COVID-19 New Cases and Environmental Factors During Wet and Dry Seasons in West and Southern Africa.

Sub-Saharan Africa has been the last continent to experience a significant number of cases in the novel Coronavirus (COVID-19). Studies suggest that air pollution is related to COVID-19 mortality; poor air quality has been linked to cardiovascular, cerebrovascular, and respiratory diseases, which are considered co-morbidities linked to COVID-19 deaths. We examine potential connections between country-wide COVID-19 cases and environmental conditions in Senegal, Cabo Verde, Nigeria, Cote D'Ivorie, and Angola. We analyze PM2.5 concentrations, temperatures from cost-effective in situ measurements, aerosol optical depth (AOD), and fire count and NO2 column values from space-borne platforms from 1 January 2020 through 31 March 2021. Our results show that the first COVID-19 wave in West Africa began during the wet season of 2020, followed by a second during the dry season of 2020. In Angola, the first wave starts during the biomass burning season but does not peak until November of 2020. Overall PM2.5 concentrations are the highest in Ibadan, Nigeria, and coincided with the second wave of COVID-19 in late 2021 and early 2022. The COVID-19 waves in Cabo Verde are not in phase with those in Senegal, Nigeria, and Cote, lagging by several months in general. Overall, the highest correlations occurred between weekly new COVID-19 cases meteorological and air quality variables occurred in the dry season.

Sex differences in treatment strategy for coronary artery aneurysms: Insights from the international Coronary Artery Aneurysm Registry.

INTRODUCTION: Sex disparities exist in coronary artery disease (CAD) in terms of risk profile, clinical management and outcome. It is unclear if differences are also present in coronary aneurysms, a rare variant of CAD. METHODS: Patients were selected from the international Coronary Artery Aneurysm Registry (CAAR; ClinicalTrials.gov: NCT02563626), and differences between groups were analysed according to sex. The CAAR database is a prospective multicentre registry of 1565 patients with coronary aneurysms (336 females). Kaplan-Meier method was used for event-free survival analysis for death, major adverse cardiac events (MACE: composite endpoint of death, heart failure and acute coronary syndrome) and bleeding. RESULTS: Female patients were older, were more often hypertensive and less frequently smoker. They were treated conservatively more often compared to male patients and received significantly less frequently aspirin (92% vs 88%, p = 0.002) or dual antiplatelet therapy (DAPT) (67% vs 58%, p = 0.001) at discharge. Median DAPT duration was also shorter (3 vs 9 months, p = 0.001). Kaplan-Meier analysis revealed no sex differences in death, MACE or bleeding during a median follow-up duration of 37 months, although male patients did experience acute coronary syndrome (ACS) more often during follow-up (15% vs 10%, p = 0.015). CONCLUSIONS: These CAAR findings showed a comparable high-risk cardiovascular risk profile for both sexes. Female patients were treated conservatively more often and received DAPT less often at discharge, with a shorter DAPT duration. ACS was more prevalent among male patients; however, overall clinical outcome was not different between male and female patients during follow-up.

Interference of Dermatophagoides pteronyssinus sensitization in grass pollen allergy.

Summary: Background. Climate conditions in the northwest of Spain are from the rest of the country, and the pollen sensitisation rates and allergens involved are different. The present study aimed to investigate the sensitisation profile of patients with grass pollen allergy and the interference of other sensitisations in respiratory symptoms. Methods. A total of 959 Spanish patients with seasonal respiratory symptoms and a positive skin prick test (SPT) to Phleum pratense pollen were studied. Patients were classified as having rhinitis and/or bronchial asthma. A battery of SPTs, including common weeds and tree pollens, profilin, polcalcin, moulds, Dermatophagoides pteronyssinus, Lepidoglyphus destructor, and cat and dog dander were performed. Serum specific IgE (sIgE) to Phl p 1 and Phl p 5, adding sIgE to Phl p 7, Phl p 12 and house dust mites (HDMs) or other pollens in selected cases were measured. Results.The majority (89.8%) of the patients were polysensitised according to SPT. HDM co-sensitisation was the most prevalent (62.3%). Profilin and polcalcin rendered a positive result in 25.9% and 18.7% of the patients, respectively. A higher proportion of patients recognized sIgE to Phl p 1 (88.7%) with respect to Phl p 5 (59%). Phl p 1-sIgE levels were higher than Phl p 5-sIgE levels, and no differences were found in patients with rhinitis and/or asthma. However, total serum IgE was higher in patients with asthma. Multivariate regression analyses revealed that only sIgE to Dermatophagoides pteronyssinus (after adjusting by sIgE to Phl p 1, Phl p 5 and Lepidoglyphus destructor) was associated with a greater risk of asthma. Conclusions. Phl p 1 is the most relevant allergen in patients with grass pollen allergy in the northwest of Spain. Sensitisation rates against panallergens are low. Even in patients with grass pollen allergy, HDM sensitisation plays a relevant role in asthma.

