Published: May 2021

Background:

Studies suggest that exposure to pesticides during pregnancy and early childhood is associated with adverse child neurodevelopment. Research to date has focused primarily on exposure to single pesticides or pesticide classes in isolation; there are little data on the effect of exposure to pesticide mixtures on child and adolescent neurodevelopment.

Methods:

Using California’s Pesticide Use Reporting database, we estimated agricultural pesticide use within 1 km of the home during the prenatal and postnatal (ages 0–5 years) periods among participants in the Center for the Health Assessment for Mothers and Children of Salinas (CHAMACOS) birth cohort. We implemented a Bayesian Hierarchical linear mixed-effects model to examine associations with maternal- and youth-reported behavioral and emotional problems from the Behavior Assessment System for Children, 2nd edition (BASC-2) at ages 16 and 18 years (n = 593).

Results:

We observed mostly null associations between pesticide applications and neurobehavioral outcomes. There were some trends of modestly increased internalizing behaviors and attention problems in association with organophosphate insecticide use near the home during the prenatal period. In the postnatal period, a two-fold increase in glyphosate applications was associated with more youth-reported depression (β = 1.2, 95% credible intervals [CrI] = 0.2, 2.2), maternal-reported internalizing behaviors (β = 1.23, 95% CrI = 0.2, 2.3), and anxiety (β = 1.2, 95% CrI = 0.2, 2.3). We observed some protective associations with imidacloprid during the prenatal period, particularly in sex-specific analyses.

Conclusions:

We found only some subtle associations between some pesticides and neurobehavioral outcomes. This study extends previous work by considering potential exposure to mixtures of pesticides.

Published: May 2021

Objectives:

To identify differences in risk of ill-health retirement (IHR) between groups with different levels of education and examine this difference with respect to working conditions and health-related factors.

Methods:

This study analysed the longitudinal data of 1691 paid workers aged 45 to 79 years from the Korean Longitudinal Study of Aging. Multivariate Cox regression analyses were conducted to identify the predictors and build a prediction model for IHR according to different final education levels.

Results:

Over the 10-year follow-up, 208 workers exited work because of poor health. Clear educational inequalities in reason of retirement and increased risk of IHR in low, intermediate, and high educational groups were observed.

Conclusions:

Our results suggest an educational gradient for IHR among Korean male workers and revealed gender differences in the risk of IHR.

Objective:

To analyze workplace outbreaks by industry sector in the first wave of the pandemic, and associated household cases.

Methods:

Number, size, and duration of outbreaks were described by sector, and outbreak cases were compared to sporadic cases in the same time frame. Address matching identified household cases with onset ≥2 days before, ≥2 days after, or within 1 day of the workplace outbreak case.

Results:

There were 199 outbreaks with 1245 cases, and 68% of outbreaks and 80% of cases belonged to (1) Manufacturing, (2) Agriculture, Forestry, Fishing, Hunting, (3) Transportation and Warehousing. There were 608 household cases associated with 339 (31%) outbreak cases, increasing the burden of illness by 56%.

Conclusions:

Workplace outbreaks primarily occurred in three sectors. Prevention measures should target industry sectors at risk to prevent spread in and out of the workplace.

Published: May 2021

Background:

Coronavirus disease 2019 (COVID-19) patients suffer from anxiety, depression, and sleep disorder due to isolation treatment and other reasons. Whether life interventions can be an alternative therapy for COVID-19 patients, accompanied with anxiety, depression, and sleep disorder, is controversial. Therefore, we conducted a meta-analysis and systematic review to evaluate the effects of life interventions on anxiety, depression, and sleep disorder in COVID-19 patients to provide some guidance for clinical application.

Methods:

The randomized controlled trials related to the life intervention and COVID-19 from inception to February 2021 will be searched. The following databases are our focused areas: the Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, EMBASE, Web of Science, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, and Wan Fang Database. Two investigators would independently screen the literature according to the inclusion and exclusion criteria, extract data, and evaluate the risk of bias in the included studies. Meta-analysis was performed with RevMan 5.3 software.

Results:

The results will provide a high-quality synthesis of current evidence for researchers in this subject area.

Conclusion:

The conclusion of our study will provide evidence for the judgment of whether life intervention is an effective intervention on COVID-19 patients.

Authors: Cui Chaohua , Hong Ye , Bao Jiajia , He Li
Published: May 2021

Leptomeningeal collateral flow (LMF) is associated with infarct area and clinical outcome for ischemic stroke patients. Although LMF can be detected by multiple imaging methods, but their diagnostic performance is uncertain.

The aim of this study was to evaluate the diagnostic validity or reliability of noninvasive image methods in assessing LMF.

Databases included PubMed, Web of Science, Embase, and Cochrane Library.

Original observational cohort studies.

Ischemic stroke patients.

