systematic review ...and meta‐analysis aim to determine the incidence of and risk factors for RF in patients hospitalized with influenza. Electronic databases were searched for articles on RF in patients hospitalized for influenza infection up to December 2021 regardless of their geographical location. Observational and experimental studies were considered for inclusion, excluding case series. The Newcastle‐Ottawa and Johanna Briggs scales were used for quality assessment. A random‐effects meta‐analysis was performed, followed by subgroup analyses according to, among others, presence/absence of pneumonia, RF definition, serotype and time period. PRISMA guidelines were followed for this review.
Results
Thirty‐six studies were finally included in the meta‐analysis. Overall, RF incidence was 24% (range 5%–85%, 95% confidence interval 95CI 19%–31%). Significantly higher incidences of RF were found in patients with pneumonia (42%, 95CI 28%–57%, p = .006), when RF was defined as hypoxemia (58%, 95CI 31%–81%, p < .001), and during the 2009 pandemic (25%, 95CI 16%–36%) and postpandemic period (23%, 95CI 15%–34%, p = .01). No differences were found between human influenza serotypes. Assessment of risk factors associated with the development of RF was not possible due to their inconsistent and heterogeneous reporting.
Conclusion
Respiratory failure is frequent in hospitalized influenza patients, especially in patients with pneumonia and since the 2009 pandemic, although its definition and reporting widely vary in the literature. This complicates its characterization and comparison between cohorts and with other respiratory viruses.
The emergence or persistence of symptoms after acute SARS-CoV-2 infection has made it necessary to develop tools to detect them and assess their impact on patients' quality of life. One of these ...tools is the COVID-19 Yorkshire Rehabilitation Screening (C19-YRS) scale. We present the results of this tool in a cohort of first pandemic wave patients.
A cross-sectional study of patients with confirmed SARS-CoV-2 infection from March to May 2020 in Lugo (northwestern Spain). C19-YRS was administered via phone 10 months after the acute infection to both former inpatients and outpatients. Electronic medical records were reviewed and relevant data from the acute episode were collected. The main outcome was the presence of impairment in different areas measured by the C19-YRS scale.
The answer rate was 63.2%. The mean age was 54 ± 16 years, 38.4% were male and 190 (42.9%) had some comorbidity. Eighty-seven patients (19.6%) required hospitalization and 10 (2.3%) required intensive care unit admission. Ten (3.5%) patients lost their job due to the pandemic. Two hundred seventy-six patients (62.3%) related any symptoms; fatigue (37.2%) and exertional dyspnea (33.4%) were the most common with significant worsening in both cases compared with the situation before the infection. Subgroup analysis showed that more symptom domains were impaired in women than men. Older patients, those with comorbidity and those who needed hospital admission, demanded more health resources after the acute infection.
C19-YRS is useful for the detection and quantification of symptoms after COVID-19 and provides relevant social, health, and occupational information.
This systematic review and meta-analysis aim to provide scientific evidence regarding the effects of training on respiratory muscle training’s impact with the PowerBreath®. A systematic analysis ...based on the PRISMA guides and a conducted research structured around the bases of Web of Science, Scopus, Medline/PubMed, SciELO y Cochrane Library Plus. Six articles published before January 2021 were included. The documentation and quantification of heterogeneity in every meta-analysis were directed through Cochran’s Q test and the statistic I2; additionally, a biased publication analysis was made using funnel plots, whose asymmetry was quantified Egger’s regression. The methodological quality was assessed through McMaster’s. PowerBreath® administering a ≥ 15% resistive load of the maximum inspiratory pressure (PIM) achieves significant improvements (54%) in said pressure within 4 weeks of commencing the inspiratory muscle training. The maximal volume of oxygen (VO2max) considerable enhancements was achieved from the 6 weeks associated with the maximum inspiratory pressure ≥ 21.5% post inspiratory muscle training onwards. Conversely, a significant blood lactate concentration decrement occurred from the 4th week of inspiratory muscle training, after a maximum inspiratory pressure ≥ 6.8% increment. PowerBreath® is a useful device to stimulate sport performance and increase pulmonary function.
Smoking can play a key role in SARS-CoV-2 infection and in the course of the disease. Previous studies have conflicting or inconclusive results on the prevalence of smoking and the severity of the ...coronavirus disease (COVID-19).
Observational, multicenter, retrospective cohort study of 14,260 patients admitted for COVID-19 in Spanish hospitals between February and September 2020. Their clinical characteristics were recorded and the patients were classified into a smoking group (active or former smokers) or a non-smoking group (never smokers). The patients were followed up to one month after discharge. Differences between groups were analyzed. A multivariate logistic regression and Kapplan Meier curves analyzed the relationship between smoking and in-hospital mortality.
