Clinical analysis of liver dysfunction in pregnant patients with mild SARS CoV-2 infection

Objective: The current study aimed to describe the clinical characteristics of mild SARS-CoV-2 infected pregnant women with abnormal liver function (ALF), explore the association between ALF with maternal and fetal outcomes. Method(s): This retrospective analysis included 87 pregnant patients with mild SARS-CoV-2 infection admitted and treated from December 1, 2022, to 31, 2022 in the department of Obestircs at Beijing Obstetrics and Gynecology Hospital. We evaluated patients for demographic and clinical features, laboratory parameters and pregnancy complications. Result(s): 27 Patients in this cohort had clinical presentations of ALF. Compared with the control group, the peripheral blood platelet (PLT), D-dimer quantitative determination (D-Dimer), lactate dehydrogenase (LDH), total protein (TP), albumin (ALB), indirect bilirubin (DBIL), gamma- glutamyltranspeptidase (GGT) and total bile acid (TBA) showed significantly differences (p<0.05). 12 cases (44.44%) complicated with pregnancy induced hypertension (PIH), 14 cases (51.85%) complicated with intrahepatic cholestasis of pregnancy (ICP), 2 cases (7.4%) complicated with acute fatty liver during pregnancy (AFLP) and 5 cases (14.81%) complicated with postpartum hemorrhage in patients with abnormal LFT were significantly higher than those in the control group (p<0.05). Compared with the control group, the incidence of premature delivery (22.22%) and fetal distress (37.04%) in the experiment group were significantly higher (p<0.05), and the incidence of neonatal asphyxia was not significantly different (p>0.05). Conclusion(s): Pregnant women are generally susceptible to mild SARS-CoV-2 and may induce ALF. ALF is associated with increased risk of mother and infant. The maternal and infant outcomes of those who terminated pregnancy in time are acceptable. Therefore, pregnant women with COVID-19 who received antiviral treatment should be closely monitored for evaluating liver function and relevant indicators. The long-term outcomes in the future are worth to further study.Copyright © 2023

Biodegradable Polyester Nanoparticle Vaccines Deliver Self-Amplifying mRNA in Mice at Low Doses

Delivery of self-amplifying mRNA (SAM) has high potential for infectious disease vaccination due to its self-adjuvanting and dose-sparing properties. Yet a challenge is the susceptibility of SAM to degradation and the need for SAM to reach the cytosol fully intact to enable self-amplification. Lipid nanoparticles are successfully deployed at incredible speed for mRNA vaccination, but aspects such as cold storage, manufacturing, efficiency of delivery, and the therapeutic window can benefit from further improvement. To investigate alternatives to lipid nanoparticles, a class of >200 biodegradable end-capped lipophilic poly(beta-amino ester)s (PBAEs) that enable efficient delivery of SAM in vitro and in vivo as assessed by measuring expression of SAM encoding reporter proteins is developed. The ability of these polymers to deliver SAM intramuscularly in mice is evaluated, and a polymer-based formulation that yields up to 37-fold higher intramuscular (IM) expression of SAM compared to injected naked SAM is identified. Using the same nanoparticle formulation to deliver a SAM encoding rabies virus glycoprotein, the vaccine elicits superior immunogenicity compared to naked SAM delivery, leading to seroconversion in mice at low RNA injection doses. These biodegradable nanomaterials may be useful in the development of next-generation RNA vaccines for infectious diseases.Copyright © 2023 The Authors.

