The evidence behind the strong correlation between reactivation of tuberculosis (TB) and low body mass index (BMI) was reviewed. This strong association between TB and BMI occurred only with pulmonary TB and not extra-pulmonary TB, indicating that a low-BMI body build may in some way predispose to TB reactivation in the lungs. A possible explanation may be the congenital apical lung bullae that occur in 15% of the population and are likely to enlarge in young low-BMI males since biomechanical modeling of pleural stress has shown a massive 40x increase in apical pleural stress in low antero-posterior (AP) diameter chests associated with a low-BMI build...

Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), is a leading cause of morbidity and mortality worldwide. With the increased spread of multi drug-resistant TB (MDR-TB), there is a real urgency to develop new therapeutic strategies against M. tuberculosis infections. Traditionally, compounds are evaluated based on their antibacterial activity under in vitro growth conditions in broth; however, results are often misleading for intracellular pathogens like M. tuberculosis since in-broth phenotypic screening conditions are significantly different from the actual disease conditions within the human body...

Flow cytometry is an invaluable technology in the examination of blood, bone marrow, tissue and body fluids for the presence or absence of hematological disease. It is used in both diagnostic and follow-up testing, with an increasingly important role in the detection of very small residual disease populations (Minimal Residual Disease, MRD) However, flow cytometry immunophenotyping of leukemia and lymphoma is highly dependent on interpretation of results and with the increased complexity of 8-10 color instruments routinely used in clinical laboratories, knowledge of disease-defining populations is increasingly important as is recognizing normal and reactive patterns...

The optomotor response of animals is commonly used to measure their visual performance, e.g., rats of different genetically altered strains or various drug tests. With the presentation of stimuli using computer screens or projectors, the common idea focuses on measuring the eye movement or head and/or body movement to characterize changes of the head gaze. However, traditional methods rely on either the invasive fixation of animals, or the judgment of a human observer who reports the stimulus-tracking movements...

BACKGROUND: Adolescent bullying may be a key driver of interest in cosmetic surgery. This study examined the extent of such interest and whether any effect was sex-specific, and examined psychological functioning as a potential mechanism through which bullying involvement may lead to a wish for cosmetic surgery. METHODS: A two-stage design was used. In the first stage, 2782 adolescents (aged 11 to 16 years) were screened for bullying involvement using self-reports and peer nominations...

Commonly used tests for diagnosis of salt-sensitive hypertension (SSH) are complex and time-consuming, so new methods are required. Many studies have demonstrated roles for miRNAs in hypertension; however, the diagnostic value of miRNAs has yet to be determined for human SSH. In this study, we examined miRNA expression profiles by initial high-throughput miRNA sequencing of samples from patients with salt-sensitive and salt-resistant hypertension (SSH and SRH, respectively; n = 6, both groups), followed by validation by quantitative real-time polymerase chain reaction (qRT-PCR) in a larger cohort (n = 91)...

The objective was to evaluate the conicity index (C Index) as a predictor of changes in the lipid profile of adolescents and to establish its cutoff points. This was a cross-sectional study in 774 adolescents of both sexes (55% girls), 10 to 14 years of age. C Index was calculated according to the formula proposed by Valdez, considering body mass, height, and waist circumference (WC). Changes in the adolescents' lipid profile were defined according to one of the following conditions: elevated levels of total cholesterol, low-density lipoprotein (LDL), and triglycerides and low levels of high-density lipoprotein (HDL)...

REVIEW
Walter T McNicholas
Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome (OSA) are both highly prevalent, which implies that both disorders occurring together (overlap syndrome) is likely to be common based on chance association alone. However, different clinical COPD phenotypes influence the likelihood of co-existing OSA in that the increased lung volumes and low body mass index (BMI) associated with the predominant emphysema phenotype protects against OSA, whereas the higher likelihood of peripheral edema and increased BMI associated with the predominant chronic bronchitis phenotype promotes OSA...

BACKGROUND: Anaemia is one of the world's most prevalent child health problems. Its control in Africa and other developing nations has been hindered by uncertainty regarding its cause. Anaemia control has been particularly problematic in regions where the non-iron deficiency causes of anaemia, are projected to be substantial. The implementation of effective interventions to reduce the anaemia prevalence, requires improved documentation on iron status and other causes of anaemia for target populations...

The field of environmental toxicology developed as a result of growing concerns about anthropogenic influences on the environment and how to ameliorate ecological impact. Many governmental bodies are beginning to emphasize prevention rather than mitigation when addressing novel products, leading to more of a focus on identifying potential toxicity prior to release. With the exponential advances in their development and sale, novel metamaterials and biotechnology are set to dramatically outpace the capabilities of current testing strategies...

Patient brains with Parkinson's disease or Dementia with Lewy bodies show aggregation of alpha-synuclein in pre-cerebellar brainstem structures. Furthermore, patients exhibit resting tremor, unstable gait and impaired balance which may be associated with cerebellar dysfunction. Therefore, we screened the cerebella of 12 patients with alpha-synucleinopathies for neuropathological changes. Cerebellar nuclei and neighboring white matter displayed numerous aggregates, while lobules were mildly affected. Cerebellar aggregation pathology may suggest a prion-like spread originating from affected precerebellar structures and the high homogeneity between patients with Dementia with Lewy bodies and Parkinson's disease shows that both diseases likely belong to the same neuropathological spectrum...

The use of topological edge states for spintronic applications could be severely hampered by limited lifetimes due to intrinsic many-body interactions, in particular electron-phonon coupling. Previous works to determine the intrinsic coupling strength did not provide a coherent answer. Here, the electron-phonon interaction in the metallic surface state of 3D topological insulators is revised within a first principles framework. For the archetypical cases of Bi2Se3 and Bi2Te3, we find an overall weak coupling constant of less than 0...

To date, one of the most heavily cited assessments of caffeine safety in the peer-reviewed literature is that issued by Health Canada (Nawrot et al., 2003). Since then, >10,000 papers have been published related to caffeine, including hundreds of reviews on specific human health effects; however, to date, none have compared the wide range of topics evaluated by Nawrot et al. (2003). Thus, as an update to this foundational publication, we conducted a systematic review of data on potential adverse effects of caffeine published from 2001 to June 2015...

The overall goal of this pilot quality improvement (QI) intervention was to (1) assess the feasibility of making a WIC (Women, Infants, and Children) systems-level change that added measurement of maternal weight and discussion of maternal health habits into each postpartum maternal and offspring visit in rural clinics in Colorado and (2) assess the impacts of the intervention on maternal diet, physical activity, and weight status. A mixed-method evaluation approach was used involving the collection of quantitative data (HeartSmartMoms usage reports, manual WIC chart reviews [to calculate screening rates], pre-/postsurveys, and weight status [body mass index]) and qualitative data (focus groups and project team meeting minutes)...
