RESUMO

PURPOSE: Patients with cancer often experience nutritional challenges and are vulnerable to muscle mass loss. While substantial research is directed towards understanding how nutritional interventions affect clinical outcomes, insights into patients' personal experiences during these trials remain limited. This qualitative study aimed to gain a deeper understanding of how participation in the Protein Recommendations to Increase Muscle (PRIMe) trial affected patients' relationships with food. METHODS: A subset of patients who completed a minimum of one follow-up visit in the PRIMe trial participated in a semi-structured interview about their experience implementing dietary modifications to increase protein intake. Data from 26 patients with a recent diagnosis of stage II-IV colorectal cancer (non-cachectic) were included. Interviews were audio recorded, transcribed verbatim, and qualitative content analysis was applied. RESULTS: Most patients were male (65.4%) with stage II or III (69.2%) colorectal cancer and were a mean age of 57 ± 10 years. Five key themes emerged to provide a deeper understanding of patients' relationship with food after the PRIMe trial: (1) new positive perspectives on nutrition and coping with a cancer diagnosis; (2) embracing a comprehensive approach to food and nutrition; (3) facilitators promoting adherence to the intervention; (4) barriers challenging adherence to the intervention; and (5) shaping future dietary intake. CONCLUSION: This qualitative study explored the emotional and psychological effects of a clinical nutrition trial on patients, focusing on their relationship with food. It underscored the trial's comprehensive intervention and its enduring influence on patients, extending beyond the immediate intervention phase. The role of current perspectives, motivation, and knowledge acquisition on ability to adhere to dietary changes to increase protein intake were emphasized by patients and are key considerations for both clinicians and researchers.

RESUMO

OBJECTIVE: Although the significance of the general factor of psychopathology (p) is being increasingly recognized, it remains unclear how to best operationalize and measure p. To test variations in the operationalizations of p and make practical recommendations for its assessment, we compared p-factor scores derived from four models. METHODS: We compared p scores derived from principal axis (Model 1), hierarchical factor (Model 2), and bifactor (Model 3) analyses, plus a Total Problem score (sum of unit-weighted ratings of all problem items; Model 4) for parent- and self-rated youth psychopathology from 24 societies. Separately for each sample, we fitted the models to parent-ratings on the Child Behavior Checklist for Ages 6-18 (CBCL/6-18) and self-ratings on the Youth Self-Report (YSR) for 25,643 11-18-year-olds. Separately for each sample, we computed correlations between p-scores obtained for each pair of models, cross-informant correlations between p-scores for each model, and Q-correlations between mean item x p-score correlations for each pair of models. RESULTS: Results were similar for all models, as indicated by correlations of .973-.994 between p-scores for Models 1-4, plus similar cross-informant correlations between CBCL/6-18 and YSR Model 1-4 p-scores. Item x p correlations had similar rank orders between Models 1-4, as indicated by Q correlations of .957-.993. CONCLUSIONS: The similar results obtained for Models 1-4 argue for using the simplest model - the unit-weighted Total Problem score - to measure p for clinical and research assessment of youth psychopathology. Practical methods for measuring p may advance the field toward transdiagnostic patterns of problems.

RESUMO

Hypoxia-mediated red blood cell (RBC) sickling is central to the pathophysiology of sickle cell disease (SCD). The signalling nucleoside adenosine is thought to play a significant role in this process. This study investigated expression of the erythrocyte type 1 equilibrative nucleoside transporter (ENT1), a key regulator of plasma adenosine, in adult patients with SCD and carriers of sickle cell trait (SCT). Relative quantitative expression analysis of erythrocyte ENT1 was carried out by Western blot and flow cytometry. Patients with SCD with steady state conditions, either with SS or SC genotype, untreated or under hydroxycarbamide (HC) treatment, exhibited a relatively high variability of erythrocyte ENT1, but with levels not significantly different from normal controls. Most strikingly, expression of erythrocyte ENT1 was found to be significantly decreased in patients with SCD undergoing painful vaso-occlusive episode and, unexpectedly, also in healthy SCT carriers. Promoting hypoxia-induced adenosine signalling, the reduced expression of erythrocyte ENT1 might contribute to the pathophysiology of SCD and to the susceptibility of SCT individuals to altitude hypoxia or exercise to exhaustion.

