RESUMO
Systemic sclerosis (SSc) is an autoimmune disease characterized by systemic inflammation, endothelial dysfunction, generalized fibrosis and high cardiovascular mortality. The evaluation of cardiovascular risk through the visceral adiposity index (VAI) has been helpful due to its direct relationship to the body and visceral fat percentage. We evaluated the influence of body composition and anthropometrics on cardiovascular risk as measured by VAI in healthy controls (HC) and SSc. An analytical cross-sectional study of 66 participants (33 SSc and 33 HC), mean age 52.7 ± 10, 95% women, was conducted from August 2020 to January 2021. Inclusion criteria in cases were consecutive patients with SSc (ACR/EULAR 2013), 63.6% were diffuse cutaneous (dcSS) subtype, and 36.4 were limited cutaneous (lcSS) subtype. HC was matched by age and gender. Serum lipid profiles and InBody anthropometrics were analyzed and compared. We performed descriptive statistics, bivariate analysis with Student's t, or Mann-Whitney U, correlation and chi-square according to the variable type and distribution. Total cholesterol was significantly higher in SSc than HC (345 vs 194, p = < 0.001). The BMI was higher in HC (26.2 vs 28.9, p < 0.001). Kilograms of muscle (19.8 vs 28.9, p < 0.001) and total fat (23.4 vs 28.9, p < 0.001) were lower in SSc patients compared to HC. VAI was similar when BMI < 25, but significantly higher when BMI > 25 in SSc than in HC (3 vs 1.9, p = 0.030). The increase in BMI at overweight or obese in SSc is associated with a significant increase in cardiovascular risk.

Systemic lupus erythematosus (SLE) is a disease that affects the immune system, and it can lead to increased morbidity and mortality. The primary causes of mortality for individuals with SLE are disease activity, infections, drug toxicity, and other health conditions. The aim of this study is to estimate the mortality rate of patients with SLE who are hospitalized, describe the causes of death, and identify factors associated with mortality. The study was conducted at a referral hospital from 2009 to 2021, utilizing a nested case-control design. The records of patients with SLE who were hospitalized in the Department of Rheumatology were reviewed. Cases were identified as individuals who died during their hospitalization, while controls were those who were discharged alive during the same period. Elective hospitalizations were not included in the study. The primary causes of death were recorded, and demographic, clinical, laboratory, and immunological variables were analyzed as potential risk factors associated with in-hospital mortality. The study included 105 patients who died while hospitalized and 336 who were discharged alive. The estimated mortality rate was 10.93 deaths per 1000 hospital admissions per year. The leading causes of death were SLE activity (20%), infections (34.2%), or a combination of both (24.8%). Risk factors associated with in-hospital mortality were any infection (OR 2.5, CI 95% 1.2-5.2), nosocomial infections (OR 5.0, CI 95% 1.8-13.7), SLEDAI-2K > 2 (OR 2.0, CI 95% 1.02-3.8), lymphopenia (OR 2.1, CI 95% 1.01-4.6), anemia (OR 2.9, CI 95% 1.4-5.7), and thrombocytopenia (OR 3.3, CI 95% 1.7-6.4). Disease activity and infections, particularly nosocomial infections, are significant causes of mortality in hospitalized patients with SLE. Furthermore, hematological manifestations play a significant role in in-hospital mortality for these patients.
RESUMO
Monkeypox is a viral zoonosis from the Poxviridae family that spreads at an unprecedented rate. It is transmitted through contact with skin lesions, respiratory droplets, body fluids, and sexual contact. The diverse presentation of the disease leads to misdiagnosis. Thus, clinicians should have a high index of suspicion, mainly with diseases with skin lesions. The most vulnerable group to developing this disease are individuals with risky sexual relationships, sexually transmitted infections, or human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). To date, only one case of coinfection with the monkeypox virus, syphilis, and HIV has been reported; however, no cases have been revealed in the Mexican territory. Herein we describe an unusual case of syphilis-monkeypox coinfection in an immunocompromised patient; despite his coinfection, he had a favorable prognosis. Furthermore, we attach allusive pictures of the natural evolution of dermatological lesions.
