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.     

Étude de faisabilité : l’utilisation de l’imagerie médicale en éducation thérapeutique en radiothérapie

PurposeAssess the feasibility of a randomized controlled trial (RCT) exploring the use of medical imaging as a therapeutic education (TPE) intervention in external radiation therapy.Materials and methodsExperimental feasibility trial of “RCT” type carried out in a single-center, between November 2019 and March 2020, following adult patients treated by thoracic radiotherapy. In addition to the information usually given, the experimental group benefited from an intervention consisting in the visualization of their own medical images using the open-source software “Stone of Orthanc”.ResultsForty-nine patients were recruited with a refusal rate of 8.16% (4/49). 20 patients were withdrawn from the study for health reasons (COVID), 10 for medical reasons. All the remaining 15 participants completed the process. Although not significant, the experimental group showed a median gain in the perception of knowledge compared to the control group (+ 1.9 (1.6 – 2.2)) vs (+ 1.4 (1.4 – 1.8)), as well as a decrease in scores related to anxiety (? 3.0 (?4.5 - (?2.0)) vs ? 1.0 (?5.0 - 0.0)) and emotional distress ((? 5.0 (? 7.5 - (? 3.5)) vs (? 2.0 (? 5.0 - (? 1.0)) A significant reduction (p = 0.043) is observed for the depression score ((? 2.0 (?3.0 - (?1.5)) vs (0.0 (0.0 – 0.0)).ConclusionThis study demonstrates the feasibility of the project, with promising preliminary results. Some adaptations in order to conduct a larger-scale RCT are highlighted.

Relationships between electrochemical skin conductance and kidney disease in Type 2 diabetes

BackgroundSUDOSCAN® non-invasively measures peripheral small fiber and autonomic nerve activity using electrochemical skin conductance. Since neuropathy and nephropathy are microvascular Type 2 diabetes (T2D) complications, relationships between skin conductance, estimated glomerular filtration rate (eGFR), and urine albumin:creatinine ratio (UACR) were assessed.MethodsTwo hundred five African Americans (AA) with T2D, 93 AA non-diabetic controls, 185 European Americans (EA) with T2D, and 73 EA non-diabetic controls were evaluated. Linear models were fitted stratified by population ancestry and T2D, adjusted for covariates.ResultsRelative to EA, AA had lower skin conductance (T2D cases p < 0.0001; controls p < 0.0001). Skin conductance was also lower in T2D cases vs. controls in each population (p < 0.0001, AA and EA). Global skin conductance was significantly associated with eGFR in AA and EA with T2D; adjusting for age, gender, BMI, and HbA1c, positive association was detected between skin conductance and eGFR in AA T2D cases (parameter estimate 3.38, standard error 1.2; p = 5.2E^− 3), without association in EA T2D cases (p = 0.22).ConclusionsNoninvasive measurement of skin conductance strongly associated with eGFR in AA with T2D, replicating results in Hong Kong Chinese. SUDOSCAN® may prove useful as a low cost, non-invasive screening tool to detect undiagnosed diabetic kidney disease in populations of African ancestry.     

MRI误诊的椎体海绵状血管瘤18F-FDG PET/CT显像一例

笔者报道了一例双下肢乏力4月余，加重伴疼痛、活动受限一周的病例。MRI显示病灶累及胸3椎体、椎体附件和周围组织，并延伸到椎管内硬脊膜，增强后病变明显强化，MRI因病变范围广且增强后明显强化，考虑为恶性肿瘤。而18F-FDG PET低代谢结合CT点状、栅栏状钙化灶和椎体骨质无破坏，考虑为海绵状血管瘤；且术后病理因病灶内见异常血管聚集成丛状，血管腔内有大量红细胞，诊断为海绵状血管瘤。文献复习加深了对椎体海绵状血管瘤的认识，其可累及椎体、椎体附件，甚至延伸到椎管内和（或）周围组织。海绵状血管瘤是一种血管畸形，MRI增强后呈明显强化，但是PET显像则呈低代谢。当MRI显示病变范围广伴明显强化，而椎体无骨质破坏，怀疑恶性肿瘤时，应结合PET/CT对诸如海绵状血管瘤等良性病变进行鉴别诊断。     

