Molecular profiling of mucosal tissue associated microbiota in patients manifesting acute exacerbations and remission stage of ulcerative colitis.

Dysbiosis of intestinal microflora has been postulated in ulcerative colitis (UC), which is characterized by imbalance of mucosal tissue associated bacterial communities. However, the specific changes in mucosal microflora during different stages of UC are still unknown. The aim of the current study was to investigate the changes in mucosal tissue associated microbiota during acute exacerbations and remission stages of UC. The mucosal microbiota associated with colon biopsy of 12 patients suffering from UC (exacerbated stage) and the follow-up samples from the same patients (remission stage) as well as non-IBD subjects was studied using 16S rRNA gene-based sequencing and quantitative PCR. The total bacterial count in patients suffering from exacerbated phase of UC was observed to be two fold lower compared to that of the non-IBD subjects (p = 0.0049, Wilcox on matched-pairs signed rank tests). Bacterial genera including Stenotrophomonas, Parabacteroides, Elizabethkingia, Pseudomonas, Micrococcus, Ochrobactrum and Achromobacter were significantly higher in abundance during exacerbated phase of UC as compared to remission phase. The alterations in bacterial diversity with an increase in the abnormal microbial communities signify the extent of dysbiosis in mucosal microbiota in patients suffering from UC. Our study helps in identifying the specific genera dominating the microbiota during the disease and thus lays a basis for further investigation of the possible role of these bacteria in pathogenesis of UC.

Impact of the United States Preventive Services Task Force 'D' recommendation on prostate cancer screening and staging.

PURPOSE OF REVIEW: In 2012, the United States Preventive Services Task Force (USPSTF) issued a grade 'D' recommendation against the use of routine prostate-specific antigen (PSA)-based screening for any men. This recommendation reflects critical misinterpretations of the available evidence base regarding benefits and harms of PSA screening and has influenced the nationwide landscape of prostate cancer screening, diagnosis, and treatment. RECENT FINDINGS: Following the USPSTF recommendation, a substantial decline in PSA screening was noted for all age groups. Similarly, overall rates of prostate biopsy and prostate cancer incidence have significantly decreased with a shift toward higher grade and stage disease upon diagnosis. Concurrently, the incidence of metastatic prostate cancer has significantly risen in the United States. These trends are concerning particularly for the younger men with occult high-grade disease who are expected to benefit the most from early detection and definitive prostate cancer treatment. SUMMARY: These emerging trends in PSA screening and prostate cancer incidence following the USPSTF recommendation may have significant public health implications. Due to the long natural history of the disease, a long-term follow-up is needed to provide a better understanding on the implications of such recommendations on disease progression and mortality rates in prostate cancer patients. The future of US screening policy should reflect a targeted 'smarter' screening strategy rather than dichotomizing the decision between 'screen all' or 'screen none'.

Differences in Muscle Activation and Kinematics Between Cable-Based and Selectorized Weight Training.

Signorile, JF, Rendos, NK, Heredia Vargas, HH, Alipio, TC, Regis, RC, Eltoukhy, MM, Nargund, RS, and Romero, MA. Differences in muscle activation and kinematics between cable-based and selectorized weight training. J Strength Cond Res 31(2): 313-322, 2017-Cable resistance training machines are showing resurgent popularity and allow greater number of degrees of freedom than typical selectorized equipment. Given that specific kinetic chains are used during distinct activities of daily living (ADL), cable machines may provide more effective interventions for some ADL, whereas others may be best addressed using selectorized equipment. This study examined differences in activity levels (root mean square of the EMG [rmsEMG]) of 6 major muscles (pectoralis major, PM; anterior deltoid, AD; biceps brachii, BB; rectus abdominis, RA; external obliques, EO; and triceps brachii, TB) and kinematics of multiple joints between a cable and standard selectorized machines during the biceps curl, the chest press, and the overhead press performed at 1.5 seconds per contractile stage. Fifteen individuals (9 men, 6 women; mean age ± SD, 24.33 ± 4.88 years) participated. Machine order was randomized. Significant differences favoring cable training were seen for PM and AD during biceps curl; BB, AD, and EO for chest press; and BB and EO during overhead press (p ≤ 0.05). Greater starting and ending angles were seen for the elbow and shoulder joints during selectorized biceps curl, whereas hip and knee starting and ending angles were greater for cable machine during chest and overhead presses (p < 0.0001). Greater range of motion (ROM) favoring the cable machine was also evident (p < 0.0001). These results indicate that utilization patterns of selected muscles, joint angles, and ROMs can be varied because of machine application even when similar exercises are used, and therefore, these machines can be used selectively in training programs requiring specific motor or biomechanical patterns.

