A review of incisional hernia repairs: preoperative weight loss and selective use of the mesh repair

At the Shouldice Clinic pre-operative weight loss is used prior to incisional hernia repairs. Mesh repair is selectively used, based on specific hernia characteristics. A series of 236 patients were reviewed and followed up for 36 months. Data were available on 188 patients (80%). There were 15 recurrences (8%). The number of obese patients was reduced from 67 (35.6%) to 25 (13.3%) through the weight loss program. The hernia diameter, gastrointestinal complications, and surgical site infection were significantly related to recurrence but not the type of repair, obesity, location, or previous recurrences. The risk factors of incisional hernias include size, intestinal complications and infections. A selective use has a comparable result to the exclusive use of mesh repair. Weight reduction has yet to be shown to affect the rate of recurrence, and further prospective studies are required.

Meaning and normativity in nurse–patient interaction

Abstract It is a fundamental assumption in nursing theory that it is important for nurses to understand how patients think about themselves and the contexts they are in. According to modern theories of hermeneutics, a nurse and a patient must share the same concepts in order to communicate beliefs with the same content. But nurses and patients seldom understand medical concepts in exactly the same way, so how can this communicative aim be achieved in interaction involving medical concepts? The article uses a theory of concepts from recent cognitive science and philosophy of mind to argue that nurses and patients can share medical concepts despite the diversity of understanding. According to this theory, two persons who understand medical language in different ways will nevertheless possess the same medical concepts if they agree about the normative standards for the applications of the concepts. This entails that nurses and patients normally share medical concepts even though patients’ conceptions of disease and illness are formed in idiosyncratic ways by their social and cultural contexts. Several practical implications of this argument are discussed and linked to case studies. One especially important point is that nurses should seek to make patients feel comfortable with deferring to a medical understanding. In many cases, an adequate understanding of patients presupposes that nurses manage to do this. Another implication is that deference‐willingness to normative meaning is not equivalent to the actual application of concepts. Deference‐willingness should rather be thought of as a pre‐communicative attitude that it is possible for patients who are not fully able to communicate to possess. What is important is that nurses and patients have the intention of conforming to the same meaning.     

急性重症肝炎患者发生肝性脑病危险因素多元Logistic回归研究

目的探索急性重症肝炎患者发生肝性脑病的危险因素，以便进行早期干预。方法收集血浆凝血酶原时间（PT）延长，活动度〈40％的急性重症肝炎患者69例，对69例患者的年龄、性别和基础疾病等临床背景资料和总胆红素、直接胆红素、谷草转氨酶（AST）、谷丙转氨酶（ALT）、血浆白蛋白、胆碱脂酶、血浆凝血酶原时间（PT）、白细胞计数（WBC）、血小板计数（Plt）等实验室检查数据进行单因素分析和多元Logistic回归分析。结果单因素分析和多元Logistic回归分析均提示年龄、血胆红素水平和血浆凝血酶原时间在肝性脑病组和非肝性脑病组之间有统计学差异。结论约30％的急性重症肝炎患者发展成为肝性脑病。高龄、血浆凝血酶原时间延长、活动度下降、高血浆总胆红素等是急性重症肝炎患者发展成为肝性脑病的潜在危险因素。     

Using stories to battle unintentional injuries: Narratives in safety and health communication

After 14 years of rising death rates due to unintentional injuries in the U.S., it is time to ask how safety messages can be redesigned to have a greater impact on risky behavior. To this end, many researchers have called for a new, narrative approach to prevention messages—based on persuasive stories about people who have suffered injuries and illnesses in the past. Still, there is scant evidence that story-based communications are more effective than equivalent non-narrative messages at changing actual (rather than self-reported) safety and health behavior. Our research examined the impact of injury stories on actual safety behavior in a controlled experimental setting at a US university. Teams of participants assembled a product (a child's swing) using written instructions. The instructions contained safety messages targeting assembly mistakes that have been linked to serious injuries in children who play on swings. Participant teams were randomly assigned to three conditions: assembly instructions containing story-based safety messages, instructions with concrete (but non-anecdotal) safety messages, and instructions with traditional abstract safety messages. After adjustment for covariates, story-based messages resulted in a 19 percent improvement in safety behavior, compared with non-narrative communications. Importantly, injury stories did not create undue fear of the message object, demonstrating that brief anecdotes about accident victims can convince people to take reasonable precautions without creating unwarranted alarm about risks.     

1142例胃癌切除术围手术期死亡因素分析

目的研究影响胃癌围手术期死亡的主要因素,为指导选择合理的切除范围和手术方式提供依据。方法回顾1989年1月至2004年3月胃癌手术后1142例患者的临床资料,按照不同年代分为3组,第1组:1989年1月至1994年1月,405例;第2组:1994年2月至1999年1月,377例;第3组:1999年2月至2004年3月,360例。比较3组间的围手术期死亡率,采用Logistic多因素回归分析研究影响手术死亡率的危险因素。结果全组患者术后并发症发生率和死亡率分别为11.2%(128/1142)和3.6%(41/1142)。第1、2、3组的术后并发症发生率依次为13.1%、10.1%和10.3%;3组比较,P>0.05。3组手术死亡率依次为4.7%、3.4%和2.5%,3组比较,P>0.05。术后最常见的并发症是吻合口瘘(24.2%,31/128),影响手术死亡的主要因素为临床Ⅳ期、姑息性切除术、联合脏器切除及术前合并症的存在(P<0.05)。Logistic多元回归分析显示淋巴结的清除范围和手术方式不是影响手术死亡的主要因素(P>0.05)。结论胃癌晚期患者手术死亡率高,对胃癌Ⅳ期患者行姑息性切除手术时应避免施行不必要的淋巴结清除及联合脏器切除术。

Development of a new Adolescent Patient-Provider Interaction Scale (APPIS) for youth at risk for STDs/HIV

PurposeAlthough an adult model of patient-provider mutual exchange of information has been proposed, there is no guiding model for adolescents or measurement methodology. Our purpose was to develop a new scale of patient-provider interaction for adolescents accessing reproductive health care and at risk for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV), and assess the reliability and validity of the scale.MethodsThe Adolescent Patient-Provider Interaction Scale (APPIS) was developed from the Roter and Hall theory of doctor-patient relationships, previously validated adolescent satisfaction and communication scales, and focus group and individual elicitation interviews. To assess construct validity, the new nine-item APPIS was compared with the satisfaction scale used by the Young Adult Health Care Survey (YAHCS), and Kahn’s Provider Communication Scale. Pearson correlation coefficients were used to examine convergence across scales, and factor analysis of the APPIS was performed.ResultsThe study recruited 192 African American girls aged 17.9 ± 1.7 years (range 15–21 years) from three sites: a county STD clinic (n = 51), urban adolescent clinic (n = 99), and a family planning clinic (n = 42). Most participants (85%) rated their overall health care highly (≥ 7 on a 10-point scale); 49% felt that both the provider and patient were “in charge” of the visit, and 88% “strongly agreed” or “agreed” that there was an equal “exchange of information” during the visit. The APPIS showed good internal consistency (Cronbach alpha = .75), and moderate convergence with the six-item YAHCS scale (r = .57, p < .001) and seven-item Kahn scale (r = .48, p < .001). Three factors emerged from exploratory factor analyses, supporting our conceptualization of patient-provider interaction as being multi-dimensional.ConclusionsA new theory-based scale of adolescent patient-provider interaction compares favorably with previous scales of health care satisfaction and communication. The new APPIS may be useful for evaluating approaches to improve health care outcomes for adolescents at-risk for STDs and HIV.
