D-AP, and the higher severity of AP in COVID patients could partially contribute to this increment.

Acute pancreatitis as presenting form of COVID-19 in the ED is unusual ( less then 1‰ cases). Some clinically distinctive characteristics are present compared to the remaining COVID patients and can help to identify this unusual manifestation. In-hospital mortality of COVID-AP does not differ from COVID-non-AP but is higher than non-COVID-AP, and the higher severity of AP in COVID patients could partially contribute to this increment.

The aim of the study was to determine the value of the number of patient encounters and tooth extractions on the competence of final-year Bachelor of Dental Surgery (BDS) students.

Following ethics approval, the study employed purposive sampling to enrol final-year BDS students and assess their competence longitudinally over a full academic year. Students were assessed periodically on four separate occasions after they had gained experience in performing 15, 40, 70 and 100 patient encounters involving tooth extractions.

There were 177 students with complete profiles completing the tooth extraction assessments including 31 males (18%) and 146 females (82%). The age range of participants was 22 to 24years (mean=21.92; median=22). The total number of assessment data points available for the four assessments was 1062. A chi-squared test was carried out to test the hypothesis that competence in tooth extraction increases with increasing exposure to patients. Students in Group 100 were most likely to pass thehow a positive relationship between the number of tooth extractions performed and competence of final-year dental students. Over 90% students achieved competence after performing 100 patient encounters. Although competence in tooth extractions showed a linear relationship with experience of the participants in this study, the data were collected from a single cohort of students at one institution. Further multi-institution studies involving several cohorts are required to further explore the value of increased experience.

Research among adult and paediatric samples suggests that pain-related injustice appraisals contribute to adverse pain-related functioning. However, a singular focus on pain-related injustice appraisals carries the risk of underestimating the role of broader concepts of justice. This study examined the unique roles of child pain-related injustice appraisals and just-world beliefs in understanding disability and physical, emotional, social and academic functioning, as well as the mediating role of injustice appraisals in the relationship between just-world beliefs and functioning.

Participants comprised a school sample of 2,174 children (Study 1) and a clinical sample of 146 paediatric chronic pain patients (Study 2) who completed the Injustice Experience Questionnaire (IEQ), Personal and General Belief in a Just World scales (JWB-P/G), Functional Disability Inventory (FDI), Pain Catastrophizing Scale for Children (PCS-C) and Pediatric Quality of Life Inventory (PEDSQL).

For both samples, child pain-related functioning. These findings suggest that interventions may target pain-related injustice appraisals as a mechanism for change in children.

The present study adds to emerging literature on the adverse effects of child pain-related injustice appraisals in the context of pain, through showing that pain-related injustice appraisals are uniquely associated with pain-related functioning and mediate the relationship between just-world beliefs and pain-related functioning. These findings suggest that interventions may target pain-related injustice appraisals as a mechanism for change in children.

Light-sheet microscopy (LSM) is a novel imaging technology that has been used for imaging fluorescence contrast in basic life science research. In this paper, we have developed a scattering-based LSM (sLSM) for rapidly imaging the cellular morphology of fresh tissues without any exogenous fluorescent dyes.

In the sLSM device, a thin light sheet with the central wavelength of 834 nm was incident on the tissue obliquely, 45° relative to the tissue surface. The detection optics was configured to map the light sheet-illuminated area onto a two-dimensional imaging sensor. The illumination numerical aperture (NA) was set as 0.0625, and the detection NA 0.3.

The sLSM device achieved a light sheet thickness of less than 6.7 µm over 284 µm along the illumination optical axis. The detection optics of the sLSM device had a resolution of 1.8 µm. The sLSM images of the swine kidney ex vivo visualized tubules with similar sizes and shapes to those observed in histopathologic images. Protosappanin B order The swine duodenum sLSM images revealed cell nuclei and villi architecture in superficial lesions and glands in deeper regions.

The preliminary results suggest that sLSM may have the potential for rapidly examining the freshly-excised tissue ex vivo or intact tissue in vivo at microscopic resolution. Further optimization and performance evaluation of the sLSM technology will be needed in the future. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Road traffic collisions (RTC) are known to be one of the major causes of maxillofacial trauma (MFT). The road user factor is of crucial importance in the prevalence, severity, and treatment of maxillofacial injuries. The aims of the study were to determine the prevalence of maxillofacial trauma among road users, to illustrate injury patterns and to identify road users at high risk.

This historical prospective multi-center study was based on Israel's Trauma Registry between 2008-2018, which included 4829 hospitalized patients following RTC with MFT. Data were analyzed according to six road user types (vehicle driver, passenger, bicyclist, motorcyclist, pedestrian, and e-bike/scooter), maxillofacial injury location, and maxillofacial treatment.

MFT, which accounted for 5% of the hospitalized RTC injuries, was not equally distributed among road users, as bicyclists and e-bike/scooters were more prone to maxillofacial trauma (7.2% and 10.1%, respectively) than vehicle drivers (3.2%). Children (age 0-14years) comprised almost half of the cyclists, 25% of the pedestrians and 20% of the passengers.
