- The identification and annotation of protein-coding genes is one of the primary goals of whole-genome sequencing projects, and the accuracy of predicting the primary protein products of gene expression is vital to the interpretation of the available data and the design of downstream functional applications. Nevertheless, the comprehensive annotation of eukaryotic genomes remains a considerable challenge. Many genomes submitted to public databases, including those of major model organisms, contain significant numbers of wrong and incomplete gene predictions. We present a community-based reannotation of the Aspergillus nidulans genome with the primary goal of increasing the number and quality of protein functional assignments through the careful review of experts in the field of fungal biology.

- Synthesis centers offer a unique amalgam of culture, infrastructure, leadership, and support that facilitates creative discovery on issues crucial to science and society. The combination of logistical support, postdoctoral or senior fellowships, complex data management, informatics and computing capability or expertise, and most of all, opportunity for group discussion and reflection lowers the "activation energy" necessary to promote creativity and the cross-fertilization of ideas. Synthesis centers are explicitly created and operated as community-oriented infrastructure, with scholarly directions driven by the ever-changing interests and needs of an open and inclusive scientific community. The last decade has seen a rise in the number of synthesis centers globally but also the end of core federal funding for several, challenging the sustainability of the infrastructure for this key research strategy. Here, we present the history and rationale for supporting synthesis centers, integrate insights arising from two decades of experience, and explore the challenges and opportunities for long-term sustainability.

- Purpose: Osteoradionecrosis (ORN) of the mandible is a serious complication of head and neck radiotherapy. This study aims to investigate the effect of hyperbaric oxygen (HBO) treatment on ORN in two randomized, controlled multicentre trials. Methods and materials: Patients with ORN with indication for surgical treatment were randomised to either group 1: surgical removal of necrotic mandibular bone supplemented by 30 pre- and 10 postoperative HBO exposures at 243 kPa for 90 min each, or group 2: surgical removal of necrotic bone only. Primary outcome was healing of ORN one year after surgery evaluated by a clinically adjusted version of the Common Toxicity Criteria of Adverse Events (CTCAE) v 3.0. Secondary outcomes included xerostomia, unstimulated and stimulated whole salivation rates, trismus, dysphagia, pain, Activities of Daily Living (ADL) and quality of life according to EORTC. Data were combined from two separate trials. Ninety-seven were enrolled and 65 were eligible for the intent-to-treat analysis. The 33% drop-out was equally distributed between groups. Results: In group 1, 70% (21/30) healed compared to 51% (18/35) in group 2. HBO was associated with an increased chance of healing independent of baseline ORN grade or smoking status as well as improved xerostomia, unstimulated whole salivary flow rate, and dysphagia. Due to insufficient recruitment, none of the endpoints reached a statistically significant difference between groups. ADL data could only be obtained from 50 patients. Conclusion: Hyperbaric oxygen did not significantly improve the healing outcome of osteoradionecrosis after surgical removal of necrotic bone as compared to standard care (70% vs. 51%). This effect is not statistically significant due to the fact that the study was underpowered and is therefore prone to type II error. © 2021 The Authors

Physical EXercise Augmented COGnitive Behaviour Therapy for Older Adults with Generalised Anxiety Disorder (PEXACOG)
- 2016
-
Konferensbidrag (refereegranskat)abstract
- Generalised anxiety disorder (GAD) is the most prevalent severe anxiety disorder among older adults. The disorder has a pervasive influence on the lives of those affected, and is a risk factor for other severe disorders such as depression, dementia and coronary heart disease. Cognitive behaviour therapy (CBT) is the treatment of choice for this disorder, but older adults have shown reduced effect of treatment compared to working age adults. Physical exercise has been suggested as intervention to improve the effects of treatment for GAD, via its demonstrated positive effect on cognitive functioning, increased plasticity in the brain, and increased availability of neurotrophins important for extinction of fear associations. The aim of the current research project is to investigate whether augmenting CBT with physical exercise will lead to improved effects of CBT on GAD in older adults in a randomized controlled trial (RCT). Participants between 60-75 years of age with a primary diagnosis of GAD will be randomised to one of two treatment conditions. The effects of treatment will be assessed on outcome measures, biological, physiological and cognitive measures at pre- interim-, and post-treatment, and follow-up assessments at 6- and 12-months post intervention. Participants in both groups will receive five weeks of pre-treatment intervention consisting of either physical exercise or weekly telephone contact. Participants thereafter receive either ten weeks of manualised CBT for GAD combined with manualised physical exercise or ten weeks of manualised CBT for GAD combined with weekly telephone contact. We expect that the treatment effect of the physical exercise augmented CBT will be greater than that of CBT combined with weekly telephone contact, as measured by a reduction in GAD symptoms on the Penn State Worry Questionnaire and in the proportion of remitted patients. The study also aims to determining the possible beneficial and augmenting properties of physical exercise in combination with CBT, and our understanding of clinical characteristics of GAD and mechanisms involved in treatment effect. Treatment rationale, procedures and protocols will be presented in detail together with preliminary results from the initial feasibility study comprises eight participants.

OralDisk: A Chair-Side Compatible Molecular Platform Using Whole Saliva for Monitoring Oral Health at the Dental Practice

- Periodontitis and dental caries are two major bacterially induced, non-communicable diseases that cause the deterioration of oral health, with implications in patients’ general health. Early, precise diagnosis and personalized monitoring are essential for the efficient prevention and management of these diseases. Here, we present a disk-shaped microfluidic platform (OralDisk) compatible with chair-side use that enables analysis of non-invasively collected whole saliva samples and molecular-based detection of ten bacteria: seven periodontitis-associated (Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Fusobacterium nucleatum, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola) and three caries-associated (oral Lactobacilli, Streptococcus mutans, Streptococcus sobrinus). Each OralDisk test required 400 µL of homogenized whole saliva. The automated workflow included bacterial DNA extraction, purification and hydrolysis probe real-time PCR detection of the target pathogens. All reagents were pre-stored within the disk and sample-to-answer processing took < 3 h using a compact, customized processing device. A technical feasibility study (25 OralDisks) was conducted using samples from healthy, periodontitis and caries patients. The comparison of the OralDisk with a lab-based reference method revealed a ~90% agreement amongst targets detected as positive and negative. This shows the OralDisk’s potential and suitability for inclusion in larger prospective implementation studies in dental care settings.

- BACKGROUND: Anti-Müllerian Hormone (AMH) has been suggested as a marker for ovarian function. Cadmium and lead have been suggested to reduce female fecundity. In this study we aimed to investigate whether environmental exposure to cadmium and lead was associated with alterations in serum-AMH.MATERIALS AND METHOD: The associations between serum-AMH and whole blood cadmium or lead were investigated by general linear models in a population-based sample of 117 pregnant women.RESULTS: The mean concentrations of blood cadmium and lead were 0.71μg/L and 17.4μg/L, respectively. The mean serum-AMH was 17.3pmol/L. No association between lead and AMH was detected. In the cadmium analysis the adjusted mean AMH level (95% CI) in the highest exposure tertile was 12.4 (6.4;23.8) compared to 5.6 (2.7;11.4) in the lowest exposure tertile (p=0.06).CONCLUSION: The study provides suggestive evidence that environmental exposure to cadmium, but not lead, may alter the level of AMH.
