Neurodevelopmental outcomes of extremely preterm infants: theoretical and epidemiological perspectives to guide shared-care decision-making

Although births below 28 completed weeks' of gestation contribute to less than 1% of all preterm births globally, the impact of extreme prematurity (EPT) on neurodevelopmental outcomes across the life-course is disproportionately large. Higher rates and increased severity of neurodevelopmental impairments (NDIs) are reported among extremely preterm infants (EPIs). Cognitive skills, motor skills (manifesting as cerebral palsy) and vision are most commonly affected, with effects pervasive throughout school, adolescence and early adulthood. In addition, poorer academic outcomes and higher rates of psychiatric morbidity are seen among EPTs. Consistent improvements in EPI survival in recent years has not been matched with improvements in neurodevelopmental outcomes, especially for those born at less than 25 gestational weeks. However, over the last 20 years, several national and cross-national cohort studies have helped advance our understanding of extreme prematurity's developmental and life-course consequences. Here we provide an overview of the key findings from 13 multi-centre cohorts measuring neurodevelopmental outcomes and discuss the theoretical and epidemiological perspectives of NDIs in the context of extreme prematurity to guide communication with families and shared care decision-making.

目的: 探讨关节镜自体骨软骨移植治疗复发性肩关节前脱位的早期疗效。方法: 选取2019年1月至2021年1月行关节镜自体骨软骨移植治疗复发性肩关节前脱位的患者17例，其中男12例，女5例，年龄17~55（32.88±12.33）岁。比较术前、术后6个月、末次随访时Rowe肩关节不稳评分（Rowes rating system for Bankart repair，Rowe），牛津大学肩关节不稳评分（Oxford Shoulder Instability Score，OSIS）及简便肩关节功能测试评分（Simple Shoulder Test，SST）评价肩关节功能，并记录术前、末次随访时肩关节活动度及术中、术后并发症。结果: 17例患者术后均获得随访，时间7~25（18.4±5.4）个月。随访期间患者未出现血管、神经损伤及再脱位发生情况。Rowe评分由术前的（26.2±6.0）分增至术后6个月、末次随访的（74.4±4.0）、（82.4±3.1）分，术后不同时间点与术前比较，差异有统计学意义（P<0.05）；OSIS评分由术前的（37.0±3.6）分增至术后6个月、末次随访的（47.4±2.6）、（52.7±2.6）分，术后不同时间点与术前比较，差异有统计学意义（P<0.05）；SST评分由术前的（6.8±0.7）分增至术后6个月、末次随访的（9.8±0.8）、（11.6±2.6）分，术后不同时间点与术前比较，差异有统计学意义（P<0.05）。末次随访时患者主动体侧外旋和外展外旋活动度较术前明显改善。结论: 关节镜自体关软骨移植治疗关节盂骨折缺损<20%的复发性肩关节前脱位患者可取得令人满意的早期临床疗效及稳定性，是一种可靠且有效的手术。     

外伤性晶状体脱位合并周边隐匿性视网膜病变的临床特征及预后分析

目的观察分析眼球钝挫伤合并外伤性晶状体脱位患者周边隐匿性视网膜病变的临床特点及预后。 方法本研究纳入2013年1月至2020年1月在柳州市人民医院眼科住院诊断为眼球钝挫伤合并外伤性晶状体脱位，并行23G微创玻璃体切割联合白内障摘除手术的72例（72眼）患者。根据裂隙灯和超声生物显微镜（UBM）检查，将患者分为晶状体不全脱位组和全脱位组，详细记录2组患者的术中周边视网膜病变情况，并分析其临床特征及疗效。 结果眼球钝挫伤合并外伤性晶状体脱位患者中有周边隐匿性视网膜病变的占72.22%，其中晶状体不全脱位组发生率高达80.95%，显著大于晶状体全脱位组的60.00%（P＜0.05）。2组患者的周边隐匿性视网膜病变均以隐匿性视网膜裂孔、变性和出血为最常见。所有患者术后视网膜情况稳定，视力预后较好。 结论眼球钝挫伤合并外伤性晶状体脱位患者常出现周边隐匿性视网膜病变，最常见的是视网膜裂孔、出血、变性。23G微创玻璃体切割联合白内障摘除手术是有效治疗手段，具有创伤小、并发症少的优势。     

