Abstract
Risperidone is commonly used to treat different psychiatric disorders worldwide. Knowledge on dose–concentration relationships of risperidone treatment in children and adolescents with schizophrenia or other psychotic disorders is, however, scarce and no age-specific therapeutic ranges have been established yet. Multicenter data of a therapeutic drug monitoring service were analyzed to evaluate the relationship between risperidone dose and serum concentration of the active moiety (risperidone (RIS) plus its main metabolite 9-hydroxyrisperidone (9-OH-RIS)) in children and adolescents with psychotic disorders. Patient characteristics, doses, serum concentrations and therapeutic outcomes were assessed by standardized measures. The study also aimed to evaluate whether the therapeutic reference range for adults (20–60 ng/ml) is applicable for minors. In the 64 patients (aged 11–18 years) included, a positive correlation between daily dose and the active moiety (RISam) concentration was found (rs = 0.49, p = 0.001) with variation in dose explaining 24% (rs2 = 0.240) of the variability in serum concentrations. While the RISam concentration showed no difference, RIS as well 9-OH-RIS concentrations and the parent to metabolite ratio varied significantly in patients with co-medication of a CYP2D6 inhibitor. Patients with extrapyramidal symptoms (EPS) had on average higher RISam concentrations than patients without (p = 0.05). Considering EPS, the upper threshold of the therapeutic range of RISam was determined to be 33 ng/ml. A rough estimation method also indicated a possibly decreased lower limit of the preliminary therapeutic range in minors compared to adults. These preliminary data may contribute to the definition of a therapeutic window in children and adolescents with schizophrenic disorders treated with risperidone. TDM is recommended in this vulnerable population to prevent concentration-related adverse drug reactions.

Abstract
Clinical academia aims to bridge the gap between clinicians and scientists, by combining academic activity with clinical practice. The term 'clinical academics' generally refers to clinicians who have protected time within their job plans for undertaking academic activities. Engagement with academic activity by trainees is not only essential to fulfil necessary curriculum competencies, but also allows them to explore areas of interest outside of clinical practice and develop advanced academic skills. This article provides an overview of different routes into academic neurosurgery, and discusses the advantages and difficulties in pursuing this career path. It also covers the differences between postgraduate research degrees and explores the different job plan models available at consultant level. Academic neurosurgery is a rewarding career and opportunities should be made available to those who wish to explore it further. Developing academic careers may have a positive impact on wider workforce planning strategies and improve the delivery of high-quality evidence-based neurosurgical care.

Abstract
Abstract
BACKGROUND
Brain metastasis (BM) and leptomeningeal disease (LMD) are typified by a poor prognosis and are an area of unmet clinical need. Historically, patients with central nervous system (CNS) disease have been excluded from systemic therapy clinical trials, particularly with active/leptomeningeal disease. However, increasing prevalence of CNS metastasis is leading to greater interest in BM/LMD. We performed a descriptive analysis of clinical studies investigating BM/LMD management, published between Jan 2010 to Mar 2020.
METHODS
A comprehensive, customised search strategy was devised for 12 online bibliographic databases, using the following concepts: “clinical study”, “brain metastasis”, “leptomeningeal disease”, “intervention”, “patient-related outcome”. Double screening for inclusion/exclusion was performed on the Rayyan QCRI web application. Published abstracts were also screened for inclusion from ASCO, ESMO, SNO and EANO between 2015–2020. Following full text screening, conflicts were resolved by consensus and data were extracted using an online standardised tool. Data analysis and data visualisation were performed on the R statistical package.
RESULTS
Overall, 33118 published studies were double screened; 2632 full publications and 628 abstracts were included. Of these, 14.7% reported on unique interventional clinical trials (phase 2 = 267; phase 3 = 80). More than three times the number of clinical trials investigating systemic agents as the sole therapy for BM/LMD were published in Q1 2020 compared to the whole of 2010 (16 vs 5). 42.5% of clinical trials employed a form of local therapy (brain targeted radiotherapy or neurosurgery). Studies reported on patients with BM (n = 2738), LMD (n = 110) or both (n = 119). The majority of studies were performed in North America, Europe or East Asia (88.5% vs 11.5% rest of the world). The top 3 nations involved in published studies were the USA (n = 1155), China (n = 351) and Germany (n = 334). Network analysis demonstrated increasing links between countries. In line with expected BM prevalence, the main tumour sites studied were lung (23.4%), gastrointestinal (17.5%), breast (15%) and melanoma (12.5%). A rising trend of published BM/LMD studies over time was noted, with 83 observational studies/10 clinical trials in 2010 vs. 454 observational studies/80 clinical trials in 2019.
CONCLUSION
These findings demonstrate that over the last decade there has been a growth in BM/LMD research; likely reflecting an increasing disease prevalence, availability of novel and potentially CNS active agents, as well as more advanced local therapy modalities. BM/LMD clinical research is dominated by a few geographical regions and nations; however, there is an apparent shift to more international collaboration. This comprehensive mapping exercise will enable targeted systematic reviews of the existing evidence base on BM/LMD management.

