Electronic institutional review board systems (eIRBs) have become an integral component in ensuring compliance with Human Research Protection Program (HRPP) and IRB requirements. Despite this, few of these systems are configured to administer the single IRB (sIRB) process mandated by the National Institutes of Health (NIH) for multisite research. We interviewed 103 sIRB administrators, chairs, members, and staff members about their experiences with sIRB multisite research review. We observed three main obstacles to adapting existing eIRB systems to accommodate the sIRB process: (1) Existing systems are not designed for sIRBs and are not configured to administer sIRB responsibilities, (2) they are not interoperable, and (3) resources to improve existing systems are lacking. Our findings suggest that IRBs that act as an sIRB will need major changes to their electronic systems in order to accommodate sIRB processes. These difficulties threaten both the ability of IRBs to focus on ethical rather than bureaucratic problems and the efficiency of multisite trials.

School closures were one of the earlier actions taken as the world tried to contain the COVID-19 outbreak, a decision impacting nearly three-fourths of the learners worldwide. One year into the pandemic, over 200 million students still faced disruptions to their education. Nearing the end of another academic year that has occurred entirely during the pandemic, many schools remained fully or partially closed for in-person education, altering routines and representing potential hardships to the next generation and their families. This article will explore the potential impacts of school closures on children and adolescents related to increased screen time, irregular sleep patterns, less balanced diets, learning difficulties, and changes in social interaction. In addition, we note broader familial difficulties likely accompanying the loss of the mitigating effects of schools and their associated support systems, such as parental stress and work responsibilities, loss of employment, intimate partner violence, child abuse and neglect, and parental substance abuse, which appear to have increased during the pandemic. Considering what is known about the impact from previous natural catastrophes, the populations at risk, and the early but not yet definitive data from the current pandemic, we stress the urgent need for robust data as we prepare for a new academic year in the Northern Hemisphere. Although we currently lack consistent and complete data, signs for concern include a rise in pediatric emergency room visits for mental health and substance use issues in many parts of the world. This paper aims to stimulate a discussion about the potential mental health effects of school closures for children and adolescents in the context of a pandemic.

Sotos syndrome is an overgrowth-intellectual disability (OGID) syndrome caused by NSD1 pathogenic variants and characterized by a distinctive facial appearance, an intellectual disability, tall stature and/or macrocephaly. Other associated clinical features include scoliosis, seizures, renal anomalies, and cardiac anomalies. However, many of the published Sotos syndrome clinical descriptions are based on studies of children; the phenotype in adults with Sotos syndrome is not yet well described. Given that it is now 17 years since disruption of NSD1 was shown to cause Sotos syndrome, many of the children first reported are now adults. It is therefore timely to investigate the phenotype of 44 adults with Sotos syndrome and NSD1 pathogenic variants. We have shown that adults with Sotos syndrome display a wide spectrum of intellectual ability with functioning ranging from fully independent to fully dependent. Reproductive rates are low. In our cohort, median height in adult women is +1.9 SD and men +0.5 SD. There is a distinctive facial appearance in adults with a tall, square, prominent chin. Reassuringly, adults with Sotos syndrome are generally healthy with few new medical issues; however, lymphedema, poor dentition, hearing loss, contractures and tremor have developed in a small number of individuals.

Accessibility refers to whether a product or service is usable by all regardless of disability status. Principles of accessibility are not limited to physical spaces (such as stairs or curbs) – the same principles apply to websites and public facing documents. There are guidelines to follow to make documents, web pages, presentations, products, and research findings more accessible to people with disabilities. This tip sheet offers an introduction to accessibility and will be followed by tip sheets that focus on specifics.

Purpose The LZTR1 gene has been associated with schwannomatosis tumor predisposition and is located in a region that is deleted in the great majority (89%) of patients with 22q11.2 deletion syndrome (22q11.2DS). Since it is known that approximately 1 in 500 people in the general population will develop a sporadic schwannoma and there are no reports of the occurrence of schwannoma in 22q11.2DS, we investigated whether whole-gene deletion of LZTR1 occurs in schwannomatosis and assessed the risk of schwannoma in 22q11.2DS. Methods We assessed the genetic testing results for LZTR1-associated schwannomatosis and the clinical phenotypes of patients with 22q11.2DS. Results There were no reports of schwannoma in over 1,500 patients with 22q11.2DS. In addition, no patients meeting clinical diagnostic criteria for schwannomatosis had a whole-gene deletion in LZTR1. Only 1 patient in 110 with an apparently sporadic vestibular schwannoma had a constitutional whole-gene deletion of LZTR1. Conclusion People with a large 22q11.2 deletion may have a reduced risk of developing a schwannoma compared to the general population.

