[Potentially useful drugs in the treatment of COVID-19 in Primary Care]. / Fármacos potencialmente útiles en el tratamiento de la COVID-19 en Atención Primaria.

The consequences of the SARS-CoV-2 pandemic have exceeded any forecast made. Today we know that the level of severity of the infection in its initial stages will correspond to the evolution and the presence of sequelae in the future. There are no specific treatments that have shown sufficient evidence to allow their recommendation, especially in the mild-moderate stages of the disease. The anti-Covid vaccination is showing clear benefits, both in the prevention of the disease and in its evolution, with the consequent improvement in the numbers of those affected by the pandemic. The use of different drugs used in other indications has been proposed as possible beneficial treatments for COVID-19 that, if used, will be prescribed individually taking into account the characteristics and situation of the patient, the evolutionary phase of the disease as well as well as the limitations of the lack of evidence in its administration.

[Pulse oximetry: Role in the COVID-19 patient at home]. / Pulsioximetría: papel en el paciente COVID-19 domiciliario.

COVID-19 behaves like a heterogeneous disease. Some patients may develop dyspnea-free hypoxemia during its evolution (silent hypoxemia). Pulse oximetry plays a crucial role in detecting hypoxemia in these patients, especially when they remain at home. Patients with SpO2 levels ≤ 92% or desaturations ≥ 3% after exercise test require hospital admission. Progressive saturation declines reaching SpO2 levels < 96% require strict clinical assessment (radiological study, blood test) for which it will be sent to a health center.

[Positioning for the management of arterial hypertension in Primary Care from the critical analysis of the American (2017) and European (2018) guidelines. Spanish Society of Primary Care Physicians (SEMERGEN)]. / Posicionamiento para el manejo de la hipertensión arterial en atención primaria a partir del análisis crítico de las guías americana (2017) y europea (2018). Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

The Scientific Societies of Primary Care, being the area in which there is a considerable prevalence of Arterial Hypertension (AHT), need to periodically evaluate the international guidelines for its management. This is particularly relevant when disparate guidelines make it difficult to make decisions in daily clinical practice. The present document has as its aim to analyse the changes and new developments proposed in the guidelines of the American College of Cardiology and the American Heart Association (ACC/AHA 2017), as well as in the guidelines of the European Society of Cardiology and European Society of Hypertension (ESC/ESH 2018). An analysis will be made of any differences, limitations, and their applicability to Primary Care in Spain. Finally, the most relevant available and appropriate information is extracted and integrated in order to homogenise the care of the hypertensive patient, from a critical, but also a reasoned, perspective. The discrepancies between the recommendations in such essential aspects as the management of the disease, require the compiling and critical analysis of the information that enables us as scientific society, interested in providing all PC physicians with the most relevant, and at the same time, sensible, recommendations of all the guidelines.
