[Risk factors for mortality from COVID-19 Omicron variant: Retrospective analysis in elderly from the Canary Islands]. / Factores de riesgo asociados a fallecimiento por la variante ómicron de COVID-19: análisis retrospectivo con personas mayores de Canarias.

BACKGROUND AND AIMS: Since the beginning of the COVID-19 pandemic, the elderly population has had the highest rates of complications and mortality. This study aimed to determine the influence of different risk factors on deaths due to the Omicron variant in the Canary Islands. MATERIALS AND METHODS: A retrospective observational study of 16,998 cases of COVID-19 over 40 years of age was conducted in the Canary Islands between August 1, 2022, and January 31, 2023. We extracted sociodemographic data (age and sex) and clinical data (death, vaccination history, hospital admission, previous diseases, and treatments). RESULTS: Among the deaths, there was a higher proportion of males aged over 70 years, with diabetes, cardiovascular, renal, respiratory, and systemic diseases, and nursing home residents. Significant differences were observed in the number of doses of the vaccine. The multiple regression model showed that male sex (OR [95% CI]=1.92 [1.42-2.58]), age (70-79 years, 9.11 [4.27-19.43]; 80-89 years, 21.72 [10.40-45.36]; 90-99 years, 66.24 [31.03-141.38]; 100 years or older, 69.22 [12.97-369.33]), being unvaccinated (6.96, [4.01-12.08]), or having the last dose administered at least 12 months before the diagnosis (2.38, [1.48-3.81]) were significantly associated with mortality. CONCLUSIONS: Multiple factors may increase the risk of mortality due to COVID-19 in the elderly population. In our study, we found that only three predictors can effectively explain the variability: older age, male sex, and not being vaccinated or last vaccination date prior to one year.

COVID-19 long-term sequelae: Omicron versus Alpha and Delta variants.

BACKGROUND: The study aimed to assess the association between three predominant SARS-CoV-2 variants (Alpha, Delta, and Omicron) and the risk of developing long COVID (persistence of physical, medical, and cognitive symptoms more than 4 weeks after infection), post-COVID-19 syndrome (symptoms extending beyond 12 weeks), and viral persistence (testing positive beyond 4 weeks despite clinical resolution). METHODS: Retrospective study of 325 patients hospitalized for COVID-19 with genomic sequencing information. For each SARS-CoV-2 variant, sample characteristics, frequency of symptoms, and long-term sequelae were compared using Chi-squared test, Fisher's exact test, Kruskal-Wallis test, and Dunn's test as appropriate. Odds ratios (OR) were calculated using logistic regression models to assess the association of risk factors and sequelae. RESULTS: The adjusted model showed that the Omicron (vs Alpha) variant (OR, 0.30; 95% CI 0.16-0.56), admission to ICU (OR, 1.14; 95% CI 1.05-1.23), and being treated with antiviral or immunomodulatory drugs (OR, 2.01; 95% CI 1.23-3.27) predicted long COVID and post-COVID-19 syndrome. Viral persistence showed no difference between variants. CONCLUSIONS: The Omicron variant was associated with significantly lower odds of developing long-term sequelae from COVID-19 compared with previous variants, while severity of illness indicators increased the risk. Vaccination status, age, sex, and comorbidities were not found to predict sequelae development. This information has implications for both health managers and clinicians when deciding on the appropriate clinical management and subsequent outpatient follow-up of these patients. More studies with non-hospitalized patients are still necessary.

[Outbreak of monkeypox in the Canary Islands from may 15 to june 6, 2022]. / Estudio descriptivo del brote de viruela del simio en las Islas Canarias, mayo a octubre de 2022.

OBJECTIVE: Since May 2022, non-endemic countries reported the appearance of non-imported cases of monkeypox (Mpox). Spain was one of the most affected countries. The objective of the study was to describe the clinical-epidemiological characteristics of the first confirmed cases of Mpox in the Canary Islands and the main difficulties in contact tracing. METHODS: Retrospective observational descriptive study with confirmed cases of Mpox and their close contacts in the Autonomous Community of the Canary Islands. We conducted a descriptive analysis, using frequencies and percentages for qualitative variables, and median (interquartile range) for quantitative variables. RESULTS: One hundred and seventy-seven cases of Mpox were reported in the Canary Islands, with a median age of 39 years (32.8-48.3); 46.6% were HIV seropositive, and 6.8% were foreign. The most frequent clinical symptom was anogenital rash (68.8%), and at pustules stage (61.4%). One hundred and three declared risky sexual behaviors. Only fifty-three (30%) collaborated in the identification of close contacts. There were difficulties in: establishing communication with the cases, communicating the isolation measures, requesting tests, and due to delayed sample processing. CONCLUSIONS: Most common clinical symptom at diagnosis is anogenital rash in pustule stage. Most of the cases report risky sexual relations. The main barriers in contact tracing are the difficulty in contacting cases, the lack of identification data and the lack of experience of health professionals regarding Mpox.

