ABSTRACT Introduction: absenteeism constitutes a serious problem for the companies worldwide. Call centers are not the exception. Objectives: to determine causes of absenteeism for sickness absence and to identify sociodemographic and labour factors and direct cost in a call center in Medellín, 2016-2017. Material and Methods: a descriptive, transverse study. The study analysed 36.283 records of absenteeism that were registered in accordance to diagnoses (CIE 10). These records were re-classified according to medical criterion and it was calculated rates of absenteeism in accordance to NTC 3793. Results: 99.3% of absences were due to general illness. The average of absence is 4.28 +/-5.64 days per worker. Only 5% of absenteeism exceeded five days. The gastrointestinal diseases and of respiratory tract had the major days of absence. The repetitive absentee contributed a total 44,063 lost days. The chronic absentee generated a loss of 223 days per 100 workers.

RESUMEN Introducción: el absentismo laboral constituye un problema serio para las empresas a nivel mundial y los centros de teleoperadores no son la excepción. Objetivos: determinar las causas de absentismo laboral por incapacidad médica e identificar factores sociodemográficos, laborales y costos directos en un centro de teleoperadores de la ciudad de Medellín en el periodo 2016 - 2017. Material y Métodos: estudio descriptivo, transversal, donde se analizaron 36.283 registros de absentismo laboral que se registraron de acuerdo a diagnósticos (CIE-10), se reclasificaron según criterio médico. Se calcularon indicadores de absentismo laboral según NTC 3793. Resultados: el 99,3% de las ausencias se debió a enfermedad general. El promedio de ausencia es de 4,28 +/-5,64 días por trabajador. Solo el 5% de las incapacidades superaban los cinco días. Las enfermedades gastrointestinales y de vías respiratorias tuvieron los mayores días de ausencia. Los absentistas repetitivos aportaron en total 44.063 días perdidos. Los absentistas crónicos generaron una pérdida de 223 días por cada 100 trabajadores.

Triatominae are widely recognised for their role as vectors of Trypanosoma cruzi. One of the main biological characteristics of this subfamily is their obligate haematophagous condition. However, previous studies on Belminus herreri and Belminus ferroae suggested that cockroaches are their principal hosts in domiciles. Due to this peculiar behaviour, the aim of this study was to analyse several demographic and reproductive parameters of B. ferroae fed on three different hosts (mice, cockroaches and Rhodnius prolixus) and relate B. ferroae fitness to these alternative hosts. The cohorts were reared under constant conditions. The egg hatching rate was similar for cohorts fed on cockroaches (69.4%) and R. prolixus (63.8%), but was much lower for the cohort fed on mice (16%). The development time from the nymph to adult stage and the average age of first reproduction (α) presented lower values in the cohort fed on cockroaches, which is consistent with the higher population growth rate associated with this host. Demographic parameters [intrinsic rate of natural increase, finite rate of population growth, net reproductive rate and damping ratio] showed statistically significant differences between the cohorts. Analysis of the life history of B. ferroae revealed a higher fitness related to the cockroach. The implications of these results for the origin of the subfamily are discussed.
