The Association Between Acculturation and Health Insurance Coverage for Immigrant Children from Socioeconomically Disadvantaged Regions of Origin

Among immigrant children whose parents have historically had lower education, the study explored which immigrant children were most likely to have coverage based on maternal region of origin. The direct and indirect relationship of acculturation on immigrant children’s coverage was also assessed. A subsample of US-born children with foreign-born mothers from the Early Childhood Longitudinal Survey-Kindergarten Cohort was analyzed using multinomial logistic regressions (n = 1,686). Children whose mothers emigrated from the Caribbean or Indochina had greater odds of being insured compared to children whose mothers emigrated from Mexico. Moreover, Latin American children did not statistically differ from Mexican children in being uninsured. Maternal citizenship was positively associated with children’s coverage; while living in a household with a mother who migrated as a child was negatively associated with private insurance. To increase immigrant children’s coverage, Latin American and Mexican families may benefit from additional financial assistance, rather than cultural assistance.     

脾动脉瘤的临床特征与腔内治疗：附30例报告

背景与目的:脾动脉瘤(SAA)是一类少见、具有潜在致命破裂风险的内脏动脉瘤疾病。SAA的传统手术方式为开腹切除动脉瘤及脾脏。近年来,随着介入技术和材料的发展,SAA的腔内治疗越来越普及。相比于开放手术,腔内治疗具有微创、简便、术后快速康复的优势。本文探讨SAA腔内治疗的有效性和安全性。方法:回顾性分析2012年1月—2019年12月在中南大学湘雅医院血管外科治疗的30例SAA患者资料,并介绍了我科治疗SAA的3种介入手术方式。结果:患者30例均行腹部CTA明确SAA诊断,其中近脾门型17例,中间型9例,远脾门型4例;囊状动脉瘤19例,梭形动脉瘤11例。30例均采取腔内治疗方法,其中21例行SAA栓塞术,6例行脾动脉支架置入术,3例行脾动脉裸支架置入+栓塞术。患者术后平均住院时间4 d,平均住院费用5万元,术后发生腹痛、呕吐、发热等症状10例,症状均在3 d以内缓解,无后遗症发生。发生穿刺点出血1例,保守治疗好转后出院。住院期间无急性脾梗死发生,没有发生需再次手术的并发症。22例患者术后随访3～6个月,CT复查示动脉瘤完全血栓化,未见造影剂进入;出现无症状局灶性脾梗死5例。结论:介入腔内手术可在保留脾脏的情况下治疗SAA,治疗效果确切,且创伤小,术后恢复快,并发症发生概率低,住院时间短,费用相比开放手术无明显增加。腔内治疗可作为绝大部分SAA的首选治疗,具体手术方式需根据术前CTA显示的SAA形态及位置来决定。

Percutaneous coronary intervention of or through saphenous vein grafts or internal mammary arteries: the impact of stents, adjunctive pharmacology, and multicomponent distal protection.

We hypothesized that the use of stents and aggressive adjunctive pharmacotherapies has been associated with lower rates of complicating myocardial infarction (MI) and improved long-term outcomes compared to either previous balloon-only percutaneous coronary intervention (PCI) or atheroablative intervention for lesions of or through saphenous vein grafts (SVGs) and/or internal mammary arteries (IMAs). PCI of SVG has been complicated by relatively high rates of procedural MI and less favorable long-term outcomes than native vessel PCI, stimulating the development and application of an array of technologies. This study was based on retrospective review of stent-era (1999-2004) 5-year experience of a single center with 95 SVG procedures in 85 patients and 20 IMA procedures in 20 patients. These cases were compared with the previously published experience of one of the operators during the balloon-only period and literature review of the application of multiple technologies to SVG intervention, as well as consideration of the reoperation alternative. There was one in-hospital death each in the SVG cohort (1%) and in the IMA cohort (5%). There were SIX procedural MIs (6%), defined by total CK > normal, and 19 procedural MIs (20%) based on troponin-I > 1.0. Follow-up has been from 4 months to 5 years (average, 2.5 years), with 91% survival and one late CABG in the IMA group. SVG PCI with stents and adjunctive pharmacotherapies is associated with relatively low rates of procedural MI and favorable long-term outcomes.     

Sea-blue histiocyte syndrome in bone marrow secondary to total parenteral nutrition including fat-emulsion sources: a clinicopathologic study of seven cases

Bone marrow examination revealed a lipid-laden histiocytosis in seven patients undergoing long-term total parenteral nutrition necessitated by extensive short-bowel surgical resection. Clinical abnormalities occurred during this treatment which required bone marrow examination. These included hepatosplenomegaly and peripheral blood cytopenia; the median time to the detection of these abnormalities was 64 months.   The most striking change within the bone marrow was the presence of many pigment-laden histiocytes which had the typical morphology of sea-blue histiocytes seen in the so-called idiopathic sea-blue histiocyte syndrome. The occurrence of sea-blue histiocytosis in the bone marrow in association with long-term parenteral nutrition for short-bowel syndrome has not, to our knowledge, been reported previously and should now be considered in the differential diagnosis of bone marrow sea-blue histiocytosis.