Abstract
After COVID-19, some patients develop long-term symptoms. Whether such symptoms correlate with immune responses, and how long immunity persists, is not yet clear. This study focused on mild COVID-19 and investigated correlations of immunity with persistent symptoms and immune longevity. Persistent complications, including headache, concentration difficulties and loss of smell/taste, were reported by 51 of 83 (61%) participants and decreased over time to 28% one year after COVID-19. Specific IgA and IgG antibodies were detectable in 78% and 66% of participants, respectively, at a 12-month follow-up. Median antibody levels decreased by approximately 50% within the first 6 months but remained stable up to 12 months. Neutralizing antibodies could be found in 50% of participants; specific INFgamma-producing T-cells were present in two thirds one year after COVID-19. Activation-induced marker assays identified specific T-helper cells and central memory T-cells in 80% of participants at a 12-month follow-up. In correlative analyses, older age and a longer duration of the acute phase of COVID-19 were associated with higher humoral and T-cell responses. A weak correlation between long-term loss of taste/smell and low IgA levels was found at early time points. These data indicate a long-lasting immunological memory against SARS-CoV-2 after mild COVID-19.

Abstract
Background Conidiobolus spp. (mainly C. coronatus) are the causal agents of rhino-facial conidiobolomycosis, a limited soft tissue infection, which is essentially observed in immunocompetent individuals from tropical areas. Rare cases of invasive conidiobolomycosis due to C. coronatus or other species (C.incongruus, C.lamprauges) have been reported in immunocompromised patients. We report here the first case of invasive pulmonary fungal infection due to Conidiobolus pachyzygosporus in a Swiss patient with onco-haematologic malignancy. Case presentation A 71 year-old female was admitted in a Swiss hospital for induction chemotherapy of acute myeloid leukemia. A chest CT performed during the neutropenic phase identified three well-circumscribed lung lesions consistent with invasive fungal infection, along with a positive 1,3-beta-d-glucan assay in serum. A transbronchial biopsy of the lung lesions revealed large occasionally septate hyphae. A Conidiobolus spp. was detected by direct 18S rDNA in the tissue biopsy and subsequently identified at species level as C. pachyzygosporus by 28S rDNA sequencing. The infection was cured after isavuconazole therapy, recovery of the immune system and surgical resection of lung lesions. Conclusions This is the first description of C. pachyzygosporus as human pathogen and second case report of invasive conidiobolomycosis from a European country.

Abstract
One of the key challenges noted in the sustainable development goals for good health and wellbeing (SDGs 3) is both ambient and household air pollution. Household solid fuel combustion represents one of the biggest threat to human health in South Africa. This study helps to understand the impact of solid fuel burning in an indoor and ambient environment. Continuous monitoring of particulate matter (PM4) was carried out in two houses, one used coal as a primary source of energy, while the other did not. For solid fuel burning (SFB) house the winter PM4 average 24-h concentration ranges between 60.9 μg m-3 and 207.5 μg m-3 while at non-solid fuel burning (NSFB) house it ranges between 15.3 μg m-3 and 84.2 μg m-3. In both houses, the national ambient air quality standard (NAAQS) for PM2.5 (40 μg m-3) were exceeded during winter. The summer PM4 levels ranged between 17.4 μg m-3 and 36.6 μg m-3 in the solid fuel burning house and between 14.2 μg m-3 and 39.9 μg m-3 at the non-solid fuel-burning house. During mornings and evenings, indoor concentrations were higher than the outdoor; these periods coincide with the fuel-burning pattern in this community. In the mid-afternoon, the outdoor PM levels sometimes went higher than the indoor levels, perhaps as a result of the pollution from the power plants in the neighbourhood. Using the linear regression model, there were no significant correlations between indoor/outdoor PM4 concentrations during the winter, but there were good correlations for both houses during the summer. There was an observed difference in the thermal comfort at the SFB and NSFB. The temperature at SFB went below the World Health Organisation standard in winter and above during the summer while at NSFB, the temperature was managed within the standard in both seasons.

