Abstract
While a large proportion of the population in Papua New Guinea (PNG) maintain a subsistence lifestyle, exposure to modernisation and industrialisation since European contact has influenced a transition towards Western diets. This review aimed to scope and summarise the published research on dietary intake among Pacific Islander adults in PNG. Four electronic databases and grey literature were searched. Two reviewers completed the screening and data extraction. Fourteen studies were included from the Highlands (n = 7), Southern (n = 5), Momase (n = 1) and both the Highlands/Southern region (n = 1). No studies were from the Islands region. The majority of the studies were published prior to the year 2000 (n = 9). Geographical region and degree of urbanisation had an impact on dietary intake. Urban areas reported higher intakes of energy, protein and fat compared to rural areas. In the Southern region, a variety of foods, including sago, taro, kaukau, cooked banana, coconut and cassava contributed to energy intake, while kaukau was the main energy and protein source in the Highlands. The main foods contributing to protein in the Southern region were fresh fish, land animals and purchased animals. This review highlights an evidence gap regarding dietary intake research. Within the context of international initiatives, there is an urgent call for research aimed at understanding the social and cultural contextualisation of dietary behaviours in PNG.

Abstract
BACKGROUND & AIMS Clostridioides difficile is a toxin-secreting bacteria that is an urgent antimicrobial resistance threat, with approximately 25% of patients developing recurrent infections. Inflammatory bowel disease (IBD) patients are at increased risk of severe, recurrent C. difficile infection. METHODS To investigate a role for C. difficile infection in IBD pathogenesis, we collected peripheral blood and stool from 20 each of ulcerative colitis patients, Crohn's disease patients, and healthy control subjects. We used a flow cytometric activation induced marker assay to quantify C. difficile toxin-specific CD4+ T cells and 16S ribosomal RNA sequencing to study microbiome diversity. RESULTS We found IBD patients had significantly increased levels of C. difficile toxin B-specific CD4+ T cells, but not immunoglobulin G or immunoglobulin A, compared with healthy control subjects. Within antigen-specific CD4+ T cells, T helper type 17 cells and cells expressing the gut homing receptor integrin β7 were reduced compared with healthy control subjects, similar to our previous study of non-IBD patients with recurrent C. difficile infection. Stool microbiome analysis revealed that gut homing, toxin-specific CD4+ T cells negatively associated with microbial diversity and, along with T helper type 17 cells, positively associated with bacteria enriched in healthy control subjects. CONCLUSIONS These data suggest that IBD patients, potentially due to underlying intestinal dysbiosis, experience undiagnosed C. difficile infections that result in impaired toxin-specific immunity. This may contribute to the development of inflammatory T cell responses toward commensal bacteria and provide a rationale for C. difficile testing in IBD patients.

Abstract
Matching the language or content of a message to the psychological profile of its recipient (known as "personalized persuasion") is widely considered to be one of the most effective messaging strategies. We demonstrate that the rapid advances in large language models (LLMs), like ChatGPT, could accelerate this influence by making personalized persuasion scalable. Across four studies (consisting of seven sub-studies; total N = 1788), we show that personalized messages crafted by ChatGPT exhibit significantly more influence than non-personalized messages. This was true across different domains of persuasion (e.g., marketing of consumer products, political appeals for climate action), psychological profiles (e.g., personality traits, political ideology, moral foundations), and when only providing the LLM with a single, short prompt naming or describing the targeted psychological dimension. Thus, our findings are among the first to demonstrate the potential for LLMs to automate, and thereby scale, the use of personalized persuasion in ways that enhance its effectiveness and efficiency. We discuss the implications for researchers, practitioners, and the general public.

Abstract
BACKGROUND While acknowledgement of emotions' importance in simulation-based education is emerging, there are concerns regarding how education researchers understand the concept of emotions for them to deliberately incorporate emotionally charged scenarios into simulation-based education. This concern is highlighted especially in the context of medical education often lacking strong theoretical integration. To map out how current simulation-based education literature conceptualises emotion, we conducted a scoping review on how emotions and closely related constructs (e.g. stress, and emotional intelligence) are conceptualised in simulation-based education articles that feature medical students, residents, and fellows. METHODS The scoping review was based on articles published in the last decade identified through database searches (EMBASE and Medline) and hand-searched articles. Data extraction included the constructs featured in the articles, their definitions, instruments used, and the types of emotions captured. Only empirical articles were included (e.g. no review or opinion articles). Data were charted via descriptive analyses. RESULTS A total of 141 articles were reviewed. Stress was featured in 88 of the articles, while emotions and emotional intelligence were highlighted in 45 and 34 articles respectively. Conceptualisations of emotions lacked integration of theory. Measurements of emotions mostly relied on self-reports while stress was often measured via physiological and self-report measurements. Negative emotions such as anxiety were sometimes seen as interchangeable with the term stress. No inferences were made about specific emotions of participants from their emotional intelligence. CONCLUSIONS Our scoping review illustrates that learners in simulation-based education are most often anxious and fearful. However, this is partially due to medical education prioritising measuring negative emotions. Further theoretical integration when examining emotions and stress may help broaden the scope towards other kinds of emotions and better conceptualisations of their impact. We call for simulation education researchers to reflect on how they understand emotions, and whether their understanding may neglect any specific aspect of affective experiences their simulation participants may have.

