AbstractAimGestational diabetes mellitus is a common complication of pregnancy. Long‐chain polyunsaturated fatty acids (LCPUFA) are essential for fetal neurodevelopment. Docosahexaenoic acid (DHA) is the predominant n–3 LCPUFA in the brain and retina. Circulating absolute concentrations of total n–3 and n–6 LCPUFAs rise during normal pregnancy. It remains unclear whether gestational diabetes may affect the normal rise in circulating concentrations of LCPUFAs in the third trimester of pregnancy – a period of rapid fetal neurodevelopment. This study aimed to address this question.MethodsIn a prospective singleton pregnancy cohort, fatty acids in fasting plasma total lipids were measured at 24–28 and 32–35 weeks of gestation in women with (n = 24) and without gestational diabetes mellitus (n = 116). Fatty acid desaturase activity indices were estimated by relevant product‐to‐precursor fatty acid ratios. Dietary nutrient intakes were estimated by a food frequency questionnaire.ResultsPlasma absolute concentrations of total n–6 LCPUFAs rose significantly between 24–28 and 32–35 weeks of gestation in women with or without gestational diabetes, whereas total n–3 LCPUFAs and DHA concentrations rose significantly only in women without gestational diabetes (all P < 0.01). Delta–5 desaturase indices (20:4n–6/20:3n–6) were similar, but delta–6 desaturase indices (18:3n–6/18:2n–6) were significantly lower in women with gestational diabetes at 32–35 weeks of gestation. Dietary intakes of all fatty acids were comparable.ConclusionThe normal rise in circulating absolute concentrations of DHA and total n–3 LCPUFAs in the third trimester of pregnancy may be compromised in gestational diabetes, probably due to impaired synthesis or mobilization rather than dietary intake difference.
Diversification strategies and firm performance in Vietnam
Authors: Santarelli Enrico , Tran Hien Thu 
Published: October 2015

AbstractThis paper is based upon the assumption that a firm's profitability is determined by its degree of diversification which is, in turn, strongly related to the antecedent decision to carry out diversification activities. This calls for an empirical approach that permits the joint analysis of the three interrelated and consecutive stages of the overall diversification process: diversification decision, degree of diversification and outcome of diversification. We apply parametric and semi‐parametric approaches to control for sample selection and the endogeneity of the diversification decision in both static and dynamic models. For the analysis, we use the census dataset on the whole firm population in Vietnam, as a representative of transition countries. After controlling for industry fixed‐effects, the empirical evidence from the firm‐level data shows that diversification has a curvilinear effect on profitability: it improves firms’ profit up to a point, after which a further increase in diversification is associated with declining performance. This implies that firms should consider optimal levels of product diversification when they expand their product offerings beyond their core business. Other noteworthy findings include the following: (i) the factors that stimulate firms to diversify do not necessarily encourage them to extend their diversification strategy; (ii) firms that are endowed with highly technological resources and innovation investment are likely to successfully exploit diversification as an engine of growth; and (iii) while industry performance does not have a strong influence on the profitability of firms, it impacts their diversification decision as well as the degree of diversification.

AbstractThe obscure mealybug, Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae), is a cosmopolitan pest. In New Zealand, recently introduced management tools include the host‐specific parasitoid Acerophagus maculipennis (Mercet) (Hymenoptera: Encyrtidae) established in 2001, and pheromone‐baited monitoring traps available since 2005. Red delta traps baited with rubber septum lures impregnated with 4.0 μg of the mealybug synthetic sex pheromone, placed in apple orchards in Hawke's Bay and Nelson, trapped both male P. viburni and female A. maculipennis. Two generations of both species per year were discernible, but numbers were low in spring and parasitoids were not trapped during winter (June to September). Male P. viburni catches reached a plateau at a pheromone dose of ca. 1.0 μg per lure but numbers of A. maculipennis per trap increased up to 100 μg per lure, the maximum dose tested. A mathematical model showed that the lures had a half‐life of about 7.4 days and were most attractive to P. viburni with a dose of 0.19 μg, and that the trap effectiveness decreased rapidly once the release rate dropped below the optimum. The model also predicted that the initial pheromone dose should be increased from 0.19 to 5.41 μg per lure as the desired period of deployment increased from 0 to 9 weeks. A dose of 4.0 μg had an initial relative effectiveness of about 55%, reached peak effectiveness after about 5 weeks, and fell to 55% relative effectiveness again after about 8.3 weeks. We conclude that an initial pheromone load of 4.0 μg is appropriate for practical monitoring of P. viburni during the New Zealand summer. Future applications of the sex pheromone for managing the pest and parasitoid are discussed.
Effects of elicitors of host plant defenses on pear psylla, Cacopsylla pyricola
Authors: Cooper W. Rodney , Horton David R. 
Published: October 2015

