  • Objectives: This study reports the findings that support the efficacy of herbal medicine (HM) for premenstrual syndrome (PMS). Methods: We conducted meta-analysis of findings from randomized controlled trials (RCTs) for PMS treated with HM. The articles were published before July 2022, located using 9 databases (Pubmed, EMBASE, Cochrane Library, CINAHL, CNKI, CiNii, SCIENCE ON, KoreaMed, OASIS). Results: We observed 2,034 studies, of which 23 RCTs met our inclusion criteria. The risk of bias in the included studies was relatively unclear or high. Meta-analysis of 3 RCTs showed that HM group had a significantly higher total effective rate than the western medicine group (RR 1.20 [95% CI 1.06, 1.36, p=0.004]). Meta-analysis of 1 RCT showed that HM group had a significantly lower symptom score (MD -3.04 [95% CI -5.36, -0.72, p=0.01]), while there was no significant difference in daily record of severity of problems scale (MD -20.52 [95% CI -49.33, 8.29, p=0.16]). Conclusions: HM significantly improved PMS symptoms than general treatment and no serious adverse events were reported. However, the evidence on the effectiveness and safety of HM for PMS was not enough to provide reliable results due to the small number and low quality of included studies. We believe that rigorous RCTs will lead to more reliable evidence of the intervention.

  • Purpose: Functional dyspepsia (FD) is a chronic syndrome accompanied by repetitive digestive symptoms that appear in the upper gastrointestinal tract and are not caused by specific diseases. Psychological symptoms like anxiety, depression, insomnia, and somatization are frequently observed in FD. The purpose of this study was to review the effect of herbal medicine on the psychological symptoms that accompany FD. Methods: Database search (PubMed, EMBASE, KISS, Kmbase, KoreanMed, NDSL, OASIS, CNKI) was performed on February 24, 2021; a total of 1825 studies were searched. After the screening, 22 studies were included. Results: The studies were assessed by Cochrane RoB 2 and sorted into a table according to psychological symptoms. Meta-analysis was performed to estimate the effect of herbal medicine. Twenty of the twenty-two studies reported that herbal medicine was significantly more effective than the control group. Only three of the studies did not have a high risk of bias. Conclusion: Herbal medicine was significantly effective with or without Western medicine and had fewer adverse effects. Severe adverse effect was not reported. Psychological symptoms in FD affect onset and duration of FD, and some FD patients want to be treated for their anxiety before other symptoms. Reliable information about treatment for the psychological symptoms of FD is lacking. We reviewed the effect of herbal medicine treatment in this study, the results of which could be selected for primary or secondary treatment for FD.

  • Objective : Although full-endoscopic lumbar interbody fusion (Endo-LIF) has been tried as the latest alternative technique to minimally invasive transforaminal lumbar interobody fusion (MIS-TLIF) since mid-2010, the evidence is still lacking. We compared the clinical outcome and safety of Endo-LIF to MIS-TLIF for lumbar degenerative disease. Methods : We systematically searched electronic databases, including PubMed, EMBASE, and Cochrane Library to find literature comparing Endo-LIF to MIS-TLIF. The results retrieved were last updated on December 11, 2020. The perioperative outcome included the operation time, blood loss, complication, and hospital stay. The clinical outcomes included Visual analog scale (VAS) of low back pain and leg pain and Oswestry disability index (ODI), and the radiological outcome included pseudoarthosis rate with 12-month minimum follow-up. Results : Four retrospective observational studies and one prospective observational study comprising 423 patients (183 Endo-LIF and 241 MIS-TLIF) were included, and the pooled data analysis revealed low heterogeneity between studies in our review. Baseline characteristics including age and sex were not different between the two groups. Operation time was significantly longer in Endo-LIF (mean difference [MD], 23.220 minutes; 95% confidence interval [CI], 10.669-35.771; p=0.001). However, Endo-LIF resulted in less perioperative blood loss (MD, -144.710 mL; 95% CI, 247.941-41.478; p=0.023). Although VAS back pain at final (MD, -0.120; p=0.586), leg pain within 2 weeks (MD, 0.005; p=0.293), VAS leg pain at final (MD, 0.099; p=0.099), ODI at final (MD, 0.141; p=0.093) were not different, VAS back pain within 2 weeks was more favorable in the Endo-LIF (MD, -1.538; 95% CI, -2.044 to -1.032; p<0.001). On the other hand, no statistically significant group difference in complication rate (relative risk [RR], 0.709; p=0.774), hospital stay (MD, -2.399; p=0.151), and pseudoarthrosis rate (RR, 1.284; p=0.736) were found. Conclusion : Relative to MIS-TLIF, immediate outcomes were favorable in Endo-LIF in terms of blood loss and immediate VAS back pain, although complication rate, mid-term clinical outcomes, and fusion rate were not different. However, the challenges for Endo-LIF include longer operation time which means a difficult learning curve and limited surgical indication which means patient selection bias. Larger-scale, well-designed study with long-term follow-up and randomized controlled trials are needed to confirm and update the results of this systematic review.

