Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool Adverse Events Profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman’s correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1 mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4–8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the WHO report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects. Additional investigations regarding phenobarbital side effects in routine care in low income settings is warranted. PMID:25219354

Introduction Despite evidence of the efficacy of adjuvant endocrine therapy (AET) in reducing the risk of recurrence and mortality after treatment for primary breast cancer, adherence to AET is suboptimal. This study aimed to explore factors that influence adherence and nonadherence to AET following breast cancer to inform the development of supportive interventions. Methods Interviews were conducted with 32 women who had been prescribed AET, 2–4 years following their diagnosis of breast cancer. Both adherers (n=19) and nonadherers (n=13) were recruited. The analysis was conducted using the Framework approach. Results Factors associated with adherence were as follows: managing side effects including information and advice on side effects and taking control of side effects, supportive relationships, and personal influences. Factors associated with nonadherence were as follows: burden of side effects, feeling unsupported, concerns about long-term AET use, regaining normality, including valuing the quality of life over length of life, and risk perception. Conclusion Provision of timely information to prepare women for the potential side effects of AET and education on medication management strategies are needed, including provision of timely and accurate information on the efficacy of AET in reducing breast cancer recurrence and on potential side effects and ways to manage these should they arise. Trust in the doctor–patient relationship and clear patient pathways for bothersome side effects and concerns with AET are important. Training and education on AET for GPs should be considered alongside novel care pathways such as primary care nurse cancer care review and community pharmacist follow-up. PMID:29497284

The burden of major depressive disorder includes suffering due to symptom severity, functional impairment, and quality of life deficits. The aim of this study was to compare the differences between electroconvulsive therapy and pharmacotherapy in reducing such burdens. This was a pooled analysis study including 2 open-label trials for major depressive disorder inpatients receiving either standard bitemporal and modified electroconvulsive therapy with a maximum of 12 sessions or 20 mg/d of fluoxetine for 6 weeks. Symptom severity, functioning, and quality of life were assessed using the 17-item Hamilton Rating Scale for Depression, the Modified Work and Social Adjustment Scale, and SF-36. Side effects following treatment, including subjective memory impairment, nausea/vomiting, and headache, were recorded. The differences between these 2 groups in 17-item Hamilton Rating Scale for Depression, Modified Work and Social Adjustment Scale, quality of life, side effects, and time to response (at least a 50% reduction of 17-item Hamilton Rating Scale for Depression) and remission (17-item Hamilton Rating Scale for Depression ≤7) following treatment were analyzed. Electroconvulsive therapy (n=116) showed a significantly greater reduction in 17-item Hamilton Rating Scale for Depression, Modified Work and Social Adjustment Scale, and quality of life deficits and had significantly shorter time to response/remission than fluoxetine (n=126). However, the electroconvulsive therapy group was more likely to experience subjective memory impairment and headache. Compared with fluoxetine, electroconvulsive therapy was more effective in alleviating the burden of major depressive disorder and had a substantially increased speed of response/remission in the acute phase. Increased education and information about electroconvulsive therapy for clinicians, patients, and their families and the general public is warranted. © The Author(s) 2017.

Almost 2.8 million men in the U.S. are living with prostate cancer (PC), accounting for 40% of all male cancer survivors. Men diagnosed with prostate cancer may experience chronic and debilitating treatment side effects, including sexual and urinary dysfunction, pain and fatigue. Side effects can be stressful and can also lead to poor psychosocial functioning. Prior trials reveal that group-based cognitive behavioral stress and self-management (CBSM) is effective in reducing stress and mitigating some of these symptoms, yet little is known about the effects of culturally-translated CBSM among Spanish-speaking men with PC. This manuscript describes the rationale and study design of a multi-site, randomized controlled trial to determine whether participation in a culturally adapted cognitive behavioral stress management (C-CBSM) intervention leads to significantly greater reductions in symptom burden and improvements in health-related quality of life relative to participation in a non-culturally adapted cognitive behavioral stress management (CBSM) intervention. Participants (N = 260) will be Spanish-speaking Hispanic/Latino men randomized to the standard, non-culturally adapted CBSM intervention (e.g., cognitive behavioral strategies, stress management, and health maintenance) or the culturally adapted C-CBSM intervention (e.g., content adapted to be compatible with Hispanic/Latino cultural patterns and belief systems, meanings, values and social context) for 10 weeks. Primary outcomes (i.e., disease-specific symptom burden and health-related quality of life) will be assessed across time. We hypothesize that a culturally adapted C-CBSM intervention will be more efficacious in reducing symptom burden and improving health-related quality of life among Hispanic/Latino men when compared to a non-culturally adapted CBSM intervention.

For many years anticoagulant rodenticides have been used in vole control campaigns, in spite of the proven risk of secondary poisoning of non-target predators and scavengers. In this paper we analyse for the first time great bustard exposure and intoxication by anticoagulant rodenticides in Spain, based on residues found in the livers of 71 bustard carcasses collected during 1991-2010. Ten individuals contained chlorophacinone and one flocoumafen. Chlorophacinone level was significantly correlated with the pathogen and parasite burden of intoxicated birds. Moreover, through the last 12 years the annual number of great bustards that present chlorophacinone in liver collected in our study areas was correlated with vole peaks at a nearby area, suggesting that the ingestion of rodenticide was proportional to the amounts spread in the fields. We conclude that rodenticide consumption is a regular event among great bustards when baited cereal is spread on fields, and that this may cause chronic weakening of intoxicated individuals, possibly affecting their survival. Future rodent control actions should consider these negative side effects on non target granivorous steppe and farmland species, particularly when they are globally threatened. Copyright © 2011.

Helminth-free dogs and cats were experimentally infected with protoscoleces of Echinococcus multilocularis and used in controlled trials for efficacy evaluation of the cestodicide epsiprantel. In two separate trials each 4 dogs were treated at day 20 post infection (p.i.) with average oral dosages of 5.1 (4.9-5.3) and 5.4 (5.2-5.8) mg/kg body weight (b.w.) epsiprantel, respectively, and necropsied at day 24 p.i. Among each 4 dogs of the two untreated control groups all animals were infected and had high intestinal worm burdens with averages of 33.575 and 100.725 E. multilocularis specimens per animal (individual worm burdens in group Ib 59,500-149,800, group IIb 20,500-43,200); in the two groups of treated dogs the average worm burdens were reduced by 99.6 and 99.9%. Among 8 treated dogs 4 were helminth-free, the other 4 had residual worm burdens (10-70 in 3 dogs, 1480 in 1 dog). In each 5 cats single oral treatments with average doses of 2.7 (2.7-2.8) and 5.5 (5.5-5.5) mg/kg b.w. epsiprantel were 100% effective against E. multilocularis 20 days p.i. and eliminated the worm burdens from all 10 animals. In the untreated group of 5 cats the average worm burden was 2864 per animal (individual worm burdens 20-6830). Side effects of the drug treatment were not observed. The results of the study show that in single therapeutic dosages recommended by the producer (dogs 5.5 mg, cats 2.75 mg/kg b.w.) epsiprantel eliminates E. multilocularis to over 99% or completely, but residual worm burdens may persist in some animals.

Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD-7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted β = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (β = 0.08, p = 0.306). Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. Trial Number NCT01072344 at ClinicalTrials.gov. Copyright © 2016 Elsevier Ltd. All rights reserved.

Cytochrome P450 enzymes are important in the metabolism of antidepressants. The highly polymorphic nature of these enzymes has been linked to variability in antidepressant metabolism rates, leading to hope regarding the use of P450 genotyping to guide treatment. However, evidence that P450 genotypic differences underlie the variation in treatment outcomes is inconclusive. We explored the links between both P450 genotype and serum concentrations of antidepressant with antidepressant side effects, using data from the Genome-Based Therapeutic Drugs for Depression Project (GENDEP), which is a large (n = 868), pharmacogenetic study of depressed individuals treated with escitalopram or nortriptyline. Patients were genotyped for the enzymes CYP2C19 and CYP2D6, and serum concentrations of both antidepressant and primary metabolite were measured after 8 weeks of treatment. Side effects were assessed weekly. We investigated associations between P450 genotypes, serum concentrations of antidepressants and side effects, as well as the relationship between P450 genotype and study discontinuation. P450 genotype did not predict total side effect burden (nortriptyline: n = 251, p = 0.5638, β = -0.133, standard error (SE) = 0.229; escitalopram: n = 340, p = 0.9627, β = -0.004, SE = 0.085), study discontinuation (nortriptyline n = 284, hazard ratio (HR) = 1.300, p = 0.174; escitalopram n = 376, HR = 0.870, p = 0.118) or specific side effects. Serum concentrations of antidepressant were only related to a minority of the specific side effects measured: dry mouth, dizziness and diarrhoea. In this sample where antidepressant dosage is titrated using clinical judgement, P450 genotypes do not explain differences between patients in side effects with antidepressants. Serum drug concentrations appear to only explain variability in the occurrence of a minority of specific side effects.

Considering the recent popularity of bodybuilding and the apparent spread of anabolic androgenic steroid (AAS) use amongst bodybuilding enthusiasts in Kuwait, there is a relative lack of scientific investigation into the use, knowledge and attitudes towards AAS amongst the population at risk of abusing it. Therefore, this study aims to investigate the frequency, knowledge, attitudes and practice of AAS use amongst male fitness centre attendees in Kuwait. A cross sectional survey utilizing a self-administered questionnaire was used. Information on demographics as well as knowledge and attitude about and towards the use of AAS was included in the questionnaire. Ten fitness centres in Kuwait were randomly selected and questionnaires were distributed to all individuals leaving each centre on randomly selected days and periods of time for each centre. Overall n = 400 questionnaires were distributed. A total of n = 194 questionnaires were returned completed (~49%). Of the responders, 22.7% used AAS. The 19-25 age group had the highest occurrence (46.8%) of first-time AAS use. In contrast with non-users, most (70.5%) of AAS users believed that having an optimally muscular body can only be achieved by using AAS, and a small minority (6.8%) believed that AAS usage would have significant harms to health. Only 18.2% of AAS users had appropriate knowledge regarding the side effects of AAS. Non-users were as much uninformed as AAS users regarding the side effects of AAS. The usage of AAS is high amongst male gym users in Kuwait and is likely to present an additional burden to the health service. An effective initiative to minimize the burden of AAS abuse should focus on changing the attitudes towards AAS rather than spreading awareness of their side effects.

Symptoms guide disease management, and patients frequently report HIV-related symptoms, but HIV symptom patterns reported by patients have not been described in the era of improved antiretroviral treatment. The objectives of our study were to investigate the prevalence and burden of symptoms in people living with HIV and attending an outpatient clinic. The prevalence, burden, and bothersomeness of symptoms reported by patients in routine clinic visits during 2011 were assessed using the 20-item HIV Symptom Index. Principal component analysis was used to identify symptom clusters and relationships between groups using appropriate statistic techniques. Two main clusters were identified. The most prevalent and bothersome symptoms were muscle aches/joint pain, fatigue, and poor sleep. A third of patients had seven or more symptoms, including the most burdensome symptoms. Even with improved antiretroviral drug side-effect profiles, symptom prevalence and burden, independent of HIV viral load and CD4+ T cell count, are high. Published by Elsevier Inc.

The present study aimed to investigate the perceived level of burden of care and its correlates in family members of schizophrenia patients. The study included 239 schizophrenic patients that were followed-up at the psychiatric outpatient clinics of Izmir Ataturk Education and Research Hospital, and Celal Bayar University Medical School, and 239 of their primary caregivers. Patients were assessed using the Positive and Negative Syndrome Scale (PANNS), Global Assessment of Functioning Scale (GAF), Social Functioning Scale (SFS), Brief Cognitive State Examination (BCE), and UKU Side Effect Rating Scale. Their primary caregivers were assessed using the Perceived Family Burden Scale (PFBS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Caregiver PFBS scores ere correlated with male patients, female caregivers, inadequate social support, economic difficulty, the presence of chronic physical disorder in the caregivers, patient violence toward the caregivers, total duration of illness, the number of patient hospitalizations, PANNS total and subscale scores, and SFS, BDI, and BAI scores. Perceived burden of care was predicted by the severity of the patients' positive symptoms, SFS independence/competence and interpersonal functioning subscale scores, and caregivers' anxiety and depression levels. In order to decrease the burden of care in schizophrenia we recommend effective management of patient symptoms, enhancement of patient social functioning, interventions that target caregivers with high levels anxiety and depression, and social support provided by healthcare professionals.

Because some cryptogenic strokes may result from large-artery atherosclerosis that goes unrecognized as it causes <50% luminal stenosis, we compared the prevalence of nonstenosing intracranial atherosclerotic plaques ipsilateral to cryptogenic cerebral infarcts versus the unaffected side using imaging biomarkers of calcium burden. In a prospective stroke registry, we identified patients with cerebral infarction limited to the territory of one internal carotid artery (ICA). We included patients with stroke of undetermined etiology and, as controls, patients with cardioembolic stroke. We used noncontrast computed tomography to measure calcification in both intracranial ICAs, including qualitative calcium scoring and quantitative scoring utilizing the Agatston-Janowitz (AJ) calcium scoring. Within subjects, the Wilcoxon signed-rank sum test for nonparametric paired data was used to compare the calcium burden in the ICA upstream of the infarction versus the ICA on the unaffected side. We obtained 440 calcium measures from 110 ICAs in 55 patients. Among 34 patients with stroke of undetermined etiology, we found greater calcium in the ICA ipsilateral to the infarction (mean Modified Woodcock Visual Scale score, 6.7 ± 4.6) compared with the contralateral side (5.4 ± 4.1) (P = .005). Among 21 patients with cardioembolic stroke, we found no difference in calcium burden ipsilateral to the infarction (6.7 ± 5.9) versus the contralateral side (7.3 ± 6.3) (P = .13). The results were similar using quantitative calcium measurements, including the AJ calcium scores. In patients with strokes of undetermined etiology, the burden of calcified intracranial large-artery plaque was associated with downstream cerebral infarction.

Electroconvulsive therapy (ECT) has demonstrated efficacy in treating core symptoms of Parkinson's disease (PD); however, widespread use of ECT in PD has been limited due to concern over cognitive burden. We investigated the use of a newer ECT technology known to have fewer cognitive side effects (right unilateral [RUL] ultra-brief pulse [UBP]) for the treatment of medically refractory psychiatric dysfunction in PD. This open-label pilot study included 6 patients who were assessed in the motoric, cognitive, and neuropsychiatric domains prior to and after RUL UBP ECT. Primary endpoints were changes in total score on the HAM-D-17 and GDS-30 rating scales. Patients were found to improve in motoric and psychiatric domains following RUL UBP ECT without cognitive side effects, both immediately following ECT and at 1-month follow-up. This study demonstrates that RUL UBP ECT is safe, feasible, and potentially efficacious in treating multiple domains of PD, including motor and mood, without clear cognitive side effects. © 2016 John Wiley & Sons A/S.

Chui, Ping Lei; Abdullah, Khatijah Lim; Wong, Li Ping; Taib, Nur Aishah

Complementary and alternative medicine (CAM) is commonly used for cancer- and chemotherapy-related symptoms. Nurses are likely to encounter many CAM users in their practice. The aims of this study were to assess CAM use and examine the symptom burden of CAM and non-CAM users among patients with breast cancer who are undergoing chemotherapy. A CAM use questionnaire and the Side-Effect Burden Scale were administered to 546 patients. Complementary and alternative medicine use was categorized as mind-body practices (MBPs), natural products (NPs), or traditional medicine (TM). We identified 386 CAM users (70.7%) in this study. The CAM users reported a higher marginal mean total symptom burden score (40.39 ± 2.6) than non-CAM users (36.93 ± 3.21), although this difference was not statistically significant (P = .09). Triple-modality (MBP-NP-TM) CAM users had a significantly higher marginal mean total symptom burden score (47.44 ± 4.12) than single-modality (MBP) users (34.09 ± 4.43). The risk of having a high total symptom burden score was 12.9-fold higher among the MBP-NP-TM users than among the MBP users. Complementary and alternative medicine use is common among Malaysian patients who are undergoing chemotherapy for breast cancer. However, CAM and non-CAM users reported similar symptom burdens, although single-modality use of MBP is likely associated with a lower symptom burden. Nurses should keep abreast of current developments and trends in CAM use. Understanding CAM use and the related symptom burden will allow nurses to initiate open discussion and guide their patients in seeking additional information or referrals for a particular therapy.

Evidence-informed frameworks for cost-effective cancer prevention and management are essential for delivering equitable outcomes and tackling the growing burden of cancer in all resource settings. Evidence can help address the demand side pressures (ie, pressures exerted by people who need care) faced by economies with high, middle, and low incomes, particularly in the context of transitioning towards (or sustaining) universal health-care coverage. Strong systems, as opposed to technology-based solutions, can drive the development and implementation of evidence-informed frameworks for prevention and management of cancer in an equitable and affordable way. For this to succeed, different stakeholders-including national governments, global donors, the commercial sector, and service delivery institutions-must work together to address the growing burden of cancer across economies of low, middle, and high income.

Flupirtine, a functional NMDA antagonist, does not seem to be efficacious in the treatment of tinnitus. The purpose of this study was to investigate whether flupirtine has any beneficial effect on tinnitus perception. Twenty-four patients were selected (6 female and 18 male patients) with continuous subjective tinnitus. Eight patients suffered left-sided tinnitus, 4 right-sided tinnitus and 12 bilateral tinnitus. We assessed the burden of the tinnitus by loudness visual analogue scale (VAS) and tinnitus questionnaire (TQ) according to Hallam et al., and Hiller and Goebel. All patients were treated with a 2 x 100 mg daily dosage of oral flupirtine for 3 weeks in an open prospective design. There was no statistical effect on VAS and TQ of the treatment with flupirtine. Only one patient (4.2%) experienced a positive effect on the tinnitus but discontinued the treatment because of amnesia and concentration disorders.

Antidepressants have reduced the symptom burden for many Major Depressive Disorder (MDD) patients, but drug-related side effects and treatment resistance continue to present major challenges. Pharmacogenomics represents one approach to enhance antidepressant efficacy and avoid adverse reactions, but concerns remain with regard to the overall "value equation," and several barriers must be overcome to achieve the full potential of MDD pharmacogenomics. © 2018 American Society for Clinical Pharmacology and Therapeutics.

The aim of this study was to investigate the relationship between injuries, side effects of antiepileptic drugs (AEDs) and depression. Data from a consecutive sample of adult patients with epilepsy attending the outpatient clinics at St George's University Hospital in London were included. All patients were asked if they had had any injury since the last clinic appointment and completed the Liverpool Adverse Event Profile (LAEP) and Neurological Disorders Depression Inventory for Epilepsy. Among 407 patients (243 females, mean age 43.1 years), 71 (17.4%) reported injuries since the last appointment. A two-step cluster analysis revealed two clusters with the major cluster (53.5% of the injured group) showing a total score for LAEP ≥45, a positive Neurological Disorders Depression Inventory for Epilepsy screening and presence of AED polytherapy. A total score for LAEP ≥45 was the most important predictor. Antiepileptic drug treatment should be reviewed in patients reporting injuries in order to evaluate the potential contribution and burden of AED side effects. © 2017 EAN.

Dual-opioid therapy: changing the paradigm. Introduction.

PubMed

Nicholson, Bruce D

2012-03-01

Morphine sulfate and oxycodone hydrochloride are commonly used for pain management because of their pharmacologic profile, pharmacokinetics, and analgesic potency. However, opioids are associated with a significant adverse event (AE) burden that limits their use in both the acute and the chronic pain settings. Co-administration of opioids demonstrated synergistic analgesia and reduced side effects. Thus, dual-opioid therapy has the potential to enhance the positive analgesic benefits of opioids, while limiting the burden of opioid-related AEs. This symposium proceedings was based on presentations at the 13th World Congress on Pain in August 2010. This program will review the rationale for dual-opioid therapy based on preclinical findings and data from clinical studies showing the efficacy and tolerability profile of a dual-opioid formulation when used to treat acute postoperative pain.

The aim of this study was to examine how patients recall symptoms at a delayed self-report. Accurate insight into toxicity symptoms during chemotherapy is essential so that nurses and doctors can assess therapeutic tolerance and adjust supportive care accordingly. A non-experimental, longitudinal design was employed. Using the Therapy-Related Symptoms Checklist (TRSC), respondents (n = 142) reported their initial symptoms during the first 7 days of the chemotherapy cycle at two different times: (1) each day of the first seven days after the chemotherapy administration (immediate self-report), and (2) at their next hospital visit for chemotherapy (delayed self-report). We compared the number and severity of symptoms and side effects reported in the immediate and delayed self-reports. Respondents reported significantly fewer symptoms and fewer severe symptoms in the delayed self-report. For 22 out of 25 symptoms the delayed-reported grade was significantly lower than the immediate-reported maximum grade. Compared to the immediate-reported median grade, significant differences occurred in only 10 out of the 25 symptoms. In all cases, except fatigue, the delayed-reported grade was significantly higher than the immediate-reported median grade. This study indicates that delayed self-report of chemotherapy side effects is not an appropriate measure of actual symptoms and side effects experienced by patients. Delayed self-report gives a weaker insight into actual symptom burden. Fatigue is at particular risk to be minimized at the delayed self-report. Therefore it is recommended to assess chemotherapy-related symptoms and side effects by means of immediate self-report. Copyright © 2010 Elsevier Ltd. All rights reserved.

Side effects, or the adverse effects of drugs, contain important clinical phenotypic information that may be useful in predicting novel or unknown targets of a drug. It has been suggested that drugs with similar side-effect profiles may share common targets. The diagnostic class, Major Depressive Disorder, is increasingly viewed as being comprised of multiple depression subtypes with different biological root causes. One 'type' of depression generating substantial interest today focuses on patients with high levels of inflammatory burden, indicated by elevated levels of C-reactive proteins (CRP) and pro-inflammatory cytokines such as interleukin 6 (IL-6). It has been suggested that drugs targeting the immune system may have beneficial effect on this subtype of depressed patients, and several studies are underway to test this hypothesis directly. However, patients have been treated with both anti-inflammatory and antidepressant compounds for decades. It may be possible to exploit similarities in clinical readouts to better understand the antidepressant effects of immune-related drugs. Here we explore the space of approved drugs by comparing the drug side effect profiles of known antidepressants and drugs targeting the immune system, and further examine the findings by comparing the human cell line expression profiles induced by them with those induced by antidepressants. We found 7 immune-modulators and 14 anti-inflammatory drugs sharing significant side effect profile similarities with antidepressants. Five of the 7 immune modulators share most similar side effect profiles with antidepressants that modulate dopamine release and/or uptake. In addition, the immunosuppressant rapamycin and the glucocorticoid alclometasone induces transcriptional changes similar to multiple antidepressants. These findings suggest that some antidepressants and some immune-related drugs may affect common molecular pathways. Our findings support the idea that certain medications aimed at the immune system may be helpful in relieving depressive symptoms, and suggest that it may be of value to test immune-modulators for antidepressant-like activity in future proof-of-concept studies.

Malignant tumors are considered “unresectable” if they are adhere to vital structures or the surgery would cause irreversible damages to the patients. Though a variety of cytotoxic drugs and radiation therapies are currently available in clinical practice to treat such tumor masses, these therapeutic modalities are always associated with substantial side effects. Here, we report an injectable nanoparticle-based internal radiation source that potentially offers more efficacious treatment of unresectable solid tumors without significant adverse side effects. Using a highly efficient incorporation procedure, palladium-103, a brachytherapy radioisotope in clinical practice, was coated to monodispersed hollow gold nanoparticles with a diameter about 120 nm, to form 103Pd@Au nanoseeds. The therapeutic efficacy of 103Pd@Au nanoseeds were assessed when intratumorally injected into a prostate cancer xenograft model. Five weeks after a single-dose treatment, a significant tumor burden reduction (>80%) was observed without noticeable side effects on the liver, spleen and other organs. Impressively, >95% nanoseeds were retained inside the tumors as monitored by Single Photon Emission Computed Tomography (SPECT) with the gamma emissions of 103Pd. These findings show that this nanoseed-based brachytherapy has the potential to provide a theranostic solution to unresectable solid tumors.

Chemotherapy-Induced Peripheral Neuropathy: A Current Review

2017-01-01

Chemotherapy-induced peripheral neuropathy (CIPN) is a common dose-limiting side effect experienced by patients receiving treatment for cancer. Approximately 30–40% of patients treated with neurotoxic chemotherapy will develop CIPN and there is considerable variability in its severity between patients. It is often sensory-predominant with pain and can lead to long-term morbidity in survivors. The prevalence and burden of CIPN late effects will likely increase as cancer survival rates continue to improve. In this review, we discuss the approach to peripheral neuropathy in patients with cancer and address the clinical phenotypes and pathomechanisms of specific neurotoxic chemotherapeutic agents.

The performance of child restraint systems (CRS) in side impact motor vehicle crashes has been under study due to the injury and fatality burden of these events. Although previous research has quantified injury risk or described injured body regions, safety advances require an understanding of injury causation. Therefore, the objective was to delineate injury causation scenarios for CRS-restrained children in side impacts and document probable contact points in the vehicle interior. Two in-depth crash investigation databases, the Crash Injury Research and Engineering Network and the Partners for Child Passenger Safety Study, were queried for rear-seated, CRS-restrained children in side impact crashes who sustained Abbreviated Injury Scale 2+ injury. These cases were reviewed by a multidisciplinary team of physicians and engineers to describe injury patterns, injury causation, and vehicle components that contributed to the injuries. Forty-one occupants (average age, 2.6 years) met the inclusion criteria. Twenty-four were near side to the crash, 7 were far side, and 10 were center seated. The most common injuries were to the skull and brain with an increasing proportion of skull fracture as age increased. Head and spine injuries without evidence of head contact were rare but present. All thoracic injuries were lung contusions and no rib fractures occurred. Near-side head and face contacts points were along the rear vertical plane of the window and the horizontal plane of the window sill. Head and face contact points for center- and far-side occupants were along the edges of the front seat back and front seat head restraint. Head injuries are the target for injury prevention for children in CRS in side impact crashes. Most of these injuries are due to the contact; for near-side occupants, contact with the CRS structure and the door interior, for far- or center-seated occupants, contact with the front seat back. These data are useful in developing both educational and technological interventions to reduce the burden of injury to these children.

Low-level laser/light therapy for androgenetic alopecia.

Androgenetic alopecia (AGA) is a persistent and pervasive condition that affects men worldwide. Some common treatment options for AGA include hair prosthetics, oral and topical medications, and surgical hair restoration (SHR). Pharmaceutical and SHR treatments are associated with limitations including adverse side effects and significant financial burden. Low-level laser or light (LLL) devices offer alternative treatment options that are not typically associated with adverse side effects or significant costs. There are clinic- and home-based LLL devices. One home-based laser comb device has set a standard for others; however, this device requires time devoted to carefully moving the comb through the hair to allow laser penetration to the scalp. A novel helmet-like LLL device for hair growth has proven effective in preliminary trials and allows for hands-free use. Regardless, there are few clinical trials that have been conducted regarding LLL devices for AGA and results are mixed. Further research is required to establish the true efficacy of these devices for hair growth in comparison to existing alternative therapies.

The burden of allergic rhinitis.

PubMed

Nathan, Robert A

2007-01-01

Although formerly regarded as a nuisance disease, allergic rhinitis (AR) has a considerable effect on quality of life and can have significant consequences if left untreated. The total burden of this disease lies not only in impaired physical and social functioning but also in a financial burden made greater when considering evidence that AR is a possible causal factor in comorbid diseases such as asthma or sinusitis. Compared with matched controls, patients with AR have an approximate twofold increase in medication costs and 1.8-fold the number of visits to health practitioners. Hidden direct costs include the treatment of comorbid asthma, chronic sinusitis, otitis media, upper respiratory infection, and nasal polyposis. Nasal congestion, the most prominent symptom in AR, is associated with sleep-disordered breathing, a condition that can have a profound effect on mental health, including increased psychiatric disorders, depression, anxiety, and alcohol abuse. Furthermore, sleep-disordered breathing in childhood and adolescence is associated with increased disorders of learning performance, behavior, and attention. In the United States, AR results in 3.5 million lost workdays and 2 million lost schooldays annually. Patients struggle to alleviate their misery, frequently self-adjusting their treatment regimen of over-the-counter and prescription medications because of lack of efficacy, deterioration of efficacy, lack of 24-hour relief, and bothersome side effects. Ironically, health care providers overestimate patient satisfaction with therapy. Therefore, improvement in patient-practitioner communication may enhance patient adherence with prescribed regimens.

Rheumatoid arthritis (RA) is a predominant inflammatory autoimmune disorder. The incidence and prevalence of RA is increasing with considerable morbidity and mortality worldwide. The pathophysiology of RA has become clearer due to many significant research outputs during the last two decades. Many inflammatory cytokines involved in RA pathophysiology and the presence of autoantibodies are being used as potential biomarkers via the use of effective diagnostic techniques for the early diagnosis of RA. Currently, several disease-modifying anti-rheumatic drugs are being prescribed targeting RA pathophysiology, which have shown significant contributions in improving the disease outcomes. Even though innovations in treatment strategies and monitoring are helping the patients to achieve early and sustained clinical and radiographic remission, the high cost of drugs and limited health care budgets are restricting the easy access of RA treatment. Both direct and indirect high cost of treatment are creating economic burden for the patients and affecting their quality of life. The aim of this review is to describe the updated concept of RA pathophysiology and highlight current diagnostic tools used for the early detection as well as prognosis - targeting several biomarkers of RA. Additionally, we explored the updated treatment options with side effects besides discussing the global economic burden.

Stroke is a chronic condition that necessitates multidimensional and overwhelming care. The caregivers of stroke patients are faced with various stressors that can threaten different aspects of their health, especially their mental health. Spiritual attitude and being spiritually oriented contribute significantly to mental health and can be used as a strategy for adapting to the stressful events that are part of the role of caregiving. This study was therefore conducted to investigate the relationship between the spiritual attitude of the family caregivers of older patients with stroke and their burden. This descriptive cross-sectional study was conducted in 2016. The study population consisted of all the family caregivers of older patients with stroke presenting to health care centers and nursing service companies of Gilan Province in Iran. The participants were selected through convenience sampling and consisted of 407 participants. Data were collected using the Spiritual Attitude Scale and the Caregiver Burden Inventory and were then analyzed in SPSS-18 using Pearson's correlation coefficient at a significance level of 0.05. The results showed that 88.9% of the caregivers were females. The mean age of the participants was 38.3±8.8 years. The duration of caregiving was <5 years in 84.4% of the participants, while its mean was 4.2±2.5 years. The mean score of spiritual attitude was 108.77±6.20. The majority of the participants (49.3%) had moderate and relatively favorable spiritual attitude (a score of 72-120), 27.8% had high or favorable spiritual attitude; 8.7% had mild burden, 54.4% had moderate burden and 37% had favorable burden. The mean score of burden was 28±12.75. A statistically significant positive relationship was observed in this study between the mean score of spiritual attitude and the total score of burden in all its dimensions, namely, time dependence, as well as the developmental, physical, social and emotional dimensions. Providing strategies for improving spirituality, such as teaching spiritual self-care, can improve their burden. Given that such strategies are psychologically approved and pose no side effects, they can be used as an effective, low-cost and risk-free approach for all caregivers, so that they can acquire the necessary spiritual support for overcoming the stress caused by caring for family members through the reinforcement of their spiritual beliefs in the ultimate effort to provide effective care to older patients while maintaining their own health and quality of life.

Human Papillomavirus (HPV) virion induced cancer and subfertility, two sides of the same coin.

In the natural history of HPV infections, the HPV virions can induce two different pathways, namely the infec- tious virion producing pathway and the clonal transforming pathway. An overview is given of the burden that is associated with HPV infections that can both lead to cervical cancer and/or temporal subfertility. That HPV infections cause serious global health burden due to HPV-associated cancers is common knowledge, but that it is also responsible for a substantial part of idiopathic subfertility is greatly underestimated. The bulk of the detected HPV DNA whether in men or women is however infectious from origin. Because the dissociation between HPV viruses and HPV virions or infection and disease remains difficult for clinicians as well as for HPV detection, we propose a review of the different effects caused by the two different HPV virion induced pathways, and highlight the mechanisms that are responsible for causing transient subfertility and cancer.

Armed conflict and related violence, including terrorism and one-sided violence, has profound effects on people's health and lives. The purpose of this study was to determine the relationship between deaths due to terrorism, civil war and one-sided violence from 1994-2000 and disability-adjusted life years (DALYs) occurring in 2002 attributable to all causes and specific communicable and noncommunicable diseases. Deaths resulting from terrorism, war and one-sided violence were positively associated with all cause as well as a number of communicable and noncommunicable disease-specific DALYs across the majority of sex and age subgroups of the populace, controlling for an array of economic factors empirically shown to affect public health. Overall, a 1.0% increase in deaths due to terrorism, civil war and one-sided violence from 1994-2000 was associated with a 0.16% increase in DALYs lost to all causes in 2002 in the total world population. There was little variation in the magnitude of these associations between males and females and between communicable and noncommunicable diseases. The results of the present study can begin to guide post-conflict recovery by focusing on interventions targeting both noncommunicable as well as communicable diseases, thereby highlighting the full health costs of war and ultimately providing a strong rationale for promoting peace.

Objective. Hypertension is the largest threat to patient health and a burden to health care systems. Despite various options, 30% of patients do not respond sufficiently to medical treatment. Mechanoreceptors in the aortic arch relay blood pressure (BP) levels through vagal nerve (VN) fibers to the brainstem and trigger the baroreflex, lowering the BP. Selective electrical stimulation of these nerve fibers reduced BP in rats. However, there is no technique described to localize and stimulate these fibers inside the VN without inadvertent stimulation of non-baroreceptive fibers causing side effects like bradycardia and bradypnea. Approach. We present a novel method for selective VN stimulation to reduce BP without the aforementioned side effects. Baroreceptor compound activity of rat VN (n = 5) was localized using a multichannel cuff electrode, true tripolar recording and a coherent averaging algorithm triggered by BP or electrocardiogram. Main results. Tripolar stimulation over electrodes near the barofibers reduced the BP without triggering significant bradycardia and bradypnea. The BP drop was adjusted to 60% of the initial value by varying the stimulation pulse width and duration, and lasted up to five times longer than the stimulation. Significance. The presented method is robust to impedance changes, independent of the electrode's relative position, does not compromise the nerve and can run on implantable, ultra-low power signal processors.

Outpatient chemotherapy is a core treatment for haematological malignancies; however, its toxicities frequently lead to distressing/potentially life-threatening side-effects (neutropenia/infection, nausea/vomiting, mucositis, constipation/diarrhoea, fatigue). Early detection/management of side-effects is vital to improve patient outcomes, decrease morbidity and limit lengthy/costly hospital admissions. The ability to capture patient-reported health data in real-time, is regarded as the 'gold-standard' to allow rapid clinical decision-making/intervention. This paper presents the protocol for a Phase 3 multi-site randomised controlled trial evaluating a novel nurse-led Telehealth intervention for remote monitoring/management of chemotherapy side-effects in Australian haematological cancer patients. Two hundred and twenty-two patients will be recruited from two hospitals. Eligibility criteria include: diagnosis of chronic lymphocytic leukaemia/Hodgkin's/non-Hodgkin's lymphoma; aged ≥ 18 years; receiving ≥ 2 cycles chemotherapy. Patients will be randomised 1:1 to either the control or intervention arm with stratification by diagnosis, chemotherapy toxicity (high versus low), receipt of previous chemotherapy and hospital. Patients allocated to the control arm will receive 'Usual Care' whilst those allocated to the intervention will receive the intervention in addition to 'Usual Care'. Intervention patients will be provided with a computer tablet and software prompting twice-daily completion of physical/emotional scales for up to four chemotherapy cycles. Should patient data exceed pre-determined limits an Email alert is delivered to the treatment team, prompting nurses to view patient data, and contact the patient to provide clinical intervention. In addition, six scheduled nursing interventions will be completed to educate/support patients in use of the software. Patient outcomes will be measured cyclically (midpoint and end of cycles) via pen-and-paper self-report alongside review of the patient medical record. The primary outcome is burden due to nausea, mucositis, constipation and fatigue. Secondary outcomes include: burden due to vomiting and diarrhoea; psychological distress; ability to self-manage health; level of cancer information/support needs and; utilisation of health services. Analyses will be intention-to-treat. A cost-effectiveness analysis is planned. This trial is the first in the world to test a remote monitoring/management intervention for adult haematological cancer patients receiving chemotherapy. Future use of such interventions have the potential to improve patient outcomes/safety and decrease health care costs by enabling early detection/clinical intervention. ACTRN12614000516684 .

Impact of adherence on the outcome of antiviral therapy for chronic hepatitis C.

Mulhall, Brian P; Younossi, Zobair

2005-01-01

Nearly 4 million people in the United States have evidence of hepatitis C infection (HCV), representing a significant cause of cirrhosis and liver cancer as well a major burden to our healthcare systems and society. Antiviral therapy can successfully eradicate HCV over the long term, potentially reducing the risk of progression and improving patients' quality of life. The currently preferred HCV treatment is a combination of pegylated interferon alfa and ribavirin, which can achieve an overall sustained viral eradication rate of 55%. The duration of this treatment is typically determined by HCV genotype and the patient's early virologic response to the antiviral regimen. Evidence has accumulated over the past few years to indicate that close adherence to the optimal antiviral regimen can enhance sustained virologic response. But optimal treatment outcomes require diligence and careful management of side effects related to combination therapy. Although reducing the dose of pegylated interferon alfa, ribavirin, or both can effectively treat side effects, suboptimal doses of this regimen, especially ribavirin, may negatively affect virologic response. An alternative strategy is to use growth factors to treat cytopenias. This strategy can obviate dose reductions while potentially improving patients' quality of life. Patient support seems especially important early after the initiation of antiviral therapy. Encouraging study findings involving the growth factors, epoetin alfa and darbepoetin alfa, suggest improved anemia and quality of life while maintaining the optimal ribavirin dose. Future work should be aimed at providing stronger evidence for the use of these "supportive products" during anti-HCV therapy. As we strive to develop better treatment options for our HCV patients, the importance of adhering to the treatment regimen continues to play a central role. Effective side effect management is crucial for the success of this treatment because adherence is negatively affected by side effects related to the antiviral regimen. By identifying and addressing the important side effects of combination therapy for HCV, adherence to treatment can be improved and optimal outcomes can be achieved.

Pain remains a tremendous burden on patients and for the health care system, with uncontrolled pain being the leading cause of disability in this country. There are a variety of medications that can be used in the treatment of pain, including ketorolac, oxymorphone, tapentadol, and tramadol. Depending on the clinical situation, these drugs can be used as monotherapy or in conjunction with other types of medications in a multimodal approach. A strong appreciation of pharmacologic properties of these agents and potential side effects is warranted for clinicians. Copyright © 2017 Elsevier Inc. All rights reserved.

Epidemiologic, socioeconomic and psychosocial aspects in lupus erythematosus.

Aberer, E

2010-08-01

Epidemiologic, socioeconomic, and psychosocial factors play an important role in health care and handling of patients with the various clinical forms of lupus erythematosus (LE). Patients with LE are mostly young women; adolescents and some ethnic groups are especially prone to a severe course of disease. The unpredictable and fluctuating flares of disease, the need for longterm treatment, and the side effects and damage caused by the disease itself severely reduce quality of life. Problems arise, involving family members, adherence to medical advice and therapy, communication and self management. Socioeconomically, patients are often unable to take regular employment and to pay for health insurance. Stress factors that arise have a negative impact on the course of disease, increasing both fatigue and the basic burden of illness. Healthcare professionals must pay careful attention to all these items, as they attempt to treat flares, minimize drug side effects, provide pain relief, arrange communication and exercise programs along with behavioral and psychosocial interventions in multidisciplinary cooperation, and also involve and support family members.

Schizophrenia in women and children: a selective review of literature from developing countries.

Women and children with psychotic disorders in developing countries may be vulnerable and have considerable social disadvantages. Gender disadvantage has implications for all health outcomes including mental illnesses. In the more relevant gender-related context we discuss several important issues which affect women with schizophrenia, namely stigma, caregiver burden, functional outcome, marriage, victimization and help-seeking. The findings indicate that there are variations in clinical and functional outcomes and age of onset of illness between different regions. Drug side effects, such as metabolic syndrome appear to be quite common, adding to disease burden in women from developing countries. Victimization and coercion may contribute to poor quality of life and health concerns such as STIs and HIV. Stigma among women with schizophrenia appears to play a major role in help-seeking, caregiver burden and issues such as marriage and parenting. Gender-sensitive care and practices are few and not well documented. Research in the area of psychoses in children and adolescents from LAMI countries is sparse and is mainly restricted to a few clinic-based studies. More research is needed on organic and medical factors contributing to childhood psychoses, pathways to care, help-seeking, and impact of early detection and community care.

A clinician's understanding of ethics in palliative care: an American perspective.

PubMed

Cimino, James E

2003-04-01

I believe the standard for making ethical decisions should be the same for all patients: appropriate medical interventions, carefully weighing their benefits and burdens, and trying to honor the wishes of the patients. When cure is not possible, the balance between benefits and burdens should shift to greater consideration of the burden side of the equation. The ascendancy of autonomy over other medical ethical principles is the center for most of the ethical dilemmas encountered in palliative care. This paper discusses the issues of autonomy, informed consent, patient capacity, advance directives, futility, "do-not-resuscitate" orders, withholding or withdrawing interventions, euthanasia, and sedation therapy. After 41 years of my personally caring for over 4000 terminally ill patients, primarily at Calvary Hospital, the most practical approach has been to establish trust with patients and families, determining their goals, and diligently applying the principles of beneficence (benefits) and nonmaleficence (burdens) in everyday practice.

Pain and Poppies: The Good, the Bad, and the Ugly of Opioid Analgesics

2015-01-01

Treating pain is one of the most difficult challenges in medicine and a key facet of disease management. The isolation of morphine by Friedrich Sertürner in 1804 added an essential pharmacological tool in the treatment of pain and spawned the discovery of a new class of drugs known collectively as opioid analgesics. Revered for their potent pain-relieving effects, even Morpheus the god of dreams could not have dreamt that his opium tincture would be both a gift and a burden to humankind. To date, morphine and other opioids remain essential analgesics for alleviating pain. However, their use is plagued by major side effects, such as analgesic tolerance (diminished pain-relieving effects), hyperalgesia (increased pain sensitivity), and drug dependence. This review highlights recent advances in understanding the key causes of these adverse effects and explores the effect of chronic pain on opioid reward. SIGNIFICANCE STATEMENT Chronic pain is pervasive and afflicts >100 million Americans. Treating pain in these individuals is notoriously difficult and often requires opioids, one of the most powerful and effective classes of drugs used for controlling pain. However, their use is plagued by major side effects, such as a loss of pain-relieving effects (analgesic tolerance), paradoxical pain (hyperalgesia), and addiction. Despite the potential side effects, opioids remain the pharmacological cornerstone of modern pain therapy. This review highlights recent breakthroughs in understanding the key causes of these adverse effects and explores the cellular control of opioid systems in reward and aversion. The findings will challenge traditional views of the good, the bad, and the ugly of opioids. PMID:26468188

Environmental Impacts of the U.S. Health Care System and Effects on Public Health.

The U.S. health care sector is highly interconnected with industrial activities that emit much of the nation's pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle assessment (EIOLCA) modeling using National Health Expenditures (NHE) for the decade 2003-2013 and compared to national totals. In 2013, the health care sector was also responsible for significant fractions of national air pollution emissions and impacts, including acid rain (12%), greenhouse gas emissions (10%), smog formation (10%) criteria air pollutants (9%), stratospheric ozone depletion (1%), and carcinogenic and non-carcinogenic air toxics (1-2%). The largest contributors to impacts are discussed from both the supply side (EIOLCA economic sectors) and demand side (NHE categories), as are trends over the study period. Health damages from these pollutants are estimated at 470,000 DALYs lost from pollution-related disease, or 405,000 DALYs when adjusted for recent shifts in power generation sector emissions. These indirect health burdens are commensurate with the 44,000-98,000 people who die in hospitals each year in the U.S. as a result of preventable medical errors, but are currently not attributed to our health system. Concerted efforts to improve environmental performance of health care could reduce expenditures directly through waste reduction and energy savings, and indirectly through reducing pollution burden on public health, and ought to be included in efforts to improve health care quality and safety.

Abstract Introduction Laxatives are commonly used to treat opioid-induced constipation, the commonest and most bothersome complication of opioids. However, laxatives have a nonspecific action and do not target underlying mechanisms of opioid-induced constipation; their use is associated with abdominal symptoms that negatively impact quality of life. Objective To assess the effects of laxatives in patients taking opioids for chronic pain. Methods One hundred ninety-eight UK patients who had taken opioid analgesics for at least one month completed a cross-sectional online or telephone survey. Questions addressed their pain condition, medication, and laxative use (including efficacy and side effects). The survey also assessed bowel function using the Bowel Function Index. Results Since starting their current opioid, 134 of 184 patients (73%) had used laxatives at some point and 122 (91%) of these were currently taking them. The most common laxatives were osmotics and stimulants. Laxative side effects were reported in 75%, most commonly gas, bloating/fullness, and a sudden urge to defecate. Side effects were more common in patients less than 40 years of age. Approximately half of patients said laxatives interfered with work and social activities, and one-fifth needed an overnight hospital stay because of their pain condition and/or constipation. Laxatives did not improve the symptoms of constipation, as assessed by the Bowel Function Index. Constipation was not related to opioid strength, dose of opioid, or number of laxatives taken. Conclusions Use of laxatives to treat opioid-induced constipation is often ineffective and associated with side effects. Instead of relieving the burden of opioid-induced constipation, laxative use is associated with a negative impact. PMID:28339544

Methimazole (MMI) and propylthiouracil (PTU) are both associated with birth defects and may also rarely be associated with agranulocytosis and liver failure. The frequency of these side effects when antithyroid drugs (ATDs) are used in the population in general or in pregnancy remains to be elucidated. All individuals registered as the parent of a live-born child in Denmark, 1973–2008, were identified (n = 2 299 952) and studied from 1995 through 2010 for the use of ATDs. Outcomes were agranulocytosis, liver failure, and birth defects in their offspring. To evaluate the frequency of these side effects associated with the use of ATDs in pregnancy, all live-born pregnancies (n = 830 680), 1996–2008, were identified in a subanalysis. In the population studied, 28 998 individuals redeemed prescriptions of ATDs (exposure in 2115 pregnancies), which was associated with 45 cases of agranulocytosis (one in pregnancy) and 10 cases of liver failure (one in pregnancy). This corresponded to 41 and 11 cases of agranulocytosis and liver failure per 5 million inhabitants during a 10-year period (agranulocytosis: 0.16% of ATDs exposed [MMI: 0.11% vs PTU: 0.27%, P = .02]; liver failure: 0.03% of ATDs exposed [MMI: 0.03% vs PTU: 0.05%, P = .4]). The majority (83%) developed the side effect within 3 months of ATD treatment and 25% during hyperthyroidism relapse. The use of ATDs in pregnancy was associated with birth defects in 3.4% of exposed children (44 cases per 5 million inhabitants per 10 y), and the frequency of birth defects after ATD exposure was 75 times higher than both maternal agranulocytosis and liver failure in pregnancy. In the Danish population in general, ATDs associated birth defects and agranulocytosis had similar frequencies and were more common than liver failure, whereas for the use of ATDs in pregnancy, birth defects were dominant. The burden of side effects to the use of ATDs can be reduced by restricting the use of ATDs in early pregnancy.

Research on intravenous fluid therapy and its side effects, volume, sodium, and chloride overload, has focused almost exclusively on the resuscitation setting. We aimed to quantify all fluid sources in the ICU and assess fluid creep, the hidden and unintentional volume administered as a vehicle for medication or electrolytes. We precisely recorded the volume, sodium, and chloride burdens imposed by every fluid source administered to 14,654 patients during the cumulative 103,098 days they resided in our 45-bed tertiary ICU and simulated the impact of important strategic fluid choices on patients' chloride burdens. In septic patients, we assessed the impact of the different fluid sources on cumulative fluid balance, an established marker of morbidity. Maintenance and replacement fluids accounted for 24.7% of the mean daily total fluid volume, thereby far exceeding resuscitation fluids (6.5%) and were the most important sources of sodium and chloride. Fluid creep represented a striking 32.6% of the mean daily total fluid volume [median 645 mL (IQR 308-1039 mL)]. Chloride levels can be more effectively reduced by adopting a hypotonic maintenance strategy [a daily difference in chloride burden of 30.8 mmol (95% CI 30.5-31.1)] than a balanced resuscitation strategy [daily difference 3.0 mmol (95% CI 2.9-3.1)]. In septic patients, non-resuscitation fluids had a larger absolute impact on cumulative fluid balance than did resuscitation fluids. Inadvertent daily volume, sodium, and chloride loading should be avoided when prescribing maintenance fluids in view of the vast amounts of fluid creep. This is especially important when adopting an isotonic maintenance strategy.

Tobacco produces an impressive burden of disease resulting in premature death in half of users. Despite effective smoking cessation medications (nicotine replacement therapies, bupropion and varenicline), there is a very high rate of relapse following quit attempts. The use of efficient strategies for the development of novel treatments is a necessity. A 'bench to bedside strategy' was initially used to develop cannabinoid CB1 receptor antagonists for the treatment of nicotine addiction. Unfortunately, after being tested on experimental animals, what seemed to be an interesting approach for the treatment of nicotine addiction resulted in serious unwanted side effects when tested in humans. Current research is focusing again on pre-clinical models in an effort to eliminate unwanted side effects while preserving the initially observed efficacy. A 'bed side to bench strategy' was used to study the role of the insula (part of the frontal cortex) in nicotine addiction. This line of research started based on clinical observations that patients suffering stroke-induced lesions to the insula showed a greater likelihood to report immediate smoking cessation without craving or relapse. Subsequently, animal models of addiction are used to explore the role of insula in addiction. Due to the inherent limitations existing in clinical versus preclinical studies, the possibility of close interaction between both models seems to be critical for the successful development of novel therapeutic strategies for nicotine dependence. © 2013.

Tree pollen induced allergies are one of the major medical and public health burdens in the industrialized world. Allergen-Specific Immunotherapy (AIT) through subcutaneous injection or sublingual delivery is the only approved therapy with curative potential to pollen induced allergies. AIT often is associated with severe side effects and requires long-term treatment. Safer, more effective and convenient allergen specific immunotherapies remain an unmet need. In this review article, we discuss the current progress in applying protein and peptide-based approaches and DNA vaccines to the clinical challenges posed by tree pollen allergies through the lens of preclinical animal models and clinical trials, with an emphasis on the birch and Japanese red cedar pollen induced allergies.

Purpose of review Pediatric uveitis is relatively uncommon, accounting for only 5–10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. Recent findings Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. Summary We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease. PMID:23872814

Digital interventions can change patients' experiences of managing their health, either creating additional burden or improving their experience of healthcare. This qualitative study aimed to explore perceived burdens and benefits for patients using a digital self-management intervention for reducing high blood pressure. A secondary aim was to further our understanding of how best to capture burdens and benefits when evaluating health interventions. Inductive qualitative process study nested in a randomised controlled trial. Primary Care in the UK. 35 participants taking antihypertensive medication and with uncontrolled blood pressure at baseline participated in semistructured telephone interviews. Digital self-management intervention to support blood pressure self-monitoring and medication change when recommended by the healthcare professional. Data were analysed using inductive thematic analysis with techniques from grounded theory. Seven themes were developed which reflected perceived burdens and benefits of using the intervention, including worry about health, uncertainty about self-monitoring and reassurance. The analysis showed how beliefs about their condition and treatment appeared to influence participants' appraisal of the value of the intervention. This suggested that considering illness and treatment perceptions in Burden of Treatment theory could further our understanding of how individuals appraise the personal costs and benefits of self-managing their health. Patients' appraisal of the burden or benefit of using a complex self-management intervention seemed to be influenced by experiences within the intervention (such as perceived availability of support) and beliefs about their condition and treatment (such as perceived control and risk of side effects). Developing our ability to adequately capture these salient burdens and benefits for patients could help enhance evaluation of self-management interventions in the future. Many participants perceived important benefits from using the intervention, highlighting the need for theory to recognise that engaging in self-management can include positive as well as negative aspects.

The Michigan Oncology Quality Consortium (MOQC) is a continuous quality improvement collaborative seeking to improve oncology care in Michigan, including for patients taking oral chemotherapy. The aim of this study was to assess the relationship between patient activation, confidence to self-manage side effects, and adherence to oral oncolytics to inform future oncology care. A multicenter cross-sectional observational study was conducted using an online survey to examine patient activation (patient activation measure, PAM), health literacy, symptom burden (Edmonton Symptom Assessment System, ESAS), confidence to self-manage side effects (fatigue, nausea, and diarrhea), and adherence to oral oncolytics. Inclusion criteria were patients taking an oral oncolytic for at least 1 month. Bivariate analyses and logistic regression were performed to evaluate relationships between the variables. A total of 125 respondents, mean (SD) age 66.2 (13.6), 57.7% female, and 95.1% Caucasian completed the survey. The mean (SD) PAM score was 65.0 (18.0). Confidence to manage fatigue, nausea, and diarrhea was associated with higher activation, and confidence to self-manage fatigue and diarrhea were associated with higher health literacy. About 30% of participants reported some level of non-adherence to oral oncolytics, and those who experienced side effects (Fisher's exact test p = 0.033) and with shorter length of therapy (t test p = 0.027) were significantly more likely to be non-adherent. These findings show that there is room for improvement across practices involved with MOQC with regard to supporting patients taking oral oncolytics. Patients will need to improve their activation levels, and oncology clinics will need to create new workflows in order to enhance self-care management ability for patients taking oral oncolytics.

Human Papillomavirus (HPV) virion induced cancer and subfertility, two sides of the same coin

Abstract In the natural history of HPV infections, the HPV virions can induce two different pathways, namely the infec- tious virion producing pathway and the clonal transforming pathway. An overview is given of the burden that is associated with HPV infections that can both lead to cervical cancer and/or temporal subfertility. That HPV infections cause serious global health burden due to HPV-associated cancers is common knowledge, but that it is also responsible for a substantial part of idiopathic subfertility is greatly underestimated. The bulk of the detected HPV DNA whether in men or women is however infectious from origin. Because the dissociation between HPV viruses and HPV virions or infection and disease remains difficult for clinicians as well as for HPV detection, we propose a review of the different effects caused by the two different HPV virion induced pathways, and highlight the mechanisms that are responsible for causing transient subfertility and cancer.

[Memantine: from the original brand to generics].

PubMed

Titova, N V

Memantine is the first clinically available glutamate antagonist, with an antagonist action at the N-methyl-D-aspartate receptors in the brain, for correction of cognitive and behavioral functions in neurodegenerative disorders. Glutamate mediated excitotoxic neuronal damage has been implicated in Alzheimer's disease (AD) and other parkinsonism-related dementias and, therefore, memantine represents a novel mode of action to counteract the glutamate-mediated excitotoxicity. In moderate to severe AD, 20 mg of memantine shows a positive effect on cognition, mood, behavior and the ability to perform activities of daily living. Long-term studies show good tolerability of memantine with an acceptable side-effect profile. In recent years, there have been a proliferation of a number of companies producing generic memantine with different trade names. In Russia, the first memantine generic drug noojerone was approved in 2010 and its use has since been supported by a growing evidence base of efficacy in real-life clinical practice. Postmarketing studies show that noojerone provides long-term and effective therapy in patients with moderate and severe Alzheimer's dementia. This observation is supported by the clinically significant therapeutic effect of noojerone on cognitive and daily functioning, behavioral and psychotic symptoms of dementia and a reduction of the burden on caregivers. This generic version of memantine is affordable and, therefore, reduces financial burden on patients and improves compliance with treatment.

The purpose of the present study was to evaluate the tissue characteristics of plaques with moderate or mild stenosis in the inner and outer curvature of the left anterior descending artery (LAD) using integrated backscatter intravascular ultrasound. We evaluated 66 plaques with moderate stenosis (plaque burden >50% but ≤75%) and 49 plaques with mild stenosis (plaque burden >30% but ≤50%) in 66 patients undergoing percutaneous intervention to the LAD. All plaques were >10mm away from any side branch or previously implanted stents. We divided vessel cross-sections into four quadrants (inner curvature, outer curvature, clockwise lateral side, and counterclockwise lateral side) using the septal branch as a landmark for the inner curvature. We averaged relative lipid area, relative fibrous area, and relative calcified area in minimal lumen area (MLA), three cross-sections proximal to the site of MLA, and three cross-sections distal to the site of MLA. In plaques with moderate stenosis, the relative lipid area in the inner curvature was significantly greater than in the outer curvature and lateral sides, whereas there was no significant difference in plaques with mild stenosis. The present study provides new findings that lipid pool is clustered in the inner curvature and fibrous tissue is clustered in the outer curvature of plaques with moderate stenosis in non-branching LAD lesions.

Chronic pain is a prevalent condition in the United States. Musculoskeletal pain, including joint and back pain, is the most common type of chronic pain, and many patients with back pain have a neuropathic component. Pain has direct economic consequences. While oxycodone controlled-release (CR) is one of the most widely used oral long-acting opioids for pain, including pain with a neuropathic component, it is often associated with bothersome side effects, resulting in additional medical resource use (MRU) and costs. To examine the impact on MRU and costs to payers of side effects in patients taking oxycodone CR alone or in combination with other pain medications for noncancer pain (including those with neuropathic pain symptoms). A nationwide convenience sample of adults in the United States, who participated in a survey research panel and reported current use of oxycodone CR for noncancer pain, completed an online survey between November 2, 2010, and December 13, 2010. Respondents were excluded if they reported current use of other extended-release or long-acting opioid prescription medications. The survey consisted of questions on demographics, clinical characteristics, pain characteristics, experience with pain medication, and MRU associated with side effects. Payer costs were calculated based on the MRU reported by the respondents multiplied by Medicare reimbursement rates for hospitalizations and outpatient visits and average wholesale price (AWP) minus 20% for medications. A subgroup of patients who reported neuropathic pain symptoms also was examined. After applying the exclusion criteria, 432 respondents completed the survey. Approximately half of the respondents (n = 219; 50.7%) reported neuropathic pain symptoms. The majority of respondents were Caucasian (88.4%) and female (63.7%) with an average age of 41.8 years (14.89). Respondents most frequently reported low back pain (41.2%), followed by osteoarthritis/rheumatoid arthritis (20.4%), neuropathic pain (10.6%), and fibromyalgia (9.0%). Respondents reported having their pain condition for an average of 5.4 (7.42) years. On days when taken, respondents reported a mean oxycodone CR daily dose of 83.3 mg (126.93) taken in an average of 2 doses. Most respondents (82.4%) reported experiencing at least 1 side effect with 77.5% being bothered by at least 1 side effect. The most frequently reported side effects ( greater than 25%) were drowsiness (41.4%), constipation (37.0%), fatigue or daytime sleepiness (36.6%), and dizziness (27.1%). Among respondents who reported being bothered by one or more side effects in the previous month, MRU associated with side effects was reported by 39.1% of respondents and significantly increased as the level of side-effect bother increased from 19.8% among those "A little bit bothered" to 38.4% among those "Bothered" to 61.0% among those "Extremely bothered" (P less than 0.001). Additionally, total average payer costs (in 2010 dollars) per respondent in the previous month associated with side effects were $238 ($1,159) and also significantly increased as the level of side-effect bother increased from $61 ($512) among those "A little bit bothered" to $238 ($1,160) among those "Bothered" to $425 ($1,561) among those "Extremely bothered" (P less than 0.001). Results reported in the neuropathic pain subgroup were similar to results reported in the total study sample. Among adults taking oxycodone CR for chronic noncancer pain (with or without a neuropathic pain component), over three-fourths reported being bothered by side effects. Respondents who reported higher levels of side-effect bother also reported greater MRU, resulting in increased payer costs. The results of this study provide further support of the econo-mic burden to payers associated with opioid-related side effects in patients with chronic noncancer pain, with and without neuropathic pain.

Treating pain is one of the most difficult challenges in medicine and a key facet of disease management. The isolation of morphine by Friedrich Sertürner in 1804 added an essential pharmacological tool in the treatment of pain and spawned the discovery of a new class of drugs known collectively as opioid analgesics. Revered for their potent pain-relieving effects, even Morpheus the god of dreams could not have dreamt that his opium tincture would be both a gift and a burden to humankind. To date, morphine and other opioids remain essential analgesics for alleviating pain. However, their use is plagued by major side effects, such as analgesic tolerance (diminished pain-relieving effects), hyperalgesia (increased pain sensitivity), and drug dependence. This review highlights recent advances in understanding the key causes of these adverse effects and explores the effect of chronic pain on opioid reward. Chronic pain is pervasive and afflicts >100 million Americans. Treating pain in these individuals is notoriously difficult and often requires opioids, one of the most powerful and effective classes of drugs used for controlling pain. However, their use is plagued by major side effects, such as a loss of pain-relieving effects (analgesic tolerance), paradoxical pain (hyperalgesia), and addiction. Despite the potential side effects, opioids remain the pharmacological cornerstone of modern pain therapy. This review highlights recent breakthroughs in understanding the key causes of these adverse effects and explores the cellular control of opioid systems in reward and aversion. The findings will challenge traditional views of the good, the bad, and the ugly of opioids. Copyright © 2015 the authors 0270-6474/15/3513879-10$15.00/0.

