Inferior vena cava reconstruction in extended right hepatectomy

To the Editor : Barcelona Clinic Liver Cancer(BCLC) Stage C hepatocellular carcinoma(HCC) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced HCC who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant HCC in right liver lobe with inferior vena cava(IVC) invasion.

Treatment of Vulvovaginal Candidiasis with A Strategy Based on Phototherapy (M.A.C.^® Scar Acceleration Method)

引用

Modern Research in Inflammation 2024年第1期13卷 1-7页

作者： Marcus Vinicius de Mello Pinto karin Yuri Fernández Iturra Aline Ronis Sampaio María Elena Silva Álvarez Esteban Fortuny Celulare Institute Petrópolis Brazil Bienus Clinic Santiago Chile Fisiocare Curicó Chile Universidad Finis Terrae Santiago Chile

Candidiasis, also known as candidiasis vulvovaginitis, is an infection caused by different types of Candida fungi, the most frequent being Candida albicans. The present study reports an effective strategy, which opens new avenues for the treatment of this public health problem. The MAC® Methodology, conventional laser light-emitting (LLLT)/LED) methods are based on the biphasic response demonstrated many times in LLLT research and as with other forms of drugs, a “drug” (irradiation parameters) and a “dose” (irradiation times) and the “Arndt-Schulz Law” is often cited as a suitable model to describe the dose-dependent effects of LLLT. This method uses photopharmaceuticals, cell markers and the use of correct parameters for each case to induce the acceleration of tissue repair. The present study shows a case of a 32-year-old patient diagnosed with recurrent candidiasis 4 years ago. Eighteen sessions were performed (every other day) using a photoactivated component (Methylene blue 1% + Clotrimazole 1%) and LED phototherapy (red, blue and violet) with emission times of 60 - 260 seconds for each applicator, according to the dose recommendations of the scar acceleration method (MAC®). At the sixth treatment session there was a noticeable decrease in the itching sensation reported by the patient. In session 11 she reported feeling a great improvement, indicating that she no longer felt itching in any area after 18 sessions. The present case demonstrates new methodologies to treat common problems in the population that have a positive impact on the quality of life. This methodology has a promising future because it is non-invasive and requires a great biological transformation for inflammatory, fungal and viral control.

化疗引起的恶心呕吐(CINV)是众多抗癌药物治疗中常见的不良事件,不仅会对患者生活质量带来负面影响,还有可能影响化疗效果。目前,指南建议的止吐方案可以预防大部分癌症患者的CINV。但临床医师并不能始终遵循指南建议,患者也常常难以坚持医师处方的治疗。因此需要采取一些提高指南依从性的方法。奈妥匹坦帕洛诺司琼(NEPA)是首个也是唯一一个固定剂量复方止吐药,由奈妥匹坦(口服)/福奈妥匹坦(静脉给药)与帕洛诺司琼(PALO)组成。NEPA可以联合地塞米松组成三联止吐方案,这是用于高致吐性化疗(HEC)患者和部分中致吐性化疗(MEC)患者预防CINV的推荐方案。因此,NEPA止吐治疗操作简单便捷,可能有助于提高指南依从性。本综述对CINV进行了概括,评价了在临床试验和真实实践中积累的NEPA止吐效果及安全性方面的证据,同时也评价了在关键临床试验之外的环境下,即日常临床环境中使用NEPA进行止吐的初步证据。此外,本文还评述了化疗期间使用NEPA控制恶心症状和提高患者生活质量,这是癌症患者管理中面临的两个大挑战。

Electronic correlation in nearly free electron metals with beyond-DFT methods

作者： Subhasish Mandal Kristjan Haule karin M.Rabe David Vanderbilt Department of Physics and Astronomy West Virginia UniversityMorgantownWVUSA Department of Physics and Astronomy Rutgers UniversityPiscatawayNJUSA

For more than three decades,nearly free-electron elemental metals have been a topic of debate because the computed bandwidths are significantly wider in the local density approximation to density-functional theory(DFT)than indicated by angle-resolved photoemission(ARPES)***,we systematically investigate this using first principles calculations for alkali and alkaline-earth metals using DFT and various beyond-DFT methods such as meta-GGA,G0W0,hybrid functionals(YS-PBE0,B3LYP),and LDA+*** find that the static non-local exchange,as partly included in the hybrid functionals,significantly increase the bandwidths even compared to LDA,while the G0W0 bands are only slightly narrower than in *** agreement with the ARPES is best when the local approximation to the self-energy is used in the LDA+eDMFT *** infer that even moderately correlated systems with partially occupied s orbitals,which were assumed to approximate the uniform electron gas,are very well described in terms of short-range dynamical correlations that are only local to an atom.
