RESUMO
OBJECTIVE: Patients with Huntington's disease can present with variable difficulties of motor functioning, mood, and cognition. Neurodegeneration occurs in the anterior cingulate cortex of some patients with Huntington's disease and is linked to the presentation of mood symptomatology. Neuroinflammation, perpetrated by activated microglia and astrocytes, has been reported in Huntington's disease and may contribute to disease progression and presentation. This study sought to quantify the density of mutant huntingtin protein and neuroinflammatory glial changes in the midcingulate cortex of postmortem patients with Huntington's disease and determine if either correlates with the presentation of mood, motor, or mixed symptomatology. METHODS: Free-floating immunohistochemistry quantified 1C2 immunolabeling density as an indicative marker of mutant huntingtin protein, and protein and morphological markers of astrocyte (EAAT2, Cx43, and GFAP), and microglial (Iba1 and HLA-DP/DQ/DR) activation. Relationships among the level of microglial activation, mutant huntingtin burden, and case characteristics were explored using correlative analysis. RESULTS: We report alterations in activated microglia number and morphology in the midcingulate cortex of Huntington's disease cases with predominant mood symptomatology. An increased proportion of activated microglia was observed in the midcingulate of all Huntington's disease cases and positively correlated with 1C2 burden. Alterations in the astrocytic glutamate transporter EAAT2 were observed in the midcingulate cortex of patients associated with mood symptoms. INTERPRETATION: This study presents pathological changes in microglia and astrocytes in the midcingulate cortex in Huntington's disease, which coincide with mood symptom presentation. These findings further the understanding of neuroinflammation in Huntington's disease, a necessary step for developing inflammation-targeted therapeutics. ANN NEUROL 2023;94:895-910.

OBJECTIVE: To establish whether time to exercise cessation using the Buffalo Concussion Treadmill Test (BCTT) protocol can be used as a prognostic indicator of recovery after sport-related mild traumatic brain injury (SR-mTBI). DESIGN: Retrospective analysis of prospectively collected data. SETTING: Specialist Concussion Clinic. PARTICIPANTS: Three hundred and twenty one patients presenting between 2017 and 2019 who underwent BCTT for SR-mTBI. INTERVENTIONS: Participants who remained symptomatic at a 2-week follow-up appointment after SR-mTBI underwent BCTT to develop a progressive subsymptom threshold exercise program with fortnightly follow-up until clinical recovery. MAIN OUTCOME MEASURES: Clinical recovery was the primary outcome measure. RESULTS: A total of 321 participants were eligible to participate in this study (mean age 22.94% and 46% female). The BCTT test duration was divided into 4-minute intervals and those who completed full 20 minutes. There was higher probability of clinical recovery in those who finished the entire 20-minute BCTT protocol compared with those who managed 17-<20 minutes (Hazard Ratio, HR 0.57), 13 to 16 minutes (HR 0.53), 9 to 12 minutes (HR 0.6), 5 to 8 minutes (HR 0.4), and 1 to 4 minutes (HR 0.7), respectively. Those seen earlier after injury ( P = 0.009), male patients ( P = 0.116), younger patients ( P = 0.0003), and those with physiological or cervical dominant ( P = 0.416) symptom clusters were more likely to achieve clinical recovery. Fifty percent of those who completed the full BCTT protocol achieved clinical recovery at day 19 post-injury. CONCLUSIONS: The group completing full 20 minutes of BCTT achieved clinical recovery more quickly than those who did not complete full BCTT.

