High ventilation breathwork practices: An overview of their effects, mechanisms, and considerations for clinical applications. Neurosci Biobehav Rev 2023; 155:105453. [PMID: 37923236 DOI: 10.1016/j.neubiorev.2023.105453] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/19/2023] [Accepted: 10/30/2023] [Indexed: 11/07/2023]
Abstract
High Ventilation Breathwork (HVB) refers to practices employing specific volitional manipulation of breathing, with a long history of use to relieve various forms of psychological distress. This paper seeks to offer a consolidative insight into potential clinical application of HVB as a treatment of psychiatric disorders. We thus review the characteristic phenomenological and neurophysiological effects of these practices to inform their mechanism of therapeutic action, safety profiles and future clinical applications. Clinical observations and data from neurophysiological studies indicate that HVB is associated with extraordinary changes in subjective experience, as well as with profound effects on central and autonomic nervous systems functions through modulation of neurometabolic parameters and interoceptive sensory systems. This growing evidence base may guide how the phenomenological effects of HVB can be understood, and potentially harnessed in the context of such volitional perturbation of psychophysiological state. Reports of putative beneficial effects for trauma-related, affective, and somatic disorders invite further research to obtain detailed mechanistic knowledge, and rigorous clinical testing of these potential therapeutic uses.

Training during the COVID-19 pandemic: the experience of public health registrars in the London and Kent, Surrey, Sussex training programme. J Public Health (Oxf) 2023; 45:529-534. [PMID: 37326349 DOI: 10.1093/pubmed/fdac130] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 09/29/2022] [Indexed: 12/30/2023] Open
Abstract
BACKGROUND Public Health registrars (SpRs) were an important component of the workforce that contributed to the COVID-19 response. This study explores their contribution and the impact the early stages of the pandemic had on their learning and training. METHODS Data were collected from SpRs in the London and Kent, Surrey, Sussex training programme between July and September 2020 through a mixture of questionnaires and semi-structured interviews. A thematic analysis of interview transcripts was undertaken to identify themes. RESULTS 35/128 SpRs responded to the survey and 11 were interviewed. SpRs were placed across a range of organizations and made a significant contribution to the COVID-19 response. Overall, SpRs learned important skills but working on the response may for some have impacted negatively on training. A number of facilitators and barriers to learning were identified. CONCLUSION The study findings highlight the opportunities for learning created by the pandemic. However, changing projects and the desire of SpRs to contribute to the response meant the impacts on training were mixed. Future deployment of SpRs should consider the balance of responsibility and pace when delegating work, as well as the need to supervise effectively and support remote working to maintain good mental wellbeing.

Exploring postgraduate epidemiology competencies: Preparing our students for a post-COVID world. Aust N Z J Public Health 2023; 47:100026. [PMID: 36906998 DOI: 10.1016/j.anzjph.2023.100026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 11/08/2022] [Accepted: 12/11/2022] [Indexed: 03/12/2023] Open
Abstract
OBJECTIVE This research sought consensus from both experts and graduates on postgraduate epidemiology competencies. METHODS In 2021, a two-round online survey using a modified Delphi method was undertaken exploring competencies across six domains. Focus groups were conducted with recent postgraduate epidemiology graduates to assess their viewpoints on learning experiences and employability. RESULTS Forty-one experts participated in the first Delphi round. Nineteen factors reached consensus (>70% agreement) for importance and feasibility after two survey rounds in the following domains: general epidemiologic methods/concepts (n=8/13), advanced analytic/statistical skills (n=2/7), applied epidemiology/specialised fields (n=1/4), professional/transferrable skills (n=5/14), general public health knowledge/skills (n=2/4), independent research and work-integrated learning (n=1/3). Nine graduates participated in focus groups. A main theme was the substantial value gained in undertaking a dissertation, acknowledging its benefit for applying research skills and for networking opportunities. CONCLUSIONS To ensure that high-quality epidemiological research and practice continues, we need consensus on the set of essential skills required of graduating students. IMPLICATIONS FOR PUBLIC HEALTH Competencies for postgraduate epidemiology students require periodic review to safeguard a workforce that can meet emerging challenges and work across academia, research, policy, and practice.

