Prospective characterization of incident hepatic steatosis in pediatric and adolescent patients after total pancreatectomy with islet autotransplantation

BackgroundHepatic steatosis has been described as a common finding in adults following total pancreatectomy with islet autotransplantation (TPIAT) but it is unknown if this occurs in children and adolescents.ObjectivesTo define the frequency of post-TPIAT hepatic steatosis in a sample of children and adolescents and to identify clinical predictors of incident steatosis post-TPIAT.MethodsIn this prospective study, consecutive participants at least 1-month post-TPIAT underwent a liver MRI with proton density fat fraction (PDFF) and blood draw at our pediatric academic medical center between April 2021 and January 2022. Comparison clinical pre-TPIAT liver MRI or ultrasound and insulin use and graft function data were extracted from the medical record. T-tests were used for the comparison of means across continuous variables between participants with and without post-TPIAT steatosis.ResultsA total of 20 participants (mean: 13 ± 4 years; 12 female) were evaluated. Mean liver PDFF at research MRI was 7.4 ± 6.2% (range: 2–25%). Seven participants (35%) had categorical hepatic steatosis (PDFF>5%) post-TPIAT, five of whom had pre-TPIAT steatosis, reflecting a 13% (2/15; 95% CI: 2–40%) incidence of post-TPIAT steatosis. Participant characteristics were not significantly different between subgroups with and without post-TPIAT steatosis. Mean PDFF at research MRI was not different between graft function subgroups (7.5% optimal/good vs. 7.3% marginal/failure; p = .96).ConclusionOur study shows a moderate prevalence but low incidence of hepatic steatosis in a small sample of children and adolescents post-TPIAT. This study raises questions about a causal relationship between TPIAT and hepatic steatosis.     

肾周脂肪梅奥粘连概率评分系统在肾癌后腹腔镜肾部分切除术中的应用

目的探讨肾周脂肪梅奥粘连概率评分系统（MAP）在肾癌后腹腔镜肾部分切除术中的临床应用价值。 方法回顾性分析2015年1月至2020年6月徐州医科大学附属淮安医院泌尿外科收治的行后腹腔镜肾部分切除术的153例肾癌患者的临床病例资料。依据MAP评分系统将其分为低度复杂组、中度复杂组和高度复杂组三组。比较各组间的手术时间、术中出血量、术中及术后并发症、术中热缺血时间、术后住院时间及术后血肌酐变化情况。 结果在153例患者中，低度复杂组68例，中度复杂组58例和高度复杂组27例。三组患者在年龄、性别、术前血肌酐水平、肿瘤最大径、肿瘤位置、BMI、RENAL评分等方面差异无统计学意义（P>0.05）。随着复杂程度的提高，手术时间、术中出血量也在不断增加（P<0.05）；而术中热缺血时间、术后住院时间及术后血肌酐水平无明显变化（P>0.05）。在术中并发症方面，随着复杂程度的提高，术中并发症的发生率也在增加（P<0.05），且高度复杂组的术后并发症发生风险是低度复杂组的13.895倍（P=0.002)，MAP评分系统预测术中并发症发生的精度较高（AUC=0.757，P=0.002）。但是术后并发症各组比较差异无统计学意义（P>0.05）。 结论MAP评分系统在肾癌后腹腔镜肾部分切除术中，对预估手术难度及术中并发症发生风险有较好的临床应用价值。     

Fat shaming under neoliberalism and COVID-19: Examining the UK’s Tackling Obesity campaign

This article explores the dynamics between fat shaming, neoliberalism, ideological constructions of health and the ‘obesity epidemic’ within the UK, using the UK Government’s recent Tackling Obesity campaign in response to Covid-19 as an illustration. We draw attention to how fat shaming as a practice that encourages open disdain for those living with excess weight operates as a moralising tool to regulate and manage those who are viewed as ‘bad’ citizens. In doing so, we begin by outlining how the ideological underpinnings of ‘health’ have been transformed under neoliberalism. We then consider the problematic use of fat shaming discourses that are often used as tools to promote ‘healthy’ lifestyle choices by those who view it as not only an acceptable way of communicating the health risks associated with obesity but also a productive way of motivating people with obesity to lose weight. Drawing on Graham Scambler’s theoretical framework regarding shame and blame (2020), we discuss how ‘heaping blame on shame’ has become a ‘wilful political strategy’ under neoliberalism, particularly as it relates to individuals with obesity, and how the Tackling Obesity campaign leverages concerns around ‘choices’ and ‘costs’ as a means through which to encourage normative models of self-care and self-discipline.     