Objectives Clinical management of giant cell arteritis (GCA) involves balancing the risks and burdens arising from the disease with those arising from treatment, but there is little research on the nature of those burdens. We aimed to explore the impact of giant cell arteritis (GCA) and its treatment on patients’ lives. Methods UK patients with GCA participated in semi-structured telephone interviews. Inductive thematic analysis was employed. Results 24 participants were recruited (age: 65–92 years, time since diagnosis: 2 months to >6 years). The overarching themes from analysis were: ongoing symptoms of the disease and its treatment; and ‘life-changing’ impacts. The overall impact of GCA on patients’ lives arose from a changing combination of symptoms, side effects, adaptations to everyday life and impacts on sense of normality. Important factors contributing to loss of normality were glucocorticoid-related treatment burdens and fear about possible future loss of vision. Conclusions The impact of GCA in patients’ everyday lives can be substantial, multifaceted and ongoing despite apparent control of disease activity. The findings of this study will help doctors better understand patient priorities, legitimise patients’ experiences of GCA and work with patients to set realistic treatment goals and plan adaptations to their everyday lives.

Individual decisions to vaccinate one's child or oneself: A discrete choice experiment rejecting free-riding motives.

Verelst, Frederik; Willem, Lander; Kessels, Roselinde; Beutels, Philippe

It is essential for public health to understand what drives people's hesitance towards vaccination. Theoretical models of vaccination decisions are ubiquitous, often incorporating herd immunity, perceptions of vaccine-related side-effects (VRSE) and of vaccine-preventable burden of disease, but with little to no empirical exploration. Herd immunity is a (usually) positive externality where vaccinated individuals influence others' risks by their reduced capability to transmit an infectious disease to them. It is often assumed that (rational) individuals incorporate this externality in their strategic vaccination decision, from which free-riding behavior arises. We performed a Bayesian D-efficient discrete choice experiment in February-March 2017 to study vaccination behavior in 1919 Belgian respondents. Choice sets with vaccine profiles were constructed using six attributes: vaccine effectiveness, VRSE, accessibility (in terms of convenience and reimbursement), vaccine-preventable burden of disease, local (respondents' network of contacts) vaccination coverage, and population (the population at large) vaccination coverage. VRSE and accessibility are the most influential attributes, followed by vaccine effectiveness and burden of disease. Both population and local coverage are less important than the other attributes, but show a significant direct linear relationship with vaccine utility. This supports the existence of peer influence (more incentivized as more and more vaccinate), rather than free-riding on herd immunity. These findings were independent of whether respondents made vaccine choices for themselves or for their child. Around 40% of the respondents indicated accepting vaccination with little or no questioning. These 'acceptors' were less sensitive to changes in the vaccine-preventable burden of disease for their child's vaccination choices (but not for themselves). Public health institutions are critical in stimulating vaccine uptake by making vaccines conveniently available at an affordable price and by communicating pro-actively on perceived VRSEs. The free-riding assumption as a driver of individual vaccine decisions, seems inappropriate, but this observation needs confirming in other populations. Copyright © 2018 Elsevier Ltd.

Environmental Impacts of the U.S. Health Care System and Effects on Public Health

Eckelman, Matthew J.; Sherman, Jodi

The U.S. health care sector is highly interconnected with industrial activities that emit much of the nation’s pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle assessment (EIOLCA) modeling using National Health Expenditures (NHE) for the decade 2003–2013 and compared to national totals. In 2013, the health care sector was also responsible for significant fractions of national air pollution emissions and impacts, including acid rain (12%), greenhouse gas emissions (10%), smog formation (10%) criteria air pollutants (9%), stratospheric ozone depletion (1%), and carcinogenic and non-carcinogenic air toxics (1–2%). The largest contributors to impacts are discussed from both the supply side (EIOLCA economic sectors) and demand side (NHE categories), as are trends over the study period. Health damages from these pollutants are estimated at 470,000 DALYs lost from pollution-related disease, or 405,000 DALYs when adjusted for recent shifts in power generation sector emissions. These indirect health burdens are commensurate with the 44,000–98,000 people who die in hospitals each year in the U.S. as a result of preventable medical errors, but are currently not attributed to our health system. Concerted efforts to improve environmental performance of health care could reduce expenditures directly through waste reduction and energy savings, and indirectly through reducing pollution burden on public health, and ought to be included in efforts to improve health care quality and safety.

Aim of this study was to evaluate the advantages of electron beam irradiation compared to kilovoltage X-ray therapy in the treatment of keloids. Furthermore, the risk of developing malignancy following keloid radiotherapy was assessed. An automatic water phantom was used to evaluate the dose distribution in tissue. Furthermore, a series of measurements was done on the patients using thermoluminescence dosimeters (TLD) to estimate the doses absorbed by the organs at risk. We also report our clinical experience with electron beam radiation of 134 keloids following surgical excision. Electron beam irradiation offers a high control rate (84%) with minimal side effects for keloids. Electron irradiation provides better dose distribution in tissue, and therefore less radiation burden to the organs at risk. After a mean follow-up period of 7.2 years, no severe side effects or malignancies were observed after keloid radiotherapy. Electron radiation therapy is superior to kilovoltage irradiation for treating keloids due to better dose distribution in tissue. In agreement with the literature, no cases of malignancy were observed after keloid irradiation.

Pharmacotherapy for chronic non-specific low back pain: current and future options.

Low back pain is associated with a large burden-of-illness. It is responsible for the most years lived with disability as compared with any other medical condition. A comprehensive overview of the evidence on pharmacological treatment options for chronic low back pain is lacking. This review evaluates the evidence for the benefits and risks of currently available pharmacological treatments for chronic low back pain. Areas covered: The authors focus on the recent (Cochrane) systematic reviews and meta-analyses of randomized clinical trials covering paracetamol (acetaminophen), NSAIDs, muscle relaxants, antidepressants, anticonvulsants, opioids, and other (new) drugs. Expert opinion: The overall impression of the efficacy of pharmacological treatments for patients with chronic low back pain is rather sobering. The effects on pain reduction and improvement of function are commonly small to moderate and short lasting when compared to placebo. At the same time, the various types of drugs are not without side-effects. This holds especially true for serious side-effects associated with (prolonged) use of strong opioids. Future studies on patients with chronic back pain should aim to identify subgroups of patients with good response to specific pharmacological treatment to facilitate personalized care.

At present, therapy of children with chronic hepatitis B and C is still based on few drugs, all burdened by a series of side-effects, unsatisfactory serum conversion rates, and/or drug-resistance. Moreover, selection of subjects to treat with conventional therapies is not univocal, especially during the pediatric age when the disease course is often mild with significant spontaneous seroconversion rate. Our review deals with pros and cons points when a physician decides to design a drug therapy for a child with chronic viral hepatitis, and different possible therapeutic opportunities. A literature search was performed through PubMed. The newest articles, reviews, systematic reviews, and guidelines were included in this review. The management of children with viral hepatitis is still controversial over whom and when to treat and the use of drug(s). Novel therapeutic strategies have been evaluated only in clinical and preclinical trials involving, for instance, "therapeutic" vaccines. The data on safety and effectiveness of new drugs are also reviewed. The results of reported studies confirmed that at least some of the new drugs, with greater efficacy and/or minor side-effects, will be used clinically.

The goal of this project is to develop a novel and innovative mobile solution to address behavioral and psychological symptoms of dementia (BPSD) that occur in individuals with Alzheimer's. BPSD can include agitation, restlessness, aggression, apathy, obsessive-compulsive and repetitive behaviors, hallucinations, delusions, paranoia, and wandering. Alzheimer's currently affects 5.4 million adults in the United States and that number is projected to increase to 14 million by 2050. Almost 90% of all affected with AD experience BPSD, resulting in increased healthcare costs, heavier burden on caregivers, poor patient outcomes, early nursing home placement, long-term hospitalizations, and misuse of medications. Pharmacological support may have undesirable side effects such as sedation. Nonpharmacological interventions are alternative solutions that have shown to be effective without undesirable side effects. Music therapy has been found to lower BPSD symptoms significantly. Our study is based on combination of the reminiscence and the music therapies where past memorable events are recalled using prompts such as photos, videos, and music. We are proposing a mobile multimedia solution, a technical version of the combined reminiscence, and music therapies to prevent the occurrence of BPSD, especially for the rural population who have reduced access to dementia care services.

Pharmacotherapy for schizophrenia in postmenopausal women.

González-Rodríguez, Alexandre; Seeman, Mary V

Reduced estrogen levels at menopause mean a loss of the neuroprotection that is conferred, from puberty until menopause, on women with schizophrenia. The postmenopausal stage of schizophrenia requires therapeutic attention because women with this diagnosis almost invariably experience increased symptoms and increased side effects at this time. So far, few targeted therapies have been successfully developed. Areas covered: This non-systematic, narrative review is based on the relevant published literature indexed in PubMed. A digital search was combined with a manual check of references from studies in the field of gender differences, menopause and schizophrenia. Aside from the inclusion of a few early classic papers, the review focuses on 21st century basic, psychopharmacologic, and clinical literature on the treatment of women with schizophrenia after menopause. Expert opinion: Beyond a relatively low dose threshold, all antipsychotic medications have adverse effects, which become more prominent for women at the time of menopause. Estrogen modulators may not help all symptoms of schizophrenia but are, nevertheless, relatively safe and, when used as adjuncts, help to keep antipsychotic doses low, thus reducing the side effect burden. The field is currently moving towards precision medicine and individual genetic profiles will help to determine the efficacy of available treatments in the future.

Non-drug treatment of hypertension has become a research hotspot, which might overcome the heavy economic burden and side effects of drug treatment for the patients. Because of the good treatment effect and convenient operation, a new treatment based on slow breathing training is increasingly becoming a kind of physical therapy for hypertension. This paper explains the principle of hypertension treatment based on slow breathing training method, and introduces the overall structure of the portable blood pressure controlling instrument, including breathing detection circuit, the core control module, audio module, memory module and man-machine interaction module. We give a brief introduction to the instrument and the software in this paper. The prototype testing results showed that the treatment had a significant effect on controlling the blood pressure.

The purpose of the study is to describe from a relational perspective, partners' psychological adjustment, coping and support needs for advanced prostate cancer. A mixed methods design was adopted, employing triangulation of qualitative and quantitative data, to produce dyadic profiles of adjustment for six couples recruited from the urology clinics of local hospitals in Tasmania, Australia. Dyads completed a video-taped communication task, semi-structured interview and standardised self-report questionnaires. Themes identified were associated with the dyadic challenges of the disease experience (e.g. relationship intimacy, disease progression and carer burden). Couples with poor psychological adjustment profiles had both clinical and global locus of distress, treatment side-effects, carer burden and poor general health. Resilient couples demonstrated relationship closeness and adaptive cognitive and behavioural coping strategies. The themes informed the adaption of an effective program for couples coping with women's cancers (CanCOPE, to create a program for couples facing advanced prostate cancer (ProCOPE-Adv). Mixed method results inform the development of psychological therapy components for couples coping with advanced prostate cancer. The concomitance of co-morbid health problems may have implications for access and engagement for older adult populations in face-to-face intervention.

Antimicrobial resistance (AMR) is currently one of the major threats facing mankind. The emergence and rapid spread of multi- and pan-drug-resistant organisms (such as vancomycin-, methicillin-, extended-spectrum β-lactam-, carbapenem- and colistin-resistant organisms) has put the world in a dilemma. The health and economic burden associated with AMR on a global scale are dreadful. Available antimicrobials have been misused and are almost ineffective with some of these drugs associated with dangerous side effects in some individuals. Development of new, effective, and safe antimicrobials is one of the ways by which AMR burden can be reduced. The rate at which microorganisms develop AMR mechanisms outpaces the rate at which new antimicrobials are being developed. Medicinal plants are potential sources of new antimicrobial molecules. There is renewed interest in antimicrobial activities of phytochemicals. Nigeria boasts of a huge heritage of medicinal plants and there is avalanche of researches that have been undertaken to screen antimicrobial activities of these plants. Scientific compilation of these studies could provide useful information on the antimicrobial properties of the plants. This information can be useful in the development of new antimicrobial drugs. This paper reviews antimicrobial researches that have been undertaken on Nigerian medicinal plants. PMID:28512606

Restricted evaluation of Trichodectes canis (Phthiraptera: Trichodectidae) detection methods in Alaska gray wolves.

Trichodectes canis (Phthiraptera: Trichodectidae) was first documented on Alaska (USA) gray wolves (Canis lupus) on the Kenai Peninsula in 1981. In subsequent years, numerous wolves exhibited visually apparent, moderate to severe infestations. Currently, the Alaska Department of Fish and Game utilizes visual inspection, histopathology, and potassium hydroxide (KOH) hide digestion for T. canis detection. Our objective was to determine optimal sampling locations for T. canis detection. Wolf hides were subjected to lice enumeration using KOH hide digestion. Thirty nine of the 120 wolves examined had lice. Of these 39, total louse burdens ranged from 14 to an extrapolated 80,000. The hides of 12 infested animals were divided into 10 cm by 10 cm subsections and the lice enumerated on a subsection from each of four regions: neck; shoulder; groin; and rump. Combining the data from these 12 wolves, the highest mean proportions of the total louse burdens on individual wolves were found on the rump and differed significantly from the lowest mean proportion on the neck. However, examination of the four subsections failed to detect all infested wolves. Hides from 16 of the 39 infested animals were cut into left and right sides, and each side then cut into four, approximately equal sections: neck and shoulder; chest; abdomen; and rump. Half hides were totally digested from 11 wolves, and whole hides from 5. For these 21 half hides, the highest mean proportions of total louse burdens were found on the rump, and this section had the highest sensitivity for louse detection, regardless of burden. However, removal of this large section from a hide would likely be opposed by hunters and trappers.

The purpose of this work was to evaluate the patient-borne financial cost of common, adverse breast cancer treatment-associated effects, comparing cost across women with or without these side effects. Two hundred eighty-seven Australian women diagnosed with early-stage breast cancer were prospectively followed starting at 6 months post-surgery for 12 months, with three monthly assessments of detailed treatment-related side effects and their direct and indirect patient costs attributable to breast cancer. Bootstrapping statistics were used to analyze cost data, and adjusted logistic regression was used to evaluate the association between costs and adverse events from breast cancer. Costs were inflated and converted from 2002 Australian to 2014 US dollars. More than 90 % of women experienced at least one adverse effect (i.e., post-surgical issue, reaction to radiotherapy, upper-body symptoms or reduced function, lymphedema, fatigue, or weight gain). On average, women paid $5,636 (95 % confidence interval (CI), $4,694, $6,577) in total costs. Women with any one of the following symptoms (fatigue, reduced upper-body function, upper-body symptoms) or women who report ≥4 adverse treatment-related effects, have 1.5 to nearly 4 times the odds of having higher healthcare costs than women who do not report these complaints (p < 0.05). Women face substantial economic burden due to a range of treatment-related health problems, which may persist beyond the treatment period. Improving breast cancer care by incorporating prospective surveillance of treatment-related side effects and strategies for prevention and treatment of concerns (e.g., exercise) has real potential for reducing patient-borne costs.

Chronic pain affects a large percentage of the population, representing a socio-economic burden. Current treatments are characterised by suboptimal efficacy and/or side effects that limit their use. Among several approaches to treating chronic pain, voltage-sensitive Ca(2+) and Na(+) channels are promising targets. This review evaluates the preclinical evidence that supports the involvement of these targets, with specific attention to those subtypes that appear more strictly correlated with pain generation and sustainment, as well as those compounds that modulate the activity of Ca(2+) and/or Na(+) channels that are currently in clinical development for chronic pain conditions.

[Age-related macular degeneration – a challenge for public health care].

PubMed

Mantel, Irmela

2016-01-01

Age-related macular degeneration (AMD) is the predominant cause of legal blindness in the population over 50 years of age. The disorder shows exponentially increasing prevalence with age, and the late forms with their vision threatening evolution are found in approximately one third of cases. The late AMD may be purely atrophic and so far untreatable. Or it may be neovascular and exudative, for which medical treatment is available, consisting of repetitive intravitreous injections of Anti-VEGF molecules. The treatment is highly effective in blocking the growth of the pathological vessels and allowing resolution of the accompanying edema. Visual improvement is variable but often very meaningful for the patients. However, the final visual level depends mostly on early intervention. Thus, screening for the first signs of neovascular AMD is crucial for the endresult. However, the repetitive intraocular injections are an important burden for the patients. Due to the high patient numbers, the chronic care management with steadily adding new patients is a major challenge for treating institutions. Limited resources may put patients at risk of undertreatment with resulting visual loss. Various strategies have been developed to cope with the burden. In addition, the financial cost is high for the health care system. On the other hand, timely and ongoing treatment is the best investment to achieve meaningful visual improvement, which is extremely important for the quality of life and autonomy of the patients. Side effects of the treatment are limited and mostly procedure related. Systemic side effects are possible but despite the large studies not conclusive. However, care must be taken in cases of high cardiovascular risk, as thromboembolic risk increase may rarely happen. So far unsolved problems include the long term visual results, the degree of reversibility of neovascularization, and the missing treatment options of atrophic AMD. Basic and clinical research on various treatment options for AMD is ongoing, and some additional molecules are expected for the near future, hopefully not only for neovascular AMD but including atrophic AMD as well.

Elevated concentrations of doxorubicin are found in eccrine sweat glands of the palms and soles. We therefore evaluated an antiperspirant as preventive treatment for palmar-plantar erythrodysesthesia (hand-foot syndrome) in patients with metastatic breast cancer treated with pegylated liposomal doxorubicin. An antiperspirant containing aluminum chlorohydrate or placebo cream was applied to the left or right hand and foot in a double-blinded manner (intra-patient randomization). The primary endpoint was the rate of grade 2 or 3 palmar-plantar erythrodysesthesia. A secondary endpoint was the patient-reported symptom burden (tingling, numbness, pain, or skin problems). Using McNemar's matched pairs design, 53 patients were needed to detect a 20% difference between the treatment and placebo sides with a significance level of 5% and power of 90%. Grade 2 or 3 PPE occurred in 30 (58%) of 52 evaluable patients; in six patients adverse effects occurred on the placebo side but not on the treatment side, whereas one patient developed palmar-plantar erythrodysesthesia on the treatment side only (P = 0.07). Four patients developed grade 2 or 3 palmar-plantar erythrodysesthesia on their foot on the placebo side but not on the treatment side (P = 0.05). In the cohort with grade 2 or 3 palmar-plantar erythrodysesthesia there was a trend towards fewer dermatologic symptomatologies with the active treatment (P = 0.05), and no difference for other adverse events. Using topical aluminum chlorohydrate as an antiperspirant appears to reduce the incidence of grade 2 or 3 palmar-plantar erythrodysesthesia following pegylated liposomal doxorubicin chemotherapy for metastatic breast cancer.

In Search of a Safe Natural Sleep Aid.

PubMed

Rao, Theertham P; Ozeki, Motoko; Juneja, Lekh R

2015-01-01

Sleep deprivation is associated with an elevated risk of various diseases and leads to a poor quality of life and negative socioeconomic consequences. Sleep inducers such as drugs and herbal medicines may often lead to dependence and other side effects. L-Theanine (γ-glutamylethylamide), an amino acid naturally found abundant in tea leaves, has anxiolytic effects via the induction of α brain waves without additive and other side effects associated with conventional sleep inducers. Anxiolysis is required for the initiation of high-quality sleep. In this study, we review the mechanism(s), safety, and efficacy of L-theanine. Collectively, sleep studies based on an actigraph, the obstructive sleep apnea (OSA) sleep inventory questionnaire, wakeup after sleep onset (WASO) and automatic nervous system (ANS) assessment, sympathetic and parasympathetic nerve activities, and a pediatric sleep questionnaire (PSQ) suggest that the administration of 200 mg of L-theanine before bed may support improved sleep quality not by sedation but through anxiolysis. Because L-theanine does not induce daytime drowsiness, it may be useful at any time of the day. The no observable adverse effect level (NOAEL) for the oral administration of L-theanine was determined to be above 2000 mg/kg bw/day. KEY TEACHING POINTS: Sleep deprivation-associated morbidity is an increasing public health concern posing a substantial socioeconomic burden. Chronic sleep disorders may seriously affect quality of life and may be etiological factors in a number of chronic diseases such as depression, obesity, diabetes, and cardiovascular diseases. Most sleep inducers are sedatives and are often associated with addiction and other side effects. L-Theanine promotes relaxation without drowsiness. Unlike conventional sleep inducers, L-theanine is not a sedative but promotes good quality of sleep through anxiolysis. This review suggests that L-theanine is a safe natural sleep aid.

Objectives Widespread sensory deficits resembling hemihypoaesthesia occur in 20-40% of chronic pain patients on the side of pain, independent of pain aetiology, and have been termed nondermatomal sensory deficits (NDSD). Sensory profiles have rarely been investigated in NDSD. Methods Quantitative sensory testing (QST) according to the protocol of the German Research Network on Neuropathic Pain (DFNS) was performed in the face, hand and foot of the painful body side and in contralateral regions in chronic pain patients. Twenty-five patients with NDSD and 23 without NDSD (termed pain-only group) were included after exclusion of neuropathic pain. Comprehensive clinical and psychiatric evaluations were done. Results NDSD in chronic pain was associated with high burden of disease and more widespread pain. Only in the NDSD group significantly higher thresholds for mechanical and painful stimuli were found in at least 2 of 3 regions ipsilateral to pain. In addition, we found a bilateral loss of function for temperature and vibration detection, and a gain of function for pressure pain in certain regions in patients with NDSD. Sensory loss and gain of function for pressure pain correlated with pain intensity in several regions. Discussion This may indicate a distinct sensory profile in chronic non-neuropathic pain and NDSD, probably attributable to altered central pain processing and sensitisation. The presence of NDSD in chronic non-neuropathic pain may be regarded as a marker for higher burden of pain disease. PMID:27841837

The global burden of breast cancer highlights the need for primary prevention strategies that demonstrate both favorable clinical benefit/risk profile and good value for money. Endocrine therapy with selective estrogen-receptor modulators (SERMs) or aromatase inhibitors (AIs) has been associated with a favorable clinical benefit/risk profile in the prevention of breast cancer in women at high risk of developing the disease. The available endocrine therapy strategies differ in terms of their relative reductions of breast cancer risk, potential side effects, and upfront drug acquisition costs, among others. This review highlights the clinical trials of SERMs and AIs for the primary prevention of breast cancer, and the cost-effectiveness /cost-utility studies that have examined their "value for money" in various health care jurisdictions.

Evaluating outcomes of palliative photodynamic therapy: instrument development and preliminary results

Background: Subjective measures are considered the gold standard in palliative care evaluation, but no studies have evaluated palliative photodynamic therapy (PDT) subjectively. If PDT is to be accepted as a palliative therapy for later-stage obstructing esophageal and lung cancer, evidence of its effectiveness and acceptability to patients must be made known. Study Design/Materials and Methods: This ongoing study's major aim is to evaluate subjective outcomes of PDT in patients with obstructing esophageal and lung cancer. Existing measures of health status, dysphagia and performance status were supplemented with an instrument developed to evaluate PDT symptom relief and side effect burden, the PDT Side Effects Survey (PSES). Results: PDT patients treated with porfimer sodium (Photofrin) and 630-nm light experienced reduced dysphagia grade and stable performance status for at least one month after PDT (N= 10-17), but these effects did not necessarily persist at three months. Fatigue, appetite and quality of life may be the most burdensome issues for these patients. Conclusions: Preliminary data suggest that the PSES is an acceptable and valid tool for measuring subjective outcomes of palliative PDT. This study is the first attempt to systematically evaluate subjective outcomes of palliative PDT. Multi-center outcomes research is needed to draw generalizable conclusions that will establish PDT's effectiveness in actual clinical practice and enhance the wider adoption of PDT as a cancer symptom relief modality.

Methadone maintenance therapy (MMT) in China is facing challenges such as high relapse rates and low coverage. The study assessed factors influencing MMT utilization among opiate users. In-depth interviews were conducted among 30 opiate users in 2008 to ascertain the barriers against seeking MMT. Data were analyzed using ATLAS.ti. Barriers to the treatment included requirement of registration with police, perceived discrimination, logistic difficulties, side effects, fear of being addicted to another drug, lack of additional services, and economic burden. The result suggests the need for structural changes such as improving comprehensive services, simplifying application procedure, and enhancing referral system. The study's limitations are noted.

Summary Background L-carnitine was proposed as a potential treatment for patients diagnosed with an autism spectrum disorder to improve mitochondrial dysfunction, but no prior randomized controlled trials have been conducted. Material/Methods Thirty subjects diagnosed with an ASD were randomly assigned to receive a standardized regimen (50 mg L-carnitine/kg bodyweight/day) of liquid L-carnitine (n=19) or placebo (n=11) for 3-months. Measures included changes in professionally completed Childhood Autism Rating Scale (CARS), hand muscle testing, and modified clinical global impression (CGI) forms; parent completed Autism Treatment Evaluation Checklist (ATEC), treatment adherence measurement (TAM), frequency and intensity of side effect rating (FISER)/global rating of side effect burden (GRSEB)/patient report of incidence of side effects (PRISE) forms; and lab testing. Results Significant improvements were observed in CARS (−2.03, 95% CI=−3.7 to −0.31), CGI (−0.69, 95% CI=−1.1 to −0.06), and ATEC scores. Significant correlations between changes in serum free-carnitine levels and positive clinical changes were observed for hand muscle strength (R2=0.23, P=0.046), cognitive scores (R2=0.27, P=0.019), and CARS scores (R2=0.20, P=0.047). Study subjects were protocol-compliant (average adherence was >85%) and generally well-tolerated the L-carnitine therapy given. Conclusions L-carnitine therapy (50 mg/kilogram-bodyweight/day) administered for 3-months significantly improved several clinical measurements of ASD severity, but subsequent studies are recommended.

A study of severance taxes on crude oil and natural gas: The irreversibility of taxation

NASA Astrophysics Data System (ADS)

Brandly, Mark L.

This dissertation examines the institution of severance taxes. An explanation of the property rights allocations in the petroleum industry provides the foundation for discussing the incentive structure of the industry. This explanation concludes that the severance tax burden on the supply side of the industry is born by oil producers and royalty owners. A history of national and state severance taxes in the United States is provided. The literature on the justifications for severance taxes and the economic studies that are relevant to the issue of the tax effect on oil output is reviewed. This review shows that an important implication of severance taxes, the fact that the output effect of such taxes is at least partially irreversible, has been overlooked. A mathematical model is constructed that demonstrates the relationships between output, the sellers' price, the buyers' price, excess burden, the consumers' tax burden, the producers' tax burden, and the price elasticities of supply and demand. It is then demonstrated that the appropriate framework for analyzing severance taxes includes an upward sloping supply curve and a completely elastic demand curve. Another mathematical model shows the effect that a severance tax has on the output decision given different income tax situations. A review of the industry procedures for abandoning wells is followed by a theoretical argument that severance taxes are irreversible to some degree. When a well is abandoned, due to a severance tax, the well is plugged with cement. The costs of reentering such a well are large relative to the potential profits to be derived from such a decision. Eliminating the severance tax does not provide the incentive needed to reenter and produce an abandoned well. An empirical examination of the Kansas severance tax imposed in 1983 compares the present value of an abandoned well with the costs of reentering such a well. This comparison leads to the conclusion that, generally, a well that was abandoned due to this tax would not be reentered if the tax were lifted. Therefore, the tax is highly irreversible.

Major depression is one of the most debilitating diseases in terms of quality of life. Less than half of patients suffering from depression can achieve remission after adequate antidepressant treatment. Another promising treatment option is cognitive-behavior therapy (CBT). However, the need for experienced therapists and substantive dedicated time prevent CBT from being widely disseminated. In the present study, we aim to examine the effectiveness of switching antidepressants and starting a smartphone-based CBT program at the same time, in comparison to switching antidepressants only, among patients still suffering from depression after adequate antidepressant treatment. A multi-center randomized trial is currently being conducted since September 2014. The smartphone-based CBT program, named the "Kokoro-App," for major depression has been developed and its feasibility has been confirmed in a previous open study. The program consists of an introduction, 6 sessions and an epilogue, and is expected to be completed within 9 weeks by patients. In the present trial, 164 patients with DSM-5 major depressive disorder and still suffering from depressive symptoms after adequate antidepressant treatment for more than 4 weeks will be allocated to the Kokoro-App plus switching antidepressant group or the switching antidepressant alone group. The participants allocated to the latter group will receive full components of the Kokoro-App after 9 weeks. The primary outcome is the change in the total score on the Patient Health Questionnaire through the 9 weeks of the program, as assessed at week 0, 1, 5 and 9 via telephone by blinded raters. The secondary outcomes include the change in the total score of the Beck Depression Inventory-II, change in side effects as assessed by the Frequency, Intensity and Burden of Side Effects Rating, and treatment satisfaction. An effective and reachable intervention may not only lead to healthier mental status among depressed patients, but also to reduced social burden from this illness. This paper outlines the background and methods of a trial that evaluates the possible additive value of a smartphone-based CBT program for treatment-resistant depression.

Alternative Therapies for Diabetes: A Comparison of Western and Traditional Chinese Medicine (TCM) Approaches.

PubMed

Xiao, Eric; Luo, Luguang

2017-05-18

Across the world, the economic and health costs of diabetes are rising at an alarming rate. Each year in the United States, billions of dollars are spent on T2 Diabetes mellitus (T2DM) treatments, but such treatments are not always effective and can lead to adverse events. Many pharmacological treatments exist to control the primary and secondary symptoms of T2DM, but these medications are not always efficacious, do little to treat secondary T2DM symptoms, and often carry adverse side effects. Traditional Chinese Medicine (TCM) is a form of alternative medicine that is becoming appealing to western healthcare systems because of its comprehensive, holistic approach to managing T2DM patients. Works across TCM printed texts, clinical trial databases, medical association practice guidelines, and the existing literature on TCM and western diabetes treatments (in print and online) are reviewed. Conventional pharmaceutical therapies for T2DM are not efficacious enough to maintain satisfactory blood glucose levels for all patients, and even patients who maintain stable blood glucose levels may still suffer from secondary T2DM symptoms as well as from the side effects of their medications. TCM therapies have demonstrated promising results in T2DM clinical studies without causing the types of side effects associated with standard pharmaceutical treatments. In addition, the economic burden of TCM diabetes treatments on patients and payers is oftentimes less than that of pharmaceutical regimens. TCM approaches can be a viable alternative approach to treatment in the modern U.S. healthcare landscape, but a number of obstacles impede its assimilation into western health systems.

Effects of isradipine and other calcium antagonists on arteriovenous-shunt flow in anesthetized rabbits and cats

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hof, R.P.

The effects of vasodilators on arteriovenous (AV)-shunt flow was investigated in anesthetized cats and rabbits, using the tracer microsphere method. In cats, the calcium antagonist isradipine reduced AV-shunt flow; verapamil showed a similar tendency and nicardipine was without effect. Dihydralazine strongly increased, but nitroglycerin and dipyridamole decreased AV-shunt flow. In rabbits, the effects of isradipine and verapamil were similar to those seen in cats. Sodium nitroprusside had no effect, whereas prazosin, minoxidil, and the potassium-channel activator cromakalim increased AV-shunt flow. The contrasting effects of drugs sharing the same mechanism of action suggest that target-tissue selectivity is more important than themore » mechanism of action. An increase of AV-shunt flow is unlikely to be beneficial but could be associated with a number of undesirable side effects. It might negatively affect migraine sufferers and, if AV-shunt dilatation shows no tolerance development, it represents an unnecessary hemodynamic burden for the heart.« less

Nanomedicine as an emerging approach against intracellular pathogens

PubMed Central

Armstead, Andrea L; Li, Bingyun

2011-01-01

Diseases such as tuberculosis, hepatitis, and HIV/AIDS are caused by intracellular pathogens and are a major burden to the global medical community. Conventional treatments for these diseases typically consist of long-term therapy with a combination of drugs, which may lead to side effects and contribute to low patient compliance. The pathogens reside within intracellular compartments of the cell, which provide additional barriers to effective treatment. Therefore, there is a need for improved and more effective therapies for such intracellular diseases. This review will summarize, for the first time, the intracellular compartments in which pathogens can reside and discuss how nanomedicine has the potential to improve intracellular disease therapy by offering properties such as targeting, sustained drug release, and drug delivery to the pathogen’s intracellular location. The characteristics of nanomedicine may prove advantageous in developing improved or alternative therapies for intracellular diseases. PMID:22228996

Trazodone Addition to Paroxetine and Mirtazapine in a Patient with Treatment-Resistant Depression: The Pros and Cons of Combining Three Antidepressants

PubMed Central

Alves, José Carlos; Rego, Raquel Garcia

2016-01-01

Dual antidepressant combination for treatment-resistant depression is a strategy well supported by literature and accepted in clinical practice. Rather, the usefulness of the combination of more than two antidepressants is controversial. This may be related to the possibility of higher side-effect burden and to doubts about its pharmacological effectiveness and therapeutic advantage compared to other standard treatment options. We report a relapse of moderate-to-severe depressive symptoms with insomnia that successfully remitted after the addition of trazodone to a dual combination of paroxetine and mirtazapine (in standard effective doses) in a patient with treatment-resistant depression. We also review the literature and discuss the utility of triple antidepressant combination in treatment-resistant depression. This clinical case highlights the utility of combining trazodone as a third antidepressant for the relapse of depressive symptoms after the failure of a dual antidepressant combination. Trazodone may be advantageous in patients presenting recurrence of moderate-to-severe depressive symptoms that include sleep problems and/or insomnia and may be particularly useful when benzodiazepines are not recommended. Although its use may be controversial and associated with higher risk of side-effects, more investigation is needed to determine the efficacy and safety for triple antidepressant combinations as reliable strategies for treatment-resistant depression in clinical practice.

Mevalonate kinase deficiency (MKD) is a hereditary autoinflammatory syndrome marked by recurrent attacks of fever and inflammation. Severe enzyme deficiency results in mevalonic aciduria (MA) and milder deficiency in hyperimmunoglobulin D syndrome (HIDS). Treatment remains a challenge. To observe the effect of the recombinant interleukin-1 receptor antagonist anakinra in patients with MKD. A prospective observational study was undertaken. Two patients with MA started continuous treatment with anakinra (1-2 mg/kg/day) and nine patients with HIDS chose between continuous treatment and on-demand treatment (starting at first symptoms of attack, 100 mg/day or 1 mg/kg/day for 5-7 days). Anakinra induced partial remission in one patient with MA but there was no response in the other patient with MA. In one patient with HIDS continuous treatment induced complete remission for 7 months but was stopped because of side effects. Eight patients with HIDS preferred on-demand treatment from the start. This induced a clinical response (≥50% reduction in duration) in 8 of 12 treated attacks without a change in attack frequency. Anakinra prevented fever attacks due to vaccination without inhibiting antibody induction. No major side effects were seen. On-demand treatment with anakinra in HIDS decreases the duration and severity of fever attacks. Because of the burden of daily injections and relatively long asymptomatic intervals of HIDS, all patients with HIDS preferred on-demand treatment.

OBJECTIVE To assess disease burden of chemotherapy-induced peripheral neuropathy (CIPN), which is a common dose-limiting side-effect of neurotoxic chemotherapy. Late effects of CIPN may increase with improved cancer survival. METHODS Olmsted County, Minnesota residents receiving neurotoxic chemotherapy were identified and CIPN was ascertained via text searches of polyneuropathy symptoms in the medical record. Clinical records were queried to collect data on baseline characteristics, risk factors, signs and symptoms of CIPN, medications, impairments, and ICD-9 diagnostic codes for all subjects. RESULTS A total of 509 individuals with incident exposure to an inclusive list of neurotoxic chemotherapy agents between 2006 and 2008 were identified. 268 (52.7%) of these individuals were determined to have CIPN. The median time from incident exposure to first documented symptoms was 71 days. Patients with CIPN received a neuropathy ICD-9 diagnosis in only 37 instances (13.8%). Pain symptoms and use of pain medications were observed more often in patients with CIPN. 5-year survival was greater in those with CIPN (55.2%) versus those without (36.1%). Those with CIPN surviving greater than 5 years (n=145) continued to have substantial impairments and were more likely to be prescribed opioids than those without CIPN (OR 2.0, 1.06–3.69). CONCLUSIONS Results from our population-based study are consistent with previous reports of high incidence of CIPN in the first two years following incident exposure to neurotoxic chemotherapeutic agents, and its association with significant pain symptomatology and accompanied long-term opioid use. Increased survival following exposure to neurotoxic chemotherapy and its long-term disease burden necessitates further study of among survivors. PMID:29439162

Schmid, R; Spiessl, H; Cording, C

2005-12-01

The purpose of this article is to provide an overview of the current research regarding the situation of mentally ill persons. The relevant literature was identified by means of a computerized MEDLINE search on the years 1996 - 2004 with the key words "sibling" and "mentally ill"/"chronically ill"/"psychiatric disorder" (631 articles). Also the related articles in the MEDLINE search were viewed. Finally 170 articles of journals and books were included in the review. The situation of siblings of psychiatric ill has manifold aspects, which can be classified into the following categories: Burdens due to the relationship to the ill sibling, burdens because of the relations to the shared parents and other family members, and burdens in the daily life of the siblings due to the illness of his/her sibling. On the other side there are rewards and positive developments in their life because of the illness of the sibling. Personal variables like sex, family size and age at onset of the illness are an influence on the experience of the sibling. The revealed burdens of the affected siblings require necessary answers by political representatives, professionals in and outside a clinic, and the involved families.

Kidney transplantation offers improved survival and quality of life to an increasing number of elderly patients with end-stage kidney disease. However, elderly kidney transplant recipients may face unique challenges due to a higher burden of comorbidity, greater cumulative risk of immunosuppression-related complications and increasing frailty. We aimed to describe the perspectives of elderly kidney transplant recipients. Electronic databases were searched to April 2015. Qualitative studies were eligible if they reported views from elderly kidney transplant recipients (≥60 years). Thematic synthesis was used to analyse the findings. Twenty-one studies involving >116 recipients were included. We identified seven themes. 'Regaining strength and vitality' meant valuing the physical and psychosocial improvements in daily functioning and life participation. 'Extending life' was the willingness to accept any organ, including extended criteria kidneys, to prolong survival. 'Debt of gratitude' entailed conscious appreciation toward their donor while knowing they were unable to repay their sacrifice. 'Moral responsibility to maintain health' motivated adherence to medication and lifestyle recommendations out of an ethical duty to protect their gift for graft survival. 'Unabating and worsening forgetfulness' hindered self-management. 'Disillusionment with side effects and complications' reflected disappointment and exasperation with the unintended consequences of medications. 'Finality of treatment option' was an acute awareness that the current transplant may be their last. Kidney transplantation was perceived to slow and even reverse the experience of aging among elderly recipients, especially compared with dialysis. However, some were frustrated over persistent limitations after transplant, struggled with the burden of medication side effects and worried about a possible return to dialysis if the transplant failed. Clarifying patient expectations of transplantation, providing support to alleviate the debilitating impacts of immunosuppression and addressing fears about deteriorating health and graft failure may improve satisfaction and outcomes in elderly kidney transplant recipients. © The Author 2016.

Major depressive disorder (MDD) significantly impacts performance of both work- and nonwork-related routine daily activities. We have shown that work productivity is significantly impaired in employed MDD patients, but the extent of impairments in nonwork-related routine activities and its association with antidepressant treatment outcomes has not been established. Activity impairment was measured using the sixth item of Work Productivity and Activity Impairment Scale in the Combining Medications to Enhance Depression Outcomes (CO-MED) trial (n=665). Published norms were used to define activity impairment levels. The relationship between activity impairment and baseline sociodemographic and clinical characteristics was evaluated along with changes in activity impairment and its relationship with other clinical outcomes such as symptom severity, function, and side effect burden. Remission status at 3 and 7 months was predicted based on week 6 activity impairment level. Higher psychosocial and cognitive impairments and greater number of comorbid medical conditions were associated with greater activity impairment at baseline. Proportion of participants with severe activity impairment declined from 47.6% at baseline to 18.7% at 3 months, while mean activity impairment decreased from 57.1 at baseline to 32.8 at 3 months. During course of treatment, levels of activity impairment correlated most strongly with psychosocial function among measures of symptom severity, function, quality of life, and side effect burden. No or minimal activity impairment at week 6 was associated with two to three times higher rates of remission at 3 and 7 months as compared to moderate or severe activity impairment levels even after controlling for remission status at week 6 and select baseline variables. Depressed patients have high levels of nonwork-related activity impairment at baseline that improves significantly with treatment and independently predicts long-term clinical outcomes. Brief systematic assessment of activity impairment during the course of antidepressant treatment can help inform clinical decision-making.

The aims of this study were (1) to compare health outcomes (i.e., health-related quality of life [HRQoL], productivity at work, and healthcare resource use visits) between those with insomnia and non-insomnia controls, (2) to compare health outcomes between those treated for insomnia and non-insomnia controls, and (3) to assess the prevalence of side effects of insomnia medications and their relationship with health outcomes. Data from the 2013 US (N = 75,000) and 5EU (N = 62,000) National Health and Wellness Survey (NHWS) were used. The NHWS is a patient-reported survey administered to a demographically representative sample of adults. Those who met DSM-V criteria for insomnia and, separately, those treated for insomnia were compared with equivalently sized control groups who were identified using a propensity score matching method. Outcomes included HRQoL (Short Form 36v2), productivity at work (Work Productivity and Activity Impairment—General Health questionnaire), and healthcare resource use visits in the past 6 months and were analyzed using one-way ANOVAs. Among those with treated insomnia, those with and without side effects were compared on health outcomes using general linear models controlling for confounding variables. Patients with insomnia (n = 4147) and treated insomnia (n = 2860) in the 5EU reported significantly worse HRQoL than controls (health utilities: 0.60 vs. 0.74; 0.60 vs. 0.74, respectively), greater overall work impairment (38.74% vs. 14.86%; 39.50% vs. 15.66%), and more physician visits in the past 6 months (9.10 vs. 4.08; 9.58 vs. 4.11). Similar findings were observed in the US. Among those treated for insomnia, 13.56% and 24.55% in the US and 5EU, respectively, were non-adherent due to side effects. In the US, non-adherence was associated with significantly worse HRQoL (health utilities: 0.60 vs. 0.64, p <.05) and greater overall work impairment (37.71% vs. 29.08%, p <.05), among other significant differences. These relationships were not significant in the 5EU. A significant burden of insomnia was observed in both the US and 5EU, and the association remained even after treatment. Non-adherence due to side effects was common and, in the case of the US, associated with significantly poorer health outcomes. PMID:26426805

Non-use of the walker may be secondary to an initial inappropriate prescribing, a lack of adequate training, a lack of monitoring and side effects of using. Improving both stability and mobility in users is due to several biomechanical mechanisms. The benefits of walker are: general physiological effects, more confidence, better social life and decrease in the burden of care. The disadvantages of walker are: technical or practical aspects criticized by users, musculoskeletal disorders, delayed reaction time, fall risk and stigma. Few scientific data evaluating the interest of the walker concerning mobility exist, thus recommendations are low grade and are often taken from professional clinical experiences. The choice of technical walking assistance depends on the pathology and biomechanical mechanism. The walker robots are few distributed. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Colorectal cancer is a significant source of morbidity and mortality in the United States and other Western countries. Oral delivery of therapeutics remains the most patient accepted form of medication. The development of an oral delivery formulation for local delivery of chemotherapeutics in the gastrointestinal tract can potentially alleviate the adverse side effects including systemic cytotoxicity, as well as focus therapy to the lesions. Here we develop an oral formulation of the chemotherapeutic drug oxaliplatin for the treatment of colorectal cancer. Oxaliplatin was encapsulated in pH sensitive, mucoadhesive chitosan-coated alginate microspheres. The microparticles were formulated to release the chemotherapeutics after passing through the acidic gastric environment thus targeting the intestinal tract. In vivo, these particles substantially reduced the tumor burden in an orthotopic mouse model of colorectal cancer, and reduced mortality. PMID:22472433

Tongue-in-groove (TIG) is a conservative but powerful surgical suture technique to control shape, rotation, and projection of the nasal tip. In this study, statistical analyses were performed to determine the aesthetical and functional effectiveness of TIG rhinoplasty. Prospective cohort study including 110 Caucasian or Mediterranean aesthetic rhinoplasty patients treated by one surgeon between 2007 and 2012, with a 1-year follow-up. Data were collected using the Utrecht Questionnaire, a validated instrument routinely offered to our patients before and 1 year after surgery. Aesthetic results were reflected by change in subjective body image in relation to nasal appearance, scored on five aesthetic questions and a 10-cm visual analog scale (VAS). Functional results were determined by change in subjective nasal airway patency, scored on a 10-cm VAS for both sides. The mean aesthetic sum score (5, low burden-25, high burden) significantly improved from 14.01 to 6.54 (P <.01). The mean aesthetic VAS score (0, very ugly-10, very nice) significantly improved from 3.35 to 7.78 (P < .01). The mean functional VAS score (0, very bad-10, very good) showed a small but significant improvement on both sides (left, 6.83-7.96; right, 6.88-7.80; P <.01). Statistical analysis of quantified subjective data on nasal aesthetics and function show that TIG is a reliable technique that can help to deliver consistently good results in Caucasian and Mediterranean patients seeking aesthetic rhinoplasty. A small additional functional improvement can be expected. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

The purpose of this study was to investigate the impact of caregivers' appraisals of the effectiveness of their own communication strategies on caregiver burden when caring for family members with Alzheimer's disease (AD). Family caregivers (N = 84) of participants with AD completed questionnaires appraising communication strategies, problem behaviors, and levels of three types of burden. Hierarchical linear regression models revealed that effective strategies and kinship status were significantly linked with stress burden, whereas effective strategies and problem behaviors were significantly related to relationship burden. Cognitive status of participants with AD significantly predicted objective burden. Caregivers who rated effective strategies as helpful were more likely to experience lower levels of stress and relationship burden. Findings provide preliminary support for understanding mechanisms by which the appraisals of communication strategies influence caregiver burden and justify testing empirically derived communication interventions.

Physiological remodeling of bifurcation aneurysms: preclinical results of the eCLIPs device.

2018-02-01

OBJECTIVE Intracranial bifurcation aneurysms are complex lesions for which current therapy, including simple coiling, balloon- or stent-assisted coiling, coil retention, or intrasaccular devices, is inadequate. Thromboembolic complications due to a large burden of intraluminal metal, impedance of access to side branches, and a high recurrence rate, due largely to the unmitigated high-pressure flow into the aneurysm (water hammer effect), are among the limitations imposed by current therapy. The authors describe herein a novel device, eCLIPs, and its use in a preclinical laboratory study that suggests the device's design and functional features may overcome many of these limitations. METHODS A preclinical model of wide-necked bifurcation aneurysms in rabbits was used to assess functional features and efficacy of aneurysm occlusion by the eCLIPs device. RESULTS The eCLIPs device, in bridging the aneurysm neck, allows coil retention, disrupts flow away from the aneurysm, leaves the main vessel and side branches unencumbered by intraluminal metal, and serves as a platform for endothelial growth across the neck, excluding the aneurysm from the circulation. CONCLUSIONS The eCLIPs device permits physiological remodeling of the bifurcation.

[Thinking from the end - Does the diagnosis "cancer" make a difference to patients and carers?].

PubMed

Bausewein, Claudia

2013-01-01

The diagnosis of cancer is often associated with pain, suffering and dying. Many of these aspects also apply to patients dying from non-malignant disease. Being confronted with a malignancy posts an existential threat for many patients that is linked with loss of control, challenge of autonomy and fear of the future. In contrast, patients with non-malignant disease do not realise the scope of their diagnosis and the potentially life-limiting nature of their disease. The prognosis of patients with chronic organ failure is often shorter than that of some patients with malignancies. Patients with malignant and non-malignant disease suffer from pain and many other symptoms. Tumour-oriented therapies, side effects and changes of the body image add to the suffering of cancer patients. Although consequences of the disease and the therapies are often not visible in patients with non-malignant disease, the increasing functional decline, psychosocial burden, lack of co-ordination of care, and information needs burden patients. Wishes at the end of life are similar in cancer and non-cancer patients. Access to palliative care is much easier for cancer patients than for non-cancer patients. Copyright © 2013.

Every innovation assumes, however, that the advantages and disadvantages, potential complications, and burden to the patient have been weighed against those of conventional methods. The risks that a pioneer takes must be justified and presented comprehensively and clearly to the patient. Otherwise the threat is posed of civil and criminal accusations of negligence in responsibility or in the obligation to fully inform patients.

2015-08-01

There are over 100 different types of arthritis and each can differ greatly in their aetiology and pathophysiology; however, one characteristic that is common to all arthritic conditions is joint pain. Musculoskeletal pain is the leading cause of disability in the world, and the number one reason arthritis patients visit their primary care physician. Despite the prevalence and burden of arthritis pain, current analgesics lack sufficient efficacy and are plagued by multiple adverse side effects. In this review, we outline the current landscape of research concerning joint pain, drawing from both preclinical and clinical studies. Specifically, this review is a discussion of the different neurophysiological processes that occur during joint disease and how inflammatory and neuropathic aspects contribute to the development of arthritis pain.

Intranasal ipratropium bromide for the common cold.

2011-07-06

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects were reported as a secondary outcome. We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2011, Issue 1) which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE (1950 to January week 4, 2011), MEDLINE in-process and other non-indexed citations (February 2011), EMBASE (1974 to February 2011), AMED (1985 to February 2011), Biosis (1974 to February 2011) and LILACS (1985 to February 2011). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well-tolerated and self-limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

Non-adherence to tuberculosis therapy can lead to drug resistance, prolonged infectiousness, and death; therefore, understanding what causes treatment default is important. Pakistan has one of the highest burdens of tuberculosis in the world, yet there have been no qualitative studies in Pakistan that have specifically examined why default occurs. We conducted a mixed methods study at a tuberculosis clinic in Karachi to understand why patients with drug-susceptible tuberculosis default from treatment, and to identify factors associated with default. Patients attending this clinic pick up medications weekly and undergo family-supported directly observed therapy. In-depth interviews were administered to 21 patients who had defaulted. We also compared patients who defaulted with those who were cured, had completed, or had failed treatment in 2013. Qualitative analyses showed the most common reasons for default were the financial burden of treatment, and medication side effects and beliefs. The influence of finances on other causes of default was also prominent, as was concern about the effect of treatment on family members. In quantitative analysis, of 2120 patients, 301 (14.2%) defaulted. Univariate analysis found that male gender (OR: 1.34, 95% CI: 1.04-1.71), being 35-59 years of age (OR: 1.54, 95% CI: 1.14-2.08), or being 60 years of age or older (OR: 1.84, 95% CI: 1.17-2.88) were associated with default. After adjusting for gender, disease site, and patient category, being 35-59 years of age (aOR: 1.49, 95% CI: 1.10-2.03) or 60 years of age or older (aOR: 1.76, 95% CI: 1.12-2.77) were associated with default. In multivariate analysis age was the only variable associated with default. This lack of identifiable risk factors and our qualitative findings imply that default is complex and often due to extrinsic and medication-related factors. More tolerable medications, improved side effect management, and innovative cost-reduction measures are needed to reduce default from tuberculosis treatment.

Visceral pain is the most common form of pain caused by varied diseases and a major reason for patients to seek medical consultation. It also leads to a significant economic burden due to workdays lost and reduced productivity. Further, long-term use of non-specific medications is also associated with side effects affecting the quality of life. Despite years of extensive research and the availability of several therapeutic options, management of patients with chronic visceral pain is often inadequate, resulting in frustration for both patients and physicians. This is, most likely, because the mechanisms associated with chronic visceral pain are different from those of acute pain. Accumulating evidence from years of research implicates several receptors and ion channels in the induction and maintenance of central and peripheral sensitization during chronic pain states. Understanding the specific role of these receptors will facilitate to capitalize on their unique properties to augment the therapeutic efficacy while at the same time minimizing unwanted side effects. The aim of this review is to provide a concise review of the recent literature that reports on the role of principal ionotropic receptors and metabotropic receptors in the modulation visceral pain. We also include an overview of the possibility of these receptors as potential new targets for the treatment of chronic visceral pain conditions. PMID:25843070

Purpose: Essential thrombocythemia, polycythemia vera, and myelofibrosis are rare chronic hematological malignancies known as myeloproliferative neoplasms (MPNs) and are characterized by deregulated myeloid lineage cell production, splenomegaly, and heterogeneous symptom profiles. MPN patients suffer from a significant symptom burden (eg, fatigue, depressive symptoms, early satiety) and an impaired overall quality of life (QoL). Current treatments typically include pharmacological approaches, which may come with additional side effects and may be limited by treatment-associated toxicities (ie, cytopenias). Nonpharmacological approaches such as physical activity may be beneficial for reducing symptom burden and improving QoL. To date, no studies have examined physical activity as a nonpharmacological approach in MPN patients despite preliminary evidence supporting its benefit in other hematological cancers. The purpose of this article is to (1) review the literature related to physical activity and specific hematological cancer subtypes and to (2) make suggestions for future research involving physical activity in MPN patients as a symptom management strategy. Methods: A brief review of studies examining physical activity in leukemias, lymphomas, and myelomas (excluding stem-cell transplant patients) was conducted. Results: There is preliminary evidence to suggest that physical activity may be an effective approach to improve patient-reported outcomes (fatigue, depression, anxiety, sleep), physical fitness (cardiovascular fitness, balance, body composition), and overall QoL in other hematological cancers. Conclusions: Based on encouraging findings in other hematological cancers, future research should examine the feasibility and effectiveness of physical activity in MPN patients. PMID:27458250

Abstract Rationale: Hypertriglyceridemia is defined as a level of triglycerides above 150 mg/dL. The complex causes and classification of hypertriglyceridemia lead to difficulties in the diagnosis and management of this condition. Patient concerns: We present the case of a 15 years and 6 months old female teenager, admitted in our clinic for the following complaints: severe abdominal pain predominantly in the lateral left quadrant, nausea, vomiting, and the lack of stools for 2 days. The clinical exam showed: impaired general status, painful abdomen at superficial and deep palpation in the left and upper abdominal quadrants, the absence of stools for 2 days. Diagnoses: The laboratory parameters revealed leukocytosis with neutrophilia, thrombocytopenia, high level of serum amylase and triglycerides, and increased inflammatory biomarkers. The imagistic investigations showed ascites and paralytic ileus. Interventions: The management was burdened by the side-effects of hypolipidemic drugs impairing the liver function and leading to rhabdomyolysis, but eventually the patient's outcome was good. Outcomes: Type V hyperlipoproteinemia is a rare condition accounting for approximately 5% of the cases. The risk for acute pancreatitis is well-known to be associated with hypertriglyceridemia, even though in rare cases. Lessons: The prognosis of hypertriglyceridemia is pediatrics is burdened not only by the long-term risk factors associated to the diseases itself, but also by the negative effects of long-term hypolipidemic treatment.

Curcumin, a polyphenol derived from the rhizome turmeric, has potential as an anticancer agent. We synthesized an amphipathic/surfactant pegylated curcumin (curcumin-PEG) designed for parenteral administration. Objectives of these investigations were to assess side-effects of a therapeutic regimen of curcumin-PEG in a preclinical model. Intraperitoneal (ip) tumor burdens were reduced in athymic female mice grafted with human SKOV-3 ovarian adenocarcinoma cells and injected intravenously (iv) with curcumin-PEG. There were no gross anatomical or histopathological effects detected in non-reproductive organs. Uteri (luminal fluid imbibition) and ovaries (decreased folliculogenesis) were affected by treatment. Curcumin-PEG ip hastened the onset of puberty in immature female mice. Live births were reduced in mature females housed with males and treated iv with curcumin-PEG; mating (vaginal plugs) was not affected. Accessory gland weights, testicular testosterone concentrations, and spermatogenesis were diminished in mature male mice following iv curcumin-PEG. Estrogenic/antiandrogenic and pregnancy-disrupting effects of a water soluble/bioavailable curcumin were demonstrated. Copyright © 2012 Elsevier Inc. All rights reserved.

Striving for more good days: patient perspectives on botulinum toxin for the treatment of cervical dystonia

2016-01-01

Background The recommended reinjection interval for botulinum neurotoxin (BoNT) formulations in the treatment of cervical dystonia (CD) is generally ≥12 weeks, though intervals ≥10 weeks are approved for incobotulinumtoxinA in Europe. However, recurring symptoms can occur before the end of this period. Using qualitative research, we sought a greater understanding of disease burden, unmet patient needs, and barriers to treatment. Methods We conducted online semistructured, focus-group discussions, and online forum follow-up discussions among patients with CD, focusing on disease burden, patient needs, injection cycle preferences, and relationships with health care professionals. A subset of patients was also questioned in telephone interviews about individual experiences of CD and BoNT treatment. All participants were UK residents who had received onabotulinumtoxinA or abobotulinumtoxinA for CD for ≥1 year. Results Thirty-one patients (81% female; mean duration of CD 16.4 [range 4–31] years; mean BoNT injection cycle length 12.8 weeks) participated in the online focus-group and forum follow-up discussions. Of these, seven patients participated in telephone interviews. All had recurring symptoms between treatments, which substantially impacted on their work, family, and social life. Symptom severity fluctuated throughout an injection cycle and differed between patients and across injection cycles. Participants’ relationships with health care professionals and treatment satisfaction varied greatly. Many participants wanted longer-lasting and/or more stable symptom relief with shorter and/or more flexible injection intervals, according to individual needs. Lack of health care resources, long journeys to treatment centers, and immunogenicity/side-effect concerns were perceived as the main barriers to more flexible treatment. Conclusion The high burden of recurring primary and secondary symptoms of CD considerably affects patients’ quality of life. Patient-led assessments of disease burden revealed that personalized, more flexible, and/or shorter BoNT injection intervals may reduce the day-to-day impact of CD. Collaboration between patients, clinicians, and health care systems may effect change and improve treatment for patients with CD. PMID:27578965

The industrialization of the agricultural sector has increased the chemical burden on natural ecosystems. Pesticides are agrochemicals used in agricultural lands, public health programs, and urban green areas in order to protect plants and humans from various diseases. However, due to their known ability to cause a large number of negative health and environmental effects, their side effects can be an important environmental health risk factor. The urgent need for a more sustainable and ecological approach has produced many innovative ideas, among them agriculture reforms and food production implementing sustainable practice evolving to food sovereignty. It is more obvious than ever that the society needs the implementation of a new agricultural concept regarding food production, which is safer for man and the environment, and to this end, steps such as the declaration of Nyéléni have been taken.

Skin cancer is a major health problem worldwide. It is the most common cancer in the United States and poses a significant healthcare burden. Excessive UVR exposure is the most common cause of skin cancer. Despite various precautionary measures to avoid direct UVR exposure, the incidence of skin cancer and mortality related to it remains high. Furthermore, the current treatment options are expensive and have side effects including toxicity to normal cells. Thus, a safe and effective approach is needed to prevent and treat skin cancer. Chemopreventive strategy using naturally occurring compounds, such as resveratrol, is a promising approach to reduce the incidence of UVR-induced skin cancer and delay its progression. This review highlights the current body of evidence related to chemopreventive role of resveratrol and its molecular mechanisms in UVR-induced skin carcinogenesis. © 2017 John Wiley & Sons A/S.

Thirty years after the discovery of HIV and 15 years since the advent of Highly Active Antiretroviral Therapy (HAART), the features of HIV infection have evolved and need a new approach, which is both more comprehensive and specialized. Indeed, the burden of a chronic disease with multiple determining features has replaced the rapidly fatal infection of the past, which was almost exclusively related to the effects of immunosuppression. Physicians have to be concerned with "new risks" associated with treatment side effects; the consequences of ongoing inflammation and ageing of the HIV-infected population. These include metabolic, cardiovascular, neurocognitive and renal disease as well as lipodystrophy and malignancy. Antiretroviral treatment has been a major step forward, subject to accessibility, tolerance and adherence, but it has not solved all the problems associated with this infection, as it becomes a chronic illness.

Chagas' disease, caused by the protozoan parasite Trypanosoma cruzi, is the most common cause of cardiac-related deaths in endemic regions of Latin America. There is an urgent need for new safer treatments because current standard therapeutic options, benznidazole and nifurtimox, have significant side effects and are only effective in the acute phase of the infection with limited efficacy in the chronic phase. Phenotypic high content screening against the intracellular parasite in infected VERO cells was used to identify a novel hit series of 5-amino-1,2,3-triazole-4-carboxamides (ATC). Optimization of the ATC series gave improvements in potency, aqueous solubility, and metabolic stability, which combined to give significant improvements in oral exposure. Mitigation of a potential Ames and hERG liability ultimately led to two promising compounds, one of which demonstrated significant suppression of parasite burden in a mouse model of Chagas' disease.

Alzheimer's Disease and Exercise: A Literature Review.

PubMed

Cass, Shane P

Alzheimer's disease (AD) is a progressive neurodegenerative disease that impairs memory and cognitive judgment. It is the leading cause of dementia in late adult life and is associated with a significant social burden and increased morbidity and mortality in the elderly. Because of mixed effectiveness of medications, exercise has been considered as a treatment for pre-clinical AD, late stage AD, and as a prevention strategy. Exercise appears to improve brain blood flow, increase hippocampal volume, and improve neurogenesis. Prospective studies indicate that physical inactivity is one of the most common preventable risk factors for developing AD and that higher physical activity levels are associated with a reduced risk of development of disease. Exercise as a treatment for AD shows improvement in cognitive function, decreased neuropsychiatric symptoms, and a slower decline in activities of daily living (ADL). Exercise has been shown to have fewer side effects and better adherence compared to medications.