Introduction Vascularised composite allotransplantation (VCA) permits like-for-like reconstruction following extensive soft tissue injuries. The initial management of extensive soft tissue injury can lead to the development of anti-HLA antibodies through injury, transfusion and cadaveric grafting. The role of antibody-mediated rejection, donor-specific antibodies and graft rejection in the context of VCA remains unclear. This systematic review aimed to determine whether pre-operative management strategies influence immunological outcome following VCA. Method A systematic review of MEDLINE, EMBASE and CINAHL using a PRISMA-compliant methodology up to February 2019 was conducted. Pre-operative, procedural and long-term outcome data were collected and recorded for all VCA recipients on an individual patient basis. Result The search revealed 3,847 records of which 114 met inclusion criteria and reported clinical data related to 100 patients who underwent 129 VCA transplants. Trauma (50%) and burns (15%) were the most frequent indications for VCA. Of all 114 studies, only one reported acute resuscitative management. Fifteen patients (14.7%) were sensitized prior to reconstructive transplantation with an 80% incidence of acute rejection in the first post-operative year. Seven patients demonstrated graft vasculopathy, only one of whom had demonstrated panel reactive antibodies. Conclusion Currently employed acute management strategies predispose to the development of anti-HLA antibodies, adding to the already complex immunological challenge of VCA. Early appropriate care is warranted in patients with extensive soft tissue loss where the resuscitative needs should be balanced against strategies to mitigate the immunological burden, particularly as reconstructive transplantation becomes a feasible option for future soft tissue coverage. Take-home message Acute resuscitative management may sensitise potential transplant recipients following major soft tissue injury. Early appropriate care is warranted.

Background Clinical genetics is a small specialty with around 70 trainees nationally. New trainees traditionally have a period of observing clinics led by consultants and experienced genetic counsellors before leading their own clinic. This is an important time in which they learn practical and communication skills with respect to approaching a consultation, however, the experience can be variable dependent on the centre. In light of the coronavirus pandemic, knowing that many new trainees would not be able to access this vital induction period, we devised a virtual induction programme. Methods A group of clinical geneticists from three UK centres, including GOSH, worked in collaboration with the GOSH Clinical Simulation Team to devise and deliver a programme that would be accessible to all new trainees. Important topics for discussion were agreed; example consultations were filmed, with the help of actors; and trainee simulations were planned. Results The virtual induction runs live over two days, with homework, in the form of the filmed consultations that can be accessed at any time. The first day has been completed, delivering training to around 20 new trainees. The feedback we have received from both trainees and training programme directors has been overwhelmingly positive. Discussion Given the ongoing impact of the coronavirus pandemic, creative ways of delivering training are flourishing. We have created a bank of videos and presentations, as well as a template for future induction sessions, ensuring a basic level of equity between trainees at different genetics centres. Conclusion Virtual induction tools are a valuable and vital addition to new trainee induction to ensure equity of training, both during the current pandemic and beyond. This approach would work very well on a national level for other small specialties; or on a regional or local level for larger specialties.

Introduction Vascularised composite allotransplantation (VCA) permits like-for-like reconstruction following extensive soft tissue injuries. The initial management of extensive soft tissue injury can lead to the development of anti-HLA antibodies through injury-related factors, transfusion and cadaveric grafting. The role of antibody-mediated rejection, donor-specific antibody formation and graft rejection in the context of VCA remains unclear. This systematic review aimed to determine whether pre-transplant management strategies influence immunological outcome following VCA. Methods A systematic review of MEDLINE, EMBASE and CINAHL using a PRISMA-compliant methodology up to February 2019 was conducted.

