1Epidemiological Evolution of Lung Cancer in the South of Spain from 1990 to 2010显示文摘Background: Changes in lung cancer has been characterized by the increase of cases among women and the increase in adenocarcinomas among other histological subtypes.Methods: Descriptive analysis of cases diagnosed with lung cancer in Hospital Virgen de las Nieves(Spain) from 1990 to 2010,based on five variables(age, sex, smoking, histology and pathological anatomy). The study establishes associations between these variables and compares the results with the literature.Results: 2,026 patients were diagnosed with lung cancer in this period; 1,838 were males(90.7%) and 188 women(9.3%); 1,892 patients(93.4%) were smokers or ex-smokers and 134(6.6%) had never smoked; the most frequent non-small cell histology types were squamous cell carcinoma and adenocarcinoma and it was the most frequent neoplasia in women and were associated with a lower tobacco consumption.Conclusion: The large majority of lung cancer cases is associated with a history of smoking tobacco and there are histopathological differences according to gender and cumulative tobacco smoke load.Alberto Caballero Vázquez Ana Dolores Romero Ortiz Jose Manuel González de Vega San Román Raimundo García del Moral Bernardino Alcázar Navarrete 2018中国肺癌杂志2018,21,1:17
2Factors influencing quality of bowel preparation for colonoscopy显示文摘Recent technological advances in colonoscopy have led to improvements in both image enhancement and procedural performance.However,the utility of these technological advancements remain dependent on the quality of bowel preparation during colonoscopy.Poor bowel preparation has been shown to be associated with lower quality indicators of colonoscopy performance,such as reduced cecal intubation rates,increased patient discomfort and lower adenoma detection.The most popular bowel preparation regimes currently used are based on either Polyethylene glycol-electrolyte,a non-absorbable solution,or aqueous sodium phosphate,a lowvolume hyperosmotic solution.Statements from various international societies and several reviews have suggested that the efficacy of bowel preparation regimes based on both purgatives are similar,although patients' compliance with these regimes may differ somewhat.Many studies have now shown that factors other than the type of bowel preparation regime used,can influence the quality of bowel preparation among adult patients undergoing colonoscopy.These factors can be broadly categorized as either patient-related or procedure-related.Studies from both Asia and the West have identified patient-related factors such as an increased age,male gender,presence of co-morbidity and socioeconomic status of patients to be associated with poor bowel preparation among adults undergoing routine out-patient colonoscopy.Additionally,procedure-related factors such as adherence to bowel preparation instructions,timing of bowel purgative administration and appointment waiting times for colonoscopy are recognized to influence the quality of colon cleansing.Knowledge of these factors should aid clinicians in modifying bowel preparation regimes accordingly,such that the quality of colonoscopy performance and delivery of service to patients can be optimised.Ronald V Romero Sanjiv Mahadeva 2013World Journal of Gastrointestinal Endoscopy2013,5,2:13
3Q-switching of waveguide lasers based on graphene/WS_2 van der Waals heterostructure显示文摘We report on the operation of passively Q-switched waveguide lasers at 1 μm wavelength based on a graphene∕WS_2 heterostructure as a saturable absorber(SA). The gain medium is a crystalline Nd:YVO_4 cladding waveguide produced by femtosecond laser writing. The nanosecond waveguide laser operation at 1064 nm has been realized with the maximum average output power of 275 m W and slope efficiency of 37%. In comparison with the systems based on single WS_2 or graphene SA, the lasing Q-switched by a graphene∕WS_2 heterostructure SA possesses advantages of a higher pulse energy and enhanced slope efficiency, indicating the promisingapplications of van der Waals heterostructures for ultrafast photonic devices.ZIQI LI CHEN CHENG NINGNING DONG CAROLINA ROMERO QINGMING LU JUN WANG JAVIER RODRíGUEZ VáZQUEZ DE ALDANA YANG TAN FENG CHEN 2017Photonics Research2017,5,5:7