Evaluating real world clinical response of once weekly subcutaneous semaglutide and its daily oral formulation for the treatment of type 2 diabetes in primary care practice

Objective: Semaglutide is the first glucagon-like peptide- 1 receptor agonist with oral and subcutaneous formulations. We studied patient adherence and clinical response following their prescription in a primary care setting. Method(s): We searched for patients starting semaglutide between October 2020 to November 2021 in primary care registries in Dudley, West Midlands. We tracked their collection of medications for up to six months, changes in HbA1C and weight if these data were available at 26 weeks (range 22-52 weeks), with significance tested using a t-test. Patients prescribed both formulations were excluded. Result(s): Clinical data were available in 180 of the 443 patients. Baseline HbA1c was 79.0 +/- 18.6mmol/mol (Ozempic) and 81.9 +/- 19.3mmol/mol (Rybelsus) and pre-treatment weight was 108.4 +/- 10.5 kg (Ozempic) and 104.3 +/- 26.7 kg (Rybelsus). 62.8% of patients were of non-white ethnicity and 82.8% were on >= two anti-diabetic drugs. In patients with six-month follow-up data, mean reduction in HbA1c and weight was 17.1 +/- 20.8mmol/ mol and 3.9 +/- 6.2 kg (Ozempic n = 53, p < 0.01) and 18.2 +/- 14.5mmol/mol and 5.9 +/- 4.2 kg (Rybelsus n = 5, p < 0.05). Drug continuation rates were measured in 324 patients. 3.2% and 19.0% of patients for Ozempic and Rybelsus respectively did not obtain further prescriptions after their initial script. At six months, 87.2% continued with Ozempic and 57.2% with Rybelsus. Conclusion(s): This study demonstrates similarly significant reductions in HbA1c and weight with Ozempic and Rybelsus, despite the complexity of follow-up during Covid-19 restrictions. The lower adherence to Rybelsus warrants further study.

Whats' happening on the follicular unit of adolescents after the COVID-19 pandemic: Severe acne is a growing problem of nowadays

Objectives: Acne is a leading skin problem in adolescents. After the end of COVID-19 pandemic, with the gradual transition to the routine life, we started to encounter more severe forms of acne in the last 6-month than we had seen before in the 10 year period of our Paediatric Dermatology outpatient clinic. Method(s): We evaluated the demographic and clinical characteristics, COVID infection and vaccination status, and treatment of patients who were treated at our Paediatric Dermatology outpatient clinic in the last 6 months due to severe acne. Result(s): One of our patients had acne fulminans, and four patients had acne conglobata. The common features of these patients presenting with severe acne were that they were young boys aged 15- 16 years, medium height, normal weight, and skin type 3-4. All patients had a family history of acne in their parents. They had no known comorbidities, additional treatment, history of nutritional supplement use, or accompanying arthralgia or arthritis. Four patients were initially treated with isotretinoin for severe acne, developed acne conglobata, and one developed acne fulminans during the follow-up period. Dapsone therapy was initiated in all patients according to the severity of the lesions, and adalimumab was administered to acne fulminans. Discussion(s): The frequent occurrence of severe forms of acne after the pandemic raises the question of whether COVID-19 infection or vaccination may play a role in its aetiology. Cases of mask-related acne exacerbation during COVID-19 have been well-described in the literature. However, there are no data on the effects of COVID-19 vaccination or infection on the development of severe acne. In this report, we present cases of adolescent patients with severe acne to investigate the possible reasons for the increasing number of severe acne cases presenting to our outpatient clinic during the postpandemic period.

Persistent chemosensory dysfunction in COVID-19 patients: a deep dive into the psychophysical and genetic characterisation of an Italian cohort