Abstract
BACKGROUND The frequent occurrence of medicine stockouts represents a significant obstacle to tuberculosis control in South Africa. Stockouts can lead to treatment alterations or interruptions, which can impact treatment outcomes. This study investigates the determinants and effects of TB drug stockouts and whether poorer districts are disproportionately affected. METHODS TB stockout data, health system indicators and TB treatment outcomes at the district level were extracted from the District Health Barometer for the years 2011, 2012 and 2013. Poverty terciles were constructed using the Census 2011 data to investigate whether stockouts and poor treatment outcomes were more prevalent in more impoverished districts. Fixed-effects regressions were used to estimate the effects of TB stockouts on TB treatment outcomes. RESULTS TB stockouts occurred in all provinces but varied across provinces and years. Regression analysis showed a significant association between district per capita income and stockouts: a 10% rise in income was associated with an 8.50% decline in stockout proportions. In terms of consequences, after controlling for unobserved time invariant heterogeneity between districts, a 10% rise in TB drug stockouts was found to lower the cure rate by 2.10% (p < 0.01) and the success rate by 1.42% (p < 0.01). These effects were found to be larger in poorer districts. CONCLUSIONS The unequal spread of TB drug stockouts adds to the socioeconomic inequality in TB outcomes. Not only are stockouts more prevalent in poorer parts of South Africa, they also have a more severe impact on TB treatment outcomes in poorer districts. This suggests that efforts to cut back TB drug stockouts would not only improve TB treatment outcomes on average, they are also likely to improve equity because a disproportionate share of this burden is currently borne by the poorer districts.

Abstract
Faced with the threat of "Day Zero", when it was feared that Cape Town's taps could run dry, consumers reduced household water usage from 540 to 280 L per household per day over the 36 months between January 2015 and January 2018. This paper describes the events that prompted this reduction. We look at how changes in water use were affected by official announcements and by public engagement with this news via the social media activity and internet searches. We analysed the water usage of a subset of middle to high income households where smart hot and cold water meters were installed. For hot water usage patterns we compared meter readings with that in another area unaffected by the drought. We further map our cold water smart meter readings against that of the City of Cape Town's municipal data for domestic freestanding households - a sample of more than 400,000 households. We found that the introduction of Level 5 restrictions had a perverse effect on consumption, possibly due to confusing messages. The most dramatic change in behaviour appears to have been instigated by a media storm and consequent user panic after the release of the City's Critical Water Shortages Disaster Plan in October 2017. However, contradictory communication from national and provincial government eroded some of this gain. The paper concludes with recommendations for demand management in a similar future scenario.

Abstract
Objective: To compare the availability, affordability and acceptability of two non-governmental organisation (NGO) led human immunodeficiency virus (HIV) testing service (HTS) modalities (mobile and stand-alone) with HTS at a public primary health care facility. Methods: Adult participants who self-referred for HIV testing were enrolled as they exited the HTS modalities. Data collection using an electronic questionnaire took place between November 2014 and February 2015. Logistic regression analysis was used to assess differences in the participants' demographic characteristics and the availability, affordability and acceptability of HTS between modalities. Results: There were 130 participants included in the study. Irrespective of modality, most participants walked to the service provider, had a travel time of <30 min and reported no costs. Participants were less likely to report waiting times of ⩾30 min compared to <15 min at the mobile modality compared to the public facility (aOR < 0.001, 95%CI < 0.001-0.03). Conclusion: Irrespective of modality, HIV testing services were available and affordable in our study. Waiting times were significantly higher at the public facility compared to the NGO modalities. As South Africa moves toward achieving the first UNAIDS target, it is essential not only to make HTS available and affordable, but also to ensure that these services are acceptable, especially to those who have never been tested before.