RESUMO

BACKGROUND: An antibody directed against a high-prevalence red blood cell (RBC) antigen was detected in a 67-year-old female patient of North African ancestry with a history of a single pregnancy and blood transfusion. So far, the specificity of the proband's alloantibody remained unknown in our immunohematology reference laboratory. STUDY DESIGN AND METHODS: Whole-exome sequencing (WES) was performed on the proband's DNA. The reactivity to the SLC29A1-encoded ENT1 adenosine transporter was investigated by flow cytometry analyses of ENT1-expressing HEK293 cells, and RBCs from Augustine-typed individuals. Erythrocyte protein expression level, nucleoside-binding capacity, and molecular structure of the proband's ENT1 variant were further explored by western blot, flow cytometry, and molecular dynamics calculations, respectively. RESULTS: A missense variant was identified in the SLC29A1 gene, which encodes the Augustine blood group system. It arises from homozygosity for a rare c.242A > G missense mutation that results in a nonsynonymous p.Asn81Ser substitution within the large extracellular loop of ENT1. Flow cytometry analyses demonstrated that the proband's antibody was reactive against HEK-293 cells transfected with control but not proband's SLC29A1 cDNA. Consistent with this finding, proband's antibody was found to be reactive with At(a-) (AUG:-2), but not AUG:-1 (null phenotype) RBCs. Data from structural analysis further supported that the proband's p.Asn81Ser variation does not alter ENT1 binding of its specific inhibitor NBMPR. CONCLUSION: Our study provides evidence for a novel high-prevalence antigen, AUG4 (also called ATAM after the proband's name) in the Augustine blood group system, encoded by the rare SLC29A1 variant allele AUG*04 (c.242A > G, p.Asn81Ser).

RESUMO

OBJECTIVES: To examine healthcare utilisation patterns in a sample of young people with self-reported experiences of self-harm and/or suicidal behaviours. METHODS: A national survey examining mental health in a nationally representative sample of young Australians aged 12-17 years, linked to routinely collected healthcare and dispensing data. For respondents that self-reported experience of self-harm, suicidal ideation, suicidal plan and/or suicide attempt, we assessed attendance at a Medicare Benefits Scheme (MBS) subsidised MH service or non-MH general practitioner (GP) attendance at three time periods: 1) ever, 2) in the 12 months prior to completing the survey and 3) after completing the survey until 31 Dec 2015. We also assessed correlates associated with attendance and non-attendance at a MH service. RESULTS: The study included 311 young people. MH services were attended in the 12 months before the survey by 38.3% with attempted suicide, 28.7% with a suicidal plan, 28.9% with suicidal ideation and 29.4% with self-harm. MH treatment administered by a GP was the most common MH service (25%); followed treatment by psychologist (15%) and psychiatrist (5%). Attendance at a MH service was observed highest alongside more severe self-reported depression. CONCLUSIONS: Potential underutilisation of MBS MH services by young people with self-harm and/or suicidal behaviours.

RESUMO

BACKGROUND: Clinicians increasingly serve youths from societal/cultural backgrounds different from their own. This raises questions about how to interpret what such youths report. Rescorla et al. (2019, European Child & Adolescent Psychiatry, 28, 1107) found that much more variance in 72,493 parents' ratings of their offspring's mental health problems was accounted for by individual differences than by societal or cultural differences. Although parents' reports are essential for clinical assessment of their offspring, they reflect parents' perceptions of the offspring. Consequently, clinical assessment also requires self-reports from the offspring themselves. To test effects of individual differences, society, and culture on youths' self-ratings of their problems and strengths, we analyzed Youth Self-Report (YSR) scores for 39,849 11-17 year olds in 38 societies. METHODS: Indigenous researchers obtained YSR self-ratings from population samples of youths in 38 societies representing 10 culture cluster identified in the Global Leadership and Organizational Behavioral Effectiveness study. Hierarchical linear modeling of scores on 17 problem scales and one strengths scale estimated the percent of variance accounted for by individual differences (including measurement error), society, and culture cluster. ANOVAs tested age and gender effects. RESULTS: Averaged across the 17 problem scales, individual differences accounted for 92.5% of variance, societal differences 6.0%, and cultural differences 1.5%. For strengths, individual differences accounted for 83.4% of variance, societal differences 10.1%, and cultural differences 6.5%. Age and gender had very small effects. CONCLUSIONS: Like parents' ratings, youths' self-ratings of problems were affected much more by individual differences than societal/cultural differences. Most variance in self-rated strengths also reflected individual differences, but societal/cultural effects were larger than for problems, suggesting greater influence of social desirability. The clinical significance of individual differences in youths' self-reports should thus not be minimized by societal/cultural differences, which-while important-can be taken into account with appropriate norms, as can gender and age differences.

