Correlation between malnutrition, body mass index and complications in patients with urinary bladder cancer who underwent radical cystectomy

Abstract

There was no relationship between malnutrition, defined by the NRS scale, and postoperative complications, and we did not find a significant relationship between the other tested variables. We observed only 1 significant relationship between the nutrition state, measured by BMI scale, and the degree in Clavien-Dindo scale. Body mass index under 18.5 and over 30 increased postoperative complications. Nowadays, the recommended scale is NRS 2002, which is based mostly on loss of weight. In our patients, qualitative malnutrition is more probable than quantitative malnutrition.

Optimizing Nutritional Status in Patients Undergoing Radical Cystectomy: A Systematic Scoping Review

“…Although additional screening tools such as the Nutrition Risk Screening (NRS-2002) tool and the Malnutrition Universal Screening Tool (MUST) have been validated in the surgical setting, their predictive value in the setting of bladder cancer is poorly established [39,40]. There is evidence that these tools may also be limited in the setting of cancer, as nutritional risk is a complex entity affected not only by biochemical and immunological factors but also by taste/smell alterations, nausea, and dysphagia [41].…”

The correlations between gut microbiota of Muslim Thai lactating women and their dietary intake and gut microbiota of breastfed infants

“…The main study had revealed that almost 50% of subjects had VA deficiency based on total VA liver reserve (Pinkaew et al, 2021), while the average body mass index (BMI) was 22.5±3.9 kg/m 2 (Azis, Pinkaew & Wichienchot, 2021). However, according to Swalarz et al (2018), BMI is not the best indicator of malnutrition, because malnutrition already occurs much earlier and there is no cut-off for lactating women. The subjects had low energy intake compared to the requirement for lactating women, mainly due to low socio-economic status with an average family income of USD500 per month to support around five people in a family (Azis et al, 2021).…”

Commentary on: “Underweight patients are an often under looked ‘at risk’ population after undergoing posterior cervical spine surgery”

“…So far, the vast majority of the scientific literature on the impact of BMI upon surgical outcomes after spine surgery has focused on the deleterious effects of obesity and morbid obesity [9] , [10] , [11] . A few studies in other specialties have suggested that underweight patients may display higher rates of unfavorable outcomes, especially after oncological surgeries [12 , 13] As one of the first well-conducted studies highlighting the impact of low BMI upon complications rates after spine surgery, we believe the results of this study are definitely worthy of attention, especially taking into account the extensive efforts in the recent literature toward developing measures to quantify frailty as well as to evaluate its impact upon surgical outcomes after spine surgery [14 , 15] .…”
