Rural Midwestern Primary Care Nurse Practitioners’ Transition to Practice

Transition to practice experiences for new primary care nurse practitioners (NPs) is of interest, particularly considering the lack of requirements and options for formal training programs. The purpose of this article is to describe new primary care NPs’ experience and perceived needs of transitioning to practice. New Nebraska NPs were surveyed. The main findings include increased confidence and perceived preparedness after 3 months of practice, as well as challenges and helpful supportive services for transitioning to practice. Additional information on the transition to practice experience was provided and supports developing a formal program.     

Robust antibody response after a third BNT162b2 vaccine compared to the second among immunocompromised and healthy individuals,a prospective longitudinal cohort study

PurposeAs protection from COVID-19 following two doses of the BNT162b2 vaccine showed a time dependent waning, a third (booster) dose was administrated. This study aims to compare the antibody response following the third dose versus the second and to evaluate post-booster seroconversion.MethodsA prospective observational study conducted in Maccabi Healthcare Services. Serial SARS-CoV-2 Spike IgG tests, 1,2,3 and 6 months following the second vaccine dose and one month following the third were obtained. Neutralizing antibody levels were measured in a subset of participants. Per individual SARS-CoV-2 Spike IgG titer ratios were calculated one month after the booster administration compared to titers one month following the second dose and prior to booster.ResultsAmong 110 participants, 56 (51%) were women. Mean age was 61.7 ± 1.9 years and 66 (60%) were immunocompromised. One month after third dose, IgG titers were induced 7.83 (95 %CI 5.25–11.67) folds and 2.40 (95 %CI 1.90–3.03) folds compared to one month after the second, in the immunocompromised and immunocompetent groups, respectively. Of the 17 immunocompromised participants who were seronegative after the second dose, 4 (24%) became seropositive following the third. Comparing the titers prior to the third dose, an increase of 50.7 (95 %CI 32.5–79.1) fold in the immunocompromised group and 25.7 (95 %CI 19.1–34.7) fold in and immunocompetent group, was observed.ConclusionA third BNT162b2 vaccine elicited robust humoral response, superior to the response observed following the second, among immunocompetent and immunocompromised individuals.     

p53基因突变与骨髓增殖性肿瘤临床特征及预后关系

探究p53 基因突变与骨髓增殖性肿瘤（MPN）临床特征及预后的关系。方法 选取2017年1月～2020年1月本院收治的MPN患者126例，二代测序法检测患者p53 基因突变情况。对患者进行随访，统计患者总生存（OS）时间和累计生存率；分析p53 基因突变对患者临床特征、预后的影响。结果 126例MPN患者中12例（9.52%）检出p53基因突变，突变主要位于4~8号外显子上，不同类型患者的p53 基因突变检出率比较差异无统计学意义（P＞0.05）。p53突变组患者年龄大于p53 非突变组，WBC水平低于p53 非突变组（P＜0.05），两组患者的染色体核型、IPSS预后分层比较差异无统计学意义（P＞0.05）；p53 非突变组患者的OS时间、累计生存率均明显高于p53突变组患者（P＜0.05）。结论 MPN患者p53 基因突变发生率较高，与患者年龄、WBC水平、异常核型及IPSS预后分层相关，p53 基因突变会影响患者的预后，可作为临床筛查预后不良高风险人群的客观指标。     

A Mock Telephone Triage Experience for Nurse Practitioner Students

The ability to manage patient telephone calls competently and confidently is an important skill for nurse practitioners (NPs). A curriculum intervention was implemented in a pediatric NP program to promote this skill. Thirty-nine NP students participated in a mock telephone triage experience to determine whether triage, involving student/faculty mock parent telephone calls, would increase the student’s confidence and competence. A Likert scale pre/post questionnaire surveying perceived confidence, competence, and readiness to practice revealed an increase in students’ confidence in decision making, assessing the patient, and making a diagnosis over the phone.     

Managing the Breast Cancer Survivor in Primary Care

Early detection and improved treatments for breast cancer are increasing survival rates, thereby growing the number of survivors to almost 4 million in the United States. Continuing care after treatment is frequently provided in primary care. Evidence-based care includes a history review, physical examination, and imaging for recurrence and new cancers, along with health maintenance and health promotion. Additionally, survivors often experience long-term side effects from their disease and/or treatment, affecting health and quality of life. This article provides a synopsis of breast cancer treatment-related side effects and current evidence-based guidelines to assist the primary care provider caring for survivors.     

TRIM59 通过结合 BCLAF1 调控人皮肤黑色素瘤 SK-MEL-2 细胞的恶 性生物学行为

目的：探究三结构域蛋白59（TRIM59）调控人皮肤黑色素瘤细胞SK-MEL-2增殖、细胞周期、凋亡及迁移侵袭的作用机制，及其与Bcl2相关转录因子1（BCLAF1)之间的关系。方法：qPCR和WB法检测人表皮黑色素细胞HEMn-LP、人皮肤黑色素瘤细胞SK-MEL-2、UACC903、A375及36例邢台市人民医院2019年2月至2021年7月收集的皮肤黑色素瘤组织中TRIM59的mRNA和蛋白表达，使用脂质体将si-con、si-TRIM59转染至SK-MEL-2细胞中，WB法检测干扰TRIM59表达对细胞中周期蛋白D1（CCND1）、细胞周期素依赖性激酶2（CDK2）、肿瘤抑制蛋白基因（TP53）和 BCLAF1 蛋白表达的影响，CCK-8法、流式细胞术、划痕愈合实验、Transwell实验检测对细胞的活性、凋亡、迁移和侵袭的影响，免疫共沉淀（Co-IP）实验检测对细胞中TRIM59蛋白与BCLAF1结合能力的影响。结果：与HEMn-LP细胞相比，SK-MEL-2、UACC903、A375细胞中TRIM59 mRNA和TRIM59、BCLAF1蛋白均呈高表达（均P<0.05），SK-MEL-2细胞中TRIM59表达水平最高。相较于si-con组和Normal组，沉默TRIM59后，SK-MEL-2细胞的活性显著降低，细胞周期阻滞于G2期，CCND1、CDK2的蛋白表达显著降低，TP53蛋白和细胞凋亡率均显著升高，划痕抑制率明显升高，迁移侵袭细胞数明显降低（均P<0.05）。免疫共沉淀实验结果显示，TRIM59与BCLAF1之间存在蛋白结合关系。TRIM59与 BCLAF1 在肿瘤组织中的表达呈显著的正相关（r=0.878，P<0.001）。结论：干扰TRIM59表达能够抑制人皮肤黑色素瘤SK-MEL-2细胞的增殖、迁移和侵袭而促进凋亡，抑制SK-MEL-2细胞的恶性生物学行为，其机制可能与TRIM59结合BCLAF1有关。