Gender differences in overactive bladder.

Overactive bladder (OAB) is a common condition in both women and men. Although prevalence's are similar in both genders, sex specific differences do exist in relation to individual OAB symptoms as well as degree of bother and quality of life. The added effect of prostatic enlargement in men leads to slightly different evaluation and treatment regimens in both genders. This review will examine the gender differences in OAB related to epidemiology, OAB evaluation, investigation and treatment. This information will assist the primary care physician in assessing and initiating treatment in patients with OAB. It will further the understanding of the spectrum of treatments available for OAB and assist in determining the appropriateness and timing of referral of such patients to a urologist.

Role of FDG PET/CT in Management of Patients with Prostate Cancer.

Prostate cancer is the second most common cancer in men worldwide. [18F]FDG PET/CT imaging, a well-known and effective technique for detecting malignancies, has not been considered a useful tool for prostate cancer imaging by many because of its perceived low [18F]FDG uptake. Incidentally detected focal [18F]FDG uptake in the prostate is not uncommon, and typically benign. Imaging features that would increase concern for an underlying prostatic carcinoma, include focal uptake in the periphery near the gland margin without calcifications. [18F]FDG PET/CT imaging provides little value in the initial staging of prostate cancer, particularly in the era of prostate specific membrane antigen (PSMA) radiotracer. In cases of biochemical recurrence, the value of [18F]FDG PET/CT increases notably when Grade group 4 or 5 and elevated PSA levels are present. Active research is underway for theranostic approaches to prostate cancer, including [177Lu]Lu-PSMA therapy. Dual tracer staging using FDG and PSMA imaging significantly enhances the accuracy of disease site assessment. Specifically, the addition of [18F]FDG PET/CT imaging allows for the evaluation of discordant disease (PSMA negative/FDG positive). The maximal benefit from [177Lu]Lu-PSMA therapy relies on significant PSMA accumulation across all disease sites, and the identification of discordant disease suggests that these patients may derive less benefit from the treatment. The genuine value of [18F]FDG PET/CT imaging lies in advanced prostate cancer, PSMA-negative disease, as a prognostic biomarker, and the realm of new targeted theranostic agents.

Administering [177Lu]Lu-PSMA-617 Prior to Radical Prostatectomy in Men with High-risk Localised Prostate Cancer (LuTectomy): A Single-centre, Single-arm, Phase 1/2 Study.

