Mortality in emergency departments (EDs) is not well known. This study aimed to assess the impact of the first-wave pandemic on deaths accounted in the ED of older patients with COVID and non-COVID ...diseases.
We used data from the Emergency Department and Elderly Needs (EDEN) cohort (pre-COVID period) and from the EDEN-COVID cohort (COVID period) that included all patients ≥65 years seen in 52 Spanish EDs from April 1 to 7, 2019, and March 30 to April 5, 2020, respectively. We recorded patient characteristics and final destination at ED. We compared older patients in the pre-COVID period, with older patients with non-COVID and with COVID-19. ED-mortality (before discharge or hospitalization) is the prior outcome and is expressed as an adjusted odds ratio (aOR) with 95% interval confidence.
We included 23,338 older patients from the pre-COVID period (aged 78.3 8.1 years), 6,715 patients with non-COVID conditions (aged 78.9 8.2 years) and 3,055 with COVID (aged 78.3 8.3 years) from the COVID period. Compared to the older patients, pre-COVID period, patients with non-COVID and with COVID-19 were more often male, referred by a doctor and by ambulance, with more comorbidity and disability, dementia, nursing home, and more risk according to qSOFA, respectively (p < 0.001). Compared to the pre-COVID period, patients with non-COVID and with COVID-19 were more often to be hospitalized from ED (24.8% vs. 44.3% vs. 79.1%) and were more often to die in ED (0.6% vs. 1.2% vs. 2.2%), respectively (p < 0.001). Compared to the pre-COVID period, aOR for age, sex, comorbidity and disability, ED mortality in elderly patients cared in ED during the COVID period was 2.31 (95% confidence interval CI: 1.76-3.06), and 3.75 (95% CI: 2.77-5.07) for patients with COVID. By adding the variable qSOFA to the model, such OR were 1.59 (95% CI: 1.11-2.30) and 2.16 (95% CI: 1.47-3.17), respectively.
During the early first pandemic wave of COVID-19, more complex and life-threatening older with COVID and non-COVID diseases were seen compared to the pre-COVID period. In addition, the need for hospitalization and the ED mortality doubled in non-COVID and tripled in COVID diagnosis. This increase in ED mortality is not only explained by the complexity or severity of the elderly patients but also because of the system's overload.
Treatment of acute pain in older patients is a common challenge faced in emergency departments (EDs). Despite many studies that have investigated chronic analgesic use in the elderly, data on ...patterns of acute use, especially in EDs, of analgesics according to patient characteristics is scarce.
To investigate sex- and age-related patterns of analgesic use in the Spanish EDs and determine differences in age-related patterns according to patient sex.
A secondary analysis of the Emergency Department and Elderly Needs (EDEN) multipurpose cohort.
Fifty-two Spanish EDs (17% of Spanish EDs covering 25% of Spanish population).
All patients' ≥65 years attending ED during 1 week (April 1-7, 2019). Patient characteristics recorded included age, sex, chronic treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and opiates, comorbidity, dependence, dementia, depression, ability to walk and previous falls. Analgesics used in the ED were categorized in three groups: non-NSAID non-opioids (mainly paracetamol and metamizole, PM), NSAIDs, and opiates.
Frequency of analgesic use was quantified, and the relationship between sex and age and analgesic use (in general and for each analgesic group) was assessed by unadjusted and adjusted logistic regression and restricted cubic spline models. Interaction between sex and age was explored.
We included 24 573 patients, and 6678 (27.2%) received analgesics in the ED: 5551 (22.6%) PM, 1661 (6.8%) NSAIDs and 937 (3.8%) opiates (1312 received combinations). Analgesics were more frequently used in women (adjusted OR = 1.076, 95%CI = 1.014-1.142), as well as with NSAID (1.205, 1.083-1.341). Analgesic use increased with age, increasing PM and decreasing NSAIDs use. Opiate use remained quite constant across age and sex. Interaction of sex with age was present for the use of analgesics in general ( P = 0.006), for PM ( P < 0.001) and for opiates ( P = 0.033), with higher use of all these analgesics in women.
Use of analgesics in older individuals in EDs is mildly augmented in women and increases with age, with PM use increasing and NSAIDs decreasing with age. Conversely, opiate use is quite constant according to sex and age. Age-related patterns differ according to sex, with age-related curves of women showing higher probabilities than those of men to receive any analgesic, PM or opiates.
In September 2015, the four-component, protein-based meningococcal serogroup B vaccine (4CMenB; Bexsero) became available for private purchase in Spain.
We conducted a nationwide matched case-control ...study to assess the effectiveness of 4CMenB in preventing invasive meningococcal disease in children. The study included all laboratory-confirmed cases of invasive meningococcal disease in children younger than 60 months of age between October 5, 2015, and October 6, 2019, in Spain. Each case patient was matched with four controls according to date of birth and province. 4CMenB vaccination status of the case patients and controls was compared with the use of multivariate conditional logistic regression.
