As an alternative experimental model to replace further in vivo investigations of ontogenetically important processes, we initiated the first approach towards a long-lasting primary cell culture from whole pikeperch embryos. The present study provides a set of possible biomarkers to support the monitoring of pikeperch farming and provides a first basis for the establishment of a suitable cell model of this emerging aquaculture species.Perceptual information about unfolding events is important for guiding decisions about when and how to move in real-world action situations. As an exemplary case, road-crossing is a perceptual-motor task where age has been shown to be a strong predictor of risk due to errors in action-based decisions. The present study investigated age differences between three age groups (Children 10-12 years old; Adults 19-39 years old; Older Adults 65 + year olds) in the use of perceptual information for selection, timing, and control of action when crossing a two-way street in an immersive, interactive virtual reality environment. Adults and children selected gaps to cross that were consistent with the use of a time-based information variable (tau), whereas older adults tuned less into the time-based variable (tau) to guide road-crossing decisions. For action initiation and control, children and adults also showed a strong ability to precisely time their entry with respect to the lead vehicle maximising the available time to cross and coordinating walking movements with the tail vehicle to ensure they were not on a collision course. In contrast, older adults delayed action initiation and showed difficulty coordinating self-movement with the approaching vehicle. This study and its results tie together age-based differences in the three components of action decision-making (selection, timing and control) within a unified framework based on perceptual information. The implications of these age-related differences in action decisions and crossing behaviours are discussed in the context of road safety.
Immune checkpoint inhibitors (ICIs) represent a breakthrough in the management of many hard-to-treat cancers over the past decade with demonstrable improvement in survival outcomes. We reviewed the state of the art of ICIs in neuroendocrine neoplasms (NENs). While ICIs have become part of the standard of care for the management of small cell lung cancer (SCLC), their role is still unclear in the management of extra-pulmonary (EP) poorly differentiated neuroendocrine carcinomas (NECs) as well as in the management of well-differentiated neuroendocrine tumors (NETs). Conflicting results derived from the various studies in NETs and EP NECs therefore for specific settings, such as the lung NETs, or therapeutic regimen, e.g., combo vs single agent, for ICIs benefit. Therefore, at the moment, no ICIs approach is justified for NETs and EP NECs in clinical practice. Future investigations should be designed with the aim to overcome the several limitations of the current trials, e.g., lacking of a central pathology refor specific settings, such as the lung NETs, or therapeutic regimen, e.g., combo vs single agent, for ICIs benefit. Therefore, at the moment, no ICIs approach is justified for NETs and EP NECs in clinical practice. Future investigations should be designed with the aim to overcome the several limitations of the current trials, e.g., lacking of a central pathology review or heterogeneity of the cohorts, in order to reduce the risk of biases. Future trials combining ICIs with other biological agents are welcome. This review aims to provide a comprehensive overview of the biological rationale and evolving clinical applications of the use of ICIs in the management of NENs (both well-differentiated and poorly differentiated groups).The coronavirus has challenged all medical systems worldwide. Herein both waves of COVID-19 (coronavirus disease 2019) in spring and autumn 2020 differ principally. Whereas Europe was hit by the first wave more or less unprepared, which was aggravated by the high virulence of COVID-19, the second wave is characterized by a much higher contagiosity of the virus with very high incidences. On the other hand the virus has attenuated, which is reflected by the significantly lower incidence-related mortality rate. However, the overall increasing number of infected patients represents again a great challenge for the medical management of the disease. France and Spain are doing better in comparison to Germany and Italy this time. The absolute number of deaths per week is higher than during the peak of the first wave. However, urologists in these countries have also experienced greater restrictions in their activities in the second shutdown than in Germany, where there is only a reduction of beds to between 75 and 90%. Mostly all levels are operated. Of importance for Germany, however, is the plateau on a high level for several weeks probably due to the reduced efficacy of a light lock-down. This finally resulted in a total lock-down in mid-December 2020. Subsequently in Germany some hospitals are also reaching their limits with similar consequences for the departments of urology facing a 50% reduction of beds and operating only level III and IV indications. Nevertheless, the management of urologic patients during the COVID-19 pandemic is carried out in Europa on a high standard. Therefor the risk of secondary harm to our patients is expected to be rather minimal in the long run.
Anti-Ro/SSA and anti-La/SSB antibodies are associated with neonatal lupus and congenital heart block. Controversial results regarding perinatal outcomes are found and less is known about aneuploidy screening. The hypothesis is that the presence of anti-Ro and/or anti-La antibodies influences the levels of PAPP-A and ß-HCG, thus interfering in the calculation of risk of aneuploidies.
Fifty-five anti-Ro/SSA positive pregnant women were included. The demographic characteristics and laboratory variables were studied. Data concerning chromosomopaties screening were also recorded.