RESUMO
Background: Adequate glycemic control improves the prognosis of patients hospitalized for pneumonia associated with severe COVID-19. Objective: To evaluate the impact of hyperglycemia (HG) on the prognosis of patients hospitalized for severe pneumonia associated with COVID-19 in unvaccinated patients. Material and methods: Prospective cohort study. We included patients hospitalized from August 2020 to February 2021, with severe COVID-19 pneumonia, not vaccinated against SARS-CoV-2. Data was collected from admission to discharge. We used descriptive and analytical statistics according to the data distribution. ROC curves were used to determine the cut-off points with the highest predictive performance for HG and mortality, with the IBM SPSS program, version 25. Results: We included 103 patients, 32% women, 68% men, age 57 ± 13 years; 58% were admitted with HG (191, IQR 152-300 mg/dL) and 42% with normoglycemia (NG < 126 mg/dL). Mortality was higher in HG at admission 34 (56.7%) than in NG 13 (30.2%) (p = 0.008). HG was associated with diabetes mellitus 2 and neutrophilia (p < 0.05). The risk of death increases 1.558 times (95% CI 1.118-2.172) if HG is at admission and 1.43 times (95% CI 1.14-1.79) during hospitalization. Maintaining NG throughout the hospitalization contributed independently to survival (RR = 0.083 [95% CI 0.012-0.571], p = 0.011). Conclusion: HG significantly impacts prognosis by increasing mortality more than 50% during hospitalization for COVID-19.
Introducción: el adecuado control glucémico mejora el pronóstico de pacientes hospitalizados por neumonía asociada a COVID-19 grave. Objetivo: evaluar el impacto de la hiperglucemia (HG) sobre el pronóstico de pacientes hospitalizados por neumonía grave asociada a COVID-19 en no vacunados. Material y métodos: estudio de cohorte prospectivo. Se incluyeron pacientes hospitalizados de agosto de 2020 a febrero de 2021, con neumonía grave por COVID-19, no vacunados contra SARS-CoV-2. Los datos fueron recolectados desde el ingreso hasta el egreso. Se empleó estadística descriptiva y analítica de acuerdo con la distribución de datos. Se construyeron curvas ROC para determinar los puntos de corte de mayor rendimiento predictivo para HG y mortalidad, con el programa IBM SPSS, versión 25. Resultados: se incluyeron 103 pacientes, 32% mujeres, 68% hombres, edad 57 ± 13 años; 58% ingresaron con HG (191, IQR 152-300 mg/dL) y 42% en normoglucemia (NG < 126 mg/dL). La mortalidad fue mayor en HG al ingreso 34 (56.7%) que en NG 13 (30.2%) (p = 0.008). La HG se asoció con diabetes mellitus 2 y neutrofilia (p < 0.05). El riesgo de muerte se incrementó 1.558 veces (IC 95% 1.118-2.172) si la HG fue al ingreso y 1.43 veces (IC 95% 1.14-1.79) durante la hospitalización. Mantener NG durante todo el internamiento contribuyó de manera independiente a la sobrevida (RR 0.083 [IC 95% 0.012-0.571], p = 0.011). Conclusión: la HG impacta significativamente el pronóstico al incrementar en más de 50% la mortalidad durante la hospitalización por COVID-19.

Backround: Venous thromboembolic disease (VTED) is a frequent cause of hospitalization and mortality. Whole blood viscosity (WBV) participates in the pathogenesis of thrombosis. Objective: To identify the most frequent etiologies and their association with WBV index (WBVI) in hospitalized patients with VTED. Material and methods: Observational, cross-sectional, retrospective, analytical study, Group 1: cases (patients diagnosed with VTED) and Group 2: controls without thrombosis. Risk factors for VTED were described and WBVI was calculated from total proteins and hematocrit. Descriptive and inferential statistics were used with Chi-squared test, Fisher's exact test, Mann Whitney U test, bivariate and multivariate logistic regression analysis. Results: We included 146 patients and 148 controls, age 46.3 ±17.7 vs. 58 ± 18.2 years, of both sexes (female, 65.1%). The most frequent etiology was neoplastic (23.3%), followed by diseases with cardiovascular risk (17.8%). Independent risk factors for VTED were age, chronic kidney disease, presence of liver disease or solid neoplasia. WBVI was similar in patients with VTED as in those without thrombosis. We found an association of the presence of deep vein thrombosis and diseases with cardiovascular risk (p = 0.040). Conclusions: The presence of chronic kidney disease, liver disease, and solid neoplasia are independent risk factors for VTED. The WBVI is a simple and rapid diagnostic tool in the evaluation of patients with VTED.