Abstract
BACKGROUND Health services implemented a range of initiatives during the COVID-19 pandemic to support employee wellbeing and assist employees to manage the professional and personal challenges they experienced. However, it is not known if such initiatives were acceptable to employees or met their needs. AIMS To evaluate the wellbeing and support initiatives implemented at an Australian health service during the COVID-19 pandemic from the perspectives of employees (both users and non-users) and key stakeholders. METHODS A mixed-methods design (survey, interviews and data audit) to investigate employees' and key stakeholders' perceptions, experiences and use of the wellbeing and support initiatives implemented at a large tertiary metropolitan health service in Melbourne, Australia. RESULTS Ten employees participated in an interview and 907 completed a survey. The initiatives were well used and appreciated by staff. There was no significant difference in the proportion of clinical staff who had used the initiatives compared to non-clinical staff (44% versus 39%; P=0.223). Survey respondents reported the initiatives improved their mental health (n = 223, 8%), ability to cope with COVID-19 related stress and anxiety (n = 206, 79%), do their work (n = 200, 77%) and relationships with colleagues (n = 174, 67%). Staff would like many of the initiatives (with some modifications) to continue after the COVID-19 pandemic. CONCLUSIONS The findings suggest a high level of staff satisfaction with the implemented wellbeing and support initiatives, and confirm the need for, and importance of, developing and implementing initiatives to support health service staff during outbreaks of infectious diseases such as the COVID-19 pandemic.

Abstract
Abstract
In 2020 the Dutch National Institute for Public Health and the Environment (RIVM) published its vision on climate change and health. This vision reflects the position of RIVM in society and highlights the transdisciplinary and collaborative nature of our work on this topic. We define this societal challenge as: protecting and promoting the health of people throughout society with regard to climate change and climate measures. The purpose of our work on this challenge is to support all levels of Dutch government with policy development and implementation and to forge links with both national and international organisations to further knowledge and expertise.
The focus of our work, in collaboration with the aforementioned actors, is as follows:
1. Knowledge translation of the health impacts of climate change for the public and government.
2. Developing instruments to promote health in relation to climate change and mitigation and adaptation measures.
3. Implementation research on solutions to mitigate and adapt to climate change.
4. Strengthening national and international cooperation to enhance synergies in our work.
In the workshop we will present examples of our work:
• Quantifying the health impacts of climate change, now and in the future under different global warming scenarios.
• Developing a set of indicators to monitor the health impacts of climate change and mitigation and adaptation plans and actions.
• Collating and disseminating easily digestible information for public health services on evidence-based, effective adaptation measures.
• Developing tools and instruments to ensure health benefits and limit unintended consequences of adaptation measures, such as green and blue spaces.
• Prioritising research on climate change and health through a research agenda.
Workshop participants will be encouraged to provide feedback to inform RIVM's future work and that of other national public health institutes, and to ensure we are fully supporting our stakeholders.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study. THE LANCET. RESPIRATORY MEDICINE 2022; 10:761-775. [PMID: 35472304 PMCID: PMC9034855 DOI: 10.1016/s2213-2600(22)00127-8] [Citation(s) in RCA: 144] [Impact Index Per Article: 72.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/23/2022] [Accepted: 03/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
Introduction It is a common patient perception that their discharge from hospital is delayed by waiting for medicines (1). However, it is important to consider the entire discharge process when addressing this problem (2). In our large tertiary referral hospital, clinical pharmacy services were moved from wards to the dispensary following a staffing crisis during 2018. Ward-based services were reintroduced in 2020, but doubts remained over the practicality and benefits of doing this. Aim To compare the efficiency of ward and dispensary based clinical pharmacy services in our hospital in terms of interventions made and time taken. Methods We completed an observational service evaluation. Data on the time taken to process discharge medication requests with the dispensary-based service were collected retrospectively from the hospital electronic discharge system for 12 months (2018) for five medical wards. Equivalent data for the ward-based service were collected prospectively over three days (2020) by pharmacists delivering the service to seven medical wards, as this was considered more accurate, and several process steps did not exist in the ward-based model. For example, prescriber sending request to pharmacy and pharmacy acknowledging receipt of a request. The prospective data collection period was curtailed by Covid-19. Descriptive statistics were produced using Excel. Results Using the dispensary-based service (2018), 4459 medicine requests were processed from 5 medical wards, during a 12-month period. The mean time between prescribing and reaching the screening pharmacist was 175 minutes [95%CI ± 25.4]. It took an estimated time of 62 minutes [95%CI ± 2.99] to screen and resolve an intervention, with a mean of 3 interventions/ward/day. In 2020, using the ward-based approach to clinical pharmacy which screened medicine requests on the ward, 142 requests were screened over three days from seven wards, with no delay between prescribing and clinical screening. It took a mean of 17 minutes [95%CI ± 10.63] to screen and resolve an intervention, with a mean of 15 interventions/ward/day. Conclusion Ward based pharmacy yielded five times more interventions, took an average of 45 minutes less to screen and resolve issues per request and removed 175 minutes of process time. The additional time required to resolve issues identified in the dispensary-based screening process was thought to be the delay in contacting either the appropriate member of the ward staff referencing a particular patient for information or identifying and contacting the prescriber, or a combination of both. This study is limited by the long delay between data collection periods and the small sample size in 2020, but the differences between the two systems were large and there had been few other changes to hospital systems. Other limitations include changes related to Covid-19 and the lack of a control group, so it is not possible to establish a causal relationship between the type of pharmacy service and study outcomes.

