To investigate clinically significant change in the emotional condition of relatives of patients with severe traumatic brain injury during sub-acute rehabilitation. Participants were 62 pairs of relatives and patients. Relatives completed the anxiety and depression scales from the Symptom Checklist-90-R (SCL-90-R) when the patients were admitted to sub-acute rehabilitation and at discharge. Improvement in emotional condition was investigated using the following criteria: (i) statistically reliable improvement; and (ii) clinically significant change (CSC). At admission, 53.2% and 58.1% of relatives had scores above cut-off values on the anxiety and depression scales, respectively. On the anxiety scale 69.7% of these experienced a reliable improvement according to the Reliable Change Index (RCI) and 45.5% also obtained CSC, as their end-point was below the cut-off value. On the depression scale the corresponding figures were 44.4% and 41.7%, respectively. When comparing relatives with and without CSC, we found that CSC in symptoms of anxiety was associated with significantly better functional improvement during rehabilitation and a shorter period of post-traumatic amnesia in the patients. Of the relatives who reported scores above cut-off values on the anxiety and depression scales at patient's admission, approximately 40% experienced CSC in anxiety and depression during the patient's rehabilitation. Relatives of patients experiencing improvement during inpatient rehabilitation are more likely to experience CSC in anxiety.

It is imperative that primary care referrals are directed to the appropriate secondary care service. Patients presenting to a primary care physician with ENT conditions may require review in an Emergency Clinic. The latter clinics provide patients with rapid access to secondary care, for urgent, yet non-life-threatening conditions. In our department, we noticed that patients with conditions inappropriate to the capabilities of the Clinic were being booked in or reviewed too late; thus causing wasted journeys for the patient. We conducted a Quality Improvement Project to improve the efficiency of the referral process. A prospective evaluation of referrals was collected continuously over a two-month period. Overall, 5 domains were deemed crucial to enable timely and accurate booking of patients to clinic: booking date, urgency, legibility, patient identification and appropriateness. Our proposed standard set for this project was 100% compliance over the 5 domains. Three separate interventions were instigated following the first cycle. The main components of the intervention were the phased development of an electronic referral system and an educational initiative for junior doctors. 20 referral forms were analysed during the initial 3-week period. No referrals met the recommended overall compliance standard of 100% (mean number of domains achieved: 3.38; standard deviation (SD): 0.637). Legibility and patient information were included in 21% and 30% of referrals, respectively. There was a trend of improvement following initiation of interventions. The mean number of domains achieved was 4.27 (SD 0.647; n=13) in the second data collection period, 4.53 (SD 0.514; n=16) in the third, and 4.75 (SD 0.452; n=24) in the fourth. Using linear regression, this change demonstrates a statistically significant improvement (p<0.001). An e-Proforma referral system represents a safe and efficient communication technology. When implementing policy change, it is crucial to acquire managerial and consultant support.

Diehl, Adam C; Reader, Lauren; Hamosh, Ada; Bodurtha, Joann N

2015-02-01

With the relentless expansion of genetics into every field of medicine, stronger preclinical and clinical medical student education in genetics is needed. The explosion of genetic information cannot be addressed by simply adding content hours. We proposed that students be provided a tool to access accurate clinical information on genetic conditions and, through this tool, build life-long learning habits to carry them through their medical careers. Surveys conducted at the Johns Hopkins University School of Medicine revealed that medical students in all years lacked confidence when approaching genetic conditions and lacked a reliable resource for accurate genetic information. In response, the school created a horizontal thread that stretches across the first-year curriculum and is devoted to teaching students how to use Online Mendelian Inheritance in Man (OMIM) (http://omim.org) and the databases to which it links as a starting point for approaching genetic conditions. The thread improved the first-year students' confidence in clinical genetics concepts and encouraged use of OMIM as a primary source for genetic information. Most students showed confidence in OMIM as a learning tool and wanted to see the thread repeated in subsequent years. Incorporating OMIM into the preclinical curriculum improved students' confidence in clinical genetics concepts.

OBJECTIVES. The aim of the Condition Management Programme (CMP) is to help Incapacity Benefit recipients manage their health conditions more effectively and return to work. This paper seeks to examine the clinical and employment outcomes from a group-based and mixed-condition CMP. DESIGN. In a prospective cohort design, measures of employment status and psychological well-being were taken at three time points; pre-CMP, post-CMP, and at 3-month follow-up. METHOD. Participants (N= 2,064) with a variety of physical and mental health conditions voluntarily attended a seven session cognitive-behaviourally informed psychoeducational group intervention. The psychological measures used were the Clinical Outcomes in Routine Evaluation - Outcome Measure, Work and Social Adjustment Scale, Self-Efficacy Scale, and the Intrinsic Motivation Scale. The employment status of participants was also measured at the three time points of the evaluation. RESULTS. Following CMP, 50% of participants experienced a reliable improvement in psychological well-being and 26% had either taken some steps towards work or returned to work at follow-up. Participants with a mental health condition were more likely to experience a reliable improvement in psychological well-being compared to those with physical health conditions. CONCLUSIONS. The results suggest that participation in CMP may be helpful in facilitating more effective self-management of the health conditions contributing to unemployment. The results have implications for whether formal employment assistance should be available in mental health services. ©2010 The British Psychological Society.

To explore the barriers to and facilitators of adapting and expanding a primary care memory clinic model to integrate care of additional complex chronic geriatric conditions (heart failure, falls, chronic obstructive pulmonary disease, and frailty) into care processes with the goal of improving outcomes for seniors. Mixed-methods study using quantitative (questionnaires) and qualitative (interviews) methods. Ontario. Family physicians currently working in primary care memory clinic teams and supporting geriatric specialists. Family physicians currently working in memory clinic teams (n = 29) and supporting geriatric specialists(n = 9) were recruited as survey participants. Interviews were conducted with memory clinic lead physicians (n = 16).Statistical analysis was done to assess differences between family physician ratings and geriatric specialist ratings related to the capacity for managing complex chronic geriatric conditions, the role of interprofessional collaboration within primary care, and funding and staffing to support geriatric care. Results from both study methods were compared to identify common findings. Results indicate overall support for expanding the memory clinic model to integrate care for other complex conditions. However, the current primary care structure is challenged to support optimal management of patients with multiple comorbidities, particularly as related to limited funding and staffing resources. Structured training, interprofessional teams, and an active role of geriatric specialists within primary care were identified as important facilitators. The memory clinic model, as applied to other complex chronic geriatric conditions, has the potential to build capacity for high-quality primary care, improve health outcomes,promote efficient use of health care resources, and reduce healthcare costs.

[Placebo effect in Parkinson's disease].

PubMed

Miwa, Hideto

2007-02-01

"Placebo" is Latin for "I shall please". The placebo effect has been widely documented by randomized placebo-controlled drug studies. One of the best examples of placebo effectiveness is that have been shown in clinical trials of anti-parkinsonian drugs. The placebo effect is observable not only in drug trials but also with deep brain stimulation. Recent advances in research on the placebo effect in Parkinson's disease (PD) have suggested that motor symptoms of PD can be essentially improved by placebo. A recent study using positron emission tomography (PET) with raclopride demonstrated that release of endogeneous dopamine in the dorsal striatum occurs in placebo-responsive patients with PD. This suggests that placebo-induced expectation of clinical improvement may activate endogenous dopamine in the striatum, and that placebo effectiveness is thus achieved by endogenous dopamine supplementation. Indeed, decreased neuronal activities in the subthalamic nucleus (STN), that were recorded during surgery to implant deep brain stimulation electrodes, correlated well with placebo-induced clinical improvement in patients with PD. Although the detailed pathophysiological mechanism underlying the placebo effects remains uncertain, theoretically, the placebo effect has generally been explained by two different mechanisms: one is conditioning theory (pavlovian conditioning), and the other is cognitive theory (expectation of clinical improvement). Although both mechanisms may contribute to placebo effects, the placebo effect in PD may be attributed more to cognitive mechanisms such as expectation of improvement, because the placebo effect can be obtained in de novo PD patients. There have been accumulating findings that suggest a functional relationship between dopamine and the expectation of clinical improvement (reward). Further basic studies are required to clarify the complex link between dopamine and the reward system, but such findings will contribute to a better understanding of the pathophysiological mechanism underlying the placebo effect in PD.

Appointment systems are essential for improving chronic disease care in resource-poor settings: learning from experiences with HIV patients in Africa.

Lessons learned from treating patients with HIV infection can inform care systems for other chronic conditions. For antiretroviral treatment, attending appointments on time correlates with medication adherence; however, HIV clinics in East Africa, where attendance rates vary widely, rarely include systems to schedule appointments or to track missed appointments or patient follow-up. An introduction of low-cost, paper-based patient appointment and tracking systems led to an improvement in timely clinic attendance rates and tracking missing patients. An effective appointment system is critical to managing patients with chronic conditions and can be introduced in resource-limited settings, possibly without having to add staff.

As such, patients may be managed by a number of specialties, resulting in inconsistent practice and suboptimal care. We describe the development of a dedicated CAT service and its evaluation. Specialist cancer centre, district general hospital and primary care. Patients with CAT and their referring clinicians. A cross specialty team developed a dedicated CAT service , including clear referral pathways, consistent access to medicines, patient's information and a specialist clinic. The service was evaluated using a mixed-methods evaluation , including audits of clinical practice, clinical outcomes, staff surveys and qualitative interviewing of patients and healthcare professionals. Data from 457 consecutive referrals over an 18-month period were evaluated. The CAT service has led to an 88% increase in safe and consistent community prescribing of low-molecular-weight heparin, with improved access to specialist advice and information. Patients reported improved understanding of their condition, enabling better self-management as well as better access to support and information. Referring clinicians reported better care standards for their patients with improved access to expertise and appropriate management. A dedicated CAT service improves overall standards of care and is viewed positively by patients and clinicians alike. Further health economic evaluation would enhance the case for establishing this as the standard model of care. Published by the BMJ Publishing Group Limited.

In the present paper, the authors introduce the approved and finished research projects for acupuncture and moxibustion therapies supported by the National Natural Science Foundation of China (NSFC) during the 11th 5-year-plan. A total of 194 research projects were subsidized by NSFC from 2006 to 2010. These projects include 6 aspects: meridian-collaterals, acupoint theory, acupuncture analgesia, mechanisms underlying improvement of different clinical problems, clinical trials, and moxibustion therapy. The research on acupoints has been becoming a new hotspot in recent years. Majority of the research projects focus on the mechanism of acu-moxibustion underlying improvement of different clinical problems, while fewer projects on clinical trials. During the 11th 5-year-plan, 119 projects were completed; most of them involved meridian-collateral theory, acupoint theory, mechanism of acu-moxibustion underlying improvement of clinical problems and acupuncture manipulations. Following analysis of the finished research projects, we find that 1) many neurobiological methods and techniques are commonly used in the research on meridian-collateral theory; 2) the research on acupoint theory is changing from observing the local morphological structure to identifying characteristics of the regional activated receptors, particularly under the circumstances of visceral pathological conditions and efficacies of acupoints; 3) researches on the underlying mechanism of acu-moxibusiton for improving clinical disorders mainly focused on its cerebral protective effects against cerebral ischemia, in addition, researches about other diseases on clinical conditions have been also carried out, but the related mechanisms are far from understanding; 4) In many research projects, various new methods and techniques, such as fMRI, position emission tomography, genomics, proteomics, molecular biology, nerve stem cell, etc. were widely used; 5) Randomized controlled multi-center clinical trials are definitely insufficient. Only two clinical projects were finished during the 11th 5-year-plan. Moreover, it should be noted that in the subject of acu-moxibustion, independent innovation researches are fewer; the foundation of competitive ability is relatively weaker; the supporting conditions for finishing the research projects are poorer in some institutes or districts; and the interrelations among the theoretical, experimental and clinical researches are not intimately close, leading to relative lag in the subject development.

Introduction Finding ways to provide better and less expensive health care for people with multiple chronic conditions or disability is a pressing concern. The purpose of this systematic review was to evaluate different approaches for caring for this high-need and high-cost population. Methods We searched Medline for articles published from May 31, 2008, through June 10, 2014, for relevant studies. Articles were considered eligible for this review if they met the following criteria: included people with multiple chronic conditions (behavioral or mental health) or disabilities (2 or more); addressed 1 or more of clinical outcomes, health care use and spending, or patient satisfaction; and compared results from an intervention group with a comparison group or baseline measurements. We extracted information on program characteristics, participant characteristics, and significant (positive and negative) clinical findings, patient satisfaction, and health care use outcomes. For each outcome, the number of significant and positive results was tabulated. Results Twenty-seven studies were included across 5 models of care. Of the 3 studies reporting patient satisfaction outcomes, 2 reported significant improvements; both were randomized controlled trials (RCTs). Of the 14 studies reporting clinical outcomes, 12 reported improvements (8 were RCTs). Of the 13 studies reporting health care use and spending outcomes, 12 reported significant improvements (2 were RCTs). Two models of care — care and case management and disease management — reported improvements in all 3 outcomes. For care and case management models, most improvements were related to health care use. For the disease management models, most improvements were related to clinical outcomes. Conclusions Care and case management as well as disease management may be promising models of care for people with multiple chronic conditions or disabilities. More research and consistent methods are needed to understand the most appropriate care for these high-need and high-cost patients. PMID:26564013

Real-time feedback may be useful for enhancing information gained from clinical gait analysis of children with cerebral palsy (CP). It may also be effective in functional gait training, however, it is not known if children with CP can adapt gait in response to real-time feedback of kinematic parameters. Sixteen children with cerebral palsy (age 6-16; GMFCS I-III), walking with a flexed-knee gait pattern, walked on an instrumented treadmill with virtual reality in three conditions: regular walking without feedback (NF), feedback on hip angle (FH) and feedback on knee angle (FK). Clinically relevant gait parameters were calculated and the gait profile score (GPS) was used as a measure of overall gait changes between conditions. All children, except one, were able to improve hip and/or knee extension during gait in response to feedback, with nine achieving a clinically relevant improvement. Peak hip extension improved significantly by 5.1±5.9° (NF: 8.9±12.8°, FH: 3.8±10.4°, p=0.01). Peak knee extension improved significantly by 7.7±7.1° (NF: 22.2±12.0°, FK: 14.5±12.7°, p<0.01). GPS did not change between conditions due to increased deviations in other gait parameters. Responders to feedback were shown to have worse initial gait as measured by GPS (p=0.005) and functional selectivity score (p=0.049). In conclusion, ambulatory children with CP show adaptability in gait and are able to respond to real-time feedback, resulting in significant and clinically relevant improvements in peak hip and knee extension. These findings show the potential of real-time feedback as a tool for functional gait training and advanced gait analysis in CP. Copyright © 2016 Elsevier B.V. All rights reserved.

Policy makers have clearly indicated--through heavy investment in the Patient Centered Outcomes Research Institute--that reporting outcomes that are meaningful to patients is crucial for improvement in healthcare delivery and cost reduction. Better interpretation and generalizability of clinical research results that incorporate patient-centered outcomes research can be achieved by accelerating the development and uptake of core outcome sets (COS). COS provide a standardized minimum set of the outcomes that should be measured and reported in all clinical trials of a specific condition. The level of activity around COS has increased significantly over the past decade, with substantial progress in several clinical domains. However, there are many important clinical conditions for which high-quality COS have not been developed and there are limited resources and capacity with which to develop them. We believe that meaningful progress toward the goals behind the significant investments in patient-centered outcomes research and comparative effectiveness research will depend on a serious effort to address these issues.

Integrating clinical performance improvement across physician organizations: the PhyCor experience.

Loeppke, R; Howell, J W

1999-02-01

There is a paucity of literature describing the implementation of clinical performance improvement (CPI) efforts across geographically dispersed multispecialty group practices and independent practice associations. PhyCor, a physician management company based in Nashville, Tennessee, has integrated CPI initiatives into its operating infrastructure. PhyCor CPI INITIATIVES: The strategic framework guiding PhyCor's CPI initiatives is built around a physician-driven, patient-centered model. Physician/administrator leadership teams develop and implement a clinical and financial strategic plan for performance improvement; adopt local clinical and operational performance indicators; and agree on and gain consensus with local physician champions to engage in CPI initiatives. The area/regional leadership councils integrate and coordinate regional medical management and CPI initiatives among local groups and independent practice associations. In addition to these councils and a national leadership council, condition-specific care management councils have also been established. These councils develop condition-specific protocols and outcome measures and lead the implementation of CPI initiatives at their own clinics. Key resources supporting CPI initiatives include information/knowledge management, education and training, and patient education and consumer decision support. Localized efforts in both the asthma care and diabetes management initiatives have led to some preliminary improvements in quality of care indicators. Physician leadership and strategic vision, CPI-oriented organizational infrastructure, broad-based physician involvement in CPI, providing access to performance data, parallel incentives, and creating a sense of urgency for accelerated change are all critical success factors to the implementation of CPI strategies at the local, regional, and national levels.

Fourteen patients were examined one to four years after cricopharyngeal myotomy that had been carried out because of dysfunction of the pharyngo-esophageal sphincter. Twelve patients were examined radiologically. Eleven of the 14 patients were clinically improved or cured. In two patients who were not improved, the underlying condition was a polymyositis. The other patients suffered from an idiopathic dysfunction. Because of the small numbers involved, no detailed statistical analysis was carried out. Nevertheless, our results indicate that: Cricopharyngeus myotomy produces marked improvement or cure in patients with idiopathic dysfunction. Weak propulsive peristalsis of the pharyngeal constrictors is a prognostic factor indicating a poor clinical result of surgery. There is little chance of clinical improvement in patients with polymyositis.

Adults with Down syndrome (DS) represent a unique population who are in need of clinical guidelines to address their medical care. The United States Preventive Service Task Force (USPSTF) has developed criteria for prioritizing conditions of public health importance with the potential for providing screening recommendations to improve clinical care. The quality of existing evidence needed to inform clinical guidelines has not been previously reviewed. Using the National Library of Medicine (NLM) database PubMed, we first identified 18 peer reviewed articles that addressed co-occurring medical conditions in adults with DS. Those conditions discussed in over half of the articles were prioritized for further review. Second, we performed detailed literature searches on these specific conditions. To inform the search strategy and review process a series of key questions were formulated a priori. The quality of available evidence was then graded and knowledge gaps were identified. The number of participating adults and the design of clinical studies varied by condition and were often inadequate for answering all of our key questions. We provide data on thyroid disease, cervical spine disease, hearing impairment, overweight-obesity, sleep apnea, congenital heart disease, and osteopenia-osteoporosis. Minimal evidence demonstrates massive gaps in our clinical knowledge that compromises clinical decision-making and management of these medically complex individuals. The development of evidence-based clinical guidance will require an expanded clinical knowledge-base in order to move forward. © 2017 Wiley Periodicals, Inc.

Inherited retinal degenerations are a clinically and genetically heterogeneous group of conditions that have historically shared an untreatable course. In recent years, however, a wide range of therapeutic strategies have demonstrated efficacy in preclinical studies and entered clinical trials with a common goal of improving visual function for patients affected with these conditions. Gene therapy offers a particularly elegant and precise opportunity to target the causative genetic mutations underlying these monogenic diseases. The present review will provide an overview of gene therapy with particular emphasis on key clinical results to date and challenges for the future.

Placebo effect in clinical trial design for irritable bowel syndrome.

PubMed

Shah, Eric; Pimentel, Mark

2014-04-30

Ongoing efforts to improve clinical trial design in irritable bowel syndrome have been hindered by high placebo response rates and ineffective outcome measures. We assessed established strategies to minimize placebo effect as well as the various ap-proaches to placebo effect which can affect trial design. These include genetic markers such as catechol-O-methyltransferase, opioidergic and dopaminergic neurobiologic theory, pre-cebo effect centered on expectancy theory, and side effect unblinding grounded on conditioning theory. We reviewed endpoints used in the study of IBS over the past decade including adequate relief and subjective global relief, emphasizing their weaknesses in fully evaluating the IBS condition, specifically their motility effects based on functional net value and relative benefit-harm based on dropouts due to adverse events. The focus of this review is to highlight ongoing efforts to improve clinical trial design which can lead to better outcomes in a real-world setting.

Improved education in musculoskeletal conditions is necessary for all doctors.

Akesson, Kristina; Dreinhöfer, Karsten E.; Woolf, A. D.

2003-01-01

It is likely that everyone will, at some time, suffer from a problem related to the musculoskeletal system, ranging from a very common problem such as osteoarthritis or back pain to severely disabling limb trauma or rheumatoid arthritis. Many musculoskeletal problems are chronic conditions. The most common symptoms are pain and disability, with an impact not only on individuals' quality of life but also, importantly, on people's ability to earn a living and be independent. It has been estimated that one in four consultations in primary care is caused by problems of the musculoskeletal system and that these conditions may account for up to 60% of all disability pensions. In contrast, teaching at undergraduate and graduate levels--and the resulting competence and confidence of many doctors--do not reflect the impact of these conditions on individuals and society. Many medical students do not have any clinical training in assessing patients with bone and joint problems. Under the umbrella of the Bone and Joint Decade 2000-2010, experts from all parts of the world with an interest in teaching have developed recommendations for an undergraduate curriculum to improve the teaching of musculoskeletal conditions in medical schools. The goal for each medical school should be a course in musculoskeletal medicine concentrating on clinical assessment, common outpatient musculoskeletal problems and recognition of emergencies. Improving competency in the management of musculoskeletal problems within primary care settings through improved education is the next aim, but there are needs for improvement for all professionals and at all levels within the health care system.

Nurse-led clinics for atrial fibrillation: managing risk factors.

PubMed

Jacob, Liril

2017-12-14

Atrial fibrillation (AF) is the most common and sustained cardiac arrhythmia rated by cardiologists as one of the most difficult conditions to manage. Traditionally, AF management has focused on the three pillars of rate control, rhythm control and anticoagulation. However, more recently, cardiovascular risk-factor management in AF has emerged as a fourth and essential pillar, delivering improved patient outcomes. In the UK, AF is a condition that is often managed poorly, with patients reporting a lack of understanding of their condition and treatment options. Many aspects of assessment and communication in AF management are time consuming. Failure to address those aspects may negatively affect the quality of care. Nurse-led clinics can contribute significantly in the areas of patient education and sustained follow-up care, improving outcomes and addressing current deficiencies in AF risk-factor management due to scarcity of medical resources. This article discusses the major cardiovascular risk factors associated with AF, drawing on evidence from the literature, and considers the effectiveness and implications for practice of introducing community-based nurse-led clinics for risk-factor management in patients with AF.

Erosive Lichen Planus.

Mauskar, Melissa

2017-09-01

Lichen planus is an inflammatory mucocutaneous condition with a myriad of clinical manifestations. There are 3 forms of lichen planus that effect the vulva: papulosquamous, hypertrophic, and erosive. Erosive lichen planus can progress to vulvar scaring, vaginal stenosis, and squamous cell carcinoma; these long-term sequelae cause sexual distress, depression, and decreased quality of life for patients. Diagnosis is often delayed because of patient embarrassment or clinician misdiagnosis. Early recognition and treatment is essential to decreasing the morbidity of this condition. Multimodal treatment, along with a multidisciplinary approach, will improve outcomes and further clinical advances in studying this condition. Copyright © 2017 Elsevier Inc. All rights reserved.

Myette, Thomas L

2008-04-01

Depression is a chronic recurrent condition and is a leading cause of work disability. Improving occupational outcomes for depression will require an integrated approach that incorporates best practices from the clinical, community, and workplace systems. This article briefly reviews recent quality improvement initiatives and promising practices in each system and then shifts to the importance of systems integration. An integrated chronic care model uses a sophisticated case management process to support essential relationships, facilitate key plans, and efficiently link the three systems to optimize clinical, economic, and occupational outcomes. An expanded role for employers and their agents in the management of depression and other chronic diseases is seen as fundamental to maintaining a healthy and productive workforce. To improve occupational outcomes for depression by integrating best practices from the clinical, community, and workplace systems. After a brief review of quality improvement initiatives and promising practices in each system, an integrated chronic care model is introduced. A case management process that links critical systems, supports essential relationships, and facilitates key plans is expected to result in improvements in clinical, economic, and occupational outcomes. Employers should be more engaged with clinical and community partners in the prevention and control of depression in affected employees.

Influence of positive distractions on children in two clinic waiting areas.

Pati, Debajyoti; Nanda, Upali

2011-01-01

To examine the influence of positive distraction on the behavior and activity of children in two clinic waiting areas. People spend a considerable proportion of time waiting in hospitals. Studies show that the quality of waiting environments influences the perception of quality of care and caregivers, that perception of waiting time is a better indicator of patient satisfaction than actual waiting time, and that the waiting environment contributes to the perception of wait time. In fact, the attractiveness of the physical environment in waiting areas has been shown to be significantly associated with higher perceived quality of care, less anxiety, and higher reported positive interaction with staff. Can positive distractions in waiting areas improve the waiting experience, as indicated by the behavior and activities of children waiting for treatment? Five distraction conditions were randomly introduced in the waiting area of the dental and cardiac clinics of a major pediatric tertiary care center through a single plasma screen intervention. The attention, behavior, and activities of waiting children were recorded. Data on 158 pediatric patients were collected over 12 days during December 2008 and January 2009. Data analysis shows that the introduction of distraction conditions was associated with more calm behavior and less fine and gross movement, suggesting significant calming effects associated with the distraction conditions. Data also suggest that positive distraction conditions are significant attention grabbers and could be an important contributor to improving the waiting experience for children in hospitals by improving environmental attractiveness.

Clinical reasoning is an essential component of a health professional's practice. Yet clinical reasoning research has produced a notably fragmented body of literature. In this article, the authors describe the pause-and-reflect exercise they undertook during the execution of a synthesis of the literature on clinical reasoning in the health professions. Confronted with the challenge of establishing a shared understanding of the nature and relevant components of clinical reasoning, members of the review team paused to independently generate their own personal definitions and conceptualizations of the construct. Here, the authors describe the variability of definitions and conceptualizations of clinical reasoning present within their own team. Drawing on an analogy from mathematics, they hypothesize that the presence of differing "boundary conditions" could help explain individuals' differing conceptualizations of clinical reasoning and the fragmentation at play in the wider sphere of research on clinical reasoning. Specifically, boundary conditions refer to the practice of describing the conditions under which a given theory is expected to hold, or expected to have explanatory power. Given multiple theoretical frameworks, research methodologies, and assessment approaches contained within the clinical reasoning literature, different boundary conditions are likely at play. Open acknowledgment of different boundary conditions and explicit description of the conceptualization of clinical reasoning being adopted within a given study would improve research communication, support comprehensive approaches to teaching and assessing clinical reasoning, and perhaps encourage new collaborative partnerships among researchers who adopt different boundary conditions.Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a "work of the United States Government" for which copyright protection under Title 17 of the United States Code is not available.

Vascular Anomalies.

Taghinia, Amir H; Upton, Joseph

2018-06-12

Vascular anomalies encompass a wide variety of clinical conditions involving the vasculature. Over the past several decades, the terminology has changed as our understanding of these conditions has improved. A well-accepted classification scheme has evolved with constant additions, updates, and revisions. Imaging techniques have also advanced with greater resolution and a better understanding of the correlation between imaging, clinical behavior, and natural history. Meanwhile, the treatment of these conditions has also changed, with greater focus on minimally invasive techniques as opposed to radical surgery. Despite these changes, surgical intervention remains a high-value option for select patients. With greater understanding of the molecular basis of these diseases, medical treatment has improved especially in severe cases where options remain limited. A multidisciplinary approach to comprehensive patient care usually yields the best outcome and is strongly encouraged. Copyright © 2018 American Society for Surgery of the Hand.

The Importance of Conditional Probability in Diagnostic Reasoning and Clinical Decision Making: A Primer for the Eye Care Practitioner.

PubMed

Sanfilippo, Paul G; Hewitt, Alex W; Mackey, David A

2017-04-01

To outline and detail the importance of conditional probability in clinical decision making and discuss the various diagnostic measures eye care practitioners should be aware of in order to improve the scope of their clinical practice. We conducted a review of the importance of conditional probability in diagnostic testing for the eye care practitioner. Eye care practitioners use diagnostic tests on a daily basis to assist in clinical decision making and optimizing patient care and management. These tests provide probabilistic information that can enable the clinician to increase (or decrease) their level of certainty about the presence of a particular condition. While an understanding of the characteristics of diagnostic tests are essential to facilitate proper interpretation of test results and disease risk, many practitioners either confuse or misinterpret these measures. In the interests of their patients, practitioners should be aware of the basic concepts associated with diagnostic testing and the simple mathematical rule that underpins them. Importantly, the practitioner needs to recognize that the prevalence of a disease in the population greatly determines the clinical value of a diagnostic test.

The health-promoting short- and long-term effects of breast-feeding are supported by a vast scientific literature. The Bavarian prospective cohort study 2005/2006 showed regional variations of breast-feeding rates. Furthermore, improvement in counselling mothers, particularly with regard to prevention and handling of breast-feeding problems, has a great potential for health promotion. The objective of this study is to promote breast-feeding in maternity clinics by improving the surrounding conditions. A clinic-based and community-related intervention trial was carried out in Lower Bavaria as a model region with below average breast-feeding rates. (1) INTERVENTION: an advanced training of maternity ward professionals of 10 hospitals and after-care midwives was performed from May until December 2008. The training programme was based on the WHO/UNICEF criteria of the "Ten Steps to Successful Breastfeeding" to deepen the breast-feeding knowledge and to improve the breast-feeding management. (2) EVALUATION: A singular assessment of the advanced training programme was undertaken concerning an increase of knowledge and the practicability in clinical everyday life by participants; improvements of the maternity wards were assessed via structural interviews with maternity ward staff before and after intervention. Approximately 85% (n=378) of the staff of the 10 maternity clinics attended the training course. The survey after the training programme (response rate 83%) indicated that more than 80% of the participants stated to have learned something new and to be able to use the knowledge acquired for their own practice. Results of the clinic interviews showed a transfer of training contents into clinical work routines. Improvements at interview date were shown best for bonding (all 10 maternity clinics), for additional feeding (8 maternity clinics) as well as for 24-h rooming-in and mother counselling (7 maternal clinics each). Training of maternity ward professionals accounts for baby-friendly conditions in maternity clinics. Most willingness for improvements was shown by maternity ward staff particularly for bonding between mother and child as well as for additional feeding. Considerable differences between the hospitals were observed for the promotion of infant formulas before and after the intervention. © Georg Thieme Verlag KG Stuttgart · New York.

Polycystic ovary syndrome: a complex condition with psychological, reproductive and metabolic manifestations that impacts on health across the lifespan.

PubMed

Teede, H; Deeks, A; Moran, L

2010-06-30

Polycystic ovary syndrome (PCOS) is of clinical and public health importance as it is very common, affecting up to one in five women of reproductive age. It has significant and diverse clinical implications including reproductive (infertility, hyperandrogenism, hirsutism), metabolic (insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, adverse cardiovascular risk profiles) and psychological features (increased anxiety, depression and worsened quality of life). Polycystic ovary syndrome is a heterogeneous condition and, as such, clinical and research agendas are broad and involve many disciplines. The phenotype varies widely depending on life stage, genotype, ethnicity and environmental factors including lifestyle and bodyweight. Importantly, PCOS has unique interactions with the ever increasing obesity prevalence worldwide as obesity-induced insulin resistance significantly exacerbates all the features of PCOS. Furthermore, it has clinical implications across the lifespan and is relevant to related family members with an increased risk for metabolic conditions reported in first-degree relatives. Therapy should focus on both the short and long-term reproductive, metabolic and psychological features. Given the aetiological role of insulin resistance and the impact of obesity on both hyperinsulinaemia and hyperandrogenism, multidisciplinary lifestyle improvement aimed at normalising insulin resistance, improving androgen status and aiding weight management is recognised as a crucial initial treatment strategy. Modest weight loss of 5% to 10% of initial body weight has been demonstrated to improve many of the features of PCOS. Management should focus on support, education, addressing psychological factors and strongly emphasising healthy lifestyle with targeted medical therapy as required. Monitoring and management of long-term metabolic complications is also an important part of routine clinical care. Comprehensive evidence-based guidelines are needed to aid early diagnosis, appropriate investigation, regular screening and treatment of this common condition. Whilst reproductive features of PCOS are well recognised and are covered here, this review focuses primarily on the less appreciated cardiometabolic and psychological features of PCOS.

Abstract Objective To explore the barriers to and facilitators of adapting and expanding a primary care memory clinic model to integrate care of additional complex chronic geriatric conditions (heart failure, falls, chronic obstructive pulmonary disease, and frailty) into care processes with the goal of improving outcomes for seniors. Design Mixed-methods study using quantitative (questionnaires) and qualitative (interviews) methods. Setting Ontario. Participants Family physicians currently working in primary care memory clinic teams and supporting geriatric specialists. Methods Family physicians currently working in memory clinic teams (n = 29) and supporting geriatric specialists (n = 9) were recruited as survey participants. Interviews were conducted with memory clinic lead physicians (n = 16). Statistical analysis was done to assess differences between family physician ratings and geriatric specialist ratings related to the capacity for managing complex chronic geriatric conditions, the role of interprofessional collaboration within primary care, and funding and staffing to support geriatric care. Results from both study methods were compared to identify common findings. Main findings Results indicate overall support for expanding the memory clinic model to integrate care for other complex conditions. However, the current primary care structure is challenged to support optimal management of patients with multiple comorbidities, particularly as related to limited funding and staffing resources. Structured training, interprofessional teams, and an active role of geriatric specialists within primary care were identified as important facilitators. Conclusion The memory clinic model, as applied to other complex chronic geriatric conditions, has the potential to build capacity for high-quality primary care, improve health outcomes, promote efficient use of health care resources, and reduce health care costs.

An outcome series was conducted over a five-year period of patients attending a community NHS homeopathy clinic in Dorchester, Dorset. 273 new patients were seen. 183 (67%) questionnaires were completed at six months after initial consultation. 44% of patients had been unwell for more than five years; 19% of all patients for more than 15 years. A wide variety of conditions were seen, the largest group with depression, anxiety or grief. For follow-up patients 75-81% indicated an improvement in their symptoms and activity while 58% recorded an improvement in their overall wellbeing. Six months after the initiation of treatment 155 (84.7%) felt an improvement in their condition with 148 (81%) attributing this to homeopathy. Nobody reported deterioration due to homeopathic treatment; conventional drug use was reduced in 46 patients (25%). Copyright © 2011 The Faculty of Homeopathy. Published by Elsevier Ltd.

Best practice in the use of natalizumab in multiple sclerosis.

PubMed

Fernández, Oscar

2013-03-01

Natalizumab is approved for the treatment of patients with relapsing-remitting multiple sclerosis who have failed first-line treatment with traditional disease-modifying therapies or who have highly active disease. The drug has proved highly effective, both in a clinical trial setting and in clinical practice, with marked reductions in the rate of clinical relapses and slowed disease progression. These clinical outcomes are mirrored by a marked reduction in disease activity as evidenced by magnetic resonance imaging of the brain. However, natalizumab treatment has been associated with a risk of progressive multifocal leukoencephalopathy (PML), a potentially fatal condition caused by JC virus (JCV) activation. When this condition was detected in a clinical trial shortly after approval, the drug was immediately and voluntarily withdrawn from the market. As a condition of its reinstatement, stringent pharmacovigilance measures and a risk management plan were enforced. The recent availability of a two-step enzyme-linked immunosorbent assay (ELISA) test for the presence of anti-JCV antibodies (free testing is available in a central laboratory for registered centers), along with an ever-improving understanding of other risk factors such as prior immunosuppressant use and duration of treatment, allow an increasingly refined stratification of the risk of PML. This improved stratification of risk can help guide decisions about treatment. This review will also deal with other topics of relevance to clinical practice such as the development of antinatalizumab antibodies and their negative implications in terms of hypersensitivity reactions and loss of efficacy, withdrawal of treatment, and compassionate pediatric use.

Medicare's fee-for-service (FFS) payment model may contribute to unsustainable spending growth. Payers are turning to alternative payment methods. The leading alternative payment model to the FFS problem is bundled payment. The Centers for Medicare & Medicaid Services (CMS) is taking another step to improve healthcare quality at lower cost. The CMS's Center for Medicare and Medicaid Innovation developed four models of bundled payments and 48 discrete clinical condition episodes. Many surgical care procedures are included in the 48 different clinical condition episodes.

The purpose of the study was to assess the effectiveness and safety of long-term application of fenspiride, an anti-inflammatory drug, in patients with chronic obstructive pulmonary disease (COPD) under outpatient conditions. The drug was studied on 24 COPD patients. Fenspiride application resulted in improvement in bronchoobstructive syndrome and external respiration parameters, as well as a significant increase in exercise tolerance. In patients with stable stage I COPD, the use of fenspiride as a part of therapeutic regimen leads to better clinical results than in stage II patients. Long-term application of fenspiride in medium therapeutic doses under outpatient conditions is associated with positive clinical effects and leads to significant improvement in quality of life.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a chronic pelvic pain condition largely refractory to treatment. Cannabis (marijuana) use has been reported for a wide variety of chronic pain conditions, but no study has examined prevalence of cannabis use, symptom benefit or side effects, or frequency in CP/CPPS. Participants were recruited from an outpatient CP/CPPS urology clinic (n = 98) and online through the Prostatitis Foundation website (n = 244). Participants completed questionnaires (demographics, CP/CPPS, depression, cannabis). The clinic sample included Canadian patients and the online sample included primarily American patients. Due to differences, groups were examined separately. Almost 50% of respondents reported using cannabis (clinic n = 49; online n = 89). Of the cannabis users, 36.8% of clinic and 75% of online respondents reported that it improved their symptoms. Most of the respondents (from the clinic and online groups) reported that cannabis improved their mood, pain, muscle spasms, and sleep. However, they did not note any improvements for weakness, fatigue, numbness, ambulation, and urination. Overall, the effectiveness of cannabis for CP/CPPS was "somewhat/very effective" (57% clinic; 63% online). There were no differences between side effects or choice of consumption and most reported using cannabis rarely. These are the first estimates in men suffering from CP/CPPS and suggest that while cannabis use is prevalent, its medical use and benefit are unknown. This is an understudied area and the benefit or hazard for cannabis use awaits further study.

To investigate the effects of Methylphenidate (MPH) on postural stability in attention deficit hyperactivity disorder (ADHD) children in single and dual task conditions. A randomized controlled double-blind study analyzing postural stability in 24 ADHD children before and after MPH vs. placebo treatments, in three task conditions: (1) Single task, standing still; (2) dual task, standing still performing a memory-attention demanding task; (3) standing still listening to music. MPH resulted in a significant improvement in postural stability during the dual task condition and while listening to music, with no equivalent improvement in placebo controls. MPH improves postural stability in ADHD, especially when an additional task is performed. This is probably due to enhanced attention abilities, thus contributing to improved balance control during performance of tasks that require attention. MPH remains to be studied as a potential drug treatment to improve balance control and physical functioning in other clinical populations.

Decision support tools increasingly integrate clinical knowledge such as medication indications and contraindications with electronic health record (EHR) data to support clinical care and patient safety. The availability of this encoded information and patient data provides an opportunity to develop measures of clinical decision complexity that may be of value for quality improvement and research efforts. We investigated the feasibility of using encoded clinical knowledge and EHR data to develop a measure of comorbidity interrelatedness (the degree to which patients' co-occurring conditions interact to generate clinical complexity). Using a common clinical scenario-decisions about blood pressure medications in patients with hypertension-we quantified comorbidity interrelatedness by calculating the number of indications and contraindications to blood pressure medications that are generated by patients' comorbidities (e.g., diabetes, gout, depression). We examined properties of comorbidity interrelatedness using data from a decision support system for hypertension in the Veterans Affairs Health Care System.

The obstetrics/gynecology department of York Hospital (York Health System, York, Pennsylvania) initiated a program to improve the processes of care and control costs for common women's and newborns' health care services. Twelve clinical policies were established between June 1993 and February 1995. CONDUCTING THE QUALITY IMPROVEMENT (QI) PROJECTS: Using the plan-do-check-act (PDCA) improvement cycle method, the QI group established clinical pathways for high-volume conditions or procedures known to have low rates of complications and clinical guidelines for those conditions or procedures not requiring coordinated efforts of a group of health care professionals. EXAMPLE--PYELONEPHRITIS IN PREGNANCY: The literature had indicated that the prevalence of pyelonephritis can be decreased by identifying and treating asymptomatic bacteriuria early in prenatal care. After the validity of the clinical policy was demonstrated in the resident service, the policy was extended to all private obstetric practices. Dissemination of the finding that most of the admissions for pyelonephritis were for referred patients (for whom we had no control over prenatal care) or for patients referred by private physicians who were not yet following the guidelines quickly led to complete compliance by our obstetricians and other health care providers referring patients to the York Health System. The 12 clinical policies resulted in the elimination of 113 admissions and 5,595 inpatient days and in the reduction of the cost of patient care by $1,306,214 for the years 1994-1995 and 1995-1996 combined, without apparent adverse effects on patient health. A voluntary clinical policies program can change the culture of a department and lead to cost-effectiveness and better quality of patient care.

Is secondary preventive care improving? Observational study of 10-year trends in emergency admissions for conditions amenable to ambulatory care

2013-01-01

Objective To identify trends in emergency admissions for patients with clinical conditions classed as ‘ambulatory care sensitive’ (ACS) and assess if reductions might be due to improvements in preventive care. Design Observational study of routinely collected hospital admission data from March 2001 to April 2011. Admission rates were calculated at the population level using national population estimates for area of residence. Participants All emergency admissions to National Health Service (NHS) hospitals in England from April 2001 to March 2011 for people residents in England. Main outcome measures Age-standardised emergency admissions rates for each of 27 specific ACS conditions (ICD-10 codes recorded as primary or secondary diagnoses). Results Between April 2001 and March 2011 the number of admissions for ACS conditions increased by 40%. When ACS conditions were defined solely on primary diagnosis, the increase was less at 35% and similar to the increase in emergency admissions for non-ACS conditions. Age-standardised rates of emergency admission for ACS conditions had increased by 25%, and there were notable variations by age group and by individual condition. Overall, the greatest increases were for urinary tract infection, pyelonephritis, pneumonia, gastroenteritis and chronic obstructive pulmonary disease. There were significant reductions in emergency admission rates for angina, perforated ulcers and pelvic inflammatory diseases but the scale of these successes was relatively small. Conclusions Increases in rates of emergency admissions suggest that efforts to improve the preventive management of certain clinical conditions have failed to reduce the demand for emergency care. Tackling the demand for hospital care needs more radical approaches than those adopted hitherto if reductions in emergency admission rates for ACS conditions overall are to be seen as a positive outcome of for NHS.

To examine the prevalence of potentially reversible conditions in dementia and mild cognitive impairment (MCI) patients in a geriatric clinic. We retrospectively reviewed the medical records of patients who attended the outpatient geriatric clinic at Siriraj Hospital, Bangkok between January 2005 and December 2010. We collected the data regarding potentially reversible conditions of cognitive impairment. There were 233 patients newly diagnosed with dementia and 60 patients diagnosed with MCI. We found potentially reversible causes of dementia in 17 patients (7.3%). The causes were hypothyroidism (2.6%), B12 deficiency (1.7%), normal pressure hydrocephalus (NPH) (0.9%), depression (0.9%), folate deficiency (0.4%), reactive Venereal Disease Research Laboratory (VDRL; 0.4%) and chronic subdural hematoma (CSH; 0.4%). The patients with NPH and CSH were clinically suspicious for having such conditions before the investigations, while patients with low B12 level, low folate level, hypothyroidism and VDRL+ were not. In the MCI group, we found potentially reversible causes in two patients (3.3%), these were B12 deficiency (1.7%) and hypothyroidism (1.7%). Clinical improvement after treatment of the potentially reversible conditions was seen in four patients (one NPH, one subdural hematoma and two with depression) in dementia group (1.7%) and none in the MCI group. All were partially reversed. Routine investigations might be more warranted for metabolic conditions (B12 level and hypothyroidism) as clinical presentations are not suggestive of the conditions. However, reversibility of dementia might not occur in these cases. Neuroimaging should be performed selectively as clinically indicated. Truly reversible conditions are rare and occur in surgical and depressive patients. © 2011 Japan Geriatrics Society.

To measure the impact of a diabetes and cardiovascular risk factors program implemented in a social security institution upon short- and long-term clinical/metabolic outcomes and costs of care. Observational longitudinal cohort analysis of clinical/metabolic data and resource use of 300 adult male and female program participants with diabetes before (baseline) and 1 and 3 years after implementation of the program. Data were obtained from clinical records (Qualidiab) and the administration's database. The implementation of the program in "real world" conditions resulted in an immediate and sustainable improvement of the quality of care provided to people with diabetes incorporated therein. We also recorded a more appropriate oral therapy prescription for hyperglycemia and cardiovascular risk factors (CVRFs), as well as a decrease of events related to chronic complications. This improvement was associated with an increased use of diagnostic and therapeutic resources, particularly those related to pharmacy prescriptions, not specifically used for the control of hyperglycemia and other CVRFs. The implementation of a diabetes program in real-world conditions results in a significant short- and long-term improvement of the quality of care provided to people with diabetes and other CVRFs, but simultaneously increased the use of resources and the cost of diagnostic and therapeutic practices. Since controlled studies have shown improvement in quality of care without increasing costs, our results suggest the need to include management-control strategies in these programs for appropriate medical and administrative feedback to ensure the simultaneous improvement of clinical outcomes and optimization of the use of resources.

Objective The present study evaluated three technology-based methods of training mental health providers in exposure therapy (ET) for anxiety disorders. Training methods were designed to address common barriers to the dissemination of ET, including limited access to training, negative clinician attitudes toward ET, and lack of support during and following training. Method Clinicians naïve to ET (N=181, Mage = 37.4, 71.3% female, 72.1% Caucasian) were randomly assigned to: 1) an interactive, multimedia online training (OLT), 2) OLT plus a brief, computerized motivational enhancement intervention (OLT+ME), or 3) OLT + ME plus a web-based learning community (OLT+ME+LC). Assessments were completed at baseline, post-training, and 6 and 12 weeks following training. Outcomes include satisfaction, knowledge, self-efficacy, attitudes, self-reported clinical use, and observer-rated clinical proficiency. Results All three training methods led to large and comparable improvements in self-efficacy and clinical use of ET, indicating that OLT alone was sufficient for improving these outcomes. The addition of the ME intervention did not significantly improve outcomes in comparison to OLT alone. Supplementing the OLT with both the ME intervention and the LC significantly improved attitudes and clinical proficiency in comparison to OLT alone. The OLT+ME+LC condition was superior to both other conditions in increasing knowledge of ET. Conclusions Multi-component trainings that address multiple potential barriers to dissemination appear to be most effective in improving clinician outcomes. Technology-based training methods offer a satisfactory, effective, and scalable way to train mental health providers in evidence-based treatments such as ET. PMID:25311284

Cystic fibrosis (CF) patients present an altered fatty acid (FA) metabolism characterized by imbalance in the arachidonic/docosohexasenoic acid (AA/DHA) ratio in favour of the former which can contribute to the increase in pulmonary inflammation. The present study aims to assess respiratory, nutritional, clinical and laboratory parameters, and inflammatory markers after six months of DHA supplementation in paediatric patients suffering from CF. A dose of 1 g/10 kg/die was administered to ten CF patients of paediatric age for the first month and 250 mg/10 kg/die for the remaining 5 months. We carried out follow-ups at T0 (baseline), T6 (after six months of the diet) and T12 (six months after supplementation was interrupted) during which respiratory, nutritional, clinical and laboratory parameters were assessed. After six months of DHA supplementation inflammatory marker levels had diminished: interleukin 8 (IL-8) and Tumour Necrosis Factor Alfa (TNF-α) in serum, and calprotectin in stools. In addition, auxometric parameters were improved as was the clinical condition of patients, who tolerated DHA well. Dietetic integration with DHA seems to improve clinical condition and the inflammatory pulmonary and intestinal state of pediatric patients suffering from CF.

Clinical coordination is considered a health policy priority as its absence can lead to poor quality of care and inefficiency. A key challenge is to identify which strategies should be implemented to improve coordination. The aim is to analyse doctors' opinions on the contribution of mechanisms to improving clinical coordination between primary and outpatient secondary care and the factors influencing their use. A qualitative descriptive study in three healthcare networks of the Catalan national health system. A two-stage theoretical sample was designed: in the first stage, networks with different management models were selected; in the second, primary care (n = 26) and secondary care (n = 24) doctors. Data were collected using semi-structured interviews. Final sample size was reached by saturation. A thematic content analysis was conducted, segmented by network and care level. With few differences across networks, doctors identified similar mechanisms contributing to clinical coordination: 1) shared EMR facilitating clinical information transfer and uptake; 2) mechanisms enabling problem-solving communication and agreement on clinical approaches, which varied across networks (joint clinical case conferences, which also promote mutual knowledge and training of primary care doctors; virtual consultations through EMR and email); and 3) referral protocols and use of the telephone facilitating access to secondary care after referrals. Doctors identified organizational (insufficient time, incompatible timetables, design of mechanisms) and professional factors (knowing each other, attitude towards collaboration, concerns over misdiagnosis) that influence the use of mechanisms. Mechanisms that most contribute to clinical coordination are feedback mechanisms, that is those based on mutual adjustment, that allow doctors to exchange information and communicate. Their use might be enhanced by focusing on adequate working conditions, mechanism design and creating conditions that promote mutual knowledge and positive attitudes towards collaboration.

Strong evidence suggests that patient-reported outcomes (PROs) aid in managing chronic conditions, reduce omissions in care, and improve patient-provider communication. However, provider acceptability of PROs and their use in clinical HIV care is not well known. We interviewed providers (n=27) from four geographically diverse HIV and community care clinics in the U.S. that have integrated PROs into routine HIV care, querying perceived value, challenges, and use of PRO data. Perceived benefits included the ability of PROs to identify less-observable behaviors and conditions, particularly suicidal ideation, depression, and substance use; usefulness in agenda-setting prior to a visit; and reduction of social desirability bias in patient-provider communication. Challenges included initial flow integration issues and ease of interpretation of PRO feedback. Providers value same-day, electronic patient-reported measures for use in clinical HIV care with the condition that PROs are 1) tailored to be the most clinically relevant to their population; 2) well-integrated into clinic flow; 3) easy to interpret, highlighting chief patient concerns and changes over time.

Systemic amyloidosis: novel therapies and role of biomarkers.

PubMed

Nuvolone, Mario; Merlini, Giampaolo

2017-05-01

Systemic amyloidosis is caused by misfolding and extracellular deposition of one of an ever-growing list of circulating proteins, resulting in vital organ dysfunction and eventually death. Despite different predisposing conditions, including plasma cell dyscrasias [immunoglobulin light chain (AL) amyloidosis], long-lasting inflammation [reactive (AA) amyloidosis] or mutations (hereditary amyloidoses), clinical manifestations are conspicuously overlapping and mimic more prevalent conditions, significantly complicating and often delaying the recognition of these rare, complex diseases. However, refined diagnostic and imaging approaches and the increasing role of biomarkers, which help in establishing the diagnosis, assessing the prognosis and evaluating the response to therapy, have considerably improved the management of these conditions. The pillar of anti-amyloid therapy remains the prompt reduction or elimination of the amyloidogenic precursor. This is accomplished by targeting the underlying condition, and recent improvements in the treatment of plasma cell disorders and chronic inflammatory conditions have positively reverberated onto the management of AL and AA amyloidosis, respectively. Moreover, recent, substantial improvements in the understanding of the molecular underpinnings of systemic amyloidosis have unveiled different key steps in the amyloidogenic cascade which can be valid therapeutic targets. These include stabilizers of the native conformation of the amyloidogenic precursor, inhibitors of fibrillogenesis, amyloid fibril disruptors and promoters of amyloid clearance. Innovative pharmacological strategies, including rational, structure-based drug design, gene knockdown and immunotherapy, but also repurposing of old, safe drugs with newly recognized anti-amyloid properties, are currently being pursued already in the clinical setting, holding the promise of dramatically improving the outcome of these dismal conditions in the near future. © The Author 2016.

2017-01-01

We present a case of severe acquired acrodermatitis enteropathica in a vegan adult female with multiple underlying comorbidities. Acquired acrodermatitis enteropathica or zinc-deficiency dermatitis is the most common diagnosis than many practitioners realize with up to 10% of the patients in developed nations with the risk of zinc deficiency. The condition can be difficult to diagnose due to many similarly-presenting conditions. Furthermore, comorbid conditions in the patients can serve as confounders to the diagnosis. The symptoms are often extremely distressing for the patients, though the treatment is simple and clinical improvement occurs rapidly with appropriate care. We recommend a high index of suspicion to practitioners as well as a low-threshold for initiating treatment in the patients with any clinical symptoms of the condition. PMID:29152424

The National Health and Family Planning Commission of China has issued more than 400 clinical pathways to improve the effectiveness and efficiency of medical care delivered by public hospitals in China. The aim of our study is to determine whether patient care is compliant with national clinical pathways in public general hospitals of Pudong New Area in Shanghai. We identified the clinical pathways established by the National Health and Family Planning Commission of China for 5 common conditions (community-acquired pneumonia, acute myocardial infarction (AMI), heart failure, cesarean section, type-2 diabetes). We randomly selected patients with each condition admitted to one of 7 public general hospitals in Pudong New Area in China in January, 2013. We identified key process indicators (KPIs) for each pathway and, based on chart review for each patient, determined whether the patient's care was compliant for each indicator. We calculated the proportion of care which was compliant with clinical pathways for each indicator, the average proportion of indicators that were met for each patient, and the proportion of patients whose care was compliant for all measures. For selected indicators, we compared compliance rates among hospitals in our study with those from other countries. Average compliance rates across the KPIs for each condition ranged from 61 % for AMI to 89 % for pneumonia. The percent of patient receiving fully compliant care ranged from 0 for AMI and heart failure to 39 % for pneumonia. Compared to the compliance rate for process indicators in the hospitals of other countries, some rates in the hospitals that we audited were higher, but some were lower. Few patients received care that complied with all the pathways for each condition. The reasons for low compliance with national clinical pathways and how to improve clinical quality in public hospitals of China need to be further explored.

The ultimate goal of Fontan surgical planning is to provide additional insights into the clinical decision-making process. In its current state, surgical planning offers an accurate hemodynamic assessment of the pre-operative condition, provides anatomical constraints for potential surgical options, and produces decent post-operative predictions if boundary conditions are similar enough between the pre-operative and post-operative states. Moving forward, validation with post-operative data is a necessary step in order to assess the accuracy of surgical planning and determine which methodological improvements are needed. Future efforts to automate the surgical planning process will reduce the individual expertise needed and encourage use in the clinic by clinicians. As post-operative physiologic predictions improve, Fontan surgical planning will become an more effective tool to accurately model patient-specific hemodynamics.

The pending workforce crisis in family medicine has triggered various initiatives. This article describes the PMU-FLON walk-in clinic, a project of the Institute of General Medicine University of Lausanne. The working conditions in this clinic are close to that of a family practice. Doctors in training are supervised by family doctors who work part-time in the clinic. The objective is to improve training in the various fields of family medicine, from technical skills (improving optimal use of diagnostic tools), to integrating patients' requests in a more global patient-centered approach. This new educational model allows doctors in training to benefit from the specific approaches of different trainers. It will contribute to promoting quality family medicine in the future.

A "client perspective" helps improve services.

PubMed

1998-01-01

Egypt's Ministry of Health launched a campaign in 1992 to improve client satisfaction with family planning clinic services in the country. In the program, family planning clinic supervisors are being trained to use a checklist of 101 indicators to evaluate services, ranging from the availability of contraceptive commodities to the condition of facilities. Television messages and posters disseminated throughout communities instruct potential clients to look for gold stars on the doors of family planning clinics across the country, indicators of a clinic which meets quality service standards. This program is currently used by almost 4000 clinics nationwide. Family planning services worldwide have long focused upon increasing levels of contraceptive use. More recently, however, they are also focusing upon the quality of services provided. Frameworks for improving services tend to emphasize better ways to interact with clients, and often address how to approach specific management concerns, such as maintaining adequate contraceptive supplies. Client interaction, management concerns, and how quality makes a difference are discussed.

Bionic devices electrically activate neural populations to partially restore lost function. Of fundamental importance is the functional integrity of the targeted neurons. However, in many conditions the ongoing pathology can lead to continued neural degeneration and death that may compromise the effectiveness of the device and limit future strategies to improve performance. The use of drugs that can prevent nerve cell degeneration and promote their regeneration may improve clinical outcomes. In this paper we focus on strategies of delivering neuroprotective drugs to the auditory system in a way that is safe and clinically relevant for use in combination with a cochlear implant. The aim of this approach is to prevent neural degeneration and promote nerve regrowth in order to improve outcomes for cochlear implant recipients using techniques that can be translated to the clinic.

Best practice in the use of natalizumab in multiple sclerosis

PubMed Central

2013-01-01

Natalizumab is approved for the treatment of patients with relapsing–remitting multiple sclerosis who have failed first-line treatment with traditional disease-modifying therapies or who have highly active disease. The drug has proved highly effective, both in a clinical trial setting and in clinical practice, with marked reductions in the rate of clinical relapses and slowed disease progression. These clinical outcomes are mirrored by a marked reduction in disease activity as evidenced by magnetic resonance imaging of the brain. However, natalizumab treatment has been associated with a risk of progressive multifocal leukoencephalopathy (PML), a potentially fatal condition caused by JC virus (JCV) activation. When this condition was detected in a clinical trial shortly after approval, the drug was immediately and voluntarily withdrawn from the market. As a condition of its reinstatement, stringent pharmacovigilance measures and a risk management plan were enforced. The recent availability of a two-step enzyme-linked immunosorbent assay (ELISA) test for the presence of anti-JCV antibodies (free testing is available in a central laboratory for registered centers), along with an ever-improving understanding of other risk factors such as prior immunosuppressant use and duration of treatment, allow an increasingly refined stratification of the risk of PML. This improved stratification of risk can help guide decisions about treatment. This review will also deal with other topics of relevance to clinical practice such as the development of antinatalizumab antibodies and their negative implications in terms of hypersensitivity reactions and loss of efficacy, withdrawal of treatment, and compassionate pediatric use.

TH-EF-BRA-03: Assessment of Data-Driven Respiratory Motion-Compensation Methods for 4D-CBCT Image Registration and Reconstruction Using Clinical Datasets

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

Riblett, MJ; Weiss, E; Hugo, GD

Purpose: To evaluate the performance of a 4D-CBCT registration and reconstruction method that corrects for respiratory motion and enhances image quality under clinically relevant conditions. Methods: Building on previous work, which tested feasibility of a motion-compensation workflow using image datasets superior to clinical acquisitions, this study assesses workflow performance under clinical conditions in terms of image quality improvement. Evaluated workflows utilized a combination of groupwise deformable image registration (DIR) and image reconstruction. Four-dimensional cone beam CT (4D-CBCT) FDK reconstructions were registered to either mean or respiratory phase reference frame images to model respiratory motion. The resulting 4D transformation was usedmore » to deform projection data during the FDK backprojection operation to create a motion-compensated reconstruction. To simulate clinically realistic conditions, superior quality projection datasets were sampled using a phase-binned striding method. Tissue interface sharpness (TIS) was defined as the slope of a sigmoid curve fit to the lung-diaphragm boundary or to the carina tissue-airway boundary when no diaphragm was discernable. Image quality improvement was assessed in 19 clinical cases by evaluating mitigation of view-aliasing artifacts, tissue interface sharpness recovery, and noise reduction. Results: For clinical datasets, evaluated average TIS recovery relative to base 4D-CBCT reconstructions was observed to be 87% using fixed-frame registration alone; 87% using fixed-frame with motion-compensated reconstruction; 92% using mean-frame registration alone; and 90% using mean-frame with motion-compensated reconstruction. Soft tissue noise was reduced on average by 43% and 44% for the fixed-frame registration and registration with motion-compensation methods, respectively, and by 40% and 42% for the corresponding mean-frame methods. Considerable reductions in view aliasing artifacts were observed for each method. Conclusion: Data-driven groupwise registration and motion-compensated reconstruction have the potential to improve the quality of 4D-CBCT images acquired under clinical conditions. For clinical image datasets, the addition of motion compensation after groupwise registration visibly reduced artifact impact.

The cost to build and to maintain traditional registries for many dire, complex, low-frequency conditions is prohibitive. The authors used accessible technology to develop a platform that would generate miniregistries (small, routinely updated datasets) for surveillance, to identify patients who were missing elected utilization and to influence clinicians to change practices to improve care. The platform, tested in 5 medical specialty departments, enabled the specialists to rapidly and effectively communicate clinical questions, knowledge of disease, clinical workflows, and improve opportunities. Each miniregistry required 1 to 2 hours of collaboration by a specialist. Turnaround was 1 to 14 days.

Public health nurses (PHNs) working in Well Baby Clinic in Israel's Haifa district were voicing great distress to inspectors-the impossibility of meeting their workload, feeling overwhelmed, poor physical, and technological conditions. They were feeling tired and frustrated and burn-out was rising. The district's nursing management took the decision, together with Tel Aviv University's nursing research unit, to conduct a quality improvement project based on issues that arose from meetings with focus groups on the nurses' difficulties. This paper is a case study of a quality improvement project targeting nurses daily working life. One of its chief contributions is as a study of meeting PHNs' frustration by integrating focus groups and round-table brainstorming (involving nurses, clinic managers and nursing inspectors) in order to identify targets for practical intervention. This strategy has been very successful. It has provided the district's nursing management a battery of forcefully argued and realistically grounded proposals for making the work of Well Baby clinics more relevant to their communities and giving nurses (a) the conditions to meet their assignments and (b) greater professional self-respect. © 2016 Wiley Periodicals, Inc.

ASSESSING REFERRALS AND IMPROVING INFORMATION AVAILABILITY FOR CONSULTATIONS IN AN ACADEMIC ENDOCRINOLOGY CLINIC.

2017-02-01

Outpatient specialty consultations rely on the timeliness and completeness of referral information to facilitate a valuable patient-specialist interaction. This project aimed to increase essential diagnostic information availability at the initial consultation for patients referred for common endocrine conditions frequently lacking such data-diabetes mellitus, thyroid nodule, thyrotoxicosis, and hypercalcemia. At an endocrinology clinic at an academic medical center in rural New England, providers see several thousand new patients annually, the majority of whom are referred by providers external to the clinic's healthcare system. Through consensus, endocrinology clinic providers agreed on the two or three data elements essential for a meaningful initial consultation for each. A quality improvement team employed a planned series of interventions based on previously published methods and an innovative approach: dissemination of a referral guideline, an assessment of referral adequacy in the endocrinology clinic workflow, coupled with focused requests for missing items, and a pre-visit lab appointment. Between April 2015 and March 2016, 762 referrals were reviewed. At baseline for the four conditions, referrals contained all essential elements only 27.5% (22 of 80) of the time. Over a 7-month period, the team implemented the interventions, with subsequent referrals containing all essential elements increasing to 75.5% (P<.0001), largely attributable to the pre-visit lab appointment. Incoming referrals that lack essential information are a significant problem in specialty care and may adversely affect patient experience, provider satisfaction, and clinic efficiency. Improvement may require innovative approaches, such as the potentially transferable and generalizable ones employed here.

