Cancer-Related Pain and Pain Management

Advances in treatment mean children are increasingly cared for by their parents at home, leading to a shift in responsibility from health care professionals to parents. Little is known about parents’ pain management experiences and the etiology of pain experienced by children with cancer especially when at home. A rapid review of the literature was undertaken investigating children’s cancer-related pain, with emphasis on the management of pain outside the health care setting. Electronic databases were searched and a quality assessment was conducted. Forty-two articles were included. Despite advances in pain management techniques, children with cancer regularly cite pain as the most prevalent symptom throughout the cancer trajectory. The source of pain is usually treatment side effects or painful procedures. Parents find dealing with their child’s pain distressing and demanding and may hold misconceptions about pain management. Findings indicate a need for more robust research into parental pain management leading to the development of effective pain management resources for parents.
Delusion formation and reasoning biases in those at clinical high risk for psychosis.

BACKGROUND Cognitive models propose that faulty appraisal of anomalous experiences is critical in developing psychosis, particularly delusions. A data gathering bias may be fundamental to abnormal appraisal. AIMS To examine whether there is a data gathering bias in people at high risk of developing psychosis. METHOD Individuals with an at-risk mental state (n=35) were compared with a matched group of healthy volunteers (n=23). Participants were tested using a modified version of the 'beads' reasoning task with different levels of task difficulty. RESULTS When task demands were high, the at-risk group made judgements on the basis of less information than the control group (P<0.05). Within both groups, jumping to conclusions was directly correlated with the severity of abnormal beliefs and intolerance of uncertainty (P<0.05). In the at-risk group it was also associated with impaired working memory (P<0.05), whereas in the control group poor working memory was associated with a more conservative response style (P<0.05). CONCLUSIONS People with an at-risk mental state display a jumping to conclusions reasoning style, associated with impaired working memory and intolerance of uncertainty. This may underlie a tendency to develop abnormal beliefs and a vulnerability to psychosis.
Prospective Study on Functional Results After Lung-Sparing Radical Pleurectomy in the Management of Malignant Pleural Mesothelioma

Introduction: Malignant pleural mesothelioma (MPM) can reduce lung function by entrapping lung parenchyma via a rind of tumor with or without concurrent effusion. Radical pleurectomy (RP) allows expansion of the trapped lung. The purpose of this study was to investigate changes in pulmonary function and lung perfusion in patients undergoing RP. Methods: In a prospective, nonrandomized study, all patients with histologically proven MPM were evaluated from January to December 2010 for trimodality therapy including RP as surgical procedure. Pulmonary-function tests and perfusion scans were obtained before and 2 months after RP. Primary end points were pulmonary function (forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1]) and ipsilateral lung perfusion. Results: Sixteen out of 25 consecutive patients (age 68.8±8.9 years) were enrolled in the study. Macroscopic complete resection could be achieved in 13 patients (81.3%). Diaphragm resection was necessary in 5 patients. Significant postsurgical improvement of pulmonary function at 2 months was observed for FVC and FEV1 (both absolute and percentage of predicted values) and ipsilateral perfusion (p < 0.001). Avoidance of diaphragm resection was associated with greater increase in FVC (+34.6±17.0% versus +13.5±5.4%; p = 0.002) and FEV1 (+29.2±18.1% versus +12.1±6.4%; p = 0.015), respectively. Conclusions: Lung-sparing RP leads to significant improvement of pulmonary function and perfusion after a recovery time of 2 months. Functional results are better after preservation of the diaphragm. Preservation of physiological reserve via lung-sparing RP might allow patients with MPM to be eligible for further therapeutic options in the long term.
The adult epicardium: realizing the potential for neovascular therapy.

From the first description of its origins by the Polish-German anatomist Robert Remak in 1855, through to latter day studies into its role in establishing the coronary vasculature (reviewed in1), the embryological epicardium (outermost mesothelial epithelial layer that envelops the developing heart) has intrigued embryologists, cell biologists, and cardiologists alike. The adult epicardium, on the other hand, has been consigned to the overall view that the mature mammalian heart is a terminally differentiated postmitotic organ in which the major structural cell types survive a life time without support from either new vascular or myocardial cells. However, recently the quiescent nature of the adult epicardium has been contested. After appropriate stimulation (by the actin monomer binding protein Thymosin β4) adult epicardium-derived cells (EPDCs) were shown to have the capacity to proliferate, migrate, and differentiate ex vivo into vascular …
Decrease of cone opsin mRNA in experimental ocular hypertension.