Introducción: la enfermedad tromboembólica venosa (ETEV) es causa frecuente de hospitalización y mortalidad. La viscosidad sanguínea participa en la patogénesis de la trombosis. Objetivo: analizar los factores de riesgo y el índice de viscosidad sanguíneo total (IVTS) en pacientes con ETEV. Material y métodos: estudio observacional, transversal, retrospectivo, analítico. Grupo 1: casos (pacientes con diagnóstico de ETEV), y grupo 2: controles sin trombosis. Se describieron los factores de riesgo para ETEV y se calculó el IVTS a partir de proteínas totales y hematocrito. Se utilizó estadística descriptiva e inferencial con prueba de Chi cuadrada, prueba exacta de Fisher, U de Mann Whitney, análisis de regresión logística bivariado y multivariado. Resultados: incluimos 146 pacientes y 148 controles, edad 46.3 ± 17.7 frente a 58 ± 18.2 años, de ambos sexos, femenino (65.1%). La etiología más frecuente fue la neoplásica (23.3%), seguida de la enfermedad con riesgo cardiovascular (17.8%). Los factores de riesgo independientes para ETEV fueron: edad, enfermedad renal crónica, presencia de hepatopatía o neoplasia sólida. El IVTS fue similar en los pacientes con ETEV que en aquellos sin trombosis. Se encontró asociación de la presencia de trombosis venosa profunda y enfermedades con riesgo cardiovascular (p = 0.040). Conclusiones: la presencia de ERC, hepatopatía y neoplasia sólida son factores de riesgo independientes para ETEV. El IVTS es un instrumento diagnóstico sencillo y rápido en la evaluación de los pacientes con ETEV.

Background: COVID-19 brought with it unknowns related to systemic sclerosis. Objective: To know the clinical evolution and prognosis of COVID-19 in a cohort of patients with systemic sclerosis. Methods: During the pandemic, we had digital contact with a cohort of 197 patients with SSc. If they had any condition that met the suspected definition of COVID-19, they underwent polymerase chain reaction testing for SARS-CoV-2; they were treated on an outpatient or hospital basis without interfering with their treatment. They followed their evolution every 24 hours until they became asymptomatic or died. Results: Thirteen patients (6.6%), nine diffuse cutaneous (dcSSc), and four limited cutaneous (lcSSc) developed COVID-19 during nine months of follow-up. The immunosuppressants used at the time of the disease were: mycophenolate mofetil, methotrexate, and prednisone, in low doses. Seven patients had interstitial lung disease (ILD). The main symptoms were chest pain, cough, dyspnea, dysgeusia, and anosmia, 1 with mild symptoms without pneumonia, 11 with mild pneumonia, and one with severe pneumonia that required hospital management. Only one (7.7%) presented severe pneumonia, was hospitalized, and died. Conclusions: COVID-19 disease in patients with SSc can be overcome in most cases, even when they are ILD and were using immunosuppressants at the time of infection with the SARS-CoV-2 virus.
Introducción: la COVID-19 trajo consigo incógnitas relacionadas con la esclerosis sistémica, enfermedad de baja prevalencia asociada a neumopatía intersticial difusa (NID). Objetivo: conocer la evolución clínica y el pronóstico de la COVID-19 en una cohorte de pacientes con esclerosis sistémica (ES). Métodos: se analizó una serie de 13 casos procedentes de una cohorte de 197 pacientes con ES en seguimiento vía digital. Cuando los pacientes cumplieron con la definición sospechosa de COVID-19 se solicitó prueba de reacción en cadena de polimerasa para SARS-CoV-2. Todos los pacientes recibieron seguimiento durante su atención ambulatoria u hospitalaria, sin interferir con su tratamiento cada 24 horas hasta quedar asintomáticos o fallecer. Resultados: de 197 pacientes, trece (6.6%) enfermaron de COVID-19 de edad 57 años (RIC: 52-63), cutáneos difusa (ESD) y 4 limitada (ESL) en lapso de 9 meses. Once presentaron neumonía leve (84%), una neumonía grave con fallecimiento intrahospitalario (7.7%). La oximetría media al ambiente se mantuvo en SO2 90% (88-92%). Casi todos usaban inmunosupresores (84%) al momento de enfermar: micofenolato de mofetilo, metotrexato, prednisona en dosis bajas. Siete (53%) tenían enfermedad pulmonar intersticial (EPI) previa. Principalmente manifestaron disnea (67.5%), dolor torácico, tos, disgeusia y anosmia. Conclusiones: es posible que al momento del contagio con el virus SARS-CoV-2 los inmunosupresores permitieran una menor respuesta inflamatoria sistémica, evitando un peor pronóstico, incluso en quienes tienen enfermedad intersticial previa.