抗阻训练联合家居康复护理在发育性髋关节不良中的应用

目的探究与分析Thera-Band渐进抗阻训练联合家居康复护理对发育性髋关节不良术后患儿髋关节功能的促进效果。方法选取医院自2016年12月—2018年12月收治的发育性髋关节不良手术患儿68例作为研究对象,采用随机数字表法分为对照组与观察组,每组各34例,两组均给予常规护理,对照组给予Thera-Band渐进抗阻训练,观察组在对照组基础上给予家居康复护理,对比两组患儿术后不同时间点Harris评分以及患儿家属发育性髋关节不良的健康教育知晓情况。结果两组患儿出院后1个月、出院后3个月的Harris评分明显高于出院时,观察组较对照组相比Harris评分改善更加显著,组间差异具有统计学意义(P<0.05)。观察组与对照组相比家属发育性髋关节不良情况健康教育知晓评分较高,组间差异具有统计学意义(P<0.05)。结论Thera-Band渐进抗阻训练联合家居康复护理进一步的提高了患儿髋关节功能功能,也在护理工作中促进提高了患儿家属对发育性髋关节不良的健康教育知晓情况,更好的发挥了辅助效果。     

Changes in knee extensor strengths before and after medial patellofemoral ligament reconstruction

Objective: Quadriceps dysfunction has been suggested as a complication after medial patellofemoral ligament (MPFL) reconstruction. The purpose of this study was to investigate changes in knee extensor strength before and after MPFL reconstruction.

Methods: Twenty patients who underwent MPFL reconstruction for unilateral recurrent patellar dislocation (18 females and 2 males; mean age 20.8 ± 7.6 years) were examined. The peak isometric torque at 60° and 90° of knee flexion and isokinetic knee extensor strength at speeds of 60°/s and 90°/s in operated and non-operated legs were measured using a dynamometer preoperatively and 6 months, 1 year, and 2 years postoperatively. The following parameters were evaluated: (1) body weight-adjusted muscle strength, (2) improvement index (post-/preoperative value × 100) (%), and (3) extensor strength ratio (operated/non-operated value × 100) (%).

Results: The mean knee extensor strength in both operated and non-operated legs significantly increased 2 years after surgery compared with that before surgery. At 2 years postoperatively, the improvement indexes of the isometric knee extensor strength at 60° and 90° and of the isokinetic knee extensor strength at 60°/s and 90°/s were 237%, 192%, 318%, and 186%, respectively, in the operated legs and 144%, 124%, 140%, and 140%, respectively, in the non-operated legs. At 2 years postoperatively, the mean isometric knee extensor strength ratios at 60° and 90° and the isokinetic knee extensor strength ratios at 60°/s and 180°/s were 81%, 84%, 81%, and 82%, respectively.

Conclusions: Knee extensor strength was improved in most patients after MPFL reconstruction, at least compared with that before surgery, although an approximately 20% deficit against the non-operated legs remained even 2 years after surgery.     

Profiles of caregiving behaviors among children and adolescents with perinatally acquired HIV

Although parenting behaviors are widely considered an important factor in the adjustment of children and adolescents with chronic physical health needs, few studies have addressed this topic as it pertains to youth with perinatally-acquired human immunodeficiency virus (PHIV). We examined profiles of child-centeredness, control through guilt, consistent discipline, and detachment, and whether these profiles differed in terms of parent- and youth-reported psychiatric disorder symptoms in a cohort of HIV infected youth (N?=?314). Latent profile analyses of caregiving behaviors were conducted separately for children (6–12 years) and adolescents (13–18 years). Two profiles were identified among children: (a) moderate caregiving (87%, n?=?130) and (b) high detachment caregiving (13%, n?=?19), and three profiles were identified among adolescents: (a) moderate caregiving (55%, n?=?88), (b) high detachment caregiving (19%, n?=?30), and (c) high control through guilt caregiving (26%, n?=?42). The high detachment and high control through guilt caregiving profiles displayed higher levels of parent-and youth-reported symptoms than the moderate caregiving profile. These findings suggest that caregiver behaviors of PHIV youth vary as a function of children’s developmental period and differ in terms of youth psychological symptoms.