AbstractPear psylla, Cacopsylla pyricola (Foerster) (Hemiptera: Psyllidae), is a key pest of cultivated pear [Pyrus communis L. (Rosaceae)] in North America and Europe. We examined the effects of foliar applications of three commercially available chemical elicitors of host‐plant defenses — Actigard (acibenzolar‐S‐methyl), Employ (harpin protein), and ODC (chitosan) — on survival, development, feeding, and egg laying of C. pyricola. All three defense elicitors reduced the number of nymphs present on pear (cvs. Bartlett or D'Anjou) 30 days after releasing 10 adults on the trees. Choice assays showed that females settled and oviposited on untreated trees more often than on trees treated with any of the three defense elicitors. Results of no‐choice assays confirmed that the effects of Actigard, Employ, and ODC on C. pyricola were due to activation of systemic plant responses that led to reduced oviposition preference and nymph survival. However, results did not provide evidence that plant responses to elicitors led to reduced nymphal feeding rates or development. Results of our laboratory studies suggest that commercial defense elicitors may be useful in the integrated management of pear psylla once the effects of elicitors at an ecological scale are better understood.

AbstractBackgroundExtramedullary disease in multiple myeloma patients is an uncommon event occurring either at the time of diagnosis, or during disease progression/relapse. This manifestation is frequently associated with poor outcome and resistance to treatment. We evaluated chromosomal alterations of plasma cells of multiple myeloma patients with extramedullary relapse, either in the bone marrow (BM) or at extramedullary sites, and in previous BM collection by interphase fluorescence in situ hybridization.Material and methodsThirty‐one patients [25 BM plasma cells (BMPCs), 18 extramedullary tumor plasma cells], of which 12 had paired samples of BM and extramedullary plasma cells and 14 had previous collection of BM, were investigated for the presence of chromosomal aberrations (CHAs): del(17)(p13), del(13)(q14), 14q32 disruption, t(4;14)(p16;q32), t(14;16)(q32;q23), gain(1)(q21), and hyperdiploidy status.ResultsOverall, in unrelated samples, t(4;14) was more prevalent in extramedullary plasma cells, and hyperdiploidy was more frequent in BMPCs. In paired samples, there was a higher frequency of del(13)(q14) and 14q32 disruption in BMPCs. Frequency of all studied CHAs was higher in BMPCs of extramedullary patients than in their previous sample collection.ConclusionThese data show that plasma cells harbor more aberrations during their transformation into extramedullary form.
Do Investors Trade around Social Rating Announcements?

Published: October 2015

AbstractThis paper investigates trading around Corporate Social Responsibility (CSR) rating announcements. Focusing on CSR rating announcements made by Vigeo on European markets, we use Euronext intraday data to prove that trading volume drops sharply before announcements and increases afterwards. Willingness to trade depends mainly on prior private information and the content of the announcement. Our results show effects from disaggregated scores, but not from overall scores. More specifically, we find that some topics like business behaviour, human resources and human rights significantly influence investor trades. Environmental risk does not have an impact on trading behaviour.

AbstractGene flow from plantations of nonlocal (genetically exotic) tree provenances into natural stands of the same species is probably a widespread phenomenon, but its effects remain largely unexamined. We investigated early fitness consequences of intraspecific exotic gene flow in the wild by assessing differences in survival among native, nonlocal, and F1 intraspecific hybrid seedlings naturally established within two native pine relicts (one of Pinus pinaster and the other of P. sylvestris) surrounded by nonlocal plantations. We obtained broad‐scale temporally sequential genotypic samples of a cohort of recruits in each pine relict, from seeds before dispersal to established seedlings months after emergence, tracking temporal changes in the estimated proportion of each parental cross‐type. Results show significant proportions of exotic male gametes before seed dispersal in the two pine relicts. Subsequently to seedling establishment, the frequency of exotic male gametes became nonsignificant in P. pinaster, and dropped by half in P. sylvestris. Exotic zygotic gene flow was significantly different from zero among early recruits for P. sylvestris, decreasing throughout seedling establishment. Seedling mortality resulted in small late sample sizes, and temporal differences in exotic gene flow estimates were not significant, so we could not reject the null hypothesis of invariant early viability across parental cross types in the wild.
Prevention of post operative complications following surgical treatment of equine colic: Current evidence
Authors: Salem S. E. , Proudman C. J. , Archer D. C. 
Published: October 2015

