Abstract
PURPOSE/OBJECTIVE(S) Peer review is an essential step in clinical quality assurance and can impact patient safety and treatment outcomes. Most published data on peer review is from developed nations, with little data on peer review from low middle income countries (LMIC). Major challenges to peer review can include a lack of time, expertise and commitment from team members. With increasing access to advanced technology in LMIC, peer review is becoming more important to maintain quality and standard of care. We evaluated cloud-based e- peer review (Varian) in our network of hospitals in India with an aim to see feasibility and impact on care. MATERIALS/METHODS Four of 15 centers across India were selected for this pilot study. All team members were trained on the platform prior to implementation. New cases for the week treated with definitive intent were selected by the dosimetrist. The link to the cases were sent through email to reviewing physicians. Various aspects which were reviewed for each case were.1) Work up & staging (Documents were scanned and loaded).2) Treatment intent & prescription.3) Target contours.4) Normal Organ at risk contours.5) Dose- Volume -Histogram (DVH) with clinical goals attached. Cases were marked as "Not Appropriate", "Appropriate", "Appropriate with minor finding", "Represent with major revisions" as per volume and plan review. RESULTS Over a period of 2 months, a total of 80 cases underwent e-Peer Review at our network of hospitals prior to the start of treatment. Median turnover time (like from link sent to time to completion of review) was 48 (6-360) hours. Mean time taken by physician for review was 9 minutes (range 3 to15). 31.2% of cases were accepted without any changes, 51.9 % had a minor change and 16.9 % cases had major changes. Most frequent reason of major changes was contouring corrections 16.9%. 31% of major changes underwent recontouring and replanning before initiation of treatment. CONCLUSION Peer review was feasible in our network through this e-peer review system, with average turnover time and mean time taken for review of 48 hours & 9 min respectively. Peer review led to significant changes which could impact patient care delivery and outcome. The ability to review cases asynchronously via this cloud-based e-peer review system, helped to ease the burden of scheduling between treating and reviewing physician. We plan to implement this across the remaining centers in our network.

Outcomes of Alternative Reservoir Placement in the Lateral Retroperitoneum During Inflatable Penile Prosthesis Placement. Urology 2021; 152:35-41. [PMID: 33647306 DOI: 10.1016/j.urology.2021.02.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 02/02/2021] [Accepted: 02/16/2021] [Indexed: 01/31/2023]
Abstract
OBJECTIVES To describe outcomes of reservoir placement, exchange, and extraction from the lateral retroperitoneum (LR) in complex patients with a three-piece inflatable penile prosthesis (IPP). METHODS A retrospective chart review was performed on all patients that underwent placement of an IPP from 2009 to 2019. Patients with placement of the reservoir in the LR were identified. Intraoperative complications during reservoir placement, exchange, or removal, reservoir-related outcomes, and secondary device-related outcomes were collated and compared to patients who underwent traditional Space of Retzius reservoir placement. RESULTS A total of 587 men underwent primary IPP placement with 321 patients undergoing reservoir placement in the SOR and 266 in the LR. No significant differences were found in intra-operative reservoir-related outcomes (P=.272) between the 2 groups during placement, replacement, or extraction. Bowel injury occurred in 1 patient in the LR group during placement. No significant differences were found in postoperative reservoir complications (P= .534). Both groups each had one instance of patient reported bulge and pain at reservoir site (P= .6777). Two (0.6%) patients in the SOR group and 3 (1.1%) patients in the LR group had a reservoir failure or leak. There was a trend towards a lower rate of device infections in the LR group (1.9%) compared to the SOR group (4.7%) (P= .063). There were no significant differences in overall device mechanical failure rates between both groups (P= .919). CONCLUSIONS Reservoir placement in the LR is safe in patients with complex pelvic anatomy with equivalent device durability and no difference in surgical outcomes compared to standard retropubic reservoir placement.

