    Economic theory distinguishes two concepts of utility: decision utility, objectively quantifiable by choices, and experienced utility, referring to the satisfaction by an obtainment. To date, experienced utility is typically measured with subjective ratings. This study intended to quantify experienced utility by global levels of neuronal activity. Neuronal activity was measured by means of electroencephalographic (EEG) responses to gain and omission of graded monetary rewards at the level of the EEG topography in human subjects. A novel analysis approach allowed approximating psychophysiological value functions for the experienced utility of monetary rewards. In addition, we identified the time windows of the event-related potentials (ERP) and the respective intracortical sources, in which variations in neuronal activity were significantly related to the value or valence of outcomes. Results indicate that value functions of experienced utility and regret disproportionally increase with monetary value, and thus contradict the compressing value functions of decision utility. The temporal pattern of outcome evaluation suggests an initial (∼250 ms) coarse evaluation regarding the valence, concurrent with a finer-grained evaluation of the value of gained rewards, whereas the evaluation of the value of omitted rewards emerges later. We hypothesize that this temporal double dissociation is explained by reward prediction errors. Finally, a late, yet unreported, reward-sensitive ERP topography (∼500 ms) was identified. The sources of these topographical covariations are estimated in the ventromedial prefrontal cortex, the medial frontal gyrus, the anterior and posterior cingulate cortex and the hippocampus/amygdala. The results provide important new evidence regarding "how," "when," and "where" the brain evaluates outcomes with different hedonic impact. PMID:21775593

    Complementing the commonly used concepts of evaluative wellbeing and decision utility, emotional wellbeing and experienced utility are important welfare criteria to assess individuals' subjective wellbeing, especially for valuing health and disability. Yet, almost all empirical evidences on the link between disability and experienced wellbeing come from developed countries. This paper studies the relationship between old-age disability and experienced utility in five low- and middle-income countries. Using data on individual time use and activity-specific affective experiences from an abbreviated version of the Day Reconstruction Method, we document a strong negative association between disability and experienced utility. These differences in experienced utility by disability status are exclusively due to worse activity-specific affective experiences among persons with disabilities. By contrast, disability-related differences in time use provide small compensating effects. Interventions or technologies that facilitate daily life hold most promise to improve experienced utility among persons with disabilities in the developing world. PMID:26496227

    This article analyses problem situations in the context of anaesthesia care. It considers what it means for nurse anaesthetists to be in problematic situations in the anaesthesia care of older patients. Benner's interpretive phenomenological approach proved useful for this purpose. Paradigm cases are used to aid the analysis of individual nurses' experiences. Thirty narrated problematic anaesthesia care situations derived from seven interviews were studied. These show that experienced nurse anaesthetists perceive anaesthesia care as problematic and highly demanding when involving older patients. To be in problematic anaesthesia care situations means becoming morally distressed, which arises from the experience or from being prevented from acting according to one's legal and moral duty of care. An important issue that emerged from this study was the need for an ethical forum to discuss and articulate moral issues, so that moral stress of the kind experienced by these nurse anaesthetists can be dealt with and hopefully reduced.

    Objectives: Physicians often deal with emotions arising from both patients and themselves; however, management of intense emotions when they arise in the presence of patients is overlooked in research. The aim of this study is to inspect physicians’ intense emotions in this context, how these emotions are displayed, coping strategies used, adjustment behaviors, and the impact of the emotional reactions on the physician-patient relationship. Methods: A total of 127 physicians completed a self-report survey, built from a literature review. Participants were recruited in 3 different ways: through a snowball sampling procedure, via institutional e-mails, and in person during service meetings. Results: Fifty-two physicians (43.0%) reported experiencing intense emotions frequently. Although most physicians (88.6%) tried to control their reactions, several reported not controlling themselves. Coping strategies to deal with the emotion at the moment included behavioral and cognitive approaches. Only the type of reaction (but not the emotion’s valence, duration, relative control, or coping strategies used) seemed to affect the physician-patient relationship. Choking-up/crying, touching, smiling, and providing support were significantly associated with an immediate positive impact. Withdrawing from the situation, imposing, and defending oneself were associated with a negative impact. Some reactions also had an extended impact into future interactions. Conclusion: Experiencing intense emotions in the presence of patients was frequent among physicians, and the type of reaction affected the clinical relationship. Because many physicians reported experiencing long-lasting emotions, these may have important clinical implications for patients visiting physicians while these emotions last. Further studies are needed to clarify these results. PMID:27479947

    Background Patients undergoing treatment for malignant gliomas (MGs) can encounter medical costs beyond what their insurance covers. The magnitude and type of costs experienced by patients are unknown. The purpose of this study was to have patients or their families report on the medical costs incurred during the patients MG treatment. Methods Patients with MG were eligible if they were within 6 months of diagnosis or tumor recurrence. Patients had to be ≥18 years of age, fluent in English, and not aphasic. Weekly logbooks were issued to patients for recording associated costs for ∼6 months or until tumor progression. “Out-of-pocket” (OOP) costs included medical and nonmedical expenses that were not reimbursed by insurance. Direct medical costs included hospital and physician bills. Direct nonmedical costs included transportation, parking, and other related items. Indirect medical costs included lost wages. Costs were analyzed to provide mean and medians with range of expenses. Results Forty-three patients provided cost data for a median of 12 weeks. There were 25 men and 18 women with a median age of 57 years (range, 24y–73y); 79% were married, and 49% reported annual income >$75 000. Health insurance coverage was preferred provider organizations for 58% of patients, and median deductible was $1 500. Median monthly OOP cost was $1 342 (mean, $2 451; range, $333.41–$17 267.16). The highest OOP median costs were medication copayments ($710; range, $0–13 611.20), transportation ($327; range, $0–$1 927), and hospital bill copayments ($403; range, $0–$4 000). Median lost wages were $7 500, and median lost days of work were 12.8. Conclusions OOP costs for MG patients can be significant and comprise direct and indirect costs across several areas. Informing patients about expected costs could limit additional duress and allow financial support systems to be implemented. PMID:26034619

    Objectives Environmental sound perception serves an important ecological function by providing listeners with information about objects and events in their immediate environment. Environmental sounds such as car horns, baby cries or chirping birds can alert listeners to imminent dangers as well as contribute to one's sense of awareness and well being. Perception of environmental sounds as acoustically and semantically complex stimuli, may also involve some factors common to the processing of speech. However, very limited research has investigated the abilities of cochlear implant (CI) patients to identify common environmental sounds, despite patients' general enthusiasm about them. This project (1) investigated the ability of patients with modern-day CIs to perceive environmental sounds, (2) explored associations among speech, environmental sounds and basic auditory abilities, and (3) examined acoustic factors that might be involved in environmental sound perception. Design Seventeen experienced postlingually-deafened CI patients participated in the study. Environmental sound perception was assessed with a large-item test composed of 40 sound sources, each represented by four different tokens. The relationship between speech and environmental sound perception, and the role of working memory and some basic auditory abilities were examined based on patient performance on a battery of speech tests (HINT, CNC, and individual consonant and vowel tests), tests of basic auditory abilities (audiometric thresholds, gap detection, temporal pattern and temporal order for tones tests) and a backward digit recall test. Results The results indicated substantially reduced ability to identify common environmental sounds in CI patients (45.3%). Except for vowels, all speech test scores significantly correlated with the environmental sound test scores: r = 0.73 for HINT in quiet, r = 0.69 for HINT in noise, r = 0.70 for CNC, r = 0.64 for consonants and r = 0.48 for vowels.

    2016-01-01

    This paper focuses on the mental patients in Arabo-Islamic Middle Ages. Patients suffering from mental illnesses generated a lot of interest for Arabo-Islamic physicians. The first objective of this study is to identify who were the mentally infirm and to compare the Arab physicians' typologies of mental patients to that of their Greek predecessors. The second part of this paper shifts the focus from theoretical descriptions to case histories and biographical sources, in order to understand how the physicians treated their mental patients, and to find out what was the social impact of this medical approach. Finally, because the special provision for the insane is a distinctive feature of the Islamic hospital, the third part of my paper examines whether the main purpose of these hospitals was the patients' confinement or their treatment.

    Background/Aims It is essential that clinicians have an understanding of patients’ perceptions of constipation as well as constipation mis-perception (CM), which can be defined as failure to recognize the six constipation symptoms (infrequency, straining, hard stool, incomplete evacuation, anorectal obstruction or manual maneuver). The aims of our study were to identify the prevalence of CM and its association with demographics and clinical features. Methods This nationwide survey included 625 self-reported constipated subjects (431 females; mean age, 41.2 years) among random participants in the National Health Screening Program. The prevalence of CM for each constipation symptom was estimated, and the participants were classified into nil (0), low (1–2), mid (3–4) and high (5–6) level CM subgroups according to the number of misperceived symptoms. Results The highest rate of CM was observed for manual maneuver (48.3%), followed by anorectal obstruction (38.4%), stool infrequency (34.6%), incomplete evacuation (32.2%), hard stool (27.2%) and straining (25.4%). Among the nil (n = 153), low (n = 242), mid (n = 144) and high level (n = 86) subgroups, there were significant differences in the proportions of males (18.3%, 34.3%, 39.6% and 30.2%; P = 0.001, respectively), never-married status (25.7%, 38.2%, 36.8% and 45.9%; P = 0.030, respectively) and those who did not receive treatment for constipation (41.8%, 47.5%, 58.3% and 66.3%; P < 0.001, respectively). There was a significant linear trend of increasing degree of CM with decreasing symptoms experienced (P < 0.001). Conclusions CM is significantly associated with gender, marital status, treatment utilization and the range of constipation symptoms experienced. PMID:24935009

    Background Fractures in older patients are common, morbid, and associated with increased risk of subsequent fractures. Inpatient and outpatient management and treatment of fractures can be costly. With more emphasis placed on quality care for Medicare beneficiaries, we studied if patients were receiving proper screening for osteoporosis and treatment after diagnosis of fracture. This study aims to determine if adequate screening and treatment for osteoporosis occurs in the postfracture period. Methods A retrospective analysis of Medicare beneficiaries aged 67 years or older was gathered from a single institution in both inpatient and outpatient visits. Based on International Classification of Diseases ninth revision codes, primary diagnosis of fractures of neck and trunk, upper limb, and lower limb were obtained in addition to current procedural terminology codes for fracture procedures. We studied patients who had been screened for osteoporosis with a bone mineral study or received osteoporosis treatment after their fracture. Results Medicare beneficiaries totaling 1,375 patients were determined to have an inclusion fracture between June 1, 2013 and November 30, 2014. At the time of our analysis on December 1, 2014, 1,219 patients were living and included in the analysis. Of these patients, 256 (21.0%) either received osteoporosis testing with bone mineral density or received treatment for osteoporosis. On sex breakdown, 208/820 (25.4%) females received proper evaluation or treatment of osteoporosis in comparison to 48/399 (12.0%) males. This is in comparison to the Centers for Medicare and Medicaid Services’ national average of 19.1% for osteoporosis management in females. Conclusion A minority of studied patients received evaluation or treatment for osteoporosis after their fracture. Postfracture investigation and treatment for osteoporosis in Medicare beneficiaries is inadequate. If improved, Medicare costs could be reduced by prevention of future fractures

    During the last 20 years, numerous studies have highlighted the need to consider Quality of Life (QoL) issues in the treatment of brain cancer. However, gaps in scientific knowledge are still present as we have poor data surrounding the whole experience in patients and regarding their needs. The present study was aimed at evaluating QoL in brain cancer patients and correlated aspects. In particular, we aimed to assess QoL, mood state, and emotional issues in order to describe the patients’ experience to find out the critical aspects involved. Methods We obtained data from 85 patients during chemotherapy treatment at the National Neurological Institute ‘C. Besta’ of Milan, Italy. We used standardised questionnaires to assess different aspects of patients’ QoL. In particular, the functional assessment of cancer therapy-brain (FACT-Br) and the Hamilton scale were used. We also performed a semi-structured ad hoc interview in order to collect ­narrative data about patients’ experience. Results Our data depict a difficult adjustment process to the illness, even though positive elements emerged. Indeed, patients reported a satisfying self-perceived QoL, although specific concerns are still present. Further, even if many patients report depressive symptoms, only a minority have a severe condition. Conclusion Brain cancer may heavily affect patients’ QoL and well being. However, some element of the context may improve the ­adjustment to the disease. In particular, we found that most patients found psychosocial resources to cope with cancer and that spiritual well being also seems to play a key role. These issues deserve further studies in order to obtain significant clinical recommendations. PMID:26635895

    The purpose of this study was to assess the physiological strain experienced by North American electrical utility workers during the performance of their normal work duties in heat stressed conditions. Three common job categories were monitored as they are normally performed in 32 electrical utility workers: (i) Ground Work (n = 11); (ii) Bucket Work (n = 9); and (iii) Manual Pole Work (n = 12). Worker hydration status (urine specific gravity (USG)) was measured prior to and following the work monitoring period (duration: 187 ± 104 min). Core and skin temperatures as well as heart rate were measured continuously. Physiological Strain Index (PSI) was calculated from the measurements of core temperature and heart rate. Prior to the start of the work shift, 38% of workers were euhydrated (USG < 1.020; n = 12) whereas the majority of workers were dehydrated (USG > 1.020; prevalence: 75%; p < 0.01) following work. The overall mean and peak core temperatures for all monitored workers were 37.9 ± 0.3 °C and 38.3 ± 0.5 °C, respectively. When responses were compared between job categories, greater mean and peak increases in core temperature were observed in Manual Pole Work relative to the other job categories (both p < 0.04). In fact, six workers performing Manual Pole Work achieved core temperatures in excess of 38.5 °C, while only one other worker surpassed this threshold in Bucket Work. The high levels of thermal strain were paralleled by elevated mean and peak heart rate and PSI responses, which were greater in Manual Pole Work in comparison to the other job categories (all p ≤ 0.05). Furthermore, two workers performing Manual Pole Work achieved severely elevated core temperatures reaching or exceeding 39.5 °C along with prolonged periods of near maximal heart rate responses (i.e., >90% of heart rate reserve). We report elevated levels of thermal and cardiovascular strain in electrical utility workers during work in the heat and potentially dangerous levels of

    Darunavir is currently the most recently approved HIV-1 protease inhibitor. It is approved for twice-daily dosing with ritonavir in treatment-experienced patients as young as 6 years of age and is available in numerous pill strengths. Emergence of darunavir-specific mutations is generally slow; therefore it can retain activity against viral strains that are resistant to other protease inhibitors, including tipranavir. Darunavir pharmacokinetics, clinical efficacy, resistance mutations and pharmacodynamics, and adverse effects are reviewed here. Substantial data support its use as a potent, well-tolerated option for salvage therapy in highly treatment-experienced children and adolescents. PMID:19707276

    The relationship between medical and psychiatric utilization of services was examined in a two-year study of two groups of psychiatric patients: high users of psychiatric services (more than ten visits in one year) and low users of psychiatric services (ten or fewer visits in one year). The high-utilization group made more than 60 per cent of the total psychiatric visits in the two-year period, but only 21 per cent of the total medical visits. However, patients in this group increased their utilization of medical services when psychiatric utilization was reduced, raising the question of whether high-utilization patients tend to substitute medical visits for psychiatric visits. In contrast, patients in the low-utilization group were able to hold their medical utilization constant when they reduced psychiatric utilization. Analysis of factors influencing utilization patterns might allow illness behavior in patients to be predetermined and lead to better and more cost-effective health care. PMID:7203418

    Background and Aim. This is an open label prospective cohort study conducted at a tertiary care hospital. The primary endpoint is SVR12 in patients treated with sofosbuvir-based therapy in post-liver transplant patients with genotype 4 HCV recurrence. Methodology. Thirty-six treatment-experienced liver transplant patients with HCV recurrence received sofosbuvir and ribavirin ± peginterferon. Results. We report here safety and efficacy data on 36 patients who completed the follow-up period. Mean age was 56 years, and the cohort included 24 males and one patient had cirrhosis. Mean baseline HCV RNA was 6.2 log10 IU/mL. The majority of patients had ≥ stage 2 fibrosis. Twenty-eight patients were treated with pegylated interferon plus ribavirin in addition to sofosbuvir for 12 weeks and the remaining were treated with sofosbuvir plus ribavirin only for 24 weeks. By week 4, only four (11.1%) patients had detectable HCV RNA. Of the 36 patients, 2 (5.5%) relapsed and one died (2.75%). Conclusion. Our results suggest that sofosbuvir + ribavirin ± pegylated interferon can be utilized successfully to treat liver transplant patients with HCV recurrence. PMID:27446833

    Objectives To evaluate the cost-effectiveness of a new generation integrase inhibitor (INI), dolutegravir (DTG), in France, in treatment-experienced (TE) and INI-naïve HIV-infected adults with at least two classes resistance compared to raltegravir (RAL), by adapting previously published Anti-Retroviral Analysis by Monte Carlo Individual Simulation (ARAMIS) model. Methods ARAMIS is a microsimulation Markov model with a lifetime time horizon and a monthly cycle length. Health states are defined as with or without opportunistic infection and death. In the initial cohort, efficacy and safety data were derived from a phase III study comparing DTG to RAL. Antiretroviral treatment algorithms, accounting for patient history, were based on French guidelines and experts opinion. Costs are mainly including treatment costs, routine HIV and opportunistic infection care, and death. Utilities depend on CD4+ cell count and the occurrence of opportunistic infections. Results The ARAMIS model indicates in the TE population that DTG compared to RAL over a life time is associated with 0.35 additional quality-adjusted life years (QALY; 10.75 versus 10.41) and additional costs of €7,266 (€390,001 versus €382,735). DTG increased costs are mainly related to a 9.1-month increase in life expectancy for DTG compared with RAL, and consequently a longer time spent on ART. The incremental cost-effectiveness ratio (ICER) for DTG compared with RAL is €21,048 per QALY gained. About 83% and 14% of total lifetime costs are associated with antiretroviral therapy and routine HIV care respectively. Univariate deterministic sensitivity analyses demonstrate the robustness of the model. Conclusion DTG is cost-effective in the management of TE INI naive patients in France, from a collective perspective. These results could be explained by the superior efficacy of DTG in this population and its higher genetic barrier to resistance compared to RAL. These data need to be confirmed with longer

    Background Fatigue, a common symptom reported by patients receiving dialysis, is a multidimensional and subjective experience which is readily understood by individuals but difficult to measure. Objectives This study was performed to identify the prevalence of differential aspects of fatigue among patients receiving maintenance dialysis. Patients and Methods The cross-sectional study was conducted in two hemodialysis wards in Tehran with a sample of 163 participants. In this study, the multidimensional fatigue inventory was used to determine the level of fatigue. Demographic data were also collected with self-report survey. To analyze data with SPSS statistical software, test Chi square, T-test, and ANOVA were used. P- Value less than 0.05 was considered significant. Results All the patients experienced degrees of fatigue and 50 (30.7%) of the participants experienced a high level of fatigue. Fatigue scores arrangement was founded for physical fatigue followed by reduced activity and general fatigue. Lower levels of fatigue were reported for mental fatigue and reduced motivation. There was no diversity in this study in the levels of fatigue in respects of gender and marital status and employment status. Participants with diabetic nephropathy were the most fatigued. Conclusions People with chronic kidney disease regardless of their age, gender, state of health, and duration of hemodialysis experience high levels of fatigue; it is particularly important for health providers to understand this level of fatigue which affects the daily life of patients.

    This paper reports on a qualitative study to identify Italian nurses' feelings and emotions towards the management of distressed and disturbed psychiatric patients in acute inpatient settings. Four focus groups were carried out involving 33 nurses from seven acute psychiatric services in a region of Italy. Data were analysed using content analysis. Findings highlight that fear is the prevailing feeling experienced by nurses in the management of distressed patients. This includes both fear of being physically harmed and concerns about doing harm or damage to patients. The unpredictability of aggressive behaviour from unknown patients was described as especially frightening. Known patients, namely those previously admitted to the unit, induced less fear, as their behaviour was considered more predictable. Patients with dual diagnosis were also a worry for many nurses, who considered themselves lacking in the personal relational skills needed to manage an individual in crisis. Nurses reported that they try to understand the reasons for a patient's aggressive behaviour and are empathetic to his or her suffering. When such empathy is lacking, nurses experience conflicting feelings of counter-aggressiveness. The paper concludes by emphasizing the need to increase availability of education related to patient management, in particular team working and its internal relationships. PMID:22296342

    Background After treatment cessation, a high prevalence of relapse was reported in chronic hepatitis B (CHB) patients in China, especially in nucleot(s)ide analogues (NUCs)-experienced patients. Re-treatment for these patients remains unsolved. Objectives This study aims to evaluate the efficacy of PEGylated interferon in HBeAg positive patients with exposure to antiviral therapy. Patients and Methods A total of 55 treatment-experienced, HBeAg positive Chinese patients were enrolled in this study. Of these patients, 33 were NUCs-experienced and 22 were interferon-experienced. PEGylated interferon was administered to 34 patients; and 21 patients were retreated with conventional interferon. Results Of the 34 treatment-experienced patients who received PEGylated interferon, 52.9% achieved virologic response, and 41.2% achieved HBeAg loss and seroconversion. Patients who were treated with PEGylated interferon for 48 weeks achieved higher virologic response (80%); HBeAg loss (60%); HBeAg seroconversion (60%); and HBsAg loss (5%) than patients treated for 24 weeks with PEGylated interferon. Their responses were also higher than those who were treated with conventional interferon. HBeAg seroconversion in treatment-experienced patients was independently associated with 48-week PEGylated interferon therapy duration. Conclusions PEGylated interferon was effective in treatment-experienced patients with HBeAg positive CHB, and showed higher rates of virological response, HBeAg loss, and seroconversion. The results provide important information regarding the role of re-treatment with PEGylated interferon in treatment-experienced HBeAg positive patients. PMID:27257427

    Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could help better understand the pathophysiologic mechanisms involved in exacerbations, establish different strategies of treatment, and improve the process of care and patient prognosis. The objective of this study was to identify subtypes of ECOPD patients attending emergency departments using clinical variables and to validate the results using several outcomes. We evaluated data collected as part of the IRYSS-COPD prospective cohort study conducted in 16 hospitals in Spain. Variables collected from ECOPD patients attending one of the emergency departments included arterial blood gases, presence of comorbidities, previous COPD treatment, baseline severity of COPD, and previous hospitalizations for ECOPD. Patient subtypes were identified by combining results from multiple correspondence analysis and cluster analysis. Results were validated using key outcomes of ECOPD evolution. Four ECOPD subtypes were identified based on the severity of the current exacerbation and general health status (largely a function of comorbidities): subtype A (n = 934), neither high comorbidity nor severe exacerbation; subtype B (n = 682), moderate comorbidities; subtype C (n = 562), severe comorbidities related to mortality; and subtype D (n = 309), very severe process of exacerbation, significantly related to mortality and admission to an intensive care unit. Subtype D experienced the highest rate of mortality, admission to an intensive care unit and need for noninvasive mechanical ventilation, followed by subtype C. Subtypes A and B were primarily related to other serious complications. Hospitalization rate was more than 50% for all the subtypes, although significantly higher for subtypes C and D than for subtypes A and B. These results could help identify characteristics

    Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could help better understand the pathophysiologic mechanisms involved in exacerbations, establish different strategies of treatment, and improve the process of care and patient prognosis. The objective of this study was to identify subtypes of ECOPD patients attending emergency departments using clinical variables and to validate the results using several outcomes. We evaluated data collected as part of the IRYSS-COPD prospective cohort study conducted in 16 hospitals in Spain. Variables collected from ECOPD patients attending one of the emergency departments included arterial blood gases, presence of comorbidities, previous COPD treatment, baseline severity of COPD, and previous hospitalizations for ECOPD. Patient subtypes were identified by combining results from multiple correspondence analysis and cluster analysis. Results were validated using key outcomes of ECOPD evolution. Four ECOPD subtypes were identified based on the severity of the current exacerbation and general health status (largely a function of comorbidities): subtype A (n = 934), neither high comorbidity nor severe exacerbation; subtype B (n = 682), moderate comorbidities; subtype C (n = 562), severe comorbidities related to mortality; and subtype D (n = 309), very severe process of exacerbation, significantly related to mortality and admission to an intensive care unit.

    Resistance to antiretroviral agents is a significant concern in the clinical management of HIV-infected individuals, particularly in areas of the world where treatment options are limited. In this study, we aimed to identify HIV drug-resistance-associated mutations in 40 drug-naïve patients and 62 patients under antiretroviral therapy (ART) referred to the Shiraz HIV/AIDS Research Center - the first such data available for the south of Iran. HIV reverse transcriptase and protease genes were amplified and sequenced to determine subtypes and antiretroviral- resistance-associated mutations (RAMs). Subtype CRF35-AD recombinant was the most prevalent in all patients (98 of 102, 96 %), followed by subtype A1, and subtype B (one each, 2 %). Among the 40 ART-naïve patients, two mutations associated with nucleoside reverse transcriptase inhibitor (NRTI) resistance (two with Y115F and T215I) and three associated with non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance (two with G190S and Y181C, four with V179T) were found. Among ART-experienced patients, four mutations associated with resistance to NRTI, four with NNRTI, and five with protease inhibitors (PI) were found. Twenty patients with high levels of resistance were already on second-line therapy. We document for the first time in this region of Iran high levels of ART resistance to multiple drugs. Our findings call for more vigilant systematic ART resistance surveillance, increased resistance testing, careful management of patients with existing regimens, and strong advocacy for expansion of available drugs in Iran.

    Crohn disease and ulcerative colitis, collectively known as inflammatory bowel disease (IBD), are chronic and have a fluctuating clinical course that impacts daily life. Daily life with a chronic disease involves thinking and worrying about the limitations that chronic disease causes. Knowledge about how patients who suffer from IBD manage critical incidents in daily life is lacking. The aim of the study was to describe how patients living with IBD experience critical incidents in daily life in relation to their disease and symptoms. Thirty adult patients were interviewed focusing on critical incidents in daily life. Data were analyzed using the critical incident technique. The study comprised 224 critical incidents and was grouped into 21 subcategories and 5 categories: losing bowel control, having a body that smells, being unable to meet own and others' expectations, not being believed or seen, and experiencing frustration due to side effects and ineffective treatment. These categories formed one main area describing the overall result "The bowels rule life." The uncertain nature of IBD created critical incidents in which the bowel ruled life, causing patients to avoid social interaction. It also placed considerable demands on the family and sometimes had a negative effect on the afflicted person's career. PMID:26870902

    Objective: This study aims to examine Gender Difference in the level of Discrimination and Stigma experienced by people diagnosed with Major Depressive Disorder in Pakistan. It was hypothesized that Women diagnosed with Depression are likely to be experiencing more Discrimination and Internalized Stigma in comparison to Men. Methods: This is a Cross Sectional Study. Thirty eight patients diagnosed with Major Depressive Disorder recruited from different Government Sector Hospitals of Lahore; were approached after obtaining informed consent. Discrimination and Stigma were measured through Discrimination and Stigma Scale and Internalized Stigma of Mental Illness Inventory respectively. Results: Both Men and Women experience considerably high level of associated Stigma and Discrimination due to their Mental Illness. However, Women in comparison to Men experience significantly greater level of Internalized Stigma especially in domains of Discrimination Experience and Social Withdrawal. Conclusion: The findings of this study highlight the fact that people with Depression can be more benefited with psychological treatment if dealing with Stigma and Discrimination is also addressed in Intervention Plans.

    Cancer patients undergoing chemotherapy experience a range of treatment-related problems, and variations in prevalence exist between treatment centres. A scoping review was undertaken to map reported rates of problem prevalence in the literature. This will inform development of a patient-reported outcome measure (PROM) to monitor prevalence and severity of problems over time and assist service providers optimise supportive care provision. Two databases (Embase and Medline) were searched from 2002 to 2013. Fifty one published papers and conference abstracts reporting problem prevalence rates were identified. The papers reported 98 different problems, from which a typology of 27 problem domains was developed, including both physical symptoms and psychosocial issues. The problem domains most often studied were nausea, vomiting and fatigue. This review reflects the chemotherapy-associated problems to which researchers attach the most importance. The range in reported prevalence across studies was very broad (e.g. nausea: 9-74%), with even less frequently studied problems showing high prevalence in some studies (e.g. gynaecological problems: up to 94%). The wide variation in prevalence and range of problems experienced raises challenges for PROM development. Patients should therefore be involved in consensus exercises to assist selection of items to ensure any instrument is complete and robust. PMID:25296389

    Dolutegravir is an HIV integrase inhibitor with a high genetic barrier to resistance and is active against raltegravir- and/or elvitegravir-resistant strains. The clinical development of dolutegravir for HIV infection rescue therapy is based on 3 clinical trials. In the SAILING trial, dolutegravir (5 mg once daily) in combination with 2 other antiretroviral agents was well tolerated and showed greater virological effect than raltegravir (400 mg twice daily) in the treatment of integrase inhibitor-naïve adults with virological failure infected with HIV strains with at least two-class drug resistance. The VIKING studies were designed to evaluate the efficacy of dolutegravir as rescue therapy in treatment-experienced patients infected with HIV strains with resistance mutations to raltegravir and/or elvitegravir. VIKING-1-2 was a dose-ranging phase IIb trial. VIKING-3 was a phase III trial in which dolutegravir (50 mg twice daily) formed part of an optimized regimen and proved safe and effective in this difficult-to-treat group of patients. Dolutegravir is the integrase inhibitor of choice for rescue therapy in multiresistant HIV infection, both in integrase inhibitor-naïve patients and in those previously treated with raltegravir or elvitegravir.

    High experienced continuity of care in patients with cancer is associated with lower needs for care, better quality of life and better psychological outcomes. We developed and evaluated an intervention to improve experienced continuity. The intervention, consisted of (1) a 17-item patient-completed continuity assessment; (2) feedback to clinical nurse specialists and action to address the needs identified. Multidisciplinary team meetings and oncology outpatient clinics were observed, and patients and staff were interviewed. After qualitative work and reliability testing, the intervention was evaluated in a feasibility trial. Sixty-one patients provided data for analysis. No statistically significant differences were found in patients' experienced continuity between the trial arms, but important trends were seen in measures of needs for care in favour of those receiving the intervention. Feeding back findings from the continuity assessment to clinicians reduced patients' needs for care. Our results indicate that an intervention to target patients' experiences of continuity can reduce their subsequent needs for care. However, overcoming barriers to organisational change and addressing some patients' hesitation to report their continuity difficulties must be considered when implementing such an intervention. A phase III trial targeting patients with inadequate experienced continuity of care is recommended. PMID:19107130

    Different sort of people are interested in personal identity. Philosophers frequently ask what it takes to remain oneself. Caregivers imagine their patients' experience. But both philosophers and caregivers think from the armchair: they can only make assumptions about what it would be like to wake up with massive bodily changes. Patients with a locked-in syndrome (LIS) suffer a full body paralysis without cognitive impairment. They can tell us what it is like. Forty-four chronic LIS patients and 20 age-matched healthy medical professionals answered a 15-items questionnaire targeting: (A) global evaluation of identity, (B) body representation and (C) experienced meaning in life. In patients, self-reported identity was correlated with B and C. Patients differed with controls in C. These results suggest that the paralyzed body remains a strong component of patients' experienced identity, that patients can adjust to objectives changes perceived as meaningful and that caregivers fail in predicting patients' experience.

    Research consistently demonstrates that intensive care unit (ICU) patients experience pain, discomfort and anxiety despite analgesic and sedative use. The most painful procedure reported by critically ill patients is being turned. Music diminishes anxiety and discomfort in some populations; however, its effect on critically ill patients remains unknown. This research aimed to identify the effect of music on discomfort experienced by ICU patients during turning using a single blind randomized cross-over design. Seventeen post-operative ICU patients were recruited and treatment order randomized. Discomfort and anxiety were measured 15 min before and immediately after two turning procedures. Findings indicated that listening to music 15 min before and during turning did not significantly reduce discomfort or anxiety. Pain management might effectively be addressing discomfort and anxiety experienced during turning. Given previous studies have identified turning as painful, current results are promising and it might be useful to determine if this is widespread. PMID:20487057

    Although fatigue is a common symptom in neuromuscular disorders, little is known about different types of fatigue. Sixty-five FSHD, 79 adult-onset MD and 73 HMSN type I patients were studied. Experienced fatigue was assessed with the CIS-fatigue subscale. Physiological fatigue was measured during a 2-min sustained maximal voluntary contraction of the biceps brachii muscle using the twitch interpolation technique to assess central activation failure (CAF) and peripheral fatigue. Experienced fatigue, CAF and peripheral fatigue appeared to be predominantly separate types of fatigue. PMID:18690504

    Study Objectives This study assesses VA mental health providers’ understanding of intimate partner violence (IPV) and the perception of patient benefit of routine inquiry and service referral. The impact of an instructional curriculum was also examined following an interactive training. Methods An evidence-based curriculum was offered to VA mental health providers. The curriculum utilized didactic methods, case scenarios, and resources regarding referrals and statutes regarding crimes related to violence and abuse. The participants completed pre- and post-training surveys to assess their perceptions about IPV and to evaluate the training. Results Seventy-three individuals completed the training. Fifty-four of the participants were female, and thirty-three were over the age of 45. Fifty-one individuals completed both surveys. There were no differences between participants’ views of the seriousness of IPV in the community or their practices before or after the training. However, participants scored significantly higher on the knowledge and efficacy measures after the training (p<.001). Conclusion Following an educational intervention, providers demonstrate more knowledge and efficacy regarding routine inquiry and referral for IPV. Barriers to universal implementation still warrant attention. PMID:22165653

    Disclosure is a prerequisite to receive disease-specific social support. However, in the case of a stigmatised disease, it can also lead to discrimination. We aimed to assess disclosure rates of HIV patients and the reactions they encountered in comparison to patients with chronic viral hepatitis or diabetes mellitus and patients' general perception of disease-specific discrimination. We constructed a self-report questionnaire, anonymously assessing the size of the social environment, the persons who had been informed, and the experienced reactions as perceived by the disclosing patients, to be rated on 1-4 point Likert scales. In addition, patients were asked whether they perceive general discrimination in Germany. One hundred and seventy-one patients were asked to participate. Five rejected, thus questionnaires from 83 patients with HIV, 42 patients with chronic viral hepatitis B (n = 9) or C (n = 33), and 41 patients with insulin-dependent diabetes mellitus (type I n = 14, type II n = 27) were analysed. Whereas the size of the social environment did not differ, HIV-infected patients were least likely to disclose their disease (60.7%, SD ± 31.9) to their social environment as compared to patients with chronic viral hepatitis (84.2 ± 23.3%, p<0.0001), or diabetes mellitus (94.4 ± 10.3%, p<0.0001), respectively. Within the HIV patient group, the mean disclosure rate was highest to partners (90.9%), followed by the public environment (65.2%), friends (59.4%) and family members (43.8%). HIV patients experienced supportive reactions after 79.3 ± 26.4% of disclosures, which was the case in 91.4 ± 19.6% and 75.7 ± 36.1% of patients with hepatitis or diabetes mellitus, respectively. 69.5% of HIV patients stated to perceive general discrimination in Germany. We conclude that HIV patients had experienced supportive reactions after the majority of disclosures, but the low rate points out that their information strategy had been very selective.

    Abstract Background: Alcohol withdrawal symptoms can be difficult to manage and may lead to an intensive care unit (ICU) admission. Patients experiencing severe alcohol withdrawal often require high doses of sedatives, which can lead to respiratory depression and the need for endotracheal intubation. Dexmedetomidine, an alpha-2 adrenoreceptor agonist, provides adequate sedation with little effect on respiratory function when compared to other sedatives. Objective: To evaluate sedation with a continuous infusion of dexmedetomidine versus propofol and/or lorazepam in critically ill patients experiencing alcohol withdrawal. Methods: A retrospective chart review was conducted on ICU admissions between March 2002 and April 2009 for alcohol withdrawal patients who necessitated treatment with a continuous infusion of dexmedetomidine, propofol, and/or lorazepam. Primary outcomes included the incidence of mechanical ventilation, length of mechanical ventilation (if applicable), and ICU and hospital length of stay. Results: Fifteen patients were treated with a continuous infusion of dexmedetomidine, and 17 were treated with an infusion of propofol and/or lorazepam. Two patients (13.3%) required intubation and mechanical ventilation in the dexmedetomidine group versus 10 (58.8%) in the propofol and/or lorazepam group (P = .006). Length of stay in the ICU was 53 hours for patients treated with dexmedetomidine versus 114.9 hours in the propofol and/or lorazepam group (P = .016). Hospital length of stay was less for the dexmedetomidine group, 135.8 hours versus 241.1 hours in the propofol and/or lorazepam group (P = .008). Conclusions: Dexmedetomidine use was associated with a decrease in the incidence of endotracheal intubation when used to sedate patients experiencing alcohol withdrawal. Patients transferred to a lower level of care faster and were discharged from the hospital sooner when treated with dexmedetomidine. PMID:26405310

    Purpose. Whistleblowing is the reporting of illegal, immoral, or illegitimate practices to persons or organizations that may affect the action. The current study compares experienced nurses to nursing students regarding their willingness to blow the whistle to protect a patient's interests. Methods. 165 participants were divided into two groups: 82 undergraduate nursing students and 83 experienced nurses. Participants responded to two vignettes that described a colleague's and a manager's misconduct at work. Results. The nursing students perceived the severity of the misconduct significantly lower compared to the experienced nurses. The nursing students also ranked the internal and external whistleblowing indices higher than the nurses, but the differences did not reach statistical significance. For each of the examined internal and external indices, professional experience was found to be significant in multivariate regression analyses. Conclusions. Even though nursing students perceived the severity of the misconduct significantly lower than the experienced nurses, the students demonstrated a greater readiness to blow the whistle, both internally and externally. Recommendations for handling comparable situations are offered. PMID:25379527

    Amprenavir (APV) is an HIV protease inhibitor (PI) used for the treatment of either naive or PI-experienced HIV-infected patients. Several genotypic resistance pathways in protease gene have been described to be associated to unboosted APV failure (I50V, V32I + I47V, I54L/M, or less commonly I84V, which may be accompanied by one ore more accessory mutations such as L10F, L33F, M46I/L). The aims of this study were to investigate the efficacy up to week 24 of an APV plus ritonavir containing regimen in PI experienced patients and to determine the genotypic resistance profiles emerging in patients failing to this therapy. Forty-nine, PI experienced but APV naïve patients were treated with APV (600 mg bid) plus ritonavir (100 mg bid). By intent-to-treat analysis, the median decrease in viral load (VL) was -1.32 log10 (min +0.6; max -2.8) and -1.46 log10 (min +0.5; max -2.8) 12 and 24 weeks after initiating APV plus ritonavir regimen, respectively. Twelve patients harboured a VL >200 copies/ml at week 24. Among these patients, the selection of mutations previously described with the use of APV as first PI (V32I, L33F, M46I/L, I50V, 54M/L, and I84V) was observed. However, in some cases, mutations classically described after the use of other PIs (V82F and L90M) were selected but always with APV-specific mutations. There was no relation between the resistance pathways selected with either APV or ritonavir plasma minimal concentration, but higher APV plasma minimal concentration were associated with a lower rate of resistance mutations selection.

    Background Understanding the emergence and spread of multidrug-resistant tuberculosis (MDR-TB) is crucial for its control. MDR-TB in previously treated patients is generally attributed to the selection of drug resistant mutants during inadequate therapy rather than transmission of a resistant strain. Traditional genotyping methods are not sufficient to distinguish strains in populations with a high burden of tuberculosis and it has previously been difficult to assess the degree of transmission in these settings. We have used whole genome analysis to investigate M. tuberculosis strains isolated from treatment experienced patients with MDR-TB in Uganda over a period of four years. Methods and Findings We used high throughput genome sequencing technology to investigate small polymorphisms and large deletions in 51 Mycobacterium tuberculosis samples from 41 treatment-experienced TB patients attending a TB referral and treatment clinic in Kampala. This was a convenience sample representing 69% of MDR-TB cases identified over the four year period. Low polymorphism was observed in longitudinal samples from individual patients (2-15 SNPs). Clusters of samples with less than 50 SNPs variation were examined. Three clusters comprising a total of 8 patients were found with almost identical genetic profiles, including mutations predictive for resistance to rifampicin and isoniazid, suggesting transmission of MDR-TB. Two patients with previous drug susceptible disease were found to have acquired MDR strains, one of which shared its genotype with an isolate from another patient in the cohort. Conclusions Whole genome sequence analysis identified MDR-TB strains that were shared by more than one patient. The transmission of multidrug-resistant disease in this cohort of retreatment patients emphasises the importance of early detection and need for infection control. Consideration should be given to rapid testing for drug resistance in patients undergoing treatment to monitor the

    [Purpose] The aim of this study was to assess the medical complications in first-time ischemic stroke patients, to identify the factors related to occurrence of complications. [Subjects and Methods] First-time ischemic stroke patients (n=81) admitted to a tertiary level inpatient rehabilitation center during a 5 year period were included in the study. The attending physiatrist noted the presence of specific medical complications and complications that required transfer to the acute care facility from patient records. The Oxfordshire Community Stroke Project classification was used to define the clinical subtypes of the ischemic stroke patients. The Charlson comorbidity index was used to evaluate co-morbid conditions. Functional disability was assessed using the Functional Independence Measure at admission and discharge. [Results] We found that 88.9% of the patients had at least one complication. The five most common complications were urinary tract infection (48.1%), shoulder pain (37.0%), insomnia (37.0%), depression (32.1%), and musculoskeletal pain other than shoulder pain (32.1%) and 11.1% of patients were transferred to acute care facility during rehabilitation period. Functional Independence Measure scores both at admission and discharge were significantly lower in patients with at least one complication than in patients with no complications. [Conclusion] Medical complications are common among patients undergoing stroke rehabilitation. Close interdisciplinary collaboration between physiatrists and other medical specialities is necessary for optimal management. PMID:27065523

    Multiple sclerosis (MS) can result in significant changes in psychological functioning. Depression and cognitive deficits are commonly present. In addition personality changes have been described. A growing body of research is showing negative impact of psychological stress on disease course. Our study focused on the profile of depression, capacity for coping with stress and experienced distress in patients with MS measured by a performance based method for personality assessment-the Rorschach Inkblot Method (RIM). We included 95 patients with MS and 44 healthy controls. RIM was used with all participants and was scored by the Exner Comprehensive system. Compared to healthy controls MS patients had statistically significantly lower capacity for coping with stress, complexity of information processing, body image, willingness to process emotional stimulation and interpersonal interest. Surprisingly patients had lower experienced distress than controls. We propose that the profile of depression in advanced MS disease might be better described in terms of negative symptoms such as emotional withdrawal and apathy and less with the profile of positive symptoms such as rumination and worry. RIM variables were not significantly associated with the EDSS. Interventions from which patients could benefit are discussed. PMID:24321148

    Integrative Therapies (IT), otherwise known as Complementary and Alternative Medicine, are widely used among pediatric oncology patients, despite a paucity of available evidence. This review summarizes surveys that describe the prevalence of IT use by pediatric oncology patients, both during therapy and in survivorship, as well as the modalities being used. Additionally, the evidence that exists for specific treatments that appear to be efficacious in controlling specific symptoms is described. Finally, there are recommendations for practitioners on how to best counsel patients about IT use. PMID:27417488

    Background. Little is known about temporal trends in frequencies of clinically relevant ARV resistance mutations in HIV strains from U.S. patients undergoing genotypic testing (GT) in routine HIV care. Methods. We analyzed cumulative frequency of HIV resistance among patients in the HIV Outpatient Study (HOPS) who, during 1999–2008 and while prescribed antiretrovirals, underwent GT with plasma HIV RNA >1,000 copies/mL. Exposure ≥4 months to each of three major antiretroviral classes (NRTI, NNRTI and PI) was defined as triple-class exposure (TCE). Results. 906 patients contributed 1,570 GT results. The annual frequency of any major resistance mutations decreased during 1999–2008 (88% to 79%, P = 0.05). Resistance to PIs decreased among PI-exposed patients (71% to 46%, P = 0.010) as exposure to ritonavir-boosted PIs increased (6% to 81%, P < 0.001). Non-significant declines were observed in resistance to NRTIs among NRTI-exposed (82% to 67%), and triple-class-resistance among TCE patients (66% to 41%), but not to NNRTIs among NNRTI-exposed. Conclusions. HIV resistance was common but declined in HIV isolates from subgroups of ARV-experienced HOPS patients during 1999–2008. Resistance to PIs among PI-exposed patients decreased, possibly due to increased representation of patients whose only PI exposures were to boosted PIs. PMID:22611484

  8. It is time to consider third-line options in antiretroviral-experienced paediatric patients?

    2011-01-01

    Background The historic use of full-dose ritonavir as part of an unboosted protease inhibitor (PI)-based antiretroviral therapy regimen in some South African children contributes to the frequent accumulation of major PI resistance mutations. Methods In order to describe the prevalence of major PI resistance in children failing antiretroviral therapy and to investigate the clinical, immunological and virological outcomes in children with PI resistance, we conducted a cross-sectional study, with a nested case series, following up those children with major PI resistance. The setting was public health sector antiretroviral clinics in the Western Cape province of South Africa, and the subjects were children failing antiretroviral therapy. The following outcome measures were investigated: CD4 count, viral load and resistance mutations. Results Fourteen (17%) of 82 patients, referred from tertiary hospitals, had major PI resistance. All these patients were exposed to regimens that included ritonavir as a single PI. Immune reconstitution and clinical benefit were achieved when using a lopinavir/ritonavir-based treatment regimen in these children with prior PI resistance. At first HIV-1 viral load follow up after initial resistance testing (n = 11), only one patient had a viral load of less than 400 copies/ml; at a subsequent follow up (n = 9), the viral loads of five patients were less than 400 copies/ml. Patients retained on LPV/r had lower viral loads than those switched to a non-nucleoside reverse transcriptase inhibitor (NNRTI). However, two of three patients with follow-up resistance tests accumulated additional PI resistance. Conclusions In children with pre-existing PI resistance, although initially effective, the long-term durability of a lopinavir/ritonavir-based treatment regimen can be compromised by the accumulation of resistance mutations. Furthermore, a second-line NNRTI regimen is often not durable in these patients. As genotypic resistance testing and third

    A 49-year-old female with a history of several neurosurgical and otolaryngologic procedures for occipital meningioma and cerebrospinal fluid leaks was diagnosed with pneumocephalus after a one hour flight on a domestic jet airliner. Despite multiple operations, the air appeared to enter the cranium through a weak portion of the skull base due to the low atmospheric pressure in the cabin. The intracranial air was absorbed with conservative management. The patient was recommended not to fly before a definite diagnostic work up and a sealing procedure for the cerebrospinal fluid leak site had been performed. Recent advances in aviation technology have enabled many people to travel by air, including individuals with medical conditions. Low cabin pressure is not dangerous to healthy individuals; however, practicing consultant neurosurgeons should understand the cabin environment and prepare high risk patients for safe air travel.

    Objective Survivors of the acute respiratory distress syndrome (ARDS), a systemic critical illness, often report poor quality of life based on responses to standardized questionnaires. However, the experiences of ARDS survivors have not been reported. Our objective was to characterize the effects of critical illness in the daily lives and functioning of ARDS survivors. Design, Setting, and Patients We recruited consecutively 31 ARDS survivors and their informal caregivers from medical and surgical intensive care units of an academic medical center and a community hospital. Eight patients died before completing interviews. We conducted semi-structured interviews with 23 ARDS survivors and 24 caregivers three to nine months after ICU admission, stopping enrollment after thematic saturation was reached. Transcripts were analyzed using Colaizzi’s qualitative methodology to identify significant ways in which survivors’ critical illness experience impacted their lives. Measurements and Main Results Participants related five key elements of experience as survivors of ARDS: pervasive memories of critical care, day to day impact of new disability, critical illness defining the sense of self, relationship strain and change, and ability to cope with disability. Survivors described remarkable disability that persisted for months. Caregivers’ interviews revealed substantial strain from caregiving responsibilities, as well as frequent symptom minimization by patients. Conclusions The diverse and unique experiences of ARDS survivors reflect the global impact of severe critical illness. We have identified symptom domains important to ARDS patients that are not well represented in existing health outcomes measures. These insights may aid the development of targeted interventions to enhance recovery and return of function after ARDS. PMID:19865004

    Humour is an integral part of everyday life and therefore a component of the care and treatment of elderly patients in the modern health care. This article deals with the role of humour in aged nursing from the perspective of the nursing home residents. It also describes some preliminary results of our study on the meaning of humour to professional nurses. The chief motivation for the study is to provide a deeper understanding of humour as a part of aged nursing and as a 'phenomenon', which should also help us in the continuing challenge to improve the quality of nursing care. In this study the qualitative approach was used because the focus of interest was on an issue that has received only little attention in earlier research. The research material consists of data from patients and nurses. The data were collected via interviews and essay-type responses. The data obtained were analysed using the qualitative method of content analysis. In the light of our findings here, humour can be described as a joie de vivre which manifests itself in human interaction in the form of fun, jocularity and laughter. The assumption is supported by earlier research results which indicated that humour is an individual and personal matter and, in aged nursing care it is also very much a context-bound phenomenon. Humour makes it easier for some of the elderly patients to experience a positive, human relationship with the nurse. According to the results it seems to us that research should be continued and intensified into the role and use of humour in elderly people's everyday life and particularly in gerontological nursing care.

    The use of nurse practitioners (NPs) is one way to address the shortage of physician primary care providers. NP training programs and the number of practicing NPs have increased in the past two decades. However, regulations limiting their scope of practice vary greatly by state. We assessed the impact of state regulations on the increase in care provided by NPs in the United States, using a 5 percent national sample of Medicare beneficiaries. We found that between 1998 and 2010 the number of Medicare patients receiving care from NPs increased fifteenfold. By 2010 states with the least restrictive regulations of NP practice had a 2.5-fold greater likelihood of patients’ receiving their primary care from NPs than did the most restrictive states. Relaxing state restrictions on NP practice should increase the use of NPs as primary care providers, which in turn would reduce the current national shortage of primary care providers. PMID:23836739

    The elevated prevalence of neuropsychiatric symptoms and disorders among patients with multiple sclerosis (MS) is well recognized, as are potential neuropsychiatric side effects of treatment with corticosteroids. Both methylprednisolone (MP) and repository corticotropin injection (HP Acthar® gel) have demonstrated efficacy in reducing short-term disability after exacerbations of MS. Although historical data are limited, repository corticotropin injection has not generally been associated with detrimental neuropsychiatric effects. We describe six cases of patients with relapsing-remitting MS who had previously experienced detrimental mood changes with MP treatment. Some of these patients had previous histories of mood disorders or other neuropsychiatric symptoms prior to MS diagnosis. All six patients were subsequently treated with repository corticotropin injection for MS exacerbations and each demonstrated improvements in MS symptoms. This clinical experience suggests that repository corticotropin injection should be considered as an alternative for patients who do not tolerate corticosteroids or have difficulties associated with intravenous medication. Furthermore, the rate of neuropsychiatric side effects observed in these patients was low. These observations support repository corticotropin injection as a viable alternative for the treatment of acute exacerbations of MS, particularly in patients who have a history of neuropsychiatric disorders or symptoms either independently or in response to MP treatment. In reviewing both the published data and our own clinical experience regarding potential neuropsychiatric adverse events with treatment for MS exacerbations, we hope to stimulate further research into the potential efficacy and safety of repository corticotropin injection among patients with some form of neuropsychiatric complications that must be considered when establishing a treatment plan for MS.

    Background: Patients with psychotic disorders who experienced childhood trauma show more social dysfunction than patients without traumatic experiences. However, this may not hold for all patients with traumatic experiences. Little is known about the potential compensating role of Five-Factor Model personality traits within this group, despite their strong predictive value for social functioning and well-being in the general population. Methods: Our sample consisted of 195 patients with psychotic disorders (74% diagnosed with schizophrenia) and 132 controls. Cluster analyses were conducted to identify and validate distinct personality profiles. General linear model analyses were conducted to examine whether patients with different profiles differed in social functioning and quality of life (QoL), while controlling for possible confounders. Mediation models were tested to assess potential causal links. Results: In general, patients with higher levels of self-reported traumatic experiences (PT+) showed lower QoL and more social withdrawal compared with patients with lower traumatic experiences (PT−). Two clusters reflecting personality profiles were identified. PT+ with the first profile (lower neuroticism and higher extraversion, openness, agreeableness, and conscientiousness) presented higher levels of QoL and better social functioning in several areas, including less withdrawal, compared with both PT+ and PT− with the second profile. PT+ and PT− with the first personality profile did not differ in QoL and social functioning. Mediation analyses suggested that personality traits mediate the relation between traumatic experiences and QoL and social withdrawal. Conclusions: Our findings indicate that personality may “buffer” the impact of childhood traumatic experiences on functional outcome in patients with psychotic disorders. PMID:24771304

    Context As with care giving and rehabilitation in chronic illnesses, the concern with traumatic brain injury (TBI), particularly with diffuse axonal injury (DAI), is that the caregivers are so overwhelmingly involved in caring and rehabilitation of the victim that in the process they become traumatized themselves. This review intends to shed light on the hidden and silent trauma sustained by the caregivers of severe brain injury survivors. Motor vehicle accident (MVA) is the highest contributor of TBI or DAI. The essence of trauma is the infliction of pain and suffering and having to bear the pain (i.e. by the TBI survivor) and the burden of having to take care and manage and rehabilitate the TBI survivor (i.e. by the TBI caregiver). Moreover many caregivers are not trained for their care giving task, thus compounding the stress of care giving and rehabilitating patients. Most research on TBI including DAI, focus on the survivors and not on the caregivers. TBI injury and its effects and impacts remain the core question of most studies, which are largely based on the quantitative approach. Evidence Acquisition Qualitative research can better assess human sufferings such as in the case of DAI trauma. While quantitative research can measure many psychometric parameters to assess some aspects of trauma conditions, qualitative research is able to fully reveal the meaning, ramification and experience of TBI trauma. Both care giving and rehabilitation are overwhelmingly demanding; hence , they may complicate the caregivers’ stress. However, some positive outcomes also exist. Results Caregivers involved in caring and rehabilitation of TBI victims may become mentally traumatized. Posttraumatic recovery of the TBI survivor can enhance the entire family’s closeness and bonding as well as improve the mental status of the caregiver. Conclusions A long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of

    Objective Dementia is a major public health problem. More and more patients with dementia are being admitted to acute care hospitals for treatment of comorbidities. Issues associated with care of patients with dementia in acute care hospitals have not been adequately clarified. This study aimed to explore the challenges nurses face in providing care to patients with dementia in acute care hospitals in Japan. Methods This was a qualitative study using focus group interviews (FGIs). The setting was six acute hospitals with surgical and medical wards in the western region of Japan. Participants were nurses in surgical and internal medicine wards, excluding intensive care units. Nurses with less than 3 years working experience, those without experience in dementia patient care in their currently assigned ward, and head nurses were excluded from participation. FGIs were used to collect data from February to December 2008. Interviews were scheduled for 1–1.5 h. The qualitative synthesis method was used for data analysis. Results In total, 50 nurses with an average experience of 9.8 years participated. Eight focus groups were formed. Issues in administering care to patients with dementia at acute care hospitals were divided into seven groups. Three of these groups, that is, problematic patient behaviors, recurrent problem, and problems affecting many people equally, interact to result in a burdensome cycle. This cycle is exacerbated by lack of nursing experience and lack of organization in hospitals. In coping with this cycle, the nurses develop protection plans for themselves and for the hospital. Conclusions The two main issues experienced by nurses while administering care to patients with dementia in acute care hospitals were as follows: (a) the various problems and difficulties faced by nurses were interactive and caused a burdensome cycle, and (b) nurses do their best to adapt to these conditions despite feeling conflicted.