We compared 306 case patients (243 79.4% with serogroup B disease) with 1224 controls. A total of 35 case patients (11.4%) and 298 controls (24.3%) had received at least one dose of 4CMenB. The effectiveness of complete vaccination with 4CMenB (defined as receipt of at least 2 doses, administered in accordance with the manufacturer's recommendations) was 76% (95% confidence interval CI, 57 to 87) against invasive meningococcal disease caused by any serogroup, and partial vaccination was 54% (95% CI, 18 to 74) effective. Complete vaccination resulted in an effectiveness of 71% (95% CI, 45 to 85) against meningococcal serogroup B disease. Vaccine effectiveness with at least one dose of 4CMenB was 64% (95% CI, 41 to 78) against serogroup B disease and 82% (95% CI, 21 to 96) against non-serogroup B disease. With the use of the genetic Meningococcal Antigen Typing System, serogroup B strains that were expected to be covered by 4CMenB were detected in 44 case patients, none of whom had been vaccinated.
Complete vaccination with 4CMenB was found to be effective in preventing invasive disease by serogroup B and non-serogroup B meningococci in children younger than 5 years of age.
A solution to the three-dimensional finite line-source (FLS) model for borehole heat exchangers (BHEs) that takes into account the prevailing geothermal gradient and allows arbitrary ground surface ...temperature changes is presented. Analytical expressions for the average ground temperature are derived by integrating the exact solution over the line-source depth. A self- consistent procedure to evaluate the in situ thermal response test (TRT) data is outlined. The effective thermal conductivity and the effective borehole thermal resistance can be determined by fitting the TRT data to the time- series expansion obtained for the average temperature.
Abstract
This article presents the adaptation of the MacArthur Communicative Development Inventory (CDI; Fenson et al., 1993, Guide and technical manual for the MacArthur Communicative Development ...Inventories. San Diego, CA: Singular Press; Fenson et al. 1994, Variability in early communicative development. Monographs of the Society for Research in Child Development, 59, 1–173) to Spanish Sign Language (LSE). Data were collected from 55 participants (32 boys and 23 girls; 17 deaf signers, 38 hearing signers) who, evaluated by their caregivers every 4 months, presented a total of 170 records. The parents reported the signs that the children could understand or produce between 8 and 36 months. Results suggested that the CDI adapted to LSE is a valid and reliable instrument. Signing children could understand more signs than they produced at this early developmental stage. There were no significant differences between boys and girls, or between deaf and hearing children. The development of LSE is similar to other sign languages, although with a lower production of signs in the early stages, perhaps due to the bilingualism of most of the children of our study.
To analyze the impact of the COVID-19 pandemic on Spanish emergency department (ED) care for patients aged 65 years or older during the first wave vs. a pre-pandemic period.
Retrospective ...cross-sectional study of a COVID-19 portion of the EDEN project (Emergency Department and Elder Needs). The EDEN-COVID cohort included all patients aged 65 years or more who were treated in 52 EDs on 7 consecutive days early in the pandemic. We analyzed care variables, discharge diagnoses, use of diagnostic and therapeutic resources, use of observation units, need for hospitalization, rehospitalization, and mortality. These data were compared with data for an EDEN cohort in the same age group recruited during a similar period the year before the pandemic.
The 52 participating hospital EDs attended 33 711 emergencies during the pandemic vs. 96 173 emergencies in the pre-COVID period, representing a 61.7% reduction during the pandemic. Patients aged 65 years or older accounted for 28.8% of the caseload during the COVID-19 period and 26.4% of the earlier cohort (P .001). The COVID-19 caseload included more men (51.0%). Comorbidity and polypharmacy were more prevalent in the pandemic cohort than in the earlier one (comorbidity, 92.6% vs. 91.6%; polypharmacy, 65.2% vs. 63.6%). More esturesources (analgesics, antibiotics, heparins, bronchodilators, and corticosteroids) were applied in the pandemic period, and common diagnoses were made less often. Observation wards were used more often (for 37.8% vs. 26.2% in the earlier period), and hospital admissions were more frequent (in 56.0% vs. 25.3% before the pandemic). Mortality was higher during the pandemic than in the earlier cohort either in ED (1.8% vs 0.5%) and during hospitalization (11.5 vs 2.9%).
The proportion of patients aged 65 years or older decreased in the participating Spanish EDs. However, more resources were required and the pattern of diagnoses changed. Observation ward stays were longer, and admissions and mortality increased over the numbers seen in the reference period.
The efficacy of self-measurement of capillary blood glucose (SMBG) in patients with type 2 diabetes mellitus is not fully established. The objectives of the study were: a) to verify the efficacy of ...the SMBG in patients with type 2 diabetes mellitus in the primary care set; b) to investigate the possible causes that explain the lack of effectiveness of the method, in their case, and c) to deduce the predictive variables that permit to select good utilizador of the SMBG.
