Epidemiological and clinical characteristics of survivors of SARS-COV-2 infection: A descriptive study. / Características epidemiológicas y clínicas de sobrevivientes a infección por SARS-CoV-2: estudio descriptivo.

Introduction: In March 2020, the World Health Organization (WHO) declared a pandemic for coronavirus 19. Typical symptoms were fever, cough, asthenia, dyspnea, and muscle pain. Pulmonary and central nervous system compromise presented challenging characteristics for healthcare physicians. The objectives of this study were to identify epidemiological and clinical characteristics of SARS-COV-2 infection survivors in a region of Argentina and to determine differences between gender, age groups, year of infection, and evolution time since diagnosis. Methods: A descriptive and analytical cross-sectional observational study was carried out. A self-administered questionnaire was applied, which was available between August and December 2021. Results: Among 1868 individuals included, the mean age was 39.4 ± 13.9 years, and 72.8% were female. Arterial hypertension was the most frequent comorbidity (11.7%). The majority were outpatients (81.9%). The most frequent presentation symptoms at all ages were asthenia (83.7%), fever (54.9%), headache (60.8%), anosmia (64.8%), ageusia (53.2%), cough (54.4%) and myalgias (53.7%). For the 18 to 29 years old age group, the most prevalent presentation symptoms were: headache (69.4%), anosmia (69.1%), ageusia (60.2%), odynophagia (45%), and rhinitis/nasal congestion (46.9%). In the 30 to 64 years old age group, there was a higher prevalence of myalgias (55.8%), arthralgias (41%), and concentration/memory disorder (28.3%). Male showed higher prevalence of fever (64.9% versus 51.1%; p < 0.001) and pneumonia (23.5% versus 13.4%; p < 0.001). After 12 weeks from diagnosis, 38.1% of patients persisted with asthenia, 23.6% with anosmia/dysosmia, and 21.2% with concentration/memory disorders. Conclusions: Systemic symptoms were common to all age groups with coronavirus 19 disease; however, younger, and intermediate age groups presented a higher prevalence of central nervous system symptoms such as anosmia and cognitive disorders, respectively. Symptoms beyond 12 weeks of diagnosis reached slightly more than 10% of the participants.

Introducción: En marzo de 2020 la enfermedad por coronavirus 19 fue declarada pandemia por la Organización Mundial de la Salud. Los síntomas más comunes fueron fiebre, tos, astenia, disnea y dolor muscular. Los compromisos pulmonar y del sistema nervioso central presentaron características desafiantes para los médicos asistenciales. Los objetivos del estudio fueron conocer las características epidemiológicas y clínicas de sobrevivientes a infección por SARS-CoV-2 en una región de Argentina, y determinar las diferencias entre género, grupos etarias, año de contagio, tiempo de evolución desde el diagnóstico. Métodos: Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó un cuestionario auto administrado, que estuvo disponible entre agosto y diciembre de 2021. Resultados: La media de edad fue de 39,4 ± 13,9 años, el 72,8% fueron mujeres. La comorbilidad más frecuente fue hipertensión arterial (11,7%). La mayoría de los pacientes fueron ambulatorios (81,9%). Los síntomas de presentación más frecuentes a cualquier edad, fueron astenia (83,7%), fiebre (54,9%), cefalea (60,8%), anosmia (64,8%), ageusia (53,2%), tos (54,4%) y mialgias (53,7%). Para el grupo de 18 a 29 años los síntomas de presentación más prevalentes fueron cefalea (69,4%), anosmia 69,1%), ageusia (60,2%), odinofagia (45%) y rinitis/congestión nasal (46,9%). En el grupo de 30 a 64 años se observó mayor prevalencia de mialgias (55,8%), artralgias (41%), falta de concentración/memoria (28,3%). Los hombres mostraron más prevalencia de fiebre (64,9% versus 51,1%; p < 0,001) y neumonía (23,5% versus 13,4%; p < 0,001). Luego de las 12 semanas del diagnóstico 38,1% de los pacientes persistían con astenia, 23,6% con anosmia/disosmia y 21,2% con trastornos de concentración/memoria. Conclusiones: La enfermedad por coronavirus 19 presenta un patrón de síntomas sistémicos común a todos los grupos etarios. No obstante, los grupos más jóvenes presentan más prevalencia de síntomas de afección del sistema nervioso central como la anosmia y los grupos intermedios, mayor prevalencia de trastornos cognitivos. Los síntomas más allá de las 12 semanas del diagnóstico alcanzaron a algo más del 10% de los participantes.

