RESUMO

Since ancient times human beings have been conceiving methods that could help reduce the accumulation of undesired fat tissue in their own bodies. Lipocryolysis has already been recognized as an therapy for localized fat reduction by means of a combination of regulated and controlled vacuum and heat extraction therapy. This study was designed to quantify the claimed reduction of local adiposities. For this purpose, 16 treatments were analysed. The data suggested that lipocryolysis is effective for localized reduction of adiposities and that the reduction obtained are measurable.

RESUMO

INTRODUCTION: Penile fracture (PF) is a urological emergency with low incidence, and evidence of its long-term outcomes is scarce. This study focuses on postoperative complications and long-term functional outcomes in patients with PF and surgical repair at our center. MATERIALS AND METHOD: Clinical records of patients undergoing urgent surgery for PF at a third level hospital between 2006 and 2020 were retrospectively reviewed. Functional outcomes were assessed with voluntary telephone interviews from June 2020 to February 2021. Lower urinary tract symptoms were screened by IPSS questionnaire, sexual function by EHS and IIEF-5 and morphological alterations by direct questions to patients. RESULTS: A total of 41 patients underwent surgery for PF. Eleven of them also had urethral injury (higher incidence if there was bilateral corpora cavernosa injury, 19.4% vs. 80%, p < 0.05). Only 1 patient presented a Clavien-Dindo type 3a complication due to wound dehiscence, 4 (13%) type 2 and 9 (29%) type 1. Twenty-four patients underwent long-term follow-up, of whom 20 (83.3%) presented normal sexual function. Twelve patients (50%) had a palpable nodule at the fracture site, 8 (33.3%) had new onset penile curvature and 1 patient with previous urethral injury presented urethral stricture. CONCLUSION: In cases of penile fracture, there is a higher incidence of urethral injury if both corpora cavernosa are affected. Long-term functional sequelae after surgical repair of a PF are rare.

RESUMO

INTRODUCTION: Currently, final diagnosis of prostate cancer (PCa) is based on histopathological analysis of needle biopsies, but this process often bears uncertainties due to small sample size, tumour focality and pathologist's subjective assessment. METHODS: Prostate cancer diagnostic signatures were generated by applying linear discriminant analysis to microarray and real-time RT-PCR (qRT-PCR) data from normal and tumoural prostate tissue samples. Additionally, after removal of biopsy tissues, material washed off from transrectal biopsy needles was used for molecular profiling and discriminant analysis. RESULTS: Linear discriminant analysis applied to microarray data for a set of 318 genes differentially expressed between non-tumoural and tumoural prostate samples produced 26 gene signatures, which classified the 84 samples used with 100% accuracy. To identify signatures potentially useful for the diagnosis of prostate biopsies, surplus material washed off from routine biopsy needles from 53 patients was used to generate qRT-PCR data for a subset of 11 genes. This analysis identified a six-gene signature that correctly assigned the biopsies as benign or tumoural in 92.6% of the cases, with 88.8% sensitivity and 96.1% specificity. CONCLUSION: Surplus material from prostate needle biopsies can be used for minimal-size gene signature analysis for sensitive and accurate discrimination between non-tumoural and tumoural prostates, without interference with current diagnostic procedures. This approach could be a useful adjunct to current procedures in PCa diagnosis.

RESUMO

INTRODUCTION: Collagenase Clostridium histolyticum (CCH) is the only approved treatment for conservative management of Peyronie's disease (PD) that has demonstrated efficacy and safety in clinical trials. However, as the standard treatment protocol is time and resource consuming, we are introducing a new CCH treatment protocol with a more cost-effective profile. Our goal is to evaluate its efficacy and safety. MATERIALS AND METHODS: We included patients with PD in stable phase, with curvatures of 30-90degrees. Ventral curvatures and complex deformities were excluded. The treatment protocol consists of a full dose of CCH injected along the PD plaque, forming two lines of four injections. Patients were educated in daily penile modeling activities. The need for a new treatment cycle, up to a maximum of 8 cycles or until the 30-degree curve was decreased, was reevaluated every 4weeks. Changes in curvature and number of cycles were recorded to evaluate the efficacy. Regarding safety evaluation, treatment-related adverse events (TRAEs) were recorded, including rupture of the corpora cavernosa, penile hematoma, hematuria, and local infection. RESULTS: Thirty-one patients were treated under the modified protocol. The mean initial curvature was of 49.84 (±15.83) degrees. Curvature improvement was recorded in 25 patients (80.6%), with a mean absolute reduction of 20.65 (±15.42) degrees and relative reduction of 44%. The mean curvature after treatment was 30.67 (±17.25) degrees. Most patients required one (19.4%) or two (54.8%) injections. No patient presented TRAEs. CONCLUSIONS: The results suggest that the modified CCH treatment protocol is effective and safe, but more studies should be carried out to optimize the current standard protocol.