Clinical trial controlled and randomized carried out in the environment of the primary care, on type 2 diabetic patients. The patients were assigned, of random form and stratified, according to the type of treatment for diabetes that received, in 2 groups: SMBG group (SMBG-G) and control group (CG). The period of monitoring was of 12 months. The efficacy of the SMBG was analyzed, and also its effectiveness.
100 patients were included in the study. Out of them, 51 were assigned to SMBG-G and 49 to CG. The SMBG was efficient in the 21.6% of SMBG-G and in 14.3% patients of the CG (p = 0.44). The SMBG efficacy was greater in patients with combined treatment and in those who received only insulin (50% in both cases). No improvement was observed in patients on treatment with diet (p = 0.006). The effectiveness for the cut off from value the HbA1c was of 59.2% and of 29.58% for the totality of the European criteria of metabolic control. The independent predictor variables of the SMBG efficacy were: the evolution years number of the diabetes mellitus and a deficient control of the illness at the start of the study. The global precision of the mathematical model obtained was of 88.24% with sensibility of 54.5%, especificity of 97.5%, positive predictor value of 85.7% and negative predictive value of 11.4% (p < 0.001). The area under the ROC curve was of 89.9% (p < 0.001) (95% confidence interval, 81.2-98.5%). According to the ROC curve, the point of cut that better the SMBG efficacy discriminated was that of 74% (sensibility: 72.7%; especificity: 77.5%).
SMBG is a tool that, although can improve the metabolic control of type 2 diabetes, requires a careful selection of patients and, therefore, cannot be utilized in an indiscriminate way. The time of evolution of the illness and fundamentally, the presence of a deficient metabolic control of the disease should be the factors that determine a good selection. Therefore, its extended use among the type 2 diabetic population, without a prior selection, does not seem to be justified.
•Levels of IL-6, IL-4 and IL-17 are slightly upregulated in fibromyalgia (FMS).•Immune-inflammatory and the compensatory (IRS/CIRS) phenotypes are also upregulated.•Research in immune-inflammatory in ...FMS needs to evaluate cofounding variables.•Immune-inflammatory studies in FMS need to focus on a wider spectrum of biomarkers.
The objective was to identify immune alterations in patients with fibromyalgia syndrome (FMS) compared to healthy controls (HC) using meta-analysis and meta-regression. Six electronic databases were searched for suitable original articles investigating immune biomarkers in FMS in comparison to HC. We extracted outcomes and variables of interest, such as mean and SD of peripheral blood immune biomarkers, age or sex. A random-effects model with restricted maximum-likelihood estimator was used to compute effect sizes (standardized mean difference and 95% CI, Hedges’ g) and meta-analysis, group meta-analysis and meta-regressions were conducted. Forty-three papers were included in this systematic review, of which 29 were suitable for meta-analysis. Interleukin (IL)-6 (g = 0.36 (0.09–0.63); I2 = 85.94; p = 0.01), IL-4 (g = 0.50 (0.03–0.98); I2 = 81.87; p = 0.04), and IL-17A (g = 0.53 (0.00–1.06); I2 = 87.15; p = 0.05), were significantly higher in FMS compared to HC while also combinations of cytokines into relevant phenotypes were significantly upregulated including M1 macrophage (g = 0.23 (0.03–0.43); I2 = 77.62; p = 0.02), and immune-regulatory (g = 0.40 (0.09–0.72); I2 = 84.81; p = 0.01) phenotypes. Heterogeneity levels were very high and subgroup and meta-regression analyses showed that many covariates explained part of the heterogeneity including medication washout, sex, time of blood sampling and exclusion of patients with major depressive disorder. In conclusion, FMS is accompanied by a disbalance between upregulated pro-inflammatory (M1 and Th-17) and immune-regulatory cytokines although effect sizes are small-to-moderate. Based on our results we provide specific methodological suggestions for future research, which should assess Th-1, Th-17, chemokines, and Th-2 phenotypes while controlling for possible confounding variables specified in this study.
Recent findings indicate that N2 fixation is significant in aphotic waters, presumably due to heterotrophic diazotrophs depending on organic matter for their nutrition. However, the relationship ...between organic matter and heterotrophic N2 fixation remains unknown. Here we explore N2 fixation in the deep chlorophyll maximum and underneath deep waters across the whole Mediterranean Sea and relate it to organic matter composition, characterized by optical and molecular methods. Our N2 fixation rates were in the range of those previously reported for the euphotic zone of the Mediterranean Sea (up to 0.43 nmol N L−1 d−1) and were significantly correlated to the presence of relatively labile organic matter with fluorescence and molecular formula properties representative for peptides and unsaturated aliphatics and associated with the presence of more oxygenated ventilated water masses. Finally, and despite that the aphotic N2 fixation contributes largely to total water column diazotrophic activity (>50%), its contribution to overall nitrogen inputs to the basin is negligible (<0.5%).
Key Points
Volumetric N2 fixation rates in aphotic waters were as high as previous euphotic rates
N2 fixation was higher in more ventilated and oxygenated waters containing fresher organic matter
Deep N2 fixation contributed largely to depth‐integrated rates and poorly to total nitrogen inputs
