Abstract
BACKGROUND The COVID-19 pandemic has posed an unprecedented challenge to healthcare systems globally. Personal protective equipment has played a fundamental role in protecting healthcare workers and patients, but its effectiveness in reducing hospital-acquired infections (HAIs) during the pandemic remains a subject of debate. AIM To conduct a synthesis and meta-analysis of the best available evidence of the prevalence of HAIs using a before/after approach. METHODS A three-step search strategy was undertaken to locate published and unpublished studies. A search was performed in MEDLINE, CINAHL, Embase, PsycINFO, and Google Scholar. Screening of studies, data extraction and critical appraisal were performed by four independent reviewers. Meta-analysis was conducted using Review Manager. The review is reported in accordance with PRISMA and JBI guidelines for systematic reviews. FINDINGS Fifteen studies were included in the review. Three studies indicated a statistically significant increase in the number of positive cultures during the COVID-19 period compared to the pre-COVID-19 period. Pooled data showed a non-significant decrease in the number of patients with positive cultures in the COVID-19 period compared to pre-COVID-19. There were no significant differences in various bacterial infections except for a significant decrease in respiratory infections. Pooled data for central line-associated bloodstream infections (CLABSIs) indicated a significant increase during the COVID-19 period, but one study reported an increase in CLABSI incidence. CONCLUSION The evidence from this review demonstrates a mixed impact of the COVID-19 pandemic precautions on HAIs.

Abstract
OBJECTIVES To evaluate the predictive factors for biochemical failure and distant metastases in a prospective cohort of patients with localized prostate cancer treated with the combination of HDR BT and EBRT. METHODS AND MATERIALS Patients with intermediate (IR) or high-risk (HR) prostate adenocarcinoma received a single fraction of HDR of 15 Gy combined with RT of 37.5 Gy in 15 fractions. ADT duration was used depending on risk-group. Descriptive analyses were performed. Univariate and multivariate Hazard Ratios were obtained. Finally, the Kaplan-Meier model was used to describe the survival of the events of interest. RESULTS 309 patients were treated prospectively (199 were IR and 110 HR). Median age was 72 years; 58.3 % were MRI stage ≤ T2c, 34.1 % T3a and 7.6 % T3b; ISUP-grade 1-3 in 78.9 % and ISUP 4-5 in 21.1 %. 71.8 % of patients had ≤ 50 % positive-cores in biopsy and 28.2 % had > 50 %. Median pre-treatment PSA was 9.9 ng/mL. After a median follow-up of 88 months, 41 patients presented biochemical failure and 18 developed distant metastases. Multivariate cox-regression analyses found that MR-T3b Stage (HR 3.88, p = 0.001) and ADT use (HR 3.99, p = 0.03) were the only predictive factors for biochemical failure and the number of positive cores (>50 %) the only independent predictive factor of distant metastases (HR 4.36, p = 0.002). CONCLUSIONS Patients with mpMRI evidence of invasion of the SV and involvement of more than 50% of the cores in the prostate biopsy are patients with a higher risk of presenting a biochemical recurrence or developing metastasis due to their prostate cancer, respectively.

Abstract
BACKGROUND Radiolabeled fibroblast activation protein (FAP) ligands, a novel class of tracers for PET/CT imaging, have demonstrated very promising results in various oncological, as well as in some benign, diseases with long-term potential to supplant the current pan-cancer agent [18F]FDG in some cancer types. Pancreatic ductal carcinoma (PDAC) belongs to the group of epithelial malignancies with a strong so-called "desmoplastic reaction", leading to a prominent tumor stroma with cancer-associated fibroblasts that exhibit a marked overexpression of fibroblast activation protein (FAP). The first clinical experiences in PDAC with 68Ga-labeled FAP ligands suggested superior sensitivity to [18F]FDG. However, there is limited data with 18F-labeled FAP derivatives, i.e. [18F]FAPI-74, yet prospective single- and multicenter trials are already ongoing. In this proof-of-concept study, we sought to evaluate the biodistribution, tumor uptake, and lesion detectability in patients with PDAC using [18F]FAPI-74 PET/CT as compared to [18F]FDG PET/CT scans for staging. METHODS This study includes 7 patients (median age 69) who underwent both [18F]FDG PET/CT with contrast-enhancement and [18F]FAPI-74 PET with low-dose CT for primary staging (n = 3) and therapy response control after neoadjuvant (n = 1) or re-staging after palliative therapy (n = 3). The mean interval between PET scans was 11 ± 4 days (range 1-15 days). The [18F]FDG and [18F]FAPI-74 PET/CT scans were acquired at 64 ± 4.1 min (range 61-91 min) and 66.4 ± 6.3 min (range 60-76 min), respectively, after administration of 200 ± 94 MBq (range 79-318 MBq) and 235 ± 88 MBq (range 90-321 MBq), respectively. Quantification of tracer uptake was determined with SUVmax and SUVmean. Furthermore, the tumor-to-background ratio (TBR) was derived by dividing the SUVmax of tumor lesions by the SUVmax of adipose tissue, skeletal muscle, and blood pool. RESULTS Overall, 32 lesions were detected in 7 patients including primary (n = 7), lung (n = 7), bone (n = 3), lymph node (n = 13), and peritoneal metastases (n = 2). [18F]FAPI-74 detected 22% more lesions compared with [18F]FDG with a better TBR and visual lesion delineation. In one patient the primary lesion could be detected unequivocally with [18F]FAPI-74 but was missed by [18F]FDG imaging. Altogether, most of the lesions demonstrated markedly elevated uptake of [18F]FAPI-74 with a simultaneous lower uptake in the background, providing a very high visual contrast. CONCLUSION To the best of our knowledge, this is the first, prospective, intra-individual investigation comparing [18F]FAPI-74 with [18F]FDG imaging in PDAC with encouraging results. These pivotalresults supporta larger, multicentric, prospective study to determine the value of [18F]FAPI-74 in detecting and staging PDAC in comparison with current standard of care imaging.