Background/Objectives: Chemosensory dysfunction is a hallmark of SARS-CoV-2 infection;nevertheless, the genetic factors predisposing to long-term smell and taste loss are still unknown. This study aims to identify candidate genes possibly involved in persistent smell/taste loss through Whole Genome Sequencing (WGS) analysis of a large cohort of 130 fully characterised Italian individuals, previously diagnosed with COVID-19. Method(s): DNA of all analysed patients was used to perform WGS analysis, and a detailed personal anamnesis was collected. Moreover, orthonasal function was assessed through the extended Sniffin' Sticks test, retronasal function was tested with 20 powdered tasteless aromas, and taste was determined with validated Taste Strips. Self-reported smell and taste alterations were assessed via Visual Analog Scales plus questionnaires. Result(s): The clinical evaluation allowed to classify the patients in two groups: 88 cases affected by persistent smell dysfunction (median age, 49) and 42 controls (median age, 51). Among cases, 26.1% (n = 23) were functionally anosmic and 73.9% (n = 65) were hyposmic. Within cases, 77 underwent the taste strip test: 53.2% (n = 41) presented hypogeusia and 46.8% (n = 36) were normogeusic. Preliminary WGS results on a first subset of 76 samples confirmed the important role of UGT2A1 gene, previously described as involved in smell loss. Interestingly, we identified a nonsense variant (rs111696697, MAF 0.046) significantly associated with anosmia in males (p-value: 0.0183). Conclusion(s): Here, for the first time a large cohort of patients, fully characterised through a comprehensive psychophysical evaluation of smell and taste, have been analysed to better define the genetic bases of COVID-19-related persistent chemosensory dysfunction.

Glucosaminylmuramyl dipeptide efficacy in post-COVID-19 patient rehabilitation treatment.

The COVID-19 pandemic has altered people's lifestyles around the world. Prevention of recurrent episodes of the disease and mitigation of its consequences are especially associated with effective post-COVID-19 rehabilitation in patients. The aim of the study was to evaluate the effects of the drug Likopid (glucosaminylmuramyl dipeptide, GMDP) for post-COVID-19 rehabilitation in patients. Material and methods. Patients who recovered from mild to moderate COVID-19 (n=60, mean age 54+/- 11.7 years) were randomized into the observation group (n=30, 15 men and 15 women) who received 2 courses of Licopid (1 mg twice a day) and the comparison group (n=30, 15 men and 15 women). Analysis of the phenotypic and functional characteristics of the innate immune cellular factors was carried out before the start of immunomodulatory therapy, immediately after the end of the course, and also after 6 months observations. In order to assess the quality of life of all patients, we used the SF-36 Health Status Survey and the Hospital Anxiety and Depression Scale questionnaires. Results. During assessing the effect of immunomodulatory therapy on the parameters of innate immunity of patients at the stage of rehabilitation after COVID-19, an increase in the protective cytolytic activity of CD16+ and CD8+Gr+ cells, as well as a persistent increase in TLR2, TLR4 and TLR9 expression was found, which indicates the antigen recognition recovery and presentation at the level of the monocytic link of the immune system. The use of GMDP as an immunomodulatory agent resulted in an 8-fold reduction in the frequency and severity of respiratory infections due to an increase in the total monocyte count. As a result of assessing patients' quality of life against the background of the therapy, a positive dynamic in role functioning was revealed in patients. In the general assessment of their health status, an increase in physical and mental well-being was noted during 6 months of observation. The comparison group showed no improvement in the psychoemotional state. Discussion. The study demonstrated the effectiveness of GMDP immunomodulatory therapy in correcting immunological parameters for post-COVID-19 rehabilitation in patients. The data obtained are consistent with the previously discovered ability of GMDP to restore impaired functions of phagocytic cells and induce the expression of their surface activation markers, which in turn contributes to an adequate response to pathogens. Conclusion. The study revealed that the correction of immunological parameters with the use of GMDP in COVID-19 convalescents contributed not only to a decrease in the frequency and severity of respiratory infections, but also to an improvement in the psycho-emotional state of patients, and a decrease in anxiety and depression.Copyright © Eco-Vector, 2023.

Preoperative evaluation and timing of surgery for adult patients after covid-19 infection: Recommendations of peking union medical college hospital (2023).

