Reliability of anthropometric measurements in the WHO Multicentre Growth Reference Study

Aim: To describe how reliability assessment data in the WHO Multicentre Growth Reference Study (MGRS) were collected and analysed, and to present the results thereof.
Methods: There were two sources of anthropometric data (length, head and arm circumferences, triceps and subscapular skinfolds, and height) for these analyses. Data for constructing the WHO Child Growth Standards, collected in duplicate by observer pairs, were used to calculate inter-observer technical error of measurement (TEM) and the coefficient of reliability. The second source was the anthropometry standardization sessions conducted throughout the data collection period with the aim of identifying and correcting measurement problems. An anthropometry expert visited each site annually to participate in standardization sessions and provide remedial training as required. Inter- and intra-observer TEM, and average bias relative to the expert, were calculated for the standardization data.
Results: TEM estimates for teams compared well with the anthropometry expert. Overall, average bias was within acceptable limits of deviation from the expert, with head circumference having both lowest bias and lowest TEM. Teams tended to underestimate length, height and arm circumference, and to overestimate skinfold measurements. This was likely due to difficulties associated with keeping children fully stretched out and still for length/height measurements and in manipulating soft tissues for the other measurements. Intra- and inter-observer TEMs were comparable, and newborns, infants and older children were measured with equal reliability. The coefficient of reliability was above 95% for all measurements except skinfolds whose R coefficient was 75–93%.
Conclusion: Reliability of the MGRS teams compared well with the study's anthropometry expert and published reliability statistics.     

安神调经针法治疗月经后期探析

心身疾病是当今医学亟待解决的课题.临床上大量月经后期的患者其发病与心理社会因素密切相关,属心身疾病的范畴.据此,笔者提出了月经调节的中医"心脑-肾气-天癸-冲任-胞宫轴"的新模式,并认为它与现代医学"大脑皮层-下丘脑-垂体-卵巢-子宫生殖轴"的神经内分泌调节系统极为相似.在此基础上创立了一套安神调经疗法.通过调整心脑功能,从而调节下丘脑-垂体-性腺轴,促进卵泡发育,治疗月经后期.并以此为突破点,为心身疾病引起的各种妇科病的针灸治疗提供了一种新方法、新思路.     

急性一氧化碳中毒迟发性脑病的动物模型制备研究

目的建立急性一氧化碳(CO)中毒迟发性脑病的动物模型,为其机制研究提供基础.方法体重240～280 g雄性SD大鼠,分次腹腔注射CO染毒制备模型,动态监测尾血碳氧血红蛋白(HbCO)浓度,确定染毒剂量和间隔 .分别于染毒后1、3、7、14、21 d取脑组织,常规制备石蜡病理切片,行HE、Luxol氏坚牢蓝焦油紫及Tunnel原位末端凋亡染色.结果染毒后,大鼠体内血液HbCO迅速升高,使用分次腹腔注射法,大鼠可维持长时间(＞16 h)高HbCO状态(HbCO＞50%) ;病理学检查显示染毒大鼠除急性脑损伤外,还在染毒1～2周后出现脑细胞凋亡、大脑白质脱髓鞘、大脑基底结区变性坏死等二次损伤改变,与临床病理学特点十分吻合.结论本研究建立了一种较为符合迟发性脑病临床特征的动物模型,该模型的建立将可为深入研究急性CO中毒致迟发性脑损伤的机制提供可靠基础.     

手术时机的选择对急性化脓性阑尾炎临床治疗效果的研究

目的探讨手术时机的选择对急性化脓性阑尾炎临床治疗效果的研究。方法选取2017年4月~2018年1月间在我院确诊且行阑尾切除术的急性化脓性阑尾炎患者70例,按照患者发病时间长短分成试验组(发病时间72 h以内)和对照组(发病时间超过72 h),其中试验组患者39例,对照组患者31例,比较两组患者手术时间、术中出血量、术后排气时间、住院时间、住院费用和术后发热时间、抗菌素使用时间及并发症发生率等。结果试验组患者的手术时间、术后排气时间、住院时间明显短于对照组,术中出血量、住院费用也明显少于对照组,差异均有统计学意义(P0.05);试验组患者术后发热时间、术后抗菌素的使用时间都明显短于对照组,差异均有统计学意义(P0.05);试验组术后切口感染2例,腹腔脓肿1例,对照组切口感染4例,腹腔脓肿2例,两组患者均未出现阑尾系膜出血、阑尾残端瘘、阑尾残株炎、肠梗阻等并发症,试验组术后并发症的发生率明显小于对照组,差异有统计学意义(P0.05)。结论即时手术在治疗急性化脓性阑尾炎患者中,手术时间短、肠道功能恢复快、术中损伤小、住院时间短、治疗费用少,同时术后并发症的发生率更低,值得推广。     

The Role Of Electro-Physiological Tests in the Diagnosis of Non-Organic Hearing Loss

Today it is possible, by the use of newly developed tests, to diagnose cases of non-organic hearing loss with reasonable certainty. Having once decided that there may be non-organic elements, it is useful to supplement routine pure-tone and speech audiometry with a neurophysiological test like an ERA by means of which the auditory threshold can be established without the patients subjective judgement. A hearing loss which is apparent by routine pure-tone audiometry, but which is not evident after ERA is almost certainly non-organic, although confirmation of this state of affairs by other reliable tests is advisable. Measurement of the acoustic reflex thresholds and delayed speech feedback tests are both useful in this respect and rarely cause any confusion, except in some cases of true hearing loss in strongly recruiting ears.     

Diagnostic uncertainty and recall bias in chronic low back pain

Patients’ beliefs about the origin of their pain and their cognitive processing of pain-related information have both been shown to be associated with poorer prognosis in low back pain (LBP), but the relationship between specific beliefs and specific cognitive processes is not known. The aim of this study was to examine the relationship between diagnostic uncertainty and recall bias in 2 groups of chronic LBP patients, those who were certain about their diagnosis and those who believed that their pain was due to an undiagnosed problem. Patients (N = 68) endorsed and subsequently recalled pain, illness, depression, and neutral stimuli. They also provided measures of pain, diagnostic status, mood, and disability. Both groups exhibited a recall bias for pain stimuli, but only the group with diagnostic uncertainty also displayed a recall bias for illness-related stimuli. This bias remained after controlling for depression and disability. Sensitivity analyses using grouping by diagnosis/explanation received supported these findings. Higher levels of depression and disability were found in the group with diagnostic uncertainty, but levels of pain intensity did not differ between the groups. Although the methodology does not provide information on causality, the results provide evidence for a relationship between diagnostic uncertainty and recall bias for negative health-related stimuli in chronic LBP patients.
