Abstract
BACKGROUND The current study aimed to compare current suicide rates, trends, previous treatment, suicidality and mental health diagnoses for First Nations and non-Indigenous young people who died by suicide. METHODS Age-specific suicide rates (ASSRs) were calculated per 100,000 persons/year using suicides aged 10-19 years in the Queensland Suicide Register. Rate Ratios (RRs) and 95 % CIs compared ASSRs for First Nations and non-Indigenous youth dying by suicide in Queensland, Australia, from 2001 to 2018. Risk ratios (RiskR) with 95 % CIs compared characteristics between First Nations and non-Indigenous youth suicides. Joinpoint regression was used to identify any changes in trends and annual percentage change (APC) in suicides with 95 % CIs. RESULTS The First Nations youth ASSR was 24.71 deaths per 100,000 persons/year, 4.5 times the non-Indigenous ASSR (95 % CI = 3.74-5.38, p < 0.001). Both non-Indigenous and First Nations suicide trends were stable with no joinpoints (APC: 0.3 %, 95 % CI: -1.6-2.2, p = 0.78; APC: 0.9 %, 95 % CI: -0.2-2.1, p = 0.11). Less than a quarter (23.9 %) of First Nations young people had ever received mental health treatment, significantly fewer than non-Indigenous youth (RiskR = 0.80, 95 % CI = 0.71-0.90, p < 0.001). Similarly, in the three months preceding their death, only 14.5 % of First Nations young people had received mental health treatment (RiskR = 0.89, 95 % CI = 0.83-97, p = 0.015). LIMITATIONS Reported mental illness, suicidality and help-seeking could be underreported due to concealment from family or police. CONCLUSIONS The current study finds no change in the gap between the First Nations and Non-Indigenous youth suicide rates nor evidence of decrease in the First Nations youth suicide rate. There is a need for alternative approaches to Indigenous youth suicide prevention, such as assertive outreach models outside of traditional triage and mental health systems to proactively build trusting relationships with young people in communities to identify young people needing support.

Abstract
CASE HISTORY Two clusters of mortality among endangered tūturuatu/tchūriwat'/shore plover (Thinornis novaeseelandiae) have occurred at captive breeding facilities around New Zealand in recent years. In the first, four chicks died at Pūkaha National Wildlife Centre (Mount Bruce, NZ) in February 2016, and in the second five adult birds at the Cape Sanctuary (Cape Kidnappers, NZ) died in 2022. CLINICAL FINDINGS In 2016, four chicks were noted to become weak, have increased vocalisations and closed eyes prior to death. The remaining chicks were treated for 5 days with amoxycillin/clavulanate orally twice daily. Water containers and brooders were cleaned and disinfected with chlorhexidine. No further mortality was seen.In the 2022 cluster, three adult breeding birds died acutely and five others showed inappetence, weight loss and diarrhoea approximately 10 days after heavy rains flooded the local river. The five birds were treated with amoxycillin/clavulanate orally twice daily and oral fluids for 5 days. Two birds died and three survived. No breeding occurred in the aviaries in the following season. PATHOLOGICAL FINDINGS In 2016, the chicks showed pulmonary changes ranging from congestion and oedema to heterophilic inflammation consistent with septicaemia.In 2022, the adult birds showed proliferation of bacteria in the distal small intestine associated with mucosal ulceration and heterophilic infiltration. Acid-fast staining of the caecal contents in one bird showed organisms consistent with Cryptosporidium spp. LABORATORY FINDINGS Aerobic bacterial cultures of the lung and liver of two affected chicks carried out in 2016 showed heavy growth of Plesiomonas shigelloides. The same organism was cultured from water trays and holding tanks containing water boatmen (Sigara arguta) on which the chicks were fed.In 2022, cultures from the livers of three dead birds each showed a mixed bacterial growth with differing dominant organisms (Aeromonas sobria, Hafnia alvei, Citrobacter freundii and an Enterococcus sp.). PCR and sequencing confirmed Cryptosporidium parvum in the caecum of one bird. Fresh faeces from 24 breeding birds from the captive breeding facilities were negative by PCR for Cryptosporidium spp.The captive breeding facilities obtain water for the aviaries and aquatic invertebrates to feed to the chicks from local freshwater sources. Water quality testing at the Cape Sanctuary revealed concentrations of faecal indicator bacteria in excess of safe drinking water guidelines, with peaks following heavy rainfall. CLINICAL RELEVANCE Fluctuations in water quality associated with mammalian faecal bacteria can adversely affect bird health and impact on captive rearing of endangered wildlife.

