RESUMO
Robotic surgery with Da Vinci has revolutionized the treatment of several diseases, including prostate cancer; nevertheless, costs remain the major drawback. Recently, new robotic platforms entered the market aiming to reduce costs and improve the access to robotic surgery. The aim of the study is to compare direct cost for initial hospital stay of radical prostatectomy performed with two different robotic systems, the Da Vinci and the new Hugo RAS system. This is a projection study that applies cost of robotic surgery, derived from a local tender, to the clinical course of robotic radical prostatectomy (RALP) performed with Da Vinci and Hugo RAS. The study was performed in a public referral center for robotic surgery equipped with both systems. The cost of robotic surgery from a local tender were considered and included rent, annual maintenance, and a per-procedure fee covering the setup of four robotic instruments. Those costs were applied to patients who underwent RALP with both systems since November 2022. The primary endpoint is to evaluate direct costs of initial hospital stay for Da Vinci and Hugo RAS, by considering equipment costs (as derived from the tender), and costs of theater and of hospitalization. The direct per-procedure cost is 2,246.31 for a Da Vinci procedure and 1995 for a Hugo RALP. In the local setting, Hugo RAS provides 11% of cost saving for RALP. By applying this per-procedure cost to our clinical data, the expenditure for the entire index hospitalization is 6.7755,1 for Da Vinci and 6.637,15 for Hugo RALP. The new Hugo RAS system is willing to reduce direct expenditures of robotic surgery for RALP; furthermore, it provides similar peri-operative outcomes compared to the Da Vinci. However, other drivers of costs should be taken into account, such as the duration of OR use-that is more than just console time and may depend on the facility's background and organization. Further variations in direct costs of robotic systems are related to caseload, local agreements and negotiations. Thus, cost comparison of new robotic platform still remains an ongoing issue.

This study evaluates the difference of robot-assisted radical prostatectomy (RARP) costs in patients with similar preoperative characteristics operated on using the da Vinci® SP and Xi robotic platforms. We performed a retrospective analysis on 71 consecutive patients with prostate cancer who underwent RARP with the SP robot between June 2019 and April 2020. Propensity score (PS) matching was performed and 71 patients were selected from a cohort of 875 who underwent RARP with the Xi robot in the same period. We divided the total expense per surgery into the cost of disposable materials, robotic instruments (initial purchasing cost divided by the number of "lives"), and operative room costs. Only variable costs are included in this study, as fixed costs do not vary between procedures and are the same for both cohorts. Fixed costs include anesthesia, pathology, surgeon, and hospitalization fees. The median total cost for SP-RARP was $5586 ($5360-$5982) USD and $4875 ($4661-$5093) USD with the XI for a median cost difference of $707 ($584-$832) (P < 0.001). The median cost of disposables for the SP was $1877 ($1588-$2193) USD and for the Xi $1527 ($1407-$1781) USD, P < 0.001. Non-disposable instruments cost per case (fixed cost) was $1610 and $1270 USD for the SP and Xi, respectively. The cost of radical prostatectomy in the SP cohort is higher than the Xi cohort. The greater price was primarily due to the increased cost of instruments and disposable materials. In our experience, the lack of GelPOINT and space maker is also crucial factors to decrease the SP total cost.