Chandakkar, Parag S.; Venkatesan, Ragav; Li, Baoxin

2013-02-01

Diabetic retinopathy (DR) is a vision-threatening complication from diabetes mellitus, a medical condition that is rising globally. Unfortunately, many patients are unaware of this complication because of absence of symptoms. Regular screening of DR is necessary to detect the condition for timely treatment. Content-based image retrieval, using archived and diagnosed fundus (retinal) camera DR images can improve screening efficiency of DR. This content-based image retrieval study focuses on two DR clinical findings, microaneurysm and neovascularization, which are clinical signs of non-proliferative and proliferative diabetic retinopathy. The authors propose a multi-class multiple-instance image retrieval framework which deploys a modified color correlogram and statistics of steerable Gaussian Filter responses, for retrieving clinically relevant images from a database of DR fundus image database.

How good is "evidence" from clinical studies of drug effects and why might such evidence fail in the prediction of the clinical utility of drugs?

PubMed

Naci, Huseyin; Ioannidis, John P A

2015-01-01

Promising evidence from clinical studies of drug effects does not always translate to improvements in patient outcomes. In this review, we discuss why early evidence is often ill suited to the task of predicting the clinical utility of drugs. The current gap between initially described drug effects and their subsequent clinical utility results from deficits in the design, conduct, analysis, reporting, and synthesis of clinical studies-often creating conditions that generate favorable, but ultimately incorrect, conclusions regarding drug effects. There are potential solutions that could improve the relevance of clinical evidence in predicting the real-world effectiveness of drugs. What is needed is a new emphasis on clinical utility, with nonconflicted entities playing a greater role in the generation, synthesis, and interpretation of clinical evidence. Clinical studies should adopt strong design features, reflect clinical practice, and evaluate outcomes and comparisons that are meaningful to patients. Transformative changes to the research agenda may generate more meaningful and accurate evidence on drug effects to guide clinical decision making.

Background Young people (aged 16-24 years) with long-term health conditions can disengage from health services, resulting in poor health outcomes, but clinicians in the UK National Health Service (NHS) are using digital communication to try to improve engagement. Evidence of effectiveness of this digital communication is equivocal. There are gaps in evidence as to how it might work, its cost, and ethical and safety issues. Objective Our objective was to understand how the use of digital communication between young people with long-term conditions and their NHS specialist clinicians changes engagement of the young people with their health care; and to identify costs and necessary safeguards. Methods We conducted mixed-methods case studies of 20 NHS specialist clinical teams from across England and Wales and their practice providing care for 13 different long-term physical or mental health conditions. We observed 79 clinical team members and interviewed 165 young people aged 16-24 years with a long-term health condition recruited via case study clinical teams, 173 clinical team members, and 16 information governance specialists from study NHS Trusts. We conducted a thematic analysis of how digital communication works, and analyzed ethics, safety and governance, and annual direct costs. Results Young people and their clinical teams variously used mobile phone calls, text messages, email, and voice over Internet protocol. Length of clinician use of digital communication varied from 1 to 13 years in 17 case studies, and was being considered in 3. Digital communication enables timely access for young people to the right clinician at the time when it can make a difference to how they manage their health condition. This is valued as an addition to traditional clinic appointments and can engage those otherwise disengaged, particularly at times of change for young people. It can enhance patient autonomy, empowerment and activation. It challenges the nature and boundaries of therapeutic relationships but can improve trust. The clinical teams studied had not themselves formally evaluated the impact of their intervention. Staff time is the main cost driver, but offsetting savings are likely elsewhere in the health service. Risks include increased dependence on clinicians, inadvertent disclosure of confidential information, and communication failures, which are mostly mitigated by young people and clinicians using common-sense approaches. Conclusions As NHS policy prompts more widespread use of digital communication to improve the health care experience, our findings suggest that benefit is most likely, and harms are mitigated, when digital communication is used with patients who already have a relationship of trust with the clinical team, and where there is identifiable need for patients to have flexible access, such as when transitioning between services, treatments, or lived context. Clinical teams need a proactive approach to ethics, governance, and patient safety. PMID:28396301

Probabilistic techniques for obtaining accurate patient counts in Clinical Data Warehouses

Myers, Risa B.; Herskovic, Jorge R.

2011-01-01

Proposal and execution of clinical trials, computation of quality measures and discovery of correlation between medical phenomena are all applications where an accurate count of patients is needed. However, existing sources of this type of patient information, including Clinical Data Warehouses (CDW) may be incomplete or inaccurate. This research explores applying probabilistic techniques, supported by the MayBMS probabilistic database, to obtain accurate patient counts from a clinical data warehouse containing synthetic patient data. We present a synthetic clinical data warehouse (CDW), and populate it with simulated data using a custom patient data generation engine. We then implement, evaluate and compare different techniques for obtaining patients counts. We model billing as a test for the presence of a condition. We compute billing’s sensitivity and specificity both by conducting a “Simulated Expert Review” where a representative sample of records are reviewed and labeled by experts, and by obtaining the ground truth for every record. We compute the posterior probability of a patient having a condition through a “Bayesian Chain”, using Bayes’ Theorem to calculate the probability of a patient having a condition after each visit. The second method is a “one-shot” approach that computes the probability of a patient having a condition based on whether the patient is ever billed for the condition Our results demonstrate the utility of probabilistic approaches, which improve on the accuracy of raw counts. In particular, the simulated review paired with a single application of Bayes’ Theorem produces the best results, with an average error rate of 2.1% compared to 43.7% for the straightforward billing counts. Overall, this research demonstrates that Bayesian probabilistic approaches improve patient counts on simulated patient populations. We believe that total patient counts based on billing data are one of the many possible applications of our Bayesian framework. Use of these probabilistic techniques will enable more accurate patient counts and better results for applications requiring this metric. PMID:21986292

Vinpocetine Improves Scopolamine Induced Learning and Memory Dysfunction in C57 BL/6J Mice.

Vinpocetine is an inhibitor of phosphodiesterase type 1 (PDE1), which has been used for treating stroke for over 40 years. However, according to current clinical dosage and treatment period, its direct effect on memory is unclear. In this study, we investigated whether vinpocetine could reverse the scopolamine (SCO)-induced cognitive deficits in animals. Behavioral experiments, including open field, Y-maze, and fear conditioning tests were used to determine the possible role of vinpocetine on scopolamine-induced memory dysfunction. In the open field and Y-maze tests, there were significant differences between the control (CON) group and SCO group. Vinpocetine (4 mg/kg) administration for consecutive 28 d significantly improved the scopolamine-induced memory dysfunction. In the fear conditioning test, vinpocetine (2, 4 mg/kg) administration had certain beneficial effect on emotional memory. Our results suggest that vinpocetine could improve cognitive function in memory deficient mice and high clinic dosage might be better.

2016-12-01

Catatonia is a psychomotor syndrome that can be associated with both psychiatric diseases (mainly mood disorders, but also psychotic disorders) and medical conditions. Lorazepam (6-21 mg/day, occasionally up to 30 md/day) is the first choice treatment and electroconvulsive therapy (ECT) is the second line, regardless of the underlying clinical condition. There are some evidences also for effectiveness of other medications. Patients treated acutely usually show rapid and full therapeutic response but even longstanding catatonia can improve. However, some authors suggested that chronic catatonia in the context of schizophrenia is phenomenologically different and less responsive to lorazepam and ECT, especially if associated with echophenomena. We present here the case of a patient with longstanding catatonic schizophrenia treated with antipsychotics who significantly improved after ECT. Improvement regarded mainly catatonia, but also negative symptoms, cognition and psychosocial functioning. A slight amelioration in prefrontal metabolism (Brain[F]FDG PET) one month following the ECT course was also noted.

Although the short-term effects of urotherapy as a treatment strategy for lower urinary tract (LUT) conditions have been well documented, the long-term effects remain largely unknown. A better insight into the long-term effects of urotherapy could improve the clinical guidelines for children with incontinence. This study aimed to investigate the long-term effects (i.e., from 6 months to 2 years) from a clinical voiding reeducation program among children with LUT conditions. This study was a prospective continuation of the follow-up study of Hoebeke et al. (2011). Thirty-eight children (mean age 9 years) with LUT conditions completed an extensive clinical voiding reeducation program (VS). Data on medication, voiding, drinking, pelvic floor tone, uroflowmetry, and incontinence were recorded 2 years after the VS. These data were compared with the outcomes at 6 months follow-up and at intake before voiding school. Six months after voiding school, 22 children continued having daytime incontinence (ID) and/or enuresis (EN). Six of them became dry at 2 years. Conversely, 16 children were dry at 6 months, of which eight relapsed at 2 years. Whereas all parameters significantly improved 6 months after VS, further improvements from 6 months to 2 years could only be noticed for the proportion of children suffering from overactive bladder (92% at intake, 55% at 6-month follow-up and 18% at 2-year follow-up) (Figure). Fluid intake and pelvic floor tone improved after 6 months, but showed a significant relapse after 2 years (P = 0.013, P = 0.031, respectively). Hoebeke et al. (2011) concluded that results continued to improve after VS. No further improvements could be noticed 2 years after VS, although individual shifts were present. The results of the present study underline the value of long-term follow-up to detect those needing ongoing treatment to prevent relapse. Fluid intake and pelvic floor tone deteriorated from 6 months to 2 years. It could be hypothesized that inadequate fluid intake, possibly leading to decreased voided volumes, may be seen as an indicator for upcoming incontinence relapse. It could be stated that adequate fluid intake and pelvic floor tone may play a role in remaining continent for the long term. Study limitations should be considered. The study population was heterogeneous and rather small. Together with other missing values, this could have influenced the results. Close individual, long-term follow-up after clinical voiding reeducation in children is recommended in order to timely detect and prevent potential relapse.

CADU/CIS (Clinical and Administrative Decision-support Utility and Clinical Information System) is a clinical decision-support workstation that allows large volumes of clinical information systems data to be analyzed in a timely and user-friendly fashion. CARE PROCESS MEASUREMENT: For any given disease, subgroups of patients are identified, and automated, customized "clinical pathways" are generated. For each subgroup, the best practice norms for use of test and therapies are identified. Practice style variations are then compared to outcomes to focus inquiry on decisions that significantly affect outcomes. INTESTINAL OBSTRUCTION: Graduate Health Systems, a multisite integrated provider in the Philadelphia area, has used CADU/CIS to improve quality problems, reduce treatment-intensity variations, and improve clinical participation in care process evaluation and decision making. A task force selected intestinal obstruction without hernia as its first study because of the related high-volume and high-morbidity complications. Use of a ten-step method for clinical performance improvement showed that the intravenous administration of unnecessary fluids to 104 patients with intestinal obstruction induced congestive heart failure (CHF) in 5 patients. Task force members and other practicing physicians are now developing guidelines and other interventions aimed at fluid use. Indeed, the task force used CADU/CIS to identify an additional 250 patients in one year whose conditions were complicated by CHF. A clinical decision support tool can be instrumental in detecting problems with important clinical and economic implications, identifying their important underlying causes, tracking the associated tests and therapies, and monitoring interventions.

Objective Despite the success of empirically supported treatments for posttraumatic stress disorder (PTSD), sleep impairment frequently remains refractory following treatment for PTSD. This single-site, randomized controlled trial examined the effectiveness of sleep-directed hypnosis as a complement to an empirically supported psychotherapy for PTSD (cognitive processing therapy; CPT). Method Participants completed either 3 weeks of hypnosis (n = 52) or a symptom monitoring control condition (n = 56) before beginning standard CPT. Multilevel modeling was used to investigate differential patterns of change to determine whether hypnosis resulted in improvements in sleep, PTSD, and depression. An intervening variable approach was then used to determine whether improvements in sleep achieved during hypnosis augmented change in PTSD and depression during CPT. Results After the initial phase of treatment (hypnosis or symptom monitoring), the hypnosis condition showed significantly greater improvement than the control condition in sleep and depression, but not PTSD. After CPT, both conditions demonstrated significant improvement in sleep and PTSD; however, the hypnosis condition demonstrated greater improvement in depressive symptoms. As sleep improved, there were corresponding improvements in PTSD and depression, with a stronger relationship between sleep and PTSD. Conclusion Hypnosis was effective in improving sleep impairment, but those improvements did not augment gains in PTSD recovery during the trauma-focused intervention. Public Health Significance: This study suggests that hypnosis may be a viable treatment option in a stepped-care approach for treating sleep impairment in individuals suffering from PTSD.

Human papillomavirus (HPV) vaccination rates lag behind vaccination rates for other adolescent vaccines; a bundled intervention may improve HPV vaccination rates. Our objective is to evaluate the impact of quality improvement (QI) training plus a bundled practice-based intervention (provider prompts plus communication skills training plus performance feedback) on improving HPV vaccinations in pediatric resident continuity clinics. Staff and providers in 8 resident clinics participated in a 12-month QI study. The intervention included training to strengthen provider communication about the HPV vaccine. Clinics also implemented provider prompts, received monthly performance feedback, and participated in learning collaborative calls. The primary outcome measure was eligible visits with vaccination divided by vaccine-eligible visits (captured HPV vaccination opportunities). Practices performed chart audits that were fed into monthly performance feedback on captured HPV vaccination opportunities. We used conditional logistic regression (conditioning on practice) to assess captured vaccination opportunities, with the time period of the study (before and after the QI intervention) as the independent variable. Overall, captured opportunities for HPV vaccination increased by 16.4 percentage points, from 46.9% to 63.3%. Special cause was demonstrated by centerline shift, with 8 consecutive points above the preintervention mean. On adjusted analyses, patients were more likely to receive a vaccine during, versus before, the intervention (odds ratio: 1.87; 95% confidence interval: 1.54-2.28). Captured HPV vaccination rates improved at both well-child and other visits (by 11.7 and 13.0 percentage points, respectively). A bundled intervention of provider prompts and training in communication skills plus performance feedback increased captured opportunities for HPV vaccination.

Juvenile fibromyalgia (JFM) is a chronic musculoskeletal pain condition that is associated with reduced physical function. Recent research has demonstrated that cognitive-behavioral therapy (CBT) is effective in improving daily functioning among adolescents with JFM. However, it is not known whether these improvements were accompanied by increased physical activity levels. Our objective was to analyze secondary data from a randomized clinical trial of CBT to examine whether CBT was associated with improvement in objectively measured physical activity and whether actigraphy indices corresponded with self-reported functioning among adolescents with JFM. Participants were 114 adolescents (ages 11-18 years) recruited from pediatric rheumatology clinics that met criteria for JFM and were enrolled in a clinical trial. Subjects were randomly (1:1) assigned to receive either CBT or fibromyalgia education (FE). Participants wore a hip-mounted accelerometer for 1 week as part of their baseline and posttreatment assessments. The final sample included 68 subjects (94% female, mean age 15.2 years) for whom complete actigraphy data were obtained. Actigraphy measures were not found to correspond with self-reported improvements in functioning. While self-reported functioning improved in the CBT condition compared to FE, no significant changes were seen in either group for activity counts, sedentary, moderate, or vigorous activity. The CBT group had significantly lower peak and light activity at posttreatment. Actigraphy monitoring provides a unique source of information about patient outcomes. CBT intervention was not associated with increased physical activity in adolescents with JFM, indicating that combining CBT with interventions to increase physical activity may enhance treatment effects.

Idiopathic normal pressure hydrocephalus (INPH) diagnosis is challenging as it can be mimicked by other neurological conditions, such as neurodegenerative dementia and motor syndromes. Additionally, outcomes after lumbar puncture (LP) tap test and shunt treatment may vary due to the lack of a common protocol in INPH assessment. The present study aimed to assess whether a post-LP test amelioration of frontal cognitive dysfunctions, characterizing this syndrome, can differentiate INPH from similar neurological conditions and whether this improvement can predict INPH post-shunt outcomes. Seventy-one consecutive patients referred for INPH suspicion and LP testing, were enrolled. According to the consensus guidelines criteria, 29 patients were diagnosed as INPH and 42 were assigned an alternative diagnosis (INPH-like group) after reviewing clinical, neuropsychological and imaging data, and before LP results. A comprehensive neuropsychological assessment for frontal executive, upper extremity fine motor functions, aphasias, apraxias, agnosias and gait evaluation were administered at baseline. Executive, fine motor functions and gait were re-examined post-LP test in all patients and post-shunt placement in INPH patients. Of the INPH patients, 86.2% showed cognitive amelioration in the post-LP test; in addition, all but one (97%) presented with neurocognitive and gait improvement post-shunt. Verbal phonological fluency and finger tapping task post-LP improvement predicted positive clinical outcome post-shunt. None of the INPH-like group presented with neurocognitive improvement post-LP. Post-LP amelioration of verbal fluency and finger tapping deficits can differentiate INPH from similar disorders and predict positive post-shunt clinical outcome in INPH. This becomes of great importance when gait assessment is difficult to perform in clinical practice.

Clinical decision making is a complex process and might be influenced by a wide range of clinical and non-clinical factors. Little is known about this process in dermatology. The aim of this study was to explore the different types of management decisions made in dermatology and to identify factors influencing those decisions from observation of consultations and interviews with the patients. 61 patient consultations were observed by a physician with experience in dermatology. The patients were interviewed immediately after each consultation. Consultations and interviews were audio recorded, transcribed and their content analysed using thematic content analysis. The most common management decisions made during the consultations included: follow-up, carrying out laboratory investigation, starting new topical treatment, renewal of systemic treatment, renewal of topical treatment, discharging patients and starting new systemic treatment. Common influences on those decisions included: clinical factors such as ineffectiveness of previous therapy, adherence to prescribing guidelines, side-effects of medications, previous experience with the treatment, deterioration or improvement in the skin condition, and chronicity of skin condition. Non-clinical factors included: patient's quality of life, patient's friends or relatives, patient's time commitment, travel or transportation difficulties, treatment-related costs, availability of consultant, and availability of treatment. The study has shown that patients are aware that management decisions in dermatology are influenced by a wide range of clinical and non-clinical factors. Education programmes should be developed to improve the quality of decision making. Copyright © 2010 S. Karger AG, Basel.

Postural instability appears to be a dopamine resistance motor deficit in persons with Parkinson disease (PD); however, little is known about the effects of dopamine replacement on the relative biomechanical contributions of individual lower extremity joints during postural control tasks. To gain insight, we examined persons with PD using both clinical and laboratory measures. For a clinical measure of motor severity we utilized the Unified Parkinson Disease Rating Scale motor subsection during both OFF and ON medication conditions. For the laboratory measure we utilized data gathered during a rapid lower extremity force production task. Kinematic and kinetic variables at the hip, knee, and ankle were gathered during a counter movement jump during both OFF and ON medication conditions. Sixteen persons with PD with a median Hoehn and Yahr severity of 2.5 completed the study. Medication resulted in significant improvements of angular displacement for the hip, knee, and ankle. Furthermore, significant improvements were revealed only at the hip for peak net moments and average angular velocity compared to the OFF medication condition. These results suggest that dopamine replacement medication result in decreased clinical motor disease severity and have a greater influence on kinetics and kinematics proximally. This proximally focused improvement may be due to active recruitment of muscle force and reductions in passive restraint during lower extremity rapid force production. Copyright © 2013 Elsevier B.V.

Systematic review. Joint mobilizations are used as an intervention for improving range of motion, decreasing pain and ultimately improving function in patients with a wide variety of upper extremity diagnoses. However, there are only a limited number of studies describing this treatment for conditions affecting the elbow, wrist, and hand. Furthermore, it is unclear as to the most effective joint mobilization technique utilized and the most beneficial functional outcomes gained. Examine the current evidence describing joint mobilizations for treatment of conditions of the elbow, wrist and hand, and offer informative practical clinical guidance. Twenty-two studies dated between 1980 and 2011 were included in the systematic review for analysis. The current evidence provides moderate support for the inclusion of joint mobilizations in the treatment of lateral epicondylalgia (LE). In particular, mobilization with movement as described by Mulligan is supported with evidence from nine randomized clinical trials as an effective technique for the treatment of pain. Other described techniques include those known as Kaltenborn, Cyriax physical therapy, and Maitland, but the evidence for these techniques is limited. There is also limited evidence for the joint mobilizations in the treatment of wrist and hand conditions. The current literature offers limited support for joint mobilizations of the wrist and hand, and moderate support for joint mobilizations of the elbow for LE. There is moderate support for mobilization with movement. . Copyright © 2013 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

Autoimmune encephalitis and its relation to infection.

PubMed

Venkatesan, Arun; Benavides, David R

2015-03-01

Encephalitis, an inflammatory condition of the brain that results in substantial morbidity and mortality, has numerous causes. Over the past decade, it has become increasingly recognized that autoimmune conditions contribute significantly to the spectrum of encephalitis causes. Clinical suspicion and early diagnosis of autoimmune etiologies are of particular importance due to the need for early institution of immune suppressive therapies to improve outcome. Emerging clinical observations suggest that the most commonly recognized cause of antibody-mediated autoimmune encephalitis, anti-N-methyl-D-aspartate (NMDA) receptor encephalitis, may in some cases be triggered by herpes virus infection. Other conditions such as Rasmussen's encephalitis (RE) and febrile infection-related epilepsy syndrome (FIRES) have also been posited to be autoimmune conditions triggered by infectious agents. This review focuses on emerging concepts in central nervous system autoimmunity and addresses clinical and mechanistic findings linking autoimmune encephalitis and infections. Particular consideration will be given to anti-NMDA receptor encephalitis and its relation to herpes simplex encephalitis.

Conditionally replicative adenovirus for gastrointestinal cancers.

Yamamoto, Masato

2004-08-01

The clinical outcome of advanced gastrointestinal (GI) cancers (especially pancreatic and oesophageal cancers) is dismal, despite the advance of conventional therapeutic strategies. Cancer gene therapy is a category of new therapeutics, among which conditionally replicative adenovirus (CRAd) is one promising strategy to overcome existing obstacles of cancer gene therapy. Various CRAds have been developed for GI cancer treatment by taking advantage of the replication biology of adenovirus. Some CRAds have already been tested in clinical trials, but have fallen short of initial expectations. Concerns for clinical applicability include therapeutic potency, replication selectivity and interval end points in clinical trials. In addition, improvement of experimental animal models is needed for a deeper understanding of CRAd biology. Despite these obstacles, CRAds continue to be an exciting area of investigation with great potential for clinical utility. Further virological and oncological research will eventually lead to full realisation of the therapeutic potential of CRAds in the field of GI cancers.

Imaging of neurodegenerative cognitive and behavioral disorders: practical considerations for dementia clinical practice.

PubMed

Atri, Alireza

2016-01-01

This chapter reviews clinical applications and imaging findings useful in medical practice relating to neurodegenerative cognitive/dementing disorders. The preponderance of evidence and consensus guidelines support an essential role of multitiered neuroimaging in the evaluation and management of neurodegenerative cognitive/dementia syndrome that range in severity from mild impairments to frank dementia. Additionally, imaging features are incorporated in updated clinical and research diagnostic criteria for most dementias, including Alzheimer's disease (AD), Dementia with Lewy bodies (DLB), Frontotemporal Lobar Degenerations/Frontotemporal Dementia (FTD), and Vascular Cognitive Impairment (VCI). Best clinical practices dictate that structural imaging, preferably with magnetic resonance imaging (MRI) when possible and computed tomography when not, be obtained as a first-tier approach during the course of a thorough clinical evaluation to improve diagnostic confidence and assess for nonneurodegenerative treatable conditions that may cause or substantially contribute to cognitive/behavioral symptoms or which may dictate a substantial change in management. These conditions include less common structural (e.g., mass lesions such as tumors and hematomas; normal-pressure hydrocephalus), inflammatory, autoimmune and infectious conditions, and more common comorbid contributing conditions (e.g., vascular cerebral injury causing leukoaraiosis, infarcts, or microhemorrhages) that can produce a mixed dementia syndrome. When, after appropriate clinical, cognitive/neuropsychologic, and structural neuroimaging assessment, a dementia specialist remains in doubt regarding etiology and appropriate management, second-tier imaging with molecular methods, preferably with fluorodexoyglucose positron emission tomography (PET) (or single-photon emission computed tomography if PET is unavailable) can provide more diagnostic specificity (e.g., help differentiate between atypical AD and FTD as the etiology for a frontal/dysexecutive syndrome). The potential clinical utility of other promising methods, whether already approved for use (e.g., amyloid PET) or as yet only used in research (e.g., tau PET, functional MRI, diffusor tensor imaging), remains to be proven for widespread use in community practice. However, these constitute unreimbursed third-tier options that merit further study for clinical and cost-effective utility. In the future, combination use of imaging methods will likely improve diagnostic accuracy. © 2016 Elsevier B.V. All rights reserved.

The aim of the present study was to investigate the prognostic value of geriatric conditions beyond age after acute coronary syndrome. This was a prospective cohort design including 342 patients (from October 1, 2010, to February 1, 2012) hospitalized for acute coronary syndrome, older than 65 years, in whom 5 geriatric conditions were evaluated at discharge: frailty (Fried and Green scales), comorbidity (Charlson and simple comorbidity indexes), cognitive impairment (Pfeiffer test), physical disability (Barthel index), and instrumental disability (Lawton-Brody scale). The primary end point was all-cause mortality. The median follow-up for the entire population was 4.7 years (range, 3-2178 days). A total of 156 patients (46%) died. Among the geriatric conditions, frailty (Green score, per point; hazard ratio, 1.11; 95% CI, 1.02-1.20; P=.01) and comorbidity (Charlson index, per point; hazard ratio, 1.18; 95% CI, 1.0-1.40; P=.05) were the independent predictors. The introduction of age in a basic model using well-established prognostic clinical variables resulted in an increase in discrimination accuracy (C-statistic=.716-.744; P=.05), though the addition of frailty and comorbidity provided a nonsignificant further increase (C-statistic=.759; P=.36). Likewise, the addition of age to the clinical model led to a significant risk reclassification (continuous net reclassification improvement, 0.46; 95% CI, 0.21-0.67; and integrated discrimination improvement, 0.04; 95% CI, 0.01-0.09). However, the addition of frailty and comorbidity provided a further significant risk reclassification in comparison to the clinical model with age (continuous net reclassification improvement, 0.40; 95% CI, 0.16-0.65; and integrated discrimination improvement, 0.04; 95% CI, 0.01-0.10). In conclusion, frailty and comorbidity are mortality predictors that significantly reclassify risk beyond age after acute coronary syndrome.

Mobile applications for improving diagnostic decision making often lack clinical evaluation. We evaluated if a mobile application improves generalist physicians' appropriate laboratory test ordering and diagnosis decisions and assessed if physicians perceive it as useful for learning. In an experimental, vignette study, physicians diagnosed 8 patient vignettes with normal prothrombin times (PT) and abnormal partial thromboplastin times (PTT). Physicians made test ordering and diagnosis decisions for 4 vignettes using each resource: a mobile app, PTT Advisor, developed by the Centers for Disease Control and Prevention (CDC)'s Clinical Laboratory Integration into Healthcare Collaborative (CLIHC); and usual clinical decision support. Then, physicians answered questions regarding their perceptions of the app's usefulness for diagnostic decision making and learning using a modified Kirkpatrick Training Evaluation Framework. Data from 368 vignettes solved by 46 physicians at 7 US health care institutions show advantages for using PTT Advisor over usual clinical decision support on test ordering and diagnostic decision accuracy (82.6 vs 70.2% correct; P < .001), confidence in decisions (7.5 vs 6.3 out of 10; P < .001), and vignette completion time (3:02 vs 3:53 min.; P = .06). Physicians reported positive perceptions of the app's potential for improved clinical decision making, and recommended it be used to address broader diagnostic challenges. A mobile app, PTT Advisor, may contribute to better test ordering and diagnosis, serve as a learning tool for diagnostic evaluation of certain clinical disorders, and improve patient outcomes. Similar methods could be useful for evaluating apps aimed at improving testing and diagnosis for other conditions.

Measuring performance improvement: total organizational commitment or clinical specialization.

Caron, Aleece; Jones, Paul; Neuhauser, Duncan; Aron, David C

Resources for hospitals are limited when they are faced with multiple publicly reported performance measures as tools to assess quality. The leadership in these organizations may choose to focus on 1 or 2 of these outcomes. An alternative approach is that the leadership may commit resources or create conditions that result in improved quality over a broad range of measures. We used aggregated data on mortality, length of stay, and obstetrical outcomes from Greater Cleveland Health Quality Choice data to test these theories. We used Pearson correlation analysis to determine of outcomes were correlated with one another. We used repeated-measures ANOVA to determine if an association existed between outcome and time and outcome and hospital. All of the outcomes across all hospitals demonstrate a trend of overall improvement. Both the Pearson and ANOVA result support the hypothesis for the organization-wide approach to quality improvement. Hospital that make improvements in one clinical area trend to make improvements in others. Hospitals that produce improvements in limited clinical or administrative areas may not have completely adopted CQI into their culture or may not have yet realized the benefits of their organizational commitments, but use some of the concepts to improve quality outcomes.

Attendance at a specialist multidisciplinary motor neurone disease (MND) clinic is associated with improved survival and may also improve quality of life and reduce hospital admissions. However, patients struggle to travel to clinic and may experience difficulties between clinic visits that may not be addressed in a timely manner. We wanted to explore how we could improve access to specialist MND care. We adopted an iterative, user-centered co-design approach, collaborating with those with experience of providing and receiving MND care including patients, carers, clinicians, and technology developers. We explored the unmet needs of those living with MND, how they might be met through service redesign and through the use of digital technologies. We developed a new digital solution and performed initial testing with potential users including clinicians, patients, and carers. We used these findings to develop a telehealth system (TiM) using an Android app into which patients and carers answer a series of questions about their condition on a weekly basis. The questions aim to capture all the physical, emotional, and social difficulties associated with MND. This information is immediately uploaded to the internet for review by the MND team. The data undergoes analysis in order to alert clinicians to any changes in a patient or carer's condition. We describe the benefits of developing a novel digitally enabled service underpinned by participatory design. Future trials must evaluate the feasibility and acceptability of the TiM system within a clinical environment.

2016-01-01

Objectives We evaluated the effects of three doses of a behavioral intervention for obesity (High dose = 24 sessions, Moderate = 16 sessions, Low = 8 sessions) compared with a nutrition education control group (Control) on binge eating. We also examined whether participants with clinically significant improvements in binge eating had better treatment adherence and weight-loss outcomes than those who did not experience clinically significant improvements in binge eating. Finally, we examined the relation of pretreatment binge eating severity to changes at six months. Methods Participants included 572 adults (female = 78.7%; baseline mean ±SD: age = 52.7 ±11.2 years, BMI = 36.4 ±3.9 kg/m2) who provided binge eating data at baseline. We evaluated binge eating severity (assessed via the Binge Eating Scale) and weight status at baseline and six months, as well as treatment adherence over six months. Results At six months, participants in the Moderate and High treatment conditions reported greater reductions in binge eating severity than participants in the Low and Control conditions, ps < .02. Participants who demonstrated improvements in binge eating severity reported greater dietary self-monitoring adherence and attained larger weight losses than those who did not experience clinically significant reductions, ps < .001. Pretreatment binge eating severity predicted less improvement in binge eating severity over six months and fewer days with dietary self-monitoring records completed, ps ≤ .002. Conclusion A moderate or high dose of behavioral weight-loss treatment may be required to produce clinically significant reductions in binge eating severity in adults with obesity. PMID:27086049

We describe a case of E. fergusonii bacteremia in a diabetic patient with pancreatic cancer. The isolate was confirmed by three commercial identification systems and 16S rRNA gene sequence analysis. The patient's clinical condition gradually improved, and repeated blood cultures were negative after antibiotic treatment with an in vitro active agent (ceftriaxone).

Background: Non-traumatic spinal cord dysfunction (SCDys) is caused by a large range of heterogeneous etiologies. Although most aspects of rehabilitation for traumatic spinal cord injury and SCDys are the same, people with SCDys have some unique rehabilitation issues. Purpose: This article presents an overview of important clinical rehabilitation principles unique to SCDys. Methods: Electronic literature search conducted (January 2017) using MEDLINE and Embase (1990-2016) databases for publications regarding SCDys. The focus of the literature search was on identifying publications that present suggestions regarding the clinical rehabilitation of SCDys. Results: The electronic search of MEDLINE and Embase identified no relevant publications, and the publications included were from the authors' libraries. A number of important clinical rehabilitation principles unique to people with SCDys were identified, including classification issues, general rehabilitation issues, etiology-specific issues, and a role for the rehabilitation physician as a diagnostic clinician. The classification issues were regarding the etiology of SCDys and the International Standards for Neurological Classification of Spinal Cord Injury. The general rehabilitation issues were predicting survival, improvement, and rehabilitation outcomes; admission to spinal rehabilitation units, including selection decision issues; participation in rehabilitation; and secondary health conditions. The etiology-specific issues were for SCDys due to spinal cord degeneration, tumors, and infections. Conclusions: Although there are special considerations regarding the rehabilitation of people with SCDys, such as the potential for progression of the underlying condition, functional improvement is typically significant with adequate planning of rehabilitation programs and special attention regarding the clinical condition of patients with SCDys.

Turner syndrome, a congenital condition that affects ∼1/2,500 births, results from absence or structural alteration of the second sex chromosome. There has been substantial effort by numerous clinical and genetic research groups to delineate the clinical, pathophysiological, cytogenetic, and molecular features of this multisystem condition. Questions about the molecular-genetic and biological basis of many of the clinical features remain unanswered, and health care providers and families seek improved care for affected individuals. The inaugural “Turner Resource Network (TRN) Symposium” brought together individuals with Turner syndrome and their families, advocacy group leaders, clinicians, basic scientists, physician-scientists, trainees and other stakeholders with interest in the well-being of individuals and families living with the condition. The goal of this symposium was to establish a structure for a TRN that will be a patient-powered organization involving those living with Turner syndrome, their families, clinicians, and scientists. The TRN will identify basic and clinical questions that might be answered with registries, clinical trials, or through bench research to promote and advocate for best practices and improved care for individuals with Turner syndrome. The symposium concluded with the consensus that two rationales justify the creation of a TRN: inadequate attention has been paid to the health and psychosocial issues facing girls and women who live with Turner syndrome;investigations into the susceptibility to common disorders such as cardiovascular or autoimmune diseases caused by sex chromosome deficiencies will increase understanding of disease susceptibilities in the general population.

[Overdenture supported by natural teeth: analysis of clinical advantages].

PubMed

Scotti, R; Melilli, D; Pizzo, G

2003-05-01

Hybrid prosthesis supported by natural teeth (overdenture) is widely used in clinical practice and should be executed whenever the clinical conditions suggest it. Through a critical review of the literature, the anatomical, functional, psychological and clinical advantages are emphasized. Among the first ones, the prophylaxis of residual anatomical components, due to the limitation of bone resorption, and the preservation of sensorial proprioception are relevant. Important advantages are also represented by a better crown-root ratio of residual teeth supporting overdenture, with the consequent improvement of the longitudinal prognosis of such teeth. The greater retention and stability of overdenture in comparison with complete denture greatly improve the masticatory efficacy. The psychological advantages resulting from the dental anchorage, which allows the patient to be more confident in social life, are also relevant. Finally, when the dental support is lost, converting overdenture into complete denture is simple and quick, and makes easier the longitudinal clinical maintenance of the denture.

Introduction Internal medicine (IM) interns start continuity clinic with variable ambulatory training. Multiple other specialties have utilized a boot camp style curriculum to improve surgical and procedural skills, but boot camps have not been used to improve interns’ ambulatory knowledge and confidence. The authors implemented and assessed the impact of an intern ambulatory boot camp pilot on primary care knowledge, confidence, and curricular satisfaction. Methods During July 2014, IM interns attended ambulatory boot camp. It included clinically focused case-based didactic sessions on common ambulatory topics as well as orientation to the clinic and electronic medical records. Interns anonymously completed a 15-question pre-test on topics covered in the boot camp as well as an identical post-test after the boot camp. The interns were surveyed regarding their confidence and satisfaction. Results Thirty-eight interns participated in the boot camp. Prior to the boot camp, few interns reported confidence managing common outpatient conditions. The average pre-test knowledge score was 46.3%. The average post-test knowledge score significantly improved to 76.1% (p<0.001). All interns reported that the boot camp was good preparation for clinics and 97% felt that the boot camp boosted their confidence. Conclusions The ambulatory boot camp pilot improved primary care knowledge, and interns thought it was good preparation for clinic. The ambulatory boot camp was well received and may be an effective way to improve the preparation of interns for primary care clinic. Further assessment of clinical performance and expansion to other programs and specialties should be considered. PMID:26609962

Because of the anatomical location, patients with head and neck cancer (HNC) frequently experience dysphagia and malnutrition at the time of diagnosis and these conditions are often exacerbated after chemoradiotherapy. There is an emerging medical need to establish a consensus on nutritional intervention for these patients. A panel of 30 senior physicians and experts from multidisciplinary teams drafted clinical recommendations to improve the management of nutritional interventions in Taiwan and to provide updated treatment strategy recommendations in hope of improving the nutritional status of patients with HNC. This clinical review describes the resulting consensus document, including the impact of malnutrition on clinical outcomes, the role of prophylactic tube feeding, the choice of tube feeding, and the benefit of oral nutritional supplements in patients with HNC undergoing chemoradiotherapy. The outcomes of this review will support clinicians in their efforts to improve the nutritional status of patients with HNC. Copyright © 2018 Elsevier Ltd. All rights reserved.

Managing patients with neurologic disorders who participate in sports activities.

2014-12-01

Patients with neurologic conditions have been discouraged from participating in organized sports because of theoretical detrimental effects of these activities to their underlying conditions. The purpose of this article is to review known risks associated with three specific clinical conditions most commonly encountered in a sports neurology clinic (epilepsy, migraines, and multiple sclerosis and to add to the neurologist's toolkit suggested interventions regarding management of athletes with these disorders. Increased participation in sports and athletics has positive benefits for patients with neurologic conditions and can be safely integrated into the lives of these patients with proper supervision from their treating neurologists. Patients with neurologic conditions can and should be encouraged to participate in organized sports as a method of maintaining their overall fitness, improving their overall level of function, and reaping the physical and psychological benefits that athletic competition has to offer.

Effect of improving the realism of simulated clinical judgement tasks on nurses' overconfidence and underconfidence: evidence from a comparative confidence calibration analysis.

Apparent overconfidence and underconfidence in clinicians making clinical judgements could be a feature of evaluative research designs that fail to accurately represent clinical environments. To test the effect of improved realism of clinical judgement tasks on confidence calibration performance of nurses and student nurses. A comparative confidence calibration analysis. The study was conducted in a large university of Northern England. Ninety-seven participants rated their confidence - using a scale that ranged from 0 (no confidence) to 100 (totally confident) on dichotomous clinical judgements of critical event risk. The judgements were in response to 25 paper-based and 25 higher fidelity scenarios using a computerised patient simulator and clinical equipment. Scenarios, and judgement criteria of 'correctness', were generated from real patient cases. Using a series of calibration measures (calibration, resolution and over/underconfidence), participants' confidence was calibrated against the proportion of correct judgements. The calibration measures generated by the paper-based and high fidelity clinical simulation conditions were compared. Participants made significantly less accurate clinical judgements of risk in the high fidelity clinical simulations compared to the paper simulations (P=0.0002). They were significantly less confident in high fidelity clinical simulations than paper simulations (P=0.03). However, there was no significant difference of over/underconfidence for participants between the two simulated settings (P=0.06). Participants were no better calibrated in the high fidelity clinical simulations than paper simulations, P=0.85. Likewise, participants had no better ability of discriminating correct judgements from incorrect judgements as measured by the resolution statistic in high fidelity clinical simulations than paper simulations, P=0.76. Improving the realism of simulated judgement tasks led to reduced confidence and judgement accuracy in participants but did not alter confidence calibration. These findings suggest that judgemental miscalibration of confidence in nurses may be a systematic cognitive bias and that simply making scenarios more realistic may not be a sufficient condition for correction.

Health coaching by medical assistants could be a financially viable model for providing self-management support in primary care if its effectiveness were demonstrated. We investigated whether in-clinic health coaching by medical assistants improves control of cardiovascular and metabolic risk factors when compared with usual care. We conducted a 12-month randomized controlled trial of 441 patients at 2 safety net primary care clinics in San Francisco, California. The primary outcome was a composite measure of being at or below goal at 12 months for at least 1 of 3 uncontrolled conditions at baseline as defined by hemoglobin A1c, systolic blood pressure, and low-density lipoprotein (LDL) cholesterol. Secondary outcomes were meeting all 3 goals and meeting individual goals. Data were analyzed using χ(2) tests and linear regression models. Participants in the coaching arm were more likely to achieve both the primary composite measure of 1 of the clinical goals (46.4% vs 34.3%, P = .02) and the secondary composite measure of reaching all clinical goals (34.0% vs 24.7%, P = .05). Almost twice as many coached patients achieved the hemoglobin A1c goal (48.6% vs 27.6%, P = .01). At the larger study site, coached patients were more likely to achieve the LDL cholesterol goal (41.8% vs 25.4%, P = .04). The proportion of patients meeting the systolic blood pressure goal did not differ significantly. Medical assistants serving as in-clinic health coaches improved control of hemoglobin A1c and LDL levels, but not blood pressure, compared with usual care. Our results highlight the need to understand the relationship between patients' clinical conditions, interventions, and the contextual features of implementation. © 2015 Annals of Family Medicine, Inc.

Advanced Multi-Axis Spine Testing: Clinical Relevance and Research Recommendations

Holsgrove, Timothy P.; Nayak, Nikhil R.; Welch, William C.

2015-01-01

Back pain and spinal degeneration affect a large proportion of the general population. The economic burden of spinal degeneration is significant, and the treatment of spinal degeneration represents a large proportion of healthcare costs. However, spinal surgery does not always provide improved clinical outcomes compared to non-surgical alternatives, and modern interventions, such as total disc replacement, may not offer clinically relevant improvements over more established procedures. Although psychological and socioeconomic factors play an important role in the development and response to back pain, the variation in clinical success is also related to the complexity of the spine, and the multi-faceted manner by which spinal degeneration often occurs. The successful surgical treatment of degenerative spinal conditions requires collaboration between surgeons, engineers, and scientists in order to provide a multi-disciplinary approach to managing the complete condition. In this review, we provide relevant background from both the clinical and the basic research perspectives, which is synthesized into several examples and recommendations for consideration in increasing translational research between communities with the goal of providing improved knowledge and care. Current clinical imaging, and multi-axis testing machines, offer great promise for future research by combining invivo kinematics and loading with in-vitro testing in six degrees of freedom to offer more accurate predictions of the performance of new spinal instrumentation. Upon synthesis of the literature, it is recommended that in-vitro tests strive to recreate as many aspects of the in-vivo environment as possible, and that a physiological preload is a critical factor in assessing spinal biomechanics in the laboratory. A greater link between surgical procedures, and the outcomes in all three anatomical planes should be considered in both the in-vivo and in-vitro settings, to provide data relevant to quality of motion, and stability.

Reexpression of Prior Stroke Symptoms in Adults: When is a Mimic a Mimic?

PubMed

Siegler, James E; George, Alexander J; Martin-Schild, Sheryl

2017-09-01

A "stroke mimic" refers to any clinical condition that causes neurological symptoms clinically indistinguishable from a cerebral lesion that affects a vascular distribution, but is not caused by ischemia. One subtype of stroke mimic, termed stroke reexpression, is a form of mimicry in which previously recovered or improved stroke symptoms recur in the setting of a neurological disturbance (seizure, hypoperfusion state) or a systemic disturbance (toxic, metabolic, infectious). Many reports of stroke reexpression exist in the literature and are well known to clinicians, but there has been no consensus regarding terminology that has been published to date. The purpose of this review is to summarize several examples of stroke reexpression and propose simple, useful criteria for this clinical condition.

Young people living with long term conditions are vulnerable to health service disengagement. This endangers their long term health. Studies report requests for digital forms of communication - email, text, social media - with their health care team. Digital clinical communication is troublesome for the UK NHS. In this article we aim to present the research protocol for evaluating the impacts and outcomes of digital clinical communications for young people living with long term conditions and provide critical analysis of their use, monitoring and evaluation by NHS providers (LYNC study: Long term conditions, Young people, Networked Communications). The research involves: (a) patient and public involvement activities with 16-24 year olds with and without long term health conditions; (b) six literature reviews; (c) case studies - the main empirical part of the study - and (d) synthesis and a consensus meeting. Case studies use a mixed methods design. Interviews and non-participant observation of practitioners and patients communicating in up to 20 specialist clinical settings will be combined with data, aggregated at the case level (non-identifiable patient data) on a range of clinical outcomes meaningful within the case and across cases. We will describe the use of digital clinical communication from the perspective of patients, clinical staff, support staff and managers, interviewing up to 15 young people and 15 staff per case study. Outcome data includes emergency admissions, A&E attendance and DNA (did not attend) rates. Case studies will be analysed to understand impacts of digital clinical communication on patient health outcomes, health care costs and consumption, ethics and patient safety.

Colloids and the Microcirculation.

Colloid solutions have been advocated for use in treating hypovolemia due to their expected effect on improving intravascular retention compared with crystalloid solutions. Because the ultimate desired effect of fluid resuscitation is the improvement of microcirculatory perfusion and tissue oxygenation, it is of interest to study the effects of colloids and crystalloids at the level of microcirculation under conditions of shock and fluid resuscitation, and to explore the potential benefits of using colloids in terms of recruiting the microcirculation under conditions of hypovolemia. This article reviews the physiochemical properties of the various types of colloid solutions (eg, gelatin, dextrans, hydroxyethyl starches, and albumin) and the effects that they have under various conditions of hypovolemia in experimental and clinical scenarios.

Background Youth with special health care needs often experience difficulty transitioning from pediatric to adult care. These difficulties may derive in part from lack of physician training in transition care and the challenges health care providers experience establishing interdisciplinary partnerships to support these patients. Objective This educational innovation sought to improve pediatrics and adult medicine residents' interdisciplinary communication and collaboration. Methods Residents from pediatrics, medicine-pediatrics, and internal medicine training programs participated in a transitions clinic for patients with chronic health conditions aged 16 to 26 years. Residents attended 1 to 4 half-day clinic sessions during 1-month ambulatory rotations. Pediatrics/adult medicine resident dyads collaboratively performed psychosocial and medical transition consultations that addressed health care navigation, self-care, and education and vocation topics. Two to 3 attending physicians supervised each clinic session (4 hours) while concurrently seeing patients. Residents completed a preclinic survey about baseline attitudes and experiences, and a postclinic survey about their transitions clinic experiences, changes in attitudes, and transition care preparedness. Results A total of 46 residents (100% of those eligible) participated in the clinic and completed the preclinic survey, and 25 (54%) completed the postclinic survey. A majority of respondents to the postclinic survey reported positive experiences. Residents in both pediatrics and internal medicine programs reported improved preparedness for providing transition care to patients with chronic health conditions and communicating effectively with colleagues in other disciplines. Conclusions A dyadic model of collaborative transition care training was positively received and yielded improvements in immediate self-assessed transition care preparedness. PMID:28439357

The mast cell lives a hidden life, but it is implicated in several physiological reactions. Its ability to react to different stimuli impacts a variety of conditions such as asthma, atopic dermatitis, urticaria and anaphylaxis. It is not until recent decades that the evolution of the cell has been described and its fascinating biology has only recently been depicted. We here give a review of systemic mastocytosis in regards to cell biology, diagnostic approaches and clinical practice. A search was made in PubMed in August 2011 entering the keywords: mastocytosis, (systemic, cutaneous, aggressive), mast cell leukaemia, mast cell sarcoma, chromosome, mutation, haematology and treatment. Mastocytosis is characterized by an abnormal proliferation of mast cells, which accumulate in one or several organ systems, primarily the skin and bone marrow. The disease is clinically heterogeneous and varies from a relatively benign condition with isolated cutaneous lesions to a very aggressive systemic condition with a grave prognosis. The condition affects men and women equally. Children are especially affected by the cutaneous form. In most children, the condition will improve or remit spontaneously before adulthood. Mastocytosis in adults, however, is more often systemic and tends to persist. Patients with mastocytosis represent a heterogeneous group in terms of clinical presentation, management and prognosis. Furthermore, a range of medical specialties serve as the primary entrance to health services, which can be a challenge in respect of achieving uniform management. In order to improve diagnostics and management of systemic mastocytosis, the European Competence Network on Mastocytosis has been established. Patients under suspicion of systemic mastocytosis should be conferred with or referred to a haematological and a dermatological/allergological department.

Emerging drugs for diabetic peripheral neuropathy and neuropathic pain.

Papanas, Nikolaos; Ziegler, Dan

2016-12-01

Diabetic sensorimotor polyneuropathy (DSPN) is a common complication of diabetes. Areas covered: In this review, the authors discuss the emerging drugs for DSPN, which aim either at improving alleviation of neuropathic pain or addressing the putative mechanisms underlying diabetic neuropathy. Expert Opinion: Current treatment does not address the sensory deficits and pathogenesis underlying DSPN, so there is an unmet need for treatment options targeting the natural history of the condition. Some of these pathogenetic therapies have demonstrated clinically relevant improvements in neuropathic endpoints in recent randomised controlled trials. Since any effective analgesic monotherapy is known to induce a clinically meaningful response in only some 50% of the patients, there remains a substantial unmet need in patients with neuropathic pain. Advanced knowledge in the neurobiology of neuropathic pain and improved phenotypic profiling have led to a burst of research into novel pharmaceutical approaches. An array of promising molecular entities have reached the clinical stage of development, which should improve our therapeutic armamentarium in the fight against DSPN and neuropathic pain in the foreseeable future.

Clinical verification in homeopathy and allergic conditions.

Van Wassenhoven, Michel

2013-01-01

The literature on clinical research in allergic conditions treated with homeopathy includes a meta-analysis of randomised controlled trials (RCT) for hay fever with positive conclusions and two positive RCTs in asthma. Cohort surveys using validated Quality of Life questionnaires have shown improvement in asthma in children, general allergic conditions and skin diseases. Economic surveys have shown positive results in eczema, allergy, seasonal allergic rhinitis, asthma, food allergy and chronic allergic rhinitis. This paper reports clinical verification of homeopathic symptoms in all patients and especially in various allergic conditions in my own primary care practice. For preventive treatments in hay fever patients, Arsenicum album was the most effective homeopathic medicine followed by Nux vomica, Pulsatilla pratensis, Gelsemium, Sarsaparilla, Silicea and Natrum muriaticum. For asthma patients, Arsenicum iodatum appeared most effective, followed by Lachesis, Calcarea arsenicosa, Carbo vegetabilis and Silicea. For eczema and urticaria, Mezereum was most effective, followed by Lycopodium, Sepia, Arsenicum iodatum, Calcarea carbonica and Psorinum. The choice of homeopathic medicine depends on the presence of other associated symptoms and 'constitutional' features. Repertories should be updated by including results of such clinical verifications of homeopathic prescribing symptoms. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd.

To improve the accuracy and precision of tracer kinetic model parameter estimates for use in dynamic contrast enhanced (DCE) MRI studies of solid tumors. Quantitative DCE-MRI requires an estimate of precontrast T1 , which is obtained prior to fitting a tracer kinetic model. As T1 mapping and tracer kinetic signal models are both a function of precontrast T1 it was hypothesized that its joint estimation would improve the accuracy and precision of both precontrast T1 and tracer kinetic model parameters. Accuracy and/or precision of two-compartment exchange model (2CXM) parameters were evaluated for standard and joint fitting methods in well-controlled synthetic data and for 36 bladder cancer patients. Methods were compared under a number of experimental conditions. In synthetic data, joint estimation led to statistically significant improvements in the accuracy of estimated parameters in 30 of 42 conditions (improvements between 1.8% and 49%). Reduced accuracy was observed in 7 of the remaining 12 conditions. Significant improvements in precision were observed in 35 of 42 conditions (between 4.7% and 50%). In clinical data, significant improvements in precision were observed in 18 of 21 conditions (between 4.6% and 38%). Accuracy and precision of DCE-MRI parameter estimates are improved when signal models are fit jointly rather than sequentially.

2012-01-01

In mobile health (M-health), Short Message Service (SMS) has shown to improve disease related self-management and health service outcomes, leading to enhanced patient care. However, the hard limit on character size for each message limits the full value of exploring SMS communication in health care practices. To overcome this problem and improve the efficiency of clinical workflow, we developed an innovative system, MedTxting (available at http://medtxting.askhermes.org), which is a learning-based but knowledge-rich system that compresses medical texts in a SMS style. Evaluations on clinical questions and discharge summary narratives show that MedTxting can effectively compress medical texts with reasonable readability and noticeable size reduction. Findings in this work reveal potentials of MedTxting to the clinical settings, allowing for real-time and cost-effective communication, such as patient condition reporting, medication consulting, physicians connecting to share expertise to improve point of care.

Extra-articular hip impingement can be the result of psoas impingement (PI), subspine impingement (SSI), ischiofemoral impingement (IFI), and greater trochanteric/pelvic impingement (GTPI). Symptoms may be due to bony abutment or soft-tissue irritation, and often, it is a challenge to differentiate among symptoms preoperatively. Currently, the clinical picture and diagnostic criteria are still being refined for these conditions. This systematic review was conducted to examine each condition and elucidate the indications for, treatment options for, and clinical outcomes of surgical management. We searched online databases (Medline, Embase, and PubMed) for English-language clinical studies published from database inception through December 31, 2013, addressing the surgical treatment of PI, SSI, IFI, and GTPI. For each condition, 2 independent assessors reviewed eligible studies. Descriptive statistics are presented. Overall, 9,521 studies were initially retrieved; ultimately, 14 studies were included examining 333 hips. For PI, arthroscopic surgery resulted in 88% of patients achieving good to excellent results, as well as significant improvements in the Harris Hip Score (P = .008), Hip Outcome Score-Activities of Daily Living (P = .02), and Hip Outcome Score-Sport (P = .04). For SSI, arthroscopic decompression, with no major complications, resulted in a mean 18.5° improvement in flexion range of motion, as well as improvements in pain (mean visual analog scale score of 5.9 points preoperatively and 1.2 points postoperatively) and the modified Harris Hip Score (mean of 64.97 points preoperatively and 91.3 points postoperatively). For both IFI and GTPI, open procedures anecdotally improved patient symptoms, with no formal objective outcomes data reported. This review suggests that there is some evidence to support that surgical treatment, by arthroscopy for PI and SSI and by open surgery for IFI and GTPI, results in improved patient outcomes.

Mistletoe in conventional oncological practice: exemplary cases.

PubMed

Legnani, Walter

2008-09-01

Mistletoe therapy, a cancer treatment suggested by Rudolf Steiner in 1920, is a typical and specific anthroposophic therapy, but could become more important today in the field of mainstream medicine. This article analyzes some of the most typical effects of mistletoe therapy based on the experience of more than 100 cases. A few patients were chosen who appear exemplary of the opportunities offered by mistletoe therapy. Their clinical history demonstrates an improvement in clinical condition and performance status, better quality of life, improved psychological status, reduction of infective events, better tolerance of concomitant chemoradiotherapy, and even a direct reduction of tumor size. The conclusion is that the patients may be indicative for future prospective clinical studies designed to confirm a real efficacy of mistletoe in cancer therapy.

Young people (aged 16-24 years) with long-term health conditions can disengage from health services, resulting in poor health outcomes, but clinicians in the UK National Health Service (NHS) are using digital communication to try to improve engagement. Evidence of effectiveness of this digital communication is equivocal. There are gaps in evidence as to how it might work, its cost, and ethical and safety issues. Our objective was to understand how the use of digital communication between young people with long-term conditions and their NHS specialist clinicians changes engagement of the young people with their health care; and to identify costs and necessary safeguards. We conducted mixed-methods case studies of 20 NHS specialist clinical teams from across England and Wales and their practice providing care for 13 different long-term physical or mental health conditions. We observed 79 clinical team members and interviewed 165 young people aged 16-24 years with a long-term health condition recruited via case study clinical teams, 173 clinical team members, and 16 information governance specialists from study NHS Trusts. We conducted a thematic analysis of how digital communication works, and analyzed ethics, safety and governance, and annual direct costs. Young people and their clinical teams variously used mobile phone calls, text messages, email, and voice over Internet protocol. Length of clinician use of digital communication varied from 1 to 13 years in 17 case studies, and was being considered in 3. Digital communication enables timely access for young people to the right clinician at the time when it can make a difference to how they manage their health condition. This is valued as an addition to traditional clinic appointments and can engage those otherwise disengaged, particularly at times of change for young people. It can enhance patient autonomy, empowerment and activation. It challenges the nature and boundaries of therapeutic relationships but can improve trust. The clinical teams studied had not themselves formally evaluated the impact of their intervention. Staff time is the main cost driver, but offsetting savings are likely elsewhere in the health service. Risks include increased dependence on clinicians, inadvertent disclosure of confidential information, and communication failures, which are mostly mitigated by young people and clinicians using common-sense approaches. As NHS policy prompts more widespread use of digital communication to improve the health care experience, our findings suggest that benefit is most likely, and harms are mitigated, when digital communication is used with patients who already have a relationship of trust with the clinical team, and where there is identifiable need for patients to have flexible access, such as when transitioning between services, treatments, or lived context. Clinical teams need a proactive approach to ethics, governance, and patient safety. ©Frances Griffiths, Carol Bryce, Jonathan Cave, Melina Dritsaki, Joseph Fraser, Kathryn Hamilton, Caroline Huxley, Agnieszka Ignatowicz, Sung Wook Kim, Peter K Kimani, Jason Madan, Anne-Marie Slowther, Mark Sujan, Jackie Sturt.

To investigate the effectiveness of psychological therapy in reducing psychological distress for adults with autism spectrum conditions (ASC) and co-morbid mental health conditions in routine clinical practice. To explore the effect of individual characteristics and service factors on change in general distress. In a specialist psychological therapies service for adults with ASC, the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) self-report questionnaire of psychological distress is completed by clients at start and end of therapy. Change over time and reliable and clinical change was assessed for 81 of a total of 122 clients (66.4%). Factors which may influence change over time were explored using available clinical information. Overall, there was a significant reduction in CORE-OM score during therapy with a small effect size. Most clients showed an improvement in psychological distress over therapy (75.4% improved, with 36.9% of these showing reliable changes). Significant and comparable reductions from pre-therapy to post-therapy were seen across the sample, showing that individual differences did not mediate therapy effectiveness. CORE-OM scores mediate the association between age of ASD diagnosis and hours of therapeutic input required, with greater age at diagnosis and higher distress associated with longer therapy duration. Our preliminary findings suggest that psychological therapy may be effective in reducing general distress for clients with ASC and co-morbid mental health conditions and should be routinely offered. Individuals who are diagnosed with ASD in adulthood are likely to require a longer course of therapy when their general distress scores are high. Copyright © 2017 John Wiley & Sons, Ltd.

To act or not to act: responses to electronic health record prompts by family medicine clinicians.

A major focus of health care today is a strong emphasis on improving the health and quality of care for entire patient populations. One common approach utilizes electronic clinical alerts to prompt clinicians when certain interventions are due for individual patients being seen. However, these alerts have not been consistently effective, particularly for less visible (though important) conditions such as hearing loss (HL) screening. We conducted hour-long cognitive task analysis interviews to explore how family medicine clinicians view, perceive, and use electronic clinical alerts, and to utilize this information to design a more effective alert using HL identification and referral as a model diagnosis. Four key direct barriers were identified that impeded alert use: poor standardization and formatting, time pressures in primary care, clinic workflow variations, and mental models of the condition being prompted (in this case, HL). One indirect barrier was identified: electronic health record and institution/government regulations. We identified that clinicians' mental model of the condition being prompted was probably the major barrier, though this was often expressed as time pressure. We discuss solutions to each of the 5 identified barriers, such as addressing physicians' mental models, by focusing on physicians' expertise rather than knowledge to improve their comfort when caring for patients with the conditions being prompted. To unleash the potential of electronic clinical alerts, electronic health record and health care institutions need to address some key barriers. We outline these barriers and propose solutions. © The Author 2017. Published by Oxford University Press on behalf of the American Medical Informatics Association. All rights reserved.

The high occurrence and under-treatment of clinical depression and behavioral and psychological symptoms of dementia (BPSD) within aged care settings is concerning, yet training programs aimed at improving the detection and management of these problems have generally been ineffective. This article presents a study protocol to evaluate a training intervention for facility managers/registered nurses working in aged care facilities that focuses on organisational processes and culture as well as knowledge, skills and self-efficacy. A Randomised Control Trial (RCT) will be implemented across 18 aged care facilities (divided into three conditions). Participants will be senior registered nurses and personal care attendants employed in the aged care facility. The first condition will receive the training program (Staff as Change Agents - Enhancing and Sustaining Mental Health in Aged Care), the second condition will receive the training program and clinical support, and the third condition will receive no intervention. Pre-, post-, 6-month and 12-month follow-up measures of staff and residents will be used to demonstrate how upskilling clinical leaders using our transformational training approach, as well as the use of a structured screening, referral and monitoring protocol, can address the mental health needs of older people in residential care. The expected outcome of this study is the validation of an evidence-based training program to improve the management of depression and BPSD among older people in residential care settings by establishing routine practices related to mental health. This relatively brief but highly focussed training package will be readily rolled out to a larger number of residential care facilities at a relatively low cost.

Children with autism have heightened risk of developing oral health problems. Interventions targeting at-home oral hygiene habits may be the most effective means of improving oral hygiene outcomes in this population. This randomized control trial examined the effectiveness of a 3-week video-modeling brushing intervention delivered to patients over the internet. Eighteen children with autism were assigned to an Intervention or Control video condition. Links to videos were delivered via email twice daily. Blind clinical examiners provided plaque index ratings at baseline, midpoint, and endpoint. Results show oral hygiene improvements in both groups, with larger effect sizes in the Intervention condition. The findings provide preliminary support for the use of internet-based interventions to improve oral hygiene for children with autism.

Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (i.e., chronic post-surgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (i.e., surgery, viral infection, injury, and toxic/noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

Weathering the storm: Improving therapeutic interventions for cytokine storm syndromes by targeting disease pathogenesis.

