Bronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis) that has been associated with contact with domestic Caprinae. The disease is polymicrobial but is initiated by Mycoplasma ovipneumoniae, which is commonly carried by both domestic sheep (O. aries) and goats (Capra aegagrus hircus). However, while previous bighorn sheep comingling studies with domestic sheep have resulted in nearly 100% pneumonia mortality, only sporadic occurrence of fatal pneumonia was reported from previous comingling studies with domestic goats. Here, we evaluated the ability of domestic goats of defined M. ovipneumoniae carriage status to induce pneumonia in comingled bighorn sheep. In experiment 1, three bighorn sheep naïve to M. ovipneumoniae developed non-fatal respiratory disease (coughing, nasal discharge) following comingling with three naturally M. ovipneumoniae-colonized domestic goats. Gross and histological lesions of pneumonia, limited to small areas on the ventral and lateral edges of the anterior and middle lung lobes, were observed at necropsies conducted at the end of the experiment. A control group of three bighorn sheep from the same source housed in isolation during experiment 1 remained free of observed respiratory disease. In experiment 2, three bighorn sheep remained free of observed respiratory disease while comingled with three M. ovipneumoniae-free domestic goats. In experiment 3, introduction of a domestic goat-origin strain of M. ovipneumoniae to the same comingled goats and bighorn sheep used in experiment 2 resulted in clinical signs of respiratory disease (coughing, nasal discharge) in both host species. At the end of experiment 3, gross and histological evidence of pneumonia similar to that observed in experiment 1 bighorn sheep was observed in both affected bighorn sheep and domestic goats. M. ovipneumoniae strains carried by domestic goats were transmitted to comingled bighorn sheep, triggering development of pneumonia. However, the severity of the disease was markedly milder than that seen in similar experiments with domestic sheep strains of the bacterium.

Considerable progress has been achieved in recent years in treating children affected by bone diseases. Advances in the understanding of the molecular pathophysiology of genetic bone diseases have led to the development of enzyme replacement therapies for various lysosomal storage diseases, following the breakthrough initiated in treating Gaucher disease. Clinical studies are underway with tailored molecules correcting bone fragility and alleviating chronic bone pain and other manifestations of hypophosphatasia, or promoting growth of long bones in achondroplasia patients. We further report our very encouraging experience with intravenous bisphosphonate treatment in children suffering from secondary osteopenia and the high prevalence of calcium and vitamin D deficits in these severely disabled children.

Alzheimer’s Disease and Its Treatment With a Novel Transdermal Patch Therapy: Survey of Caregiver Experiences

PubMed Central

Pepp, Mike

2012-01-01

Objective: To investigate experiences and perceptions of caregivers of patients with Alzheimer’s disease using transdermal patch therapy. Method: Assessment methods for the pilot study comprised an interview between the caregiver and a moderator, an interview between 1 moderator and 2 caregivers, or a video diary. The subsequent quantitative study involved a 45-minute telephone questionnaire. For both studies, participants were required to be the principal caregiver of a patient with Alzheimer’s disease who had been receiving transdermal patch therapy for at least 3 months. Their responses were grouped into the following 6 themes: interpersonal relationships, impact on caregivers, from symptoms to treatment, help and support for caregivers, daily routine, and caregiver experience with the patch. Results: Overall, 206 caregivers were enrolled from France, Germany, Greece, Spain, and the United States between July 2009 and January 2011 (pilot study: N = 56; quantitative study: N = 150). The studies revealed that caregivers of patients with Alzheimer’s disease experienced emotional and practical impacts, and many felt that they had not received sufficient information from health care providers about Alzheimer’s disease, treatment options, or available support. In the quantitative study, 47% of caregivers who had been caring for the patient prior to diagnosis (61% of total respondents) felt that there had been a delay in seeking medical advice, frequently due to slow onset of symptoms of Alzheimer’s disease. In both studies, patch therapy was considered more convenient and easier to administer than oral treatments. The practical and efficacy advantages of the patch often translated into emotional benefits. Conclusions: With recent data highlighting the importance of early initiation of symptomatic Alzheimer’s disease therapy and the importance of reaching an optimal therapeutic dose, reasons for delay in treatment initiation need to be explored. Information that patients and caregivers receive at the time of diagnosis may aid therapeutic decisions. PMID:23251856

[Treatment of pulmonary arterial hypertension].

2015-06-22

Treatment of pulmonary arterial hypertension has achieved significant progress over the past 20 years. Currently, 3 groups of drugs have proven useful for the treatment of this disease: endothelin receptor antagonist, phosphodiesterase inhibitors and prostacyclin and its analogues. It is recommended to initiate treatment with one of these drugs, the choice depending on the initial severity of patient disease and the preferences of the treating physician. When the patient does not have a satisfactory response, new drugs acting at a different pathway are most commonly added. At this time, considering referral for lung transplantation could be an alternative. Most experts recommend grouping maximum experience in what is known as expert centers. Treatment has led to better survival in these patients, but there is still a long way to cure this life-threatening disease. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Building chronic disease management capacity in General Practice: The South Australian GP Plus Practice Nurse Initiative.

2015-01-01

This paper draws on the implementation experience of the South Australian GP Plus Practice Nurse Initiative in order to establish what is needed to support the development of the chronic disease management role of practice nurses. The Initiative was delivered between 2007 and 2010 to recruit, train and place 157 nurses across 147 General Practices in Adelaide. The purpose was to improve chronic disease management in General Practice, by equipping nurses to work as practice nurses who would coordinate care and establish chronic disease management systems. Secondary analysis of qualitative data contained in the Initiative evaluation report, specifically drawing on quarterly project records and four focus groups conducted with practice nurses, practice nurse coordinators and practice nurse mentors. As evidenced by the need to increase the amount of support provided during the implementation of the Initiative, nurses new to General Practice faced challenges in their new role. Nurses described a big learning curve as they dealt with role transition to a new work environment and learning a range of new skills while developing chronic disease management systems. Informants valued the skills development and support offered by the Initiative, however the ongoing difficulties in implementing the role suggested that change is also needed at the level of the Practice. While just over a half of the placement positions were retained, practice nurses expressed concern with having to negotiate the conditions of their employment. In order to advance the role of practice nurses as managers of chronic disease support is needed at two levels. At one level support is needed to assist practice nurses to build their own skills. At the level of the Practice, and in the wider health workforce system, support is also needed to ensure that Practices are organisationally ready to include the practice nurse within the practice team.

Purpose Premature closure has been identified as the single most common cause of diagnostic error. The authors conducted a factorial experiment to explore which variables exert an unconfounded influence on physicians’ diagnostic flexibility (changing their minds about the most likely diagnosis during a clinical case presentation). Methods In 2007–2008, 256 practicing physicians viewed a clinically authentic vignette simulating a patient presenting with possible coronary heart disease (CHD), provided their initial impression midway through the case, answered questions about the case, indicated how they would continue their clinical investigation, and made a final diagnosis. The authors used general linear models to determine which patient factors (age, gender, socioeconomic status, race), physician factors (gender, age/experience), and process variables were related to the likelihood of physicians’ changing their minds about the most likely diagnosis. Results Physicians who had less experience, those who named a non-CHD diagnosis as their initial impression, and those who did not ask for information about the patient’s prior cardiac disease history were the most likely to change their minds. Participants’ certainty in their initial diagnosis, the additional information desired, the diagnostic hypotheses generated, and the follow-up intended were not related to the likelihood of change in diagnostic hypotheses. Discussion While efforts encouraging physicians to avoid cognitive biases and to reason in a more analytic manner may yield some benefit, this study suggests that experience is a more important determinant of diagnostic flexibility than is the consideration of additional diagnoses or the amount of additional information collected.

Cheng-Torres, Kathleen A; Desai, Karan P; Sidhu, Mandeep S; Maron, David J; Boden, William E

2016-01-01

Over the past decade, landmark randomized clinical trials comparing initial management strategies in stable ischemic heart disease (SIHD) have demonstrated no significant reduction in 'hard' end points (all-cause mortality, cardiac death or myocardial infarction) with one strategy versus another. The main advantage derived from early revascularization is improved short-term quality of life. Nonetheless, questions remain regarding how best to manage SIHD patients, such as whether a high-risk subgroup can be identified that may experience a survival or myocardial infarction benefit from early revascularization, and if not, when should diagnostic catheterization and revascularization be performed. The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches trial is designed to address these questions by randomizing SIHD patients with at least moderate ischemia to an initial conservative strategy of optimal medical therapy or an initial invasive strategy of optimal medical therapy plus cardiac catheterization and revascularization.

Clinical experience with the meningococcal B vaccine, Bexsero(®): Prospects for reducing the burden of meningococcal serogroup B disease.

Watson, Philip S; Turner, David P J

2016-02-10

Although rare, invasive meningococcal disease remains an important cause of mortality and morbidity in children and young adults. Vaccines have been successfully introduced to help protect against meningococcal disease caused by serogroups A, C, W and Y, but until recently, a vaccine for serogroup B (MenB) was not available. In many industrialised countries, MenB causes the majority of meningococcal disease. Moreover, MenB outbreaks occur unpredictably, particularly in high-risk populations, such as university students. In 2013, Bexsero(®) became the first broad-coverage vaccine to be licensed for active immunisation against MenB disease. Bexsero is now licensed in more than 35 countries worldwide for varying age groups, including the EU, Australia, Brazil, Canada, Chile, Uruguay and the USA. Clinical recommendations for the use of Bexsero have been published in several countries. Recommendations include use in high-risk groups, outbreak control and routine infant immunisation. Since initial licensure, considerable clinical experience has been gained. In Canada, 43,740 individuals received Bexsero during a vaccination programme in the Saguenay-Lac-Saint-Jean region of Quebec, where local disease incidence was high. In the USA, Bexsero was administered to >15,000 individuals during two college outbreaks prior to licensure, under an Investigational New Drug protocol. In the UK, the Joint Committee on Vaccination and Immunisation has recommended the inclusion of Bexsero in the routine immunisation schedule for infants. Publically funded vaccination programmes have been initiated in Italy, and there has been widespread use of the vaccine outside of publically reimbursed programmes. Overall, >1,000,000 doses of Bexsero have been distributed in 19 countries worldwide since 2013. The emerging clinical experience with Bexsero is consistent with findings from pre-licensure clinical studies, and no new safety concerns have been identified. Additional data on length of protection, potential impact on meningococcal carriage and transmission and strain coverage have also been published and will be reviewed. Copyright © 2015 Elsevier Ltd.

Community pharmacists are well positioned to deliver chronic kidney disease (CKD) screening services. However, little is known about the challenges faced by pharmacists during service implementation. This study aimed to explore community pharmacists' experiences and perceived barriers of implementing a CKD risk assessment service. Data collection was performed by using semistructured, open-ended interview questions. Pharmacists who had implemented a CKD screening service in Tasmania, Australia, were eligible to participate. A purposeful sampling strategy was used to select pharmacists, with variation in demographics and pharmacy location. A conventional content analysis approach was used to conduct the qualitative study. Transcripts were thematically analyzed by using the NVivo 11 software program. Initially, a list of free nodes was generated and data were coded exhaustively into relevant nodes. These nodes were then regrouped to form highly conceptualized themes. Five broad themes emerged from the analysis: contextual fit within community pharmacy; perceived scope of pharmacy practice; customer perception toward disease prevention; CKD - an underestimated disease; and remuneration for a beneficial service. Pharmacists found the CKD service efficient, user-friendly, and of substantial benefit to their customers. However, several pharmacists observed that their customers lacked interest in disease prevention, and had limited understanding of CKD. More importantly, pharmacists perceived the scope of pharmacy practice to depend substantially on interprofessional collaboration between pharmacists and general practitioners, and customer acknowledgment of pharmacists' role in disease prevention. Community pharmacists perceived the CKD service to be worth incorporating into pharmacy practice. To increase uptake, future CKD services should aim to improve customer awareness about CKD before providing risk assessment. Further research investigating strategies to enhance general practitioner involvement in pharmacist-initiated disease prevention services is also needed.

Aggressive treatment of early rheumatoid arthritis: recognizing the window of opportunity and treating to target goals.

PubMed

Resman-Targoff, Beth H; Cicero, Marco P

2010-11-01

Evidence supports the use of aggressive therapy for patients with early rheumatoid arthritis (RA). Clinical outcomes in patients with early RA can improve with a treat-to-target approach that sets the goal at disease remission. The current selection of antirheumatic therapies, including conventional and biologic disease-modifying antirheumatic drugs (DMARDs), has made disease remission a realistic target for patients with early RA. The challenge is selecting the optimal antirheumatic drug or combination of drugs for initial and subsequent therapy to balance the clinical benefits, risks, and economic considerations. In some cases, the use of biologic agents as part of the treatment regimen has shown superior results compared with conventional DMARDs alone in halting the progression of disease, especially in reducing radiographic damage. However, the use of biologic agents as initial therapy is challenged by cost-effectiveness analyses, which favor the use of conventional DMARDs. The use of biologic agents may be justified in certain patients with poor prognostic factors or those who experience an inadequate response to conventional DMARDs as a means to slow or halt disease progression and its associated disability. In these cases, the higher cost of treatment with biologic agents may be offset by decreased societal costs, such as lost work productivity, and increased health-related quality of life. Further research is needed to understand optimal strategies for balancing costs, benefits, and risks of antirheumatic drugs. Some key questions are (1) when biologic agents are appropriate for initial therapy, and (2) when to conclude that response to conventional DMARDs is inadequate and biologic agents should be initiated.

The tyrosine kinase inhibitor (TKI) imatinib has improved outcomes for patients with unresectable or metastatic gastrointestinal stromal tumors (GIST), and for patients receiving adjuvant therapy following GIST resection. This qualitative study explored the experiences and emotions of patients through GIST diagnosis, treatment initiation, disease control, and in some patients, loss of response and therapy switch. Ethnographic investigations were conducted, including semi- structured qualitative interviews of patients with resected or metastatic/unresectable GIST and their caregivers, from Canada (n = 15); the United States (n = 10); and Brazil, France, Germany, Russia, and Spain (n = 5 each). Some interviewees also kept 7-day photo journals. Responses were qualitatively analyzed to identify gaps and unmet needs where communication about disease, treatments, and adherence could be effective. Patients shared common experiences during each stage of disease management (crisis, hope, adaptation, new normal, and uncertainty). Patients felt a sense of crisis during diagnosis, followed by hope upon TKI therapy initiation. Over time, they came to adapt to their new lives (new normal) with cancer. With each follow-up, patients confronted the uncertainty of becoming TKI resistant and the possible need to switch therapy. During uncertainty many patients sought new information regarding GIST. Cases of disease progression and drug switching caused patients to revert to crisis and restart their emotional journey. Patients with primary or unresectable/metastatic GIST shared similar journeys, especially regarding uncertainty, although differences in the scope and timing of phases were observed. Strategies patients used to remain adherent included obtaining family support, setting reminder mechanisms, taking medicine at routine times, and storing medicine in prominent places. Physicians and support staff can manage patient expectations and encourage adherence to therapy, which may facilitate optimal patient outcomes. Patient education about current GIST developments and adherence across all phases of the patient journey are of benefit.

Practical aspects of recruitment and retention in clinical trials of rare genetic diseases: the phenylketonuria (PKU) experience.

2014-02-01

Bringing treatments for rare genetic diseases to patients requires clinical research. Despite increasing activism from patient support and advocacy groups to increase access to clinical research studies, connecting rare disease patients with the clinical research opportunities that may help them has proven challenging. Chief among these challenges are the low incidence of these diseases resulting in a very small pool of known patients with a particular disease, difficulty of diagnosing rare genetic diseases, logistical issues such as long distances to the nearest treatment center, and substantial disease burden leading to loss of independence. Using clinical studies of phenylketonuria as an example, this paper discusses how, based on the authors' collective experience, partnership among clinicians, patients, study coordinators, genetic counselors, dietitians, industry, patient support groups, and families can help overcome the challenges of recruiting and retaining patients in rare disease clinical trials. We discuss specific methods of collaboration, communication, and education as part of a long-term effort to build a community committed to advancing the medical care of patients with rare genetic diseases. By talking to patients and families regularly about research initiatives and taking steps to make study participation as easy as possible, rare disease clinic staff can help ensure adequate study enrollment and successful study completion.

Clinical experience with iodine-123-iodophenylpentadecanoic acid.

Corbett, J

1994-04-01

Initial research in dogs and later research in normal volunteers and patients with coronary artery disease indicated that 123I-iodophenylpentadecanoic acid (IPPA) can provide valuable diagnostic information. This agent compared favorably to 201Tl in detecting stenosed coronary arteries and identified reversible lesions with greater frequency. Testing with both 201Tl and IPPA before and after percutaneous transluminal coronary angioplasty produced similar results, supporting the notion that IPPA deserves inclusion among the diagnostic tools used to evaluate coronary heart disease.

Of all the complications associated with colorectal surgery, the most devastating and constant, despite all techniques being performed properly is anastomotic leakage, especially in left colon and rectal resections with rates as high as 50% when the rectum is involved. In 2005, our center published the preliminary experience with the use of linear staple line reinforcement for colon surgery. The purpose of this paper is to present a series of cases using a new conformation of bioabsorbable reinforcement for circular staplers in 5 patients, 2 patients with rectal cancer, 2 patients with diverticular disease, and 1 patient with sigmoid cancer. These initial data are very promising and has encouraged us to continue using this device on further patients.

Mitral valve regurgitation (MR) is often diagnosed in patients with heart failure and is associated with worsening of symptoms and reduced survival. While surgery remains the gold standard treatment in low-risk patients with degenerative MR, in high-risk patients and in those with functional MR, transcatheter procedures are emerging as an alternative therapeutic option. MitraClip® is the device with which the largest clinical experience has been gained to date, as it offers sustained clinical benefit in selected patients. Further to MitraClip implantation, several additional approaches are developing, to better match with the extreme variability of mitral valve disease. Not only repair is evolving, initial steps towards percutaneous mitral valve implantation have already been undertaken, and initial clinical experience has just started. PMID:23908865

The Obesity Epidemic: Challenges, Health Initiatives, and Implications for Gastroenterologists

Hurt, Ryan T.; Kulisek, Christopher; Buchanan, Laura A.

2010-01-01

Obesity is the next major epidemiologic challenge facing today's doctors, with the annual allocation of healthcare resources for the disease and related comorbidities projected to exceed $150 billion in the United States. The incidence of obesity has risen in the United States over the past 30 years; 60% of adults are currently either obese or overweight. Obesity is associated with a higher incidence of a number of diseases, including diabetes, cardiovascular disease, and cancer. Consumption of fast food, trans fatty acids (TFAs), and fructose—combined with increasing portion sizes and decreased physical activity—has been implicated as a potential contributing factor in the obesity crisis. The use of body mass index (BMI) alone is of limited utility for predicting adverse cardiovascular outcomes, but the utility of this measure may be strengthened when combined with waist circumference and other anthropomorphic measurements. Certain public health initiatives have helped to identify and reduce some of the factors contributing to obesity. In New York City and Denmark, for example, such initiatives have succeeded in passing legislation to reduce or remove TFAs from residents' diets. The obesity epidemic will likely change practice for gastroenterologists, as shifts will be seen in the incidence of obesity-related gastrointestinal disorders, disease severity, and the nature of comorbidities. The experience gained with previous epidemiologic problems such as smoking should help involved parties to expand needed health initiatives and increase the likelihood of preventing future generations from suffering the consequences of obesity.

There is little experience with the effect of pregnancy on Parkinson disease because the number of women with Parkinson disease who are of childbearing age is small. We report four cases beginning during the postpartum period and discuss the potential contribution of different factors that may influence the occurrence of Parkinson disease in this time period. Four women aged 29-35 years developed arm tremor, shoulder pain, dizziness, or decreased dexterity of the hand in the first few days or months after childbirth. They were initially diagnosed with postpartum depression or psychogenic parkinsonism. Finally, dopamine transporter imaging confirmed the diagnosis of young-onset Parkinson disease. Early-onset Parkinson disease may present in postpartum women. In women with atypical motor symptoms in addition to depression, this diagnosis should be considered.

2015-01-01

Aim To report experience with fingolimod in clinical practice. Design/Methods Patients in an academic medical center who were prescribed fingolimod from October 2010 to August 2011 were identified through the electronic medical record and followed for 12 months after fingolimod initiation. Adverse effects, clinical measures, MRI data, and quality of life measures were assessed. Results Three hundred seventeen patients started fingolimod. Eleven patients were treatment naïve (3.5%) and 76 (24.0%) had remote disease modifying therapy use prior to fingolimod. One hundred fifty-one (47.6%) switched because of patient preference and 79 (24.9%) switched because of breakthrough disease. About 11.6% transitioned from natalizumab. Follow-up data were available for 306 patients (96.5%) with mean follow-up time 332 days. Fingolimod was discontinued in 76 of 306 patients (24.8%) at mean 248 days after fingolimod start. Discontinuation most often was due to adverse effects (n=40) or breakthrough disease (n=22). Among patients who started fingolimod with available 12 month follow-up data, 267 (87.3%) remained relapse free and 256 (83.7%) had no relapses or gadolinium enhancement. Time to first relapse occurred at mean 282 days after fingolimod initiation. Quality of life measures remained stable at follow-up. Conclusions Fingolimod was discontinued at a higher rate in clinical practice than in clinical trials. Discontinuation was primarily due to adverse effects or breakthrough disease. Disease activity was adequately controlled in most patients who started fingolimod. This clinical practice cohort is consistent with efficacy data from phase 3 trials and describes the most common tolerability issues in clinical practice. PMID:25271798

Foreign animal disease outbreaks, the animal welfare implications for Canada: Risks apparent from international experience

PubMed Central

Whiting, Terry L.

2003-01-01

Any outbreak of an Office International des Épizooties List A disease, such as classical swine fever or foot and mouth disease, has severe consequences for animal welfare, livestock production, exports of animals and animal products, and the environment. The public concern with the animal welfare effects of methods of disease eradication that result in the destruction of large numbers of uninfected animals has initiated a reconsideration of disease eradication policy in Europe. In many recent List A disease epizootics, the financial cost of addressing animal welfare concerns in healthy animals has greatly exceeded the cost of stamping out disease in infected herds. In the event of a similar incursion in Canada, the number of animals subject to welfare slaughter will be far greater than the number of infected animals killed. Current national disease eradication plans in Canada do not address the animal welfare component of disease control methods. PMID:14601676

Orthopaedic intervention can have a wide range of functional and psychosocial effects on children with neuromuscular disease (NMD). In the multihandicapped child (Gross Motor Classification System IV/V), functional status, pain, psychosocial function, and health-related quality of life also have effects on the families of these child. The purpose of this study is to report the development and initial validation of an outcomes instrument specifically designed to assess the caregiver impact experienced by parents raising severely affected NMD children: the Assessment of Caregiver Experience with Neuromuscular Disease (ACEND). In the first part of this prospective study, 61 children with NMD and their parents were administered a range of earlier validated pediatric health measures. A framework technique was used to select the most appropriate and relevant subset of questions from this large set. Sensitivity analyses guided the development of a master question list measuring caregiver impact, excluding items with low relevance, and modifying unclear questions. In the second part of the study, the ACEND was administered to the caregivers of 46 children with moderate-to-severe NMD. Statistical analyses were conducted to determine validity of the instrument. The resulting ACEND instrument included 2 domains, 7 subdomains, and 41 items. Domain 1, examining physical impact, includes 4 subdomains: feeding/grooming/dressing (6 items), sitting/play (5 items), transfers (5 items), and mobility (7 items). Domain 2, which examines general caregiver impact, included 3 subdomains: time (4 items), emotion (9 items), and finance (5 items). Mean overall relevance rating was 6.21 ± 0.37 and clarity rating was 6.68 ± 0.52 (scale 0 to 7). Multiple floor effects in patients with GMFCS V and ceiling effects in patients with GMFCS III were identified almost exclusively in motor-based items. Virtually no floor or ceiling effects were identified in the time, emotion or finance domains across GMFCS level. The initial validation demonstrated that ACEND is a valid, disease-specific measure to quantify experience on caregivers of children with NMD. Larger groups of patients across NMD disease type are currently being tested to strengthen validity findings. Additionally, the ACEND is now being administered before and after orthopaedic interventions to determine responsiveness, which is critical to health outcomes research.

Initial condition of stochastic self-assembly

NASA Astrophysics Data System (ADS)

Davis, Jason K.; Sindi, Suzanne S.

2016-02-01

The formation of a stable protein aggregate is regarded as the rate limiting step in the establishment of prion diseases. In these systems, once aggregates reach a critical size the growth process accelerates and thus the waiting time until the appearance of the first critically sized aggregate is a key determinant of disease onset. In addition to prion diseases, aggregation and nucleation is a central step of many physical, chemical, and biological process. Previous studies have examined the first-arrival time at a critical nucleus size during homogeneous self-assembly under the assumption that at time t =0 the system was in the all-monomer state. However, in order to compare to in vivo biological experiments where protein constituents inherited by a newly born cell likely contain intermediate aggregates, other possibilities must be considered. We consider one such possibility by conditioning the unique ergodic size distribution on subcritical aggregate sizes; this least-informed distribution is then used as an initial condition. We make the claim that this initial condition carries fewer assumptions than an all-monomer one and verify that it can yield significantly different averaged waiting times relative to the all-monomer condition under various models of assembly.

The 23rd World Scout Jamboree (WSJ) was a 10-day summer camp held in Japan in 2015 under hot and humid conditions. The attendees comprised 33,628 people from 155 countries and territories. The aim of this study was to examine the provision of medical services under such conditions and to identify preventive factors for major diseases among long-term campers. Data were obtained from WSJ medical center records and examined to clarify the effects of age, sex, and period on visit frequencies and rates. Medical records from 3215 patients were examined. Daytime temperatures were 31.5±3.2°C and relative humidity was 61±13% (mean±SD). The initial visit rates among scouts and adults were 72.2 and 77.2 per 1000 persons, respectively. No significant age difference was observed in the initial visit rate; however, it was significantly higher among female patients than male patients. Significant differences were also seen in the adjusted odds ratios by age, sex, and period for disease distributions of initial visit frequencies. In addition, a higher initial visit frequency for heat strain-related diseases was seen among the scouts. Initial visit frequencies for heatstroke and/or dehydration increased just after opening day and persisted until closing day. Our findings suggest the importance of taking effective countermeasures against heat strain, fatigue, and unsanitary conditions at the WSJ. Medical services staff should take attendees' age, sex, and period into consideration to prevent heat strain-related diseases during such camps under hot and humid conditions.

Outpatient management of pelvic inflammatory disease.

PubMed

Price, B; Martens, M

2001-08-01

Pelvic inflammatory disease (PID) is a spectrum of inflammatory disorders of the female genital tract involving at least the endrometrium and may include the fallopian tubes, ovaries, and pelvic cavity. Over 1 million women each year are treated for PID in the United States, and it is one of the most serious infections diagnosed in women due to its sequelae. Women with PID acutely experience pain and are at risk for sepsis; however, the significant increases in ectopic pregnancy and infertility are the most disturbing long-term complications. It most often is initiated with an infection by a sexually transmitted disease, but can also involve a variety of pathogenic aerobes and anaerobes secondarily.

Niemann–Pick type C (NP-C) disease is a rare neurodegenerative lysosomal storage disorder. It is highly heterogeneous, and there is limited awareness of a substantial subgroup that has an attenuated adolescent/adult-onset disease. In these patients psychiatric features, often a psychosis, may dominate the initial impression, although often there is an associated ataxia and cognitive impairment. Typically, patients experience a substantial diagnostic delay. In this review we highlight the importance of early recognition and discuss the pathophysiology, neuropsychiatric presentation and recent changes in the investigation and work-up of these patients, and treatment options.

Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED) was initiated in the first year of the Innovative Medicines Initiative (IMI). It was an ambitious plan to tackle the understanding of asthma through an integration of clinical and multi-'omics approaches that necessitated the bringing together of industry, academic, and patient representatives because it was too large to be managed by any one of the partners in isolation. It was a novel experience for all concerned. In this review, we describe the main features of the U-BIOPRED experience from the industry perspective. We list some of the key advantages and learnings from the perspective of the authors, and also improvements that we feel could be made in future projects. Copyright © 2018 Elsevier Ltd.

In 2007, an outbreak of tuberculosis occurred in a toddler population attending two child care centres in Cork, Ireland. Of 268 children exposed, 18 were eventually diagnosed with active tuberculosis. We present the initial clinical and radiographic characteristics of the active disease group. Mantoux testing was positive in only 66% of cases. All cases were either pulmonary or involved hilar adenopathy on chest radiograph; there were no cases of disseminated disease or meningitis. 24% of the exposed children had been previously vaccinated with BCG, and no case of active disease was found in this group (p = 0.016), suggesting a profound protective effect of BCG in this population. Our experience provides evidence supporting a protective effect of BCG against pulmonary disease in young children.

Treatment of inflammatory bowel disease: what's new in Digestive Disease Week 2016.

PubMed

Chaparro, María

2016-09-01

Inflammatory bowel disease is a chronic disorder of unknown aetiology that results from a pathologic response from both the innate and acquired immune systems, leading to chronic inflammation of the gastrointestinal tract. New drugs have been introduced into the therapeutic armamentarium of inflammatory bowel disease but are not effective in all patients; moreover, among initial responders, there have been reports of loss of response over time. In addition, these drugs sometimes have adverse effects and are often expensive. The present article reviews the studies presented at Digestive Disease Week 2016 that provided new data on the optimisation of currently approved treatments for inflammatory bowel disease, experience with recently approved drugs in clinical practice, and some studies on molecules that are under development for the treatment of these diseases.

Freezing of gait (FOG) remains one of the most common debilitating aspects of Parkinson's disease and has been linked to injuries, falls and reduced quality of life. Although commercially available portable cueing devices exist claiming to assist with overcoming freezing; their immediate effectiveness in overcoming gait initiation failure is currently unknown. This study investigated the effects of three different types of cueing device in people with Parkinson's disease who experience freezing. Twenty participants with idiopathic Parkinson's disease who experienced freezing during gait but who were able to walk short distances indoors independently were recruited. At least three attempts at gait initiation were recorded using a 10 camera Qualisys motion analysis system and four force platforms. Test conditions were; Laser Cane, sound metronome, vibrating metronome, walking stick and no intervention. During testing 12 of the 20 participants had freezing episodes, from these participants 100 freezing and 91 non-freezing trials were recorded. Clear differences in the movement patterns were seen between freezing and non-freezing episodes. The Laser Cane was most effective cueing device at improving the forwards/backwards and side to side movement and had the least number of freezing episodes. The walking stick also showed significant improvements compared to the other conditions. The vibration metronome appeared to disrupt movement compared to the sound metronome at the same beat frequency. This study identified differences in the movement patterns between freezing episodes and non-freezing episodes, and identified immediate improvements during gait initiation when using the Laser Cane over the other interventions.

Though vedolizumab has received regulatory approval for the treatment of Crohn's disease (CD) and ulcerative colitis (UC) in adults, there is increasing off-label use in children. To describe the experience with vedolizumab in pediatric inflammatory bowel disease (IBD) patients at 3 tertiary IBD centers and examine predictors of remission. A retrospective review identified pediatric IBD patients (age < 18 yrs) receiving vedolizumab. Data on demographics, disease behavior, location, activity, and previous treatments/surgeries were collected. Disease activity was assessed using the weighted pediatric CD activity index or pediatric UC activity index. Primary outcome was week 14 remission, defined as pediatric UC activity index <10 or weighted pediatric CD activity index <12.5. Descriptive statistics and univariate analyses were performed to examine associations of clinical characteristics with efficacy. Fifty-two patients, 58% CD and 42% UC, initiated vedolizumab between June 2014 and August 2015. Median age at vedolizumab initiation was 14.9 (range 7-17) years. Ninety percent had failed ≥1 anti-tumor necrosis factor (TNF) agent. Week 14 remission rates for UC and CD were 76% and 42%, respectively (P < 0.05). Eighty percent of anti-TNF-naive patients experienced week 14 remission. At week 22, anti-TNF-naive patients had higher remission rates than TNF-exposed patients (100% versus 45%, P = 0.04). There were no infusion reactions or serious adverse events/infections. Our results suggest that vedolizumab is efficacious and safe in pediatric IBD patients, with UC patients experiencing earlier and higher rates of remission than CD patients. Anti-TNF-naive patients experienced higher remission rates than those with anti-TNF exposure. Controlled clinical trial data are needed to confirm these observations.

Dialysis can be very stressful with the initial months onto treatment being highly critical in terms of both adaptation and mortality. This qualitative study aimed to explore the lived experiences of incident haemodialysis patients in Singapore. Topics related to the end-stage renal disease diagnosis and haemodialysis treatment were raised with 13 incident haemodialysis patients in the form of semi-structured interviews, and interpretative phenomenological analysis was undertaken as the framework for data analysis. Emotional distress, treatment-related concerns and social support emerged as main issues following a critical review of themes. Our study revealed that incident haemodialysis patients have emotional and informational needs, highlighting the importance of intervention programmes in particular to this patient group to promote better psychosocial adjustment to the disease and its treatment.

Objectives To explore what it means for patients to live with chronic obstructive pulmonary disease (COPD) as an incurable and constantly progressing disease. Design Qualitative longitudinal study using narrative and semistructured interviews. This paper presents findings of the initial interviews. Analysis using grounded theory. Setting Lung care clinics and community care in Lower Saxony, Germany. Participants 17 patients with advanced-stage COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) III/IV). Findings Analysis shows that these patients have difficulties accepting their life situation and feel at the mercy of the disease, which could be identified as a core-experienced phenomenon. Over a long period of time, patients have only a vague feeling of being ill, caused by uncertain knowledge, slow progress and doubtful attribution of clinical symptoms of the disease (causal conditions). As an action strategy, patients try to maintain daily routines for as long as possible after diagnosis. Both effective standard and rescue medication, which helps to reduce breathlessness and other symptoms, and the feeling of being faced with one's own responsibility (intervening conditions) support this strategy, whereby patients' own responsibility is too painful to acknowledge. As a consequence, patients try to deny the threat to life for a long period of time. Frequently, they need to experience facing their own limits, often in the form of an acute crisis, to realise their health situation. The experience of the illness is contextualised by a continuous increase in limited mobility and social isolation. Conclusion In order to help patients to improve disease awareness, to accept their life situation and to improve their reduced quality of life, patients may benefit from the early integration of palliative care (PC), considering its multiprofessional patient-centred and team-centred approach. Psychological support and volunteer work, which are relevant aspects of PC, should be appropriate to address psychosocial needs. More research is needed to evaluate how patients could benefit from early PC. PMID:27932338

[Initial experience in robot-assisted colorectal surgery in Mexico].

Villanueva-Sáenz, Eduardo; Ramírez-Ramírez, Moisés Marino; Zubieta-O'Farrill, Gregorio; García-Hernández, Luis

Colorectal surgery has advanced notably since the introduction of the mechanical suture and the minimally invasive approach. Robotic surgery began in order to satisfy the needs of the patient-doctor relationship, and migrated to the area of colorectal surgery. An initial report is presented on the experience of managing colorectal disease using robot-assisted surgery, as well as an analysis of the current role of this platform. A retrospective study was conducted in order to review five patients with colorectal disease operated using a robot-assisted technique over one year in the initial phase of the learning curve. Gender, age, diagnosis and surgical indication, surgery performed, surgical time, conversion, bleeding, post-operative complications, and hospital stay, were analysed and described. A literature review was performed on the role of robotic assisted surgery in colorectal disease and cancer. The study included 5 patients, 3 men and 2 women, with a mean age of 62.2 years. Two of them were low anterior resections with colorectal primary anastomoses, one of them extended with a loop protection ileostomy, a Frykman-Goldberg procedure, and two left hemicolectomies with primary anastomoses. The mean operating time was 6hours and robot-assisted 4hours 20minutes. There were no conversions and the mean hospital stay was 5 days. This technology is currently being used worldwide in different surgical centres because of its advantages that have been clinically demonstrated by various studies. We report the first colorectal surgical cases in Mexico, with promising results. There is enough evidence to support and recommend the use of this technology as a viable and safe option.

The study aimed to explore patients' experience of living with chronic obstructive pulmonary disease and their perspective of their community healthcare for chronic obstructive pulmonary disease to extract affective responses in order to develop potential items for a patient-reported experience measure for chronic obstructive pulmonary disease. Qualitative face-face interviews were conducted, in the community, with 64 patients with chronic obstructive pulmonary disease recruited from General Practices and Breathe-Easy community groups in the Outer North East, East and City areas of London and Essex, UK. A two phase analysis of the qualitative data was conducted to identify themes arising from patients' description of living with chronic obstructive pulmonary disease and their perceptions of their community healthcare and subsequently the affective responses underlying the themes raised by patients, which gave emotional colour to the themes, bringing the thematic analysis closer to the subjective patient experience. Five themes were identified from the interview data: 'Journey to diagnosis'; 'Smoking'; 'Usual care'; 'My everyday life'; and 'Exacerbations'. Twenty-one affective responses were identified and categorised as either 'negative', 'positive' or 'bivalent'. 'Frustration', a negative affective response was prevalent in four themes. 'Gratitude', 'hope' and 'happiness/enjoyment' were among the more positive responses more prevalent across several themes. By conducting a novel two-way analysis (thematic and affective) it was possible to identify themes and affective responses that were aligned to those themes. This enabled the development of 38 chronic obstructive pulmonary disease-specific experience items to take forward for further testing including item reduction and validity and reliability in the next stage of the patient-reported experience measure development. GIVING IMPORTANCE TO PATIENTS' EMOTIONS: An exploration of patient perceptions of living with chronic lung disease will help develop a new patient reported experience scale. Healthcare services are aiming to provide effective patient-centered care for those with chronic obstructive pulmonary disease (COPD). Such care strategies require structured, validated patient feedback scales to facilitate accurate communication between patients, carers and healthcare professionals. Susan Walker at Anglia Ruskin University in Chelmsford, UK, and co-workers analyzed qualitative data from interviews with 64 COPD patients in London and Essex regarding their emotions and perceptions of living with COPD, with the aim of creating a patient reported experience measure, or PREM. Initial results identified five themes-including 'journey to diagnosis' and 'everyday life'-and twenty-one affective responses, ranging from negative to positive. The team will take these results forward for further validation.

Severe colitis flare from ulcerative colitis (UC) or Crohn's disease (CD) may be refractory to corticosteroids and antitumour necrosis factor (TNF) agents resulting in high colectomy rates. We aimed to describe the utility of tacrolimus to prevent colectomy during second-line vedolizumab initiation after corticosteroid and anti-TNF treatment failure in paediatric severe colitis. A retrospective cohort analysis was performed between 1 October 2014 and 31 October 2016 at a single tertiary care centre. Inclusion criteria were patients with severe colitis who received tacrolimus before or during vedolizumab induction and previous exposure to anti-TNF therapy with or without corticosteroids. The initiation of tacrolimus was clinician dependent based on an institutional protocol. Twelve patients (10 UC, two CD; median age 16 years; three female) received at least one dose of vedolizumab 10 mg/kg (max of 300 mg) due to anti-TNF therapy failure and persistent flare not responsive to corticosteroids. Of the 12 patients, eight (67%) and four (33%) had failed one or two anti-TNF agents, respectively. Tacrolimus was initiated for acute disease severity during hospitalisation (58%) or ongoing flare during outpatient care (42%). 9 (75%) of 12 patients avoided colectomy or inflammatory bowel disease-related surgery at 24 weeks and eight (68%) continued on vedolizumab maintenance with no adverse events out to 80 weeks. We report real-world data on the outcome of tacrolimus around vedolizumab initiation in paediatric UC or CD after corticosteroid and anti-TNF therapy treatment failure. Our pilot experience indicates a potential benefit of concomitant tacrolimus when initiating vedolizumab therapy.

The Ebola virus disease outbreak that initially hit Guinea, Liberia and Senegal in 2014 was projected to affect Nigeria very badly when the first case was reported in July 2014. However, the outbreak was effectively and swiftly contained with only eight deaths out of 20 cases, confounding even the most optimistic predictions of the disease modelers. A combination of health worker and public education, a coordinated field epidemiology and laboratory training program (with prior experience in disease outbreak control in other diseases) and effective set-up of emergency operations centers were some of the measures that helped to confound the critics and contain what would have been an otherwise deadly outbreak in a densely populated country with a highly mobile population. This article highlights the measures taken in Nigeria and looks to the translatable lessons learnt for future disease outbreaks, whether that be from the Ebola virus or other infectious agents.

Clustered tuberculosis (TB) still occurred nationally in Chinese schools every year, where high school students patients accounts for the highest proportion. These young TB patients are in a critical period of physical and psychological growth. Research on their illness experience and analysis of underlying causes remains blank. The purpose of this study is to explore the overall illness experience of Chinese high school TB patients and to investigate the individual and social causes of such experience. Twenty-two high school TB patients in a certain county of Shaanxi province were interviewed in-depth twice when initial diagnosed and during intermediate treatment periods. Interview data were analyzed by framework approach. The high school TB patients worried about interruption of studies rather than the disease. They generally showed a lack of awareness of tuberculosis, were highly dependent on parents, and received assistance from teachers and students during the treatment. Most of them did not show obvious stigma. The unique education system and sociocultural factors in China are the root of special illness experience of high school TB patients. Huge pressure in college entrance examination leads sick students to worry about interruption of studies more than the disease itself. Their serious lack of awareness of TB, caused by the ignorance of school, parents and the students, becomes the biggest obstacle to timely diagnosis and treatment. Whether high dependence on parents is conducive to disease recovery varies with each individual. Meanwhile, patients' weak stigma could play a positive role in disease recovery. Educational and medical institutions should develop more effective TB control strategies based on these factors.

Mitigation of disease- and treatment-related risks in patients with psoriatic arthritis.

Psoriatic arthritis is a part of the family of diseases referred to as spondyloarthropathies, a diverse group of chronic inflammatory disorders with common clinical, radiographic, and genetic features. Peripheral arthritis is the most common symptom of psoriatic arthritis and patients also frequently experience involvement of the entheses, spine, skin, and nails. Due to the diverse clinical spectrum of disease severity, tissues affected, and associated comorbidities, the treatment of psoriatic arthritis can be challenging and it is necessary to mitigate risks associated with both the disease and its treatment. These risks include disease-specific, treatment-related, and psychological risks. Disease-specific risks include those associated with disease progression that can limit functional status and be mitigated through early diagnosis and initiation of treatment. Risks also arise from comorbidities that are associated with psoriatic arthritis such as cardiovascular disease, obesity, diabetes mellitus, and gastrointestinal inflammation. Patient outcomes can be affected by the treatment strategy employed and the pharmacologic agents administered. Additionally, it is important for physicians to be aware of risks specific to each therapeutic option. The impact of psoriatic arthritis is not limited to the skin and joints and it is common for patients to experience quality-of-life impairment. Patients are also more likely to have depression, anxiety, and alcoholism. This article reviews the many risks associated with psoriatic arthritis and provides guidance on mitigating these risks.

