Postoperative Cytology for Drained Fluid from the Pancreatic Bed After “Curative” Resection of Pancreatic Cancers: Does It Predict Both the Patient's Prognosis and the Site of Cancer Recurrence?

Objective To evaluate the postoperative cytology of drained fluid from the pancreatic bed as a predictive indicator of local recurrence after curative (R0) resection of pancreatic cancer. Summary Background Data The pancreatic bed offers a common site of cancer recurrence (local recurrence), even after curative (R0) resection is performed for pancreatic cancer. If local recurrence is thereby predicted precisely, soon after surgery, we have a chance to treat it by adding radiation or some other locoregional therapy before it can grow or spread beyond the pancreatic bed. However, there have been no previous reports of cytology performed on the drained fluid after pancreatectomy. Methods This study includes 94 patients who had shown negative results in the peritoneal washing cytology before resection and subsequently received pancreatectomies for pancreatic tumors. They consisted of 12 benign tumors, 17 noninvasive or minimally invasive carcinomas and 65 invasive ductal carcinomas (R0 = 58; R1/2 = 7). Postoperatively, the drained fluid from the pancreatic bed was collected for 24 hours and used for cytologic examination. The cytologic results were examined in association with the histopathology of the resected tumor, patient's survival, and mode of cancer recurrence, including local recurrence. Results Patients with benign tumors or noninvasive/minimally invasive carcinomas had negative result in cytology, and none of them have died of local recurrence (limited to the pancreatic bed) to date. However, patients with invasive ductal carcinoma revealed higher cytology-positive rates: 28% (16/58) in curative (R0) resection; and 71% (5/7) in noncurative (R1/2) resection. Among 58 patients with R0 resection, the 3-year survival rate was 14% in 16 cytology-positive patients and 55% in 42 cytology-negative patients (P < 0.05). The 3-year cumulative rate of local recurrence was 85% and 23%, respectively (P < 0.05). Compared with other histopathologic parameters obtained from the resected specimens, the drain cytology was more specific in predicting the subsequent development of local recurrence. Conclusions Drain-cytology was a quick examination that enabled us to specifically indicate both minute residual cancer and subsequent development of local recurrence even after R0 resection of pancreatic cancer.
Content and Completeness of Care Plans After Implementation of Standardized Nursing Terminologies and Computerized Records

&NA; The nursing process and standardized nursing terminologies are essential elements to structure nursing documentation in daily nursing information management. The aim of this study was to describe sustainability and whether and how standardized nursing terminologies, in handwritten versus preprinted versus computerized nursing care plans, changed the content and completeness of documented nursing care. Three audits of patient records were performed: a pretest (n = 291) before a yearlong implementation of standardized nursing terminologies in nursing care plans followed by two posttests: (1) 3 weeks after implementation of nursing terminologies (n = 299) and (2) 22 months after implementation of nursing terminologies and 8 months after implementation of a computerized system (n = 281) in a university hospital. Content and completeness of documented nursing care improved after implementation of standardized nursing terminologies. Documentation of nursing care plans, signs and symptoms, related factors, and nursing interventions increased, whereas mean number of nursing diagnoses per patient did not change between audits. Computerized nursing care plans had the biggest impact, with more variety of nursing diagnoses and increased documentation of signs and symptoms, related factors, and nursing interventions. The use of standardized nursing terminologies improved nursing content in the nursing care plans. Moreover, computerized nursing care plans, in comparison with handwritten and preprinted care plans, increased documentation completeness.
Impact of ageing on lymphatic cerebrospinal fluid absorption in the rat

Several parameters associated with the cerebrospinal fluid (CSF) system show a change in the later stages of life, including elevated CSF outflow resistance. The latter implies a CSF absorption deficit. As a significant portion of CSF absorption occurs into extracranial lymphatic vessels located in the olfactory turbinates, the purpose of this study was to determine whether any age‐related impediments to CSF absorption existed at this location. In previous studies, we observed rapid movement of the CSF tracer into the olfactory turbinates in young rats (peaking 30 min after injection), with the concentration of the tracer being much higher in the turbinates than in any other tissue measured. In the study reported here, 125I‐human serum albumin was injected into the lateral ventricles of 3‐, 6‐, 12‐ and 19‐month‐old Fisher 344 rats. The animals were sacrificed at various times after injection of the radioactive tracer, and appropriate tissue samples were extracted. At 30 min post injection, the average tracer values expressed as per cent injected/g tissue were 6.68 ± 0.42 (n = 9, 3 months), 4.78 ± 0.67 (n = 9, 6 months), 2.49 ± 0.31 (n = 9, 12 months) and 2.42 ± 0.72 (n = 9, 19 months). We conclude that lymphatic CSF transport declines significantly with age. In concert with the known drop in CSF formation, the reduction in lymphatic CSF absorption may contribute to a decrease in CSF turnover in the elderly.
The COMMAND trial of cognitive therapy to prevent harmful compliance with command hallucinations: predictors of outcome and mediators of change

