Abstract
Despite overwhelming international evidence of elevated rates of poor mental health in LGBTQ+ youth compared to their cis-heterosexual peers, we know relatively little about effective mental health services for this population group. This study aims to produce the first early intervention model of "what works" to support LGBTQ+ youth with emerging mental health problems. Utilizing a mixed method case study, we collected data across 12 UK mental health service case study sites that involved: (a) interviews with young people, parents, and mental health practitioners (n = 93); (b) documentary analysis; (c) nonparticipant observation. The data analysis strategy was theoretical using the "explanation-building" analytical technique. Our analysis suggests an intersectional youth rights approach with 13 principles that must be enacted to provide good mental health services as advocated by the United Nations Convention on the Rights of the Child and World Health Organization. This approach should address the multiple forms of marginalization and stigmatization that LGBTQ+ youth may experience, enable informed independent decision-making, and uphold the right to freedom of safe self-expression. A rights-based approach to mental health services for LGBTQ+ young people is not prominent. This needs to change if we are to tackle this mental health inequality and improve the mental well-being of LGBTQ+ youth worldwide.

Abstract
BACKGROUND Phelan-McDermid syndrome (PMS) is a rare genetic disorder caused by SHANK3 pathogenic variants or chromosomal rearrangements affecting the chromosome 22q13 region. Previous research found that kidney disorders, primarily congenital anomalies of the kidney and urinary tract, are common in people with PMS, yet research into candidate genes has been hampered by small study sizes and lack of attention to these problems. METHODS We used a cohort of 357 people from the Phelan-McDermid Syndrome Foundation International Registry to investigate the prevalence of kidney disorders in PMS using a cross-sectional design and to identify 22q13 genes contributing to these disorders. RESULTS Kidney disorders reported included vesicoureteral reflux (n = 37), hydronephrosis (n = 36), dysplastic kidneys (n = 19), increased kidney size (n = 19), polycystic kidneys (15 cases), and kidney stones (n = 4). Out of 315 subjects with a 22q13 deletion, 101 (32%) had at least one kidney disorder, while only one out of 42 (2%) individuals with a SHANK3 pathogenic variant had a kidney disorder (increased kidney size). We identified two genomic regions that were significantly associated with having a kidney disorder with the peak associations observed near positions approximately 5 Mb and 400 Kb from the telomere. CONCLUSIONS The candidate genes for kidney disorders include FBLN1, WNT7B, UPK3A, CELSR1, and PLXNB2. This study demonstrates the utility of patient registries for uncovering genetic contributions to rare diseases. Future work should focus on functional studies for these genes to assess their potential pathogenic contribution to the different subsets of kidney disorders.

Abstract
The volume of the reconstructed tongue is considered a critical factor for tongue function. Studies investigating the difference in volume loss between the anterolateral thigh free flap (ALTF) and radial forearm free flap (RFFF) used in reconstruction of the tongue after hemiglossectomy are lacking. The aim of this study was to determine whether there is a significant difference in shrinkage between these two flaps. This was a retrospective study of all patients treated for tongue cancer by hemiglossectomy who underwent either ALTF or RFFF reconstruction at the University of Florida College of Medicine between January 2018 and April 2022. Computed tomography scans were used to measure the volumetric changes in the ALTF and RFFF at two time points over a 6-month period. Of the 85 patients assessed, 10 fulfilled the inclusion criteria: five were reconstructed with an ALTF and five with a RFFF. All underwent adjuvant radiotherapy. The mean ALTF percentage shrinkage was 39.6% ± 3.9%, while for the RFFF it was 51.1% ± 6.2% (P = 0.008). Therefore, it is recommended that the difference in volume loss between the two flaps is taken into consideration. It is suggested that in hemiglossectomy cases, the ALTF is made 1.4 times larger than the defect, while the RFFF is made 1.5 times larger.

Abstract
Chromosome X is often excluded from bovine genetic studies due to complications caused by the sex specific nature of the chromosome. As chromosome X is the second largest cattle chromosome and makes up approximately 6% of the female genome, finding ways to include chromosome X in dairy genetic studies is important. Using female animals and treating chromosome X as an autosome, we performed X chromosome inclusive genome-wide association studies in the selective breeding environment of the New Zealand dairy industry, aiming to identify chromosome X variants associated with milk production traits. We report on the findings of these genome-wide association studies and their potential effect within the dairy industry. We identify missense mutations in the MOSPD1 and CCDC160 genes that are associated with decreased milk volume and protein production and increased fat production. Both of these mutations are exonic SNP that are more prevalent in the Jersey breed than in Holstein-Friesians. Of the 2 candidates proposed it is likely that only one is causal, though we have not been able to identify which is more likely.

Abstract
The dynamic covalent chemistry of imines is utilized to conduct a regioselective as well as enantioselective synthesis of an unsymmetric (C1) chiral macrocycle from the reaction of an unsymmetric (C1) chiral dialdehyde, (S)-4, that contains a salicylaldehyde unit and a benzaldehyde unit, with lysine, an unsymmetric (C1) chiral diamine. The enantioselectivity is further enhanced in the presence of Zn2+. Compound (S)-4 in combination with Zn2+ is found to be a highly chemoselective as well as enantioselective fluorescent probe for lysine. It can be used to detect specific enantiomers of this amino acid.

Abstract
Bacillus Calmette-Guérin (BCG) confers heterologous immune protection against viral infections and has been proposed as vaccine against SARS-CoV-2 (SCV2). Here, we tested intravenous BCG vaccination against COVID-19 using the golden Syrian hamster model. BCG vaccination conferred a modest reduction on lung SCV2 viral load, bronchopneumonia scores, and weight loss, accompanied by a reversal of SCV2-mediated T cell lymphopenia, and reduced lung granulocytes. BCG uniquely recruited immunoglobulin-producing plasma cells to the lung suggesting accelerated local antibody production. BCG vaccination also recruited elevated levels of Th1, Th17, Treg, CTLs, and Tmem cells, with a transcriptional shift away from exhaustion markers and toward antigen presentation and repair. Similarly, BCG enhanced recruitment of alveolar macrophages and reduced key interstitial macrophage subsets, that show reduced IFN-associated gene expression. Our observations indicate that BCG vaccination protects against SCV2 immunopathology by promoting early lung immunoglobulin production and immunotolerizing transcriptional patterns among key myeloid and lymphoid populations.