2012-01-01

Purpose The tyrosine kinase inhibitor (TKI) imatinib has improved outcomes for patients with unresectable or metastatic gastrointestinal stromal tumors (GIST), and for patients receiving adjuvant therapy following GIST resection. This qualitative study explored the experiences and emotions of patients through GIST diagnosis, treatment initiation, disease control, and in some patients, loss of response and therapy switch. Patients and methods Ethnographic investigations were conducted, including semi- structured qualitative interviews of patients with resected or metastatic/unresectable GIST and their caregivers, from Canada (n = 15); the United States (n = 10); and Brazil, France, Germany, Russia, and Spain (n = 5 each). Some interviewees also kept 7-day photo journals. Responses were qualitatively analyzed to identify gaps and unmet needs where communication about disease, treatments, and adherence could be effective. Results Patients shared common experiences during each stage of disease management (crisis, hope, adaptation, new normal, and uncertainty). Patients felt a sense of crisis during diagnosis, followed by hope upon TKI therapy initiation. Over time, they came to adapt to their new lives (new normal) with cancer. With each follow-up, patients confronted the uncertainty of becoming TKI resistant and the possible need to switch therapy. During uncertainty many patients sought new information regarding GIST. Cases of disease progression and drug switching caused patients to revert to crisis and restart their emotional journey. Patients with primary or unresectable/metastatic GIST shared similar journeys, especially regarding uncertainty, although differences in the scope and timing of phases were observed. Strategies patients used to remain adherent included obtaining family support, setting reminder mechanisms, taking medicine at routine times, and storing medicine in prominent places. Conclusions Physicians and support staff can manage patient expectations and encourage adherence to therapy, which may facilitate optimal patient outcomes. Patient education about current GIST developments and adherence across all phases of the patient journey are of benefit. PMID:22536061

Patients' experiences of an open access follow up arrangement in managing inflammatory bowel disease

Rogers, A; Kennedy, A; Nelson, E; Robinson, A

2004-01-01

Background: Improving access is a key policy issue in improving quality of care and extending patient choice and participation. People's experience of changing from fixed outpatient appointments to more flexible direct access arrangements for chronic disease has been underexplored. Objectives: To examine patients' views on using an open system of access compared with fixed outpatient appointments as part of a guided self-management intervention for inflammatory bowel disease (IBD). Design: Embedded qualitative study undertaken alongside a randomised controlled trial. Semi-structured interviews were undertaken to obtain an in depth understanding of patients' experience of the change in access arrangements. Participants: A purposive sample (n = 30) was drawn from the intervention group (n = 700) according to a range of responses to the trial baseline and follow up quantitative measures. Results: 28 interviews were included in the analysis. Compared with the previous system of fixed appointments, preference for the new open access system was based on enhanced personal control in contacting services and the view that it fitted better with everyday routine management and the requirement for urgent medical contact when symptoms fail to respond to medication. Preference for retaining fixed appointments was based on a sense of security from gaining access which did not require the individual to initiate the request for medical help. Conclusions: Open access may fit better with patients' self-management of their condition and everyday routines, roles and responsibilities. Ensuring that outpatient organisational arrangements and personnel are responsive to patient initiated requests for appointments is likely to impact on the acceptability of this type of access arrangement. Some people may continue to prefer the fixed appointment system which should be retained if patient choice is to be respected. PMID:15465941

Living with advanced Parkinson's disease: a constant struggle with unpredictability.

This paper is a report of an exploration of patients' lifeworld and way of managing life with advanced Parkinson's disease prior to Deep Brain Stimulation and what they expect from life following this treatment. Parkinson's disease is a progressive neurodegenerative disease, which is initially well-treated with L-dopa. Living with Parkinson's disease means living with the experience of continuous loss of independence and self-esteem and unpredictable ON/OFF phenomena. Thus, in the advanced stage of the disease, treatment with Deep Brain Stimulation may become relevant. Eleven patients eligible for Deep Brain Stimulation were interviewed prior to treatment. Data were collected in 2007 and analysed according to the hermeneutic phenomenological methodology of van Manen, using the four existentials as analytic tools. Living with advanced Parkinson's disease can be described as the experience of living with and managing unpredictability. The disease gradually took over, and participants had to struggle with unpredictability on a daily basis. Themes in relation to this were: The body - setting the agenda, Always a struggle to be on time, Living in dependence and compromise - being a burden, and Living with restrained space and changes in social life. Parkinson's disease leads to profound bodily restrictions. Living with an unpredictable body affects all aspects of life, and nurses need to be aware of the impact the disease has on the entire lifeworld, and how this may affect the way treatment is perceived. © 2010 Blackwell Publishing Ltd.

Having adequate numbers of qualified human resources for health is essential for any effective health care system. However, there is a global shortage of skilled health care workers, especially in Sub-Saharan African countries. This shortage is exacerbated by a disproportionately high rate of infectious diseases, the burden of emerging chronic, noncommunicable diseases, and the emigration of medical doctors. Botswana has also experienced this critical shortage of doctors for many years. To address the shortage, the country in the 1990 s embarked on an aggressive program to train its students at foreign medical schools. Despite intensified training, many graduates have not returned. As a result, the country decided to establish a medical school within Botswana. The newly established school was awarded a grant from the Medical Education Partnership Initiative, which has helped to accelerate the school's development. This paper describes the authors' experiences, highlighting curriculum, staffing, infrastructure approaches, key successes, and challenges encountered. The paper concludes by proposing solutions. The authors' experiences and the lessons learned can inform colleagues in other countries considering similar endeavors.

We report results of the initial experience with magnetic resonance image (MRI)-guided implantation of subthalamic nucleus (STN) deep brain stimulating (DBS) electrodes at the University of Wisconsin after having employed frame-based stereotaxy with previously available MR imaging techniques and microelectrode recording for STN DBS surgeries. Ten patients underwent MRI-guided DBS implantation of 20 electrodes between April 2011 and March 2013. The procedure was performed in a purpose-built intraoperative MRI suite configured specifically to allow MRI-guided DBS, using a wide-bore (70 cm) MRI system. Trajectory guidance was accomplished with commercially available system consisting of an MR-visible skull-mounted aiming device and a software guidance system processing intraoperatively acquired iterative MRI scans. A total of 10 patients (5 male, 5 female)-representative of the Parkinson Disease (PD) population-were operated on with standard technique and underwent 20 electrode placements under MRI-guided bilateral STN-targeted DBS placement. All patients completed the procedure with electrodes successfully placed in the STN. Procedure time improved with experience. Our initial experience confirms the safety of MRI-guided DBS, setting the stage for future investigations combining physiology and MRI guidance. Further follow-up is required to compare the efficacy of the MRI-guided surgery cohort to that of traditional frame-based stereotaxy. Copyright © 2014 Elsevier B.V. All rights reserved.

Dance for Individuals With Dementia.

Lapum, Jennifer L; Bar, Rachel J

2016-03-01

The movement and music associated with dance plays an important role in many individuals' lives and can become imprinted upon the body and mind. Dance is thus closely associated with memory because of these deep connections. Without conscious thought, dance has the potential to be initiated as individuals age. In the current article, the authors share narrative reflections about their experiences with, and the potential of, dance as an intervention for aging populations diagnosed with dementia-related diseases. They draw upon their experiences in working with the aging population and a dance program currently being developed by Canada's National Ballet School and Baycrest Health Sciences for individuals with dementia-related diseases in long-term care. The current article is structured as dialogue between the authors because it mimics dance as a dialogical encounter between movement and music, and/or between individuals.

Initiatives to hasten the translation of basic science discoveries to clinical care have necessitated the development of new approaches to interdisciplinary collaboration and training of future investigators. This has been nowhere more important than in the study of sex differences with implications for extension into areas of gender medicine. Clearly, gaining better understanding of the role that sex and gender play in health and disease is essential to the implementation of truly individualized medicine. This case report will describe our experiences in developing the Mayo Clinic Building Interdisciplinary Research Programs in Women's Health (BIRCWH) program, an interdisciplinary research and training program in women's health and sex and gender differences. We identify both our successes and the barriers we have encountered in order that others who are developing similar programs might benefit from our experiences.

Clinical and Cost Implications of Universal Versus Locally Advanced-Stage and Advanced-Stage-Only Molecular Testing for Epidermal Growth Factor Receptor Mutations and Anaplastic Lymphoma Kinase Rearrangements in Non-Small Cell Lung Carcinoma: A Tertiary Academic Institution Experience.

PubMed

Sauter, Jennifer L; Butnor, Kelly J

2016-04-01

Although epidermal growth factor receptor (EGFR)- and anaplastic lymphoma kinase (ALK)-directed therapies are not approved for patients with early-stage non-small cell lung carcinoma (NSCLC), many institutions perform EGFR and ALK testing for all patients with NSCLC at the time of initial diagnosis. Current consensus guidelines recommend EGFR testing and suggest ALK testing at the time of initial diagnosis for patients with advanced disease. To examine the cost and clinical impact of EGFR and ALK testing of patients with early-stage NSCLC. Records from all patients with a diagnosis of NSCLC made on a nonresection specimen at our institution during a single calendar year (2012) were reviewed, and a cost analysis was performed. Of 133 total patients, 47 (35%) had early-stage (stage I or II) disease and 86 (65%) had locally advanced (stage III) or advanced (stage IV) disease at presentation. Eight of 47 patients with early-stage disease (17%) had progression/recurrence during 18 to 30 months of follow-up, 6 of 8 (75%) of whom had pathologic confirmation of progression/recurrence. The estimated additional cost of EGFR and ALK testing for all newly diagnosed patients with NSCLC at our institution is $75,200 per year, compared to testing only patients with locally advanced and advanced-stage disease. The cost of universal molecular testing of NSCLC is substantial. EGFR and ALK testing of patients with early-stage disease appears to have negligible clinical impact, as most patients do not have disease recurrence/progression. Those whose disease recurs/progresses typically undergo rebiopsy. Our findings do not support the practice of universal EGFR and ALK testing in NSCLC at the time of initial diagnosis.

Of children with idiopathic nephrotic syndrome, 10%–20% fail to respond to steroids or develop secondary steroid resistance (termed initial steroid sensitivity) and the majority progress to transplantation. Although 30%–50% of these patients suffer disease recurrence after transplantation, with poor long-term outcome, no reliable indicator of recurrence has yet been identified. Notably, the incidence of recurrence after transplantation appears reduced in patients with steroid-resistant nephrotic syndrome (SRNS) due to monogenic disorders. We reviewed 150 transplanted patients with SRNS to identify biomarkers that consistently predict outcome of SRNS after transplantation. In all, 25 children had genetic or familial SRNS and did not experience post-transplant recurrence. We reviewed phenotypic factors, including initial steroid sensitivity, donor type, age, ethnicity, time to ESRD, and time on dialysis, in the remaining 125 children. Of these patients, 57 (45.6%) developed post-transplant recurrence; 26 of 28 (92.9%) patients with initial steroid sensitivity recurred after transplantation, whereas only 26 of 86 (30.2%) patients resistant from the outset recurred (odds ratio, 30; 95% confidence interval, 6.62 to 135.86; P<0.001). We were unable to determine recurrence in two patients (one with initial steroid sensitivity), and nine patients did not receive initial steroids. Our data show that initial steroid sensitivity is highly predictive of post-transplant disease recurrence in this pediatric patient population. Because a pathogenic circulating permeability factor in nephrotic syndrome remains to be confirmed, we propose initial steroid sensitivity as a surrogate marker for post-transplant recurrence.

Living with multiple chronic diseases is complex and leads to enhanced care needs. To foster integrated care a project called "Living with chronic disease" (Leila) was initiated. The aim was to develop an Advanced Practice Nursing (APN) service in collaboration with medical centers for persons who are living with multiple chronic diseases. The following research questions were addressed: 1. What are patients' experiences, referring physicians and APNs with the Leila-Service? 2. How are referral processes performed? 3. How do the involved groups experience collaboration and APN role development? A qualitative approach according grounded theory of Corbin and Strauss was used to explore the experiences with the Leila project and the interaction of the persons involved. 38 interviews were conducted with patients who are living with multiple chronic diseases, their APN's and the referring physicians. The findings revealed "Being cared for and caring" as main category. The data demonstrated how patients responded to their involvement into care and that they were taken as serious partners in the care process. The category "organizing everyday life" describes how patients learned to cope with the consequences of living with multiple chronic diseases. "Using all resources" as another category demonstrates how capabilities and strengths were adopted. The results of the cooperation- and allocation processes showed that the APN recognition and APN role performance have to be negotiated. Prospective APN-services for this patient population should be integrated along with physician networks and other service providers including community health nursing.

Emerging infectious diseases are a key threat to wildlife. Several fungal skin pathogens have recently emerged and caused widespread mortality in several vertebrate groups, including amphibians, bats, rattlesnakes and humans. White-nose syndrome, caused by the fungal skin pathogen Pseudogymnoascus destructans, threatens several hibernating bat species with extinction and there are few effective treatment strategies. The skin microbiome is increasingly understood to play a large role in determining disease outcome. We isolated bacteria from the skin of four bat species, and co-cultured these isolates with P. destructans to identify bacteria that might inhibit or kill P. destructans. We then conducted two reciprocal challenge experiments in vitro with six bacterial isolates (all in the genus Pseudomonas) to quantify the effect of these bacteria on the growth of P. destructans. All six Pseudomonas isolates significantly inhibited growth of P. destructans compared to non-inhibitory control bacteria, and two isolates performed significantly better than others in suppressing P. destructans growth for at least 35 days. In both challenge experiments, the extent of suppression of P. destructans growth was dependent on the initial concentration of P. destructans and the initial concentration of the bacterial isolate. These results show that bacteria found naturally occurring on bats can inhibit the growth of P. destructans in vitro and should be studied further as a possible probiotic to protect bats from white-nose syndrome. In addition, the presence of these bacteria may influence disease outcomes among individuals, populations, and species.

Patient-initiated action plans are an important component of COPD self-management (SM) interventions. When integrated into SM interventions, these action plans have proven to be effective in reducing exacerbation severity, hospitalisations, and costs and in improving health status in patients with COPD without severe comorbidities. Because of overlap in symptoms, a self-treatment (ST) approach that focuses solely on traditional symptoms of COPD is inadequate for patients with COPD and comorbidities. The COPE-III SM intervention combines (I) patient-initiated action plans that are tailored to the individual's co-morbid disease(s), and (II) ongoing nurse support. In this paper we provide information regarding the integration of information from two previous COPD SM studies (COPE I and II) in the development of the current COPE-III ST approach. COPE-III ST materials include daily symptom diaries and action plans that take patient's common comorbidities [chronic heart failure (CHF), anxiety, depression, ischaemic heart disease (IHD), and diabetes] into account. The comorbid diary and action plans components were developed in collaboration with multiple disease-experts. Previous SM studies have highlighted some essential topics that need to be considered when developing a SM or ST approach: 'when to initiate ST', 'how to optimize materials and safety', and 'how to achieve behavioural change'. In the COPE-III study, ST is initiated after a significant change in symptoms. This is consistent with the COPE-II approach and was implemented because disease symptoms are often present even when patients are stable. We have tried to ensure patient safety by providing an easily accessible case-manager to patients throughout their involvement in the study. Furthermore, a psychologist has ensured the use of behavioural change techniques throughout the intervention. We should continue to learn from our experiences with SM interventions to further optimize future SM and ST interventions. The use of materials that are suitable for different levels of patient literacy and the training of health care providers are other points of improvement.

To present the initial experience and preliminary clinical results of patients treated mainly with proton irradiation at the newly developed proton therapy facility at Shizuoka Cancer Center. We reviewed 125 patients who underwent proton therapy between July 2003 and December 2004. Of these 125 patients, 11 had head and neck malignancies, 15 non-small cell lung cancers, 22 hepatocellular carcinomas, 62 prostate cancers, and 15 other malignant tumors. Most patients experienced Grade 0-1 acute morbidities (NCI-CTC) in skin or mucosa, while a temporary Grade 2-3 reaction was observed in a high dose area. Response rates were 73% for H & N malignancies, 100% for NSCLC, and 77% for HCC. PSA evaluation for patients with prostate cancer revealed a high rate of complete response. The efficacy and safety of proton therapy at Shizuoka Cancer Center was demonstrated for patients with early-stage cancer or locally advanced disease.

This paper introduces WiiPD, an approach to home-based objective assessment of Parkinson's disease. WiiPD aims to make use of the many capabilities of the Nintendo Wii Remote in combination with a number of bespoke data gathering methods to provide a rich and engaging user experience that can capture a wide range of motor and non-motor metrics. In this paper we discuss the architecture of the approach, and provide details of the implementation and testing of the motor-assessment component of the system. Initial results of testing on 6 users indicate that the system is able to differentiate between normal and abnormal motor performance, suggesting that the system has the potential to monitor the motor fluctuations associated with Parkinson's disease.

Differentiating disease subtypes by using pathway patterns constructed from gene expressions and protein networks.

Gene expression profiles differ in different diseases. Even if diseases are at the same stage, such diseases exhibit different gene expressions, not to mention the different subtypes at a single lesion site. Distinguishing different disease subtypes at a single lesion site is difficult. In early cases, subtypes were initially distinguished by doctors. Subsequently, further differences were found through pathological experiments. For example, a brain tumor can be classified according to its origin, its cell-type origin, or the tumor site. Because of the advancements in bioinformatics and the techniques for accumulating gene expressions, researchers can use gene expression data to classify disease subtypes. Because the operation of a biopathway is closely related to the disease mechanism, the application of gene expression profiles for clustering disease subtypes is insufficient. In this study, we collected gene expression data of healthy and four myelodysplastic syndrome subtypes and applied a method that integrated protein-protein interaction and gene expression data to identify different patterns of disease subtypes. We hope it is efficient for the classification of disease subtypes in adventure.

Veno-occlusive disease (VOD) of the liver is a well-recognized serious complication of hematopoietic stem cell transplantation (HSCT), with few successful treatment modalities available for severe disease. Some reports have demonstrated success in adults with the use of high-dose steroid therapy, but experience in the pediatric population is lacking. We retrospectively reviewed HSCT patients treated at our institution since 2003 and identified 15 (2.4%) who developed VOD. Of these, nine (60%) were treated with intravenous high-dose methylprednisolone (500 mg/m2 per dose every 12 hours for six doses). Steroid therapy was initiated at or before first ultrasound evidence of reversal of portal venous flow and before meeting criteria for initiation of defibrotide therapy. Four patients were also treated with defibrotide starting 2 to 5 days after initiation of steroids. Eight of nine patients (88%) with VOD were diagnosed with multiorgan failure. Response to high-dose steroid therapy as defined by decrease in bilirubin by 50% in 10 days from therapy initiation was noted in six of nine patients (67%), occurring within 3 to 6 days of steroid therapy. Two patients died from multiorgan failure due to VOD. Seven survivors of VOD recovered at the median 6 days (range, 5 to 38) from VOD diagnosis. Overall, VOD survival as a group was 78%; however, survival among responders was 100%. No serious toxicities related to high-dose steroid therapy were observed. We conclude that high-dose steroid therapy if initiated early may reverse VOD of the liver in pediatric HSCT patients, abrogating the need for defibrotide therapy with its associated toxicities and regulatory difficulties.

Objectives  To demonstrate the initial experience of robotic hysterectomy to treat benign uterine disease at a university hospital in Brazil. Methods  A cross-sectional study was conducted to review data from the first twenty patients undergoing robotic hysterectomy at our hospital. The surgeries were performed from November 2013 to August 2014, all of them by the same surgeon. The patients were reviewed for preoperative characteristics, including age, body mass index (BMI), indications for the hysterectomy and previous surgeries. Data of operative times, complications, postoperative pain and length of hospital stay were also collected. Results  The total operating room time was 252.9 minutes, while the operative time was 180.7 minutes and the console time was 136.6 minutes. Docking time was 4.2 minutes, and the average undocking time was 1.9 minutes. There was a strong correlation between the operative time and the patient's BMI ( r  = 0.670; p  = 0.001). The console time had significant correlation with the uterine weight and the patient's BMI ( r  = 0.468; p  = 0.037). A learning curve was observed during docking and undocking times. Conclusion  Despite its high cost, the robotic surgery is gaining more space in gynecological surgery. By the results obtained in our hospital, this surgical proposal proved to be feasible and safe. Our initial experience demonstrated a learning curve in some ways. Thieme Publicações Ltda Rio de Janeiro, Brazil.

An important problem in modern therapeutics at the proteomic level remains to identify therapeutic targets in a plentitude of high-throughput data from experiments relevant to a variety of diseases. This paper presents the application of novel modern control concepts, such as pinning controllability and observability applied to the glioma cancer stem cells (GSCs) protein graph network with known and novel association to glioblastoma (GBM). The theoretical frameworks provides us with the minimal number of "driver nodes", which are necessary, and their location to determine the full control over the obtained graph network in order to provide a change in the network's dynamics from an initial state (disease) to a desired state (non-disease). The achieved results will provide biochemists with techniques to identify more metabolic regions and biological pathways for complex diseases, to design and test novel therapeutic solutions.

Fabry disease results from deficient α-galactosidase A activity and globotriaosylceramide accumulation causing renal insufficiency, strokes, hypertrophic cardiomyopathy and early demise. We assessed the 10-year outcome of recombinant α-galactosidase A therapy. The outcomes (severe clinical events, renal function, cardiac structure) of 52/58 patients with classic Fabry disease from the phase 3 clinical trial and extension study, and the Fabry Registry were evaluated. Disease progression rates for patients with low renal involvement (LRI, n=32) or high renal involvement (HRI, n=20) at baseline were assessed. 81% of patients (42/52) did not experience any severe clinical event during the treatment interval and 94% (49/52) were alive at the end of the study period. Ten patients reported a total of 16 events. Patients classified as LRI started therapy 13 years younger than HRI (mean 25 years vs 38 years). Mean slopes for estimated glomerular filtration rate for LRI and HRI were -1.89 mL/min/1.73 m(2)/year and -6.82 mL/min/1.73 m(2)/year, respectively. Overall, the mean left ventricular posterior wall thickness and interventricular septum thickness remained unchanged and normal. Patients who initiated treatment at age ≥ 40 years exhibited significant increase in left ventricular posterior wall thickness and interventricular septum thickness. Mean plasma globotriaosylceramide normalised within 6 months. This 10-year study documents the effectiveness of agalsidase beta (1 mg/kg/2 weeks) in patients with Fabry disease. Most patients remained alive and event-free. Patients who initiated treatment at a younger age and with less kidney involvement benefited the most from therapy. Patients who initiated treatment at older ages and/or had advanced renal disease experienced disease progression. Published by the BMJ Publishing Group Limited.

Background and Aims Cardiovascular disease (CVD) is among the leading causes of morbidity and mortality worldwide. Traditional risk factors predict 75-80% of an individual's risk of incident CVD. However, the role of early life experiences in future disease risk is gaining attention. The Barker hypothesis proposes fetal origins of adult disease, with consistent evidence demonstrating the deleterious consequences of birth weight outside the normal range. In this study, we investigate the role of birth weight in CVD risk prediction. Methods and Results The Women's Health Initiative (WHI) represents a large national cohort of post-menopausal women with 63 815 participants included in this analysis. Univariable proportional hazards regression analyses evaluated the association of 4 self-reported birth weight categories against 3 CVD outcome definitions, which included indicators of coronary heart disease, ischemic stroke, coronary revascularization, carotid artery disease and peripheral arterial disease. The role of birth weight was also evaluated for prediction of CVD events in the presence of traditional risk factors using 3 existing CVD risk prediction equations: one body mass index (BMI)-based and two laboratory-based models. Low birth weight (LBW) (< 6 lbs.) was significantly associated with all CVD outcome definitions in univariable analyses (HR=1.086, p=0.009). LBW was a significant covariate in the BMI-based model (HR=1.128, p<0.0001) but not in the lipid-based models. Conclusion LBW (<6 lbs.) is independently associated with CVD outcomes in the WHI cohort. This finding supports the role of the prenatal and postnatal environment in contributing to the development of adult chronic disease. PMID:26708645

Symptom Management of the Patient with CKD: The Role of Dialysis

Cabrera, Valerie Jorge; Hansson, Joni; Kliger, Alan S.

2017-01-01

As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision–making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

Globally, sexually transmitted disease (STD) is a public health problem. In Nigeria, adolescents form a substantial proportion (22%) of the population and are particularly prone to STDs because of the influence of peer pressure and urge to experiment sexual activity. The study examined the knowledge and attitude of adolescents towards the prevention of sexually transmitted diseases. The survey study was descriptive cross- sectional and carried out among consenting secondary school students aged 10-24 years completing a self- administered questionnaire on knowledge and attitude in relation to sexually transmitted diseases in Ikeji- Arakeji, Oriade Local government, Osun State, Nigeria. The proportionate sampling technique was used to recruit 341 participants into the study. Data were analyzed using descriptive and inferential statistics. Male-Female distributions were 46.3% and 53.7% respectively. Mean age at first sex (sex initiation) was 16.8 years (approximately 17years) and about 97% of the respondents knew about STDs. The media/ magazine was the major source of information about STDs, accounting for more than half (57%) of the responses on sources of STD information followed closely from that from friends with 31%. Parent's source of information was about 11%. Knowledge of STDs centred mainly on HIV/AIDS with 83% and there was a poor knowledge (78%) of its symptoms. About 40% of all respondents had initiated sex at the time of the study and 46% of the adolescents, as against 54%, thought it was bad to initiate sex before marriage. There was a significant association between perception about initiating sex before marriage and ever having sex using bivariate analysis x(2)=268.4, P<0.001). Also, there was a significant difference between the different groups (sources of information) in influencing sex initiation (F=318.47 and P=0.000). Post-hoc analysis showed that each of the different groups (sources of information) was distinct. Adolescents' knowledge of STDs generally limited to HIV/AIDS and perception about sex significantly influenced the decision to initiate sex. There is, therefore, a serious need to implement sexual education and other sexual and reproductive health interventions early for adolescents in Nigeria.

From SARS to strategic actions reframing systems.

The developed world responds to new and re-emerging diseases through the discovery of medications. Disease can be transmitted around the world in a day, but the development of medications does not occur at this rate. The world has one environment and the focus in health care must be on identifying factors in this environment that coalesce to produce disease. The aim of this paper is to introduce the integrative model of environmental health and explore its potential to illuminate the Toronto SARS experience. SARS affected people on three continents in a matter of days. Response to this new disease varied from one area to another and was dependent upon the level of integration of health services and communication across services. The present focus of the health care system is on treating the results of disease rather than the causative factors. Reacting to a new disease had grave social and economic consequences. The time for a new global environmental approach to health is now. The Toronto SARS experience was examined using the integrative model of environmental health and the upstream perspective as exemplars to interrupt the traditional approach to disease. All health care providers share the responsibility to learn about and to understand how our environment creates disease. This knowledge comes through research on topics such as; chemicals, pesticides, soil erosion, killing of forests, contamination of water, destabilization of climate, and social disruption from wars. Health care systems in the developed world continue to focus on the treatment of disease. A global ecological initiative for an integrated disease prevention system must be negotiated among nations.

To explore what it means for patients to live with chronic obstructive pulmonary disease (COPD) as an incurable and constantly progressing disease. Qualitative longitudinal study using narrative and semistructured interviews. This paper presents findings of the initial interviews. Analysis using grounded theory. Lung care clinics and community care in Lower Saxony, Germany. 17 patients with advanced-stage COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) III/IV). Analysis shows that these patients have difficulties accepting their life situation and feel at the mercy of the disease, which could be identified as a core-experienced phenomenon. Over a long period of time, patients have only a vague feeling of being ill, caused by uncertain knowledge, slow progress and doubtful attribution of clinical symptoms of the disease (causal conditions). As an action strategy, patients try to maintain daily routines for as long as possible after diagnosis. Both effective standard and rescue medication, which helps to reduce breathlessness and other symptoms, and the feeling of being faced with one's own responsibility (intervening conditions) support this strategy, whereby patients' own responsibility is too painful to acknowledge. As a consequence, patients try to deny the threat to life for a long period of time. Frequently, they need to experience facing their own limits, often in the form of an acute crisis, to realise their health situation. The experience of the illness is contextualised by a continuous increase in limited mobility and social isolation. In order to help patients to improve disease awareness, to accept their life situation and to improve their reduced quality of life, patients may benefit from the early integration of palliative care (PC), considering its multiprofessional patient-centred and team-centred approach. Psychological support and volunteer work, which are relevant aspects of PC, should be appropriate to address psychosocial needs. More research is needed to evaluate how patients could benefit from early PC. Published by the BMJ Publishing Group Limited.

Several systemic diseases, including granulomatous and infectious processes, tumors, bone disorders, collagen-vascular and other autoimmune diseases may involve the middle ear and temporal bone. These diseases are difficult to diagnose when symptoms mimic acute otomastoiditis. The present report describes our experience with three such cases initially misdiagnosed. Their predominating symptoms were otological with mastoiditis, hearing loss, and subsequently facial nerve palsy. The cases were considered an emergency and the patients underwent tympanomastoidectomy, under the suspicion of otitis media with cholesteatoma, in order to remove a possible abscess and to decompress the facial nerve. The common features were the presence of severe granulation tissue filling the mastoid cavity and middle ear during surgery, without cholesteatoma. The definitive diagnoses was made by means of biopsy of the granulation tissue from the middle ear, revealing granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis) in one case, middle ear tuberculosis and diffuse large B-cell lymphoma respectively. After specific associated therapy facial nerve functions improved, and atypical inflammatory states of the ear resolved. As a group, systemic diseases of the middle ear and temporal bone are uncommon, but aggressive lesions. After analyzing these cases and reviewing the literature, we would like to stress upon the importance of microscopic examination of the affected tissue, required for an accurate diagnosis and effective treatment.

Acropora cervicornis is the most widely used coral species for reef restoration in the greater Caribbean. However, outplanting methodologies (e.g., colony density, size, host genotype, and attachment technique) vary greatly, and to date have not been evaluated for optimality across multiple sites. Two experiments were completed during this study, the first evaluated the effects of attachment technique, colony size, and genotype by outplanting 405 A. cervicornis colonies, from ten genotypes, four size classes, and three attachment techniques (epoxy, nail and cable tie, or puck) across three sites. Colony survival, health condition, tissue productivity, and growth were assessed across one year for this experiment. The second experiment assessed the effect of colony density by outplanting colonies in plots of one, four, or 25 corals per 4 m2 across four separate sites. Plot survival and condition were evaluated across two years for this experiment in order to better capture the effect of increasing cover. Colonies attached with a nail and cable tie resulted in the highest survival regardless of colony size. Small corals had the lowest survival, but the greatest productivity. The majority of colony loss was attributed to missing colonies and was highest for pucks and small epoxied colonies. Disease and predation were observed at all sites, but did not affect all genotypes, however due to the overall low prevalence of either condition there were no significant differences found in any comparison. Low density plots had significantly higher survival and significantly lower prevalence of disease, predation, and missing colonies than high density plots. These results indicate that to increase initial outplant success, colonies of many genotypes should be outplanted to multiple sites using a nail and cable tie, in low densities, and with colonies over 15 cm total linear extension.

HSCT provides the opportunity to replace a damaged tissue. It is the most important treatment for high risk hematologic malignant and non malignant disorders. An important challenge in the identification of matched donors/patients is the HLA diversity. The Mexican Bone Marrow Registry (DONORMO) has nowadays > 5000 donors. The prevalent alleles are Amerindian, Mediterranean (Semitic and Spanish genes) and African. In theory, it is possible to find 11% of 6/6 A-B-DR low resolution matches for 70% of patients with Mexican ancestry. We contributed with 39 unrelated, cord blood and autologous HSCT for patients with malignant, genetic and autoimmune disorders. Overall disease survival was 50% (2-7 years) depending on the initial diagnosis, conditioning, disease evolution or other factors. Clinical studies using autologous and unrelated HSC are performed on patients with refractory autoimmune diseases producing mixed results: mainly, T1D, RA, MS, SLE. Improvement has been observed in skin damage and quality of life in SLE and systemic sclerosis. Disease stabilization in 2/3 of MS patients. However, in RA and T1D, initial benefits have been followed by eventual relapse. With growing clinical experience and protocol improvement, treatment-related mortality is decreasing. Proof efficacy will be achieved by comparing HSCT with standard therapy in autoimmunity.

Treatment of neuro-ophthalmic sarcoidosis.

Frohman, Larry P

2015-03-01

Because of the rarity of neuro-ophthalmic sarcoidosis, there are no therapeutic guidelines based on evidence-based medicine for this disorder. Review of literature combined with personal experience. Corticosteroids are the preferred initial therapy for neuro-ophthalmic sarcoidosis. If patients cannot tolerate the requisite dose of corticosteroid needed to control their disease, or if corticosteroids fail to adequately control the disease process, the choices of a second agent are based on the consideration of rapidity of clinical response and the safety profile. Although methotrexate and mycophenolate mofetil are the medications that are often selected after corticosteroid failure, more rapidly acting agents that have been used are infliximab and intravenous cyclophosphamide.

Comorbidity in Atopic Dermatitis.

Simpson, Eric L

2012-03-01

The negative impact of atopic dermatitis (AD) often extends beyond the skin. Children with AD experience increased rates of infectious, mental health, and allergic diseases compared to their non-atopic peers. The mechanisms underlying these associations remain elusive. New insights from genetic and epidermal research pinpoint the skin barrier as a primary initiator of AD. Epicutaneous sensitization represents an intriguing new model which links a disrupted skin barrier to the later development of IgE-mediated diseases in patients with AD. Recent epidemiological studies have identified new comorbidities linked to AD as well, including several mental health disorders and obesity. This manuscript reviews the recent literature regarding both classic and newly described AD comorbidities.

Use of optical tweezers to probe epithelial mechanosensation

NASA Astrophysics Data System (ADS)

Resnick, Andrew

2010-01-01

Cellular mechanosensation mechanisms have been implicated in a variety of disease states. Specifically in renal tubules, the primary cilium and associated mechanosensitive ion channels are hypothesized to play a role in water and salt homeostasis, with relevant disease states including polycystic kidney disease and hypertension. Previous experiments investigating ciliary-mediated cellular mechanosensation have used either fluid flow chambers or micropipetting to elicit a biological response. The interpretation of these experiments in terms of the ``ciliary hypothesis'' has been difficult due the spatially distributed nature of the mechanical disturbance-several competing hypotheses regarding possible roles of primary cilium, glycocalyx, microvilli, cell junctions, and actin cytoskeleton exist. I report initial data using optical tweezers to manipulate individual primary cilia in an attempt to elicit a mechanotransduction response-specifically, the release of intracellular calcium. The advantage of using laser tweezers over previous work is that the applied disturbance is highly localized. I find that stimulation of a primary cilium elicits a response, while stimulation of the apical surface membrane does not. These results lend support to the hypothesis that the primary cilium mediates transduction of mechanical strain into a biochemical response in renal epithelia.

CLN2 disease (neuronal ceroid lipofuscinosis type 2) is a rare, autosomal recessive, pediatric-onset, rapidly progressive neurodegenerative lysosomal storage disorder caused by tripeptidyl peptidase 1 (TPP1) enzyme deficiency, and is characterized by language delay, seizures, rapid cognitive and motor decline, blindness, and early death. No management guidelines exist and there is a paucity of published disease-specific evidence to inform clinical practice, which currently draws upon experience from the field of childhood neurodisability. Twenty-four disease experts were surveyed on CLN2 disease management and a subset met to discuss current practice. Management goals and strategies are consistent among experts globally and are guided by the principles of pediatric palliative care. Goals and interventions evolve as the disease progresses, with a shift in focus from maintenance of function early in the disease to maintenance of quality of life. A multidisciplinary approach is critical for optimal patient care. This work represents an initial step toward the development of consensus-based management guidelines for CLN2 disease.

2018-06-11

Purpose The purpose of this paper is to understand how staff at various levels perceive and understand hospital accreditation generally and in relation to quality improvement (QI) specifically. Design/methodology/approach In a newly accredited Danish hospital, the authors conducted semi-structured interviews to capture broad ranging experiences. Medical doctors, nurses, a quality coordinator and a quality department employee participated. Interviews were audio recorded and subjected to framework analysis. Findings Staff reported that The Danish Healthcare Quality Programme affected management priorities: office time and working on documentation, which reduced time with patients and on improvement activities. Organisational structures were improved during preparation for accreditation. Staff perceived that the hospital was better prepared for new QI initiatives after accreditation; staff found disease specific requirements unnecessary. Other areas benefited from accreditation. Interviewees expected that organisational changes, owing to accreditation, would be sustained and that the QI focus would continue. Practical implications Accreditation is a critical and complete hospital review, including areas that often are neglected. Accreditation dominates hospital agendas during preparation and surveyor visits, potentially reducing patient care and other QI initiatives. Improvements are less likely to occur in areas that other QI initiatives addressed. Yet, accreditation creates organisational foundations for future QI initiatives. Originality/value The authors study contributes new insights into how hospital staff at different organisational levels perceive and understand accreditation.

In Europe, Spain has the highest number of people with Chagas disease (CD). Bolivian migrants account for 81% of the reported cases. One of the priorities in controlling the disease is prevention of mother-to-child transmission. Despite under-diagnosis in Spain being estimated at 90%, there are currently few studies that explore the social and cultural dimensions of this disease. The aim of this study was to explore the knowledge and experiences of Bolivian women with CD, in order to generate a useful understanding for the design and implementation of public health initiatives. Qualitative study based on semi-structured interviews, triangular groups, and field notes. Fourteen Bolivian women with CD living in Madrid. The participants were aware that the disease was transmitted through the vector, that it could be asymptomatic, and that it could also be associated with sudden death by heart failure. They opined that the treatment as such could not cure the disease but only slow it down. There was a sense of indifference along with a lack of understanding of the risk of contracting the disease. Participants who presented with symptoms, or those with relatives suffering from the disease, were concerned about fatalities, cardiac problems, and possible vertical transmission. There was also a fear of being rejected by others. The disease was described as something that affected a large number of people but only showed up in a few cases and that too after many years. There was a widespread assumption that it was better not to know because doing so, allows the disease to take hold. Disease risk perception was very low in Bolivian women living in Madrid. This factor, together with the fear of being screened, may be contributing to the current rate of under-diagnosis.

Neurodegenerative disorders such as Huntington's disease are hallmarked by neuronal intracellular inclusion body formation. Whether proteasomes are irreversibly recruited into inclusion bodies in these protein misfolding disorders is a controversial subject. In addition, it has been proposed that the proteasomes may become clogged by the aggregated protein fragments, leading to impairment of the ubiquitin-proteasome system. Here, we show by fluorescence pulse-chase experiments in living cells that proteasomes are dynamically and reversibly recruited into inclusion bodies. As these recruited proteasomes remain catalytically active and accessible to substrates, our results challenge the concept of proteasome sequestration and impairment in Huntington's disease, and support the reported absence of proteasome impairment in mouse models of Huntington's disease.

The variety of factors that contributed to the initial undetected spread of Ebola virus disease in West Africa during 2013–2016 and the difficulty controlling the outbreak once the etiology was identified highlight priorities for disease prevention, detection, and response. These factors include occurrence in a region recovering from civil instability and lacking experience with Ebola response; inadequate surveillance, recognition of suspected cases, and Ebola diagnosis; mobile populations and extensive urban transmission; and the community’s insufficient general understanding about the disease. The magnitude of the outbreak was not attributable to a substantial change of the virus. Continued efforts during the outbreak and in preparation for future outbreak response should involve identifying the reservoir, improving in-country detection and response capacity, conducting survivor studies and supporting survivors, engaging in culturally appropriate public education and risk communication, building productive interagency relationships, and continuing support for basic research.

The ubiquitous computing, or ubicomp, is a promising technology to help chronic diseases patients managing activities, offering support to them anytime, anywhere. Hence, ubicomp can aid community and health organizations to continuously communicate with patients and to offer useful resources for their self-management activities. Communication is prioritized in works of ubiquitous health for noncommunicable diseases care, but the management of resources is not commonly employed. We propose the UDuctor, a model for ubiquitous care of noncommunicable diseases. UDuctor focuses the resources offering, without losing self-management and communication supports. We implemented a system and applied it in two practical experiments. First, ten chronic patients tried the system and filled out a questionnaire based on the technology acceptance model. After this initial evaluation, an alpha test was done. The system was used daily for one month and a half by a chronic patient. The results were encouraging and show potential for implementing UDuctor in real-life situations.

The clinical profile and outcome of neuroblastoma in 103 children, older than one-year is presented. 74 had Stage IV, 27 Stage III and one patient each had Stage I or II disease. Treatment included chemotherapy followed by surgical resection/debulking. Radiotherapy was administered to those with residual tumor. Chemotherapy consisted of OPEC (vincristine, cyclophosphamide, cisplatin and etoposide). The caretakers of 54 (52.4%) children either did not opt for or defaulted therapy, whilst 3 patients died before chemotherapy could be initiated. Of the remaining 46 patients, the tumor progressed during therapy in 19 (41.3%). Relapse of disease was documented in 22 (47.8%) cases. Merely 4 (8.7%) children are disease free for a period of 16.5+/-6.7 months. Majority of children presented with advanced disease and the outcome was dismal with conventional non-myloablative chemotherapy.

Recent evidence supports the prognostic significance of frailty for functional decline and poor health outcomes in patients with chronic kidney disease. Yet, despite the development of clinical tools to screen for frailty, little is known about the experiential impact of screening for frailty in this setting. The Frailty Assessment for Care Planning Tool (FACT) evaluates frailty across 4 domains: mobility, function, social circumstances, and cognition. The purpose of this qualitative study was as follows: 1) explore the nurse experience of screening for frailty using the FACT tool in a specialized outpatient renal clinic; 2) determine how, if at all, provider perceptions of frailty changed after implementation of the frailty screening tool; and 3) determine the perceived factors that influence uptake and administration of the FACT screening tool in a specialized clinical setting. A semi-structured interview of 5 nurses from the Nova Scotia Health Authority, Central Zone Renal Clinic was conducted. A grounded theory approach was used to generate thematic categories and analysis models. Four primary themes emerged in the data analysis: "we were skeptical", "we made it work", "we learned how", and "we understand". As the renal nurses gained a sense of confidence in their ability to implement the FACT tool, initial barriers to implementation were attenuated. Implementation factors - such as realistic goals, clear guidelines, and ongoing training - were important factors for successful uptake of the frailty screening initiative. Nurse participants reported an overall positive experience using the FACT method to screen for frailty and indicated that their understanding of the multiple dimensions and subtleties of "frailty" were enhanced. Future nurse-led FACT screening initiatives should incorporate those factors identified as being integral to program success: realistic goals, clear guidelines, and ongoing training. Adopting the evaluation of frailty as a priority within clinical departments will encourage sustainability.

The purpose of this review is to provide (1) a synopsis on relations of mindfulness with cardiovascular disease (CVD) and major CVD risk factors, and (2) an initial consensus-based overview of mechanisms and theoretical framework by which mindfulness might influence CVD. Initial evidence, often of limited methodological quality, suggests possible impacts of mindfulness on CVD risk factors including physical activity, smoking, diet, obesity, blood pressure, and diabetes regulation. Plausible mechanisms include (1) improved attention control (e.g., ability to hold attention on experiences related to CVD risk, such as smoking, diet, physical activity, and medication adherence), (2) emotion regulation (e.g., improved stress response, self-efficacy, and skills to manage craving for cigarettes, palatable foods, and sedentary activities), and (3) self-awareness (e.g., self-referential processing and awareness of physical sensations due to CVD risk factors). Understanding mechanisms and theoretical framework should improve etiologic knowledge, providing customized mindfulness intervention targets that could enable greater mindfulness intervention efficacy.

With the advent of the epidemiological transition, chronic non-communicable diseases (CNCDs) have emerged as the leading cause of death globally. In this paper we present an overview of the burden of CNCDs in the Caribbean region and use Jamaica as a case-study to review the impact of policy initiatives and interventions implemented in response to the CNCD epidemic. The findings show that while Jamaica has implemented several policy initiatives aimed at stemming the tide of the CNCD epidemic, a comparison of data from two national health and lifestyle surveys conducted in Jamaica in 2000/01 and 2007/08 revealed that there was an increase in the prevalence of intermediate CNCD risk factors such as hypertension and obesity. We therefore present recommended strategies which we believe will enhance the current CNCD response and thus reduce, or at least stem, the current epidemic of CNCDs.

Patient-support organizations can facilitate a significant change in the way rare disorders are approached. Besides connecting families with each other and directing patients to experienced medical specialists, these groups, by collaborating with government initiatives like COST, can effect the direction and funding of rare disease research. By concentrating the rare disease patient population and funneling them to specific centers of excellence, these organizations help build specialists' experience and their study populations. It requires a basic spirit of collaboration, driven parent leaders, a well-organized support platform, sources of funding, supportive clinical and research professionals and finally an effective method of collecting and disseminating information. Silver-Russell Syndrome is an excellent example of a rare disorder that has become better recognized, understood and treated because patient-support organizations, using the internet as a critical tool, have worked together with clinical care/research specialists and public funding agencies to build collaboration.

