Background: The usefulness of Lung Ultrasound (LUS) for the diagnosis of interstitial syndrome caused by COVID-19 has been broadly described. The aim of this study was to evaluate if LUS may predict the complications (hospital admission) of COVID-19 pneumonia in primary care patients. Methods: This observational study collects data from a cohort of 279 patients with clinical symptoms of COVID-19 pneumonia who attended the Balaguer Primary Health Care Area between 16 March 2020 and 30 September 2020. We collected the results of LUS scans reported by one general practitioner. We created a database and analysed the absolute and relative frequencies of LUS findings and their association with hospital admission. We found that different LUS patterns (diffuse, attenuated diffuse, and predominantly unilateral) were risk factors for hospital admission (p &lt, 0.05). Additionally, an evolutionary pattern during the acute phase represented a risk factor (p = 0.0019). On the contrary, a normal ultrasound pattern was a protective factor (p = 0.0037). Finally, the presence of focal interstitial pattern was not associated with hospital admission (p = 0.4918). Conclusion: The lung ultrasound was useful to predict complications in COVID-19 pneumonia and to diagnose other lung diseases such as cancer, tuberculosis, pulmonary embolism, chronic interstitial pneumopathy, pleuropericarditis, pneumonia or heart failure.

The effect of inhaled drugs in community-acquired pneumonia (CAP) is unclear. This case-control study was designed to determine whether inhaled drugs were risk factors for CAP. All incident cases of confirmed CAP that occurred over 1 yr in patients with chronic bronchitis (CB), chronic obstructive pulmonary disease (COPD) or asthma were included, as well as CB, COPD and asthma controls. Risk factors for CAP and inhaled treatment were recorded during a personal interview. An effect of inhaled drugs on the risk of CAP was observed in COPD and asthma patients after adjusting for the effect of other respiratory diseases and their concomitant treatments. In COPD patients, inhaled steroids had a risk OR of 3.26 (95% CI 1.07-9.98) and in asthma patients inhaled anticholinergics had a risk OR of 8.80 (95% CI 1.02-75.7). In CB patients, no association with CAP was observed for any inhaler. These effects were independent of adjusting variables related to severity and other respiratory and non-respiratory risk factors for CAP, including vaccines. Inhaled β(2)-adrenergic agonists did not show a significant effect on the risk of CAP in any of the respiratory diseases. Inhaled steroids may favour CAP in COPD patients, whereas anticholinergics may favour CAP in asthma patients. It is difficult to differentiate the effect of inhaled therapy from the effect of COPD or asthma severity on the risk of CAP, and these relationships may not be causal, but could call attention to inhaled therapy in COPD and asthma patients.

The aim of the present study was to identify risk factors for community-acquired pneumonia (CAP), with special emphasis on modifiable risk factors and those applicable to the general population. A population-based, case-control study was conducted, with a target population of 859,033 inhabitants aged >14 yrs. A total of 1,336 patients with confirmed CAP were matched to control subjects by age, sex and primary centre over 1 yr. In the univariate analysis, outstanding risk factors were passive smoking in never-smokers aged >65 yrs, heavy alcohol intake, contact with pets, households with >10 people, contact with children, interventions on the upper airways and poor dental health. Risky treatments included amiodarone, N-acetylcysteine and oral steroids. Influenza and pneumococcal vaccine, and visiting the dentist were protective factors. Multivariable analysis confirmed cigarette smoking, usual contact with children, sudden changes of temperature at work, inhalation therapy (particularly containing steroids and using plastic pear-spacers), oxygen therapy, asthma and chronic bronchitis as independent risk factors. Interventions for reducing community-acquired pneumonia should integrate health habits and lifestyle factors related to household, work and community, together with individual clinical conditions, comorbidities and oral or inhaled regular treatments. Prevention would include vaccination, dental hygiene and avoidance of upper respiratory colonisation.