RESUMO

Predicting success of a therapy in acute respiratory failure is clinically important. The FOx index (high-flow rate × FiO2 )/SpO2 was retrospectively applied to 70 patients who required high-flow nasal prongs for hypoxaemic and hypercapnic respiratory failure. The FOx index could predict between success and failure of high-flow nasal prongs at 6 hours, using non-invasive markers. This adds to the clinician's toolbox in managing respiratory failure and represents important proof of concept for a prospective study.

RESUMO

OBJECTIVES: This study aimed to (1) examine the strength of the association between mental disorders/mental health problems, risk behaviours and tobacco smoking among Australian adolescents, (2) compare rates of tobacco smoking among Australian adolescents with major depressive disorder, attention-deficit/hyperactivity disorder and/or conduct disorder in 2013/14 vs 1998, and (3) identify the extent to which an association between tobacco smoking and mental health problems among adolescents can be attributed to non-mental health risk factors. METHODS: The study utilised data from the first (1998) and second (2013/14) child and adolescent components of the National Surveys of Mental Health and Wellbeing. Both surveys identified nationally representative samples of Australian young people aged 4-17 years, living in private dwellings. Information was collected from parents and 13- to 17-year-olds about mental disorders, mental health problems, risk behaviours and tobacco smoking. RESULTS: In the 2013/14 survey, the rate of current tobacco smoking among those with a mental disorder was 20% compared to 5% in those without a mental disorder. Rates were highest for young people with conduct disorder (50%), major depressive disorder (24%) and anxiety disorders (19%). In 2013/14, 38% of current tobacco smokers had a mental disorder and 32% reported self-harm and/or suicidal ideation vs 10% and 5%, respectively, among adolescents who had never smoked. Females with mental disorders or reporting self-harm or suicidal ideation had higher rates of current smoking than males. Other significant factors associated with current smoking included school-related problems, binge eating and having had more than one sexual partner. CONCLUSION: While smoking rates in 13- to 17-year-olds with mental disorders had declined since 1998, the strength of the association between mental disorders and smoking had increased, especially among females. Our findings highlight the need to address the tobacco smoking among adolescents with mental disorders, particularly females.