SummaryChanges in management of the surgical colic patient over the last 30 years have resulted in considerable improvement in post operative survival rates. However, post operative complications remain common and these impact negatively on horse welfare, probability of survival, return to previous use and the costs of treatment. Multiple studies have investigated risk factors for post operative complications following surgical management of colic and interventions that might be effective in reducing the likelihood of these occurring. The findings from these studies are frequently contradictory and the evidence for many interventions is lacking or inconclusive. This review discusses the current available evidence and identifies areas where further studies are necessary and factors that should be taken into consideration in study design.
Consumer awareness and willingness to pay for safety of street foods in developing countries: a review

Published: October 2015

AbstractStreet food vending is still popular in developing countries despite the giant stride recorded in the areas of food processing and global food supply in the last century. Its contribution to the socio‐economic development of the countries is evidenced by the volume of trade involved and provision of employment for significant portion of rural and urban populace. However, there has been persistent global concern on the risks of street food to the health of consumers because of the attitudes of practitioners throughout the chain. This review summarizes the findings of studies on awareness and perceptions of street food consumers to the hazards involved in street food, and their willingness to pay (WTP) premium for safety intervention. The major limitation to WTP is the extra cost that could result from the implementation of reports of WTP studies which could disenfranchise those consumers that may not be able to afford the premium. This review, therefore, recommends the formulation and enforcement of appropriate public policies that would cover the entire chain of street food vending for the safety of everybody along the chain and the protection of the health of the consumers.
Ergonomics in hair restoration surgeons

Published: October 2015

SummaryBackgroundMusculoskeletal disorders (MSDs) are potential sources of morbidity in hair restoration surgeons (HRS). This is particularly true for those who perform follicular unit extraction (FUE).ObjectiveTo describe the nature, prevalence, and extent of ergonomic or work‐related MSDs among HRS.Methods & MaterialsA survey regarding MSDs was e‐mailed to 100 HRS.ResultsThirty‐eight HRS completed the survey, the majority of which were male and between the ages of 50–69. Fifty percent of respondents reported musculoskeletal symptoms occurring during or after hair restoration procedures. Reports of pain during and after surgery were higher for FUE procedures than single strip excision procedures. Pain/fatigue/discomfort persisted for longer following FUE procedures compared to strip excision procedures. MSD symptoms also negatively impacted quality of life. Although the majority of respondents felt that ergonomics was important, only 30% use ergonomic support when performing FUE procedures.ConclusionHair restoration surgeons should be aware of MSD symptoms and particularly when performing FUE. Symptoms reported included pain, fatigue, and discomfort, sometimes lasting several hours following surgery. More attention needs to be paid to ergonomics during hair restoration procedures in order to improve the quality of life of surgeons and ultimately prevent the development of MSDs.

SummarySwallowing disorders are a growing problem among the elderly in long‐term care (LTC), and they can cause aspiration pneumonia. In order to detect swallowing disorders early, simple tools are needed to assess aspiration and silent aspiration (SA). To compile a sample of elderly people requiring LTC, and categorise them as having suspected aspiration and/or SA using simple screening tools. In addition, oral ability, severity of dementia, vital functions and nutritional status were compared in these groups. A total of 393 elderly people in LTC (89 men and 304 women; age ranging from 65 to 100 years) were included in the study. The modified water swallow test, cervical auscultation and cough test were used to assess swallowing function. The participants were categorised as having suspected aspiration and/or SA, and the following assessments were performed: (i) oral ability (lips function, tongue function, rinsing and gargling ability), (ii) dementia severity, (iii) vital functions and (iv) nutritional status. Suspected aspiration was apparent in 50·5% of patients, of which 24·0% had suspected SA. Those with suspected aspiration showed worsened oral ability, dementia severity, vital functions and nutritional status. Similarly, those with suspected SA showed worsened dementia severity, vital functions and nutritional status. Logistic regression analysis revealed that lip closure, lingual movement and rinsing ability were significantly associated with suspected aspiration. Dementia severity was the best predictor of suspected SA. Simple screening tools can be used to identify suspected aspiration and SA, which may facilitate early detection of aspiration pneumonia or swallowing disorder risk.

