Abstract
Chelating ligands have had a tremendous impact in coordination chemistry and catalysis. Notwithstanding their success as strongly σ-donating and π-accepting ligands, to date no chelating bis[cyclic (alkyl)(amino)carbenes] have been reported. Herein, we describe a chelating, C2-symmetric bis[cyclic (alkyl)(amino)carbene] ligand, which was isolated as a racemic mixture. The isolation and structural characterization of its isostructural, pseudotetrahedral complexes with iron, cobalt, nickel, and zinc dihalides featuring eight-membered metallacycles demonstrates the binding ability of the bis(carbene). Reduction of the nickel(II) dibromide with potassium graphite produces a dicoordinate nickel(0) complex that features one of the narrowest angles measured in any unsupported dicoordinate transition metal complexes.

Abstract
BACKGROUND The Coronavirus Disease 2019 (COVID-19) pandemic led to extensive vaccination campaigns worldwide, including in Australia. Immunity waning and the emergence of new viral variants pose challenges to the effectiveness of vaccines. Our study aimed to assess the relative effectiveness (rVE) of 3 and 4 compared with 2 doses of COVID-19 vaccine. The study focuses on the Victorian population, a majority of whom had no prior exposure to the virus before vaccination. METHODS We used routinely collected data for the state of Victoria, Australia, to assess rVE during an Omicron-dominant period, 1 June 2022 to 1 March 2023. Immunisation, notifications, hospitalisations and mortality data for residents aged 65 years and older were linked for analysis. Cox proportional hazard regression was used to estimate the rVE against COVID-19 hospitalisation or death, accounting for key confounders with vaccination as a time-varying covariate. RESULTS In 1,070,113 people 65 years or older who had received their second dose, a third and fourth dose of a COVID-19 vaccine significantly reduced the hazard of hospitalisation or death compared to two doses. rVE was highest within two weeks from administration at 40 % (95 % CI: 0 % to 64 %) and 66 % (95 % CI: 60 % to 71 %) for a third and fourth dose, respectively. Additional protection conferred by third and fourth doses waned over time from administration. CONCLUSIONS Our findings underscore the need for additional vaccine doses and updated vaccine strategies. These findings have implications for public health advice and COVID-19 vaccine strategies. Further research and monitoring of vaccine effectiveness in real-world settings are warranted to inform ongoing pandemic response efforts.

Abstract
Background Oral Antiviral (OAV) COVID-19 treatments are widely used, but evidence for their effectiveness against the Omicron variant in higher risk, vaccinated individuals is limited. Methods Retrospective study of two vaccinated cohorts of COVID-19 cases aged ≥70 years diagnosed during a BA.4/5 Omicron wave in Victoria, Australia. Cases received either nirmatrelvir-ritonavir or molnupiravir as their only treatment. Data linkage and logistic regression modelling was used to evaluate the association between treatment and death and hospitalisation and compared with no treatment. Findings Of 38,933 individuals in the mortality study population, 13.5% (n = 5250) received nirmatrelvir-ritonavir, 51.3% (n = 19,962) received molnupiravir and 35.2% (n = 13,721) were untreated. Treatment was associated with a 57% (OR = 0.43, 95% CI 0.36-0.51) reduction in the odds of death, 73% (OR = 0.27, 95% CI 0.17-0.40) for nirmatrelvir-ritonavir and 55% (OR = 0.45, 95% CI 0.38-0.54) for molnupiravir. Treatment was associated with a 31% (OR = 0.69, 95% CI 0.55-0.86) reduction in the odds of hospitalisation, 40% (OR = 0.60, 95% CI 0.43-0.83) for nirmatrelvir-ritonavir and 29% (OR = 0.71, 95% CI 0.58-0.87) for molnupiravir. Cases treated within 1 day of diagnosis had a 61% reduction in the odds of death (OR = 0.39, 95% CI 0.33-0.46) compared with 33% reduction for a delay of 4 or more days (OR = 0.67, 95% CI 0.44-0.97). Interpretation Treatment with both nirmatrelvir-ritonavir or molnupiravir was associated with a reduction in death and hospitalisation in vaccinated ≥70 years individuals during the Omicron era. Timely, equitable treatment with OAVs is an important tool in the fight against COVID-19. Funding There was no funding for this study.