Abstract
Drivers of and barriers to testing are not well understood for those who have never been tested previously and now self-initiate at a community-based human immuno-deficiency virus (HIV) testing service (CB-HTS). This descriptive study enrolled 229 first-time testers. Participants completed an electronic questionnaire. The majority reported fear and (non) accessibility of HTS as barriers to testing (40% and 24%, respectively). Wanting 'to know my status' and the immediate opportunity to test were reported as drivers of testing (41% and 35%, respectively). Addressing fear of testing and providing an easily accessible opportunity to test may go some way to encouraging those previously untested individuals to test.

Abstract
Human γδ T cells are innate-like T cells which are able to kill a broad range of tumour cells and thus may have potential for cancer immunotherapy. The activating receptor natural killer group 2 member D (NKG2D) plays a key role in regulating immune responses driven by γδ T cells. Here, we explored whether recombinant immunoligands consisting of a CD20 single-chain fragment variable (scFv) linked to a NKG2D ligand, either MHC class I chain-related protein A (MICA) or UL16 binding protein 2 (ULBP2), could be employed to engage γδ T cells for tumour cell killing. The two immunoligands, designated MICA:7D8 and ULBP2:7D8, respectively, enhanced cytotoxicity of ex vivo-expanded γδ T cells against CD20-positive lymphoma cells. Both Vδ1 and Vδ2 γδ T cells were triggered by MICA:7D8 or ULBP2:7D8. Killing of CD20-negative tumour cells was not induced by the immunoligands, indicating their antigen specificity. MICA:7D8 and ULBP2:7D8 acted in a dose-dependent manner and induced cytotoxicity at nanomolar concentrations. Importantly, chronic lymphocytic leukaemia (CLL) cells isolated from patients were sensitized by the two immunoligands for γδ T cell cytotoxicity. In a combination approach, the immunoligands were combined with bromohydrin pyrophosphate (BrHPP), an agonist for Vδ2 γδ T cells, which further enhanced the efficacy in target cell killing. Thus, employing tumour-directed recombinant immunoligands which engage NKG2D may represent an attractive strategy to enhance antitumour cytotoxicity of γδ T cells.

Abstract
SETTING Eight communities with high tuberculosis (TB) prevalence, Western Cape, South Africa. OBJECTIVE To identify sex differences in TB health-seeking behaviour and diagnosis in primary health care facilities and how this influences TB diagnosis. DESIGN We used data from a prevalence survey among 30,017 adults conducted in 2010 as part of the Zambia, South Africa Tuberculosis and AIDS Reduction (ZAMSTAR) trial. RESULTS A total of 1670 (5.4%) adults indicated they had a cough of ⩾2 weeks, 950 (56.9%) of whom were women. Women were less likely to report a cough of ⩾2 weeks (5.1% vs. 6.4%, P < 0.001), but were more likely to seek care for their cough (32.6% vs. 26.9%, P = 0.012). Of all adults who sought care, 403 (80.0%) sought care for their cough at a primary health care (PHC) facility (79.0% women vs. 81.4% men, P = 0.511). Women were less likely to be asked for a sputum sample at the PHC facility (63.3% vs. 77.2%, P = 0.003) and less likely to have a positive sputum result (12.6% vs. 20.7%, P = 0.023). CONCLUSION The attainment of sex equity in the provision of TB health services requires adherence to testing protocols. Everyone, irrespective of sex, who seeks care for a cough of ⩾2 weeks should be tested.

Abstract
To address uncertainty of whether clinical stage groupings (cTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for clinically staged patients from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 22,123 clinically staged patients, 8,156 had squamous cell carcinoma, 13,814 adenocarcinoma, 116 adenosquamous carcinoma, and 37 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (18.5-25 mg/kg2 , 47%), little weight loss (2.4 ± 7.8 kg), 0-1 ECOG performance status (67%), and history of smoking (67%). Cancers were cT1 (12%), cT2 (22%), cT3 (56%), cN0 (44%), cM0 (95%), and cG2-G3 (89%); most involved the distal esophagus (73%). Non-risk-adjusted survival for squamous cell carcinoma was not distinctive for early cT or cN; for adenocarcinoma, it was distinctive for early versus advanced cT and for cN0 versus cN+. Patients with early cancers had worse survival and those with advanced cancers better survival than expected from equivalent pathologic categories based on prior WECC pathologic data. Thus, clinical and pathologic categories do not share prognostic implications. This makes clinically based treatment decisions difficult and pre-treatment prognostication inaccurate. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient characteristics, cancer categories, and treatment characteristics and should direct 9th edition data collection.