Different noninvasive image methods to assess LMF.

Newcastle–Ottawa Scale to evaluate the quality of the studies; forest plot to show pooled results; I
2 and Egger test to evaluate the heterogeneity and publication bias.

Thirty of the 126 selected studies were eligible. For CT angiography, the interobserver agreement ranged from 0.494 to 0.93 and weighted kappa was 0.888; for patients receiving thrombolysis or endovascular treatment, 0.68 to 0.91; 0.494 to 0.89 for the 2-point system, 0.60 to 0.93 for the 3-point system, 0.68 to 0.87 for the system of >4 points; area under the curve (AUC) was 0.78. For perfusion computed tomography (CTP), the interobserver agreement ranged from 0.724 to 0.872; for patients receiving thrombolysis or endovascular treatment, 0.74 to 0.872; 0.724 for the 2-point system, 0.783 to 0.953 for the 3-point system; the intraobserver agreement was 0.884; AUC was 0.826. For MRI-fluid attenuated inversion recovery (FLAIR), the interobserver agreement ranged from 0.58 to 0.86; for patients receiving thrombolysis or endovascular treatment, 0.75 to 0.86; 0.86 for the two-point system, 0.77 to 0.87 for the system of more than 5 points; AUC was 0.82.

No pooled data of CTP and FLAIR. The difference cohort study had difference bias. The unpublished data were not included.

CT angiography is a good tool for assessing LMF. CTP shows a good validity and reliability, but its diagnostic value needs more evidence. FLAIR is a good modality to assess LMF. These image methods had better validity and reliability to evaluate LMF of patients receiving thrombolysis or endovascular treatment than all ischemic stroke patients.

Authors: Cao Shengqin , Wang Zhongfang , Li Chongyang , Wang Qiaoli
Published: May 2021

Background:

Osteoporosis (OP) is an age-related disease characterized by reduced bone mass and increased bone fragility. It is more common in older people and postmenopausal women. As a new type of exercise training for OP, whole-body vibration (WBV) exercise has been proved to have a good effect on postmenopausal women with OP. It can increase bone density and improve strength and balance in postmenopausal population, which has certain clinical value, but lacks evidence-based medicine evidence. This study aims to systematically study the effectiveness of WBV exercise on postmenopausal women with OP.

Methods:

The English databases (PubMed, Embase, Web of Science, The Cochrane Library) and Chinese databases (China National Knowledge Network, Wanfang, Weipu, China Biomedical Database) were searched by computer. From the establishment of the database to February 2021, the randomized controlled clinical studies on WBV exercise on postmenopausal women with OP were conducted. The quality of the included studies was independently extracted by 2 researchers and literature quality was evaluated. Meta-analysis of the included studies was performed using RevMan5.3 software.

Results:

In this study, the efficacy and safety of WBV exercise on postmenopausal women with OP were evaluated by lumbar spine bone density, femoral neck bone density, pain, incidence of falls, incidence of fractures, and quality of life scale score, etc.

Conclusion:

This study will provide reliable evidences for the clinical application of WBV exercise on postmenopausal women with OP.

Authors: Li Ying , Li Runmin , Li Xianhuang , Liu Liping , Zhu Jianting , Li Dongying
Published: May 2021

Background:

Type 2 diabetes is an emergent worldwide health crisis, and rates are growing globally. Aerobic exercise is an essential measure for patients with diabetes, which has the advantages of flexible time and low cost. Aerobic exercise is a popular method to reduce blood glucose. Due to the lack of randomized trials to compare the effects of various aerobic exercises, it is difficult to judge the relative efficacy. Therefore, we intend to conduct a network meta-analysis to evaluate these aerobic exercises.

Methods:

According to the retrieval strategies, randomized controlled trials on different aerobic exercise training will be obtained from China National Knowledge Infrastructure, WanFang, SinoMed, PubMed, Web of Science, EMBASE, and Cochrane Library, regardless of publication date or language. Studies were screened based on inclusion and exclusion criteria, and the Cochrane risk bias assessment tool will be used to evaluate the quality of the literature. The network meta-analysis will be performed in Markov Chain Monte Carlo method and carried out with Stata14 and OpenBUGS software. Ultimately, the evidentiary grade for the results will be evaluated.

Results:

Eighteen literatures with a total of 1134 patients were included for the meta-analysis. In glycemia assessment, Tennis (standard mean difference = 3.59, credible interval 1.52, 5.65), had significantly better effects than the named control group. Tennis (standard mean difference = 3.50, credible interval 1.05, 5.59), had significantly better effects than the named Taiji group.

Conclusion:

All together, these results suggest that tennis may be the best way to improve blood glucose in patients with type 2 diabetes. This study may provide an excellent resource for future control glycemia and may also serve as a springboard for creative undertakings as yet unknown.