Abstract
INTRODUCTION Objective Structured Clinical Examinations (OSCE) are used to assess clinical skills. We investigated how exit OSCEs changed in Australian medical schools in response to the COVID-19 pandemic. MATERIALS AND METHODS The lead ACCLAiM assessment academic from 12 eligible Australian medical school members of the Australian Collaboration for Clinical Assessment in Medicine (ACCLAiM) received a 45-item semi-structured online questionnaire. RESULTS All schools (12/12) responded. Exit OSCEs were not used by one school in 2019, and 3/11 schools in 2020. Of eight remaining schools, four reduced station numbers and testing time. The minimum OSCE testing time decreased from 64 min in 2019 to 54 min in 2020. Other modifications included: a completely online 'e-OSCE' (n = 1); hybrid delivery (n = 4); stations using: videos of patient encounters (n = 3), telephone calls (n = 2), skill completion without face-to-face patient encounters (n = 3). The proportion of stations involving physical examination reduced from 33% to 17%. Fewer examiners were required, and university faculty staff formed a higher proportion of examiners. CONCLUSIONS All schools changed their OSCEs in 2020 in response to COVID-19. Modifications varied from reducing station numbers and changing delivery methods to removing OSCE and complete assessment re-structuring. Several innovative methods of OSCE delivery were implemented to preserve OSCE validity and reliability whilst balancing feasibility.

Abstract
Abstract
Introduction
Hepaticojejunostomy (HJ) is the standard repair following major bile duct injury (BDI), but anastomotic stricture can result in long-term morbidity. There is a need to assimilate high-level evidence to establish risk factors for the development of anastomotic stricture after HJ for BDI.
Method
A systematic review of studies reporting the rate of anastomotic stricture after HJ for BDI was performed according to PRISMA guidelines. Meta-analyses of proposed risk factors were then performed.
Results
Meta-analysis included five factors (n = 2,198 patients, 17 studies). Vascular injury (OR 2.71; 95%CI 1.37-5.35; p = 0.004), postoperative bile leak (OR: 8.03; 95%CI 2.04-31.71; p = 0.003), previous repair (OR: 5.36; 95%CI 1.04-27.76;p=0.05) and repair by non-specialist surgeon (OR 11.29; 95%CI 5.21-24.47; p < 0.0001) were associated with HJ stricture after BDI. Strasberg injury grade was not associated with HJ stricture (OR: 1.05; 95%CI 0.63-1.75; p = 0.86). Due to heterogeneity of reporting it was not possible to perform meta-analysis for impact of timing of repair on anastomotic stricture rate.
Conclusions
This meta-analysis identifies factors that significantly increase the rate of anastomotic stricture after HJ for BDI. Knowledge of these risk factors will allow risk stratification in terms of follow-up for individual cases, better informed consent, and guidance for medico-legal cases.