Abstract
Coastal vegetated ecosystems are acknowledged for their capacity to sequester organic carbon (OC), known as blue C. Yet, blue C global accounting is incomplete, with major gaps in southern hemisphere data. It also shows a large variability suggesting that the interaction between environmental and biological drivers is important at the local scale. In southwest Atlantic salt marshes, to account for the space occupied by crab burrows, it is key to avoid overestimates. Here we found that southern southwest Atlantic salt marshes store on average 42.43 (SE = 27.56) Mg OC·ha-1 (40.74 (SE = 2.7) in belowground) and bury in average 47.62 g OC·m-2·yr-1 (ranging from 7.38 to 204.21). Accretion rates, granulometry, plant species and burrowing crabs were identified as the main factors in determining belowground OC stocks. These data lead to an updated global estimation for stocks in salt marshes of 185.89 Mg OC·ha-1 (n = 743; SE = 4.92) and a C burial rate of 199.61 g OC·m-2·yr-1 (n = 193; SE = 16.04), which are lower than previous estimates.

Abstract
AIM To report prospective longitudinal data of early vocaliszations of infants identified "at-risk" of cerebral palsy (CP) for early identification of communication impairment. METHOD This case-control longitudinal prospective cohort study reports on the assessment of 36 infants, 18 identified as at-risk of CP at the time of enrolment and 18 typically developing (TD) children, at three time points: 6 months, 9 months and 12 months of age, Data were obtained through criterion and norm referenced assessments of vocaliszation behaviors. RESULTS Early vocal behaviors of infants identified as at-risk of CP did not differ from their age matched peers at 6 months of age, however, significant group differences emerged at 9 and 12 months when pre-canonical and canonical babble typically emerge. Generalized linear mixed models analysis showed that the rate of development of early language ability and more complex speech-related vocal behaviors was slower for infants at risk of CP when compared to TD infants, with over 75% of infants with CP showing below normal vocal production and impaired language by 12 months of age. INTERPRETATION Our data suggest characteristics of infant vocalizations associated with pre-canonical and canonical babbling provide a strong evidence base for predicting communication outcomes in infants at risk of CP.

Abstract
INTRODUCTION Appendicitis remains the most common intra-abdominal surgical emergency, yet many patients receive postoperative antibiotics and intra-abdominal drains against recommended guidelines. This study assesses the impact of an educational poster on the appropriate use of postoperative antibiotics and intra-abdominal drains in appendicectomy patients. METHODS Patients who underwent an appendicectomy between January and April 2019 ('Poster absent' group) as well as between November 2019 and February 2020 ('Poster present' group) were identified. Data were collected on patient demographics, the presence of complicating features (ie appendiceal abscesses, intraperitoneal pus, gangrene and/or perforation) as well as the use of postoperative antibiotics and intra-abdominal drains in accordance with World Society of Emergency Surgery guidelines. RESULTS One hundred and thirty patients were included in the 'Poster absent' (73 patients) and 'Poster present' (57 patients) groups. After introducing the educational poster there was a significant reduction in the use of postoperative antibiotics (60.5% to 13.8%; p<0.0001) and an insignificant reduction in intra-abdominal drain use (15.2% to 13.2% p>0.05) that were contraindicated in simple appendicitis. There was a significant improvement in the use of postoperative antibiotics (71.9% to 100%; p=0.0019) and an insignificant increase in intra-abdominal drain use (58.8% to 64.3%; p>0.05) that were indicated in complicated appendicitis. The rates of wound infection (4.10% to 0%; p=0.2556) and ileus/obstruction (5.48% to 1.75%; p=0.3846) also reduced. CONCLUSION This small study demonstrated that a simple and appropriately targeted intervention of an educational poster can significantly improve and reduce variation in the management of appendicectomy patients and may reduce postoperative complications.

Abstract
Microplastic (MPL) contamination in the marine environment is extensively studied yet little is known about the extent of MPL abundance in seagrass beds. The aim of this study was to evaluate MPL accumulation in coastal seagrass (Zostera marina) beds in the Baltic Sea, Estonia. Surface water was sampled by pumping using 40 μm plankton net, and sediments by trowel. MPL was extracted with NaCl, identified by microscopy and ATR-FTIR on selected samples. Surface water in the seagrass beds had 0.04-1.2 (median 0.14) MPL/L, similar to other areas of the Baltic Sea. Sediments had 0-1817 (median 208) MPL/kg (dwt), much higher than previously recorded from adjacent unvegetated and offshore sediments, thereby suggesting a strong ability of the sediments in seagrass beds to retain MPL. Of identified MPL, blue fibres were dominant in both the sampled media. Sediment characterization showed a correlation between MPL counts with poorly sorted sediments.

