Article Synopsis
- - Horses transformed human mobility, but the timeline of their domestication and integration as transport is debated, with new genetic data being used to clarify this history.
- - Analysis of 475 ancient horse genomes indicates that modern domestic horses were shaped by human intervention around 2200 BCE, after a domestication bottleneck began around 2700 BCE, leading to a significant expansion across Eurasia.
- - Evidence also suggests that there was early horse husbandry in central Asia at Botai around 3500 BCE, prior to the establishment of contemporary horse bloodlines, challenging the notion of large herds being linked to migrations around 3000 BCE.
Article Synopsis
- The Maghreb region is crucial for studying how cattle genetics evolved after their domestication in the Fertile Crescent over 10,000 years ago.
- Researchers analyzed DNA from four Iron Age domestic cattle specimens in Althiburos, Tunisia, revealing two maternal lineages: R haplogroups and the more common African-T1 haplogroups.
- The findings suggest that there was hybridization between domesticated cattle and local aurochs, but there's also a possibility of independent domestication events occurring in North Africa.
Objective: To describe the census and contact investigation in a case of laryngeal tuberculosis.
Methods: Based on a patient with laryngeal tuberculosis and through interviews and ocular inspection, we established three circles of contacts. The tuberculin test was performed (positive ≥5 mm).
Objective: To investigate a waterborne outbreak in the population of València d'Àneu (Lleida, Spain).
Methods: A cohort study of consumption of mains water, bottled water and spring water was carried out. The sample was obtained by telephone contact with all private numbers in the municipality.
[Outbreak of whooping cough with a high attack rate in well-vaccinated children and adolescents].
Enferm Infecc Microbiol Clin
October 2011
Introduction: Whooping cough is a re-emerging disease. We describe the investigation of an outbreak of whooping cough and the measures of control adopted.
Methods: The event was reconstructed through a longitudinal study of incidence.
The aim of this study was to define the factors associated with the presence or risk of malnutrition in older adults (>65 years of age) attending health care centers in Lleida, Catalonia, using a cross-sectional study approach. Nutritional parameters assessed included the Mini Nutritional Assessment Scale, sociodemographic and psychosocial factors, functional and cognitive status, swallowing and oral problems, texture and route of administration of the diet, changes in dietary intake, and presence of digestive disorders. A total of 398 individuals (184 men) with an average age of 77 years were included in the assessment.

Design: A before-during-after comparative cross-sectional study.
Setting: Health areas of Lleida, High Pyrenees and Aran (Spain), from 2003-2006.
[Norovirus outbreaks in hospitals and nursing homes in Catalonia, Spain].
Rev Esp Salud Publica
March 2010
Background: The low infectious dose and multiple transmission routes favour the appearance of norovirus outbreaks. The objective of this study was to compare the incidence of norovirus outbreaks in hospitals and nursing homes in Catalonia.
Methods: A descriptive study of norovirus outbreaks between 15/10/2004 and 30/10/2005 was carried out.
Background And Objective: The aim of this study was to conduct an investigation into an outbreak of food-borne disease at a hotel, when epidemiological and microbiological results determined that the etiological agent was Norovirus and the source of infection was food handlers.
Patients And Method: We detected an outbreak of gastroenteritis in a group of 59 students and teachers from a secondary school who were staying at a hotel in Espot, Lleida (Spain). A historic cohort study was conducted into the consumption of water and food and clinical symptoms were also analyzed.
Background: Our goal was to investigate the epidemiological characteristics and etiology of an outbreak of food-borne disease caused by Norwalk-like viruses, genogroup II.
Patients And Method: We performed a historical cohort study on the consumption of 21 food items and clinical symptoms. We assessed RNA Norwalk-like viruses by RT- PCR in stool samples from 5 patients and 2 food-handlers.