Abstract
AIMS To describe the process and outputs of a workshop convened to identify key priorities for future research in the area of diabetes and physical activity and provide recommendations to researchers and research funders on how best to address them. METHODS A 1-day research workshop was conducted, bringing together researchers, people living with diabetes, healthcare professionals, and members of staff from Diabetes UK to identify and prioritise recommendations for future research into physical activity and diabetes. RESULTS Workshop attendees prioritised four key themes for further research: (i) better understanding of the physiology of exercise in all groups of people: in particular, what patient metabolic characteristics influence or predict the physiological response to physical activity, and the potential role of physical activity in beta cell preservation; (ii) designing physical activity interventions for maximum impact; (iii) promoting sustained physical activity across the life course; (iv) designing physical activity studies for groups with multiple long-term conditions. CONCLUSIONS This paper outlines recommendations to address the current gaps in knowledge related to diabetes and physical activity and calls on the research community to develop applications in these areas and funders to consider how to stimulate research in these areas.

Abstract
The objective of this work was to evaluate the inter-rater and intra-rater reliability and minimal detectable difference (MDD) of pressure pain thresholds (PPTs) in pain-free participants with two examiners over two consecutive days in a cross-sectional study design. Examiners used a standardized method to measure and locate a specific testing site over tibialis anterior for PPT testing with a hand-held algometer. The mean of each examiner's three PPT measurements was used to calculate the intraclass correlation coefficient, inter-rater reliability, and intra-rater reliability. The minimal detectable difference (MDD) was calculated. Eighteen participants were recruited (11 female). The inter-rater reliability was 0.94 and 0.96 on day 1 and day 2, respectively. Intra-rater reliability for the examiners was 0.96 and 0.92 on day 1 and day 2, respectively. The MDD on day 1 was 1.24 kg/cm2 (CI: 0.76-2.03) and the MDD on day 2 was 0.88 kg/cm2 (CI: 0.54-1.43). This study demonstrates high inter- and intra-rater reliability and the MDD values for this method of pressure algometry.

Abstract
BACKGROUND Policy responses to COVID-19 in Victoria, Australia over 2020-2021 have been supported by evidence generated through mathematical modelling. This study describes the design, key findings, and process for policy translation of a series of modelling studies conducted for the Victorian Department of Health COVID-19 response team during this period. METHODS An agent-based model, Covasim, was used to simulate the impact of policy interventions on COVID-19 outbreaks and epidemic waves. The model was continually adapted to enable scenario analysis of settings or policies being considered at the time (e.g. elimination of community transmission versus disease control). Model scenarios were co-designed with government, to fill evidence gaps prior to key decisions. RESULTS Understanding outbreak risk following incursions was critical to eliminating community COVID-19 transmission. Analyses showed risk depended on whether the first detected case was the index case, a primary contact of the index case, or a 'mystery case'. There were benefits of early lockdown on first case detection and gradual easing of restrictions to minimise resurgence risk from undetected cases. As vaccination coverage increased and the focus shifted to controlling rather than eliminating community transmission, understanding health system demand was critical. Analyses showed that vaccines alone could not protect health systems and need to be complemented with other public health measures. CONCLUSIONS Model evidence offered the greatest value when decisions needed to be made pre-emptively, or for questions that could not be answered with empiric data and data analysis alone. Co-designing scenarios with policy-makers ensured relevance and increased policy translation.

