BACKGROUND: Most smokers do not use evidence-based smoking cessation treatment. Increasing utilization of these services is an important public health goal. Health care systems and insurers are well positioned to support this goal within their patient populations. We tested whether a brief, mail-based intervention increased utilization of tobacco cessation services among insured smokers. METHODS: Adult smokers were identified via automated health plan data and randomized to one of five treatment arms (n = 4767)...

EDITORIAL
Johnny Padulo, Andrea De Giorgio, Francesco Oliva, Antonio Frizziero, Nicola Maffulli
Writing a scientific article is not an easy task, but it is definitely a great satisfaction to be able to conclude and publish it. Indeed, each publication is a service we make to the entire scientific community and to the advancement of science even before our personal career. There is and there will not be a final book/article for writing a scientific paper. Therefore, some knowledge is a decisive factor to increase the chances of our work being accepted by a specialized scientific journal. The purpose of this editorial is to trace an ideal path, based on our personal experience, useful to properly structure a scientific article, from bibliographic research to cover letter...

Although the role of companion animals within the dynamic of domestic violence (DV) is increasingly recognized, the overlap of animal harm and insurance discrimination for victims/survivors of DV has not been considered. Prompted by a case study presented in a National Link Coalition LINK-Letter, this research note examines "Pet Insurance" policies available in Australia and whether nonaccidental injury caused by an intimate partner would be covered. We discuss the implications of exclusion criteria for victims/survivors of DV, shelters providing places for animals within a DV dynamic, and, more broadly, for cross- or mandatory-reporting (of animal harm) initiatives...

BACKGROUND: In many countries, access to general health and eye care is related to an individual's socioeconomic status (SES). We aimed to examine the prevalence of oculo-visual disorders in children in Istanbul Turkey, drawn from schools at SES extremes but geographically nearby. METHODS: Three school-based vision screenings (presenting distance visual acuity, cover test, eye assessment history, colour vision, gross stereopsis and non-cycloplegic autorefraction) were conducted on 81% of a potential 1014 primary-school children aged 4-10 years from two private (high SES) schools and a nearby government (low SES) school in central Istanbul...

BACKGROUND: Thank you letters to physicians and medical facilities are an untapped resource, providing an invaluable glimpse into what patients notice and appreciate in their care. OBJECTIVE: The aim of this study was to analyze such thank you letters as posted on the Web by medical institutions to find what patients and families consider to be good care. In an age of patient-centered care, it is pivotal to see what metrics patients and families apply when assessing their care and whether they grasp specific versus general qualities in their care...

Recognition of the phosphorylation sites in proteins is required for reconstruction of regulatory processes in living systems. This task is complicated because the phosphorylation motifs in amino acid sequences are considerably degenerated. To improve the prediction efficacy researchers often use additional descriptors, which should reflect physicochemical features of site-surrounding regions. We have evaluated the reasonability of this approach by applying molecular descriptors (MNA) for structural presentation of the peptide segments...

This cross-sectional study investigated California dentists’ knowledge and opinion of the interface between oral and overall health. A questionnaire and cover letter explaining the purpose of the study were mailed to 1,100 randomly selected California licensed general dentists. The survey measured dentists’ knowledge and opinions of the interface between oral and overall health as well as their recommendations for strengthening this interface. Dentists believed that there was minimal interface between oral and overall health care...

In this Letter, we present a tunable Y-branch hybrid master oscillator power amplifier (MOPA) with 5.5 W output power, emitting between 973.7 and 983.4 nm. The MO is a monolithic Y-branch distributed Bragg reflector (DBR) diode laser, which is collimated and coupled into a tapered amplifier using cylindrical microlenses in a compact 25  mm×25  mm conduction cooled laser package. The wavelength spacing between the two laser branches is 2.2 nm. Each branch can be electrically tuned by up to 7.5 nm of quasi-continuous wavelength tuning, which in combination covers up to 9...

