Objective: To gather current evidence on the impact of antipsychotics on long-term mortality in patients with schizophrenia. Methods: We systematically searched for articles in Embase, PubMed, and PsycINFO reporting the long-term mortality (follow-up > 1 year) of patients with schizophrenia who were using any antipsychotics. We then conducted multiple meta-analyses to determine differences in long-term mortality between different types of antipsychotics. Results: We identified 45 articles that provided unadjusted long-term mortality rates, including 46,171 deaths during 2,394,911 person-years. The pooled mortality rate was 9.9 (95%CI = 7.4-12.7) per 1,000 person-years. The unadjusted crude mortality rate of antipsychotic drug users was lower than that of non-users (risk ratio [RR] = 0.546, 95%CI = 0.480-0.621), first-generation antipsychotics caused higher all-cause mortality than second-generation antipsychotics (RR = 1.485, 95%CI = 1.361-1.620), and polypharmacy had better effects than monotherapy on long-term mortality (RR = 0.796, 95%CI = 0.689-0.921). As for the causes of death, heart disease and cardiovascular disease ranked highest among cause-specific mortality (5.6 per 1,000 person-years). Conclusion: Since antipsychotics had a beneficial effect on long-term mortality in schizophrenia, greater precaution should be taken with patients who do not take them. However, since disease severity, comorbidities, and other confounding factors cannot be fully controlled, further research and verification are needed.

Resumo Fundamento A dupla antiagregação plaquetária (DAP) é o tratamento fundamental do infarto agudo do miocárdio (IAM). Objetivo O presente estudo visou investigar a eficácia e a segurança da tripla antiagregação plaquetária (TAP) em pacientes femininas idosas com diabetes e infarto agudo do miocárdio com supradesnível do segmento ST (IAMCSST), que foram submetidas à intervenção coronária percutânea ICP. Métodos Trata-se se de um estudo randomizado e mono-cego. O grupo controle A (97 pacientes idosos do sexo masculino com diabetes e STEMI, cujos escores CRUSADE foram < 30) recebeu aspirina, ticagrelor e tirofibana. Um total de 162 pacientes femininas idosas com diabetes e IAMCSST foram divididas aleatoriamente em dois grupos de acordo com o escore CRUSADE. O grupo B (69 pacientes com escore CRUSADE > 31) recebeu aspirina e ticagrelor. O grupo C (93 pacientes com escore CRUSADE < 30) recebeu aspirina, ticagrelor e tirofibana. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados Após a PCI, o fluxo sanguíneo grau 3 Thrombolysis in Myocardial Infarction (TIMI) e a perfusão miocárdica TIMI grau 3 foram significativamente menos prevalentes no grupo B, em comparação com o grupo A (p < 0,05). Quando comparada aos grupos A e C, a incidência de complicações adversas maiores foi significativamente maior no grupo B (p < 0,05). Conclusão A TAP pode efetivamente reduzir a incidência de complicações maiores em pacientes idosas com diabetes e IAMCSST. No entanto, atenção cuidadosa deve ser dada à hemorragia em pacientes que recebem TAP. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

Abstract Background Dual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI). Objective The present study aimed to investigate the efficacy and safety of triple antiplatelet therapy (TAPT) in elderly female patients with diabetes and ST segment elevation myocardial infarction (STEMI), who had undergone percutaneous coronary intervention (PCI). Methods We designed a randomized, single-blind study. Control group A (97 elderly male patients with diabetes and STEMI, whose CRUSADE scores were < 30) received aspirin, ticagrelor, and tirofiban. A total of 162 elderly female patients with diabetes and STEMI were randomly divided into two groups according to CRUSADE score. Group B (69 patients with CRUSADE score > 31) received aspirin and ticagrelor. Group C (93 patients with CRUSADE score < 30) received aspirin, ticagrelor and tirofiban. P values < 0.05 were considered statistically significant. Results Compared to the findings in group A, post-PCI Thrombolysis in Myocardial Infarction (TIMI) grade 3 blood flow and TIMI myocardial perfusion grade 3 were significantly less prevalent in group B (p < 0.05). When compared to groups A and C, the incidence of major adverse complications was significantly higher in group B (p < 0.05). Conclusion TAPT could effectively reduce the incidence of major complications in elderly female patients with diabetes and STEMI. However, close attention should be paid to hemorrhage in patients receiving TAPT. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)