Longitudinal associations between exposure to anesthesia and neurocognitive functioning in pediatric medulloblastoma. Eur J Cancer 2021; 148:103-111.

Abstract
AIM To examine whether anesthesia exposure is associated with neurocognitive decline in pediatric medulloblastoma. METHODS Patients were treated at St. Jude Children's Research Hospital and completed ≥2 protocol-directed neurocognitive assessments (n = 107) as part of a multisite clinical trial for pediatric medulloblastoma (NCT00085202). Patients received risk-adapted craniospinal photon irradiation, followed by four cycles of high-dose chemotherapy and stem cell rescue. Neurocognitive testing was completed at study baseline (after surgery and <2 weeks of starting radiation therapy) and annually for 5 years. Data on anesthesia exposure during treatment was abstracted from medical records. RESULTS Patients were 10.2 years at diagnosis on average (SD = 4.5; 37% female, 73% average-risk). Mean cumulative anesthesia duration was 20.4 h (SD = 15.2; range 0.7-55.6 h). In the overall group, longer anesthesia duration was associated with greater declines in IQ (Estimate = -0.08, P < 0.001), attention (Estimate = -0.10, P < .001) and processing speed (Estimate = -0.13, P < 0.001). Similar results were shown in subgroups of patients who were <7 years at diagnosis (IQ = -0.14, P = 0.027; Attention = -0.25: P = 0.011), ≥7 years at diagnosis (Attention = -0.07, P = 0.039; Processing Speed = -0.08, P = 0.022), treated for high-risk disease (IQ = -0.09, P = 0.024; Attention = -0.11, P = 0.034; Processing Speed = -0.13, P = 0.001), or treated for average-risk disease (IQ = -0.05, P = .022; Attention = -0.08, P = 0.011; Processing Speed = -0.10, P < 0.001). CONCLUSION Greater anesthesia exposure is a risk factor for clinically significant neurocognitive decline, in addition to factors of age at diagnosis and treatment risk arm. This result is notable as there are evidence-based strategies that can limit the need for anesthesia. Limiting anesthesia exposure, as feasible, may mitigate neurocognitive late effects, and thus, improve quality of life for survivors.

Feed acidification and steam-conditioning temperature influence nutrient utilization in broiler chickens fed wheat-based diets. Poult Sci 2020; 99:5037-5046. [PMID: 32988540 PMCID: PMC7598303 DOI: 10.1016/j.psj.2020.06.056] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 06/07/2020] [Accepted: 06/20/2020] [Indexed: 12/28/2022] Open
Abstract
Two experiments were conducted to examine the effects of conditioning temperature (CT) and the interactive influence of feed acidification (FA) and CT on the performance, coefficient of apparent ileal digestibility (CAID) of nitrogen (N), starch, fat calcium (Ca) and phosphorus (P), and AME in broilers. In both experiments, each treatment was randomly allocated to 6 cages (8 birds per cage) and fed from 1 to 21 D posthatch. In experiment 1, the effect of CT was evaluated using a wheat-based diet at 3 CT: unconditioned, conditioned at 60°C or 90°C. All the diets by-passed the pellet press and collected in mash form. Birds fed the diet conditioned at 90°C consumed more (P < 0.05) feed and tended (P = 0.087) to have higher feed per gain (F:G) than those fed the unconditioned diet but similar to those fed the diet conditioned at 60°C. A tendency was noted for CT to affect the CAID of N (P = 0.071) and starch (P = 0.093), with reduced digestibility values in the diet conditioned at 90°C. Conditioning at 90°C resulted in lower (P < 0.05) AME. In experiment 2, three inclusions of an acidifier (0.0, 7.0, and 10 g/kg) and 2 CT of 60°C and 90°C were evaluated in a 3 × 2 factorial arrangement of treatments using pelleted diets. Neither the main effects nor the interaction between acidifier addition and CT was significant for weight gain, feed intake, and F:G. The FA increased (P < 0.05) the CAID of N, fat, and P at both inclusion levels and of starch at 10 g/kg. Conditioning at 90°C reduced (P < 0.05) the CAID of starch, fat, and Ca, regardless of FA level. Overall, the present data showed that the application of high CT for broiler feed manufacture can impair nutrient utilization and, consequently the feed efficiency in broilers. Feed acidification imparts some benefits to nutrient digestibility in broilers fed pelleted wheat-based diets.