Abstract
BACKGROUND Free tissue transfers for reconstruction following tongue resection has become standard practice. PURPOSE This study sought to evaluate volume shrinkage of the anterolateral thigh free (ALTF) reconstructing tongue defects at 6 months postoperative. The aim was to estimate a shrinkage factor for ALTF reconstructing hemi and total glossectomy. STUDY DESIGN, SETTING, SAMPLE This was an IRB-approved retrospective cohort study conducted at the head and neck service at the University of Florida, College of Medicine, Jacksonville (FL). This study targeted patients with tongue cancer from January 2018 to April 2022. INCLUSION CRITERIA patients with tongue squamous cell carcinoma (SCC) who were surgically treated by either hemi or total glossectomy and reconstructed with ALTF. Patients had to have a postoperative computer tomography scans at 1 and 6 months post-surgery. Patients with constant body mass index during 6 months postreconstruction. Additionally, the patients were to have been treated with adjuvant radiotherapy. EXCLUSION CRITERIA patients with recurrent tongue cancer and those who weren't reconstructed or managed with other treatment modalities. PREDICTOR VARIABLE Type of tongue resection hemi versus total glossectomy for treatment of tongue SCC. MAIN OUTCOME VARIABLE Shrinkage percentage of ALTF reconstructing tongue defects at 6 months postoperatively. COVARIATES Age and gender. ANALYSES Paired t-test and student t-test with level of significance P ≤ .05 were used to statistically analyze ALTF volume changes at 1 and 6 months postoperatively and ALTF shrinkage percentage at 6 months postreconstruction, respectively. RESULTS We identified 85 patients who were treated for tongue SCC during the time period of study. Out of the 85 patients, 11 patients were reconstructed with an ALTF. Eight males and 3 females with a mean age of 62.3 years old. Six patients had total glossectomy and 5 had hemi glossectomy. Patients with hemi glossectomy had a significant difference in mean average flap shrinkage of 39.6%, while in those with total glossectomy had 17.7% (P = .004). CONCLUSION AND RELEVANCE According to our results, we recommend that the flap size should be larger than the defect to adjust for volume shrinkage (1.4 times and 1.2 times for cases of hemi and total glossectomy, respectively).

Abstract
Genetic predisposition and dietary factors can impact cardiovascular disease (CVD) risk. Two important markers in assessing CVD risk are apolipoprotein (apo) B and apolipoprotein A1 plasma levels. These markers are measured as a ratio, with a high apoB:apoA1 ratio associated with increased CVD risk. Dietary and lifestyle recommendations are the cornerstone of managing primary and secondary CVD risk-mitigation strategies. One way to assess the impact of various dietary and lifestyle interventions on CVD risk is to evaluate the changes in CVD risk markers, such as apoB, apoA1, and apoB:apoA1 ratio. Various human studies have demonstrated the impact of dietary, macronutrient, and micronutrient interventions on apoB and apoA1 status. This review aims to elucidate dietary, macronutrient, micronutrient, and nutrigenetic considerations for impacting apoB and apoA1 levels. A low-carbohydrate, high-saturated-fat diet, low fiber intake, low vitamin and mineral intake, and zinc and iron deficiency are associated with an elevated apoB:apoA1 ratio. The Mediterranean diet, vegan diet, fermented dairy products, lower sugar intake, higher protein intake, higher polyunsaturated fat intake, and an omega-3-rich diet are associated with a decreased apoB:apoA1 ratio. Micronutrients associated with a decreased apoB:apoA1 ratio include vitamin D sufficiency, increased serum vitamin C, and magnesium. Variants in the APOE, APOA1, and FADS2 genes may alter the apoB:apoA1 ratio in response to various dietary interventions. When accounting for factors that may favorably alter the apoB:apoA1 ratio, researchers should consider a healthy diet sufficient in polyunsaturated fats, vitamins, minerals, trace minerals, and lower excess sugars.

Abstract
People on buprenorphine maintenance treatment (BMT) commonly present cognitive deficits that have been associated with illicit drug use and dropout from buprenorphine treatment. This study has compared cognitive responses to the Stroop Task and the Continuous Performance Task (CPT) among individuals on BMT, with recent drug use, and healthy controls and explored the associations between cognitive responses and drug use, craving, and buprenorphine use among participants on BMT. The participants were 16 individuals on BMT and 23 healthy controls. All participants completed a 60 min laboratory session in which they completed the Stroop Task and the CPT, a saliva drug test, a brief clinical history that collected substance-use- and treatment-related information, and the Opioid Craving Scale. The results showed that the BMT participants presented more commission errors (MBMT participants = 2.49; Mhealthy controls = 1.38; p = 0.048) and longer reaction times (MBMT participants = 798.09; Mhealthy controls = 699.09; p = 0.047) in the Stroop Task than did the healthy controls. More days on buprenorphine were negatively associated with reaction time in the CPT (-0.52) and the number of commission errors (-0.53), simple reaction time (-0.54), and reaction time correct (-0.57) in the Stroop Task. Neither drug use nor craving was significantly associated with the results for the cognitive tasks. Relative to the control participants, the BMT individuals performed worse in terms of longer reaction times and more commission errors in the Stroop Task. Within the BMT participants, longer times on buprenorphine were associated with better cognitive results in terms of faster reaction times for both tasks and lower commission errors for the Stroop Task.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a leading cause of 30-day mortality after metabolic and bariatric surgery (MBS). Multiple predictive tools exist for VTE risk assessment and extended VTE chemoprophylaxis determination. OBJECTIVE To review existing risk-stratification tools and compare their predictive abilities. SETTING MBSAQIP database. METHODS Retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed (2015-2019) for primary minimally invasive MBS cases. VTE clinical factors and risk-assessment tools were evaluated: body mass index threshold of 50 kg/m2, Caprini risk-assessment model, and 3 bariatric-specific tools: the Cleveland Clinic VTE risk tool, the Michigan Bariatric Surgery Collaborative tool, and BariClot. MBS patients were deemed high risk based on criteria from each tool and further assessed for sensitivity, specificity, and positive predictive value. RESULTS Overall, 709,304 patients were identified with a .37% VTE rate. Bariatric-specific tools included multiple predictors: procedure, age, race, gender, operative time, length of stay, heart failure, and dyspnea at rest; operative time was the only variable common to all. The body mass index cutoff and Caprini risk-assessment model had higher sensitivity but lower specificity when compared with the Michigan Bariatric Surgery Collaborative and BariClot tools. While the sensitivity of the tools varied widely and was overall low, the Cleveland Clinic tool had the highest sensitivity. The bariatric-specific tools would have recommended extended prophylaxis for 1.1%-15.6% of patients. CONCLUSIONS Existing MBS VTE risk-assessment tools differ widely for inclusion variables, high-risk definition, and predictive performance. Further research and registry inclusion of all significant risk factors are needed to determine the optimal risk-stratified approach for predicting VTE events and determining the need for extended prophylaxis.

Abstract
It is discovered that one enantiomer of a chiral substrate can greatly enhance the fluorescence of one molecular probe at one emitting signal (λ1 = 517 nm), while the opposite enantiomer of the substrate greatly enhances the fluorescence of the same probe at a distinctively different emission (λ2 = 575 nm). This probe is made of a 1,1'-binaphthyl-based chiral dialdehyde that in combination with Zn2+ under slightly acidic conditions shows a chemoselective and enantioselective fluorescent response to histidine. The opposite enantioselective fluorescent responses of the probe at two emissions allow it to be used to determine both the concentration and the enantiomeric composition of the substrate using a single probe. The mechanistic study has revealed two very different reaction pathways when the two enantiomers of the substrate are treated with the probe. These reaction pathways generate two different products, one dimeric and another polymeric, with very different emissions.

