Background
Central neck dissection and total thyroidectomy are standard treatments for patients with papillary thyroid carcinoma (PTC) with clinically involved central nodes. However, prophylactic ...central neck dissection (pCND) in patients with clinically uninvolved cN0 has been beneficial in some studies but ineffective in others. We conducted a meta-analysis to evaluate the efficacy and safety of pCND in patients with central neck lymph nodes cN0 PTC.
Methods
The PubMed, EMBASE, Cochrane Library, and Scopus databases and the ClinicalTrials.gov registry were electronically searched for studies published until September 2017. The meta-analysis was conducted to calculate the pooled effect size by using random-effects model. Treatment efficacies were measured by determining locoregional recurrence (LRR). Secondary outcomes included transient recurrent laryngeal nerve (RLN) injury, permanent RLN injury, transient hypocalcemia, and permanent hypocalcemia.
Results
Twenty-three retrospective and prospective cohort studies involving 18,376 patients were reviewed. Patients who underwent pCND had significantly lower LRR (odds ratio OR 0.65; 95% confidence interval CI 0.48–0.88) but significantly higher incidence rates of transient RLN injury (OR 2.03; 95% CI 1.32–3.13), transient hypocalcemia (OR 2.23; 95% CI 1.84–2.70), and permanent hypocalcemia (OR 2.22; 95% CI 1.58–3.13) than that of no pCND group.
Conclusion
Compared with no pCND, pCND significantly reduces LRR but is accompanied by numerous adverse effects. The clinical decision should be made after the shared decision-making process of clinicians and patients.
Background
Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Mindfulness and meditation therapies have been demonstrated as effective alternative treatments for ...patients with neurological disorders. However, the effects of mindfulness and meditation therapies on PD remain unclear. This meta‐analysis investigated the effects of mindfulness and meditation therapies in PD patients.
Methods
A literature search was conducted using PubMed, Embase, Cochrane Library, and ClinicalTrials.gov for randomized controlled trials comparing mindfulness and meditation therapies with control treatments in patients with PD.
Results
Nine articles involving eight trials were included, with a total of 337 patients. Our meta‐analysis revealed that mindfulness and meditation therapies significantly improved Unified Parkinson's Disease Rating Scale‐Part III score (mean difference MD = −6.31, 95% confidence interval 95% CI = −8.57 to −4.05) and cognitive function (standard mean difference SMD = 0.62, 95% CI = 0.23 to 1.02). However, no significant differences were discovered between mindfulness therapies and control in gait velocity (MD = 0.05, 95% CI = −0.23 to 0.34), Parkinson's Disease Questionnaire‐39 Summary Index (MD = 0.51, 95% CI = −1.12 to 2.14), activities of daily living (SMD = −1.65, 95% CI = −3.74 to 0.45), depression (SMD = −0.43, 95% CI = −0.97 to 0.11), anxiety (SMD = −0.80, 95% CI = −1.78 to 0.19), pain (SMD = 0.79, 95% CI = −1.06 to 2.63), or sleep disturbance (SMD = −0.67, 95% CI = −1.58 to 0.24).
Conclusion
Mindfulness and meditation therapies may serve as complementary and alternative treatments for PD patients.
Background
Hernia repair with mesh in patients with incarcerated or strangulated hernias is controversial. Moreover, the use of mesh for hernia repair with concomitant bowel resection poses a great ...dilemma. This study compared the outcomes of mesh and anatomic repairs in patients with acutely incarcerated or strangulated hernias.
Methods
PubMed, Embase, and Cochrane databases were searched for studies published before November 2019. Randomized controlled trials (RCTs) and prospective studies were included. We conducted meta-analyses using a random-effects model. The treatment outcome was measured by the incidence of surgical site infection (SSI), seroma formation, and hernia recurrence postoperatively.
Results
Two RCTs and six prospective studies with 978 patients were included. No significant difference in SSI incidence was observed between patients with incarcerated hernia from the mesh and anatomic repair groups. Recurrence was significantly lower in mesh repair group than in anatomic repair group (odds ratio, 0.08; 95% confidence interval, 0.01–0.45). Only two patients needed to have mesh explantation due to mesh infection. In the setting of hernia repair with concomitant bowel resection, the SSI rate with mesh repair was slightly higher, but most cases of infections were well controlled with conservative antibiotic therapy.