Background Acting on harmful command hallucinations is a major clinical concern. Our COMMAND CBT trial approximately halved the rate of harmful compliance (OR = 0.45, 95% CI 0.23–0.88, p = 0.021). The focus of the therapy was a single mechanism, the power dimension of voice appraisal, was also significantly reduced. We hypothesised that voice power differential (between voice and voice hearer) was the mediator of the treatment effect. Methods The trial sample (n = 197) was used. A logistic regression model predicting 18-month compliance was used to identify predictors, and an exploratory principal component analysis (PCA) of baseline variables used as potential predictors (confounders) in their own right. Stata's paramed command used to obtain estimates of the direct, indirect and total effects of treatment. Results Voice omnipotence was the best predictor although the PCA identified a highly predictive cognitive-affective dimension comprising: voices’ power, childhood trauma, depression and self-harm. In the mediation analysis, the indirect effect of treatment was fully explained by its effect on the hypothesised mediator: voice power differential. Conclusion Voice power and treatment allocation were the best predictors of harmful compliance up to 18 months; post-treatment, voice power differential measured at nine months was the mediator of the effect of treatment on compliance at 18 months.
Effects of enalapril and losartan in left ventricular remodeling after acute myocardial infarction: a possible mechanism of prevention of cardiac events by angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in high-risk myocardial infarction.

BACKGROUND Angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) have been shown to have a significant cardioprotective effect in high-risk patients after myocardial infarction (MI). However, there are few data on the effects of these drugs on left-ventricular (LV) remodeling after MI in Japanese patients. METHODS AND RESULTS We randomly assigned 100 patients with anterior-wall MI who had received reperfusion therapy to treatment with either enalapril (n=50) or losartan (n=50), and calculated the LV ejection fraction (LVEF) and LV end-diastolic volume index (LVEDVI) in these patients at baseline and after 6 months of treatment. While a significant increase in the LVEF as compared with that at the baseline was observed in both groups, no significant difference was found in the rate of change of this parameter between the two groups. However, inverse correlations were observed between the baseline LVEF and LVEDVI and also the rates of change of the two parameters, suggesting that the greater the compromise of the LV function at baseline, the greater the preventive effect of both classes of drugs on LV remodeling. CONCLUSION The results of this study suggest that neither enalapril nor losartan is superior to the other in terms of the effect on LV remodeling after MI in Japanese patients. In addition, the suppressive effect of both classes of drugs on LV remodeling was greater in patients with more extensive infarction and greater compromise of LV function at baseline.
A Transaction Cost Analysis of Hybrid Forms of Contracting: Implications for Prediction and Performance,

Abstract : Transaction Cost Economics (TCE) theories of exchange have proven to be a useful tool for understanding a variety of economic relationships. The TCE model has been especially useful in explaining the boundaries of economic institutions with regard to 'make' or 'buy' decisions. However, the markets and hierarchies paradigm has been limited in explaining non- market and non-hierarchical relationships which are termed 'hybrid' forms of governance. TCE theory indicates that as assets become more specific, as uncertainty becomes more acute and as transactions become incomplete, the hierarchical form of governance becomes predominant so that control of the transaction can be internalized to the organization. However, evidence suggests that this is not the case in many transactions where long-term contracts substitute for either the market or hierarchy form of governance. Long-term contracts suffice if they sufficiently allow parties to maintain control of the transaction through the contract. Consequently, long-term contracts have to be 'complete' enough to legally allow control while negating opportunism of the transactors. The more incomplete the contract, the less control the transactors have in the relationship. While 'incompleteness' of long-term contracts is an important concept in the hybrid form of TCE theory, neither it nor the efficiency of these long-term contracts has been adequately addressed in previous research.
MODELING THE ADAPTIVE POTENTIAL OF ISOLATED POPULATIONS: EXPERIMENTAL SIMULATIONS USING DROSOPHILA

