Impact of sarcopenia status of muscle-invasive bladder cancer patients on kidney function after neoadjuvant chemotherapy

BACKGROUND

Sarcopenia is suspected to influence the complication rates in patients undergoing radical cystectomy (RC). The aim of our study was to assess variations in sarcopenia in patients scheduled for neoadjuvant cisplatin-based chemotherapy (NAC) and RC for muscle invasive bladder cancer (MIBC) and to explore the impact of sarcopenia on complications linked to NAC or surgery.

METHODS

Between 2012 and 2017, 82 consecutive patients who underwent NAC and RC for cT2-T4 N0 MIBC were retrospectively selected. Using CT scan before and after NAC, Lumbar Skeletal Muscle Index (SMI) was assessed by two observers. We defined severe sarcopenia as SMI <50 cm²/m² for men and SMI <35 cm²/m² for women. We evaluated pre- and post-NAC cisplatin-based chemotherapy renal function and post-operative complication rates after cystectomy using the Clavien-Dindo classification. We explored risk factors of complications by logistic regression models.

RESULTS

According to the SMI, 47 patients (57.3%) were classified as sarcopenic and 35 patients (42.7%) non-sarcopenic. Patients' characteristics between sarcopenic and non-sarcopenic patients were not significantly different except for BMI (P<0.001). Among patients non-sarcopenic before NAC, nine (25.7%) became sarcopenic after NAC. In multivariate analysis, sarcopenia was an independent significant predictor of renal impairment after NAC (P=0.02). Moreover, sarcopenia and ASA score were independent significant predictors of postoperative early complications (P=0.01 and P=0.03, respectively).

CONCLUSIONS

We observed significant changes in sarcopenic status during NAC. Sarcopenia, estimated by the lumbar SMI measurement, was an independent predictor associated with the risk of renal impairment during NAC and early postoperative complications after RC.

Ophthalmologic findings in contact sport disciplines

BACKGROUND

The aim of the study was to investigate the prevalence and the incidence of ocular complications in contact sport disciplines in a large population of professional and amateur athletes over a period of 3 years.

METHODS

We performed a retrospective review of 694 medical records from athletes examinated from 2008 to 2011. The following data were collected during the routine visit for agonistic sports eligibility: medical history, age, weight, years of sport practice, approximate number of matches, head and eyes injuries during and beyond of the match and a through ocular history. All athletes underwent a detailed ophthalmological evaluation. The follow-up of each athlete was carried out during the following routine visit for agonistic sports eligibility.

RESULTS

Most common disorders observed were: peripheral retinal degeneration, blepharitis, conjunctival and corneal diseases with a prevalence of 7%, 4%, 7% and 4% respectively. It was observed a positive correlation between peripheral retinal degeneration and age in amateur male boxers. Moreover, we noticed an incidence of 6% of laser therapeutic treatments as a result of retinal holes or degenerations, during the follow-up.

CONCLUSIONS

Contact sport disciplines did not result in higher prevalence of severe ocular lesion. Both conjuntival diseases and peripheral retinal degenerations represented the ophthalmologic disorders with the higher prevalence in our sample. In particular, peripheral retinal degeneration is remarkable because of the increased risk of retinal detachment. Dyschromatopsie, even if quite rare, should be considered when analysing the reception of shots, since gloves in most cases are either red or blue.