Authors: Chai Yu-na , Luo Mi , Liang Wei-jie , Qiu Jian-li , Li Dangchi , Wang Li-chong , Tu Xing , Liu Cheng-ye , Qin Chong-Zhen , Li Duo-lu
Published: May 2021

Background:

Salvianolate, a common drug for stabilizing heart disease and Angina Pectoris, is considered to be off-label for preventing venous thromboembolism (VTE) or anticoagulation at present. However, many clinical studies have showed that salvianolate can effectively inhibit the deep-vein thrombosis (DVT) incidence, and prevent VTE of perioperative patients in the real world in China.

Objective:

This analysis aimed to evaluate the effectiveness and safety of salvianolate in preventing VTE in perioperative patients.

Methods:

Databases of PubMed, Cochrane Library, Embase, CNKI, Wanfang and VIP were searched until July 2019. Literature retrieval, data extraction and quality assessment were independently completed by two researchers and checked with each other. Review Manager 5.2 software was applied for meta-analysis.

Results:

A total of 429 studies were retrieved, including 11 randomized controlled trials (RCTs) with a total of 1149 subjects. Compared with low molecular weight heparin (LMWH) group alone, salvianolate combined LMWH group had lower DVT incidence in preventing perioperative thrombosis (2.75% and 14.23%, OR: 0.21, 95% CI:[0.08,0.53]; P = .0009). The incidence of adverse reactions of experimental group was similar to that of control group (1.79% and 2.31%, OR: 0.65, 95% CI:[0.18,2.35]. P = .51). Compared with the control group, D-dimer level (D-D), platelet count (PLT), fibrinogen (FIB), whole blood high shear viscosity (WBHSV), and whole blood low shear viscosity (WBLSV) were all significantly decreased (P < .01), and prothrombin time (PT) was significantly increased (P < .05).

Conclusion:

Salvianolate combined LMWH has better effectiveness and the same safety in preventing venous thromboembolism in perioperative patients. However, due to the small number of included literatures, large sample studies are still needed to further verify this conclusion.

Authors: Mun Seok Jun , Kim Si-Ho , Huh Kyungmin , Cho Sun Young , Kang Cheol-In , Chung Doo Ryeon , Peck Kyong Ran
Published: May 2021

Uncomplicated bacteremia and catheter-related bloodstream infection (CRBSI) are frequently suggested as factors associated with low risk of infective endocarditis in Staphylococcus aureus bacteremia (SAB). Nevertheless, guidelines recommend that echocardiography in all patients with SAB. We evaluated the effects of echocardiography on patient outcomes. Patients with uncomplicated S. aureus CRBSI were retrospectively identified between January 2013 and June 2018 at a 1950-bed, tertiary-care university hospital. Treatment failure was defined as any case of relapse or all-cause death within 90 days. Of 890 SAB patients, 95 with uncomplicated S. aureus CRBSI were included. Thirty-two patients underwent echocardiography within 30 days of their first positive blood culture. Two patients who underwent echocardiography revealed right-sided infective endocarditis. One patient who did not undergo echocardiography experienced recurrent SAB (peripheral CRBSI) 85 days after his first positive blood culture. There were no SAB-related deaths. The Kaplan–Meier curves of treatment failure showed no significant differences between patients who did and did not undergo echocardiography (P = .77). In multivariable analysis, risk factors for treatment failure were liver cirrhosis (hazard ratio: 9.60; 95% confidence interval: 2.13–43.33; P = .003) and other prostheses (hazard ratio: 63.79; 95% confidence interval: 5.05–805.40; P = .001). This study did not verify the putative association between treatment failure and implementation of echocardiography in patients with uncomplicated S. aureus CRBSI. Given the low observed rates of adverse outcomes, routine echocardiography might not be obligatory and could be performed on an individual basis.
Perioperative dexmedetomidine reduces emergence agitation without increasing the oculocardiac reflex in children
Authors: Song Jingyao , Liu Shuyan , Fan Bin , Li Guangyu , Sun Qianchuang
Published: May 2021

Background:

Intravenous dexmedetomidine (DEX) has been used to prevent emergence agitation (EA) in children. The aim of this meta-analysis was to evaluate whether DEX decreases EA incidence without augmenting oculocardiac reflex (OCR) in pediatric patients undergoing strabismus surgery.

Methods:

We searched PubMed, EMBASE, Chinese National Knowledge Infrastructure (CNKI), Wan Fang, and the Cochrane Library to collect the randomized controlled trials (RCTs) investigating the effects of intraoperative DEX in children undergoing strabismus surgery from inception to October 2019. Postoperative Pediatric Agitation and Emergence Delirium (PAED) score, postoperative EA, extubation or laryngeal mask airway (LMA) removal time, postanesthetic care unit (PACU) stay time, OCR, and postoperative vomiting (POV) were evaluated.