Abstract
BACKGROUND For exercise interventions to be effectively reproduced or applied in a "real world" clinical setting, clinical trials must thoroughly document all components of the exercise prescription and ensure that participants adhere to each component. However, previous reviews have not critically examined the quality of exercise prescription of inpatient Pulmonary Rehabilitation (PR) programs. OBJECTIVE The objectives of this review were to evaluate the (a) application of the principles of exercise training, (b) reporting of the frequency, intensity, time and type (FITT) components of exercise prescription, and (c) reporting of patient's adherence to the FITT components in intervention studies for patients admitted to hospital for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS Relevant scientific databases were searched for randomized controlled trials (RCTs) that compared in-hospital PR with usual care for people hospitalized with AECOPD. Title and abstract followed by full-text screening were conducted independently by two reviewers. Data were extracted and synthesized to evaluate the application of the principles of exercise training and the reporting/adherence of the FITT components. RESULTS Twenty-seven RCTs were included. Only two applied all principles of exercise training. Specificity was applied by 70%, progression by 48%, overload by 37%, initial values by 89% and diminishing returns and reversibility by 37% of trials. Ten trials adequately reported all FITT components. Frequency and type were the components most reported (85% and 81%, respectively), while intensity was less frequently reported (52%). Only three trials reported on the patient's adherence to all four components. CONCLUSIONS Studies have not adequately reported the exercise prescription in accordance with the principles of exercise training nor reported all the FITT components of the exercise prescription and patient's adherence to them. Therefore, interpretation of the current literature is limited and information for developing exercise prescriptions to individuals hospitalized with an AECOPD is lacking.

Abstract
Zusammenfassung
Gegenstand und Ziel Ziel der Studie war es, Daten über den Einsatz von Antibiotika (AB) bei Hunden und Katzen in Tierarztpraxen und -kliniken in Bayern zu erheben. Dabei sollte evaluiert werden, ob sich Änderungen hinsichtlich des Antibiotikaeinsatzes nach Novellierung der Verordnung über Tierärztliche Hausapotheken (TÄHAV) im März 2018 ergeben haben.
Material und Methoden Mittels zweier anonymisierter Online-Umfragen wurden 2017 und 2020 Tierärzte/-innen (TÄ) in Bayern, zu deren Patienten Hunde und Katzen zählen, zur Anwendung von AB sowie zur Einschätzung der Resistenzsituation befragt. Die Ergebnisse der beiden Umfragen wurden anschließend miteinander verglichen.
Ergebnisse Für 2017 konnten 238 Fragebögen ausgewertet werden; 2020 waren es 160. Die 3 am häufigsten zur systemischen Therapie beim Kleintier angewendeten AB waren 2017 Amoxicillin/Clavulansäure (74,8 % der TÄ), Enrofloxacin (56,7 %) und Amoxicillin (53,4 %). 2020 wurden Amoxicillin/Clavulansäure (88,8 %), Amoxicillin (67,5 %) und Metronidazol (33,8 %) genannt. Die teilnehmenden TÄ gaben an, signifikant weniger Cephalosporine der 3. und 4. Generation (von 20,2 % der teilnehmenden TÄ in 2017 auf 9,4 % in 2020, p = 0,005) und Fluorchinolone (von 80,3 % auf 33,1 %, p < 0,001) einzusetzen. Die Wahl eines AB wurde 2020 bei 83,8 % der befragten TÄ durch rechtliche Vorgaben beeinflusst; weitere Einflussfaktoren waren Verträglichkeit (81,3 %), Applikationsart (76,9 %), Akzeptanz durch den Patienten (70,0 %) und Häufigkeit der Anwendung (64,4 %), wobei letzterer von TÄ aus der Praxis (83,8 %, p = 0,004) signifikant häufiger genannt wurden als von TÄ aus Kliniken.
Schlussfolgerung Im Vergleich zu 2017 gaben TÄ 2020 einen signifikant geringeren Einsatz von Fluorchinolonen und Cephalosporinen der 3. und 4. Generation bei Hund und Katze an. Diese Änderungen im Verschreibungsverhalten könnten Folgen der Novellierung der TÄHAV sein, die ein Umwidmungsverbot sowie eine Antibiogrammpflicht dieser AB-Klassen vorgibt.
Klinische Relevanz Rechtliche Vorgaben können möglicherweise einen positiven Einfluss auf die Menge und Art der in der Kleintiermedizin eingesetzten Antibiotika haben und somit bei der Vermeidung von Antibiotikaresistenzen helfen.

Abstract
BACKGROUND Next generation sequencing studies have revealed an ever-increasing number of causes for genetic disorders of central nervous system white matter. A substantial number of disorders are identifiable from their specific pattern of biochemical and/or imaging findings for which single gene testing may be indicated. Beyond this group, the causes of genetic white matter disorders are unclear and a broader approach to genomic testing is recommended. AIM This study aimed to identify the genetic causes for a group of individuals with unclassified white matter disorders with suspected genetic aetiology and highlight the investigations required when the initial testing is non-diagnostic. METHODS Twenty-six individuals from 22 families with unclassified white matter disorders underwent deep phenotyping and genome sequencing performed on trio, or larger, family groups. Functional studies and transcriptomics were used to resolve variants of uncertain significance with potential clinical relevance. RESULTS Causative or candidate variants were identified in 15/22 (68.2%) families. Six of the 15 implicated genes had been previously associated with white matter disease (COL4A1, NDUFV1, SLC17A5, TUBB4A, BOLA3, DARS2). Patients with variants in the latter two presented with an atypical phenotype. The other nine genes had not been specifically associated with white matter disease at the time of diagnosis and included genes associated with monogenic syndromes, developmental disorders, and developmental and epileptic encephalopathies (STAG2, LSS, FIG4, GLS, PMPCA, SPTBN1, AGO2, SCN2A, SCN8A). Consequently, only 46% of the diagnoses would have been made via a current leukodystrophy gene panel test. DISCUSSION These results confirm the importance of broad genomic testing for patients with white matter disorders. The high diagnostic yield reflects the integration of deep phenotyping, whole genome sequencing, trio analysis, functional studies, and transcriptomic analyses. CONCLUSIONS Genetic white matter disorders are genetically and phenotypically heterogeneous. Deep phenotyping together with a range of genomic technologies underpin the identification of causes of unclassified white matter disease. A molecular diagnosis is essential for prognostication, appropriate management, and accurate reproductive counseling.

