1 ± 5.4 and was statistically significant when compared with nonresponders (P less then 0.001). CT scan has 66% accuracy and PET has 82% accuracy at post three cycles NACT in predicting the pathological response. PET/CT had higher sensitivity and specificity when compared with CT findings alone in response evaluation. Conclusion PET/CT scan can be considered as a sensitive tool for predicting pCRs and further larger trials are required to establish these findings.

Methods Twenty-five (age range 22-82 years) biopsy-proven patients of DLBCL with only nodal involvement who underwent staging 18FDG PET-CT scan were included in this study. Whole-body PET-CT performed at staging and PET-derived metabolic parameters, namely MTV and TLG of all FDG-avid lesions, were calculated for each patient. Total MTV was computed by summing the volumes of all FDG-avid lesions, the volume of each being calculated at threshold of 42% of the maximum standardized uptake value (SUV) using a semi-automatic software. TLG was calculated by summing the product of volume and SUVmean of each lesion. Patients were followed up to a period of 5 years and data obtained were divided into two groups, with recurrence and without recurrence. Results Six patients developed recurrence on follow-up and 19 patients remained disease free on follow-up. The area under a curve (AUC) for MTV was 0.825 and for TLG was 0.623 suggesting MTV to be a good prognostic indicator and TLG poor indicator for predicting recurrence in these patients. In pairwise comparison of both the receiver operator characteristics, it was found that the difference between the AUCs of MTV and TLG was statistically significant (P = 0.0349). Thus, indicating MTV is a statistically better indicator than TLG. Conclusion MTV is a better prognostic indicator than TLG in DLBCL patients.

The aim of this prospective observational study was to determine the incremental value of Ga-68 PSMA-11 PET/CT over multiparametric magnetic resonance imaging (mpMRI) in the locoregional staging of intermediate- and high-risk PC using histopathology from radical prostatectomy specimens as a gold standard. Materials and Methods This was a prospective study, including 35 patients with biopsy-proven prostate carcinoma. All the patients underwent whole-body Ga-68 PSMA-11 PET/CT scans along with mpMRI including a dedicated pelvic imaging protocol within a time window of ± 10 days. The reference standard was based on histopathological results, postprostatectomy. RAD001 research buy Results All 35 patients showed Ga-68 PSMA-11-avid disease, of which 29 underwent radical prosar Medicine.What differentiates local governments that implement water policies on equity and the environment? Analyzing a 2015 national survey of 1,897 U.S. municipalities, we find municipalities that own their water utilities are more likely to report policies to protect low-income residents from disconnection and implement water resource management. Respondents from 8% of municipalities report protecting residents from disconnection. State economic regulation of publicly owned utilities and Democrat-majority municipal governments are positively associated with local policies to protect low-income households from shutoffs but bear no association with resource management. Both local public ownership of utilities and state economic regulation may play a role in meeting certain local water policy goals. © 2020 Published by Elsevier Ltd.A common study design for comparing the diagnostic performance of imaging modalities is to obtain modality-specific ratings from multiple readers of multiple cases whose true statuses are known. Typically, there is overlap between the modalities, readers, and/or cases for which special analytical methods are needed to perform statistical comparisons. We describe our new R software package MRMCaov, which is designed for multi-reader multi-case comparisons of two or more imaging modalities. The software allows for the comparison of reader performance metrics, such as area under the receiver operating characteristic curve (ROC AUC), with analysis of variance methods originally proposed by Obuchowski and Rockette (1995) and later unified and improved by Hillis and colleagues (2005, 2007, 2008, 2018). MRMCaov is an open-source package with an integrated command-line interface for performing multi-reader multi-case statistical analysis, plotting, and presenting results. link2 Features of the package include (1) ROC curves estimated parametrically or non-parametrically; (2) reader-specific ROC curves and performance metrics; (3) user-definable performance metrics; (4) modality-specific estimates of mean performance along with confidence intervals and p-values for statistical comparisons; (5) support for factorial, nested, or partially paired study designs; (6) inference for random readers and cases, random readers and fixed cases, or fixed readers and random cases; (7) DeLong, jackknife, or unbiased covariance estimation; and (8) compatibility with Microsoft Windows, Mac OS, and Linux.I examine the relationship between unhappiness and age using data from eight well-being data files on nearly fourteen million respondents across forty European countries and the United States and 168 countries from the Gallup World Poll. I use twenty different individual characterizations of unhappiness including many not good mental health days; anxiety; worry; loneliness; sadness; stress; pain; strain, depression and bad nerves; phobias and panic; being downhearted; having restless sleep; losing confidence in oneself; not being able to overcome difficulties; being under strain; being unhappy; feeling a failure; feeling left out; feeling tense; and thinking of yourself as a worthless person. I also analyze responses to a further general attitudinal measure regarding whether the situation in the respondent's country is getting worse. Responses to all these unhappiness questions show a, ceteris paribus, hill shape in age, with controls and many also do so with limited controls for time and country. Unhappiness is hill-shaped in age and the average age where the maximum occurs is 49 with or without controls. There is an unhappiness curve. © 2020 Elsevier B.V.