Background: The myocardial infarction-associated (MI) mortality is not only due cardiovascular complications, but intrahospital non-cardiovascular complications (IHnCVCs). The leuko-glycemic index (LGI) has been used as a prognostic marker for the development of cardiovascular complications in MI. We focused this study on identifying the cut-off point of LGI for the IHnCVCs development in patients with ST-segment elevation myocardial infarction (STEMI). Material and methods: In this single-center and crosssectional design, we included patients with STEMI. The biochemical analysis included glucose and leucocytes; with them we calculated the LGI. Receiver operating characteristic curve, univariate and bivariate analysis, and multivariate analysis for IHnCVCs development were performed. A p < 0.05 was considered statistically significant. Results: We included 1294 patients, 79.8% were men and 20.2% women. The main comorbidities were hypertension, diabetes mellitus and dyslipidemia. Six hundred forty-four (49.8%) patients presented IHNCVCs. The LGI > 1200 (AUC 0.817) predict the IHNCVCs development in STEMI patients. The variables that increased the IHNCVCs development were LGI > 1200, creatinine > 0.91 mg/dL, diabetes mellitus and age > 65 years. Hospital acquired pneumonia and cardiovascular complications increase the risk of death among STEMI patients. Conclusion: A LGI > 1200 increased, just over nine times, the risk of IHnCVC development in STEMI patients.
Introducción: la mortalidad asociada a infarto del miocardio (IM) no solo se debe a complicaciones cardiovasculares, sino tambien a complicaciones intrahospitalarias no cardiovasculares (CIHNC). El índice leuco-glucémico (ILG) se ha utilizado como un marcador pronóstico para el desarrollo de complicaciones cardiovasculares en el IM. Centramos este estudio en identificar el punto de corte de ILG para el desarrollo de CIHNC en pacientes con infarto de miocardio con elevación del segmento ST (IAMCEST). Material y métodos: en este diseño de un solo centro y transversal, incluimos pacientes con IAMCEST. El análisis bioquímico incluyó glucosa y leucocitos; se calculó ILG. Se realizaron análisis univariados y bivariados, curva ROC y análisis multivariado para el desarrollo de IAMCEST. Resultados: incluimos 1294 pacientes, 79.8% hombres y 20.2% mujeres. Las principales comorbilidades fueron: hipertensión arterial sistémica, diabetes mellitus y dislipidemia. Seiscientos cuarenta y cuatro pacientes (49.8%) presentaron CIHNC. El ILG > 1200 con área bajo la curva (AUC) 0.817 predice el desarrollo de CIHNC en pacientes con IAMCEST. Las variables que aumentaron el desarrollo de CIHNC fueron: ILG > 1200, creatinina > 0.91 mg/dL, diabetes mellitus y edad > 65 años. La neumonía intrahospitalaria y las complicaciones cardiovasculares aumentaron el riesgo de muerte entre los pacientes con IAMCEST. Conclusión: un LGI > 1200 aumentó más de nueve veces el riesgo de desarrollo de CIHNC en pacientes con IAMCEST.

