RESUMEN
Introduction: Continuous Positive Airway Pressure (CPAP) constitutes the most effective treatment for Obstructive Sleep Apnea (OSA). Automatic titration systems (ATS) are predominantly used to achieve adaptation to the equipment. Home CPAP devices allow telemonitoring (TM) of the same parameters as those provided by ATS but with access to continuous usage data. Under this premise, we conducted a study on the potential validity of TM for home CPAP devices as a titration system, its direct impact on proper adaptation (AD) to the equipment, and secondarily on the healthcare resources employed to achieve it. Material and methods: An observational study involving 318 patients with OSA who were titrated using TM to achieve AD to CPAP. Patients with OSA were consecutively recruited and evaluated at 1, 3, and 6 months after initiating treatment. Results were compared with a historical group of 307 patients with OSA who achieved AD to CPAP using ATS. Additionally, we assessed the impact on required healthcare resources. Results: Patients with OSA who initiated CPAP treatment with TM over the first six months showed a similar AD rate compared to the historical group titrated using ATS, with lower resource usage in the TM group. Conclusion: Data provided by TM of home CPAP devices allow for titration and achieving similar AD as with ATS in non-complex patients.
RESUMEN
Home Respiratory Therapies (HRT) encompass a variety of treatments for patients with chronic respiratory diseases, administered at home over extended periods. The Service Providers of HRT (SPHRT) collaborate with hospital resources to address chronic respiratory diseases, acting as strategic partners. The contracting of HRT in the public health system involves contests where the SPHRT present technical and economic offers. The purpose of this document is to provide a technical basis that can assist professionals, SPHRT, and the administration in making decisions when calling for, evaluating, and deciding on such contests.
RESUMEN
Chronic Obstructive Pulmonary Disease (COPD) constitutes a major public health problem, and it is anticipated that its prevalence will continue to increase in the future. Its progressive nature requires a continuous and well-coordinated care approach. The follow-up for COPD should primarily focus on disease screening and control, which includes monitoring of pulmonary function, prevention of exacerbations, identification of aggravating factors and comorbidities, as well as ensuring treatment adequacy and adherence. However, existing clinical practice guidelines and consensus documents offer limited recommendations for the follow-up. In this context, we undertake a review of COPD treatment and the continuity of care recommendations endorsed by several scientific societies. Moreover, we underscore the importance of the involvement of nursing and community pharmacy in this process, as well as the utilization of quality indicators in the provision of care for the disease.
RESUMEN
Introduction: The professional dedicated to respiratory health has an exemplary role in tobacco control, promoting smoking cessation in their patients. However, multiple circumstances cause a low implementation. Therefore, the objective of the study is to identify the consumption, knowledge and perception of tobacco and its emerging products in a representative sample of professionals involved in the treatment of respiratory patients integrated into the Spanish Society of Pneumology and Thoracic Surgery (SEPAR). Methods: Descriptive analysis of a structured online interview addressed to 5340 SEPAR members. Results: In a sample of 802 respondents, more than 33% have smoked at some time and 6.6% continue to smoke. More than 66% consider smoking as a chronic disease. More than 90% consider their role model important and advise their patients to quit smoking, but less than half carry out a smoking intervention. Only 35% of them believe that the ban on smoking in health centers is always complied. More than 75% do not consider nicotine delivery devices an option for smoking cessation or harm reduction. 22% are unaware of water pipes and 29% of heated tobacco. Conclusions: Professionals specialized in respiratory diseases are highly sensitized to smoking. Despite this, there are still weak points such as the insufficient implementation of smoking cessation interventions or the scant training in smoking and in new emerging products.
Introducción: El profesional dedicado a la salud respiratoria tiene un papel ejemplar en el control del tabaquismo, promoviendo el abandono del hábito tabáquico en sus pacientes. Sin embargo, múltiples circunstancias provocan una baja implementación. Por tanto, el objetivo del estudio es identificar el consumo, el conocimiento y la percepción sobre el tabaco y sus productos emergentes en una muestra representativa de profesionales implicados en el tratamiento de pacientes respiratorios integrados en la Sociedad Española de Neumología y Cirugía Torácica (SEPAR). Métodos: Análisis descriptivo de una entrevista estructurada en línea dirigida a 5.340 miembros de la SEPAR. Resultados: En una muestra de 802 encuestados, más del 33% ha fumado alguna vez y el 6.6% sigue fumando. Más del 66% considera el tabaquismo como una enfermedad crónica. Más del 90% considera importante su modelo a seguir y aconseja a sus pacientes que dejen de fumar, pero menos de la mitad realiza una intervención para dejar de fumar. Solo el 35% de ellos cree que la prohibición de fumar en los centros de salud se cumple siempre. Más del 75% no considera que los dispositivos de suministro de nicotina sean una opción para dejar de fumar o reducir los daños. El 22% desconoce las pipas de agua y el 29% el tabaco calentado. Conclusiones: Los profesionales especialistas en enfermedades respiratorias están altamente sensibilizados al tabaquismo. A pesar de ello, aún existen puntos débiles como la insuficiente implantación de intervenciones para dejar de fumar o la escasa formación en tabaquismo y en nuevos productos emergentes.