Dynamic population inversion gratings induced in an active medium by counter-propagating optical fields may have a reverse effect on writing laser radiation via feedback they provide. In this Letter we report, to the best of our knowledge, on the first demonstration of an open-cavity fiber laser in which the distributed feedback is provided by a dynamic grating "written" in a Yb-doped active fiber, either by an external source or self-induced via a weak (∼0.1%) reflection from an angle-cleaved fiber end. It has been shown that meters-long dynamic grating is formed with a narrow bandwidth (<50  MHz) and a relatively high-reflection coefficient (>7%) securing single-frequency operation, but the subsequent hole-burning effects accompanied by new grating formation lead to the switching from one longitudinal mode to another...

Introduction Childhood psoriasis is a special situation that is a management challenge for the treating dermatologist. As is the situation with traditional systemic agents, which are commonly used in managing severe psoriasis in children, the biologics are being increasingly used in the recalcitrant disease despite limited data on long term safety. Areas covered - We performed an extensive literature search to collect evidence-based data on the use of biologics in pediatric psoriasis. The relevant literature published from 2000 to September 2017 was obtained from PubMed, using the MeSH words 'biologics', 'biologic response modifiers' or 'treatment of pediatric/childhood psoriasis'...

An electro-optic frequency comb enables frequency-agile comb-based spectroscopy without using sophisticated phase-locking electronics. Nevertheless, dense electro-optic frequency combs over broad spans have yet to be developed. In this Letter, we propose a straightforward and efficient method for electro-optic frequency comb generation with a small line spacing and a large span. This method is based on two-stage modulation: generating an 18 GHz line-spacing comb at the first stage and a 250 MHz line-spacing comb at the second stage...

This Letter explores the use of Ge-rich Si0.2Ge0.8 waveguides on graded Si1-xGex substrate for the demonstration of ultra-wideband photonic integrated circuits in the mid-infrared (mid-IR) wavelength range. We designed, fabricated, and characterized broadband Mach-Zehnder interferometers fully covering a range of 3 μm in the mid-IR band. The fabricated devices operate indistinctly in quasi-TE and quasi-TM polarizations, and have an extinction ratio higher than 10 dB over the entire operating wavelength range...

In this Letter, we study the motion and wake patterns of freely rising and falling cylinders in quiescent fluid. We show that the amplitude of oscillation and the overall system dynamics are intricately linked to two parameters: the particle's mass density relative to the fluid m^{*}≡ρ_{p}/ρ_{f} and its relative moment of inertia I^{*}≡I_{p}/I_{f}. This supersedes the current understanding that a critical mass density (m^{*}≈0.54) alone triggers the sudden onset of vigorous vibrations. Using over 144 combinations of m^{*} and I^{*}, we comprehensively map out the parameter space covering very heavy (m^{*}>10) to very buoyant (m^{*}<0...

S Bachmann, W De Roeck, M Fraas
The first proof of the quantum adiabatic theorem was given as early as 1928. Today, this theorem is increasingly applied in a many-body context, e.g., in quantum annealing and in studies of topological properties of matter. In this setup, the rate of variation ϵ of local terms is indeed small compared to the gap, but the rate of variation of the total, extensive Hamiltonian, is not. Therefore, applications to many-body systems are not covered by the proofs and arguments in the literature. In this Letter, we prove a version of the adiabatic theorem for gapped ground states of interacting quantum spin systems, under assumptions that remain valid in the thermodynamic limit...

OBJECTIVES: Electroconvulsive therapy (ECT) is an effective and a safe treatment for several severe psychiatric disorders across the age span. However, its use remains controversial and highly stigmatized especially among patients under 18 years. In this study, we examined current symptoms, attitudes, perception, and functioning of patients treated with ECT when they were less than 18 years old. METHODS: Participants had received ECT before age 18, between 1989 and 2015, at a tertiary medical center...

We studied the capability of a Hybrid functional neuroimaging technique to quantify human mental workload (MWL). We have used electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) as imaging modalities with 17 healthy subjects performing the letter n-back task, a standard experimental paradigm related to working memory (WM). The level of MWL was parametrically changed by variation of n from 0 to 3. Nineteen EEG channels were covering the whole-head and 19 fNIRS channels were located on the forehead to cover the most dominant brain region involved in WM...