Abstract
The COVID-19 pandemic has profoundly impacted the way general practice is run and this is expected to have had a knock-on effect upon GP training. A questionnaire-based study was designed to investigate what was happening to GP trainees 16 months into the pandemic in terms of opportunities to develop clinical experience and clinical decision-making. We also asked trainers and trainees for ideas on how we might mitigate for the effects of COVID-19. In particular, there has been decreased exposure to clinical examination during the pandemic and there appear to be gaps in opportunities to learn from urgent and unscheduled care settings and to develop skills in rapid clinical decision-making. It is interesting to consider what general practice will look like when the pandemic is over and how this will this affect the GP training curriculum going forwards. Although response rates were low, we were able to determine some emerging themes for national, local and educational review going forwards to help shape and improve GP training for the future.

Abstract
Background The social and economic impacts that have occurred during the pandemic can disproportionally affect those already experiencing poverty. The social determinants of health aggravate inequalities and can adversely affect wellbeing. This study aims to gain rich insight into Australian adults’ experiences of the social determinants of health and the impact on their wellbeing during the COVID-19 pandemic. Methods A descriptive qualitative study using purposive sampling to recruit participants for semi-structured interviews, conducted via videoconferencing between March-August 2021. Thematic analysis was performed with the support of NVivo 12. Results Participants included 20 Australian adults from various socioeconomic areas ranging in age from 21 to 65 years. Three main themes emerged from the analysis of the data: Food-related concerns; Housing outcomes; and Psychological and emotional impact. Accessing food, during the COVID-19 pandemic, for most participants who resided in low socioeconomic areas, was described as stressful and challenging. Along with the burden of food security, many participants from low socioeconomic areas expressed emotional distress in relation to securing and maintaining adequate housing. Conclusions The pandemic has amplified existing social determinants of health experienced by those within low socioeconomic areas, particularly those who are female and from migrant communities. The wellbeing of participants from low socioeconomic areas decreased in response to their experiences and challenges with food insecurity and housing instability, highlighting the need for housing affordability strategies and funding of emergency food relief initiatives. Food access for those in areas with high socioeconomic disadvantage, can be improved to address some of the barriers associated with food security by providing supermarket meal vouchers, access to community gardens, and school food programs. Key messages • The housing and food insecurity experienced by participants in this study during the pandemic has influenced their overall wellbeing. • The pandemic has amplified existing social determinants of health experienced by those in low socioeconomic areas.