Conclusions
Mesh repair for incarcerated or strangulated hernias was feasible with a great benefit of lower recurrence rates. However, due to limited data, drawing conclusions regarding the use of mesh for hernia repair with concomitant bowel resection was difficult. Further studies with preset criteria for evaluating patients undergoing concomitant bowel resection may help elucidate this issue.
Background
After the publication of the Z0011 trial, the American Society of Clinical Oncology published an updated clinical practice guideline stating that clinicians should not recommend axillary ...lymph node dissection (ALND) for early-stage breast cancer patients with the involvement of one or two sentinel lymph nodes (SLNs). However, these recommendations have been challenged because they were mainly based on data from limited studies. The aim of the current study is to systematically compare the real-world outcomes of SLN biopsy (SLNB) alone and SLNB + ALND in patients with early-stage breast cancers and limited positive SLN metastasis in the post-Z0011 era
Patients and Methods
We searched articles in the PubMed, EMBASE, and Cochrane library databases. The primary endpoints were overall survival (OS) and disease-free survival (DFS). The secondary endpoints were recurrence rate and the incidence of lymphedema.
Results
One randomized controlled trial and six retrospective studies with 8864 patients were retrieved. For patients with early-stage breast cancer with one or two SLN metastases, receiving SLNB alone showed no significant difference in OS, DFS, and recurrence rate compared with receiving SLNB + ALND. The incidence of lymphedema in patients who received SLNB alone was significantly lower than those who received SLNB + ALND (odds ratio 1.95, 95% confidence interval 1.02–3.71).
Conclusions
Current real-world evidence proved that the Z0011 strategy is safe with respect to survival outcomes and effective in reducing the incidence of lymphedema. ALND should be avoided in patients with early-stage breast cancer with one or two SLN metastases in the post-Z0011 era.
Background Anticoagulation of the extracorporeal circuit is required in continuous renal replacement therapy (CRRT). Heparin is the classic choice for anticoagulation, although it may increase the ...risk of bleeding. Regional citrate anticoagulation reduces the risk of bleeding, but may cause hypocalcemia and metabolic disturbances. Study Design Systematic review and meta-analysis of randomized controlled trials (RCTs). Setting & Population Patients admitted to the intensive care unit with acute kidney injury that required CRRT. Selection Criteria for Studies RCTs regardless of publication status or language. Intervention Regional citrate versus heparin anticoagulation in CRRT. Outcomes The primary outcomes were circuit survival time, the occurrence of major bleeding defined as a site of gross bleeding with a decrease in blood pressure or requiring transfusion of 2 or more units of red blood cells, metabolic alkalosis, hypocalcemia, and thrombocytopenia. The secondary outcome was cost. Results 6 RCTs with 488 patients were identified. Citrate anticoagulation was associated with a significant decrease in bleeding (RR, 0.34; 95% CI, 0.17-0.65). Circuit survival time, the incidence of metabolic alkalosis, and thrombocytopenia showed no significant difference between groups. Hypocalcemia was more common in patients receiving citrate, although no clinical adverse event was reported in the included studies. Limitations Significant heterogeneity in the primary outcome. Conclusion The efficacy of citrate and heparin anticoagulation for CRRT was similar. However, citrate anticoagulation decreased the risk of bleeding with no significant increase in the incidence of metabolic alkalosis. We recommend citrate as an anticoagulation agent in patients who require CRRT but are at high risk of bleeding.

Purpose
Chemotherapy-induced nausea and vomiting (CINV) commonly occurs after chemotherapy, adversely affecting patients’ quality of life. Recently, studies have shown inconsistent antiemetic effects ...of two common 5-hydroxytryptamine 3 receptor antagonists, namely, palonosetron and granisetron. Therefore, we conducted a meta-analysis to evaluate the effectiveness of palonosetron versus granisetron in preventing CINV.
Methods
Relevant studies were obtained from PubMed, Embase, and Cochrane databases. The primary outcome was the complete response (CR) rate. Secondary outcomes were headache and constipation events.