Abstract
Purpose: Disparities in the diagnosis and treatment of patients with differentiated thyroid cancer (DTC) have been described. This review includes the most recent literature on existing diagnostic and treatment disparities in the United States and proposes practical clinical and policy ideas for improving the gap in the treatment of DTC. Methodology: We performed a comprehensive literature review to include key articles related to DTC and disparities of treatment, diagnosis, and outcomes for disadvantaged patient populations. Results: Vulnerable patient populations with DTC have been extensively studied, and the literature shows that clear disparities of diagnosis and treatment exist. Socioeconomically disadvantaged patients, uninsured, rural, elderly, and patients belonging to minoritized racial and ethnic groups are more likely to present with advanced disease at presentation. These same vulnerable patient populations are less likely to have access to high-volume surgeons, less likely to be treated according to guidelines, and receive less aggressive treatment (such as radioactive iodine) compared with white patients. Further, these patients experience financial toxicity more so than their counterparts. Conclusions: Disparities of care exist for certain vulnerable patient populations with DTC. Approaches to rectify these should be multipronged and involve improving access to high-volume specialists with ongoing use of telehealth consults, language concordant care, an emphasis on guideline-directed therapies, ensuring continuity of care and long-term follow-up with better community partnerships, engage diverse patients in national guideline-writing committees of prominent societies and reducing the financial burden of cancer treatments at the state and national policy level.

Abstract
Quantitatively assessing the level of confidence on a test score can be a challenging problem, especially when the available information is based on multiple criteria. A concrete example beyond the usual grading of tests occurs with recommendation letters, where a recommender assigns a score to a candidate, but the reliability of the recommender must be assessed as well. Here, we present a statistical procedure, based on Bayesian inference and Jaynes' maximum entropy principle, that can be used to estimate the most probable and expected score given the available information in the form of a credible interval. Our results may provide insights on how to properly state and analyze problems related to the uncertain evaluation of performance in learning applied to several contexts, beyond the case study of the recommendation letters presented here.

Abstract
Abstract
Background
Patients with anorexia nervosa (AN) are at higher risk of sudden cardiac death. Although the underlying aetiology for this association remains unclear. It may be related to prolongation of the QT interval, which can degenerate into fatal ventricular arrhythmias. However, the presence of prolonged heart rate-corrected QT interval (QTc) in AN remains controversial, and two previous meta-analyses on AN and QTc showed contradictory findings [1,2].
Purpose
In this systematic review and meta-analysis, we aimed to evaluate if AN was associated with changes in the QTc interval and dispersion.
Methods
MEDLINE, EMBASE and COCHRANE databases were systematically searched from inception to January 2021. Random-effects meta-analysis and meta-regression were used. The inclusion criteria were (i) confirmed diagnosis of AN, (ii) measurement of QTc on electrocardiogram and (iii) peer-reviewed articles. The primary endpoint of the study was the duration of the QTc interval calculated using the Bazett (QTcB), Hodges (QTcH), Fridericia (QTcF) and Framingham (QTcFr) formulae. The secondary endpoints were QT dispersion (QTd) and QTc dispersion (QTcd).
Results
The 25 eligible studies included 5687 patients (1862 AN, 3825 control) (Figure 1: PRISMA diagram). The majority of patients were female (96.3%) with a mean age between 14.3 to 31.0 years and mean duration of disease ranging from 9.1 to 129.6 months. The mean BMI ranged from 13.7 to 18.5 kg/m2. Pooled analysis did not show significant prolongation between AN versus control in QTcB (mean difference (MD) MD 4.9ms, 95% CI −3.2, 13.1ms, p=0.23; I2=95%; n=24/25 studies; Figure 2A), QTcH (MD 1.3ms, 95% CI −8.5, 11.2ms, p=0.79; I2=71%; n=3/25 studies), and QTcF (MD 3.1ms, 95% CI −21.6, 27.7ms, p=0.81; I2=97%; n=3/25 studies). Only two studies reporting QTcFr showed a significant prolongation between AN and control (MD 15.9ms, 95% CI 0.0, 31.8ms, p=0.05, I2=65%; n=2/25 studies; Figure 2B). However, QTd and QTcd were significantly greater in AN than control (MD 21.3ms, 95% CI 10.4, 32.3ms, p=0.0001, I2=94%; Figure 2C and MD 16.9ms, 95% CI 4.5, 29.3ms, p=0.007 I2=93%; Figure 2D, respectively).
Conclusion
To the best of our knowledge, this is the largest meta-analysis of QTc in AN and the first meta-analysis exploring the significance of QTd and QTcd in AN. AN was not found to be associated with prolongation of QTc calculated using the Bazett, Fridericia and Hodges formulae. However, an association of AN with prolonged QTc was observed in the studies using the Framingham formula. More pronounced dispersion (QTd and QTcd) was also observed in patients with AN.

Abstract
BACKGROUND The 2015 American Thyroid Association guidelines recommended either total thyroidectomy or lobectomy for surgical treatment of low-risk differentiated thyroid cancer and de-escalated recommendations for central neck dissections. The study aim was to investigate how practice patterns among endocrine surgeons have changed over time. METHODS All adult patients with low-risk differentiated thyroid cancers (T1-T2, N0/Nx, M0/Mx) in the Collaborative Endocrine Surgery Quality Improvement Program (2014-2021) were identified. The outcomes between patients undergoing lobectomy versus total thyroidectomy were compared using multivariable logistic regression. The annual percent change in the proportion of lobectomies and central neck dissections performed was estimated using joinpoint regression. RESULTS In total, 5,567 patients with low-risk differentiated thyroid cancers were identified. Of these, 2,261 (40.6%) were very low-risk tumors ≤1 cm, and 2,983 (53.6%) were low-risk tumors >1 and <4 cm. Most patients (67.9%) underwent total thyroidectomy. Compared to total thyroidectomy, lobectomy was associated with outpatient surgery (adjusted odds ratio 5.19, P < .001), a decreased risk of postoperative emergency department visits (adjusted odds ratio 0.63, P = .03), and decreased risk of hypoparathyroidism events (adjusted odds ratio 0.03, P < .001). Compared to before (2014-2015), patients undergoing surgery after publication of the revised guidelines (2016-2021) had higher odds of lobectomy and lower odds of central neck dissection for tumors ≤1 cm (lobectomy adjusted odds ratio 2.70, P < .001; central neck dissections adjusted odds ratio 0.64, P = .03) and tumors between 1 and 4 cm (lobectomy adjusted odds ratio 2.27, P < .001; central neck dissection adjusted odds ratio 0.62, P < .001). CONCLUSION After publication of the 2015 American Thyroid Association guidelines, there has been an increase in thyroid lobectomies as a proportion of all thyroid operations performed by endocrine surgeons for low-risk differentiated thyroid cancer. This has implications for reduced health care use and costs, with potential population-level benefits.