Fifteen patients were sensitised prior to reconstructive transplantation with an 80%%incidence of acute rejection in the first post-operative year. Seven patients demonstrated graft vasculopathy, only one of whom had demonstrated panel reactive antibodies. Conclusions Currently employed acute management strategies may predispose to the development of anti-HLA antibodies, adding to the already complex immunological challenge of VCA. To determine whether association between pre-transplant management and outcomes exists, further refinement of international registries is required.

Women who inherit a mutated copy of the BRCA gene have a higher lifetime risk of developing breast cancer. No large epidemiological studies exist looking at BRCA mutation carriers in UK populations. All patients with BRCA1/BRCA2 mutation identified between 1995 and 2015 were included. Individuals were identified from a prospectively gathered data base. Genetics case-notes were obtained and retrospective analysis performed. 581 female BRCA mutation carriers were identified with a median age of 34 (18-81) at the time of testing. Of the 301 women who underwent diagnostic testing (symptomatic) 246 had been diagnosed with breast cancer, 89 with ovarian cancer and 37 had both at time of testing. Median age at diagnostic test was 51 (25-81). 33% of women underwent risk-reducing mastectomies (RRM); median age at surgery 45. This compares with 37% of women in this diagnostic group who underwent Risk-reducing bilateral salpingo-oopherectomies (RRBSO) at a median age of 46. Two hundred and eighty women underwent predictive testing (family history, asymptomatic), median age 36 (18-81). 34% of women in this predictive group underwent RRM, median age 37. There was a 29% uptake of RRBSO (median age 44 years). Fifteen women (5%) developed breast cancer after being tested; none of these had undergone RRS. This unique study of all BRCA mutation carriers in Wales shows considerable variation in uptake of RRS. The decision to undergo RRS is complex and involves a number of factors, including a woman's age and life stage. As BRCA testing becomes more frequent and more gene mutation carriers are identified there will be significant implications for service allocation, screening demands, and provision of risk-reducing surgery for this high-risk patient group.

Background Colorectal cancer (CRC) is the most common cancer affecting both men and women. Survivors of CRC often experience various physical and psychological effects arising from CRC and its treatment. These effects may last for many years and adversely affect QoL, and they may not be adequately addressed by standard specialist-based follow-up. Optimal management of these effects should harness the expertise of both primary care and specialist care. Shared models of care (involving both the patient’s primary care physician [PCP] and specialist) have the potential to better support survivors and enhance health system efficiency. Methods/design SCORE (Shared care of Colorectal cancer survivors) is a multisite randomised controlled trial designed to optimise and operationalise a shared care model for survivors of CRC, to evaluate the acceptability of the intervention and study processes, and to collect preliminary data regarding the effects of shared care compared with usual care on a range of patient-reported outcomes. The primary outcome is QoL measured using the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire. Secondary outcomes are satisfaction with care, unmet needs, continuity of care and health resource use. The shared care model involves replacement of two routine specialist follow-up visits with PCP visits, as well as the provision of a tailored survivorship care plan and a survivorship booklet and DVD for CRC survivors. All consenting patients will be randomised 1:1 to either shared care or usual care and will complete questionnaires at three time points over a 12-month period (baseline and at 6 and 12 months). Health care resource use data will also be collected and used to evaluate costs. Discussion The evaluation and implementation of models of care that are responsive to the holistic needs of cancer survivors while reducing the burden on acute care settings is an international priority. Shared care between specialists and PCPs has the potential to enhance patient care and outcomes for CRC survivors while offering improvements in health care resource efficiency. If the findings of the present study show that the shared care intervention is acceptable and feasible for CRC survivors, the intervention may be readily expanded to other groups of cancer survivors.

Purpose Conflicts of interest (COIs) are important ethical concerns because they may affect scientific decision making, research integrity, and the safety and fairness of studies. No research to date has examined COIs of single institutional review boards (sIRBs), which are now mandated by the National Institutes of Health, and will be by the revised Common Rule in 2020, for all multisite research. This study investigated how different types of sIRBs manage their own COIs by documenting existing processes for and comparing commercial, government, and academic sIRBs. Method One hundred three personnel from 20 commercial, government, or academic sIRBs participated in semistructured interviews about their processes for and experiences with managing COIs when conducting multisite research review. Results Variability in COI management policies exist across types of sIRBs. Commercial sIRBs were aware of their own COIs given their for-profit model, and managed them by using firewalls, relying on external reviewers, and turning down potential clients. Government sIRBs described unique COIs stemming from the same agency funding the sIRB and the research being reviewed. They addressed these by discussing concerns about COIs, using firewalls, relying on nonaffiliated reviewers, and having broad COI policies. In contrast to commercial and government sIRBs, academic sIRBs did not report any specific policies to manage their COIs, which are similar to those of local IRBs. Conclusions As sIRBs become increasingly common, researchers will need to weigh the different COIs inherent to each type of sIRB. Additionally, academic sIRBs may consider implementing specific policies for managing their COIs.