OBJETIVO: Desde mayo de 2022, países no endémicos notificaron la aparición de casos no importados de viruela del simio (Mpox), siendo España uno de los más afectados. El objetivo del estudio fue describir las características clínico-epidemiológicas de los casos confirmados de Mpox en las Islas Canarias y las principales dificultades en el rastreo de contactos. METODOS: Se realizó un estudio retrospectivo observacional descriptivo con casos confirmados de Mpox y sus contactos estrechos en la Comunidad Autónoma de Canarias. Se realizó un análisis descriptivo, indicando frecuencias y porcentajes para variables cualitativas y mediana (rango intercuartílico) para cuantitativas. RESULTADOS: Se notificaron ciento setenta y siete casos de Mpox en las Islas Canarias, con una mediana de edad de 39 años (32,8-48,3), un 46,6% de seropositivos por VIH, y un 6,8% de extranjeros. La manifestación clínica más frecuente fue exantema anogenital (68,8 %), y en estadio de pústulas (61,4%). Ciento tres declararon conductas sexuales de riesgo. Solo cincuenta y tres (30%) colaboraron en la identificación de contactos estrechos. Se produjeron dificultades al establecer comunicación con los casos, al comunicar las medidas de aislamiento, en la solicitud de pruebas y, finalmente, debido al procesamiento de muestras con retraso. CONCLUSIONES: La manifestación clínica más frecuente al diagnóstico es el exantema anogenital en estadio de pústulas. La mayoría de los casos reportan relaciones sexuales de riesgo. Las principales barreras en el rastreo de contactos resultan la dificultad para contactar con los casos, la falta de datos de identificación y la inexperiencia de los profesionales sanitarios en relación con Mpox.

Atypical presentation of sexually-transmitted monkeypox lesions.

BACKGROUND: Typically, skin lesions caused by monkeypox (MPX) begin as a monomorphic exanthema with centrifugal distribution, and can be found at different sequential stages in different regions of the body. The aim of this study is to present an atypical case of MPX infection that simultaneously presented exanthema at three stages of evolution in the same location. METHODS: This is a descriptive study of a confirmed case of MPX by detection of the virus genome in clinical sample by polymerase chain reaction. RESULTS: We describe a 40-year-old male patient with an unusual clinical presentation. One week after having multiple risky MSM sexual intercourses, the patient developed skin eruption on the penis. During the following 10 days, he progressively developed new lesions on the same area. These lesions simultaneously showed different stages of evolution (vesicles, pustules and crust). CONCLUSIONS: Contrary to expected clinical presentation of the disease, the patient developed lesions at different stages in the same location. Attending physicians must be aware of atypical initial presentation and evolution of the lesions, and conduct a comprehensive epidemiological survey.

Developing a faster way to identify biocontamination in the air of controlled environment rooms with HEPA filters: airborne particle counting.

Our aim was to assess whether airborne particle counting is an immediate indicator of biocontamination in controlled environment rooms with HEPA filters in a hospital. A prospective study was carried out in a tertiary care hospital between 2016 and 2018. The study was divided in two periods and the measurements were performed in different controlled environment rooms with HEPA filters. The Environmental Biosafety Criterion (EBC) was defined as the absence of fungal and bacterial contamination. In the training period, the area under the ROC curve (aROC) of airborne particle counting and EBC was calculated for each particle size as well as the cut-off points that optimize the combination of sensitivity and specificity in the association between them. aROC is created by plotting sensitivity against 1-specificity. In the testing period, the cut-off points previously selected were validated. 328 measurements were carried out in the training period and 301 in the testing period. In the training period, an association was found between airborne particle counting and EBC. An aROC = 0.760, 95% Confidence Interval (95% CI) 0.695-0.825 was observed for 0.3 µm particles; an aROC = 0.797 (95% CI 0.734-0.860) for 0.5 µm particles; and an aROC = 0.751 (95% CI 0.673-0.829) for 5 µm particles. The cut-off points that optimized the combination of sensitivity and specificity were 9.0 × 103 for 0.3 µm particles, 3.6 × 103 particles for 0.5 µm, and 3.2 × 102 particles for 5 µm. In the testing period, the previous cut-off points were validated. We conclude that airborne particle counting is a useful, immediate, and preliminary measure to identify the presence of biocontamination in controlled environment rooms with HEPA filters.

Association between sleep characteristics and antihypertensive treatment in older adults.

