The prevalence and demographic associations of headache in the adult population of Peru: a national cross-sectional population-based study.

BACKGROUND: The Global Campaign against Headache is conducting a series of population-based studies to fill the large geographical gaps in knowledge of headache prevalence and attributable burden. One major region not until now included is South America. Here we present a study from Peru, a country of 32.4 million inhabitants located at the west coast of South America, notable for its high Andes mountains. METHODS: The study was conducted in accordance with the standardized methodology used by the Global Campaign. It was a cross-sectional survey using cluster randomised sampling in five regions to derive a nationally representative sample, visiting households unannounced, and interviewing one randomly selected adult member (aged 18-65 years) of each using the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire translated into South American Spanish. The neutral screening question ("Have you had headache in the last year?") was followed by diagnostic questions based on ICHD-3 and demographic enquiry. RESULTS: The study included 2,149 participants from 2,385 eligible households (participating proportion 90.1%): 1,065 males and 1,084 females, mean age 42.0 ± 13.7 years. The observed 1-year prevalence of all headache was 64.6% [95% CI: 62.5-66.6], with age-, gender- and habitation-adjusted prevalences of 22.8% [21.0-24.6] for migraine (definite + probable), 38.9% [36.8-41.0] for tension-type headache (TTH: also definite + probable), 1.2% [0.8-1.8] for probable medication-overuse headache (pMOH) and 2.7% [2.1-3.5] for other headache on ≥ 15 days/month (H15+). One-day prevalence of headache (reported headache yesterday) was 12.1%. Migraine was almost twice as prevalent among females (28.2%) as males (16.4%; aOR = 2.1; p < 0.001), and strongly associated with living at very high altitude (aOR = 2.5 for > 3,500 versus < 350 m). CONCLUSION: The Global Campaign's first population-based study in South America found headache disorders to be common in Peru, with prevalence estimates for both migraine and TTH substantially exceeding global estimates. H15 + was also common, but with fewer than one third of cases diagnosed as pMOH. The association between migraine and altitude was confirmed, and found to be strengthened at very high altitude. This association demands further study.

Epidemiología de la patología tumoral en el trasplante renal / Epidemiology of tumoral pathology in renal transplantation

Introducción: La patología tumoral (PT) implica una morbimortalidad no despreciable después del trasplante renal, siendo la inmunosupresión un factor de riesgo potencialmente responsable de su desarrollo. El objetivo de nuestro estudio es determinar la prevalencia de malignidad durante el trasplante y estudiar su posible asociación con el uso de anticuerpos antilinfocitarios, infección por citomegalovirus y el antecedente de rechazo agudo. Métodos: Se trata de un estudio de cohorte, retrospectivo, en 1034 receptores de trasplante renal en el que se revisaron los eventos tumorales acontecidos entre abril de 1981 y marzo de 2010. Se consignaron el uso de anticuerpos antilinfocitarios (AAL), infección por CMV y episodios de rechazo agudo (RA), relacionando estas variables con el desarrollo posterior de patología tumoral. Resultados: NO se detectó mayor frecuencia de PT maligna en aquellos que recibieron AAL (13,8% vs. 17,6%, p=0,094) p=0,094). No hubo mayor frecuencia de PT en pacientes con infección por CMV (16,3% vs. 15,2%, p=0,69). Por último, hubo mayor frecuencia de PT en aquellos con antecedentes de RA, si bien con significación limítrofe (19,5% vs. 14,3%, p=0,05). Conclusiones: La patología tumoral maligna se ve potencialmente favorecida por la inmunosupresión cada vez más potente y duradera. No hemos encontrado asociación entre la administración de AAL, infección y / o enfermedad por CMV; si bien esta se ve ligeramente incrementada en aquellos pacientes con el antecedente de RA.(AU)

Introduction: Tumoral pathology (TP) implies morbidity which is significant after the renal transplantation; Immunosuppression is a risk factor which is potentially responsible for tumoral development. The aim of our study is to determine the prevalence of malignancy during transplantation and to study its possible relation with the usage of antillymphocvte antibodies, cytomegalovirus infection and the history of acute rejection. Methods: It is a cohort study, retrospective, in 1014 receptors of Kidney transplantation in which tumoral events were revised between April 1981 and March 2010. The development of tumoral pathology in recipients was related with the usage of AAL, CMV infection and AR episodes. Results: a greater frequency of malign TP was no recorded in those who received AAL (13.8% vs. 17.6%, p=0.094). There was not greater frequency of TP in patients with infection due to CMV (16,3% vs, 15.2%, p=0.69). Finally, there was greater frequency of TP in those with antecedent of AR, though with bordering significance (19.5%, vs. 14.3% p=0.05). Conclusions: Malign tumoral pathology is potentially favored by immunosuppression increasingly powerful lasting. We have not found any relationship between AAL use, infection and/ or disease due to CMV, although this is slightly increased in those patients with AR history.(AU)