Abstract
Study question
What is the predictive value of the menstrual cycle pattern in adolescence on fertility, cardiovascular- and metabolic health at age 40 years
Summary answer
Adolescents with oligomenorrhea are more often treated to conceive, but, are as likely to have children as those with regular menstrual cycles.
What is known already
Polycystic ovary syndrome(PCOS) is the main endocrine disorder in women of reproductive age. Adolescents with oligomenorrhea have a high risk for PCOS and potential subfertility due to ovulatory disorders. PCOS is also associated with pregnancy complications as pregnancy induced hypertension, pre-eclampsia and gestational diabetes. Furthermore PCOS is related to long-term health risks such as cardiovascular disease and diabetes. Studies on longitudinal implications of adolescent oligomenorrhea for fertility are lacking. Data on long-term health consequences of PCOS usually describe the development of these diseases in adult PCOS patients and lack longitudinal input starting at adolescence.
Study design, size, duration
This is a long-term follow-up study based on a unique adolescent study on menstrual irregularities performed between 1990-1997, the Pubertal onset of Menstrual Cycle abnormalities, a prospective study, the POMP study. We contacted stratified samples of this studycohort two decades after the initial study for a questionnaire assessing PCOS features, fertility history, pregnancy outcome, metabolic and cardiovascular health.
Participants/materials, setting, methods
160 of 271 of the invited adult participants completed the questionnaire; the mean adolescent age was 15.3 years and the women were 39.6 years at time of follow-up. 92 had a regular menstrual cycle as adolescent and also as adult (REGREG); 15 changed to oligomenorrhea in adulthood (REGOL); 21 oligoamenorrheic adolescents remained oligomenorrheic (OLOL),and 31 oligomenorrheic girls developed a regular menstrual cycle pattern (OLREG).
Main results and the role of chance
Of those with adolescent regular menstrual cycles(REGREG+REGOL) 12 never tried to conceive, 4 tried but never conceived and 92 of 96(95,8%) conceived, 89 of 96(92,7%) delivered at least one living child. The mean time to pregnancy (TTP) in the REGREG subgroup was 7.2(SD 11.2) months with 14.6% subfertility (TTP > 12 months) compared to a TTP of 14.9 (SD 19.5) months with 35.7% subfertility in the REGOLsubgroup. 47 of 52 adolescents with oligomenorrhea (OLOL+OLREG) tried to conceive and 45(95,6%) succeeded to have at least one full term pregnancy. The mean TTP was 12.8 months (SD 19.8) in the OLOL subgroup versus 13.6 (SD 18.2) months in the OLREG subgoup, respectively 30 % and 24 % had a TTP > 12 months (p = 0.17). The median number of children was two in all subgroups. The OLOL subgroup had more fertility treatments -40%- than the other subgroups (14-22%) (p = 0.08). BMI did not differ between the four subgroups. The risk for pregnancy induced hypertension or pre-eclampsia was comparable among all subgroups (14-20%). Gestational diabetes developed in 3 participants all part of the OLOLsubgroup. Adult diabetes (0-5%), hypertension(3-10%), hypercholesterolaemia(0-5%) were diagnosed most frequently in the OLOLsubgroup, Cardiovascular disease(0-1%) in the REGREG subgroup
Limitations, reasons for caution
The numbers in the study are small. However the small difference between the percentage with a least one living child of those with adolescent oligomenorhea versus those with adolescent regular menstrual cycles is reassuring. Time to pregnancy data may have been biased by early treatment of oligomenorrheic adults.
Wider implications of the findings
Oligomenorrheic adolescents may be reassured for their chance to have a live birth being comparable with those with a regular menstrual cycle.

Abstract
INTRODUCTION Pulmonary rehabilitation (PR) following an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) reduces the risk of hospital admissions, and improves physical function and health-related quality of life. However, the safety and efficacy of in-hospital PR during the most acute phase of an AECOPD is not well established. This paper describes the protocol for a systematic review with meta-analysis to determine the safety and efficacy of inpatient acute care PR during the hospitalisation phase. METHODS AND ANALYSIS Medical literature databases and registries MEDLINE, EMBASE, Physiotherapy Evidence Database, Cumulative Index to Nursing and Allied Health Literature, Canadian Agency for Drugs and Technologies in Health, CENTRAL, Allied and Complementary Medicine Database, WHO trials portal and ClinicalTrials.gov will be searched for articles from inception to June 2021 using a prespecified search strategy. We will identify randomised controlled trials that have a comparison of in-hospital PR with usual care. PR programmes had to commence during the hospitalisation and include a minimum of two sessions. Title and abstract followed by full-text screening will be conducted independently by two reviewers. A meta-analysis will be performed if there is sufficient homogeneity across selected studies or groups of studies. The Population, Intervention, Comparator, Outcomes and Study characteristics framework will be used to standardise the data collection process. The quality of the cumulative evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluations framework. ETHICS AND DISSEMINATION AECOPD results in physical limitations which are amenable to PR. This review will assess the safety and efficacy of in-hospital PR for AECOPD. The results will be presented in a peer-reviewed publication and at research conferences. Ethical review is not required for this study.