Both all-trans retinoic acid (ATRA) and arsenic trioxide (As(2)O(3)) have proven to be very effective in obtaining high clinical complete remission (CR) rates in acute promyelocytic leukemia (APL). In this study, 73 newly diagnosed APL subjects were treated with an ATRA and As(2)O(3) combination treatment in remission induction and post remission therapy. Tumor burden was examined with PCR of the PML-RAR fusion transcripts, and side effects were evaluated by means of clinical examination. The results showed that ATRA/As(2)O(3) combination therapy yielded a CR rate of 94.5% (69/73) with a shorter time to enter CR (median: 27 days; range: 21-43 days). Four cases failed to enter CR; three of these died of cerebral hemorrhage and disseminated intravascular coagulation (DIC) within 72 hours of starting induction therapy, one older patient died of severe pulmonary infection. The early death rate was 5.5% (4/73). All 69 cases that obtained CR remained in good clinical remission after a follow-up of 35-74 months (median: 52 months).The drug toxicity profile with the use of As(2)O(3) showed mainly hepatotoxicity. Liver dysfunction was slight in most cases. There were no severe side effects in long term follow-up. We conclude that APL patients may benefit from the use of the combination of ATRA and As(2)O(3) in either remission induction or consolidation/maintenance.

Measurement of prostate tumour volume can inform prognosis and treatment selection, including an assessment of the suitability and feasibility of focal therapy, which can potentially spare patients the deleterious side effects of radical treatment. Prostate biopsy is the clinical standard for diagnosis but provides limited information regarding tumour volume due to sparse tissue sampling. A non-invasive means for accurate determination of tumour burden could be of clinical value and an important step toward reduction of overtreatment. Multi-parametric magnetic resonance imaging (MPMRI) is showing promise for prostate cancer diagnosis. However, the accuracy and inter-observer variability of prostate tumour volume estimation based on separate expert contouring of T2-weighted (T2W), dynamic contrastenhanced (DCE), and diffusion-weighted (DW) MRI sequences acquired using an endorectal coil at 3T is currently unknown. We investigated this question using a histologic reference standard based on a highly accurate MPMRIhistology image registration and a smooth interpolation of planimetric tumour measurements on histology. Our results showed that prostate tumour volumes estimated based on MPMRI consistently overestimated histological reference tumour volumes. The variability of tumour volume estimates across the different pulse sequences exceeded interobserver variability within any sequence. Tumour volume estimates on DCE MRI provided the lowest inter-observer variability and the highest correlation with histology tumour volumes, whereas the apparent diffusion coefficient (ADC) maps provided the lowest volume estimation error. If validated on a larger data set, the observed correlations could support the development of automated prostate tumour volume segmentation algorithms as well as correction schemes for tumour burden estimation on MPMRI.

Thyroid hormone analogs for the treatment of dyslipidemia: past, present, and future.

Treatment of dyslipidemia is a major burden for public health. Thyroid hormone regulates lipid metabolism by binding the thyroid hormone receptor (TR), but the use of thyroid hormone to treat dyslipidemia is not indicated due to its deleterious effects on heart, bone, and muscle. Thyroid hormone analogs have been conceived to selectively activate TR in the liver, thus reducing potential side-effects. The authors searched the PubMed database to review TR and the action of thyromimetics in vitro and in animal models. Then, all double-blind, placebo controlled trials that analyzed the use of thyroid hormone analog for the treatment of dyslipidemia in humans were included. Finally, the ongoing research on the use of TR agonists was searched, searching the US National Institutes of Health Registry and the WHO International Clinical Trial Registry Platform (ICTRP). Thyromimetics were tested in humans for the treatment of dyslipidemia, as a single therapeutic agent or as an add-on therapy to the traditional lipid-lowering drugs. In most trials, thyromimetics lowered total cholesterol, low-density lipoprotein cholesterol, and triglycerides, but their use has been associated with adverse side-effects, both in pre-clinical studies and in humans. The use of thyromimetics for the treatment of dyslipidemia is not presently recommended. Future possible clinical applications might include their use to promote weight reduction. Thyromimetics might also represent an interesting alternative, both for the treatment of non-alcoholic steatohepatitis, and type 2 diabetes due to their positive effects on insulin sensitivity. Finally, additional experimental and clinical studies are needed for a better comprehension of the effect(s) of a long-term therapy.

The financial burden of childhood cancer may contribute to the distress that parents experience during and after treatment. Inconsistent relationships between financial burden and parental psychological distress highlight the need to identify psychosocial factors that may moderate this relationship. In this study, we aimed to determine if family ritual meaning moderates the relationship between financial burden and anxiety and depression symptoms among mothers of children with cancer. Portuguese mothers of children with cancer on-treatment and off-treatment (N = 244) completed measures of financial burden, anxiety and depression symptoms, and family ritual meaning. Moderating effects were tested using hierarchical multiple regression analyses. Family ritual meaning buffered the effect of financial burden on anxiety, but not on depression symptoms. The relationship between financial burden and anxiety symptoms was not significant when mothers endorsed higher levels of family ritual meaning. Although preliminary, the current findings suggest that high levels of perceived family ritual meaning may constitute a protective factor against the effect of financial burden on mothers' anxiety symptoms. Promoting family ritual meaning might be an effective approach to reducing anxiety symptoms of mothers of children with cancer in the context of financial burden.

There are an estimated 35 million people living with human immunodeficiency virus (HIV) globally, 19 million of whom are unaware of their HIV status and, in the absence of antiretroviral therapy (ART), will have a shortened life expectancy. Although ART remains the "gold standard" for treatment of HIV infection, the requirement for lifelong treatment poses multiple challenges for the patient. These include stigma, an untenable pill burden, side effects, and the threat of viral resistance in the case of non-compliance. This review evaluates the challenges of accessing, delivering, and sustaining ART for people living with HIV and will discuss the case for pursuing a goal of HIV cure, the potential benefits of such a cure for the individual patient, and the current potential candidates for such a cure.

Brain tumors are the most common solid tumor in childhood, yet outcomes vary dramatically. High-grade gliomas have dismal outcomes with poor survival. By contrast, low-grade gliomas, have high survival rates, but children suffer from morbidity of tumor burden and therapy-associated side effects. In this article, we discuss how current trial designs often miss the opportunity to include end points beyond tumor response and thus fail to offer complete assessments of therapeutic approaches. Quality of life, neurocognitive function and neurofunctional deficits need to be considered when assessing overall success of a therapy. Herein, we identify specific end points that should be included in the interpretation of clinical trial results and accordingly, offer a more comprehensive approach to treatment decision-making.

Pediatric uveitis is a topic of special interest not only because of the unique diagnostic and therapeutic challenges but also because of the lifetime burden of vision loss if the problem is not adequately treated, as well as the economic and psychological toll on the family. Often, uveitis in children is discovered as part of a routine eye exam; this silent, insidious inflammation can be difficult to treat and can lead to further complications if not handled skillfully. Corticosteroids have long been the mainstay of therapy; however, the significant associated side effects mandate a corticosteroid-sparing therapeutic regimen in pursuit of remission. In this review, we cover the therapeutic options for pediatric uveitis, specifically focusing on the most common non-infectious varieties, juvenile idiopathic arthritis-associated uveitis and pars planitis.

Alzheimer's disease (AD), the most common neurodegenerative disorder associated with dementia, not only severely decreases the quality of life for its victims, but also brings a heavy economic burden to the family and society. Unfortunately, few chemical drugs designed for clinical applications have reached the expected preventive or therapeutic effect so far, and combined with their significant side-effects, there is therefore an urgent need for new strategies to be developed for AD treatment. Traditional Chinese Medicine has accumulated many experiences in the treatment of dementia during thousands of years of practice; modern pharmacological studies have confirmed the therapeutic effects of many active components derived from Chinese herbal medicines (CHM). Ginsenoside Rg1, extracted from Radix Ginseng, exerts a [Formula: see text]-secretase inhibitor effect so as to decrease A[Formula: see text] aggregation. It can also inhibit the apoptosis of neuron cells. Tanshinone IIA, extracted from Radix Salviae miltiorrhizae, and baicalin, extracted from Radix Scutellariae[Formula: see text] can inhibit the oxidative stress injury in neuronal cells. Icariin, extracted from Epimedium brevicornum, can decrease A[Formula: see text] levels and the hyperphosphorylation of tau protein, and can also inhibit oxidative stress and apoptosis. Huperzine A, extracted from Huperzia serrata, exerts a cholinesterase inhibitor effect. Evodiamine, extracted from Fructus Evodiae, and curcumin, extracted from Rhizoma Curcumae Longae, exert anti-inflammatory actions. Curcumin can act on A[Formula: see text] and tau too. Due to the advantages of multi-target effects and fewer side effects, Chinese medicine is more appropriate for long-term use. In this present review, the pharmacological effects of commonly used active components derived from Chinese herbal medicines in the treatment of AD are discussed.

Strategies for reducing the treatment-related physical burden of childhood acute myeloid leukaemia - a review.

Over the last four decades the survival of paediatric patients with acute myeloid leukaemia has gradually increased to 70% in high-income countries. The therapy is very intensive and associated with many acute and long-term side effects. The early death rate has been reduced to 1-4%. The acute toxicity is a limiting factor for improving survival in low-income countries. Transplant is associated with more endocrinological late effects while cardiotoxicity is more common after relapse. Reducing the physical costs of therapy without jeopardizing survival may be accomplished by optimal supportive care, less cardiotoxic anthracyclines, less consolidation courses and strict indications for stem cell transplantation. Analysing scenarios with different frequency of transplantation in first complete remission show similar overall survival rates, indicating that almost all patients can be spared the procedure in first remission. Reducing relapse risk is an effective way of reducing toxicity and more targeted therapy and improved risk group stratifications are needed. © 2016 John Wiley & Sons Ltd.

Optimizing Industrial Consumer Demand Response Through Disaggregation, Hour-Ahead Pricing, and Momentary Autonomous Control

NASA Astrophysics Data System (ADS)

Abdulaal, Ahmed

The work in this study addresses the current limitations of the price-driven demand response (DR) approach. Mainly, the dependability on consumers to respond in an energy aware conduct, the response timeliness, the difficulty of applying DR in a busy industrial environment, and the problem of load synchronization are of utmost concern. In order to conduct a simulation study, realistic price simulation model and consumers' building load models are created using real data. DR action is optimized using an autonomous control method, which eliminates the dependency on frequent consumer engagement. Since load scheduling and long-term planning approaches are infeasible in the industrial environment, the proposed method utilizes instantaneous DR in response to hour-ahead price signals (RTP-HA). Preliminary simulation results concluded savings at the consumer-side at the cost of increased supplier-side burden due to the aggregate effect of the universal DR policies. Therefore, a consumer disaggregation strategy is briefly discussed. Finally, a refined discrete-continuous control system is presented, which utilizes multi-objective Pareto optimization, evolutionary programming, utility functions, and bidirectional loads. Demonstrated through a virtual testbed fit with real data, the new system achieves momentary optimized DR in real-time while maximizing the consumer's wellbeing.

The common cold is one of the most common illnesses in humans and constitutes an economic burden both in terms of productivity and expenditure for treatment. There is no proven cure for the common cold and symptomatic relief is the mainstay of treatment. The use of intranasal ipratropium bromide (IB) has been addressed in several studies and might prove an effective treatment for the common cold. To determine the effect of IB versus placebo or no treatment on severity of rhinorrhoea and nasal congestion in children and adults with the common cold. Subjective overall improvement was another primary outcome and side effects (for example, dry mucous membranes, epistaxis and systemic anticholinergic effects) were reported as a secondary outcome. In this updated review we searched CENTRAL 2013, Issue 3, MEDLINE (1950 to March week 4, 2013), MEDLINE in-process and other non-indexed citations (8 April 2013), EMBASE (1974 to April 2013), AMED (1985 to April 2013), Biosis (1974 to February 2011) and LILACS (1985 to April 2013). Randomised controlled trials (RCTs) comparing IB to placebo or no treatment in children and adults with the common cold. Two review authors independently extracted data and assessed trial quality. We used a standardised form to extract relevant data and we contacted trial authors for additional information. Seven trials with a total of 2144 participants were included. Four studies (1959 participants) addressed subjective change in severity of rhinorrhoea. All studies were consistent in reporting statistically significant changes in favour of IB. Nasal congestion was reported in four studies and was found to have no significant change between the two groups. Two studies found a positive response in the IB group for the global assessment of overall improvement. Side effects were more frequent in the IB group, odds ratio (OR) 2.09 (95% confidence interval (CI) 1.40 to 3.11). Commonly encountered side effects included nasal dryness, blood tinged mucus and epistaxis. The overall risk of bias in the included studies was moderate. For people with the common cold, the existing evidence, which has some limitations, suggests that IB is likely to be effective in ameliorating rhinorrhoea. IB had no effect on nasal congestion and its use was associated with more side effects compared to placebo or no treatment although these appeared to be well tolerated and self limiting. There is a need for larger, high-quality trials to determine the effectiveness of IB in relieving common cold symptoms.

To date, this balance has been achieved by varying the cationic charge or side chain hydrophobicity in a variety of cationic-amphiphilic polymers. Optimal hydrophobicity of cationic-amphiphilic polymers has been considered as the governing factor for potent antibacterial activity yet minimal mammalian cell toxicity. However, the concomitant role of hydrogen bonding and hydrophobicity with constant cationic charge in the interactions of antibacterial polymers with bacterial membranes is not understood. Also, degradable polymers that result in nontoxic degradation byproducts offer promise as safe antibacterial agents. Here we show that amide- and ester (degradable)-bearing cationic-amphiphilic polymers with tunable side chain hydrophobicity can modulate antibacterial activity and cytotoxicity. Our results suggest that an amide polymer can be a potent antibacterial agent with lower hydrophobicity whereas the corresponding ester polymer needs a relatively higher hydrophobicity to be as effective as its amide counterpart. Our studies reveal that at higher hydrophobicities both amide and ester polymers have similar profiles of membrane-active antibacterial activity and mammalian cell toxicity. On the contrary, at lower hydrophobicities, amide and ester polymers are less cytotoxic, but the former have potent antibacterial and membrane activity compared to the latter. Incorporation of amide and ester moieties made these polymers side chain degradable, with amide polymers being more stable than the ester polymers. Further, the polymers are less toxic, and their degradation byproducts are nontoxic to mice. More importantly, the optimized amide polymer reduces the bacterial burden of burn wound infections in mice models. Our design introduces a new strategy of interplay between the hydrophobic and hydrogen bonding interactions keeping constant cationic charge density for developing potent membrane-active antibacterial polymers with minimal toxicity to mammalian cells.

Clostridium difficile infection is a major economic and clinical burden, due to its high frequency of recurrence. Currently recommended treatments are not efficient for prevention and may contribute to the risk of recurrent infection. In recent years, research has focused on strategies to lessen this risk. Bezlotoxumab is a monoclonal antibody that prevents recurrences of C. difficile infection through the antagonism of toxin B. Areas covered: In this review, the authors discuss the burden of C. difficile infection and its recurrences, the mechanisms underlying the recurrences, and current C. difficile treatments. They subsequently analyze the strategic therapeutic rationale for bezlotoxumab use, as well as the supporting clinical evidence. Expert opinion: Bezlotoxumab is an attractive solution for reducing the unacceptable level of recurrence that occurs with the currently recommended C. difficile treatments and other alternative therapies under consideration. Even though bezlotoxumab has not been tested in large-scale trials exclusively in cases of already established recurrent C.difficile infection (rCDI), it has an advantage over current treatments in that it does not interfere with the patient's gut flora while directly neutralizing the key virulence factor. Although cost remains an important factor against its widespread use, simpler administration, fewer side-effects, and better social acceptability justify its consideration for treating rCDI.

An emerging epidemic: cancer and heart failure.

Heart disease and cancer are the two leading causes of mortality globally. Cardiovascular complications of cancer therapy significantly contribute to the global burden of cardiovascular disease. Heart failure (HF) in particular is a relatively common and life-threatening complication. The increased risk is driven by the shared risk factors for cancer and HF, the direct impact of cancer therapy on the heart, an existing care gap in the cardiac care of patients with cancer and the increasing population of adult cancer survivors. The clear relationship between cancer treatment initiation and the potential for myocardial injury makes this population attractive for prevention strategies, targeted cardiovascular monitoring and treatment. However, there is currently no consensus on the optimal strategy for managing this at-risk population. Uniform treatment using cardioprotective medications may reduce the incidence of HF, but would impose frequently unnecessary and burdensome side effects. Ideally we could use validated risk-prediction models to target HF-preventive strategies, but currently no such models exist. In the present review, we focus on evidence and rationales for contemporary clinical decision-making in this novel field and discuss issues, including the burden of HF in patients with cancer, the reasons for the elevated risk and potential prevention strategies. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

Radiofrequency ablation (RFA) is the foremost treatment option for advanced hepatocellular carcinoma (HCC), however, rapid and aggressive recurrence of HCC often occurs after RFA due to epithelial-mesenchymal transition process. Although combination of RFA with sorafenib, a molecular targeted agent, could attenuate the recurrence of HCC, application of this molecular targeted agent poses a heavy medical burden and oral administration of sorafenib also brings severe side effects. In this study, we prepared an apatinib microcrystal formulation (Apa-MS) that sustainably releases apatinib, a novel molecular targeted agent, for advanced HCC treatment. We injected apatinib solution or Apa-MS into subcutaneous HCC tumors. It was found that Apa-MS exhibited slow apatinib release in vivo and in turn inhibited the epithelial-mesenchymal transition of HCC cells for extended time. Moreover, in rodent HCC model, Apa-MS enhanced the antitumor effect of RFA treatment. Based on these results, we conclude that Apa-MS, a slow releasing system of apatinib, allows apatinib to remain effective in tumor tissues for a long time and could enhance the antitumor effect of RFA on HCC.

Irritable Bowel Syndrome (IBS) is a chronic digestive disorder, which is characterized by abdominal pain, bloating, diarrhea and constipation periods. The etiology is unknown. Based on the different mechanisms in the etiology, treatment focuses on controlling symptoms. Due to the longtime of syndrome, inadequacy of current treatments, financial burden for patients and pharmacologic effects, several patients have turned to the use of complementary and alternative medicine (CAM). Complementary and alternative treatments for IBS include hypnosis, acupuncture, cognitive behavior therapy, yoga, and herbal medicine. Herbal medicines can have therapeutic effects and adverse events in IBS. The aim of this study was to evaluate the efficacy of herbal medicines in the control of IBS, and their possible mechanisms of action were reviewed. Herbal medicines are an important part of the health care system in many developing countries It is important for physicians to understand some of the more common forms of CAM, because some herbs have side effects and some have interactions with conventional drugs. However herbal medicines may have therapeutic effects in IBS, and further clinical research is needed to assess its effectiveness and safety.

Diagnosing and treating depression in epilepsy.

At least one third of patients with active epilepsy suffer from significant impairment of their emotional well-being. A targeted examination for possible depression (irrespective of any social, financial or personal burdens) can identify patients who may benefit from medical attention and therapeutic support. Reliable screening instruments such as the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) are suitable for the timely identification of patients needing help. Neurologists should be capable of managing mild to moderate comorbid depression but referral to mental health specialists is mandatory in severe and difficult-to-treat depression, or if the patient is acutely suicidal. In terms of the therapeutic approach, it is essential first to optimize seizure control and minimize unwanted antiepileptic drug-related side effects. Psychotherapy for depression in epilepsy (including online self-treatment programs) is underutilized although it has proven effective in ten well-controlled trials. In contrast, the effectiveness of antidepressant drugs for depression in epilepsy is unknown. However, if modern antidepressants are used (e.g. SSRI, SNRI, NaSSA), concerns about an aggravation of seizures and or problematic interactions with antiepileptic drugs seem unwarranted. Epilepsy-related stress ("burden of epilepsy") explains depression in many patients but acute and temporary seizure-related states of depression or suicidality have also been reported. Limbic encephalitits may cause isolated mood alteration without any recognizable psychoetiological background indicating a possible role of neuroinflammation. This review will argue that, overall, a bio-psycho-social model best captures the currently available evidence relating to the etiology and treatment of depression as a comorbidity of epilepsy.

Objective To determine whether ultraviolet B phototherapy at home is equally safe and equally effective as ultraviolet B phototherapy in an outpatient setting for patients with psoriasis. Design Pragmatic multicentre single blind randomised clinical trial (PLUTO study). Setting Dermatology departments of 14 hospitals in the Netherlands. Participants 196 patients with psoriasis who were clinically eligible for narrowband (TL-01) ultraviolet B phototherapy. The first 105 consecutive patients were also followed for one year after therapy. Intervention Ultraviolet B phototherapy at home using a TL-01 home phototherapy unit compared with standard narrowband ultraviolet B phototherapy in an outpatient setting. Both therapies were done in a setting reflecting routine daily practice in the Netherlands. Main outcome measures The main outcome measure was effectiveness as measured by the proportion of patients with a 50% or more reduction of the baseline psoriasis area and severity index (PASI) or self administered psoriasis area and severity index (SAPASI), called the PASI 50 and SAPASI 50 (relevant treatment effect). Another outcome of effectiveness was the percentage reduction in median scores on the PASI as well as SAPASI. Also the proportions of patients reaching the PASI 75 and SAPASI 75 (successful treatment effect), and the PASI 90 and SAPASI 90 (almost complete clearance) were calculated. Other secondary outcomes were quality of life (SF-36, psoriasis disability index), burden of treatment (questionnaire), patients’ preferences and satisfaction (questionnaire), and dosimetry and short term side effects (diary). Results 82% of the patients treated at home compared with 79% of the patients treated in an outpatient setting reached the SAPASI 50 (difference 2.8%, 95% confidence interval −8.6% to 14.2%), and 70% compared with 73% reached the PASI 50 (−2.3%, −15.7% to 11.1%). For patients treated at home the median SAPASI score decreased 82% (from 6.7 to 1.2) and the median PASI score decreased 74% (from 8.4 to 2.2), compared with 79% (from 7.0 to 1.4) and 70% (from 7.0 to 2.1) for patients treated in an outpatient setting. Treatment effect as defined by the mean decline in PASI and SAPASI scores was significant (P<0.001) and similar across groups (P>0.3). Total cumulative doses of ultraviolet B light were similar (51.5 v 46.1 J/cm2, difference 5.4, 95% confidence interval −5.2 to 16.0), and the occurrence of short term side effects did not differ. The burden of undergoing ultraviolet B phototherapy was significantly lower for patients treated at home (differences 1.23 to 3.01, all P≤0.001). Quality of life increased equally regardless of treatment, but patients treated at home more often rated their experience with the therapy as “excellent” (42%, 38/90) compared with patients treated in the outpatient department (23%, 20/88; P=0.001). Conclusion Ultraviolet B phototherapy administered at home is equally safe and equally effective, both clinically and for quality of life, as ultraviolet B phototherapy administered in an outpatient setting. Furthermore, ultraviolet B phototherapy at home resulted in a lower burden of treatment and led to greater patients’ satisfaction.

To investigate women's values and preferences regarding antiretroviral therapy (ART) during pregnancy to inform a BMJ Rapid Recommendation. Primary studies reporting patient-reported outcomes relevant to decision-making regarding ART in any clinical and geographical setting. Women living with HIV who are pregnant, postpartum or considering pregnancy. Quantitative measurements and qualitative descriptions of values and preferences in relation to ART during pregnancy. We also included studies on women's reported barriers and facilitators to adherence. We excluded studies correlating objective measures (eg, CD4 count) with adherence, or reporting only outcomes which are not expected to differ between ART alternatives (eg, access to services, knowledge about ART). We included 15 qualitative studies reporting values and preferences about ART in the peripartum period; no study directly studied choice of ART therapy during pregnancy. Six themes emerged: a desire to reduce vertical transmission (nine studies), desire for child to be healthy (five studies), concern about side effects to the child (eight studies), desire for oneself to be healthy (five studies), distress about side effect to oneself (10 studies) and pill burden (two studies). None of the studies weighed the relative importance of these outcomes directly, but pill burden/medication complexity appears to be a lower priority for most women compared with other factors. Overall, the body of evidence was at low risk of bias, with minor limitations. Women who are or may become pregnant and who are considering ART appear to place a high value on both their own and their children's health. Evidence on the relative importance between these values when choosing between ART regimens is uncertain. There is variability in individual values and preferences among women. This highlights the importance of an individualised women-centred approach, such as shared decision-making when choosing between ART alternatives.

The BURDEN IBS-C study was conducted to better understand the experiences, attitudes, and unmet needs of sufferers of irritable bowel syndrome with constipation (IBS-C) in comparison to the perceptions and challenges of healthcare providers (HCPs) who treat IBS-C patients. This was an author-developed, online questionnaire using KnowledgePanel ® to survey individuals with IBS-C (N = 1311). HCPs participated in a complementary online questionnaire and were recruited separately (N = 331). The study was fielded from June 29, 2016, to January 30, 2017. Most patients had used (86%) and/or were using (76%) over-the-counter treatments for their IBS-C, with 12% currently on prescription therapy. At the time this study was conducted, 66% and 63% were not satisfied/completely satisfied with over-the-counter or prescription treatment, respectively, citing inadequate efficacy (55%) and side effects (39%), most commonly diarrhea, as common reasons for dissatisfaction. IBS-C respondents most commonly reported feeling frustrated (43%) and stressed (28%) regarding IBS-C, though 39% were accepting of IBS-C as part of daily life. HCPs were aligned with patients in thinking that patients were frustrated (76%) and stressed (65%) but HCPs were less likely to recognize that patients had become accepting of their IBS-C (13%). Most HCPs (79%) were not satisfied/completely satisfied with the prescription treatments available at the time this study was conducted. Inadequate response rates to current therapies (55%) and treatment adherence/compliance issues (58%) were the most frequent challenges encountered by HCPs. IBS-C respondents reported that their symptoms impacted productivity and personal activity, on average, 4 and 3 days/month, respectively. These results suggest that current management pathways may not be adequately addressing the symptoms and needs of individuals with IBS-C, most notably side effects and lack of efficacy. Patients and HCPs expressed dissatisfaction with over-the-counter and prescription treatments available at the time this study was conducted. Additional treatment options and improved dialogue would be beneficial to HCPs and patients. Synergy Pharmaceuticals Inc.

There is a need to identify rational criteria and set priorities for vaccines. In Thailand, many licensed vaccines are being considering for introduction into the Expanded Program on Immunization; thus, the government has to make decisions about which vaccines should be adopted. This study aimed to set priorities for new vaccines and to facilitate decision analysis. We used a best-worst scaling study for rank-ordering of vaccines. The candidate vaccines were determined by a set of criteria, including burden of disease, target age group, budget impact, side effect, effectiveness, severity of disease, and cost of vaccine. The criteria were identified from a literature review and by in-depth, open-ended interviews with experts. The priority-setting model was conducted among three groups of stakeholders, including policy makers, healthcare professionals and healthcare administrators. The vaccine data were mapped and then calculated for the probability of selection. From the candidate vaccines, the probability of hepatitis B vaccine being selected by all respondents (96.67 %) was ranked first. This was followed, respectively, by pneumococcal conjugate vaccine-13 (95.09 %) and Haemophilus influenzae type b vaccine (90.87 %). The three groups of stakeholders (policy makers, healthcare professionals and healthcare administrators) showed the same ranking trends. Most severe disease, high fever rate and high disease burden showed the highest coefficients for criterion levels being selected by all respondents. This result can be implied that a vaccine which can prevent most severe disease with high disease burden and has low safety has a greater chance of being selected by respondents in this study. The priority setting of vaccines through a multiple-criteria approach could contribute to transparency and accountability in the decision-making process. This is a step forward in the development of an evidence-based approach that meets the need of developing country. The methodology is generalizable but its application to another country would require the criteria as relevant to that country.

To assess disease burden of chemotherapy-induced peripheral neuropathy (CIPN), which is a common dose-limiting side effect of neurotoxic chemotherapy. Late effects of CIPN may increase with improved cancer survival. Olmsted County, Minnesota residents receiving neurotoxic chemotherapy were identified and CIPN was ascertained via text searches of polyneuropathy symptoms in the medical record. Clinical records were queried to collect data on baseline characteristics, risk factors, signs and symptoms of CIPN, medications, impairments and International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes for all subjects. A total of 509 individuals with incident exposure to an inclusive list of neurotoxic chemotherapy agents between 2006 and 2008 were identified. 268 (52.7%) of these individuals were determined to have CIPN. The median time from incident exposure to first documented symptoms was 71 days. Patients with CIPN received a neuropathy ICD-9 diagnosis in only 37 instances (13.8%). Pain symptoms and use of pain medications were observed more often in patients with CIPN. Five-year survival was greater in those with CIPN (55.2%) versus those without (36.1%). Those with CIPN surviving greater than 5 years (n=145) continued to have substantial impairments and were more likely to be prescribed opioids than those without CIPN (OR 2.0, 1.06-3.69). Results from our population-based study are consistent with previous reports of high incidence of CIPN in the first 2 years following incident exposure to neurotoxic chemotherapeutic agents, and its association with significant pain symptomatology and accompanied long-term opioid use. Increased survival following exposure to neurotoxic chemotherapy and its long-term disease burden necessitates further study among survivors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

In the Russian Federation (Russia), an elevated burden of premature mortality attributable to non-communicable diseases (NCDs) has been observed since the country's economic transition. NCDs are largely related to preventable risk factors such as unhealthy diets. This health policy study's aim was to analyze past and current food production and nutritional trends in Russia and their policy implications for Russia's NCD burden. We examined food security and nutrition in Russia using an analytical framework of food availability, access to food, and consumption. Agricultural production declined during the period of economic transition, and nutritional habits changed from high-fat animal products to starches. However, per-capita energy consumption remained stable due to increased private expenditures on food and use of private land. Paradoxically, the prevalence of obesity still increased because of an excess consumption of unsaturated fat, sugar, and salt on one side, and insufficient intake of fruit and vegetables on the other. Policy and economic reforms in Russia were not accompanied by a food security crisis or macronutrient deprivation of the population. Yet, unhealthy diets in contemporary Russia contribute to the burden of NCDs and related avoidable mortality. Food and nutrition policies in Russia need to specifically address nutritional shortcomings and food-insecure vulnerable populations. Appropriate, evidence-informed food and nutrition policies might help address Russia's burden of NCDs on a population level.

In the context of inpatient and increasingly ambulatory thrombosis prophylaxis, heparins have been recognised as standard therapy for decades. In addition to the therapeutic benefit, therapy with heparins also entails the risk of undesirable side effects, such as bleeding and thrombocytopenia. Heparin-induced thrombocytopenia (HIT II) is deemed a serious side effect. In the following work, HIT II is subjected to a medico-economic consideration (treatment, pharmaceuticals, subsequent costs due to possible complications) and, with regard to a possible HIT II prophylaxis, aspects of increasingly respected patient safety are also considered. In the context of a literature search the active ingredients argatroban and danaparoid, which are approved for HIT II treatment, were evaluated. HIT II - especially in combination with thromboembolic complications - represents a medical-economic burden for the hospital. Although this is only an orientation guide, it shows that HIT II syndrome is not adequately cost-covered by the G‑DRG system. An early thrombosis prophylaxis with argatroban/danaparoid for HIT II risk patients should therefore be taken into account for medical-related as well as patient safety-relevant aspects. According to experience, the pharmaceutical supply for these medically needed products (anticoagulants) should be ensured for reasons of patient safety. The risk of an immunological response to heparin therapy is known. Within the context of increased patient safety, thrombosis prophylaxis should be issued with a risk-adjusted prophylaxis.

Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis.

Oray, Merih; Tuğal-Tutkun, İlknur

Pediatric uveitis may be a serious health problem because of the lifetime burden of vision loss due to severe complications if the problem is not adequately treated. Juvenile idiopathic arthritis (JIA)-associated uveitis is characterized by insidious onset and potentially blinding chronic anterior uveitis. Periodic ophthalmologic screening is of utmost importance for early diagnosis of uveitis. Early diagnosis and proper immunomodulatory treatment are essential for good visual prognosis. The goal of treatment is to achieve enduring drug-free remission. The choice of therapeutic regimen needs to be tailored to each individual case. One must keep in mind that patients under immunomodulatory treatment should be monitored closely due to possible side effects. Local and systemic corticosteroids have long been the mainstay of therapy; however, long-term corticosteroid therapy should be avoided due to serious side effects. Steroid-sparing agents in the treatment of JIA-associated uveitis include antimetabolites and biologic agents in refractory cases. Among the various immunomodulatory agents, methotrexate is generally the first choice, as it has a well-established safety and efficacy profile in pediatric cases and does not appear to increase the risk of cancer. Other classic immunomodulators that may also be used in combination with methotrexate include azathioprine, mycophenolate mofetil, and cyclosporin A. Biologic agents, primarily tumor necrosis factor alpha inhibitors including infliximab or adalimumab, should be considered in cases of treatment failure with classic immunomodulatory agents.

Health-related quality of life (HRQoL) from diagnosis until end of treatment for children with acute lymphoblastic leukaemia was investigated, examining effects of age, gender, risk-stratified treatment regimen, and therapy intensity (one vs. two 'delayed intensifications' [DIs]). In a multi-centre prospective study, parents reported their child's generic and disease-specific HRQoL and their own care-giving burden at five time points. From 1,428 eligible patients, 874 parents completed questionnaires at least once during treatment. At each time point, generic HRQoL was significantly lower than equivalent norm scores for healthy children. HRQoL decreased significantly at the start of treatment, before recovering gradually (but remained below pre-treatment levels). Parents reported that older children worried more about side effects and their appearance, but showed less procedural anxiety than younger children. Concern for appearance was greater among girls than boys. Compared to Regimen B (i.e. additional doxorubicin during induction and additional cyclophosphamide and cytarabine during consolidation chemotherapy), patients receiving Regimen A had fewer problems with pain and nausea. There were no statistically significant differences in HRQoL by number of DI blocks received. HRQoL is compromised at all stages of treatment, and is partly dependent on age. The findings increase understanding of the impact of therapy on children's HRQoL and parental care-giving burden, and will contribute to the design of future trials. © 2017 The Authors.

Hypertriglyceridemia is defined as a level of triglycerides above 150 mg/dL. The complex causes and classification of hypertriglyceridemia lead to difficulties in the diagnosis and management of this condition. We present the case of a 15 years and 6 months old female teenager, admitted in our clinic for the following complaints: severe abdominal pain predominantly in the lateral left quadrant, nausea, vomiting, and the lack of stools for 2 days. The clinical exam showed: impaired general status, painful abdomen at superficial and deep palpation in the left and upper abdominal quadrants, the absence of stools for 2 days. The laboratory parameters revealed leukocytosis with neutrophilia, thrombocytopenia, high level of serum amylase and triglycerides, and increased inflammatory biomarkers. The imagistic investigations showed ascites and paralytic ileus. The management was burdened by the side-effects of hypolipidemic drugs impairing the liver function and leading to rhabdomyolysis, but eventually the patient's outcome was good. Type V hyperlipoproteinemia is a rare condition accounting for approximately 5% of the cases. The risk for acute pancreatitis is well-known to be associated with hypertriglyceridemia, even though in rare cases. The prognosis of hypertriglyceridemia is pediatrics is burdened not only by the long-term risk factors associated to the diseases itself, but also by the negative effects of long-term hypolipidemic treatment.

To explore the effectiveness of a psycho-educational family intervention program for reducing burden in caregivers of patients with schizophrenia in a developing country. Forty-five caregivers participated, 22 in a psycho-educational family intervention group and 23 in a control group. The family program was held once a week for 5 months. In the control group the caregivers received standard intervention, comprising periodical meetings with the staff to monitor the effects of the medication. Burden was measured before and after the intervention: relatives in the psycho-educational group were evaluated at inclusion and at the end of the program; controls were evaluated at inclusion and 5 months later. Burden decreased significantly in the psycho-educational group; mean scores on the Zarit Caregiver Burden Scale fell from 85.06 pre-intervention to 52.44 post-intervention, while scores fell only slightly in the control group, from 87.65 to 87.22. Treatment was especially effective in mothers and caregivers with lower educational levels. This intervention program for reducing caregiver burden in developing Latin American countries was effective. Future investigations should focus on obtaining more precise estimates of the contributions of specific components of these programs to reducing burden.

Collaborative Approaches and Policy Opportunities for Accelerated Progress toward Effective Disease Prevention, Care, and Control: Using the Case of Poverty Diseases to Explore Universal Access to Affordable Health Care.

There is a massive global momentum to progress toward the sustainable development and universal health coverage goals. However, effective policies to health-care coverage can only emerge through high-quality services delivered to empowered care users by means of strong local health systems and a translational standpoint. Health policies aimed at removing user fees for a defined health-care package may fail at reaching desired results if not applied with system thinking. Secondary data analysis of two country-based cost-of-illness studies was performed to gain knowledge in informed decision-making toward enhanced access to care in the context of resource-constraint settings. A scoping review was performed to map relevant experiences and evidence underpinning the defined research area, the economic burden of illness. Original studies reflected on catastrophic costs to patients because of care services use and related policy gaps. Poverty diseases such as tuberculosis (TB) may constitute prime examples to assess the extent of effective high-priority health-care coverage. Our findings suggest that a share of the economic burden of illness can be attributed to implementation failures of health programs and supply-side features, which may highly impair attainment of the global stated goals. We attempted to define and discuss a knowledge development framework for effective policy-making and foster system levers for integrated care. Bottlenecks to effective policy persist and rely on interrelated patterns of health-care coverage. Health system performance and policy responsiveness have to do with collaborative work among all health stakeholders. Public-private mix strategies may play a role in lowering the economic burden of disease and solving some policy gaps. We reviewed possible added value and pitfalls of collaborative approaches to enhance dynamic local knowledge development and realize integration with the various health-care silos. Despite a large political commitment and mobilization efforts from funding, the global development goal of financial protection for health-newly adopted in TB control as no TB-affected household experiencing catastrophic expenditure-may remain aspirational. To enhance effective access to care for all, innovative opportunities in patient-centered and collaborative practices must be taken. Further research is greatly needed to optimize the use of locally relevant knowledge, networks, and technologies.

Why does the burden of disease persist? Relating the burden of anxiety and depression to effectiveness of treatment.

Why does the burden of mental disorders persist in established market economies? There are four possibilities: the burden estimates are wrong; there are no effective treatments; people do not receive treatment; or people do not receive effective treatments. Data from the Australian National Survey of Mental Health and Wellbeing about the two commonest mental disorders, generalized anxiety disorder and depression, have been used in examining these issues. The burden of mental disorders in Australia is third in importance after heart disease and cancer, and anxiety and depressive disorders account for more than half of that burden. The efficacy of treatments for both disorders has been established. However, of those surveyed, 40% with current disorders did not seek treatment in the previous year and only 45% were offered a treatment that could have been beneficial. Treatment was not predictive of disorders that remitted during the year. The burden therefore persists for two reasons: too many people do not seek treatment and, when they do, efficacious treatments are not always used effectively. PMID:10885163

Timely and accurate assessments of disease burden are essential for developing effective national health policies. We used the Global Burden of Disease Study 2015 to examine burden due to mental and substance use disorders in Australia. For each of the 20 mental and substance use disorders included in Global Burden of Disease Study 2015, systematic reviews of epidemiological data were conducted, and data modelled using a Bayesian meta-regression tool to produce prevalence estimates by age, sex, geography and year. Prevalence for each disorder was then combined with a disorder-specific disability weight to give years lived with disability, as a measure of non-fatal burden. Fatal burden was measured as years of life lost due to premature mortality which were calculated by combining the number of deaths due to a disorder with the life expectancy remaining at the time of death. Disability-adjusted life years were calculated by summing years lived with disability and years of life lost to give a measure of total burden. Uncertainty was calculated around all burden estimates. Mental and substance use disorders were the leading cause of non-fatal burden in Australia in 2015, explaining 24.3% of total years lived with disability, and were the second leading cause of total burden, accounting for 14.6% of total disability-adjusted life years. There was no significant change in the age-standardised disability-adjusted life year rates for mental and substance use disorders from 1990 to 2015. Global Burden of Disease Study 2015 found that mental and substance use disorders were leading contributors to disease burden in Australia. Despite several decades of national reform, the burden of mental and substance use disorders remained largely unchanged between 1990 and 2015. To reduce this burden, effective population-level preventions strategies are required in addition to effective interventions of sufficient duration and coverage.

1 Hypothesis Disabled elders' activities of daily living, caregiver burden, caregiver depression, and caregivers' life satisfaction are significantly related to the life satisfaction of elderly people with disability. 2 Hypothesis There are direct and indirect effects between the life satisfaction of elders, disabled elders' activities of daily living, and family caregivers' factors. This study explored the interrelationships of disabled elders' life satisfaction and activities of daily living, caregivers' factors (burden, depression, and life satisfaction) through a structural equation model. In total, 621 dyads of disabled elders and informal family caregivers completed questionnaires during face-to-face interviews in Xinjiang Uyghur Autonomous Region from September 2013 to January 2014. Activity of daily living exerted a direct effect on life satisfaction of disabled elders and 30.4% indirect effect through caregivers' factors. Caregiver burden had a 60.0% direct effect on life satisfaction of disabled elders and a 40.0% indirect effect through the caregiver depression. Caregiver depression showed 76% direct effect on life satisfaction of disabled elders and 24% indirect effect through caregivers' life satisfaction. Direct relationships between activity of daily living and caregiver burden, caregiver burden and caregiver depression, and caregiver depression and caregivers' life satisfaction were observed. Activity of daily living had a 91.3% indirect effect on caregiver depression mediated by caregiver burden; caregiver burden had a 40.0% indirect effect on caregivers' life satisfaction mediated by caregiver depression. Results provide useful information for nurses and policymakers and shed light on the need to consider caregivers' factors in improving care recipients' life satisfaction. © 2017 John Wiley & Sons Australia, Ltd.

Background: Atopic dermatitis is a chronic skin disease with increasing prevalence worldwide and a considerable burden especially among children. To circumvent the problems related to oral azathioprine (AZT) we aimed to evaluate its topical variant and assess its efficacy in patients aged 2–18. Materials and Methods: In a single-blind trial, we randomized the patients into two groups, one treated with topical emollient containing AZT and betamethasone (BM), and the other treated solely with topical emollient of BM. The treatments were administered twice a day for 8 weeks in both groups. The efficacy, recurrence, and the presence of side effects were evaluated using SPSS 20. Results: The amount of reduction in severity scoring for atopic dermatitis (SCORAD) score was significantly greater in the group treated with the topical AZT (P = 0.024). Incidentally, there were no difference between two treatments in difference in proportions of recurrence and adverse effects as well as SCORAD reduction in subgroups of sex and age (all P > 0.05). Conclusions: Our results showed the superiority of topical AZT over BM with a low recurrence and adverse effects. No expectation of severe side effects, like those of oral AZT, is the major advantage of topical AZT. The sample size was an issue in uncovering the value of AZT in the subgroups. Conducting prolonged studies of quality-of-life and comparing the topical AZT potency relative to the common alternatives are recommended areas of future work. PMID:26623403

Thalassemia, a chronic blood disease, necessitates life-long adherence to blood transfusions and chelation therapy to reduce iron overload. We examine stability of health-related quality of life (HRQOL) in thalassemia and adherence to chelation therapy over time, especially after changes in chelator choice. Thalassemia Longitudinal Cohort participants in the USA, UK, and Canada completed the SF-36v2 (ages 14+) and the PF-28 CHQ (parents of children <14 years). Chelation adherence was defined as self-reported percent of doses administered in the last 4 weeks. Two hundred and fifty-eight adults/adolescents (mean 29.7 years) and 133 children (mean 8.5 years) completed a mean of 2.8-years follow-up. Children made few chelator changes, whereas a mean of 2.2 changes was observed among the 37% of adults/adolescents who made chelator changes, mainly due to patient preference or medical necessity. Physical HRQOL improved among those with lower iron burden (better health status) at baseline who made a single change in chelator, but declined among participants with multiple changes and/or high iron burden (worse health status). Mental health improved among participants with lower iron burden, but iron overload was negatively associated with social functioning. Adherence did not significantly change over follow-up except for an increase after a change from deferoxamine (DFO) infusion to oral deferasirox (p = 0.03). Predictors of lower adherence for adults/adolescents at follow-up included side effects, smoking, younger age, problems preparing DFO, increased number of days per week DFO prescribed, and lower physical quality of life . Strategies to balance medical needs with family, work, and personal life may assist in adherence.

Family demands, social support and caregiver burden in Taiwanese family caregivers living with mental illness: the role of family caregiver gender.

The purpose of this study was to assess gender effects on family demands, social support and caregiver burden as well as to examine contributing factors of caregiver burden in caring for family members with mental illness. Providing continued care and support for people with mental illness is demanding and challenging. Findings of earlier caregiving studies on the role of caregiver gender in response to caregiver burden and caregiving-related factors have been inconsistent. Little research has been undertaken to examine gender effect on family demands, social support and caregiver burden in Taiwanese family caregivers of individuals with mental illness. Cross-sectional, descriptive correlation design. Data from 43 families, including at least one male and female family caregiver in each family, were analysed using descriptive statistics, principal component analysis and mixed linear modelling. Demographic data, Perceived Stress Scale, Perceived Social Support and Caregiver Burden Scale-Brief were used to collect data. Female family caregivers perceived less social support and experienced higher degrees of caregiver burden compared with male family caregivers. In contrast, no significant gender effect was associated with family demands. Family caregivers with greater family demands and less social support experienced higher degrees of caregiver burden. The results reinforced those of previously published studies that caregiver burden is highly prevalent among female family caregivers. Caregiver gender appears to be highly valuable for explaining family demands, social support and caregiver burden. Health care professionals should continue to collaborate with family caregivers to assess potential gender effects on available support and design gender-specific interventions to alleviate caregiver burden. © 2010 Blackwell Publishing Ltd.

Research demonstrates that patients with fibromyalgia who have higher positive and lower negative affect have lower symptom burden. Affect has been shown to be associated with resilience. This study examined the relationship between affect, resilience, and fibromyalgia symptom burden in a clinical sample of patients with fibromyalgia. We hypothesized that (a) positive and negative affect would be associated with fibromyalgia symptom burden; (b) resilience would be associated with positive and negative affect; (c) resilience would be associated with fibromyalgia symptom burden; and (d) the connection between resilience and fibromyalgia symptom burden would be mediated by both positive and negative affect. A sample of 858 patients with fibromyalgia completed questionnaires. Mediation modeling revealed statistically significant direct effects of resilience on fibromyalgia symptom burden (β =−.10, P < .001) and statistically significant indirect effects of resilience on fibromyalgia symptom burden through affect (β =−.36, P < .001), suggesting that both resilience and affect influence fibromyalgia symptom burden. Our results suggest that improving affect through resiliency training could be studied as a modality for improving fibromyalgia symptom burden. PMID:24376184

To determine the cost-effectiveness of averting the burden of disease. We used secondary population data and metaanalyses of various government-funded services and interventions to investigate the costs and benefits of various levels of treatment for rheumatoid arthritis (RA) and osteoarthritis (OA) in adults using a burden of disease framework. Population burden was calculated for both diseases in the absence of any treatment as years lived with disability (YLD), ignoring the years of life lost. We then estimated the proportion of burden averted with current interventions, the proportion that could be averted with optimally implemented current evidence-based guidelines, and the direct treatment cost-effectiveness ratio in dollars per YLD averted for both treatment levels. The majority of people with arthritis sought medical treatment. Current treatment for RA averted 26% of the burden, with a cost-effectiveness ratio of dollar 19,000 per YLD averted. Optimal, evidence-based treatment would avert 48% of the burden, with a cost-effectiveness ratio of dollar 12,000 per YLD averted. Current treatment of OA in Australia averted 27% of the burden, with a cost-effectiveness ratio of dollar 25,000 per YLD averted. Optimal, evidence-based treatment would avert 39% of the burden, with an unchanged cost-effectiveness ratio of dollar 25,000 per YLD averted. While the precise dollar costs in each country will differ, the relativities at this level of coverage should remain the same. There is no evidence that closing the gap between evidence and practice would result in a drop in efficiency.

The safety of statins in clinical practice.

PubMed

Armitage, Jane

2007-11-24

Statins are effective cholesterol-lowering drugs that reduce the risk of cardiovascular disease events (heart attacks, strokes, and the need for arterial revascularisation). Adverse effects from some statins on muscle, such as myopathy and rhabdomyolysis, are rare at standard doses, and on the liver, in increasing levels of transaminases, are unusual. Myopathy--muscle pain or weakness with blood creatine kinase levels more than ten times the upper limit of the normal range--typically occurs in fewer than one in 10,000 patients on standard statin doses. However, this risk varies between statins, and increases with use of higher doses and interacting drugs. Rhabdomyolysis is a rarer and more severe form of myopathy, with myoglobin release into the circulation and risk of renal failure. Stopping statin use reverses these side-effects, usually leading to a full recovery. Asymptomatic increases in concentrations of liver transaminases are recorded with all statins, but are not clearly associated with an increased risk of liver disease. For most people, statins are safe and well-tolerated, and their widespread use has the potential to have a major effect on the global burden of cardiovascular disease.

Topiramate in schizophrenia: a review of effects on psychopathology and metabolic parameters.

Less than half of patients with schizophrenia obtain full response to antipsychotic drugs and, while clozapine represents the treatment of choice for refractory psychosis, a significant number of individuals remain only partially responsive. Despite a need for augmentation in this subpopulation, to date clear choices have not been forthcoming. Because clozapine, along with the majority of second-generation agents (SGAs), are linked to metabolic disturbances, augmentation strategies that do not further exacerbate these side effects are needed. Topiramate, unlike other anticonvulsants used for augmentation purposes, has been associated with weight loss. This article reviews the safety and efficacy of topiramate in treatment-refractory schizophrenia, including effects on metabolic disturbances, which burden this population. While current evidence specifically examining improvements in psychopathology demonstrates small to moderate benefits with topiramate augmentation, a growing body of evidence suggests that topiramate may have beneficial effects on antipsychotic-induced weight gain. We conclude that topiramate's metabolic profile, taken together with a current lack of evidence supporting a particular augmentation strategy, argues for further well-controlled studies examining its potential as an augmentation strategy in schizophrenia.

During chemotherapy for childhood acute lymphoblastic leukemia, all organs can be affected by severe acute side effects, the most common being opportunistic infections, mucositis, central or peripheral neuropathy (or both), bone toxicities (including osteonecrosis), thromboembolism, sinusoidal obstruction syndrome, endocrinopathies (especially steroid-induced adrenal insufficiency and hyperglycemia), high-dose methotrexate-induced nephrotoxicity, asparaginase-associated hypersensitivity, pancreatitis, and hyperlipidemia. Few of the non-infectious acute toxicities are associated with clinically useful risk factors, and across study groups there has been wide diversity in toxicity definitions, capture strategies, and reporting, thus hampering meaningful comparisons of toxicity incidences for different leukemia protocols. Since treatment of acute lymphoblastic leukemia now yields 5-year overall survival rates above 90%, there is a need for strategies for assessing the burden of toxicities in the overall evaluation of anti-leukemic therapy programs.

Esophageal squamous cell carcinoma continues to heavily burden clinicians worldwide. Researchers have discovered the genomic landscape of esophageal squamous cell carcinoma, which holds promise for an era of personalized oncology care. One of the most pressing problems facing this issue is to improve the understanding of the newly available genomic data, and identify the driver-gene mutations, pathways, and networks. The emergence of a legion of novel targeted agents has generated much hope and hype regarding more potent treatment regimens, but the accuracy of drug selection is still arguable. Other problems, such as cancer heterogeneity, drug resistance, exceptional responders, and side effects, have to be surmounted. Evolving topics in personalized oncology, such as interpretation of genomics data, issues in targeted therapy, research approaches for targeted therapy, and future perspectives, will be discussed in this editorial.

Men's experience of recovery from treatment for prostate cancer has been extensively researched with reports highlighting the physical side effects of treatments such as erectile dysfunction and incontinence. The psychological, emotional and spiritual burden of prostate cancer on men and their partners has received far less attention. In this study, a secondary thematic analysis of data from a series of separate but related qualitative studies with prostate cancer survivors and their partners was conducted to further explore themes of love, hope and faith within this population. This study identified unresolved needs related to the emotive concepts of love, hope and faith. The findings from this study can be employed to refine psychosocial assessments of men with prostate cancer, and provide a more comprehensive understanding of prostate cancer survivors supportive care needs.

2003-01-01

We have investigated the importance of intercontinental transport using source-receptor relationship. A global radon-like and seven regional tracers were used in three-dimensional model simulations to quantify their contributions to column burdens and vertical profiles at world-wide receptors. Sensitivity of these contributions to meteorological input was examined using different years of meteorology in two atmospheric simulations. Results show that Asian emission influences tracer distributions in its eastern downwind regions extending as far as Europe with major contributions in mid- and upper troposphere. On the western and eastern sides of the US, Asian contribution to annual average column burdens are 37% and 5% respectively with strong monthly variations. At an altitude of 10 km, these contributions are 75% and 25% respectively. North American emissions contribute more than 15% to annual average column burden and about 50% at 8 km altitude over the European region. Contributions from tropical African emissions are wide-spread in both the hemispheres. Differences in meteorological input cause non-uniform redistribution of tracer mass throughout the troposphere at all receptors. We also show that in model-model and model-data comparison, correlation analysis of tracer's spatial gradients provides an added measure of model's performance.

We examined the effects of a manualized care management protocol specifically designed for care managers working with caregivers, the Tailored Caregiver Assessment and Referral® (TCARE®) protocol, on caregiver identity discrepancy, burden, and depressive symptoms. Preliminary data from a longitudinal, randomized, controlled intervention study with 266 family caregivers served by 52 care managers in 4 states were analyzed using repeated measures random effects regression procedures. Caregivers in the intervention and control groups were repeatedly assessed for up to 9 months on caregiver identity discrepancy, 3 areas of caregiving burden-objective, relationship, and stress burdens; depression; and intention for nursing home placement. We found significant group by time interaction effects for caregiver identity discrepancy, relationship burden, stress burden, depression, and intention for nursing home placement. Caregivers in the intervention group experienced significant improvement on these measures, whereas caregivers in the control group worsened on these measures over time. The preliminary findings provide strong support for effectiveness of the TCARE® protocol on improving caregiver well-being and mental health outcomes.

Acute skin toxicity is one of the most common side effects of breast cancer radiotherapy. To date, no one has estimated the nonmedical out-of-pocket expenses associated with this side effect. The primary aim of the present descriptive, exploratory study was to assess the feasibility of a newly developed skin toxicity costs questionnaire. The secondary aims were to: (1) estimate nonmedical out-of-pocket costs, (2) examine the nature of the costs, (3) explore potential background predictors of costs, and (4) explore the relationship between patient-reported dermatologic quality of life and expenditures. A total of 50 patients (mean age = 54.88, Stage 0-III) undergoing external beam radiotherapy completed a demographics/medical history questionnaire as well as a seven-item Skin Toxicity Costs (STC) questionnaire and the Skindex-16 in week 5 of treatment. Mean skin toxicity costs were $131.64 (standard error [SE] = $23.68). Most frequently incurred expenditures were new undergarments and products to manage toxicity. Education was a significant unique predictor of spending, with more educated women spending more money. Greater functioning impairment was associated with greater costs. The STC proved to be a practical, brief measure which successfully indicated specific areas of patient expenditures and need. Results reveal the nonmedical, out-of-pocket costs associated with acute skin toxicity in the context of breast cancer radiotherapy. To our knowledge, this study is the first to quantify individual costs associated with this treatment side effect, as well as the first to present a scale specifically designed to assess such costs. In future research, the STC could be used as an outcome variable in skin toxicity prevention and control research, as a behavioral indicator of symptom burden, or as part of a needs assessment.

Atherosclerosis is a systemic inflammatory disease that may affect multiple arterial beds simultaneously. Vascular distensibility is increasingly used in the clinical assessment of patients with atherosclerotic disease. In this study, we assess distensibility of symptomatic atherosclerotic carotid artery and of contralateral asymptomatic side. We also investigate the distensibility of bilaterally asymptomatic atherosclerotic carotid arteries using cine phase-contrast carotid magnetic resonance (MR) imaging. Nineteen patients with bilateral carotid artery disease underwent cine phase-contrast carotid imaging on a 1.5 T MR system. Ten patients had ipsilateral symptomatic carotid artery disease and contralateral asymptomatic stenosis. Nine additional patients with bilateral asymptomatic carotid artery disease constituted historical control group. Cine phase-contrast MR imaging acquired at the common carotid artery, maximum luminal stenosis, and internal carotid artery was used to determine carotid distensibility bilaterally for carotid arteries in both patient groups. Symptomatic carotid arteries were found to be significantly less distensible (mean distensibility coefficient [DC] 35.4 ± 6.12 × 10(-3)/kPa) than the contralateral asymptomatic vessels (mean DC 54.4 ± 7.88 × 10(-3)/kPa, P = .03) at the level of the common carotid artery. A similar trend of high distensibility for asymptomatic side in the area of maximum stenosis and the internal carotid artery was seen, but it was not found to be statistically significant. Plaque burden was comparable between the 2 groups at all locations. DC was comparable for patients with bilateral asymptomatic carotid artery stenoses. Distensibility of bilaterally asymptomatic carotid arteries was greater than that of asymptomatic carotid artery contralateral to the symptomatic side. Symptomatic carotid artery is stiffer than the contralateral asymptomatic side, despite comparable plaque burden. Patients with bilateral asymptomatic carotid artery disease have comparable stiffness. Larger studies are warranted to further investigate the findings of this MR study.

Chronic low-grade inflammation plays a pivotal role in the pathogenesis of obesity, due to its associated chronic diseases such as type II diabetes, cardiovascular diseases, pulmonary diseases and cancer. Thus, targeting inflammation is an attractive strategy to counter the burden of obesity-induced health problems. Recently, food-derived bioactive compounds have been spotlighted as a regulator against various chronic diseases due to their low toxicity, as opposed to drugs that induce severe side effects. Here we describe the beneficial effects of dietary anthocyanins on obesity-induced metabolic disorders and inflammation. Red cabbage microgreen, blueberry, blackcurrant, mulberry, cherry, black elderberry, black soybean, chokeberry and jaboticaba peel contain a variety of anthocyanins including cyanidins, delphinidins, malvidins, pelargonidins, peonidins and petunidins, and have been reported to alter both metabolic markers and inflammatory markers in cells, animals, and humans. This review discusses the interplay between inflammation and obesity, and their subsequent regulation via the use of dietary anthocyanins, suggesting an alternative dietary strategy to ameliorate obesity and obesity associated chronic diseases.

Tourism, next to telecommunication and computer science, is one of the most dynamically developing branches of economic activity and it brings significant profits. World Tourism and Travel Council has been pointing out the fact that while judging the economic effects of tourism, not only the direct revenue from this branch should be taken into account, but also all kind of side effects, which influence the economic development. During past years in Poland, the responsibility burden of tourist development was moved from national to the level of local government, which began to be an independent economic entity, responsible for its actions and managing the municipality's economy. Development strategy began to be one of the essential documents in the process of planning and prediction of the development direction of territorial structure and tourist product. Not only is it the most comprehensive compendium of the information concerning the region, but also it points out its strengths and prospects, identifies the weaknesses and threats and determines targets and execution schedule.

This review discusses the interplay between inflammation and obesity, and their subsequent regulation via the use of dietary anthocyanins, suggesting an alternative dietary strategy to ameliorate obesity and obesity associated chronic diseases.

Intrauterine Growth Restriction: Hungry for an Answer

PubMed Central

Chu, Alison

2016-01-01

Intrauterine growth restriction (IUGR) has been defined in several ways, but in general describes a condition in which the fetus exhibits poor growth in utero. This complication of pregnancy poses a significant public health burden as well as increased morbidity and mortality for the offspring. In human IUGR, alteration in fetal glucose and insulin homeostasis occurs in an effort to conserve energy and survive at the expense of fetal growth in an environment of inadequate nutrient provision. Several animal models of IUGR have been utilized to study the effects of IUGR on fetal glucose handling, as well as the postnatal reprogramming of energy metabolite handling, which may be unmasked in adulthood as a maladaptive propensity for cardiometabolic disease. This developmental programming may be mediated in part by epigenetic modification of essential regulators of glucose homeostasis. Several pharmacological therapies and nonpharmacological lifestyle modifications have shown early promise in mitigating the risk for or severity of adult metabolic phenotypes but still require further study of unanticipated and/or untoward side effects.

Chemotherapy induced nausea and vomiting (CINV) are major side effects of chemotherapy and a great burden to patients' quality of life. Serotonin and substance P are the major neurotransmitters involved in the pathophysiology of CINV, but in spite of new antiemetics no completely effective regime exists for its prevention or treatment. Areas covered: In this review the authors provide a detailed description of granisetron's chemistry pharmacokinetics, pharmacodynamics, toxicity and a brief review of clinical trials involving granisetron and the management of CINV. We searched reviews, meta-analysis and randomized controlled trials (Medline, Embase and article reference lists). Expert opinion: According to current literature, granisetron 2 mg orally or 0,01mg/kg (1 mg) intravenously per day, co-administered with dexamethasone and NK-1 antagonists is the recommended regime for highly emetogenic chemotherapy. In the future the role of transdermal and subcutaneous formulations against delayed CINV will be clarified and probably enhance patients' convenience.