    In the terminal phase of life, some cancer patients have problems eating. Caregivers then have to decide whether or not to provide the patients with food by artificial means. Taped interviews concerning the treatment of terminally ill, mentally alert, old cancer patients who refuse food were conducted with 20 registered nurses who were regarded as "experienced and good nurses." Not one of these nurses considered using force or violence against the patients. It seemed that the question about whether to feed the patient was not as urgent as the question of whether to accept active euthanasia. The interviewees seemed quite certain about how they would treat the patient in different circumstances, but found it difficult to justify their judgements. Several stressed the importance of their personal experience with dying persons, and thought that one should act according to the Golden Rule. PMID:2512007

    The early integration of specialist palliative care has been shown to benefit the quality of life of patients with advanced cancer. In order to explore whether other seriously ill people and people at even earlier phases would also benefit from early palliative care, we conducted 18 qualitative interviews with people having cancer, chronic obstructive lung disease, heart failure, or dementia at different phases of the illness trajectory about how they experienced care needs related to their disease from diagnosis onward. Respondents experienced needs within the different domains of palliative care at different stages of the illness and different illness types or duration of the illness. This study contributes to the understanding of primary care needs of patients for whom palliative care (not necessarily specialized palliative care) could be beneficial. PMID:25852203

    Objectives The study aims to inform potential cost-effectiveness analysis of hypertension management in Vietnam by providing utilities and predictors of utilities in patients with hypertension. Methods Hypertensive patients up to 80 years old visiting the hospital were invited to participate in a survey using Quality Metric’s Short-form 36v2TM translated into Vietnamese. Health-state utilities were estimated by applying a previously published algorithm. Results The mean utility of the 691 patients interviewed was 0.73. Controlling for age, sex, blood pressure (BP) stage, and history of stroke, the utilities in older patients were lower than those in younger ones, and statistically significantly different between the extremes of youngest and oldest groups (p = 0.03). Utility in males was higher than in females (p = 0.002). As expected, patients with a history of stroke appeared to exhibit lower utilities than patients without such history, but the difference was not statistically significant (p = 0.73). Patients with more than three comorbidities did have lower utilities than patients without comorbidity (p = 0.01). Conclusions Health-state utilities found among hypertensive patients in Vietnam were similar to those found in other international studies. It is suggested that lower of health-state utilities exist among those patients who were older, female or had more than three comorbidities in comparison with respective reference groups. However, further research for confirmation is required. The data from this study provide a potential reference on health-state utilities of hypertensive patients in Vietnam as an input for future cost-effectiveness analysis of interventions. Also, it may serve as a reference for other similar populations, especially in the context of similar environments in low income countries. PMID:26506444

    Purpose Patients with a bipolar I disorder (BD-I) manic episode meeting the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), criteria for “with mixed features” have a high incidence of suicide attempts and of anxiety, irritability, and agitation (AIA) symptoms. The aim of this analysis was to explore the relationship between suicidality and AIA symptoms in patients with BD-I experiencing mania with depressive symptoms, using data from a previous naturalistic study. Patients and methods Psychiatrists completed an online questionnaire about their adult patients who had a current BD-I manic episode. Questions covered the DSM-5 “with mixed features” specifier, the severity of AIA symptoms, the frequency and controllability of suicidal ideation, and the number of suicide attempts. Results Of 1,035 patients with BD-I mania who were included in the analyses, 348 (33.6%) met the criteria for the DSM-5 “with mixed features” specifier (three or more depressive symptoms). These patients were further stratified according to the severity of their AIA symptoms: “mild AIA” (zero or one AIA symptom above a severity threshold; 105 patients) or “severe AIA” (all three AIA symptoms above a severity threshold; 167 patients). A greater incidence of suicidal ideation was observed in the severe AIA group (71.9%) than in the mild AIA group (47.6%). Twice as many patients had easily controlled suicidal ideation than difficult-to-control suicidal ideation in both subgroups. The mean number of suicide attempts was higher in the severe AIA group than in the mild AIA group, during the current episode (0.84 vs 0.34 attempts, respectively; P<0.05) and over the patient’s lifetime (1.56 vs 1.04 attempts, respectively). Conclusion The high risk of suicide among BD-I mania patients with depressive symptoms is further increased when they experience severe AIA symptoms. Recognizing AIA symptoms in BD-I mania could provide a means of identifying

    2014-01-01

    Background Chronic angina is a profoundly symptomatic disease. We evaluated the relationship between angina frequency and health utility. Methods We used data from stable angina patients reporting ≥3 attacks/week enrolled in the Efficacy of Ranolazine in Chronic Angina (ERICA) trial. Angina frequency was classified using the Seattle Angina Questionnaire angina frequency (SAQAF) domain into no (100); monthly (61-99); weekly (31-60); and daily (0-30) angina. EuroQol (EQ)-5D health utility scores were derived from SAQ data using two mapping equations. Median EQ-5D utility scores for each SAQAF classification after the 6-week trial period were calculated (reported as: Equation 1/Equation 2). Changes in EQ-5D utility scores from baseline to end-of-trial for patients achieving and not achieving a ≥20-point improvement in SAQAF score and improving and not improving ≥1 SAQAF classification were compared. Results Median EQ-5D utility scores (n = 548) were 0.68/0.60. Compared to patients reporting no angina symptoms (n = 28; 0.89/0.87) patients reporting monthly (n = 188; 0.80/0.76), weekly (n = 283; 0.72/0.65) and daily (n = 49; 0.65/0.54) symptoms had poorer health utility (p < 0.001 for both equations). Patients improving ≥1SAQAF classification (n = 254/541, 47%) experienced a median 0.05/0.07 greater improvement in EQ-5D health utility compared to those not improving ≥1 classification (p < 0.001 for both equations). Patients improving ≥20-points on the SAQAF (n = 355/541, 66%) experienced a median 0.06/0.07 greater improvement in health utility compared to those not achieving a ≥20-point improvement (p < 0.001 for both). Conclusions Chronic angina patient health utility decreases as angina frequency increases. Patients reporting clinically important improvement in angina frequency experience a tangible improvement in health utility. Clinical trial registration NCT00091429 PMID:24628859

    Background. Colorectal cancer is becoming a chronic condition. This has significant implications for the delivery of health care and implies the involvement of a range of health care professionals (HCPs) from different settings to ensure the needed quality and continuity of care. Objectives. To explore the challenges that patients and HCPs experience in the course of colorectal cancer care and the perceived consequences caused by these challenges. Methods. Ten semi-structured focus groups were conducted including patients receiving treatment for colorectal cancer, representatives of patient support groups, physicians and other non-physician HCPs from different health care settings. Participants were asked to share their experiences regarding colorectal cancer care. All data were audio- and videotaped, transcribed verbatim and thematically analysed using qualitative content analysis. Results. Patients and HCPs (total N = 47) experienced collaboration and communication as well as exchange of information between HCPs as challenging. Particularly communication and information exchange with GPs appeared to be lacking. The difficulties identified restricted a well-working coordination of care and seemed to cause inappropriate health care. Conclusion. Colorectal cancer care seems to require an effective, well-working collaboration and communication between the different HCPs involved ensuring the best possible care to suit patients’ individual needs. However, the perceived challenges and consequences of our participants seem to restrict the delivery of the needed quality of care. Therefore, it seems crucial (i) to include all HCPs involved, especially the GP, (ii) to support an efficient and standardized exchange of health-related information and (iii) to focus on the patients’ entire pathway of care.

    Given the increasing popularity of a hospice inpatient/residential facility (HIRF) among hospice patients and their family members, examining who uses HIRFs has been of increasing importance. Using the 2007 National Home and Hospice Care Survey (NHHCS), we found that about 14% of hospice patients received care in a HIRF in 2007. Characteristics of patients associated with HIRF use largely match the industry norm for a general inpatient level of care, and include: having no caregiver, or having an incapable caregiver; having imminent death; and being directly admitted to a hospice after discharge from a hospital. Given a recent stricter enforcement of reimbursement rules, however, we call for close monitoring of any change in the number of HIRF beds—particularly in rural and low-income urban areas.

    Drop seizures are especially problematic in patients with Lennox-Gastaut syndrome (LGS) because of their potential for serious injury. In this post hoc analysis of phase 3 OV-1012 data, a medical review was conducted of seizure-related injuries based on Medical Dictionary for Regulatory Activities (MedDRA) preferred terms from all adverse event (AE) listings. Patients receiving clobazam experienced fewer seizure-related injuries than those receiving placebo (8.9% all clobazam dosages vs. 27.1% placebo, p ≤ 0.05). Significant differences in the rates of seizure-related injuries were observed for the medium- and high-dosage clobazam treatment groups (4.8% and 10.2%, respectively, p ≤ 0.05). A total of 50 of 53 AEs considered seizure-related were mild or moderate in intensity; 3 severe AEs occurred in the placebo group (fall, contusion, and jaw fracture). A single serious AE (jaw fracture, which required hospitalization and surgery) occurred in a placebo-treated patient. Most injuries resolved by the end of the study. This analysis indicates that the reduction in drop-seizure frequency achieved with clobazam provides a clinically meaningful benefit, a reduced likelihood of experiencing seizure-related injuries.

    Abstract Atazanavir-based regimens have established efficacy and safety in both antiretroviral (ARV)-naive and -experienced patients. However, data evaluating effectiveness beyond 2 years is sparse. Therefore, we assessed the long-term outcomes of ritonavir-boosted atazanavir (ATV/r)-containing regimens in ARV-experienced patients in a clinical setting in a noncomparative, retrospective, observational study collecting data from three European HIV databases on ARV-experienced adults with HIV-1 infection starting an ATV/r-based regimen. Data were extracted every 6 months (maximum follow-up 5 years). Primary outcome was the proportion of patients remaining on ATV/r by baseline HIV-1 RNA (<500 or ≥500 copies/ml). Secondary outcomes included time to virologic failure, reasons for discontinuation, and long-term safety profile. The duration of treatment and time to virologic failure were analyzed using the Kaplan–Meier method. Data were analyzed for 1,294 ARV-experienced patients (male 74%; mean ART exposure 5.7 years). After 3 years, 56% (95% CI: 52%, 60%) of patients with baseline HIV-1 RNA <500 copies/ml and 53% (95% CI: 49%, 58%) of those with HIV-1 RNA ≥500 copies/ml remained on ATV/r. After 3 years, 75% (95% CI: 69%, 80%) of patients with baseline HIV-1 RNA <50 copies/ml remained suppressed and 51% (95% CI: 47%, 55%) of those with baseline HIV-1 RNA ≥50 copies/ml achieved and maintained virologic suppression. Although adverse events (AEs) were the main known reason for discontinuation, no unexpected AEs were observed. In a real-life setting ATV/r-based regimens demonstrated sustained virologic suppression in ARV-experienced patients. After long-term therapy the majority of patients remained on treatment and no unexpected AEs were observed. PMID:23016535

    Several randomized trials and decision analysis models have found that remote monitoring may reduce health care utilization and expenditures in patients with cardiac implantable electronic devices (CIEDs), compared with in-office monitoring. However, little is known about the generalizability of these findings to unselected populations in clinical practice. To compare health care utilization and expenditures associated with remote monitoring and in-office monitoring in patients with CIEDs, we used Truven Health MarketScan Commercial Claims and Medicare Supplemental Databases. We selected patients newly implanted with an implantable cardioverter defibrillators (ICD), cardiac resynchronization therapy defibrillator (CRT-D), or permanent pacemaker (PPM), in 2009, who had continuous health plan enrollment 2 years after implantation. Generalized linear models and propensity score matching were used to adjust for confounders and estimate differences in health care utilization and expenditures in patients with remote or in-office monitoring. We identified 1,127; 427; and 1,295 pairs of patients with a similar propensity for receiving an ICD, CRT-D, or PPM, respectively. Remotely monitored patients with ICDs experienced fewer emergency department visits resulting in discharge (p = 0.050). Remote monitoring was associated with lower health care expenditures in office visits among patients with PPMs (p = 0.025) and CRT-Ds (p = 0.006) and lower total inpatient and outpatient expenditures in patients with ICDs (p <0.0001). In conclusion, remote monitoring of patients with CIEDs may be associated with reductions in health care utilization and expenditures compared with exclusive in-office care. PMID:26996767

    Background Successful scale-up in the use of malaria rapid diagnostic tests (RDTs) requires that patients accept testing and treatment based on RDT results and that healthcare providers treat according to test results. Patient-provider communication is a key component of quality care, and leads to improved patient satisfaction, higher adherence to treatment and better health outcomes. Voiced or perceived patient expectations are also known to influence treatment decision-making among healthcare providers. While there has been a growth in literature on provider practices around rapid testing for malaria, there has been little analysis of inter-personal communication around the testing process. We investigated how healthcare providers and patients interact and engage throughout the diagnostic and treatment process, and how the testing service is experienced by patients in practice. Methods This research was conducted alongside a larger study which explored determinants of provider treatment decision-making following negative RDT results in a rural district (Kibaale) in mid-western Uganda, ten months after RDT introduction. Fifty-five patients presenting with fever were observed during routine outpatient visits at 12 low-level public health facilities. Observation captured communication practices relating to test purpose, results, diagnosis and treatment. All observed patients or caregivers were immediately followed up with in-depth interview. Analysis followed the ‘framework’ approach. A summative approach was also used to analyse observation data. Results Providers failed to consistently communicate the reasons for carrying out the test, and particularly to RDT-negative patients, a diagnostic outcome or the meaning of test results, also leading to confusion over what the test can detect. Patients appeared to value testing, but were frustrated by the lack of communication on outcomes. RDT-negative patients were dissatisfied by the absence of information on an

    Background. An exploratory subanalysis of the ODIN trial was performed to evaluate the efficacy of darunavir/ritonavir (DRV/r) 800/100 mg OD versus 600/100 mg BID in patients who were NNRTI-experienced but PI-naïve. Methods. ODIN was a phase III, 48-week study comparing DRV/r OD versus BID in 590 treatment-experienced patients with no DRV resistance-associated mutations (RAMs) at screening. Patients received DRV/r 800/100 mg OD or DRV/r 600/100 mg BID plus ≥2 NRTIs. Of the 590 patients randomized, 272 (46%) were NNRTI-experienced but PI-naïve. Results. Overall, 272 patients received DRV/r OD (n = 135) or BID (n = 137) plus ≥2 optimised NRTIs. The mean age was 39 years; 35% were female; 27% were Black, 24% Caucasian, 26% Oriental/Asian, and 23% other races; 17% were recruited in South Africa; and 48% had non-B HIV-1 subtypes. Mean baseline plasma HIV-1 RNA load was 4.10 log10⁡ copies/mL; median CD4 cell count was 258 cells/μL. At week 48, 111/135 (82%) of DRV/r OD and 109/137 (80%) of DRV/r BID patients achieved an HIV-1 RNA load <50 copies/mL. No patient developed primary PI RAMs. Conclusion. DRV/r 800/100 mg OD in combination with ≥2 optimised NRTIs led to virological suppression <50 copies/mL in 82% of NNRTI-experienced, PI-naïve patients by week 48. PMID:26357568

    OBJECTIVES/HYPOTHESIS The primary study goal was to measure health state utility values in patients with chronic rhinosinusitis (CRS) before and after undergoing endoscopic sinus surgery (ESS). A secondary goal was to assess the meaning of these values by comparing them with other chronic disease processes and currently available medical or surgical treatments. STUDY DESIGN Prospective, observational cohort study METHODS Adults with CRS were enrolled after electing ESS and observed over a 5-year period. Baseline demographic and medical comorbidities were recorded for each patient, as well as computed tomography (CT), endoscopy, olfaction, and disease-specific quality of life scores. Utility values were derived using the Short-Form 6D (SF-6D) at baseline and again after surgery. RESULTS The mean SF-6D utility value for the baseline health state of all patients with CRS (n=232) was 0.65 (95% CI: 0.63–0.66). Baseline utility values correlated with disease-specific QOL as measured by the Rhinosinusitis Disability Index (RSDI) (r=−0.660; P<0.001), but not baseline CT, endoscopy, or olfactory scores. Follow-up utility values (≥6 months) after ESS improved by 0.087 (95% CI: 0.06–0.12; P<0.001) in patients with no history of sinus surgery and 0.062 (95% CI: 0.04–0.09; P<0.001) in those undergoing a revision procedure. CONCLUSIONS Patients with CRS who failed medical therapy and elected to undergo ESS report health state utility values which are significantly lower than the United States population norm. Utility values showed improvement after ESS which was statistically and clinically significant. These results provide the initial data necessary for formal cost-effectiveness analyses incorporating ESS. PMID:22034223

    OBJECTIVE To examine the influence of utilization review and denial of specialty referrals on patient satisfaction with overall medical care, willingness to recommend one’s physician group to a friend, and desire to disenroll from the health plan. DESIGN Two cross-sectional questionnaires: one of physician groups and one of patient satisfaction. SETTING Eighty-eight capitated physician groups in California. PARTICIPANTS Participants were 11,710 patients enrolled in a large California network-model HMO in 1993 who received care in one of the 88 physician groups. MEASUREMENTS AND MAIN RESULTS Our main measures were how groups conducted utilization review for specialty referrals and tests, patient-reported denial of specialty referrals, and patient satisfaction with overall medical care. Patients in groups that required preauthorization for access to many types of specialists were significantly (p≤ .001) less satisfied than patients in groups that had few preauthorization requirements, even after adjusting for patient and other group characteristics. Patients who had wanted to see a specialist in the previous year but did not see one were significantly less satisfied than those who had wanted to see a specialist and actually saw one (p < .001). In addition, patients who did not see a specialist when desired were more likely to want to disenroll from the health plan than patients who saw the specialist (40% vs 18%, p≤ .001) and more likely not to recommend their group to a friend (38% vs 13%, p≤ .001). CONCLUSIONS Policies that limited direct access to specialists, and especially denial of patient-desired referrals, were associated with significantly lower patient satisfaction, increased desire to disenroll, and lower likelihood of recommending the group to a friend. Health plans and physician groups need to take these factors into account when designing strategies to reduce specialty care use. PMID:10337038

    Purpose: Estimating the cost-effectiveness of whole-brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS), including Gamma Knife radiosurgery (GKRS), requires the quantitative measurement of patients’ health states after treatment. We sought to quantify individuals’ preferences for the relevant health states after WBRT or GKRS for brain metastases on a 0 to 1 scale, where 1 is perfect health and 0 is death. Methods: We prospectively measured utilities in patients with brain metastases evaluated at Yale for consideration of WBRT and/or GKRS, as well as oncology nurses who had cared for patients with brain metastases before and after WBRT or GKRS, using the Standard Gamble (SG) technique. Demographic information was also collected. Nonparametric tests were used to compare potential differences in utility values and for subgroups based on demographic characteristics. Results: There were 24 patients and 31 nurses who completed the study between December 2013 and May 2015. Median utilities ranged from 0.85 for the status-post (S/P) GKRS state to 0.25 (for neurologic dying). The median utility of being S/P WBRT was 0.70 compared to 0.85 S/P GKRS (p < 0.001). The cognitive decline from WBRT was associated with a notably low utility score of 0.30. There were no statistically significant differences between patients’ and nurses’ median utility scores. Conclusions: These SG utilities provide unique insights into brain metastases-related health states from the patient and provider perspective. As perceived by individuals with direct knowledge of the health states in question, WBRT has a significantly lower utility compared to GKRS. Cognitive decline following WBRT is associated with significant perceived reduction in quality of life. Differences in the relative importance of overall survival and quality of life with treatment existed between patients with different stages of disease. These utilities can be used to calculate quality-adjusted life

    This initiative utilized a collaborative learning approach to increase knowledge and experience in process improvement and systems thinking while targeting improved patient flow in seven radiology modalities. Teams showed improvements in their project metrics and collectively streamlined the flow for 530 patients per day by improving patient lead time, wait time, and first case on-time start rates. In a post-project survey of 50 project team members, 82% stated they had more effective solutions as a result of the process improvement methodology, 84% stated they will be able to utilize the process improvement tools again in the future, and 98% would recommend participating in another project to a colleague.

    Background Organizational context plays a central role in shaping the use of research by healthcare professionals. The largest group of professionals employed in healthcare organizations is nurses, putting them in a position to influence patient and system outcomes significantly. However, investigators have often limited their study on the determinants of research use to individual factors over organizational or contextual factors. Methods The purpose of this study was to examine the determinants of research use among nurses working in acute care hospitals, with an emphasis on identifying contextual determinants of research use. A comparative ethnographic case study design was used to examine seven patient care units (two adult and five pediatric units) in four hospitals in two Canadian provinces (Ontario and Alberta). Data were collected over a six-month period by means of quantitative and qualitative approaches using an array of instruments and extensive fieldwork. The patient care unit was the unit of analysis. Drawing on the quantitative data and using correspondence analysis, relationships between various factors were mapped using the coefficient of variation. Results Units with the highest mean research utilization scores clustered together on factors such as nurse critical thinking dispositions, unit culture (as measured by work creativity, work efficiency, questioning behavior, co-worker support, and the importance nurses place on access to continuing education), environmental complexity (as measured by changing patient acuity and re-sequencing of work), and nurses' attitudes towards research. Units with moderate research utilization clustered on organizational support, belief suspension, and intent to use research. Higher nursing workloads and lack of people support clustered more closely to units with the lowest research utilization scores. Conclusion Modifiable characteristics of organizational context at the patient care unit level influences research

    The management and treatment of adult asthma has been associated with utilization of health services. Objectives: First, to investigate the likelihood of health service utilization, including primary care, emergency department, and hospital stays, among persons diagnosed with an asthma condition relative to those that do not have an asthma condition. Second, to examine the likelihood of poor physical health among asthma respondents relative to those that do not have an asthma condition. Third, to demonstrate that these relationships vary with frequency of utilization. Fourth, to discuss the magnitude of differences in frequent utilization between asthma and non-asthma respondents. Data Source: Data is derived from a random, stratified sampling of Hampton Roads adults, 18 years and older (n = 1678). Study Design: Study participants are interviewed to identify asthma diagnosis, access to primary care, frequency of emergency department utilization, hospital admissions, and days of poor physical health. Odds-ratios establish relationships with the covariates on the outcome variable. Findings: Those with asthma are found more likely (OR 1.50, 95% CI 1.05–2.15) to report poor physical health relative to non-asthma study participants. Further, asthma respondents are found more likely (OR 4.23, 95% CI 1.56–11.69) to frequently utilize primary care that may be associated with the management of the condition and are also more likely to utilize treatment services, such as the emergency department (OR 1.87, 95% CI 1.32–2.65) and hospitalization (OR 2.21, 95% CI 1.39–3.50), associated with acute and episodic care. Further, it is a novel finding that these likelihoods increase with frequency of utilization for emergency department visits and hospital stays. Conclusion: Continuity in care and better management of the diseases may result in less demand for emergency department services and hospitalization. Health care systems need to recognize that asthma patients are

    Chronic stable angina is a debilitating illness affecting at least 6.6 million US residents. Despite being optimally treated by pharmacotherapy and revascularization up to 26% of patients still experience angina. Diabetes mellitus is a common co-morbid condition in angina patients. Several new investigational medications are being tested for chronic angina. Advances in understanding of myocardial ischemia have prompted evaluation of a number of new antianginal strategies. In this review we discuss the utility of ranolazine, a recently approved novel antianginal agent and its efficacy in the diabetic patient population. In addition to its antianginal action in diabetic patients with chronic angina, ranolazine may have favorable effects on glycated hemoglobin levels. PMID:19065998

    2016-01-01

    Hemophilia is a serious rare disease that requires continuous management and treatment for which the medicine is costly at the annual average of 100 million KRW for an individual. The aim of this study was to investigate trends in the utilization of coagulation factor (CF) used for hemophilia treatment using the National Health Insurance database from 2010 to 2013 in Korea and compare the utilization of CF with other countries. The consumption of CF per capita (IU) in Korea was not more than other countries with similar income to Korea. However, CF usage per patient IU was higher because the prevalence rate of hemophilia in Korea was lower than in other countries while the number of serious patients was much more. Therefore, it is difficult to say that the consumption of hemophilia medicine in Korea is higher than that in other countries. The consumption and cost of hemophilia medicine in Korea is likely to increase due to the increased utilization of expensive bypassing agents and the widespread use of prophylaxis for severe hemophilia. Even during the research period, it increased slightly and other countries show a similar trend. Thus, hemophilia patient management should accompany active monitoring on the health and cost outcomes of pharmaceutical treatment in the future. This study is expected to contribute to further insight into drug policies for other countries that face similar challenges with high price pharmaceuticals. PMID:26770035

    Objectives Clinical relevance of low-frequency HIV-1 variants carrying drug resistance associated mutations (DRMs) is still unclear. We aimed to study the prevalence of low-frequency DRMs, detected by Ultra-Deep Sequencing (UDS) before antiretroviral therapy (ART) and at virological failure (VF), in HIV-1 infected patients experiencing VF on first-line ART. Methods Twenty-nine ART-naive patients followed up in the ANRS-CO3 Aquitaine Cohort, having initiated ART between 2000 and 2009 and experiencing VF (2 plasma viral loads (VL) >500 copies/ml or one VL >1000 copies/ml) were included. Reverse transcriptase and protease DRMs were identified using Sanger sequencing (SS) and UDS at baseline (before ART initiation) and VF. Results Additional low-frequency variants with PI-, NNRTI- and NRTI-DRMs were found by UDS at baseline and VF, significantly increasing the number of detected DRMs by 1.35 fold (p<0.0001) compared to SS. These low-frequency DRMs modified ARV susceptibility predictions to the prescribed treatment for 1 patient at baseline, in whom low-frequency DRM was found at high frequency at VF, and 6 patients at VF. DRMs found at VF were rarely detected as low-frequency DRMs prior to treatment. The rare low-frequency NNRTI- and NRTI-DRMs detected at baseline that correlated with the prescribed treatment were most often found at high-frequency at VF. Conclusion Low frequency DRMs detected before ART initiation and at VF in patients experiencing VF on first-line ART can increase the overall burden of resistance to PI, NRTI and NNRTI.

    Apart from the BENCHMRK study, there are no large observational experiences describing the long-term efficacy and safety of rescue regimens for human immunodeficiency virus type 1 (HIV-1) infection. Antiretroviral-experienced patients with detectable viraemia starting a raltegravir (RAL)-based regimen between March 2007 and June 2009 were consecutively enrolled and followed for ≥4 years. Data were censored at Week 206 for homogeneity. Of 333 patients, 258 (77.5%) were still on RAL-based therapy at Week 206, and 241 had undetectable HIV-1 RNA (73% in intention-to-treat analysis). Of the 75 subjects who discontinued RAL therapy, 36 were lost to follow-up, 15 changed their regimen due to virological failure, 2 simplified their regimen stopping RAL, 9 stopped all antiretrovirals and 13 died. Overall, 100 subjects (30.0%) had at least one detectable viraemia, but only 32 (9.6%) had true viral failure. Seventeen patients continued their failing regimen. 'Blips' were experienced by 53 patients (15.9%), whilst 15 (4.5%) had confirmed viral rebound due to adherence issues and were re-suppressed upon treatment re-introduction. In a multivariate analysis of predictors of interruption or failure, each baseline HIV-1 RNA log10 increase was associated with an adjusted hazard ratio for failure of 1.6; having more than 13 previous treatment courses also emerged as a predictor. Overall, adverse events were rare (n=64), with 13 deaths. Tumours were mainly early events, often fatal (7/15), mainly non-Hodgkin's lymphomas (8), followed by hepatocarcinoma (2). RAL proved effective and well tolerated in this cohort, and few patients experienced viral failure after 4 years. PMID:24315315

    Background Acute coronary syndromes (ACS) have been associated with lower health utilities (HUs) compared with the general population. Given the prognostic improvements after ACS with the implementation of coronary angiography (eg, percutaneous coronary intervention (PCI)), contemporary HU values derived from patient-reported outcomes are needed. Methods We analysed data of 1882 patients with ACS 1 year after coronary angiography in a Swiss prospective cohort. We used the EuroQol five-dimensional questionnaire (EQ-5D) and visual analogue scale (VAS) to derive HU indexes. We estimated the effects of clinical factors on HU using a linear regression model and compared the observed HU with the average values of individuals of the same sex and age in the general population. Results Mean EQ-5D HU 1-year after coronary angiography for ACS was 0.82 (±0.16) and mean VAS was 0.77 (±0.18); 40.9% of participants exhibited the highest utility values. Compared with population controls, the mean EQ-5D HU was similar (expected mean 0.82, p=0.58) in patients with ACS, but the mean VAS was slightly lower (expected mean 0.79, p<0.001). Patients with ACS who are younger than 60 years had lower HU than the general population (<0.001). In patients with ACS, significant differences were found according to the gender, education and employment status, diabetes, obesity, heart failure, recurrent ischaemic or incident bleeding event and participation in cardiac rehabilitation (p<0.01). Conclusions At 1 year, patients with ACS with coronary angiography had HU indexes similar to a control population. Subgroup analyses based on patients' characteristics and further disease-specific instruments could provide better sensitivity for detecting smaller variations in health-related quality of life.

    Objective Whether therapeutic drug monitoring of protease inhibitors (PIs) improves outcomes in HIV-infected patients is controversial. We evaluated this strategy in a randomized, open-label clinical trial, using a normalized inhibitory quotient (NIQ), which incorporates drug exposure and viral drug resistance. NIQs≤1 may predict poor outcome and identify patients who could benefit from dose escalation. Design/Methods Eligible patients had a viral load ≥1,000 copies/mL on a failing regimen, and began a new PI-containing regimen at entry. All FDA-approved PIs available during study recruitment (June 2002-May 2006) were allowed. One-hundred-eighty-three participants with NIQ≤1, based on their week 2 PI trough concentration and pre-entry drug resistance test, were randomized at week 4 to standard of care (SOC) or PI dose escalation (TDM). The primary endpoint was change in log10 plasma HIV-1 RNA concentration from randomization to 20 weeks later. Results Ninety-one subjects were randomized to SOC, 92 to TDM. NIQs increased more in the TDM arm compared to SOC (+69% versus +25%, p=0.01). Despite this, TDM and SOC arms showed no difference in outcome (+0.09 versus +0.02 log10, p=0.17). In retrospective subgroup analyses, patients with less HIV resistance to their PIs benefited from TDM (p=0.002), as did black and Hispanic patients (p=0.035 and 0.05, respectively). Differences between black and white patients persisted when accounting for PI susceptibility. Conclusions There was no overall benefit of TDM.

    Background: Patients with relapsing–remitting multiple sclerosis (RRMS) may experience breakthrough disease despite effective interferon beta (IFNβ) therapy. Fludarabine (FLU) is a chemotherapeutic agent used in lymphoproliferative disorders that may be synergistic when combined with immunomodulatory therapy to control active multiple sclerosis (MS). Objective: The objective of this study was to explore the safety and tolerability of FLU versus monthly methylprednisolone (MP) in IFNβ-treated RRMS patients with breakthrough disease. Clinical and MRI effects of IFNβ-1a plus FLU were evaluated. Methods: Eighteen patients with breakthrough disease [⩾2 relapses over the prior year and ⩾1.0-point increase in Expanded Disability Status Scale (EDSS) score sustained for ⩾3 months] after >1 year of IFNβ therapy were enrolled in this prospective, open-label, randomized, proof-of-concept, pilot study. Patients received intravenous (IV) MP 1 g daily for 3 days and then were randomized to receive 3 monthly IV infusions of FLU 25 mg/m2 daily for 5 consecutive days (n = 10) or MP 1 g (n = 8). All patients maintained their intramuscular IFNβ-1a treatment throughout the study. Analyses explored safety signals and directional trends; this preliminary study was not powered to detect clinically meaningful differences. Results: Both combination treatments were safe and well tolerated, with all adverse events mild. Patients treated with IFNβ-1a plus FLU had similar relapse rates, EDSS scores, and MS Functional Composite scores, but significantly less acute corticosteroid use for on-study relapses and better responses on some MRI outcomes, versus patients treated with IFNβ-1a plus MP. Conclusions: Further study of FLU for breakthrough disease in patients with RRMS is warranted. PMID:27006698

    The harm associated with lung cancer treatment include perioperative morbidity and mortality and therapy-induced toxicities in various organs, including the heart and lungs. Optimal treatment therefore entails a need for risk assessment to weigh the probabilities of benefits versus harm. Exercise testing offers an opportunity to evaluate a patient's physical fitness/exercise capacity objectively. In lung cancer, it is most often used to risk-stratify patients undergoing evaluation for lung cancer resection. In recent years, its use outside this context has been described, including in nonsurgical candidates and lung cancer survivors. In this article we review the physiology of exercise testing and lung cancer. Then, we assess the utility of exercise testing in patients with lung cancer in four contexts (preoperative evaluation for lung cancer resection, after lung cancer resection, lung cancer prognosis, and assessment of efficiency of exercise training programs) after systematically identifying original studies involving the most common forms of exercise tests in this patient population: laboratory cardiopulmonary exercise testing and simple field testing with the 6-minute walk test, shuttle walk test, and/or stair-climbing test. Lastly, we propose a conceptual framework for risk assessment of patients with lung cancer who are being considered for therapy and identify areas for further studies in this patient population.

    Aim: The purpose of this study was to investigate continuity of care in the psychiatric healthcare system from the perspective of patients, including vulnerable groups such as immigrants and refugees. Method: The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes). Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Results: Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. Conclusions: The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups. PMID:25233017

    Capecitabine is a chemotherapeutic agent used in the treatment of metastatic colon cancer and metastatic breast cancer. It is metabolized into fluorouracil (5-FU) in the liver; hence, its mechanism of action is similar to that of 5-FU. Cardiac toxicity, although rarely seen, may be of concern in some patients. Although multiple hypotheses have been proposed for the mechanism of cardiotoxicity, coronary vasospasm is the most commonly accepted one, as patients usually present with chest pain resembling acute myocardial infarction. Electrocardiography may demonstrate ST-segment elevation, and cardiac biomarkers may be elevated. Cardiotoxicity with 5-FU has been reported widely. Capecitabine has been shown to be much less cardiotoxic compared to 5-FU, with only a handful of cases reporting cardiotoxicity with capecitabine. There are no cases reporting cardiotoxicity with both 5-FU and capecitabine in the same patient. In this case report, we present a patient with adverse cardiac effect with capecitabine whose previous 5-FU therapy was stopped due to cardiotoxicity. PMID:26875134

    Objectives Etravirine (ETR) was approved in France in September 2008 and is used in combination with a boosted protease inhibitor (bPI) and other anti-retrovirals (ART) in HIV-infected pre-treated patients. This study aimed to report in a real-life setting the efficacy and tolerability of ETR-based regimens and factors associated with virological response. Methods The study population included all treatment-experienced patients who initiated an ETR-based regimen between September 2008 and July 2013 from the French Dat'AIDS cohort. Analyses were performed in ART-experienced patients starting ETR after virological failure (VF) or as a maintenance therapy (MT), with or without bPI. Results A total of 2006 patients (VF, n = 1014 (51%); MT, n = 992 (49%)) were included. At M12, the proportion of patients with HIV RNA < 50 copies/ml was 71.7% (72.0% and 71.1% with or without bPI) in the VF group and 90.5% (85.0% and 92.3% with or without bPI) in the MT group, without significant differences regarding the use of bPI. ETR was discontinued in 8.8% of patients for adverse events in 23.9% of cases (21.5% in VF, 29.5% in MT), treatment failure in 15.2% (16.2% in VF, 7.4% in MT) or simplification in 5.4% (4.6% in VF, 7.4% in MT). In the VF group, factors associated with virological response were a longer duration of HIV infection (OR = 2.7; p < 0.001) and baseline HIV RNA < 5 log10 copies/mL (OR = 2.1; p = 0.002). Conclusion This study shows that in ART-experienced patients ETR is well tolerated with a high efficacy when combined with other active drugs, even when the regimen does not include a bPI.

    Background Dolutegravir is a powerful, well-tolerated integrase inhibitor with a high genetic barrier to resistance and may thus constitute the backbone of lightened regimens. Methods This was a monocentric, retrospective study. HIV-1-infected patients receiving dolutegravir as monotherapy (mDGV) or dual therapy (dDGV) were systematically identified. The primary outcome was the proportion of patients who maintained undetectable (<50 copies/mL) plasma HIV RNA [plasma viral load (PVL)]. Results We identified 21 patients on mDGV (50 mg/day) and 31 on dDGV (50 or 100 mg/day, with atazanavir ± ritonavir, n = 12; rilpivirine, n = 11; maraviroc, n = 3; lamivudine, n = 3; darunavir/ritonavir, n = 1; or abacavir, n = 1). All of the patients were treatment experienced and 48% had experienced at least one virological failure. The baseline characteristics were as follows (for the mDGV/dDGV patients, respectively): 5%/29% had a history of AIDS; the median (IQR) highest PVL was 4.5 (4.3–5.5)/5.3 (4.7–5.6) log copies/mL; the median (IQR) nadir CD4+ count was 310 (280–468)/199 (134–281) cells/mm3; 100% had undetectable PVL before the mDGV for a median (IQR) duration of 5.9 (3.5–9.9) years/81% had undetectable PVL before the dDGV for a median (IQR) duration of 3.7 (1.4–8.3) years; and the median (IQR) HIV DNA level was 2.7 (2.1–3.1)/2.9 (2.7–3) log copies/106 PBMCs. At the last follow-up visit, 100% and 97% of patients showed undetectable PVL following mDGV and dDGV, respectively [median (IQR) follow-up of 32 (29–45) and 50 (30–74) weeks, respectively]. Conclusions In our experience, dolutegravir-based lightened regimens provided a high proportion of viral suppression, even in highly treatment-experienced patients. PMID:26712907

    An important focus for meaningful use criteria is to engage patients in their care by allowing them online access to their health information, including test results. There has been little evaluation of such initiatives. Using a mixed methods analysis of electronic health record data, surveys, and qualitative interviews, we examined the impact of allowing patients to view their test results via patient portal in one large health system. Quantitative data were collected for new users and all users of the patient portal. Qualitative interviews occurred with patients who had received an HbA1c or abnormal Pap result. Survey participants were active patient portal users. Our main measures were patient portal usage, factors associated with viewing test results and utilizing care, and patient and provider experiences with patient portal and direct release. Usage data show 80% of all patient portal users viewed test results during the year. Of survey respondents, 82.7% noted test results to be a very useful feature and 70% agreed that patient portal has made their provider more accessible to them. Interviewed patients reported feeling they should have direct access to test results and identified the ability to monitor results over time and prepare prior to communicating with a provider as benefits. In interviews, both patients and physicians reported instances of test results leading to unnecessary patient anxiety. Both groups noted the benefits of results released with provider interpretation. Quantitative data showed patient utilization to increase with viewing test results online, but this effect is mitigated when results are manually released by physicians. Our findings demonstrate that patient portal access to test results was highly valued by patients and appeared to increase patient engagement. However, it may lead to patient anxiety and increase rates of patient visits. We discuss how such unintended consequences can be addressed and larger implications for

    Abstract We investigated the safety, efficacy, and impact of ribavirin and peginterferon dose reduction on complete early virologic response and sustained virologic response (SVR) to triple therapy with telaprevir in treatment-experienced patients with advanced liver fibrosis. Treatment was initiated for 211 patients who failed treatment with peginterferon and ribavirin, with bridging fibrosis (F3, n = 68) or cirrhosis (F4, n = 143), including 103 (49%) null-responders (NR), 30 (14%) partial responders (PR), and 78 (37%) relapsers (REL). Impaired liver function (ILF) platelets <100,000/mm3 or albumin <35 g/L were present in 40 patients. The distribution of hepatitis C virus subtypes was: 1a, 1b, or 1, with undetermined subtype for 10 (5%), 187 (89%), and 14 (6%) patients, respectively. Treatment was started with peginterferon alpha-2a or alpha-2b, ribavirin, and telaprevir at standard doses. The overall SVR24 rate was 56% and was lower in cirrhotic patients (NR: 35%, PR: 40%, and REL: 63%, respectively) than in patients with bridging fibrosis (NR: 50%, PR: 75%, and REL: 75%, respectively). The lowest probability of SVR24 was in NRs with ILF (26%). The SVR24 rate significantly decreased in NRs receiving <60% vs >60% of the total ribavirin dose (23% vs 44%, respectively) or <80% vs >80% of the total ribavirin dose (33% vs 48%, respectively). A significant SVR24 decrease was noted subsequent to a total peginterferon dose reduction, both when comparing patients who received <60% vs >60% of the total dose (NR: 0% vs 44%; REL: 33% vs 68%) and patients who received <80% vs >80% of the total dose (NR: 17% vs 50%; REL: 46% vs 71%). Serious adverse events were observed in 31 patients (15%). Deaths occurred in 4 patients. All of the deceased subjects were cirrhotic members of the ILF (baseline serum albumin level <35 g/L and/or platelet count <100,000/mm3) group. Ribavirin dose reduction did not affect efficacy in REL but did in NR. Peginterferon dose reduction

    It has been suggested that MMPI-2 scoring requires removal of some items when assessing patients after a traumatic brain injury (TBI). Gass (1991. MMPI-2 interpretation and closed head injury: A correction factor. Psychological assessment, 3, 27-31) proposed a correction procedure in line with the hypothesis that MMPI-2 endorsement may be affected by symptoms of TBI. This study assessed the validity of the Gass correction procedure. A sample of patients with a TBI (n = 242), and a random subset of the MMPI-2 normative sample (n = 1,786). The correction procedure implies a failure of measurement invariance across populations. This study examined measurement invariance of one of the MMPI-2 scales (Hs) that includes TBI correction items. A four-factor model of the MMPI-2 Hs items was defined. The factor model was found to meet the criteria for partial measurement invariance. Analysis of the change in sensitivity and specificity values implied by partial measurement invariance failed to indicate significant practical impact of partial invariance. Overall, the results support continued use of all Hs items to assess psychological well-being in patients with TBI. PMID:25413486

    The efficacy and safety of the boceprevir (BOC)-containing triple therapy in Taiwanese treatment-experienced patients remains elusive. After 4 weeks of peginterferon/ribavirin lead-in therapy, patients with cirrhosis or previous null-response received triple therapy for 44 weeks; whereas others received 32 weeks of triple therapy followed by 12 weeks of peginterferon/ribavirin therapy. Patients with HCV RNA > 100 IU/mL at week 12 or with detectable HCV RNA at week 24 of treatment were viewed as futile. A total of 123 patients received treatment. The rates of sustained virological response (SVR) and relapse were 66.7% and 8.9%, respectively by using intention-to-treat analysis. Multivariate analysis revealed that factors associated with SVR included HCV-1b (odds ratio [OR]/ 95% confidence intervals [CI]: 19.23/1.76-525.15, P = 0.01), BOC adherence (7.69/1.55-48.78, P = 0.01), serum albumin (OR/CI:6.25/1.14-40.07, P = 0.03) levels and HCV RNA levels (OR/CI:0.34/0.12-0.79, P = 0.01). Twenty-six (21.1%) patients experienced severe adverse events (SAEs). Multivariate analysis revealed that APRI > 1.5 was the single factor associated with occurring SAEs (OR/CI: 3.77/ 0.97-14.98, P = 0.05). Merging the cut-off values of HCV RNA > 7 log IU/mL at baseline and HCV RNA > 6 log IU/mL at week 4 provided the earliest and best combing viral kinetics in predicting week 12/24 futility with the PPV of 100% and accuracy of 93.5%. HCV-1 treatment experienced Taiwanese patients treated with boceprevir-containing triple therapy in real world had comparable efficacy and safety profiles with those reported in clinical trials. Early viral kinetics before week 4 of treatment highly predicted futility at week 12 or 24 of treatment. PMID:26368130

    Background To assess factors associated with visits to GPs, orthopaedists, and non-physician practitioners of complementary medicine (alternative practitioners) by primary care patients with osteoarthritis (OA). Methods Cross-sectional survey among 1250 consecutively addressed patients from 75 primary care practices in Germany. All patients suffered from OA of the knee or hip according to ACR criteria. They received questionnaires collecting sociodemographic data, data about health service utilisation, prescriptions, comorbidities. They also included established instruments as the Arthritis Impact Measurement Scale (AIMS2-SF) to assess disease-specific quality of life and the Patient Health Questionnaire (PHQ-9) to assess depression. Hierarchical stepwise multiple linear regression models were used to reveal significant factors influencing health service utilization. Results 1021 of 1250 (81.6%) questionnaires were returned. Nonrespondents did not differ from participants. Factors associated with health service use (HSU) varied between providers of care. Not being in a partnership, achieving a high score on the PHQ-9, increased pain severity reflected in the “symptom” scale of the AIMS2-SF, and an increased number of drug prescriptions predicted a high frequency of GP visits. The PHQ-9 score was also a predictor for visits to orthopaedists, as were previous GP contacts, a high score in the "symptom" scale as well as a high score in the "lower limb scale" of the AIMS2-SF. Regarding visits to alternative practitioners, a high score in the AIMS -"social" scale was a positive predictor as older people were less likely to visit them. Conclusion Our results emphasize the need for awareness of psychological factors contributing to the use of health care providers. Addressing the revealed factors associated with HSU appropriately may lead to decreased health care utilization. But further research is needed to assess how this can be done successfully.

    This study aimed to identify factors associated with virological response (VR) to raltegravir (RAL)-containing regimens in 468 treatment-experienced but integrase inhibitor-naive HIV-1 patients receiving a RAL-containing regimen. VR was defined at Month 6 (M6) as HIV-1 RNA viral load (VL) <50 copies/mL. The impacts on VR of baseline integrase mutations, VL, CD4 count, genotypic sensitivity score for nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors and protease inhibitors, and the number of new antiretrovirals used for the first time associated with RAL were investigated. For patients with VL >50 copies/mL at M6, integrase mutations selected were characterised. Median baseline VL was 4.2 log(10)copies/mL (IQR 3.3-4.9 log(10) copies/mL) and CD4 count was 219 cells/mm(3) (IQR 96-368 cells/mm(3)). At M6, 71% of patients were responders. In multivariate analysis, baseline VL and CD4 count and ≥ 2 new antiretrovirals among darunavir, etravirine, maraviroc and enfuvirtide were associated with VR to RAL. Neither HIV-1 subtype nor baseline integrase polymorphisms were associated with VR to RAL. Among 63 failing patients at M6, selection of ≥ 1 change in the integrase gene was observed in 49 (77.8%), and 27/63 (42.9%) were considered as RAL-associated resistance mutations. Factors independently associated with the occurrence of ≥ 1 RAL-associated resistance mutation were VL at failure >3 log(10) and having no new drugs associated with RAL. RAL showed great potency in treatment-experienced patients. The number of new drugs associated with RAL was an important factor associated with VR. HIV-1 subtype and baseline integrase polymorphisms do not influence the RAL VR. PMID:23562640

    Plasma aluminum (Al) is routinely tested in many dialysis patients. Aluminum exposure may lead to acute toxicity and levels in excess of ∼2.2 μmol/L (60 μg/L) should be avoided. Historically, toxicity has been caused by excessive dialyzate Al but modern reverse osmosis (RO) water should be Al free. Nevertheless, many units continue to perform routine Al levels on dialysis patients. This single-center study retrospectively analyzed Al levels in plasma, raw water feed, and RO product between 2010 and 2013 using our database (Nephworks 6) with the aim of determining the utility of these measurements. Two thousand fifty-eight plasma Al tests in 755 patients (61.9% male, mean age 64.7 years) were reviewed showing mean ± SD of 0.41 ± 0.30 μmol/L. One hundred eleven (5.4%) tests from 61 patients had Al levels >0.74 μmol/L and 45 (73.8%) of these patients were or had been prescribed Al hydroxide (Al(OH)(3)) as a phosphate binder. Seven patients had Al concentrations >2.2 μmol/L with no source of Al identified in 1 patient. One hundred sixty-six patients taking Al(OH)(3) (78.7% of all patients on Al(OH)(3)) had levels ≤0.74 μmol/L, the odds ratio of plasma Al > 0.74 μmol/L on Al(OH)3 was 9. The cost of plasma Al assay is $A30.60; thus, costs were $A62,974.80 over the study period. Despite RO feed water Al levels as high as 48 μmol/L, Al output from the RO was almost always undetectable (<0.1 μmol/L) with dialyzate Al levels > 2.2 μmol/L only 3 times since 2010, and never in the last 3 years. Routine unselected testing of plasma Al appears unnecessary and expensive and more selective testing in dialysis patients should be considered. PMID:25306885

    This study describes the meaning and practice of holistic self-care for rehabilitation among Thai Buddhist trauma patients living in areas of political unrest where acts of terrorism occur. Eleven Thai Buddhist trauma patients were selected as specified. The data were collected by in-depth interviews between November 2011 and April 2012, and analyzed using the Van Manen method.Those interviewed described "holistic self-care for rehabilitation" as learning (1) to acquire a new life and (2) to bear the increased demands of care as a chronic disease. Health care responses fell into 3 categories: (1) improving physical self-sufficiency and rehabilitation by increasing muscle strength, pain management, and pressure sores; (2) improving psychological well-being by applying positive thinking, making an effort to live independently, and following a set of religious practices; and (3) finding harmony in life through caution and a willingness to adjust one's lifestyle. Although the participants seemed to adapt well to their new lifestyles, extensive support from health care professionals was necessary. This study promotes better understanding of the holistic health care experiences the survivors of trauma have as a result of an unstable political situation that includes aspects of social unrest and terrorism.

    Background Healthcare utilization, especially length of hospital stay and ICU admission, for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) determine overall outcomes in terms of morbidity, mortality and cost burden. Predicting prolonged hospital stay (PHS) and prolonged intensive care (PIC) for AECOPD is useful for rational allocation of resources in healthcare centres. Aim To characterize the pattern of healthcare utilization by COPD patients hospitalized for acute exacerbation, and to identify clinical and laboratory predictors of ‘prolonged hospital stay’ (PHS) and ‘prolonged intensive care’(PIC) Materials and Methods This study attempted through retrospective data analysis, to identify risk factors and evolve prediction models for increased healthcare utilization namely PHS and PIC for AECOPD. The data were extracted from 255 eligible admissions for AECOPD by 166 patients from Aug 2012 to July 2013. Logistic regression analysis was used for identifying predictors and models were tested with area under receiver operating characteristic curve. Results Independent predictors of prolonged hospital stay (≥ 6 days) were chronic respiratory failure at baseline, low saturation at admission, high HbA1c level and positive isolates in sputum culture. Independent predictors of prolonged intensive care (for ≥ 48 hours) were past history of pulmonary tuberculosis, chronic respiratory failure at baseline, low saturation at admission, high leukocyte count and positive culture isolates in sputum. Prediction models evolved from variables available at admission showed AUC 0.805 (95% CI 0.729 – 0.881) and 0.825 (95% CI 0.75 – 0.90) for PHS and ICU admissions respectively. Conclusion Our prediction models derived from simple and easily available variables show good discriminative properties in predicting PHS and PIC for AECOPD. When prospectively validated, these models are useful for rational allocation of services especially in resource

    Background Information and communication technologies have long been acknowledged to support information sharing along the whole chain of care, from the clinic to the homes of patients and their relatives. Thus they are increasingly being considered for improving the delivery of health care services also in light of clinical and technological achievements that propose new treatments requiring a tighter interaction among patients and physicians. Methods The multiagent paradigm has been utilized within an architecture for delivering telemedicine services to chronic outpatients at their domiciles and enforcing cooperation among patients, caregivers, and different members of the health care staff. The architecture sees each communication device such as a palmtop, smart phone, or personal digital assistant as a separate agent upon which different services are deployed, including telemetry, reminders, notifications, and alarms. Decoupling services from agents account for a highly configurable environment applicable to almost any context that can be customized as needed. Results The architecture has been used for designing and implementing a prototypical software infrastructure, called LifePhone, that runs on several communication devices. A basic set of services has been devised with which we were able to configure two different applications that address long-term and short-term monitoring scenarios for diabetes patients. The long-term scenario encompasses telemetry and reminder services for patients undergoing peritoneal dialysis, which is a treatment for chronic renal failure, a diabetes complication. The short-term scenario incorporates telemetry and remote alarms and is applicable for training patients to use an artificial pancreas. Conclusions Our experiments proved that an infrastructure such as LifePhone can be used successfully for bridging the interaction gap that exists among all the components of a health care delivery process, improving the quality of service

    Abstract There is continuous need to track genetic profiles of HIV strains circulating in different geographic settings to hasten vaccine discovery and inform public health and intervention policies. We partially sequenced the reverse transcriptase region of the HIV-1 pol gene from a total of 54 Kenyan patients aged 18–56 years who continued highly active antiretroviral treatment (HAART) for between 8 and 102 months. Subtyping was done using both the JPHMM tool and phylogenetic method. HIV-1 subtype A1 was the predominant strain in circulation, representing 57.4% and 70.4% of all isolates as determined by JPHMM and phylogenetic methods, respectively. Subtypes D (14.8%, 7.4%), C (5.6%, 9.3%), and A2 (0%, 5.6%) were determined at respective prevalence by both methods. JPHMM identified 22.2% of the isolates as recombinants. This surveillance focused on the RT gene and reaffirms the predominance of subtype A and an increasing proportion of recombinant strains in the Kenyan epidemic. PMID:25748548

    Abacavir/lamivudine (ABC/3TC) is a nucleoside reverse transcriptase inhibitor used for treating human immunodeficiency viral (HIV) infections. Hypersensitivity reactions such as skin eruptions caused by ABC are well-known, but rarely occur in Asians. Raltegravir (RAL) is an integrase strand transfer inhibitor, that is now increasingly, used for treating HIV infections because it has few adverse effects. This retrospective analysis assessed the efficacy and safety of combined ABC/3TC and RAL in both treatment-naïve and -experienced Japanese patients with HIV infections. In all 11 treatment-naïve patients (100%), virological suppression to undetectable level was achieved. Liver transaminases, renal function, and serum lipid profiles showed no exacerbations up to 48 weeks of treatment. In 12 patients who were switched from previous regimens to ABC/3TC and RAL, HIV viral load was undetectable in 11 patients (91.6%), but remained detectable in 1 patient with poor adherence. Major reasons for switching regimens to ABC/3TC and RAL were hyperlipidemia and nausea. After switching, these adverse effects improved, and no new adverse effects were observed. Despite the small number of participants in this study, the results support the combination of ABC/3TC and RAL as a possible treatment choice in Japanese individuals with HIV-infection.

