Abstract
This research aims to develop a diagnostic tool that can quickly and accurately detect prostate cancer using electronic nose technology and a neural network trained on a dataset of urine samples from patients diagnosed with both prostate cancer and benign prostatic hyperplasia, which incorporates a unique data redundancy method. By analyzing signals from these samples, we were able to significantly reduce the number of unnecessary biopsies and improve the classification method, resulting in a recall rate of 91% for detecting prostate cancer. The goal is to make this technology widely available for use in primary care centers, to allow for rapid and non-invasive diagnoses.

Abstract
CONTEXT Despite current standard of care, many patients at high risk of cardiovascular disease (CVD) still have elevated low-density lipoprotein cholesterol (LDL-C) levels. Alirocumab is a fully human monoclonal antibody inhibitor of proprotein convertase subtilisin/kexin type 9. OBJECTIVE The objective of the study was to compare the LDL-C-lowering efficacy of adding alirocumab vs other common lipid-lowering strategies. DESIGN, PATIENTS, AND INTERVENTIONS Patients (n = 355) with very high CVD risk and LDL-C levels of 70 mg/dL or greater or high CVD risk and LDL-C of 100 mg/dL or greater on baseline atorvastatin 20 or 40 mg were randomized to one of the following: 1) add-on alirocumab 75 mg every 2 weeks (Q2W) sc; 2) add-on ezetimibe 10 mg/d; 3) double atorvastatin dose; or 4) for atorvastatin 40 mg regimen only, switch to rosuvastatin 40 mg. For patients not achieving protocol-defined LDL-C goals, the alirocumab dose was increased (blinded) at week 12 to 150 mg Q2W. MAIN OUTCOME MEASURE The primary end point was percentage change in calculated LDL-C from baseline to 24 weeks (intent to treat). RESULTS Among atorvastatin 20 and 40 mg regimens, respectively, add-on alirocumab reduced LDL-C levels by 44.1% and 54.0% (P < .001 vs all comparators); add-on ezetimibe, 20.5% and 22.6%; doubling of atorvastatin dose, 5.0% and 4.8%; and switching atorvastatin 40 mg to rosuvastatin 40 mg, 21.4%. Most alirocumab-treated patients (87.2% and 84.6%) achieved their LDL-C goals. Most alirocumab-treated patients (86%) maintained their 75-mg Q2W regimen. Treatment-emergent adverse events occurred in 65.4% of alirocumab patients vs 64.4% ezetimibe and 63.8% double atorvastatin/switch to rosuvastatin (data were pooled). CONCLUSIONS Adding alirocumab to atorvastatin provided significantly greater LDL-C reductions vs adding ezetimibe, doubling atorvastatin dose, or switching to rosuvastatin and enabled greater LDL-C goal achievement.

Abstract
OBJECTIVE The 2007 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines recommend that community-acquired pneumonia (CAP) patients admitted to hospital wards initially receive respiratory fluoroquinolone monotherapy or beta-lactam plus macrolide combination therapy. There is little evidence as to which regimen is preferred, or if differences in medical resource utilization exist between therapies. Thus, the authors compared length of hospital stay (LOS) and length of intravenous antibiotic therapy (LOIV) for patients who received initial levofloxacin 750 mg daily versus ceftriaxone 1000 mg plus azithromycin 500 mg daily ('combination therapy'). RESEARCH DESIGN AND METHODS Adult hospital CAP cases from January 2005 to December 2007 were identified by principal discharge diagnosis code. Patients with a chest infiltrate and medical notes indicative of CAP were included. Direct intensive care unit admits and healthcare-associated cases were excluded. A propensity score technique was used to balance characteristics associated with initial antimicrobial therapy using multivariable regression to derive the scores. Propensity score categories, defined as propensity score quintiles, rather than propensity scores themselves, were used in the least squares regression model to assess the impact of LOS and LOIV. RESULTS A total of 495 patients from six hospitals met study criteria. Of these, 313 (63%) received levofloxacin and 182 (37%) received combination therapy. Groups were similar with respect to age, sex, most comorbidities, presenting signs and symptoms, and Pneumonia Severity Index (PSI) risk class. Patients on combination therapy were more likely to have heart failure and receive pre-admission antibiotics. Adjusted least squares mean (+/-SE) LOS and LOIV were shorter with levofloxacin versus combination therapy: LOS, 4.6 +/- 0.17 vs. 5.4 +/- 0.22 days, p < 0.01; and LOIV, 3.6 +/- 0.17 vs. 4.8 +/- 0.21 days, p < 0.01. Results for PSI risk class III or IV patients were: LOS, 5.0 +/- 0.30 vs. 5.9 +/- 0.37 days, p = 0.07; and LOIV, 3.7 +/- 0.33 vs. 5.2 +/- 0.39 days, p < 0.01. Due to the retrospective study design, limited sample size, and scope (single health-network), the authors encourage replication of this study in other data sources. CONCLUSIONS Given the LOS and LOIV reductions of 0.8 and 1.2 days, respectively, utilization of levofloxacin 750 mg daily for CAP patients admitted to the medical floor has the potential to result in substantial cost savings for US hospitals.

