In this editorial I comment on the article by Ahmed et al published in a recent issue of the World J Orthop 2023;14:*** is well known that patients who have undergone a liver transplant(LT)may need to have a total hip arthroplasty(THA)or total knee arthroplasty(TKA)*** et al stated that the mortality rate in these patients was similar to the one of the general ***,there are three articles previously published that found higher mortality in LT patients who experienced THA/TKA than in the general population(individuals without LT).Therefore,in this Editorial I would like to point out that there is controversy in the literature regarding whether LT patients undergoing THA/TKA have higher mortality than the general ***,future research should attempt to resolve this controversy.

Nitrosamine and related food intake and gastric and oesophageal cancer risk: A systematic review of the epidemiological evidence

引用

World Journal of Gastroenterology 2006年第27期12卷 4296-4303页

作者： Paula Jakszyn carlos Alberto gonzález Unit of Nutrition Environment and CancerDepartment of Epidemiology and Cancer Registry. Institut Català d' Oncologia(ICO-IDIBELL)L'Hospitalet de Llobregat (08907)BarcelonaSpain

AIM： To study the association between nitrite and nitrosamine intake and gastric cancer （GC）, between meat and processed meat intake, GC and oesophageal cancer （OC）, and between preserved fish, vegetable and smoked food intake and GC. METHODS： In this article we reviewed all the published cohort and case-control studies from 1985-2005, and analyzed the relationship between nitrosamine and nitrite intake and the most important related food intake （meat and processed meat, preserved vegetables and fish, smoked foods and beer drinking） and GC or OC risk. Sixty-one studies, 11 cohorts and 50 case-control studies were included. RESULTS： Evidence from case-control studies supported an association between nitrite and nitrosamine intake with GC but evidence was insufficient in relation to OC. A high proportion of case-control studies found a positive association with meat intake for both tumours （11 of 16 studies on GC and 11 of 18 studies on OC）. A relatively large number of case-control studies showed quite consistent results supporting a positive association between processed meat intake and GC and OC risk （10 of 14 studies on GC and 8 of 9 studies on OC）. Almost all the case-control studies found a positive and significant association between preserved fish, vegetable and smoked food intake and GC. The evidence regarding OC was more limited. Overall the evidence from cohort studies was insufficient or more inconsistent than that from case-control studies.CONCLUSION： The available evidence supports a positive association between nitrite and nitrosamine intake and GC, between meat and processed meat intake and GC and OC, and between preserved fish, vegetable and smoked food intake and GC, but is not conclusive.

New insights into Wnt signaling alterations in amyotrophic lateral sclerosis: a potential therapeutic target?

引用

Neural Regeneration Research 2020年第9期15卷 1580-1589页

作者： carlos gonzález-Fernández Pau gonzález Francisco Javier Rodríguez Laboratory of Molecular Neurology Hospital Nacional de Parapléjicos (HNP)

Amyotrophic lateral sclerosis is a fatal neurodegenerative disorder characterized by upper and lower motor neuron degeneration, which leads to progressive paralysis of skeletal muscles and, ultimately, respiratory failure between 2–5 years after symptom onset. Unfortunately, currently accepted treatments for amyotrophic lateral sclerosis are extremely scarce and only provide modest benefit. As a consequence, a great effort is being done by the scientific community in order to achieve a better understanding of the different molecular and cellular processes that influence the progression and/or outcome of this neuropathological condition and, therefore, unravel new potential targets for therapeutic intervention. Interestingly, a growing number of experimental evidences have recently shown that, besides its well-known physiological roles in the developing and adult central nervous system, the Wnt family of proteins is involved in different neuropathologica conditions, including amyotrophic lateral sclerosis. These proteins are able to modulate, at least, three different signaling pathways, usually known as canonical(β-catenin dependent) and non-canonical(β-catenin independent) signaling pathways. In the present review, we aim to provide a general overview of the current knowledge that supports the relationship between the Wnt family of proteins and its associated signaling pathways and amyotrophic lateral sclerosis pathology, as well as their possible mechanisms of action. Altogether, the currently available knowledge suggests that Wnt signaling modulation might be a promising therapeutic approach to ameliorate the histopathological and functional deficits associated to amyotrophic lateral sclerosis, and thus improve the progression and outcome of this neuropathology.
