Most of the biomedical materials printed using 3D bioprinting are static and are unable to alter/transform with dynamic changes in the internal environment of the body. The emergence of four-dimensional (4D) printing addresses this problem. By preprogramming dynamic polymer materials and their nanocomposites, 4D printing is able to produce the desired shapes or transform functions under specific conditions or stimuli to better adapt to the surrounding environment. In this review, the current and potential applications of 4D-printed materials are introduced in different aspects of the biomedical field, e.g., tissue engineering, drug delivery, and sensors. In addition, the existing limitations and possible solutions are discussed. Finally, the current limitations of 4D-printed materials along with their future perspective are presented to provide a basis for future research.

Background The COVID‐19 pandemic has powerfully shaped people’s lives. The current work investigated the emotional and behavioral reactions people experience in response to COVID‐19 through their internet searches. We hypothesised that when the prevalence rates of COVID‐19 increase, people would experience more fear, which in turn would predict more searches for protective behaviors, health‐related knowledge, and panic buying. Methods Prevalence rates of COVID‐19 in the United States, the United Kingdom, Canada, and Australia were used as predictors. Fear‐related emotions, protective behaviors, seeking health‐related knowledge, and panic buying were measured using internet search volumes in Google Trends. Results We found that increased prevalence rates of COVID‐19 were associated with more searches for protective behaviors, health knowledge, and panic buying. This pattern was consistent across four countries, the United States, the United Kingdom, Canada, and Australia. Fear‐related emotions explained the associations between COVID‐19 and the content of their internet searches. Conclusions Findings suggest that exposure to COVID‐19 prevalence and fear‐related emotions may motivate people to search for relevant health‐related information so as to protect themselves from the pandemic.

Objective: To compare and analyze the clinical outcomes of the proximal humeral internal locking system (PHILOS) alone and the PHILOS combined with fibular allograft in the treatment of Neer three-and four-part proximal humerus fractures (PHF) in the elderly. , a total of 42 elderly patients with Neer three-or four-part PHF admitted to our hospital were randomly divided into observation group and control group, with 21 patients in each group. The observation group was treated with the PHILOS combined with fibular allograft. The control group was treated with the PHILOS alone. Perioperative parameters and fracture classification were recorded in the two groups. Function results were assessed by Visual Analog Scale (VAS), Constant-Murley score (CMS), American Shoulder and Elbow Surgeons (ASES) score, and the Disability of Arm-Shoulder-Hand (DASH) score. Radiological results were evaluated using the neck-shaft angle (NSA) and humeral head height (HHH), and complications were also recorded in each group.Results: There were no significant differences between the two groups in terms of preoperative status, age, gender, cause of trauma, fracture site, and fracture classification. The average follow-up time was 12 months. At the last follow-up, the VAS and DASH observation groups were lower than the control group, and there was significant difference between the two groups (P < 0.05). The CMS and ASES were higher in the observation group than the control group, and there was significant difference between the two groups (P < 0.05). The mean difference in the NSA and HHH were lower in the observation group than the control group, and there was a significant difference between the two groups (P < 0.05). There was one postoperative complication in the observation group, which was humeral head avascular necrosis (AVN). There were seven postoperative complications in the control group, including three cases of humeral head collapse and three cases of screw cutout and one case of humeral head AVN. The incidence of postoperative complications in the observation group was significantly lower than the control group (P < 0.05), there was a significant difference between the two groups.Conclusions: For Neer three-or four-part PHF in the elderly patients, PHILOS fixation with fibular allograft shows satisfactory short-term results with respect to humeral head support and maintenance of reduction, and may reduce the incidence of complications associated with fixation using a PHILOS alone.
