#1
Peter Gelius, Alfred Rütten
As recently discussed in the public health literature, many questions concerning 'structural' approaches in health promotion seem to remain unanswered. We argue that, before attempting to provide answers, it is essential to clarify the underlying theoretical assumptions in order to arrive at the right questions one should ask. To this end, we introduce into the current debate an existing theoretical framework that helps conceptualize structural and individual aspects of health promotion interventions at different levels of action...

BACKGROUND: Vascularized lymph node (VLN) transfer for lymphedema treatment has shown promising results. Optimal donor and recipient sites remain a matter of debate. We describe the technique and outcomes of a laparoscopically harvested extended gastroepiploic VLN flap with two levels of inset. PATIENTS AND METHODS: Between 2014 and 2015, four-patients with upper limb breast cancer-related lymphedema and three-patients with lower limb pelvic cancer-related lymphedema who underwent VLN transfers were included...

Introduction: Vitamin D deficiency is common worldwide with adverse effects on skeletal health. In recent years, there has been great interest in non-classical actions of vitamin D. Basic research has uncovered actions in a range of non-skeletal tissues, and observational studies have identified inverse relationships with risk of a number of disease states including sarcopenia, obesity, the metabolic syndrome, cardiovascular disease, cancer and autoimmune diseases. Sources of data: PubMed, Medline and Cochrane Systematic Reviews...

Ostariophysi is a superorder of bony fishes including more than 10,300 species in 1,100 genera and 70 families. This superorder is traditionally divided into five major groups (orders): Gonorynchiformes (milkfishes and sandfishes), Cypriniformes (carps and minnows), Characiformes (tetras and their allies), Siluriformes (catfishes), and Gymnotiformes (electric knifefishes). Unambiguous resolution of the relationships among these lineages remains elusive, with previous molecular and morphological analyses failing to produce a consensus phylogeny...

Avilash Das, Emi Takahashi
The developmental relationships between gyral structures and white matter tracts have long been debated, but it is still difficult to discern whether they influence each other's development or are causally related. To explore this topic, this study used cats and ferrets as models for species that share similar gyral folding patterns and imaged with diffusion magnetic resonance imaging to compare white matter innervations in homologous gyri and other brain regions. Adult cat and ferret brains were analyzed via diffusion spectrum imaging tractography and homologous regions of interest were compared...

Background: The avalanche of commentaries on CRISPR-Cas9 technology, a bacterial immune system modified to recognize any short DNA sequence, cut it out, and insert a new one, has rekindled hopes for gene therapy and other applications and raised criticisms of engineering genes in future generations. Sources of data: This discussion draws on articles that emphasize ethics, identified partly through PubMed and Google, 2014-2016. Areas of agreement: CRISPR-Cas9 has taken the pace and prospects for genetic discovery and applications to a high level, stoking anticipation for somatic gene engineering to help patients...

The voice is an important part of human identity. The voice is susceptible to impact of hormons mainly sexual hormons. The larynx is one of secondary sex characacteristics. Disorders of voice pose serious obstacle to full social integration in male to female and female to male transsexuals. The causes of transsexuality are still a matter of considerable debate. Now it is considered that, big nucleus suprachiasmaticus in the hypothalamus may be a cause of transsexuality. The aim of phonosurgery in transsexual patients is to gain acceptable voice by the patients...

Transitive inference (TI) is a classic learning paradigm for which the relative contributions of experienced rewards and representation-based inference have been debated vigorously, particularly regarding the notion that animals are capable of logic and reasoning. Rhesus macaque subjects and human participants performed a TI task in which, prior to learning a 7-item list (ABCDEFG), a block of trials presented exclusively the pair FG. Contrary to the expectation of associative models, the high prior rate of reward for F did not disrupt subsequent learning of the entire list...

The conclusions on the association between cytotoxic T-lymphocyte antigen 4 (CTLA4) +49A/G gene polymorphism and acute rejection risk in renal transplantation are still debated. This meta-analysis was performed to update the association between CTLA4 +49A/G and acute rejection risk in renal transplantation. The association investigations were identified from PubMed and Cochrane Library, and eligible studies were included and synthesized using meta-analysis method. Fourteen reports were included into this meta-analysis for the association of CTLA4 A/G gene polymorphism and acute rejection risk in renal transplantation, consisting of 962 acute rejection patients and 2084 non-acute rejection controls...

Nicotinamide phosphoribosyltransferase (NAMPT) is an adipokine-enzyme, which was described as to play bioactivities both in the intracellular and in the extracellular environment. However, while the functions of intracellular NAMPT (iNAMPT) are well known, much less is known on extracellular NAMPT (eNAMPT), also called visfatin or pre-B cell colony-enhancing factor. iNAMPT catalyzes the rate-limiting step in the NAD+ biosynthesis pathway from nicotinamide. Its inhibition severely reduces intracellular NAD+ levels, achieving anti-inflammatory and anti-cancer effects...