BACKGROUND: Rheumatic fever is an autoimmune condition that occurs in response to an untreated Group A Streptococcus throat or skin infection. Recurrent episodes of rheumatic fever can cause permanent damage to heart valves, heart failure and even death. Maori and Pacific people in Aotearoa New Zealand experience some of the highest rates globally, with Pacific children 80 times more likely to be hospitalised for rheumatic fever and Maori children 36 times more likely than non-Maori, non-Pacific children. Community members from the Pacific People's Health Advisory Group, research officers from the Pacific Practice-Based Research Network and University of Auckland researchers identified key health priorities within the South Auckland community that needed to be addressed, one of which was rheumatic fever. The study outlined in this protocol aims to co-design, implement, and evaluate a novel intervention to reduce rheumatic fever rates for Pacific communities in South Auckland. METHODS: This participatory mixed-methods study utilises the Fa'afaletui method and follows a three-phase approach. Phase 1 comprises a quantitative analysis of the rheumatic fever burden within Auckland and across New Zealand over the last five years, including sub-analyses by ethnicity. Phase 2 will include co-design workshops with Pacific community members, families affected by rheumatic fever, health professionals, and other stakeholders in order to develop a novel intervention to reduce rheumatic fever in South Auckland. Phase 3 comprises the implementation and evaluation of the intervention. DISCUSSION: This study aims to reduce the inequitable rheumatic fever burden faced by Pacific communities in South Auckland via a community-based participatory research approach. The final intervention may guide approaches in other settings or regions that also experience high rates of rheumatic fever. Additionally, Maori have the second-highest incidence rates of rheumatic fever of all ethnic groups, thus community-led approaches 'by Maori for Maori' are also necessary. TRIAL REGISTRATION: The Australian New Zealand Clinical Trial Registry has approved the proposed study: ACTRN12622000565741 and ACTRN12622000572763 .

BACKGROUND: Buttabean Motivation (BBM) is a Pacific-led organisation which aims to reduce obesity amongst Pacific and Maori people in New Zealand enabling them to choose a healthy and active life-style for the duration of their lives, their children, their wider family and the community. BBM offers a holistic approach to weight loss, recognising that mental health, family and cultural factors all play essential and critical role in nutrition and physical activity patterns. This study aims to evaluate the effectiveness of BBM for sustained health and wellbeing outcomes among its predominantly Pacific and Maori participants for both general BBM members and those with morbid obesity attending the 'From the Couch' programme. METHODS: Quasi-experimental pre-post quantitative cohort study design with measured or self-reported weight at various time intervals for both cohorts. Weight will be analysed with general linear mixed model for repeated measures, and compared with a prediction model generated from the literature using a mixed method meta-analysis. The secondary outcome is change in pre- and post scores of Maori scale of health and well-being, Hua Oranga. DISCUSSION: Multiple studies have shown that many diet and physical activity programmes can create short-term weight loss. The fundamental question is whether BBM members maintain weight loss over time. In New Zealand, Pacific and Maori engagement in health enhancing programmes remains an important strategy for achieving better health and wellbeing outcomes, and quality of life. Internationally, the collectivist cultures of indigenous and migrant and minority populations, living within dominant individualist western ideologies, have much greater burdens of obesity. If BBM members demonstrate sustained weight loss, this culturally informed community-based approach could benefit to other indigenous and migrant populations.

PURPOSE: Intuitive Eating (IE) is an approach to eating designed to facilitate a positive relationship with food. Its use in clinical settings and in the community is rapidly growing in popularity. The Intuitive Eating Scale 2 (IES-2) is a widely used measure that indexes intuitive eating motivations and behaviour, however evidence of its validity in populations with clinical eating disorders remains scarce. The objective of the proposed study was thus to evaluate the factor structure of the IES-2 in a large sample of individuals seeking treatment for eating disorders in private practice. METHODS: Data collected from 569 women and men aged 12-68 years seeking treatment for an eating disorder in one of eight specialist private outpatient eating disorder clinics were examined using confirmatory factor analysis (CFA). Relationships between IES-2 scores and measures of psychopathology were also examined. RESULTS: Results were relatively consistent with the purported four-factor structure of the IES-2. The measure displayed strong construct validity and good internal consistency. Scores on the IES-2 were inversely associated with scores of depression, anxiety, and disordered eating, providing evidence for divergent validity of the measure. Clinical norms are provided for anorexia nervosa (AN) spectrum disorders and bulimia nervosa (BN) spectrum disorders, as well as for the clinical sample as a whole. CONCLUSION: Findings suggest that the IES-2 may be an appropriate measure for evaluating behaviours relating to IE in community outpatient eating disorder settings, and provide further evidence for the association between IE and positive health outcomes. LEVEL OF EVIDENCE: III, evidence obtained from well-designed cohort or case-control analytic studies.

