1Relative peripheral refraction across 4 meridians after orthokeratology and LASIK surgery显示文摘Background:To characterize the axial and off-axis refraction across four meridians of the retina in myopic eyes before and after Orthokeratology(OK)and LASIK surgery.Methods:Sixty right eyes with a spherical equivalent(M)between−0.75 to−5.25 D(cylinder<−1.00 D)underwent LASIK(n=26)or OK(n=34)to treat myopia.Axial and off-axis refraction were measured with an open-field autorefractometer before and after stabilized treatments.Off-axis measurements were obtained for the horizontal(35°nasal and temporal retina)and vertical(15°superior and inferior retina)meridians,and for two oblique directions(45–225°and 135–315°)up to 20°of eccentricity.The refractive profile was addressed as relative peripheral refractive error(RPRE).Results:OK and LASIK post-treatment results showed an increase of myopic relative refraction at several eccentric locations.At the four meridians evaluated,the M component of the pre-treatment RPRE values was not statistically different(p>0.05)from the post-treatment RPRE within 30°and 20°of the central visual field after LASIK and OK,respectively.These results demonstrated that the treatment zone warrants an optimal central field of vision.Conclusions:The present study gives an overview of RPRE after refractive corneal reshaping treatments(OK and LASIK)across vertical,horizontal and two oblique meridians together.This allows a 3D representation of RPRE at the retina and shows that the myopic shift induced by both treatments is more relevant in horizontal directions.António Queirós Ana Amorim-de-Sousa Daniela Lopes-Ferreira César Villa-Collar Ángel Ramón Gutiérrez JoséManuel González-Méijome 2018Eye and Vision2018,5,1:8
2Personalizing therapies for gastric cancer: Molecular mechanisms and novel targeted therapies显示文摘Globally,gastric cancer is the 4thmost frequently diagnosed cancer and the 2ndleading cause of death from cancer,with an estimated 990000 new cases and738000 deaths registered in 2008.In the advanced setting,standard chemotherapies protocols acquired an important role since last decades in prolong survival.Moreover,recent advances in molecular therapies provided a new interesting weapon to treat advanced gastric cancer through anti-human epidermal growth factor receptor 2(HER2)therapies.Trastuzumab,an anti-HER2 monoclonal antibody,was the first target drug in the metastatic setting that showed benefit in overall survival when in association with platinum-5-fluorouracil based chemotherapy.Further,HER2 overexpression analysis acquired a main role in predict response for trastuzumab in this field.Thus,we conducted a review that will discuss the main points concerning trastuzumab and HER2 in gastric cancer,providing a comprehensive overview of molecular mechanisms and novel trials involved.Michael Luis Ana Tavares Liliana S Carvalho Lúcio Lara-Santos António Araújo Ramon Andrade de Mello 2013World Journal of Gastroenterology2013,19,38:6
3Biometric and ICL-related risk factors associated to sub-optimal vaults in eyes implanted with implantable collamer lenses显示文摘Background:To identify biometric and implantable collamer lens(ICL)-related risk factors associated with suboptimal postoperative vault in eyes implanted with phakic ICL.Methods:This study reports a retrospective case series of the first operated eye in 360 patients implanted with myopic spherical or toric ICL.Preoperatively,white-to-white(WTW),central keratometry(Kc)and central corneal thickness(CCT)were measured using the Pentacam.Anterior-segment optical coherence tomography(AS-OCT,Visante)was applied preoperatively for measuring the horizontal anterior-chamber angle-to-angle distance(ATA),internal anterior chamber depth(ACD),crystalline lens rise(CLR),anterior-chamber angle(ACA)and postoperatively the vault.Eyes were divided into three vault groups:low(LVG:≤250μm),optimal(OVG:>250 and<1000μm)and high(HVG:≥1000μm).Multinomial logistic regression(MLR)was used to find the sub-optimal vault predictors.Results:MLR showed that CLR,ICL size minus the ATA(ICL size-ATA),age,ICL spherical equivalent(ICLSE)and ICL size as contributing factors for sub-optimal vaults(pseudo-R2=0.40).Increased CLR(OR:1.01,CI:1.00-1.01)and less myopic ICLSE(OR:1.22,CI:1.07-1.40)were risk factors for low vaults.Larger ICL size-ATA(OR:41.29,CI:10.57-161.22)and the 13.7mm ICL(OR:7.08,CI:3.16-15.89)were risk factors for high vaults,whereas less myopic ICLSE(OR:0.85,CI:0.76-0.95)and older age(OR:0.92,CI:0.88-0.98)were protective factors.Conclusion:High CLR and low ICLSE were the major risk factors in eyes presenting low vaults.In the opposite direction,ICL size-ATA was the major contributor for high vaults.This relationship was more critical in higher myopic ICLSE,younger eyes and when 13.7mm ICL were used.The findings show that factors influencing the vault have differentiated weight of influence depending on the type of vault(low,optimal or high).Santiago Cerpa Manito Angel Sánchez Trancón Oscar Torrado Sierra António Manuel Baptista Pedro Miguel Serra 2021Eye and Vision2021,8,1:5
4Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context.Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,2:3
5Anti-angiogenic therapies for metastatic colorectal cancer:Current and future perspectives显示文摘Colorectal cancer(CRC)is the fourth most commonly diagnosed cancer and the second leading cause of cancer death in both men and women in the United States,with about 142820 new cases and 50830 deaths expected in 2013.Metastatic disease(mCRC)remains a challenge for oncologists worldwide due to its potential comorbidities.Recently,chemotherapy regimens containing 5-fluorouracil,leucovorin,oxaliplatin and irinotecan combinations are a standard of care in the metastatic disease.Currently,biological therapies involving vascular endothelial growth factor and epidermal growth factor receptor pathways,such as bevacizumab and cetuximab,have emerged as good option for improving mCRC patient survival.Now,aflibercept plus standard chemotherapy has also been approved in second line regimen for mCRC patients.Our review will discuss novel biological drugs and their indications for mCRC patients and will bring future perspectives in this regard.Inês Marques António Araújo Ramon Andrade de Mello 2013World Journal of Gastroenterology2013,19,44:3
6Psychotropic drugs and liver disease:A critical review of pharmacokinetics and liver toxicity显示文摘The liver is the organ by which the majority of sub-stances are metabolized, including psychotropic drugs. There are several pharmacokinetic changes in end-stage liver disease that can interfere with the metabolization of psychotropic drugs. This fact is particularly true in drugs with extensive first--pass metabolism, highly protein bound drugs and drugs depending on phase I hepatic metabolic reactions. Psychopharmacological agents are also associated with a risk of hepatotoxicity. The evidence is insufficient for definite conclusions regarding the prevalence and severity of psychiatric drug-induced liver injury. High-risk psychotropics are not advised when there is pre-existing liver disease, and after starting a psychotropic agent in a patient with hepatic impairment, frequent liver function/lesion monitoring is advised. The authors carefully review the pharmacokinetic disturbances induced by end-stage liver disease and the potential of psychopharmacological agents for liver toxicity.Diogo Telles-Correia António Barbosa Helena Cortez-Pinto Carlos Campos Nuno B F Rocha Sérgio Machado 2017World Journal of Gastrointestinal Pharmacology and Therapeutics2017,8,1:3
7Effect of femtosecond laser-assisted lens surgery on the optic nerve head and the macula显示文摘AIM: To evaluate the effect of femtosecond laser-assisted lens surgery(FLALS;cataract surgery or refractive lens exchange) on the structure of the optic nerve head and the macula.METHODS: This prospective longitudinal study included healthy eyes undergoing FLALS. Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. Retinal nerve fiber layer(RNFL), Bruch’s membrane opening-minimum rim width(BMO-MRW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were evaluated.RESULTS: A total of 87 eyes of 46 patients were included in this study. Preoperative RNFL, BMO-MRW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative RNFL, BMO-MRW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative RNFL and BMO-MRW values were statistically significant(P<0.001). Regarding MT values, there were not statistically significant differences(P=0.26).CONCLUSION: Our study suggests that FLALS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of RNFL, BMO-MRW and MT 1 mo and 6 mo after surgery.Josefina Renones de Abajo Beatriz Estévez Jorge Jesús María González Martín Humberto Carreras Díaz Juan Francisco Loro Ferrer Alfonso Antón López 2019International Journal of Ophthalmology(English edition)2019,12,6:2
