003). Six-and-twelve score" groups discriminated OS group 1, n=123, 32 months (95% CI 27.5-63.5); group 2, n=101, 24 months (95% CI 19.6-28.4) and group 3, n=1, 27 months (p=0.024). When comparing the three scores, the Six-and-twelve score" showed the best discrimination power C-index 0.603, Akaike's information criterion (AIC) 1.642, likelihood ratio test (LRT) 16.21.

The Six-and-twelve score" is a prognostic tool for patients with HCC treated with DEB-TACE. However, few patients were included in the third group (score >12) and no differences were observed with BCLC, therefore its applicability is limited.

A high clinical suspicion supported by imaging tests is required. Surgical debridement should not be delayed in order to avoid total replacement of the liver parenchyma.

Intestinal lymphangiectasia is an unusual cause of protein-losing enteropathy due to either congenital malformation or the obstruction of the intestinal lymphatics. However, few reports have investigated the use of video capsule endoscopy in children with intestinal lymphangiectasia. This study was performed to evaluate the diagnostic value of video capsule endoscopy for paediatric intestinal lymphangiectasia.

In this retrospective study, we included all patients who underwent video capsule endoscopy between January 2014 and July 2020. Clinical information and video capsule endoscopy data were analysed.

Twelve children, 7 males and 5 females, with an age of disease onset of 4.5 (range 3.2-9.3) years, and a disease duration of 12.0 (range 1.3-30.0) months were enrolled. The most common symptoms were hypoproteinaemia (10, 83.3%), diarrhoea (7, 58.3%), oedema (6, 50.0%), and abdominal pain (3, 25.0%). Eight patients had low lymphocyte counts, whereas 10 had reduced serum albumin levels (23.2±5.8 g/L). Video capsule endoscopy revealed an overall white snowy appearance due to the presence of whitish, swollen villi in all patients. Regarding the macroscopic lesions of lymphangiectasia, 7 cases involved the entire small bowel from the duodenum to the ileocecal valve, while 5 cases involved part of the small bowel. All patients were treated with medium-chain triglyceride diets, and albumin infusions were administered for 10 patients; sirolimus treatment was administered to 3 patients. At the last follow-up, 5 patients still had hypoalbuminemia, and one patient had died of intestinal lymphoma.

Video capsule endoscopy is useful for the diagnosis of intestinal lymphangiectasia and should be applied as a valuable and less invasive examination to confirm or establish a diagnosis.

We recently discovered that visible-light-induced SNC intermediates can be trapped by fluorinated ketones via 1,2-carbonyl addition to afford benzoin-type products. This discovery represents a rare example of nucleophilic carbenes reacting with ketones and delivers an efficient, user-friendly, and scalable process for accessing fluorinated tertiary alcohol derivatives driven only by light circumventing the use of exogenous catalysts or additives.Proton exchange membrane water electrolyzer can sustainably and environmentally friendly produce hydrogen. However, it is hindered by the lack of high-performance anode catalysts for oxygen evolution reaction (OER) in acid electrolyte. Herein, IrCuNi deeply concave nanocubes (IrCuNi DCNCs) are successfully synthesized from the selective etching of the facet of cubic nanoparticles, and they significantly boost the OER. The obtained IrCuNi DCNCs show high activity toward OER in the acidic electrolyte, which only requires an overpotential of 273 mV to achieve the OER current density of 10 mA cm-2 at a low Ir loading of 6.0 μgIr cm-2. The precious metal based mass activity is 6.6 A mgIr-1 at 1.53 V, which is 19 times as high as that of pristine Ir. It demonstrates that the outstanding catalytic performance is beneficial from the well-defined multimetal concave nanostructures, which may shed light on the fabrication of efficient water electrolyzers.A benzoic acid-promoted C2-H borylation of indoles with pinacolborane to afford C2-borylated indoles is developed. Preliminary mechanistic studies indicate BH3-related borane species formed via the decomposition of pinacolborane to be the probable catalyst. This transformation provides a prompt route toward the synthesis of diverse C2-functionalized indoles.Self-assembly of small amphiphilic molecules in water can lead to nanostructures of varying geometries with pristine internal molecular organization. click here Here we introduce a photoswitchable aramid amphiphile (AA), designed to exhibit extensive hydrogen bonding and robust mechanical properties upon self-assembly, while containing a vinylnitrile group for photoinduced cis-trans isomerization. We demonstrate spontaneous self-assembly of the vinylnitrile-containing AA in water to form nanoribbons. Upon UV irradiation, trans-to-cis isomerizations occur concomitantly with a morphological transition from nanoribbons to nanotubes. The nanotube structure persists in water for over six months, stabilized by strong and collective intermolecular interactions. We demonstrate that the nanoribbon-to-nanotube transition is reversible upon heating and that switching between states can be achieved repeatedly. Finally, we use electron microscopy to capture the transition and propose mechanisms for nanoribbon-to-nanotube rearrangement and vice versa. The stability and switchability of photoresponsive AA nanostructures make them viable for a range of future applications.A sequential enantioselective conjugate addition/hydroalkoxylation between in situ generated ortho-quinomethanes and ynones by combining bifunctional squaramide and DBU catalysis has been developed. A variety of eight-membered cyclic ethers with two contiguous tertiary stereocenters were obtained in high yields with excellent stereoselectivities. This reaction not only provides a new strategy for constructing enantioenriched eight-membered cyclic ethers but also demonstrates the practicability of ynones as C4-syntons for the synthesis of chiral medium-membered rings.