Abstract
Abstract
A liquid chromatographic (LC) method for the determination of diquat and paraquat herbicides/desiccants in potatoes was collaboratively studied in 6 laboratories. Analytes are extracted from 5 g sample with dilute acid by using a microreflux procedure; the hydrolysate is adjusted to pH 9–10 and passed through a disposable silica cartridge for rapid cleanup and preconcentration. Analytes are separated on a reversed-phase LC column and are measured as their heptanesulfonate ion pairs by UV detection. Each collaborator determined diquat and paraquat at 4 levels (0.05,0.1,0.5, and 1.0 ppm) in blind duplicate samples plus 2 blind negative control samples. Potatoes, obtained from each participant’s region, were spiked by the collaborators with unknown aqueous solutions containing no analyte or a mixture of diquat and paraquat standards. Repeatability and reproducibility relative standard deviations (RSDr and RSDR) averaged 17.1 and 29.0%, respectively, for determination of diquat and 10.8 and 29.5%, respectively, for paraquat. For analysis of standard solutions, RSDr and RSDR values were 6.3 and 12.0%, respectively, for diquat and 7.3 and 13.9%, respectively, for paraquat. Accuracy, measured by comparison with true spiking values (absolute recovery) averaged 77.6 and 76.2% for diquat and paraquat, respectively, and ranged from 71.8 to 88.0% for both compounds. The method was adopted first action by AOAC International.

Abstract
The use of non-aqueous cellulose-based formulations for extrusion-spheronisation (E-S) is investigated. A 10 wt% hydroxypropyl cellulose/isopropyl alcohol solution (HPC/IPA) was identified as a suitable sticky liquid binder for preparing non-aqueous pastes. Preliminary tests were performed on a series of pastes using a ram as well as a laboratory roller screen extruder, since the former is commonly used in batch testing and the latter replicates the shear range in a manufacturing screen extruder. Pellets with acceptable size and shape distributions were obtained with Avicel® HFE-102 NF/HPC/IPA for ram E-S, and with Avicel® RC-591/HPC/IPA for screen E-S. Further investigation was performed with calcium carbonate added as a model active pharmaceutical ingredient. Both formulations were able to generate pellets with acceptable size and shape characteristics at up to 50 wt% carbonate loading: further work is required to optimise yields.

Abstract
Diabetes increases the risk and worsens the progression of cognitive impairment. The hippocampus is an important domain for learning and memory. We previously showed that endothelin-1 (ET-1) reduced diabetes-induced inflammation in hippocampal neurons, suggesting a neuroprotective effect. Given that neurons and endothelial cells within the neurovascular unit depend on each other for proper function, we investigated the effect of ET-1 on brain-derived neurotrophic factor (BDNF) synthesis, a key neurotrophin and prosurvival factor, in neuronal (HT22 hippocampal neurons) and brain microvascular endothelial (BMEC-5i) cells under normal and diabetes-mimicking (high glucose plus palmitate) conditions. Cells were treated with exogenous ET-1 or ET receptor antagonists including ET(B) receptor selective antagonist BQ788 (1 microM) or dual-receptor antagonist bosentan (10 microM). Mature (m)BDNF, proBDNF and caspase-3 levels were measured by Western blotting. Diabetic conditions reduced the prosurvival mBDNF/proBDNF ratio in both HT22 and BMEC-5i cells. Addition of exogenous ET-1 had no effect on the BDNF system in HT22 cells in diabetic conditions. Both HT22 and BMEC-5i cells had an increase in the mBDNF/proBDNF ratio when grown in diabetes-simulating conditions in the presence of endothelin receptor inhibition. These data suggest that blockade of ET-1 may provide neuroprotection to hippocampal cells through the modulation of the BDNF system.

Abstract
The global epidemic of diabetes is of significant concern. Diabetes associated vascular disease signifies the principal cause of morbidity and mortality in diabetic patients. It is also the most rapidly increasing risk factor for cognitive impairment, a silent disease that causes loss of creativity, productivity, and quality of life. Small vessel disease in the cerebral vasculature plays a major role in the pathogenesis of cognitive impairment in diabetes. Endothelin system, including endothelin-1 (ET-1) and the receptors (ET(A) and ET(B)), is a likely candidate that may be involved in many aspects of the diabetes cerebrovascular disease. In this review, we took a brain-centric approach and discussed the role of the ET system in cerebrovascular and cognitive dysfunction in diabetes.