With the adjustment of China's epidemic prevention and control guidelines regarding coronavirus disease of 2019(COVID-19), the preoperative evaluation and timing of surgery for patients after COVID-19 infection have become the focus of attention for both healthcare workers and patients. Based on the latest study and related clinical experience, Peking Union Medical College Hospital (PUMCH) has therefore compiled this multidisciplinary, evidence-based recommendation for concise, individualized, and practical preoperative evaluation and timing of surgery for patients after COVID-19 infection. The recommendations emphasize patients' COVID-19 infection history, the severity of symptoms, and medical/physiologic recovery status during preoperative evaluation. The determination of appropriate length of time between recovery from COVID-19 and surgery/procedure should take into account of patients' underlying health conditions, the severity of the COVID-19 infection course, and the types of surgery and anesthesia scheduled, to minimize postoperative complications. The recommendations are intended to aid healthcare workers in evaluating these patients, scheduling them for the optimal timing of surgery, and optimizing perioperative management and postoperative recovery.Copyright © 2023, Peking Union Medical College Hospital.

Complications Associated with Catheter Ablation of Atrial Fibrillation in Current Practice: Insights from a Large, Real-World Collaboration

Background: Catheter ablation is a cornerstone treatment for symptomatic atrial fibrillation (AF) with major improvements in safety over time. However, rates of adverse events with use of current techniques in a contemporary quality-focused network remain undefined. Objective(s): Across a large, real-world sample, we sought to describe (1) rates of major, adverse events associated with catheter ablation of AF and (2) patient-level factors associated with complications. Method(s): Utilizing the REAL-AF collaboration, a registry of contemporary AF ablation procedures with granular patient, procedural and follow-up data comprised of cases from over 50 operators across academic and non-academic sites, we evaluated all patients undergoing their first ablation procedure from January 2018 - June 2022. Risk-adjusted analyses were conducted to evaluate the relationship between patient factors and complications. Result(s): Among 3144 patients (age 66.1 +/- 11.0 years, 42% female, 67.1% paroxysmal, 32.9% persistent) who underwent AF ablation, procedure-related complications (n =77) were identified in 65 patients (2.1%) with multiple complications occurring in 9 patients (0.2%). Most complications (n=70, 93.5%) occurred in the peri-procedural (within 30 days) period and 6.5% (n=5) after 30 days, the latter of which all represented vascular injuries (Figure). Major complications (18 of 72 peri-procedural complications, 25.0%) are defined, detailed, and associated data reported in the Figure. Unadjusted (16.0% without CHF vs. 33.3% with CHF, p = 0.045) and risk-adjusted (OR 2.8, 95% CI 1.03-7.60, p=0.045) analyses indicated history of CHF was associated with a composite outcome of major complications. Analyses of independent complications showed those who suffered from peri-procedural stroke (n=3) were of significantly greater age (77.3 +/- 5.5 years vs. 66.1 +/- 10.9 years, p=0.035). Risk-adjusted analyses showed history of vascular disease (OR 2.9, 95% CI 1.02-8.20, p=0.045) was associated with vascular injury (n=18). From 0-695 days post-procedure, 31 deaths occurred (unknown cause: 17, COVID-19 related: 4, heart failure: 2, cardiac arrest: 2). Conclusion(s): Major complications represent rare events among those undergoing AF ablation in current practice. Risk-adjusted analyses suggest a history of CHF is associated with major complications. Similarly, older age and a history of vascular disease are associated with stroke and vascular complications, respectively. [Formula presented]Copyright © 2023

Extracorporeal membrane oxygenation instead of invasive ventilation in patients with COVID-19 acute respiratory distress syndrome (ARDS) and pneumomediastinum: A cohort trial

