Abstract
PURPOSE The health care industry is an inherently resource-intense sector. Emerging technologies such as artificial intelligence (AI) are at the forefront of advancements in health care. The health economic implications of this technology have not been clearly established and represent a substantial barrier to adoption both in Australia and globally. This review aims to determine the health economic impact of implementing AI to ophthalmology in Australia. METHODS A systematic search of the databases PubMed/MEDLINE, EMBASE, and CENTRAL was conducted to March 2022, before data collection and risk of bias analysis in accordance with preferred reporting items for systematic ceviews and meta-analyses 2020 guidelines (PROSPERO number CRD42022325511). Included were full-text primary research articles analyzing a population of patients who have or are being evaluated for an ophthalmological diagnosis, using a health economic assessment system to assess the cost-effectiveness of AI. RESULTS Seven articles were identified for inclusion. Economic viability was defined as direct cost to the patient that is equal to or less than costs incurred with human clinician assessment. Despite the lack of Australia-specific data, foreign analyses overwhelmingly showed that AI is just as economically viable, if not more so, than traditional human screening programs while maintaining comparable clinical effectiveness. This evidence was largely in the setting of diabetic retinopathy screening. CONCLUSIONS Primary Australian research is needed to accurately analyze the health economic implications of implementing AI on a large scale. Further research is also required to analyze the economic feasibility of adoption of AI technology in other areas of ophthalmology, such as glaucoma and cataract screening.

Abstract
Background Androgenetic alopecia (AGA) is the most common cause of hair loss, often challenging to treat. While oral finasteride (1 mg/day) is an FDA-approved treatment for male AGA, oral minoxidil and oral dutasteride are not approved yet. However, clinicians have been increasingly using these two drugs off-label for hair loss. Recently, Japan and South Korea have approved oral dutasteride (0.5 mg/day) for male AGA.Efficacy and safety A probable efficacy ranking, in decreasing order, is- dutasteride 0.5 mg/day, finasteride 5 mg/day, minoxidil 5 mg/day, finasteride 1 mg/day, followed by minoxidil 0.25 mg/day. Oral minoxidil predominantly causes hypertrichosis and cardiovascular system (CVS) symptoms/signs in a dose-dependent manner, whereas oral finasteride and dutasteride are associated with sexual dysfunction and neuropsychiatric side effects.Pharmacokinetics and pharmacodynamics The average plasma half-lives of minoxidil, finasteride, and dutasteride are ∼4 hours, ∼4.5 hours, and ∼5 weeks, respectively. Minoxidil acts through multiple pathways to promote hair growth. It has been shown as a vasodilator, an anti-inflammatory agent, a Wnt/β-catenin signaling inducer, and an antiandrogen. Finasteride inhibits 5 α-reductase (5AR) type II isoenzyme, while dutasteride inhibits both type I and type II. Thus, dutasteride suppresses DHT levels more than finasteride in the serum and scalp.

Abstract
IMPORTANCE Small study effects are the phenomena that studies with smaller sample sizes tend to report larger and more favorable effect estimates than studies with larger sample sizes. OBJECTIVE To evaluate the presence and extent of small study effects in diagnostic imaging accuracy meta-analyses. DATA SOURCES A search was conducted in the PubMed database for diagnostic imaging accuracy meta-analyses published between 2010 and 2019. STUDY SELECTION Meta-analyses with 10 or more studies of medical imaging diagnostic accuracy, assessing a single imaging modality, and providing 2 × 2 contingency data were included. Studies that did not assess diagnostic accuracy of medical imaging techniques, compared 2 or more imaging modalities or different methods of 1 imaging modality, were cost analyses, used predictive or prognostic tests, did not provide individual patient data, or were network meta-analyses were excluded. DATA EXTRACTION AND SYNTHESIS Data extraction was performed in accordance with the PRISMA guidelines. MAIN OUTCOMES AND MEASURES The diagnostic odds ratio (DOR) was calculated for each primary study using 2 × 2 contingency data. Regression analysis was used to examine the association between effect size estimate and precision across meta-analyses. RESULTS A total of 31 meta-analyses involving 668 primary studies and 80 206 patients were included. Fixed effects analysis produced a regression coefficient for the natural log of DOR against the SE of the natural log of DOR of 2.19 (95% CI, 1.49-2.90; P < .001), with computed tomography as the reference modality. Interaction test for modality and SE of the natural log of DOR did not depend on modality (Wald statistic P = .50). Taken together, this analysis found an inverse association between effect size estimate and precision that was independent of imaging modality. Of 26 meta-analyses that formally assessed for publication bias using funnel plots and statistical tests for funnel plot asymmetry, 21 found no evidence for such bias. CONCLUSIONS AND RELEVANCE This meta-analysis found evidence of widespread prevalence of small study effects in the diagnostic imaging accuracy literature. One likely contributor to the observed effects is publication bias, which can undermine the results of many meta-analyses. Conventional methods for detecting funnel plot asymmetry conducted by included studies appeared to underestimate the presence of small study effects. Further studies are required to elucidate the various factors that contribute to small study effects.