We demonstrate the use of the near-infrared attenuation coefficient, measured using optical coherence tomography (OCT), in longitudinal assessment of hypertrophic burn scars undergoing fractional laser treatment. The measurement method incorporates blood vessel detection by speckle decorrelation and masking, and a robust regression estimator to produce 2D en face parametric images of the attenuation coefficient of the dermis. Through reliable co-location of the field of view across pre- and post-treatment imaging sessions, the study was able to quantify changes in the attenuation coefficient of the dermis over a period of ~20 weeks in seven patients. Minimal variation was observed in the mean attenuation coefficient of normal skin and control (untreated) mature scars, as expected. However, a significant decrease (13 ± 5%, mean ± standard deviation) was observed in the treated mature scars, resulting in a greater distinction from normal skin in response to localized damage from the laser treatment. By contrast, we observed an increase in the mean attenuation coefficient of treated (31 ± 27%) and control (27 ± 20%) immature scars, with numerical values incrementally approaching normal skin as the healing progressed. This pilot study supports conducting a more extensive investigation of OCT attenuation imaging for quantitative longitudinal monitoring of scars. (Figure presented.)

Clinical Genetics services provide a diagnostic, counselling and genetic testing service for children and adults affected by, or at risk of, a genetic condition, most of which are rare, and/or genetically heterogeneous. Appropriate triage of referrals is crucial to ensure that the most urgent referrals are seen as quickly as possible, without negatively impacting the waiting times of less urgent cases. We aimed to examine triage practice in six Clinical Genetic centres across the United Kingdom and Ireland. Thirteen simulated referrals were drafted based on common referrals to Clinical Genetics. Copies of each referral were forwarded to each centre, where 10 nominated clinicians were asked to triage each referral. Triaged referrals were returned to the coordinating author for analysis. An electronic questionnaire was contemporaneously completed by clinical leads in each unit to gather local demographic details and local operating procedures relevant to triage. Widespread inconsistencies were noted both within and between units, with respect to the acceptance of referrals to the services, prioritisation and designated clinic type. Referral rates, staffing levels and waiting lists varied widely between units. Inconsistencies observed between units are likely influenced by a number of factors, including staffing levels, referral rates and average family size. Inconsistency within units likely reflects the complex nature of many Clinical Genetic referrals, and triage guidelines should help improve decision-making in this setting.

New federal policies require single IRB review for multisite studies, but many questions remain about how these IRBs will use local knowledge. The findings from our study, the first to examine how single IRBs perceive needs for local knowledge, reveal several challenges. Study respondents identified four potentially relevant types of local knowledge: about culture and linguistics, about geography and socioeconomics, about the researchers, and about the institutions. Such knowledge can potentially be obtained through local sites, but single IRBs may be unaware of potentially relevant local information, and lack of informal relationships may impede single IRBs’ reviews and interactions with researchers. While a recent, commonly used, standardized single‐IRB form asks three basic questions about local information, our findings suggest potential needs for additional information and, thus, have important implications for practice, policy, and research.

The new National Institutes of Health (NIH) Policy on the Use of a Single Institutional Review Board (sIRB) for Multi-Site Research was adopted primarily to simplify and speed the review of complex multisite clinical trials. However, speeding review requires overcoming a number of obstacles. Perhaps the most substantial obstacle is the time and effort needed to develop reliance agreements among the participating sites. We conducted 102 semistructured interviews with sIRB personnel, including directors, chairs, reviewers, and staff, from 20 IRBs that acted as sIRBs for multisite research, including 6 commercial/independent sIRBs, and 10 university-based academic and 4 federal sIRBs. Almost without exception, the interviewees agreed that reliance agreements were complex, difficult to develop, and time-consuming. A major problem for relying sites was that different agreements specified different responsibilities for the relying sites. Attitudes differed about whether these problems will be resolved as IRB staff and managers become more experienced with sIRBs. However it is clear that the process of developing reliance agreements must be simplified. Federal assistance in standardizing at least some sections of reliance agreements might reduce the difficulties involved.