    Sixteen experienced cochlear implant patients with a wide range of speech-perception abilities received the SPEAK processing strategy in the Nucleus Spectra-22 cochlear implant. Speech perception was assessed in quiet and in noise with SPEAK and with the patients' previous strategies (for most, Multipeak) at the study onset, as well as after using SPEAK for 6 months. Comparisons were made within and across the two test sessions to elucidate possible learning effects. Patients were also asked to rate the strategies on seven speech recognition and sound quality scales. After 6 months' experience with SPEAK, patients showed significantly improved mean performance on a range of speech recognition measures in quiet and noise. When mean subjective ratings were compared over time there were no significant differences noted between strategies. However, many individuals rated the SPEAK strategy better for two or more of the seven subjective measures. Ratings for "appreciation of music" and "quality of my own voice" in particular were generally higher for SPEAK. Improvements were realized by patients with a wide range of speech perception abilities, including those with little or no open-set speech recognition. PMID:9771630

    People with complex chronic conditions frequently need to navigate their own way through and around a fragmented and siloed health care system. Care coordination is a defining principle of primary care and is frequently proposed as a solution to this problem. However, care coordination requires more time and effort than primary care physicians alone have the capacity to deliver. Although registered nurses (RNs) are skilled team members who can be included in the delivery of coordinated patient care, any model of care coordination that involves RNs needs to fit within the existing health care delivery system. In this study, which used qualitative techniques based on grounded theory and included face-to-face interviews and open coding and theoretical sampling until data saturation was achieved, and which was one component of a larger action research study, we aimed to gain an understanding of the difference between usual chronic condition care and the work of chronic condition care coordination. The researchers interviewed general practitioners and RNs from various general practice sites who were actively coordinating care. Four unique processes were found to define care coordination implementation, namely: (1) moving beyond usual practice by spanning boundaries; (2) relationship-based care; (3) agreed roles and routines among relevant parties; and (4) committing to chronic condition care coordination. The findings suggested that existing professional and organisational cultures required negotiation before care coordination could be integrated into existing contexts. The challenge, however, seems to be in acknowledging and overcoming professional practice boundaries that define existing care through reflective practice and shared resourcing. PMID:23050573

    Forty-nine protease inhibitor (PI)-experienced but amprenavir (APV)-naïve patients experiencing virological failure were treated with ritonavir (RTV) (100 mg twice a day [b.i.d.]) plus APV (600 mg b.i.d.). Patients responded to therapy with a median viral load decrease of −1.32 log10 by week 12. The addition of low-dose RTV enhanced the minimal APV concentration in plasma (APV Cmin) up to 10-fold compared with that obtained with APV (1,200 mg b.i.d.) without RTV. Baseline PI resistance mutations (L10F/I/V, K20M/R, E35D, R41K, I54V, L63P, V82A/F/T/S, I84V) identified by univariate analysis and included in a genotypic score and APV Cmin at week 8 were predictive of the virological response at week 12. The response to APV plus RTV was significantly reduced in patients with six or more of the resistance mutations among the ones defined above. The genotypic inhibitory quotient, calculated as the ratio of the APV Cmin to the number of human immunodeficiency virus type 1 protease mutations, was a better predictor than the virological or pharmacological variables used alone. This genotypic inhibitory quotient could be used in therapeutic drug monitoring to define the concentrations in plasma needed to control replication of viruses with different levels of PI resistance, as measured by the number of PI resistance mutations.

    This qualitative study examined the role of experienced HIV-infected lay individuals who work in HIV medical care settings as educators. Participants in this study had been in the role an average of 4 years, and referred to their work as "peering," a newly coined verb in the vein of nursing. An overarching theme was that the title "peer educator" captured neither the scope of their work, nor the skill set they contribute to patient care. Peers brought unique contributions to the HIV care team that were vital to encouraging patients to stay engaged in care. Peers felt undervalued and expressed the wish to be "professionalized." Results from this study suggest that peers show promise as behavior change agents who can model healthful behaviors, particularly for newly diagnosed patients or those struggling with engagement in HIV care and adherence to treatment. However, peers need and want more formal training in behavior change science, and peer-led services must become more uniform and readily available to patients across HIV care settings. Research is needed to document the positive impact that peers can have on HIV-related health outcomes and to increased knowledge about the attributes of successful peers. PMID:23883321

    Ivermectin (IVM) is exceptionally safe in humans, and is used for mass treatment of onchocerciasis and lymphatic filariasis. However, cases of encephalopathy, sometimes fatal, have been reported in a small number of individuals who harbored large numbers of Loa loa microfilariae (mf). A loss-of-function mutation in the mdr-1 gene in some dog breeds and in mice leads to accumulation of the drug in the brain, causing coma and death. This hypothesis was tested in four individuals from Cameroon who experienced a post-IVM serious adverse event (SAE) and in nine non-SAE matched controls. No loss-of-function mutation was detected in mdr-1 in any subject. However, haplotypes, associated with altered drug disposition, were present as homozygotes in two of the SAE patients (50%), but absent as homozygotes in the controls (0%). An association of high Loa mf load and a genetic predisposition to altered IVM distribution could be involved in IVM SAEs. PMID:20595473

    Purpose Preclinical and early clinical studies have demonstrated that initial therapy with combined BRAF and MEK inhibition is more effective in BRAFV600-mutant melanoma than single-agent BRAF inhibitors. This study assessed the safety and efficacy of dabrafenib and trametinib in patients who had received prior BRAF inhibitor treatment. Patients and Methods In this open-label phase I/II study, we evaluated the pharmacology, safety, and efficacy of dabrafenib and trametinib. Here, we report patients treated with combination therapy after disease progression with BRAF inhibitor treatment administered before study enrollment (part B; n = 26) or after cross-over at progression with dabrafenib monotherapy (part C; n = 45). Results In parts B and C, confirmed objective response rates (ORR) were 15% (95% CI, 4% to 35%) and 13% (95% CI, 5% to 27%), respectively; an additional 50% and 44% experienced stable disease ≥ 8 weeks, respectively. In part C, median progression-free survival (PFS) was 3.6 months (95% CI, 2 to 4), and median overall survival was 11.8 months (95% CI, 8 to 25) from cross-over. Patients who previously received dabrafenib ≥ 6 months had superior outcomes with the combination compared with those treated < 6 months; median PFS was 3.9 (95% CI, 3 to 7) versus 1.8 months (95% CI, 2 to 4; hazard ratio, 0.49; P = .02), and ORR was 26% (95% CI, 10% to 48%) versus 0% (95% CI, 0% to 15%). Conclusion Dabrafenib plus trametinib has modest clinical efficacy in patients with BRAF inhibitor–resistant melanoma. This regimen may be a therapeutic strategy for patients who previously benefited from BRAF inhibitor monotherapy ≥ 6 months but demonstrates minimal efficacy after rapid progression with BRAF inhibitor therapy.

    Clinical data on antiretroviral effectiveness in women are limited, especially long-term data, because women are usually underrepresented in clinical trials. This sub-analysis of a large European non-comparative, retrospective, observational cohort study evaluated gender differences in long-term outcomes in antiretroviral-experienced adult patients with HIV-1 infection switched to an ATV/r-based regimen between October 2004 and March 2007. Data were extracted from 3 European HIV databases every 6 months (maximum follow-up 5 years). Time to virological failure (VF), defined as two consecutive HIV-1 RNA ≥50 c/mL or one HIV-1 RNA ≥50 c/mL followed by treatment discontinuation (TD), and time to TD were analyzed using the Kaplan-Meier method. Associations of gender with VF and TD were analyzed using multivariate Cox proportional models. Safety and tolerability were evaluated. In total, 1294 patients (336 women, 958 men) were analyzed. No gender differences in time to VF were observed; at 3 years, the probability of not having VF was 0.59 (95%CI: 0.52, 0.65) and 0.63 (95%CI: 0.59, 0.67) for women and men, respectively. In multivariate analyses, women had a higher risk of TD than men (hazard ratio [HR], 1.54; 95%CI: 1.28, 1.85) but no increased risk of VF (HR, 1.06; 95%CI: 0.85, 1.33). Safety and tolerability were comparable between genders. In a clinical setting, long-term efficacy and safety outcomes of ATV/r-based regimens were similar by gender. Women had a higher risk of TD but no increased risk of VF. ATV/r is an effective and well-tolerated therapeutic option for treatment-experienced men and women with HIV-1 infection. PMID:23590675

    Fentanyl buccal tablet (FBT) has shown efficacy and tolerability in patients with cancer-related persistent pain treated with maintenance opioids. We conducted a combined analysis of two similarly designed, randomized, placebo-controlled studies to further evaluate the consistency and clinical relevance of analgesia outcomes. Of the 252 patients enrolled, 150 fulfilled the criteria for efficacy analysis and experienced 1,417 breakthrough pain episodes. A consistently greater effect was noted with FBT vs. placebo on the following measures: improvements from baseline of >or=33% and >or=50% in pain intensity (PI), a >or=2-point reduction in PI, and a score of >or=2 for pain relief. Improvements in these clinically meaningful efficacy measures were seen with FBT at 15 minutes (earliest common evaluation) and remained evident at 60 minutes (final common evaluation). They were also reflected in a more favorable global medication performance assessment for FBT over placebo. FBT was generally well tolerated; most adverse events were typical of potent opioid use in a cancer population. Application-site (buccal) abnormalities were infrequent and led to withdrawal of three patients. There were no serious adverse events or deaths attributable to FBT. This analysis suggests that FBT provides an analgesic effect that is consistent across multiple clinically relevant efficacy measures. PMID:20230447

    In order to identify healthcare resource use patterns associated with chronic obstructive pulmonary disease (COPD), resource utilization (RU) data collection was integrated into a randomized, double-blind placebo-controlled study of Viozan (sibenadet HCl). This study enrolled patients with symptomatic, smoking-related COPD, randomized to receive sibenadet or placebo for a 52-week treatment period. A questionnaire establishing typical pre-trial, COPD-related RU was completed by each patient. Subsequent data were collected by means of an Interactive Voice Response System (IVRS) at 30-day intervals (14 time points) during the study and in the follow-up period. The IVRS system facilitated data collection and minimized inconvenience to the patient. Compliance with the requirement to record details of the healthcare services during the year-long study was high. No overall trend for lower RU was associated with sibenadet therapy, which correlates with the lack of sustained clinical effect seen in studies conducted concurrently. These data do, however, provide valuable information on RU associated with COPD and insights into adjustments associated with changes in disease course. Physicians were seen to be the most common source of care for patients with COPD and more of the patients with severe COPD (stage III) than mild (stage I) were seen to utilize the most expensive resources (e.g. inpatient hospital care). For those patients who experienced an exacerbation during the trial (irrespective of treatment group), resource use was increased during the periods when an exacerbation was reported when compared with the periods before or after an exacerbation. The proportion of cases attending the physician doubled and with a trip to the Emergency Room (ER) increased approximately ninefold during the reporting period in which the exacerbation occurred compared with the previous month. This study has shown that use of an IVRS, even in elderly patients, is an effective means of

    Liver disease has emerged as the most common non-AIDS-related cause of death in HIV patients. However, there is limited data regarding this condition including our setting in Ethiopia. Hence, liver enzyme abnormalities among highly active antiretroviral therapy (HAART) experienced and HAART naïve patients were assessed in this study. A total of 164 HAART experienced and 164 HAART naïve patients were studied. Blood specimen was collected to determine alanine aminotransferase (ALT) and aspartate aminotransferase (AST), CD4 count, and viral hepatitis. The prevalence of liver enzyme abnormality was 20.1% and 22.0% among HAART experienced and HAART naïve patients, respectively. The HAART experienced patients had higher mean ALT than HAART naïve patients (P = 0.002). Viral hepatitis (AOR = 6.02; 95% CI = 1.87–19.39), opportunistic infections (AOR = 2.91; 95% CI = 1.04–8.19), current CD4 count <200 cells/mm3 (AOR = 2.16; 95% CI = 1.06–4.39), and male sex (AOR = 1.83; 95% CI = 1.001–3.33) were associated with elevated ALT and/or AST. In conclusion, liver enzyme abnormalities were high in both HAART experienced and HAART naïve HIV-1 infected patients. Hence, monitoring and management of liver enzyme abnormalities in HIV-1 infected patients are important in our setting. PMID:27493798

    Objective To examine how palliative medicine doctors engage patients in end-of-life (hereon, EoL) talk. To examine whether the practice of “eliciting and responding to cues”, which has been widely advocated in the EoL care literature, promotes EoL talk. Design Conversation analysis of video- and audio-recorded consultations. Participants Unselected terminally ill patients and their companions in consultation with experienced palliative medicine doctors. Setting Outpatient clinic, day therapy clinic, and inpatient unit of a single English hospice. Results Doctors most commonly promoted EoL talk through open elaboration solicitations; these created opportunities for patients to introduce–then later further articulate–EoL considerations in such a way that doctors did not overtly ask about EoL matters. Importantly, the wording of elaboration solicitations avoided assuming that patients had EoL concerns. If a patient responded to open elaboration solicitations without introducing EoL considerations, doctors sometimes pursued EoL talk by switching to a less participatory and more presumptive type of solicitation, which suggested the patient might have EoL concerns. These more overt solicitations were used only later in consultations, which indicates that doctors give precedence to patients volunteering EoL considerations, and offer them opportunities to take the lead in initiating EoL talk. There is evidence that doctors treat elaboration of patients’ talk as a resource for engaging them in EoL conversations. However, there are limitations associated with labelling that talk as “cues” as is common in EoL communication contexts. We examine these limitations and propose “possible EoL considerations” as a descriptively more accurate term. Conclusions Through communicating–via open elaboration solicitations–in ways that create opportunities for patients to volunteer EoL considerations, doctors navigate a core dilemma in promoting EoL talk: giving

    Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66). Maintenance therapy (regular long-acting muscarinic antagonists, long-acting beta-2 agonists, inhaled corticosteroids, or theophylline) also increased the risk of AECOPD with both exacerbation definitions (incidence rate ratios 1.65 and 1.73, respectively). The risk of AECOPD was 59%–78% higher in the hospital sample than in the population sample. Conclusion If externally valid conclusions are to be made regarding incidence and predictors of AECOPD, studies should be based on general population samples or adjustments should be made on account of a likely higher incidence in other samples. Likewise, the effect of different AECOPD definitions should be taken into consideration. PMID:27621614

    Background. The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. Methods. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Results. Mean change in HIV-1 RNA at day 8 was −1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. Conclusions. DTG 50 mg BID–based therapy was effective in this highly treatment-experienced population with INI-resistant virus.

    We measured interferon γ–induced protein 10 (IP-10) levels in 428 patients at baseline, week 1, and week 2 of all-oral treatment for hepatitis C virus (HCV) infection. An increased baseline IP-10 level was associated with a T allele in the IL28B gene, an increased alanine aminotransferase level in treatment-naive but not experienced patients, and an increased body mass index. At week 1, the mean decline in plasma IP-10 levels was the same in treatment-naive and treatment-experienced patients (−49%), whereas during week 2 the mean decline in IP-10 levels in treatment-naive patients (−14%) was significantly larger than in treatment-experienced patients (−2%; P = .0176). IP-10 thus may be a surrogate marker of the rate of intracellular viral replication complex decay. PMID:24907384

    or method of monitoring, and nonexistent for cost-effectiveness. Some studies suggest gender and concomitant use of calcineurin inhibitors will affect pharmacokinetic parameters, but the impact of these findings has not been assessed in relation to monitoring versus no monitoring. CONCLUSIONS The state of knowledge about therapeutic drug monitoring of MPA in solid organ transplants is still in its infancy. Until there is more evidence on the utility of routine MPA monitoring in solid organ transplant recipients, patients, clinicians, and other stakeholders (e.g., public and private insurers) will have to decide on a case by case basis whether the possible but uncertain benefits are worth the extra time and expense of monitoring.

    Researchers and practitioners show increasing sinterest in utilizing patient-generated information on the Web. Although the HCI and CSCW communities have provided many exciting opportunities for exploring new ideas and building broad agenda in health, few venues offer a platform for interdisciplinary and collaborative brainstorming about design challenges and opportunities in this space. The goal of this workshop is to provide participants with opportunities to interact with stakeholders from diverse backgrounds and practices—researchers, practitioners, designers, programmers, and ethnographers—and together generate tangible design outcomes that utilize patient-generated information on the Web. Through small multidisciplinary group work, we will provide participants with new collaboration opportunities, understanding of the state of the art, inspiration for future work, and ideally avenues for continuing to develop research and design ideas generated at the workshop.

    Background Patients with differentiated thyroid cancer (DTC) often respond well to treatment but some become refractory to radioactive iodine (RAI) treatment, and treatment options are limited. Despite the humanistic and economic burden RAI refractory disease imposes on patients, published research concerning treatment patterns and health care resource utilization is sparse. Methods Data were collected from an online retrospective chart review study in the US and five European Union (EU) countries (France, Germany, Italy, Spain, and UK) with physicians recruited from an online panel. Physicians (N=211) provided demographics, disease history, treatment information, and health care resource utilization for one to four of their patients with radioactive iodine refractory differentiated thyroid cancer (RR-DTC). Results The majority of the patients with RR-DTC (N=623) were female (56%), and their mean age was 58.2 years. In this sample, 63.2% had papillary thyroid cancer and 57.0% were in Stage IV when deemed RAI refractory. Patients with RR-DTC experienced regional recurrence in the thyroid bed/central neck area (25.3%) and had distant metastatic disease (53.6%). At the time data were collected, 50.7% were receiving systemic treatment. Of those, 78.5% were on first-line treatment and 62.7% were receiving multikinase inhibitors. Regional differences for prescribed treatments were observed; the US was more likely to have patients receiving multikinase inhibitors (79.2%) compared with UK (41.2%) and Italy (17.1%). Additional details regarding treatment patterns and resource utilization are discussed. Conclusion The current study aimed to obtain a greater understanding of RR-DTC treatment globally. These results can assist in the development and implementation of treatment guidelines and ultimately enhance the care of patients with RR-DTC. PMID:27313476

    Background Chronic Thromboembolic Pulmonary Hypertension (CTEPH) results from incomplete resolution of a pulmonary embolus, leading to pulmonary hypertension and progressive right heart failure and death. We aimed to describe the demographics, treatment patterns, health resource utilization and related costs of patients with CTEPH. Methods In specialized PH centres across six European countries, medical charts of CTEPH patients on PH medication were retrospectively extracted (chart review between 2006 and 2009). Resource utilization was valued using country-specific unit costs. Descriptive statistical analyses were performed. Results Twenty-one hospitals documented 119 consecutive CTEPH patients over an average of 25.4 months. Patients were inoperable (83.9%) or persistent after surgery (16.0%) with mean age 67.5 ± 12.3 years, 61% were female. The average 6-minute walking distance was 298 ± 120 meters, and NYHA class II/III/IV was 27/59/14%. At baseline, 59.7% patients received endothelin receptor antagonist, 34.4% phosphodiesterase-5 inhibitors, and 5.8% prostacyclin. Adding a second PH medication was the most common regimen change. CTEPH patients experienced 1.8 ± 2.2 hospitalizations per year accounting for 14.8 ± 26.1 days in hospital. Patients paid on average 2.8 office visits per year to their general practitioner and 1.3 visits to a specialist. Unadjusted annual mortality rate was 6.0%. Annual cost of PH specific medication was the predominant economic factor averaging € 36,768 per year. Costs for hospitalizations (€ 4,496) and concomitant medications (€ 2,510) were substantially lower. Other health care resource items only accounted for marginal additional costs. Conclusion CTEPH patients are characterised by substantial morbidity and mortality. Health care utilisation, predominantly due to off-label use of PH drugs, is significant. PMID:24912804

    Objectives To identify demographic, medical, and psychosocial characteristics that distinguished sickle cell disease patients who were frequent utilizers of urgent or emergent care resources from low-utilizing patients. Methods Patients at a large urban comprehensive sickle cell disease treatment center were recruited from clinic or during urgent care visits. Participants who were high utilizers, defined as having more than 4 acute or emergency care visits in the prior 12 months, were compared to patients with more typical utilization patterns on lifetime complications of SCD, family background, psychiatric history, occupational function, coping, depressive symptoms, and personality. Results High utilizers were nearly a decade younger on average; despite this they had a similar lifetime history of SCD complications. High utilizing patients' parents appeared to have greater educational achievement overall. High utilizers reported a nearly three-fold greater prevalence of psychiatric illness in family members than low utilizers. On other measures; including coping strategies, social support, and personality; the two groups were comparable. Discussion The study strengthens emerging evidence that disease severity, familial factors related to greater parental education, and psychiatric illness are important factors in high care utilization in patients with sickle cell disease.

    Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction. Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI). Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis. Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients. Key words:Peridontitis, fibromyalgia, mitocondrial dysfunction, oxidative stress.

    Objective To evaluate the conversion of opioid-experienced patients with chronic moderate-to-severe pain to extended-release morphine sulfate with sequestered naltrexone hydrochloride (MSN) using a standardized conversion guide. Methods This open-label, single-arm study was conducted in 157 primary care centers in the United States. A total of 684 opioid-experienced adults with chronic moderate-to-severe pain were converted to oral administration of MSN from transdermal fentanyl and oral formulations of hydrocodone, hydromorphone, methadone, oxycodone, oxymorphone, and other morphine products using a standardized conversion guide. The primary endpoint was the percentage of patients achieving a stable MSN dose within a 6-week titration phase. Secondary endpoints included duration of time to stable dose, number of titration steps, safety and efficacy measures, and investigator assessment of conversion guide utility. Results Of the 684 patients, 51.3% were converted to a stable dose of MSN (95% confidence interval: 47.5%, 55.1%). The mean (standard deviation) number of days to stable dose was 20 (8.94), and number of titration steps to stable dose was 2.4 (1.37). The majority of adverse events were mild/moderate and consistent with opioid therapy. Mean pain scores at stable dose decreased from baseline. Investigators were generally satisfied with the conversion guide and, in 94% of cases, reported they would use it again. Conclusion Conversion to MSN treatment using the standardized MSN conversion guide was an attainable goal in approximately half of the population of opioid-experienced patients with chronic moderate-to-severe pain. Investigators found the guide to be a useful tool to assist conversion of opioid-experienced patients to MSN. PMID:26185466

    Summary Background The chance of a good response in RA is attenuated in previous anti-TNF users who start new anti-TNF therapy compared to biologic naïve patients. In active RA, those with previous anti-TNF exposure compared to anti-TNF naïve may have different baseline disease activity and patient perceptions when starting a new anti-TNF treatment that could explain the observed response differences. Material/Methods The aim of this study was a post hoc analysis of baseline characteristics of patients enrolled in the Optimization of Adalimumab study that was a treat to target vs. routine care study in patients initiating adalimumab. As per the protocol, a maximum of 20% anti-TNF experienced patients were enrolled in the 300 patient trial. Twelve (4.0%) were excluded who previously used other biologics. Baseline characteristics including age, gender, tender and swollen joint counts, disease activity (DAS28), function (HAQ-DI), patient global assessment, patient satisfaction with current treatment, and inflammatory markers (CRP, ESR), were compared between previously anti-TNF experienced [etanercept or infliximab (EXP)], and anti-TNF naïve patients (NAÏVE). Results The mean (SD) age was 54.8 (13.3) years; 81.0% were female, and 237 (79.0%) were anti-TNF naïve while 51 (17.0%) patients were anti-TNF experienced (29 with etanercept, 16 with infliximab, and 6 for both). The mean (SD) baseline in EXP versus NAÏVE groups respectively was: CRP=21.7(32.9) vs. 17.5(20.7); ESR=28.7(22.5) vs. 29.8(20.4); SJC=10.5(6.0) vs. 10.7(5.6); TJC=12.8(7.1) vs. 12.3(7.3); and DAS28=6.0(1.2) vs. 5.8(1.1). None of the between-group differences were statistically significant, however, the HAQ-DI in EXP was 1.7(0.6) compared to 1.5(0.7) for the NAÏVE (P=0.021). Additionally, EXP patients had a higher patient global score [71.3(26.1) vs. 61.9(26.2), P=0.021]. Conclusions Although anti-TNF naïve and experienced patients who initiated adalimumab were similar, with respect to several

    Shared decision-making is a complex endeavor that should take into account the patient's personal preferences regarding treatment options. To truly empower patients to be partners in decision-making, especially in situations in which their preferences are important, physicians must learn to communicate better and to distinguish between what is "medical fact" versus a "value judgement." Knowing what are, when to ask, and how to ask the right questions will help physicians be effective in guiding patients toward the right treatments. PMID:27226516

    Many studies have tested clinical and behavioral approaches for improving glycemic control in people with diabetes. We review research to identify how blood glucose (BG) values have been used in patient-focused clinical research and interventions. We sought to describe the frequency that BG values have been the focus of patient education research and to characterize the different methods to integrate BG into an intervention, the approaches implemented to support patient education and behavior change, and the nature of communication about BG values. Thirty-four eligible studies were identified that included patient education using BG values. Information regarding the study and intervention characteristics include: 1) Characteristics of the study sample, 2) How BG values were obtained, 3) Use of a graphical interface for BG values, 4) Use of a BG log, 5) BG interpretation and regimen adjustments, 6) Recommended actions to patient, 7) Modality of intervention, and 8) Intervention communication schedule. The review demonstrated that new BG technologies provide outstanding opportunities for greater access to BG data, and for patient support and intervention. However, it also indicated a need to improve and expand support for people with diabetes in their daily use of BG values to maintain and improve glycemic control. In order to make the most sustainable impact on behavior, generalizable skills such as problem solving need to be integrated into BG education. PMID:24057927

    Given the increasing popularity of a hospice inpatient/residential facility (HIRF) among hospice patients and their family members, examining who uses HIRFs has been of increasing importance. Using the 2007 National Home and Hospice Care Survey (NHHCS), we found that about 14% of the hospice patients received care in an HIRF in 2007. Characteristics of patients associated with HIRF use largely match the industry norm for a general inpatient level of care and include having no caregiver or having an incapable caregiver; having imminent death; and being directly admitted to a hospice after discharge from a hospital. Given a recent stricter enforcement of reimbursement rules, however, we call for close monitoring of any change in the number of HIRF beds--particularly in rural and low-income urban areas.

    Incident reports have traditionally been the vehicle for identifying, assessing, and responding to quality gaps in hospitals. Yet because of a variety of barriers, residents often fail to participate in this formal process. The authors created a project to engage residents in incident reporting through the use of an online, anonymous narrative format, faculty-facilitated discussion groups, and involvement of patient safety officers in the educational process. During three months, 36 residents submitted a total of 79 stories about patient care that did not "go as intended." The authors reviewed and scored each story for contributing factors and outcomes. The residents met monthly in small groups with trained faculty facilitators to analyze the stories, which were also shared with the patient safety officers. The stories, narratives of both personal involvement and observed events, ranged from near-misses to sentinel events. Key contributing factors included lapses of professionalism, decision errors, communication/information mishaps, transition mix-ups, and workload difficulties. The narrative format proved a feasible tool for collecting significant, previously unrecognized patient safety issues. Internal medicine residents were willing to discuss gaps in care when given the tools and opportunity for anonymous storytelling and blame-free dialogue. PMID:21952066

    2014-10-21

    Endoscopic ultrasound (EUS) has revolutionized the diagnostic and therapeutic approach to patients with gastrointestinal disorders. Its application in patients with liver disease and portal hypertension is increasing. Patients with chronic liver disease are at risk for development of portal hypertension sequale such as ascites, spontaneous bacterial peritonitis and gastroesophageal varices. Bleeding esophageal and gastric varices are among the most common causes of mortality in patients with cirrhosis. Thus, early detection and treatment improve the outcome in this population. EUS can improve the detection and diagnosis of gastroesophageal varices and collateral veins and can provide endoscopic therapy of gastroesophageal varices such as EUS-guided sclerotherapy of esophageal collateral vessels and EUS-guided cynoacrylate (Glue) injection of gastric varices. EUS can also provide knowledge on the efficacy of pharmacotherapy of portal hypertension. Furthermore, EUS can provide assessment and prediction of variceal recurrence after endoscopic therapy and assessment of portal hemodynamics such as E-Flow and Doppler study of the azygous and portal veins. Moreover, EUS-guided fine needle aspiration may provide cytologic diagnosis of focal hepatic tumors and analysis of free abdominal fluid. Using specialized EUS-guided needle biopsy, a sample of liver tissue can be obtained to diagnose and evaluate for chronic liver disease. EUS-guided fine needle injection can be used to study portal vein pressure and hemodynamics, and potentially could be used to assist in exact measurement of portal vein pressure and placement of intrahepatic portosystemic shunt.

    Patient-reported outcomes (PRO) are defined as reports coming directly from patients about how they feel or function in relation to a health condition and its therapy. Although there are numerous compelling reasons why PRO could be an important help in clinical care, they have not evolved into clinical tools integrated into care. The purpose of this review is to assess existing PRO instruments for heart failure with respect to their psychometric properties and potential for use in clinical care. We performed a systematic search of articles published between July 2008 and January 2015 within the MEDLINE, PROMIS, PROQOLID, and Cochrane Library databases. Included instruments had to be developed and tested for heart failure and have had their development processes and psychometric properties described. A total of 31 instruments were identified, 9 of which met all inclusion criteria. After evaluating each remaining instrument in terms of psychometric and clinical criteria and symptom coverage, only 2 instruments-Minnesota Living with Heart Failure and Kansas City Cardiomyopathy questionnaire-met all evaluation criteria. Although clinically useful PRO instruments exist, increasing education to providers on the value and interpretability of PRO instruments, as well as a more streamlined approach to their implementation in the clinical setting is necessary. A clinical trial comparing the routine use of disease-specific PRO with clinical care could further support their incorporation into practice. PMID:26874386

    Accelerated partial breast irradiation (APBI) represents an evolving technique that is a standard of care option in appropriately selected woman following breast conserving surgery. While multiple techniques now exist to deliver APBI, interstitial brachytherapy represents the technique used in several randomized trials (National Institute of Oncology, GEC-ESTRO). More recently, many centers have adopted applicator-based brachytherapy to deliver APBI due to the technical complexities of interstitial brachytherapy. The purpose of this article is to review methods to evaluate and select patients for APBI, as well as to define potential workflow mechanisms that allow for the safe and effective delivery of APBI. Multiple consensus statements have been developed to guide clinicians on determining appropriate candidates for APBI. However, recent studies have demonstrated that these guidelines fail to stratify patients according to the risk of local recurrence, and updated guidelines are expected in the years to come. Critical elements of workflow to ensure safe and effective delivery of APBI include a multidisciplinary approach and evaluation, optimization of target coverage and adherence to normal tissue guideline constraints, and proper quality assurance methods.

To date, no data are available about utilization and perceived effectiveness of CAM in patients with dystonia. A questionnaire survey on utilization and costs of CAM was completed by 180 members of the German Dystonia Society, a patient advocate group. In total, 131 dystonia patients (73%) were current or former users of CAM, 55 patients used CAM in addition to botulinum toxin A injections, and 86 patients had experience with three or more CAM methods. The options used most widely were acupuncture (56%), relaxation techniques (44%), homeopathy (27%), and massages (26%). Among users of specific CAM methods, breathing therapy, Feldenkrais, massages, and relaxation techniques were perceived as most effective. On average, patients spent 1,513 Euro on CAM without reimbursement. There was no correlation between costs and perceived effectiveness of different methods. In line with other studies on chronically ill patients, our results show that dystonia patients frequently utilize CAM methods, often in addition to conventional treatment. There is a growing need to evaluate scientifically the effect of CAM methods on symptom severity and quality of life in dystonia, to prevent utilization of costly and ineffective CAM treatments.

    Hepatocellular carcinoma (HCC) is a deadly form of liver cancer that is increasingly prevalent. We analyzed global gene expression profiling of 361 HCC tumors and 49 adjacent noncancerous liver samples by means of combinatorial network-based analysis. We investigated the correlation between transcriptome and proteome of HCC and reconstructed a functional genome-scale metabolic model (GEM) for HCC. We identified fundamental metabolic processes required for cell proliferation using the network centric view provided by the GEM. Our analysis revealed tight regulation of fatty acid biosynthesis (FAB) and highly significant deregulation of fatty acid oxidation in HCC. We predicted mitochondrial acetate as an emerging substrate for FAB through upregulation of mitochondrial acetyl-CoA synthetase (ACSS1) in HCC. We analyzed heterogeneous expression of ACSS1 and ACSS2 between HCC patients stratified by high and low ACSS1 and ACSS2 expression and revealed that ACSS1 is associated with tumor growth and malignancy under hypoxic conditions in human HCC.

    The highest quality gray-scale ultrasound images are obtained with high-frequency transducers; however, such high frequencies do not penetrate more than a few centimeters into body tissue. Fortunately, in patients with melanoma, the structures of interest are close to the skin surface, making them ideal targets for examination with high-resolution ultrasound. These include primary cutaneous melanomas, uveal melanomas and the regional lymph nodes draining the skin that lie in the axilla, groin, neck and other locations. Although ultrasound study of primary melanomas arising in the skin and eye has provided some insights, a major role for ultrasound has evolved recently, to provide early detection of metastatic melanoma in regional lymph nodes. Ultrasound is clearly superior to clinical palpation of the nodes during follow-up and, when combined with guided fine-needle biopsy, allows the earliest possible surgical intervention for regional nodal metastases. In the future the use of ultrasound contrast agents may improve the sensitivity of ultrasound in the detection of very small metastatic deposits. PMID:18020929

    Purpose To examine imaging utilization in a matched cohort of patients with and without implantable cardioverter defibrillators (ICD) and to project magnetic resonance imaging (MRI) utilization over a 10‐year period. Materials and Methods The Truven Health MarketScan Commercial claims and Medicare Supplemental health insurance claims data were used to identify patients with continuous health plan enrollment in 2009–2012. Patients with ICDs were identified using ICD‐9 and CPT codes, and matched to patients with the same demographic and comorbidity profile, but no record of device implantation. Diagnostic imaging utilization was compared across the matched cohorts, in total, by imaging categories, and in subpopulations of stroke, back pain, and joint pain. MRI use in the nonimplant group over the 4‐year period was extrapolated out to 10 years for ICD‐indicated patients. Results A cohort of 18,770 matched patients were identified; average age 65.5 ± 13.38 and 21.9% female. ICD patients had significantly less MRI imaging (0.23 0.70 SD vs. 0.00 0.08 SD, P < 0.0001) than nonimplant patients. Among patients with records of stroke/transient ischemic attack (TIA) (ICD 5%, nonimplant 4%) and accompanying diagnostic imaging, 44% of nonimplant patients underwent MRI vs. 1% of ICD patients (P < 0.0001). Forecast models estimated that 53% to 64% of ICD‐eligible patients may require an MRI within 10 years. Conclusion MRI utilization is lower in ICD patients compared to nonimplant patients, yet the burden of incident stroke/TIA, back, and joint pain suggests an unmet need for MR‐conditional devices. J.

    Stigma is a major social barrier that can restrict access to and willingness to seek psychiatric care. Psychiatric consumers may use secrecy and withdrawal in an attempt to cope with stigma. The purpose of this study was to determine the effects of music therapy on self- and experienced stigma in acute care psychiatric inpatients using a randomized design with wait-list control. Participants (N=83) were randomly assigned by cluster to one of three single-session group-based conditions: music therapy, education, or wait-list control. Participants in the music therapy and education conditions completed only posttests while participants in the wait-list control condition completed only pretests. The music therapy condition was a group songwriting intervention wherein participants composed lyrics for "the stigma blues." Results indicated significant differences in measures of discrimination (experienced stigma), disclosure (self-stigma), and total stigma between participants in the music therapy condition and participants in the wait-list control condition. From the results of this randomized controlled investigation, music therapy may be an engaging and effective psychosocial technique to treat stigma. Limitations, suggestions for future research, and implications for clinical practice and psychiatric music therapy research are provided. PMID:24070990

    Purpose: To characterize the demographics and survival outcomes of localized prostate cancer patients who developed biochemical failure (BF) according to a prostate-specific antigen (PSA) nadir plus 2 ng/mL. Methods and Materials: We identified 375 prostate cancer patients who had undergone external beam radiotherapy without androgen deprivation therapy but with sufficient PSA data to study PSA kinetics. Of these patients, we identified 82 with BF. The pretreatment PSA velocity was calculated for each patient. Results: For the BF cohort, 26% were low-risk and 74% were intermediate- or high-risk patients. Of the 82 BF patients, 16 (20%) were noted to have both low-risk disease and a pretreatment low PSA velocity of {<=}2 ng/mL/y (termed 'low-risk low-velocity' [LRLV]). The remaining BF patients had either intermediate- or high-risk features or a high PSA velocity >2 ng/mL/y (termed 'higher risk' [HR]). For patients who had BF, the LRLV group had a delayed median time to BF of 55 months compared with 33 months for the HR patients (p = 0.04). With a median clinical follow-up of 112 months, the 5-year overall survival rate was 100% for the LRLV BF patients vs. 84% for the HR patients (p = 0.02). Conclusions: We observed that LRLV BF patients represent a sizeable proportion of all patients with treatment failure. However, when comparing LRLV BF with HR BF patients, the former had significantly better overall survival and a longer interval to BF. This suggests that not all BF events are equivalent and emphasizes the challenges associated with using BF alone as a surrogate for a survival endpoint.

    Abstract Background: Rehospitalizations are prevalent and associated with decreased quality of life. Although hospice has been advocated to reduce rehospitalizations, it is not known how area-level hospice utilization patterns affect rehospitalization risk. Objectives: The study objective was to examine the association between hospice enrollment, local hospice utilization patterns, and 30-day rehospitalization in Medicare patients. Methods: With a retrospective cohort design, 1,997,506 hospitalizations were assessed between 2005 and 2009 from a 5% national sample of Medicare beneficiaries. Local hospice utilization was defined using tertiles representing the percentage of all deaths occurring in hospice within each Hospital Service Area (HSA). Cox proportional hazard models were used to assess the relationship between 30-day rehospitalization, hospice enrollment, and local hospice utilization, adjusting for patient sociodemographics, medical history, and hospital characteristics. Results: Rates of patients dying in hospice were 27% in the lowest hospice utilization tertile, 41% in the middle tertile, and 53% in the highest tertile. Patients enrolled in hospice had lower rates of 30-day rehospitalization than those not enrolled (2.2% versus 18.8%; adjusted hazard ratio [HR], 0.12; 95% confidence interval [CI], 0.118–0.131). Patients residing in areas of low hospice utilization were at greater rehospitalization risk than those residing in areas of high utilization (19.1% versus 17.5%; HR, 1.05; 95% CI, 1.04–1.06), which persisted beyond that accounted for by individual hospice enrollment. Conclusions: Area-level hospice utilization is inversely proportional to rehospitalization rates. This relationship is not fully explained by direct hospice enrollment, and may reflect a spillover effect of the benefits of hospice extending to nonenrollees. PMID:25879990

    Hemodialysis patients in Japan are aging and thus more patients need support for attending hemodialysis facilities. This study aimed to clarify how dialysis patients utilize the services covered by Japan's public long-term care insurance (LTCI) system. This cross-sectional study was based on LTCI data of March 31, 2009, the latest available data provided by Niigata City, located on the northwest coast of Honshu. Among 30,349 LTCI users in Niigata City, there were 234 dialysis patients. To clarify the characteristics of the dialysis patients, we compared the utilization of LTCI services between the dialysis patients (234 users) and randomly selected 765 non-dialysis users. We also calculated the annual transportation service costs per patient for dialysis patients who continued home care (home care group) and those who switched to long-term hospital care at LTCI care levels 4 and 5 (hospital admission group). These care levels indicate difficulty in walking or maintaining a sitting posture without assistance. The dialysis group more frequently utilized home care and equipment services, such as renting or purchasing care-support products and support for home equipment repair, and utilized facility services and short-stay services (respite care) less frequently (both p < 0.001). Cost per patient was higher in the home care group than in the hospital admission group, because the transportation services for dialysis patients at care levels 4 and 5 involve higher costs. These findings indicate that LTCI services usable for dialysis patients were limited. Therefore, instead of merely subsidizing transportation expenses, transportation services must be improved.

    Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.

    Objective We reviewed the current literature regarding antiretroviral (ARV)-sparing therapy strategies to determine whether these novel regimens can be considered appropriate alternatives to standard regimens for the initial treatment of ARV-naive patients or as switch therapy for those patients with virologically suppressed HIV infection. Methods A search for studies related to HIV dual therapy published from January 2000 through April 2014 was performed using Biosis, Derwent Drug File, Embase, International Pharmaceutical Abstracts, Medline, Pascal, SciSearch, and TOXNET databases; seven major trial registries, and the abstracts of major conferences. Using predetermined criteria for inclusion, an expert review committee critically reviewed and qualitatively evaluated all identified trials for efficacy and safety results and potential limitations. Results Sixteen studies of dual therapy regimens were critiqued for the ARV-naive population. Studies of a protease inhibitor/ritonavir in combination with the integrase inhibitor raltegravir or the nucleoside reverse transcriptase inhibitor lamivudine provided the most definitive evidence supporting a role for dual therapy. In particular, lopinavir/ritonavir or darunavir/ritonavir combined with raltegravir and lopinavir/ritonavir combined with lamivudine demonstrated noninferiority to standard of care triple therapy after 48 weeks of treatment. Thirteen trials were critiqued in ARV-experienced, virologically suppressed patients. The virologic efficacy outcomes were mixed. Although overall data regarding toxicity are limited, when compared with standard triple therapy, certain dual therapy regimens may offer advantages in renal function, bone mineral density, and limb fat changes; however, some dual combinations may elevate lipid or bilirubin levels. Conclusions The potential benefits of dual therapy regimens include reduced toxicity, improved tolerability and adherence, and reduced cost. Although the data reviewed here

    Purpose Homeless individuals face unique challenges in health care. Several US initiatives seeking to advance patient-centered primary care for homeless persons are more likely to succeed if they incorporate the priorities of the patients they are to serve. However, there has been no prior research to elicit their priorities in primary care. This study sought to identify aspects of primary care important to persons familiar with homelessness based on personal experience or professional commitment, and to highlight where the priorities of patients and professionals dedicated to their care converge or diverge. Methods This qualitative exercise asked 26 homeless patients and ten provider/experts to rank 16 aspects of primary care using a card sort. Patient-level respondents (n=26) were recruited from homeless service organizations across all regions of the USA and from an established board of homeless service users. Provider/expert-level respondents (n=10) were recruited from veteran and non-veteran-focused homeless health care programs with similar geographic diversity. Results Both groups gave high priority to accessibility, evidence-based care, coordination, and cooperation. Provider/experts endorsed patient control more strongly than patients. Patients ranked information about their care more highly than provider/experts. Conclusion Accessibility and the perception of care based on medical evidence represent priority concerns for homeless patients and provider/experts. Patient control, a concept endorsed by experts, is not strongly endorsed by homeless patients. Understanding how to assure fluid communication, coordination, and team member cooperation could represent more worthy targets for research and quality improvement in this domain. PMID:26929607

    2011-01-01

    Background Patterns of healthcare utilization and costs in patients beginning pharmacotherapy for generalized anxiety disorder (GAD) have not been well characterized. Methods Using a large US health insurance database, we identified all patients with evidence of GAD (ICD-9-CM diagnosis code 300.02) who initiated pharmacotherapy with medications commonly used to treat GAD (eg, selective serotonin reuptake inhibitors [SSRIs], venlafaxine, benzodiazepines) between 1/1/2003 and 12/31/2007. We examined healthcare utilization and costs over the 12-month periods preceding and following date of initial receipt of such therapy ("pretreatment" and "follow-up", respectively). Patients with incomplete data were excluded. Results A total of 10,275 patients met all study inclusion criteria. Forty-eight percent of patients received SSRIs; 34%, benzodiazepines; and 6%, venlafaxine. SSRIs and venlafaxine were about three times more likely to be used on a long-term basis (> 90 days) than benzodiazepines (p < 0.01). In general, levels of healthcare utilization were higher during follow-up than pretreatment. Mean (SD) total healthcare costs increased from $4812 ($10,006) during pretreatment to $7182 ($22,041) during follow-up (p < 0.01); costs of GAD-related pharmacotherapy during follow-up were $420 ($485). Conclusions More than one-half of patients initiating pharmacotherapy for GAD receive either SSRIs or venlafaxine. Levels of healthcare utilization and costs are greater in the year following initiation of therapy than in the immediately preceding one. PMID:22151689

    This study aims to examine the associations between comorbid conditions and healthcare utilization, medical charges, or mortality of patients with rheumatoid arthritis (RA). Nebraska state emergency department (ED) discharge, hospital discharge, and death certificate data from 2007 to 2012 were used to study the comorbid conditions of patients with RA. RA was defined using the standard International Classification of Diseases (ICD-9-CM 714 or ICD-10-CM M05, M06, and M08). There were more comorbid conditions in patients with RA than in patients without RA. Comorbid conditions were majorly related to healthcare utilization and mortality of patients with RA. In addition to injury, fracture, sprains, and strains, symptoms of cardiovascular and digestive systems, respiratory infection, and chronic obstructive pulmonary disease (COPD) were common comorbid conditions for ED visits. In addition to joint replacement and fracture, infections, COPD and cardiovascular comorbidities were common comorbid conditions for hospitalizations. Cardiovascular, cerebrovascular, and respiratory comorbidities, dementia, malignant neoplasm, and diabetes mellitus were common comorbid conditions for deaths of patients with RA. In addition, the numbers of comorbid conditions were significantly associated with the length of hospital stay and hospital charges for patients with RA. The findings in this study indicated that comorbid conditions are associated with healthcare utilization, medical charges, and mortality of patients with RA. PMID:27106546

    Background: Patients with Crohn's disease in whom tumor necrosis factor antagonist therapy fails have limited treatment options, and the benefit of reintroducing the same therapy remains unclear. Here, we report results from PRECiSE 4 (NCT00160706), an open-label extension study of certolizumab pegol in patients who withdrew from the placebo-controlled studies PRECiSE 1 or 2. Methods: Patients eligible for PRECiSE 4 had Crohn's disease exacerbation on placebo or primary or secondary failure to certolizumab pegol in PRECiSE 1 or 2, and received 400 mg certolizumab pegol subcutaneously at weeks 0, 2, and 4 and every 4 weeks thereafter up to 360 weeks. We assessed safety (adverse events) and efficacy (clinical remission) of extended certolizumab pegol therapy. Results: Patients enrolled in PRECiSE 4 (N = 310; mean age, 37 yr; 58% female; 95% white) had a mean Crohn's disease duration of 8.5 years before entering the qualifying studies. At weeks 52, 104, and 156, remission rates were 28.5%, 17.5%, and 12.6% by nonremitter imputation, and 63.8%, 60.0%, and 63.5% by observed cases, with 47.4%, 31.9%, and 23.2% of patients, respectively, remaining on therapy. By study end (7.5 yr), 92.3% of patients discontinued therapy, 49% on account of adverse events. No new safety signals emerged. Incidence rate (new cases)/100 patient-years was 6.11 for serious infections and 1.29 for malignancies. Conclusions: Certolizumab pegol was effective in many patients who previously discontinued certolizumab pegol for lack or loss of response. Thus, discontinuation of therapy may not always be necessary. Safety was consistent with previous findings. PMID:27400222

    Chronic low back pain (LBP) patients with radiculopathy, or sciatica, experience pain, tingling or numbness radiating down their leg due to compression of the lumbar nerve root. The resulting reduction in somatosensory information from the foot sole may contribute to deficits in standing balance control. This work was designed to investigate the relationship between foot skin sensitivity and standing balance control in chronic LBP patients with associated radiculopathy. Patients (n=9) and matched healthy controls (n=9) were recruited to the study, and were tested for balance control in both quiet standing as well as during rapid arm raise perturbation trials on a force plate. Foot skin sensitivity was tested bilaterally for vibratory threshold (3, 40 and 250 Hz) and touch (monofilament) threshold. Results demonstrate that patients had reduced sensitivity to 250 Hz vibration in their affected compared to unaffected foot (at the great toe and heel), as well as compared to controls (at the great toe), but there were no differences with lower frequency vibratory testing or with monofilament testing. While there were no significant between-group differences in balance measures, moderate statistically significant correlations between 250 Hz sensitivity and quiet standing balance parameters were uncovered. Thus, patients demonstrate reduced high-frequency vibratory sensitivity at the foot sole, and correlations with quiet standing balance measures indicate a connection between these foot skin sensitivity deficits and alterations in balance control. Clinically, this identifies high frequency vibration testing as an important measure of skin sensitivity in patients with radiculopathy. PMID:25887249

    Sickle cell disease (SCD) is an inherited blood disorder that is chronic in nature and manifests itself through many facets of the patient's life. Comprehensive specialty centers have the potential to reduce health care costs and improve the quality of care for patients who have chronic medical conditions such as heart failure and SCD. The purpose of this practice inquiry was to analyze de-identified data for acute care episodes involving SCD in order to create a detailed picture of acute care utilization for adult patients in Delaware with SCD from 2007 to 2009. Gaining a better understanding of acute care utilization for adults with SCD may provide evidence to improve access to high-quality health care services for this vulnerable patient population in the state of Delaware.

    Introduction Prolonged glucocorticoid use may increase the risk of adverse safety outcomes, including cardiovascular events. The European League Against Rheumatism and the Canadian Rheumatology Association advise tapering glucocorticoid dose as rapidly as clinically feasible. There is a paucity of published data on RA that adequately describe concomitant treatment patterns. Methods ACTION (AbataCepT In rOutiNe clinical practice) is a non-interventional cohort study of patients from Europe and Canada that investigated the long-term retention of intravenous abatacept in clinical practice. We assessed concomitant glucocorticoids in patients with established RA who had participated in ACTION and received ≥1 biological agent prior to abatacept initiation. Results The analysis included 1009 patients. Glucocorticoids were prescribed at abatacept initiation in 734 (72.7%) patients at a median 7.5 mg/day dose (n=692). Of the patients who remained on abatacept at 24 months, 40.7% were able to decrease their dose of glucocorticoids, including 26.9% who decreased their dose from >5 mg/day to ≤5 mg/day. Conclusion Reduction and/or cessation of glucocorticoid therapy is possible with intravenous abatacept in clinical practice. PMID:26925253

    Using the 2013 HINTS 4 Cycle 2 data representing a general population sample, this study investigates the effects of patients' experiences of uncertainty about prostate cancer during doctor-patient communication, as well as patients' positive assessments of their cancer-related information-seeking experiences, on their fatalistic beliefs regarding cancer and their trust in physicians. Our tests show significant differences in trust in physicians among men who do and do not experience uncertainty about the prostate-specific antigen (PSA) test during doctor-patient communication. The analysis also indicates that individuals with experiences of uncertainty about the PSA test are more likely than those without such experiences of uncertainty to place their trust in doctors. However, no apparent difference or association exists when there are uncertainties relating to treatment choices regarding slow-growing cancer or treatment side effects. Nevertheless, as hypothesized, individuals who positively evaluate their cancer-related information-seeking experiences are less likely to have fatalistic beliefs about cancer. Furthermore, patients' positive assessments are highly predictive of their levels of trust in their physicians. Additionally, tests of interaction effects show that individuals' levels of education moderate the association between uncertainty experiences about the PSA test and both cancer fatalism and trust in physicians. Further implications and limitations of the study are discussed. PMID:27092867

    Periodontal health states are difficult to quantify and no formal scale quantifying patients' utilities for periodontal health states exits. Multi-attribute utility (MAU) techniques were used to develop such a scale. The MAU scale may be used to quantify patients' assessment of their current periodontal health and that of possible treatment outcomes. Such data, combined with probability values in formal decision analysis techniques would result in improved rationality of treatment planning for periodontal disease. 20 patients attending for routine undergraduate care were interviewed. Data from these interviews were sorted into groups of common interest (domains). Intra-domain health statements were complied from the interview content. 21 patients ranked the intra-domain statements on a scale of 0-100. This same group of patients also performed an inter-domain weighting. Mean results showed that patients were 2X as concerned with how they felt and with the prognosis of possible outcomes, than with how they looked and what facts they knew about their oral health. However, the real value of utilities research lies in application of individual results to treatment planning as there is a wide range of opinion regarding outcome health states. PMID:8891929

    Triple therapy combining a protease inhibitor (PI) (telaprevir or boceprevir), pegylated interferon (PEG-IFN), and ribavirin (RBV) has dramatically increased the chance of eradicating hepatitis C virus (HCV). However, the efficacy of this treatment remains suboptimal in cirrhotic treatment-experienced patients. Here, we aimed to better understand the origin of this impaired response by estimating the antiviral effectiveness of each drug. Fifteen HCV genotype 1-infected patients with compensated cirrhosis, who were nonresponders to prior PEG-IFN/RBV therapy, were enrolled in a nonrandomized study. HCV RNA and concentrations of PIs, PEG-IFN, and RBV were frequently assessed in the first 12 weeks of treatment and were analyzed using a pharmacokinetic/viral kinetic model. The two PIs achieved similar levels of molar concentrations (P = 0.5), but there was a significant difference in the 50% effective concentrations (EC50) (P = 0.008), leading to greater effectiveness for telaprevir than for boceprevir in blocking viral production (99.8% versus 99.0%, respectively, P = 0.002). In all patients, the antiviral effectiveness of PEG-IFN was modest (43.4%), and there was no significant contribution of RBV exposure to the total antiviral effectiveness. The second phase of viral decline, which is attributed to the loss rate of infected cells, was slow (0.19 day−1) and was higher in patients who subsequently eradicated HCV (P = 0.03). The two PIs achieved high levels of antiviral effectiveness. However, the suboptimal antiviral effectiveness of PEG-IFN/RBV and the low loss of infected cells suggest that a longer treatment duration might be needed in cirrhotic treatment-experienced patients and that a future IFN-free regimen may be particularly beneficial in these patients.