Abstract The genetic variability underlying many morphological and stress resistance traits may largely depend on the effects of genetic drift balanced by polygenic mutation. This model of adaptive potential has played a central role in the minimum viable population size concept and has been used to predict the effective population size necessary to prevent extinction within changing environments. However, there have been few long-term experimental studies of adaptive potential within isolated populations, and no study has thus far provided an experimental test of the drift-mutation model of quantitative genetic variation. Using the sternopleural bristle number of Drosophila melanogaster as a model quantitative trait, we performed repeated measurements of adaptive potential on 15 replicate populations of two and 10 male-female pairs over 30 and 77 generations, respectively. Declines in adaptive potential were analyzed by comparing observed and expected changes in realized heritability over time. The only significant model deviation occurred immediately after bottlenecks of two pairs, in which greater than expected declines in realized heritability were observed. This result suggests that changes in allelic diversity during bottleneck events may be as important as changes in heterozygosity in determining adaptive potential. Drift-mutation model expectations were otherwise realized over all generations. Our results validate the use of the drift-mutation model as a tool for understanding the dynamics of adaptive potential for peripheral fitness characters, but suggest caution in applying this model to recently bottlenecked populations.
Real β-Convergence of Transition Countries

The aim of the paper is to analyze whether there is and, possibly, how strong the gross domestic product (GDP) β-convergence is in a group that includes most postcommunist countries, which, we believe, are a relatively homogeneous group compared to all countries. We use country-level panel data from the 1960-2009 period. In order to verify the β-convergence hypothesis, we use the Bayesian averaging of classical estimates (BACE) approach proposed by Sala-i-Martin et al. (2004). We estimate a convergence model without imposing an a priori assumption regarding the exact set of growth factors used as control variables in the regression. We use twenty potential growth factors (and an initial GDP level as an additional factor) and additional dummy variables (for Central and Eastern European and Commonwealth of Independent States countries) to further reduce the heterogeneity of the considered population. Our research allows us to robustly confirm the existence of β-convergence at a rate of 1.5 percent to 2 percent per annum. Using the BACE approach, we also identify the most relevant growth factors to be included in the β-convergence model. Our results are not controversial but in some respects differ from those present in the mainstream literature.
Parental feeding practices and children's weight

Global increases in childhood obesity rates demand that we tackle the problem from many directions. One promising avenue is to explore the impact of parental feeding practices, particularly those related to parental control over children's intake. In this paper, we review studies of parent feeding and child adiposity covering a range of research methodologies (case‐control studies, high risk studies, cross‐sectional community studies and longitudinal cohort studies). We also present results from a cross‐sectional community study of pre‐schoolers (n = 439) and a longitudinal study of twins from ages of 4 to 7 years (n = 3175 pairs). We conclude that parents are more likely to encourage leaner than heavier children to eat, but relationships between adiposity and other parental feeding strategies are unclear. We suggest that future research should: (i) explore the impact of a comprehensive range of authoritative and authoritarian parental feeding behaviours, preferably using the same validated scales consistently across studies; (ii) test the generalisation of existing findings to diverse socio‐economic and ethnic groups and (iii) utilise experimental, prospective and genetic methodologies to explore the causal relationships between parental feeding and child weight. We describe current projects in our own group that are designed to take forward these recommendations.
The Relationship between Change of Direction Speed in the Frontal Plane, Power, Reactive Strength, and Strength

International Journal of Exercise Science 7(4) : 260-270, 2014. Change-of-direction speed (CODS) is an important quality to performance in multi-direction sports. The relationship between CODS in the frontal plane and power, strength, and reactive strength is largely unstudied. Twenty-three male college students participated in this study. The study used a Pearson’s product-moment correlation to measure the relationship between CODS, power, strength, and reactive strength. A lateral shuffle test was used as the measure of CODS. A lateral hop for distance was used as the measure of power in the frontal plane. A countermovement vertical jump test was used as the measure of power in the sagittal plane. A depth jump was used as the measure of reactive strength in the sagittal plane. A 3RM squat test was used as the measure of strength. There was a moderate relationship between the lateral shuffle test and the lateral hop (r =.541, p = .008 and r =.567, p = .005), but no significant relationships with the countermovement vertical jump, depth jump, or squat test. These results suggest that power should be trained in all planes to improve CODS performance in multi-direction sports, and that CODS should be trained in its sport-specific context.
Self-reported Diagnosis of Rheumatoid Arthritis or Ankylosing Spondylitis Has Low Accuracy: Data from the Nord-Trøndelag Health Study