Abstract
We report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for patients with pathologically staged cancer of the esophagus and esophagogastric junction after resection or ablation with no preoperative therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted de-identified data using standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 13,300 patients, 5,631 had squamous cell carcinoma, 7,558 adenocarcinoma, 85 adenosquamous carcinoma, and 26 undifferentiated carcinoma. Patients were older (62 years) men (80%) with normal body mass index (51%), little weight loss (1.8 kg), 0-2 ECOG performance status (83%), and a history of smoking (70%). Cancers were pT1 (24%), pT2 (15%), pT3 (50%), pN0 (52%), pM0 (93%), and pG2-G3 (78%); most involved distal esophagus (71%). Non-risk-adjusted survival for both squamous cell carcinoma and adenocarcinoma was monotonic and distinctive across pTNM. Survival was more distinctive for adenocarcinoma than squamous cell carcinoma when pT was ordered by pN. Survival for pTis-1 adenocarcinoma was better than for squamous cell carcinoma, although monotonic and distinctive for both. WECC pathologic staging data is improved over that of the 7th edition, with more patients studied and patient and cancer variables collected. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics, and should direct 9th edition data collection. However, the role of pure pathologic staging as the principal point of reference for esophageal cancer staging is waning.

Abstract
To address uncertainty of whether pathologic stage groupings after neoadjuvant therapy (ypTNM) for esophageal cancer share prognostic implications with pathologic groupings after esophagectomy alone (pTNM), we report data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for pathologically staged cancers after neoadjuvant therapy from the Worldwide Esophageal Cancer Collaboration (WECC). Thirty-three institutions from six continents submitted data using variables with standard definitions: demographics, comorbidities, clinical cancer categories, and all-cause mortality from first management decision. Of 7,773 pathologically staged neoadjuvant patients, 2,045 had squamous cell carcinoma, 5,686 adenocarcinoma, 31 adenosquamous carcinoma, and 11 undifferentiated carcinoma. Patients were older (61 years) men (83%) with normal (40%) or overweight (35%) body mass index, 0-1 Eastern Cooperative Oncology Group performance status (96%), and a history of smoking (69%). Cancers were ypT0 (20%), ypT1 (13%), ypT2 (18%), ypT3 (44%), ypN0 (55%), ypM0 (94%), and G2-G3 (72%); most involved the distal esophagus (80%). Non-risk-adjusted survival for yp categories was unequally depressed, more for earlier categories than later, compared with equivalent categories from prior WECC data for esophagectomy-alone patients. Thus, survival of patients with ypT0-2N0M0 cancers was intermediate and similar regardless of ypT; survival for ypN+ cancers was poor. Because prognoses for ypTNM and pTNM categories are dissimilar, prognostication should be based on separate ypTNM categories and groupings. These data will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics and should direct 9th edition data collection.

Abstract
In this work we present a centrifugal microfluidic system enabling highly efficient collective trapping and alignment of particles such as microbeads and cells, their multi-colour fluorescent detection and subsequent manipulation by optical tweezers. We demonstrate array-based capture and imaging followed by "cherry-picking" of individual particles, first for fluorescently labelled polystyrene (PS) beads and then for cells. Different cell lines are discriminated based on intracellular as well as surface-based markers.