Results:

11 RCTs including 801 patients were included in this study. Compared with control group, intravenous DEX significantly reduced postoperative PAED score (WMD, 3.05; 95% CI: -3.82 to -2.27, P = .017) and incidences of postoperative EA 69% (RR, 0.31; 95% CI: 0.17 to 0.55, P < .00) and POV (RR, 0.28; 95% CI: 0.13 to 0.61, P = .001). Furthermore, the use of DEX significantly delayed extubation or LMA removal time (WMD, 2.11; 95% CI: 0.25 to 3.97, P < .001). No significant difference was found in the incidence of ORC and PACU stay time.

Conclusion:

Intravenous DEX reduced the incidences of EA without increasing OCR in pediatric patients undergoing strabismus surgery. Meanwhile, DEX infusion decreased the incidence of POV in children.

Authors: Sun Miaomiao , Wang Wanchao , Liu Xining , Wang Yiming , Cui Haozhe , Liu Siqing , Cao Liying
Published: May 2021

Previous studies have shown that serum total cholesterol (TC) and serum alanine aminotransferase (ALT) are associated with liver cancer risk. However, the common contribution of TC and normal-high ALT to primary liver cancer (PLC) has not been reported. We aim to assess the separate and joint effect of low TC level and normal-high ALT level on the risk of PLC, a large prospective cohort was conducted in our study.

The participants were divided into 4 groups via the cross-matching method according to TC [low level (−)/non-low level (+)] and ALT [normal level (−)/normal-high level(+)] status, and using the lower quartile value of TC and the upper quartile value of ALT as a threshold, respectively. Incident PLC was confirmed by review of medical records. Cox proportional hazards regression models and interactive additive models were used to evaluate whether the joint effect of low TC level and normal-high ALT level is associated with the risk of PLC.

During 1,248,895 person-years follow-up, 298 participants were diagnosed with PLC among 114,972 subjects. In male population, TC < 4.24 mmol/L was group “TC (−)”; TC ≥ 4.24 mmol/L was group “TC (+)”; ALT < 23 U/L was group “ALT (−)”: 33 U/L ≥ ALT ≥ 23 U/L was group “ALT (+)”. Compared with the group “TC (+)”, group “ALT (−)”, respectively, the adjusted hazard ratio (HR) and 95% confidence interval (95%CI) for PLC risk was 1.74 (1.36–2.25) in group “TC (−)” and 1.49 (1.15–1.94) in group “ALT (+)”. In combinatorial analysis, compared with group “TC (+) and ALT (−)”, the significant increased risk of PLC were observed in group “TC (+) and ALT (+)” (HR = 1.41; 95% confidence intervals [CI]: 1.02–1.95), group “TC (−) and ALT (−)” (HR = 1.67; 95%CI: 1.24–2.27) and group “TC (−) and ALT (+)” (HR = 2.72; 95%CI: 1.81–4.09), respectively. However, no statistical significance was found among female.

The separate and joint effect of low TC level and normal-high ALT level was observed for PLC risk in males. When combined, individuals with coexistence of low TC level and normal-high ALT level significantly increase the risk of PLC.

Published: May 2021

This study aimed to compare interphase fluorescence in situ hybridization (iFISH) and multiplex ligation dependent probe amplification (MLPA) for identifying genetic changes in myelodysplastic syndromes (MDS).

The frequencies of cytogenetic changes in MDS patients treated at the Institute of Hematology and Blood Disease Hospital (China) in 2009 to 2018 were assessed by iFISH based on bone marrow samples. Then, the effectiveness of MLPA in detecting these anomalies was evaluated.

Specimens from 287 MDS patients were assessed. A total of 36.9% (103/279) of MDS cases had chromosomal abnormalities detected by iFISH; meanwhile, 44.1% (123/279) harbored ≥1 copy-number variation (CNV) based on MLPA: +8 (n=46), −5 (n = 39), −7 (n = 27), del 20 (n = 32) and del 17 (n = 17). Overall, 0 to 4 aberrations/case were detected by MLPA, suggesting the heterogeneous and complex nature of MDS cytogenetics. There were 29 cases detected by MLPA, which were undetected by FISH or showed low signals. Sixteen of these cases had their risk classification changed due to MLPA detection, including 9 reassigned to the high-risk IPSS-R group. These findings demonstrated that MLPA is highly efficient in assessing cytogenetic anomalies, with data remarkably corroborating FISH findings (overall consistency of 97.1%). The sensitivities of MLPA in detecting +8, −5, −7, del 20 and del 17 were 92.3%, 97.1%, 100%, 100%, and 90%, respectively, with specificities of 95.8%, 97.6%, 97.7%, 97.6%, and 97%, respectively.