Although definitions of mass gatherings (MG) vary greatly, they consist of large numbers of people attending an event at a specific site for a finite time. Examples of MGs include World Youth Day, the summer and winter Olympics, rock concerts, and political rallies. Some of the largest MGs are spiritual in nature. Among all MGs, the public health issues, associated with the Hajj (an annual pilgrimage to Mecca, Saudi Arabia) is clearly the best reported-probably because of its international or even intercontinental implications in terms of the spread of infectious disease. Hajj routinely attracts 2·5 million Muslims for worship. WHO's global health initiatives have converged with Saudi Arabia's efforts to ensure the wellbeing of pilgrims, contain infectious diseases, and reinforce global health security through the management of the Hajj. Both initiatives emphasise the importance of MG health policies guided by sound evidence and based on experience and the timeliness of calls for a new academic science-based specialty of MG medicine.

Fabry disease, an X-linked lysosomal storage disorder, causes intracellular accumulation of glycosphingolipids leading to progressive renal, cardiovascular, and cerebrovascular disease, and premature death. This longitudinal Fabry Registry study analyzed data from patients with Fabry disease to determine the incidence and type of severe clinical events following initiation of enzyme replacement therapy (ERT) with agalsidase beta, as well as risk factors associated with occurrence of these events. Severe events assessed included chronic dialysis, renal transplantation, cardiac events, stroke, and death. The analyses included 969 male and 442 female Fabry patients. The mean age at first agalsidase beta infusion was 35 and 44, and median treatment follow-up 4.3years and 3.2years, respectively. Among males, cardiac events were the most common on-ERT events, followed by renal, stroke, and non-cardiac death. Among females, cardiac events were also most common followed by stroke and renal events. Patients with on-ERT events had significantly more advanced cardiac and renal disease at baseline as compared with patients without on-ERT events. Severe events were also associated with older age at ERT initiation (males and females), a history of pre-ERT events (females; approaching statistical significance in males), and a higher urinary protein/creatinine ratio (females). Approximately 65% of patients with pre-ERT events did not experience subsequent on-ERT events. Of patients without pre-ERT events, most (84% of males, 92% of females) remained event-free. Patients with on-ERT severe events had more advanced Fabry organ involvement at baseline than those without such events and patients who initiated ERT at a younger age had less residual risk of on-ERT events. The observed patterns of residual risk may aid clinicians in multidisciplinary monitoring of male and female patients with Fabry disease receiving ERT, and in determining the need for administration of adjunctive therapies.

Initial lessons from public-private partnerships in drug and vaccine development.

PubMed Central

Wheeler, C.; Berkley, S.

2001-01-01

In recent years, venture capital approaches have delivered impressive results in identifying and funding promising health discoveries and bringing them to market. This success has inspired public sector experiments with "social venture capital" approaches to address the dearth of affordable treatment and prevention for diseases of the developing world. Employing the same focus on well-defined and measurable objectives, and the same type of connections to pool and deploy resources as their for-profit counterparts, social venture capitalists seek to use the tools and incentives of capitalism to solve one of its biggest failures: the lack of drugs and vaccines for diseases endemic to low-income populations. As part of a larger trend of partnerships emerging in health product donation and distribution, public-private partnerships for pharmaceutical development have led research and development (R&D) efforts to generate more accessible and efficacious products for diseases such as malaria, tuberculosis, and AIDS. In this article, three R&D-focused partnerships are explored: the International AIDS Vaccine Initiative; the Medicines for Malaria Venture; and the newly formed Global Alliance for TB Drug Development. The article highlights key elements essential to the success of these ventures. PMID:11545329

Symptom Management of the Patient with CKD: The Role of Dialysis.

2017-04-03

As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision-making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

The discussion adopts a citizen-centred perspective to consider how the different e-portal systems support, protect and structure citizen interactions with their own health data in three key areas: Security, privacy and data protection; User support; and Citizen adoption and use. The paper highlights the impact of opt-in/opt-out approaches on citizen access and the lack of a structured approach to addressing differences in citizen health and e-health literacy. This research also confirms while current data provides detail on the availability and use of personal health data by citizens, questions still remain over the ultimate impact on patient outcomes of these initiatives. It is anticipated the insights generated from the three countries experiences, supporting citizen access to their health data will be useful to improve these initiatives and guide other countries aspiring to support similar initiatives.

2014-12-01

Achalasia is a progressive oesophageal motility disorder of unstudied aetiology involving the smooth muscle layer of the oesophagus. Insufficient knowledge of the pathogenesis of achalasia and the lack of clear treatment approaches has led to an increase of advanced disease forms. Common clinical manifestations of the disease are: incomplete LES relaxation, non-specific initial manifestations and as a result late medical seeking. Occurrence of achalasia cardiae is significantly low, therefore it is important to analyse the available clinical data. The article presents an experience of treatment of 30 patients over the last 16 years of observation. The average age of patients was 50, 5 years; insignificant male predominance is noted. III or IV disease state was diagnosed in 86.7% of patients; this diagnosis was confirmed by esophagogastroduodenoscopy. In the group of 24 patients who underwent attempted endoscopic dilatation of the cardiae, most of the included patients with stage II and III disease. Immediate good and satisfactory results of endoscopic treatment were obtained in 20 patients (83.3%), in 4 cases (16.7%) developed recurrent disease.

Making sense of OMICS data in population-based environmental health studies.

PubMed

Kyrtopoulos, Soterios A

2013-08-01

Although experience from the application of OMICS technologies in population-based environmental health studies is still relatively limited, the accumulated evidence shows that it can allow the identification of features (genes, proteins, and metabolites), or sets of such features, which are targeted by particular exposures or correlate with disease risk. Such features or profiles can therefore serve as biomarkers of exposure or disease risk. Blood-based OMIC profiles appear to reflect to some extent events occurring in target tissues and are associated with toxicity or disease and therefore have the potential to facilitate the elucidation of exposure-disease relationships. Further progress in this direction requires better understanding of the significance of exposure-induced network perturbations for disease initiation and progression and the development of a framework that combines agnostic searches with the utilization of prior knowledge, taking account of particular elements which characterize the structure and evolution of complex systems and brings in principles of systems biology.

Bridbord, Kenneth; Hanson, David

2009-01-01

Objective This article describes the personal experience and perspective of the authors, who had primary responsibility for drafting the initial health-based regulation limiting lead content of gasoline during the early 1970s while employed by the U.S. Environmental Protection Agency (EPA). Data source Information used by the U.S. EPA in developing the initial health-based regulation limiting lead content of gasoline in December 1973 and studies documenting the impact of that and subsequent actions. Data extraction Among the lessons learned from this experience is the importance of having input from independent scientists to the regulatory decision-making process. This also demonstrates the critical role of independent peer-reviewed research, such as that supported by the National Institutes of Health, as well as research conducted by scientists from the Centers for Disease Control and Prevention, in delineating the consequences of lead exposure in the population. Data synthesis Removal of lead from gasoline in the United States has been described as one of the great public health achievements of the 20th century, but it almost did not happen. The experience of the authors in developing this regulation may be helpful to others involved in developing health-based regulatory policy in the future. Conclusion The initial U.S. EPA health-based regulation to remove lead from gasoline is clearly an example where science successfully affected public policy. The leadership of the U.S. EPA at that time deserves much credit for establishing an atmosphere in which this was possible. PMID:19672397

To identify innovative strategies for improved care and self-care of patients with chronic diseases (CD) in Latin America and to explore interest in creating a Latin American network of professionals in this field. A descriptive study based on a survey of key experts with recognized national or regional leadership in CD patient care. The 25-question questionnaire sought information on their experiences with care and self-care initiatives for CD patients, descriptions of successful initiatives, the perceived ability of countries to innovate in this area, their interest in participating in a network of Latin American professionals in this field, and more. Content analysis was performed to develop recommendations for the Region. Responses were obtained from 17 (37.8%) of the 45 experts approached; 82.4% confirmed their knowledge of of involvement with an innovative initiative related to the subject. Initial development does exist in each of the three innovative strategy types: peer care, informal caregivers, and telenursing, the latter being the least explored. There is real interest in forming a Latin American network that focuses on development of innovative self-care strategies for CD patients. Support for a joint network is promising. Priorities are building skills in this area and developing innovative proposals for improved CD patient care in the Region. Innovative measures should be complementary and adapted to the specific context of each scenario.

Disturbance Driven Colony Fragmentation as a Driver of a Coral Disease Outbreak

Brandt, Marilyn E.; Smith, Tyler B.; Correa, Adrienne M. S.; Vega-Thurber, Rebecca

2013-01-01

In September of 2010, Brewer's Bay reef, located in St. Thomas (U.S. Virgin Islands), was simultaneously affected by abnormally high temperatures and the passage of a hurricane that resulted in the mass bleaching and fragmentation of its coral community. An outbreak of a rapid tissue loss disease among coral colonies was associated with these two disturbances. Gross lesion signs and lesion progression rates indicated that the disease was most similar to the Caribbean coral disease white plague type 1. Experiments indicated that the disease was transmissible through direct contact between colonies, and five-meter radial transects showed a clustered spatial distribution of disease, with diseased colonies being concentrated within the first meter of other diseased colonies. Disease prevalence and the extent to which colonies were bleached were both significantly higher on unattached colony fragments than on attached colonies, and disease occurred primarily on fragments found in direct contact with sediment. In contrast to other recent studies, disease presence was not related to the extent of bleaching on colonies. The results of this study suggest that colony fragmentation and contact with sediment played primary roles in the initial appearance of disease, but that the disease was capable of spreading among colonies, which suggests secondary transmission is possible through some other, unidentified mechanism.

Reducing the burden of chronic conditions among minorities requires novel approaches to prevent and manage disease. This paper describes the expansion of the Chronic Care Model (CCM) to include a community focus for improving diabetes self-management and reducing health disparities. The literature review assesses the concept of "community" in improving outcomes as viewed by proponents of the CCM for chronic disease. The CCM was then modified and informed by experiences of a major community-based participatory action initiative to improve diabetes outcomes, the Racial and Ethnic Approaches to Community Health (REACH) Charleston and Georgetown Diabetes Coalition. Based on our experiences with community-based and health systems diabetes interventions, we present examples of improvements within both health delivery practice sites and other community systems that are essential for improving diabetes outcomes and reducing disparities. Building on the Centers for Disease Control and Prevention's (CDC) principles of community involvement, our coalition activities provide examples of working with community partners to frame this enhanced ecologically grounded Community CCM (CCCM). The resulting CCCM integrates expanded conceptual frameworks, evidence-based practice, community-based evidence and participatory actions, and highlights the possibilities and challenges for improving chronic disease outcomes and reducing disparities via community programs that foster individual, systems, community, and policy change.

State Synergies and Disease Surveillance: Creating an Electronic Health Data Communication Model for Cancer Reporting and Comparative Effectiveness Research in Kentucky

PubMed Central

Reams, Christopher; Powell, Mallory; Edwards, Rob

2014-01-01

Purpose: This case study describes the collaboration between a state public health department, a major research university, and a health extension service funded as part of the Health Information Technology for Economic and Clinical Health (HITECH) Act to establish an interoperable health information system for disease surveillance through electronic reporting of systemic therapy data from numerous oncology practices in Kentucky. The experience of the Kentucky cancer surveillance system can help local and state entities achieve greater effectiveness in designing communication efforts to increase usage of electronic health records (EHRs) and health information exchanges (HIEs), help eligible clinicians meet these new standards in patient care, and conduct disease surveillance in a learning health system. Innovation: We document and assess the statewide efforts of early health information technology (HIT) adopters in Kentucky to facilitate the nation’s first electronic transmission of a clinical document architecture (CDA) from a physician office to a state cancer surveillance registry in November 2012. Successful transmission of the CDA not only represented a landmark for technology innovators, informaticists, and clinicians, but it also set in motion a new communication mechanism by which state and federal agencies can capture and trade vital cancer statistics in a way that is safe, secure, and timely. The corresponding impact this has on cancer surveillance and comparative effective research is immense. With guidance from the Centers for Disease Control and Prevention (CDC), the Kentucky Cancer Registry (KCR), the Kentucky Health Information Exchange (KHIE), and the Kentucky Regional Extension Center (KREC) have moved one step further in transforming the interoperable health environment for improved disease surveillance. Credibility: This case study describes the efforts of established and reputable agencies, including the KCR, the state department of health, state and federal governmental agencies, and a major research university in leveraging existing networks, infrastructure, and federally awarded funding to implement interoperable health information systems for disease surveillance. Project assessment through quasi-qualitative interviews with key stakeholders facilitated evaluation of attitudes and beliefs for continued use of the cancer surveillance model. Conclusion and Discussion: In Kentucky, the cancer reporting initiative leveraged and enhanced a solid foundation for statewide collaboration to achieve better health and improved disease surveillance through a learning health system. Leveraging the Meaningful Use (MU) program as an overarching policy and structural driver is imperative. The cancer reporting initiative in Kentucky suggests that future surveillance and reporting initiatives will require locally adaptable solutions and that there is a need for increased technical assistance in rural settings. Kentucky’s experience also indicates that stakeholders should be diligent in identifying state-level criteria that align with MU for vetting EHR vendors. PMID:25848604

Haemophilus parasuis causes Glässer's disease, a syndrome of polyserositis, meningitis, and arthritis in swine. Previous studies with H. parasuis have revealed virulence disparity among isolates and inconsistent heterologous protection. In this study, virulence, direct transmission, and heterologous protection of 4 isolates of H. parasuis (SW114, 12939, MN-H, and 29755) were evaluated using a highly susceptible pig model. In an initial experiment, isolates 12939, MN-H, and 29755 caused Glässer's disease, while strain SW114 failed to cause any clinical signs of disease. One pig from each group challenged with MN-H or 29755 failed to develop clinical disease but was able to transmit H. parasuis to noninfected pigs, which subsequently developed Glässer's disease. Pigs colonized with SW114, 29755, or MN-H that were free of clinical disease were protected from a subsequent challenge with isolate 12939. In a following experiment, pigs vaccinated with strain SW114 given as either a bacterin intramuscularly or a live intranasal vaccine were protected from subsequent challenge with isolate 12939; however, some pigs given live SW114 developed arthritis. Overall these studies demonstrated that pigs infected with virulent isolates of H. parasuis can remain healthy and serve as reservoirs for transmission to naive pigs and that heterologous protection among H. parasuis isolates is possible. In addition, further attenuation of strain SW114 is necessary if it is to be used as a live vaccine.

Epigenetic Modifications of Major Depressive Disorder

Major depressive disorder (MDD) is a chronic disease whose neurological basis and pathophysiology remain poorly understood. Initially, it was proposed that genetic variations were responsible for the development of this disease. Nevertheless, several studies within the last decade have provided evidence suggesting that environmental factors play an important role in MDD pathophysiology. Alterations in epigenetics mechanism, such as DNA methylation, histone modification and microRNA expression could favor MDD advance in response to stressful experiences and environmental factors. The aim of this review is to describe genetic alterations, and particularly altered epigenetic mechanisms, that could be determinants for MDD progress, and how these alterations may arise as useful screening, diagnosis and treatment monitoring biomarkers of depressive disorders.

In Brazil, as in the rest of the world, the prevalence of chronic kidney disease (CKD) is increasing. In order to alert the population, health professionals and authorities to this risk, in 2003, the Brazilian Society of Nephrology launched a CKD prevention campaign called 'Previna-se'. In addition, since its onset, Brazil has participated in the World Kidney Day efforts and has developed several prevention strategies. Here, we summarize the main strategies adopted in this campaign (population screening, events and meetings, distribution of educational materials, routine report of estimated glomerular filtration rate) and our initial results, sharing practical experience that could be useful in other developing countries.

Careaga-Reyna, Guillermo; Lázaro-Castillo, José Luis; Lezama-Urtecho, Carlos Alberto; Macías-Miranda, Enriqueta; Dosta-Herrera, Juan José; Galván Díaz, José

Aortic stenosis is a frequent disease in the elderly, and is associated with other systemic pathologies that may contraindicate the surgical procedure. Another option for these patients is percutaneous aortic valve implantation, which is less invasive. We present our initial experience with this procedure. Patients with aortic stenosis were included once selection criteria were accomplished. Under general anaesthesia and echocardiographic and fluosocopic control, a transcatheter aortic valve was implanted following s valvuloplasty. Once concluded the procedure, angiographic and pressure control was realized in order to confirm the valve function. Between November 2014 and May 2015, 6 patients were treated (4 males and 2 females), with a mean age of 78.83±5.66 years-old. The preoperative transvalvular gradient was 90.16±28.53mmHg and posterior to valve implant was 3.33±2.92mmHg (P<.05). Two patients had concomitant coronary artery disease which had been treated previously. One patient presented with acute right coronary artery occlusion which was immediately treated. However due to previous renal failure, postoperative sepsis and respiratory failure, the patient died one month later. It was concluded that our preliminary results showed that in selected patients percutaneous aortic valve implantation is a safe procedure with clinical improvement for treated patients.

Aim. In this study we report our experience with microhematuria and its relation with bladder tumors in Iranian women. Materials and Methods. Overall 249 women were evaluated. Microscopic hematuria was defined as three or more red blood cells per high-power field on at least two different occasions. Patients with a history of gross hematuria or coagulation disorders, having organic diseases, urinary stones, urinary tract infections, nephrological diseases, and local lesions such as urethral caruncle were excluded from the study population. Final diagnosis of malignant tumors was done with cystoscopy and biopsy specimen pathological assessment in all cases. Results. Age for the study population was 49.7 ± 11.8 years. 95 (38%) of patients were identified during routine check up and presenting symptoms in other patients were frequency, dysuria, stress urge incontinence, urge incontinence, feeling of incomplete urine emptying, and flunk pain, respectively. Finally, 7 (2.8%) of study subjects were confirmed as having bladder tumors. One of tumor cases was diagnosed 24 months after initial assessments. Patients with bladder tumor were significantly older; more frequently had diverticulum in their bladder wall (P < .05). Conclusion. Female microscopic hematuria is relevant and deserves evaluations, especially in elderly patients. Patients whose reason for microhematuria would not be diagnosed at the initial evaluations should be followed. PMID:19639044

It has been suggested that initiatives to eradicate specific communicable diseases need to be informed by eradication investment cases to assess the feasibility, costs, and consequences of eradication compared with elimination or control. A methodological challenge of eradication investment cases is how to account for the ethical importance of the benefits, burdens, and distributions thereof that are salient in people’s experiences of the diseases and related interventions but are not assessed in traditional approaches to health and economic evaluation. We have offered a method of ethical analysis grounded in theories of social justice. We have described the method and its philosophical rationale and illustrated its use in application to eradication investment cases for lymphatic filariasis and onchocerciasis, 2 neglected tropical diseases that are candidates for eradication.

Current guidelines for cholesterol treatment emphasize the importance of engaging patients in a risk-benefit discussion prior to initiating statin therapy. Although current risk prediction algorithms are well defined, there is less data on how to communicate with patients about cardiovascular disease risk, benefits of treatment, and possible adverse effects. We propose a four-part model for effective shared decision-making: 1) Assessing patient priorities, perceived risk, and prior experience with cardiovascular risk reduction; 2) Arriving at a recommendation for therapy based on the patient's risk of disease, guideline recommendations, new clinical trial data, and patient preferences; 3) Communicating this recommendation along with risks, benefits, and alternatives to therapy following best practices for discussing numeric risk; and 4) Arriving at a shared decision with the patient with ongoing reassessment as risk factors and patient priorities change.

Redo pullthrough for Hirschsprung disease.

Pullthrough procedures for Hirschsprung diseases typically have favorable results. However, some children experience long-term postoperative complications comprising stooling disorders, such as intermittent enterocolitis, severe stool retention, intestinal obstruction, as well as incontinence. Reoperative Hirschsprung Disease surgery is complex. This begins with the workup after the initial presentation following primary pullthrough, continues with the definitive surgical correction with redo pullthrough, and ends with long-term follow-up of individuals. The decision tree can be varied with each patient. The operating pediatric surgeon must be able to utilize different operations and treatment options available. While lesser procedures may provide relief in a select population, those with residual aganglionosis or transition zone pathology or mechanical problems will likely require a redo pullthrough. Thus, the diagnostic workup, treatment plan, and definitive surgical care should be coordinated, and executed by an experienced, specialized team at a pediatric referral center.

Background The Eating and Cooking Healthy (TEACH) Kitchen was founded at the Medical College of Georgia in 2015 as a nutrition-based intervention to combat the high prevalence of obesity and obesity-related chronic diseases in the area of Augusta, Georgia. Despite the importance of diet in the management of chronic diseases, inadequate nutrition education among patients and healthcare providers presents a barrier. The purpose of TEACH Kitchen is to address this gap. Methods TEACH Kitchen is as a student-led initiative that promotes healthy cooking among medical students and patients with chronic diseases. Healthy nutrition and cooking classes are held during the academic year. Participants spend four weeks on each of four modules: obesity, hypertension, hyperlipidemia, and diabetes mellitus. Data collection, which began in January 2017, is currently on going. TEACH Kitchen has collaborated with Augusta University, Sodexo, and Kohl’s. Results Currently, TEACH Kitchen has enrolled 14 patients and 6 children. Anticipated results include measurements of pre-and post-intervention changes in knowledge, attitudes, beliefs, and competence in nutrition, as well as differences in clinical indicators, including body mass index, blood pressure, lipid profile, and HbA1c. Conclusions TEACH Kitchen is the first medical school-based nutrition/cooking education initiative in Augusta, Georgia. It provides patients and medical students with hands-on healthy nutrition/cooking experience with the goal of decreasing the prevalence and improving the outcome of obesity-related diseases.

1988-12-01

The medical records of 414 patients with metastatic breast carcinoma treated between 1978 and 1986 were reviewed and 44 women were identified as having stage IV disease when the primary breast lesion was detected. Of these 44 women, 25 had metastatic disease limited to the skeleton while 19 had extraosseous lesions only. The clinical features, response to therapy, and survival were analyzed and compared for both groups. The median survival of those patients with bone-only metastases was 52 months as compared with 13 months for those with extraskeletal lesions (p = 0.0025). The response rate to first-line systemic therapy was similar for both groups (47% for bone metastases and 44% for extraosseous metastases). The median duration of response was 14 months (range, 3-55 months) for patients with bone disease and 8 months (range, 4-43 months) for those with extraskeletal lesions. We conclude that patients with metastatic breast cancer confined to the skeleton at initial diagnosis tend to follow an indolent, chronic course with prolonged survival. Therefore the increase in response rate with aggressive chemotherapy should be balanced against its higher morbidity. Further studies are needed to confirm whether the better prognosis of these patients is determined by the anatomical confinement of the disease to the skeleton or merely reflects the influence of other prognostic factors.

Approximately 15-20% of patients with chronic obstructive pulmonary disease (COPD) also display characteristics of asthma. In May 2014, the asthma-COPD overlap syndrome (ACOS) was briefly addressed in the Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy documents. We evaluated how pulmonologists diagnose and treat ACOS and how they assess its control. Pulmonologists from two university healthcare centers, having ≥ 1 year experience, treating patients with asthma, COPD, or ACOS, were invited to participate in focus groups. Two focus groups (1 hour duration) were convened with seven and five participants, respectively. According to pulmonologists from both institutions, ACOS is a new name for an existing syndrome rather than a new disease. It is characterized by incomplete reversible airflow limitations and changes in forced expiratory volume in one second over time. The pulmonologists noted that its diagnosis must be based on clinical characteristics, pulmonary function test results, and clinical intuition. To diagnose ACOS, pulmonologists must rely on their clinical judgment. They also agreed that the treatment of patients with ACOS should target the features of both asthma and COPD. Pulmonologists from both institutions used asthma control criteria to assess ACOS control. A deeper understanding would enable clinicians to establish specific criteria for the diagnosis, treatment, and follow-up of subjects with ACOS.

Structural heart disease is highly prevalent in patients with chronic kidney disease requiring dialysis. More than 80% of patients with end-stage renal disease (ESRD) are reported to have cardiovascular disease. This observation has enormous clinical relevance because the leading causes of death for patients with ESRD are of cardiovascular disease etiology, including heart failure, myocardial infarction, and sudden cardiac death. The 2 systems most commonly used to classify the severity of heart failure are the New York Heart Association (NYHA) functional classification and the American Heart Association (AHA)/American College of Cardiology (ACC) staging system. With rare exceptions, patients with ESRD who do not receive renal replacement therapy (RRT) develop signs and symptoms of heart failure, including dyspnea and edema due to inability of the severely diseased kidneys to excrete sodium and water. Thus, by definition, nearly all patients with ESRD develop a symptomatology consistent with heart failure if fluid removal by RRT is delayed. Neither the AHA/ACC heart failure staging nor the NYHA functional classification system identifies the variable symptomatology that patients with ESRD experience depending upon whether evaluation occurs before or after fluid removal by RRT. Consequently, the incidence, severity, and outcomes of heart failure in patients with ESRD are poorly characterized. The 11th Acute Dialysis Quality Initiative has identified this issue as a critical unmet need for the proper evaluation and treatment of heart failure in patients with ESRD. We propose a classification schema based on patient-reported dyspnea assessed both pre- and post-ultrafiltration, in conjunction with echocardiography.

Faster forgetting contributes to impaired spatial memory in the PDAPP mouse: Deficit in memory retrieval associated with increased sensitivity to interference?

Two experiments were conducted to investigate the possibility of faster forgetting by PDAPP mice (a well-established model of Alzheimer’s disease as reported by Games and colleagues in an earlier paper). Experiment 1, using mice aged 13–16 mo, confirmed the presence of a deficit in a spatial reference memory task in the water maze by hemizygous PDAPP mice relative to littermate controls. However, after overtraining to a criterion of equivalent navigational performance, a series of memory retention tests revealed faster forgetting in the PDAPP group. Very limited retraining was sufficient to reinstate good memory in both groups, indicating that their faster forgetting may be due to retrieval failure rather than trace decay. In Experiment 2, 6-mo-old PDAPP and controls were required to learn each of a series of spatial locations to criterion with their memory assessed 10 min after learning each location. No memory deficit was apparent in the PDAPP mice initially, but a deficit built up through the series of locations suggestive of increased sensitivity to interference. Faster forgetting and increased interference may each reflect a difficulty in accessing memory traces. This interpretation of one aspect of the cognitive deficit in human mutant APP mice has parallels to deficits observed in patients with Alzheimer’s disease, further supporting the validity of transgenic models of the disease.

This article reviews a sample of narratives written since 1950 by people knowingly facing death as a result of cancer and other diseases, in order to compare experiences and show how these relate to wider changes in practice in end of life care. A bibliographic search of libraries, archives, journals and internet sources located English spoken literature, including books, poems, newspapers, journal articles, diaries, and internet postings of writings by people facing terminal disease. Bibliometric and qualitative content analysis explored changing authorship, experiences, purpose in writing, and reported the impact on readers. The initial search located a wide range of published and unpublished narratives, to which inclusion/exclusion criteria were applied, yielding 148 narratives by different authors since 1950. A purposive sub-sample of 63 of these narratives was reviewed. Over the last half century there have been changes in both the volume of available literature and patterns of writing about end of life experience. Therapeutic benefits of writing are reported as a way of making sense of dying combined with a strong sense of purpose in sharing the story. There is a clear awareness of social needs when dying, along with issues of communication with medical staff, symptom control, realities of suffering, and spiritual aspects of dying. Differences are found in the nature and style of writing about cancer in comparison to other illnesses.

Caring For Kids Where They Live: interprofessional collaboration in teaching and learning in school settings.

Across North America, educators are challenged with finding learning opportunities for students in the health professions. Faculty members with a pediatric specialization in nursing recognized that schools were an ideal setting to provide children with care from the health continuum including health promotion, assessment and treatment, and chronic disease management. The faculty of nursing at a Western Canadian University established a unique educational approach by creating an interprofessional pediatric clinical learning experience titled, Caring For Kids Where They Live. This practicum brings together students in the health professions (nurses, dentists, and kinesiologists) and students and their families from three urban schools; one elementary school and two high schools. The primary goals of this partnership were to create an interprofessional clinical learning experience and to promote health and wellness of children and youth. This initiative far exceeded the initial goals.

An increasing spectrum and number of opportunistic fungal pathogens have been reported to cause disease in humans over the past decade. Disseminated phaeohyphomycoses caused by rare dematiaceous molds in immunocompromised patients have a high mortality rate and are increasingly reported in the literature. Early diagnosis of disseminated phaehyphomycosis is critical especially in neutropenic patients but can be hindered by the low sensitivity of fungal blood cultures and low clinical suspicion. Cutaneous manifestations are often the earliest sign of disease and conducting a thorough skin exam in febrile neutropenic patients can lead to more rapid diagnosis and initiation of treatment. PCR amplification and sequencing of mold RNA extracted from paraffin-embedded tissue can be useful for diagnosing rare fungal infections when negative fungal cultures preclude morphologic diagnosis. Effective treatment for disseminated phaehyphomycosis is lacking and there is a need to report experiences with the use of newer antifungals. © 2015 John Wiley & Sons A/S.

The introduction of anti-tumor necrosis factor medications has revolutionized the treatment of psoriasis with achievement of treatment goals (Psoriasis Area and Severity Index score 75, remission) that are not usually met with conventional systemics. Nevertheless, some patients continue to experience persistent disease activity or treatment failure over time. Strategies to optimize treatment outcomes include the use of concomitant methotrexate, which has demonstrated beneficial effects on pharmacokinetics and treatment efficacy in psoriasis and other inflammatory diseases. This is an investigator-initiated, multicenter randomized controlled trial (RCT) designed to compare the combination treatment of adalimumab and methotrexate with adalimumab monotherapy in patients with psoriasis. The primary outcome is adalimumab drug survival at week 49. Other outcomes include improvement in disease severity and quality of life, tolerability, and safety. Moreover, anti-adalimumab antibodies and adalimumab serum concentrations will be measured and correlations between genotypes and clinical outcomes will be assessed. Patient recruitment started in March 2014. Up to now, 36 patients have been randomized. Many more patients have been (pre)screened. A total of 93 patients is desired to meet an adequate sample size. In our experience, the main limitation for recruitment is prior adalimumab therapy and intolerability or toxicity for methotrexate in the past. OPTIMAP is the first RCT to examine combination therapy with adalimumab and methotrexate in a psoriasis population. With data derived from this study we expect to provide valuable clinical data on long-term treatment outcomes. These data will be supported by assessment of the impact of concomitant methotrexate on adalimumab pharmacokinetics. Furthermore, the influence of several single nucleotide polymorphisms on adalimumab response will be analyzed in order to support the development of a more personalized approach for this targeted therapy.

Challenges to global measles eradication: is it all in the timing?

Davis, Robert; Mbabazi, William Baguma

The case for global eradication of measles was first made in 1982. Since then, technical aspects of measles eradication have concluded that measles satisfied all criteria required for eradication. To date, only smallpox, among human diseases, has been eradicated, with polio, the next eradication candidate. In all previous eradication programmes, the pattern of slow implementation and missed deadlines is similar. Lessons from these past eradication programs should inform development of a time-limited measles eradication program. Notably, no measles eradication resolution is likely until member states are satisfied that polio eradication is accomplished. However, there is an impetus for measles eradication from the western hemisphere, where governments continue to pay the high costs of keeping their region measles free until global measles eradication is achieved. While previous vaccine preventable diseases eradications have depended on supplemental immunizations (SIAs), measles eradication will have to build both on SIAs and routine immunization systems strengthening. This article reviews non-technical considerations that could facilitate the delivery of a time-limited measles eradication initiative. The issues discussed are categorized as a) specificities of measles disease; b) specifics of measles vaccine/vaccination; c) special considerations for endemic countries and d) organization of international partnerships. The disease and vaccine specific issues are not insurmountable. The introduction of routine measles second dose, in the context of EPI systems strengthening, is paramount to endemic developing countries. In the international partnerships, it should be noted that i) Measles eradication will be easier and cheaper; ii) the return on investment is compelling; iii) leverage is feasible on the experiences of the Measles/Rubella initiative; iv) two disease eradication targets in one initiative are feasible and v) for the first time, an eradication investment case will inform the decisions. However, if previous eradication efforts have been marathons, measles eradication will need to be a sprint.

Rationale Positive allosteric modulators (PAMs) of type 5 metabotropic glutamate receptors (mGluR5) exert pro-cognitive effects in animal models of various neuropsychiatric diseases. However, few studies to date have examined ability of mGluR5 PAMs to reverse cognitive deficits in operant delayed matching/non-matching-to-sample (DMS/DNMS) tasks. Objectives To determine the ability of the mGluR5 PAM 3-cyano-N-1,3-diphenyl-1H-pyrazol-5-yl)benzamide (CDPPB) to reverse set-shifting deficits induced by the NMDA receptor antagonist MK-801. Methods Male Sprague-Dawley rats were initially trained to lever press for sucrose reinforcement under either DMS or DNMS conditions. Following successful acquisition of the task, reinforcement conditions were reversed (DNMS→DMS or DMS→DNMS). In Experiment 1, rats were treated daily prior to each session with either vehicle/vehicle, vehicle/MK-801 (0.06 mg/kg) simultaneously, CDPPB (20 mg/kg)/MK-801 simultaneously, or CDPPB 30 min prior to MK-801. In Experiment 2, rats were treated with either vehicle/vehicle, vehicle/MK-801, or CDPPB 30 min prior to MK-801 only prior to sessions that followed task reversal. Results In Experiment 1, no group differences in initial task acquisition were observed. Rats treated with vehicle+MK−801 showed significant set-shifting impairments following task reversal, which were partially attenuated by simultaneous administration of CDPPB/MK-801, and completely precluded by administration of CDPPB 30 min prior to MK-801. In Experiment 2, MK-801 did not impair reversal learning and no other group differences were observed. Conclusions MK-801 induced deficits in operant set-shifting ability were prevented by pretreatment with CDPPB. MK-801 did not produce deficits in initial task learning or when treatment was initiated following task reversal. PMID:24973895

Gaucher disease (GD) is amongst the most frequently occurring lysosomal storage disorder in all ethnicities. The clinical manifestations and natural history of GD is highly heterogeneous with extreme geographic and ethnic variations. The literature on GD has paucity of information and optimal management guidelines for Indian patients. Gaucher Disease Task Force was formed under the auspices of the Society for Indian Academy of Medical Genetics. Invited experts from various specialties formulated guidelines for the management of patients with GD. A writing committee was formed and the draft guidelines were circulated by email to all members for comments and inputs. The guidelines were finalized in December 2016 at the annual meeting of the Indian Academy of Medical Genetics. These guidelines are intended to serve as a standard framework for treating physicians and the health care systems for optimal management of Gaucher disease in India and to define unique needs of this patient population. Manifestations of GD are protean and a high index of suspicion is essential for timely diagnosis. Patients frequently experience diagnostic delays during which severe irreversible complications occur. Leucocyte acid b-glucosidase activity is mandatory for establishing the diagnosis of Gaucher disease; molecular testing can help identify patients at risk of neuronopathic disease. Enzyme replacement therapy for type 1 and type 3 Gaucher disease is the standard of care. Best outcomes are achieved by early initiation of therapy before onset of irreversible complications. However, in setting of progressive neurological symptoms such as seizures and or/ neuroregression, ERT is not recommended, as it cannot cross the blood brain barrier. The recommendations herein are for diagnosis, for initiation of therapy, therapeutic goals, monitoring and follow up of patients. We highlight that prevention of recurrence of the disease through genetic counseling and prenatal diagnosis is essential in India, due to uniformly severe phenotypes encountered in our population.

Graves' ophthalmopathy is the primary etiology for exophthalmos in adults. It is a complex orbital disease whose pathophysiology remains controversial. Since its initial description more than 150 years ago, its heterogeneous clinical manifestations and poorly understood links with thyroid pathology remain unresolved issues. Disease activity is the main determinant for the management of Graves' ophthalmopathy, but treatments are often symptomatic, aiming at decreasing orbital inflammation. We report a retrospective analysis of 30 patients diagnosed with Graves' ophthalmopathy followed in our department between 1991 and 2002. Following a phase of medical management of their disease, all patients underwent surgical orbital decompression. Medical and surgical care provided as well as results are presented with a mean follow-up of 23 months. Based on our clinical experience, new concepts in the field of Graves' ophthalmopathy are discussed. Disease activity, evaluated through various means, appears to be the primary guide for therapeutic management. Moreover, the importance of a multidisciplinary approach is highlighted, in order to improve the management of this difficult disorder.

2009-04-01

In recent years controversial discussions arose during major animal disease outbreaks in the EU about the ethical soundness of mass culling. In contrast to numerous publications about ethical issues and laboratory animals/animal experiments, literature concerning ethical deliberations in the case of mass culling as a means of outbreak control remain scarce. Veterinarians in charge of decision about and implementation of mass culling actions find themselves in an area of conflict in between the officially required animal disease control policy and a public that is increasingly critical. Those veterinarians are faced with the challenge to defend the relevant decisions against all stakeholders and also themselves. In this context an interdisciplinary workshop was initiated in Switzerland in October 2007 with ethicians and (official) veterinarians from Germany, Switzerland and Austria. With the aim to identify ethical components of animal disease control for official veterinarians, talks and moderated group discussions took place. This article summarizes selected discussion points and conclusions.

A family medicine training program in the Republic of Georgia: incorporating a model of chronic disease management.

Sanders, James

2007-01-01

This study describes a different approach to increase the number of family medicine physicians trained with specific competencies in the management of chronic disease. In 1999 the Republic of Georgia initiated an ambitious program designed to retrain practicing physicians in the specialty of family medicine. At 2 of the implementation sites, the Center for International Health worked with local health authorities to augment the official 940-hour curriculum to include lesson plans, workshops, and practicum experiences emphasizing a model of chronic disease management, giving particular attention to hypertension. The population served by the training sites has benefited in a cost-effective manner by achieving blood pressure control for as little as $8 per year per patient; the physician learners have performed above their peer group on standardized national testing. Family medicine training programs in resource-poor settings can incorporate chronic disease management models into their curriculum and achieve high-quality patient care outcomes.

Lower respiratory infections are among the leading causes of death worldwide. In this study, it was evaluated the interaction of indocyanine green, a photosensitizer activated by infrared light, with alveolar macrophages and the effectiveness of the photodynamic therapy using this compound against Streptococcus pneumoniae . Initial experiments analyzed indocyanine green toxicity to alveolar macrophages in the dark with different drug concentrations and incubation times, and macrophage viability was obtained with the MTT method. The average of the results showed viability values below 90% for the two highest concentrations. Experiments with Streptococcus pneumoniae showed photodynamic inactivation with 10 μM indocyanine green solution. Further experiments with the bacteria in co-culture with AM will be conducted verifying the photodynamic inactivation effectiveness of the tested drug concentrations and incubation periods using infrared light.

Accelerating Translational Research through Open Science: The Neuro Experiment.

Gold, E Richard

2016-12-01

Translational research is often afflicted by a fundamental problem: a limited understanding of disease mechanisms prevents effective targeting of new treatments. Seeking to accelerate research advances and reimagine its role in the community, the Montreal Neurological Institute (Neuro) announced in the spring of 2016 that it is launching a five-year experiment during which it will adopt Open Science-open data, open materials, and no patenting-across the institution. The experiment seeks to examine two hypotheses. The first is whether the Neuro's Open Science initiative will attract new private partners. The second hypothesis is that the Neuro's institution-based approach will draw companies to the Montreal region, where the Neuro is based, leading to the creation of a local knowledge hub. This article explores why these hypotheses are likely to be true and describes the Neuro's approach to exploring them.

To explore the experiences and adjustment modes of couples during the period between the initial signs of the Alzheimer's disease (AD) and the years following diagnosis, particularly in the case of early-onset AD. A dyadic interpretative phenomenological analysis was conducted with married couples in which one member of each couple received a diagnosis of probable early-onset AD (before 65 years of age). Sixteen young couples, followed by the National Reference Centre for Young Persons with AD, agreed to participate. For seven of the couples, the caregiver was a woman. The mean age was 57.4 (SD = 4.2) for the caregivers and 57.3 (SD = 4.1) for the persons with AD. The semi-structured interviews were conducted in the couples' homes. Each interview was conducted with both spouses to capture their interactions in the context of individual and shared experiences. Two higher-order themes emerged from the analyses: the 'need to know' and, after the diagnosis, the 'need not to know more'. Indeed, the first signs mark the beginning of a period of doubt and a search for understanding. This pursuit of knowledge progresses to the recognition of more intense and severe signs that encourage couples to seek medical attention. Both reassuring and destabilising, the diagnosis is a breaking point that modifies how the changes and painful effects associated with disease are experienced. Couples employ strategies to minimise their suffering and consequently their knowledge about the disease. These results show that the couples oscillate between the need to know and the fear of knowing. To protect themselves, they use strategies to reduce their suffering and to distance the disease. The use of these avoidance strategies indicates that certain times in the course of disease management are less appropriate for couples to accept the assistance offered by formal caregivers. © 2015 Nordic College of Caring Science.

Background In Europe, Spain has the highest number of people with Chagas disease (CD). Bolivian migrants account for 81% of the reported cases. One of the priorities in controlling the disease is prevention of mother-to-child transmission. Despite under-diagnosis in Spain being estimated at 90%, there are currently few studies that explore the social and cultural dimensions of this disease. Objective The aim of this study was to explore the knowledge and experiences of Bolivian women with CD, in order to generate a useful understanding for the design and implementation of public health initiatives. Design Qualitative study based on semi-structured interviews, triangular groups, and field notes. Participants Fourteen Bolivian women with CD living in Madrid. Results The participants were aware that the disease was transmitted through the vector, that it could be asymptomatic, and that it could also be associated with sudden death by heart failure. They opined that the treatment as such could not cure the disease but only slow it down. There was a sense of indifference along with a lack of understanding of the risk of contracting the disease. Participants who presented with symptoms, or those with relatives suffering from the disease, were concerned about fatalities, cardiac problems, and possible vertical transmission. There was also a fear of being rejected by others. The disease was described as something that affected a large number of people but only showed up in a few cases and that too after many years. There was a widespread assumption that it was better not to know because doing so, allows the disease to take hold. Conclusions Disease risk perception was very low in Bolivian women living in Madrid. This factor, together with the fear of being screened, may be contributing to the current rate of under-diagnosis.

The richly innervated corneal tissue is one of the most powerful pain generator in the body. Corneal neuropathic pain results from dysfunctional nerves causing perceptions such as burning, stinging, eye-ache and pain. Various inflammatory diseases, neurological diseases, and surgical interventions can be the underlying cause of corneal neuropathic pain. Recent efforts have been made by the scientific community to elucidate the pathophysiology and neurobiology of pain resulting from initially protective physiological reflexes, to a more persistent chronic state. The goal of this clinical review is to briefly summarize the pathophysiology of neuropathic corneal pain, describe how to systematically approach the diagnosis of these patients, and finally summarizing our experience with current therapeutic approaches for the treatment of corneal neuropathic pain.

Quantitative structural MRI for early detection of Alzheimer’s disease

PubMed Central

McEvoy, Linda K; Brewer, James B

2011-01-01

Alzheimer’s disease (AD) is a common progressive neurodegenerative disorder that is not currently diagnosed until a patient reaches the stage of dementia. There is a pressing need to identify AD at an earlier stage, so that treatment, when available, can begin early. Quantitative structural MRI is sensitive to the neurodegeneration that occurs in mild and preclinical AD, and is predictive of decline to dementia in individuals with mild cognitive impairment. Objective evidence of ongoing brain atrophy will be critical for risk/benefit decisions once potentially aggressive, disease-modifying treatments become available. Recent advances have paved the way for the use of quantitative structural MRI in clinical practice, and initial clinical use has been promising. However, further experience with these measures in the relatively unselected patient populations seen in clinical practice is needed to complete translation of the recent enormous advances in scientific knowledge of AD into the clinical realm.

