Completion of a worldwide reference panel of samples for an ancestry informative Indel assay

The use of ancestry informative markers (AIMs) in forensic analysis is of considerable utility since ancestry inference can progress an investigation when no identification has been made of DNA from the crime-scene. Short-amplicon markers, including insertion deletion polymorphisms, are particularly useful in forensic analysis due to their mutational stability, capacity to amplify degraded samples and straightforward amplification technique. In this study we report the completion of H952 HGDP–CEPH panel genotyping with a set of 46 AIM-Indels. The study adds Central South Asian and Middle Eastern population data, allowing a comparison of patterns of variation in Eurasia for these markers, in order to enhance their use in forensic analyses, particularly when combined with sets of ancestry informative SNPs. Ancestry analysis using principal component analysis and Bayesian methods indicates that a proportion of classification error occurs with European–Middle East population comparisons, but the 46 AIM-Indels have the capability to differentiate six major population groups when European–Central South Asian comparisons are made. These findings have relevance for forensic ancestry analyses in countries where South Asians form much of the demographic profile, including the UK, USA and South Africa. A novel third allele detected in MID-548 was characterized – despite a low frequency in the HGDP–CEPH panel samples, it appears confined to Central South Asian populations, increasing the ability to differentiate this population group. The H952 data set was implemented in a new open access SPSmart frequency browser – forInDel: Forensic Indel browser.     

中老年2型糖尿病患者睡眠质量与肌少症关系的研究

目的 探讨中老年2型糖尿病患者睡眠质量与肌少症之间的关系，旨在为肌少症的预防和干预提供相关理论参考。方法 采用便利抽样法，对泸州市3所三甲综合医院的内分泌科收治的325名中老年2型糖尿病患者使用匹兹堡睡眠指数量表、肌少症筛查量表等进行问卷调查，采用非条件logistic回归分析受试者睡眠质量与肌少症关系。结果 在325名受试者中，筛查为肌少症的人数为78人(24%)，睡眠质量差的受试者为168人(51.7%)；肌少症总分与睡眠质量得分呈正相关(r=0.246,P＜0.001)；未纳入混杂因素前睡眠质量是受试者筛查为肌少症的危险因素(粗OR=1.11,95%CI:1.052~1.172,P＜0.01）；在该模型基础上，自变量增加了性别、年龄段、职业等变量后睡眠质量仍然是受试者筛查为肌少症的危险因素(调整后OR=1.083,95%CI:1.018~1.152,P＜0.001)。结论 睡眠质量得分是中老年2型糖尿病患者筛查为肌少症的独立危险因素，应尤其重视睡眠质量差的中老年2型糖尿病患者肌少症的预防与诊断。     

Evaluation of postoperative patient satisfaction after covering the nasal dorsum with upper lateral cartilage: “upper lateral closing”

Introduction

Following nasal hump removal during septorhinoplasty, the middle vault should be reconstructed to avoid functional and esthetic problems. Middle vault reconstruction, however, may result in widening of the middle vault and may need a camouflage graft to cover dorsal irregularities.

Inhibited symptoms of Reactive Attachment Disorder: links with working models of significant others and the self

ABSTRACT

To better understand Reactive Attachment Disorder (RAD), the current study tested whether emotionally and behaviorally disordered children with versus without RAD differ with regard to the quality of their interpersonal behavior during interactions with teachers and with regard to their representations of self and others. Therefore, 77 children were screened for RAD symptoms and 22 likely cases of inhibited RAD were identified. To measure quality of the interactions with teachers, we observed children’s trust and positive affect in dyadic interactions with teachers. For the representations of others, we measured self-reported trust in parents and teachers. For the representations of the self, two self-esteem assessments were individually administered. Results showed that, compared to children with other emotional and behavior disorders, RAD children’s behavior reflected less trust in their teachers. At the level of representations, children reported less trust in teacher care. Instead, no links were found with self-report measures focusing on representations of parents and of self. These findings will be discussed in light of the ongoing discussion about whether or not attachment disorder and insecure attachment are associated concepts.     

Mitochondrial DNA control region variation in Lebanon,Jordan, and Bahrain

This study investigated the mitochondrial DNA (mtDNA) control region variation in Middle Eastern populations (610 individuals from Lebanon, Jordan and the Kingdom of Bahrain) for which population data are scarce. FST comparison among populations revealed that there are significant differences in mtDNA distributions between Bahrain and the two other populations, while Lebanon and Jordan showed no significant differences. This was also reflected by the distribution of the observed lineages that differed prominently between Bahrain and the other two investigated populations. Jordan and Lebanon fit the hitherto known genetic results of the Levant population. Data are available via EMPOP (https://empop.online) and GenBank.

The effect of glucose tolerance test on fetoplacental circulation

ObjectiveAcute hyperglycemia affects the fetoplacental circulation. This study aims to investigate the possible effect of acute hyperglycemia induced by 50 g oral glucose tolerance test (OGTT) on fetoplacental circulation in women between 24 and 28 weeks of gestation.Materials and methodsBetween January 2019 and April 2019, a total of 29 women who were between 24 and 28 weeks of gestation with a singleton gestation and were in low-risk group were included in this prospective study. All patients underwent fetal biometric measurements using ultrasonography (USG) and were administered 50 g OGTT. Before and 1 h after the test, Doppler USG was used to measure uterine artery, umbilical artery (UA), middle cerebral artery (MCA), pulsatility index (PI), resistance index (RI), and systolic/diastolic (S/D) ratio. The cerebroplacental ratio (CPR) was calculated as the ratio of the MCA-PI/UA-PI.ResultsThere was a decline in the MCA-RI (p = 0.008) and UA-PI (p = 0.021) at 1 h after the administration of 50 g OGTT. Z-scores of the mean UA-PI, MCA-PI, and CPR were calculated and a statistically significant increase in the Z-scores of the mean UA-PI was observed (p = 0.028).ConclusionOur study results show that acute hyperglycemia induced by OGTT significantly increases the Z-scores of the UA-PI, affecting the fetoplacental circulation.     

Structural Factors of the Middle East Respiratory Syndrome Coronavirus Outbreak as a Public Health Crisis in Korea and Future Response Strategies

The recent Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak has originated from a failure in the national quarantine system in the Republic of Korea as most basic role of protecting the safety and lives of its citizens. Furthermore, a number of the Korean healthcare system’s weaknesses seem to have been completely exposed. The MERS-CoV outbreak can be considered a typical public health crisis in that the public was not only greatly terrorized by the actual fear of the disease, but also experienced a great impact to their daily lives, all in a short period of time. Preparedness for and an appropriate response to a public health crisis require comprehensive systematic public healthcare measures to address risks comprehensively with an all-hazards approach. Consequently, discussion regarding establishment of post-MERS-CoV improvement measures must focus on the total reform of the national quarantine system and strengthening of the public health infrastructure. In addition, the Korea Centers for Disease Control and Prevention must implement specific strategies of action including taking on the role of “control tower” in a public health emergency, training of Field Epidemic Intelligence Service officers, establishment of collaborative governance between central and local governments for infection prevention and control, strengthening the roles and capabilities of community-based public hospitals, and development of nationwide crisis communication methods.
