Chemotherapy for prostate cancer: implementing early systemic therapy to improve outcomes

Prostate cancer remains a significant health concern for men in the USA as it is a leading cancer diagnosis and a cause of death. With the use of prostate-specific antigen or screening, a stage migration has occurred with an increase in the number of men diagnosed with early-stage disease. The optimal primary management of these men is evolving, but despite adequate local treatment a significant percentage will develop either biochemical or clinical evidence of recurrent disease. Several criteria for risk stratification have been developed, thus, improving the ability to identify a high-risk population. Small studies have been reported demonstrating the feasibility of neoadjuvant or adjuvant chemotherapy in conjunction with either radiation or radical prostatectomy in this high-risk population, and large phase III studies are ongoing. With the advent of life-prolonging chemotherapy in the hormone-refractory setting, attention must now also be given to early-stage disease so as to develop multi-modality approaches with the hope of increasing survival and ultimately providing a cure.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46931/1/280_2005_Article_103.pd

Laparoscopic Cholecystectomy (LC) and the Risk Factors in the Conversion to Open Cholecystectomy (OC) Surgery: Jordan Statistical Review

This study aimed at exploring the risk factors in the conversion from laparoscopic cholecystectomy (LC) to open cholecystectomy (OC) Surgery, and overview the Jordanian statistics for patients over the year 2016 in the Jordanian hospitals. Results show that male gender with symptomatic cholelithiasis was associated with higher conversion rates. And results also showed that the age (>65 years) to be a risk factor for increased perioperative morbidity and conversion rates because of associated acute cholecystitis. Laparoscopic cholecystectomy is a safe procedure in patients, with no increased risk of complications compared with the open procedure. The recovery is faster and the hospital stay, shorter

A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks

Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computa‑ tion requirements. In this research, we present a Certificateless Online/Offline Signature (COOS) mechanism for UWSNs. The proposed scheme is based on the concept of a hyperelliptic curves cryptosystem, which offers the same degree of security as RSA, bilinear pairing, and elliptic curve cryptosystems (ECC) but with a smaller key size. In addition, the proposed scheme was proven secure in the random oracle model under the hyperelliptic curve discrete logarithm problem. A se‑ curity analysis was also carried out, as well as comparisons with appropriate current online/offline signature schemes. The comparison demonstrated that the proposed scheme is superior to the exist‑ ing schemes in terms of both security and efficiency. Additionally, we also employed the fuzzy‑based Evaluation‑based Distance from Average Solutions (EDAS) technique to demonstrate the effective‑ ness of the proposed scheme.publishedVersio

Frequency of cognitive impairment in patients with parkinson\u27s disease

Introduction More than its motor symptoms, cognitive impairment is being increasingly identified as a cause of worse functional outcome, morbidity and mortality, and caregiver dependence in Parkinson\u27s disease (PD). The aim of this study was to identify the frequency of cognitive decline and evaluate the factors associated with it. Methods In this cross-sectional study, 124 PD patients fulfilling the United Kingdom Parkinson\u27s Disease Society Brain Bank Clinical Diagnostic Criteria were included. Motor and non-motor symptoms were recorded. Disease duration, age at the time of onset, and severity of disease on Hoehn and Yahr Scale (HY scale) were recorded. Data was entered and analyzed using SPSSs v. 22.0. Results The ratio of men to women was 7.2:1. The mean age of the participants was 64 ± 10 years (range: 38-82 years). Rigidity (n = 121; 97.5%), bradykinesia (n = 119; 95.9%), and tremor (n = 11; 90.3%) were the three most common symptoms. Cognitive impairment was present in 45 (36.3%) patients. Cognitive decline was more frequent in patients of age less than 50 years at the time of disease onset (p \u3c 0.00001) and in those with disease duration more than 10 years (p = 0.00001). Patients with longer disease duration had more severe disease (stage III or above on HY scale; p = 0.008). Conclusion Motor symptoms such as rigidity, bradykinesia, and tremor remain the most frequent clinical presentation among Pakistani Parkinson\u27s patients. One-third of these patients have cognitive dysfunction. Early age at the time of disease onset and longer duration of disease were associated with cognitive impairmen

Potential of sewage irrigation for heavy metal contamination in soil–wheat grain system: ecological risk and environmental fate