PubMed

Weaver, Lehn K; Behrens, Edward M

2017-03-01

Cytokine storm syndromes require rapid diagnosis and treatment to limit the morbidity and mortality caused by the hyperinflammatory state that characterizes these devastating conditions. Herein, we discuss the current knowledge that guides our therapeutic decision-making and personalization of treatment for patients with cytokine storm syndromes. Firstly, ICU-level supportive care is often required to stabilize patients with fulminant disease while additional diagnostic evaluations proceed to determine the underlying cause of cytokine storm. Pharmacologic interventions should be focused on removing the inciting trigger of inflammation and initiation of an individualized immunosuppressive regimen when immune activation is central to the underlying disease pathophysiology. Monitoring for a clinical response is required to ensure that changes in the therapeutic regimen can be made as clinically warranted. Escalation of immunosuppression may be required if patients respond poorly to the initial therapeutic interventions, while a slow wean of immunosuppression in patients who improve can limit medication-related toxicities. In certain scenarios, a decision must be made whether an individual patient requires hematopoietic cell transplantation to prevent recurrence of disease. Despite these interventions, significant morbidity and mortality remains for cytokine storm patients. Therefore, we use this review to propose a clinical schema to guide current and future attempts to design rational therapeutic interventions for patients suffering from these devastating conditions, which we believe speeds the diagnosis of disease, limits medication-related toxicities, and improves clinical outcomes by targeting the heterogeneous and dynamic mechanisms driving disease in each individual patient.

The Effectiveness of Self-Management Mobile Phone and Tablet Apps in Long-term Condition Management: A Systematic Review.

PubMed

Whitehead, Lisa; Seaton, Philippa

2016-05-16

Long-term conditions and their concomitant management place considerable pressure on patients, communities, and health care systems worldwide. International clinical guidelines on the majority of long-term conditions recommend the inclusion of self-management programs in routine management. Self-management programs have been associated with improved health outcomes; however, the successful and sustainable transfer of research programs into clinical practice has been inconsistent. Recent developments in mobile technology, such as mobile phone and tablet computer apps, could help in developing a platform for the delivery of self-management interventions that are adaptable, of low cost, and easily accessible. We conducted a systematic review to assess the effectiveness of mobile phone and tablet apps in self-management of key symptoms of long-term conditions. We searched PubMed, Embase, EBSCO databases, the Cochrane Library, and The Joanna Briggs Institute Library for randomized controlled trials that assessed the effectiveness of mobile phone and tablet apps in self-management of diabetes mellitus, cardiovascular disease, and chronic lung diseases from 2005-2016. We searched registers of current and ongoing trials, as well as the gray literature. We then checked the reference lists of all primary studies and review papers for additional references. The last search was run in February 2016. Of the 9 papers we reviewed, 6 of the interventions demonstrated a statistically significant improvement in the primary measure of clinical outcome. Where the intervention comprised an app only, 3 studies demonstrated a statistically significant improvement. Interventions to address diabetes mellitus (5/9) were the most common, followed by chronic lung disease (3/9) and cardiovascular disease (1/9). A total of 3 studies included multiple intervention groups using permutations of an intervention involving an app. The duration of the intervention ranged from 6 weeks to 1 year, and final follow-up data ranged from 3 months to 1 year. Sample size ranged from 48 to 288 participants. The evidence indicates the potential of apps in improving symptom management through self-management interventions. The use of apps in mHealth has the potential to improve health outcomes among those living with chronic diseases through enhanced symptom control. Further innovation, optimization, and rigorous research around the potential of apps in mHealth technology will move the field toward the reality of improved health care delivery and outcomes.

Beyond Readability: Investigating Coherence of Clinical Text for Consumers

PubMed Central

Hetzel, Scott; Dalrymple, Prudence; Keselman, Alla

2011-01-01

Background A basic tenet of consumer health informatics is that understandable health resources empower the public. Text comprehension holds great promise for helping to characterize consumer problems in understanding health texts. The need for efficient ways to assess consumer-oriented health texts and the availability of computationally supported tools led us to explore the effect of various text characteristics on readers’ understanding of health texts, as well as to develop novel approaches to assessing these characteristics. Objective The goal of this study was to compare the impact of two different approaches to enhancing readability, and three interventions, on individuals’ comprehension of short, complex passages of health text. Methods Participants were 80 university staff, faculty, or students. Each participant was asked to “retell” the content of two health texts: one a clinical trial in the domain of diabetes mellitus, and the other typical Visit Notes. These texts were transformed for the intervention arms of the study. Two interventions provided terminology support via (1) standard dictionary or (2) contextualized vocabulary definitions. The third intervention provided coherence improvement. We assessed participants’ comprehension of the clinical texts through propositional analysis, an open-ended questionnaire, and analysis of the number of errors made. Results For the clinical trial text, the effect of text condition was not significant in any of the comparisons, suggesting no differences in recall, despite the varying levels of support (P = .84). For the Visit Note, however, the difference in the median total propositions recalled between the Coherent and the (Original + Dictionary) conditions was significant (P = .04). This suggests that participants in the Coherent condition recalled more of the original Visit Notes content than did participants in the Original and the Dictionary conditions combined. However, no difference was seen between (Original + Dictionary) and Vocabulary (P = .36) nor Coherent and Vocabulary (P = .62). No statistically significant effect of any document transformation was found either in the open-ended questionnaire (clinical trial: P = .86, Visit Note: P = .20) or in the error rate (clinical trial: P = .47, Visit Note: P = .25). However, post hoc power analysis suggested that increasing the sample size by approximately 6 participants per condition would result in a significant difference for the Visit Note, but not for the clinical trial text. Conclusions Statistically, the results of this study attest that improving coherence has a small effect on consumer comprehension of clinical text, but the task is extremely labor intensive and not scalable. Further research is needed using texts from more diverse clinical domains and more heterogeneous participants, including actual patients. Since comprehensibility of clinical text appears difficult to automate, informatics support tools may most productively support the health care professionals tasked with making clinical information understandable to patients.

Problem Most patients with advanced lung cancer currently receive much of their health care, including chemotherapy, as outpatients. Patients have to deal with the complex and time consuming logistics of ambulatory cancer care. At the same time, members of staff often waste considerable time and energy in organisational aspects of care that could be better used in direct interaction with patients. Design Quality improvement study using direct observation and run and flow charts, and focus group meetings with patients and families regarding perceptions of the clinic and with staff regarding satisfaction with working conditions. Setting Thoracic oncology outpatient clinic at a Norwegian university hospital where patients receive chemotherapy and complementary palliative care. Key measures for improvement Waiting time and time wasted during consultations; calmer working situation at the clinic; satisfaction among patients. Strategies for change Rescheduled patients' appointments, automated retrieval of blood test results, systematic reporting in patients' files, design of an information leaflet, and refurnishing of the waiting area at the clinic. Effects of change Interventions resulted in increased satisfaction for patients and staff, reduced waiting time, and reduced variability of waiting time. Lessons learnt Direct observation, focus groups, questionnaires on patients' satisfaction, and measurement of process time were useful in systematically improving care in this outpatient clinic. The description of this experience can serve as an example for the improvement of a microsystem, particularly in other settings with similar problems. PMID:15933354

A primary objective of accountable care is to support providers in reforming care to improve outcomes and lower costs. Gaps in accountable care measure sets may cause missed opportunities for improvement and missed signals of problems in care. Measures to balance financial incentives may be particularly important for high-cost conditions or specialty treatments. This study explored gaps in measure sets for specific conditions and offers strategies for more comprehensive measurement that do not necessarily require more measures. A descriptive analysis of measure gaps in accountable care programs and proposed solutions for filling the gaps. We analyzed gaps in 2 accountable care organization measure sets for 20 high-priority clinical conditions by comparing the measures in those sets with clinical guidelines and assessing the use of outcome measures. Where we identified gaps, we looked for existing measures to address the gaps. Gaps not addressed by existing measures were considered areas for measure development or measurement strategy refinement. We found measure gaps across all 20 conditions, including those conditions that are commonly addressed in current measure sets. In addition, we found many gaps that could not be filled by existing measures. Results across all 20 conditions informed recommendations for measure set improvement. Addressing all gaps in accountable care measure sets with more of the same types of measures and approaches to measurement would require an impractical number of measures and would miss the opportunity to use better measures and innovative approaches. Strategies for effectively filling measure gaps include using preferred measure types such as cross-cutting, outcome, and patient-reported measures. Program implementers should also apply new approaches to measurement, including layered and modular models.

To assess the effect of wet cupping on health-related quality of life (HRQOL) of adult patients with chronic medical conditions, who were referred to the Cupping Clinic of King Abdulaziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia. Methods: A controlled, quasi-experimental study design was carried out among 629 patients referred for cupping from the KAUH Specialty Clinics, during the period from January to December 2014. Patients in the intervention group (309 patients) completed a pre-test included WHO quality of life-BREF, received one wet-cupping session, and filled-out the post-test (1 month later). Patients in the control group (320 patients) completed the pre-test during their enrollment in the study and post-test one month later. Both groups received their ordinary treatment. Descriptive and inferential statistics were performed.  Results: Pain was the most common cause for cupping referral. After cupping intervention, the mean scores of most of the HRQOL domains, especially the physical domain, improved significantly among patients in the intervention group. The mean total score of physical HRQOL domain was 61.6 ± 13.6 before cupping, and reached 69.7 ± 12.6 after intervention (paired t-test=11.3, p=0.000). Improvements in HRQOL were noticed for almost all types of pain and other medical conditions.  Conclusion: There are promising effects in favor of using wet cupping for improving HRQOL of patients with chronic conditions. Cupping is recommended as a complementary treatment modality for chronic medical conditions, especially pain.

With age, the prevalence of musculoskeletal conditions increases markedly. This rural-based study determined the benefits of two approaches for managing musculoskeletal conditions: a multiple-component 'Self-management Plus' intervention, and usual care. The intervention combined self-management education with physical activity and health professional support. 6-month outcomes included: Clinical Global Impression-Improvement Scale (CGI-IS) and Quality of Life (QoL). A total of 145 people were recruited; mean (SD) age was 66.1 (11.1) and 63.3 (10.9) years for intervention and control groups respectively. The intervention resulted in greater improvements in global functioning (CGI-IS mean (SD) = 3.2 (1.3)) than usual care (CGI-IS mean (SD) = 4.2 (1.5)). There was no difference in QoL improvement between study groups. A multiple-component 'Self-management Plus' intervention had a positive effect on physical functioning for older adults with musculoskeletal conditions. However, recruitment and retention of participants was problematic, which raises questions about the intervention's feasibility in its current form.

2004-05-01

To conduct a group-randomized clinical trial to determine whether regular feedback to primary care providers of synthesized information on patients' health, function, and satisfaction would demonstrate improved outcomes for their patients with diabetes. Patients in General Internal Medicine Clinics Department of Veterans Affairs (VA) Medical Centers were randomized into seven intervention or control firms. Patient self-reported information was collected by mail on general health, diabetes, and up to five other chronic conditions. Patients with diabetes received the Seattle Diabetes Questionnaire, the 36-item Medical Outcomes Study short form (SF-36), and a validated patient satisfaction questionnaire at regular intervals. Data from self-report, clinical, pharmacy, and laboratory sources were synthesized into patient-specific feedback reports that intervention providers received before patients' visits. The timely delivery to primary care providers of state-of-the-art patient-feedback reports that identified patient issues and areas for improvement did not result in significant improvements in patient outcomes between the intervention and control firms. Outcomes in diabetic patients whose providers received synthesized patient data before visits were no better than in those receiving care from control firms. Future studies may benefit from substantial involvement in patients discussing, problem solving, and goal setting in addition to use of timely synthesized patient data.

Andrzejewski, M E; Kirby, K C; Morral, A R; Iguchi, M Y

2001-07-01

After drug treatment counselors at a community-based methadone treatment clinic were trained in implementing a contingency management (CM) intervention, baseline measures of performance revealed that, on average, counselors were meeting the performance criteria specified by the treatment protocol about 42% of the time. Counselors were exposed to graphical feedback and a drawing for cash prizes in an additive within-subjects design to assess the effectiveness of these interventions in improving protocol adherence. Counselor performance measures increased to 71% during the graphical feedback condition, and to 81% during the drawing. Each counselor's performance improved during the intervention conditions. Additional analyses suggested that counselors did not have skill deficits that hindered implementation. Rather, protocol implementation occurred more frequently when consequences were added, thereby increasing the overall proportion of criteria met. Generalizations, however, may be limited due to a small sample size and possible confounding of time and intervention effects. Nonetheless, present results show promise that feedback and positive reinforcement could be used to improve technology transfer of behavioral interventions into community clinic settings.

The objective of this study was to compare the relative effectiveness of two modes of delivering Behavioral Family Systems Therapy for Diabetes (BFST-D) to improve adherence and glycemic control among adolescents with type 1 diabetes with suboptimal glycemic control (HbA(1c) ≥9.0% [≥74.9 mmol/mol]): face to face in clinic (Clinic) and Internet videoconferencing (Skype) conditions. Adolescents aged 12 to 18 years and at least one adult caregiver were randomized to receive BFST-D via the Clinic or Skype condition. Participants completed up to 10 therapy sessions within a 12-week period. Changes in youth- and parent-reported adherence and glycemic control were compared before and after the intervention and at follow-up assessment. Using an intent-to-treat analytic approach, no significant between-group differences were identified between the before, after, and follow-up assessments. Groups were collapsed to examine the overall effects of BFST-D on adherence and glycemic control. Results identified that statistically significant improvements in adherence and glycemic control occurred from before to after the intervention; improvements were maintained at 3-month follow-up. Delivery of BFST-D via Internet-based videoconferencing is viable for addressing nonadherence and suboptimal glycemic control in adolescents with type 1 diabetes, potentially reducing important barriers to care for youth and families. © 2015 by the American Diabetes Association.

2016-09-01

Mindfulness-based interventions have been increasingly utilized in the management of chronic pain since 1982. This second review of a two-part series evaluates the efficacy, mechanism, and safety of mindfulness meditation for chronic pain, substance use disorder, tobacco use disorder, and insomnia frequently co-occurring after return from deployment. Standard databases were searched until August 4, 2015. 72 relevant systematic reviews and clinical trials met the inclusion criteria. The Strength of Recommendation Taxonomy was used to assess the quality of individual studies and to rate the strength of recommendation (SOR) for each clinical condition. Mindfulness-based interventions effectively and durably reduce pain intensity, improve functional status, pain-related psychological consequences, quality of life (SOR B). They can also be utilized as an adjunctive intervention aimed at improving health-related quality of life in individuals with substance use disorders interested in self-management strategies (SOR B). Mindfulness training for smokers used adjunctively with pharmacotherapy shows efficacy in maintaining abstinence comparable to that of the current standard of care (SOR B). Future large, well-designed randomized clinical trials using active controls in service members and veterans with co-occurring pain and psychological health conditions are necessary to provide more precise clinical guidance.

Dandruff is a common scalp disorder affecting almost half of the post-pubertal population of any ethnicity and both genders. It is one of the major reasons for patients to consult a dermatologist and it is the cause of significant psychological and social distress. The aim of this open study was to evaluate the benefit of a 4-week treatment with a shampoo containing 0.1% lipohydroxyacid (LHA) and 1.3% salicylic acid on the scalp condition and on the quality of life of 275 volunteers with seborrheic dermatitis (SD) (n = 226) or light-to-moderate scalp psoriasis (SP) (n = 49). The clinical benefit of the treatment was assessed by scoring the following parameters, i.e., severity of the dermatosis, scaling, itching, excoriations, and superficial burning sensation. The impact on the quality of life was assessed using the Scalpdex, a questionnaire specially developed by Chen et al. for patients with scalp dermatitis, which includes 23 questions regarding the symptoms, functioning and emotions affected by scalp dermatosis. The shampoo used in this study was well tolerated. After a 4-week treatment, dermatologists noticed a significant clinical improvement of all the scalp parameters evaluated (i.e., the composite lesional score was improved in 91% and 77% of the patients with SD or SP respectively). The symptoms, functioning and emotions scores of quality of life were also significantly improved in relation to the improvement of scalp condition. This study not only allowed a better understanding of the SD and SP patient's profile but also demonstrated that the shampoo evaluated is a convenient, efficient, safe, and well-tolerated cosmetic treatment of SD and light-to-moderate SP improving greatly the quality of life of the treated patients.

This study assessed the effect of a 12-week sports-based exercise intervention on glucose regulation, anthropometry and inflammatory markers associated with the prevalence of type 2 diabetes mellitus (T2DM) in Indigenous Australian men. Twenty-six inactive Indigenous Australian men (48.6±6.6 years) were randomized into exercise (n=16) or control (n=10)conditions. Training included ∼2-3 days/week for 12 weeks of sports and gym exercises in a group environment, whilst control participants maintained normal activity and dietary patterns. Pre- and post-intervention testing included: anthropometry, peak aerobic capacity, fasting blood chemistry of inflammatory cytokines, adiponectin, leptin, cholesterol, glucose, insulin and C-peptide. An oral glucose tolerance test measured glucose, insulin and C-peptide 30, 60, 90 and 120min post 75g glucose ingestion. The exercise condition decreased insulin area under the curve (25±22%), increased estimated insulin sensitivity (35±62%) and decreased insulin resistance (9±35%; p<0.05), compared with control (p>0.05). The exercise condition decreased in body mass index, waist circumference and waist to hip ratio (p<0.05), compared to control (p>0.05). Leptin decreased in the exercise group, with no changes for adiponectin (p>0.05) or inflammatory markers (p>0.05) in either condition. Aerobic fitness variables showed significant increases in peak oxygen consumption for the exercise condition compared to no change in control (p>0.05). Findings indicate positive clinical outcomes in metabolic, anthropometric and aerobic fitness variables. This study provides evidence for sport and group-based activities leading to improved clinical risk factors associated with T2DM development in clinically obese Indigenous Australian men.

Diabetes is a chronic condition that is one of the major causes of illness, disability, and death in Malaysia. Cost in managing diabetes plus indirect cost of lost work, pain, and suffering have all increased. The optimal management of patients with diabetes require the tracking of patients over time to monitor the progression of the disease, compliance with treatment, and preventive care. Diabetes care can be improved by standardizing access to, and improving the use of, clinical information. Access to timely, accurate and well-organized electronic data will improve the quality of care for patients with diabetes. Clinical Research Center convened an expert workshop to forecast how physicians, hospitals and clinics will employ clinical information technology (IT) applications to diabetes care over the next year. Workshop participants included experts from research organizations, government, and the IT vendor. This is a summary of the workshop organised for the purpose of the Audit of Diabetes Control and Management (ADCM) project. We hope to identify the gaps, if any, that exists in delivering diabetes care and to improve the quality of care. In future, we hope to develop an expansion of this project for the Adult Diabetes Registry that will be implemented for the whole country.

Common social cognitive impairments do not mean common causes: A commentary on Cotter et al. (2018).

PubMed

Dodell-Feder, David; Germine, Laura T

2018-06-06

Many clinical conditions, ranging from psychiatric to neurodegenerative illnesses, are associated with impairments in the processes by which we perceive, interpret, and respond to social information; a suite of abilities known as social cognition. Through a systematic review of meta-analyses, Cotter et al. (2018) present a compelling view of social cognitive deficits as a core phenotype of many clinical conditions. However, we caution against one potential interpretation of their findings, namely, that similar social cognitive outcomes are produced by similar causes. Specifically, we argue that while the outcome may look similar across clinical conditions (i.e., global social cognitive deficits), the cause and nature of those impairments are likely to differ, and, as a consequence, so too will its remediation. We advocate for the development of better methods for assessing social cognition, which may speak to the varying nature of social cognitive impairment across conditions. Ultimately, a better understanding of how social cognition is impaired will facilitate the development of more targeted, more effective treatments, that will improve patient care.

We examined the efficacy of including a research intermediary (RI) during the consent process in reducing participants' perceptions of coercion to enroll in a research study. Eighty-four drug court clients being recruited into an ongoing study were randomized to receive a standard informed consent process alone (standard condition) or with an RI (intermediary condition). Before obtaining consent, RIs met with clients individually to discuss remaining concerns. Findings provided preliminary evidence that RIs reduced client perceptions that their participation might influence how clinical and judicial staff view them. This suggests that using RIs may improve participant autonomy in clinical studies.

Dry eye syndrome is one of the most commonly reported eye health conditions. Dynamic-area high-speed videokeratoscopy (DA-HSV) represents a promising alternative to the most invasive clinical methods for the assessment of the tear film surface quality (TFSQ), particularly as Placido-disk videokeratoscopy is both relatively inexpensive and widely used for corneal topography assessment. Hence, improving this technique to diagnose dry eye is of clinical significance and the aim of this work. First, a novel ray-tracing model is proposed that simulates the formation of a Placido image. This model shows the relationship between tear film topography changes and the obtained Placido image and serves as a benchmark for the assessment of indicators of the ring's regularity. Further, a novel block-feature TFSQ indicator is proposed for detecting dry eye from a series of DA-HSV measurements. The results of the new indicator evaluated on data from a retrospective clinical study, which contains 22 normal and 12 dry eyes, have shown a substantial improvement of the proposed technique to discriminate dry eye from normal tear film subjects. The best discrimination was obtained under suppressed blinking conditions. In conclusion, this work highlights the potential of the DA-HSV as a clinical tool to diagnose dry eye syndrome.

Duchenne and Becker muscular dystrophy in adolescents: current perspectives

Andrews, Jennifer G; Wahl, Richard A

2018-01-01

Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are life-limiting and progressive neuromuscular conditions with significant comorbidities, many of which manifest during adolescence. BMD is a milder presentation of the condition and much less prevalent than DMD, making it less represented in the literature, or more severely affected individuals with BMD may be subsumed into the DMD population using clinical cutoffs. Numerous consensus documents have been published on the clinical management of DMD, the most recent of which was released in 2010. The advent of these clinical management consensus papers, particularly respiratory care, has significantly increased the life span for these individuals, and the adolescent years are now a point of transition into adult lives, rather than a period of end of life. This review outlines the literature on DMD and BMD during adolescence, focusing on clinical presentation during adolescence, impact of living with a chronic illness on adolescents, and the effect that adolescents have on their chronic illness. In addition, we describe the role that palliative-care specialists could have in improving outcomes for these individuals. The increasing proportion of individuals with DMD and BMD living into adulthood underscores the need for more research into interventions and intracacies of adolescence that can improve the social aspects of their lives.

Evidences have shown that physiotherapy programs may improve the balance of individuals with Parkinson's disease (PD), although it is not clear which specific exercise program is better. The aim of this study was to compare the effectiveness of balance versus resistance training on postural control measures in PD patients. Randomized controlled trial. The study was conducted in a physiotherapy outpatient clinic of a university hospital. A total of 40 PD participants were randomly divided into two groups: balance training (BT) and resistance training (RT). The BT group focused on balance training, functional independence and gait while the RT group performed resistance exercises emphasizing the lower limbs and trunk, both supervised by trained physiotherapists. Therapy sessions were held twice a week (at 60 minutes), totaling 24 sessions. The primary outcome was evaluated by force platform with center of pressure sway measures in different balance conditions and the secondary outcome was evaluated by Balance Evaluation Systems Test (BESTest) scale to determine the effects of the intervention on postural control. Significant improvement of postural control (pre vs. post 15.1 vs. 9.6 cm2) was only reported in favor of BT group (d=1.17) for one-legged stand condition on force platform. The standardized mean difference between groups was significantly (P<0.02), with 36% of improvement for BT vs. 0.07% for RT on this condition. Significant improvement (P<0.05) was also observed in favor of BT (in mean 3.2%) for balance gains in some BESTest scores, when compared to RT group (-0.98%). Postural control in Parkinson's disease is improved when training by a directional and specific balance program than a resistance training program. Balance training is superior to resistance training in regard to improving postural control of individuals with PD. Gold standard instruments (high in cost and difficult to access) were used to assess balance, as well as scales with clinical applicability (low cost, easily acceptable, applicable and valid), which can guide the management of physiotherapists both in their decision-making and in clinical practice.

Implementing an intravenous insulin protocol in your practice: practical advice to overcome clinical, administrative, and financial barriers.

PubMed

Kelly, Janet L; Hirsch, Irl B; Furnary, Anthony P

2006-01-01

Diabetes mellitus is the fourth most common comorbid condition among hospitalized patients, and 30% of patients undergoing open-heart surgery have diabetes. The link between hyperglycemia and poor outcome has been well described, and large clinical trials have shown that aggressive control of blood glucose with an insulin infusion can improve these outcomes. The barriers to implementing an insulin infusion protocol are numerous, despite the fact that doing so is paramount to clinical success. Barriers include safety concerns, such as fear of hypoglycemia, insufficient nursing staff to patient ratios, lack of administrative and physician support, various system and procedural issues, and resistance to change. Key steps to overcome the barriers include building support with multidisciplinary champions, involving key staff, educating staff, and administrators of the clinical and economic benefits of improving glycemic control, setting realistic goals, selecting a validated insulin infusion protocol, and internally marketing the success of the protocol.

Mindfulness training alters emotional memory recall compared to active controls: support for an emotional information processing model of mindfulness.

While mindfulness-based interventions have received widespread application in both clinical and non-clinical populations, the mechanism by which mindfulness meditation improves well-being remains elusive. One possibility is that mindfulness training alters the processing of emotional information, similar to prevailing cognitive models of depression and anxiety. The aim of this study was to investigate the effects of mindfulness training on emotional information processing (i.e., memory) biases in relation to both clinical symptomatology and well-being in comparison to active control conditions. Fifty-eight university students (28 female, age = 20.1 ± 2.7 years) participated in either a 12-week course containing a "meditation laboratory" or an active control course with similar content or experiential practice laboratory format (music). Participants completed an emotional word recall task and self-report questionnaires of well-being and clinical symptoms before and after the 12-week course. Meditators showed greater increases in positive word recall compared to controls [F(1, 56) = 6.6, p = 0.02]. The meditation group increased significantly more on measures of well-being [F(1, 56) = 6.6, p = 0.01], with a marginal decrease in depression and anxiety [F(1, 56) = 3.0, p = 0.09] compared to controls. Increased positive word recall was associated with increased psychological well-being (r = 0.31, p = 0.02) and decreased clinical symptoms (r = -0.29, p = 0.03). Mindfulness training was associated with greater improvements in processing efficiency for positively valenced stimuli than active control conditions. This change in emotional information processing was associated with improvements in psychological well-being and less depression and anxiety. These data suggest that mindfulness training may improve well-being via changes in emotional information processing. Future research with a fully randomized design will be needed to clarify the possible influence of self-selection.

To evaluate the impact of a physical activity intervention consisting of telephone counseling with home-based monitoring to improve fatigue and depression in individuals with multiple sclerosis (MS). Single-blind randomized controlled trial. Sixty-four individuals with MS received either telephone counseling (N = 31), or self-directed physical activity education (N = 33). The education condition (EC) consisted of advice to increase physical activity and a DVD with examples of in-home exercises for multiple physical ability levels. The telephone counseling condition (TC) included EC as well as mailed graphic feedback, 6 telephone counseling sessions using principles of motivational interviewing, and telehealth home monitoring to track progress on physical activity goals. Booster sessions were provided when participants indicated they did not meet their goals. Assessment was conducted at baseline, 3-month, and 6-month follow-up. TC participants reported significantly reduced fatigue (d = -.70), reduced depression (d = -.72) and increased physical activity (d = .92) relative to EC participants. Of individuals receiving TC, 33.3% experienced clinically significant improvement in fatigue (vs. 18.2% in EC) and 53.3% experienced clinically significant improvement in depression (vs. 9.1% in EC). Improvements in physical activity mediated improvements in fatigue with a similar trend for depression. TC was highly feasible (participants completed 99.5% of schedule telephone sessions) and well tolerated (100% rated it highly successful). Telephone-based counseling with home monitoring is a promising modality to improve physical activity and treat fatigue and depression. (c) 2016 APA, all rights reserved).

Retinal diseases generally are vision-threatening conditions that warrant appropriate clinical decision-making which currently solely dependents upon extensive clinical screening by specialized ophthalmologists. In the era where molecular assessment has improved dramatically, we aimed at the identification of biomarkers in 175 ocular fluids to classify four archetypical ocular conditions affecting the retina (age-related macular degeneration, idiopathic non-infectious uveitis, primary vitreoretinal lymphoma, and rhegmatogenous retinal detachment) with one single test. Unsupervised clustering of ocular proteins revealed a classification strikingly similar to the clinical phenotypes of each disease group studied. We developed and independently validated a parsimonious model based merely on three proteins; interleukin (IL)-10, IL-21, and angiotensin converting enzyme (ACE) that could correctly classify patients with an overall accuracy, sensitivity and specificity of respectively, 86.7%, 79.4% and 92.5%. Here, we provide proof-of-concept for molecular profiling as a diagnostic aid for ophthalmologists in the care for patients with retinal conditions.

Physically-active video games ('exergames') have recently gained popularity for leisure and entertainment purposes. Using exergames to combine physical activity and cognitively-demanding tasks may offer a novel strategy to improve cognitive functioning. Therefore, this systematic review and meta-analysis was performed to establish effects of exergames on overall cognition and specific cognitive domains in clinical and non-clinical populations. We identified 17 eligible RCTs with cognitive outcome data for 926 participants. Random-effects meta-analyses found exergames significantly improved global cognition (g=0.436, 95% CI=0.18-0.69, p=0.001). Significant effects still existed when excluding waitlist-only controlled studies, and when comparing to physical activity interventions. Furthermore, benefits of exergames where observed for both healthy older adults and clinical populations with conditions associated with neurocognitive impairments (all p<0.05). Domain-specific analyses found exergames improved executive functions, attentional processing and visuospatial skills. The findings present the first meta-analytic evidence for effects of exergames on cognition. Future research must establish which patient/treatment factors influence efficacy of exergames, and explore neurobiological mechanisms of action. Crown Copyright © 2017. Published by Elsevier Ltd.

The genetic basis for survivorship in coronary artery disease

Dungan, Jennifer R.; Hauser, Elizabeth R.; Qin, Xuejun; Kraus, William E.

2013-01-01

Survivorship is a trait characterized by endurance and virility in the face of hardship. It is largely considered a psychosocial attribute developed during fatal conditions, rather than a biological trait for robustness in the context of complex, age-dependent diseases like coronary artery disease (CAD). The purpose of this paper is to present the novel phenotype, survivorship in CAD as an observed survival advantage concurrent with clinically significant CAD. We present a model for characterizing survivorship in CAD and its relationships with overlapping time- and clinically-related phenotypes. We offer an optimal measurement interval for investigating survivorship in CAD. We hypothesize genetic contributions to this construct and review the literature for evidence of genetic contribution to overlapping phenotypes in support of our hypothesis. We also present preliminary evidence of genetic effects on survival in people with clinically significant CAD from a primary case-control study of symptomatic coronary disease. Identifying gene variants that confer improved survival in the context of clinically appreciable CAD may improve our understanding of cardioprotective mechanisms acting at the gene level and potentially impact patients clinically in the future. Further, characterizing other survival-variant genetic effects may improve signal-to-noise ratio in detecting gene associations for CAD. PMID:24143143

2018-03-01

To meet the needs of an aging population who often have multiple chronic conditions, interprofessional care is increasingly adopted by patient-centred medical homes and Accountable Care Organisations to improve patient care coordination and decrease costs in the United States, especially in underserved areas with primary care workforce shortages. In this cross-sectional survey across multiple clinical settings in an underserved area, healthcare providers perceived overall outcomes associated with interprofessional care teams as positive. This included healthcare providers' beliefs that interprofessional care teams improved patient outcomes, increased clinic efficiency, and enhanced care coordination and patient follow-up. Teams with primary care physician available each day were perceived as better able to coordinate care and follow up with patients (p = .031), while teams that included clinical pharmacists were perceived as preventing medication-associated problems (p < .0001). Healthcare providers perceived the interprofessional care model as a useful strategy to improve various outcomes across different clinical settings in the context of a shortage of primary care physicians.

To evaluate the impact of modafinil on "free" and "cued" recall of clinical information in fatigued but nonsleep-deprived clinicians. Despite attempts to minimize sleep deprivation through redesign of the roster of residents and staff surgeons, evidence suggests that fatigue remains prevalent. The wake-promoting agent modafinil improves cognition in the sleep-deprived fatigued state and may improve information recall in fatigued nonsleep-deprived clinicians. Twenty-four medical undergraduates participated in a double-blind, parallel, randomized controlled trial (modafinil-200 mg:placebo). Medication was allocated 2 hours before a 90-minute fatigue-inducing, continuous performance task (dual 2-back task). A case history memorization task was then performed. Clinical information recall was assessed as "free"(no cognitive aids) and "cued"(using aid memoirs). Open and closed cues represent information of increasing specificity to aid the recall of clinical information. Fatigue was measured objectively using the psychomotor vigilance task at induction, before and after the dual 2-back task. Modafinil decreased false starts and lapses (modafinil = 0.50, placebo = 9.83, P < .05) and improved psychomotor vigilance task performance (Decreased Performance, modafinil = 0.006, placebo = 0.098, P < .05). Modafinil improved free information recall (modafinil = 137.8, placebo = 106.0, P < .01). There was no significant difference between groups in the amount of information recalled with open (modafinil = 62.3, placebo = 52.8, P = .1) and closed cues (modafinil = 80.1, placebo = 75.9, P = .3). Modafinil attenuated fatigue and improved free recall of clinical information without improving cue-based recall under the design of our experimental conditions. Memory cues to aid retrieval of clinical information are convenient interventions that could decrease fatigue-related error without adverse effects of the neuropharmacology.

Prolotherapy for Osteoarthritis and Tendinopathy: a Descriptive Review.

PubMed

Rabago, David; Nourani, Bobby

2017-06-01

Osteoarthritis and overuse tendinopathy are common chronic conditions of high societal and patient burden. The precise etiology of pain and disability in both conditions is multifactorial and not well understood. Patients are often refractory to conservative therapy. The development of new therapeutic options in both conditions is a public health priority. Prolotherapy is an injection-based outpatient regenerative therapy for chronic musculoskeletal conditions, including osteoarthritis and tendinopathy. The authors reviewed the basic science and clinical literature associated with prolotherapy for these conditions. Systematic review, including meta-analysis, and randomized controlled trials suggest that prolotherapy may be associated with symptom improvement in mild to moderate symptomatic knee osteoarthritis and overuse tendinopathy. Although the mechanism of action is not well understood and is likely multifactorial, a growing body of literature suggests that prolotherapy for knee osteoarthritis may be appropriate for the treatment of symptoms associated with knee osteoarthritis in carefully selected patients who are refractory to conservative therapy and deserves further basic and clinical science investigation for the treatment of osteoarthritis and tendinopathy.

Bipolar disorder is a common long-term mental health condition characterised by episodes of mania or hypomania and depression resulting in disability, early death, and high health and society costs. Public money funds the National Institute of Healthcare and Clinical Excellence (NICE) to produce clinical guidelines by systematically identifying the most up to date research evidence and costing its main recommendations for healthcare organisations and professionals to follow in England and Wales. Most governments, including those of England and Wales, need to improve healthcare but at reduced cost. There is evidence, particularly in bipolar disorder, that systematically following clinical guidelines achieves these outcomes. NICE clinical guidelines, including those regarding bipolar disorder, remain variably implemented. They give clinicians and patients a non-prescriptive basis for deciding their care. Despite the passing of the Health and Social Care Act in 2012 in England requiring all healthcare organisations to consider NICE clinical guidelines in commissioning, delivering, and inspecting healthcare services, healthcare organisations in the National Health Service may ignore them with little accountability and few consequences. There is no mechanism to ensure that healthcare professionals know or consider them. Barriers to their implementation include the lack of political and professional leadership, the complexity of the organisation of care and policy, mistrust of some processes and recommendations of clinical guidelines, and a lack of a clear implementation model, strategy, responsibility, or accountability. Mitigation to these barriers is presented herein. The variability, safety, and quality of healthcare might be improved and its cost reduced if the implementation of NICE clinical guidelines, such as those for bipolar disorder, were made the minimum starting point for clinical decision-making and mandatory responsibilities of all healthcare organisations and professionals.

Unmet basic resource needs, such as difficulty affording healthcare, medications, food and housing, may contribute to worse healthcare quality indicators, but interventions are hampered by lack of specific knowledge regarding the distribution of unmet basic resource needs and their association with priority clinical conditions and health service use patterns. Cross-sectional study of primary care patients in two urban academic practices from 1 October 2013 to 30 April 2014. Patients were screened for unmet needs and enrolled in a programme to link them with community resources. Key measures included patient report of unmet basic resource needs, clinical conditions prioritised by quality improvement programmes (hypertension, diabetes and depression), and health service use patterns such as frequent emergency department (ED) visits (>2 in the preceding year) and frequent clinic 'no-shows' (>1 in the preceding year). 416 patients with unmet needs were included, and compared with 2750 patients who did not report needs. The most common types of needs reported were: difficulties affording healthcare (46.5%), food (40.1%) and utilities (36.3%). Patients who reported unmet needs were more likely to have depression (17.8% vs 9.5%, p<0.0001), diabetes (32.7% vs 20.4%, p<0.0001), hypertension (54.3% vs 46.3%, p=0.002), be frequent ED users (11.3% vs 5.4%, p<0.0001), and have frequent 'no-shows' to clinic (21.6% vs 11.9%, p<0.0001). Difficulty affording healthcare and food are particularly common needs among patients with priority conditions. Strategies to identify and address unmet needs as part of routine care may be an important way to improve healthcare quality. Published by the BMJ Publishing Group Limited.

Conventional algorithms for modeling clinical events focus on characterizing the differences between patients with varying outcomes in historical data sets used for the model derivation. For many clinical conditions with low prevalence and where small data sets are available, this approach to developing models is challenging due to the limited number of positive (that is, event) examples available for model training. Here, we investigate how the approach of developing clinical models might be improved across three distinct patient populations (patients with acute coronary syndrome enrolled in the DISPERSE2-TIMI33 and MERLIN-TIMI36 trials, patients undergoing inpatient surgery in the National Surgical Quality Improvement Program registry, and patients undergoing percutaneous coronary intervention in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry). For each of these cases, we supplement an incomplete characterization of patient outcomes in the derivation data set (uncensored view of the data) with an additional characterization of the extent to which patients differ from the statistical support of their clinical characteristics (censored view of the data). Our approach exploits the same training data within the derivation cohort in multiple ways to improve the accuracy of prediction. We position this approach within the context of traditional supervised (2-class) and unsupervised (1-class) learning methods and present a 1.5-class approach for clinical decision-making. We describe a 1.5-class support vector machine (SVM) classification algorithm that implements this approach, and report on its performance relative to logistic regression and 2-class SVM classification with cost-sensitive weighting and oversampling. The 1.5-class SVM algorithm improved prediction accuracy relative to other approaches and may have value in predicting clinical events both at the bedside and for risk-adjusted quality of care assessment.

Patients with chronic conditions require frequent care visits. Problems can arise during several parts of the patient visit that decrease efficiency, making it difficult to effectively care for high volumes of patients. The purpose of the study is to test a method to improve patient visit efficiency. We used Patient Flow Analysis to identify inefficiencies in the patient visit, suggest areas for improvement, and test the effectiveness of clinic interventions. At baseline, the mean visit time for 93 anticoagulation clinic patient visits was 84 minutes (+/- 50 minutes) and the mean visit time for 25 chronic pain clinic patient visits was 65 minutes (+/- 21 minutes). Based on these data, we identified specific areas of inefficiency and developed interventions to decrease the mean time of the patient visit. After interventions, follow-up data found the mean visit time was reduced to 59 minutes (+/-25 minutes) for the anticoagulation clinic, a time decrease of 25 minutes (t-test 39%; p < 0.001). Mean visit time for the chronic pain clinic was reduced to 43 minutes (+/- 14 minutes) a time decrease of 22 minutes (t-test 34 %; p < 0.001). Patient Flow Analysis is an effective technique to identify inefficiencies in the patient visit and efficiently collect patient flow data. Once inefficiencies are identified they can be improved through brief interventions.

Conventional deep brain stimulation (DBS) utilizes regular, high frequency pulses to treat medication-refractory symptoms in essential tremor (ET). Modifications of DBS pulse shape to achieve improved effectiveness is a promising approach. The current study assessed the safety, tolerability and effectiveness of square biphasic pulse shaping as an alternative to conventional ET DBS. This pilot study compared biphasic pulses (BiP) versus conventional DBS pulses (ClinDBS). Eleven ET subjects with clinically optimized ventralis intermedius nucleus DBS were enrolled. Objective measures were obtained over 3 h while ON BiP stimulation. There was observed benefit in the Fahn-Tolosa Tremor Rating Scale (TRS) for BiP conditions when compared to the DBS off condition and to ClinDBS setting. Total TRS scores during the DBS OFF condition (28.5 IQR = 24.5-35.25) were significantly higher than the other time points. Following active DBS, TRS improved to (20 IQR = 13.8-24.3) at ClinDBS setting and to (16.5 IQR = 12-20.75) at the 3 h period ON BiP stimulation (p = 0.001). Accelerometer recordings revealed improvement in tremor at rest (χ 2  = 16.1, p = 0.006), posture (χ 2  = 15.9, p = 0.007) and with action (χ 2  = 32.1, p=<0.001) when comparing median total scores at ClinDBS and OFF DBS conditions to 3 h ON BiP stimulation. There were no adverse effects and gait was not impacted. BiP was safe, tolerable and effective on the tremor symptoms when tested up to 3 h. This study demonstrated the feasibility of applying a novel DBS waveform in the clinic setting. Larger prospective studies with longer clinical follow-up will be required. Copyright © 2017.

Cellulitis is a common and costly problem, often diagnosed in the outpatient setting. Many cutaneous conditions may clinically mimic cellulitis, but little research has been done to assess the magnitude of the problem. To determine if obtaining dermatology consultations in the outpatient primary care setting could assist in the diagnosis of pseudocellulitic conditions and reduce the rate of unnecessary antibiotic use. Nonblinded randomized clinical trial of competent adults who were diagnosed as having cellulitis by their primary care physicians (PCPs), conducted at outpatient internal medical primary care offices affiliated with a large academic medical center. Outpatient dermatology consultation. Primary outcomes were final diagnosis, antibiotic use, and need for hospitalization. A total of 29 patients (12 male and 17 female) were enrolled for participation in this trial. Nine patients were randomized to continue with PCP management (control group), and 20 patients were randomized to receive a dermatology consultation (treatment group). Of the 20 patients in the dermatology consultation group, 2 (10%) were diagnosed as having cellulitis. In the control group, all 9 patients were diagnosed as having cellulitis by PCPs, but dermatologist evaluation determined that 6 (67%) of these patients had a psuedocellulitis rather than true infection. All 9 patients (100%) in the control group were treated for cellulitis with antibiotics vs 2 patients (10%) in the treatment group (P < .001). One patient in the control group was hospitalized. All patients in the treatment group reported improvement of their cutaneous condition at the 1-week follow-up examination. Dermatology consultation in the primary care setting improves the diagnostic accuracy of suspected cellulitis and decreases unnecessary antibiotic use in patients with pseudocellulitic conditions. Obtaining an outpatient dermatology consultation may be a cost-effective strategy that improves quality of care. clinicaltrials.gov Identifier:NCT01795092.

A randomized controlled trial of brief intervention (BI), for drinking and related problems, using peer health promotion advocates (promotores), was conducted among at-risk and alcohol-dependent Mexican-origin young adult emergency department (ED) patients, aged 18-30. Six hundred and ninety-eight patients were randomized to: screened only (n = 78), assessed (n = 310) and intervention (n = 310). Primary outcomes were at-risk drinking and Rapid Alcohol Problems Screen (RAPS4) scores. Secondary outcomes were drinking days per week, drinks per drinking day, maximum drinks in a day and negative consequences of drinking. At 3- and 12-month follow-up the intervention condition showed significantly lower values or trends on all outcome variables compared to the assessed condition, with the exception of the RAPS4 score; e.g. at-risk drinking days dropped from 2.9 to 1.7 at 3 months for the assessed condition and from 3.2 to 1.2 for the intervention condition. Using random effects modeling controlling for demographics and baseline values, the intervention condition showed significantly greater improvement in all consumption measures at 12 months, but not in the RAPS4 or negative consequences of drinking. Improvements in outcomes were significantly more evident for non-injured patients, those reporting drinking prior to the event, and those lower on risk taking disposition. At 12-month follow-up this study demonstrated significantly improved drinking outcomes for Mexican-origin young adults in the ED who received a BI delivered by promotores compared to those who did not.

2015-08-04

Posttraumatic stress disorder (PTSD) is a disabling psychiatric disorder common among military personnel and veterans. First-line psychotherapies most often recommended for PTSD consist mainly of "trauma-focused" psychotherapies that involve focusing on details of the trauma or associated cognitive and emotional effects. To examine the effectiveness of psychotherapies for PTSD in military and veteran populations. PubMed, PsycINFO, and PILOTS were searched for randomized clinical trials (RCTs) of individual and group psychotherapies for PTSD in military personnel and veterans, published from January 1980 to March 1, 2015. We also searched reference lists of articles, selected reviews, and meta-analyses. Of 891 publications initially identified, 36 were included. Two trauma-focused therapies, cognitive processing therapy (CPT) and prolonged exposure, have been the most frequently studied psychotherapies for military-related PTSD. Five RCTs of CPT (that included 481 patients) and 4 RCTs of prolonged exposure (that included 402 patients) met inclusion criteria. Focusing on intent-to-treat outcomes, within-group posttreatment effect sizes for CPT and prolonged exposure were large (Cohen d range, 0.78-1.10). CPT and prolonged exposure also outperformed waitlist and treatment-as-usual control conditions. Forty-nine percent to 70% of participants receiving CPT and prolonged exposure attained clinically meaningful symptom improvement (defined as a 10- to 12-point decrease in interviewer-assessed or self-reported symptoms). However, mean posttreatment scores for CPT and prolonged exposure remained at or above clinical criteria for PTSD, and approximately two-thirds of patients receiving CPT or prolonged exposure retained their PTSD diagnosis after treatment (range, 60%-72%). CPT and prolonged exposure were marginally superior compared with non-trauma-focused psychotherapy comparison conditions. In military and veteran populations, trials of the first-line trauma-focused interventions CPT and prolonged exposure have shown clinically meaningful improvements for many patients with PTSD. However, nonresponse rates have been high, many patients continue to have symptoms, and trauma-focused interventions show marginally superior results compared with active control conditions. There is a need for improvement in existing PTSD treatments and for development and testing of novel evidence-based treatments, both trauma-focused and non-trauma-focused.

The increased adoption of clinical whole exome sequencing (WES) has improved the diagnostic yield for patients with complex genetic conditions. However, the informatics practice for handling information contained in whole exome reports is still in its infancy, as evidenced by the lack of a common vocabulary within clinical sequencing reports generated across genetic laboratories. Genetic testing results are mostly transmitted using portable document format, which can make secondary analysis and data extraction challenging. This paper reviews a sample of clinical exome reports generated by Clinical Laboratory Improvement Amendments-certified genetic testing laboratories at tertiary-care facilities to assess and identify common data elements. Like structured radiology reports, which enable faster information retrieval and reuse, structuring genetic information within clinical WES reports would help facilitate integration of genetic information into electronic health records and enable retrospective research on the clinical utility of WES. We identify elements listed as mandatory according to practice guidelines but are currently missing from some of the clinical reports, which might help to organize the data when stored within structured databases. We also highlight elements, such as patient consent, that, although they do not appear within any of the current reports, may help in interpreting some of the information within the reports. Integrating genetic and clinical information would assist the adoption of personalized medicine for improved patient care and outcomes. © The Author 2017.

Deficiencies in record keeping practices have been reported at primary care level in the public health sector in South Africa. These deficiencies have the potential to negatively impact patient health outcomes as the break in information may hinder continuity of care. This disruption in information management has particular relevance for patients with chronic diseases. The aim of this study was to establish if the implementation of a structured clinical record (SCR) as an adjunct tool to the algorithmic guidelines for chronic disease management improved the quality of clinical records at primary care level. A quasi-experimental study (before and after study with a comparison group) was conducted across 30 primary health care clinics (PHCs) located in three districts in South Africa. Twenty PHCs that received the intervention were selected as intervention clinics and 10 facilities were selected as comparison facilities. The lot quality assurance sampling (LQAS) method was used to determine the number of records required to be reviewed per diagnostic condition per facility. There was a a statistically significant increase in the percentage of clinical records achieving compliance to the minimum criteria from the baseline to six months post-intervention for both HIV patients on antiretroviral treatment and patients with non-communicable diseases (hypertension and diabetes). A multifaceted intervention using a SCR to supplement the educational outreach component (PC 101 training) has demonstrated the potential for improving the quality of clinical records for patients with chronic diseases at primary care clinics in South Africa.

Multimorbidity in heart failure (HF), defined as HF of any aetiology and multiple concurrent conditions that require active management, represents an emerging problem within the ageing HF patient population worldwide. To inform this position paper, we performed: 1) an initial review of the literature identifying the ten most common conditions, other than hypertension and ischaemic heart disease, complicating the management of HF (anaemia, arrhythmias, cognitive dysfunction, depression, diabetes, musculoskeletal disorders, renal dysfunction, respiratory disease, sleep disorders and thyroid disease) and then 2) a review of the published literature describing the association between HF with each of the ten conditions. From these data we describe a clinical framework, comprising five key steps, to potentially improve historically poor health outcomes in this patient population. We identified five key steps (ARISE-HF) that could potentially improve clinical outcomes if applied in a systematic manner: 1) Acknowledge multimorbidity as a clinical syndrome that is associated with poor health outcomes, 2) Routinely profile (using a standardised protocol - adapted to the local health care system) all patients hospitalised with HF to determine the extent of concurrent multimorbidity, 3) Identify individualised priorities and person-centred goals based on the extent and nature of multimorbidity, 4) Support individualised, home-based, multidisciplinary, case management to supplement standard HF management, and 5) Evaluate health outcomes well beyond acute hospitalisation and encompass all-cause events and a person-centred perspective in affected individuals. We propose ARISE-HF as a framework for improving typically poor health outcomes in those affected by multimorbidity in HF. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

2010-01-01

Most patients with mental health (MH) conditions, such as depression, receive care for their conditions from a primary care physician (PCP) in their health/medical home. Providing MH care, however, presents many challenges for the PCP, including (1) the difficulty of getting needed consultation from an MH specialist; (2) the time constraints of a busy PCP practice; (3) the complicated nature of recognizing depression, which may be described with only somatic complaints; (4) the barriers to reimbursement and compensation; and (5) associated medical and social comorbidities. Practice managers, emergency departments, and health plans are stretched to provide care for complex patients with unmet MH needs. At the same time, payment reform linked to accountable care organizations and/or episodic bundle payments, MH parity rules, and increasing MH costs to large employers and payers all highlight the critical need to identify high-quality, efficient, integrated MH care delivery practices. Over the past ten years, Intermountain Healthcare has developed a team-based approach-known as mental health integration (MHI)-for caring for these patients and their families. The team includes the PCPs and their staff, and they, in turn, are integrated with MH professionals, community resources, care management, and the patient and his or her family. The integration model goes far beyond co-location in its team-based approach; it is operationalized at the clinic, thereby improving both physician and staff satisfaction. Patients treated in MHI clinics also show improved satisfaction, lower costs, and better quality outcomes. The MHI program is financially sustainable in routinized clinics without subsidies. MHI is a successful approach to improving care for patients with MH conditions in primary care health homes.

Rhythmic auditory cueing to improve walking in patients with neurological conditions other than Parkinson's disease--what is the evidence?

Wittwer, Joanne E; Webster, Kate E; Hill, Keith

2013-01-01

To investigate whether synchronising over-ground walking to rhythmic auditory cues improves temporal and spatial gait measures in adults with neurological clinical conditions other than Parkinson's disease. A search was performed in June 2011 using the computerised databases AGELINE, AMED, AMI, CINAHL, Current Contents, EMBASE, MEDLINE, PsycINFO and PUBMED, and extended using hand-searching of relevant journals and article reference lists. Methodological quality was independently assessed by two reviewers. A best evidence synthesis was applied to rate levels of evidence. Fourteen studies, four of which were randomized controlled trials (RCTs), met the inclusion criteria. Patient groups included those with stroke (six studies); Huntington's disease and spinal cord injury (two studies each); traumatic brain injury, dementia, multiple sclerosis and normal pressure hydrocephalus (one study each). The best evidence synthesis found moderate evidence of improved velocity and stride length of people with stroke following gait training with rhythmic music. Insufficient evidence was found for other included neurological disorders due to low study numbers and poor methodological quality of some studies. Synchronising walking to rhythmic auditory cues can result in short-term improvement in gait measures of people with stroke. Further high quality studies are needed before recommendations for clinical practice can be made.

To examine current evidence on use of active video gaming (AVG) to improve motor function in children with movement disorders including cerebral palsy, developmental coordination disorder, and Down syndrome. Scopus, MEDLINE, Cochrane Library, EMBASE, and CINAHL were searched. Included papers studied the use of AVG for improving movement-related outcomes in these populations. Parameters studied included health condition, strength of evidence, AVG delivery methods, capacity for individualizing play, outcomes addressed, effectiveness for achieving outcomes, and challenges/limitations. The 20 extracted articles varied in quality. Studies involved children with six different conditions using AVG in clinical, home, or school settings for 49 different motor outcomes. Dosage varied in frequency and duration. Choice of games played and difficulty level were therapist determined (n=6) or child controlled (n=14). The most common study limitations were small sample sizes and difficulty individualizing treatment. All articles showed improvement in outcomes with AVG, although differences were not consistently significant compared with conventional therapy. Heterogeneity of measurement tools and target outcomes prevented meta-analysis or development of formal recommendations. However, AVG is feasible and shows potential for improving outcomes in this population. Additional investigations of dosing variables, utility as a home supplement to clinical care, and outcomes with larger sample sizes are merited. © 2017 Mac Keith Press.

Page, Jonathan M; Harmata, Andrew J; Guelcher, Scott A

2013-12-01

Injectable and settable biomaterials are a growing class of therapeutic technologies within the field of regenerative medicine. These materials offer advantages compared to prefabricated implants because of their ability to be utilized as part of noninvasive surgical procedures, fill complex defect shapes, cure in situ, and incorporate cells and other active biologics. However, there are significant technical barriers to clinical translation of injectable and settable biomaterials, such as achieving clinically relevant handling properties and benign reaction conditions. This review focuses on the engineering challenges associated with the design and development of injectable and chemically settable polymeric biomaterials. Additionally, specific examples of the diverse chemistries utilized to overcome these challenges are covered. The future translation of injectable and settable biomaterials is anticipated to improve patient outcomes for a number of clinical conditions.

Increasing the Capacity of Primary Care Through Enabling Technology.

PubMed

Young, Heather M; Nesbitt, Thomas S

2017-04-01

Primary care is the foundation of effective and high-quality health care. The role of primary care clinicians has expanded to encompass coordination of care across multiple providers and management of more patients with complex conditions. Enabling technology has the potential to expand the capacity for primary care clinicians to provide integrated, accessible care that channels expertise to the patient and brings specialty consultations into the primary care clinic. Furthermore, technology offers opportunities to engage patients in advancing their health through improved communication and enhanced self-management of chronic conditions. This paper describes enabling technologies in four domains (the body, the home, the community, and the primary care clinic) that can support the critical role primary care clinicians play in the health care system. It also identifies challenges to incorporating these technologies into primary care clinics, care processes, and workflow.

Public Reporting of MRI of the Lumbar Spine for Low Back Pain and Changes in Clinical Documentation.

PubMed

Flug, Jonathan A; Lind, Kimberly E

2017-12-01

OP-8 is the Medicare imaging efficiency metric for MRI of the lumbar spine for low back pain in the outpatient hospital. We studied trends in exclusion criteria coding over time by site of service after implementation of OP-8 to evaluate provider's response to public reporting. We conducted a secondary data analysis using the Medicare Limited Data Set 5% sample for beneficiaries with MRI lumbar spine and lower back pain during 2009 to 2014. We evaluated the association between excluding condition prevalence and site by using generalized estimating equations regression. We produced model-based estimates of excluding condition prevalence by site and year. As a sensitivity analysis, we repeated the analysis while including additional conditions in the outcome measure. We included 285,911 MRIs of the lumbar spine for low back pain. Generalized estimating equations regression found that outpatient hospitals had a higher proportion of MRIs with at least one excluding condition documented compared with outpatient clinics (P < .05), but increases in excluding condition prevalence were similar across all sites during 2009 to 2014. Our results were not sensitive to the inclusion of additional conditions. Documentation of excluding conditions and other clinically reasonable exclusions for OP-8 increased over time for outpatient hospitals and clinics. Increases in documentation of comorbidities may not translate to actual improvement in imaging appropriateness for low back pain. When accounting for all relevant conditions, the proportion of patients with low back pain considered uncomplicated and being measured by OP-8 would be small, reflecting a small proportion of patients with low back pain.

Private prayer associations with depression, anxiety and other health conditions: an analytical review of clinical studies.

PubMed

Anderson, James W; Nunnelley, Paige A

2016-09-01

To critically analyze appropriate clinical studies to assess the relationship between health conditions and the frequency of private prayer. Private prayer is defined as individuals praying for themselves. Using PubMed and other search engines, we identified over 300 articles reporting relationships between prayer and health conditions. We identified 41 observational clinical studies that evaluated the relationship between private prayer and health conditions. Prayer scores of 5 to 1 were assigned to studies, with 5 being private prayer for health and 1 being prayer in combination with meditation or Bible study. Frequency scores ranged from 3 to 1 with 3 being twice daily or more and 0 when frequency was not assessed. Studies were ranked from 8 to 1 based on the sum of Prayer and Frequency Scores. Twenty-one studies had Prayer-Frequency scores of 5 to 8, indicating that they evaluated private prayer (praying for one's own health) of suitable frequency in association with health conditions. Nine of 11 studies indicated that private prayer was associated with a significantly lower prevalence of depression (P value, <0.01). Optimism as well as coping were significantly improved by prayer in four studies (P value, P < 0.01). In 10 studies of mental health conditions-including anxiety and confusion-there was a significant benefit associated with prayer (P < 0.01), In the reviewed studies, prayer did not have a significant effect on physical health or blood pressure. The reported observational studies suggest that frequent private prayer is associated with a significant benefit for depression, optimism, coping, and other mental health conditions such as anxiety. Controlled clinical trials are required to critically assess the associations of private prayer and health conditions.

Accurate prognosis is an essential aspect of good clinical practice and efficient health services, particularly for chronic and disabling diseases, as in geriatric populations. This study aims to examine the accuracy of clinical prognostic predictions and to devise prediction models combining clinical variables and clinicians' prognosis for a geriatric patient sample. In a sample of 329 consecutive older patients admitted to 10 geriatric units, we evaluated the accuracy of clinicians' prognosis regarding three outcomes at discharge: global functioning, length of stay (LoS) in hospital, and destination at discharge (DD). A comprehensive set of sociodemographic, clinical, and treatment-related information were also collected. Moderate predictive performance was found for all three outcomes: area under receiver operating characteristic curve of 0.79 and 0.78 for functioning and LoS, respectively, and moderate concordance, Cohen's K = 0.45, between predicted and observed DD. Predictive models found the Blaylock Risk Assessment Screening Score together with clinicians' judgment relevant to improve predictions for all outcomes (absolute improvement in adjusted and pseudo-R(2) up to 19%). Although the clinicians' estimates were important factors in predicting global functioning, LoS, and DD, more research is needed regarding both methodological aspects and clinical measurements, to improve prognostic clinical indices.

Clinical decision support systems (CDSS) integrated within Electronic Medical Records (EMR) hold the promise of improving healthcare quality. To date the effectiveness of CDSS has been less than expected, especially concerning the ambulatory management of chronic diseases. This is due, in part, to the fact that clinicians do not use CDSS fully. Barriers to clinicians' use of CDSS have included lack of integration into workflow, software usability issues, and relevance of the content to the patient at hand. At Partners HealthCare, we are developing “Smart Forms” to facilitate documentation-based clinical decision support.

Clinical decision support systems (CDSS) integrated within Electronic Medical Records (EMR) hold the promise of improving healthcare quality. To date the effectiveness of CDSS has been less than expected, especially concerning the ambulatory management of chronic diseases. This is due, in part, to the fact that clinicians do not use CDSS fully. Barriers to clinicians' use of CDSS have included lack of integration into workflow, software usability issues, and relevance of the content to the patient at hand. At Partners HealthCare, we are developing "Smart Forms" to facilitate documentation-based clinical decision support. Rather than being interruptive in nature, the Smart Form enables writing a multi-problem visit note while capturing coded information and providing sophisticated decision support in the form of tailored recommendations for care. The current version of the Smart Form is designed around two chronic diseases: coronary artery disease and diabetes mellitus. The Smart Form has potential to improve the care of patients with both acute and chronic conditions.

With non-communicable conditions accounting for nearly two-thirds of deaths worldwide, the emergence of chronic diseases as the predominant challenge to global health is undisputed. In the USA, chronic diseases are the main causes of poor health, disability, and death, and account for most of health-care expenditures. The chronic disease burden in the USA largely results from a short list of risk factors--including tobacco use, poor diet and physical inactivity (both strongly associated with obesity), excessive alcohol consumption, uncontrolled high blood pressure, and hyperlipidaemia--that can be effectively addressed for individuals and populations. Increases in the burden of chronic diseases are attributable to incidence and prevalence of leading chronic conditions and risk factors (which occur individually and in combination), and population demographics, including ageing and health disparities. To effectively and equitably address the chronic disease burden, public health and health-care systems need to deploy integrated approaches that bundle strategies and interventions, address many risk factors and conditions simultaneously, create population-wide changes, help the population subgroups most affected, and rely on implementation by many sectors, including public-private partnerships and involvement from all stakeholders. To help to meet the chronic disease burden, the US Centers for Disease Control and Prevention (CDC) uses four cross-cutting strategies: (1) epidemiology and surveillance to monitor trends and inform programmes; (2) environmental approaches that promote health and support healthy behaviours; (3) health system interventions to improve the effective use of clinical and other preventive services; and (4) community resources linked to clinical services that sustain improved management of chronic conditions. Establishment of community conditions to support healthy behaviours and promote effective management of chronic conditions will deliver healthier students to schools, healthier workers to employers and businesses, and a healthier population to the health-care system. Collectively, these four strategies will prevent the occurrence of chronic diseases, foster early detection and slow disease progression in people with chronic conditions, reduce complications, support an improved quality of life, and reduce demand on the health-care system. Of crucial importance, with strengthened collaboration between the public health and health-care sectors, the health-care system better uses prevention and early detection services, and population health is improved and sustained by solidifying collaborations between communities and health-care providers. This collaborative approach will improve health equity by building communities that promote health rather than disease, have more accessible and direct care, and focus the health-care system on improving population health.