Objectives: In patients with severe respiratory failure, invasive ventilation may deteriorate the pneumomediastinum and hypoxia. This study aimed to compare the mortality and the complications of the patients with coronavirus disease 2019 (COVID-19) related severe ARDS treated with invasive ventilation or veno-venous ECMO (VV-ECMO) to avoid intubation. We hypothesized that VV-ECMO support without prior intubation is a feasible alternative strategy to invasive ventilation. Method(s): This retrospective study evaluated patients with COVID-19 related severe respiratory failure and radiological evidence of pneumomediastinum. The primary outcome was intensive care unit (ICU) survival at 90 days. Result(s): Out of 347 patients with COVID-19 disease treated in our unit, 22 patients developed spontaneous pneumomediastinum associated with deterioration of respiratory function. In 13 patients (59%), invasive ventilation was chosen as initial respiratory support;in 9 patients (41%), VV-ECMO was chosen as initial respiratory support. The median age of the patients in the invasive ventilation group was 62 years (IQR: 49-69) compared to 53 years (IQR: 46-62) in ECMO group (P=0.31). No statistically significant difference in SAPS II score between the groups was observed (39.7 (IQR: 33.2-45.3) vs. 28.9 (IQR:28.4-34.6), P=0.06). No elevated fluid balance within the first 4 days was observed in the ECMO group compared to the invasive ventilation group (162 mL (IQR: -366-2000) vs. 3905 mL (IQR: 2068-6192), P=0.07). VV-ECMO as the initial strategy for supporting patients with severe respiratory failure and pneumomediastinum, was associated with lower 90 days mortality (HR: 0.33 95%-CI: 0.11-0.97, P= 0.04) compared to patients treated with invasive ventilation (Figure). Conclusion(s): VV-ECMO can be an alternative strategy to invasive ventilation for treating patients with severe respiratory failure and spontaneous pneumomediastinum. (Figure Presented).

Clinical and laboratory characteristics of SARS-CoV-2 infection in overweight and obese patients.

Objective. To assess the impact of obesity and overweight on the course of COVID-19. Patients and methods. This prospective study included 218 patients with SARS-CoV-2 infection aged 18 to 94 years hospitalized between June 2020 and March 2021. We evaluated their clinical and laboratory parameters and their association with body weight. All patients were divided into 3 groups depending on their body mass index (BMI). Group 1 included 81 patients with grade 1-3 obesity (BMI >=30);group 2 comprised 71 overweight patients (BMI >=25 and <30);group 3 included 66 patients with normal body weight (BMI >=18.5 and <25). We analyzed clinical symptoms (including shortness of breath, fever, myalgia, headache, fatigue, changes in the oropharynx, cough, rhinorrhea, sore throat, anosmia, and diarrhea), prevalence of concomitant disorders and complications, findings of computed tomography and pulse oximetry, and findings of instrumental and laboratory examinations (complete blood count, urine test, electrocardiography, echo cardiography, biochemical assays, including C-reactive protein, procalcitonin, alanine aminotransferase, aspartate aminotransferase, lactate, lactate dehydrogenase, activated partial thromboplastin time, prothrombin index, D-dimer, ferritin). Data analysis was performed using the Statistica 6.0 software. Results. We found that overweight and obese patients were more likely to have the main COVID-19 symptoms and comorbidities than those with normal weight. Overweight and obese patients also required respiratory support more frequently than patients with normal weight. Obese and overweight patients had more severe systemic inflammation (CRP, procalcitonin), cytolysis (ALT, AST), and thrombosis (D-dimer). Conclusion. Our findings suggest that obesity and overweight are the factors associated with a more severe SARS-CoV-2 infection, which should be considered when planning their treatment and developing resource strategies.Copyright © 2022, Dynasty Publishing House.

Interpreting High Sensitivity Troponins in Various Acute Clinical Settings - Increased Significance to the Present.Day Cardiologist

High-sensitivity cardiac troponins expedite the evaluation of patients with chest pain in the emergency department. The utility of troponins extends beyond the acute coronary syndromes to accurate the diagnosis of myocardial injury. Troponins are best friends for physicians;however, they are a double-edged sword if not interpreted appropriately. Misdiagnosis is harmful with regard to patient outcomes. The present review focuses on the recent updates in the understanding and interpretation of high-sensitivity troponins in various acute clinical settings. Common mistakes and gray zones in the interpretation of troponins, the concept of myocardial injury versus infarction, newer entities like myocardial infarction (MI) with Nonobstructive Coronary Arteries, recent controversies over the definition of periprocedural MI, complementary role of imaging in the diagnosis of myocardial injury and the role of troponins in the current COVID-19 pandemic are discussed.Copyright © 2022 Saudi Center for Organ Transplantation.