BACKGROUND: High-risk localised prostate cancer (HRCaP) has high rates of biochemical recurrence; [177Lu]Lu-PSMA-617 is effective in men with advanced prostate cancer. OBJECTIVE: To investigate the dosimetry, safety, and efficacy of upfront [177Lu]Lu-PSMA-617 in men with HRCaP prior to robotic radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS: In this single-arm, phase I/II trial, we recruited men with HRCaP (any of prostate-specific antigen [PSA] >20 ng/ml, International Society of Urological Pathology (ISUP) grade group [GG] 3-5, and ≥cT2c), with high tumour uptake on [68Ga]Ga-PSMA-11 positron emission tomography/computed tomography (PSMA PET/CT), and scheduled for RP. INTERVENTION: Cohort A (n = 10) received one cycle and cohort B (n = 10) received two cycles of [177Lu]Lu-PSMA-617 (5 GBq) followed by surgery 6 weeks later. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was tumour radiation absorbed dose. Adverse events (AEs; Common Terminology Criteria for Adverse Events (CTCAE) version 5.0), surgical safety (Clavien-Dindo), imaging, and biochemical responses were evaluated (ClinicalTrials.gov: NCT04430192). RESULTS AND LIMITATIONS: Between May 29, 2020 and April 28, 2022, 20 patients were enrolled. The median PSA was 18 ng/ml (interquartile range [IQR] 11-35), Eighteen (90%) had GG ≥3, and six (30%) had N1 disease. The median (IQR) highest tumour radiation absorbed dose after cycle 1 for all lesions was 35.5 Gy (19.5-50.1), with 19.6 Gy (11.3-48.4) delivered to the prostate. Five patients received radiation to lymph nodes. Nine (45%) patients achieved >50% PSA decline. The most common AEs related to [177Lu]Lu-PSMA-617 were grade 1 fatigue in eight (40%), nausea in seven (35%), dry mouth in six (30%), and thrombocytopenia in four (20%) patients. No grade 3/4 toxicities or Clavien 3-5 complications occurred. Limitations include small a sample size. CONCLUSIONS: In men with HRCaP and high prostate-specific membrane antigen (PSMA) expression, [177Lu]Lu-PSMA-617 delivered high levels of targeted radiation doses with few toxicities and without compromising surgical safety. Further studies of [177Lu]Lu-PSMA-617 in this population are worthwhile to determine whether meaningful long-term oncological benefits can be demonstrated. PATIENT SUMMARY: In this study, we demonstrate that up to two cycles of [177Lu]Lu-PSMA-617 given prior to radical prostatectomy in patients with high-risk localised prostate cancer are safe and deliver targeted doses of radiation to tumour-affected tissues. It is tolerated well with minimal treatment-related adverse events, and surgery is safe with a low rate of complications. Activity measured through PSA reduction, repeat PSMA PET/CT, and histological response is promising.

Arthrobotrys oligospora-mediated biological control of diseases of tomato (Lycopersicon esculentum Mill.) caused by Meloidogyne incognita and Rhizoctonia solani.

AIMS: To study the biocontrol potential of nematode-trapping fungus Arthrobotrys oligospora in protecting tomato (Lycopersicon esculentum Mill.) against Meloidogyne incognita and Rhizoctonia solani under greenhouse and field conditions. METHODS AND RESULTS: Five isolates of the nematode-trapping fungus Arthrobotrys oligospora isolated from different parts of India were tested against Meloidogyne incognita and Rhizoctonia solani in tomato (Lycopersicon esculentum Mill.) plants grown under greenhouse and field conditions. Arthrobotrys oligospora-treated plants showed enhanced growth in terms of shoot and root length and biomass, chlorophyll and total phenolic content and high phenylalanine ammonia lyase activity in comparison with M. incognita- and R. solani-inoculated plants. Biochemical profiling when correlated with disease severity and intensity in A. oligospora-treated and untreated plants indicate that A. oligospora VNS-1 offered significant disease reduction in terms of number of root galls, seedling mortality, lesion length, disease index, better plant growth and fruit yield as compared to M. incognita- and R. solani-challenged plants. CONCLUSION: The result established that A. oligospora VNS-1 has the potential to provide bioprotection agents against M. incognita and R. solani. SIGNIFICANCE AND IMPACT OF THE STUDY: Arthrobotrys oligospora can be a better environment friendly option and can be incorporated in the integrated disease management module of crop protection. Application of A. oligospora not only helps in the control of nematodes but also increases plant growth and enhances nutritional value of tomato fruits. Thus, it proves to be an excellent biocontrol as well as plant growth promoting agent.

Non-fat milk solids attenuate hypercholesterolemic effect of conjugated linoleic acid.

The present study instigates the notion that non-fat milk has a beneficial effect on hypercholesterolemia caused by dietary conjugated linoleic acid (CLA). Two groups of mice (6 per group) were fed synthetic CLA (predominantly a mixture of t10, c12 and c9, t11 isomers) at 1 % level in the diet with or without skim milk powder (SMP). Another group (control) was fed a similar diet without CLA and SMP. The study was conducted for 60 days (d). Daily feed intake and weekly body weight were recorded. Plasma lipid profile was determined monthly. At the conclusion of experiment, animals were sacrificed and liver tissue was removed to assay cholesterol and triacylglycerols (TAG). Following 60 day feeding, the plasma total cholesterol content increased significantly in CLA group (218 mg/dl) than in control group (167 mg/dl), while in CLA + SMP group (fed non-fat milk solids along with CLA), it was similar to that in control group. The fractions of high density lipoproteins (HDL) and low density lipoprotein + very low density lipoprotein (LDL + VLDL) cholesterol as well as triacylglycerols (TAG) in plasma increased in CLA group, but in CLA + SMP group it remained similar to the control levels. Thus, it is concluded that dietary CLA increases plasma cholesterol and TAG contents in mice on normocholesterolemic diet and the inclusion of non-fat milk solids reverses this effect.