RESUMO Introdução: A acupuntura tem sido amplamente utilizada para alívio de dor. No entanto, seus mecanismos são muito pouco conhecidos. Objetivo: Investigar a relação entre o efeito analgésico da eletroacupuntura e a regulação da expressão de adenosina e de substância P. Métodos: Utilizou-se um modelo de dor inflamatória crônica em ratos por injeção única do Adjuvante Completo de Freund e, em seguida, os animais foram tratados com eletroacupuntura diariamente. Foram aplicadas sete sessões bilaterais de eletroacupuntura (ST36 e BL60, 0,5 a 1,5 mA, força inicial de 0,5 mA, aumentada em 0,5 mA a cada 10 minutos, 30 minutos por sessão, uma sessão por dia) em ratos com Adjuvante Completo de Freund, por sete dias. O efeito analgésico da eletroacupuntura foi avaliado pela medida do limiar de retirada da pata em ratos que receberam estimulações mecânica e térmica. Resultados: A estimulação diária com eletroacupuntura aumentou efetivamente o limiar de retirada da pata em ratos com Adjuvante Completo de Freund. A eletroacupuntura aumentou o nível de adenosina na região zusanli. Estudos posteriores mostraram que a eletroacupuntura poderia diminuir os níveis de substância P, receptor de neurocinina-1, fator de necrose tumoral-alpha, interleucina-1β, interleucina-6 e CD68 nos gânglios da raiz dorsal. Curiosamente, a injeção direta de antagonistas do receptor de adenosina A1 ou de substância P, ou a transecção da raiz do nervo dorsal, podem prejudicar significativamente as ações analgésicas induzidas pela eletroacupuntura em ratos com Adjuvante Completo de Freund e reduzir os níveis de substância P, receptor de neurocinina-1, fator de necrose tumoral-alfa, interleucina-1β, interleucina-6 e CD68. Por fim, confirmamos que a injeção direta de um agonista do receptor da adenosina A1 reproduziu os efeitos analgésicos da eletroacupuntura. Conclusão: Nossos resultados indicam a regulação da secreção da substância P mediada pela adenosina. A via mediada pela substância P pode estar envolvida no processo de analgesia por eletroacupuntura em ratos.

ABSTRACT Background: Acupuncture has been widely used for alleviating pain. However, its mechanisms remain largely enigmatic. Objective: In the present study, we focused on whether the analgesic effect of electroacupuncture is related to its regulation on adenosine and substance P expression. Methods: We established chronic inflammatory pain model in rats through a single injection of Complete Freund’s Adjuvant, and then we treated animals using daily electroacupuncture. We applied seven bilateral sessions of electroacupuncture (ST36 and BL60, 0.5 to 1.5 mA, initial strength of 0.5 mA, increased by 0.5 mA every 10 minutes, for 30 minutes per session, one section per day) to Complete Freund’s Adjuvant rats for seven days. The analgesic effect of electroacupuncture was evaluated by measuring paw withdrawal threshold in rats that received mechanical and thermal stimulation. Results: Daily electroacupuncture stimulation effectively increased paw withdrawal threshold in Complete Freund’s Adjuvant rats. Electroacupuncture increased the adenosine level in zusanli. A further study showed that electroacupuncture could decrease substance P, neurokinin-1 receptor, tumor necrosis factor-alpha, interleukin-1β, interleukin-6 and CD68 levels in dorsal root ganglion. Interestingly, direct injection of adenosine A1 or substance P receptor antagonists, or dorsal nerve root transection could significantly impair electroacupuncture induced analgesic actions in Complete Freund’s Adjuvant rats could and reduce the levels of substance P, neurokinin-1 receptor, tumor necrosis factor-alpha, interleukin-1β, interleukin-6 and CD68. Finally, we confirmed that direct injection of adenosine A1 receptor agonist replicated the analgesic effect of electroacupuncture. Conclusion: Our results indicate regulation of adenosine-mediated substance P secretion. Substance P-mediated pathway may be involved in the analgesia process by electroacupuncture in rats.