    Patients with single ventricle (SV) congenital heart disease (CHD) incur high hospital costs during staged surgical palliation. Health care resource utilization for noncardiac admissions in patients with SV has not been reported. This study sought to compare costs and outcomes for common noncardiac hospital admissions between patients with SV and patients without CHD. Hospital discharge data from the University Health System Consortium from January 2011 to December 2013 was queried for patients aged ≤18 years with International Classification of Diseases, Ninth Revision (ICD-9) codes for SV lesions: hypoplastic left heart syndrome (746.7), tricuspid atresia (746.1), or common ventricle (745.3). Primary diagnosis, direct cost, length of stay (LOS), intensive care unit admission rate and mortality data were obtained. The 10 most common noncardiac admission diagnoses were compared between patients with SV and patients without CHD using t test and Fisher's exact test. Total direct cost, LOS, and intensive care unit admission rate were higher for patients with SV for all diagnoses with the exception of LOS for dehydration, which was not different between groups. Hospital mortality was significantly higher for patients with SV admitted for acute kidney injury, esophageal reflux, failure to thrive, respiratory syncytial virus bronchiolitis and pneumonia. In conclusion, our study demonstrates that patients with SV CHD admitted with noncardiac diagnoses have higher health care resource utilization compared to those without CHD. As long-term survival increases, it can be expected that this patient group will use a disproportionate amount of medical dollars. Further characterization of costs will be important so steps can be taken to reduce or prevent hospitalization in these patients. PMID:27018934

    Vaccine rates in patients on hemodialysis are substantially lower than the Healthy People 2020 targets. The purpose of this study is to utilize the perceptions and cues for action constructs of the Health Belief Model (HBM) to assess the attitudes of patients receiving outpatient hemodialysis regarding acceptance of the seasonal influenza, pneumococcal, and hepatitis B virus vaccines. Vaccine acceptance is defined as receiving the vaccine. Study findings suggest age, perceived susceptibility, and perceived severity increase the odds of getting some vaccines. Findings have implications for the development of patient education materials, interdisciplinary team assessments, and plan of care strategies to increase vaccine acceptance. PMID:25244894

    Background: Lung cancer is associated with rapid disease progression, which can significantly progress over a duration of four to eight weeks. This study examines the time interval lung cancer patients from the interior of British Columbia (BC) experience while undergoing diagnostic evaluation, biopsy, staging, and preparation for treatment. Methods: A chart review of lung cancer patients (n=231) referred to the BC Cancer Agency Centre for the Southern Interior between January 1, 2010 and December 31, 2011 was performed. Time zero was defined as the date of the first abnormal chest imaging. Time intervals, expressed as median averages, to specialist consult, biopsy, oncologic referral, initial oncology consultation, and commencement of oncologic treatment were obtained. Results: The median time interval from first abnormal chest imaging to a specialist consultation was 18 days (interquartile range, IQR, 7-36). An additional nine days elapsed prior to biopsy in the form of bronchoscopy, CT-guided biopsy, or sputum cytology (median; IQR, 3-21); if lobectomy was required, 18 days elapsed (median; IQR, 9-28). Eight days were required for pathologic diagnosis and subsequent referral to the cancer centre (median; IQR, 3-16.5). Once referral was received, 10 days elapsed prior to consultation with either a medical or radiation oncologist (median, IQR 5-18). Finally, eight days was required for initiation of radiation and/or chemotherapy (median; IQR, 1-15). The median wait time from detection of lung cancer on imaging to oncologic treatment in the form of radiation and/or chemotherapy was 65.5 days (IQR, 41.5-104.3).  Interpretation: Patients in the BC Southern Interior experience considerable delays in accessing lung cancer care. During this time, the disease has the potential to significantly progress and it is possible that a subset of patients may lose their opportunity for curative intent treatment. PMID:26543688

  2. Identification of aspects of functioning, disability and health relevant to patients experiencing vertigo: a qualitative study using the international classification of functioning, disability and health

    2012-01-01

    Purpose Aims of this study were to identify aspects of functioning and health relevant to patients with vertigo expressed by ICF categories and to explore the potential of the ICF to describe the patient perspective in vertigo. Methods We conducted a series of qualitative semi-structured face-to-face interviews using a descriptive approach. Data was analyzed using the meaning condensation procedure and then linked to categories of the International Classification of Functioning, Disability and Health (ICF). Results From May to July 2010 12 interviews were carried out until saturation was reached. Four hundred and seventy-one single concepts were extracted which were linked to 142 different ICF categories. 40 of those belonged to the component body functions, 62 to the component activity and participation, and 40 to the component environmental factors. Besides the most prominent aspect “dizziness” most participants reported problems within “Emotional functions (b152), problems related to mobility and carrying out the daily routine. Almost all participants reported “Immediate family (e310)” as a relevant modifying environmental factor. Conclusions From the patients’ perspective, vertigo has impact on multifaceted aspects of functioning and disability, mainly body functions and activities and participation. Modifying contextual factors have to be taken into account to cover the complex interaction between the health condition of vertigo on the individuals’ daily life. The results of this study will contribute to developing standards for the measurement of functioning, disability and health relevant for patients suffering from vertigo. PMID:22738067

    OBJECTIVE Ovarian transposition (OT) is offered to reproductive age women with cervical cancer (CC) to preserve fertility prior to pelvic radiation. The aim of this study was to assess subsequent utilization of fertility treatment in these patients. STUDY DESIGN This is a case series of 216 cervical cancer patients seen in a comprehensive cancer center. 16 patients underwent OT for fertility preservation prior to pelvic radiation. Patients were assessed for utilization of fertility treatment, FSH levels as a measure of ovarian reserve, and functional assessment of chronic illness therapy-cervix cancer (FACT-CX) to assess quality of life after OT. RESULTS 94% of patients maintained regular menstrual cycles three years after OT surgery (15/16). When measured (n=5) serum FSH was normal at baseline, and showed a transient elevation at three months following chemoradiation, with a return to normal levels at six months (Means 6.33±2.94, 48.44±18.63, 12.52±8.25, mIU/ML respectively). Only one patient in this series attempted fertility treatment (in vitro fertilization) following OT, and did not become pregnant. FACT-CX indicated that quality of life did not change significantly over the six months’ duration following OT and chemoradiation therapy. CONCLUSIONS OT preserves menstrual cycle regularity without negatively impacting patients’ quality of life. The utility of OT as an effective fertility preservation option is hampered by the low utilization rate of in vitro fertilization and lack of ovarian reserve assessment following OT. PMID:26380495

    Utility values to estimate quality-adjusted life years (QALYs) for use in cost-utility analyses are usually elicited from members of the general population. Public attitudes and understanding of dementia in particular may mean that values elicited from the general population may differ from patients and carers for dementia health states. This study examines how the population impacts utility values elicited for dementia health states using interviewer-administered time tradeoff valuation of health states defined by the dementia-specific preference-based measures DEMQOL-U (patient-report) and DEMQOL-Proxy-U (carer-report). Eight DEMQOL-U states were valued by 78 members of the UK general population and 71 patients with dementia of mild severity. Eight DEMQOL-Proxy-U states were valued by 77 members of the UK general population and 71 carers of patients with dementia of mild severity. Random-effects generalized least squares regression estimated the impact of population, dementia health state, and respondent sociodemographic characteristics on elicited values, finding that values for dementia health states differed by population and that the difference varied across dementia health states. Patients with dementia and carers of patients with dementia gave systematically lower values than members of the general population that were not due to differences in the sociodemographic characteristics of the populations. Our results suggest that the population used to produce dementia health state values could impact the results of cost-utility analyses and potentially affect resource allocation decisions; yet, currently, only general population values are available for usage.

    In this short communication we present a re-analysis of homeopathic patient data in comparison to control patient data from the same Outpatient´s Unit "Homeopathy in malignant diseases" of the Medical University of Vienna. In this analysis we took account of a probable immortal time bias. For patients suffering from advanced stages of cancer and surviving the first 6 or 12 months after diagnosis, respectively, the results show that utilizing homeopathy gives a statistically significant (p<0.001) advantage over control patients regarding survival time. In conclusion, bearing in mind all limitations, the results of this retrospective study suggest that patients with advanced stages of cancer might benefit from additional homeopathic treatment until a survival time of up to 12 months after diagnosis.

    Objective To compare the investigator assessment of patient risk for prescription opioid misuse, abuse, and diversion with patient self-reports of these activities in a population with chronic pain. Methods As a secondary objective of an open-label, multicenter, primary care-based clinical study to evaluate the success of converting opioid-experienced patients with chronic pain to morphine sulfate with sequestered naltrexone hydrochloride, risk for misuse, abuse, and diversion was assessed using two nonvalidated questionnaires: one was completed by the investigator and another by the patient (Self-Reported Misuse, Abuse, and Diversion [SR-MAD]). In addition, the validated Current Opioid Misuse Measure (COMM) test and urine drug test were used. Results Of the 684 patients assessed by the investigators, 537 returned the self-assessment, SR-MAD. Most patients were assigned by the investigator as low risk for misuse (84.2%), abuse (89.3%), and diversion (94.3%). Of the patients who returned SR-MAD, 60% indicated having taken more opioids than prescribed and 10.9% reported chewing or crushing their opioids in the past. Of the patients who completed COMM, 40.6% were deemed as having aberrant behaviors. COMM results correlated with the risk levels from the investigator assessment. One-third of patients (33.8%) had at least one abnormal urine drug test result. Conclusion More research is needed to better understand the gap between the investigator assessment of potential risk for misuse, abuse, and diversion and the actual extent of these behaviors among patients with chronic pain.

    Introduction In health economic evaluations, mapping can be used to estimate utility values from other health outcomes in order to calculate quality adjusted life-years. Currently, no methods exist to map visual analog scale (VAS) scores to utility values. This study aimed to develop and propose a statistical algorithm for mapping five dimensions of health, measured on VASs, to utility scores in patients suffering from cardiovascular disease. Methods Patients undergoing coronary artery bypass grafting at Aalborg University Hospital in Denmark were asked to score their health using the five VAS items (mobility, self-care, ability to perform usual activities, pain, and presence of anxiety or depression) and the EuroQol 5 Dimensions questionnaire. Regression analysis was used to estimate four mapping models from patients’ age, sex, and the self-reported VAS scores. Prediction errors were compared between mapping models and on subsets of the observed utility scores. Agreement between predicted and observed values was assessed using Bland–Altman plots. Results Random effects generalized least squares (GLS) regression yielded the best results when quadratic terms of VAS scores were included. Mapping models fitted using the Tobit model and censored least absolute deviation regression did not appear superior to GLS regression. The mapping models were able to explain approximately 63%–65% of the variation in the observed utility scores. The mean absolute error of predictions increased as the observed utility values decreased. Conclusion We concluded that it was possible to predict utility scores from VAS scores of the five dimensions of health used in the EuroQol questionnaires. However, the use of the mapping model may be inappropriate in more severe conditions. PMID:24453497

    The purpose of this study was twofold: (a) to examine the stressors experienced by injured athletes during three phases of their recovery from sport injury, and (b) to explore the differences in the stressors experienced by team as compared to individual-sport athletes. Participants comprised previously injured high-level rugby union players (n = 5) and golfers (n = 5). Semi-structured interviews were used to explore the stressors participants experienced during three phases of injury (onset, rehabilitation and return to competitive sport). Within- and cross-case analyses showed that athletes experienced sport, medical/physical, social and financial stressors. There were a number of differences in the stressors experienced across the three phases and between team and individual-sport athletes. Findings have important implications for the design and implementation of interventions aimed at managing the potentially stressful sport injury experience and facilitating injured athletes' return to competitive sport.

    patients. From a tolerability point of view, the emtricitabine-tenofovir association was never withdrawn due to untoward events, while only two cases of early abacavir-lamivudine suspension occurred, due to a probable abacavir hypersensitivity reaction. From our preliminary experience, a major role seems to be played by tenofovir-emtricitabine in first-line treatments (preferably among "compact" regimens based on efavirenz), while the proportionally increased abacavir-lamivudine prescription to pretreated patients is mostly attributable to the different genetic barrier of abacavir (which was often associated with boosted protease inhibitors, in this last patient group). The present availability of two more fixed NRTI combinations favored by their single pill, once-daily administration strongly encourages randomized, controlled "head to head" studies in both first-line and experienced patents, in order to better exploit and target their therapeutic potential, and their most effective associations.

    Background Community-based and institutional dementia care has been compared in cross-sectional studies, but longitudinal information on the effect of institutionalization on health care service utilization is sparse. Methods We analyzed claims data from 651 dementia patients via Generalized Estimation Equations to assess health care service utilization profiles and corresponding expenditures from four quarters before to four quarters after institutionalization. Results In all domains, utilization increased in the quarter of institutionalization. Afterwards, the use of drugs, medical aids, and non-physician services (e.g., occupational therapy and physiotherapy) remained elevated, but use of in- and outpatient treatment decreased. Cost of care showed corresponding profiles. Conclusion Institutional dementia care seems to be associated with an increased demand for supportive services but not necessarily for specialized medical care. PMID:25337076

    Multicentric Castleman disease (MCD) is a rare lymphoproliferative disease. Little is known about how patient clinical features and healthcare utilization varies by human immunodeficiency virus (HIV) status and disease subtype. Data of MCD patients identified between 2000 and 2009 were collected from medical records at two United States treatment centres. Clinical, demographic, and biochemical characteristics, drug therapies and medical utilization were descriptively reported by HIV status and cell histology, and statistically compared with the Fisher's Exact and Kruskal-Wallis tests. Patients (n = 59) had a pathologically and clinically confirmed MCD diagnosis: plasmacytic (42%), hyaline vascular (29%) and mixed (15%); 10% had HIV infection. In the first year after diagnosis, MCD patients on average saw a healthcare provider more than six times, were hospitalized at least once and underwent frequent radiological and laboratory testing. Rituximab was the most commonly used drug therapy, followed by corticosteroids and conventional chemotherapy. One- and 2-year survival was excellent in HIV-negative patients (100% and 97%, respectively) but inferior for HIV-positive cases (67% and 67%, respectively). Heterogeneous treatment decisions were observed in this MCD study; HIV status was the only distinguishing clinical criteria associated with pharmacotherapies. Additional research is necessary to guide treatment of this rare lymphoproliferative disorder. PMID:25208471

    In this study, we evaluated the clinical utility of detecting KRAS mutations in circulating cell-free (ccf)DNA of metastatic colorectal cancer patients. We prospectively recruited 94 metastatic colorectal cancer patients. Circulating cell-free DNA was extracted from plasma samples and analyzed for the presence of seven KRAS point mutations. Using the Invader Plus assay with peptide nucleic acid clamping method and digital PCR, KRAS mutations were detected in the ccfDNA in 35 of 39 patients previously determined to have primary tumors containing KRAS mutations using the Luminex method, and in 5 of 55 patients with tumors containing wild-type KRAS. Curative resection was undertaken in 7 of 34 patients with primary and ccfDNA KRAS mutations, resulting in the disappearance of the mutation from the cell-free DNA in five of seven patients. Three of these patients had tumor recurrence and KRAS mutations in their ccfDNA reappeared. Epidermal growth factor receptor blockade was administered to 24 of the KRAS tumor wild-type patients. Of the 24 patients with wild-type KRAS in their primary tumors, three patients had KRAS mutations in their ccfDNA and did not respond to treatment with epidermal growth factor receptor (EGFR) blockade. We also detected a new KRAS mutation in five patients during chemotherapy with EGFR blockade, before disease progression was detectable with imaging. The detection of KRAS mutations in ccfDNA is an attractive approach for predicting both treatment response and acquired resistance to EGFR blockade, and for detecting disease recurrence.

  16. Factors associated with the utilization and costs of health and social services in frail elderly patients

    2012-01-01

    Background Universal access is one of the major aims in public health and social care. Services should be provided on the basis of individual needs. However, municipal autonomy and the fragmentation of services may jeopardize universal access and lead to variation between municipalities in the delivery of services. This paper aims to identify patient-level characteristics and municipality-level service patterns that may have an influence on the use and costs of health and social services of frail elderly patients. Methods Hierarchical analysis was applied to estimate the effects of patient and municipality-level variables on services utilization. Results The variation in the use of health care services was entirely due to patient-related variables, whereas in the social services, 9% of the variation was explained by the municipality-level and 91% by the patient-level characteristics. Health-related quality of life explained a major part of variation in the costs of health care services. Those who had reported improvement in their health status during the preceding year were more frequent users of social care services. Low informal support, poor functional status and poor instrumental activities of daily living, living at a residential home, and living alone were associated with higher social services expenditure. Conclusions The results of this study showed municipality-level variation in the utilization of social services, whereas health care services provided for frail elderly people seem to be highly equitable across municipalities. Another important finding was that the utilization of social and health services were connected. Those who reported improvement in their health status during the preceding year were more frequently also using social services. This result suggests that if municipalities continue to limit the provision of support services only for those who are in the highest need, this saving in the social sector may, in the long run, result in

    Objective To evaluate the impact of lung function, measured as forced expiratory volume in 1 second (FEV1) % predicted, on health care resource utilization and costs among patients with COPD in a real-world US managed-care population. Methods This observational retrospective cohort study utilized administrative claim data augmented with medical record data. The study population consisted of patients with one or more medical claims for pre- and postbronchodilator spirometry during the intake period (July 1, 2012 to June 30, 2013). The index date was the date of the earliest medical claim for pre- and postbronchodilator spirometry. Spirometry results were abstracted from patients’ medical records. Patients were divided into two groups (low FEV1% predicted [,50%] and high FEV1% predicted [≥50%]) based on the 2014 Global Initiative for Chronic Obstructive Lung Disease report. Health care resource utilization and costs were based on the prevalence and number of discrete encounters during the 12-month postindex follow-up period. Costs were adjusted to 2014 US dollars. Results A total of 754 patients were included (n=297 low FEV1% predicted group, n=457 high FEV1% predicted group). COPD exacerbations were more prevalent in the low FEV1% predicted group compared with the high group during the 12-month pre- (52.5% vs 39.6%) and postindex periods (49.8% vs 36.8%). Mean (standard deviation) follow-up all-cause and COPD-related costs were $27,380 ($38,199) and $15,873 ($29,609) for patients in the low FEV1% predicted group, and $22,075 ($28,108) and $10,174 ($18,521) for patients in the high group. In the multivariable analyses, patients in the low FEV1% predicted group were more likely to have COPD exacerbations and tended to have higher COPD-related costs when compared with patients in the high group. Conclusion Real-world data demonstrate that patients with COPD who have low FEV1% predicted levels use more COPD medications, have more COPD exacerbations, and incur higher

    For several decades, US government agencies have partially supported regional networks of Hemophilia Treatment Centers (HTC). HTC multidisciplinary teams provide comprehensive and coordinated diagnosis, treatment, prevention, education, outreach and surveillance services to improve the health of people with genetic bleeding disorders. However, national data are scarce on HTC-patient population trends and services. The aim of the study was to examine national trends over the past 20 years in patient diagnoses, demographics and health services utilization among the Health Resources and Services Administration (HRSA) and Centers for Disease Control and Prevention (CDC)-supported HTC network. Diagnoses, demographics and health services utilization data from 1990 to 2010 were aggregated from all HTCs using the Hemophilia Data Set (HDS). From 1990 to 2010, the HTC population grew 90% from 17 177 to 32 612. HTC patients with von Willebrand's disease increased by 148%, females by 346%, Hispanic patients by 236% and African Americans by 104%. Four thousand and seventy-five deaths were reported. From 2002 to 2010, annual comprehensive evaluations grew 38%, and persons with severe haemophilia on a home intravenous therapy programme rose 37%. In 2010, 46% of patients were less than 18 years vs. 24% for the general US population. The Hemophilia Data Set documents the growth and diversity of the US Hemophilia Treatment Center Network's patient population and services. Despite disproportionate deaths due to HIV, the HTC patient base grew faster than the general US population. The HDS is a vital national public health registry for this rare-disorder population.

    OBJECTIVES: To determine population size, demographic characteristics, hospital utilization patterns, the specialties of physicians providing care, and costs for hospitalized adult sickle cell patients in Illinois. METHODS: A statewide, administrative dataset for the two-year period from january 1992 through December 1993 was analyzed retrospectively. RESULTS: There were 8403 admissions among 1189 individual sickle cell patients for the two-year period. Eighty-five percent of patients resided in the Chicago metropolitan area. The median age of the 1189 patients was 29; two-thirds had Medicaid or Medicare coverage. Emergency departments were the primary source of admissions (85.7%). The most common admitting diagnosis was painful crisis (97.4%), and average length of stay was four days. The median number of admissions per patient was three; most patients (85%) used only one or two hospitals. A small group used more than four hospitals and accounted for 23% of statewide admissions. Primary care physicians cared for most patients, and total hospitalization charges were more than $59 million. CONCLUSIONS: In Illinois the adult sickle cell population is concentrated in major urban centers, primarily the Chicago metropolitan area. These patients accounted for approximately 8400 admissions and more than $59 million in hospital charges during the two-year study period. A small group of patients used multiple hospitals and accounted for more than 23% of total hospitalization charges. This study shows the necessity of and provides a useful framework for developing targeted programs for adult sickle cell patients as well as for training physicians to efficiently provide comprehensive health care services for this population.

    This study examines the utilization of hospital care by HIV patients in all hospitals in eight states (California, Colorado, Florida, Kansas, New Jersey, New York, Pennsylvania, and South Carolina), and examines the cost of hospital care for HIV patients in six of these states (California, Colorado, Kansas, New Jersey, New York, and South Carolina). The eight states in the sample account for more than 52% of all persons living with AIDS in the United States; the six states account for 39%. The unit of observation in both studies is a hospital admission by a patient with HIV. Hospital data were obtained from the Healthcare Cost and Utilization Project (HCUP), State Inpatient Database (SID), which is maintained by the Agency for Healthcare Research and Quality (AHRQ). The HCUP contains hospital discharge data and is a federal/state/industry partnership to build a multistate health care data system. Using multivariate analytic techniques and data from 2000, results indicate that cost and length of a hospital stay vary significantly across states after accounting for a patient's gender, insurance type, race, age, and number of diagnoses, as well as the teaching status and ownership category of the hospital.

    2013-01-01

    Background A variety of instruments are used to measure health related quality of life. Few data exist on the performance and agreement of different instruments in a depressed population. The aim of this study was to investigate agreement between, and suitability of, the EQ-5D-3L, EQ-5D Visual Analogue Scale (EQ-5D VAS), SF-6D and SF-12 new algorithm for measuring health utility in depressed patients. Methods The intraclass correlation coefficient (ICC) and Bland and Altman approaches were used to assess agreement. Instrument sensitivity was analysed by: (1) plotting utility scores for the instruments against one another; (2) correlating utility scores and depressive symptoms (Beck Depression Inventory (BDI)); and (3) using Tukey’s procedure. Receiver Operating Characteristic (ROC) analysis assessed instrument responsiveness to change. Acceptability was assessed by comparing instrument completion rates. Results The overall ICC was 0.57. Bland and Altman plots showed wide limits of agreement for each pair wise comparison, except between the SF-6D and SF-12 new algorithm. Plots of utility scores displayed ’ceiling effects’ in the EQ-5D-3L index and ’floor effects’ in the SF-6D and SF-12 new algorithm. All instruments showed a negative monotonic relationship with BDI, but the EQ-5D-3L index and EQ-5D VAS could not differentiate between depression severity sub-groups. The SF-based instruments were better able to detect changes in health state over time. There was no difference in completion rates of the four instruments. Conclusions There was a lack of agreement between utility scores generated by the different instruments. According to the criteria of sensitivity, responsiveness and acceptability that we applied, the SF-6D and SF-12 may be more suitable for the measurement of health related utility in a depressed population than the EQ-5D-3L, which is the instrument currently recommended by NICE.

    The aim of the study was to compare the responsiveness of disease-specific (Arthritis Impact Measurement Scale 2, AIMS2), generic (Medical Outcome Study Short Form Health Survey, SF-36) and preference-based instruments (rating scale, RS and time tradeoff, TTO) to changes in articular status and perceived health in patients with rheumatoid arthritis (RA). Seventy-eight consecutive patients with RA, attending the care facilities of the Department of Rheumatology of Ancona, were recruited in this longitudinal study. In order to assess the responsiveness three strategies were used: effect size (ES), standardised response mean (SRM) and receiver operating characteristic (ROC). There were 55 women and 23 men with a mean age of 56 years (range 19-78) and arthritis duration of 7.1 years (range 6 months to 24 years). Using three-category EULAR criteria as external indicators of improvement/response, 21 patients (27%) reported a significant improvement, 23 (29.5%) moderate improvement, and 34 (43.5%) no change over the 12-month period. The mean change scores in generic and specific health status instruments and utility measures were significantly related to response category. The AIMS2 subscales (physical function, pain, psychological function and social interaction) were slightly more responsive than those of SF-36. The physical and pain dimensions were most sensitive for measuring change over a 12-month period, followed by psychological and social dimensions. For the utility measurement, RS scores were found to be significantly more responsive in detecting changes in preferences than TTO scores. These results may have implications for the application of the health status and utility measures in clinical trials in patients with RA. PMID:12447631

    2015-01-01

    Induction of labor is one of the most commonly performed obstetric procedures and will likely become more common as the reproductive population in developed nations changes. As the proportion of women undergoing induction grows, there is a constant search for more efficacious ways to induce labor while maintaining fetal and maternal safety as well as patient satisfaction. With almost half of induced labors requiring cervical ripening, methods for achieving active labor and vaginal delivery are constantly being investigated. Prostaglandins have been shown to be effective induction agents, and specifically vaginal misoprostol, used off-label, have been widely utilized to initiate cervical ripening and active labor. The challenge is to administer this medication accurately while maintaining the ability to discontinue the medication when needed. The misoprostol vaginal insert initiates cervical ripening utilizing a delivery system that controls medication release and can be rapidly removed. This paper reviews the design, development, and clinical utility of the misoprostol vaginal insert for induction of labor as well as patient considerations related to the delivery system.

    Facioscapulohumeral dystrophy (FSHD) is a rare inherited neuromuscular disease estimated to affect 1/15,000 people. Through basic research, remarkable progress has been made towards the development of targeted therapies. Patient identification, through registries or other means is essential for trial-readiness. The UK FSHD Patient Registry is a patient initiated registry that collects standardised and internationally agreed dataset of self-reported clinical details combined with professionally verified genetic information. It includes four additional questionnaires to capture patient reported outcomes related to pain, quality of life and scapular fixation. Between 2013 and 2015, 518 patients registered 243 males, 241 females with a mean age of 47.8 years. Most of the patients have FSHD type 1 (91.7 %), and weakness of the facial (59.2 %) was the most prevalent symptom at onset, followed by shoulder-girdle muscles (53.3 %) and distal (22.45 %) or proximal lower limb weakness (14.8 %). 85.57 % patients were ambulant or ambulant with assistance at the time of registration, 7.9 % report respiratory insufficiency. The registry has demonstrated utility with the recruitment of patients for a natural history study of infantile onset FSHD, and the longitudinal analysis of patient-related outcomes will provide much-needed baseline information to power future trials. The internationally agreed core dataset enables national registries to participate in a "Global FSHD registry". We suggest that the registry's ability to interoperate with other large datasets will be instrumental for sharing and exploiting data globally. PMID:27159994

    Kabuki syndrome (KS) is a dominantly inherited disorder mainly due to de novo pathogenic variation in KMT2D or KDM6A genes. Initially, a representative cohort of 14 Czech cases with clinical features suggestive of KS was analyzed by experienced clinical geneticists in collaboration with other specialties, and observed disease features were evaluated according to the 'MLL2-Kabuki score' defined by Makrythanasis et al. Subsequently, the aforementioned genes were Sanger sequenced and copy number variation analysis was performed by MLPA, followed by genome-wide array CGH testing. Pathogenic variants in KMT2D resulting in protein truncation in 43% (6/14; of which 3 are novel) of all cases were detected, while analysis of KDM6A was negative. MLPA analysis was negative in all instances. One female patient bears a 6.6 Mb duplication of the Xp21.2-Xp21.3 region that is probably disease causing. Subjective KS phenotyping identified predictive clinical features associated with the presence of a pathogenic variant in KMT2D. We provide additional evidence that this scoring approach fosters prioritization of patients prior to KMT2D sequencing. We conclude that KMT2D sequencing followed by array CGH is a diagnostic strategy with the highest diagnostic yield. PMID:26841933

    OBJECTIVE. This study describes demographic characteristics of pediatric AIDS patients, describes hospital and community-based service utilization patterns, and analyzes medical and social support service usage patterns with respect to patient demographic characteristics, clinical trial participation, functional/developmental status, and social environment. DATA SOURCES AND STUDY SETTING. Data reported in this study are from the AIDS Costs and Service Utilization Survey (ACSUS) and cover the six-month period beginning March 1991 (N = 135). Pediatric patients who sought care for HIV-related problems were sampled at seven different hospitals in five metropolitan regions of the United States. All of the participating hospitals had clinics specifically serving pediatric patients infected with HIV. The sample consists of HIV-positive patients who had had at least one HIV-related symptom or condition. STUDY DESIGN. A stratified probability sample design guided the sampling strategy, which included oversampling in two large hospitals from two of the five metropolitan areas. Survey data cover an 18-month time period of health care utilization, cost, and financing information from HIV-infected patients and their providers. Utilization measures are standardized to a six-month period. Per capita income, family structure, informal personal network, functional status, and clinical trial participation are tested for associations with patterns of utilization. In addition, a weighted ten-point social severity scale was developed to assess family/household stability. DATA COLLECTION. Data were collected through a screener instrument completed by the person accompanying the child to a hospital clinic visit (usually a a parent), and through two interviews conducted in person with the patients' primary caregivers. Data from the questionnaires were coded and assembled into computerized SAS analysis files by WESTAT. PRINCIPAL FINDINGS. Children in this sample are 62 percent African

    .26-1.53, p < 0.0001). CONCLUSIONS A significant majority of patients discharged from hospitals in the US from 1998 to 2007 with a primary diagnosis of LBP were admitted through the ER, with more patients being admitted via this route each year. These patients were less likely to be discharged directly home compared with patients with LBP who were not admitted through the ER. Uninsured and African American patients with LBP were more likely to be admitted through the ER than their counterparts, as were patients with more preexisting health problems. Interestingly, patients with LBP at the highest income levels were more likely to be admitted through hospital ERs. The findings suggest that socioeconomic factors may play a role in the utilization of ER resources by patients with LBP, which in turn appears to impact at least the short-term outcome of these patients.

    2015-01-01

    Cardiac biomarkers, such as cardiac troponin T (cTnT), brain natriuretic peptide (BNP), and N-terminal-pro-BNP (NT-pro-BNP), are commonly used to diagnose acute coronary syndrome and congestive heart failure exacerbation in symptomatic patients. Levels of these biomarkers are frequently chronically elevated in asymptomatic patients with ESRD who are receiving maintenance dialysis. Other imaging biomarkers commonly encountered in nephrologists’ clinical practice, such as coronary artery calcium measured by computed tomography, left ventricular hypertrophy, and carotid intima-media thickness, are also frequently abnormal in asymptomatic patients with ESRD. This article critically reviews the limited observational data on associations between cTnT, BNP, NT-pro-BNP, coronary artery calcium, left ventricular hypertrophy, and carotid intima-media thickness with cardiovascular events and death in non–dialysis-dependent patients with CKD. Although sufficient evidence suggests that these biomarkers may be used for prognostication, the diagnostic utility of cTnT, BNP, and NT-pro-BNP remain challenging in patients with CKD. Decreased renal clearance may affect the plasma levels of these biomarkers, and upper reference limits were originally derived in patients without CKD. Until better data are available, higher cutoffs, or a rise in level compared with previous values, have been proposed to help distinguish acute myocardial infarction from chronic elevations of cTnT in symptomatic patients with CKD. Additionally, it is not known whether these biomarkers are modifiable and amenable to interventions that could change hard clinical outcomes in patients with CKD not yet undergoing long-term dialysis.

    Patients with upper gastrointestinal (GI) bleeding frequently require hospitalization and have a mortality rate that ranges from 6% to 14%. These patients need rapid clinical assessment to determine the urgency of endoscopy and the need for endoscopic treatment. Risk-scoring tools, such as the Rockall score and the Glasgow-Blatchford score, are commonly used in this assessment. These tools clearly help identify high-risk patients but do not necessarily have good predictive value in identifying important outcomes. Their diagnostic accuracy in identifying rebleeding and mortality ranges from poor to fair. The shock index (heart rate divided by systolic blood pressure) provides an integrated assessment of the cardiovascular status. It can be easily calculated during the initial evaluation of patients and monitoring after treatment. The shock index has been used in a few studies in patients with acute GI bleeding, including studies to determine which patients need emergency endoscopy, to predict complications after corrosive ingestions, to identify delayed hemorrhage following pancreatic surgery, and to evaluate the utility of angiograms to identify sites of GI bleeding. Not all studies have found the shock index to be useful in patients with GI bleeding, however. This may reflect the unpredictable natural history of various etiologies of GI bleeding, comorbidity that may influence blood pressure and/or heart rate, and inadequate data acquisition. The shock index needs more formal study in patients with GI bleeding admitted to medical intensive care units. Important considerations include the initial response to resuscitation, persistent bleeding following initial treatment, and rebleeding following a period of stabilization. In addition, it needs correlation with other risk-scoring tools. PMID:26954657

    Serum iron and ferritin measurements lack the requisite sensitivity and/or specificity to accurately diagnose iron deficiency. To determine their utility in hospitalized patients, the authors compared the results of these tests with the presence of stainable iron in bone marrow aspirates of 301 patients. Forty (13.3%) had absent marrow iron. The serum diagnosis of iron deficiency was accepted on the basis of the following: iron less than 11 mumol/L, total iron-binding capacity (TIBC) greater than 45 mumol/L, transferrin saturation (%Sat) less than 0.20, and ferritin less than 13 micrograms/L for females and less than 25 micrograms/L for males. Using these criteria, iron deficiency was correctly diagnosed by serum iron in 41%, TIBC in 84%, %Sat in 50%, and ferritin in 90% of the patients. The serum ferritin is clearly the only useful serum test for diagnosing iron deficiency in hospitalized patients but is limited by a low sensitivity. The bone marrow examination is the most sensitive test for diagnosing iron deficiency in hospitalized patients. PMID:2242107

    Background Human genetic factors influence the outcome of pegylated interferon and ribavirin hepatitis C therapy. We explored the role of IL28B, APOH and ITPA SNPs on the outcomes of triple therapy including telaprevir or boceprevir in patients with compensated cirrhosis chronically infected with HCV-1. Patients and Methods A total of 256 HCV-1 Caucasian treatment-experienced patients with compensated cirrhosis from the ANRS CO20-CUPIC cohort were genotyped for a total of 10 candidate SNPs in IL28B (rs12979860 and rs368234815), APOH (rs8178822, rs12944940, rs10048158, rs52797880, rs1801689 and rs1801690) and ITPA (rs1127354 and rs7270101). We tested the association of IL28B and APOH SNPs with sustained virological response and of ITPA SNPs with anemia related phenotypes by means of logistic regression assuming an additive genetic model. Results None of the six APOH SNPs were associated with sustained virological response. The favorable alleles of the IL28B SNPs rs12979860 and rs368234815 were associated with sustained virological response (rs12979860: OR = 2.35[1.50–3.70], P = 2x10-4). Refined analysis showed that the effect of IL28B SNPs on sustained virological response was restricted to prior PegIFN/RBV relapse (OR = 3.80[1.82–8.92], P = 8x10-4). We also confirmed the association between ITPA low activity alleles and protection against early hemoglobin decline in triple therapy (P = 2x10-5). Conclusion Our results suggest that the screening of rs12979860 may remain interesting for decision making in prior relapse HCV-1 Caucasian patients with compensated cirrhosis eligible for a telaprevir- or boceprevir-based therapy.

    Determining D-dimer levels remains important in the diagnostic algorithms for venous thromboembolism (VTE). The present study aimed to identify factors influencing D-dimer utility in diagnosing VTE. Consecutive symptomatic medical patients, who attended our emergency department from 1 November 2006 to 31 December 2006, had D-dimer levels measured as fibrinogen equivalent units (FEU), following clinical risk assessment. Diagnosis of VTE was established by venous compression ultrasonography and computed tomographic pulmonary angiography. VTE-negative patients were followed for 2 months to detect future occurrence of thromboembolism. Impact of various factors on D-dimer levels was analyzed. Four thousand and twenty-six patients attended our emergency department, and 525 patients (median age 52 years) had D-dimer assessed. Final diagnosis of VTE was established in 25 (4.7%) patients on radiological investigations. Median D-dimer levels for VTE-negative patients less than 60 years old, with normal renal function and chest radiology were 0.38 microgFEU/ml (range 0.19-2.3), 0.39 microgFEU/ml (range 0.17-3.5) and 0.39 microgFEU/ml (range 0.1-4.3), respectively. Similar figures for those at least 60 years, with renal impairment and abnormal chest radiology, were 0.75 microgFEU/ml (range 0.22-4.3), 0.52 microgFEU/ml (range 0.17-4.4) and 0.92 microgFEU/ml (range 0.26-5.6), respectively. Factors including patient age, renal function and chest radiology had significant influence on D-dimer levels (P < 0.01). A triad of patient age at least 60 years, renal impairment (modification of diet in renal disease stage 2-5) and abnormal chest radiology had a false positive D-dimer in 96% of patients (n = 72). Use of D-dimer in patients with a triad of advanced age, renal impairment and abnormal chest radiology has no practical diagnostic value in VTE. PMID:19276796

  13. Text message program improves outcomes, decreases ED utilization among ED patients with poorly controlled diabetes.

    2014-02-01

    Diabetic patients who lack access to primary care tend to frequent the ED, often with complications from their disease that could have been prevented with proper management and education. To get around the problem of access, researchers tested an automated program that continuously delivered educational messaging via text to a group of patients who presented to the ED with poorly controlled diabetes. After six months, researchers noted improvements in Hb A1c levels, self-reported medication adherence, and ED utilization when compared with a control group. And the impact was particularly noteworthy among Latinos, according to the researchers. The text messaging program, dubbed TExT-Med, was developed by four physicians and two diabetes educators. The messages were delivered daily, and contained educational as well motivational content derived from the National Diabetes Education Program.There were also medication reminders, healthy living challenges, and trivia questions about diabetes. At six months, Hb A1c levels decreased by 1.05% in the intervention group, compared to 0.60% in the control group, and self-reported medication adherence improved from 4.5 to 5.4 (as measured on an 8 point scale) in the intervention group versus a decrease of 0.1 in the control group. During the six-month study period, 35.9% of patients in the intervention group presented to the ED for care, as compared to 51.6% of patients in the control group. PMID:24505864

    Vertigo and dizziness count among the most frequent symptoms in outpatient practices. Although most vestibular disorders are manageable, they are often under- and misdiagnosed in primary care. This may result in prolonged absence from work, increased resource use and, potentially, in chronification. Reliable information on health services utilization of patients with vertigo in primary care is scarce. Retrospective cohort study in patients referred to a tertiary care balance clinic. Included patients had a confirmed diagnosis of benign paroxysmal positional vertigo (BPPV), Menière's disease (MD), vestibular paroxysmia (VP), bilateral vestibulopathy (BVP), vestibular migraine (VM), or psychogenic vertigo (PSY). All previous diagnostic and therapeutic measures prior to the first visit to the clinic were recorded. 2,374 patients were included (19.7 % BPPV, 12.7 % MD, 5.8 % VP, 7.2 % BVP, 14.1 % VM, 40.6 % PSY), 61.3 % with more than two consultations. Most frequent diagnostic measures were magnetic resonance imaging (MRI, 76.2 %, 71 % in BPPV) and electrocardiography (53.5 %). Most frequent therapies were medication (61.0 %) and physical therapy (41.3 %). 37.3 % had received homoeopathic medication (39 % in BPPV), and 25.9 % were treated with betahistine (20 % in BPPV). Patients had undergone on average 3.2 (median 3.0, maximum 6) diagnostic measures, had received 1.8 (median 2.0, maximum 8) therapies and 1.8 (median 1.0, maximum 17) different drugs. Diagnostic subgroups differed significantly regarding number of diagnostic measures, therapies and drugs. The results emphasize the need for establishing systematic training to improve oto-neurological skills in primary care services not specialized on the treatment of dizzy patients. PMID:24817192

    Background Despite ACC/AHA guidelines indicating implantable cardioverter defibrillator (ICD) as class I therapy for primary prevention of sudden cardiac death in patients with EF≤35%, ICD utilization rates in real world practice have been low. Objective To determine the rate of ICD implantation at a tertiary care academic center and to assess the reasons for under-utilization of the same. Methods Review of a prospectively collected database which included all patients diagnosed with an EF≤35% was performed to assess the rate of ICD implantation and mortality. Reasons for non-implantation of ICD were then assessed from detailed chart review. Results A total of 707 patients (age 69.4 ± 14.1 years) with mean EF of 26±7% were analyzed. Only 28% (200/707) of patients had ICDs implanted. Mortality was lower in the group with ICD (25% vs 37%, p=0.004). When patients who either died or were lost to follow-up prior to 2005 were excluded, ICD utilization rate was still low at 37.6%. The most common reason for non-implantation of ICD was physicians not discussing this option with their patients. Patient refusal was the second most common reason. Conclusions ICD Implantation rates for primary prevention of SCD in patients with EF≤35% is low. Physician and patient education should be addressed to improve the utilization rates. PMID:25852239

    Biomarkers of inflammation, especially C-reactive protein (CRP), have been consistently shown to predict poor outcomes in chronic hemodialysis (CHD) patients. However, the determinants of CRP and the value of its monitoring in CHD patients have not been well defined. We conducted a retrospective cohort study to evaluate possible determinants of the inflammatory response in CHD patients with a focus on dialysis catheter utilization. Monthly CRP were measured in 128 prevalent CHD patients (mean age 56.6 years [range 19-90], 68% African Americans, 39% diabetics [DM]) over a mean follow-up of 12 months (range 2-26 months). There were a total of 2405 CRP measurements (median 5.7 mg/L; interquartile range [IQR] 2.4-16.6 mg/L). The presence of a dialysis catheter (p<0.002), cardiovascular disease (p=0.01), male gender (p=0.005), higher white blood cell count (p<0.0001), elevated phosphorus (p=0.03), and lower cholesterol (p=0.02) and albumin (p<0.0001) concentrations were independent predictors of elevated CRP in the multivariate analysis. Additionally, CRP levels were significantly associated with the presence of a catheter, when comparing the levels before and after catheter insertion (p=0.002) as well as before and after catheter removal (p=0.009). Our results indicate that the presence of a hemodialysis catheter is an independent determinant of an exaggerated inflammatory response in CHD patients representing a potentially modifiable risk factor.

    PubMed Central

    2011-01-01

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available.

    Temporomandibular joint (TMJ) ankylosis is a pathological condition characterized by articular bony or fibrous tissue fusion. TMJ ankylosis developing during childhood can lead to growth complications because of the loss of mandibular function. Hard and soft autogenous tissue grafting has been used for TMJ reconstruction in the growing patient. However, in cases where autogenous tissue grafts fail either due to unpredictable growth or ankylosis, total alloplastic temporomandibular joint replacement (TMJ TJR) can provide a viable option. The case of a 7-year old female suffering from recurrent bilateral TMJ ankylosis resulting from birth trauma, and with concomitant obstructive sleep apnea syndrome (OSAS) is presented. Due to prior surgical and autogenous graft failures, the decision was made to complete her joint reconstructions utilizing patient-fitted TMJ prostheses. Questions have been raised about the longevity of TMJ TJR devices as well as their lack of growth potential, but children with TMJ ankylosis do not have condyle-related growth potential and that replacing failed autogenous tissue graft material with more autogenous tissue will result in the same adverse outcomes. Therefore, in growing patients with recurrent TMJ ankylosis and/or failed autogenous tissue grafts, there may be a role for TMJ TJR. PMID:26920044

    Objective: to know the ethical problems experienced by oncology nurses. Method: descriptive and exploratory study with a qualitative approach, performed in inpatient units and in chemotherapy out-patients units that provide assistance to oncological patients in two capitals in the South region of Brazil. Eighteen nurses participated in this study, selected by snowball sampling type. For data collection, semi-structured interviews were carried out, which were recorded and transcribed, and then analyzed by thematic analysis. Results: two categories were established: when informing or not becomes a dilemma - showing the main difficulties related to oncological treatment information regarding health staff, health system, and infrastructure; to invest or not - dilemmas related to finitude - showing situations of dilemmas related to pain and confrontation with finitude. Conclusion: for the effective confrontation of the ethical problems experienced by oncology nurses to occur, it is important to invest in the training of these professionals, preparing them in an ethical and human way to act as lawyers of the patient with cancer, in a context of dilemmas related mainly to the possibility of finitude.

    Objective The objective of the study was to investigate medication usage patterns, health care resource utilization, and direct medical costs of patients with major depressive disorder (MDD) in Beijing, People’s Republic of China. Methods Data were extracted from a random sample of the Beijing Urban Employee Basic Medical Insurance database. Patients aged ≥18 years, with ≥1 primary diagnosis of MDD and 12-month continuous enrollment after their first observed MDD diagnosis between 2012 and 2013 were identified. Those with a diagnosis of schizophrenia, bipolar disorder, or cancer during the analysis period were excluded. Results In total 8,484 patients, with a mean age of 57.2 years, were included and 63% were female. The top three commonly observed comorbidities were hypertension (70.9%), anxiety disorder (68.6%), and coronary heart disease (65.1%). Furthermore, 71.4% of patients were treated with antidepressant medications, including 60.5% of patients treated with selective serotonin reuptake inhibitors, followed by noradrenergic and specific serotonergic antidepressants (9.0%) and serotonin–norepinephrine reuptake inhibitors (8.3%). The proportions of patients who discontinued their initial antidepressant within the first and second months after the index date were 45.4% and 77.0%, respectively. Concomitant medications were prescribed for 76.8% of patients. Only 0.42% of patients experienced ≥1 MDD-related hospitalization(s) during the 1-year follow-up, and the average annual number of hospitalization was 1.2 for those hospitalized. The mean length of stay was 33.4 days per hospitalization. All patients had ≥1 MDD-related outpatient visit(s). The mean annual number of outpatient visits per patient was 3.1. The mean annual direct medical costs per patient with MDD was RMB ¥1,694.1 (48.5% for antidepressant medications), and that for hospitalized patients was RMB ¥21,291.0 (15.0% for antidepressant medications). Conclusion In Beijing, the majority of

    To describe utilization of a biosimilar product containing filgrastim (Neutromax), data of 414 myeloma or lymphoma patients subjected to autologous SCT between 1998 and 2007 were analyzed. Filgrastim was used for mobilization of progenitors (5 days at 300 microg/day) and for the recovery of neutropenia after transplantation (100 microg/day, since day +5). In 2003, the excipient mannitol was replaced by sorbitol. A mean dose of 9.47 x 10(6)CD34(+)cells/kg was infused; 100 neutrophils/mm(3) required 5-day treatment; 500 neutrophils/mm(3), 6 days and 1000 neutrophils/mm(3), 7 days. Neutromax effect in SCT is similar to reports with other brands. No difference was found between formulations. PMID:19699152

    Buprenorphine-medication assisted therapy (B-MAT) is an effective treatment for opioid dependence, but may be considered cost-prohibitive based on ingredient cost alone. The purpose of this study was to use medical and pharmacy claims data to estimate the healthcare service utilization and costs associated with B-MAT adherence among a sample of opioid dependent members. Members were placed into two adherence groups based on 1-year medication possession ratio (≥ 0.80 vs. <0.80). The B-MAT adherent group incurred significantly higher pharmacy charges (adjusted means; $6,156 vs. $3,581), but lower outpatient ($9,288 vs. $14,570), inpatient ($10,982 vs. $26,470), ER ($1,891 vs. $4,439), and total healthcare charges ($28,458 vs. $49,051; p<0.01) compared to non-adherent members. Adherence effects were confirmed in general linear models. Though B-MAT adherence requires increased pharmacy utilization, adherent individuals were shown to use fewer expensive health care services, resulting in overall reduced healthcare expenditure compared to non-adherent patients.

    Bisphosphonates are the most widely prescribed treatment for postmenopausal osteoporosis, secondary osteoporosis, and male osteoporosis. Notwithstanding their high effectiveness and favorable safety profile, the adherence to bisphosphonate treatment remains low. Different treatment strategies aim to improve the clinical effectiveness of bisphosphonate therapy. This review paper assesses the clinical utility of oral intermittent risedronate in the treatment of postmenopausal osteoporosis. The new delayed-release risedronate formulation is a safer and easy to use alternative to other risedronate therapy. Oral risedronate, a potent nitrogen-containing bisphosphonate, has been extensively studied using daily regimens. A new intermittent (weekly) dosing regimen confirmed its clinical effectiveness in relation to vertebral and nonvertebral fracture prevention. The absence of significant differences in the incidence of adverse effects confirmed the favorable tolerability of the weekly dosage. In efforts to improve patient adherence to treatment, an innovative, delayed-release formulation of risedronate, which ensures adequate bioavailability of the active compound when taken with food, was introduced. The once-weekly delayed-release formulation of risedronate proved to be noninferior to the daily dosage of risedronate in terms of bone mineral density and markers of bone turnover. In addition, the incidence of new morphometric vertebral fractures was comparable in both treatment regimens. The new delayed-release formulation of risedronate showed a favorable safety profile. Delayed-release risedronate is a promising, new, effective, and convenient alternative to current bisphosphonate treatments. It appears to allow better patient adherence to antiresorptive treatment.

    Current DSM-based instruments for personality disorders (PDs) limit the investigation of the course and outcome of treatment of these disorders. This study examined the validity of the Shedler-Westen Assessment Procedure-200 (SWAP-200) and the Structured Clinical Interview for DSM-IV Axis II PD (SCID-II) in a sample of forensic PD patients. Results based on 66 participants indicated that the SWAP-200 Q-factors reduced the frequency of diagnostic comorbidity of PD categories by half compared with the SCID-II. Only the SWAP-200's Antisocial PD category showed good convergent and discriminant validity with respect to other instruments describing aspects of PD. The validity of the cutoff score for severe antisocial PD was confirmed, and this category predicted severe incidents in the hospital at 1 year of follow-up. A violence risk scale was constructed, which differentiated violent and nonviolent offenders. The results support the validity of the SWAP-200 and its potential clinical utility with forensic PD patients. PMID:24511901

  5. How Well Do the Generic Multi-attribute Utility Instruments Incorporate Patient and Public Views Into Their Descriptive Systems?

    2016-02-01

    Multi-attribute utility instruments (MAUIs) are increasingly being used to generate utility data, which can be used to calculate quality-adjusted life-years (QALYs). These QALY data can then be incorporated into a cost-utility analysis as part of an economic evaluation, to inform health care resource allocation decisions. Many health care decision-making bodies around the world, such as the National Institute for Health and Care Excellence, require the use of generic MAUIs. Recently, there has been a call for greater input of patients into the development of patient-reported outcome measures, and this is now actively encouraged. By incorporating the views of patients, greater validity of an instrument is expected and it is more likely that patients will be able to self-complete the instrument, which is the ideal when obtaining information about a patient's health-related quality of life. This paper examines the stages of MAUI development and the scope for patient and/or public involvement at each stage. The paper then reviews how much the main generic MAUIs have incorporated the views of patients/the public into the development of their descriptive systems at each of these stages, and the implications of this. The review finds that the majority of MAUIs had very little input from patients/the public. Instead, existing literature and/or the views of experts were used. If we wish to incorporate patient/public views into future development of MAUIs, qualitative methods are recommended. PMID:25663152

    AIM: To investigate the diagnostic yield, therapeutic efficacy, and rate of adverse events related to flexible fiberoptic bronchoscopy (FFB) in critically ill children. METHODS: We searched PubMed, SCOPUS, OVID, and EMBASE databases through July 2014 for English language publications studying FFB performed in the intensive care unit in children < 18 years old. We identified 666 studies, of which 89 full-text studies were screened for further review. Two reviewers independently determined that 27 of these studies met inclusion criteria and extracted data. We examined the diagnostic yield of FFB among upper and lower airway evaluations, as well as the utility of bronchoalveolar lavage (BAL). RESULTS: We found that FFB led to a change in medical management in 28.9% (range 21.9%-69.2%) of critically ill children. The diagnostic yield of FFB was 82% (range 45.2%-100%). Infectious organisms were identified in 25.7% (17.6%-75%) of BALs performed, resulting in a change of antimicrobial management in 19.1% (range: 12.2%-75%). FFB successfully re-expanded atelectasis or removed mucus plugs in 60.3% (range: 23.8%-100%) of patients with atelectasis. Adverse events were reported in 12.9% (range: 0.5%-71.4%) of patients. The most common adverse effects of FFB were transient hypotension, hypoxia and/or bradycardia that resolved with minimal intervention, such as oxygen supplementation or removal of the bronchoscope. Serious adverse events were uncommon; 2.1% of adverse events required intervention such as bag-mask ventilation or intubation and atropine for hypoxia and bradycardia, normal saline boluses for hypotension, or lavage and suctioning for hemorrhage. CONCLUSION: FFB is safe and effective for diagnostic and therapeutic use in critically ill pediatric patients. PMID:25685726

    Delaying treatment for benign musculoskeletal conditions may allow patients to learn self-efficacy and develop coping strategies, leading to less medical intervention and reduced cost. We tested the hypothesis that time from booking until appointment is not associated with healthcare costs. We further tested the secondary hypothesis that time from booking to appointment is not associated with specific healthcare utilizations. We identified 16,750 patients (55 % women; mean age 50 years) making first clinic visits to hand surgeons at our hospital between January 1, 2003 and December 31, 2012. Booking time was defined as the time between the scheduling of an appointment and the actual visit. Imaging procedures, injections, nerve conduction studies, occupational therapy visits, surgery, and referrals were determined up until the patient's second visit with the surgeon, or 90 days. Costs were determined in Relative Value Units. Duration between booking and office visit was not associated with higher cost (regression coefficient [β] 0.0023, P = 0.77). Duration between booking and office visit was associated with a higher rate of nerve conduction studies (odds ratio [OR] 1.02, P < 0.001) and a lower rate of occupational therapy (OR 0.98, P < 0.001). There was substantial variation between surgeons. Greater wait time was not therapeutic, but is associated with different diagnostic and treatment measures that suggest people that are willing to wait have different types of problems. The variation by surgeon may make variation based on other factors, including time between booking and appointment, difficult to discern. PMID:26578829

    Many US combat personnel have sustained nervous tissue trauma during service, which often causes Neuropathic pain as a side effect and is difficult to manage. However in select patients, synapse lesioning can provide significant pain control. Our goal is to determine the effectiveness of using Proton Beam radiotherapy for treating spinal cord injury (SCI) related neuropathic pain as an alternative to invasive surgical lesioning. The project is a joint collaboration of USC, Spinal Cord Institute VA Healthcare System, Long Beach, and Loma Linda University. This is first system of its kind that supports integration and standardization of imaging informatics data in DICOM format; clinical evaluation forms outcomes data and treatment planning data from the Treatment planning station (TPS) utilized to administer the proton therapy in DICOM-RT format. It also supports evaluation of SCI subjects for recruitment into the clinical study, which includes the development, and integration of digital forms and tools for automatic evaluation and classification of SCI pain. Last year, we presented the concept for the patient recruitment module based on the principle of Bayesian decision theory. This year we are presenting the fully developed patient recruitment module and its integration to other modules. In addition, the DICOM module for integrating DICOM and DICOM-RT-ION data is also developed and integrated. This allows researchers to upload animal/patient study data into the system. The patient recruitment module has been tested using 25 retrospective patient data and DICOM data module is tested using 5 sets of animal data.

  9. a Structure of Experienced Time

    Havel, Ivan M.

    2005-10-01

    The subjective experience of time will be taken as a primary motivation for an alternative, essentially discontinuous conception of time. Two types of such experience will be discussed, one based on personal episodic memory, the other on the theoretical fine texture of experienced time below the threshold of phenomenal awareness. The former case implies a discrete structure of temporal episodes on a large scale, while the latter case suggests endowing psychological time with a granular structure on a small scale, i.e. interpreting it as a semi-ordered flow of smeared (not point-like) subliminal time grains. Only on an intermediate temporal scale would the subjectively felt continuity and fluency of time emerge. Consequently, there is no locally smooth mapping of phenomenal time onto the real number continuum. Such a model has certain advantages; for instance, it avoids counterintuitive interpretations of some neuropsychological experiments (e.g. Libet's measurement) in which the temporal order of events is crucial.

    Background and objectives Older adults with ESRD often receive care in skilled nursing facilities (SNFs) after an acute hospitalization; however, little is known about acute care use after SNF discharge to home. Design, setting, participants, & measurements This study used Medicare claims for North and South Carolina to identify patients with ESRD who were discharged home from a SNF between January 1, 2010 and August 31, 2011. Nursing Home Compare data were used to ascertain SNF characteristics. The primary outcome was time from SNF discharge to first acute care use (hospitalization or emergency department visit) within 30 days. Cox proportional hazards models were used to identify patient and facility characteristics associated with the outcome. Results Among 1223 patients with ESRD discharged home from a SNF after an acute hospitalization, 531 (43%) had at least one rehospitalization or emergency department visit within 30 days. The median time to first acute care use was 37 days. Characteristics associated with a shorter time to acute care use were black race (hazard ratio [HR], 1.25; 95% confidence interval [95% CI], 1.04 to 1.51), dual Medicare-Medicaid coverage (HR, 1.24; 95% CI, 1.03 to 1.50), higher Charlson comorbidity score (HR, 1.07; 95% CI, 1.01 to 1.12), number of hospitalizations during the 90 days before SNF admission (HR, 1.12; 95% CI, 1.03 to 1.22), and index hospital discharge diagnoses of cellulitis, abscess, and/or skin ulcer (HR, 2.59; 95% CI, 1.36 to 4.45). Home health use after SNF discharge was associated with a lower rate of acute care use (HR, 0.72; 95% CI, 0.59 to 0.87). There were no statistically significant associations between SNF characteristics and time to first acute care use. Conclusions Almost one in every two older adults with ESRD discharged home after a post–acute SNF stay used acute care services within 30 days of discharge. Strategies to reduce acute care utilization in these patients are needed. PMID:25649158

    Ensuring patient safety and enhancing nurse satisfaction both rank high on most hospitals' list of priorities. One of the concerns at a large, comprehensive, county health care system in the southwestern United States has been the shortage of experienced obstetrics (OB) nurses to provide patient care. To address this concern, a nursing fellowship was implemented to facilitate successful transition and retention of experienced RNs into the specialty area of obstetrics. The program provided a gateway for non-OB nurses to participate in relevant, evidence-based didactic and preceptor-facilitated clinical experiences to ensure adequate knowledge, skills, and competencies to care for patients in labor, delivery, and recovery suites.