Abstract
Abstract
Genomic and adaptive determinants of organ-specific metastasis are poorly understood. A model of sequential acquisition of divergent somatic mutations is insufficient to explain metastasis. Liver metastasis (LM) occurs frequently and is associated with a poor prognosis and reduced therapy response in several cancers, including in patients with melanoma and lung cancer. To identify drivers of metastatic niches, we used a syngeneic mouse melanoma model which recapitulates genomic, metastatic and therapy response patterns seen in patients. We performed a large-scale in vivo CRISPR-Cas9 knockout screen and identified perturbations that promote LM, but not primary tumor growth or metastasis to other organs (e.g. lung). The “top hit” in this screen associated with LM was loss Pip4k2c. We generated Pip4k2cKO cells and show that in otherwise isogenic melanoma cell lines, loss of Pip4k2c led to increased baseline and insulin-induced activation of the PI3K/AKT pathway, and increased invasive capacity. Rescuing Pip4k2cKO with full-length (Pip4k2cRec) or allosteric domain deficient (Pip4k2cAD) Pip4k2c ORFs, we show that hyperactivation of the PI3K/AKT pathway in is mediated by loss of the allosteric domain function, and not loss of the kinase domain of Pip4k2c. Treatment with different PI3K inhibitors effectively abrogated the pathway, but was partly bypassed in the presence of insulin in Pip4k2cKO and Pip4k2cAD, but not parental or Pip4k2cRec cells. Upon tail vein injection, Pip4k2cKO cells produced a significantly increased LM burden compared to parental cells, and this effect was rescued in Pip4k2cRec but not Pip4k2cAD, further affirming that loss of allosteric domain was required for this phenotype. We reasoned that Pip4k2cKO cells preferentially colonized the liver by co-opting the insulin-rich milieu in this organ. To test this, we used shRNA targeted against the insulin receptor (Insr) generated Pip4k2cKO/InsrshIR and showed that Insr was required but not sufficient to enhance LM burden. Given the promising in vitro activity of PI3K inhibitors, we next tested whether these could abrogate LM in vivo. Surprisingly, we found a substantial increase in LM burden in mice with Pip4k2cKO-bearing LM treated with PI3K inhibition compared to vehicle treated animals. We show that this paradoxical observation was due to host-mediated increased in glucose and insulin in response to PI3K inhibitor, which promoted a forward loop of increased liver metastasis. Breaking this loop with either ketogenic diet or treatment with a SGLT2 inhibitor in turn rescued increased these host responses and resulted in reduced LM burden in combination with PI3K inhibition. In summary, we identify a novel mechanism of metastatic liver organotropism and pharmacological and dietary combinations to reduced liver metastatic burden. Given the expanding use of PI3K inhibitors, our findings may have important clinical implications.

Abstract
Introduction Voluntary medical male circumcision (VMMC) uptake has been slow in some countries, including Botswana. To inform demand creation efforts, we examined sociodemographic characteristics and referral procedures associated with VMMC uptake in the Botswana Combination Prevention Project (BCPP) and examined the effectiveness of referral of men to MC services from HIV testing venues. Design BCPP was a community-randomized trial evaluating the impact of a combination HIV prevention package which included VMMC on community HIV incidence. We conducted a sub-analysis of VMMC uptake in intervention communities. Methods During the initial VMMC campaign in 15 intervention communities, baseline male circumcision (MC) status was assessed among men eligible for HIV testing. Uncircumcised male community residents aged 16–49 years with negative/unknown HIV status were mobilized and linked to study VMMC services. Outcomes included MC baseline status and uptake through study services. Univariate and multivariate logistic regressions were performed to identify factors associated with MC uptake. Results Of 12,864 men eligible for testing, 50% (n = 6,448) were already circumcised. Among the uncircumcised men (n = 6,416), 10% (n = 635) underwent MC. Of the 5,071 men identified as eligible for MC through HIV testing services, 78% declined referral and less than 1% of those were circumcised. Of those accepting referral (n = 1,107), 16% were circumcised. Younger (16–24 years) (aOR: 1.51; 95%CI:1.22,1.85), unemployed men (aOR:1.34; 95%CI: 1.06,1.69), and those undergoing HIV testing at mobile venues (aOR: 1.88; 95%CI: 1.53,2.31) were more likely to get circumcised. Fear of pain was the most prevalent (27%) reason given for not being circumcised. Conclusion Younger, unemployed men seeking HIV testing at mobile sites in Botswana were more likely to get VMMC. Addressing unique barriers for employed and older men may be necessary. Given the simplicity of VMMC as an intervention, the HIV testing programs offer a platform for identifying uncircumcised men and offering information and encouragement to access services.

Abstract
PURPOSE A significant barrier to adoption of de-escalated treatment protocols for human papillomavirus-driven oropharyngeal cancer (HPV-OPC) is that few predictors of poor prognosis exist. We conducted the first large whole-genome sequencing (WGS) study to characterize the genetic variation of the HPV type 16 (HPV16) genome and to evaluate its association with HPV-OPC patient survival. PATIENTS AND METHODS A total of 460 OPC tumor specimens from two large United States medical centers (1980-2017) underwent HPV16 whole-genome sequencing. Site-specific variable positions [single nucleotide polymorphisms (SNPs)] across the HPV16 genome were identified. Cox proportional hazards model estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for overall survival by HPV16 SNPs. Harrell C-index and time-dependent positive predictive value (PPV) curves and areas under the PPV curves were used to evaluate the predictive accuracy of HPV16 SNPs for overall survival. RESULTS A total of 384 OPC tumor specimens (83.48%) passed quality control filters with sufficient depth and coverage of HPV16 genome sequencing to be analyzed. Some 284 HPV16 SNPs with a minor allele frequency ≥1% were identified. Eight HPV16 SNPs were significantly associated with worse survival after false discovery rate correction (individual prevalence: 1.0%-5.5%; combined prevalence: 15.10%); E1 gene position 1053 [HR for overall survival (HRos): 3.75, 95% CI 1.77-7.95; Pfdr = 0.0099]; L2 gene positions 4410 (HRos: 5.32, 95% CI 1.91-14.81; Pfdr = 0.0120), 4539 (HRos: 6.54, 95% CI 2.03-21.08; Pfdr = 0.0117); 5050 (HRos: 6.53, 95% CI 2.34-18.24; Pfdr = 0.0030), and 5254 (HRos: 7.76, 95% CI 2.41-24.98; Pfdr = 0.0030); and L1 gene positions 5962 (HRos: 4.40, 95% CI 1.88-10.31; Pfdr = 0.0110) and 6025 (HRos: 5.71, 95% CI 2.43-13.41; Pfdr = 0.0008) and position 7173 within the upstream regulatory region (HRos: 9.90, 95% CI 3.05-32.12; Pfdr = 0.0007). Median survival time for patients with ≥1 high-risk HPV16 SNPs was 3.96 years compared with 18.67 years for patients without a high-risk SNP; log-rank test P < 0.001. HPV16 SNPs significantly improved the predictive accuracy for overall survival above traditional factors (age, smoking, stage, treatment); increase in C-index was 0.069 (95% CI 0.019-0.119, P < 0.001); increase in area under the PPV curve for predicting 5-year survival was 0.068 (95% CI 0.015-0.111, P = 0.008). CONCLUSIONS HPV16 genetic variation is associated with HPV-OPC prognosis and can improve prognostic accuracy.