RESUMO

BACKGROUND: B-lines have been associated with adverse clinical outcomes in patients with heart failure (HF) when found at hospital discharge or during outpatient visits. Whether lung ultrasound (LUS) assessed B-lines may predict in-hospital mortality in patients with acute HF is still undetermined. AIM: To evaluate the association between B-lines on admission and in-hospital mortality among patients admitted with acute HF. METHODS: Hand-held LUS was used to examine patients with acute HF. LUS was performed in eight chest zones with a pocket ultrasound device and analyzed offline. The association between B-lines and in-hospital mortality was assessed using Cox regression models. RESULTS: We included 62 patients with median age 56 years, 69.4% men, and median left ventricle ejection fraction 25%. The sum of B-lines ranged from 0 to 53 (median 6.5). An optimal receiver operating characteristic-determined cut-off of ≥19 B-lines demonstrated a sensitivity of 57% and a specificity of 86% (area under the curve 0.788) for in-hospital mortality. The incremental prognostic value of LUS when compared with lung crackles or peripheral edema by integrated discrimination improvement was 12.96% (95% CI: 7.0-18.8, P = 0.02). Patients with ≥19 B-lines had a 4-fold higher risk of in-hospital mortality (HR 4.38; 95% CI: 1.37-13.95, P < 0.01). CONCLUSION: In patients admitted with acute HF, point-of-care LUS measurements of pulmonary congestion (B-lines) are associated with in-hospital mortality.

RESUMO

AIM: To test the feasibility, efficacy and safety of a new two port laparoscopic technique for dialysis catheter placement. MATERIAL AND METHODS: From January 2006 to July 2009 51 patients underwent dialysis catheter placing using an original technique. All procedures were finished laparoscopically using two 12 mm-sized ports. Our technique bases on placing Oreopoulos-Zellerman catheter along a straight Guyon s guide with atraumatic tip, visually guaranting optimal placement. Catheter can be repositioned if desired by reentering the guide. Median follow-up was 25 months. RESULTS: Mean operating time was 32 minutes (range 15-55 minutes). One patient suffered an immediate postoperative catheter obstruction that required surgical repositioning. No other technical intra or early postoperative complications related to technique were reported. Mean time to discharge 1.02 +/- 2.2 days. Catheter outflow failure rate was 7.6%. Conversion to haemodialysis due to peritonitis 13%. Peritonitis per patient/year was 0.27. Catheter 6 mo, 1 year and 2 year survival rate was 94%, 87% and 72%. Catheter migration rate was 4%. There was no peritoneal dialysis liquid leakage. CONCLUSIONS: The two ports technique described is an easy and rapid procedure, with few complications and early discharge. Due to its reliability, offers good catheter function outcome.

RESUMO

OBJECTIVES: We aimed to explore the potential benefits of using smart glasses - wearable computer optical devices with touch-less command features - in the surgery room and in outpatient care settings in urology. MATERIALS AND METHODS: Between April and November 2015, 80 urologists were invited to use Google Glass in their daily surgical and clinical practice, and to share them with other urologists. Participants rated the usefulness of smart glasses on a 10-point scale, and provided insights on their potential benefits in a telephone interview. RESULTS: During the testing period, 240 urologists used smart glasses, and the 80 initially invited rated their usefulness. Mean scores for usefulness in the surgery room and in outpatient clinics were 7.4 and 5.4, respectively. The interview revealed that the applications of smart glasses considered most promising in surgery were live video streaming and static image playback, augmented reality, laparoscopic navigation, and digital checklist for safety verification. In outpatient settings, participants considered the glasses useful as a viewing platform for sharing test results, for browsing digital vademecum, and for checking medical records in emergency situations. CONCLUSIONS: Urologists engaged in our experience identified various uses of smart glasses with potential benefits for physician's daily practice, particularly in the urological surgery setting. Further quantitative studies are needed to exploit the actual possibilities of smart glasses and address the technical limitations for their safe use in clinical and surgical practice.

