甲状腺乳头状癌伴发桥本甲状腺炎的临床研究

背景与目的：甲状腺乳头状癌（papillary thyroid carcinoma，PTC）和桥本甲状腺炎（Hashimoto’s thyroiditis，HT）的发病率均呈上升趋势，两者之间的关系已成为目前研究的热点。探讨PTC和HT之间的关系。方法：回顾性分析2014—2015年期间在中国科学院大学附属肿瘤医院头颈肿瘤外科行甲状腺癌手术治疗的首诊患者306例，术后病理学检查均明确诊断为PTC，其中术后病理学确诊伴发HT者42例，比较伴发HT与未伴发HT患者的临床病理学特征。结果：PTC患者女性发病年龄高于男性（46.2岁 vs 41.9岁）。相较于与未伴发HT的PTC患者，伴发HT的患者中女性比例更高（93% vs77%），中央区淋巴结数目较多［（5.0±3.4）枚 vs （2.5±2.7）枚］，术前促甲状腺激素（thyroid-stimulating hormone，TSH）水平较高［（3.28±1.91）μU/mL vs （2.12±1.29）μU/mL］，术前抗甲状腺过氧化物酶抗体（thyroid peroxidaseantibody，TPOAb）阳性率较高（55% vs 14%），术前甲状腺球蛋白抗体（thyroglobulin antibodies，TgAb）阳性率较高（69% vs 13%）。发生中央区淋巴结转移的患者中，中央区淋巴结转移数目与中央区淋巴结总数显著相关（Pearson相关系数=0.582）。多因素logistic回归分析发现，男性、低龄、被膜侵犯是PTC患者中央区淋巴结转移的独立危险因素。结论：伴发HT对PTC患者的预后无显著影响。伴发HT的PTC患者TSH水平显著偏高，提示HT可能是PTC发病风险因素之一。中央区淋巴结转移数目与中央区淋巴结总数相关，推测PTC淋巴结转移可能与淋巴结炎症反应相关。     

Erythrocyte sphingolipid species as biomarkers of Alzheimer's disease

Diagnosing Alzheimer's disease (AD) in the early stage is challenging. Informative biomarkers can be of great value for population-based screening. Metabolomics studies have been used to find potential biomarkers, but commonly used tissue sources can be difficult to obtain. The objective of this study was to determine the potential utility of erythrocyte metabolite profiles in screening for AD. Unlike some commonly-used sources such as cerebrospinal fluid and brain tissue, erythrocytes are plentiful and easily accessed. Moreover, erythrocytes are metabolically active, a feature that distinguishes this sample source from other bodily fluids like plasma and urine. In this preliminary pilot study, the erythrocyte metabolomes of 10 histopathologically confirmed AD patients and 10 patients without AD (control (CTRL)) were compared. Whole blood was collected post-mortem and erythrocytes were analyzed using ultra-performance liquid chromatography tandem mass spectrometry. Over 750 metabolites were identified in AD and CTRL erythrocytes. Seven were increased in AD while 24 were decreased (P<0.05). The majority of the metabolites increased in AD were associated with amino acid metabolism and all of the decreased metabolites were associated with lipid metabolism. Prominent among the potential biomarkers were 10 sphingolipid or sphingolipid-related species that were consistently decreased in AD patients. Sphingolipids have been previously implicated in AD and other neurological conditions. Furthermore, previous studies have shown that erythrocyte sphingolipid concentrations vary widely in normal, healthy adults. Together, these observations suggest that certain erythrocyte lipid phenotypes could be markers of risk for development of AD.     

The opportunity costs of caring for people with dementia in Southern Spain

Objective

The aim of this paper is to study the opportunity costs (OC) that are involved in being a caregiver and to compare them with the direct costs assumed by the State and the families. We evaluate direct cost (those that imply a payment-out-of-pocket) and indirect cost (those that imply a dedication in time). We hypothesized that costs increase with the severity of the dementia, with the educational level and active occupational situation of caregiver. They are greater if the caregiver is male, but if the patient and caregiver cohabit they are reduced.

Lucio phenomenon mimicking antiphospholipid syndrome: The occurrence of antiphospholipid antibodies in a leprosy patient

Lucio phenomenon is an atypical reaction of leprosy, characterized by vasculitic lesions that can mimic antiphospholipid syndrome (APS) clinically. Distinguishing the two can be difficult as antiphospholipid autoantibodies may be present in patients with leprosy. We report on a 32‐year‐old female patient presenting with a sudden onset of fever, hemorrhagic bullae, and skin necrosis on her lower legs. She was treated for APS due to the presence of antiphospholipid antibodies but had an inadequate response. A skin biopsy revealed thrombotic vasculopathy and necrotizing vasculitis associated with aggregation of foam cells in the perivascular area and subcutis, with acid‐fast bacilli in the histiocytes and blood vessel walls. Direct immunofluorescence showed IgM, C3, and fibrinogen deposition in the superficial and deep dermal blood vessels. The pathology confirmed the diagnosis of Lucio phenomenon, and appropriate therapy was given. It is essential to evaluate the patient comprehensively, including clinical, serological, and pathological aspects, to obtain the correct diagnosis.     