Metabolic syndrome-related sarcopenia is associated with worse prognosis in patients with gastric cancer: A prospective study

ObjectivesSarcopenia and metabolic syndrome (MetS) are associated with the prognosis from malignant tumors. However, evidence of the relationship between sarcopenia and MetS among gastric cancer (GC) patients following radical gastrectomy is lacking. This study assessed the association between preoperative sarcopenia and MetS among GC patients and analyzed the prognosis of patients with different malnutrition statuses.MethodsWe prospectively assessed the preoperative statuses of sarcopenia and MetS among patients who underwent radical gastrectomy from July 2014 to December 2017. We combined sarcopenia and MetS to generate four groups: MetS-related sarcopenia group (MSS), sarcopenia group (S), MetS group (MS), and normal group (N).ResultsA total of 749 patients with resectable GC were included in this study. Preoperative MetS was associated with sarcopenia (p < 0.001). Multivariate logistic regression presented that MetS-related sarcopenia (OR = 2.445; p = 0.010) and sarcopenia alone (OR = 2.117; p = 0.001) were independent predictors of grade Ⅱ and above complications, while MetS alone was not (p = 0.342). Cox regression analysis revealed that MetS-related sarcopenia led to the worst prognosis in the four groups (MSS vs MS: HR = 3.555, p < 0.001; MSS vs N: HR = 2.020, p = 0.003; MSS vs S: HR = 1.763, p = 0.021). However, the MetS group had better prognosis than the normal group (MS vs N: HR = 0.568, p = 0.048).ConclusionPreoperative MetS was associated with sarcopenia among GC patients. MetS-related sarcopenia resulted in a significantly worse prognosis. The long-term prognoses of patients with sarcopenia were impaired by preoperative MetS, while patients without sarcopenia benefited. Thus, patients with both sarcopenia and MetS require more medical interventions.     

Development and validation of the stigma scale for epilepsy in Turkey

ObjectiveEpilepsy is a chronic disease with an increased risk of stigma. The aim of this study was to investigate the efficacy of a scale developed by the authors to determine the level of stigma in Turkish patients with epilepsy and their relatives.MethodsIn this pilot study, two scales were developed, one consisting of 32 questions for the patients and one of 20 questions for the patients' relatives. Initially, a total of 30 patients with epilepsy and 30 relatives of the patients were included. The Cronbach's alpha coefficient was calculated in a reliability analysis of validity applying the scales to 302 patients and 201 relatives of the patients. The Pearson correlation coefficient was used for the reliability analysis of the test-retest. The t-test was used in paired series, and factor analysis was conducted. The correlation between the clinical and demographical data and the stigma scores was evaluated.ResultsThe scales were applied to participants twice under the same conditions in one-week interval. In the test-retest analysis, the internal consistency of the scales was high and reliable. In the analysis of the patients, the Cronbach's alpha value of the scale was found to be 0.915. In the factor analysis, the questions were grouped into five factors including social isolation, discrimination, insufficiency, false beliefs, and stigma resistance. The factors with the highest contribution to the stigma level were social isolation and discrimination. In the stigma scores, a significant correlation was found between the age of the patient, frequency of seizures, education status, level of income, and the amount of antiepileptic drugs used. In the analysis of the patients' relatives, the Cronbach's alpha value of the scale was found to be 0.892. In the factor analysis, the questions were classified as discrimination, prejudgments, and false beliefs. The factor which most contributed to the stigma level was discrimination. A significant correlation was found in the stigma scores between sex, education status, marital status, and income distribution.ConclusionAccording to our study results, it is clearly seen that both patients and their relatives suffer from epilepsy-associated stigma. Patients with epilepsy and their relatives are faced with discrimination in society, resulting in social isolation. We, therefore, believe that both patients and their relatives should be informed in detail about discrimination to overcome this challenge.
