1Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis.Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg 2017World Journal of Hepatology2017,9,7:11
2Research advances on the multiple uses of Moringa oleifera: a sustainable alternative for socially neglected population显示文摘Moringa oleifera Lam(Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for their coagulation, flocculation and sedimentation properties, their ability of improving water quality, by reducing organic matter and microbial load, with special applicability in intensive animal production systems, such as aquaculture. In addition, due to its high nutritional value and several medicinal properties, this tree may act as a nutritional and medical alternative for socially neglected populations. In this context, this review gathers information on M. oleifera, emphasizing its chemical constituents, nutritional, pharmacological and antimicrobial properties, applications in the treatment of water effluents, and ecological and social aspects.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Vandbergue Santos Pereira Débora de Souza Collares Maia Castelo-Branco Rossana de Aguiar Cordeiro Célia Maria de Souza Sampaio Manoel de Araújo Neto Paiva Joao Bosco Feitosa dos Santos JoséJúlio CostaSidrim Marcos Fábio Gadelha Rocha 2017Asian Pacific Journal of Tropical Medicine2017,10,7:10
3Open abdomen in gastrointestinal surgery:Which technique is the best for temporary closure during damage control?显示文摘AIM To compare the 3 main techniques of temporary closure of the abdominal cavity,vacuum assisted closure(vacuum-assisted closure therapy- VAC),Bogota bag and Barker technique,in damage control surgery.METHODS After systematic review of the literature,33 articles were selected to compare the efficiency of the three procedures.Criteria such as cost,infections,capacity of reconstruction of the abdominal wall,diseases associated with the technique,among others were analyzed.RESULTS The Bogota bag and Barker techniques present as advantage the availability of material and low cost,what is not observed in the VAC procedure.The VAC technique is the most efficient,not only because it reduces the tension on the boarders of the lesion,but also removes stagnant fluids and debris and acts at cellular level increasing cell proliferation and division.Bogota bag presents the higher rates of skin laceration and evisceration,greater need for a stent for draining fluids and wash-ups,higher rates of intestinal adhesion to the abdominal wall.The Barker technique presents lack of efficiency in closing the abdominal wall and difficulty on maintaining pressure on the dressing.The VAC dressing can generate irritation and dermatitis when the drape is applied,in addition to pain,infection and bleeding,as well as toxic shock syndrome,anaerobic sepsis and thrombosis.CONCLUSION The VAC technique,showed to be superior allowing a better control of liquid on the third space,avoiding complications such as fistula with small mortality,low infection rate,and easier capability on primary closure of the abdominal cavity.Marcelo A F Ribeiro Junior Emily Alves Barros Sabrina Marques de Carvalho Vinicius Pereira Nascimento José Cruvinel Neto Alexandre Zanchenko Fonseca 2016World Journal of Gastrointestinal Surgery2016,8,8:9

6代谢型谷氨酸受体可作为一种新型恶性胶质瘤治疗靶点(英文)显示文摘Objective Metabotropic glutamate receptors(mG luR)are predominantly involved in maintenance of cellular homeostasis of central nervous system.However,evidences have suggested other roles of mG luR in human tumors.Aberrant mG luR signaling has been shown to participate in transformation and maintenance of various cancer types,including malignant brain tumors.This review intends to summarize recent findings regarding the involvement of mG luR-mediated intracellular signaling pathways in progression,aggressiveness,and recurrence of malignant gliomas,mainly glioblastomas(GBM),highlighting the potential therapeutic applications of mG luR ligands.In addition to the growing number of studies reporting mG luR gene or protein expression in glioma samples(resections,lineages,and primary cultures),pharmacological blockade in vitro of mG luR1 and mG luR3 by selective ligands has been shown to be anti-proliferative and anti-migratory,decreasing activation of MAPK and PI3K pathways.In addition,mG luR3 antagonists promoted astroglial differentiation of GBM cells and also enabled cytotoxic action of temozolomide(TMZ).mG luR3-dependent TMZ toxicity was supported by increasing levels of MGMT transcripts through an intracellular signaling pathway that sequentially involves PI3K and NF-κB.Further,continuous pharmacological blockade of mG luR1 and mG luR3 have been shown to reduced growth of GBM tumor in two independent in vivo xenograft models.In parallel,low levels of mG luR3 mRNA in GBM resections may be a predictor for long survival rate of patients.Since several Phase I,II and III clinical trials are being performed using group I and II mG luR modulators,there is a strong scientifically-based rationale for testing mG luR antagonists as an adjuvant therapy for malignant brain tumors.Pereira MS Klamt F Thomé CC Worm PV de Oliveira DL 2017中华神经外科疾病研究杂志2017,16,1:3
