Improving host health through microbial manipulation requires untangling factors that shape the microbiome. There is currently little understanding of how initial community structure may drive the microbiota trajectory across host development or influence bacterial therapy. Probiotic baths of surface symbionts, Pseudomonas fluorescens and Flavobacterium johnsoniae were administered to 240 tadpoles of the midwife toad, Alytes obstetricans in semi-natural outdoor mesocosms originating from geographically and genetically distinct populations in Switzerland...

The volume regulation graph is meant to relate the fundamental determinants of left ventricular (LV) function, namely end-systolic volume (ESV) and end-diastolic volume (EDV). This representation permits evaluation of the LV remodeling process, convenient stratification for clinically relevant covariates, as well as inscription of iso-stroke volume (SV) and iso-ejection fraction (EF) trajectories, the latter two as linear relationships. This retrospective study discusses LV volumetric parameters obtained from 155 patients (65 females) covering a wide spectrum of heart diseases...

Motor neurone disease (MND) is a progressive neurological disease causing muscle wasting, gradual paralysis and respiratory failure, with a life expectancy of 2-4 years. In order to better understand how MND is managed in the community, we conducted a qualitative study to explore the challenges healthcare professionals encounter when managing MND in primary healthcare. Based on data from 15 semi-structured interviews with primary healthcare professionals in Norway, we found that MND is viewed as a condition that requires exceptional effort and detailed planning...

REVIEW
Paola Tognini
During childhood, our brain is exposed to a variety of environmental inputs that can sculpt synaptic connections and neuronal circuits, with subsequent influence on behavior and learning processes. Critical periods of neurodevelopment are windows of opportunity in which the neuronal circuits are extremely plastic and can be easily subjected to remodeling in response to experience. However, the brain is also more susceptible to aberrant stimuli that might lead to altered developmental trajectories. Intriguingly, postnatal brain development is paralleled by the maturation of the gut microbiota: the ecosystem of symbionts populating our gastro-intestinal tract...

Supportive care and pharmacological treatment can improve the quality of life of people with end-stage chronic obstructive pulmonary disease (COPD) who cope on a daily basis with substantial physical, psychological, social and spiritual morbidity. Smoking cessation is the only intervention that reduces the rate of progression of COPD, but evidence-based drug treatments and non-pharmacological strategies can relieve symptoms and reduce the impact of exacerbations. People with severe COPD live with increasingly troublesome breathlessness and other symptoms such as fatigue, pain, sputum production and weight loss...

REVIEW

Although diseases of the heart are the leading cause of death in the USA, palliative care research has largely focused on populations of cancer patients. However, a diagnosis of heart failure differs substantially than that of cancer. They differ in terms of signs and symptoms, disease trajectories, treatment options, stigma, and prognosis. Additionally, the populations affected by these differing illnesses are also unique in a number of fundamental ways. Based on these differences, it is reasonable to hypothesize that palliative care patients with heart failure, and their families, have a distinct set of psychosocial needs...

EDITORIAL
Raman Kumar, Pritam Roy
Amid the global push for Universal Health Coverage (UHC), the agenda is being set for India's health care. In the absence of a constitutional mandate, a national policy and citizen-led political demand for UHC, there exist specific risks in rushing toward its implementation in India. As the debate of UHC continues, the health-care delivery system in India is at cross roads. UHC in India could take two different trajectories. The first one takes India toward becoming "Global Bazaar" of morbidity and ill health, founded on the pillars of a vibrant rapidly multiplying healthcare industry...

Epidemics caused by fungal plant pathogens pose a major threat to agro-ecosystems and impact global food security. High-throughput sequencing enabled major advances in understanding how pathogens cause disease on crops. Hundreds of fungal genomes are now available and analyzing these genomes highlighted the key role of effector genes in disease. Effectors are small secreted proteins that enhance infection by manipulating host metabolism. Fungal genomes carry 100s of putative effector genes, but the lack of homology among effector genes, even for closely related species, challenges evolutionary and functional analyses...

Patients with congenital heart disease (CHD) demonstrate multidomain cognitive delays. Cingulo-opercular and cerebellar brain networks are critical to language functions. This is a description of our initial experience aiming to identify an anatomic correlate for CHD patients with expressive language delays. Fetal CHD patients, prospectively enrolled, underwent serial fetal (1.5T), postnatal pre- and postoperative (3T) MRI. Non-CHD patients were enrolled retrospectively from the same epoch. Comparable fetal and neonatal T2 contrast was used for manual linear cross-sectional measurement...

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is associated with increased morbidity and mortality. The long-term association between AKI and end-stage renal disease (ESRD) in an Asian population is unknown. Given the high prevalence of diabetes and a younger age of presentation for cardiac surgery, it is important to track this progression of kidney disease. Therefore, we studied the long-term risk of ESRD and mortality in our Asian patients who developed AKI after cardiac surgery...

The Strength-Dexterity (SD) test measures the ability of the pulps of the thumb and index finger to compress a compliant and slender spring prone to buckling at low forces (<3N). We know that factors such as aging and neurodegenerative conditions bring deteriorating physiological changes (e.g., at the level of motor cortex, cerebellum, and basal ganglia), which lead to an overall loss of dexterous ability. However, little is known about how these changes reflect upon the dynamics of the underlying biological system...

Understanding brain volumetry is essential to understand neurodevelopment and disease. Historically, age-related changes have been studied in detail for specific age ranges (e.g., early childhood, teen, young adults, elderly, etc.) or more sparsely sampled for wider considerations of lifetime aging. Recent advancements in data sharing and robust processing have made available considerable quantities of brain images from normal, healthy volunteers. However, existing analysis approaches have had difficulty addressing (1) complex volumetric developments on the large cohort across the life time (e...

Designing highly selective human monoamine oxidase (hMAO) inhibitors is a challenging goal on the road to a more effective treatment of depression and anxiety (inhibition of hMAO-A isoform) as well as neurodegenerative diseases (inhibition of hMAO-B isoform). To uncover the molecular rationale of hMAOs selectivity, two recently prepared 2H-chromene-2-ones, namely compounds 1 and 2, were herein chosen as molecular probes being highly selective toward hMAO-A and hMAO-B, respectively. We performed molecular dynamics (MD) studies on four different complexes, cross-simulating one at a time the two hMAO-isoforms (dimer embedded in a lipid bilayer) with the two considered probes...