During the last decade, Kaiser Permanente, an integrated health care delivery system with more than 60 years of experience in managing the care of individuals and populations, has applied the chronic care model (CCM) to develop care management strategies for populations of patients with chronic medical conditions. Physician leadership and involvement have been key to successfully incorporating these practices into care. The scope of physician involvement in leading, developing, and delivering chronic illness care management at Kaiser Permanente is described as a basis for identifying opportunities to involve practicing physicians in the CCI-I.

Psoriasis is one of the most common T cell–mediated autoimmune diseases in humans. Although a role for the innate immune system in driving the autoimmune T cell cascade has been proposed, its nature remains elusive. We show that plasmacytoid predendritic cells (PDCs), the natural interferon (IFN)-α–producing cells, infiltrate the skin of psoriatic patients and become activated to produce IFN-α early during disease formation. In a xenograft model of human psoriasis, we demonstrate that blocking IFN-α signaling or inhibiting the ability of PDCs to produce IFN-α prevented the T cell–dependent development of psoriasis. Furthermore, IFN-α reconstitution experiments demonstrated that PDC-derived IFN-α is essential to drive the development of psoriasis in vivo. These findings uncover a novel innate immune pathway for triggering a common human autoimmune disease and suggest that PDCs and PDC-derived IFN-α represent potential early targets for the treatment of psoriasis.

Summary Aspirin (ASA) is the mainstay of treatment in cerebrovascular and systemic vascular disease. ASA hypersensitivity can pose a challenge to achieving optimum medical management prior to and after neurointerventional treatment. Desensitization to ASA is well described in the allergy and cardiovascular literature, but there are no similar discussions specific to neurointervention. The purpose of our study was to describe our experience with ASA hypersensitivity management and review the relevant literature. Two cases of patients with symptomatic cerebrovascular disease requiring neurointervention who were successfully desensitized to their ASA hypersensitivity prior to treatment are described. The subsequent literature is reviewed. Several ASA desensitization protocols exist and have been proven to successfully treat ASA hypersensitivity and allow for ASA therapy to be safely initiated. We describe several previously published protocols. ASA desensitization is a safe and simple way to manage ASA hypersensitivity. We provide comprehensive management guidelines for the neurointerventionalist engaging in ASA desensitization. PMID:24556294

Blood coagulation is essential for physiological hemostasis but simultaneously contributes to thrombotic disease. However, molecular and cellular events controlling initiation and propagation of coagulation are still incompletely understood. In this study, we demonstrate an unexpected role of eosinophils during plasmatic coagulation, hemostasis, and thrombosis. Using a large-scale epidemiological approach, we identified eosinophil cationic protein as an independent and predictive risk factor for thrombotic events in humans. Concurrent experiments showed that eosinophils contributed to intravascular thrombosis by exhibiting a strong endogenous thrombin-generation capacity that relied on the enzymatic generation and active provision of a procoagulant phospholipid surface enriched in 12/15-lipoxygenase–derived hydroxyeicosatetraenoic acid–phosphatidylethanolamines. Our findings reveal a previously unrecognized role of eosinophils and enzymatic lipid oxidation as regulatory elements that facilitate both hemostasis and thrombosis in response to vascular injury, thus identifying promising new targets for the treatment of thrombotic disease.

The first human H5N1 case was diagnosed in Hong Kong in 1997. Since then, experience in effective preparedness strategies that target novel influenza viruses has expanded. Here, we report on avian influenza preparedness in public hospitals in Hong Kong to illustrate policies and practices associated with control of emerging infectious diseases. The Hong Kong government's risk-based preparedness plan for influenza pandemics includes 3 response levels for command, control, and coordination frameworks for territory-wide responses. The tiered levels of alert, serious, and emergency response enable early detection based on epidemiological exposure followed by initiation of a care bundle. Information technology, laboratory preparedness, clinical and public health management, and infection control preparedness provide a comprehensive and generalizable preparedness plan for emerging infectious diseases. © The Author 2017.

This is a personal account of how tumour necrosis factor (TNF) the prototype of a group of host-origin mediators, often known as pro-inflammatory cytokines, came into parasitology, and was subsequently realised to be central to the pathogenesis of most disease pathology. This contribution summarizes an example of how a curiosity-driven outsider, with initially no intention of heading this way, and no relevant experience, and with no more than the simplest of plans but an ambition to read as widely as it takes, and (most importantly) allowed to follow his head, can be what is required to give fresh insight into understanding a disease. It also gives the author's views on aspects of how the field of malaria disease pathogenesis seems to be developing. The hope is to inspire another generation to follow a similarly original course.

Age-related Macular Degeneration (AMD) is a kind of macular disease which mostly occurs in old people，and it may cause decreased vision or even lead to permanent blindness. Drusen is an important clinical indicator for AMD which can help doctor diagnose disease and decide the strategy of treatment. Optical Coherence Tomography (OCT) is widely used in the diagnosis of ophthalmic diseases, include AMD. In this paper, we propose a classification method based on Multiple Instance Learning (MIL) to detect AMD. Drusen can exist in a few slices of OCT images, and MIL is utilized in our method. We divided the method into two phases: training phase and testing phase. We train the initial features and clustered to create a codebook, and employ the trained classifier in the test set. Experiment results show that our method achieved high accuracy and effectiveness.

Imported malaria occurs as a relatively rare event in developed countries. As a consequence, most clinicians have little experience in making clinical assessments of disease severity and decisions regarding the need for parenteral therapy or high-level monitoring. In this study, the diagnostic accuracy of procalcitonin (PCT) for severe Plasmodium falciparum disease was assessed in a cohort of 100 consecutive travellers with various species of imported malaria. In all patients, PCT was measured on admission with a semi-quantitative 'point-of-care' test. Patients with severe P. falciparum malaria had significantly higher median PCT levels on admission as compared with patients with uncomplicated P. falciparum disease. In addition, PCT levels in patients with non-falciparum malaria were also higher compared with patients with non-severe falciparum malaria but lower compared with severe P. falciparum malaria. At a cut-off point of 10 ng/mL, PCT had a sensitivity of 0,67 and a specificity of 0,94 for severe falciparum disease. However, at lower cut-off points the specificity and positive predictive value were rather poor although the sensitivity and negative predictive value remained high. Potential drawbacks in the interpretation of elevated PCT levels on admission may be caused by infections with non-falciparum species and by concomitant bacterial infections. Semi-quantitative determination of PCT on admission is of limited use in the initial clinical assessment of disease severity in travellers with imported malaria, especially in settings with limited experience with the treatment of malaria.

Two strains of freshwater-reared coho salmon Oncorhynchus kisutch were compared for differences in the activity of selected non-specific immune factors before and after lethal and non-lethal immersion challenges with the marine bacterial pathogen Vibrio anguillarum (Vang). Two disease challenge experiments were performed. The first experimental challenge resulted in no mortality; however, significant strain and challenge treatment effects were detected at Day 16 post-challenge. Strain differences in plasma lysozyme activity were found in pre-challenge samples. The second challenge experiment compared the same strains of coho salmon following immersion challenges in different doses of Vang. The fish were sampled at Days 0, 2, 7, and 18 post-challenge and mortality, plasma lysozyme, and anterior kidney phagocyte respiratory burst activity were compared. There were significant strain differences in mortality in the high dose group. The more disease-resistant strain was found to have higher levels of plasma lysozyme and anterior kidney phagocyte respiratory burst activity. These strain differences were detected at various times in the lethal (high dose) and non-lethal challenge groups. There was a clear relationship between the enhanced survival of the more disease-resistant strain and a more sustained, elevated non-specific immune response following the experimental disease challenges. The results of this study suggest that the basis for strain differences in innate disease resistance is related to the ability of the fish to respond quickly to the initial infection and to maintain the response until the infection is quelled.

Overwork-related disorders, such as cerebrovascular/cardiovascular diseases (CCVD) and mental disorders due to overwork, are a major occupational and public health issue worldwide, particularly in East Asian countries. This report discusses the recent trend of overwork-related disorders in Japan from the perspective of workers' compensated occupational diseases, as well as the development of a national policy for preventive measures against overwork-related disorders in Japan. Recently, the number of claimed and compensated cases of occupational mental disorders has increased substantially, particularly among young workers, as compared to those of occupational CCVD. In response to these situations and action from society, the Japanese Government passed the "Act on Promotion of Preventive Measures against Karoshi and Other Overwork-Related Health Disorders" in June 2014 to develop a national initiative towards the prevention of overwork-related disorders. Changes in the trend of overwork-related disorders in Japan under a legal foundation and an initiative by the central government should be closely monitored so that other countries can benefit from the experiences.

Multiple system atrophy is a neurodegenerative disease that affects autonomic and motor systems. Patients with multiple system atrophy usually experience lower urinary tract symptoms, which sometimes appear as an initial symptom before the emergence of the generalized symptoms. An open bladder neck during the filling phase on video urodynamic study is one characteristic imaging finding after the diagnosis of multiple system atrophy, but has not previously been reported at an early phase of the disease. We report a case in which an open bladder neck was observed on several imaging modalities before generalized symptoms emerged. Because occult neurogenic bladder might exist in patients whose lower urinary tract symptoms are resistant to pharmacotherapy, we report this case to raise awareness of the importance of sufficient imaging evaluations. An open bladder neck might be an important imaging finding for diagnosing multiple system atrophy, irrespective of the presence of generalized symptoms. This finding could help avoid false diagnosis and unnecessary treatment. © 2017 The Japanese Urological Association.

2017-06-01

A unique primary prevention effort, Strong Communities for Children (Strong Communities), focuses on changing attitudes and expectations regarding communities' collective responsibilities for the safety of children. Findings from a 6-year pilot of the initiative in South Carolina have shown promise in reducing child maltreatment, but efforts to adapt the initiative to different cultural contexts have been lacking. No models exist for adapting an initiative that takes a community-level approach to ensuring children's safety. Thus, this article addresses the gap by providing an overview of the original initiative, how the initiative was adapted to the Israeli context, and lessons learned from the experience. Building on conceptualizations of cultural adaptation by Castro et al. (Prevention Science, 5, 2004, 41) and Resnicow et al. (Ethnicity and Disease, 9, 1999, 11), sources of nonfit (i.e., sociodemographic traits, political conflict, government services, and the presence and role of community organizations) were identified and deep and surface structure modifications were made to the content and delivery. Ultimately, this article describes the adaption and dissemination of a community-based child maltreatment prevention initiative in Tel Aviv, Israel, and addresses researchers' calls for more publications describing the adaptation of interventions and the procedures that need to be implemented to achieve cultural relevance. © 2015 Family Process Institute.

A Focused Ethnographic Study of Sri Lankan Government Field Veterinarians’ Decision Making about Diagnostic Laboratory Submissions and Perceptions of Surveillance

The global public health community is facing the challenge of emerging infectious diseases. Historically, the majority of these diseases have arisen from animal populations at lower latitudes where many nations experience marked resource constraints. In order to minimize the impact of future events, surveillance of animal populations will need to enable prompt event detection and response. Many surveillance systems targeting animals rely on veterinarians to submit cases to a diagnostic laboratory or input clinical case data. Therefore understanding veterinarians’ decision-making process that guides laboratory case submission and their perceptions of infectious disease surveillance is foundational to interpreting disease patterns reported by laboratories and engaging veterinarians in surveillance initiatives. A focused ethnographic study was conducted with twelve field veterinary surgeons that participated in a mobile phone-based surveillance pilot project in Sri Lanka. Each participant agreed to an individual in-depth interview that was recorded and later transcribed to enable thematic analysis of the interview content. Results found that field veterinarians in Sri Lanka infrequently submit cases to laboratories – so infrequently that common case selection principles could not be described. Field veterinarians in Sri Lanka have a diagnostic process that operates independently of laboratories. Participants indicated a willingness to take part in surveillance initiatives, though they highlighted a need for incentives that satisfy a range of motivations that vary among field veterinarians. This study has implications for the future of animal health surveillance, including interpretation of disease patterns reported, system design and implementation, and engagement of data providers.

Initial experiences are reviewed in an integrated operation theater equipped with an intraoperative high-field (1.5 T) magnetic resonance (MR) imager and neuro-navigation (BrainSUITE), to evaluate the indications and limitations. One hundred consecutive cases were treated, consisting of 38 gliomas, 49 other tumors, 11 cerebrovascular diseases, and 2 functional diseases. The feasibility and usefulness of the integrated theater were evaluated for individual diseases, focusing on whether intraoperative images (including diffusion tensor imaging) affected the surgical strategy. The extent of resection and outcomes in each histological category of brain tumors were examined. Intraoperative high-field MR imaging frequently affected or modified the surgical strategy in the glioma group (27/38 cases, 71.1%), but less in the other tumor group (13/49 cases, 26.5%). The surgical strategy was not modified in cerebrovascular or functional diseases, but the success of procedures and the absence of complications could be confirmed. In glioma surgery, subtotal or greater resection was achieved in 22 of the 31 patients (71%) excluding biopsies, and intraoperative images revealed tumor remnants resulting in the extension of resection in 21 of the 22 patients (95.4%), the highest rate of extension among all types of pathologies. The integrated neuro-navigation improved workflow. The best indication for intraoperative high-field MR imaging and integrated neuro-navigation is brain tumors, especially gliomas, and is supplementary in assuring quality in surgery for cerebrovascular or functional diseases. Immediate quality assurance is provided in several types of neurosurgical procedures.

Collaboration between traditional healers and biomedical practitioners is now being accepted by many African countries south of the Sahara because of the increasing problem of HIV/AIDS. The key problem, however, is how to initiate collaboration between two health systems which differ in theory of disease causation and management. This paper presents findings on experience learned by initiation of collaboration between traditional healers and the Institute of Traditional Medicine in Arusha and Dar-es-Salaam Municipalities, Tanzania where 132 and 60 traditional healers respectively were interviewed. Of these 110 traditional healers claimed to be treating HIV/AIDS. The objective of the study was to initiate sustainable collaboration with traditional healers in managing HIV/AIDS. Consultative meetings with leaders of traditional healers' associations and government officials were held, followed by surveys at respective traditional healers' "vilinge" (traditional clinics). The findings were analysed using both qualitative and quantitative methods. The findings showed that influential people and leaders of traditional healers' association appeared to be gatekeepers to access potential good healers in the two study areas. After consultative meetings these leaders showed to be willing to collaborate; and opened doors to other traditional healers, who too were willing to collaborate with the Institute of Traditional Medicine in managing HIV/AIDS patients. Seventy five percent of traditional healers who claimed to be treating HIV/AIDS knew some HIV/AIDS symptoms; and some traditional healers attempted to manage these symptoms. Even though, they were willing to collaborate with the Institute of Traditional Medicine there were nevertheless some reservations based on questions surrounding sharing from collaboration. The reality of past experiences of mistreatment of traditional healers in the colonial period informed these reservations. General findings suggest that initiating collaboration is not as easy as it appears to be from the literature, if it is to be meaningful; and thus we are calling for appropriate strategies to access potential healers targeted for any study designed with sustainability in mind.

Due to the high volume of travel and the spread of various diseases as well as disorders during a trip, one of the major concerns for travelers is the issues related to disease spread, control, and prevention. The approach of philosophers and traditional physicians along with hygiene measures were noted as trip recommendations in their textbooks. Considering negligence in disease prevention and the lack of dedicated and systematic discussion on this topic, this article aims at collecting their experiences as a practical reference point. This qualitative study, review articles in the field of traditional medicine and search in authentic books on traditional medicine. The gathered data were initially analyzed and then categorized. Results were described in several sub-categories, including general recommendation, food and drinking recommendations during travel, prevention of dehydration in warm and cold conditions, poisoned and polluted air recommendations, management of sea passengers, fatigue due to travel, and the prevention of skin diseases. These measures are efficient interventions and cost-effective, which provide guidelines for traveler's health during a trip.

Observed and Normative Discount Functions in Addiction and other Diseases

2017-01-01

The aim of this paper is to find a suitable discount function able to describe the progression of a certain addiction or disease under treatment as a discounting process. In effect, a certain indicator related to a disease decays over time in a manner which is mathematically similar to the way in which discounting has been modeled. We analyze the discount functions observed in experiments which study addictive and other problematic behaviors as well as some alternative hyperbola-like discount functions in order to fit the patience exhibited by the subject after receiving the treatment. Additionally, it has been experimentally found that people with addiction display high rates of discount (impatience) and preference reversals (dynamic inconsistency). This excessive discounting must be correctly modeled by a suitable discount function, otherwise, it can become a trans-disease process underlying addiction and other disorders. The (generalized) exponentiated hyperbolic discount function is proposed to describe the progression of a disease with respect to the treatment, since it maintains the property of inconsistency by exhibiting a decreasing discount rate after an initial period in which the opposite occurs.

Background and Objectives: The experience with treatment of diverticular colon disease (DCD) by the laparoscopic method is analyzed. Methods: Between January 1994 and July 1997, a group of 22 patients with criteria for symptomatic diverticular disease in the descending and sigmoid colon underwent laparoscopy with average resections of 40 cm. Intra-abdominal mechanical anastomosis completed the procedure. Results: The operative morbidity was 28%. Two cases, in acute diverticulitis phase, were reconverted to open surgery, and three cases presented postoperative rectorrhagia which ceased spontaneously. No long-term complications have been found. Postoperative hospitalization was 4-8 days (mean 5.5) and mean operative time was 165 minutes (range 120-240). Conclusions: Nevertheless, the learning curve precise to practice this type of surgery, the acceptable morbity-mortality rates which the laparoscopic method presents, especially with these high-risk groups of patients (age > 65, high blood pressure, etc), encouraged us to modified the criteria indicating surgery for the disease, offering first choice operative treatment with efficiency and safety. However, we feel that those patients with acute complications of diverticular colon disease must be excluded initially for laparoscopic approach. PMID:9876730

Adult congenital heart disease patients present a unique challenge to the cardiac imager. Patients may present with both acute and chronic manifestations of their complex congenital heart disease and also require surveillance for sequelae of their medical and surgical interventions. Multimodality imaging is often required to clarify their anatomy and physiology. Radiation dose is of particular concern in these patients with lifelong imaging needs for their chronic disease. The second-generation dual-source scanner is a recently available advanced clinical cardiac computed tomography (CT) scanner. It offers a combination of the high-spatial resolution of modern CT, the high-temporal resolution of dual-source technology, and the wide z-axis coverage of modern cone-beam geometry CT scanners. These advances in technology allow novel protocols that markedly reduce scan time, significantly reduce radiation exposure, and expand the physiologic imaging capabilities of cardiac CT. We present a case series of complicated adult congenital heart disease patients imaged by the second-generation dual-source CT scanner with extremely low-radiation doses and excellent image quality. © 2012 Wiley Periodicals, Inc.

Animal models of Helicobacter-induced disease: methods to successfully infect the mouse.

Taylor, Nancy S; Fox, James G

2012-01-01

Animal models of microbial diseases in humans are an essential component for determining fulfillment of Koch's postulates and determining how the organism causes disease, host response(s), disease prevention, and treatment. In the case of Helicobacter pylori, establishing an animal model to fulfill Koch's postulates initially proved so challenging that out of frustration a human volunteer undertook an experiment to become infected with H. pylori and to monitor disease progression in order to determine if it did cause gastritis. For the discovery of the organism and his fulfillment of Koch's postulates he and a colleague were awarded the Nobel Prize in Medicine. After H. pylori was established as a gastric pathogen, it took several years before a model was developed in mice, opening the study of the organism and its pathogenicity to the general scientific community. However, while the model is widely utilized, there are a number of difficulties that can arise and need to be overcome. The purpose of this chapter is to raise awareness regarding the problems, and to offer reliable protocols for successfully establishing the H. pylori mouse model.

Objective People with chronic liver disease, particularly those with decompensated cirrhosis, experience several potentially debilitating complications that can have a significant impact on activities of daily living and quality of life. These impairments combined with the associated complex treatment mean that they are faced with specific and high levels of supportive care needs. We aimed to review reported perspectives, experiences and concerns of people with chronic liver disease worldwide. This information is necessary to guide development of policies around supportive needs screening tools and to enable prioritisation of support services for these patients. Design Systematic searches of PubMed, MEDLINE, CINAHL and PsycINFO from the earliest records until 19 September 2014. Data were extracted using standardised forms. A qualitative, descriptive approach was utilised to analyse and synthesise data. Results The initial search yielded 2598 reports: 26 studies reporting supportive care needs among patients with chronic liver disease were included, but few of them were patient-reported needs, none used a validated liver disease-specific supportive care need assessment instrument, and only three included patients with cirrhosis. Five key domains of supportive care needs were identified: informational or educational (eg, educational material, educational sessions), practical (eg, daily living), physical (eg, controlling pruritus and fatigue), patient care and support (eg, support groups), and psychological (eg, anxiety, sadness). Conclusions While several key domains of supportive care needs were identified, most studies included hepatitis patients. There is a paucity of literature describing the supportive care needs of the chronic liver disease population likely to have the most needs—namely those with cirrhosis. Assessing the supportive care needs of people with chronic liver disease have potential utility in clinical practice for facilitating timely referrals to support services. PMID:25854973

Systemic rapamycin to prevent in-stent stenosis in peripheral pulmonary arterial disease: early clinical experience.

2016-10-01

We have taken a novel approach using oral rapamycin - sirolimus - as a medical adjunct to percutaneous therapy in patients with in-stent stenosis and high risk of right ventricular failure. Peripheral pulmonary artery stenosis can result in right ventricular hypertension, dysfunction, and death. Percutaneous pulmonary artery angioplasty and stent placement acutely relieve obstructions, but patients frequently require re-interventions due to re-stenosis. In patients with tetralogy of Fallot or arteriopathy, the problem of in-stent stenosis contributes to the rapidly recurrent disease. Rapamycin was administered to 10 patients (1.5-18 years) with peripheral pulmonary stenosis and in-stent stenosis and either right ventricular hypertension, pulmonary blood flow maldistribution, or segmental pulmonary hypertension. Treatment was initiated around the time of catheterisation and continued for 1-3 months. Potential side-effects were monitored by clinical review and blood tests. Target serum rapamycin level (6-10 ng/ml) was accomplished in all patients; eight of the nine patients who returned for clinically indicated catheterisations demonstrated reduction in in-stent stenosis, and eight of the 10 patients experienced no significant side-effects. Among all, one patient developed diarrhoea requiring drug discontinuation, and one patient experienced gastrointestinal bleeding while on therapy that was likely due to an indwelling feeding tube and this patient tolerated rapamycin well following tube removal. Our initial clinical experience supports that patients with peripheral pulmonary artery stenosis can be safely treated with rapamycin. Systemic rapamycin may provide a novel medical approach to reduce in-stent stenosis.

Cognitive behavioural therapy for the management of inflammatory bowel disease-fatigue with a nested qualitative element: study protocol for a randomised controlled trial.

PubMed

Fatigue is one of the most prevalent and burdensome symptoms for patients with inflammatory bowel disease (IBD). Although fatigue increases during periods of inflammation, for some patients it persists when disease is in remission. Compared to other long-term conditions where fatigue has been extensively researched, optimal management of fatigue in patients with IBD is unknown and fatigue has rarely been the primary outcome in intervention studies. To date, interventions for the management of IBD-fatigue are sparse, have short-term effects and have not been implemented within the existing health system. There is a need to integrate current best evidence across different conditions, patient experience and clinical expertise in order to develop interventions for IBD-fatigue management that are feasible and effective. Modifying an existing intervention for patients with multiple sclerosis, this study aims to assess the feasibility and initial estimates of efficacy of a cognitive behavioural therapy (CBT) intervention for the management of fatigue in patients with IBD. The study will be a two-arm pilot randomised controlled trial. Patients will be recruited from one outpatient IBD clinic and randomised individually to either: Group 1 (CBT manual for the management of fatigue, one 60-min session and seven 30-min telephone/Skype sessions with a therapist over an eight-week period); or Group 2 (fatigue information sheet to use without therapist help). Self-reported IBD-fatigue (Inflammatory Bowel Disease-Fatigue Scale) and IBD-quality of life (United Kingdom Inflammatory Bowel Disease Questionnaire) and self-reported disease activity will be collected at baseline, three, six and 12 months post randomisation. Illness perceptions, daytime sleepiness, anxiety and depression explanatory variables will be collected only at three months post randomisation. Clinical and sociodemographic data will be retrieved from the patients' medical notes. A nested qualitative study will evaluate patient and therapist experience, and healthcare professionals' perceptions of the intervention. The study will provide evidence of the feasibility and initial estimates of efficacy of a CBT intervention for the management of fatigue in patients with IBD. Quantitative and qualitative findings from the study will contribute to the development and implementation of a large-scale randomised controlled trial assessing the efficacy of CBT interventions for IBD-fatigue.

Salvage Lenvatinib Therapy in Metastatic Anaplastic Thyroid Cancer.

2017-07-01

Historical anaplastic thyroid cancer (ATC) outcomes have been terrible, with a median survival of only five months and <20% one-year survival. Improved outcomes are now achieved with aggressive initial therapy in stages IVA and IVB disease, but patients with distant metastatic disease (stage IVC) still do poorly; improved therapies are sorely needed. Kinase inhibitors have emerged as promising agents in the therapy of advanced medullary and differentiated thyroid cancer, but there are limited data regarding the use of lenvatinib in ATC. The aim of this study was to delineate clinical outcomes in a series of patients with advanced ATC in response to lenvatinib therapy. A retrospective analysis was conducted involving all lenvatinib-treated Mayo Clinic ATC patients in 2015. Of 28 distinct ATC patients seen in 2015, three (11%) with metastatic disease of ECOG performance status 2-3 were treated with lenvatinib. Two patients were male; age range at ATC diagnosis was 57-84 years. All three patients attained successful local control of their disease with surgery and/or combined chemoradiotherapy. Lenvatinib was offered as the second, third, or fourth line of therapy at the time of metastatic disease progression. Two patients incurred minor responses to therapy, with structural regression of distant metastatic tumor disease soon after starting lenvatinib treatment (at one to two months), while one patient achieved stable disease, but no Response Evaluation Criteria In Solid Tumors partial responses resulted. Overall survival after starting lenvatinib was two, six, and seven months. Fatigue and hypertension were prominent, and one patient developed pulmonary emboli while on lenvatinib. This initial single-institution experience suggests that lenvatinib may have some disease-modifying activity in metastatic ATC that is otherwise refractory to cytotoxic chemotherapy. Unfortunately, observed benefits were transient, and toxicities were prominent. Clinical trials are required to ascertain better the utility of lenvatinib in the management of advanced ATC.

Cerebral Activations Related to Ballistic, Stepwise Interrupted and Gradually Modulated Movements in Parkinson Patients

Patients with Parkinson’s disease (PD) experience impaired initiation and inhibition of movements such as difficulty to start/stop walking. At single-joint level this is accompanied by reduced inhibition of antagonist muscle activity. While normal basal ganglia (BG) contributions to motor control include selecting appropriate muscles by inhibiting others, it is unclear how PD-related changes in BG function cause impaired movement initiation and inhibition at single-joint level. To further elucidate these changes we studied 4 right-hand movement tasks with fMRI, by dissociating activations related to abrupt movement initiation, inhibition and gradual movement modulation. Initiation and inhibition were inferred from ballistic and stepwise interrupted movement, respectively, while smooth wrist circumduction enabled the assessment of gradually modulated movement. Task-related activations were compared between PD patients (N = 12) and healthy subjects (N = 18). In healthy subjects, movement initiation was characterized by antero-ventral striatum, substantia nigra (SN) and premotor activations while inhibition was dominated by subthalamic nucleus (STN) and pallidal activations, in line with the known role of these areas in simple movement. Gradual movement mainly involved antero-dorsal putamen and pallidum. Compared to healthy subjects, patients showed reduced striatal/SN and increased pallidal activation for initiation, whereas for inhibition STN activation was reduced and striatal-thalamo-cortical activation increased. For gradual movement patients showed reduced pallidal and increased thalamo-cortical activation. We conclude that PD-related changes during movement initiation fit the (rather static) model of alterations in direct and indirect BG pathways. Reduced STN activation and regional cortical increased activation in PD during inhibition and gradual movement modulation are better explained by a dynamic model that also takes into account enhanced responsiveness to external stimuli in this disease and the effects of hyper-fluctuating cortical inputs to the striatum and STN in particular.

To identify specific actions for patient-centred quality improvement in chronic disease outpatient settings, this study identified patients' general and specific preferences among a comprehensive suite of initiatives for change. A cross-sectional survey was conducted in three hospital-based clinics specializing in oncology, neurology and cardiology care located in New South Wales, Australia. Adult English-speaking outpatients completed the touch-screen Consumer Preferences Survey in waiting rooms or treatment areas. Participants selected up to 23 general initiatives that would improve their experience. Using adaptive branching, participants could select an additional 110 detailed initiatives and complete a relative prioritization exercise. A total of 541 individuals completed the survey (71.1% consent, 73.1% completion). Commonly selected general initiatives, presented in order of decreasing priority (along with sample proportion), included: improved parking (60.3%), up-to-date information provision (15.0%), ease of clinic contact (12.9%), access to information at home (12.8%), convenient appointment scheduling (14.2%), reduced wait-times (19.8%) and information on medical emergencies (11.1%). To address these general initiatives, 40 detailed initiatives were selected by respondents. Initiatives targeting service accessibility and information provision, such as parking and up-to-date information on patient prognoses and progress, were commonly selected and perceived to be of relatively greater priority. Specific preferences included the need for clinics to provide patient-designated parking in close proximity to the clinic, information on treatment progress and test results (potentially in the form of designated brief appointments or via telehealth) and comprehensive and trustworthy lists of information sources to access at home. © The Author 2016.

2015-01-01

To identify the intangible elements that characterize the successful effort to fight Chagas disease in the Americas, determine how they contributed to the overall success of the partnership, and learn lessons from the experience that could be applied to other programs. This study was based on the Partnership Assessment Tool (PAT) developed by the Nuffield Institute for Health ("the Institute") at the University of Leeds (London). The PAT draws heavily on scientific literature and the extensive experience of sociologists and health experts working for the Institute. The Pan American Health Organization (PAHO) modified the tool slightly to adapt it to its needs and provide a general structure for the study. The six key principles of the PAT framework were applied in the design of the research questionnaires. The findings show that a successful collaboration requires a clear objective; a good-quality pool of data; and comprehensive qualitative and quantitative knowledge of the problem, its dimensions, and its impact. The collaboration was elaborated from a common idea and a shared, quantified plan based on data gathered by independent scientists plus a strategy with explicit milestones. The clarity of purpose allowed for an improved synergy of efforts and made it possible to resolve differences in opinions and approaches. PAHO's experience with effective collaborations such as the joint initiative to fight Chagas disease provides a rich knowledge base for analysis of the advantages, limitations, and paradigms of community involvement, collaborative practices, and partnerships.

Merck is implementing a question-based Translational Medicine Guide (TxM Guide) beginning as early as lead optimization into its stage-gate drug development process. Initial experiences with the TxM Guide, which is embedded into an integrated development plan tailored to each development program, demonstrated opportunities to improve target understanding, dose setting (i.e., therapeutic index), and patient subpopulation selection with more robust and relevant early human-based evidence, and increased use of biomarkers and simulations. The TxM Guide is also helping improve organizational learning, costs, and governance. It has also shown the need for stronger external resources for validating biomarkers, demonstrating clinical utility, tracking natural disease history, and biobanking. Copyright © 2016 The Authors.

The Breast Imaging Reporting and Data System® (BI-RADS®) initiative, instituted by the ACR, was begun in the late 1980s to address a lack of standardization and uniformity in mammography practice reporting. An important component of the BI-RADS initiative is the lexicon, a dictionary of descriptors of specific imaging features. The BI-RADS lexicon has always been data driven, using descriptors that previously had been shown in the literature to be predictive of benign and malignant disease. Once established, the BI-RADS lexicon provided new opportunities for quality assurance, communication, research, and improved patient care. The history of this lexicon illustrates a series of challenges and instructive successes that provide a valuable guide for other groups that aspire to develop similar lexicons in the future.

2014-01-01

Cyclooxygenase-2 is expressed early in colon carcinogenesis and plays crucial role in the progress of the disease. Recently, we found that α-lactalbumin had anti-inflammatory activity by inhibiting cyclooxygenase-2. In experiment 1, we investigated the effects of α-lactalbumin on the colon carcinogenesis initiated with azoxymethane (AOM) followed by promotion with dextran sodium sulfate (DSS) in mice. Dietary treatment with α-lactalbumin decreased fecal occult blood score at 3 days after DSS intake. α-Lactalbumin also decreased the colon tumor at week 9. In experiment 2, AOM-treated mice were sacrificed at 7 days after DSS intake. The plasma and colon prostaglandin E2 (PGE2) levels in AOM/DSS-treated mice were higher than those in the DSS-treated mice without initiation by AOM. α-Lactalbumin decreased PGE2 in both plasma and colon. These results suggest that α-lactalbumin effectively inhibited colon carcinogenesis, and the inhibition may be due to the decreased PGE2 by inhibiting cyclooxygenase-2 at cancer promotion stages.

2017-01-01

Background . Creutzfeldt-Jakob disease is a rare disorder of the central nervous system. Its initial diagnosis may be obscured by its variable presentation. This case report illustrates the complexity of diagnosing this disease early in the clinical course, especially when the initial symptoms may be psychiatric. It offers a brief review of the literature and reinforces a role for consultation psychiatry services. Methods . PUBMED/MEDLINE was searched using the terms "Creutzfeldt-Jakob disease", "psychiatric symptoms", "conversion disorder", "somatic symptom disorder", "functional movement disorder", and "functional neurologic disorder". Case . The patient was a 64-year-old woman with no prior psychiatric history who was initially diagnosed with conversion disorder and unspecified anxiety disorder but soon thereafter was discovered to have Creutzfeldt-Jakob disease. Discussion . This case highlights the central role of psychiatric symptoms in early presentations of Creutzfeldt-Jakob disease. Still, few other cases in the literature report functional neurological symptoms as an initial sign. The consultation psychiatrist must remain alert to changing clinical symptoms, especially with uncharacteristic disease presentations.

Disease spread across multiple scales in a spatial hierarchy: effect of host spatial structure and of inoculum quantity and distribution.

PubMed

Gosme, Marie; Lucas, Philippe

2009-07-01

Spatial patterns of both the host and the disease influence disease spread and crop losses. Therefore, the manipulation of these patterns might help improve control strategies. Considering disease spread across multiple scales in a spatial hierarchy allows one to capture important features of epidemics developing in space without using explicitly spatialized variables. Thus, if the system under study is composed of roots, plants, and planting hills, the effect of host spatial pattern can be studied by varying the number of plants per planting hill. A simulation model based on hierarchy theory was used to simulate the effects of large versus small planting hills, low versus high level of initial infections, and aggregated versus uniform distribution of initial infections. The results showed that aggregating the initially infected plants always resulted in slower epidemics than spreading out the initial infections uniformly. Simulation results also showed that, in most cases, disease epidemics were slower in the case of large host aggregates (100 plants/hill) than with smaller aggregates (25 plants/hill), except when the initially infected plants were both numerous and spread out uniformly. The optimal strategy for disease control depends on several factors, including initial conditions. More importantly, the model offers a framework to account for the interplay between the spatial characteristics of the system, rates of infection, and aggregation of the disease.

Enhancing acute myeloid leukemia therapy - monitoring response using residual disease testing as a guide to therapeutic decision-making.

PubMed

Tomlinson, Benjamin; Lazarus, Hillard M

2017-06-01

Current standards for monitoring the response of acute myeloid leukemia (AML) are based on morphologic assessments of the bone marrow and recovery of peripheral blood counts. A growing experience is being developed to enhance the detection of small amounts of AML, or minimal residual disease (MRD). Areas covered: Available techniques include multi-color flow cytometry (MFC) of leukemia associated immunophenotypes (LAIP), quantitative reverse transcriptase polymerase chain reaction (QRT-PCR) for detecting fusion and mutated genes (RUNX1-RUNX1T1, CBFB-MYH11, and NPM1), overexpression of genes such as WT1, and next generation sequencing (NGS) for MRD. Expert commentary: While MRD monitoring is standard of care in some leukemia subsets such as acute promyelocytic leukemia, this approach for the broader AML population does not universally predict outcomes as some patients may experience relapse in the setting of undetectable leukemia while others show no obvious disease progression despite MRD positivity. However, there are instances where MRD can identify patients at increased risk for relapse that may change recommended therapy. Currently, prospective investigations to define clinically relevant MRD thresholds are ongoing. Risk-adapted trials are needed to best define the use of MRD in the follow up of AML patients after initial induction therapy.

Initiation of reflective frames in counseling for Huntingtons Disease predictive testing.

2004-04-01

Genetic professionals and clients are likely to assign different meanings to the extended format of the counseling protocols for predictive testing. In order to facilitate informed, client-centered decisions about the possibility of predictive testing, counselors routinely use the question format to initiate what we call "reflective frames" that invite clients to discuss their feelings and encourage them to adopt introspective and self-reflective stances toward their own experience--spanning the past, the present, and the hypothetical future. We suggest that such initiations of reflective frames constitute a key element of counselors' nondirective stance, although the exact nature of their formulations can be complex and varied. Examining 24 Huntington's Disease (HD) clinic sessions involving 12 families in South Wales with the tools of discourse analysis, our focus in this paper is twofold: (i) to propose a classification of six types of reflective questions (e.g. nonspecific invites, awareness and anxiety, decision about testing, impact of result, dissemination, and other) and to examine their distribution across the various clinic appointments, and (ii) to investigate the scope of these questions in terms of temporal and social axes. We link our analysis to the current debate within the genetic counseling profession about the merits of reflection- versus information-focused counseling styles and the need to abide by professionally warranted and institutionally embedded counseling protocols.

Sex trafficking remains a flagrant violation of human rights, creating many public health concerns. During the initiation period, these victims experience acts of violence including gang rapes, subjecting them to traumatic injuries that include burns. Furthermore, lack of access to health care, particularly surgical, keeps them from receiving treatment for these functionally debilitating contractures caused by burns. This piece provides an overview of burns among sex-trafficked victims in India and the efforts by Cents of Relief to address the associated surgical burden of disease. PMID:25191142

In terms of policy, research, quality improvement, and practice-based learning, there are essential principles--namely, quality, effectiveness, and value of care--needed to navigate changes in the current and future US health care environment. Patient-centered outcome measurement lies at the core of all 3 principles. Multiple measures of disease-specific disability, generic health-related quality of life, and preference-based health state have been introduced to quantify disease impact and define effectiveness of care. This paper reviews the basic principles of patient outcome measurement and commonly used outcome instruments. The authors provide examples of how utilization of outcome measurement tools in everyday neurosurgical practice can facilitate practice-based learning, quality improvement, and real-world comparative effectiveness research, as well as promote the value of neurosurgical care.

Information, consent and treatment of patients with Morgellons disease: an ethical perspective.

PubMed

Söderfeldt, Ylva; Groß, Dominik

2014-04-01

Morgellons is a medically contested diagnosis with foremost dermatological symptoms. Patients experience fibers emerging from the skin, together with a range of other somatic, psychiatric, and neurological complaints. Within the medical community, it is generally held to be a variation of delusional parasitosis/delusional infestation, which is usually treated with antipsychotics. Little attention has been paid in the literature to the ethical aspects of treating patients with Morgellons disease. The communicative strategies suggested in the literature display significant ethical issues, primarily the use of therapeutic privilege, i.e. withholding information from the patient. Since this limits patient autonomy, that approach is ethically problematic. Instead, the physician has an ethical obligation to respect the patient's autonomy, provide full information, and seek consent before initiating a psychiatric referral.

Management of severe asthma: targeting the airways, comorbidities and risk factors.

PubMed

Gibson, Peter G; McDonald, Vanessa M

2017-06-01

Severe asthma is a complex heterogeneous disease that is refractory to standard treatment and is complicated by multiple comorbidities and risk factors. In mild to moderate asthma, the burden of disease can be minimised by inhaled corticosteroids, bronchodilators and self-management education. In severe asthma, however, management is more complex. When patients with asthma continue to experience symptoms and exacerbations despite optimal management, severe refractory asthma (SRA) should be suspected and confirmed, and other aetiologies ruled out. Once a diagnosis of SRA is established, patients should undergo a systematic and multidimensional assessment to identify inflammatory endotypes, risk factors and comorbidities, with targeted and individualised management initiated. We describe a practical approach to assessment and management of patients with SRA. © 2017 Royal Australasian College of Physicians.

Computer-assisted initial diagnosis of rare diseases

Introduction. Most documented rare diseases have genetic origin. Because of their low individual frequency, an initial diagnosis based on phenotypic symptoms is not always easy, as practitioners might never have been exposed to patients suffering from the relevant disease. It is thus important to develop tools that facilitate symptom-based initial diagnosis of rare diseases by clinicians. In this work we aimed at developing a computational approach to aid in that initial diagnosis. We also aimed at implementing this approach in a user friendly web prototype. We call this tool Rare Disease Discovery. Finally, we also aimed at testing the performance of the prototype. Methods. Rare Disease Discovery uses the publicly available ORPHANET data set of association between rare diseases and their symptoms to automatically predict the most likely rare diseases based on a patient’s symptoms. We apply the method to retrospectively diagnose a cohort of 187 rare disease patients with confirmed diagnosis. Subsequently we test the precision, sensitivity, and global performance of the system under different scenarios by running large scale Monte Carlo simulations. All settings account for situations where absent and/or unrelated symptoms are considered in the diagnosis. Results. We find that this expert system has high diagnostic precision (≥80%) and sensitivity (≥99%), and is robust to both absent and unrelated symptoms. Discussion. The Rare Disease Discovery prediction engine appears to provide a fast and robust method for initial assisted differential diagnosis of rare diseases. We coupled this engine with a user-friendly web interface and it can be freely accessed at http://disease-discovery.udl.cat/.

Cardio-oncology is a multidisciplinary field focusing on the management and prevention of cardiovascular complications in cancer patients and survivors. While the initial focus of this specialty was on heart failure associated with anthracycline use, novel anticancer agents are increasingly utilized and are associated with many other cardiotoxicities including hypertension, arrhythmias and vascular disease. Since its inception, the field has developed at a rapid pace with the establishment of programs at many major academic institutions and community practices. Given the complexities of this patient population, it is important for providers to possess knowledge of not only cardiovascular disease but also cancer subtypes and their specific therapeutics. Developing a cardio-oncology program at a stand-alone cancer center can present unique opportunities and challenges when compared to those affiliated with other institutions including resource allocation, cardiovascular testing availability and provider education. In this review, we present our experiences establishing the cardio-oncology program at Moffitt Cancer Center and provide guidance to those individuals interested in developing a program at a similar independent cancer institution.

Large deformation image classification using generalized locality-constrained linear coding.

2013-01-01

Magnetic resonance (MR) imaging has been demonstrated to be very useful for clinical diagnosis of Alzheimer's disease (AD). A common approach to using MR images for AD detection is to spatially normalize the images by non-rigid image registration, and then perform statistical analysis on the resulting deformation fields. Due to the high nonlinearity of the deformation field, recent studies suggest to use initial momentum instead as it lies in a linear space and fully encodes the deformation field. In this paper we explore the use of initial momentum for image classification by focusing on the problem of AD detection. Experiments on the public ADNI dataset show that the initial momentum, together with a simple sparse coding technique-locality-constrained linear coding (LLC)--can achieve a classification accuracy that is comparable to or even better than the state of the art. We also show that the performance of LLC can be greatly improved by introducing proper weights to the codebook.

Parental experiences with a hospital-based bead programme for children with congenital heart disease.