Abstract
Abstract
Background
There is a controversy about correlation between voltage and thickness in the atrial myocardium and their evolution from paroxysmal to persistent atrial fibrillation (AF).
Purpose
This is an observational study to compare voltage and thickness of different areas on the left atrium in paroxysmal and persistent atrial fibrillation.
Methods
Twenty-one patients underwent atrial fibrillation ablation. Points with electrical information from an electroanatiomical map in sinus rhythym were acquiered during the ablation procedure covering the whole atrial surface. CT was acquired in all patients before the procedure and endo- and epicardium from the atrium was segmented for the atrial thickness calculation. All the points from the electromecanical map were projected on the thickness map to have both information on the same location. 3D atrium was segmented in 5 areas for the analysis: Lateral, Anterior, Septal, Inferior-Posterior and Superior-Posterior (Figure 1). Voltage and thickness values among different areas and between AF type were compared.
Results
11 paroxysmal and 10 persistent AF patients were analyzed acquiring 452±207 points per patient and 1897±750 points per area. There was no linear correlation between voltage and thickness comparing all the patients nor among different areas nor between AF type (R<0.2 in all cases).
Regarding paroxysmal AF patients, septum showed significatly lower voltage compared with the other segments, posterior, lateral, anterior and roof (1.3±1.4, 2±1.8, 2±1.6, 1.7±1.5, 2±1.6, P<0.001). Posterior segment showed the highest voltage. The thickness analysis showed the septum segment as thinner segment and lateral as thicker segment (1.3±1.5,1.7±0.8, P<0.001) (Figure 2).
Regarding persisten AF patients: septum showed significatly lower voltage compared with the other segments, posterior, lateral, anterior and roof who shows higher voltage (1±0.8*, 1.5±1.2, 1.9±1.7, 1.5±1.4, 2±1.6) (Figure 2). The thickness analysis showed the anterior segment as thinner segment and lateral as the thickest segment (1.6±0.8, 1.9±0.9 (P<0.001), different like on paroxysmal AF population.
Comparing voltage and thicknes between paroxysmal and persistent AF, all the segments on persistent population showed lower voltage values, with significant differences on septal, posterior and anterior walls (1±0.8 vs 1.3±1.4, 1.5±1.2 vs 2±1.8, 1.5±1.4 vs 1.7±1.5, P<0.001). On the other hand, all segments on persistent population showed statisticaly signignificant thicker myocardium in camparison with paroxysmal population (Figure 2).
Conclusions
According to our findings, there is no linear correlation between voltage and thickness. Persistent AF atria show thicker walls but with lower voltages in comparison with paroxysmal AF atria.

Abstract
Mixtures of cohesive clay and noncohesive sand are widespread in many aquatic environments. Ripple dynamics in sand-clay mixtures have been studied under current-alone and wave-alone conditions but not combined wave-current conditions, despite their prevalence in estuaries and the coastal zone. The present flume experiments examine the effect of initial clay content, C 0, on ripples by considering a single wave-current condition and, for the first time, quantify how changing clay content of substrate impacts ripple dimensions during development. The results show inverse relationships between C 0 and ripple growth rates and clay winnowing transport rates out of the bed, which reduce as the ripples develop toward equilibrium. For C 0 ≤ 10.6%, higher winnowing rates lead to clay loss, and thus the presence of clean sand, far below the base of equilibrium ripples. This hitherto unquantified "deep-cleaning" of clay does not occur for C 0 > 10.6%, where clay-loss rates are much lower. The clay-loss behavior is associated with two distinct types of equilibrium combined flow ripples: (a) Large asymmetric ripples with dimensions and plan geometries comparable to their clean-sand counterparts for C 0 ≤ 10.6% and (b) small, flat ripples for C 0 > 10.6%. The 10.6% threshold, which may be specific to the experimental conditions, corresponds to a more general 8% threshold found beneath the ripple base, suggesting that clay content here must be <8% for clean-sand-like ripples to develop in sand-clay beds. This ripple-type discontinuity comprises a threefold reduction in ripple height, with notable implications for bed roughness.

Abstract
BACKGROUND Chagas disease is endemic throughout most of Bolivia, with prevalence rates of 25% observed in some geographic areas located mainly in the sub-Andean region. METHODS Community-based entomological surveillance was carried out in the sub-Andean departments of Cochabamba (municipalities of Cochabamba, Punata and Sacaba), Tarija (municipality of Tarija) and Chuquisaca (municipality of Sucre). The surveillance parameters evaluated were: (i) the proportion of cards with the presence of triatomines; (ii) the distribution of positive cards by area; and (iii) the proportion of cards with the presence of infected triatomines. RESULTS Of the cards returned, in 852 (3.1%) there was a mention of the presence of triatomines. The species Triatoma infestans, Triatoma sordida and Triatoma guasayana were identified in 812 (95.3%), 39 (4.6%) and 1 (0.1%), respectively. The median monthly positivity rate of the cards during 2011-2018 was higher in Punata (9.1%; IQR=3.2-15.4%). The median monthly rate was highest in 2012 (2.7%; IQR=0-5.6%). Fifty positive cards (5.8%) presented insects that were positive for trypanosomatids, mainly in Cochabamba and Punata. CONCLUSIONS The report of triatomines foci by inhabitants represents an effective surveillance system coordinated by a network of specialized and multidisciplinary health centers. These strategies, which should be included in the health policies of endemic countries, enable extending and deepening the dialogue among technicians, communities and their local authorities.

