农村老年人老化期望现状及影响因素研究

目的 了解农村老年人的老化期望现状，分析其影响因素，为针对干预提供参考。 方法 采用一般资料调查表、UCLA孤独感量表简化版、老化期望量表、简版自我感知老化量表对199名农村老年人进行问卷调查。 结果 老化期望总分为32.72±9.18，孤独感得分为15.11±3.82，自我感知老化得分为52.75±2.76；多元线性回归分析显示，性别、婚姻状况、患慢性病种数、独居、孤独感、自我感知老化及经济来源是农村老年人老化期望的影响因素（调整R2=0.612，均P＜0.05）。 结论 农村老年人的老化期望水平较低，女性、孤独、无配偶、患慢性病较多、老化态度消极及低收入人群是关注的重点。     

慢阻肺急性加重期患者延迟就医与家庭动力学的相关性研究

目的研究慢阻肺急性加重期患者延迟就医与家庭动力学的相关性,希望能够为慢阻肺急性加重期患者拟定护理措施提供科学依据。方法选取2017年1月-2019年12月我院240例诊断为慢阻肺急性加重期的患者为研究对象。根据患者入院就医的时间进行分组,时间≥24h的延迟就医的患者为观察组,时间<24h的及时就医患者为对照组。结果两组患者在文化水平、家庭年收入、在职状态、医疗保险和婚姻状况和APACHEⅡ评分比较(P<0.05)。观察组患者疾病观念、个性化、系统逻辑和家庭氛围得分比对照组高(P<0.05)。Pearman的相关性分析结果显示:慢阻肺急性加重期患者延迟就医时间与各个层面分数以及家庭动力总分呈现负相关性(P<0.05)。应变量为延迟就医为应变量,患者的一般资料为自变量,经Logistic回归分析结果表明:延迟就医的影响因素为文化水平、家庭动力评分、职业状态、家庭收入、婚姻状况和APACHEⅡ评分。结论慢阻肺急性加重期患者家庭动力总分与疾病观念、个性化、系统逻辑和家庭氛围得分与延迟就医时间呈现负相关性,患者延迟就医的影响因素是家庭动力学评分。     

Human factors in pelvic surgery

In the pelvis, anatomic complexity and difficulty in visualization and access make surgery a formidable task. Surgeons are prone to work-related musculoskeletal injuries from the frequently poor design and flow of their work environment. This is exacerbated by the strain of surgery in the pelvis. These injuries can result in alterations to a surgeons practice, inadvertent patient injury, and even early retirement. Human factors examines the relationships between the surgeon, their instruments and their environment. By bridging physiology, psychology, and ergonomics, human factors allows a better understanding of some of the challenges posed by pelvic surgery. The operative approach involved (open, laparoscopic, robotic, or perineal) plays an important role in the relevant human factors. Improved understanding of ergonomics can mitigate these risks to surgeons. Other human factors approaches such as standardization, use of checklists, and employing resiliency efforts can all improve patient safety in the operating theatre.     

结直肠腺瘤危险因素

目的 研究结直肠腺瘤发生相关的危险因素,为结直肠早癌病变的筛查及诊疗提供预警信息。方法 选取2014年1月至2020年6月于河北医科大学第二医院行结肠镜检查经病理诊断为结直肠腺瘤的患者1 126例作为病例组,以同期行结肠镜检查结果阴性的患者1 800例作为对照组。收集患者性别、年龄、吸烟史、饮酒史、排便习惯(正常、腹泻、便秘、腹泻与便秘交替)、总胆固醇及甘油三酯水平等资料。进行多因素Logistic回归分析,探究上述因素对结直肠腺瘤发生的影响。为了进一步排除混杂因素的干扰,组间1∶1匹配,进行多因素条件Logistic回归分析,探究结直肠腺瘤发生的独立危险因素。结果 多因素Logistic回归分析显示,性别、年龄、饮酒史、吸烟史、排便习惯、总胆固醇和甘油三酯水平为结直肠腺瘤发生的独立危险因素(P<0.05)。多因素条件Logistic回归分析显示,排便习惯及甘油三酯水平是结直肠腺癌发生的独立危险因素,慢性腹泻、慢性便秘患者发生结直肠腺瘤的风险高于排便习惯正常者(P<0.05),甘油三酯水平较高患者发生结直肠腺瘤的风险高于甘油三酯水平正常者(P<0.05)。结论 排便习惯及甘油三酯水平是结直肠腺瘤发生的独立危险因素,慢性腹泻、慢性便秘、甘油三酯升高者发生结直肠腺瘤风险更高。     

A retrospective analysis comparing set up errors from standard versus customised headrests for head and neck radiotherapy

IntroductionIn response to advice from The National Institute for Health and Care Excellence ⁽¹⁾ to reduce hospital visits during COVID-19, standard headrests were introduced for head and neck radiotherapy within Northern Centre for Cancer Care (NCCC). The standard headrest requires one mould room appointment compared to 3 appointments with customised headrests.MethodsTwo groups of 10 patients treated between December 2019 and June 2020 were retrospectively analysed by 1 observer. Groups were stratified according to age, sex and tumour site. One group had customised headrest and the other had standard headrest. Five hundred and forty seven cone beam computed tomography images were reviewed. A 6 Degree of Freedom match was performed then chin, shoulder and spine position were assessed using dosimetrist drawn structures. Structures out of the tolerance were recorded. A chi-squared test was used for statistical analysis.ResultsThe out of tolerance chin position count recorded was 21 for customised headrest and 36 for standard headrest, p-value 0.046. The shoulder position count was 13 for customised headrest and 77 for standard headrest p-value <0.001. The spine position count was 3 for CHR and 21 for standard headrest, p-value <0.001. This means the headrests compared are not equivalent in terms of set up reproducibility. Overall the standard headrest group had 10 set-up re-scans and no set up re-scans were recorded in the customised headrest group.ConclusionFewer hospital visits with SHR reduce patient exposure to COVID-19. However, CHR provided a more reliable level of immobilisation in this study.Implications for practiceThe radiotherapy service will be reviewed in line with these findings.     

Neuroblastoma: a master of disguise and a challenge to cure

Neuroblastoma is one of the commonest childhood cancers and typically affects very young children. It is characterized by a very broad spectrum of clinical presentation and outcome, driven by the biology of the tumour. This ranges from ‘low risk’ tumours, most commonly found in infants, which may spontaneously regress and have an excellent prognosis with minimal or no treatment, to ‘high risk’ disease, which carries a poor prognosis despite intensive multi-modal treatment. Although particular presentations may be associated with favourable or unfavourable outcome, the clinical features may mask the underlying biology of the tumour and a full assessment of the clinical and biological features is required to determine appropriate treatment. The International Neuroblastoma Risk Group classification, based on the age of the patient and the stage, grade and genetics of the tumour, is used to stratify treatment according to risk factors. This review provides an overview of current neuroblastoma management, focusing on how classification is applied in practice, and how this is used to determine individual patient treatment. The challenges that remain in treating patients with high-risk disease are discussed.