Abstract
BACKGROUND There are few community-based lifestyle interventions designed to target physical and mental health of men. We conducted a qualitative focus group study with men to explore their perceived barriers and facilitators to uptake and engagement with interventions designed to improve their physical and mental health and wellbeing. METHODS A volunteer sampling approach (advertisements posted on a premier league football club's social media) was used to recruit men aged 28 to 65 years who were interested in improving their physical and/or mental health and wellbeing. Focus group discussions were conducted at a local premier league football club to 1) explore men's perceived barriers and facilitators to uptake of community-based interventions; 2) identify health issues considered important to address; 3) obtain participant views on how to best engage men in community-based interventions; and 4) use the findings to inform the development of a multibehavioural complex community-based intervention (called 'The 12th Man'). RESULTS Six focus group discussions were conducted (duration 27 to 57 min) involving 25 participants (median age 41 years, IQR = 21 years). Thematic analyses generated seven themes: 'Lifestyle behaviours for both mental health and physical health'; 'work pressures are barriers to engaging with lifestyle behaviour change'; previous injuries are barriers to engagement in physical activity and exercise'; personal and peer group relationships impact on lifestyle behaviour change'; relationships between body image and self-confidence on mastery of skills for physical activity and exercise'; building motivation and personalised goal setting'; and 'credible individuals increase uptake and continued engagement with lifestyle behaviour change'. CONCLUSIONS Findings suggest that a multibehavioural community-based lifestyle intervention designed for men should promote parity of esteem between physical and mental health. It should also acknowledge individual needs and preferences, emotions in the context of goal setting and planning, and be delivered by a knowledgeable and credible professional. The findings will inform the development of a multibehavioural complex community-based intervention ('The 12th Man').

Abstract
Occupational burnout is a significant global problem that has impacted clinical outcomes, patient safety, and patient-centered care across healthcare settings (World Health Organization) [WHO], 2019. The classic definition of burnout, as defined by Dr. Christina Maslach, is “a psychologic syndrome involving emotional exhaustion, depersonalization, and a diminished sense of personal accomplishment (Maslach & Jackson, 1982). Burnout affects cognitive, behavioral and emotional aspects of human behavior. It also interferes with how individuals process and interact with others at an individual and organizational level. Others have noted that burn-out individuals tend to focus on negative things rather than positive emotions (Bianchi & Laurent, 2015). Nurse and physician burnout was recognized before the COVID-19 pandemic as a growing problem. Evidence now suggests that more than 50% of nurses, physician assistants and physicians report syndromes of burnout. The problem has become even more pronounced when the work environment contributes stressors associated with technological advancements, EMRs, increased patient acuity, and financial cost cutting measures. It is now recognized that individuals and organizations burnout. As a public health issue, burnout and well-being are multifactorial and recognize that individuals and organizations contribute significant factors to the burnout syndrome. It appears that burnout rates are rising across specialties and settings resulting in increase of costs to individuals and organizations (National Academy of Medicine [NAM]), 2018. What is needed is a clear map to make decisions on clinical burnout. Healthcare workers (HCW) need confidential access to wellness activities, support systems and mental health consultation. A new model is needed to further refine the work-life balance and create a caring corporate culture. Healthcare leaders need to rethink how to support employees across disciplines when it comes to burnout and well-being.

Abstract
Since 2014, the National Lung Cancer Audit (NLCA) has been evaluating the performance of the UK NHS lung cancer services against established standards of care. Prior to the onset of the COVID-19 pandemic, the NLCA's annual reports revealed a steady stream of improvements in early diagnosis, access to surgery, treatment with anti-cancer therapies, input from specialist nursing and survival for patients with lung cancer in the NHS. In January 2022, the NLCA reported on the negative impact COVID-19 has had on all aspects of the lung cancer diagnosis and treatment pathway within the NHS. This article details the fundamental changes made to the NLCA data collection and analysis process during the COVID-19 pandemic and details the negative impact COVID-19 had on NHS lung cancer patient outcomes during 2020.

Abstract
When SARS-CoV-2 Omicron emerged in 2021, S gene target failure enabled differentiation between Omicron and the dominant Delta variant. In England, where S gene target surveillance (SGTS) was already established, this led to rapid identification (within ca 3 days of sample collection) of possible Omicron cases, alongside real-time surveillance and modelling of Omicron growth. SGTS was key to public health action (including case identification and incident management), and we share applied insights on how and when to use SGTS.