Anaphylaxis to Vespa velutina nigrithorax: Pattern of Sensitization for an Emerging Problem in Western Countries.

OBJECTIVE: To define the sensitization pattern of patients with anaphylaxis to Vespa velutina nigrithorax (VVN). METHODS: We studied 100 consecutive Spanish patients with anaphylaxis to Hymenoptera venom and systematically determined specific IgE (sIgE) to whole venoms (Vespula species, Polistes dominula, Apis mellifera, Vespa crabro, and Dolichovespula maculata) and their molecular components (rApi m 1, rApi m 5, rApi m 10, rVes v 1, rVes v 5, rPol d 5, and cross-reactive carbohydrates). Specific IgE to VVN venom and its antigen 5 (nVesp v 5) were measured in a subsample. RESULTS: Seventy-seven patients had anaphylaxis to VVN. Of these, only 16 (20.8%) reported previous VVN stings, but were stung by other Hymenoptera. Positive sIgE (>0.35 kUA/L) to each of the whole venoms was detected in >70% of patients (Vespula species in 100%). The components showing >50% positivity were rApi m 5 (51.4%), rPol d 5 (80.0%), and rVes v 5 (98.7%). This pattern was similar to that of Vespula species anaphylaxis (n=11) but different from that of A mellifera anaphylaxis (n=10). Specific IgE to nVesp v 5 was positive in all patients (n=15) with VVN anaphylaxis and was correlated with sIgE to both rVes v 5 (R=0.931) and rPol d 5 (R=0.887). CONCLUSIONS: VVN has become the commonest cause of Hymenoptera anaphylaxis in our area. Most cases report no previous VVN stings. Their sensitization pattern is similar to that of patients with anaphylaxis to other Vespidae. Specific IgE to antigen-5 from VVN, Vespula species, and P dominula are strongly correlated in patients with VVN anaphylaxis.

Primary Angioplasty in a Catastrophic Presentation: Acute Left Main Coronary Total Occlusion-The ATOLMA Registry.

OBJECTIVES: To determine the outcome predictors of in-hospital mortality in acute total occlusion of the left main coronary artery (ATOLMA) patients referred to emergent angioplasty and to describe the clinical presentation and the long-term outcome of these patients. BACKGROUND: ATOLMA is an uncommon angiographic finding that usually leads to a catastrophic presentation. Limited and inconsistent data have been previously reported regarding true ATOLMA, yet comprehensive knowledge remains scarce. METHODS: This is a multicenter retrospective cohort that includes patients presenting with myocardial infarction due to a confirmed ATOLMA who underwent emergency percutaneous coronary intervention (PCI). RESULTS: In the period of the study, 7930 emergent PCI were performed in the five participating centers, and 46 of them had a true ATOLMA (0.58%). At admission, cardiogenic shock was present in 89% of patients, and cardiopulmonary resuscitation was required in 67.4%. All the patients had right dominance. Angiographic success was achieved in 80.4% of the procedures, 13 patients (28.2%) died during the catheterization, and the in-hospital mortality rate was 58.6% (27/46). At one-year and at the final follow-up, 18 patients (39%) were alive, including four cases successfully transplanted. Multivariate analysis showed that postprocedural TIMI flow was the only independent predictor of in-hospital mortality (OR 0.23, (95% CI 0.1-0.36), p < 0.001). CONCLUSIONS: Our study confirms that the clinical presentation of ATOLMA is catastrophic, presenting a high in-hospital mortality rate; nevertheless, primary angioplasty in this setting is feasible. Postprocedural TIMI flow resulted as the only independent predictor of in-hospital mortality. In-hospital survivors presented an encouraging outcome. ATOLMA and left dominance could be incompatible with life.

