L Allan James
Geomorphic systems often experience morphological changes that define a trajectory over decadal time periods. These trends can be halted by natural inhibitors such as vegetation, knickpoints, bed armor, or bank cohesion, or by anthropogenic inhibitors such as revetment, levees, or dams. Details about where and how channels and floodplains are stabilized are often poorly understood, which poses a risk that modern projects could unwittingly remove critical stabilizing elements (inhibitors) and unleash an episode of rapid change...

PURPOSE OF REVIEW: Ureteroscopic treatment of urolithiasis has become safer and more effective in the modern era. With a rise in the incidence of bilateral urolithiasis, management dilemma of staged single-side ureteroscopy versus bilateral simultaneous ureteroscopy (BS-URS) is often debatable. This review evaluates the current evidence base for bilateral simultaneous ureteroscopic approach in the modern era. RECENT FINDINGS: A systematic review was conducted from 1990 to June 2016 including all English language articles reporting on outcomes of BS-URS for urolithiasis...

The extraordinary responsiveness and large diversity of self-assembled structures of liquid crystals are well documented and they have been extensively used in devices like displays. For long, this application route strongly influenced academic research, which frequently focused on the performance of liquid crystals in display-like geometries, typically between flat, rigid substrates of glass or similar solids. Today a new trend is clearly visible, where liquid crystals confined within curved, often soft and flexible, interfaces are in focus...

Since the early 1990s, a series of studies underscored the overwhelming presence of positive eugenics in modern Argentina. These works emphasized the marginal role which discourse on eugenics took on violent methods for selection. In recent years, this point of view has shifted, emphasizing the conceptual viscosity of eugenics as well as the presence of negative eugenic discourses. This paper discusses these historiographic trends, and also dwells on the narratives that those perspectives articulated in relation to the question of sterilization and regulation of marriage of those who had tuberculosis in Buenos Aires during the first half of the twentieth century...

Observations over the 20th century evidence no long-term warming in the subpolar North Atlantic (SPG). This region even experienced a rapid cooling around 1970, raising a debate over its potential reoccurrence. Here we assess the risk of future abrupt SPG cooling in 40 climate models from the fifth Coupled Model Intercomparison Project (CMIP5). Contrary to the long-term SPG warming trend evidenced by most of the models, 17.5% of the models (7/40) project a rapid SPG cooling, consistent with a collapse of the local deep-ocean convection...

BACKGROUND: Improving access to reproductive health services and commodities is central to development. Efforts to assess progress on this front have been largely focused on national estimates, but such analyses can mask local disparities. We assessed progress in reproductive health services subnationally in India. METHODS: We developed a statistical model to generate estimates and projections of levels and trends in family planning indicators for subpopulations...

REVIEW
Paola Peluso, Victor Mamane, Emmanuel Aubert, Sergio Cossu
The term Atropisomerism defines a type of enantiomerism that arises from hindered rotation around an axis that makes two rotational isomers enantiomers. Atropisomeric compounds are present in nature, being important building blocks of many biologically active compounds. Atropisomers have been extensively studied in environmental and toxicological chemistry and, in particular, separating them has become a need in specific fields as organic synthesis and pharmaceutical research. High-performance liquid chromatography has been fruitfully applied in this context, and, despite HPLC separation on chiral stationary phase (CSP) is considered as mature technology nowadays, in the last years several advancements and applications contributed to study compounds where axial chirality is of utmost importance...

David Sands, Emil H Schemitsch
BACKGROUND: The current role of metal-on-metal (MoM) bearings in hip arthroplasty remains controversial. The low wear offered by MoM bearings compared to metal-on-polyethylene and the possibility of a lower risk of dislocation with larger head sizes, encouraged a trend towards the re-introduction of the MoM bearing couple. However, recent evidence has shown that not all designs of the MoM bearing have been successful. QUESTIONS/PURPOSES: The purpose of this paper is to provide an update on the use of MoM bearings and address the following issues: (1) the reintroduction of metal-on-metal bearings in total hip arthroplasty, (2) the failure of metal-on-metal bearings in stemmed total hip arthroplasty, (3) the role of metal-on-metal hip resurfacing in modern orthopaedics and (4) metal-on-metal hip resurfacing versus total hip arthroplasty...

This study explores the morphological differences between the enamel-dentine junction (EDJ) of maxillary and mandibular molars of Neanderthals (n = 150) and recent modern humans (n = 106), and between an earlier Neanderthal sample (consisting of Pre-Eemian and Eemian Neanderthals dating to before 115 ka) and a later Neanderthal sample (consisting of Post-Eemian Neanderthals dating to after 115 ka). The EDJ was visualised by segmenting microtomographic scans of each molar. A geometric morphometric methodology compared the positioning of the dentine horns, the shape of the marginal ridge between the dentine horns, and the shape of the cervix...

The prevention of childhood obesity is one of the greatest public health challenges of modern times. This has triggered the generation of a wealth of scientific evidence, culminating in a body of knowledge concerning the essential components of campaigns implemented in the school setting. In this regard, a growing trend towards the evaluation of research results in terms of effectiveness has become apparent, while the fieldwork itself very rarely comes under the spotlight. By considering the implementation process description of a multicomponent campaign designed to prevent childhood obesity in boys and girls in the 3(rd) year of primary education in Spain (9-10 years of age), the aim of this paper is to influence the elements of this process by considering important aspects pertaining to its implementation, such as its plausibility and feasibility in the particular context...

The term "luxury foodstuffs" refers to foods which are not consumed because of their nutritional value. Classic modern luxury foodstuffs are alcohol, caffeine-containing drinks, cocoa, sugar and tobacco. The following review article examines some of these modern luxury foodstuffs in detail, as well as their influence on glaucoma. Thus, small quantities of alcohol lower high intraocular pressure and have a positive influence on the blood circulation of the optic nerve. In addition, red wine polyphenols exert vasoprotective effects...

REVIEW
Simer Grewal, Murthy R Chamarthy, Sanjeeva P Kalva
Inferior vena cava (IVC) filter placement is a relatively low risk alternative for prophylaxis against pulmonary embolism in patients with pelvic or lower extremity deep venous thrombosis who are not suitable for anticoagulation. There is an increasing trend in the number of IVC filter implantation procedures performed every year. There are many device types in the market and in the early 2000s, the introduction of retrievable filters brought an additional subset of complications to consider. Modern filter designs have led to decreased morbidity and mortality, however, a thorough understanding of the limitations and complications of IVC filters is necessary to weight the risks and benefits of placing IVC filters...

The Lorenz energy cycle is widely used to investigate atmospheres and climates on planets. However, the long-term temporal variations of such an energy cycle have not yet been explored. Here we use three independent meteorological data sets from the modern satellite era, to examine the temporal characteristics of the Lorenz energy cycle of Earth's global atmosphere in response to climate change. The total mechanical energy of the global atmosphere basically remains constant with time, but the global-average eddy energies show significant positive trends...

Recent increases in family planning (FP) use have been reported among women of reproductive age in union (WRAU) in Senegal. However, trends have not been monitored among harder-to-reach groups (including adolescents, unmarried and rural poor women), key to understanding whether FP progress is equitable. We combined data from six Demographic and Health Surveys conducted in Senegal between 1992/93 and 2014. We examined FP trends over time among WRAU and subgroups, and trends in knowledge of FP and intention to use among women with unmet need for FP...