Experiences of using the i-PARIHS framework: a co-designed case study of four multi-site implementation projects. BMC Health Serv Res 2020; 20:573. [PMID: 32576197 PMCID: PMC7310499 DOI: 10.1186/s12913-020-05354-8] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 05/24/2020] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND The integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework is an implementation framework that has been developed and refined over the last 20 years. Its underlying philosophy is that implementing research into healthcare practice is complex, unpredictable and non-linear which therefore requires a flexible and responsive approach to implementation. Facilitation is recognized as the central ingredient of this approach, and i-PARIHS now provides a Facilitation Guide with associated tools. This multiple case study of four implementation projects explored how the i-PARIHS framework has been practically operationalized by diverse implementation project teams. METHODS A co-design approach was used to elicit the experiences of four implementation project teams who used the i-PARIHS framework to guide their implementation approach. We conducted the established co-design steps of (i) setting up for success, (ii) gathering the experience, and (iii) understanding the experience. In particular we explored teams' approaches to setting up their projects; why and how they used the i-PARIHS framework and what they learnt from the experience. RESULTS We found both commonalities and differences in the use of i-PARIHS across the four implementation projects: (i) all the projects used the Facilitation Checklist that accompanies i-PARIHS as a starting point, (ii) the projects differed in how facilitation was carried out, (iii) existing tools were adapted for distinct phases: pre-implementation, during implementation, and post-implementation stages; and (iv) project-specific tools were often developed for monitoring implementation activities and fidelity. CONCLUSIONS We have provided a detailed overview of how current users of i-PARIHS are operationalising the framework, which existing tools they are using or adapting to use, and where they have needed to develop new tools to best utilise the framework. Importantly, this study highlights the value of existing tools from the published i-PARIHS Facilitation Guide and provides a starting point to further refine and add to these tools within a future Mobilising Implementation of i-PARIHS (or "Mi-PARIHS") suite of resources. Specifically, Mi-PARIHS might include more explicit guidance and/or tools for developing a structured implementation plan and monitoring fidelity to the implementation plan, including recording how strategies are tailored to an evolving context.

Abstract
BACKGROUND Schizophrenia is a highly heritable disorder, linked to several structural abnormalities of the brain. More specifically, previous findings have suggested that increased gyrification in frontal and temporal regions are implicated in the pathogenesis of schizophrenia. METHODS The current study included participants at high familial risk of schizophrenia who remained well (n = 31), who developed sub-diagnostic symptoms (n = 28) and who developed schizophrenia (n = 9) as well as healthy controls (HC) (n = 16). We first tested whether individuals at high familial risk of schizophrenia carried an increased burden of trait-associated alleles using polygenic risk score analysis. We then assessed the extent to which polygenic risk was associated with gyral folding in the frontal and temporal lobes. RESULTS We found that individuals at high familial risk of schizophrenia who developed schizophrenia carried a significantly greater burden of risk-conferring variants for the disorder compared to those at high risk (HR) who developed sub-diagnostic symptoms or remained well and HC. Furthermore, within the HR cohort, there was a significant and positive association between schizophrenia polygenic risk score and bilateral frontal gyrification. CONCLUSIONS These results suggest that polygenic risk for schizophrenia impacts upon early neurodevelopment to confer greater gyral folding in adulthood and an increased risk of developing the disorder.