PURPOSE This study was designed to test the hypothesis that photoreceptors are adversely affected in glaucoma. As a measure of this effect, we examined the levels of rod opsin, and red/green and blue cone opsin mRNAs in monkeys with experimental ocular hypertension and glaucoma and in human eyes from donors with diagnosed glaucoma. METHODS Experimental ocular hypertension was induced in one eye of 19 cynomolgous and 2 rhesus monkeys by laser ablation of the trabecular meshwork. In 15 monkeys, the elevated IOP was reduced by trabeculectomy. When the animals had experienced prolonged elevations of IOP (128 to 260 days), they were killed and the eyes enucleated. Fresh retinal tissue from the macula, inferotemporal retina (mid-peripheral), and far peripheral regions were harvested from some animals using a 3 mm trephine. The remaining retinas from these monkeys, and whole retinas from other animals were fixed. RNA isolated from each trephined sample was used for RNase Protection Analysis or real time PCR analysis to quantify opsin mRNA levels from different photoreceptor cell types. Fixed tissue was used for in situ hybridization studies. Human donor eyes (7 glaucoma and 4 control) were obtained from eye banks. All human specimens were used for in situ hybridization studies. RESULTS Quantitative mRNA analysis and in situ hybridization studies both showed a reduction in the expression of red/green and blue cone opsin mRNAs in 6 monkey eyes with chronic ocular hypertension, relative to the contralateral eye. No loss of rod opsin mRNA was observed. The principal reduction occurred in cells of the mid-peripheral retina, a region of retina that often shows early and progressive damage in humans with glaucoma. In monkeys with ocular hypertension followed by trabeculectomy, there was a similar decrease in cone opsin mRNAs, but only in six out of fifteen (40%) of the monkeys. The decrease in these animals was correlated with a significantly elevated IOP at some time during the 2 weeks prior to euthanization and not with the extent of glaucomatous damage. Of the 7 human eyes with diagnosed glaucoma that were examined, 5 showed a decrease of cone opsin mRNA in the mid-peripheral retina, whereas none of the 4 normal eyes examined showed a decrease. CONCLUSIONS Ocular hypertension leading to glaucoma also affects the outer retina, particularly the cone photoreceptors. We speculate that these cells become stressed leading to a disruption in the expression of normal genes, such as that encoding opsin. There is some evidence that this effect is reversible, when IOP levels are reduced.
In vitro Efficacy of Experimental Chitosan-Containing Solutions as Anti-Erosive Agents in Enamel

The present study evaluated the effect of chitosans with different viscosities, dissolved in an AmF/SnCl2 solution, against erosion or erosion/abrasion. A total of 192 specimens were assigned to 2 × 6 groups (n = 16 specimens each): negative control, 4 chitosan solutions (groups Ch50, Ch500, Ch1000, and Ch2000, with viscosity of 50, 500, 1,000, or 2,000 mPas, respectively, 0.5% chitosan, 500 ppm F-, 800 ppm Sn2+, pH 4.4), and positive control (500 ppm F-, 800 ppm Sn2+, pH 4.3). One half of the groups was demineralized (experiment 1, E1; 10 days, 6 × 2 min/day, 0.5% citric acid, pH 2.8) and exposed to solutions (2 × 2 min/day); the other half was additionally brushed (15 s, 200 g) with non-fluoridated toothpaste before solution immersion (experiment 2, E2). Treatment effects were investigated by profilometry, energy-dispersive X-ray spectroscopy and scanning electron microscopy (SEM). In E1, all the chitosan-containing solutions reduced enamel loss by 77-80%, to the same extent as the positive control, except for Ch2000 (p ≤ 0.05), which completely inhibited tissue loss by the formation of precipitates. In E2, Ch50 and Ch500 showed best performance, with approximately 60% reduction of tissue loss compared to the negative control group (p ≤ 0.05 compared to other groups). SEM analysis showed differences between negative control and the other groups but only minor differences amongst the groups treated with active agents. In both E1 and E2, treatment with active agents resulted in surface enrichment of carbon and tin compared to negative control (p ≤ 0.001); brushing removed parts of carbon and tin (p ≤ 0.001). Chitosan shows different properties under erosive and erosive/abrasive conditions. Under erosive conditions high viscosity might be helpful, whereas lower viscosity seems to be more effective in cases of chemo-mechanical challenges.
Eye gaze cannot be ignored (but neither can arrows)