Berry Fruit Consumption and Metabolic Syndrome

Metabolic Syndrome is a cluster of risk factors which often includes central obesity, dyslipidemia, insulin resistance, glucose intolerance, hypertension, endothelial dysfunction, as well as a pro-inflammatory, pro-oxidant, and pro-thrombotic environment. This leads to a dramatically increased risk of developing type II diabetes mellitus and cardiovascular disease, which is the leading cause of death both in the United States and worldwide. Increasing evidence suggests that berry fruit consumption has a significant potential in the prevention and treatment of most risk factors associated with Metabolic Syndrome and its cardiovascular complications in the human population. This is likely due to the presence of polyphenols with known antioxidant and anti-inflammatory effects, such as anthocyanins and/or phenolic acids. The present review summarizes the findings of recent dietary interventions with berry fruits on human subjects with or at risk of Metabolic Syndrome. It also discusses the potential role of berries as part of a dietary strategy which could greatly reduce the need for pharmacotherapy, associated with potentially deleterious side effects and constituting a considerable financial burden.

Cancer is a major health burden worldwide, and despite continuous advances in medical therapies, resistance to standard drugs and adverse effects still represent an important cause of therapeutic failure. There is a growing evidence that gut bacteria can affect the response to chemo- and immunotherapeutic drugs by modulating either efficacy or toxicity. Moreover, intratumor bacteria have been shown to modulate chemotherapy response. At the same time, anticancer treatments themselves significantly affect the microbiota composition, thus disrupting homeostasis and exacerbating discomfort to the patient. Here, we review the existing knowledge concerning the role of the microbiota in mediating chemo- and immunotherapy efficacy and toxicity and the ability of these therapeutic options to trigger dysbiotic condition contributing to the severity of side effects. In addition, we discuss the use of probiotics, prebiotics, synbiotics, postbiotics, and antibiotics as emerging strategies for manipulating the microbiota in order to improve therapeutic outcome or at least ensure patients a better quality of life all along of anticancer treatments.

Future directions in lipid therapies.

Cholesterol management to reduce the burden of cardiovascular disease is a major public health concern. Despite widespread recognition of lipid abnormalities as cardiovascular risk factors, significant cardiovascular event reductions with cholesterol-lowering therapies, and dissemination of treatment guidelines, most high-risk patients are not at target lipid levels. In addition to lifestyle changes, four major drug classes are available to modify lipid levels: fibrates, niacin, resins, and statins. High efficacy and tolerability in clinical trials make statins the most widely prescribed of these agents. Newer, more potent members of this class and novel formulations of niacin and resins may provide more effective therapy for dyslipidemia with fewer side effects. Several agents in development (cholesterol-absorption inhibitors and ACAT inhibitors) exploit mechanisms of action complementary to those of current treatments and combined with statins may produce greater improvements in lipid profiles than are now possible. These innovations should enable a greater number of patients to achieve more aggressive cholesterol goals, thereby reducing the risk of cardiovascular events.

Melatonin and Fertoprotective Adjuvants: Prevention against Premature Ovarian Failure during Chemotherapy

PubMed Central

Jang, Hoon; Hong, Kwonho; Choi, Youngsok

2017-01-01

Premature ovarian failure is one of the side effects of chemotherapy in pre-menopausal cancer patients. Preservation of fertility has become increasingly important in improving the quality of life of completely recovered cancer patients. Among the possible strategies for preserving fertility such as ovarian tissue cryopreservation, co-treatment with a pharmacological adjuvant is highly effective and poses less of a burden on the human body. Melatonin is generally produced in various tissues and acts as a universally acting antioxidant in cells. Melatonin is now more widely used in various biological processes including treating insomnia and an adjuvant during chemotherapy. In this review, we summarize the information indicating that melatonin may be useful for reducing and preventing premature ovarian failure in chemotherapy-treated female patients. We also mention that many adjuvants other than melatonin are developed and used to inhibit chemotherapy-induced infertility. This information will give us novel insights on the clinical use of melatonin and other agents as fertoprotective adjuvants for female cancer patients. PMID:28590419

Why Targeted Therapies are Necessary for Systemic Lupus Erythematosus

Durcan, Laura; Petri, Michelle

2016-01-01

Systemic lupus erythematosus (SLE) continues to have important morbidity and accelerated mortality despite therapeutic advances. Targeted therapies offer the possibility of improved efficacy with fewer side-effects. Current management strategies rely heavily on non-specific immunosuppressive agents. Prednisone, in particular, is responsible for a considerable burden of later organ damage. There are a multitude of diverse mechanisms of disease activity, immunogenic abnormalities and clinical manifestations to take into consideration in SLE. Many targeted agents with robust mechanistic pre-clinical data and promising early phase studies have ultimately been disappointing in phase III randomized controlled studies. Recent efforts have focused on B cell therapies, in particular given the success of belimumab in clinical trials, with limited success. We remain optimistic regarding other specific therapies being evaluated including interferon alpha blockade. It is likely that in SLE, given the heterogeneity of the population involved, precision medicine is needed, rather than expecting that any single biologic will be universally effective.

Diagnosis and Treatment of Dyssynergic Defecation

PubMed Central

Rao, Satish S C; Patcharatrakul, Tanisa

2016-01-01

Dyssynergic defecation is common and affects up to one half of patients with chronic constipation. This acquired behavioral problem is due to the inability to coordinate the abdominal and pelvic floor muscles to evacuate stools. A detailed history, prospective stool diaries, and a careful digital rectal examination will not only identify the nature of bowel dysfunction, but also raise the index of suspicion for this evacuation disorder. Anorectal physiology tests and balloon expulsion test are essential for a diagnosis. Newer techniques such as high-resolution manometry and magnetic resonance defecography can provide mechanistic insights. Recently, randomized controlled trials have shown that biofeedback therapy is more effective than laxatives and other modalities, both in the short term and long term, without side effects. Also, symptom improvements correlated with changes in underlying pathophysiology. Biofeedback therapy has been recommended as the first-line of treatment for dyssynergic defecation. Here, we provide an overview of the burden of illness and pathophysiology of dyssynergic defecation, and how to diagnose and treat this condition with biofeedback therapy. PMID:27270989

The debate: Treatment after the first seizure - The CONTRA.

PubMed

Steinhoff, Bernhard J

2017-07-01

In many instances antiepileptic drug (AED) treatment of epilepsy patients is sustained for a long time and is even a lifelong therapy. Chronic drug treatment naturally means the potential burden of adverse effects. The prognosis to remain seizure-free is good after a first seizure even without AEDs. Therefore one has to consider the possibility that freedom from seizures when AED treatment has been initiated after the first seizure may not in fact be the result of the AED treatment. On the other hand seizure-free patients without severe side effects most probably will not consider discontinuing AEDs. Therefore in these cases it will not be possible to discover whether AEDs are really necessary to maintain freedom from seizures. Furthermore it has been shown that the long-term prognosis is independent of whether AED treatment started after the first or a following seizure. Therefore in most instances AED treatment after a first seizure should be avoided. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

A Brief Motivational Intervention for Preventing Medication-Associated Weight Gain Among Youth with Bipolar Disorder: Treatment Development and Case Report

Goldstein, Benjamin I.; Mantz, Michael B.; Bailey, Bridget; Douaihy, Antoine

2011-01-01

Abstract Bipolar disorder (BP) in youth is an impairing psychiatric disorder associated with high rates of relapse and recurrence. High rates of psychiatric and medical co-morbidities account for additional illness burden in pediatric BP. The elevated risk of overweight and obesity in this population is of particular concern. One of the likely etiologies for weight gain in youth with BP is use of mood-stabilizing medications. Although these medications can be effective for mood stabilization, excessive weight gain is a common side effect. Obesity is associated with a host of medical problems and is also correlated with worse psychiatric outcomes in BP, rendering the prevention of weight gain in this population particularly clinically relevant. In this article, we describe the rationale and development of a brief motivational intervention for preventing weight gain among youth with BP initiating mood-stabilizing pharmacological treatment and then present a case example illustrating the principles of the intervention.

Chronic pain resulting from inflammatory and neuropathic disorders causes considerable economic and social burden. Pharmacological therapies currently available for certain types of pain are only partially effective and may cause severe adverse side effects. The C5a anaphylatoxin acting on its cognate G protein-coupled receptor (GPCR), C5aR, is a potent pronociceptive mediator in several models of inflammatory and neuropathic pain. Although there has long been interest in the identification of C5aR inhibitors, their development has been complicated, as for many peptidomimetic drugs, mostly by poor drug-like properties. Herein, we report the de novo design of a potent and selective C5aR noncompetitive allosteric inhibitor, DF2593A, guided by the hypothesis that an allosteric site, the "minor pocket," previously characterized in CXC chemokine receptors-1 and -2, is functionally conserved in the GPCR class. In vitro, DF2593A potently inhibited C5a-induced migration of human and rodent neutrophils. In vivo, oral administration of DF2593A effectively reduced mechanical hyperalgesia in several models of acute and chronic inflammatory and neuropathic pain, without any apparent side effects. Mechanical hyperalgesia after spared nerve injury was also reduced in C5aR(-/-) mice compared with WT mice. Furthermore, treatment of C5aR(-/-) mice with DF2593A did not produce any further antinociceptive effect compared with C5aR(-/-) mice treated with vehicle. The successful medicinal chemistry strategy confirms that a conserved minor pocket is amenable for the rational design of selective inhibitors and the pharmacological results support that the allosteric blockade of the C5aR represents a highly promising therapeutic approach to control chronic inflammatory and neuropathic pain.

Spatial and temporal variations in cadmium concentrations and burdens in the Pacific oyster (Crassostrea gigas) sampled from the Pacific north-west.

PubMed

Bendell, Leah I; Feng, Cindy

2009-08-01

Oysters from the north-west coast of Canada contain high levels of cadmium, a toxic metal, in amounts that exceed food safety guidelines for international markets. A first required step to determine the sources of cadmium is to identify possible spatial and temporal trends in the accumulation of cadmium by the oyster. To meet this objective, rather than sample wild and cultured oysters of unknown age and origin, an oyster "grow-out" experiment was initiated. Cultured oyster seed was suspended in the water column up to a depth of 7 m and the oyster seed allowed to mature a period of 3 years until market size. Oysters were sampled bimonthly and at time of sampling, temperature, chlorophyll-a, turbidity and salinity were measured. Oyster total shell length, dry tissue weights, cadmium concentrations (microg g(-1)) and burdens (microg of cadmium oyster(-1)) were determined. Oyster cadmium concentrations and burdens were then interpreted with respect to the spatial and temporal sampling design as well as to the measured physio-chemical and biotic variables. When expressed as a concentration, there was a marked seasonality with concentrations being greater in winter as compared in summer; however no spatial trend was evident. When expressed as a burden which corrects for differences in tissue mass, there was no seasonality, however cadmium oyster burdens increased from south to north. Comparison of cadmium accumulation rates oyster(-1) among sites indicated three locations, Webster Island, on the west side of Vancouver Island, and two within Desolation Sound, Teakerne Arm and Redonda Bay, where point sources of cadmium which are not present at all other sampling locations may be contributing to overall oyster cadmium burdens. Of the four physio-chemical factors measured only temperature and turbidity weakly correlated with tissue cadmium concentrations (r(2)=-0.13; p<0.05). By expressing oyster cadmium both as concentration and burden, regional and temporal patterns were demonstrated, which may have been missed if just concentration was determined.

The burden of caring for an older adult can be a form of stress and influence caregivers' daily lives and health. Previous studies have reported that resilience and social support play an important role in reducing physical and psychological burden in caregivers. Thus, the present study aimed to examine whether perceived social support served as a possible protective factor of burden among caregivers of older adults in Singapore using moderation and mediation effects' models. We conducted a cross-sectional study with 285 caregivers providing care to older adults aged 60 years and above who were diagnosed with physical and/or mental illness in Singapore. The Connor-Davidson Resilience Scale (CD-RISC) was used to measure resilience and burden was measured by the Zarit Burden Interview (ZBI). The Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure perceived social support. Hayes' PROCESS macro was used to test moderation and mediation effects of perceived social support in the relationship between resilience and burden after controlling for sociodemographic variables. Indirect effects were tested using bootstrapped confidence intervals (CI). The mean scores observed were CD-RISC: 70.8/100 (SD = 15.1), MSPSS: 62.2/84 (SD = 12.2), and ZBI: 23.2/88 (SD = 16.0) respectively. While perceived social support served as a full mediator between resilience and caregiver burden (β = - 0.14, 95% CI -0.224 to - 0.072, p < 0.05), it did not show a significant moderating effect. Perceived social support mediates the association between resilience and caregiver burden among caregivers of older adults in Singapore. It is crucial for healthcare professionals, particularly those who interact and deliver services to assist caregivers, to promote and identify supportive family and friends' network that may help to address caregiver burden.

Relationship between Mental Health and Burden among Primary Caregivers of Outpatients with Schizophrenia.

There is growing recognition that caring for a patient with schizophrenia often results in high levels of perceived burden and poorer overall mental health for caregivers. A quantitative cross-sectional design and standardized instruments were used to collect data from 355 primary caregivers of adults in outpatient care with schizophrenia in China. Structural equation modeling was used to examine the association between caregiver burden and mental health among primary caregivers and whether this association is influenced by personality, coping style, and family functioning, based on a diathesis-stress perspective. Goodness-of-fit indices (χ 2 /df = 1.406, GFI = 0.919, CFI = 0.957, etc.) confirmed that the modified model fit the data well. In line with the diathesis-stress model, and with this study's hypotheses, we found that caregiver burden was significantly related to mental health outcomes directly. The final model showed that personality traits, coping style, and family function influenced the relationship between caregiver burden and mental health. The neuroticism personality traits have a direct effect on caregiver burden and family functioning in this sample. Coping style had a direct effect on the caregiver burden, and family functioning had a direct effect on the caregiver burden. Our final model about primary caregivers can be applied clinically to predict mental health outcomes from caregiver burden. © 2018 Family Process Institute.

2013-01-01

Abstract Background The use of silver for the treatment of various maladies or to prevent the transmission of infection dates back to at least 4000 b.c.e. Medical applications are documented in the literature throughout the 17th and 18th centuries. The bactericidal activity of silver is well established. Silver nitrate was used topically throughout the 1800s for the treatment of burns, ulcerations, and infected wounds, and although its use declined after World War II and the advent of antibiotics, Fox revitalized its use in the form of silver sulfadiazine in 1968. Method Review of the pertinent English-language literature. Results Since Fox's work, the use of topical silver to reduce bacterial burden and promote healing has been investigated in the setting of chronic wounds and ulcers, post-operative incision dressings, blood and urinary catheter designs, endotracheal tubes, orthopedic devices, vascular prostheses, and the sewing ring of prosthetic heart valves. The beneficial effects of silver in reducing or preventing infection have been seen in the topical treatment of burns and chronic wounds and in its use as a coating for many medical devices. However, silver has been unsuccessful in certain applications, such as the Silzone heart valve. In other settings, such as orthopedic hardware coatings, its benefit remains unproved. Conclusion Silver remains a reasonable addition to the armamentarium against infection and has relatively few side effects. However, one should weigh the benefits of silver-containing products against the known side effects and the other options available for the intended purpose when selecting the most appropriate therapy.

Although improvements in perioperative care have decreased surgical morbidity after radical cystectomy for muscle invasive bladder cancer, treatment side effects still have a negative impact on patient quality of life. We examined unmet patient needs along the illness trajectory. A total of 30 patients (26.7% women) treated with cystectomy and urinary diversion for muscle invasive bladder cancer participated in the study. Patients were recruited from the Department of Urology at Mount Sinai and through advertisements on the Bladder Cancer Advocacy Network (BCAN) website between December 2011 and September 2012. Data were collected at individual interviews, which were audiotaped and transcribed. Transcribed data were quantitatively analyzed to explore key unmet needs. At diagnosis unmet informational needs were predominant, consisting of insufficient discussion of certain topics, including urinary diversion options and their side effects, self-care, the recovery process and medical insurance. Unmet psychological needs related to depression, and worries about changes in body image and sexual function were reported. Postoperative unmet needs revolved around medical needs (eg pain and bowel dysfunction) and instrumental needs (eg need of support for stomal appliances, catheters and incontinence). During survivorship (ie 6 to 72 months postoperatively) unmet needs centered around psychological support (ie depression, poor body image and sexual dysfunction) and instrumental support (eg difficulty adjusting to changes in daily living). Meeting patient needs is imperative to ensure adequate patient involvement in health care and enhance postoperative quality of life. An effective support provision plan should follow changes in patient needs. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Experimental Validation of a Fast Forward Model for Guided Wave Tomography of Pipe Elbows.

Brath, Alex J; Simonetti, Francesco; Nagy, Peter B; Instanes, Geir

2017-05-01

Ultrasonic guided wave tomography (GWT) methods for the detection of corrosion and erosion damage in straight pipe sections are now well advanced. However, successful application of GWT to pipe bends has not yet been demonstrated due to the computational burden associated with the complex forward model required to simulate guided wave propagation through the bend. In a previous paper [Brath et al., IEEE Trans. Ultrason., Ferroelectr., Freq. Control, vol. 61, pp. 815-829, 2014], we have shown that the speed of the forward model can be increased by replacing the 3-D pipe bend with a 2-D rectangular domain in which guided wave propagation is formulated based on an artificially inhomogeneous and elliptically anisotropic (INELAN) acoustic model. This paper provides further experimental validation of the INLEAN model by studying the traveltime shifts caused by the introduction of shallow defects on the elbow of a pipe bend. Comparison between experiments and simulations confirms that a defect can be modeled as a phase velocity perturbation to the INLEAN velocity field with accuracy that is within the experimental error of the measurements. In addition, it is found that the sensitivity of traveltime measurements to the presence of damage decreases as the damage position moves from the interior side of the bend (intrados) to the exterior one (extrados). This effect is due to the nonuniform ray coverage obtainable when transmitting the guided wave signals with one ring array of sources on one side of the elbow and receiving with a second array on the other side.

Molecular Imaging of Neuropsychiatric Symptoms in Alzheimer’s and Parkinson’s disease

2015-01-01

Neuropsychiatric symptoms (NPS) are very common in neurodegenerative diseases and are a major contributor to disability and caregiver burden. There is accumulating evidence that NPS may be a prodrome of neurodegenerative diseases and are associated with functional decline. The medications used to treat these symptoms in younger patients are not very effective in patients with neurodegenerative disease and may have serious side effects. An understanding of the neurobiology of NPS is critical for the development of more effective intervention strategies. Targeting these symptoms may also have implications for prevention of cognitive or motor decline. Molecular brain imaging represents a bridge between basic and clinical observations and provides many opportunities for translation from animal models and human post-mortem studies to in vivo human studies. Molecular brain imaging studies in Alzheimer’s disease (AD) and Parkinson’s disease (PD) are reviewed with a primary focus on positron emission tomography studies of NPS. Future directions for the field of molecular imaging in AD and PD to understand the neurobiology of NPS will be discussed. PMID:25446948

Candidiasis is one of the most common opportunistic fungal infections caused by genus Candida. The genus composed of around 200 species. The most virulent among all are, Candida albicans followed by various non-albicans species. Despite of various treatments available, the incidence of severe systemic fungal infections is increasing, and with it the related morbidity and mortality, in relation to the misuse of antimicrobials and the emergence of drug-resistant fungal species. Therefore, various novel therapeutic approaches need to be developed and explored to overcome these limitations and effective management of candidiasis. In this review, we focused on natural herbal remedies and significance of novel formulation approaches for the treatment of candidiasis. The reported studies suggested the promising role of phytomedicines and novel polymeric drug delivery systems in therapeutic management of candidiasis. Phytomedicines are effective substitute of synthetic drugs as they are inexpensive with lesser number of side effects. Various novel particulate approaches can be successfully used to reduce the fungal burden at the target site.

Treatment of schizophrenia and major depressive disorder (MDD) with atypical antipsychotics (AAPs) show improved efficacy and reduced side effect burden compared with older antipsychotic medications. However, a risk of treatment-emergent adverse events (TEAEs) remains. TEAEs are hard to quantify and perspectives on the importance of TEAEs differ across patients and between patients and physicians. The current study is a qualitative assessment that investigates TEAEs of AAPs from both patient and physician perspectives to provide better understanding of the occurrence and burden of TEAEs associated with these medications. Focus groups comprised of patients with MDD and interviews with patients with schizophrenia were conducted at two qualitative research facilities, along with a physician focus group at one of the facilities. Information collected from patients included an exhaustive list of TEAEs experienced, and the frequency and level of bother of each TEAE; from psychiatrists, information included an exhaustive list of TEAEs based on personal observations and patient report, frequency of TEAEs, clinically important TEAEs, and levels of patient-perceived bother. Standard qualitative analysis methods were used to identify, quantify, characterize, and summarize patterns found in the data collected. A total of 42 patients (25 with MDD and 17 with schizophrenia) and 4 psychiatrists participated in the study. TEAEs reported as bothersome across both patients groups included cognitive issues, weight gain and/or increased appetite, low energy, extrapyramidal symptoms (EPS), and need to sleep/excessive sleep/excessive sleepiness. TEAEs considered more bothersome by patients with schizophrenia were weight gain, low energy, EPS, mental anxiety, and increased positive symptoms; those considered more bothersome by patients with MDD were cognitive issues, somnolence/sedation, and flat/restricted affect. TEAEs considered most clinically important by psychiatrists included metabolic syndrome, weight gain, neutropenia, hyperglycemia, and QT prolongation; those TEAEs considered most bothersome to patients from physicians' perspectives included weight gain, reduced sexual desire or performance, EPS, akathisia, and hormonal issues. The wide range of TEAEs that are both frequent and bothersome and the variation in perceived burden according to diagnosis highlight the need for a tailored TEAE-awareness approach when choosing an AAP.

Patients requiring chronic blood transfusions are at risk for iron overload, which, if not treated by iron chelation therapy (ICT), can create serious organ damage and reduce life expectancy. Current ICT requires burdensome 8- to 12-hour infusions five to seven times per week. A naturalistic study of the burden of infused ICT was conducted in four US centers. Data from the initial and most recent years of ICT were collected from medical charts of consenting thalassemia (n = 40) and sickle cell disease (n = 9) patients. Quality of life (QoL), treatment satisfaction, and ICT-related resource utilization data were also collected from a patient interview. Mean serum ferritin levels during the initial (2519 +/- 1382 ng/mL) and most recent (2741 +/- 2532 ng/mL) years remained unacceptably high and increased over time (306 +/- 2200 ng/mL; mean of 20+/- years of therapy). Within 30 days before interview, 55 percent of patients suffered at least one ICT-related adverse event; 76 percent missed at least one dose. QoL, measured by the SF-36, and treatment satisfaction appear compromised in this cohort. Although total annual costs of ICT were estimated at USD $30,000 to $35,000, drug accounted for only 50 to 60 percent of this amount. Infused ICT may not provide adequate effectiveness in the real world. High ferritin levels seem to be associated with ICT noncompliance, likely in relation to the bothersome mode of administration and side effects. The total cost of ICT appears to well exceed that of drug alone.

Hepatocellular carcinoma (HCC) ranks second in cancer mortality and has limited therapeutic options. We recently described the synergistic effect of allosteric and ATP-site competitive inhibitors against the mammalian target of rapamycin (mTOR) for the treatment of HCC. However, such inhibitors induce glycemia and increase mitochondrial efficiency. Here we determined whether the mitochondrial complex I inhibitor Phenformin could reverse both side effects, impose an energetic-stress on cancer cells and suppress the growth of HCC. Human HCC cell lines were used in vitro to access the signaling and energetic impact of mTOR inhibitors and Phenformin, either alone or in combination. Next, the therapeutic utility of these drugs alone or in combination was investigated pre-clinically in human orthotopic tumors implanted in mice, by analyzing their impact on the tumor burden and overall survival. We found Phenformin caused mitochondrial dysfunction and fragmentation, inducing a compensatory shift to glycolysis. In contrast, dual inhibition of mTOR impaired cell growth and glycolysis, while increasing mitochondrial fusion and efficiency. In a mouse model of human HCC, dual inhibition of mTOR, together with Phenformin, was highly efficacious in controlling tumor burden. However, more striking, pretreatment with Phenformin sensitized tumors to dual inhibition of mTOR, leading to a dramatic improvement in survival. Treatment of HCC cells in vitro with the biguanide Phenformin causes a metabolic shift to glycolysis, mitochondrial dysfunction and fragmentation, and dramatically sensitizes orthotopic liver tumors to dual inhibition of mTOR. We therefore propose this therapeutic approach should be tested clinically in HCC. Copyright ©2018, American Association for Cancer Research.

Blockade of CD44 is considered a therapeutic option for the elimination of leukemia-initiating cells. However, the application of anti-panCD44 can be burdened by severe side effects. We determined whether these side effects could be avoided by replacing anti-panCD44 with CD44 variant isoform (CD44v)-specific antibodies in CD44v-positive hematological malignancies using the EL4 thymoma and CD44v10-transfected EL4 (EL4-v10) as models. Subcutaneous growth of EL4 and EL4-v10 was equally well inhibited by the anti-panCD44 and anti-CD44v10 antibodies, respectively. Ex vivo analysis indicated that natural killer cytotoxicity and antibody-dependent cellular cytotoxicity were the main effector mechanisms. Under local inflammation, the efficacy of anti-CD44v10 prolonged the survival time twofold compared with untreated, EL4-v10 tumor-bearing mice, and this was due to inflammation-induced expression of osteopontin (OPN). A high level of OPN in EL4-v10 tumors supported leukocyte recruitment and tumor-infiltrating T-cell activation. Taken together, in hematological malignancies expressing CD44v, anti-panCD44 can be replaced by CD44v-specific antibodies without a loss in efficacy. Furthermore, CD44v10-specific antibodies appear particularly advantageous in cutaneous leukemia therapy, as CD44v10 binding of OPN drives leukocyte recruitment and activation.

Carrier-added [(123)I]-2-iodo-D-phenylalanine (CA [(123)I]-2-I-D-Phe) was previously found to have a preferential retention in tumors with a high tumor background contrast in animal models. A previous human dosimetry study demonstrated a favorable biodistribution and radiation burden in human subjects. The aim of this study was to investigate the potential of CA [(131)I]-2-I-D-Phe as an agent for radionuclide therapy. Sixty (60) nude athymic mice were inoculated subcutaneously with firefly luciferase-transduced R1M rhabdomyosarcoma cells. The mice in the therapy group were injected intravenously (i.v.) with 148 MBq [(131)I]-2-I-D-Phe (432 GBq/mmol) in kit solution. Controls were injected with kit solution without radioactivity, with physiological saline, or with 148 MBq [(131)I](-) in physiological saline. Tumor growth was quantified using bioluminescent imaging and caliper measurements. [(131)I]-2-I-D-Phe clearly reduced tumor growth in the treated mice compared with the control groups. A tumor growth-rate reduction of at least 33% was found for mice receiving a therapeutic dose. There were no serious adverse side-effects of the therapy. In conclusion, i.v. injection of CA 148 MBq [(131)I]-2-I-D-Phe specifically reduces tumor growth in athymic nude mice without relevant side-effects on the animals' health.

The aim was to identify significant relationships between the 21 components of caregivers' sense of burden in the Zarit Burden Interview and specific paid care services provided in Japan's long-term care insurance system. We defined a service utilization level (SUL) that represents the amount of care services that caregivers were consuming. We calculated the ratios of people, among those with the same SUL value, whose sense of burden was weaker than a specific level. Finally, we conducted regression analysis and checked how this ratio varied compared to the change in SUL values. For 12 among 22 components, the use of paid care services in general were significantly and linearly related with a smaller number of people having the strongest sense of burden. Several pairs of burden components and care service types were identified indicating that the type of care services effectively alleviated that burden component. (1) Paid care services do relieve caregivers' sense of burden. (2) Measures to increase the ratio of people with the weakest sense of burden by encouraging the use of care services do not necessarily match those that decrease the ratio of people feeling the heaviest burden. (3) Policies that encourage caregivers to use more care services can be more effective if policy makers know which type of care service is related with a burden component.

Recombinant human IGF-1 currently represents the only available treatment option for the Laron Syndrome, a rare human disorder caused by defects in the gene encoding growth hormone receptor, resulting in irreversibly retarded growth. Unfortunately, this treatment therapy, poorly impacts longitudinal growth (13% in females and 19% in males), while burdening the patients with severe side effects, including hypoglycemia, in association with the unfair chore of taking multiple daily injections that cause local intense pain. In this study, we have demonstrated that a single intraperitoneal graft of microencapsulated pig Sertoli cells, producing pig insulin-like growth factor-1, successfully promoted significant proportional growth in the Laron mouse, a unique animal model of the human Laron Syndrome. These findings indicate a novel, simply, safe and successful method for the cell therapy-based cure of the Laron Syndrome, potentially applicable to humans. Copyright © 2012 Elsevier B.V.

The burden of cardiac side effects in oncology patients will dramatically increase in the near future as a result of the widespread use of anticancer agents affecting the cardiovascular system, the general population aging, the heightened attention in the detection of cardiac toxicity and the absolute gain in terms of overall survival. The relationship between cardiologists and oncologists should therefore be closer leading to the definition of cardio-oncology. The increased number of such patients requires the creation of a dedicated patient assistance program in order to guarantee every patient the possibility of an interdisciplinary and multiprofessional approach. A dedicated care pathway needs a reorganization of internal resources to ensure high standards of care. The proposed pathway is actually active at our institution and has been implemented taking into account available facilities and planned work amount. Our patient cardio-oncology program could be adapted with minimal changes to different hospitals.

About 92.1 million Americans suffer from at least one type of cardiovascular disease. Worldwide, cardiovascular diseases are the number one cause of death (about 31% of all global deaths). Recent technological advancements in cardiac ultrasound imaging are expected to aid in the clinical diagnosis of many cardiovascular diseases. This article provides an overview of such recent technological advancements, specifically focusing on tissue Doppler imaging, strain imaging, contrast echocardiography, 3D echocardiography, point-of-care echocardiography, 3D volumetric flow assessments, and elastography. With these advancements ultrasound imaging is rapidly changing the domain of cardiac imaging. The advantages offered by ultrasound imaging include real-time imaging, imaging at patient bed-side, cost-effectiveness and ionizing-radiation-free imaging. Along with these advantages, the steps taken towards standardization of ultrasound based quantitative markers, reviewed here, will play a major role in addressing the healthcare burden associated with cardiovascular diseases.

2014-08-01

This study aimed to identify caregiver burden and influencing factors on the burden in primary caregivers of peripheral blood stem cell transplantation patients within 2-12 months following transplant, indicating early recovery period after discharge. This descriptive cross sectional study was carried out at hematopoietic stem cell transplantation outpatient units of three university hospitals in Turkey. A total of 55 patient and caregiver dyads were recruited and interviewed. The data were collected using questionnaires developed by the researchers and caregiver burden was measured with the Zarit Burden Interview. The mean score of Zarit Burden Interview was 28.41 (SD = 13.90). Patients' symptoms including nausea and self depreciation feeling were related to greater caregiver burden. Self-depreciation was referred to feeling undervalued. The mean score of the tool was significantly higher in caregivers who have not been educated beyond primary school and also caregivers who had lower income. Caregivers who supported their patients to fulfill physical needs and who did not receive help for meeting patients' psychological needs had statistically more elevated levels of burden. Moreover, the extent of care giving activities undertaken was positively correlated with caregiver burden scores. While positive impact of the care giving process on family relations decreased caregiver burden; negative effect increased the burden. This study suggests that caregiver burden of primary caregivers caring for peripheral blood stem cell transplantation patients varies by education, income status, and the extent of care giving activities undertaken. Changes in family ties and relations due to care giving effected caregiver burden. Copyright © 2014 Elsevier Ltd. All rights reserved.

The burden on informal caregivers of people with bipolar disorder.

Caregivers of people with bipolar disorder may experience a different quality of burden than is seen with other illnesses. A better understanding of their concerns is necessary to improve the training of professionals working with this population. Conceptualizing caregiver burden in a conventional medical framework may not focus enough on issues important to caregivers, or on cultural and social issues. Perceptions of caregivers about bipolar disorder have important effects on levels of burden experienced. It is important to distinguish between caregivers' experience of this subjective burden and objective burden as externally appraised. Caregivers' previous experiences of health services may influence their beliefs about the illness. Caregiver burden is associated with depression, which affects patient recovery by adding stress to the living environment. The objective burden on caregivers of patients with bipolar disorder is significantly higher than for those with unipolar depression. Caregivers of bipolar patients have high levels of expressed emotion, including critical, hostile, or over-involved attitudes. Several measures have been developed to assess the care burden of patients with depressive disorders, but may be inappropriate for patients with bipolar disorder because of its cyclical nature and the stresses arising from manic and hypomanic episodes. Inter-episode symptoms pose another potential of burden in patients with bipolar disorder. Subsyndromal depressive symptoms are common in this phase of the illness, resulting in severe and widespread impairment of function. Despite the importance of assessing caregiver burden in bipolar disorder, relevant literature is scarce. The specific effects of mania and inter-episode symptoms have not been adequately addressed, and there is a lack of existing measures to assess burden adequately, causing uncertainty regarding how best to structure family interventions to optimally alleviate burden. The relatively few studies into caregiver burden in bipolar disorder may largely reflect experiences in the US Veterans Affairs health service, but the findings may be limited in their generalizability. Nevertheless, available data suggest that caregiver burden is high and largely neglected in bipolar disorder. Clinically effective, well-targeted and practically viable interventions are needed. However, services cannot be enhanced on a rational basis without an improved understanding and capacity to measure and target caregiver burden the impact of any change in services be evaluated.

Tobacco smoke is known to affect plasma levels of some drugs, including the antipsychotic clozapine. The effects of suddenly stopping smoking on patients who take clozapine can be severe, as plasma concentrations are expected to rapidly rise, potentially leading to toxicity. A ban on smoking at South London and the Maudsley NHS Foundation Trust (SLaM) was implemented in 2014, and this was expected to affect the plasma concentrations of clozapine for inpatients at the time. This study aimed to determine whether plasma concentrations of clozapine were affected, and additionally, in line with observations from other authors, whether levels of reported violence would also be affected. The smoking habits of all patients at SLaM who smoked and were prescribed clozapine were recorded both before and after the ban. The Glasgow Antipsychotic Side Effect Scale for Clozapine (GASS-C) scale was used to evaluate side-effect burden. Clozapine doses and plasma concentrations were also collected. In total, 31 patients were included in this study. The mean clozapine dose before the ban was 502 mg/day, and this did not change significantly after the ban. Similarly, there were no significant changes in clozapine or norclozapine plasma concentrations, or in GASS-C scores. There was no change in the amount of tobacco patients reported smoking before or after the ban. A modest but statistically significant reduction in violent incidences was observed. Our data suggest that a ban on smoking for patients taking clozapine on open wards at inpatient hospital sites had little impact on clozapine plasma concentrations, because patients continued to smoke tobacco if allowed to leave. Smoking bans may result in a reduction in violent incidences.

Among aging parents (mean age = 65, N = 139) of adults with developmental disabilities, we examined the effectiveness of multiple forms of coping with caregiver burden. As expected, accommodative strategies of adapting to stress (secondary engagement), used frequently in later life, buffered the impact of caregiver burden, whereas disengagement and distraction strategies exacerbated the effects of burden on depression symptoms. Most effects were similar for mothers and fathers, and all coping strategies, including active strategies to reduce stress (primary engagement), had greater effects for the parents with co-resident children. Vulnerability to caregiver burden was greatest when the aging parents with co-resident children used disengagement and distraction coping, but those who used engagement coping were resilient.

Living with heart failure patients is a complex situation for family caregivers. Few studies have been conducted to examine the effects of interventional programs to ease this condition. The purpose of this study was to determine the effectiveness of a supportive educative group intervention in reducing family caregivers' burden of caregiving. This randomized clinical trail was conducted at a selective teaching hospital in Isfahan, Iran in 2012. The intervention consisted of four weekly multimedia training sessions of 2 h that included education and family support for 50 family caregivers. Caregiver burden was measured using the Zarit Burden Interview (ZBI). Paired t-test, Student's t-tests, and repeated measures analysis of variance (ANOVA) were used to test for significant differences of the mean scores of burden between the intervention and control groups over a 3-month period. The intervention was successful in reducing caregiver burden over time both at the end of the intervention period (P = 0.000) and 3 months after the intervention (P = 0.000). Nurses and other healthcare providers can use the findings of this study in order to implement effective programs to reduce family caregivers' challenges and to provide them more support.

To evaluate the effects of a psycho-educational intervention on caregiver burden in partners of patients with postoperative heart failure. Since partners of cardiac surgery patients play a significant role in the patient's recovery, it is important to address their needs during hospitalization and after discharge. Forty-two patients with postoperative heart failure and their partners participated in a randomized controlled pilot study. Dyads in the intervention group received psycho-educational support from a multidisciplinary team. Dyads in the control group received usual care. No significant differences were found in the performance of caregiving tasks and perceived caregiver burden in the control versus the intervention group. A pilot study exploring the effects of a psycho-educational intervention in patients and their partners did not reveal significant effects with regard to reduced feelings of burden in partners. Alleviating caregiver burden in partners may need a more intense or specific approach. Copyright © 2015 Elsevier Inc. All rights reserved.

2017-03-01

The burden of narcolepsy is likely the result of 2 main aspects: the clinical difficulties and disability incurred as a direct effect of the disorder and the socioeconomic burden. The clinical burden includes the symptoms, diagnosis, comorbidities, treatment, and even mortality that can be associated with narcolepsy. Lifelong therapy is necessary for these patients. Effective treatment results in long-term benefits from both patient and societal perspectives by improving clinical outcomes, potentially enabling improved education and increased employment and work productivity, and quality of life. Thus, reducing the time to appropriate management results in improved outcomes in these patients. Copyright © 2017 Elsevier Inc. All rights reserved.

Physiopathological approach to infective endocarditis in chronic hemodialysis patients: left heart versus right heart involvement.

PubMed

Bentata, Yassamine

2017-11-01

Infectious endocarditis (IE), a complication that is both cardiac and infectious, occurs frequently and is associated with a heavy burden of morbidity and mortality in chronic hemodialysis patients (CHD). About 2-6% of chronic hemodialysis patients develop IE and the incidence is 50-60 times higher among CHD patients than in the general population. The left heart is the most frequent location of IE in CHD and the different published series report a prevalence of left valve involvement varying from 80% to 100%. Valvular and perivalvular abnormalities, alteration of the immune system, and bacteremia associated with repeated manipulation of the vascular access, particularly central venous catheters, comprise the main factors explaining the left heart IE in CHD patients. While left-sided IE develops in altered valves in a high-pressure system, right-sided IE on the contrary, generally develops in healthy valves in a low-pressure system. Right-sided IE is rare, with its incidence varying from 0% to 26% depending on the study, and the tricuspid valve is the main location. Might the massive influx of pathogenic and virulent germs via the central venous catheter to the right heart, with the tricuspid being the first contact valve, have a role in the physiopathology of IE in CHD, thus facilitating bacterial adhesion? While the physiopathology of left-sided IE entails multiple and convincing mechanisms, it is not the case for right-sided IE, for which the physiopathological mechanism is only partially understood and remains shrouded in mystery.

Objectives. We examined the effects of a manualized care management protocol specifically designed for care managers working with caregivers, the Tailored Caregiver Assessment and Referral® (TCARE®) protocol, on caregiver identity discrepancy, burden, and depressive symptoms. Methods. Preliminary data from a longitudinal, randomized, controlled intervention study with 266 family caregivers served by 52 care managers in 4 states were analyzed using repeated measures random effects regression procedures. Caregivers in the intervention and control groups were repeatedly assessed for up to 9 months on caregiver identity discrepancy, 3 areas of caregiving burden—objective, relationship, and stress burdens; depression; and intention for nursing home placement. Results. We found significant group by time interaction effects for caregiver identity discrepancy, relationship burden, stress burden, depression, and intention for nursing home placement. Caregivers in the intervention group experienced significant improvement on these measures, whereas caregivers in the control group worsened on these measures over time. Discussion. The preliminary findings provide strong support for effectiveness of the TCARE® protocol on improving caregiver well-being and mental health outcomes. PMID:21840840

Resistance Elasticity of Antibiotic Demand in Intensive Care.

PubMed

Heister, Thomas; Hagist, Christian; Kaier, Klaus

2017-07-01

The emergence and spread of antimicrobial resistance (AMR) is still an unresolved problem worldwide. In intensive care units (ICUs), first-line antibiotic therapy is highly standardized and widely empiric while treatment failure because of AMR often has severe consequences. Simultaneously, there is a limited number of reserve antibiotics, whose prices and/or side effects are substantially higher than first-line therapy. This paper explores the implications of resistance-induced substitution effects in ICUs. The extent of such substitution effects is shown in a dynamic fixed effect regression analysis using a panel of 66 German ICUs with monthly antibiotic use and resistance data between 2001 and 2012. Our findings support the hypothesis that demand for reserve antibiotics substantially increases when resistance towards first-line agents rises. For some analyses the lagged effect of resistance is also significant, supporting the conjecture that part of the substitution effect is caused by physicians changing antibiotic choices in empiric treatment by adapting their resistance expectation to new information on resistance prevalence. The available information about resistance rates allows physicians to efficiently balance the trade-off between exacerbating resistance and ensuring treatment success. However, resistance-induced substitution effects are not free of charge. These effects should be considered an indirect burden of AMR. Copyright © 2016 John Wiley & Sons, Ltd.

Caregiver burden may be either a predictor or an outcome of caregiver quality of life (QoL). Patient or caregiver factors that directly affect caregiver QoL, predictors that are simultaneously shared with caregiver burden and QoL, and factors that affect caregiver QoL through caregiver burden are not well understood. This study explored predictors of caregiver QoL and identified whether caregiver burden is a mediator for caregivers of first-time stroke patients. This is a cross-sectional study. We recruited first-time stroke patients who had been discharged from the hospital within 1 year. We screened caregivers with two major inclusion criteria: age > 20 years old and being the family member who provides the most patient-care hours out of all family caregivers. Caregiver burden (Caregiver Strain Index, CSI), QoL (Caregiver Quality of Life Index, CQLI), and patient and caregiver characteristics were assessed with structured questionnaires. Multiple-regression and bootstrap analysis were conducted for data analysis. A total of 126 caregivers completed the questionnaires. Higher caregiver burdens, lower caregiver education level, lower self-rated health, lower monthly family income, and spouses who were responsible for medical fees were significant predictors of lower caregiver QoL. Poor self-rated health and monthly family income of $ 666 USD or below were the strongest predictors of caregiver QoL. Spouses who were responsible for medical fees and lower monthly family income had direct negative effects on caregiver QoL, but these factors exhibited no indirect mediating effect between caregiver characteristics and QoL through caregiver burden as a mediator. Caregiver education level at or below elementary school and poor or fair self-rated-health had direct negative effects on caregiver QoL, which were mediated by caregiver burden. Our study indicated predictors of caregiver QoL and the relationships with caregiver burden among first-time stroke survivors in the early stage. Caregivers' financial factors affected caregiver QoL directly. Caregivers' poor self-rated health and lower education level negatively affected caregiver QoL indirectly through caregiver burden as a mediator. Interventions to make appropriate policies for financial subsidies, to enhance caregivers' health and to provide tailored stroke-related education through multidisciplinary cooperation may effectively promote caregiver QoL.

The quantitative study assessed subjective burden, depression, and the moderating effect of social support in mothers of children with autism spectrum disorder (ASD) in India. Seventy mothers were interviewed using a structured interview schedule, which measured their subjective burden, depression, and social support from family, friends, and significant others. Data was analyzed using descriptive statistics and multiple regression analysis with interaction terms. Half of the mothers in the study reported depression of clinical significance. Higher subjective burden significantly predicted higher depression. Of the three sources of support, only medium/high family support had a direct impact on depression and also moderated the impact of the subjective burden of depression. Implications for practice and policy are discussed.

Assessing demand-side barriers to uptake of intermittent preventive treatment for malaria in pregnancy: a qualitative study in two regions of Uganda.

To prevent malaria infection during pregnancy in endemic areas in Africa, the World Health Organization recommends the administration of intermittent preventive treatment in pregnancy (IPTp) as part of the focused antenatal care package. However, IPTp uptake in most countries remains low despite generally high antenatal care coverage and increased efforts by governments to address known bottlenecks such as drug stock-outs. The study explored factors that continue to impede uptake of IPTp among women who attend antenatal care. This paper focuses on demand-side barriers with regard to accessibility, affordability and acceptability. The research was conducted in 2013/2014 and involved 46 in-depth interviews with four types of respondents: (i) seven district health officials; (ii) 15 health workers; (iii) 19 women who attended antenatal care; (iv) five opinion leaders. Interviews were conducted in Eastern and West Nile regions of Uganda. Data was analysed by thematic analysis. District health officials and health workers cited a range of barriers relating to knowledge and attitudes among pregnant women, including lack of awareness of pregnancy-related health risks, a tendency to initiate antenatal care late, reluctance to take medication and concerns about side effects of IPTp. However, women and opinion leaders expressed very positive views of antenatal care and IPTp. They also reported that the burden of travel and cost associated with antenatal care attendance was challenging, but did not keep them from accessing a service they perceived as beneficial. The role of trust in health workers' expertise was highlighted by all respondents and it was reported that women will typically accept IPTp if encouraged by a health worker. Given the positive views of antenatal care and IPTp, high antenatal care coverage and reported low refusal rates for IPTp, supply-side issues are likely to account for the majority of missed opportunities for the provision of IPTp when women attend antenatal care. However, to increase uptake of IPTp on the demand side, health workers should be encouraged to reassure eligible women that IPTp is safe.

No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects.

PubMed

Heller, Monika K; Chapman, Sarah C E; Horne, Rob

2017-04-01

Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect. In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects. We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect. Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r Correct Recall  = -.273), were less able to differentiate between listed and unlisted side effects (r Recognition Sensitivity  = -.256) and were more likely to attribute the unlisted headache symptom as a side effect (r side effect attribution  = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects. Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.

Our understanding of the risk factors and complications of atrial fibrillation (AF) is based mostly on studies that have evaluated AF in a binary fashion (present or absent) and have not investigated AF burden. This scientific statement discusses the published literature and knowledge gaps related to methods of defining and measuring AF burden, the relationship of AF burden to cardiovascular and neurological outcomes, and the effect of lifestyle and risk factor modification on AF burden. Many studies examine outcomes by AF burden classified by AF type (paroxysmal versus nonparoxysmal); however, quantitatively, AF burden can be defined by longest duration, number of AF episodes during a monitoring period, and the proportion of time an individual is in AF during a monitoring period (expressed as a percentage). Current guidelines make identical recommendations for anticoagulation regardless of AF pattern or burden; however, a review of recent evidence suggests that higher AF burden is associated with higher risk of stroke. It is unclear whether the risk increases continuously or whether a threshold exists; if a threshold exists, it has not been defined. Higher burden of AF is also associated with higher prevalence and incidence of heart failure and higher risk of mortality, but not necessarily lower quality of life. A structured and comprehensive risk factor management program targeting risk factors, weight loss, and maintenance of a healthy weight appears to be effective in reducing AF burden. Despite this growing understanding of AF burden, research is needed into validation of definitions and measures of AF burden, determination of the threshold of AF burden that results in an increased risk of stroke that warrants anticoagulation, and discovery of the mechanisms underlying the weak temporal correlations of AF and stroke. Moreover, developments in monitoring technologies will likely change the landscape of long-term AF monitoring and could allow better definition of the significance of changes in AF burden over time. © 2018 American Heart Association, Inc.

Response to immune checkpoint therapy can be associated with a high mutation burden, but other mechanisms are also likely to be important. We identified a patient with metastatic gastric cancer with meaningful clinical benefit from treatment with the anti-programmed death-ligand 1 (PD-L1) antibody avelumab. This tumor showed no evidence of high mutation burden or mismatch repair defect but was strongly positive for presence of Epstein-Barr virus (EBV) encoded RNA. Analysis of The Cancer Genome Atlas gastric cancer data (25 EBV+, 80 microsatellite-instable [MSI], 310 microsatellite-stable [MSS]) showed that EBV-positive tumors were MSS. Two-sided Wilcoxon rank-sum tests showed that: 1) EBV-positive tumors had low mutation burden (median = 2.07 vs 3.13 in log10 scale, P < 10-12) but stronger evidence of immune infiltration (median ImmuneScore 2212 vs 1295, P < 10-4; log2 fold-change of CD8A = 1.85, P < 10-6) compared with MSI tumors, and 2) EBV-positive tumors had higher expression of immune checkpoint pathway (PD-1, CTLA-4 pathway) genes in RNA-seq data (log2 fold-changes: PD-1 = 1.85, PD-L1 = 1.93, PD-L2 = 1.50, CTLA-4 = 1.31, CD80 = 0.89, CD86 = 1.31, P < 10-4 each), and higher lymphocytic infiltration by histology (median tumor-infiltrating lymphocyte score = 3 vs 2, P < .001) compared with MSS tumors. These data suggest that EBV-positive low-mutation burden gastric cancers are a subset of MSS gastric cancers that may respond to immune checkpoint therapy.

Conservative, non-antibiotic and non-surgical management of acute diverticulitis is currently being investigated. To better inform clinical decisions, better understanding of disease mechanisms, disease burden and severity is needed. Literature search of risk factors, pathophysiology, epidemiology and disease burden/severity reported over the last decade. Acute diverticulitis is a common disease and has a high disease burden. Incidence of hospital admissions is reported around 71 per 100,000 population, with reported increase in several subpopulations over the last decades. The incidence is likely to increase further with the aging populations. Risk factors for left-sided acute diverticulitis include dietary, anthropometric and lifestyle factors. Disease mechanisms are still poorly understood, but a distinction between inflammation and infection is emerging. The integrative and complex role of the gut microbiota has become an interesting factor for both understanding the disease as well as a potential target for intervention using probiotics. Mild, self-limiting events are increasingly reported from studies of successful non-antibiotic management in a considerable number of cases. Risk markers of progression to or presence of severe, complicated disease are needed for better disease stratification. Current risk stratification by clinical, imaging or endoscopic means is imperfect and needs validation. Long-term results from minimal-invasive and comparative surgical trials may better help inform clinicians and patients. Over- and under-treatment as well as over- and under-diagnosis of severity is likely to continue in clinical practice due to lack of reliable, robust and universal severity and classification systems. Better understanding of pathophysiology is needed.

Background This article describes the personal, societal, and economic burden attributable to schizophrenia in the People’s Republic of China and highlights the potential for effective outpatient treatment to reduce this burden given recent changes in the Chinese health care system. The importance of effective antipsychotic therapy in reducing the burden of schizophrenia is also examined. Methods Published research on the burden, disability, management, and economic costs of schizophrenia in the People’s Republic of China was examined in the context of the larger body of global research. Research written in English or Chinese and published before June 2012 was identified using PubMed, CNKI, and Wanfang Med database searches. The contribution of effective antipsychotic therapy in reducing the risk for relapse and hospitalization and improving patients’ functioning is described. Results Schizophrenia imposes a substantial burden on Chinese society, with indirect costs accounting for the majority of the total cost. Functional impairment is high, leading to lost wages and work impairment. In the People’s Republic of China, schizophrenia is the most common diagnosis among hospitalized psychiatric patients. Ongoing changes in the Chinese health care system may reduce some barriers to effective relapse prevention in schizophrenia and potentially reduce hospitalizations. The use of antipsychotics for acute episodes and maintenance treatment has been shown to decrease symptom severity and reduce the risk for relapse and hospitalization. However, discontinuing antipsychotic medication appears common and is a strong predictor of relapse. Cost-effectiveness research in the People’s Republic of China is needed to examine the potential gains from improved outpatient antipsychotic treatment. Conclusion Schizophrenia is a very costly mental illness in terms of personal, economic, and societal burden, both in the People’s Republic of China and globally. When treated effectively, patients tend to persist longer with antipsychotic treatment, have fewer costly relapses, and have improved functioning. Further research examining the long-term effects of reducing barriers to effective treatments on the societal burden of schizophrenia in the People’s Republic of China is needed. PMID:23983478

A better understanding of potential relationship between mood disorders, sleep quality, pain, and headache frequency may assist clinicians in determining optimal therapeutic programs. The aim of the current study was to analyze the effects of sleep quality, anxiety, depression on potential relationships between headache intensity, burden of headache, and headache frequency in chronic tension type headache (CTTH). One hundred and ninety-three individuals with CTTH participated. Headache features were collected with a 4-weeks headache diary. The Hospital Anxiety and Depression Scale was used for assessing anxiety and depression. Headache Disability Inventory evaluated the burden of headache. Pain interference was determined with the bodily pain domain (SF-36 questionnaire). Sleep quality was assessed with Pittsburgh Sleep Quality Index. Path analyses with maximum likelihood estimations were conducted to determine the direct and indirect effects of depression, anxiety, and sleep quality on the frequency of headaches. Two paths were observed: the first with depression and the second with sleep quality as mediators. Direct effects were noted from sleep quality, emotional burden of disease and pain interference on depression, and from depression to headache frequency. The first path showed indirect effects of depression from emotional burden and from sleep quality to headache frequency (first model R 2  = 0.12). Direct effects from the second path were from depression and pain interference on sleep quality and from sleep quality on headache frequency. Sleep quality indirectly mediated the effects of depression, emotional burden and pain interference on headache frequency (second model R 2  = 0.18). Depression and sleep quality, but not anxiety, mediated the relationship between headache frequency and the emotional burden of disease and pain interference in CTTH.

The reform of the system in 2006 aimed at reducing waiting lists in an efficient manner. Performance-linked funding and regulated competition did indeed lead to improved efficiency. The other side of the coin is overtreatment, and expensive and not infrequently damaging growth in volume. In order to control costs, three strategies have been determined: agreements with an annual cap on volume; (b) collaboration of regional health-care providers with the mission of improving results in health care (with profit-sharing if costs fall); and (c) fusions reducing the number of hospitals which reduces the burden of injuries (supply no longer creates its own demand). This article comments on these strategies. The author argues for a fourth approach: if the quality of health care improves, the number of complications will fall, overtreatment will decline and the outcome will be a decrease in burden of injuries. This requires the health care insurers to modify the way they manage their contracts and methods of payment, and stimulates competition based on quality.

Effects of user fee exemptions on the provision and use of maternal health services: a review of literature.

User fee removal has been put forward as an approach to increasing priority health service utilization, reducing impoverishment, and ultimately reducing maternal and neonatal mortality. However, user fees are a source of facility revenue in many low-income countries, often used for purchasing drugs and supplies and paying incentives to health workers. This paper reviews evidence on the effects of user fee exemptions on maternal health service utilization, service provision, and outcomes, including both supply-side and demand-side effects. We reviewed 19 peer-reviewed research articles addressing user fee exemptions and maternal health services or outcomes published since 1990. Studies were identified through a USAID-commissioned call for evidence, key word search, and screening process. Teams of reviewers assigned criteria-based quality scores to each paper and prepared structured narrative reviews. The grade of the evidence was found to be relatively weak, mainly from short-term, non-controlled studies. The introduction of user fee exemptions appears to have resulted in increased rates of facility-based deliveries and caesarean sections in some contexts. Impacts on maternal and neonatal mortality have not been conclusively demonstrated; exemptions for delivery care may contribute to modest reductions in institutional maternal mortality but the evidence is very weak. User fee exemptions were found to have negative, neutral, or inconclusive effects on availability of inputs, provider motivation, and quality of services. The extent to which user fee revenue lost by facilities is replaced can directly affect service provision and may have unintended consequences for provider motivation. Few studies have looked at the equity effects of fee removal, despite clear evidence that fees disproportionately burden the poor. This review highlights potential and documented benefits (increased use of maternity services) as well as risks (decreased provider motivation and quality) of user fee exemption policies for maternal health services. Governments should link user fee exemption policies with the replacement of lost revenue for facilities as well as broader health system improvements, including facility upgrades, ensured supply of needed inputs, and improved human resources for health. Removing user fees may increase uptake but will not reduce mortality proportionally if the quality of facility-based care is poor. More rigorous evaluations of both demand- and supply-side effects of mature fee exemption programmes are needed.

To analyse the relationship between satisfaction with leisure time and subjective burden, depression and anxiety in caregivers of dependent elderly relatives. Cross-sectional study. Primary health care (Andalusia, Spain). A probabilistic sample of 200 primary caregivers of dependent elderly relatives. Satisfaction with leisure time, subjective burden, anxiety, depression, and objective burden (functional ability, cognitive impairment and behavioural problems of the care recipient, and dedication to caring of the caregiver). Most of the caregivers were women, daughters of the care recipients, and shared home with them. An inverse statistical association was found between satisfaction with leisure time and subjective burden (r=-0.55, 95%CI: -0.45 to -0.64), anxiety (r=-0.30, 95%CI: -0.17 to -0.41) and depression (r=-0.25, 95%CI: -0.11 to -0.37). These associations remained after controlling for objective burden. Satisfaction with leisure time may have a protective effect on subjective burden, anxiety and depression, regardless of objective burden. Copyright © 2015 Elsevier España, S.L.U.

We describe the coupling of the Goddard Institute for Space Studies (GISS) general circulation model (GCM) to an online sulfur chemistry model and source models for organic matter and sea-salt that is used to estimate the aerosol indirect effect. The cloud droplet number concentration is diagnosed empirically from field experiment datasets over land and ocean that observe droplet number and all three aerosol types simultaneously; corrections are made for implied variations in cloud turbulence levels. The resulting cloud droplet number is used to calculate variations in droplet effective radius, which in turn allows us to predict aerosol effects on cloud optical thickness and microphysical process rates. We calculate the aerosol indirect effect by differencing the top-of-the-atmosphere net cloud radiative forcing for simulations with present-day vs. pre-industrial emissions. Both the first (radiative) and second (microphysical) indirect effects are explored. We test the sensitivity of our results to cloud parameterization assumptions that control the vertical distribution of cloud occurrence, the autoconversion rate, and the aerosol scavenging rate, each of which feeds back significantly on the model aerosol burden. The global mean aerosol indirect effect for all three aerosol types ranges from -1.55 to -4.36 W m(exp -2) in our simulations. The results are quite sensitive to the pre-industrial background aerosol burden, with low pre-industrial burdens giving strong indirect effects, and to a lesser extent to the anthropogenic aerosol burden, with large burdens giving somewhat larger indirect effects. Because of this dependence on the background aerosol, model diagnostics such as albedo-particle size correlations and column cloud susceptibility, for which satellite validation products are available, are not good predictors of the resulting indirect effect.

Housing Affordability And Children's Cognitive Achievement.

PubMed

Newman, Sandra; Holupka, C Scott

2016-11-01

Housing cost burden-the fraction of income spent on housing-is the most prevalent housing problem affecting the healthy development of millions of low- and moderate-income children. By affecting disposable income, a high burden affects parents' expenditures on both necessities for and enrichment of their children, as well as investments in their children. Reducing those expenditures and investments, in turn, can affect children's development, including their cognitive skills and physical, social, and emotional health. This article summarizes the first empirical evidence of the effects of housing affordability on children's cognitive achievement and on one factor that appears to contribute to these effects: the larger expenditures on child enrichment by families in affordable housing. We found that housing cost burden has the same relationship to both children's cognitive achievement and enrichment spending on children, exhibiting an inverted U shape in both cases. The maximum benefit occurs when housing cost burden is near 30 percent of income-the long-standing rule-of-thumb definition of affordable housing. The effect of the burden is stronger on children's math ability than on their reading comprehension and is more pronounced with burdens above the 30 percent standard. For enrichment spending, the curve is "shallower" (meaning the effect of optimal affordability is less pronounced) but still significant. Project HOPE—The People-to-People Health Foundation, Inc.

Background: Living with heart failure patients is a complex situation for family caregivers. Few studies have been conducted to examine the effects of interventional programs to ease this condition. The purpose of this study was to determine the effectiveness of a supportive educative group intervention in reducing family caregivers’ burden of caregiving. Materials and Methods: This randomized clinical trail was conducted at a selective teaching hospital in Isfahan, Iran in 2012. The intervention consisted of four weekly multimedia training sessions of 2 h that included education and family support for 50 family caregivers. Caregiver burden was measured using the Zarit Burden Interview (ZBI). Paired t-test, Student's t-tests, and repeated measures analysis of variance (ANOVA) were used to test for significant differences of the mean scores of burden between the intervention and control groups over a 3-month period. Results: The intervention was successful in reducing caregiver burden over time both at the end of the intervention period (P = 0.000) and 3 months after the intervention (P = 0.000). Conclusions: Nurses and other healthcare providers can use the findings of this study in order to implement effective programs to reduce family caregivers’ challenges and to provide them more support.

Background Opioids are widely accepted as treatment for moderate to severe pain, and opioid-induced constipation is one of the most common side effects of opioids. This side effect negatively affects pain management and patients’ quality of life, which could result in increased healthcare utilization and costs. Objective To assess healthcare utilization and costs (all-cause, constipation-related, and pain-related) for individuals with and without opioid-induced constipation during the 12 months after initiation of opioid therapy for noncancer pain. Methods This retrospective cohort study was conducted using administrative claims data from HealthCore Integrated Research Environment between January 1, 2006, and June 30, 2014. The analysis was limited to patients aged ≥18 years who filled a prescription for continuous opioid treatment (≥28 days) for noncancer pain. Propensity scores were used to match opioid users with constipation (cohort 1) and opioid users without constipation (cohort 2), using a 1:1 ratio. Generalized linear models were used to estimate all-cause, constipation-related, and pain-related healthcare utilization and costs during the 12 months after the initiation of opioid therapy. Results After matching and balancing for all prespecified variables, 17,384 patients were retained in each cohort (mean age, 56 years; 63% female). Opioid users with constipation were twice as likely as those without constipation to have ≥1 inpatient hospitalizations (odds ratio, 2.28; 95% confidence interval [CI], 2.17–2.39) during the 12 months. The total mean adjusted overall costs per patient during the study period were $12,413 higher for patients with constipation versus those without it (95% CI, $11,726–$13,116). The total mean adjusted overall pain-related costs per patient were $6778 (95% CI, $6293–$7279) higher for the patients with constipation than those without. Among patients using opioids for noncancer pain, the annual mean constipation-related costs per patient totaled $4646 (total average plan-paid costs, $4424; total patient-paid costs, $222). Conclusions Patients using opioids with newly diagnosed constipation had significantly greater healthcare utilization and costs than patients without constipation; these costs accounted for approximately 16% of the total healthcare costs per patient during the 12-month study period. Recognition and effective treatment of opioid-induced constipation may decrease healthcare utilization for patients with chronic noncancer pain and may reduce the economic burden of pain therapy.