SummaryThe previous reports suggest that obstructive sleep apnoea (OSA) is related to metabolic syndrome, mineral metabolism disorders and cardiovascular disease. In addition, a possible relationship between obesity and the calcification of ligaments has been implied. However, the potential link between OSA and the calcification of ligaments has not been directly studied. In this present study, to investigate the potential link between OSA and the calcification of ligaments, we examined the prevalence of the calcification of ligaments in OSA patients and the relationship between these findings and OSA severity. Eighty consecutive patients (60 males, 20 females) diagnosed as OSA or a heavy snorer based on full‐night polyso‐mnography were retrospectively recruited from May 2006 to July 2008. Each patient underwent cephalometric imaging examination before the arrangement of an oral appliance. One calibrated observer (YS) reviewed the cephalometric images for the presence of calcification of the nuchal ligament and osteophytes of the cervical spine. The prevalence of calcification of the nuchal ligament in OSA patients and snorers was 46·3% (males: 52%, females: 30%) There was a significant positive correlation between the severity of OSA (AHI) and the calcification of the nuchal ligament before and after adjusting for BMI. The prevalence of the calcification of the nuchal ligament in OSA subjects and snorers was higher than in previous studies with non‐OSA subjects. In addition, it is suggested that the severity of OSA correlates with the presence of calcification of the nuchal ligament.

Summary18F‐fluoride positron emission tomogra‐phy (PET) can identify subtle functional variation prior to the major structural change detectable by X‐ray. This study aims to investigate the mechanobiological bone reaction around the abutment tooth and in the residual ridge, induced by insertion of removable partial denture (RPD) within two different groups of patients: patients without denture experience (Group 1) and patients with denture experience before (Group 2), using 18F‐fluoride PET imaging technique. 18F‐fluoride PET/computerised tomography (CT) scan was performed to examine the bone metabolic change in mandible before and after the RPD treatment. Region of interests (ROIs) were placed in alveolar bone around abutment tooth and in residual bone beneath the RPD. Standardised uptake value (SUV), reflecting the accumulation of 18F‐fluoride, was measured for each ROI. In all subjects of Group 1, SUVs after insertion were higher than before in both alveolar bone and residual bone, while there was less significant change in SUV in subjects of Group 2. This study demonstrated using longitudinal 18F‐fluoride PET scans to effectively examine the bone metabolic change in mandible induced by occlusal loading after RPD insertion. Using this technique, within the six subjects in this study, it was shown that bone metabolism around abutment tooth and residual ridge increased after RPD insertion in case of first‐time denture user, while there was no big change in the patient with experience of denture before. This study revealed the effectiveness of applying PET to evaluate bone metabolic activity as mechanobiolo‐gical reaction.
Using the Whole School, Whole Community, Whole Child Model: Implications for Practice

Published: October 2015

ABSTRACTBACKGROUNDSchools, school districts, and communities seeking to implement the Whole School, Whole Community, Whole Child (WSCC) model should carefully and deliberately select planning, implementation, and evaluation strategies.METHODSIn this article, we identify strategies, steps, and resources within each phase that can be integrated into existing processes that help improve health outcomes and academic achievement. Implementation practices may vary across districts depending upon available resources and time commitments.RESULTSObtaining and maintaining administrative support at the beginning of the planning phase is imperative for identifying and implementing strategies and sustaining efforts to improve student health and academic outcomes. Strategy selection hinges on priority needs, community assets, and resources identified through the planning process. Determining the results of implementing the WSCC is based upon a comprehensive evaluation that begins during the planning phase. Evaluation guides success in attaining goals and objectives, assesses strengths and weaknesses, provides direction for program adjustment, revision, and future planning, and informs stakeholders of the effect of WSCC, including the effect on academic indicators.CONCLUSIONSWith careful planning, implementation, and evaluation efforts, use of the WSCC model has the potential of focusing family, community, and school education and health resources to increase the likelihood of better health and academic success for students and improve school and community life in the present and in the future.