Anthropogenic activities are major cause of environmental pollution with significant risks for human health that can lead to excessive pollutant entry into the terrestrial ecosystem. The present study was conducted to evaluate the impact of bioaccumulation of carcinogenic metals (Cd, Ni, Co, Cr), and mineral elements (Zn, Fe, Mn and Cu) in the wheat irrigated with sewage water and different environmental traits (bio-concentration factor, pollution load index, daily intake of metals, health risk index) were compared to understand the ultimate sink of these toxic metals. The Cd was in range of 2.89–3.04 mg/kg in soil. The Fe and Mn were in range of 2.87–4.16 and 1.54–1.66 mg/kg, while Zn varies from 0.18 to 1.21 mg/kg, respectively. Grain exhibit higher concentration (3.31 mg/kg) of Zn while lowest (1.02 mg/kg) of Ni. Bio-concentration factor (BCF) values of Cd, Ni, Fe and Mn being less than 1.0 indicates lower Ni, Cd, Fe and Mn concentration in grains. BCF varies from 0.46 to 0.80 mg/kg for Cd, 0.31 to 0.41 mg/kg for Ni, 0.29 to 0.44 mg/kg for Fe and 0.15 to 0.73 mg/kg for Mn. Pollution load index (PLI) of Zn and Cd was lowest and highest among the evaluated trace metals, respectively. Health risk index was highest for Zn and Cd while it was < 1 for all other metals that showed no danger to human health. Enrichment factor (EF) of Zn was highest followed by Cd while found lowest in Mn. To minimize the health risks in humans, regular monitoring of wheat crop irrigated with wastewater is highly recommended.Universidade de Vigo/CISU

Contrast medium administration and image acquisition parameters in renal CT angiography: what radiologists need to know

Over the last decade, exponential advances in computed tomography (CT) technology have resulted in improved spatial and temporal resolution. Faster image acquisition enabled renal CT angiography to become a viable and effective noninvasive alternative in diagnosing renal vascular pathologies. However, with these advances, new challenges in contrast media administration have emerged. Poor synchronization between scanner and contrast media administration have reduced the consistency in image quality with poor spatial and contrast resolution. Comprehensive understanding of contrast media dynamics is essential in the design and implementation of contrast administration and image acquisition protocols. This review includes an overview of the parameters affecting renal artery opacification and current protocol strategies to achieve optimal image quality during renal CT angiography with iodinated contrast media, with current safety issues highlighted

Vorinostat in advanced prostate cancer patients progressing on prior chemotherapy (National Cancer Institute Trial 6862)

BACKGROUND: This phase 2 trial was designed to evaluate the efficacy of vorinostat in chemotherapy-pretreated patients with metastatic castration-resistant prostate cancer. METHODS: Patients with disease progression on 1 prior chemotherapy, a prostate-specific antigen (PSA) ≥5 ng/mL, and adequate organ function were treated with 400 mg vorinostat orally daily. The primary endpoint was the 6-month progression rate. Secondary endpoints included safety, rate of PSA decline, objective response, overall survival, and effects of vorinostat on serum interleukin-6 (IL-6) levels. RESULTS: Twenty-seven eligible patients were accrued. The median number of cycles delivered was 2 (range, 1-7). All patients were taken off therapy before 6 months. The best objective response in the eligible patient was stable disease in 2 (7%) patients. No PSA decline of ≥50% was observed. There was 1 grade 4 adverse event (AE), and 44% of patients experienced grade 3 adverse events. The most common adverse events were fatigue (81%), nausea (74%), anorexia (59%), vomiting (33%), diarrhea (33%), and weight loss (26%). Median time to progression and overall survival were 2.8 and 11.7 months, respectively. Median IL-6 levels (pg/mL) were higher in patients removed from the protocol for toxicity compared with progression at all time points, including baseline (5.2 vs 2.1, P = .02), Day 15 Cycle 1 (9.5 vs 2.2, P = .01), Day 1 Cycle 2 (9.8 vs 2.2, P = .01), and end of study (11.0 vs 2.9, P = .09). CONCLUSIONS: Vorinostat at this dose was associated with significant toxicities limiting efficacy assessment in this patient population. The significant association between IL-6 levels and removal from the study for toxicities warrants further investigation.
