Authors: Kim Celeste , Tran Erica , Kim Ian , Hur Kevin 
Published: November 2021

Objectives: To quantify national and state-level prescribing and cost trends for the 3 most prescribed nasal sprays by otolaryngologists in the Medicare population. Methods: Through the Centers for Medicare and Medicaid Services (CMS) database and the Kaiser Family Foundation, we retrieved data on Medicare enrollment and on claims and costs of fluticasone propionate, azelastine HCl, and ipratropium bromide prescribed by otolaryngologists from January 1, 2013 to December 31, 2017. Results: From 2013 to 2017, CMS reimbursed $128.8 million for 5.2 million claims of fluticasone propionate, azelastine HCl, and ipratropium bromide prescribed by otolaryngologists. The national claim rate for fluticasone propionate increased 6.5% per year from 2013 to 2015 and then decreased 4.3% per year from 2015 to 2017 while azelastine HCl and ipratropium bromide consistently increased annually (19.0% and 12.2% respectively) from 2013 to 2017. The cost for fluticasone propionate decreased 33.0% a year from 2013 to 2015 and then increased 5.4% annually to $13.60 per claim in 2017. Azelastine HCl decreased 14.8% annually from $91.30 to $50.23 per claim and ipratropium bromide increased 5.2% annually to $34.78 in 2017. Variations in the claim rate and cost for all 3 nasal sprays were observed in some states. Conclusions: Otolaryngologists are prescribing azelastine HCl and ipratropium at an increasingly higher rate in the Medicare population, while the rate for fluticasone propionate has been decreasing nationally. Utilization and costs of nasal sprays also vary geographically across the United States.

Background: The COVID-19 pandemic continues to be one of the greatest public health challenges faced by the UK. Reported rates of psychiatric difficulties have increased and the mechanisms by which the pandemic has affected mental health requires investigation. Aims: The aim of the study was to understand the psychological impact of the COVID-19 pandemic on health anxiety in the general population, with a focus on Oxford Health NHS Foundation Trust, which provides specialist mental health care within Oxfordshire and Buckinghamshire. Methods: We invited participants aged 18+ across Oxfordshire and Buckinghamshire to complete an online questionnaire consisting of standardised questionnaires measuring psychological wellbeing, non-standardised questions to provide demographic information, and information about social circumstances and behaviour during the COVID-19 pandemic. Participants were then invited via email to complete a 3-month follow-up questionnaire. Results: About 324 participants completed the baseline survey while 199 completed the follow-up. Our analysis demonstrated that higher scores on a health anxiety inventory were related to reports of depression, anxiety, loneliness, poor quality of life and obsessive-compulsive symptoms and panic. We also identified several predictors of health anxiety such as being female, having a pre-existing physical or mental health condition, and poor tolerance of uncertainty. Lifestyle and demographic factors such as changes in financial situation, changes in employment status, having a close relative or friend with COVID-19, being able to do grocery shopping, being a key worker, and ethnicity were not found to predict health anxiety. Conclusions: Awareness of the impact of health anxiety on people needs to be consistently high among healthcare professionals, especially in the continuing fallout from the COVID-19 pandemic. The relationship between health anxiety and fatigue, sleep quality, gender and co-morbid mental and physical health difficulties needs to be investigated further to determine areas of intervention.

Job satisfaction is determined as the measure to know the individuals’ feelings toward their work. The working conditions that can affect satisfaction and performance of the call center agents have received particular concern. This study aimed to determine the role of remote call center working on agents’ satisfaction compared to onsite workers. A cross-section study was conducted between December 2020 and April 2021 that include 124 agents working in a governmental medical call center in Saudi Arabia. Each agent was receiving a questionnaire that investigates his/her satisfaction with the job nature, supervisor support, job autonomy, job productivity, and performance. Seventy-seven physicians working onsite were compared to forty-seven physicians remotely working in the medical call center. The mean age of the physicians included was 43.17 ± 8.4 years, and most of them were male (>70%), married (>85%), and family medicine specialists (>50%). The mean years of experience in the medical field of the physicians included was 16.87 ± 8.07 years, and the mean years of experience in the medical call center was 1.44 ± .97 years. Onsite agents were more satisfied concerning job nature, supervisor support, productivity, and performance compared to remote agents (70.82 vs 53.47%, 63.38 vs 55.05%, and 66.51 vs 56.03%, respectively). However, onsite agents were less satisfied regarding job autonomy than remote physicians (46.81 vs 53.19%, P-value = .128). Overall, general satisfaction was more seen in physicians working onsite as opposed to remote workers in the medical call center in Saudi Arabia (64.90 vs 54.25%, P-value < .01).