ABSTRACT Purpose: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. Materials and Methods: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. Results: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. Conclusions: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

This is a retrospective, single-center observational study to explore the predictors of chest drainage for neonatal pneumothorax. A total of 183 neonates (age ≤28 days) who presented to the Children's Hospital of Soochow University between January 1, 2015 and December 31, 2018 for pneumothorax or developed pneumothorax during a hospital stay were included. Demographic data, clinical presentation, and imaging characteristics of neonatal pneumothorax were collected and analyzed. We used univariate and multivariate logistic regression analyses to determine significant predictors of chest drainage of pneumothorax in neonates. Pneumothorax occurred within 24 h after birth in 131 (71.6%) cases, between 24 and 48 h after birth in 41 (22.4%) cases, and 48 h after birth in 11 (6.0%) cases. Univariate and multivariate logistic regression analyses revealed that lung collapse ≥1/3 on initial chest X-ray (OR 4.99, 95%CI 2.25-11.07), chest retractions (OR 8.12, 95%CI 2.88-22.89), cyanosis (OR 2.25, 95%CI 1.08-4.66), and frothing from mouth (OR 2.49, 95%CI 1.12-5.49) (P<0.05 for all) were significant predictors of the need for chest drainage due to pneumothorax. In conclusion, the thorough evaluation of the above predictive factors can guide treatment and improve patient outcome.

ABSTRACT: Soil microorganisms are influenced by climate change. However, the effect of climate change on soil cultivable bacteria are unclear. In this study, the composition and diversity of the soil cultivable bacterial community were explored by a dilution–plate method, PCR, and 16S rRNA sequencing in a desert steppe of northern China after repeated NH4NO3 amendments and precipitation manipulation for seven years. The experimental treatments were as follows: control (CK), N addition (+N), N addition plus water addition (+N+W), and N addition plus water reduction (+N-W). Among the treatment groups, 11 genera and 17 bacterial species were isolated. Nitrogen addition and precipitation manipulation significantly increased the number of cultivable bacteria in the 0.00-0.30 m layer compared to CK. Compared to +N treatment, the +N+W and +N–W treatments had no significant impact on the number of cultivable bacteria. Compared to the CK community, bacterial communities exposed to the other three treatments did not show shifts in the relative abundance of dominant genera and other cultivable bacteria, except for Pontibacter and Staphylococcus. The treatments +N+W and +N-W significantly modified the relative abundance of Pontibacter and Staphylococcus compared to the +N treatment. Available potassium and phosphorus, and moisture content contributed to the change in the composition of the cultivable bacterial community (p>0.05). Nitrogen addition and precipitation manipulation significantly decreased species richness in the 0.00-0.02 m layer, but they did not affect evenness and the Shannon-Wiener Index in the 0.00-0.30 m layer. This study provides insights into how the composition and diversity of the bacterial community is affected by climate change scenarios.

ABSTRACT Mycobacterium sp. YC-RL4 is capable of utilizing a broad range of phthalic acid esters (PAEs) as sole source of carbon and energy for growth. The preliminary studies demonstrated its high degrading efficiency and good performance during the bioprocess with environmental samples. Here, we present the complete genome of Mycobacterium sp. YC-RL4, which consists of one circular chromosome (5,801,417 bp) and one plasmid (252,568 bp). The genomic analysis and gene annotation were performed and many potential genes responsible for the biodegradation of PAEs were identified from the genome. These results may advance the investigation of bioremediation of PAEs-contaminated environments by strain YC-RL4.