MLPA represents a reliable approach, with greater efficiency, accuracy, and speed than iFISH in identifying cytogenetic aberrations in MDS.
Comparison of efficacy and safety of complementary and alternative therapies for scapulohumeral periarthritis
Authors: Gao Meihan , Cong Haibo , Li Chuancheng , Qin Xiuyun , An Hongqiang , Jiang Zhenyuan
Published: May 2021

Background:

Scapulohumeral periarthritis is a disease with high incidence and great pain. The current western treatments with many side effects, poor efficacy cannot fundamentally solve the problem. Complementary and alternative therapies have played an excellent role in the treatment of scapulohumeral periarthritis. However, it is not clear which complementary and alternative therapy is more effective. Therefore, we propose a protocol to compare the efficacy and safety of various complementary and alternative therapies through network meta-analysis (NMA) to provide choice guidance for the therapy.

Methods:

A comprehensive search will be conducted for randomized controlled trials of complementary and alternative therapy for scapulohumeral periarthritis as well as ongoing trials. The time limit is from the establishment of the database until January 2021. Literature and data extraction were completed independently by two researchers. Through pairwise comparison and meta-analysis of Bayesian NMA, all the evidences are evaluated comprehensively. STATA16.0 and WinBUGS1.4.3 software will be used for data processing and analysis, and recommendation evaluation will be used to develop and assess grades to classify the quality of NMA evidence.

Results:

Through the analysis, we will obtain the ranking of the efficacy and safety of different complementary and alternative therapies in the treatment of scapulohumeral periarthritis, in order to provide reference for clinical selection of treatment methods.

Conclusion:

Complementary and alternative therapies of scapulohumeral periarthritis plays a positive role in improving the symptoms of scapulohumeral periarthritis. This study can provide evidence support for clinicians and patients.

Communicating multiple tubular enteric duplication with toxic megacolon in an infant
Authors: Jang Eunju , Chung Jae Hee
Published: May 2021

Rationale:

Gastrointestinal tract duplication is a rare congenial anomaly which can be found anywhere along the gastrointestinal tract. While many patients are incidentally diagnosed during operation, in some cases it can present with severe gastrointestinal symptoms. In this case report, the patient presented with signs of toxic megacolon leading to rapid aggravation of inflammatory shock.

Patient concerns:

A 49-day old male infant presented with fever, poor feeding, and severe abdominal distension.

Diagnosis:

Abdominal ultrasonography was done. During the examination, a foley catheter was inserted through the anus to evaluate bowel patency and enable rectal decompression. The tip of the foley catheter was located in a separate narrower tubular lumen adjacent to the distended rectum. These findings suggested possibility of a tubular duplication cyst of the rectum as the culprit for the bowel obstruction.

Interventions:

The patient underwent emergency laparotomy. Findings showed multiple tubular intestinal duplications involving the ileum, appendix, cecum, descending colon, sigmoid colon and rectum. The true lumen of the rectosigmoid colon was completely collapsed while the adjacent tubular cyst remained severely distended and stool passage was not possible. Decompression of the sigmoid colon was done with loop colostomy with both the wall of the true bowel and enteric cyst forming the colostomy orifice.

Outcomes:

After 40 days of postoperative care, the patient was discharged with no immediate complications. Four months after the initial operation, colostomy take-down and transanal rectal common wall division was done. No complications were observed.

Lessons:

To our knowledge, this is the first case to be reported where a rare presentation of intestinal duplication resulted in an acute presentation toxic megacolon. Such emergency cases can be effectively treated with emergency surgical bowel decompression and elective common wall division.
Azathioprine-induced toxoplasma gondii infection in a patient with Crohn's disease with NUDT15 variation
Authors: Wu Yanan , Tan Yuyong , Ou Dalian , Wang Xuehong , Wang Yongjun
Published: May 2021

Introduction:

Azathioprine (AZA) has been widely used for the treatment of various immune-related diseases and has become a mainstay in the treatment of inflammatory bowel disease. However, patients with genetic mutations may experience severe adverse events when treated with azathioprine. Most of the previous literature focused on the TPMP gene-related adverse reactions, herein, we report a case of Crohn's disease patient with nucleoside diphosphate-linked moiety X motif 15 gene (NUDT15) variation and wild-type TPMP gene who developed toxoplasma gondii infection after azathioprine treatment.

Patient concerns:

A 56-year-old Crohn's disease patient developed toxoplasma gondii infection within 2 months after the administration of azathioprine; however, he had no relevant high-risk factors.

Diagnosis:

Subsequent genetic testing revealed that the patient was heterozygous for NUDT15. Therefore, it was reasonable to consider that the patient's genetic mutation resulted in reduced tolerance to azathioprine, leading to low immunity and eventually toxoplasma infection.

