Can a pragmatic responsive feeding scale be developed and applied globally?

Responsive feeding (RF) has been recognized as necessary to prevent all forms of malnutrition including stunting and childhood obesity. Specific RF guidelines have been developed, but it is unclear how RF behaviours can be monitored systematically. Therefore, developing valid and reliable abbreviated and pragmatic RF scales is an important global priority. This is challenging, as RF is a construct with multiple dimensions including recognizing and responding to hunger and satiety cues, providing a nurturing environment during feeding episodes, and understanding how feeding needs evolve as a function of the developmental stage of the young child. Further, RF is embedded within the responsive parenting framework that in addition to RF includes sleep, soothing and play routines and the interconnections between them. A recent pioneer study conducted in a rural area of Cambodia validated an 8‐item RF scale through direct feeding observations of 6‐ to 23‐month‐old infants at home, as part of two cross‐sectional surveys conducted before and after a complementary feeding intervention. It is important for similar research to be conducted elsewhere to find out if it is possible or not to develop a core RF scale that is valid and reliable and that has adequate specificity and sensitivity for application in community studies and population surveys globally. As highlighted in this article, different definitions of RF have been used in the field; thus, it is important to reach consensus on a single definition to help move this research area forward.     

解剖锁定钢板联合同种异体腓骨治疗肱骨近端骨折疗效的Meta分析

文题释义：肱骨近端骨折：肱骨近端包括肱骨头及大结节、小结节，中老年人骨质疏松及低能量损伤可导致肱骨近端骨折。 同种异体腓骨：取自于人体异体，经过加工处理，去除其免疫原性，保留其骨性结构，可用于移植修复骨缺损，起到支撑作用。 背景：肱骨近端骨折是临床常见骨折，但对肱骨近端内侧柱缺乏支撑的骨折目前仍是治疗难点，并发症常见，失败率较高。 目的：比较解剖锁定钢板联合同种异体腓骨与单纯解剖锁定钢板治疗肱骨近端骨折的疗效。 方法：使用计算机检索PubMed、Embase、Cochrane Library、Google Scholar、中国知网、万方、维普数据库，检索时间均从建库到2020年2月。检索国内外关于对比研究解剖锁定钢板联合同种异体腓骨与单纯解剖锁定钢板治疗肱骨近端骨折疗效的文献。2名研究员根据纳入和排除标准分别独立筛选文献，提取数据，评估文献中的偏倚风险。纳入12篇相关文献使用RevMan 5.2软件将以下指标进行Meta分析，包括影像学数据、功能评分和并发症。结果与结论：①通过文献检索、根据纳入和排除标准，12篇文献纳入研究，其中11篇为回顾性队列研究，1篇为随机对照研究；纳入研究文献质量高，但GRADE证据质量级别较低。②共纳入958例患者，其中解剖锁定钢板联合同种异体腓骨组411例，单纯解剖锁定钢板组547例；③Meta分析结果显示，解剖锁定钢板联合同种异体腓骨组术后1年肱骨头高度差值(MD=-2.40，95%CI：-2.49至-2.31)、颈干角差值(MD= -6.14，95%CI：-6.62至-5.67)、目测类比评分(MD=-0.22，95%CI：-0.35至-0.08)、肩关节功能评分(MD=4.12，95%CI：2.18-6.06)，上肢伤残评分(MD=-10.32，95%CI：-13.44至-7.19)、术后2年的目测类比评分(MD=-0.37，95%CI：-0.55至-0.19)、肩关节功能评分(MD=5.07，95%CI：2.86-7.27)、总体并发症(OR=0.31，95%CI：0.20-0.48)及肱骨头螺钉切出(OR=0.25，95%CI：0.11-0.55)均明显优于单纯解剖锁定钢板组(P < 0.05)，肱骨头坏死(OR=0.94，95%CI：0.47-1.88)，两组间差异无显著性意义(P > 0.05)；④因此，较弱的证据提示，肱骨近端解剖锁定钢板联合同种异体腓骨治疗肱骨近端骨折的短期疗效优于解剖锁定钢板，可减少并发症的发生，促进功能恢复。ORCID: 0000-0002-8486-3932(阳运康) 中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程

