1Recruitment maneuvers in acute respiratory distress syndrome: The safe way is the best way显示文摘Acute respiratory distress syndrome(ARDS) represents a serious problem in critically ill patients and is associated with in-hospital mortality rates of 33%-52%. Recruitment maneuvers(RMs) are a simple, low-cost, feasible intervention that can be performed at the bedside in patients with ARDS. RMs are characterized by the application of airway pressure to increase transpulmonary pressure transiently. Once non-aerated lung units are reopened, improvements are observed in respiratory system mechanics, alveolar reaeration on computed tomography, and improvements in gas exchange(functional recruitment). However, the reopening process could lead to vascular compression, which can be associated with overinflation, and gas exchange may not improve as expected(anatomical recruitment). The purpose of this review was to discuss the effects of different RM strategies- sustained inflation, intermittent sighs, and stepwise increases of positive end-expiratory pressure(PEEP) and/or airway inspiratory pressure- on the following parameters: hemodynamics, oxygenation, barotrauma episodes, and lung recruitability through physiological variables and imaging techniques. RMs and PEEP titration are interdependent events for the success of ventilatory management. PEEP should be adjusted on the basis of respiratory system mechanics and oxygenation. Recent systematic reviews and meta-analyses suggest that RMs are associated with lower mortality in patients with ARDS. However, the optimal RM method(i.e., that providing the best balance of benefit and harm) and the effects of RMs on clinical outcome are still under discussion, and further evidence is needed.Raquel S Santos Pedro L Silva Paolo Pelosi Patricia RM Rocco 2015World Journal of Critical Care Medicine2015,4,4:19
2Phase 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
3Watch and wait approach in rectal cancer:Current controversies and future directions显示文摘According to the main international clinical guidelines,the recommended treatment for locally-advanced rectal cancer is neoadjuvant chemoradiotherapy followed by surgery.However,doubts have been raised about the appropriate definition of clinical complete response(cCR)after neoadjuvant therapy and the role of surgery in patients who achieve a cCR.Surgical resection is associated with significant morbidity and decreased quality of life(QoL),which is especially relevant given the favourable prognosis in this patient subset. Accordingly, therehas been a growing interest in alternative approaches with less morbidity,including the organ-preserving watch and wait strategy, in which surgery isomitted in patients who have achieved a cCR. These patients are managed with aspecific follow-up protocol to ensure adequate cancer control, including the earlyidentification of recurrent disease. However, there are several open questionsabout this strategy, including patient selection, the clinical and radiologicalcriteria to accurately determine cCR, the duration of neoadjuvant treatment, therole of dose intensification (chemotherapy and/or radiotherapy), optimal followupprotocols, and the future perspectives of this approach. In the present review,we summarize the available evidence on the watch and wait strategy in thisclinical scenario, including ongoing clinical trials, QoL in these patients, and thecontroversies surrounding this treatment approach.Fernando López-Campos Margarita Martín-Martín Roberto Fornell-Pérez Juan Carlos García-Pérez Javier Die-Trill Raquel Fuentes-Mateos Sergio López-Durán JoséDomínguez-Rullán Reyes Ferreiro AlejandroRiquelme-Oliveira Asunción Hervás-Morón Felipe Couñago 2020World Journal of Gastroenterology2020,26,29:10
4High prevalence of viable Mycobacterium avium subspecies paratuberculosis in Crohn's disease显示文摘AIM:To examine the detection rate of viable Mycobacterium avium subspecies paratuberculosis(MAP) in patients with inflammatory bowel disease [Crohn's disease(CD) and ulcerative colitis(UC)].METHODS:Thirty patients with CD(15 with at least one NOD2/CARD15 mutation),29 with UC,and 10 with no inflammatory bowel disease(IBD).were tested for MAP by polymerase chain reaction(specific IS900 fragment) and blood culture.RESULTS:MAP DNA was detected in all original blood samples and 8-wk blood cultures(CD,UC and non-IBD).Positive MAP DNA status was confirmed by dot blot assays.All 69 cultures were negative by acid-fast Ziehl-Neelsen staining.Viable MAP,in spheroplast form,was isolated from the 18-mo blood cultures of all 30 CD patients,one UC patient,and none of the non-IBD controls.No association was found between positive MAP cultures and use of immunosuppressive drugs or CDassociated single nucleotide polymorphisms.CONCLUSION:MAP is widely present in our area and MAP DNA can be recovered from the blood of CD,UC and non-IBD patients.However,MAP spheroplasts were only found in CD patients.Juan L Mendoza Amparo San-Pedro Esther Culebras Raquel Cíes Carlos Taxonera Raquel Lana Elena Urcelay Fernando de la Torre Juan J Picazo Manuel Díaz-Rubio 2010World Journal of Gastroenterology2010,16,36:5
5Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration.Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima 2018World Journal of Gastroenterology2018,24,38:3