This study presents the first in vivo longitudinal assessment of scar vasculature in ablative fractional laser treatment using optical coherence tomography (OCT). A method based on OCT speckle decorrelation was developed to visualize and quantify the scar vasculature over the treatment period. Through reliable co-location of the imaging field of view across multiple imaging sessions, and compensation for motion artifact, the study was able to track the same scar tissue over a period of several months, and quantify changes in the vasculature area density. The results show incidences of occlusion of individual vessels 3 days after the first treatment. The subsequent responses ˜20 weeks after the initial treatment show differences between immature and mature scars. Image analysis showed a distinct decrease (25 ± 13%, mean ± standard deviation) and increase (19 ± 5%) of vasculature area density for the immature and mature scars, respectively. This study establishes the feasibility of OCT imaging for quantitative longitudinal monitoring of vasculature in scar treatment. En face optical coherence tomography vasculature images pre-treatment (top) and ˜20 weeks after the first laser treatment (bottom) of a mature burn scar. Arrows mark the same vessel pattern.

Background\ud Many patients who require an interpreter have difficulty remembering information from their medical consultations. Memory aids such as consultation audio-recordings may be of benefit to these patients. However, there is no established means of measuring patients’ memory of medical information.\ud \ud Objectives\ud This study aimed to develop a method for eliciting and coding recall of medical information in non-English-speaking patients.\ud \ud Design\ud This method, called Patient-Interpreter-Clinician coding (PICcode), was developed in the context of a phase II trial conducted in two outpatient oncology clinics in Melbourne, Australia, and was refined iteratively through consultation with an expert panel and piloting. Between-coder differences in early versions of the coding system were resolved through discussion and consensus resulting in refinements to PICcode.\ud \ud Results\ud The final version of PICcode involved transcribing, translating and coding of audio-recorded consultations and semi-structured interviews (SSI). The SSIs were designed to elicit patients’ free-recall of medical information. Every unit of medical information in the consultation was identified and categorized in a coding tree. SSIs were coded to identify the extent to which information was recalled from the consultation.\ud \ud Discussion\ud The iterative changes involved in developing PICcode assisted in clarifying precise details of the process and produced a widely applicable coding system. PICcode is the most comprehensively described method of determining the amount of information that patients who use an interpreter recall from their medical consultations. PICcode can be adapted for English-speaking patients and other healthcare populations.

Decisions about the appropriate use of animals in research are largely made by Institutional Animal Care and Use Committees (IACUCs). Several commentators claim that scientists exert excessive influence on IACUC decisions. We studied 87 protocol reviews from 10 IACUCs to assess whether any group of participants appeared to dominate the protocol discussions. Audio recordings of the meetings were coded to capture the topics of the discussions. We found that animal research scientists made the largest total number of topic mentions while community members made the fewest. On a per person basis, chairpersons and attending veterinarians made the most mentions. Scientists presented the largest number of protocols, and the subsequent discussions tended to contain the same topics mentioned in the presentations. The large number of protocols presented by scientists and their total number of comments made during protocol discussions suggest that scientists may significantly influence IACUC decision making.

L'autrice risponde per sommi capi alle critiche dei diversi commentatori, individuando i tre punti centrali che, a suo parere, sono complessivamente emersi: l'importanza del contesto, lo sviluppo del soggetto e le implicazioni cliniche del mio modello terapeutico. Dopo avere riconosciuto la fondatezza delle critiche e valorizzato gli argomenti dei colleghi, ribadisce le proprie posizioni e resta ferma in esse. La risposta piů articolata si rivolge all'obiezione di Roggero che riguardava la nascita del soggetto come espressione di autodeterminazione non mutuata dall'esterno. Harrison sostiene che tale autodeterminazione av-viene nel momento il cui il paziente va oltre il rapporto con l'analista e cambia qualcosa nel proprio rapporto con il proprio contesto d'origine inteso nel senso piů ampio.