    Background: The beneficial effects of endovascular treatment with new-generation mechanical thrombectomy devices compared with intravenous thrombolysis alone to treat acute large-artery ischemic stroke have been shown in randomized controlled trials (RCTs). This study aimed to estimate the cost utility of mechanical thrombectomy compared with the established standard of care. Methods: We developed a Markov decision process analytic model to assess the cost-effectiveness of treatment with mechanical thrombectomy plus intravenous thrombolysis versus treatment with intravenous thrombolysis alone from the public payer perspective in Canada. We conducted comprehensive literature searches to populate model inputs. We estimated the efficacy of mechanical thrombectomy plus intravenous thrombolysis from a meta-analysis of 5 RCTs, and we used data from the Oxford Vascular Study to model long-term clinical outcomes. We calculated incremental cost-effectiveness ratios (ICER) using a 5-year time horizon. Results: The base case analysis showed the cost and effectiveness of treatment with mechanical thrombectomy plus intravenous thrombolysis to be $126 939 and 1.484 quality-adjusted life-years (QALYs), respectively, and the cost and effectiveness of treatment with intravenous thrombolysis alone to be $124 419 and 1.273 QALYs, respectively. The mechanical thrombectomy plus intravenous thrombolysis strategy was associated with an ICER of $11 990 per QALY gained. Probabilistic sensitivity analysis showed that the probability of treatment with mechanical thrombectomy plus intravenous thrombolysis being cost-effective was 57.5%, 89.7% and 99.6% at thresholds of $20 000, $50 000 and $100 000 per QALY gained, respectively. The main factors influencing the ICER were time horizon, extra cost of mechanical thrombectomy treatment and age of the patient. Interpretation: Mechanical thrombectomy as an adjunct therapy to intravenous thrombolysis is cost-effective compared with

    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

    We assessed whether an Assertive Outreach (AO) program for patients with schizophrenia implemented in German routine care in rural areas reduces psychiatric hospital admissions and/or psychiatric hospital days. We conducted a quasi-experimental controlled study with 5 assessments in 12 months. Data collection included health care utilization (Client Sociodemographic and Service Receipt Inventory), and clinical parameters. The assessments took place in the practices of the psychiatrists. Admission incidence rates were calculated. For bivariate group comparison, we used U-tests, T-tests and Chi(2)-Tests, multivariate analysis was conducted using zero-inflated regression models. For hospital outcomes, data of 295 patients was analysed. No statistically significant differences between AO and TAU patients in terms of hospital admissions or hospital days were found. Overall hospital utilization was low (8%). Advantages of AO over TAU referring to hospital utilization were not found. However, a spill-over effect might have reduced hospital utilization in both groups. Further research should differentiate patient subgroups. These two appear to be key factors to explain effects or absence of effects and to draw conclusions for the mental health care delivery. PMID:27208511

    Obscure overt gastrointestinal bleeding (OGIB) is a challenge in patients with left ventricular assist devices (LVADs). We evaluated the utility and safety of double-balloon enteroscopy (DBE) in patients with LVADs in an observational consecutive-patient cohort from a single tertiary referral center. Ten patients with LVADs underwent thirteen DBEs for obscure OGIB. The first OGIB event necessitating DBE occurred after a mean of 512 ± 363 days of LVAD support. All patients underwent DBE, eleven anterograde and two retrograde, with a mean insertion depth 176 ± 85 cm. Diagnostic yield was 69 % with the primary bleeding lesion most frequently found in the mid-bowel. The most common lesions were arteriovenous malformations. Therapeutic yield with argon plasma coagulation (APC), epinephrine injection, and/or hemoclip placement was 89 %. There were no procedure-related complications. DBE in patients with LVADs has good diagnostic yield and high therapeutic yield for obscure OGIB and is safe and well tolerated. PMID:25290096

    Heart Failure continues to be a major public health problem associated with high mortality and morbidity. Heart Failure is the leading cause of hospitalization for persons older than 65 years, has a poor prognosis and is associated with poor quality of life. More than 5.3 million American adults are living with heart failure. Despite maximum medical therapy and frequent hospitalizations to stabilize their condition, one in five heart failure patients die within the first year of diagnosis. Several disease-management programs have been proposed and tested to improve the quality of heart failure care. Studies have shown that hospital admissions and emergency room visits decrease with increased nursing interventions in the home and community setting. An alternative strategy for promoting self-management of heart failure is the use of electronic home monitoring. The purpose of this study was to examine what effects heart failure has on patient's quality of life that had been monitoring on an electronic home monitor longer than 2 months. Twenty-one questionnaires were given to patients utilizing an electronic home monitor by their home health agency nurse. Eleven patients completed the questionnaire. The findings showed that there is some deterioration in quality of life with more association with the physical aspects of life than with the emotional aspects of life, which probably was due to the small sample size. There was no significant difference in readmission rates in patients utilizing an electronic home monitor. Further research is needed with a larger population of patients with chronic heart failure and other chronic diseases which may provide more data, and address issues such as patient compliance with self-care, impact of heart failure on patient's quality of life, functional capacity, and heart failure patient's utilization of the emergency rooms and hospital. Telemonitoring holds promise for improving the self-care abilities of persons with HF.

    Abstract The Brunnstrom recovery stages (the BRS) consists of 2 items assessing the poststroke motor function of the upper extremities and 1 assessing the lower extremities. The 3 items together represent overall motor function. Although the BRS efficiently assesses poststroke motor functions, a lack of rigorous examination of the psychometric properties restricts its utility. We aimed to examine the unidimensionality, Rasch reliability, and responsiveness of the BRS, and transform the raw sum scores of the BRS into Rasch logit scores once the 3 items fitted the assumptions of the Rasch model. We retrieved medical records of the BRS (N = 1180) from a medical center. We used Rasch analysis to examine the unidimensionality and Rasch reliability of both upper-extremity items and the 3 overall motor items of the BRS. In addition, to compare their responsiveness for patients (n = 41) assessed with the BRS and the Stroke Rehabilitation Assessment of Movement (STREAM) on admission and at discharge, we calculated the effect size (ES) and standardized response mean (SRM). The upper-extremity items and overall motor items fitted the assumptions of the Rasch model (infit/outfit mean square = 0.57–1.40). The Rasch reliabilities of the upper-extremity items and overall motor items were high (0.91–0.92). The upper-extremity items and overall motor items had adequate responsiveness (ES = 0.35–0.41, SRM = 0.85–0.99), which was comparable to that of the STREAM (ES = 0.43–0.44, SRM = 1.00–1.13). The results of our study support the unidimensionality, Rasch reliability, and responsiveness of the BRS. Moreover, the BRS can be transformed into an interval-level measure, which would be useful to quantify the extent of poststroke motor function, the changes of motor function, and the differences of motor functions in patients with stroke.

    Background Secretory phospholipase A2 (sPLA2) may contribute to atherogenesis. To date, few prospective studies have examined the utility of sPLA2 for risk stratification in coronary artery disease (CAD). Methods Plasma sPLA2 activity was measured at baseline in 3708 subjects in the PEACE randomized trial of trandolapril versus placebo in stable CAD. Median follow-up was 4.8 years. Cox regression was used to adjust for demographics, clinical risk factors, apolipoprotein B, apolipoprotein A1, and medications. Results After multivariable adjustment, sPLA2 was associated with an increased risk of cardiovascular death, myocardial infarction or stroke (adjusted hazard ratio quartile 4:quartile 1 1.55, 95% CI 1.13–2.14) and cardiovascular death or heart failure (adjusted hazard ratio quartile 4:quartile 1 1.91, 95% CI 1.20–3.03). In further multivariable assessment, increased activities of sPLA2 were associated with the risk of cardiovascular death, myocardial infarction or stroke (adjusted hazard ratio 1.47, 95% CI 1.06–2.04) independent of lipoprotein-associated phospholipase A2 mass and C-reactive protein, and modestly improved the area under the curve (AUC) beyond established clinical risk factors (AUC 0.668 to 0.675, P=0.01). sPLA2, NT-pro B-type natriuretic peptide and high-sensitivity cardiac troponin T were all independently associated with cardiovascular death or heart failure and each improved risk discrimination (P=0.02, P<0.001, P<0.001, respectively). Conclusion sPLA2 activity provides independent prognostic information beyond established risk markers in patients with stable CAD. These data are encouraging for studies designed to evaluate the role of sPLA2 as a therapeutic target. PMID:21784767

    Background The optimization of medication use during care transitions represents an opportunity to improve overall health-related outcomes. The utilization of clinical pharmacists during care transitions has demonstrated benefit, although the optimal method of integration during the care transition process remains unclear. Objective To evaluate the impact of pharmacist-provided telephonic medication therapy management (MTM) on care quality in a care transitions program (CTP) for high-risk older adults. Methods This prospective, randomized, controlled study was conducted from December 8, 2011, through October 25, 2012, in a primary care work group at a tertiary care academic medical center in the midwestern United States. High-risk elderly (aged ≥60 years) patients were randomized to a pharmacist-provided MTM program via telephone or to usual care within an existing outpatient CTP. The primary outcome was the quality of medication prescribing and utilization based on the Screening Tool to Alert Doctors to the Right Treatment (START) and the Screening Tool of Older Persons’ Prescriptions (STOPP) scores. The secondary outcomes were medication utilization using a modified version of the Medication Appropriateness Index, hospital resource utilization within 30 days of discharge, and drug therapy problems. Results Of 222 eligible high-risk patients, 25 were included in the study and were randomized to the pharmacist MTM intervention (N = 13) or to usual care (N = 12). No significant differences were found between the 2 groups in medications meeting the STOPP or START criteria. At 30-day follow-up, no significant differences were found between the 2 cohorts in medication utilization quality indicators or in hospital utilization. At 30-day follow-up, 3 (13.6%) patients had an emergency department visit or a hospital readmission since discharge. In all, 22 patients completed the study. Medication underuse was common, with 20 START criteria absent medications evident for

    Hennepin County Medical Center in Minneapolis, MN, has developed a new model of care, designed to meet the needs of high-utilizing hospital and ED patients with complex medical, social, and behavioral needs.The Coordinated Care Center (CCC) provides easy access to patients with a history of high utilization, and delivers multidisciplinary care in a one-stop-shop format. In one year, the approach has slashed ED visits by 37%, freeing up emergency providers to focus on patients with acute needs. In-patient care stays are down by 25%. The CCC focuses on patients with diagnoses that are primarily medical, such as CHF [congestive heart failure], COPD [chronic obstructive pulmonary disease], or diabetes. ED-based clinical coordinators keep an eye out for patients who world be good candidates for the CCC, and facilitate quick transitions when their needs would be better served in that setting. Administrators describe CCC as an ambulatory intensive care unit, with an on-site pharmacist, social worker, psychologist, and chemical health counselor as well as physicians, nurse practitioners, LPNs, and patient navigators--enough personnel to comprise two full care teams. While the model does not pay for itself under current payment models, administrators anticipate that the approach will work well under future payment reforms that focus on total cost of care.

    Background Syncope in elderly patients with heart disease is a growing problem. Its aetiological diagnosis is often difficult. We intended to investigate the value of the electrophysiological study (EPS) in old patients with syncope and heart disease. Methods EPS was performed in 182 consecutive patients with syncope and heart disease, among whom 62 patients were ≥75 years old and 120 patients <75. Results Left ventricular ejection fraction was 43.9±11.7% in patients ≥75 and 41.1±12.6% in patients <75. During EPS, induced sustained ventricular arrhythmias were as frequent in both groups (27.4% in patients ≥75 versus 27.5% in patients <75, p=0.99) whereas AV conduction abnormalities were more frequent in older patients (37.1% in patients ≥75 versus 18.3% in patients<75, p<0.005). Syncope remained unexplained in 35.5% of patients ≥75 and in 51.7% of patients <75 (p<0.04). ICD was more likely to be implanted in younger patients than in patients ≥75 years (37.5% vs 21% respectively, p<0.009). During a mean follow-up period of 3.3±3 years, the 4-year-survival rate was 66.9±6.8 % in patients ≥75 and 75.9±6.2 % in patients <75 years. The main cause of death was heart failure in both groups. The factors related to a worse outcome in a multivariate analysis were low LVEF and higher age. Conclusion Complete EPS allows the identification of treatable causes in a high proportion of elderly patients with syncope and heart disease. Yet, the prognosis of these patients is mainly related to LVEF and age. PMID:25852241

    Background Trauma exposure and post-traumatic stress disorder (PTSD) increase healthcare utilization in veterans, but their impact on utilization in other populations is uncertain. Objectives To examine the association of trauma exposure and PTSD with healthcare utilization, in civilian primary care patients. Research Design Cross-sectional study. Subjects English speaking patients at an academic, urban primary care clinic. Measures Trauma exposure and current PTSD diagnoses were obtained from the Composite International Diagnostic Interview. Outcomes were nonmental health outpatient and emergency department visits, hospitalizations, and mental health outpatient visits in the prior year from an electronic medical record. Analyses included bivariate unadjusted and multivariable Poisson regressions adjusted for age, gender, income, substance dependence, depression, and comorbidities. Results Among 592 subjects, 80% had ≥1 trauma exposure and 22% had current PTSD. In adjusted regressions, subjects with trauma exposure had more mental health visits [incidence rate ratio (IRR), 3.9; 95% confidence interval (CI), 1.1–14.1] but no other increased utilization. After adjusting for PTSD, this effect of trauma exposure was attenuated (IRR, 3.2; 95% CI, 0.9–11.7). Subjects with PTSD had more hospitalizations (IRR, 2.2; 95% CI, 1.4–3.7), more hospital nights (IRR, 2.6; 95% CI, 1.4–5.0), and more mental health visits (IRR, 2.2; 95% CI, 1.1–4.1) but no increase in outpatient and emergency department visits. Conclusions PTSD is associated with more hospitalizations, longer hospitalizations, and greater mental healthcare utilization in urban primary care patients. Although trauma exposure is independently associated with greater mental healthcare utilization, PTSD mediates a portion of this association. PMID:18362818

    Prescribing safe and effective medications is a challenge in psychiatry. While clinical use of pharmacogenomic testing for individual genes has provided some clinical benefit, it has largely failed to show clinical utility. However, pharmacogenomic testing that integrates relevant genetic variation from multiple loci for each medication has shown clinical validity, utility and cost savings in multiple clinical trials. While some challenges remain, the evidence for the clinical utility of "combinatorial pharmacogenomics" is mounting. Expanding education of pharmacogenomic testing is vital to implementation efforts in psychiatric treatment settings with the overall goal of improving medication selection decisions. PMID:26937360

    The orientation period creates a context for a nurse’s relationship with her employer, and can adversely affect attrition rates. While the orientation needs of novice nurses have been detailed, little is known about what might help those with prior experience. Hence, the goal of this study was to explore whether the orientation needs of seasoned nurses are similar to or unique from novice nurses. Over a six month period, we used two intensive qualitative methodologies (daily journaling and focus groups) to study three experienced nurses. A tri-phased model of orientation emerged, with learning and support issues unique to experienced nurses identified. Results suggest that orientation programs for experienced nurses should utilize specific educational strategies and content to promote engagement in a new position. PMID:19639852

    2013-01-01

    Background Type 2 diabetes is a common and costly illness, associated with significant morbidity and mortality. Despite this, there is relatively little information on the ‘real-world’ medication utilization patterns for patients with type 2 diabetes initiating exenatide BID or glargine. The objective of this study was to evaluate the ‘real-world’ medication utilization patterns in patients with type 2 diabetes treated with exenatide BID (exenatide) versus insulin glargine (glargine). Methods Adult patients( ≥18 years of age) with type 2 diabetes who were new initiators of exenatide or glargine from October 1, 2006 through March 31, 2008 with continuous enrollment for the 12 months pre- and 18 months post-index period were selected from the MarketScan® Commercial and Medicare Databases. To control for selection bias, propensity score matching was used to complete a 1:1 match of glargine to exenatide patients. Key study outcomes (including the likelihood of overall treatment modification, discontinuation, switching, or intensification) were analyzed using survival analysis. Results A total of 9,197 exenatide- and 4,499 glargine-treated patients were selected. Propensity score matching resulted in 3,774 matched pairs with a mean age of 57 years and a mean Deyo Charlson Comorbidity Index score of 1.6; 54% of patients were males. The 18-month treatment intensification rates were 15.9% and 26.0% (p < 0.0001) and the discontinuation rates were 38.3% and 40.0% (p = 0.14) for exenatide and glargine, respectively. Alternatively, 14.9% of exenatide-treated patients switched therapies, compared to 10.0% of glargine-treated patients (p < 0.0001). Overall, glargine-treated patients were more likely to modify their treatment [hazard ratio (HR) = 1.33, p < 0.0001] with shorter mean time on treatment until modification (123 vs. 159 days, p < 0.0001). Compared to exenatide-treated patients, glargine-treated patients were more likely to

    We surveyed 150 methadone maintenance treatment program (MMTP) patients about pain, pain treatment utilization, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment at the MMTP. Respondents with chronic severe pain (CSP) (i.e., pain lasting at least 6 months with moderate to severe pain intensity or significant pain interference) and “some pain” (i.e., pain reported in the previous week but not CSP) endorsed similar rates of past-week and lifetime allopathic or standard medical (with the exception of lifetime medical use of non-opiate medication) and complementary and alternative medicine (CAM) utilization for pain reduction. Prior pain treatments were perceived to be less effective by CSP than SP patients but both groups had equivalent high rates of interest in pain treatment associated with the MMTP. These findings may have implications for resource and program planning in MMT programs. PMID:19874157

    OBJECTIVE: To evaluate the prevalence of gastroesophageal reflux disease (GERD) in patients presenting with asthma and chronic cough. PATIENTS AND METHODS: The charts of 358 consecutive patients who were referred for ambulatory gastroesophageal pH monitoring to the Lung Centre in Vancouver, British Columbia, were reviewed, and the data of 108 (30%) patients with asthma and 134 (37%) patients with chronic cough were analyzed. The maintenance treatment for GERD was discontinued before patients underwent the pH monitoring study. One hundred eighteen (33%) patients were excluded. RESULTS: Reflux episodes identified reflux events as the percentage of time where the pH was less than four. For asthma patients, 70 (64.8%) had distal total reflux, 50 (46.3%) had distal upright reflux, 41 (38.3%) had distal supine reflux and 73 (67.6%) had other distal refluxes. Proximal total reflux in asthmatic patients was present in 56 (52%), proximal upright reflux in 55 (51%) and proximal supine reflux in 56 (52%) patients. For chronic cough patients, 70 (52.6%) had distal total reflux, 59 (44.4%) had distal upright reflux, 45 (34.4%) had distal supine reflux and 75 (56%) patients had other distal refluxes. In chronic cough patients, proximal total reflux was present in 70 (52%), proximal upright reflux in 80 (60%) and proximal supine reflux in 59 (44%). Presenting respiratory and/or reflux symptoms were absent in approximately 25% of patients with asthma and reflux, and in approximately 50% of patients with chronic cough and reflux. During pH monitoring, symptoms did not differ significantly between those with and without distal reflux in both study groups, except for more significant heartburn in patients with chronic cough and reflux (RR 2.0). CONCLUSIONS: The data of the present study support the observation that there is a high prevalence of GERD in patients with asthma or chronic cough.

    Caregivers are known to experience increased morbidity when compared to noncaregivers. Does an intervention targeting caregiver distress affect their health care utilization? One hundred forty-eight caregivers of allogeneic hematopoietic stem cell transplant patients were randomized to treatment as usual (TAU) or a psychoeducation, paced respiration, and relaxation (PEPRR) intervention. Assessments of caregivers' service utilization were collected at baseline and 1, 3, and 6 months post-transplant. During the first 30 days after patient transplant, caregiver medical and mental health professional service use decreased while support group attendance peaked. Mixed model regressions showed a significant decrease in mental health service use by the PEPRR group (P=0.001). At six months caregivers in TAU had predicted marginal probabilities of mental health services utilization over 10 times as high as caregivers in PEPRR (18.1% vs 1.5%). Groups failed to differ in medical service (P=0.861) or support group (P=0.067) use. We can conclude that participation in PEPRR compared to TAU was associated with reduced mental health service utilization. Caregiver psychosocial support services are critical to improve caregiver outcomes. PMID:25478136

    Background. In China, the use of traditional Chinese medicine (TCM) is very popular, but little is known about how it is integrated with conventional cancer care. We conducted parallel surveys of patients and physicians on TCM utilization. Methods. Two hundred forty-five patients and 72 allopathic physicians at the Fudan University Shanghai Cancer Center completed questions on their use of and attitude towards TCM. Results. Patient mean age was 51, with 60% female. Eighty-three percent of patients had used TCM. Use was greatest for Chinese herbal medicine (CHM; 55.8%). Only 1.3% of patients used acupuncture and 6.8% Qi Gong or Tai Qi. Sixty-three percent of patients notified their oncologist about TCM use. The most common reason for use was to improve immune function. CHM was often used with a goal of treating cancer (66.4%), a use that 57% of physicians agreed with. Physicians were most concerned with interference with treatment, lack of evidence, and safety. Ninety percent of physicians have prescribed herbs and 87.5% have used TCM themselves. Conclusion. The use of TCM by Chinese cancer patients is exceptionally high, and physicians are generally well informed and supportive of patients' use. Botanical agents are much more commonly used than acupuncture or movement-based therapies. PMID:23093982

    Background Chemotherapy-induced nausea and vomiting (CINV) can lead to increased emergency department visits and hospitalizations, which may contribute to increased cost of care. Antiemetic agents, such as neurokinin-1 (NK1) receptor antagonists and 5-hydroxytryptamine (5-HT3) receptor antagonists, are prescribed for patients receiving highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC). The current guidelines recommend a 3-drug combination of an NK1 receptor antagonist, a 5-HT3 receptor antagonist, and dexamethasone with HEC regimens and certain MEC regimens. Objective To compare the incidence of CINV and CINV-related resource utilization among patients who receive guideline-adherent HEC and MEC regimens and patients who receive non–guideline-adherent regimens. Methods In this retrospective, claims-based study, Inovalon's Medical Outcomes Research for Effectiveness and Economics Registry (MORE2 Registry) Research Edition database was used to identify 8089 patients with solid tumors receiving therapy with anthracycline plus cyclophosphamide (AC), cisplatin, or carboplatin from June 2013 to December 2013. The patients were stratified according to the use of an NK1 receptor antagonist regimen. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify CINV events associated with hospital, emergency department, and outpatient office visits among patients in the NK1 receptor antagonist group and the non-NK1 receptor antagonist group. Results A total of 1059 patients were included in the analysis, of whom 51% (N = 536) used an NK1 receptor antagonist–based regimen and 49% (N = 523) used non-NK1 receptor antagonist therapy. A higher percentage of patients receiving AC (73%) than cisplatin (56%) or carboplatin (23%) received an NK1 receptor antagonist. The incidence rates of total CINV events and CINV-related emergency department visits were lower in the group receiving an NK1 receptor

    The purpose of the current study was to examine the clinical utility of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 2000) and the Five Factor Model of personality disorder (FFM; Widiger, Costa, & McCrae, 2002) in describing personality pathology. In the current study, practicing psychologists described one or two of their personality disordered patients in terms of the FFM and DSM models. In some instances, the patient was someone who met the criteria for one of the 10 DSM-IV personality disorders; in others, the patient was someone who received a diagnosis of personality disorder, not otherwise specified. Participants then rated each model on six aspects of clinical utility. The current study found that the FFM was consistently rated higher than the DSM model in terms of four of the six aspects of clinical utility. Across both cases, the clinicians rated the FFM as significantly more useful with respect to its ability to provide a global description of the individual's personality, to communicate information to clients, and to encompass all of the individual's important personality difficulties.

    Objective The aim of the study was to examine the effectiveness of an intensive inpatient three-week multimodal therapy. We focused especially on the impact on the multimodal therapy outcome of the pre-admission number of treatment types patients had received and of medical specialist groups patients had consulted. Methods 155 patients with chronic low back pain and indication for multimodal therapy were evaluated with respect to pain intensity, depression, anxiety, well-being, and pre-admission health care utilization. In our controlled clinical trial we compared N = 66 patients on the waiting list with N = 89 patients who received immediate treatment. The waiting list patients likewise attended multimodal therapy after the waiting period. Longitudinal post-treatment data for both were collected at three- and twelve-month follow-ups. The impact of pre-admission health care utilization on multimodal therapy outcome (post) was analysed by structural equation model. Results Compared to the control group, multimodal therapy patients’ pain intensity and psychological variables were significantly reduced. Longitudinal effects with respect to pre-measures were significant at three-month follow-up for pain intensity (ES = -0.48), well-being (ES = 0.78), anxiety (ES = -0.33), and depression (ES = -0.30). Effect sizes at twelve-month follow-up were small for anxiety (ES = -0.22), and moderate for general well-being (ES = 0.61). Structural equation model revealed that a higher number of pre-admission treatment types was associated with poorer post-treatment outcomes in pain intensity, well-being, and depression. Conclusion Multimodal therapy proved to be effective with regard to improvements in pain intensity, depression, anxiety, and well-being. The association between treatment effect and number of pre-admission pain treatment types suggests that patients would benefit more from attending multimodal therapy in an earlier stage of health care.

    Aim: To evaluate the use of potentially inappropriate medicines in elderly inpatients in a tertiary care teaching hospital. Materials and Methods: Retrospective analysis was performed for cases of elderly patients admitted between January 2010 and December 2010. Data on age, gender, diagnosis, duration of hospital stay, treatment, and outcome were collected. Prescriptions were assessed for the use of potentially inappropriate medications in geriatric patients by using American Geriatric Society Beer's criteria (2012) and PRISCUS list (2010). Results: A total of 676 geriatric patients (52.12% females) were admitted in the medicine ward. The average age of geriatric patients was 72.69 years. According to Beer's criteria, at least one inappropriate medicine was prescribed in 590 (87.3%) patients. Metoclopramide (54.3%), alprazolam (9%), diazepam (8%), digoxin > 0.125 mg/day (5%), and diclofenac (3.7%) were the commonly used inappropriate medications. Use of nonsteroidal anti-inflammatory drugs (NSAIDs) in heart and renal failure patients was the commonly identified drug–disease interaction. According to PRISCUS list, at least one inappropriate medication was prescribed in 210 (31.06%) patients. Conclusion: Use of inappropriate medicines is highly prevalent in elderly patients.

    Detection of cardiac injury after blunt chest wall trauma or cardiac surgery is problematic. Previously available biomarkers have been hindered largely by limitations of specifity for myocardial damage. Both cardiac troponin I and T have been evaluated in these patient subgroups. While many questions remain unanswered, it appears that measurement of troponin proteins will facilitate patient care in these difficult situations. PMID:9439875

    Teach-back is a health literacy tool that can be used by orthopaedic nurses to assess their patients' understanding of what has been taught and immediately clarify and review concepts that were misunderstood. Research supports the use of teach-back to engage patients in the learning process, thereby reducing hospital readmissions, and improving self-management, safety, patient satisfaction, and patient outcomes. Nursing journals, however, lack articles that take nurses through the steps of implementing teach-back in their practice. This article describes the four stages of teach-back and takes you step by step through the process of integrating this health literacy tool in your patient education practices. PMID:26575509

    The prevalence of diabetes mellitus (DM) continues to increase each year. However, the efficacy of glucose-lowering therapies remains unsatisfactory. Moreover, the clinical characteristics and manifestations of DM in Chinese patients are different from those in Western patients. Thus, it is imperative to develop an optimal treatment protocol for lowering blood glucose levels in Chinese patients with DM. Sitagliptin has been used in People’s Republic of China, and sitagliptin and metformin combination therapy may not alter their individual pharmacokinetics. To date, several clinical trials undertaken to investigate the efficacy of sitagliptin and metformin combination therapy have revealed that it effectively controlled glycated hemoglobin, fasting plasma glucose, and postprandial plasma glucose levels to a greater extent than sitagliptin or metformin alone. In addition, the combined therapy was well tolerated and induced few side effects, which were largely mild. Furthermore, the combined therapy was easy to administer, and the patients receiving this therapy showed good compliance. Therefore, for Chinese patients with type 2 DM, sitagliptin and metformin combination therapy is preferred. PMID:25709414

    We conducted a chart review on all patients who had received home telemonitoring after an admission for heart failure at the University of Ottawa Heart Institute. During a 5 year period (2005-2009) a total of 645 patients had home monitoring. A total of 594 patients met the inclusion criteria for the study and were divided into two groups: Group 1 (<75 years of age) contained 350 patients and Group 2 (≥75 years of age) contained 244 patients. There was no significant difference between the groups in the mean duration of follow-up by the telemonitoring team: it was 126.5 days in Group 1 and 125.4 days in Group 2 (P = 0.89). There were no significant differences between the groups in the number of times that titration of diuretic medications occurred, the number of times that titration of cardiac medications occurred, the number of interventions for abnormal vital signs or the number of times that patients were called by the telemonitoring staff. Emergency room visits, hospitalizations and the number of deaths were also not different between two groups. Thus in the telemonitoring programme, the pattern of usage by older patients was similar to that of the younger ones. Based on the present study, the elderly do not require more resources nor do they require them for longer. PMID:23390212

    Scleroderma is an autoimmune connective tissue disorder that is characterized by microvascular injury, excessive fibrosis of the skin, and distinctive visceral changes that can involve the lungs, heart, kidneys and gastrointestinal tract. To date, although several drugs have been used to reduce fibrosis in scleroderma, there exists no effective pharmacological treatment. To determine if oral ciprofloxacin reduces the severity of scleroderma, a controlled, double-blind randomized clinical trial, with placebo, was conducted on 32 patients with diffuse and limited scleroderma, who received oral ciprofloxacin (250 mg) or placebo every 12 h. Skin induration and thickness of the patients were clinically evaluated using the modified Rodnan skin score at the beginning and once per month during 6 months of treatment with ciprofloxacin. To monitor progression of the disease, a monthly hematological exam and clinical evaluation was done to explore renal and hepatic function for each patient. Thirty patients completed the study; one from the treatment group was excluded when presenting a skin reaction and another from the placebo group abandoned the study due to an exacerbation of disease. At the sixth month of the study, the ciprofloxacin group of patients showed a diminution in the modified Rodnan skin score (58% vs 18%, P = 0.003), showing no significant alterations in the laboratory assays in either groups of patients. Our results suggest that oral administration of ciprofloxacin for 6 months reduces the severity of symptoms affecting the skin of patients with systemic scleroderma, and does so without important secondary effects.

    Objectives To develop a tool which can easily access the hospital information system (HIS) to facilitate outpatient care and maximize patient satisfaction on his or her hospital visit. Methods Our Center for Informatics developed an outpatient guidance system (OGS) after careful analysis of the list of daily tasks undergone by patients and related work processes. Bluetooth beacons were installed to assist patients, to inform them of points of interest, and to guide them along the proper routes to and within the hospital. Results The OGS conveniently provided patients' clinic schedules, routes to the hospital, and direct costs; all of this information was embedded in the HIS accessed from patients' personal mobile devices or kiosks. Patients were also able to identify their locations within the hospital, receiving proper directions to subsequent task. Since its launch in October 2014, the number of mobile accesses increased from 4,011 to 8,242 per month within a year. Conclusions The substantial growth of interest in and use of our OGS in such a short period indicate that this system has been successfully incorporated into patients' daily activities. We believe that this system will continue to help improve health services and the well-being of those visiting the hospital. PMID:27525158

    Diagnostic bone marrow aspiration, biopsy, and culture are useful procedures in the evaluation of patients with suspected or proven acquired immunodeficiency syndrome (AIDS) who are febrile. In as many as one fourth of these patients, the information provided by the bone marrow examination may establish a diagnosis of a disseminated opportunistic infection when other studies are not informative. We have also discovered a previously unreported association between thrombocytopenia and the presence of bone marrow granulomas in our patients with AIDS and suggest that thrombocytopenia may be a clue to enable the clinician to predict a positive bone marrow result more accurately. The explanation for this apparent association remains to be elucidated. PMID:2733050

    This study analyses the experienced age discrimination of old European citizens and the factors related to this discrimination. Differences in experienced discrimination between old citizens of different European countries are explored. Data from the 2008 ESS survey are used. Old age is defined as being 62 years or older. The survey data come from 28 European countries and 14,364 old-age citizens. Their average age is 72 years. Factor analysis is used to construct the core variable 'experienced discrimination'. The influence of the independent variables on experienced discrimination is analysed using linear regression analysis. About one-quarter of old European citizens sometimes or frequently experience discrimination because of their age. Gender, education, income and belonging to a minority are related to experienced age discrimination. Satisfaction with life and subjective health are strongly associated with experienced age discrimination, as is trust in other people and the seriousness of age discrimination in the country. Large, significant differences in experienced discrimination due to old age exist between European countries. A north-west versus south-east European gradient is found in experienced discrimination due to old age. The socio-cultural context is important in explaining experienced age discrimination in old European citizens. Old-age discrimination is experienced less frequently in countries with social security arrangements. Further research is needed to understand the variation in (old) age discrimination between European countries. Measures recommended include increasing public awareness about the value of ageing for communities and changing public attitudes towards the old in a positive way. PMID:22207825

    Background To study the frequency and pattern of use of complementary and alternative medicine (CAM) in patients with essential hypertension attending a tertiary hypertension clinic. Methods Two hundred and twenty-five consecutive hypertensive patients attending the hypertension clinic of the Lagos University Teaching Hospital over a 3-month period were interviewed. Socio-demographic data, duration of hypertension, clinic attendance, current blood pressure, and compliance to conventional medications was documented. CAM utilization was explored using both structured and open-ended questions. Results There were 90 (40%) male and 135 (60%) female patients with mean age ± SD overall was 55.1 ± 12.4 years. 88 (39.1%) of the respondents used CAM. Herbal products were the most commonly used CAM type. Amongst the CAM users, the most common herbal product used was garlic (69.3%). Others were native herbs (25%), ginger (23.9%), bitter leaf (Vernonia amygdalina) (9.1%), and aloe vera (4.5%). 2.5% used spiritual therapy. There was no difference in the clinical characteristics, socio-economic status, and blood pressure control of CAM users and non-users. Patients who utilized CAM had higher BMI compared with those who did not, but the difference was not statistically significant (mean BMI ± SD of 29.1 ± 5.6 vs 27.1 ± 5.9 kg/m2; P = 0.05). Conclusion A significant proportion of hypertensive patients attending our tertiary facility and receiving conventional treatment also use CAM therapies. Clinicians need to be aware of this practice, understand the rationale for this health-seeking behaviour, proactively enquire about their use, and counsel patients regarding the potential of some of the therapies for adverse reactions and drug interactions.

    Primary brain tumors are associated with significant physical, cognitive and psychosocial changes. Although treatment guidelines recommend offering multidisciplinary rehabilitation and support services to address patients' residual deficits, the extent to which patients access such services is unclear. This study aimed to assess patients' supportive care needs early after diagnosis, and quantify service awareness, referral and utilization. A population-based sample of 40 adults recently diagnosed with primary brain tumors was recruited through the Queensland Cancer Registry, representing 18.9 % of the eligible population of 203 patients. Patients or carer proxies completed surveys of supportive care needs at baseline (approximately 3 months after diagnosis) and 3 months later. Descriptive statistics summarized needs and service utilization, and linear regression identified predictors of service use. Unmet supportive care needs were highest at baseline for all domains, and highest for the physical and psychological needs domains at each time point. At follow-up, participants reported awareness of, referral to, and use of 32 informational, support, health professional or practical services. All or almost all participants were aware of at least one informational (100 %), health professional (100 %), support (97 %) or practical service (94 %). Participants were most commonly aware of speech therapists (97 %), physiotherapists (94 %) and diagnostic information from the internet (88 %). Clinician referrals were most commonly made to physiotherapists (53 %), speech therapists (50 %) and diagnostic information booklets (44 %), and accordingly, participants most commonly used physiotherapists (56 %), diagnostic information booklets (47 %), diagnostic information from the internet (47 %), and speech therapists (43 %). Comparatively low referral to and use of psychosocial services may limit patients' abilities to cope with their condition and the changes they

    Energy, nitrogen absorption, and nitrogen utilization of two commercial elemental diets, Vivonex and Vital, were compared in 10 teenage boys and girls with Crohn's disease. The diets were given in random order as overnight feedings and were the sole source of nutrients for two consecutive periods of 3 weeks each. Urine and stools were collected for 48 h at the end of each 3-week period. Energy absorption was slightly better on Vivonex (p less than 0.05), although 95-100% of energy was absorbed with both formulas. Nitrogen absorption was not different for the two formulas, but nitrogen utilization was significantly better on Vital (28.6 +/- 12.9% versus 9.7 +/- 17.7%, p less than 0.01). This difference may be attributable to the different concentrations of sulfur-containing and aromatic amino acids in the two formulas. PMID:3335991

    Utilization of services is an important indicator for estimating access to healthcare. In Norway, the General Practitioner Scheme, a patient list system, was established in 2001 to enable a stable doctor-patient relationship. Although satisfaction with the system is generally high, people often choose a more accessible but inferior solution for routine care: emergency wards. The aim of the article is to investigate contact patterns in primary health care situations for the total population in urban and remote areas of Norway and for major immigrant groups in Oslo. The primary regression model had a cross-sectional study design analyzing 2,609,107 consultations in representative municipalities across Norway, estimating the probability of choosing the emergency ward in substitution to a general practitioner. In a second regression model comprising 625,590 consultations in Oslo, we calculated this likelihood for immigrants from the 14 largest groups. We noted substantial differences in emergency ward utilization between ethnic Norwegians both in rural and remote areas and among the various immigrant groups residing in Oslo. Oslo utilization of emergency ward services for the whole population declined, and so did this use among all immigrant groups after 2009. Other municipalities, while overwhelmingly ethnically Norwegian, showed diverse patterns including an increase in some and a decrease in others, results which we were unable to explain.

    There are few studies evaluating the cost-effectiveness of self-management interventions for patients with psoriasis. Motivational interviewing (MI) as a telephone follow-up after climate-heliotherapy was effective on several clinical parameters, but its cost-effectiveness is unknown. A cost-utility analysis was conducted alongside a randomized controlled trial (RCT) comparing MI with usual care. A total of 169 Norwegian patients were included. A within-trial analysis compared the costs and quality-adjusted life years (QALYs). Utilities were measured with the 15D instrument, supplemented with Dermatological Life Quality Index (DLQI). A time-integrated summary score defined the clinical effects. QALYs were adjusted for baseline differences. MI provided equivalent quality of life and utility (15D: -0.0022 QALYs (95% Cl -0.02, 0.01), p = 0.77, and DLQI: -0.62 QALYs (95%CI -0.65, 0.41), p = 0.24, at lower costs €-1103 (-2293, 87), p = 0.058, compared with treatment-as-usual. The MI intervention was thus cost-effective. This result was more evident when using the DLQI as outcome measure compared with 15D. PMID:26714522

    OBJECTIVES The objectives of this evaluation of medication use were to characterize the use of intravenous acetaminophen at our institution and to determine if acetaminophen was prescribed at age-appropriate dosages per institutional guidelines, as well as to evaluate compliance with restrictions for use. Total acquisition costs associated with intravenous acetaminophen usage is described as well. METHODS This retrospective study evaluated the use of acetaminophen in pediatric patients younger than 18 years of age, admitted to a tertiary care hospital, who received at least 1 dose of intravenous acet-aminophen between August 1, 2011, and January 31, 2012. RESULTS A total of 52 doses of intravenous acetaminophen were administered to 31 patients during the 6-month study period. Most patients were admitted to the otorhinolaryngology service (55%), and the majority of doses were administered either in the operating room (46%) or in the intensive care unit (46%). Nineteen doses (37%) of intravenous acetaminophen were administered to patients who did not meet institutional guidelines' eligibility criteria. Three patients received single doses of intravenous acetaminophen that were greater than the dose recommended for their age. One patient during the study period received more than the recommended 24-hour maximum cumulative dose for acetaminophen. Total acquisition cost of intravenous acetaminophen therapy over the 6-month study period was $530.40. CONCLUSIONS Intravenous acetaminophen was used most frequently among pediatric patients admitted to the otorhinolaryngology service during the perioperative period. Nineteen doses (37%) were administered to patients who did not meet the institutional guidelines' eligibility criteria. Our data support reinforcing the availability of institutional guidelines to promote cost-effective use of intravenous acetaminophen while minimizing the prescription of inappropriate doses.

    Cutaneous melanoma is one of the highest incident-rate cancers with increasing prevalence in Western societies. Despite the advent of new approved therapeutics, the 5-year overall survival rate of stage IV melanoma patients remains below 15%. Current treatments for late stage disease have shown higher efficacy when treated at a lower disease burden. Thus, blood-based biomarkers capable of detecting melanoma prior to clinically evident distant metastasis, will improve the treatment and outcomes for melanoma patients. To that end, effective treatment of melanoma necessitates identification of patients at risk for developing distant metastases. Furthermore, employing blood biomarkers that monitor cancer progression over the course of treatment is a promising solution to post-treatment drug resistance often developed in melanoma patients. Non-invasive blood biomarker assays allow for regular dynamic monitoring of disease. "Liquid Biopsy" of blood, which exploits circulating tumor cells (CTCs), cell-free circulating tumor DNA (ctDNA) and cell-free circulating microRNA (cmiRNA), has been shown to detect prognostic factors for relapse in AJCC stage III and stage IV melanoma patients. Moreover, molecular characterization of CTC and analysis of various forms of ctDNA present promising potential in development of individualized therapy for melanoma patients. New approaches such as massive parallel sequencing (MPS) provide a comprehensive view of the disease progression, allowing for the selection of therapeutic options for individual patients. With advancements of improving molecular assays, liquid biopsy analysis as a powerful, routine clinical assay for melanoma patients, is highly promising prospective. PMID:26778792

    The prognostic value of T-wave alternans (TWA) during the night time in patients with Brugada syndrome (Br-S) remains unknown. We assessed TWA for risk stratification using 24-h multichannel Holter electrocardiogram (24-M-ECG) in Br-S. We enrolled 129 patients with Br-S [grouped according to histories of ventricular fibrillation (VF), n = 16; syncope, n = 10; or no symptoms (asymptomatic), n = 103] and 11 controls. Precordial electrodes were attached to the third (3L-V1, 3L-V2) and fourth (4L-V1, 4L-V2 and 4L-V5) intercostal spaces. We measured the values of maximum TWA (max-TWA) during the night time (12 a.m.-6 a.m.) and the day time (12 p.m.-6 p.m.) and calculated parameters of heart rate variability. Compared to the asymptomatic and control groups, the VF and syncope groups showed significantly greater 3L-V2 max-TWA during the night time. The cutoff value for the 3L-V2 max-TWA during the night time was determined as 20 µV (sensitivity 94 % and specificity 48 %; p = 0.01). Multivariate analysis revealed that 3L-V2 max-TWA during the night time ≥20 µV and previous VF episodes were independent predictors of future VF episodes. During a mean follow-up period of 68 ± 37 months, 16 patients experienced VF episodes. The incidence of VF episodes was the highest during the night time (p < 0.001). The 3L-V2 max-TWA during the night time may be a useful predictor for VF episodes in patients with Br-S. PMID:25989739

    The goal of levo-thyroxine (L-T4) administration in differentiated thyroid cancer (DTC) is to suppress thyroid stimulating hormone (TSH) levels. The tolerability and efficacy of a new formulation of liquid L-T4 vs. the previous tablet formulation was evaluated in a cohort of 59 patients with cured DTC. The correlation between breakfast modality and therapy was also monitored. Hormonal and clinical evaluations were performed before and 70 days after patients were switched from tablet to liquid L-T4 formulation, without changes in daily dose. Breakfast habits were evaluated. The interval between L-T4 therapy and breakfast was recorded. Patient approval of L-T4 formulations was evaluated. 8% of patients dropped out owing to adverse events. The modality of L-T4 administration proved adequate under tablet and liquid formulation in 64% and 68% of patients who fully complied with the protocol. While significantly more patients found the tablet formulation more agreeable, at the end of the protocol subjective symptoms had diminished significantly and 73% requested to remain on the liquid formulation. No change in TSH, thyroid hormones or thyroglobulin was noted during the study. A balanced breakfast containing less than 4 g of alimentary fibre did not interfere with L-T4 therapy. Liquid L-T4 seems to be a valid alternative formulation in DTC patients, its initial dislike being outweighed by a significant reduction in subjective symptoms. Both tablet and liquid L-T4 therapy require monitoring over time. A continental breakfast containing less than 4 g of alimentary fibres seems to favour the absorption of L-T4, whether in tablet or liquid formulation. PMID:25020105

    Chronic heart failure (CHF) remains a leading cause of cardiovascular death worldwide. Current risk models allow better prognosis, however further tools for assessing risk are needed. Thus, this study was aimed to evaluate whether biomarker risk prediction score is powerful tool for risk assessment of three-year fatal and non-fatal cardiovascular events in CHF patients. Methods: A prospective study on the incidence of fatal and non-fatal cardiovascular events, as well as the frequency of occurrence of death from any cause in a cohort of 388 patients with CHF during 3 years of observation was performed. Circulating levels of NT-pro brain natriuretic peptide (NT-pro-BNP), galectin-3, high-sensitivity C-reactive protein (hs-CRP), osteoprotegerin and its soluble receptor sRANKL, osteopontin, osteonectin, adiponectin, endothelial apoptotic microparticles (EMPs) and mononuclear progenitor cells (MPCs) were measured at baseline. Results: Median follow-up of patients included in the study was 2.76 years. There were 285 cardiovascular events determined, including 43 deaths and 242 readmissions. Independent predictors of clinical outcomes in patients with CHF were NT-pro-BNP, galectin-3, hs-CRP, osteoprotegerin, CD31+/annexin V+ EMPs and EMPs/CD14+CD309+ MPCs ratio. Index of cardiovascular risk was calculated by mathematical summation of all ranks of independent predictors, which occurred in the patients included in the study. The findings showed that the average value of the index of cardiovascular risk in patients with CHF was 3.17 points (95% CI = 1.65-5.10 points). Kaplan-Meier analysis showed that patients with CHF and the magnitude of the risk of less than 4 units have an advantage in survival when compared with patients for whom obtained higher values of ranks cardiovascular risk score. Conclusion: Biomarker risk score for cumulative cardiovascular events, constructed by measurement of circulating NT-pro-BNP, galectin-3, hs-CRP, osteoprotegerin, CD31+/annexin V+ EMPs

    Study of diagnostic practice is necessary to optimize neurologists' clinical performance and ensure patient safety. To our knowledge, this report is the first set of systematic observations of diagnostic practices of community neurologists in their clinics. The study consisted of six 2-week periods of in situ observations and interviews of 6 experienced community neurologists in Northern California. We describe 3 core domains of diagnosis: 1) clinical (C), 2) laboratory and electrodiagnostics (L), and 3) neuroimaging (N). Neurologists were uniform in their practices across these domains except within the clinical domain, where the physical examination varied considerably among clinicians. All neurologists coordinated findings from the 3 domains to arrive at a final diagnosis. This practice of coordination varied across common disease categories (e.g., meningitis vs dementia). To codify this variance, we developed a provisional model of diagnostic practice derived from the data consisting of a 3-point coordinate shorthand (Cx Lx Nx) and a graphic. This model shows the relative emphasis of each of the 3 core domains for 9 common diagnoses (e.g., stroke is C4 L1 N4 with "4" as the highest priority per domain). The data reveal a heavy emphasis on the clinical domain for most diagnoses. The model may be useful for trainees to learn how to allocate time to make a diagnosis. It may help educators build curricula and evaluation systems that emphasize concrete activities of diagnostic practice. Lastly, our model provides a structure to teach resource utilization and cost containment relating to neurologic diagnoses. PMID:24049130

    Down syndrome (DS) is the most common cause of mental retardation. The frequency of DS patients is about 1:800 and is mainly because of the presence of extra copy of chromosome number 21. Dermatoglyphic has been well established as a diagnostic aid in number of diseases having hereditary basis. Dermatoglyphic data was obtained by the use of ink and prints on a paper, from 15 cytogenetically confirmed patients of Down syndrome attending to the genetic clinic at BPKIHS. The data were correlated and compared with equal number of controls. Dermatoglyphic prints were used to evaluate the variation in the fingerprint patterns, the presence of simian crease and the difference in 'atd' 'dat' and 'adt' angles between the control and the DS patients. The results showed that both the 'atd' and 'adt' angles differed significantly from the control group. The dactylography study revealed higher incidence of loops and lower incidence of whorls in the DS patients as compared with the controls. This method is non-invasive and cost effective. The observed changes in the 'atd' and 'adt' angles plus the fingerprint patterns in the dermatoglyphic study proved that this simple technique could be a valuable tool for selecting patients of DS for cytogenetics analysis.

    Purpose: Arch aneurysm combined with insufficient Zone 1 length remains challenging. While a chimney stentgraft with supra-aortic bypass is a recognized solution for arch aneurysm, no definite strategy has been established yet. The aim of this study was to investigate efficacy of chimney stentgraft for patients with zone 1 of insufficient length. Methods: Between 2011 and 2013, 10 consecutive patients with aortic arch aneurysm who were treated with a chimney stentgraft were retrospectively reviewed. The minimum length of zone 1 and length of landing zone inside zone 0 were measured on pre-/post-operative 3D-CT. Results: Neither in-hospital mortality nor postoperative stroke was encountered. The minimum median length of zone 1 (zone 2 for bovine aortic arch of two patients) on preoperative 3D-CT was 10.1 mm [range: 3.9–15.3]. On postoperative 3D-CT, the median proximal landing length on a major curvature proximal to brachio-cephalic artery was 37.5 [range: 20.9–63.9] mm. Type Ia endoleak was observed in two patients with a landing length along the major curvature of less than 30 mm. Conclusion: For patients with insufficient length of zone 1, aneurysm exclusion could be achieved with a chimney stentgraft ensuring sufficient length (>30 mm) of the landing zone inside the ascending aorta along major curvature.

    Amyotrophic Lateral Sclerosis(ALS) patients are unable to successfully communicate their desires, although their mentality is normal, and so, the necessity of Communication Aids(CA) for ALS patients is realized. Therefore, the authors are focused on Event-Related Potential(ERP) which is elicited primarily for the target by visual and auditory stimuli. P200, N200 and P300 are components of ERP. These are potentials that are elicited when the subject focuses attention on stimuli that appears infrequently. ALS patient participated in two experiments. In the first experiment, a target word out of five words on a computer display was specified. The five words were linked to an each electric appliance, allowing the ALS patient to switch on a target appliance by ERP. In the second experiment, a target word in a 5×5 matrix was specified by measure of ERP. The rows and columns of the matrix were reversed randomly. The word on a crossing point of rows and columns including the target word, was specified as the target word. The rate of correct judgment in the first and second experiments were 100% in N200 and 96% in P200. For practical use of this system, it is very important to determine suitable communication algorithms for each patient by performing these experiments evaluating the results.

    Dental hygiene educators must determine which educational practices best promote critical thinking, a quality necessary to translate knowledge into sound clinical decision making. The aim of this small pilot study was to determine whether virtual patient simulation had an effect on the critical thinking of dental hygiene students. A pretest-posttest design using the Health Science Reasoning Test was used to evaluate the critical thinking skills of senior dental hygiene students at The University of Texas School of Dentistry at Houston Dental Hygiene Program before and after their experience with computer-based patient simulation cases. Additional survey questions sought to identify the students' perceptions of whether the experience had helped develop their critical thinking skills and improved their ability to provide competent patient care. A convenience sample of 31 senior dental hygiene students completed both the pretest and posttest (81.5% of total students in that class); 30 senior dental hygiene students completed the survey on perceptions of the simulation (78.9% response rate). Although the results did not show a significant increase in mean scores, the students reported feeling that the use of virtual patients was an effective teaching method to promote critical thinking, problem-solving, and confidence in the clinical realm. The results of this pilot study may have implications to support the use of virtual patient simulations in dental hygiene education. Future research could include a larger controlled study to validate findings from this study. PMID:26329033

    Background The clinical benefit of helicopter transport over ground transportation for interfacility transport is unproven. We sought to determine actual practice patterns, utilization, and outcomes of patients undergoing interfacility transport for neurosurgical conditions. Methodology/Principal Findings We retrospectively examined all interfacility helicopter transfers to a single trauma center during 2008. We restricted our analysis to those transfers leading either to admission to the neurosurgical service or to formal consultation upon arrival. Major exclusion criteria included transport from the scene, death during transport, and transport to any area of the hospital other than the emergency department. The primary outcome was time interval to invasive intervention. Secondary outcomes were estimated ground transportation times from the referring hospital, admitting disposition, and discharge disposition. Of 526 candidate interfacility helicopter transfers to our emergency department in 2008, we identified 167 meeting study criteria. Seventy-five (45%) of these patients underwent neurosurgical intervention. The median time to neurosurgical intervention ranged from 1.0 to 117.8 hours, varying depending on the diagnosis. For 101 (60%) of the patients, estimated driving time from the referring institution was less than one hour. Four patients (2%) expired in the emergency department, and 34 patients (20%) were admitted to a non-ICU setting. Six patients were discharged home within 24 hours. For those admitted, in-hospital mortality was 28%. Conclusions/Significance Many patients undergoing interfacility transfer for neurosurgical evaluation are inappropriately triaged to helicopter transport, as evidenced by actual times to intervention at the accepting institution and estimated ground transportation times from the referring institution. In a time when there is growing interest in health care cost containment, practitioners must exercise discretion in the

    Atrial fibrillation is the most common of the cardiac arrhythmias and is associated with high risk of stroke and systemic thromboembolism. Prevention of these complications is therefore a major component of clinical management in patients with this rhythm disorder. The choice of antithrombotic therapy in any given patient depends on his or her risk profile and needs to be carefully balanced against the risk of bleeding. In this review we discuss the pathophysiology of thrombogenesis in atrial fibrillation, risk factors for systemic thromboembolism in atrial fibrillation, patient risk stratification modules both for systemic thromboembolism and the risk of bleeding, current antithrombotic therapy strategies, clinicoepidemiological evidence that led to their evolvement, the challenges that plague them, recent developments in the field and how they could possibly affect our future clinical decision making.

    Transoesophageal echocardiography (TEE) has earned an important role in the evaluation of patients with cardiovascular diseases. We report our TEE experience in 901 patients who had suboptimal transthoracic echocardiographic studies performed between September 1989 and June 1993. The patient-population consisted of 459 females and 442 males, with an ethnic distribution of Chinese 76.5%, Malays 12.7%, Indians 8.5% and Others 2.3%. The mean age was 48 years. The main indications for TEE were: cardiac source of embolism (27.5%); native valve pathology (19.1%); atrial septal abnormality (9.7%); infective endocarditis (8.3%); intracardiac masses (7.0%); prosthetic valve dysfunction (6.3%); congenital heart diseases (4.6%); aortic diseases (3.4%) and miscellaneous (14.1%). The majority of the studies were done on in- and out-patients, with only 1.2% performed in the intensive care area and 1% intraoperatively. 82.6% of TEE intubation were accomplished within one minute and most of the TEE studies were completed within twenty minutes. There were ten failures (1.2%). Major complications occurred in 5 patients (0.6%) but there was no mortality. 90.5% of the studies were considered by the operators as additionally-informative or useful for clinical decision making. In a subgroup analysis, 90.6% of the patients who had undergone TEE indicated their willingness for repeat studies if required and TEE was able to increase the sensitivity of detecting a potential cardioembolic source from 10.3% to 29.5%. In conclusion, with increasing experience, TEE can be performed expeditiously and safely, with good acceptability by our local population. TEE provides useful or additional information that supplements standard transthoracic echocardiography in a wide-ranging spectrum of cardiac conditions. PMID:8882528

    Type 2 diabetes mellitus (T2DM) is a major risk factor for the development of cardiovascular disease (CVD). Due to the ever increasing incidence of both T2DM and CVD and coexistence of these disorders, numerous agents have been developed over the years to target complications. We focus on the efficacy and safety perspective of a long-acting formulation of the glucagon-like peptide-1 analog exenatide. Our review focuses on the various landmark trials, efficacy, safety profile, and patient perspectives of weekly exenatide that delineates its current and future role in the treatment of patients with T2DM and CVD.

