Abstract
Background When delivered in person, yoga is effective in managing Irritable Bowel Syndrome (IBS) symptoms. However, research is needed to determine the feasibility and effectiveness of yoga as a therapeutic option when delivered virtually. Aims The aim was to explore the feasibility and effectiveness of a yoga program, delivered virtually, for patients with IBS. We hypothesized the program would be feasible and effective in improving outcomes in the intervention group compared to the control group. Methods Adults diagnosed with IBS were randomized to receive either a Hatha yoga intervention or to an advice-only control group. The intervention consisted of facilitator-led weekly online classes for eight weeks delivered using Microsoft Office Teams and daily home practice. Yoga sessions included sequential delivery of postures, chanting, breathing exercises, and meditation over four weeks, with integrated practice over the final four weeks. Feasibility was evaluated with recruitment and attrition rates, adherence, and safety. The primary outcome was severity of IBS symptoms (IBS-Symptom Severity Score, IBS-SSS). Secondary outcomes included anxiety (General Anxiety Disorder-7), depression (Patient Health Questionnaire-9), and stress (Perceived Stress Scale) assessed at baseline and eight weeks. Unadjusted and adjusted analysis of variance (and covariance) models compared baseline and post-intervention data between groups using intent to treat analysis. Results Sixty-five participants participated (32 treatment, 33 control). The mean age was 44.2±14.1 years and 91% identified as female. Participants had been living with IBS for 11.7±11 years. Fifteen participants were lost to follow-up (20% attrition rate). Participants attended on average 5.9±1.7 out of a possible 8 sessions (74% adherence) and accumulated 1,187±545 minutes in daily practice over eight weeks. No adverse events were reported. The groups did not differ at baseline (P>0.05). From baseline to post intervention, unadjusted ANOVA models indicated the yoga program was not statistically superior to the control group for IBS-symptoms (-17.5 points; 95% CI -62.6 to 27.6; P = 0.440), anxiety (-0.91 points; 95% CI -2.47 to 0.64; P = 0.245) and stress (-0.65 points; 95% CI -1.73 to 0.44; P = 0.239). Significant differences between groups were seen for depression (-1.82 points; 95% CI -3.49 to -0.15; P = 0.033). A second model considered relevant covariates including age, comorbidities, and years since diagnosis (i.e., ANCOVA), and the results were similar to the unadjusted model. Conclusions Our virtual Hatha yoga and mediation program was feasible, and participants showed improvement in their depression scores. However, they did not experience a significant improvement in their IBS symptoms, anxiety, or stress, perhaps due to the short timeframe of the intervention. Funding Agencies None

Abstract
BACKGROUND In neonatal hypoxic ischemic encephalopathy (HIE), hypo- and hyperglycemia have been associated with poor outcomes. However, glucose variability has not been reported in this population. OBJECTIVE To examine the association between serum glucose variability within the first 24 hours and two-year neurodevelopmental outcomes in neonates cooled for HIE. STUDY DESIGN In this retrospective cohort study, glucose, clinical and demographic data were documented from 23 term newborns treated with whole body therapeutic hypothermia. Severe neurodevelopmental outcomes from planned two-year assessments were defined as the presence of any one of the following: Gross Motor Function Classification System levels 3 to 5, Bayley III Motor Standard Score <70, Bayley III Language Score <70 and Bayley III Cognitive Standard Score <70. RESULTS The neurodevelopmental outcomes from 8 of 23 patients were considered severe, and this group demonstrated a significant increase of mean absolute glucose (MAG) change (-0.28 to -0.03, 95% CI, p = 0.032). There were no significant differences between outcome groups with regards to number of patients with hyperglycemic means, one or multiple hypo- or hyperglycemic measurement(s). There were also no differences between both groups with mean glucose, although mean glucose standard deviation was approaching significance. CONCLUSIONS Poor neurodevelopmental outcomes in whole body cooled HIE neonates are significantly associated with MAG changes. This information may be relevant for prognostication and potential management strategies.