Abstract
Introduction Preclinical studies provide foundational knowledge to develop new effective treatments for use in clinical practice. Similar to clinical exercise oncology studies, it is also important to monitor, identify and/or avoid cancer-induced complications in preclinical (e.g., murine) exercise oncology studies. This may help close the gap between preclinical and clinical exercise oncology studies. The aim of the present mini review is to provide insight into exercise protocol design in preclinical exercise oncology studies in order to close the preclinical-clinical gap. A secondary aim was to examine exercise-responsive outcomes in the preclinical versus clinical setting. Method We reviewed animal studies in exercise oncology. A literature search was performed in PubMed/Medline and studies in English were screened. Results We found that the majority of preclinical exercise protocols have not been at least tested clinically. We found some evidence that certain outcomes of preclinical studies (e.g., markers of cellular and molecular adaptation) that translate to clinical studies. However, this translation was dependent on the use, by investigators in their study design, of suitable and applicable preclinical exercise protocols. Conclusions Cancer and its treatment-induced complications (e.g., fatigue, cardiac atrophy, cachexia, etc.) have largely been ignored in the exercise protocols of preclinical oncology studies. Preclinical exercise oncology studies should consider the limitations of human exercise oncology studies when conducting gap analysis for their study design to increase the probability that findings related to mechanistic adaptations in exercise oncology will be translatable to the clinical setting. By virtue of paying heed to patient compliance and adverse effects, clinical exercise oncology research teams must design relevant, feasible exercise protocols; researchers in preclinical exercise oncology should also take such factors into consideration in order to help bridge the gap between preclinical and clinical studies in exercise oncology. Preclinical research provides foundational knowledge for the development of human experimental and clinical studies; however, direct translation of preclinical findings has a low success rate. Exercise can provide potent wide-ranging beneficial effects for people with chronic diseases, including cancer. A minority of preclinical exercise oncology studies account for cancer-related factors in their experimental design. To lessen the preclinical–clinical gap in exercise oncology research, preclinical exercise oncology studies should consider using experimental designs that are based on locomotor activity and/or VO2peak in animals bearing cancer.

Abstract
BACKGROUND Dietary nitrate consumption can increase concentrations of nitrate and nitrite in blood, saliva, and urine. Whether the change in concentrations is influenced by age is currently unknown. OBJECTIVES We aimed to measure changes in nitrate and nitrite concentrations in plasma, urine, and saliva and exhaled NO concentrations after single incremental doses of dietary nitrate in young and older healthy adults. METHODS Twelve young (18-35 y old) and 12 older (60-75 y old) healthy, nonsmoking participants consumed single doses of 100 g, 200 g, 300 g whole beetroot (BR) and 1000 mg potassium nitrate (positive control) ≥7 d apart in a crossover, randomized clinical trial. Plasma nitrate and nitrite concentrations and exhaled NO concentrations were measured over a 5-h period. Salivary nitrate and nitrite concentrations were measured over a 12-h period and urinary nitrate over a 24-h period. Time, intervention, age, and interaction effects were measured with repeated-measures ANOVAs. RESULTS Dose-dependent increases were seen in plasma, salivary, and urinary nitrate after BR ingestion (all P ≤ 0.002) but there were no differences between age groups at baseline (all P ≥ 0.56) or postintervention (all P ≥ 0.12). Plasma nitrite concentrations were higher in young than older participants at baseline (P = 0.04) and after consumption of 200 g (P = 0.04; +25.7 nmol/L; 95% CI: 0.97, 50.3 nmol/L) and 300 g BR (P = 0.02; +50.3 nmol/L; 95% CI: 8.57, 92.1 nmol/L). Baseline fractional exhaled NO (FeNO) concentrations were higher in the younger group [P = 0.03; +8.60 parts per billion (ppb); 95% CI: 0.80, 16.3 ppb], and rose significantly over the 5-h period, peaking 5 h after KNO3 consumption (39.4 ± 4.5 ppb; P < 0.001); however, changes in FeNO were not influenced by age (P = 0.276). CONCLUSIONS BR is a source of bioavailable dietary nitrate in both young and older adults and can effectively raise nitrite and nitrate concentrations. Lower plasma nitrite and FeNO concentrations were found in older subjects, confirming the impact of ageing on NO bioavailability across different systems.This trial was registered at www.isrctn.com as ISRCTN86706442.