Musculoskeletal pain in the workforce: the effects of back, arthritis, and fibromyalgia pain on quality of life and work productivity.

PubMed

McDonald, Margaret; DiBonaventura, Marco daCosta; Ullman, Stacey

2011-07-01

To investigate the impact of musculoskeletal pain on health-related quality of life and work productivity losses among US workers. Data from the 2008 US National Health and Wellness Survey were used. Among those currently employed aged 20 to 64 years (N = 30,868), workers with arthritis (n = 2,670), back (n = 4,920), and fibromyalgia (n = 439) pain were compared with workers without those respective musculoskeletal pain conditions. Arthritis, back, and fibromyalgia pain were all associated with significantly lower levels of health-related quality of life, often at clinically meaningful levels. All pain conditions were associated with higher levels of work productivity loss, even after adjusting for demographic and health characteristics. Musculoskeletal pain conditions were highly prevalent and associated with a significant burden. Improved management of these conditions may lead to improved productivity, benefiting both employers and workers alike.

The Effects of Digital Noise Reduction on the Acceptance of Background Noise

Mueller, H. Gustav; Weber, Jennifer; Hornsby, Benjamin W. Y.

2006-01-01

Modern hearing aids commonly employ digital noise reduction (DNR) algorithms. The potential benefit of these algorithms is to provide improved speech understanding in noise or, at the least, to provide relaxed listening or increased ease of listening. In this study, 22 adults were fitted with 16-channel wide-dynamic-range compression hearing aids containing DNR processing. The DNR includes both modulation-based and Wiener-filter-type algorithms working simultaneously. Both speech intelligibility and acceptable noise level (ANL) were assessed using the Hearing in Noise Test (HINT) with DNR on and DNR off. The ANL was also assessed without hearing aids. The results showed a significant mean improvement for the ANL (4.2 dB) for the DNR-on condition when compared to DNR-off condition. Moreover, there was a significant correlation between the magnitude of ANL improvement (relative to DNR on) and the DNR-off ANL. There was no significant mean improvement for the HINT for the DNR-on condition, and on an individual basis, the HINT score did not significantly correlate with either aided ANL (DNR on or DNR off). These findings suggest that at least within the constraints of the DNR algorithms and test conditions employed in this study, DNR can significantly improve the clinically measured ANL, which may result in improved ease of listening for speech-in-noise situations.

2016-01-01

The role of light-based technologies in dermatology has expanded dramatically in recent years. Lasers and intense pulsed light have been used to safely and effectively treat a diverse array of cutaneous conditions, including vascular and pigmented lesions, tattoos, scars, and undesired hair, while also providing extensive therapeutic options for cosmetic rejuvenation and other dermatologic conditions. Dermatologic laser procedures are becoming increasingly popular worldwide, and demand for them has fueled new innovations and clinical applications. These systems continue to evolve and provide enhanced therapeutic outcomes with improved safety profiles. This review highlights the important roles and varied clinical applications that lasers and intense pulsed light play in the dermatologic practice. PMID:26893574

Chronic Achilles Tendon Disorders: Tendinopathy and Chronic Rupture.

PubMed

Maffulli, Nicola; Via, Alessio Giai; Oliva, Francesco

2015-10-01

Tendinopathy of the Achilles tendon involves clinical conditions in and around the tendon and it is the result of a failure of a chronic healing response. Although several conservative therapeutic options have been proposed, few of them are supported by randomized controlled trials. The management is primarily conservative and many patients respond well to conservative measures. If clinical conditions do not improve after 6 months of conservative management, surgery is recommended. The management of chronic ruptures is different from that of acute ruptures. The optimal surgical procedure is still debated. In this article chronic Achilles tendon disorders are debated and evidence-based medicine treatment strategies are discussed.

2018-06-19

Clinical pharmacists provide beneficial services to adult patients, though their benefits for paediatric hospital patients are less defined. Five databases were searched using the MeSH terms 'clinical pharmacist', 'paediatric/paediatric', 'hospital', and 'intervention' for studies with paediatric patients conducted in hospital settings, and described pharmacist-initiated interventions, published between January 2000 and October 2017. The search strategy after full-text review identified 12 articles matching the eligibility criteria. Quality appraisal checklists from the Joanna Briggs Institute were used to appraise the eligible articles. Clinical pharmacist services had a positive impact on paediatric patient care. Medication errors intercepted by pharmacists included over- and under-dosing, missed doses, medication history gaps, allergies, and near-misses. Interventions to address these errors were positively received, and implemented by physicians, with an average acceptance rate of over 95%. Clinical pharmacist-initiated education resulted in improved medication understanding and adherence, improved patient satisfaction, and control of chronic medical conditions. This review found that clinical pharmacists in paediatric wards may reduce drug-related problems and improve patient outcomes. The benefits of pharmacist involvement appear greatest when directly involved in ward rounds, due to being able to more rapidly identify medication errors during the prescribing phase, and provide real-time advice and recommendations to prescribers. What is Known: • Complex paediatric conditions can require multiple pharmaceutical treatments, utilised in a safe manner to ensure good patient outcomes • The benefits of pharmacist interventions when using these treatments are well-documented in adult patients, though less so in paediatric patients What is New: • Pharmacists are adept at identifying and managing medication errors for paediatric patients, including incorrect doses, missed doses, and gaps in medication history • Interventions recommended by pharmacists are generally well-accepted by prescribing physicians, especially when recommendations can be made during the prescribing phase of treatment.

Auckland District Health Board was one of four District Health Boards to trial the Breakthrough Series (BTS) methodology to improve the management of long-term conditions in New Zealand, with support from the Ministry of Health. To improve clinical outcomes, facilitate planned care and promote quality improvement within participating practices in Auckland. Implementation of the Collaborative followed the improvement model / Institute for Healthcare Improvement methodology. Three topic areas were selected: system redesign, cardio-vascular disease/diabetes, and self-management support. An expert advisory group and the Improvement Foundation Australia helped guide project development and implementation. Primary Health Organisation facilitators were trained in the methodology and 15 practice teams participated in the three learning workshops and action periods over 12 months. An independent evaluation study using both quantitative and qualitative methods was conducted. Improvements were recorded in cardiovascular disease risk assessment, practice-level systems of care, self-management systems and follow-up and coordination for patients. Qualitative research found improvements in coordination and teamwork, knowledge of practice populations and understanding of managing long-term conditions. The Collaborative process delivered some real improvements in the systems of care for people with long-term conditions and a change in culture among participating practices. The findings suggest that by strengthening facilitation processes, improving access to comprehensive population audit tools and lengthening the time frame, the process has the potential to make significant improvements in practice. Other organisations should consider this approach when investigating quality improvement programmes.

ABSTRACT Objectives: cross-culturally adapt to the Spanish context and make a new proposal for the nursing outcome, Physical Condition (2004), of the Nursing Outcomes Classification (NOC) for its precise use in clinical practice. Method: a cross-cultural adaptation study and a proposal for the nursing outcome, Physical Condition, was conducted and supported by the opinion of 26 experts. The data was obtained through an electronic form, and a quantitative analysis was conducted, using the SPSS software. Results: the version adapted to the Spanish context was obtained and the proposal of the outcome, Physical Condition, received agreement from 26 experts, with a mean score greater than 7.6 for adequacy of the outcome definition and its indicators, and 8.5 for the relevance of the indicators. Conclusions: the version adapted to the Spanish context and a new proposal for Physical Condition were obtained. The results obtained indicate a high level of adequacy and relevance, an instrument of great utility in the clinic, and research was obtained to evaluate the interventions directed to the improvement of the physical condition.

Hypersomnia and depressive symptoms: methodological and clinical aspects

PubMed Central

2013-01-01

The associations between depressive symptoms and hypersomnia are complex and often bidirectional. Of the many disorders associated with excessive sleepiness in the general population, the most frequent are mental health disorders, particularly depression. However, most mood disorder studies addressing hypersomnia have assessed daytime sleepiness using a single response, neglecting critical and clinically relevant information about symptom severity, duration and nighttime sleep quality. Only a few studies have used objective tools such as polysomnography to directly measure both daytime and nighttime sleep propensity in depression with normal mean sleep latency and sleep duration. Hypersomnia in mood disorders, rather than a medical condition per se, is more a subjective sleep complaint than an objective finding. Mood symptoms have also been frequently reported in hypersomnia disorders of central origin, especially in narcolepsy. Hypocretin deficiency could be a contributing factor in this condition. Further interventional studies are needed to explore whether management of sleep complaints improves mood symptoms in hypersomnia disorders and, conversely, whether management of mood complaints improves sleep symptoms in mood disorders.

Clinical trials of various procedures, including bone marrow stimulation, mosaicplasty, and autologous chondrocyte implantation, have been explored to treat articular cartilage defects. However, all of them have some demerits. We focused on autologous culture-expanded bone marrow mesenchymal stem cells (BMSC), which can proliferate without losing their capacity for differentiation. First, we transplanted BMSC into the defective articular cartilage of rabbit and succeeded in regenerating osteochondral tissue. We then applied this transplantation in humans. Our previous reports showed that treatment with BMSC relieves the clinical symptoms of chondral defects in the knee and elbow joint. We investigated the efficacy of BMSC for osteoarthritic knee treated with high tibial osteotomy, by comparing 12 BMSC-transplanted patients with 12 cell-free patients. At 16-month follow-up, although the difference in clinical improvement between both groups was not significant, the arthroscopic and histological grading score was better in the cell-transplanted group. At the over 10-year follow-up, Hospital for Special Surgery knee scores improved to 76 and 73 in the BMSC-transplanted and cell-free groups, respectively, which were better than preoperative scores. Additionally, neither tumors nor infections were observed in all patients, and in the clinical study, we have never observed hypertrophy of repaired tissue, thereby guaranteeing the clinical safety of this therapy. Although we have never observed calcification above the tidemark in rabbit model and human histologically, the repair cartilage was not completely hyaline cartilage. To elucidate the optimum conditions for cell therapy, other stem cells, culture conditions, growth factors, and gene transfection methods should be explored.

A web-based simulation of a longitudinal clinic used in a 4-week ambulatory rotation: a cohort study

Wong, Rene WG; Lochnan, Heather A

2009-01-01

Background Residency training takes place primarily on inpatient wards. In the absence of a resident continuity clinic, internal medicine residents rely on block rotations to learn about continuity of care. Alternate methods to introduce continuity of care are needed. Methods A web-based tool, Continuity of Care Online Simulations (COCOS), was designed for use in a one-month, postgraduate clinical rotation in endocrinology. It is an interactive tool that simulates the continuing care of any patient with a chronic endocrine disease. Twenty-three residents in internal medicine participated in a study to investigate the effects of using COCOS during a clinical rotation in endocrinology on pre-post knowledge test scores and self-assessment of confidence. Results Compared to residents who did the rotation alone, residents who used COCOS during the rotation had significantly higher improvements in test scores (% increase in pre-post test scores +21.6 [standard deviation, SD, 8.0] vs. +5.9 [SD 6.8]; p < .001). Test score improvements were most pronounced for less commonly seen conditions. There were no significant differences in changes in confidence. Residents rated COCOS very highly, recommending its use as a standard part of the rotation and throughout residency. Conclusion A stand-alone web-based tool can be incorporated into an existing clinical rotation to help residents learn about continuity of care. It has the most potential to teach residents about topics that are less commonly seen during a clinical rotation. The adaptable, web-based format allows the creation of cases for most chronic medical conditions. PMID:19187554

2017-01-01

Premature ejaculation remains a difficult condition to manage for patients, their partners, and the clinician. Whilst prevalence rates are estimated to be 20–40%, determining a diagnosis of premature ejaculation is difficult, as the definition remains both subjective and ill-defined in the clinical context. As our understanding of the ejaculatory pathway has improved, new opportunities to treat the condition have evolved with mixed results. In this review, we explore some of these controversies surrounding the aetiology, diagnosis, and treatment of this condition and discuss potential novel therapeutic options. PMID:29259775

Berg, Gregory D; Leary, Fredric; Medina, Wendie; Donnelly, Shawn; Warnick, Kathleen

2015-02-01

The objective was to estimate clinical metric and medication persistency impacts of a care management program. The data sources were Medicaid administrative claims for a sample population of 32,334 noninstitutionalized Medicaid-only aged, blind, or disabled patients with diagnosed conditions of asthma, coronary artery disease, chronic obstructive pulmonary disease, diabetes, or heart failure between 2005 and 2009. Multivariate regression analysis was used to test the hypothesis that exposure to a care management intervention increased the likelihood of having the appropriate medication or procedures performed, as well as increased medication persistency. Statistically significant clinical metric improvements occurred in each of the 5 conditions studied. Increased medication persistency was found for beta-blocker medication for members with coronary artery disease, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and diuretic medications for members with heart failure, bronchodilator and corticosteroid medications for members with chronic obstructive pulmonary disease, and aspirin/antiplatelet medications for members with diabetes. This study demonstrates that a care management program increases the likelihood of having an appropriate medication dispensed and/or an appropriate clinical test performed, as well as increased likelihood of medication persistency, in people with chronic conditions.

Missed evidence-based monitoring in high-risk conditions (e.g., cancer) leads to delayed diagnosis. Current technological solutions fail to close this safety gap. In response, we aim to demonstrate a novel method to identify common vulnerabilities across clinics and generate attributes for context-flexible population-level monitoring solutions for widespread implementation to improve quality. Based on interviews with staff in otolaryngology, pulmonary, urology, breast, and gastroenterology clinics at a large urban publicly funded health system, we applied journey mapping to co-develop a visual representation of how patients are monitored for high-risk conditions. Using a National Academies framework and context-sensitivity theory, we identified common systems vulnerabilities and developed preliminary concepts for improving the robustness for monitoring patients with high-risk conditions ("design seeds" for potential solutions). Finally, we conducted a face validity and prioritization assessment of the design seeds with the original interviewees. We identified five high-risk situations for potentially consequential diagnostic delays arising from suboptimal patient monitoring. All situations related to detection of cancer (head and neck, lung, prostate, breast, and colorectal). With clinic participants we created 5 journey maps, each representing specialty clinic workflow directed at evidence-based monitoring. System vulnerabilities common to the different clinics included challenges with: data systems, communications handoffs, population-level tracking, and patient activities. Clinic staff ranked 13 design seeds (e.g., keep patient list up to date, use triggered notifications) addressing these vulnerabilities. Each design seed has unique evaluation criteria for the usefulness of potential solutions developed from the seed. We identified and ranked 13 design seeds that characterize situations that clinicians described 'wake them up at night', and thus could reduce their anxiety, save time, and improve monitoring of high-risk patients. We anticipate that the design seed approach promotes robust and context-sensitive solutions to safety and quality problems because it provides a human-centered link between the experienced problem and various solutions that can be tested for viability. The study also demonstrates a novel integration of industrial and human factors methods (journey mapping, process tracing and design seeds) linked to implementation theory for use in designing interventions that anticipate and reduce implementation challenges.

The specimen management system with barcode needs to be improved in order to solve inherent problems in work performance. This study describes the application of Radio Frequency Identification (RFID) which is the solution for the problems associated with specimen labeling and management. A new specimen management system and architecture with RFID technology for clinical laboratory was designed. The suggested system was tested in various conditions such as durability to temperature and aspect of effective utilization of new work flow under a virtual hospital clinical laboratory environment. This system demonstrates its potential application in clinical laboratories for improving work flow and specimen management. The suggested specimen management system with RFID technology has advantages in comparison to the traditional specimen management system with barcode in the aspect of mass specimen processing, robust durability of temperature, humidity changes, and effective specimen tracking.

Summary China faces the immediate need of addressing the rapidly growing population with cardiovascular disease (CVD) events and the increasing numbers who are living with CVD. Despite progress in increasing access to services, China faces the dual challenge of addressing gaps in quality of care and producing more evidence to support clinical practice. In this article, we address opportunities to strengthen performance measurement, programs to improve quality of care and national capacity to produce high impact knowledge for clinical practice. Moreover, we propose recommendations, with implications for other conditions, for how China can immediately leverage its Hospital Quality Monitoring System and other existing national platforms to evaluate and improve performance, as well as generate new knowledge to inform clinical decisions and national policies.

The Effectiveness of Self-Management Mobile Phone and Tablet Apps in Long-term Condition Management: A Systematic Review

PubMed Central

2016-01-01

Background Long-term conditions and their concomitant management place considerable pressure on patients, communities, and health care systems worldwide. International clinical guidelines on the majority of long-term conditions recommend the inclusion of self-management programs in routine management. Self-management programs have been associated with improved health outcomes; however, the successful and sustainable transfer of research programs into clinical practice has been inconsistent. Recent developments in mobile technology, such as mobile phone and tablet computer apps, could help in developing a platform for the delivery of self-management interventions that are adaptable, of low cost, and easily accessible. Objective We conducted a systematic review to assess the effectiveness of mobile phone and tablet apps in self-management of key symptoms of long-term conditions. Methods We searched PubMed, Embase, EBSCO databases, the Cochrane Library, and The Joanna Briggs Institute Library for randomized controlled trials that assessed the effectiveness of mobile phone and tablet apps in self-management of diabetes mellitus, cardiovascular disease, and chronic lung diseases from 2005–2016. We searched registers of current and ongoing trials, as well as the gray literature. We then checked the reference lists of all primary studies and review papers for additional references. The last search was run in February 2016. Results Of the 9 papers we reviewed, 6 of the interventions demonstrated a statistically significant improvement in the primary measure of clinical outcome. Where the intervention comprised an app only, 3 studies demonstrated a statistically significant improvement. Interventions to address diabetes mellitus (5/9) were the most common, followed by chronic lung disease (3/9) and cardiovascular disease (1/9). A total of 3 studies included multiple intervention groups using permutations of an intervention involving an app. The duration of the intervention ranged from 6 weeks to 1 year, and final follow-up data ranged from 3 months to 1 year. Sample size ranged from 48 to 288 participants. Conclusions The evidence indicates the potential of apps in improving symptom management through self-management interventions. The use of apps in mHealth has the potential to improve health outcomes among those living with chronic diseases through enhanced symptom control. Further innovation, optimization, and rigorous research around the potential of apps in mHealth technology will move the field toward the reality of improved health care delivery and outcomes.

The present study assessed the activity of a combination of dinotefuran and pyriproxyfen (Vectra® Felis) for long-term control (3 months) of allergic dermatitis (AD) in privately-owned cats under common household conditions in Ile-de-France region. This was an open pre-treatment vs post-treatment study. Twenty-eight client-owned cats with clinical signs of AD were enrolled in the study. They received topical application of the combination of dinotefuran and pyriproxyfen on days 0, 28, 56 and 84. Two parameters (clinical signs and pruritus severity) were used to assess the animals' condition on days 0, 28 and 84. Fleas were counted if they were observed. Of the 28 cats initially enrolled, 26 were presented on day 28 and 20 for the final evaluation on day 84. A significant improvement in clinical signs and pruritus was observed in cats for which fleas and/or flea feces were detected on day 0. Globally, the post-treatment AD clinical scores on days 28 and 84 were different from that of the pre-treatment on day 0, with a reduction of 30% and 71%, respectively. For cats with fleas and/or flea feces, the reduction on days 28 and 84 was 33% and 85%, respectively. The improvement of clinical signs and pruritus was not significant in cats with no visible fleas and no flea feces at the beginning of the trial (n = 8). The present study indicated that the treatment with a combination of dinotefuran and pyriproxyfen should be considered as useful in controlling fleas on cats without additional environmental treatment and useful for long-term control of clinical signs and pruritus in allergic cats.

Distinct management issues with Crohn's disease of the small intestine.

PubMed

Fong, Steven C M; Irving, Peter M

2015-03-01

Small bowel Crohn's disease can present with clinical challenges that are specific to its location. In this review, we address some of the areas that present particular problems in small bowel Crohn's disease. A key issue specific to small bowel Crohn's disease relates to its diagnosis given that access to the small bowel is limited. Radiological advances, particularly in small bowel ultrasonography and MRI, as well as the introduction of capsule endoscopy and balloon enteroscopy are helping to address this. In addition, our ability to differentiate small bowel Crohn's disease from other causes of inflammation, such as tuberculosis, is improving on the basis of better understanding of the features that differentiate these conditions. It is also becoming apparent that jejunal Crohn's disease represents a distinct disease phenotype with potentially worse clinical outcomes. Finally, because it is a rare complication, our understanding of small bowel cancer associated with Crohn's disease remains limited. Recent publications are, however, starting to improve our knowledge of this condition. Although small bowel Crohn's disease presents specific management issues not seen in patients with Crohn's disease elsewhere in the gastrointestinal tract, our knowledge of how to manage these is improving.

Has patient survival following renal transplantation improved in the era of modern immunosuppression?

PubMed

Hernández, Domingo; Moreso, Francesc

2013-01-01

Renal transplantation (TX) is the treatment of choice in the majority of patients with chronic kidney disease. But, these patients have a high mortality rate with respect to the general population despite new immunosuppression treatments and improved clinical management. This justifies that the excellent results obtained in the short terms do not have a parallel clinical benefit in the long term. This worrying situation is probably due to a high prevalence of cardiovascular conditions and infectious and neoplastic entities amongst this population against a backdrop of immunosuppression treatment. Furthermore, there is interaction between these processes, which share causal factors and common pathogenic mechanisms. Mortality thus increases. Therefore, identifying the causes of death and the risk factors, applying morbidity and mortality predictive models and intervening in causal factors could constitute some of the strategies for improving renal transplantation results in terms of survival. This review analyses some of the evidence conditioning this high mortality rate following TX, as well and the therapeutic and prognostic aspects associated with co-morbidity: 1) Magnitude of the problem and causes of death among sufferers; 2) Identification of mortality risk factors; 3) Therapeutic strategies for decrease post-TX mortality and; 4) Prediction of mortality and ischaemic heart disease.

To evaluate the comparability and responsiveness of Patient-Reported Outcomes Measurement Information System (PROMIS) fatigue item bank across six chronic conditions. Individuals (n = 1,430) with chronic obstructive pulmonary disease (n = 125), chronic heart failure (n = 60), chronic back pain (n = 218), major depressive disorder (n = 196), rheumatoid arthritis (n = 521), and cancer (n = 310) completed assessments from the PROMIS fatigue item bank at baseline and a clinically relevant follow-up. The cancer and arthritis samples were followed in observational studies; the other four groups were enrolled immediately before a planned clinical intervention. All participants completed global ratings of change at follow-up. Linear mixed-effects models and standardized response means were estimated to examine clinical validity and responsiveness to change. All patient groups reported more fatigue than the general population (range = 0.2-1.29 standard deviation worse). The four clinical groups with pretreatment baseline data experienced significant improvement in fatigue at follow-up (effect size range = 0.25-0.91). Individuals reporting better overall health usually experienced larger fatigue changes than those reporting worse overall health. The results support the PROMIS fatigue measures's responsiveness to change in six different chronic conditions. In addition, these results support the ability of the PROMIS fatigue measures to compare differences in fatigue across a range of chronic conditions, thereby enabling comparative effectiveness research.

Background To reduce the cost of health care while increasing efficiency and quality, health systems are seeking innovative means to engage and empower patients. Improved use of information technology and electronic health record (EHR) infrastructure is essential, and required for “meaningful use” as mandated by the federal government. Providing personalized health information using tablets at the point of care could enhance the clinical experience and enable efficient collection of patient reported outcome measures to guide clinical decision making. Objective The aim of this study is to explore patient and provider attitudes and interest in a proposed clinic-based tablet system for personal health information exchange. To provide a context to understand patients’ use of tablets during their clinic visit, we also examine patients’ current activities and time spent in the waiting room, and their use of health information resources. Methods Surveys were administered to 84 patients in the waiting room of a community health center affiliated with Massachusetts General Hospital (MGH) in Boston, MA. This survey included a vignette and illustration describing a proposed tablet-based system in which the patient, upon sign in at the clinic, receives a tablet loaded with personalized information tailored to their specific medical conditions and preferences. Patients were queried about their interest in such a system in comparison to traditional forms of patient education as well as their current health information seeking behaviors and activities and time spent in the waiting room. Interviews with five MGH-affiliated health care providers were conducted to assess their opinions regarding the proposed tablet system. Results The majority (>60%) of patients were “very” or “extremely” interested in the proposed tablet system and thought it would improve their knowledge about their medical condition (60%), assist them in making healthy choices (57%), and help them to feel more comfortable talking with their provider (55%). Patients thought the system would be more motivating, informative, and engaging than traditional printed health education materials. The tablet system was not considered more effective than face-to-face interaction with providers, though 44% thought it would improve their relationship with their physician. Overall, 91% of respondents were willing to learn how to use a tablet and 75% reported being “very” or “extremely” confident they could use one. Four of the five providers believed that the proposed tablet system would improve clinical workflow and patient education. Patients and providers were concerned about privacy and security of data collected using the tablets. Conclusions Both patients and providers were highly amenable to integrating tablets into the clinical experience, and tablets may be useful in improving patients’ health knowledge, the collection of patient reported outcome measures, and improved patient-provider communication. Further research into operationalizing such systems and their validation is necessary before integration into standard clinical practice. PMID:26481906

OBJECTIVE: This study examines the relationships among organizational culture, quality improvement processes and selected outcomes for a sample of up to 61 U. S. hospitals. DATA SOURCES AND STUDY SETTING: Primary data were collected from 61 U. S. hospitals (located primarily in the midwest and the west) on measures related to continuous quality improvement/total quality management (CQI/TQM), organizational culture, implementation approaches, and degree of quality improvement implementation based on the Baldrige Award criteria. These data were combined with independently collected data on perceived impact and objective measures of clinical efficiency (i.e., charges and length of stay) for six clinical conditions. STUDY DESIGN: The study involved cross-sectional examination of the named relationships. DATA COLLECTION/EXTRACTION METHODS: Reliable and valid scales for the organizational culture and quality improvement implementation measures were developed based on responses from over 7,000 individuals across the 61 hospitals with an overall completion rate of 72 percent. Independent data on perceived impact were collected from a national survey and independent data on clinical efficiency from a companion study of managed care. PRINCIPAL FINDINGS: A participative, flexible, risk-taking organizational culture was significantly related to quality improvement implementation. Quality improvement implementation, in turn, was positively associated with greater perceived patient outcomes and human resource development. Larger-size hospitals experienced lower clinical efficiency with regard to higher charges and higher length of stay, due in part to having more bureaucratic and hierarchical cultures that serve as a barrier to quality improvement implementation. CONCLUSIONS: What really matters is whether or not a hospital has a culture that supports quality improvement work and an approach that encourages flexible implementation. Larger-size hospitals face more difficult challenges in this regard. PMID:7782222

Physicians ask many complex questions during the patient encounter. Information retrieval systems that can provide immediate and relevant answers to these questions can be invaluable aids to the practice of evidence-based medicine. In this study, we first automatically identify topic keywords from ad hoc clinical questions with a Condition Random Field model that is trained over thousands of manually annotated clinical questions. We then report on a linear model that assigns query weights based on their automatically identified semantic roles: topic keywords, domain specific terms, and their synonyms. Our evaluation shows that this weighted keyword model improves information retrieval from the Text Retrieval Conference Genomics track data. PMID:21347188

Intestinal mucosal atrophy and adaptation

PubMed Central

Shaw, Darcy; Gohil, Kartik; Basson, Marc D

2012-01-01

Mucosal adaptation is an essential process in gut homeostasis. The intestinal mucosa adapts to a range of pathological conditions including starvation, short-gut syndrome, obesity, and bariatric surgery. Broadly, these adaptive functions can be grouped into proliferation and differentiation. These are influenced by diverse interactions with hormonal, immune, dietary, nervous, and mechanical stimuli. It seems likely that clinical outcomes can be improved by manipulating the physiology of adaptation. This review will summarize current understanding of the basic science surrounding adaptation, delineate the wide range of potential targets for therapeutic intervention, and discuss how these might be incorporated into an overall treatment plan. Deeper insight into the physiologic basis of adaptation will identify further targets for intervention to improve clinical outcomes. PMID:23197881

The drug-induced degradation of oncoproteins: an unexpected Achilles' heel of cancer cells?

PubMed

Ablain, Julien; Nasr, Rihab; Bazarbachi, Ali; de Thé, Hugues

2011-07-01

Many targeted therapies against cancer are aimed at inhibiting the enzymatic activity of kinases. Thus far, this approach has undoubtedly yielded significant clinical improvements, but has only rarely achieved cures. Other drugs, which selectively elicit proteasome-dependent degradation of oncoproteins, induce the loss of cancer cell self-renewal and promote cell differentiation and/or apoptosis. In acute promyelocytic leukemia, the cooperative degradation of PML/RARA by arsenic and retinoic acid cures most patients. In this condition and others, drug-induced proteolysis of oncoproteins is feasible and underlies improved clinical outcome. Several transcription factors, nuclear receptors, or fusion proteins driving cancer growth could be candidates for proteolysis-based drug-discovery programs.

We prospectively studied 26 patients with ischemic stroke within 24 hr, after 2 wk, and after 6 mo with thallium-201-diethyldithiocarbamate single-photon emission computed tomography (SPECT) and neurologic and functional assessments. The admission flow deficits correlated with outcome. The admission and 6-mo scores correlated with clinical conditions at each time. At 2 wk, the flow deficits were smaller and did not correlate with clinical parameters. Nor did the presence or absence of hyperfixation of the radiopharmaceutical. Six months after the infarct, the flow defect had decreased in 9 of 15 patients in whom three serial scans were available, with better clinicalmore » improvement than in the remaining six whose flow deficits increased. More patients in the first group had been treated randomly with the calcium-entry blocker flunarizine. SPECT imaging of rCBF within 24 hr after stroke correlates with clinical outcome and condition, whereas rCBF imaging at 2 wk after the stroke shows no clinical correlation.« less

Older age is associated with an increased accumulation of multiple chronic conditions. The clinical management of patients suffering from multiple chronic conditions is very complex, disconnected and time-consuming with the traditional care settings. Integrated care is a means to address the growing demand for improved patient experience and health outcomes of multimorbid and long-term care patients. Care planning is a prevalent approach of integrated care, where the aim is to deliver more personalized and targeted care creating shared care plans by clearly articulating the role of each provider and patient in the care process. In this paper, we present a method and corresponding implementation of a semi-automatic care plan management tool, integrated with clinical decision support services which can seamlessly access and assess the electronic health records (EHRs) of the patient in comparison with evidence based clinical guidelines to suggest personalized recommendations for goals and interventions to be added to the individualized care plans.

Shared decision-making approach to uncertain clinical situations such as cancer screening seems more appropriate than ever. Shared decision making can be defined as an interactive process where physician and patient share all the stages of the decision making process. For patients who wish to be implicated in the management of their health conditions, physicians might express difficulty to do so. Use of patient decision aids appears to improve such process of shared decision making.

Malassezia species, organisms normally colonizing the skin surface, are thought to play a role as either the cause or an exacerbating factor in a number of skin conditions, including pityriasis versicolor, Malassezia folliculitis, seborrheic dermatitis (SD) and atopic dermatitis (AD). Using a non-cultural PCR method, we analyzed Malassezia spp. extracted from the skin surface of SD and AD patients. The species most commonly detected in both patient groups were M. globosa and M. restricta, and the number of Malassezia spp. In these patients was higher than in healthy subjects. After a topical application of 2% ketoconazole cream, changes in the population of Malassezia spp. in 20 intractable cases of AD were recorded. The addition of the 2% ketoconazole cream to the standard topical treatments was found to have reduced the Malassezia spp. population by 90%, and showed a clinical efficacy rate of 70%. Furthermore, a combination of azole agents and tacrolimus produced a synergistic anti-fungal effect against Malassezia spp. in vitro. A clinical trial using this drug combination conducted on the face and neck of patients with intractable AD showed a 66.6% efficacy rate in both the reduction of the flora and in clinical improvement. From these results it was evident that Malassezia is one of the factors exacerbating AD, and that removal of the organism results in an improvement in the clinical condition of the patient.

Striae distensae are a frequent skin condition associated with pregnancy, weight change or lack of skin elasticity. The aim of this research was to obtain a topical product containing herbal active ingredients with documented antioxidant and anti-inflammatory activity (Punica granatum seed oil and Croton lechleri resin extract) and demonstrate its positive effect on prevention and treatment of striae distensae. First, the cream base formulation was optimized through experimental design. Secondly, the cream containing the two active ingredients was investigated in an interventional nonrandomized clinical trial. The clinical outcome was assessed through biophysical parameters and ultrasonographic evaluation. The state of the skin was evaluated by biophysical measurements and ultrasonography at the beginning of the study and after 3 and 6 weeks. The experimental design was successfully used to set the best ranges for the technological and formulation factors to obtain a cosmetic formulation with optimal characteristics. The study of clinical efficacy on the optimal formulation revealed an increase in the dermis thickness, hydration and elasticity values in both groups after 6 weeks of cream application. The new oil-in-water cream containing P. granatum seed oil and C. lechleri resin extract can be helpful in the prevention or improving of skin changes associated with striae. PMID:28280300

The newest Nucleus CI processor, the CP900, has two new options to improve speech-in-noise perception: (1) use of an adaptive directional microphone (SCAN mode) and (2) wireless connection to MiniMic1 and MiniMic2 wireless remote microphones. An analysis was made of the absolute and relative benefits of these technologies in a real-world mimicking test situation. Speech perception was tested using an adaptive speech-in-noise test (sentences-in-babble noise). In session A, SRTs were measured in three conditions: (1) Clinical Map, (2) SCAN and (3) MiniMic1. Each was assessed for three distances between speakers and CI recipient: 1 m, 2 m and 3 m. In session B, the benefit of the use of MiniMic2 was compared to benefit of MiniMic1 at 3 m. A group of 13 adult CP900 recipients participated. SCAN and MiniMic1 improved performance compared to the standard microphone with a median improvement in SRT of 2.7-3.9 dB for SCAN at 1 m and 3 m, respectively, and 4.7-10.9 dB for the MiniMic1. MiniMic1 improvements were significant. MiniMic2 showed an improvement in SRT of 22.2 dB compared to 10.0 dB for MiniMic1 (3 m). Digital wireless transmission systems (i.e. MiniMic) offer a statistically and clinically significant improvement in speech perception in challenging, realistic listening conditions.

Health service costs and clinical gains of psychotherapy for personality disorders: a randomized controlled trial of day-hospital-based step-down treatment versus outpatient treatment at a specialist practice

PubMed Central

2013-01-01

Background Day-hospital-based treatment programmes have been recommended for poorly functioning patients with personality disorders (PD). However, more research is needed to confirm the cost-effectiveness of such extensive programmes over other, presumably simpler, treatment formats. Methods This study compared health service costs and psychosocial functioning for PD patients randomly allocated to either a day-hospital-based treatment programme combining individual and group psychotherapy in a step-down format, or outpatient individual psychotherapy at a specialist practice. It included 107 PD patients, 46% of whom had borderline PD, and 40% of whom had avoidant PD. Costs included the two treatment conditions and additional primary and secondary in- and outpatient services. Psychosocial functioning was assessed using measures of global (observer-rated GAF) and occupational (self-report) functioning. Repeated assessments over three years were analysed using mixed models. Results The costs of step-down treatment were higher than those of outpatient treatment, but these high costs were compensated by considerably lower costs of other health services. However, costs and clinical gains depended on the type of PD. For borderline PD patients, cost-effectiveness did not differ by treatment condition. Health service costs declined during the trial, and functioning improved to mild impairment levels (GAF > 60). For avoidant PD patients, considerable adjuvant health services expanded the outpatient format. Clinical improvements were nevertheless superior to the step-down condition. Conclusion Our results indicate that decisions on treatment format should differentiate between PD types. For borderline PD patients, the costs and gains of step-down and outpatient treatment conditions did not differ. For avoidant PD patients, the outpatient format was a better alternative, leaning, however, on costly additional health services in the early phase of treatment.

Recent research has highlighted the role of implicative dilemmas in a variety of clinical conditions. These dilemmas are a type of cognitive conflict, in which different aspects of the self are countered in such a way that a desired change in a personal dimension (eg, symptom improvement) may be hindered by the need of personal coherence in another dimension. The aim of this study was to summarize, using a meta-analytical approach, the evidence relating to the presence and the level of this conflict, as well as its relationship with well-being, in various clinical samples. A systematic review using multiple electronic databases found that out of 37 articles assessed for eligibility, nine fulfilled the inclusion criteria for meta-analysis. Random effects model was applied when computing mean effect sizes and testing for heterogeneity level. Statistically significant associations were observed between the clinical status and the presence of dilemmas, as well as level of conflict across several clinical conditions. Likewise, the level of conflict was associated with symptom severity. Results highlighted the clinical relevance and the transdiagnostic nature of implicative dilemmas. PMID:26675503

Role of Tai Chi in the treatment of rheumatologic diseases.

Wang, Chenchen

Rheumatologic diseases (e.g., fibromyalgia, osteoarthritis, and rheumatoid arthritis) consist of a complex interplay between biologic and psychological aspects, resulting in therapeutically challenging chronic conditions to control. Encouraging evidence suggests that Tai Chi, a multi-component Chinese mind-body exercise, has multiple benefits for patients with a variety of chronic disorders, particularly those with musculoskeletal conditions. Thus, Tai Chi may modulate complex factors and improve health outcomes in patients with chronic rheumatologic conditions. As a form of physical exercise, Tai Chi enhances cardiovascular fitness, muscular strength, balance, and physical function. It also appears to be associated with reduced stress, anxiety, and depression, as well as improved quality of life. Thus, Tai Chi can be safely recommended to patients with fibromyalgia, osteoarthritis, and rheumatoid arthritis as a complementary and alternative medical approach to improve patient well-being. This review highlights the current body of knowledge about the role of this ancient Chinese mind-body medicine as an effective treatment of rheumatologic diseases to better inform clinical decision-making for our patients.

This study was made through a systematic review of publications involving WBVE and the selected sports in two databases (Pubmed and PEDRo). It were identified 10 studies involving WBVE and sports (6 of soccer, 2 of diving and 2 of sport combat) with 156 subjects (80 soccer players, 32 divers and 44 combat athletes), with age from 17 to 44 years old. The use of WBVE has proven to be a safe and useful strategy to improve the physical conditions of players of different sports. These findings may have clinical relevance and should be considered as a strategy to be used to try improve the physical conditions of players.

To better understand and overcome difficulties with recruitment of adolescents with type 2 diabetes into clinical trials at three United States institutions, we reviewed recruitment and retention strategies in clinical trials of youth with various chronic conditions. We explored whether similar strategies might be applicable to pediatric patients with type 2 diabetes. We compiled data on recruitment and retention of adolescents with type 2 diabetes at three centers (National Institutes of Health, Bethesda, Maryland; Baylor College of Medicine, Houston, Texas; and Children's National Medical Center, Washington, DC) from January 2009 to December 2011. We also conducted a thorough literature review on recruitment and retention in adolescents with chronic health conditions. The number of recruited patients was inadequate for timely completion of ongoing trials. Our review of recruitment strategies in adolescents included monetary and material incentives, technology-based advertising, word-of-mouth referral, and continuous patient-research team contact. Cellular or Internet technology appeared promising in improving participation among youths in studies of various chronic conditions and social behaviors. Adolescents with type 2 diabetes are particularly difficult to engage in clinical trials. Monetary incentives and use of technology do not represent "magic bullets," but may presently be the most effective tools. Future studies should be conducted to explore motivation in this population. We speculate that (1) recruitment into interventional trials that address the main concerns of the affected youth (e.g., weight loss, body image, and stress management) combined with less tangible outcomes (e.g., blood glucose control) may be more successful; and (2) study participation and retention may be improved by accommodating patients' and caregivers' schedules, by scheduling study visits before and after working hours, and in more convenient locations than in medical facilities.

Massively parallel sequencing technology is revolutionizing approaches to genomic and genetic research. Since its advent, the scale and efficiency of Next-Generation Sequencing (NGS) has rapidly improved. In spite of this success, sequencing genomes or genomic regions with extremely biased base composition is still a great challenge to the currently available NGS platforms. The genomes of some important pathogenic organisms like Plasmodium falciparum (high AT content) and Mycobacterium tuberculosis (high GC content) display extremes of base composition. The standard library preparation procedures that employ PCR amplification have been shown to cause uneven read coverage particularly across AT and GC rich regions, leading to problems in genome assembly and variation analyses. Alternative library-preparation approaches that omit PCR amplification require large quantities of starting material and hence are not suitable for small amounts of DNA/RNA such as those from clinical isolates. We have developed and optimized library-preparation procedures suitable for low quantity starting material and tolerant to extremely high AT content sequences. We have used our optimized conditions in parallel with standard methods to prepare Illumina sequencing libraries from a non-clinical and a clinical isolate (containing ~53% host contamination). By analyzing and comparing the quality of sequence data generated, we show that our optimized conditions that involve a PCR additive (TMAC), produces amplified libraries with improved coverage of extremely AT-rich regions and reduced bias toward GC neutral templates. We have developed a robust and optimized Next-Generation Sequencing library amplification method suitable for extremely AT-rich genomes. The new amplification conditions significantly reduce bias and retain the complexity of either extremes of base composition. This development will greatly benefit sequencing clinical samples that often require amplification due to low mass of DNA starting material.

Monetary incentives and use of technology do not represent “magic bullets,” but may presently be the most effective tools. Future studies should be conducted to explore motivation in this population. We speculate that (1) recruitment into interventional trials that address the main concerns of the affected youth (e.g., weight loss, body image, and stress management) combined with less tangible outcomes (e.g., blood glucose control) may be more successful; and (2) study participation and retention may be improved by accommodating patients’ and caregivers’ schedules, by scheduling study visits before and after working hours, and in more convenient locations than in medical facilities.

Racial/ethnic minority groups remain underrepresented in clinical trials. Many strategies to increase minority recruitment focus on minority communities and emphasize common diseases such as hypertension. Scant literature focuses on minority recruitment to trials of less common conditions, often conducted in specialty clinics and dependent on physician referrals. We identified trust/mistrust of specialist physician investigators and institutions conducting medical research and consequent participant reluctance to participate in clinical trials as key-shared barriers across racial/ethnic groups. We developed a trust-based continuous quality improvement intervention to build trust between specialist physician investigators and community minority-serving physicians and ultimately potential trial participants. To avoid the inherent biases of non-randomized studies, we evaluated the intervention in the national Randomized Recruitment Intervention Trial (RECRUIT). This report presents the design of RECRUIT. Specialty clinic follow-up continues through April 2017. We hypothesized that specialist physician investigators and coordinators trained in the trust-based continuous quality improvement intervention would enroll a greater proportion of minority participants in their specialty clinics than specialist physician investigators in control specialty clinics. Specialty clinic was the unit of randomization. Using continuous quality improvement, the specialist physician investigators and coordinators tailored recruitment approaches to their specialty clinic characteristics and populations. Primary analyses were adjusted for clustering by specialty clinic within parent trial and matching covariates. RECRUIT was implemented in four multi-site clinical trials (parent trials) supported by three National Institutes of Health institutes and included 50 associated specialty clinics from these parent trials. Using current data, we have 88% power or greater to detect a 0.15 or greater difference from the currently observed control proportion adjusting for clustering. We detected no differences in baseline matching criteria between intervention and control specialty clinics (all p values > 0.17). RECRUIT was the first multi-site randomized control trial to examine the effectiveness of a trust-based continuous quality improvement intervention to increase minority recruitment into clinical trials. RECRUIT's innovations included its focus on building trust between specialist investigators and minority-serving physicians, the use of continuous quality improvement to tailor the intervention to each specialty clinic's specific racial/ethnic populations and barriers to minority recruitment, and the use of specialty clinics from more than one parent multi-site trial to increase generalizability. The effectiveness of the RECRUIT intervention will be determined after the completion of trial data collection and planned analyses.

Genetic testing now makes it possible to identify specific mutations that may lead to life-threatening cardiac arrhythmias. This article presents data from a qualitative research study that explored the subjective experiences of individuals and families with cardiogenetic conditions. We focus on describing patients' experiences of psychological stresses associated with having a cardiogenetic condition, illustrating the importance of integrating psychological and medical care. This integration of care is particularly important as personalized genomic medicine continues to evolve and the implications of genetic testing have a profound effect on individuals and families. The researchers interviewed 50 participants from 32 families. The research team used a systematic, grounded theory procedure to code and analyze interview and focus group transcripts, incorporating multiple coders at several stages of the data analysis process. Three major themes emerged: a bereavement trajectory associated with sudden death in the absence of prior symptoms; high anxiety about transmitting a genetic mutation; and resilience reflected in positive lifestyle changes and participation in support groups. This article identifies patient perspectives on personalized genomic medicine in cardiogenetics that can improve clinical care, including: specialized bereavement counseling; improving education about cardiogenetic conditions for medical professionals; parent guidelines for discussing cardiogenetic conditions with their children; information about support groups; and the routine inclusion of clinical psychologists in interdisciplinary treatment teams. Given recent advances in technology and decreasing costs, whole-genome sequencing is likely to become common practice in the near future. Therefore, these recommendations are likely to be relevant for other genetic conditions, as well as the entire field of personalized genomic medicine.

Tyrosine kinase inhibitors (TKIs) significantly improve survival in patients with chronic myeloid leukemia in chronic phase (CML-CP). Conditional probability provides survival information in patients who have already survived for a specific period of time after treatment. Cumulative response and survival data from 6 consecutive frontline TKI clinical trials were analyzed. Conditional probability was calculated for failure-free survival (FFS), transformation-free survival (TFS), event-free survival (EFS), and overall survival (OS) according to depth of response within 1 year of the initiation of TKIs, including complete cytogenetic response, major molecular response, and molecular response with a 4-log or 4.5-log reduction. A total of 483 patients with a median follow-up of 99.4 months from the initiation of treatment with TKIs were analyzed. Conditional probabilities of FFS, TFS, EFS, and OS for 1 additional year for patients alive after 12 months of therapy ranged from 92.0% to 99.1%, 98.5% to 100%, 96.2% to 99.6%, and 96.8% to 99.7%, respectively. Conditional FFS for 1 additional year did not improve with a deeper response each year. Conditional probabilities of TFS, EFS, and OS for 1 additional year were maintained at >95% during the period. In the era of TKIs, patients with chronic myeloid leukemia in chronic phase who survived for a certain number of years maintained excellent clinical outcomes in each age group.

Digital communication between a patient and their clinician offers the potential for improved patient care, particularly for young people with long term conditions who are at risk of service disengagement. However, its use raises a number of ethical questions which have not been explored in empirical studies. The objective of this study was to examine, from the patient and clinician perspective, the ethical implications of the use of digital clinical communication in the context of young people living with long-term conditions. A total of 129 semi-structured interviews, 59 with young people and 70 with healthcare professionals, from 20 United Kingdom (UK)-based specialist clinics were conducted as part of the LYNC study. Transcripts from five sites (cancer, liver, renal, cystic fibrosis and mental health) were read by a core team to identify explicit and implicit ethical issues and develop descriptive ethical codes. Our subsequent thematic analysis was developed iteratively with reference to professional and ethical norms. Clinician participants saw digital clinical communication as potentially increasing patient empowerment and autonomy; improving trust between patient and healthcare professional; and reducing harm because of rapid access to clinical advice. However, they also described ethical challenges, including: difficulty with defining and maintaining boundaries of confidentiality; uncertainty regarding the level of consent required; and blurring of the limits of a clinician's duty of care when unlimited access is possible. Paradoxically, the use of digital clinical communication can create dependence rather than promote autonomy in some patients. Patient participants varied in their understanding of, and concern about, confidentiality in the context of digital communication. An overarching theme emerging from the data was a shifting of the boundaries of the patient-clinician relationship and the professional duty of care in the context of use of clinical digital communication. The ethical implications of clinical digital communication are complex and go beyond concerns about confidentiality and consent. Any development of this form of communication should consider its impact on the patient-clinician-relationship, and include appropriate safeguards to ensure that professional ethical obligations are adhered to.

Long term follow up of idiopathic gingival enlargement associated with chronic periodontitis: A case report and review

Background: Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. Case Description: This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Clinical Implications: Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence. PMID:23869135

Current research on pycnodysostosis.

Turan, Serap

Pycnodysostosis is a rare autosomal recessive disorder caused by an inactivating mutation in cathepsin K (CTSK) and characterized by dysmorphic facial features, a short stature, acroosteolysis, osteosclerosis with increased bone fragility, and delayed closure of cranial sutures. Patients usually present with short stature or dysmorphic features the Pediatric Endocrinology or Genetics clinics, with atypical fractures to the orthopedics clinics or hematological abnormalities to the hematology clinics. However, under-diagnosis or misdiagnosis of this condition is a major issue. Pycnodysostosis is not a life threatening condition, but craniosynostosis, frequent fractures, respiratory-sleep problems, and dental problems may cause significant morbidity. Although no specific treatment for this disorder has been described, patients should be followed for complications and treated accordingly. A specific treatment for the disorder must be established in the future to prevent complications and improve quality of life for patients in the current era of advanced molecular research.

2013-01-01

The concurrent and predictive validity of 2 different methods of Millon Clinical Multiaxial Inventory–III subtyping (protocol sorting, cluster analysis) was evaluated in 125 recently detoxified opioid-dependent outpatients in a 12-week randomized clinical trial. Participants received naltrexone and relapse prevention group counseling and were assigned to 1 of 3 intervention conditions: (a) no-incentive vouchers, (b) incentive vouchers alone, or (c) incentive vouchers plus relationship counseling. Affective disturbance was the most common Axis I protocol-sorted subtype (66%), antisocial–narcissistic was the most common Axis II subtype (46%), and cluster analysis suggested that a 2-cluster solution (high vs. low psychiatric severity) was optimal. Predictive validity analyses indicated less symptom improvement for the higher problem subtypes, and patient treatment matching analyses indicated that some subtypes had better outcomes in the no-incentive voucher conditions.

This 12-month, open-label, flexible-dose study with an extension period evaluated the tolerability and efficacy of armodafinil in patients with excessive sleepiness associated with treated obstructive sleep apnea (OSA), shift work disorder (SWD), or narcolepsy. Armodafinil-naïve, adult patients with excessive sleepiness associated with treated OSA (n = 170), SWD (n = 108), or narcolepsy (n = 50) received armodafinil (100-250 mg) once daily (treated OSA or narcolepsy) or before night shifts (SWD). Patients with OSA were regular users of continuous positive airway pressure (CPAP) therapy. Efficacy measures included the Clinical Global Impression of Improvement (CGI-I) and the Epworth Sleepiness Scale (ESS). Across the diagnosis groups, the most commonly occurring adverse event was headache (14%-24%). Forty-three patients (13%) and 13 patients (4%) were withdrawn because of adverse events and insufficient efficacy, respectively. Armodafinil did not adversely affect CPAP therapy. At the final visit, 80% (95% CI: 74.1, 86.7) of patients with treated OSA and 84% (72.7, 94.8) of patients with narcolepsy were rated on the CGI-I as at least minimally improved with regard to overall clinical condition; 98% (95.2, 100.0) of patients with SWD were rated as improved with regard to sleepiness during night shifts, including the commute to and from work. Armodafinil improved ESS total scores in patients with treated OSA (mean [SD] [95% CI] change from baseline, -7.3 [5.6] [-8.39, -6.30]) and patients with narcolepsy (-4.7 [6.0] [-7.41, -1.93]). Armodafinil administered for 12 months or more was generally well tolerated and improved wakefulness in patients with excessive sleepiness associated with treated OSA, SWD, or narcolepsy. Armodafinil improved the overall clinical condition of patients with treated OSA or narcolepsy.

To determine whether an interactive self-management Website for people with chronic back pain would significantly improve emotional management, coping, self-efficacy to manage pain, pain levels, and physical functioning compared with standard text-based materials. The study utilized a pretest-posttest randomized controlled design comparing Website (painACTION-Back Pain) and control (text-based material) conditions at baseline and at 1-, 3, and 6-month follow-ups. Two hundred and nine people with chronic back pain were recruited through dissemination of study information online and at a pain treatment clinic. The 6-month follow-up rates for the Website and control groups were 73% and 84%, respectively. Measures were based on the recommendations of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials and included measures of pain intensity, physical functioning, emotional functioning, coping, self-efficacy, fear-avoidance, perceived improvement with treatment, self-efficacy, and catastrophizing. Compared with controls, painACTION-Back Pain participants reported significantly: 1) lower stress; 2) increased coping self-statements; and 3) greater use of social support. Comparisons between groups suggested clinically significant differences in current pain intensity, depression, anxiety, stress, and global ratings of improvement. Among participants recruited online, those using the Website reported significantly: 1) lower "worst" pain; 2) lower "average" pain; and 3) increased coping self-statements, compared with controls. Participants recruited through the pain clinic evidenced no such differences. An online self-management program for people with chronic back pain can lead to improvements in stress, coping, and social support, and produce clinically significant differences in pain, depression, anxiety, and global rates of improvement.

Contributions of change in clinical status parameters to Patient Global Impression of Change (PGIC) scores among persons with fibromyalgia treated with milnacipran.

2010-05-01

Clinical trials on the treatment of pain syndromes have adopted Patient Global Impression of Change (PGIC) as a primary outcome. However, little is known about how change in clinical status influences these ratings. The present study examined relationships between changes in pain, depressed mood, physical functioning, vitality, sleep disturbance, cognitive complaints, and PGIC ratings among 1260 participants with fibromyalgia (FM) who completed one of two trials examining the safety and efficacy of milnacipran. Many of the relationships between change in clinical status and PGIC ratings were stronger among persons who rated themselves as improved (responders) versus those reporting no change or a worsening of their condition (non-responders). Among non-responders, simultaneous regression analysis revealed that greater degrees of depressed mood and pain, and poorer physical function were significantly associated with worse PGIC ratings. Among responders, improvements in pain were significantly associated with better PGIC ratings, along with improvements in vitality, sleep, physical function, and cognitive complaints. These findings underscore the complexity of global ratings in FM patients, and suggest the association between clinical status and PGIC ratings varies as a function of perceived treatment response. Several domains were associated with PGIC ratings, highlighting the need to assess multiple outcomes in clinical trials of treatments for FM.

Basal thumb arthritis

Dias, Richard; Chandrasenan, Jeevan; Rajaratnam, Vaikunthan; Burke, Frank D

2007-01-01

Basal thumb arthritis is a common condition seen in hand clinics across the United Kingdom and is often associated with other pathological conditions such as carpal tunnel syndrome and scaphotrapezial arthritis. Typically, patients complain of pain localised to the base of the thumb. This pain is often activity related, particularly after excessive use involving forceful pinch. A detailed history and examination is normally all that is needed to make the diagnosis. Provocative manoeuvres may be helpful in localising symptoms to the basal joint with degenerative changes or synovitis. Radiographs are useful for confirming the diagnosis and staging the disease in order to plan for surgery. The mainstay of initial treatment of basal thumb arthritis of any stage is activity modifications, rest, nonsteroidal anti‐inflammatory drugs, exercises and splinting. A variety of surgical procedures are available to treat the condition when conservative measures have failed, in order to control symptoms and improve function. We review the current literature and discuss the clinical aspects of this condition, staging, and treatment options available, and the difficulties treating this group of patients. PMID:17267677

Discovery, development, and clinical application of sugammadex sodium, a selective relaxant binding agent

Welliver, Mark; McDonough, John; Kalynych, Nicholas; Redfern, Robert

2008-01-01

Neuromuscular blockade, induced by neuromuscular blocking agents, has allowed prescribed immobility, improved surgical exposure, optimal airway management conditions, and facilitated mechanical ventilation. However, termination of the effects of neuromuscular blocking agents has, until now, remained limited. A novel cyclodextrin encapsulation process offers improved termination of the paralytic effects of aminosteroidal non-depolarizing neuromuscular blocking agents. Sugammadex sodium is the first in a new class of drug called selective relaxant binding agents. Currently, in clinical trials, sugammadex, a modified gamma cyclodextrin, has shown consistent and rapid termination of neuromuscular blockade with few side effects. The pharmacology of cyclodextrins in general and sugammadex in particular, together with the results of current clinical research are reviewed. The ability of sugammadex to terminate the action of neuromuscular blocking agents by direct encapsulation is compared to the indirect competitive antagonism of their effects by cholinesterase inhibitors. Also discussed are the clinical implications that extend beyond fast, effective reversal, including numerous potential perioperative benefits. PMID:19920893

Management of boys and men with disorders of sex development.

2012-06-01

This review of disorders of sex development (DSDs) in boys and men will outline the conditions that may lead to this phenotype, present some guidance on how to evaluate and investigate affected cases and then review the medical and surgical management and subsequent outcome. DSDs are a wide range of relatively rare conditions which need multidisciplinary input. The underlying cause is clearer in girls with DSDs, but the actual diagnosis remains unclear in the majority of boys with DSDs. There is a need to improve the diagnostic yield and develop standardized methods for assessing, describing and investigating DSDs as well as for reporting outcome. This will lead to improved clinical management and genetic counselling.

"Mindfulness-based" interventions show promise for stress reduction in general medical conditions, and initial evidence suggests that they are accepted in trauma-exposed individuals. Mindfulness-based cognitive therapy (MBCT) shows substantial efficacy for prevention of depression relapse, but it has been less studied in anxiety disorders. This study investigated the feasibility, acceptability, and clinical outcomes of an MBCT group intervention adapted for combat posttraumatic stress disorder (PTSD). Consecutive patients seeking treatment for chronic PTSD at a VA outpatient clinic were enrolled in 8-week MBCT groups, modified for PTSD (four groups, n = 20) or brief treatment-as-usual (TAU) comparison group interventions (three groups, n = 17). Pre and posttherapy psychological assessments with clinician administered PTSD scale (CAPS) were performed with all patients, and self-report measures (PTSD diagnostic scale, PDS, and posttraumatic cognitions inventory, PTCI) were administered in the MBCT group. Intent to treat analyses showed significant improvement in PTSD (CAPS (t(19) = 4.8, P < .001)) in the MBCT condition but not the TAU conditions, and a significant Condition × Time interaction (F[1,35] = 16.4, P < .005). MBCT completers (n = 15, 75%) showed good compliance with assigned homework exercises, and significant and clinically meaningful improvement in PTSD symptom severity on posttreatment assessment in CAPS and PDS (particularly in avoidance/numbing symptoms), and reduced PTSD-relevant cognitions in PTCI (self blame). These data suggest group MBCT as an acceptable brief intervention/adjunctive therapy for combat PTSD, with potential for reducing avoidance symptom cluster and PTSD cognitions. Further studies are needed to examine efficacy in a randomized controlled design and to identify factors influencing acceptability and efficacy. © 2013 Wiley Periodicals, Inc.

To test whether a modified version of prolonged exposure (mPE) can effectively treat posttraumatic stress disorder (PTSD) in individuals with co-occurring PTSD and substance dependence, an efficacy trial was conducted in which substance dependent treatment-seekers with PTSD (N = 126, male = 54.0%, White = 79.4%) were randomly assigned to mPE, mPE + trauma-focused motivational enhancement session (mPE + MET-PTSD), or a health information-based control condition (HLS). All participants were multiply traumatized; the median number of reported traumas that satisfied DSM-IV Criterion A for PTSD was 8. Treatment consisted of 9-12 60-min individual therapy sessions plus substance abuse treatment-as-usual. Participants were assessed at baseline, end-of-treatment, and at 3- and 6-months posttreatment. Both the mPE and mPE + MET-PTSD conditions achieved significantly better PTSD outcome than the control condition. The mPE + MET-PTSD and mPE conditions did not differ from one another on PTSD symptoms at end of treatment, 3-, or 6-month follow-up. Substance use outcomes did not differ between groups with all groups achieving 85.7%-97.9% days abstinent at follow-up. In regard to clinically significant improvement in trauma symptoms, 75.8% of the mPE participants, 60.0% of the mPE + MET-PTSD participants, and 44.4% of the HLS participants experienced clinically significant improvement at the end-of-treatment. Results indicate mPE, with or without an MET-PTSD session, can effectively treat PTSD in patients with co-occurring PTSD and substance dependence. In addition, mPE session lengths may better suit standard clinical practice and are associated with medium effect sizes. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

2007-12-01

The aim of the present study was to compare the relative effectiveness of group and individual formats of a family-focused cognitive-behavioural intervention, for the treatment of childhood anxiety disorders. Twenty-nine clinically anxious children aged between 7 and 12 years were randomly allocated to either individual cognitive-behaviour therapy (ICBT) or group cognitive-behaviour therapy (GCBT). At post-treatment assessment 57% of children in the ICBT condition no longer met criteria for any anxiety disorder, compared to 47% of children in the GCBT condition. At 3 month follow up these improvements were retained with some weakening. By the 6 month follow up 50% of children in the ICBT compared to 53% of children in the GCBT condition were anxiety diagnosis free. In terms of questionnaire data, no significant differences were detected between the ICBT and GCBT conditions at any of the follow-up points. However, a significant treatment effect for time was found, with both self-reports and parent reports indicating a significant reduction over time in anxiety symptoms. Overall, results suggest that children with anxiety disorders appear to improve following a family-focused cognitive behavioural intervention, regardless of individual or group administration. The interpretation and potential clinical implications of these findings are discussed, together with the limitations of this study and suggestions for future research.

Selective GABA(A) α5 positive allosteric modulators improve cognitive function in aged rats with memory impairment.

2013-01-01

A condition of excess activity in the hippocampal formation is observed in the aging brain and in conditions that confer additional risk during aging for Alzheimer's disease. Compounds that act as positive allosteric modulators at GABA(A) α5 receptors might be useful in targeting this condition because GABA(A) α5 receptors mediate tonic inhibition of principal neurons in the affected network. While agents to improve cognitive function in the past focused on inverse agonists, which are negative allosteric modulators at GABA(A) α5 receptors, research supporting that approach used only young animals and predated current evidence for excessive hippocampal activity in age-related conditions of cognitive impairment. Here, we used two compounds, Compound 44 [6,6-dimethyl-3-(3-hydroxypropyl)thio-1-(thiazol-2-yl)-6,7-dihydro-2-benzothiophen-4(5H)-one] and Compound 6 [methyl 3,5-diphenylpyridazine-4-carboxylate], with functional activity as potentiators of γ-aminobutyric acid at GABA(A) α5 receptors, to test their ability to improve hippocampal-dependent memory in aged rats with identified cognitive impairment. Improvement was obtained in aged rats across protocols differing in motivational and performance demands and across varying retention intervals. Significant memory improvement occurred after either intracereboventricular infusion with Compound 44 (100 μg) in a water maze task or systemic administration with Compound 6 (3 mg/kg) in a radial arm maze task. Furthermore, systemic administration improved behavioral performance at dosing shown to provide drug exposure in the brain and in vivo receptor occupancy in the hippocampus. These data suggest a novel approach to improve neural network function in clinical conditions of excess hippocampal activity. This article is part of a Special Issue entitled 'Cognitive Enhancers'.