Women who inherit a mutated copy of the BRCA-1 or BRCA-2 genes have a higher lifetime risk of developing breast cancer. There have been no large epidemiological studies looking at BRCA-positive patients in the UK.

Background With burn injuries involving a large total body surface area (TBSA), the body can enter a state of breakdown, resulting in a condition similar to that seen with severe lack of proper nutrition. In addition, destruction of the effective skin barrier leads to loss of normal body temperature regulation and increased risk of infection and fluid loss. Nutritional support is common in the management of severe burn injury, and the approach of altering immune system activity with specific nutrients is termed immunonutrition. Three potential targets have been identified for immunonutrition: mucosal barrier function, cellular defence and local or systemic inflammation. The nutrients most often used for immunonutrition are glutamine, arginine, branched-chain amino acids (BCAAs), omega-3 (n-3) fatty acids and nucleotides. Objectives To assess the effects of a diet with added immunonutrients (glutamine, arginine, BCAAs, n-3 fatty acids (fish oil), combined immunonutrients or precursors to known immunonutrients) versus an isonitrogenous diet (a diet wherein the overall protein content is held constant, but individual constituents may be changed) on clinical outcomes in patients with severe burn injury. Search methods The search was run on 12 August 2012. We searched the Cochrane Injuries Group's Specialised Register, The Cochrane Library, MEDLINE (OvidSP), Embase (OvidSP), ISI WOS SCI-EXPANDED & CPCI-S and four other databases. We handsearched relevant journals and conference proceedings, screened reference lists and contacted pharmaceutical companies. We updated this search in October 2014, but the results of this updated search have not yet been incorporated. Selection criteria Randomised controlled trials comparing the addition of immunonutrients to a standard nutritional regimen versus an isonitrogenated diet or another immunonutrient agent. Data collection and analysis Two review authors were responsible for handsearching, reviewing electronic search results and identifying potentially eligible studies. Three review authors retrieved and reviewed independently full reports of these studies for inclusion. They resolved differences by discussion. Two review authors independently extracted and entered data from the included studies. A third review author checked these data. Two review authors independently assessed the risk of bias of each included study and resolved disagreements through discussion or consultation with the third and fourth review authors. Outcome measures of interest were mortality, hospital length of stay, rate of burn wound infection and rate of non-wound infection (bacteraemia, pneumonia and urinary tract infection). Main results We identified 16 trials involving 678 people that met the inclusion criteria. A total of 16 trials contributed data to the analysis. Of note, most studies failed to report on randomisation methods and intention-to-treat principles; therefore study results should be interpreted with caution. Glutamine was the most common immunonutrient and was given in seven of the 16 included studies. Use of glutamine compared with an isonitrogenous control led to a reduction in length of hospital stay (mean stay -5.65 days, 95% confidence interval (CI) -8.09 to -3.22) and reduced mortality (pooled risk ratio (RR) 0.25, 95% CI 0.08 to 0.78). However, because of the small sample size, it is likely that these results reflect a false-positive effect. No study findings suggest that glutamine has an effect on burn wound infection or on non-wound infection. All other agents investigated showed no evidence of an effect on mortality, length of stay or burn wound infection or non-wound infection rates. Authors' conclusions Although we found evidence of an effect of glutamine on mortality reduction, this finding should be taken with care. The number of study participants analysed in this systematic review was not sufficient to permit conclusions that recommend or refute the use of glutamine. Glutamine may be effective in reducing mortality, but larger studies are needed to determine the overall effects of glutamine and other immunonutrition agents.

A 54 year old man presented with numerous cutaneous schwannomas, cranial nerve lesions, and spinal cord lesions, but no evidence of vestibular nerve involvement. There was no family history of neurocutaneous lesions. To help discriminate between the various possible diagnoses in this patient, molecular analysis of two cutaneous schwannomas was undertaken. An identical point mutation in the NF2 gene in the two anatomically distinct tumours was found, confirming this as a case of NF2 mosaicism.