Abstract
The management of certain plant beneficial microorganisms [biological control agents (BCAs)] seems to be a promising and environmental friendly method to control plant pathogens. However, applications are still limited because of the lack of consistency of BCAs when they are applied in the field. In the present paper, the advantages and limitations of BCAs are seen through the example of Pythium oligandrum, an oomycete that has received much attention in the last decade. The biological control exerted by P. oligandrum is the result of a complex process, which includes direct effects through the control of pathogens and/or indirect effects mediated by P. oligandrum, i.e. induction of resistance and growth promotion. P. oligandrum antagonism is a multifaceted and target fungus-dependent process. Interestingly, it does not seem to disrupt microflora biodiversity on the roots. P. oligandrum has an atypical relationship with the plant because it rapidly penetrates into the root tissues but it cannot stay alive in planta. After root colonisation, because of the elicitation by P. oligandrum of the plant-defence system, plants are protected from a range of pathogens. The management of BCAs, here P. oligandrum, is discussed with regard to its interactions with the incredibly complex agrosystems.

Abstract
The influence exerted by the biocontrol oomycete Pythium oligandrum on the bacterial populations proliferating in the rhizosphere of tomato plants grown in a hydroponic system and in the circulating solutions is studied in the present experiment. Quantitative PCR and single-strand conformation polymorphism were used to investigate the genetic structure and dynamics of the bacterial communities colonizing the root systems and the various circulating solutions. Quantitative PCR assays showed that bacteria heavily colonized the rhizosphere of tomato plants with, however, no significant density changes throughout the cultural season (April–September). Single strand conformation polymorphism fingerprints revealed the occurrence of transient perturbations in the rhizospheric indigenous bacterial communities following P. oligandrum introduction in the root system of plants. This effect was, however, transient and did not persist until the end of the cropping season. Interestingly, the genetic structure of the bacterial microflora colonizing either the roots or the nutrient solutions evolved throughout the cropping season. This temporal evolution occurred whatever the presence and persistence of P. oligandrum in the rhizosphere. Evidence is also provided that bacterial microflora that colonize the root system are different from the ones colonizing the circulating solutions. The relationships between these 2 microflora (at the root and solution levels) are discussed.

Abstract
AIM Assessment of trabeculectomy in South-East Scotland (SESTS) with comparison to National Survey of Trabeculectomy (NST) and outcomes of consultant and trainee surgery. METHOD A retrospective study of 304 consecutive, primary trabeculectomies, in two Scottish centres (Edinburgh and Dunfermline) with two glaucoma specialists and higher surgical trainees, was performed. The study group had primary open angle glaucoma (65.5%), pseudoexfoliation (6.9%), normal tension glaucoma (7.6%), pigment dispersion syndrome (1.6%), and other complicated glaucoma (18.4%). All patients underwent trabeculectomy by the glaucoma specialist (57.6%) and higher surgical trainee (42.4%) with close scrubbed supervision. RESULTS Compared to the NST, the waiting time for surgery (<3 months) was significantly less in the SESTS (P<0.001). There was also significantly more use of intraoperative antimetabolites (P<0.01), bleb intervention (P<0.001), and a higher rate of early complications (P<0.025). There was no significant difference in outcome at intraocular pressure (IOP)<2/3 listing IOP (qualified and unqualified) between the SESTS and the NST. Significantly, more patients achieved an unqualified success of IOP<21 mmHg (P<0.01) and an unqualified success of IOP<16 mmHg in the SESTS than the NST (P<0.05). At 1 year post surgery, visual loss of greater than one Snellen line was more common in the NST (P<0.01) as was the use of anti-glaucoma medication (P<0.001). Trainee cases returned to theatre more frequently (P<0.025) and merited more bleb intervention (P<0.01) than consultant cases, but the long-term outcome was similar. CONCLUSION Our study highlights significant changes in the practice and outcome of trabeculectomy compared to the national survey conducted a decade ago.