In this study, we sought to 1) describe elements of the financial and quality-of-life burden of dysfunctional uterine bleeding (DUB) from the perspective of women who agreed to obtain surgical treatment; 2) explore associations between DUB symptom characteristics and the financial and quality-of-life burden; 3) estimate the annual dollar value of the financial burden; and 4) estimate the most that could be spent on surgery to eliminate DUB symptoms for which medical treatment has been unsuccessful that would result in a $50,000/quality-adjusted life-year incremental cost-effectiveness ratio. We collected baseline data on DUB symptoms and aspects of the financial and quality-of-life burden for 237 women agreeing to surgery for DUB in a randomized trial comparing hysterectomy with endometrial ablation. Measures included out-of-pocket pharmaceutical expenditures, excess expenditures on pads or tampons, the value of time missed from paid work and home management activities, and health utility. We used chi2 and t tests to assess the statistical significance of associations between DUB characteristics and the financial and quality-of-life burden. The annual financial burden was estimated. Pelvic pain and cramps were associated with activity limitations and tiredness was associated with a lower health utility. Excess pharmaceutical and pad and tampon costs were $333 per patient per year (95% confidence interval [CI], $263-$403). Excess paid work and home management loss costs were $2,291 per patient per year (95% CI, $1847-$2752). Effective surgical treatment costing $40,000 would be cost-effective compared with unsuccessful medical treatment. The financial and quality-of-life effects of DUB represent a substantial burden.

A unified frame of predicting side effects of drugs by using linear neighborhood similarity.

Drug side effects are one of main concerns in the drug discovery, which gains wide attentions. Investigating drug side effects is of great importance, and the computational prediction can help to guide wet experiments. As far as we known, a great number of computational methods have been proposed for the side effect predictions. The assumption that similar drugs may induce same side effects is usually employed for modeling, and how to calculate the drug-drug similarity is critical in the side effect predictions. In this paper, we present a novel measure of drug-drug similarity named "linear neighborhood similarity", which is calculated in a drug feature space by exploring linear neighborhood relationship. Then, we transfer the similarity from the feature space into the side effect space, and predict drug side effects by propagating known side effect information through a similarity-based graph. Under a unified frame based on the linear neighborhood similarity, we propose method "LNSM" and its extension "LNSM-SMI" to predict side effects of new drugs, and propose the method "LNSM-MSE" to predict unobserved side effect of approved drugs. We evaluate the performances of LNSM and LNSM-SMI in predicting side effects of new drugs, and evaluate the performances of LNSM-MSE in predicting missing side effects of approved drugs. The results demonstrate that the linear neighborhood similarity can improve the performances of side effect prediction, and the linear neighborhood similarity-based methods can outperform existing side effect prediction methods. More importantly, the proposed methods can predict side effects of new drugs as well as unobserved side effects of approved drugs under a unified frame.

2011-01-01

Objective To extract physician-asserted drug side effects from electronic medical record clinical narratives. Materials and methods Pattern matching rules were manually developed through examining keywords and expression patterns of side effects to discover an individual side effect and causative drug relationship. A combination of machine learning (C4.5) using side effect keyword features and pattern matching rules was used to extract sentences that contain side effect and causative drug pairs, enabling the system to discover most side effect occurrences. Our system was implemented as a module within the clinical Text Analysis and Knowledge Extraction System. Results The system was tested in the domain of psychiatry and psychology. The rule-based system extracting side effects and causative drugs produced an F score of 0.80 (0.55 excluding allergy section). The hybrid system identifying side effect sentences had an F score of 0.75 (0.56 excluding allergy section) but covered more side effect and causative drug pairs than individual side effect extraction. Discussion The rule-based system was able to identify most side effects expressed by clear indication words. More sophisticated semantic processing is required to handle complex side effect descriptions in the narrative. We demonstrated that our system can be trained to identify sentences with complex side effect descriptions that can be submitted to a human expert for further abstraction. Conclusion Our system was able to extract most physician-asserted drug side effects. It can be used in either an automated mode for side effect extraction or semi-automated mode to identify side effect sentences that can significantly simplify abstraction by a human expert.

What matters when judging intentionality-moral content or normative status? Testing the rational scientist model of the side-effect.

PubMed

Papadopoulos, C; Hayes, B K

2018-06-01

Previous work has demonstrated a "side-effect effect," such that intentionality is more likely to be attributed to agents who bring about negatively valenced as opposed to positively valenced side effects. The rational-scientist model explains this by suggesting that norm-violating side effects are more informative for inferring intentionality than norm-conforming side effects. In the present study we reexamined this account, addressing limitations of previous empirical tests (e.g., Uttich & Lombrozo, Cognition 116: 87-100, 2010). Side-effect valence and norm status were manipulated factorially, enabling an examination of the impact of norm status on intentionality judgments in both positively and negatively valenced side effects. Additionally, the impact of side-effect norm status on the perceived valences of side effects and agents was examined. Effects of norm status were found for both positive and negative side effects. Violation of an ostensibly neutral norm led to negative perceptions of the side effect. However, a norm status effect on intentionality judgments persisted when these effects were controlled. These results support the view that the side-effect effect is the result of the rational use of social-cognitive evidence.

Latinos comprise a growing segment of the caregiver population and vary widely in acculturation, yet little is known regarding how acculturation might affect caregiver stress or intervention outcomes. This study examined the relationship between acculturation and burden, bother, and depression in Latino dementia caregivers at baseline and following an intervention. This was a secondary data analysis of 211 Latino caregivers of older adults with dementia from Resources for Enhancing Alzheimer's Caregiver Health (REACH) II, a multisite randomized trial of caregiver interventions. Baseline and follow-up data were used to run mixed-effects models examining the main and moderating effect of acculturation on caregiver stress. No significant main effect of acculturation was found for any of the outcome measures, controlling for demographic covariates. Acculturation moderated the effect of the intervention on caregiver burden: those who were more acculturated benefited more from the intervention. Differential acculturation for Latino caregivers was not directly associated with caregiver burden, bother, or depression, but was associated with reducing burden from the intervention. Future research should explore by what mechanism acculturation influences caregiver burden following an intervention.

To compare a 2 day bowel preparation regime of barium, iodine and a mild stimulant laxative with a 1 day iodine-only regime for CT colonography (CTC). 100 consecutive patients underwent CTC. The first 50 patients (Regime 1) ingested 1 bisacodyl tablet twice a day 3 days before CTC and 1 dose each of 50 ml of barium and 20 ml of iodinated contrast per day starting 2 days before CTC. The second 50 patients (Regime 2) ingested 3 doses of iodinated contrast over 24 h prior to CTC. Volumes of residual stool and fluid, and the effectiveness of stool and fluid tagging, were graded according to methods established by Taylor et al (Taylor S, Slaker A, Burling D, Tam E, Greenhalgh R, Gartner L, et al. CT colonography: optimisation, diagnostic performance and patient acceptability of reduced-laxative regimens using barium-based faecal tagging. Eur Radiol 2008; 18: 32-42). A 3 day low-residue diet was taken by both cohorts. Questionnaires rating the side-effects and burden of the bowel preparation were compared to a control cohort of patients undergoing barium enema. The proportion of colons producing none/scattered stool (score 1) was 90.3% with Regime 1 and 65.0% with Regime 2 (p<0.005). Any residual stool was significantly better tagged with Regime 1 (score 5), with 91.7% of Regime 1 exhibiting optimum tagging vs 71.3% of Regime 2 (p<0.05). No significant differences in side-effects between the bowel preparation regimes for CTC were elicited. Bowel preparation for barium enema was tolerated significantly worse than both of the CTC bowel preparation regimes. Regime 1, containing a 3 day preparation of a mild laxative, barium and iodine, produced a significantly better prepared colon, with no difference in patient acceptability.

Key issues that must be considered before a new contraceptive is introduced center on the need for a trained provider to begin or terminate the method, its side effects, duration of use, method's ability to meet users' needs and preferences, and extra training or staff requirements. Logistics and economic issues to consider are identifying a dependable way of effectively supplying commodities, planning extra services needed for the method, and cost of providing the method. Each contraceptive method presents a different side effect pattern and burdens the service delivery setting differently. The strategy developed to introduce or expand the 3-month injectable Depo-Provera (DMPA) can be used for any method. It includes a needs assessment and addresses regulatory issues, service delivery policies and procedures, information and training, evaluation, and other concerns. Viet Nam's needs assessment showed that Norplant should not be introduced until the service delivery system becomes stronger. Any needs assessment for expansion of contraceptive services should cover sexually transmitted disease/HIV issues. A World Health Organization strategy helps officials identify the best method mix for local situations. Introductory strategies must aim to improve the quality of family planning programs and expand choices. Many begin by examining existing data and conducting interviews with policymakers, users, providers, and women's health advocates. Introductory programs for Norplant focus on provider training, adequate counseling and informed consent for users, and ready access to removal. They need a well-prepared service delivery infrastructure. The first phase of the DMPA introductory strategy for the Philippines comprised a social marketing campaign and DMPA introduction at public clinics in 10 pilot areas with strong service delivery. Successful AIDS prevention programs show that people tend to use barrier methods when they are available. USAID is currently studying whether or not women in developing countries will use the female condom.

Cooking over open fires using solid fuels is both common practice throughout much of the world and widely recognized to contribute to human health, environmental, and social problems. The public health burden of household air pollution includes an estimated four million premature deaths each year. To be effective and generate useful insight into potential solutions, cookstove intervention studies must select cooking technologies that are appropriate for local socioeconomic conditions and cooking culture, and include interdisciplinary measurement strategies along a continuum of outcomes. REACCTING (Research on Emissions, Air quality, Climate, and Cooking Technologies in Northern Ghana) is an ongoing interdisciplinary randomized cookstove intervention study in the Kassena-Nankana District of Northern Ghana. The study tests two types of biomass burning stoves that have the potential to meet local cooking needs and represent different "rungs" in the cookstove technology ladder: a locally-made low-tech rocket stove and the imported, highly efficient Philips gasifier stove. Intervention households were randomized into four different groups, three of which received different combinations of two improved stoves, while the fourth group serves as a control for the duration of the study. Diverse measurements assess different points along the causal chain linking the intervention to final outcomes of interest. We assess stove use and cooking behavior, cooking emissions, household air pollution and personal exposure, health burden, and local to regional air quality. Integrated analysis and modeling will tackle a range of interdisciplinary science questions, including examining ambient exposures among the regional population, assessing how those exposures might change with different technologies and behaviors, and estimating the comparative impact of local behavior and technological changes versus regional climate variability and change on local air quality and health outcomes. REACCTING is well-poised to generate useful data on the impact of a cookstove intervention on a wide range of outcomes. By comparing different technologies side by side and employing an interdisciplinary approach to study this issue from multiple perspectives, this study may help to inform future efforts to improve health and quality of life for populations currently relying on open fires for their cooking needs.

Aim Chemotherapy side effects are often reported in clinical trials; however, there is little evidence about their incidence in routine clinical care. The objective of this study was to describe the frequency and severity of patient-reported chemotherapy side effects in routine care across treatment centres in Australia. Methods We conducted a prospective cohort study of individuals with breast, lung or colorectal cancer undergoing chemotherapy. Side effects were identified by patient self-report. The frequency, prevalence and incidence rates of side effects were calculated by cancer type and grade, and cumulative incidence curves for each side effect computed. Frequencies of side effects were compared between demographic subgroups using chi-squared statistics. Results Side effect data were available for 449 eligible individuals, who had a median follow-up of 5.64 months. 86% of participants reported at least one side effect during the study period and 27% reported a grade IV side effect, most commonly fatigue or dyspnoea. Fatigue was the most common side effect overall (85%), followed by diarrhoea (74%) and constipation (74%). Prevalence and incidence rates were similar across side effects and cancer types. Age was the only demographic factor associated with the incidence of side effects, with older people less likely to report side effects. Conclusion This research has produced the first Australian estimates of self-reported incidence of chemotherapy side effects in routine clinical care. Chemotherapy side effects in routine care are common, continue throughout chemotherapy and can be serious. This work confirms the importance of observational data in providing clinical practice-relevant information to decision-makers. PMID:29016607

Treatments based on antimonials to cutaneous leishmaniasis (CL) entail a range of toxic side effects. Propolis, a natural compound widely used in traditional medical applications, exhibits a range of biological effects, including activity against infectious agents. The aim of this study was to test the potential leishmanicidal effects of different propolis extracts against Leishmania (Viannia) braziliensis promastigotes and intracellular amastigotes in vitro. Stationary-phase L. (V) braziliensis promastigotes were incubated with medium alone or treated with dry, alcoholic, or glycolic propolis extract (10, 50, or 100 μg/mL) for 96 h. Our data showed that all extracts exhibited a dose-dependent effect on the viability of L. (V) braziliensis promastigotes, while controlling the parasite burden inside infected macrophages. Dry propolis extract significantly modified the inflammatory profile of murine macrophages by downmodulating TGF-β and IL-10 production, while upmodulating TNF-α. All three types of propolis extract were found to reduce nitric oxide and superoxide levels in activated L. braziliensis-infected macrophages. Altogether, our results showed that propolis extracts exhibited a leishmanicidal effect against both stages of L. (V) braziliensis. The low cell toxicity and efficient microbicidal effect of alcoholic or glycolic propolis extracts make them candidates to an additive treatment for cutaneous leishmaniasis. PMID:28690662

Background The side effects and burden of anticoagulant treatments may contribute to poor compliance and consequently to treatment failure. A specific questionnaire is necessary to assess patients' needs and their perceptions of anticoagulant treatment. Methods A conceptual model of expectation and satisfaction with anticoagulant treatment was designed by an advisory board and used to guide patient (n = 31) and clinician (n = 17) interviews in French, US English and Dutch. Patients had either atrial fibrillation (AF), deep venous thrombosis (DVT), or pulmonary embolism (PE). Following interviews, three PACT-Q language versions were developed simultaneously and further pilot-tested by 19 patients. Linguistic validations were performed for additional language versions. Results Initial concepts were developed to cover three areas of interest: 'Treatment', 'Disease and Complications' and 'Information about disease and anticoagulant treatment'. After clinician and patient interviews, concepts were further refined into four domains and 17 concepts; test versions of the PACT-Q were then created simultaneously in three languages, each containing 27 items grouped into four domains: "Treatment Expectations" (7 items), "Convenience" (11 items), "Burden of Disease and Treatment" (2 items) and "Anticoagulant Treatment Satisfaction" (7 items). No item was deleted or added after pilot testing as patients found the PACT-Q easy to understand and appropriate in length in all languages. The PACT-Q was divided into two parts: the first part to measure the expectations and the second to measure the convenience, burden and treatment satisfaction, for evaluation prior to and after anticoagulant treatment, respectively. Eleven additional language versions were linguistically validated. Conclusion The PACT-Q has been rigorously developed and linguistically validated. It is available in 14 languages for use with thromboembolic patients, including AF, PE and DVT patients. Its validation and psychometric properties have been tested and are presented in a separate manuscript. PMID:19196486

Patients with cervical dystonia (CD) receive much of their care at university based hospital outpatient clinics. This study aimed to describe the clinical characteristics and treatment experiences of patients who continued care at our university based movement disorders clinic, and to document the reasons for which a subset discontinued care. Seventy patients (77% female) were recruited from all patients at the clinic (n = 323). Most (93%) were treated with botulinum neurotoxin (BoNT) injection, and onabotulinumtoxinA was initially used in 97%. The average dose of onabotulinumtoxinA was 270.4 U (range 50–500) and the median number of injections was 14 (range: 1–39). Twenty one patients later received at least one cycle of rimabotulinumtoxinB (33%); of those, 10 switched back to onabotulinumtoxinA (48%). The initial rimabotulinumtoxinB dose averaged 11,996 units (range: 3000–25,000 over 1–18 injections). Twenty one patients (30%) discontinued care. Reasons cited included suboptimal response to BoNT therapy (62%), excessive cost (24%), excessive travel burden (10%), and side effects of BoNT therapy (10%). Most patients (76%) did not seek further care after leaving the clinic. Patients who terminated care received fewer treatment cycles (5.5 vs. 13.0, p = 0.020). There were no other identifiable differences between groups in gender, age, disease characteristics, toxin dose, or toxin formulation. These results indicate that a significant number of CD patients discontinue care due to addressable barriers to access, including cost and travel burden, and that when leaving specialty care, patients often discontinue treatment altogether. These data highlight the need for new initiatives to reduce out-of-pocket costs, as well as training for community physicians on neurotoxin injection in order to lessen the travel burden patients must accept in order to receive standard-of-care treatments.

Care burden of parents of adult children with mental illness: The role of associative stigma.

PubMed

Park, Keunwoo; Seo, Mikyung

2016-10-01

Parents of offspring with mental illness must endure endless child care burden despite their old age, and must cope with associative stigma. This study analyzed the mediator effect of associative stigma on relationships between the main stressors, psychiatric symptoms and lowered social function of offspring with mental illness, assessed by the parents, and their care burden. 215 parents caring for an adult child with mental illness in Korea were surveyed (Mage=60.68, SD=13.58; 74.4% mothers). They were asked to assess the psychiatric symptoms and social function of their offspring, the stigma they experienced, and the objective/subjective care burdens they felt. Our findings suggest that the symptoms and function of offspring directly affect the care burden of parents, but also have an indirect effect mediated by associative stigma. Among the predictor variables, symptoms have a greater effect on the subjective/objective burden and associative stigma than social function. We suggest strategies for parents to overcome associative stigma and emphasize the professional endeavor required to meet the service needs of elderly parents taking care of an adult child with mental illness.

Adverse complications associated with systemic administration of anti-cancer drugs are a major problem in cancer therapy in current clinical practice. To increase effectiveness and reduce side effects, localized drug delivery to tumour sites requiring therapy is essential. Direct delivery of potent anti-cancer drugs locally to the cancer site based on nanotechnology has been recognised as a promising alternative approach. Previously, we reported the design and fabrication of nano-engineered 3D titanium wire based implants with titania (TiO2) nanotube arrays (Ti-TNTs) for applications such as bone integration by using in-vitro culture systems. The aim of present study is to demonstrate the feasibility of using such Ti-TNTs loaded with anti-cancer agent for localized cancer therapy using pre-clinical cancer models and to test local drug delivery efficiency and anti-tumour efficacy within the tumour environment. TNF-related apoptosis-inducing ligand (TRAIL) which has proven anti-cancer properties was selected as the model drug for therapeutic delivery by Ti-TNTs. Our in-vitro 2D and 3D cell culture studies demonstrated a significant decrease in breast cancer cell viability upon incubation with TRAIL loaded Ti-TNT implants (TRAIL-TNTs). Subcutaneous tumour xenografts were established to test TRAIL-TNTs implant performance in the tumour environment by monitoring the changes in tumour burden over a selected time course. TRAIL-TNTs showed a significant regression in tumour burden within the first three days of implant insertion at the tumour site. Based on current experimental findings these Ti-TNTs wire implants have shown promising capacity to load and deliver anti-cancer agents maintaining their efficacy for cancer treatment.

Pain remains a problem for people with cancer despite effective treatments being available. We aimed to explore current pain management strategies used by patients, caregivers and professionals and to investigate opportunities for digital technologies to enhance cancer pain management. A qualitative study comprising semistructured interviews and focus groups. Patients with cancer pain, their caregivers and health professionals from Northeast Scotland were recruited from a purposive sample of general practices. Professionals were recruited from regional networks. Fifty one participants took part in 33 interviews (eight patients alone, six patient/caregiver dyads and 19 professionals) and two focus groups (12 professionals). Living with cancer was hard work for patients and caregivers and comparable to a 'full-time job'. Patients had personal goals which involved controlling pain intensity and balancing this with analgesic use, side effects, overall symptom burden and social/physical activities.Digital technologies were embraced by most patients, and made living life with advanced cancer easier and richer (eg, video calls with family). Technology was underutilised for pain and symptom management. There were suggestions that technology could support self-monitoring and communicating problems to professionals, but patients and professionals were concerned about technological monitoring adding to the work of managing illness. Cancer pain management takes place in the context of multiple, sometimes competing personal goals. It is possible that technology could be used to help patients share individual symptom experiences and goals, thus enhancing tailored care. The challenge is for digital solutions to add value without adding undue burden. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2013-01-01

Dietary supplementation has become progressively more prevalent, with over half of the American population reporting use of various products. An increased incidence of supplement use has been reported in the military especially within Special Operations Forces (SOF) where training regimens rival those of elite athletes. Federal regulations regarding dietary supplements are minimal, allowing for general advertisement to the public without emphasis on the potentially harmful side effects. Subsequent medical care for these negative effects causes financial burden on the military in addition to the unit?s loss of an Operator and potential mission compromise. This report reviews a case of an Operator diagnosed with drug-induced liver injury secondary to a testosterone prohormone supplement called Post Cycle II. Clinical situations like this emphasize the necessity that SOF Operators and clinicians be aware of the risks and benefits of these minimally studied substances. Providers should also be aware of the Human Performance Resource Center for Health Information and Natural Medicines Comprehensive Database supplement safety ratings as well as the Food and Drug Administration?s MedWatch and Natural Medicines WATCH, to which adverse reactions should be reported. 2013.

Treatment of older patients with colorectal cancer: a perspective review

PubMed Central

Kordatou, Z.; Kountourakis, P.

2014-01-01

In a continuously aging population, the burden of colorectal cancer (CRC) is rising among older patients. Despite the fact that almost half of the cases occur in patients over 75 years, this age group is subjected to disparities regarding diagnostic and therapeutic options. So far, exclusion of older patients from randomized clinical trials has resulted in a lack of evidence-based guidelines. Nevertheless, newer data from studies specifically targeting older patients and subgroup analyses indicate that proper treatment planning and specific medical and geriatric assessment can achieve a safe and beneficial treatment result in older patients, often with similar outcomes to their younger counterparts. Resection of the primary tumour, if feasible, should be the primary goal of surgery aiming for cure, although it should be avoided under emergency conditions. Chronological age per se should not be an exclusion criterion for adjuvant or palliative chemotherapy, or targeted therapies. Careful patient selection, dose adjustments, close monitoring and early intervention in the event of side effects are essential. The benefits of treatment must be balanced with potential effects of treatment and patients’ wishes. PMID:24790652

Symptom-Based Controller Therapy: A New Paradigm for Asthma Management

PubMed Central

Divekar, Rohit; Ameredes, Bill T.; Calhoun, William J.

2013-01-01

Appropriate management of persistent asthma, according to US and international guidelines, requires daily use of controller medications, most generally, inhaled corticosteroids (ICS). This approach, although effective and well established, imposes burdens of treatment and side effects onto asthma patients. A growing body of evidence suggests that patients with persistent asthma need not be managed with daily ICS, but rather can use them on an intermittent basis, occasioned by the occurrence of symptoms sufficient to warrant treatment with a rescue inhaler. Large, randomized, controlled studies, over a range of asthma severity, and in a range of ages from pediatrics to adults, suggest that in well-selected patients, a symptom based approach to administering controller therapy may produce equivalent outcomes, while reducing exposure to ICS. The concept of providing anti-inflammatory treatment to the patient, at the time inflammation is developing, is termed ‘temporal personalization’. The evidence to date suggests that symptom-based controller therapy is broadly useful in selected asthma patients, and is a management approach that could be incorporated into US and international guidelines for asthma.

1998-04-01

Many side effects are associated with the use of anti-HIV drugs, impacting the development of drug resistance and the quality of life for HIV-patients. Concern about side effects is a primary factor in deterring people from beginning HIV therapy. Frequency and severity of side effects vary greatly, but they are frequently more common and severe in people who are taking a new drug or who have advanced HIV disease. Information on side effects comes largely from clinical trials; however, many side effects are not discovered until the drug has been approved and used by larger numbers of people. Side effects vary from serious toxicities that require stopping treatment to uncomfortable or annoying side effects that interfere with daily life. A table categorizes the four major side effects (nausea, fever, skin rash, and fatigue) and divides them into grades that describe their intensity. A chart lists the side effects associated with specific anti-HIV drugs. Suggestions for managing side effects are included.

Health care workers (HCW) in low and middle income countries are at high risk of nosocomial tuberculosis infection. Periodic screening of health workers for both TB disease and infection can play a critical role in TB infection control. Occupational health programs that implement serial tuberculin skin testing (TST) are advised to use a two-step baseline TST. This helps to ensure that boosting of waned immune response is not mistaken as new TB infection (i.e. conversion). However, there are no data on safety of the two-step TST in the Indian context where HCWs are repeatedly exposed. Nursing students were recruited from 2007 to 2009 at the Christian Medical College and Hospital, Vellore, India. Consenting nursing students were screened with a baseline two-step TST at the time of recruitment. From 2007 to 2008 adverse events were recorded when reported during the TST reading (Cohort A). Nurses recruited in the final study year (2009) answered an investigator administered questionnaire assessing all likely side-effects Cohort B). This information was extracted from the case report forms and analysed. Between 2007 and 09, 800 trainees consented to participate in the annual TB screening study and 779 did not have a past history of TB or recall a positive TST and were selected to administer TST. Of these, 755 returned for reading the result and had complete data and were included for the final analysis - 623 subjects in (cohort A) and 132 in (cohort B). These were included for the final analysis. In cohort A only 1.3% reported adverse events. In cohort B, as per the investigator administered questionnaire; 25% reported minor side effects. Itching and local pain were the most common side effects encountered. There were no major adverse events reported. In particular, the adverse events were similar in the second step of the test and not more severe. Screening of HCWs with two-step TST for LTBI is simple and safe, and hence suitable for wide scale implementation in high-burden settings such as India.

Treatment of hypertension is expensive and cost is one of the reasons for inadequate blood pressure control. Where there are no social cost cushions, the burden is borne by patients. With pervasive poverty and inadequate control, complications are unchecked. Back titration in appropriate circumstances should, therefore, translate to economic benefit. This is an attempt to compute, in economic terms, the benefit of back titration. Thirty-nine patients who entered an antihypertensive back titration program for 12 months and who had been earlier reported on, form the subject of this study. A survey of the cost of antihypertensives in pharmacy outlets in Jos, Nigeria was undertaken. Regimens of antihypertensives that patients were on at the onset and end of the 12 months of back titration were costed in Nigerian currency and compared. Back titration translated to economic benefit in all patients with a cost reduction varying from 2.3% to 100%. This reflected in reduction in mean daily cost of treatment of N107.09-N54.61. The benefit of antihypertensive back titration apart from psychological relief of lower pill burden and side effect profile is in pharmacoeconomics. This permits greater adherence and prevents morbi-mortality consequences of hypertension. In this study, back titration over 12 months translated to average cost reduction of >50%, making treatment more affordable. In appropriate circumstances, back titration of antihypertensives results in economic relief for patients. This should improve adherence, reduce morbi-mortality and is recommended for wider application.

The prevalence of allergic diseases is increasing globally, most particularly in middle- to low-income countries. This article examines the burden of allergic rhinitis and chronic urticaria in the Asia-Pacific region, unmet clinical needs, and the potential role of bilastine in the management of these conditions. An International Advisory Group meeting was convened in association with the Asian Pacific Society of Respirology Annual Congress in November 2014, followed by a literature review, and consensus-based outcomes from the meeting and literature review are described. Regional estimates of the prevalence of allergic rhinitis range from 10% to 50%, while little is known regarding the burden of urticaria in the Asia-Pacific region. A survey of allergy patients in the region identified fast, complete, and long-lasting symptom relief as the medication attributes most important to patients. International treatment guidelines for allergic rhinitis and urticaria advocate the first-line use of second-generation, no-sedating H1-antihistamines, such as bilastine, over their first-generation counterparts and a range of these agents are available to Asia-Pacific patients. The newer agents possess many of the properties of an "ideal" antihistamine (once daily administration, rapid and complete symptom relief, limited potential for drug-drug interactions, minimal side effects). The burgeoning prevalence of allergic diseases in the Asia-Pacific region and the uncontrolled symptoms that these patients experience demand a new antihistamine that offers the highest number of positive features according to the international guidelines.

Medicines receiving a conditional marketing authorization through Medicines Adaptive Pathways to Patients (MAPPs) will be a challenge for payers. The "introduction" of MAPPs is already seen by the European Medicines Agency (EMA) as a fait accompli, with payers not consulted or involved. However, once medicines are approved through MAPPs, they will be evaluated for funding by payers through different activities. These include Health Technology Assessment (HTA) with often immature clinical data and high uncertainty, financial considerations, and negotiations through different types of agreements, which can require monitoring post launch. Payers have experience with new medicines approved through conditional approval, and the fact that MAPPs present additional challenges is a concern from their perspective. There may be some activities where payers can collaborate. The final decisions on whether to reimburse a new medicine via MAPPs will have more variation than for medicines licensed via conventional processes. This is due not only to increasing uncertainty associated with medicines authorized through MAPPs but also differences in legal frameworks between member states. Moreover, if the financial and side-effect burden from the period of conditional approval until granting full marketing authorization is shifted to the post-authorization phase, payers may have to bear such burdens. Collection of robust data during routine clinical use is challenging along with high prices for new medicines during data collection. This paper presents the concept of MAPPs and possible challenges. Concerns and potential ways forward are discussed and a number of recommendations are presented from the perspective of payers.

The first South African National Burden of Disease study quantified the underlying causes of premature mortality and morbidity experienced in South Africa in the year 2000. This was followed by a Comparative Risk Assessment to estimate the contributions of 17 selected risk factors to burden of disease in South Africa. This paper describes the health impact of exposure to four selected environmental risk factors: unsafe water, sanitation and hygiene; indoor air pollution from household use of solid fuels; urban outdoor air pollution and lead exposure. The study followed World Health Organization comparative risk assessment methodology. Population-attributable fractions were calculated and applied to revised burden of disease estimates (deaths and disability adjusted life years, [DALYs]) from the South African Burden of Disease study to obtain the attributable burden for each selected risk factor. The burden attributable to the joint effect of the four environmental risk factors was also estimated taking into account competing risks and common pathways. Monte Carlo simulation-modeling techniques were used to quantify sampling, uncertainty. Almost 24 000 deaths were attributable to the joint effect of these four environmental risk factors, accounting for 4.6% (95% uncertainty interval 3.8-5.3%) of all deaths in South Africa in 2000. Overall the burden due to these environmental risks was equivalent to 3.7% (95% uncertainty interval 3.4-4.0%) of the total disease burden for South Africa, with unsafe water sanitation and hygiene the main contributor to joint burden. The joint attributable burden was especially high in children under 5 years of age, accounting for 10.8% of total deaths in this age group and 9.7% of burden of disease. This study highlights the public health impact of exposure to environmental risks and the significant burden of preventable disease attributable to exposure to these four major environmental risk factors in South Africa. Evidence-based policies and programs must be developed and implemented to address these risk factors at individual, household, and community levels.

Biotransformation is a green and useful tool for sustainable and selective chemical synthesis. However, it often suffers from the toxicity and inhibition from organic substrates or products. Here, we established a hollow fiber membrane bioreactor (HFMB)-based aqueous/organic biphasic system, for the first time, to enhance the productivity of a cascade biotransformation with strong substrate toxicity and inhibition. The enantioselective trans-dihydroxylation of styrene to (S)-1-phenyl-1,2-ethanediol, catalyzed by Escherichia coli (SSP1) coexpressing styrene monooxygenase and an epoxide hydrolase, was performed in HFMB with organic solvent in the shell side and aqueous cell suspension in the lumen side. Various organic solvents were investigated, and n-hexadecane was found as the best for the HFMB-based biphasic system. Comparing to other reported biphasic systems assisted by HFMB, our system not only shield much of the substrate toxicity but also deflate the product recovery burden in downstream processing as the majority of styrene stayed in organic phase while the diol product mostly remained in the aqueous phase. The established HFMB-based biphasic system enhanced the production titer to 143 mM, being 16-fold higher than the aqueous system and 1.6-fold higher than the traditional dispersive partitioning biphase system. Furthermore, the combination of biphasic system with HFMB prevents the foaming and emulsification, thus reducing the burden in downstream purification. HFMB-based biphasic system could serve as a suitable platform for enhancing the productivity of single-step or cascade biotransformation with toxic substrates to produce useful and valuable chemicals.

Gay and bisexual men and other men who have sex with men (MSM) account for more than two thirds of new HIV infections in the U.S., with Black MSM experiencing the greatest burden. Antiretroviral pre-exposure prophylaxis (PrEP) can reduce MSM's vulnerability to HIV infection. Uptake of PrEP has been limited, particularly among racial and ethnic minority MSM. Four semi-structured focus groups with gay and bisexual men and other MSM at risk for HIV infection were convened in Boston and Jackson in late 2013. The analysis plan utilized a within-case, across-case approach to code and analyze emerging themes, and to compare results across the two cities. Participants recruited in Jackson were primarily Black gay men, while Boston participants were mostly non-Hispanic White gay men. Participants in both sites shared concerns about medication side effects and culturally insensitive health care for gay men. Jackson participants described stronger medical mistrust, and more frequently described experiences of anti-gay and HIV related stigma. Multiple addressable barriers to PrEP uptake were described. Information about side effects should be explicitly addressed in PrEP education campaigns. Providers and health departments should address medical mistrust, especially among Black gay and bisexual men and other MSM, in part by training providers in how to provide affirming, culturally competent care. Medicaid should be expanded in Mississippi to cover low-income young Black gay and bisexual men and other MSM.

Child health outcomes in the poor communities are largely affected by the non-availability of essential medicines at government health facilities and non-affordability of prescribed medicines at private retail pharmacies. This phenomenon largely defines health seeking behaviours and health service utilisation patterns of the families of the children. Using observational visits, we examined the shelf-availability of medicines for children less than 5 years of age at a rural health centre and conducted focus group discussions with the mothers to explore the effects of non-availability and non-affordability of medicines. We also validated all information by interviewing the health care providers of the area. We found that erratic and insufficient supply of essential medicines at the government health facility and a limited purchasing power to buy medicines from a retail pharmacy, led to considerable 'financial burden' on the poor people, non-compliance with the treatment, health care seeking from informal health providers and healer shopping. This trend has a serious repercussion on the health seeking behaviours and of course the health outcomes, especially among children. On the users' side, health education and health promotion campaign must be instituted to explain the adverse effects on child health ensure appropriate health care seeking behaviours. For the supply side, the health care authorities must ensure the availability of essential medicines for the children at the government facilities. Local community representatives must be involved in the matters related to medicines stock management at the facility.

Side effects prompt some patients to forego otherwise-beneficial therapies. This study explored which characteristics make side effects particularly aversive. We used a psychometric approach, originating from research on risk perception, to identify the factors (or components) underlying side effect perceptions. Women ( N = 149) aged 40 to 74 years were recruited from a patient registry to complete an online experiment. Participants were presented with hypothetical scenarios in which an effective and necessary medication conferred a small risk of a single side effect (e.g., nausea, dizziness). They rated a broad range of side effects on several characteristics (e.g., embarrassing, treatable). In addition, we collected 4 measures of aversiveness for each side effect: choosing to take the medication, willingness to pay to avoid the side effect (WTP), negative affective attitude associated with the side effect, and how each side effect ranks among others in terms of undesirability. A principal components analysis (PCA) was used to identify the components underlying side effect perceptions. Then, for each aversiveness measure separately, regression analyses were used to determine which components predicted differences in aversiveness among the side effects. The PCA revealed 4 components underlying side effect perceptions: affective challenge (e.g., frightening), social challenge (e.g., disfiguring), physical challenge (e.g., painful), and familiarity (e.g., common). Side effects perceived as affectively and physically challenging elicited the highest levels of aversiveness across all 4 measures. Understanding what side effect characteristics are most aversive may inform interventions to improve medical decisions and facilitate the translation of novel biomedical therapies into clinical practice.

Caregiver burden is an important predictor of quality of life (QoL) among caregivers of stroke patients. While caregiver burden and QoL might be closely related, caregiver burden seems also to be a potential modifier of the associations between patients' and caregivers' characteristics and caregivers' QoL. The purpose of this study was to investigate the effect of caregiver burden in caregivers of hospitalized chronic stroke patients and the predictors of caregivers' QoL by level of caregiver burden. A total of 238 patients and their caregivers were interviewed using questionnaires consisting of the Zarit Burden Interview and the Korean-version of the World Health Organization Quality of Life-BREF. Multiple hierarchical regression analyses were performed to determine the predictors of caregivers' QoL among caregivers stratified by median caregiver burden score (high/low). Caregiver burden had a modifying effect on caregivers' QoL. In caregivers with high burden, the patient characteristics of being unemployed and the caregiver characteristics of poor health status, lower income, and being a spouse were negative predictors of caregivers' QoL. In caregivers with low burden, the patient characteristics of being hospitalized for a longer duration and the caregiver characteristics of poor health status were negative predictors of caregivers' QoL (all ps < 0.05). This study found that in South Korea, more attention should be paid to spouses who are caring for hospitalized chronic stroke patients, particularly with regard to their health status and financial problems. Further studies are needed to examine the impact of factors not examined in the Korean cultural context. Copyright © 2015 Elsevier Inc. All rights reserved.

The determinates of economic burden in lung cancer caregivers are poorly understood. Of particular interest is the role patient symptoms play in caregiver economic burden. Guided by a stress process conceptual framework, this study examined the predictors of economic burden reported by lung cancer spousal caregivers. Our study focused on the pathway of contextual and stressor variables leading to economic burden in lung cancer caregivers. Relying on survey data from 138 spouses, structural equation modeling was employed to examine the determinants of economic burden measured using the Family Impact Survey. Contextual variables included age, gender, education, and income; and stressor variables included patient physical and mental symptoms, as well as number of children in the home. A significant indirect path between age and economic distress through patient symptoms (p = 0.05) indicates younger spouses providing care for patients with more symptoms and reporting greater economic burden. Direct effects between contextual variables and economic burden revealed that caregivers with less education (p = 0.02) and those with more children at home (p = 0.01) reported more adverse economic outcomes. Numerous factors impact spousal caregivers' economic burden, including the presence of children at home, being a younger caregiver, and lower educational attainment by caregivers. Moreover, the direct effects between age and economic burden were not significant, supporting the clear role patient symptoms play in the path to economic burden in spousal caregivers. These results underscore the need for healthcare providers to address psychosocial factors when dealing with patients and families with lung cancer. Specifically, the results highlight the importance of addressing patient symptoms early before they threaten the family's economic well-being.

Objective. To assess the effect of communication style, and frequency and severity of medication side-effects, on pharmacy students' perception of risk of experiencing side effects. Methods. One hundred responses from pharmacy students were obtained using an online survey. Participants were presented with a drug information box containing drug name, drug usage, and one side-effect associated with the drug. Information on side-effect for each drug was presented in one of eight experimental conditions, in a 2 (side-effect frequency: low, high), X2 (side-effect severity: mild, severe) X2 (communication style: verbal, verbal + natural frequency) factorial design. Risk perception of experiencing side effects was measured. Results. Communication style was found to have a significant impact on risk perception depending on the context of frequency and severity associated with the side effect. Conclusion. Communication style plays a significant role in formulating risk perceptions of medication side effects. Training in pharmaceutical counseling should include special emphasis on effective language use.

Informal caregivers (IC) are key to enabling home deaths, where preferred, at the end-of-life. Significant morbidity from advanced cancer can make caregiving burdensome. However, knowledge about the nature of the caregiving burden for caregivers in Singapore is limited. Hence, the key objective in this study was to examine the impact of the caregiving burden on quality of life (QOL), mental health and work capacity among local ICs. Eligible English-speaking ICs of hospitalized advanced cancer patients were recruited through non-random sampling. The Zarit Burden Interview (ZBI), Caregiver Quality of Life Index-Cancer (CQOLC), Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and Work Productivity and Activity Impairment Questionnaire (WPAI) were interviewer-administered to eligible ICs. Altogether, 16 ICs were surveyed. The mean age of ICs was 43.8 years. Most were children of patients (43.8%), and eight ICs had high burden (ZBI > 17). Those with ZBI > 17 had lower QOL, higher depression scores as well as greater work and activity impairment. In conclusion, high caregiver burden has adverse effects on QOL, mental health and work productivity. Non-physical elements of caregiving (particularly financial and decision-making) and increased number of care roles undertaken by a single IC contribute to high burden. Future interventions for caregiving burden in Singapore should also address the financial and decision-making aspects of caregiving. Outsourcing selected aspects of the caregiving role to community services may reduce the number of caregiving aspects undertaken by a single IC and caregiver burden.

Patients with psychotic disorders are often treated with numerous medications, many of which have anticholinergic activity. We assessed cognition in relation to the cumulative anticholinergic burden of multiple drugs included in treatment regimens of participants from the Bipolar-Schizophrenia Network on Intermediate Phenotypes (B-SNIP) study. Clinically stable participants with schizophrenia (n=206), schizoaffective disorder (n=131), and psychotic bipolar disorder (n=146) were examined. Anticholinergic properties of all scheduled drugs were quantified using the Anticholinergic Drug Scale (ADS). ADS scores were summed across individual drugs to create a total ADS burden score for each participant and examined in relation to the Brief Assessment of Cognition in Schizophrenia (BACS). Anticholinergic burden aggregated across all medications was inversely related to cognitive performance starting at ADS scores of 4 in participants with schizophrenia. Those with ADS scores ≥4 had lower composite BACS scores compared to those with ADS<4 (p=0.004). Among BACS subtests, Verbal Memory was the most adversely affected by high anticholinergic burden. Despite similar anticholinergic burden scores across groups, a significant threshold effect of anticholinergic burden was not detected in schizoaffective or psychotic bipolar disorder. We identified an adverse effect threshold of anticholinergic burden on cognition in clinically stable participants with schizophrenia. This relationship was not identified in affective psychoses. Examination of other medications, doses, and clinical measures did not account for these findings. Patients with schizophrenia may have increased cognitive susceptibility to anticholinergic medications and the aggregate effects of one's medication regimen may be important to consider in clinical practice.

As a result of the accelerated growth of the elderly population, reconfiguration of families and member roles, and the increase of mental disorders, it is necessary to investigate the effects of this set of factors on the caregivers of patients with dementia in Mexico. Mental disorders of individuals have a negative impact on their physical and emotional quality of life, leading to greater dependence and making the caring experience a heavy burden. Several studies (none in Mexico) have used either the characteristics of the patient or caregiver to determine the burden, but few studies have included both profiles within a single study. The objective of the present study was to analyze the characteristics of the patients and caregivers associated with caregiver burden. A multicenter study was carried out in six health institutions located in Mexico City, including 175 patients (and their caregivers) diagnosed with different types of dementia. We used the Spanish Caregiver Burden Screen. Descriptive analysis and logistic regressions were used to estimate the effect of the covariates on the caregiver burden. The results showed that patient variables have a greater impact on caregiver burden than caregiver-associated variables. Dysexecutive syndrome, sleep disorders, schooling and caregiver depression are associated with a higher level of caregiver burden. Caregiver burden is a complex phenomenon. The results of the present study showed the need to implement multifactorial interventions targeting the caregiver to reduce the burden, strengthen the skills for patient management to avoid depression, improve patient health, and diminish functional dependence and future hospitalization. © 2013 Japan Geriatrics Society.

Colorectal cancer and the 7th revision of the TNM staging system: review of changes and suggestions for uniform pathologic reporting.

Colorectal cancer (CRC) is a neoplastic disease with a continuously growing incidence in Romania and throughout the world. Although the surgery remains the first line treatment for most of the cases, newly discovered targeted molecular therapies - effective for some patients, but with various side effects and significant financial burden for the national health systems - requires not only stratification of patients in prognostic groups but also evaluation of some non-anatomic factors with major impact on the prognosis and therapeutic strategy. The AJCC/UICC TNM staging system, in his 7th revision, effective for cases diagnosed on or after January 1, 2010, responds to these needs. On the other hand, the role of the pathologist is increasing in terms of workload and amount of information to be included in the pathology report in order to deliver a personalized diagnosis. There are concerns worldwide regarding relevance, validity and completeness of pathologic reporting of CRC in the absence of a uniform reporting format. Therefore, suggestions for a standardized pathology report of CRC are made, based on TNM 7 and recent, up-to-date conclusive published data.

To explore the effect of relationship quality and reciprocity in partnerships on subjective caregiver burden and caregiver satisfaction in partners of persons with a severe physical disability (spinal cord injury). Cross-sectional, observational. Community setting. Caregiving partners of persons with spinal cord injury (N=118). Not applicable. Subjective caregiver burden measured by the Zarit Burden Interview (short form) and caregiver satisfaction measured by a single item on feelings of satisfaction resulting from the caregiver role. Caregiving partners who rated their relationship quality as high encountered less subjective caregiver burden (β=-1.10; 95% confidence interval [CI], -1.47 to -0.72; P<.001) and more caregiver satisfaction (odds ratio [OR], 1.18; 95% CI, 1.01-1.45; P=.049). These associations persisted even after controlling for sociodemographic characteristics, lesion severity of the care receiver, and objective caregiver burden. Partners who indicated high reciprocity in their relationship to the care receiver indicated less subjective caregiver burden and more caregiver satisfaction when relationship quality was excluded from the final models; however, the effect of reciprocity on subjective burden (β=-.38; 95% CI, -3.71 to 2.95; P=.82) and caregiver satisfaction (OR, 1.21; 95% CI, 0.28-5.22; P=.80) disappeared when including relationship quality. Results highlight the importance of relationship quality as a target for couple interventions aimed at reducing subjective caregiver burden and increasing satisfaction in the caregiving role.

Drug therapy is the mainstay of treatment for overactive bladder (OAB), but antimuscarinic agents possess side-effects. These side-effects decrease the patients' quality of life. We therefore assessed the impact of side-effects on health-related quality of life (HR-QoL) through an analysis of EQ-5D questionnaire. This study was designed to investigate the patients' satisfaction by quality weight of health status as affected by the side-effects of OAB medications. Patients who had OAB symptoms lasting longer than 3 months and have experienced side-effects after any antimuscarinic treatments filled in the EQ-5D questionnaire. The enrolled patients had two EQ-5D questionnaires for two different health statuses, i.e., presence or absence of side-effects. Quality weight was calculated using the ED-5D health status score with Korean tariff. One hundred patients were enrolled and completed the HR-QoL questionnaire. The most prevalent side-effect was dry mouth (61%) and 28% patients had dry mouth and constipation concurrently. Most of the patients with side-effects tried to endure and overcome these side-effects (79%), but 10% desired a change in medication, and 6% stopped medication altogether. The quality weight of EQ-5D without side-effects was 0.863, while the quality weight with side-effects was 0.666 (P < 0.001). The VAS score was 79 in patient without side-effects and 57 in those with side-effects, supporting the results of quality weight assessment. Overactive bladder patients may enjoy a better quality of life if side-effects associated with antimuscarinic therapy are fewer. © 2016 John Wiley & Sons Australia, Ltd.

N-Methyl, N-propynyl-2-phenylethylamine (MPPE), a Selegiline Analog, Attenuates MPTP-induced Dopaminergic Toxicity with Guaranteed Behavioral Safety: Involvement of Inhibitions of Mitochondrial Oxidative Burdens and p53 Gene-elicited Pro-apoptotic Change.

Selegiline is a monoamine oxidase-B (MAO-B) inhibitor with anti-Parkinsonian effects, but it is metabolized to amphetamines. Since another MAO-B inhibitor N-Methyl, N-propynyl-2-phenylethylamine (MPPE) is not metabolized to amphetamines, we examined whether MPPE induces behavioral side effects and whether MPPE affects dopaminergic toxicity induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Multiple doses of MPPE (2.5 and 5 mg/kg/day) did not show any significant locomotor activity and conditioned place preference, whereas selegiline (2.5 and 5 mg/kg/day) significantly increased these behavioral side effects. Treatment with MPPE resulted in significant attenuations against decreases in mitochondrial complex I activity, mitochondrial Mn-SOD activity, and expression induced by MPTP in the striatum of mice. Consistently, MPPE significantly attenuated MPTP-induced oxidative stress and MPPE-mediated antioxidant activity appeared to be more pronounced in mitochondrial-fraction than in cytosolic-fraction. Because MPTP promoted mitochondrial p53 translocation and p53/Bcl-xL interaction, it was also examined whether mitochondrial p53 inhibitor pifithrin-μ attenuates MPTP neurotoxicity. MPPE, selegiline, or pifithrin-μ significantly attenuated mitochondrial p53/Bcl-xL interaction, impaired mitochondrial transmembrane potential, cytosolic cytochrome c release, and cleaved caspase-3 in wild-type mice. Subsequently, these compounds significantly ameliorated MPTP-induced motor impairments. Neuroprotective effects of MPPE appeared to be more prominent than those of selegiline. MPPE or selegiline did not show any additional protective effects against the attenuation by p53 gene knockout, suggesting that p53 gene is a critical target for these compounds. Our results suggest that MPPE possesses anti-Parkinsonian potentials with guaranteed behavioral safety and that the underlying mechanism of MPPE requires inhibition of mitochondrial oxidative stress, mitochondrial translocation of p53, and pro-apoptotic process.

Cultural predictors of caregiving burden of Chinese-Canadian family caregivers.

The growth of research knowledge on culturally diverse family caregivers for the aging population lags behind the increase of culturally diverse populations in Canada. This study examines the effects of culture, as manifested through cultural variables, on the caregiving burden of family caregivers in a Chinese-Canadian community. A random sample of 339 Chinese-Canadian caregivers for elderly relatives completed a telephone survey. Results of hierarchical stepwise multiple regression analysis reported the predicting effects of culture-related variables on caregiving burden. The findings indicated that being an immigrant, having a Western or non-Western religion as compared to having no religion, and having a lower level of filial piety, predicted a higher level of caregiving burden. Chinese tradition does not exempt the caregivers from being burdened. Policies and practices should address the needs of family caregivers according to the intra-cultural variations identified in this study.

Explanations for side effect aversion in preventive medical treatment decisions

2008-01-01

Objective Many laypeople demonstrate excessive sensitivity to negative side effects of medical treatments, which may lead them to refuse beneficial therapies. This Internet-based experiment investigated three possible explanations for such “side effect aversion.” One was derived from mental accounting, one examined the mere presence of a side effect, and one focused on computational difficulties. Design Participants (N = 5,379) were presented with a hypothetical cancer preventive treatment situation that was or was not accompanied by one or two small side effects. The side effects were either beneficial or harmful. In all conditions the net absolute risk reduction associated with the treatment was 15%. Main Outcome Measures Participants indicated their willingness to accept treatment and their perceptions of the treatment’s effects on their overall cancer risk. Results Data were consistent only with the “mere presence” explanation of side effect aversion, the idea that side effects act as a strong negative cue that directly affects treatment appraisal. The number of negative side effects did not influence treatment willingness. Conclusion Side effect aversion is a challenge to informed decision making. Specific mechanisms that produce side effect aversion should be identified. PMID:19290712

Termination of pregnancy (TOP) remains a controversial issue, regardless of legislation. Access to services as well as psychological effects may vary across the world. To better understand the psychological effects of TOP, this study describes the circumstances of 102 women who underwent a TOP from two socioeconomic sites in Johannesburg, South Africa, one serving women with few economic resources and the other serving women with adequate resources. The relationship between demographic characteristics, resilience and symptoms of post-traumatic stress disorder (PTSD) and depression before, 1 month after and 3 months after the procedure was also examined. Time since TOP, age, chronic burden, resilience and the interaction of site with religion and site with chronic burden were significant. In addition, site differences were found for religion and chronic burden in predicting depression scores. Women from both sites had significant decreases in depression scores over time. The interaction of time with site was not significant. Higher chronic burden scores correlated with higher depression scores. No variables were significant in the bivariate analysis for PTSD. Resilience, religion and chronic burden emerge as significant variables in women undergoing a first-trimester TOP, and warrant further assessment in studies of this nature.

Predators and competitors of vertebrates can in theory reduce the density of infected nymphs (DIN)-an often-used measure of tick-borne disease risk-by lowering the density of reservoir-competent hosts and/or the tick burden on reservoir-competent hosts. We investigated this possible indirect effect of predators by comparing data from 20 forest plots across the Netherlands that varied in predator abundance. In each plot, we measured the density of questing Ixodes ricinus nymphs (DON), DIN for three pathogens, rodent density, the tick burden on rodents and the activity of mammalian predators. We analysed whether rodent density and tick burden on rodents were correlated with predator activity, and how rodent density and tick burden predicted DON and DIN for the three pathogens. We found that larval burden on two rodent species decreased with activity of two predator species, while DON and DIN for all three pathogens increased with larval burden on rodents, as predicted. Path analyses supported an indirect negative correlation of activity of both predator species with DON and DIN. Our results suggest that predators can indeed lower the number of ticks feeding on reservoir-competent hosts, which implies that changes in predator abundance may have cascading effects on tick-borne disease risk. © 2017 The Authors.

Burden and Cognitive Appraisal of Stroke Survivors' Informal Caregivers: An Assessment of Depression Model With Mediating and Moderating Effects.

Tsai, Yi-Chen; Pai, Hsiang-Chu

2016-04-01

This study proposes and evaluates a model of depression that concerns the role of burden and cognitive appraisal as mediators or moderators of outcomes among stroke survivor caregivers. A total of 105 informal caregivers of stroke survivor completed the self-report measures of Caregiver Burden Inventory, Center for Epidemiologic Studies Depression Scale, and Cognitive Impact of Appraisal Scale. The Glasgow Coma Scale and Barthel Index were used by the researcher to examine the physical functional status of the survivor. Partial least squares (PLS) path modeling was used to estimate the parameters of a depression model that included mediating or moderating effects. The model shows that burden and impact of cognitive appraisal have a significant direct and indirect impact on depression, while survivor physical functional status does not have a direct impact. The model also demonstrates that burden and impact of cognitive appraisal separately play a mediating role between survivor physical functional status and caregiver depression. In addition, cognitive appraisal has a moderating influence on the relationship between burden and depression. Overall, survivor physical functional status, burden, and cognitive appraisal were the predictors of caregiver depression, explaining 47.1% of the variance. This study has shown that burden and cognitive appraisal are mediators that more fully explain the relationship between patient severity and caregiver depression. Copyright © 2015 Elsevier Inc.

Background To explore the relationship between binge eating disorder (BED) and obesity in patients with bipolar disorder (BP). Methods 717 patients participating in the Mayo Clinic Bipolar Biobank completed structured diagnostic interviews and questionnaires for demographic and illness-related variables. They also had weight and height measured to determine body mass index (BMI). The effects of BED and obesity (BMI≥30 kg/m2), as well as their interaction, were assessed on one measure of general medical burden and six proxies of psychiatric illness burden. Results 9.5% of patients received a clinical diagnosis of BED and 42.8% were obese. BED was associated with a significantly elevated BMI. Both BED and obesity were associated with greater psychiatric and general illness burden, but illness burden profiles differed. After controlling for obesity, BED was associated with suicidality, psychosis, mood instability, anxiety disorder comorbidity, and substance abuse comorbidity. After controlling for BED status, obesity was associated with greater general medical comorbidity, but lower substance abuse comorbidity. There were no significant interaction effects between obesity and BED, or BMI and BED, on any illness burden outcome. Limitations There may have been insufficient power to detect interactions between BED and obesity. Conclusions: Among patients with BP, BED and obesity are highly prevalent and correlated, but associated with different profiles of enhanced illness burden. As the association of BED with greater psychiatric illness burden remained significant even after accounting for the effect of obesity, BP with BED may represent a clinically important sub-phenotype.

Side effects of prescribed and nonprescribed psychostimulant use are understudied. The study examined side effects of prescribed and nonprescribed psychostimulant use in a college sample with attention to possible gender differences. 2716 undergraduates (1448 male) between the ages of 17 and 57 years (M = 19.43 years, SD = 1.7 years) completed an online survey that included questions about the subjective side effects of prescribed and nonprescribed psychostimulant use. Results suggested that prescribed users more frequently reported side effects, compared to nonprescribed users. For prescribed users, females more frequently reported appetite, somatic, and anxiety-related side effects compared to males. For nonprescribed users, while females reported more somatic and anxiety-related side effects, males more frequently reported loss of sex drive and sweating as side effects. Conclusions/Importance: These findings suggest prescribed users of psychostimulants more frequently report side effects with prominent gender differences in line with gender roles.

Sexual side effects associated with conventional and atypical antipsychotics.

Compton, M T; Miller, A H

2001-01-01

The sexual side effects of psychotropic medications are becoming increasingly recognized in clinical psychiatry. The magnitude of the problem of sexual side effects associated with antipsychotic medications has yet to be fully elucidated, but a multitude of references in the literature demonstrate the importance of these side effects in both men and women. All currently used antipsychotic medications are associated with sexual side effects of various types. Although each antipsychotic medication may have a specific side effect profile determined by its various receptor affinities and by the degree to which it elevates serum prolactin, there is currently no evidence that specific side effects can be predicted. Sexual side effects can be categorized according to the phase of the sexual response cycle with which they interfere. Suggestions for clinical evaluation and treatment options are provided, including risk factor modification, dose reduction, switching agents, and addition of other agents. Sexual side effects associated with conventional and atypical antipsychotic medications represent an underestimated and understudied set of side effects that may diminish a patient's quality of life and lead to treatment noncompliance. Clinicians prescribing antipsychotic medications should be familiar with the classification, evaluation, and treatment of these side effects.

Coping, subjective burden and anxiety among family caregivers of older dependents.

To investigate relationships between anxiety and stressors,coping and subjective burden and to contribute to defining factors related to anxiety among family caregivers of older dependents. Despite the studies analysing factors related to anxiety in caregivers, there is not enough evidence about this issue. Cross-sectional design. Data from 140 family caregivers (convenience sample) were analysed using descriptive statistics, correlation coefficients and path analysis. Socio-demographic data and several scales (Barthel Index, Short Portable Mental Status Questionnaire, Cummings Neuropsychiatric Inventory, Brief COPE, Caregiver Strain Index and Hamilton Anxiety Rating Scale) were used to collect data. Stressors (psychiatric and psychological symptoms and number of assisted activities of daily living), emotion-focused coping, dysfunctional coping and subjective burden were related to greater anxiety. Subjective burden mediated the effects of psychiatric and psychological symptoms on anxiety and partially mediated the effects of dysfunctional coping on anxiety. Stressors, dysfunctional coping and subjective burden were identified as factors related to anxiety. The mediating role of subjective burden in the relationship between dysfunctional coping and anxiety was supported. The effect of dysfunctional coping on anxiety was independent of the stressors. These conclusions justify several recommendations regarding nursing interventions for family caregivers of older dependents: (1) stressors,dysfunctional coping and subjective burden can be used in clinical practice for early detection of and early intervention for anxiety; (2) to prevent subjective burden and anxiety,approach-coping skills should be promoted through interventions such as problem-solving,positive reappraisal, assertiveness and control of negative thoughts; (3) these interventions for dysfunctional coping should be systematically developed for individuals with dysfunctional coping regardless of the level of stressors and/or the possibility of respite.

Self-reported financial burden of cancer care and its effect on physical and mental health-related quality of life among US cancer survivors.

Cancer-related financial burden has been linked to cancer survivors (CS) forgoing/delaying medical care, skipping follow-up visits, and discontinuing medications. To the authors' knowledge, little is known regarding the effect of financial burden on the health-related quality of life of CS. The authors analyzed 2011 Medical Expenditure Panel Survey data. Financial burden was present if one of the following problems was reported: borrowed money/declared bankruptcy, worried about paying large medical bills, unable to cover the cost of medical care visits, or other financial sacrifices. The following outcomes were evaluated: Physical Component Score (PCS) and Mental Component Score (MCS) of the 12-Item Short-Form Health Survey (SF-12), depressed mood, psychological distress, and worry related to cancer recurrence. The authors also assessed the effect of the number of financial problems on these outcomes. Of the 19.6 million CS analyzed, 28.7% reported financial burden. Among them, the average PCS (42.3 vs 44.9) and MCS (48.1 vs 52.1) were lower for those with financial burden versus those without. In adjusted analyses, CS with financial burden had significantly lower PCS (β = -2.45), and MCS (β = -3.05), had increased odds of depressed mood (odds ratio, 1.95), and were more likely to worry about cancer recurrence (odds ratio, 3.54). Survivors reporting ≥ 3 financial problems reported statistically significant and clinically meaningful differences (≥3 points) in the mean PCS and MCS compared with survivors without financial problems. Cancer-related financial burden was associated with lower health-related quality of life, increased risk of depressed mood, and a higher frequency of worrying about cancer recurrence among CS. © 2015 American Cancer Society.

To assess the burden of statin related muscular symptom in real life. We conducted a wide survey on 10,409 French subjects. Among these, 2850 (27%) had hypercholesterolemia and 1074 were treated with statins. Muscular symptoms were reported by 104 (10%) statin treated patients and led to discontinuation in 30% of the symptomatic patients. The main prescribed statins were low doses rosuvastatin, atorvastatin and simvastatin. Pains were the most commonly described symptoms (87%) but many patients also reported stiffness (62%), cramps (67%), weakness or a loss of strength during exertion (55%). Pain was localized in 70% but mostly described as affecting several muscular groups. Approximately 38% of patients reported that their symptoms prevented even moderate exertion during everyday activities, while 42% of patients suffered major disruption to their everyday life. Muscular symptoms associated with average dosage statin therapy are more frequent than in clinical trials and have a greater impact on patients' life than usually thought.

