ABSTRACT
Background: There are multisystemic consequences secondary to SARS- CoV-2 infection. Aim: To characterize neurological complications in patients admitted due to SARS-CoV-2 infection. Methods: Review of medical records of patients aged over 15 years with COVID-19 evaluated by the neurology team between April and August 2020 at a university hospital. Severity of the infection, referral reasons, neurological diagnoses and laboratory results were registered. The diagnoses were defined by consensus among the members of the hospital neurology group. Cerebrovascular and inflammatory diseases of the central and peripheral nervous system were defined as "probably associated" or "possibly associated" to COVID-19. Results: Ninety-six patients had at least 1 new neu- rological complication. 74% were admitted due to pneumonia and 20% due to a neurological disease. The most common reasons for neurological referral were impaired consciousness (39%), focal neurological deficit (24%), headache (9%) and seizures (5%). The most relevant neurological diagnoses were delirium in 48 patients, stroke in 24, critical illness polyneuropathy and myopathy in 17, seizures in 14, brachial plexopathy in 3, compressive neuropathies in 5, encephalitis in 1, possible vasculitis in 1 and Guillain-Barré syndrome in 1. Stroke and epilepsy were associated with increased length of hospital stay, but without differences in mortality. Conclusions: The spectrum of neurological complications of COVID-19 is wide. There are clinical entities typical of critically ill patients and also diseases associated directly and indirectly with the SARS-CoV2 infection.

RESUMEN: El objetivo del presente estudio es analizar los efectos de la actividad locomotriz voluntaria gestacional, como un tipo de entrenamiento físico, sobre la morfología de la bomba cardíaca de la cría, en modelo murino de la cepa CF-1. 12 hembras gestantes fueron divididas aleatoriamente en un grupo control y un grupo que realizó actividad locomotriz voluntaria, accediendo a una rueda de actividad durante los primero 12 días de gestación. Se evaluó la morfología cardiaca mediante cortes transversales, midiendo espesor y área de las paredes del ventrículo derecho, ventrículo izquierdo y septum, tanto en valores absolutos como en valores relativos a la masa corporal del individuo. Se observó que la masa corporal de las crías control (GC) fue significativamente mayor que las del grupo cuyas hembras accedieron a la rueda de actividad (GE) (p<0.01). Solo hubo diferencias en los valores absolutos de espesores y áreas miocárdicas de ventrículo derecho, entre el grupo GE y GC (p<0.05), pero al evaluar los espesores y áreas relativos a la masa corporal se observó que las crías del grupo GE presentaron espesores y áreas significativamente mayores que las que grupo GC (p<0.01). En conclusión, la actividad física gestacional altera el desarrollo morfológico de la bomba cardíaca en ratones CF-1, aumentando significativamente el espesor y área de las paredes miocárdicas en relación a la masa corporal total de la cría.
SUMMARY: The objective of the present study is to analyze the effects of gestational voluntary locomotor activity, as a type of physical training, on the morphology of the offspring´s heart pump, in a murine model of the CF-1 strain. Twelve (12) pregnant females were randomly divided in a control group and a group performing voluntary locomotor activity, by accessing an activity wheel during the first 12 days of gestation. Cardiac morphology was evaluated using cross sections, measuring thickness and area of the walls of the right ventricle, left ventricle, and septum, both in absolute values and values relative to the individual's body mass. It was observed that the body mass of the control pups (CG) was significantly higher than those of the group whose females accessed the activity wheel (GE) (p <0.01). Differences were observed only in absolute values of thickness and myocardial areas of the right ventricle, between the GE and GC group (p <0.05). However, when evaluating the thickness and areas relative to body mass, it was observed that the offspring of the GE group presented thicknesses and areas significantly larger than those in the GC group (p <0.01). In conclusion, gestational physical activity alters the morphological development of the heart pump in CF-1 mice, significantly increasing the thickness and area of the myocardial walls in relation to offspring total body mass.

Background: Molecular techniques for human papillomavirus (HPV) detection have a good performance as screening tests and could be included in cervical cancer early detection programs. We conducted a population-based trial comparing HPV detection and Papanicolaou as primary screening tests, in a public health service in Santiago, Chile. Aim: To describe the experience of implementing this new molecular test and present the main results of the study. Material and Methods: Women aged 25 to 64 enrolled in three public health centers were invited to participate. In all women, samples were collected for Papanicolaou and HPV DNA testing, and naked-eye visual inspection of the cervix with acetic acid was performed. Women with any positive screening test were referred to the local area hospital for diagnostic confirmation with colposcopy and biopsy of suspicious lesions. Results: Screening results were obtained for 8265 women, of whom 931 (11.3%) were positive to any test. The prevalence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was 1.1%; nine women had invasive cervical cancer. Sensitivities for the detection of CIN2+ were 22.1% (95% confidence interval (CI) 16.4-29.2) for Papanicolaou and 92.7% (95% CI 84.4-96.8) for HPV testing; specificities were 98.9% (95% CI 98.7-99.0) and 92.0% (95% CI 91.4-92.6) respectively. Conclusion: This experience showed that the implementation of a molecular test for cervical cancer screening is not a major challenge in Chile: it was well accepted by both the health team and the participants, and it may improve the effectiveness of the screening program.