RESUMO

INTRODUCTION: Palliative care aims to improve the quality of life of patients with a life-limiting or life-threatening illness and is multifaceted involving comprehensive interdisciplinary assessments and interventions. Interdisciplinary palliative care in the setting of untreatable cancer diagnoses is of particular importance due to additional considerations that must be taken as patients are often undergoing palliative chemotherapy and/or radiation therapy. These patients' complexity warrants special considerations and attentiveness to drug-related problems. CASE REPORT: The purpose of this case report is to highlight the importance of both complete and comprehensive medication histories in cancer care and the impact of proton pump inhibitors on pancreatic enzyme insufficiencies secondary to pancreatic cancers. This case involves a drug-related problem involving three medications that are commonly used in pancreatic cancer patients: pancreatic enzyme replacement therapy, a proton pump inhibitor, and a fluoroquinolone antibiotic. The patient presented in this case report is an 80-year-old man diagnosed with unresectable pancreatic cancer with a history of symptomatic gastroesophageal reflux disease managed with a proton pump inhibitor, specifically tablets of the 40 mg strength of pantoprazole magnesium taken orally once daily. During the patient's first of five 28-day cycles of palliative-intent chemotherapy with gemcitabine and nab-paclitaxel, the patient presented to the emergency department due to fever and, although not severely neutropenic, was prescribed amoxicillin/clavulanate and ciprofloxacin due to his advanced age. After reading a patient advisory on a ciprofloxacin patient information sheet that advised avoidance of concomitant administration of ciprofloxacin and magnesium, the patient self-discontinued his pantoprazole as it was a magnesium salt formulation. This discontinuation was followed by two weeks of persistent foul-smelling diarrhea, flatulence, and abdominal pain. MANAGEMENT AND OUTCOME: The patient's healthcare team symptomatically managed the patient with oral and intravenous rehydration unaware of the cause of the symptoms. A trial of pancreatic enzyme replacement therapy was initiated; however, it was unsuccessful in resolving his symptoms. After further investigation and a more in-depth patient interview, it was discovered that the discontinued proton pump inhibitor was likely the cause of the patient's new symptoms and was subsequently re-initiated. Pancreatic enzyme replacement therapy in combination with re-initiation of pantoprazole therapy essentially resolved all symptoms. DISCUSSION: Before his diagnosis of unresectable pancreatic cancer, the patient had been on proton pump inhibitor therapy for nearly a decade. He had significant atrophy of the pancreas and an undoubtedly decreased pancreatic enzyme and bicarbonate production; however, he did not experience foul-smelling diarrhea indicative of pancreatic enzyme insufficiency while he was on his proton pump inhibitor. We believe that with his proton pump inhibitor therapy, he was unknowingly being partially treated for his worsening pancreatic enzyme insufficiency, specifically the component related to his lack of bicarbonate production and secretion. His discontinuation of his proton pump inhibitor led to a decrease in gastric acid, small bowel, and normal intraduodenal pH, which resulted in any remaining pancreatic enzyme reserve to become non-functional, unmasking his pancreatic enzyme insufficiency. An initial empiric trial of pancreatic enzyme replacement therapy failed in the absence of a proton pump inhibitor; however, within days of restarting his proton pump inhibitor along with pancreatic enzyme replacement therapy, his gastrointestinal symptoms completely resolved. This is due to the decrease of gastric and intraduodenal acidity, which better enabled the function of pancreatic enzymes present in pancreatic enzyme replacement therapy.

RESUMO

INTRODUCTION: The metastatic pancreatic adenocarcinoma clinical trial (MPACT) trial established gemcitabine (gem) and nab-paclitaxel (nab) as a standard treatment for pancreatic cancer utilizing granulocyte colony-stimulating factors to manage neutropenia. This was a challenge for jurisdictions that do not use granulocyte colony-stimulating factors in palliative settings. We developed dosage guidelines to dose modify gem and nab without granulocyte colony-stimulating factors. We undertook a retrospective review to determine the efficacy and safety of these dose adjustment guidelines in the real world. METHODS: A multi-centered, retrospective chart review was performed on pancreatic patients between December 1, 2014, and August 21, 2018. Provincial electronic medical health records were reviewed. Using Log-rank statistics we determined the patient's progression-free survival and overall survival. RESULTS: Of 248 patients, 209 met patient selection criteria. Patients were excluded if they were lost to follow-up, on gem alone prior to nab/gem combination therapy or did not receive nab or gem. Patients who received nab/gem as first-line therapy had a median progression-free survival of 6.3 months (95% CI, 5.1-7.4), and median overall survival of 11.1 months (95% CI, 9.5-12.8). Those who received gem/nab in the second line had a median progression-free survival of 4.6 months (95% CI, 2.8-6.5), and median overall survival of 19.3 months (95% CI, 12.6-26.0). CONCLUSIONS: The patient's progression-free survival and overall survival taking nab/gem using our dose modification algorithm were equivalent or superior to the MPACT trial's progression-free survival and overall survival. Gem/nab can be given by our dose modification scheme without granulocyte colony-stimulating factor.

RESUMO

OBJECTIVE: Patient-reported outcomes of health-related quality-of-life (HRQoL) are important descriptors of population health. A recent Australian adolescent population survey provided a unique opportunity to derive preference-based HRQoL. METHODS: Data from 2967 adolescents aged 11-17 years were analysed. An interviewer-led parent/carer questionnaire was administered for demographic variables and mental disorders of adolescents during previous 12 months using the Diagnostic Interview Schedule for Children. A self-report survey was administered to derive HRQoL using the child health utility nine-dimensions instrument (CHU-9D). Weighted HRQoL was derived for several demographic groups, mental disorder diagnosis, and youth risk behaviours. RESULTS: The total population had a mean utility of 0.78 [standard deviation (SD): 0.20]. Males had a significantly higher mean utility (0.81, SD 0.18) than females (0.76, SD: 0.21) (Cohen's d = 0.23, p < 0.001), and utility decreased with age for both males and females (p < 0.001). Family type and some parent/carer variables were associated with significant lower HRQoL scores with small effect size. Youth risk behaviours were associated with reduced HRQoL with moderate effect sizes. Adolescents who self-harmed, had suicidal ideation, or had a mental disorder had significantly lower utilities scores with moderate to large effect sizes compared to those who did not have such conditions. CONCLUSIONS: This study has provided contemporary Australian population norms for HRQoL in adolescents that may be used as cross comparison between studies as well as indicators allowing estimation of population health (e.g. estimation of the burden of disease) and can be used to populate future economic models.