Currently, drug discovery approaches focus on the design of therapies that alleviate an index symptom by reengineering the underlying biological mechanism in agonistic or antagonistic fashion. For example, medicines are routinely developed to target an essential gene that drives the disease mechanism. Therapeutic overloading where patients get multiple medications to reduce the primary and secondary side effect burden is standard practice. This single-symptom based approach may not be scalable, as we understand that diseases are more connected than random and molecular interactions drive disease comorbidities. In this work, we present a proof-of-concept drug discovery strategy by combining network biology, disease comorbidity estimates, and computational drug repositioning, by targeting the risk factors and comorbidities of peripheral artery disease, a vascular disease associated with high morbidity and mortality. Individualized risk estimation and recommending disease sequelae based therapies may help to lower the mortality and morbidity of peripheral artery disease.

Verruca plana as a complication of CO2 laser treatment: a case report.

PubMed

Winn, Aubrey E; Kentosh, Joshua; Bingham, Jonathan L

2015-04-01

Carbon dioxide (CO2) laser treatment is a common therapeutic modality for many dermatologic conditions. It uses a high energy, infrared beam of light, which selectively targets water-containing tissue resulting in controlled ablative resurfacing. This modality, however, can manifest significant cosmetic side effects. Here we report a case of verruca plana manifesting as a response to CO2 laser treatment. A 74-year-old female with recent Mohs surgery for a basal cell carcinoma, presented for full-face-fractionated CO2 treatment to address her surgical scars in addition to treating her mild diffuse actinic damage. Six weeks post treatment, the patient developed erythematous thin plaques over the areas that had been treated. Histology was consistent with verruca plana. Lesions showed mild improvement with topical tretinoin. Verruca plana are benign and typically self-limited; however, they can present a significant cosmetic burden to patients and are an important complication to consider when performing elective cosmetic procedures.

Dizziness and vertigo are the most common complaints of patients that has a high economic burden on the health system. In modern medicine, treatment for dizziness and vertigo consists of chemical pharmacological therapy. Although these drugs are useful in controlling the disease, their side effects and inefficiency in full control of the disease require the use of complementary medicine in this field. Persian medicine consists of valuable experiences of Persian medicine scholars based on the theory of humors and temperaments. In Persian medicine, 2 types of disease are presented: dizziness (sadar) and vertigo (dovar). Persian medicine physicians expressed a different mechanism of action than modern medicine for these diseases. They believed that accumulation of abnormal humors, reeh (normal bloating) or causative pathologic substances, is the basic cause of sadar and dovar and that the most important treatment is cleansing the body, particularly the head from accumulated substances by bloodletting methods.

Evolution of multidisciplinary brain metastasis management: case study and literature review.

PubMed

2015-06-01

Up to 40 percent of all cancer patients develop brain metastasis (BM) during the course of their disease. Despite advances in diagnosis and therapy, prognosis in patients with BM remains poor for many patients, but for some, survival can be of the order of several years in duration. Difficulty in predicting long-term survivors has created controversy in contemporary management of BM. Minimizing medical and neurocognitive side effects (disease borne or iatrogenic) to enhance functional independence and improving overall quality of life in these individuals requires a coordinated approach of first-line and salvage surgical, chemotherapeutic (cytotoxic, targeted, or immune based), and radiation (whole brain radiotherapy or stereotactic radiosurgery) modalities. This goal needs to be balanced against the more traditional targets of management such as symptom relief, reducing tumor burden, and local tumor control, thereby increasing progression-free survival. This case study and literature review demonstrates the role of various treatment modalities in the management of BM.

Supply-side response to declining heroin purity: fentanyl overdose episode in New Jersey.

PubMed

Hempstead, Katherine; Yildirim, Emel O

2014-06-01

The inelastic price demand observations characteristic of illegal drug markets have led to the conclusion that the burden of a negative supply shock would be completely reflected to consumers. This paper argues that the increasing availability of prescription opioids may threaten heroin sellers' profit margin and force them to find alternative methods to compensate buyers in the event of a supply shock. We investigate the 2006 fentanyl overdose episode in New Jersey and argue that the introduction of non-pharmaceutical fentanyl, its spatial distribution, and the timing of overdose deaths may have been related to trends in heroin purity. Using medical examiner data, as well as data from the Drug Enforcement Administration, Office of Diversion Control on retail sales of prescription opioids in a negative binomial specification, we show that month-to-month fluctuations in heroin purity have a significant effect on fentanyl-related overdoses, particularly in those areas where prescription opioids are highly available.

2015-03-01

Chemical burns are common and may cause significant physical, psychological, social and economic burden. Despite a wide variety of potentially harmful chemicals, important general principals may be drawn in the assessment and initial management of such injuries. Early treatment of chemical burns is crucial and may reduce the period of resulting morbidity. This article reviews the assessment and management of cutaneous chemical burns. Assessment of the patient should be rapid and occur in conjunction with early emergency management. Rapid history and pri-mary and secondary survey may be required to exclude systemic side effects of the injury. Depth of wound assessment is difficult given that necrosis caused by various chemicals can continue despite cessation of exposure. Early management should be conducted with consideration of clinician's safety, and appropriate precautions should be taken. Excluding specific situations and chemical exposure, copious irrigation with water remains the mainstay of early management. Referral to a centre of higher acuity may be required for expert evaluation.

Measuring the burden of preventable diabetic hospitalisations in the Mexican Institute of Social Security (IMSS).

2016-08-02

The prevalence of diabetes among adults in Mexico has increased markedly from 6.7 % in 1994 to 14.7 % in 2015. Although the main diabetic complications can be prevented or delayed with timely and effective primary care, a high percentage of diabetic patients have developed them imposing an important preventable burden on Mexican society and on the health system. This paper estimates the financial and health burden caused by potentially preventable hospitalisations due to diabetic complications in hospitals operated by the largest social security institution in Latin America, the Mexican Institute of Social Security (IMSS), in the period 2007-2014. Hospitalisations in IMSS hospitals whose main cause was a diabetic complication were identified. The financial burden was estimated using IMSS diagnostic-related groups. To estimate the health burden, DALYs were computed under the assumption that patients would not have experienced complications if they had received timely and effective primary care. A total of 322,977 hospitalisations due to five diabetic complications were identified during the period studied, of which hospitalisations due to kidney failure and diabetic foot represent 78 %. The financial burden increased by 8.4 % in real terms between 2007 and 2014. However, when measured as cost per IMSS affiliate, it decreased by 11.3 %. The health burden had an overall decrease of 13.6 % and the associated DALYs in 2014 reached 103,688. Resources used for the hospital treatment of diabetic complications are then not available for other health care interventions. In order to prevent these hospitalisations more resources might need to be invested in primary care; the first step could be to consider the financial burden of these hospitalisations as a potential target for switching resources from hospital care to primary care services. However, more evidence of the effectiveness of different primary care interventions is needed to know how much of the burden could be prevented by better primary care.

Caregiver burden among adults caring for orphaned children in rural South Africa

The AIDS epidemic has created an unprecedented number of orphans. While largely absorbed by extended family, this additional responsibility can weigh heavily on their caregivers. The concept of caregiver burden captures multiple dimensions of well-being (e.g., physical, social and psychological). Measuring the extent and determinants of caregiving burden can inform the design of programmes to ease the negative consequences of caregiving. This study uses the baseline data from a study assessing interventions for orphans and vulnerable adolescents in the Eastern Cape, South Africa. Orphan caregivers (n = 726) completed an adapted version of the 12-item Zarit Burden Interview. In addition to basic caregiver and household demographics, the survey also collected information on AIDS-related illness and recent deaths. Descriptive data are presented, followed by multivariate Poisson regression models to explore factors associated with caregiver burden. Approximately 40% of caregivers reported high levels of orphan caregiving burden. Feelings of stress and inadequacy concerning their care responsibilities as well as anger towards the child were common. Household food insecurity was the most important predictor of orphan caregiving burden (marginal effect = 7.82; p < 0.001 for those reporting severe hunger); income was also a significant determinant. When other AIDS impacts were added to the model, only the AIDS-related illness of the caregiver was significantly associated with burden (marginal effect = 3.77; p < 0.001). This study suggests that caregivers with economic vulnerability and those struggling with their own AIDS-related illness feel most overburdened. These findings are particularly relevant to service providers who must identify caregivers in need of immediate assistance and allocate limited resources effectively. To alleviate caregiver burden, programmes must foster greater economic security (e.g., by facilitating access to social grants or directly providing cash transfers) and coordinate services with home-based care programmes serving the chronically ill.

Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of lenses has been lacking. Among the general lay public, misconceptions on eye-sun protection have been identified. For example, sun protection is mainly ascribed to sunglasses, but less so to clear lenses. Skin malignancies in the periorbital region are frequent, but usual topical skin protection does not include the lids. Recent research utilized exact dosimetry and demonstrated relevant differences in UV burden to the eye and skin at a given ambient irradiation. Chronic UV effects on the cornea and lens are cumulative, so effective UV protection of the eyes is important for all age groups and should be used systematically. Protection of children's eyes is especially important, because UV transmittance is higher at a very young age, allowing higher levels of UV radiation to reach the crystalline lens and even the retina. Sunglasses as well as clear lenses (plano and prescription) effectively reduce transmittance of UV radiation. However, an important share of the UV burden to the eye is explained by back reflection of radiation from lenses to the eye. UV radiation incident from an angle of 135°-150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed. It integrates UV transmission as well as UV reflectance of lenses. The E-SPF® compares well with established skin-sun protection factors and provides clear messages to eye health care providers and to lay consumers.

To investigate the association between traumatic brain injury (TBI)-related brain lesions and long-term caregiver burden in relation to dysexecutive syndrome. National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland. A total of 256 participants: 105 combat veterans with TBI, 23 healthy control combat veterans (HCv), and 128 caregivers. Caregiver burden assessed by the Zarit Burden Interview at 40 years postinjury. Participants with penetrating TBI were compared with HCv on perceived caregiver burden and neuropsychological assessment measures. Data of computed tomographic scans (overlay lesion maps of participants with a penetrating TBI whose caregivers have a significantly high burden) and behavioral statistical analyses were combined to identify brain lesions associated with caregiver burden. Burden was greater in caregivers of veterans with TBI than in caregivers of HCv. Caregivers of participants with lesions affecting cognitive and behavioral indicators of dysexecutive syndrome (ie, left dorsolateral prefrontal cortex and dorsal anterior cingulate cortex) showed greater long-term burden than caregivers of participants with lesions elsewhere in the brain. The TBI-related brain lesions have a lasting effect on long-term caregiver burden due to cognitive and behavioral factors associated with dysexecutive syndrome.

Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

Memory for Medication Side Effects in Younger and Older Adults: The Role of Subjective and Objective Importance

Older adults often experience memory impairments, but can sometimes use selective processing and schematic support to remember important information. The current experiments investigate to what degree younger and healthy older adults remember medication side effects that were subjectively or objectively important to remember. Participants studied a list of common side effects, and rated how negative these effects were if they were to experience them, and were then given a free recall test. In Experiment 1, the severity of the side effects ranged from mild (e.g., itching) to severe (e.g., stroke), and in Experiment 2, certain side effects were indicated as critical to remember (i.e., “contact your doctor if you experience this”). There were no age differences in terms of free recall of the side effects, and older adults remembered more severe side effects relative to mild effects. However, older adults were less likely to recognize critical side effects on a later recognition test, relative to younger adults. The findings suggest that older adults can selectively remember medication side effects, but have difficulty identifying familiar but potentially critical side effects, and this has implications for monitoring medication use in older age.

Traditional Chinese Medicine (TCM) is a complete medical system that has been practiced for more than 3000 years. Prescription number 1 (PN-1) consists of several Chinese medicines and is designed according to TCM theories to treat patients with neuropsychiatric disorders. The evidence of clinical practice suggests the benefit effects of PN-1 on cognitive deficits of dementia patients. We try to prove and explain this by using contemporary methodology and transgenic animal models of Alzheimer's disease (AD). The behavioral studies were developed to evaluate the memory of transgenic animals after intragastric administration of PN-1 for 3 months. Amyloid beta-protein (Aβ) neuropathology was quantified using immunohistochemistry and ELISA. The western blotting was used to detect the levels of plasticity associated proteins. The safety of PN-1 on mice was also assessed through multiple parameters. Results showed that PN-1 could effectively relieve learning and memory impairment of transgenic animals. Possible mechanisms showed that PN-1 could significantly reduce plaque burden and Aβ levels and boost synaptic plasticity. Our observations showed that PN-1 could improve learning and memory ability through multiple mechanisms without detectable side effects on mice. We propose that PN-1 is a promising alternative treatment for AD in the future. PMID:23476695

Sports in pediatric oncology: the role(s) of physical activity for children with cancer.

2014-03-01

Malignant disease and anticancer therapy dramatically affect daily life activities and participation in grassroots and high-performance sports. Specifically in childhood and adolescence such activities are relevant factors of individual development and social life. This review focuses on the inherent reduction of normal physical activity in pediatric oncology because this cutback additionally contributes to the level of burden of malignancies. Maintaining normality requires detailed analyses of disease-related and therapy-related restrictions and their justification. Relevant efforts should be stepped up to maintain physical activity levels during pediatric cancer therapy. Another aspect addresses direct therapeutic implications. Feasibility studies, nonrandomized as well as randomized investigations addressed therapeutic effects in acute hospital care, in bone marrow transplant settings, and in outpatient therapy. The overall summary shows positive effects on clinical and psychosocial outcome. Even if the basis of the data for children is still limited, there will be no doubt about a general impact of physical activity on acute side effects as well as late effects. In the areas of tension between context-related restrictions, the right to maintain normality wherever possible and the positive therapeutic and psychosocial perspectives of sports, strong efforts are needed to support physical activity wherever indicated, clarify contraindications, and overcome structural limitations.

A healthy 40-year-old man, restrained in the front passenger seat, suffered visually disabling blunt ocular trauma following spontaneous release of the passenger side air-bag module, during vehicular deceleration, without an automobile crash. Though the driver-side airbag was also released, the driver was unharmed. The passenger suffered bilateral hyphema, bilateral vitreous hemorrhage and suspected posterior scleral rupture in the left eye and also had an eyebrow laceration, from impact with the dashboard panel covering the air-bag module, which was detached by the force of airbag deployment. This is the first reported case from West Africa and the first case in which part of the airbag module detached to cause additional trauma. This report adds to the growing burden of evidence world-wide, for a review of the safety aspects of the automobile airbag. This case clearly illustrates that although airbags reduce mortality, they carry a high risk of ocular morbidity, even with seat belt restraint. PMID:24791116

Methods for comparing 3D surface attributes

A common task in data analysis is to compare two or more sets of data, statistics, presentations, etc. A predominant method in use is side-by-side visual comparison of images. While straightforward, it burdens the user with the task of discerning the differences between the two images. The user if further taxed when the images are of 3D scenes. This paper presents several methods for analyzing the extent, magnitude, and manner in which surfaces in 3D differ in their attributes. The surface geometry are assumed to be identical and only the surface attributes (color, texture, etc.) are variable. As a case in point, we examine the differences obtained when a 3D scene is rendered progressively using radiosity with different form factor calculation methods. The comparison methods include extensions of simple methods such as mapping difference information to color or transparency, and more recent methods including the use of surface texture, perturbation, and adaptive placements of error glyphs.

The impact of demographic change on the estimated future burden of infectious diseases: examples from hepatitis B and seasonal influenza in the Netherlands

PubMed Central

2012-01-01

Background For accurate estimation of the future burden of communicable diseases, the dynamics of the population at risk – namely population growth and population ageing – need to be taken into account. Accurate burden estimates are necessary for informing policy-makers regarding the planning of vaccination and other control, intervention, and prevention measures. Our aim was to qualitatively explore the impact of population ageing on the estimated future burden of seasonal influenza and hepatitis B virus (HBV) infection in the Netherlands, in the period 2000–2030. Methods Population-level disease burden was quantified using the disability-adjusted life years (DALY) measure applied to all health outcomes following acute infection. We used national notification data, pre-defined disease progression models, and a simple model of demographic dynamics to investigate the impact of population ageing on the burden of seasonal influenza and HBV. Scenario analyses were conducted to explore the potential impact of intervention-associated changes in incidence rates. Results Including population dynamics resulted in increasing burden over the study period for influenza, whereas a relatively stable future burden was predicted for HBV. For influenza, the increase in DALYs was localised within YLL for the oldest age-groups (55 and older), and for HBV the effect of longer life expectancy in the future was offset by a reduction in incidence in the age-groups most at risk of infection. For both infections, the predicted disease burden was greater than if a static demography was assumed: 1.0 (in 2000) to 2.3-fold (in 2030) higher DALYs for influenza; 1.3 (in 2000) to 1.5-fold (in 2030) higher for HBV. Conclusions There are clear, but diverging effects of an ageing population on the estimated disease burden of influenza and HBV in the Netherlands. Replacing static assumptions with a dynamic demographic approach appears essential for deriving realistic burden estimates for informing health policy. PMID:23217094

“So far it’s been choosing which side effects I want or I can deal with”: A grounded theory of HIV treatment side effects among people living with HIV

2016-01-01

Despite the availability of new antiretroviral drugs and the simplification of treatment options, side effects continue to affect people living with HIV. In this paper, we present the findings of a grounded theory study designed to gain a critical understanding of the experience of side effects. Three main categories emerged from the data: the side effects, the experience, and the connections. The first category suggests that we need to change how we think about side effects in order to take into account the context in which they are experienced as well as the types and nature of side effects. The second category puts forward the idea that the experience of side effects is composed of three interrelated processes: becoming with, living with, and dealing with. Finally, the third category points to new connections that are formed with people, things and systems in the presence of side effects. PMID:27867446

The desired (therapeutic) and undesired (side) effects of methylphenidate might have underlying correlations. The aim of this study was to explore the strength and the possible sources of these correlations. One hundred and fifty-seven children with ADHD (6-12 years) were administered placebo and methylphenidate (0.5 mg/kg in a divided b.i.d. dose), each for a one-week period, in a double-blind, crossover trial. Therapeutic response was assessed using the Conners' Global Index for parents (CGI-Parents) and teachers (CGI-Teachers), while side effects were assessed using the Barkley Side Effects Rating Scale (SERS). The side effect profile as assessed by the SERS was similar to that of previous studies with insomnia, decreased appetite, and headaches showing significant treatment effects (p < 0.005). These "somatic/physical" side effects did not correlate with CGI-Parents or CGI-Teachers. However, the side effects of "irritability", "proneness to crying", and "anxiousness" showed significant relationships with CGI-Parents. These "mood/anxiety" side effects showed no significant correlations with the CGI-Teachers. The greater "mood/anxiety" side effects on methylphenidate and placebo, the less the parents observe improvement of their children while treated with methylphenidate. This suggests that the correlations between "mood/anxiety" side effects and poor response to treatment may be driven by observer effects rather than biological commonalities between therapeutic and side effects of methylphenidate.

The heterogeneity in financial and time burden of caregiving to children with chronic conditions.

PubMed

Zan, Hua; Scharff, Robert L

2015-03-01

We examine the financial and time burdens associated with caring for children with chronic conditions, focusing on disparities across types of conditions. Using linked data from the 2003 to 2006 National Health Interview Survey and 2004-2008 Medical Expenditure Panel Survey, we created measures of financial burden (out-of-pocket healthcare costs, the ratio of out-of-pocket healthcare costs to family income, healthcare costs paid by insurance, and total healthcare costs) and time burden (missed school time due to illness or injury and the number of doctor visits) associated with 14 groups of children's chronic conditions. We used the two-part model to assess the effect of condition on financial burden and finite mixture/latent class model to analyze the time burden of caregiving. Controlling for the influences of other socio-demographic characteristics on caregiving burden, children with chronic conditions have higher financial and time burdens relative to caregiving burdens for healthy children. Levels of financial burden and burden sharing between families and insurance system also vary by type of condition. For example, children with pervasive developmental disorder or heart disease have a relatively low financial burden for families, while imposing a high cost on the insurance system. In contrast, vision difficulties are associated with a high financial burden for families relative to the costs borne by others. With respect to time burden, conditions such as cerebral palsy and heart disease impose a low time burden, while conditions such as pervasive developmental disorder are associated with a high time burden. This study demonstrates that differences exist in caregiving burden for children by type of chronic condition. Each condition has a unique profile of time and financial cost burden for families and the insurance system. These results have implications for policymakers and for families' savings and employment decisions.

Risk assessments of toxicants in aquatic environments are typically based on the evaluation of concentrations in water or sediment. However, concentrations in water are highly variable, while the body burden may provide a better time-integrated measure of pesticide exposure and potential effects in aquatic organisms. Here, we quantified pesticide body burdens in a dominant invertebrate species from agricultural streams, Gammarus pulex, compared them pesticide concentrations in water samples, and linked the pesticide contamination with observed ecological effects on macroinvertebrate communities. In total, 19 of 61 targeted analytes were found in the organisms, ranging from 0.037 to 93.94 ng g-1 (wet weight). Neonicotinoids caused the highest toxic pressure among the pesticides detected in G. pulex. Using linear solvation energy relationships (LSERs), we derived equivalent pesticide concentrations in stream water based on the body burden. These equivalent concentrations correlated with the concentrations in water samples collected after run-off (65% of variance explained). Pesticide pressure significantly affected the aquatic macroinvertebrate community structure, expressed as SPEARpesticides, and caused, on average, threefold increased insecticide tolerance in G. pulex as a result of adaptation. The toxic pressure derived from body burden and from water samples similarly explained the change in community structure (68% and 64%). However, the increased tolerance of G. pulex to pesticides was better explained by the toxicity derived from body burden (70%) than by the toxicity from water samples (53%). We conclude that the internal body burden of macroinvertebrates is suitable to assess the overall pesticide exposure and effects in agricultural streams.

Formulary review of therapeutic alternatives for atopic dermatitis: focus on pimecrolimus.

PubMed

Weinberg, Jeffrey M

2005-01-01

Atopic dermatitis (AD), often called eczema, is characterized by intense pruritus, erythema, dry skin, and inflammation. The condition is chronic and relapsing, and often occurs in patients with a family history of the atopic triad (asthma, allergic rhinitis, and AD). Use of topical steroids has been the mainstay of medical treatment for AD. Steroid-free treatments for AD, with a more favorable safety profile, have become available within the past 2 years. Tacrolimus ointment, a topical immunomodulator, became available in early 2001 and is indicated for moderate-to-severe AD. A similar but highly skinselective cytokine inhibitor, pimecrolimus cream 1%, became available in March 2002. Pimecrolimus is indicated for mild-to-moderate AD. The objective of this article is to review the key characteristics that differentiate pimecrolimus from steroids and tacrolimus in the treatment of AD. Using secondary resources, the clinical aspects and conventional treatment strategies for AD are reviewed as are the pivotal clinical studies with pimecrolimus and literature on quality of life and economic burden of disease for AD patients and families. Pimecrolimus is an effective, steroid-sparing therapy for mild-tomoderate AD. Early treatment prevents flares, the agent works quickly to reduce signs and symptoms of more advanced AD, and it is safe and appropriate for intermittent long-term therapy. Pimecrolimus has fewer side effects than topical steroids and a better side-effect profile than tacrolimus. It can also be used as a first-line therapy. In studies with patients aged 2 to 17 years, it has been shown to be particularly effective in improving eczema of the face and neck, and its use may improve quality of life for many patients, especially children. A single-strength dose (1%) is safe and medically beneficial for pediatric, adolescent, and adult patients. The direct drug cost of pimecrolimus compares favorably with tacrolimus, but it is significantly more expensive than generic topical steroid creams.

Impact of Leukoaraiosis Burden on Hemispheric Lateralization of the National Institutes of Health Stroke Scale Deficit in Acute Ischemic Stroke.

2016-01-01

The National Institutes of Health Stroke Scale (NIHSS) awards higher deficit scores for infarcts in the dominant hemisphere when compared with otherwise similar infarcts in the nondominant hemisphere. This has been shown to adversely affect stroke recognition, therapeutic decisions, and outcome. However, factors modifying the association between infarct side and deficit severity are incompletely understood. Thus, we sought to determine whether age and age-related leukoaraiosis alter the relation between NIHSS deficit score and the side and volume of infarction. We studied 238 patients with supratentorial, nonlacunar ischemic infarcts prospectively included in our stroke registry between January 2013 and January 2014. NIHSS deficit severity was assessed at the time of presentation. Infarct volumes were assessed by manual planimetry on diffusion-weighted imaging. Leukoaraiosis burden was graded on fluid-attenuated inversion recovery images according to the Fazekas scale and dichotomized to none-to-mild (0-2) versus severe (3-6). Multivariable linear regression with backward elimination was used to identify independent predictors of the admission NIHSS. Left-hemispheric infarction (P<0.001), severe leukoaraiosis (P=0.001), their interaction term (P=0.005), infarct volume (P<0.001), and sex (P=0.013) were independently associated with the NIHSS deficit. Analysis of the individual NIHSS components showed that severe leukoaraiosis was associated with an increase of the lateralizing components of the NIHSS in patients with right-hemispheric infarction (P<0.05). Severe leukoaraiosis substantially attenuates the classic hemispheric lateralization of the NIHSS deficit by relating to greater NIHSS scores of components that are typically assigned to left hemisphere function. © 2015 American Heart Association, Inc.

Non-Pilot Protection of the HVDC Grid

NASA Astrophysics Data System (ADS)

Badrkhani Ajaei, Firouz

This thesis develops a non-pilot protection system for the next generation power transmission system, the High-Voltage Direct Current (HVDC) grid. The HVDC grid protection system is required to be (i) adequately fast to prevent damages and/or converter blocking and (ii) reliable to minimize the impacts of faults. This study is mainly focused on the Modular Multilevel Converter (MMC) -based HVDC grid since the MMC is considered as the building block of the future HVDC systems. The studies reported in this thesis include (i) developing an enhanced equivalent model of the MMC to enable accurate representation of its DC-side fault response, (ii) developing a realistic HVDC-AC test system that includes a five-terminal MMC-based HVDC grid embedded in a large interconnected AC network, (iii) investigating the transient response of the developed test system to AC-side and DC-side disturbances in order to determine the HVDC grid protection requirements, (iv) investigating the fault surge propagation in the HVDC grid to determine the impacts of the DC-side fault location on the measured signals at each relay location, (v) designing a protection algorithm that detects and locates DC-side faults reliably and sufficiently fast to prevent relay malfunction and unnecessary blocking of the converters, and (vi) performing hardware-in-the-loop tests on the designed relay to verify its potential to be implemented in hardware. The results of the off-line time domain transients studies in the PSCAD software platform and the real-time hardware-in-the-loop tests using an enhanced version of the RTDS platform indicate that the developed HVDC grid relay meets all technical requirements including speed, dependability, security, selectivity, and robustness. Moreover, the developed protection algorithm does not impose considerable computational burden on the hardware.

Framing effects on expectations, decisions, and side effects experienced: the case of influenza immunization.

1996-11-01

To examine the effects of using positive or negative frames to describe influenza vaccine benefits and side effects on patients' expectations, decisions, decisional conflict, and reported side effects. 292 previously unimmunized patients with chronic respiratory or cardiac disease were randomly assigned to receive benefit/risk information that was framed: (1) positively as the percentage who remain free of influenza and have no vaccine side effects, or (2) negatively as the percentage who acquire influenza and have vaccine side effects. Questionnaires elicited expectations, decisions, and decisional conflict. Vaccines were telephoned 3 days later for a self-report of local and systemic side effects and work absenteeism. Both groups had similar immunization rates and decisional conflict scores. The positive frame group had lower and more realistic expectations of vaccine side effects, fewer systemic side effects, and less work absenteeism (p < 0.05). In contrast to previous studies of health care workers, framing did not influence patients' decisions, possibly due to the patients' awareness of their higher risk of influenza complications and greater desire to follow recommendations. The common practice of using negative frames when describing probabilities of side effects may need to be reexamined, considering its deleterious influence on self-reported side effects and work absenteeism.

Leukotriene receptor antagonists (LTRAs) are drugs which have been widely used more than ten years. As the use of LTRAs increases, our knowledge with respect to their side effects increases as well. The objective of our study was to evaluat the observed side effects of LTRAs used in patients with astma. 1024 patients treated only with LTRAs owing to asthma or early wheezing were included in the study for a five-year period. The observed side effects of LTRAs in these patients were retrospectively investigated. The side effects were divided into two parts as psychiatric and non-psychiatric. Among the 1024 cases included in the study, 67.5% of the patients out of 41 with side effects were male, 32.5% were female and the average age was 6.5 years. The rate of patients with asthma was 63.41% and 36.58% of the patients had early wheezing. It was determined that sex, age and diagnosis (early wheezing or asthma) of the patients were ineffective in the emergence of side effects. The average period for the emergence of side effects was the first month. It was observed that hyperactivity was the most frequently observed psychiatric side effect and that abdominal pain was the non-psychiatric side effect. The side effects of LTRAs were common in children. Therefore, patients must be informed at the beginning of the treatment and they must be evaluated at certain intervals.

Caused by the consumption of raw or undercooked freshwater fish containing infective metacercariae of Clonorchis sinensis, human clonorchiasis remains a major public health problem in China. In previous study, we had expressed enolase from C. sinensis (CsENO) on the surface of Bacillus subtilis spore and the recombinant spore induced a pronounced protection in terms of reduced worm burden and eggs per gram feces, suggesting B. subtilis spore as an ideal vehicle for antigen delivery by oral treatment and CsENO as a promising vaccine candidate against clonorchiasis. In the current study, we detected CsENO-specific IgG and IgA levels both in serum and in intestinal mucus from rats orally administrated with B. subtilis spore surface expressing CsENO by ELISA. Lysozyme levels in serum and in intestinal mucus were analyzed too. In addition, IgA-secreting cells in intestine epithelium of the rats were detected by immunohistochemistry assay. The intestinal villi lengths of duodenum, jejunum, and ileum were also measured. Rats orally treated with B. subtilis spore or normal saline were used as controls. Our results showed that, compared with the control groups, oral administration of B. subtilis spore expressing CsENO induced both systemic and local mucosal immune response. The recombinant spores also enhanced non-specific immune response in rats. The spores had no side effect on liver function. Moreover, it might facilitate food utilization and digestion of the rats. Our work will pave the way to clarify the involved mechanisms of protective efficacy elicited by B. subtilis spore expressing CsENO and encourage us to carry out more assessment trails of the oral treated spore to develop vaccine against clonorchiasis.

In this era of a constantly changing landscape of antiviral treatment options for chronic viral hepatitis C (CHC), shared clinical decision-making addresses the need to engage patients in complex treatment decisions. However, little is known about the decision attributes that CHC patients consider when making treatment decisions. We identify key patient-centered decision attributes, and explore relationships among these attributes, to help inform the development of a future CHC shared decision-making aid. Semi-structured qualitative interviews with CHC patients at four Veterans Health Administration (VHA) hospitals, in three comparison groups: contemplating CHC treatment at the time of data collection (Group 1), recently declined CHC treatment (Group 2), or recently started CHC treatment (Group 3). Participant descriptions of decision attributes were analyzed for the entire sample as well as by patient group and by gender. Twenty-nine Veteran patients participated (21 males, eight females): 12 were contemplating treatment, nine had recently declined treatment, and eight had recently started treatment. Patients on average described eight (range 5-13) decision attributes. The attributes most frequently reported overall were: physical side effects (83%); treatment efficacy (79%), new treatment drugs in development (55%); psychological side effects (55%); and condition of the liver (52%), with some variation based on group and gender. Personal life circumstance attributes (such as availability of family support and the burden of financial responsibilities) influencing treatment decisions were also noted by all participants. Multiple decision attributes were interrelated in highly complex ways. Participants considered numerous attributes in their CHC treatment decisions. A better understanding of these attributes that influence patient decision-making is crucial in order to inform patient-centered clinical approaches to care (such as shared decision-making augmented with relevant decision-making aids) that respond to patients' needs, preferences, and circumstances.

Background New highly efficacious direct-acting antiviral (DAA) therapies are available to treat chronic hepatitis C viral (HCV) infection. Real-world, patient-centered data on harms and benefits associated with these therapies are needed. Methods PROP UP is a multi-center prospective observational study that plans to enroll 1,600 patients starting treatment with recently-approved DAA regimens. Informed by extensive input from a HCV patient engagement group who prioritized outcomes most important to them, patient-reported outcomes will be characterized using surveys at five time points: Baseline (T1), treatment week 4 (T2), end of treatment (T3), 12 weeks post-treatment (T4), 12 months post-treatment (T5). Outcomes (1) Changes in side effects, functioning, pre-existing conditions, and out-of-pocket costs during therapy (T1 vs T2/T3); (2) Medication adherence in relation to a history of mental health/substance abuse, treatment regimens, pill burden, reasons for missed doses, and cure rates; (3) Short term impact of cure on functioning and amelioration of symptoms (T1 vs T4); (4) Long-term treatment harms or benefits of cure on symptoms, side effects, pre-existing conditions, and functioning (T1 vs T5). Similarities between regimens will be examined where comparisons are appropriate and meaningful. Conclusion PROP UP complements previous clinical trials by focusing on patient-reported outcomes in a representative sample of patients treated in clinical practice, by collaborating with a patient engagement group, by characterizing the experiences of vulnerable subgroups, and by investigating long-term harms and benefits of treatments. PROP UP is designed to provide novel and detailed information to support informed decision-making for patients and providers contemplating HCV treatment (PCORI CER-1408-20660; NCT02601820).

International Peacekeeping Operations

2017-01-01

This article takes stock of some of the important contributions to the study of peacekeeping (PK). Two key topics stand out: peacekeeping burden sharing and mission effectiveness. For burden sharing, the theoretical foundation is the private provision of public goods and joint products. Implications for burden sharing differ whether financial or troop contributions are being shared, with the latter driven by jointly produced country-specific benefits. Financial burden sharing can also differ between United Nations (UN)-led and non-UN-led peacekeeping operations, wherein country-specific benefits are especially important for the latter. Many articles gauge peacekeeping effectiveness by the mission’s ability to maintain the peace or to protect lives for a set time period. More recently, multiple criteria are raised for evaluating peacekeeping in today’s world of multifaceted peacebuilding operations. PMID:28989181

The aim of this study was to understand the experiences of patients with breast cancer and their involvement during outpatient-based chemotherapy in Hong Kong. The outcome evaluation using a mixed-methods approach is not common in interventional studies of nurse-led chemotherapy care programmes. A qualitative approach could provide a deep understanding of the experiences of patients. A qualitative study was conducted. This is part of a randomized controlled trial of a nurse-led care programme (NCT02228200). Individual interviews were conducted in 2013 with 10 patients with breast cancer after they had completed the chemotherapy. Qualitative content analysis was adopted to analyse the interviews. Chemotherapy affected the patients in different ways. Some participants completed the chemotherapy treatment smoothly with minimum side effects, while others encountered many problems during the treatment, which had a great impact on their lives. Guided by their coping attitudes, which were affected by the Chinese culture, most participants adopted behavioural, social, cognitive and emotional strategies to actively cope with the chemotherapy. A few tolerated the treatment passively. Some thought that the process of undergoing chemotherapy was physically bearable, while some equated it with suffering. Others regarded it as a chance to get a new start. The experience of patients with breast cancer during chemotherapy can be likened to that of going on a hike. They reach the peak through different paths and bear different burdens. Yet, they have to go through until the end, regardless of how much of a burden they bear and how they achieve the peak. © 2017 John Wiley & Sons Ltd.

Medicines receiving a conditional marketing authorization through Medicines Adaptive Pathways to Patients (MAPPs) will be a challenge for payers. The “introduction” of MAPPs is already seen by the European Medicines Agency (EMA) as a fait accompli, with payers not consulted or involved. However, once medicines are approved through MAPPs, they will be evaluated for funding by payers through different activities. These include Health Technology Assessment (HTA) with often immature clinical data and high uncertainty, financial considerations, and negotiations through different types of agreements, which can require monitoring post launch. Payers have experience with new medicines approved through conditional approval, and the fact that MAPPs present additional challenges is a concern from their perspective. There may be some activities where payers can collaborate. The final decisions on whether to reimburse a new medicine via MAPPs will have more variation than for medicines licensed via conventional processes. This is due not only to increasing uncertainty associated with medicines authorized through MAPPs but also differences in legal frameworks between member states. Moreover, if the financial and side-effect burden from the period of conditional approval until granting full marketing authorization is shifted to the post-authorization phase, payers may have to bear such burdens. Collection of robust data during routine clinical use is challenging along with high prices for new medicines during data collection. This paper presents the concept of MAPPs and possible challenges. Concerns and potential ways forward are discussed and a number of recommendations are presented from the perspective of payers. PMID:28878667

Neuropathic pain following surgical treatment for breast cancer with or without chemotherapy is a clinical burden and patients frequently report cognitive, emotional and quality of life impairment. A preclinical study recently showed that memantine administered before surgery may prevent neuropathic pain development and cognitive dysfunction. With a translational approach, a clinical trial has been carried out to evaluate whether memantine administered before and after mastectomy could prevent the development of neuropathic pain, the impairment of cognition and quality of life. A randomized, pilot clinical trial included 40 women undergoing mastectomy in the Oncology Department, University Hospital, Clermont-Ferrand, France. Memantine (5 to 20 mg/day; n = 20) or placebo (n = 20) was administered for four weeks starting two weeks before surgery. The primary endpoint was pain intensity measured on a (0-10) numerical rating scale at three months post-mastectomy. Data analyses were performed using mixed models and the tests were two-sided, with a type I error set at α = 0.05. Compared with placebo, patients receiving memantine showed at three months a significant difference in post-mastectomy pain intensity, less rescue analgesia and a better emotional state. An improvement of pain symptoms induced by cancer chemotherapy was also reported. This study shows for the first time the beneficial effect of memantine to prevent post-mastectomy pain development and to diminish chemotherapy-induced pain symptoms. The lesser analgesic consumption and better well-being of patients for at least six months after treatment suggests that memantine could be an interesting therapeutic option to diminish the burden of breast cancer therapy.

Attention deficit-hyperactive disorder (ADHD) is the most common behavioral disorders during childhood whose treatment is greatly dependent on families; therefore, families of such children should improve their relation with them so that they could enjoy their lives. Hence, this study was conducted to evaluate the effect of Barkley's family-oriented program on the burden of care on such families. This clinical trial was conducted among 64 family care givers for children with ADHD. By simple sampling, samples passing the inclusion criteria were selected and randomly allocated into two groups of control and intervention. The intervention group received Barkley's family education program through 9 sessions; the control group participated in 3 group sessions and expressed their problems and experiences. Data were collected and analyzed using the Zarit Burden Interview. Burden of care was gradually reduced through the study in the intervention group, however, the mean score of burden of care did not have a significant reduction in the control group. Because Barkley's family-oriented program was able to reduce the burden of care in families of children with ADHD, it is recommended to develop similar programs and evaluate them through various studies.

This was a secondary analysis (N = 88) of veterans who participated in a 12-week trial. All veterans were randomized into one of four treatment groups: (a) desipramine/naltrexone, (b) desipramine/placebo, (c) paroxetine/naltrexone, and (d) paroxetine/placebo. The main outcome measure was the frequency of sexual side effects consisting of "decreased sex drive" and/or "impotence" reported by veterans at each weekly visit. Approximately 61% of the veterans reported sexual side effects at least once during the trial, and 26.4% reported sexual side effects throughout the study. There were no significant differences in the frequency of sexual side effects among the four treatment groups. The results were similar when the comparison was made between the two antidepressant groups. There were no significant differences in the reporting of sexual side effects between those receiving desipramine and paroxetine. Also, the comparison between naltrexone and placebo did not alter the results. This is the first study to compare frequency of sexual side effect reporting between paroxetine and desipramine. We found no statistically significant differences in sexual side effect reporting between the two antidepressants. Also, the addition of naltrexone did not show any beneficial effect on the sexual side effect profile.

Johansen, Safora; Cvancarova, Milada; Ruland, Cornelia

Although there is significant evidence that the family caregivers (FCs) of cancer patients can experience significant caregiver burden and symptoms, less is known about the relationships between FCs and patient characteristics that influence caregiver burden. The purpose of this study was to examine the effect of cancer patients' and FCs' symptoms and demographic characteristics on caregiver burden at initiation of the patients' radiation treatment. Two hundred eighty-one dyads of FCs and cancer patients who received a diagnosis of breast, prostate, melanoma, lymphoma, and head and neck cancers were recruited at the beginning of the patients' radiation treatment. Measures of depression, sleep disturbance, fatigue, social support, and self-efficacy were obtained from both FCs and cancer patients. The family caregivers were also assessed for caregiver burden. Associations between patients' and caregivers' symptoms and demographic characteristics and caregiver burden were investigated using multivariate analyses. There were significant associations between caregiver burden and the patient-related variables such as self-efficacy (P = .02), sleep disturbance (P = .03), and social support (P = .04). Among FC-related variables, higher scores of depression (P < .01), fatigue (P < .01), and symptoms (P < .01) were significantly associated with higher caregiver burden. Being a female, either as a patient or FC, increased the likelihood of experiencing fatigue and sleep disturbance. Caregiver burden in FCs is influenced by interplay of patients' and their own symptoms and problems. These interdependencies exist from the beginning of treatment. Nurses should systematically assess the problems and symptoms of the patients and FCs and support them from the time of diagnosis to help prevent symptom development and deterioration.

From burden to depressive symptoms: the case of Chinese-Canadian family caregivers for the elderly.

This study aims to understand the effect of caregiving burden on depressive symptoms in Chinese-Canadian family caregivers, an area on which little research has been conducted. A random sample of 339 Chinese-Canadian caregivers for elderly family members completed a structured telephone survey. The results showed that depressive symptoms were predicted positively by caregiving burden, while caregiving burden was predicted negatively by financial adequacy and positively by the level of activities of daily living (ADL) and instrumental activities of daily living (IADL) caregiving assistance provided. Culturally appropriate strategies are needed to support Chinese family caregivers in order to properly manage caregiving responsibilities, financial needs, and psychological burden.

To establish how the terms recommended by the European Commission to describe side-effect risk in patient information leaflets (PILs) influences expectations of side-effects and to identify factors associated with these side-effect expectations. A cross-sectional online survey was carried out by a market research company. Data were collected in England between 18th March and 1st April 2016. A total of 1003 adults aged between 18 and 65. Self-reported expectation that the described side-effects would affect participants if they took the medicine, measured on a likelihood scale from 1 (very unlikely) to 5 (very likely). Participants formed high expectations of side-effects for "very common" and "common" side-effects, with 51.9% and 45.0% of participants rating these as "very likely" or "likely" to happen to them, respectively. This fell to 8.1% for "uncommon," 5.8% for "rare" and 4.1% for "very rare." For each descriptor, higher expectations of side-effects were more associated with women or being from an ethnic minority, or having less education, a household illness, high perceived sensitivity to medicines or negative beliefs about medicines. The current use of verbal descriptors to communicate side-effect risk in PILs leads to high side-effect expectations. These expectations could contribute to nocebo-induced medication side-effects experienced by patients. Additional work is required to identify ways to improve the way risk information is conveyed in PILs. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Development of a passive air sampler to measure airborne organophosphorus pesticides and oxygen analogs in an agricultural community.

Organophosphorus pesticides are some of the most widely used insecticides in the US, and spray drift may result in human exposures. We investigate sampling methodologies using the polyurethane foam passive air sampling device to measure cumulative monthly airborne concentrations of OP pesticides chlorpyrifos, azinphos-methyl, and oxygen analogs. Passive sampling rates (m(3)d(-1)) were determined using calculations using chemical properties, loss of depuration compounds, and calibration with side-by-side active air sampling in a dynamic laboratory exposure chamber and in the field. The effects of temperature, relative humidity, and wind velocity on outdoor sampling rates were examined at 23 sites in Yakima Valley, Washington. Indoor sampling rates were significantly lower than outdoors. Outdoor rates significantly increased with average wind velocity, with high rates (>4m(3)d(-1)) observed above 8ms(-1). In exposure chamber studies, very little oxygen analog was observed on the PUF-PAS, yet substantial amounts chlorpyrifos-oxon and azinphos methyl oxon were measured in outdoor samples. PUF-PAS is a practical and useful alternative to AAS because it results in little artificial transformation to the oxygen analog during sampling, it provides cumulative exposure estimates, and the measured sampling rates were comparable to rates for other SVOCs. It is ideal for community based participatory research due to low subject burden and simple deployment in remote areas. Copyright © 2014 Elsevier Ltd. All rights reserved.

A comparison of cancer burden and research spending reveals discrepancies in the distribution of research funding.

Ideally, the distribution of research funding for different types of cancer should be equitable with respect to the societal burden each type of cancer imposes. These burdens can be estimated in a variety of ways; "Years of Life Lost" (YLL) measures the severity of death in regard to the age it occurs, "Disability-Adjusted Life-Years" (DALY) estimates the effects of non-lethal disabilities incurred by disease and economic metrics focus on the losses to tax revenue, productivity or direct medical expenses. We compared research funding from the National Cancer Institute (NCI) to a variety of burden metrics for the most common types of cancer to identify mismatches between spending and societal burden. Research funding levels were obtained from the NCI website and information for societal health and economic burdens were collected from government databases and published reports. We calculated the funding levels per unit burden for a wide range of different cancers and burden metrics and compared these values to identify discrepancies. Our analysis reveals a considerable mismatch between funding levels and burden. Some cancers are funded at levels far higher than their relative burden suggests (breast cancer, prostate cancer, and leukemia) while other cancers appear underfunded (bladder, esophageal, liver, oral, pancreatic, stomach, and uterine cancers). These discrepancies indicate that an improved method of health care research funding allocation should be investigated to better match funding levels to societal burden.

Understanding of the relationship between caregiver burden and the degree of behavioural deficits in patients with Alzheimer's disease (AD) is relatively limited. Therefore, it is worthwhile to examine the correlations between the various relevant factors to improve the efficacy of care for patients with AD. The aim of this study was to investigate the specific contributions of frontal lobe dysfunction in AD patients to caregiver burden, while controlling for other predictor variables. Participants included 30 pairs of caregivers and patients with AD. The Zarit Burden Interview and Frontal Assessment Battery were used to measure the caregiver burden and patients' frontal lobe function, respectively. To investigate the effects of frontal lobe dysfunction on caregiver burden, hierarchical regression equations with steps incorporating additional predictor variables were fitted. We also performed a correlation analysis between the individual subdomains of the Zarit Burden Interview and the predictor variables. Our study suggests that the degree of frontal lobe dysfunction in AD patients predicts their caregiver burden, when other factors of daily functional limitations and neuropsychiatric symptoms are controlled. Daily functional limitations and neuropsychiatric symptoms affected caregivers' psychosocial burden, whereas frontal lobe dysfunction affected caregivers' burden due to the increase in the dependency of the patients. Our findings indicate that to ameliorate the disabilities of patients and reduce caregiver burden, there is a need for interventions that focus on psychosocial burdens, as shown in previous studies, as well as on excessive dependency due to frontal lobe dysfunction. © 2017 Japanese Psychogeriatric Society.

PCB body burdens in US women of childbearing age 2001-2002: An evaluation of alternate summary metrics of NHANES data.

An extensive body of epidemiologic data associates prenatal exposure to polychlorinated biphenyls (PCBs) with neurodevelopmental deficits and other childhood health effects. Neurological effects and other adverse health effects may also result from exposure during infancy, childhood, and adulthood. Although manufacture and use of PCBs were banned in the US in 1977, exposure to PCBs is a continuing concern due to the widespread distribution of these compounds in the environment and their persistence. The National Health and Nutrition Examination Survey provides PCB body burden measurements representative of the US population for the years 1999-2002. Interpretation of these data is challenging due to the large number of PCB congeners reported. We examined 6 PCB body burden metrics to identify an approach for summarizing the NHANES data and for characterizing changes over time in potential risks to children's health. We focused on women of childbearing age, defined here as 16-39 years, because in utero exposures have been associated with neurodevelopmental effects, and used only the 2001-2002 data because of higher detection rates. The 6 metrics, each consisting of different combinations of the 9 most frequently detected congeners, were as follows: total PCBs (all 9 congeners); highly chlorinated PCBs (2 congeners); dioxin-like PCBs (3 congeners, weighted by toxic equivalency factors); non-dioxin-like PCBs (6 congeners); a 4-congener metric (PCBs 118, 138, 153, and 180); and PCB-153 alone. The PCB metrics were generally highly correlated with each other. There was a strong association of PCB body burdens with age for all metrics. Median body burdens of Mexican American women were lower than those of non-Hispanic White and non-Hispanic Black women for 5 of the 6 metrics, and there were no significant differences in body burdens between the latter two groups. Body burdens of women with incomes above poverty level were greater than those for lower-income women at the median and 95th percentiles, but the differences were not statistically significant for any metric. We conclude that the 4-congener and total PCBs metrics are the most promising approaches for tracking changes in body burdens over time and for comparing body burdens of different subgroups in NHANES.

We review the current understanding of the burden of dermatological disease through the lens of the Global Burden of Disease project, evaluate the impact of skin disease on quality of life in a global context, explore socioeconomic implications, and finally summarize interventions towards improving quality of dermatologic care in resource-poor settings. The Global Burden of Disease project has shown that skin diseases continue to be the 4 th leading cause of nonfatal disease burden world-wide. However, research efforts and funding do not match with the relative disability of skin diseases. International and national efforts, such as the WHO List of Essential Medicines, are critical towards reducing the socioeconomic burden of skin diseases and increasing access to care. Recent innovations such as teledermatology, point-of-care diagnostic tools, and task-shifting help to provide dermatological care to underserved regions in a cost-effective manner. Skin diseases cause significant non-fatal disability worldwide, especially in resource-poor regions. Greater impetus to study the burden of skin disease in low resource settings and policy efforts towards delivering high quality care are essential in improving the burden of skin diseases.

"There is a chain of connections": using syndemics theory to understand HIV treatment side effects.

PubMed

Gagnon, Marilou

2018-03-12

Side effects are central to the experience of living longer with HIV but rarely have they been studied alone. Unlike other aspects of that experience, like quality of life, treatment adherence, chronicity, episodic disability, aging, health, and viral load suppression, side effects have not benefited from the same level of empirical and theoretical engagement from qualitative researchers. In this paper, we draw on syndemics theory and 50 qualitative interviews to better understand the experience of HIV treatment side effects. Two main categories were identified in the data: side effects as a product and side effects as a risk factor. The first category suggests that side effects are not just the product of taking antiretroviral drugs. They are also the product of particular conditions and tend to cluster with other health problems. The second category puts forward the idea that side effects can act as a syndemic risk factor by exposing PLWH to a greater risk of developing health problems and creating conditions in which psychosocial issues are more likely to emerge. The paper concludes by calling for more research on the complex nature of side effects and for the development of comprehensive approaches for the assessment and management of side effects.

Side effects from hormonal therapy (HT) for breast cancer treatment occur frequently and are associated with worse quality of life and HT non-adherence. Whether improved patient-physician communication is associated with patients' reporting of side effects is unknown. We undertook this study to assess factors associated with women's reports of HT side effects. Between December 2012 and April 2013, we conducted a cross-sectional survey of breast cancer patients undergoing HT in an urban medical center. Descriptive statistics, univariate analyses, and multivariate analyses were used to evaluate associations. Of the 100 participants, 67% reported having HT side effects. However, when prompted, an additional 9% reported experiencing specific HT-related symptoms. Despite very high communication scores, one-third of participants reported they had not discussed side effects with providers. Multivariate analysis showed that after controlling for age, education, race, and medication beliefs, women who had difficulty asking providers for more information were more likely to report side effects (odds ratio 8.27, 95% confidence interval 1.01-69.88). Although HT side effects often occur and are bothersome, patient-provider discussions about side effects remain suboptimal. Providers should actively ask patients about medication side effects so that they can be addressed to improve quality of life and potentially, medication adherence.

Background: There are limited nationally representative estimates of the annual economic burden among survivors of the three most prevalent cancers (colorectal, female breast, and prostate) in both nonelderly and elderly populations in the United States. Methods: The 2008 to 2012 Medical Expenditure Panel Survey data were used to identify colorectal (n = 540), female breast (n = 1568), and prostate (n = 1170) cancer survivors and individuals without a cancer history (n = 109 423). Excess economic burden attributable to cancer included per-person excess annual medical expenditures and productivity losses (employment disability, missed work days, and days stayed in bed). All analyses were stratified by cancer site and age (nonelderly: 18–64 years vs elderly: ≥65 years). Multivariable analyses controlled for age, sex, race/ethnicity, marital status, education, number of comorbidities, and geographic region. All statistical tests were two-sided. Results: Compared with individuals without a cancer history, cancer survivors experienced annual excess medical expenditures (for the nonelderly population, colorectal: $8647, 95% confidence interval [CI] = $4932 to $13 974, P < .001; breast: $5119, 95% CI = $3439 to $7158, P < .001; prostate: $3586, 95% CI = $1792 to $6076, P < .001; for the elderly population, colorectal: $4913, 95% CI = $2768 to $7470, P < .001; breast: $2288, 95% CI = $814 to $3995, P = .002; prostate: $3524, 95% CI = $1539 to $5909, P < .001). Nonelderly colorectal and breast cancer survivors experienced statistically significant annual excess employment disability (13.6%, P < .001, and 4.8%, P = .001) and productivity loss at work (7.2 days, P < .001, and 3.3 days, P = .002) and at home (4.5 days, P < .001, and 3.3 days, P = .003). In contrast, elderly survivors of all three cancer sites had comparable productivity losses as those without a cancer history. Conclusions: Colorectal, breast, and prostate cancer survivors experienced statistically significantly higher economic burden compared with individuals without a cancer history; however, excess economic burden varies by cancer site and age. Targeted efforts will be important in reducing the economic burden of colorectal, breast, and prostate cancer. PMID:26705361

Air pollution effects due to deregulation of the electric industry

NASA Astrophysics Data System (ADS)

Davoodi, Khojasteh Riaz

The Energy Policy Act of 1992 introduced the concept of open-access into the electric utility industry which allows privately-owned utilities to transmit power produced by non-utility generators and independent power producers (IPPs). In April 1996, the Federal Energy Regulatory Commission (FERC) laid down the final rules (Orders No. 888 & No. 889), which required utilities to open their transmission lines to any power producer and charge them no more than what they pay for the use of their own lines. These rules set the stage for the retail sale of electricity to industrial, commercial and residential utility customers; non-utility generators (Nugs); and power marketers. These statutory, regulatory and administrative changes create for the electric utility industry two different forces that contradict each other. The first is the concept of competition among utility companies; this places a greater emphasis on electric power generation cost control and affects generation/fuel mix selection and demand side management (DSM) activities. The second force, which is converse to the first, is that utilities are major contributors to the air pollution burden in the United States and environmental concerns are forcing them to reduce emissions of air pollutants by using more environmentally friendly fuels and implementing energy saving programs. This study evaluates the impact of deregulation within the investor owned electric utilities and how this deregulation effects air quality by investigating the trend in demand side management programs and generation/fuel mix. A survey was conducted of investor owned utilities and independent power producers. The results of the survey were analyzed by analysis of variance and regression analysis to determine the impact to Air Pollution. An air Quality Impact model was also developed in this study. This model consists of six modules: (1) demand side management and (2) consumption of coal, (3) gas, (4) renewable, (5) oil and (6) nuclear sources until the year 2005. Each module was analyzed separately and the result from each module was transferred into the Air Quality Impact model. The model assesses the changes in electricity generation within each module due to deregulation and these changes can then be correlated to the emission of air pollutants in the United States.

The inconsistency in clinician and patient ratings of clozapine-induced side effects underscore the need to supplement clinician-based estimates of side effects with patient-reported ones. The main aims of the study are validation of the Glasgow antipsychotic side-effects scale for clozapine (GASS-C) in Serbian inpatients/outpatients with schizophrenia or schizo-affective disorder and recommendations for its future use, based on common and rare clozapine-associated side-effects. The GASS-C was administered to 95 outpatients/inpatients diagnosed with schizophrenia, schizoaffective, or chronic psychotic disorder. The scale showed good overall reliability, with an internal consistency coefficient of α = 0.84, an average retest coefficient of rho = 0.76, and a Spearman-Brown coefficient of validity of 0.81. Side effects were absent or mild in 64.2% of the patients, moderate in 31.6%, severe in 4.2%; 14% of the subjects considered their symptoms distressing. The most commonly reported side-effects were drowsiness, thirst, frequent urination, and dry mouth. Women reported more side effects than men, and patients not in a relationship reported significantly fewer side effects than patients in a relationship. Results indicate a weak positive correlation (rho = 0.231; p = .025) between severity of side effects and clozapine dose. The GASS-C showed good psychometric characteristics in clinical population of patients on clozapine. In future studies, clozapine serum concentrations should be measured when using the GASS-C to monitor side effects.

Learning to experience side effects after antidepressant intake - Results from a randomized, controlled, double-blind study.

Side effects play a key role in patients' failure to take antidepressants. There is evidence that verbal suggestions and informed consent elicit expectations that can in turn trigger the occurrence of side effects. Prior experience or learning mechanisms are also assumed to contribute to the development of side effects, although their role has not been thoroughly investigated. In this study, we examined whether an antidepressant's side effects can be learned via Pavlovian conditioning. Participants (n = 39) were randomly allocated to one of two groups and were exposed to a classical conditioning procedure. During acquisition, 19 participants received amitriptyline and 20 participants received a placebo pill. Pills were taken for four nights together with a novel-tasting drink. After a washout phase, both groups received a placebo pill together with the novel-tasting drink (evocation). Side effects were assessed via the Generic Assessment of Side Effects Scale prior to acquisition (baseline), after acquisition, and after evocation. A score of antidepressant-specific side effects was calculated. Participants taking amitriptyline reported significantly more antidepressant-specific side effects after acquisition compared to both baseline and the placebo group. After evocation, participants who underwent the conditioning procedure with amitriptyline reported significantly more antidepressant-specific side effects than those who never received amitriptyline, even though both groups received a placebo. Our results indicate that antidepressant side effects can be learned using a conditioning paradigm and evoked via a placebo pill when applied with the same contextual factors as the verum.

Due to stable incidence and improved survival rates, there are an increasing number of patients living with HIV/AIDS in the USA. Although highly effective, current antiretroviral therapies are associated with a variety of side effects. The role side effects play on health outcomes has not been fully examined. The current study assessed the association of medication side effects with (1) self-assessed health status; (2) work productivity and activity impairment; and (3) healthcare resource utilization. Data were from a cross-sectional patient-reported survey fielded in the USA using a dual methodology of Internet and paper questionnaires. A total of 953 patients living with HIV/AIDS who were currently taking a medication for their condition were included in the analyses. The most frequent side effects reported by patients were fatigue (70.72%), diarrhea (62.96%), insomnia (58.97%), dizziness (52.78%), neuropathy (52.68%), joint pain (52.36%), nausea (51.63%), and abdominal pain (50.37%). The presence of each side effect was associated with reduced self-assessed health status, increased productivity loss, increased activity impairment, and increased healthcare resource use. Controlling for CD4 cell counts in regression modeling did little to diminish the impact of side effects. Although not all side effects were associated with all outcomes, every side effect was associated with worse health status, some measure of increased work productivity loss, and/or some measure of increased healthcare resource use. Patients are living longer with HIV and, therefore, spending a greater length of time on treatment. The results of the current study suggest that many of these patients are experiencing a wide array of side effects from these therapies. These side effects have demonstrated a profound association with self-assessed health, work productivity, and healthcare resource use. Improved management of these side effects or development of treatments with a better side effect profile may have a substantial humanistic and economic benefit.

To examine the relationship between several psychological factors and the feeling of burden experienced by caregivers of children with home enteral nutrition. Fifty-six mothers of pediatric patients with chronic diseases requiring long-term home enteral nutrition were recruited. They were asked to respond to specific questionnaires about their anxiety symptoms (State-Trait Anxiety Inventory), psychological distress (SCL-90-R) and feeling of burden (Zarit-scale). Caregivers' feeling of burden was found to be statistically associated to psychological distress (r = .516, p < .001) and trait anxiety (r = .376, p = .005). No significant differences were found between the type of diagnosis and caregiver burden. Regression analysis indicated psychological distress has a partial mediational effect in the relationship between trait anxiety and caregivers' burden. Psychological distress and anxiety show a positive correlation with caregivers' feeling of burden, and may disrupt family well-being. Early identification of high-risk situations is essential in order to plan specific psychosocial aid efficiently.

Smoking and subsequent development of COPD is an ever-increasing epidemic in Arabian Gulf and Middle East countries, with no signs of decline. The important fact to be highlighted is that this COPD epidemic of increasing incidence and prevalence is mostly unrecognized by patients, due to the common attribution of symptoms to "smoker's cough", and the underdiagnosis and undertreatment by physicians because the common signs and symptoms masquerade as asthma. Consequently, there are long-term adverse effects of missing the diagnosis. The purpose of this review article is to focus upon the status of COPD in Arabian Gulf and Middle East countries, stressing the increasing burden of smoking and COPD, to emphasize the specific factors leading to rise in prevalence of COPD, to bring to light the underdiagnosis and undermanagement of COPD, and to treat COPD in conformity with standard guidelines with local and regional modifications. This review ends with suggestions and recommendations to the health department to formulate policies and to generate awareness among the general public about the side effects of smoking and consequences of COPD.