To present survey findings on parental experiences with a hospital-based bead programme for children with congenital heart disease. The Heart Beads programme commenced at a paediatric hospital in Australia in 2008. Children enrolled in the programme are awarded a distinctive bead for every procedure/treatment they have while in hospital. A previous evaluation study on the programme revealed that the beads are therapeutic for the child and parents; however, due to a small sample size, the results were representative of the experiences of a small number of families who participated in the programme. This was an evaluation study which employed a nonexperimental descriptive design. Surveys were mailed to all eligible families who enrolled in the programme. Data collection occurred between July-December 2012. Questions on parental experiences with the Heart Beads programme were divided into three categories: understanding, acknowledgement and quality. Descriptive statistics were obtained and analysed. One hundred and sixty-two mothers and 136 fathers responded to the survey. Heart Beads assisted mothers (83%) and fathers (80%) with understanding their child's condition and helped them with communication (mothers 80%, fathers 58%). The majority of fathers felt that their experience was acknowledged by nursing staff (64%) and medical staff (62%), while mothers indicated a higher response from nurses (76%) compared to medical staff (67%). Overall, parents rated the programme positively; however, there was some concern that children at times missed out on beads. Understanding how mothers and fathers experience the programme differently can guide staff in their communication with parents and inform future initiatives. The Heart Beads help nurses understand how parents are experiencing care and ways in which they can provide support and acknowledgement of the parent's experience. © 2014 John Wiley & Sons Ltd.

2017-04-11

Children and families living with rare disease often experience significant health, psychosocial, economic burdens and diagnostic delays. Experiences appear to be constant, regardless of the specific rare disease diagnosis. Systematically collected Australian data to support policy response on rare diseases are scarce. We address this gap by providing survey results about 462 children aged <19 years living with approximately 200 different rare diseases. Of 462 children, 96% were born in Australia, 55% were male, median age was 8.9 years (0-18.2). Four-hundred-and-twenty-eight (93%) had received a definitive diagnosis but 29 (7%) remained undiagnosed. Before receiving the correct diagnosis 38% consulted ≥ 6 different doctors. Among those with a diagnosis, 37% believed the diagnosis was delayed and 27% initially received a wrong diagnosis. Consequences of delayed diagnosis include anxiety, loss of reproductive confidence because of an ill-defined genetic risk, frustration and stress (54%), disease progression (37%), delays in treatment (25%) and inappropriate treatments (10%). Perceived reasons for diagnostic delays included lack of knowledge about the disease among health professionals (69.2%), lack of symptom awareness by the family (21.2%) and difficulties accessing tests (17.9%). Children with inborn errors of metabolism were less likely to have a delayed diagnosis compared with other disease groups (Chi-Sq = 17.1; P < 0.0001), most likely due to well-established and accessible biochemical screening processes. Diagnosis was given in person in 74% of cases, telephone in 18.5% and via a letter in 3.5%. Some families (16%) were dissatisfied with the way the diagnosis was delivered, citing lack of empathy and lack of information from health professionals. Psychological support at diagnosis was provided to 47.5%, but 86.2% believed that it should always be provided. Although 74.9% of parents believed that the diagnosis could have an impact on future family planning, only 44.8% received genetic counselling. Parents of children living with rare chronic and complex diseases have called for better education, resourcing of health professionals to prevent avoidable diagnostic delays, and to facilitate access to early interventions and treatments. Access to psychological support and genetic counselling should be available to all parents receiving a life-changing diagnosis for their child.

Barriers to palliative care in people with chronic obstructive pulmonary disease in home care: A qualitative study of the perspective of professional caregivers.

2018-02-01

To examine the experiences with palliative care in people with chronic obstructive pulmonary disease among professional caregivers in a Danish home care setting. Many patients with advanced chronic obstructive pulmonary disease depend on professional caregivers in the primary sector to provide assistance and care. However, chronic obstructive pulmonary disease patients receive no or only very little palliative care compared to patients with cancer although they may have many burdensome symptoms. Qualitative explorative study. In 2013-2014, ten professional caregivers from three districts in a Danish municipality were followed during home visits to patients with chronic obstructive pulmonary disease and individual interviews about palliative care were subsequently conducted. In 2014, 66 professional caregivers, representing eleven home care districts, participated in ten group discussions about palliative care needs in this group of patients. Data were analysed using qualitative descriptive analysis. The study revealed a nonawareness of palliative care for patients with chronic obstructive pulmonary disease among the professional caregivers who expressed vague understanding of palliative care and lack of knowledge about the disease. Organisational barriers, such as lack of time and continuity in patient care, lack of opportunity to discuss palliative care and lack of peer learning were experienced as challenging in the provision of palliative care. Nonawareness and organisational barriers led to difficulties in identifying palliative care needs and reluctance to initiate conversations about palliative care. The findings indicate a need for education, training and reflection among professional caregivers in home care. Also, organisational changes may be needed to reduce the barriers to palliative care. The findings uncovered barriers to palliative care that must be addressed. Targeted educational programmes and organisational changes may increase the ability to identify palliative care needs and initiate and evaluate palliative interventions. © 2017 John Wiley & Sons Ltd.

Most publications to date compare outcomes after post-surgical thyroid remnant ablation stimulated by recombinant human thyrotropin (rhTSH) versus thyroid hormone withholding/withdrawal (THW) in low-recurrence risk differentiated thyroid carcinoma (DTC) patients. We sought to perform this comparison in high-risk patients. We retrospectively analyzed ~9-year single-center experience in 70 consecutive adults with initial UICC (Union for International Cancer Control) stage III/IV, M0 DTC undergoing rhTSH-aided (N.=54) or THW-aided (N.=16) high-activity ablation. Endpoints included ablation success and DTC outcome. Assessed ≥1 year post-ablation, ablation success comprised a) no visible scintigraphic thyroid bed uptake or pathological extra-thyroidal uptake; b) undetectable stimulated serum thyroglobulin (Tg) without interfering autoantibodies; c) both criteria. DTC outcome, determined at the latest visit, comprised either 1) "no evidence of disease" (NED): undetectable Tg, negative Tg autoantibodies, negative most recent whole-body scan, no suspicious findings clinically, on neck ultrasonography, or on other imaging; 2) persistent disease: failure to attain NED; or 3) recurrence: loss of NED. After the first ablative activity, ablation success by scintigraphic plus biochemical criteria was 64.8% in rhTSH patients, 56.3% in THW patients (P=NS). After 3.5-year versus 6.2-year median follow-up (P<0.05), DTC outcomes were NED, 85.2%, persistent disease, 13.0%, recurrence, 1.9%, in the rhTSH group and NED, 87.5%, persistent or recurrent disease, 6.3% each, in the THW group (P=NS). In patients with initial stage III/IV, M0 DTC, rhTSH-aided and THW-assisted ablation were associated with comparable remnant eradication or DTC cure rates.

Risk factors and cognitive sequelae of brain arteriolosclerosis pathology are not fully understood. To address this, we used multimodal data from the National Alzheimer's Coordinating Center and Alzheimer's Disease Neuroimaging Initiative data sets. Previous studies showed evidence of distinct neurodegenerative disease outcomes and clinical-pathological correlations in the “oldest-old” compared to younger cohorts. Therefore, using the National Alzheimer's Coordinating Center data set, we analyzed clinical and neuropathological data from two groups according to ages at death: < 80 years (n = 1008) and ≥80 years (n = 1382). In both age groups, severe brain arteriolosclerosis was associated with worse performances on global cognition tests. Hypertension (but not diabetes) was a brain arteriolosclerosis risk factor in the younger group. In the ≥ 80 years age at death group, an ABCC9 gene variant (rs704180), previously associated with aging-related hippocampal sclerosis, was also associated with brain arteriolosclerosis. A post-hoc arterial spin labeling neuroimaging experiment indicated that ABCC9 genotype is associated with cerebral blood flow impairment; in a convenience sample from Alzheimer's Disease Neuroimaging Initiative (n = 15, homozygous individuals), non-risk genotype carriers showed higher global cerebral blood flow compared to risk genotype carriers. We conclude that brain arteriolosclerosis is associated with altered cognitive status and a novel vascular genetic risk factor. PMID:26738751

In the general population, prostate adenocarcinoma affects predominately older men. If fact, most current guidelines suggest that males over the age of 50 years should undergo prostate cancer screening. However, the clinical behavior and prognosis of prostate cancer in young adults is not well defined. The aim of this study was to evaluate the clinical behavior, pathological characteristics, and prognosis of prostate cancer in young adults. We retrospectively reviewed the records of young patients (age, ≤50 years) in our hospital with prostate adenocarcinoma between 1997 and 2013. We compared data including initial presentation, cancer cell type, Gleason score, disease stage, prostate-specific antigen (PSA) level, prostate volume, treatment, and survival between patients both younger and older than 50 years. Data were analyzed using the Kaplan-Meier method to assess survival. Twenty-six patients were enrolled in our study, accounting for 0.55% of all patients with a diagnosis of prostate cancer at our facility. All 26 patients had a pathology diagnosis of adenocarcinoma, with a mean age on diagnosis of 46.8±2.8 years (range, 39-50 years). On initial presentation, patients older than 50 years more frequently displayed lower urinary tract symptoms (LUTS) than younger patients (62.3% vs. 30.4%, p=0.008). There was no statistical difference in histological grade, disease stage, PSA level, overall survival, and biochemical-free survival between the two groups. The result of our investigation indicated that prostate adenocarcinoma patients younger than 50 years had similar histological grade, disease stage, PSA level, overall survival, and biochemical-free survival as the older population. However, patients younger than 50 years with prostate cancer less frequently showed initial symptoms of LUTS. Copyright © 2016. Published by Elsevier Taiwan LLC.

In 2012, a European initiative called S ingle Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is possibly its most devastating extra-articular manifestation. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment practices differ widely, within and between nations. To provide recommendations for the diagnosis and treatment of JIA-associated uveitis. Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of nine experienced paediatric rheumatologists and three experts in ophthalmology from Europe. Recommendations derived from a validated systematic literature review were evaluated by an Expert Committee and subsequently discussed at two consensus meetings using nominal group techniques. Recommendations were accepted if >80% agreement was reached (including all three ophthalmologists). In total, 22 recommendations were accepted (with >80% agreement among experts): 3 on diagnosis, 5 on disease activity measurements, 12 on treatment and 2 on future recommendations. The SHARE initiative aims to identify best practices for treatment of patients suffering from JIA-associated uveitis. Within this remit, recommendations for the diagnosis and treatment of JIA-associated uveitis have been formulated by an evidence-informed consensus process to suggest a standard of care for JIA-associated uveitis patients throughout Europe. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2014-01-01

Salivary gland diseases in children are rare, apart from viral-induced diseases. Nevertheless, it is essential for the otolaryngologist to recognize these uncommon findings in children and adolescents and to diagnose and initiate the proper treatment. The present work provides an overview of the entire spectrum of congenital and acquired diseases of the salivary glands in childhood and adolescence. The current literature was reviewed and the results discussed and summarized. Besides congenital diseases of the salivary glands in children, the main etiologies of viral and bacterial infections, autoimmune diseases and tumors of the salivary glands were considered. In addition to the known facts, new developments in diagnostics, imaging and therapy, including sialendoscopy in obstructive diseases and chronic recurrent juvenile sialadenitis were taken into account. In addition, systemic causes of salivary gland swelling and the treatment of sialorrhoea were discussed. Although salivary gland diseases in children are usually included in the pathology of the adult, they differ in their incidence and some­times in their symptoms. Clinical diagnostics and especially the surgical treatment are influenced by a stringent indications and a less invasive strategy. Due to the rarity of tumors of the salivary glands in children, it is recommended to treat them in a specialized center with greater surgical experience. Altogether the knowledge of the differential diagnoses in salivary gland diseases in children is important for otolaryngologists, to indicate the proper therapeutic approach. PMID:25587366

Understanding the time-dependent changes of biomarkers related to Alzheimer’s disease (AD) is a key to assessing disease progression and to measuring the outcomes of disease-modifying therapies. In this paper, we validate an Alzheimer’s disease progression score model which uses multiple biomarkers to quantify the AD progression of subjects following three assumptions: (1) there is a unique disease progression for all subjects, (2) each subject has a different age of onset and rate of progression, and (3) each biomarker is sigmoidal as a function of disease progression. Fitting the parameters of this model is a challenging problem which we approach using an alternating least squares optimization algorithm. In order to validate this optimization scheme under realistic conditions, we use the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort. With the help of Monte Carlo simulations, we show that most of the global parameters of the model are tightly estimated, thus enabling an ordering of the biomarkers that fit the model well, ordered as: the Rey auditory verbal learning test with 30 minutes delay, the sum of the two lateral hippocampal volumes divided by the intra-cranial volume, followed by (the clinical dementia rating sum of boxes score and the mini mental state examination score) in no particular order and lastly the Alzheimer’s disease assessment scale-cognitive subscale.

Pre-existing central nervous system lesions negate cytokine requirements for regional experimental autoimmune encephalomyelitis development.

PubMed

Li, Xin; Lees, Jason R

2013-03-01

In region-specific forms of experimental autoimmune encephalomyelitis (EAE), lesion initiation is regulated by T-cell-produced interferon-γ (IFN-γ) resulting in spinal cord disease in the presence of IFN-γ and cerebellar disease in the absence of IFN-γ. Although this role for IFN-γ in regional disease initiation is well defined, little is known about the consequences of previous tissue inflammation on subsequent regional disease, information vital to the development of therapeutics in established disease states. This study addressed the hypothesis that previous establishment of regional EAE would determine subsequent tissue localization of new T-cell invasion and associated symptoms regardless of the presence or absence of IFN-γ production. Serial transfer of optimal or suboptimal doses of encephalitogenic IFN-γ-sufficient or -deficient T-cell lines was used to examine the development of new clinical responses associated with the spinal cord and cerebellum at various times after EAE initiation. Previous inflammation within either cerebellum or spinal cord allowed subsequent T-cell driven inflammation within that tissue regardless of IFN-γ presence. Further, T-cell IFN-γ production after initial lesion formation exacerbated disease within the cerebellum, suggesting that IFN-γ plays different roles at different stages of cerebellar disease. For the spinal cord, IFN-γ-deficient cells (that are ordinarily cerebellum disease initiators) were capable of driving new spinal-cord-associated clinical symptoms more than 60 days after the initial acute EAE resolution. These data suggest that previous inflammation modulates the molecular requirements for new neuroinflammation development. © 2012 Blackwell Publishing Ltd.

Conflicts at work are associated with a higher risk of cardiovascular disease.

Jacob, Louis; Kostev, Karel

2017-01-01

Background: Only few authors have analyzed the impact of workplace conflicts and the resulting stress on the risk of developing cardiovascular disorders. The goal of this study was to analyze the association between workplace conflicts and cardiovascular disorders in patients treated by German general practitioners. Methods: Patients with an initial documentation of a workplace conflict experience between 2005 and 2014 were identified in 699 general practitioner practices (index date). We included only those who were between the ages of 18 and 65 years, had a follow-up time of at least 180 days after the index date, and had not been diagnosed with angina pectoris, myocardial infarction, coronary heart diseases, or stroke prior to the documentation of the workplace mobbing. In total, the study population consisted of 7,374 patients who experienced conflicts and 7,374 controls for analysis. The main outcome measure was the incidence of angina pectoris, myocardial infarction, and stroke correlated with workplace conflict experiences. Results: After a maximum of five years of follow-up, 2.9% of individuals who experienced workplace conflict were affected by cardiovascular diseases, while only 1.4% were affected in the control group (p-value <0.001). Workplace conflict was associated with a 1.63-fold increase in the risk of developing cardiovascular diseases. Finally, the impact of workplace conflict was higher for myocardial infarction (OR=2.03) than for angina pectoris (OR=1.79) and stroke (OR=1.56). Conclusions: Overall, we found a significant association between workplace conflicts and cardiovascular disorders.

Much of the common practice in paediatric mechanical ventilation is based on personal experiences and what paediatric critical care practitioners have adopted from adult and neonatal experience. This presents a barrier to planning and interpretation of clinical trials on the use of specific and targeted interventions. We aim to establish a European consensus guideline on mechanical ventilation of critically children. The European Society for Paediatric and Neonatal Intensive Care initiated a consensus conference of international European experts in paediatric mechanical ventilation to provide recommendations using the Research and Development/University of California, Los Angeles, appropriateness method. An electronic literature search in PubMed and EMBASE was performed using a combination of medical subject heading terms and text words related to mechanical ventilation and disease-specific terms. The Paediatric Mechanical Ventilation Consensus Conference (PEMVECC) consisted of a panel of 15 experts who developed and voted on 152 recommendations related to the following topics: (1) general recommendations, (2) monitoring, (3) targets of oxygenation and ventilation, (4) supportive measures, (5) weaning and extubation readiness, (6) normal lungs, (7) obstructive diseases, (8) restrictive diseases, (9) mixed diseases, (10) chronically ventilated patients, (11) cardiac patients and (12) lung hypoplasia syndromes. There were 142 (93.4%) recommendations with "strong agreement". The final iteration of the recommendations had none with equipoise or disagreement. These recommendations should help to harmonise the approach to paediatric mechanical ventilation and can be proposed as a standard-of-care applicable in daily clinical practice and clinical research.

An integrative systems biology approach to understanding pulmonary diseases.

Auffray, Charles; Adcock, Ian M; Chung, Kian Fan; Djukanovic, Ratko; Pison, Christophe; Sterk, Peter J

2010-06-01

Chronic inflammatory pulmonary diseases such as COPD and asthma are highly prevalent and associated with a major health burden worldwide. Despite a wealth of biologic and clinical information on normal and pathologic airway structure and function, the primary causes and mechanisms of disease remain to a large extent unknown, preventing the development of more efficient diagnosis and treatment. We propose to overcome these limitations through an integrative systems biology research strategy designed to identify the functional and regulatory pathways that play central roles in respiratory pathophysiology, starting with severe asthma. This approach relies on global genome, transcriptome, proteome, and metabolome data sets collected in cross-sectional patient cohorts with high-throughput measurement platforms and integrated with biologic and clinical data to inform predictive multiscale models ranging from the molecular to the organ levels. Working hypotheses formulated on the mechanisms and pathways involved in various disease states are tested through perturbation experiments using model simulation combined with targeted and global technologies in cellular and animal models. The responses observed are compared with those predicted by the initial models, which are refined to account better for the results. Novel perturbation experiments are designed and tested both computationally and experimentally to arbitrate between competing hypotheses. The process is iterated until the derived knowledge allows a better classification and subphenotyping of severe asthma using complex biomarkers, which will facilitate the development of novel diagnostic and therapeutic interventions targeting multiple components of the molecular and cellular pathways involved. This can be tested and validated in prospective clinical trials.

Autoimmune diabetes recurrence should be routinely monitored after pancreas transplantation.

PubMed

Martins, La Salete

2014-09-24

Autoimmune type 1 diabetes recurrence in pancreas grafts was first described 30 years ago, but it is not yet completely understood. In fact, the number of transplants affected and possibly lost due to this disease may be falsely low. There may be insufficient awareness to this entity by clinicians, leading to underdiagnosis. Some authors estimate that half of the immunological losses in pancreas transplantation are due to autoimmunity. Pancreas biopsy is the gold standard for the definitive diagnosis. However, as an invasive procedure, it is not the ideal approach to screen the disease. Pancreatic autoantibodies which may be detected early before graft dysfunction, when searched for, are probably the best initial tool to establish the diagnosis. The purpose of this review is to revisit the autoimmune aspects of type 1 diabetes and to analyse data about the identified autoantibodies, as serological markers of the disease. Therapeutic strategies used to control the disease, though with unsatisfactory results, are also addressed. In addition, the author's own experience with the prospective monitoring of pancreatic autoantibodies after transplantation and its correlation with graft outcome will be discussed.

Finding models to detect Alzheimer's disease by fusing structural and neuropsychological information

NASA Astrophysics Data System (ADS)

Giraldo, Diana L.; García-Arteaga, Juan D.; Velasco, Nelson; Romero, Eduardo

2015-12-01

Alzheimer's disease (AD) is a neurodegenerative disease that affects higher brain functions. Initial diagnosis of AD is based on the patient's clinical history and a battery of neuropsychological tests. The accuracy of the diagnosis is highly dependent on the examiner's skills and on the evolution of a variable clinical frame. This work presents an automatic strategy that learns probabilistic brain models for different stages of the disease, reducing the complexity, parameter adjustment and computational costs. The proposed method starts by setting a probabilistic class description using the information stored in the neuropsychological test, followed by constructing the different structural class models using membership values from the learned probabilistic functions. These models are then used as a reference frame for the classification problem: a new case is assigned to a particular class simply by projecting to the different models. The validation was performed using a leave-one-out cross-validation, two classes were used: Normal Control (NC) subjects and patients diagnosed with mild AD. In this experiment it is possible to achieve a sensibility and specificity of 80% and 79% respectively.

Persistent effects of chlorine inhalation on respiratory health

PubMed Central

Hoyle, Gary W.; Svendsen, Erik R.

2016-01-01

Chlorine gas is a toxic respiratory irritant that is considered a chemical threat agent because of the potential for release in industrial accidents or terrorist attacks. Chlorine inhalation damages the respiratory tract, including the airways and distal lung, and can result in acute lung injury. Some individuals exposed to chlorine experience a full recovery from acute injury, whereas others develop persistent adverse effects, such as respiratory symptoms, inflammation, and lung-function decrements. In animal models, chlorine can produce persistent inflammation, remodeling, and obstruction in large or small airways, depending on species. Airways with pseudostratified epithelium are repaired efficiently, with surviving basal epithelial cells serving as progenitor cells that repopulate the complement of differentiated cell types. Distal airways lacking basal cells are repaired less efficiently, leading to chronic inflammation and fibrosis at these sites. Persistent chlorine-induced airway disease in humans is treated with asthma medication to relieve symptoms. However, such treatment does not ameliorate the underlying disease pathogenesis, so treatments that are more effective at preventing initial development of airway disease after irritant gas exposure and at reversing established disease are needed.

This article reviews the pathophysiology of scleroderma (systemic sclerosis [SSc]) and its destructive effects on the mandible in general and the temporomandibular joint (TMJ) in particular. It discusses the considerations of operating on patients with devastating chronic disease and presents 2 cases of TMJ reconstruction in patients with the diagnosis. Two patients with different degrees of SSc involvement underwent TMJ reconstruction with costochondral grafts. The patients represent the surgical considerations pertinent to this disease and different outcomes as determined by the variance in severity of their afflictions. The 2 patients tolerated the surgeries well and exhibited improvement in function in the long-term. One patient thrives and continues to do well despite her SSc approximately 10 years postoperatively; the second patient died of her disease approximately 9 years after her initial surgical care. The experience with these 2 cases showed that patients with SSc can safely undergo TMJ reconstruction with anticipated good results, but that the overall severity of the disease remains paramount in determining the feasibility of corrective surgery under this diagnosis.

The bioresorbable vascular scaffold (BRS) technology constitutes the new revolution of the coronary artery disease interventional treatment. Currently, three distinct types of BRSs are available but only one, the Absorb BVS, was on the market in 2013 when the Regional Commission for Medical Devices and the Cardiology and Cardiac Surgery Commission of the Emilia-Romagna Region drew up a technical and scientific essay to provide guidance for the introduction of BRS in public and affiliated health facilities. Five preferential indications were given for use: long coronary lesions (>28 mm), ostial lesions (left main stem excluded), complete revascularization in patients aged <50 years, diffuse disease (>40 mm) or involving the mid/distal left anterior descending (LAD) branch in patients <70 years, spontaneous coronary artery dissection. This survey analyzed data from all the catheterization laboratories in the Emilia-Romagna Region, merged in a unified database. In a 3-year study period, 546 BRS were implanted in 328 patients, corresponding to 1.5% of the drug-eluting stents (DES) used, with a trend towards a progressive increase over time. Initial indications were followed in 200/328 (61.0%) patients (about one third fitting more indications), mainly for treatment of long lesions in vessels >2.5 mm (67%), young patients (31.5%) and mid/distal LAD (28%). In 22.6% of cases the clinical scenario was a ST-segment elevation myocardial infarction, in 39.3% a non-ST-segment elevation acute coronary syndrome. Intracoronary imaging was infrequently used (intravascular ultrasound in 24.7% of cases). In 85 patients (25.9%) a hybrid procedure (BVS/DES) was performed. BRS use has resulted lower than expected, with discrete variability among centers, but according to the initial indications of the Emilia-Romagna Region in the majority of cases. The underuse might have been due to operators' caution in their initial experience. However, the increasing trend may reveal a greater confidence in the implantation technique and the whole amount of safety and efficacy data.

Family physicians' experiences when collaborating with district nurses in home care-based medical treatment. A grounded theory study.

This article concerns Swedish family physicians' (FPs) experiences collaborating with district nurses (DNs) when the DNs provide medical treatment for home care patients. The aim was to develop a model to illuminate this process from the FPs' perspective. Semi-structured interviews were conducted with 13 FPs concerning one of their patients with home care by a DN. The interview focused on one patient's treatment and care by different care providers and the collaboration among them. Grounded theory methodology (GTM) was used in the analyses. It was essential for FPs to collaborate with and rely on DNs in the medical treatment of home care patients. According to the FPs, factors such as the disease, FPs' working conditions and attitude determined how much of the initiative in this treatment FPs retained or left to DNs. Depending on the circumstances, two different roles were adopted by the individual FPs: medical conductors who retain the initiative and medical consultants who leave the initiative to DNs. Factors as the disease, DNs' attitudes towards collaboration and DNs' working conditions influenced whether or not the FPs felt that grounds for relying on DNs were satisfactory. Regardless of the role of the FP, conditions for medical treatment were judged by the FPs to be good enough when the grounds for relying on the DN were satisfactory and problematic when they were not. In the role of conductor, the FP will identify when the grounds for relying on the DN are unsatisfactory and be able to take action, but in the role of consultant the FP will not detect this, leaving home care patients without appropriate support. Only when there are satisfactory grounds for relying on the DN, will conditions for providing home care medical treatment be good enough when the FP adopts a consultative role.

Rapid immunochromatographic diagnosis and Rolling Back Malaria--experiences from an African control program.

Malaria is a re-emerging disease in much of Africa. In response, the World Health Organization launched the Roll Back Malaria (RBM) initiative. One of six key principles adopted is the early detection of malaria cases. However, the importance of definitive diagnosis and potential value of field deployment of rapid malaria tests in RBM has been largely ignored. The Lowveld Region of Mpumalanga Province, South Africa, is home to a predominantly non-immune population, of approximately 850000 inhabitants, who are at risk of seasonal Plasmodium falciparum malaria. Malaria treatment in this area is usually only initiated on detection of malaria parasites in the peripheral bloodstream, as many other rickettsial and viral febrile illness mimic malaria. The malaria control programme traditionally relied on light microscopy of Giemsa-stained thick blood films for malaria diagnosis. This review summarizes operational research findings that led to the introduction of rapid malaria card tests for primary diagnosis of malaria throughout the Mpumalanga malaria area. Subsequent operational research and extensive experience over a four-year period since introducing the ICT Malaria Pf test appears to confirm the local appropriateness of this diagnostic modality. A laboratory is not required and clinic staff are empowered to make a prompt definitive diagnosis, limiting delays in initiating correct therapy. The simple, accurate and rapid non-microscopic means now available for diagnosing malaria could play an important role in Rolling Back Malaria in selected areas.

Serogroup B outer membrane vesicles (OMV) with iron regulated proteins (IRP) from Neisseria meningitidis constitute the antigen for the vaccine against the disease caused by this bacterium. Aiming to enhance final OMV concentration, seven batch experiments were carried out under four different conditions: (i) with original Catlin medium; (ii) with original Catlin medium and lactate and amino acids pulse at the 6th cultivation hour; (iii) with Catlin medium with double initial concentrations of lactate and amino acids and (iv) Catlin medium without glycerol and with double initial concentrations of lactate and amino acids. The cultivation experiments were carried out in a 7-L bioreactor under the following conditions: 36°C, 0.5atm, overlay air 1L/min, agitation: 250-850 rpm, and O(2) control at 10%, 20 h. After lactate and amino acids exhaustion, cell growth reached stationary phase and a significant release increase of OMV was observed. According to the Luedeking & Piret model, OMV liberation is non-growth associated. Glycerol was not consumed during cultivation. The maximum OMV concentration value attained was 162 mg/L with correspondent productivity of 8.1mg/(Lh) employing Catlin medium with double initial concentrations of lactate and amino acids. The obtained OMV satisfied constitution and protein pattern criteria and were suitable for vaccine production. Copyright © 2012 Elsevier Ltd. All rights reserved.

To explore the experiences of patients with advanced Chronic Obstructive Pulmonary Disease (COPD) and lung cancer, their carers and healthcare professionals following emergency admission to acute care hospital. Emergency admissions of people with lung cancer and COPD have increased and there is global concern about the number of patients who die in hospital. The experience of patients with advanced lung cancer and COPD admitted to hospital as an emergency when nearing the end of life has not previously been investigated. Qualitative critical incident case study. Semistructured interviews were conducted with 39 patients (15 with COPD and 24 with lung cancer), 20 informal carers and 50 healthcare professionals, exploring patients' experiences of emergency hospital admission. Interviews took place after admission and following discharge. Participants nominated relatives and healthcare professionals for interview. Data were analysed thematically. Patients were satisfied with their 'emergency' care but not the care they received once their initial symptoms had been stabilised. The poorer quality care they experienced was characterised by a lack of attention to their fundamental needs, lack of involvement of the family, poor communication about care plans and a lack of continuity between primary and secondary care. A conceptual model of 'spectacular' and 'subtacular' trajectories of care was used to relate the findings to the wider context of health care provision. The complex nature of illness for patients with advanced respiratory disease makes emergency hospital admissions likely. Whilst patients (with COPD and lung cancer) were satisfied with care in the acute 'spectacular' phase of their admission, more attention needs to be given to the continuing care needs of patients in the 'subtacular' phase. This is the first study to explore the patient experience of acute care following an emergency admission and identifies where there is potential for care to be improved. © 2016 John Wiley & Sons Ltd.

The Gluten-Free Diet in the 3rd Millennium: Rules, Risks and Opportunities

PubMed Central

Welstead, Lori

2015-01-01

The gluten-free diet has long been considered the standard treatment for celiac disease. However, a significant number of patients continue to experience persistent symptoms despite following a gluten-free diet. Inadvertent gluten ingestion, fermentable carbohydrates, cross-contamination, and social or financial burdens present obstacles to maintaining a gluten-free diet. Proper diet education and follow-up by an expert Registered Dietitian (RD) is essential to ensure adequate nutrition on the gluten-free diet. Patients may experience unintended weight gain or elevated cholesterol levels after initiating the gluten-free diet due to adequate absorption and healing of the intestines. This review deals with the evolving gluten-free diet, optimal recommendations while considering the overall health of patients, and multi-factorial aspects of the permanent lifestyle change.

Considerations for Community-Based mHealth Initiatives: Insights From Three Beacon Communities

PubMed Central

2013-01-01

Mobile health (mHealth) is gaining widespread attention for its potential to engage patients in their health and health care in their daily lives. Emerging evidence suggests that mHealth interventions can be used effectively to support behavior change, but numerous challenges remain when implementing these programs at the community level. This paper provides an overview of considerations when implementing community-based mHealth initiatives, based on the experiences of three Beacon Communities across the United States that have launched text messaging (short message service, SMS) pilot programs aimed at diabetes risk reduction and disease management. The paper addresses lessons learned and suggests strategies to overcome challenges related to developing text message content, conducting marketing and outreach, enrolling participants, engaging providers, evaluating program effectiveness, and sustaining and scaling the programs.

In 2012, the French Infectious Diseases Society (French acronym SPILF) initiated the "Coordination of epidemic and biological risk" (SPILF-COREB - Emergences [SCE]) group to support the readiness and response of healthcare workers (HCWs) to new alerts. To present the SCE group, its functioning, and the main support it provided for frontline HCWs. A multidisciplinary group of heads of infectious disease departments from reference hospitals was created to build a network of clinical expertise for care, training, and research in the field of epidemic and biological risk (EBR). The network developed a set of standardized operational procedures (SOPs) to guide interventions to manage EBR-suspect patients. A working group created the SOP aimed at frontline HCWs taking care of patients. Priority was given to the development of a generic procedure, which was then adapted according to the current alert. Five key steps were identified and hierarchized: detecting, protecting, caring for, alerting, and referring the EBR patient. The interaction between clinicians and those responsible for the protection of the community was crucial. The SOPs validated by the SPILF and its affiliates were disseminated to a wide range of key stakeholders through various media including workshops and the SPILF's website. SPILF can easily adapt and timely mobilize the EBR expertise in case of an alert. The present work suggests that sharing and discussing this experience, initiated at the European level, can generate a new collective expertise and needs to be further developed and strengthened.

Public opinion and professional organisations dominate the euthanasia debate, and there is a need to understand the opinions of people confronted with euthanasia. The aim of this study was to investigate whether patients and their GPs talk about euthanasia, and if so, how they communicate about this. Qualitative, semi-structured interviews were held with 20 GPs and 30 of their patients in primary care in the Netherlands, where euthanasia is legalised. The patients had a life expectancy of less than 6 months, and cancer, heart failure or chronic obstructive pulmonary disease as underlying disease. Many patients did not communicate about euthanasia with their GP. Neither the patient nor the GP were clear in formulating their expectations concerning future decision making. The initial patient-GP communication consisted of an exchange of opinions about situations in which euthanasia would be desirable. GPs had different opinions about who should initiate communication, and found it difficult to judge the right moment to talk. It is essential to pay attention to education in communication about dying and euthanasia and to train the GPs to gain insight in the patient's end-of-life preferences, and to direct care at the best possible quality of life.

Legg-Calvé-Perthes disease (LCPD) is a significant problem in healthcare because it so commonly affects young adults and immature athletes, primarily gymnasts. In this paper, a two-degree-of-freedom (2-DOF) hip exoskeleton device was developed for study on an immature animal model of exercise-induced LCPD. The exoskeleton device can reproduce the repetitive actions and forceful centrality impingements on the coxafemoral head that occur in sports such as gymnastics and acrobatics. It initiated a new method rather than the traditional medical or physiological operation method to establish an animal model of LCPD and allowed for the development and testing of new treatments. Ten immature New Zealand white rabbits were selected for the experiment. Their right legs were driven to achieve repetitive extension/ flexion and abduction/adduction beyond the normal range of motion, with centrality impingements at the maximum flexion position, while their left legs were kept in the initial healthy status and acted as the comparing reference. Four weeks later, the basic symptoms of early LCPD of the femoral head appeared. The results of X-ray, magnetic resonance imaging (MRI), gross anatomy observation, and H-E section also revealed it.

Parkinson's disease (PD) is a neurodegenerative disease that affects the motor system and cognitive and behavioral functions. Due to these impairments, PD patients also have problems in using the computer. However, using computers and the Internet could help these patients to overcome social isolation and enhance information search. Specifically, avatars (defined as virtual representations of humans) are increasingly used in online environments to enhance human-computer interaction by simulating face-to-face interaction. Our laboratory experiment investigated how PD patients behave in a trust game played with human and avatar counterparts, and we compared this behavior to the behavior of age, income, education and gender matched healthy controls. The results of our study show that PD patients trust avatar faces significantly more than human faces. Moreover, there was no significant difference between initial trust of PD patients and healthy controls in avatar faces, while PD patients trusted human faces significantly less than healthy controls. Our data suggests that PD patients' interaction with avatars may constitute an effective way of communication in situations in which trust is required (e.g., a physician recommends intake of medication). We discuss the implications of these results for several areas of human-computer interaction and neurological research.

Background Initiation of antiretroviral therapy (ART) in the advanced stages of HIV infection remains a major challenge in sub-Saharan Africa. This study was conducted to better understand barriers and enablers to timely ART initiation in Rwanda where ART coverage is high and national ART eligibility guidelines first expanded in 2007–2008. Methods Using data on 6326 patients (≥15 years) at five Rwandan clinics, we assessed trends and correlates of CD4+ cell count at ART initiation and the proportion initiating ART with advanced HIV disease (CD4+ <200 cells/µl or WHO stage IV). Results Out of 6326 patients, 4486 enrolling in HIV care initiated ART with median CD4+ cell count of 211 cells/µl [interquartile range: 131–300]. Median CD4+ cell counts at ART initiation increased from 183 cells/µl in 2007 to 293 cells/µl in 2011–2012, and the proportion with advanced HIV disease decreased from 66.2 to 29.4%. Factors associated with a higher odds of advanced HIV disease at ART initiation were male sex [adjusted odds ratios (AOR) = 1.7; 95% confidence interval (CI): 1.3–2.1] and older age (AOR46–55+ vs. <25 = 2.3; 95% CI: 1.2–4.3). Among those initiating ART more than 1 year after enrollment in care, those who had a gap in care of 12 or more months prior to ART initiation had higher odds of advanced HIV disease (AOR = 5.2; 95% CI: 1.2–21.1). Conclusion Marked improvements in the median CD4+ cell count at ART initiation and proportion initiating ART with advanced HIV disease were observed following the expansion of ART eligibility criteria in Rwanda. However, sex disparities in late treatment initiation persisted through 2011–2012, and appeared to be driven by later diagnosis and/or delayed linkage to care among men. PMID:25562492

The new generation of expandable plastic esophageal stents (Polyflex; Boston Scientific, Natick, MA), combine the features of plastic and self-expanding metallic stents. The main objective of this study is to evaluate our initial experience with Polyflex expandable stents in the treatment of esophageal disease from two institutions. A total of 58 Polyflex stents were placed in 38 patients over a two-year period. There were 24 men and 14 women, with a median age of 63 years (range, 25 to 83). The most common indication for placement was an esophageal stricture in 25 patients (66%); other causes included leak in 8 (21%) and tracheoesophageal fistula (TEF) in 5 (13%). We evaluated the hospital course, complications, and outcomes. The median postoperative stay was one day. Complications included migration in 38 stents (63%) (28 patients; 73%), retrosternal chest discomfort in nine, reflux in four, airway obstruction in one, and food impaction in three. Continued leak or a persistent TEF occurred in five patients (38%). Reintervention was required predominantly due to migration of the stent at a mean interval of 46 days (range, 1 to 353). Patients with dysphagia improved significantly with dysphagia scores (1 = no dysphagia; 5 = unable to swallow saliva) improving from 3.44 to 2.15 (p < 0.0001). Polyflex stents were effective in the relief of dysphagia due to strictures. They were less effective in esophageal perforations or leaks. Their primary disadvantage is a high migration rate and further improvements in design are required to decrease this high incidence of migration.

Patient refusal of and nonadherence to treatment with disease-modifying antirheumatic drugs (DMARDs) can adversely affect disease outcomes in rheumatoid arthritis (RA). This qualitative study describes how RA patients' feelings in response to experiences and information affected their decisions to accept (agree to adopt, initiate, and implement) or resist (refuse, avoid, and discontinue) DMARD treatment regimens. A total of 48 RA patients were interviewed about their experiences making decisions about DMARDs. The interviews were transcribed, coded, and analyzed for themes related to their internal motivations for accepting or resisting treatment regimens, using a narrative analysis approach. In addition to feelings about the necessity and dangers of medications, patients' feelings towards their identity as an ill person, the act of taking medication, and the decision process itself were important drivers of patient's decisions. For patients' motivations to accept treatment regimens, 2 themes emerged: a desire to return to a normal life, and fear of future disability due to RA. For motivations to resist treatment regimens, 5 themes emerged: fear of medications, maintaining control over health, denial of sick identity, disappointment with treatment, and feeling overwhelmed by the cognitive burden of deciding. Feelings in response to experiences and information played a major role in how patients weighed the benefits and costs of treatment options, suggesting that addressing patients' feelings may be important when rheumatologists counsel about therapeutic options. Further research is needed to learn how best to address patients' feelings throughout the treatment decision-making process. © 2017, American College of Rheumatology.

To explore the illness experiences of older patients with late-stage chronic obstructive pulmonary disease and to develop knowledge about how patients perceive their preferences to be taken into account in decision-making processes concerning mechanical ventilation and/or noninvasive ventilation. Decisions about whether older patients with late-stage chronic obstructive pulmonary disease will benefit from noninvasive ventilation treatment or whether the time has come for palliative treatment are complicated, both medically and ethically. Knowledge regarding patients' values and preferences concerning ventilation support is crucial yet often lacking. Qualitative design with a hermeneutic-phenomenological approach. The data consist of qualitative in-depth interviews with 12 patients from Norway diagnosed with late-stage chronic obstructive pulmonary disease. The data were analysed within the three interpretative contexts described by Kvale and Brinkmann. The participants described their lives as fragile and burdensome, frequently interrupted by unpredictable and frightening exacerbations. They lacked information about their diagnosis and prognosis and were often not included in decisions about noninvasive ventilation or mechanical ventilation. Findings indicate that these patients are highly vulnerable and have complex needs in terms of nursing care and medical treatment. Moreover, they need access to proactive advanced care planning and an opportunity to discuss their wishes for treatment and care. To provide competent care for these patients, healthcare personnel must be aware of how patients experience being seriously ill. Advanced care planning and shared decision-making should be initiated alongside the curative treatment. © 2017 John Wiley & Sons Ltd.

Rubella in Israel after the MMR vaccine: elimination or containment?

Since 1996, after the full institution of the two-dose measles, mumps, and rubella vaccine (MMR) regimen in Israel, rubella incidence has declined dramatically and has remained extremely low. Cyclical outbreaks ended; the two brief outbreaks that did occur were quickly contained; and epidemiological data indicate that the disease is practically absent from the country. But similar steep declines in the incidence of measles and mumps, the two other MMR-preventable diseases, were followed by major outbreaks in 2007 and 2010. Epidemiological analyses show that undervaccination of subgroups within the Jewish ultra-orthodox population, both in Israel and abroad, and virus importation into Israel, continue to be risk factors for all three MMR-preventable diseases. Israel's public health system, therefore, should focus on a policy of containment: improve MMR coverage among undervaccinated subgroups and assure that virus importation is no longer a risk. Then the goal of rubella elimination will become feasible. We discuss how the Israeli experience may contribute to the World Health Organization Initiative to eliminate simultaneously measles and rubella.

Aspirin (ASA) is the mainstay of treatment in cerebrovascular and systemic vascular disease. ASA hypersensitivity can pose a challenge to achieving optimum medical management prior to and after neurointerventional treatment. Desensitization to ASA is well described in the allergy and cardiovascular literature, but there are no similar discussions specific to neurointervention. The purpose of our study was to describe our experience with ASA hypersensitivity management and review the relevant literature. Two cases of patients with symptomatic cerebrovascular disease requiring neurointervention who were successfully desensitized to their ASA hypersensitivity prior to treatment are described. The subsequent literature is reviewed. Several ASA desensitization protocols exist and have been proven to successfully treat ASA hypersensitivity and allow for ASA therapy to be safely initiated. We describe several previously published protocols. ASA desensitization is a safe and simple way to manage ASA hypersensitivity. We provide comprehensive management guidelines for the neurointerventionalist engaging in ASA desensitization.