Abstract
PURPOSE Organ preservation has been investigated in patients (p) with infiltrating transitional cell carcinoma (TCC) of the bladder over the past decade as an alternative to radical cystectomy. This is a trimodal schedule study, including transurethral resection of bladder tumor (TURB), neoadjuvant chemotherapy and concomitant radiochemotherapy (RTC). PATIENTS AND METHODS From April 1996 until August 2005, 29 evaluable patients (p) with T2-T3NXM0 bladder cancer were enrolled. After a transurethral resection of bladder tumor (TURB), we administered 2 cycles of induction chemotherapy with CMV (15 p) or Gemcitabine-Cisplatin (14 p) followed by radiotherapy 45 Gy 1.8 Gy/fraction and two cycles of concomitant cisplatin 70 mg/m(2). 2-3 weeks later, a cystoscopy with tumor-site biopsy was performed. If complete histological response, p were treated with consolidation radiotherapy until 64.8 Gy. For p with residual or recurrent tumor, cystectomy was performed. RESULTS We included 28 men and 1 women (median age 63, range 39-72 years) with PS (ECOG) 0-1. The stage was: 21 p T2; 6 p T3a; and 2 p T3b. Toxicity was higher in CMV compared with Gem- Cis: grade (3/4) neutropenia 4/15 (26%) vs 1/14 (7%); febrile neutropenia 3/15 (20%) vs 1/14 (7%); grade (3/4) trombocytopenia 2/15 (13%) vs 1/14 (7%). Toxicities with concomitant RCT were low-moderate: urocystitis (26%) and enteritis (18%). RESPONSE microscopically complete TURB was obtained in 20 p (69%), but not in 9 p (31%) (7 microscopic, and 2 macroscopic residual tumor). We found a complete histologic response after induction RCT in 25 p (86%). After a median follow-up of 69.4 months (m) (range: 8-97.7), there were 8 deaths, with a overall survival of 72%. Furthermore 14 of 29 p (48%) were alive with intact bladder, and median survival time with intact bladder was 63.6 m (50.1-77.2); were predictive of best outcome T2 stage vs T3 (p < 0.0001), and complete histologic resection in initial TURB vs residual tumor (p = 0.0004). CONCLUSIONS Combined treatment provide high response rates and can be offered as an alternative option to radical cystectomy in selected patients with TCC. Patients with T2 stage and complete histologic resection in initial TURB had the best outcome.

Abstract
Alterations in the antioxidative system have been observed during total parenteral nutrition (TPN). Light exposure or changes in the composition of TPN formulas may affect this system. Bacterial translocation (BT) is frequent under TPN and may be related to oxidative status. The aim of this study was to determine the adverse effects of standard and glutamine-enriched TPN, with or without light exposure, on oxidative status (liver and kidney-reduced glutathione, GSH) and its relationship to BT. Thirty-three adult Wistar rats underwent central-venous cannulation and were randomly assigned to one of four groups receiving different TPN regimes for 10 days. The TPN group (n = 10) had standard TPN, the TPN(-) group (n = 8) standard TPN without light exposure, the GTPN group (n = 8) glutamine-enriched TPN, and the GTPN(-) group (n = 7) glutamine-enriched TPN without light exposure. A sham group (n = 16) receiving chow and water ad libitum and saline i.v. served as controls. At the end of the experiment, GSH was determined in liver and kidney tissue. Mesenteric lymph nodes and peripheral and portal blood samples were cultured for BT. Compared to sham rats, TPN groups had statistically significant lower GSH levels, but there were no differences between standard or glutamine-enriched groups or light-exposure groups. Sham animals had 12% BT. Significantly higher BT (P < 0.05) occurred in TPN rats: 70% in the TPN group, 88% in the TPN(-) group, 86% in GTPN (-) animals, and only 50% in the GTPN group (P = 0.06 vs TPN group). In conclusion, (1) TPN reduces antioxidant capacity; (2) glutamine supplementation or light protection does not improve tissue antioxidant capacity under TPN; (3) the absence of light exposure does not improve TPN-related BT; and (4) glutamine supplementation tends to reduce BT only in the presence of light.