    Diagnosis of infections in cancer patients is usually problematic since differentiating between infection and fever of unknown origin is often a considerable clinical challenge. In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detecting severe infections, mainly bloodstream infection, in patients with hematological cancers. In all clinical situations, the elevated level of PCT should be carefully analyzed, always with a thorough physical examination and an appropriate microbiological assessment. PMID:26858528

    Seizure localization includes neuroimaging like electroencephalogram, and magnetic resonance imaging (MRI) with limited ability to characterize the epileptogenic network. Temporal clustering analysis (TCA) characterizes epileptogenic network congruent with interictal epileptiform discharges by clustering together voxels with transient signals. We generated epileptogenic areas for 12 of 13 epilepsy patients with TCA, congruent with different areas of seizure onset. Resting functional MRI (fMRI) scans are noninvasive, and can be acquired quickly, in patients with different levels of severity and function. Analyzing resting fMRI data using TCA is quick and can complement clinical methods to characterize the epileptogenic network. PMID:27362339

    The HeartWare ventricular assist device (HVAD) is an implantable continuous-flow centrifugal pump that has allowed the development of sternal-sparing techniques, with the use of alternative outflow strategies. We compared early outcomes for patients bridged with the conventional versus alternative outflow graft strategy. From January 2013 to October 2014, 89 patients with HVAD implantation were identified. Survival was analyzed with Kaplan-Meier methods, and a log-rank test was used to compare outcomes between groups. Thirty patients (34%) had ≥1 previous sternotomy before HVAD implantation. Eight patients (27%) were approached using an alternative outflow graft technique with outflow graft connection to the descending aorta (n = 4, 50%) or left subclavian artery (n = 4, 50%), whereas 22 (73%) were implanted via a conventional sternotomy approach with the outflow graft to the ascending aorta. Preoperative characteristics (age, Interagency Registry for Mechanically Assisted Circulatory Support [INTERMACS], and Lietz-Miller score) were comparable between groups (all p > 0.05). Median follow-up was 4.7 (2.8-9.3) months of support. Outcomes were comparable between conventional and alternative outflow groups; survival at 6 months was 74% for the conventional group and 83% in the alternative outflow group. An alternative outflow graft strategy can be utilized to support bridged patients with a history of prior sternotomy. PMID:27111737

    The objective of this study was to utilize the electronic medical record system to identify frequent lower acuity patients presenting to the Pediatric Emergency Department and to evaluate their impact on Pediatric Emergency Department overcrowding and resource utilization. The electronic medical records (EMR) of two pediatric emergency centers were reviewed from August 2002 to November 2004. Pediatric Emergency Department encounters that met any of the following criteria were classified as Visits Necessitating Pediatric Emergency Department care (VNEC): Disposition of admission, transfer or deceased; Intravenous fluids (IVF) or medications (excluding single antipyretic or antihistamine); Radiology or laboratory tests (excluding Rapid Strep); Fractures, dislocations, and febrile seizures. All other visits were classified as non-VNEC. ICD-9 (International Classification of Diseases, Ninth Revision) codes from the Pediatric Emergency Department encounters were defined as representing chronic or non-chronic conditions. Patients were then evaluated for utilization patterns, frequency of Emergency Department (ED) visits, chronic illness, and VNEC status. There were 153,390 patients identified, representing 255,496 visits (1.7 visits/patient, range 1-49). Overall, 189,998 visits (74%) required defined ED services and were categorized as VNEC, with the remaining 65,498 visits (26%) categorized as non-VNEC. With increasing visits, a steady decline in those requiring ED services was observed, with a plateau by visit six (VNEC 77% @ one visit, 64% @ six visits, p < 0.001). There were 141,765 patients seen fewer than four times, representing 92% of the patients and 74% of all visits (1.3 visits/patient, 225 visits/day). In contrast, 2664 patients disproportionately utilized the ED more than six times (maximum 49), representing 1.7% of patients and 9.8% of visits (9.4 visit/patient, 30 visits/day, p < 0.001).

    To evaluate pattern of using of three antifungal drugs: fluconazole, amphotericin B and voriconazole, at the hematology–oncology and bone marrow transplant wards of one large teaching hospital. In a prospective cross-sectional study, we evaluated the appropriateness of using antifungal drugs in patients, using Infectious Disease Society of America (IDSA) and National Comprehensive Cancer Network (NCCN) guidelines. All the data were recorded daily by a pharmacist in a form designed by a clinical pharmacist and infectious diseases specialist, for antifungals usage, administration, and monitoring. During the study, 116 patients were enrolled. Indications of prescribing amphotericin B, fluconazole, and voriconazole were appropriate according to guidelines in 83.4%, 80.6%, and 76.9% respectively. The duration of treatments were appropriate according to guidelines in 75%, 64.5%, and 71.1% respectively. The dose of voriconazole was appropriate according to guidelines in 46.2% of patients. None of the patients received salt loading before administration of amphotericin B. The most considerable problems with the mentioned antifungals were about the indications and duration of treatment. In addition, prehydration for amphotericin B and dosage of voriconazole were not completely compatible with the mentioned guidelines. A suitable combination of controlling the use of antifungals and educational programs could be essential for improving the general process of using antifungal drugs at our hospital. PMID:26064070

Botanical herbs (including Gymnema sylvestre) and nutrients (including alpha lipoic acid and chromium) were used alongside metformin to help improve insulin sensitization; however, the greatest emphasis of treatment for this patient centered on a low-carbohydrate, whole-foods diet and regular exercise that shifted the focus to the patient's role in controlling their disease. Research on DM2 often focuses on improving drug efficacy while diet and lifestyle are generally overlooked as both a preventive and curative tool. During the 7 months of treatment, the patient's hemoglobin A1c and fasting glucose significantly decreased to within normal ranges and both cholesterol and liver enzyme markers normalized. A significant body of evidence already exists advocating for disease management using various diets, including Mediterranean, low-carb, and low-fat vegan diets; however, no clear dietary standards have been established.

    In the present study, we investigated the clinical effects of image-guided iodine-125 ((125)I) seed on unresectable pancreatic cancer. Twenty-five patients with unresectable pancreatic cancer were enrolled in this study, including 13 patients with seed implantation and 12 patients as control. The survival status, clinical benefits, objective curative effects, and relevant tumor markers were analyzed to assess the feasibility and safety of interstitial (125)I seed implantation. We found that the clinical benefit rate of the seed implantation group is 92.3 % (12/13), compared with 41.7 % (5/12) in the control, and the difference was statistically significant (p < 0.01). Compared with control, patients with seed implantation had significantly shorter operative time, less bleeding, higher albumin, shorter periods to bowel movement, and normal diet as well as lower risk of complications (p < 0.001). The differences of objective curative effects adverse effects, complications, and median survival between these two groups were not significant statistically (p > 0.05). In conclusion, (125)I seed implantation provides a safe and effective method to inhibit the tumor development, relieve pain, and improve quality of life for unresectable pancreatic cancer. These findings need to be validated by conducting further studies with larger cohorts. PMID:26353858

    This study describes how melanoma patients used the Internet as a melanoma information source and how it impacted their clinical encounter and treatment decision. From 2010 to 2013, melanoma patients were invited to complete a 23-question paper survey with open- and close-ended questions. Thirty-one of the 62 patients approached completed the survey. The majority (90 %) of respondents used the Internet as a melanoma information source. Most (90 %) had used the search engine Google. The most commonly searched topics were melanoma treatment (96 %), screening (64 %), and prevention (64 %). While most respondents (85 %) found the Internet was a useful melanoma information source, over half (54 %) found melanoma websites at least somewhat difficult to understand. Many (78 %) believed it increased their understanding of their diagnosis, 71 % thought it influenced their treatment decision, and 59 % felt it impacted their specialist consultation. This study informs health care professionals that many melanoma patients search the Internet for information regarding their diagnosis and that it may impact their disease understanding and treatment decisions.

    Postprandial hypotension, defined as a fall in systolic blood pressure (SBP) of 20 mmHg or greater within 2 hours after a meal, is a risk factor for stroke, coronary events and mortality. The clinical suspicion is typically raised by episodes of postprandial syncope or falls, whereas asymptomatic postprandial hypotension is mostly neglected. The magnitude of the postprandial fall in SBP, as detected by 24-hour recording in apparently healthy middle-aged to elderly subjects, was proportional to the severity of the silent cerebrovascular damage. Postprandial hypotension can also be detected by self-measured blood pressure before and within 2 hours after meals using automatic devices. The review highlights the value of home blood pressure monitoring (HBPM) as a screening test for asymptomatic postprandial hypotension in hypertensive patients. Using a HBPM protocol that included duplicated blood pressure measurements before and after three consecutive lunches, we detected unsuspected postprandial hypotension in 27.4% of the 230 hypertensive patients screened. The prevalence of postprandial hypotension was 13.2% in controlled and 42.2% in uncontrolled hypertensive patients (p < 0.001), raising the dilemma of further lowering blood pressure in the setting of postprandial hypotension. The inclusion of preprandial and postprandial measurements in the protocol of HBPM is useful to identify hypertensive patients with postprandial hypotension and may guide adjustments in antihypertensive treatment according to postprandial blood pressure.

    Background Although expected to act as gate-keeping primary care providers, as community health service (CHS) facilities are severely under-utilized; Chinese people in both rural and urban areas used predominantly higher-tier facilities for primary care purpose, with significant financial and outcome consequences. This study intends to explore the determinants of initial utilization of CHS among patients with major non-communicable chronic diseases (NCDs) in order to understand the care-seeking behavior among urban and rural residents in South China. Methods A multi-stage cluster random sampling methodology was adopted to create a sample of 19,466 adults with NCDs from 7,970 urban households and 32,035 adults with NCDs from 3,860 rural households in Guangdong, China. Interviews and physical examinations were conducted in 2010 to collect data on patient characteristics, medical conditions, and awareness and utilization of healthcare. Descriptive analysis and logistic regression analysis were performed to study utilization patterns and the factors associated with the patterns. Results Prevalence of major NCDs in urban areas was significantly higher than that in rural areas (12.55% vs. 8.70%; p<0.001). Second-tier district hospitals were most preferred for initial consultation (46.05% in rural areas vs. 45.32% in urban areas; p<0.001), followed by tertiary general or specialized hospitals (28.39% in rural areas vs. 33.89% in urban areas; p<0.001). The proportion of patients who had initial use of CHS was relatively low (25.56% in rural areas vs. 20.79% in urban areas; p<0.001). Awareness of self-care and the presence of medical insurance were leading factors associated with first contact of CHS facilities in both urban and rural areas. Conclusion The study suggests that CHS facilities are not often used as the first contact for patients in both rural and urban areas in south China. Much effect must be made to enhance the gatekeeper system and improve medical insurance

    Background A need exists to expand the characterization of tetrahydrobiopterin (BH4) responsiveness in patients with phenylketonuria (PKU), beyond simply evaluating change in blood phenylalanine concentrations. The clinical interpretation of BH4 responsiveness should be evaluated within the context of phenylalanine hydroxylase (PAH) genotype. Aim This investigation seeks to use a modified version of a previously developed PAH genotype severity tool, the assigned value (AV) sum, to assess the molecular basis of responsiveness in a clinical cohort and to explore the tool’s ability to differentiate BH4 responsive groups. Methods BH4 response was previously clinically classified in 58 patients with PKU, with three response groups emerging: definitive responders, provisional responders, and non-responders. Provisional responders represented a clinically ambiguous group, with an initial decrease in plasma phenylalanine concentrations, but limited ability to improve dietary phenylalanine tolerance. In this retrospective analysis, mutations in the PAH gene were identified in each patient. PAH genotype was characterized through the AV sum approach, in which each mutation is given an AV of 1, 2, 4, or 8; the sum of both mutations’ AV corresponds to genotype severity, with a lower number representing a more severe phenotype. An AV sum cutoff of 2 (indicative of the most severe genotypes) was used to dichotomize patients and predict BH4 responsiveness. Provisional responders were classified with the definitive responders then the non-responders to see with which group they best aligned. Results In 17/19 definitive responders, at least one mutation was mild or moderate in severity (AV sum>2). In contrast, 7/9 provisional responders carried two severe or null mutations (AV sum=2), suggesting little molecular basis for responsiveness. Non-responders represent a heterogeneous group with 15/25 patients carrying two severe mutations (AV sum=2), 5/25 patients carrying one

    AIM To estimate the levels of serum cytokines in chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC) patients in order to evaluate their usefulness as possible biomarkers. METHODS The study included 167 Caucasian patients: 74 with PDAC (28 men and 42 women, aged 30-88 years), 78 with CP (50 men and 21 women, aged 20-79 years) and 15 age-matched healthy controls hospitalized in the Department of Digestive Tract Diseases, Medical University of Lodz, Poland between 2006 and 2013. Serum MCP-1, transforming growth factor (TGF)-β1, HA and s-Fr were measured in patients with CP (n = 78), PDAC (n = 74) and healthy controls (n = 15) using ELISA (Corgenix United Kingdom Ltd R and D Systems). The severity of CP was assessed according to the Cambridge classification. RESULTS Both patients with CP and PDAC had a significantly higher mean TGF-β1 serum level (1066 ± 582 and 888 ± 356 vs 264 ± 93, P < 0.0001), mean s-Fr (2.42 ± 1.385 and 2.41 ± 1.275 vs 0.6 ± 0.370, P < 0.0001) and mean HA (199 ± 254 and 270 ± 358 vs 40 ± 26, P < 0.0001) compared to controls. There was no difference in mean MCP-1 between all the groups. There were no significant differences in any cytokine levels between the PC and PDAC groups. No significant differences between serum cytokines depending on age, gender or smoking status were found in CP patients. Mean s-Fr concentration was significantly higher in CP, lasting longer than 5 years compared to those with a shorter disease clinical course (2.639 ± 1.125 vs 1.870 ± 0.970, P < 0.03). There was no correlation between tumor size, localization or TNM classification and serum TGF-β1, MCP-1, s-Fr and HA levels in patients with PDAC. No significant differences between cytokines depending on diabetes presence in CP were found. Nevertheless, mean serum TGF-β1 concentration in PDAC patients was higher in those with diabetes compared to the remaining group (986 vs 839, P = 0.043). CONCLUSION Serum TGF-β1, s-Fr and HA may be

    Objective 1) To identify English Language published patient-reported upper extremity outcome measures used in breast cancer research and 2) To examine construct validity and responsiveness in patient-reported upper extremity outcome measures used in breast cancer research. Data Sources PubMed, CINAHL and ProQuest MEDLINE® databases were searched up to February 5, 2013. Study Selection Studies were included if a patient-reported upper extremity outcome measure was administered, the participants were diagnosed with breast cancer, and published in English. Data Extraction Eight hundred and sixty-five articles were screened. Fifty-nine full text articles were assessed for eligibility. A total of 46 articles met the initial eligibility criteria for aim 1. Eleven of these articles reported mean and standard deviations for the outcome scores, and included a comparison group analysis for aim 2. Data Synthesis Construct validity was evaluated by calculating effect sizes for known group differences in 6 studies using the Disabilities of Arm, Shoulder and Hand (DASH), Penn Shoulder Score, Shoulder Disability Questionnaire-Dutch, and 10 Questions by Wingate (Wingate). Responsiveness was analyzed comparing a treatment and control group by calculating the coefficient of responsiveness in 5 studies for the DASH and Wingate. Conclusions Eight different patient-reported upper extremity outcome measures have been reported in the peer-review literature for women with breast cancer, some (n=3) were specifically developed for breast cancer survivors and others that were not (n=5). Based on the current evidence we recommend administering the DASH to assess patient-reported upper extremity function in breast cancer survivors because the DASH had most consistently large effects sizes for construct validity and responsiveness. Future large studies are needed for more definitive recommendations. PMID:23932969

    Dynamic analysis techniques may uncover abnormalities in heart rate (HR) behavior that are not easily detectable with conventional statistical measures. However, the applicability of these new methods for detecting possible abnormalities in HR behavior in various cardiovascular disorders is not well established. Conventional measures of HR variability were compared with short-term (< or = 11 beats, alpha1) and long-term (> 11 beats, alpha2) fractal correlation properties and with approximate entropy of RR interval data in 38 patients with stable angina pectoris without previous myocardial infarction or cardiac medication at the time of the study and 38 age-matched healthy controls. The short- and long-term fractal scaling exponents (alpha1, alpha2) were significantly higher in the coronary patients than in the healthy controls (1.34 +/- 0.15 vs 1.11 +/- 0.12 [p <0.001] and 1.10 +/- 0.08 vs 1.04 +/- 0.06 [p <0.01], respectively), and they also had lower approximate entropy (p <0.05), standard deviation of all RR intervals (p <0.01), and high-frequency spectral component of HR variability (p <0.05). The short-term fractal scaling exponent performed better than other heart rate variability parameters in differentiating patients with coronary artery disease from healthy subjects, but it was not related to the clinical or angiographic severity of coronary artery disease or any single nonspectral or spectral measure of HR variability in this retrospective study. Patients with stable angina pectoris have altered fractal properties and reduced complexity in their RR interval dynamics relative to age-matched healthy subjects. Dynamic analysis may complement traditional analyses in detecting altered HR behavior in patients with stable angina pectoris.

    The field of pain medicine that once began as a supportive and compassionate care, adding value to the management of acute and chronic ailments, has now transformed into a vital and essential specialty with structured training programs and service units with professionals dedicating their careers to it. The expansion of understanding of the direct relationship of pain relief to the quality of life, uncovering of neuronal pathways, and technological advances in imaging as well as in interventional techniques have all contributed to this phenomenal growth. However, there is a growing concern whether the training programs and the specialized practitioners are gradually limiting their skilled inputs primarily within the sensory realm of the pain experience with sophisticated interventional techniques and relegating its subjective and emotional dimensions to perfunctory realms within the schema of service provision. While the specialty is still young, if we can understand the inherent aspect of these dimensions within the pain experience and acknowledge the gaps in service provision, it may be possible to champion development of truly comprehensive pain relief programs that responds effectively and ethically to a patient's felt needs. This article attempts to position the subjectivity of pain experience in context and surface the need to design complete systems of pain relief services inclusive of this dimension. It presents authors' review of literature on perspectives of 'unpleasant subjective emotional experiencing of the pain" to elucidate possible clinical implications based on the evidences presented on neuro-biology and neuro-psychology of the pain experience; the aim being to inspire systems of care where this dimension is sufficiently evaluated and managed.

    Emergency hospital utilization rates for asthma remain high despite advances in asthma controller medications and the presence of widely accepted asthma treatment guidelines. To explore this phenomenon, we analyzed administrative data to determine characteristics of patients seen in the emergency department (ED) for asthma. Complete pharmacy and diagnostic coding records were obtained from consecutive adults (aged 19-56 years) treated for asthma in the ED of a closed-network health maintenance organization between April and July of 2002. Subjects were stratified into asthma severity categories (persistent or non-persistent) based on the National Committee for Quality Assurance 2006 Health Plan and Employer Data and Information Set (HEDIS) criteria for persistent asthma. Eighty-one unique patients made a total of 89 ED visits for asthma during the study period. Of the 89 total ED visits for asthma, 44 (49%) occurred in patients that did not meet HEDIS criteria for persistent asthma. Of the 81 unique patients making asthma-related ED visits, 41 (51%) did not meet HEDIS criteria for persistent asthma. Over one-half (51%) of this nonpersistent population were not given either asthma reliever or asthma controller medications during the 12-month period before their index ED visit. Over the 24-month period before their index ED visit, 37% of nonpersistent patients were dispensed neither asthma reliever nor controller medications. Patients that do not meet HEDIS criteria for persistent asthma account for a substantial percentage of asthma-related ED visits. These patients have a history of low use of asthma medications before their ED visit. PMID:18321427

    Purpose: Report the results of using a permanently implantable dosimeter in radiation therapy: determine specific adverse events, degree of migration, and acquire dose measurements during treatment to determine difference between expected and measured dose. Methods and Materials: The Dose Verification System is a wireless, permanently implantable metal-oxide semiconductor field-effect transistor dosimeter using a bidirectional antenna for power and data transfer. The study cohort includes 36 breast (33 patients received two devices) and 29 prostate (21 patients received two devices) cancer patients. A total of 1,783 and 1,749 daily dose measurements were obtained on breast and prostate patients, respectively. The measurements were compared with the planned expected dose. Biweekly computed tomography scans were obtained to evaluate migration and the National Cancer Institute's Common Toxicity Criteria, version 3, was used to evaluate adverse events. Results: Only Grade I/II adverse events of pain and bleeding were noted. There were only four instances of dosimeter migration of >5 mm from known factors. A deviation of {>=}7% in cumulative dose was noted in 7 of 36 (19%) for breast cancer patients. In prostate cancer patients, a {>=}7% deviation was noted in 6 of 29 (21%) and 8 of 19 (42%) during initial and boost irradiation, respectively. The two patterns of dose deviation were random and systematic. Some causes for these differences could involve organ movement, patient movement, or treatment plan considerations. Conclusions: The Dose Verification System was not associated with significant adverse events or migration. The dosimeter can measure dose in situ on a daily basis. The accuracy and utility of the dose verification system complements current image-guided radiation therapy and intensity-modulated radiation therapy techniques.

    Primary biliary cholangitis (PBC), previously known as primary biliary “cirrhosis”, is a rare autoimmune liver disease characterized by the hallmark autoantibodies to mitochondrial antigens and immune-mediated destruction of small bile duct epithelial cells leading to cholestasis and cirrhosis. Surprisingly, while immune modulators have not been effective in the treatment of PBC, supplementation with the hydrophilic bile acid (BA) ursodeoxycholic acid (UDCA) has been demonstrated to slow the disease progression. However, a significant minority of PBC patients do not have a complete response to UDCA and remain at risk of continued disease progression. Although the mechanisms of action are not well understood, UDCA provided proof of concept for BA therapy in PBC. Obeticholic acid (OCA), a novel derivative of the human BA chenodeoxycholic acid, is a potent agonist of the nuclear hormone receptor farnesoid X receptor, which regulates BA synthesis and transport. A series of clinical trials of OCA in PBC, primarily in combination with UDCA, have established that OCA leads to significant reductions in serum alkaline phosphatase that are predicted to lead to improved clinical outcomes, while dose-dependent pruritus has been the most common adverse effect. On the basis of these studies, OCA was given conditional approval by the US Food and Drug Administration with plans to establish the long-term clinical efficacy of OCA in patients with advanced PBC.

    The aim of this study was to assess the influence of cognitive behavioural therapy (CBT) on chronic haemodialysis (HD) patients' ability to achieve fluid intake related behavioural objectives. This one group before and after quasi-experiment consisted of a four-week base-line phase, a six-week intervention phase and a four-week follow-up phase. Interventions included self-contract, reinforcement and self-monitoring. Participants were 10 Japanese HD outpatients. The average achievement of the fluid intake objective in the intervention phase was 65%. Fifty percent of participants achieved their objectives at least 3/4 of the time without individualised reinforcement. CBT was effective in helping patients change their fluid intake behaviours.

    Occult endometrial cancer is occasionally discovered in women with Lynch syndrome undergoing risk-reducing hysterectomy. The case presented here demonstrates that preoperative endometrial sampling can help detect these occult cancers; however, there are currently no recommendations for this preoperative intervention. A 50-year-old woman with Lynch syndrome underwent endometrial sampling prior to planned risk-reducing hysterectomy and bilateral salpingo-oophorectomy. The endometrial biopsy demonstrated a serous endometrial cancer. The patient was counselled regarding the diagnosis and revised operative plan, which now included staging, prior to surgery. Although the prevalence of occult endometrial cancer at the time of risk-reducing surgery in women with Lynch syndrome remains unknown, preoperative endometrial sampling may allow for improved patient counselling and surgical planning in this population, and can help avoid a subsequent surgery for staging.

    We reviewed the Chinese and English literature for efficacy and tolerability data as well as pharmacological properties of ropivacaine in Chinese patients. Ropivacaine is a long-acting amide local anesthetic agent that elicits nerve block via reversible inhibition of sodium ion influx in nerve fibers. The available evidence in the literature on anesthesia practice indicates that ropivacaine produces equally surgical sensory block and postoperative and obstetrics analgesia with good maternal and fetal outcome to those of bupivacaine or levobupivacaine. It appears to be associated with comparable onset, quality, and duration of sensory block, but with a lower incidence or grade of motor block, compared to bupivacaine. The satisfaction of both patients and surgeons is high when ropivacaine is used. Thus, ropivacaine appears to be an important option for regional anesthesia and for the management of postoperative and labor pain, with its enhanced sensorimotor differentiation blockage at lower concentrations and enhanced safety at higher concentrations.

    PubMed

    2015-04-01

    Hydroxyethyl starch (hetastarch) is a synthetic glucose compound with extensive clinical use as a volume expander. Because of its red blood cell-sedimenting properties, hetastarch plays a major role in preparation of granulocyte products. Recent concerns have been raised about the use of hetastarch in critically ill patients for the development of renal injury and other severe adverse events. In contrast, granulocyte donors receive much less of this compound during collection procedures, and over many years, minimal toxicity has been documented in these individuals. Furthermore, granulocyte products contain very little hetastarch, and ill effects on renal function have not been associated with their administration. This review assesses available information about the toxicity profile of hetastarch in critically ill patients requiring a volume expander as well as granulocyte donors and recipients. Because of the lack of toxicity in these latter two groups, hetastarch should be available for preparation of granulocyte products and their administration. PMID:25315227

    Background The revascularization strategy of the left main disease is determinant for clinical outcomes. Objective We sought to 1) validate and compare the performance of the SYNTAX Score 1 and 2 for predicting major cardiovascular events at 4 years in patients who underwent unprotected left main angioplasty and 2) evaluate the long-term outcome according to the SYNTAX score 2-recommended revascularization strategy. Methods We retrospectively studied 132 patients from a single-centre registry who underwent unprotected left main angioplasty between March 1999 and December 2010. Discrimination and calibration of both models were assessed by ROC curve analysis, calibration curves and the Hosmer-Lemeshow test. Results Total event rate was 26.5% at 4 years.The AUC for the SYNTAX Score 1 and SYNTAX Score 2 for percutaneous coronary intervention, was 0.61 (95% CI: 0.49-0.73) and 0.67 (95% CI: 0.57-0.78), respectively. Despite a good overall adjustment for both models, the SYNTAX Score 2 tended to underpredict risk. In the 47 patients (36%) who should have undergone surgery according to the SYNTAX Score 2, event rate was numerically higher (30% vs. 25%; p=0.54), and for those with a higher difference between the two SYNTAX Score 2 scores (Percutaneous coronary intervention vs. Coronary artery by-pass graft risk estimation greater than 5.7%), event rate was almost double (40% vs. 22%; p=0.2). Conclusion The SYNTAX Score 2 may allow a better and individualized risk stratification of patients who need revascularization of an unprotected left main coronary artery. Prospective studies are needed for further validation. PMID:27007223

    2010-01-01

    Hyponatremia is an electrolyte disorder frequently observed in several clinical settings and common in hospitalized patients with decompensated heart failure (HF). It is caused by deregulation of arginine vasopressin (AVP) homeostasis associated with water retention in hypervolemic or in euvolemic states. While hypervolemic hypotonic hyponatremia is also seen in advanced liver cirrhosis, renal failure, and nephrotic syndrome, the bulk of evidence associating this electrolyte disorder to increasing morbidity and mortality can be found in the HF literature. Hospitalized HF patients with low serum sodium concentration have lower short-term and long-term survival, longer hospital stay and increased readmission rates. Conventional therapeutic approaches, ie, restriction of fluid intake, saline and diuretics, can be effective, but often the results are unpredictable. Recent clinical trials have demonstrated the effectiveness of nonpeptide AVP receptor antagonists (vaptans) in the treatment of hyponatremia. The vaptans induce aquaresis, an electrolyte-sparing excretion of free water resulting in the correction of serum sodium concentrations and plasma osmolality, without activation of the renin-angiotensin-aldosterone system (RAAS) or changes in renal function and blood pressure. Further prospective studies in a selected congestive HF population with hyponatremia, using clinical-status titrated dose of tolvaptan, are needed to determine whether serum sodium normalization will be translated into a better long-term prognosis. This review will focus on recent clinical trials with tolvaptan, an oral V2 receptor antagonist, in HF patients. The ability of tolvaptan to safely increase serum sodium concentration without activating the RAAS or compromising renal function and electrolyte balance makes it an attractive agent for treating hyponatremic HF patients.

    Introduction The increasing rate of patient exposure to radiation from computerized tomography (CT) raises questions about appropriateness of utilization. There is no current standard to employ informed consent for CT (ICCT). Our study assessed the relationship between informed consent and CT utilization in emergency department (ED) patients. Methods An observational multiphase before-after cohort study was completed from 4/2010–5/2011. We assessed CT utilization before and after (Time I/Time II) the implementation of an informed consent protocol. Adult patients were included if they presented with symptoms of abdominal/pelvic pathology or completed ED CT. We excluded patients with pregnancy, trauma, or altered mental status. Data on history, exam, diagnostics, and disposition were collected via standard abstraction tool. We generated a multivariate logistic model via stepwise regression, to assess CT utilization across risk groups. Logistic models, stratified by risk, were generated to include study phase and a propensity score that controlled for potential confounders of CT utilization. Results 7,684 patients met inclusion criteria. In PHASE 2, there was a 24% (95% CI [10–36%]) reduction in CT utilization in the low-risk patient group (p<0.002). ICCT did not affect CT utilization in the high-risk group (p=0.16). In low-risk patients, the propensity score was significant (p<0.001). There were no adverse events reported during the study period. Conclusion The implementation of ICCT was associated with reduced CT utilization in low-risk ED patients. ICCT has the potential to increase informed, shared decision making with patients, as well as to reduce the risks and cost associated with CT. PMID:26759646

    Background and Aims. Upper endoscopy is a valuable tool in the workup of gastrointestinal (GI) complaints. The purpose of this study is to determine cost and yield of taking biopsies in a normal upper GI tract. Methods. This is a retrospective study where all upper GI biopsies were identified between May 2012 and April 2013, at a tertiary care center. Clinical, procedural, and pathology reports were reviewed to identify patient demographics, procedure information, and pathology diagnosis. Results. Biopsies of the upper GI tract were taken in 1297 patients with normal upper endoscopies. In patients with normal upper endoscopy, 22% of esophageal, 44% of gastric, and 12% of duodenal biopsies were abnormal. The most frequent abnormality was reflux esophagitis in 16% of esophageal biopsies, chronic gastritis in 23% of gastric biopsies, and increased intraepithelial lymphocytes in 6% of duodenal biopsies. The additional cost for taking biopsies in a normal upper GI tract for a diagnosis of eosinophilic esophagitis was $2963 Canadian (CAD), H. pylori associated gastritis was $1404 CAD, and celiac disease was $3024 CAD. Conclusions. The yield of biopsy in normal upper endoscopy varied with location, but the additional expense can be costly and should be tailored to appropriate clinical situations. PMID:27478819

    Strategy, Management and Health PolicyEnabling Technology, Genomics, ProteomicsPreclinical ResearchPreclinical Development Toxicology, Formulation Drug Delivery, PharmacokineticsClinical Development Phases I-III Regulatory, Quality, ManufacturingPostmarketing Phase IV There is an increasing need for the standardization of platelet function and coagulation testing for the assessment of antithrombotic therapies. Investigators continue to strive to identify ideal laboratory testing and monitoring procedures for acquired and inherited platelet function defects as well as for evaluating patient status when treated with existing or emerging antithrombotics. These therapies are used primarily in the treatment of ischemic complications. In patients receiving antithrombotic therapy, the balance between hemostasis and thrombosis is a challenge as there is an ongoing risk for bleeding when patients are receiving antiplatelet agents or anticoagulants to lessen their risk for secondary thrombotic events. There are several diverse tests for monitoring anticoagulant therapy; however, as new agents are developed, more specific tests will be required to directly assess these agents in relationship to overall coagulation status. Research in the platelet biology field is ongoing to provide point-of-care methodologies for the assessment of platelet reactivity in terms of both bleeding and thrombosis risk. Currently there are no instruments that reliably assess the risk of bleeding. The challenges that routinely faced are the complexity of physiology, the need for standardization of platelet testing methodology, and the necessity for appropriate interpretation of the test results.

    Abstract The prognosis of breast cancer occurs in young women is usually poor. Red cell distribution width (RDW), 1 of many routinely examined parameters, has recently been proposed as a prognostic marker in solid tumors. The aim of our study was to assess the predictive value of RDW for survival in young women with breast cancer. We reviewed 203 consecutive young female patients (under 40) with invasive breast cancer diagnosed at the First Affiliated Hospital of Wenzhou Medical University between January 2008 and December 2012. Preoperational RDW, clinicopathological information, and prognostic data were collected. RDW levels were divided into 2 groups: 161 patients with low RDW (≤13.75%) and 42 patients with high RDW (>13.75%). Clinicopathological differences between the 2 groups were calculated by chi-squared test and Wilcoxon rank-sum test. Kaplan–Meier survival analysis and Cox proportional hazard regression analyses were used to examine the effect of RDW on survival. We found that high RDW was significantly associated with larger tumor size (P = 0.002), positive lymph node metastases (P = 0.011), and advanced stages (P = 0.004). Patients with high RDW showed significantly lower disease-free survival (DFS; P < 0.001) and lower overall survival (OS) rate (P < 0.001) than patients with low RDW. Moreover, the Cox regression multivariate analysis revealed that high pretreatment DRW was independently correlated with poor DFS and OS, with hazard ratio 4.819 (95% confidence interval [CI] 2.291–10.138, P < 0.001) and 5.887 (95% CI 1.666–20.802, P = 0.006), respectively. In conclusion, our study demonstrated that pretreatment RDW may be associated with DFS and OS in young women with breast cancer. Further validation and feasibility studies are required before the result of our study can be considered for clinical practice. PMID:27124030

    Background. Skin cancer is the most commonly diagnosed form of cancer in the United States (US). However, knowledge, behaviors, and attitudes regarding sun protection vary among the general population. The purpose of this study is to examine sun protection behaviors of low-income primary care patients and assess the association between these health behaviors and the self-efficacy, susceptibility, and skin cancer awareness. Methods. Uninsured primary care patients utilizing a free clinic (N = 551) completed a self-administered survey in May and June 2015. Results. Using sunscreen was the least common tactic among the participants of this study. Skin cancer awareness and self-efficacy are important to improve sun protection behaviors. Spanish speakers may have lower levels of skin care awareness compared to US born and non-US born English speakers. Male and female participants use different sun protection methods. Conclusion. It is important to increase skin cancer awareness with self-efficacy interventions as well as education on low-cost sun protection methods. Spanish speaking patients would be a target population for promoting awareness. Male and female patients would need separate gender-specific sun protection education. Future studies should implement educational programs and assess the effectiveness of the programs to further promote skin cancer prevention among underserved populations. PMID:26425119

    Febrile neutropenia (FN) is a common complication among patients with chemotherapy-induced myelotoxicity and is associated with a number of negative outcomes including prolonged hospitalization, increased medical costs, increased risk of mortality, dose reductions, and delays. Granulocyte-colony-stimulating factor (G-CSF), granulocyte–macrophage-colony stimulating factor (GM-CSF), and pegylated G-CSF are effective at reducing risk and duration of neutropenia-related events. However, despite guidelines, the use of G-CSF and pegylated G-CSF in the United States has not been consistent and pattern of care studies have focused primarily on G-CSF. A number of studies found that G-CSF is underutilized in patients undergoing chemotherapy treatments associated with a high risk of FN, while being over utilized in patients with a low-risk FN. Wide variations in overuse, underuse, and misuse of G-CSF are associated with a number of physician and patient factors. Improved awareness of the guidelines, feedback to providers regarding proper usage, and understanding of chemotherapy regimens associated with very low risks as well as high risks (>20%) of FN is some of the approaches that could lead to improving care.

    A collaborative care model (CCM) has been implemented for management of depression. This paper studies the impact that the CCM had on cost measures for the period of six months after initial diagnosis of depression compared to patients receiving usual care (UC). There was a significant increase in the CPT costs for the six months following diagnosis in the CCM group ($451.35 vs. $323.50, P < 0.001). The average CPT cost rank and CPT cost differential were also significantly increased in the CCM group. The adjusted means of the CPT costs were (when controlling for prior utilization) $452.11 for the CCM group and $322.09 for UC (P < 0.001). In the CCM group; there were 161 patients (73.5%) that achieved a clinical response for their depression compared to the UC group, which had a 15.1% (18/119) response rate (P < 0.001). There also was a significant difference between the groups in those who were symptoms free of their depression (PHQ-9 score < 5), with the CCM having 59.4% of the patients symptom-free compared to 10.9% of the UC group (P < 0.001). In this group of patients, CCM is associated with markedly improved clinical outcomes for depression, however with a modest short-term increase in CPT costs. PMID:23804062

    Background Different Insulin-like Growth Factor Binding Proteins (IGFBPs) have been investigated as potential biomarkers in several types of tumors. In this study, we examined both IGFBP-3 and -4 levels in tissues and sera of melanoma patients representing different stages of melanoma progression. Methods The study cohort consisted of 132 melanoma patients (primary, n = 72; metastatic, n = 60; 64 Male, 68 Female; Median Age = 56) prospectively enrolled in the New York University School of Medicine Interdisciplinary Melanoma Cooperative Group (NYU IMCG) between August 2002 and December 2006. We assessed tumor-expression and circulating sera levels of IGFBP-3 and -4 using immunohistochemistry and ELISA assays. Correlations with clinicopathologic parameters were examined using Wilcoxon rank-sum tests and Spearman-rank correlation coefficients. Results Median IGFBP-4 tumor expression was significantly greater in primary versus metastatic patients (70% versus 10%, p = 0.01) A trend for greater median IGFBP-3 sera concentration was observed in metastatic versus primary patients (4.9 μg/ml vs. 3.4 μg/ml, respectively, p = 0.09). However, sera levels fell within a normal range for IGFBP-3. Neither IGFBP-3 nor -4 correlated with survival in this subset of patients. Conclusion Decreased IGFBP-4 tumor expression might be a step in the progression from primary to metastatic melanoma. Our data lend support to a recently-described novel tumor suppressor role of secreting IGFBPs in melanoma. However, data do not support the clinical utility of measuring levels of IGFBP-3 and -4 in sera of melanoma patients. PMID:19025658

    Most cancer patients experience nausea and vomiting after surgery. Today, many methods of treatment have been developed and used for the control of such symptoms. The most important are drug therapy, relaxation, oxygen therapy and gas therapy. In addition, dexamethasone, massage therapy and using a Venturi mask have also proven effective. Due to the nature of gas consumption which leads to nausea it is recommended that use of N2O in the operating room be avoided or applied in combination with oxygen or other gases with fewer complications.

    This retrospective cohort study describes the patterns of antibiotic use for the treatment of ventilator-associated pneumonia (VAP) in the Calgary Zone of Alberta Health Services. Timing, appropriateness, and duration of antibiotics were evaluated in two hundred consecutive cases of VAP derived from 4 adult intensive care units (ICU). Antibiotic therapy was initiated in less than 24 hours from VAP diagnosis in 83% of cases. Although most patients (89%) received empiric therapy that demonstrated in vitro sensitivity to the identified pathogens, only 24% of cases were congruent with the 2008 Association of Medical Microbiology and Infectious Disease (AMMI) guidelines. Both ICU (p = 0.001) and hospital (p = 0.015) mortality were significantly lower and there was a trend for shorter ICU length of stay (p = 0.051) in patients who received appropriate versus inappropriate initial antibiotics. There were no outcome differences related to compliance with AMMI guidelines. This exploratory study provides insight into the use of antimicrobials for the treatment of VAP in a large Canadian health region. The discordance between the assessments of appropriateness of empiric therapy based on recovered pathogens versus AMMI guidelines is notable, emphasizing the importance of using as much as possible local microbiologic and antimicrobial resistance data.

    Background: The outreach of YouTube may have a dramatic role in the widespread dissemination of knowledge on implantable cardioverter devices (ICD). Aims: This study was designed to review and analyze the information available on YouTube pertaining to implantable cardiac devices such as implantable cardioverter defibrillators (ICDs) and pacemakers. Materials and Methods: YouTube was queried for the terms “ICD”, “Implantable Cardioverter Defibrillator”, and “Pacemaker”. The videos were reviewed and categorized as according to content; number of views and “likes” or “dislikes” was recorded by two separate observers. Results: Of the 55 videos reviewed, 18 of the videos were categorized as patient education, 12 were advertisements, 8 were intraoperative videos documenting the device implantation procedures, 7 of the videos were produced to document personal patient experiences, and 4 were categorized as documentation of a public event. 3 were intended to educate health care workers. The remaining 3 were intended to raise public awareness about sudden cardiac death. The videos portraying intraoperative procedures generated the most “likes” or “dislikes” per view. Conclusion: While YouTube provides a logical platform for delivery of health information, the information on this platform is not regulated. Initiative by reputed authorities and posting accurate information in such platform can be a great aid in public education regarding device therapy. PMID:25077075

    Stroke is one of the leading causes for long-term disability in the United States. Robot-aided rehabilitation has facilitated the functional recovery of chronic stroke victims. In this study, two models were developed to aid the design of a rehabilitation robot driven by pneumatic muscle (PM) actuators, which will be applied in the treatment of the upper-limb sensorimotor deficits of stroke patients. A biomechanical model of the musculoskeletal system with exoskeleton robot powered by PM was implemented to examine the initial parameters of PM based on the kinematics and dynamics of PM assisted arm-reaching and self-feeding tasks. The outputs of the model provided guidelines for the optimal design of robot's structure. Additionally, the model can determine the necessary auxiliary force and the activation timing pattern of each PM during multi-joint coordinated movement for the robot's dynamic control. Inverse-dynamics biomechanical model generates the joint torques required to perform the movement. In addition to the musculoskeletal model, we propose a simple method to estimate the self-generated net muscle torques, therefore, to provide quantitative assessment of motor improvement of stroke patients during the therapy.

    Background Accurate reporting of patient symptoms is critical for diagnosis and therapeutic monitoring in psychiatry. Smartphones offer an accessible, low-cost means to collect patient symptoms in real time and aid in care. Objective To investigate adherence among psychiatric outpatients diagnosed with major depressive disorder in utilizing their personal smartphones to run a custom app to monitor Patient Health Questionnaire-9 (PHQ-9) depression symptoms, as well as to examine the correlation of these scores to traditionally administered (paper-and-pencil) PHQ-9 scores. Methods A total of 13 patients with major depressive disorder, referred by their clinicians, received standard outpatient treatment and, in addition, utilized their personal smartphones to run the study app to monitor their symptoms. Subjects downloaded and used the Mindful Moods app on their personal smartphone to complete up to three survey sessions per day, during which a randomized subset of PHQ-9 symptoms of major depressive disorder were assessed on a Likert scale. The study lasted 29 or 30 days without additional follow-up. Outcome measures included adherence, measured by the percentage of completed survey sessions, and estimates of daily PHQ-9 scores collected from the smartphone app, as well as from the traditionally administered PHQ-9. Results Overall adherence was 77.78% (903/1161) and varied with time of day. PHQ-9 estimates collected from the app strongly correlated (r=.84) with traditionally administered PHQ-9 scores, but app-collected scores were 3.02 (SD 2.25) points higher on average. More subjects reported suicidal ideation using the app than they did on the traditionally administered PHQ-9. Conclusions Patients with major depressive disorder are able to utilize an app on their personal smartphones to self-assess their symptoms of major depressive disorder with high levels of adherence. These app-collected results correlate with the traditionally administered PHQ-9. Scores

    Background How well the 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification prognosticates for Asian patients with COPD is unknown. Objective The authors aimed to study the predictive utility of the GOLD 2011 classification for exacerbations and mortality as compared with other multidimensional tools in an Asian population. Methods In all, 1,110 COPD patients were prospectively followed between March 2008 and March 2013. They were classified using the 2011 and 2007 GOLD guidelines, modified Medical Research Council score, St. George’s Respiratory Questionnaire (SGRQ), and Body mass index, Obstruction, Dyspnea (BOD) index. Outcome measures were exacerbations and mortality. Multivariable survival analyses and receiver operating characteristic (ROC) curves were used to assess the different classification systems. Results Time-to-event analyses demonstrated earlier exacerbations in 2011’s GOLD D when compared with GOLD A (hazard ratio [HR] 0.54, 95% confidence interval [CI]: 0.31–0.95, P=0.032) and GOLD B (HR 0.62, 95% CI: 0.45–0.85, P=0.003) and higher mortality when compared with GOLD A (HR 0.37, 95% CI: 0.16–0.88, P=0.025) and GOLD B (HR 0.46, 95% CI: 0.31–0.70, P<0.001). The areas under the ROC curve for GOLD 2011, GOLD 2007, modified Medical Research Council, St. George’s Respiratory Questionnaire, and BOD index were 0.62, 0.59, 0.61, 0.60, and 0.61, respectively, for the prediction of exacerbations and 0.71, 0.70, 0.71, 0.71, and 0.72, respectively, for the prediction of mortality (ROC comparator, P>0.05). Conclusion The 2011 GOLD classification predicts exacerbations and mortality moderately well in Asian COPD patients. Its prognostic utility is similar to that of other multidimensional systems.

    A survey of 8,034 primary care patients in a health maintenance organization examined the relationship between alcohol consumption and health care costs and service use. Costs were estimated from service use data for 1 year before and 2 years after study enrollment. No strong, consistent relationships were identified between multiple indicators of drinking patterns and either health care costs or service use. Compared with total costs among very light drinkers, former drinkers were higher, lifetime abstainers were similar, and persons in the higher drinking levels tended to have lower but not significantly different costs. Drinking patterns did not appear to be an important predictor of short-term health care costs or service use in this setting. Further study of former drinkers is warranted to examine the role of alcohol-related illnesses in the decision to quit drinking. PMID:11732242

    2013-09-01

    Autism is a pervasive developmental disorder that affects a growing number of children in the United States each year. It is characterized by substantive differences in brain structure and function that lead to long-term cognitive and social deficits. These differences, combined with the increasing prevalence of autism in children, warrant the need for development of innovative, cost-effective and widely available alternative and complementary therapies. Motion gaming has the potential to be highly efficacious as a therapeutic technique to aid in developing memory, facial recognition, motor skills and social integration in the pediatric autistic population. This paper outlines the major deficits in the brains of individuals with autism and describes how the use of motion gaming could capitalize on the individual strengths of each patient, leading to improvements in a variety of deficits.

    EEG has been used to study acute stroke for decades; however, because of several limitations EEG-based measures rarely inform clinical decision-making in this setting. Recent advances in EEG hardware, recording electrodes, and EEG software could overcome these limitations. The present study examined how well dense-array (256 electrodes) EEG, acquired with a saline-lead net and analyzed with whole brain partial least squares (PLS) modeling, captured extent of acute stroke behavioral deficits and varied in relation to acute brain injury. In 24 patients admitted for acute ischemic stroke, 3 min of resting-state EEG was acquired at bedside, including in the ER and ICU. Traditional quantitative EEG measures (power in a specific lead, in any frequency band) showed a modest association with behavioral deficits [NIH Stroke Scale (NIHSS) score] in bivariate models. However, PLS models of delta or beta power across whole brain correlated strongly with NIHSS score (R(2) = 0.85-0.90) and remained robust when further analyzed with cross-validation models (R(2) = 0.72-0.73). Larger infarct volume was associated with higher delta power, bilaterally; the contralesional findings were not attributable to mass effect, indicating that EEG captures significant information about acute stroke effects not available from MRI. We conclude that 1) dense-array EEG data are feasible as a bedside measure of brain function in patients with acute stroke; 2) high-dimension EEG data are strongly correlated with acute stroke behavioral deficits and are superior to traditional single-lead metrics in this regard; and 3) EEG captures significant information about acute stroke injury not available from structural brain imaging.

    The pattern of distribution of gallium uptake in the thorax was investigated in patients (pts) with AIDS. Eleven pts (ages 18-53), all active homosexual males suspected of having acute pulmonary infection were studied. Ga lung scans were performed at 24-48 and/or 72 hrs. post injection. The diagnosis of AIDS was based on appropriate clinical and laboratory findings. The Ga activity in the lung was graded from zero = background to 4+ which is > liver activity. Eight of eleven pts have positive Ga scan while seven of eleven pts had positive CXR. Six pts had both positive CXR and Ga scan. One pt had a positive Ga scan with negative CXR, and one with positive CXR and negative Ga scan. The positive Ga scans included 3 pts with 4+ diffuse uptake, two pts with 2+ diffuse uptake, two pts with 1+ diffuse uptake, and two with hilar node uptake. Three pts have focal increased uptake superimposed on diffuse uptake. Two pts with 4+ diffuse uptake had mild abnormality on their CXR. One pt with 4+ uptake in the initial scan shows decreased activity on follow-up with clinical improvement after therapy. Thus, all but two pts with positive Ga scans had diffuse lung uptake. These two patients alone had B cell immunoblastic sarcoma and oral candidiasis. The pattern of Ga lung uptake in pts with AIDS reveal that a majority of positive scans are diffuse (6/8) and the intensity may suggest more active disease than CXR (2 normal) and, thus, the study may be useful in detecting changes from atypical pulmonary infection in this population.

    Exposure to stressful life events, mood disorder, and health care utilization were evaluated in 102 low-income, primarily minority patients receiving behavioral health and medical services at a safety-net primary care clinic. Exposure to major stressors was far higher in this sample than in the general population, with older patients having lower stress scores. Proportions of patients who met the criteria for clinical depression and anxiety were higher than in normative samples of primary care patients. Stress exposure was higher in the patients who met the criterion for clinical anxiety but was unrelated to clinical depression. Contrary to expectation, anxiety, depression, or stress exposure was not related to service utilization. Latter findings are discussed in terms of the influence of the provision of behavioral health services, the highly skewed distribution of major stressor scores, and the likely greater influence of individual differences in minor stressor exposure on utilization in this population.

    Vascular endothelial growth factor (VEGF), matrix metalloproteinase-9, and tissue inhibitor of metalloproteinase-1 may play a role in the pathogenesis of cancer disease. We investigated their levels and utility in comparison to cancer antigen (CA) 15-3 in patients with breast cancer (BC) and in relation to the control groups. The study included 100 women with BC, 50 patients with benign breast tumor, and 50 healthy women. The plasma levels of the tested parameters were determined using enzyme-linked immunosorbent assay, while CA 15-3 with chemiluminescent microparticle immunoassay. The results demonstrated significant differences in the concentration of the tested parameters and CA 15-3 between groups of patients with BC and healthy patients or patients with benign breast tumor. The plasma levels of VEGF and tissue inhibitor of metalloproteinase-1 were significantly higher in advanced tumor stages. The tested parameters were comparable to CA 15-3 values of the diagnostic sensitivity, specificity, the predictive values of positive and negative test results, and the area under the receiver-operating characteristic curve. The combined use of the tested parameters with CA 15-3 resulted in the increase in sensitivity, negative predictive value, and area under the receiver-operating characteristic curve, especially in the combination of VEGF with tumor marker (84%, 73%, 0.888, respectively). These findings suggest the usefulness of the tested parameters in the diagnosis of BC. VEGF, especially in combination with CA 15-3, showed the highest usefulness in the diagnosis of early BC.

    Aim To evaluate the diagnostic accuracy and clinical utility of the fibrosis index based on the four factors (FIB-4), aspartate aminotransferase -to-platelet ratio index (APRI), and aspartate aminotransferase–alanine aminotransferase ratio index (AAR) for predicting liver fibrosis in patients with HBV infection. Methods From January 2006 to December 2010,a total of 1543 consecutive chronic hepatitis B(CHB) patients who underwent liver biopsies were enrolled. FIB-4,APRI, and AAR were calculated.The areas under the receiver-operating characteristic curves (AUROCs) were calculated to assess the diagnostic accuracy of these models.The AUROCs of these models were compared by DeLong’s test.For further comparisons in different studies,the AUROCs were adjusted to conduct Adjusted AUROCs(ADjAUROCs) according to the prevalence of fibrosis stages using the difference between advanced and nonadvanced fibrosis (DANA). Results For prediction of significant fibrosis,severe fibrosis,and cirrhosis,the AUROCs of FIB-4 were 0.646(ADjAUROC 0.717),0.670(ADjAUROC 0.741), and 0.715(ADjAUROC 0.786) respectively;whereas it were 0.656(ADjAUROC 0.727),0.653(ADjAUROC 0.724) and 0.639(ADjAUROC 0.710) for APRI, 0.498(ADjAUROC 0.569),0.548(ADjAUROC 0.619) and 0.573(ADjAUROC 0.644) for AAR. The further comparisons demonstrated that there were no significant differences of AUROCs between FIB-4 and APRI in predicting significant and severe fibrosis(P > 0.05),while FIB-4 was superior to APRI in predicting cirrhosis(P < 0.001). Further subgroup analysis demonstrated that the diagnostic accuracy of FIB-4 and APRI in patients with normal alanine aminotransferase(ALT) were higher than that in patients with elevated ALT. Conclusions The results demonstrated that FIB-4 and APRI are useful for diagnosis of fibrosis. FIB-4 and APRI have similar diagnostic accuracy in predicting significant and severe fibrosis,while FIB-4 is superior to APRI in predicting cirrhosis. The clinical utility of FIB-4 and APRI

    Sickle cell nephropathy (SCN) is associated with iron/heme deposition in proximal renal tubules and related acute tubular injury (ATI). Here we report the utility of iron staining in differentiating causes of renal allograft dysfunction in patients with a history of sickle cell disease. Case 1: the patient developed acute allograft dysfunction two years after renal transplant. Her renal biopsy showed ATI, supported by patchy loss of brush border and positive staining of kidney injury molecule-1 in proximal tubular epithelial cells, where diffuse increase in iron staining (2+) was present. This indicated that ATI likely resulted from iron/heme toxicity to proximal tubules. Electron microscope confirmed aggregated sickle RBCs in glomeruli, indicating a recurrent SCN. Case 2: four years after renal transplant, the patient developed acute allograft dysfunction and became positive for serum donor-specific antibody. His renal biopsy revealed thrombotic microangiopathy (TMA) and diffuse positive C4d stain in peritubular capillaries. Iron staining was negative in the renal tubules, implying that TMA was likely associated with acute antibody-mediated rejection (AAMR, type 2) rather than recurrent SCN. These case reports imply that iron staining is an inexpensive but effective method in distinguishing SCN-associated renal injury in allograft kidney from other etiologies. PMID:26697257

    Objective To compare utilization and preventive care receipt among patients of federal Section 330 health centers (HCs) versus patients of other settings. Data Sources A nationally representative sample of adults from the Medical Expenditure Panel Survey (2004–2008). Study Design HC patients were defined as those with ≥50 percent of outpatient visits at HCs in the first panel year. Outcomes included utilization and preventive care receipt from the second panel year. We used negative binomial and logistic regression models with propensity score adjustment for confounding differences between HC and non-HC patients. Principal Findings Compared to non-HC patients, HC patients had fewer office visits (adjusted incidence rate ratio [aIRR], 0.63) and hospitalizations (aIRR, 0.43) (both p < .001). HC patients were more likely to receive breast cancer screening than non-HC patients (adjusted odds ratio [aOR] 2.78, p < .01). In subgroup analyses, uninsured HC patients had fewer outpatient and emergency room visits and were more likely to receive dietary advice and breast cancer screening compared to non-HC patients. Conclusions Health centers add value to the health care system by providing socially and medically disadvantaged patients with care that results in lower utilization and maintained or improved preventive care.

    Numerous reports describe unintended consequences of electronic health record implementation. Having previously described physicians' failures to recognize patient safety issues within our electronic health record simulation environment, we now report on our use of eye and screen-tracking technology to understand factors associated with poor error recognition during an intensive care unit-based electronic health record simulation. We linked performance on the simulation to standard eye and screen-tracking readouts including number of fixations, saccades, mouse clicks and screens visited. In addition, we developed an overall Composite Eye Tracking score which measured when, where and how often each safety item was viewed. For 39 participants, the Composite Eye Tracking score correlated with performance on the simulation (p = 0.004). Overall, the improved performance was associated with a pattern of rapid scanning of data manifested by increased number of screens visited (p = 0.001), mouse clicks (p = 0.03) and saccades (p = 0.004). Eye tracking can be successfully integrated into electronic health record-based simulation and provides a surrogate measure of cognitive decision making and electronic health record usability.