Abstract
BACKGROUND The global rise of conflicts and catastrophes causes new challenges for western healthcare systems. There are obvious parallels between civilian disaster medicine and military combat care. The integration of disaster and deployment medicine into the medical curriculum thus seems necessary. OBJECTIVE What do medical students think about disaster and deployment medicine as part of the curriculum? Does participation in a voluntary disaster medicine course affect their view? MATERIAL AND METHODS While participating in an extracurricular lecture series on disaster and deployment medicine students (group 1) were asked about their personal views and prior experience in disaster medicine (20 questions). Students who did not attend the lecture (group 2) functioned as the control group. The statistical evaluation was performed descriptively and using Student's t test for independent subgroups. RESULTS The questionnaire was completed by 152 students (group 1: n = 78, group 2: n = 74). Only 10 students in group 1 and none in group 2 felt they had received an adequate amount of teaching in the field of disaster medicine. Medical students in both groups considered disaster medicine to be inadequately represented in the medical curriculum (group 1: 64% and group 2: 66%). Both groups were in favor of further expanding teaching in the field of disaster medicine (group 1: 72%, group 2: 54%, p = 0.001) and the development of e‑learning tools (group 1: 73%, group 2: 72%). DISCUSSION The medical students questioned considered disaster and deployment medicine to be an integral part of the curriculum. Despite some statistical differences between the two groups, the survey showed that medical students possess a great interest in disaster medicine. Both groups were in favor of further integrating e‑learning tools. A regular inclusion of disaster and deployment medicine into the spectrum of medical student teaching is warranted.

Abstract
Abstract
Background
Depression is one of the most common and serious diseases worldwide: According to WHO, more than 300 million people worldwide were affected by depression in 2015. In this group, the suicide rate is about 20 times higher than the population average. In Germany, around 10,000 people take their lives each year, many of them suffering from depression. The Institute for Quality and Efficiency in Health Care commissioned the Department of Health Care Management at the Berlin University of Technology to conduct a Health Technology Assessment on whether non-drug interventions influence coping with suicidal crises in unipolar depression.
Methods
A systematic search of primary studies and systematic reviews (e.g., in MEDLINE, PSYCINFO) was performed to assess the benefit of ambulatory crisis intervention programmes or psychosocial interventions compared to another non-drug treatment, drug treatment, inpatient treatment or no treatment/waiting list in adult suicidal patients with unipolar depression regarding patient-relevant outcomes (e.g., suicide attempts, suicidal ideation, depression).
Results
The search yielded a total of 4,159 hits. After two rounds of screening for relevance and removing duplicates, 4 studies remained for inclusion in the qualitative and quantitative analysis. The studies present RCTs assessing the effects of cognitive behavioural therapy (CBT) of the 2. and 3. wave - all short-term programmes focussing on suicidality. Results indicate a benefit of CBT compared to standard treatment, depending on the outcome, on the “wave” and on the time of follow up assessment.
Conclusions
There is some evidence on benefits of CBT for adult patients with suicidal crises in unipolar depression. However, the quality of the included RCTs is weak and evidence on benefits of other non-drug interventions in outpatient care is missing. Further research is needed to identify effective interventions, especially for the vulnerable weeks immediately after suicide attempt.
Key messages
Short term cognitive behavioural therapy with suicidal prevention elements may influence coping with suicidal crises in unipolar depression positively. Further research is needed to identify effective interventions for the vulnerable weeks immediately after suicide attempt.

Abstract
Abstract
Background
It is unknown whether renal pathology lesions in immunoglobulin A nephropathy (IgAN) correlate with renal outcomes over decades of follow-up.
Methods
In 1130 patients of the original Validation Study of the Oxford Classification for IgA Nephropathy (VALIGA) cohort, we studied the relationship between the MEST score (mesangial hypercellularity, M; endocapillary hypercellularity, E; segmental glomerulosclerosis, S; tubular atrophy/interstitial fibrosis, T), crescents (C) and other histological lesions with both a combined renal endpoint [50% estimated glomerular filtration rate (eGFR) loss or kidney failure] and the rate of eGFR decline over a follow-up period extending to 35 years [median 7 years (interquartile range 4.1–10.8)].
Results
In this extended analysis, M1, S1 and T1–T2 lesions as well as the whole MEST score were independently related with the combined endpoint (P < 0.01), and there was no effect modification by age for these associations, suggesting that they may be valid in children and in adults as well. Only T lesions were associated with the rate of eGFR loss in the whole cohort, whereas C showed this association only in patients not treated with immunosuppression. In separate prognostic analyses, the whole set of pathology lesions provided a gain in discrimination power over the clinical variables alone, which was similar at 5 years (+2.0%) and for the whole follow-up (+1.8%). A similar benefit was observed for risk reclassification analyses (+2.7% and +2.4%).
Conclusion
Long-term follow-up analyses of the VALIGA cohort showed that the independent relationship between kidney biopsy findings and the risk of progression towards kidney failure in IgAN remains unchanged across all age groups and decades after the renal biopsy.

Abstract
AIM To identify the genetic aetiology of a distinct leukoencephalopathy causing acute neurological regression in infancy with apparently complete clinical recovery. METHODS We performed trio whole genome sequencing (WGS) to determine the genetic basis of the disorder. Mitochondrial function analysis in cultured patient fibroblasts was undertaken to confirm the pathogenicity of candidate variants. RESULTS The patient presented at 18 months with acute hemiplegia and cognitive regression without obvious trigger. This was followed by clinical recovery over 4 years. MRI at disease onset revealed bilateral T2 hyperintensity involving the periventricular and deep white matter and MR spectroscopy of frontal white matter demonstrated a lactate doublet. Lactate levels and mitochondrial respiratory chain enzyme activity in muscle, liver and fibroblasts were normal. Plasma glycine was elevated. The MRI abnormalities improved. WGS identified compound heterozygous variants in BOLA3: one previously reported (c.136C>T, p.Arg46*) and one novel variant (c.176G>A, p.Cys59Tyr). Analysis of cultured patient fibroblasts demonstrated deficient pyruvate dehydrogenase (PDH) activity and reduced quantity of protein subunits of mitochondrial complexes I and II, consistent with BOLA3 dysfunction. Previously reported cases of multiple mitochondrial dysfunctions syndrome 2 (MMDS2) with hyperglycinaemia caused by BOLA3 mutations have leukodystrophy with severe, progressive neurological and multisystem disease. CONCLUSIONS We report a novel phenotype for MMDS2 associated with apparently complete clinical recovery and partial resolution of MRI abnormalities. We have identified a novel disease-causing variant in BOLA3 validated by functional cellular studies. Our patient's clinical course broadens the phenotypic spectrum of MMDS2 and highlights the potential for some genetic leukoencephalopathies to spontaneously improve.

