“…To measure total abdominal and visceral fat areas, a 5-mm CT slice scan was acquired at the L3-L4 level with the subject at supine position [21]. The region of interest was from − 250 to − 50 Hounsfield unit [22,23]. The visceral fat area was defined by the internal aspect of the abdominal and oblique muscle walls surrounding the cavity and the posterior aspect of the vertebral body.…”

Background Pylorus-preserving gastrectomy (PPG) is commonly performed for early gastric cancer (EGC) located in middle third of the stomach. We investigated the surgical, oncological, and functional outcomes of PPG involving the upper third of stomach. Methods We included all patients of the period 2013-2016 who underwent PPG, distal subtotal gastrectomy (DSG), and total gastrectomy (TG) for EGC involving the upper third by carefully defining the localization. Surgical, oncological, and functional outcome analyses included postoperative morbidity, lymph-node metastasis, tumor recurrence, postoperative body weight, body mass index, hemoglobin, total protein, albumin, quantification of intraabdominal fat, and gallstone development.Results Overall, 288 cases were analyzed: 145 PPG, 61 DSG, and 82 TG. In the study period, patients potentially underwent PPG for EGC involving the upper third, if enough proximal remnant stomach was found whilst achieving a sufficient proximal margin. PPG resulted in less operation time (p < 0.001), less blood loss (p = 0.002) and lower postoperative morbidity compared to TG. For lymph-node (LN) stations being resected in all groups, no difference was found in number of resected LN. Recurrence-free survival was similar for all groups. PPG showed advantages regarding postoperative body weight, hemoglobin, total protein, albumin in postoperative 6 and 12 month follow-up. Lowest decrease of abdominal fat area after 12 months was seen for PPG. Gallstone incidence was significantly lower after PPG compared to TG (p < 0.001). Conclusions For EGC involving the upper third, PPG can be another good option with lower postoperative morbidity, better functional outcomes, and same oncological safety.

“…The authors suggest that this method could replace the expensive and more commonly used method of DXA. Interestingly, in another study, Mauad et al 13 tested the accuracy and reproducibility of measuring abdominal adiposity by DMS and CT and identified an increased intraobserver reliability in DMS. However, both DMS and CT showed high accuracy and good reproducibility when measuring abdominal adiposity.…”

Approximately 93 million adults and over 13 million children and adolescents across the United States are considered overweight or obese. 1 Health care expenditures are shown to be 81% greater in obese adults versus those of normal weight. 2,3 The prevalence of type 2 diabetes and hypertension has steadily increased in the United States, with metabolic syndrome rates estimated at more than 30%. 4 Due to the increased risk for metabolic conditions in America's obese populations, identifying patients at risk with a reliable and practical tool is vital to providing preventive health measures. Given the link between abdominal adiposity and metabolic syndrome, determining an individual's risk for disease by measuring abdominal adiposity is greatly needed. The use of diagnostic medical sonography (DMS) has been shown to be a reliable and easily accessible tool when measuring abdominal adiposity. 5 DMS is an indirect imaging tool that could be used in correlation with other measures to help determine an individual's risk for metabolic syndrome. The value of DMS for gauging abdominal obesity and the risk for metabolic disease is that it is relatively inexpensive, noninvasive, and a validated indirect assessment tool. DMS has the ability to measure increased abdominal adiposity and monitor changes in body composition. 5 The use of DMS could be a more feasible and advantageous tool for routine clinical 848746J DMXXX10.

ПЕРЕДОВАЯ СТАТЬЯВ большинстве стран мира ожирение сегодня ста-новится одним из основных факторов риска развития и прогрессирования хронических неинфекционных заболеваний [1], что во многом обусловлено посто-янно растущими показателями его распространенно-сти [2]. При этом в структуре нозологических единиц, ассоциированных с наличием избыточной массы тела и ожирения, лидирует кардиоваскулярная патология: из ежегодных четырёх миллионов смертей в мире, связанных с высоким индексом массы тела (ИМТ), более двух третей являются случаями сердечно-сосу-дистой смерти [3].Российскую Федерацию, характеризующуюся высокой частотой встречаемости основных факторов сердечно-сосудистого риска (ССР), среди которых ожирение занимает лидирующую третью позицию (29,7% по данным эпидемиологического исследова-ния ЭССЕ-РФ 2012-2013гг [4]), отличает высокий показатель сердечно-сосудистой смертности, превы-шающий более чем в 2,5 раза аналогичный в странах Евросоюза, что определяет одну из главных задач национальной системы здравоохранения -профи-лактику сердечно-сосудистых заболеваний (ССЗ) и их осложнений, направленную на предупреждение, Ожирение становится одним из основных факторов риска развития и прогрес-сирования сердечно-сосудистых заболеваний. Ассоциация высоких значений индекса массы тела с общей и сердечно-сосудистой смертностью подтверж-дается результатами мета-анализов многочисленных проспективных исследо-ваний. С другой стороны, две наиболее глобальные проблемы, касающиеся данной взаимосвязи, -"парадокс ожирения" и гетерогенность фенотипов ожирения в отношении кардиометаболического риска, вызвали многочислен-ные дискуссии по вопросам прогностического влияния избыточной массы тела и ожирения и целесообразности их коррекции у пациентов в рамках вто-ричной профилактики. Сегодня стал очевидным факт максимальной роли в увеличении риска при ожирении определенного характера распределения жировой ткани, преобладания висцерального жира, морфологических изме-нений висцеральной жировой ткани в рамках процессов ремоделирования и воспаления с последующим развитием ее дисфункции. В данной статье дается оценка этиопатогенетической роли висцеральной жировой ткани в кар-диоваскулярном континууме, приводится обзор методов верификации висце-рального ожирения, а также предлагается концепция стратификации кардио-васкулярного риска, ассоциированного с ожирением, в широкой клинической практике. Obesity becomes one of the main risk factors of development and progression of cardiovascular diseases. Association of the high values of body mass index with overall and cardiovascular mortality is confirmed by the results of meta-analyses of multiple prospective studies. On the other hand, the two most global problems of this relationship -"obesity paradox" and heterogeneity of obesity phenotypes by cardiometabolic risk, released multiple discussions on the issues of predictive value of body overweight and obesity, and worth of correction in patients under the secondary prevention framework. Nowadays, the fact became obvious that maximum role in the risk r...