BACKGROUND: Down syndrome (DS) shows neuropathology similar to Alzheimer disease, which presents olfactory impairment. Previous work showed olfactory impairment in DS, but a comprehensive evaluation of olfactory function in DS is lacking. METHODS: We investigated a large number (n = 56; M = 31, F = 25) DS participants (age range18-57y) using the "Sniffin' Sticks" Extended test. This comprises three subtests (threshold, discrimination, and identification) yielding a global score (TDI) defining normosmia, hyposmia, and functional anosmia. To the best of our knowledge, this is the second largest group of DS people investigated for olfactory function ever. Age- and sex matched euploid individuals (n = 53) were the control. RESULTS: In DS, TDI was lower (16.7±5.13 vs. 35.4±3.74; P<0.001), with DS people performing worse in any subtests (P<0.001 for all); 27 DS participants showed functional anosmia (i.e., TDI<16). In DS, age was weakly and negatively correlated with TDI (r = -0.28, P = 0.036) and identification (r = -0.34, P = 0.012). When participants were stratified in young adults (18-29y) and older adults (30-61y), a significant effect of age was found for identification in both DS (young adults, 8.3±2.58; older adults, 6.9±2.99; P = 0.031) and control (young-adult, 14.3±1.18, older adult, 13.0±1.54; P = 0.016). CONCLUSION: Olfactory function is overall severely impaired in DS people and may be globally impaired at relatively young age, despite of reportedly normal smell. However, specificity of this olfactory profile to DS should be considered with some caution because cognition was not evaluated in all DS participants and comparison with a control group of non-DS individuals having cognitive disabilities was lacking. Further study is required to longitudinally assess olfactory dysfunction in DS and to correlate it with brain pathology.

The recent dramatic increase in breast cancer incidence across China with progressive urbanization and economic development has signaled the urgent need for molecular and clinical detailing of breast cancer in the Chinese population. Our analyses of a unique transethnic collection of breast cancer frozen specimens from Shanghai Fudan Cancer Center (Chinese Han) profiled simultaneously with an analogous Caucasian Italian series revealed consistent transcriptomic data lacking in batch effects. The prevalence of Luminal A subtype was significantly lower in Chinese series, impacting the overall prevalence of estrogen receptor (ER)-positive disease in a large cohort of Chinese/Caucasian patients. Unsupervised and supervised comparison of gene and microRNA (miRNA) profiles of Chinese and Caucasian samples revealed extensive similarity in the comprehensive taxonomy of transcriptional elements regulating breast cancer biology. Partition of gene expression data using gene lists relevant to breast cancer as "intrinsic" and "extracellular matrix" genes identified Chinese and Caucasian subgroups with equivalent global gene and miRNA profiles. These findings indicate that in the Chinese and Caucasian groups, breast neoplasia and the surrounding stromal characteristics undergo the same differentiation and molecular processes. Transcriptional similarity across transethnic cohorts may simplify translational medicine approaches and clinical management of breast cancer patients worldwide.

Bronchial asthma is a costly disease: while the role of pharmaceutical strategies was greatly emphasised in order to alleviate its economic burden, the aetiological approach to asthma has received much less attention from this point of view. The impact of gastro-oesophageal reflux (GER)-related asthma was assessed in comparison to atopic asthma in 262 matched patients, and the corresponding direct and indirect annual costs calculated. All subjects were screened by means of a 95-item self-questionnaire. The overall resource utilisation was calculated for the last 12 months. Drug-induced annual costs were euro 290.4 (interquartile range-iqr 32.8) in atopic and euro 438.4 (iqr 27.8) in GER-related asthma (p<0.001); expenditure for medical consultations and diagnostics were euro 166.1 (iqr 14.8) vs. euro 71.6 (iqr 11.0) (p<0.001), and euro 338.4 (20.0) vs. 186.9 (iqr 26.5) (p<0.001), respectively. Direct costs due to hospital admissions and indirect costs due to absenteeism were also higher in GER-related asthmatics: 2.201.7+/-90.0 vs. euro 567.1+/-11.0 (p<0.001), and euro 748.7+/-94.7 vs. euro 103.6+/-33.9 (p<0.001), respectively. The total annual cost per patient was euro 1246.7 (iqr 1979.6) in atopic and euro 3967.1 (iqr 3751.5) in GER-related asthma, p<0.001. In conclusion, GER-induced asthma has a more relevant economic impact on healthcare resources than atopic asthma. Although further studies are needed, present data tend to demonstrate that when facing difficult asthma (GER-related asthma in this case), the aetiological assessment of the disease plays a critical role in optimising the approach to patients' needs.