Interventions:

AZA was then discontinued; after anti-infection, antipyretic and other supportive treatments were administered, the patient's condition gradually improved.

Outcomes:

The patient was followed up at 1, 3, and 6 months after discharge; fortunately, he was in good health.

Conclusion:

We report a case of Crohn's disease in a patient who developed severe pneumonia caused by toxoplasma gondii infection due to the administration of AZA, with normal TPMP gene but NUDT15 gene mutation. This indicates that NUDT15 variation may contribute to severe adverse events in patients treated with azathioprine, and we suggest that NUDT15 genotype be detected before the use of azathioprine in order to provide personalized therapy and reduce side effects.
Long event-free survival after anti-BCMA CAR-T cell treatment for relapsed and refractory multiple myeloma patients
Authors: Xu Jinhuan , Ming Xi , Wang Chunyan , Xu Bi , Xiao Yi
Published: May 2021

Introduction:

Chimeric antigen receptor T (CAR-T) cells targeting B-cell maturation antigen (BCMA) have been used in the treatment of relapsed and refractory multiple myeloma (RRMM). The response rate and the depth of responses induced by anti-BCMA CAR-T cells are impressive. However, despite this, remissions are not sustained, and the majority of patients eventually relapse.

Patient concerns:

Two patients with multiple myeloma (MM) were selected to enroll in a phase I study involving anti-BCMA CAR-T cells (ChiCTR-OPC-16009113) because they did not have the good effect after traditional treatment. One is a 48-year-old male patient who received a diagnosis of IgG lambda MM in June 2015, he has received 4 cycles of cyclophosphamide, bortezomib, and dexamethasone (CyBorD) and obtained a complete response (CR). Approximately 11 months later, the disease progressed. Subsequent treatment included regimens incorporating liposomal doxorubicin, bortezomib, and dexamethasone (3 cycles); the response was poor, and the disease kept progressing. Another 65-year-old female patient received a diagnosis of IgG lambda MM in September 2016, she has received induction therapy with 1 cycle of bortezomib and dexamethasone (VD) and 4 cycles of lenalidomide and dexamethasone, the response was poor.

Diagnosis:

Both patients were diagnosed with RRMM according to the International Myeloma Working Group criteria.

Interventions:

Both patients received infusions of anti-BCMA CAR-T cells following an induction chemotherapy regimen of cyclophosphamide and fludarabine.

Outcomes:

Both of them achieved a stringent CR at the 30th day with minimal residual disease-negative bone marrow by flow cytometry and serum monoclonal protein was undetectable at 4 and 10 months after cell transfusion. The CR has persisted in the 2 patients for >36 months.

Conclusions:

Our findings demonstrate the anti-BCMA CAR-T cell treatment is a feasible therapeutic option for patients with RRMM. Fewer early lines of treatment may be beneficial to maintain the efficacy of CAR-T cells.

Authors: Hu Guanyu , Zhang Hongshi , Wang Yufeng , Cong Deyu
Published: May 2021

Background:

Post-stroke spasticity (PSS) is a major worldwide health problem, and timely and effective rehabilitation is associated with the risk of diabetes development; there are a variety of non-pharmacological interventions applied to the rehabilitation of PSS in these treatments; however, the relative efficacy and safety of different therapies remain uncertain, and we will conduct a systematic review and network meta-analysis to evaluate different non-pharmacological interventions. The relative efficacy and safety of intervention in PSS rehabilitation, thus providing evidence to support the optimization of the PSS rehabilitation program.

Methods:

We searched the following databases electronically, including four English literature databases (i.e., PubMed, Medline, Embase, and Cochrane Library) and two Chinese literature databases (i.e., China National Knowledge Infrastructure and VIP). We will also search for randomized controlled trials on non-pharmacological interventions for post-stroke spasticity, and the search time limit is from its establishment to May 2020. Two reviewers working independently will screen the titles, abstracts, and full papers. Data extraction will be completed by two independent authors. The primary outcome was the motor function. The secondary outcome was the assessment of daily living ability. We will use RevMan V.5.3 software to compute the data synthesis carefully when a meta-analysis is allowed. We will conduct Bayesian network meta-analysis using the Markov Chain Monte Carlo random effects model in Aggregate Data Drug Information System version 1.16.8 (Drugis, Groningen, NL).

Results:

This study provides a high-quality synthesis to assess the effectiveness and safety of non-pharmacological interventions for patients with PSS.

Conclusion:

The results of this study will provide evidence to judge whether non-pharmacological interventions are effective interventions for patients with post-stroke spasticity.

Ethics and dissemination:

The results of this meta-analysis and meta-regression will be disseminated through publication in a peer-reviewed journal and presented at a relevant conference. The data used in the network meta-analysis did not contain individual patient data. Therefore, ethical approval was not required.