We present an automated, label-free method for lymphangiography of cutaneous lymphatic vessels in humans in vivo using optical coherence tomography (OCT). This method corrects for the variation in OCT signal due to the confocal function and sensitivity fall-off of a spectral-domain OCT system and utilizes a single-scattering model to compensate for A-scan signal attenuation to enable reliable thresholding of lymphatic vessels. A segment-joining algorithm is then incorporated into the method to mitigate partial-volume effects with small vessels. The lymphatic vessel images are augmented with images of the blood vessel network, acquired from the speckle decorrelation with additional weighting to differentiate blood vessels from the observed high decorrelation in lymphatic vessels. We demonstrate the method with longitudinal scans of human burn scar patients undergoing ablative fractional laser treatment, showing the visualization of the cutaneous lymphatic and blood vessel networks.

Quest'articolo rappresenta un tentativo di integrare l'attuale teoria dello sviluppo e la teoria psicoanalitica, nello studio dell'azione terapeutica. Io spiego l'azione terapeutica come qualcosa che si svolge simultaneamente in domini multipli. Perciň, il "modello a sandwich" aggiunge due domini a quello di cui si occupa la teoria psicoanalitica. Questi domini aggiunti non descrivono il cambiamento in termini lineari, perché ubbidiscono ai principi generali dei sistemi non lineari. Essi tematizzano differenti livelli temporali. Invece di spiegare i cambiamenti che avvengono nel corso di minuti, ore e anni, descrivono quelli che avvengono in tempi molto lunghi e molto brevi: secoli, secondi e frazioni di secondo. I tempi molto lunghi descrivono, per esempio, la formazione dei fiumi. Quelli molto brevi, invece, descrivono i micro-processi di interazione della coppia analitica; una scala temporale molto piů breve rispetto ai tempi necessari per l'articolazione delle parole, pertanto un livello non verbale. Si tratta di quella che si potrebbe chiamare "la musica e la danza" dell'azione terapeutica. La mia tesi č che includere questi domini addizionali possa migliorare la comprensione dell'azione terapeutica.

Angiogenesis inhibitors may enhance the effects of low dose (metronomic) chemotherapy. However, there is a wide range of novel angiogenesis inhibitors which must be tested in combinations with oral chemotherapy agents to assess the anti-endothelial and anti-cancer effects. This preliminary testing is most suited to high throughput in vitro models, rather than clinical trials. We aimed to establish an in vitro model and test the anti-endothelial and anti-cancer effects of the multi-kinase inhibitor sorafenib when used as a single agent and in combination with oral chemotherapy agents used at low concentrations. Micro-vascular endothelial cells and 3 cancer cell lines were utilised and an extended treatment strategy (96 h) was employed in order to mimic a continuous low dose anti-angiogenic chemotherapy regimen. Sorafenib significantly enhanced the anti-endothelial effect of low dose etoposide, paclitaxel and temozolomide. Sorafenib also significantly enhanced the anti-cancer effect of low dose etoposide, paclitaxel and temozolomide in SK-MEL-2 melanoma cells, producing an additive effect on inhibition of cell growth in all cases. These combinations appear to be the most promising for in vivo pre-clinical studies, with a view to testing in melanoma patients as a continuous dosing strategy, due to the in vitro additive inhibitory effect on growth seen in both endothelial and cancer cells.

Families with autosomal dominant frontotemporal dementia and amyotrophic lateral sclerosis (FTD/ALS) have previously been linked to a locus on chromosome 9p21. We describe the clinical phenotype and pathology of a large family with autosomal dominant FTD/ALS with nine affected members originating from Gwent in South Wales, UK. We also further refine the locus on chromosome 9p21 using a haplotype sharing approach and assess heterogeneity in 9p21 linked families. Within this family, affected individuals present with either FTD or ALS or both diseases simultaneously. In addition there was marked phenotypic variation including ataxia, Parkinsonism, psychosis and visuo-spatial cognitive deficits. The pathological features of the three cases described were consistent with type 2 FTD pathology, as previously reported in similar families. However, we also report distinctive cerebellar and glial pathology and a significant proportion of TDP-43 negative inclusions. No mutations in known genes for FTD or ALS were found. We identified a large 4.8-megabase haplotype on chromosome 9p21, which was shared by all affected family members. This haplotype overlaps and limits the previously reported FTD/ALS linkage region on chromosome 9p21. Sequencing of this region did not identify any evidence of a pathogenic exonic mutation. This suggests that the pathogenic change affects non-coding DNA and that the disease is caused by variation in gene or protein expression.