Chronic kidney disease stage 5 is a global health challenge in the context of population ageing across the world. The range of treatment options available to patients at all ages has increased and includes transplantation and dialysis. However, these options are often seen as inappropriate for older frailer patients who are now offered the option of conservative kidney management, which is presented as a non-invasive alternative to dialysis, involving symptom management and addressing psychosocial needs. In this study, we conducted qualitative interviews with 26 close persons caring for someone with chronic kidney disease stage 5 in the United Kingdom to investigate how conservative kidney management interacted with implicit ideas of ageing, in both the experience of conservative kidney management and the understanding of the prognosis and future care of the kidney disease. Our findings highlighted participant confusion about the nature of conservative kidney management, which stems from an initial lack of clarity about how conservative kidney management differed from conventional treatments for chronic kidney disease stage 5. In particular, some respondents were not aware of the implicit palliative nature of the intervention or indeed the inevitable end-of-life issues. Although these findings can be situated within the context of communication failure, we would further argue that they also bring to the surface tensions in the discourses surrounding ageing and old age, drawing on the use of a ‘natural’ and a ‘normal’ paradigm of ageing. In the context of chronic kidney disease stage 5, more patients are being dialysed at older ages, but conservative kidney management is being advanced as a better option than dialysis in terms of quality of life and experience. However, in doing so, conservative kidney management implicitly draws on a notion of older age that echoes natural ageing rather than advocate a more interventionist approach. The role of discourses of ageing in the provision of treatments for conservative kidney management has not previously been acknowledged, and this article addresses this gap. PMID:24695386

Little data in the literature exist concerning patients with certain underlying medical conditions who receive allergen subcutaneous immunotherapy (SCIT). To survey allergists' experience with SCIT in patients with medical conditions considered to impose an elevated risk for untoward outcomes. A Web-based survey was conducted among members of the American Academy of Allergy, Asthma & Immunology to query about their experience with SCIT in patients with certain medical conditions. There were 1085 replies (21% response), of whom, 86% were U.S. based, 51% were suburban, 31% were academic, 42% were medium-sized practices, and 54% had >15 years' experience. In responders' opinion, SCIT was "contraindicated" in patients with the following: acquired immune deficiency syndrome (AIDS) (48%), cancer (and still receiving active treatment) (33%), severe asthma (32%), and a history of transplantation (30%). Even so, survey responders collectively gave SCIT to >2400 patients for each of these conditions: severe asthma, coronary artery disease, cancer in remission, and autoimmune disorders; and to ≥5400 patients with hypertension and ≥4100 women who became pregnant. The experience of colleagues with these patients rarely resulted in major problems (i.e., activation of underlying disease, systemic reactions to SCIT, or SCIT discontinuation), with the exception of severe asthma (12.5%), initiation of SCIT during pregnancy (5.4%), and AIDS (4.2%). For most other conditions, it was ≤1.5% (e.g., continue during pregnancy, cancer in remission, history of transplantation, positive human immunodeficiency virus and no AIDS). According to the experience of a large group of practicing allergists, the American Academy of Allergy, Asthma & Immunology members, few medical conditions seemed to pose an elevated risk for untoward outcomes from SCIT. Because these are survey results, prospective research might yield even more solid data.

Patients in randomized clinical trials have to adapt themselves to a restricted language to capture the necessary information to determine the safety and efficacy of a new treatment. The aim of this study was to explore the experience of patients with rheumatoid arthritis after completing their participation in a biologic therapy randomized clinical trial for a period of 3 years. A qualitative approach was used. The information was collected using 15 semi-structured interviews of patients with rheumatoid arthritis. Data collection was guided by the emergent analysis until no more relevant variations in the categories were found. The data were analysed using the grounded theory method. The objective of the patients when entering the study was to improve their quality of life by initiating the treatment. However, the experience changed the significance of the illness as they acquired skills and practical knowledge related to the management of their disease. The category "Interactional Empowerment" emerged as core category, as it represented the participative experience in a clinical trial. The process integrates the follow categories: "weight of systematisation", "working together", and the significance of the experience: "the duties". Simultaneously these categories evolved. The clinical trial monitoring activities enabled patients to engage in a reflexive-interpretative mechanism that transformed the emotional and symbolic significance of their disease and improved the empowerment of the patient. A better communicative strategy with the health professionals, the relatives of the patients, and the community was also achieved.

Simple Summary First initiated in 1995 to provide veterinary students with spay/neuter experience, the shelter program at the Mississippi State University College of Veterinary Medicine has grown to be comprehensive in nature incorporating spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Junior veterinary students spend five days in shelters; senior veterinary students spend 2-weeks visiting shelters in mobile veterinary units. The program has three primary components: spay/neuter, shelter medical days and Animals in Focus. Student gain significant hands-on experience and evaluations of the program by students are overwhelmingly positive. Abstract The shelter program at the Mississippi State University College of Veterinary Medicine provides veterinary students with extensive experience in shelter animal care including spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Students spend five days at shelters in the junior year of the curriculum and two weeks working on mobile veterinary units in their senior year. The program helps meet accreditation standards of the American Veterinary Medical Association’s Council on Education that require students to have hands-on experience and is in keeping with recommendations from the North American Veterinary Medical Education Consortium. The program responds, in part, to the challenge from the Pew Study on Future Directions for Veterinary Medicine that argued that veterinary students do not graduate with the level of knowledge and skills that is commensurate with the number of years of professional education.

Monitoring prevalence of advanced human immunodeficiency virus (HIV) disease (i.e., CD4+ T-cell count <200 cells/μL) among persons starting antiretroviral therapy (ART) is important to understand ART program outcomes, inform HIV prevention strategy, and forecast need for adjunctive therapies.* , † , § To assess trends in prevalence of advanced disease at ART initiation in 10 high-burden countries during 2004-2015, records of 694,138 ART enrollees aged ≥15 years from 797 ART facilities were analyzed. Availability of national electronic medical record systems allowed up-to-date evaluation of trends in Haiti (2004-2015), Mozambique (2004-2014), and Namibia (2004-2012), where prevalence of advanced disease at ART initiation declined from 75% to 34% (p<0.001), 73% to 37% (p<0.001), and 80% to 41% (p<0.001), respectively. Significant declines in prevalence of advanced disease during 2004-2011 were observed in Nigeria, Swaziland, Uganda, Vietnam, and Zimbabwe. The encouraging declines in prevalence of advanced disease at ART enrollment are likely due to scale-up of testing and treatment services and ART-eligibility guidelines encouraging earlier ART initiation. However, in 2015, approximately a third of new ART patients still initiated ART with advanced HIV disease. To reduce prevalence of advanced disease at ART initiation, adoption of World Health Organization (WHO)-recommended "treat-all" guidelines and strategies to facilitate earlier HIV testing and treatment are needed to reduce HIV-related mortality and HIV incidence.

Renal lymphoma is an uncommon renal tumor in children. Unlike renal lymphomas presenting as bilateral disease and renal failure, we report a boy who presented with unilateral renal involvement. After initial nephrectomy, he achieved remission with multiagent chemotherapy but relapsed systemically within 3 months. He was initiated on salvage chemotherapy with autologous bone marrow transplant. Even though the initial manifestation was localized lymphoma eventually, it turned out to be a systemic disease. He succumbed to disease at 14 months from diagnosis.

Statistical analysis on arbitrary surface meshes such as the cortical surface is an important approach to understanding brain diseases such as Alzheimer’s disease (AD). Surface analysis may be able to identify specific cortical patterns that relate to certain disease characteristics or exhibit differences between groups. Our goal in this paper is to make group analysis of signals on surfaces more sensitive. To do this, we derive multi-scale shape descriptors that characterize the signal around each mesh vertex, i.e., its local context, at varying levels of resolution. In order to define such a shape descriptor, we make use of recent results from harmonic analysis that extend traditional continuous wavelet theory from the Euclidean to a non-Euclidean setting (i.e., a graph, mesh or network). Using this descriptor, we conduct experiments on two different datasets, the Alzheimer’s Disease NeuroImaging Initiative (ADNI) data and images acquired at the Wisconsin Alzheimer’s Disease Research Center (W-ADRC), focusing on individuals labeled as having Alzheimer’s disease (AD), mild cognitive impairment (MCI) and healthy controls. In particular, we contrast traditional univariate methods with our multi-resolution approach which show increased sensitivity and improved statistical power to detect a group-level effects. We also provide an open source implementation. PMID:24614060

Evidence of reducing ethanol content in beverages to reduce harmful use of alcohol.

Alcohol use is a major contributor to the burden of gastrointestinal disease. WHO's global strategy to reduce harmful use of alcohol encourages the alcohol industry to contribute to this effort. However, evidence that alcohol producers have contributed to the reduction of harmful use of alcohol is scarce. Reduction of alcoholic strength of beer has been proposed and initiated as one potential way forward. We examine the evidence base for the success of such an initiative. Direct evidence from natural experiments or other controlled studies is scarce. We identified three potential mechanisms for how reduction of alcoholic strength could affect harmful use of alcohol: by current drinkers replacing standard alcoholic beverages with similar beverages of lower alcoholic strength, without increasing the quantity of liquid consumed; by current drinkers switching to no alcohol alternatives for part of the time, thereby reducing their average amount of ethanol consumed; and by initiating alcohol use in current abstainers. The first mechanism seems to be the most promising to potentially reduce harm, but much will depend on actual implementation, and only an independent assessment will be able to identify effects on harmful drinking. The potential of alcoholic strength reduction is independent of initiation by law or by self-initiative of the industry. Copyright © 2016 Elsevier Ltd. All rights reserved.

A reliable liver autoimmune serology for the diagnosis of primary biliary cholangitis (PBC) is of particular importance. Recognition of patients at early stages and prompt treatment initiation may alter the outcome, slow progression, delays liver failure, and improves survival. In this review, we summarize and discuss the published data obtained from literature searches from PubMed and The National Library of Medicine (USA) and our own experience on the current and potential molecular based approaches to the diagnosis of PBC. Expert commentary: Standardization of liver diagnostic serology and clinical governance are two major points as antimitochondrial antibodies are the diagnostic hallmark of the disease and PBC-specific antinuclear antibodies could assist in the diagnosis and estimation of prognosis. New biomarkers such as novel autoantibodies, genetic polymorphisms, metabolomic profiling, micro-RNA and epigenetics may assist to the understanding, diagnosis and management of the disease.

We have analyzed all patients with HP-negative gastric MALT lymphoma undergoing antibiotic therapy as sole management of their disease. HP negativity was defined as negative histology, breath test and serology, and response to treatment, survival and long-term outcome was assessed together with clinico-pathological characteristics including t(11; 18) (q21; q21) translocation. Out of 97 patients with gastric MALT lymphoma, 24 were HP-negative, and 13 (5 females and 8 males) underwent only antibiotic management for initial therapy. Eight had stage I and five were found to have stage II disease, with three patients suffering from an underlying autoimmune disease. Antibiotic therapy consisted of standard HP eradication regimens consisting of clarithromycin in all patients, along with metronidazole in seven and amoxicillin in six plus a proton-pump inhibitor. After a median follow-up of 95 months (42-, 181+), 12/13 patients are alive. Six patients with stage I disease achieved an objective response (five complete (CR) and one partial remission, 46 %), four had stable disease (lasting 11-27 months), and three progressed. All patients with stable disease received chemotherapy, but only one patient due to clear cut progression. One patient relapsed 23 months after initial CR, and achieved a second CR with antibiotics now lasting 87 months. These results indicate that a relevant percentage of patients with HP-negative gastric MALT lymphoma may benefit from antibiotic therapy and do not require additional oncological therapies. Our data suggest that the remissions seen in these patients might be durable as evidenced by prolonged follow-up in our series.

To provide preliminary clinical data regarding endoscopically placed nitinol stents for children with tracheal obstruction as a temporizing measure to allow for trach tube decannulation while awaiting growth to allow for tracheal resection. This case series describes the experiences of two children (ages 5 and 15) who were dependent upon tracheotomy because of acquired tracheal obstruction. Both patients had combined tracheomalacia and tracheal stenosis. After failing tracheoplasty with rib graft augmentation both patients suffered from extensive tracheal disease, which was too long to allow for immediate tracheal resection. Endoscopic placement of nitinol stents in the obstructed tracheal segment using fluoroscopic guidance. All tracheotomy tubes were removed immediately after successful stent deployment with the patient still under general anesthesia. Four stents were placed in total. The first patient's initial stent was too narrow and was, therefore, removed and replaced at a later date with a larger diameter stent. The second patient experienced distal migration of his initial stent requiring stent removal and replacement at a later date. Both patients remain successfully decannulated (follow-up, 25 and 26 months) and are currently living more normal lives as they grow and await tracheal resection. Preliminary use of nitinol stents for pediatric tracheal obstruction has enabled successful decannulation in two children with complicated airways. Our results with this series of patients suggest that nitinol stents can be safely used in children as a temporizing measure until tracheal resection can be safely performed. With this approach children can live free from the hassles of trach care, social isolation and peer ridicule. Limited pediatric experience exists in the literature about nitinol stents. Thus, our experience with stent selection and placement will help others avoid problems encountered in this initial series. Copyright 2002 Elsevier Science Ireland Ltd.

The effects of fasting and refeeding on biochemical parameters in the red-legged partridge (Alectoris rufa).

Every year, about three million farm-reared red-legged partridges are released in Spain for hunting purposes, most of them for restocking where the success is very low. Some factors such as the sudden shift from abundant commercial energy-rich diet to natural food and absence of experience at looking for natural food resources could cause a rapid physical deterioration, being more vulnerable to predation and disease. To determine fasting capacity in red-legged partridges, we fasted 32 birds during 4 days and then we refed them, collecting blood samples and body masses during the experiment. Red-legged partridges entered in the third critic phase of fasting, in which body proteins became the main energetic source, after 48 h of fasting. The fasting period caused an average loss of 17% of their initial body mass and only attained a 93.6% of their initial body mass after 24 days of refeeding. The limited capacity to resist fasting in the red-legged partridge could be one of the reasons for the low success in restocking, mainly in those where neither supplementary feeding nor acclimation period is allowed for birds before they are finally released.

In spite of the healthy immigrant effect, the prevalence of lifestyle-related chronic diseases among migrants is reported to approximate that of the host country with longer duration of stay. For example, higher rates of chronic diseases such as Type 2 diabetes and hypertension have been observed among Filipino migrants and these have been linked to acculturation. The aim of this study was to explore the experiences of Filipino-Australian migrants in managing their chronic health conditions in a Western host country. This paper reports on qualitative findings of a mixed methods study that used an explanatory sequential design. Nine focus group discussions were undertaken with 58 Filipino-Australian migrants with chronic disease. Thematic analysis was undertaken using a five-stage general purpose thematic framework ensuring that themes closely identified key participants' experiences . Findings revealed that health benefits provided by the health system in Australia were considered advantageous. However, a lack of social and instrumental support compounded isolation and disempowerment, limiting self-management strategies for chronic illnesses. Cultural beliefs and practices influenced their knowledge, attitude to and management of chronic disease, which health service providers overlooked because of perceived acculturation and English language skills. Overall this study has clearly identified recognition of cultural beliefs, language needs and support as three core needs of Filipino-Australian migrants with the elderly the most vulnerable. This paper highlights that self-management of chronic disease among elderly Filipino immigrants may be adversely affected by host language difficulties, a lack of social support and cultural issues, impacting on access to services, health-seeking behaviours and participation in health promotion initiatives. Language, culture-specific health interventions and resources and enhancing social support are likely important strategies in promoting chronic disease self-management among the elderly. These interventions have the potential to empower and encourage individuals to take control and better manage their chronic disease.

Clear cell sarcoma of the tendons and aponeuroses (CCSTA) is an aggressive, rare soft-tissue tumor with approximately 300 reported cases. Although it appears to be histogenetically related to melanoma, its clinical behavior resembles soft tissue sarcoma with a propensity for lymph node metastases. We report our experience at a tertiary cancer center. Eight cases of CCSTA evaluated at Roswell Park Cancer Institute between 1970 and 1998 were reviewed retrospectively. Patient data analyzed included patient age, gender, anatomic location, size of tumor, development of local, regional and distant recurrence, and patient status at last follow up. Six of eight patients were alive at 2 years, while three of seven patients were alive at 5 years. Of the patients alive with no evidence of recurrence, two had tumors of less than 2 cm, and the remaining patient had incomplete information regarding tumor size. Five patients recurred within 2 years of definitive surgical management. Four had tumors > 5 cm. All five patients progressed to metastatic disease at a median follow up of 20 months (range 1-108 months) following definitive surgical management and all eventually died of their disease at a median of 3 months (range 0-24 months) from presentation with metastatic disease. Four of five patients with lesions > 5 cm received adjuvant chemotherapy with intent to cure, but all eventually died of disease at 4, 22, 34, and 41 months from initial presentation. CCSTA is an aggressive tumor of the soft tissues. Early recognition and management are associated with an excellent long-term prognosis. Tumors greater than 5 cm warrant aggressive surgical management and treatment, and are at high risk of the development of distant disease. Aggressive multiagent chemotherapy appeared to have no impact on outcome. Other adjuvant therapeutic options including immunotherapy should be investigated. Copyright 2001 Wiley-Liss, Inc.

Men and women with rheumatic diseases report a significantly negative impact on multiple areas of life, including sexuality. Research indicates that patients want to discuss sexual issues with health professionals (HPs) in rheumatology care but these issues are rarely addressed in consultations. The objective of the present study was to explore patients' experiences of communication with HPs about disease-related sexual issues, their perceptions of the relevance of these issues in rheumatology care and their preferences for how these topics should be handled. A qualitative design was used and 18 semi-structured interviews were performed, including eight women and ten men with inflammatory rheumatic joint diseases, aged 29-62 years. The interviews were recorded and transcribed verbatim. Data were analysed thematically. Four main themes were derived from the interviews: (i) relevance of sexual issues; (ii) vital conditions for communication; (iii) individual preferences in mode and timing of information and communication; and (iv) benefits of information and communication. The participants expressed that, although sexual issues are relevant, necessary conditions for good communication are largely lacking. HPs' knowledge, experience and personal skills, as well as having sufficient time were essential. HPs lack of initiating sexual topics contributed to uncertainty about whether their sexual challenges were disease related and whether it was a legitimate topic to discuss in rheumatology care. Patients wanted HPs to possess knowledge about possible disease-related challenges in sexual life and intimate relationships, and to facilitate communication about these aspects. There is a need to develop practice guidelines to enable HPs to integrate sexual issues as an aspect of healthcare delivery in a patient-friendly manner. Copyright © 2016 John Wiley & Sons, Ltd.

Coronary artery disease is highly prevalent in patients with stroke, but because revascularization does not improve major clinical outcomes in patients with stable coronary artery disease relative to intensive medical therapy, routine evaluation for this disease is not warranted in stroke patients. However, it might be warranted in patients destined to undergo vigorous physical therapy. The Locomotor Experience Applied Post-Stroke study, a randomized controlled trial of 408 participants that tested the relative efficacy of two rehabilitation techniques on functional walking level, provided the opportunity to address this question. The study aims to test the efficacy of screening for cardiovascular disease and an exercise tolerance test in assuring safety among patients undergoing vigorous rehabilitation for gait impairment. All participants were screened for serious cardiovascular and pulmonary conditions. At six-weeks poststroke, they also completed a cardiovascular screening inventory and underwent an exercise tolerance test involving bicycle ergometry. Participants received 36, 90-min sessions of a prescribed physical therapy (three per week), initiated at either two-months or six-months poststroke. Twenty-nine participants were excluded on the basis of the cardiac screening questionnaire, and 15 failed the exercise tolerance test for cardiovascular reasons. No participant experienced a cardiac event during a treatment session. Two participants experienced myocardial infarctions, but continued in the trial. In three additional participants, myocardial infarctions caused or contributed to death. The combination of a negative cardiac screen and the absence of exercise tolerance test failure appeared to have a high negative predictive value for cardiac events during treatment, despite the likelihood of a high prevalence of coronary artery disease in our population. © 2014 World Stroke Organization.

We analyze the experience of the Center of General Surgery and Liver Transplantation from the Fundeni Clinical Institute (Bucharest, Romania) regarding orthotopic liver transplantation (OLT) in adult recipients, with whole liver grafts from cadaveric donors, between April 2000 (when the first successful LT was performed in Romania) and December 2004. This series includes 37 OLTs in adult recipients (16 women and 21 men, aged between 29-57 years--average 46 years). Other two LT with whole liver cadaveric grafts and two reduced-size LT were performed in children; also, in the same period, due to the acute organ shortage, other methods of LT were performed in 28 patients (21 living donor LT, 6 split LT and one "do mino" LT), that were not included in the present series. The indications for OLT were HBV cirrhosis--10, HBV+HDV cirrhosis--4, HCV cirrhosis--11, HBV+HCV cirrhosis--2, biliary cirrhosis--5, Wilson disease--2, alcoholic cirrhosis--1, non-alcoholic liver disease--1, autoimmune cirrhosis--1. With three exceptions, in which the classical transplantation technique was used, the liver was grafted following the technique described by Belghiti. Local postoperative complications occurred in 15 patients (41%) and general complications in 17 (46%); late complications were registered in 18 patients (49%) and recurrence of the initial disease in 6 patients (16%). Intrao- and postoperative mortality was 8% (3/37). There were two patients (5%) who died because of immunosuppressive drug neurotoxicity at more than 30 days following LT. Four patients (11%) died lately because of PTLD, liver venoocclusive disease, recurrent autoimmune hepatitis and liver venoocclusive disease, myocardial infarction, respectively. Thirty-four patients survived the postoperative period (92%); according to Kaplan-Meier analysis, actuarial patient-survival rate at month 31 was 75%.

The Argentinean program was initiated more than a decade ago as the first experience of systematic translational research focused on NCL in Latin America. The aim was to overcome misdiagnoses and underdiagnoses in the region. 216 NCL suspected individuals from 8 different countries and their direct family members. Clinical assessment, enzyme testing, electron microscopy, and DNA screening. 1) The study confirmed NCL disease in 122 subjects. Phenotypic studies comprised epileptic seizures and movement disorders, ophthalmology, neurophysiology, image analysis, rating scales, enzyme testing, and electron microscopy, carried out under a consensus algorithm; 2) DNA screening and validation of mutations in genes PPT1 (CLN1), TPP1 (CLN2), CLN3, CLN5, CLN6, MFSD8 (CLN7), and CLN8: characterization of variant types, novel/known mutations and polymorphisms; 3) Progress of the epidemiological picture in Latin America; and 4) NCL-like pathology studies in progress. The Translational Research Program was highly efficient in addressing the misdiagnosis/underdiagnosis in the NCL disorders. The study of "orphan diseases" in a public administrated hospital should be adopted by the health systems, as it positively impacts upon the family's quality of life, the collection of epidemiological data, and triggers research advances.

Considerations on BVD eradication for the Irish livestock industry

PubMed Central

2011-01-01

Animal Health Ireland has produced clear guidelines for the control of Bovine Viral Diarrhoea (BVD) infection in Irish cattle herds. In the course of developing these guidelines it was clear that a framework for regional and/or national BVD control would be required to increase the uptake of BVD control at farm level and reduce the overall prevalence of the disease. This paper assessed the economic impact of BVD, epidemiological aspects of the disease to its control, models of BVD control, international experiences of BVD control programmes. The technical knowledge and test technology exists to eradicate BVD. Indeed, many countries have successfully and others are embarking on control of the disease. The identification and prompt elimination of PI cattle will form the basis of any control programme. The trade of such animals must be curtailed. Pregnant and potentially pregnant carrying PI foetuses pose a significant threat. International experience indicates systematic, well coordinated programmes have the most success, while voluntary programmes can make good initial progress but ultimately fail. The farming community must buy into any proposed programme, and without their support, failure is likely. To buy into the programme and create such a demand for BVD control, farmers must first be well informed. It is likely that stemming economic loss and improving productivity will be the primary motivator at individual farm level. PMID:21967764

Effects of auditory cues on gait initiation and turning in patients with Parkinson's disease.

To review the available scientific evidence about the effectiveness of auditory cues during gait initiation and turning in patients with Parkinson's disease. We conducted a literature search in the following databases: Brain, PubMed, Medline, CINAHL, Scopus, Science Direct, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Library Plus, CENTRAL, Trip Database, PEDro, DARE, OTseeker, and Google Scholar. We included all studies published between 2007 and 2016 and evaluating the influence of auditory cues on independent gait initiation and turning in patients with Parkinson's disease. The methodological quality of the studies was assessed with the Jadad scale. We included 13 studies, all of which had a low methodological quality (Jadad scale score≤2). In these studies, high-intensity, high-frequency auditory cues had a positive impact on gait initiation and turning. More specifically, they 1) improved spatiotemporal and kinematic parameters; 2) decreased freezing, turning duration, and falls; and 3) increased gait initiation speed, muscle activation, and gait speed and cadence in patients with Parkinson's disease. We need studies of better methodological quality to establish the Parkinson's disease stage in which auditory cues are most beneficial, as well as to determine the most effective type and frequency of the auditory cue during gait initiation and turning in patients with Parkinson's disease.

Several robot-assisted radical prostatectomy (RARP) series have reviewed the impact of the initial learning curve on perioperative outcomes. However, little is known about the impact of experience on urinary and sexual outcomes. Herein, we review the perioperative, pathological and functional outcomes of our initial 700 consecutive procedures with at least 1 year follow up. From 2003-2006, 700 consecutive men underwent RARP at a single, academic institution. Perioperative data and pathologic outcomes were prospectively collected. Validated, UCLA-PCI-SF36v2 quality-of-life questionnaires were also obtained at 1, 3, 6 and 12 months following surgery. Outcomes between groups (cases 1-300, 301-500, and 501-700) were compared.

Linden, Peter K

2009-01-01

Solid organ transplantation is one of the most remarkable and dramatic therapeutic advances in medicine during the past 60 years. This field has progressed initially from what can accurately be termed a "clinical experiment" to routine and reliable practice, which has proven to be clinically effective, life-saving and cost-effective. This remarkable evolution stems from a serial confluence of: cultural acceptance; legal and political evolution to facilitate organ donation, procurement and allocation; technical and cognitive advances in organ preservation, surgery, immunology, immunosuppression; and management of infectious diseases. Some of the major milestones of this multidisciplinary clinical science are reviewed in this article.

Alzheimer's disease and other neurological disorders.

Henderson, V W

Menopausal status and estrogen-containing hormone therapy may influence several neurological disorders, including Alzheimer's disease, epilepsy, migraine headache, multiple sclerosis, Parkinson's disease, sleep disorders, and stroke. For most of these illnesses, evidence on hormone therapy is insufficient to guide practice decisions. For stroke, clinical trial evidence indicates that hormone therapy increases risk of cerebral infarction. For women with Alzheimer's disease, estrogen treatment trials have tended to be small and of short duration. Most suggest that estrogen started after the onset of dementia symptoms does not meaningfully improve cognition or slow disease progression. Hormone therapy initiated after age 64 increased all-cause dementia in the Women's Health Initiative Memory Study. Many observational studies, however, report protective associations between hormone use and Alzheimer risk. Apparent risk reduction may represent a bias toward hormone therapy, since hormones are more often prescribed to healthier women. However, when compared to the Women's Health Initiative Memory Study, estrogen exposures in many observational studies reflect hormone initiation at a younger age, closer to the time of menopause. One intriguing hypothesis is that hormone therapy initiated or used during an early critical window may reduce later Alzheimer incidence. Public health implications of this hypothesis are important, but current data are inadequate to decide the issue.

Fabry nephropathy: a review - how can we optimize the management of Fabry nephropathy?

PubMed

Waldek, Stephen; Feriozzi, Sandro

2014-05-06

Fabry disease is a rare, X-linked, lysosomal storage disease caused by mutations in the gene encoding the enzyme alpha-galactosidase A. Complete or partial deficiency in this enzyme leads to intracellular accumulation of globotriaosylceramide (Gb3) and related glycosphingolipids in many cell types throughout the body, including the kidney. Progressive accumulation of Gb3 in podocytes, epithelial cells and the tubular cells of the distal tubule and loop of Henle contribute to the renal symptoms of Fabry disease, which manifest as proteinuria and reduced glomerular filtration rate leading to chronic kidney disease and progression to end-stage renal disease. Early diagnosis and timely initiation of treatment of Fabry renal disease is an important facet of disease management. Initiating treatment with enzyme replacement therapy (ERT; agalsidase alfa, Replagal®, Shire; agalsidase beta, Fabrazyme®, Genzyme) as part of a comprehensive strategy to prevent complications of the disease, may be beneficial in stabilizing renal function or slowing its decline. Early initiation of ERT may also be more effective than initiating therapy in patients with more advanced disease. Several strategies are required to complement the use of ERT and treat the myriad of associated symptoms and organ involvements. In particular, patients with renal Fabry disease are at risk of cardiovascular events, such as high blood pressure, cardiac arrhythmias and stroke. This review discusses the management of renal involvement in Fabry disease, including diagnosis, treatments, and follow-up, and explores recent advances in the use of biomarkers to assist with diagnosis, monitoring disease progression and response to treatment.

Patterns and Timing of Failure for Diffuse Large B-Cell Lymphoma After Initial Therapy in a Cohort Who Underwent Autologous Bone Marrow Transplantation for Relapse

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

Dhakal, Sughosh; Bates, James E.; Casulo, Carla

Purpose: To evaluate the location and timing of initial recurrence in patients with diffuse large B-cell lymphoma (DLBCL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplant (HDC/ASCT), to direct approaches for disease surveillance, elucidate the patterns of failure of contemporary treatment strategies, and guide adjuvant treatment decisions. Methods and Materials: We analyzed consecutive patients with DLBCL who underwent HDC/ASCT between May 1992 and March 2014 at our institution. Of the 187 evaluable patients, 8 had incomplete data, and 79 underwent HDC/ASCT as a component of initial treatment for de novo or refractory DLBCL and were excluded from furthermore » analysis. Results: The median age was 50.8 years; the median time to relapse was 1.3 years. Patients were segregated according to the initial stage at diagnosis, with early stage (ES) defined as stage I/II and advanced stage (AS) defined as stage III/IV. In total, 40.4% of the ES and 75.5% of the AS patients relapsed in sites of initial disease; 68.4% of those with ES disease and 75.0% of those with AS disease relapsed in sites of initial disease only. Extranodal relapses were common (44.7% in ES and 35.9% in AS) and occurred in a variety of organs, although gastrointestinal tract/liver (n=12) was most frequent. Conclusions: Most patients with DLBCL who relapse and subsequently undergo HDC/ASCT initially recur in the previously involved disease site(s). Time to recurrence is brief, suggesting that frequency of screening is most justifiably greatest in the early posttherapy years. © 2016 Elsevier Inc.« less

Using the life course perspective to study the entry into the illness trajectory: The perspective of caregivers of people with Alzheimer’s disease

The research community is showing increasing interest in the analysis of the care trajectory of people with chronic health problems, especially dementias such as Alzheimer’s disease. However, despite this interest, there is little research on the initial phases of the care trajectory. The fact that the first symptoms of dementia are generally noticed by those surrounding the elderly person suggests that the recognition of the disease is intimately linked to interactions not only amongst family members but also amongst friends, neighbours and health professionals. This study focuses on the period beginning with the first manifestations of cognitive difficulties and ending with the diagnosis of Alzheimer-type dementia. Interviews with 60 caregivers in Montreal, Canada were used to reconstruct how older people with Alzheimer-type dementia enter into the care trajectory. Our methods consisted of the analysis of social networks, social dynamics and action sequences. Our findings are presented in the form of a typology comprised of 5 pathways of entries into the care trajectory that are structured around the following four principles of the Life Course Perspective: family history, linked lives, human agency and organisational effects. We believe that analyses of the initial phases of the care trajectory, such as this one, are essential for the application of effective early detection and intervention policies. They are also central to informing future studies that seek to understand the care experience in its entirety. PMID:20207459

The goal of this ongoing comprehensive osteoporosis disease management initiative is to provide the adult primary care physicians' (PCPs) offices with a program enabling them to systematically identify and manage their population for osteoporosis. For over six years, Hill Physicians Medical Group (Hill Physicians) has implemented multiple strategies to develop a best practice for identifying and treating members who were candidates for osteoporosis therapy. Numerous tools were used to support this disease management effort, including: evidence-based clinical practice guidelines, patient education sessions, the Simple Calculated Osteoporosis Risk Estimation (SCORE) questionnaire tool, member specific reports for PCPs, targeted member mailings, office-based Peripheral Instantaneous X-ray Imaging (PIXI) test and counseling, dual x-ray absorptiometry (DEXA) scan guidelines, and web-based Electronic Simple Calculated Osteoporosis Risk Estimation (eSCORE) questionnaire tools. Hill Physicians tabulated results for patients who completed 2649 SCORE tests, screened 978 patients with PIXI tests, and identified 338 osteopenic and 124 osteoporotic patients. The preliminary results of this unique six-year ongoing educational initiative are slow but promising. New physician offices express interest in participating and those offices that have participated in the program continue to screen for osteoporosis. Hill Physicians' message is consistent and is communicated to the physicians repeatedly in different ways in accordance with the principles of educational outreach. Physicians who have conducted the program have positive feedback from their patients and office staff and have begun to communicate their experience to their peers.

Pulmonary fibrosis encompasses a group of lung-scarring disorders that occur owing to known or unknown insults and accounts for significant morbidity and mortality. Despite intense investigation spanning decades, much remains to be learned about the natural history, pathophysiology, and biologic mechanisms of disease. To identify the most pressing research needs in the lung fibrosis community and to provide a roadmap of priorities to investigators, funding agencies, patient advocacy groups, and other interested stakeholders. An ad hoc international working group of the American Thoracic Society with experience in clinical, translational, and bench-based research in fibrotic lung diseases was convened. The group used an iterative consensus process to identify successes and challenges in pulmonary fibrosis research. The group identified five main priority areas in which substantial resources should be invested to advance our understanding and to develop novel therapies for patients with pulmonary fibrosis. These priorities include develop newer models of human lung fibrosis, engage current and new stakeholders to provide sustained funding for the initiatives, create a global infrastructure for storing patient-derived materials, establish collaborative preclinical and clinical research networks in fibrotic lung disease, and create a global lung fibrosis initiative that unites these multifaceted efforts into a single virtual umbrella structure. Despite recent advances in the treatment of some forms of lung fibrosis, many gaps in knowledge about natural history, pathophysiology, and treatment remain. Investment in the research priorities enumerated above will help address these shortcomings and enhance patient care worldwide.

Background In 2012, a European initiative called Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) was launched to optimise and disseminate diagnostic and management regimens in Europe for children and young adults with rheumatic diseases. Juvenile dermatomyositis (JDM) is a rare disease within the group of paediatric rheumatic diseases (PRDs) and can lead to significant morbidity. Evidence-based guidelines are sparse and management is mostly based on physicians' experience. Consequently, treatment regimens differ throughout Europe. Objectives To provide recommendations for diagnosis and treatment of JDM. Methods Recommendations were developed by an evidence-informed consensus process using the European League Against Rheumatism standard operating procedures. A committee was constituted, consisting of 19 experienced paediatric rheumatologists and 2 experts in paediatric exercise physiology and physical therapy, mainly from Europe. Recommendations derived from a validated systematic literature review were evaluated by an online survey and subsequently discussed at two consensus meetings using nominal group technique. Recommendations were accepted if >80% agreement was reached. Results In total, 7 overarching principles, 33 recommendations on diagnosis and 19 recommendations on therapy were accepted with >80% agreement among experts. Topics covered include assessment of skin, muscle and major organ involvement and suggested treatment pathways. Conclusions The SHARE initiative aims to identify best practices for treatment of patients suffering from PRD. Within this remit, recommendations for the diagnosis and treatment of JDM have been formulated by an evidence-informed consensus process to produce a standard of care for patients with JDM throughout Europe.

Despite initial remission, approximately 60-70% of adult and 30% of pediatric patients experience relapse or refractory AML. Studies so far have identified base line gene expression profiles of pathogenic and prognostic significance in AML, however extent of change in gene expression post-initiation of treatment has not been investigated. Exposure of leukemic cells to chemotherapeutic agents such as cytarabine, a mainstay of AML chemotherapy can trigger adaptive response by influencing leukemic cell transcriptome and hence development of resistance or refractory disease. It is however challenging to perform such a study due to lack of availability of specimens post-drug treatment. In this study our primary objective was to identify in vivo cytarabine induced changes in leukemia cell transcriptome and to evaluate their impact on clinical outcome. Our results highlight genes relevant to cytarabine resistance and support the concept of targeting cytarabine-induced genes as a means of improving response. PMID:26366682

Pigmented villonodular synovitis (PVNS) is normally treated by arthroscopic or open surgical excision. We present our initial experience with radiofrequency thermo-ablation (RF ablation) of PVNS located in an inaccessible location in the knee. Review of all patients with histologically proven PVNS treated with RF ablation and with at least 2-year follow-up. Three patients met inclusion criteria and were treated with RF ablation. Two of the patients were treated successfully by one ablation procedure. One of the three patients had a recurrence which was also treated successfully by repeat RF ablation. There were no complications and all patients returned to their previous occupations following RF ablation. In this study we demonstrated the feasibility of performing RF ablation to treat PVNS in relatively inaccessible locations with curative intent. We have also discussed various post-ablation imaging appearances which can confound the assessment for residual/recurrent disease.

Palmodigital fasciectomy remains the gold standard. The initial outcome is, in my experience, far more predictable than either NA or enzyme fasciotomy (EF). It is also a more durable treatment. NA and EF can be conceptualized as similar procedures--one uses a needle and the other an enzyme to weaken a cord sufficient to be able to rupture it and thus straighten a contracted joint. Both are less invasive and the hand is quick to recover. Both procedures are equally initially effective. CHH seems to offer greater durability. Today’s patients are often better educated and seek a specific type of treatment, in particular, effective nonoperative treatment. Pharmaceutical companies now market directly and effectively to patients, and this strategy and Internet use have already resulted in an increase in the number of patients searching for practitioners willing to administer and capable of administering collagenase treatment.

Individuals with disabilities experience a disproportionate rate of chronic disease and are more likely to lead sedentary lifestyles than the general population. Multiple complex factors likely contribute to these disparities, including structural, socioeconomic and attitudinal barriers that impede broad participation of individuals with disabilities in health and wellness promotion programs. Public health initiatives aimed at mitigating these health disparities emphasize improved access to physical activity and sports opportunities. Given its visibility, the Paralympic Movement provides an opportunity to transform how society conceptualizes the relationship of disability to physical fitness. The Paralympics also serve as a catalyst for public health education and program development. Already, public policies and governmental regulations are expanding grassroots sports opportunities for youth and adults with disabilities, thus promoting inclusive opportunities for participation in physical activity.

Mitochondrial dysfunction has correlated with a rise in energy deficiency disorders (EDD). The EDDs include mitochondrial disorders, obesity, metabolic disorders, cardiovascular and neurodegenerative disorders. Many individuals in our communities are at high risk of developing these disorders, yet are unaware of it. Our goal was to increase public awareness of mitochondrial health, whilst providing students with an innovative educational experience. We designed a 'Bioenergetics exhibition' by introducing Arts into traditional STEM (Science, Technology, Engineering & Mathematics) disciplines to create a new STEAM-(Health) initiative. Results indicated ~120,000 guests visited the exhibition, including many school-aged children, teachers and families. Comparative analysis of random first-time vs. repeat visitor surveys demonstrated a statistically significant (8.25% at p-value = 0.006) increase in knowledge of mitochondrial disease and bioenergetics. Our findings clearly support the power of the STEAM-H initiative in creatively communicating the complex science to a broader community.

Insights into the variability of nucleated amyloid polymerization by a minimalistic model of stochastic protein assembly

Self-assembly of proteins into amyloid aggregates is an important biological phenomenon associated with human diseases such as Alzheimer's disease. Amyloid fibrils also have potential applications in nano-engineering of biomaterials. The kinetics of amyloid assembly show an exponential growth phase preceded by a lag phase, variable in duration as seen in bulk experiments and experiments that mimic the small volumes of cells. Here, to investigate the origins and the properties of the observed variability in the lag phase of amyloid assembly currently not accounted for by deterministic nucleation dependent mechanisms, we formulate a new stochastic minimal model that is capable of describing the characteristics of amyloid growth curves despite its simplicity. We then solve the stochastic differential equations of our model and give mathematical proof of a central limit theorem for the sample growth trajectories of the nucleated aggregation process. These results give an asymptotic description for our simple model, from which closed form analytical results capable of describing and predicting the variability of nucleated amyloid assembly were derived. We also demonstrate the application of our results to inform experiments in a conceptually friendly and clear fashion. Our model offers a new perspective and paves the way for a new and efficient approach on extracting vital information regarding the key initial events of amyloid formation.

Extracorporeal membrane oxygenation (ECMO) is a technology that can provide extracorporeal gas exchange to patients with severe pulmonary or cardiac dysfunction. We report on our clinical experience with ECMO in critically ill patients. We performed a retrospective analysis of 23 patients treated with ECMO in a medical intensive care unit in a tertiary referral academic centre. 13 patients were considered immunocompetent and 10 were immunocompromised when extracorporeal membrane oxygenation was started. 16 patients presented with acute respiratory distress syndrome (ARDS), 2 patients had intractable cardiac failure, and 5 patients had combined respiratory and cardiac failure. In 16 patients, a veno-venous bypass was constructed; in 7 patients, the initial bypass was venoarterial. 11 patients survived. In 2 patients technical complications were fatal. Our data indicate that patients with community-acquired pneumonia and no underlying disease will benefit most from this technique. However, long-term survival is possible in immunocompromised patients. Venoarterial bypass can carry a higher risk for technical complications. Increasing experience apparently also reduces the risk of technical complications.

Bone marrow transplant (BMT) is a common treatment option for adolescents with various diseases; however, the aggressive therapy often causes significant side effects that can lead to poor eating. There is little documentation of eating experiences and necessary support needed after the initial BMT hospitalization. This phenomenological study, guided by Martin Heidegger’s philosophical influences, revealed the meaning of adolescents’ eating experiences, eating strategies, and the impact of eating on the adolescents’ quality of life during the first 100 days post-BMT. Individual interviews were conducted at 50 and 100 days post-BMT. Data analysis used the hermeneutic circle and revealed 5 themes. Adolescents discussed the slow return of eating, barriers that affected their eating, personal eating strategies, significance of eating, and feelings regarding eating. Eating issues do not end when a BMT patient is discharged from the hospital, and caregivers need to have a better understanding of the ongoing issues affecting adolescents throughout the BMT recovery phase.

The Converged Experience of Risk and Disease

PubMed Central

Aronowitz, Robert A

2009-01-01

Context: One underappreciated consequence of modern clinical and public health practices is that the experience of being at risk for disease has been converging with the experience of disease itself. This is especially true for certain chronic diseases, in which early diagnosis and aggressive treatment have led to symptom-less and sign-less disease and in which treatments have largely been aimed at altering the disease's future course. Methods: This article reviews the historical scholarship and medical literature pertinent to transformations in the chronic disease and risk experiences. Findings: The experience of chronic disease increasingly resembles or has become indistinguishable from risk because of (1) new clinical interventions that have directly changed the natural history of disease; (2) increased biological, clinical, and epidemiological knowledge about the risk of chronic disease; (3) the recruitment of larger numbers into chronic disease diagnoses via new screening and diagnostic technology and disease definitions; (4) new ways of conceptualizing efficacy; and (5) intense diagnostic testing and medical interventions. Conclusions: The converged experience of risk and disease has led to some unsettling and generally underappreciated consequences that might be subjected to more clinical and policy reflection and response: (1) some puzzling trends in medical decision making, such as the steep and uniform increase in the numbers of women across a broad spectrum of risk/disease in breast cancer who have opted for prophylactic mastectomies; (2) a larger and highly mobilized disease/risk population, resulting in an expanded market for interventions and greater clout for disease advocates; (3) shifts in the perceived severity of the disease, with ripple effects on how people experience and understand their illness and risk of disease; and (4) interventions that promise both to reduce the risk of disease and to treat its symptoms.

Many people with diabetes have comorbidities, even multimorbidities, which have a far-reaching impact on the older adults, their family, and society. However, little is known of the experience of older adults living with comorbidities that include diabetes. The aim of this study was to explore the experience of older adults living with comorbidities including diabetes. A qualitative approach was employed. Data were collected from a selected field of 12 patients with diabetes mellitus in a medical center in northern Taiwan. The data were analyzed by Colaizzi's phenomenological methodology, and four criteria of Lincoln and Guba were used to evaluate the rigor of the study. The following 5 themes and 14 subthemes were derived: 1) expecting to heal or reduce the symptoms of the disease (trying to alleviate the distress of symptoms and trusting in health practitioners combining the use of Chinese and Western medicines); 2) comparing complex medical treatments (differences in physician practices and presentation, conditionally adhering to medical treatment, and partnering with medical professionals); 3) inconsistent information (inconsistent health information and inconsistent medical advice); 4) impacting on daily life (activities are limited and hobbies cannot be maintained and psychological distress); and 5) weighing the pros and cons (taking the initiative to deal with issues, limiting activity, adjusting mental outlook and pace of life, developing strategies for individual health regimens, and seeking support). Surmounting these challenges in order to live a normal life was explored. This study found that the experience of older adults living with comorbidities including diabetes was similar to that of a single disease, but the extent was greater than a single disease. The biggest difference is that the elderly think that their most serious problem is not diabetes, but rather, the comorbidities causing life limitations. Therefore, compared to the elderly suffering from a single disease of diabetes, medical professionals not only care about physiological data of the elderly but also pay attention to the impact of comorbidity on their lives.