ResumoIntrodução:O stent coronário intravascular tem sido utilizado no tratamento de doença arterial coronária, com uma maior limitação de restenose intra-stent (RIS). O aço inoxidável 316 tem sido amplamente utilizado para stents. Neste estudo, foi desenvolvido um novo método de revestimento para reduzir a RIS para revestir simultaneamente o fator de crescimento endotelial vascular (VEGF) e anti-CD34 em aço inoxidável 316L.Métodos:Placas de aço inoxidável 316L redondas no grupo DH foram polimerizadas com compostos gerados a partir da reacção de condensação de dopamina e heparina utilizando N- (3-dimetilaminopropil) -N'-etilcarbodiimida (EDC) e N-hidroxissuccinimida (NHS). Dezesseis folhas a partir do grupo DH foram ainda imersas em 1 ug/ml de VEGF 165 e 3 mg/ml de heparina sódica, um após outro por 10 vezes, sendo denominado como o grupo D-(HV)10. Oito folhas de D-(HV)10 foram revestidas com anticorpo anti-CD34 e denominado como grupo D-(HV)10-A. Testes de imunofluorescência e ELISA foram usados para avaliar se os discos de aço inoxidável 316L foram revestidos com sucesso com VEGF e anticorpo anti-CD34.Resultados:Os resultados dos testes de imunofluorescência e ELISA mostraram que o VEGF pôde ser detectado nos grupos D-(HV)10 e D-(HV)10-A, evidenciando que as chapas de aço foram cobertas com VEGF com sucesso. O anticorpo anti-CD34 podia apenas ser observado no grupo D-(HV)10-A, o único grupo revestido com anticorpo CD34. Ambos os resultados sugerem que as chapas de aço inoxidável 316L foram revestidas com sucesso com VEGF e anticorpo anti-CD34.Conclusão:Nosso estudo desenvolveu um método para revestir simultaneamente VEGF e anti-CD34 de aço inoxidável. Esta pesquisa tem um papel fundamental para a nova estratégia de revestimento.

AbstractIntroduction:Intravascular coronary stenting has been used in the treatment of coronary artery disease (CAD), with a major limitation of in-stent restenosis (ISR). The 316 stainless steel has been widely used for coronary stents. In this study, we developed a novel coating method to reduce ISR by simultaneously coating vascular endothelial growth factor (VEGF) and anti-CD34 antibody on 316L stainless steel.Methods:Round 316L stainless steel sheets in the D-H group were polymerized with compounds generated from condensation reaction of dopamine and heparin using N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide (EDC) and N-hydroxysuccinimide (NHS). Sixteen sheets from the D-H group were further immersed into 1ug/ml VEGF165 and 3mg/ml heparin sodium one after another for 10 times, and named as the D-(H-V)10 group. Eight sheets from the D-(H-V)10 group were coated with anti-CD34 antibody and termed as the D-(H-V)10-A group. Immunofluorescence assay and ELISA were used to evaluate whether the 316L stainless steel disks were successfully coated with VEGF and anti-CD34 antibody.Results:The results of immunofluorescence assay and ELISA showed that VEGF could be detected in the D-(H-V)10 and D-(H-V)10-A group, suggesting the steel sheets were successfully covered with VEGF. Anti-CD34 antibody could only be observed in the D-(H-V)10-A group, which was the only group coated with CD34 antibody. Both results suggested that the 316L stainless steel sheets were successfully coated with VEGF and anti-CD34 antibody.Conclusion:Our study developed a method to simultaneously coat VEGF and anti-CD34 antibody to stainless metal steel. This research serves as a fundamental role for a novel coating strategy.

PURPOSE:To re-evaluated the clinic efficacy of ureteroscopic lithotripsy (URS) and extracorporeal shock wave lithotripsy (ESWL) on ureteral calculi with Cochrane systematic reviews in this paper.METHODS: We searched clinical randomized controlled trials and prospective controlled trials in databases such as Cochrane library, Medline, Springer, Elsevier Science Direct, PubMed. Pooled estimate of risk ratios (RRs), standard mean difference (SMD) with 95% confidence intervals (CIs) were used as measure of effect sizes. Summary effect estimates were also stratified by sample size, study design and study region. The overall effect sizes were derived using a random-effects model or fixed-effects model when appreciated, and meta-analysis were conducted with software RewMan 5.0.RESULTS:The meta-analysis suggested that there were significant differences of post-treatment stone free rate, repeat treatment rate, patients' satisfaction, incidence of postoperative complications, operation time and hospital stays between ESWL treatment cases and URS treatment cases. But in the sample sizes analysis, there were no significant differences of the post-treatment stone free rate and repeat treatment rate when the sample sizes were less than 100.CONCLUSIONS: Compared to the ureteroscopic lithotripsy treatment, extracorporeal shock wave lithotripsy treatment provided a significantly lower post-treatment stone free rate, but it also obviously brought out less postoperative complications, shorter operation time and hospital stays.