Background and objective To analyze differences in the incidence of hip fracture in people older than 65 years in the 17 autonomous communities (AA. CC.) (regions) of the Spanish state in the 1997–2010 period. Material and methods Ecological, observational and retrospective study that includes people ≥ 65 year old who have suffered a hip fracture in Spain over 14 years. These records are taken from the minimum basic data set of patients treated in all hospitals of Spain. Results The analysis include 534,043 hip fractures in ≥ 65 year olds (414,518 women and 119,525 men). A percentage of 85.4 of hip fractures occurred in people ≥ 75 years (86.7% women; 80.7% men). The adjusted hip fracture rate/100,000/year was 722.6 in women and 284.8 in men. AA. CC. with women above the average of the country were 7, including Catalonia, Comunidad Valenciana and Castilla-La Mancha. Six AA. CC. had patients below the average, including Canary Islands and Galicia. In AA. CC. with highest and lowest adjusted hip fracture rate/100,000/year, the difference was 44% lower in women (Canary vs. Castilla-La Mancha) and 50% lower in men (Galicia vs. Catalonia). Conclusions The analysis of the incidence of hip fracture in Spain in people ≥65 year old shows a significant variability between AA. CC. Except in Canary Islands, this variability is difficult to explain only by factors such as population age, sun exposure or north-south gradient. Additional studies are needed to analyze the causes of these important differences between Spanish AA. CC.

Background: The WHO has recently published the FRAX tool to determine the absolute risk of osteoporotic fracture at 10 years. This tool has not yet been validated in Spain. Methods/design: A prospective observational study was undertaken in women in the FRIDEX cohort (Barcelona) not receiving bone active drugs at baseline. Baseline measurements: known risk factors including those of FRAX and a DXA. Follow up data on self-reported incident major fractures (hip, spine, humerus and wrist) and verified against patient records. The calculation of absolute risk of major fracture and hip fracture was by FRAX website. This work follows the guidelines of the STROBE initiative for cohort studies. The discriminative capacity of FRAX was analyzed by the Area Under Curve (AUC), Receiver Operating Characteristics (ROC) and the Hosmer-Lemeshow goodness-of-fit test. The predictive capacity was determined using the ratio of observed fractures/expected fractures by FRAX (ObsFx/ExpFx). Results: The study subjects were 770 women from 40 to 90 years of age in the FRIDEX cohort. The mean age was 56.8 ± 8 years. The fractures were determined by structured telephone questionnaire and subsequent testing in medical records at 10 years. Sixty-five (8.4%) women presented major fractures (17 hip fractures). Women with fractures were older, had more previous fractures, more cases of rheumatoid arthritis and also more osteoporosis on the baseline DXA. The AUC ROC of FRAX for major fracture without bone mineral density (BMD) was 0.693 (CI 95%; 0.622-0.763), with T-score of femoral neck (FN) 0.716 (CI 95%; 0.646-0.786), being 0.888 (CI 95%; 0.824-0.952) and 0.849 (CI 95%; 0.737-0.962), respectively for hip fracture. In the model with BMD alone was 0.661 (CI 95%; 0.583-0.739) and 0.779 (CI 95%; 0.631-0.929). In the model with age alone was 0.668 (CI 95%; 0.603-0.733) and 0.882 (CI 95%; 0.832-0.936). In both cases there are not significant differences against FRAX model. The overall predictive value for major fracture by ObsFx/ExpFx ratio was 2.4 and 2.8 for hip fracture without BMD. With BMD was 2.2 and 2.3 respectively. Sensitivity of the four was always less than 50%. The Hosmer-Lemeshow test showed a good correlation only after calibration with ObsFx/ExpFx ratio. Conclusions: The current version of FRAX for Spanish women without BMD analzsed by the AUC ROC demonstrate a poor discriminative capacity to predict major fractures but a good discriminative capacity for hip fractures. Its predictive capacity does not adjust well because leading to underdiagnosis for both predictions major and hip fractures. Simple models based only on age or BMD alone similarly predicted that more complex FRAX models.