RESUMEN
PURPOSE: This study aimed to investigate hematological and cardiac changes after early (ECC) versus delayed cord clamping (DCC) in preterm infants at 24-34 weeks of gestation. METHODS: Ninety-six healthy pregnant women were assigned randomly to the ECC (< 10 s postpartum, n = 49) or DCC (45-60 s postpartum, n = 47). Primary endpoint was evaluation of neonatal hemoglobin, hematocrit and bilirrubin levels within the first 7 days after birth. A postpartum blood test was performed in the mother and a neonatal echocardiography in the first week of life. RESULTS: We found differences in hematological parameters during the first week of life. On admission, the DCC group had higher hemoglobin levels than the ECC group (18.7 ± 3.0 vs. 16.8 ± 2.4, p < 0.0014) and higher hematocrit values (53.9 ± 8.0 vs. 48.8 ± 6.4, p < 0.0011). Around day 7 of life, hemoglobin levels were also higher in the DCC group compared with the ECC group (16.4 ± 3.8 vs 13.9 ± 2.5, p < 0.005), as was the hematocrit (49.3 ± 12.7 vs 41.2 ± 8.4, p < 0.0087). The need of transfusion was lower in the DCC compared to the ECC (8.5% vs 24.5%; OR: 0.29, 95% CI: 0.09-0.97, p < 0.036). The need for phototherapy was also higher in the DCC (80.9% vs 63.3%; OR: 0.23, 95% CI: 0.06-0.84, p < 0.026). No differences in cardiac parameters or maternal blood tests. CONCLUSION: DCC improved neonatal hematological parameters. No changes in cardiac function were found and maternal blood loss did not increase to require transfusion.
RESUMEN
OBJECTIVE: To evaluate the diagnostic capacity of pulmonary angiography with multidetector computed tomography (MDCT) and iodine mapping in the diagnosis of pulmonary thromboembolism (PTE) in patients with Covid-19 disease. METHODS: Retrospective observational study of 81 consecutive patients admitted with Covid-19 respiratory infection who underwent MDCT for clinical suspicion of PTE (sudden dyspnea, chest pain, hemoptysis, severe respiratory failure (SRF) not corrected with high O2 flow) and/or raised D-dimer. RESULTS: Of the 81 patients studied [64 (79.01%) men], acute PTE was identified in 22 (27.16%), bilaterally in 13 (59.09%), and 13 (59,09%) showed areas of hypoperfusion. Of the 59 (72.83%) patients without PTE, hypoperfusion was observed in 41 (69.49%) (attributable in one case to pulmonary emphysema). In 18 (22.2%) of the total number of patients, neither PTE nor hypoperfusion were seen. A crazy paving pattern is a risk factor for developing PTE (OR 1.94; 95% CI 0.28-13.57), as are consolidations (OR 1.44; 95% CI 0.24-8.48) and septal thickening/bronchiectasis (OR 1.47; 95% CI 0.12-17.81).Patients with O2-refractory SRF showed a 6.36-fold higher risk for hypoperfusion on the iodine map. CONCLUSION: By adding the functional image to the anatomical image, pulmonary angiography with MDCT and iodine mapping can demonstrate not only PTE in main, lobar and segmental arteries, but also the presence of hypoperfusion in distal vessels. This makes it a highly useful tool for the accurate diagnosis and therapeutic orientation of patients with Covid-19 lung involvement.
RESUMEN
OBJECTIVES: In 2019 Chinese authorities alerted of the appearance of a cluster of cases of unknown pneumonia related to a new type of coronavirus. Spain is among the most affected countries. Our aim is to describe the cases of COVID-19 at Infanta Sofía University Hospital (Madrid), a public secondary hospital that increased its hospital beds to provide assistance during the outbreak. METHODS: Retrospective descriptive study of cases that met COVID-19 clinical diagnosis criteria or had a positive PCR test from February 27 to June 29, 2020. A description of demographic variables, hospital stay, mortality and the epidemiological curve was performed. RESULTS: Of 1,828 confirmed cases, 64.4% were hospitalised, 5.6% were admitted to the ICU. About 52.2% were male. The median age was 63.2 years. About 13.1% were nursing home residents. Nineteen percent were of Latin American origin of which 6.8% were admitted to the ICU. Overall case fatality was 14.6%. We observed a biphasic epidemiological curve. CONCLUSIONS: Sixty to 79-year-old males were admitted and deceased more often than women. Mortality reached 14.7%. Latin Americans were admitted more often to the ICU. Further studies about epidemiological characteristics of COVID-19 in hospitals are necessary.