Impact of Universal Masking Precautions during COVID-19 Pandemic on Surgical Site Infection in General Surgery Procedures

Introduction: Increasing evidence demonstrates the effectiveness of universal masking precautions in reducing the transmission of COVID-19. Whether these precautions have an impact on surgical site infections (SSI), currently remains unknown. This study assesses whether implementation of universal masking precautions altered the rates of SSI. Method(s): We performed a single-institution, retrospective cohort study using the NSQIP database, evaluating all patients undergoing most performed general surgery procedures from June 2018 to December 2021. SSI rates were compared between patients who underwent operation before and after implementation of universal masking precautions at our institution in March 2020. Statistical analyses were performed using Fisher's exact test. Result(s): A total of 1,539 patients were included;721 patients were in the pre-masking cohort, while 818 in post-masking cohort. During this time period, a total of 143 (9.3%) patients developed SSI, 3.6% incisional and 5.7% deep organ space infections (OSI) (p=0.6601). Incisional and OSI rates did not differ significantly between the two groups (incisional 3.47% vs 3.67%, p=0.891;OSI 5.41% vs 5.99%, p=0.6608). Sub-analysis of top 5 procedures (by volume - laparoscopic cholecystectomy, hepatectomy, thromboendarterectomy, colectomy with anastomosis, and colectomy with ileocolostomy) demonstrated a significant decrease in incisional infections (3.7% vs 1.62%, p=0.0354). Conclusion(s): While the incidence of SSI did not differ significantly in the overall cohort after implementation of universal masking precautions, there was a decrease in incisional infections in commonly performed procedures at our institution. Future research is needed to identify whether continued masking precautions may minimize the risk of SSI in specific patient populations.

Critical points in randomized research on DCD donor in-situ perfusion (NRP): the interim DONARE Study clinical evaluation

Background/aims: Controlled DCD organ donation (cDCD) is a strategic target for the Italian transplantation network. Italian peculiarities in cDCD donation make published results questionable and raise concern over organ ischemic damage. Consequently, normothermic regional perfusion (NRP) has been strongly recommended in potential cDCD donors. In 2019 the randomized multicenter DONARE study was designed to describe ischemic-reperfusion and inflammatory biomarkers during NRP and to test the potential benefit of apheresis by an adsorbent filter (CytoSorb) included in the NRP circuit. The aim of this report is to describe the modulation of the clinical characteristics and of the NRP in the DONARE study enrolled cases. Method(s): The study protocol was defined by the DCD national working group and proposed to all the Italian DCD donation centers. The coordinating center (CNT) has monitored the evolving cDCD activity to preserve the study capacity of representing the Italian scenario. Samples have been blindly centralized to an independent laboratory for cytokines profiling. The outcomes of transplanted organs have been recorded in the national quality database. Result(s): From September 2020 to June 2022, 27 out of the 40 planned cases have been enrolled in six centers: 4 in 2020, 12 in 2021 and 11 within June 2022. Approval is still pending in other centers. Main causes of exclusion among potential cDCD donors were: age above 65 (in 2020), e-CPR prior- to-death, shortage in personnel and COVID-19 restrictions. The age limit for enrolment (<65yrs) was abolished by amendment due to the national trend: mean age of enrolled cases increased from 57+/-6 in 2020 to 67+/-6 years in 2022. Mean NRP duration decreased from 223,3+/-39,2 in 2020 to 168,9+/-42,6 minutes in 2022;serial samples (4/2 with/without Cytosorb, from T0 to T4) from different points of the NRP circuit have been completed throughout the procedure in all the cases. All the enrolled cases became utilized donors. No study-related adverse event has been reported. Conclusion(s): Coordination of multicenter studies in the rapidly evolving scenario of controlled DCD donation should take advantage of continuous monitoring of real-life procedures and auditing of adherence to operational recommendations. The interim evaluation confirms the feasibility and safety of the study.