Abstract
We present a comprehensive overview of particulate air quality across the five major metropolitan areas of South Africa (Cape Town, Bloemfontein, Johannesburg and Tshwane (Gauteng Province), the Industrial Highveld Air Quality Priority Area (HVAPA), and Durban), based on a decadal (1 January 2000 to 31 December 2009) aerosol climatology from multiple satellite platforms and detailed analysis of ground-based data from 19 sites throughout Gauteng Province. Satellite analysis was based on aerosol optical depth (AOD) from MODIS Aqua and Terra (550 nm) and MISR (555 nm) platforms, Ångström Exponent (α) from MODIS Aqua (550/865 nm) and Terra (470/660 nm), ultraviolet aerosol index (UVAI) from TOMS, and results from the Goddard Ozone Chemistry Aerosol Radiation and Transport (GOCART) model. At continentally influenced sites, AOD, α, and UVAI reach maxima (0.12-0.20, 1.0-1.8, and 1.0-1.2, respectively) during austral spring (September-October), coinciding with a period of enhanced dust generation and the maximum integrated intensity of close-proximity and subtropical fires identified by MODIS Fire Information for Resource Management System (FIRMS). Minima in AOD, α, and UVAI occur during winter. Results from ground monitoring indicate that low-income township sites experience by far the worst particulate air quality in South Africa, with seasonally averaged PM10 concentrations as much as 136 % higher in townships that in industrial areas. We report poor agreement between satellite and ground aerosol measurements, with maximum surface aerosol concentrations coinciding with minima in AOD, α, and UVAI. This result suggests that remotely sensed data are not an appropriate surrogate for ground air quality in metropolitan South Africa.

Abstract
Despite new treatment modalities, the clinical outcome in a substantial number of patients with multiple myeloma (MM) has yet to be improved. Antibody-based targeted therapies for myeloma patients could make use of the HM1.24 antigen (CD317), a surface molecule overexpressed on malignant plasma cells and efficiently internalized. Here, a novel immunotoxin, HM1.24-ETA', is described. HM1.24-ETA' was generated by genetic fusion of a CD317-specific single-chain Fv (scFv) antibody and a truncated variant of Pseudomonas aeruginosa exotoxin A (ETA'). HM1.24-ETA' inhibited growth of interleukin 6 (IL-6)-dependent and -independent myeloma cell lines. Half-maximal growth inhibition was observed at concentrations as low as 0.3 nM. Target cell killing occurred via induction of apoptosis and was unaffected in co-culture experiments with bone marrow stromal cells. HM1.24-ETA' efficiently triggered apoptosis of freshly isolated/cryopreserved cells of patients with plasma cell leukemia and MM and was active in a preclinical severe combined immunodeficiency (SCID) mouse xenograft model. Importantly, HM1.24-ETA' was not cytotoxic against CD317-positive cells from healthy tissue (monocytes, human umbilical vein endothelial cells). These results indicate that CD317 may represent a promising target structure for specific and efficient immunotoxin therapy for patients with plasma cell tumors.

Abstract
From May to July 2011 [corrected] the world's largest outbreak of hemolytic uremic syndrome (HUS) occurred in northern Germany with dramatic consequences for the population, the health care system and the food industry. In the following we examine the detection of the outbreak, epidemic management and related public communication aspects based on scientific publications, media reports as well as own and new data analyses. The subsequent 17 recommendations concern issues such as participation in and implementation of existing and new surveillance systems particularly with respect to physicians, broad application of finely tuned microbiological typing, improved personnel capacity and crisis management structures within the public health service and evidence-based communication by administrations and scientific associations. Outbreaks of similar dimensions can inevitably occur again and result in costs which will far exceed investments needed for early detection and control. This societal balance should be taken into account in spite of limited resources in the public health sector.

Abstract
Re-introduction of rare species to parts of their historical range is becoming increasingly important as a conservation strategy. Telfair's Skinks (Leiolopisma telfairii), once widespread on Mauritius, were until recently found only on Round Island. There it is vulnerable to stochastic events, including the introduction of alien predators that may either prey upon it or compete for food resources. Consequently, skinks have been introduced to Ile aux Aigrettes, another small Mauritian island that has been cleared of rats. However, the island has been invaded by Asian Musk Shrews (Suncus murinus), a commensal species spread by man well beyond its natural Asian range. Our aim was to use next-generation sequencing to analyse the diets of the shrews and skinks to look for niche competition. DNA was extracted from skink faeces and from the stomach contents of shrews. Application of shrew- and skink-specific primers revealed no mutual predation. The DNA was then amplified using general invertebrate primers with tags to identify individual predators, and then sequenced by 454 pyrosequencing. 119 prey MOTUs (molecular taxonomic units) were isolated, although none could be identified to species. Seeding of cladograms with known sequences allowed higher taxonomic assignments in some cases. Although most MOTUs were not shared by shrews and skinks, Pianka's niche overlap test showed significant prey overlap, suggesting potentially strong competition where food resources are limited. These results suggest that removal of the shrews from the island should remain a priority.