PAPP-A and β-HCG levels were calculated (as well as NT and CRL) and compared with a healthy cohort of 12971 pregnant women. PAPP-A levels in mg/mL were lower significatively. In anti-La/SS-B cohort, significant differences were found in PAPP-A in mg/mL and in MoM. Combined risks for Down syndrome (DS) in both groups were higher but the differences were due to age.
Serum levels of PAPP-A were significative lower but not confirmed wicative lower but not confirmed when adjusted to MoM. This will have to be confirmed in studies with a larger number of patients and to check whether there is an impact in the calculation of DS risk or not. They could represent a group of pregnant women with significantly a higher risk of adverse perinatal outcome. Key Points • Pregnant patients with anti-Ro/SS-A ant/or anti-La/SS-B antibodies have low PAPP-A levels compared with pregnant women without antibodies. • PAPP-A levels are used in obstetrics for aneuploidies screening in the first trimester, so in these patients, there could be more false positive screening. • In these findings are verified in trials with a larger number of patients, a correction variable would have to be applied for the aneuploidies screening calculation. • Also, low PAPP-A levels are correlated with poor placentation, that is to say, more risk of miscarriages, small fetus for gestational age, and preeclampsia. This is another topic to take into consideration in this population.
The National Health Service Diabetes Prevention Programme (NHS-DPP) is a behavioural intervention for people identified as high risk for developing type 2 diabetes that has been rolled out across England. The present study evaluates whether the four commercial providers of the NHS-DPP train staff to deliver behaviour change technique (BCT) content with fidelity to intervention plans.
One set of mandatory training courses across the four NHS-DPP providers (seven courses across 13days) was audio-recorded, and all additional training materials used were collected. Recordings and training materials were coded for BCT content using the BCT Taxonomy v1. BCTs and depth of training (e.g. instruction, demonstration, practice) of BCT content was checked against providers' intervention plans.
Ten trainers and 78 trainees were observed, and 12 documents examined. The number of unique BCTs in audio recordings and associated training materials ranged from 19 to 44 across providers, and staff were trained in 53 unique BCTs across the whole NHS-DPP. Staff were trained in 66% of BCTs that were in intervention plans, though two providers trained staff in approximately half of BCTs to be delivered. The most common way that staff were trained in BCT delivery was through instruction. Training delivery style (e.g. experiential versus educational) varied between providers.
Observed training evidences dilution from providers' intervention plans. NHS-DPP providers should review their training to ensure staff are trained in all key intervention components, ensuring thorough training of BCTs (e.g. demonstrating and practicing how to deliver) to enhance BCT delivery.

Poor emotion regulation is associated with post-traumatic stress symptoms (PTSS). However, limited prospective research prevents any directional conclusions. No known studies have assessed emotion regulation with PTSS in American Indians, a high-risk population for poor mental health outcomes. Dyngo-4a in vivo The present prospective study explored whether emotion regulation strategies (cognitive reappraisal, expressive suppression) predicted later PTSS related to the COVID-19 global pandemic in a solely American Indian sample.
American Indian participants (N = 210; Mean (SD) age = 54.85(13.08) years, 58.7% female) completed the Emotion Regulation Questionnaire (ERQ) during Phase 1 (a few weeks before pandemic declaration) and the Impact of Event Scale-Revised (IES-R) with respect to the COVID-19 pandemic during Phase 2 (7-8weeks after pandemic declaration). Bivariate correlations and hierarchical linear regression analyses were utilized.
ERQ reappraisal was negatively associated with IES-R total scores, such that higher reappraisal predicted lower PTSS. In contrast, ERQ suppression was positively associated with IES-R total scores, such that higher suppression predicted higher PTSS.
Greater suppression and lower reappraisal predicts PTSS in response to the COVID-19 pandemic in an entirely American Indian sample, providing critical information for future interventions in a population at high-risk for mental health disparities.

A non-equilibrium bio-tissue heat transfer model coupled with thermo-mechanical effect for the explosive vaporization of melanin granule induced by laser heating was developed to investigate the temperature and thermal damage distribution using alexandrite (755 nm) and NdYAG (1064 nm) lasers with the pulse width of 10-120 ns. Cryogen spray cooling (CSC) was introduced to prevent the epidermal thermal damage due to competitive laser absorption between epidermal and dermal melanin. Thermal injury of the epidermis with temperature in the melanin zone reaching 132.3 °C was induced by alexandrite laser. The optimal pulse durations were 50 and 30 ns, and the corresponding incident laser fluence thresholds were 6.45 and 19.5 J·cm-2 for alexandrite and NdYAG laser, respectively, with the pre-cooling of R32 spray.