Concerning the letter by Moriguchi et al., we describe our experience with a case of encephalopathy with and atypical damage on magnetic resonance imaging (MRI) in a patient with severe infection due to the SARS-CoV2 virus. A 56-year-old woman, without previous pathologies, developed cough, fever, and respiratory failure for five days, after returning from a 6-day trip to Venice. Chest radiography shows a large bilateral interstitial infiltrate. In the first 24 hours, she was admitted to the Intensive Care Unit (ICU) for severe respiratory failure and positive protein chain reaction-PCR in nasal exudate. She needed intubation for ten days. In the first 48 hours outside the ICU, she developed an acute confusional syndrome (hyperactive delirium). Neurological examination showed temporal-spatial disorientation and incoherent fluent speech. An electroencephalogram (EEG) showed generalized hypovoltaic activity. Cranial magnetic resonance imaging showed a bilateral and symmetrical increase in the supratentorial white matter's signal intensity, with a discrete thickening of both temporal lobes, with a slight increase in signal intensity and a sequence of normal diffusion. The lumbar puncture showed no changes (glucose 71 mg/dL, protein 30 mg/dL, 1 leukocyte). Within 72 hours of starting symptoms, she was neurologically asymptomatic. Our final diagnosis was an inflammatory encephalopathy related to a SARS-CoV2 infection.

OBJECTIVE: To compare the time in the third stage of labour, differences in maternal hematologic parameters 48h after birth and acid-base status in the umbilical cord between the early cord clamping (ECC) and delayed cord clamping (DCC). STUDY DESIGN: 97 healthy pregnancies at term and a spontaneous vertex delivery at Clinic University Hospital "Virgen de la Arrixaca" (Murcia, Spain), were randomized to ECC group (<10s post-delivery) or to DCC group (2min post-delivery). Duration of the third stage of labour was measured. Samples for acid-base status were taken both from the umbilical artery and vein. Blood samples were taken from the mothers 48h after birth. RESULTS: No statistical differences were found in the time of the third stage of labour (p=0.35). No statiscally significant differences were found between the number of red cells (p=0.25), hemoglobin (p=0.08) or hematocrit (p=0.15) in mothers. Umbilical acid-base status or gas analysis did not show any differences between the two groups CONCLUSIONS: Delayed cord clamping does not affect significantly the time of the third stage of labour. It does not show either any effect on the hematological parameters in the mother 48h after birth.

This study investigated ways of improving the usefulness of ~1700mL of poor-quality frozen semen collected from wild African elephant (Loxodonta africana) bulls. Ten semen samples from six bulls, frozen with 5% glycerol in Berliner cryomedium, with or without prior removal of the seminal plasma by centrifugation, were tested. All samples were subjected to the following density-gradient centrifugation treatments: no centrifugation (control), sham centrifugation, Percoll, OptiPrep, Isolate and PureSperm. Sample evaluation included motility, concentration, viability, acrosome integrity and normal morphology after thawing and after gradient centrifugation. Motility was also evaluated 3h after thawing. While all treatments were similar to the Control in acrosome integrity and normal morphology, significant differences were noted in concentration, viability and motility. Samples treated by Percoll showed the best motility, which was maintained unchanged over 3h of incubation (37°C). Correlations between manual and automated evaluations of concentration were high (cytometer; rho=0.92), but were lower for viability (cytometer; rho=0.57) and motility (computer-aided sperm analysis; rho=0.66). By performing density centrifugation, the quality of these sperm samples may be improved to a level suitable for artificial insemination in elephants. Although a sizeable proportion of cells are lost in the process, combining samples may still allow for multiple inseminations.
