Abstract
We evaluated the impact of shoreline dynamics on fringing vegetation density at mid- and low-marsh elevations at a high-energy site in the northern Gulf of Mexico. Particularly, we selected eight unprotected shoreline stretches (75 m each) at a historically eroding site and measured their inter-annual lateral movement rate using the DSAS method for three consecutive years. We observed high inter-annual variability of shoreline movement within the selected stretches. Specifically, shorelines retrograded (eroded) in year 1 and year 3, whereas, in year 2, shorelines advanced seaward. Despite shoreline advancement in year 2, an overall net erosion was recorded during the survey period. Additionally, vegetation density generally declined at both elevations during the survey period; however, probably due to their immediate proximity with lateral erosion agents (e.g., waves, currents), marsh grasses at low-elevation exhibited abrupt reduction in density, more so than grasses at mid elevation. Finally, contrary to our hypothesis, despite shoreline advancement, vegetation density did not increase correspondingly in year 2 probably due to a lag in response from biota. More studies in other coastal systems may advance our knowledge of marsh edge systems; however, we consider our results could be beneficial to resource managers in preparing protection plans for coastal wetlands against chronic stressors such as lateral erosion.

Abstract
OBJECTIVE Smartphone-based ecological momentary assessment (EMA), or real-time, repeated sampling of participants' states, behaviors, or experiences over time, is a promising approach to understanding obesity-related behaviors in African-American women-a population with the highest obesity prevalence. In this study, we explored participants' experiences with this methodology. DESIGN AND SAMPLE In this secondary analysis of data, 100 African-American women participated in seven consecutive days of EMA data collection. MEASURES Measures related to acceptability (technical challenges, daily burden, emotional responses, willingness to participate in future studies) and data quality (reporting accuracy, behavior reactivity, adherence), as well as demographics, were collected. RESULTS While there were few demographic differences, women who were unemployed, had the lowest educational levels, or had the lowest per capita income reported the greatest enjoyment with mobile technology-based EMA, while at the same time reporting the highest levels of challenge with use of the equipment. Participants consistently indicated willingness to participate in future EMA studies and indicated that the study method was acceptable. EMA methodology produced data of sufficient quality. CONCLUSION Findings suggest future studies using smartphone-based EMA with African-American women are feasible.

Abstract
This is the first prospective study in a contemporary Australian/New Zealand population to determine the prevalence of testosterone deficiency in testicular cancer survivors at 12 months from treatment, and any association with poorer quality of life. Hormone assays from 54 evaluable patients in a prospective cohort study revealed biochemical hypogonadism in 18 patients (33%) and low-normal testosterone in 13 patients (24%). We found no association between testosterone levels and quality of life (all P > 0.05). Hypogonadal patients should be considered for testosterone replacement to prevent long-term morbidity.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen, and colonisation with this organism can result in localised or systemic infections which may be fatal. One hundred in-patients admitted to a London teaching hospital and 100 out-patients attending prosthetic dentistry clinics were recruited into this study. Of the 100 out-patients, 27 % harboured S. aureus on their dentures, compared to 33 % of in-patients. Only one out-patient had MRSA colonising their dentures whereas 12 % of the in-patients harboured MRSA. The median total bacterial count of the denture plaque samples was 6.2 × 10(7) cfu/sample and 6.9 × 10(7) cfu/sample for the out-patient and in-patient populations, respectively. In most instances, where present, S. aureus comprised less than 1 % of the total viable denture microbiota. Phage typing demonstrated that EMRSA-15 and non-typeable strains were harboured on dentures. The results of this study have revealed that dentures are a potential reservoir of MRSA and so account should be taken of these findings when planning decontamination procedures for elimination of this pathogen.

Abstract
This study examined contributions of environmental and personal factors (specifically, food availability and expense, daily hassles, self-efficacy, positive and negative affect) to within-person and between-person variations in snack food intake in 100 African American women. Participants were signaled at random five times daily for seven days to complete a survey on a study-provided smartphone. Women reported consuming snack foods at 35.2% of signals. Easier food availability accounting for one's usual level was associated with higher snack food intake. Being near outlets that predominately sell snacks (e.g., convenience stores), while accounting for one's usual proximity to them, was associated with higher snack food intake. Accounting for one's usual daily hassle level, we found that on days with more frequent daily hassles snack food intake was higher. The positive association between within-person daily hassles frequency and snack food intake was stronger when foods were easily available. Public and private policies to curb ubiquitous food availability and mobile health interventions that take into account time-varying influences on food choices and provide real-time assistance in dealing with easy food availability and coping with stressors may be beneficial in improving African American women's day to day food choices.

