Pharmacy patron perspectives of community pharmacist administered influenza vaccinations

Background

One approach to boost influenza vaccination coverage has been to expand immunization authority. In 2012, the province of Ontario gave community pharmacists the authority to administer the influenza vaccine.

The infantile cutaneous microbiome: A review

Recent focus on the neonatal intestinal microbiome has advanced our knowledge of the complex interplay between the intestinal barrier, the developing immune system, and commensal and pathogenic organisms. Despite the parallel role of the infant skin in serving as both a barrier and an interface for priming the immune system, large gaps exist in our understanding of the infantile cutaneous microbiome. The skin microbiome changes and matures throughout infancy, becoming more diverse and developing the site specificity known to exist in adults. Delivery method initially determines the composition of the cutaneous microbiome, though this impact appears transient. Cutaneous microbes play a critical role in immune system development, particularly during the neonatal period, and microbes and immune cells have closely intertwined, reciprocal effects. The unique structure of newborn skin influences cutaneous microbial colonization and the development of dermatologic pathology. The development of the infantile skin barrier and cutaneous microbiome contributes to future skin pathology. Atopic dermatitis flares and seborrheic dermatitis have been linked to dysbiosis, while erythema toxicum neonatorum is an immune response to the establishment of normal bacterial skin flora. Physicians who care for infants should be aware of the impact of the infantile skin microbiome and its role in the development of pathology. A better understanding of the origin and evolution of the skin microbiome will lead to more effective prevention and treatment of pediatric skin disease.     

PI3K抑制剂ZSTK-474对结直肠癌细胞增殖和侵袭的影响

目的:探讨PI3K抑制剂ZSTK-474对结直肠癌细胞增殖和侵袭的影响。方法:采用不同浓度（0、1、2、4、6、8和10 μmol/L）ZSTK-474处理结直肠癌HT-29和HCT-116细胞24 h和48 h，CCK8法检测细胞增殖活性并计算出ZSTK-474在两株结直肠癌细胞中的半数抑制浓度（IC50）。根据IC50的值选用浓度为4 μmol/L的ZSTK-474作用HT-29和HCT-116细胞24 h，同时设置加入等量的0.1%DMSO为对照。采用平板克隆形成实验检测细胞增殖，流式细胞仪检测细胞凋亡，qRT-PCR检测细胞PI3K、Akt的mRNA水平，Western blot 检测细胞PI3K、Akt的蛋白水平。结果:ZSTK-474可明显抑制HT-29和HCT-116细胞的增殖，且呈时间和剂量依赖性。ZSTK-474可抑制HT-29和HCT-116细胞的侵袭能力，但不影响其凋亡。ZSTK-474处理HT-29和HCT-116细胞24 h后，PI3K和Akt的mRNA和蛋白表达水平均显著下降。结论:ZSTK-474能够抑制结直肠癌细胞增殖，并且能抑制其侵袭。     

Same-Day Yttrium-90 Radioembolization: Feasibility with Resin Microspheres

Purpose

To evaluate the feasibility of a same-day yttrium-90 (⁹⁰Y) radioembolization protocol with resin microspheres (including pretreatment angiography, lung shunt fraction [LSF] determination, and radioembolization) for the treatment of hepatocellular carcinoma (HCC) and liver metastases.

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.
