The study finds that increased physical activity may protect kidney function, as suggested by the modest yet significant associations observed in large-scale analyses using eGFRCysC measurements. However, we note several biases in the use of the Cox proportional hazards (CoxPH) model that the authors did not address.</p>\u0000<p>The established criteria may result in mixed censoring outcomes, that is, right-censoring and interval-censoring events [<span>2, 3</span>]. Events of kidney function diagnosed through medical records could result in interval-censoring if they occurred between follow-up visits, and right-censoring for diagnosed between the end of follow-up and the time of data analysis. The CoxPH model primarily handles right-censored data. In contrast, the accelerated failure time (AFT) model is often preferred for scenarios involving various types of censored data [<span>4</span>]. The AFT model can effectively handle left-censored, right-censored and interval-censored data by appropriately adjusting the likelihood function [<span>5</span>]. By using the ‘survival’ and ‘icenReg’ packages, mixed censored data can be fitted and analysed, and event times can be estimated [<span>6</span>].</p>\u0000<p>Moreover, the CoxPH model requires the proportional hazards assumption, meaning that covariate effects are constant over time [<span>7</span>]. If this assumption is violated, the model may not provide unbiased estimates of the coefficients, and the predictions may not be reliable. The authors should utilize Schoenfeld residuals or alternative methods to evaluate the proportional hazards assumption for the association between covariates and the risk of kidney function. Schoenfeld residuals are calculated as the differences between the observed and expected values of covariates at each failure time [<span>8</span>]. If the residuals exhibit a systematic change over time, it suggests that the effect of the covariate may be time-dependent. When the proportional hazards assumption does not hold, authors should use a stratified Cox model, a Cox model with time-varying effects, or an AFT model instead of the standard CoxPH model [<span>4, 9</span>].</p>\u0000<p>In conclusion, we believe that a re-evaluation considering the potential impact of censoring events and the proportional hazards assumption is necessary.

[<span>1</span>] regarding the impact of myosteatosis on post–liver transplantation (LT) outcome in males transplanted for hepatocellular carcinoma (HCC). The authors reported a relatively low prevalence of myosteatosis (27.8% in males) using a gender-based definition (i.e., muscle attenuation less than 37.5 HU at the third lumbar vertebra of cross-sectional CT image for men). However, in our recently published meta-analysis [<span>2</span>] including 10 studies with 3316 HCC patients, the overall pooled prevalence of myosteatosis was estimated as high as 50% (95% confidence interval [CI] 35%–65%) [<span>2</span>]. This discrepancy could be attributed to the fact that Lu et al. [<span>1</span>] included mainly chronic hepatitis B–associated HCC patients, although all patients were Asians. Indeed, our meta-analysis showed that the prevalence of myosteatosis is significantly lower in Asian HCC patients, compared to the non-Asian HCC patients (pooled prevalence 45% vs. 69%, respectively, <i>p</i> = 0.02), whereas viral-associated HCC patients have significantly less frequently myosteatosis, compared to those with fatty or alcoholic liver disease–associated HCC (pooled prevalence 49% vs. 65% vs. 86%, respectively, <i>p</i> &lt; 0.001). Interestingly, the authors [<span>1</span>] concluded that myosteatosis was not associated with post-LT outcome in females, although they did not provide which cutoff was used for definition of myosteatosis in this subgroup, although no clear explanation was given for this finding. In addition, they found no association between myosteatosis and hepatic encephalopathy although our meta-analysis [<span>3</span>] showed that cirrhotic patients with myosteatosis, compared to those without myosteatosis, have more frequently a previous history of hepatic encephalopathy (32% vs. 15%, <i>p</i> = 0.04) possibly related with the reduction of skeletal muscle capacity to remove ammonia. Finally, it would be interesting if the authors evaluated the impact of diabetes mellitus, which is an known factor associated with myosteatosis and poor prognosis after LT [<span>3, 4</span>], as well as if they compared the post-LT outcome of HCC patients with sarcopenia and myosteatosis/isolated myosteatosis versus those with isolated sarcopenia, as recent studies have shown that myosteatosis may be a more important factor, compared to sarcopenia, in the pre-LT setting of patients without HCC [<span>5</span>].</p>\u0000<p>Nevertheless, Lu et al. [<span>1</span>] confirmed the predictive role of myosteatosis in HCC patients not only in the pre-LT setting [<span>2</span>] but also in the post-LT outcome [<span>1</span>], indicating the importance of including assessment of myosteatosis in the process for LT evaluation. However, their results [<span>1</span>] need validation in non-Asian populations, in which the aetiology of liver disease is more frequently metabolic and alcohol-related HCC.</p>","PeriodicalId":186,"journal":{"name":"Journal of Cachexia, Sarcopenia and Muscle","volume":"8 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