4Addition of statins to the standard treatment in patients with cirrhosis:Safety and efficacy显示文摘This review summarizes the safety and efficacy of statins in patients with cirrhosis.Due to concerns about the safety of statins in patients with impaired liver function,they have recently been investigated as a potential treatment option in cirrhosis.The most clinically significant adverse event is statin-related myopathy,and this may be related to the high serum statin concentrations in the setting of severely impaired liver function.Rhabdomyolysis is the most serious and potentially life-threatening manifestation.It has recently been demonstrated that the recommended dose of simvastatin in patients with decompensated cirrhosis would be 20 mg/d because higher values,such as 40 mg/d,are associated with many adverse events,especially muscle injury.Likewise,simvastatin should not be administered to patients with Model for End-stage Liver Disease score>12 and/or Child-Pugh class C because of the high risk of severe muscle injury.Due to the pleiotropic effects,the focus on statins has shifted from being considered harmful to something useful.Through these effects,statins could prevent liver-related morbidity and mortality in cirrhotic patients.Observational studies in large populations of patients with cirrhosis have shown that treatment with statins to decrease high cholesterol levels was associated with a reduced risk of hepatic decompensation,hepatocellular carcinoma development and death.The few randomized controlled trials in patients with cirrhosis and portal hypertension showed that statins lower portal pressure,quite likely through a reduction in hepatic resistance.Another large randomized controlled trial in patients with variceal bleeding showed that simvastatin in addition to standard of care did not prevent rebleeding but improved survival rate.Despite these encouraging outcomes,the quality of the evidence regarding the use of statins is low or very low due to the observational characteristics of most of the studies involved.Therefore,it is advisable to perform further randomized controlled trials on a large series of patients with hard clinical endpoints,using different statin types and varying doses.The objectives would be to prevent liver-related morbidity and mortality rather than treating cirrhosis complications to take additional information that makes it possible to add statins to the standard of care of these patients.Alberto E Muñoz Florencia D Pollarsky Mónica Marino Mariano Cartier Horacio Vázquez Pablo Salgado Gustavo Romero 2021World Journal of Gastroenterology2021,27,28:4
5Chemical and spectroscopic characterization of humic substances from sediment and riparian soil of a highly polluted urban river (Suquía River, Cordoba, Argentina)显示文摘The Suquía River,the largest urban river in C ordoba(Argentina),has been severely polluted for decades.Actions must be taken to restore its environmental quality by managing riparian zones for increased water-self purification.The current study aimed to characterize organic matter(OM)dynamics and humic substances(HS)spectrochemical properties along the lower-middle basin of the Suquía River.Riparian soil(0e20 cm)and sediment(0e10 cm)samples were collected from a reference location(S1)and four polluted sites(S2eS5)during a low-flow period.The contents of soil and sedimentary OM and HS fractions were analyzed by wet oxidation,as well as HS Fourier transform infrared(FT-IR)and ultravioletevisible(UVeVis)spectrochemical properties.The OM and HS fractions from riparian soil were high upstream of C ordoba City(S1 and S2,50.2e50.4 g/kg OM)and within a 50 km downstream location(S5,30.9 g/kg OM)owing to a surplus of fresh plant biomass-carbon(C)inputs.Highly heterogeneous sediment samples did not show any significant differences among sites(P>0.05).The lowest values of the ratio of absorbances at 465 and 665 nm(E4/E6)(1.78)and the Δ log K(0.15)coefficient(a measure of HS maturity degree)were obtained downstream of C ordoba City,for both riparian soil and sediment,indicating that HS were enriched by more condensed aromatic structures within highly degraded portions of the river.All samples exhibited similar IR spectra,implying overlapping recalcitrant-C structures at the functional group level,but with different absorbance intensity.Data from the current study constitute a baseline for understanding the chemical nature of HS from sediment and riparian soil along the Suquía River and can be used as a reference for future studies tracking OM compositional changes over time.Carolina Merlo Carolina Vázquez Ana Graciela Iriarte Carlos Matías Romero 2020International Journal of Sediment Research2020,35,3:3