Gene set enrichment analysis of α-amylase and α-glucosidase inhibitors of Cassia glauca. J Diabetes Metab Disord 2021; 19:683-689. [PMID: 33520796 DOI: 10.1007/s40200-020-00538-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Accepted: 04/29/2020] [Indexed: 11/25/2022]
Abstract
Background The present study aimed to evaluate in vitro α-amylase and α-glucosidase inhibitory activity of various extracts of Cassia glauca, predict the binding affinity of multiple phytoconstituents with both enzymes via in silico molecular docking and identify the probably modulated pathways by the lead hit. Methods Different extracts of Cassia glauca i.e. acetone, ethanol, and aqueous extracts were evaluated for α-amylase and α-glucosidase inhibitory activity using in vitro method in which starch and 4-Nitrophenyl β-D-glucopyranoside were used as substrate respectively. Similarly, the docking study was performed using autodock4 to predict the binding affinity of phytoconstituents with α-amylase and α-glucosidase. After docking, ten different poses were obtained for the ligand molecule. Among them, the pose of ligand molecule with the lowest binding energy was visualized in Discovery Studio 2019. Results and conclusion Among the multiple extracts, the aqueous extract showed the highest α-amylase (IC50:652.10 ± 20.09) and α-glucosidase (IC50:482.46 ± 8.70) inhibitory activity. Similarly, cassiaoccidentalin B was predicted to have the highest binding affinity with both enzymes. The potency of aqueous extract to inhibit α-amylase and α-glucosidase could be due to multiple water-soluble compounds like saponins, flavonoids, and glycosides.

Three-Piece Inflatable Penile Prosthesis Placement Following Pelvic Radiation: Technical Considerations and Contemporary Outcomes. J Sex Med 2018; 15:1049-1054. [PMID: 29731428 DOI: 10.1016/j.jsxm.2018.04.634] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2018] [Revised: 03/31/2018] [Accepted: 04/13/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Pelvic radiation is a known risk factor for the development and progression of erectile dysfunction. When medical therapy fails, the 3-piece inflatable penile prosthesis (IPP) can offer patients a definitive treatment option. Because of radiation-induced vascular changes and tissue fibrosis, a careful surgical approach is necessary to avoid intraoperative complications and attain successful outcomes. Despite its widespread use in prostate cancer treatment, there are no contemporary studies examining the effects that pelvic radiation can have on 3-piece IPP placement and device survival. AIM To present technical considerations and contemporary outcomes of placing a 3-piece IPP for refractory erectile dysfunction in patients with a history of pelvic radiation. METHODS We retrospectively reviewed 78 patients who underwent placement of a 3-piece IPP (AMS 700; Boston Scientific, Marlborough, MA, USA) after being treated with pelvic radiotherapy from 2003 through 2016. All patients had been treated with external beam and/or brachytherapy for treatment of prostate malignancy. An infrapubic approach was used in all patients, with reservoir placement in the space of Retzius or in the lateral retroperitoneal space. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection and mechanical failure were examined and statistical analysis was performed. OUTCOMES Rates of device infection, revision surgery, and reservoir complications. RESULTS No intraoperative complications were observed. After a mean follow-up of 49.0 months (6.6-116.8), 2 patients developed an infection of their prosthesis that required explantation. These patients underwent successful IPP removal and immediate reimplantation. 11 patients (14.1%) required revision surgery (pump replacement, n = 4; pump relocation, n = 2; cylinder replacement, n = 4; reservoir replacement owing to leak, n = 1). No reservoir-related complications such as herniation or erosion into adjacent structures were observed. CLINICAL IMPLICATIONS The 3-piece IPP can be placed safely in a broad range of patients treated with pelvic radiotherapy. STRENGTHS AND LIMITATIONS This study describes contemporary long-term outcomes of the IPP in patients treated with pelvic radiation and includes patients with prior pelvic surgery and artificial urinary sphincter, which are commonly encountered in practice. It is limited by its single-center experience and lacks a comparison group of patients. Objective patient satisfaction data were not available for inclusion. CONCLUSIONS The 3-piece IPP can be placed successfully in patients with a history of pelvic radiation without a significant increase in infectious complications, reservoir erosion, or mechanical failure compared with the global literature.