Abstract
Introduction The emergence of COVID-19 has created global transmission. While effective at reducing the spread, public health measures implemented may impact individuals differently leaving them susceptible to the detrimental effects on their health and wellbeing. Therefore this review aims to synthesise the best available evidence on the relationship between the social determinants of health and health outcomes among adults during the COVID-19 pandemic. Methods A three-step search strategy was used to find both published and unpublished papers. The databases searched included: MEDLINE, CINAHL, EMBASE, and Google Scholar. Following the search, all identified citations were uploaded into Endnote X9, with duplicates removed. Methodological quality of eligible papers was assessed independently by two reviewers, with meta-synthesis conducted in accordance with JBI methodology. Results Fifteen papers were included. Three synthesized conclusions were established a) Vulnerable populations groups, particularly those from a racial minority and those with low incomes, are more susceptible and have been disproportionately affected by COVID-19 including mortality; b) Gender inequalities and family violence have been exacerbated by COVID-19, leading to diminished wellbeing among women; and c) COVID-19 is exacerbating existing social determinants of health through loss of employment/income, disparities in social class leading to lack of access to healthcare, housing instability, homelessness and difficulties in social distancing. Conclusions Vulnerable population groups have been disproportionately impacted by COVID-19, including health outcomes such as hospitalisations and mortality. The COVID-19 pandemic has highlighted the need for action on health inequalities and the social determinants of health. Reflection on social and health policies implemented are necessary to ensure that the COVID-19 pandemic does not exacerbate health inequalities into the future. Key messages Vulnerable populations including racial minority groups and low income earners have been disproportionately impacted by COVID-19. Action on social determinants of health is required to ensure COVID-19 does not exacerbate health inequalities into the future.

Abstract
Background The COVID-19 pandemic has had effects on populations worldwide. The social determinants of health affect an individual's capacity to cope during a crisis which could potentially impact on their wellbeing. The aim of this study was to examine the relationship between wellbeing and the social determinants of health among Australian adults during the COVID-19 pandemic. Methods A cross-sectional study of adults residing in Australia was conducted using SurveyMonkey (an online survey) between August - October 2020. Participants were recruited via social media. Wellbeing was measured using the 10-item Multicultural Quality of Life Index and social determinants of health were measured using validated tools and investigator developed questions. Data were analysed using SPSS version 25. Inferential statistics, including independent t-test and one-way ANOVA were undertaken. Multiple regression analysis was used to investigate the predictors of wellbeing. Results In total, 1211 responses were received. Females accounted for 80.7% of the responses, men 16.7% and transgender/non-binary 2.6%. The mean age of the respondents was 43 years (SD 14.5). The mean score for total wellbeing was 62.58 (SD 21.22). Housing insecurity (p = 0.000), food insecurity (p = 0.000, social support (p = 0.000) and access to health care (p = 0.000) were all predictors of poor total wellbeing. Being a male (p = .0380) was the only predictor of higher wellbeing. Conclusions This study demonstrates that adults in Australia who had poor social support, had difficultly accessing health care, had insecure housing and food insecurity had significantly poorer wellbeing during the COVID-19 pandemic. This study exposes the social determinants of health that are responsible for health and social inequalities. It shows that the COVID-19 pandemic has exacerbated the social vulnerabilities and highlights the need take action on the social determinants of health and inequalities. Key messages The COVID-19 pandemic has further exposed the longstanding health and social inequalities that exist in Australia. Action on social determinants of health is required in a post COVID-19 world to rebuild social protection and safeguard populations from any future public health emergencies.

Abstract
We evaluated the potential for mosquitoes collected in the Amazon Basin, near Iquitos, Peru, to become infected with and transmit Murutucu (MURV) and Itaqui viruses (ITQV) (Order Bunyavirales, Family: Peribunyaviridae, Genus: Orthobunyavirus). Viremia levels in Syrian hamsters peaked 2 d after infection with either virus, and both viruses were highly lethal in hamsters with virtually all hamsters dying prior to 3-d postinfection. For almost all of the mosquito species tested some individuals were susceptible to infection and some developed a disseminated infection after oral exposure to either MURV or ITQV. However, only the Culex species (Culex (Culex) coronator Dyar and Knab [Diptera, Culicidae], Culex (Melanoconian) gnomatos Sallum, Huchings, and Ferreira [Diptera, Culicidae], Culex (Mel.) pedroi Sirivanakarn and Belkin [Diptera, Culicidae], and Culex (Mel.) vomerifer Komp [Diptera, Culicidae]) successfully transmitted virus by bite. However, even among these species, only about 37% of the individuals with a disseminated infection successfully transmitted these viruses, indicating a significant salivary gland barrier. Although little is known about the medical or veterinary importance of many members of the genus Orthobunyavirus, we have demonstrated that Culex spp. (Diptera, Culicidae) could be potential vectors.