Allergic reactions of COVID-19 vaccine based on mRNA-LNP and its pharmacokinetics in vivo.

Vaccination has been proved to be the most effective strategy to prevent the Corona Virus Disease 2019 (COVID-19). The mRNA vaccine based on nano drug delivery system (NDDS) - lipid nanoparticles (LNP) has been widely used because of its high effectiveness and safety. Although there have been reports of severe allergic reactions caused by mRNA-LNP vaccines, the mechanism and components of anaphylaxis have not been completely clarified yet. This review focuses on two mRNA-LNP vaccines, BNT162b2 and mRNA-1273. After summarizing the structural characteristics, potential allergens, possible allergic reaction mechanism, and pharmacokinetics of mRNA and LNP in vivo, this article then reviews the evaluation methods for patients with allergic history, as well as the regulations of different countries and regions on people who should not be vaccinated, in order to promote more safe injection of vaccines. LNP has become a recognized highly customizable nucleic acid delivery vector, which not only shows its value in mRNA vaccines, but also has great potential in treating rare diseases, cancers and other broad fields in the future. At the moment when mRNA-LNP vaccines open a new era of nano medicine, it is expected to provide some inspiration for safety research in the process of research, development and evaluation of more nano delivery drugs, and promote more nano drugs successfully to market.Copyright © 2023, Chinese Pharmaceutical Association.

The teaching strategic effectiveness of problem-based learning assisted (PBL) with objective structured clinical examination (OSCE) on therapeutic nutrition course.

This purpose of this study is to help students developing problem-solving skills by using Problem-based Learning (PBL) as a teaching model, combining with the Objective Structured Clinical Examination (OSCE) as a training tool to evaluate students' clinical competencies. Sixty-five college junior students from a therapeutic nutrition course were participated. The topics of PBL included diabetes, kidney disease, cancer, and cardiovascular disease. For each disease, pre- and post-test quiz and after class exam were assessed to evaluate the students' learning effectiveness. Due to the impact of the COVID-19 epidemic, OSCE was performed online. The focus group interview and learning effectiveness questionnaire were conducted by the end of this course for all participants. Moreover, 37 students who attended the dietitian internship filled in the learning effectiveness questionnaire again after the internship. The results indicated that after the PBL, the post quiz score for each disease was increased, and through the online OSCE training, students' abilities to master nutrition education and counseling had been upgraded. Students indicated that both PBL and OSCE training could contributed to the learning effectiveness. The better academic performance students were, the more willing they are to work in nutrition-related fields in the future. For those who finished the dietitian internship agreed that they could understand the work content better in general regional and regional hospitals than in teaching ones. In conclusion, PBL teaching model combined with OSCE training could effectively improve students' learning motivation, learning effectiveness and practical application in a therapeutic nutrition course.Copyright © 2022 Nutrition Society in Taipei.