Epidemiology and factors associated with the severity of viral acute lower respiratory infection in children hospitalized in Manaus, Amazonas, in 2017–2018
Authors: Sobrinho Fabrícia L.D.V. , Aragon Davi C. , Carlotti Ana P.C.P.
Published: May 2021

To investigate the epidemiology and factors associated with the severity of viral acute lower respiratory infection (ALRI) in children hospitalized in Manaus, Amazonas, in 2017 to 2018.

Retrospective cohort study of children hospitalized at the Hospital and Emergency Room Delphina Rinaldi Abdel Aziz, in Manaus, from April 01, 2017 to August 31, 2018, with a clinical diagnosis of ALRI and nasopharyngeal aspirates positive for at least 1 respiratory virus.

One hundred forty-six children aged 0.2 to 66 months (median 7 months) were included. Patients were divided into 2 groups according to the disease severity classified by an adapted Walsh et al score: moderate disease, score 0–4, n = 66 (45.2%) and severe disease, score 5–7, n = 80 (54.8%). A greater number of viral ALRI cases were observed in the rainiest months. Respiratory syncytial virus was the most prevalent (n = 103, 70.3%), followed by metapneumovirus (n = 24, 16.4%), influenza virus (n = 17, 11.6%), parainfluenza virus (n = 11, 7.5%), and adenovirus (n = 4, 2.7%). Co-detections of 2 to 3 viruses were found in 12 (8.2%) patients. The presence of viral coinfection was an independent risk factor for disease severity (adjusted relative risk [RR] 1.53; 95% CI 1.10–2.14). Twelve patients (8.2%) died, all with severe disease. Risk factors for death were shock (adjusted RR 10.09; 95% CI 2.31–43.90) and need for vasoactive drugs (adjusted RR 10.63; 95% CI 2.44–46.31).

There was a higher incidence of viral ALRI in Manaus in the rainy season. Respiratory syncytial virus was the most prevalent virus. The presence of viral coinfection was an independent risk factor for disease severity.

Authors: Zhang Hao-Yang , Huang Han , Pang Li-Jian , Lv Xiao-Dong , Zheng Wei-Dong
Published: May 2021

Background:

Acute exacerbation is a primary cause of repeated hospitalization and death in chronic obstructive pulmonary disease (COPD) patients. Therefore, how to control the symptoms of COPD at stable stage and reduce the number of acute exacerbation is a hot spot of medical research. Acupoint application (AA) is a significant part of external treatment of traditional Chinese medicine (TCM), Previous researches have reported that AA can be applied to the treatment of COPD. Nevertheless, its effectiveness is still inconclusive. This systematic review (SR) and meta-analysis is designed to appraise its effectiveness and safety for the treatment of patients with COPD.

Methods:

Eight databases will be systematically retrieved from their inceptions to February 2021. Inclusion criteria are randomized control trials of AA combined with routine western medicine interventions in the treatment of COPD at stable stage. The primary outcomes we focus on comprise clinical effective rate, TCM symptom score, quality of life, dyspnea, exercise capacity, lung function, frequency of acute exacerbation, adverse events. The research screening, data extraction, and risk of bias assessment will be conducted by 2 individuals independently, and divergence will be adjudicated by a third senior investigator. The Stata 13.1 software will be used for meta-analysis. The confidence of evidence will be classified adopting grading of recommendations assessment, development and evaluation (GRADE) algorithm and methodological quality of this SR will be assessed using assessment of multiple systematic reviews-2 (AMSTAR-2) tool.

Results:

This SR will provide evidence-based medical proof for the treatment of COPD at stable stage by AA combined with conventional western medicine interventions. The findings of this SR will be presented at relevant conferences and submitted for peer-review publication.

Conclusions:

The findings of this SR will provide up-todated summary proof for evaluating the effectiveness and safety of AA for COPD.

MicroRNA-363-3p promote the development of acute myeloid leukemia with RUNX1 mutation by targeting SPRYD4 and FNDC3B
Authors: Chen Yimin , Chen Shuyi , Lu Jielun , Yuan Danyun , He Lang , Qin Pengfei , Tan Huo , Xu Lihua
Published: May 2021

Background:

Runt-related transcription factor 1 (RUNX1) is one of the most frequently mutated genes in most of hematological malignancies, especially in acute myeloid leukemia. In the present study, we aimed to identify the key genes and microRNAs based on acute myeloid leukemia with RUNX1 mutation. The newly finding targeted genes and microRNA associated with RUNX1 may benefit to the clinical treatment in acute myeloid leukemia.

