Objective: to describe a patient with myocardial ischemia with multiple causes.

Clinical case: This clinical case describes a 58-year-old man with a history of hypertension, dyslipidemia, COPD and previous myocardial infarction (AMI). He went to the emergency room with chest pain and dyspnea. Findings included bibasal crackles, electrocardiogram with old anterior fibrosis, elevated NT-ProBNP, and echocardiogram with septoapical akinesia. During hospitalization, he experienced tachyarrhythmia and hemodynamic deterioration, undergoing electrical cardioversion (CVE). Non-ST segment elevation acute coronary syndrome (NSTEACS) complicated with ventricular arrhythmia and acute pulmonary edema was diagnosed. Coronary angiography revealed coronary ectasias without obstructive lesions, but with mild stenosis in three vessels. The patient was successfully treated with non-invasive ventilation, diuretics, vasodilators and anticoagulation. The discharge was granted with the plan to further studies to optimize and guide treatment and finally the diagnosis of Myocardial Infarction with Non-Obstructive Arteries (MINOCA) and the presence of coronary ectasias was addressed.

Conclusion: it is important to highlight the non-ischemic causes in MINOCA and the association between coronary ectasia and cardiovascular events, which is why we emphasize the need for more studies to better understand the relationship between these phenomena.

Introduction: COVID-19 vaccination aids pandemic limitation. In Argentina, three vaccines are approved, and healthcare workers are priorized (HCWs). The aim was to determine the effectiveness of COVID-19 vaccines, analyzing change in Immunoglobulin G levels and the incidence of new COVID-19 cases up to 12 months after the second dose.

Methods: Prospective cohort of HCWs between March 2021- 2022. COVIDAR IgG test was used to measure antibodies. A mixed-effects model was employed to compare the levels of immunoglobulin G at different time points, Kaplan Meier was used to estimate incident COVID-19 cases.

Results: 82 participants were included Adverse events were frequent but mild. All participant showed positive antibody at 12 months. Antibodies levels showed an increase one year after 2nd dose. Sinopharm took a long time to yield positive results. More than half of the people had mild COVID-19 disease.

Conclusion: COVID-19 vaccines are safe and effective.

Introduction: A progressive increase in the age of women at first pregnancy is observed, a situation that has been associated with a greater risk of adverse maternal and perinatal effects.

Objective: The aim of this study was to describe the characteristics and the maternal and perinatal outcomes of nulliparas of 40 years and older and compare them with those of nulliparas under 40.

Study design: This was a retrospective cohort analysis of a database of pregnancy population who had attended their deliveries in a private university hospital.

Results: An association was observed between maternal age ≥ 40 with the maternal compound adverse outcome (OR 1,3; 95% CI: 1,1-1,6), gestational diabetes (OR 3,6; 95% CI: 1,80-3,7), hypertensive disorders/preeclampsia (OR 2,2; 95% CI: 1,6-3,1) and postpartum hemorrhage (4,7; 95% CI: 1,2-16,3), with advanced maternal age persisting as an independent risk factor for the maternal compound adverse outcome (OR 1,3; 95% CI: 1,1 -1,6) and the perinatal compound adverse outcome (OR 1,40; 95% CI: 1,2-1,7) in the multivariate analysis. A higher rate of preterm birth was observed in the group of older nulliparas (OR 1,6; 95% CI: 1,3-2,0) with a higher requirement for admission to NICU for their newborns (OR 1,3; 95% CI: 1,0-1,8).

Conclusions: Women with advanced maternal age constitute a high-risk population, whose attention and follow-up would require a differential approach aiming to improve maternal and perinatal outcomes.

Medullary infarction is a severe and infrequent pathology, which represents 1% of all ischemic strokes, and is also a rare complication of different surgical procedures. It is caused by the acute interruption of the blood flow of the spinal cord, manifesting itself with clinical neurological deficits related to the affected vascular territory.

Methods: We present the case of an 80-year-old patient, with cardiovascular risk factors, who is present on post-surgical day 13, after placement of a vascular endoprosthesis for a thoracoabdominal aneurysm, sudden appearance of paraparesis with progression to paraplegia and hypoesthesia in both lower extremities. CT angiography of the aorta rules out local complications in the endoprosthesis. Medullary MRI showed images compatible with acute dorsal medullary infarction from level D9.

Results: On discharge, the patient presented paraplegia and hypoesthesia of both lower extremities with fecal and urinary incontinence.

Conclusion: Spinal cord infarction may be limited to a vascular territory or be more extensive according to its pathogenesis. The affectation of the anterior spinal artery is the most common and is characterized by bilateral motor deficits and loss of thermoalgesic sensitivity, which could have a great impact on the quality of life of patients. Its etiology is varied, including aortic surgery within its causes. MRI is very useful for its diagnosis and currently there are no clinical guides for the optimal treatment.

