Attachment to Caregivers and Type 1 Diabetes in Children

Attachment is a behavioral and physiological system, which enables individual’s dynamic adaptation to its environment. Attachment develops in close interaction between an infant and his/her mother, plays an important role in the development of the infant’s brain, and influences the quality of interpersonal relationships throughout life.Security of attachment is believed to influence individual response to stress, exposing insecurely organized individuals to deregulated autonomic nervous system and exaggerated hypothalamic-pituitary-adrenal activity, which, in turn, produces increased and prolonged exposure to stress-hormones. Such stress responses may have considerable implications for the development of diverse health-risk conditions, such as insulin resistance and hyperlipidemia, shown by numerous studies.Although the mechanisms are not yet fully understood, there is compelling evidence highlighting the role of psychological stress in the development of type 1 diabetes (T1D). One of the possible contributing factors for the development of T1D may be the influence of attachment security on individual stress reactivity. Thus, the suggestion is that insecurely attached individuals are more prone to experience increased and prolonged influence of stress hormones and other mechanisms causing pancreatic beta-cell destruction.The present paper opens with a short overview of the field of attachment in children, the principal attachment classifications and their historic development, describes the influence of attachment security on individual stress-reactivity and the role of the latter in the development of T1D. Following is a review of recent literature on the attachment in patients with T1D with a conclusion of a proposed role of attachment organization in the etiology of T1D.     

Secondary haemophagocytic lymphohistiocytosis: Experience from the Uppsala University Hospital

Background. Haemophagocytic lymphohistiocytosis (HLH) is a rare clinical syndrome characterized by fever, hepatosplenomegaly, cytopenia, and progressive multiple-organ failure. HLH in adults is often secondary to autoimmune diseases, cancer, or infections in contrast to familial HLH. Treatment of secondary HLH is directed against the triggering disease in addition to immunosuppressive therapy, the latter commonly according to the HLH-2004 protocol.Methods. We conducted a retrospective study to identify triggering diseases, disease-specific and immunosuppressive therapy administered, and prognosis in adult patients with secondary HLH. Patient data were collected from October 2010 to January 2015.Results. Ten adult patients with secondary HLH were identified. Seven were men, and the median age at diagnosis was 62 years. Five cases were triggered by malignant disease and five by infection. The median patient fulfilled five of the eight HLH-2004 diagnostic criteria. All patients fulfilled the criteria fever, cytopenia, and ferritin >500 µg/L. Median time from hospital admission to HLH diagnosis was 20 days. Four patients received immunosuppressive therapy according to the HLH-2004 protocol. The prognosis was dismal, especially for the patients with malignancy-associated HLH, of whom all died.Conclusion. HLH should be suspected in patients who present with fever, cytopenia, and ferritin >500 µg/L. Secondary HLH has a dismal prognosis. None of the patients with HLH triggered by malignancy survived. Achieving remission of the triggering disease seems to be important for a favourable outcome as, in all surviving patients, the haemophagocytic syndrome resolved after remission of the underlying infection.     

急性心肌梗死患者D二聚体质量浓度与远期预后的关系

目的 探讨急性心肌梗死(acute myocardial infarction,AMI)患者D二聚体(D-dimer)质量浓度与病情严重程度和远期心源性死亡的关系。方法 选取2013年1月至2020年1月收入首都医科大学附属北京友谊医院的AMI患者3 990例,根据D-dimer质量浓度分为3组:≤0.50 mg/L、0.51～0.80 mg/L、≥0.81 mg/L,平均随访时间为2.1 (1.0～4.0) 年。应用Cox比例风险回归模型评估D-dimer对心源性死亡的影响。结果 D-dimer≥0.81 mg/L组患者年龄较大、女性居多、体质量指数较低,既往合并高血压、糖尿病者较多,3支病变较为多见,住院期间肾小球滤过率较低,N末端B型利钠肽原峰值明显升高,左室射血分数<50%患者比例明显升高。D-dimer≥0.81 mg/L组患者在随访期间累计心源性病死率(18.7%)高于D-dimer≤0.50 mg/L组(2.3%)和D-dimer 0.51～0.80 mg/L组(6.1%),且校正其他危险因素后,D-dimer能独立预测AMI患者的心源性死亡(HR=1.71,95%CI:1.34~2.18,P<0.001)。结论 D-dimer能反映AMI患者病情的严重程度,且D-dimer升高可在一定程度上预测AMI患者远期心源性死亡事件发生率升高。