Abstract
Skin is generally damaged through genetic and environmental factors such as smoking, exposure to xenobiotics, heat, hormonal changes, and ultraviolet light. These factors can cause skin diseases. Cissus quadrangularis Linn. (CQ) has been used in folk medicine for the treatment of skin diseases since ancient times. Taking in to consideration the medicinal properties exhibited by this genus, it was decided to investigate the anti-cancer activity of CQ. Extracts obtained from CQ and their phenolic contents were subjected to in vitro evaluation of anticancer activity by using A431 (skin epidermoid carcinoma, human) cell line. The A431 cells were treated with different extracts of CQ in a dose dependent manner. Out of five extracts, the acetone extract demonstrated significant anti-cancer activity in the A431 cell line. Hexane, chloroform, ethyl acetate and methanol extracts also exhibited cytotoxicity but to a comparatively lesser extent than the acetone extract. The GI(50) value of the acetone extract was found to be 8 μg mL(-1), whereas GI(50) value of purified fraction of acetone extract, termed as AFCQ (active acetone fraction of CQ) with respect to A431 cells, was found to be 4.8 μg mL(-1). Furthermore, the mechanism of anticancer activity exhibited by AFCQ was investigated by comparing its effect with the standard anticancer drug Doxorubicin (DOX) by evaluating the status of apoptotic markers after treatment of A431 cells with AFCQ and DOX. Bax-Bcl-2 ratio along with the release of cytochrome c from mitochondria to cytoplasm, which is a hallmark of apoptosis, was also evaluated. Cleavage of PARP revealed that AFCQ induces apoptosis in A431 cells with reference to DOX.

Abstract
OBJECTIVES The aim of this study has been to investigate the possible antihyperlipidemic effect of Salacia chinensis root extract in triton (400mg/kg b.w.)-induced and atherogenic diet-induced hyperlipidemic rats. MATERIALS AND METHODS Petroleum ether (60-80°C), chloroform, ethanol and aqueous extracts of Salacia chinensis roots were evaluated for antihyperlipidemic activity in triton- and atherogenic diet-induced hyperlipidemic rats. A comparison was also made between the action of Salacia chinensis root extract and a known antihyperlipidemic drug simvastatin (10 mg/kg body wt.). The results of the study were expressed as mean± S.E. and data was analyzed by using one way analysis of variance test (ANOVA) followed by Dunnett's t-test for multiple comparisons. Values with P < 0.05 were considered as significant. RESULTS Oral administration of 500 mg/kg body wt. of the chloroform extract and alcoholic extract of Salacia chinensis root exhibited a significant reduction (P<0.01) in serum lipid parameters like total cholesterol, triglycerides, low density lipoprotein (LDL), very low density lipopreotein (VLDL) and increase in high density lipoprotein (HDL) in hyperlipidemic rats of both models as compared to hyperlipidemic control statistically. These extracts were found to possess better antihyperlipidemic potential as compared to pet ether and aqueous extract. CONCLUSIONS Our results demonstrated that chloroform and alcoholic extract of Salacia chinensis roots possessed significant antihyperlipidemic activity and hence it could be a potential herbal medicine as adjuvant with existing therapy for the treatment of hyperlipidemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cissus quadrangularis is an ancient medicinal plant. It is an active ingredient of one Ayurvedic formula called "Laksha Gogglu". Its stem is used in food preparation in India. Traditionally it is used to treat various diseases like asthma, indigestion, ear diseases, irregular menstruation, skin diseases, piles, fractured bones, etc. AIM OF THE STUDY This study aimed to evaluate the ability of the plant extracts to inhibit cycloxygenase (COX-1), cycloxygenase (COX-2), and 5-lipoxygenase (5-LOX) enzyme activity. Western blot analysis was also carried out in the quest to determine the effect of active acetone fraction of Cissus quadrangularis (AFCQ) on proinflammatory mediators as acetone extract is found to be the most effective in this study. MATERIALS AND METHODS The differential extract of the stem were tested for enzyme inhibition of COX and 5-LOX using spectroscopic and polarigraphic method. Effective acetone extract was partially purified by silica column, one of the active fraction showed dual inhibition against COX and 5-LOX. Western blotting shows downregulation of proinflammatory mediators as well as upregulation of phase-II enzymes. RESULTS AFCQ extract showed COX and 5-LOX inhibition with IC(50) values of 7 μg/ml, 0.4 μg/ml, and 20 μg/ml for COX-1, COX-2 and 5-LOX respectively. It also showed anti-inflammatory activity on RAW 264.7 cell line with IC(50) value 65 μg/ml. In addition to this it is showing inhibition of proinflammatory mediators like iNOS and TNFα, along with translocation of Nrf-2 and upregulation of HO-1. CONCLUSION AFCQ is a COX and 5-LOX inhibitor isolated from the stems of Cissus quadrangularis. It is also effectively downregulate the iNOS, TNFα, and upregulation of HO-1.