RESUMO

CONTEXT: The revolution of digital technologies constitutes a new setting for the patient-physician relationship and provides patients with a scenario of privacy and universal access to a vast amount of information. However, there is little information on how digital resources are used and what their advantages and disadvantages are. OBJECTIVES: To explore the scope of the scientific research on the use of digital technology related to men's sexual disorders and to analyze the primary sources of digital information related to this field. ACQUISITION OF EVIDENCE: Systematic searches of the scientific literature, websites (10 first results in each google search) and mobile applications (apps). The searches combined the keywords "web" and "app" with "erectile dysfunction", "premature ejaculation", "Peyronie", "male hypogonadism", and "infertility". Websites and apps were assessed for quality according to predefined indicators. SYNTHESIS OF EVIDENCE: The qualitative analysis of the scientific literature included 116 manuscripts; 47% were clinical studies based on online survey, 9% dealt with digital treatments, 11% with quality/safety of digital healthcare environment, 3% with digital activity, 21% with patient empowerment, and 9% with online drug selling. Of 50 websites assessed for quality, 29 (58%) scored 4 or 5 on a 5-point Likert scale. The app search yielded 40 apps; only 3 of them (8%) reported the identity of a health center or healthcare professional involved. CONCLUSIONS: Patients and healthcare professionals may benefit from digital resources related to men's sexual disorders; however, a strong commitment by the scientific and healthcare community is essential to increase the quality of these resources.

RESUMO

OBJECTIVE: To assess the outcomes of ureteral stent placement under local anesthesia for the management of multiple ureteral disorders. METHODS: Retrospective study of 45 consecutive ureteral stents placed under local anesthesia from January 2015 to July 2016. Inclusion criteria were hemodynamically stable patients with urinary obstruction, urinary fistula or for prophylactic ureteral localization during surgery. Five minutes before the procedure, 10ml of lidocaine gel and 50ml of lidocaine solution were instilled in the bladder. A 4.8Fr ureteral stent was placed using a 15.5Fr flexible cystoscope under fluoroscopic control. Characteristics of procedures and outcomes were analysed. RESULTS: A total of 45 procedures (33 placement, 12 replacements) were attempted in 37 patients, of which 40 (89%) were successful. There were 10 male (27%) and 27 female patients (73%) with a mean age of 58.6 years (±17.5). Main indications for stent placement were stones (37.8%), extrinsic ureteral compression (28.9%) and surgery ureteral localization (22.2%). The reasons for failing to complete a procedure were the inability to pass the guidewire/stent in 4 cases (8.8%) or to identify the ureteral orifice in 1 (2.2%). Postoperative complications occurred in 8 patients (17.8%) (7 Clavien I, 1 Clavien IIIa). No procedure was prematurely terminated due to pain. Statistical analysis did not find significant successful predictors. The outpatient setting provided a fourfold cost decrease. CONCLUSIONS: Ureteral stent placement can be safely and effectively performed under local anesthesia in the office cystoscopy room. This procedure could free operating room time, reduce costs and minimize side effects of general anesthesia.

RESUMO

The difficulty implicit in combining all the characteristics that an ideal patch to treat Peyronie's disease with a lengthening procedure should have, together with the challenges of comparing results from different series, means that the ideal patch has yet to be determined. Our objective with this review was to determine whether any given patch type is preferable to the others based on the evaluation of the results of published studies. A systematic search of the literature was conducted from PubMed until December 2016. Articles reporting basic research, animal research, reviews or meta-analyses and studies in children were eliminated. Series with patients undergoing some kind of other surgical intervention were only included if results were reported separately. Case reports and series of five patients were excluded. Five variables were selected to evaluate the results: number of patients, follow-up period, straightening rate, shortening rate and post-operative ED rate. For this purpose, 69 papers were included for review, and the outcomes of the use of autologous dermis, tunica vaginalis, dura mater, fascia, saphenous vein, tunica albuginea, buccal mucosa, porcine intestinal submucosa, pericardium, TachoSil® and synthetic materials were presented and analysed separately. The different series published are extremely variable and heterogeneous in terms of the number of patients included, patient selection, follow-up periods, and in the measurement and interpretation of the outcomes analysed. Given these facts, it is not possible to draw any definitive conclusion, homogeneous, prospective studies using validated tools are required to determine which the ideal graft is.