Abstract
Objectives The aim of the study was to investigate circumstances surrounding perinatal transmissions of HIV (PHIVs) in the UK. Methods The National Study of HIV in Pregnancy and Childhood conducts comprehensive surveillance of all pregnancies in women diagnosed with HIV infection and their infants in the UK; reports of all HIV‐diagnosed children are also sought, regardless of country of birth. Children with PHIV born in 2006–2013 and reported by 2014 were included in an audit, with additional data collection via telephone interviews with clinicians involved in each case. Contributing factors for each transmission were identified, and cases described according to main likely contributing factor, by maternal diagnosis timing. Results A total of 108 PHIVs were identified. Of the 41 (38%) infants whose mothers were diagnosed before delivery, it is probable that most were infected in utero, around 20% intrapartum and 20% through breastfeeding. Timing of transmission was unknown for most children of undiagnosed mothers. For infants born to diagnosed women, the most common contributing factors for transmission were difficulties with engagement and/or antiretroviral therapy (ART) adherence in pregnancy (14 of 41) and late antenatal booking (nine of 41); for the 67 children with undiagnosed mothers, these were decline of HIV testing (28 of 67) and seroconversion (23 of 67). Adverse social circumstances around the time of pregnancy were reported for 53% of women, including uncertain immigration status, housing problems and intimate partner violence. Eight children died, all born to undiagnosed mothers. Conclusions Priority areas requiring improvement include reducing incident infections, improving ART adherence and facilitating better engagement in care, with attention to addressing the health inequalities and adverse social situations faced by these women.

Abstract
Background The Genius® dialysis system is increasingly used as an intermittent hemodialysis device in the setting of acute renal failure. Slow extended hemodialysis is preferred in the case of critical ill patients. In this study we established a safe and feasible citrate anticoagulation protocol for slow extended hemodialysis (SLED) with the Genius® system. Methods We compared six anticoagulation protocols using SLED in 34 critically ill patients with acute renal failure. One group (A) received only citrate anticoagulation. Four groups (B - D) were treated with citrate and different additional systemic anticoagulation. Patients in the last group (F) were anticoagulated with heparin and were free of citrate anticoagulation. The total number of treatments was 103. A 4% sodium citrate solution was infused into the arterial line of the dialysis device for citrate anticoagulation. The dialysis solution contained one mmol/L of calcium. No additional calcium supplementation was done. We monitored electrolyte, acid-base and cardiovascular status prospectively. Results Hemodialysis was well tolerated hemodynamically. Electrolytes remained stable throughout hemodialysis in all groups. The decrease in ionized and total calcium was within the expected, clinically acceptable range. Bicarbonate and pH levels increased during dialysis, especially if citrate was used. Conclusions Slow extended Genius® hemodialysis with citrate is well tolerated and offers a safe and effective alternative to systemic anticoagulation. (Int J Artif Organs 2008; 31: 43–8)

Abstract
AIM Cyclosporin A (CsA) causes renal toxicity. The underlying mechanisms are incompletely understood, but may involve renal hypoxia and hypoxia-inducible factors (Hifs). We sought for hypoxia and Hif in mouse kidneys with CsA-induced toxicity, assessed their time course, Hif-mediated responses and the impact of interventional Hif upregulation. METHODS Mice received CsA or its solvent cremophore for up to 6 weeks. Low salt diet (Na+ ↓) was given in combination with CsA to enhance toxicity. We assessed fine morphology, renal function, blood oxygen level-dependent magnetic resonance imaging under room air and following changes in breathing gas composition which correlate with vascular reactivity, pimonidazole adducts (which indicate O2 tensions below 10 mmHg), Hif-α proteins, as well as expression of Hif target genes. Stable Hif upregulation was achieved by inducible, Pax8-rtTA-based knockout of von Hippel-Lindau protein (Vhl-KO), which is crucial for Hif-α degradation. RESULTS Cyclosporin A transiently increased renal deoxyhaemoglobin (R2*). Augmented vascular reactivity was observed at 2 h, but decreased at 24 h after CsA treatment. Na+ ↓/CsA provoked chronic renal failure with tubular degeneration and interstitial fibrosis. Nephron segments at risk for injury accumulated pimonidazole adducts, as well as Hif-α proteins. Remarkably, Hif target gene expression remained unchanged, while factor-inhibiting Hif (Fih) was enhanced. Na+ ↓/CsA/Vhl-KO aggravated morpho-functional outcome of chronic renal CsA toxicity. CONCLUSIONS Cyclosporin A provokes episodic hypoxia in nephron segments most susceptible to chronic CsA toxicity. Fih is upregulated and likely blocks further Hif activity. Continuous tubular Hif upregulation via Vhl-KO worsens the outcome of chronic CsA-induced renal toxicity.

