Pediatric rare lung disease (PRLD) is a term that refers to a heterogeneous group of rare disorders in children. In recent years, this field has experienced significant progress marked by scientific discoveries, multicenter and interdisciplinary collaborations, and efforts of patient advocates. Although genetic mechanisms underlie many PRLDs, pathogenesis remains uncertain for many of these disorders. Furthermore, epidemiology and natural history are insufficiently defined, and therapies are limited. To develop strategies to accelerate scientific advancement for PRLD research, the NHLBI of the National Institutes of Health convened a strategic planning workshop on September 3 and 4, 2015...

Missing data is a common issue in community health and epidemiological studies. Direct removal of samples with missing data can lead to reduced sample size and information bias, which deteriorates the significance of the results. While data imputation methods are available to deal with missing data, they are limited in performance and could introduce noises into the dataset. Instead of data imputation, a novel method based on additive least square support vector machine (LS-SVM) is proposed in this paper for predictive modeling when the input features of the model contain missing data...

BACKGROUND: For years, many scholars dismissed the possibility that terrorists - including suicide attackers - could be mentally ill or primarily suicidal. However, that view is gradually changing. AIM: Researchers continue to face significant challenges when attempting to detect mental health problems and suicidal motives among terrorists and mass shooters, because many offenders cannot easily be psychologically assessed. This article offers several specific recommendations for how researchers can better understand offenders' mental state by studying their life histories and behaviour...

We assess how well differences in ethnoracial background may predict timing of menopause among females in the USA and whether or not inflammatory biomarker levels appear to mediate these overall associations. We use data from the National Social Life, Health, and Aging Project (NSHAP) to model apparent net effects from race on menopausal onset, as well as possible mediating influences from the inflammatory biomarker C-reactive protein (CRP). Using continuous time event history analysis, we assess and frame overall relationships between race and menopausal age...

BACKGROUND: Total Knee Arthroplasty (TKA) is a common surgical treatment for severe knee Osteoarthritis (OA), which generally improves pain, physical function, quality of life and possibly fall risk. Fall risk increases for older adults with severe knee OA; however it has not been studied extensively whether this parameter is improved after TKA. OBJECTIVE: To investigate: a) the history and frequency of falls, including mechanism or causes of falls, injuries sustained from falls reported, activity during falling and location of falls and, b) the factors affecting falls, a year after TKA in elderly patients with severe knee OA...

BACKGROUND: Emergency department attendances with chest pain requiring assessment for acute coronary syndrome (ACS) are a major global health issue. Standard assessment includes history, examination, electrocardiogram (ECG) and serial troponin testing. Computerised tomography coronary angiography (CTCA) enables additional anatomical assessment of patients for coronary artery disease (CAD) but has only been studied in very low-risk patients. This trial aims to investigate the effect of early CTCA upon interventions, event rates and health care costs in patients with suspected/confirmed ACS who are at intermediate risk...

BACKGROUND: As global climate change transforms average temperature and rainfall, species distributions may meet, increasing the potential for hybridization and altering individual fitness and population growth. Altered rainfall specifically may shift the strength and direction of selection, also manipulating population trajectories. Here, we investigated the role of interspecific hybridization and selection imposed by rainfall on the evolution of weedy life-history in non-hybrid (Raphanus raphanistrum) and hybrid (R...

Mental disorders rank first amongst all causes for disability pensions and second in the field of medical rehabilitation. Especially alarming is the significantly lower age of entry of the mentally ill disability pensioners, compared to those with other indications. Mentally ill people often look back at a long history of diseases before getting in contact with the German pension insurance. In this regard the German pension insurance, which is obligated to effectively support people in order to keep them in working life until reaching the regular retirement age, is facing a big challenge, which stands right next to further demands, due to the demographic change, the increase of chronic diseases, multimorbidity, retirement age of 67 and changes in the working environment...

INTRODUCTION: Anorexia Nervosa affects up to 1% of the population and can present with binge/purge episodes. A paucity of literature exists regarding small bowel and colonic ischaemia relating to this common condition. We report our own experience and management of a patient with anorexia nervosa binge/purge subtype with small bowel and colon ischaemia and review existing cases in the literature. PRESENTATION OF CASE: A 32year old female self-presented to the emergency department complaining of abdominal pain, abdominal distension and vomiting on a background history of binge/purge subtype eating disorder, following consumption of a large amount of carbohydrates...