RESUMO

OBJECTIVE: To explore the potential relationship between erectile dysfunction (ED), low testosterone levels, and the Charlson Comorbidity Index (CCI). MATERIAL AND METHODS: Cross-sectional study on patients referred to the andrology unit in 7 Spanish centers. The ED was diagnosed and graded using the International Index of Erectile Function (IIEF-5) score. Total testosterone, the prevalence of each comorbidity, and the CCI were compared between patients with different grades of ED. Besides, the correlation between total testosterone and the CCI score, the influence of each comorbidity, and the ED severity on the CCI was assessed in a multiple linear regression. RESULTS: The study included 430 men with a mean age of 61 years. The mean CCI was 3.5, and mean total testosterone 15.2 nmol/L; 389 (91%) subjects had some grade of ED: 97 (23%) mild, 149 (35%) mild-to-moderate, 86 (20%) moderate, and 57 (13%) severe. The increase in ED severity was significantly associated with a decrease in total testosterone (P=.002), and an increase in the CCI score (P<.001). Testosterone levels were significantly lower in patients with obesity, diabetes, hypercholesterolemia, and hypertriglyceridemia (P<.05). However, only the prevalence of diabetes and hypertension was significantly associated with the severity of ED. The multivariate analysis including variables related to all assessed comorbidities, total testosterone levels, and the DE severity significantly predicted the CCI score (P<.001, R2=.426). The severity of ED significantly contributed to this model (P=.011), but total testosterone did not (P=.204). CONCLUSIONS: The CCI is significantly associated with the ED severity, but it shows a weak correlation with the testosterone levels.

RESUMO

OBJECTIVE: To analyze the relationship between the age--adjusted Charlson Comorbidity Index (aCCI) and pathological outcomes of transurethral resection of de novo bladder tumours (BT). MATERIAL AND METHODS: Data from 208 patients who underwent a transurethral resection (TUR) of a de novo BT between 2007 and 2008 were collected. We recorded the following variables: age, sex, tobacco consumption, comorbidities assessed according to the ICCa (score and mortality rate), disease stage, tumour grade and risk of recurrence and progression. The relationship between the preoperative variables and the final pathological characteristics was analyzed. The multivariate study was conducted with the significant variables (P<.05) from the univariate analysis. RESULTS: The mean age of the patients was 69.5 ± 12 years, and 77% were men. The mean ICCa was 6.4 ± 2.5. The final pathology results showed a Tx, T0, Ta, T1 and T ≥ 2 in 5.3, 6.7, 31.7, 26.9, and 28.8% of the cases, respectively. 33.3% of the tumours were low-grade and 66.7% were high-grade. 14.3% of the tumours were associated with carcinoma in situ. Among those non musculo-invasive bladder tumour (non-MIBT), 34.7% had a low risk of recurrence and progression, 18.1% had an intermediate risk and 47.2% had a high risk. The patients with a ICCa ≥ 5 had an increased number of MIBT (RR: 2.29; 1.1-4.8; P=.032), high-grade tumours (RR: 3.1; CI: 1.6-6; P=.001) and tumours with a high risk of recurrence and progression (RR: 2.9; CI: 1.4-5.9; P<.001). CONCLUSION: The ICCa is related to the pathological characteristics of de novo BT. Patients with greater comorbidity can present more aggressive tumours. The ICCa could therefore be useful in clinical practice for identifying patients with worse prognosis.