Abstract
Background The potential for HIV transmission between a pregnant woman and her unborn child was first recognized in 1982. Since then a complex package of measures to reduce risk has been developed. This project aims to review UK management of HIV in pregnancy as part of the British HIV Association (BHIVA) audit programme. Methods The National Study of HIV in Pregnancy and Childhood (NSHPC), a population-based surveillance study, provided data for pregnancies with an expected delivery date from 1/1/13 - 30/6/14. Services also completed a survey on local management policies. Data were audited against the 2012 BHIVA pregnancy guidelines. Results During the audit period 1483 pregnancies were reported and 112 services completed the survey. Use of dedicated multidisciplinary teams was reported by 99% although 26% included neither a specialist midwife nor nurse. 17% of services reported delays >1 week for HIV specialist review of women diagnosed antenatally. Problematic urgent HIV testing had been experienced by 9% of services although in a further 49% the need for urgent testing had not arisen. Delays of >2 h in obtaining urgent results were common. Antiretroviral therapy (ART) was started during pregnancy in 37% women with >94% regimens in accordance with guidelines. Late ART initiation was common, particularly in those with a low CD4 count or high viral load. Eleven percent of services reported local policy contrary to guidelines regarding delivery mode for women with a VL <50 copies/mL at ≥36 weeks. According to NSHPC reports 27% of women virologically eligible for vaginal delivery planned to deliver by CS. Conclusions Pregnant women in the UK are managed largely in accordance with BHIVA guidelines. Improvements are needed to ensure timely referral and ART initiation to ensure the best possible outcomes.

Abstract
OBJECTIVES The aim of the study was to compare maternal characteristics and pregnancy outcomes in women aged < 40 years and ≥ 40 years in a large unselected population of HIV-positive women delivering in the UK and Ireland between 2000 and 2014. METHODS Comprehensive population-based surveillance data on all HIV-positive pregnant women and their children seen for care in the UK and Ireland are collected through the National Study of HIV in Pregnancy and Childhood. All singleton and multiple pregnancies reported by the end of June 2015 resulting in live birth or stillbirth to women diagnosed with HIV infection before delivery and delivering in 2000-2014 were included. Logistic regression models were fitted in analyses examining the association between older maternal age and specific outcomes (preterm delivery and stillbirth). RESULTS Among 15 501 pregnancies in HIV-positive women, the proportion in older women (≥ 40 years) increased from 2.1% (73 of 3419) in 2000-2004 to 8.9% (510 of 5748) in 2010-2014 (P < 0.001). Compared with pregnancies in younger women, those in older women were more likely to result in multiple birth (3.0 vs. 1.9% in younger women; P = 0.03), stillbirth (adjusted odds ratio 2.39; P = 0.004) or an infant with a chromosomal abnormality (1.6 vs. 0.2%, respectively; P < 0.001). However, there was no increased risk of preterm delivery, low birth weight or mother-to-child HIV transmission among older mothers. CONCLUSIONS There has been a significant increase over time in the proportion of deliveries to women living with HIV aged ≥ 40 years, which has implications for pregnancy management, given their increased risk of multiple births, stillbirth and chromosomal anomalies, as also apparent in the general population.

Abstract
BACKGROUND Maternal smoking during pregnancy has been associated with increased risk of childhood overweight/obesity defined by body mass index (BMI). We examined its association with a range of adiposity measures and cardiovascular indicators in children aged 3-10 years. METHODS We used data from a cross-sectional study of schoolchildren across mainland Portuguese districts (2009-2010). We applied quantile regressions to examine maternal smoking associations with adiposity (n = 17 286), blood pressure (BP) and resting pulse rate (RPR) (n ≈ 2500) measures across the age range, adjusting for prenatal and early life factors. RESULTS Maternal smoking during pregnancy was associated with increases in offspring adiposity levels. The difference in median BMI between children of smokers and non-smokers was 0.39 kg m(-2) (95% confidence interval: 0.25, 0.53) in boys and 0.46 kg m(-2) (0.31, 0.62) in girls; 0.55 cm (0.24, 0.87) and 0.82 cm (0.45, 1.19), respectively, in median waist circumference; and 0.94 mm (0.49, 1.40) and 1.47 mm (0.87, 2.07) in median sum of (triceps, subscapular, suprailiac) skin-folds. The associations appeared to be stronger with increasing age. The differences in the 90th centile tended to be greater than those in median. There was no consistent association of maternal smoking with BP and RPR. CONCLUSIONS Children whose mother smoked during pregnancy had higher adiposity levels than children of non-smokers, across several measures, particularly among older children. Although there was no consistent association with cardiovascular indicators, maternal smoking association with childhood obesity may have implications for cardiovascular risk factors over the life course.

Abstract
This work proposes to examine the variability of the bone tissue healing process in the early period after the implantation surgery. The first part took into account the effect of variability of individual biochemical factors on the solid phase fraction, which is an indicator of the quality of the primary fixation and condition of its long-term behaviour. The next issue, addressed in this second part, is the effect of cumulative sources of uncertainties on the same problem of a canine implant. This paper is concerned with the ability to increase the number of random parameters to assess the coupled influence of those variabilities on the tissue healing. To avoid an excessive increase in the complexity of the numerical modelling and further, to maintain efficiency in computational cost, a collocation-based polynomial chaos expansion approach is implemented. A progressive set of simulations with an increasing number of sources of uncertainty is performed. This information is helpful for future implant design and decision process for the implantation surgical act.

Abstract
BACKGROUND The cobalamin E (cblE) (MTRR, methionine synthase reductase) and cobalamin G (cblG) (MTR, methionine synthase) defects are rare inborn errors of cobalamin metabolism leading to impairment of the remethylation of homocysteine to methionine. METHODS Information on clinical and laboratory data at initial full assessment and during the course of the disease, treatment, outcome and quality of life was obtained in a survey-based, retrospective study from physicians caring for patients with the CblE or CblG defect. In addition, data on enzyme studies in cultured skin fibroblasts and mutations in the MTRR and MTR gene were analysed. RESULTS In 11 cblE and 13 cblG patients, failure to thrive, feeding problems, delayed milestones, muscular hypotonia, cognitive impairment and macrocytic anaemia were the most frequent symptoms. Delay in diagnosis depended on age at first symptom and clinical pattern at presentation and correlated significantly with impaired communication abilities at follow-up. Eighteen/22 patients presented with brain atrophy or white matter disease. Biochemical response to treatment with variable combinations of betaine, cobalamin, folate was significant. The overall course was considered improving (n = 8) or stable (n = 15) in 96% of patients, however the average number of CNS symptoms per patient increased significantly over time and 16 of 23 patients were classified as developmentally delayed or severely handicapped. In vitro enzyme analysis data showed no correlation with outcome. Predominantly private mutations were detected and no genotype- phenotype correlations evident. CONCLUSIONS The majority of patients with the cblE and cblG defect show limited clinical response to treatment and have neurocognitive impairment.