Keratoconus is primarily an anterior corneal disorder of unclear aetiology. Stem cells may play a role in the perpetuation of keratoconus, although this has yet to be definitively established. Sphere-forming cells from normal human donor corneas have previously been shown to be a heterogenous mix of epithelial, stromal, stem and progenitor cell components which have potential for treatment of corneal dystrophies. Our work set out to isolate and characterise sphere-forming cells from human keratoconic tissue. Keratoconic donor corneas were successfully used to culture sphere-forming cells in vitro. Time lapse imaging of these spheres on a collagen surface over 8 days revealed keratoconic spheres lack the ability to maintain a central core and have diminished ability to repopulate the surface. Immunocytochemistry showed positive labelling for the stem cell marker 'Adenosine triphosphate-binding cassette sub-family B member 5 (ABCB5)' indicating stem cell retention and the myofibroblast marker alpha smooth muscle actin indicating wound repair while droplet digital Polymerase Chain Reaction confirmed an increase in expression of stem and stromal cell markers in keratoconic spheres compared to spheres cultured from normal donors at day 7 post-placement. Keratoconic sphere-forming cells showed a diminished repopulation ability, a faster wound healing response and lack of central core retention. These results suggest stem cells in keratoconus may be in an elevated state of wound repair and unable to respond appropriately to further injury in corneal maintenance. Sphere forming cell populations in keratoconus appear to be different to those isolated from normal corneas and this may be an important consideration in unearthing keratoconus aetiology.

AIMS: This systematic review sought to synthesize the evidence regarding the effectiveness of illness perception interventions compared with control conditions at changing illness perceptions and improving glycaemic control in individuals with type 2 diabetes. METHODS: Seven electronic databases were searched between October 2018 and May 2020. Randomized controlled trials that tested interventions informed by the Common-Sense Model in adults with type 2 diabetes, and measured illness perceptions and glycaemic control at pre- and post-intervention were included. The Cochrane risk of bias tool was used to assess risk of bias. RESULTS: A total of 4095 articles were identified, of which nine randomized control trials (2561 participants) across 12 publications were included in this review. Findings showed that all the illness perception domains were modified in at least one trial, with the exception of cyclical timeline perceptions. Coherence, personal control, treatment control and chronic timeline perceptions were the most frequently modified perceptions. Glycaemic control demonstrated an improvement in the intervention group compared to the control group at 3 and 6 months post-intervention in two trials. Risk of bias assessment showed high risk of bias especially for the blinding of participants and the personnel domain. CONCLUSIONS: There is limited evidence that interventions informed by the Common-Sense Model can improve glycaemic control in individuals with type 2 diabetes through changing inaccurate illness perceptions. Recommendations for future research are to tailor intervention content based on baseline perceptions, measure the emotional and causal domains, and involve family members in the intervention.

BACKGROUND: Gout is a painful chronic disease which disrupts work and family life and can lead to chronic joint damage. Pacific people in Aotearoa/New Zealand experience significant inequities, with over three times the gout prevalence of the non-Pacific non-Maori populations. Pacific people receive less regular urate-lowering drugs to prevent gout flare-ups, and have nine times the hospitalisation from gout compared with non-Pacific non-Maori people. Rates for Indigenous Maori lie between Pacific and non-Pacific non-Maori. A long-established Collective comprising community members from the Pacific People's Health Advisory Group, clinical staff from the Pacific Practice-Based Research Network, and University of Auckland researchers have identified that improving Pacific urate-lowering therapy use as the research question of prime importance for improved health outcomes of Pacific people in South Auckland. Building on the existing knowledge, this study aims to develop, implement and evaluate a novel innovative intervention to improve the uptake of urate-lowering therapy by Pacific patients with gout. METHODS: Three-phase mixed methods co-design study using the Fa'afaletui research framework following the STROBE statement. Phase1 is observational times series of prevalence of patients with gout, proportion with urate blood-level monitoring and use of urate-lowering medication over past 5 years. In Phase 2 the Collective will workshop new interventions to address previous uptake barriers, using culturally-appropriate Talanga communications with results synthesised in line with Kakala principles. The designed intervention will be implemented and process and outcome evaluations conducted. Finally, an implementation framework will be produced to facilitate further roll-out. DISCUSSION: The study aims to enhance health and reduce inequities for Pacific people, contribute to creation of Pacific health knowledge and translation of research findings into Pacific health gains. Potential longer-term impact is a gout-management pathway for use throughout Aotearoa/New Zealand. Maori have similar issues with high gout prevalence and low urate-lowering therapy use hence the intervention is likely to translate to Maori healthcare. The project will contribute to Pacific research capacity and capability-building as well as general upskilling of community and practice members involved in the co-design processes. TRIAL REGISTRATION: The Australian New Zealand Clinical Trial Registry is in process, request number 38206, 1-09-2021.