RESUMEN
The functionality of the placenta may affect neonatal adiposity and fetal levels of key nutrients such as long-chain polyunsaturated fatty acids. Fetal macrosomia and its complications may occur even in adequately controlled gestational diabetic (GDM) mothers, suggesting that maternal glycemia is not the only determinant of fetal glycemic status and wellbeing. We studied in vivo the placental transfer of fatty acids (FA) labeled with stable isotopes administered to 11 control and 9 GDM pregnant women (6 treated with insulin). Subjects received orally ¹³C-palmitic, ¹³C-oleic, and ¹³C-linoleic acids and ¹³C-docosahexaenoic acid (¹³C-DHA) 12 h before an elective caesarean section. FA were quantified by gas chromatography and ¹³C enrichments by gas chromatography-isotope ratio mass spectrometry. The ¹³C-FA concentration was higher in total lipids of maternal plasma in GDM patients versus controls, except for ¹³C-DHA. Moreover, ¹³C-DHA showed a lower placenta/maternal plasma ratio in GDM patients versus controls and a significantly lower cord/maternal plasma ratio. Other FA ratios studied were not different between GDM and controls. A disturbed ¹³C-DHA placental uptake occurred in GDM patients treated with diet or insulin, while the latter also had lower ¹³C-DHA levels in the venous cord. The tracer study pointed towards an impaired placental DHA uptake as a critical step, while the transfer of other ¹³C-FA was less affected. Patients with GDM treated with insulin could also have a greater fetal fat storage, which may have contributed to the reduced ¹³C-DHA in the venous cord observed. The DHA transfer to the fetus was reduced in GDM pregnancies compared to controls. This might have an influence on fetal neurodevelopment and long-term consequences for the child.

INTRODUCTION: The reason why there is a higher hospitalization rate due to asthma exacerbations amongst women is unclear. The objective of this study is to explore the possible causes that may explain this fact. METHODS: A multi-center, prospective study including asthma patients hospitalized in the pulmonary medicine departments during a two-year period. By means of a questionnaire, the following data were collected: demographic characteristics and treatment compliance, anxiety-depression, hyperventilation and asthma control, both prior to and during the hospitalization. RESULTS: 183 patients were included, 115 (62.84%) of whom were women. The women were older (52.4 ± 18.3/43.4 ± 18.7; P=.02), were more frequently prescribed inhaled corticosteroids (63.2%/47.1%; P=.03) and had a higher rate of hyperventilation syndrome (57.3/35.9; P=.02) and a longer mean hospital stay (7.3 ± 3.4/5.9 ± 3.6; P=.02). The percentage of smokers among the women was lower (21.2%/38.8%; p=0.01) and the FEV(1) was lower at admittance (58.2% ± 15.9/67.5% ± 17.4; P=.03). In the 40 to 60-year-old age range, an association was demonstrated between being female and the 'previous hospitalizations' variable (OR, 16.1; 95% CI, 1.6-156.7); sex and obesity were also independently associated (OR, 4.8; 95% CI, 1.06-22). CONCLUSIONS: In this cohort, the rate of hospitalization for asthma was higher in women than in men. Being a woman between the ages of 40 and 60 is associated with previous hospitalizations and is a risk factor for asthma-related hospitalization. This situation could partially be explained by the hormonal changes during menopause, where polyposis and obesity are independent risk factors.

Together with inflammation and subsequent remodeling of airways, an imbalance between oxidative and anti-oxidative agents is generated during the development of numerous pulmonary diseases. This process seems to be involved in both the pathogenesis and chronification of asthma, chronic obstructive pulmonary disease (COPD), SOAS, interstitial lung diseases and cystic fibrosis. Reactive oxygen species including superoxide anion, hidroxyl radicals and hydrogen peroxide (H2O2) are synthetised as a response of inflammatory cells and are responsible of the oxidation of nucleic acids, proteins and membrane lipids, leading to cell damage and enhanced inflammation. Until recently, it was difficult to quantify the airway production of reactive oxidative species (ROS). In fact, it has been only in the last few years when it has been possible to determine indirectly the levels of ROS in expired air and in tissue of asthmatic patients. The analysis of exhaled air is a single, reproducible and non-invasive technique which is useful in the study of volatile and non-volatile gases generated in different conditions. The determination of exhaled nitric oxide and carbon monoxide (CO) has a great usefulness in the assessment of asthma. Nitric oxide seems to be closely related to the physiopathology of asthma and COPD. In fact, it is correlated with the levels of sputum eosinophils and with the response to the treatment with steroids. Yet a correlation with the degree of airflow obstruction and the seriousness of the process has not been found. Exhaled CO is another indirect marker of inflammation and it is increased in asthma, COPD, cystic fibrosis and bronchectases. Even though numerous studies have shown its usefulness as a marker of inflammation and in the response to corticosteroids, its clinical application has limitations. In particular, it is not a specific and exclusive marker of oxidative stress and its levels are highly influenced by tobacco smoke. On the other hand, the association between exhaled CO and FEV1 is not clear and no relationship has been proved so far with the improvement of pulmonary function after steroid therapy and with the decrease of maximum expiratory flow at relapses. In this Review, we describe the advances in the knowledge of oxidative stress as a decisive factor in the pathogenesis of prevalent pulmonary diseases, as well as the methods allowing its analysis and monitoring.