[&lt;span&gt;1&lt;/span&gt;], which has used a variety of assessment approaches to innovatively investigate neuromuscular impairment in older human subjects. This study undoubtedly represents an important contribution to our understanding of the impact of age and sarcopenia on the human neuromuscular system, for which we wish to congratulate and thank the authors.&lt;/p&gt;\u0000&lt;p&gt;Although the authors have presented a lot of important new data, they state in their conclusions that ‘an altered innervation profile and NMJ instability are prominent features of the ageing of the neuromuscular system’. This is based on the claim that an increase in neural cell adhesion molecule-positive fibres is evidence of ‘increased muscle denervation’. We would like to raise caution against such a conclusion when based on the type of indirect data presented by Sarto et al. [&lt;span&gt;1&lt;/span&gt;].&lt;/p&gt;\u0000&lt;p&gt;The term ‘muscle denervation’ refers to a specific process whereby the nerve supply (innervation) of a muscle fibre, derived from a lower motor neuron input, is removed or lost. For this term to be accurate, therefore, it requires evidence showing that lower motor neuron inputs at the NMJ are removed or lost. We would politely suggest that an increase in neural cell adhesion molecule-positive fibres is not such evidence. Rather, anatomical and morphological studies of the NMJ are required to be able to draw such conclusions.&lt;/p&gt;\u0000&lt;p&gt;Sarto et al. [&lt;span&gt;1&lt;/span&gt;] point out in their paper that morphological evidence for NMJ disruption, and hence muscle denervation, is present in rodent models of ageing [&lt;span&gt;2&lt;/span&gt;] and use this to support their claims in humans. However, whilst technically challenging, comparable morphological studies of NMJs in young and old humans have been performed, showing that, in stark contrast to rodent models, NMJs remain structurally intact over the normal human lifespan [&lt;span&gt;3&lt;/span&gt;]. Such species-specific differences are perhaps not surprising given the inherent differences that exist in NMJ structure and stability between rodents and humans [&lt;span&gt;4, 5&lt;/span&gt;]. As such, the strongest &lt;i&gt;direct&lt;/i&gt; evidence available to date suggests that motor neuron inputs at the NMJ are not removed or lost with increasing age in humans. This in no way precludes the possibility that age- and/or sarcopenia-related changes, such as those reported by Sarto et al., [&lt;span&gt;1&lt;/span&gt;] are occurring in muscle that mimic denervation-induced changes. Rather, it questions the premise that such changes are occurring due to a loss of innervation resulting from structural breakdown of the NMJ.&lt;/p&gt;\u0000&lt;p&gt;The use of indirect measurements to draw conclusions about NMJ status and muscle denervation is not an issue solely restricted to Sarto et al.'s paper [&lt;span&gt;1&lt;/span&gt;], and we by no means wish to single out this important study in this regard (indeed, we strongly welc","PeriodicalId":186,"journal":{"name":"Journal of Cachexia, Sarcopenia and Muscle","volume":"44 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142451914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether tailored inpatient exercise prevents acute sarcopenia is unknown. This study aimed to examine the effect of a multicomponent exercise programme on muscle and physical function in hospitalized older adults. We hypothesized that participation in a brief tailored exercise regimen (i.e., 3-5 days) would attenuate muscle function and structure changes compared with usual hospital care alone.METHODSThis randomized clinical trial with blinded outcome assessment was conducted from May 2018 to April 2021 at Hospital Universitario de Navarra, Spain. Participants were 130 patients aged 75 years and older admitted to an acute care geriatric unit. Patients were randomized to a tailored 3- to 5-day exercise programme (n = 64) or usual hospital care (control, n = 66) consisting of physical therapy if needed. The coprimary endpoints were between-group differences in changes in short physical performance battery (SPPB) score and usual gait velocity from hospital admission to discharge. Secondary endpoints included changes in rectus femoris echo intensity, cross-sectional area, thickness and subcutaneous and intramuscular fat by ultrasound.RESULTSAmong 130 randomized patients (mean [SD] age, 87.7 [4.6] years; 57 [44%] women), the exercise group increased their mean SPPB score by 0.98 points (95% CI, 0.28-1.69 points) and gait velocity by 0.09 m/s (95% CI, 0.03-0.15 m/s) more than controls (both p < 0.01). No between-group differences were observed in any ultrasound muscle outcomes. There were no study-related adverse events.CONCLUSIONSThree to 5 days of tailored multicomponent exercise provided functional benefits but did not alter muscle or fat architecture compared with usual hospital care alone among vulnerable older patients.
