Antecedentes: Hasta ahora, la pandemia de la enfermedad por coronavirus 2019 (COVID-19) ha afectado a más de 2,5 millones de individuos en todo el mundo, con aproximadamente 170.000 muertes. En la actualidad, no existen tratamientos con evidencias sólidas de beneficio clínico, y la utilización de agentes experimentales ha sido recomendada por las guías nacionales e internacionales como parte de los estudios clínicos. Método: En este estudio retrospectivo se incluyeron un total de 323 pacientes con síndrome respiratorio agudo severo por infección por COVID-19 documentada por PCR, ingresados en nuestra unidad. Los pacientes se clasificaron en dos grupos, según recibieran o no dosis elevadas de vitamina C intravenosa. Se examinó el efecto de la administración de dosis elevadas de vitamina C intravenosa, además de otros agentes utilizados habitualmente, sobre el pronóstico de los pacientes con neumonía por COVID-19. Resultados: En comparación con los pacientes que no recibieron vitamina C, los del grupo VC no fueron significativamente diferentes en cuanto a la duración de la estancia hospitalaria (p=0,05), la tasa de reingreso (p=0,943), el ingreso en cuidados intensivos, la necesidad de soporte avanzado de oxígeno (p=0,488), la necesidad de tratamiento médico avanzado (p <0,001) y la mortalidad (p=0,52). Conclusiones: Las limitadas evidencias basadas en muestras pequeñas impiden sacar conclusiones definitivas sobre la potencial eficacia de la vitamina C en dosis altas en estos pacientes, lo que indica la necesidad de una mayor evaluación en el contexto de la investigación clínica.

Magnesium deficiency is defined as a pathophysiologic factor in numerous illnesses. This study aims to define the effects of magnesium levels on patients in the intensive care unit (ICU) regarding length of stay in the ICU, length of mechanical ventilation (MV), and 28-day mortality. The following data were collected during initial assessment of patients admitted to the ICU with acute respiratory failure (ARF). Demographic data, magnesium and potassium levels, Charlson's Comorbidity Index (CCI), Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores, length of MV, length of hospital stay in the ICU, 28-day mortality, and ICU discharge status. In the initial serum analysis prior to treatment of patients in the ICU, the mortality rate of the patient group with hypermagnesemia was found to be statistically significant when compared with other magnesium levels ( P = .018). Apart from renal failure, ICU mortality is higher in the hypermagnesemia group than other groups. Hypermagnesemia is an electrolyte abnormality that is generally seen in older individuals and those with serious comorbidity and it can be used in mortality prediction.

OBJECTIVE: Failure to achieve high levels of medication adherence in obstructive lung diseases is a major cause of uncontrolled disease.The purpose of this study is to reveal clinicians' opinions on the level of patient adherence and the change in adherence during the COVID-19 pandemic.METHODS: A questionnaire containing multiple-choice questions about treatment adherence in patients with obstructive lung diseases was voluntarily applied to doctors working in a tertiary hospital for chest diseases.RESULTS: Eighty-one doctors (mean age, 37.2 years [standard deviation, 9.7 years]; 57 (70.4%) women) answered the questionnaires.Almost all clinicians participating in the study reported that they always or frequently asked patients if they adhered to treatment.Most clinicians think that in 20-50% of patients with asthma and less than 20% of patients with chronic obstructive pulmonary disease, a decrease in medication adherence appears in the first year of treatment. Most clinicians think the main reason for patients with obstructive lung diseases not adhering is patients' reluctance to be treated regularly. Regarding the impact of the COVID-19 pandemic on patients' drug adherence, 43.2% of clinicians observed that adherence increased after the start of the pandemic.CONCLUSION: Adherence to medication is not at the desired levels in patients with obstructive lung diseases. However, when faced with a serious health threat, such as the COVID-19 pandemic, patients realize the severity of their illness and begin using their treatments more regularly.

We aimed to determine the parameters that affect mortality in pulmonary intensive care units that are faster and inexpensive to determine than existing scoring systems. The relationship between serum osmolarity and prognosis was demonstrated for predialysis patients, in acute pulmonary embolism, heart failure, acute coronary syndrome, myocardial infarction, and acute spontaneous intracerebral hemorrhage in the literature. We hypothesized that serum osmolarity, which is routinely evaluated, may have prognostic significance in patients with respiratory failure.This study comprised 449 patients treated in the Pulmonary Intensive Care Clinic (PICU) of our hospital between January 1, 2020, and December 31, 2020. The modified Charlson Comorbidity Index (mCCI), Acute Physiology and Chronic Health Assessment (APACHE II), Sequential Organ Failure Evaluation Score (SOFA), Nutrition Risk Screening 2002 (NRS-2002), and hospitalization serum osmolarity levels were measured.Of the 449 patients included in the study, 65% (n = 292) were female and the mean age of all patients was 69.86 ± 1.72 years. About 83.1% (n = 373) of the patients included in the study were discharged with good recovery. About 4.9% (n = 22) were transferred to the ward because their intensive care needs were over. About 6.9% (n = 31) were transferred to the tertiary intensive care unit after their status deteriorated. About 5.1% (n = 23) died in the PICU. In the mortality group, APACHE II (P = .005), mCCI (P < .001), NRS-2002 total score (P < .001), and SOFA score (P < .001) were significantly higher. There was no statistically significant difference between the groups in terms of serum osmolarity levels.Although we could not determine serum osmolarity as a practical method to predict patient prognosis in this study, we assume that our results will guide future studies on this subject.