Abstract
Radiomics describes a broad set of computational methods that extract quantitative features from radiographic images. The resulting features can be used to inform imaging diagnosis, prognosis, and therapy response in oncology. However, major challenges remain for methodologic developments to optimize feature extraction and provide rapid information flow in clinical settings. Equally important, to be clinically useful, predictive radiomic properties must be clearly linked to meaningful biologic characteristics and qualitative imaging properties familiar to radiologists. Here we use a cross-disciplinary approach to highlight studies in radiomics. We review brain tumor radiologic studies (eg, imaging interpretation) through computational models (eg, computer vision and machine learning) that provide novel clinical insights. We outline current quantitative image feature extraction and prediction strategies with different levels of available clinical classes for supporting clinical decision-making. We further discuss machine-learning challenges and data opportunities to advance radiomic studies.

Abstract
This study compares a recently introduced latex agglutination test for the serogrouping of beta-haemolytic streptococci against four internationally used commercial kits. The new kit is Prolex-Blue (Pro-Lab Diagnostics) and the comparators are Streptex (Murex), PathoDx (DPC), Streptococcus Grouping kit (Oxoid) and Prolex-White (Pro-Lab Diagnostics). A total of 302 consecutive clinical isolates are tested against all five kits, following the individual manufacturer's protocol, for both accuracy and speed. In addition, the data produced permits determination of the strengths or weaknesses of the kits against individual serotypes. Prolex-Blue proved to be both accurate and rapid, with a sensitivity of 99% and a specificity of 100%. Furthermore, average time to agglutination was substantially less than achieved by three of the other four kits evaluated.

MaxiK channel interactome reveals its interaction with GABA transporter 3 and heat shock protein 60 in the mammalian brain. Neuroscience 2016; 317:76-107.

Abstract
Large conductance voltage and calcium-activated potassium (MaxiK) channels are activated by membrane depolarization and elevated cytosolic Ca(2+). In the brain, they localize to neurons and astrocytes, where they play roles such as resetting the membrane potential during an action potential, neurotransmitter release, and neurovascular coupling. MaxiK channels are known to associate with several modulatory proteins and accessory subunits, and each of these interactions can have distinct physiological consequences. To uncover new players in MaxiK channel brain physiology, we applied a directed proteomic approach and obtained MaxiK channel pore-forming α subunit brain interactome using specific antibodies. Controls included immunoprecipitations with rabbit immunoglobulin G (IgG) and with anti-MaxiK antibodies in wild type and MaxiK channel knockout mice (Kcnma1(-/-)), respectively. We have found known and unreported interactive partners that localize to the plasma membrane, extracellular space, cytosol and intracellular organelles including mitochondria, nucleus, endoplasmic reticulum and Golgi apparatus. Localization of MaxiK channel to mitochondria was further confirmed using purified brain mitochondria colabeled with MitoTracker. Independent proof of MaxiK channel interaction with previously unidentified partners is given for GABA transporter 3 (GAT3) and heat shock protein 60 (HSP60). In human embryonic kidney 293 cells containing SV40 T-antigen (HEK293T) cells, both GAT3 and HSP60 coimmunoprecipitated and colocalized with MaxiK channel; colabeling was observed mainly at the cell periphery with GAT3 and intracellularly with HSP60 with protein proximity indices of ∼ 0.6 and ∼ 0.4, respectively. In rat primary hippocampal neurons, colocalization index was identical for GAT3 (∼ 0.6) and slightly higher for HSP60 (∼ 0.5) association with MaxiK channel. The results of this study provide a complete interactome of MaxiK channel the mouse brain, further establish the localization of MaxiK channel in the mouse brain mitochondria and demonstrate the interaction of MaxiK channel with GAT3 and HSP60 in neurons. The interaction of MaxiK channel with GAT3 opens the possibility of a role of MaxiK channel in GABA homeostasis and signaling.