Butane detection after long-term treatment of burns in two autopsy cases

A man and a woman were rescued from a room that had exploded. Many empty cassette gas cylinders were found in the room. The man and woman were hospitalized immediately for the treatment of burns. The woman died 6 days later, and the man died 31 days later without regaining consciousness. Carbonization and hardening of the frontal facial skin and parts of the left and right fingers were observed on the man's body. In both cases, systemic burns had led to progressive systemic edema and markedly suppressed circulation. Analytical samples for butanes obtained from their bodies at autopsy were stored at −20 °C for 14 and 25 days, respectively, before analysis. Normal butane and isobutane were quantified in the brain and subcutaneous adipose tissue of the woman. Only the isobutane was quantified in the adipose tissue of the man. The evidence suggests that the man lit a cigarette while breathing gas and the entire room exploded. Our results also suggest that butane can be detected in the adipose tissue of autopsy cases long after inhalation even under the present storage conditions, and isobutane may remain in adipose tissue longer than n-butane.     

健脾益肝方对非酒精性脂肪性肝病患者脂肪分布及脂代谢的影响

目的:探讨健脾益肝方对非酒精性脂肪性肝病(NAFLD)患者脂肪分布及脂代谢的影响。方法:将80例NAFLD患者随机分为对照组和治疗组各40例。两组患者均在多学科联合管理下给予个体化的饮食、运动等生活方式指导,治疗组患者在此基础上加用健脾益肝方,疗程均为3个月。通过生物电阻抗技术测量患者治疗前后脂肪质量及分布,定期监测肝肾功能、血脂指标。比较两组患者肥胖、脂肪分布、血脂指标变化。结果:治疗组患者有效率为97.5%,明显高于对照组的82.5%,差异有统计学意义(P<0.05);治疗组患者BMI、BFP、WHR、TC、TG及LDL-C水平明显低于对照组,差异有统计学意义(均P<0.05);治疗组患者躯干及内脏脂肪沉积改善明显优于对照组,差异有统计学意义(均P<0.05)。结论:生活方式干预联合健脾益肝方治疗NAFLD患者能显著改善患者的肥胖及脂代谢紊乱,并且与躯干和内脏脂肪质量的下降密切相关。     

Dietary fat intake and metabolic syndrome in adults: A systematic review

Background and aimsThe metabolic syndrome (MetS) is a cluster of coexisting cardiovascular risk factors. The role of specific dietary fats was reemphasized by dietary recommendations. This systematic review aims to assess evidence for the effect of dietary fat intake on MetS occurrence and reversion in adults.Methods and ResultsThe MEDLINE database was used to search the existing literature. We included observational studies that analyzed dietary fat intake in adults with MetS and clinical trials that compared the effects of different dietary fat diets on MetS and/or its components. Thirty articles were selected (14 observational and 16 clinical trials), and we included information of dietary fat and fatty acids as well as MetS, body mass index, cholesterol, hypertension, and diabetes in adults. SFA intake was found to be positively associated with MetS components. Most of the observational reviewed studies found beneficial associations between MUFA and PUFA (including n-3 and n-6 subtypes) intake and MetS components. Clinical trials also supported the benefits of MUFA- or PUFA-enriched diets (including low-fat diets) in reducing MetS.ConclusionsThe effects of dietary SFAs on MetS will be influenced by other specific nutrients. Replacement of SFA by MUFA and PUFA has been associated with a decrease in MetS. Dietary recommendations should emphasize on different qualities of fat intake, not only to reduce total fat intake, to obtain health benefits in adults.