    AIM To determine healthcare resource utilization and the economic burden associated with wet age-related macular degeneration (AMD) in Thailand METHODS This study included patients diagnosed with wet AMD that were 60 years old or older, and had best corrected visual acuity (BCVA) measured at least two times during the follow-up period. We excluded patients having other eye diseases. Two separate sub-studies were conducted. The first sub-study was a retrospective cohort study; electronic medical charts were reviewed to estimate the direct medical costs. The second sub-study was a cross-sectional survey estimating the direct non-medical costs based on face-to-face interviews using a structured questionnaire. For the first sub-study, direct medical costs, including the cost of drugs, laboratory, procedures, and other treatments were obtained. For the second sub-study, direct non-medical costs, e.g. transportation, food, accessories, home renovation, and caregiver costs, were obtained from face-to-face interviews with patients and/or caregivers. RESULTS For the first sub-study, sixty-four medical records were reviewed. The annual average number of medical visits was 11.1±6.0. The average direct medical costs were $3 604±4 530 per year. No statistically-significant differences of the average direct medical costs among the BCVA groups were detected (P=0.98). Drug costs accounted for 77% of total direct medical costs. For direct non-medical costs, 67 patients were included. Forty-eight patients (71.6%) required the accompaniment of a person during the out-patient visit. Seventeen patients (25.4%) required a caregiver at home. The average direct non-medical cost was $2 927±6 560 per year. There were no statistically-significant differences in the average costs among the BCVA groups (P=0.74). Care-giver cost accounted for 87% of direct non-medical costs. CONCLUSION Our study indicates that wet AMD is associated with a substantial economic burden, especially concerning

    The purpose of this study was to determine the feasibility and acceptability of utilizing a smartphone based application to monitor compliance in patients with cardiac disease around discharge. For 60 days after discharge, patients' medication compliance, physical activity, follow-up care, symptoms, and reading of education material were monitored daily with the application. 16 patients were enrolled in the study (12 males, 4 females, age 55 ± 18 years) during their hospital stay. Five participants were rehospitalized during the study and did not use the application once discharged. Seven participants completed 1–30 days and four patients completed >31 days. For those 11 patients, medication reminders were utilized 37% (1–30-day group) and 53% (>31-day group) of the time, education material was read 44% (1–30) and 53% (>31) of the time, and physical activity was reported 25% (1–30) and 42% (>31) of the time. Findings demonstrated that patients with stable health utilized the application, even if only minimally. Patients with decreased breath sounds by physical exam and who reported their health as fair to poor on the day of discharge were less likely to utilize the application. Acceptability of the application to report health status varied among the stable patients. PMID:25574165

    The hypothesis in the conceptual model was that a user-driven innovation in presently available information and communication technology infrastructure would be able to meet patient and health professional users information needs and help them attain better health outcomes. An operational model was created to plan a trial on a sample diabetic population utilizing a randomized control trial design, assigning one randomly selected group of diabetics to receive electronic information intervention and analyse if it would improve their health outcomes in comparison with a matched diabetic population who would only receive regular medical intervention. Diabetes was chosen for this particular trial, as it is a major chronic illness in Malaysia as elsewhere in the world. It is in essence a position paper for how the study concept should be organized to stimulate wider discussion prior to beginning the study. PMID:19018906

    The Crit-Line™ monitor measures relative changes in intravascular blood volume during hemodialysis. The device is also used to monitor hematocrit and oxygen saturation. Using this device to decrease fluid volume has yielded inconsistent results on outcome measures such as hospitalization rates, erythropoietin utilization, and blood pressure reduction. Through a year-long deployment of the Crit-Line™ monitor, the Renal Research Institute (RRI) has shown that outcomes can be improved even in a busy dialysis clinic with attention to the details of how the device is utilized. In this paper, we are proposing areas of focus and methods that if properly implemented should yield improved clinical outcomes. Strong physician approval and enthusiasm coupled with clinical staff support have been shown to be vital to the success of this device in improving clinical outcomes. Even in this setting, inadequately and improperly trained staff have been identified as almost insurmountable impediments to adequate Crit-Line™ use. Our studies have shown that in facilities where staff turnover is high, procedures must be implemented to engage and train new staff immediately upon their arrival on the dialysis floor. Other issues that may lead to improper use of the Crit-Line™ monitor include incorrect target weight assessments, failure of staff to properly monitor patients during the treatment, and the over dependency of saline administration for cramps.

    Background Nonalcoholic fatty liver disease (NAFLD) is common in adults with extreme obesity and can impact long-term health and survival. Liver biopsy is the only accurate test for diagnosis and staging, but is invasive and costly. Non-invasive testing offers an attractive alternate, but the overall accuracy remains a significant issue. This study was conducted to determine the accuracy and clinical utility of preoperative ultrasound and liver transaminase levels, as well as intra-operative hepatic visual inspection, for assessing presence of NAFLD as confirmed by hepatic histology. Methods Data was collected prospectively from 580 morbidly obese adult patients who underwent Roux-en-Y gastric bypass surgery with intraoperative wedge biopsy between January 2004 and February 2009. Complete data for ultrasound, ALT and AST levels, and documented visual inspection was available for 513 patients. Results The prevalence of NAFLD was 69 % and that of NASH was 32 %. The individual non-invasive clinical assessments demonstrated low sensitivity, specificity, and accuracy for detecting the presence of steatosis, steatohepatitis, or fibrosis. The combination of normal or abnormal results for all tests improved predictive utility. Abnormal tests with all three assessments had a sensitivity of 95–98 % and a specificity of 28–48 % for major histologic findings in NAFLD/NASH. Normal tests with all three assessments had a sensitivity of 12–22 % and a specificity of 89–97 % for major histologic findings in NAFLD/NASH. Conclusions Although individual clinical tests for NAFLD have limited accuracy, the use of combined clinical tests may prove useful. PMID:26003548

    The clinical significance of ineffective esophageal motility (IEM) together with multiple rapid swallow (MRS) has not been yet evaluated in the Chicago Classification v3.0. This study evaluated the adjunctive role of MRS in IEM and determined the criteria of abnormal MRS to maximize the utility of IEM. We analyzed 186 patients showing IEM or normal esophageal motility (NEM), who underwent esophageal high-resolution impedance-manometry for esophageal symptoms. Two different criteria for abnormal MRS were applied to IEM subjects, resulting in 2 corresponding subgroups: IEM-A when distal contractile integral (DCI) ratio between an average wet swallows and MRS contraction was < 1 and IEM-B when MRS contraction DCI was <450 mm Hg-s-cm. One IEM subject inadequately performed MRS. Among the remaining 52 IEM subjects, 18 (34.6%) were classified into IEM-A and 23 (44.2%) into IEM-B. IEM subjects showed less complete bolus transit (median 0.0%, interquartile range 0.0-20.0% vs 60.0%, 30.0-80.0; P < 0.001) resulting in higher impaired bolus transit than NEM subjects (98.1% vs 66.9%, P = 0.001). IEM-B subjects showed additionally higher pathologic bolus exposure than NEM subjects (55.6% vs 29.3%, P = 0.001), whereas IEM-A subjects could not. Although IEM-B subjects had the highest prevalence of gastroesophageal reflux disease among the subjects groups, it did not reach statistical significance. In conclusion, IEM patients with abnormal MRS contraction have an increased risk of prolonged bolus clearance, poor bolus transit, and pathologic bolus exposure. IEM patients need to be assessed concerning whether MRS contraction DCI is < 450 mm Hg-s-cm to segregate clinically relevant patients. PMID:26448010

    The goal of this study was to determine the prognostic utility of the exercise thallium-201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization. Accordingly, 4 to 8 year (mean +/- 1SD, 4.6 +/- 2.6 years) follow-up data were obtained for all but one of 383 patients who underwent both exercise thallium-201 stress testing and cardiac catheterization from 1978 to 1981. Eighty-three patients had a revascularization procedure performed within 3 months of testing and were excluded from analysis. Of the remaining 299 patients, 210 had no events and 89 had events (41 deaths, nine nonfatal myocardial infarctions, and 39 revascularization procedures greater than or equal to 3 months after testing). When all clinical, exercise, thallium-201, and catheterization variables were analyzed by Cox regression analysis, the number of diseased vessels (when defined as greater than or equal to 50% luminal diameter narrowing) was the single most important predictor of future cardiac events (chi 2 = 38.1) followed by the number of segments demonstrating redistribution on delayed thallium-201 images (chi 2 = 16.3), except in the case of nonfatal myocardial infarction, for which redistribution was the most important predictor of future events. When coronary artery disease was defined as 70% or greater luminal diameter narrowing, the number of diseased vessels significantly (p less than .01) lost its power to predict events (chi 2 = 14.5). Other variables found to independently predict future events included change in heart rate from rest to exercise (chi 2 = 13.0), ST segment depression on exercise (chi 2 = 13.0), occurrence of ventricular arrhythmias on exercise (chi 2 = 5.9), and beta-blocker therapy (chi 2 = 4.3).

    AIM: To determine utility of transplant liver biopsy in evaluating efficacy of percutaneous transluminal angioplasty (PTA) for hepatic venous obstruction (HVOO). METHODS: Adult liver transplant patients treated with PTA for HVOO (2003-2013) at a single institution were reviewed for pre/post-PTA imaging findings, manometry (gradient with right atrium), presence of HVOO on pre-PTA and post-PTA early and late biopsy (EB and LB, < or > 60 d after PTA), and clinical outcome, defined as good (no clinical issues, non-HVOO-related death) or poor (surgical correction, recurrent HVOO, or HVOO-related death). RESULTS: Fifteen patients meeting inclusion criteria underwent 21 PTA, 658 ± 1293 d after transplant. In procedures with pre-PTA biopsy (n = 19), no difference was seen between pre-PTA gradient in 13/19 procedures with HVOO on biopsy and 6/19 procedures without HVOO (8 ± 2.4 mmHg vs 6.8 ± 4.3 mmHg; P = 0.35). Post-PTA, 10/21 livers had EB (29 ± 21 d) and 9/21 livers had LB (153 ± 81 d). On clinical follow-up (392 ± 773 d), HVOO on LB resulted in poor outcomes and absence of HVOO on LB resulted good outcomes. Patients with HVOO on EB (3/7 good, 4/7 poor) and no HVOO on EB (2/3 good, 1/3 poor) had mixed outcomes. CONCLUSION: Negative liver biopsy greater than 60 d after PTA accurately identifies patients with good clinical outcomes. PMID:26207170

    A qualitative study aimed at describing the situations experienced and the ethical dilemmas of nurses in the process of referring and receiving hospitalized patients by court order who require admission to the Intensive Care Unit (ICU). A partially structured interview was conducted with 10 nurses who worked in the ICU and 10 who worked in the Emergency Room (ER) in public and private hospitals in the metropolitan area of Porto Alegre, Brazil. The data was analyzed following the Semantic Analysis. The results indicated that nurses experienced ethical dilemmas associated with problems of overcrowding in emergency rooms and ICUs, poor specialized technology and orientation as to the benefits provided by law. We concluded that it is essential for nurses to participate in discussions that allow the planning of the different instances that have been promoting this often chaotic situation. PMID:23781732

    Bortezomib represents a new class of anti-cancer drugs, the proteasome inhibitors. We evaluated the in vitro activity of bortezomib with regard to tumour-type specificity and possible mechanisms of drug resistance in 115 samples of tumour cells from patients and in a cell-line panel, using the short-term fluorometric microculture cytotoxicity assay. Bortezomib generally showed dose-response curves with a steep slope. In patient cells, bortezomib was more active in haematological than in solid tumour samples. Myeloma and chronic myeloid leukaemia were the most sensitive tumour types although with great variability in drug response between the individual samples. Colorectal and kidney cancer samples were the least sensitive. In the cell-line panel, only small differences in response were seen between the different cell lines, and the proteasome inhibitors, lactacystin and MG 262, showed an activity pattern similar to that of bortezomib. The cell-line data suggest that resistance to bortezomib was not mediated by MRP-, PgP, GSH-; tubulin and topo II-associated MDR. Combination experiments indicated synergy between bortezomib and arsenic trioxide or irinotecan. The data support the current use of bortezomib but also points to its potential utility in other tumour types and in combination with cytotoxic drugs. PMID:19016012

    This study is an audit of the Somerset Court Advice and Assessment Service (CAAS) throughout its first year of implementation. It reports that the service successfully met the six desired objectives as set out in its Service Level Agreement. Further to this, it reports that the use of National Health Service electronic patient records within a court setting facilitated the provision of apposite and timely information to the court. Specific findings were that deliberate self-harm/suicidal ideation and mood disorders were the primary reasons for a person requiring CAAS involvement. Violence against the person, breach of orders and theft were the most prevalent categories of offending within this referred group. The prevalence of previous psychiatric history was significantly higher than found in comparable audits. It is likely that this is due to the efficacy of proactive and in vivo utilization of electronic patient records. Conclusions include the need to work in partnership with drug and alcohol agencies and the importance of recognizing that these services have significant clinical benefits for defendants with mental health problems, and the court system in terms of financial savings. We suggest ongoing audit is necessary to guide the development of other schemes in this pioneering service area. PMID:22833486

    This study aims to estimate the volume of unnecessarily utilized hospital outpatient services in Korea and quantify the total cost resulting from the inappropriate utilization. The analysis included a sample of 27,320,505 outpatient claims from the 2009 National Inpatient Sample database. Using the Charlson Comorbidity Index (CCI), patients were considered to have received 'unnecessary hospital outpatient utilization' if they had a CCI score of 0 and were concurrently admitted to hospital for treatment of a single chronic disease - hypertension (HTN), diabetes mellitus (DM), or hyperlipidemia (HL) - without complication. Overall, 85% of patients received unnecessary hospital services. Also hospitals were taking away 18.7% of HTN patients, 18.6% of DM and 31.6% of HL from clinics. Healthcare expenditures from unnecessary hospital outpatient utilization were estimated at: HTN (94,058 thousands USD, 38.6% of total expenditure); DM (17,795 thousands USD, 40.6%) and HL (62,876 thousands USD, 49.1%). If 100% of patients who received unnecessary hospital outpatient services were redirected to clinics, the estimated savings would be 104,226 thousands USD. This research proves that approximately 85% of hospital outpatient utilizations are unnecessary and that a significant amount of money is wasted on unnecessary healthcare services; thus burdening the National Health Insurance Service (NHIS) and patients.

We analyzed a retrospective clinical database of 60 patients with diabetic foot ulcers from the Diabetic Foot Unit (Complutense University, Madrid, Spain) between January 2012 and March 2014. For each patient, anteroposterior XR-plains were evaluated, and the ABI and toe-brachial index (TBI) were assessed by an experienced clinician. To analyze the correlation among quantitative variables, we applied the Pearson correlation coefficient. Fifty percent (n = 9/18) of our patients with a normal ABI and RAC had a TBI < 0.7 associated with peripheral arterial disease (PAD). In patients with RAC, the prevalence of a normal ABI (72%, 18/25) was higher than in patients without RAC (52%, 11/21). The Pearson correlation coefficient among the ABI and TBI in patients with an ABI < 1.4 (n = 46) was lesser (r = .484, P = .001) than in patients with an ABI < 1.4 but without RAC (n = 21; r = .686, P = .001). ABI values between 0.9 and 1.4 would be falsely considered as normal and could underestimate the prevalence of PAD, especially in patients with neuropathy, diabetic foot ulcers, or RAC.

    Purpose. Pain is multi-dimensional and may be better addressed through a holistic, biopsychosocial approach. Massage therapy is commonly practiced among patients seeking pain management; however, its efficacy is unclear. This systematic review and meta-analysis is the first to rigorously assess the quality of massage therapy research and evidence for its efficacy in treating pain, function-related and health-related quality of life outcomes across all pain populations. Methods. Key databases were searched from inception through February 2014. Eligible randomized controlled trials were assessed for methodological quality using SIGN 50 Checklist. Meta-analysis was applied at the outcome level. A diverse steering committee interpreted the results to develop recommendations. Results. Sixty high quality and seven low quality studies were included in the review. Results demonstrate massage therapy effectively treats pain compared to sham [standardized mean difference (SMD) = −.44], no treatment (SMD = −1.14), and active (SMD = −0.26) comparators. Compared to active comparators, massage therapy was also beneficial for treating anxiety (SMD = −0.57) and health-related quality of life (SMD = 0.14). Conclusion. Based on the evidence, massage therapy, compared to no treatment, should be strongly recommended as a pain management option. Massage therapy is weakly recommended for reducing pain, compared to other sham or active comparators, and improving mood and health-related quality of life, compared to other active comparators. Massage therapy safety, research challenges, how to address identified research gaps, and necessary next steps for implementing massage therapy as a viable pain management option are discussed.

    Background Inflammation is an important factor in the pathogenesis of calcific aortic stenosis (AS). We aimed to evaluate the association between an inflammatory marker, neutrophil-to-lymphocyte ratio (NLR) and major adverse cardiovascular events (MACE) in patients with severe calcific AS. Methods A total of 336 patients with isolated severe calcific AS newly diagnosed between 2010 and 2015 were enrolled in this study. Using Cox proportional hazards (PH) regression models, we investigated the prognostic value of NLR adjusted for baseline covariates including logistic European System for Cardiac Operative Risk Evaluation score (EuroSCORE-I) and undergoing aortic valve replacement (AVR). We also evaluated the clinical relevance of NLR risk groups (divided into low, intermediate, high risk) as categorized by NLR cutoff values. MACE was defined as a composite of all-cause mortality, cardiac death and non-fatal myocardial infarction during the follow-up period. Results The inflammatory marker NLR was an independent prognostic factor most significantly associated with MACE [hazard ratio (HR), 1.06; 95% confidence interval (CI), 1.04–1.09; p-value <0.001]. The goodness-of-fit and discriminability of the model including EuroSCORE-I and AVR (loglikelihood difference, 15.49; p-value <0.001; c-index difference, 0.035; p-value = 0.03) were significantly improved when NLR was incorporated into the model. The estimated Kaplan-Meier survival rates at 5 years for the NLR risk groups were 84.6% for the low risk group (NLR ≤ 2), 67.7% for the intermediate risk group (2 < NLR ≤ 9), and 42.6% for the high risk group (NLR > 9), respectively. Conclusion The findings of the present study demonstrate the potential utility of NLR in risk stratification of patients with severe calcific AS. PMID:27548384

    This work aimed to evaluate the use of a four-point glucagon stimulation test of C-peptide effect on glucose utilization in type 1 diabetic patients using a new mathematical model. A group of 32 type 1 diabetic patients and a group of 10 healthy control subjects underwent a four-point glucagon stimulation test with blood sampling at 0, 6, 15 and 30 min after 1 mg glucagon bolus intravenous administration. Pharmacokinetic and pharmacokinetic/pharmacodynamic models of C-peptide effect on glucose utilization versus area under curve (AUC) were used. A two-sample t test and ANOVA with Bonferroni correction were used to test the significance of differences between parameters. A significant difference between control and patient groups regarding the coefficient of whole-body glucose utilization and AUC C-peptide/AUC glucose ratio (p ≪ 0.001 and p = 0.002, respectively) was observed. The high correlation (r = 0.97) between modeled coefficient of whole-body glucose utilization and numerically calculated AUC C-peptide/AUC glucose ratio related to entire cohort indicated the stability of used method. The short-term four-point glucagon stimulation test allows the numerically calculated AUC C-peptide/AUC glucose ratio and/or the coefficient of whole-body glucose utilization calculated from model to be used to diagnostically identify type 1 diabetic patients.

    Background: Persons with spinal cord injury (SCI) living in the community have high health care utilization (HCU). To date, the interrelationships among multiple secondary health conditions (multimorbidity due to comorbidities and complications) that drive HCU and their impact on patient outcomes are unknown. Objective: To determine the association among multimorbidity, HCU, health status, and quality of life. Methods: Community-dwelling persons with traumatic SCI participated in an online/phone SCI Community Survey. Participants were grouped using the 7-item HCU questionnaire (group 1 did not receive needed care and/or rehospitalized; group 2 received needed care but rehospitalized; group 3 received needed care and not rehospitalized). Personal, injury, and environmental factors; multimorbidity (presence/absence of 30 comorbidities/ complications); health status (Short Form-12); and quality of life measures (Life Satisfaction-11 first question and single-item quality of life measure) were collected. Associations among these variables were assessed using multivariate analysis. Results: The 1,137 survey participants were divided into 3 groups: group 1 (n = 292), group 2 (n = 194), and group 3 (n = 650). Group 1 had the greatest number of secondary health conditions (15.14 ± 3.86) followed by group 2 (13.60 ± 4.00) and group 3 (12.00 ± 4.16) (P < .05). Multimorbidity and HCU were significant risk factors for having a lower SF-12 Mental (P < .001) and Physical Component Score (P < .001). They in turn were associated with participants reporting a lower quality of life (P < .001, for both questions). Conclusions: Multimorbidity and HCU are interrelated and associated with lower health status, which in turn is associated with lower quality of life. Future work will include the development of a screening tool to identify persons with SCI at risk of inappropriate HCU (eg, rehospitalization, not able to access care), which should lead to better patient outcomes and cost

    The aim of the study was to assess health-related quality of life (HRQoL) among metastatic soft tissue (mSTS) or bone sarcoma (mBS) patients who had attained a favourable response to chemotherapy. We employed the EORTC QLQ-C30, the 3-item Cancer-Related Symptoms Questionnaire, and the EQ-5D instrument. HRQoL was evaluated overall and by health state in 120 mSTS/mBS patients enrolled in the SABINE study across nine countries in Europe and North America. Utility was estimated from responses to the EQ-5D instrument using UK population-based weights. The mean EQ-5D utility score was 0.69 for the pooled patient sample with little variation across health states. However, patients with progressive disease reported a clinically significant lower utility (0.56). Among disease symptoms, pain and respiratory symptoms are common. This study showed that mSTS/mBS is associated with reduced HRQoL and utility among patients with metastatic disease. PMID:22550425

    Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosome-autosome translocation with a literature review. PMID:26356509

    Individuals differ in thermosensitivity, thermoregulation, and zones of thermoneutrality and thermal comfort. Whereas temperature sensing and -effectuating processes occur in part unconsciously and autonomic, awareness of temperature and thermal preferences can affect thermoregulatory behavior as well. Quantification of trait-like individual differences of thermal preferences and experienced temperature sensitivity and regulation is therefore relevant to obtain a complete understanding of human thermophysiology. Whereas several scales have been developed to assess instantaneous appreciation of heat and cold exposure, a comprehensive scale dedicated to assess subjectively experienced autonomic or behavioral thermoregulatory activity has been lacking so far. We constructed a survey that specifically approaches these domains from a trait-like perspective, sampled 240 volunteers across a wide age range, and analyzed the emergent component structure. Participants were asked to report their thermal experiences, captured in 102 questions, on a 7-point bi-directional Likert scale. In a second set of 32 questions, participants were asked to indicate the relative strength of experiences across different body locations. Principal component analyses extracted 21 meaningful dimensions, which were sensitive to sex-differences and age-related changes. The questions were also assessed in a matched sample of 240 people with probable insomnia to evaluate the sensitivity of these dimensions to detect group differences in a case-control design. The dimensions showed marked mean differences between cases and controls. The survey thus has discriminatory value. It can freely be used by anyone interested in studying individual or group differences in thermosensitivity and thermoregulation. PMID:27227080

    This study examined the association between physical domestic violence (PDV) and reported child maltreatment in a cohort of children at risk for maltreatment. Participants were 219 6- to 7-year-old children and their caregivers. PDV was measured by combining caregivers' self-reports and children's reports, while child maltreatment was based on state Division of Social Services Central Registry records. Among 219 child-caregiver pairs studied, 42 (19.2%) had at least one maltreatment report in the 2 years following the interviews. PDV consistently predicted child maltreatment, with adjusted odds ratios ranging from 2.96 to 3.46. In addition, we investigated interactions between PDV and other predictors of child maltreatment. Among Aid to Families with Dependent Children (AFDC) participants, PDV was highly associated with child maltreatment. However, this pattern was not observed among subjects who did not have AFDC. There is an increased incidence of child maltreatment reports in families experiencing PDV. AFDC participation intensified the probability of child maltreatment in the presence of PDV. Findings also suggest that in households experiencing PDV, social supports may protect children from maltreatment. PMID:15844726

    In 2009, Elena Long created the LGBT+ Physicists website (http://lgbtphysicists.x10hosting.com) as a warehouse for resources useful for sexual and gender minorities working in physics. This resource has grown to include networking resources, lists of LGBT-friendly universities and localities, recommendations for enacting positive change in physics communities, and out-reach to other STEM-oriented LGBT organizations. This has been possible in large part by the dynamic community of LGBT+ physicists and allies looking to make physics more welcoming towards our community. In 2011, Elena used hir position as Member at Large on the executive committee of the Forum of Graduate Student Affairs (FGSA) to conduct a climate survey that included, among other things, the first serious look at LGBT+ demographics in physics. The survey focused particularly on issues of language heard and harassment experienced by physicists and was broken down into categories based on race, physical and mental ability, gender, and sexuality. Furthermore, it examined the outcomes of experienced harassment and the reasons for when harassment was not reported. Due to the nature of the study, overlapping demographics, especially ``multiple minorities,'' were also explored. This talk will give a brief history of the LGBT+ Physicists resource as well as an overview of the FGSA study.

    2011-01-01

    Background We evaluated the validity of the Canadian Triage and Acuity Scale (CTAS) in elderly emergency department (ED) patients. In particular, we examined the sensitivity and specificity of the CTAS for identifying elderly patients who received an immediate life-saving intervention in the ED. Methods We reviewed the medical records of consecutive patients who were 65 years of age or older and presented to a single academic ED within a three-month period. The CTAS triage scores were compared to actual patient course, including disposition, discharge outcome and resource utilization. We calculated the sensitivity and specificity of the CTAS triage for identifying patients who received an immediate intervention. Results Of the 1903 consecutive patients who were ≥ 65 years of age, 113 (5.9%) had a CTAS level of 1, 174 (9.1%) had a CTAS level of 2, 1154 (60.6%) had a CTAS level of 3, 347 (18.2%) had a CTAS level of 4, and 115 (6.0%) had a CTAS level of 5. As a patient's triage score increased, the severity (such as mortality and intensive care unit admission) and resource utilization increased significantly. Ninety-four of the patients received a life-saving intervention within an hour following their arrival to the ED. The CTAS scores for these patients were 1, 2 and 3 for 46, 46 and 2 patients, respectively. The sensitivity and specificity of a CTAS score of ≤ 2 for identifying patients for receiving an immediate intervention were 97.9% and 89.2%, respectively. Conclusions The CTAS is a triage tool with high validity for elderly patients, and it is an especially useful tool for categorizing severity and for recognizing elderly patients who require immediate life-saving intervention.

    Objective The objective of this study was to describe and analyze the effects of depression on health care utilization and costs in a sample of multimorbid elderly patients. Method This cross-sectional analysis used data of a prospective cohort study, consisting of 1,050 randomly selected multimorbid primary care patients aged 65 to 85 years. Depression was defined as a score of six points or more on the Geriatric Depression Scale (GDS-15). Subjects passed a geriatric assessment, including a questionnaire for health care utilization. The impact of depression on health care costs was analyzed using multiple linear regression models. A societal perspective was adopted. Results Prevalence of depression was 10.7%. Mean total costs per six-month period were €8,144 (95% CI: €6,199-€10,090) in patients with depression as compared to €3,137 (95% CI: €2,735-€3,538; p<0.001) in patients without depression. The positive association between depression and total costs persisted after controlling for socio-economic variables, functional status and level of multimorbidity. In particular, multiple regression analyses showed a significant positive association between depression and pharmaceutical costs. Conclusion Among multimorbid elderly patients, depression was associated with significantly higher health care utilization and costs. The effect of depression on costs was even greater than reported by previous studies conducted in less morbid patients. PMID:24638040

    Patients with non-affective psychotic disorders (NAPD) face higher risk of somatic problems and early natural death compared to the general population. Therefore, treatment guidelines for schizophrenia and psychosis stress the importance of monitoring somatic risk factors. This study examined somatic Health Care utilization (HCu) of patients with NAPD compared to non-psychiatric controls and patients with depression, anxiety or bipolar disorders using a large Health Insurance database. Results show lower specialist somatic HCu of patients with NAPD compared to matched controls and also lower percentages for prescribed somatic medication and general practitioner consultations for patients aged ≥60 years and after longer illness duration.

    Aim To describe practicing physicians’ perceived clinical utility of genome sequencing. Materials & methods We conducted a mixed-methods analysis of data from 18 primary care physicians and cardiologists in a study of the clinical integration of whole-genome sequencing. Physicians underwent brief genomics continuing medical education before completing surveys and semi-structured interviews. Results Physicians described sequencing as currently lacking clinical utility because of its uncertain interpretation and limited impact on clinical decision-making, but they expressed the idea that its clinical integration was inevitable. Potential clinical uses for sequencing included complementing other clinical information, risk stratification, motivating patient behavior change and pharmacogenetics. Conclusion Physicians given genomics continuing medical education use the language of both evidence-based and personalized medicine in describing the utility of genome-wide testing in patient care.

    A descriptive study which explored the types and frequency of contacts experienced by 16 neonates in intensive care environments is reported. Time-sampling methodology, which involved one observation every 20 seconds over a 2-hour period, was utilized. Observations were made during daylight hours, one subject at a time, for a total of 4 subjects in each of the following time periods: 9-11, 11-1, 1-3, and 3-5. Contacts were divided into two categories: direct and indirect. Direct contact included three subcategories: treatment-oriented procedures, activities of daily living, and comforting touch. Direct contacts constituted 63% of all contacts, half of those being treatment-oriented procedures. Activity-of-daily-living and comforting touch contacts comprised 15% and 16% of contacts respectively. Nurses performed the majority of the contacts. PMID:3441146

    Background: Data on the use of emergency medical services (EMS) by patients with cardiac conditions in the Gulf region are scarce, and prior studies have suggested underutilization. Patient perception and knowledge of EMS care is critical to proper utilization of such services. Objectives: To estimate utilization, knowledge, and perceptions of EMS among patients with ST-elevation myocardial infarction (STEMI) in the Emirate of Abu Dhabi. Methods: We conducted a multicenter prospective study of consecutive patients admitted with STEMI in four government-operated hospitals in Abu Dhabi. Semi-structured interviews were conducted with patients to assess the rationale for choosing their prehospital mode of transport and their knowledge of EMS services. Results: Of 587 patients with STEMI (age 51 ± 11 years, male 95%), only 15% presented through EMS, and the remainder came via private transport. Over half of the participants (55%) stated that they did not know the telephone number for EMS. The most common reasons stated for not using EMS were that private transport was quicker (40%) or easier (11%). A small percentage of participants (7%) did not use EMS because they did not think their symptoms were cardiac-related or warranted an EMS call. Stated reasons for not using EMS did not significantly differ by age, gender, or primary language of the patients. Conclusions: EMS care for STEMI is grossly underutilized in Abu Dhabi. Patient knowledge and perceptions may contribute to underutilization, and public education efforts are needed to raise their perception and knowledge of EMS. PMID:27512532

    1985-01-01

    A review was made of failures and irregularities experienced on nickel cadmium batteries for 31 spacecraft. Only rarely did batteries fail completely. In many cases, poorly performing batteries were compensated for by a reduction in loads or by continuing to operate in spite of out-of-voltage conditions. Low discharge voltage was the most common problem observed in flight spacecraft (42%). Spacecraft batteries are often designed to protect against cell shorts, but cell shorts accounted for only 16% of the failures. Other causes of problems were high charge voltage (16%), battery problems caused by other elements of the spacecraft (10%), and open circuit failures (6%). Problems of miscellaneous or unknown causes occurred in 10% of the cases.

    1995-01-01

    Because they are easy to administer, rating scales are often used as proxies for utility measures. The authors investigated the relationship between time-tradeoff utilities and rating scale values in two populations: 124 cancer patients asked to evaluate their current states of health and 102 relatives and close friends of cancer patients asked to evaluate health-state scenarios. None of the models tested effectively described the relationship between individual patients' rating scale values and time-tradeoff utilities for their current states of health. In contrast, both a plateau and a power-function model explained the variability in the responses of the relatives reasonably well (R2 = 0.56 and R2 = 0.58, respectively). Given that many respondents who were unwilling to trade off any time assigned rating scale values of well below 100, a plateau model may represent the best approach to adjusting rating scale values for health-state scenarios when it is not feasible to elicit time-tradeoff utilities.

    Background Low back pain (LBP) is common and associated healthcare costs are significant. While clinical practice guidelines have been established in an attempt to reduce costs and healthcare utilization, it is unclear if adherence to physical therapy guidelines for those with LBP is efficacious. Therefore, the purpose of this study was to assess current evidence and evaluate the impact of physical therapy guideline adherence on subsequent healthcare costs and utilization for patients with LBP. Methods An electronic search was conducted in PubMed, CINAHL (EBSCO Host), AMED (Ovid), and PEDro. Studies included in this review were published in peer reviewed journals and the primary mode of treatment was administered by a physical therapist. Also, the definition of adherence was clearly defined based on claims data and at least one measure of cost or utilization reported. Quality assessment was evaluated via a modified Downs and Black checklist. Due to the conceptual heterogeneity in variable measurements, data were qualitatively synthesized and stratified by reported utilization and cost measures. Results A total of 256 results were identified and after omitting duplicates, 4 articles were retained, which were all retrospective in nature. Quality scores ranged between 19 and 21 points out of a possible 26 on the modified Downs and Black checklist. All identified studies used the same definition of guideline adherence, which focused on billing active codes and minimizing use of passive codes. The results demonstrated trends that, with a few exceptions, suggested those patients with LBP that were treated with an adherent guideline program demonstrated decreased healthcare utilization and an overall healthcare savings. Conclusion Preliminary evidence suggests that adherence to established clinical practice guidelines may assist with decreasing healthcare utilization and costs. Additional research based on prospective randomized controlled trials are needed to provide

    Background As the number of people with Internet access rises, so does the use of the Internet as a potentially valuable source for health information. Insight into patient use of this information and its correlates over time may reveal changes in the digital divide based on patient age and education. Existing research has focused on patient characteristics that predict Internet information use and research on treatment context is rare. Objective This study aims to (1) present data on the proportion of newly diagnosed breast cancer patients treated in German breast centers from 2007 to 2013 who used the Internet for information on their disease, (2) look into correlations between Internet utilization and sociodemographic characteristics and if these change over time, and (3) determine if use of Internet information varies with the hospitals in which the patients were initially treated. Methods Data about utilization of the Internet for breast cancer–specific health information was obtained in a postal survey of breast cancer patients that is conducted annually in Germany with a steady response rate of 87% of consenting patients. Data from the survey were combined with data obtained by hospital personnel (eg, cancer stage and type of surgery). Data from 27,491 patients from 7 consecutive annual surveys were analyzed for this paper using multilevel regression modeling to account for clustering of patients in specific hospitals. Results Breast cancer patients seeking disease-specific information on the Internet increased significantly from 26.96% (853/3164) in 2007 to 37.21% (1485/3991) in 2013. Similar patterns of demographic correlates were found for all 7 cohorts. Older patients (≥70 years) and patients with <10 years of formal education were less likely to use the Internet for information on topics related to their disease. Internet use was significantly higher among privately insured patients and patients living with a partner. Higher cancer stage and a

    To date, no studies have attempted to utilize data from a combination of vital signs, heart rate variability and complexity (HRV, HRC), as well as machine learning (ML), for identifying the need for lifesaving interventions (LSIs) in trauma patients. The objectives of this study were to examine the utility of the above for identifying LSI needs and compare different LSI-associated models, with the hypothesis that an ML model would be superior in performance over multivariate logistic regression models. One hundred four patients transported from the injury scene via helicopter were selected for the study. A wireless vital signs monitor was attached to the patient's arm and used to capture physiologic data, including HRV and HRC. The power of vital sign measurements, HRV, HRC, and Glasgow Coma Scale score (GCS) to identify patients requiring LSIs was estimated using multivariate logistic regression and ML. Receiver operating characteristic (ROC) curves were also obtained. Thirty-two patients underwent 75 LSIs. After logistic regression, ROC curves demonstrated better identification for LSIs using heart rate (HR) and HRC (area under the curve [AUC] of 0.81) than using HR alone (AUC of 0.73). Likewise, ROC curves demonstrated better identification for LSIs using GCS and HRC (AUC of 0.94) than using GCS and HR (AUC of 0.92). Importantly, ROC curves demonstrated that an ML model using HR, GCS, and HRC (AUC of 0.99) had superior performance over multivariate logistic regression models for identifying the need for LSIs in trauma patients. Development of computer decision support systems should utilize vital signs, HRC, and ML in order to achieve more accurate diagnostic capabilities, such as identification of needs for LSIs in trauma patients.

    Many hospital inpatients in South Africa have undiagnosed active and drug-resistant tuberculosis (TB). Early detection of TB is essential to inform immediate infection control actions to minimize transmission risk. We assessed the utility of Xpert® MTB/RIF (GeneXpert) as a screening tool for medical admissions at a large public hospital in South Africa. Consecutive adult patients admitted to medical wards between March-June 2013 were enrolled; sputum specimens were collected and tested by GeneXpert, smear microscopy, and culture. Chest X-rays (CXRs) were conducted as standard care for all patients admitted. We evaluated the proportion of patients identified with TB disease through each diagnostic method. Among enrolled patients whose medical charts were available for review post-discharge, 61 (27%) were diagnosed with TB; 34 (56% of diagnosed TB cases) were GeneXpert positive. When patients in whom TB was identified by other means were excluded, GeneXpert yielded only four additional TB cases. However, GeneXpert identified rifampicin-resistant TB in one patient, who was initially diagnosed based on CXR. The utility of GeneXpert for TB screening was limited in an institution where CXR is conducted routinely and which serves a population in which TB and TB/HIV co-infection are highly prevalent, but it allowed for rapid detection of rifampicin resistance.

    Although researchers have experimentally examined the mechanisms underlying pressure-induced forms of suboptimal performance, or "choking under pressure," there is a lack of research exploring the personal experience of this phenomenon. In an attempt to fill this void in the literature, this study explored experienced golfers' perceptions of the choking experience within a personal construct psychology (Kelly, 1955/1991) framework. Both male and female golfers participated in either a focus group (n = 12; all males) or one-on-one interview (n = 10; female = 7, male = 3) using experience cycle methodology (Oades & Viney, 2000) to describe their perceptions of the choking experience. Discussions were transcribed verbatim and subsequently analyzed using grounded theory analytical techniques (Strauss & Corbin, 1998). Analyses revealed five central categories representing the personal experience of choking under pressure: antecedents, personal investment, choking event, consequences, and learning experiences. The findings reported here suggest that the choking phenomenon, which can involve acute or chronic bouts of suboptimal performance (relative to the performance expectations of the athlete), is a complex process involving the interplay of several cognitive, attentional, emotional, and situational factors. Implications of the findings for a construct definition of choking are discussed, and several applied considerations are offered. PMID:20167952

    The inhibition of a prepotent response is an essential executive function which enables us to suppress inappropriate actions in a given context. Individuals with fencing expertise exhibit behavioral advantages on tasks with high demands on response inhibition. This study examines the electrophysiological basis for the superior response inhibition in experienced fencers. In the Go/Nogo task where frequent stimuli required a motor response while reaction had to be withheld to rare stimuli, the fencers, compared with the non-fencers, exhibited behavioral as well as electrophysiological advantages when suppressing prepotent responses. The superior response inhibition in the fencers was characterized by enhanced Nogo-N2 and reduced Nogo-P3. Single-trial analysis revealed that the amplitude difference of the Nogo-N2 between two groups was caused by lower single-trial latency variability in the fencers (may be due to low attentional fluctuation and/or stable neural processing speed) while the amplitude difference of the Nogo-P3 resulted from truly weaker neural activity in the fencers (may be because few cognitive sources are needed and few control efforts are made). The two inhibition-related components are distinct neurophysiological indexes that, on the one hand, provide effective guidance to titrate the level of executive function in fencers, and on the other hand, facilitate to monitor fencers’ improvement in the training process.

    The purpose of the research was to study influence of first diagnosed type 1 diabetes mellitus (FDDM-1), including metabolic consequences of diabetic ketoacidosis, on utilization of main nutritious substrates under conditions of aerobic exercise. 48 patients with FDDM-1 (15females and 33 males) and 36 healthy volunteers, composing the control group, had a protocol of bicycle ergometry test with slowly growing load. Patients with FDDM-1 were divided into 2 subgroups in line with clinical characteristic of endocrinopathy debut. Subgroup 1 consisted of 15 patients, who had diabetic precoma, subgroup 2 was composed of 33 patients who did not have diabetic ketoacidosis in onset of disease. Aerobic load in patients with FDDM-1 was realized in stable condition of the main disease subcompensation, and in 1 month under condition of FDDM-1 compensation. Lipid and carbohydrate consumption percentage was estimated by the method of indirect colorimetry. Patients with FDDM-1 in stage of subcompensation did not have metabolism transformation with dominating consumption of lipids, which was noticed in healthy persons. When increase intensity of physical exercise, the reliably higher rate of carbohydrate sources consumption for supply of muscular contractions was noticed in patients with FDDM-1, especially in subgroup 2. After FDDM-1 compensation the structure of metabolic substrates consumption in warm-up period in both subgroups of patients with FDDM-1 did not have reliable differences in comparison with control group, but all further levels of aerobic exercise were characterized by significant increase of carbohydrate sources oxidation in comparison with such oxidation in healthy persons. Patients with FDDM-1 had decreased muscular tissue ability to utilize lipids in the aerobic stage of physical exercise, which can cause decrease of tolerance to physical work as a result of disorder lipid and carbohydrate participation in motion activity.

    Background Heart failure patients with implantable defibrillators place a significant burden on health care systems. Remote monitoring allows assessment of device function and heart failure parameters, and may represent a safe, effective, and cost-saving method compared to conventional in-office follow-up. Objective We hypothesized that remote device monitoring represents a cost-effective approach. This paper summarizes the economic evaluation of the Evolution of Management Strategies of Heart Failure Patients With Implantable Defibrillators (EVOLVO) study, a multicenter clinical trial aimed at measuring the benefits of remote monitoring for heart failure patients with implantable defibrillators. Methods Two hundred patients implanted with a wireless transmission–enabled implantable defibrillator were randomized to receive either remote monitoring or the conventional method of in-person evaluations. Patients were followed for 16 months with a protocol of scheduled in-office and remote follow-ups. The economic evaluation of the intervention was conducted from the perspectives of the health care system and the patient. A cost-utility analysis was performed to measure whether the intervention was cost-effective in terms of cost per quality-adjusted life year (QALY) gained. Results Overall, remote monitoring did not show significant annual cost savings for the health care system (€1962.78 versus €2130.01; P=.80). There was a significant reduction of the annual cost for the patients in the remote arm in comparison to the standard arm (€291.36 versus €381.34; P=.01). Cost-utility analysis was performed for 180 patients for whom QALYs were available. The patients in the remote arm gained 0.065 QALYs more than those in the standard arm over 16 months, with a cost savings of €888.10 per patient. Results from the cost-utility analysis of the EVOLVO study show that remote monitoring is a cost-effective and dominant solution. Conclusions Remote management of heart

    Objective: To investigate the relationship between the characteristics of somatic symptoms and depression severity, quality of life (QOL), and health resources utilization in patients with major depressive disorder (MDD) in primary care setting. Method: This cross-sectional, nationwide epidemiologic study, carried out in 1150 primary care patients with DSM-IV–defined MDD, evaluated the characteristics of somatic symptoms by means of the Standardized Polyvalent Psychiatric Interview. Depression severity and QOL were evaluated by means of the Zung Self-Rating Depression Scale (SDS) and the Physical and Mental Component Summaries of the Medical Outcomes Study 12-item Short-Form Health Survey. Health resources utilization was measured in terms of doctor consultations and hospitalizations. The associations were assessed by means of adjusted analyses. The study was carried out from April 2004 to July 2004. Results: Disability associated with somatic symptoms and number of somatic symptoms were strongly associated with increased depression severity (2.45 and 0.29 increase in SDS score, respectively) and health resources utilization (odds ratios of 1.42 and 1.04, respectively). Associated disability, frequency, and persistence during leisure time of somatic symptoms were strongly associated with poorer QOL. In contrast, we found a weaker relationship between duration and intensity of somatic symptoms and depression severity, QOL, and health resources utilization. Conclusions: Of the studied somatic symptom characteristics, somatic symptom–associated disability and number of somatic symptoms are strongly associated with increased depression severity and health resources utilization, as well as with decreased QOL. Our results may help physicians identify relevant characteristics of somatic symptoms to more effectively diagnose and treat depression in primary care patients. PMID:19158973

    Here we report our success in performing lateral approach tracheal intubation in a patient with severe respiratory failure due to septic shock caused by shoulder joint abscess. A 71-year-old woman presented with severe respiratory difficulty due to sepsis from a shoulder joint abscess and was scheduled for emergent drainage and irrigation. She could not breathe sufficiently in the supine position and thus maintained a semi-sitting position. She was also unable to move from the ward bed to the operating table due to severe shoulder pain. We induced anesthesia in a semi-sitting position in the ward bed. Mask ventilation was performed using the two-hand technique from the lateral approach. Tracheal intubation was also performed with a left lateral approach utilizing the Pentax-AWS Airwayscope (AWS). Lateral approach for tracheal intubation utilizing AWS may be useful in patients who present with severe respiratory difficulty. PMID:26422963

    This report describes an ongoing Phase I clinical trial testing the safety of adoptive cell therapy (ACT) using autologous tumor-infiltrating lymphocytes (TIL) in patients with primary hepatocellular carcinoma (HCC). Fifteen HCC patients were treated with their activated and expanded TILs following tumor resection. From a total of 17 patients with HCC, TIL were successfully expanded from 15 patients (88%), whereas two patients showed minimal or no expansion of TIL. Transient increase in the frequency of T cells was observed after adoptive transfer who was found only associated with grade I flu-like symptoms and malaise. After a median follow-up of 14 months, 15 patients (100%) were alive; and 12 patients (80%) showed no evidence of disease, 3 patients (patient 1,11,12) had tumor recurrence. The time to the diagnosis of tumor recurrence following therapy ranged from 105 to 261 days. These results indicate that immunotherapy with activated and expanded autologous TIL could be successfully performed with low toxicity, thus would serve as a novel treatment modality for patients with HCC.

    Purpose The use of abdominal computed tomography (ACT) utilization is increasing to a remarkable extent in the pediatric Emergency Department (ED), but the clinical benefit of increased use of ACT for pediatric surgical patients remains uncertain. Methods A retrospective review was conducted to investigate if, for patients who had visited pediatric ED during the last 5 years, increasing utilization of ACT would increase the detection rate of acute appendicitis, increase the detection rate of surgical conditions other than appendicitis, and decrease the hospital admission rate for surgical conditions. Results During the study period, there were 37,918 ED visits; of these, 3,274 (8.6%) were for abdominal pain, 844 (2.2%) had ACT performed. The annual proportional increase of the ACT was statistically significant (1.56% to 2.46%, P = 0.00), but the detection rate of acute appendicitis (3.3% to 5.1%) or other surgical conditions (1.7% to 2.8%) showed no statistically significant changes. Hospital admission rates (5.6% to 6.8%) also showed no significant changes during the study period. Conclusion Increasing utilization of ACT does not lead to the improved outcomes in caring for pediatric surgical patients visiting the pediatric ED. Careful evaluation for the indication for ACT is needed in the pediatric ED. PMID:25368849

    Glycated hemoglobin (HbA1c) is an approved and widely used laboratory investigation for diagnosis of diabetes that is not affected by acute changes in blood glucose. Our aim was to analyze the extent to which routine HbA1c measurements diagnose unknown diabetes mellitus (DM) in patients presenting with ST-segment elevation myocardial infarction (STEMI). We also compared outcomes in patients with newly diagnosed DM, previously established DM and those without DM. Consecutive patients undergoing PCI for STEMI from January 2005 to December 2012 were included and routinely performed admission HbA1c was used to identify patients with previously undiagnosed DM (HbA1c ≥6.5 and no history of DM or DM therapy) and pre-DM (HbA1c 5.7% to 6.4%). Overall 1,686 consecutive patients underwent primary percutaneous coronary intervention for STEMI during the study period and follow-up data were available for 1,566 patients (90%). A quarter of the patients (24%, n = 405) had history of DM, 7% (n = 118) had previously undiagnosed DM, and 38.7% (n = 652) had pre-DM. Mortality was comparable in patients with known DM and newly diagnosed DM both in-hospital (11.1% vs 11.9%, p = 0.87) and at 3-year follow-up (27.3% and 24%). Patients with DM, including those who were newly diagnosed, had higher mortality at 3 years (26.5%) compared to those with pre-DM (12.1%) or no dysglycemia (11.2%, p <0.01). In conclusion, a substantial number of patients with STEMI have previously undiagnosed DM (7%). These patients have similar in-hospital and long-term mortality as those with known DM, and outcomes are inferior to patients without dysglycemia. PMID:26768673

    Background. The aim of this study was to monitor oropharyngeal bacterial colonization in patients indicated for percutaneous endoscopic gastronomy (PEG). Methods. Oropharyngeal swabs were obtained from patients prior to PEG placement. A development of peristomal infection was evaluated. The analysis of oropharyngeal and peristomal site pathogens was done. Results. Consecutive 274 patients referred for PEG due to neurological disorder or cancer completed the study. Oropharyngeal colonization with pathogens was observed in 69% (190/274), dominantly in the neurologic subgroup of patients (P < 0.001). Peristomal infection occurred in 30 (10.9%) of patients and in 57% of them the correlation between oropharyngeal and peristomal agents was present. The presence of oropharyngeal pathogens was assessed as an important risk factor for the development of peristomal infection only in oncological patients (OR = 8.33, 95% CI: 1.66–41.76). Despite a high prevalence of pathogens in neurological patients, it did not influence the risk of peristomal infection with the exception for methicillin resistant Staphylococcus aureus (MRSA) carriers (OR 4.5, 95% CI: 1.08–18.76). Conclusion. During oropharyngeal microbial screening prior to the PEG insertion, the detection of pathogens may be a marker of the increased risk of peristomal infection in cancer patients only. In neurological patients the benefit of the screening is limited to the detection of MRSA carriers. PMID:25243153

    A high-flow nasal cannula (HFNC) is a newly developed device that enables high-flow oxygen therapy for patients with serious cardiopulmonary problems, but there are few data regarding its use in patients with hematological disease. The efficacy and tolerability of HFNCs for patients who developed ARF during the treatment of various hematological diseases was evaluated. Fifty-six patients underwent HFNC therapy during the last 2 years, and the causes of ARF were mainly pneumonia (n = 37) or acute congestive heart failure (n = 7). Only 11 patients (20 %) showed a good response to HFNC therapy, and remaining 45 patients (80 %) failed to respond to the initial HFNC therapy and, therefore, underwent second-line therapy including endotracheal intubation with mechanical ventilation (n = 15), non-invasive positive pressure ventilation (n = 1), or narcotic palliation alone (n = 29). Thus, HFNC appear not to be a viable treatment option in 4 out of 5 patients in this cohort of patients with hematological disease, but it was well tolerated in most patients (96 %); no major complications except for nasal soreness (n = 2) were observed. Multivariate analysis showed that the cause of ARF (pneumonia, odds ratio 11.2, 95 % CI 1.76-71.5, p = 0.01) was the only risk factor for treatment failure. PMID:27186476

    Objective The purpose of this study was to determine the cost-utility of treating anemic dialysis patients with continuous erythropoietin receptor activator (CERA) once monthly or Epoetin Beta (EpoB) thrice weekly compared with a reference strategy of managing anemia with red blood cell transfusion (RBCT). Methods Cost-utility analysis study design. Decision analysis model, National health care payer, over 1 year with the publicly funded health care system. Chronic hemodialysis patients with renal anemia were included. The outcome marker of this study was the incremental cost per quality-adjusted life-year (QALY) gained (incremental cost-utility ratio [ICUR]) of CERA or EpoB relative to RBCT. Results The total cost per patient (in US$) was estimated at $2,176.37, $4,107.01, and $4,356.69 for RBCT, CERA, and EpoB, respectively. The cost-utility ratio was calculated at 4,423.52, 6,955.50, and 7,406.38 $/QALY for RBCT, CERA, and EpoB, with an ICUR of CERA and EpoB in relation to RBCT at 19,606.40 and 22,466.09 $/QALY, respectively. In sensitivity analysis, the model was most sensitive to hospitalization costs, hospital stay, and annual number of RBCT units. Also, assuming utility and survival improvement with erythropoiesis stimulating agents use resulted in a decrease in ICUR at 13,429 $/QALY for CERA and 15,331 $/QALY for EpoB. In probabilistic sensitivity analysis, the main results of our model were unchanged; CERA and EpoB were more costly and more effective than RBCT below a threshold of 19,500 $/QALY. CERA was the best option for a willingness to pay over 19,500 $/QALY. Limitations Some model parameters were obtained from observational data, the comparator RBCT is not the standard of care. Conclusion Our study suggests that managing anemia in dialysis patients with CERA or EpoB may result in better outcomes with higher overall costs. Considering different assumptions, we found substantial variability in the estimates of the cost-utility and incremental of using

However, factors including efficacy, tolerability, ease of use, and cost burden may affect ustekinumab utilization. Noncompliance may, in turn, affect treatment response. Objective To evaluate ustekinumab utilization in the real-world setting in Asia-Pacific countries. Methods In this phase 4 observational study conducted in Indonesia, Malaysia, Singapore, Korea, and Taiwan, adults with plaque psoriasis receiving ustekinumab were followed for up to 52 weeks. Study endpoints were the proportion of all patients using ustekinumab according to label-recommended intervals and the proportion of Korean patients who achieved a psoriasis area severity index 75 response at week 16. Safety was assessed by monitoring adverse events. Results Overall, 169 patients received ustekinumab (Korea, n=102; other countries, n=67). Just over half (56.2%) of patients used ustekinumab with the label-recommended interval from baseline to week 40; the proportion was higher in Korea (73.5%) than in other countries (29.9%), probably because ustekinumab was provided without charge for Korean patients up to week 40. Noncompliance increased after week 40 in Korea and from week 28 in other Asia-Pacific countries, with cost cited as the most common reason. At week 16, 56.9% of Korean patients achieved a Psoriasis Area Severity Index 75 response. Safety results were in line with those seen in previous studies. Conclusion More than half of all patients in Asia-Pacific countries used ustekinumab as per the label-recommended dose interval, but reimbursement variations between countries may have confounded overall results.

    Background: Chemotherapy for lymph nodes cancer is often composed of several drugs that are used in a treatment program. Objectives: The aim of this study was to perform a cost-utility analysis of IEV regimen (ifosfamide, epirubicin and etoposide) versus ESHAP regimen (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin) in patients with lymphoma in the south of Iran. Patients and Methods: This was a cost-utility analysis done as a cross-sectional study in the south of Iran. Using decision tree, expected costs, quality -adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER) were estimated. In addition, the robustness of results was examined by sensitivity analysis. Results: The results of this study indicated that the total lymphoma patients were about 65 people that 27 patients received IEV regimen and 38 patients ESHAP (43 patients with Hodgkin’s and 22 with non-Hodgkin lymphoma). The results of decision tree showed that in the IEV arm, the expected cost was $20952.93 and the expected QALYs was 3.89 and in the ESHAP arm, the expected cost was $31691.74 and the expected QALYs was 3.86. Based on the results of the study, IEV regimen was cost-effective alternative to the ESHAP regimen. Conclusions: According to the results of this study, it is recommended that oncologists use IEV instead of ESHAP in the treatment of patients with lymphoma and because of high costs of IEV drug costs, it is suggested that IEV drugs should be covered by insurance.