Características Epidemiológicas del Tabaquismo en la Población estable de la Ciudad de Cipolletti, 2013-2014 / Epidemiological Characteristics of Tobacco Smoking in Citizens of the Cipolletti City, 2013-2014

INTRODUCCIÓN: El tabaquismo es la principal causa de muerte evitable en el mundo. En Argentina, el tabaco explica unas 40 000 muertes anuales, en su mayoría por enfermedades cardiovasculares, respiratorias y cáncer. La primera acción que propone la Organización Mundial de la Salud es el monitoreo, con el fin de obtener la información necesaria sobre la evolución de esta epidemia. OBJETIVOS: Conocer las características relacionadas con el hábito de fumar en la población estable de la ciudad de Cipolletti. MÉTODOS: Se realizó un estudio de corte transversal mediante una encuesta validada previamente. La población estuvo compuesta por mayores de 18 años con más de 10 años de residencia en la ciudad de Cipolletti. Se relevaron indicadores como: fumador actual, exposición al humo de tabaco ajeno, edad de comienzo del hábito y relación con otros factores de riesgo. RESULTADOS: El 57,2% (IC95%: 54,3- 60,1%) reconoció haber fumado alguna vez, y el 20,2% (IC95%: 17-23,9%) fumaba tabaco en el momento de la encuesta: 22,9% (IC95%: 18,9-27,3%) entre los hombres y 18,4% (IC95%: 15,5- 21,8%) entre las mujeres. La edad promedio de comienzo del hábito fue 17,8±7,8 años. CONCLUSIONES: Se observó una diferencia significativa de fumadores actuales frente a los reportes históricos tanto nacionales como regionales y provinciales. Este estudio aporta valiosa información para diseñar acciones de intervención en la población de la ciudad y probablemente de la región.

INTRODUCTION: Smoking is the leading cause of preventable death worldwide. In Argentina, smoking causes about 40,000 deaths annually, mostly from cardiovascular diseases, respiratory diseases and cancer. The first action proposed by the World Health Organization is monitoring in order to have the necessary information on the evolution of this epidemic. OBJECTIVES: To know the characteristics related to smoking habit in Citizens of Cipolletti City. METHODS: A cross-sectional study was carried out through a previously validated survey. The population was composed by people older than 18 living in Cipolletti for more than 10 years. The analyzed indicators were: current smoker, exposure to secondhand smoke, age at starting smoking and relationship with other risk factors. RESULTS: A total of 57.2% (CI95: 54.3-60.1%) of the population admitted having smoked at some point, and 20.2% (CI95: 17.0-23.9%) were current smokers at the time of the study: 22.9% (CI95: 18.9-27.3%) among men and 18.4% (CI95%: 15.5-21.8%) among women. The average age at starting smoking was 17.8±7.8 years. CONCLUSIONS: A significant difference in terms of current smokers was observed, comparing to historical reports at national, regional and provincial levels. This study provides valuable information to design interventions in the population of the city and probably the region.