Abstract
Objectives: The aim of this study was to investigate the antidiabetic activity of Crateva nurvala stem bark (family: Capparidaceae) extracts in alloxan-induced diabetic albino rats. A comparison was made between the action of different extracts of C. nurvala and a known antidiabetic drug glibenclamide (600 μg/kg b. wt.). An oral glucose tolerance test (OGTT) was also performed in diabetic rats. Materials and Methods: The petroleum ether, chloroform, alcohol, and aqueous extracts of C. nurvala stem bark were obtained by simple maceration method and were subjected to standardization by following pharmacognostical and phytochemical screening methods. Dose selection was made on the basis of acute oral toxicity study (50–5000 mg/kg b. wt.) as per Organization for Economic Co-operation and Development (OECD) guidelines. Results and Conclusions: C. nurvala petroleum ether extract (CNPEE) and ethanolic extract (CNEE) showed significant (P< 0.001) antidiabetic activities. In alloxan-induced model, blood glucose level of these extracts on seventh day of study were CNPEE (126.33±13.703 mg/dl) and CNEE (126.66±13.012 mg/dl) when compared with diabetic control (413.50±4.752 mg/dl) and chloroform extract (320.83±13.516 mg/dl). In OGGT model (glucose loaded rats), CNPEE showed a glucose level of 178.83±3.070 mg/dl after 30 min and 131.66±2.486 mg/dl after 90 min, whereas CNEE showed 173.66±4.224 mg/dl after 30 min and 115.50±3.394 mg/dl after 90 min. These extracts also prevented body weight loss in diabetic rats. The drug has the potential to act as an antidiabetic drug.

Abstract
PURPOSE We evaluated the face, content and construct validity of the novel da Vinci® Skills Simulator™ using the da Vinci Si™ Surgeon Console as the surgeon interface. MATERIALS AND METHODS We evaluated a novel robotic surgical simulator for robotic surgery using the da Vinci Si Surgeon Console and Mimic™ virtual reality. Subjects were categorized as novice-no surgical training, intermediate-surgical training with fewer than 100 robotic cases or expert-100 or more primary surgeon robotic cases. Each participant completed 10 virtual reality exercises with 3 repetitions and a questionnaire with a 1 to 10 visual analog scale to assess simulator realism (face validity) and training usefulness (content validity). The simulator recorded performance based on specific metrics. The performance of experts, intermediates and novices was compared (construct validity) using the Kruskal-Wallis test. RESULTS We studied 16 novices, 32 intermediates with a median surgical experience of 6 years (range 1 to 37) and a median of 0 robotic cases (range 0 to 50), and 15 experts with a median of 315 robotic cases (range 100 to 800). Participants rated the virtual reality and console experience as very realistic (median visual analog scale score 8/10) while expert surgeons rated the simulator as a very useful training tool for residents (10/10) and fellows (9/10). Experts outperformed intermediates and novices in almost all metrics (median overall score 88.3% vs 75.6% and 62.1%, respectively, between group p<0.001). CONCLUSIONS We confirmed the face, content and construct validity of a novel robotic skill simulator that uses the da Vinci Si Surgeon Console. Although it is currently limited to basic skill training, this device is likely to influence robotic surgical training across specialties.

Abstract
The present study explores the hepatoprotective activity of various extracts of Ferula asafoetida, Momordica charantia Linn and Nardostachys jatamansi against experimental hepatotoxicity. Polyherbal suspensions were formulated using extracts showing significant activity and evaluated for both physicochemical and hepatoprotective activity in comparison with LIV-52 as standard. Petroleum ether (60-80 degrees ), chloroform, benzene, ethanol and aqueous extracts of Ferula asafetida, Momordica charantia Linn and Nardostachys jatamansi were evaluated for hepatoprotective activity against carbon tetrachloride-induced liver toxicity in Wistar rats. Polyherbal suspensions were prepared by the trituration method using a suspending agent and other excipients. Formulation F3 has shown significant hepatoprotective effect by reducing the elevated serum enzyme levels such as glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and alkaline phosphatase. These biochemical observations were supplemented by histopathological examination of liver sections. Various parameters evaluated for all formulations were within the official specifications. Experimental data suggested that treatment with formulation F3 enhances the recovery from carbon tetra chloride-induced hepatotoxicity. From these results it may be concluded that the F3 formulation (containing chloroform, petroleum ether and aqueous extracts of Ferula asafetida, petroleum ether and ethanol extracts of Momordica charantia Linn. and petroleum ether and ethanol extracts of Nardostachys jatamansi) demonstrated significant hepatoprotective activity, that might be due to combined effect of all these extracts.

