小儿弱视采用多媒体训练与传统遮盖治疗的效果对比

目的分析小儿弱视采用多媒体训练与传统遮盖治疗的效果。方法 100例小儿弱视患儿,采用计算机随机法分为传统组和多媒体组,每组50例。传统组患儿采用传统遮盖治疗,多媒体组患儿采用多媒体训练。比较两组患儿治疗前后立体视觉情况、视力水平及治疗效果。结果多媒体组患儿治疗总有效率为94.00%(47/50),高于传统组的80.00%(40/50),差异具有统计学意义(P<0.05)。治疗后,多媒体组患儿立体视觉正常率为90.00%(45/50),高于传统组的74.00%(37/50),差异具有统计学意义(P<0.05)。治疗后,两组患儿视力水平均高于本组治疗前,且多媒体组患儿视力水平(0.93±0.12)高于传统组的(0.84±0.12),差异具有统计学意义(P<0.05)。结论小儿弱视采用多媒体训练与传统遮盖治疗的效果存在差异,多媒体训练可更好地改善患儿视力,值得推广和应用。     

全国2015-2020年精神科医师转岗培训状况

目的:调查全国精神科医师转岗培训情况,为优化精神科医师转岗培训和制定精神卫生人才培养体系建设提供参考。方法:设计精神科医师转岗培训调查问卷,调查全国31个省(自治区、直辖市)和新疆生产建设兵团2015-2020年转岗培训情况。采用描述性分析方法,对全国精神科医师转岗培训和培训区县覆盖等情况进行分析;采用χ~2检验比较东中西部地区转岗医师中已提供精神科诊疗服务情况。结果:全国共13 388人完成精神科医师转岗培训,9923人变更或加注了精神科执业资质,6538人已提供精神科诊疗服务,无精神卫生资源空白区县数减少85.1%。结论:转岗培训短期内缓解了精神卫生人才紧缺现状,提高了精神卫生服务可及性。     

Inspiratory muscle training improves performance of a repeated sprints ability test in professional soccer players

BackgroundInspiratory muscle training (IMT) is an important method of attenuating both respiratory and peripheral effort perceptions, consequently improving neuromuscular performance and resulting in greater improvements in exercise capacity than exercise training alone.ObjectiveThe aim of this study was to investigate the effects of IMT on exercise tolerance, repeated sprint ability (RSA) performance, maximal inspiratory pressure (MIP), and peak inspiratory flow (PIF) in a cohort of professional male soccer players.MethodsTwenty-two healthy male professional soccer players (18.3 ± 1.4 years; 174.5 ± 6.1 cm; 70.5 kg ± 4.6 kg; body fat 10.1 ± 4.2%) from a club in the Brazilian first division soccer league participated in this study. IMT consisted of 15 and 30 self-paced inspiratory breaths (each to 50% maximal static inspiratory pressure [P₀]) in the 1-and 2-week intervention period, respectively. IMT was performed prior to soccer training (1 sets.d⁻¹; 6 d.wk⁻¹) with repeated sprint ability (RSA) assessed pre- and post- the 2-week period of IMT.ResultsStatistical analyses identified a significant (p < 0.001) decrease in sprint time post-IMT. Additionally, RSA_best, RSA_mean, total sprint time and percentage of RSA performance decrement (RSA _{% dec}) also showed significant decreases (p < 0.0001) post-IMT. Additional measures including MIP and PIF were also significantly elevated (p < 0.0002) following the 2-week period of IMT.ConclusionIn conclusion, our results raise two important issues. Firstly, IMT demonstrated enhanced inspiratory muscle strength in professional soccer players. Secondly, this increase in inspiratory muscle efficiency led to a decrease in sprint time and improved exercise tolerance. We recommend that a standard training protocol be developed and tested in an experimental and control group with a large representative sample.