Abstract
BACKGROUND Microwaves are used in medicine for diagnostics, and treatment of cancer. Recently, novel microwave devices (Swift®, Emblation Ltd, UK and miraDry®, Miramar Labs Inc., CA) have been cleared by the FDA and Health Canada for various dermatological conditions. OBJECTIVE AND METHODS To review the dermatological use of microwave-based treatments (plantar warts, corns, actinic keratosis, dermatophytosis, axillary hyperhidrosis, osmidrosis, and hidradenitis suppurativa). Clinical trials, case reports, or in vitro studies for each condition are summarized. RESULTS AND CONCLUSION Microwaves are a promising alternative therapy for cutaneous warts, actinic keratosis, axillary hyperhidrosis, and osmidrosis, with favorable safety profiles. However, patients with hidradenitis suppurativa have had negative clinical outcomes. Limited treatment of corns showed good pain reduction but did not resolve hyperkeratosis. A preliminary in vitro study indicated that microwave treatment inhibits the growth of T. rubrum. We present the first case of toenail onychomycosis successfully treated with microwaves. Despite the advancements in the use of microwaves, the mechanism of action in non-ablative treatment is not well understood; further research is needed. More high-quality randomized clinical trials with larger groups and long follow-up periods are also required to evaluate the clinical benefits and possible adverse effects of microwaves in treating dermatological conditions.

Abstract
INTRODUCTION Patients commonly use YouTube for education, and this may have increased due to COVID-19 related restrictions on access to healthcare professionals. However, YouTube videos lack peer review and regulation. To assess patient education in the COVID-19 era, we analyzed the quality of YouTube videos on coronary artery bypass graft (CABG) surgery. METHODS We searched YouTube using the phrase "coronary artery bypass graft." Two authors individually used the Journal of the American Medical Association (JAMA), DISCERN, and Health on the Net (HON) systems, to rate the first 50 videos retrieved. Data collected for each video included; number of views, duration since upload, percentage positivity (proportion of likes relative to total likes plus dislikes), number of comments, and video author. Interobserver reliability was assessed using an intraclass correlation coefficient (ICC). Associations between video characteristics and quality were tested using linear regression or t-tests. RESULTS The average number of views was 575,571. Average quality was poor, with mean scores of 1.93/4 (ICC 0.54) for JAMA criteria, 2.52/5 (ICC 0.78) for DISCERN criteria, and 4.04/8 (ICC 0.66) for HON criteria. Videos uploaded by surgeons scored highest overall (p < .05). No other factors demonstrated significant association with video quality. CONCLUSION YouTube videos on CABG surgery are of poor quality and may be inadequate for patient education. Given the complexity of the procedure and that beyond the COVID-19 era, patients are more likely to seek education from digital sources, treating surgeons should advise of YouTube's limitations and direct patients to reliable sources of information.