Abstract
An NAD-dependent D-2-hydroxyacid dehydrogenase (EC 1.1.1.) was isolated and characterized from the halophilic Archaeon Haloferax mediterranei. The enzyme is a dimer with a molecular mass of 101.4 +/- 3.3 kDa. It is strictly NAD-dependent and exhibits its highest activity in 4 M NaCl. The enzyme is characterized by a broad substrate specificity 2-ketoisocaproate and 2-ketobutyrate being the substrates with the higher Vmax/Km. When pyruvate and 2-ketobutyrate were the substrates the optimal pH was acidic (pH 5) meanwhile for 2-ketoisocaproate maximum activity was achieved at basic pH between 7.5 and 8.5. The optimum temperature was 52 degrees C and at 65 degrees C there was a pronounced activity decrease. This new enzyme can be used for the production of D-2-hydroxycarboxylic acid.

Abstract
A case of a patient affected with intestinal obstruction of 4 days of evolution is presented. The diagnosis of giant bladder diverticulum due to Benign Prostatic Hypertrophy was made by abdominal ultrasound at Emergency Room, and afterwards was confirmed by cystography. A trabeculated wall and a diverticulum at the posterior side was seen with the cystography. The diverticulum full of urine couldn't be emptied due to a narrow diverticular neck and the rectum was obstructed. When a urethral catheter was put in, the symptoms of intestinal obstruction disappeared 800 ml of urine were passed through the catheter and the rectum compression was released; the gas was allowed to pass through the bowel and it's seen in plain X-Ray. This case is presented, considering its unusual this way of presentation of a giant bladder diverticulum. We have reviewed the literature en Medline since 1966 and we have not found a similar case.

Abstract
It is true that appearance of prostate abscesses is currently not so frequent due to the antibiotic therapy available to stop any kind of infectious process which may trigger abscess formation. Even so, it is important to channel right from the beginning the correct diagnosis and treatment in order to avoid, as far as possible, any complications that may derive from the process. This paper deals with the case of a young patient diagnosed in our service with a prostate abscess, and faced with that suspicion we advocated the use of transrectal ultrasound (TRU) as the method for diagnostic imaging. Also, TRU offers great help as guidance in the transperineal puncture, so as to drain the purulent content. It should not be forgotten the valuable information provided by ultrasound to confirm that the treatment used was effective.

Abstract
Primary renal aspergillosis is an extremely rare entity. Only 19 cases have been reported, 3 of them in patients with AIDS. We report one new case of renal aspergillosis in a patient with AIDS. His disease pattern was multiple bilateral renal abscesses with a normal excretory pathway. The treatment established was percutaneous drainage and systemic antifungal drugs. He had a bad evolution and died 14 weeks after diagnosis. In the previously reported cases of aspergillosis in patients with AIDS, the manifestation was unilateral renal abscess.

Abstract
Nuclear morphometry was performed in 159 adenocarcinomas of the kidney. The mean and SD of the following nuclear parameters were calculated: area, perimeter, major axis, minor axis and a shape factor. Median survival, including all stages, was 72 months and cumulative survival at 5, 10 and 15 years of 50, 42 and 33%, respectively. Values of morphometric parameters, except for shape factor, tend to increase in proportion to stage. Nuclear area was the best parameter to predict the variability in survival time. The Cox regression model was performed for each stage, and the relationship with length of survival time was studied. For stage T1-2 N0 M0, nuclear area was the only variable chosen as an independent significant predictor of outcome. For the rest of the stages, no variables were selected as predictors at any significant level.

Abstract
A holographic optical system for checking human depth perception is proposed. The system does not use any kind of dissociative element; it uses incoherent light for the reconstruction of holograms and allows the binocular disparity to vary from 0 to 650 arcsec. The depth perception of observers can be checked in conditions closer to normal life.

Abstract
The relationship of post-operatively determined prostatic gland weight and that calculated prior the procedure, by means of abdominal ultrasound techniques using the "ellipsoid method", has been studied in 88 patients undergoing retropubic adenectomy. The regression line was nearly optimal, Y = 0.946 X + 2.295, and the correlation coefficient between both weight measures was r = 0.915. Abdominal ultrasound examinations are a simple, quick and safe means to evaluate prostate weight, prior to deciding the type of surgery (open adenectomy or transurethral resection) for prostate adenoma.