Abstract
Previous studies found that calcium sensing receptor (CaSR) it's expressed in intercalated cells of the collecting duct and that its activation by calcium in the luminal membrane promotes acidification of urine. Therefore, the aim of the study was to analyze the effects of CaSR stimulus on the biochemical activity of the vacuolar H+-ATPase in a cellular model of intercalated cells, MDCK-C11 cells. Biochemical activity of H+-ATPase was performed using cell homogenates and the inorganic phosphate released was determined by a colorimetric method. Changes in cytosolic ionized calcium ([Ca2+]i) were also determined using Fluo-4. A significant increase of vacuolar H+-ATPase activity was observed when the CaSR was stimulated with agonists such as Gd3+ (300 μM), neomycin (200 μM) and by the calcimimetic R-568 (1 μM). This activity was also stimulated in a dose-dependent fashion by changes in extracellular Ca2+ concentration ([Ca2+]o) between 10-2 and 2 mM. The calciolytic NPS 2143 (150 nM) significantly reduced the vacuolar H+-ATPase activity observed with 2 mM [Ca2+]o. Inhibition of phospholipase C (PLC) activity with U73122 (5 x 10-7 M) reversed the increase in pump activity observed in the presence of Gd3+. Activation of CaSR by the specific CaSR agonist R-568 produced a sustained rise of [Ca2+]i, an effect that disappears when extracellular calcium was removed in the presence of thapsigargin. In summary, CaSR stimulation induces an increase in the vacuolar H+-ATPase activity of MDCK-C11 cells, an effect that involves an increase in [Ca2+]i and require PLC activity. The consequent decrease in intratubular pH could lead to increase ionization of luminal calcium, potentially reducing the formation of calcium phosphate stones.

Introduction. Cardiovascular assessment of Marfan syndrome (MS) patients has normally focused on the aortic root and vascular manifestations due to the high risk of aortic dissection.
Although primary myocardial impairment has long been suspected, the evidence has been controversial. Advanced in CMR may support the early detection of cardiac dysfunction. Beyond left ventricle ejection fraction (EF) and myocardial strain (S), a new parameter is emerging, the hemodynamic forces (HF) exchanged between the blood flowing in the heart and the myocardium. The application of these techniques to MS could be useful in demonstrating the presence of primary myocardial impairment.
Aim. The aim of this study is to explore myocardial function in MS through the evaluation in cine CMR of EF, S and cardiac HF exchanged between the blood and the myocardium and compare these data with those of a control group (C).
Methods. We retrospectively analysed CMR cine images of MS (diagnosed according revised Ghent criteria) without valvular disease or previous cardio surgery, and C, in standard long-axis projections, to define endocardial borders for subsequent quantification of left ventricular volumes, EF, longitudinal, circumferential and radial S, apex-to-base and lateral-to-septum HF (expressed in mN and as a percentage of gravity acceleration). The analysis were performed on Medical Imaging Systems (QStrain version 1.3.0.79; MEDIS) (Figure 1).
Results. 108 MS and 44 C had a good quality study, suitable for MEDIS analysis. The mean age was 33 ± 13 ys in MS, 35 ± 12 ys in C; 39% were male in MS, 50% in C.
The results of left ventricular function were: EF 63 ± 7% in MS vs 66 ± 5% in C group, p .008, global longitudinal S -24.5 ± 4.1% in MS vs -26.2 ± 4.1 in C, p .014; global circumferential S -30.6 ± 6.3% in MS vs -33.8 ± 4.4 in C, p .002; radial S 64.5 ± 16.2% in MS vs 72.7 ± 15.9 in C, p .005; apex-to-base HF 13.2 ± 4.7% in MS vs 17.8 ± 7.6% in C, p .000; lateral-to-septum 2.6 ± 1.3% in MS vs 3.1 ± 1.4% in C, p .048.
Moreover, 4.6% MS patients had mid reduced EF (40-50%); 9.2% had global longitudinal S reduction (cut off -19.3%); 7.4% had global circumferential S reduction (cut-off -21.7%).
Conclusion. These data provide support for the existence of a cardiomyopathy in MS. In our opinion, the term "primary cardiomyopathy" is not appropriate to describe this condition: patients with MS have changes in aortic stiffness and probably in cardiac afterload. The HF data are the most interesting of this study, both in the validation of this new parameter and in early detection a cardiomyopathy in MS
Moreover, the reduction of global circumferential S, as wall as global longitudinal S, in MS patients may help provide new elements to characterize the MS cardiomyopathy: sure enough, in literature, circumferential strain abnormalities are related to afterload increase. HF analysis is really a new challenge of cardiac imaging, as sensitive markers of subtle systolic dysfunction.