Abstract
Introduction The COVID‐19 pandemic has had a significant impact on global surgery. In particular, deleterious effects of SARS‐CoV‐2 infection on the heart and cardiovascular system have been described. To inform surgical patients, we performed a systematic review and meta‐analysis aiming to characterize outcomes of COVID‐19 positive patients undergoing cardiac surgery. Methods The study protocol was registered with PROSPERO (CRD42021228533) and conformed with PRISMA 2020 and MOOSE guidelines. PubMed, Ovid MEDLINE and Web of Science were searched between 1 January 2019 to 24 February 2022 for studies reporting outcomes on COVID‐19 positive patients undergoing cardiac surgery. Study screening, data extraction and risk of bias assessment were conducted in duplicate. Meta‐analysis was conducted using a random‐effects model where at least two studies had sufficient data for that variable. Results Searches identified 4223 articles of which 18 studies were included with a total 44 patients undergoing cardiac surgery. Within these studies, 12 (66.7%) reported populations undergoing coronary artery bypass graft (CABG) surgery, three (16.7%) aortic valve replacements (AVR) and three (16.7%) aortic dissection repairs. Overall mean postoperative length of ICU stay was 3.39 (95% confidence interval (CI): 0.38, 6.39) and mean postoperative length of hospital stay was 17.88 (95% CI: 14.57, 21.19). Conclusion This systematic review and meta‐analysis investigated studies of limited quality which characterized cardiac surgery in COVID‐19 positive patients and demonstrates that these patients have poor outcomes. Further issues to be explored are effects of COVID‐19 on decision‐making in cardiac surgery, and effects of COVID‐19 on the cardiovascular system at a cellular level.

Abstract
PURPOSE Early weight bearing (EWB) is often recommended after intramedullary nailing of tibial shaft fractures, however, the risks and benefits have not been critically evaluated in a systematic review or meta-analysis. Therefore, the aims of this study were to perform a systematic review and meta-analysis comparing EWB and delayed weight-bearing (DWB) after intramedullary nailing of tibial shaft fractures and assess the relationship between weight-bearing, fracture union and healing. METHOD This review included studies comparing the effects of EWB, defined as weight-bearing before 6 weeks, and DWB on fracture union and healing. PubMed, Embase, CINAHL, and the Cochrane Library were searched from inception to 9 May 2021. Risk of bias was assessed using the Down's and Black Checklist and Cochrane Risk of Bias Tool 2.0. Data were synthesised in a meta-analysis, as well as narrative and tabular synthesis. RESULTS Eight studies were included for data extraction and meta-analysis. The analysis produced mixed results and found a significant decrease in mean union time (-2.41 weeks, 95% confidence interval: -4.77, -0.05) with EWB and a significant Odd's Ratio (OR) for complications with DWB (OR: 2.93, 95% CI: 1.40, 6.16). There was no significant difference in rates of delayed union, non-union, re-operation and malunion. CONCLUSION The included studies were of moderate risk of bias and demonstrated shorter union time and fewer complications with EWB. However, current evidence is minimal and has significant limitations. The role of EWB in high-risk patients is yet to be examined. Further well-designed, randomised studies are required on the topic.

Abstract
Extracorporeal Membrane Oxygenation (ECMO) was first used in the 1970s. Its use is increasingly common in critical care and perioperative settings and has gained newfound prominence during COVID-19. To guide future research, we conducted a bibliometric analysis of ECMO literature. Thomson Reuters Web of Science was searched to March 7, 2021. Articles were ranked by total number of citations. Data was extracted from the 100 most cited papers relevant to ECMO for study design, topic, author, year, and institution. Journal impact factor for 2019 and Eigenfactor scores were also recorded. Our search retrieved a total of 18,802 articles. Median number of citations for the top 100 articles was 220 (range 157-1,819). These were published in 34 journals, with first authors originating from 15 countries. The Annals of Thoracic Surgery had the highest number of articles (n = 9) while Lancet publications had the most citations (n = 3,191). Use of ECMO was most commonly observed in cardiogenic shock or acute respiratory distress syndrome. United States had the greatest article output (n = 49). With 10 publications, 2013 was the most prolific year. Using linear regression, when controlled for time since publication, there was no statistically significant relationship between 2019 journal impact factor and number of article citations (p = .09). Top articles in the ECMO literature are of considerable impact and quality. As the United States produced the bulk of the prominent evidence base, and most data were regarding respiratory issues, outsized advances in ECMO may be possible within the United States during the COVID-19 era.