Cancer affects a growing proportion of the population as survival improves. The illness and its treatment brings a substantial burden of symptoms, including pain, anxiety, insomnia, and grief. Here, the uses of hypnosis in the treatment of these cancer-related problems will be reviewed. The utility of measuring hypnotizability in the clinical setting will be discussed. The current neurobiology of hypnotizability and hypnosis will be reviewed. Methods and results of using hypnosis for pain control in acute and chronic settings will be presented. Effects of hypnotic analgesia in specific brain regions associated with pain reduction, notably the dorsal anterior cingulate cortex and the somatosensory cortex, underlies its utility as a potent and side-effect free analgesic. Methods for helping those with cancer to better manage their anxiety, insomnia, and grief will be described. These involve facing disease-related stressors while dissociating the experience from somatic arousal. Given the serious complications of medications widely used to treat pain, anxiety, and insomnia, this article provides methods and an evidence base for wider use of techniques involving hypnosis in cancer care. Altering patients' perception of pain, disease-related stress, and anxiety can help change the reality of their life with cancer.

MUSCULOSKELETAL disease accounts for a large proportion of a general practitioner's (GP's) workload. Proper management can not only improve quality of care, but also increase job satisfaction and reap rewards under the new contract. Osteoporosis creates a huge socioeconomic burden of disease and disability. Identifying high-risk groups in primary care and using preventative treatment can result in a substantial reduction in morbidity and mortality. GPs can help by presenting a unified lifestyle message, advising on fall prevention, and providing effective treatment; in particular, calcium and vitamin D for female nursing home residents. Osteoarthritis is eminently treatable in primary care with a number of management options for GPs, in addition to drug therapy. Glucosamine and chondroitin have few side effects and are worth recommending to patients with mild knee osteoarthritis. Rheumatoid arthritis can cause significant disability, which can be limited by early diagnosis, referral, and treatment. Severe refractory rheumatoid arthritis may warrant referral for consideration of biologic therapy. Assessment of the cardiovascular risk and possible use of statins in rheumatoid patients may reduce their cardiovascular mortality. GPs should aim to help patients to achieve optimum quality of life by using a holistic approach and by allowing maximum choice and control over their disease. PMID:15186570

Significance: Scarring of the skin from burns, surgery, and injury constitutes a major burden on the healthcare system. Patients affected by major scars, particularly children, suffer from long-term functional and psychological problems. Recent Advances: Scarring in humans is the end result of the wound healing process, which has evolved to rapidly repair injuries. Wound healing and scar formation are well described on the cellular and molecular levels, but truly effective molecular or cell-based antiscarring treatments still do not exist. Recent discoveries have clarified the role of skin stem cells and fibroblasts in the regeneration of injuries and formation of scar. Critical Issues: It will be important to show that new advances in the stem cell and fibroblast biology of scarring can be translated into therapies that prevent and reduce scarring in humans without major side effects. Future Directions: Novel therapies involving the use of purified human cells as well as agents that target specific cells and modulate the immune response to injury are currently undergoing testing. In the basic science realm, researchers continue to refine our understanding of the role that particular cell types play in the development of scar.

Smoking and subsequent development of COPD is an ever-increasing epidemic in Arabian Gulf and Middle East countries, with no signs of decline. The important fact to be highlighted is that this COPD epidemic of increasing incidence and prevalence is mostly unrecognized by patients, due to the common attribution of symptoms to “smoker’s cough”, and the underdiagnosis and undertreatment by physicians because the common signs and symptoms masquerade as asthma. Consequently, there are long-term adverse effects of missing the diagnosis. The purpose of this review article is to focus upon the status of COPD in Arabian Gulf and Middle East countries, stressing the increasing burden of smoking and COPD, to emphasize the specific factors leading to rise in prevalence of COPD, to bring to light the underdiagnosis and undermanagement of COPD, and to treat COPD in conformity with standard guidelines with local and regional modifications. This review ends with suggestions and recommendations to the health department to formulate policies and to generate awareness among the general public about the side effects of smoking and consequences of COPD.

Cost burden of viral respiratory infections: issues for formulary decision makers.

PubMed

Bertino, Joseph S

2002-04-22

Viral respiratory infections (VRIs) are a common malady associated with considerable costs in terms of decreased productivity and time lost from work or school, visits to health-care providers, and the amount of drugs prescribed. Both total respiratory illness and rhinovirus infection peak during the fall and spring seasons, although the average percentage of office visits by patients with a rhinovirus infection is moderately high throughout the year. Most common cold remedies are relatively ineffective and may produce side effects that contribute to increased health-care costs. Antibiotic therapy is widely overused and misused despite evidence that antibiotics fail to treat the cause of VRI or prevent secondary bacterial infections. Increasing use of antibiotics has a significant impact on health-care costs and the emergence of antimicrobial resistance. Reasons for overprescribing antibiotics are varied, but they often involve physician and patient attitudes and expectations. Although treatment of VRIs poses challenges for effective formulary management, several steps can be taken to facilitate the introduction of antiviral agents, including patient and provider education, the development of rapid diagnostic tests, and medical-economics studies to determine the true cost of antiviral therapy.

The economics of atrial fibrillation: a time for review and prioritization.

PubMed

Cadilhac, Dominique A

2012-08-01

Stroke associated with atrial fibrillation may occur in up to one third of people who experience an ischemic event, and results in greater stroke severity and poorer health outcomes. The ageing population in developed and developing countries will lead to an increase in the prevalence of atrial fibrillation in society. Detecting people who have atrial fibrillation and ensuring optimal prevention management is essential for reducing the burden of stroke worldwide. There is evidence that use of anticoagulants is inadequate in primary and secondary prevention of stroke. New anticoagulants that have fewer side effects and population screening tools are available. However, there is little information available about the cost-effectiveness of these new options for atrial fibrillation detection and stroke prevention management over current practice. Since resources for spending in health are limited, it is essential that formal economic analyses are undertaken to ensure there are informed and evidence-based decisions on where to best invest stroke prevention resources. It is essential that renewed efforts in the area of atrial fibrillation and options for stroke prevention are undertaken within the public health research community. © 2012 The Author.

Assessment and appraisal of new medical technologies require a balance between the interests of different stakeholders. Final decision should take into account the societal value of new therapies. This perspective paper discusses the socio-economic burden of disease as a specific reimbursement decision-making criterion and calls for the inclusion of it as a counterbalance to the cost-effectiveness and budget impact criteria. Socio-economic burden is a decision-making criterion, accounting for diseases, for which the assessed medical technology is indicated. This indicator is usually researched through cost-of-illness studies that systematically quantify the socio-economic burden of diseases on the individual and on the society. This is a very important consideration as it illustrates direct budgetary consequences of diseases in the health system and indirect costs associated with patient or carer productivity losses. By measuring and comparing the socio-economic burden of different diseases to society, health authorities and payers could benefit in optimizing priority setting and resource allocation. New medical technologies, especially innovative therapies, present an excellent case study for the inclusion of socio-economic burden in reimbursement decision-making. Assessment and appraisal have been greatly concentrated so far on cost-effectiveness and budget impact, marginalizing all other considerations. In this context, data on disease burden and inclusion of explicit criterion of socio-economic burden in reimbursement decision-making may be highly beneficial. Realizing the magnitude of the lost socio-economic contribution resulting from diseases in question could be a reasonable way for policy makers to accept a higher valuation of innovative therapies.

Negative physiological stimulation and sedation side effects are experienced by a significant proportion of consumers who consume alcohol mixed with energy drinks (AmED). Few studies have compared the frequency of side effects between sessions of AmED and sessions of alcohol only within-subject, and none have explored a dose relationship. Explore the occurrence of self-reported physiological stimulant and sedative side effects between sessions of AmED and alcohol only, and at varying ED dosage levels within AmED sessions. A convenience sample of 2953 residents of New South Wales, Australia completed an online survey. N=731 AmED users reported daily caffeine intake, typical alcohol and AmED consumption, and past 12-month experience of physiological stimulation and sedation side effects during AmED and alcohol only sessions. Within-subject analyses compared occurrence of side effects between session types. Hierarchical binary logistic regression analyses explored the association of ED dose during AmED sessions with the experience of physiological side effects. There were greater odds of most stimulant side effects, and lower odds of sedation side effects, during AmED sessions compared to alcohol only sessions. Compared to one ED, consumption of three or more EDs was significantly associated with the majority of both stimulant and alcohol intoxication side effects after controlling for demographics and consumption covariates. AmED is associated with perceived changes in physiological stimulant and sedation side effects of alcohol. Experience of side effects is positively associated with ED dosage. Future research should account for varying ED dosage, and reflect real world consumption levels. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although progress has been made in the treatment of herpes zoster (HZ) and postherpetic neuralgia (PHN), available therapeutic options are only partially effective. Given evidence that a live-attenuated varicella-zoster-virus vaccine is effective at reducing the incidence of HZ, PHN and the burden of illness, policymakers and clinicians are being asked to make recommendations regarding the use of the zoster vaccine. In this report, we summarize the evidence regarding the: (1) burden of illness; (2) vaccine efficacy and safety; and (3) cost-effectiveness of vaccination, to assist evidence-based policy making and guide clinicians in their recommendations. First, there is general agreement that the overall burden of illness associated with HZ and PHN is substantial. Second, the safety and efficacy of the zoster vaccine at reducing the burden of illness due to HZ and the incidence of PHN have been clearly demonstrated in large placebo-controlled trials. However, uncertainty remains about the vaccine's duration of protection. Third, vaccination against HZ is likely to be cost-effective when the vaccine is given at approximately 65 y of age, if vaccine duration is longer than 10 y.

One world health: socioeconomic burden and parasitic disease control priorities.

Torgerson, Paul R

2013-08-01

Parasitic diseases present a considerable socio-economic impact to society. Zoonotic parasites can result in a considerable burden of disease in people and substantive economic losses to livestock populations. Ameliorating the effects of these diseases may consist of attempts at eradicating specific diseases at a global level, eliminating them at a national or local level or controlling them to minimise incidence. Alternatively with some parasitic zoonoses it may only be possible to treat human and animal cases as they arise. The choice of approach will be determined by the potential effectiveness of a disease control programme, its cost and the cost effectiveness or cost benefit of undertaking the intervention. Furthermore human disease burden is being increasingly measured by egalitarian non-financial measures which are difficult to apply to livestock. This adds additional challenges to the assessment of socio-economic burdens of zoonotic diseases. Using examples from the group of neglected zoonotic diseases, information regarding the socio-economic effects is reviewed together with how this information is used in decision making with regard to disease control and treatment.

Recognizing the importance of patient-reported outcomes, this longitudinal, prospective study examined: Changes in health-related quality of life (HRQOL) over seven months following antiepileptic drug (AED) initiation and the relationship of seizures, AED side-effects, and AED type to HRQOL. Parents of 124 children with newly diagnosed epilepsy completed measures of HRQOL and side-effects at each clinic visit. Treatment information was also collected. HRQOL remained stable over time; however, seizures and AED side-effects significantly affected multiple HRQOL domains. Higher seizure activity was associated with decreased Physical HRQOL. Side-effects were negatively associated with all HRQOL domains. Children taking carbamazepine who experienced higher side-effects early in therapy demonstrated declining emotional functioning compared to children experiencing no/some side-effects. AED side-effects, AED type, and seizure frequency were associated with longitudinal HRQOL in children with newly-diagnosed epilepsy. Routine assessment of AED side-effects and HRQOL may be useful for clinical decision making.

Prophylaxis versus treatment: Is there a better way to manage radiotherapy-induced nausea and vomiting?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Horiot, Jean-Claude

Nausea and vomiting are two of the most distressing side effects of radiotherapy and cytotoxic drugs, which currently are often combined to treat moderately advanced and advanced solid tumors. Inadequate control of these symptoms may result in significant patient suffering and decrease in the patient's quality of life, which has been shown to decrease patients' compliance to treatment, with potential impact on disease outcome. It is, therefore, important that radiation oncologists recognize the need for adequate prophylactic treatment of radiation-induced nausea and vomiting (RINV) to avoid the detrimental effects on patients' quality of life, and optimize chances for cure. Themore » 5-hydroxytryptamine type 3 (5-HT{sub 3})-receptor antagonists have been proved to provide effective antiemetic therapy in patients undergoing highly emetogenic radiotherapy. Nevertheless, several large surveys have shown that optimal treatments are not always used. Hence, a risk exists that waiting for RINV symptoms rather than prescribing prophylactic antiemetic treatment may lead to increased patient suffering, poorer disease control, and less cost-effective therapy options. Prophylactic management with an effective 5-HT{sub 3}-receptor antagonist should offer a better treatment option for patients at high to moderate risk of RINV. Adequate control of RINV should contribute to patient compliance to treatment, improved therapy outcomes, and decreased burdens on nursing and health care resources.« less

The present study aimed to evaluate a path analytic model accounting for caregivers' psychological distress that takes into account perceived family cohesion and flexibility, expressed emotion and caregiver's burden associated with the presence of mental illness in the family. 50 first-episode and 50 chronic patients diagnosed with schizophrenia or bipolar disorder (most recent episode manic severe with psychotic features) recruited from the Inpatient Psychiatric Unit of the University Hospital of Heraklion, Crete, Greece, and their family caregivers participated in the study. Family functioning was assessed in terms of cohesion and flexibility (FACES-IV), expressed emotion (FQ), family burden (FBS) and caregivers' psychological distress (GHQ-28). Structural equation modelling was used to evaluate the direct and indirect effects of family dynamics on caregivers' psychological distress. The results showed that neither family cohesion nor family flexibility exerted significant direct effects on caregivers' psychological distress. Instead, the effect of flexibility was mediated by caregivers' criticism and family burden indicating an indirect effect on caregivers' psychological distress. These results apply equally to caregivers of first episode and chronic patients. Family interventions aiming to improve dysfunctional family interactions by promoting awareness of family dynamics could reduce the burden and improve the emotional well-being of family caregivers.

Lack of adequate training and support of primary caregivers of multiple sclerosis (MS) patients is the major factor in causing stress, anxiety, and increase of burden. Therefore, the treatment team members such as psychiatric nurses can help these vulnerable people overcome psychiatric pressures effectively not only through their care and referral role but also through their supportive characteristic, which helps the patients improve their clinical status, together with their social, familial, and work adaptation. Therefore, the researcher tried to identify the effect of a group psycho-education program on the burden family caregivers with MS patients. This is a two-group three-stage clinical trial. The researcher referred to the heads of neurology clinics to present the purpose of the study and to start the sampling. The neurology clinics of AL Zahra University Hospital, and also a Private Neurology Clinic were selected to collect the data of the study. The subjects were randomly selected, and then, assigned to two groups of study and control. Independent t-test showed a significant reduction in family caregivers' burden immediately after and 1-month after intervention in the study group, compared to control. Repeated measure ANOVA showed a significant reduction in caregivers' burden mean score in the study group (P < 0.001). As group psycho-education reduced family caregivers' burden, it is recommended to develop and design other programs for the family caregivers of the patients with MS.

The individual contributions of behavior problems to key and related outcomes in dementia, such as nursing home admission (NHA) or caregiver burden, remain unclear. This study sought to determine the ramifications of temporal change in individual behavior problems when accounting for increases in caregiver burden and time to NHA. Although burden is sometimes conceptualized as an antecedent to NHA, it has also emerged as a relevant outcome in dementia caregiving research. A sample of 4545 dementia caregivers who participated in the Medicare Alzheimer disease Demonstration Evaluation was selected for this secondary analysis. Various patterns of change in individual behavior problems were considered as predictors of increases in caregiver burden and time to NHA over a 3-year period via mixed effects and Cox proportional hazards models, respectively. Caregivers who did not indicate a care recipient's dangerous behavior initially but did so subsequently (ie, an "incident" behavior problem) were more likely to experience increases in burden (P < 0.0026). Alternatively, the persistent occurrence of behavior disturbances (particularly memory problems) emerged as the strongest predictors of time to NHA. The findings of this study suggest the benefit of examining temporal patterns of individual behavioral disturbances, and that incident and persistent problems account for different dementia outcomes over time. Considering the temporal ramifications and potency of specific behavior problems can facilitate the targeted and timely delivery of effective clinical interventions.

Petrova, N N; Kucher, E O

2012-01-01

The impact of treatment side-effects on the compliance was studied in 85 depressive patients with different mental disorders - recurrent depressive disorder, postschizophrenic depression and organic affective disorder. The comparison of objective and subjective evaluations of compliance and a comparative analysis of the level of compliance, with its dependence on the treatment specifics, in different diseases were done. A significant role of efficacy and treatment side-effects was identified. The levels of "mental" and "autonomous" side-effects were highest in the treatment of depression: patients with postschizophrenic depression had the highest risk in respect of maintenance treatment; patients with recurrent depressive disorder and organic (affective) disorder were more tolerant to the treatment side-effects and their treatment, including the maintenance therapy, was rather effective. The compliance of all patients with depression was negatively correlated with the severity of side-effects of pharmacotherapy. The greatest side-effects and the lowest level of compliance were observed in the complex treatment with antidepressants and atypical neuroleptics. The effect of side-effects on the compliance was dependent on their severity and subjective tolerability and, to a lesser extent, on the amount of drugs.

Cytochrome P450 and P-Glycoprotein-Mediated Interactions Involving African Herbs Indicated for Common Noncommunicable Diseases

Herbal remedies are regularly used to complement conventional therapies in the treatment of various illnesses in Africa. This may be because they are relatively cheap and easily accessible and are believed by many to be safe, cause fewer side effects, and are less likely to cause dependency. On the contrary, many herbs have been shown to alter the pharmacokinetics of coadministered allopathic medicines and can either synergize or antagonize therapeutic effects as well as altering the toxicity profiles of these drugs. Current disease burden data point towards epidemiological transitions characterised by increasing urbanization and changing lifestyles, risk factors for chronic diseases like hypertension, diabetes, and cancer which often present as multimorbidities. As a result, we highlight African herb-drug interactions (HDIs) modulated via cytochrome P450 enzyme family (CYP) and P-glycoprotein (P-gp) and the consequences thereof in relation to antihypertensive, antidiabetic, and anticancer drugs. CYPs are enzymes which account for to up to 70% of drug metabolism while P-gp is an efflux pump that extrudes drug substrates out of cells. Consequently, regulation of the relative activity of both CYP and P-gp by African herbs influences the effective drug concentration at the site of action and modifies therapeutic outcomes.

Theme: Parenting/parenthood. As delivering care is an inherent part of becoming parents, providing high-level care to the child with health problems might be a burden for the caregiver. This systematic review investigated the effects of caregiver burden of parents who are primarily responsible for the caring of children with asthma. PubMed, CINAHL, Web of Science and Scopus databases were searched for the studies published between 2000-2015. Key search terms used were 'caregiver', 'burden, 'childhood asthma' and 'parent'. A total of 23 studies were examined for this review. Providing care to the child with asthma affects parents as caregivers negatively. Caregivers of the children with asthma often experience anxiety, fear, disappointment, grief, physical distress and low quality of life as the outcomes of caregiving burden. It is absolutely crucial to determine caregiver burden risks and protective factors since wellness level of caregivers affect the asthma management practices and decisions.

On the basis of the GBD (Global Burden of Disease) 2013 Study, this article provides an overview of the global, regional, and country-specific burden of stroke by sex and age groups, including trends in stroke burden from 1990 to 2013, and outlines recommended measures to reduce stroke burden. It shows that although stroke incidence, prevalence, mortality, and disability-adjusted life-years rates tend to decline from 1990 to 2013, the overall stroke burden in terms of absolute number of people affected by, or who remained disabled from, stroke has increased across the globe in both men and women of all ages. This provides a strong argument that "business as usual" for primary stroke prevention is not sufficiently effective. Although prevention of stroke is a complex medical and political issue, there is strong evidence that substantial prevention of stroke is feasible in practice. The need to scale-up the primary prevention actions is urgent. © 2017 American Heart Association, Inc.

Drug therapeutic indications and side-effects are both measurable patient phenotype changes in response to the treatment. Inferring potential drug therapeutic indications and identifying clinically interesting drug side-effects are both important and challenging tasks. Previous studies have utilized either chemical structures or protein targets to predict indications and side-effects. In this study, we compared drug therapeutic indication prediction using various information including chemical structures, protein targets and side-effects. We also compared drug side-effect prediction with various information sources including chemical structures, protein targets and therapeutic indication. Prediction performance based on 10-fold cross-validation demonstrates that drug side-effects and therapeutic indications are the most predictive information source for each other. In addition, we extracted 6706 statistically significant indication-side-effect associations from all known drug-disease and drug-side-effect relationships. We further developed a novel user interface that allows the user to interactively explore these associations in the form of a dynamic bipartitie graph. Many relationship pairs provide explicit repositioning hypotheses (e.g., drugs causing postural hypotension are potential candidates for hypertension) and clear adverse-reaction watch lists (e.g., drugs for heart failure possibly cause impotence).

Cognition predicts functional competence among individuals with schizophrenia across the lifespan. However, as these individuals age, increasing levels of medical burden may also contribute to functional deficits both directly and indirectly through cognition. Thus, we assessed the relationship among, cognition, medical burden, and functional competence in older individuals with schizophrenia. We analyzed data obtained from 60 community-dwelling participants with schizophrenia and 30 control participants aged 50 or above. Cognition was assessed using the MATRICS Consensus Cognitive Battery (MCCB), functional competence was assessed using the USCD Performance-Based Skills Assessment (UPSA), and medical burden was assessed using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G). Group differences were assessed using independent samples t-tests or chi-square tests. Mediation analyses using bootstrapping techniques were used to assess whether cognition mediated the effects of medical burden on functional competence. Participants with schizophrenia had higher levels of medical burden, cognitive deficits, and functional impairments. In participants with schizophrenia, cognition, but not medical burden, predicted functional competence after adjusting for age, education, gender, clinical symptoms, and anticholinergic burden of medications. In control participants, cognition and medical burden both predicted functional competence after adjusting for age, education, and gender. Further, cognition was found to fully mediate the association between medical burden and functional competence in control participants. Cognition is a robust predictor of functional competence among older individuals with schizophrenia, regardless of medical burden. Cognitive deficits associated with schizophrenia may mask any further cognitive impairment associated with medical burden and its impact on function. Copyright © 2015 Elsevier B.V.

A comparison of cancer burden and research spending reveals discrepancies in the distribution of research funding

PubMed Central

2012-01-01

Background Ideally, the distribution of research funding for different types of cancer should be equitable with respect to the societal burden each type of cancer imposes. These burdens can be estimated in a variety of ways; “Years of Life Lost” (YLL) measures the severity of death in regard to the age it occurs, "Disability-Adjusted Life-Years" (DALY) estimates the effects of non-lethal disabilities incurred by disease and economic metrics focus on the losses to tax revenue, productivity or direct medical expenses. We compared research funding from the National Cancer Institute (NCI) to a variety of burden metrics for the most common types of cancer to identify mismatches between spending and societal burden. Methods Research funding levels were obtained from the NCI website and information for societal health and economic burdens were collected from government databases and published reports. We calculated the funding levels per unit burden for a wide range of different cancers and burden metrics and compared these values to identify discrepancies. Results Our analysis reveals a considerable mismatch between funding levels and burden. Some cancers are funded at levels far higher than their relative burden suggests (breast cancer, prostate cancer, and leukemia) while other cancers appear underfunded (bladder, esophageal, liver, oral, pancreatic, stomach, and uterine cancers). Conclusions These discrepancies indicate that an improved method of health care research funding allocation should be investigated to better match funding levels to societal burden. PMID:22800364

Parental Expectation of Side Effects Following Vaccination Is Self-fulfilling: A Prospective Cohort Study.

One of the major factors contributing to parental refusal of vaccinations is the perception that vaccines cause side effects. Although symptoms are commonly reported following vaccinations, their causes are not always straightforward. Although some may be directly attributable to the vaccine itself, others may reflect pre-existing or coincidental symptoms that are misattributed to the vaccine. To investigate psychological factors associated with parental report of side effects following vaccination with the child influenza vaccine, and parental intention to re-vaccinate one's child the following year. A prospective cohort study was run in primary care practices in London in the 2016-2017 influenza season (ClinicalTrials.gov number NCT02909855). Two hundred seventy parents from 14 practices completed a questionnaire before their child's vaccination. Follow-up questionnaires were completed 3 days after vaccination and one month after vaccination. Parental report of side effects and vaccination intention for the subsequent year were measured. Parental report of side effects was strongly associated with pre-vaccination expectation of side effects. Suggestions received from the media, National Health Service (NHS) vaccination leaflet, and health care workers, as well as uncertainty-related beliefs, perceived sensitivity of the child to medicines, pessimism, and anxiety were also associated with reporting side effects. Side effect report was associated with lower vaccination intention for the following influenza season. Side effect perception following vaccination is influenced by psychological factors, in particular expectations. Perceiving side effects reduces future vaccination intention. Future public health communications should aim to decrease unrealistic expectations of side effects to increase vaccine uptake.

There is increasing concern among primary care practitioners about the use of opioids for chronic pain, including their adverse effects, but little attention has been given to how reports of side effects from prescription medication can contribute to outcomes among patients with chronic pain. The aim of this study was to investigate the impact of frequently reported side effects on mood, disability, and opioid misuse in patients with chronic pain prescribed opioids within primary care. Two hundred (N = 200) patients with chronic pain taking opioids for pain were recruited into the study. All patients completed baseline measures and a monthly side effects checklist once a month for 6 months. Patients were divided evenly based on a median split of the number of endorsed side effects over 6 months. The subjects repeated the baseline measures at the end of the study period. Over time, reports of medication side effects tended to decrease, but differences in frequency of reported side effects from baseline to follow-up (6-month time) were not significant, and the order of the frequency of the reported side effects remained similar. Patients who reported significant medication-related adverse effects reported significantly greater activity interference, negative affect, and catastrophizing compared with those with fewer side effects ( P < 0.01). In addition, those patients with pain who reported more side effects showed significantly higher scores on opioid misuse risk ( P < 0.001). This study demonstrates the important role of monitoring medication-related side effects among patients with chronic pain who are prescribed opioid medication for pain within primary care.

Pretreatment with pyridostigmine bromide (PB) has become part of standard military procedures for protection against the effects of possible chemical warfare attack. The purpose of the work reported here was to quantify the type, intensity and frequency of side effects of low-dose PB, and to examine factors that predict the intensity and frequency of side effects. A double-blind, cross-over, placebo (PL)-controlled design was used. Of the 67 subjects, 33 received 30 mg PB every 8 h for 13 doses, and 34 received 60 mg on the same schedule. Order of PB and PL administration was counterbalanced. Overall, side effects were mild, even at the 60-mg dose level. More side effects were reported when volunteers were taking PB than when they were taking placebo. Women reported more symptoms than men. Neither cholinesterase inhibition nor plasma levels of PB predicted side effect scores during the PB week; the best predictor of side effect scores during the PB week was side effect scores during the PL week. PB is well tolerated by healthy young people, even when twice the recommended military dose is administered.

HIV/AIDS and lipodystrophy: implications for clinical management in resource-limited settings.

Lipodystrophy is a term used to describe a metabolic complication of fat loss, fat gain, or a combination of fat loss and gain, which is associated with some antiretroviral (ARV) therapies given to HIV-infected individuals. There is limited research on lipodystrophy in low- and middle-income countries, despite accounting for more than 95% of the burden of HIV/AIDS. The objective of this review was to evaluate the prevalence, pathogenesis and prognosis of HIV-related lipoatrophy, lipohypertrophy and mixed syndrome, to inform clinical management in resource-limited settings. We conducted a structured literature search using MEDLINE electronic databases. Relevant MeSH terms were used to identify published human studies on HIV and lipoatrophy, lipohypertrophy, or mixed syndrome in low-, low-middle- and upper-middle-income countries through 31 March 2014. The search resulted in 5296 articles; after 1599 studies were excluded (958 reviews, 641 non-human), 3697 studies were extracted for further review. After excluding studies conducted in high-income settings (n=2808), and studies that did not meet inclusion criteria (n = 799), 90 studies were included in this review. Of the 90 studies included in this review, only six were from low-income countries and eight were from lower middle-income economies. These studies focused on lipodystrophy prevalence, risk factors and side effects of antiretroviral therapy (ART). In most studies, lipodystrophy developed after the first six months of therapy, particularly with the use of stavudine. Lipodystrophy is associated with increased risk of cardiometabolic complications. This is disconcerting and anticipated to increase, given the rapid scale-up of ART worldwide, the increasing number and lifespan of HIV-infected patients on long-term therapy, and the emergence of obesity and non-communicable diseases in settings with extensive HIV burden. Lipodystrophy is common in resource-limited settings, and has considerable implications for risk of metabolic diseases, quality of life and adherence. Comprehensive evidence-based interventions are urgently needed to reduce the burden of HIV and lipodystrophy, and inform clinical management in resource-limited settings.

Cancer survivors may experience long-term and late effects from treatment that adversely affect health and limit functioning. Few studies examine lost productivity and disease burden in cancer survivors compared with individuals who have other chronic conditions or by cancer type. We identified 4960 cancer survivors and 64,431 other individuals from the 2008-2010 Medical Expenditure Panel Survey and compared multiple measures of disease burden, including health status and lost productivity, between conditions and by cancer site for cancer survivors. All analyses controlled for the effects of age, sex, race/ethnicity, and number of comorbid conditions. Overall, in adjusted analyses in multiple models, cancer survivors with another chronic disease (heart disease or diabetes) experienced higher levels of burden compared with individuals with a history of cancer only, chronic disease only, and neither cancer, heart disease, nor diabetes across multiple measures (P < .05). Among cancer survivors, individuals with short survival cancers and multiple cancers consistently had the highest levels of burden across multiple measures (P < .0001). Cancer survivors who have another chronic disease experience more limitations and higher levels of burden across multiple measures. Limitations are particularly severe in cancer survivors with short survival cancer and multiple cancers. © 2013 American Cancer Society.

This article aimed to provide an overview regarding the burden of relatives of mentally ill patients and their expectations towards psychiatric institutions. The literature was selected from Medline covering the years 1996 - 2002. 342 articles were reviewed, 145 of which were described in this review. The burden of relatives are manifold and can be classified into the following categories: time spent on caring, financial difficulties, occupational restrictions, detrimental effects on relatives own physical and psychological well-being, reduction in leisure activities, negative effects on social relationships, experiences of discrimination and refusal, deficiencies in information about illness, feelings of not being taken seriously, insufficient service support, long distance to mental health service, emotional burdens of caregivers and difficulties with the patients behaviour. The expectations of the relatives mainly refer to the categories "relationship between staff and relatives", "information about illness" and "establishing of institutions required". The various burdens of relatives and their expectations towards psychiatric services point to necessary improvements of mental health services in the sense of a consumer-oriented psychiatric care.

Depressive disorder is often chronic and recurrent, and results in a heavy psychosocial burden on the families of patients with this disorder. This study aims to examine the effectiveness of brief multifamily psychoeducation designed to alleviate their psychosocial burden. Thirty-two relatives of patients with major depressive disorder participated in an open study testing the effectiveness of brief multifamily psychoeducation. The intervention consisted of four sessions over the course of 6 weeks. Outcome measures focused on emotional distress, care burden and Expressed Emotion (EE). The emotional distress, care burden and EE of the family all showed statistically significant improvements from baseline to after the family intervention. The proportion of relatives scoring 9 or more on K6, which indicates possible depressive or anxiety disorder, decreased from sixteen relatives (50.0%) at baseline, to only 3 relatives (9.3%) after the intervention. This study suggests that brief multifamily psychoeducation is a useful intervention to reduce the psychosocial burden of the relatives of patients with depressive disorder. Further evaluation of family psychoeducation for relatives of patients with depressive disorder is warranted.

Pressures on informal caregivers are likely to increase due to increasing life expectancy and health care costs, which stresses the importance of prevention of subjective burden. The present study examined the correlates of overall subjective burden and multiple burden dimensions among spousal and adult-child caregivers of Dutch older adults, both cross-sectional and longitudinal (12-months follow-up). In 2010 and 2011 baseline and follow-up data was collected in a sample of informal caregivers and care recipients in the Northern provinces of the Netherlands. Subjective burden included 7 burden dimensions and a summary score for overall subjective burden, based on the Care-Related Quality of Life Instrument (CarerQoL-7D). Objective stressors were the time investment in caregiving (hours of household care, personal care, practical care) and the health situation of the care recipient, including multimorbidity, functional limitations (Katz Index of Independence Basic Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL), and cognitive functioning problems (EQ-5D + C). Correlates of subjective burden were evaluated with linear and logistic regression analyses. The sample consisted of 356 caregivers at baseline (43% spousal, 57% adult-child caregivers), and 158 caregivers at follow-up (45% spousal, 55% adult-child caregivers). At baseline and follow-up, spousal caregivers experienced a higher overall subjective burden, and reported more often mental health problems, physical health problems, and problems with combining daily activities, compared to adult-child caregivers. For spousal caregivers, a poorer health situation of the care recipient was associated with higher subjective burden, while adult-child caregivers reported higher levels of subjective burden when their time investment in caregiving was high. Subjective burden at follow-up was mainly explained by baseline subjective burden. These results indicate that for effective caregiver support, it is crucial to take the type of care relationship into account, since the level and correlates of overall subjective burden and burden dimensions varied for spousal and adult-child caregivers. In addition, reducing subjective burden will also positively impact the subjective burden over time.

The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impact fraction index was applied to calculate the avoidable burden in order to prioritize interventions. This index was calculated for theoretical, plausible, and feasible minimum risk level scenarios. The joint effects of the risk factors were then estimated for all the scenarios. The highest avoidable burdens in the theoretical, plausible, and feasible minimum risk level scenarios for the non-use of child restraints on urban roads were 52.25, 28.63, and 46.67, respectively. In contrast, the value of this index for speeding was 76.24, 37.00, and 62.23, respectively, for rural roads. On the basis of the different scenarios considered in this research, we suggest focusing on future interventions to decrease the prevalence of speeding, the non-use of child restraints, the use of cell phones while driving, and helmet disuse, and the laws related to these items should be considered seriously.

This study endeavors to advance the current literature by examining the gender differences in the caregiving experiences and the stress-buffering role of positive aspects of caregiving (PAC) among Chinese spousal caregivers of frail elders in Hong Kong. Forty-nine husband caregivers and 121 wife caregivers of frail elders in Hong Kong (N = 170) responded to the Positive Aspects of Caregiving (PAC) scale, the Zarit Burden Interview (ZBI), the 21-item Depression, Anxiety, and Stress Scales (DASS-21), and demographic questions. These spousal caregivers were diverse in age, and their care receivers were diverse in terms of age and health condition. As predicted, there were significant gender differences in the moderating effects of PAC on the relationships of caregiving burden to depression, anxiety, and overall psychological distress. While PAC significantly buffered the effects of caregiving burden on depression, anxiety, and overall psychological distress for wife caregivers, the moderating effects of PAC were not significant for husband caregivers. Unexpectedly, wife caregivers reported lower PAC, higher caregiving burden, and higher psychological distress. As these findings suggest that PAC is lower but more beneficial for Chinese wife caregivers than Chinese husband caregivers, helping professionals are recommended to use strengths-based interventions that target PAC when working with Chinese wife caregivers.

Analysis of relative importance of side effects of anticancer therapy is extremely useful in the process of clinical decision making. There is evidence that patients' perception of the side effects of anticancer treatments changes over time. Aim of this study was to evaluate the cancer patients' perceptions of physical and non-physical side effects of contemporary anticancer therapy. Four hundred and sixty-four patients entered the study (153 men and 311 women). Participants were asked to rank their side effects in order of distress by using two sets of cards naming physical and non-physical effects, respectively. Influencing factors, including treatment and patient characteristics, were also analysed. Patients ranked the non-physical side effect 'Affects my family or partner' first. 'Constantly tired' and 'Loss of hair' were ranked second and third, respectively. Significant differences from previous studies on this topic emerged. In particular, 'Vomiting', a predominant concern in previous studies, almost disappeared, whereas 'Nausea' and 'Loss of hair' remained important side effects in the patients' perception. Interestingly, marital status was predominant in driving patients' perception, being associated with several side effects ('Constantly tired', 'Loss of appetite', 'Affects my work/Home duties', 'Affects my social activities', 'Infertility'). Other significant factors influencing patient's perception of side effects included age, disease characteristics and ongoing anticancer therapy. This study provided information on current status of patients' perceptions of side effects of anticancer treatment. These results could be used in pre-treatment patient education and counselling.

To investigate the effectiveness of presenting medicine side effect risk information in different forms, including that proposed by UK guidelines [[1] Medicines and Healthcare products Regulatory Agency. Always read the leaflet-Getting the best information with every medicine. (Report of the Committee on Safety of Medicines Working Group on Patient Information). London: The Stationery Office, 2005.]. 134 Cancer Research UK (CRUK) website users were recruited via a 'pop-up'. Using a 2x2 factorial design, participants were randomly allocated to one of four conditions and asked to: imagine they had to take tamoxifen, estimate the risks of 4 side effects, and indicate a presentation mode preference. Those presented with absolute frequencies demonstrated greater accuracy in estimating 2 of 4 side effects, and of any side effect occurring, than those presented with frequency bands. Those presented with combined descriptors were more accurate at estimating the risk of pulmonary embolism than those presented with numeric descriptors only. Absolute frequencies outperform frequency bands when presenting side effect risk information. However, presenting such exact frequencies for every side effect may be much less digestible than all side effects listed under 5 frequency bands. Combined numerical and verbal descriptors may be better than numeric only descriptors when describing infrequent side effects. Information about side effects should be presented in ways that patients prefer, and which result in most accurate risk estimates. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Commonly touched items are likely reservoirs from which patients, health care workers, and visitors may encounter and transfer microbes. A quantitative assessment was conducted of the risk represented by the intrinsic bacterial burden associated with bed rails in a medical intensive care unit (MICU), and how disinfection might mitigate this risk. Bacteria present on the rails from 36 patient beds in the MICU were sampled immediately before cleaning and at 0.5, 2.5, 4.5, and 6.5 hours after cleaning. Beds were sanitized with either a bottled disinfectant (BD; CaviCide) or an automated bulk-diluted disinfectant (ABDD; Virex II 256). The majority of bacteria recovered from the bed rails in the MICU were staphylococci, but not methicillin-resistant Staphylococcus aureus. Vancomycin-resistant enterococci were recovered from 3 beds. Bottled disinfectant reduced the average bacterial burden on the rails by 99%. However, the burden rebounded to 30% of that found before disinfection by 6.5 hours after disinfection. ABDD reduced the burden by an average of 45%, but levels rebounded within 2.5 hours. The effectiveness of both disinfectants was reflected in median reductions to burden of 98% for BD and 95% for ABDD. Cleaning with hospital-approved disinfectants reduced the intrinsic bacterial burden on bed rail surfaces by up to 99%, although the population, principally staphylococci, rebounded quickly to predisinfection levels.

The polychlorinated dibenzofurans (PCDFs) are one group of man-made toxicants for which reasonably extensive data exist relevant to dose-response relationships in humans. Examination of contaminated food oil consumption from the yusho (Japan) poisoning incident indicates the mean uptake or body burden of 2, 3, 4, 7, 8-pentachlorodibenzofuran (PnCDF) equivalents (PEQ) associated with nausea and anorexia to be 4.4 micrograms/kg body wt and that associated with chloracne to be 5.9 micrograms/kg. For the yucheng (Taiwan) poisoning incident, blood measurements for chloracne show a similar body burden of 4.0 micrograms/kg. The latter value is toxicologically equivalent to a 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalent (TEQ) bodymore » burden of 2.0 micrograms/kg body wt or about 150 micrograms for an adult person. This corresponds to an adipose tissue level of about 10 micrograms/kg fat, and is comparable to that known to cause chloracne in rhesus monkeys. These body burdens on a TEQ basis are more than 200 times higher than the average current levels of PCDDs/PCDFs found in North American populations and are the first to relate human body burdens of PCDFs with a known effect and to compare them to animal data. Since the effects reported may not be the most sensitive indicator of human toxicity, lower body burdens could be associated with more subtle toxicological events.« less

Worldwide, injuries are a major public health concern and make a considerable contribution to the disease burden. The present study is a component of the National and Subnational Burden of Diseases, Injuries, and Risk Factors from 1990 to 2013 (NASBOD) study in Iran, which was designed to investigate the burden of most important injuries (road traffic injuries, falls, burns, poisonings and drownings) at the national and sub-national levels in Iran. In this paper we explain definitions, organization, injuries selection process, data sources, data gathering methods, and data analyses of the national and sub-national burden of injuries study in Iran. The burden of most important injuries in current metric of DALYs at the national and sub-national levels in Iran over 1990-2013 will be estimated through comprehensive reviews of either published or national data sources. Statistical modeling will be used to impute the missing data on the burden of selected important injuries for each district-year. The results of present study can help health policy makers to plan more comprehensive and cost-effective strategies at national and sub-national level for prevention and control of burden caused by injuries.

2013-01-01

Side effect similarities of drugs have recently been employed to predict new drug targets, and networks of side effects and targets have been used to better understand the mechanism of action of drugs. Here, we report a large-scale analysis to systematically predict and characterize proteins that cause drug side effects. We integrated phenotypic data obtained during clinical trials with known drug–target relations to identify overrepresented protein–side effect combinations. Using independent data, we confirm that most of these overrepresentations point to proteins which, when perturbed, cause side effects. Of 1428 side effects studied, 732 were predicted to be predominantly caused by individual proteins, at least 137 of them backed by existing pharmacological or phenotypic data. We prove this concept in vivo by confirming our prediction that activation of the serotonin 7 receptor (HTR7) is responsible for hyperesthesia in mice, which, in turn, can be prevented by a drug that selectively inhibits HTR7. Taken together, we show that a large fraction of complex drug side effects are mediated by individual proteins and create a reference for such relations. PMID:23632385

Prediction of Central Nervous System Side Effects Through Drug Permeability to Blood-Brain Barrier and Recommendation Algorithm.

Fan, Jun; Yang, Jing; Jiang, Zhenran

2018-04-01

Drug side effects are one of the public health concerns. Using powerful machine-learning methods to predict potential side effects before the drugs reach the clinical stages is of great importance to reduce time consumption and protect the security of patients. Recently, researchers have proved that the central nervous system (CNS) side effects of a drug are closely related to its permeability to the blood-brain barrier (BBB). Inspired by this, we proposed an extended neighborhood-based recommendation method to predict CNS side effects using drug permeability to the BBB and other known features of drug. To the best of our knowledge, this is the first attempt to predict CNS side effects considering drug permeability to the BBB. Computational experiments demonstrated that drug permeability to the BBB is an important factor in CNS side effects prediction. Moreover, we built an ensemble recommendation model and obtained higher AUC score (area under the receiver operating characteristic curve) and AUPR score (area under the precision-recall curve) on the data set of CNS side effects by integrating various features of drug.

Atrial fibrillation (AF) affects ∼2% of the total population. In order to prevent AF recurrences, many anti-arrhythmic drugs are currently available, but most of them are burdened by serious side effects and suboptimal efficacy. The aim of the present study was to test efficacy and safety of a combination of flecainide and metoprolol in preventing AF clinical recurrences. This study is a monocentric, prospective, randomized, open-blinded trial on 173 patients with a recent episode of paroxysmal or persistent AF. Patients were randomized into group A (flecainide + metoprolol; n = 80), group B (flecainide only; n = 72), or group C (metoprolol only; n = 21). Main exclusion criteria were recent acute coronary syndrome, heart failure New York Heart Association class III-IV, left ventricular ejection fraction <0.40, atrioventricular conduction disorders, and severe bradycardia. Primary endpoint was symptomatic recurrence over 1-year follow-up. Secondary endpoint was quality of life (QoL) over 1-year follow-up, as assessed by the SF-36 and Atrial Fibrillation Severity Scale questionnaires. Combination therapy with flecainide and metoprolol significantly reduced recurrences at 1-year follow-up when compared with flecainide alone in the whole population (66.7 vs. 46.8%; P < 0.001) and in patients with persistent AF (71.1 vs. 43.6%; P = 0.025) while adding beta-blocker therapy to paroxysmal AF showed no benefit over IC anti-arrhythmic drug-only. Patients randomized to combination therapy experienced a significant improvement of QoL when compared with those assigned to a flecainide-only regimen irrespective of AF type. Flecainide-metoprolol combination therapy improves effectiveness of rhythm control in persistent symptomatic AF and increases tolerability, with a concomitant reduction of side effects and a better compliance.

The contribution of specific symptoms on ratings of global illness severity in patients with schizophrenia is not well understood. The present study examined the clinical determinants of clinician and patient ratings of overall illness severity. This study included 1,010 patients with a DSM-IV diagnosis of schizophrenia who participated in the baseline visit of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study conducted between January 2001 and December 2004 and who had available symptom severity, side effect burden, cognition, and community functioning data. Both clinicians and patients completed the 7-point Clinical Global Impressions-Severity of Illness scale (CGI-S), the primary measure of interest in the present study. Symptoms were rated using the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia, and functional status with the Quality of Life Scale. Neurocognition, insight, and medication-related side effects were also evaluated. Clinicians rated illness severity significantly higher than patients (P < .001). There was moderate overlap between CGI-S ratings made by clinicians and patients, with almost one third of patients showing substantial (ie, greater than 1 point) discrepancies with clinician ratings. Clinician-rated CGI-S scores were most strongly associated with positive symptoms, with additional independent contributions made by negative, disorganized, and depressive symptoms, as well as functional outcome (all P values < .01). Patient-rated CGI-S scores, on the other hand, were most closely related to depressive symptoms, with additional independent contributions made by positive and anxiety symptoms, clinical insight, and neurocognition (all P values < .01). Depressive symptoms were the strongest predictor of patient-rated CGI-S scores even in patients with good clinical insight (P < .001). Patient and clinician views of overall illness severity are not necessarily interchangeable and differ in their clinical correlates. Taking these differences into account may enhance patient engagement in care and improve outcomes. ClinicalTrials.gov identifier: NCT00014001. © Copyright 2014 Physicians Postgraduate Press, Inc.

Objective To compare a 2 day bowel preparation regime of barium, iodine and a mild stimulant laxative with a 1 day iodine-only regime for CT colonography (CTC). Methods 100 consecutive patients underwent CTC. The first 50 patients (Regime 1) ingested 1 bisacodyl tablet twice a day 3 days before CTC and 1 dose each of 50 ml of barium and 20 ml of iodinated contrast per day starting 2 days before CTC. The second 50 patients (Regime 2) ingested 3 doses of iodinated contrast over 24 h prior to CTC. Volumes of residual stool and fluid, and the effectiveness of stool and fluid tagging, were graded according to methods established by Taylor et al (Taylor S, Slaker A, Burling D, Tam E, Greenhalgh R, Gartner L, et al. CT colonography: optimisation, diagnostic performance and patient acceptability of reduced-laxative regimens using barium-based faecal tagging. Eur Radiol 2008; 18: 32–42). A 3 day low-residue diet was taken by both cohorts. Questionnaires rating the side-effects and burden of the bowel preparation were compared to a control cohort of patients undergoing barium enema. Results The proportion of colons producing none/scattered stool (score 1) was 90.3% with Regime 1 and 65.0% with Regime 2 (p<0.005). Any residual stool was significantly better tagged with Regime 1 (score 5), with 91.7% of Regime 1 exhibiting optimum tagging vs 71.3% of Regime 2 (p<0.05). No significant differences in side-effects between the bowel preparation regimes for CTC were elicited. Bowel preparation for barium enema was tolerated significantly worse than both of the CTC bowel preparation regimes. Conclusion Regime 1, containing a 3 day preparation of a mild laxative, barium and iodine, produced a significantly better prepared colon, with no difference in patient acceptability. PMID:22422379

2014-01-01

In silico prediction of drug side-effects in early stage of drug development is becoming more popular now days, which not only reduces the time for drug design but also reduces the drug development costs. In this article we propose an ensemble approach to predict drug side-effects of drug molecules based on their chemical structure. Our idea originates from the observation that similar drugs have similar side-effects. Based on this observation we design an ensemble approach that combine the results from different classification models where each model is generated by a different set of similar drugs. We applied our approach to 1385 side-effects in the SIDER database for 888 drugs. Results show that our approach outperformed previously published approaches and standard classifiers. Furthermore, we applied our method to a number of uncharacterized drug molecules in DrugBank database and predict their side-effect profiles for future usage. Results from various sources confirm that our method is able to predict the side-effects for uncharacterized drugs and more importantly able to predict rare side-effects which are often ignored by other approaches. The method described in this article can be useful to predict side-effects in drug design in an early stage to reduce experimental cost and time. PMID:25327524

Insufficient sleep in school-aged children is common in modern society, with homework burden being a potential risk factor. The aim of this article is to explore the effect of sleep hygiene on the association between homework and sleep duration. Children filled out the Chinese version of the Adolescent Sleep Hygiene Scale, and parents filled out a sociodemographic questionnaire. The final sample included 363 boys and 371 girls with a mean age of 10.82 ± 0.38 years. Children with more homework went to bed later and slept less. Better sleep hygiene was associated with earlier bedtimes and longer sleep duration. Findings suggest that homework burden had a larger effect on sleep duration than sleep hygiene. Fifth-grade children in Shanghai have an excessive homework burden, which overwrites the benefit of sleep hygiene on sleep duration.

Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side-effects are common. No validated self-rating scale measuring side-effects to CPAP treatment exists today. The aim was to develop the side-effects to CPAP treatment inventory (SECI), and investigate the validity and reliability of the instrument among patients with OSAS. SECI was developed on the basis of: (1) in-depth interviews with 23 patients; (2) examination of the scientific literature and (3) consensus agreement of a multi-professional expert panel. This yielded 15 different types of side-effects related to CPAP treatment. Each side-effect has three sub-questions (scales): perceived frequency (a) and magnitude (b) of the side-effect, as well as its perceived impact on CPAP use (c). A cross-sectional descriptive design was used. A total of 329 patients with OSAS with an average use of CPAP treatment for 39 months (2 weeks to 182 months) were recruited. Data were collected with SECI, and obtained from medical records (clinical variables and data related to CPAP treatment). Construct validity was confirmed with factor analysis (principal component analysis with orthogonal rotation). A logical two-factor solution, the device subscale and symptom subscale, emerged across all three scales. The symptom subscale describing physical and psychological side-effects and the device subscale described mask and device-related side-effects. Internal consistency reliability of the three scales was good (Cronbach's α = 0.74-0.86) and acceptable for the subscales (Cronbach's α = 0.62-0.86). The satisfactory measurement properties of this new instrument are promising and indicate that SECI can be used to measure side-effects to CPAP treatment. © 2010 European Sleep Research Society.

Mood disorder accounts for 13 % of global disease burden. And while therapeutic agents are available, usually orally administered, most have unwanted side effects, and thus making the inhalation of essential oils (EOs) an attractive alternative therapy. Rosmarinus officinalis EO (ROEO), Mediterranean ROEO reported to improve cognition, mood, and memory, the effect on stress of which has not yet been determined. Here, the anti-stress effect of ROEO on stress was evaluated in vivo and in vitro. Six-week-old male ICR mice were made to inhale ROEO and subjected to tail suspension test (TST). To determine the neuronal differentiation effect of ROEO in vitro, induction of ROEO-treated PC12 cells differentiation was observed. Intracellular acetylcholine and choline, as well as the Gap43 gene expression levels were also determined. Inhalation of ROEO significantly decreased the immobility time of ICR mice and serum corticosterone level, accompanied by increased brain dopamine level. Determination of the underlying mechanism in vitro revealed a PC12 differentiation-induction effect through the modulation of intracellular acetylcholine, choline, and Gap43 gene expression levels. ROEO activates the stress response system through the NGF pathway and the hypothalamus-pituitary-adrenal axis, promoting dopamine production and secretion. The effect of ROEO may be attributed to its bioactive components, specifically to α-pinene, one of its major compounds that has anxiolytic property. The results of this study suggest that ROEO inhalation has therapeutic potential against stress-related psychiatric disorders.

In order to classify the caregivers at high risk of increase in their burden early, linear discriminant analysis was performed to obtain an effective discriminant model for differentiation of the presence or absence of increase in caregiver burden. The data obtained by self-administered questionnaire from 193 caregivers of frail elderly from January to February of 2005 were used. The discriminant analysis yielded a statistically significant function explaining 35.0% (Rc=0.59; d.f.=6; p=0.0001). The configuration indicated that the psychological predictors of change in caregiver burden with much perceived stress (1.47), high caregiver burden at baseline (1.28), emotional control (0.75), effort to achieve (-0.28), symptomatic depression (0.20) and "ikigai" (purpose in life) (0.18) made statistically significant contributions to the differentiation between no increase and increase in caregiver burden. The discriminant function showed a sensitivity of 86% and specificity of 81%, and successfully classified 83% of the caregivers. The function at baseline is a simple and useful method for screening of an increase in caregiver burden among caregivers for the frail elderly at home.

Rural South Africa (SA) is undergoing a rapid health transition characterized by increases in non-communicable diseases; stroke in particular. Knowledge of the relative contribution of modifiable risk factors on disease occurrence is needed for public health prevention efforts and community-oriented health promotion. Our aim was to estimate the burden of stroke in rural SA that is attributable to high blood pressure, excess weight and high blood glucose using World Health Organization's comparative risk assessment (CRA) framework. We estimated current exposure distributions of the risk factors in rural SA using 2010 data from the Agincourt health and demographic surveillance system (HDSS). Relative risks of stroke per unit of exposure were obtained from the Global Burden of Disease Study 2010. We used data from the Agincourt HDSS to estimate age-, sex-, and stroke specific deaths and disability adjusted life years (DALYs). We estimated the proportion of the years of life lost (YLL) and DALY loss attributable to the risk factors and incorporate uncertainty intervals into these estimates. Overall, 38 % of the documented stroke burden was due to high blood pressure (12 % males; 26 % females). This translated to 520 YLL per year (95 % CI: 325-678) and 540 DALYs (CI: 343-717). Excess Body Mass Index (BMI) was calculated as responsible for 20 % of the stroke burden (3.5 % males; 16 % females). This translated to 260 YLLs (CI: 199-330) and 277 DALYs (CI: 211-350). Burden was disproportionately higher in young females when BMI was assessed. High blood pressure and excess weight, which both have effective interventions, are responsible for a significant proportion of the stroke burden in rural SA; the burden varies across age and sex sub-groups. The most effective way forward to reduce the stroke burden requires both population wide policies that have an impact across the age spectra and targeted (health promotion/disease prevention) interventions on women and young people.

To determine the effect of medication burden on persistent use of newly added lipid-lowering (LL) drugs among patients with hypertension. This retrospective database study used medical and pharmacy claims from a mid-Atlantic managed care organization. The cohort was obtained from continuous member enrollment in pharmacy and medical benefits from January 1, 2003, to December 31, 2005. Prescription claims were obtained for 18 months following the date of the first filled LL prescription (ie, index date). Patients were stratified into patients who changed LL drug or strength (group 1) and patients who did not change LL drug or strength (group 2). The primary outcome measure was persistence to newly added LL therapy. Persistence was defined by the length of time a member remained on therapy following the index date. The secondary outcome measure was the medication possession ratio (MPR). The MPR was calculated as the ratio of the sum of the days' supply of prescription filled divided by the number of days filled, plus the days' supply for the final prescription fill. Associations between the daily medication burden, defined as the number of unique drug products, and the outcome measures were analyzed. In the cohort of 3058 patients, the mean medication burden was 2.9 medications. Medication burden was positively associated with persistence and MPR through 18 months. Patients who had greater medication burden had longer persistence (P <.001). Likewise, patients who had greater medication burden had higher MPRs and were more likely to be considered adherent (MPR, >80%) (P < .001 for both). Patients with higher medication burden had greater adherence to newly added LL therapy. Medication burden should not deter clinicians from adding LL therapy. Among patients with added LL therapy, more attention should focus on patients who have changes to their LL regimen compared with patients who continue on the same LL prescription.

Forecasting the burden of future postmenopausal hip fractures.

A growing elderly population is expected worldwide, and the rate of hip fractures is decisive for the future fracture burden. Significant declines in hip fracture rates in Norway, the USA, France, Germany, and the UK are required to counteract the impact of the ageing effects. This study aims to evaluate the consequences of the expected growth of the elderly population worldwide on the hip fracture burden using Norway as an example. Furthermore, we wanted to estimate the decline in hip fracture rates required to counteract the anticipated increase in the burden of hip fracture for Norway, the USA, France, Germany, and the UK. The burden of future postmenopausal hip fractures in Norway were estimated given (1) constant age-specific rates, (2) continued decline, and (3) different cohort scenarios. Based on population projection estimates and population age-specific hip fracture rates in women 65 years and older, we calculated the required declines in hip fracture rates needed to counteract the growing elderly populations in Norway, the USA, France, Germany, and the UK. The level of age-specific hip fracture rates had a huge impact on the future hip fracture burden in Norway. Even if the hip fracture rates decline at the same speed, a 22 % increase in the burden of hip fractures can be expected by 2040. An annual decline in hip fracture rates of 1.1-2.2 % until 2040 is required to counteract the effects of the growing elderly population on the future burden of hip fractures in Norway, the USA, France, Germany, and the UK. Hip fracture rates have a great impact on the burden of hip fractures. The rates will have to decline significantly to counteract the impact of a growing elderly population. A change in preventive strategies and further studies are warranted to identify the complex causes associated to hip fractures.

The current therapeutic arsenal for toxoplasmosis is restricted to drugs non-specific to the parasite which cause important side effects. Development of more efficient and specific anti-Toxoplasma compounds is urgently needed. Imidazo[1,2-b]pyridazines designed to inhibit the calcium-dependent protein kinase 1 of Toxoplasma gondii (TgCDPK1) and effective against tachyzoite growth in vitro at submicromolar ranges were modified into hydrochloride salts to be administered in vivo in a mouse model of acute toxoplasmosis. All protonated imidazo[1,2-b]pyridazine salts (SP230, SP231 and SP232) maintained their activity on TgCDPK1 and T. gondii tachyzoites. Rat and mouse liver microsomes were used to predict half-life and intrinsic clearance, and the pharmacokinetic profile of the most rapidly degraded imidazo[1,2b]pyridazine salt (SP230) was determined in serum, brain and lungs of mice after a single administration of 50 mg/kg. Compounds were then tested in vivo in a murine model of acute toxoplasmosis. Mice infected with tachyzoites of the ME49 strain of T. gondii were treated for 4, 7 or 8 days with 25 or 50 mg/kg/day of SP230, SP231 or SP232. The parasite burdens were strongly diminished (>90% reduction under some conditions) in the spleen and the lungs of mice treated with imidazo[1,2-b]pyridazine salts compared with untreated mice, without the need for pre-treatment. Moreover, no increases in the levels of hepatic and renal toxicity markers were observed, demonstrating no significant signs of short-term toxicity. To conclude, imidazo[1,2-b]pyridazine salts have strong efficacy in vivo on acute toxoplasmosis and should be further tested in a model of mouse congenital toxoplasmosis.

Hospital discharge planning for clients with schizophrenia reduces client rehospitalization rates and improves their medication adherence. The effectiveness of caregiver participation in hospital discharge planning has seldom been explored. The purpose of this study was to examine the effectiveness of caregiver participation in hospital discharge planning for clients with schizophrenia in reducing caregiver burden and improving health status. A quasi-experimental research design was adopted. The research location was in a psychiatric hospital in Northern Taiwan. The target population was caregivers of inpatients with schizophrenia. Nurses served as care coordinators and provided six-step hospital discharge planning services to caregivers. Structured questionnaires were employed to measure caregiver burden and health status. Intervention effect was tested using analysis of covariance in which outcome measure at pretest and selected demographic variables were treated as covariates. A total of 114 caregivers completed pretest and posttest evaluations, with 57 people in each group. A significant difference was found between the experimental and the control group regarding the caregiver burden and health status (P<0.001) The caregiver burden and health status of the experimental group improved more significantly compared with the control group. The caregiver-involved discharge planning process developed in this study effectively reduced the burden placed on caregivers and improved their health status. Mental health nurses can serve as the main care coordinators for assessment, planning, referral and provision of the required services. Caregiver-involved hospital discharge planning should become part of the routine care process. Copyright © 2017 Elsevier Inc. All rights reserved.

Pulmonary arterial hypertension (PAH), as a life-threatening disease with no efficient cure, may impose a tremendous economic burden on patients and healthcare systems. However, most existing studies have mainly emphasised epidemiology and medications, while large observational studies reporting on the economic burden are currently lacking. To review and evaluate evidence on the costs of PAH and the cost effectiveness of PAH treatments, and to summarise the corresponding cost drivers. Systematic literature searches were conducted in English-language databases (PubMed, Web of Science, ScienceDirect) and Chinese-language databases (China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP) to identify studies (published from 2000 to 2014) assessing the costs of PAH or the cost effectiveness of PAH treatments. The search results were independently reviewed and extracted by two reviewers. Costs were converted into 2014 US dollars. Of 1959 citations identified in the initial search, 19 papers were finally included in this analysis: eight on the economic burden of PAH and 11 on economic evaluation of PAH treatments. The economic burden on patients with PAH was rather large, with direct healthcare costs per patient per month varying from $2476 to $11,875, but none of the studies reported indirect costs. Sildenafil was universally reported to be a cost-effective treatment, with lower costs and better efficacy than other medications. Medical costs were reported to be the key cost drivers. The economic burden of patients with PAH is substantial, while the paucity of comprehensive country-specific evidence in this area and the lack of reports on indirect costs of PAH warrant researchers' concern, especially in China.