Abstract
Abstract
Background
Indigenous Australians have disproportionately poorer health outcomes than their non-Indigenous counterparts. Preventable chronic diseases, such as cardiovascular disease, are primary factors that contribute to their lower life expectancy. Health risk behaviors such as smoking, physical inactivity, poor nutrition and obesity largely contribute to the enduring health divide. Therefore, the aim of this qualitative review was to synthesize the best available evidence on the perceptions of Indigenous Australians towards cardiovascular primary prevention programs.
Methods
A search using MEDLINE, CINAHL, EMBASE, Google Scholar, MedNar, ProQuest and Index to Theses for published and unpublished studies was conducted in January 2020. The methodological quality of the included studies was assessed by two reviewers using the Joanna Briggs Institute (JBI) critical appraisal tool. Meta-aggregation was conducted in accordance with JBI methodology.
Results
Eleven studies involving 249 participants were included. Three synthesized findings were developed 1) External factors can affect participants' experiences of prevention programs. Support from family motivates participation and behavioral change. Support from health professionals that is free from judgment facilitates participation; 2) The complexities of an individual's life influence Indigenous Australian's experiences and participation in prevention programs and health risk behavioral change; 3) A personal desire to change behaviors and participate in prevention programs requires development of knowledge on healthy lifestyles, creation of new social norms and overcoming internal struggles.
Conclusions
Indigenous Australians participation in primary prevention for cardiovascular risk factors and adoption of a healthy lifestyle are influenced by social support, social determinants and personal desire. Future programs need to tackle structural drivers and create a supportive environment to assist in behavior change.
Key messages
Social determinants affect Indigenous Australians experiences and participation in prevention programs for behaviour change. Prevention programs must create a supportive environment with the inclusion of family.

Abstract
Prostate-specific membrane antigen (PSMA)-ligand PET/CT is performed on patients with prostate cancer to stage the disease initially or to identify sites of recurrence after definitive therapy. On the basis of clinical results, 18F-PSMA-1007 is a promising PSMA PET tracer, but detailed histologic confirmation has been lacking. Methods: Ninety-six patients with prostate cancer underwent 18F-PSMA-1007 PET/CT followed by either radical prostatectomy with lymphadenectomy or salvage lymphadenectomy. The histologic findings of PSMA PET-positive nodes were analyzed retrospectively. A lesion-based and patient-based analysis was performed comparing all positive lesions and only lesions larger than 3 mm on histopathology. Results: Of the patients, 90.6% received 18F-PSMA-1007 PET/CT for staging before the primary treatment, whereas 9.4% underwent imaging for biochemical recurrence. In 34.4% of the cohort, positive lymph nodes were present on imaging. In total, 1,746 lymph nodes were dissected in 96 patients. 18F-PSMA-1007 PET had a lesion-based sensitivity of 81.7%, a specificity of 99.6%, a positive predictive value of 92.4%, and a negative predictive value of 98.9% for detecting positive lymph nodes larger than 3 mm. In the analysis of all malignant nodes regardless of size, the overall sensitivity, specificity, positive predictive value, and negative predictive value on lesion-based analysis were 71.2%, 99.5%, 91.3%, and 97.9%, respectively. The patient-based analysis showed a sensitivity of 85.9% and a specificity of 99.5% for lymph nodes larger than 3 mm. Conclusion: 18F-PSMA-1007 PET/CT reliably detects malignant lymph nodes and has an exceptional specificity of more than 99% for nodal metastases.