The analysis of blood constituents is a widely used tool to aid in monitoring of animal health and disease. However, classic blood diagnostics (i.e. hematologic and plasma biochemical values) often do not provide sufficient information to determine the state of an animal’s health. Field studies on wild tortoises and other reptiles have had limited success in drawing significant inferences between blood diagnostics and physiological and immunological condition. However, recent research using gene transcription profiling in the threatened Mojave desert tortoise (Gopherus agassizii) has proved useful in identifying immune or physiologic responses and overall health. To improve our understanding of health and immune function in tortoises, we evaluated both standard blood diagnostic (body condition, hematologic, plasma biochemistry values, trace elements, plasma proteins, vitamin A levels) and gene transcription profiles in 21 adult tortoises (11 clinically abnormal; 10 clinically normal) from Clark County, NV, USA. Necropsy and histology evaluations from clinically abnormal tortoises revealed multiple physiological complications, with moderate to severe rhinitis or pneumonia being the primary cause of morbidity in all but one of the examined animals. Clinically abnormal tortoises had increased transcription for four genes (SOD, MyD88, CL and Lep), increased lymphocyte production, biochemical enzymes and organics, trace elements of copper, and decreased numbers of leukocytes. We found significant positive correlations between increased transcription for SOD and increased trace elements for copper, as well as genes MyD88 and Lep with increased inflammation and microbial insults. Improved methods for health assessments are an important element of monitoring tortoise population recovery and can support the development of more robust diagnostic measures for ill animals, or individuals directly impacted by disturbance.

Evaluating the Impact of Classroom Education on the Management of Septic Shock Using Human Patient Simulation.

2016-02-01

Classroom lectures are the mainstay of imparting knowledge in a structured manner and have the additional goals of stimulating critical thinking, lifelong learning, and improvements in patient care. The impact of lectures on patient care is difficult to examine in critical care because of the heterogeneity in patient conditions and personnel as well as confounders such as time pressure, interruptions, fatigue, and nonstandardized observation methods. The critical care environment was recreated in a simulation laboratory using a high-fidelity mannequin simulator, where a mannequin simulator with a standardized script for septic shock was presented to trainees. The reproducibility of this patient and associated conditions allowed the evaluation of "clinical performance" in the management of septic shock. In a previous study, we developed and validated tools for the quantitative analysis of house staff managing septic shock simulations. In the present analysis, we examined whether measures of clinical performance were improved in those cases where a lecture on the management of shock preceded a simulated exercise on the management of septic shock. The administration of the septic shock simulations allowed for performance measurements to be calculated for both medical interns and for subsequent management by a larger resident-led team. The analysis revealed that receiving a lecture on shock before managing a simulated patient with septic shock did not produce scores higher than for those who did not receive the previous lecture. This result was similar for both interns managing the patient and for subsequent management by a resident-led team. We failed to find an immediate impact on clinical performance in simulations of septic shock after a lecture on the management of this syndrome. Lectures are likely not a reliable sole method for improving clinical performance in the management of complex disease processes.

To improve our understanding of health and immune function in tortoises, we evaluated both standard blood diagnostic (body condition, hematologic, plasma biochemistry values, trace elements, plasma proteins, vitamin A levels) and gene transcription profiles in 21 adult tortoises (11 clinically abnormal; 10 clinically normal) from Clark County, NV, USA. Necropsy and histology evaluations from clinically abnormal tortoises revealed multiple physiological complications, with moderate to severe rhinitis or pneumonia being the primary cause of morbidity in all but one of the examined animals. Clinically abnormal tortoises had increased transcription for four genes (SOD, MyD88, CL and Lep), increased lymphocyte production, biochemical enzymes and organics, trace elements of copper, and decreased numbers of leukocytes. We found significant positive correlations between increased transcription for SOD and increased trace elements for copper, as well as genes MyD88 and Lep with increased inflammation and microbial insults. Improved methods for health assessments are an important element of monitoring tortoise population recovery and can support the development of more robust diagnostic measures for ill animals, or individuals directly impacted by disturbance.

The analysis of blood constituents is a widely used tool to aid in monitoring of animal health and disease. However, classic blood diagnostics (i.e. hematologic and plasma biochemical values) often do not provide sufficient information to determine the state of an animal's health. Field studies on wild tortoises and other reptiles have had limited success in drawing significant inferences between blood diagnostics and physiological and immunological condition. However, recent research using gene transcription profiling in the threatened Mojave desert tortoise ( Gopherus agassizii ) has proved useful in identifying immune or physiologic responses and overall health. To improve our understanding of health and immune function in tortoises, we evaluated both standard blood diagnostic (body condition, hematologic, plasma biochemistry values, trace elements, plasma proteins, vitamin A levels) and gene transcription profiles in 21 adult tortoises (11 clinically abnormal; 10 clinically normal) from Clark County, NV, USA.

Sihoe, Alan D L

2016-02-01

A clinical pathway provides a scheduled, objective protocol for the multi-disciplinary, evidence-based management of patients with a specific condition or undergoing a specific procedure. In implementing a clinical pathway for the care of patients receiving video-assisted thoracic surgery (VATS) in Hong Kong, many insights were gained into what makes a clinical pathway work: meticulous preparation and team-building are keys to success; the pathway must be constantly reviewed and revisions made in response to evolving clinical need; and data collection is a key element to allow auditing and clinical research. If these can be achieved, a clinical pathway delivers not only measurable improvements in patient outcomes, but also fundamentally complements clinical advances such as VATS. This article narrates the story of how the clinical pathway for VATS in Hong Kong was created and evolved, highlighting how the above lessons were learned.

Mesenchymal stromal cells (MSCs) and endothelial progenitor cells (EPCs) are used in cell-based regenerative therapy. HMG CoA reductase inhibitors (statins) appear promising in blocking apoptosis, prolonging progenitor cell survival and improving their capacity to repair organ function. We performed a systematic review of preclinical and clinical studies to clarify whether statins can improve cell-based repair of organ injury. MEDLINE, EMBASE, and PUBMED databases were searched (1947 to June 25, 2013). Controlled clinical and pre-clinical studies were included that evaluated statin therapy used alone or in combination with MSCs or EPCs in patients or animals with organ injury. After screening 771 citations, 100 records underwent full eligibility screening of which 38 studies met eligibility and were included in the review: Studies were grouped into pre-clinical studies that involved statin treatment in combination with cell therapy (18 studies), preclinical studies of statin therapy alone (13 studies) and clinical studies of statin therapy (7 studies). Studies addressed cardiac injury (14 studies), vascular disorders (15 studies), neurologic conditions (8 studies) and bone fractures (1 study). Pre-clinical studies of statins in combination with MSC infusion (15 studies) or EPC therapy (3 studies) were described and despite marked heterogeneity in reporting outcomes of cellular analysis and organ function, all of these cell-based pre-clinical studies reported improved organ recovery with the addition of statin therapy. Moreover, 13 pre-clinical studies involved the administration of a statin drug alone to animals. An increase in EPC number and/or function (no studies of MSCs) was reported in 11 of these studies (85 %) and improved organ function in 12 studies (92 %). We also identified 7 clinical studies and none involved the administration of cells but described an increased number and/or function of EPCs (no studies of MSCs) and improved organ function with statin therapy (1.2-fold to 35-fold improvement over controls) in all 7 studies. Our systematic review provides a foundation of encouraging results that support further study of statins in regenerative therapy to augment the number and/or function of MSCs used in cell-based repair and to augment the number and function of EPCs in vivo to repair damaged tissues. Larger studies are needed to ensure safety and confirm clinical benefits.

Delayed Post-ischemic Conditioning Significantly Improves the Outcome after Retinal Ischemia

In previous studies, it was shown that post-conditioning, a transient period of brief ischemia following prolonged severe ischemia in the retina, could provide significant improvement in post-ischemic recovery, attenuation of cell loss, and decreased apoptosis. These studies showed that post-conditioning effectively prevented damage after retinal ischemia when it was instituted early (within one hour) in the post-ischemic period. While post-ischemic conditioning holds high promise of clinical translation, patients often present late after the onset of retinal ischemia and therefore immediate application of this anti-ischemic maneuver is generally not feasible. In this study, we examined the hypothesis that application of a post-conditioning stimulus at 24 h or greater following the end of prolonged ischemia would decrease the extent of ischemic injury. Ischemia was induced in rat retina in vivo. Recovery after ischemia followed by 5 minutes of post-conditioning brief ischemia 24 or 48 h after prolonged ischemia was assessed functionally (electroretinography) and histologically at 7 days after ischemia and post-conditioning or sham post-conditioning. We found that the brief ischemic stimulus applied 24, but not 48 h after prolonged ischemia significantly improved functional recovery and decreased histological damage induced by prolonged ischemia. We conclude that within a defined time window, delayed post-ischemic conditioning ameliorated post-ischemic injury in rats. Compared to earlier studies, the present work demonstrates for the first time the novel ability of a significantly delayed ischemic stimulus to provide robust neuroprotection in the retina following ischemia.

The minimum clinically important difference (MCID) is used to interpret the relevance of treatment effects, e.g., when developing clinical guidelines, evaluating trial results or planning sample sizes. There is currently no agreement on an appropriate MCID in chronic pain and little is known about which contextual factors cause variation. This is a systematic review. We searched PubMed, EMBASE, and Cochrane Library. Eligible studies determined MCID for chronic pain based on a one-dimensional pain scale, a patient-reported transition scale of perceived improvement, and either a mean change analysis (mean difference in pain among minimally improved patients) or a threshold analysis (pain reduction associated with best sensitivity and specificity for identifying minimally improved patients). Main results were descriptively summarized due to considerable heterogeneity, which were quantified using meta-analyses and explored using subgroup analyses and metaregression. We included 66 studies (31.254 patients). Median absolute MCID was 23 mm on a 0-100 mm scale (interquartile range [IQR] 12-39) and median relative MCID was 34% (IQR 22-45) among studies using the mean change approach. In both cases, heterogeneity was very high: absolute MCID I 2  = 99% and relative MCID I 2  = 96%. High variation was also seen among studies using the threshold approach: median absolute MCID was 20 mm (IQR 15-30) and relative MCID was 32% (IQR 15-41). Absolute MCID was strongly associated with baseline pain, explaining approximately two-thirds of the variation, and to a lesser degree with the operational definition of minimum pain relief and clinical condition. A total of 15 clinical and methodological factors were assessed as possible causes for variation in MCID. MCID for chronic pain relief vary considerably. Baseline pain is strongly associated with absolute, but not relative, measures. To a much lesser degree, MCID is also influenced by the operational definition of relevant pain relief and possibly by clinical condition. Explicit and conscientious reflections on the choice of an MCID are required when classifying effect sizes as clinically important or trivial. Copyright © 2018 Elsevier Inc. All rights reserved.

The preanalytic phase in veterinary clinical pathology.

This article presents the general causes of preanalytic variability with a few examples showing specialists and practitioners that special and improved care should be given to this too often neglected phase. The preanalytic phase of clinical pathology includes all the steps from specimen collection to analysis. It is the phase where most laboratory errors occur in human, and probably also in veterinary clinical pathology. Numerous causes may affect the validity of the results, including technical factors, such as the choice of anticoagulant, the blood vessel sampled, and the duration and conditions of specimen handling. While the latter factors can be defined, influence of biologic and physiologic factors such as feeding and fasting, stress, and biologic and endocrine rhythms can often not be controlled. Nevertheless, as many factors as possible should at least be documented. The importance of the preanalytic phase is often not given the necessary attention, although the validity of the results and consequent clinical decision making and medical management of animal patients would likely be improved if the quality of specimens submitted to the laboratory was optimized. © 2014 American Society for Veterinary Clinical Pathology.

Sleator, R D; Hill, C

2008-02-01

The increasing incidence of antibiotic resistance, coupled with a growing prevalence of cancer and allergic conditions in an aging population, has forced clinical research to explore alternative therapeutic and prophylactic avenues. One such approach involves the use of probiotics: beneficial bacterial cultures, which, when administered as a part of the daily dietary intake, reduce the incidence and severity of acute and chronic infection, facilitate prevention and reduced recurrence of certain cancers and lower the incidence of several atopic conditions. Herein, we review the most recent advances in the emerging area of patho-biotechnology in the context of improving probiotic production, delivery and clinical efficacy, in addition to the emerging area of 'designer probiotics'- strains specifically tailored to target certain pathogens and/or toxins in vivo.

The admission process of patients to a hospital is the starting point for inpatient services. In order to optimize the quality of the health services provision, one needs a good understanding of the patient admission workflow in a clinic. The aim of this study was to identify challenges and potential improvements in the admission process of spinal cord injury patients at a specialized rehabilitation clinic from the perspective of an interdisciplinary team of health professionals. Semi-structured interviews with eight health professionals (medical doctors, physical therapists, occupational therapists, nurses) at the Swiss Paraplegic Centre (acute and rehabilitation clinic) were conducted based on a maximum variety purposive sampling strategy. The interviews were analyzed using a thematic analysis approach. The interviewees described the challenges and potential improvements in this admission process, focusing on five themes. First, the characteristics of the patient with his/her health condition and personality and his/her family influence different areas in the admission process. Improvements in the exchange of information between the hospital and the patient could speed up and simplify the admission process. In addition, challenges and potential improvements were found concerning the rehabilitation planning, the organization of the admission process and the interdisciplinary work. This study identified five themes of challenges and potential improvements in the admission process of spinal cord injury patients at a specialized rehabilitation clinic. When planning adaptations of process steps in one of the areas, awareness of effects in other fields is necessary. Improved pre-admission information would be a first important step to optimize the admission process. A common IT-system providing an interdisciplinary overview and possibilities for interdisciplinary exchange would support the management of the admission process. Managers of other hospitals can supplement the results of this study with their own process analyses, to improve their own patient admission processes.

The intervention employs exemplification theory and the Elaboration Likelihood Model of persuasion to improve the match between breast cancer risk and mammography intentions. 2918 women ages 35-49 were stratified into two levels of 10-year breast cancer risk (<1.5%; ≥1.5%) then randomly assigned to one of eight conditions: two comparison conditions and six risk-based intervention conditions that varied according to a 2 (amount of content: brief vs. extended) x 3 (format: expository vs. untailored exemplar [example case] vs. tailored exemplar) design. Outcomes included mammography intentions and accuracy of perceived breast cancer risk. Risk-based intervention conditions improved the match between objective risk estimates and perceived risk, especially for high-numeracy women with a 10-year breast cancer risk ≤1.5%. For women with a risk≤1.5%, exemplars improved accuracy of perceived risk and all risk-based interventions increased intentions to wait until age 50 to screen. A risk-based mammography intervention improved accuracy of perceived risk and the match between objective risk estimates and mammography intentions. Interventions could be applied in online or clinical settings to help women understand risk and make mammography decisions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to test the hypothesis that a gaze-controlled communication system (eye tracker, ET) can improve communication processes between completely dysarthric ICU patients and the hospital staff, in three main domains: 1) basic communication processes (i.e., fundamental needs, desire, and wishes); 2) the ability of the medical staff to understand the clinical condition of the patient; and 3) the level of frustration experienced by patient, nurses and physicians. Fifteen fully conscious medical and surgical patients, 8 physicians, and 15 nurses were included in the study. The experimental procedure was composed by three phases: in phase 1 all groups completed the preintervention questionnaire; in phase 2 the ET was introduced and tested as a communication device; in phase 3 all groups completed the postintervention questionnaire. Patients preintervention questionnaires showed remarkable communication deficits, without any group effect. Answers of physicians and nurses were pretty much similar to the one of patients. Postintervention questionnaires showed in all groups a remarkable and statistically significant improvement in different communication domains, as well as a remarkable decrease of anxiety and disphoric thought. Improvement was also reported by physicians and nurses in their ability to understand patient's clinical conditions. Our results show an improvement in the quality of the examined parameters. Better communication processes seem also to lead to improvements in several psychological parameters, namely anxiety and drop-out depression perceived by both patients and medical staff. Further controlled studies are needed to define the ET role in ICU.

When students create teaching materials, learning can be enhanced. Therefore, a project was designed based on the traditional clinical case report and the chiropractic technique and principles curriculum at the University of Bridgeport College of Chiropractic. The objectives were to increase mastery in a clinical topic, increase awareness of different patient presentations and management options, and enhance information technology skills. Following lectures about the components of a case report and neurological reflexes related to visceral comorbidities and subluxation and joint dysfunction, students created a case report based on a template provided by the instructor. A survey gathered student perspectives on the exercise. More than 70% of the surveyed students felt the project was at least moderately helpful in improving understanding of a case report, the condition investigated, their clinical reasoning, and the ability to integrate information. Most felt that they improved their understanding of neurological reflexes, use of the literature, and the practice of evidence-based care. The majority believed that they identified weakness in knowledge, improved self-learning skills, and increased confidence in managing patients. Most enjoyed it at least somewhat and 70% agreed that the project should be continued. Many believed that they were better prepared for national boards and had improved their writing skills.

Biomedical research suffers from a dramatically poor translational success. For example, in ischemic stroke, a condition with a high medical need, over a thousand experimental drug targets were unsuccessful. Here, we adopt methods from clinical research for a late-stage pre-clinical meta-analysis (MA) and randomized confirmatory trial (pRCT) approach. A profound body of literature suggests NOX2 to be a major therapeutic target in stroke. Systematic review and MA of all available NOX2(-/y) studies revealed a positive publication bias and lack of statistical power to detect a relevant reduction in infarct size. A fully powered multi-center pRCT rejects NOX2 as a target to improve neurofunctional outcomes or achieve a translationally relevant infarct size reduction. Thus stringent statistical thresholds, reporting negative data and a MA-pRCT approach can ensure biomedical data validity and overcome risks of bias.

Recent technological improvements have increased the use of genetic testing in the clinic. This review serves to summarize the many practical benefits of genetic testing, discusses various methodologies that can be used clinically, and exemplifies ways in which genetics is propelling the field forward in nephrology. The advent of next-generation sequencing and microarray technologies has heralded an unprecedented number of discoveries in the field of nephrology, providing many opportunities for incorporating genomic diagnostics into clinical care. The use of genetic testing, particularly in pediatrics, can provide accurate diagnoses in puzzling cases, resolve misclassification of disease, and identify subsets of individuals with treatable conditions. Genetic testing may have broad benefits for patients and their families. Knowing the precise molecular etiology of disease can help clinicians determine the exact therapeutic course, and counsel patients and their families about prognosis. Genetic discoveries can also improve the classification of kidney disease and identify new targets for therapy.

Mindfulness Training Alters Emotional Memory Recall Compared to Active Controls: Support for an Emotional Information Processing Model of Mindfulness

2012-01-01

Objectives: While mindfulness-based interventions have received widespread application in both clinical and non-clinical populations, the mechanism by which mindfulness meditation improves well-being remains elusive. One possibility is that mindfulness training alters the processing of emotional information, similar to prevailing cognitive models of depression and anxiety. The aim of this study was to investigate the effects of mindfulness training on emotional information processing (i.e., memory) biases in relation to both clinical symptomatology and well-being in comparison to active control conditions. Methods: Fifty-eight university students (28 female, age = 20.1 ± 2.7 years) participated in either a 12-week course containing a “meditation laboratory” or an active control course with similar content or experiential practice laboratory format (music). Participants completed an emotional word recall task and self-report questionnaires of well-being and clinical symptoms before and after the 12-week course. Results: Meditators showed greater increases in positive word recall compared to controls [F(1, 56) = 6.6, p = 0.02]. The meditation group increased significantly more on measures of well-being [F(1, 56) = 6.6, p = 0.01], with a marginal decrease in depression and anxiety [F(1, 56) = 3.0, p = 0.09] compared to controls. Increased positive word recall was associated with increased psychological well-being (r = 0.31, p = 0.02) and decreased clinical symptoms (r = −0.29, p = 0.03). Conclusion: Mindfulness training was associated with greater improvements in processing efficiency for positively valenced stimuli than active control conditions. This change in emotional information processing was associated with improvements in psychological well-being and less depression and anxiety. These data suggest that mindfulness training may improve well-being via changes in emotional information processing. Future research with a fully randomized design will be needed to clarify the possible influence of self-selection. PMID:22347856

Notifiable condition reporting practices: implications for public health agency participation in a health information exchange.

The future of notifiable condition reporting in the United States is undergoing a transformation with the increasing development of Health Information Exchanges which support electronic data-sharing and -transfer networks and the wider adoption of electronic laboratory reporting. Communicable disease report forms originating in clinics are an important source of surveillance data for public health agencies. However, problems of poor data quality and delayed submission of reports to public health agencies are common. In addition, studies of barriers and facilitators to reporting have assumed that the primary reporter is the treating physician, although the extent to which a provider is involved in the reporting workflow is unclear. We sought to better understand the barriers to and burden of notifiable condition reporting from the perspectives of the three primary groups involved in reporting workflow: providers, clinic staff who bear the principal responsibility for reporting, and the public health workers who receive and process reports from clinics. In addition, we sought to situate these findings within the context of the future of notifiable disease reporting and the potential impacts of electronic lab and medical records on the surveillance system. Seven ambulatory care clinics and 3 public health agencies that are part of a Health Information Exchange in the state of Indiana, USA, participated in the study. Data were obtained from a survey of clinic physicians (N = 29), interviews with clinic reporters (N = 11), and interviews with public health workers (N = 9). Survey data were summarized descriptively and interview transcripts underwent qualitative analysis. In both clinics and public health agencies, the laboratory report initiates reporting workflow. Provider involvement with reporting primarily revolves around ordering medications to treat a condition confirmed by the lab result. In clinics, reporting is typically the responsibility of clinic reporters who vary in frequency of reporting. We found an association between frequency of reporting, reporting knowledge and perceptions of reporting burden. In both clinics and public health agencies, interruptions and delays in reporting workflow are encountered due to inaccurate or missing information and impact reporting timeliness, data quality and report completeness. Both providers and clinic reporters lack clarity regarding how data submitted by their reports are used by public health agencies. It is possible that the value of reporting may be diminished when those responsible do not perceive receiving benefit in return. This may account for the low awareness of or recollection of public health communications with clinics that we observed. Despite the high likelihood that public health advisories and guidance are based, in part, on data submitted by clinics, a direct concordance may not be recognized. Unlike most studies of notifiable condition reporting, this study included the clinic reporters who bear primary responsibility for completing and submitting reports to public health agencies. A primary barrier to this reporting is timely and easy access to data. It is possible that expanded adoption of electronic health record and laboratory reporting systems will improve access to this data and reduce reporting the burden. However, a complete reliance on automatic electronic extraction of data requires caution and necessitates continued interfacing with clinic reporters for the foreseeable future-particularly for notifiable conditions that are high-impact, uncommon, prone to false positive readings by labs, or are hard to verify. An important finding of this study is the association between frequency of reporting, reporting knowledge and perceptions of reporting burden. Increased automation could result in even lower reporting knowledge and familiarity with reporting requirements which could actually increase reporters' perception of notifiable condition reporting as burdensome. Another finding was of uncertainty regarding how data sent to public health agencies is used or provides clinical benefit. A strong recommendation generated by these findings is that, given their central role in reporting, clinic reporters are a significant target audience for public health outreach and education that aims to alleviate perceived reporting burden and improve reporting knowledge. In particular, communicating the benefits of public health's use of the data may reduce a perceived lack of information reciprocity between clinical and public health organizations.

Patients with fibromyalgia have diminished levels of physical fitness, which may lead to functional disability and exacerbating complaints. Multidisciplinary treatment comprising cognitive-behavioural therapy (CBT) and exercise training has been shown to be effective in improving physical fitness. However, due to the high drop-out rates and large variability in patients' functioning, it was proposed that a tailored treatment approach might yield more promising treatment outcomes. High-risk fibromyalgia patients were randomly assigned to a waiting list control group (WLC) or a treatment condition (TC), with the treatment consisting of 16 twice-weekly sessions of CBT and exercise training tailored to the patient's cognitive-behavioural pattern. Physical fitness was assessed with two physical tests before and 3 months after treatment and at corresponding intervals in the WLC. Treatment effects were evaluated using linear mixed models. The level of physical fitness had improved significantly in the TC compared with the WLC. Attrition rates were low, effect sizes large and reliable change indices indicated a clinically relevant improvement among the TC. A tailored multidisciplinary treatment approach for fibromyalgia consisting of CBT and exercise training is well tolerated, yields clinically relevant changes, and appears a promising approach to improve patients' physical fitness.

National Health Service (NHS) 111, a medical helpline for urgent care used within the England and Scotland, receives significant numbers of patient calls yearly for a range of clinical conditions. Some are considered high acuity and mainly directed to urgent and emergency care. Low acuity conditions are also directed to these costly, overburdened services. Community pharmacy is a recognised setting for effective low acuity condition management and could offer an alternative. To design and evaluate a new NHS111 pathway re-directing patients with low acuity conditions to community pharmacy. Two consensus development stakeholder workshops were undertaken. A "low acuity" condition was defined as one that can be clinically assessed by a community pharmacist and requires a treatment and/or advice available within a community pharmacy. Retrospective NHS111 patient data (February-August 2016) from the North East of England and access to the NHS Pathways clinical decision support software were available to stakeholders. The NHS111 data demonstrated the volume of patient calls for these conditions that could have been redirected to community pharmacy. Stakeholders reached consensus that 64 low acuity conditions could be safely redirected to community pharmacy via NHS111. This represented approximately 35,000 patients (11.5% of total) being shifted away from the higher cost settings in the North East region alone during February-August 2016. The stakeholder group discussions provided rationale behind their classifications of conditions to ensure patient safety, the care experience and added value. The resulting definitive list of low acuity conditions that could be directed to community pharmacy via NHS111 could result in a shift of workload from urgent and emergency care settings. Future work needs to evaluate the cost, clinical outcomes, patient satisfaction of a community pharmacy referral service that has the potential to improve integration of community pharmacy in the wider NHS.

Background The aim of the Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Family Practice (BETTER) randomized controlled trial is to improve the primary prevention of and screening for multiple conditions (diabetes, cardiovascular disease, cancer) and some of the associated lifestyle factors (tobacco use, alcohol overuse, poor nutrition, physical inactivity). In this article, we describe how we harmonized the evidence-based clinical practice guideline recommendations and patient tools to determine the content for the BETTER trial. Methods We identified clinical practice guidelines and tools through a structured literature search; we included both indexed and grey literature. From these guidelines, recommendations were extracted and integrated into knowledge products and outcome measures for use in the BETTER trial. End-users (family physicians, nurse practitioners, nurses and dieticians) were engaged in reviewing the recommendations and tools, as well as tailoring the content to the needs of the BETTER trial and family practice. Results In total, 3–5 high-quality guidelines were identified for each condition; from these, we identified high-grade recommendations for the prevention of and screening for chronic disease. The guideline recommendations were limited by conflicting recommendations, vague wording and different taxonomies for strength of recommendation. There was a lack of quality evidence for manoeuvres to improve the uptake of guidelines among patients with depression. We developed the BETTER clinical algorithms for the implementation plan. Although it was difficult to identify high-quality tools, 180 tools of interest were identified. Interpretation The intervention for the BETTER trial was built by integrating existing guidelines and tools, and working with end-users throughout the process to increase the intervention’s utility for practice.

Saccharomyces boulardii is a well-known probiotic worldwide, and there are numerous studies including experimental and clinical trials in children and adults by the use of S. boulardii. The objective of the present report is to provide an update on the evidence for the efficacy of S. boulardii CNCM I-745 in different clinical conditions. Saccharomyces boulardii is one of the best-studied probiotics in acute gastroenteritis (AGE) and is shown to be safe and to reduce the duration of diarrhea and hospitalization by about 1 day. Saccharomyces boulardii is one of the recommended probiotics for AGE in children by European Society of Paediatric Infectious Diseases and European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Saccharomyces boulardii is also a recommended probiotic for the prevention of antibiotic-associated diarrhea (AAD), and a recent study showed promising results for the treatment of AAD in children. There is insufficient evidence to recommend the long-term use of S. boulardii in patients with irritable bowel syndrome. Although some clinical studies showed positive effects of S. boulardii on inflammation, there is no clinical evidence that S. boulardii is useful in inflammatory bowel disease. Saccharomyces boulardii could be used in patients needing Helicobacter pylori eradication because the S. boulardii improves compliance, decreases the side effects and moderately increases the eradication rate. There are new promising results (improving feeding tolerance, shorten the course of hyperbilirubinemia), but we do still not recommend the routine use of S. boulardii in newborns. Saccharomyces boulardii CNCM I-745 is a good example for the statement that each probiotic needs to be taxonomically characterized and its efficacy and safety should be documented individually in different clinical settings.

Chronic kidney disease (CKD) is a serious long-term condition, which if left untreated causes significant cardiovascular sequele. It is well recognized management of modifiable risk factors, such as blood pressure (BP), can lead to improved long-term outcomes. A novel information technology (IT) solution presents a possible solution to help clinicians in the community identify and manage at risk patients more efficiently. The IMproving Patient care and Awareness of Kidney disease progression Together (IMPAKT) IT tool was used to identify patients with CKD and uncontrolled hypertension in the community. A CKD nurse utilized the tool at primary care practices to identify patients who warranted potential intervention and disseminated this information to clinical staff. Blood pressure management targets and incidence of coded CKD were used to evaluate the project. Altogether 48 practices participated in an 18 month project from April 2014, and data from 20 practices, with a total adult population of 121,362, was available for analysis. Two full consecutive QI (Quality Improvement) audit cycles were completed. There was an increase in the mean recorded prevalence of coded CKD patients over the course of the project. Similarly, there was an increase in the percentage of patients with BP been recorded and importantly there was an accompanying significant increase in CKD patients achieving BP targets. At the end of the project an additional 345 individuals with CKD achieved better blood pressure control. This could potentially prevent 9 cardiovascular events in the CKD group, translating to a cost saving of £320,000 for the 20 practices involved. The most significant change in clinical markers occurred during cycle 1 of the audit, the improvement was maintained throughout cycle 2 of the audit. Our results show the real-life clinical impact of a relatively simple and easy to implement QI project, to help improve outcomes in patients with CKD. This was achieved through more efficient working by targeting of high-risk groups, and improved communication between primary/secondary care. The project could be adapted for other chronic disease conditions. Despite the recorded improvements in blood pressure management, a large proportion of high-risk patients remained above ideal blood pressure, additional interventions in this area need to be explored. Through collaborative and multi-professional working and utilizing IT resources, we have shown it is possible to deliver measurable and sustainable improvements in blood pressure control for patients with CKD in a real life clinical setting.

Attention bias modification training (ABMT) is a promising treatment for anxiety disorders. Recent evidence suggests that attention training towards positive stimuli, using visual-search based ABMT, has beneficial effects on anxiety and attention biases in children. The present study extends this prior research using distinctive techniques designed to increase participant learning, memory consolidation, and treatment engagement. Fifty-nine clinically anxious children were randomly assigned to the active treatment condition (ATC) (N = 31) or waitlist control condition (WLC) (N = 28). In the ATC, children completed 12 treatment sessions at home on computer in which they searched matrices for a pleasant or calm target amongst unpleasant background pictures, while also engaging in techniques designed to consolidate learning and memory for these search strategies. No contact was made with children in the WLC during the wait period. Diagnostic, parent- and child-reports of anxiety and depressive symptoms, externalising behaviour problems and attention biases were assessed pre- and post-condition and six-months after treatment. Children in the ATC showed greater improvements on multiple clinical measures compared to children in the WLC. Post-treatment gains improved six-months after treatment. Attention biases for angry and happy faces did not change significantly from pre-to post-condition. However, larger pre-treatment attention bias towards threat was associated with greater reduction in anxiety at post-treatment. Also, children who showed greater consolidation of learning and memory strategies during treatment achieved greater improvement in global functioning at post-treatment. Attention training towards positive stimuli using enhanced visual-search procedures appears to be a promising treatment for childhood anxiety disorders. Copyright © 2015 Elsevier Ltd.

To evaluate the effectiveness of prospective review of orders for fresh-frozen plasma (FFP) and platelets in reducing blood-product use, and of the effectiveness of preparing pathology residents to serve as clinical consultants. At our 572-bed tertiary-care hospital, we developed guidelines for the use of blood products in collaboration with a variety of departments. For patients whose condition(s) met generally accepted criteria, we identified trigger points to allow for quick release by blood bank staff of blood products. For patients whose condition(s) did not meet the applicable criteria, the on-call pathology resident reviewed the medical record of that patient to determine whether there were any extenuating circumstances; consulted with the ordering physician and attending pathologist, as needed; and advised the house staff on appropriate use of blood products. We evaluated the change in use of blood products between the years 2009 and 2012 to assess the effectiveness of the program. We observed a decrease of 38.8% and 31.4% in the use of FFP and platelets, respectively (29.7% and 21.1%, respectively, when normalized for the number of discharges). If projected to the national level, this improvement would translate to an annual cost reduction of approximately $130 million. Prospective review of orders for blood products can significantly improve use of these products, thereby reducing risk to patients and avoiding unnecessary healthcare costs. The involvement of pathology residents in the prospective review process provides an excellent opportunity for their training as laboratory consultants.

Though cupping therapy has been used in China for thousands of years, there has been no systematic summary of clinical research on it.This review is to evaluate the therapeutic effect of cupping therapy using evidence-based approach based on all available clinical studies. We included all clinical studies on cupping therapy for all kinds of diseases. We searched six electronic databases, all searches ended in December 2008. We extracted data on the type of cupping and type of diseases treated. 550 clinical studies were identified published between 1959 and 2008, including 73 randomized controlled trials (RCTs), 22 clinical controlled trials, 373 case series, and 82 case reports. Number of RCTs obviously increased during past decades, but the quality of the RCTs was generally poor according to the risk of bias of the Cochrane standard for important outcome within each trials. The diseases in which cupping was commonly employed included pain conditions, herpes zoster, cough or asthma, etc. Wet cupping was used in majority studies, followed by retained cupping, moving cupping, medicinal cupping, etc. 38 studies used combination of two types of cupping therapies. No serious adverse effects were reported in the studies. According to the above results, quality and quantity of RCTs on cupping therapy appears to be improved during the past 50 years in China, and majority of studies show potential benefit on pain conditions, herpes zoster and other diseases. However, further rigorous designed trials in relevant conditions are warranted to support their use in practice.

Neurological and psychiatric disorders are characterized by several disabling symptoms for which effective, mechanism-based treatments remain elusive. Consequently, more advanced non-invasive therapeutic methods are required. A method that may modulate brain activity and be viable for use in clinical practice is repetitive transcranial magnetic stimulation (rTMS). It is a non-invasive procedure whereby a pulsed magnetic field stimulates electrical activity in the brain. Here, we focus on the basic foundation of rTMS, the main stimulation parametters, the factors that influence individual responses to rTMS and the experimental advances of rTMS that may become a viable clinical application to treat neurological and psychiatric disorders. The findings showed that rTMS can improve some symptoms associated with these conditions and might be useful for promoting cortical plasticity in patients with neurological and psychiatric disorders. However, these changes are transient and it is premature to propose these applications as realistic therapeutic options, even though the rTMS technique has been evidenced as a potential modulator of sensorimotor integration and neuroplasticity. Functional imaging of the region of interest could highlight the capacity of rTMS to bring about plastic changes of the cortical circuitry and hint at future novel clinical interventions. Thus, we recommend that further studies clearly determine the role of rTMS in the treatment of these conditions. Finally, we must remember that however exciting the neurobiological mechanisms might be, the clinical usefulness of rTMS will be determined by its ability to provide patients with neurological and psychiatric disorders with safe, long-lasting and substantial improvements in quality of life.

Bipolar disorder (BD) is intricately associated with chronic clinical conditions. Medical comorbidity is not only more prevalent in mood disorders, but is associated with increased costs, cognitive impairment and, ultimately, premature mortality. Oxidative stress and inflammation may mediate part of this association. To further investigate the association between medical comorbidity status and clinical improvement with adjuvant N acetyl cysteine (NAC) in the context of a placebo-controlled trial. Placebo-controlled randomized clinical trial assessing the effect of NAC over 24 weeks. Symptomatic and functional outcomes were collected over the study period. Medical comorbidities were self-reported, and we took special interest in cardiovascular and endocrine conditions. We evaluated change from baseline to endpoint and the interaction between change and reported medical comorbidities. Fifty-one percent of patients reported have a cardiovascular or endocrine comorbidity. Although not found for depressive symptoms or quality of life, a significant interaction between medical comorbidity and change scores was consistently found for all functional outcomes. This indicated an advantage of NAC over placebo in those with a clinical comorbidity. Systemic illness moderated only the effect of NAC on functioning, not on depression. Demonstrating an improvement in functional outcomes with an agent that modulates redox and inflammatory pathways, this study lends empirical support to the idea that medical and psychiatric comorbidity are additive in contributing to allostatic states. One intriguing possibility is that comorbid clinical illness could be a marker for more severe oxidative stress states--and thus guide antioxidant use--in BD. Copyright © 2011 Elsevier Inc.

Testosterone levels decrease with age. This decline is steeper during "critical illnesses". Cardiac surgery is a particular representative model of major clinical condition producing stress responses similar to those observed during severe nonsurgical illness. Cardiac revascularization with extracorporeal circulation is characterized by marked postoperative complications such as insulin resistance, a pro-inflammatory state, acute anemia and renal dysfunction. These phenomena are more evident in older subjects, who are particularly vulnerable in the post-operative state, a condition that has been recently termed as "acute postoperative frailty". We recently showed that in older men with low ejection fraction undergoing cardiac revascularization with extracorporeal circulation, there is a profound decline in anabolic hormones, including testosterone. After surgery testosterone concentration frequently declines to less than 200 ng/dl, a situation suggestive of overt hypogonadism. Since men with low testosterone levels have a high probability of developing mobility limitations, we considered this a rationale for the perioperative use of testosterone treatment in older men undergoing cardiac revasularization surgery. We hypothesized that testosterone supplementation at this time might attenuate the impressive post-surgical catabolic hormonal milieu. The aim of this manuscript is to elucidate an ongoing randomized clinical trial in older men (70+ years old) undergoing elective cardiovascular revascularization with extracorporeal circulation. This randomized clinical trial will evaluate the effects of intramuscular testosterone administration on clinical and functional outcomes in this population. The study will also address potential mechanisms underlying the expected beneficial effects of testosterone supplementation including improvement of insulin sensitivity, markers of inflammatory status and improved hemoglobin levels.

2013-09-01

Stereoscopic chest biplane correlation imaging (stereo∕BCI) has been proposed as an alternative modality to single view chest x-ray (CXR). The metrics effective modulation transfer function (eMTF), effective normalized noise power spectrum (eNNPS), and effective detective quantum efficiency (eDQE) have been proposed as clinically relevant metrics for assessing clinical system performance taking into consideration the magnification and scatter effects. This study compared the metrics eMTF, eNNPS, eDQE, and detectability index for stereo∕BCI and single view CXR under isodose conditions at two magnifications for two anthropomorphic phantoms of differing sizes. Measurements for the eMTF were taken for two phantom sizes with an opaque edge test device using established techniques. The eNNPS was measured at two isodose conditions for two phantoms using established techniques. The scatter was measured for two phantoms using an established beam stop method. All measurements were also taken at two different magnifications with two phantoms. A geometrical phantom was used for comparison with prior results for CXR although the results for an anatomy free phantom are not expected to vary for BCI. Stereo∕BCI resulted in improved metrics compared to single view CXR. Results indicated that magnification can potentially improve the detection performance primarily due to the air gap which reduced scatter by ∼20%. For both phantoms, at isodose, eDQE(0) for stereo∕BCI was ∼100 times higher than that for CXR. Magnification at isodose improved eDQE(0) by ∼10 times for stereo∕BCI. Increasing the dose did not improve eDQE. The detectability index for stereo∕BCI was ∼100 times better than single view CXR for all conditions. The detectability index was also not improved with increased dose. The findings indicate that stereo∕BCI with magnification may improve detectability of subtle lung nodules compared to single view CXR. Results were improved with magnification for the smaller phantom but not for the larger phantom. The effective DQE and the detectability index did not improve with increasing dose.

Although environmental enrichment has been shown to improve functional and histologic outcomes in pre-clinical moderate-to-severe traumatic brain injury (TBI), there are a paucity of pre-clinical data regarding enrichment strategies in the setting of repetitive mild traumatic brain injury (rmTBI). Given the vast numbers of athletes and those in the military who sustain rmTBI, the mounting evidence of the long-term and progressive sequelae of rmTBI, and the lack of targeted therapies to mitigate these sequelae, successful enrichment interventions in rmTBI could have large public health significance. Here, we evaluated enrichment strategies in an established pre-clinical rmTBI model. Seventy-one male C57BL/6 mice were randomized to two different housing conditions, environmental enrichment (EE) or normal condition (NC), then subjected to rmTBI injury (seven injuries in 9 days) or sham injury (anesthesia only). Functional outcomes in all four groups (NC-TBI, EE-TBI, NC-sham, and EE-sham) were assessed by motor, exploratory/anxiety, and mnemonic behavioral tests. At the synaptic level, N-methyl d-aspartate receptor (NMDAR) subunit expression of phosphorylated glutamate receptor 1 (GluR1), phosphorylated Ca 2+ /calmodulin-dependent protein kinase II (CaMKII), and calpain were evaluated by western blot. Compared to injured NC-TBI mice, EE-TBI mice had improved memory and decreased anxiety and exploratory activity post-injury. Treatment with enrichment also corresponded to normal NMDAR subunit expression, decreased GluR1 phosphorylation, decreased phosphorylated CaMKII, and normal calpain expression post-rmTBI. These data suggest that enrichment strategies may improve functional outcomes and mitigate synaptic changes post-rmTBI. Given that enrichment strategies are feasible in the clinical setting, particularly for athletes and soldiers for whom the risk of repetitive injury is greatest, these data suggest that clinical trials may be warranted.

To summarize the evidence on the health benefits of tai chi. A literature review was conducted on the benefits of tai chi for 25 specific conditions, as well as for general health and fitness, to update a 2014 review of systematic reviews. Systematic reviews and recent clinical trials were assessed and organized into 5 different groups: evidence of benefit as excellent, good, fair, or preliminary, or evidence of no direct benefit. During the past 45 years more than 500 trials and 120 systematic reviews have been published on the health benefits of tai chi. Systematic reviews of tai chi for specific conditions indicate excellent evidence of benefit for preventing falls, osteoarthritis, Parkinson disease, rehabilitation for chronic obstructive pulmonary disease, and improving cognitive capacity in older adults. There is good evidence of benefit for depression, cardiac and stroke rehabilitation, and dementia. There is fair evidence of benefit for improving quality of life for cancer patients, fibromyalgia, hypertension, and osteoporosis. Current evidence indicates no direct benefit for diabetes, rheumatoid arthritis, or chronic heart failure. Systematic reviews of general health and fitness benefits show excellent evidence of benefit for improving balance and aerobic capacity in those with poor fitness. There is good evidence for increased strength in the lower limbs. There is fair evidence for increased well-being and improved sleep. There were no studies that found tai chi worsened a condition. A recent systematic review on the safety of tai chi found adverse events were typically minor and primarily musculoskeletal; no intervention-related serious adverse events have been reported. There is abundant evidence on the health and fitness effects of tai chi. Based on this, physicians can now offer evidence-based recommendations to their patients, noting that tai chi is still an area of active research, and patients should continue to receive medical follow-up for any clinical conditions.

To assess the effect of armodafinil, 150 mg, on the physiologic propensity for sleep and cognitive performance during usual night shift hours in patients with excessive sleepiness associated with chronic (> or =3 months) shift work disorder (SWD) of moderate or greater severity. This 12-week, randomized controlled study was conducted at 42 sleep research facilities in North America from April 2 through December 23, 2004, and enrolled 254 permanent or rotating night shift workers with SWD. Entry criteria included excessive sleepiness during usual night shifts for 3 months or longer (corroborated by mean sleep latency of < or =6 minutes on a Multiple Sleep Latency Test), insomnia (sleep efficiency < or =87.5% during daytime sleep), and SWD that was judged clinically to be of moderate or greater severity. Patients received armodafinil, 150 mg, or placebo 30 to 60 minutes before each night shift. Physiologic sleep propensity during night shift hours, clinical impression of severity, patient-reported sleepiness, and cognitive function were assessed during laboratory night shifts at weeks 4, 8, and 12. Armodafinil significantly improved mean (SD) sleep latency from 2.3 (1.6) minutes at baseline to 5.3 (5.0) minutes at final visit, compared with a change from 2.4 (1.6) minutes to 2.8 (2.9) minutes in the placebo group (P<.001). Clinical condition ratings improved in more patients receiving armodafinil (79%) vs placebo (59%) (P=.001). As reported by patients' diaries, armodafinil significantly reduced sleepiness during laboratory nights (P<.001), night shifts at work (P<.001), and the commute home (P=.003). Armodafinil improved performance on standardized memory (P<.001) and attention (power, P=.001; continuity, P<.001) tests compared with placebo. Armodafinil was well tolerated and did not affect daytime sleep, as measured by polysomnography. In patients with excessive sleepiness associated with chronic SWD of moderate or greater severity, armodafinil significantly improved wakefulness during scheduled night work, raising mean nighttime sleep latency above the level considered to indicate severe sleepiness during the daytime. Armodafinil also significantly improved measures of overall clinical condition, long-term memory, and attention. clinicaltrials.gov Identifier: NCT00080288.

Only few studies have examined whether the efficacy of cognitive-behavioral therapy for childhood anxiety disorders as demonstrated in randomized controlled trials (RCTs) generalizes to clinical practice. This study examines the effectiveness of cognitive-behavioral therapy for juvenile anxiety disorders under routine care conditions in a university-based psychiatric outpatient clinic. 92 children and adolescents with parent-ratings regarding anxiety and comorbid symptoms and 61 children and adolescents with self-ratings regarding anxiety and comorbid symptoms were treated with cognitive-behavioral interventions. Pre/post mean comparisons, effect sizes, and the clinical significance of changes in symptoms were examined. The effect size for reduction of anxiety symptoms was .81 for children whose parents had completed the rating scale and .79 for children who had filled in a self-rating scale. Effect sizes for reduction of comorbid symptoms varied between .37 and .84 for parent ratings and between .21 and .62 for self-ratings. The percentage of children and adolescents who achieved clinically significant improvements in anxiety symptoms was 55.1 % according to the parent ratings and 65.7 % according to the children's self-ratings. More than 50 % of parents and children reported clinically significant improvements in comorbid symptoms. Significant reductions in both anxiety and comorbid symptoms were demonstrated over the course of cognitive-behavioral therapy of juvenile anxiety disorders in a university psychiatric outpatient clinic. The effect sizes for anxiety symptoms were found to be comparable to the effect sizes reported in RCTs. Similarly, clinically significant improvements were as frequent as the rates of remission of anxiety symptoms reported in RCTs.

Adaptive servo-ventilation (ASV) therapy is expected to be novel nonpharmacotherapy with hemodynamic effects on patients with chronic heart failure (CHF), but sufficient evidence has not been obtained. A 24-week, open-label, randomized, controlled study was performed to confirm the cardiac function-improving effect of ASV therapy on CHF patients. At 39 institutions, 213 outpatients with CHF, whose left ventricular ejection fraction (LVEF) was <40% and who had mild to severe symptoms [New York Heart Association (NYHA) class: ≥II], were enrolled. After excluding 8 patients, 102 and 103 underwent ASV plus guideline-directed medical therapy (GDMT) [ASV group] and GDMT only [control group], respectively. The primary endpoint was LVEF, and the secondary endpoints were HF deterioration, B-type natriuretic peptide (BNP), and clinical composite response (CCR: NYHA class+HF deterioration). LVEF and BNP improved significantly at completion against the baseline values in the 2 groups. However, no significant difference was found between these groups. HF deterioration tended to be suppressed. The ASV group showed a significant improvement in CCR corroborated by significant improvements in NYHA class and ADL against the control group. Under the present study's conditions, ASV therapy was not superior to GDMT in the cardiac function-improving effect but showed a clinical status-improving effect, thus indicating a given level of clinical benefit.

Evaluating the Effectiveness of an Online Cardiac Rehabilitation Resource (www.svhhearthealth.com.au) in Improving Knowledge and Confidence for Patients With Newly Diagnosed Cardiac Conditions: A Pre-Experimental Pilot Study.

Cardiac rehabilitation (CR) is an important tool for the secondary prevention of cardiac disease. Despite its proven effectiveness, CR remains vastly under-utilised especially amongst the most disadvantaged patients. As an adjunct to CR, the St Vincent's Heart Health website (SVHHH) was created by the St Vincent's Hospital CR team to provide information via simplified medical text, videos and animations. We evaluated the effectiveness of the website in educating patients about their heart condition. Patients with a newly diagnosed cardiac condition were recruited from St Vincent's Hospital inpatient wards and outpatient clinics (n=67, age 63+/-11) and given 30minutes to interact with our online resource. Using a pre-test post-test design we evaluated the success of the website in improving patients' knowledge of their condition using a modified Brief Illness Perception Questionnaire and Patient Activation Questionnaire. After interacting with the website, participants rated a 50% improvement in the control they felt over their heart condition (p<0.01). Understanding of investigations, medications and management improved by 38%, 31% and 38%, respectively (all p<0.01). Subjects' understanding of their heart condition improved by 34% and confidence improved by more than 18% (p<0.01). These improvements were seen irrespective of age and primary place of residence. While older subjects had the lowest confidence using the internet, they demonstrated the greatest self-reported improvement in knowledge. There was no improvement in patients' perceived concern about their illness. The St Vincent's Heart Health website shows real promise as an educational tool for patients, as an adjunct to standard CR and for patients in remote settings. Online health resources will likely become an important adjunct to traditional teaching methods across all medical specialties to improve patient outcomes.

In Electronic Health Records (EHRs), much of valuable information regarding patients’ conditions is embedded in free text format. Natural language processing (NLP) techniques have been developed to extract clinical information from free text. One challenge faced in clinical NLP is that the meaning of clinical entities is heavily affected by modifiers such as negation. A negation detection algorithm, NegEx, applies a simplistic approach that has been shown to be powerful in clinical NLP. However, due to the failure to consider the contextual relationship between words within a sentence, NegEx fails to correctly capture the negation status of concepts in complex sentences. Incorrect negation assignment could cause inaccurate diagnosis of patients’ condition or contaminated study cohorts. We developed a negation algorithm called DEEPEN to decrease NegEx’s false positives by taking into account the dependency relationship between negation words and concepts within a sentence using Stanford dependency parser. The system was developed and tested using EHR data from Indiana University (IU) and it was further evaluated on Mayo Clinic dataset to assess its generalizability. The evaluation results demonstrate DEEPEN, which incorporates dependency parsing into NegEx, can reduce the number of incorrect negation assignment for patients with positive findings, and therefore improve the identification of patients with the target clinical findings in EHRs.

The goal of comparative effectiveness research is to improve health care while dealing with the seemingly ever-rising cost. An understanding of comparative effectiveness research as a core topic is important for neuroradiologists. It can be used in a variety of ways. Its goal is to look at alternative methods of interacting with a clinical condition, ideally, while improving delivery of care. While the Patient-Centered Outcome Research initiative is the most mature US-based foray into comparative effectiveness research, it has been used more robustly in decision-making in other countries for quite some time. The National Institute for Health and Clinical Excellence of the United Kingdom is a noteworthy example of comparative effectiveness research in action. © 2014 by American Journal of Neuroradiology.

Newborns are a vulnerable population: Exposed to dramatically changing environmental conditions, potentially suffering from impairments that cannot realistically be diagnosed during pregnancy, with the risk that unfavorable conditions escalate fast. We have investigated informatics methods and tools to make screening for congenital diseases and containment of critical processes that start in the first days safer and more efficient. This poster present a set of three different methodological approaches that all aim at comprehensive improvement of neonatal care.

Purpose To describe the clinical characteristics, treatment, and subsequent clinical course of children with exotropia and high hyperopia. Methods The medical records of 26 patients seen between 1990 and 2009 who had an exotropia and ≥4.00 D of hyperopia were retrospectively reviewed. We analyzed the clinical characteristics, treatments and subsequent alignment outcomes. Results A total of 26 patients between the ages of 2.5 months and 9 years were included. Of these, 15 had associated medical conditions or developmental delay. Of 22 patients with measured visual acuities, 19 had amblyopia (10 unilateral, 9 bilateral). None of the patients demonstrated fine stereoacuity. Twenty-three exotropic children were treated with spectacles; 15 were fully corrected, 10 of whose exotropia improved; 8 received partial correction of their hyperopia, 3 of whose exotropia improved. Six patients who presented with large, poorly controlled exotropia and did not improve with spectacle correction required strabismus surgery. Conclusions Children with high hyperopia and exotropia are likely to have developmental delay or other systemic diseases, amblyopia, and poor stereopsis. Treatment of high hyperopia in exotropic children with their full cycloplegic refraction can result in excellent alignment. PMID:23084380

A robust quality-assurance program is essential for laboratories that perform molecular genetic testing to maintain high-quality testing and be able to address challenges associated with performance or delivery of testing services as the use of molecular genetic tests continues to expand in clinical and public health practice. This unit discusses quality-assurance and quality-improvement considerations that are critical for molecular genetic testing performed for heritable diseases and conditions. Specific discussion is provided on applying regulatory standards and best practices in establishing/verifying test performance, ensuring quality of the total testing process, monitoring and maintaining personnel competency, and continuing quality improvement. The unit provides a practical reference for laboratory professionals to use in recognizing and addressing essential quality-assurance issues in human molecular genetic testing. It should also provide useful information for genetics researchers, trainees, and fellows in human genetics training programs, as well as others who are interested in quality assurance and quality improvement for molecular genetic testing. 2011 by John Wiley & Sons, Inc.

To assess validity of adjuvant use of pumpan, a homeopathic compound, in patients with unstable angina pectoris and angina of effort (functional class III-IV) receiving conventional treatment. A direct open controlled trial for 15 months performed initially in hospital, then outpatiently, covered 49 patients with severe angina. Examination of the patients included evaluation of clinical condition and the disease course, lipid metabolism, hemostasis, blood plasma electrolytes, aminotransferases, echo-CG, bicycle exercise, rheoencephalography, ultrasonic dopplerography of head and neck vessels. Pumpan produced a positive effect total nonspecific systemic resistance improved, number of hospitalizations reduced, intracardiac hemodynamics improved in some cases with severe angina. Homeopathic compound pumpan can be recommended in the treatment of severe angina to reinforce antianginal effect, improve the disease clinical course, to obtain a hypocoagulative and hypocholesterolemic effect, to normalize intracardiac hemodynamics, to raise myocardial performance and intracoronary reserve as well as nonspecific resistance of the body.

Do resettlement variables predict psychiatric treatment outcomes in a sample of asylum-seeking survivors of torture?

PubMed

Whitsett, David; Sherman, Martin F

2017-12-01

Mental health clinicians who work with asylum seekers provide services to patients who face stressful everyday living conditions. However, little is known about how these problems potentially impact psychiatric treatment within these populations. The purpose of this study was thus to examine whether resettlement factors predict outcomes of a mental health intervention for a sample of asylum-seeking survivors of torture. The study included data from a US outpatient clinic that specialized in treating asylum-seeking survivors of torture. Patients (primarily from Iraq, Afghanistan and African Countries) were evaluated on demographic factors at intake and psychiatric symptoms throughout the course of treatment. Patients experienced significant reductions in depression, anxiety and trauma symptoms, although symptoms still remained near or above clinical thresholds. Stable, uncrowded housing conditions significantly predicted lower depression, anxiety and trauma symptoms at follow-up. These findings support the hypotheses that individuals seeking asylum within the United States who have survived torture can benefit from psychiatric treatment and emphasize the importance of stable living conditions in improving treatment effectiveness. This suggests the need for further research on social predictors of treatment outcomes, as well as the need for clinicians and policymakers to target improved housing as a potentially important tool to reduce psychiatric problems related to torture and forced migration.

Spine Conditions: Mechanical and Inflammatory Low Back Pain.

PubMed

Ledford, Christopher

2017-10-01

Mechanical low back pain (LBP) is an injury or derangement of an anatomic structure in the low back. When evaluating patients with LBP, clinicians should maintain clinical suspicion for vertebral fracture, cancer, and cauda equina syndrome. Management includes patient education focused on exercise, massage, and behavioral approaches such as cognitive behavioral therapy. Acupuncture can be an effective alternative and specific herbal supplements may provide short-term pain relief. The prognosis for patients with mechanical LBP is good. Inflammatory LBP is pain resulting from a systemic inflammatory condition, often referred to as axial spondyloarthritis. Ankylosing spondylitis is chronic inflammatory LBP characterized by early onset (mean age 24 years), with a higher prevalence in men. Five clinical parameters can help identify inflammatory LBP: improvement with exercise, pain at night, insidious onset, onset at younger than 40 years, and no improvement with rest. Management of inflammatory LBP typically includes nonsteroidal anti-inflammatory drugs and structured exercise programs, with emphasis on the involvement of a rheumatology subspecialist. Spondyloarthritis is associated with other rheumatic or autoimmune conditions, including rheumatoid arthritis, inflammatory bowel disease, and psoriasis. These should be considered when evaluating patients with inflammatory LBP.

A 55 years old man self-presented to our Emergency Department (ED) reporting an attempted suicide by cutting the left forearm veins and ingesting approximately 200 mL of an herbicide (Myrtos®, containing 36% of glyphosate as isopropylamine salt). Laboratory tests showed metabolic acidosis. Hydration with normal saline and alkalinization with sodium bicarbonate was started according to suggestion of the poison control center, since an antidote was unavailable. Cardiorespiratory condition gradually worsened, so that non-invasive positive pressure ventilation (NIPPV) was applied and infusion of fluids was established. Nevertheless, the patient deteriorated and he needed to be transferred to the Intensive Care Unit (ICU), where he underwent orotracheal intubation and invasive mechanical ventilation. Noradrenaline and adrenaline were infused and fluid resuscitation with crystalloids was incremented. An esophagogastroduodenoscopy (EGD) showed diffuse mucosal erosions of upper digestive tract. No signs of visceral perforation were found during ICU stay. In the following days, the clinical conditions improved and a new EGD showed marked improvement of erosive lesions. After 12 days of ICU stay, the patient was extubated and then transferred to the Psychiatric Unit, in good clinical conditions. Gliphosate ingestion is associated with rapid development of multiple organ failure (MOF). Since an effective antidote is unavailable, major attention should be placed to aggressive life-support care and careful monitoring of complications.

Insomnia is a common clinical complaint, and if not addressed it can increase the risk of developing other underlying diseases such as hypertension, depression and anxiety. The use of Mongolian mind-body interactive therapy as a comprehensive psychotherapeutic approach in chronic insomnia has been shown in this retrospective study. Subjects who had suffered insomnia for more than 1 month participated in the Mongolian mind-body interactive psychotherapy program between June 2012 and February 2014. They were interviewed by telephone at least 10 months before participating in the program. Their sleep was assessed using the Athens insomnia scale. Descriptive statistics, ANOVA and regression analysis were used for data analysis by SPSS software. Mongolian mind-body interactive psychotherapy significantly improved sleeping conditions. In ANOVA analysis, both short- and long-term outcomes were significantly affected by the treatment period. Patients who previously took medication and pre-treatment sleeping condition (ASI score) had a significant influence on long-term outcomes, as well as treatment time related to the duration of insomnia. Mongolian mind-body interactive psychotherapy is a new method for insomnia, and narrative therapy and hypnotic methods together improve the sleeping condition, However, a further controlled randomized clinical study is needed to understand the efficacy.

The Chronic Care Model as vehicle for the development of disease management in Europe

PubMed Central

Spreeuwenberg, Cor

2008-01-01

The Chronic Care Model (Wagner, WHO) aims to improve the functioning and clinical situation of chronic patients by focussing on the patient, the practice team and the conditions that determine the functioning of the team. The patient is the most important actor who must be stimulated proactively by a competent, integrated practice team. Six interdependent conditional components are essential: health care organisation, delivery system design, community resources and policies, self-management support systems, decision support and clinical information systems. While the Chronic Care Model focuses on quality and effectiveness of care, disease management programmes underline more the efficiency of care. These programmes apply industrial management principles in health care. Information about process, structure and outcome is gathered and used systematically and human and material sources are used efficiently. There is evidence that the approaches of the Chronic Care Model and disease management can be integrated. Both approaches underline the need of information and focus on the patient as the main actor to improve and that a balance can be found between effectiveness and efficiency. Ideas will be given how the Chronic Care Model can be used as a framework for the development of a European way of disease management for people with a chronic condition.

There are differences in the educational context in Health Sciences, between clinical and non-clinical teachers. Therefore, the didactic and reflexive peculiarities of both educational scenarios should be analyzed. To describe the conditions of the educational context in Health Sciences for the practice of the teaching role in a Chilean university. Qualitative study, performed according to Grounded Theory of Strauss and Corbin. Thirty one teachers from six health sciences programs were selected according to Patton's maximum variation criterion and contacted personally, after an informed consent process. Semi-structured interviews and focus group were performed, analyzed by open coding, using the constant comparison method, with the Atlas-ti 7.5.2 software. Six conditions of the educational context that can support the teaching role in these careers emerged. Namely, a clinical field suited for patient attention and teaching, classrooms designed for the new educational models, number of students in the classrooms and clinical settings, insertion programs for teachers' training, teachers' coordination and economic resources of the program. Health Sciences programs are developed in a complex educational context, having to articulate diverse elements to train professionals. Therefore, it is fundamental to understand the conditions of the educational context that can favor the practice of the teaching role, thus generating improvements in teaching-learning process.