Abstract
OBJECTIVE To investigate the association between duration of rupture of membranes (ROM) and mother-to-child HIV transmission (MTCT) rates in the era of combination antiretroviral therapy (cART). DESIGN The National Study of HIV in Pregnancy and Childhood (NSHPC) undertakes comprehensive population-based surveillance of HIV in pregnant women and children. SETTING UK and Ireland. POPULATION A cohort of 2398 singleton pregnancies delivered vaginally, or by emergency caesarean section, in women on cART in pregnancy during the period 2007-2012 with information on duration of ROM; HIV infection status was available for 1898 infants. METHODS Descriptive analysis of NSHPC data. MAIN OUTCOME MEASURES Rates of MTCT. RESULTS In 2116 pregnancies delivered at term, the median duration of ROM was 3 hours 30 minutes (interquartile range, IQR 1-8 hours). The overall MTCT rate for women delivering at term with duration of ROM ≥4 hours was 0.64% compared with 0.34% for ROM <4 hours, with no significant difference between the groups (OR 1.90, 95% CI 0.45-7.97). In women delivering at term with a viral load of <50 copies/ml, there was no evidence of a difference in MTCT rates with duration of ROM ≥4 hours, compared with <4 hours (0.14% for ≥4 hours versus 0.12% for <4 hour; OR 1.14, 95% CI 0.07-18.27). Among infants born preterm with infection status available, there were no transmissions in 163 deliveries where the maternal viral load was <50 copies/ml. CONCLUSIONS No association was found between duration of ROM and MTCT in women taking cART. TWEETABLE ABSTRACT Rupture of membranes of more than 4 hours is not associated with MTCT of HIV in women on effective ART delivering at term.

Abstract
Background: Somatic mutations affecting components of the Ras-MAPK pathway are a common feature of cancer, whereas germline Ras pathway mutations cause developmental disorders including Noonan, Costello, and cardio-facio-cutaneous syndromes. These ‘RASopathies' also represent cancer-prone syndromes, but the quantitative cancer risks remain unknown. Methods: We investigated the occurrence of childhood cancer including benign and malignant tumours of the central nervous system in a group of 735 individuals with germline mutations in Ras signalling pathway genes by matching their information with the German Childhood Cancer Registry. Results: We observed 12 cases of cancer in the entire RASopathy cohort vs 1.12 expected (based on German population-based incidence rates). This corresponds to a 10.5-fold increased risk of all childhood cancers combined (standardised incidence ratio (SIR)=10.5, 95% confidence interval=5.4–18.3). The specific cancers included juvenile myelomonocytic leukaemia=4; brain tumour=3; acute lymphoblastic leukaemia=2; rhabdomyosarcoma=2; and neuroblastoma=1. The childhood cancer SIR in Noonan syndrome patients was 8.1, whereas that for Costello syndrome patients was 42.4. Conclusions: These data comprise the first quantitative evidence documenting that the germline mutations in Ras signalling pathway genes are associated with increased risks of both childhood leukaemia and solid tumours.

Abstract
Sotos syndrome is a well-known overgrowth syndrome characterized by excessive growth during childhood, macrocephaly, distinctive facial appearance and learning disability. This disorder is caused by mutations or deletions in NSD1 gene. The aim of this study is to examine the relationship between the neuroimaging and clinical features of children with Sotos syndrome. Six Turkish children with Sotos syndrome were followed up about 3-7 years. The diagnosis was confirmed with molecular genetic analysis. We identified the pathogenic NSD1 mutation including three novel in all patients. All the patients had a characteristic facial gestalt of Sotos syndrome consisting of triangular face with prominent forehead, frontoparietal sparseness of hair and small nose. However, the degree of psychomotor and intellectual development was variable. Severe learning defect and speech delay were remarkable in two patients. The neuroimaging analysis showed abnormalities in four of six patients including bilateral large ventricles, thinning of the corpus callosum and persistent cavum septum pellucidum et vergae. Typical craniofacial appearance is the primary finding for the diagnosis of the disease even in the infantile period. However, the degree of psychomotor and intellectual development is very variable and does not correlate with the neuroimaging findings.

Abstract
Medical intervention for lysosomal storage disorders becomes part of life, shaping the reality of the condition for affected individuals and families. Enzyme replacement therapy (ERT) is available to treat some lysosomal storage disorders. ERT is costly and time consuming, requiring frequent hospital visits to receive intravenous infusions. This qualitative study sought to explore the impact of receiving ERT for a lysosomal storage disorder on the health related quality of life (HRQoL) of young patients and their families. Fifteen semi-structured interviews were conducted with young people and parents and siblings of young people accessing ERT for Pompe disease, Gaucher disease or mucopolysaccharidosis types I or II living in Victoria, Australia. Interviews were transcribed then analyzed thematically. The biopsychosocial model assisted in interpreting themes. Findings revealed positive attitudes towards ERT, with noticed improvements in physical and psychosocial well-being. Participants prioritised intervention over other activities and provided suggestions for improving current service delivery. Communication with family members and professionals was deemed important, especially in respect to information provision. Participants described challenges associated with living with a lysosomal storage disorder and receiving ERT and coping strategies, such as positive thinking and ways to manage uncertainty. These findings provide valuable insights into the impact of living with a chronic genetic condition and receiving intensive treatment on HRQoL.