Abstract
BACKGROUND Oxidative stress with dysregulated inflammation are hallmarks of sepsis. Zinc and selenium have important antioxidant functions, such that they could be important in patients with sepsis. We used an in vitro approach to assess the effect of zinc and selenium on oxidative stress, mitochondrial function, and inflammatory responses in conditions mimicking sepsis and related the findings to plasma concentrations and biomarkers in patients with and without sepsis. METHODS Human endothelial cells were exposed to a range of zinc and selenium concentrations in conditions mimicking sepsis. Zinc, selenium, and a series of biomarkers of oxidative stress and inflammation were measured in plasma from critically ill patients with and without sepsis. RESULTS Culturing cells with different concentrations of zinc caused altered zinc transporter protein expression and cellular zinc content, and selenium affected glutathione peroxidase 3 activity. Although zinc or selenium at physiological concentrations had no effect on interleukin-6 release in vitro, higher concentrations of the trace elements were associated with improved mitochondrial function. Plasma zinc and selenium concentrations were low in patients [zinc: median (range) 4.6 (2.1-6.5) μM in control patients without sepsis and 3.1 (1.5-5.4) μM in patients with sepsis, P=0.002; and selenium: 0.78 (0.19-1.32) μM in control patients and 0.42 (0.22-0.91) μM in sepsis patients, P=0.0009]. Plasma concentrations of interleukin-6, other biomarkers of inflammation, and markers of oxidative damage to proteins and lipids were elevated, particularly in patients with sepsis, and were inversely related to plasma zinc and selenium concentrations. CONCLUSIONS Zinc and selenium concentrations were reduced in critically ill patients, with increased oxidative stress and inflammatory biomarkers, particularly in patients with sepsis. Oxidative stress as a result of suboptimal selenium and zinc concentrations might contribute to damage of key proteins.

Abstract
Trying to remember something now typically improves your ability to remember it later. However, after watching a video of a simulated bank robbery, participants who verbally described the robber were 25% worse at identifying the robber in a lineup than were participants who instead listed U.S. states and capitals-this has been termed the "verbal overshadowing" effect (Schooler & Engstler-Schooler, 1990). More recent studies suggested that this effect might be substantially smaller than first reported. Given uncertainty about the effect size, the influence of this finding in the memory literature, and its practical importance for police procedures, we conducted two collections of preregistered direct replications (RRR1 and RRR2) that differed only in the order of the description task and a filler task. In RRR1, when the description task immediately followed the robbery, participants who provided a description were 4% less likely to select the robber than were those in the control condition. In RRR2, when the description was delayed by 20 min, they were 16% less likely to select the robber. These findings reveal a robust verbal overshadowing effect that is strongly influenced by the relative timing of the tasks. The discussion considers further implications of these replications for our understanding of verbal overshadowing.

Abstract
The Newcastle upon Tyne Hospitals NHS Foundation Trust (NuTH) implemented a seek and destroy (S&D) programme in 2006 to minimise meticillin-resistant Staphylococcus aureus (MRSA) colonisation and/or infection of patients. Using a phased introduction, all patient specialties were included in the scheme by September 2008, well in advance of the mandatory Department of Health, England (DoH) requirement for all patients to be screened. NuTH screens nose, throat and perineum samples from approximately 15,000 patients per month using a chromogenic culture method, showing a mean MRSA prevalence of 2.4%. Provision of seven-day microbiology and infection control services ensured that the turnaround time to prescribing decolonisation therapy was <24 h. Analysis of 168,073 results identified the necessity for inclusion of all three screening sites to maximise recovery of MRSA. Appraisal of the S&D policy demonstrated that MRSA detection rates did not increase despite an exponential increase in workload owing to mandatory inclusion of low risk areas in the screening programme. Review of data during a typical one-month period indicated that only seven day-case patients would not have been identified as MRSA carriers using our targeted S&D approach compared with the DoH universal screening. Detection of these additional patients incurred total laboratory costs of £20,000 and generated a further 4200 associated negative screens in one month alone. Our study indicates that a screening strategy based upon clinical risk is more pragmatic and more cost-effective than the universal programme currently required in England.