Abstract
BACKGROUND Bisphosphonates are effective in preventing fragility fractures; however, high rates of adherence are needed to preserve clinical benefits. OBJECTIVE To investigate persistence and compliance to oral and intravenous bisphosphonates (alendronate, ibandronate, risedronate, and zoledronate). METHODS Searches of 12 databases, unpublished sources, and trial registries were conducted, covering the period from 2000 to April 2021. Screening, data extraction, and risk of bias assessment (Cochrane Collaboration risk-of-bias tool 1.0 & ROBINS-I) were independently undertaken by two study authors. Randomised controlled trials (RCTs) and observational studies that used prescription claim databases or hospital medical records to examine patients' adherence were included. Network meta-analyses (NMA) embedded within a Bayesian framework were conducted, investigating users' likelihood in discontinuing bisphosphonate treatment. Where meta-analysis was not possible, data were synthesised using the vote-counting synthesis method. RESULTS Fifty-nine RCTs and 43 observational studies were identified, resulting in a total population of 2,656,659 participants. Data from 59 RCTs and 24 observational studies were used to populate NMAs. Zoledronate users were the least likely to discontinue their treatment HR = 0.73 (95%CrI: 0.61, 0.88). Higher rates of compliance were observed in those receiving intravenous treatments. The paucity of data and the heterogeneity in the reported medication possession ratio thresholds precluded a NMA of compliance data. CONCLUSIONS Users of intravenously administered bisphosphonates were found to be the most adherent to treatment among bisphosphonates' users. Patterns of adherence will permit the more precise estimation of clinical and cost-effectiveness of bisphosphonates. TRIAL REGISTRATION PROSPERO 2020 CRD42020177166.

Abstract
PURPOSE In Sheffield (UK), we introduced the PINP monitoring algorithm for the management of osteoporosis treatment delivered in primary care. Our aims were to evaluate whether this algorithm was associated with better osteoporosis outcomes and was cost-effective compared to standard care. METHODS Inclusion criteria were referral from Sheffield GPs, BMD scans performed between 2012 and 2013 and a report advising initiation of oral bisphosphonate and PINP monitoring. 906 patients were identified and retrospectively divided into Group A (intention to monitor, with baseline PINP, n = 588) and Group B (no intention to monitor, without baseline PINP, n = 318). The model described by Davis and colleagues was used to extrapolate life-time costs and quality-adjusted life-years (QALYs). RESULTS No differences were found in baseline characteristics between groups (age, gender, BMI, BMD and major risk factors for fractures). More patients in Group A started oral treatment (77.4% vs 49.1%; p < 0.001), but there were no differences between groups in the presence of a gap in treatment >3 months or in treatment duration. Patients in Group A were more likely to have follow-up DXA scan at 4-6 years from baseline (46.9% vs 29.2%; p < 0.000) and had a greater increase in total hip BMD (+2.74% vs + 0.42%; p value = 0.003). Fewer new fractures occurred in Group A but this was not statistically significant, but the numbers of fractures were small. Patients in Group A were more likely to change management (p = 0.005) including switching to zoledronate (p = 0.03). The PINP measurement and increased prescribing in Group A resulted in increases in both costs (£30.19) and QALYs (0.0039) relative to Group B, giving an incremental cost effectiveness ratio (ICER) of £7660 in the probabilistic sensitivity analysis. CONCLUSIONS Patients monitored with PINP are more likely to start oral bisphosphonate treatment, switch to zoledronate, have follow-up DXA scans and a greater increase of hip BMD. PINP monitoring has the potential to be cost-effective in a UK NHS setting given that interventions with an ICER under £20,000 are generally considered to be cost-effective.

Abstract
Integrating primary care with the health response is key to managing pandemics and other health emergencies. In recognition of this, the Australian Government established a network of respiratory clinics led by general practitioners in response to the coronavirus disease 2019 (COVID-19) pandemic as part of broader measures aimed at supporting primary care. General practitioner (GP) respiratory clinics provide holistic face-to-face assessment and treatment to those with respiratory symptoms in an environment with strict protocols for infection prevention and control. This ensures that these patients are able to access high quality primary care while protecting the general practice workforce and other patients. The GP respiratory clinic model was developed and operationalized 10 days after the policy was announced, with the first 2 respiratory clinics opening on March 21, 2020. Subsequently a total of 150 respiratory clinics were opened and served over 800,000 patients within more than 99% of Australia's postcodes. These clinics used a standardized data collection tool that has provided the largest and most complete primary care surveillance database of respiratory illness in Australia. The success of the GP respiratory clinic model was made possible due to strong partnerships with Primary Health Networks and individual general practices that rapidly shifted operations to embrace this new approach. This article describes the development and early implementation of this model.

Abstract
Effective control of coronavirus disease 2019 (COVID-19) has been challenging, in part due to significant asymptomatic and pre-symptomatic transmission of disease. Reducing the time between symptom onset and COVID-19 testing and isolation allows enhanced outbreak control. The purpose of this study is to describe the time taken by participants to present to general practitioner-led (GP) respiratory clinics for assessment following the development of symptoms, and to explore associations between demographic and geographic characteristics and the time to presentation. A total of 314,148 participants, who were assessed in GP respiratory clinics between 1 February and 31 August 2021, were included in the analysis. The median age of participants at presentation was 33 years (interquartile range, IQR: 15-49). The median time from development of symptoms to presentation for assessment at GP respiratory clinics was 2 days (IQR: 1-3). Participants were more likely to present within one day of symptom onset if they were aged between 15 and 64 years (43.4%), lived in urban areas (40.9%) or were non-Indigenous (40.2%). Participants in New South Wales and Victoria had twice the odds (OR 2.01; 95% confidence interval (CI): 1.95, 2.08) of presenting at a GP respiratory clinic within one day of symptom onset in August 2021, when there was a COVID-19 outbreak in those states, than they did in March 2021, when there was no COVID-19 outbreak in Australia. The number of days from symptom onset to presentation at a GP respiratory clinic was strongly associated with the presence of a COVID-19 outbreak. Participant age, location of the clinic, and Indigenous status of participants were also associated with the time to presentation. This study highlights the importance of recognising COVID-19 as a potential cause of symptoms, as well as the importance of providing easily accessible, and culturally appropriate, testing facilities for the population.