Abstract
IntroductionPerceived and anticipated stigma is relevant issues in patients with schizophrenia. Stigma has negative consequences both in quality of life and in the course of illness.ObjectivesTo analyze the degree of perceived and anticipated stigma and discrimination in patients with schizophrenia and their relationship with clinical and socio-demographic variables.MethodsA cross-sectional study was carried out in a sample of 100 patients with diagnosis of schizophrenia, 18 or more years old, clinically stabilized, without axis I DSM-IV comorbidity. Patients received treatment in the outpatient services of a catchment area in Madrid. Perceived and anticipated discrimination was evaluated trough the DISC-12 (Discrimination and Stigma scale). Other study variables were: socio-demographic characteristics, symptoms of depression (Calgary Scale) and functionality degree measured by Global Assessment of Function (GAF).ResultsThe presence of symptoms of depression evaluated by the Calgary Scale and low degree of functionality measured by GAF are associated with greater feelings of discrimination and stigma, especially in the sub-scales of experienced and anticipated discrimination of the DISC 12. Anticipated stigma is higher in men than in women while the rest sub scales of the DISC-12 do not correlate with gender or other sociodemographic variables.ConclusionsPreventive strategies to avoid the stigma in schizophrenia should consider some characteristics associated with disease, especially the degree of functionality and presence of depressive symptoms.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Abstract
Introduction
Reports have shown increased risk of atrial fibrillation (AF) in athletes. Vascular cell adhesion molecule-1 (VCAM1) is associated with new onset AF in general population. VCAM1 and its relation with left atrial (LA) remodeling have not been investigated in athletes.
Purpose
To study VCAM1 and LA remodeling in marathon runners.
Methods
Study of 36 male marathon runners in the training period previous to race (42 km) and 18 sedentary controls with no risk factors. Athletes were divided in two groups according to highest training intensity reached (group 1, >100 km/week; group 2, 50–100 km/week). Previous to race in all subjects, VCAM1 serum levels were measured by ELISA and an echocardiogram was performed. In athletes, VCAM1 was measured immediately post-race. Wilcoxon and Spearman were used.
Results
See table. Group 1 showed a significant increment in VCAM1 post-race (651±350 to 905±373 ng/mL; p=0.002) as compared to group 2 with no increment (533±133 to 651±138 ng/mL; p=0.117). In athletes, a moderate correlation between LA volume and VCAM1 was found (rho: 0.483; p=0.007).
Baseline characteristics Group 1 (n=18) Group 2 (n=18) Controls (n=18) p value Age (years) 37±6 38±5 36±4 0.373 Heart rate (bpm) 53±8 57±7 69±6 * 0.001 Body surface area (m2) 1.8±0.1 1.8±0.1 1.9±0.1 0.075 LV diastolic diameter (mm) 49±5 48±5 46±4 0.404 LV systolic diameter (mm) 29±5 30±5 30±4 0.879 Septal wall (mm) 9.1±1.2† 8.2±1.1 8.1±0.8 0.005 Posterior wall (mm) 9.3±2.1† 8.5±1.2 7.6±0.8 0.001 Ejection fraction (%) 55±3 55±6 57±4 0.110 LV mass index (g/m2) 106±27† 78±18 58±11 0.001 LA volume (mL/m2) 42±8† 30±11 25±9 0.001 E wave (cm/sec) 78±13 84±12 77±15 0.217 A wave (cm/sec) 50±12 53±10 48±16 0.438 DT (msec) 233±65 229±65 221±66 0.184 VCAM1 (ng/mL) 651±350† 533±133 440±98 0.022 Mean ± SD. *p<0.05 vs group 1 and 2 post Kruskall-Wallis; †p<0.05 vs other groups post Kruskall-Wallis. LV, left ventricle; LA, left atrium; DT, deceleration time.
Conclusions
Most trained athletes had increased levels of VCAM1 as compared to controls and less trained athletes. They also showed an increment post-effort. VCAM1 is related to LA remodeling in athletes. VCAM1 could be a potential biomarker of AF in athletes which should be confirmed.

Abstract
OBJECTIVE Glucocorticoid excess is one of the most important causes of bone disorders. Bone marrow fat (BMF) has been identified as a l new mediator of bone metabolism. Cushing syndrome (CS), is a main regulator of adipose tissue distribution but its impact on BMF is unknown. The objective of the study was to evaluate the effect of chronic hypercortisolism on BMF. DESIGN This was a cross-sectional study. Seventeen active and seventeen cured ACTH-dependent CS patients along with seventeen controls (matched with the active group for age and sex) were included. METHODS the BMF content of the femoral neck and L3 vertebrae were measured by 1H-MRS on a 3-Tesla wide-bore magnet. BMD was evaluated in patients using dual-energy X-ray absorptiometry. RESULTS Active CS patients had higher BMF content both in the femur (82.5±2.6%) and vertebrae (70.1±5.1%) compared to the controls (70.8±3.6%, p=0.013 and 49.0±3.7% p=0.005, respectively). In cured CS patients (average remission time of 43 months), BMF content was not different from controls at both sites (72.3±2.9% (femur) and 46.7%±5.3% (L3)). BMF content was positively correlated with age, fasting plasma glucose, HbA1c, triglycerides and visceral adipose tissue in the whole cohort and negatively correlated with BMD values in the CS patients . CONCLUSIONS Accumulation of BMF is induced by hypercortisolism. In remission patients BMF reached values of controls. Further studies are needed to determine whether this increase in marrow adiposity in CS is associated with bone loss.

