Research progress on the burden of respiratory syncytial virus infection in the elderly / 中华预防医学杂志

Human Respiratory Syncytial Virus (HRSV) is a serious threat to the population health. The elderly are one of the susceptible populations. The prevalence of HRSV in the elderly is generally higher than that in other age groups except children, which has gradually attracted attention in recent years. This paper reviewed the prevalence, common complications and major complications of HRSV in the elderly, briefly expounded the economic burden of HRSV infection, and proposed that attention should be paid to the disease burden of the elderly after HRSV infection, timely treat common complications, so as to reduce the occurrence of adverse survival outcomes and provide scientific evidence for the prevention and control of HRSV infection in the elderly.

Application of 3D Printing Combined with S-ROM Total Hip Arthroplasty in the Treatment of Adult Crowe Ⅳ DDH / 昆明医科大学学报

Objective To investigate the application of 3D printing combined with S-ROM total hip arthroplasty in the treatment of adult Crowe IV DDH. Methods Between September 2014 and June 2017, 10 patients of adult Crowe IV DDH were selected and divided into 3D group (5 cases) and non-3D group (5 cases) . There were 4 males and 6 females with an average age of 43.6 years (range,27-63years) . Harris scores were recorded in both groups before the operation, and in the group 3D, patients underwent spiral CT scanning to make the hip 3D models. According to the hip 3D models, the sizes of prosthesis and operation schemeswere estimated before the operation ,and the surgery simulation was performed. Then the S-ROM prosthesis was used for total hip arthroplasty. The actual situation of hip joint, the size of prosthesis,time of operation and blood loss were recorded.Harris Score at 1 week post-operationwere recorded again. All patients were followed up related postoperative complications for at least 2 weeks.Results The 3D printing models coordinated with the actual sizes of the hips in the3D group.The time of operation and blood loss were less than the non-3D group. Higher Harris score was observed at 1 week post-operation in the 3D group,compared to non-3D printing group.The follow-up showed that the motion of the hips was improved obviously. Conclusion The Application of 3D Printing combined with S-ROM total hip arthroplasty in the treatment of adult crowe IV DDH can improve efficiency and accuracy of the operation, shorten time of operation , reduce operative blood loss and rate of complications.