Abstract
The urgency of the COVID-19 pandemic in Australia has seen the implementation of digital health technologies to support continuity of high-quality primary care provision. Digital health innovation has been used to operationalise the nation's pandemic preparedness principles by reducing risk of infection to both healthcare workers and at-risk patients, sustaining care for chronic and acute health conditions, and supporting the mental health of the population. In this perspective piece, we document the Australian Federal government's digital health response to ensure the ongoing delivery of high-quality primary care. This includes the implementation of telehealth, point-of-care testing, electronic records and e-prescriptions, national primary care data collection and analysis, and digital communication. Digital health has been a critical element of the pandemic response and paves the way for future primary care provision during disasters and emergencies. Further research is needed to capture the effectiveness, feasibility and acceptability of these innovations for both patients and primary care practitioners.

Abstract
COVID-19 continues to exact a toll on human health despite the availability of several vaccines. Bacillus Calmette Guérin (BCG) has been shown to confer heterologous immune protection against viral infections including COVID-19 and has been proposed as vaccine against SARS-CoV-2 (SCV2). Here we tested intravenous BCG vaccination against COVID-19 using the golden Syrian hamster model together with immune profiling and single cell RNA sequencing (scRNAseq). We observed that BCG reduced both lung SCV2 viral load and bronchopneumonia. This was accompanied by an increase in lung alveolar macrophages, a reversal of SCV2-mediated T cell lymphopenia, and reduced lung granulocytes. Single cell transcriptome profiling showed that BCG uniquely recruits immunoglobulin-producing plasma cells to the lung suggesting accelerated antibody production. BCG vaccination also recruited elevated levels of Th1, Th17, Treg, CTLs, and Tmem cells, and differentially expressed gene (DEG) analysis showed a transcriptional shift away from exhaustion markers and towards antigen presentation and repair. Similarly, BCG enhanced lung recruitment of alveolar macrophages and reduced key interstitial macrophage subsets, with both cell-types also showing reduced IFN-associated gene expression. Our observations indicate that BCG vaccination protects against SCV2 immunopathology by promoting early lung immunoglobulin production and immunotolerizing transcriptional patterns among key myeloid and lymphoid populations.

Abstract
BACKGROUND Down syndrome (DS) is associated with elevated rates of autism spectrum disorder (ASD) and autism symptomatology. To better characterise heterogeneity in ASD symptomatology in DS, profiles of caregiver-reported ASD symptoms were modelled for children and adolescents with DS. METHODS Participants (n = 125) were recruited through several multi-site research studies on cognition and language in DS. Using the Social Responsiveness Scale-2 (SRS-2; Constantino and Gruber 2012), two latent profile analyses (LPA) were performed, one on the broad composite scores of social communication and interaction and restricted interests and repetitive behaviour, and a second on the four social dimensions of social communication, social motivation, social awareness, and social cognition. RESULTS A three-profile model was the best fit for both analyses, with each analysis yielding a low ASD symptom profile, an elevated or mixed ASD symptom profile and a high ASD symptom profile. Associations were observed between profile probability scores and IQ, the number of co-occurring biomedical conditions reported, sex, and SRS-2 form. CONCLUSIONS Characterising heterogeneity in ASD symptom profiles can inform more personalised supports in this population, and implications for potential therapeutic approaches for individuals with DS are discussed.

Abstract
Institutional racism exists within Academic Pediatrics within the United States, and it affects our work as researchers, clinicians, and educators. Confronting institutional racism is a challenging life-long struggle for people of all races, but it should be part of the professional mission of all who work in Pediatrics. Creating a path to health equity for children in the United States will involve failure. We should not be daunted by that prospect.

Abstract
This meta-narrative review on mental health early intervention support for LGBTQ+ youth aimed to develop a theoretical framework to explain effective mental health support. Using the RAMESES standards for meta-narrative reviews, we identified studies from database searches and citation-tracking. Data extraction and synthesis was conducted through conceptual coding in Atlas.ti. in two stages: 1) conceptual mapping of the meta-narratives; 2) comparing the key concepts across the meta-narratives to produce a theoretical framework. In total, 2951 titles and abstracts were screened and 200 full papers reviewed. 88 studies were included in the final review. Stage 1 synthesis identified three meta-narratives - psychological, psycho-social, and social/youth work. Stage 2 synthesis resulted in a non-pathological theoretical framework for mental health support that acknowledged the intersectional aspects of LGBTQ+ youth lives, and placed youth at the centre of their own mental health care. The study of LGBTQ+ youth mental health has largely occurred independently across a range of disciplines such as psychology, sociology, public health, social work and youth studies. The interdisciplinary theoretical framework produced indicates that effective early intervention mental health support for LGBTQ+ youth must prioritise addressing normative environments that marginalises youth, LGBTQ+ identities and mental health problems. Despite elevated rates of poor mental health, LGBTQ + youth underutilize mental health services and often experience inadequate support. There is a limited evidence-base examining LGBTQ + youth early intervention mental health support needs. Early intervention services for LGBTQ + youth mental health must de-pathologize emotional distress, difficult thoughts and behaviours. Early intervention support must address normative environments that marginalises youth, intersectional LGBTQ + identities and mental health. Mental health support providers must understand individual lives, connect with LGBTQ+ youth, facilitate their autonomy and encourage agency.

Abstract
Background Effective syndromic surveillance alongside COVID-19 testing behaviours in the population including in higher risk and hard to reach subgroups is vital to detect re-emergence of COVID-19 transmission in the community. The aim of this paper was to identify the prevalence of acute respiratory infection symptoms and coronavirus testing behaviour among South Australians using data from a population based survey. Methods We used cross-sectional data from the 2020 state-wide population level health survey on 6857 respondents aged 18 years and above. Descriptive statistics were used to explore the risk factors and multivariable logistic regression models were used to assess the factors associated with the acute respiratory infection symptoms and coronavirus testing behaviour after adjusting for gender, age, household size, household income, Aboriginal and/or Torres Strait Islander status, SEIFA, Country of birth, number of chronic diseases, wellbeing, psychological distress, and mental health. Results We found that 19.3% of respondents reported having symptoms of acute respiratory infection and the most commonly reported symptoms were a runny nose (11.2%), coughing (9.9%) and sore throat (6.2%). Fever and cough were reported by 0.8% of participants. Of the symptomatic respondents, 32.6% reported seeking health advice from a nurse, doctor or healthcare provider. Around 18% (n = 130) of symptomatic respondents had sought testing and a further 4.3% (n = 31) reported they intended to get tested. The regression results suggest that older age, larger household size, a higher number of chronic disease, mental health condition, poor wellbeing, and psychological distress were associated with higher odds of ARI symptoms. Higher household income was associated with lower odds of being tested or intending to be tested for coronavirus after adjusting for other explanatory variables. Conclusions There were relatively high rates of self-reported acute respiratory infection during a period of very low COVID-19 prevalence and low rate of coronavirus testing among symptomatic respondents. Ongoing monitoring of testing uptake, including in higher-risk groups, and possible interventions to improve testing uptake is key to early detection of disease.