The impact of patient support programs on adherence, clinical, humanistic, and economic patient outcomes: a targeted systematic review

Background Patient support programs (PSPs), including medication management and counseling, have the potential to improve care in chronic disease states with complex therapies. Little is known about the program’s effects on improving clinical, adherence, humanistic, and cost outcomes. Purpose To conduct a targeted review describing medical conditions in which PSPs have been implemented; support delivery components (eg, face-to-face, phone, mail, and internet); and outcomes associated with implementation. Data sources MEDLINE – 10 years through March 2015 with supplemental handsearching of reference lists. Study selection English-language trials and observational studies of PSPs providing at minimum, counseling for medication management, measurement of ≥1 clinical outcome, and a 3-month follow-up period during which outcomes were measured. Data extraction Program characteristics and related clinical, adherence, humanistic, and cost outcomes were abstracted. Study quality and the overall strength of evidence were reviewed using standard criteria. Data synthesis Of 2,239 citations, 64 studies met inclusion criteria. All targeted chronic disease processes and the majority (48 [75%]) of programs offered in-clinic, face-to-face support. All but 9 (14.1%) were overseen by allied health care professionals (eg, nurses, pharmacists, paraprofessionals). Forty-one (64.1%) reported at least one significantly positive clinical outcome. The most frequent clinical outcome impacted was adherence, where 27 of 41 (66%) reported a positive outcome. Of 42 studies measuring humanistic outcomes (eg, quality of life, functional status), 27 (64%) reported significantly positive outcomes. Only 15 (23.4%) programs reported cost or utilization-related outcomes, and, of these, 12 reported positive impacts. Conclusion The preponderance of evidence suggests a positive impact of PSPs on adherence, clinical and humanistic outcomes. Although less often measured, health care utilization and costs are also reduced following PSP implementation. Further research is needed to better quantify which support programs, delivery methods, and components offer the greatest value for any particular medical condition. PMID:27175071

This randomized clinical trial examined the efficacy of comprehensive Usual Care (UC) alone (n=42) or enhanced by Reinforcement-Based Treatment (RBT) (n=47) to produce improved treatment outcomes, maternal delivery, and neonatal outcomes in pregnant women with opioid and/or cocaine substance use disorders. RBT participants spent, on average, 32.6 days longer in treatment (p<.001) and almost six times longer in recovery housing than did UC participants (p=.01). There were no significant differences between the RBT and UC conditions in proportion of participants testing positive for any illegal substance. Neonates in the RBT condition spent 1.3 fewer days hospitalized after birth than UC condition neonates (p=.03), although the two conditions did not differ significantly in neonatal gestational age at delivery, birth weight, or number of days hospitalized. Integrating RBT into a rich array of comprehensive care treatment components may be a promising approach to increase maternal treatment retention and reduce neonatal length of hospital stay.

Atherosclerotic renovascular disease – epidemiology, treatment and current challenges

Vassallo, Diana

2017-01-01

The neutral results of recent large randomized controlled trials comparing renal revascularization with optimal medical therapy in patients with atherosclerotic renovascular disease (ARVD) have cast doubt on the role of revascularization in the management of unselected patients with this condition. However, these studies have strengthened the evidence base for the role of contemporary intensive medical vascular protection therapy and aggressive risk factor control in improving clinical outcomes in ARVD. Patients presenting with ‘high-risk’ clinical features such as uncontrolled hypertension, rapidly declining renal function or flash pulmonary oedema are underrepresented in these studies; hence these results may not be applicable to all patients with ARVD. In this ‘high-risk’ subgroup, conservative management may not be sufficient in preventing adverse events, and indeed, observational evidence suggests that this specific patient subgroup may gain benefit from timely renal revascularization. Current challenges include the development of novel diagnostic techniques to establish haemodynamic significance of a stenosis, patient risk stratification and prediction of post-revascularization outcomes to ultimately facilitate patient selection for revascularization. In this paper we describe the epidemiology of this condition and discuss treatment recommendations for this condition in light of the results of recent randomized controlled trials while highlighting important clinical unmet needs and challenges faced by clinicians managing this condition.

A varying-coefficient method for analyzing longitudinal clinical trials data with nonignorable dropout

PubMed Central

Forster, Jeri E.; MaWhinney, Samantha; Ball, Erika L.; Fairclough, Diane

2011-01-01

Dropout is common in longitudinal clinical trials and when the probability of dropout depends on unobserved outcomes even after conditioning on available data, it is considered missing not at random and therefore nonignorable. To address this problem, mixture models can be used to account for the relationship between a longitudinal outcome and dropout. We propose a Natural Spline Varying-coefficient mixture model (NSV), which is a straightforward extension of the parametric Conditional Linear Model (CLM). We assume that the outcome follows a varying-coefficient model conditional on a continuous dropout distribution. Natural cubic B-splines are used to allow the regression coefficients to semiparametrically depend on dropout and inference is therefore more robust. Additionally, this method is computationally stable and relatively simple to implement. We conduct simulation studies to evaluate performance and compare methodologies in settings where the longitudinal trajectories are linear and dropout time is observed for all individuals. Performance is assessed under conditions where model assumptions are both met and violated. In addition, we compare the NSV to the CLM and a standard random-effects model using an HIV/AIDS clinical trial with probable nonignorable dropout. The simulation studies suggest that the NSV is an improvement over the CLM when dropout has a nonlinear dependence on the outcome. PMID:22101223

The ability to predict outcome after shunt placement in patients with idiopathic normal-pressure hydrocephalus (NPH) represents a challenge. To date, no single diagnostic tool or combination of tools has proved capable of reliably predicting whether the condition of a patient with suspected NPH will improve after a shunting procedure. In this paper, the authors report their experience with 120 patients with the goal of identifying CSF hydrodynamics criteria capable of selecting patients with idiopathic NPH. Specifically, they focused on the comparison between CSF-outflow resistance (R-out) and intracranial elastance (IE). Between January 1977 and December 2005, 120 patients in whom idiopathic NPH had been diagnosed (on the basis of clinical findings and imaging) underwent CSF hydrodynamics evaluation based on an intraventricular infusion test. Ninety-six patients underwent CSF shunt placement: 32 between 1977 and 1989 (Group I) on the basis of purely clinical and radiological criteria; 44 between 1990 and 2002 (Group II) on the basis of the same criteria as Group I and because they had an IE slope > 0.25; and 20 between 2003 and 2005 (Group III) on the basis of the same criteria as Group II but with an IE slope > or = 0.30. Outcomes were evaluated by means of both Stein-Langfitt and Larsson scores. Patients' conditions were considered improved when there was a stable decrease (at 6- and 12-month follow-up) of at least 1 point in the Stein-Langfitt score and 2 points in the Larsson score. Group I: while no statistically significant difference in mean R-out value between improved and unimproved cases was observed, a clear-cut IE slope value of 0.25 differentiated very sharply between unimproved and improved cases. Group II: R-out values in the 2 unimproved cases were 20 and 47 mm Hg/ml/min, respectively. The mean IE slope in the improved cases was 0.56 (range 0.30-1.4), while the IE slopes in the 2 unimproved cases were 0.26 and 0.27. Group III: the mean IE slope was 0.51 (range 0.31-0.7). The conditions of all patients improved after shunting. A significant reduction of the Evans ratio was observed in 34 (40.5%) of the 84 improved cases and in none of the unimproved cases. Our strategy based on the analysis of CSF pulse pressure parameters seems to have a great accuracy in predicting surgical outcome in clinical practice.

2012-01-01

Deep brain stimulation (DBS) of the subthalamic nucleus improves the motor symptoms of Parkinson's disease, but may produce a worsening of speech and language performance at rates and amplitudes typically selected in clinical practice. The possibility that these dissociated effects might be modulated by selective stimulation of left and right STN has never been systematically investigated. To address this issue, we analyzed motor, speech and language functions of 12 patients implanted with bilateral stimulators configured for optimal motor responses. Behavioral responses were quantified under four stimulator conditions: bilateral DBS, right-only DBS, left-only DBS and no DBS. Under bilateral and left-only DBS conditions, our results exhibited a significant improvement in motor symptoms but worsening of speech and language. These findings contribute to the growing body of literature demonstrating that bilateral STN DBS compromises speech and language function and suggests that these negative effects may be principally due to left-sided stimulation. These findings may have practical clinical consequences, suggesting that clinicians might optimize motor, speech and language functions by carefully adjusting left- and right-sided stimulation parameters.

A Rare Presentation of Cyclitis Induced Myopia.

2018-03-01

Unilateral cyclitis leading to myopia is a rare and clinical relevant entity. In clinical settings, pseudomyopia is generally encountered in the form of accommodative spasm, which is always bilateral. Cyclitis due to inflammation, on the other hand, can cause pseudomyopia unilaterally and it is a very rare presentation. A young male with acute anterior uveitis, presented with acute episode of unilateral myopia. When patient was examined on first visit, there were no cells in anterior chamber; so he was started on cycloplegic eye drops, but his condition didn't improve. Examination on subsequent visit revealed cellular reaction in anterior chamber and narrowing of anterior chamber angles on anterior segment optical coherence tomography (OCT). Treatment for uveitis was started and patient's visual acuity and refractive error improved. Pseudomyopia is a known complication of several drugs and certain medical conditions. The possible mechanism is supraciliary exudation causing relaxation of zonular fibers and increased convexity of the crystalline lens. Myopia in the setting of a mild cellular reaction can easily be missed and has not been reported yet to the best of authors' literature search.

Objective long-term health monitoring can improve the clinical management of several medical conditions ranging from cardiopulmonary diseases to motor disorders. In this paper, we present our work toward the development of a home-monitoring system. The system is currently used to monitor patients with Parkinson's disease who experience severe motor fluctuations. Monitoring is achieved using wireless wearable sensors whose data are relayed to a remote clinical site via a web-based application. The work herein presented shows that wearable sensors combined with a web-based application provide reliable quantitative information that can be used for clinical decision making.

2017-08-01

This article describes results from a randomized clinical trial of a mindfulness-based intervention for parents and children, Mindful Family Stress Reduction, on a behavioral measure of attention in youths, the Attention Network Task (ANT). Forty-one parent-child dyads were randomly assigned to either the mindfulness-based intervention condition or a wait-list control. School-age youths completed the ANT before and after the intervention. Results demonstrate significant, medium-size ( f 2 = -.16) intervention effects to the conflict monitoring subsystem of the ANT such that those in the intervention condition decreased in conflict monitoring more than those in the wait-list control. Youths in the intervention condition also showed improvements in their orienting subsystem scores, compared with controls. Mindfulness-based interventions for youths have potential utility to improve attentional self-regulation, and future research should consider incorporating measures of attention into interventions that use mindfulness training.

Cognitive remediation in anorexia nervosa and related conditions: a systematic review.

2014-11-01

Research evidence for cognitive remediation therapy's (CRT) effectiveness for anorexia nervosa (AN) has been gathering. This approach is also increasingly being implemented in other disorders including major depressive disorder, obsessive-compulsive disorder and autistic spectrum disorder that share commonalities with AN in neuropsychological profiles and clinical presentations. This systematic literature review identified and appraised the current evidence base to see whether evidence from related conditions could be integrated into the theoretical understanding of CRT for AN as well as future AN treatment developments and research. Overall, CRT studies in AN report promising findings, and CRT appears to be associated with improvements in set-shifting and in central coherence. Cognitive remediation approaches in other conditions also show promising evidence in associated improvements in areas of executive functioning and information processing; links are made between AN treatment and what future treatment developments could consider.

Respiratory failure complicating the course of diabetic ketoacidosis (DKA) is a source of increased morbidity and mortality. Detection of respiratory failure in DKA requires focused clinical monitoring, careful interpretation of arterial blood gases, and investigation for conditions that can affect adversely the respiration. Conditions that compromise respiratory function caused by DKA can be detected at presentation but are usually more prevalent during treatment. These conditions include deficits of potassium, magnesium and phosphate and hydrostatic or non-hydrostatic pulmonary edema. Conditions not caused by DKA that can worsen respiratory function under the added stress of DKA include infections of the respiratory system, pre-existing respiratory or neuromuscular disease and miscellaneous other conditions. Prompt recognition and management of the conditions that can lead to respiratory failure in DKA may prevent respiratory failure and improve mortality from DKA.

However, the effect of ingested HA may depend on its molecular weight (MW) because its physiological activities in the body vary with its MW. In this study, we examined the effects of ingested HA with varying MW on the skin. In this randomized, double blind, placebo controlled study, 61 subjects with dry skin received oral HA (120 mg/day), of MWs 800 k and 300 k or placebo, for 6 weeks. The skin moisture contents of the first two groups increased more than those of the placebo group during the ingestion period. In addition, group HA 300 k exhibited significant improvements in skin moisture content 2 weeks after ingestion ended compared with the placebo group. A questionnaire survey about subjective facial aging symptoms showed that the HA treated groups exhibited significantly improved the skin condition compared with the placebo treated group. Furthermore, dermatologists objectively evaluated the clinical symptoms of the facial and whole body skin, showing that no adverse events were related to daily ingestion of HA. This study shows that both of ingesting HAs (MWs 800 k and 300 k) improved the skin condition by increasing the moisture content.

Asthma represents a profound world-wide public health problem. The most effective anti-asthmatic drugs currently available include β2-agonists and glucocorticoids which can controls asthma in about 90-95% of patients. In Ayurveda, this miserable condition is comparable with Tamaka Shwasa type of Shwasa Roga. In the present study, 52 patients were treated with Sameera Pannaga Rasa at a dose of 30 mg twice a day for 4 weeks along with Nagavallidala (leaf of Piper betel Linn.) The results were assessed in terms of clinical recovery, symptomatic relief, pulmonary function improvement and on subjective and objective parameters. A significant improvement in subjective parameters, control on asthma, recurrence of asthma, increase in peak expiratory flow rate, considerable decrease in total and absolute, acute eosinophil count and erythrocyte sedimentation rate were observed. Overall marked improvement was found in 33.33%, moderate improvement in 44.44% and mild improvement in 20.00% was observed. The study reveals that Sameera Pannaga Rasa can be used as an effective drug in bronchial asthma. PMID:24696570

The background of this research is to study morphological and functional microcirculatory channel condition with duodenum ulcer in the period of rehabilitation against the background of regular antiulcer therapy (1 group) and further treatment using Vazonit (2 group) in clinical conditions. EDU in animals results in marked microcirculatory disease in duodenum depending on the time of ulcer process development. Hypoxia is to be the significant factor associated with capillary stases, venous congestion. Blood flow impairment in organ results in metabolic damages of tissue structures. The results obtained are evidence of significant correction of microcirculatory channel state, improvement of regeneration and reparation processes. Vazonit improves the disorder of microcirculation and theological blood properties, restoring of macro and microangiopathy changes of hemocirculatory channel.

Reprogramming human adult blood mononuclear cells (MNCs) cells by transient plasmid expression is becoming increasingly popular as an attractive method for generating induced pluripotent stem (iPS) cells without the genomic alteration caused by genome-inserting vectors. However, its efficiency is relatively low with adult MNCs compared with cord blood MNCs and other fetal cells and is highly variable among different adult individuals. We report highly efficient iPS cell derivation under clinically compliant conditions via three major improvements. First, we revised a combination of three EBNA1/OriP episomal vectors expressing five transgenes, which increased reprogramming efficiency by ≥10–50-fold from our previous vectors. Second, human recombinant vitronectin proteins were used as cell culture substrates, alleviating the need for feeder cells or animal-sourced proteins. Finally, we eliminated the previously critical step of manually picking individual iPS cell clones by pooling newly emerged iPS cell colonies. Pooled cultures were then purified based on the presence of the TRA-1-60 pluripotency surface antigen, resulting in the ability to rapidly expand iPS cells for subsequent applications. These new improvements permit a consistent and reliable method to generate human iPS cells with minimal clonal variations from blood MNCs, including previously difficult samples such as those from patients with paroxysmal nocturnal hemoglobinuria. In addition, this method of efficiently generating iPS cells under feeder-free and xeno-free conditions allows for the establishment of clinically compliant iPS cell lines for future therapeutic applications.

According to most relevant guidelines, family psycho-educational interventions are considered to be one the most effective psychosocial treatments for people with schizophrenia. The main outcome measure in controlled and randomized studies has been prevention of relapses and admissions, and encouragement of compliance, although some questions remain about its applicability and results in clinical practice. The aim of study was to evaluate the efficacy and implementation of a single family psychoeducational intervention in 'real' conditions for people diagnosed with schizophrenia. A total of 88 families were randomized in two groups. The family intervention group received a 12 months psychoeducational treatment, and the other group followed normal standard treatment. Assessments were made at baseline, at 12 and at 18 months. The main outcome measure was hospitalization, and secondary outcome measures were clinical condition (BPRS-E) and social disability (DAS-II). A total of 71 patients finished the study (34 family intervention group and 37 control group). Patients who received family intervention reduced the risk of hospitalization by 40% (P = .4018; 95%CI: 0.1833-0.6204). Symptomatology improved significantly at 12 months (P = .4018; 95%CI: 0.1833-0.6204), but not at 18 months (P = .4018; 95%CI: 0.1833-0.6204). Social disability was significantly reduced in the family intervention group at 12 months and 18 months. Family psychoeducational intervention reduces hospitalization risk and improves clinical condition and social functioning of people with schizophrenia. Copyright © 2013 SEP y SEPB.

A clinical database is a repository of patient medical and sociodemographic information focused on one or more specific health condition or exposure. Although clinical databases may be used for research purposes, their primary goal is to collect and track patient data for quality improvement, quality assurance, and/or actual clinical management. This article aims to provide an introduction and practical advice on the development of small-scale clinical databases for chest physicians and practice groups. Through example projects, we discuss the pros and cons of available technical platforms, including Microsoft Excel and Access, relational database management systems such as Oracle and PostgreSQL, and Research Electronic Data Capture. We consider approaches to deciding the base unit of data collection, creating consensus around variable definitions, and structuring routine clinical care to complement database aims. We conclude with an overview of regulatory and security considerations for clinical databases. Copyright © 2018 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

Improvements in Orientation and Balancing Abilities in Response to One Month of Intensive Slackline-Training. A Randomized Controlled Feasibility Study.

PubMed

Dordevic, Milos; Hökelmann, Anita; Müller, Patrick; Rehfeld, Kathrin; Müller, Notger G

2017-01-01

Background: Slackline-training has been shown to improve mainly task-specific balancing skills. Non-task specific effects were assessed for tandem stance and preferred one-leg stance on stable and perturbed force platforms with open eyes. It is unclear whether transfer effects exist for other balancing conditions and which component of the balancing ability is affected. Also, it is not known whether slackline-training can improve non-visual-dependent spatial orientation abilities, a function mainly supported by the hippocampus. Objective: To assess the effect of one-month of slackline-training on different components of balancing ability and its transfer effects on non-visual-dependent spatial orientation abilities. Materials and Methods: Fifty subjects aged 18-30 were randomly assigned to the training group (T) ( n = 25, 23.2 ± 2.5 years; 12 females) and the control group (C) ( n = 25, 24.4 ± 2.8 years; 11 females). Professional instructors taught the intervention group to slackline over four consecutive weeks with three 60-min-trainings in each week. Data acquisition was performed (within 2 days) by blinded investigators at the baseline and after the training. Main outcomes Improvement in the score of a 30-item clinical balance test (CBT) developed at our institute (max. score = 90 points) and in the average error distance (in centimeters) in an orientation test (OT), a triangle completion task with walking and wheelchair conditions for 60°, 90°, and 120°. Results: Training group performed significantly better on the closed-eyes conditions of the CBT (1.6 points, 95% CI: 0.6 to 2.6 points vs. 0.1 points, 95% CI: -1 to 1.1 points; p = 0.011, [Formula: see text] = 0.128) and in the wheelchair (vestibular) condition of the OT (21 cm, 95% CI: 8-34 cm vs. 1 cm, 95% CI: -14-16 cm; p = 0.049, [Formula: see text] = 0.013). Conclusion: Our results indicate that one month of intensive slackline training is a novel approach for enhancing clinically relevant balancing abilities in conditions with closed eyes as well as for improving the vestibular-dependent spatial orientation capability; both of the benefits are likely caused by positive influence of slackline-training on the vestibular system function.

Objectives/Hypotheses The objective was to assess the utility of selected “resonant voice” exercises for the reduction of acute vocal fold inflammation. The hypothesis was that relatively large-amplitude, low-impact exercises associated with resonant voice would reduce inflammation more than spontaneous speech and possibly more than voice rest. Study Design The study design was prospective, randomized, double-blind. Methods Nine vocally healthy adults underwent a 1-hr vocal loading procedure, followed by randomization to (a) a spontaneous speech condition, (b) a vocal rest condition, or (c) a resonant voice exercise condition. Treatments were monitored in clinic for 4 hr, and continued extra-clinically until the next morning. At baseline, immediately following loading, after the 4-hr in-clinic treatment, and 24 hr post baseline, secretions were suctioned from the vocal folds bilaterally and submitted to enzyme-linked immunosorbent assay (ELISA) to estimate concentrations of key markers of tissue injury and inflammation: IL-1β, IL-6, IL-8, TNF-α, MMP-8, and IL-10. Results Complete data sets were obtained for 3 markers -- IL-1β, IL-6, and MMP-8 -- for one subject in each treatment condition. For those markers, results were poorest at 24-hr follow-up in the spontaneous speech condition, sharply improved in the voice rest condition, and best in the resonant voice condition. Average results for all markers, for all responsive subjects with normal baseline mediator concentrations, revealed an almost identical pattern. Conclusions Some forms of tissue mobilization may be useful to attenuate acute vocal fold inflammation. PMID:23177745

Marketing depression care management to employers: design of a randomized controlled trial

PubMed Central

2010-01-01

Background Randomized trials demonstrate that depression care management can improve clinical and work outcomes sufficiently for selected employers to realize a return on investment. Employers can now purchase depression products that provide depression care management, defined as employee screening, education, monitoring, and clinician feedback for all depressed employees. We developed an intervention to encourage employers to purchase a depression product that offers the type, intensity, and duration of care management shown to improve clinical and work outcomes. Methods In a randomized controlled trial conducted with 360 employers of 30 regional business coalitions, the research team proposes to compare the impact of a value-based marketing intervention to usual-care marketing on employer purchase of depression products. The study will also identify mediators and organizational-level moderators of intervention impact. Employers randomized to the value-based condition receive a presentation encouraging them to purchase depression products scientifically shown to benefit the employee and the employer. Employers randomized to the usual-care condition receive a presentation encouraging them to monitor and improve quality indicators for outpatient depression treatment. Because previous research demonstrates that the usual-care intervention will have little to no impact on employer purchasing, depression product purchasing rates in the usual-care condition capture vendor efforts to market depression products to employers in both conditions while the value-based intervention is being conducted. Employers in both conditions are also provided free technical assistance to undertake the actions each presentation encourages. The research team will use intent-to-treat models of all available data to evaluate intervention impact on the purchase of depression products using a cumulative incidence analysis of 12- and 24-month data. Discussion By addressing the 'value to whom?' question, the study advances knowledge about one of the most pivotal problems in the translation of evidence-based care to 'real world' settings: whether purchasers can be influenced to buy healthcare products on the basis of value and not exclusively on the basis of cost. If value-based marketing increases depression product purchase rates over usual care, this study will provide encouragement to market new healthcare products on the basis of the product's value to the purchaser as well as the recipient of care.

The variables that influence the extent to which patients and their families remember and follow neuropsychological recommendations after their appointments are unclear. There has been limited research on this topic. The current study was designed to address this knowledge gap. Patients (n = 79) and caregivers (n = 36) were randomized into 1 of 2 groups, letter or no-letter, to investigate whether providing a supplemental written reminder of the recommendations given (in addition to routine feedback procedures in our clinic) would improve memory for and adherence to recommendations. We found that recall of recommendations was better in the letter condition, although this effect was observed in the caregivers and not in the patients. Adherence to recommendations did not differ significantly between the letter and no-letter conditions. These findings show that a simple intervention can improve caregiver memory for recommendations. Future research could help determine how to translate improvements in memory into greater adherence.

Adherence to prescribed medications is associated with improved clinical outcomes for chronic disease management and reduced mortality from chronic conditions (1). Conversely, nonadherence is associated with higher rates of hospital admissions, suboptimal health outcomes, increased morbidity and mortality, and increased health care costs (2). In the United States, 3.8 billion prescriptions are written annually (3). Approximately one in five new prescriptions are never filled, and among those filled, approximately 50% are taken incorrectly, particularly with regard to timing, dosage, frequency, and duration (4). Whereas rates of nonadherence across the United States have remained relatively stable, direct health care costs associated with nonadherence have grown to approximately $100-$300 billion of U.S. health care dollars spent annually (5,6). Improving medication adherence is a public health priority and could reduce the economic and health burdens of many diseases and chronic conditions (7).

A review of the critical role of vitamin D in the functioning of the immune system and the clinical implications of vitamin D deficiency.

This review looks at the critical role of vitamin D in improving barrier function, production of antimicrobial peptides including cathelicidin and some defensins, and immune modulation. The function of vitamin D in the innate immune system and in the epithelial cells of the oral cavity, lung, gastrointestinal system, genito-urinary system, skin and surface of the eye is discussed. Clinical conditions are reviewed where vitamin D may play a role in the prevention of infections or where it may be used as primary or adjuvant treatment for viral, bacterial and fungal infections. Several conditions such as tuberculosis, psoriasis, eczema, Crohn's disease, chest infections, wound infections, influenza, urinary tract infections, eye infections and wound healing may benefit from adequate circulating 25(OH)D as substrate. Clinical diseases are presented in which optimization of 25(OH)D levels may benefit or cause harm according to present day knowledge. The safety of using larger doses of vitamin D in various clinical settings is discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Eosinophilic esophagitis (EoE) is a clinicopathologic condition characterized by symptoms of esophageal dysfunction in the presence of eosinophil-predominant inflammation of esophageal mucosa. Topical steroids are recommended as first line pharmacologic therapy in EoE. We aimed to determine the efficacy of topical steroids in inducing histologic and clinical remission in children and adults with EoE. We performed a systematic search of the MEDLINE, EMBASE, Scopus, and Cochrane library databases for studies investigating the efficacy of topical steroids in EoE. We collected data on the number of patients, dose and duration of therapy, complete and partial histological response, and clinical improvement. We performed meta-analysis of placebo-controlled randomized clinical trials using Review Manager version 5.2. We used funnel plots to evaluate for publication bias. Five studies that included 174 patients with EoE were included in the meta-analysis. Topical fluticasone was administered in three studies involving 114 patients, and topical budesonide in two studies involving 60 patients. Patients treated with topical steroids, as compared with placebo, had higher complete histological remission (odds ratio [OR] 20.81, 95% confidence interval [CI] 7.03, 61.63) and partial histological remission (OR 32.20, 95% CI 6.82, 152.04). There was a trend towards improvement in clinical symptoms with topical steroids as compared with placebo but it did not reach statistical significance (OR 2.72, 95 %CI 0.90, 8.23). Topical corticosteroids seem to be effective in inducing histological remission but may not have similar significant impact in improving clinical symptoms of EoE. Studies with large sample size are needed to uniformly validate symptom improvement in EoE. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley & Sons Australia, Ltd.

The borderland of migraine and epilepsy in children.

2016-06-01

To provide a review on the spectrum of migraine-epilepsy disorders in children. The migraine-epilepsy continuum covers a fascinating array of disorders that share many clinical similarities but also differ fundamentally in pathophysiology. In the pediatric population, its study can be complicated by the young age of those affected and the lack of clear understanding of the neurobiology of these disorders within the developing brain. This review serves to discuss the borderland of migraine and epilepsy in children. It will focus on epidemiology and comorbidity of the two disorders, possible mechanisms for shared pathophysiology informed by basic and translational science, and an overview of clinical similarities and differences. It will also discuss differentiation of migraine aura from childhood occipital epilepsies. Finally, the review concludes with a discussion of current classification methods for capturing cases on the migraine-epilepsy spectrum and a call for a united approach towards a better definition of this spectrum of disorders. Recent advances examining the migraine-epilepsy spectrum show clinicopathological similarities between the two disorders in children. Epidemiology demonstrates reciprocally increased incidences of epilepsy in migraineurs and of migraines in children with epilepsy, however, prospective longitudinal in children are currently lacking. Clinically, the two disorders show similarity in preictal, ictal, and postictal phenomena, with close temporal association of the two conditions described by the controversial term of "migralepsy." Basic science research has contributed significant improvements in understanding the generation of both of these episodic neurological conditions, with common links seen at a cellular level involving synaptic glutamate release and the provocation of varying propagation methods including cortical spreading depression in migraine and the paroxysmal depolarizing shift in epilepsy. Despite these significant gains in understanding, improved classification methods are required to identify and further study these interrelated conditions and move towards improved diagnosis and treatment of disorders on the migraine-epilepsy continuum in children. © 2016 American Headache Society.

Recently, it has been shown that TTS may be associated with severe clinical complications including death and that its prevalence is probably underestimated. Since current guidelines on TTS are lacking, it appears timely and important to provide an expert consensus statement on TTS. The clinical expert consensus document part I summarizes the current state of knowledge on clinical presentation and characteristics of TTS and agrees on controversies surrounding TTS such as nomenclature, different TTS types, role of coronary artery disease, and etiology. This consensus also proposes new diagnostic criteria based on current knowledge to improve diagnostic accuracy.

After stimulation, dendritic cells (DCs) mature and migrate to draining lymph nodes to induce immune responses. As such, autologous DCs generated ex vivo have been pulsed with tumour antigens and injected back into patients as immunotherapy. While DC vaccines have shown limited promise in the treatment of patients with advanced cancers including glioblastoma, the factors dictating DC vaccine efficacy remain poorly understood. Here we show that pre-conditioning the vaccine site with a potent recall antigen such as tetanus/diphtheria (Td) toxoid can significantly improve the lymph node homing and efficacy of tumour-antigen-specific DCs. To assess the effect of vaccine site pre-conditioning in humans, we randomized patients with glioblastoma to pre-conditioning with either mature DCs or Td unilaterally before bilateral vaccination with DCs pulsed with Cytomegalovirus phosphoprotein 65 (pp65) RNA. We and other laboratories have shown that pp65 is expressed in more than 90% of glioblastoma specimens but not in surrounding normal brain, providing an unparalleled opportunity to subvert this viral protein as a tumour-specific target. Patients given Td had enhanced DC migration bilaterally and significantly improved survival. In mice, Td pre-conditioning also enhanced bilateral DC migration and suppressed tumour growth in a manner dependent on the chemokine CCL3. Our clinical studies and corroborating investigations in mice suggest that pre-conditioning with a potent recall antigen may represent a viable strategy to improve anti-tumour immunotherapy.

Background This study examined therapist-patient interactions during clinical management with anti-depressant medication and pill-placebo. Methods The sample consisted of 80 patients on active medication and 40 patients in a pill-placebo condition from a randomized controlled trial for moderate to severe depression. Pharmacotherapist-patient interactions were characterized using observer ratings of the therapeutic alliance, pharmacotherapist-offered facilitative conditions, pharmacotherapist adherence to clinical management treatment guidelines, and pharmacotherapist competence. Patients, therapists, and raters were blind to treatment condition and outcome. Results Provision of greater nonspecific support (facilitative conditions) in early sessions predicted less subsequent improvement in depressive symptoms for patients receiving pill-placebo but not those receiving active medications, for which none of the process ratings predicted subsequent change. Early symptom change predicted later alliance and adherence in both conditions and therapist competence in the active condition. Conclusions Higher levels of support in early sessions predict poorer subsequent response among placebo patients. It remains unclear whether patients who are likely to be refractory elicit greater nonspecific support or whether the provision of such support has a deleterious effect in unmedicated patients. Differences in treatment process variables between conditions late in treatment are likely to be largely a consequence of symptom relief produced by active medications. PMID:19891806

Patient-reported outcome (PRO) refers to measures that emphasize the subjective view of patients about their health-related conditions and behaviors. Typically, PROs include self-report questionnaires and clinical interviews. Defining PROs for borderline personality disorder (BPD) is particularly challenging given the disorder's high symptomatic heterogeneity, high comorbidity with other psychiatric conditions, highly fluctuating symptoms, weak correlations between symptoms and functional outcomes, and lack of valid and reliable experimental measures to complement self-report data. Here, we provide an overview of currently used BPD outcome measures and discuss them from clinical, psychometric, experimental, and patient perspectives. In addition, we review the most promising leads to improve BPD PROs, including the DSM-5 Section III, the Recovery Approach, Ecological Momentary Assessments, and novel experimental measures of social functioning that are associated with functional and social outcomes.

2006-09-01

An adult male white Bengal tiger (Panthera tigris tigris) with pronounced atrophy of the pelvic musculature was diagnosed with degenerative osteoarthritis of the coxofemoral joints. Initial management with the nonsteroidal anti-inflammatory drug meloxicam and a semisynthetic sodium pentosan polysulfate resulted in clinical improvement and radiographic stabilization of the arthritic condition over several months. However, because pain was still evident, bilateral denervation of the coxofemoral joints was performed, successfully ameliorating the signs of osteoarthritic pain in the tiger. Meloxicam has shown good clinical efficacy for the treatment of osteoarthritis and other painful conditions in large felids. Coxofemoral joint denervation offers many advantages for the treatment of osteoarthritis in exotic carnivore species, and should be considered a viable treatment modality.

If Electronic Health Records contain a large amount of information about the patient's condition and response to treatment, which can potentially revolutionize the clinical practice, such information is seldom considered due to the complexity of its extraction and analysis. We here report on a first integration of an NLP framework for the analysis of clinical records of lung cancer patients making use of a telephone assistance service of a major Spanish hospital. We specifically show how some relevant data, about patient demographics and health condition, can be extracted; and how some relevant analyses can be performed, aimed at improving the usefulness of the service. We thus demonstrate that the use of EHR texts, and their integration inside a data analysis framework, is technically feasible and worth of further study.

Pro-inflammatory cytokines such as TNF-α are important in the pathogenesis of fatigue in conditions such as RA. This study aimed to determine whether fatigue improved in a cohort of RA patients with clinically relevant fatigue commencing anti-TNF-α therapy and, if so, to identify predictors of improvement. Participants recruited to a long-term observational cohort study (the British Society for Rheumatology Biologics Register for RA) provided information on fatigue using the 36-item Short Form Health Survey (SF-36) vitality subscale. The prevalence of severe baseline fatigue (SF-36 vitality ≤12.5) was calculated and improvements, considered as (i) absolute values and (ii) improvement from severe to non-severe fatigue (SF-36 vitality >12.5), were examined 6 months subsequently. A comprehensive set of putative predictors of fatigue improvement were evaluated using multivariable logistic regression. In 6835 participants the prevalence of severe baseline fatigue was 38.8%. Of those with severe fatigue, 70% reported clinically relevant improvement and 66% moved to the non-severe fatigue category (i.e. improvers). The mean change for improvers was three times the minimum clinically important difference for improvement (33.0 U). Independent baseline predictors of improvement were female sex [odds ratio (OR) 1.3 (95% CI 1.1, 1.7)], not being unemployed due to ill health [OR 1.5 (95% CI 1.2, 1.7)], low disability [OR 1.2 (95% CI 1.001, 1.5)], seropositivity [OR 1.2 (95% CI 0.98, 1.4)], not using steroids [OR 1.2 (95% CI 1.03, 1.5)], no history of hypertension [OR 1.4 (95% CI 1.1, 1.6)] or depression [OR 1.3 (95% CI 1.1, 1.5)] and good mental health [SF-36 mental health subscale >35; OR 1.4 (95% CI 1.2, 1.7)]. Fatigued RA patients reported substantial improvement in their fatigue after commencing anti-TNF-α therapy. Further, a number of clinical and psychosocial baseline factors identified those most likely to improve, supporting future stratified approaches to RA fatigue management. © The Author 2014.

Strategies to improve the quality of hospital care are needed if ongoing gains in child health and survival are to be made. We previously reported on improvements in the quality of case management in hospitals following a guideline-based intervention in Lao PDR, with variation in the degree of change achieved between clinical conditions. This study aims to understand the factors that influenced the uptake of the guideline-based intervention, and its impact on care. This qualitative study was embedded in a mixed-methods evaluation of guideline implementation in nine hospitals in Lao PDR. Focus groups and individual interviews were conducted with 70 health staff from central, provincial, and district hospitals. The interview guide was based on the Theoretical Domains Framework. Inductive content analysis was performed on interview transcripts to identify themes, supported by field notes from the intervention. Findings were triangulated against previously reported quantitative outcomes using driver diagrams. Key influences on guidelines uptake related to the guideline and intervention (filling a void, physical accessibility, comprehensibility, training in guideline use), health staff (behavior regulation, trust in guidelines, and beliefs about consequences), and the environment (social influences particularly consensus and incorporation into clinical norms). The major barrier was family preference for treatments in conflict with guideline recommendations. This study identifies contextual factors that explain, as well as validate previously identified improvements in care following guideline implementation in Lao PDR. It provides novel understanding of why the same intervention may have a differential impact on different clinical conditions.

Introduction Throughout the past three decades, increased scientific attention has been given to examining saffron’s (Crocus sativus L.) use as a potential therapeutic or preventive agent for a number of health conditions, including cancer, cardiovascular disease, and depression. Saffron has been shown to improve numerous health-related physiological to psychological outcomes. The purpose of this systematic review is to examine and categorize the current state of scientific evidence from randomized controlled trials (RCTs) regarding the efficacy of saffron on psychological and behavioral outcomes. Methods Electronic and non-electronic systematic searches were conducted to identify all relevant human clinical research on saffron. The search strategy was extensive and was designed according to the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)”. Reference lists of articles that met the inclusion criteria were searched. Only English language studies were reviewed. Results Twelve studies met our inclusion criteria. These studies examined the effects of saffron on psychological/behavioral outcomes with respect to the following health conditions: major depressive disorder (n = 6), premenstrual syndrome (n = 1), sexual dysfunction and infertility (n = 4), and weight loss/snacking behaviors (n = 1). The data from these studies support the efficacy of saffron in improving: depressive symptoms, premenstrual symptoms, sexual function, and satiety. Conclusion Findings from initial clinical trials suggest that saffron can improve the symptoms and effects of depression, premenstrual syndrome, sexual dysfunction and infertility, and excessive snacking behaviors. Larger multi-site clinical trials are needed to extend these preliminary findings. PMID:26165367

Adolescent and young adult kidney transplant recipients have worse graft outcomes than older and younger age groups. Difficulties in the process of transition, defined as the purposeful, planned movement of adolescents with chronic health conditions from child to adult-centered health care systems, may contribute to this. Improving the process of transition may improve adherence post-transfer to adult care services. The purpose of this study is to investigate whether a kidney transplant transfer clinic for adolescent and young adult kidney transplant recipients transitioning from pediatric to adult care improves adherence post-transfer. We developed a joint kidney transplant transfer clinic between a pediatric kidney transplant program, adult kidney transplant program, and adolescent medicine at two academic health centers. The transfer clinic facilitated communication between the adult and pediatric transplant teams, a face-to-face meeting of the patient with the adult team, and a meeting with the adolescent medicine physician. We compared the outcomes of 16 kidney transplant recipients transferred before the clinic was established with 16 patients who attended the clinic. The primary outcome was a composite measure of non-adherence. Non-adherence was defined as either self-reported medication non-adherence or displaying two of the following three characteristics: non-attendance at clinic, non-attendance for blood work appointments, or undetectable calcineurin inhibitor levels within 1 year post-transfer. The two groups were similar at baseline, with non-adherence identified in 43.75 % of patients. Non-adherent behavior in the year post-transfer, which included missing clinic visits, missing regular blood tests, and undetectable calcineurin inhibitor levels, was significantly lower in the cohort which attended the transfer clinic (18.8 versus 62.5 %, p = 0.03). The median change in estimated glomerular filtration rate (eGFR) in the year following transfer was smaller in the group that attended the transition clinic (-0.9 ± 13.2 ml/min/1.73 m(2)) compared to those who did not (-12.29 ± 14.9 ml/min/1.73 m(2)), p = 0.045. Attendance at a single kidney transplant transfer clinic was associated with improved adherence and renal function in the year following transfer to adult care. If these changes are sustained, they may improve long-term graft outcomes for adolescent kidney transplant recipients.

Background Use of home monitoring technologies can enhance care coordination and improve clinical outcomes in patients with diabetes and other chronic diseases. This study was designed to explore the feasibility of incorporating a telehealth system into an existing telephonic diabetes management program utilizing clinical pharmacists. Methods This observational study was conducted at three Providence Medical Group primary care clinics. Adults with a diagnosis of diabetes and a recent hemoglobin A1c (HbA1c) >8% were referred by their primary care provider to participate in the study. Participants utilized the telehealth system developed by Intel Corporation and were followed by clinical pharmacists who provide telephonic diabetes management. The primary clinical outcome measure was change in mean HbA1c. Secondary outcomes included blood glucose levels, participant self-management knowledge, and the degree of participant engagement. Results Mean HbA1c level decreased by 1.3% at the study end (p = .001). Based on participant satisfaction surveys and qualitative responses, participants were satisfied with the telehealth system. Mean blood glucose values decreased significantly over the 16-week study period from 178 mg/dl [standard deviation (SD) 67] at week 1 to 163 mg/dl (SD 64) at week 16 (p = .0002). Participants entered the study with moderate to good knowledge about managing their diabetes based on three questions, and no statistically significant improvement in knowledge was found post-study. Conclusion Telehealth technology can be a positive adjunct to the primary care team in managing diabetes or other chronic conditions to improve clinical outcomes. PMID:22027325

Introduction The purpose of this study was to investigate the effect of a 12-month Balance Training Program on balance, mobility and falling frequency in women with osteoporosis. Methods Sixty-six consecutive elderly women were selected from the Osteometabolic Disease Outpatient Clinic and randomized into 2 groups: the ‘Intervention’, submitted for balance training; and the ‘Control’, without intervention. Balance, mobility and falling frequency were evaluated before and at the end of the trial, using the Berg Balance Scale (BBS), the Clinical Test Sensory Interaction Balance (CTSIB) and the Timed “Up & Go” Test (TUGT). Intervention used techniques to improve balance consisting of a 1-hour session each week and a home-based exercise program. Results Sixty women completed the study and were analyzed. The BBS difference was significant higher in the Intervention group compared to Control (5.5 ± 5.67 vs −0.5 ± 4.88 score, p < 0.001). Similarly, the number of patients in the Intervention group presented improvement in two conditions of CTSIB compared to Control (eyes closed and unstable surface condition: 13 vs one patient, p < 0.001 and eyes open, visual conflict and unstable surface condition: 12 vs one patient, p < 0.001). Additionally, the differences between the TUGT were reduced in the Intervention group compared to Control (−3.65 ± 3.61 vs 2.27 ± 7.18 seconds, p< 0.001). Notably, this improvement was paralleled by a reduction in the number of falls/patient in the Intervention group compared to Control (−0.77 ± 1.76 vs 0.33 ± 0.96, p = 0.018). Conclusion This longitudinal prospective study demonstrated that an intervention using balance training is effective in improving functional and static balance, mobility and falling frequency in elderly women with osteoporosis.

Background: Whole body vibration exercise (WBVE) has been used as a safe and accessible exercise and important reviews have been published about the use of this exercise to manage diseases and to improve physical conditions of athletes The aim of this paper is to highlight the relevance of WBVE to soccer players, divers and combat athletes. Material and methods: This study was made through a systematic review of publications involving WBVE and the selected sports in two databases (Pubmed and PEDRo). Results: It were identified 10 studies involving WBVE and sports (6 of soccer, 2 of diving and 2 of sport combat) with 156 subjects (80 soccer players, 32 divers and 44 combat athletes), with age from 17 to 44 years old. Conclusion: The use of WBVE has proven to be a safe and useful strategy to improve the physical conditions of players of different sports. These findings may have clinical relevance and should be considered as a strategy to be used to try improve the physical conditions of players. PMID:28740940

Can health care organizations improve health behavior and treatment adherence?

PubMed

Bender, Bruce G

2014-04-01

Many Americans are failing to engage in both the behaviors that prevent and those that effectively manage chronic health conditions, including pulmonary disorders, cardiovascular conditions, diabetes, and cancer. Expectations that health care providers are responsible for changing patients' health behaviors often do not stand up against the realities of clinical care that include large patient loads, limited time, increasing co-pays, and restricted access. Organizations and systems that might share a stake in changing health behavior include employers, insurance payers, health care delivery systems, and public sector programs. However, although the costs of unhealthy behaviors are evident, financial resources to address the problem are not readily available. For most health care organizations, the return on investment for developing behavior change programs appears highest when addressing treatment adherence and disease self-management, and lowest when promoting healthy lifestyles. Organizational strategies to improve adherence are identified in 4 categories: patient access, provider training and support, incentives, and information technology. Strategies in all 4 categories are currently under investigation in ongoing studies and have the potential to improve self-management of many chronic health conditions.

A growing number of clinical trials and case reports support qualitative claims that use of an elevated vacuum suspension (EVS) prosthesis improves residual-limb health on the basis of self-reported questionnaires, clinical outcomes scales, and wound closure studies. Here, we report first efforts to quantitatively assess residual-limb circulation in response to EVS. Residual-limb skin health and perfusion of people with lower-limb amputation (N = 10) were assessed during a randomized crossover study comparing EVS with nonelevated vacuum suspension (control) over a 32 wk period using noninvasive probes (transepidermal water loss, laser speckle imaging, transcutaneous oxygen measurement) and functional hyperspectral imaging approaches. Regardless of the suspension system, prosthesis donning decreased perfusion in the residual limb under resting conditions. After 16 wk of use, EVS improved residual-limb oxygenation during treadmill walking. Likewise, prosthesis-induced reactive hyperemia was attenuated with EVS following 16 wk of use. Skin barrier function was preserved with EVS but disrupted after control socket use. Taken together, outcomes suggest chronic EVS use improves perfusion and preserves skin barrier function in people with lower-limb amputation.

The external quality assessment schemes (EQAS) organizer provides a suitable program to monitor and improve the quality of human immunodeficiency virus (HIV) testing laboratories with EQAS panels prepared under various conditions. The aim of the current study was to investigate the effects of human plasma samples on the EQAS results of HIV obtained from hospital-based clinical laboratories. From 2007 to 2009, HIV EQAS panels consisted of four to six samples that consisted of undiluted positive and negative samples and were provided to laboratories twice per year. Up until the first half EQAS in 2008, EQAS panel materials were obtained by converting acid citrate dextrose treated plasma to serum via chemical treatment with CaCl2. Beginning with the second EQAS in 2008, all materials were prepared without the defibrination process. Approximately 300 HIV clinical laboratories participated in this program. The overall performance of clinical laboratories was shown to be improved when using unrecalcified plasma panels compared with recalcified panels. Significant differences were observed in EIA analyses of plasma for both positive (p<0.001) and negative (p<0.001) samples between the recalcified and unrecalcified groups. Our finding suggested that defibrination status of EQAS panels might affect the results of anti-HIV EQAS of Korean HIV testing laboratories.

The prevalence rate of transsexualism varies from 1 to 50,000, to 1 to 100,000. Although it remains an infrequent affliction, transsexualism generates usually major suffering and may be responsible of many complications like suicide, self-mutilations, affective disorders and social disabilities. Since the first descriptions of Esquirol in the nineteenth, the medical community has always been questioned on medical, legal, social or ethical aspects of transsexualism. The aetiology of the trouble is still unknown. In the absence of biological marker, the syndrome of transsexualism can be defined only with clinical criteria. The main differential diagnosis are sexual ambiguities and psychotic disorders. For the specialists, satisfying the patients demand of a surgical and social reassignment still remains the only way to improve their clinical condition and avoid the onset of many dramatic complications. Without any treatment, the evolution of the trouble is chronic, without remission. Longitudinal studies of transsexual patients with a five year follow-up demonstrated subjective improvement in two thirds of the patients and don't find either higher rates of suicides nor psychotic decompensations after surgery and hormonotherapy. Clinical and neuropsychological studies of sexually differentiated cognitive abilities of transsexual patients, before and after hormonotherapy, could allow us in improving the understanding of sexual differences of the brain.

The Health Of Patients' Eyes (HOPE) Glaucoma study. The effectiveness of a 'glaucoma personal record' for newly diagnosed glaucoma patients: study protocol for a randomised controlled trial.

Glaucoma involves progressive optic nerve fibre loss, subsequently leading to irreversible and disabling visual field defects. In Europe, the prevalence of glaucoma is approximately 2.2 % of all people aged over 40 years; this equates to 12 million people. Glaucoma patients require regular lifelong follow-up, contributing to a large financial and resource burden for the National Health Service (NHS) in the UK. This study aims to determine whether providing newly diagnosed glaucoma patients with a personalised client-held eye health summary ('glaucoma personal record'), improves patients' knowledge of their glaucoma condition. A potential long-term benefit could be improved self-management and henceforth a slower rate of deterioration. HOPE Glaucoma is a 3-year, prospective, parallel-group, pragmatic, single-centred, randomised controlled trial. An anticipated 122 adults, newly diagnosed with glaucoma (including ocular hypertension, suspected glaucoma and/or chronic open-angle glaucoma) will be recruited from a nurse-led ophthalmology outpatient clinic at a medium-sized NHS Trust. Participants will be randomly allocated to receive standard clinical care (control arm) or standard care plus a glaucoma personal record, detailing the current state of their condition (interventional arm). Participant assessments are designed to test whether provision of a glaucoma personal record 1) improves patient knowledge of glaucoma and 2) contributes to improvements in clinical outcomes, i.e. delay of visual field loss. The primary outcome measure is better client knowledge of glaucoma at the 9-12 month follow-up visit. Secondary outcome measures include the rate of visual field loss and patient-reported outcome measures on visual function (National Eye Institute VFQ - 25) measured at baseline, 9-12 months, 24 months and 36 months. Estimating a 20 % drop-out rate, the study will have 90 % power to detect a mean two-point difference in glaucoma knowledge score between groups at 5 % significance - based on two-sided Mann-Whitney U test. If a glaucoma personal record is found to significantly improve glaucoma patients' knowledge of their condition, this intervention could potentially provide a low-cost, straightforward tool to educate and engage glaucoma patients. Subsequently, this could have the potential to increase patient self-management and therefore allow glaucoma patients to prolong their sight functionality for longer.

Symptoms account for more than 400 million clinic visits annually in the USA. The SPADE symptoms (sleep, pain, anxiety, depression, and low energy/fatigue) are particularly prevalent and undertreated. To assess the effectiveness of providing PROMIS (Patient-Reported Outcome Measure Information System) symptom scores to clinicians on symptom outcomes. Randomized clinical trial conducted from March 2015 through May 2016 in general internal medicine and family practice clinics in an academic healthcare system. Primary care patients who screened positive for at least one SPADE symptom. After completing the PROMIS symptom measures electronically immediately prior to their visit, the 300 study participants were randomized to a feedback group in which their clinician received a visual display of symptom scores or a control group in which scores were not provided to clinicians. The primary outcome was the 3-month change in composite SPADE score. Secondary outcomes were individual symptom scores, symptom documentation in the clinic note, symptom-specific clinician actions, and patient satisfaction. Most patients (84%) had multiple clinically significant (T-score ≥ 55) SPADE symptoms. Both groups demonstrated moderate symptom improvement with a non-significant trend favoring the feedback compared to control group (between-group difference in composite T-score improvement, 1.1; P = 0.17). Symptoms present at baseline resolved at 3-month follow-up only one third of the time, and patients frequently still desired treatment. Except for pain, clinically significant symptoms were documented less than half the time. Neither symptom documentation, symptom-specific clinician actions, nor patient satisfaction differed between treatment arms. Predictors of greater symptom improvement included female sex, black race, fewer medical conditions, and receiving care in a family medicine clinic. Simple feedback of symptom scores to primary care clinicians in the absence of additional systems support or incentives is not superior to usual care in improving symptom outcomes. clinicaltrials.gov identifier: NCT02383862.

Pediatricians manage skin conditions such as atopic dermatitis (AD) but report that their dermatologic training is inadequate. Online modules may enhance medical education when sufficient didactic or clinical teaching experiences are lacking. We assessed whether an online module about AD improved pediatric residents' knowledge and changed their clinical management of AD. Target and control cohorts of pediatric residents from two institutions were recruited. Target subjects took a 30-question test about AD early in their residency, reviewed the online module, and repeated the test 6 months and 1 year later. The control subjects, who had 1 year of clinical experience but had not reviewed the online module, also took the test. The mean percentage of correct answers was calculated and compared using two-sided, two-sample independent t tests and repeated-measures analysis of variance. For a subset of participants, clinical documentation from AD encounters was reviewed and 13 practice behaviors were compared using the Fisher exact test. Twenty-five subjects in the target cohort and 29 subjects in the control cohort completed the study. The target cohort improved from 18.0 ± 3.2 to 23.4 ± 3.4 correctly answered questions over 1 year (P < .001). This final value was greater than that of the control cohort (20.7 ± 4.5; P = .01). Meaningful differences in practice behaviors were not seen. Pediatric residents who reviewed an online module about AD demonstrated statistically significant improvement in disease-specific knowledge over time and had statistically significantly higher scores than controls. Online dermatology education may effectively supplement traditional clinical teaching. © 2017 Wiley Periodicals, Inc.

Revisiting the continuum model of tendon pathology: what is its merit in clinical practice and research?

PubMed Central

Cook, J L; Rio, E; Purdam, C R; Docking, S I

2016-01-01

The pathogenesis of tendinopathy and the primary biological change in the tendon that precipitates pathology have generated several pathoaetiological models in the literature. The continuum model of tendon pathology, proposed in 2009, synthesised clinical and laboratory-based research to guide treatment choices for the clinical presentations of tendinopathy. While the continuum has been cited extensively in the literature, its clinical utility has yet to be fully elucidated. The continuum model proposed a model for staging tendinopathy based on the changes and distribution of disorganisation within the tendon. However, classifying tendinopathy based on structure in what is primarily a pain condition has been challenged. The interplay between structure, pain and function is not yet fully understood, which has partly contributed to the complex clinical picture of tendinopathy. Here we revisit and assess the merit of the continuum model in the context of new evidence. We (1) summarise new evidence in tendinopathy research in the context of the continuum, (2) discuss tendon pain and the relevance of a model based on structure and (3) describe relevant clinical elements (pain, function and structure) to begin to build a better understanding of the condition. Our goal is that the continuum model may help guide targeted treatments and improved patient outcomes. PMID:27127294

Patients suffering from quadriceps muscle weakness secondary to osteoarthritis or after surgeries, such as total knee arthroplasty, appear to benefit from the use of neuromuscular electrical stimulation (NMES), which can improve muscle strength and function, range of motion, exercise capacity, and quality of life. Several modalities exist that deliver this therapy. However, with the ever-increasing demand to improve clinical efficiency and costs, digitalize healthcare, optimize data collection, improve care coordination, and increase patient compliance and engagement, newer devices incorporating technologies that facilitate these demands are emerging. One of these devices, an app-controlled home-based NMES therapy system that allows patients to self-manage their condition and potentially increase adherence to the treatment, incorporates a smartphone-based application which allows a cloud-based portal that feeds real-time patient monitoring to physicians, allowing patients to be supported remotely and given feedback. This device is a step forward in improving both patient care and physician efficiency, as well as decreasing resource utilization, which potentially may reduce healthcare costs.

Chronic pain is a debilitating condition with a multidimensional impact on the lives of patients, their families and communities. The public health burden of chronic pain is gathering recognition as a major healthcare problem in its own right and deserves closer attention. The challenge in treating chronic pain is to provide effective clinical management of a complex, multifaceted set of conditions that require a coordinated strategy of care. Epidemiological data and patient surveys have highlighted the areas of pain management that might be improved. These include a need for better understanding and documentation of the symptoms of chronic pain, standardized levels of care, improved communication among clinical personnel and with patients, and an updated education program for clinicians. For these reasons, new strategies aimed at improving the standards of pain management are needed. The Pain Associates' International Network (P.A.I.N.) Initiative was set up to devise practical methods for improving the quality of pain management for patients. These strategies have recently been put into practice through a number of activities: P.A.I.N. Workshops are meetings of international pain management professionals dedicated to discussing current management strategies and producing consensus recommendations for improving standards of care; P.A.I.N. Quality is a unique software program designed to help treating clinicians to document patient data and derive effective treatment plans; P.A.I.N. Online provides a web site forum for discussion of pain management topics; and P.A.I.N. Management is a clinician education program providing up-to-date training in pain management.

Oxygen is a life-saving, essential medicine that is important for the treatment of many common childhood conditions. Improved oxygen systems can reduce childhood pneumonia mortality substantially. However, providing oxygen to children is challenging, especially in small hospitals with weak infrastructure and low human resource capacity. This trial will evaluate the implementation of improved oxygen systems at secondary-level hospitals in southwest Nigeria. The improved oxygen system includes: a standardised equipment package; training of clinical and technical staff; infrastructure support (including improved power supply); and quality improvement activities such as supportive supervision. Phase 1 will involve the introduction of pulse oximetry alone; phase 2 will involve the introduction of the full, improved oxygen system package. We have based the intervention design on a theory-based analysis of previous oxygen projects, and used quality improvement principles, evidence-based teaching methods, and behaviour-change strategies. We are using a stepped-wedge cluster randomised design with participating hospitals randomised to receive an improved oxygen system at 4-month steps (three hospitals per step). Our mixed-methods evaluation will evaluate effectiveness, impact, sustainability, process and fidelity. Our primary outcome measures are childhood pneumonia case fatality rate and inpatient neonatal mortality rate. Secondary outcome measures include a range of clinical, quality of care, technical, and health systems outcomes. The planned study duration is from 2015 to 2018. Our study will provide quality evidence on the effectiveness of improved oxygen systems, and how to better implement and scale-up oxygen systems in resource-limited settings. Our results should have important implications for policy-makers, hospital administrators, and child health organisations in Africa and globally.

To offer individualized restorative strategies for patients receiving dental implants in the anterior esthetic zone but with inappropriate available conditions and evaluate the clinical outcomes. Forty-six patients with 58 implants were recruited for the study in accordance with the criteria and received individualized implant prostheses in the anterior esthetic zone. The patients were followed up for 3-24 months, and the clinical outcomes were evaluated by pink and white esthetic scores (PES/WES). The patients were from 18 to 69 years old, and followed up for 12.6 months in average. According to the third month follow-up esthetic scores, for PES, 1.72% of the patients got low scores, 44.83% got medium scores and 53.45% got high scores; For WES, 0% got low scores, 20.69% got medium scores and 79.31% got high scores. No implant failure or peri-implantitis occurred. Individualized restorative designs for implants in the esthetic zone can effectively improve the appearance of the prostheses which originally have no appropriate available space. Close follow-up and monitoring of the peri-implant soft tissue and proper oral hygiene instructions are important to ensure the conditions of the prostheses.

The relation was investigated between hemiparetic arm function improvement and brain cortical perfusion (BCP) change during voluntary muscle contraction (VOL), EMG-controlled FES (EMG-FES) and simple electrical muscle stimulation (ES) before and after EMG-FES therapy in chronic stroke patients. Sixteen chronic stroke patients with moderate residual hemiparesis underwent 5 months of task-orientated EMG-FES therapy of the paretic arm once or twice a week. Before and after treatment, arm function was clinically evaluated and BCP during VOL, ES and EMG-FES were assessed using multi-channel near-infrared spectroscopy. BCP in the ipsilesional sensory-motor cortex (SMC) was greater during EMG-FES than during VOL or ES; therefore, EMG-FES caused a shift in the dominant BCP from the contralesional to ipsilesional SMC. After EMG-FES therapy, arm function improved in most patients, with some individual variability, and there was significant improvement in Fugl-Meyer (FM) score and maximal grip strength (GS). Clinical improvement was accompanied by an increase in ipsilesional SMC activation during VOL and EMG-FES condition. The EMG-FES may have more influence on ipsilesional BCP than VOL or ES alone. The sensory motor integration during EMG-FES therapy might facilitate BCP of the ipsilesional SMC and result in functional improvement of hemiparetic upper extremity.

Clinical research evidence of cupping therapy in China: a systematic literature review

PubMed Central

2010-01-01

Background Though cupping therapy has been used in China for thousands of years, there has been no systematic summary of clinical research on it. This review is to evaluate the therapeutic effect of cupping therapy using evidence-based approach based on all available clinical studies. Methods We included all clinical studies on cupping therapy for all kinds of diseases. We searched six electronic databases, all searches ended in December 2008. We extracted data on the type of cupping and type of diseases treated. Results 550 clinical studies were identified published between 1959 and 2008, including 73 randomized controlled trials (RCTs), 22 clinical controlled trials, 373 case series, and 82 case reports. Number of RCTs obviously increased during past decades, but the quality of the RCTs was generally poor according to the risk of bias of the Cochrane standard for important outcome within each trials. The diseases in which cupping was commonly employed included pain conditions, herpes zoster, cough or asthma, etc. Wet cupping was used in majority studies, followed by retained cupping, moving cupping, medicinal cupping, etc. 38 studies used combination of two types of cupping therapies. No serious adverse effects were reported in the studies. Conclusions According to the above results, quality and quantity of RCTs on cupping therapy appears to be improved during the past 50 years in China, and majority of studies show potential benefit on pain conditions, herpes zoster and other diseases. However, further rigorous designed trials in relevant conditions are warranted to support their use in practice. PMID:21078197

Medical therapy is best for atherosclerotic renal artery stenosis: Arguments for.

PubMed

Annigeri, R A

2012-01-01

Atherosclerotic renal artery stenosis (ARAS) is a common condition that causes hypertension and reduction in the glomerular filtration rate and is an independent risk factor for death. Despite high technical success, the clinical benefit of renal artery (RA) angioplasty with stenting in ARAS remains doubtful. The published randomized clinical trials provide no support for the notion that renal angioplasty with stenting significantly improves blood pressure, preserves renal function, or reduces episodes of congestive heart failure in patients with ARAS. RA stenting is associated with procedure-related morbidity and mortality. Agents to block the renin-angiotensin-aldosterone system improve outcome and should be a part of a multifaceted medical regimen in ARAS. Medical therapy effectively controls atherosclerotic renovascular disease at all levels of vasculature and hence is the best therapy for ARAS.

Adoptive Cell Transfer Therapy

Dudley, Mark E.; Rosenberg, Steven A.

Adoptive cell transfer therapy has developed into a potent and effective treatment for patients with metastatic melanoma. Current application of this therapy relies on the ex vivo generation of highly active, highly avid tumor-reactive lymphocyte cultures from endogenous tumor infiltrating lymphocytes or on the genetic engineering of cells using antigen receptor genes to express de novo tumor antigen recognition. When anti-tumor lymphocyte cultures are administered to autologous patients with high dose interleukin-2 following a lymphodepleting conditioning regimen, the cells can expand in vivo, traffic to tumor, and mediate tumor regression and durable objective clinical responses. Current investigation seeks to improve the methods for generating and administering the lymphocyte cultures, and future clinical trials aim to improve durable response rates and extend the patient populations that are candidates for treatment.

The study evaluated an intervention to help veterans with psychiatric disabilities, who face a unique set of challenges concerning money management. A randomized clinical trial was conducted of a brief (one to three hours) psychoeducational, recovery-oriented money management intervention called $teps for Achieving Financial Empowerment ($AFE). Analyses revealed no main effects on outcomes of random assignment to $AFE (N=67) or a control condition consisting of usual care (N=77). Veterans who reported using $AFE skills showed significantly lower impulsive buying, more responsible spending, higher rates of engaging in vocational activities, and greater number of work hours compared with veterans in the control condition. Findings have clinical implications for case management services involving informal money management assistance. Offering veterans with psychiatric disabilities a one-time money management intervention is unlikely to lead to substantial changes. Results imply that efforts to improve psychosocial outcomes among veterans must not only teach but also increase use of money management skills.

