When Fryn met Edward: Two rare syndromes in a single patient

A neonate born at our centre was diagnosed as Fryns Syndrome ie congenital diaphragmatic hernia with facial dysmorphism and distal limb anomalies, which is a rare disorder with only a few hundred cases reported till date.With high clinical index of suspicion and further evaluation, the diagnosis was confirmed. The baby was initially stabilized and later underwent repair of the diaphragmatic hernia. Despite best measures, the baby could not be salvaged. When severe, this can be lethal and diagnosis can only be made after autopsy. However, with early suspicion, better modalities of investigations available and improved NICU care, these babies can be salvaged. We report a case of Fryns Syndrome who was incidentally found to have Edward Syndrome as well. Such an extremely rare combination is yet to be reported in medical literature.Also with updated genetic studies, better diagnostics and treatment options coming up in future, there are chances to improve the survivability of these babies. It is prudent to document all such cases to aid in better understanding of the disease process.     

基于代谢组学分析的18-三体妊娠羊水差异代谢物

摘要:目的通过 非靶向代谢组学方法分析18-三体( trisomy 18,T18) 妊娠母体羊水样本,探索其差异代谢物。方法采用病 例-对照研究,以8例18-三体妊娠母体羊水样本为病例组,40例正常胎儿母体羊水样本为对照组,采用气相色谱飞行时间质 谱技术( GC-T0F/MS)检测两组羊水样本。采用主成分分析(PCA)和正交偏最小二乘法判别分析(OPIS-DA)模型分析代谢谱 差异,通过单维统计分析寻找差异代谢物。结果PCA 和OPLS-DA模型分析均显示病例组与对照组之间无明显分离趋势。 通过单维分析在两组间共发现5种差异代谢物,分别为甘油醛、葡萄糖酸、硫酸吲哚酚.磷酸盐和泛酸(P<0.05)。结论羊水 代谢组学证实18-三体妊娠存在多种代谢物水平的差异,为疾病的发生机制的探索提供了更多研究思路。     

Updates in therapeutic drug monitoring in inflammatory bowel disease

Biologics and immunomodulators (IMM) are generally considered the most effective therapies for the treatment of ulcerative colitis and Crohn’s disease. However, despite the efficacy of these therapies, many patients either have a primary lack of response or a secondary loss of response to these medications. Therapeutic drug monitoring (TDM) is a systematic approach to managing such patients. In this review, we summarize the latest data on TDM, including reactive and proactive TDM, in patients with inflammatory bowel disease on biologics and/or IMM.     

Does different cranial suture synostosis influence orbit volume and morphology in Apert syndrome?

This study was performed to compare the orbital and peri-orbital morphological variations in Apert syndrome patients with different cranial vault suture synostosis, so as to provide an anatomic basis for individualized surgical planning. Computed tomography scans of 57 unoperated Apert syndrome patients and 59 controls were subgrouped as follows: type I, bilateral coronal synostosis; type II, pansynostosis; type III, perpendicular combinations of cranial vault suture synostoses. Orbit bony cavity volume was significantly reduced in type I and type II, by 19% (P < 0.001) and 24% (P < 0.001), respectively. However, the reduction of orbital cavity volume in type III did not reach statistical significance. Globe volume projection beyond the orbital rim, however, increased by 76% (P < 0.001) in type III, versus an increase of 54% (P < 0.001) in type I and 53% (P < 0.001) in type II, due to different ethmoid and sphenoid bone malformations. Maxillary bone volume was only significantly reduced in type I bicoronal synostosis (by 24%, P = 0.048). Both type I and type II developed relatively less zygoma and sphenoid bone volume. Different cranial vault suture synostoses have varied influence on peri-orbital development in Apert syndrome. Instead of mitigating the abnormalities resulting from bicoronal synostosis in type I, additional midline suture synostosis worsens the exorbitism due to a more misshaped ethmoid.     

基于贵州省人群队列的代谢综合征发病风险和影响因素分析

目的 探讨代谢综合征（MS）的发病风险和影响因素，为预防MS提供科学依据。方法 采取多阶段整群抽样方法，于2010年建立贵州省人群队列，排除基线MS患者后，共有7 136人进入MS随访队列，收集队列人群基线社会人口学信息、生活行为方式和生理指标，并于2016—2020年进行随访，最终纳入4 754人进行分析。采用COX比例风险模型分析MS的发病风险及其影响因素的HR（95% CI），并计算影响因素的人群归因危险度（PAF%）。同时根据基线人群的MS组分得分建立亚队列，分析亚队列人群MS的影响因素。结果 队列人群累计随访33 424.18人年，中位随访6.57年，新发MS 963人，MS发病密度为28.81/1 000人年。COX回归分析结果显示:年龄45～59岁（HR = 1.53，95%CI:1.32～1.77）、年龄≥60岁（HR = 1.53，95%CI:1.27～1.86）、城市（HR = 1.71，95%CI:1.47～1.99）、吸烟（HR = 1.22，95%CI:1.01～1.48）、每日油摄入＞30 g（HR = 1.16，95%CI:1.01～1.34）、每日盐摄＞6 g（HR = 1.22，95%CI:1.05～1.42）、静态时间≥4 h/d（HR = 1.16，95%CI:1.02～1.32）、超重（HR = 1.66，95%CI:1.44～1.92）、肥胖（HR = 2.27，95%CI:1.71～3.02）、静息心率70～80次/min（HR = 1.32，95%CI:1.11～1.58）和 ＞80次/min（HR = 1.28，95%CI:1.07～1.54)是MS的危险因素，其PAF%分别为17.47%、11.32%、19.52%、5.89%、11.33%、13.66%、7.01%、12.91%、5.30%、17.68%、13.92%，文化程度升高（HR = 0.75，95%CI:0.68～0.83）和饮茶行为（HR = 0.82，95%CI:0.71～0.95）是MS的保护因素，其PAF%分别为16.21%和6.97%。亚队列研究结果与总体结果相似。结论 不健康的生活方式和超重、肥胖、静息心率升高是MS的影响因素，应将中老年人和城市居民作为预防MS的重点人群，采取相应措施控制烟草消费、油盐摄入，维持正常体重和适当心率，提高人群知识水平，保持饮茶行为，预防MS发生。     

Examining Acute Coronary Syndrome Across Ethnicity,Sex, and Age

Acute coronary syndrome (ACS) remains one of the leading causes of death in the United States. With its heightened prevalence, considerable variabilities in the disease process exist across ethnicities, sex, and age. This creates substantial disparities in the recognition and management of ACS, which consequently contributes to poor outcomes. It is of utmost importance that nurse practitioners remain vigilant, cognizant, and maintain a high index of suspicion to accurately identify ACS presentations and thus efficaciously intervene to successfully manage the disease process.     

Parenchymal calcification is associated with the neurological prognosis in patients with congenital rubella syndrome

Congenital rubella syndrome (CRS) results from maternal rubella virus infection in early pregnancy. Abnormal neuroimaging findings have been analyzed in a small number of CRS patients in the past; however, their clinical significance has been poorly addressed. Therefore, we have investigated the neuroimaging findings of 31 patients with CRS from previous studies. The most common finding was parenchymal calcification, which was observed in 18 of 31 patients (58.1%). A multivariable logistic regression model showed that it was associated with psychomotor or mental retardation (p = 0.018), suggesting that parenchymal calcification in CRS could be a prognostic factor.
