Risk factors and a simple scoring system for predicting bowel resection in infants with NEC

Background and aimsWe intended to investigate the predictors for bowel resection in infants with necrotizing enterocolitis (NEC). We further developed a scoring system for better predicting bowel resection.MethodsA total of 207 infants who underwent surgical management at Children's Hospital, Chongqing Medical University between April 2008 and December 2020 were identified for the following investigation. Bowel resection was reviewed among the infants who underwent the procedure. Potential parameters related to bowel resection were explored using a multiple logistic regression method, and then a scoring system was developed.ResultsAmong the 207 patients who underwent operative intervention that were reviewed, 109 infants underwent bowel resection. Multivariate logistic regression analysis showed that birth weight, hypotension, neutropenia, pneumoperitoneum, acidosis, and intestinal wall thickness were predictors related to the occurrence of bowel resection. A 6-point scoring system was further developed based on the obtained total coefficient, and the infants could be divided into low-, moderate- and high-risk groups according to cut values of 7 and 13.ConclusionThe results of this study demonstrated that severe NEC features and low birth weight were associated with bowel resection. The risk scoring system could accurately separate infants that were suspected to have bowel loss during surgery.     

Cancer; Pathophysiology and Stress Modulation (Cancer,Therapeutic Interventions)

ObjectiveThe purpose of this review is to describe the myriad complications of cancer and its therapies to emphasize the pathophysiological need for prehabilitation.Data SourcesThe information presented in this review is from applicable, peer-reviewed scientific articles.ConclusionCancer itself renders negative effects on the body, most notably unintentional weight loss and fatigue. Cancer treatments, especially surgical interventions, can cause detrimental short- and long-term impacts on patients, which translate to suboptimal treatment outcomes. Prehabilitation can be used to improve patient health prior to anticancer therapies to improve treatment tolerance and efficacy.Implications for Nursing PracticeNurses play an important role in the treatment of patients with cancer throughout the cancer care continuum. Many nurses are already aiding their patients in cancer prehabilitation through education. By describing common impairments amenable to multimodal prehabilitation, nurses may better advocate for their patients and can become even more involved in this aspect of care.

黄热病的再流行与世界卫生组织的消除黄热病流行战略

近年来,蚊虫传播的黄热病在非洲和南美洲地区大面积“再流行”,仅南美洲的巴西在一年时间就发现数千例黄热病确诊病例,黄热病已经在非洲和南美洲地区造成巨大的公共卫生负担。此外,在黄热病非流行国家和地区发现大量输入性病例,使得黄热病有可能在非洲和南美洲以外的地区成为“新发传染病”而在世界更大范围流行。为此,世界卫生组织制定了“消除黄热病流行（EYE）”战略,预计利用10年时间在黄热病流行地区接种13.8亿剂量黄热疫苗,以降低黄热病对国际公共卫生健康的危害。     

青岛市2018年1例疟疾死亡病例分析

目的 分析青岛市2018年1例输入性恶性疟的死亡原因,为预防疟疾死亡病例发生提供参考。方法 访谈接诊医生及患者家属,对患者病历和流行病学调查资料进行分析。结果 患者刘某,男,35岁,青岛市城阳区人,2018年3月19日到科特迪瓦务工,7月17日回国。25日患者到韩国办事,26日下午出现发冷、发热、出汗、头痛、浑身酸痛等症状,26—27日自服退烧药无好转,28日上午到韩国某医院就诊,未明确诊断,下午出现腹泻、呕吐症状,29日下午回国,14∶59到城阳区人民医院就诊,精神萎靡,经询问患者有非洲出国史可能患疟疾,16∶30将患者转诊至疟疾治疗定点医院,17∶50到达青岛市传染病医院时患者呈深昏迷状态,医生考虑患者病情危重且该院正在改建无ICU病房,建议转至有抢救条件的综合医院抢救。19:40患者转入海慈医疗集团ICU病房,21∶00被确诊为恶性疟,因病情危重,患者于30日14∶15死于多脏器功能衰竭。结论 对于输入性疟疾,根据流行病学史、临床症状和实验室检测结果尽早明确诊断,尽早使用抗疟药治疗,是避免出现死亡病例的关键。

Magnesium intake and primary liver cancer incidence and mortality in the Prostate,Lung, Colorectal and Ovarian Cancer Screening Trial

Epidemiological studies on magnesium intake and primary liver cancer (PLC) are scarce, and no prospective studies have examined the associations of magnesium intake with PLC incidence and mortality. We sought to clarify whether higher magnesium intake from diet and supplements was associated with lower risks of PLC incidence and mortality in the US population. Magnesium intake from diet and supplements was evaluated through a food frequency questionnaire in a cohort of 104,025 participants. Cox regression was employed to calculate hazard ratios for PLC incidence and competing risk regression was employed to calculate subdistribution hazard ratios for PLC mortality. Restricted cubic spline regression was employed to test nonlinearity. We documented 116 PLC cases during 1,193,513.5 person-years of follow-up and 100 PLC deaths during 1,198,021.3 person-years of follow-up. Total (diet + supplements) magnesium intake was found to be inversely associated with risks of PLC incidence (hazard ratio_{tertile 3 vs. 1}: 0.44; 95% confidence interval: 0.24, 0.80; p_trend = 0.0065) and mortality (subdistribution hazard ratio_{tertile 3 vs. 1}: 0.37; 95% confidence interval: 0.19, 0.71; p_trend = 0.0008). Similar results were obtained for dietary magnesium intake. Nonlinear inverse dose–response associations with PLC incidence and mortality were observed for both total and dietary magnesium intakes (all p_nonlinearity < 0.05). In summary, in the US population, a high magnesium intake is associated with decreased risks of PLC incidence and mortality in a nonlinear dose–response manner. These findings support that increasing the consumption of foods rich in magnesium may be beneficial in reducing PLC incidence and mortality.