Published: November 2021

Purpose This study intends to add to previous reports on acute corneal graft rejection following anti-severe acute respiratory syndrome-coronavirus-2 vaccination, providing data to corroborate a possible causative relationship between anti-COVID-19 immunization and corneal graft rejection, regardless of vaccine or graft type. Methods and Results This report describes 4 cases of acute-onset rejection as early as 5 days following the first dose of anti-severe acute respiratory syndrome-coronavirus-2 vaccine types not yet referred for corneal allograft. Patients were individually given the Moderna messenger RNA-1273 COVID-19 vaccine (2 patients) and the AstraZeneca COVID-19 vaccine, Vaxzevria, AZD1222 (2 patients). Conclusions Even though a direct causative effect is hard to prove, temporal proximity between anti-severe acute respiratory syndrome-coronavirus-2 vaccines of different types and consecutive reports of corneal graft rejection indicates the need for further investigation. Consistent advice must be given to corneal transplant patients regarding such risk.
Deceptive behaviour in autism: A scoping review
Authors: Bagnall Ralph , Russell Ailsa , Brosnan Mark , Maras Katie 
Published: November 2021

The ability to deceive is a key milestone in social cognitive development for typically developing individuals. In this scoping review, we systematically searched the literature to summarise research on deceptive behaviour in autism and identify gaps in knowledge. Across the 28 studies identified, three main themes were synthesised, with seven subthemes: (1) Deception ability and prevalence (1a) gameplay deception; (1b) naturalistic deception; (2) Psychological correlates of deception (2a) verbal, intellectual and social ability; (2b) theory of mind (ToM) behaviours; (2c) executive function; and (3) Social learning (3a) training; (3b) social contexts. The findings challenge common stereotypes, showing that autistic individuals can and do engage in deception. However, many do so less frequently and less adeptly than typically developing individuals. Emerging evidence also suggests that autistic individuals (without co-occurring intellectual disability) may use compensatory strategies when engaging in deception, and that more skilled deceptive behaviour may arise later in life. Implications and directions for future research are discussed. Lay abstract The ability to deceive others is an important skill that usually develops in early childhood. In this review, we give an overview of studies that have examined deceptive behaviour in autistic children, adolescents and adults. We separated the study findings into three main categories and seven sub-categories: (1) Deception ability and prevalence (1a) gameplay deception; (1b) naturalistic deception; (2) Psychological processes in deception (2a) verbal, intellectual and social ability; (2b) ability to understand others’ thoughts and beliefs; (2c) cognitive ability; and (3) Social learning (3a) training; (3b) social contexts. Contrary to some stereotypes, we found that autistic people can and do deceive but often find this more difficult than non-autistic people. We also found that autistic people may use different psychological processes than non-autistic people when deceiving and may get better at deception in adulthood.

Purpose: The calcium score is a measure of vessel wall calcification and has clinical applications when studied in different vascular beds. The presence of vascular calcification in the arteries of the lower limbs is very common in patients with peripheral arterial disease; however, its relationship with the postoperative outcomes in patients undergoing lower limb revascularization is still poorly studied. The aim of this study is to evaluate association between the calcium score of lower limbs and the postoperative outcomes in patients with peripheral arterial disease undergoing revascularization procedures. Methodology: We retrospectively analyzed 88 lower limb revascularization procedures in 72 patients with critical limb ischemia who had enhanced computed tomography for preoperative evaluation. The calcium score was calculated, from the angiographic phase of preoperative computed tomography, in the segments of the aorta, iliac, femoropopliteal, and infrapopliteal. It was also calculated the calcium score of the operated limb, and the total calcium score using a standardized method. The outcomes evaluated were the occurrence of acute myocardial infarction, amputation, patency, technical success, and death from any cause. Patients were followed up through a 12 month period. Results: Among the 88 procedures performed, 31 (43.1%) lesions were classified as Trans-Atlantic Inter-Society Consensus Document II D. There were 66 (75%) endovascular procedures, 16 (18.2%) open surgery, and 6 (6.8%) hybrid interventions. No statistically significant relationship was found between the calcium score of the segments (aorta, iliac, femoropopliteal, infrapopliteal, the operated limb, and total calcium score) and the outcomes of acute myocardial infarction, amputation, patency, and technical success in any of the periods analyzed. The calcium score of the operated limb was higher in patients who died within 30 days and 6 months (6571 vs 2590.6; p=0.026) and (5227.8 vs 2335.3; p=0.036). Conclusion: A standardized calcium score calculation method with the angiographic phase of the computed tomography is feasible and reproducible. Higher values of the calcifications of the operated limb are related to a greater chance of death in the postoperative period. The calcium score of the operated limb can be considered as a marker of clinical severity and prognosis in this group of patients

