Efeitos Terapêuticos da Tripla Antiagregação Plaquetária em Pacientes Femininas Idosas com Diabetes e Infarto Agudo do Miocárdio

BackgroundDual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI).ObjectiveThe 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).MethodsWe 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.ResultsCompared 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).ConclusionTAPT 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)     

Immunogenicity of next-generation HPV vaccines in non-human primates: Measles-vectored HPV vaccine versus Pichia pastoris recombinant protein vaccine

Human papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide. HPVs are oncogenic small double-stranded DNA viruses that are the primary causal agent of cervical cancer and other types of cancers, including in the anus, oropharynx, vagina, vulva, and penis. Prophylactic vaccination against HPV is an attractive strategy for preventing cervical cancer and some other types of cancers. However, there are few safe and effective vaccines against HPV infections. Current first-generation commercial HPV vaccines are expensive to produce and deliver.The goal of this study was to develop an alternate potent HPV recombinant L1-based vaccines by producing HPV virus-like particles into a vaccine that is currently used worldwide. Live attenuated measles virus (MV) vaccines have a well-established safety and efficacy record, and recombinant MV (rMV) produced by reverse genetics may be useful for generating candidate HPV vaccines to meet the needs of the developing world.We studied in non-human primate rMV-vectored HPV vaccine in parallel with a classical alum adjuvant recombinant HPV16L1 and 18L1 protein vaccine produced in Pichia pastoris. A combined prime-boost approach using both vaccines was evaluated, as well as immune interference due to pre-existing immunity against the MV.The humoral immune response induced by the MV, Pichia-expressed vaccine, and their combination as priming and boosting approaches was found to elicit HPV16L1 and 18L1 specific total IgG and neutralizing antibody titres. Pre-existing antibodies against measles did not prevent the immune response against HPV16L1 and 18L1.     

手术治疗结节性甲状腺肿合并甲状腺癌的临床效果

目的:分析手术治疗结节性甲状腺肿合并甲状腺癌的临床效果。方法:从2017年3月~2019年3月期间到我院接受治疗的结节性甲状腺肿合并甲状腺癌患者中选出60例完成此次研究,60例患者全部接受手术治疗,经1年的随访后对比两组患者接受治疗前后的生活质量变化情况及治疗效果。结果:接受治疗后患者的心理、身体、物质生活、社会关系等多项生活质量指标均优于治疗前,治疗前后的数据对比存在明显差异(P<0.05)。所有患者接受治疗后均为表现出较为明显的不良反应,其治疗存在较高安全性,总治疗有效率为87.50%(55/60)。结论:帮助结节性甲状腺肿合并甲状腺癌患者选择合理的手术方式,能够提高临床治疗效果,减少并发症。     

不同健康状况的中老年人社会资本量表的信度及效度评价

目的 评价中老年人社会资本量表的信效度，探索其在不同健康状况的中老年人群间的区分度。方法 针对已编制的中老年人社会资本量表，采用多阶段分层随机抽样方法，在四川省成都市及泸州市共抽取1 367名50岁及以上中老年居民进行问卷调查。运用Cronbach’s α系数、Pearson相关系数、t检验、探索性因子分析等方法评价量表的信度和效度。结果 1 367名中老年调查对象的社会资本量表总Cronbach’s α系数为0.67，各维度条目与总分的相关系数在0.30～0.79之间，具有良好的信度；探索性因子分析表明，14个条目提取出5个特征根大于1的因子，累积方差贡献率为68.84%；现患慢性疾病的中老年病例组人群的个人社会资本得分、家庭社会资本得分、社团社会资本得分、社区社会资本得分及社会资本总得分均低于未患病的对照人群组，宏观社会资本得分高于对照人群组，且差异均有统计学意义 (均 P＜0.01)，提示该量表具有较好的区分度。结论 中老年人社会资本量表具有较好的信度和效度，且对不同健康状况的50岁及以上中老年人中有较好的区分度。     

西药联合穴位贴敷中西医结合治疗复治肺结核疗效观察

目的评价西药联合穴位贴敷中西医结合治疗复治肺结核的临床疗效。方法选择本院2017年1月～2018年1月收治的60例复治肺结核患者进行分组研究,全部患者根据治疗方法不同随机分为两组,每组各30例。两组均采取西药进行治疗,采用2HRZE/6HRZ标准化疗方案,实验组同时联合穴位贴敷中西医结合进行治疗,治疗后对比分析两组病灶吸收情况及两组临床症状改善情况。结果实验组病灶恶化9例,其病灶显著吸收率达50.0%,总有效率达70.0%,对照组病灶恶化6例,不变5例,其病灶显著吸收率达33.3%,总有效率达63.3%,两组病灶吸收总有效率组间比较,差异具有显著性(P0.05);实验组的疗效指数治疗6个月后显著高于对照组,组间比较,差异具有显著性(P0.05)。结论西药联合穴位贴敷中西医结合治疗复治肺结核疗效确切,可以显著促进病灶吸收,改善临床症状,安全性好,且还可以扶助人体正气,提高机体免疫力,调节全身状态,以达到治疗目的,是治疗复治肺结核的有效方法之一,值得临床广泛推广和应用。