An EPPIC tale - 30 years of EPPIC and PACE

Background: The Early Psychosis Prevention and Intervention Centre (EPPIC) and the Personal Assessment and Crisis Evaluation (PACE) were established in Melbourne in 1992. The two services focused on the early detection of emerging illnesses and the development of clinical interventions for psychosis in young people. Aim(s): To describe the development and evolution of the EPPIC and PACE teams over the past 30 years. Method(s): Initially a modest service, operating on one site with fewer than 100 new clients each year, the service has expanded to nine subteams across two regional hubs and three satellite clinics. We will describe the components of the services and the changes to service provision over a 30-year period. Result(s): Over the past 30 years, national and international early psychosis services have developed and youth services have broadened their scope. Service models are being developed that reflect a staged model of illness and clinical care to ensure interventions are responsive to young people's needs. We will outline some of the challenges for EPPIC and PACE in delivering evidence-based interventions across a large service with limited clinical resources, as well as through multiple Covid lockdowns. One of the ongoing challenges is to maintain a focus on early intervention of positive symptoms of psychosis amongst increasing diagnostic complexity and associated interventions. Conclusion(s): The EPPIC and PACE clinical model has been successfully replicated in a number of services around Australia and worldwide. Challenges and future directions will be discussed further.

Animal Pre-Clinical Study of an Inactivated SARS-CoV-2 Vaccine candidate (Osvid-19 ): Immunogenicity, Protective, and Safety Aspects

Background: This study aimed to evaluate the outcomes of preclinical studies on the safety and immunogenicity of an inactivated COVID-19 vaccine candidate to warrant further clinical evaluation. Method(s): SARS-CoV-2 positive nasopharyngeal swab specimens were confirmed by real-time polymerase chain reaction and next-generation sequencing. The safety and immunogenicity tests of the COVID-19 vaccine were carried out in rats and Rhesus monkeys, and Balb/C mice and Rhesus monkeys, respectively. Result(s): The candidate vaccine was well tolerated and induced promising levels of SARS-CoV-2- specific IgG1, IgG2a, and Granzyme B in Balb/C mice, and anti-SARS-CoV-2 spike IgG and neutralizing antibodies in Rhesus monkeys. Based on cVNT results, the inactivated vaccine in 0.5 and 1 microg/100 microL doses was able to induce a neutralizing effect against the SARS-CoV-2 virus up to a dilution of 1:512 and 1:1000. The protective efficacy of the vaccine candidate was challenged with 2 x108 PFU of live viruses and confirmed by lung CT scan and histopathological evaluations compared to the control group. Repeated intramuscular injection of the candidate vaccine was generally well-tolerated in Rats and Rhesuses. No significant side effects were observed in rats injected with ten full human doses and in the Rhesus monkeys with three full human doses. Conclusion(s): Based on the findings presented in this study, it is recommended that this vaccine be moved into human testing commencing with a phase I clinical trial.Copyright © 2021 Muslim OT et al.

An investigation of radiation therapy peer group supervision in a metropolitan cancer centre

Objectives: To investigate radiation therapists' perceptions of participating in peer group supervision (PGS) and the effects of the COVID-19 pandemic on PGS. Method(s): Radiation therapists were introduced to PGS at an in-service facilitated by an employee assistance program representative. Nine volunteers were then placed into one of two PGS groups of similar experience levels. Groups met monthly for PGS sessions;and after six and 12 meetings each participant was sent a link to the 14-item Clinical Supervision Evaluation Questionnaire (CSEQ),1 three open-ended and three demographic questions. The study used both quantitative and qualitative methods. Result(s): Survey completion rates were 8/9 (88.9%) pre- and 6/7 (85.7%) post-COVID-19. Analysis of the CSEQ revealed that pre-COVID-19 seven participants (87.5%) and post-COVID-19 five participants (71.4%) had a positive experience with PGS. One (12.5%) and two (28.6%) participants pre- and post-COVID-19, respectively, stated that their experience was neither positive nor negative. The thematic data showed that the participants perceived PGS to assist with (i) feeling supported at work, (ii) developing an element of trust between group members, (iii) encouraging self-reflection, (iv) fostering an awareness of others, and (v) increasing problem-solving skills. Restrictions due to the COVID-19 pandemic led to fewer regular meetings, which had a negative impact on participants. Conclusion(s): Involvement in PGS within a radiation therapist setting has reportedly positively affected those involved. Regular access to a supportive, trusting team has enabled the participants to self-reflect and better troubleshoot work-related experiences.