RESUMO

OBJECTIVES: Despite substantial investment by governments, the prevalence of mental health disorders in developed countries remains unchanged over the past 20 years. As 50% of mental health conditions present before 14 years of age, access to high-quality mental health care for children is crucial. Barriers to access identified by parents include high costs and long wait times, difficulty navigating the health system, and a lack of recognition of the existence and/or severity of the child's mental health disorder. Often neglected, but equally important, are clinician views about the barriers to and enablers of access to high-quality mental health care. We aimed to determine perspectives of Australian clinicians including child and adolescent psychiatrists, paediatricians, psychologists and general practitioners, on barriers and enablers within the current system and components of an optimal system. METHODS: A total of 143 clinicians (approximately 35 each of child and adolescent psychiatrists, paediatricians, child psychologists and general practitioners) from Victoria and South Australia participated in semi-structured phone interviews between March 2018 and February 2019. Inductive content analysis was applied to address the broad study aims. FINDINGS: Clinician-identified barriers included multi-dimensional family factors, service fragmentation, long wait times and inadequate training for paediatricians and general practitioners. Rural and regional locations provided additional challenges but a greater sense of collaboration resulting from the proximity of clinicians in rural areas, creating an opportunity to develop support networks. Suggestions for an optimal system included novel ways to improve access to child psychiatry expertise, training for paediatricians and general practitioners, and co-located multidisciplinary services. CONCLUSION: Within the current mental health system for children, structural, training and workforce barriers prevent optimal access to care. Clinicians identified many practical and systemic ideas to improve the system. Implementation and evaluation of effectiveness and cost effectiveness of these ideas is the next challenge for Australia's children's mental health.

RESUMO

Colorectal cancer is one of the most common malignancies diagnosed in Canada. Currently, adjuvant colorectal cancer treatment primarily includes chemotherapeutic regimens such as FOLFOX6 (5-fluorouracil, leucovorin, oxaliplatin) or CAPOX (capecitabine, oxaliplatin), as well as alternative regimens such as TOMOX (raltitrexed, oxaliplatin). However, the prevalence of drug shortages in today's society may make these preferred regimens inaccessible. The purpose of this case report is to highlight the tolerability of an alternative adjuvant regimen (pemetrexed plus oxaliplatin) that has undergone both phase I and II clinical trials for the treatment of colorectal cancer. The patient presented in this case report is a 57-year-old female diagnosed with Stage III colon cancer. This patient received seven cycles of pemetrexed plus oxaliplatin and experienced several adverse events, with the majority of them being mild in nature including fatigue and cold dysesthesia. However, the patient also experienced progressive neuropathy which required a dose reduction and subsequent discontinuation of oxaliplatin. Overall, pemetrexed and oxaliplatin's tolerability seems comparable to other regimens used to treat colorectal cancer and could potentially be an option to consider in the future for alternative treatment of colorectal cancer pending further trials.

RESUMO

AIM: To determine: (i) wait times and out-of-pocket costs for children attending private specialists for initial mental health appointments; and (ii) whether these differed between specialists working in metropolitan versus rural areas and in low, medium and high socio-economic areas. METHODS: Prospective secret shopper study whereby a researcher posed as a parent seeking an appointment for her child with anxiety or attention-deficit/hyperactivity disorder. We contacted 317 private paediatrician, psychiatrist and psychologist practices in Victoria and South Australia between 12 March and 5 May 2019. RESULTS: One third (29.8%) of private practices were closed to new referrals. The average wait times for paediatricians, psychiatrists, and psychologists were 44, 41 and 34 days, respectively. Average out-of-pocket costs quoted were AU$120 for paediatricians, AU$176 for psychiatrists and AU$85 for psychologists. CONCLUSION: Parents face extensive wait times and substantial out-of-pocket costs when seeking private mental health services for their child.

