This is the accepted version of the paper.This version of the publication may differ from the final published version. Arabia, and to some extent in Turkey, reduced ORs were observed for Austria, China, Italy, Japan and the USA. Elevated ORs for psychological distress were seen in Japan, Jordan, Palestine, Saudi Arabia, Tunisia and Turkey but reduced ORs were noted in Austria, China, Iran, Italy and the USA. Psychological distress was strongly associated with reports of suicide ideation and attempts. Suicide ideation, suicide attempt and psychological distress are common in university students but their rates vary depending on the sociocultural context. Permanent repository linkDue attention should be devoted to the mental health needs of young adults enrolled in higher educational institutions and more cross-cultural research is warranted to better understand the etiology of the observed intersocietal variations in suicidal behavior and psychological distress.

Portal vein tumor thrombus (PVTT) is very common, and it plays a major role in the prognosis and clinical staging of hepatocellular carcinoma (HCC). We have published the first version of the Consensus in 2016. Over the past several years, many new evidences for the treatment of PVTT become available especially for the advent of new targeted drugs which have further improved the prognosis of PVTT. So, the Chinese Association of Liver Cancer revised the 2016 version of consensus to adapt to the development of PVTT treatment. Future treatment strategies for HCC with PVTT in China would depend on new evidences from more future clinical trials.

Poly(ethylene glycol) (PEG) cryogels with aligned porous structures were prepared by unidirectional freezing and subsequently cryopolymerization. The aqueous reaction precursor of poly(ethylene glycol) diacrylate (PEGDA) and the initiator was first unidirectionally frozen using liquid nitrogen or other cooling agents such as frozen ethyl alcohol and frozen acetic ether, followed by radical polymerization at subzero temperature. The morphology of the obtained cryogels was observed by scanning electron microscopy (SEM) and confocal laser scanning microscope (CLSM). The pore structure of the obtained cryogels was the replica of the unidirectional ice crystals formed during the unidirectional freezing. Microtubular pores aligned along the freezing direction were observed in both dry and swollen states. The obtained cryogels showed anisotropic compressive strength according to the pore directions. The effect of the PEGDA molecular weight and the freezing temperature on morphology of the orientationstructured cryogels were also studied. The pore diameter could be adjusted from 10 to 50 mm.

Hepatocellular carcinoma (HCC) is the sixth-most common cancer and the third leading cause of cancer-related death in the world. However, 40-70% patients eventually suffer from postoperative recurrence within 5 years. HCC recurrence after surgery severely affects prognosis of the patients. Nevertheless, there is an opportunity to improve patients' prognosis if doctors and researchers can recognize the importance of a standardized perioperative management and study it in clinical and pre-clinical settings. Hence, based on our own experience and published studies from other researchers, we develop this consensus regarding multidisciplinary management of locally recurrent and metastatic hepatocellular carcinoma after resection. This consensus consists of the entire course of recurrent hepatocellular carcinoma (RHCC) management, including prediction of recurrence, prevention, diagnosis, treatment and surveillance of RHCC. Consensus recommendations are presented with grades of evidences (