Abstract
BACKGROUND COVID-19 is the fifth and most significant infectious disease epidemic this century. Primary health care providers, which include those working in primary care and public health roles, have critical responsibilities in the management of health emergencies. OBJECTIVE To synthesize accounts of primary care lessons learnt from past epidemics and their relevance to COVID-19. METHODS We conducted a review of lessons learnt from previous infectious disease epidemics for primary care, and their relevance to COVID-19. We searched PubMed/MEDLINE, PROQUEST and Google Scholar, hand-searched reference lists of included studies, and included research identified through professional contacts. RESULTS Of 173 publications identified, 31 publications describing experiences of four epidemics in 11 countries were included. Synthesis of findings identified six key lessons: (i) improve collaboration, communication and integration between public health and primary care; (ii) strengthen the primary health care system; (iii) provide consistent, coordinated and reliable information emanating from a trusted source; (iv) define the role of primary care during pandemics; (v) protect the primary care workforce and the community and (vi) evaluate the effectiveness of interventions. CONCLUSIONS Evidence highlights distinct challenges to integrating and supporting primary care in response to infectious disease epidemics that have persisted over time, emerging again during COVID-19. These insights provide an opportunity for strengthening, and improved preparedness, that cannot be ignored in a world where the frequency, virility and global reach of infectious disease outbreaks are increasing. It is not too soon to plan for the next pandemic, which may already be on the horizon.

Abstract
Abstract
Aim
VTE prophylaxis is a vital aspect of patient safety. The decision whether to offer pharmacological thromboprophylaxis is a balance of risk versus benefit. There is a low incidence of VTE in ENT patients, admissions are often short and active bleeding on admission is not uncommon (epistaxis patients, already on anticoagulation are particularly difficult to manage}. There are no clear, specialty specific guidelines to assist in these frequently encountered endeavours.
Method
The number of emergency ENT admissions who had a documented VTE during admission or in the 28 days following was used to calculate the incidence of VTE in acute admissions. An audit of VTE prophylaxis and documentation was also conducted using 20 admissions over 24 hours.
Results
Incidence was 0.12%. 75% had a documented VTE risk assessment. Only 50% patients were prescribed chemical and mechanical thromboprophylaxis. 0% had appropriately documented that the patient did not require thromboprophylaxis on the drug chart (as per trust guidelines).
Conclusions
The results showed that both documentation and prescribing related to VTE prevention were poor. By highlighting the low incidence amongst this patient group, we were able to establish clearer guidance for VTE prophylaxis in acute ENT admissions and a protocol to standardise the management of anticoagulation in actively bleeding epistaxis patients.

Abstract
BACKGROUND Understanding and improving obstetrical quality and safety is an important goal of professional societies, and many interventions such as checklists, safety bundles, educational interventions, or other culture changes have been implemented to improve the quality of care provided to obstetrical patients. Although many factors contribute to delivery decisions, a reduced workload has addressed how provider issues such as fatigue or behaviors surrounding impending shift changes may influence the delivery mode and outcomes. OBJECTIVE The objective was to assess whether intrapartum obstetrical interventions and adverse outcomes differ based on the temporal proximity of the delivery to the attending's shift change. STUDY DESIGN This was a secondary analysis from a multicenter obstetrical cohort in which all patients with cephalic, singleton gestations who attempted vaginal birth were eligible for inclusion. The primary exposure used to quantify the relationship between the proximity of the provider to their shift change and a delivery intervention was the ratio of time from the most recent attending shift change to vaginal delivery or decision for cesarean delivery to the total length of the shift. Ratios were used to represent the proportion of time completed in the shift by normalizing for varying shift lengths. A sensitivity analysis restricted to patients who were delivered by physicians working 12-hour shifts was performed. Outcomes chosen included cesarean delivery, episiotomy, third- or fourth-degree perineal laceration, 5-minute Apgar score of <4, and neonatal intensive care unit admission. Chi-squared tests were used to evaluate outcomes based on the proportion of the attending's shift completed. Adjusted and unadjusted logistic models fitting a cubic spline (when indicated) were used to determine whether the frequency of outcomes throughout the shift occurred in a statistically significant, nonlinear pattern RESULTS: Of the 82,851 patients eligible for inclusion, 47,262 (57%) had ratio data available and constituted the analyzable sample. Deliveries were evenly distributed throughout shifts, with 50.6% taking place in the first half of shifts. There were no statistically significant differences in the frequency of cesarean delivery, episiotomy, third- or fourth-degree perineal lacerations, or 5-minute Apgar scores of <4 based on the proportion of the shift completed. The findings were unchanged when evaluated with a cubic spline in unadjusted and adjusted logistic models. Sensitivity analyses performed on the 22.2% of patients who were delivered by a physician completing a 12-hour shift showed similar findings. There was a small increase in the frequency of neonatal intensive care unit admissions with a greater proportion of the shift completed (adjusted P=.009), but the findings did not persist in the sensitivity analysis. CONCLUSION Clinically significant differences in obstetrical interventions and outcomes do not seem to exist based on the temporal proximity to the attending physician's shift change. Future work should attempt to directly study unit culture and provider fatigue to further investigate opportunities to improve obstetrical quality of care, and additional studies are needed to corroborate these findings in community settings.

Abstract
BACKGROUND Levocarnitine deficiency has been observed in patients receiving parenteral nutrition (PN) and can cause or worsen hypertriglyceridemia. The objective was to characterize use of levocarnitine supplementation in PN and evaluate its effect on triglyceride levels in hospitalized adults. METHODS This retrospective, single-center study included patients with triglyceride levels ≥175 mg/dl while receiving PN who had a subsequent reduction in lipid injectable emulsion dose. A piecewise linear regression was used to evaluate trends in triglyceride levels before and after the intervention, defined as initiation of levocarnitine in PN for the levocarnitine group, or reduction in lipid injectable emulsion alone for the control group. RESULTS Two hundred sixty-one patients who received PN had an elevated triglyceride level and lipid injectable emulsion dose reduction, of which 97 (37.2%) received levocarnitine in PN. The median (IQR) levocarnitine dose added to PN was 8.0 (5.7-9.9) mg/kg. Triglyceride levels at 30 days post-intervention did not differ between groups (125 vs 176 mg/dl, P = .345). The addition of levocarnitine to PN was associated with a significantly greater rate of reduction in triglyceride levels pre-intervention to post-intervention compared with a reduction in lipid injectable emulsion alone (-11 vs -3 mg/dl per day; 95% CI, -15 to -2; P = .012). CONCLUSION In hospitalized adults with hypertriglyceridemia who had a lipid injectable emulsion dose reduction, the addition of levocarnitine in PN was not associated with a difference in triglyceride levels at 30 days; however, a greater rate of improvement in pre-intervention to post-intervention triglyceride levels was observed.