    Multiple sclerosis (MS) is a demyelinating disease in the central nervous system. Genetics have been considered as a leading factor in the prevalence and disease course of MS. We have presented an informatics-based eFolder system for integrating patients' clinical data with MR images and lesion quantification results. The completed eFolder system has been designed and developed in aiding to evaluate disease manifestation differences in Hispanic and Caucasian MS patients. MS lesion data, as shown in MRI, can be extracted by the 3-D automatic lesion detection tool in the eFolder, and data storing and mining tools in eFolder is able to extract and compare data from individual patients. The computer-aided detection (CAD) algorithm has been modified and enhanced to include spatial information as detection criteria. For this study, 36 Caucasian MS patients and 36 matched Hispanic patients have been selected. Most recent MR images of the patients are collected, and images are evaluated both by the CAD tool in the eFolder and radiologists. The results are compared between Caucasian and Hispanic patients and statistically evaluated to see if the two populations have significant difference in lesion presentations. The results can be used to evaluate differences in the two groups of patients and to evaluate the new CAD algorithm's performance with radiologists' contours. Significant findings can further evaluate effectiveness of MS eFolder in MS-related research.

    At many institutions, it is common practice for trauma patients with traumatic intracranial hemorrhage (ICH) to receive routine repeat head computed tomographic (CT) scans after the initial CT scan, regardless of symptoms, to evaluate progression of the injury. The purpose of this study was to assess quantifiable risk factors (age, anticoagulation, gender) that could place patients at greater risk for progression of injury, thus requiring surgical intervention (craniotomy, craniectomy) for which serial CT scanning would be useful. From January 2014 to June 2015, a total of 211 patients presented with traumatic ICH and 198 were eligible for inclusion. Twenty-six patients required operative intervention for ICH. One of 26 patients went to the operating room as a result of repeat head CT scans without associated mental status change, change in neurological examination, or associated symptoms such as nausea or vomiting. Significant changes in patient management due to routine repeat CT scans were not observed. There were no statistically significant risk factors identified to place patients at higher risk for progression of disease. The data from this analysis emphasized the importance of nursing care in identifying and relaying changes in patient condition to the trauma team. PMID:27618379

    AIM: To study clinical and histopathological features of nonalcoholic fatty liver disease (NAFLD) in patients with and without type 2 diabetes mellitus (T2DM) using updated nonalcoholic steatohepatitis clinical research network (NASH-CRN) grading system. METHODS: We retrospectively analyzed data of 235 patients with biopsy proven NAFLD with and without T2DM. This database was utilized in the previously published study comparing ethnicity outcomes in NAFLD by the same corresponding author. The pathology database from University of Chicago was utilized for enrolling consecutive patients who met the criteria for NAFLD and their detailed clinical and histopathology findings were obtained for comparison. The relevant clinical profile of patients was collected from the Electronic Medical Records around the time of liver biopsy and the histology was read by a single well-trained histopathologist. The updated criteria for type 2 diabetes have been utilized for analysis. Background data of patients with NASH and NAFLD has been included. The mean differences were compared using χ2 and t-test along with regression analysis to evaluate the predictors of NASH and advanced fibrosis. RESULTS: Patients with NAFLD and T2DM were significantly older (49.9 vs 43.0, P < 0.01), predominantly female (71.4 vs 56.3, P < 0.02), had higher rate of metabolic syndrome (88.7 vs 36.4, P < 0.01), had significantly higher aspartate transaminase (AST)/alanine transaminase (ALT) ratio (0.94 vs 0.78, P < 0.01) and Fib-4 index (1.65 vs 1.06, P < 0.01) as markers of NASH, showed higher mean NAFLD activity score (3.5 vs 3.0, P = 0.03) and higher mean fibrosis score (1.2 vs 0.52, P < 0.01) compared to patients with NAFLD without T2DM. Furthermore, advanced fibrosis (32.5 vs 12.0, P < 0.01) and ballooning (27.3 vs 13.3, P < 0.01) was significantly higher among patients with NAFLD and T2DM compared to patients with NAFLD without T2DM. On multivariate analysis, T2DM was independently associated with NASH

    The launch of Internet-based remote monitoring is an important milestone in the management of patients with cardiac rhythm management (CRM) devices. A remote monitoring system consists of a portable patient monitor, a central database in a secure server, and a password-protected website, where clinicians can view and analyse patient's device data. The latest CRM devices support automatic wireless data transmission from the device to the patient monitor, making the system even more user-friendly. In Finland the longest experience with remote monitoring of cardiac rhythm management devices is in the Oulu University Hospital. According to our experience remote monitoring provides a tremendous convenience for patients and clinicians and reduces the cost of follow-up. PMID:19938409

    Background Studies demonstrate an increase in radiation exposure with transradial approach (TRA) when compared with transfemoral approach (TFA) for coronary angiography. Given the learning curve associated with TRA, it is not known if this increased radiation exposure to patients is seen when procedures are performed by experienced operators. Methods We retrospectively evaluated 1,696 patients who underwent coronary angiography with or without percutaneous coronary intervention (PCI) by experienced operators at a tertiary center from October 2010 to June 2011. Experienced operators were defined as those that perform >75 PCIs/year with >95% of cases performed using the TRA or TFA approach for ≥5 years. The outcomes of interest were dose area product (DAP) and fluoroscopy time (FT). Results Of the 1,696 patients, 1,382 (81.5%) were performed by experienced femoral operators using TFA and 314 (18.5%) were performed by experienced radial operators using TRA. Most of these cases (65.4%) were diagnostic only (870 TFA and 240 TRA) with both DAP (6040 [3210–8786] vs 5019 [3377–6869] μGy·m2, P = .003] and FT [6.2 [4.0–10.3] vs 3.3 [2.6–5.0] minutes, P < .001) significantly higher using TRA versus TFA. For procedures involving PCI, despite similar baseline patient, procedural and lesion characteristics, DAP and FT remained significantly higher using TRA versus TFA (19,649 [11,996–25,929] vs 15,395 [10,078–21,617] μGy·m2, P = .02 and 22.1 [13.3–31.0] vs. 13.8 [9.8–20.3] minutes, P < .001). Conclusions In a contemporary cohort of patients undergoing coronary angiography by experienced operators, TRA was associated with higher radiation exposure when compared with TFA. PMID:23453094

    Background Maintenance of a well-functioning vascular access and minimal needling pain are important goals for achieving adequate dialysis and improving the quality of life in hemodialysis (HD) patients. Far-infrared (FIR) therapy may improve endothelial function and increase access blood flow (Qa) and patency in HD patients. The aim of this study was to evaluate effects of FIR therapy on Qa and patency, and needling pain in HD patients. Methods This prospective clinical trial enrolled 25 outpatients who maintained HD with arteriovenous fistula. The other 25 patients were matched as control with age, sex, and diabetes. FIR therapy was administered for 40 minutes during HD 3 times/wk and continued for 12 months. The Qa was measured by the ultrasound dilution method, whereas pain was measured by a numeric rating scale at baseline, then once per month. Results One patient was transferred to another facility, and 7 patients stopped FIR therapy because of an increased body temperature and discomfort. FIR therapy improved the needling pain score from 4 to 2 after 1 year. FIR therapy increased the Qa by 3 months and maintained this change until 1 year, whereas control patients showed the decrease in Qa. The 1-year unassisted patency with FIR therapy was not significantly different from control. Conclusion FIR therapy improved needling pain. Although FIR therapy improved Qa, the unassisted patency was not different compared with the control. A larger and multicenter study is needed to evaluate the effect of FIR therapy. PMID:27069856

    Background Severe anemia is a common side effect of Pegylated Interferon + Ribavirin (PR) and Telaprevir (TVR) in hepatitis C virus (HCV) genotype 1 patients with advanced fibrosis or cirrhosis (F3–F4). Inosine triphosphatase (ITPA) genetic variants are associated with RBV- induced anemia and dose reduction. Aim To test the association of ITPA polymorphisms rs1127354 and rs7270101 with hemoglobin (Hb) decline, need for RBV dose reduction (RBV DR), erythropoietin (EPO) support and blood transfusions during the first 12 weeks of TVR triple therapy. Materials and Methods 69 consecutive HCV-1 patients (mean age 57 years) with F3-F4 who received PR and TVR were genotyped for ITPA polymorphisms rs1127354 and rs7270101. Estimated ITPA deficiency was graded on severity (0–3, no deficiency/mild/moderate/severe). Results ITPA deficiency was absent in 48 patients (70%), mild in 12 (17%) and moderate in 9 patients (13%). Mean week 4 Hb decline was higher in non ITPA deficient patients (3,85 g/dL) than in mildly or moderately ITPA deficient patients (3,07 g/dL and 1,67 g/dL, p<0.0001). Grade 3–4 anemia developed in 81% non ITPA deficient patients versus 67% mild deficient and 55% moderate deficient patients (p = ns). Grade of ITPA deficiency was not associated with RbvDR (no deficiency: 60%, mild: 58%, moderate: 67%; p = ns), EPO use (no deficiency: 65%, mild: 58%, moderate:56%; p = ns) or need for blood transfusion (no deficiency: 27%, mild: 17%, moderate: 33%; p = ns). Conclusions In patients with F3–F4 chronic hepatitis C receiving TVR based therapy, ITPA genotype does not impact on the management of early anemia. PMID:24760000

    Many poisoned patients may only require a period of observation after their exposure. There are limited data describing the use of observation units for managing poisoned adult and pediatric patients. We performed a retrospective review of all patients reported to the ToxIC Case Registry between January 1, 2012 and December 31, 2013. Eligible patients included those who received a bedside consultation by a medical toxicologist and whose care was provided in an observation unit, or those who were admitted under the care of a medical toxicologist in an observation unit. A total of 15,562 poisonings were reported to the registry during the study period, of which 340 (2.2 %) involved patients who were cared for in an observation unit. Of these patients, 22.1 % were 18 years of age or younger, and the remaining 77.9 % were greater than 18 years of age. The most common reason for exposure was the intentional ingestion of a pharmaceutical agent in both adult (30.2 %) and pediatric patients (36.0 %). Alcohols (ethanol) (24.9 %), opioids (20.0 %), and sedative-hypnotics (17.7 %) were the most common agent classes involved in adult patient exposures. The most common agent classes involved in pediatric exposures were antidepressants (12.0 %), anticonvulsants (10.7 %), and envenomations (10.7 %). In adult patients, the most common signs and symptoms involved the nervous system (52.0 %), a toxidrome (17.0 %), or a major vital sign abnormality (14.7 %). In pediatric patients, the most common signs and symptoms involved the nervous system (53.3 %), a toxidrome (21.3 %), or a major vital sign abnormality (17.3 %). The results of this study demonstrate that a wide variety of poisoned patients have been cared for in an observation unit in consultation with a board-certified medical toxicologist. Patterns for the reasons for exposure, agents responsible for the exposure, and toxicological treatments will continue to evolve. Further study is needed to identify

    The performance of the Fungitell assay was investigated in 100 patients with haematological malignancy undergoing chemotherapy who developed antibiotic-unresponsive neutropenic fever (AUNF). Serum beta-D-glucan (BG) concentrations were significantly elevated on the first day of AUNF and all subsequent alternate days to day 10 in 38 patients who developed an invasive fungal infection (IFI) compared to 42 patients remaining free of such infections. The mean and median values of BG were 171.9+/-29.6 and 95.8 pg ml(-1), respectively, for patients with IFI and 64.4+/-17.1 and 32.9 pg ml(-1) for patients with only AUNF (P<0.0001). The differences remained significant over the 10 days despite antifungal therapy. The occurrence of > or =2 sequential concentrations of > or =80 pg ml(-1) ('positive' test) was found to give the best overall option for diagnosis, with an accuracy of 81.3%, sensitivity of 86.8%, positive predictive value of 76.7% and negative predictive value of 86.5%. Of the patients with an IFI, 78% developed a positive test at or before the clinical diagnosis was made -- this occurred at a mean (range) of 1.25 (-14 to +14) days prior to the IFI diagnosis. By starting sampling of blood from the first day of neutropenia rather than from the first day of AUNF, 50% of the patients with subsequent IFI would have been identified 5 days earlier. Increasing sampling to daily from alternate-day frequency did not further improve this earlier timing of an IFI diagnosis. A greater proportion of patients with persistent high levels of BG without overt IFI had severe enterocyte damage or mucositis than those with lower levels of BG without IFI (P=0.002). If the results of the initial BG test had been acted on to change antifungal therapy, discontinuation would have been inappropriate in 30% of patients and would have delayed definitive antifungal therapy. Although the findings for the cohort of patients studied are very useful, there is inter-patient variability in the

    The lifetime utility of liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) is still controversial. The aim of this study was to ascertain when LT is cost-effective for HCC patients, with a view to proposing new transplant selection criteria. The study involved a real cohort of potentially transplantable Italian HCC patients (n = 2419 selected from the Italian Liver Cancer group database) who received nontransplant therapies. A non-LT survival analysis was conducted, the direct costs of therapies were calculated, and a Markov model was used to compute the cost utility of LT over non-LT therapies in Italian and US cost scenarios. Post-LT survival was calculated using the alpha-fetoprotein (AFP) model on the basis of AFP values and radiological size and number of nodules. The primary endpoint was the net health benefit (NHB), defined as LT survival benefit in quality-adjusted life years minus incremental costs (US $)/willingness to pay. The calculated median cost of non-LT therapies per patient was US $53,042 in Italy and US $62,827 in the United States. On Monte Carlo simulation, the NHB of LT was always positive for AFP model values ≤ 3 and always negative for values > 7 in both countries. A multivariate model showed that nontumor variables (patient's age, Child-Turcotte-Pugh [CTP] class, and alternative therapies) had the potential to shift the AFP model threshold of LT cost-ineffectiveness from 3 to 7. LT proved always cost-effective for HCC patients with AFP model values ≤ 3, whereas the cost-ineffectiveness threshold ranged between 3 and 7 using nontumor variables. PMID:26183802

    Plasma and buffy-coat vitamin C were estimated in 158 samples from 139 lung-cancer patients, at all stages of the disease. Most samples showed hypovitaminosis C in both estimations: 64% had plasma, and 25% buffy-coat values below the thresholds for incipient clinical scurvy (0.3 mg% and 10 micrograms/10(8) cells respectively). Levels were diet-dependent and could be increased by oral supplements. Levels were low both in tumour-bearing patients and in those clinically free of disease after resection. The latter had particularly low values during the first 6 months, indicating the utilization of vitamin C in surgical repair. The vitamin C content of 13 primary lung tumours was assayed: tumours had a higher vitamin C content (mean 111.6 +/- 55.1 micrograms/g tissue) than normal lung (58.5 +/- 20.4 micrograms/g). Mononuclear cells from normal individuals show a higher vitamin C content than polymorphs, but in lung-cancer patients the expected correlation of buffy-coat vitamin C with the proportion of lymphocytes in peripheral blood was obscured by an inverse correlation in patients with relative lymphocytosis (greater than or equal to 25% lymphocytes), confirmed by an inverse correlation of the proportion of lymphocytes in peripheral blood with mononuclear-cell vitamin C in 14 patients in whom this was measured. These correlations were unaffected by controlling for plasma values, and indicate the utilization of vitamin C in lymphocyte-related anti-tumour mechanisms. Vitamin C is necessary for phagocytosis and for the expression of cell-mediated immunity. In view of the increasing circumstantial evidence that immune mechanisms exert some measure of control on tumour extension and metastasis in man, the effect of supplementation with vitamin C in lung-cancer patients on survival should be tested in a clinical trial.

    ABSTRACT Chromosomal DNA is a constant source of information, essential for any given cell to respond and adapt to changing conditions. Here, we investigated the fate of exponentially growing bacterial cells experiencing a sudden and rapid loss of their entire chromosome. Utilizing Bacillus subtilis cells harboring an inducible copy of the endogenous toxin yqcG, which encodes an endonuclease, we induced the formation of a population of cells that lost their genetic information simultaneously. Surprisingly, these DNA-less cells, termed DLCs, did not lyse immediately and exhibited normal cellular morphology for a period of at least 5 h after DNA loss. This cellular integrity was manifested by their capacity to maintain an intact membrane and membrane potential and cell wall architecture similar to those of wild-type cells. Unlike growing cells that exhibit a dynamic profile of macromolecules, DLCs displayed steady protein and RNA reservoirs. Remarkably, following DLCs by time lapse microscopy revealed that they succeeded in synthesizing proteins, elongating, and dividing, apparently forming de novo Z rings at the midcell position. Taken together, the persistence of key cellular events in DLCs indicates that the information to carry out lengthy processes is harbored within the remaining molecular components. PMID:25922388

    Background and Aims. The role of capsule endoscopy (CE) in the <50 years of age patients with iron deficiency anaemia (IDA) remains unclear. We aim to assess its utility in this cohort. Methods. All patients referred for CE for recurrent IDA were included retrospectively. Patients were divided into Group 1 (<50 years) and Group 2 (≥50 years). Results. There were 971 patients with recurrent IDA and 28% belonged to Group 1. The mean age was 40 years in this group with a DY of 28% (n = 76). Significant diagnoses included erosions and ulcers (26%; n = 71), small bowel (SB) angioectasia (AE) (10%; n = 27), SB tumours (3%; n = 7), Crohn's disease (3%; n = 7), SB bowel strictures (1%; n = 3), and SB varices (1%; n = 2). On logistic regression, the presence of diabetes (P = 0.02) and the use of warfarin (P = 0.049) was associated with increased DY. The DY in Group 2 was 38% which was significantly higher than in Group 1 (P = 0.02). While SB tumours were equally common in both groups, AE was commoner in Group 2 (P < 0.001). Conclusion. A significant proportion of patients <50 years are referred for CE. Although the DY is lower compared to those ≥50 years, significant pathology is found in this age group. CE is advisable in patients <50 years old with recurrent IDA and negative bidirectional endoscopies. PMID:25922603

    Pulmonary Langerhans cell histiocytosis (PLCH) is a rare disease that occurs almost exclusively in smokers, generally young adults between 20 and 40 years old. Prognostic biomarkers of the disease are lacking. This study describes the clinical-radiological features of a group of PLCH patients and applies a semi-quantitative CT score of the chest to verify the prognostic value of radiological findings in this disease. Clinical-radiological and immunological data from 12 Caucasian patients (6M, 7 smokers and 5 ex-smokers, mean age 36±8 years) were recorded at onset and after a follow-up period of 4 years. Application of the semi-quantitative CT score revealed a prevalently cystic pattern at onset and follow-up in the majority of the patients. Patients with a prevalently nodular pattern developed cystic lesions during follow-up. Interestingly, significant correlations were found between the extent of cystic lesions and DLCO values at onset (time 0: p<0.05) and at the end of follow-up (time 1, p<0.05) and with FEV1 values at time 0 (p<0.05) and time 1 (p<0.05). Patients with progressive functional decline were those with CT evidence of severe cystic alterations. The results suggest that high resolution CT scan of the chest is mandatory for characterizing PLCH patients at diagnosis and during follow-up. The proposed CT score of the chest showed potential prognostic value. PMID:21549535

    Objective This study examined the ecological validity and clinical utility of NIH Patient Reported-Outcomes Measurement Information System (PROMIS®) instruments for anger, depression, and fatigue in women with premenstrual symptoms. Methods One-hundred women completed daily diaries and weekly PROMIS assessments over 4 weeks. Weekly assessments were administered through Computerized Adaptive Testing (CAT). Weekly CATs and corresponding daily scores were compared to evaluate ecological validity. To test clinical utility, we examined if CATs could detect changes in symptom levels, if these changes mirrored those obtained from daily scores, and if CATs could identify clinically meaningful premenstrual symptom change. Results PROMIS CAT scores were higher in the pre-menstrual than the baseline (ps < .0001) and post-menstrual (ps < .0001) weeks. The correlations between CATs and aggregated daily scores ranged from .73 to .88 supporting ecological validity. Mean CAT scores showed systematic changes in accordance with the menstrual cycle and the magnitudes of the changes were similar to those obtained from the daily scores. Finally, Receiver Operating Characteristic (ROC) analyses demonstrated the ability of the CATs to discriminate between women with and without clinically meaningful premenstrual symptom change. Conclusions PROMIS CAT instruments for anger, depression, and fatigue demonstrated validity and utility in premenstrual symptom assessment. The results provide encouraging initial evidence of the utility of PROMIS instruments for the measurement of affective premenstrual symptoms. PMID:24630180

    A method and apparatus for measuring changes in intracranial pressure (ICP) utilizing the variation of the surface wave propagation parameters of the patient's skull to determine the change in ICP. In one embodiment, the method comprises the steps of transmitting an ultrasonic bulk compressional wave onto the surface of the skull at a predetermined angle with respect to the skull so as to produce a surface wave, receiving the surface wave at an angle with respect tn the skull which is substantially the same as the predetermined angle and at a location that is a predetermined distance from where the ultrasonic bulk compressional wave was transmitted upon the skull, determining the retardation or advancement in phase of the received surface wave with respect to a reference phase, and processing the determined retardation or advancement in phase to determine circumferential expansion or contraction of the skull and utilizing the determined circumferential change to determine the change in intracranial pressure.

    Background With the advent of the direct-acting antiviral agents (DAAs), significant drug-drug interaction (DDI) potential now exists for patients treated for chronic hepatitis C virus (HCV) infection. However, little is known about how often patients with HCV use medications that may interact with newer HCV treatments, especially those with CYP3A DDI potential. Methods Using a large United States commercial insurance database, medication use and comorbidity burden was examined among adult patients with a chronic HCV diagnosis from 2006-2010. Medications were examined by total number of prescription claims, proportion of patients exposed, and DDI potential with prototypical CYP3A DAAs, boceprevir and telaprevir, for which data were available. Results Patient comorbidity burden was high and increased over the study period. Medication use was investigated in 53,461 patients with chronic HCV. Twenty-one (53%) of the top 40 most utilized medications were classified as having interaction potential, with 62% of patients received at least one of the top 22 interacting medications by exposure. Of these, 59% and 41% were listed in a common DDI resource but not in medication prescribing information, 77% and 77% had not been investigated in DDI studies, 32% and 27% did not have clear recommendations for DDI management, and only 14% and 23% carried a recommendation to avoid coadministration for boceprevir and telaprevir, respectively. Conclusion Practitioners may expect a medication with CYP3A DDI potential in two-thirds of patients with HCV and almost one-half of the most frequently used medications. However, DDI potential may not be reflected in prescribing information. PMID:25014625

    Sequencing of the mutant allele fraction of circulating cell-free DNA (cfDNA) derived from tumors is increasingly utilized to detect actionable genomic alterations in cancer. We conducted a prospective blinded study of a comprehensive cfDNA sequencing panel with 54 cancer genes. To evaluate the concordance between cfDNA and tumor DNA (tDNA), sequencing results were compared between cfDNA from plasma and genomic tumor DNA (tDNA). Utilizing next generation digital sequencing technology (DST), we profiled approximately 78,000 bases encoding 512 complete exons in the targeted genes in cfDNA from plasma. Seventy-five patients were prospectively enrolled between February 2013 and March 2014, including 61 metastatic cancer patients and 14 clinical stage II CRC patients with matched plasma and tissue samples. Using the 54-gene panel, we detected at least one somatic mutation in 44 of 61 tDNA (72.1%) and 29 of 44 (65.9%) cfDNA. The overall concordance rate of cfDNA to tDNA was 85.9%, when all detected mutations were considered. We collected serial cfDNAs during cetuximab-based treatment in 2 metastatic KRAS wild-type CRC patients, one with acquired resistance and one with primary resistance. We demonstrate newly emerged KRAS mutation in cfDNA 1.5 months before radiologic progression. Another patient had a newly emerged PIK3CA H1047R mutation on cfDNA analysis at progression during cetuximab/irinotecan chemotherapy with gradual increase in allele frequency from 0.8 to 2.1%. This blinded, prospective study of a cfDNA sequencing showed high concordance to tDNA suggesting that the DST approach may be used as a non-invasive biopsy-free alternative to conventional sequencing using tumor biopsy.

    In the past decade, all Canadian provinces and territories have launched various team-based primary healthcare initiatives designed to improve access and continuity of care. Nurse practitioners (NPs) are increasingly becoming integral members of primary healthcare teams across the country. This paper draws on the results of a scoping review of the literature and qualitative key informant interviews conducted for a decision support synthesis about advanced practice nursing in Canada. We describe and analyze two novel approaches to NP integration designed to address the gap in patient access to primary healthcare: (1) the integration of NPs in traditional fee-for-service practices in British Columbia, and (2) the creation of NP-led clinics in Ontario. Although fee-for-service remuneration has been a barrier to collaborative practice, the integration of government-salaried NPs into fee-for-service practices in British Columbia has enabled the creation of inter-professional teams, and based on early evaluation findings, has increased patient access to care and patient and provider satisfaction. NP-led clinics are designed to provide inter-professional care in communities with high numbers of patients who do not have a regular primary healthcare provider. Given the shortage of physicians in communities where these clinics are being introduced, the ratio of physicians to NPs is lower than in other primary healthcare delivery models, and physicians function in more of a consulting role. Initial evaluation of the first of 26 NP-led clinics indicates increased access to care and high levels of patient and provider satisfaction. Implementing a creative mosaic of collaborative primary healthcare models that are responsive to patient needs challenges traditional assumptions about professional roles and responsibilities. To address this challenge, we endorse a recommendation that governments establish a mechanism to bring together both physician and non-physician primary

    Meropenem is a restricted, broad spectrum and expensive antibiotic. The major consequences of irrational use of restricted antibiotics are increase drug resistance and drug expenditure. The use of antibiotics, specifically restricted antibiotics, must be monitored continuously to increase its adherence to the standard guidelines to avoid such problems. The objective of this study was to evaluate the appropriateness of meropenem use with respect to renal status of patients in a teaching based hospital. A retrospective study was carried out from 1st January 2013 to 30th June 2013 to determine the evaluation of meropenem use in accordance to the criteria developed through national (Infectious disease society of Pakistan) and international guidelines (Health care infection control practices advisory committee). The data was recorded on data collection form by thorough reviewing of patients' medical records. Main outcomes measured were indication, dose, interval, duration, creatinine clearance, complete blood count and culture sensitivity test. Correlation of different variable (side effects and generalized health) was also observed with reference to renal status of patients. Statistical analyses were performed using descriptive statistics. A total of 201 cases of meropenem prescription were identified during the study period. The variable, which was most consistent with the criteria was 'indication', in which 97.52% of meropenem prescription was indicated in diseases encouraged by guidelines. However, the use of meropenem as an empirical therapy was the major problem reported in this study as it adhered to in only 43% of the cases. It was also noted that prevalence of side effects increased when meropenem was prescribed in renal compromised patients, and also observed that generalized health of patients decreased with meronem use in renal unstable patients. Thrombocytopenia was the major problem associated with the meropenem use (37.81%). The study detected various

    Hepatitis C virus core antigen (HCV Ag) is a recently developed marker of hepatitis C virus (HCV) infection. We investigated the clinical utility of the new HCV Ag assay for prediction of treatment response in HCV infection. We analyzed serum from 92 patients with HCV infection who had been treated with pegylated interferon and ribavirin. HCV Ag levels were determined at baseline in all enrolled patients and at week 4 in 15 patients. Baseline HCV Ag levels showed good correlations with HCV RNA (r = 0.79, P < 0.001). Mean HCV Ag levels at baseline were significantly lower in patients with a sustained virologic response (SVR) than in those with a non SVR (relapse plus non responder) based on HCV RNA analysis (2.8 log₁₀fmol/L vs. 3.27 log₁₀fmol/L, P = 0.023). Monitoring of the viral kinetics by determination of HCV RNA and HCV Ag levels resulted in similarly shaped curves. Patients with undetectable HCV Ag levels at week 4 had a 92.3% probability of achieving SVR based on HCV RNA assay results. The HCV Ag assay may be used as a supplement for predicting treatment response in HCV infection, but not as an alternative to the HCV RNA assay. PMID:27510387

    The purpose of this quantitative exploratory descriptive survey was to determine which problems pregnant student nurses experienced in the Northern Province (NP) of the Republic of South Africa (RSA). Questionnaires were completed by 93 pregnant student nurses in this province, indicating that the majority of them became pregnant because they lacked knowledge about contraceptives, emergency contraceptives, and termination of pregnancy (TOP) services (legalized in the RSA since 1996). They delayed seeking prenatal care and experienced tiredness, dizziness, and vaginal bleeding during the first trimester. Most pregnant student nurses encountered academic problems as a result of their pregnancies. These and other results indicate a dire need to educate the student nurses about contraceptives and about accessing reproductive health care services. If the students do not utilize the available services themselves, it is unlikely that they will advise their clients to utilize such services. PMID:11822561

    Combined positron emission tomography (PET) and computed tomography (CT) scans are widely used in the staging and monitoring of most malignancies. The differential for PET-positive cutaneous lesions includes primary skin cancers, infections, cutaneous metastases from distant malignancies, and benign neoplasms. In dermatology, PET/CT scans have been most widely studied in patients with melanoma and Merkel cell carcinoma. The role of PET/CT scans in the management of other cutaneous malignancies is less clear, but it has shown great promise in the management of patients with squamous cell carcinoma and cutaneous lymphoma. This review seeks to address the usefulness of PET/CT scans in nonmelanoma skin cancer and to provide guidance regarding the management of patients with incidental PET-positive nodules. Currently, there is limited experience with PET/CT scans for staging and monitoring of non-head and neck metastatic basal cell and squamous cell carcinomas, and results show limited sensitivity and specificity. We also address the evidence for management of an incidental PET-positive cutaneous nodule and recommend obtaining a biopsy specimen in patients with a known noncutaneous malignancy, a history of primary skin cancer, or a high risk of either cutaneous or noncutaneous malignancy.

    A uniform protein profile of bands at 34, 43, and 52 kDa was obtained with all the cerebrospinal fluid (CSF) samples of malaria (10 in number) and non-malaria patients (31 in number) by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). An immunoreactive band was observed at 43 kDa in CSF samples of cerebral malaria patients but not in non-malaria cases when tested with rabbit anti-Plasmodium falciparum antibodies by Western blot analysis. Eleven reactive monoclonal antibodies against P. falciparum were stabilized and expanded. Nine monoclonal antibodies were reactive to CSF samples of cerebral malaria and non-malaria and P. falciparum antigen by dot-ELISA and a common immunoreactive band at 43 kDa by Western blot. One clone Cl-2 was reactive at 43 kDa with CSF of the cerebral malaria patients and also in P. falciparum antigen but at 66 kDa with non-malarial CSF samples in Western blot. The other two clones (Cl-6 and 14) reacted with 3/31 (90% specific) and 8/31 (74%) CSF samples of non-malaria patients, respectively. The monoclonal antibody based ELISA reported in the present study using clone-6 can therefore offer another possibility for developing rapid, easy-to-perform, low-cost tests for diagnosis of cerebral malaria in CSF samples. Western blot using clone-2 might be useful for the detection of cerebral malaria antigen in CSF. PMID:18707548

    Rett syndrome (RTT) is a rare, severe disorder of neuronal plasticity that predominantly affects girls. Girls with RTT usually appear asymptomatic in the first 6–18 months of life, but gradually develop severe motor, cognitive, and behavioral abnormalities that persist for life. A predominance of neuronal and synaptic dysfunction, with altered excitatory–inhibitory neuronal synaptic transmission and synaptic plasticity, are overarching features of RTT in children and in mouse models. Over 90% of patients with classical RTT have mutations in the X-linked methyl-CpG-binding (MECP2) gene, while other genes, including cyclin-dependent kinase-like 5 (CDKL5), Forkhead box protein G1 (FOXG1), myocyte-specific enhancer factor 2C (MEF2C), and transcription factor 4 (TCF4), have been associated with phenotypes overlapping with RTT. However, there remain a proportion of patients who carry a clinical diagnosis of RTT, but who are mutation negative. In recent years, next-generation sequencing technologies have revolutionized approaches to genetic studies, making whole-exome and even whole-genome sequencing possible strategies for the detection of rare and de novo mutations, aiding the discovery of novel disease genes. Here, we review the recent progress that is emerging in identifying pathogenic variations, specifically from exome sequencing in RTT patients, and emphasize the need for the use of this technology to identify known and new disease genes in RTT patients.

    2013-01-01

    Background Dementia patients are often cared for in institutional arrangements, which are associated with substantial spending on professional long-term care services. Nevertheless, there is little evidence on the exact cost differences between community-based and institutional dementia care, especially when it comes to the distinct health care services. Adopting the perspective of the German social security system, which combines Statutory Health Insurance and Compulsory Long-Term Care Insurance (payer perspective), our study aimed to compare community-living and institutionalized dementia patients regarding their health care service utilization profiles and to contrast the respective expenditures. Methods We analysed 2006 claims data for 2,934 institutionalized and 5,484 community-living individuals stratified by so-called care levels, which reflect different needs for support in activities of daily living. Concordant general linear models adjusting for clinical and demographic differences were run for each stratum separately to estimate mean per capita utilization and expenditures in both settings. Subsequently, spending for the community-living and the institutionalized population as a whole was compared within an extended overall model. Results Regarding both settings, health and long-term care expenditures rose the higher the care level. Thus, long-term care spending was always increased in nursing homes, but health care spending was comparable. However, the underlying service utilization profiles differed, with nursing home residents receiving more frequent visits from medical specialists but fewer in-hospital services and anti-dementia drug prescriptions. Altogether, institutional care required additional yearly per capita expenses of ca. €200 on health and ca. €11,200 on long-term care. Conclusion Community-based dementia care is cost saving from the payer perspective due to substantially lower long-term care expenditures. Health care spending is

    Pain is a common complication after spinal cord injury with prevalence estimates ranging 77% to 81%, which highly affects a patient's lifestyle and well-being. In the current clinical setting paper-based forms are used to classify pain correctly, however, the accuracy of diagnoses and optimal management of pain largely depend on the expert reviewer, which in many cases is not possible because of very few experts in this field. The need for a clinical decision support system that can be used by expert and non-expert clinicians has been cited in literature, but such a system has not been developed. We have designed and developed a stand-alone tool for correctly classifying pain type in spinal cord injury (SCI) patients, using Bayesian decision theory. Various machine learning simulation methods are used to verify the algorithm using a pilot study data set, which consists of 48 patients data set. The data set consists of the paper-based forms, collected at Long Beach VA clinic with pain classification done by expert in the field. Using the WEKA as the machine learning tool we have tested on the 48 patient dataset that the hypothesis that attributes collected on the forms and the pain location marked by patients have very significant impact on the pain type classification. This tool will be integrated with an imaging informatics system to support a clinical study that will test the effectiveness of using Proton Beam radiotherapy for treating spinal cord injury (SCI) related neuropathic pain as an alternative to invasive surgical lesioning.

    Reliable, valid, and brief measures of mood state are essential to the evaluation of electroconvulsive therapy (ECT) efficacy. However, existing measures of mood state may be inappropriate for patients with transient cognitive impairment. Stern and colleagues have recently developed a set of Visual Analog Mood Scales (VAMS) for use in neurologically impaired patients. These brief scales (including measures of sad, confused, afraid, happy, tired, angry, and energetic states) are easily administered and have documented reliability and validity in neurologically impaired patients and in healthy adult and geriatric samples. In the present study, we assessed the validity and sensitivity of the VAMS to detect ECT-related mood change. Twenty-five inpatients who were diagnosed with major depressive episode and referred for ECT were administered the VAMS and the Hamilton Depression Rating Scale (HDRS) both pre- and post-ECT. Results indicate that the VAMS are as sensitive to the therapeutic effects of ECT as is the more lengthy and verbally demanding HDRS. In addition, the VAMS were highly correlated with the clinician's Clinical Global Improvement rating and the patient's self-report using a modified Center for Epidemiological Studies-Depression scale. The VAMS are brief, reliable scales that are sensitive to the treatment effects of ECT and that are appropriate for patients with transient cognitive impairment. PMID:9034694

    Purpose: Treatment plans for the TomoTherapy unit are produced with a planning system that is integral to the unit. The authors have produced an independent dose calculation system, to enable plans to be recalculated in three dimensions, using the patient's CT data. Methods: Software has been written using MATLAB. The DICOM-RT plan object is used to determine the treatment parameters used, including the treatment sinogram. Each projection of the sinogram is segmented and used to calculate dose at multiple calculation points in a three-dimensional grid using tables of measured beam data. A fast ray-trace algorithm is used to determine effective depth for each projection angle at each calculation point. Calculations were performed on a standard desktop personal computer, with a 2.6 GHz Pentium, running Windows XP. Results: The time to perform a calculation, for 3375 points averaged 1 min 23 s for prostate plans and 3 min 40 s for head and neck plans. The mean dose within the 50% isodose was calculated and compared with the predictions of the TomoTherapy planning system. When the modified CT (which includes the TomoTherapy couch) was used, the mean difference for ten prostate patients, was -0.4% (range -0.9% to +0.3%). With the original CT (which included the CT couch), the mean difference was -1.0% (range -1.7% to 0.0%). The number of points agreeing with a gamma 3%/3 mm averaged 99.2% with the modified CT, 96.3% with the original CT. For ten head and neck patients, for the modified and original CT, respectively, the mean difference was +1.1% (range -0.4% to +3.1%) and 1.1% (range -0.4% to +3.0%) with 94.4% and 95.4% passing a gamma 4%/4 mm. The ability of the program to detect a variety of simulated errors has been tested. Conclusions: By using the patient's CT data, the independent dose calculation performs checks that are not performed by a measurement in a cylindrical phantom. This enables it to be used either as an additional check or to replace phantom

    Transarterial chemoembolization (TACE) is the well-known treatment for hepatocellular carcinoma. Multiple digital subtraction angiography (DSA) acquisitions in different projections are required to identify difficult arterial feeders. Moreover, the tell-tale tumor blush can be obscured by proximity to lung base, small size of lesion, and breathing artifacts. C-arm CT is a revolutionary advancement in the intervention radiology suite that allows acquisition of data which can be reformatted in multiple planes and volume rendered incorporating both soft tissue and vascular information like multidetector computed tomography (MDCT). These images acquired during the TACE procedure can provide critical inputs for achieving a safe and effective therapy. This case series aims to illustrate the utility of C-arm CT in solving specific problems encountered while performing TACE. PMID:24851011

    Single ventricle anomalies are a challenging set of congenital heart defects that require lifelong clinical management due to progressive decline of cardiovascular function. Few therapeutic devices are available for these patients, and conventional blood pumps are not designed for the unique anatomy of the single ventricle physiology. To address this unmet need, we are developing an axial flow blood pump with a protective cage or stent for Fontan patients. This study investigates the 3-D particle image velocimetry measurements of two cage designs being deployed in a patient-specific Fontan anatomy. We considered a control case without a pump, impeller placed in the inferior vena cava, and two cases where the impeller has two protective stents with unique geometric characteristics. The experiments were evaluated at a cardiac output of 3 L/min, a fixed vena caval flow split of 40%/60%, a fixed pulmonary arterial flow split of 50%/50%, and for operating speeds of 1000-4000 rpm. The introduction of the cardiovascular stents had a substantial impact on the flow conditions leaving the pump and entering the cavopulmonary circulation. The findings indicated that rotational speeds above 4000 rpm for this pump could result in irregular flows in this specific circulatory condition. Although retrograde flow into the superior vena cava was not measured, the risk of this occurrence increases with higher pump speeds. The against-with stent geometry outperformed the other configurations by generating higher pressures and more energetic flows. These results provide further support for the viability of mechanical cavopulmonary assistance as a therapeutic treatment strategy for Fontan patients. PMID:25597518

    Two patients presenting with progressive dementia coupled with motor neuron disease underwent brain SPECT using N-isopropyl-p iodine-123-iodoamphetamine (({sup 123}I)IMP). The characteristic clinical features of progressive dementia and motor neuron disease were noted. IMP SPECT also revealed reduced uptake in the bilateral frontal and temporal regions, with no reduction of uptake in the parietal, parietal-occipital regions. We conclude that IMP SPECT has potential for the evaluation of progressive dementia with motor neuron disease.

    We assessed the usefulness of in situ hybridization with a DNA probe to the area of chromosome 17 at p11.2 as a diagnostic tool for screening for Charcot Marte Tooth 1A (CMT 1A). In situ hybridization with a probe to 17p11.2 was performed on fixed lymphocytes from the following groups of individuals: (1) normal controls; (2) patients evoking a strong clinical suspicion of CMT 1A; and (3) 3 families with an apparent autosomal dominant peripheral neuropathy of unknown diagnoses. Group 2 patients had evidence of demyelination as defined by nerve conduction of less that 50% of the normal mean or terminal latency greater than 50% of the normal mean in conduction studies. Analysis of interphase cells hybridized with a cosmid DNA probe to 17p11.2 requires inclusion of a normal control with each trial and masked observer. Due to the size of the target DNA and the nature of the centromeric heterochromatin, the scoring of this probe is more subjective than centromere probes. For example, if the two 17 chromosomes are decondensed as in interphase, two tandem signals may be visualized as one. Results from duplication positive patients demonstrate a large proportion of cells with two closely aligned, but separate, signals with an additional single signal. Normal results demonstrate a majority of cells with two separate signals representing both normal homologues. None of the 3 families with questionable diagnosis revealed a duplication at the region, reinforcing our belief that a clinical diagnosis is the most discriminating tool available for diagnosis of CMT 1A. We concur with Boylan that molecular analysis for CMT 1A is useful for establishing a diagnosis of CMT 1A, but is not a primary differential diagnostic test. The yield in screening patients without physiologic evidence of demyelination is likely to be low. We further find that the use of in situ hybridization is a simple method of performing the duplication analysis.

    Abstract Approximately 3 million patients with symptoms suggestive of obstructive coronary artery disease (CAD) present to primary care offices in the United States annually, resulting in approximately $6.7 billion in cardiac workup costs. Despite wide application of existing diagnostic technologies, yield of obstructive CAD at invasive coronary angiography (ICA) is low. This study used a decision analysis model to assess the economic utility of a novel gene expression score (GES) for the diagnosis of obstructive CAD. Within a representative commercial health plan's adult membership, current practice for obstructive CAD diagnosis (usual care) was compared to a strategy that incorporates the GES test (GES-directed care). The model projected the number of diagnostic tests and procedures performed, the number of patients receiving medical therapy, type I and type II errors for each strategy of obstructive CAD diagnosis, and the associated costs over a 1-year time horizon. Results demonstrate that GES-directed care to exclude the diagnosis of obstructive CAD prior to myocardial perfusion imaging may yield savings to health plans relative to usual care by reducing utilization of noninvasive and invasive cardiac imaging procedures and increasing diagnostic yield at ICA. At a 50% capture rate of eligible patients in GES-directed care, it is projected that a commercial health plan will realize savings of $0.77 per member per month; savings increase proportionally to the GES capture rate. These findings illustrate the potential value of this new blood-based, molecular diagnostic test for health plans and patients in an age of greater emphasis on personalized medicine.

    Approximately 3 million patients with symptoms suggestive of obstructive coronary artery disease (CAD) present to primary care offices in the United States annually, resulting in approximately $6.7 billion in cardiac workup costs. Despite wide application of existing diagnostic technologies, yield of obstructive CAD at invasive coronary angiography (ICA) is low. This study used a decision analysis model to assess the economic utility of a novel gene expression score (GES) for the diagnosis of obstructive CAD. Within a representative commercial health plan's adult membership, current practice for obstructive CAD diagnosis (usual care) was compared to a strategy that incorporates the GES test (GES-directed care). The model projected the number of diagnostic tests and procedures performed, the number of patients receiving medical therapy, type I and type II errors for each strategy of obstructive CAD diagnosis, and the associated costs over a 1-year time horizon.

    Introduction. Future health care providers need to be trained in the knowledge and skills to effectively communicate with their patients with limited health literacy. The purpose of this study is to develop and evaluate a curriculum designed to increase residents' health literacy knowledge, improve communication skills, and work with an interpreter. Materials and Methods. Family Medicine residents (N = 25) participated in a health literacy training which included didactic lectures and an objective structured clinical examination (OSCE). Community promotoras acted as standardized patients and evaluated the residents' ability to measure their patients' health literacy, communicate effectively using the teach-back and Ask Me 3 methods, and appropriately use an interpreter. Pre- and postknowledge, attitudes, and postdidactic feedback were obtained. We compared OSCE scores from the group that received training (didactic group) and previous graduates. Residents reported the skills they used in practice three months later. Results. Family Medicine residents showed an increase in health literacy knowledge (p = 0.001) and scored in the adequately to expertly performed range in the OSCE. Residents reported using the teach-back method (77.8%) and a translator more effectively (77.8%) three months later. Conclusions. Our innovative health literacy OSCE can be replicated for medical learners at all levels of training. PMID:26491565

    The purpose of this study was to assess the utility and validity of using customized heterochromatic flicker photometry (cHFP) to measure macular pigment optical density (MPOD) in patients with intermediate stages of age-related macular degeneration (AMD). The measurement procedure was optimized to accommodate individual differences in temporal vision related to age, disease, or other factors. The validity criteria were based on the similarity of the spectral absorption curves to ex vivo curves of lutein and zeaxanthin and the similarity of spatial density profiles to those measured in subjects without retinal disease. Macular pigment optical density (MPOD) spatial profiles were measured with an LED-based macular densitometer; spectral absorption curves were measured with a 3-channel Maxwellian view system including a monochromator. All patients were characterized via clinical exams and all but 2 subjects from whom data were obtained had masked grading of color fundus photographs using the Wisconsin Age-Related Maculopathy Grading System. Most of the patients were in AREDS category 2 (27%) or 3 (57%). Patients with visual acuity as poor as 20/80 were included, and could perform the task as long as they could see the stimulus. Eighty-one percent of the patients screened were able to perform the cHFP task, and data were obtained from 30 AMD patients. Spatial profiles of MPOD were measured in 19 subjects who could see the stimulus at all tested loci. These profiles were highly similar to those that have been measured with HFP in subjects without retinal disease. The average shape of the spectral absorption curves for the AMD subjects corresponded well to an ex vivo template. These data support both the utility and validity of the cHFP method for measuring MPOD in subjects with intermediate stages of AMD. The ability to measure the retinal response to nutritional intervention is of practical importance for monitoring patients being supplemented with lutein and

    We present a 38-year-old male patient with insulin requiring type 2 diabetes mellitus (DM) who had fasting hypoglycemia caused by a non-pancreatic-islet-cell mesenchymal tumor producing IGF-II. The evaluation was confounded in that there was pre-existing DM being treated with insulin analogs. Insulin levels were assessed with an immunoassay with cross reactivity with the insulin analogs. An 18-Fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) scan localized the 19.7×18.0×17.8cm retroperitoneal mass. A 3.25kg tumor was resected. Post-operatively insulin treatment was resumed and circulating IGF-II levels returned to normal. The maximum standardized uptake values of FDG (SUVmax) along with a steady state glucose infusion of 17.5g/h were used to determine the components of glucose utilization due to IGF-II induced muscle glucose uptake (utilization, 62%) whereas the tumor itself was responsible for approximately 22% of measurable glucose uptake. Whereas tumor induced hypoglycemia has been ascribed to preferential glucose utilization by the tumor, the predominant hypoglycemic effect was due to hormonal IGF-II induced total body glucose uptake.

    Aim. The clinical utility of digital linear tomosynthesis in musculoskeletal applications has been validated in only a few reports. Technical performance and utility in hip prosthesis imaging have been discussed in technical reports, but no clinical evaluation has been reported. The purpose of the current study was to assess the added clinical utility of digital linear tomosynthesis compared to radiography in loosening of total hip joint arthroplasty. Materials and Methods. In a prospective study, radiography and digital tomosynthesis were performed in 40 consecutive patients with total hip arthroplasty referred for suspect prosthesis loosening. Tomosynthesis images were compared to anterior-posterior (AP) and cross-table lateral radiographs regarding demarcation and extent of demineralization and osteolysis. Further noted were skeletal fractures, cement fractures, fragmentation, and artifacts interfering with the diagnosis. Results. Tomosynthesis was superior to radiography with sharper delineation of demineralization and osteolysis in the AP projection. A limitation was the inability to generate lateral tomosynthesis images, with inferior assessment of the area anterior and posterior to the acetabular cup compared to cross-table radiographs. Artifacts interfering with diagnosis were found in one hip. Conclusion. Tomosynthesis improved evaluation of total hip arthroplasty in the AP projection but was limited by the lack of lateral projections. PMID:24078921

    The aim of this study was to compare patient characteristics, utilization rates, and outcomes after total elbow arthroplasty (TEA) by sex. We used the nationwide inpatient sample from 1998 to 2011 to study sex-related time trends in patient characteristics, comorbidity, and outcomes after TEA. We used chi-squared test, analysis of variance, and the Cochran-Armitage test to assess differences in utilization rates and characteristics over time by sex and logistic regression to compare mortality, discharge disposition, and the length of hospital stay by sex. Overall TEA utilization 0.45 in 1998 to 0.96 per 100,000 in 2011 (p < 0.0001). The utilization rates were significantly higher in females compared to males throughout the study period: 0.62 vs. 0.29 in 1998 (p < 0.0001) and 1.31 vs. 0.70 in 2011 (p < 0.0001). Compared to males, females undergoing TEA were more likely to be white (79.7 vs. 71.4 %; p < 0.0001), have rheumatoid arthritis (16.7 vs. 8.1 %; p < 0.0001), and have Deyo-Charlson index of 2 or more (11.3 vs. 5.9 %; p < 0.0001) and were older (63.5 vs. 51.4 years; p < 0.0001). Compared to males undergoing TEA, females had significantly lower mortality, 0.1 vs. 0.4 % (p = 0.03); lower proportion were discharged to home, 81.9 vs. 89.6 % (p < 0.0001), and fewer had has index hospital stay above the median, 30.0 vs. 33.0 % (p = 0.01); most differences were significant after multivariable adjustment. TEA utilization in the USA more than doubled in the last 14 years, with rates higher in females than males. Females had better outcomes after TEA than men. Preoperative risk communication should be sex-specific based on these data. PMID:25316506

    A sample of 148 (87 Jordanian [61 male, 26 female] and 61 Israeli [26 male, 35 female]) was selected from a psychiatric clinic in Ashdod Israel and Zarka Jordan, using convenience sampling methodology over a 12 month period in late 1997 and early 1998. A revised Hopkins Symptom Checklist: A Self-Report Symptom Inventory (HSCL) was translated into Arabic and Hebrew and distributed to subjects; additional questions explored demographic characteristics, forms of received treatment, patient perceptions of treatment efficacy, patient use of traditional healers, and patient explanation of etiology. Data revealed that there were differences in dimensions between the 2 groups based on nationality and gender. More Jordanians than Israelis expected medications as the main treatment, and unlike Israelis, no Jordanian patients received individual psychotherapy. Israelis expected medications, advice, directions, and instructions from psychiatrists. Both ethnic groups consulted a wide array of traditional healers, although precise types of healers varied according to gender and ethnicity. Israeli subjects gave more diverse explanations of mental health etiologies: physical, family, divorce, economic, unemployment; whereas Jordanians tended to emphasize divine and spiritual sources. Implications for psychiatric practice are discussed. PMID:11589335

    Weights associated with the EuroQol 5-Dimension 3-Level (EQ-5D-3L) instrument represent preferences for health states elicited from general population's samples. Weights have not been calculated for every country; however, empirical research shows that cross-country differences exist. This empirical study aims at investigating the impact of recently developed Italian weights in comparison with UK and US scores on health-related utility calculation using a sample of patients with Crohn's disease. The study is based on a survey on health-related quality of life in patients (n=552) affected by active Crohn's disease conducted in Italy from 2012 to 2013. Utilities computed through the Italian algorithm (mean: 0.76; SD: 0.20; median: 0.81) are generally higher than US (mean: 0.69; SD: 0.22; median: 0.77) and UK (mean: 0.57; SD: 0.32; median: 0.69) utilities, except for extremely severe health states where US values outweigh the Italian ones. UK preference weights generate the highest number of negative results. All the three value distributions are left-skewed due to very low scores associated with the most serious health states (ie, three or four levels equal to 3). As expected, despite the tariff set considered, more severe disease (Harvey Bradshaw Index >16) reduces the mean conditional EQ-5D-3L index (P<0.0001). Kendall's rank correlation between EQ Visual Analog Scale score and EQ-5D-3L index is positive (P<0.0001), even though patients tend to value their health-related quality of life more when responding to EQ-5D-3L questions than on EQ Visual Analog Scale. Regardless of the tariff set considered, ordinary least-square results highlight that more severe disease (Harvey Bradshaw Index >16) reduces the mean conditional EQ-5D-3L index (P<0.0001). Results reveal remarkable differences among the three national tariff sets and especially when severe health states occur, suggesting the need for country-specific preference weights when evaluating utilities, which can be

    The objective of the present study was to evaluate the reliability and clinical utility of a Portuguese version of the Abnormal Involuntary Movements Scale (AIMS). Videotaped interviews with 16 psychiatric inpatients treated with antipsychotic drugs for at least 5 years were evaluated. Reliability was assessed by the intraclass correlation coefficient (ICC) between three raters, two with and one without clinical training in psychopathology. Clinical utility was assessed by the difference between the scores of patients with (N = 11) and without (N = 5) tardive dyskinesia (TD). Patients with TD exhibited a higher severity of global evaluation by the AIMS (sum of scores: 4.2 +/- 0.9 vs 0.4 +/- 0.2; score on item 8: 2.3 +/- 0.3 vs 0.4 +/- 0.2, TD vs controls). The ICC for the global evaluation was fair between the two skilled raters (0.58-0.62) and poor between these raters and the rater without clinical experience (0.05-0.29). Thus, we concluded that the Portuguese version of the AIMS shows an acceptable inter-rater reliability, but only between clinically skilled raters, and that it is clinically useful. PMID:12700830

    Understanding the association between the bacterial community and oral health status is essential for the diagnosis and therapy of periodontal diseases. The aim of the present study was to apply three methods [conventional culture, substrate utilization using the MicroResp™ system and terminal restriction fragment length polymorphism (T-RFLP)] to investigate the oral bacterial community in saliva from 20 healthy subjects and 20 patients with periodontitis. The three methods all revealed that there was a systematic change in the microbial ecological characteristics associated with oral health status. Compared with the control group, the oral bacterial flora in the patients with chronic periodontitis had a greater culturable population and altered preferred carbon source and TRFLP patterns. TRFLP analysis was found to give more information and exhibit a higher sensitivity than the substrate utilization and conventional culture methods. In conclusion, TRFLP analysis is a potentially rapid method to assess the composition of the oral microbial community and for the diagnosis of chronic periodontitis. PMID:26136931

    The aim of the present study was to construct a cost-effective noninvasive diagnostic index for prediction of hepatic steatosis in patients with hepatitis B virus(HBV) infection. From January 2011 to January 2015, a total of 364 consecutive subjects who underwent liver biopsies were enrolled. The Receiver-operating characteristic(ROC) curves and Obuchowski measure were constructed to evaluate the diagnostic accuracy of the new index. The AUROCs of steatosis index of patients with HBV infection (SIHBV) in predicting of steatosis were 0.929 (95% confidence interval:0.889–0.970, P < 0.05) in the model group and 0.855 (0.794–0.917, P < 0.05) in the validation group respectively. Comparisons of AUROCs demonstrated that SIHBV was significantly superior to Korean Score, fatty liver index (FLI), hepatic steatosis index (HSI), lipid accumulation product(LAP), and fatty liver disease (FLD) index for prediction of hepatic steatosis in model group and validation group(all P < 0.01). Especially for patients with hepatic steatosis percentage of 5.0–9.9% and 10.0–19.9%, SIHBV had a sensitivity of 63.6% and 79.2%, whereas it were 29.1% and 45.8% for Ultrasonography (all P < 0.05). In conclusion, as a cost-effective, simple, noninvasive, and readily available method, SIHBV may act as a massive screening tool before further examinations such as MRI, CT, transient elastography, or liver biopsy, especially for developing countries.