Abstract
INTRODUCTION Gastrointestinal recovery after surgery is of worldwide significance. Postoperative gastrointestinal dysfunction is multifaceted and known to represent a major source of postoperative morbidity, however, its significance to postoperative care across all surgical procedures is unknown. The complexity of postoperative gastrointestinal recovery is poorly defined within gastrointestinal surgery, and even less so outside this field. To inform the clinical care of surgical patients worldwide, this systematic review and meta-analysis will aim to characterise the duration of postoperative gastrointestinal recovery that can be expected across all surgical procedures and determine the associations between factors that may affect this. METHODS AND ANALYSIS MEDLINE, Embase, Cochrane Library and CINAHL will be searched for studies reporting the time to first postoperative passage of stool after any surgical procedure. We will screen records, extract data and assess risk of bias in duplicate. Forest plots will be constructed for time to postoperative gastrointestinal recovery, as assessed by various outcome measures. Because of potential heterogeneity, a random-effects model will be used throughout the meta-analysis. Funnel plots will be used to test for publication bias. Meta-regressions will be undertaken where the outcome is the mean time to first postoperative passage of stool, with potential predictors and confounders being patient characteristics, postoperative outcomes and surgical factors. ETHICS AND DISSEMINATION This study will not involve human or animal subjects and, thus, does not require ethics approval. The outcomes will be disseminated via publication in peer-reviewed scientific journal(s) and presentations at scientific conferences. PROSPERO REGISTRATION NUMBER CRD42021256210.

Abstract
BACKGROUND The coronavirus-19 (COVID-19) pandemic has affected millions of people across the world since early 2020. Besides the large number of case fatalities, this virus has produced significant health-related sequelae involving multiple systems of the body. As with previous coronavirus infections, this was also found to be associated with various neuropsychiatric symptoms. Psychosis has been uncommon, and the few reported cases across the world have forwarded association with either raised inflammatory markers or the consequences of social isolation. MATERIALS AND METHODS This is a retrospective descriptive study of 12 patients, who were admitted with COVID-19 infection and psychosis, between March 2020 and December 2020. Cases of head injury, any neurological or metabolic illnesses, and substance use disorders were excluded. RESULTS Cases with psychosis formed only 0.19% of all cases of COVID-19 admissions. All of them were young male and employed. Most of them had abrupt onset of psychosis with confusion, delusions, hallucinations, agitation, and sleep disturbances. Investigations including inflammatory markers (C-reactive protein) and computerized tomography scans were largely normal. Medications used were mainly benzodiazepines and antipsychotics. Most of the cases resolved within the second week, and follow-up after a month did not elicit any residual symptoms in majority. Diagnosis was acute and transient psychotic disorder (about 75%), bipolar affective disorder (2 cases), and schizophrenia (one). CONCLUSIONS The major findings included nonreactive inflammatory markers, quick resolution of symptoms, requirement of low doses of antipsychotic drugs, and no long-term sequelae.

Abstract
Purpose: To compare observation versus subthreshold green laser (STL) in acute central serous chorioretinopathy (CSC) in terms of anatomical and functional outcomes. Methods: Prospective randomized interventional study. 30 eyes with the first episode of acute CSC underwent complete ophthalmologic examination, measurement of best-corrected Snellen visual acuity (BCVA), contrast sensitivity (CS), fundus fluorescein angiography (FFA), spectral-domain optical coherence tomography (SD-OCT), and multifocal electroretinography (mfERG) at baseline. Patients were randomized equally to group A (observation) or group B (STL using 532 nm wavelength applied to the leakage point). Outcome measures included BCVA, CS, central foveal thickness (CFT), and mean macular thickness (MMT) on SD-OCT and P1 amplitude and implicit time (IT) on mfERG. Patients were followed up for 6 months. Results: Mean BCVA was comparable between the two groups on follow up; however, mean CS was significantly higher in group B at 6 months (P = 0.032). CFT was significantly lower in group B at 1 month (P = 0.001) and 3 months (P = 0.049); however, this difference was not maintained at 6 months (P = 0.265). P1 amplitude and IT in all 5 rings were comparable between the two groups at baseline. On follow up, P1 amplitude of ring 1 became significantly higher in group B at 3 months (P = 0.036) and 6 months (P = 0.022). Conclusion: Immediate treatment of acute CSC with STL, as compared to conservative management, leads to more rapid resolution on SD-OCT and superior functional outcomes as evidenced by CS and mfERG.