Effect of Dental Varnishes in Prevention of Enamel Demineralization Adjacent to Orthodontic Brackets.

Aim: The aim of the current research was to assess the ability of different dental varnishes in averting enamel demineralization adjoining the orthodontic brackets. Materials and Methods: Seventy-five premolars devoid of dental caries that were subjected to extraction for orthodontic purposes were employed in this research. The surface of enamel was etched with 37% phosphoric acid and subjected to primer application. Individual brackets were placed on the midregion of the buccal surfaces of the premolars with Transbond™ XT adhesive. Postbracket bonding, the dry premolar tooth samples were set aside cautiously. The samples were then allocated to three groups: Group I: Duraphat Varnish, Group II: Clinpro XT Varnish, and Group III: Profluorid Varnish. Every sample was independently subjected to immersion in demineralizing solution for a period of 96 h at 37°C in an incubator. Areas of demineralization were evaluated by documenting the microhardness along the severed surface using a microhardness tester equipped with a Vickers diamond. Results: The highest surface microhardness was noted with Profluorid Varnish group at 328.48 ± 1.12 in pursuit by Clinpro XT Varnish group at 322.08 ± 0.04 as well as Duraphat Varnish group at 307.42 ± 0.28 with a statistically noteworthy dissimilarity amid the groups. Conclusion: In conclusion, the three varnishes employed had an influence on the prevention of enamel demineralization surrounding the orthodontic brackets. Profluorid varnish however exhibited maximum efficiency in avoiding enamel demineralization versus Clinpro XT varnish as well as Duraphat varnish group.

Evaluation of Microleakage of Stainless Steel Crowns and Pedo Jacket Crowns after Cementation With Different Luting Cements.

Aim: The present research was conducted to assess the microleakage of stainless steel crowns along with pedo jacket crowns following cementation with different luting cements. Materials and Methods: A total of 60 deciduous teeth subjected to extraction were employed in this in vitro research. These 60 specimens were randomly divided into two groups: Group I: Stainless steel crowns and Group II: Pedo Jacket crowns. Both crowns were subjected to cementation using self-cure resin-modified glass ionomer (RMGI) cement as well as by means of self-adhesive universal resin cement (RelyX luting cement). The specimens were subjected to storage in distilled water at 37°C for 24 h and were subjected to 500 thermal cycles between 5°C and 55°C using a dwell span of 30 s. Individual surfaces were assessed for the amount of dye infiltration at the boundaries by the side of the tooth-cement border beneath a stereomicroscope under 50× magnifying power. At the mesial and distal surfaces, the amount of microleakage was measured in micrometers (µm), and the mean value was computed for each sample. Results: Stainless steel crowns subject to cementation with RelyX luting cement exhibited the lowest microleakage (0.88 ± 0.78) versus self-cure RMGI cement (0.94 ± 0.78). There was no statistically significant difference found between the groups. Pedo Jacket crowns subject to cementation with RelyX luting cement exhibited the lowest microleakage (0.96. ± 0.32) while self-cure RMGI cement (1.83 ± 0.16) depicted the maximum microleakage. There was an extremely statistically noteworthy dissimilarity noted among the groups. Conclusion: The current research concluded that Pedo Jacket crowns subjected to cementation with RelyX luting cement can be regarded as an esthetically pleasing restorative alternative for numerous young patients. Applying RelyX luting cement to Pedo Jacket crowns provides a strong bolstering by composite materials that ensures the success of the therapy provided.

Histopathological spectrum of adult renal tumours: A single center experience and review of literature.