STUDY QUESTION: Does thyroid autoimmunity (TAI) predict live birth rate in euthyroid women after one treatment cycle in IUI patients? SUMMARY ANSWER: TAI as such does not influence pregnancy outcome after IUI treatment. WHAT IS KNOWN ALREADY: The role of TAI on pregnancy outcome in the case of IVF/ICSI is largely debated in the literature. This is the first study to address this issue in the case of IUI. STUDY DESIGN, SIZE, DURATION: This was a retrospective cohort study...

Age of complementary foods introduction is associated with childhood anemia, but the ideal age for the introduction of complementary foods to infants is a continuing topic of debate. We examined the longitudinal association between complementary foods introduction age and risk of anemia in 18,446 children from the Jiaxing Birth Cohort, who had detailed complementary feeding records at 3 and 6 months of age and had hemoglobin concentrations measured at 4-6 years. Early introduction of complementary foods at 3-6 months of age was significantly associated with a higher risk of anemia (odds ratio = 1...

Post-treatment fertility emerges as an important issue in the early counseling of individuals with cancer, since survivors may have their quality of life affected by the occurrence of functional failure of the gonads because of antineoplastic therapies. In the context, oncofertility has been developed as an interdisciplinary field of study that combines expertise in reproductive medicine and oncology, to provide strategies aiming to maintain the possibility of future procreation. Today, we have many options and techniques available for the preservation of gametes in men and women...

OBJECTIVE: With the increased emphasis on personalized and individualized medicine, the American Association of Clinical Endocrinologists Adrenal Scientific Committee has developed a series of articles to update members on personalized medicine as it applies to adrenal diseases. METHODS: Synthesis of literature review, guidelines from professional societies, and personal experience. RESULTS: Since Conn described primary aldosteronism (PA) over 60 years ago, debate has raged about the prevalence of PA in the hypertensive population, the wisdom of broadly screening for PA, and prudent approach to the evaluation and management of these patients...

Neal L Benowitz, Joseph B Fraiman
Cardiovascular safety is an important consideration in the debate on the benefits versus the risks of electronic cigarette (EC) use. EC emissions that might have adverse effects on cardiovascular health include nicotine, oxidants, aldehydes, particulates, and flavourants. To date, most of the cardiovascular effects of ECs demonstrated in humans are consistent with the known effects of nicotine. Pharmacological and toxicological studies support the biological plausibility that nicotine contributes to acute cardiovascular events and accelerated atherogenesis...

After years of unprecedented growth in development assistance for health (DAH), the DAH system is challenged on several fronts: by the economic downturn and stagnation of DAH, by the epidemiological transition and increase in non-communicable diseases and by the economic transition and rise of the middle-income countries. Central to any potent response is a fair and effective allocation of DAH across countries. A myriad of criteria has been proposed or is currently used, but there have been no comprehensive assessment of their distributional implications...

After a 'golden age' of extraordinary growth in the level of development assistance for health (DAH) since 1990, funding seems to have reached a plateau. With the launch of the Sustainable Development Goals, debate has intensified regarding what international financing for health should look like in the post-2015 era. In this review paper, we offer a systematic overview of problems and proposals for change. Major critiques of the current DAH system include: that the total volume of financing is inadequate; financial flows are volatile and uncertain; DAH may not result in additional resources for health; too small a proportion of DAH is transferred to recipient countries; inappropriate priority setting; inadequate coordination; weak mechanisms for accountability; and disagreement on the rationale for DAH...

After years of unprecedented growth in development assistance for health (DAH), the system is challenged on several fronts: by the economic downturn and stagnation of DAH, by the epidemiological transition and increase in non-communicable diseases, and by the economic transition and rise of the middle-income countries. This raises questions about which countries should receive DAH and how much, and, fundamentally, what criteria that promote fair and effective allocation. Yet, no broad comparative assessment exists of the criteria used today...

The effectiveness of water flooding oil recovery depends to an important extent on the competitive wetting of oil and water on the solid rock matrix. Here, we use macroscopic contact angle goniometry in highly idealized model systems to evaluate how brine salinity affects the balance of wetting forces and to infer the microscopic origin of the resulting contact angle alteration. We focus in particular on two competing mechanisms debated in the literature, namely double layer expansion and divalent cation bridging...

Transition metal oxides are complex electronic systems that exhibit a multitude of collective phenomena. Two archetypal examples are VO2 and NdNiO3 , which undergo a metal-insulator phase transition (MIT), the origin of which is still under debate. Here this study reports the discovery of a memory effect in both systems, manifested through an increase of resistance at a specific temperature, which is set by reversing the temperature ramp from heating to cooling during the MIT. The characteristics of this ramp-reversal memory effect do not coincide with any previously reported history or memory effects in manganites, electron-glass or magnetic systems...