Spinal Cord Stimulation: Clinical Efficacy and Potential Mechanisms.

PubMed

Sdrulla, Andrei D; Guan, Yun; Raja, Srinivasa N

2018-03-11

Spinal cord stimulation (SCS) is a minimally invasive therapy used for the treatment of chronic neuropathic pain. SCS is a safe and effective alternative to medications such as opioids, and multiple randomized controlled studies have demonstrated efficacy for difficult-to-treat neuropathic conditions such as failed back surgery syndrome. Conventional SCS is believed mediate pain relief via activation of dorsal column Aβ fibers, resulting in variable effects on sensory and pain thresholds, and measurable alterations in higher order cortical processing. Although potentiation of inhibition, as suggested by Wall and Melzack's gate control theory, continues to be the leading explanatory model, other segmental and supraspinal mechanisms have been described. Novel, non-standard, stimulation waveforms such as high-frequency and burst have been shown in some studies to be clinically superior to conventional SCS, however their mechanisms of action remain to be determined. Additional studies are needed, both mechanistic and clinical, to better understand optimal stimulation strategies for different neuropathic conditions, improve patient selection and optimize efficacy. © 2018 World Institute of Pain.

Severe cutaneous adverse reactions (SCARs), previously thought to be idiosyncratic or unpredictable, are a deadly form of adverse drug reactions with skin manifestations. Current pharmacogenomic studies of SCARs have made important strides, as the prevention of SCARs, to some extent, appears attainable with the identification of genetic variants for genes encoding drug-metabolizing enzymes and human leukocyte antigens (HLAs). Despite the improvement of incidence, a treatment guideline for this devastating condition is still unavailable, highlighting the inadequacy of contemporary accepted therapeutic interventions. As such, prompt withdrawal of causative drugs is believed to be a priority of patient management. In this review, we discuss recent cutting-edge findings concerning the discovery of biomarkers for SCARs and their clinical utilities in the better prediction and early diagnosis of this disease. The knowledge compiled herein provides clues for future investigations on deciphering additional genetic markers for SCARs and the design of clinical trials for the prospective identification of subjects at genetic risk for this condition, ultimately personalizing the medicine.

Children with medical complexity (CMC) have medical fragility and intensive care needs that are not easily met by existing health care models. CMC may have a congenital or acquired multisystem disease, a severe neurologic condition with marked functional impairment, and/or technology dependence for activities of daily living. Although these children are at risk of poor health and family outcomes, there are few well-characterized clinical initiatives and research efforts devoted to improving their care. In this article, we present a definitional framework of CMC that consists of substantial family-identified service needs, characteristic chronic and severe conditions, functional limitations, and high health care use. We explore the diversity of existing care models and apply the principles of the chronic care model to address the clinical needs of CMC. Finally, we suggest a research agenda that uses a uniform definition to accurately describe the population and to evaluate outcomes from the perspectives of the child, the family, and the broader health care system.

2014-12-03

The cellular and molecular mechanisms underpinning tissue repair and its failure to heal are still poorly understood, and current therapies are limited. Poor wound healing after trauma, surgery, acute illness, or chronic disease conditions affects millions of people worldwide each year and is the consequence of poorly regulated elements of the healthy tissue repair response, including inflammation, angiogenesis, matrix deposition, and cell recruitment. Failure of one or several of these cellular processes is generally linked to an underlying clinical condition, such as vascular disease, diabetes, or aging, which are all frequently associated with healing pathologies. The search for clinical strategies that might improve the body's natural repair mechanisms will need to be based on a thorough understanding of the basic biology of repair and regeneration. In this review, we highlight emerging concepts in tissue regeneration and repair, and provide some perspectives on how to translate current knowledge into viable clinical approaches for treating patients with wound-healing pathologies.

Developing clinical practice guidelines: reviewing, reporting, and publishing guidelines; updating guidelines; and the emerging issues of enhancing guideline implementability and accounting for comorbid conditions in guideline development

PubMed Central

2012-01-01

Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this third paper we discuss the issues of: reviewing, reporting, and publishing guidelines; updating guidelines; and the two emerging issues of enhancing guideline implementability and how guideline developers should approach dealing with the issue of patients who will be the subject of guidelines having co-morbid conditions.

Integrated Theory of Health Behavior Change

PubMed Central

RYAN, POLLY

2009-01-01

An essential characteristic of advanced practice nurses is the use of theory in practice. Clinical nurse specialists apply theory in providing or directing patient care, in their work as consultants to staff nurses, and as leaders influencing and facilitating system change. Knowledge of technology and pharmacology has far outpaced knowledge of how to facilitate health behavior change, and new theories are needed to better understand how practitioners can facilitate health behavior change. In this article, the Integrated Theory of Health Behavior Change is described, and an example of its use as foundation to intervention development is presented. The Integrated Theory of Health Behavior Change suggests that health behavior change can be enhanced by fostering knowledge and beliefs, increasing self-regulation skills and abilities, and enhancing social facilitation. Engagement in self-management behaviors is seen as the proximal outcome influencing the long-term distal outcome of improved health status. Person-centered interventions are directed to increasing knowledge and beliefs, self-regulation skills and abilities, and social facilitation. Using a theoretical framework improves clinical nurse specialist practice by focusing assessments, directing the use of best-practice interventions, and improving patient outcomes. Using theory fosters improved communication with other disciplines and enhances the management of complex clinical conditions by providing holistic, comprehensive care. PMID:19395894

a) to examine the demographic and clinical characteristics of repeat-presentations to an adolescent urgent psychiatric clinic, and b) to compare them with single-time presentation. This 18-month retrospective study compared repeat-presenters to age and gender matched single-time presenters. Demographic variables included age gender and ethnicity. Clinical variables included reason for referral, family history, diagnosis, recommendations and compliance. Data were analyzed using descriptive statistics, McNemar's Chi-square tests for matched pairs, and conditional logistic regression. Of 624 assessments 24% (N=151) were repeat-presentations. Compared with single-presentation, repeat-presentation group had a higher proportion of Aboriginal youth (X2 (1) = 108.28 p < 0.01), a higher proportion in special educational placement (X2 (1) = 6.82, p < 0.01), a higher proportion with a family history of anxiety disorders (X2 (1) = 10.62, p = 0.01) and substance use disorder (X2 (1) = 18.99, p < 0.01). Conditional logistic regression results suggested that repeat-presentation group had higher odds of past hospital admission (OR: 3.50, p < 0.01) higher odds of family history of mood disorders (OR: 4.86, p < 0.01) and of antisocial disorders (OR: 4.97, p = 0.02), and lower odds of recommendation compliance (OR: 0.10, p < 0.01). Repeat-presentations for urgent psychiatric consultation constitute a quarter of referrals to the urgent psychiatric clinic. Identifying and addressing factors that contribute to repeat-presentations may, assist in improving treatment compliance by ensuring focused interventions and service delivery for these youth. In turn, this will improve access to the limited urgent services for other youth.

Neurological and psychiatric disorders are characterized by several disabling symptoms for which effective, mechanism-based treatments remain elusive. Consequently, more advanced non-invasive therapeutic methods are required. A method that may modulate brain activity and be viable for use in clinical practice is repetitive transcranial magnetic stimulation (rTMS). It is a non-invasive procedure whereby a pulsed magnetic field stimulates electrical activity in the brain. Here, we focus on the basic foundation of rTMS, the main stimulation parametters, the factors that influence individual responses to rTMS and the experimental advances of rTMS that may become a viable clinical application to treat neurological and psychiatric disorders. The findings showed that rTMS can improve some symptoms associated with these conditions and might be useful for promoting cortical plasticity in patients with neurological and psychiatric disorders. However, these changes are transient and it is premature to propose these applications as realistic therapeutic options, even though the rTMS technique has been evidenced as a potential modulator of sensorimotor integration and neuroplasticity. Functional imaging of the region of interest could highlight the capacity of rTMS to bring about plastic changes of the cortical circuitry and hint at future novel clinical interventions. Thus, we recommend that further studies clearly determine the role of rTMS in the treatment of these conditions. Finally, we must remember that however exciting the neurobiological mechanisms might be, the clinical usefulness of rTMS will be determined by its ability to provide patients with neurological and psychiatric disorders with safe, long-lasting and substantial improvements in quality of life.

Translational neuropathic pain research: A clinical perspective.

PubMed

Bouhassira, D; Attal, N

2016-12-03

Neuropathic pain encompasses a broad range of conditions associated with a lesion or disease of the peripheral or central somatosensory system and its prevalence in the general population may be as high as 7-8%. The interest in the pathophysiology of neuropathic pain has increased over the last two decades with an exponential increase in the number of experimental studies. However, despite the hopes raised by scientific discoveries, there has been no rational development of a truly new class of drugs. This situation revealing the limitations of certain experimental models, also results of limitations in clinical research. One of the reasons for the therapeutic difficulties in these patients is probably due to the fact that treatments are used in a uniform fashion whatever the clinical picture, while these syndromes are in fact highly heterogeneous. Clinical advances have recently been made in this field, following the validation of new specific clinical tools and the standardization of quantitative sensory testing paradigms facilitating improvements in the clinical characterization of these syndromes. It has been clearly demonstrated that neuropathic pain is a consistent clinical entity, but it is multidimensional in terms of its clinical expression, with different sensory profiles, potentially reflecting specific pathophysiological mechanisms. This new conceptualization of neuropathic pain should improve the characterization of the responder profiles in clinical trials and provide valuable information for the development of new and more clinically sound translational approaches in experimental models in animals.

Spinal epidural lymphoma with compressive myelopathy is a rarely found condition. The aims of this study are to describe the clinical features and to analyze its treatment outcome and prognostic factors. We searched for all pediatric patients with newly diagnosed spinal epidural lymphoma from 1999 to 2014 in our institution. We evaluated the clinical features, including neurologic status, time interval to treatment, treatment modality, and outcomes. Twelve of 302 pediatric patients with lymphoma (4.0%) presented with compressive myelopathy, and they were all found to have spinal epidural lymphoma. In 11 patients, epidural space was the only site of lymphoma involvement. The median age was 9 years (range, 5-15 years). Common initial symptoms were back pain and low extremity weakness. Surgery was performed on 9 patients, biopsy on 2 patients, and radiation therapy on 1 patient. In 9 patients who received surgery, 6 patients with preoperative motor power grade ≥II attained improvement in weakness. Three patients with preoperative motor power grade

OBJECTIVE: Community health centers (HCs) provide care for millions of medically underserved Americans with disproportionate burdens of hypertension and hyperlipidemia. For both conditions, treatment guidelines recently became more stringent and quality improvement (QI) efforts have intensified. We assessed hypertension and hyperlipidemia management in HCs during this time of guideline revision and increased QI efforts. DESIGN: Cross-sectional chart review. SETTING AND PARTICIPANTS: Eleven Midwestern HCs for 2000 and 9 for 2002 provided audit data from 2,976 randomly chosen patients with hypertension and/or hyperlipidemia. MEASUREMENT: Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC VI/VII) and National Cholesterol Education Program Adult Treatment Panel (NCEP-ATP III) guidelines were used to assess management of these conditions. RESULTS: Hypertension (2000, N=808; 2002, N=692) and hyperlipidemia (2000, N=774; 2002, N=702) outcomes improved for specific clinical subgroups. Hypertensive patients with 1 or more cardiovascular risk factors demonstrated significant improvement (34% vs. 45% controlled at <140/90 mm Hg, p=0.02). Hypertension control for persons with diabetes, renal failure and heart failure increased (16% vs. 28% controlled at <130/85 mm Hg, p=0.006). LDL control increased significantly for patients with 2 or more risk factors (39% vs. 58% controlled at <130 mg/dl, p=0.008). Other clinical subgroups showed trends toward better control, although there was insufficient power to detect significant differences for these groups. CONCLUSION: Hypertension and hyperlipidemia outcomes improved for some risk groups; however, ongoing QI is necessary.

Limited information is available about clinical predictors of in-hospital mortality in acute unselected medical admissions. Such information could assist medical decision-making.To develop a clinical model for predicting in-hospital mortality in unselected acute medical admissions and to test the impact of secondary conditions on hospital mortality.This is an analysis of the medical records of patients admitted to internal medicine wards at one university-affiliated hospital. Data obtained from the years 2013 to 2014 were used as a derivation dataset for creating a prediction model, while data from 2015 was used as a validation dataset to test the performance of the model. For each admission, a set of clinical and epidemiological variables was obtained. The main diagnosis at hospitalization was recorded, and all additional or secondary conditions that coexisted at hospital admission or that developed during hospital stay were considered secondary conditions.The derivation and validation datasets included 7268 and 7843 patients, respectively. The in-hospital mortality rate averaged 7.2%. The following variables entered the final model; age, body mass index, mean arterial pressure on admission, prior admission within 3 months, background morbidity of heart failure and active malignancy, and chronic use of statins and antiplatelet agents. The c-statistic (ROC-AUC) of the prediction model was 80.5% without adjustment for main or secondary conditions, 84.5%, with adjustment for the main diagnosis, and 89.5% with adjustment for the main diagnosis and secondary conditions. The accuracy of the predictive model reached 81% on the validation dataset.A prediction model based on clinical data with adjustment for secondary conditions exhibited a high degree of prediction accuracy. We provide a proof of concept that there is an added value for incorporating secondary conditions while predicting probabilities of in-hospital mortality. Further improvement of the model performance and validation in other cohorts are needed to aid hospitalists in predicting health outcomes.

The purpose of this study is to present clinical outcome data from a 2-year post-market study of a viscoelastic one-piece cervical total disc replacement (TDR) in Europe. Thirty-nine patients were implanted at five surgical sites in an European post-market clinical study. Clinical outcomes included improvement of neck disability index (NDI) and visual analog scale scores for neck and arm pain from baseline to 2-year follow-up, neurological examinations, patients view on the success of surgery, complications, and subsequent surgical interventions. Thirty patients had the Freedom ® Cervical Disc (FCD) implanted at a single level, and nine patients were implanted at two adjacent levels. The population had a similar distribution of male [20] and female [19] subjects, with a mean age of 45 years. All self-administered outcome measures showed significant clinically important improvements from baseline to the 2-year follow-up. Mean preoperative NDI score improved from 48% to 20%, 13%, 8%, 6% and 4% at 6 weeks, 3, 6, 12, and 24 months, respectively. Average preoperative visual analog scale (VAS) scores of the neck, right and left arm pain intensity and frequency showed significant improvement. All neurological outcome measurements showed immediate improvement from preoperative values and continued improvement throughout 2 years follow-up. From pre-op to 24 months, neurological deficits declined in the population from 21% to 6% for reflex function, 62% to 17% for sensory function, and 38% to 3% for motor function. No patients experienced a deterioration in any measured outcomes compared with the preoperative situation. Patient satisfaction increased over 2 years post-op, with 83% of patients responding that they would "definitely" choose to have the same treatment for their neck/arm condition and another 11% responding that they would "probably" choose to have the same treatment. The FCD performs as expected in patients with single-level and two-level degenerative disc disease.

Implementing telehealth to support medical practice in rural/remote regions: what are the conditions for success?

Telehealth, as other information and communication technologies (ICTs) introduced to support the delivery of health care services, is considered as a means to answer many of the imperatives currently challenging health care systems. In Canada, many telehealth projects are taking place, mostly targeting rural, remote or isolated populations. So far, various telehealth applications have been implemented and have shown promising outcomes. However, telehealth utilisation remains limited in many settings, despite increased availability of technology and telecommunication infrastructure. A qualitative field study was conducted in four remote regions of Quebec (Canada) to explore perceptions of physicians and managers regarding the impact of telehealth on clinical practice and the organisation of health care services, as well as the conditions for improving telehealth implementation.

Background Telehealth, as other information and communication technologies (ICTs) introduced to support the delivery of health care services, is considered as a means to answer many of the imperatives currently challenging health care systems. In Canada, many telehealth projects are taking place, mostly targeting rural, remote or isolated populations. So far, various telehealth applications have been implemented and have shown promising outcomes. However, telehealth utilisation remains limited in many settings, despite increased availability of technology and telecommunication infrastructure. Methods A qualitative field study was conducted in four remote regions of Quebec (Canada) to explore perceptions of physicians and managers regarding the impact of telehealth on clinical practice and the organisation of health care services, as well as the conditions for improving telehealth implementation. A total of 54 respondents were interviewed either individually or in small groups. Content analysis of interviews was performed and identified several effects of telehealth on remote medical practice as well as key conditions to ensure the success of telehealth implementation. Results According to physicians and managers, telehealth benefits include better access to specialised services in remote regions, improved continuity of care, and increased availability of information. Telehealth also improves physicians' practice by facilitating continuing medical education, contacts with peers, and access to a second opinion. At the hospital and health region levels, telehealth has the potential to support the development of regional reference centres, favour retention of local expertise, and save costs. Conditions for successful implementation of telehealth networks include the participation of clinicians in decision-making, the availability of dedicated human and material resources, and a planned diffusion strategy. Interviews with physicians and managers also highlighted the importance of considering telehealth within the broader organisation of health care services in remote and rural regions. Conclusion This study identified core elements that should be considered when implementing telehealth applications with the purpose of supporting medical practice in rural and remote regions. Decision-makers need to be aware of the specific conditions that could influence telehealth integration into clinical practices and health care organisations. Thus, strategies addressing the identified conditions for telehealth success would facilitate the optimal implementation of this technology. PMID:16930484

Clinical Impact and Cellular Mechanisms of Iron Overload-Associated Bone Loss

PubMed Central

Jeney, Viktória

2017-01-01

Diseases/conditions with diverse etiology, such as hemoglobinopathies, hereditary hemochromatosis and menopause, could lead to chronic iron accumulation. This condition is frequently associated with a bone phenotype; characterized by low bone mass, osteoporosis/osteopenia, altered microarchitecture and biomechanics, and increased incidence of fractures. Osteoporotic bone phenotype constitutes a major complication in patients with iron overload. The purpose of this review is to summarize what we have learnt about iron overload-associated bone loss from clinical studies and animal models. Bone is a metabolically active tissue that undergoes continuous remodeling with the involvement of osteoclasts that resorb mineralized bone, and osteoblasts that form new bone. Growing evidence suggests that both increased bone resorption and decreased bone formation are involved in the pathological bone-loss in iron overload conditions. We will discuss the cellular and molecular mechanisms that are involved in this detrimental process. Fuller understanding of this complex mechanism may lead to the development of improved therapeutics meant to interrupt the pathologic effects of excess iron on bone. PMID:28270766

In 1991 the University of Wisconsin Hospital and Clinics formed a pain management QI team whose goal was to improve pain management through education, outcome monitoring, and the development of programs intended to improve clinical practice. Longitudinal monitoring mechanisms were established to audit medical records and survey patients to examine both staff practice patterns and patient outcomes. The QI team targeted use of meperidine, one of the most widely used opioid analgesics for the treatment of moderate to severe pain, which is now discouraged as a first-line agent for most painful conditions. A QI process was implemented using a traditional plan-do-check-act (PDCA) model, resulting in a successful and sustained reduction of inappropriate meperidine use. A cause-and-effect diagram helped highlight the multiple factors contributing to the drug's overuse and was used to prioritize targets for action. A flow chart helped to uncover some of the interrelationships between the myths about meperidine and the resultant customary prescribing and administration practices. While most of the strategies were implemented in 1996 (formulary guideline release, change in stock supply and physician orders, staff education and feedback), a significant impact in practice was not seen until late 1997. Ongoing tracking and feedback loops were established to ensure continued low use of meperidine. Use of a QI approach in pain management has been shown to affect the visibility of pain as a clinical priority, enhance interdisciplinary collaboration, facilitate the implementation of clinical guidelines at the bedside, and improve the quality of care for patients.

Theoretical considerations on the pathophysiology of normal pressure hydrocephalus (NPH) and NPH-related dementia.

Normal pressure hydrocephalus (NPH) is considered to be an example of reversible dementia although clinical improvement after shunting varies from subject to subject, and recent studies have pointed to a possible link with other dementia. The authors consider that the craniospinal compartment is a partially closed sphere with control device systems represented by the spinal axis and the sagittal sinus-arachnoid villi complex which interact with each other in the clinical patient setting. We hypothesise that changing spinal compliance by altering the flow process and CSF dynamics lead to hydrocephalus. Therefore four NPH types have been distinguished according to the alterations in spinal compliance, decrease in CSF absorption at the sagittal sinus or both occurrences. The authors consider that NPH and NPH-related diseases (NPH-RD) are initiated by the same common final pathway and demonstrate that NPH could represent an initial stage of NPH-RD. Progression of clinical signs can be explained as damage to the cerebral tissue by both intermittent increased intracranial pressure and pulse pressure waves leading to periventricular ischaemia. In addition, they believe that both volume equilibrium and spinal compliance are restored in patients who improve after CSF shunt, whereas in patients whose condition does not improve, only volume equilibrium is restored and not spinal compliance, which was the underlying cause of hydrocephalus in such cases. They therefore wonder whether cervical decompression should not be indicated in patients who show no improvement. Although attractive, this analysis warrants confirmation from clinical, radiological, and hydrodynamic studies.

This study aimed to assess the real-life clinical and virological outcomes of HCV waitlisted patients for liver transplantation (LT) who received sofosbuvir/ribavirin (SOF/R) within the Italian compassionate use program. Clinical and virological data were collected in 224 patients with decompensated cirrhosis and/or hepatocellular carcinoma (HCC) receiving daily SOF/R until LT or up a maximum of 48 weeks. Of 100 transplanted patients, 51 were HCV-RNA negative for >4 weeks before LT (SVR12: 88%) and 49 negative for <4 weeks or still viraemic at transplant: 34 patients continued treatment after LT (bridging therapy) (SVR12: 88%), while 15 stopped treatment (SVR12: 53%). 98 patients completed SOF/R without LT (SVR12: 73%). In patients with advanced decompensated cirrhosis (basal MELD ≥15 and/or C-P ≥B8), a marked improvement of the scores occurred in about 50% of cases and almost 20% of decompensated patients without HCC reached a condition suitable for inactivation and delisting. These real-life data indicate that in waitlisted patients: (i) bridging antiviral therapy can be an option for patients still viraemic or negative <4 weeks at LT; and (ii) clinical improvement to a condition suitable for delisting can occur even in patients with advanced decompensated cirrhosis. © 2017 John Wiley & Sons A/S.

Abstract With advanced technologies in hand, there exist potential applications and services built around monitoring activities of daily living (ADL) of elderly people at nursing homes. Most of the elderly people in these facilities are suffering from different chronic diseases such as dementia. Existing technologies are mainly focusing on non-medication interventions and monitoring of ADL for addressing loss of autonomy or well-being. Monitoring and managing ADL related to cognitive behaviors for non-medication intervention are very effective in improving dementia patients' conditions. However, cognitive functions of patients can be improved if appropriate recommendations of medications are delivered at a particular time. Previously we developed the Secured Wireless Sensor Network Integrated Cloud Computing for Ubiquitous-Life Care (SC3). SC3 services were limited to monitoring ADL of elderly people with Alzheimer's disease and providing non-medication recommendations to the patient. In this article, we propose a system called the Smart Clinical Decision Support System (CDSS) as an integral part of the SC3 platform. Using the Smart CDSS, patients are provided with access to medication recommendations of expert physicians. Physicians are provided with an interface to create clinical knowledge for medication recommendations and to observe the patient's condition. The clinical knowledge created by physicians as the knowledge base of the Smart CDSS produces recommendations to the caregiver for medications based on each patient's symptoms. PMID:25559934

The precise effect and the quality of different cases used in dermatology problem-based learning (PBL) curricula are yet unclear. To prospectively compare the impact of real patients, digital, paper PBL (PPBL) and traditional lecture-based learning (LBL) on academic results and student perceptions. A total of 120 students were randomly allocated into either real-patients PBL (RPBL) group studied via real-patient cases, digital PBL (DPBL) group studied via digital-form cases, PPBL group studied via paper-form cases, or conventional group who received didactic lectures. Academic results were assessed through review of written examination, objective structured clinical examination and student performance scores. A five-point Likert scale questionnaire was used to evaluate student perceptions. Compared to those receiving lectures only, all PBL participants had better results for written examination, clinical examination and overall performance. Students in RPBL group exhibited better overall performance than those in the other two PBL groups. Real-patient cases were more effective in helping develop students' self-directed learning skills, improving their confidence in future patient encounters and encouraging them to learn more about the discussed condition, compared to digital and paper cases. Both real patient and digital triggers are helpful in improving students' clinical problem-handling skills. However, real patients provide greater benefits to students.

Nursing students go through clinical supervision in primary health care settings but district nurses' (DNs) circumstances when supervising them are only briefly described in the literature. The aim of this study was to investigate DNs experience of supervising nursing students before and after the implementation of a new supervision model. Ninety-eight (74%) DNs answered a questionnaire before and 84 (65%) after implementation of the new supervision model. The study showed that DNs in most cases felt that conditions for supervision in the workplace were adequate. But about 70% lacked training for the supervisory role and 20% had no specialist district nurse training. They also experienced difficulty in keeping up-to-date with changes in nurse education programmes, in receiving support from the university and from their clinic managers, and in setting aside time for supervision. Improvements after the implementation of a new model chiefly concerned organisation; more DNs stated that one person had primary responsibility for students' clinical practice, that information packages for supervisors and students were available at the health care centres, and that conditions were in place for increasing the number of students they supervised. DNs also stated that supervisors and students benefited from supervision by more than one supervisor. To conclude, implementation of a new supervision model resulted in some improvements.

Lack of knowledge and negative attitudes have been identified as barriers to participation in clinical trials by patients with cancer. We developed Preparatory Education About Clinical Trials (PRE-ACT), a theory-guided, Web-based, interactive computer program, to deliver tailored video educational content to patients in an effort to overcome barriers to considering clinical trials as a treatment option. A prospective, randomized clinical trial compared PRE-ACT with a control condition that provided general clinical trials information produced by the National Cancer Institute (NCI) in text format. One thousand two hundred fifty-five patients with cancer were randomly allocated before their initial visit with an oncologist to PRE-ACT (n = 623) or control (n = 632). PRE-ACT had three main components: assessment of clinical trials knowledge and attitudinal barriers, values assessment with clarification back to patients, and provision of a video library tailored to address each patient's barriers. Outcomes included knowledge and attitudes and preparation for decision making about clinical trials. Both PRE-ACT and control interventions improved knowledge and attitudes (all P < .001) compared with baseline. Patients randomly allocated to PRE-ACT showed a significantly greater increase in knowledge (P < .001) and a significantly greater decrease in attitudinal barriers (P < .001) than did their control (text-only) counterparts. Participants in both arms significantly increased their preparedness to consider clinical trials (P < .001), and there was a trend favoring the PRE-ACT group (P < .09). PRE-ACT was also associated with greater patient satisfaction than was NCI text alone. These data show that patient education before the first oncologist visit improves knowledge, attitudes, and preparation for decision making about clinical trials. Both text and tailored video were effective. The PRE-ACT interactive video program was more effective than NCI text in improving knowledge and reducing attitudinal barriers. © 2015 by American Society of Clinical Oncology.

Current and future perspectives on the management of polypharmacy.

PubMed

Molokhia, Mariam; Majeed, Azeem

2017-06-06

Because of ageing populations, the growth in the number of people with multi-morbidity and greater compliance with disease-specific guidelines, polypharmacy is becoming increasingly common. Although the correct drug treatment in patients with complex medical problems can improve clinical outcomes, quality of life and life expectancy, polypharmacy is also associated with an increased risk of adverse drug events, some severe enough to result in hospital admission and even death. Hence, having systems in place to ensure that medications are started only when there is a suitable indication, ensuring patients are fully aware of the benefits and complications that may arise from their treatment, and reviewing patients regularly to ensure their medication regime remains appropriate, are essential. The development and rapid uptake of electronic patient records - particularly in primary care settings where the majority of prescribing takes place - makes monitoring of patients more straightforward than in the past; and allows identification of sub-groups of patients at particularly high risk of adverse drug events and complications. It also facilitates 'deprescribing' the process by which medications are reviewed and stopped if not clinically beneficial. In recent years, we have also seen the development of smartphone 'apps' to improve communication between patients and healthcare professionals, improve people's understanding of their conditions and their treatment, and maintain a record of changes made to patient's medication. In the longer term, developments such as the introduction of artificial intelligence and clinical decision support systems also have the potential to improve prescribing and minimise the risks from polypharmacy. Finally, there is considerable scope to improve the quality of prescribing and reduce risks from poly-pharmacy using non-medical groups such as pharmacists, specialist nurses and physician assistants. Polypharmacy has increased in recent decades and will continue to increase as populations age and the number of people with multiple long-term conditions increases. As with all areas of medicine, the evidence-base in this area continues to evolve. Further trials on the impact on patients with polypharmacy of new interventions such as technology-based solutions and the use of different professional groups are needed to improve the evidence-base in this area.

Structured review: evaluating the effectiveness of nurse case managers in improving health outcomes in three major chronic diseases.

This paper presents the findings of a review and appraisal of the evidence for the effectiveness of nurse case management in improving health outcomes for patients living either with Diabetes, Chronic Obstructive Pulmonary Disease or Coronary Heart Disease. Long term chronic health conditions provide some of the greatest challenges to western health care systems. In the UK, three of the most significant chronic conditions are Diabetes, Chronic Obstructive Pulmonary Disease and Coronary Heart Disease. Patients with these long term conditions are high users of health services who often receive unplanned, poorly co-ordinated, ad-hoc care in response to an exacerbation or crisis. To counter this, the nurse case manager is identified as a central aspect of improving care for these patients. However, the evidence for the effectiveness of nurse case management in improving health outcomes for the chronically ill is scarce. A structured review of the literature. The review was undertaken focussing on studies that evaluated nurse case management with one or all of the three major long term chronic conditions. A total of 108 papers were initially reviewed and filtered to leave 75 citations that were appraised. About 18 papers were finally included in the review and subject to thematic analysis based on the health outcomes evaluated in the studies. Significantly positive results were reported for nurse case management impact on five health outcomes; 'objective clinical measurements', 'quality of life and functionality', 'patient satisfaction', 'adherence to treatment' and 'self care and service use'. The evidence generated in this review suggests that nurse case managers have the potential to achieve improved health outcomes for patients with long term conditions. Further research is required to support role development and create a more targeted approach to the intervention.

Poor enrollment plagues most clinical trials. Furthermore, despite mandates to improve minority representation in clinical trial participation, little progress has been made. We investigated the knowledge and attitudes of adolescents related to clinical trials and made race/ethnicity comparisons in an attempt to identify a possible educational intervention target. Students aged 13-18 years in southeast Michigan were offered participation through a class at one high school or two academic summer enrichment programs that drew from multiple high schools (73% response). Questionnaires previously validated in adults were administered. Non-Hispanic whites were compared with minorities using Wilcoxon rank-sum tests. Of the 82 respondents, the median age was 16 years (interquartile range: 15-17 years); 22 (28%) were white, 41 (51%) were African American, 11 (14%) were multiracial, 2 (2%) were American Indian or Alaska Native, 1 (1%) was Asian, 3 (4%) were Native Hawaiian or other Pacific Islander, and 2 respondents did not report a race (but did report Hispanic ethnicity). Nine (12%) were Hispanic. Only 27 (33%) had ever heard of a clinical trial. On a scale from 1 (most receptive) to 5 (least receptive) for learning more about a clinical trial for a relevant medical condition, the median score was 2 (interquartile range: 1-3) and for participating in a clinical trial for a relevant medical condition was 2 (interquartile range: 2-3). Overall knowledge was poor, with a median of 46% (interquartile range: 23%-62%) of knowledge answers correct. Knowledge was reduced (p = 0.0006) and attitudes were more negative (p = 0.05) in minorities than non-Hispanic whites, while minorities also endorsed more substantial barriers to trial participation (p = 0.0002). Distrust was similar between minority students and non-Hispanic whites (p = 0.15), and self-efficacy was greater in non-Hispanic whites (p = 0.05). Educational interventions directed toward adolescents that address knowledge, attitudes, and distrust in order to improve clinical trial awareness and receptivity overall are needed and may represent a tool to address disparities in minority enrollment in clinical trials. © The Author(s) 2015.

Cancer biomarker discovery is improved by accounting for variability in general levels of drug sensitivity in pre-clinical models.

PubMed

Geeleher, Paul; Cox, Nancy J; Huang, R Stephanie

2016-09-21

We show that variability in general levels of drug sensitivity in pre-clinical cancer models confounds biomarker discovery. However, using a very large panel of cell lines, each treated with many drugs, we could estimate a general level of sensitivity to all drugs in each cell line. By conditioning on this variable, biomarkers were identified that were more likely to be effective in clinical trials than those identified using a conventional uncorrected approach. We find that differences in general levels of drug sensitivity are driven by biologically relevant processes. We developed a gene expression based method that can be used to correct for this confounder in future studies.

Human milk analyzers can measure macronutrient content in native breast milk to tailor adequate supplementation with fortifiers. This article reviews all studies using milk analyzers, including (i) evaluation of devices, (ii) the impact of different conditions on the macronutrient analysis of human milk, and (iii) clinical trials to improve growth. Results lack consistency, potentially due to systematic errors in the validation of the device, or pre-analytical sample preparation errors like homogenization. It is crucial to introduce good laboratory and clinical practice when using these devices; otherwise a non-validated clinical usage can severely affect growth outcomes of infants.

Hereditary arrhythmias and cardiomyopathies: decision-making about genetic testing.

2018-01-01

The modern field of clinical genetics has advanced beyond the traditional teachings familiar to most practicing cardiologists. Increased understanding of the roles of genetic testing may improve uptake and appropriateness of use. Clinical genetics has become integral to the management of patients with hereditary arrhythmia and cardiomyopathy diagnoses. Depending on the condition, genetic testing may be useful for diagnosis, prognosis, treatment, family screening, and reproductive planning. However, genetic testing is a powerful tool with potential for underuse, overuse, and misuse. In the absence of a substantial body of literature on how these guidelines are applied in clinical practice, we use a case-based approach to highlight key lessons and pitfalls. Importantly, in many scenarios genetic testing has become the standard of care supported by numerous class I recommendations; genetic counselors can improve accessibility to and appropriate use and application of testing. Optimal management of hereditary arrhythmias and cardiomyopathies incorporates genetic testing, applied as per consensus guidelines, with involvement of a multidisciplinary team.

A 79-year-old man, with a history of well-controlled diabetes mellitus, presented with left-sided otalgia. With an initial diagnosis of simple otitis externa, he was discharged on topical drops. He represented 2 months later with worsening otalgia and discharge. A diagnosis of malignant otitis externa was made based on clinical and radiological findings. Intravenous Tazocin and Gentamicin were given based on previous bacterial culture from ear swabs. The patient failed to improve and developed left-sided facial nerve palsy. His condition stabilised following a change in antimicrobial therapy and his management continued in the community on intravenous Meropenem with twice weekly aural toilet. Repeated nuclear medicine imaging failed to demonstrate resolution. A bony sequestration was removed from the external auditory canal in the outpatient clinic, which following extended culture grew Scedosporium apiospermum; his management was subsequently changed to oral Voriconazole. This led to rapid clinical improvement and disease resolution over a 6 -week period. 2016 BMJ Publishing Group Ltd.

To investigate the clinical assessment of a full high-definition (HD) three-dimensional robot-assisted laparoscopic device in gynaecological surgery. This study included 70 women who underwent gynaecological laparoscopic procedures. Demographic parameters, type and duration of surgery and perioperative complications were analyzed. Fifteen surgeons were postoperatively interviewed regarding their assessment of this new system with a standardized questionnaire. The clinical assessment revealed that three-dimensional full-HD visualisation is comfortable and improves spatial orientation and hand-to-eye coordination. The majority of the surgeons stated they would prefer a three-dimensional system to a conventional two-dimensional device and stated that the robotic camera arm led to more relaxed working conditions. Three-dimensional laparoscopy is feasible, comfortable and well-accepted in daily routine. The three-dimensional visualisation improves surgeons' hand-to-eye coordination, intracorporeal suturing and fine dissection. The combination of full-HD three-dimensional visualisation with the robotic camera arm results in very high image quality and stability.

Biopharmaceutical considerations and characterizations in development of colon targeted dosage forms for inflammatory bowel disease.

Colon targeted dosage forms have been extensively studied for the localized treatment of inflammatory bowel disease. These dosage forms not only improve the therapeutic efficacy but also reduce the incidence of adverse drug reactions and hence improve the patient compliance. However, complex and highly variable gastro intestinal physiology limits the clinical success of these dosage forms. Biopharmaceutical characteristics of these dosage forms play a key role in rapid formulation development and ensure the clinical success. The complexity in product development and clinical success of colon targeted dosage forms are based on the biopharmaceutical characteristics such as physicochemical properties of drug substances, pharmaceutical characteristics of dosage form, physiological conditions and pharmacokinetic properties of drug substances as well as drug products. Various in vitro and in vivo techniques have been employed in past to characterize the biopharmaceutical properties of colon targeted dosage forms. This review focuses on the factors influencing the biopharmaceutical performances of the dosage forms, in vitro characterization techniques and in vivo studies.

Spinal cord injury (SCI) is a devastating condition that affects many people worldwide. Treatment focuses on controlling secondary injury cascade and improving regeneration. It has recently been suggested that both the secondary injury cascade and the regenerative process are heavily regulated by microRNAs (miRNAs). The measurement of specific biomarkers could improve our understanding of the disease processes, and thereby provide clinicians with the opportunity to guide treatment and predict clinical outcomes after SCI. A variety of miRNAs exhibit important roles in processes of inflammation, cell death, and regeneration. These miRNAs can be used as diagnostic tools for predicting outcome after SCI. In addition, miRNAs can be used in the treatment of SCI and its symptoms. Significant laboratory and clinical evidence exist to show that miRNAs could be used as robust diagnostic and therapeutic tools for the treatment of patients with SCI. Further clinical studies are warranted to clarify the importance of each subtype of miRNA in SCI management.

Project Extension for Community Healthcare Outcomes (Project ECHO) is a telemedicine and distance-learning program designed to improve access to quality health care for New Mexicans with hepatitis C. Project ECHO links health-care providers from rural clinics, the Indian Health Service, and prisons with specialists at the University of New Mexico. At weekly clinics, partners present and discuss patients with hepatitis C with specialists. Partners can receive continuing education credits for participating. Since June 2003, 173 hepatitis C clinics have been conducted with 1,843 case presentations. Partners have received 390 hours of training and 2,997 hours of continuing education credits. And in 2006, the State Legislature approved $1.5 million in annual funding for the project. Project ECHO has increased access to state-of-the art hepatitis C virus care for patients living in rural areas or prisons. Because of its success with hepatitis C, this project is being expanded to other chronic medical conditions.

Concurrent epidemics of HIV, depression, alcohol abuse, and partner violence threaten maternal and child health (MCH) in South Africa. Although home visiting has been repeatedly demonstrated efficacious in research evaluations, efficacy disappears when programs are scaled broadly. In this cluster randomized controlled trial (RCT), we examine whether the benefits of ongoing accountability and supervision within an existing government funded and implemented community health workers (CHW) home visiting program ensure the effectiveness of home visiting. In the deeply rural, Eastern Cape of South Africa, CHW will be hired by the government and will be initially trained by the Philani Programme to conduct home visits with all pregnant mothers and their children until the children are 2 years old. Eight clinics will be randomized to receive either (1) the Accountable Care Condition in which additional monitoring and accountability systems that Philani routinely uses are implemented (4 clinics, 16 CHW, 450 households); or (2) a Standard Care Condition of initial Philani training, but with supervision and monitoring being delivered by local government structures and systems (4 clinics, 21 CHW, 450 households). In the Accountable Care Condition areas, the CHW's mobile phone reports, which are time-location stamped, will be monitored and data-informed supervision will be provided, as well as monitoring growth, medical adherence, mental health, and alcohol use outcomes. Interviewers will independently assess outcomes at pregnancy at 3, 6, 15, and 24 months post-birth. The primary outcome will be a composite score of documenting maternal HIV/TB testing, linkage to care, treatment adherence and retention, as well as child physical growth, cognitive functioning, and child behavior and developmental milestones. The proposed cluster RCT will evaluate whether routinely implementing supervision and accountability procedures and monitoring CHWs' over time will improve MCH outcomes over the first 2 years of life.

False dichotomies: EBM, clinical freedom, and the art of medicine.

PubMed

Parker, M

2005-06-01

According to numerous commentators, clinical freedom, the art of medicine, and, by implication, a degree of patient welfare, are threatened by evidence based medicine (EBM). As EBM has developed over the last fifteen years, claims about better evidence for medical treatments, and improvements in healthcare delivery, have been matched by critiques of EBM's reductionism and uniformity, its problematic application to individual patients, and its alleged denial of the continuing need for clinical interpretation, insight, and judgment. Most of these attacks on EBM and defences of clinical freedom fail. They are based on erroneous understandings of the relationships between inductive knowledge, clinical uncertainty, and action. Evidence based medicine is a necessary condition for clinical freedom, not a threat to it, and EBM is not something to be balanced with either clinical experience or patient preferences. The art and science of medicine are more conceptually and practically connected than the defenders of clinical freedom, whatever they conceive that to be, are willing to admit.

Introduction Dolutegravir is a second generation integrase inhibitor with a proposed high genetic barrier to resistance. However, in clinical trials, decreased virological response was seen in a subset of patients with prior exposure to raltegravir and multiple integrase resistance mutations. Methods We describe two cases of HIV subtype B-infected patients starting dolutegravir after previous failure on a raltegravir-containing regimen with extensive resistance. Genotypic analysis was performed using population sequencing and 454 ultradeep sequencing of integrase at time of raltegravir exposure. Results Both patients were diagnosed in early 1990s and received mono- and dual therapy, followed by several cART-regimens. Due to presence of extensive resistance, the genotypic susceptibility score of these regimens never reached a score >2 and never resulted in sustained virological suppression despite good adherence. Early 2012, the clinical condition of patient 1 worsened during persistent failure of a mega-cART regimen despite excellent drug levels. Six major PI, six minor PI, seven NRTI, six NNRTI and two INI mutations plus DM-virus were detected (Table 1). Ultra-deep sequencing of integrase showed the selection of Q148R, E138K+Q148K, and N155H variants and phenotypic raltegravir resistance was demonstrated. After addition of dolutegravir and enfuvirtide to the failing regimen (zidovudine, lamivudine, tenofovir, etravirine, darunavir/ritonavir, maraviroc), viral load (VL) decreased from 244,000 to <20 cps/mL within five months, CD4-count increased (33 to 272 mm3) and the clinical condition improved substantially. In patient 2, similar worsening of the clinical condition was observed late 2012 during persistent failure on mega-cART. Five major PI, six minor PI, nine NRTI, seven NNRTI and one INI mutation plus DM-virus were detected. Ultra-deep sequencing showed selection of N155H, followed by Q95K and V151I variants and phenotypic raltegravir resistance was demonstrated. Dolutegravir was added to his failing regimen (zidovudine, lamivudine, etravirine, atazanavir/ritonavir, maraviroc) at a VL of 39,000 cps/mL. Sustained virological suppression was reached within five months with considerable increase of CD4-count (41 to 175 mm3) and slight improvement of clinical condition. Conclusions We present the first patients with extensive integrase resistance who were treated with dolutegravir in clinical practice and who achieved excellent virological and immunological success. These cases demonstrate the high genetic barrier of dolutegravir. PMID:25397500

This study evaluated The Transporters, an animated series designed to enhance emotion comprehension in children with autism spectrum conditions (ASC). n = 20 children with ASC (aged 4-7) watched The Transporters everyday for 4 weeks. Participants were tested before and after intervention on emotional vocabulary and emotion recognition at three levels of generalization. Two matched control groups of children (ASC group, n = 18 and typically developing group, n = 18) were also assessed twice without any intervention. The intervention group improved significantly more than the clinical control group on all task levels, performing comparably to typical controls at Time 2. We conclude that using The Transporters significantly improves emotion recognition in children with ASC. Future research should evaluate the series' effectiveness with lower-functioning individuals.

New healthcare delivery models are needed to enhance the patient experience and improve quality of care for individuals with chronic conditions such as kidney disease. One potential avenue is to implement self-management strategies. There is growing evidence that self-management interventions help optimize various aspects of chronic disease management. With the increasing use of information technology (IT) in health care, chronic disease management programs are incorporating IT solutions to support patient self-management practices. IT solutions have the ability to promote key principles of self-management, namely education, empowerment, and collaboration. Positive clinical outcomes have been demonstrated for a number of chronic conditions when IT solutions were incorporated into self-management programs. There is a paucity of evidence for self-management in chronic kidney disease (CKD) patients. Furthermore, IT strategies have not been tested in this patient population to the same extent as other chronic conditions (e.g., diabetes, hypertension). Therefore, it is currently unknown if IT strategies will promote self-management behaviors and lead to improvements in overall patient care. We designed and developed an IT solution called My KidneyCare Centre to support self-management strategies for patients with CKD. In this review, we discuss the rationale and vision of incorporating an electronic self-management tool to support the care of patients with CKD. © 2013 Wiley Periodicals, Inc.

The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery. © 2015 Wiley Publishing Asia Pty Ltd.

Cherubism is a rare, autosomal dominant, mostly self-limiting disease of the jaw. It is characterized by bilateral fibrous tissue hyperplasia, giant cell proliferation, and bony degeneration in the lower facial skeleton, which can result in a massive and severely deforming prominence of the maxillomandibular structure. This case study examines the multidisciplinary management of a severe case of cherubism complicated by neurofibromatosis type 1, 2 codominant nonsegregating conditions that were clinically and genetically diagnosed, an extremely rare combination. Adequate mandibular reduction, reconstruction, and dental implantation afforded good restoration of oral function as well as a marked aesthetic improvement. A 14-year-old Fijian girl was referred to our unit for management of severe overgrowth of her mandible that compromised her speech and deglutition. In addition, she displayed clinical features consistent with neurofibromatosis type 1. Radiologic, histologic, and genetic analyses confirmed the diagnosis of both conditions. Our craniofacial multidisciplinary team undertook mandibular reconstruction followed by placement of osseointegrated dental implants. Mandibular reduction, reconstruction, and dental implantation resulted in a significantly improved functional and aesthetic outcome with no further regrowth at 3-year follow-up when she returned to the United Kingdom for osseointegrated dental implant insertion. The successful outcome of this surgically challenging, grossly disfiguring, and rare condition was largely a result of the combined input from our multidisciplinary team, adequate preoperative planning, and the use of a novel surgical technique in debulking and reconstructing her mandible.

Management of the elderly patient with AL amyloidosis.

Systemic immunoglobulin light chain (AL) amyloidosis is an aging-associated protein misfolding and deposition disease. This condition is caused by a small and otherwise indolent plasma cell (or B cell) clone secreting an unstable circulating light chain, which misfolds and deposits as amyloid fibrils possibly leading to progressive dysfunction of affected organs. AL amyloidosis can occur in the typical setting of other, rarer forms of systemic amyloidosis and can mimic other more prevalent conditions of the elderly. Therefore, its diagnosis requires a high degree of clinical suspicion and reliable diagnostic tools for accurate amyloid typing, available at specialized referral centers. In AL amyloidosis, frailty is dictated by the type and severity of organ involvement, with heart involvement being the main determinant of morbidity and mortality. Still, given a similar disease stage, elderly patients with AL amyloidosis are often an even frailer group, due to significant comorbidities, associated disability and polypharmacotherapy, socioeconomic restrictions, and limited access to clinical trials. Recent improvements in the use of biomarkers for early diagnosis, risk stratification and response monitoring, the flourishing of novel, effective anti-plasma cell therapies developed against multiple myeloma and adapted to treat AL amyloidosis, and possibly the introduction of anti-amyloid therapies are rapidly changing the clinical management of this disease and are reflected by improved outcomes. Of note, hematologic and organ responses in elderly patients with AL amyloidosis do translate in better outcome, advocating the importance of treating these patients and striving for a rapid response to therapy also in this challenging clinical setting.

Long-term prescription of N-acetyl cysteine (NAC) may be effective in diseases caused by active radicals of oxygen species. The aim of this study was to determine the effect of 2- and 4-month administration of NAC (1800 mg daily) on mustard induced bronchiolitis obliterans. In a double blind clinical trial, 144 patients with bronchiolitis obliterans due to sulfur mustard in bronchiolitis obliterans syndrome (BOS) classes 1 and 2, randomly entered Group 1 (n=72, NAC) and Group 2 (n=72, placebo). Dyspnea, wake-up dyspnea, cough, and sputum were measured after 4 months. Spirometric findings were measured at the beginning of the trial, 2 months after and after 4 months of prescription of 1800 mg/day in three doses of NAC or placebo. Dyspnea, cough, sputum, and wake-up dyspnea improved after 4 months of NAC compared to the control group. After 4 months, spirometric components were significantly improved in NAC group compared to placebo group. Fourth months administration of NAC (1800 mg daily) can improve clinical conditions and spirometric findings in mustard exposed in BOS class 1 or 2.

Methods to Improve Osseointegration of Dental Implants in Low Quality (Type-IV) Bone: An Overview.

PubMed

Alghamdi, Hamdan S

2018-01-13

Nowadays, dental implants have become more common treatment for replacing missing teeth and aim to improve chewing efficiency, physical health, and esthetics. The favorable clinical performance of dental implants has been attributed to their firm osseointegration, as introduced by Brånemark in 1965. Although the survival rate of dental implants over a 10-year observation has been reported to be higher than 90% in totally edentulous jaws, the clinical outcome of implant treatment is challenged in compromised (bone) conditions, as are frequently present in elderly people. The biomechanical characteristics of bone in aged patients do not offer proper stability to implants, being similar to type-IV bone (Lekholm & Zarb classification), in which a decreased clinical fixation of implants has been clearly demonstrated. However, the search for improved osseointegration has continued forward for the new evolution of modern dental implants. This represents a continuum of developments spanning more than 20 years of research on implant related-factors including surgical techniques, implant design, and surface properties. The methods to enhance osseointegration of dental implants in low quality (type-IV) bone are described in a general manner in this review.

To investigate the clinical effect of Saccharomyces boulardii powder combined with azithromycin sequential therapy in the treatment of children with diarrhea secondary to Mycoplasma pneumoniae pneumonia. A total of 88 children with diarrhea secondary to Mycoplasma pneumoniae pneumonia between June 2015 and March 2017 were divided into control group and study group using a random number table, with 44 children in each group. The children in the control group were given routine treatment combined with azithromycin sequential therapy, and those in the study group were given oral Saccharomyces boulardii powder in addition to the treatment in the control group until the end of azithromycin sequential therapy. After the treatment ended, the two groups were compared in terms of time to improvement of clinical symptoms, length of hospital stay, clinical outcome, defecation frequency before and after treatment, condition of intestinal dysbacteriosis, and incidence of adverse events. Compared with the control group, the study group had significantly shorter time to improvement of clinical symptoms and length of hospital stay (P<0.05). The study group had a significantly higher response rate than the control group (P<0.05). On days 3 and 5 of treatment, the study group had a significant reduction in defecation frequency compared with the control group (P<0.05). The study group had a significantly lower rate of intestinal dysbacteriosis than the control group (P<0.05). There was no significant difference in the incidence of adverse events between the two groups (P>0.05). In the treatment of children with diarrhea secondary to Mycoplasma pneumoniae pneumonia, Saccharomyces boulardii powder combined with azithromycin sequential therapy can improve clinical symptoms, shorten the length of hospital stay, reduce defecation frequency and the incidence of intestinal dysbacteriosis, and improve clinical outcomes, and does not increase the risk of adverse events.

A large and compelling clinical evidence base has shown that integrated TB and HIV services leads to reduction in human immunodeficiency virus (HIV)- and tuberculosis (TB)-associated mortality and morbidity. Despite official policies and guidelines recommending TB and HIV care integration, its poor implementation has resulted in TB and HIV remaining the commonest causes of death in several countries in sub-Saharan Africa, including South Africa. This study aims to reduce mortality due to TB-HIV co-infection through a quality improvement strategy for scaling up of TB and HIV treatment integration in rural primary healthcare clinics in South Africa. The study is designed as an open-label cluster randomized controlled trial. Sixteen clinic supervisors who oversee 40 primary health care (PHC) clinics in two rural districts of KwaZulu-Natal, South Africa will be randomized to either the control group (provision of standard government guidance for TB-HIV integration) or the intervention group (provision of standard government guidance with active enhancement of TB-HIV care integration through a quality improvement approach). The primary outcome is all-cause mortality among TB-HIV patients. Secondary outcomes include time to antiretroviral therapy (ART) initiation among TB-HIV co-infected patients, as well as TB and HIV treatment outcomes at 12 months. In addition, factors that may affect the intervention, such as conditions in the clinic and staff availability, will be closely monitored and documented. This study has the potential to address the gap between the establishment of TB-HIV care integration policies and guidelines and their implementation in the provision of integrated care in PHC clinics. If successful, an evidence-based intervention comprising change ideas, tools, and approaches for quality improvement could inform the future rapid scale up, implementation, and sustainability of improved TB-HIV integration across sub-Sahara Africa and other resource-constrained settings.

Immunotherapy based on checkpoint blockers has proven survival benefits in patients with melanoma and other malignancies. Nevertheless, a significant proportion of treated patients remains refractory, suggesting that in combination with active immunizations, such as cancer vaccines, they could be helpful to improve response rates. During the last decade, we have used dendritic cell (DC) based vaccines where DCs loaded with an allogeneic heat-conditioned melanoma cell lysate were tested in a series of clinical trials. In these studies, 60% of stage IV melanoma DC-treated patients showed immunological responses correlating with improved survival. Further studies showed that an essential part of the clinical efficacy was associated with the use of conditioned lysates. Gallbladder cancer (GBC) is a high-incidence malignancy in South America. Here, we evaluated the feasibility of producing effective DCs using heat-conditioned cell lysates derived from gallbladder cancer cell lines (GBCCL). By characterizing nine different GBCCLs and several fresh tumor tissues, we found that they expressed some tumor-associated antigens such as CEA, MUC-1, CA19-9, Erb2, Survivin, and several carcinoembryonic antigens. Moreover, heat-shock treatment of GBCCLs induced calreticulin translocation and release of HMGB1 and ATP, both known to act as danger signals. Monocytes stimulated with combinations of conditioned lysates exhibited a potent increase of DC-maturation markers. Furthermore, conditioned lysate-matured DCs were capable of strongly inducing CD4 + and CD8 + T cell activation, in both allogeneic and autologous cell co-cultures. Finally, in vitro stimulated CD8 + T cells recognize HLA-matched GBCCLs. In summary, GBC cell lysate-loaded DCs may be considered for future immunotherapy approaches.

Objective Identifying treatments to improve functioning and reduce negative symptoms in consumers with schizophrenia is of high public health significance. Method In this randomized clinical trial, participants with schizophrenia or schizoaffective disorder (N=149) were randomly assigned to cognitive behavioral social skills training (CBSST) or an active goal-focused supportive contact (GFSC) control condition. CBSST combined cognitive behavior therapy with social skills training and problem solving training to improve functioning and negative symptoms. GFSC was weekly supportive group therapy focused on setting and achieving functioning goals. Blind raters assessed functioning (primary outcome: Independent Living Skills Survey (ILSS)), CBSST skill knowledge, positive and negative symptoms, depression, and defeatist performance attitudes. Results In mixed-effects regression models in intent-to-treat analyses, CBSST skill knowledge, functioning, amotivation/asociality negative symptoms and defeatist performance attitudes improved significantly more in CBSST relative to GFSC. In both treatment groups, comparable improvements were also found for positive symptoms and a performance-based measure of social competence. Conclusions The results suggest CBSST is an effective treatment to improve functioning and experiential negative symptoms in consumers with schizophrenia, and both CBSST and supportive group therapy that is actively focused on setting and achieving functioning goals can improve social competence and reduce positive symptoms.

Patient-reported outcome (PRO) refers to measures that emphasize the subjective view of patients about their health-related conditions and behaviors. Typically, PROs include self-report questionnaires and clinical interviews. Defining PROs for borderline personality disorder (BPD) is particularly challenging given the disorder's high symptomatic heterogeneity, high comorbidity with other psychiatric conditions, highly fluctuating symptoms, weak correlations between symptoms and functional outcomes, and lack of valid and reliable experimental measures to complement self-report data. Here, we provide an overview of currently used BPD outcome measures and discuss them from clinical, psychometric, experimental, and patient perspectives. In addition, we review the most promising leads to improve BPD PROs, including the DSM-5 Section III, the Recovery Approach, Ecological Momentary Assessments, and novel experimental measures of social functioning that are associated with functional and social outcomes.

Obesity is now a major international health concern. It is increasingly common in young women with reproductive, metabolic and psychological health impacts. Reproductive health impacts are often poorly appreciated and include polycystic ovary syndrome (PCOS), infertility and pregnancy complications. PCOS is the most common endocrine condition in women and is underpinned by hormonal disturbances including insulin resistance and hyperandrogenism. Obesity exacerbates hormonal and clinical features of PCOS and women with PCOS appear at higher risk of obesity, with multiple underlying mechanisms linking the conditions. Lifestyle intervention is first line in management of PCOS to both prevent weight gain and induce weight loss; however improved engagement and sustainability remain challenges with the need for more research. Medications like metformin, orlistat, GLP1 agonists and bariatric surgery have been used with the need for large scale randomised clinical trials to define their roles.

Towards a cognitive-learning formulation of youth anxiety: A narrative review of theory and evidence and implications for treatment.

Waters, Allison M; Craske, Michelle G

2016-12-01

The tendency to disproportionately allocate attention to threat stimuli, to evaluate ambiguous or benign situations as overly threatening, and to exhibit overgeneralised and indiscriminate conditioned fear responses to threat and safe stimuli are hallmark clinical correlates of pathological anxiety. Investigation of these processes in children and adolescents suggests that anxiety-related differences increase with age, and that the specific conditions under which anxious children differ from non-anxious peers are poorly understood. Furthermore, research on cognitive biases and fear conditioning in anxious children and adolescents has progressed as quite distinct lines of investigation. Greater integration of key tenets from each perspective could advance knowledge and provide new directions for improving treatments. The purpose of this paper is threefold. First, we provide a qualitative review of the key principles from cognitive and conditioning theories of anxiety and the associated empirical research, including the underlying neurophysiological basis of these processes in anxious children and adolescents, in order to delineate the conditions under which anxiety-specific differences in threat-related cognitive biases and overgeneralised conditioned fear manifest in children and adolescents. Second, we synthesize these theoretical and empirical insights to propose a cognitive-learning formulation of anxiety in children and adolescents. We propose that conditioning and cognitive factors linked to differences in engagement of underlying neural circuits across development contribute to an internal representation of a wide range of stimuli as threatening, to which anxious children and adolescents adopt maladaptive attention regulation patterns of predominantly threat monitoring or threat avoidance. These maladaptive attention regulation patterns differentiate anxious children and adolescents in terms of predominantly high cognitive distress (e.g., worry and rumination) and high behavioural avoidance respectively. Third, we consider the clinical implications of the cognitive-learning formulation for understanding outcomes from current treatments and provide suggestions for improving treatment outcomes.

To determine whether neurocognitive performance and clinical outcomes can be enhanced by a mindfulness intervention in older adults with stress disorders and cognitive complaints. To explore decreased hypothalamic-pituitary-adrenal (HPA) axis activity as a possible mechanism. 103 adults aged 65 years or older with an anxiety or depressive disorder (diagnosed according to DSM-IV criteria) and subjective neurocognitive difficulties were recruited in St. Louis, Missouri, or San Diego, California, from September 2012 through August 2013 and randomly assigned in groups of 5-8 to mindfulness-based stress reduction (MBSR) or a health education control condition matched for time, attention, and credibility. The primary outcomes were memory (assessed by immediate and delayed paragraph and list recall) and cognitive control (Delis-Kaplan Executive Function System Verbal Fluency Test and Color Word Interference Test). Other outcomes included clinical symptoms (worry, depression, anxiety, and global improvement). HPA axis activity was assessed using peak salivary cortisol. Outcomes were measured immediately post-intervention and (for clinical outcomes only) at 3- and 6-month follow up. On the basis of intent-to-treat principles using data from all 103 participants, the mindfulness group experienced greater improvement on a memory composite score (P = .046). Groups did not differ on change in cognitive control. Participants receiving MBSR also improved more on measures of worry (P = .042) and depression (P = .049) at posttreatment and on worry (P = .02), depression (P = .002), and anxiety (P = .002) at follow-up and were more likely to be rated as much or very much improved as rated by the Clinical Global Impressions-Improvement scale (47% vs 27%, χ² = 4.5, P = .03). Cortisol level decreased to a greater extent in the mindfulness group, but only among those participants with high baseline cortisol. In this population of older adults with stress disorders and neurocognitive difficulties, a mindfulness intervention improves clinical outcomes such as excessive worry and depression and may include some forms of immediate memory performance.

Pulse oximetry manufacturers have introduced technologies that claim improved detection of hypoxemic events. Because improvements in signal processing and data rejection algorithms may differentially affect data reporting, we compared the data reporting and signal heuristic performance and agreement among the Nellcor N-395, Masimo SET, and GE Solar 8000 oximeters under a spectrum of conditions of signal integrity and arterial oxygen saturations. A blinded side-by-side comparison of technologies was performed in 27 patients, and data were analyzed for time of data availability, measures of agreement and signal heuristics, and warnings stratified by signal integrity and SpO(2). The Solar 8000 had less total data dropout than either of the new technologies. Masimo's LoSIQ (signal quality) heuristic rejected less data than Nellcor's MOT/PS (motion/pulse search) flag. When no signal heuristic was displayed, there was little difference in precision and bias between the two newer technologies; however, agreement between devices deteriorated in the presence of SIQ, MOT, or hypoxemia. Both newer devices flagged questionable data, but their use of different rejection algorithms resulted in different probabilities of presenting data. Therefore, with poor SIQ or during hypoxemia, the Nellcor N-395 and Masimo oximeters are not clinically equivalent to each other or to the older Solar 8000 oximeter. We compared new pulse oximeters from Nellcor and Masimo and found that, with good signal conditions, both new devices performed similarly to older technology. Overall, Masimo reported less data as questionable than Nellcor. With poor signal conditions or during hypoxemia, the new devices are not clinically equivalent to each other or to the older technology.

