Abstract
OBJECTIVES (1) Determine 1-year period prevalence of suicidal ideation, suicide attempt, and completed suicide among patients newly diagnosed with a first occurrence of head and neck cancer (HNC). (2) Characterize stability and trajectory of suicidal ideation over the year following cancer diagnosis. (3) Identify patients at risk of suicidal ideation. STUDY DESIGN Prospective longitudinal study with 1-year follow-up. SETTING Three university-affiliated outpatient departments of otolaryngology-head and neck surgery. SUBJECTS AND METHODS The study comprised a representative sample of 223 consecutive patients who were newly diagnosed (<2 weeks) with a first occurrence of primary HNC, were ≥18 years old and able to consent, and had a Karnofsky Performance Scale score ≥60. Patients completed the Beck Scale for Suicidal Ideation and Structured Clinical Interview for DSM-IV-TR Axis I Disorders. RESULTS Sixteen percent (15.7%) of patients with HNC were suicidal <1 year from diagnosis, with point prevalences of 8.1% <2 weeks, 14.8% at 3 months, 9.4% at 6 months, and 10.4% at 12 months; 0.4% committed suicide within 3 months, and 0.9% attempted suicide. An a priori comprehensive conceptual model revealed 2 predictors of 1-year period prevalence of suicidal ideation in HNC: psychiatric history ( P = .017, β = 2.1, 95% CI = 0.4-3.8) and coping with the diagnosis by using substances (alcohol/drugs; P = .008, β = 0.61, 95% CI = 0.16-1.06). All other predictors, including medical predictors, were nonsignificant. A clinical suicide risk assessment revealed low risk among 71.4% and medium to high risk among 28.6%. CONCLUSION Suicide prevention strategies are clearly needed as part of routine clinical care in head and neck oncology, as well as their integration into clinical practice guidelines for HNC.

Abstract
OBJECTIVE To undertake an analysis of National Child Measurement Programme (NCMP) data to quantify the obesity prevalence gap over time between children in primary schools in the most and least deprived areas of Doncaster. STUDY DESIGN The research design for this study was retrospective quantitative analysis of secondary data. METHODS The study undertook secondary analysis of NCMP data on obesity prevalence in children in Reception Year and Year 6 in primary schools in Doncaster for the period 2006-2007 to 2014-2015. Data were combined into three 3-year periods (2006-2007 to 2008-2009; 2009-2010 to 2011-2012; and 2012-2013 to 2014-2015), and schools were grouped by deprivation based on the national Indices of Multiple Deprivation 2015. Analysis was undertaken to assess whether there is a difference in obesity prevalence for Reception Year and Year 6 children in schools in the most deprived areas compared with the least deprived (prevalence gap), over time. RESULTS The difference in obesity prevalence between children attending schools in the most and least deprived areas has increased over time. For Reception Year children, the prevalence gap has widened from a difference of 1.01% higher in the most deprived schools in 2006-2007 to 2008-2009 to 3.64% higher in 2012-2013 to 2014-2015. In the same time periods, for Year 6 children, the obesity prevalence gap has also increased over time from 2.82% to 5.08%. CONCLUSIONS There is inequality in relation to obesity in primary school children in Doncaster with those in schools in the most deprived areas carrying the greatest burden. Research is needed to understand why the plateau seen nationally is not reaching the most deprived children.

Abstract
The capecitabine and temozolomide (CAPTEM) regimen is active in the treatment of metastatic pancreatic neuroendocrine tumors (pNETs), with response rates ranging from 30 to 70%. Small retrospective studies suggest that O(6)-methylguanine DNA methyltransferase (MGMT) deficiency predicts response to temozolomide. High tumor proliferative activity is also commonly perceived as a significant predictor of response to cytotoxic chemotherapy. It is unclear whether chromosomal instability (CIN), which correlates with alternative lengthening of telomeres (ALT), is a predictive factor. In this study, we evaluated 143 patients with advanced pNET who underwent treatment with CAPTEM for radiographic and biochemical response. MGMT expression (n=52), grade (n=128) and ALT activation (n=46) were investigated as potential predictive biomarkers. Treatment with CAPTEM was associated with an overall response rate (ORR) of 54% by RECIST 1.1. Response to CAPTEM was not influenced by MGMT expression, proliferative activity or ALT pathway activation. Based on these results, no biomarker-driven selection criteria for use of the CAPTEM regimen can be recommended at this time.

Abstract
Thrombocytopenia is commonly encountered in veterinary oncology. Currently, there are no standard guidelines regarding the administration of chemotherapy to the patients with thrombocytopenia. This observational epidemiological cohort study aimed to determine whether thrombocytopenic dogs were at increased risk of gastrointestinal adverse effects (vomiting, diarrhoea, inappetence) or haemorrhage following administration of standard doses of chemotherapy. The adverse effects following 77 prospectively identified episodes of thrombocytopenia (platelet count, <200 000 µL-1 ) were compared with the adverse effects experienced in a retrospective cohort (platelet count >200 000 µL-1 ), and evaluated by statistical analysis. Overall, there was no statistically significant difference in the incidence of gastrointestinal adverse effects or haemorrhage between thrombocytopenic and control dogs. The control group of dogs with lymphoma were statistically more likely to experience vomiting as an adverse effect of chemotherapy (P = 0.028). The results presented here showed no evidence for an increased risk of gastrointestinal adverse effects or haemorrhage in thrombocytopenic dogs after receiving standard doses of chemotherapy.