Material/Methods:

The gene and miRNA expression data sets relating to RUNX1 mutation and wild-type adult acute myeloid leukemia (AML) patients were downloaded from The Cancer Genome Atlas database. Differentially expressed miRNAs and differentially expressed genes (DEGs) were identified by edgeR of R platform. Gene ontology and the Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed by Metascape and Gene set enrichment analysis. The protein–protein interaction network and miRNA-mRNA regulatory network were performed by Search Tool for the Retrieval of Interacting Genes database and Cytoscape software.

Results:

A total of 27 differentially expressed miRNAs (25 upregulated and 2 downregulated) and 561 DEGs (429 upregulated and 132 downregulated) were identified. Five miRNAs (miR-151b, miR-151a-5p, let-7a-2-3p, miR-363-3p, miR-20b-5p) had prognostic significance in AML. The gene ontology analysis showed that upregulated DEGs suggested significant enrichment in MHC class II protein complex, extracellular structure organization, blood vessel development, cell morphogenesis involved in differentiation, embryonic morphogenesis, regulation of cell adhesion, and so on. Similarly, the downregulated DEGs were mainly enriched in secretory granule lumen, extracellular structure organization. In the gene set enrichment analysis of Kyoto Encyclopedia of Genes and Genomes pathways, the RUNX1 mutation was associated with adherent junction, WNT signaling pathway, JAK-STAT signaling pathway, pathways in cancer, cell adhesion molecules CAMs, MAPK signaling pathway. Eleven genes (PPBP, APP, CCR5, HLA-DRB1, GNAI1, APLNR, P2RY14, C3AR1, HTR1F, CXCL12, GNG11) were simultaneously identified by hub gene analysis and module analysis. MicroRNA-363-3p may promote the development of RUNX1 mutation AML, targeting SPRYD4 and FNDC3B. In addition, the RUNX1 mutation rates in patient were obviously correlated with age, white blood cell, FAB type, risk(cyto), and risk(molecular) (P < .05).

Conclusion:

Our findings have indicated that multiple genes and microRNAs may play a crucial role in RUNX1 mutation AML. MicroRNA-363-3p may promote the development of RUNX1 mutation AML by targeting SPRYD4 and FNDC3B.
Bortezomib-based regimens improve the prognosis of newly diagnosed MM patients with chromosomal aberrations except for del(17q13)
Authors: Liu Zhigang , Zeng Qiang , Xiang Bing
Published: May 2021

Chromosomal aberrations are generally considered to have a remarkable impact on the outcome of multiple myeloma. Bortezomib helps to achieve complete responses and leads to longer life expectancy in many multiple myeloma patients. This study was designed to clarify whether bortezomib can improve the poor prognosis resulting from del(17q13), del(13q14), amp(1q21), t(4,14), t(14,16) in patients with multiple myeloma. A total of 255 MM patients treated with bortezomib-based regimens were included in this study. All chromosomal aberrations were detected by interphase fluorescence in situ hybridization. Kaplan–Meier survival and Multivariable Cox regression analysis were employed to assess the prognostic situation in progression-free survival and overall survival. The result showed that the progression-free survival and overall survival of patients with del(17q13) were shorter than those without del(17q13) in multivariate analysis and patients with del(13q14), amp(1q21), t(4,14), t(14,16) were similar to patients without these chromosomal aberrations in progression-free survival and overall survival after receiving bortezomib-based regimens.

In conclusion Bortezomib-based regimens can overcome the poor prognosis derived from del(13q14), amp(1q21), t(4,14), t(14,16) but not del(17q13).
Quality of end-of-life care of home-based care with or without palliative services for patients with advanced illnesses
Authors: Chiang Jui-Kun , Kao Yee-Hsin
Published: May 2021

Palliative care has improved quality of end-of-life (EOL) care for patients with cancer, and these benefits may be extended to patients with other serious illnesses. EOL care quality for patients with home-based care is a critical problem for health care providers. We compare EOL quality care between patients with advanced illnesses receiving home-based care with and without palliative services.

The medical records of deceased patients who received home-based care at a community teaching hospital in south Taiwan from January to December 2019 were collected retrospectively. We analyzed EOL care quality indicators during the last month of life.

A total of 164 patients were included for analysis. Fifty-two (31.7%) received palliative services (HP group), and 112 (68.3%) did not receive palliative services (non-HP group). Regarding the quality indicators of EOL care, we discovered that a lower percentage of the HP group died in a hospital than did that of the non-HP group (34.6% vs 62.5%, P = .001) through univariate analysis. We found that the HP group had lower scores on the aggressiveness of EOL care than did the non-HP group (0.5 ± 0.9 vs 1.0 ± 1.0, P<.001). Furthermore, palliative services were a significant and negative factor of dying in a hospital after adjustment (OR = 0.13, 95%CI = 0.05–0.36, P < .001).

For patients with advanced illnesses receiving home-based care, palliative services are associated with lower scores on the aggressiveness of EOL care and a reduced probability of dying in a hospital.