Cribado para cáncer cervicouterino y de mama en la población femenina de la ciudad de cipolletti / Screening for cervix cancer and breast cancer in the female population of the city ofcipolletti

INTRODUCCIÓN: la detección precoz del cáncerde mama y cuello de útero en la mujer ha permitido aumentarla sobrevida y aun la curación en estas dos afecciones. Tanto lamamografía como la realización del Papanicolau (PAP) tienen unaadecuada sensibilidad y especificidad para la detección de tumoresincipientes. OBJETIVOS: conocer las prevalencias de utilizaciónde mamografía y PAP en la población femenina de la ciudad deCipolletti. MÉTODOS: Se realizó un estudio de prevalencia. Seincluyeron mujeres mayores de 18 años, no institucionalizadasy con más de 10 años de residencia. Los principales indicadoresfueron: realización de PAP y mamografía en los últimos dos años.RESULTADOS: Participaron del estudio 642 mujeres encuestadasefectivamente con edad promedio 50,24 +/-16,73 años y un rangoentre 18 y 91 años. El 76,7% (IC95%: 67,1-84,1%) de entre 50 y70 años había utilizado la mamografía, y el 74,9% (IC95%: 66,7-81,6%) de entre 25 y 65 se había realizado el Pap en los últimos 2años. Ambos indicadores resultaron mejores que en la Provinciade Río Negro. CONCLUSIONES: Si bien no todas las diferenciasdetectadas fueron estadísticamente significativas, se observa unatendencia a mayor prevalencia de realización de mamografía enCipolletti que en el resto de la provincia, la región y el país.

INTRODUCTION: early detection of breast cancer andcervix cancer in women has led to increased survival and evencure these diseases. Both mammography and Papanicolau (Pap)smear have adequate sensitivity and specificity for detection at earlystage these tumors. OBJECTIVES: To know the prevalence of use ofmammography and Pap smear in screening for breast cancer andcervix cancer in female population of the city of Cipolletti. METHODS:A cross sectional study was carried out. The population includedresidents of city of Cipolletti, older than 18 years, not institutionalizedand more than 10 years of residence. The main indicators wereperformed Pap smear and mammogram in the past two years.RESULTS: The study surveyed 642 women with an average age of50.24 +/- 16.73 years, with a range of age between 18 and 91 years.Mammogram was used in group included in current recommendationsin Argentina between 50 and 70 years in 76.7% (95% CI67.1% -84.1%) and Pap smear was used in 74.9% (CI95 % 66.7%-81.6%) of participants between 25 and 65 years, in the past 2years. Both indicators were better than they were in the Provinceof Río Negro. CONCLUSIONS: Although not all detected differencesare statistically significant, there is a higher use of mammographyin Cipolletti than in the province, the region and also the country.

Five-Year Outcomes after Off-Pump or On-Pump Coronary-Artery Bypass Grafting.

BACKGROUND: We previously reported that there was no significant difference at 30 days or at 1 year in the rate of the composite outcome of death, stroke, myocardial infarction, or renal failure between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report the results at 5 years (the end of the trial). METHODS: A total of 4752 patients (from 19 countries) who had coronary artery disease were randomly assigned to undergo off-pump or on-pump CABG. For this report, we analyzed a composite outcome of death, stroke, myocardial infarction, renal failure, or repeat coronary revascularization (either CABG or percutaneous coronary intervention). The mean follow-up period was 4.8 years. RESULTS: There were no significant differences between the off-pump group and the on-pump group in the rate of the composite outcome (23.1% and 23.6%, respectively; hazard ratio with off-pump CABG, 0.98; 95% confidence interval [CI], 0.87 to 1.10; P=0.72) or in the rates of the components of the outcome, including repeat coronary revascularization, which was performed in 2.8% of the patients in the off-pump group and in 2.3% of the patients in the on-pump group (hazard ratio, 1.21; 95% CI, 0.85 to 1.73; P=0.29). The secondary outcome for the overall period of the trial - the mean cost in U.S. dollars per patient - also did not differ significantly between the off-pump group and the on-pump group ($15,107 and $14,992, respectively; between-group difference, $115; 95% CI, -$697 to $927). There were no significant between-group differences in quality-of-life measures. CONCLUSIONS: In our trial, the rate of the composite outcome of death, stroke, myocardial infarction, renal failure, or repeat revascularization at 5 years of follow-up was similar among patients who underwent off-pump CABG and those who underwent on-pump CABG.