BACKGROUND: Mexico is ranked second in obesity in adults worldwide and resident physicians are not exempt from this problem. Inadequate diet and physical inactivity are associated factors. Bioimpedance has greater precision than anthropometry. OBJECTIVE: To analyze the difference between degree of physical activity, caloric intake and body composition in Internal Medicine residents according to their degree of residence. MATERIAL AND METHODS: Cross-sectional study. Resident physicians of both sexes, from second, third and fourth degree of training were included; they were fasting. Vital signs were taken; a Rapid Assessment of Physical Activity (RAPA) questionnaire, anthropometry, a 24-hour reminder, and bioelectrical impedance analysis were administered. Descriptive statistics, Kruskal-Wallis and chi squared tests were used. RESULTS: 84 resident physicians were included, 48 were male. The median age was of 27 years (26-28). There was a prevalence of 46.4% of overweight and obesity, despite the hypocaloric diet in 89%. Bioelectrical impedance analysis showed that 72.6% of residents had elevated body fat, 71% sub-optimal degree of physical activity and 23.7% arterial hypertension. CONCLUSIONS: A high prevalence of overweight and obesity was found with differences in body composition and suboptimal level of physical activity. It is important to correct bad eating habits and improve physical activity to reduce risks in this population.
INTRODUCCIÓN: México es segundo lugar mundial en obesidad en adultos y los médicos residentes no están exentos de este problema. La dieta inadecuada y la inactividad física son factores asociados. La bioimpedancia tiene mayor precisión que la antropometría. OBJETIVO: analizar la diferencia entre grado de actividad física, ingesta calórica y composición corporal en residentes de Medicina Interna de acuerdo con su grado de residencia. MATERIAL Y MÉTODOS: estudio transversal. Se incluyeron médicos residentes de ambos sexos de segundo, tercero y cuarto grado, quienes participaron en ayuno. Se les tomaron signos vitales, se les otorgó el cuestionario Rapid Assesment of Physical Activity (RAPA), antropometría, recordatorio de 24 horas y medición de composición corporal por bioimpedancia. Se empleó estadística descriptiva, prueba de Kruskal-Wallis y chi cuadrada. RESULTADOS: se incluyeron 84 médicos residentes, 48 (57.14%) fueron del género masculino. La mediana de edad fue de 27 años (26-28). Se encontró una prevalencia de sobrepeso y obesidad de 46.4% a pesar de la dieta hipocalórica en el 89%. La medición por bioimpedancia indicó que 72.6% tuvo grasa corporal elevada, 71% grado de actividad física subóptimo y 23.7% hipertensión arterial. CONCLUSIONES: se encontró una alta prevalencia de sobrepeso y obesidad con diferencias en la composición corporal y el nivel subóptimo de actividad física. Es importante corregir los malos hábitos alimenticios y mejorar la actividad física para reducir riesgos en esta población.

BACKGROUND: The possibility that the blood group (BG) predisposes to SARS-CoV-2 infection is controversial. OBJECTIVE: To compare the prevalence of BG, anti-IgG SARS-CoV-2, and more frequent symptoms in convalescent health personnel vs controls prior to vaccination. MATERIAL AND METHODS: Analytical cross-sectional design of cases and controls, which included health personnel, from March to June 2020, confirmed with (polymerase chain reaction) PCR-SARS-CoV-2 and negative controls with PCR and anti-IgG-SARS-CoV-2. Participants were questioned concerning symptoms and BG was determined. It was used descriptive statistics and comparative analysis with chi squared, Fisher's exact test, Student's t, and Mann Whitney's U tests. RESULTS: Of 218 workers, 102 (46.8%) were confirmed cases for SARS-CoV-2 (convalescent) and 116 controls. The distribution of BG was similar between cases and controls, being BG-O + the most frequent (52.9%). The risk of becoming infected by SARS-CoV-2 for BG-O compared to BGNo-O showed a lower trend (odds ratio [OR] 0.725, 95% confidence interval [95% CI] 0.416-1.261, p = ns). The BG-A (28.4%) compared with BG-No-A (71.6%) showed a trend of increased risk in BG-A (OR 1.523, 95% CI 0.818-2.837, p = ns). The presence of SARS-CoV-2 IgG antibodies was 85% in the convalescent group. CONCLUSIONS: The prevalence of infected was proportionally higher for BG-A and lower for BG-O. About 15% did not develop SARS-CoV-2 antibodies after overcoming COVID-19 disease.