Abstract
Abstract
Objectives
The profile of thoracic patients and the indications for surgery are becoming increasingly complex. A multidisciplinary perioperative approach can optimise patients, improve outcomes and prevent high-risk patients being inappropriately declined surgery. We aim to retrospectively review the first 100 patients discussed at the CCRM in 2016-17 with a primary outcome of number of on-the-day cancellations. Secondary outcomes include unplanned critical care (HDU) admissions, 30 and 90-day morbidity and mortality.
Method
Data was collected retrospectively for demographics, co-morbidities, lung-function and dynamic testing, diagnosis and proposed surgical approach. CCRM outcomes included need for HDU, requiring further optimisation, change in surgical strategy or patient deemed too high risk.
Results
Average age was 69 years (IQR 12.5) (65 M: 35 F). American Society of Anaesthesiologists’ classification of 3 with predicted of mortality of 2 % (IQR 0.8). Maximal oxygen uptake (VO2 max) was 18.6ml/kg/min (SD ± 4.2). 24 patients were recommended for optimisation and 34 to proceed with HDU. 14 were deemed too high-risk and 30 had a change in surgical strategy. Only 1 patient was cancelled on-the-day due to a recent deterioration in health. 30 and 90-day mortality rates were 1% and 2% respectively, and 2 patients required unplanned HDU.
Conclusions
CCRM is a simple approach to optimise high-risk patients and minimise unplanned HDU. No patients were cancelled on-the-day due to inadequate optimisation or unexpected need for HDU. Mortality was acceptable and lower than predicted. Our study established CCRM as a safe and effective way of selecting high-risk patients for further optimisation and appropriate perioperative care.

Abstract
PURPOSE The article presents the results of research on psychosocial aspects of living with cancer in the Slovak Republic focusing on hospitalized and outpatient cancer patients in treatment during the curative stage of the disease. Assessing cancer patient's interest in receiving help from individual members of a multidisciplinary team was a part of the research. METHODS The research was done through a questionnaire designed to focus on individual psychosocial aspects of cancer treatment. The research sample included 67 hospitalized patients and 61 outpatients. Execution of research was conducted in the individual clinical workplaces. RESULTS When calculating the interest of cancer patients in spiritual counseling during oncological treatment, hospitalized patients indicated significant interest (p = .014). Similarly, hospitalized patients indicated more interest in using psychological counseling (p = .040) as well as in consultation with the social worker with a significant difference of (p = .017). Interest in the aid of a physical therapist was exhibited more significantly with hospitalized patients (p = .000). Significant interest in hospitalized patients using additional members of the multidisciplinary team was statistically significant (p = .017). Outpatient cancer patients indicated significant interest in finding information about medical conditions on the Internet (p = .000). For items addressing an interest in meeting people with cancer in self-help groups, there was no significant difference between outpatient and hospital patients (p = .298) as with talking to other patients who had cancer (p = .207). CONCLUSION External support factors are important in helping patients cope with cancer. Health professionals can help patients mitigate the various difficulties associated with cancer.

Abstract
Thousands of healthcare and social workers (HCSW) died or lost their ability to work in their field after Covid pandemics in all three waves, and thousands left their profession due to burnout syndrome. Despite development of vaccines took 6- 18 months and refreshment of old molecules for treatment weeks, many countries paid a very high price for this pandemics not due to lack of medications or ventilator assistance devices but due to the increasing lack of trained HCSW.

Abstract
BackgroundThe loaded countermovement jump (CMJ) is a variation on the normal CMJ (bodyweight-only), used routinely in sport settings as a measure of neuromuscular fatigue (NMF). Although commonplace, the CMJ variables that are most sensitive to NMF remain somewhat unclear.PurposeThe aim of this study was to examine the relationship between changes in workload and changes in the loaded CMJ; specifically, to determine its suitability for assessment of NMF.MethodsEighteen professional rugby union players performed loaded CMJ tests on seven occasions over the course of thirteen weeks, during an English top-flight season. Eight CMJ variables were measured, assessing different aspects of the CMJ. Workload was measured by GPS total distance and was the sum of the previous week’s data, recorded in on-field training and match-play. Spearman’s rank-order correlations were calculated to identify the relationship between changes in workload and changes in loaded CMJ variables.ResultsNo significant relationships were found between loaded CMJ variables and workload with no lag or workload lagged one week. Significant relationships were found between workload lagged 2 weeks and flight time/contact time (FT-CT; rs=-0.35; p=0.04) and time to peak power (TtPP; rs=0.35; p=0.05).ConclusionThis study suggests loaded CMJ is not a suitable test to monitor acute changes to NMF. However, results also indicate that FT-CT and TtPP, are associated with changes in workload lagged 2-weeks. Therefore, certain CMJ variables may prove useful to help prescribe alterations to athlete training plans following periods of heavy workload.