RESUMO

OBJECTIVE: To describe the temporal trends in surgical techniques for the management of renal masses at a single Spanish academic institution and identify factors associated with partial nephrectomy (PN) decision. MATERIALS AND METHODS: A total of 646 patients were treated by surgery for clinically localised renal masses from January 2004 to December 2012 at a tertiary referral center. Surgical techniques included open radical nephrectomy (RN), open PN, laparoscopic RN, and laparoscopic PN. Descriptive statistics were used to compare baseline characteristics and proportions of patients treated by different surgical techniques. Annual trends in the proportion of procedures performed were determined. Adjusted odds ratios (OR) and 95% confidence intervals were calculated to evaluate clinical variables predictive of PN. RESULTS: During the 9-year study period, the proportion of PN relative to RN increased from 21% to 55%. With regard to surgical approach, open procedures for both RN and PN decreased gradually in favor of minimally invasive approaches (83% in 2004 to 4% in 2011-2012). While median tumor size did not significantly change over the study period, laparoscopic PN became the most commonly performed kidney procedure in 2011-2012 (49% of all procedures). Clinical variables independently predictive of partial nephrectomy were ASA score, baseline renal function and tumor size (all P<.05). CONCLUSIONS: At our academic institution, temporal trends in the management of renal masses have established PN as the most common surgical option. Although PN was increasingly used over the study period, a parallel increase in minimally invasive approaches for RN and PN was seen.

RESUMO

OBJECTIVES: To analyze the predictors for bladder recurrence (BR) after nephroureterectomy (NU) for upper urinary tract tumors (UUTT), as well as its pathological characteristics, outcomes and impact on survival. MATERIAL AND METHODS: Retrospective study of 117 patients who underwent laparoscopic nephroureterectomy by UUTT between 2007-2012 at our center. The potential predictors for BR were analyzed using Cox regression; Kaplan-Meier curves were employed to study survival. RESULTS: The sample was composed of 85 men (73%) and 32 women (27%), with a mean age of 70 years. After a mean follow-up of 26 months, 23 patients presented BR (19.6%). In the multivariate analysis, sex (p=.003; HR [female], 3.8) and the location of the UUTT in the distal ureter (p=.002; HR, 4.8) were independent predictors for BR. The median time to BR was 8 months. Fifteen patients presented a nonmuscle-invasive BR (65.2%), and 8 presented a muscle-invasive BR (34.8%). All BRs, except for 2, appeared during the first 2 years. Five cases with nonmuscle-invasive BR presented a new BR. Six patients with muscle-invasive BR died before it could be determined whether cause of death was the BR or an UUTT relapse. The onset of BR showed no repercussion on the survival of patients with UUTT. CONCLUSIONS: Sex (female) and the location of the UUTT (distal ureter) are predictors for BR after NU. Patients with these characteristics might benefit from adjuvant intravesical treatment and closer monitoring. The onset for RV has no impact on the survival of patients with UUTT.

RESUMO

OBJECTIVES: To assess the feasibility and the safety of conservative surgery to treat spermatic cord leiomyosarcoma. METHODS: Patients undergoing inguinoscrotal exploration in 10 different Urological Centers with diagnosis of leiomyosarcoma were enrolled. Preoperative evaluation included physical examination, Scrotal US, Abdominal CT and Scrotal MRI in selected cases. Patients underwent organ sparing surgery or orchiectomy in case of intraoperative FSE was positive for a local infiltration. Data collected were: age, presence of infiltration, length of the lesion, number of lesions, definitive histological outcome, pre and postoperative testosterone level. Follow up was performed with abdomen CT scan and scrotal US. RESULTS: From January 2007 to December 2013, 23 patients (mean age: 64.7 yrs) were diagnosed with spermatic cord leiomyosarcoma. Each patients underwent scrotal US. 10 patients underwent radical orchiectomy and 13 patients underwent conservative surgery. Mean follow up was 36.5 months. 5 patients (21.7%) developed a recurrent disease, 18 patients (78.3%) had a negative follow up (mean time: 40.8 months). Statistical analysis reveals that there is a significant correlation between number of lesions, length of the lesions and recurrent disease. CONCLUSIONS: Spermatic cord leiomyosarcoma is a rare disease. Conservative surgical treatment of spermatic cord leiomyosarcoma is a feasible therapeutic option for small, single and not infiltrating lesion.

RESUMO

OBJECTIVES: To study the utility of neurovascular preservation for postoperative erection in radical cystectomy. MATERIALS AND METHODS: Retrospective analysis of 44 cystectomies performed at our center between January 2006-December 2009 in men <65 years. In 11 cases a neurovascular preservation was done. We analyzed age, BMI, indication for surgery, urinary diversion, use of i-PDE5 or alprostadil, and daytime and nighttime continence. Erection Hardness Score (EHS) was used to assess erectile function. RESULTS: Spontaneous postoperative erectile function in preservation group was 44,4% EHS 4, 33,3% EHS 3 and 22,3% EHS 1 (achieving EHS 3 or 4 with alprostadil). In the non preservation group, 4,5% achieved EHS 4 spontaneously. The other 95,5% had EHS 0 (4,5% achieved EHS 3 with tadalafil 20 mg and 9% with intracavernous injections). Variables age (P=.001) and nerve-sparing surgery (P<.001) were related to postoperative erectile function recovery. In the multivariate analysis, nerve-sparing surgery remained statisticaly significant. CONCLUSIONS: The functional results in preserving cystectomy are promising. The preservation should be considered in young patients without erectile dysfunction.