Background: Renal tumors constitute approximately 3% of all malignancies in adults. They form a heterogenous group with variable morphological, immunohistochemical, and molecular features. Aim: The objective of this study was to analyze the spectrum of adult renal tumors at a tertiary care center and study the demographic and histomorphological features. Materials and Methods: In this study, 55/87 nephrectomy specimens resected for adult renal tumors during a 1-year period were analyzed retrospectively. Results: There were 4 benign (7.2%) and 51 (92.7%) malignant tumors. There was a male preponderance with a male: female ratio of 3.42:1. The tumors were seen to occur equally in both kidneys. The most common tumor was clear cell renal cell carcinoma (RCC), the conventional type accounting for 65.5% of our study group. There were one each of multilocular cystic renal neoplasm of low malignant potential, papillary RCC, chromophobe RCC, Mit family RCC, oncocytoma and angiomyolipoma and two clear cell papillary RCC during this 1-year period. Uncommon tumors included neuroendocrine carcinoma (1), epithelioid angiomyolipoma (1), mixed epithelial stromal tumor (1), Ewings sarcoma (2), and glomangioma (1). Five cases of urothelial carcinoma of renal pelvis/ureter also were present. Conclusion: This article gives an overview of the spectrum of adult renal tumors at a tertiary care center with an in-depth literature review providing recent advances in each category of tumors.

CE: Using Smart IV Infusion Pumps Outside of Patient Rooms.

ABSTRACT: The COVID-19 pandemic has created unique challenges for health care workers, who have demonstrated dedication, collaboration, and innovation in response. In this article, the authors describe an important nursing innovation they employed at Montefiore Medical Center in the Bronx, New York, during the spring 2020 COVID-19 surge: the relocation of smart IV infusion pumps outside of patient rooms. The goals of this innovation were to improve delivery of care, conserve personal protective equipment, limit the spread of the virus, and protect staff from exposure. The authors discuss the initial concerns that arose regarding the safety and efficacy of this practice; the research they conducted with other colleagues in nursing, pharmacy, infection control, and patient safety in the face of scant clinical literature relevant to the difficult circumstances the pandemic created; and the strategies they ultimately employed to ensure that this practice maintained safety and efficacy.

Correlation of TIRADS and Bethesda Scoring Systems with Final Histopathology of Thyroid Nodules - An Institutional Experience.

Fine needle aspiration cytology (FNAC) reduces the number of unnecessary thyroid surgeries for patients with benign nodules and appropriately triages patients with thyroid cancer to appropriate treatment. This was a observational study done on cases presenting with clinical suspicion of thyroid malignancy which underwent ultrasonography followed by FNAC of thyroid nodule. Ultrasonographic characterization of nodules was based on Thyroid Imaging Reporting and Data System (TIRADS) and cytology reporting was based on Bethesda system. All recruited patients underwent thyroidectomy. Pre-operative cytology and ultrasonography features were compared with final histopathology report. In our study, Bethesda system of cytology reporting for thyroid nodules had a better sensitivity, specificity and diagnostic accuracy than TIRADS system of ultrasound reporting. Bethesda system in FNAC had a larger area under the ROC curve (0.91) as compared to ultrasound TIRADS (0.70). Malignancy rate of TIRADS 5 nodules was 97.1% with significant p value (0.022). 100% of Bethesda VI lesions were malignant according to final histopathology report. Ultrasound TIRADS could pre-operatively predict malignancy in 63.6% of indeterminate thyroid nodules which were malignant according to post-operative histopathology. The overall concordance of ultrasound TIRADS, Bethesda system and histopathology was 69.8%. Higher TIRADS and Bethesda scoring among thyroid nodules was associated with increased risk of malignancy. US TIRADS is a good predictor of malignancy in indeterminate thyroid nodules.

Deciphering Cadmium (Cd) Tolerance in Newly Isolated Bacterial Strain, Ochrobactrum intermedium BB12, and Its Role in Alleviation of Cd Stress in Spinach Plant (Spinacia oleracea L.).

