The effect of massage therapy on pain after surgery: A comprehensive meta-analysis

BackgroundFindings on the usefulness of massage therapy (MT) in postoperative pain management are often inconsistent among studies.ObjectivesThis study’s aim is to conduct a meta-analysis of randomized controlled trials (RCT) to clarify the effects of massage therapy in the treatment of postoperative pain.MethodsThree databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) were searched for RCTs published from database inception through January 26, 2021. The primary outcome was pain relief. The quality of RCTs was appraised with the Cochrane Collaboration risk of bias tool. The random-effect model was used to calculate the effect sizes and standardized mean difference (SMD) with 95 % confidential intervals (CIs) as a summary effect. The heterogeneity test was conducted through I². Subgroup and sensitivity analyses were used to explore the source of heterogeneity. Possible publication bias was assessed using visual inspection of funnel plot asymmetry.ResultsThe analysis included 33 RCTs and showed that MT is effective in reducing postoperative pain (SMD, −1.32; 95 % CI, −2.01 to −0.63; p = 0.0002; I² = 98.67 %). A similar significant effect was found for both short (immediate assessment) and long terms (assessment performed 4–6 weeks after the MT). Remarkably, we found neither the duration per session nor the dose had an impact on the effect of MT and there seemed to be no difference in the effects of different MT types. In addition, MT seemed to be more effective for adults. Furthermore, MT had better analgesic effects on cesarean section and heart surgery than orthopedic surgery.LimitationsPublication bias is possible due to the inclusion of studies in English only. Additionally, the included studies were extremely heterogeneous. Double-blind research on MT is difficult to implement, and none of the included studies is double-blind. There was some heterogeneity and publication bias in the included studies. In addition, there is no uniform evaluation standard for the operation level of massage practitioners, which may lead to research implementation bias.ConclusionsMT is effective in reducing postoperative pain in both short and long terms.     

Trends in using mesenchymal stromal/stem cells (MSCs) in treating corneal diseases

Since their inception in the 1960s–70s, mesenchymal stem/stromal cells (MSCs) have gained interest because of their differentiation potential, anti-inflammatory effects, and immune-modulating properties. Both cell-based and cell-free MSC treatments show healing capacity in injured tissues. Cell-based treatment comprises MSCs and all secreted products, whereas cell-free treatments include only the secreted products. MSCs are therapeutically administered to many damaged organs owing to their efficacy. Specifically, the eye is a unique organ system to study the effects of MSCs, as treatment is easily applied and measured owing to its external location. The eye holds an immune-privileged status, wherein inflammation and immune responses are innately down-regulated. As excessive inflammation in the cornea often leads to fibrosis and irreversible corneal hazing, many studies have investigated the anti-inflammatory and immune-modulating capacities of MSCs. Decades of research suggest that MSCs modulate the immune response by secreting cytokines, growth factors, and extracellular matrix proteins that inhibit the infiltration of inflammatory cells following injury and promote a healing phenotype via M2 macrophage polarization. MSCs have also shown trans-differentiation potential into cornea-specific cell types during the wound healing process, such as corneal epithelial, stromal, or endothelial cells. This review discusses recent investigations of MSC treatment in the cornea, focusing on therapeutic efficacy, mechanisms, and future directions.     

子野个数限值对宫颈癌固定野调强放疗计划的影响

目的:分析子野个数限值对宫颈癌固定野调强放疗（fixed-field intensity-modulated radiotherapy,ff-IMRT）计划的影响，寻求最优的子野个数限值。方法:选取10例接受ff-IMRT的宫颈癌患者，基于Monaco 5.11.03计划系统，以45 Gy/25 f处方剂量分别对同一患者设计8种ff-IMRT计划（ff-IMRT计划依据子野个数限值命名，子野个数限值分别为40、60、70、80、100、120、130、150），采用SPSS 20.0软件比较除plan100之外7个ff-IMRT计划与plan100剂量学参数、优化时间和治疗参数的差异。结果:8种ff-IMRT计划归一化后，plan40和plan60的D2%、Dmin、CI和HI均劣于plan100（P＜0.05）。8种ff-IMRT计划均能较好保护危及器官（organ at risk,OAR）和正常组织。plan40小肠V45;plan40和plan60小肠D2cc，直肠、膀胱V45、D40%，两侧股骨头V40和正常组织 V35、V40均高于plan100（P＜0.05）。plan40和plan60优化时间、治疗参数均优于plan100（P＜0.05）；plan120、plan130和plan150子野面积、子野个数（51~150 cm2和＞150 cm2）和出束时间均劣于plan100（P＜0.05）。结论:子野个数限值为70~100时，ff-IMRT计划能兼顾剂量学参数满足临床要求、优化时间和治疗参数最优化，建议在设计宫颈癌ff-IMRT计划时在该范围内设置子野个数限值。     

Epstein–Barr-virus-associated hepatitis with aplastic anemia: A case report

ABSTRACT BACKGROUND Hepatitis-associated aplastic anemia (HAAA) is a rare condition. Patients with HAAA usually present with acute hepatitis, jaundice and significantly increased transaminase. After 1–2 mo, hepatitis gradually improves, but progressive hemocytopenia, bone marrow hematopoietic failure, and severe or extremely severe aplastic anemia are manifest. Most cases of HAAA are fulminant and usually lethal if left untreated. The literature on Epstein–Barr virus (EBV)-associated HAAA is sparse. CASE SUMMARY We report a 30-year-old man who was admitted to our hospital because of pale yellow urine and skin with a simultaneous decrease in peripheral blood ternary cells. We made a diagnosis of EBV-associated HAAA. The treatment strategy for this patient included eltrombopag, an immunosuppressive regimen of rabbit anti-human thymocyte immunoglobulin, cyclosporine, and supportive care. The patient was discharged in normal physical condition after five months. A hemogram performed on follow-up revealed that he had achieved a complete response. CONCLUSION Eltrombopag plus anti-thymocyte globubin and cyclosporine may be a therapeutic option for EBV-associated HAAA.Larger studies are warranted to confirm.     

Electroconvulsive therapy plays an irreplaceable role in treatment of major depressive disorder

Major depressive disorder is a serious and common neuropsychiatric disorder that affects more than 350 million people worldwide. Electroconvulsive therapy is the oldest and most effective treatment available for the treatment of severe major depressive disorder. Electroconvulsive therapy modifies structural network changes in patients with major depressive disorder and schizophrenia. And it can also affect neuroinflammatory responses and may have neuroprotective effects. Electroconvulsive therapy plays an irreplaceable role in the treatment of major depressive disorder.
