Geographic trends of tobacco-related cancers in Cyprus.

Background: Causal relationships have been previously established between smoking and various cancers. In Cyprus, 39 % of men and 14 % of women reported daily smoking in 2008. The objective of this study was to compare the incidence of tobacco-related cancers to all other cancers by district and rural-urban classification to understand the impact of tobacco in Cyprus.

Neurochemical changes in the pericalcarine cortex in congenital blindness attributable to bilateral anophthalmia.

Congenital blindness leads to large-scale functional and structural reorganization in the occipital cortex, but relatively little is known about the neurochemical changes underlying this cross-modal plasticity. To investigate the effect of complete and early visual deafferentation on the concentration of metabolites in the pericalcarine cortex, (1)H magnetic resonance spectroscopy was performed in 14 sighted subjects and 5 subjects with bilateral anophthalmia, a condition in which both eyes fail to develop. In the pericalcarine cortex, where primary visual cortex is normally located, the proportion of gray matter was significantly greater, and levels of choline, glutamate, glutamine, myo-inositol, and total creatine were elevated in anophthalmic relative to sighted subjects.

An organizational readiness intervention and randomized controlled trial to test strategies for implementing substance use disorder treatment into primary care: SUMMIT study protocol.

Background: Millions of people who need treatment for substance use disorders (SUD) do not receive it. Evidence-based practices for treating SUD exist, and some are appropriate for delivery outside of specialty care settings. Primary care is an opportune setting in which to deliver SUD treatment because many individuals see their primary care providers at least once a year.

The importance of workforce surveillance, research evidence and political advocacy in the context of international migration of dentists.

The international migration of dentists is an issue of pressing significance that poses several complex policy challenges. Policy-making is mainly constrained by the lack of workforce surveillance, research evidence and political advocacy - all three are required to work together, yet with different purposes. We first discuss the inconsistencies in migrant dentist surveillance in major country-level governmental systems (immigration departments, dentist registration authorities and workforce agencies).

Decisions about prophylactic gynecologic surgery: a qualitative study of the experience of female Lynch syndrome mutation carriers.

Background: Women who carry a mutation for Lynch syndrome face complex decisions regarding strategies for managing their increased cancer risks. At present, there is limited understanding of the factors influencing women's prophylactic surgery decisions.

Methods: As part of an exploratory pilot project, semi-structured interviews were conducted with 10 women who were Lynch syndrome mutation carriers and had made prophylactic surgery decisions.

Neural activation in speech production and reading aloud in native and non-native languages.

We used fMRI to investigate neural activation in reading aloud in bilinguals differing in age of acquisition. Three groups were compared: French-English bilinguals who acquired two languages from birth (simultaneous), French-English bilinguals who learned their L2 after the age of 5 years (sequential), and English-speaking monolinguals. While the bilingual groups contrasted in age of acquisition, they were matched for language proficiency, although sequential bilinguals produced speech with a less native-like accent in their L2 than in their L1.

Physical Models for Charge Transfer at Single Crystal Oxide Semiconductor Surfaces as Revealed by the Doping Density Dependence of the Collection Efficiency of Dye Sensitized Photocurrents.

The doping density dependence of photocurrents has been experimentally measured at single crystal rutile TiO2 electrodes sensitized with the N3 chromophore and a trimethine dye. As the doping density of the electrodes was varied from 10(15) to 10(20) cm(-3), three different regimes of behavior were observed for the magnitude and shape of the dye sensitized current-voltage curves. Low-doped crystals produced current-voltage curves with a slow rise of photocurrent with potential.

The Affordable Care Act: an opportunity for improving care for substance use disorders?

The Patient Protection and Affordable Care Act (ACA) will greatly increase coverage for treatment of substance use disorders. To realize the benefits of this opportunity, it is critical to develop reliable, valid, and feasible measures of quality to ensure that treatment is accessible and of high quality. The authors review the availability of current quality measures for substance use disorder treatment and conclude there is a pressing need for development, validation, and use of quality measures.

Creation of gastric conduit free-graft with intraoperative perfusion imaging during pancreaticoduodenectomy in a patient post esophagectomy.

As surgery becomes more successful for complicated malignancies, patients survive longer and can unfortunately develop subsequent malignancies. Surgical resection in these settings can be treacherous and manipulations of the patient's anatomy need to be closely considered before embarking on major operations. We report a case of a patient who survived esophageal resection for locally advanced esophageal cancer only to develop a new pancreatic head malignancy.

Characteristics and practice profiles of migrant dentist groups in Australia: implications for dental workforce policy and planning.

Introduction: Migrants comprise a growing proportion of the dental workforce in Australia. To date, research on migrant dentists is limited, raising policy questions regarding the motivations for migration, demographic profiles and work patterns. The purpose of this paper was to present findings from the first national survey of migrant dentists in Australia.

Subcortical functional reorganization due to early blindness.