Background: Only few authors have analyzed the impact of workplace conflicts and the resulting stress on the risk of developing cardiovascular disorders. The goal of this study was to analyze the association between workplace conflicts and cardiovascular disorders in patients treated by German general practitioners. Methods: Patients with an initial documentation of a workplace conflict experience between 2005 and 2014 were identified in 699 general practitioner practices (index date). We included only those who were between the ages of 18 and 65 years, had a follow-up time of at least 180 days after the index date, and had not been diagnosed with angina pectoris, myocardial infarction, coronary heart diseases, or stroke prior to the documentation of the workplace mobbing. In total, the study population consisted of 7,374 patients who experienced conflicts and 7,374 controls for analysis. The main outcome measure was the incidence of angina pectoris, myocardial infarction, and stroke correlated with workplace conflict experiences. Results: After a maximum of five years of follow-up, 2.9% of individuals who experienced workplace conflict were affected by cardiovascular diseases, while only 1.4% were affected in the control group (p-value <0.001). Workplace conflict was associated with a 1.63-fold increase in the risk of developing cardiovascular diseases. Finally, the impact of workplace conflict was higher for myocardial infarction (OR=2.03) than for angina pectoris (OR=1.79) and stroke (OR=1.56). Conclusions: Overall, we found a significant association between workplace conflicts and cardiovascular disorders. PMID:28496397

Wilson disease (WD), a genetic disorder affecting copper transport, is characterized by hepatic and neurological manifestations with variable and often unpredictable presentation. Global DNA methylation in liver was previously modified by dietary choline in tx-j mice, a spontaneous mutant model of WD. We therefore hypothesized that the WD phenotype and hepatic gene expression of tx-j offspring could be modified by maternal methyl supplementation during pregnancy. In an initial experiment, female tx-j mice or wild type mice were fed control or choline-supplemented diets 2 weeks prior to mating through embryonic day 17. Transcriptomic analysis (RNA-seq) on embryonic livers revealed tx-j-specific differences in genes related to oxidative phosphorylation, mitochondrial dysfunction, and the neurological disorders Huntington's disease and Alzheimer disease. Maternal choline supplementation restored the transcript levels of a subset of genes to wild type levels. In a separate experiment, a group of tx-j offspring continued to receive choline-supplemented or control diets, with or without the copper chelator penicillamine (PCA) for 12 weeks until 24 weeks of age. Combined choline supplementation and PCA treatment of 24-week-old tx-j mice was associated with increased liver transcript levels of methionine metabolism and oxidative phosphorylation-related genes. Sex differences in gene expression within each treatment group were also observed. These results demonstrate that the transcriptional changes in oxidative phosphorylation and methionine metabolism genes in WD that originate during fetal life are, in part, prevented by prenatal maternal choline supplementation, a finding with potential relevance to preventive treatments of WD.

Detection of recurrent Cushing's disease: proposal for standardized patient monitoring following transsphenoidal surgery.

PubMed

Ayala, Alejandro; Manzano, Alex J

2014-09-01

Transsphenoidal surgery (TSS) is first-line treatment for Cushing's disease (CD), a devastating disorder of hypercortisolism resulting from overproduction of adrenocorticotropic hormone by a pituitary adenoma. Surgical success rates vary widely and disease may recur years after remission is achieved. Recognizing CD recurrence can be challenging; although there is general acceptance among endocrinologists that patients need lifelong follow-up, there are currently no standardized monitoring guidelines. To begin addressing this need we created a novel, systematic algorithm by integrating information from literature on relapse rates in surgically-treated CD patients and our own clinical experiences. Reported recurrence rates range from 3 to 47 % (mean time to recurrence 16-49 months), emphasizing the need for careful post-surgical patient monitoring. We recommend that patients with post-operative serum cortisol <2 µg/dL (measured 2-3 days post-surgery) be monitored semiannually for 3 years and annually thereafter. Patients with post-operative cortisol between 2 and 5 µg/dL may experience persistent or subclinical CD and should be evaluated every 2-3 months until biochemical control is achieved or additional treatment is initiated. Post-operative cortisol >5 µg/dL often signifies persistent disease and second-line treatment (e.g., immediate repeat pituitary surgery, radiotherapy, and/or medical therapy) may be considered. This follow-up algorithm aims to (a) enable early diagnosis and treatment of recurrent CD, thereby minimizing the detrimental effects of hypercortisolism, and (b) begin addressing the need for standardized guidelines for vigilant monitoring of CD patients treated by TSS, as demonstrated by the reported rates of recurrence.

Foresight Infectious Diseases China Project--a novel approach to anticipating future trends in risk of infectious diseases in China: methodology and results from an initial application.

PubMed

Nicoll, A; Huang, J; Xie, Z

2009-07-09

The project devised a simple but novel methodology for identifying possible future trends in infectious diseases in animals and humans in China, of priority concern to the Chinese authorities. It used a model of disease drivers (social, economic, biological or environmental factors that affect disease outcomes, by changing the behaviour of diseases, sources or pathways) devised for the Foresight Programme in the United Kingdom. Nine families of drivers were adapted to Chinese circumstances and matrices were constructed to identify the likely relationship of single infectious diseases or families of diseases to the drivers. The likely future trends in those drivers in China were determined by interviews with 36 independent Chinese experts. These trends included not only potentially adverse animal and human movements but also opportunities for innovative surveillance methods, more use of hospitals, antimicrobials and vaccines. Some human behaviours and social trends were expected to increase the risk of infections (in particular sexually transmitted and healthcare-associated infections) while at the same time the experts thought the awareness of risk in the Chinese population would increase. The results suggested a number of areas where the Chinese authorities may experience difficulties in the future, such as rising numbers of healthcare-associated infections, zoonoses and other emerging diseases and sexually transmitted infections (including HIV). Not making firm predictions, this work identifies priority disease groups requiring surveillance and consideration of countermeasures as well as recommending strengthening basic surveillance and response mechanisms for unanticipatable zoonoses and other emerging disease threats.

2008-08-01

This qualitative study used the long interview method with Canadian mothers of African and Caribbean descent to understand the underresearched experience of raising a child with sickle cell disease (SCD). Mothers' realities were explored through three levels of social organization: daily caregiver coping (micro level); community views of SCD, such as stigma (meso level); and systemic SCD health care provision (macro level). Through the use of population health and structural social work perspectives, mothers' experiences were examined in the context of perceived gender and racial oppression. Saturation was achieved after initial interviews with 10 participants and a four-month postinterview with half of the participants. Mothers commonly reported several daily coping challenges: fear of their children's death, separation anxiety, loss of control over life, helplessness, and loneliness/isolation. SCD stigma interacted with racism, contributed to social isolation, and prevented families from organizing as a group. All mothers perceived racism as a salient factor behind inadequate mainstream SCD health care. Recommendations to improve SCD health care and implications for social work practice and research are discussed. This is the first known Canadian psychosocial study of SCD and investigation into SCD stigma outside of rural Nigeria.

To provide guidance for a public health intervention in a high caries rate multicultural population by understanding cultural issues surrounding children's oral health. Seven community focus groups were conducted with five ethnic populations (Chamorro, Filipino, Carolinian, Pohnpean, and Chuukese) living on the island of Saipan, Commonwealth of the Northern Mariana Islands, USA. Participants were asked questions about their beliefs, attitudes, knowledge, and care practices regarding issues around children's oral health. Analysis consisted of a content review of participants' responses within two targeted areas: past and current attitudes and health beliefs, and behaviours impacting risk of developing disease. Both the lack of value of baby teeth and negative parental experiences are factors underlying health beliefs and behaviours. Although some differences in beliefs and practices existed across cultural groups, most women were interested in learning about new preventive strategies to reduce dental disease. Several new mothers reported that they actively sought out parenting information during their initial pregnancy. Aversive parental experience and disregard for primary dentition were identified as serious obstacles to be addressed in order for any new programme to be effective. Despite these obstacles, new mothers were open to information and strategies to reduce the prevalence of early childhood caries.

Affective coding: the emotional dimension of agency

PubMed Central

Gentsch, Antje; Synofzik, Matthis

2014-01-01

The sense of agency (SoA) (i.e., the registration that I am the initiator and controller of my actions and relevant events) is associated with several affective dimensions. This makes it surprising that the emotion factor has been largely neglected in the field of agency research. Current empirical investigations of the SoA mainly focus on sensorimotor signals (i.e., efference copy) and cognitive cues (i.e., intentions, beliefs) and on how they are integrated. Here we argue that this picture is not sufficient to explain agency experience, since agency and emotions constantly interact in our daily life by several ways. Reviewing first recent empirical evidence, we show that self-action perception is in fact modulated by the affective valence of outcomes already at the sensorimotor level. We hypothesize that the “affective coding” between agency and action outcomes plays an essential role in agency processing, i.e., the prospective, immediate or retrospective shaping of agency representations by affective components. This affective coding of agency be differentially altered in various neuropsychiatric diseases (e.g., schizophrenia vs. depression), thus helping to explain the dysfunctions and content of agency experiences in these diseases.

Our large, urban, tertiary, university-based institution reflects on its 4-year experience with Bundled Payments for Care Improvement. We will describe the importance of 5 clinical pillars that have contributed to the early success of our bundled payment initiative. We are convinced that value-based care delivered through bundled payment initiatives is the best method to optimize patient outcomes while rewarding surgeons and hospitals for adapting to the evolving healthcare reforms. We summarize a number of experiences and lessons learned since the implementation of Bundled Payments for Care Improvement at our institution. Our experience has led to the development of more refined clinical pathways and coordination of care through evidence-based approaches. We have established that the success of the bundled payment program rests on the following 5 main clinical pillars: (1) optimizing patient selection and comorbidities; (2) optimizing care coordination, patient education, shared decision making, and patient expectations; (3) using a multimodal pain management protocol and minimizing narcotic use to facilitate rapid rehabilitation; (4) optimizing blood management, and standardizing venous thromboembolic disease prophylaxis treatment by risk standardizing patients and minimizing the use of aggressive anticoagulation; and (5) minimizing post-acute facility and resource utilization, and maximizing home resources for patient recovery. From our extensive experience with bundled payment models, we have established 5 clinical pillars of value for bundled payments. Our hope is that these principles will help ease the transition to value-based care for less-experienced healthcare systems. Copyright © 2017 Elsevier Inc. All rights reserved.

Rocky Mountain spotted fever at Koair Children's Hospital, 1990-2002.

2004-05-01

The reported average annual incidence of Rocky Mountain spotted fever (RMSF) in Kentucky is less than 5 per million population, although seroprevalence studies suggest that exposure to Rickettsia riskettsii, the causative agent, is relatively common among children. The experience with RMSF at Kosair Children's Hospital over a 12-year period was reviewed. Fifteen cases were identified (5 boys and 10 girls). Illness onset ranged from April to October, and 4 patients resided in Jefferson County. The classic triad of fever, rash, and headache was present in only 60% of cases, and tick attachment was reported in only 40%. On average, 6 days elapsed from onset of symptoms to initiation of appropriate antibiotic therapy. One patient suffered splenic infarction and necrosis of the digits due to shock and disseminated intravascular coagulopathy, and 2 patients died. RMSF is a significant cause of pediatric morbidity and mortality in this region of Kentucky. Affected children may reside in relatively urban parts of the state. Initial clinical features may be nonspecific. This, as well as decreased awareness of disease and (unjustified) reluctance to use doxycycline may contribute to delays in initiating therapy.

The First Endoscopy in Suspected Inflammatory Bowel Disease.

In a patient presenting with suspected inflammatory bowel disease, the initial endoscopic evaluation is a valuable tool for determining the correct disease diagnosis and the extent and severity of disease. A full colonoscopy and ileoscopy should be performed when possible, with systematic biopsies from each segment. When a diagnosis of inflammatory bowel disease is established, it is possible to distinguish between Crohn disease and ulcerative colitis, and specific endoscopic features may assist in this categorization. Because patchy healing can occur with treatment, it is important to obtain a thorough and accurate assessment of disease characteristics and distribution before initiating therapy.

This is an exploratory study that explores the experiences of lactating women in initiating, continuing, or discontinuing breastfeeding in an urban area of Karachi, Pakistan. Objectives. To explore the experiences of lactating women and to understand their support and hindering mechanisms in initiating and maintaining breastfeeding. Methods. This is an exploratory design assisting in exploring the participant's experiences of initiating and maintaining breastfeeding to better understand their world. Purposive sampling was used, and data was analyzed through manual thematic analysis. Results. The data revealed that mother's knowledge, sociocultural environment, breastfeeding decision, and self- and professional support acted as driving forces for the participants. However, sociocultural environment, physiological changes, time management, and being a housewife to breastfeed their children were all challenges and barriers that the participants thought hindered their breastfeeding initiation and maintenance. Conclusion. Breastfeeding is a natural but taxing phenomenon, and breastfeeding mothers experience supporting and hindering factors in initiating and maintaining breastfeeding. PMID:22389780

2001-02-01

From April 1998 to March 2000, a cytomegalovirus (CMV) antigenemia-guided pre-emptive approach for CMV disease was evaluated in 77 adult patients who received allogeneic hematopoietic stem cell transplantation at the National Cancer Center Hospital. A CMV antigenemia assay was performed at least once a week after engraftment. High-level antigenemia was defined as a positive result with 10 or more positive cells per 50 000 cells and low-level antigenemia was defined as less than 10 positive cells. Among the 74 patients with initial engraftment, 51 developed positive antigenemia. Transplantation from alternative donors and the development of grade II-IV GVHD were independent risk factors for positive antigenemia. Ganciclovir was administered as pre-emptive therapy in 39 patients in a risk-adapted manner. None of the nine low-risk patients with low-level antigenemia as their initial positive result developed high-level antigenemia even though ganciclovir was withheld. Only one patient developed early CMV disease (hepatitis) during the study period. CMV antigenemia resolved in all but two cases, in whom ganciclovir was replaced with foscarnet. In eight patients, however, the neutrophil count decreased to 0.5 x 10(9)/l or less after starting ganciclovir, including three with documented infections and two with subsequent secondary graft failure. The total amount of ganciclovir and possibly the duration of high-dose ganciclovir might affect the incidence of neutropenia. We concluded that antigenemia-guided pre-emptive therapy with a decreased dose of ganciclovir and response-oriented dose adjustment might be appropriate to decrease the toxicity of ganciclovir without increasing the risk of CMV disease.

Introduction This study examined feasibility of a place-based community health worker (CHW) and health advocate (HA) initiative in five public housing developments selected for high chronic disease burden and described early outcomes. Methods This intervention was informed by a mixed-method needs assessment performed December 2014–January 2015 (representative telephone survey, n=1,663; six focus groups, n=55). Evaluation design was a non-randomized, controlled quasi-experiment. Intake and 3-month follow-up data were collected February–December 2015 (follow-up response rate, 93%) on 224 intervention and 176 comparison participants, and analyzed in 2016. All participants self-reported diagnoses of hypertension, diabetes, or asthma. The intervention consisted of chronic disease self-management and goal setting through six individual CHW-led health coaching sessions, instrumental support, and facilitated access to insurance/clinical care navigation from community-based HAs. Feasibility measures included CHW service satisfaction and successful goal setting. Preliminary outcomes included clinical measures (blood pressure, BMI); disease management behaviors and self-efficacy; and preventive behaviors (physical activity). Results At the 3-month follow-up, nearly all intervention participants reported high satisfaction with their CHW (90%) and HA (76%). Intervention participants showed significant improvements in self-reported physical activity (p=0.005) and, among hypertensive participants, self-reported routine blood pressure self-monitoring (p=0.013) compared with comparison participants. No improvements were observed in self-efficacy or clinical measures at the 3-month follow-up. Conclusions Housing-based initiatives involving CHW and HA teams are acceptable to public housing residents and can be effectively implemented to achieve rapid improvements in physical activity and chronic disease self-management. At 3-month assessment, additional time and efforts are required to improve clinical outcomes. PMID:28215382

Estrogen and other sex hormones have received a great deal of attention for their speculative role in Alzheimer's disease (AD), but at present a direct connection between estrogen and the pathogenesis of AD remains elusive and somewhat contradictory. For example, on one hand there is a large body of evidence suggesting that estrogen is neuroprotective and improves cognition, and that hormone replacement therapy (HRT) at the onset of menopause reduces the risk of developing AD decades later. However, on the other hand, studies such as the Women's Health Initiative demonstrate that HRT initiated in elderly women increases the risk of dementia. While estrogen continues to be investigated, the disparity of findings involving HRT has led many researchers to examine other hormones of the hypothalamic-pituitary-gonadal axis such as luteinising hormone (LH) and follicle-stimulating hormone. In this review, we propose that LH, rather than estrogen, is the paramount player in the pathogenesis of AD. Notably, both men and women experience a 3- to 4-fold increase in LH with aging, and LH receptors are found throughout the brain following a regional pattern remarkably similar to those neuron populations affected in AD. With respect to disease, serum LH level is increased in women with AD relative to non-diseased controls, and levels of LH in the brain are also elevated in AD. Mechanistically, we propose that elevated levels of LH may be a fundamental instigator responsible for the aberrant reactivation of the cell cycle that is seen in AD. Based on these aforementioned aspects, clinical trials underway with leuprolide acetate, a gonadotropin-releasing hormone agonist that ablates serum LH levels, hold great promise as a ready means of treatment in individuals afflicted with AD.

Necrotizing enterocolitis, a rare but severe condition with insidious postoperative complications.

Necrotizing enterocolitis (NEC) is one of the most frequent causes of gastrointestinal perforation in premature neonates, only few case series and reports being described in adult patients. Early in the course of the disease, superficial mucosal ulceration, sub mucosal edema and hemorrhage occur. Further progression leads to transmural necrosis leading sometimes to bowel perforation. Six cases encountered in our clinic in recent years led us to resume discussions on necrotizing enteritis, not because it is a rare disease, but due to the severe postoperative complications. Our lot consisted of four stage 1 patients and two with Bell stage III NEC and severe intestinal injury, necrosis, and perforation. All of the patients were diagnosed preoperatory with other surgical conditions, like appendicitis with peritonitis, perforated duodenal ulcer or acute cholecystitis. We present to review two cases. For patients undergoing laparotomy, resection of the involved intestine mandates either enterostomy formation or primary anastomosis. An intermediate option is laparotomy with intestinal resection and delayed anastomosis 48 to 72 hours later. Because of the small number of patients in our lot, we cannot advise a certain surgical treatment, but a strategy involving bienterostomyper primam should be further analyzed. The choice of operative intervention reflects multiple variables, including age, physiologic status, institutional resources and surgeon preference based on experience. Primary peritoneal drainage for perforated NEC may help to resuscitate and treat a critically ill patient initially, and in some instances, may be definitive operative intervention. Relatively rare disease, of unknown etiology and elusive pathogenesis, NEC has initial non-specific symptoms and clinical features that mimic more common surgical diseases. There is considerable controversy regarding which procedure is preferable. Currently, in the absence of rigorous evidence supporting the superiority of one approach over the other, surgical intervention depends mostly on the treating institution or the individual surgeon.

The efficacy of BAY 57-1293, a novel non-nucleosidic inhibitor of herpes simplex virus 1 and 2 (HSV-1 and HSV-2), bovine herpesvirus and pseudorabies virus, was studied in the guinea pig model of genital herpes in comparison with the licensed drug valaciclovir (Valtrex). Early therapy with BAY 57-1293 almost completely suppressed the symptoms of acute HSV-2 infection, and reduced virus shedding and viral load in the sacral dorsal root ganglia by up to three orders of magnitude, resulting in decreased latency and a greatly diminished frequency of subsequent recurrent episodes. In contrast, valaciclovir showed only moderate effects in this set of experiments. When treatment was initiated late during the course of disease after symptoms were apparent, that is, a setting closer to most clinical situations, the efficacy of therapy with BAY 57-1293 was even more pronounced. Compared with valaciclovir, BAY 57-1293 halved the time necessary for complete healing. Moreover, the onset of action was fast, so that only very few animals developed new lesions after treatment commenced. Finally, in a study addressing the treatment of recurrent disease in animals whose primary infection had remained untreated BAY 57-1293 was efficient in suppressing the episodes. In summary, superior potency and efficacy of BAY 57-1293 over standard treatment with valaciclovir was demonstrated in relevant animal models of human genital herpes disease in terms of abrogating an HSV infection, reducing latency and the frequency of subsequent recurrences. Furthermore, BAY 57-1293 shortens the time to healing even if initiation of therapy is delayed.

To assess whether coronary heart disease mortality in Finnish hormone therapy (HT) users differed before and after 2002 when the Women's Health Initiative study was published. The risks of coronary heart disease death in HT users in relation to the age-matched background population were compared between the pre- (1995-2001) and post- (2002-2009) Women's Health Initiative eras. We used a nationwide register on HT (ie, estradiol with or without progestin) reimbursement and linked them to causes of death in 290,272 women aged 40 years or older. Exposure to HT for 1 year or less was accompanied by a 29% reduction (0.71; 0.63-0.80; three per 10,000 fewer deaths) and an exposure of 1-8 years with a 43% reduction (0.57; 0.48-0.66; three per 10,000 fewer deaths) in the risk of coronary heart disease death in the pre-Women's Health Initiative era. In the post-Women's Health Initiative era, HT use of 1 year or less was associated with an 18% reduction (0.82; 0.76-1.00; one per 10,000 fewer deaths) and an exposure of 1-8 years with a 54% reduction (0.46; 0.32-0.64; two per 10,000 fewer deaths) in coronary heart disease mortality. Discontinuation of HT was associated with an increased risk of cardiac death of 42% (1.42; 1.17-1.71; seven per 10,000 extra deaths) in the pre-Women's Health Initiative era and 31% (1.31; 0.92-1.82; two per 10,000 extra deaths) in the post-Women's Health Initiative era during the first posttreatment year. This risk increase vanished in further follow-up during both eras. Changes in HT use after the Women's Health Initiative failed to affect coronary heart disease mortality of HT users in this nationwide study.

Importance Optimizing assessments of rate of progression in Parkinson Disease (PD) is important in designing clinical trials, especially of potential disease-modifying agents. Objective To examine the value of measures of impairment, disability, and quality of life in assessing progression in early Parkinson disease. Design, Setting, and Participants Inception cohort analysis of data from 413 early, untreated PD patients, who were enrolled in two multicenter, randomized, double-blind clinical trials. Intervention Participants were randomized into five treatments: 67 received creatine, 66 minocycline, 71 Coenzyme Q10, 71 GPI-1485, and 138 placebo. We assessed the association between the rates of change in measures of impairment, disability, and quality of life and time to initiation of symptomatic treatment. Main Outcome Measure Time between baseline assessment and need for the initiation of symptomatic pharmaceutical treatment for PD was the primary indicator of disease progression. Results After adjusting for baseline confounding variables Unified Parkinson Disease Rating Scale (UPDRS) II, UPDRS III, modified Rankin score (mRS), level of education, and treatment group, the rate of change of the following measurements was assessed: UPDRS II, UPDRS III, Schwab and England ADL (S&E), Total Functional Capacity (TFC), Parkinson’s Disease Quality of Life Questionnaire – 39 (PDQ39) ADL and Summary Index (SI), Short Form -12v2 Health Survey (SF12) Physical Summary (PS), and SF12 Mental Summary (MS). Variables reaching statistical threshold in univariate analysis were entered into a multivariable Cox proportional hazards model using time to symptomatic treatment as the dependent variable. More rapid worsening of UPDRS II (HR 1.15, 95% C.I. 1.08 – 1.22 for 1 scale unit change per 6 months), UPDRS III (HR 1.09; 95% C.I. 1.06 – 1.13 for 1 scale unit change per 6 months), and S&E (HR 1.29 95% C.I. 1.12 – 1.48 for 5 percentage point change per 6 months), was associated with earlier need for symptomatic therapy. Conclusions and Relevance In early PD, UPDRS II and III, and S&E can be used to measure disease progression, while the PDQ39 ADL, PDQ39 SI, TFC, SF12 PH, and SF12 MH are not sensitive to change.

Increasing longevity for Inuit living in Nunavik, northern Quebec, has resulted in heightened rates of cancers and chronic diseases necessitating complex treatments. Consequently, end-of-life (EOL) care, once the domain of Inuit families and communities, has come to include professionalized healthcare providers with varying degrees of awareness of factors to consider in providing care to Inuit populations. To better understand the factors shaping EOL care in Nunavik to support the development of a sustainable model of care. Using focused ethnography, we conducted participant observations and informal and semistructured interviews with 103 participants (community members, healthcare practitioners, and administrators) across Nunavik and in Montreal, the affiliated tertiary care center. Data domains included the following: care trajectories; patient and family experiences receiving and providing EOL care; local and urban resources and challenges; and ways forward. Sociocultural, historical, and geographic factors shape EOL care in Nunavik, presenting a complex set of challenges for Inuit patients, families, and healthcare providers. A sustainable model of EOL care requires building on shared initiatives, capitalizing on the existing strengths in communities, and attending to the multiple bereavement needs in the region. Building a sustainable model of EOL care requires respectful collaboration among governing structures, healthcare institutions, and community members. It must centrally value local knowledge and initiatives. To ensure Inuit families and patients are supported throughout the dying process, future initiatives must centrally include local stakeholders in both the design and evaluation of any changes to the current healthcare system.

Accurate monitoring leads to effective control and greater learning of patient education materials.

Effective management of chronic diseases (e.g., diabetes) can depend on the extent to which patients can learn and remember disease-relevant information. In two experiments, we explored a technique motivated by theories of self-regulated learning for improving people's learning of information relevant to managing a chronic disease. Materials were passages from patient education booklets on diabetes from NIDDK. Session 1 included an initial study trial, Session 2 included self-regulated restudy, and Session 3 included a final memory test. The key manipulation concerned the kind of support provided for self-regulated learning during Session 2. In Experiment 1, participants either were prompted to self-test and then evaluate their learning before selecting passages to restudy, were shown the prompt questions but did not overtly self-test or evaluate learning prior to selecting passages, or were not shown any prompts and were simply given the menu for selecting passages to restudy. Participants who self-tested and evaluated learning during Session 2 had a small but significant advantage over the other groups on the final test. Secondary analyses provided evidence that the performance advantage may have been modest because of inaccurate monitoring. Experiment 2 included a group who also self-tested but who evaluated their learning using idea-unit judgments (i.e., by checking their responses against a list of key ideas from the correct response). Participants who self-tested and made idea-unit judgments exhibited a sizable advantage on final test performance. Secondary analyses indicated that the performance advantage was attributable in part to more accurate monitoring and more effective self-regulated learning. An important practical implication is that learning of patient education materials can be enhanced by including appropriate support for learners' self-regulatory processes.

Deep brain stimulation (DBS) is an effective treatment for essential tremor (ET) and dystonia. After surgery, a number of extensive programming sessions are performed, mainly relying on neurologist's personal experience as no programming guidelines have been provided so far, with the exception of recommendations provided by groups of experts. Finally, fewer information is available for the management of DBS in ET and dystonia compared with Parkinson's disease. Our aim is to review the literature on initial and follow-up DBS programming procedures for ET and dystonia and integrate the results with our current practice at Toronto Western Hospital (TWH) to develop standardized DBS programming protocols. We conducted a literature search of PubMed from inception to July 2014 with the keywords "balance", "bradykinesia", "deep brain stimulation", "dysarthria", "dystonia", "gait disturbances", "initial programming", "loss of benefit", "micrographia", "speech", "speech difficulties" and "tremor". Seventy-six papers were considered for this review. Based on the literature review and our experience at TWH, we refined three algorithms for management of ET, including: (1) initial programming, (2) management of balance and speech issues and (3) loss of stimulation benefit. We also depicted algorithms for the management of dystonia, including: (1) initial programming and (2) management of stimulation-induced hypokinesia (shuffling gait, micrographia and speech impairment). We propose five algorithms tailored to an individualized approach to managing ET and dystonia patients with DBS. We encourage the application of these algorithms to supplement current standards of care in established as well as new DBS centers to test the clinical usefulness of these algorithms in supplementing the current standards of care.

Repeat workers' compensation claims: risk factors, costs and work disability

PubMed Central

2011-01-01

Background The objective of our study was to describe factors associated with repeat workers' compensation claims and to compare the work disability arising in workers with single and multiple compensation claims. Methods All initial injury claims lodged by persons of working age during a five year period (1996 to 2000) and any repeat claims were extracted from workers' compensation administrative data in the state of Victoria, Australia. Groups of workers with single and multiple claims were identified. Descriptive analysis of claims by affliction, bodily location, industry segment, occupation, employer and workplace was undertaken. Survival analysis determined the impact of these variables on the time between the claims. The economic impact and duration of work incapacity associated with initial and repeat claims was compared between groups. Results 37% of persons with an initial claim lodged a second claim. This group contained a significantly greater proportion of males, were younger and more likely to be employed in manual occupations and high-risk industries than those with single claims. 78% of repeat claims were for a second injury. Duration between the claims was shortest when the working conditions had not changed. The initial claims of repeat claimants resulted in significantly (p < 0.001) lower costs and work disability than the repeat claims. Conclusions A substantial proportion of injured workers experience a second occupational injury or disease. These workers pose a greater economic burden than those with single claims, and also experience a substantially greater cumulative period of work disability. There is potential to reduce the social, health and economic burden of workplace injury by enacting prevention programs targeted at these workers. PMID:21696637

Objective A multidisciplinary approach is advocated for the management of Non-Alcoholic Fatty Liver Disease (NAFLD), but few clinical data exist to support this. The objective of this study was to investigate the effectiveness of a multidisciplinary NAFLD clinic using surrogate markers of liver injury and cardiovascular risk. Design Retrospective survey of clinical practice. Setting The multidisciplinary NAFLD clinic in a secondary/tertiary care setting with hepatology, diabetology, dietetic and exercise therapy input: initial 5-years’ experience (2007–2012). Patients 180 patients with NAFLD but without hepatic comorbidities were followed up for a median of 19.5 (range 3–57) months. 52% had type 2 diabetes mellitus, 48% were Europoid Caucasian, 17% were South Asian. Interventions Multiple clinical interventions were employed including lifestyle (diet and exercise) advice, pharmacological intervention for cardiovascular risk factors, weight loss and exercise therapy. Main outcome measures Change in alanine aminotransferase (ALT), weight, HbA1c, lipid profile and blood pressure. Results Median ALT fell from 61 (12–270) U/l to 50 (11–221) U/l, −18%, p<0.001, and weight fell from 90.5 (42.7–175.0) kg to 87.3 (45.9–175.3) kg, −3.5%, p<0.001. There were significant improvements in total cholesterol overall, triglycerides (among dyslipidaemic patients), HbA1c (among diabetic patients) and systolic blood pressure (among hypertensive patients). 24% of patients achieved ≥7% weight loss during follow-up and 17% maintained this weight loss throughout. Conclusions Improvement in liver biochemistry and cardiovascular risk factors was seen in patients attending the multidisciplinary NAFLD clinic. Refinement of this approach is warranted in light of these data, novel therapies and a growing evidence base. PMID:28839736

Background Classic trajectories of illness at end of life (EOL) suggest different care needs for patients with cancer versus chronic obstructive pulmonary disease (COPD) and may lead to different experiences of transitions over the course of a life-limiting illness. Patients may experience transitions in different ways than clinicians. No prior studies have examined this issue from patients’, families’, and clinicians’ perspectives. Objectives We sought to explore transitions, defined as experiences that patients and family members viewed as milestones in the evolution of their illnesses and therapies, and compare these perceptions with the perspectives of the patient’s physician and nurse to provide insights about communication concerning EOL care. Methods We conducted a qualitative study using grounded theory to examine participants’ perspectives on the experiences of key transitions in the context of living with advanced COPD or cancer. In-depth interviews with patients, family members, nurses, and physicians were conducted by experienced interviewers. Results Six themes were identified regarding participants’ experiences with transitions. Themes that defined transitions among both patients with COPD and those with cancer included: new or different treatments and no more treatments available. Themes unique to patients with COPD were activity limitations due to functional decline and initiation of oxygen therapy. One theme unique to clinicians was acute exacerbation of illness or hospitalization. Conclusions This study identified differences in the meaning of transitions for patients versus clinicians and for patients with COPD versus those with cancer. These findings may offer clinicians the opportunity to provide a more patient-centered approach to communication about end-of-life care by acknowledging and addressing transitions in palliative care from the perspective of the patient and family.

To determine the risk of rheumatic disease flare and adverse effects in patients with preexisting rheumatic disease who were receiving immune checkpoint inhibitor (ICI) therapy. A retrospective medical record review was performed to identify all patients who received ICI therapy at Mayo Clinic in Rochester, Minnesota between 2011 and 2016 (~700 patients). Those with a preexisting rheumatic disease were identified using specific diagnostic codes. Sixteen patients were identified (81% female, median age 68.5 years). The most common rheumatic diseases were rheumatoid arthritis (n = 5), polymyalgia rheumatica (n = 5), Sjögren's syndrome (n = 2), and systemic lupus erythematosus (n = 2). Seven patients were receiving immunosuppressive therapy or glucocorticoids for their rheumatic disease at the time of initiation of the ICI. The primary malignancies were melanoma (n = 10), pulmonary (n = 4), or hematologic (n = 2). In most cases, ICIs were offered only after failure of several other therapies. Immune-related adverse effects (IRAEs) occurred in 6 patients, and all were treated successfully with glucocorticoids and discontinuation of the ICI therapy. There were no significant differences in time from cancer diagnosis to immunotherapy, duration of immunotherapy, age, or sex between the patients with and those without IRAEs. To our knowledge, this represents the largest single-center cohort of patients with rheumatic diseases who were exposed to modern cancer immunotherapy. Only a minority of these patients experienced a flare of their preexisting rheumatic disease or any other IRAE. © 2017, American College of Rheumatology.

Chickenpox is highly contagious childhood disease which occurs as a result of varicella-zoster virus primary infection. Symptomatic therapy is usually adequate for chickenpox, but in some cases it requires combinations of antiviral drugs and antibiotics. To present our expirience with chickenpox therapy in children and adult patients. Study included 120 randomly chosen patients, 60 adults and 60 children, with confirmed chickenpox infection, hospitalised at Clinic for infectious diseases in Sarajevo. Observed period was 1st January 2005. to 30th June 2011. We compared used therapy and outcome of disease. We had 333 patients with confirmed chickenpox in mentioned period. Male sex prevailed. Antiviral (acyclovir) therapy was initiated in 8(13.5%) adults and 16(27%) children. Most frequently used antibiotic was Co-Amoxiclav in a group of adults and Ceftriaxone in a group of children.

Symptomatic treatment is indicated in all immunocompetent patients with no signs of complications. Use of corticosteroids remains open dillemma. Our therapeutical approcach followed by actual guidelines proved to be usefull. No death cases were recorded in these

The Hundred Person Wellness Project and Google's Baseline Study: medical revolution or unnecessary and potentially harmful over-testing?

PubMed

Diamandis, Eleftherios P

2015-01-09

The Hundred Person Wellness Project is an ambitious pilot undertaking, which aims to intensely monitor 100 individuals over 10 months. Patients with abnormal findings will be treated, in hopes that this early intervention will avoid, or delay, symptomatic disease. Google's "Baseline Study" is of similar scope and will enroll 10,000 people over 2 to 3 years. I here speculate that these approaches will likely not be effective in preventing disease, but instead, lead to unnecessary and potentially harmful interventions. Examples from the cancer screening experience over the last 30 years are provided, which show that intensive testing may uncover indolent disease or incidental findings which, when treated, may cause more harm than good. Additional examples show that aggressive treatments for cancer and other diseases do not always lead to better patient outcomes. I conclude that the recent advances in omics provide us with unprecedented opportunities for high content clinical testing, but such testing should be used with caution to avoid the harmful consequences of over-diagnosis and over-treatment. Despite the detailed rebuttals by Hood and colleagues in another commentary in BMC Medicine, time will show the actual benefits and harms of these ambitious initiatives.

Sustaining a Focus on Health Equity at the Centers for Disease Control and Prevention Through Organizational Structures and Functions.

The public health infrastructure required for achieving health equity is multidimensional and complex. The infrastructure should be responsive to current and emerging priorities and capable of providing the foundation for developing, planning, implementing, and evaluating health initiatives. This article discusses these infrastructure requirements by examining how they are operationalized in the organizational infrastructure for promoting health equity at the Centers for Disease Control and Prevention, utilizing the nation's premier public health agency as a lens. Examples from the history of the Centers for Disease Control and Prevention's work in health equity from its centers, institute, and offices are provided to identify those structures and functions that are critical to achieving health equity. Challenges and facilitators to sustaining a health equity organizational infrastructure, as gleaned from the Centers for Disease Control and Prevention's experience, are noted. Finally, we provide additional considerations for expanding and sustaining a health equity infrastructure, which the authors hope will serve as "food for thought" for practitioners in state, tribal, or local health departments, community-based organizations, or nongovernmental organizations striving to create or maintain an impactful infrastructure to achieve health equity.

The serendipitous discovery of triggered autobiographical memories and eventual memory improvement in an obese patient who received fornix deep brain stimulation in 2008 paved the way for several phase I and phase II clinical trials focused on the safety and efficacy of this potential intervention for people with Alzheimer's disease. In this article, we summarize clinical trials and case reports on fornix deep brain stimulation for Alzheimer's disease and review experiments on animal models evaluating the physiological or behavioral effects of this intervention. Based on information from these reports and studies, we identify potential translational challenges of this approach and determine practical and ethical considerations for clinical trials, focusing on issues regarding selection criteria, trial design, and outcome evaluation. Based on initial results suggesting greater benefit for those with milder disease stage, we find it essential that participant expectations are carefully managed to avoid treatment disenchantment and/or frustration from participants and caregivers. Finally, we urge for collaboration between centers to establish proper clinical standards and to promote better trial results comparison. Copyright © 2017 Elsevier Inc. All rights reserved.

Omega-3 fatty acids in neurodegenerative diseases: focus on mitochondria.

PubMed

Eckert, Gunter P; Lipka, Uta; Muller, Walter E

2013-01-01

Mitochondrial dysfunction represents a common early pathological event in brain aging and in neurodegenerative diseases, e.g., in Alzheimer's (AD), Parkinson's (PD), and Huntington's disease (HD), as well as in ischemic stroke. In vivo and ex vivo experiments using animal models of aging and AD, PD, and HD mainly showed improvement of mitochondrial function after treatment with polyunsaturated fatty acids (PUFA) such as docosahexaenoic acid (DHA). Thereby, PUFA are particular beneficial in animals treated with mitochondria targeting toxins. However, DHA showed adverse effects in a transgenic PD mouse model and it is not clear if a diet high or low in PUFA might provide neuroprotective effects in PD. Post-treatment with PUFA revealed conflicting results in ischemic animal models, but intravenous administered DHA provided neuroprotective efficacy after acute occlusion of the middle cerebral artery. In summary, the majority of preclinical data indicate beneficial effects of n-3 PUFA in neurodegenerative diseases, whereas most controlled clinical trials did not meet the expectations. Because of the high half-life of DHA in the human brain clinical studies may have to be initiated much earlier and have to last much longer to be more efficacious. Copyright © 2012 Elsevier Ltd.

2017-08-01

Chronic cardiovascular diseases (CVD) are diseases with marked morbidity. Patients are often advised to change their lifestyle to prevent complications and impairment of their diseases. Compliance, however, is influenced by multiple factors. Initial studies show that spirituality is an important aspect in health behavior and lifestyle changing, but to health professionals like nurses this is unknown. The aim of this review is to investigate and synthesize evidence about the role of spirituality in lifestyle changing in patients with chronic CVD. A comprehensive search was conducted in electronic databases Academic Search Premier, E-journals, Medline and PubMed, published between the years 2000-2015. After selection based on pre-set inclusion criteria, studies were retrieved and evaluated on quality using the criteria of the QOREC. Twelve studies with a qualitative empirical design and mixed methods were included. This review shows that spirituality, is related to the self-management of patients with chronic diseases. For instance, lifestyle changes are experienced as a continuous inner battle. Religion gives strength, but is also experienced as a struggle. Feelings of guilt and becoming a victim influence patients' experience. For effectively advising patients with CVD on lifestyle changes, nurses cannot ignore this factor but further investigation is required.

Analysis of phase II methodologies for single-arm clinical trials with multiple endpoints in rare cancers: An example in Ewing's sarcoma.

PubMed

Dutton, P; Love, S B; Billingham, L; Hassan, A B

2018-05-01

Trials run in either rare diseases, such as rare cancers, or rare sub-populations of common diseases are challenging in terms of identifying, recruiting and treating sufficient patients in a sensible period. Treatments for rare diseases are often designed for other disease areas and then later proposed as possible treatments for the rare disease after initial phase I testing is complete. To ensure the trial is in the best interests of the patient participants, frequent interim analyses are needed to force the trial to stop promptly if the treatment is futile or toxic. These non-definitive phase II trials should also be stopped for efficacy to accelerate research progress if the treatment proves to be particularly promising. In this paper, we review frequentist and Bayesian methods that have been adapted to incorporate two binary endpoints and frequent interim analyses. The Eurosarc Trial of Linsitinib in advanced Ewing Sarcoma (LINES) is used as a motivating example and provides a suitable platform to compare these approaches. The Bayesian approach provides greater design flexibility, but does not provide additional value over the frequentist approaches in a single trial setting when the prior is non-informative. However, Bayesian designs are able to borrow from any previous experience, using prior information to improve efficiency.

Post-traumatic Stress Disorder and Cardiovascular Disease.

PubMed

Burg, Matthew M; Soufer, Robert

2016-10-01

Post-traumatic stress disorder (PTSD) is a disabling condition that develops consequent to trauma exposure such as natural disasters, sexual assault, automobile accidents, and combat that independently increases risk for early incident cardiovascular disease (CVD) and cardiovascular (CV) mortality by over 50 % and incident hypertension risk by over 30 %. While the majority of research on PTSD and CVD has concerned initially healthy civilian and military veteran samples, emerging research is also demonstrating that PTSD consequent to the trauma of an acute cardiac event significantly increases risk for early recurrence and mortality and that patient experiences in the clinical pathway that are related to the emergency department environment may provide an opportunity to prevent PTSD onset and thus improve outcomes. Future directions for clinical and implementation science concern broad PTSD and trauma screening in the context of primary care medical environments and the testing of PTSD treatments with CVD-related surrogates and endpoints.

Prospective cohorts have played a major role in understanding the contribution of diet, physical activity, medical conditions, and genes to the development of many diseases, but have not been widely used for occupational exposures. Studies in agriculture are an exception. We draw upon our experience using this design to study agricultural workers to identify conditions that might foster use of prospective cohorts to study other occupational settings. Prospective cohort studies are perceived by many as the strongest epidemiologic design. It allows updating of information on exposure and other factors, collection of biologic samples before disease diagnosis for biomarker studies, assessment of effect modification by genes, lifestyle, and other occupational exposures, and evaluation of a wide range of health outcomes. Increased use of prospective cohorts would be beneficial in identifying hazardous exposures in the workplace. Occupational epidemiologists should seek opportunities to initiate prospective cohorts to investigate high priority, occupational exposures. PMID:25603935

To evaluate mortality rates among a cohort of jet engine manufacturing workers. Subjects were 222,123 workers employed from 1952 to 2001. Vital status was determined through 2004 for 99% of subjects and cause of death for 95% of 68,317 deaths. We computed standardized mortality ratios and modeled internal cohort rates. Mortality excesses reported initially no longer met the criteria for further investigation. We found two chronic obstructive pulmonary disease-related mortality excesses that met the criteria in two of eight study plants. At the total cohort level, chronic obstructive pulmonary disease-related categories were not related to any factors or occupational exposures considered. A full evaluation of these excesses was limited by lack of data on smoking history. Occupational exposures received outside of work or uncontrolled positive confounding by smoking cannot be ruled out as reasons for these excesses.

