Aplicação de um método de interpolação físico-estatístico para a temperatura e pressão atmosférica sobre uma região de topográfica variável.

No presente trabalho os dados observados durante a campanha de campo de observações meteorológicas, associado à base de dados topográficos 3s-SRTM, foram utilizados para extrapolar as observações de temperatura do ar e pressão atmosférica para a região do Parque Nacional de Itatiaia (PNI). Para interpolação dos dados de temperatura e pressão sobre a área do PNI foram utilizados princípios físicos e estatísticos de interpolação. O método de interpolação pelo quadrado da distância utilizado juntamente com as outras equações físicas para estimar a temperatura do ar e a pressão atmosférica, sobre região do PNI, apresentou valores consistentes com os observados. Logo, o método pode ser empregado para a geração de mapas destas variáveis meteorológicas para regiões onde há baixa densidade de estações meteorológicas, em particular onde há acentuada variação topográfica

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Stop Hypertension with SLP/UCM I

El Proyecto Stop Hipertensión con ApS/UCM pretende aportar nuestro granito de arena a la lucha contra la hipertensión arterial (HTA), utilizando una herramienta educativa de aprendizaje en servicio (ApS), que permita a los estudiantes de los Grados en ciencias de la salud de la UCM aprender a la vez que realizan un servicio público. La hipertensión arterial (HTA) es un problema de salud pública y un importante factor de riesgo de padecer enfermedades cardiovasculares (ECV). Su diagnóstico está determinado por la medida de la presión arterial (PA) por lo que es de extrema importancia asegurar una medida fiable y válida. La automedida de la PA (AMPA) consiste en la medida de la PA por el propio paciente o un familiar, habitualmente en su domicilio, y es una herramienta útil para el diagnóstico y control de la HTA. Pero ¿sabemos medirnos de forma correcta la PA? ¿Usamos bien los tensiómetros? ¿Sabemos interpretar los registros de la PA y cuándo consultar al médico? Realizar AMPA correctamente no es fácil y exige un esfuerzo extraordinario de recursos humanos y económicos por parte de los profesionales de Atención Primaria. Por ello son necesarias nuevas estrategias para capacitar a la población en AMPA. Con este Proyecto nos proponemos luchar contra la HTA a través de la metodología educativa de aprendizaje-servicio que combina objetivos académicos con el servicio comunitario. El alumnado de los grados de Ciencias de la Salud de la UCM forman a la población en la correcta AMPA, asesorándoles sobre el uso correcto de los tensiómetros, enseñándoles a interpretar los resultados y alertándoles de cuándo acudir al médico. En el curso 2022-2023, el servicio público se ha dirigido principalmente al colectivo de mayores por ser especialmente vulnerables a padecer ECV en los Ayuntamientos de Coslada, Alcobendas y Alcorcón, y en las residencias Afanias y Neurovida, y a la población general que acuda a la Facultad durante la Semana de la Ciencia CAM/UCM 2022, a la Feria de la Salud de Coslada y a la campaña contra la HTA de la UCM junto con el Servicio de Medicina del Trabajo. Hemos demostrado que este proyecto es una herramienta rentable y efectiva en la lucha contra la HTA, vinculando la salud pública, los recursos de los ayuntamientos y la universidad. Se cubre así una necesidad y servicio social que podría salvar muchas vidas con recursos de bajo costo, cumpliendo con los objetivos del desarrollo sostenible y con los objetivos de la Sociedad Española de Hipertensión (SEH-LELHA) y de la estrategia HEARTS de la OPS/OMS. Los estudiantes se dan cuenta de la realidad de la Salud pública al tener contacto directo con la población, realizando un servicio a la sociedad, y desarrollándose profesionalmente.

International Impact of COVID-19 on the Diagnosis of Heart Disease

Background: The coronavirus disease 2019 (COVID-19) pandemic has adversely affected diagnosis and treatment of noncommunicable diseases. Its effects on delivery of diagnostic care for cardiovascular disease, which remains the leading cause of death worldwide, have not been quantified. Objectives: The study sought to assess COVID-19's impact on global cardiovascular diagnostic procedural volumes and safety practices. Methods: The International Atomic Energy Agency conducted a worldwide survey assessing alterations in cardiovascular procedure volumes and safety practices resulting from COVID-19. Noninvasive and invasive cardiac testing volumes were obtained from participating sites for March and April 2020 and compared with those from March 2019. Availability of personal protective equipment and pandemic-related testing practice changes were ascertained. Results: Surveys were submitted from 909 inpatient and outpatient centers performing cardiac diagnostic procedures, in 108 countries. Procedure volumes decreased 42% from March 2019 to March 2020, and 64% from March 2019 to April 2020. Transthoracic echocardiography decreased by 59%, transesophageal echocardiography 76%, and stress tests 78%, which varied between stress modalities. Coronary angiography (invasive or computed tomography) decreased 55% (p &lt; 0.001 for each procedure). In multivariable regression, significantly greater reduction in procedures occurred for centers in countries with lower gross domestic product. Location in a low-income and lower–middle-income country was associated with an additional 22% reduction in cardiac procedures and less availability of personal protective equipment and telehealth. Conclusions: COVID-19 was associated with a significant and abrupt reduction in cardiovascular diagnostic testing across the globe, especially affecting the world's economically challenged. Further study of cardiovascular outcomes and COVID-19–related changes in care delivery is warranted

Impact of COVID-19 on Diagnostic Cardiac Procedural Volume in Oceania: The IAEA Non-Invasive Cardiology Protocol Survey on COVID-19 (INCAPS COVID)

Objectives: The INCAPS COVID Oceania study aimed to assess the impact caused by the COVID-19 pandemic on cardiac procedure volume provided in the Oceania region. Methods: A retrospective survey was performed comparing procedure volumes within March 2019 (pre-COVID-19) with April 2020 (during first wave of COVID-19 pandemic). Sixty-three (63) health care facilities within Oceania that perform cardiac diagnostic procedures were surveyed, including a mixture of metropolitan and regional, hospital and outpatient, public and private sites, and 846 facilities outside of Oceania. The percentage change in procedure volume was measured between March 2019 and April 2020, compared by test type and by facility. Results: In Oceania, the total cardiac diagnostic procedure volume was reduced by 52.2% from March 2019 to April 2020, compared to a reduction of 75.9% seen in the rest of the world (p&lt;0.001). Within Oceania sites, this reduction varied significantly between procedure types, but not between types of health care facility. All procedure types (other than stress cardiac magnetic resonance [CMR] and positron emission tomography [PET]) saw significant reductions in volume over this time period (p&lt;0.001). In Oceania, transthoracic echocardiography (TTE) decreased by 51.6%, transoesophageal echocardiography (TOE) by 74.0%, and stress tests by 65% overall, which was more pronounced for stress electrocardiograph (ECG) (81.8%) and stress echocardiography (76.7%) compared to stress single-photon emission computerised tomography (SPECT) (44.3%). Invasive coronary angiography decreased by 36.7% in Oceania. Conclusion: A significant reduction in cardiac diagnostic procedure volume was seen across all facility types in Oceania and was likely a function of recommendations from cardiac societies and directives from government to minimise spread of COVID-19 amongst patients and staff. Longer term evaluation is important to assess for negative patient outcomes which may relate to deferral of usual models of care within cardiology