The main objective of this survey was to examine variability in milk urea nitrogen (MUN) for Dairy Herd Improvement Association (DHIA) herds in the northeastern United States (the Northeast), examine trends in dairy cow diet composition, and determine potential relationships for MUN and diet composition. Trends in milk fat and protein concentrations, milk yield, days in milk on test day, and lactation number of the cows were also evaluated. The data set for the survey included 10,839,461 DHIA dairy cow records from 2004 to 2015 for 13 states (CT, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VA, VT, and WV) and was retrieved from Dairy Records Management Systems (Raleigh, NC). Average (across states and years) milk yield, milk fat, and milk protein were 31.6 ± 0.24 kg/d, 3.85 ± 0.021%, and 3.13 ± 0.013%, respectively. No obvious trends were observed for milk fat or protein content, but milk yield steadily increased during the survey period. Milk urea N concentration averaged 13.3 ± 0.13 mg/dL, with no obvious or consistent trends. Examination of variability in dairy feed cost and all milk price for the Northeast indicated that high MUN generally coincided with high feed cost and high milk price. For the diet composition survey, 9,707 records of total mixed ration (TMR) analyses, unrelated to the milk composition data set, from the Cumberland Valley Analytical Service (Maugansville, MD) database were examined. Concentration of TMR crude protein (CP) decreased from 17.1% in 2007 to 16.4% in 2015, but there was not an obvious trend in soluble protein concentration. Concentration of TMR neutral detergent fiber (NDF) and 24-h in vitro NDF degradability declined steadily during the survey period and was accompanied by a steady increase in TMR starch concentration. Examination of these unrelated data sets revealed lack of correlation between MUN and diet chemical composition. Thus, we conclude that individual cow MUN in Northeast dairy herds fluctuated between 2004 and 2015. It appeared that MUN followed variability in feed cost; however, ration feed ingredient data were not available to better define the reasons for the variations in MUN.

Abstract
BACKGROUND/OBJECTIVES: Subjects with type-2 diabetes are typically obese with dysfunctional adipose tissue (AT). Glucagon-like peptide-1 (GLP-1) analogues are routinely used to improve glycaemia. Although, they also aid weight loss that improves AT function, their direct effect on AT function is unclear. To explore GLP-1 analogues' influence on human AT's cytokine and extracellular matrix (ECM) regulation, we therefore obtained and treated omental (OMAT) and subcutaneous (SCAT) AT samples with Exendin-4, an agonist of the GLP-1 receptor (GLP-1R). SUBJECTS/METHODS: OMAT and abdominal SCAT samples obtained from women during elective surgery at the Royal Devon & Exeter Hospital (UK) were treated with increasing doses of Exendin-4. Changes in RNA expression of adipokines, inflammatory cytokines, ECM components and their regulators were assessed and protein secretion analysed by ELISA. GLP-1R protein accumulation was compared in paired AT depot samples. RESULTS: Exendin-4 induced an increase in OMAT adiponectin (P=0.02) and decrease in elastin expression (P=0.03) in parallel with reduced elastin secretion (P=0.04). In contrast to OMAT, we did not observe an effect on SCAT. There was no change in the expression of inflammatory markers (CD14, TNFA, MCP-1), collagens, TGFB1 or CTGF. GLP-1R accumulation was higher in SCAT. CONCLUSIONS: Independently of weight loss, which may bias findings of in vivo studies, GLP-1 analogues modify human OMAT physiology favourably by increasing the insulin-sensitising cytokine adiponectin. However, the reduction of elastin and no apparent effect on AT's inflammatory cytokines suggest that GLP-1 analogues may be less beneficial to AT function, especially if there is no associated weight loss.

Abstract
More and more healthcare professionals are becoming experienced in the use of the Internet and having seen some of the resources available they are now becoming able to identify the sorts of features which would be useful to them. This paper describes a study to identify what United Kingdom (UK) nurses, midwives and health visitors want from an Internet service dedicated to their needs. An online questionnaire was used to find out their views as to the importance of various possible content areas and to enable them to make comments. Data were obtained from 126 self-selecting respondents over two months, and the study is ongoing. Initial results revealed wide variations in the areas that were seen as being important and in the sorts of services they would find useful from the Internet; there were, however, some consistent themes. Respondents felt that speciality information, peer-reviewed articles and bibliographic databases were the most important areas and that job advertisements, local information and mailing lists were the least important. The importance of these results for future investment in and development of an Internet service for this group of users is considered.