[PMID: 34363891 DOI: 10.1016/j.jdent.2021.103771] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 07/14/2021] [Accepted: 07/30/2021] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVE Psychological research has established that the presence of dental anomalies negatively impact social judgements. This study sought to determine the effects of tooth colour on the subjective ratings of social judgements in a group of Caucasian adults. METHODS A cross sectional experimental analogue design comprised fifty Caucasian adults: 25 women and 25 men. A total of 54 digitally modified photographs of Caucasian males and females (darkened, natural, whitened teeth) were evaluated. All participants evaluated each of the images on 12 characteristics: popularity, friendliness, social life, success, graduation, happiness, intelligence, perceived age, introversion/extraversion, self-confidence, attractiveness and satisfaction with the tooth shade. Analysis of variance (ANOVA) was used to compare ratings. RESULTS Participants associated darkened teeth with poorer subjective ratings, with the highest ratings been given to whitened teeth, and natural teeth being intermediate. These trends were similar across all participant age groups and gender. Further, the gender and age groups of the images had a significant effect on the appraisals. Faces of younger models received higher ratings than the faces of older models and female images were rated higher than the males. CONCLUSION In the absence of other information, tooth colour exerts an influence upon the appraisals made in social situations. It appears that whitened tooth appearance is preferred to natural tooth appearance, irrespective of age and gender of the judge. The faces with more whitened dentition are perceived to be younger across all age groups and gender of the judges. Participants dissatisfied with their own tooth shade drew out more stereotypic behaviour. CLINICAL SIGNIFICANCE STATEMENT This research used standardised tooth colour as a basis to investigate perceived age and social functioning. As clinicians face daily challenges to achieve patient satisfaction with respect to dental aesthetics, standardizing the colour may enhance the patients' satisfaction. Further, participants dissatisfied with their own tooth shade drew out more stereotypic behaviour. The whitened dentition may impair the psychological well-being of the individuals and is probably a reason for the increasing demand for cosmetic dental procedures. These results may be instructive for the development of a psycho-educational intervention to prevent any unrealistic expectations.

Abstract
BACKGROUND AND OBJECTIVES Finasteride 1 mg/day is indicated for androgen-dependent conditions such as male androgenetic alopecia (AGA). METHODS The literature is comprehensively summarized on the pharmacodynamics, pharmacokinetics, mechanism of action, and metabolism of finasteride. Pairwise and network meta-analyses were performed to assess the efficacy of finasteride reported in clinical trials. The adverse events profile is described along with the post-marketing reports. RESULTS AND CONCLUSION Finasteride 1 mg/day significantly increased total hair count compared to placebo after 24 weeks (mean difference = 12.4 hairs/cm2, p < .05), and 48 weeks (mean difference = 16.4 hairs/cm2, p < .05). The efficacy of the two doses of finasteride (5 mg/day and 1 mg/day) and topical finasteride (1% solution) were not significantly different. The most commonly reported sexual events include erectile dysfunction and decreased libido. Increasing patient complaints and analysis of the FAERS database led to the inclusion of depression in the FDA label in 2011, as men were found to be at a risk of suicide due to the persistent sexual side effects, commonly termed as post-finasteride syndrome. Finasteride is shown to be reasonably tolerated in both men and women; however, patients need to be educated about the possible short- and long-term side-effects.