The literature on the topic is still fragmented; the features of the emerging paradigm appear to be a contested territory among different academic disciplines. This study assumes a value chain perspective to analyze the evolutionary trajectories of manufacturing companies. We developed a Delphi-based scenario analysis involving 76 experts from academia and practice. The results highlight the most common expectations as well as controversial issues in terms of emerging business models, size, barriers to entry, vertical integration, rent distribution, and geographical location of activities. link3 Eight scenarios provide a concise outlook on the range of possible futures. These scenarios are based on four main drivers which stem from the experts' comments demand characteristics, transparency of data among value chain participants, maturity of additive manufacturing and advanced robotics, and penetration of smart products. Researchers can derive from our study a series of hypotheses and opportunities for future research on Industry 4.0. Managers and policymakers can leverage the scenarios in long-term strategic planning. © 2020 Elsevier Inc.

We evaluate the growth of dysfunctional policymaking in the U.S. and propose a countering approach. Policy failures often reflect partisan policy stalemate, errors or unintended consequences, polarized extremism or imbalance, or partisan reversals with changes in power. Extremes in partisanship are not new historically, but growing policy failures due to negative partisanship have now severely damaged public trust. More "party blind" conditions in policy formulation may be able to renew a more productive social contract. We propose a disruptive presidential leadership approach of bipartisan inclusion to seek to reframe the partisan divides, counter negative partisanship and extremes, re-establish better policymaking interactions, and improve governance and policy outcomes. Dysfunctional policymaking has been attributed to Republicans and Democrats in a Prisoner's Dilemma. Iterated Prisoner's Dilemmas often lead to higher rates of cooperation, and similarly, historical policymaking included greater cooperation, but in recent decades the bipartisan norms of governance have substantially eroded. We describe three complementary explanations, which suggest that non-cooperative partisan policymaking has become self-reinforcing, and institutional changes to promote cooperation should focus on lowering the risk-adjusted cost-benefit ratio, making cooperation safer and more attractive for policymakers. © Springer Science+Business Media, LLC, part of Springer Nature 2020.Ventriculoperitoneal (VP) shunt operation is a common neurosurgical procedure applied for managing intracranial hydrocephalus. Migration of a distal catheter is an uncommon complication, and related gastric perforation is rarely reported. Herein, we report the case of gastric perforation in a patient with VP shunt who presented with fever. The distal catheter within the stomach was confirmed by preoperative computed tomographic scan of abdomen and gastric endoscopy. Surgical intervention and appropriate antibiotics management enabled patient recovery. This case emphasizes the importance of early recognition and surgical intervention in this rare complication related to the shunt procedure.OBJECTIVE To review the dynamics of neuroscience research in the Kingdom of Saudi Arabia (KSA) from 2013-2018.