Adaptación transcultural al castellano del Nursing Activities Score / Transcultural adaptation into Spanish of the Nursing Activities Score

Introducción La valoración de las cargas de enfermería es práctica habitual en el trabajo diario de los cuidados enfermeros, y normalmente se hace utilizando escalas ajenas al medio hispanoparlante, sin tener en cuenta las características de los distintos entornos que difieren de un país a otro. Entre los instrumentos utilizados para la valoración de las cargas de trabajo en enfermería en unidades de cuidados intensivos, Nursing Activities Score (NAS) ha sido descrito como un instrumento útil para medir dichas cargas en estas unidades. Objetivo Adaptar al castellano el NAS para su uso en unidades de cuidados intensivos. Material y métodos Adaptación por el método de traducción-retraducción del NAS mediante traductores de idioma materno inglés y bilingüe (castellano), y traductores con el castellano como idioma materno y alto nivel de inglés, trabajando los traductores por separado. Se obtuvo una versión única en castellano con la que se realizó una prueba piloto en la Unidad de Cuidados Intensivos y Grandes Quemados del Hospital Universitario de Getafe (Madrid, España) con 30 pacientes y 30 enfermeros durante su turno habitual de trabajo. Se consultó, también, con el autor principal del NAS los ítems que supusieron algún tipo de conflicto. Resultados Entre la escala original y la resultante de las retrotraducciones en inglés se obtuvo una buena correspondencia en el 73% de los ítems y una correspondencia apropiada en el restante 27%; ningún ítem fue considerado con correspondencia mala. Conclusión Se ha obtenido una versión adaptada en castellano del NAS (AU)

Introduction Assessment of nursing workload is a common practice in the daily work of nursing care. This is usually done using scales that were not designed for Spanish-speaking countries, which may not take into account the characteristics of the environments that differ from one country to another. The Nursing Activities Score (NAS) has been described as being a useful tool for measuring nursing workload among the instruments used for this measurement in intensive care units. Objective It was aimed to adapt the NAS into Spanish for its use in Spanish intensive care units. Material and methods The NAS was adapted using translation-back translation method with the participation of both native English speakers who were bilingual in Spanish, and Spanish translators with a high level of English. All of the translators worked individually. A single Spanish version of the scale was obtained, after which a pilot test was made in an Intensive Care Major Burns Unit of the University Hospital of Getafe (Madrid, Spain) with 30 patients and 30 nurses during their regular work shift. We also consulted the primary author of the original description of the NAS regarding items that caused some kind of conflict. Results Between the original scale and the result of the back-translations to English, we obtained agreement ratings of good in 73%, and appropriate in the remaining 27%. No item was considered to have bad correspondence. Conclusion We have developed a Spanish translation of the NAS that appears well matched to the original English version (AU)

Effects of IFN-γ, TNF-α, IL-10 and TGF-ß on Neospora caninum infection in rat glial cells.

Neospora caninum causes abortion in cattle and neurological disorders in dogs. The immunological response to this parasite has been described as predominantly of the Th1 type. However, infected primary glial cell cultures release IL-10 and IL-6 but not IFN-γ. This suggests a rather protective response of the glia to avoid inflammatory damage of the nervous tissue. In this study, we investigated the effects of pro-inflammatory cytokines in primary mixed cultures of rat astrocytes and microglia infected with N. caninum. The cells were treated with either IFN-γ, TNF-α, anti-IL-10 or anti-TGF-ß antibodies and were infected with parasite tachyzoites 24h later. Trypan Blue exclusion and MTT assays were performed to test cell viability. It was observed that cytokines, antibody treatment and in vitro infection did not reveal significant cell death in the various culture conditions. Treatment with 50, 150 and 300 IU/mL of either IFN-γ or TNF-α reduced tachyzoites numbers in cultures by 36.7%, 54.8% and 63.8% for IFN-γ and by 27.6%, 38.4% and 29.7% for TNF-α, respectively. In the absence of IL-10 and TGF-ß, tachyzoite numbers were reduced by 52.8% and 41.5%, respectively. While IFN-γ (150 and 300 IU/mL) increased the nitrite levels in uninfected cells, parasite infection seemed to reduce the nitrite levels, and this reduction was more expressive in IFN-γ-infected cells, thereby suggesting an inhibitory effect on its production. However, TNF-α, IL-10 and TGF-ß did not affect the nitrite levels. Basal PGE(2) levels also increased by 17% and 25%; 78% and 13% in uninfected and infected cells treated with IFN-γ or anti-TGF-ß, respectively. Nevertheless, the antibody neutralization of IL-10 reduced PGE(2) release significantly. These results highlight the possibility of a combined effect between the IFN-γ and parasite evasion strategies and show that the IFN-γ, TNF-α, IL-10 and TGF-ß cytokines participate in parasite proliferation control mechanisms.