INTRODUCCIÓN: la posibilidad de que el grupo sanguíneo (GS) predisponga a infección por SARS-CoV-2 es controversial. OBJETIVO: comparar prevalencia de GS, anti-IgG SARSCoV-2 y síntomas más frecuentes, en personal de salud convaleciente frente a controles previo a la vacunación. MATERIAL Y MÉTODOS: diseño transversal analítico de casos y controles, que incluyó personal de salud, de marzo a junio de 2020, confirmados con reaccion en cadena de la polimerasa (PCR-SARS-CoV-2) y controles negativos con PCR y anti-IgG-SARS-COV-2. Se les interrogó sobre los síntomas y se determinó el GS. Se empleó estadística descriptiva y análisis comparativo con chi cuadrada o prueba exacta de Fisher y t de Student o U de Mann-Whitney. RESULTADOS: de 218 trabajadores, 102 (46.8%) fueron casos confirmados para SARS-CoV-2 (convalecientes) y 116 controles. La distribución de GS fue similar entre los casos y los controles y el GS-O+ fue el más frecuente (52.9%). El riesgo de infectarse de SARS-CoV-2 para el GS-O, comparado con GS-No-O mostró menor tendencia: razón de momios [RM] 0.725 (intervalo de confianza del 95% [IC 95%] 0.416-1.261; p = ns). El GS-A (28.4%) comparado con GSNo-A (71.6%) mostró tendencia de incremento del riesgo en GS-A, RM 1.523 (IC 95% 0.818-2.837, p = ns). La presencia de anticuerpos IgG de SARS-CoV-2 fue del 85% en el grupo de convalecientes. CONCLUSIONES: la prevalencia de infectados fue proporcionalmente mayor para GS-A y menor para GS-O. Alrededor de 15% no desarrollaron anticuerpos de SARS-CoV-2 después de recuperarse de COVID-19.

Material and methods: Analytical cross-sectional design of cases and controls, which included health personnel, from March to June 2020, confirmed with (polymerase chain reaction) PCR-SARS-CoV-2 and negative controls with PCR and anti-IgG-SARS-CoV-2. Participants were questioned concerning symptoms and BG was determined. It was used descriptive statistics and comparative analysis with chi squared, Fisher's exact test, Student's t, and Mann Whitney's U tests. Results: Of 218 workers, 102 (46.8%) were confirmed cases for SARS-CoV-2 (convalescent) and 116 controls. The distribution of BG was similar between cases and controls, being BG-O + the most frequent (52.9%). The risk of becoming infected by SARS-CoV-2 for BG-O compared to BG-No-O showed a lower trend (odds ratio [OR] 0.725, 95% confidence interval [95% CI] 0.416-1.261, p = ns). The BG-A (28.4%) compared with BG-No-A (71.6%) showed a trend of increased risk in BG-A (OR 1.523, 95% CI 0.818-2.837, p = ns). The presence of SARS-CoV-2 IgG antibodies was 85% in the convalescent group. Conclusions: The prevalence of infected was proportionally higher for BG-A and lower for BG-O. About 15% did not develop SARS-CoV-2 antibodies after overcoming COVID-19 disease.

Introducción: México es segundo lugar mundial en obesidad en adultos y los médicos residentes no están exentos de este problema. La dieta inadecuada y la inactividad física son factores asociados. La bioimpedancia tiene mayor precisión que la antropometría. Objetivo: analizar la diferencia entre grado de actividad física, ingesta calórica y composición corporal en residentes de Medicina Interna de acuerdo con su grado de residencia. Material y métodos: estudio transversal. Se incluyeron médicos residentes de ambos sexos de segundo, tercero y cuarto grado, quienes participaron en ayuno. Se les tomaron signos vitales, se les otorgó el cuestionario Rapid Assesment of Physical Activity (RAPA), antropometría, recordatorio de 24 horas y medición de composición corporal por bioimpedancia. Se empleó estadística descriptiva, prueba de Kruskal-Wallis y chi cuadrada. Resultados: se incluyeron 84 médicos residentes, 48 (57.14%) fueron del género masculino. La mediana de edad fue de 27 años (26-28). Se encontró una prevalencia de sobrepeso y obesidad de 46.4% a pesar de la dieta hipocalórica en el 89%. La medición por bioimpedancia indicó que 72.6% tuvo grasa corporal elevada, 71% grado de actividad física subóptimo y 23.7% hipertensión arterial. Conclusiones: se encontró una alta prevalencia de sobrepeso y obesidad con diferencias en la composición corporal y el nivel subóptimo de actividad física. Es importante corregir los malos hábitos alimenticios y mejorar la actividad física para reducir riesgos en esta población.