Lack of visual input early in life results in occipital cortical responses to auditory and tactile stimuli. However, it remains unclear whether cross-modal plasticity also occurs in subcortical pathways. With the use of functional magnetic resonance imaging, auditory responses were compared across individuals with congenital anophthalmia (absence of eyes), those with early onset (in the first few years of life) blindness, and normally sighted individuals.

The neurological underpinnings of cluttering: Some initial findings.

Background: Cluttering is a fluency disorder characterised by overly rapid or jerky speech patterns that compromise intelligibility. The neural correlates of cluttering are unknown but theoretical accounts implicate the basal ganglia and medial prefrontal cortex. Dysfunction in these brain areas would be consistent with difficulties in selection and control of speech motor programs that are characteristic of speech disfluencies in cluttering.

HPV awareness, knowledge and attitudes among older African-American women.

Objective: To assess correlates of human papillomavirus (HPV) awareness, knowledge, and attitudes among older, church-going African-American women.

Methods: Participants (N = 759), aged 40-80, answered survey questions about HPV awareness, knowledge, and attitudes toward vaccination of adolescent daughters. Associations between participant characteristics and HPV items were assessed using chi-square tests and logistic regression analyses.

Supportive housing: an evidence-based intervention for reducing relapse among low income adults in addiction recovery.

Within the ranks of the homeless are individuals coping with substance addiction and/or chronic physical or mental disability. Their special needs often pose significant barriers to successfully re-integrate into society. For these individuals, simply securing a roof overhead may not be an adequate solution.

pH-responsive, lysine-based hydrogels for the oral delivery of a wide size range of molecules.

Hydrogels synthesized from poly(l-lysine isophthalamide) (PLP) crosslinked with l-lysine methyl ester were investigated as drug delivery systems for a wide size range of molecules (0.3-2000kDa). PLP is an anionic, pseudo-peptidic polymer that is an ideal hydrogel backbone due to its pH-responsiveness and amphiphilicity.

Grazing dairy cows had decreased interferon-γ, tumor necrosis factor, and interleukin-17, and increased expression of interleukin-10 during the first week after calving.

Peripartum, and especially during the transition period, dairy cows undergo dramatic physiological changes. These coincide with an increased risk of disease during the first 2 wk after calving and have been linked to dairy cows failing to achieve production as well as reproductive targets. Previous evidence suggests that these physiological changes affect the immune system and that transition dairy cows experience some form of reduced immunocompetence.

Tolerability of denosumab in metastatic solid tumor patients with renal insufficiency.

Purpose: Denosumab is approved for the prevention of skeletal-related events (SREs) in metastatic solid tumor patients with bone metastases. Limited data regarding the safety of denosumab in patients with severe renal insufficiency suggests increased rates of hypocalcemia compared to patients with normal renal function. The purpose of this study was to assess the rates of hypocalcemia and hypophosphatemia in cancer patients with severe renal impairment.

Comparative analysis of the transcriptome across distant species.

The transcriptome is the readout of the genome. Identifying common features in it across distant species can reveal fundamental principles. To this end, the ENCODE and modENCODE consortia have generated large amounts of matched RNA-sequencing data for human, worm and fly.

Discrimination of speech and non-speech sounds following theta-burst stimulation of the motor cortex.

Perceiving speech engages parts of the motor system involved in speech production. The role of the motor cortex in speech perception has been demonstrated using low-frequency repetitive transcranial magnetic stimulation (rTMS) to suppress motor excitability in the lip representation and disrupt discrimination of lip-articulated speech sounds (Möttönen and Watkins, 2009). Another form of rTMS, continuous theta-burst stimulation (cTBS), can produce longer-lasting disruptive effects following a brief train of stimulation.

Overseas-qualified dentists' experiences and perceptions of the Australian Dental Council assessment and examination process: the importance of support structures.

Objective: The Australian Dental Council is responsible for the assessment of overseas-qualified dentists seeking to practice dentistry in Australia. The aim of this paper is to reflect on the Council's assessment and examination process through the experiences and perceptions of overseas-qualified dentists in Australia.

Methods: Qualitative methods were used.

Clavulanic acid reduces rewarding, hyperthermic and locomotor-sensitizing effects of morphine in rats: a new indication for an old drug?

Background: Despite the efficacy of ceftriaxone (CTX) in animal models of CNS diseases, including drug addiction, its utility as a CNS-active therapeutic may be limited by poor brain penetrability and cumbersome parenteral administration. An alternative is the β-lactamase inhibitor clavulanic acid (CA), a constituent of Augmentin that prevents antibiotic degradation. CA possesses the β-lactam core necessary for CNS activity but, relative to CTX, possesses: (1) oral activity; (2) 2.

Stimulating the lip motor cortex with transcranial magnetic stimulation.

Transcranial magnetic stimulation (TMS) has proven to be a useful tool in investigating the role of the articulatory motor cortex in speech perception. Researchers have used single-pulse and repetitive TMS to stimulate the lip representation in the motor cortex. The excitability of the lip motor representation can be investigated by applying single TMS pulses over this cortical area and recording TMS-induced motor evoked potentials (MEPs) via electrodes attached to the lip muscles (electromyography; EMG).
