RESUMO

BACKGROUND: The periconceptional period is a critical window for the origins of adverse pregnancy and birth outcomes, yet little is known about the dietary patterns that promote perinatal health. OBJECTIVE: We used machine learning methods to determine the effect of periconceptional dietary patterns on risk of preeclampsia, gestational diabetes, preterm birth, small-for-gestational-age (SGA) birth, and a composite of these outcomes. METHODS: We used data from 8259 participants in the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (8 US medical centers, 2010‒2013). Usual daily periconceptional intake of 82 food groups was estimated from a food frequency questionnaire. We used k-means clustering with a Euclidean distance metric to identify dietary patterns. We estimated the effect of dietary patterns on each perinatal outcome using targeted maximum likelihood estimation and an ensemble of machine learning algorithms, adjusting for confounders including health behaviors and psychological, neighborhood, and sociodemographic factors. RESULTS: The 4 dietary patterns that emerged from our data were identified as "Sandwiches and snacks" (34% of the sample); "High fat, sugar, and sodium" (29%); "Beverages, refined grains, and mixed dishes" (21%); and "High fruits, vegetables, whole grains, and plant proteins" (16%). One-quarter of pregnancies had preeclampsia (8% incidence), gestational diabetes (5%), preterm birth (8%), or SGA birth (8%). Compared with the "High fat, sugar, and sodium" pattern, there were 3.3 to 4.3 fewer cases of the composite adverse outcome per 100 pregnancies among participants following the "Beverages, refined grains and mixed dishes" pattern (risk difference -0.043; 95% confidence interval -0.078, -0.009), "High fruits, vegetables, whole grains and plant proteins" pattern (-0.041; 95% confidence interval -0.078, -0.004), and "Sandwiches and snacks" pattern (-0.033; 95% confidence interval -0.065, -0.002). CONCLUSIONS: Our results highlight that there are a variety of periconceptional dietary patterns that are associated with perinatal health and reinforce the negative health implications of diets high in fat, sugars, and sodium.

RESUMO

INTRODUCTION AND IMPORTANCE: Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare, and the clinical symptoms, test results, and imaging characteristics are nonspecific in most patients; thus, it is difficult to differentiate from other liver masses before surgery. Histopathology and immunohistochemistry are the main basis for the diagnosis. PHNETs and colon tumors co-occur in a patient and are non-homologous, as reported in the English-language literature for the first time. CASE PRESENTATION: We present a case of a 60-year-old woman with right hepatic lobe mass accidentally discovered on abdominal ultrasonography during a routine examination. Preoperative liver contrast-enhanced computed tomography suggested hepatocellular carcinoma; then, surgery were performed. Pathological results revealed a Grade 2 neuroendocrine tumor of the liver. In search of the primary tumor, upper and lower endoscopy of the GI tract was performed and revealed a mass in the ascending colon. Ascending colon cancer was considered; then, laparoscopic right hemicolectomy was performed. Pathological results suggested tubular villous adenoma of the ascending colon. The final diagnosis was not colon cancer with liver metastases but was PHNETs with colon adenoma. CLINICAL DISCUSSION: PHNETs are rare cancers that are difficult to diagnose, requiring not only differentiation from other liver masses but also exclusion of metastases from extrahepatic sources. The pathological results play an important in making an accurate diagnosis. CONCLUSION: Pathology, postoperative follow-up, and comprehensive imaging examinations are powerful tools in the diagnosis of PHNETs. Currently, surgery is the best treatment to achieve a potential cure and prolong the patient's survival.

RESUMO

PEGylation has been widely used to improve the pharmacokinetic properties of prodrug self-assembled nanoparticles (prodrug-SANPs). However, the impacts of the amount of PEG on the self-assemble stability, cellular uptake, pharmacokinetics, and antitumor efficacy of prodrug-SANPs are still unknown. Herein, selenoether bond bridged docetaxel dimeric prodrug was synthesized as the model prodrug. Five prodrug-SANPs were designed by using different mass ratios of prodrugs to PEG (Wprodrug/WDSPE-mPEG2000 = 10:0, 9:1, 8:2, 7:3 and 6:4), and defined as Pure drug NPs, 9:1NPs, 8:2NPs, 7:3 NPs and 6:4 NPs, respectively. Interestingly, 8:2 NPs formed the most compact nanostructure, thus improving the self-assemble stability and pharmacokinetics behavior. In addition, the difference of these prodrug-SANPs in cellular uptake was investigated, and the influence of PEG on cytotoxicity and antitumor efficacy was also clarified in details. The 8:2 NPs exhibited much better antitumor efficacy than other prodrug-SANPs and even commercial product. Our findings demonstrated the pivotal role of the amount of PEG on prodrug-SANPs.

RESUMO

Recently, the interventional therapies are used more often in clinical practice for hepatocellular carcinoma. The most commonly used methodologies include radiofrequency ablation, microwave ablation, laser ablation, and cryotherapy. Most of the interventional operations need local anesthesia combined with intravenous sedation. Also, some interventional therapy centers apply general anesthesia. However, different anesthesia methods can cause diverse effects on patients' pain management, recovery time, and hospitalization time. For the better understanding of the current anesthesia application status, we summarize and analyze multiple anesthesia methods while being applied in interventional therapy for hepatocellular carcinoma; in addition, their characters are also compared in this paper.
