[Epidemiology of premature deaths in Chile between 2001 and 2010].

Background: Years of potential life lost (YPLL) is a parameter that allows to analyze premature deaths.

Aim: To study the causes, differences by gender, geographic variations and the trend of premature deaths in the last decade in Chile.

Material And Methods: Using death databases published by the Ministry of Health, YPLL were calculated for the decade 2001-2010, using the method proposed by the Organization for Economic Cooperation and Development.

Fast detection of Piscirickettsia salmonis in Salmo salar serum through MALDI-TOF-MS profiling.

Piscirickettsia salmonis is a pathogenic bacteria known as the aetiological agent of the salmonid rickettsial syndrome and causes a high mortality in farmed salmonid fishes. Detection of P. salmonis in farmed fishes is based mainly on molecular biology and immunohistochemistry techniques.

Caries experience and use of dental services in rural and urban adults and older adults from central Chile.

Objective: To determine whether there is a relationship between the use of dental services and caries experience in adults and older adults from central Chile.

Materials And Methods: A sample of 453 adults, 35-44 years of age, and 438 older adults, 65-74 years of age, was interviewed and examined using World Health Organisation (WHO) methods. Sociodemographic variables were also registered.

Seasonal variation and resin composition in the Andean tree Austrocedrus chilensis.

Little is known about the changes in resin composition in South American gymnosperms associated with the different seasons of the year. The diterpene composition of 44 resin samples from seven Austrocedrus chilensis (Cupressaceae) trees, including male and female individuals, was investigated in three different seasons of the year (February, June and November). Twelve main diterpenes were isolated by chromatographic means and identified by gas chromatography-mass spectrometry and nuclear magnetic resonance (NMR).

Evaluation of the neuromuscular compartments in the peroneus longus muscle through electrical stimulation and accelerometry.

Background: Muscles are innervated exclusively by a nerve branch and possess definite actions. However, mammalian skeletal muscles, such as the trapezius, the medial gastrocnemius, and the peroneus longus, are compartmentalized. In the peroneus longus muscle, multiple motor points, which innervate individual neuromuscular compartments (NMC), the superior (S-NMC), anteroinferior (AI-NMC), and posteroinferior (PI-NMC), have been described.

[Prevalence of diabetes mellitus in the Seventh Region of Chile].

Background: The prevalence of diabetes mellitus in Latin America is not well known.

Aim: To study the real prevalence of diabetes mellitus (DM) and its associated risk factors in the VII region of Chile.

Material And Methods: A probabilistic sample of 1,325 subjects over the age of 20, stratified by age and differentiated by place of residence was studied.