AIM: The relationship between sleeping characteristics and antihypertensive medication is little known. We examined the association of sleep quality or duration and the use of sleeping pills with the number of antihypertensive drugs used in older adults. METHODS: This was a prospective cohort study of treated hypertensive patients aged ≥60 years participating in a seniors cohort, followed from 2008 to 2010 through 2012 to 2013. Self-reported sleep duration, sleep quality (usually having difficulty falling asleep or staying asleep) and sleeping pills use were ascertained at baseline, and the change in the number of antihypertensive drugs (active agents) between 2008-2010 and 2012-2013 was calculated. Analyses were carried out with logistic regression, and adjusted for demographics, lifestyle, comorbidity, baseline number of antihypertensive drugs and hypertension control. RESULTS: Among the 752 participants at baseline (mean age 69.9 years, 49.2% men), the mean sleep duration was 6.9 h/day, 37% had poor sleep quality, 16.5% usually consumed sleeping pills and the mean number of antihypertensive drugs was 1.8. During the follow-up period, 156 (20.7%) patients increased the number of antihypertensive drugs. No association was found between sleep duration or quality and the change in antihypertensive drug use. Usual sleeping pills consumption was associated with a higher risk of increasing (vs decreasing/maintaining) the number of antihypertensive drugs (odds ratio 1.85; 95% confidence interval 1.12-3.07, P-value 0.02). CONCLUSIONS: Consumption of sleeping pills was prospectively linked to an increased number of antihypertensive drugs. "Sleeping pill use" might be an indicator of future needs of antihypertensive treatment, and a warning indicator to investigate underlying sleep disorders or unhealthy lifestyles.

A New Surgical Site Infection Risk Score: Infection Risk Index in Cardiac Surgery.

Various scoring systems attempt to predict the risk of surgical site infection (SSI) after cardiac surgery, but their discrimination is limited. Our aim was to analyze all SSI risk factors in both coronary artery bypass graft (CABG) and valve replacement patients in order to create a new SSI risk score for such individuals. A priori prospective collected data on patients that underwent cardiac surgery (n = 2020) were analyzed following recommendations from the Reporting of studies Conducted using Observational Routinely collected health Data (RECORD) group. Study participants were divided into two periods: the training sample for defining the new tool (2010­2014, n = 1298), and the test sample for its validation (2015­2017, n = 722). In logistic regression, two preoperative variables were significantly associated with SSI (odds ratio (OR) and 95% confidence interval (CI)): diabetes, 3.3/2­5.7; and obesity, 4.5/2.2­9.3. The new score was constructed using a summation system for punctuation using integer numbers, that is, by assigning one point to the presence of either diabetes or obesity. The tool performed better in terms of assessing SSI risk in the test sample (area under the Receiver-Operating Characteristic curve (aROC) and 95% CI, 0.67/055­0.76) compared to the National Nosocomial Infections Surveillance (NNIS) risk index (0.61/0.50­0.71) and the Australian Clinical Risk Index (ACRI) (0.61/0.50­0.72). A new two-variable score to preoperative SSI risk stratification of cardiac surgery patients, named Infection Risk Index in Cardiac surgery (IRIC), which outperforms other classical scores, is now available to surgeons. Personalization of treatment for cardiac surgery patients is needed.

Combined Healthy Behaviors and Healthcare Services Use in Older Adults.

INTRODUCTION: Data on the combined impact of healthy behaviors on healthcare use in older adults are limited. METHODS: Study with community-dwelling individuals aged ≥60 years from the Spanish Seniors-ENRICA cohort, recruited in 2008-2010, followed through 2012-2013, and analyzed in 2016 (N=2,021). At baseline, the following healthy behaviors were self-reported: three traditional (never smoking, being physically active, having a healthy diet) and three emerging (sleeping 7-8 hours/day, sitting <8 hours/day, not living alone). Outcomes were self-reported polypharmacy (five or more drugs per day), primary care physician visits (one or more per month), medical specialist visits (more than one per year), and hospitalization (one or more in the last year). The associations between baseline healthy behaviors and healthcare services used in 2012-2013 were summarized with ORs and 95% CIs from multiple logistic regression, adjusting for demographics, lifestyles, comorbidities, and baseline health services used. RESULTS: Most single healthy behaviors were associated with lower use of most health services. Compared with participants with zero or one healthy behavior, those with five or six healthy behaviors showed lower risk of polypharmacy (OR=0.46, 95% CI=0.24, 0.85, p-trend=0.001), visits to the primary care physician (OR=0.50, 95% CI=0.26, 0.96, p-trend=0.013), and hospitalization (OR=0.50, 95% CI=0.24, 1.01, p-trend=0.016). No association was found with visits to the medical specialist. CONCLUSIONS: The combination of five to six healthy behaviors in older adults is associated with half the risk of polypharmacy and using several healthcare services. In an era of constrained resources in most countries, this information may help inform health policy to control healthcare spending in the future.