AIM: Staphylococcus aureus (SA) causes serious invasive disease in children. Large studies have measured the incidence of SA bacteraemia, but there is less information on the total burden of community-acquired invasive SA (iSA) in children. METHODS: A retrospective, cross-sectional analysis of Auckland resident children aged 0-14 years who were hospitalised with iSA between 2011 and 2015 was performed. Laboratory databases and SA-related international classification of diseases 10 discharge codes were searched to identify community-onset cases with SA isolated from a normally sterile site. Clinical records and coroner's reports were reviewed to determine clinical syndromes and exclude nosocomial infections. RESULTS: A total of 295 children with iSA were identified. The average annual incidence of iSA was 18.6 per 100 000 - for Pacific populations 44.3 per 100 000, Maori 24.3 per 100 000 and New Zealand European and other 8.8 per 100 000; 68% had bacteraemia. The incidence of iSA for Pacific infants was 10 times greater than non-Maori/non-Pacific (113.4/100 000 population vs. 11.8/100 000). Multivariate analysis found a higher risk of admission in Pacific children, males and those living in areas of high deprivation. Thirty-two patients (10.8%) were admitted to the intensive care unit; risk was higher in infants, Pacific children and those with respiratory infection (Relative Risk (RR) 12.2, 95% confidence interval (CI) 5.7-26.4) and multifocal (RR 6.9, 95% CI 3.4-13.8) and endovascular disease (RR 8.9, 95% CI 3.9-20.6). All deaths (n = 7) had respiratory infections, and four were patients <1 year of age. CONCLUSIONS: Studies investigating SA bacteraemia alone significantly underestimate the total burden of iSA disease. There are marked ethnic and socio-economic disparities in iSA disease among Auckland children. Pacific infants are at the highest risk.

OBJECTIVE: Diabetic foot disease poses a significant and rising financial burden on health care systems worldwide. This study investigated the effect of a new multidisciplinary diabetic foot clinic (MDDFC) in a large tertiary hospital on patient outcomes and treatment cost. METHODS: Patients' records were retrospectively reviewed to identify all patients who had been managed in a new MDDFC between July 2014 and July 2017. The wound episode-the period from initial presentation to the achievement of a final wound outcome-was identified, and all relevant inpatient and outpatient costs were extracted using a fully absorbed activity-based costing methodology. Risk factor, treatment, outcome, and costing data for this cohort were compared with a group of patients with diabetic foot wounds who had been managed in the same hospital before the advent of the MDDFC using a generalized linear mixed model. RESULTS: The MDDFC and pre-MDDFC cohorts included 73 patients with 80 wound episodes and 225 patients with 265 wound episodes, respectively. Compared with the pre-MDDFC cohort, the MDDFC group had fewer inpatient admissions (1.56 vs 2.64; P ≤ .001). MDDFC patients had a lower major amputation rate (3.8% vs 27.5%; P ≤ .001), a lower mortality rate (7.5% vs 19.2%; P ≤ .05), and a higher rate of minor amputation (53.8% vs 31.7%; P ≤ .01). No statistically significant difference was noted in the rate of excisional débridement, skin graft, and open or endovascular revascularization. In the MDDFC cohort, the median total cost, inpatient cost, and outpatient cost per wound episode was New Zealand dollars (NZD) 22,407.465 (U.S. dollars [USD] 17,253.74), NZD 21,638.93 (USD 16,661.97), and NZD 691.915 (USD 532.77), respectively. The MDDFC to pre-MDDFC wound episode total cost ratio was 0.7586 (P < .001). CONCLUSIONS: This study is the first to compare the cost and treatment outcomes of diabetic foot patients treated in a large tertiary hospital before and after the introduction of an MDDFC. The results show that an MDDFC improves patient outcomes and reduces the cost of treatment. MDDFCs should be adopted as the standard of care for diabetic foot patients.