Abstract
It is well known that the aminoglycoside antibiotic gentamicin is capable of causing damage to kidney cells. Given the known involvement of Ca2+ in the nephrotoxic action of gentamicin, the purpose of this study was to establish a relationship between the concentration of intracellular Ca2+ ([Ca2+]i) and cellular cytotoxicity using MDCK-C11 cells, a clone that has several properties that resemble those of intercalated cells of the distal nephron. Changes in [Ca2+]i was determined using fluorescence microscopy. Cell viability was evaluated by the neutral red method, and cell cytotoxicity by the MTT method. The [Ca2+]i gradually increased when cells were exposed to 0.1 mM gentamicin for 10, 20, and 30 min. The presence of extracellular Ca2+ was found to be necessary to stimulate the increase in [Ca2+]i induced by gentamicin, since this stimulus disappeared by using 1.8 mM EGTA (a Ca2+ chelator). Morphological changes were observed with scanning electron microscopy in epithelial cells exposed to the antibiotic. Furthermore, with the MTT method, a decrease in metabolic activity induced by gentamicin was observed, which indicates a cytotoxic effect. In conclusion, gentamicin was able to alter [Ca2+]i, change the morphology of MDCK-C11 cells, and promote cytotoxicity.

Abstract
AIMS To identify (a) determinants of glycated haemoglobin (HbA1c) at 18 and 30 months following transition in young people with Type 1 diabetes mellitus (T1DM) to a youth-specific diabetes service; and to (b) evaluate the impact of the service on acute admissions with diabetic ketoacidosis (DKA) over a 14-year period. METHODS An audit of records of youth with T1DM referred from paediatric services to the multidisciplinary transition service at Westmead Hospital, from 2001 to 2012, and followed-up to 2014. RESULTS Data from 439 adolescents and young adults (Median age: 18) were analysed. The recommended standard of glycaemic control, HbA1c < 7.5% (58 mmol/mol), was achieved by 23% at baseline, 22% at 18-months, and 20% at 30-month. After adjusting for lag time (>3 months) and diabetes duration (>7 years), glycaemic control at first visit predicted subsequent glycaemic control at 18-month and 30-month follow-up. From 2001 to 2014, only 8.6% were lost to follow-up; admissions and readmissions for DKA reduced from 72% (32/47) to 4% (14/340) (p < 0.001). Furthermore, mean length of stay (LOS) significantly decreased from 6.56 to 2.36 days (p < 0.001). CONCLUSIONS Continuing engagement with the multidisciplinary transition service prevented deterioration in HbA1c following transition. Age-appropriate education and regular follow-up prevents DKA admissions and significantly reduced admission LOS.

Abstract
Background The aim of this study was to evaluate the pepsinogen C expression in malignant cutaneous melanomas and analyze its possible relationship to clinical and pathological parameters. Pepsinogen C is an aspartyl proteinase primarily involved in the digestion of proteins in the stomach and represents one of the main androgen-inducible proteins in breast cancer cells. Method Tumoral pepsinogen C expression was retrospectively analyzed in 35 paraffin-embedded tissues from patients with primary malignant cutaneous melanoma and in 10 samples from 10 benign lesions (4 dermal melanocytic nevi, 4 compound melanocytic nevi and 2 dysplastic melanocytic nevi), using immunohistochemical methods. Results The benign lesions were consistently negative for pepsinogen C, whereas 20 of the 35 malignant melanomas (57%) showed positive immunostaining for pepsinogen C. The percentage of pepsinogen C-positive tumors was significantly higher in men than in women (p=0.01) and in epithelioid melanomas than in fusocellular or mixed type melanomas (p=0.003). In addition, the percentage of pepsinogen-C positive tumors was positively and significantly correlated with lesion thickness (p=0.003), Clark's level of invasion (p=0.028) and tumor stage (p<0.001). Conclusion Pepsinogen C could be a new prognosticator of unfavorable outcome in cutaneous malignant melanoma.

Abstract
November 11, 2016/65(44);1234-1237. What is already known about this topic? Candida auris is an emerging pathogenic fungus that has been reported from at least a dozen countries on four continents during 2009-2015. The organism is difficult to identify using traditional biochemical methods, some isolates have been found to be resistant to all three major classes of antifungal medications, and C. auris has caused health care-associated outbreaks. What is added by this report? This is the first description of C. auris cases in the United States. C. auris appears to have emerged in the United States only in the last few years, and U.S. isolates are related to isolates from South America and South Asia. Evidence from U.S. case investigations suggests likely transmission of the organism occurred in health care settings. What are the implications for public health practice? It is important that U.S. laboratories accurately identify C. auris and for health care facilities to implement recommended infection control practices to prevent the spread of C. auris. Local and state health departments and CDC should be notified of possible cases of C. auris and of isolates of C. haemulonii and Candida spp. that cannot be identified after routine testing.