6Toxoplasmosis among pregnant women:High seroprevalence and risk factors in Kinshasa,Democratic Republic of Congo显示文摘Objective:To determine the seroprevalence of toxoplasmosis in pregnant women,as well as the proportion of acutely infected and risk factors in the Democratic Republic of Congo.Methods:Thirty maternities in Kinshasa were randomly selected and women attending antenatal consultation were invited to participate.They were interviewed with a structured questionnaire about known risk factors(age,meat consumption,contact with soil,and presence of cat)and a venous blood sample was taken.Sera were analysed for total immunoglobulins(Ig)by VIDAS Toxo Competition using Enzyme Linked Fluorescent Assay.IgM was determined by VIDIA Toxo IgM and IgG avidity by VIDAS Toxo IgG avidity.Results:A total of 781 women were included.Median age was 28 years old(IQR:8.S).And 627women(80.3%;95%CI:77.5-83.1)were found to be positive to total Ig and 17 out of 387(4.4%;95%CI:2.3-6.4)were positive to IgM.IgC avidity was low for 2(11.8%)women,intermediate for 2(11.8%)and high for 13 women(76.4%).There was no statistically significant association between Toxoplasma gondii infection and any risk factors assessed.Conclusion:In Kinshasa,toxoplasmosis endemicity is highly prevalent.One woman out of twenty five had a recent toxoplasmosis infection and 20%were not protected against primoinfection,indicating a need for measures to prevent and control toxoplasmosis during pregnancy.Doudou Yobi Renaud Piarroux Coralie L'Ollivier Jacqueline Franck Hypolite Situakibanza Hypolite Muhindo Patrick Mitashi Raquel Andreia Inocencio da Luz Marc Van Sprundel Marleen Boelaert Jean-Pierre Van Geertruyden Pascal Lutumba 2014Asian Pacific Journal of Tropical Biomedicine2014,4,1:2
7Laparoscopic gastrojejunostomy for gastric outlet obstruction in patients with unresectable hepatopancreatobiliary cancers: A personal series and systematic review of the literature显示文摘The major symptoms of advanced hepatopancreaticbiliary cancer are biliary obstruction, pain and gastric outlet obstruction(GOO). For obstructive jaundice, surgical treatment should de consider in recurrent stent complications. The role of surgery for pain relief is marginal nowadays. On the last, there is no consensus for treatment of malignant GOO. Endoscopic duodenal stents are associated with shorter length of stay and faster relief to oral intake with more recurrent symptoms. Surgical gastrojejunostomy shows better long-term results and lower re-intervention rates, but there are limited data about laparoscopic approach. We performed a systematic review of the literature, according PRISMA guidelines, to search for articles on laparoscopic gastrojejunostomy for malignant GOO treatment. We also report our personal series, from 2009 to 2017. A review of the literature suggests that there is no standardized surgical technique either standardized outcomes to report. Most of the studies are case series, so level of evidence is low. Decisionmaking must consider medical condition, nutritional status, quality of life and life expectancy. Evaluation ofthe patient and multidisciplinary expertise are required to select appropriate approach. Given the limited studies and the difficulty to perform prospective controlled trials, no study can answer all the complexities of malignant GOO and more outcome data is needed.Alba Manuel-Vázquez Raquel Latorre-Fragua Carmen Ramiro-Pérez Aylhin López-Marcano Roberto De la Plaza-Llamas José Manuel Ramia 2018World Journal of Gastroenterology2018,24,18:2

10Role of diet and nutrition in inflammatory bowel disease显示文摘Inflammatory bowel diseases(IBDs)are closely linked to nutrition.The latest research indicates that diet and nutrition are significantly involved in the etiopathogenesis of the disease,although their specific role throughout its clinical course still remains unclear.This study reviewed how diet and nutrition are associated with IBD development and management.Even though specific diets have been shown to bring about positive outcomes,there is currently no scientific consensus regarding an appropriate diet that would benefit all IBD patients.We suggest that individualized dietary recommendations are of the greatest importance and that diets should be planned to provide individual IBD patients with specific nutrient requirements while keeping all the clinical aspects of the patients in mind.Further research is clearly necessary to investigate nutritional factors involved in IBD development and,especially,to evaluate the applications of the diets during the course of the disease.Marina Moreira de Castro Lívia Bitencourt Pascoal Karine Mariane Steigleder Beatriz Piatezzi Siqueira Ligiana Pires Corona Maria de Lourdes Setsuko Ayrizono Marciane Milanski Raquel Franco Leal 2021World Journal of Experimental Medicine2021,11,1:2

13Higher rates of autism and attention deficit/hyperactivity disorder in American children:Are food quality issues impacting epigenetic inheritance?显示文摘In the United States,schools offer special education services to children who are diagnosed with a learning or neurodevelopmental disorder and have difficulty meeting their learning goals.Pediatricians may play a key role in helping children access special education services.The number of children ages 6-21 in the United States receiving special education services increased 10.4%from 2006 to 2021.Children receiving special education services under the autism category increased 242%during the same period.The demand for special education services for children under the developmental delay and other health impaired categories increased by 184%and 83%respectively.Although student enrollment in American schools has remained stable since 2006,the percentage distribution of children receiving special education services nearly tripled for the autism category and quadrupled for the developmental delay category by 2021.Allowable heavy metal residues remain persistent in the American food supply due to food ingredient manufacturing processes.Numerous clinical trial data indicate heavy metal exposures and poor diet are the primary epigenetic factors responsible for the autism and attention deficit hyperactivity disorder epidemics.Dietary heavy metal exposures,especially inorganic mercury and lead may impact gene behavior across generations.In 2021,the United States Congress found heavy metal residues problematic in the American food supply but took no legislative action.Mandatory health warning labels on select foods may be the only way to reduce dietary heavy metal exposures and improve child learning across generations.Renee J Dufault Raquel A Crider Richard C Deth Roseanne Schnoll Steven G Gilbert Walter J Lukiw Amanda L Hitt 2023World Journal of Clinical Pediatrics2023,12,2:1