AIM: A retrospective Auckland-wide (total population approximately 1.4 million) study of hospital admissions from 2007 to 2015 was conducted to assess trends in admissions for acute post-streptococcal glomerulonephritis (APSGN) in children aged 0-14 years. METHODS: International Statistical Classification of Diseases (ICD10) discharge codes were used to identify potential cases of APSGN, and electronic clinical records and laboratory data were compared with established case definitions for definite or probable APSGN. RESULTS: A total of 430 cases of APSGN were identified (definite n = 337, probable n = 93), with a mean annual incidence of 15.2/100 000 (95% confidence interval (CI) 14.9-15.6). Incidence (0-14 years) was 17 times higher in Pacific peoples (50.2/100 000, 95% CI 48.6-51.8) and almost 7 times higher in Maori (19.6/100 000, 95% CI 18.6-20.7) than European/other populations (2.9/100 000, 95% CI 2.7-3.1). Multivariate analysis found ethnicity, deprivation, male gender, age (peak 3-8 years) and season (summer/autumn) to be associated with admission risk. Admission rates showed a significant change of -9.0% (95% CI -10.4, 7.4%) per year, with 2011 being an exception. Low C3 complement, hypertension, elevated streptococcal titres, oedema and heavy proteinuria were present in 94, 65, 67, 52 and 49% of cases, respectively. Relying on ICD10 codes without further review of clinical notes would result in an overcount of cases by 25%. CONCLUSIONS: There is severe disparity in APSGN admission rates, with a disproportionate burden of disease for Pacific and Maori children and those living in deprived circumstances. Rates trended downward from 2007 to 2015.

AIMS: New Zealand melanoma incidence rates are amongst the highest in the world. The study aims to provide information on the incidence of cutaneous melanoma in New Zealand from 2000 to 2022. METHODS: De-identified data were extracted from the New Zealand Cancer Registry using the ICD-10 code for malignant melanoma (C34) and melanoma in situ (MIS) (D03) from 2000 to 2022. Statistical analysis was performed to calculate melanoma incidence rates. RESULTS: Invasive melanoma (IM) incidence rates demonstrated an increasing trend from 2000 to 2008 (+1.10 per 100,000 person-years per year), followed by an inflection point at 2008 and then a decreasing trend from 2008 to 2022 (-0.28 per 100,000 person-years per year), which was not statistically different from zero/no change. MIS incidence increased from 30.3 to 72.1 per 100,000 person-years between 2000 and 2022. CONCLUSIONS: The incidence of IM in New Zealand has plateaued in the last decade and was associated with an increase in MIS incidence over the same period. While this trend is encouraging, further research is required to investigate whether there is an actual decline in IM incidence.

AIMS: We aimed to explore pharmacists' attitudes and support toward medically assisted dying (MaiD) through the End of Life Choice Act 2019 (EOLC), their willingness to provide services in this area of practice, and the influences on their decisions. METHODS: The study was conducted via an anonymous, online QualtricsTM survey of pharmacists. Registered New Zealand pharmacists who agreed to receive surveys from the two Schools of Pharmacy as part of their Annual Practicing Certificate renewal were invited to participate through an email with a Qualtrics URL link. The survey contained questions regarding demographics, awareness, knowledge, support for, and attitudes and willingness to participate. RESULTS: Of the 335 responses received, 289 were valid and included in the analysis. Most participants supported legally assisted medical dying (58%), almost a third of participants did not support it (29%), and 13% of respondents were unsure. The five primary considerations that participants perceived to be beneficial included support from legislation, respect for patient autonomy, discussions around morality, ending suffering, and preserving dignity. The main concerns were legal, personal bias, palliation, stigmatisation, and vulnerability. CONCLUSIONS: The influences on the decision by pharmacists to support and willingness to participate in the provision of services consistent with the EOLC are complex and multifactorial. Diverse factors may influence attitudes, of which religion is the most significant factor in not supporting the Act or willingness to participate. Clarity and standardised guidance to ensure that assisted dying queries are appropriately managed in practice would help to address any potential access issues.
RESUMO
BACKGROUND: Gender inequity continues to be a major focus of improvements within surgical education. Female trainees are fewer and experience reduced quality of surgical training. Prior studies have demonstrated that surgical autonomy for female trainees in a range of surgical disciplines is less than that of male trainees. As a unique example among Australasian specialty training boards, the New Zealand Board of Plastic and Reconstructive Surgery has boasted a gender-balanced cohort of surgical trainees since 2013. The authors sought to examine the effect of gender on surgical autonomy in a cohort of trainees where gender balance has been achieved. METHODS: A retrospective cohort study was undertaken. Anonymized logbook data for New Zealand plastic surgery trainees were analyzed, for the study period, consisting of rotations from December of 2013 to June of 2020. Self-reported levels of trainee supervision were compared against gender. Outcomes were tested using multivariate analysis. RESULTS: Thirty-eight trainees were included in the study (58% female), with a total of 81,178 cases recorded over the 6.5-year study period. No overall statistically significant difference in surgical autonomy was identified when analyzed by gender. Male and female trainees showed similar trends of increasing surgical autonomy throughout the course of surgical training. CONCLUSIONS: In a cohort of surgical trainees that has reached gender balance, the negative impact of gender on surgical autonomy was not identified. These findings suggest that where women make up an equal proportion of trainees, the implicit gender bias within surgical training may be ameliorated.