Recent studies have tried to shed light on the automaticity of attentional shifts triggered by gaze and arrows with mixed results. In the present research, we aimed at testing a strong definition of resistance to suppression for orienting of attention elicited by these two cues. In five experiments, participants were informed with 100% certainty about the future location of a target they had to react to by presentation of either a direction word at the beginning of each trial or instructions at the beginning of each block. Gaze and arrows were presented before the target as uninformative distractors irrelevant for the task. The results showed similar patterns for gaze and arrows—namely, an interference effect when the distractors were incongruent with the upcoming target location. This suggests that the orienting of attention mediated by gaze and arrows can be considered as strongly automatic.
Influence of rifampicin on drug metabolism: Differences between hexobarbital and antipyrine

Six healthy volunteers were treated with 1,200 mg of rifampicin daily for 8 days. Before and immediately afterward each received indocyanine green, hexobarbital, galactose, and antipyrine by intravenous infusion on 3 consecutive days. The plasma concentrations of the drugs were determined several times after infusion. The average elimination half‐life of hexobarbital had decreased from 407 to 171 min and its metabolie clearance had increased almost threefold. In contrast, the average elimination half‐life of antipyrine was virtually the same on both occasions (6.9 and 7.2 hr) and there was no change in metabolie clearance. In a tuberculous patient treated with rifampicin the antipyrine elimination rate was unaffected. Rifampicin did not infiuence indocyanine green clearance or galactose elimination capacity. Serum gamma glutamyl transferase was not affected but urinary D‐glucaric acid excretion was increased during rifampicin treatment. The experiment with hexobarbital was repeated after 2 weeks in all subjects; half‐lives and clearance values had returned to near control values. It appears that rifampicin is a selective inducer of oxidative drug metabolism in man.
Treatment of Disorders of Consciousness in the Veterans Health Administration Polytrauma Centers

This article describes the evolution of the emerging consciousness programs and the approach to care for veterans and active duty service members with disorders of consciousness (DOC) at the 4 polytrauma rehabilitation centers of the Veterans Health Administration. Compared to traditional rehabilitation patients, DOC patients have unique recovery patterns and rehabilitative needs, and they require an intensive medical and nursing support structure. This requires closely integrated rehabilitation and acute medical care to ensure the highest level of outcomes. Unfortunately, little information exists in the literature to establish best practices for the rehabilitation of this population. It is the authors' intentions to bridge the literature gap in regard to programmatic structure, treatment approaches for those with DOC, and support of their caregivers. This article includes descriptions of medical care protocols, review of stimulation approaches (environmental and pharmacologic) caregiver support, and monitoring of recovery patterns.
Gastrointestinal actions of glucagon‐like peptide‐1‐based therapies: glycaemic control beyond the pancreas