A cadmium (Cd)-tolerant bacterium Ochrobactrum intermedium BB12 was isolated from sewage waste collected from the municipal sewage dumping site of Bhopal, India. The bacterium showed multiple heavy metal tolerance ability and had the highest minimum inhibitory concentration of 150 mg L-1 of Cd. Growth kinetics, biosorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectroscopy studies on BB12 in the presence of Cd suggested biosorption as primary mode of interaction. SEM and TEM studies revealed surface deposition of Cd. FTIR spectra indicated nitrogen atom in exopolysaccharides secreted by BB12 to be the main site for Cd attachment. The potential of BB12 to alleviate the impact of Cd toxicity in spinach plants (Spinacia oleracea L.) var. F1-MULAYAM grown in the soil containing Cd at 25, 50, and 75 mg kg-1 was evaluated. Without bacterial inoculation, plants showed delayed germination, decrease in the chlorophyll content, and stunted growth at 50 and 75 mg kg-1 Cd content. Bacterial inoculation, however, resulted in the early germination, increased chlorophyll, and increase in shoot (28.33%) and root fresh weight (72.60%) at 50 mg kg-1 of Cd concentration after 75 days of sowing. Due to bacterial inoculation, elevated proline accumulation and lowered down superoxide dismutase (SOD) enzyme activity was observed in the Cd-stressed plants. The isolate BB12 was capable of alleviating Cd from the soil by biosorption as evident from significant reduction in the uptake/translocation and bioaccumulation of Cd in bacteria itself and in the plant parts of treated spinach. Potential PGP prospects and heavy metal bioremediation capability of BB12 can make the environmental application of the organism a promising approach to reduce Cd toxicity in the crops grown in metal-contaminated soils.

The revolving door penalty: is it a matter of time?

The revolving door of readmissions keeps spinning for patients who report symptoms of shortness of breath.

Temporal dynamics of innate and adaptive immune responses in broiler birds to oral delivered chitosan nanoparticle-based Salmonella subunit antigens.

Salmonella enterica serovar Enteritidis (S. Enteritidis, SE) infection of poultry causes a significant risk to public health through contamination of meat and eggs. Current Salmonella vaccines have failed to provide strong mucosal immunity in the intestines to reduce Salmonella shedding and food contamination. Considering the short lifespan of broilers, an easy-to-deliver, safe and effective Salmonella vaccine is urgently needed. Our goal in this study was to demonstrate the ability of chitosan nanoparticle (CNP) vaccine delivery platform in activating immune response to Salmonella antigens in broilers inoculated orally. In an initial study, soluble whole antigen of SE entrapped in CNP was inoculated but the specific immune responses were poor. Therefore, the CNP entrapped immunogenic outer membrane proteins (OMP) and flagellin (FLA) of SE and surface conjugated with FLA [CNP-(OMP + FLA)] was developed. In broilers inoculated orally with CNP-(OMP + FLA) formulation once or twice, we monitored the temporal expression of innate immune molecules and antigen specific lymphocyte proliferation. In the cecal tonsils of CNP-(OMP + FLA) inoculated birds, we observed enhanced expression of mRNA coding Toll-like receptors (TLRs)- 1, 4, 5, and 7, especially at dpv 21. In addition, both OMP and FLA specific lymphocytes proliferation at dpv 7 and 21 by CNP-(OMP + FLA) were enhanced in the spleen. In conclusion, CNP-(OMP + FLA) formulation augmented both innate and lymphocyte responses in orally inoculated broilers. Further studies are needed to determine the candidate subunit CNP vaccine's efficacy in a challenge trial.

Evaluation of CpG-ODN-adjuvanted polyanhydride-based intranasal influenza nanovaccine in pigs.

Influenza results in significant economic loss in the swine industry each year. A broadly protective swine influenza vaccine would have the dual benefit of protecting pigs from influenza A viruses (IAVs) and limiting their possible zoonotic transmission to humans. In this study, we developed polyanhydride nanoparticles-based swine influenza vaccine (KAg + CpG-nanovaccine) co-encapsulating inacticated/killed soluble antigen (KAg) and Toll-like receptor (TLR)-9 agonist (CpG-ODN). The immunogenicity and protective efficacy of KAg + CpG-nanovaccine was compared with KAg vaccine containing five-times greater quantity of antigens following heterologous virus challenge. Prime-boost intranasally delivered KAg + CpG-nanovaccine induced significantly higher levels of cross-reactive antigen-specific IgA antibody responses in the nasal cavity, greater lymphoproliferative response in peripheral blood mononuclear cells (PBMCs), and higher IFN-γ secretion during antigen-induced recall responses of PBMCs and tracheobronchial lymph nodes cells compared to those immunized with KAg alone. Importantly, KAg + CpG-nanovaccine provided better protective efficacy through a significant reduction in influenza-induced fever, 16-fold reduction of nasal virus shedding and 80-fold reduction in lung virus titers compared to those immunized with soluble KAg. Our results indicated that CpG-ODN-adjuvanted polyanhydride nanovaccine can induce higher mucosal antibody and cellular immune responses in pigs; and provide better protection as compared with intranasally delivered soluble KAg.