Abstract
Aim This pilot study aimed to investigate whether a 4-week programme of intermittent high-intensity training (HIT) will improve counterregulatory responses and improve hypoglycaemia awareness in adults with type 1 diabetes who have been exposed to recurrent hypoglycaemia. Methods Adults with type 1 diabetes who have been exposed to recurrent hypoglycaemia will be recruited from NHS Tayside, Scotland. All participants have a 4-week run-in period to optimize glycaemic control and to receive instruction in hypoglycaemia avoidance using insulin dose adjustment and real-time continuous glucose monitoring (CGM). Following this, they will undergo a baseline 90-minute hyperinsulinaemic hypoglycaemic clamp to assess symptomatic, cognitive and hormonal counterregulatory responses. Subsequently, participants will be randomized in a parallel-group design to either undergo a 4-week intervention with HIT or to no exercise with both groups using CGM throughout and receiving additional advice on hypoglycaemia avoidance. Participants in the HIT arm of the trial will be instructed to exercise 3 times a week on a cycle ergometer and asked to achieve ≥ 90% max heart rate during each period of exercise. On completion of the intervention period, all subjects then undergo a second matched hyperinsulinaemic hypoglycaemic clamp study. Discussion This pilot study will determine whether high-intensity exercise may offer a novel approach to restore hypoglycaemic awareness in type 1 diabetes (International Standard Randomised Controlled Trials No: ISRCTN15373978).

Abstract
AIMS/HYPOTHESIS Approximately 25% of people with type 1 diabetes have suppressed counterregulatory hormonal and symptomatic responses to insulin-induced hypoglycaemia, which renders them at increased risk of severe, disabling hypoglycaemia. This is called impaired awareness of hypoglycaemia (IAH), the cause of which is unknown. We recently proposed that IAH develops through habituation, a form of adaptive memory to preceding hypoglycaemia. Consistent with this hypothesis, we demonstrated restoration of defective counterregulatory hormonal responses to hypoglycaemia (referred to as dishabituation) in a rodent model of IAH following introduction of a novel stress stimulus (high intensity training [HIT]). In this proof-of-concept study we sought to further test this hypothesis by examining whether a single episode of HIT would amplify counterregulatory responses to subsequent hypoglycaemia in people with type 1 diabetes who had IAH (assessed by Gold score ≥4, modified Clarke score ≥4 or Dose Adjustment For Normal Eating (DAFNE) hypoglycaemia awareness rating 2 or 3). The primary outcome was the difference in adrenaline response to hypoglycaemia following both a single episode of HIT and rest. METHODS In this randomised, crossover study 12 participants aged between 18 and 55 years with type 1 diabetes for ≥5 years and an HbA1c <75 mmol/mol (9%) were recruited. Individuals were randomised using computer generated block randomisation to start with one episode of HIT (4 × 30 s cycle sprints [2 min recovery] at 150% of maximum wattage achieved during [Formula: see text] assessment) or rest (control). The following day they underwent a 90 min hyperinsulinaemic-hypoglycaemic clamp study at 2.5 mmol/l with measurement of hormonal counterregulatory response, symptom scores and cognitive testing (four-choice reaction time and digit symbol substitution test). Each intervention and subsequent clamp study was separated by at least 2 weeks. The participants and investigators were not blinded to the intervention or measurements during the study. The investigators were blinded to the primary outcome and blood analysis results. RESULTS All participants (six male and six female, age 19-54 years, median [IQR] duration of type 1 diabetes 24.5 [17.3-29.0] years, mean [SEM] HbA1c 56 [3.67] mmol/mol; 7.3% [0.34%]) completed the study (both interventions and two clamps). In comparison with the rest study, a single episode of HIT led to a 29% increase in the adrenaline (epinephrine) response (mean [SEM]) (2286.5 [343.1] vs 2953.8 [384.9] pmol/l); a significant increase in total symptom scores (Edinburgh Hypoglycaemia Symptom Scale: 24.25 [2.960 vs 27.5 [3.9]; p<0.05), and a significant prolongation of four-choice reaction time (591.8 [22.5] vs 659.9 [39.86] ms; p<0.01] during equivalent hypoglycaemia induced the following day. CONCLUSIONS/INTERPRETATION These findings are consistent with the hypothesis that IAH develops in people with type 1 diabetes as a habituated response and that introduction of a novel stressor can restore, at least partially, the adapted counterregulatory hormonal, symptomatic and cognitive responses to hypoglycaemia.