Background The comorbidity of type 2 diabetes mellitus (T2DM) and depression is associated with poor glycemic control. Exercise has been shown to improve mood and glycemic control, but individuals with comorbid T2DM and depression are disproportionately sedentary compared to the general population and report more difficulty with exercise. Behavioral activation, an evidence-based depression psychotherapy, was designed to help people with depression make gradual behavior changes, and may be helpful to build exercise adherence in sedentary populations. This pilot randomized clinical trial will test the feasibility of a group exercise program enhanced with behavioral activation strategies among women with comorbid T2DM and depression. Methods/Design Sedentary women with inadequately controlled T2DM and depression (N=60) will be randomly assigned to one of two conditions: exercise or usual care. Participants randomized to the exercise condition will attend 38 behavioral activation-enhanced group exercise classes over 24 weeks in addition to usual care. Participants randomized to the usual care condition will receive depression treatment referrals and print information on diabetes management via diet and physical activity. Assessments will occur at baseline and 3-, 6-, and 9-months following randomization. The goals of this pilot study are to demonstrate feasibility and intervention acceptability, estimate the resources and costs required to deliver the intervention and to estimate the standard deviation of continuous outcomes (e.g., depressive symptoms and glycosylated hemoglobin) in preparation for a fully-powered randomized clinical trial. Discussion A novel intervention that combines exercise and behavioral activation strategies could potentially improve glycemic control and mood in women with comorbid type 2 diabetes and depression.

This investigation aimed to develop a scanner quantification performance methodology and compare multiple metrics between two scanners under different imaging conditions. Most PET scanners are designed to work over a wide dynamic range of patient imaging conditions. Clinical constraints, however, often impact the realization of the entitlement performance for a particular scanner design. Using less injected dose and imaging for a shorter time are often key considerations, all while maintaining "acceptable" image quality and quantitative capability. A dual phantom measurement including resolution inserts was used to measure the effects of in-plane (x, y) and axial (z) system resolution between two PET/CT systems with different block detector crystal dimensions. One of the scanners had significantly thinner slices. Several quantitative measures, including feature contrast recovery, max/min value, and feature profile accuracy were derived from the resulting data and compared between the two scanners and multiple phantoms and alignments. At the clinically relevant count levels used, the scanner with thinner slices had improved performance of approximately 2%, averaged over phantom alignments, measures, and reconstruction methods, for the head-sized phantom, mainly demonstrated with the rods aligned perpendicular to the scanner axis. That same scanner had a slightly decreased performance of -1% for the larger body-size phantom, mostly due to an apparent noise increase in the images. Most of the differences in the metrics between the two scanners were less than 10%. Using the proposed scanner performance methodology, it was shown that smaller detector elements and a larger number of image voxels require higher count density in order to demonstrate improved image quality and quantitation. In a body imaging scenario under typical clinical conditions, the potential advantages of the design must overcome increases in noise due to lower count density.

Drinking water is an important nutrient for human health. The mineral ingredients included in drinking water may affect the physical condition of people. Various kinds of natural water are in circulation as bottled water in developed countries; however, its influence on clinical conditions of patients with certain diseases has not been fully evaluated. In this study, effects of the natural groundwater from Jeju Island on clinical symptoms and skin barrier function in atopic dermatitis (AD) were evaluated. NC/Tnd mice, a model for human AD, with moderate to severe dermatitis were used. Mice were given different natural groundwater or tap water for 8 weeks from 4 weeks of age. Clinical skin severity scores were recorded every week. Scratching analysis and measurement of transepidermal water loss were performed every other week. The pathological condition of the dorsal skin was evaluated histologically. Real-time polymerase chain reaction analysis was performed for cytokine expression in the affected skin. The epidermal hyperplasia and allergic inflammation were reduced in atopic mice supplied with Jeju groundwater when compared to those supplied with tap water or other kinds of natural groundwater. The increase in scratching behavior with the aggravation of clinical severity of dermatitis was favorably controlled. Moreover, transepidermal water loss that reflects skin barrier function was recovered. The early inflammation and hypersensitivity in the atopic skin was alleviated in mice supplied with Jeju groundwater, suggesting its profitable potential on the daily care of patients with skin troubles including AD. © 2013 Japanese Dermatological Association.

Financial and in-kind incentives have been shown to improve outcomes along the HIV care cascade, however the potential mechanismsthrough which they work remain unclear. To identify the pathways through which incentives improve retention in care and adherence to antiretroviral therapy (ART), we conducted a qualitative study with participants in a trial evaluating conditional food and cash incentives for HIV-positive food insecure adults in Shinyanga, Tanzania. We found that the incentives acted through three pathways to potentially increase retention in care and adherence to ART: (1) addressing competing needs and offsetting opportunity costs associated with clinic attendance, (2) alleviating stress associated with attending clinic and meeting basic needs, and (3) by potentially increasing motivation. Participants did not report any harmful events associated with the incentives, but reported myriad beneficial effects on household welfare. Understanding how incentives are used and how they impact outcomes can improve the design of future interventions.

Hyaluronan (HA) has been increasingly used as a dietary supplement to improve the skin. However, the effect of ingested HA may depend on its molecular weight (MW) because its physiological activities in the body vary with its MW. In this study, we examined the effects of ingested HA with varying MW on the skin. In this randomized, double blind, placebo controlled study, 61 subjects with dry skin received oral HA (120 mg/day), of MWs 800 k and 300 k or placebo, for 6 weeks. The skin moisture contents of the first two groups increased more than those of the placebo group during the ingestion period. In addition, group HA 300 k exhibited significant improvements in skin moisture content 2 weeks after ingestion ended compared with the placebo group. A questionnaire survey about subjective facial aging symptoms showed that the HA treated groups exhibited significantly improved the skin condition compared with the placebo treated group. Furthermore, dermatologists objectively evaluated the clinical symptoms of the facial and whole body skin, showing that no adverse events were related to daily ingestion of HA. This study shows that both of ingesting HAs (MWs 800 k and 300 k) improved the skin condition by increasing the moisture content. PMID:25834304

Integration of an EEG biomarker with a clinician's ADHD evaluation

Background This study is the first to evaluate an assessment aid for attention-deficit/hyperactivity disorder (ADHD) according to both Class-I evidence standards of American Academy of Neurology and De Novo requirements of US Food and Drug Administration. The assessment aid involves a method to integrate an electroencephalographic (EEG) biomarker, theta/beta ratio (TBR), with a clinician's ADHD evaluation. The integration method is intended as a step to help improve certainty with criterion E (i.e., whether symptoms are better explained by another condition). Methods To evaluate the assessment aid, investigators conducted a prospective, triple-blinded, 13-site, clinical cohort study. Comprehensive clinical evaluation data were obtained from 275 children and adolescents presenting with attentional and behavioral concerns. A qualified clinician at each site performed differential diagnosis. EEG was collected by separate teams. The reference standard was consensus diagnosis by an independent, multidisciplinary team (psychiatrist, psychologist, and neurodevelopmental pediatrician), which is well-suited to evaluate criterion E in a complex clinical population. Results Of 209 patients meeting ADHD criteria per a site clinician's judgment, 93 were separately found by the multidisciplinary team to be less likely to meet criterion E, implying possible overdiagnosis by clinicians in 34% of the total clinical sample (93/275). Of those 93, 91% were also identified by EEG, showing a relatively lower TBR (85/93). Further, the integration method was in 97% agreement with the multidisciplinary team in the resolution of a clinician's uncertain cases (35/36). TBR showed statistical power specific to supporting certainty of criterion E per the multidisciplinary team (Cohen's d, 1.53). Patients with relatively lower TBR were more likely to have other conditions that could affect criterion E certainty (10 significant results; P ≤ 0.05). Integration of this information with a clinician's ADHD evaluation could help improve diagnostic accuracy from 61% to 88%. Conclusions The EEG-based assessment aid may help improve accuracy of ADHD diagnosis by supporting greater criterion E certainty. PMID:25798338

Somatostatin receptor positron emission tomography/computed tomography using 68 Ga-labeled somatostatin analogs is the mainstay for the evaluation of receptor status in neuroendocrine tumors (NETs). This translates towards better therapy options, with increasing evidence of peptide receptor radionuclide therapy (PRRT) as the treatment of choice for advanced or progressive NETs. There are benefits in progression-free and overall survival as well as a significant improvement in clinical condition. In patients with progressive NETs, fractionated, personalized PRRT results in good therapeutic responses with no significant severe hematological and/or renal toxicity, thus improving quality of life.

To evaluate the clinical features of ankylosing spondylitis (AS) in Shantou area and improve the diagnostic level and therapeutic effect. Clinical and laboratory data, and the methods and effects of therapy were analyzed. Some patients were followed up. 94% of the cases had an insidious onset. Low back pain or discomfort, peripheral arthritis, positive "4" test and pressing tenderness over the sacroiliac joints and lumbar spine were the frequent symptoms and signs. The degree of sacroiliitis and involvement of hip and spine were related to the disease duration. However, hip joint involvement in juvenile onset AS did not relate to the disease duration. Some cases with disease duration as long as 16 years still remained at II of degree sacroiliitis. Clinical improvement was more obvious in the first two years of treatment. Although some patients came to a standstill condition after this period, yet the disease activity might still relapse with withdrawal of the treatment. The rate of adhering to the treatment for 1, 2, and over 5 years was 34.6%, 28.4%, and 10.3% respectively. The radiological changes frequently did not parallel with the clinical manifestations. Early diagnosis is of importance in improving the prognosis of AS and adherence to slow-acting anti-rheumatic drug therapy is beneficial in disease controlling. A follow up of more than 3 years is necessary to estimate the therapeutic efficacy, and the radiological change is the key indicator. AS is a heterogenic disease and the risk factors for prognosis should be further studied.

Transcranial direct current stimulation improves clinical symptoms in adolescents with attention deficit hyperactivity disorder.

Anodal transcranial direct current stimulation (tDCS) of the prefrontal cortex has repeatedly been shown to improve working memory. As patients with attention deficit hyperactivity disorder (ADHD) are characterized by both underactivation of the prefrontal cortex and deficits in working memory that correlate with clinical symptoms, it is hypothesized that the modulation of prefrontal activity with tDCS in patients with ADHD increases performance in working memory and reduces symptoms of ADHD. To test this hypothesis, fifteen adolescents with ADHD (12-16 years old, three girls and 12 boys) were treated according to the randomized, double-blinded, sham-controlled, crossover design with either 1 mA anodal tDCS over the left dorsolateral prefrontal cortex or with the sham protocol 5 days each with a 2 weeks pause between these conditions. Anodal tDCS caused a significant reduction in clinical symptoms of inattention and impulsivity in adolescents with ADHD compared to sham stimulation. The clinical effects were supported by a significant reduction in inattention and hyperactivity in a standardized working memory test (QbTest). The described effects were more pronounced 7 days after the end of stimulation, a fact which emphasizes the long-lasting clinical and neuropsychological changes after tDCS. This study provides the first evidence that tDCS may reduce symptoms of ADHD and improve neuropsychological functioning in adolescents and points on the potential of tDCS as a form of treatment for ADHD.

Experimental and Numerical Models of Complex Clinical Scenarios; Strategies to Improve Relevance and Reproducibility of Joint Replacement Research

This research review aims to focus attention on the effect of specific surgical and host factors on implant fixation, and the importance of accounting for them in experimental and numerical models. These factors affect (a) eventual clinical applicability and (b) reproducibility of findings across research groups. Proper function and longevity for orthopedic joint replacement implants relies on secure fixation to the surrounding bone. Technology and surgical technique has improved over the last 50 years, and robust ingrowth and decades of implant survival is now routinely achieved for healthy patients and first-time (primary) implantation. Second-time (revision) implantation presents with bone loss with interfacial bone gaps in areas vital for secure mechanical fixation. Patients with medical comorbidities such as infection, smoking, congestive heart failure, kidney disease, and diabetes have a diminished healing response, poorer implant fixation, and greater revision risk. It is these more difficult clinical scenarios that require research to evaluate more advanced treatment approaches. Such treatments can include osteogenic or antimicrobial implant coatings, allo- or autogenous cellular or tissue-based approaches, local and systemic drug delivery, surgical approaches. Regarding implant-related approaches, most experimental and numerical models do not generally impose conditions that represent mechanical instability at the implant interface, or recalcitrant healing. Many treatments will work well in forgiving settings, but fail in complex human settings with disease, bone loss, or previous surgery. Ethical considerations mandate that we justify and limit the number of animals tested, which restricts experimental permutations of treatments. Numerical models provide flexibility to evaluate multiple parameters and combinations, but generally need to employ simplifying assumptions. The objectives of this paper are to (a) to highlight the importance of mechanical, material, and surgical features to influence implant–bone healing, using a selection of results from two decades of coordinated experimental and numerical work and (b) discuss limitations of such models and the implications for research reproducibility. Focusing model conditions toward the clinical scenario to be studied, and limiting conclusions to the conditions of a particular model can increase clinical relevance and research reproducibility.

The socket-limb interface is vital for functionality and provides stability and mobility for the amputee. Volume fluctuation can lead to compromised fit and function. Current socket technology does not accommodate for volume fluctuation. An adjustable interface may improve function and comfort by filling this technology gap. The purpose of this study was to compare the effectiveness of the standard of care (SOC) ischial ramus containment to an adjustable transfemoral prosthetic interface socket in the accommodation of volume fluctuation. A prospective experimental case study using repeated measures of subjective and performance outcome measures between socket conditions was employed. In the baseline volume condition, the adjustable socket improved subjective and performance measures 19% to 37% over SOC, whereas the two-minute walk test demonstrated equivalence. In the volume loss condition, the adjustable socket improved all subjective and performance measures 22% to 93%. All aggregated data improved 16% to 50% compared with the SOC. In simulated volume gain, the SOC socket failed, while the subject was able to complete the protocol using the adjustable socket. In this case study, the SOC socket was inferior to the comparative adjustable transfemoral amputation interface in subjective and performance outcomes. There is a lack of clinical trials and evidence comparing socket functional outcomes related to volume fluctuation. PMID:28066526

Study Objectives: To investigate the efficacy of cognitive behavioral therapy for insomnia (CBTI) in adolescents. Design: A randomized controlled trial of CBTI in group therapy (GT), guided internet therapy (IT), and a waiting list (WL), with assessments at baseline, directly after treatment (post-test), and at 2 months follow-up. Setting: Diagnostic interviews were held at the laboratory of the Research Institute of Child Development and Education at the University of Amsterdam. Treatment for GT occurred at the mental health care center UvAMinds in Amsterdam, the Netherlands. Participants: One hundred sixteen adolescents (mean age = 15.6 y, SD = 1.6 y, 25% males) meeting DSM-IV criteria for insomnia, were randomized to IT, GT, or WL. Interventions: CBTI of 6 weekly sessions, consisted of psychoeducation, sleep hygiene, restriction of time in bed, stimulus control, cognitive therapy, and relaxation techniques. GT was conducted in groups of 6 to 8 adolescents, guided by 2 trained sleep therapists. IT was applied through an online guided self-help website with programmed instructions and written feedback from a trained sleep therapist. Measurements and Results: Sleep was measured with actigraphy and sleep logs for 7 consecutive days. Symptoms of insomnia and chronic sleep reduction were measured with questionnaires. Results showed that adolescents in both IT and GT, compared to WL, improved significantly on sleep efficiency, sleep onset latency, wake after sleep onset, and total sleep time at post-test, and improvements were maintained at follow-up. Most of these improvements were found in both objective and subjective measures. Furthermore, insomnia complaints and symptoms of chronic sleep reduction also decreased significantly in both treatment conditions compared to WL. Effect sizes for improvements ranged from medium to large. A greater proportion of participants from the treatment conditions showed high end-state functioning and clinically significant improvement after treatment and at follow-up compared to WL. Conclusions: This study is the first randomized controlled trial that provides evidence that cognitive behavioral therapy for insomnia is effective for the treatment of adolescents with insomnia, with medium to large effect sizes. There were small differences between internet and group therapy, but both treatments reached comparable endpoints. Clinical Trial Registration: This study was part of the clinical trial: Effectiveness of cognitive behavioral therapy for sleeplessness in adolescents; URL: http://www.isrctn.com/ISRCTN33922163; registration: ISRCTN33922163.

Chronic diseases disproportionately burden Aboriginal and Torres Strait Islander people in Australia, with cardiovascular (CV) diseases being the greatest contributor. To improve quality of life and life expectancy for people living with CV disease, secondary prevention strategies such as rehabilitation and self-management programs are critical. However, there is no published evidence examining the effect of chronic condition self-management (CCSM) group programs for Aboriginal and Torres Strait Islander people who have, or are at risk of, CV disease specifically. This study evaluates the Work It Out program for its effect on clinical outcome measures in urban Aboriginal and Torres Strait Islander participants with or at risk of CV disease. This study was underpinned by a conceptual framework based on Aboriginal and Torres Strait Islander community control. Participants had at least one diagnosed CV disease, or at least one CV disease risk factor. Short-term changes in clinical outcome measures over (approximately) 12 weeks were evaluated with a quasi-experimental, pre-post test design, using paired t-tests. Factors contributing to positive changes were tested using general linear models. The outcome measures included blood pressure (mmHg), weight (kg), body mass index (kg/m 2 ), waist and hip circumference (cm), waist to hip ratio (waist cm/hip cm) and six minute walk test (6MWT). Changes in several clinical outcome measures were detected, either within the entire group (n = 85) or within specific participant sub-groups. Participant's 6MWT distance improved by an average 0.053 km (95% CI: 0.01-0.07 km). The change in distance travelled was influenced by number of social and emotional wellbeing conditions participants presented with. The weight of participants classified with extreme obesity decreased on average by 1.6 kg (95% CI: 0.1-3.0 kg). Participants with high baseline systolic blood pressure demonstrated a mean decrease of 11 mmHg (95% CI: 3.2-18.8 mmHg). Change in blood pressure was influenced by the number of cardiovascular conditions participants experienced. Short-term improvements seen in some measures could indicate a trend for improvement in other indicators over the longer term. These results suggest the Work It Out program could be a useful model for cardiovascular rehabilitation and prevention for other urban Aboriginal and Torres Strait Islander populations.

To determine whether a practice-based intervention can improve care for falls, urinary incontinence, and cognitive impairment. Controlled trial. Two community medical groups. Community-dwelling patients (357 at intervention sites and 287 at control sites) aged 75 and older identified as having difficulty with falls, incontinence, or cognitive impairment. Intervention and control practices received condition case-finding, but only intervention practices received a multicomponent practice-change intervention. Percentage of quality indicators satisfied measured using a 13-month medical record abstraction. Before the intervention, the quality of care was the same in intervention and control groups. Screening tripled the number of patients identified as needing care for falls, incontinence, or cognitive impairment. During the intervention, overall care for the three conditions was better in the intervention than the control group (41%, 95% confidence interval (CI)=35-46% vs 25%, 95% CI=20-30%, P<.001). Intervention group patients received better care for falls (44% vs 23%, P<.001) and incontinence (37% vs 22%, P<.001) but not for cognitive impairment (44% vs 41%, P=.67) than control group patients. The intervention was more effective for conditions identified by screening than for conditions identified through usual care. A practice-based intervention integrated into usual clinical care can improve primary care for falls and urinary incontinence, although even with the intervention, less than half of the recommended care for these conditions was provided. More-intensive interventions, such as embedding intervention components into an electronic medical record, will be needed to adequately improve care for falls and incontinence.

Surgical reconstruction is commonly recommended for the treatment of tuberculous airway stenosis. The clinical conditions underlying tuberculous airway stenosis often involve both cicatricial stenosis and malacia. Surgical reconstruction alone may not improve the respiratory symptoms of patients with both types of airway stenosis. This study retrospectively reviewed patients who underwent surgical reconstruction for tuberculous airway stenosis to investigate the most appropriate treatment for this complicated condition. Twelve patients with tuberculous airway stenosis underwent surgical reconstruction at our institute from January 2003 to December 2013. The clinical courses of these patients were retrospectively reviewed. The 12 patients were 2 men and 10 women with a mean age of 36 years (range 17-61 years). The site of stenosis was the left main bronchus in six patients, trachea in four patients, and right main bronchus in two patients. The procedure performed was sleeve lobectomy in five patients, bronchial resection in four patients, and tracheal resection in three patients. Additional airway stenting was performed in two patients with concomitant malacia of the lower trachea. The performance status and Hugh-Jones classification improved postoperatively in all patients. The forced expiratory volume in 1 s as a percent of forced vital capacity and percent of forced expiratory volume in 1 s improved significantly. Surgical reconstruction is an acceptable treatment for tuberculous airway stenosis. Additional airway stenting may be needed in patients with symptomatic malacia.

Oral feedback from clinical educators is the traditional teaching method for improving clinical consultation skills in medical students. New approaches are needed to enhance this teaching model. Multisource feedback is a commonly used assessment method for learning among practising clinicians, but this assessment has not been explored rigorously in medical student education. This study seeks to evaluate if additional feedback on patient satisfaction improves medical student performance. The Patient Teaching Associate (PTA) Feedback Study is a single site randomized controlled, double-blinded trial with two parallel groups.An after-hours general practitioner clinic in Victoria, Australia, is adapted as a teaching clinic during the day. Medical students from two universities in their first clinical year participate in six simulated clinical consultations with ambulatory patient volunteers living with chronic illness. Eligible students will be randomized in equal proportions to receive patient satisfaction score feedback with the usual multisource feedback and the usual multisource feedback alone as control. Block randomization will be performed. We will assess patient satisfaction and consultation performance outcomes at baseline and after one semester and will compare any change in mean scores at the last session from that at baseline. We will model data using regression analysis to determine any differences between intervention and control groups. Full ethical approval has been obtained for the study. This trial will comply with CONSORT guidelines and we will disseminate data at conferences and in peer-reviewed journals. This is the first proposed trial to determine whether consumer feedback enhances the use of multisource feedback in medical student education, and to assess the value of multisource feedback in teaching and learning about the management of ambulatory patients living with chronic conditions.

Clinical time series prediction: Toward a hierarchical dynamical system framework.

PubMed

Liu, Zitao; Hauskrecht, Milos

2015-09-01

Developing machine learning and data mining algorithms for building temporal models of clinical time series is important for understanding of the patient condition, the dynamics of a disease, effect of various patient management interventions and clinical decision making. In this work, we propose and develop a novel hierarchical framework for modeling clinical time series data of varied length and with irregularly sampled observations. Our hierarchical dynamical system framework for modeling clinical time series combines advantages of the two temporal modeling approaches: the linear dynamical system and the Gaussian process. We model the irregularly sampled clinical time series by using multiple Gaussian process sequences in the lower level of our hierarchical framework and capture the transitions between Gaussian processes by utilizing the linear dynamical system. The experiments are conducted on the complete blood count (CBC) panel data of 1000 post-surgical cardiac patients during their hospitalization. Our framework is evaluated and compared to multiple baseline approaches in terms of the mean absolute prediction error and the absolute percentage error. We tested our framework by first learning the time series model from data for the patients in the training set, and then using it to predict future time series values for the patients in the test set. We show that our model outperforms multiple existing models in terms of its predictive accuracy. Our method achieved a 3.13% average prediction accuracy improvement on ten CBC lab time series when it was compared against the best performing baseline. A 5.25% average accuracy improvement was observed when only short-term predictions were considered. A new hierarchical dynamical system framework that lets us model irregularly sampled time series data is a promising new direction for modeling clinical time series and for improving their predictive performance.

A longitudinal study of clinical peer review's impact on quality and safety in U.S. hospitals.

PubMed

Edwards, Marc T

2013-01-01

Clinical peer review is the dominant method of event analysis in U.S. hospitals. It is pivotal to medical staff efforts to improve quality and safety, yet the quality assurance process model that has prevailed for the past 30 years evokes fear and is fundamentally antithetical to a culture of safety. Two prior national studies characterized a quality improvement model that corrects this dysfunction but failed to demonstrate progress toward its adoption despite a high rate of program change between 2007 and 2009. This study's online survey of 470 organizations participating in either of the prior studies further assessed relationships between clinical peer review program factors, including the degree of conformance to the quality improvement model (the QI model score), and subjectively measured program impact variables. Among the 300 hospitals (64%) that responded, the median QI model score was only 60 on a 100-point scale. Scores increased somewhat for the 2007 cohort (mean pair-wise difference of 5.9 [2-10]), but not for the 2009 cohort. The QI model is expanded as the result of the finding that self-reporting of adverse events, near misses, and hazardous conditions--an essential practice in high-reliability organizations--is no longer rare in hospitals. Self-reporting and the quality of case review are additional multivariate predictors of the perceived ongoing impact of clinical peer review on quality and safety, medical staff perceptions of the program, and medical staff engagement in quality and safety initiatives. Hospital leaders and trustees who seek to improve patient outcomes should facilitate the adoption of this best practice model for clinical peer review.

Stem Cell Therapy in Acute Myocardial Infarction: A Pot of Gold or Pandora's Box

2011-01-01

Stem cell therapy for conditions characterized by myocyte loss in myocardial infarction and heart failure is intuitively appealing. Stem cells from various sources, including heart itself in preclinical and animal studies, have shown the potential to improve the function of ventricular muscle after ischaemic injury. The clinical experience from worldwide studies have indicated the safety profile but with modest benefits. The predominant mechanisms of transplanted cells for improving cardiac function have pointed towards paracrine effects rather than transdifferentiation into cardiomyocytes. Thus, further investigations should be encouraged towards bench side and bedside to resolve various issues for ensuring the correct type and dosing of cells, time, and method of delivery and identify correct mechanism of functional improvement. An interdisciplinary effort at the scientific, clinical, and the government front will bring successful realization of this therapy for healing the heart and may convert what seems now a Pandora's Box into a Pot of Gold.

Chronic Fatigue Syndrome (CFS) is characterized by excessive fatigue after minimal physical or mental exertion, muscle and joint pain, poor concentration, dizziness, and sleep disturbances. We report here the effect of a yoga-based lifestyle intervention in a 30-year old male patient with a documented diagnosis of CFS with compromised quality of life (QoL) and altered personality. The patient initially attended a short-term yoga-based lifestyle intervention program that consisted of yoga-postures, breathing exercises (pranayama), meditation, group discussions, and individualized advice on stress management, diet and physical activity besides group support. Thereafter, patient attended 5 more such programs. There was a notable and consistent improvement in his clinical profile, positive aspects of personality and subjective well-being, and reduction in anxiety following this yoga-based lifestyle intervention. Overall, the results suggest that lifestyle intervention may improve clinical condition and personality in patients with CFS.

To investigate the clinical efficacy and safety of Liuwu Shengjing Decoction (LWD) in treating oligospermia and asthenospermia. One hundred and fourteen patients were randomized into two groups, the treated group administrated with self-formulated LWD, and the control group administrated with Wuzi Yanzong Pill (WYP). All were treated for 3 months. Patients' semen was analyzed before and after treatment, and the therapeutic efficacy was evaluated. The total effective rate was 94.8% in the treated group, with a partner pregnant rate of 8.6% (5/58), while in the control group, they were 85.7% and 5.4% (3/56) respectively. The efficacy in the treated group was better (P = 0.03). Patients' sperm count and viability of sperm were improved in both groups (P < 0.05 or P < 0.01), but the improvement in the treated group was superior (P < 0.05). LWD could effectively improve the condition of male infertility with oligospermia and asthenospermia.

Various retinal manifestations can occur following a febrile illness due to viral, bacterial or protozoal etiology. As there are limited data in the literature, we undertook this study to analyse the clinical presentation of post-fever retinitis due to various etiologies, as well as its course and management. This was a retrospective study of 14 consecutive cases who presented to the Vitreo Retina Department of our hospital over a 1-year period between January 2010 and December 2010. All patients underwent detailed ophthalmic examination and relevant investigations including fundus fluorescein angiography and optical coherence tomography (OCT). Basic and specific investigations were performed as necessary. All patients were given systemic steroids which were tapered based on clinical response. Twenty-one eyes of 14 patients (7 bilateral, 7 unilateral) were studied. Onset of ocular symptoms was approximately 3 weeks after fever. Four patients had specific etiology-one each of chikungunya, enteric fever, malaria and abdominal abscess with pneumococcal pneumonia. The presenting visual acuity of the affected eyes averaged 2/60. Six eyes had relative afferent pupillary defect. All patients had solitary or multiple patches of retinitis at the posterior pole and exudation at the macula. OCT through the lesions revealed inner retinal hyperreflectivity and thickening with after-shadowing. All patients showed improvement in vision with unilateral cases improving to an average of 6/12 and bilateral cases improving to an average of 6/24. Patients also showed resolution of retinitis, macular edema and serous detachment. Post-fever retinitis as a condition manifested approximately 3 weeks after onset of fever. Irrespective of the cause of the fever, clinical presentation of cases was similar with inner retinitis at the posterior pole and a favourable response to steroids, suggesting a possible immunological basis for this condition.

The Memory Aid study: protocol for a randomized controlled clinical trial evaluating the effect of computer-based working memory training in elderly patients with mild cognitive impairment (MCI)

PubMed Central

2014-01-01

Background Mild cognitive impairment (MCI) is a condition characterized by memory problems that are more severe than the normal cognitive changes due to aging, but less severe than dementia. Reduced working memory (WM) is regarded as one of the core symptoms of an MCI condition. Recent studies have indicated that WM can be improved through computer-based training. The objective of this study is to evaluate if WM training is effective in improving cognitive function in elderly patients with MCI, and if cognitive training induces structural changes in the white and gray matter of the brain, as assessed by structural MRI. Methods/Designs The proposed study is a blinded, randomized, controlled trail that will include 90 elderly patients diagnosed with MCI at a hospital-based memory clinic. The participants will be randomized to either a training program or a placebo version of the program. The intervention is computerized WM training performed for 45 minutes of 25 sessions over 5 weeks. The placebo version is identical in duration but is non-adaptive in the difficulty level of the tasks. Neuropsychological assessment and structural MRI will be performed before and 1 month after training, and at a 5-month folllow-up. Discussion If computer-based training results in positive changes to memory functions in patients with MCI this may represent a new, cost-effective treatment for MCI. Secondly, evaluation of any training-induced structural changes to gray or white matter will improve the current understanding of the mechanisms behind effective cognitive interventions in patients with MCI.

The SMILES trial was the first randomized controlled trial (RCT) explicitly designed to evaluate a dietary intervention, conducted by qualified dietitians, for reducing depressive symptomatology in adults with clinical depression. Here we detail the development of the prescribed diet (modified Mediterranean diet (ModiMedDiet)) for individuals with major depressive disorders (MDDs) that was designed specifically for the SMILES trial. We also present data demonstrating the extent to which this intervention achieved improvements in diet quality. The ModiMedDiet was designed using a combination of existing dietary guidelines and scientific evidence from the emerging field of nutritional psychiatric epidemiology. Sixty-seven community dwelling individuals (Melbourne, Australia) aged 18 years or over, with current poor quality diets, and MDDs were enrolled into the SMILES trial. A retention rate of 93.9 and 73.5% was observed for the dietary intervention and social support control group, respectively. The dietary intervention (ModiMedDiet) consisted of seven individual nutrition counselling sessions delivered by a qualified dietitian. The control condition comprised a social support protocol matched to the same visit schedule and length. This manuscript details the first prescriptive individualized dietary intervention delivered by dietitians for adults with major depression. Significant improvements in dietary quality were observed among individuals randomized to the ModiMedDiet group. These dietary improvements were also found to be associated with changes in depressive symptoms. The ModiMedDiet, a novel and individually tailored intervention designed specifically for adults with major depression, can be effectively implemented in clinical practice to manage this highly prevalent and debilitating condition.

Stakeholder-Driven Quality Improvement: A Compelling Force for Clinical Practice Guidelines.

PubMed

Rosenfeld, Richard M; Wyer, Peter C

2018-01-01

Clinical practice guideline development should be driven by rigorous methodology, but what is less clear is where quality improvement enters the process: should it be a priority-guiding force, or should it enter only after recommendations are formulated? We argue for a stakeholder-driven approach to guideline development, with an overriding goal of quality improvement based on stakeholder perceptions of needs, uncertainties, and knowledge gaps. In contrast, the widely used topic-driven approach, which often makes recommendations based only on randomized controlled trials, is driven by epidemiologic purity and evidence rigor, with quality improvement a downstream consideration. The advantages of a stakeholder-driven versus a topic-driven approach are highlighted by comparisons of guidelines for otitis media with effusion, thyroid nodules, sepsis, and acute bacterial rhinosinusitis. These comparisons show that stakeholder-driven guidelines are more likely to address the quality improvement needs and pressing concerns of clinicians and patients, including understudied populations and patients with multiple chronic conditions. Conversely, a topic-driven approach often addresses "typical" patients, based on research that may not reflect the needs of high-risk groups excluded from studies because of ethical issues or a desire for purity of research design.

2017-01-01

We improve data extrapolation for truncated computed tomography (CT) projections by using Helgason-Ludwig (HL) consistency conditions that mathematically describe the overlap of information between projections. First, we theoretically derive a 2D Fourier representation of the HL consistency conditions from their original formulation (projection moment theorem), for both parallel-beam and fan-beam imaging geometry. The derivation result indicates that there is a zero energy region forming a double-wedge shape in 2D Fourier domain. This observation is also referred to as the Fourier property of a sinogram in the previous literature. The major benefit of this representation is that the consistency conditions can be efficiently evaluated via 2D fast Fourier transform (FFT). Then, we suggest a method that extrapolates the truncated projections with data from a uniform ellipse of which the parameters are determined by optimizing these consistency conditions. The forward projection of the optimized ellipse can be used to complete the truncation data. The proposed algorithm is evaluated using simulated data and reprojections of clinical data. Results show that the root mean square error (RMSE) is reduced substantially, compared to a state-of-the-art extrapolation method.

2014-11-26

Our goal is to improve the safety and effectiveness of inpatient care. Rather than focus on improving process of care, we focus on the social structure within physician teams. We have developed the Physician Relationships, Improvising, and Sensemaking (PRISm) intervention to improve the way physician teams round, enabling them to better relate, make sense of their patients' conditions, and improvise in uncertain clinical situations. We are currently studying the impact of PRISm on adverse events and complications in hospitalized patients. This manuscript describes the PRISm intervention. PRISm is a structured communication tool consisting of three components: daily briefings before rounds; use of the Situation, Task, Intent, Concern, and Calibrate (STICC) framework during rounds as part of the discussion of individual patients; and debriefings after rounds. We are implementing the PRISm intervention on eight inpatient medical and surgical physician teams in the South Texas Veterans Health Care System. We are assessing PRISm impact on the way team members relate to each other, round, and discuss patients through pre- and post-implementation observations and surveys. We are also assessing PRISm impact on complications and adverse events. Finally, we are interviewing physicians regarding their experience using the intervention. Our results will allow us to begin to understand the potential impact of interventions designed to improve how providers relate to each other, improvise, and make sense of what is happening as a strategy for improving inpatient care. Our in-depth data collection will enable us to assess how relationships, improvising, and sensemaking influence patient outcomes, potentially through creating shared mental models or enhancing distributed cognition during clinical reasoning. Finally, our results will lay the groundwork for larger implementation studies to improve clinical outcomes through improving how providers, and providers, patients, and caregivers, relate.

Misophonia is a psychiatric disorder in which ordinary human sounds like smacking or chewing provoke intense anger and disgust. Despite the high burden of this condition, to date there is no evidence-based treatment available. In this study we evaluated the efficacy of cognitive behavioral therapy (CBT) and investigated whether clinical or demographic characteristics predicted treatment response. Ninety patients with misophonia received eight bi-weekly group CBT sessions. Treatment response was defined as a Clinical Global Impression - Improvement Scale (CGI-I) score at endpoint of 1 or 2 (very much or much improved) and a 30% or greater reduction on the Amsterdam Misophonia Scale (A-MISO-S), a measure of the severity of misophonia symptoms. Following treatment 48% (N=42) of the patients showed a significant reduction of misophonia symptoms. Severity of misophonia and the presence of disgust were positive predictors of treatment response. The A-MISO-S is not a validated scale. Furthermore, this was an open-label study with a waiting list control condition. This is the first treatment study for misophonia. Our results suggest that CBT is effective in half of the patients.

Thiamine (vitamin B1) deficiency is a common condition in alcohol abusers, which can lead to damage of both the peripheral and the central nervous systems. Here we describe the case of an alcoholic patient who presented with acute onset of ataxia, severe weakness of the four limbs, and hypoesthesia and dysesthesia of the distal portion of the upper and lower extremities. The clinical picture also included mental confusion and amnesia. A diagnosis of Wernicke-Korsakoff syndrome was made based on clinical symptoms and brain RMI findings. Electromyography and electroneurography revealed signs of subacute axonal sensory-motor polyneuropathy that were compatible with a rare acute presentation of beriberi. Patient immediately received parenteral thiamine administration, which resulted in rapid clinical amelioration of ataxia and confusion and also in a significant improvement of motor and sensory deficits. The association between Wernicke-Korsakoff syndrome and acute axonal polyneuropathy is a very rare condition that could make less recognizable the clinical picture of a thiamine deficiency. However, the diagnosis of thiamine deficiency should be suspected in every alcoholic patient presenting with acute onset symptoms of central and/or peripheral nervous system involvement. This because the immediate replacement treatment can be life-saving and reverse the clinical symptoms. Copyright © 2017 Elsevier B.V. All rights reserved.

2013-01-01

In this study we explored predictors and moderators of response to Internet-based cognitive behavioral therapy (CBT) and Internet-based problem-solving therapy (PST) for depressive symptoms. The sample consisted of 263 participants with moderate to severe depressive symptoms. Of those, 88 were randomized to CBT, 88 to PST and 87 to a waiting list control condition. Outcomes were improvement and clinically significant change in depressive symptoms after 8 weeks. Higher baseline depression and higher education predicted improvement, while higher education, less avoidance behavior and decreased rational problem-solving skills predicted clinically significant change across all groups. No variables were found that differentially predicted outcome between Internet-based CBT and Internet-based PST. More research is needed with sufficient power to investigate predictors and moderators of response to reveal for whom Internet-based therapy is best suited.

Chiropractic care offered at an on-site health center could reduce the economic and clinical burden of musculoskeletal conditions. A retrospective claims analysis and clinical evaluation were performed to assess the influence of on-site chiropractic services on health care utilization and outcomes. Patients treated off-site were significantly more likely to have physical therapy (P < 0.0001) and outpatient visits (P < 0.0001). In addition, the average total number of health care visits, radiology procedures, and musculoskeletal medication use per patient with each event were significantly higher for the off-site group (all P < 0.0001). Last, headache, neck pain, and low back pain-functional status improved significantly (all P < 0.0001). These results suggest that chiropractic services offered at on-site health centers may promote lower utilization of certain health care services, while improving musculoskeletal function.

Using Virtual Reality to Improve Walking Post-Stroke: Translation to Individuals with Diabetes

2011-01-01

Use of virtual reality (VR) technology to improve walking for people post-stroke has been studied for its clinical application since 2004. The hardware and software used to create these systems has varied but has predominantly been constituted by projected environments with users walking on treadmills. Transfer of training from the virtual environment to real-world walking has modest but positive research support. Translation of the research findings to clinical practice has been hampered by commercial availability and costs of the VR systems. Suggestions for how the work for individuals post-stroke might be applied and adapted for individuals with diabetes and other impaired ambulatory conditions include involvement of the target user groups (both practitioners and clients) early in the design and integration of activity and education into the systems.

Self-management programs aim to improve patients' skills to manage their chronic condition in everyday life. Improvement in self-management is assumed to bring about improvements in more distal outcomes, such as quality of life. This study aimed to test the hypothesis that changes in self-reported self-management skills observed after participation in self-management programs predict changes in both quality of life and depressive symptoms three months later. Using latent change modeling, the relationship between changes in latent variables over three time points (start and end of rehabilitation, after three months) was analysed. The sample comprised 580 patients with different chronic conditions treated in inpatient rehabilitation clinics. The influence of additional predictor variables (age, sex, perceived social support) and type of disorder as a moderator variable was also tested. Changes in self-reported self-management skills after rehabilitation predicted changes in both quality of life and depressive symptoms at the end of rehabilitation and the 3 months follow-up. These relationships remained significant after the inclusion of other predictor variables and were similar across disorders. The findings provide support for the hypothesis that improvements in proximal outcomes of self-management programs may foster improvements in distal outcomes. Further studies should investigate treatment mechanisms. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Otopalatodigital spectrum disorders (OPDSD) include OPD syndromes types 1 and type 2 (OPD1, OPD2), Melnick-Needles syndrome (MNS), and frontometaphyseal dysplasia (FMD). These conditions are clinically characterized by variable skeletal dysplasia associated in males, with extra-skeletal features including brain malformations, cleft palate, cardiac anomalies, omphalocele and obstructive uropathy. Mutations in the FLNA gene have been reported in most FMD and OPD2 cases and in all instances of typical OPD1 and MNS. Here, we report a series of 10 fetuses and a neonatally deceased newborn displaying a multiple congenital anomalies syndrome suggestive of OPDSD and in whom we performed FLNA analysis. We found a global mutation rate of 44%. This series allows expanding the clinical and FLNA mutational spectrum in OPDSD. However, we emphasize difficulties to correctly discriminate OPDSD based on clinical criteria in fetuses due to the major overlap between these conditions. Molecular analyses may help pathologists to refine clinical diagnosis according to the type and the location of FLNA mutations. Discriminating the type of OPDSD is of importance in order to improve the genetic counseling to provide to families. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Pattern Recognition of the Multiple Sclerosis Syndrome

Stewart, Renee; Healey, Kathleen M.

2017-01-01

During recent decades, the autoimmune disease neuromyelitis optica spectrum disorder (NMOSD), once broadly classified under the umbrella of multiple sclerosis (MS), has been extended to include autoimmune inflammatory conditions of the central nervous system (CNS), which are now diagnosable with serum serological tests. These antibody-mediated inflammatory diseases of the CNS share a clinical presentation to MS. A number of practical learning points emerge in this review, which is geared toward the pattern recognition of optic neuritis, transverse myelitis, brainstem/cerebellar and hemispheric tumefactive demyelinating lesion (TDL)-associated MS, aquaporin-4-antibody and myelin oligodendrocyte glycoprotein (MOG)-antibody NMOSD, overlap syndrome, and some yet-to-be-defined/classified demyelinating disease, all unspecifically labeled under MS syndrome. The goal of this review is to increase clinicians’ awareness of the clinical nuances of the autoimmune conditions for MS and NMSOD, and to highlight highly suggestive patterns of clinical, paraclinical or imaging presentations in order to improve differentiation. With overlay in clinical manifestations between MS and NMOSD, magnetic resonance imaging (MRI) of the brain, orbits and spinal cord, serology, and most importantly, high index of suspicion based on pattern recognition, will help lead to the final diagnosis.

The objective of this review is to investigate the detailed existing scientific information about the clinical efficacy of acupuncture on rheumatoid arthritis (RA) conditions and to reveal the proposed mechanisms. We searched the PubMed, EMBASE, Cochrane, AMED (Allied and Complementary Medicine), NCCAM (The National Center for Complementary and Alternative Medicine), and CNKI (China National Knowledge Infrastructure) databases to identify relevant monographs and related references from 1974 to 2018. Chinese journals and theses/dissertations were hand searched. 43 studies were recruited. Each research was analyzed for study design, subject characteristics, intervention, selected acupoints, assessment parameters, proposed mechanisms, and results/conclusions. In our review, we concluded that acupuncture alone or combined with other treatment modalities is beneficial to the clinical conditions of RA without adverse effects reported and can improve function and quality of life and is worth trying. Several important possible mechanisms were summarized including anti-inflammatory effect, antioxidative effect, and regulation of immune system function. However, there is still inconsistency regarding the clinical efficacy and lack of well-designed human/animal double-blinded RCTs. Future discussion for further agreement on taking traditional Chinese medicine (TCM) theory into consideration as much as possible is a top priority.

A generalized decision tree or clinical algorithm for treatment of high-risk elective surgical patients was developed from a physiologic model based on empirical data. First, a large data bank was used to do the following: (1) describe temporal hemodynamic and oxygen transport patterns that interrelate cardiac, pulmonary, and tissue perfusion functions in survivors and nonsurvivors; (2) define optimal therapeutic goals based on the supranormal oxygen transport values of high-risk postoperative survivors; (3) compare the relative effectiveness of alternative therapies in a wide variety of clinical and physiologic conditions; and (4) to develop criteria for titration of therapy to the endpoints of the supranormal optimal goals using cardiac index (CI), oxygen delivery (DO2), and oxygen consumption (VO2) as proxy outcome measures. Second, a general purpose algorithm was generated from these data and tested in preoperatively randomized clinical trials of high-risk surgical patients. Improved outcome was demonstrated with this generalized algorithm. The concept that the supranormal values represent compensations that have survival value has been corroborated by several other groups. We now propose a unique approach to refine the generalized algorithm to develop customized algorithms and individualized decision analysis for each patient's unique problems. The present article describes a preliminary evaluation of the feasibility of artificial intelligence techniques to accomplish individualized algorithms that may further improve patient care and outcome.

Background Improving asthma patients’ quality of life is an important clinical outcome. This study evaluated the efficacy of mindfulness-based stress reduction (MBSR) in improving quality of life and lung function in patients with asthma. Methods A randomized controlled trial compared an 8 week MBSR group-based program (n = 42) to an educational control program (n = 41) in adults with mild, moderate or severe persistent asthma recruited at a university hospital outpatient primary care and pulmonary care clinic. Primary outcomes were quality of life assessed by the Asthma Quality of Life Questionnaire (AQOL), and lung function assessed by change from baseline in two-week average morning peak expiratory flow (PEF). Secondary outcomes were asthma control assessed by 2007 NIH/NHLBI guidelines, and stress assessed by Perceived Stress Scale. Follow-up assessments were conducted at 10 weeks, 6 and 12 months. Results At 12 months MBSR resulted in clinically significant improvements in quality of life (intervention effect 0.55 (95% CI 0.21, 0.89, p=0.001)) and perceived stress (intervention effect −4.5 (95% CI −7.1, −1.9; p= 0.001)). No significant effect was found on lung function (morning PEF, PEF variability, and FEV1). At 12 months the percentage of patients in MBSR with well-controlled asthma showed a non-statistically significant increase (7.3% at baseline to 19.4%) compared to the control condition (7.5% and 7.9%, respectively) (p=0.30). Conclusions MBSR produced lasting clinically significant improvements in asthma-related quality of life and stress in patients with persistent asthma, even in the absence of improvements in lung function.

Recent advances in molecular genetics have translated into the increasing utilisation of genetic testing in the routine clinical practice of neurologists. There has been a steady, incremental increase in understanding the genetic variation associated with epilepsies. Genetic testing in the epilepsies is not yet widely practiced, but the advent of new screening technologies promises to exponentially expand both knowledge and clinical utility. To maximise the value of this new genetic insight we need to rapidly extrapolate genetic findings to inform patients of their diagnosis, prognosis, recurrence risk and the clinical management options available for their specific genetic condition. Comprehensive, highly specific and sensitive genetic test results improve the management of patients by neurologists and clinical geneticists. Here we discuss the latest developments in clinical genetic testing for epilepsy and describe new molecular genetics platforms that will transform both genetic screening and novel gene discovery.

Healthcare students as innovative partners in the development of future healthcare services: An action research approach.

Norbye, Bente

2016-11-01

Health care systems in Norway and the western world have experienced extensive changes due to patients living longer with complex conditions that require coordinated care. A Norwegian healthcare reform has led to significant restructuring in service delivery as a devolution of services to municipalities. Partners from three rural healthcare services, students from four professional programmes, and one lecturer from each of the professional programmes used a collaborative approach to obtain new knowledge through interprofessional practice. Using an action research design, the research group facilitated democratic processes through dialogues with healthcare services and students. The design is visualised as a cyclical process in which each cycle contributes to improvements, innovations, and increased understanding. A total of 32 students and 3 supervisors were interviewed before and after the clinical practice experiences. Fieldwork was conducted during three clinical periods. Interprofessional student groups formed small healthcare teams and assessed patients with chronic and long-term conditions. Students prepared and negotiated patient follow-up. The teams' responsibilities led to reflective practices that enhanced their professional knowledge. The teams achieved a new understanding of patient situations, which influenced "second opinions" for patients with complex conditions and led to innovative practices. The change in perception of patient needs led to a changed professional approach. The students' perceptions changed as they learned from and about each other and in collaboration with the health service; this led to more coordinated care of patients with complex conditions. Interprofessional learning in community settings provided a platform to improve both healthcare education and rural healthcare services. This research contributes to knowledge of how students' placement in interprofessional teams can enhance students learning from, with and about each other. The student teams promoted new ways of approaching and delivering complex patient treatment and care in community healthcare service. Collaborative partnerships in interprofessional learning have potential in the wider international arena as a means for practice improvement. Copyright © 2016 Elsevier Ltd. All rights reserved.

Clinical trials are essential to cancer care, and data about the current state of research in oncology are needed to develop benchmarks and set the stage for improvement. To perform a comprehensive analysis of the national oncology clinical research portfolio. All interventional clinical studies registered on ClinicalTrials.gov between October 2007 and September 2010 were identified using Medical Subject Heading terms and submitted conditions. They were reviewed to validate classification, subcategorized by cancer type, and stratified by design characteristics to facilitate comparison across cancer types and with other specialties. Of 40 970 interventional studies registered between October 2007 and September 2010, a total of 8942 (21.8%) focused on oncology. Compared with other specialties, oncology trials were more likely to be single arm (62.3% vs 23.8%; P < .001), open label (87.8% vs 47.3%; P < .001), and nonrandomized (63.9% vs 22.7%; P < .001). There was moderate but significant correlation between number of trials conducted by cancer type and associated incidence and mortality (Spearman rank correlation coefficient, 0.56 [P = .04] and 0.77 [P = .001], respectively). More than one-third of all oncology trials were conducted solely outside North America. There are significant variations between clinical trials in oncology and other diseases, as well as among trials within oncology. The differences must be better understood to improve both the impact of cancer research on clinical practice and the use of constrained resources.

Background To examine (1) changes in parent (global psychological distress, trait anxiety) and family (dysfunction, burden) functioning following 12 weeks of child-focused anxiety treatment, and (2) whether changes in these parent and family factors were associated with child's treatment condition and response. Methods Participants were 488 youth ages 7–17 years (50% female; mean age 10.7 years) who met DSM-IV-TR criteria for social phobia, separation anxiety, and/or generalized anxiety disorder, and their parents. Youth were randomly assigned to 12 weeks of “Coping Cat” individual cognitive-behavioral therapy (CBT), medication management with sertraline (SRT), their combination (COMB), or medication management with pill placebo (PBO) within the multisite Child/Adolescent Anxiety Multimodal Study (CAMS). At pre- and posttreatment, parents completed measures of trait anxiety, psychological distress, family functioning, and burden of child illness; children completed a measure of family functioning. Blinded independent evaluators rated child's response to treatment using the Clinical Global Impression-Improvement Scale at posttreatment. Results Analyses of covariance revealed that parental psychological distress and trait anxiety, and parent-reported family dysfunction improved only for parents of children who were rated as treatment responders, and these changes were unrelated to treatment condition. Family burden and child-reported family dysfunction improved significantly from pre- to posttreatment regardless of treatment condition or response. Conclusions Findings suggest that child-focused anxiety treatments, regardless of intervention condition, can result in improvements in nontargeted parent symptoms and family functioning particularly when children respond successfully to the treatment.

Background Approximately 20% of oocytes are classified as immature and discarded following intracytoplasmic sperm injection (ICSI) procedures. These oocytes are obtained from gonadotropin-stimulated patients, and are routinely removed from the cumulus cells which normally would mature the oocytes. Given the ready access to these human oocytes, they represent a potential resource for both clinical and basic science application. However culture conditions for the maturation of cumulus-free oocytes have not been optimized. We aimed to improve maturation conditions for cumulus-free oocytes via culture with ovarian paracrine/autocrine factors identified by single cell analysis. Methodology/Principal Finding Immature human oocytes were matured in vitro via supplementation with ovarian paracrine/autocrine factors that were selected based on expression of ligands in the cumulus cells and their corresponding receptors in oocytes. Matured oocytes were artificially activated to assess developmental competence. Gene expression profiles of parthenotes were compared to IVF/ICSI embryos at morula and blastocyst stages. Following incubation in medium supplemented with ovarian factors (BDNF, IGF-I, estradiol, GDNF, FGF2 and leptin), a greater percentage of oocytes demonstrated nuclear maturation and subsequently, underwent parthenogenesis relative to control. Similarly, cytoplasmic maturation was also improved as indicated by development to blastocyst stage. Parthenogenic blastocysts exhibited mRNA expression profiles similar to those of blastocysts obtained after IVF/ICSI with the exception for MKLP2 and PEG1. Conclusions/Significance Human cumulus-free oocytes from hormone-stimulated cycles are capable of developing to blastocysts when cultured with ovarian factor supplementation. Our improved IVM culture conditions may be used for obtaining mature oocytes for clinical purposes and/or for derivation of embryonic stem cells following parthenogenesis or nuclear transfer.

Objective Chronic insomnia is highly prevalent among military personnel returning from Iraq and Afghanistan. We evaluated the effects of a military version of a brief behavioral treatment of insomnia (BBTI-MV) compared to an information only control (IC) condition in combat-exposed Veterans of Operations Enduring/Iraqi Freedom or Operation New Dawn (OEF/OIF/OND) on insomnia, sleep quality, and daytime symptoms of anxiety and depression. Method Forty OEF/OIF/OND Veterans (Mean age = 38.4 years old, s.d. = 11.69; 85% men; 77.5% white) were randomized to one of two conditions. BBTI-MV consisted of two in-person sessions and two telephone contacts delivered over four weeks, and included personalized recommendations to reduce insomnia. The IC condition also consisted of 2 in-person sessions two telephone contacts delivered over four weeks, and Veterans were encouraged to read written information about sleep-promoting behaviors. The Insomnia Severity Index, Pittsburgh Sleep Quality Index, PTSD Checklist, and Beck Depression and Anxiety Inventories were completed at baseline, post-treatment, and at the six-month follow-up. Results Both interventions were associated with clinically significant improvements in insomnia, although the magnitude of improvements in sleep and rates of treatment response and remission were greater for BBTI-MV compared to IC from pre- to post-treatment. Conclusion Both BBTI-MV and the provision of information were associated with clinically significant improvements in insomnia among Veterans. Despite the preliminary nature of the findings and limitations inherent to small controlled trials, the findings suggest that both approaches may provide viable options in a stepped-care approach to the treatment of insomnia in retuning combat-exposed Veterans. Larger, confirmatory effectiveness trials are required. PMID:25194223

Venous thromboembolism (VTE) is a common cause of preventable harm in hospitalized patients. While numerous successful interventions have been implemented to improve prescription of VTE prophylaxis, a substantial proportion of doses of prescribed preventive medications are not administered to hospitalized patients. The purpose of this trial was to evaluate the effectiveness of nurse education on medication administration practice. This was a double-blinded, cluster randomized trial in 21 medical or surgical floors of 933 nurses at The Johns Hopkins Hospital, an academic medical center, from April 1, 2014 -March 31, 2015. Nurses were cluster-randomized by hospital floor to receive either a linear static education (Static) module with voiceover or an interactive learner-centric dynamic scenario-based education (Dynamic) module. The primary and secondary outcomes were non-administration of prescribed VTE prophylaxis medication and nurse-reported satisfaction with education modules, respectively. Overall, non-administration improved significantly following education (12.4% vs. 11.1%, conditional OR: 0.87, 95% CI: 0.80-0.95, p = 0.002) achieving our primary objective. The reduction in non-administration was greater for those randomized to the Dynamic arm (10.8% vs. 9.2%, conditional OR: 0.83, 95% CI: 0.72-0.95) versus the Static arm (14.5% vs. 13.5%, conditional OR: 0.92, 95% CI: 0.81-1.03), although the difference between arms was not statistically significant (p = 0.26). Satisfaction scores were significantly higher (p<0.05) for all survey items for nurses in the Dynamic arm. Education for nurses significantly improves medication administration practice. Dynamic learner-centered education is more effective at engaging nurses. These findings suggest that education should be tailored to the learner. ClinicalTrials.gov NCT02301793.

The detection of adverse drug events (ADEs) is an important aspect of improving patient safety. The iMedication system employs predefined triggers associated with significant events in a patient's clinical data to automatically detect possible ADEs. We defined four clinically relevant conditions: hyperkalemia, hyponatremia, renal failure, and over-anticoagulation. These are some of the most relevant ADEs in internal medical and geriatric wards. For each patient, ADE risk scores for all four situations are calculated, compared against a threshold, and judged to be monitored, or reported. A ward-based cockpit view summarizes the results.

Low back pain (LBP) is a prevalent and costly condition. Awareness of valid and reliable patient history taking, physical examination and clinical testing is important for diagnostic accuracy. Stratified care which targets treatment to patient subgroups based on key characteristics is reliant upon accurate diagnostics. Models of stratified care that can potentially improve treatment effects include prognostic risk profiling for persistent LBP, likely response to specific treatment based on clinical prediction models or suspected underlying causal mechanisms. The focus of this editorial is to highlight current research status and future directions for LBP diagnostics and stratified care.

Although sleep has been shown to enhance motor skill learning, it remains unclear whether sleep enhances learning of a functional motor task in middle-aged and older individuals. The purpose of this study was to examine whether sleep enhances motor learning of a functional motor task in middle-aged and older adults. Twenty middle-aged and 20 older individuals were randomly assigned to either the sleep condition or the no-sleep condition. Participants in the sleep condition practiced a novel walking task in the evening, and returned the following morning for retesting. Participants in the no-sleep condition practiced the walking task in the morning and returned the same day in the evening for a retest. Outcome measures included time around the walking path and spatiotemporal gait parameters. Only the middle-aged and older adults in the sleep condition demonstrated significant off-line improvement in performance, measured as a decline in time to walk around the novel path and improvement in spatiotemporal gait parameters. The middle-aged and older adults in the no-sleep condition failed to demonstrate off-line improvements in performance of this functional task. This is the first study to provide evidence that sleep facilitates learning a clinically relevant functional motor task in middle-aged and older adults. Because many neurologic conditions occur in the middle-aged and older adults and sleep issues are very prevalent in many neurologic conditions, it is imperative that physical therapists consider sleep as a factor that may impact motor learning and recovery in these individuals.

Immunomodulatory properties of human umbilical cord-derived mesenchymal stromal cells (UCMSCs) can be differentially modulated by toll-like receptors (TLR) agonists. Here, the therapeutic efficacy of short TLR3 and TLR4 pre-conditioning of UCMSCs was evaluated in a dextran sulfate sodium (DSS)-induced colitis in mice. The novelty of this study is that although modulation of human MSCs activity by TLRs is not a new concept, this is the first time that short TLR pre-conditioning has been carried out in a murine inflammatory model of acute colitis. C57BL/6 mice were exposed to 2.5% dextran sulfate sodium (DSS) in drinking water ad libitum for 7 days. At days 1 and 3, mice were injected intraperitoneally with 1 × 10(6) UCMSCs untreated or TLR3 and TLR4 pre-conditioned UCMSCs. UCMSCs were pre-conditioned with poly(I:C) for TLR3 and LPS for TLR4 for 1 h at 37°C and 5% CO2. We evaluated clinical signs of disease and body weights daily. At the end of the experiment, colon length and histological changes were assessed. poly(I:C) pre-conditioned UCMSCs significantly ameliorated the clinical and histopathological severity of DSS-induced colitis compared with UCMSCs or LPS pre-conditioned UCMSCs. In contrast, infusion of LPS pre-conditioned UCMSCs significantly increased clinical signs of disease, colon shortening and histological disease index in DSS-induced colitis. These results show that short in vitro TLR3 pre-conditioning with poly(I:C) enhances the therapeutic efficacy of UCMSCs, which is a major breakthrough for developing improved treatments to patients with inflammatory bowel disease.

The wonderland of neuronal nicotinic acetylcholine receptors.

PubMed

Bertrand, Daniel; Terry, A V

2018-05-01

Nearly 30 years of experimental evidence supports the argument that ligands of nicotinic acetylcholine receptors (nAChRs) have potential as therapeutic agents. However, as in the famous Lewis Carroll novel "Alice in Wonderland", there have been many unexpected adventures along the pathway of development, and few nAChR ligands have been approved for any clinical condition to date with the exception of nicotine dependence. The recent failures of nAChR ligands in AD and schizophrenia clinical trials have reduced enthusiasm for this therapeutic strategy and many pharmaceutical companies have now abandoned this field of research. As with other clinical failures, multiple questions arise as to the basis for the failure. More generic questions focus on a potential translational gap between the animal models used and the human clinical condition they are meant to simulate, or the clinical trial mindset that large Ns have to be achieved for statistical power (often requiring multiple trial sites) as opposed to smaller patient cohorts at limited sites where conditions can be better controlled and replicated. More specific to the nAChR field are questions about subtype selectivity, dose selection, whether an agonist, antagonist, or allosteric modulator strategy is best, etc. The purpose of this review is to discuss each of these questions, but also to provide a brief overview of the remarkable progress that has been made over the last three decades in our understanding of this unique ligand-gated ion channel and how this new knowledge may help us improve drug development successes in the future.

Four-corner fusion is a rational surgical option for the management of degenerative conditions of the wrist. Most related studies have compared four-corner fusion with scaphoid excision or proximal row carpectomy, with a variety of reported results. To enhance the literature, we performed this study to evaluate a series of patients with degenerative conditions of the wrist treated with four-corner fusion using 3 surgical techniques and to discuss the clinical and radiographic outcome of the patients. We retrospectively studied 31 patients (24 men, 7 women; mean age, 43 years; 9 heavy manual laborers) who underwent four-corner fusion of their wrists for degenerative conditions from 2005 to 2015. Internal fixation was done using multiple Kirschner wires (14 patients), headless compressive screws (8 patients), or a circular plate (9 patients). Mean follow-up was 4 years (1-11 years). We evaluated the clinical outcome with the Patient-Rated Wrist Evaluation (PRWE) score and fusion with radiographs. All patients experienced improvement of their pain, function, range of motion and grip strength (p < 0.05). Twenty-three patients (74 %) reported no pain, and eight patients reported mild, occasional pain. Twenty-one patients (68 %) were able to do usual and specific activities. Mean wrist motion improved to 70 % and mean grip strength improved to 85 % of opposite wrist. Two heavy manual labor patients requested a job modification because of wrist impairment. Radiographs of the wrist showed fusion of all fused joints in 28 (90.3 %) patients and partial fusion in three patients (9.7 %). No patient with partial fusion required a reoperation for symptomatic nonunion until the period of this study. Three patients experienced complications (10 %). Two patients treated with a circular plate experienced complex regional pain syndrome and painful implant impingement; another patient treated with Kirschner wires and headless compression screws experienced radiolunate arthritis from impingement of the lunate screw to the radius. Four-corner fusion is a reliable limited wrist fusion technique that provides pain relief, grip strength and satisfactory range of motion in patients with degenerative conditions of the wrist. Partial union is more common with Kirschner wire fixation and complications are more common with circular plate fixation.