Abstract
Introduction Kenya started implementing voluntary medical male circumcision (VMMC) for HIV prevention in 2008 and adopted the use of decision makers program planning tool version 2 (DMPPT2) in 2016, to model the impact of circumcisions performed annually on the population prevalence of male circumcision (MC) in the subsequent years. Results of initial DMPPT2 modeling included implausible MC prevalence estimates, of up to 100%, for age bands whose sustained high uptake of VMMC pointed to unmet needs. Therefore, we conducted a cross-sectional survey among adolescents and men aged 10–29 years to determine the population level MC prevalence, guide target setting for achieving the goal of 80% MC prevalence and for validating DMPPT2 modelled estimates. Methods Beginning July to September 2019, a total of 3,569 adolescents and men aged 10–29 years from households in Siaya, Kisumu, Homa Bay and Migori Counties were interviewed and examined to establish the proportion already circumcised medically or non-medically. We measured agreement between self-reported and physically verified circumcision status and computed circumcision prevalence by age band and County. All statistical were test done at 5% level of significance. Results The observed MC prevalence for 15-29-year-old men was above 75% in all four counties; Homa Bay 75.6% (95% CI [69.0–81.2]), Kisumu 77.9% (95% CI [73.1–82.1]), Siaya 80.3% (95% CI [73.7–85.5]), and Migori 85.3% (95% CI [75.3–91.7]) but were 0.9–12.4% lower than DMPPT2-modelled estimates. For young adolescents 10–14 years, the observed prevalence ranged from 55.3% (95% CI [40.2–69.5]) in Migori to 74.9% (95% CI [68.8–80.2]) in Siaya and were 25.1–32.9% lower than DMMPT 2 estimates. Nearly all respondents (95.5%) consented to physical verification of their circumcision status with an agreement rate of 99.2% between self-reported and physically verified MC status (kappa agreement p-value<0.0001). Conclusion This survey revealed overestimation of MC prevalence from DMPPT2-model compared to the observed population MC prevalence and provided new reference data for setting realistic program targets and re-calibrating inputs into DMPPT2. Periodic population-based MC prevalence surveys, especially for established programs, can help reconcile inconsistencies between VMMC program uptake data and modeled MC prevalence estimates which are based on the number of procedures reported in the program annually.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE Speech language pathology (SLP) is an underutilized but important component in rehabilitation after tracheostomy. The purpose of this study was to determine rates of SLP utilization and to streamline tracheostomy decannulation to be more efficient and safer through increased utilization of SLP. METHODS Adult patients who underwent tracheostomy from April 2016 to December 2018 were evaluated. The primary outcome was completion of any SLP evaluation after tracheostomy, and secondary outcomes were duration from surgery to evaluation, speaking valve and swallow study utilization, downsize and decannulation rates, mean duration of cannulation, and complications. RESULTS A total of 255 subjects were included, where 197 (77.3%) underwent SLP evaluation. A minority received a speaking valve (33.7%), while approximately half underwent a swallow study (52.9%). There was a delay in SLP evaluation, with mean duration from surgery to SLP evaluation of 5.9 ± 8.0 days. There was consistent improvement in downsize and decannulation rates in all cohorts that utilized SLP services. Tracheostomy indication of head and neck cancer, trauma, completing a successful swallow study conferred increased odds of eventual decannulation, while obesity and tracheostomy history conferred lower odds. An interdisciplinary decannulation pathway was created, based on literature review and results, to assist in decision-making while progressing toward decannulation. CONCLUSION Speech language pathologists are underutilized for rehabilitation of tracheostomy patients, where they are able to offer many skills to diagnose, treat, manage, and troubleshoot, as patients advance through the decannulation process.

Abstract
Introduction Internationally the COVID-19 pandemic has triggered a dramatic and unprecedented shift in telehealth uptake as a means of protecting healthcare consumers and providers through remote consultation modes. Early in the pandemic, Australia implemented a comprehensive and responsive set of policy measures to support telehealth. Initially targeted at protecting vulnerable individuals, including health professionals, this rapidly expanded to a “whole population” approach as the pandemic evolved. This policy response supported health system capacity and community confidence by protecting patients and healthcare providers; creating opportunities for controlled triage, remote assessment and treatment of mild COVID-19 cases; redeploying quarantined or isolated health care workers (HCWs); and maintaining routine and non-COVID healthcare. Purpose This paper provides a review of the literature regarding telephone and video consulting, outlines the pre-COVID background to telehealth implementation in Australia, and describes the national telehealth policy measures instituted in response to COVID-19. Aligned with the existing payment system for out of hospital care, and funded by the national health insurance scheme, a suite of approximately 300 temporary telehealth Medicare-subsidised services were introduced. Response to these initiatives was swift and strong, with 30.01 million services, at a cost of AUD $1.54 billion, claimed in the first six months. Findings This initiative has been a major policy success, ensuring the safety of healthcare consumers and healthcare workers during a time of great uncertainty, and addressing known financial risks and barriers for health service providers. The risks posed by COVID-19 have radically altered the value proposition of telehealth for patients and clinicians, overcoming many previously encountered barriers to implementation, including willingness of clinicians to adopt telehealth, consumer awareness and demand, and the necessity of learning new ways of conducting safe consultations. However, ensuring the quality of telehealth services is a key ongoing concern. Conclusions Despite a preference by policymakers for video consultation, the majority of telehealth consults in Australia were conducted by telephone. The pronounced dominance of telephone item numbers in early utilisation data suggests there are still barriers to video-consultations, and a number of challenges remain before the well-described benefits of telehealth can be fully realised from this policy and investment. Ongoing exposure to a range of clinical, legislative, insurance, educational, regulatory, and interoperability concerns and solutions, driven by necessity, may drive changes in expectations about what is desirable and feasible – among both patients and clinicians.

Abstract
Epidurals are considered the gold standard for labour analgesia. The possibility of newer pumps reducing staff workload has reignited interest in the advantages of the intermittent bolus technique, but is this superior to a continuous epidural infusion?

Abstract
Water Quality issues in many Pacific countries are rising, with the increase in coastal populations and associated urban runoff but management requires contamination issues in the aquatic environment to be identified and prioritised. In Vanuatu and Solomon Islands there are few laboratories and resources to assess for the presence or impact of complex chemical contaminants. The extent and impact of chemical contamination of the marine and coastal environment is poorly described. Passive chemical samplers were used to measure a range of aquatic pollutants around the capital cities, Honiara (Solomon Islands) and Port Vila (Vanuatu). We detected a range of chemicals indicative of agricultural and industrial contamination and a few sites had concerning concentrations of specific hydrocarbons and pesticides. The rapid ecotoxicology test, Microtox, indicated toxic impacts in rivers, coastal sites and urban drains This work provides new data on chemical contamination and possible impacts of that contamination for both countries. The techniques could be applied widely across the region to generate critical data for environmental management, guide monitoring efforts and measure the impact of policy or land-use changes.
