Temperature more info cooling shows direct positive association with the frequency of external aggression war to the Chinese dynasties mostly from the northern pastoral nomadic societies, and indirect positive

association with the frequency of internal war within the Chinese dynasties through drought and locust plagues. The collapses of the agricultural dynasties of the Han, Tang, Song and Ming are more closely associated with low temperature. Our study suggests that food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts owing to rebellions within the dynasties or/and southward aggressions from northern pastoral nomadic societies in ancient China.”
“The purpose of this randomised controlled trial was to examine the effect of regular exercise thenthereby ( three times/week) performed during the second and third trimester of pregnancy on the risk of prepartum maternal anaemia (haemoglobin <11 g/dl). 160 sedentary healthy women were randomly assigned either to a training or a control group (n = 80 each). Haematological variables were recorded at baseline (first trimester) and the beginning of the second and third trimesters. The frequency of participants with maternal anaemia was similar in the two groups over gestation (and consistently <10%). The course of haematological adaptations was normal and similar in both groups,

reflecting a steady fall in haemoglobin concentration over the second trimester due to haemodilution and a rise later in gestation due to haemoconcentration. In summary, regular exercise during the second half of pregnancy does not increase the risk of maternal anaemia nor does it alter haematological Anacetrapib variables.”
“Objective: To investigate sex differences in symptoms, structure of symptoms, disability and life satisfaction 3 years after mild traumatic brain injury. Secondary aims were to find risk factors for adverse outcome.\n\nDesign: Population-based cohort study.\n\nPatients: The cohort

comprised 137,000 inhabitants at risk in a defined population served by a single hospital in northern Sweden. Patients attending the emergency department following a mild traumatic brain injury in 2001 were included.\n\nMethods: Of 214 patients aged 18-64 years, 163 answered a questionnaire on symptoms, disability, and life-satisfaction 3 years post-injury. The instruments were analysed with descriptive statistics. A principal component analysis of the Rivermead Post-Concussion Symptoms Questionnaire was conducted. Risk factors were identified using logistic regression.\n\nResults: Post-concussion syndrome was found in 50% of the women and 30% of the men. Disability was found in 52% of the women and 37% of the men, and 57% of the women and 56% of the men were satisfied with their lives. For both genders, high frequency of symptoms was a risk factor for disability and low life satisfaction. Back pain was a risk factor for disability.