Torsion and linear accuracy in intraoral scans obtained with different scanning principles

PurposeFew investigations have examined the production of single restorations using intraoral scanners (IOS). Data on full-arch scans are rare, and data regarding torsion within the entire arch are very sparsely reported. Therefore, the aim of this study was to examine the deviations of torsion and linear distances in full-arch scans of three IOS based on different scanning principles.MethodsA cobalt-chrome-molybdenum alloy master model (CCMM) with four hemispheres was fabricated by laser sintering. The CCMM was digitized using a laboratory scanner (ATOS-Core/GOM) and scanned with three IOS (Omnicam/Sirona(OC); True Definition/3M(TD); TriosII/Cara-Version/Kulzer(TR)). All scan data were exported in a standard STL-file format and were analyzed with GOM Inspect software (V7.5/GOM). Torsion between the right and left side of the arch and linear accuracy (trueness and precision) were evaluated. After normality was confirmed, all data were subjected to parametric statistical analyses.ResultsThe torsion ranged from 0.07 ± 0.03°(OC) to 0.29 ± 0.14°(TD). Pairwise comparisons showed significant differences between the OC and TD scanners and between the TR and TD scanners. The linear distances ranged from 6 ± 5 μm(OC) to 298 ± 317 μm(TD). Significant differences were observed among all investigated IOS (p = 0.05).ConclusionsAlthough the highest torsion was observed for the TD scanner, it is still not clear whether the differences between the IOS are related to the scanning principle or to the scanning algorithm. Due to the high clinical relevance of full-arch restorations, future studies should consider torsion. Regarding linear accuracy, no general difference related to the scanning principles of the IOSs was observed.     

郭军教授治疗特发性男性不育症的经验

男性不育症中,精液分析多种参数异常且无法找到明确病因的称为特发性男性不育症,其发病率不断提高,给国内甚至全球范围内家庭带来精神及经济负担。由于病因不明确,目前现代医学尚无有效治疗方法。传统中医药通过辨证论治在治疗特发性男性不育症时具有优势,郭军教授认为该病以肾脾两虚为本,为体内湿热形成奠定基础,患者久病无子嗣,肝气不畅则郁结,气血津液运行不通则夹血瘀湿热等有形实邪,另外怪病多痰。故对于特发性男性不育症,治法注重补泻兼施,扶正祛邪,补益脾肾为主,对于湿热、痰湿、瘀血则清热祛湿化痰,活血化瘀等,并举验案1例。     

Colon and rectal cancer risk after bariatric surgery in a multicountry Nordic cohort study

Obesity is a risk factor for colorectal cancer. Yet, some research indicates that weight-reducing bariatric surgery also increases colorectal cancer risk. Our study was undertaken because current evidence examining bariatric surgery and risk of colorectal cancer is limited and inconsistent. This population-based cohort study included adults with a documented obesity diagnosis in Denmark, Finland, Iceland, Norway or Sweden in 1980–2015. The incidence of colorectal cancer in participants with obesity who had and had not undergone bariatric surgery was compared to the incidence in the corresponding background population by calculating standardized incidence ratios (SIR) with 95% confidence intervals (CI). Additionally, operated and nonoperated participants with obesity were compared using multivariable Cox regression, providing hazard ratios (HR) with 95% CIs adjusted for confounders. Among 502,772 cohort participants with an obesity diagnosis, 49,931(9.9%) underwent bariatric surgery. The overall SIR of colon cancer was increased after bariatric surgery (SIR 1.56; 95% CI 1.28–1.88), with higher SIRs ≥10 years postsurgery. The overall HR of colon cancer in operated compared to nonoperated participants was 1.13 (95% CI 0.92–1.39) and 1.55 (95% CI 1.04–2.31) 10–14 years after bariatric surgery. Bariatric surgery did not significantly increase the risk of rectal cancer (SIR 1.14, 95% CI 0.83–1.52; HR 1.08, 95% CI 0.79–1.49), but the risk estimates increased with longer follow-up periods. Our study suggests that bariatric surgery is associated with an increased risk of colon cancer, while the support for an increased risk of rectal cancer was weaker.