Results
In total, 12 randomized controlled trials and five retrospective studies were reviewed. Palonosetron was consistently statistically superior to granisetron in all phases in terms of the CR rate (acute phases: odds ratio OR = 1.28, 95% confidence interval CI = 1.06–1.54; delayed phases: OR = 1.38, 95% CI = 1.13–1.69; and overall phases: OR = 1.37, 95% CI = 1.17–1.60). Moreover, a non-significant difference was found between the two groups in terms of the headache event, but the occurrence of the constipation event was lower in the granisetron group than in the palonosetron group.
Conclusion
Palonosetron showed a higher protective efficacy in all phases of CINV prevention, especially in delayed phases, and no relatively severe adverse effects were observed.
The c-Jun N-terminal kinases (JNKs) are a group of mitogen-activated protein kinases (MAPKs). JNK is mainly activated under stressful conditions or by inflammatory cytokines and has multiple ...downstream targets for mediating cell proliferation, differentiation, survival, apoptosis, and immune responses. JNK has been demonstrated to have both tumor promoting and tumor suppressing roles in different cancers depending on the focused pathway in each study. JNK also plays complex roles in the heterogeneous tumor microenvironment (TME). JNK is involved in different tumorigenesis pathways. TME closely relates with tumor development and consists of various stressful and chronic inflammatory conditions along with different cell populations, in which the JNK pathway may have various mediating roles. In this review, we aim to summarize the present knowledge of JNK-mediated processes in TME, including hypoxia, reactive oxygen species, inflammation, immune responses, angiogenesis, as well as the regulation of various cell populations within TME. This review also suggests future research directions for translating JNK modulation in pre-clinical findings to clinical benefits.
Whether a transumbilical or periumbilical incision is beneficial for the initial peritoneal access in laparoscopic abdominal surgery has been debated. Our aim is to determine whether a transumbilical ...or periumbilical incision is a better route for the initial umbilical trocar.
PubMed, Embase, and Cochrane Library databases were searched for articles published before March 2020. The meta-analysis calculated the pooled effect size by using a random effects model.
Five trials involving 783 patients were reviewed. The transumbilical group significantly reduced operation time (mean difference: −7.73; 95% confidence interval: −13.10 to −2.35) when compared to the periumbilical group. The length of hospital stay, mean pain scores on operation day and postoperation day 1 did not differ significantly between the two groups. Moreover, the incidence of surgical site infection, cosmetic satisfaction, and complication rate did not differ significantly between groups.
A transumbilical incision is better than a periumbilical incision for laparoscopic surgery as it saves operation time. Hence, we suggest transumbilical incisions for the initial peritoneal access in laparoscopic abdominal surgery.
•Transumbilical or periumbilical incisions are beneficial in laparoscopic surgery.•Compared with periumbilical group, transumbilical group significantly reduced operation time.•Incidence of surgical site infection, cosmetic satisfaction, and complication rate did not differ.•Transumbilical incision for initial access in laparoscopic surgery is suggested.
Background
Evidence on the accuracy of sentinel lymph node biopsy (SLNB) after neoadjuvant therapy (NAT) for patients with breast cancer is inconclusive. This study reviewed the real-world data to ...determine the acceptability of SLNB after NAT.
Methods
The study searched for articles in the PubMed, EMBASE, and Cochrane Library databases. The primary outcomes were the identification rate for sentinel lymph nodes (SLNs) and the false-negative rate (FNR) for SLNB. The study also evaluated the FNR in subgroups defined by tumor stage, nodal stage, hormone receptor status, human epidermal growth factor receptor-2 status, tumor response, mapping technique, and number of SLNs removed.
Results
The study retrieved 61 prospective and 18 retrospective studies with 10,680 initially cN± patients. The pooled estimate of the identification rate was 0.906 (95 % confidence interval CI, 0.891–0.922), and the pooled FNR was 0.118 (95 % CI, 0.103–0.133). In subgroup analysis, the FNR was significantly higher for the patients with estrogen receptor (ER)-negative status and fewer than three SLNs removed. The FNR did not differ significantly between the patients with and those without complete tumor response. Among the patients with initial clinical negative axillary lymph nodes, the incidence of node metastasis was 26.8 % (275/1041) after NAT.
Conclusion
Real-world evidence indicates that the FNR of SLNB after NAT in breast cancer is 11.8 %, exceeding only slightly the commonly adopted threshold of 10 %. The FNR is significantly higher for patients with ER-negative status and removal of fewer than three SLNs. Using a dual tracer and removing at least three SLNs may increase the accuracy of SLNB after NAT.