Abstract
The present paper is a review of 71 cases of uretero-vaginal fistulae secondary to pelvic surgery which were treated in the Urology Unit of our hospital. Surgical management of these fistula intrinsically depends on their number, location and severity. The results obtained by the different techniques were analyzed, emphasizing their merit when using the Turner-Warwick technique (uretero-cystoneostomy on psoic bladder) and any urodynamic troubles this technique can bring about when used bilaterally in patients from radical gynaecological surgery.

Abstract
Since Caine demonstrated the presence of alpha-adrenergic receptors in prostate tissue in 1975, an alpha-blocker capable of producing maximum relaxation of prostatic tissue with minimum side effects has been sought. Prazosin, a selective alpha-1 blocking agent, must meet these requirements. We report the results of a study undertaken in 28 patients with benign hyperplasia of the prostate demonstrated by flowmetry, clinically and by ultrasound. A significant improvement was observed in all patients except for the ultrasound measured prostate size, which remained unchanged. Undesired effects were observed in 36% of the patients. Despite the initial improvement, 89.3% had abandoned treatment at 1 year principally owing to deterioration of the clinical picture and because they were submitted to surgery (the majority) or treatment with other drugs. We can conclude from our results that prazosin is useful for short-term therapy; i.e., until the patient can be referred for surgery.

Abstract
The paper presents the results obtained with endovesical dimethylsulphoxide in the treatment of interstitial cystitis in 30 women. Up to 80% patients showed clinical improvement with an average of 10 installations. Volume of maximal vesical capacity was increased in 24 patients (80%), the increase being greater than 100 cc in 10 cases. Presently, 24 (80%) patients remain under treatment, 14 with one instillation monthly and 10 once every six months. Six patients are fully asymptomatic without treatment after an average symptoms-free interval of 32 months. Since this is directly related to a decrease both in pain and miction frequency, the increase in vesical capacity appears to be a good improvement index. Dimethylsulphoxide in neither a healing nor a definite therapy but it seems to be effective in the management of this unknown disease.

Abstract
Sclerosant therapy for different pathological conditions (testicular hydrocele, pneumothorax) is a little known and scantily used procedure in the clinical setting. We have developed a surgical procedure in the dog that permits reproducing adult hydrocele. This experimental model is useful for morphometric assessment of the sclerosant effects of the commonly used agents (magnesium silicate hydrate, carbolic acid, ethanolamine oleate, hydroxytetracycline chlorhydrate and quinacrine chlorhydrate). Our results show that the degree of sclerosis achieved with quinacrine and hydrotetracycline is significantly superior to that obtained with other agents.

Abstract
Following some reports concerning the possible influence of ABO blood groups on constitutional types and different features of human pathology, we have investigated if there are relationships between ABO blood groups and bladder tumors. Our findings show that tumoral behavior in patients with bladder carcinoma and blood group O has a tendency to an increased aggressivity with higher tumoral grade and more relapses than what is seen in tumors of patients with A blood group. Although this difference is not statistically significant, we believe that blood group ABO should be considered as a constitutional prognostic factor in bladder carcinoma and further investigations in this field are needed.

Abstract
We performed a comparative study between the monobactam antibiotic aztreonam and the aminoglycoside tobramycin in patients diagnosed as having acute pyelonephritis. The respective doses were 1 gr. IM daily for 7 days, and 100 mgr. IM q 12 h for the same period of time. Clinically, 100% of uncomplicated acute pyelonephritis and 87.5% of complicated infections cured with aztreonam. Tobramycin achieved an 80% cure rate for both types of infections. Microbiologically aztreonam was effective in all uncomplicated acute pyelonephritis, and in 69.56% of the complicated cases (overall microbiological cure rate = 78.7%). The therapeutic failures were ascribable to infections from S. faecalis, an organism naturally resistant to aztreonam. Thus, the microbiological cure rate was 84.2% in complicated pyelonephritis from organisms sensitive to this antimicrobial. The microbiological cure rate for tobramycin was 70% in acute uncomplicated, and 80% in complicated infections. We observed a good clinical and biological tolerance to both antimicrobials. No side effects were observed. Serum and blood biochemical analyses, and coagulation tests revealed no changes.