Practice patterns of primary EBRT with and without ADT in prostate cancer treatment.

BACKGROUND: Androgen deprivation therapy (ADT) has been shown to improve survival for men with intermediate and high-risk prostate cancer undergoing external-beam radiation therapy (EBRT). Using data from a community-based prospective disease registry, we investigated usage of EBRT with or without neoadjuvant ADT. METHODS: The CaPSURE database contains 14,863 men with prostate cancer, including 1337 men diagnosed between 1990 and 2014 with localized disease who received EBRT as primary treatment. Prostate cancer risk was calculated using the CAPRA score. Patient characteristics were compared using the Mantel-Haenszel chi-square test for trend and analysis of variance. RESULTS: Between 1990 and 2014, 14,010 men were diagnosed with localized disease within the CaPSURE registry. Of those, 1337 underwent EBRT. Patients had a median age of 71 years. The use of ADT in addition to EBRT increased from 24% in 1990 to 60% in 1996 with a decrease seen to 47% in 2011. Men receiving ADT have differing clinical characteristics including higher PSA at diagnosis, higher Gleason grade, and higher CAPRA scores. Median ADT duration was 4 months. CONCLUSIONS: The use of ADT in conjunction with primary EBRT has increased in frequency and duration since 1990. Men receiving ADT have higher risk characteristics than those receiving EBRT alone. There is substantial variability in use of ADT in clinical practice.

Automating the Capture of Structured Pathology Data for Prostate Cancer Clinical Care and Research.

PURPOSE: Cancer pathology findings are critical for many aspects of care but are often locked away as unstructured free text. Our objective was to develop a natural language processing (NLP) system to extract prostate pathology details from postoperative pathology reports and a parallel structured data entry process for use by urologists during routine documentation care and compare accuracy when compared with manual abstraction and concordance between NLP and clinician-entered approaches. MATERIALS AND METHODS: From February 2016, clinicians used note templates with custom structured data elements (SDEs) during routine clinical care for men with prostate cancer. We also developed an NLP algorithm to parse radical prostatectomy pathology reports and extract structured data. We compared accuracy of clinician-entered SDEs and NLP-parsed data to manual abstraction as a gold standard and compared concordance (Cohen's κ) between approaches assuming no gold standard. RESULTS: There were 523 patients with NLP-extracted data, 319 with SDE data, and 555 with manually abstracted data. For Gleason scores, NLP and clinician SDE accuracy was 95.6% and 95.8%, respectively, compared with manual abstraction, with concordance of 0.93 (95% CI, 0.89 to 0.98). For margin status, extracapsular extension, and seminal vesicle invasion, stage, and lymph node status, NLP accuracy was 94.8% to 100%, SDE accuracy was 87.7% to 100%, and concordance between NLP and SDE ranged from 0.92 to 1.0. CONCLUSION: We show that a real-world deployment of an NLP algorithm to extract pathology data and structured data entry by clinicians during routine clinical care in a busy clinical practice can generate accurate data when compared with manual abstraction for some, but not all, components of a prostate pathology report.

Missed diagnosis of a wooden intra-orbital foreign body.

Intraorbital foreign bodies often present a confusing clinical picture. Wooden foreign bodies are notorious for remaining quiescent for a long time, before presenting with a variety of complications. The wound of entry may often be small and self-sealing. Wooden foreign bodies also show a propensity to break during attempted removal. Intraorbital wood is often not detected by standard diagnostic tests like the computed tomography scan, adding to the diagnostic dilemma. The presence of an intraorbital mass with a discharging sinus should evoke suspicion of a retained organic foreign body, regardless of the time interval between the trauma and current presentation. It is imperative to maintain a high index of suspicion in such cases to avoid misdiagnosis. We report an unusual case of a missed wooden intraorbital foreign body, which spontaneously extruded after five years.