AIMS: Examine the access to the Bay of Plenty rehabilitation service for Indigenous Maori patients undergoing total knee arthroplasty (TKA). Identify structural aspects of the rehabilitation service which promote or restrict access for Maori. METHODS: All patients who underwent TKA in publicly funded Bay of Plenty hospitals in 2021 were retrospectively supplied with a survey. Participants were asked to self-report demographic information and to complete a structured record of the duration, type, and location of their pre and post-operative rehabilitation. RESULTS: Maori patients accessed more rehabilitation (mean = 9.75 total hours) than non-Maori patients (mean = 8.34 total hours). This was in large part driven by a significant home-based component of their rehabilitation (42.9% of Maori respondents received at least some of their rehabilitation at home, compared to 16.4% of non-Maori). CONCLUSIONS: Once engaged with the orthopaedic service and having undergone TKA, rehabilitation access for Maori is comparable to if not greater than that of non-Maori. This is in large part driven by home-based rehabilitation. Practical facilitators which negate transport and financial barriers are an effective method of promoting access to health services for Maori.

PURPOSE: Intuitive Eating (IE) is an approach to eating characterised by attunement to intrinsic cues, and using those cues to guide behaviours related to food and eating. Tylka and Kroon Van Diest's (2008) Intuitive Eating Scale (IES-2) is well-validated in adults, but not yet among early adolescents. The current study was designed to adapt and validate a version suited for use in early adolescence (IES-2-EA). METHODS: Data collected from two independent samples of adolescents aged 11 to 13 (N = 471) were structurally examined using exploratory factor analysis (EFA), with a subsequent confirmatory factor analysis (CFA) to confirm hypothesised model fit. Relationships between scores on the IES-2-EA and validated measures of actual-ideal body size discrepancy, body appreciation, interoceptive awareness, and psychological distress were also examined. RESULTS: The adapted 17-item IES-2-EA had a three-factor structure with several key differences from the original version developed for adults. Moderate-to-strong correlations were found between scores on the IES-2-EA, body appreciation, interoceptive awareness, actual-ideal body size discrepancy, and psychological distress in the first sample of adolescents (n = 245). Secondary CFA showed good model fit in the second sample of adolescents (n = 226). CONCLUSION: The IES-2-EA is well-suited to measure intuitive eating behaviour among early adolescents. The 17 items reflect a three-component structure similar to that seen in adults completing the IES-2. These early data suggest the adapted IES-2-EA has evidence of reliability and validity; it may be an effective measure for research and clinical use.