The management of emergency hospital visits for inflammatory bowel diseases: A French national expert consensus report

BackgroundManagement of inflammatory bowel diseases (IBD) in the emergency department is often suboptimal.AimsTo develop a national consensus checklist of indicators to facilitate decision-making in emergency departments concerning hospitalisation and referral for abdominopelvic computed tomography (CT).MethodsA Delphi survey was used to obtain consensus on a checklist of clinical and biological variables. 119 healthcare professionals experienced in treating IBD were invited to participate. Panellists were provided with a literature survey and invited to agree or disagree with items on a prototype checklist. Two successive rounds of voting were organised.ResultsThe prototype checklist included fifteen clinical or laboratory indicators for hospitalisation or CT. Four indicators were not retained in the Delphi process and four additional indicators added. The final indicators retained were: abdominal signs/symptoms of disease exacerbation, intravenous morphine titration, fever, vomiting, dehydration, recent intestinal surgery, ano-perineal abscess, bowel obstruction, haemodynamic instability, anaemia, acute kidney failure and elevated C-reactive protein. Consensus for the retained indicators was >88%.ConclusionsUse of this consensus checklist for the management of IBD in the emergency department may help improve standards of care and thus reduce the burden of these diseases.     

Intussusception in a premature neonate: A rare and often misdiagnosed clinical entity

Intussusception is a very rare cause of intestinal obstruction in neonates. It is of extremely rare occurrence among premature neonates. We present a case of 11-day-old premature neonate who presented with abdominal distension, intolerance to feeds, vomiting, significant bilious aspirate and bleeding per rectum. The initial diagnosis of necrotizing enterocolitis (NEC) led to a delay in the diagnosis. On exploratory laparotomy, it turned out to be a case of ileo-colic intussusception with Meckel''s diverticulum as a lead point. This site of intussusception (ileo-colic) and presence of a lead point among premature neonate is of exceedingly rare occurrence and very few such cases have been reported.In this article, the published work about clinical features and management on intussusceptions in premature neonates has been reviewed. The authors intend to highlight the difficulty in distinguishing the NEC and intussusception. Subtle clinical and radiological features which can help in differentiating the two conditions have been emphasized. This can avoid the delay in diagnosis and management which can prove critical. High index of suspicion with timely intervention is the key for optimizing outcome. A diagnosis of intussusception should always be considered in any preterm infant with suspected NEC.     

Children’s participative citizenship within the context of integral care and daily life

The concept of participation was reviewed as a component of children's citizenship in order to promote a programme for Integral Development. A narrative revision of the literature was carried out as well as a group discussion was organized along with the staff of an Integral Care Programme, in order to identify notions of democracy and child citizenship related to care and rearing. Some elements that favoured the child participation and some parenting skills were identified. Among the elements that must be encouraged in children are: the development of emotional, cognitive and communicative skills and promotion of decision-making; among the parent skills development included are: sensitivity and responsivity; establishing routines and participation experiences. It is important to stand out that the identified elements to promote child participation and parental competences should be adapted to every specific cultural context.     

Therapeutic effect of mesenchymal stem cell on Hashimoto’s thyroiditis in a rat model by modulating Th17/Treg cell balance

Abstract

The autoimmune condition Hashimoto’s thyroiditis (HT) is a disease wherein lymphocytes mediate the autoimmune damage and destruction of the thyroid gland. There are currently no effective means of treating HT, with the primary strategies of thyroid hormone therapy, surgery, or immunomodulatory therapy being associated with serious risks and side effects. There is thus a clear and urgent need to identify novel treatments for HT. In this study, we utilize female SD rats induced HT to evaluated the ability of transplanted MSCs to regulate Th17/Treg interactions in a rat Hashimoto’s thyroiditis (HT) model system. The results showed that Rats in the HT model group exhibited increased thyroid autoantibody levels consistent with successful model development, whereas these levels were lower in rats treated with MSCs. There were also fewer thyroid lesions and less lymphoid infiltration of the thyroid in MSC-treated rats relative to HT model rats, as well as fewer Th17 cells and more Treg cells – an observation consistent with the cytokine analyses. All of these showed that MSCs can regulate Th17/Treg interactions in a rat Hashimoto’s thyroiditis (HT) model system. It suggested that transplanted MSCs could be a potential immunotherapy strategy for the treatment of Hashimoto’s thyroiditis.     

The effect of Benson’s relaxation response on sleep quality and anorexia in cancer patients undergoing chemotherapy: A randomized controlled trial

Background and objectivesPatients with cancer experience many side effects due to its nature and usual treatments. Sleep disorders and anorexia are the most commonly reported symptoms in cancer patients undergoing chemotherapy. The present study aimed to investigate the effect of Benson's Relaxation Response (BRR) on sleep quality and anorexia in cancer patients undergoing chemotherapy.Methodology and participantsIn the present clinical trial, a total of 84 patients were enrolled and randomly divided into two groups of experimental and control. Benson's relaxation response was administered to the experimental group twice a day over 5 consecutive days. Data was collected using St. Mary's Hospital Sleep Questionnaire (SMHSQ) and anorexia questionnaire with Visual Analog Scale (VAS).ResultsThe results of our study showed a significant improvement in the sleep quality in the experimental group at 24 (p = 0.02) and 48 (p = 0.001) hours after the intervention compared to the control group. Benson's relaxation response (BRR) also had a significant effect on the anorexia in the experimental group at 24 (7.5 ± 1.6) and 48 (6.9 ± 2.1) hours after the intervention compared to the control group. No side effects were reported during the study and follow-up period.ConclusionBenson's relaxation response as a complementary method may improve sleep quality and anorexia in cancer patients undergoing chemotherapy. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.