Published: November 2021

Selenium is a fundamental trace element of the living system. Microorganisms play a crucial role in the selenium cycle, both in the environment and in life. Biogenic selenium nanoparticles have shown promising prospects for use in medicine as an antioxidant and anticancer agent. In this study, SeNPs were biosynthesized by Penicillium citrinum. The spore suspension which was previously prepared was exposed to different doses of gamma radiation (10, 20, 30, 50, and 60 Gy). SeNPs were then produced by an irradiated P citrinum. UV spectroscopy, transmission electron microscopy, X-ray diffraction, and GSH content were assayed to evaluate the probability of P citrinum synthesizing SeNPs. In conclusion, irradiation of P citrinum by gamma ray enhances the mycosynthesis of SeNPs.
Lessons learnt from transitioning to online mentoring and learning at university during COVID-19 for adults with intellectual disability
Authors: Gobec Charlotte , Turnbull Matthew , Rillotta Fiona 
Published: November 2021

Background: COVID-19 influenced education delivery worldwide. The Up the Hill Project (UTHP), a university mentoring program in Australia for people with intellectual disability, transitioned from a face-to-face to online format during 2020. Results: The experience of transitioning online for one semester (12-week period) had positives and challenges associated with it. The UTHP Coordinator reported initial doubts for the online mode and identified the importance of at home support. However, the experience has opened up avenues for future program practices, such as intake processes and increased flexibility. From the participants’ perspective, the online experience supported participants to develop new technology skills. However, challenges were that participants needed support, and missed face-to-face contact. Conclusion: Online mentoring in the UTHP had challenges, but has also supported continuation of university programs. Lessons learnt will influence the development of the UTHP in some capacity into the future.

Published: November 2021

Background: Ovarian cancer (OvCa) constitutes a rare and highly aggressive malignancy and is one of the most lethal of all gynaecologic neoplasms. Due to chemotherapy resistance and treatment limitations because of side effects, OvCa is still not sufficiently treatable. Hence, new drugs for OvCa therapy such as P8-D6 with promising antitumour properties have a high clinical need. The benzo[ c]phenanthridine P8-D6 is an effective inductor of apoptosis by acting as a dual topoisomerase I/II inhibitor. Methods: In the present study, the effectiveness of P8-D6 on OvCa was investigated in vitro. In various OvCa cell lines and ex vivo primary cells, the apoptosis induction compared with standard therapeutic agents was determined in two-dimensional monolayers. Expanded by three-dimensional and co-culture, the P8-D6 treated cells were examined for changes in cytotoxicity, apoptosis rate and membrane integrity via scanning electron microscopy (SEM). Likewise, the effects of P8-D6 on non-cancer human ovarian surface epithelial cells and primary human hepatocytes were determined. Results: This study shows a significant P8-D6-induced increase in apoptosis and cytotoxicity in OvCa cells which surpasses the efficacy of well-established drugs like cisplatin or the topoisomerase inhibitors etoposide and topotecan. Non-cancer cells were affected only slightly by P8-D6. Moreover, no hepatotoxic effect in in vitro studies was detected. Conclusion: P8-D6 is a strong and rapid inductor of apoptosis and might be a novel treatment option for OvCa therapy.

Published: November 2021

Background Chronic rhinosinusitis (CRS) describes a heterogenous group of diseases including CRS with (CRSwNP) or without nasal polyps (CRSsNP), aspirin-exacerbated respiratory disease (AERD), and allergic fungal rhinosinusitis (AFRS). It affects 10 to 15% of the US population and is more common in women and White patients. However, these estimates are based on survey and database studies with innate diagnostic inaccuracy. Additionally, few studies report subtype-specific demographics. We explore the demographic differences of CRS in the U.S. by subtype and region. Objective To characterize demographic differences between the CRS population and the overall US population, and also between different CRS subtype populations. Methods We performed a systematic review for articles reporting on US demographics of adults with CRS. Study participants were required to have been diagnosed using consensus criteria. Data on demographics, geographic region, and CRS subtype were analyzed. Results Our study analyzed 31 unique studies representing 8409 patients with 50.7% females and weighted mean age of 48.0 years. Compared to the overall US population, CRS patients were predominantly White (78.5%) and non-Hispanic (94.5%) with under-representation of other races. Grouped by subtype, CRSwNP affected a significantly higher proportion of men (59.8%). AFRS affected a significantly higher proportion of Black patients (53.8%) while CRSsNP was more prevalent in White patients (84.2%). When grouped by region, the South had a significantly higher proportion of female (53%) and Black (17.8%) CRS patients. The West had a significantly higher proportion of Asian (4.5%) and Hispanic (12.3%) patients. Conclusions Significant demographic differences exist in CRS patients based on subtype and region. These data provide an estimation of the demographic make-up of CRS, but further high-level demographic studies are needed.

