Yeast and microalgae are microorganisms with widely diverging physiological and biotechnological properties. Accordingly, their fields of applications diverge: yeasts are primarily applied in processes related to fermentation, while microalgae are used for the production of high-value metabolites and green technologies such as carbon capture. Heterotrophic–autotrophic systems and synthetic ecology approaches have been proposed as tools to achieve stable combinations of such evolutionarily unrelated species. We describe an entirely novel synthetic ecology-based approach to evolve co-operative behaviour between winery wastewater isolates of the yeast Saccharomyces cerevisiae and microalga Chlorella sorokiniana. The data show that biomass production and mutualistic growth improved when co-evolved yeast and microalgae strains were paired together. Combinations of co-evolved strains displayed a range of phenotypes, including differences in amino acid profiles. Taken together, the results demonstrate that biotic selection pressures can lead to improved mutualistic growth phenotypes over relatively short time periods. [ABSTRACT FROM AUTHOR]

Background: During 2009, there were 3.3 million outpatient attendances at outpatient clinics across Ireland. Up to 20 % of these are directed towards ENT services. Aims: To determine the compliance rate of general practitioners with the ICGP referral guidelines. Methods: One-hundred referrals received were compared to the ICGP standardised form and graded accordingly. Each referral letter was graded to a maximum of 37 points. Results: The average score recorded for referrals was 16/37. The referrer detail section scored the highest with a mean of 75.42 % (paediatric referrals) and 72.9 % (adult referrals). The clinical information provided demonstrated compliance rates of 34 % (paediatrics) and 35 % (adults). In total, only 32 letters made any reference to findings on examination. Both paediatric and adult referrals scored an average of 42 % when patients' details are considered. Conclusion: This study demonstrates poor compliance rates with the introduced ICGP standardised referral form, which has implications for the accurate grading of referral letters received.

Background:Glomangiopericytoma is a rare sinonasal tumour of perivascular myoid phenotype, which accounts for less than 1 per cent of all sinonasal tumours.Objective:Discussion of the clinical presentation, histopathological features and advances in the management of sinonasal and skull base glomangiopericytoma.Case report:A 32-year-old woman presented with worsening nasal obstruction, anosmia, severe frontal headaches and right-sided proptosis. Radiographic and endoscopic examination revealed a right-sided, vascular mass involving the nasal cavity, paranasal sinuses and anterior skull base. Histopathological features were consistent with a glomangiopericytoma. Complete endoscopic resection with free margins was achieved.Conclusion:Glomangiopericytomas are rare, vascular, sinonasal tumours. Successful management depends on complete resection, traditionally achieved via an open approach. However, recent advances in endoscopic surgical approaches have enabled complete endoscopic resection of these tumours, minimising morbidity and facilitating subsequent surveillance of the operative site.

Objectives:To determine whether procedure-specific brochures improve patients' pre-operative knowledge, to determine the amount of information expected by patients during the consenting process, and to determine whether the recently proposed ‘Request for Treatment’ consenting process is viable on a large scale.Method:A prospective, questionnaire-based study of 100 patients admitted for selected, elective surgical procedures.Results:In total, 99 per cent of patients were satisfied with the information received in the out-patient department, regarding the proposed procedure. However, 38 per cent were unable to correctly state the nature of the surgery or specific procedure they were scheduled to undergo. Although the vast majority of patients were able to state the intended benefits to be gained from the procedure, only 54 per cent were able to list at least one potential complication, and 80 per cent indicated that they wished to be informed about all potential complications, even if these occurred in less than 1 per cent of cases.Conclusions:The introduction of procedure-specific brochures improved patients' pre-operative knowledge. Although the failings of current consenting practice are clear, the Request for Treatment consenting process would not appear to be a viable alternative because of the large number of patients unable to accurately recall the nature of the proposed surgery or potential complications, following consent counselling.

Background. Recent evidence suggests that the prevalence of postnatal depression (PND) is highest in low-income developing countries. This study aimed to estimate the prevalence of PND and its associated risk factors among Bangladeshi women. Method. The study was conducted in the Matlab subdistrict of rural Bangladesh. A cohort of 346 women was followed up from late pregnancy to post-partum. Sociodemographic and other related information on risk factors was collected on structured questionnaires by trained interviewers at 34-35 weeks of pregnancy at the woman's home. A validated local language (Bangla) version of the Edinburgh Postnatal Depression Scale (EPDS-B) was used to measure depression status at 34-35 weeks of pregnancy and at 6-8 weeks after delivery. Results. The prevalence of PND was 22% [95% confidence interval (CI) 17.7-26.7%] at 6-8 weeks post-partum. After adjustment in a multivariate logistic model, PND could be predicted by history of past mental illness [odds ratio (OR) 5.6, 95% CI 1.1-27.3], depression in current pregnancy (OR 6.0, 95% CI 3.0-12.0), perinatal death (OR 14.1, 95% CI 2.5-78.0), poor relationship with mother-in-law (OR 3.6, 95% CI 1.1-11.8) and either the husband or the wife leaving home after a domestic quarrel (OR 4.0, 95% CI 1.6-10.2). Conclusions. The high prevalence of PND in the study was similar to other countries in the South Asian region. The study findings highlight the need for programme managers and policy makers to allocate resources and develop strategies to address PND in Bangladesh. [ABSTRACT FROM AUTHOR]

A new Alboglossiphonia species from Egypt is described and figured. This leech is placed in the genus Alboglossiphonia on the basis of having three pairs of eyes, diffuse salivary glands, seven pairs of crop caeca, and the attachment of its eggs to the venter. It differs from other Alboglossiphonia species with seven pairs of crop caeca in its combination of very prominent dorsal papillae, two annuli between the gonopores, lobed first six pairs of crop caeca, and paired ducts of male system at peak of activity with conspicuously differentiated sperm duct, seminal vesicle and ejaculatory duct regions.

Hemiclepsis quadrata, which is the only representative of the genus so far reported in Africa, is redescribed. Illustrations showing the diagnostic features of the taxon are provided for the first time. A thorough study of the holotype and one of the paratypes, as well as additional specimens, revealed that Moore overlooked certain important taxonomic features when he described the leech as a Batracobdella species. The transfer of this species to the genus Hemiclepsis is based on the following features exhibited by this leech: dilated head region, three pairs of eyes, central proboscis pore, ten pairs of crop caeca and small genital atria.

Paediatric blunt laryngeal trauma is infrequently encountered; however, it can have fatal consequences ifmanaged inappropriately. This paper provides an overview of the relatively limited literature available on the subject and highlights current controversies and recent advances in the management of these injuries.