Abstract
Mouse models of multiple myeloma (MM) are basic tools for translational research and play a fundamental role in the development of new therapeutics against plasma cell malignancies. All available models, including transplantable murine tumors in syngenic mice, xenografts of established human cell lines in immunocompromised mice and transgenic models that mirror specific steps of MM pathogenesis, have demonstrated some weaknesses in predicting clinical results, particularly for new drugs targeting the human bone marrow microenvironment (huBMM). The recent interest to models recapitulating the in vivo growth of primary MM cells in a human (SCID-hu) or humanized (SCID-synth-hu) host recipient has provided powerful platforms for the investigation of new compounds targeting MM and/or its huBMM. Here, we review and discuss strengths and weaknesses of the key in vivo models that are currently utilized in the MM preclinical investigation.

Abstract
Polymorphism of the human papillomavirus type 16 (HPV-16) genome has been reported to occur within the noncoding regulatory long control region (LCR) and in the E7 and L1 genes. The current study focuses on the HPV-16 E6 oncogene which interacts with the antioncogenic regulator p53. Seventy-eight HPV-16-positive DNA samples derived from cervical carcinomas were screened for the presence of polymorphism in the HPV-16 E6 gene by polymerase chain reaction (PCR) linked single stranded conformational polymorphism (SSCP) analysis. Nine DNA samples had heterozygous mutations within the same region of the E6 gene 3' terminus; T to C transitions at HPV-16 position 511 (silent) and one of the nine also had a 513 mutation (Met to Thr). These mutations correlated with the clinical aggressiveness of the tumor, suggesting that the presence of these mutations may be due to genomic instability of advanced cervical carcinoma.

Abstract
INTRODUCTION Information about therapeutic serum levels of fluoxetine (FLX) and its major metabolite norfluoxetine (NORFLX) in children and adolescents is scarce. METHODS Therapeutic drug monitoring (TDM) of FLX was routinely performed in 71 subjects treated for a major depressive disorder (MDD) (10-60 mg/d FLX, median: 20 mg/d). Correlations between serum concentration and dosage, age, gender, smoking habits and adverse events were analysed. RESULTS Serum concentrations of the active moiety (FLX + NORFLX) ranged from 21 to 613 ng/mL (mean concentration of 213 ± 118 ng/mL, median: 185 ng/mL). High inter-individual variability in serum concentrations of the active moiety of FLX at each dosage level was observed and no relationship between serum concentration and clinical outcome was found. Apart from smoking, none of the factors tested had a significant eff ect on the serum concentration. DISCUSSION It was shown that serum concentrations of the active moiety of FLX in children and adolescents seem to be similar to those in adults, with a high level of inter-individual variation. The proportion of patients who showed benefits from treatment with a dose of 20 mg/d FLX was high.

Abstract
A 14-year-old girl with suicidal ideation was presented to the paediatric hospital about 2 h after ingestion of 21 long-acting methylphenidate (MPH) 54-mg tablets (1,134 mg Concerta(®)). At admission signs of sympathomimetic syndrome were observed like agitation, visual hallucinations, slight hypertension, and sinus tachycardia. Treatment included prevention of absorption (30 g activated charcoal orally) and careful observation related to the overstimulation of the sympathic system. Despite the intake of charcoal, the serum concentrations of MPH were 107 and 93 ng/ml 2.5 and 22 h after ingestion of MPH tablets. No support of vital functions was necessary. The girl made a full recovery and was discharged after 3 days of care at the paediatric clinic and referred to the child and adolescent psychiatric department. Exposure to a huge overdose of long-acting MPH exhibited acute sympathomimetic toxicity but no life-threatening symptoms in this patient. Thus this case report suggests that patients intoxicated with high dose long-acting MPH formulations can recover without sequelae when managed properly.