Objectives:To characterise the neuropathological phenotypes of two affected individuals from a family with an unusual clinical phenotype resembling motor neurone disease and dementia. Methods:Histological sections of cerebral cortex, basal ganglia, brain stem, cerebellum, and spinal cord were stained with haematoxylin-eosin, luxol fast blue, silver stains, anti-tau, anti-ubiquitin, anti-α-synuclein, and anti-neurofilament. Results:Numerous ubiquitin positive, tau and α-synuclein negative intraneuronal inclusions were present in the cerebral cortex (particularly within the dentate gyrus), cerebellar cortex, brain stem, and spinal cord. The cerebellar ubiquitinated inclusions were located in the proximal dendrite of the Purkinje cells. Loss of Purkinje cells and occasional silver and neurofilament positive axonal swellings (torpedoes) were also seen within the cerebellar cortex. The main difference between the two cases was the severity of the spinal cord involvement: no significant pathology was present within one, but obvious motor neurone disease within the other. Conclusions:The clinical and neuropathological findings in this family are best described as an example of familial motor neurone disease with dementia. Intraneuronal ubiquitin inclusions together with agyrophilic, neurofilament positive torpedoes were present within the cerebellar cortex, both previously unrecognised findings in this group of diseases.

Sotos syndrome is a childhood overgrowth syndrome characterized by a distinctive facial appearance, height and head circumference >97th percentile, advanced bone age, and developmental delay. Weaver syndrome is characterized by the same criteria but has its own distinctive facial gestalt. Recently, a 2.2-Mb chromosome 5q35 microdeletion, encompassing NSD1, was reported as the major cause of Sotos syndrome, with intragenic NSD1 mutations identified in a minority of cases. We evaluated 75 patients with childhood overgrowth, for intragenic mutations and large deletions of NSD1. The series was phenotypically scored into four groups, prior to the molecular analyses: the phenotype in group 1 (n=37) was typical of Sotos syndrome; the phenotype in group 2 (n=13) was Sotos-like but with some atypical features; patients in group 3 (n=7) had Weaver syndrome, and patients in group 4 (n=18) had an overgrowth condition that was neither Sotos nor Weaver syndrome. We detected three deletions and 32 mutations (13 frameshift, 8 nonsense, 2 splice-site, and 9 missense) that are likely to impair NSD1 functions. The truncating mutations were spread throughout NSD1, but there was evidence of clustering of missense mutations in highly conserved functional domains between exons 13 and 23. There was a strong correlation between presence of an NSD1 alteration and clinical phenotype, in that 28 of 37 (76%) patients in group 1 had NSD1 mutations or deletions, whereas none of the patients in group 4 had abnormalities of NSD1. Three patients with Weaver syndrome had NSD1 mutations, all between amino acids 2142 and 2184. We conclude that intragenic mutations of NSD1 are the major cause of Sotos syndrome and account for some Weaver syndrome cases but rarely occur in other childhood overgrowth phenotypes.

This is a reflection about my views on philosophy and art, and my approach to the latter. I also look into my personal history briefly connecting it with broader aspects of art history. The text is a personal reflection in an attempt to understand what I’m doing and why I do it.

Denna uppsats beskriver och analyserar mitt masterprojekt vid Konsthögskolan i Trondheim. Masterprojektet är en visualisering av sjukdomstillstånd och tillfrisknande. Avhandlingen beskriver processen för konstframställning, val av bilder, tekniker och arbete med utsällning. Konstprojektet diskuteras i termer av maner, hur man når en publiken i relation till val av konstteknik och urställningens design samt till konstnärernas budskap och i relation till skildring av sjukdomar och sjukdomar i konsthistorien. This thesis is describing and analysing my master project at the Art academy in Trondheim. The master project is a visualization of state of sickness and recovery. The thesis describes the process of art making, choice of images, techniques, and exhibit display. The art project is discussed in terms of the artist manner, the audience perception in relation to choices of art techniques and exhibit display as well as to the artists’ message, and in relation to depiction of disease and sickness in art history.