The median age was 68.6 (55.8-79.1) years, with 57.7% of males. Smoking patients were older (69.9 59.6-78.0 years), more frequently male (80.3%) and with higher Charlson index (4 2-6) than non-smoking patients. Smoking patients presented a worse evolution, with a higher rate of admission to the intensive care unit (ICU) (10.4 vs 8.1%), higher in-hospital mortality (22.5 vs. 16.4%) and readmission at one month (5.8 vs. 4.0%) than in non-smoking patients. After multivariate analysis, smoking remained associated with these events.
Active or past smoking is an independent predictor of poor prognosis in patients with COVID-19. It is associated with higher ICU admissions and in-hospital mortality.
This research is the single largest NR2E3 genotype-phenotype correlation study performed to date in autosomal dominant Retinitis Pigmentosa.
The aim of this study is to analyse the frequency of the ...p.Gly56Arg mutation in NR2E3 for the largest cohort of autosomal dominant Retinitis Pigmentosa patients to date and its associated phenotype.
A cohort of 201 unrelated Spanish families affected by autosomal dominant Retinitis Pigmentosa. The p.Gly56Arg mutation in the NR2E3 (NM_014249.2) gene was analysed in 201 families. In the 24 cases where the mutation had been detected, a haplotype analysis linked to the p.Gly56Arg families was performed, using four extragenic polymorphic markers D15S967, D15S1050, D15S204 and D15S188. Phenotype study included presence and age of onset of night blindness, visual field loss and cataracts; and an ophthalmoscopic examination after pupillary dilation and electroretinogram for the 24 cases.
Seven of the 201 analyzed families were positive for the p.Gly56Arg, leading to a prevalence of 3.5%. Clinical data were available for 24 subjects. Night blindness was the first noticeable symptom (mean 15.9 years). Visual field loss onset was variable (23.3 ± 11.9 years). Loss of visual acuity appeared late in the disease´s evolution. Most of the patients with cataracts (50%) presented it from the third decade of life. Fundus changes showed inter and intrafamiliar variability, but most of the patients showed typical RP changes and it was common to find macular affectation (47.4%). Electroretinogram was impaired from the beginning of the disease. Two families shared a common haplotype. Additionally, all patients shared a 104Kb region between D15S1050 and the NR2E3 gene.
This study highlights the importance of p.Gly56Arg in the NR2E3 gene as a common mutation associated with adRP, and provides new clues to its phenotype, which can allow for a better clinical management and genetic counselling of patients and their families.

To report 3 patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) who developed generalized myoclonus.
Patient data were obtained from medical records from the ...University Hospital "12 de Octubre," Madrid, Spain.
Three patients (2 men and 1 woman, aged 63-88 years) presented with mild hypersomnia and generalized myoclonus following the onset of the so-called inflammatory phase of coronavirus disease 2019 (COVID-19). All of them had presented previously with anosmia. Myoclonus was generalized with both positive and negative jerks, predominantly involving the facial, trapezius, sternocleidomastoid, and upper extremities muscles. These myoclonic jerks occurred spontaneously and were extremely sensitive to multisensory stimuli (auditive and tactile) or voluntary movements, with an exaggerated startle response. Other causes of myoclonus were ruled out, and none of the patients had undergone respiratory arrest or significant prolonged hypoxia. All of them improved, at least partially, with immunotherapy.
Our 3 cases highlight the occurrence of myoclonus during the COVID-19 pandemic as a post- or para-infectious immune-mediated disorder. However, we cannot rule out that SARS-CoV-2 may spread transneuronally to first- and second-order structures connected with the olfactory bulb. Further investigation is required to clarify the full clinical spectrum of neurologic symptoms and optimal treatment.
Although healthcare workers (HCWs) have reported mental health problems since the beginning of the COVID-19 pandemic, they rarely use psychological support. Here, we described the use of ...psychological support among HCWs in Spain over the 2-year period following the initial pandemic outbreak and explore its association with workplace- and COVID-19-related factors measured at baseline, in 2020.
We conducted a longitudinal study on HCWs working in Spain. We used an online survey to collect information on sociodemographic characteristics, depressive symptoms, workplace- and COVID-19-related variables, and the use of psychological support at three time points (2020, 2021, and 2022). Data was available for 296, 294, and 251 respondents, respectively at time points 1, 2, and 3.
Participants had a median age of 43 years and were mostly females (n = 242, 82%). The percentage of HCWs using psychological support increased from 15% in 2020 to 23% in 2022. Roughly one in four HCWs who did not use psychological support reported symptoms compatible with major depressive disorder at follow up. Baseline predictors of psychological support were having to make decisions about patients' prioritisation (OR 5.59, 95% CI 2.47, 12.63) and probable depression (wave 2: OR 1.12, 95% CI 1.06, 1.19; wave 3: OR 1.10, 95% CI 1.04, 1.16).
Our results suggest that there is call for implementing mental health promotion and prevention strategies at the workplace, along with actions to reduce barriers for accessing psychological support.
