title: Data publication: Selective removal of Gallium from mixed metal solutions with Arsenic by ion flotation using the biosurfactant rhamnolipid

description: Rhamnolipids have received great attention in various environmental applications in terms of metal complexation and recovery. However, the influence of metal ions on the interfacial, foaming, and ion flotation properties of rhamnolipid are poorly investigated. In this study we investigated the effect of metal ions alone and in a mixed metal system on the interfacial and foaming properties of rhamnolipid. Further, the potential of rhamnolipid to recover and separate Gallium from a mixed metal system containing Gallium (Ga) and Arsenic (As) using bioionflotation has been investigated. The effect of operating parameters like pH, rhamnolipid concentration, and airflow rate were tested and found to have a significant influence on the separation performance. The maximum removal of Ga could reach 74 % when rhamnolipid concentration was 0.85 mM at pH 6 and an airflow rate of 80 ml/min. The selectivity index of Ga over As was highest (17.2) at 0.85 mM rhamnolipid concentration, pH 6, and an airflow rate of 40 ml/min. Also, the selective separation of Ga was dependent on the recovery of water from the foam. The results showed that rhamnolipid biosurfactant acted as a highly efficient ion collector for Ga and the optimized process parameters could be expected to provide very efficient separation and recovery of target metal via ion flotation.

title: Supplementary Material for: Visualization and Identification of Silicone Oil Emulsification Using Dynamic Infrared Confocal Scanning Laser Ophthalmoscopy

description: Silicone oil (SO) plays a key-role as an intraocular tamponade in managing complex vitreoretinal diseases. However, its emulsification can lead to severe irreversible anterior and posterior segment complications. Traditional imaging often struggles to visualize SO, necessitating advanced techniques. This study aimed to introduce and evaluate the use of dynamic infrared confocal scanning laser ophthalmoscopy (IRcSLO) in imaging SO and its emulsification. Two patients, post pars plana vitrectomy with SO injection for retinal detachment, were imaged and recorded using the Heidelberg Retina Tomography Spectralis IRcSLO, focusing on the visualization of SO status and emulsified droplets. IRcSLO imaging technique effectively visualized emulsified SO droplets, even in cases where SO was removed. The droplets were identified as micron-sized, spherical entities, with non-uniform distribution. Case presentations highlighted the variability in SO emulsification patterns and the technique's ability to detect even tiny, emulsified droplets. Therefore, dynamic IRcSLO emerges as a potent imaging modality for SO emulsification visualization. It offers insights into droplet count, motility, and localization within the vitreous cavity. This technique holds promise for future studies focusing on emulsification timing, contributing factors, and potential preventive measures. It also offers a deeper understanding of emulsified SO droplet dynamics across different SO viscosities.

title: Foundation phase teachers on the use of digital play in teaching Mathematics in the early grades

description: The school that was purposefully selected for this study was a technology rich school located in a well established urban neighbourhood. Many of the learners attending this school came from middle income homes. The researcher then proceeded to draw a sample of five grade R– 3 teachers. From this sample, one of the teachers taught a special needs class, while another taught a remedial class. In this way, the study was able to make comparisons and determine how a specific classroom setting contributes to the type and level of engagement by the teachers with digital play.
Data were collected through semi-structured interviews and document analysis of classroom materials and lesson plans. The data analysis considered teacher views on the role of information and communication technology (ICT) in education, digital games and the extent to which digital pedagogies can enhance mathematical skills.The biographical information about the participants, such as their gender, home language, academic and professional qualifications, foundation phase specialisation as well as years of teaching experience were sourced from the participants. All this information was helpful in the analysis of the research participant's personal and professional backgrounds in relation to their knowledge and experience in teaching the foundation phase.

title: Supplementary Material for: Role of pre-surgical gut microbial diversity in Roux-en-Y gastric bypass weight-loss response: A cohort study

description: Introduction: Roux-en-Y gastric bypass substantially alters the gut microbial composition which could be associated with the metabolic improvements seen after surgery. Few studies have been conducted in Latin American populations, such as Mexico where obesity prevalence is above 30% in the adult population. Thus, the aim of this study was to characterize the changes in gut microbiota structure in a Mexican cohort before and after Roux-en-Y gastric bypass and to explore whether surgery-related changes in the microbial community were associated with weight loss.
Methods: Biological samples from patients who underwent Roux-en-Y gastric bypass were examined before and 12 months after surgery. Fecal microbiota characterization was performed through 16S rRNA sequencing. 
Results: Twenty patients who underwent Roux-en-Y gastric bypass showed a median excess weight loss of 66.8% 12 months after surgery. Surgery increased alpha diversity estimates (Chao, Shannon index and observed operational taxonomic units (OTUs), p&lt;0.05), and significantly altered gut microbiota composition. Abundance of four genera were significantly increased after surgery: Oscillospira, Veillonella, Streptococcus, and an unclassified genus from Enterobacteriaceae family (PFDR&lt;0.1). The change in Veillonella abundance was associated with lower excess weight loss (rho=-0.446, p=0.063) and its abundance post-surgery with a greater BMI (rho=0.732, P=5.4x10-4). In subjects without type 2 diabetes lower bacterial richness and diversity before surgery were associated with a greater Veillonella increase after surgery (p&lt;0.05), suggesting that a lower bacterial richness before surgery could favor the bloom of certain oral-derived bacteria that could negatively impact weight loss.
Conclusion: Pre-surgical microbiota profile may favor certain bacterial changes associated with less successful results.