RESUMO

This study examines the rheological behavior of reconstituted spray-dried mucilage isolated from the cladodes of pitahaya (Hylocereus undatus), the effects of concentration and its relationship with physical properties were analyzed in reconstituted solutions. Drying process optimization was carried out through the surface response method, utilizing a factorial 2(3) design with three central points, in order to evaluate yield and rheological properties. The reconstituted mucilage exhibited non-Newtonian shear-thinning behavior, which adequately fit the Cross model (R(2)>0.95). This dynamic response suggests a random coil configuration. The steady-shear viscosity and dynamic response are suitably correlated through the Cox-Merz rule, confirming the mucilage's stability of flow. Analysis of the physical properties of the mucilage (Tg, DTP, and particle morphology) explains the shear-thinning behavior.

RESUMO

OBJECTIVE: There is controversial evidence regarding preoperative testosterone (T) levels related to poor prognosis factors after radical prostatectomy (RP). The aim of this manuscript is to determine the relationship between preoperative T levels and final pathologic report together to biochemical recurrence after RP. MATERIALS AND METHODS: We prospectively analysed 143 patients submitted to RP from February 2008 to June 2010 in our centre. Pretreatment T and sex hormone-binding globulin levels were determined as part of our clinical protocol. Free calculated (fT) and bioavailable (bioT) T were calculated using Vermeulen's formula. Low T levels were defined as 346 ng/dL or less. A comparative analysis with variables pTNM, positive margins, tumour burden, Gleason score, multifocality and biochemical recurrence (using both PSA>0.4 ng/dL and PSA>0.2 ng/dL as cut-off values) was performed, according to preoperative levels of T. RESULTS: Variables Gleason score, rate and number of positive margins, tumour burden, tumour multifocality, time to biochemical recurrence and pathological stage were not related to preoperative hormonal levels. Preoperative T<346 ng/dL was not found to be related to PSA recurrence (PSA>0,4 ng/dL log-rank, P=.512), although a trend was observed when PSA>0,2 ng/dL (log-rank, P=.097). CONCLUSION: Preoperative T levels were not related to final pathological report or to biochemical recurrence.

RESUMO

Testosterone deficiency syndrome (TDS) is a clinical and biochemical entity related to sexual and cardiovascular health. Hypertension, diabetes mellitus (DM), dyslipidemia and overweight are four clinical factors strongly related to cardiovascular illnesses. The aim of our study was to determine if the presence and number of cardiovascular risk factors was related to total testosterone levels and the presence of biochemical TDS. We retrospectively analyzed 384 patients referred to our center for prostate biopsy between September 2007 and December 2009. Variables age, height, weight, body mass index (BMI), tobacco use, alcohol intake, hypertension, DM, dyslipidemia (hypercholesterolemia/hypertriglyceridemia) and overweight (BMI>25) were recorded prospectively. Hormonal profile was determined as part of our clinical protocol. We used 231 and 346 ng dl(-1) as total testosterone cut-points (8-12 nmol l(-1)) for diagnosis of biochemical TDS, following ISA-ISSAM-EAU Guidelines. We analyzed the relationship between testosterone levels and the presence of hypertension, DM, dyslipidemia and overweight, and with the number of these cardiovascular risk factors. Mean age was 66 ± 8 years. Prevalence of TDS was 6.5% within the 231 ng ml(-1) cutoff point and 28.4% for the 346 ng dl(-1) cutoff point. Levels of testosterone were related to hypertension (P=0.007), dyslipidemia (P=0.013), overweight (P=0.036) and the number of cardiovascular risk factors (P=0.018). The prevalence of TDS in our population is comparable to data from international studies. Testosterone levels decrease as the number of cardiovascular risk factors rise.