Importance: Surgical site infections (SSIs) represent a costly and preventable complication of cutaneous surgery. However, there is a paucity of randomized clinical trials investigating antibiotic prophylaxis for reducing SSIs in skin cancer surgery, and evidence-based guidelines are lacking. Incisional antibiotics have been shown to reduce the rate of SSIs before Mohs micrographic surgery, but this represents a small subset of skin cancer surgery. Objective: To determine whether microdosed incisional antibiotics reduce the rate of SSIs before skin cancer surgery. Design, Setting, and Participants: In this double-blind, controlled, parallel-design randomized clinical trial, adult patients presenting to a high-volume skin cancer treatment center in Auckland, New Zealand, for any form of skin cancer surgery over 6 months from February to July 2019 were included. Patient presentations were randomized to one of 3 treatment arms. Data were analyzed from October 2021 to February 2022. Interventions: Patients received an incision site injection of buffered local anesthetic alone (control), buffered local anesthetic with microdosed flucloxacillin (500 µg/mL), or buffered local anesthetic with microdosed clindamycin (500 µg/mL). Main Outcomes and Measures: The primary end point was the rate of postoperative SSI (calculated as number of lesions with SSI per total number of lesions in the group), defined as a standardized postoperative wound infection score of 5 or more. Results: A total of 681 patients (721 total presentations; 1133 total lesions) returned for postoperative assessments and were analyzed. Of these, 413 (60.6%) were male, and the mean (SD) age was 70.4 (14.8) years. Based on treatment received, the proportion of lesions exhibiting a postoperative wound infection score of 5 or greater was 5.7% (22 of 388) in the control arm, 5.3% (17 of 323) in the flucloxacillin arm, and 2.1% (9 of 422) in the clindamycin arm (P = .01 for clindamycin vs control). Findings were similar after adjusting for baseline differences among arms. Compared with lesions in the control arm (31 of 388 [8.0%]), significantly fewer lesions in the clindamycin arm (9 of 422 [2.1%]; P < .001) and flucloxacillin (13 of 323 [4.0%]; P = .03) arms required postoperative systemic antibiotics. Conclusions and Relevance: This study evaluated the use of incisional antibiotics for SSI prophylaxis in general skin cancer surgery and compared the efficacy of flucloxacillin vs clindamycin relative to control in cutaneous surgery. The significant reduction in SSI with locally applied microdosed incisional clindamycin provides robust evidence to inform treatment guidelines in this area, which are currently lacking.

OBJECTIVES: To systematically evaluates the evidence on ethnic differences in age-adjusted reference values of PSA. MATERIALS AND METHODS: In concordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement, a review of English articles using Medline, Embase and Cochrane databases, from inception to December 2019 was conducted. Studies that reported the PSA upper reference value as 95th percentile of the cohort distribution, in healthy men aged 40 to 79, were included. Methodological quality was assessed with a modified version of the Agency for Healthcare Research and Quality checklist for cross-sectional studies. RESULTS: Forty-three studies examining 325,514 participants were included in the analysis. These were published between 1993 and 2018. Majority were prospective observational studies and reported the reference values in ten-year age intervals. Only five reports directly compared ethnic differences in PSA values. Due to missing data, six studies were not considered in the quantitative synthesis. For the remainder (37/43), heterogeneity in PSA reference values was considerable (Higgin's index = 99.2%), with age and ethnicity being the sole identified significant contributors. Accordingly, the pooled upper limits for PSA reference values were 2.1, 3.2, 4.9 and 6.5 ng/ml for men in their 40 s, 50 s, 60 s, and 70 s, respectively. CONCLUSION: Moderate quality evidence suggest that upper PSA reference limits increased with age and significant ethnic differences were present.

(1) Background. Intravenous (IV) to oral switch (IVOS) of antibiotics can reduce the length of hospitalisation, risk of IV catheter complications, and hospital costs. Pharmacists can play an instrumental role in implementing an IVOS initiative. The aim of this study is to evaluate the impact of pharmacist-led IVOS of metronidazole. (2) Method. This was an observational study conducted in a New Zealand hospital. During a 3-month intervention period, pharmacists identified patients receiving IV metronidazole; then initiated an IVOS for patients who met the criteria. The comparator groups were patients who were not switched by pharmacists in the post-intervention (post-IVOS) group, or patients treated with either IV or oral metronidazole prior to the intervention (pre-IVOS). Primary outcome measures were switch rate and duration of IV metronidazole treatment. Secondary outcome measures were readmission and/or repeat surgery within 90 days of discharge and the length of hospital stay. (3) Results. In total, 203 patients were included: 100 in the pre-IVOS and 103 in the post-IVOS groups. Pharmacists switched 63/93 (67.7%) of eligible patients to oral metronidazole in the post-IVOS period. Only 9/89 (10.1%) of IVOS eligible patients were switched in the pre-IVOS group. In the post-IVOS group, the mean duration of IV metronidazole treatment in patients switched by pharmacists was shorter than in those who were not switched by pharmacists (2.5 ± 2.8 days vs. 4.8 ± 5.9 days, p = 0.012). No significant difference was found in readmission or repeat surgery within 90 days of discharge for patients switched by pharmacists versus patients who were not switched by pharmacists. (4) Conclusion. Our data have demonstrated successful implementation of the hospital-approved pharmacist-led IVOS service.
