[Association between body mass index and aggressiveness of papillary thyroid carcinoma]. / Asociación entre índice de masa corporal y agresividad del carcinoma papilar de tiroides.

The aim of the study was to evaluate the association of the body mass index (BMI) with the clinical-pathological characteristics and the recurrence of papillary thyroid carcinoma. The cohort consisted of 208 patients with papillary thyroid carcinoma diagnosed in 2003-2014, in Buenos Aires, Argentina. The patients were grouped according to the BMI as follows: BMI <18.5 kg/m2 (low weight); BMI ≥ 18.5 and < 25 kg/m2 (normal weight); BMI ≥ 25 and < 30 kg/m2 (overweight); BMI ≥ 30 kg/m2 (obesity). Two experienced pathologists reviewed and cross-checked all pathology specimens to confirm diagnosis, tumor characteristics and extent of the disease. All patients were followed every 6 months for 2 years, and annually thereafter. Recurrences were searched by using diagnostic imaging and histological confi rmation when necessary. Regression analysis was applied to defi ne associations of BMI with clinical, pathological, and prognosis features of the disease. A 5-point increase in BMI was significantly associated with tumor size (OR 1.21; 95% CI 1.1-1.5; p = 0.01) and greater extranodal extension in cervical metastases (OR 1.11; 95% CI 1.06-1.21; p = 0.03). The analysis of prognostic variables showed no association between increase in BMI and risk of recurrence (HR 1.11; 95% CI 0.91-1.22). In conclusion, we found that BMI relates directly with tumor size and extranodal extension, but not with recurrence.

El objetivo del estudio fue evaluar la asociación del índice de masa corporal (IMC) con las características clínico-patológicas y la recurrencia del carcinoma papilar de tiroides. La cohorte consistió en 208 pacientes con carcinoma papilar de tiroides diagnosticado en 2003-2014, en Buenos Aires, Argentina. El seguimiento fue semestral los primeros 2 años y luego anual. Los pacientes fueron agrupados según el IMC de la siguiente manera: IMC < 18.5 kg/m² (bajo peso); IMC ≥ 18.5 y < 25 kg/m² (peso normal); IMC ≥ 25 y < 30 kg/m² (sobrepeso); IMC ≥ 30 kg/m² (obesidad). Dos patólogos experimentados revisaron todas las muestras para determinar las características del tumor y la extensión de la enfermedad. La recurrencia tumoral fue evaluada mediante diagnóstico por imágenes y confirmación histológica. Se utilizó un análisis de regresión para identificar la asociación del IMC con las características clínico-patológicas del tumor y con la recurrencia. El aumento de 5 puntos en el IMC se asoció significativamente con mayor tamaño tumoral (OR 1.21; IC 95% 1.1-1.5; p = 0.01) y con mayor extensión extranodal de las metástasis cervicales (OR 1.11; IC95% 1.06-1.21; p = 0.03). No se observó asociación entre el aumento del IMC y el riesgo de recurrencia (HR 1.11; IC95% 0.91-1.22). En conclusión, se demostró una asociación directa del IMC con el tamaño tumoral y la extensión extranodal pero no con la recurrencia del tumor.

[Glycemic dysfunction prevalence post acute pancreatitis. A prospective study]. / Prevalencia de disfunción glucémica post pancreatitis aguda. Estudio prospectivo.

OBJECTIVE: To estimate the prevalence of altered metabolism of carbohydrates in patients with mild acute pancreatitis. METHODS: We included 85 patients diagnosed with pancreatitis. We used to evaluate prognosis Balthazar and Ranson criteria. All patients were interviewed and examined. Was performed routine laboratory and Oral glucose tolerance test (OGTT) We excluded patients with previous diagnosis of diabetes mellitus, alcoholic pancreatitis, severe hypertriglyceridemia and recurrent/ severe pancreatitis. RESULTS: 30 women and 27 men. After performing the OGTT were classified into three groups. Group 1 (n: 19): normal OGTT; Group 2 (n: 33): GAA, IHC, or both, and Group 3 (n = 5): with diabetes mellitus. Patients in group 3 had a higher average age (p = 0.02), and higher diastolic blood pressure (DBP) (p = 0.048). We observe a significant difference in fasting glucose values (p = 0.0001) and 120 minutes post-OGTT in all groups (p = 0.0001). HOMA was found higher (p = 0.031) in group 2. CONCLUSIONS: This study showing a link between mild acute pancreatitis and dysfunction of glucose metabolism, which found older patients, DBP and those with metabolic syndrome, had a higher prevalence of 65.66% of Pre diabetes and diabetes.