The gastrointestinal hormone glucagon‐like peptide‐1 (GLP‐1) lowers postprandial glucose concentrations by regulating pancreatic islet‐cell function, with stimulation of glucose‐dependent insulin and suppression of glucagon secretion. In addition to endocrine pancreatic effects, mounting evidence suggests that several gastrointestinal actions of GLP‐1 are at least as important for glucose‐lowering. GLP‐1 reduces gastric emptying rate and small bowel motility, thereby delaying glucose absorption and decreasing postprandial glucose excursions. Furthermore, it has been suggested that GLP‐1 directly stimulates hepatic glucose uptake, and suppresses hepatic glucose production, thereby adding to reduction of fasting and postprandial glucose levels. GLP‐1 receptor agonists, which mimic the effects of GLP‐1, have been developed for the treatment of type 2 diabetes. Based on their pharmacokinetic profile, GLP‐1 receptor agonists can be broadly categorized as short‐ or long‐acting, with each having unique islet‐cell and gastrointestinal effects that lower glucose levels. Short‐acting agonists predominantly lower postprandial glucose excursions, by inhibiting gastric emptying and intestinal glucose uptake, with little effect on insulin secretion. By contrast, long‐acting agonists mainly reduce fasting glucose levels, predominantly by increased insulin and reduced glucagon secretion, with potential additional direct inhibitory effects on hepatic glucose production. Understanding these pharmacokinetic and pharmacodynamic differences may allow personalized antihyperglycaemic therapy in type 2 diabetes. In addition, it may provide the rationale to explore treatment in patients with no or little residual β‐cell function.
The influence of the functional capacity on subjective well-being and quality of life of patients with silicosis

Objectives: Silicosis is a fibrosing and irreversible lung disease. In China, 9870 new silicosis cases were reported in 2010. The physical and mental status of patients with silicosis should be paid attention to. The aims of this study were to evaluate the influence of the patients’ functional capacity on subjective well-being (SWB) and quality of life (QOL), provide the scientific basis for further intervention measures, and improve their health status. Methods: We investigated 324 inpatients with silicosis during April 2011 to September 2011. The 6-minute walk test (6MWT) was the major methodology used to evaluate the functional capacity, the SF-12 (Short Form-12) to evaluate the QOL, and the MUNSH (Memorial University of Newfoundland Scale of Happiness) scale to evaluate the SWB. Results: The distance of 6MWT suggested a significant and positive correlation with SWB and QOL of patients with silicosis (P < 0.01). In China, patients with silicosis had low SWB and QOL. Conclusions: The SWB and QOL of patients with silicosis are still relatively low and their health status needs improvement. At the same time, longer distances walked by patients suggest more positive influences on their SWB and QOL. It indicates that when the 6MWT cooperates with SWB and QOL, it may be able to get more accurate evaluation results of patients’ survival status.
Relationship between hepatitis C and microalbuminuria: results from the NHANES III.

BACKGROUND Hepatitis C infection is associated with diabetes mellitus and insulin resistance and it is suggested that metabolic syndrome is common in patients with hepatitis C. Microalbuminuria is common in patients with diabetes and metabolic syndrome; however, no studies have examined the relationship between microalbuminuria and hepatitis C infection. METHODS We conducted a nested case-control study to examine the relationship between nondiabetic subjects with hepatitis C infection and microalbuminuria by using the Third National Health and Nutrition Examination Survey (NHANES III) database. Study cohort consisted of 15,336 adults from the United States who had hepatitis C antibody measured as part of the NHANES III. The prevalence of microalbuminuria and the metabolic syndrome were compared between individuals with positive hepatitis C infection antibody (N= 362) and matched controls (N= 995). Additional analyses were conducted to define the association between hepatitis C infection and microalbuminuria. RESULTS Prevalence of microalbuminuria in patients with hepatitis C infection was 12.4% and it was significantly higher than in controls (7.5%) (P= 0.001). This difference persisted even after excluding diabetics from the analyses (11.4% vs. 6.7%) (P= 0.001). However, there was no difference in the prevalence of the metabolic syndrome between two groups (19% vs. 19%) (P= 0.9). After controlling for relevant covariates, hepatitis C infection was independently associated with microalbuminuria in subjects without diabetes (odds ratio 1.99, 95% CI 1.38-2.85) (P= 0.008). Older age and African Americans were independently associated with microalbuminuria in nondiabetic hepatitis C patients. CONCLUSION Hepatitis C infection is independently associated with microalbuminuria but not the metabolic syndrome. Older age and African Americans are strongly associated with microalbuminuria in nondiabetic hepatitis C subjects. More research is needed to explore the implications of these observations.
Early Assessment of Nerve Degeneration Using the Antidromic Facial Nerve Response