Evolución del estado nutricional en pacientes en hemodiálisis durante 4 años de seguimiento

La malnutrición proteíco calorica asi como la inflamación sistémica y metabólica son trastornos frecuentes entre los pacientes con insuficiencia renal crónica sometidos a tratamiento renal sustitutivo (Hemodiálisis), lo que contribuye a su morbilidad y mortalidad. En este trabajo se ha seguido a 90 pacientes de ambos sexos con insuficiencia renal crónica que fueron tratados con hemodiálisis periódicamente en nuestra unidad durante cuatro años. A todos los pacientes se le realizaron mediciones trimestrales de albúmina plasmática (Alb), colesterol total (CT), proteínas totales (PT) y mensuales de transferrina (Tr), y se les efectuaron mediciones antropométricas de peso, altura e índice de masa corporal calculado mediante la formula peso/talla², y agrupada según la clasificación de la OMS en IMC < 18,50 infrapeso, 18,50 a 24,99 normal, 1,25 a 29,99 sobrepeso y >30 del IMC s/OMS. El objetivo de este trabajo fue evaluar el estado nutricional de estos pacientes mediante la valoración de parámetros bioquímicos y parámetros antropométricos y determinar si estos pacientes sufren alteraciones que sugieran deterioro nutricional directamente relacionado con el tiempo en diálisis. Durante los 4 años todos los pacientes manifestaron un importante descenso de los parámetros bioquímicos, en cambio el IMC no presentó cambios significativos en relación a la desnutrición. Por lo tanto la desnutrición de los pacientes en diálisis es un hecho patente, el IMC no se corresponde con lo parámetros bioquímicos observados, por lo que el deterioro nutricional de estos pacientes se manifiesta principalmente mediante los parámetros bioquímicos estudiados.

Protein-calorie malnutrition as well as systemic inflammation and metabolic disorders are common among patients with chronic renal failure undergoing renal replacement therapy (hemodialysis), which contributes to their morbidity and mortality. This work has followed 90 patients of both sexes with chronic kidney disease who were treated with hemodialysis periodically in our unit for four years. All patients were performed quarterly measurements of plasma albumina (Alb), total cholesterol (TC), total protein (TP) and monthly transferrin (Tr), Anthropometric measurements of height and weight were taken on all patients by using a balance/stadiometer (Perperson 113481); weight was measured in kilograms and height in centimetres. BMI was calculated with this formula: weight/height2 and classified according to the WHO criteria: BMI.

[Evolution of nutritional status in hemodialysis patients during 4 years of follow]. / Evolución del estado nutricional en pacientes en hemodiálisis durante 4 años de seguimiento.

Protein-calorie malnutrition as well as systemic inflammation and metabolic disorders are common among patients with chronic renal failure undergoing renal replacement therapy (hemodialysis), which contributes to their morbidity and mortality. This work has followed 90 patients of both sexes with chronic kidney disease who were treated with hemodialysis periodically in our unit for four years. All patients were performed quarterly measurements of plasma albúmina (A1b), total cholesterol (TC), total protein (TP) and monthly transferrin (Tr), Anthropometric measurements of height and weight were taken on all patients by using a balance/stadiometer (Perperson 113481); weight was measured in kilograms and height in centimetres. BMI was calculated with this formula: weight/height2 and classified according to the WHO criteria: BMI < 18.50: Underweight; from 18.50 to 24.99: Normal range; from 25.00 to 29.99: Overweight; and BMI > or =30.00: Obese. The aim of this work was evaluate the nutritional status of these patients through the assessment of biochemical parameters and anthropometric parameters and determine if these patients suffer alterations suggesting nutritional deterioration directly related to the time on dialysis. During the 4 years all patients showed a significant decline of biochemical parameters, on the other hand the BMI did not significant changes in relation to malnutrition. Malnutrition in patients on dialysis is therefore evident, the BMI does not correspond with the biochemical parameters observed, so nutritional deterioration of these patients is mainly manifested by biochemical parameters studied.