Background The development of FRAX ® has been useful to simplify the fracture risk assessment of patients, although several studies have shown that this tool underestimates the real risk of fracture in Spanish population. Objectives To develop an accurate model of fracture risk assessment based on FRAX ®, using a cohort of Spanish women followed over a 10 year period and to establish the best thresholds for indication of DXA and indication of treatment (high-risk patients). Methods Longitudinal multicenter study. Women between 40-90 years from FRIDEX cohort (35,000 people in the Barcelona with DXA and extensive questionnaire on risk factors for fracture at baseline), who had been followed during a 10 year period and who had not received any treatment for osteoporosis were selected. New self-reported osteoporotic fractures contrasted with electronic records or clinical reports were collected.The risk of major osteoporotic fracture for Spanish population based on FRAX was assessed in all women. We calculated the Area Under the ROC curve (AUC) for both DXA and 10-year risk of major fracture by FRAX. Results We selected 816 women, mean age 56.8±8.2 years. After 10 years, 76 women (9.3%) had suffered 95 osteoporotic fractures, of which 49 (6%) were major (15 hip, 4 vertebral, 13 humerus and 17 distal radio). Women who suffered a major osteoporotic fracture during the follow-up were significantly older (p 7.5%). In women with intermediate risk the model reassess the probability of fracture including the T-score of femoral neck by DXA in the FRAX tool and classify these patients as low or high risk for fracture. The application of this model could save 82% of DXA scans and avoid up to 31% of unnecessary treatments. Conclusions The FRIDEX model, compared with DXA based model, has a better discriminative ability to detect women who will suffer osteoporotic fractures over a 10-year period. This model could save unnecessary DXA and osteoporotic treatments. Disclosure of Interest R. Azagra Grant/Research support from: Sponsored by FEDER, IS Carlos III Grant.

Background: The COVID-19 pandemic rapidly strained healthcare systems worldwide. The reference standard for diagnosis is a positive reverse transcription polymerase chain reaction (RT-PCR) test, but results are not immediate and sensibility is variable. Aim: To evaluate the diagnostic accuracy of lung ultrasound compared to chest X-ray for COVID-19 pneumonia. Design and Setting: A retrospective analysis of symptomatic patients admitted into one primary care centre in Spain between March and September 2020. Method: Patients’ chest X-rays and lung ultrasounds were categorized as normal or pathologic. RT-PCR confirmed COVID-19 infection. Pathologic lung ultrasound images were further categorized as showing either local or diffuse interstitial disease. McNemar and Fisher tests were used to compare diagnostic accuracy. Results: Most of the 212 patients presented fever at admission, either as a standalone symptom (37.74% of patients) or together with others (72.17% of patients). The positive predictive value of the lung ultrasound was 90% for the diffuse interstitial pattern and 46.92% for local pattern. The lung ultrasound had a significantly higher sensitivity (82.75%) (p &lt, 0.001), but lower specificity (71%) than the chest X-ray (54.02% and 86%, respectively) (p = 0.008) for identifying interstitial lung disease. Moreover, sensitivity of the lung ultrasound for severe interstitial disease was 100%, and was significantly higher than the chest X-ray (58.33%) (p = 0.002). Conclusion: The lung ultrasound is more accurate than the chest X-ray for identifying patients with COVID-19 pneumonia and it is especially useful for those presenting diffuse interstitial disease.

Introducción: Numerosos estudios han establecido tanto la hipertensión arterial como la hipertensión de bata blanca como factores de riesgo cardiovascular. Un ritmo circadiano anómalo de la presión arterial podría aumentar el riesgo cardiovascular. Objetivo: Determinar la existencia de una relación clínicamente relevante entre un ritmo circadiano anómalo de la presión arterial y un incremento del riesgo cardiovascular en pacientes con hipertensión arterial o hipertensión de bata blanca. Material y Método: Estudio descriptivo en 166 pacientes mayores de 18 años del Área Básica de Salud de Balaguer que tuvieran una monitorización ambulatoria de la presión arterial realizada entre junio de 2014 y marzo de 2018 y cumplieran los criterios de inclusión y exclusión. Se realizó un análisis univariado y bivariado de las variables. Resultados: Se obtuvo que en casi todos los promedios de presión arterial nocturna destaca el patrón riser mostrando que el 25% tenía un riesgo cardiovascular mayor o igual al 10%, seguido del dipper extremo 16,67%, dipper 9,4% y no dipper 8,27%. Conclusión: Un ritmo circadiano alterado se relaciona con un riesgo cardiovascular más elevado y un peor control de los factores que conllevan al mismo.
