Background: The mental health of first-generation college students has received much attention from researchers. The dual-factor model of mental health emphasizes the integration of psychopathology and well-being to achieve a comprehensive assessment of mental health. Previous research has focused on the psychopathology and well-being of first-generation college students in isolation while ignoring the overall mental health development. Aim: This study aims to identify the mental health profiles of first-generation college freshmen (indexed by symptoms of psychopathology and well-being) using a person-centered approach, and examine direct and interactive associations of proactive personality and university environment with mental health profiles. Method: This study included 557 first-generation college freshmen recruited from universities in China. Participants completed measures assessing proactive personality, university environment, mental health continuum, and depression, anxiety, and stress. Latent profile analysis, multinomial logistic regression, and simple slope analyses were used to investigate these relationships. Results: The results revealed four mental health profiles, namely flourishing mental health, moderate mental health, content-dominated but symptoms, and symptoms-dominated but content. A multinomial logistic regression analysis revealed that first-generation college freshmen with higher proactive personality and university environment were more inclined to fall into the flourishing mental health profile compared to other sub-optimal mental health profiles. The interaction term between proactive personality and university environment was significant. Specifically, compared to proactive first-generation college freshmen in high levels of university environment, those in low levels of university environment were more inclined to be categorized into the flourishing mental health profile rather than the symptoms-dominated but content profile. Conclusion: These results underscore the diverse nature of mental health changes in first-generation college freshmen, underscoring the need for tailored prevention strategies.

Background: The cementoma is a common disease of the dental root apex, which generally occurs in the maxilla and the mandible, but the cementoma occurring in the long bone is rare. Moreover, the incidence of cementoma in the calcaneus is extremely infrequent.Case Presentation: The present study reports an unusual case of a 19-year-old girl, who complained of pain in the left heel. Subsequent radiographs and computed tomography (CT) were used in the diagnosis. The imaging features of the lesion included a radiopaque matrix and radiolucent tissue, particularly an arc-shaped fat band. An excisional biopsy was performed. Histopathological examination confirmed the diagnosis of cementoma in the calcaneus. After the operation, the patient was followed up without recurrence.Conclusions: Imaging examination plays an important role in the differential diagnosis of cementoma of the calcaneus.

Background: Percutaneous lag screw fixation is an alternative treatment for non-displaced or minimally displaced posterior column fractures. This study aims to explore new fluoroscopic views of the acetabulum for safe percutaneous insertion of posterior column lag screws.Methods: Axial computed tomography (CT) scans were taken of sixteen embalmed adult cadavers. The axial CT images at the level of the middle height of the acetabulum were selected. The angle (angle α) between the posterior cortex of the posterior column (PCPC) and the line intersecting the axial plane and the coronal plane, and the angle (angle β) between the medial wall and the line intersecting the axial plane and the sagittal plane were identified and measured. Tangential views of the PCPC and medial wall were obtained by referencing the measured angles. A lag screw was inserted into the posterior columns of the sixteen pelvic specimens under fluoroscopic guidance using an iliac oblique view and the two tangential views. CT scans were performed to evaluate the lag screw position. Axial CT images of 52 volunteers were obtained and the angles α and β were measured following the same methods used for the cadaveric specimens.Results: The angles α and β for the specimens were 29.3 ± 2.8.1 and 8.1 ± 1.4 degrees, respectively. On the tangential view of the PCPC, the posterior cortex appears as a nearly straight line between the lesser and greater sciatic notches. On the tangential view of the medial wall, the medial wall appears as a distinct straight line. Using these radiographic images, the lag screws were inserted into the posterior columns of bony pelvic specimens. Screw placement was confirmed by CT, and found to be fully intraosseous in all cases without any cortical breaches. The angles α and β were 30.4 ± 4.1 and 9.2 ± 1.9 degrees for male volunteers and 28.5 ± 3.7 and 7.7 ± 1.8 degrees for female volunteers, significant difference in these angles between cadaveric specimens and human volunteers.Conclusion: The tangential views of both the PCPC and medial wall can be obtained following the aforementioned methods The oblique iliac view and the two tangential views enable safe insertion of posterior column lag screws.