RESUMO

The positive cognitive triad (positive cognitions about the self, world, and future) has been considered a protective factor against depressive symptoms. This study examines three conceptualizations of the positive cognitive triad and their relation to depressive symptoms. Analyses were replicated in two samples in order to provide evidence for the validity of findings. Two samples (n1 = 2982, Mage = 13.04, Rangeage = 11-15 years; n2 = 2540, Mage = 13.11, Rangeage = 11-16 years) of Australian adolescents completed the Positive Cognitive Triad Inventory and Center for Epidemiological Studies Depression Scale. Findings supported the notion that the overall positive cognitive triad is a protective factor for depressive symptoms, and specifically, the role of positive cognitions about the self in this protection. After future studies examine the directionality of the relation between positive cognitions and depressive symptoms, mental health providers using cognitive behavioral approaches may consider examining positive cognitions with patients.

RESUMO

BACKGROUND: Over the past 20 years the prevalence of child and adolescent mental disorders in high-income countries has not changed despite increased investment in mental health services. Insufficient contact with mental health services may be a contributing factor; however, it is not known what proportion of children have sufficient contact with health professionals to allow delivery of treatment meeting minimal clinical practice guidelines, or how long children experience symptoms prior to receiving treatment. AIMS: To investigate the level of mental healthcare received by Australian children from age 4 years to 14 years. METHOD: Trajectories of mental health symptoms were mapped using the Strengths and Difficulties Questionnaire. Health professional attendances and psychotropic medications dispensed were identified from linked national Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme records. RESULTS: Four trajectories of mental health symptoms were identified (low, high-decreasing, moderate-increasing and high-increasing). Most children with mental health symptoms had few MBS mental health attendances, and only a minority received care meeting study criteria for minimally adequate treatment. Children in the high-increasing and moderate-increasing trajectories were more likely to access care, yet there was no evidence of improvement in symptoms. CONCLUSIONS: It is important that children and adolescents with mental health problems receive treatment that meets minimal practice guidelines. Further research is needed to identify the quality of care currently provided to children with mental health difficulties and how clinicians can be best funded and supported to provide care meeting minimal practice guidelines. DECLARATION OF INTERESTS: None.

RESUMO

Background: Understanding resting energy expenditure (REE) is important for determining energy requirements; REE might be altered in individuals with cancer. The objective of this study was to characterize determinants of REE in patients with stages II-IV colorectal cancer (CRC).Methods: REE was measured via indirect calorimetry in patients with newly diagnosed CRC. Computerized tomography images from medical records ascertained skeletal muscle and total adipose tissue cross-sectional areas, which were then transformed to lean soft tissue (LST) and fat mass (FM) values (in kg). Linear regression assessed determinants of REE.Results: 86 patients were included (n = 55, 64.0% male; 60 ± 12 years old; median body mass index: 27.6, interquartile range: 24.3-31.2 kg/m2), with most (n = 40) having stage III disease. Age, sex, and weight were significant predictors of REE [R2 = 0.829, standard error of the estimate (SEE): 128 kcal/day, P < 0.001]. Replacing weight with LST and FM yielded a similar model, with age, sex, LST, and FM predictive of REE (R2 = 0.820, SEE: 129 kcal/day, p < 0.001).Conclusion: Age, sex, weight, LST, and FM were the main contributors to REE. Further investigation of REE changes over time and its relationship to total energy expenditure, dietary intake, and clinical outcomes should be explored.