Conclusion: The antidromic facial nerve response (AFNR) is recommended as a monitoring method to detect cases resulting in facial nerve degeneration within 1 week after onset in patients with Bell’s palsy and Hunt syndrome. Objectives: The purpose of this study was to establish criteria for the AFNR to predict the prognosis of Bell’s palsy and Hunt syndrome in the early stages, not exceeding 1 week after onset. Materials and Methods: 54 patients, including 40 with Bell’s palsy and 14 with Hunt syndrome, were examined in this study. All patients were tested for the AFNR within 1 week after onset of paralysis and AFNR waveforms were analyzed. Four AFNR parameters, the total (peak-to-peak) amplitude (T-amp), the amplitudes of the positive wave (P-amp) and the negative wave (N-amp), and the N-amp/T-amp (N/T) ratio, were compared with the outcomes of facial paralysis. Results:In most patients with poor outcomes, T-amp was <4 µV and N-amp was <2 µV. The mean value of the N/T ratio in patients with a poor outcome fell to <0.4 after the 3rd day from onset, while that in patients with a good outcome was stable between 0.4 and 0.6 during the first week.
Long‐term follow‐up after cure of Helicobacter pylori infection with 4 days of quadruple therapy

Background: We have shown that 4 days of quadruple therapy after omeprazole pre‐treatment is an effective therapy for curing H. pylori infection. In this study we investigated whether this regimen would maintain the high cure rate during long‐term follow‐up. Some recent studies have reported high recurrence rates after apparent cure. Apparently not all methods to test for cure have sufficient sensitivity to pick up small numbers of residual bacteria. This study also served to investigate whether our methods to test for cure 5–6 weeks post‐treatment were reliable.
High‐field magnetic birefringence study of the structure of rodlike phages Pf1 and fd in solution

The magnetic orientation of the rodlike bacterial viruses Pf1 and fd in dilute aqueous solution was detected by high‐resolution birefringence measurements. Partial alignment takes place parallel to the magnetic field chiefly due to the diagmagnetic anisotropy of the highly ordered α‐helices in the coat protein. It follows from the analysis of the experimental diamagnetic anisotropy that in both phages the α‐helices and aromatic amino acids are oriented relatively parallel to the phage axis. In Pf1 these become, on average, more nearly parallel as the temperature is reduced from about 25 to 5°C. These results demonstrate that high‐resolution magnetically induced birefringence measurements can be used to investigate some general structural features of complicated biological particles in solution.
Effect of partial recording protocols on estimates of prevalence of periodontal disease.

BACKGROUND The aim of this study was to assess the degree of underreporting in the estimates of prevalence of periodontal attachment loss due to different partial recording protocols (PRP) in epidemiological studies, and to derive a correction factor to adjust for this bias. METHODS The study sample included 1,460 dentate persons 14 to 103 years old who were examined clinically to assess the clinical attachment loss at six sites per tooth. Seven PRP based on full-mouth or half-mouth designs were assessed, and the bias and sensitivity in the assessment of attachment loss prevalence for these protocols were assessed. RESULTS All partial protocols underestimated the prevalence of attachment loss. Bias estimates for any full-mouth PRP were smaller than those for the corresponding site-combination PRP for the half-mouth design. The PRP using the mesio-buccal (MB), mid-buccal (B), and disto-lingual (DL) sites of teeth in all four quadrants showed the smallest bias and highest sensitivity of prevalence estimates among the seven PRP evaluated, uniformly across the range of attachment loss severity level. The three site PRP incorporating the DL site produced less bias than the three site PRP including the disto-buccal (DB) site. There was a 3% to 12% gain in sensitivity for 2 to 5 mm attachment loss thresholds for the three site half-mouth PRP compared with the two site MB, B half-mouth PRP. CONCLUSIONS The bias in the assessment of attachment loss is influenced by the partial recording design and the type and number of sites assessed, and is also influenced by the severity of attachment loss in the study population. These factors should be considered when selecting a partial recording method in large surveys. Furthermore, inflation factors designed to adjust for the bias due to the use of partial systems should be calculated and reported so that comparisons of results with other surveys are more meaningful.