Abstract
Young-onset Parkinson's disease (YOPD), defined by onset at <50 years, accounts for approximately 10% of all Parkinson's disease cases and, while some cases are associated with known genetic mutations, most are not. Here induced pluripotent stem cells were generated from control individuals and from patients with YOPD with no known mutations. Following differentiation into cultures containing dopamine neurons, induced pluripotent stem cells from patients with YOPD showed increased accumulation of soluble α-synuclein protein and phosphorylated protein kinase Cα, as well as reduced abundance of lysosomal membrane proteins such as LAMP1. Testing activators of lysosomal function showed that specific phorbol esters, such as PEP005, reduced α-synuclein and phosphorylated protein kinase Cα levels while increasing LAMP1 abundance. Interestingly, the reduction in α-synuclein occurred through proteasomal degradation. PEP005 delivery to mouse striatum also decreased α-synuclein production in vivo. Induced pluripotent stem cell-derived dopaminergic cultures reveal a signature in patients with YOPD who have no known Parkinson's disease-related mutations, suggesting that there might be other genetic contributions to this disorder. This signature was normalized by specific phorbol esters, making them promising therapeutic candidates.

Abstract
Six foods representing a variety of food products were analyzed by the Assurance Listeria polyclonal enzyme immunoassay (EIA) and by either the Bacteriological Analytical Manual or the U.S. Department of Agriculture culture method for detecting Listeria monocytogenes and related Listeria species. Samples of each food type, at each inoculation level, were analyzed simultaneously by both methods. A total of 19 laboratories representing federal government agencies and private industry in the United States and Canada participated. Food types were inoculated with Listeria species including L. monocytogenes, with the exception of 3 lots of green beans, which were naturally contaminated. During this study, 1764 samples and controls were analyzed and confirmed, of which 492 were positive and 947 were negative by both methods. There were 159 samples that were positive by culture method but negative by the EIA and 188 that were negative by culture method but positive by EIA. Twenty-two samples were negative by EIA and by culture method but confirmed positive when Assurance selective enrichment broths were subcultured to selective agar. The Assurance polyclonal EIA for detecting L. monocytogenes and related Listeria species in foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
Five foods types were analyzed by the Assurance EHEC (Escherichia coli 0157:H7) enzyme immunoassay (EIA) and by the Bacteriological Analytical Manual (BAM) culture method. Each sample of each food type at each inoculation level was simultaneously analyzed by both methods. A total of 21 laboratories representing state and federal government agencies and private industry in the United States and Canada participated. Samples were inoculated with E. coli 0157:H7, except for one lot of poultry that was naturally contaminated. A total of 1304 samples and controls were analyzed and confirmed, of which 473 were positive and 818 were negative by both methods. Thirteen samples were positive by BAM but negative by EIA. Because of the study design, it was not possible for the BAM method to produce false-negative or falsepositive results. The Assurance method for detection of E. coli OI57:H7 in selected foods has been adopted first action by AOAC INTERNATIONAL.

Abstract
A total of 19 government and private industry laboratories in Canada and the United States participated in the collaborative study. Naturally contaminated ground poultry and animal meals, as well as inoculated raw shrimp, were examined for presence of Salmonella by both the modified immunodiffusion method and the Bacteriological Analytical Manual culture method, resulting in an agreement rate of 93.1%. The 2 methods are statistically equivalent for all food types at each inoculation level and for all lots of naturally contaminated foods evaluated in this study. The modification of the AOAC Official Method 989.13, immunodiffusion (1–2 TEST) method for detection of motile Salmonella in all foods, has been adopted revised first action by AOAC INTERNATIONAL.