Abstract
Open carpal tunnel release is commonly performed under local anaesthesia. No study has compared intra-operative short- versus long-acting local anaesthetics as preemptive analgesics in carpal tunnel surgery. In this single-blinded prospective study, 100 consecutive carpal tunnel releases were performed by a single surgeon at one institution with either lignocaine (n = 50) or ropivacaine (n = 50). Allocation was performed via the method of alternation. Subjects were given a questionnaire to answer the following: (1) time to first incidence of pain, (2) quality of first night's sleep, and (3) mean numerical pain scores in the first 24 hours. The time to the first postoperative pain was significantly shorter in the lignocaine group (5.58 vs. 9.17 hours, p < 0.035). There were no significant difference in the incidence of poor first night's sleep (16% vs. 26%, p = 0.28) or mean pain scores in the first day (3.6 vs. 2.9, p = 0.16). Existing evidence advocates for long-acting intraoperative local anaesthetic because it results in a longer duration of postoperative analgesia, however, our study suggests that it may also result in a poorer first night's sleep.

Abstract
Member states across the Eastern Mediterranean region face unprecedented health challenges, buffeted by demographic change, a dual disease burden, rising health costs, and the effects of ongoing conflict and population movements - exacerbated in the near-term by instability arising from recent political upheaval in the Middle East. However, health actors in the region are not well positioned to respond to these challenges because of a dearth of good quality health research. This review presents an assessment of the current state of health research systems across the Eastern Mediterranean based on publicly available literature and data sources. The review finds that - while there have been important improvements in productivity in the Region since the early 1990s - overall research performance is poor with critical deficits in system stewardship, research training and human resource development, and basic data surveillance. Translation of research into policy and practice is hampered by weak institutional and financial incentives, and concerns over the political sensitivity of findings. These problems are attributable primarily to chronic under-investment - both financial and political - in Research and Development systems. This review identifies key areas for a regional strategy and how to address challenges, including increased funding, research capacity-building, reform of governance arrangements and sustained political investment in research support. A central finding is that the poverty of publicly available data on research systems makes meaningful cross-comparisons of performance within the EMR difficult. We therefore conclude by calling for work to improve understanding of health research systems across the region as a matter of urgency.

Abstract
BACKGROUND Childhood cancer survivors have a sixfold increased risk of developing subsequent neoplasms when compared to the general population. We sought to describe the occurrence of melanoma as a subsequent neoplasm among adult survivors of childhood cancer. PATIENTS AND METHODS Among 14,358 5-year survivors of childhood cancer diagnosed between 1970 and 1986, we calculated the cumulative incidence, standardized incidence ratio (SIR), and absolute excess risk (AER) of subsequent melanoma. Potential risk factors were assessed using a cause-specific hazards model. RESULTS Fifty-seven melanomas (46 invasive, 2 ocular, and 9 in situ) occurred in 51 survivors. The median time to the development of melanoma was 21.0 years (range: 5.6-35.4 years) and the median age at melanoma was 32.3 years (range: 10.9-49.0 years). Initial cancer diagnoses included soft tissue and bone sarcoma (n = 15), leukemia (13), lymphoma (14), central nervous system malignancy (5), Wilms tumor (3), and neuroblastoma (1). The cumulative incidence of first subsequent melanoma at 35 years from initial cancer diagnosis was 0.55% [95% confidence interval (CI): 0.37-0.73]. The SIR of subsequent invasive malignant melanoma of the skin was 2.42 (95% CI: 1.77-3.23), and the AER was 0.10 (95% CI: 0.05-0.15) per 1,000 person-years. No statistically significant associations were found between melanoma risk and family history of cancer, demographic, or treatment-related factors. CONCLUSION Survivors of childhood cancer have an approximate 2.5-fold increased risk of melanoma. Early screening and prevention strategies are warranted.