Abstract
AIM Von Hippel-Lindau protein (VHL) provides the degradation of hypoxia-inducible factor (HIF). Tetracycline-induced, Pax8-rtTA-based knockout of VHL (VHL-KO) affects all renal tubules and periportal hepatocytes and leads to sustained upregulation of HIF. Here, we study the phenotype of VHL-KO in both organs, the time course of changes, and long-term morpho-functional outcome. METHODS Mice with doxycycline-induced VHL-KO and controls (CON) were followed for up to 9 months. Systemic and tissue parameters were evaluated using clinical chemistry, histology, immunohistochemistry, RT-PCR and in situ hybridisation. RESULTS At day 3 following VHL-KO, substantial abundance of HIF-1α and -2α was detected in the nuclei of hepatocytes and renal tubular epithelia. Hypoxia, induced by bleeding anaemia, did not further augment HIF signal. Erythropoietin mRNA was detectable in hepatocytes but not in the kidney. Vascular endothelial growth factor mRNA was upregulated in kidney but not in liver. At day 7 following VHL-KO, the renal capillary density was enhanced, reaching its maximum at day 14. Blood haemoglobin increased constantly up to day 28 (23.3 vs. 15.8 g dL(-1) , VHL-KO vs. CON). Thereafter, it was kept within the normal range by weekly blood collections. Pathological changes were absent from kidney and liver 9 months after VHL-KO. CONCLUSIONS Inducible, Pax8-rtTA-based deletion of VHL leads to organ-specific expression of epithelial HIF and erythropoietin in liver and kidney without causing pathological changes. Uniform, maximal and sustained HIF activation along the renal tubule may serve to study the potential benefits of hypoxia adaptation in experimental renal injury.

Abstract
Tooth morphogenesis involves patterning through the activity of epithelial signaling centers that, among other molecules, secrete Sonic hedgehog (Shh). While it is known that Shh responding cells need intact primary cilia for signal transduction, the roles of individual cilia components for tooth morphogenesis are poorly understood. The clinical features of individuals with Ellis-van Creveld syndrome include various dental anomalies, and we show here that absence of the cilial protein Evc in mice causes various hypo- and hyperplasia defects during molar development. During first molar development, the response to Shh signaling is progressively lost in Evc-deficient embryos and, unexpectedly, the response consistently disappears in a buccal to lingual direction. The important role of Evc for establishing the buccal-lingual axis of the developing first molar is also supported by a displaced activity of the Wnt pathway in Evc mutants. The observed growth abnormalities eventually manifest in first molar microdontia, disruption of molar segmentation and symmetry, root fusions, and delayed differentiation. Analysis of our data indicates that both spatially and temporally disrupted activities of the Shh pathway are the primary cause for the variable dental anomalies seen in patients with Ellis-van Creveld syndrome or Weyers acrodental dysostosis.

Abstract
Multiple myeloma (MM) is a malignancy with excessive production of monoclonal proteins. At disease presentation 30% of MM patients have significant renal impairment which may progress to renal failure requiring dialysis. Besides chemotherapy extracorporeal elimination procedures such as plasma exchange have been applied as adjuvant strategies to eliminate free light chains from circulating blood, however the efficacy was poor with older techniques. We report about a highly efficient method to eliminate serum free light chain (sFLC) using a newly designed protein leaking membrane in patients suffering from sFLC induced acute renal failure. The protein leaking membrane (HCO 1100) is characterized by increased pore size facilitating elimination of middle molecules such as sFLC kappa (22.5 kD). The HCO 1100 membrane was applied in a hemodialysis and hemodiafiltration mode and compared to standard procedures (high flux hemodialysis, hemodiafiltration and plasma exchange). Hemodiafiltration with the protein leaking membrane HCO 1100 was superior to all other extracorporeal replacement strategies in eliminating sFLC-kappa from circulating blood. A median blood reduction rate of 40.8% (range 13.9% - 66.4%) was achieved during hemodiafiltration. The corresponding peak clearance rate was 25 ml/min. Importantly, the poorest elimination rate was achieved by plasma exchange followed by standard high flux hemodialysis. Extracorporeal elimination strategies with the protein leaking membrane HCO 1100 may be a promising adjuvant treatment strategy for patients with sFLC nephropathy requiring dialysis. Hemodiafiltration and to lesser extend also hemodialysis with the HCO 1100 hemofilter are able to eliminate substantial amounts of sFLC kappa in MM patients.

Abstract
BACKGROUND Ten years ago, avoidance measures such as the performance of latex-free operations were implemented in children with spina bifida. Since then, latex sensitization and latex allergy have decreased in this high-risk group. OBJECTIVE To study the effect of primary latex-free prophylaxis on the prevalence of allergic diseases and atopy as a marker for sensitization spreading in children with spina bifida. METHODS One hundred and twenty children with spina bifida born after the introduction of latex-free prophylaxis and operated on under latex-free conditions ('current group') were examined for latex sensitization, latex allergy, sensitization to aero- and food allergens and allergic diseases. Results were compared to a 'historic' (not latex-free operated) group of children with spina bifida and comparable age (n = 87) and to a recent sample of children from the general population (n = 12,403). RESULTS In comparison with the 'historic group', latex sensitization (55% vs 5%, P < 0.001) and latex allergy (37% vs 0.8%, P < 0.001) were significantly reduced in the 'current group'. Furthermore, a significant reduction could be demonstrated for sensitization to aeroallergens (41.4% vs 20.8%, P = 0.001) and for allergic diseases (35% vs 15%, P = 0.001). The prevalence for atopy, sensitization to aero-/foodallergens and for allergic diseases in children of the 'current group' was similar to those in children of the weighted population sample. CONCLUSIONS Latex avoidance in children with spina bifida prevents latex sensitization and latex allergy. Additionally, it also seems to prevent sensitization to other allergens and allergic diseases which might be explained by the prevention of sensitization spreading.