Para investigar os efeitos da sanguinarina (SAN) em lesões induzidas em ratos por radiação aguda, 45 ratos foram aleatoriamente divididos em grupo controle, grupo 10 Gy e grupo SAN+10 Gy. Os ratos dos grupos 10 Gy e SAN+10 Gy foram expostos à radiação de raio-X simples com uma dose acumulada de 10 Gy. Aos ratos do grupo SAN+10 Gy administraram-se, intraperitonealmente, 2.5 mg/kg de peso de SAN antes da radiação. Aos 5 dias de exposição à radiação, sacrificaram-se 5 ratos de cada grupo e retiraram-se amostras do intestino delgado, pulmões, baço e fígado para exames histopatológicos. Comparando com o grupo 10 Gy, a doença por radiação foi claramente atrasada e atenuada no grupo SAN+10 Gy. A análise de sobrevivência mostrou diferença significativa entre os dois grupos de radiação (P<0.05) e o tempo de sobrevivência média foi de mais 3 dias no grupo SAN+10 Gy do que no grupo 10 Gy (7.21±0.19 vs 4.20±0.13, P<0.001). Danos induzidos nos órgãos por radiação, baseados em exames histopatológicos, foram reduzidos pelo pré-tratamento com SAN. As pontuações de classificação da patologia Chiu, um índice para os danos intestinais, foi significativamente menor no grupo SAN+10 Gy do que no grupo 10 Gy (2.77±0.48 vs 4.37±0.31, P<0.01). Resultado semelhante foi obtido na pontuação patológica do pulmão (1.67±0.21 vs 2.33±0.38, P<0.01). As nossas descobertas preliminares mostram que SAN protege os animais contra doenças induzidas pela radiação e danos agudos nos órgãos seguidos de morte animal.

To investigate the effects of sanguinarine (SAN) on acute radiation induced injury in mice, 45 mice were randomly divided into control, 10 Gy and SAN+10 Gy groups. Mice in the 10 Gy and SAN+10 Gy groups were exposed to single X-ray radiation with an accumulated dose of 10 Gy. Mice in the SAN+10 Gy group were administered intraperitoneally with 2.5 mg/kg body weight of SAN before radiation. Five days after radiation exposure, 5 mice from each group were sacrificed and samples of the small intestine, lung, spleen and liver were fixed for histopathological examinations. Compared with the 10 Gy group, radiation sickness was obviously delayed or attenuated in the SAN+10 Gy group. Survival analysis showed a significant difference between 2 radiation groups (P<0.05) and mean survival time was 3 days longer in the SAN+10 Gy group than in the 10 Gy group (7.21±0.19 vs. 4.20±0.13, P<0.001). Radiation-induced organ damage, based on histopathological examinations, was decreased by SAN pretreatment. Chiu’s pathology grading scores, which is an index of intestinal damage, was significantly lower in the SAN+10 Gy group than in the 10 Gy group (2.77±0.48 vs. 4.37±0.31, P<0.01). A similar result was obtained in the pathological score of lung (1.67±0.21 vs. 2.33±0.38, P<0.01). Our preliminary findings demonstrated that SAN protects animals against radiation-induced sickness and acute damage to organs and following animal death.

Self-healing of ECC (Engineered Cementitious Composites) subjected to cyclic wetting and drying regimes is investigated in this paper. ECC structures subjected to outdoor environmental conditions such as wind and rain runoff can be simulated by accelerated test method of wetting and drying cycles. Uniaxial tensile tests of ECC M45 and ECC 2.8FA specimen are conducted respectively. It is found that crack width of ECC 2.8FA is around 10 μm with increased amount of fly ash, while the crack width of ECC M45 is around 100 μm. New insights about the microstructure and chemical composition analysis of ECC specimens initially cracked to 2% strain and then self-healed under wet-dry cycles are presented.