Breast cancer (BC) is the most common cancer diagnosed in women and the second most common cancer overall, ranking as the fifth cause of death from cancer. The chronicity of the disease produces long-term physiological and psychological manifestations, which adversely affect the quality of life of the individual. The primary treatment while managing cancer presents with various debilitating side effects. With the recent advances in treatment techniques that have improved the survival rate, patients suffer from continuing posttreatment complications. Patients seem to cope well with the stress of treatment of BC and sustain a normal life; however, the deterioration in physical well-being makes the patient functionally inefficient. Exercise has been proven to be an effective, safe, and feasible tool in combating the adverse effects of treatment, prevents complications and decreases the risk of BC-specific mortality. This review briefly presents an overview of the burden of the disease and its management strategies. Owing to the heterogeneity of the population and the multitude of therapies they receive, the response of each patient to treatment is different and so is the magnitude of adverse effects. The review discusses the late sequelae following treatment and evidence supporting the role of physical activity in their management. In conclusion, there is a need for personalized physical activity plans to be developed to suit the individual and their circumstances. PMID:29376027

Relating drug–protein interaction network with drug side effects

Motivation: Identifying the emergence and underlying mechanisms of drug side effects is a challenging task in the drug development process. This underscores the importance of system–wide approaches for linking different scales of drug actions; namely drug-protein interactions (molecular scale) and side effects (phenotypic scale) toward side effect prediction for uncharacterized drugs. Results: We performed a large-scale analysis to extract correlated sets of targeted proteins and side effects, based on the co-occurrence of drugs in protein-binding profiles and side effect profiles, using sparse canonical correlation analysis. The analysis of 658 drugs with the two profiles for 1368 proteins and 1339 side effects led to the extraction of 80 correlated sets. Enrichment analyses using KEGG and Gene Ontology showed that most of the correlated sets were significantly enriched with proteins that are involved in the same biological pathways, even if their molecular functions are different. This allowed for a biologically relevant interpretation regarding the relationship between drug–targeted proteins and side effects. The extracted side effects can be regarded as possible phenotypic outcomes by drugs targeting the proteins that appear in the same correlated set. The proposed method is expected to be useful for predicting potential side effects of new drug candidate compounds based on their protein-binding profiles.

Variations in judgments of intentional action and moral evaluation across eight cultures.

Robbins, Erin; Shepard, Jason; Rochat, Philippe

Individuals tend to judge bad side effects as more intentional than good side effects (the Knobe or side-effect effect). Here, we assessed how widespread these findings are by testing eleven adult cohorts of eight highly contrasted cultures on their attributions of intentional action as well as ratings of blame and praise. We found limited generalizability of the original side-effect effect, and even a reversal of the effect in two rural, traditional cultures (Samoa and Vanuatu) where participants were more likely to judge the good side effect as intentional. Three follow-up experiments indicate that this reversal of the side-effect effect is not due to semantics and may be linked to the perception of the status of the protagonist. These results highlight the importance of factoring cultural context in our understanding of moral cognition. Copyright © 2017. Published by Elsevier B.V.

The introduction of topical steroids (TS) of varying potency have rendered the therapy of inflammatory cutaneous disorders more effective and less time-consuming. However the usefulness of these has become a double edged sword with constantly rising instances of abuse and misuse leading to serious local, systemic and psychological side effects. These side effects occur more with TS of higher potency and on particular areas of the body like face and genitalia. The article reviews the side effects of TS with special mention about peadiatric age group, also includes the measures for preventing the side effects.

Family caregiver burden in mental illnesses: The case of affective disorders and schizophrenia - a qualitative exploratory study.

Caregivers of people with mental illnesses often experience a wide range of burdens. Although many studies have confirmed burdens among family caregivers of mentally ill relatives in general, specific knowledge regarding the concrete everyday hassle and existential sorrows from the caregiverś subjective reasoning perspective is lacking. Furthermore, there is little evidence on the possible different effects of affective disorders and schizophrenia on the quality of burden; this is also true with regard to the role of cultural traditions and lay beliefs. The aim of this study was to explore the specific burdens experienced by caregivers of patients with schizophrenia and affective disorders. A qualitative study was conducted by semi-structured interviews with 45 caregivers of patients with schizophrenia and affective disorders. Data were analysed by qualitative content analysis. Eleven encumbering themes resulted from the interviews including incertitude, unawareness, emotional burden, stigma and blame, financial burden, physical burden, restriction in routine, disruption in routine, dissatisfaction with family, relatives, and acquaintances, troubles with patients' adherence to medication, and problems with health services and governmental support. Caring for a person with mental illness affects caregivers emotionally, financially, physically, and it elicits some restrictions in their routine (daily hassles). Finally, it causes conflicts in family relationships. Despite some differences regarding perceived burden among caregivers of schizophrenia and affective disorders, a common pattern of burden could be identified. Thus, authorities should provide adequate financial, educational, and psychosocial supports for caregivers of mental illnesses.

Besides the description of the sample-including their burden level-, a contrast mean was used to identify characteristics that influenced in punctuation of Zarit scale. A logistic regression was used to analyse characteristics that increase the likelihood to experiment burden. 61.9% of caregivers are subject to intense burden. The item on the scale which contributes most to the caregiver burden is the lack of time for oneself, followed by the negative effects of interpersonal relationships. Contrast means shows that degree of relationship, number of care hours, caregiver health and aggressiveness of dependent persons produce significant differences in Zarit scale. Physic and psychological health of caregivers and aggressiveness of dependent persons is associated with the likelihood of developing caregiver burden. Informal caregivers of dependent persons show a high level of burden, both related to their characteristics and those of the dependent persons. Caregiver burden rethinks the need for public policies focused on dependence to adopt an integrative caregiver-dependent vision. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Effectiveness and side-effect profile data on pharmacotherapy for daytime sleepiness in central hypersomnias are based largely upon randomized controlled trials. Evidence regarding the use of combination therapy is scant. The aim of this study was to examine the effectiveness and occurrence of drug-related side effects of these drugs in routine clinical practice. Adult patients diagnosed with a central hypersomnia during a 54-month period at a tertiary sleep disorders centre were identified retrospectively. Side effects were recorded at every follow-up visit. A total of 126 patients, with 3275 patient-months of drug exposure, were categorized into narcolepsy type 1 (n = 70), narcolepsy type 2 (n = 47) and idiopathic hypersomnia (n = 9). Modafinil was the most common drug used as a first-line treatment (93%) and in combination therapy (70%). Thirty-nine per cent of the patients demonstrated a complete, 25% partial and 36% a poor response to treatment. Combination treatment improved daytime sleepiness in 55% of the patients with residual symptoms despite monotherapy. Sixty per cent of patients reported side effects, and 30% reported treatment-limiting side effects. Drugs had similar side-effect incidence (P = 0.363) and their side-effect profile met those reported in the literature. Twenty-seven per cent of the patients received combination treatment and had fewer side effects compared to monotherapy (29.4% versus 60%, respectively, P = 0.001). Monotherapy appears to achieve satisfactory symptom control in most patients with central hypersomnia, but significant side effects are common. Combination therapy appears to be a useful and safe option in patients with refractory symptoms. © 2017 European Sleep Research Society.

The economic cost is measured on direct and indirect medical costs, which vary depending on stage at diagnosis, patient age, type of medical services, and site of service. Costs vary by region, physician behavior, and patient preferences. When analyzing the economic burden of survivors of colon cancer, we cannot forget the societal burden. Post-acute care and readmissions are major economic burdens. People with colon cancer have to be followed for their lifetime. Economic models are being studied to give cost-effective solutions to this problem. Copyright © 2017 Elsevier Inc. All rights reserved.

A new class of diphenylurea was identified as a novel antibacterial scaffold with an antibacterial spectrum that includes highly resistant staphylococcal isolates, namely methicillin- and vancomycin-resistant Staphylococcus aureus (MRSA & VRSA). Starting with a lead compound 3 that carries an aminoguanidine functionality from one side and a n-butyl moiety on the other ring, several analogues were prepared. Considering the pharmacokinetic parameters as a key factor in structural optimization, the structure-activity-relationships (SARs) at the lipophilic side chain were rigorously examined leading to the discovery of the cycloheptyloxyl analogue 21n as a potential drug-candidate. This compound has several notable advantages over vancomycin and linezolid including rapid killing kinetics against MRSA and the ability to target and reduce the burden of MRSA harboring inside immune cells (macrophages). Furthermore, the potent anti-MRSA activity of 21n was confirmed in vivo using a Caenorhabditis elegans animal model. The present study provides a foundation for further development of diphenylurea compounds as potential therapeutic agents to address the burgeoning challenge of bacterial resistance to antibiotics.

The burden of non-communicable diseases (NCDs) has increased in sub-Saharan countries, including Ethiopia. The contribution of dietary behaviours to the NCD burden in Ethiopia has not been evaluated. This study, therefore, aimed to assess diet-related burden of disease in Ethiopia between 1990 and 2013. We used the 2013 Global Burden of Disease (GBD) data to estimate deaths, years of life lost (YLLs) and disability-adjusted life years (DALYs) related to eight food types, five nutrients and fibre intake. Dietary exposure was estimated using a Bayesian hierarchical meta-regression. The effect size of each diet-disease pair was obtained based on meta-analyses of prospective observational studies and randomized controlled trials. A comparative risk assessment approach was used to quantify the proportion of NCD burden associated with dietary risk factors. In 2013, dietary factors were responsible for 60,402 deaths (95% Uncertainty Interval [UI]: 44,943-74,898) in Ethiopia-almost a quarter (23.0%) of all NCD deaths. Nearly nine in every ten diet-related deaths (88.0%) were from cardiovascular diseases (CVD) and 44.0% of all CVD deaths were related to poor diet. Suboptimal diet accounted for 1,353,407 DALYs (95% UI: 1,010,433-1,672,828) and 1,291,703 YLLs (95% UI: 961,915-1,599,985). Low intake of fruits and vegetables and high intake of sodium were the most important dietary factors. The proportion of NCD deaths associated with low fruit consumption slightly increased (11.3% in 1990 and 11.9% in 2013). In these years, the rate of burden of disease related to poor diet slightly decreased; however, their contribution to NCDs remained stable. Dietary behaviour contributes significantly to the NCD burden in Ethiopia. Intakes of diet low in fruits and vegetables and high in sodium are the leading dietary risks. To effectively mitigate the oncoming NCD burden in Ethiopia, multisectoral interventions are required; and nutrition policies and dietary guidelines should be developed.

Management of recurrent cervical cancer by reirradiation after radiation treatment remains controversial. In Indonesia, there is currently no data about reirradiation tumor response and side effects. This study aims to assess the tumor response to and side effects of reirradiation, the effect of time interval between first radiation treatment and cancer recurrence on the tumor response and side effects, and the effect of tumor size on tumor response. A cohort retrospective study with no comparison was done with the Radiotherapy Department at Cipto Mangunkusumo General Hospital, Jakarta. Participants were recurrent cervical cancer patients undergoing reirradiation. Data was collected from patients’ medical records and follow-up phone calls. Twenty-two patients participated in this study. Nine patients (40.9%) had complete responses, 10 patients (45.5%) had partial responses, 1 patient (4.5%) had a stable response, and 2 patients (9.1%) had tumor progressions. In general, 15 patients (68.2%) had no to light side effects (grade 0-2 RTOG) and 7 patients (31.8%) had severe side effects (grade 3-4 RTOG). Four patients (18.1%) had severe gastrointestinal acute side effects, 6 patients (27.3%) had severe gastrointestinal late side effects, 2 patients (9.1%) had severe urogenital side effects, and there were no patients had severe urogenital late side effects. There was no significant difference in tumor response between patients with time interval between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was no significant difference in tumor response between patients with tumor size ≤4 cm vs. >4 cm. Reirradiation can be considered as a modality in recurrent cervical cancer management since good tumor response was achieved and the majority of patients had no to light side effects (grade 0-2 RTOG). This study found no correlation between tumor response, side effects, and time gap between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was also no correlation between tumor response and tumor size of ≤4 cm vs. > 4 cm.

There is a lack of studies of the size of burden associated with informal care giving in psychosis. To evaluate the objective and subjective burden of informal care giving to patients with psychoses, and to compare a diary and recall method for assessments of objective burden. Patients and their informal caregivers were recruited from nine Swedish psychiatric outpatient centres. Subjective burden was assessed at inclusion using the CarerQoL and COPE index scales. The objective burden (time and money spent) was assessed by the caregivers daily using diaries over four weeks and by recall at the end of weeks 1 and 2. One-hundred and seven patients (53% females; mean age 43 ± 11) and 118 informal caregivers (67%; 58 ± 15 years) were recruited. Informal caregivers spent 22.5 hours/week and about 14% of their gross income on care-related activities. The time spent was underestimated by two to 20 hours when assessed by recall than by daily diary records. The most prominent aspects of the subjective burden were mental problems. Despite a substantial amount of time and money spent on care giving, the informal caregivers perceived the mental aspects of burden as the most troublesome. The informal caregiver burden is considerable and should be taken into account when evaluating effects of health care provided to patients with psychoses.

[Purpose] Quality of life (QoL) can be closely related to caregiver burden, which may be a potential mediating effect on the relationships among stroke patient caregivers. This study investigated the predictors of caregiver's QoL based on patient and caregiver characteristics, with caregiver burden as a mediator. [Methods] This study was conducted using surveys, a literature review, and interviews. Survey data were collected from 238 subjects, who were diagnosed with stroke, and their family caregivers from October 2013 to April 2014. [Results] Caregiver health status, income, spouses caring for patients, and duration of hospitalization were identified as significant predictors of caregivers' QoL with a mediating effect of caregiver burden. The time spent on caregiving per day and patient education level were the only direct predictors of caregivers' QoL. [Conclusion] The responsibility of caring for patients with stroke, in particular for a spouse, must be administered by means of a holistic family-centered rehabilitation program. In addition, financial support and availability of various health and social service programs must be comprehensively provided in order to maintain caregivers' well-being.

The objective of this study was to estimate the prevalence of possible oral corticosteroid (OCS)-related side effects and health care resource use and costs in patients with asthma. This was a cross-sectional, matched-cohort, retrospective study using a commercial claims database. Adults with asthma diagnosis codes and evidence of asthma medication use were studied. Patients with high OCS use (≥30 days of OCS annually) were divided into those who did versus those who did not experience OCS-related possible side effects. Their health care resource use and costs were compared using linear regression or negative binomial regression models, adjusting for age, sex, geographic region, Charlson Comorbidity Index score, and chronic obstructive pulmonary disease status. After adjustment, high OCS users with possible side effects were more likely to have office visits (23.0 vs 19.6; P <0.001) and hospitalizations (0.44 vs 0.22; P <0.001) than those without possible side effects. Emergency department visits were similar between the groups. High OCS users with possible side effects had higher adjusted total annual mean health care costs ($25,168) than those without such side effects ($21,882; P =0.009). Among high OCS users, patients with possible OCS-related side effects are more likely to use health care services than those without such side effects. Although OCS may help control asthma and manage exacerbations, OCS side effects may result in additional health care resource use and costs, highlighting the need for OCS-sparing asthma therapies.

The current study aimed to untangle the mixed effects of language brokering by examining a contextual factor (i.e., parent-child alienation) and a personal attribute (i.e., resilience) that may relate to adolescents’ feelings during translating (i.e., sense of burden and efficacy) and that may moderate the association between such feelings and adolescent depressive symptoms. Participants included 557 adolescent language brokers (Mage = 12.96) in Mexican-American families. Results showed that adolescents with a strong sense of alienation from parents or low resilience a) experienced more burden or less efficacy in translating, and b) were more susceptible to the detrimental effects of feeling a sense of burden and the beneficial effects of experiencing a sense of efficacy, as measured by depressive symptoms.

Current treatment for HCV infections consists of approved direct acting antivirals (DAAs), viz. the protease inhibitors (boceprevir, telaprevir, and simeprevir), NS5B polymerase inhibitors (sofosbuvir) and NS5A inhibitor (ledipasvir) in combination with pegylated interferon α and ribavirin). These treatments have made a great improvement in the treatment of chronic HCV infections in recent years, but their adverse side effects, emergence of resistant mutants, high cost, and increased pill burden have limited their clinical use. Recently, with the increasing knowledge in understanding the HCV life cycle, more targets have been recognized. NS5A protein plays a critical role in assembly of infectious HCV particles and offering potential for HCV therapies. Therefore, discovery and development of novel DAAs targeting NS5A with novel mechanisms of action, is of great necessity to improve the quality of existing HCV treatments. In the present review, we discuss recent advances with NS5A inhibitors with potent anti-HCV activity, and the potential for the development of HCV NS5A inhibitors to combat HCV infections.

Lymphatic filariasis is a parasitic infection that causes a devastating public health and socioeconomic burden with an estimated infection of over 120 million individuals worldwide. The infection is caused by three closely related nematode parasites, namely, Wuchereria bancrofti, Brugia malayi, and B. timori, which are transmitted to human through mosquitoes of Anopheles, Culex, and Aedes genera. The species have many ecological variants and are diversified in terms of their genetic fingerprint. The rapid spread of the disease and the genetic diversification cause the lymphatic filarial parasites to respond differently to diagnostic and therapeutic interventions. This in turn prompts the current challenge encountered in its management. Furthermore, most of the chemical medications used are characterized by adverse side effects. These complications urgently warrant intense prospecting on bio-chemicals that have potent efficacy against either the filarial worms or thier vector. In lieu of this, we presented a review on recent literature that reported the efficacy of filaricidal biochemicals and those employed as vector control agents. In addition, methods used for biochemical extraction, screening procedures, and structure of the bioactive compounds were also presented. PMID:24298292

Review of Heterotopic Thyroid Autotransplantation

Total thyroidectomy is increasingly accepted for the management of bilateral benign thyroid disorders. Postoperatively, patients require lifelong levothyroxine replacement therapy to avoid postoperative hypothyroidism, which besides the burden of compliance, has been proven to be associated with several long-term side effects. Heterotopic thyroid autotransplantation was proposed several decades ago to avoid the need for life-long postoperative replacement therapy with maintaining the autoregulatory mechanism of thyroxin production inside the body according to its needs. Available data regarding this topic in literature is relatively poor. Before applying thyroid autotransplantation on humans, several studies have been done on animals, where the autologous transplantations were found to be successful in almost all the cases, proved by follow up postoperative 8-week measurements of thyroid hormones and histopathological examination of the removed autografts. Regarding the clinical application, few trials have been done using cryopreserved in vivo, in vitro or immediately autotransplanted thyroid autografts. Satisfactory results were obtained, however, the number of these studies and the number of patients per each study was very low. Besides the study methodologies were not so consistent. PMID:28535579

We analyze the issue of agency costs in aviation security by combining results from a quantitative economic model with a qualitative study based on semi-structured interviews. Our model extends previous principal-agent models by combining the traditional fixed and varying monetary responses to physical and cognitive effort with nonmonetary welfare and potentially transferable value of employees' own human capital. To provide empirical evidence for the tradeoffs identified in the quantitative model, we have undertaken an extensive interview process with regulators, airport managers, security personnel, and those tasked with training security personnel from an airport operating in a relatively high-risk state, Turkey. Our results indicate that the effectiveness of additional training depends on the mix of "transferable skills" and "emotional" buy-in of the security agents. Principals need to identify on which side of a critical tipping point their agents are to ensure that additional training, with attached expectations of the burden of work, aligns the incentives of employees with the principals' own objectives. © 2016 Society for Risk Analysis.

Pharmacotherapy of anxiety disorders: a critical review

Given the enormous contribution of anxiety disorders to the burden of disease, it is key to optimize their prevention and treatment. In this critical review we assess advances in the pharmacotherapy of anxiety disorders, as well as remaining challenges, in recent decades, the field has seen rigorous clinical trial methods to quantify the efficacy and safety of serendipitously discovered agents, more focused development of medications with selective mechanisms of action, and the gradual translation of insights from laboratory research into proof-of-principle clinical trials. On the positive side, a considerable database of studies shows efficacy and relative tolerability of the selective serotonin reuptake inhibitors in the major anxiety disorders, and secondary analyses of such datasets have informed questions such as optimal definition of response and remission, optimal dose and duration, and comparative efficacy of different agents. Significant challenges in the field include barriers to appropriate diagnosis and treatment of anxiety disorders, failure of a significant proportion of patients to respond to first-line pharmacotherapy agents, and a limited database of efficacy or effectiveness studies to guide treatment in such cases.

Hepatitis C virus (HCV) affects approximately 268,000 Canadians and results in more years of life lost than any other infectious disease in the country. Both the Canadian Institutes of Health Research (CIHR) and the Public Health Agency of Canada (PHAC) have identified HCV-related liver disease as a priority and supported the establishment of a National Hepatitis C Research Network. In 2015, the introduction of new interferon- (IFN-) free therapies with high cure rates (>90%) and few side effects revolutionized HCV therapy. However, a considerable proportion of the population remains undiagnosed and treatment uptake remains low in Canada due to financial, geographical, cultural, and social barriers. Comprehensive prevention strategies, including enhanced harm reduction, broader screening, widespread treatment, and vaccine development, are far from being realized. The theme of the 2016 symposium, “We're not done yet: remaining challenges in Hepatitis C,” was focused on identifying strategies to enhance prevention, diagnosis, and treatment of HCV to reduce disease burden and ultimately eliminate HCV in Canada.

Pentavalent antimonial has been the first choice treatment for visceral leishmaniasis; however, it has several side effects that leads to low adherence to treatment. Liposome-encapsulated meglumine antimoniate (MA) arises as an important strategy for chemotherapy enhancement. We evaluated the immunopathological changes using the mixture of conventional and pegylated liposomes with MA. The mice were infected with Leishmania infantum and a single-dose treatment regimen. Comparison was made with groups treated with saline, empty liposomes, free MA, and a liposomal formulation of MA (Lipo MA). Histopathological analyses demonstrated that animals treated with Lipo MA showed a significant decrease in the inflammatory process and the absence of granulomas. The in vitro stimulation of splenocytes showed a significant increase of gamma interferon (IFN-γ) produced by CD8 + T cells and a decrease in interleukin-10 (IL-10) produced by CD4 + and CD8 + T cells in the Lipo MA. Furthermore, the Lipo MA group showed an increase in the IFN-γ/IL-10 ratio in both CD4 + and CD8 + T cell subsets. According to the parasite load evaluation using quantitative PCR, the Lipo MA group showed no L. infantum DNA in the spleen (0.0%) and 41.4% in the liver. In addition, we detected a low positive correlation between parasitism and histopathology findings (inflammatory process and granuloma formation). Thus, our results confirmed that Lipo MA is a promising antileishmanial formulation able to reduce the inflammatory response and induce a type 1 immune response, accompanied by a significant reduction of the parasite burden into hepatic and splenic compartments in treated animals.

Although tuberculosis is a major cause of morbidity and mortality worldwide, available funding falls far short of that required for effective control. Economic and spillover consequences of investments in the treatment of tuberculosis are unclear, particularly when steep gradients in the disease and response are linked by population movements, such as that between Papua New Guinea (PNG) and the Australian cross-border region. To undertake an economic evaluation of Australian support for the expansion of basic Directly Observed Treatment, Short Course in the PNG border area of the South Fly from the current level of 14% coverage. Both cost-utility analysis and cost-benefit analysis were applied to models that allow for population movement across regions with different characteristics of tuberculosis burden, transmission, and access to treatment. Cost-benefit data were drawn primarily from estimates published by the World Health Organization, and disease transmission data were drawn from a previously published model. Investing $16 million to increase basic Directly Observed Treatment, Short Course coverage in the South Fly generates a net present value of roughly $74 million for Australia (discounted 2005 dollars). The cost per disability-adjusted life-year averted and quality-adjusted life-year saved for PNG is $7 and $4.6, respectively. Where regions with major disparities in tuberculosis burden and health system resourcing are connected through population movements, investments in tuberculosis control are of mutual benefit, resulting in net health and economic gains on both sides of the border. These findings are likely to inform the case for appropriate investment in tuberculosis control globally. Copyright © 2015 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

To compare pre- and post-operative shoulder active range of motion (AROM) values from female breast cancer survivors to population norm values for shoulder AROM; and to compare shoulder AROM differences pre- and post-surgery between female African American and White breast cancer survivors (BCA). This pilot study used a convenience sample and longitudinal design measuring participants 2 times (T0 = baseline, after biopsy but within 2 weeks before BCA surgery; T1 = 2 nd postoperative week). The U.S. has the largest BCA survivor population in history and yet the mortality burden remains highest among AA BCA survivors. AAs may also have greater burden of physical and functional side effects compared to whites and the general population. The data were collected from a convenience sample (n = 33; n AA = 9, n W = 24) and included data on shoulder AROM, medical chart review for pre- and co-morbid conditions, and self-reported demographics and medical history. We used t-tests to compare sample AROM means to population norms. We then compared our sample across 2 timepoints (T0 = pre-surgery; T1 = 2 weeks post-surgery) using independent samples t-tests and repeated measures analysis of variance (p < .05) to compare AA to White sub-samples AROM means. African Americans had significantly less shoulder abduction (at T0) and flexion (at T1) than whites. However, 100% had significantly reduced AROM for all movements at T0 (prior to surgery but after biopsy) when compared to population norms. The significant reduction in shoulder AROM after biopsy but before surgery points to a possible unmet need for early physical therapy intervention. Further research using randomized controlled trial design is recommended.

Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an active pharmaceutical ingredient (API) when immediate-release as well as extended-release formulations were on the market together (fourth quarter of 2011 to second quarter of 2016). Tapentadol (API) was compared with tramadol, hydrocodone, morphine, oxycodone, hydromorphone, and oxymorphone across Poison Center, Drug Diversion, and Treatment Center Programs Combined data streams from the Researched Abuse, Diversion and Addiction-Related Surveillance system. Findings suggest the public health burden related to tapentadol to date is low, but present. Event rates of abuse per population-level denominators were significantly lower than all other opioids examined. However, when adjusted for drug availability, event rates of abuse were lower than most Schedule II opioids studied, but were not the lowest. Disentangling these 2 sets of findings further by examining various opioid formulations, such as extended-release and the role of abuse-deterrent formulations, is warranted. This article presents the results from an examination of tapentadol API across the Researched Abuse, Diversion and Addiction-Related Surveillance System: a broad and carefully designed postmarketing mosaic. Data to date from Poison Center, Drug Diversion, and Treatment Centers combined suggest a low, but present public health burden related to tapentadol. Copyright © 2018. Published by Elsevier Inc.

Background Neuropathic pain following surgical treatment for breast cancer with or without chemotherapy is a clinical burden and patients frequently report cognitive, emotional and quality of life impairment. A preclinical study recently showed that memantine administered before surgery may prevent neuropathic pain development and cognitive dysfunction. With a translational approach, a clinical trial has been carried out to evaluate whether memantine administered before and after mastectomy could prevent the development of neuropathic pain, the impairment of cognition and quality of life. Method A randomized, pilot clinical trial included 40 women undergoing mastectomy in the Oncology Department, University Hospital, Clermont-Ferrand, France. Memantine (5 to 20 mg/day; n = 20) or placebo (n = 20) was administered for four weeks starting two weeks before surgery. The primary endpoint was pain intensity measured on a (0–10) numerical rating scale at three months post-mastectomy. Results Data analyses were performed using mixed models and the tests were two-sided, with a type I error set at α = 0.05. Compared with placebo, patients receiving memantine showed at three months a significant difference in post-mastectomy pain intensity, less rescue analgesia and a better emotional state. An improvement of pain symptoms induced by cancer chemotherapy was also reported. Conclusions This study shows for the first time the beneficial effect of memantine to prevent post-mastectomy pain development and to diminish chemotherapy-induced pain symptoms. The lesser analgesic consumption and better well-being of patients for at least six months after treatment suggests that memantine could be an interesting therapeutic option to diminish the burden of breast cancer therapy.

Antipsychotic medications often have a variety of side effects, however, it is not well understood how the presence of specific side effects correlate with adherence in a real-world setting. The aim of the current study was to examine the relationship between these variables among community-dwelling patients with schizophrenia. Data were analyzed from a 2007-2008 nationwide survey of adults who self-reported a diagnosis of schizophrenia and were currently using an antipsychotic medication (N = 876). The presence of side effects was defined as those in which the patient reported they were at least "somewhat bothered". Adherence was defined as a score of zero on the Morisky Medication Adherence Scale. To assess the relationship between side effects and adherence, individual logistic regression models were fitted for each side effect controlling for patient characteristics. A single logistic regression model assessed the relationship between side effect clusters and adherence. The relationships between adherence and health resource use were also examined. A majority of patients reported experiencing at least one side effect due to their medication (86.19%). Only 42.5% reported complete adherence. Most side effects were associated with a significantly reduced likelihood of adherence. When grouped as side effect clusters in a single model, extra pyramidal symptoms (EPS)/agitation (odds ratio (OR) = 0.57, p = 0.0007), sedation/cognition (OR = 0.70, p = 0.033), prolactin/endocrine (OR = 0.69, p = 0.0342), and metabolic side effects (OR = 0.64, p = 0.0079) were all significantly related with lower rates of adherence. Those who reported complete adherence to their medication were significantly less likely to report a hospitalization for a mental health reason (OR = 0.51, p = 0.0006), a hospitalization for a non-mental health reason (OR = 0.43, p = 0.0002), and an emergency room (ER) visit for a mental health reason (OR = 0.60, p = 0.008). Among patients with schizophrenia, medication side effects are highly prevalent and significantly associated with medication nonadherence. Nonadherence is significantly associated with increased healthcare resource use. Prevention, identification, and effective management of medication-induced side effects are important to maximize adherence and reduce health resource use in schizophrenia.

A patient perspective of the impact of medication side effects on adherence: results of a cross-sectional nationwide survey of patients with schizophrenia

PubMed Central

2012-01-01

Background Antipsychotic medications often have a variety of side effects, however, it is not well understood how the presence of specific side effects correlate with adherence in a real-world setting. The aim of the current study was to examine the relationship between these variables among community-dwelling patients with schizophrenia. Methods Data were analyzed from a 2007-2008 nationwide survey of adults who self-reported a diagnosis of schizophrenia and were currently using an antipsychotic medication (N = 876). The presence of side effects was defined as those in which the patient reported they were at least "somewhat bothered". Adherence was defined as a score of zero on the Morisky Medication Adherence Scale. To assess the relationship between side effects and adherence, individual logistic regression models were fitted for each side effect controlling for patient characteristics. A single logistic regression model assessed the relationship between side effect clusters and adherence. The relationships between adherence and health resource use were also examined. Results A majority of patients reported experiencing at least one side effect due to their medication (86.19%). Only 42.5% reported complete adherence. Most side effects were associated with a significantly reduced likelihood of adherence. When grouped as side effect clusters in a single model, extra pyramidal symptoms (EPS)/agitation (odds ratio (OR) = 0.57, p = 0.0007), sedation/cognition (OR = 0.70, p = 0.033), prolactin/endocrine (OR = 0.69, p = 0.0342), and metabolic side effects (OR = 0.64, p = 0.0079) were all significantly related with lower rates of adherence. Those who reported complete adherence to their medication were significantly less likely to report a hospitalization for a mental health reason (OR = 0.51, p = 0.0006), a hospitalization for a non-mental health reason (OR = 0.43, p = 0.0002), and an emergency room (ER) visit for a mental health reason (OR = 0.60, p = 0.008). Conclusions Among patients with schizophrenia, medication side effects are highly prevalent and significantly associated with medication nonadherence.

Development of a New Self-Reporting Instrument Measuring Benefits and Side Effects of Corticosteroids in Duchenne Muscular Dystrophy: Report from a Pilot Study.

PubMed

Hendriksen, Ruben G F; Lionarons, Judith M; Hendriksen, Jos G M; Vles, Johan S H; McAdam, Laura C; Biggar, W Douglas

There is no cure for Duchenne Muscular Dystrophy (DMD); treatment is symptomatic and corticosteroids slow the progression. Side effects of corticosteroids - especially the physical effects - have been described, however patients' and caregivers perception on chronic corticosteroid treatment and their side effects is less well known, in particular with regards to cognition, behaviour, and emotional functioning. The primary aim of this pilot study was to (i) construct a self-report questionnaire to assess the perceived benefits and side effects of corticosteroids for patients with DMD and their parents. Furthermore we aimed to (ii) investigate the psychometric qualities of this questionnaire, (iii) whether there was a difference between parents' and patient's perceptions, and finally (iv) to what extent reported side effects may alter over time. A 23-item questionnaire (SIDECORT: side effect of corticosteroids) was constructed to assess the perception of these benefits and side effects in a systematic manner. In total, 86 patients (aged 5 - 28 years) and 125 of their parents completed the questionnaire. Internal consistency was good. Using factor analyses on the side effect items as reported by parents, two underlying factors were found, with the first factor describing cognitive, behavioural and emotional functioning, and the second factor describing physical functioning. The potential benefits of corticosteroids were highly rated among both parents and patients, although parents rated the importance of the benefits higher than their sons (p = 0.002). Similarly, parents rated the severity of the side effects generally higher than their sons (p = 0.011), especially with regards to the physical side effects (p = 0.014). Based on the parent's perception, the neurodevelopmental side effects generally appeared to decline the longer corticosteroids were used. To our knowledge, this is the first explicit study on perceived cognitive-, behavioural-, and emotional side effects and the allocation of benefits to corticosteroids in DMD. On the basis of our research we suggest a short form questionnaire, which proves to be reliable and valid for research- and clinical practice. This questionnaire could provide useful insights for the care of boys and men with DMD.

Central nervous system side effects associated with zolpidem treatment.

PubMed

Toner, L C; Tsambiras, B M; Catalano, G; Catalano, M C; Cooper, D S

2000-01-01

Zolpidem is one of the newer medications developed for the treatment of insomnia. It is an imidazopyridine agent that is an alternative to the typical sedative-hypnotic agents. Zolpidem use is gaining favor because of its efficacy and its side effect profile, which is milder and less problematic than that of the benzodiazepines and barbiturates used to treat insomnia. Still, side effects are not uncommon with zolpidem use. We report a series of cases in which the patients developed delirium, nightmares and hallucinations during treatment with zolpidem. We will review its pharmacology, discuss previous reports of central nervous system side effects, examine the impact of drug interactions with concurrent use of antidepressants, examine gender differences in susceptibility to side effects, and explore the significance of protein binding in producing side effects.

"Side effects affected my daily activities a lot": a qualitative exploration of the impact of contraceptive side effects in Bangladesh.

2017-01-01

In a country like Bangladesh that has made great progress in contraceptive use with one of the lowest levels of fertility and highest levels of contraceptive use, understanding what factors influence women's decisions to discontinue a contraceptive method and not switch to a new method is critical in designing interventions and programs that will help enable Bangladesh to reach its FP2020 goals. Research on side effects has focused on physical manifestations like headaches, moodiness, abdominal pain, and menstrual irregularities. While physical effects alone may stop women from continuing a contraceptive method, less is known about how side effects influence women's daily activities and lives. The purpose of this study is to understand the ways that side effects affect Bangladeshi women's participation in different social settings. Thirty-five in-depth interviews with married women who recently discontinued or switched to a different contraceptive method were conducted in Sylhet and Khulna Divisions. Interviews explored reasons for discontinuation including experience of side effects and impact of side effects on women's lives. Key themes emerged including that side effects are not only experienced physically but are barriers to women's participation in many aspects of their lives. The spheres of life that most commonly appeared to be influenced by side effects include religion, household, and sexual intimacy irrespective of method used or residence. Family planning providers need to be aware of these additional consequences associated with contraceptive side effects to provide tailored counseling that recognizes these issues and helps women to mitigate them. For Bangladesh to achieve its FP2020 goals, understanding the broader context in which family planning decisions are made vis-à-vis side effects is critical to design programs and interventions that meet all the needs of women beyond just their fertility intentions.

Validity and reliability of Turkish Caregiver Burden Scale among family caregivers of haemodialysis patients.

2014-02-01

To investigate the validity and reliability of the Caregiver Burden Scale in family members who provide primary care for haemodialysis patients. In Turkey, there is a need for a multi-dimensional instrument to evaluate the caregiver burden in people who provide care for patients with chronic diseases. A methodological study. The study sample consisted of 161 family members who provide primary care for haemodialysis patients. The forward-backward translation method was used to develop the Turkish Caregiver Burden Scale. The reliability was based on internal consistency investigated by Cronbach's alpha and item-total correlation. The factorial construct validity of the scale was tested with confirmatory factor analysis. By means of convergent and divergent validity, correlation between Caregiver Burden Scale and 36-Item Short Form Health Survey (SF-36) and correlation between Caregiver Burden Scale and the Maslach Burnout Scale were investigated. Cronbach's alpha and item-total correlations results suggested that there was good internal reliability. We found five underlying factors similar to original Scale's five-factor solution. The confirmatory factor analysis five-factor model represented an acceptable fit. Factor loadings were significant, with standardised loadings ranging from 0·43-0·81. By means of divergent validity, all sub-dimension scores and the total score of the Caregiver Burden Scale were negatively correlated with the SF-36, whereas there was a positive correlation with the emotional exhaustion and depersonalisation subscales of the Maslach Burnout Scale as expected. These results suggest that the Caregiver Burden Scale is a reliable and valid instrument which can be used with confidence in Turkish caregivers for haemodialysis patients to screen caregiver burden. The burden experienced by people who provide care for patients with chronic diseases can be evaluated with the Caregiver Burden Scale. Additionally, the Caregiver Burden Scale can be used in the evaluation of the effectiveness of attempts to decrease caregiver burden. © 2012 Blackwell Publishing Ltd.

Caregiver Burden Among Caregivers of Individuals With Severe Mental Illness: Testing the Moderation and Mediation Models of Resilience.

PubMed

Mulud, Zamzaliza Abdul; McCarthy, Geraldine

2017-02-01

The association between the socio-demographic characteristics of caregivers, such as gender and caregiver burden, is well documented; however, the process underlying this relationship is poorly understood. Based on the stress process model, we designed a cross-sectional study to examine the mediating and moderating effect of resilience on the relationship between gender and caregiver burden. Caregivers of individuals with severe mental illness (n=201) were recruited in two psychiatric outpatient clinics in Malaysia. The relationship between the gender of the caregiver and caregiver burden was mediated by resilience, thus supporting the stress process model. The findings from the present research contribute to the growing evidence of the interaction between socio-demographic variables of caregivers and resilience, and caregiver burden.

Armstrong, Nicole; Schupf, Nicole; Grafman, Jordan; Huey, Edward D.

2015-01-01

Background and Aims Caregiver stress is often a serious problem when caring for a patient with frontal lobe dysfunction. Methods A total of 102 caregivers of both patients with frontotemporal degeneration and corticobasal syndrome completed the Frontal Systems Behavior Scale (FrSBe) and the Zarit Burden Interview (ZBI). To analyze the association between apathy or disinhibition (or both) and caregiver burden, the effects of the total FrSBe and the apathy and disinhibition subscales of the FrSBE on the total ZBI score were assessed with logistic regressions and t tests. Results Total FrSBE score and the apathy FrSBE subscore predicted caregiver burden. Apathy occurred without disinhibition, and the two occurred together, but disinhibition without apathy was very rare. Conclusions Disinhibition without apathy occurred very rarely. Apathy was more associated with caregiver burden than disinhibition. PMID:24022248

In deciding on the treatment plan for patients with chronic obstructive pulmonary disease (COPD), the burden of COPD as experienced by patients should be the core focus. It is therefore important for daily practice to develop a tool that can both assess the burden of COPD and facilitate communication with patients in clinical practice. This paper describes the development of an integrated tool to assess the burden of COPD in daily practice. A definition of the burden of COPD was formulated by a Dutch expert team. Interviews showed that patients and health-care providers agreed on this definition. We found no existing instruments that fully measured burden of disease according to this definition. However, the Clinical COPD Questionnaire meets most requirements, and was therefore used and adapted. The adapted questionnaire is called the Assessment of Burden of COPD (ABC) scale. In addition, the ABC tool was developed, of which the ABC scale is the core part. The ABC tool is a computer program with an algorithm that visualises outcomes and provides treatment advice. The next step in the development of the tool is to test the validity and effectiveness of both the ABC scale and tool in daily practice.

Families of Veterans with traumatic brain injury (TBI) are often faced with providing long-term informal care to their loved one. However, little is known about how their perceived health and caregiving burden contribute to their quality of life (QOL). The purpose of this descriptive study was to describe perceived health, somatic symptoms, caregiver burden, and perceived QOL and to identify the extent to which these variables are associated with QOL in female partners/spouses of Veterans with TBI. Participants completed a written questionnaire including the Patient Health Questionnaire-15, Caregiver Reaction Assessment, Quality of Life Index, and the general health subscale of the 12-Item Short Form Survey version 2. Caregivers reported moderate levels of QOL, and over a quarter of the sample reported high levels of somatic symptoms, particularly fatigue and sleep disturbance. Age, perceived general health, somatic symptoms, the five subscales of caregiver burden (self-esteem, disrupted schedule, effect on finances, lack of family support, and effect on health) predicted QOL and explained 64% of its variance (adjusted r 2 = 0.64, F(8,31) = 9.59). However, only somatic symptoms and the caregiver burden subscales of self-esteem and effect on finances were significant predictors in the model. These findings have implications for development of family-centered interventions to enhance the QOL of informal caregivers of Veterans with TBI.

Objective Non-communicable diseases (NCDs) are the biggest cause of death in Europe putting an unsustainable burden on already struggling health systems. Increases in obesity are a major cause of NCDs. This paper projects the future burden of coronary heart disease (CHD), stroke, type 2 diabetes and seven cancers by 2030 in 53 WHO European Region countries based on current and past body mass index (BMI) trends. It also tests the impact of obesity interventions on the future disease burden. Setting and participants Secondary data analysis of country-specific epidemiological data using a microsimulation modelling process. Interventions The effect of three hypothetical scenarios on the future burden of disease in 2030 was tested: baseline scenario, BMI trends go unchecked; intervention 1, population BMI decreases by 1%; intervention 2, BMI decreases by 5%. Primary and secondary outcome measures Quantifying the future burden of major NCDs and the impact of interventions on this future disease burden. Results By 2030 in the whole of the European region, the prevalence of diabetes, CHD and stroke and cancers was projected to reach an average of 3990, 4672 and 2046 cases/100 000, respectively. The highest prevalence of diabetes was predicted in Slovakia (10 870), CHD and stroke—in Greece (11 292) and cancers—in Finland (5615 cases/100 000). A 5% fall in population BMI was projected to significantly reduce cumulative incidence of diseases. The largest reduction in diabetes and CHD and stroke was observed in Slovakia (3054 and 3369 cases/100 000, respectively), and in cancers was predicted in Germany (331/100 000). Conclusions Modelling future disease trends is a useful tool for policymakers so that they can allocate resources effectively and implement policies to prevent NCDs. Future research will allow real policy interventions to be tested; however, better surveillance data on NCDs and their risk factors are essential for research and policy. PMID:25063459

Localized time-lapse elastic waveform inversion using wavefield injection and extrapolation: 2-D parametric studies

NASA Astrophysics Data System (ADS)

Yuan, Shihao; Fuji, Nobuaki; Singh, Satish; Borisov, Dmitry

2017-06-01

We present a methodology to invert seismic data for a localized area by combining source-side wavefield injection and receiver-side extrapolation method. Despite the high resolving power of seismic full waveform inversion, the computational cost for practical scale elastic or viscoelastic waveform inversion remains a heavy burden. This can be much more severe for time-lapse surveys, which require real-time seismic imaging on a daily or weekly basis. Besides, changes of the structure during time-lapse surveys are likely to occur in a small area rather than the whole region of seismic experiments, such as oil and gas reservoir or CO2 injection wells. We thus propose an approach that allows to image effectively and quantitatively the localized structure changes far deep from both source and receiver arrays. In our method, we perform both forward and back propagation only inside the target region. First, we look for the equivalent source expression enclosing the region of interest by using the wavefield injection method. Second, we extrapolate wavefield from physical receivers located near the Earth's surface or on the ocean bottom to an array of virtual receivers in the subsurface by using correlation-type representation theorem. In this study, we present various 2-D elastic numerical examples of the proposed method and quantitatively evaluate errors in obtained models, in comparison to those of conventional full-model inversions. The results show that the proposed localized waveform inversion is not only efficient and robust but also accurate even under the existence of errors in both initial models and observed data.

Coping with the New Era: Noise and Light Pollution, Hperactivity and Steroid Hormones. Towards an Evolutionary View of Bipolar Disorders.

PubMed

Carta, M G; Preti, A; Akiskal, H S

2018-01-01

Human population is increasing in immense cities with millions of inhabitants, in which life is expected to run 24 hours a day for seven days a week (24/7). Noise and light pollution are the most reported consequences, with a profound impact on sleep patterns and circadian biorhythms. Disruption of sleep and biorhythms has severe consequences on many metabolic pathways. Suppression of melatonin incretion at night and the subsequent effect on DNA methylation may increase the risk of prostate and breast cancer. A negative impact of light pollution on neurosteroids may also affect mood. People who carry the genetic risk of bipolar disorder may be at greater risk of full-blown bipolar disorder because of the impact of noise and light pollution on sleep patterns and circadian biorhythms. However, living in cities may also offers opportunities and might be selective for people with hyperthymic temperament, who may find themselves advantaged by increased energy prompted by increased stimulation produced by life in big cities. This might result in the spreading of the genetic risk of bipolar disorder in the coming decades. In this perspective the burden of poor quality of life, increased disability adjusted life years and premature mortality due to the increases of mood disorders is the negative side of a phenomenon that in its globality also shows adaptive aspects. The new lifestyle also influences those who adapt and show behaviors, reactions and responses that might resemble the disorder, but are on the adaptive side.

Pre-post changes in psychosocial functioning among relatives of patients with depressive disorders after Brief Multifamily Psychoeducation: A pilot study

PubMed Central

2011-01-01

Background Depressive disorder is often chronic and recurrent, and results in a heavy psychosocial burden on the families of patients with this disorder. This study aims to examine the effectiveness of brief multifamily psychoeducation designed to alleviate their psychosocial burden. Methods Thirty-two relatives of patients with major depressive disorder participated in an open study testing the effectiveness of brief multifamily psychoeducation. The intervention consisted of four sessions over the course of 6 weeks. Outcome measures focused on emotional distress, care burden and Expressed Emotion (EE). Results The emotional distress, care burden and EE of the family all showed statistically significant improvements from baseline to after the family intervention. The proportion of relatives scoring 9 or more on K6, which indicates possible depressive or anxiety disorder, decreased from sixteen relatives (50.0%) at baseline, to only 3 relatives (9.3%) after the intervention. Conclusions This study suggests that brief multifamily psychoeducation is a useful intervention to reduce the psychosocial burden of the relatives of patients with depressive disorder. Further evaluation of family psychoeducation for relatives of patients with depressive disorder is warranted. PMID:21477384

Systems perspective: understanding care giving of the elderly in India.

2009-12-01

In this article I propose a systems model of elder care giver burden among Indian care givers. The systems model specifies the effects of elder characteristics, family structure, and personal characteristics of the care giver on care giver burden. Sampling was conducted using a multistage probability method to generate a sample of 259 care givers. The care giver burden questionnaire was translated from English to Hindi and then back into English and pilot tested before implementation. The care givers were interviewed via face-to-face interviews. Regression analysis was used to estimate the effects of the hypothesized determinants on care giver burden. The r square explained 46% of the variance in care giver burden. The following variables were significant from three dimensions: personal characteristics, elder characteristics, and family level. Personal characteristics of the care giver included whether they adhered to Asian cultural norms, the age of the care giver, and gender. Elder characteristics included behavioral problems of the elder. Family functional variables included number of care giving tasks provided by the care giver, and level of family income. Social work practice issues are discussed in the context of this study.

Coping with information style and family burden: Possible roles of self-stigma and hope among parents of children in a psychiatric inpatient unit.

PubMed

2017-05-01

Parents of children who are hospitalized in inpatient psychiatric units must cope with significant challenges. One of these challenges relates to the way in which they cope with illness-related information. The current study examined the relationship between two such coping styles - monitoring and blunting - and family burden among parents of children in a psychiatric inpatient unit. Moreover, the possible moderating roles played by hope and self-stigma in these associations were also examined. Questionnaires regarding coping with information style, self-stigma, hope and family burden were administered to 70 parents. A main positive effect of hope and a main negative effect of self-stigma were uncovered. An interaction between self-stigma and monitoring was also revealed, suggesting that for parents with high self-stigma, compared to those with low self-stigma, more monitoring was related to more burden. Tailoring family interventions according to coping style and self-stigma is highly recommended as a mean to reduce the family burden of parents whose child is hospitalized in a psychiatric inpatient unit.

Family caregivers of people with dementia

PubMed Central

Brodaty, Henry; Donkin, Marika

2009-01-01

Family caregivers of people with dementia, often called the invisible second patients, are critical to the quality of life of the care recipients. The effects of being a family caregiver, though sometimes positive, are generally negative, with high rates of burden and psychological morbidity as well as social isolation, physical ill-health, and financial hardship. Caregivers vulnerable to adverse effects can be identified, as can factors which ameliorate or exacerbate burden and strain. Psychosocial interventions have been demonstrated to reduce caregiver burden and depression and delay nursing home admission. Comprehensive management of the patient with dementia includes building a partnership between health professionals and family caregivers, referral to Alzheimer's Associations, and psychosocial interventions where indicated.

Predicting caregiver burden in general veterinary clients: Contribution of companion animal clinical signs and problem behaviors.

PubMed

Spitznagel, M B; Jacobson, D M; Cox, M D; Carlson, M D

2018-06-01

Caregiver burden, found in many clients with a chronically or terminally ill companion animal, has been linked to poorer psychosocial function in the client and greater utilization of non-billable veterinary services. To reduce client caregiver burden, its determinants must first be identified. This study examined if companion animal clinical signs and problem behaviors predict veterinary client burden within broader client- and patient-based risk factor models. Data were collected in two phases. Phase 1 included 238 companion animal owners, including those with a sick companion animal (n=119) and matched healthy controls (n=119) recruited online. Phase 2 was comprised of 602 small animal general veterinary hospital clients (n=95 with a sick dog or cat). Participants completed cross-sectional online assessments of caregiver burden, psychosocial resources (social support, active coping, self-mastery), and an item pool of companion animal clinical signs and problem behaviors. Several signs/behaviors correlated with burden, most prominently: weakness, appearing sad/depressed or anxious, appearing to have pain/discomfort, change in personality, frequent urination, and excessive sleeping/lethargy. Within patient-based risk factors, caregiver burden was predicted by frequency of the companion animal's signs/behaviors (P<.01). Within client-based factors, potentially modifiable factors of client reaction to the animal's signs/behaviors (P=.01), and client sense of control (P<.04) predicted burden. Understanding burden may enhance veterinarian-client communication, and is important due to potential downstream effects of client burden, such as higher workload for the veterinarian. Supporting the client's sense of control may help alleviate burden when amelioration of the companion animal's presentation is not feasible. Copyright © 2018 Elsevier Ltd. All rights reserved.

Disease burden attributed to alcohol: How methodological advances in the Global Burden of Disease 2013 study have changed the estimates in Sweden.

2016-08-01

The Global Burden of Disease (GBD) study continuously refines its estimates as new data and methods become available. In the latest iteration of the study, GBD 2013, changes were made related to the disease burden attributed to alcohol. The aim of this study was to briefly present these changes and to compare the disease burden attributed to alcohol in Swedish men and women in 2010 using previous and updated methods. In the GBD study, the contribution of alcohol to the burden of disease is estimated by theoretically assessing how much of the disease burden can be avoided by reducing the consumption of alcohol to zero. The updated methods mainly consider improved measurements of alcohol consumption, including less severe alcohol dependence, assigning the most severe injuries and removing the protective effect of drinking on cardiovascular diseases if combined with binge drinking. The overall disease burden attributed to alcohol in 2010 increased by 14% when using the updated methods. Women accounted for this overall increase, mainly because the updated methods led to an overall higher alcohol consumption in women. By contrast, the overall burden decreased in men, one reason being the lower overall alcohol consumption with the new methods. In men, the inclusion of less severe alcohol dependence resulted in a large decrease in the alcohol attributed disease burden. This was, however, evened out to a great extent by the increase in cardiovascular disease and injuries. CONCLUSIONS WHEN USING THE UPDATED GBD METHODS, THE OVERALL DISEASE BURDEN ATTRIBUTED TO ALCOHOL INCREASED IN WOMEN, BUT NOT IN MEN. © 2016 the Nordic Societies of Public Health.

Climate change influences human health in various ways, and quantitative assessments of the effect of climate change on health at national level are becoming essential for environmental health management. This study quantified the burden of disease attributable to climate change in Korea using disability-adjusted life years (DALY), and projected how this would change over time. Diseases related to climate change in Korea were selected, and meteorological data for each risk factor of climate change were collected. Mortality was calculated, and a database of incidence and prevalence was established. After measuring the burden of each disease, the total burden of disease related to climate change was assessed by multiplying population-attributable fractions. Finally, an estimation model for the burden of disease was built based on Korean climate data. The total burden of disease related to climate change in Korea was 6.85 DALY/1000 population in 2008. Cerebrovascular diseases induced by heat waves accounted for 72.1% of the total burden of disease (hypertensive disease 1.82 DALY/1000 population, ischaemic heart disease 1.56 DALY/1000 population, cerebrovascular disease 1.56 DALY/1000 population). According to the estimation model, the total burden of disease will be 11.48 DALY/1000 population in 2100, which is twice the total burden of disease in 2008. This study quantified the burden of disease caused by climate change in Korea, and provides valuable information for determining the priorities of environmental health policy in East Asian countries with similar climates.

Social modeling has the capacity to shape treatment outcomes, including side effects. This study investigated the influence of social modeling of treatment side effects, gender, and participant empathy, on side effects of a placebo treatment. Ninety-six participants (48 females) completed a study purportedly investigating the influence of modafinil (actually placebo) on alertness and fatigue. The participants were randomly seated with a male or female confederate and saw this confederate report experiencing side effects or no side effects. Participant empathy was assessed at baseline. Changes in modeled and general symptoms, and misattribution of symptoms, were assessed during the session and at 24-hr follow-up. During the experimental session, seeing side effect modeling significantly increased modeled symptoms (p = .023, d = 0.56) but not general or misattributed symptoms. Regardless of modeling condition, female participants seated with a female model reported significantly more general symptoms during the session. However, response to social modeling did not differ significantly by model or participant gender. At follow-up, the effect of social modeling of side effects had generalized to other symptoms, resulting in significantly higher rates of modeled symptoms (p = .023, d = 0.48), general symptoms (p = .013, d = 0.49), and misattributed symptoms (p = .022, d = 0.50). The experience of modeled symptoms in response to social modeling was predicted by participants' levels of baseline empathy. Social modeling of symptoms can increase the side effects following treatment, and this effect appears to generalize to a broader range of symptoms and symptom misattribution over time. Higher baseline empathy seems to increase response to social modeling.

Prediction of adverse drug reactions is an important problem in drug discovery endeavors which can be addressed with data-driven strategies. SIDER is one of the most reliable and frequently used datasets for identification of key features as well as building machine learning models for side effects prediction. The inherently unbalanced nature of this data presents with a difficult multi-label multi-class problem towards prediction of drug side effects. We highlight the intrinsic issue with SIDER data and methodological flaws in relying on performance measures such as AUC while attempting to predict side effects.We argue for the use of metrics that are robust to class imbalance for evaluation of classifiers. Importantly, we present a ‘hierarchical anatomical classification schema’ which aggregates side effects into organs, sub-systems, and systems. With the help of a weighted performance measure, using 5-fold cross-validation we show that this strategy facilitates biologically meaningful side effects prediction at different levels of anatomical hierarchy. By implementing various machine learning classifiers we show that Random Forest model yields best classification accuracy at each level of coarse-graining. The manually curated, hierarchical schema for side effects can also serve as the basis of future studies towards prediction of adverse reactions and identification of key features linked to specific organ systems. Our study provides a strategy for hierarchical classification of side effects rooted in the anatomy and can pave the way for calibrated expert systems for multi-level prediction of side effects.

Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of lenses has been lacking. Among the general lay public, misconceptions on eye-sun protection have been identified. For example, sun protection is mainly ascribed to sunglasses, but less so to clear lenses. Skin malignancies in the periorbital region are frequent, but usual topical skin protection does not include the lids. Recent research utilized exact dosimetry and demonstrated relevant differences in UV burden to the eye and skin at a given ambient irradiation. Chronic UV effects on the cornea and lens are cumulative, so effective UV protection of the eyes is important for all age groups and should be used systematically. Protection of children’s eyes is especially important, because UV transmittance is higher at a very young age, allowing higher levels of UV radiation to reach the crystalline lens and even the retina. Sunglasses as well as clear lenses (plano and prescription) effectively reduce transmittance of UV radiation. However, an important share of the UV burden to the eye is explained by back reflection of radiation from lenses to the eye. UV radiation incident from an angle of 135°–150° behind a lens wearer is reflected from the back side of lenses. The usual antireflective coatings considerably increase reflection of UV radiation. To provide reliable labeling of the protective potential of lenses, an eye-sun protection factor (E-SPF®) has been developed. It integrates UV transmission as well as UV reflectance of lenses. The E-SPF® compares well with established skin-sun protection factors and provides clear messages to eye health care providers and to lay consumers. PMID:24379652

Clostridium difficile infection (CDI) is the most important cause of healthcare-associated infectious diarrhea in industrialized countries. We performed a literature review of the overall economic burden of initial and recurrent CDI as well as of the cost-effectiveness of the various treatment strategies applied in these settings. Even though analysis of health economic data is complicated by the limited comparability of results, our review identified several internationally consistent results. Authors from different countries have shown that recurrent CDI disproportionally contributes to the overall economic burden of CDI and therefore offers considerable saving potential. Subsequent cost-effectiveness analyses almost exclusively identified fidaxomicin as the preferred treatment option for initial CDI and fecal microbiota transplant (FMT) for recurrent CDI. Among the various FMT protocols, optimum results were obtained using early colonoscopy-based FMT. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Caregivers of patients with dementia experience physical and mental deterioration. We have previously reported a correlation between caregiver burden and the Frontal Assessment Battery (FAB) total scores of patients with Alzheimer's disease (AD), especially regarding the dependency factor from the Zarit Burden Interview. The present study aimed to identify an objective biomarker for predicting caregiver burden. The participants were 26 pairs of caregivers and patients with AD and mild-to-moderate dementia. Correlations between regional gray matter volumes in the patients with AD and the FAB total scores were explored by using whole-brain voxel-based morphometric analysis. Path analysis was used to estimate the relationships between regional gray matter volumes, FAB total scores, and caregiver burden based on the Zarit Burden Interview. The voxel-based morphometric revealed a significant positive correlation between the FAB total scores and the volume of the left dorsolateral prefrontal cortex. This positive correlation persisted after controlling for the effect of general cognitive dysfunction, which was assessed by using the Mini-Mental State Examination. Path analysis revealed that decreases in FAB scores, caused by reduced frontal lobe volumes, negatively affected caregiver burden. The present study revealed that frontal lobe function, based on FAB scores, was affected by the volume of the left dorsolateral prefrontal cortex. Decreased scores were associated with greater caregiver burden, especially for the dependency factor. These findings may facilitate the development of an objective biomarker for predicting caregiver burden. Copyright © 2017 John Wiley & Sons, Ltd.

This paper reports on a strategy to improve and renovate assembly lines, including countermeasures to prevent low back pain during the past two decades at Toyota Motor Co. Since 1975, there have been problems with low back pain at Toyota's vehicle assembly lines. To deal with these low back pain problems, it was necessary to determine their causes and to quantitatively evaluate the burden on workers. For this purpose, functional burden indexes were developed, that is, a posture burden point and a weight burden point were determined to assess the load on the low back, and a low extremity point and a squatting posture point were determined to assess the burden on the leg. The functional burden index, however, could be applied only to specific human functions, not to human functions in general. Since there are about 400 kinds of working patterns in vehicle assembly lines, comprehensive burden index was required to estimate overall burden of such work. Thus, we developed Toyota's Verification of Assembly Line (TVAL), an index for assessing the physiological stress of an assembly line work, in which an equivalent bicycle ergometer workload is calculated from electromyograms taken of 20 different muscles under actual working conditions. At present, TVAL is used to measure physiological burden of assembly work in order to give priority to improvements, and to objectively demonstrate the effects of such improvements at Toyota.

The sensitivity of fish to a transmitter depends on factors such as environmental conditions, fish morphology, life stage, rearing history, and tag design. However, synthesizing general trends across studies is difficult because each study focuses on a particular performance measure, species, life stage, and transmitter model. These differences motivated us to develop simple metrics that allow effects of transmitters to be compared among different species, populations, or studies. First, we describe how multiple regression analysis can be used to quantify the effect of tag burden (transmitter mass relative to fish mass) on measures of physiological performance. Next, we illustrate how the slope and intercept parameters can be used to calculate two summary statistics: θ, which estimates the tag burden threshold above which the performance of tagged fish begins to decline relative to untagged fish; and k, which measures the percentage change in performance per percentage point increase in tag burden. When θ = 0, k provides a single measure of the tag's effect that can be compared among species, populations, or studies. We apply this analysis to two different experiments that measure the critical swimming speed (U crit) of tagged juvenile Chinook Salmon Oncorhynchus tshawytscha. In both experiments, U crit declined as tag burden increased, but we found no significant threshold in swimming performance. Estimates of θ ranged from −0.6% to 2.1% among six unique treatment groups, indicating that swimming performance began to decline at a relatively low tag burden. Estimates of k revealed that U crit of tagged fish declined by −2.68% to −4.86% for each 1% increase in tag burden. Both θ and k varied with the tag's antenna configuration, tag implantation method, and posttagging recovery time. Our analytical approach can be used to gain insights across populations to better understand factors affecting the ability of fish to carry a transmitter.