RESUMO

OBJECTIVE: To assess changes in barriers to mental health care for children and adolescents over 16 years. METHODS: We used data from two nationally representative surveys of Australian children and adolescents (4-17 years old), conducted in 1998 (N = 4509) and 2013-2014 (N = 6310). Barriers to care were assessed among parents who had reported a perceived partially met or unmet need for their child in the past 6 months in 1998, and the past 12 months in 2013-2014; barriers were similarly assessed among adolescents in relation to themselves. We addressed measurement inconsistencies between surveys by harmonising barriers to accommodate differences in wording and performing sensitivity analyses among those with a 1-month disorder to equalise the timeframes in which barriers were assessed. To assess change, we examined whether the rank order of the three most commonly endorsed barriers changed and whether the 95% confidence intervals (CI) around their estimates overlapped. RESULTS: Similar proportions of parents reported a partially met or unmet need in 1998 (12.9%, 95% CI = [11.7, 14.0]) as in 2013-2014 (14.3%, 95% CI = [13.2, 15.3]), but the ratio of unmet to partially met need decreased from 3:1 in 1998 to 1:1 in 2013-2014. Top three parent-endorsed barriers ('self-reliance', 'unsure where to get help', and 'cost') were the same at both time points; 'self-reliance' decreased from 65.9% (95% CI = [61.1%, 70.7%]) to 34.9% (95% CI = [31.5%, 38.3%]). Top two adolescent-endorsed barriers ('self-reliance' and 'concerned what others might think') were the same at both time points, the third differed, but none of them decreased. CONCLUSION: Perceived unmet need for mental health care for children and adolescents may have decreased between 1998 and 2013-2014, but the gap in receiving sufficient care may have increased. Despite investments in community awareness and treatment during this period, key barriers seemed largely unchanged. For parents, the decrease in self-reliance may reflect a positive shift in beliefs about the potential benefits of treatment.

RESUMO

OBJECTIVE: Poorer mental health in adulthood is associated with increased risk of cardiovascular disease and reduced life expectancy. However, little is known of the molecular pathways underpinning this relationship and how early in life adverse metabolite profiles relate to self-reported variation in mental health. We examined cross-sectional associations between mental health and serum metabolites indicative of cardiovascular health, in large Australian population-based cohorts at two stages of the life-course. METHODS: We characterised cross-sectional serum nuclear magnetic resonance metabolite profiles of positively and negatively framed mental health in a large population-based sample of Australian 11- to 12-year-olds (n = 1172; 51% girls) and mid-life adults (n = 1322; mean age 45 years; 87% women). We examined multiple standard self-report mental health scales, spanning psychosocial health, general well-being, life satisfaction, and health-related quality of life. Linear regression was used to investigate the cross-sectional association between mental health and each metabolite (n = 73) in children and adults separately, unadjusted and adjusted for age, sex, socioeconomic position and body mass index. RESULTS: Better child and adult mental health were associated with lower levels of the inflammatory marker glycoprotein acetyls, and a favourable, less atherogenic lipid/lipoprotein profile. Patterns of association in children were generally weaker than in adults. Associations were generally modest and partially attenuated when adjusted for body mass index. CONCLUSIONS: In general, metabolite profiles associated with better child and adult mental health closely aligned with those predictive of better cardiovascular health in adults. Our findings support previous evidence for the likely bidirectional relationship between mental health and cardiovascular disease risk, by extending this evidence base to the molecular level and in children.

RESUMO

Visceral adipose tissue (VAT) is a metabolically active organ, associated with higher risk of malignancies. We evaluated whether VAT is associated with the risk of hepatocellular carcinoma (HCC) in patients presenting with cirrhosis as well as HCC recurrence after liver transplantation (LT). Patients with cirrhosis (n = 678; 457 male) who were assessed for LT (289 with HCC) were evaluated for body composition analysis. Patients who underwent LT (n = 247, 168 male) were subsequently evaluated for body composition, and 96 of these patients (78 male) had HCC. VAT, subcutaneous adipose tissues, and total adipose tissues were quantified by computed tomography at the level of the third lumbar vertebra and reported as indexes (cross-sectional area normalized for height [square centimeters per square meter]). At the time of LT assessment, the VAT index (VATI) was higher in male patients with HCC compared to non-HCC patients (75 ± 3 versus 60 ± 3 cm2 /m2 , P = 0.001). The VATI, subcutaneous adipose tissue index, and total adipose tissue index were higher in male patients with HCC compared to non-HCC patients. By multivariate analysis, male patients with VATI ≥65 cm2 /m2 had a higher risk of HCC (hazard ratio, 1.90; 95% confidence interval, 1.31-2.76; P = 0.001). In male patients with HCC who underwent LT, a VATI ≥65 cm2 /m2 adjusted for Milan criteria was independently associated with higher risk of HCC recurrence (hazard ratio, 5.34; 95% confidence interval, 1.19-23.97; P = 0.03). CONCLUSION: High VATI is an independent risk factor for HCC in male patients with cirrhosis and for recurrence of HCC after LT. (Hepatology 2018;67:914-923).
