Militarization and social development in the Third World

In this study we integrated the modernization and dependency theories of development to suggest the ways whereby militarization can affect development. We examined the effects of three components of militarization highlighted in these theories on the social development of ninety-two developing countries. Overall, our findings support the dependency theory's emphasis on the detrimental impact of international trade on disadvantaged nations. There is a significant negative correlation between arms import and social development. Arms export and indigenous spending are correlated with social development in the expected directions but their beta coefficients are not significant. The diverse ways these three aspects of militarization have been shown to affect social development help to explain some of the conflicting findings in the literature and point to the need to study these variables in their disaggregated form.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69141/2/10.1177_144078339503100105.pd

Accelerometer Measured Levels of Moderate-to-Vigorous Intensity Physical Activity and Sedentary Time in Children and Adolescents with Chronic Disease: a Systematic Review and Meta-Analysis

Context: Moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) are important for child and adolescent health. Objective: To examine habitual levels of accelerometer measured MVPA and ST in children and adolescents with chronic disease, and how these levels compare with healthy peers. Methods: Data sources: An extensive search was carried out in Medline, Cochrane library, EMBASE, SPORTDiscus and CINAHL from 2000–2017. Study selection: Studies with accelerometer-measured MVPA and/or ST (at least 3 days and 6 hours/day to provide estimates of habitual levels) in children 0–19 years of age with chronic diseases but without co-morbidities that would present major impediments to physical activity. In all cases patients were studied while well and clinically stable. Results: Out of 1592 records, 25 studies were eligible, in four chronic disease categories: cardiovascular disease (7 studies), respiratory disease (7 studies), diabetes (8 studies), and malignancy (3 studies). Patient MVPA was generally below the recommended 60 min/day and ST generally high regardless of the disease condition. Comparison with healthy controls suggested no marked differences in MVPA between controls and patients with cardiovascular disease (1 study, n = 42) and type 1 diabetes (5 studies, n = 400; SMD -0.70, 95% CI -1.89 to 0.48, p = 0.25). In patients with respiratory disease, MVPA was lower in patients than controls (4 studies, n = 470; SMD -0.39, 95% CI -0.80, 0.02, p = 0.06). Meta-analysis indicated significantly lower MVPA in patients with malignancies than in the controls (2 studies, n = 90; SMD -2.2, 95% CI -4.08 to -0.26, p = 0.03). Time spent sedentary was significantly higher in patients in 4/10 studies compared with healthy control groups, significantly lower in 1 study, while 5 studies showed no significant group difference. Conclusions: MVPA in children/adolescents with chronic disease appear to be well below guideline recommendations, although comparable with activity levels of their healthy peers except for children with malignancies. Tailored and disease appropriate intervention strategies may be needed to increase MVPA and reduce ST in children and adolescents with chronic disease

Data underlying the publication: "A mammalian commensal of the oropharyngeal cavity produces antibiotic and antiviral valinomycin in vivo"

Around weaning, piglets are susceptible to infection by bacterial pathogens, leading to increased morbidity and mortality. We identified isolates of Rothia nasisuis in the upper respiratory tract of weaned healthy piglets that produce valinomycin in vitro and in vivo via a giant multimodule non-ribosomal peptide synthase (NRPS) enzyme complex. Valinomycin is an antiviral and antibiotic ionophore that shuttles potassium ions across membranes and is capable of inflammasome activation and apoptosis in LPS-primed macrophages. R. nasisuis inhibited growth of Streptococcus and Rothia species inhabiting the same niche. To investigate the potential for the valinomycin-producing Rothia nasisuis strain to colonize new-born piglets we performed a colonization study in newborn litters of piglets. Briefly, the newborn piglets of 3 sows farrowing on the same day were randomized between the three sows to avoid genetic bias in the experiment. The sows were housed in separate maternity pens and the piglets marked so they could be identified during the study. 9 of the 12 piglets nursed by sows A and B (further referred to as litters A and B) were orally administered approximately 10exp9 CFU of valinomycin-producing R. nasisuis, using a syringe on d2, d19 and day 27 after birth. Three 3 piglets in litters A and B were not inoculated with R. nasisuis to see if they became colonized by horizontal transfer. As a control group all the piglets housed with the sow C (further referred to as litter C) were not inoculated with R. nasisuis