The objective of this study was to estimate the prevalence of diabetes mellitus (DM) and cardiovascular risk factors in a rural population in the province of San Luis, Argentina. Cross-sectional study developed between September and November 2017 with 18-year-old inhabitants and more than four towns in the Juan Martín de Pueyrredón department, San Luis. The participants answered questions by self-report on sociodemographic aspects, habits, psychosocial and risk factors for non-communicable diseases; physical measurements, FINDIRSC questionnaire and blood sample extraction were performed. Univariate estimates stratified by sex with their 95% confidence interval (95%CI) were obtained. We worked with sample expansion factors; crude and adjusted prevalences were calculated. The population consisted of 424 men (52.5%, 95%CI: 46.0-58.9) and 384 women (47.5%, 95%CI: 41.1-54.0). The adjusted prevalences for both sexes (by self-report) were: DM 11.8% (95%CI: 8.2-15.4); arterial hypertension (AHT): 35.5% (95% CI: 31.0-40.1); high cholesterol: 20.3% (CI 16.0-24.7). Males had significantly higher desirable HDL cholesterol and elevated blood pressure than females; women abdominal obesity in greater magnitude. 16.4% (95% CI: 11.0 - 23.6) had a high-very high risk of developing type 2 DM in the next 10 years. The adjusted prevalences of DM, hypertension, and high cholesterol were lower than those of the urban population of the province of San Luis. We highlight the pioneering contribution of this work to the knowledge of the health profile of rural communities in Argentina.

Introduction: Physical exercise has been shown to have a favorable impact on the health of the individual. Its combination with other healthy lifestyles can positively impact various areas, including sleep quality.

Objective: To determine the frequency of excessive daytime sleepiness in older adults of a municipal physical activity program in Santiago de Cali, Colombia.

Methodology: Cross-sectional study that included 605 older adults from a community program of the Secretary of Recreation and Sports of the City of Cali, Colombia, during October 2018 and June 2019. To determine the presence of excessive daytime sleepiness, the Epworth Sleepiness Scale was used.

Results: 81.5% of the population was female with a mean age of 73±8 years. The prevalence of excessive daytime sleepiness was 10.5%. Significant differences were only found in the frequency of excessive daytime sleepiness by socioeconomic stratum, being more common in the low socioeconomic stratum (13% vs 4% P=0.03).

Conclusion: Excessive daytime sleepiness is a phenomenon that affects older adults; however, its frequency may be lower in those who are physically active.

Introduction: During the COVID-19 pandemic, patients with worse evolution presented clinical deterioration 7-10 days after the onset of symptoms, which suggests that the inflammatory response could participate in the pathophysiology of the disease. The objective of this study was to evaluate the association between plasma C-reactive protein (PCr) on hospital admission and mechanical ventilation requirement during hospitalization in adults with COVID-19.

Methods: Retrospective, observational cohort at a private center in the province of Buenos Aires. Hospitalized adults diagnosed with COVID-19 by nasal swab using real time transcription polymerase chain reaction or antigen were included. The primary outcome was the association between high plasma PCr values on hospital admission (≥8 mg/L) and mechanical ventilation requirement during hospitalization.

Results: Of the 1,242 patients enrolled, 19.4% required mechanical ventilation and 11.7% died during the hospitalization. The PCr of the patients who required mechanical ventilation was higher than that of those who did not require mechanical ventilation (9.45 [5.20-18.70] mg/L vs 4.95 [1.80-10.70] mg/L; p < 0.01). PCr analyzed as a continuous variable (OR = 1.39; 95%CI 1.21-1.60; p < 0.001) and as a categorical variable (≥8 mg/L) (OR = 2.66; 95%CI 2.19 -3.78, p < 0.001) presented a significant association with the requirement of mechanical ventilation during hospitalization. Additionally, a significant association was found between PCr and in-hospital mortality.

Conclusion: Plasma PCr on hospital admission could predict clinical evolution in adult patients hospitalized for COVID-19.

Introduction: Simultaneous spinal stenosis in three regions of the spine is an unusual condition that demands proper clinical evaluation and imaging. Currently, there are no established guidelines for its diagnostic and therapeutic approach.

Objective: The objective of this study is to describe, based on a case report, the clinical presentation, treatment, and patient progression concerning triple stenosis, contrasting it with available evidence through a narrative review of the literature.

Case presentation: A 69-year-old woman presented with a progressive paraparesis accompanied by right sciatica and positive signs of upper motor neuron involvement. Imaging confirmed triple stenosis: cervical, dorsal, and lumbar. Dorsal decompression and tumor resection were performed in association with conservative treatment for cervical and lumbar stenosis, resulting in a favorable evolution one year post-surgery.

Conclusion: Symptomatic triple-region spinal stenosis is an unusual condition. Proper clinical and radiological assessments will enable accurate diagnosis and timely management.