Effects of off-pump and on-pump coronary-artery bypass grafting at 1 year.

BACKGROUND: Previously, we reported that there was no significant difference at 30 days in the rate of a primary composite outcome of death, myocardial infarction, stroke, or new renal failure requiring dialysis between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report results on quality of life and cognitive function and on clinical outcomes at 1 year. METHODS: We enrolled 4752 patients with coronary artery disease who were scheduled to undergo CABG and randomly assigned them to undergo the procedure off-pump or on-pump. Patients were enrolled at 79 centers in 19 countries. We assessed quality of life and cognitive function at discharge, at 30 days, and at 1 year and clinical outcomes at 1 year. RESULTS: At 1 year, there was no significant difference in the rate of the primary composite outcome between off-pump and on-pump CABG (12.1% and 13.3%, respectively; hazard ratio with off-pump CABG, 0.91; 95% confidence interval [CI], 0.77 to 1.07; P=0.24). The rate of the primary outcome was also similar in the two groups in the period between 31 days and 1 year (hazard ratio, 0.79; 95% CI, 0.55 to 1.13; P=0.19). The rate of repeat coronary revascularization at 1 year was 1.4% in the off-pump group and 0.8% in the on-pump group (hazard ratio, 1.66; 95% CI, 0.95 to 2.89; P=0.07). There were no significant differences between the two groups at 1 year in measures of quality of life or neurocognitive function. CONCLUSIONS: At 1 year after CABG, there was no significant difference between off-pump and on-pump CABG with respect to the primary composite outcome, the rate of repeat coronary revascularization, quality of life, or neurocognitive function.

Off-pump or on-pump coronary-artery bypass grafting at 30 days.

BACKGROUND: The relative benefits and risks of performing coronary-artery bypass grafting (CABG) with a beating-heart technique (off-pump CABG), as compared with cardiopulmonary bypass (on-pump CABG), are not clearly established. METHODS: At 79 centers in 19 countries, we randomly assigned 4752 patients in whom CABG was planned to undergo the procedure off-pump or on-pump. The first coprimary outcome was a composite of death, nonfatal stroke, nonfatal myocardial infarction, or new renal failure requiring dialysis at 30 days after randomization. RESULTS: There was no significant difference in the rate of the primary composite outcome between off-pump and on-pump CABG (9.8% vs. 10.3%; hazard ratio for the off-pump group, 0.95; 95% confidence interval [CI], 0.79 to 1.14; P=0.59) or in any of its individual components. The use of off-pump CABG, as compared with on-pump CABG, significantly reduced the rates of blood-product transfusion (50.7% vs. 63.3%; relative risk, 0.80; 95% CI, 0.75 to 0.85; P<0.001), reoperation for perioperative bleeding (1.4% vs. 2.4%; relative risk, 0.61; 95% CI, 0.40 to 0.93; P=0.02), acute kidney injury (28.0% vs. 32.1%; relative risk, 0.87; 95% CI, 0.80 to 0.96; P=0.01), and respiratory complications (5.9% vs. 7.5%; relative risk, 0.79; 95% CI, 0.63 to 0.98; P=0.03) but increased the rate of early repeat revascularizations (0.7% vs. 0.2%; hazard ratio, 4.01; 95% CI, 1.34 to 12.0; P=0.01). CONCLUSIONS: There was no significant difference between off-pump and on-pump CABG with respect to the 30-day rate of death, myocardial infarction, stroke, or renal failure requiring dialysis. The use of off-pump CABG resulted in reduced rates of transfusion, reoperation for perioperative bleeding, respiratory complications, and acute kidney injury but also resulted in an increased risk of early revascularization.