Abstract
Next-generation sequencing (NGS) has revolutionized the field of genomics and improved our understanding of cancer biology. Advances have been achieved by sequencing tumor DNA and using matched normal DNA to filter out germ line variants to identify cancer-specific changes. The identification of high incidences of activating mutations in head and neck squamous cell carcinoma (HNSCC) amenable to drug targeting has been made, with clear distinctions between the mutational profile of HPV-positive and HPV-negative tumors. This wealth of new understanding undoubtedly ameliorates our understanding of HNSCC cancer biology and elucidates clear targets for drug targeting which will guide future personalized medicine.

Abstract
Despite the frequent occurrence of head and neck cancer (HNC) disfigurement, little is known about its psychosocial impact on patients. This study aimed to understand the lived experience of disfigurement in HNC and explore what patients considered to be its influences. Fourteen disfigured HNC patients participated in a 45-to-120-minute in-depth, semistructured interview, which was analyzed qualitatively using interpretive phenomenology. A majority of participants (64 percent) were considered to be at an advanced cancer stage (stage III or stage IV). Patients' experiences revolved around the concept of a ruptured self-image (a discontinuity in sense of self). Forces triggering this ruptured self-image created a sense of "embodied angst", in which disfigurement served as a constant reminder of the patient's cancer and associated foundational malaise. Other influences fostered a sense of normalcy, balance, and acceptance. Participants oscillated between these two states as they grew to accept their disfigurement. This study's findings could guide supportive interventions aimed at helping patients face head and neck surgery.

Abstract
Intravenous amphotericin B is a key component of the antifungal therapy for cryptococcal meningitis recommended in South African and international guidelines. Unfortunately, its use is associated with significant toxicity including deterioration in renal function, electrolyte disturbance, anaemia and infusion reactions. Chemical phlebitis is common following administration via peripheral cannulae. This can be complicated by bacterial infection, resulting in localised cellulitis or bacterial sepsis. Here we describe two patients with cryptococcal meningitis who developed methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia during, or shortly after treatment with amphotericin B. These cases illustrate the dangers of line-related sepsis in hospitalised individuals and some of the difficulties encountered during treatment of this condition.

Abstract
BACKGROUND This study was performed to establish age-related serum reference intervals for procollagen type I N-propeptide (P1NP) and type I collagen C-telopeptide (CTx) in the Australian population. METHODS Fasting sera from 1143 males (mean age 60 years; range 20-97 years) and 1246 females (mean age 53 years; range 20-93 years) who participated in the Geelong Osteoporosis Study were analysed for CTx and P1NP using the automated Roche Modular Analytics E170 analyser. RESULTS Optimal age-related reference intervals were based on the central 90% of the distribution. The male CTx reference interval was divided into three age groups. For men aged 25 to 40 years, the interval was 170-600 ng/L; 40 to 60 years, the interval was 130-600 ng/L; and for men aged greater 60 years the interval was 100-600 ng/L. For P1NP the male reference interval was 15-80 μg/L for men aged between 25 to 70 years. In men greater than 70 years of age values were higher possibly due to increased bone turnover. High values are frequently seen for both CTx and P1NP in males aged younger than 25 years. This is probably due to bone growth that is not completely finalised. The female CTx reference interval was divided into four age groups. For women aged less than 30 years, the interval was 150-800 ng/L; 30-39 years, the interval was 100-700 ng/L; 40-49 years, the interval was 100-600 ng/L; and for women aged 50 years or more the interval was 100-700 ng/L. The female P1NP reference interval was divided into four age groups. For women aged less than 30 years, the interval was 25-90 μg/L; 30-39 years, the interval was 15-80 μg/L; 40-49 years, the interval was 15-60 μg/L; and for women aged 50-69 years the interval was 15-75 μg/L. In women greater than 70 years of age values were higher possibly due to increased bone turnover. CONCLUSION Values obtained from this large study provide sound age-related reference intervals for serum P1NP and CTx values in the Australian population.

Abstract
A multidisciplinary model is a useful approach in the management of hepatocellular carcinoma (HCC) to coordinate, individualize, and optimize care. The HCC Multidisciplinary Team (MDT) at Temple University Hospital was established in 2008 and comprises hepatologists, interventional radiologists, transplant surgeons, oncologists, residents, midlevel providers, and support staff. Patients may be enrolled by referral from (1) oncologists at Temple, (2) the hepatitis screening clinic recently established at Temple and staffed by hepatology residents, or (3) community practices. MDT conferences are held weekly, during which cases are discussed (based on medical history, interpretation of images, and laboratory analyses) and treatment plans are formulated. The Temple treatment algorithm follows current standards of care, guided by tumor volume and morphology, but the novel multidisciplinary interaction challenges members to tailor therapy to achieve the best possible outcomes. Patients with a solitary lesion ≤ 2 cm may receive no treatment until eligible for transplantation or locoregional therapy or resection, with imaging every 3 to 6 months to monitor tumor progression. In patients with tumors > 2 cm and ≤ 5 cm, microwave ablation therapy is used if lesions are discrete and accessible. Conventional transarterial chemoembolization (TACE) or drug-eluting bead TACE (DEB-TACE) or yttrium-90 microspheres are utilized in multifocal disease. Patients with lesions > 5 cm are candidates for TACE for downstaging the tumor. Sorafenib is typically reserved for unresectable lesions between 2 cm and 5 cm. Frequently, we administer sorafenib continuously and in combination with DEB-TACE. In our experience, sorafenib does not produce effects on the tumor vasculature or blood flow that would impair the efficacy of DEB-TACE. The literature documents improved outcomes in HCC and other cancers associated with the introduction of multidisciplinary care. The role and organization of the MDT is influenced by team culture, expertise, and process, as well as institutional and larger environmental contexts.