Abstract
The antidiabetic activity of Pongamia pinnata ( Family: Leguminosae) leaf extracts was investigated in alloxan-induced diabetic albino rats. A comparison was made between the action of different extracts of P. pinnata and a known antidiabetic drug glibenclamide (600 μg/kg b. wt.). An oral glucose tolerance test (OGTT) was also performed in experimental diabetic rats. The petroleum ether, chloroform, alcohol and aqueous extracts of P. pinnata were obtained by simple maceration method and were subjected to standardization using pharmacognostical and phytochemical screening methods. Dose selection was made on the basis of acute oral toxicity study (50-5000 mg/kg b. w.) as per OECD guidelines. P. pinnata ethanolic extract (PPEE) and aqueous extract (PPAE) showed significant (P < 0.001) antidiabetic activity. In alloxan-induced model, blood glucose levels of these extracts on 7th day of the study were 155.83 ± 11.211mg/dl (PPEE) and 132.00 ± 4.955mg/dl (PPAE) in comparison of diabetic control (413.50 ± 4.752mg/dl) and chloroform extract (210.83 ± 14.912mg/dl). In glucose loaded rats, PPEE exhibited glucose level of 164.50 ± 6.350mg/dl after 30 min and 156.50 ± 4.089mg/dl after 90 min, whereas the levels in PPAE treated animals were 176 ± 3.724mg/dl after 30 min and 110.33 ± 6.687mg/dl after 90 min. These extracts also prevented body weight loss in diabetic rats. The drug has the potential to act as an antidiabetic drug.

Abstract
The study describes an attempt to record leptospirosis in Raichur taluk/district, in Karnataka, by serological test such as microscopic test and IgM by ELISA. A house to house survey was done in six villages of Krishna river basin. Cases were interviewed regarding chief complaints like, fever, headache and oliguria, age, sex and treatment given with diclofenac, doxycycline, tetracycline and vitamin B complex. A total of 1516 cases were treated. The age of the patients ranged between 10 and 71 years. Most of them were agricultural workers. Out of 15 blood samples 12 samples sent to DHO Office, 3 were negative for leptospirosis, the density of rats were increased in all villages, the mode of transmission was food and water contamination, duration of incubation period was 5 to 10 days. Health education, for the community was undertaken to take measures against rats. Causative agent may be Leptospirosis interrogans, 3 cases were referred to Civil Hospital, Raichur and Navodaya Medical College, Raichur. Community participation was excellent. This study showed the presence of leptospirosis among the community of 6 villages, the disease is posing health hazards for agricultural workers in Raichur taluka villages.

Abstract
Albumin microparticles have found many applications in diagnosis and treatment in recent years and more than 100 diagnostic agents and drugs have been incorporated into albumin microparticles. In the present study, bovine serum albumin (BSA) based microparticles bearing captopril were prepared by an emulsification-heat stabilization technique. Four batches of microparticles with varying ratio of drug and polymer were prepared. The prepared microparticles were studied for drug loading, particle size distribution, in vitro release characteristics, in vivo tissue distribution study and stability studies. The microparticles had mean diameter between 2 and 11 microm of which more than 70% were below 5 microm and incorporation efficiency of 41-63% was obtained. In vitro release profile for formulations containing captopril-loaded albumin microparticles with heat stabilizing technique shows slow controlled release up to 24 h. The in vivo result of drug-loaded microparticles showed preferential drug targeting to liver followed by lungs, kidneys and spleen. Stability studies showed that maximum drug content and closest in vitro release to initial data were found in the formulation stored at 4 degrees C. In the present study, captopril-loaded BSA microparticles were prepared and targeted to various organs to a satisfactory level and were found to be stable at 4 degrees C.