OBJECTIVE: Maternal age at birth of last child has been associated with maternal longevity. The aim of this study was to determine whether older women with a history of late maternal age at last childbirth had a longer leukocyte telomere length than those with maternal age at last childbirth of 29 years or less. METHODS: A nested case control study was conducted using data from the Long Life Family Study. Three hundred eighty-seven women who gave birth to at least one child and lived to the top fifth percentile of their birth cohort, or died before the top fifth percentile of their birth cohort died, but were at least 70 years old, were studied...

The objective of this study was to define which stroke-related factors constitute independent variables in the incidence of intestinal constipation (IC) of chronic patients admitted to a hospital rehabilitation program. All patients consecutively admitted for rehabilitation were recruited for the study. In the Poisson multiple regression analysis using a hierarchical model, sociodemographic variables, comorbidities, medication, previous history of constipation, life habits, and stroke-related variables were considered for defining factors associated with IC...

Migration is an important life-history event in a wide range of taxa, yet many migrations are influenced by anthropogenic change. Although migration dynamics are extensively studied, the potential effects of environmental contaminants on migratory physiology are poorly understood. In this study we show that an anxiolytic drug in water can promote downward migratory behaviour of Atlantic salmon (Salmo salar) in both laboratory setting and in a natural river tributary. Exposing salmon smolt to a dilute concentration of a GABAA receptor agonist (oxazepam) increased migration intensity compared with untreated smolt...

The relative importance of interactions between mitochondrial and nuclear genes on adaptation has gained increased attention (see Wolff et al., 2014), although experimental systems to make direct tests of its importance are scarce. Mitonuclear epistasis is when nuclear and mitochondrial genes interact, often at the protein level, and variation in these interactions may result in phenotypic differences (Paliwal et al., 2014). These interactions are often found in the mitochondria where the energy-generating electron transport chain (ETC) is located, and consists of both nuclear and mitochondrial proteins...

The Major Histocompatibility Complex (MHC) plays a key role in pathogen recognition as a part of vertebrate adaptive immune system. The great diversity of MHC genes in natural populations is maintained by different forms of balancing selection and its strength should correlate with the diversity of pathogens to which a population is exposed and the rate of exposure. Despite this prediction, little is known about how the life-history characteristics affect selection at the MHC. Here, we examined whether the strength of balancing selection on MHC class II genes in birds (as measured with nonsynonymous nucleotide substitutions, dN) was related to their social or migratory behaviour, two life-history characteristics correlated with pathogen exposure...

This article revisits the development of the protoplasm concept as it originally arose from critiques of the cell theory, and examines how the term "protoplasm" transformed from a botanical term of art in the 1840s to the so-called "living substance" and "the physical basis of life" two decades later. I show that there were two major shifts in biological materialism that needed to occur before protoplasm theory could be elevated to have equal status with cell theory in the nineteenth century. First, I argue that biologists had to accept that life could inhere in matter alone, regardless of form...

The effective management of invasive species requires detailed understanding of the invader's life history. This information is essential for modeling population growth and predicting rates of expansion, quantifying ecological impacts and assessing the efficacy of removal and control strategies. Indo-Pacific lionfish (Pterois volitans/miles) have rapidly invaded the western Atlantic, Gulf of Mexico and Caribbean Sea with documented negative impacts on native ecosystems. To better understand the life history of this species, we developed and validated a length-based, age-structured model to investigate age, growth and population structure in northeast Florida...

Osteoporosis (OP) is a silent disease unless a fracture occurs; it is a major health problem, mainly due to fragility fractures, that occur at vertebral and peripheral sites. Vertebral fractures (VF) are probably the most common fragility fractures, but they go often unrecognized. The main clinical symptoms of VF are acute and chronic back pain, spinal deformity, reduced mobility and impaired quality of life. They are frequently associated with other fragility fractures. We examined 478 patients at our outpatient clinic, who were referred for fragility fracture occurrence...

Background: Due to the lack of objective measures for assessing tinnitus, its clinical evaluation largely relies on the use of questionnaires and psychoacoustic tests. A global assessment of tinnitus burden would largely benefit from holistic approaches that not only incorporate measures of tinnitus but also take into account associated fears, emotional aspects (stress, anxiety, and depression), and quality of life. In Sweden, only a few instruments are available for assessing tinnitus, and the existing tools lack validation...