  • Objectives: Postoperative pain is one of postoperative complications in patients with solid tumor. This systematic review and meta-analysis were aimed to evaluate the efficacy of acupuncture for postoperative pain in solid tumor. Methods: We searched for randomized controlled trials (RCTs) using acupuncture for postoperative pain in adult patients with solid tumor up to September 2016. Acupuncture was defined as manual acupuncture, electroacupuncture and pharmacopuncture. The following databases were searched: PubMed, EMBASE, Cochrane Library, CNKI, CiNii, KoreaMed, Kmbase, KISS, NDSL, KISTI. The results of the studies were meta-analyzed and the risk of bias was assessed. Results: Five studies were included in this review. When acupuncture was compared with usual care, Prince-Henry pain scale score was significantly lower in acupuncture group (MD=-0.44, 95% CI: -0.62 to -0.26, P<0.001, $I^2=87%$) and 10 points pain score (including Numeric Rating Scale and Visual Analog Scale) was lower in acupuncture group but not significantly (MD=-1.00, 95% CI: -2.00 to -0.00, p=0.05). When acupuncture was compared with sham acupuncture, 10 points pain score was significantly lower in acupuncture group (MD=-0.39, 95% CI: -0.65 to -0.14, p=0.002, $I^2=0%$). Any serious adverse events were not reported. Conclusion: This review shows that acupuncture may be considered for postoperative pain in patients with solid tumor without serious adverse events. However, only a few studies were included in this study, further investigation is needed in this area.

  • Purpose : Lung cancer induces a decrease in physical activity and a deterioration of respiratory ability. Exercise is an effective treatment to reduce side effects of anti-cancer treatments, also influence the survival and successful rehabilitation in lung cancer patients. However, there is insufficient evidence to show which period is the most effective to apply exercise for lung cancer patients. Therefore, this study was conducted to evaluate the efficacy of exercise-based interventions before and after surgery. Methods : Clinical trials (CTs) and randomized controlled trials (RCTs) reported in PubMed database were investigated. The trials investigated in this study were published for 10 years before August 20, 2022. The risk of bias was judged according to the Cochrane guideline. The materials included in this meta-analysis were 6-minute walk test (6MWT), pulmonary function, and quality of life (QOL). Results : 1 CT and 9 RCTs were selected in current study. In the meta-analysis, exercise increased 6MWT in preoperation (mean difference [MD] 29.49; 95 % confidence interval [CI] .99 to 57.99; p=.04; I2=0 %), 3 months postoperation (MD 54.97; 95 % CI 31.85 to 78.09; p<.001; I2=45 %) and 6 months postoperation (MD 85.59; 95 % CI 45.06 to 126.12; p<.001; I2=47 %). Exercise, also enhanced the lung function such as FEV1/FVC (%) in postoperation (MD 7.64; 95 % CI 6.26 to 9.02; p<.001; I2=19 %). Additionally, exercise improved QOL, such as preoperative EORTC-QLQ-C30-LC13 in mental function (MD 3.21; 95 % CI .64 to 5.79; p=.01; I2=0 %) and postoperative SF-36 in mental component summary (MD 9.24; 95 % CI 4.94 to 13.54; p<.001; I2=0%). Conclusion : These results indicate that exercise-based intervention can elevate the ability to exercise and the mental componentof QOL within 3 months.

  • 본 연구는 무릎 골관절염 환자를 대상으로 수중운동과 지상운동의 효과를 비교하기 위해 수행된 체계적 문헌고찰 및 메타분석 연구이다. 문헌은 Ovid-Medline, Cochrane Library CENTRAL, CINAHL과 국내 DB인 RISS와 KISS를 통해 ((osteoarthriti* OR OA) AND (aqua* OR water OR hydrotherap*)), (골관절염 AND 수중운동) 등을 주요어로 조합하여 검색하였으며, 선택배제과정을 거쳐 최종 7편(n=449)의 문헌이 분석에 포함되었다. 문헌에 대한 질 평가는 SIGN의 무작위임상시험평가도구를 사용하였으며, 질 평가 결과는 6편에서 ++, 1편에서 +로 평가되어 전반적으로 비뚤림 위험은 없는 것으로 판단하였다. 메타분석결과 운동 중재 후 수중운동군과 지상운동군의 통증변화에 대한 차이는 Standardized mean difference (SMD) -0.26(95% CI -0.49, -0.03, p=0.03, $I^2=14%$)으로 수중운동군이 지상운동군에 비해 통증이 통계적으로 유의하게 감소하는 것으로 나타났으나, 그 외 두 군간 굴곡 관절가동범위, 신전 관절가동범위, 신체기능, 삶의 질의 SMD는 각각 -0.12(95% CI -0.51, 0.27, p=0.53, $I^2=0%$), -0.04(95% CI -0.55, 0.48, p=0.89, $I^2=43%$), -0.12(-0.44, 0.19, p=0.44, $I^2=0%$), -0.15(-0.54, 0.24, p=0.46, $I^2=0%$)로 두 군간 통계적으로 유의한 차이가 없는 것으로 나타났다. 현재 시점에서 무릎 골관절염환자를 대상으로 수중운동과 지상운동의 효과를 분석한 무작위 대조군 실험 연구 수가 비교적 적어 효과크기에 대한 확증적 결과를 얻는 데에는 다소 제한이 있었으므로 향후 이와 관련된 무작위 임상시험연구와 장기적인 효과검증에 대한 노력이 지속적으로 이루어져야 할 것으로 사료된다.