title: Supplementary Material for: Mortality and lithium-protective effects after first-episode mania diagnosis in bipolar disorder: A nationwide retrospective cohort study in Taiwan

description: Introduction: This study aimed to estimate all-cause mortality in patients after a first episode mania (FEM) and examine whether six guideline-recommended medications can reduce mortality.
Methods: The cohort included population-based FEM samples and matched controls from Taiwan, spanning 2007 to 2018. The primary outcomes assessed were all-cause/suicide-related mortality, while the secondary outcome focused on mortality associated with pharmacological treatments. We compared mortality in post-FEM patients and age-/sex-matched controls without any diagnosed bipolar disorders, and patients with and without psychopharmacological treatment using Cox regression analysis, respectively. Statistics were presented with time-to-event adjusted hazard ratios (AHR) and 95% confidence intervals (CIs).
Results: The study included 54,092 post-FEM patients and 270,460 controls, totaling 2,467,417 person-years of follow-up. Post-FEM patients had higher risks of all-cause mortality (AHR 2.38, 95% CI 2.31–2.45) and suicide death (10.80, 5.88-19.84) than controls. Lithium (0.62, 0.55–0.70), divalproex (0.89, 0.83–0.95), and aripiprazole (0.81, 0.66–1.00) were associated with reduced all-cause mortality compared to non-users. There were no significant all-cause mortality differences for quetiapine (0.95, 0.89–1.01), risperidone (0.92, 0.82–1.02), and paliperidone (1.24, 0.88–1.76) users. When accounting for drug action onset times in sensitivity analyses, only lithium significantly reduced all-cause mortality (AHR range 0.65–0.72). There were 35 and 16 suicide deaths in post-FEM patients and controls, respectively. No drug had a significant effect on suicide deaths (lithium: 6; divalproex: 7; aripiprazole: 0; quetiapine: 10; risperidone: 4; paliperidone: 1). 
Conclusion: Post-FEM patients had a higher risk of all-cause/suicide-related mortality, and lithium treatment might reduce all-cause mortality.

title: Supplementary Material for: Early feeding for the prevention of neonatal hypoglycaemia: a systematic review and meta-analysis

description: Background: Poor feeding, among other factors, predisposes neonates to hypoglycaemia. Early feeding is widely recommended to prevent hypoglycaemia in those at risk, but the effectiveness of this is uncertain. This review aimed to summarise and analyse the evidence on the effectiveness of early feeding for prevention of neonatal hypoglycaemia. 
Methods: Four databases and three clinical trials registries were searched from inception to 24th May 2023. Published and unpublished randomised controlled trials (RCTs), quasi-RCTs, cluster randomised trials, non-randomised studies of interventions, and observational studies with comparison groups were considered for inclusion with no language or publication date restrictions. We included studies of neonates who were fed early (within 60 minutes of birth or study defined) versus delayed. Study quality was assessed using the Cochrane Risk of Bias 1 tool or Effective Public Health Practice Project Quality Assessment tool. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. RevMan 5.4.1 or R were used to synthesise results in random-effects meta-analyses. This review was registered prospectively with PROSPERO (CRD42022378904).
Results: A total of 175,392 participants were included across 19 studies, of which two were RCTs, 14 cohort studies, two cross-sectional studies, and one a case-control study. Most studies (13/19) were conducted in low- or lower-middle-income countries. Early feeding may be associated with reduced neonatal hypoglycaemia (four cohort studies, 744 infants, OR 0.19 (95% CI: 0.10 to 0.35), p&lt;0.00001, I2 = 44%) and slightly reduced duration of initial hospital stay (one cohort study, 1,673 infants, MD -0.20 days (95% CI: -0.31 to -0.09), p=0.0003), but the evidence is very uncertain. One RCT found early feeding had little or no effect on the risk of neonatal mortality, but three cohort studies found early feeding may be associated with reduced risk (136,468 infants, OR 0.51 (95% CI: 0.37 to 0.72); low certainty evidence; p&lt;0.0001; I2=54%). 
Conclusion: We found that early feeding may reduce the incidence of neonatal hypoglycaemia, but the evidence is very uncertain. Given its many other benefits, early feeding should continue to be recommended.

title: Greater_North_Sea_Contaminants_aggregated_datasets_1973/2021_v2023

description: EMODnet Chemistry aims to provide access to marine chemistry datasets and derived data products concerning eutrophication, acidity and contaminants. The importance of the selected substances and other parameters relates to the Marine Strategy Framework Directive (MSFD). This aggregated dataset contains all unrestricted EMODnet Chemistry data on potential hazardous substances, despite the fact that some data might not be related to pollution (e.g. collected by deep corer). Temperature, salinity and additional parameters are included when available. It covers the Greater North Sea and Celtic Seas. Data were harmonised and validated by the 'Aarhus University, Department of Bioscience, Marine Ecology Roskilde' in Denmark.
The dataset contains water (profiles), sediment (profiles) and biota (profiles and timeseries). The temporal coverage is 1970–2021 for water measurements, 1973–2021 for sediment measurements and 1979–2021 for biota measurements.
Regional datasets concerning contaminants are automatically harvested and the resulting collections are harmonised and validated using ODV Software and following a common methodology for all sea regions ( https://doi.org/10.6092/8b52e8d7-dc92-4305-9337-7634a5cae3f4). Parameter names are based on P01 vocabulary, which relates to BODC Parameter Usage Vocabulary and is available at: https://vocab.nerc.ac.uk/search_nvs/P01/.
The harmonised dataset can be downloaded as as an ODV spreadsheet, which is composed of a metadata header followed by tab separated values. This spreadsheet can be imported into ODV Software for visualisation (more information can be found at: https://www.seadatanet.org/Software/ODV). In addition, the same dataset is offered also as a txt file in a long/vertical format, in which each P01 measurement is a record line. Additionally, there are a series of columns that split P01 terms into subcomponents (substance, CAS number, matrix...).This transposed format is more adapted to worksheet applications (e.g. LibreOffice Calc).