Abstract
Six foods representative of a wide variety of processed, dried powder processed, and raw food types were analyzed by the Assurance® Gold Salmonella Enzyme Immunoassay (EIA) and AOAC INTERNATIONAL culture method. Paired samples of each food type were simultaneously analyzed; one sample by the Assurance method and one by the AOAC culture method. The results for Assurance method were read visually and instrumentally with a microplate reader. A total of 24 laboratories representing federal government agencies and private industry, in the United States and Canada, participated in this collaborative study. Food types were inoculated with species of Salmonella with the exception of raw ground chicken, which was naturally contaminated. No statistical differences (p < 0.05) were observed between Assurance Gold Salmonella EIA with either visual or instrumental interpretation and the AOAC culture method for any inoculation level of any food type or naturally contaminated food. The Assurance visual and instrumental options of reading sample reactions produced the same results for 1277 of the 1296 sample and controls analyzed.

Abstract
OBJECTIVE: The study has aimed to explore the process, outcomes of primary care, and barriers that make the primary care access difficult for the patients.
DESIGN & SETTING: The study has utilized quantitative and qualitative approach and collected data from the clinic and patients. Patient survey was conducted to ask the patients about the possible reasons, which prevent them from accessing primary care services in the past.
RESULTS: The mean age of patients was 46 years, among which majority (65%) were males. The results showed that education was the significant factor in determining the health status of a specific population. The clinic was successfully integrated into the behavioral health care setting. Many patients had been enrolled in the clinic for the first time with the help of a care manager that facilitated the identification of those patients. Most commonly, transportation was the main barrier for those populations for not seeking the primary care services. Emergency department use significantly declined after the implementation of the new model that reduced the cost of health services dramatically in a short period of time i.e. 6 months.
CONCLUSION: There are susceptical gaps within the fragmented care due to high rates of physical health conditions. Majority of the patients in the study sample were satisfied with the new model; therefore, the new model was termed as effective and efficient.

Abstract
Background: Acne vulgaris is a common, often socially distressing skin condition primarily seen in young adults. Quality of life studies have shown that people with acne are more introverted with increased social setting anxiety compared to a control group. Unfortunately, patients with acne may have residual postinflammatory hyperpigmentation, amplifying impaired psychosocial effects. Objective: To quantify the impact of postinflammatory hyperpigmentation in patients with acne using a psychometric scale. Design: A clinic-based survey was conducted among US adults with facial acne and postinflammatory hyperpigmentation. Outcomes included age, race, gender, and acne-related quality of life. A board-certified dermatologist rated each patient's acne severity and postinflammatory hyperpigmentation. Setting: Dermatology clinic, Anheuser Busch Institute and Des Peres Hospital, Saint Louis, Missouri. Participants: 48 subjects (25 patients with acne and postinflammatory hyperpigmentation; 23 with acne only). Measurements: Acne Quality of Life survey, dermatologist rating of acne and postinflammatory hyperpigmentation severity. Results: Subjects with postinflammatory hyperpigmentation reported statistically significant poorer mean scores on the Acne Quality of Life survey than subjects with acne only. Sixty percent of patients with postinflammatory hyperpigmentation had a "very markedly" impact to at least one aspect of the Acne Quality of Life survey scale compared to none of the acne only patients. There was no association between provider-reported hyperpigmentation severity and psychosocial impact. No differences in psychosocial impact were noted between males and females. Conclusion: Patients with acne and postinflammatory hyperpigmentation had poorer quality-of-life scores compared to patients with only acne. Having postinflammatory hyperpigmentation with acne negatively impacted self-perceptions and social/emotional functioning, especially in groups.

Abstract
A self-adaptive accelerated molecular dynamics method is developed to model infrequent atomic-scale events, especially those events that occur on a rugged free-energy surface. Key in the new development is the use of the total displacement of the system at a given temperature to construct a boost-potential, which is slowly increased to accelerate the dynamics. The temperature is slowly increased to accelerate the dynamics. By allowing the system to evolve from one steady-state configuration to another by overcoming the transition state, this self-evolving approach makes it possible to explore the coupled motion of species that migrate on vastly different time scales. The migrations of single vacancy (V) and small He-V clusters, and the growth of nano-sized He-V clusters in Fe for times in the order of seconds are studied by this new method. An interstitial-assisted mechanism is first explored for the migration of a helium-rich He-V cluster, while a new two-component Ostwald ripening mechanism is suggested for He-V cluster growth.