Abstract
Background
The purpose of this study was to evaluate the clinical and radiographic outcomes after medial patellofemoral ligament (MPFL) reconstruction combined with supracondylar biplanar femoral derotation osteotomy (FDO) in recurrent patellar dislocation (RPD) with increased femoral anteversion angle (FAA) and genu valgum.

Methods
Between January 2017 to December 2020, a total of 13 consecutive patients (13 knees, 4 males and 9 females, mean age 18.7 (range, 15–29 years) with RPD with increased FAA (FAA > 25°) and genu valgum (mechanical axis deformity of ≥5°) who underwent supracondylar biplanar FDO using a Tomofix-locking plate combined with MPFL reconstruction in our institution were included. Preoperative full-leg standing radiographs, lateral views, and hip-knee-ankle computed tomography (CT) scans were used to evaluate the mechanical lateral distal femoral angle (mLDFA), anatomical femorotibial angle (aFTA), mechanical axis, patellar height, tibial tubercle-trochlear groove (TT-TG) distance, and torsional angle of the tibial and femoral in the axial plane. Patient reported outcomes were evaluated using the International Knee Documentation Committee (IKDC) score, Kujala score, Lysholm score, visual analog scale (VAS), and Tegner score preoperatively and postoperatively. Postoperative CT scans were used to evaluate the changes of FAA and TT-TG, and full-leg standing radiographs was used to evaluate the changes of mLDFA, aFTA, and mechanical axis.

Results
A total of 13 patients (13 knees) were included with an average follow-up period of 26.7 months (range 24–33). No cases developed wound infection, soft tissue irritation, and recurrent patellar dislocation during the follow-up period after surgery. Bone healing at the osteotomy site was achieved in all cases, and all patients regained full extension and flexion. Clinical outcomes (VAS, Kujala, IKDC, Lysholom, and Tegner scores) improved significantly at the final follow-up after surgery (p < 0.05). The mean mLDFA, aFTA, mechanical axis, and TT-TG distance showed statistically significant improvement following the combined surgery (p < 0.05), while the CDI did not change significantly after surgery (p>0.05).

Conclusion
MPFL reconstruction combined with supracondylar biplanar FDO showed satisfactory clinical outcomes and radiographic results in the short-term follow-up period.

Abstract
Background
Little is known about the effectiveness of surface cooling (SC) and endovascular cooling (EC) on the outcome of out-of-hospital cardiac arrest (OHCA) patients receiving target temperature management (TTM) according to their initial rhythm.

Methods
We retrospectively analysed data from the Japanese Association for Acute Medicine Out‐of‐Hospital Cardiac Arrest registry, a multicentre, prospective nationwide database in Japan. For our analysis, OHCA patients aged ≥ 18 years who were treated with TTM between June 2014 and December 2017 were included. The primary outcome was 30-day survival with favourable neurological outcome defined as a Glasgow–Pittsburgh cerebral performance category score of 1 or 2. Cooling methods were divided into the following groups: SC (ice packs, fans, air blankets, and surface gel pads) and EC (endovascular catheters and any dialysis technique). We investigated the efficacy of the two categories of cooling methods in two different patient groups divided according to their initially documented rhythm at the scene (shockable or non-shockable) using multivariable logistic regression analysis and propensity score analysis with inverse probability weighting (IPW).

Results
In the final analysis, 1082 patients were included. Of these, 513 (47.4%) had an initial shockable rhythm and 569 (52.6%) had an initial non-shockable rhythm. The proportion of patients with favourable neurological outcomes in SC and EC was 59.9% vs. 58.3% (264/441 vs. 42/72), and 11.8% (58/490) vs. 21.5% (17/79) in the initial shockable patients and the initial non-shockable patients, respectively. In the multivariable logistic regression analysis, differences between the two cooling methods were not observed among the initial shockable patients (adjusted odd ratio [AOR] 1.51, 95% CI 0.76–3.03), while EC was associated with better neurological outcome among the initial non-shockable patients (AOR 2.21, 95% CI 1.19–4.11). This association was constant in propensity score analysis with IPW (OR 1.40, 95% CI 0.83–2.36; OR 1.87, 95% CI 1.01–3.47 among the initial shockable and non-shockable patients, respectively).

Conclusion
We suggested that the use of EC was associated with better neurological outcomes in OHCA patients with initial non-shockable rhythm, but not in those with initial shockable rhythm. A TTM implementation strategy based on initial rhythm may be important.