Objective. Self-reported diagnoses of inflammatory arthritis are not accurate. The primary study aim was to ascertain self-reported diagnoses of rheumatoid arthritis (RA) and ankylosing spondylitis (AS) in the Norwegian population-based Nord-Trøndelag Health Study (HUNT) using hospital case files. The secondary aim was to provide updated estimates of the prevalence and incidence of RA and AS. Methods. All inhabitants ≥ 20 years old from the county of Nord-Trøndelag were invited. Data from 70,805 unique participants from HUNT2 (1995–1997) and HUNT3 (2006–2008) were included. For participants who self-reported RA or AS, case files from all 3 hospitals in the catchment area were evaluated using standardized diagnostic criteria. Results. Of 2703 self-reported cases of RA, 19.1% were verified in hospital files. Of 1064 self-reported cases of AS, 15.8% were verified. Of 259 cases self-reporting both RA and AS, 8.1% had RA and 5.4% had AS. Overall, a self-report of 1 or both diagnoses could not be verified in 82.1%, including 22.8% with insufficient information or no case file. The prevalence of RA was 768 (95% CI 705–835) per 100,000. The incidence of RA from HUNT2 to HUNT3 was 0.48 (0.41–0.56) per 1000 per year. The prevalence of AS was 264 (228–305) per 100,000. The incidence of AS from HUNT2 to HUNT3 was 0.19 (0.15–0.24) per 1000 per year. Conclusion. Self-reported diagnoses of RA and AS are often false-positive. The prevalence and incidence of RA were comparable to reports from similar populations. The incidence of AS was higher than previously reported in a mixed population from Norway.
Elucidating reaction mechanisms on quantum computers

Significance Our work addresses the question of compelling killer applications for quantum computers. Although quantum chemistry is a strong candidate, the lack of details of how quantum computers can be used for specific applications makes it difficult to assess whether they will be able to deliver on the promises. Here, we show how quantum computers can be used to elucidate the reaction mechanism for biological nitrogen fixation in nitrogenase, by augmenting classical calculation of reaction mechanisms with reliable estimates for relative and activation energies that are beyond the reach of traditional methods. We also show that, taking into account overheads of quantum error correction and gate synthesis, a modular architecture for parallel quantum computers can perform such calculations with components of reasonable complexity. With rapid recent advances in quantum technology, we are close to the threshold of quantum devices whose computational powers can exceed those of classical supercomputers. Here, we show that a quantum computer can be used to elucidate reaction mechanisms in complex chemical systems, using the open problem of biological nitrogen fixation in nitrogenase as an example. We discuss how quantum computers can augment classical computer simulations used to probe these reaction mechanisms, to significantly increase their accuracy and enable hitherto intractable simulations. Our resource estimates show that, even when taking into account the substantial overhead of quantum error correction, and the need to compile into discrete gate sets, the necessary computations can be performed in reasonable time on small quantum computers. Our results demonstrate that quantum computers will be able to tackle important problems in chemistry without requiring exorbitant resources.
Risk indicators of edentulism, partial tooth loss and prosthetic status among black and white middle-aged and older adults.

OBJECTIVES To describe the prevalence and risk indicators of edentulism; to describe the frequencies of wearing removable dentures; to describe the prevalence and risk indicators of fixed prosthetic restorations; to test the hypothesis that fixed prosthetic restorations are most likely to have been placed in persons at lower risk for dental and periodontal diseases, and to test the hypothesis that, with dental disease, dental behaviors, dental attitudes and ability to afford crowns taken into account, blacks are less likely than whites to have received crowns. METHODS The Florida Dental Care Study is a cohort study of subjects 45 years old or older. A telephone screening interview was done as a first stage to identify 5254 subjects who met eligibility requirements and who self-reported whether they were edentulous. In a second stage, a subsample of dentate subjects was contacted after they completed their telephone screening interview. Of these, 873 subjects completed a baseline in-person interview and dental examination. RESULTS A total of 19% of first-stage subjects were edentulous. In a single multiple logistic regression, having a poorer self-rated level of general health was significantly associated with edentulism, as were being poor, older and white. Among the second-stage participants (all of whom were dentate), several prosthetic patterns were observed. For example, a total of 64% of maxillary full denture wearers reported wearing their denture all the time. Participants had also received numerous fixed prosthodontic services. The proportion of subjects with at least one crown varied widely by subject characteristics. CONCLUSIONS A substantial percentage of non-ideal frequencies of wearing removable prostheses was reported, as were prosthesis-related soreness and broken prostheses. Although we expected and observed an association between having a fixed prosthetic crown and periodontal status, dental fillings, dental attitudes and financial resources, a residual association with race suggests that blacks are much less likely to receive prosthetic crowns. The several possible reasons for this circumstance warrant further investigation.