Abstract
PURPOSE While laparoscopic cholecystectomy can be a routine procedure when biliary anatomy is normally located, cystic artery variations can easily disorientate the inexperienced surgeon to the anatomy of the hepatobiliary triangle. This study presents the clinically important anatomical variations of the cystic artery. METHODS PubMed, Medline, Cochrane Database of Systematic Reviews, and Google Scholar databases were searched to conduct a review of the existing English literature on the clinically important cystic artery variations. An aberrant vessel was defined as a vessel that originated from an atypical source and/or one that was present in a specimen in addition to the normal vessel. RESULTS The cystic artery originated typically from the right hepatic artery (79.02 %) and was found in the hepatobiliary triangle in only 5427 of 6661 (81.5 %) cases. Clinically important cystic artery variations are (1) the cystic artery located anterior to the common hepatic duct or common bile duct found in 485 of 2704 (17.9 %) and 228 of 4202 (5.4 %) of cases, respectively, (2) the cystic artery located inferior to the cystic duct found in 38 of 770 (4.9 %) of cases, (3) short cystic arteries found in 98 of 1037 (9.5 %) cases and (4) multiple cystic arteries found in (8.9 %) of cases. CONCLUSION These variations are common in the general population and can lead to inadvertent ligation of biliary ducts or aberrant vessels. Therefore, it is important for the hepatobiliary surgeon to be aware of these vascular anomalies to avoid operative complications.

Abstract
PURPOSE Psychological responses to cancer are widely believed to affect survival. We investigated associations between hope, optimism, anxiety, depression, health utility and survival in patients starting first-line chemotherapy for metastatic colorectal cancer. METHODS Four hundred twenty-nine subjects with metastatic colorectal cancer in a randomised controlled trial of chemotherapy completed baseline questionnaires assessing the following: hopefulness, optimism, anxiety and depression and health utility. Hazard ratios (HRs) and P values were calculated with Cox models for overall survival (OS) and progression-free survival (PFS) in univariable and multivariable analyses. RESULTS Median follow-up was 31 months. Univariable analyses showed that OS was associated negatively with depression (HR 2.04, P < 0.001) and positively with health utility (HR 0.56, P < 0.001) and hopefulness (HR 0.75, P = 0.013). In multivariable analysis, OS was also associated negatively with depression (HR 1.72, P < 0.001) and positively with health utility (HR 0.73, P = 0.014), but not with optimism, anxiety or hopefulness. PFS was not associated with hope, optimism, anxiety or depression in any analyses. CONCLUSIONS Depression and health utility, but not optimism, hope or anxiety, were associated with survival after controlling for known prognostic factors in patients with advanced colorectal cancer. Further research is required to understand the nature of the relationship between depression and survival. If a causal mechanism is identified, this may lead to interventional possibilities.

Abstract
INTRODUCTION Obtaining blood cultures prior to the administration of antimicrobial therapy was a key recommendation of the 2012 UK Surviving Sepsis Campaign. Few studies have examined the effect blood cultures have on clinical management and there have been none on acute surgical admissions. This retrospective study sought to evaluate the effect of blood cultures on clinical management in acute surgical admissions. METHODS Data on acute surgical patients admitted between 1 January and 31 December 2012 were extracted from hospital records. Patients given intravenous antibiotics within 24 hours of admission were identified. Data collected included antibiotics administered, blood culture results, admission observations and white blood cell count. Case notes were reviewed for patients with positive cultures to establish whether the result led to a change in management. RESULTS Of 5,887 acute surgical admissions, 1,346 received intravenous antibiotics within 24 hours and 978 sets of blood cultures were taken in 690 patients. The recommended two sets of cultures were obtained in 246 patients (18%). Patients who had blood cultures taken had the same in-hospital mortality as those who had none taken (3.6% vs 3.5%, p=0.97). Blood cultures were positive in 80 cases (11.6%). The presence of systemic inflammatory response syndrome did not increase positivity rates (12.9% vs 10.3%, p=0.28). Overall, cultures altered management in two patients (0.3%). CONCLUSIONS Blood cultures rarely affect clinical management. In order to assess the additional value that blood cultures bring to sepsis management in acute surgical admissions, a prospective randomised trial focusing on outcome is needed.