Background: Mexico is ranked second in obesity in adults worldwide and resident physicians are not exempt from this problem. Inadequate diet and physical inactivity are associated factors. Bioimpedance has greater precision than anthropometry. Objective: To analyze the difference between degree of physical activity, caloric intake and body composition in Internal Medicine residents according to their degree of residence. Material and methods: Cross-sectional study. Resident physicians of both sexes, from second, third and fourth degree of training were included; they were fasting. Vital signs were taken; a Rapid Assessment of Physical Activity (RAPA) questionnaire, anthropometry, a 24-hour reminder, and bioelectrical impedance analysis were administered. Descriptive statistics, Kruskal-Wallis and chi squared tests were used. Results: 84 resident physicians were included, 48 were male. The median age was of 27 years (26-28). There was a prevalence of 46.4% of overweight and obesity, despite the hypocaloric diet in 89%. Bioelectrical impedance analysis showed that 72.6% of residents had elevated body fat, 71% sub-optimal degree of physical activity and 23.7% arterial hypertension. Conclusions: A high prevalence of overweight and obesity was found with differences in body composition and suboptimal level of physical activity. It is important to correct bad eating habits and improve physical activity to reduce risks in this population.

BACKGROUND: Antiphospholipid syndrome (APS) is a systemic autoimmune disease, characterized by arterial or venous thrombosis and/or obstetric events in the presence of antiphospholipid antibodies (aPL). It is usually diagnosed in patients between the ages of 15 and 50 years, and there are 5 new cases per 100,000 people per year. It is reported a case of APS, which it is present in an older adult with an unusual clinical manifestation. CLINICAL CASE: Female patient without history of autoimmune diseases, at age 70 presented hemolytic anemia, Coombs direct positive, classified as autoimmune hemolytic anemia (AHAI) Coombs+, and severe thrombocytopenia. Other immunological, infectious, and lymphoid proliferative disorders and solid tumors were ruled out. Fisher-Evans syndrome (FES) was diagnosed with good response to treatment. Three months later, the patient presented deep venous thrombosis in the left pelvic limb, positive antiphospholipid antibodies (aPL) and positive aloantibodies were determined, establishing the diagnosis of primary APS and FES as its initial manifestation. Since then, the patient has been in treatment with acenocoumarol and prednisone without new recurrences of thrombosis, with persistence of moderate thrombocytopenia, without adding another clinical manifestation in 15 years of follow-up. CONCLUSION: The unusual presentation of this disease in older adults with comorbidities should not rule out the possibility of the development of a primary autoimmune disease, so it should be considered for diagnosis in this age group.
INTRODUCCIÓN: el síndrome antifosfolípido (SAF) es una enfermedad autoinmune sistémica, caracterizada por trombosis arterial o venosa, o eventos obstétricos en presencia de anticuerpos antifosfolípidos (aPL). Suele diagnosticarse entre los 15 y los 50 años, y hay cinco casos nuevos por cada 100 000 personas al año. Se reporta un caso de SAF que presenta una adulta mayor con manifestación clínica poco usual. CASO CLÍNICO: paciente mujer, sin antecedentes de enfermedades autoinmunes, que a los 70 años presentó anemia hemolítica y Coombs directo positivo, lo cual se catalogó como anemia hemolítica autoinmune (AHAI) Coombs+, y trombocitopenia severa. Se descartaron otros trastornos inmunológicos, infecciosos, linfoproliferativos y tumores sólidos, y se diagnosticó síndrome de Fisher-Evans (SFE) con buena respuesta al tratamiento. Tres meses después, la paciente presentó trombosis venosa profunda en miembro pélvico izquierdo. Se determinaron aPL positivos y aloanticuerpos positivos, y se estableció el diagnóstico de SAF primario y como su manifestación inicial el SFE. Desde entonces la paciente fue tratada con acenocumarina y prednisona sin recurrencias de trombosis, con persistencia de trombocitopenia moderada y sin nuevas manifestaciones clínicas en 15 años de seguimiento. CONCLUSIÓN: ante la presentación inusual de esta enfermedad en adultos mayores con comorbilidades no se debe descartar la posibilidad del desarrollo de una enfermedad autoinmune primaria, por lo cual se debe tener en cuenta para su diagnóstico en este grupo etario.