After an anthropologic psychiatric experience done in the Gran Chaco Gualamba, by the end of the 60s, Pages Larraya and his team developed the theory of Cultural Isoidias, zones into which the country could be divided for epidemiologic studies. This article summarizes some of the principal lines of investigation of this program which departures from an initial study of the prevalence of mental diseases in Argentina. Other lines of research (such as a study about marginality, about Alzheimer's disease, about alcoholism and about AIDS) are summarized very briefly so as to give the reader an idea about the enormous field of study embraced by the PEPSI.

Among the many benefits of the Human Genome Project are new and powerful tools such as the genome-wide hybridization devices referred as microarrays. Initially designed to measure gene transcriptional levels, microarray technologies are now used for comparing other genome features among individuals and their tissues and cells. Results provide valuable information on disease subcategories, disease prognosis, and treatment outcome. Likewise, reveal differences in genetic makeup, regulatory mechanisms and subtle variations are approaching the era of personalized medicine. To understand this powerful tool, its versatility and how it is dramatically changing the molecular approach to biomedical and clinical research, this review describes the technology, its applications, a didactic step-by-step review of a typical microarray protocol, and a real experiment. Finally, it calls the attention of the medical community to integrate multidisciplinary teams, to take advantage of this technology and its expanding applications that in a slide reveals our genetic inheritance and destiny.

Maple syrup urine disease is caused by a deficiency in the branched chain ketoacid dehydrogenase (BCKAD) complex. This results in the accumulation of branched chain amino acids (BCAA) and branched chain ketoacids in the body. Even when aggressively treated with dietary restriction of BCAA, patients experience long term cognitive, neurological and psychosocial problems. Liver transplantation from deceased donors has been shown to be an effective modality in introducing adequate BCKAD activity, attaining a metabolic cure for patients. Here, we report the clinical course of the first known patient with classic MSUD who received two consecutive partial liver grafts from two different living non-carrier donors and his five year outcome posttransplant. We also show that despite the failure of the first liver graft, and initial acute cellular rejection of the second liver graft in our patient, his metabolic control remained good without metabolic decompensation.

After the launch of the US President's Emergency Plan for AIDS Relief in 2003, it became evident that inadequate laboratory systems and services would severely limit the scale-up of human immunodeficiency virus infection prevention, care, and treatment programs. Thus, the Office of the US Global AIDS Coordinator, Centers for Disease Control and Prevention, and Becton, Dickinson and Company developed a public-private partnership (PPP). Between October 2007 and July 2012, the PPP combined the competencies of the public and private sectors to boost sustainable laboratory systems and develop workforce skills in 4 African countries. Key accomplishments of the initiative include measurable and scalable outcomes to strengthen national capacities to build technical skills, develop sample referral networks, map disease prevalence, support evidence-based health programming, and drive continuous quality improvement in laboratories. This report details lessons learned from our experience and a series of recommendations on how to achieve successful PPPs. PMID:27025696

2014-01-01

Chronic kidney disease is a major public health problem globally. Despite this, there are fewer high-quality, high-impact clinical trials in nephrology than other internal medicine specialties, which has led to large gaps in evidence. To address this deficiency, the Australasian Kidney Trials Network, a Collaborative Research Group, was formed in 2005. Since then, the Network has provided infrastructure and expertise to conduct patient-focused high-quality, investigator-initiated clinical trials in nephrology. The Network has not only been successful in engaging the nephrology community in Australia and New Zealand but also in forming collaborations with leading researchers from other countries. This article describes the establishment, development, and functions of the Network. The article also discusses the current and future funding strategies to ensure uninterrupted conduct of much needed clinical trials in nephrology to improve the outcomes of patients affected by kidney diseases with cost-effective interventions.

Background Issues related to renal replacement therapy in elderly people with end stage kidney disease (ESKD) are complex. There is inadequate empirical data related to: decision-making by older populations, treatment experiences, implications of dialysis treatment and treatment modality on quality of life, and how these link to expectations of ageing. Study population Participants for this study were selected from a larger quantitative study of dialysis and predialysis patients aged 65 years or older recruited from three nephrology services across New Zealand. All participants had reached chronic kidney disease (CKD) stage 5 and had undergone dialysis education but had not started dialysis or recently started dialysis within the past 6 months. Methodology Serial qualitative interviews were undertaken to explore the decision-making processes and subsequent treatment experiences of patients with ESKD. Analytical approach: A framework method guided the iterative process of analysis. Decision-making codes were generated within NVivo software and then compared with the body of the interviews. Results Interviews were undertaken with 17 participants. We observed that decision-making was often a fluid process, rather than occurring at a single point in time, and was heavily influenced by perceptions of oneself as becoming old, social circumstances, life events and health status. Limitations This study focuses on participants' experiences of decision-making about treatment and does not include perspectives of their nephrologists or other members of the nephrology team. Conclusions Older patients often delay dialysis as an act of self-efficacy. They often do not commit to a dialysis decision following predialysis education. Delaying decision-making and initiating dialysis were common. This was not seen by participants as a final decision about therapy. Predialysis care and education should be different for older patients, who will delay decision-making until the time of facing obvious uraemic symptoms, threatening blood tests or paternalistic guidance from their nephrologist.

2015-01-01

Summary Although oncogene-targeted therapy often elicits profound initial tumor responses in patients, responses are generally incomplete because some tumor cells survive initial therapy as residual disease that enables eventual acquired resistance. The mechanisms underlying tumor cell adaptation and survival during initial therapy are incompletely understood. Here, through the study of EGFR-mutant lung adenocarcinoma we show that NF-κB signaling is rapidly engaged upon initial EGFR inhibitor treatment to promote tumor cell survival and residual disease. EGFR oncogene inhibition induced an EGFR-TRAF2-RIP1-IKK complex that stimulated an NF-κB-mediated transcriptional survival program. The direct NF-κB inhibitor PBS-1086 suppressed this adaptive survival program and increased the magnitude and duration of initial EGFR inhibitor response in multiple NSCLC models, including a patient-derived xenograft. These findings unveil NF-κB activation as a critical adaptive survival mechanism engaged by EGFR oncogene inhibition and provide rationale for EGFR and NF-κB co-inhibition to eliminate residual disease and enhance patient responses.

We report the clinical outcomes of patients who underwent percutaneous coronary intervention (PCI) with orbital atherectomy for severely calcified unprotected left main coronary artery (ULMCA) disease. Although surgical revascularization is the gold standard for patients with ULMCA disease, not all patients are candidates for this. PCI is increasingly used to treat complex coronary artery disease, including ULMCA disease. The presence of severely calcified lesions increases the complexity of PCI. Orbital atherectomy can be used to facilitate stent delivery and expansion in severely calcified lesions. The clinical outcomes of patients treated with orbital atherectomy for severely calcified ULMCA disease have not been reported. From May 2014 to July 2015, a total of 14 patients who underwent PCI with orbital atherectomy for ULMCA disease were retrospectively evaluated. The primary endpoint was major cardiac and cerebrovascular event (cardiac death, myocardial infarction, stroke, and target-lesion revascularization) at 30 days. The mean age was 78.2 ± 5.8 years. The mean ejection fraction was 41.8 ± 19.8%. Distal bifurcation disease was present in 9 of 14 patients. Procedural success was achieved in all 14 patients. The 30-day major adverse cardiac and cerebrovascular event rate was 0%. One patient had coronary dissection that was successfully treated with stenting. No patient had perforation, slow flow, or thrombosis. Orbital atherectomy in patients with severely calcified ULMCA disease is feasible, even in high-risk patients who were considered poor surgical candidates. Randomized trials are needed to determine the role of orbital atherectomy in ULMCA disease.

Depressive symptoms in neurodegenerative diseases

Depressive symptoms are very common in chronic conditions. This is true so for neurodegenerative diseases. A number of patients with cognitive decline and dementia due to Alzheimer’s disease and related conditions like Parkinson’s disease, Lewy body disease, vascular dementia, frontotemporal degeneration amongst other entities, experience depressive symptoms in greater or lesser grade at some point during the course of the illness. Depressive symptoms have a particular significance in neurological disorders, specially in neurodegenerative diseases, because brain, mind, behavior and mood relationship. A number of patients may develop depressive symptoms in early stages of the neurologic disease, occurring without clear presence of cognitive decline with only mild cognitive deterioration. Classically, depression constitutes a reliable diagnostic challenge in this setting. However, actually we can recognize and evaluate depressive, cognitive or motor symptoms of neurodegenerative disease in order to establish their clinical significance and to plan some therapeutic strategies. Depressive symptoms can appear also lately, when the neurodegenerative disease is fully developed. The presence of depression and other neuropsychiatric symptoms have a negative impact on the quality-of-life of patients and caregivers. Besides, patients with depressive symptoms also tend to further decrease function and reduce cognitive abilities and also uses to present more affected clinical status, compared with patients without depression. Depressive symptoms are treatable. Early detection of depressive symptoms is very important in patients with neurodegenerative disorders, in order to initiate the most adequate treatment. We review in this paper the main neurodegenerative diseases, focusing in depressive symptoms of each other entities and current recommendations of management and treatment. PMID:26301229

There is ample evidence demonstrating that the initiating events in obesity-induced inflammation start early in childhood. This has significant implications on our understanding of how early life events in childhood influence adult disease. In this Review we frame the initiating events of metainflammation in the context of child development and discuss what this reveals about the mechanisms by which this unique form of chronic inflammation is initiated and sustained into adulthood.

The burden of chronic diseases in global health is a surging area of research. The Global Health Initiative at the National Heart, Lung, and Blood Institute brings together investigators from developing countries with those from the developed world to study these diseases. In China, approximately 83 percent of all deaths in 2000 were attributed to chronic illnesses, which are the research focuses of the Chinese center of the Global Health Initiative. Tobacco use as well as passive smoking are modifiable risk factors in a large number of such chronic conditions. The prevalence of smoking in China is extensive and has inseparable ties to the economy, with tobacco taxes making up a large portion of government revenue in poorer provinces. Methods of smoking prevention have been piloted in some Chinese schools, which have mitigated the increase in smoking rate but have not resulted in a primary preventive effect. Efforts by the Yale Global Health Initiative and the Yale-China Association are bringing researchers together to address chronic disease in China as Yale School of Medicine enters its 200th year.

Integrated tuberculosis (TB) and human immunodeficiency virus (HIV) services in a resource-constrained setting. Pilot provider-initiated HIV testing and counselling (PITC) for TB patients and suspects. Through partnerships, resources were mobilised to establish and support services. After community sensitisation and staff training, PITC was introduced to TB patients and then to TB suspects from December 2003 to December 2005. Of 5457 TB suspects who received PITC, 89% underwent HIV testing. Although not statistically significant, TB suspects with TB disease had an HIV prevalence of 61% compared to 63% for those without. Of the 614 suspects who declined HIV testing, 402 (65%) had TB disease. Of 2283 patients referred for cotrimoxazole prophylaxis, 1951 (86%) were enrolled, and of 1727 patients assessed for antiretroviral treatment (ART), 1618 (94%) were eligible and 1441 (83%) started treatment. PITC represents a paradigm shift and is feasible and acceptable to TB patients and TB suspects. Clear directives are nevertheless required to change practice. When offered to TB suspects, PITC identifies large numbers of persons requiring HIV care. Community sensitisation, staff training, multitasking and access to HIV care contributed to a high acceptance of HIV testing. Kenya is using this experience to inform national response and advocate wide PITC implementation in settings faced with the TB-HIV epidemic.

Medical management of levodopa-associated motor complications in patients with Parkinson's disease.

PubMed

Jankovic, Joseph; Stacy, Mark

2007-01-01

Parkinson's disease is a neurodegenerative disorder that affects approximately 1% of people over the age of 60 years. Levodopa is standard, and often initial, therapy for patients with this condition; however, with continued treatment and as the disease progresses, up to 80% of patients experience 'wearing-off' symptoms, dyskinesias and other motor complications. These levodopa-associated problems may become disabling and profoundly affect quality of life. Medications commonly used to manage these symptoms include monoamine oxidase type B (MAO-B) inhibitors, catechol-O-methyltransferase (COMT) inhibitors, the NMDA receptor antagonist amantadine and dopamine receptor agonists. Agents that block MAO-B, such as rasagiline and selegiline, are used as both initial and adjunctive therapy in patients with Parkinson's disease. These medications increase concentrations of dopamine in the brain by blocking its reuptake from the synaptic cleft, a mechanism that can slow motor decline, increase 'on' time and improve symptoms of Parkinson's disease. Adverse events with these agents can include confusion, hallucination and orthostatic hypotension. MAO-B inhibition may elicit drug-drug interactions if administered with TCAs, SSRIs or SNRIs. Conventional oral selegiline is associated with potentially harmful plasma concentrations of three major amphetamine metabolites, although metabolite concentrations are significantly lower with a new orally disintegrating tablet (ODT) selegiline formulation. Selegiline ODT is also absorbed more efficiently and shows less pharmacokinetic variability than conventional oral selegiline.COMT mediates peripheral catabolism of levodopa. Therefore, agents that block COMT, such as tolcapone and entacapone, increase the elimination half-life of levodopa. Given adjunctively with levodopa, COMT inhibitors can decrease 'off' time and increase 'on' time, as well as lower the daily levodopa dose. Although more potent than entacapone, tolcapone requires monitoring for hepatotoxicity. Amantadine is a noncompetitive NMDA receptor antagonist shown to lower dyskinesia scores and improve motor complications in patients with Parkinson's disease when given adjunctively with levodopa. Dopamine agonists, also used as initial and adjunctive therapy in Parkinson's disease, improve motor response and decrease 'off' time purportedly through direct stimulation of dopamine receptors. Current dopamine agonists include bromocriptine, pergolide, cabergoline, lisuride, apomorphine, pramipexole, ropinirole and rotigotine. Although effective, this class of medications can be associated with cardiovascular and psychiatric adverse effects that can limit their utility. All medications used to manage levodopa-associated motor complications in patients with Parkinson's disease have had differing degrees of success. Although head-to-head comparisons of drugs within classes are rare, some differences have emerged related to effects on motor fluctuations, dyskinesias and on/off times, as well as to adverse effects. When choosing a drug to treat levodopa-induced complications, it is important to consider the risks and benefits of the different classes and of the specific agents within each class, given the different efficacy and safety profiles of each.

With a combined estimated prevalence of 3% in the general population, these conditions represent a relevant epidemiological entity worldwide, and are a major cause of cardiac morbidity and mortality in the young. The extraordinary progress achieved in molecular genetics over the last three decades has unveiled the complex molecular basis of many familial cardiac conditions, paving the way for routine use of gene testing in clinical practice. In current practice, genetic testing can be used in a clinically affected patient to confirm diagnosis, or to formulate a differential diagnosis among overlapping phenotypes or between hereditary and acquired (nongenetic) forms of disease. Although genotype-phenotype correlations are generally unpredictable, a precise molecular diagnosis can help predict prognosis in specific patient subsets and may guide management. In clinically unaffected relatives, genetic cascade testing is recommended, after the initial identification of a pathogenic variation, with the aim of identifying asymptomatic relatives who might be at risk of disease-related complications, including unexpected sudden cardiac death. Future implications include the identification of novel therapeutic targets and development of tailored treatments including gene therapy. This document reflects the multidisciplinary, 'real-world' experience required when implementing genetic testing in cardiomyopathies and arrhythmic syndromes, along the recommendations of various guidelines.

Background South Africa is facing a complex burden of disease arising from a combination of chronic infectious illness and non-communicable diseases. As the burden of chronic diseases (communicable and non-communicable) increases, providing affordable and effective care to the increasing numbers of chronic patients will be an immense challenge. Methods The framework recommended by the Medical Research Council of the United Kingdom for the development and evaluation of complex health interventions was used to conceptualise the intervention. The breakthrough series was utilised for the implementation process. These two frameworks were embedded within the clinical practice improvement model that served as the overarching framework for the development and implementation of the model. Results The Chronic Care Model was ideally suited to improve the facility component and patient experience; however, the deficiencies in other aspects of the health system building blocks necessitated a hybrid model. An integrated chronic disease management model using a health systems approach was initiated across 42 primary health care facilities. The interventions were implemented in a phased approach using learning sessions and action periods to introduce the planned and targeted changes. Conclusion The implementation of the integrated chronic disease management model is feasible at primary care in South Africa provided that systemic challenges and change management are addressed during the implementation process.

Systems biology approaches offer novel insights into the development of chronic liver diseases. Current genomic databases supporting systems biology analyses are mostly based on microarray data. Although these data often cover genome wide expression, the validity of single microarray experiments remains questionable. However, for systems biology approaches addressing the interactions of molecular networks comprehensive but also highly validated data are necessary. We have therefore generated the first comprehensive database for published molecular associations in human liver diseases. It is based on PubMed published abstracts and aimed to close the gap between genome wide coverage of low validity from microarray data and individual highly validated data from PubMed. After an initial text mining process, the extracted abstracts were all manually validated to confirm content and potential genetic associations and may therefore be highly trusted. All data were stored in a publicly available database, Library of Molecular Associations http://www.medicalgenomics.org/databases/loma/news, currently holding approximately 1260 confirmed molecular associations for chronic liver diseases such as HCC, CCC, liver fibrosis, NASH/fatty liver disease, AIH, PBC, and PSC. We furthermore transformed these data into a powerful resource for molecular liver research by connecting them to multiple biomedical information resources. Together, this database is the first available database providing a comprehensive view and analysis options for published molecular associations on multiple liver diseases.

Disease Management Evaluation: A Comprehensive Review of Current State of the Art.

2011-01-01

Many countries across Europe and elsewhere have been experimenting with various structured approaches to manage patients with chronic illness as a way to improve quality of care, reduce costs and lead to better population health outcomes in the long run. Despite a body of studies of disease management interventions, uncertainty about the effects of these remains not least because current guidance on evaluation methods and metrics require further development to enhance scientific rigour while also being practical in routine operations. This article provides details from a report that reviews the academic and grey literature to help advance the task of improving the science of assessing disease management initiatives in Europe. Challenges identified are methodological, analytical and conceptual in nature, with a key issue being the establishment of the counterfactual. An array of sophisticated statistical techniques and analytical frameworks can assist in the construction of a sound comparison strategy when a randomised controlled trial is not possible. Issues to consider include: a clear framework of the mechanisms of action and expected effects of disease management; an understanding of the characteristics of disease management (scope, content, dose, context), and of the intervention and target populations (disease type, severity, case-mix); a period of observation over multiple years; and a logical link between performance measures and the intervention's aims and underlying theory of behaviour change.

We performed a study to investigate the status of thyroid nodules and thyroid functions in Chinese breast cancer women. The clinical data of female patients with breast cancer or benign breast diseases and normal populace were evaluated. The thyroxine(T4) level in initially diagnosed breast cancer patients were significantly higher than those in benign breast diseases patients (7.68±1.51 vs 7.29±1.52ug/dl, p<0.001), while the TSH levels were slightly lower than in benign breast diseases patients(3.23±4.59 vs 3.60±6.74uIU/ml, p=0.302). The overall incidence of hypothyroidism in initially diagnosed breast cancer and benign breast diseases patients were 28.65% and 32.74%(p=0.195). During chemotherapy, the T4(7.08±1.69ug/dl), fT3(2.87±0.48pg/ml) and fT4(0.83±0.15ng/dl) levels were significantly lower than in initially diagnosed breast cancer patients(7.68±1.51ug/dl, 3.07±0.50pg/ml, 0.88±0.20ng/dl, p<0.05). The incidence of thyroid nodules in initially diagnosed breast cancer patients, benign breast diseases patients and healthy population were 56.17%, 43.64%, 34.49%(p<0.001). The incidence of TI-RADS≥4 TN in initially diagnosed breast cancer patients and benign breast diseases patients were significantly higher than in normal population(7.27% vs 9.45% vs 2.87%, p<0.001). The incidence of TI-RADS≥4 thyroid nodules in breast cancer patients receiving chemotherapy was significantly higher than in initially diagnosed breast cancer patients(11.71% vs 7.27%, p<0.05). These data indicate that the incidence of thyroid disease in breast disease patients is higher than in normal population in China, and the breast diseases, especially breast cancer, might be related to the high incidence of thyroid nodules.

A drug-use and disease-state management (DUDSM) program was instituted in 1996 at a teaching hospital associated with a large nonprofit health care system. The program's goals are to optimize pharmacotherapeutic regimens, evaluate health outcomes of identified disease states, and evaluate the economic impact of pharmacotherapeutic options for given disease states by developing practice guidelines. Through a re-engineering process, resources within the pharmacy department were identified that could be devoted to the DUDSM program, including the use of clinical pharmacy specialists, promotion of staff pharmacists into the DUDSM program, a pharmacy technician, and information systems support. A strength of the program is its systematic approach for developing and implementing new initiatives, as well as monitoring compliance with all initiatives on an ongoing basis. The initiative-design process incorporates continuous quality improvement principles, outcome design and evaluation, competency assessment for all pharmacists, multidisciplinary collaboration, and sophisticated information systems. Seventy-five initiatives have been implemented, ranging from simple dose-optimization strategies for specific drugs to complicated practice guidelines for managing specific disease states. Improved patient outcomes have been documented, including reduced length of stay, postsurgical wound infection, adverse drug reactions, and medication errors. Documented cost savings exceeded $4 million annually for fiscal years 1996-97 through 1999-2000. Overall compliance with DUDSM initiatives exceeds 80%, and physician service profiling has been initiated to monitor variant prescribing. The DUDSM program has successfully integrated practice guidelines into therapeutic decision-making, resulting in improved patient-care outcomes and cost savings.

Long-term effect of initiating pramipexole vs levodopa in early Parkinson disease.

2009-05-01

To compare the long-term outcomes of subjects initially treated with pramipexole dihydrochloride with those of subjects initially treated with levodopa in the Comparison of the Agonist Pramipexole With Levodopa on Motor Complications of Parkinson's Disease (CALM-PD) trial. Up to 2 years of open extended follow-up of the CALM-PD subjects. Academic movement disorders clinics at 22 sites in the United States and Canada. Patients Patients with early Parkinson disease (N = 301) who required dopaminergic therapy to treat emerging disability were enrolled between October 1996 and August 1997, a subset of whom consented to extended follow-up until August 2003 (n = 222). Intervention Subjects were randomized to receive initial treatment with either pramipexole (n = 151) or levodopa (n = 150). Investigators were permitted to add open-label levodopa or other antiparkinsonian medications to treat ongoing or emerging disability. The primary outcome variable was the time-weighted average of self-reported disability scores in the "on" and "off" states as measured by the Schwab and England Activities of Daily Living Scale at the final visit. Secondary outcomes included the Unified Parkinson's Disease Rating Scale score, the presence and severity of dopaminergic motor complications, quality-of-life scale scores, Geriatric Depression Scale score, Epworth Sleepiness Scale score, and adverse events. After a mean (SD) follow-up of 6.0 (0.2) years, mean (SD) self-reported weighted Schwab and England Activities of Daily Living Scale scores were similar in the initial pramipexole (79.9 [16.2]) and initial levodopa (82.5 [14.6]) groups (P = .19). Dopaminergic motor complications (wearing off, on-off effects, or dyskinesias) were more common in the initial levodopa group (68.4%) than in the initial pramipexole group (50.0%) (P = .002), although disabling dyskinesias were uncommon in both groups. The mean (SD) Epworth Sleepiness Scale score was significantly higher in the initial pramipexole group (11.3 [5.8]) than in the initial levodopa group (8.6 [4.7]) (P < .001). Mean (SD) changes from baseline in the total Unified Parkinson's Disease Rating Scale score did not significantly differ between the initial pramipexole (2.4 [17.4]) and initial levodopa (0.5 [17.1]) groups (P = .11). The policies of initial pramipexole and initial levodopa use followed by open-label levodopa use resulted in similar self-reported disability 6 years after randomization. Persistent differences favoring initial pramipexole were seen in the rates of dopaminergic motor complications, with less severe somnolence favoring initial levodopa.

Compliance to fingolimod and other disease modifying treatments in multiple sclerosis patients, a retrospective cohort study

PubMed Central

2013-01-01

Background Adherence to disease-modifying therapies (DMTs) results in the reduction of the number and severity of relapses and delays the progression of multiple sclerosis (MS). Patients with lower adherence rates experience more inpatient visits and higher MS-related medical costs. Fingolimod, the first oral DMT approved by the US Food and Drug Administration, may improve the access and compliance to MS treatment when compared to injectable DMTs. Methods This retrospective cohort study used pharmacy claims from Medco Health Solutions, Inc., of patients who initiated DMTs between October 2010 and February 2011. Initiation was defined as no prescription fills for the same DMT in the prior 12 months. Patients without a DMT prescription fill 12 months before the index date were considered naïve users. Compliance was measured via proportion of days covered (PDC) and medication possession ratio (MPR) for 12 months post-index. Discontinuation was defined as a ≥60-day gap of index DMT supply. Cox proportional hazard models compared time to discontinuation between cohorts. Results Of 1,891 MS patients (mean age: 45.7; female: 76.4%), 13.1% initiated fingolimod, 10.7% interferon beta-1b, 20.0% intramuscular interferon beta-1a, 18.8% subcutaneous interferon beta-1a, and 37.4% glatiramer acetate. Patients initiating fingolimod had highest average PDC and MPR in both experienced (fingolimod: mean PDC=0.83, 73.7% with PDC≥0.8; mean MPR=0.92, 90.5% with MPR≥0.8) and naïve DMT users (fingolimod: mean PDC=0.80, 66.7% with PDC≥0.8; mean MPR=0.90, 87.4% with MPR≥0.8). The proportion of patients discontinuing index DMT within 12 months was significantly lower for the fingolimod cohort (naïve: 31.3%; experienced: 25.7%). Adjusted results found that patients receiving self-injected DMTs discontinued significantly sooner than fingolimod users. This association was generally stronger in experienced DMT users. Conclusions Fingolimod initiators were more compliant, less likely to discontinue treatment, and discontinued later than patients who initiated self-injected DMT. PMID:24093542

The pathological and physiological defects in various types of fruits lead to large amounts of economical waste. It is well recognized that internal fruit defects due to pathological infections and physiological disorders can be effectively visualized at an initial stage of the disease using a well-known bio-photonic detection method called optical coherence tomography (OCT). This work investigates the use of OCT for identifying the morphological variations of anthracnose (bitter rot) disease infected and physiologically disordered Diospyros kaki (Asian Persimmon) fruits. An experiment was conducted using fruit samples that were carefully selected from persimmon orchards. Depth-resolved images with a high axial resolution were acquired using 850-nm-based spectral-domain OCT (SD-OCT) system. The obtained exemplary high-resolution two-dimensional and volumetric three-dimensional images revealed complementary morphological differences between healthy and defected samples. Moreover, the obtained depth-profile analysis results confirmed the disappearance of the healthy cell layers among the healthy-infected boundary regions. Thus, the proposed method has the potential to increase the diagnostic accuracy of the OCT technique used in agricultural plantations.

Developmental Origins, Epigenetics, and Equity: Moving Upstream.

PubMed

Wallack, Lawrence; Thornburg, Kent

2016-05-01

The Developmental Origins of Health and Disease and the related science of epigenetics redefines the meaning of what constitutes upstream approaches to significant social and public health problems. An increasingly frequent concept being expressed is "When it comes to your health, your zip code may be more important than your genetic code". Epigenetics explains how the environment-our zip code-literally gets under our skin, creates biological changes that increase our vulnerability for disease, and even children's prospects for social success, over their life course and into future generations. This science requires us to rethink where disease comes from and the best way to promote health. It identifies the most fundamental social equity issue in our society: that initial social and biological disadvantage, established even prior to birth, and linked to the social experience of prior generations, is made worse by adverse environments throughout the life course. But at the same time, it provides hope because it tells us that a concerted focus on using public policy to improve our social, physical, and economic environments can ultimately change our biology and the trajectory of health and social success into future generations.

After the launch of the US President's Emergency Plan for AIDS Relief in 2003, it became evident that inadequate laboratory systems and services would severely limit the scale-up of human immunodeficiency virus infection prevention, care, and treatment programs. Thus, the Office of the US Global AIDS Coordinator, Centers for Disease Control and Prevention, and Becton, Dickinson and Company developed a public-private partnership (PPP). Between October 2007 and July 2012, the PPP combined the competencies of the public and private sectors to boost sustainable laboratory systems and develop workforce skills in 4 African countries. Key accomplishments of the initiative include measurable and scalable outcomes to strengthen national capacities to build technical skills, develop sample referral networks, map disease prevalence, support evidence-based health programming, and drive continuous quality improvement in laboratories. This report details lessons learned from our experience and a series of recommendations on how to achieve successful PPPs. © The Author 2016.

2001-01-01

This study examined the efficacy of 3D-fresh blood imaging (FBI) in patients with venous disease in the iliac region to lower extremity. Fourteen patients with venous disease were examined [8 deep venous thrombosis (DVT) and 6 varix] by 3D-FBI and 2D-TOF MRA. All FBI images and 2D-TOF images were evaluated in terms of visualization of the disease and compared with conventional X-ray venography (CV). The total scan time of 3D-FBI ranged from 3 min 24 sec to 4 min 52 sec. 3D-FBI was positive in all 23 anatomical levels in which DVT was diagnosed by CV (100% sensitivity) as well as 2D-TOF. The delineation of collateral veins was superior or equal to that of 2D-TOF. 3D-FBI allowed depiction of varices in five of six cases; however, in one case, the evaluation was limited because the separation of arteries from veins was difficult. The 3D-FBI technique, which allows iliac to peripheral MR venography without contrast medium within a short acquisition time, is considered clinically useful.

Outsourcing of Academic Clinical Laboratories

2018-01-01

American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.

Alzheimer's disease pathology begins decades before the onset of clinical symptoms. This provides an opportunity for interventional clinical trials to potentially delay or prevent the onset of cognitive impairment or dementia. CNP520 (a beta-site-amyloid precursor protein-cleaving enzyme inhibitor) is in clinical development for the treatment of preclinical Alzheimer's disease under the Alzheimer's Prevention Initiative Generation Program. The Alzheimer's Prevention Initiative is a public-private partnership intended to accelerate the evaluation of Alzheimer's disease prevention therapies. The Generation Program comprises two pivotal phase II/III studies with similar designs to assess the efficacy and safety of investigational treatments in a cognitively unimpaired population at increased risk for developing Alzheimer's disease based on age and apolipoprotein E (APOE) genotype (i.e., presence of the APOE ε4 allele). The program has been designed to maximize benefit to Alzheimer's disease research. Generation Study 1 (NCT02565511) and Generation Study 2 (NCT03131453) are currently enrolling; their key features are presented here.

2017-12-01

A major epidemiological finding emerging from studies using U.S. samples is that racial differences in experiences of discrimination are associated with racial differences in health. A newer area of research is exploring the population-level dynamics between race, discrimination, and health status in various societies. The objective of this study is to assess for the first time in a national sample from Canada: (a) racial differences in experiences of discrimination and, (b) the association between discrimination and chronic conditions and their major risk factors. Data were obtained from the 2013 Canadian Community Health Survey (n = 16,836). Race was categorized as Aboriginal, Asian, Black, or White. Discrimination was measured using the Williams Everyday Discrimination Scale. Outcomes included having any chronic condition or major risk factors (obesity, hypertension, smoking, binge drinking, infrequent physical activity, and poor self-rated health). Crude and adjusted (for age, sex, immigrant status, socioeconomics) logistic regressions modeled the association between (a) race and discrimination and, (b) discrimination and each outcome. Results indicated that Blacks were most likely to experience discrimination, followed by Aboriginals. For example, Blacks were almost twice as likely (OR: 1.92, 95% CI: 1.19-3.11), and Aboriginals 75 percent more likely (OR: 1.75, 95% CI: 1.37-2.22) to report being treated with less courtesy or respect than others. Blacks were more than four times as likely (OR: 4.27, 95% CI: 2.23-8.19), and Aboriginals more than twice as likely (OR: 2.26, 95% CI: 1.66-3.08) to report being feared by others. Asians were not statistically different from Whites. With two exceptions (binge drinking and physical activity), discrimination was associated with chronic conditions and their risk factors (OR for any chronic condition: 1.78, 95% CI: 1.52-2.08). Initial results suggest that in Canada, experience of discrimination is a determinant of chronic disease and chronic disease risk factors, and Blacks and Aboriginals are far more exposed to experiences of discrimination.

Rare neurological diseases: a Pandora's box for neurology (an European and Italian perspective).

PubMed

Federico, A

2013-02-01

Rare neurological diseases are a heterogeneous group of disorders mainly affecting the central and peripheral nervous systems and muscle, representing almost 50% of all rare diseases; this means that neurologists are among the main specialists involved in their diagnosis and research. However, the classical interest of neurologists is primarily directed towards the more common diseases such as dementia, multiple sclerosis, headache, epilepsy and stroke, while avoiding the follow-up of rare neurological diseases that have, taken altogether, had such a major impact on health systems in Europe as well as in other countries around the world. Rare diseases are also considered 'orphan' diseases, as only a few of them have treatments. In Europe as in the USA in recent years, considerable interest has been generated by these disorders, thereby stimulating more specific programs of care and management. In fact, the difficulty of diagnosis and the need for super-specialization in this field has led to the organization of dedicated centers in different countries to collect patients' data within a network for diagnosis, treatment and research. The present report describes our experience in Siena with such a reference center for these disorders and their diagnosis and treatment, and also includes a discussion of the organization of care for rare neurological diseases in Europe and Italy. Finally, this report also covers the new initiative of the Italian Neurological Society to promote an information center for rare neurological diseases to disseminate information and knowledge to all neurologists working in this field.

To evaluate the influence of temperature and humidity on the drug stability by initial average rate experiment, and to obtained the kinetic parameters. The effect of concentration error, drug degradation extent, humidity and temperature numbers, humidity and temperature range, and average humidity and temperature on the accuracy and precision of kinetic parameters in the initial average rate experiment was explored. The stability of vitamin C, as a solid state model, was investigated by an initial average rate experiment. Under the same experimental conditions, the kinetic parameters obtained from this proposed method were comparable to those from classical isothermal experiment at constant humidity. The estimates were more accurate and precise by controlling the extent of drug degradation, changing humidity and temperature range, or by setting the average temperature closer to room temperature. Compared with isothermal experiments at constant humidity, our proposed method saves time, labor, and materials.

In up to 10% of patients who experience abdominal trauma, renal and urogenital systems will be involved. In polytrauma patients with other potentially life-threatening injuries, renal and genitourinary trauma may be overlooked initially, but a delayed or missed diagnosis of these injuries may result in preventable complications. This review provides a best-practice approach to the diagnosis and management of renal and genitourinary injuries, with an emphasis on the systematic approach needed to identify subtle injuries and avoid long-term urinary sequelae such as hypertension, incontinence, erectile dysfunction, chronic kidney disease, and nephrectomy.

Oncology patients undergoing treatment can experience substantial pain related to their disease or prescribed therapy. Ketamine infusions at subanesthetic doses have been used at our institution to supplement the pain management regimens of 262 patients. We present 2 cases in which young adult patients being treated with subanesthetic ketamine for cancer-related pain experienced urinary urgency and incontinence after initiation or increase of the ketamine infusion. This adverse effect has not been reported previously at this dosing range. These case reports suggest that subanesthetic ketamine infusions may cause side effects that previously have been reported only at anesthetic or abuse doses.

Contemporary concepts in management of acute otitis media in children.

PubMed

Rettig, Eleni; Tunkel, David E

2014-10-01

Acute otitis media (AOM) is a common disease of childhood. AOM is most appropriately diagnosed by careful otoscopy with an understanding of clinical signs and symptoms. The distinction between AOM and chronic otitis media with effusion should be emphasized. Treatment should include pain management, and initial antibiotic treatment should be given to those most likely to benefit, including young children, children with severe symptoms, and those with otorrhea and/or bilateral AOM. Tympanostomy tube placement may be helpful for those who experience frequent episodes of AOM or fail medical therapy. Recent practice guidelines may assist the clinician with such decisions.

2010-11-01

Adrenal insufficiency is a rare disease caused by either primary adrenal failure (Addison disease) or by impairment of the hypothalamic-pituitary-adrenal axis. Steroid replacement therapy normalises quality of life, however, adherence can be problematic. This article provides information on adrenal insufficiency focusing on awareness of initial symptoms and on risk scenarios, emergency management and baseline investigations, complete investigations and long term management. Early recognition of adrenal insufficiency is essential to avoid associated morbidity and mortality. Initial diagnosis and decision to treat are based on history and physical examination. Appropriate management includes emergency resuscitation and steroid administration. Initial investigations can include sodium, potassium and blood glucose levels. However, complete investigations can be deferred. Specialist advice should be obtained and long term management includes a Team Care Arrangement. For patients, an emergency plan and emergency identification are essential.

Background: Impulse control disorder is not uncommon in patients with Parkinson’s disease (PD) who are treated with dopamine replacement therapy and subthalamic deep brain stimulation (DBS). Internal globus pallidus (GPi)-DBS is increasingly used, but its role in inhibitory control has rarely been explored. In this study, we evaluated the effect of GPi-DBS on inhibitory control in PD patients. Methods: A stop-signal paradigm was used to test response initiation, proactive inhibition, and reactive inhibition. The subjects enrolled in the experiment were 27 patients with PD, of whom 13 had received only drug treatment and 14 had received bilateral GPi-DBS in addition to conventional medical treatment and 15 healthy individuals. Results: Our results revealed that with GPi-DBS on, patients with PD showed significantly faster responses than the other groups in trials where it was certain that no stop signal would be presented. Proactive inhibition was significantly different in the surgical patients with GPi-DBS on versus when GPi-DBS was off, in surgical patients with GPi-DBS on versus drug-treated patients, and in healthy controls versus drug-treated patients. Correlation analyses revealed that when GPi-DBS was on, there was a statistically significant moderate positive relationship between proactive inhibition and dopaminergic medication. Conclusion: GPi-DBS may lead to an increase in response initiation speed and improve the dysfunctional proactive inhibitory control observed in PD patients. Our results may help us to understand the role of the GPi in cortical-basal ganglia circuits. PMID:29681869

Lupus erythematosus (LE) is an autoimmune disease which may initially present solely with lip lesions. Due to a wide spectrum of presentation, these features may initially be misdiagnosed as other oral diseases such as lichen planus, erythema multiforme (EM), and actinic cheilitis, leading to a delay in diagnosis and treatment. We discuss a case of severely crusted cheilitis which was initially diagnosed as EM, with subsequent development of subacute cutaneous LE, and progression to systemic LE. We will discuss the clinical and histological features of lupus cheilitis.

A workshop sponsored by the Human Toxicology Project Consortium (HTPC), "Building Shared Experience to Advance Practical Application of Pathway-Based Toxicology: Liver Toxicity Mode-of-Action" brought together experts from a wide range of perspectives to inform the process of pathway development and to advance two prototype pathways initially developed by the European Commission Joint Research Center (JRC): liver-specific fibrosis and steatosis. The first half of the workshop focused on the theory and practice of pathway development; the second on liver disease and the two prototype pathways. Participants agreed pathway development is extremely useful for organizing information and found that focusing the theoretical discussion on a specific AOP is extremely helpful. In addition, it is important to include several perspectives during pathway development, including information specialists, pathologists, human health and environmental risk assessors, and chemical and product manufacturers, to ensure the biology is well captured and end use is considered.

Synovitis assessment through evaluation of swollen joints is integral in steering treatment decisions in rheumatoid arthritis (RA). However, there is high inter-observer variation. The objective was to assess if a short collegiate consensus would improve swollen joint agreement between rheumatologists and whether this was affected by experience. Eighteen rheumatologists from French university rheumatology units participated in three 30 minutes rounds over a half day meeting evaluating joint counts of RA patients in small groups, followed by short consensus discussions. Agreement was evaluated at the end of each round as follows: (i) global agreement of swollen joints (ii) swollen joint agreement according to level of experience of the rheumatologist (iii) swollen joint count and (iv) agreement of disease activity state according to the Disease Activity Score (DAS28). Agreement was calculated using percentage agreement and kappa. Global agreement of swollen joints failed to improve (kappa 0.50 to 0.52) at the joint level. Agreement between seniors did not improve but agreement between newly qualified rheumatologists and their senior peer, which was initially poor (kappa 0.28), improved significantly (to 0.54) at the end of the consensus exercises. Concordance of DAS28 activity states improved from 71% to 87%. Consensus exercises for swollen joint assessment is worthwhile and may potentially improve agreement between clinicians in clinical synovitis and disease activity state, benefit was mostly observed in newly qualified rheumatologists.

In outbreaks of infectious disease, medical students are easily overlooked in the management of healthcare personnel protection although they serve in clinical clerkships in hospitals. In the early summer of 2015, Middle East respiratory syndrome (MERS) struck South Korea, and students of Sungkyunkwan University School of Medicine (SKKUSOM) were at risk of contracting the disease. The purpose of this report is to share SKKUSOM's experience against the MERS outbreak and provide suggestions for medical schools to consider in the face of similar challenges. Through a process of reflection-on-action, we examined SKKUSOM's efforts to avoid student infection during the MERS outbreak and derived a few practical guidelines that medical schools can adopt to ensure student safety in outbreaks of infectious disease. The school leadership conducted ongoing risk assessment and developed contingency plans to balance student safety and continuity in medical education. They rearranged the clerkships to another hospital and offered distant lectures and tutorials. Five suggestions are extracted for medical schools to consider in infection outbreaks: instant cessation of clinical clerkships; rational decision making on a school closure; use of information technology; constant communication with hospitals; and open communication with faculty, staff, and students. Medical schools need to take the initiative and actively seek countermeasures against student infection. It is essential that medical schools keep constant communication with their index hospitals and the involved personnel. In order to assure student learning, medical schools may consider offering distant education with online technology.

To describe the challenges, including sociocultural and socioeconomic barriers, faced by an urban immigrant population in the United States affected by thalassemia major. Ethnographic, semi-structured, 1-on-1 interviews using an interview guide developed for this study. Digital recordings were transcribed and data analyzed using constant comparative method. University-based, Comprehensive Thalassemia Program at Children's Memorial Hospital, Chicago, IL, USA. Fourteen Southeast Asian and Asian Indian parents of children with transfusion dependent thalassemia. Qualitative descriptions of parental experiences, frequency of codes applied to interviews and emergent themes. Thalassemia has its greatest impact on the emotional and social well-being of affected children and their parents. Current and future concerns were related to disease-specific complications and challenges with management such as transfusions and chelation therapy. These perceptions were tied to parental hope for a cure, a frequently coded coping mechanism. Despite their availability, few parents relied on support systems beyond immediate family members due to perceived public knowledge gaps about thalassemia. Culturally based past experiences and barriers did not emerge as dominant themes in our analysis. The impact of thalassemia is tremendous for affected children and their parents and is due more to factors that were either disease-specific or common to other chronic disease models rather than those influenced by culture. The unmet needs of these families require additional investigation to facilitate the development of initiatives aimed at improving quality of life and lessening overall impact of thalassemia

Miglustat therapy in the French cohort of paediatric patients with Niemann-Pick disease type C

PubMed Central

2012-01-01

Background Niemann-Pick disease type C (NP-C) is a rare neurovisceral lysosomal lipid storage disease characterized by progressive neurological deterioration. Published data on the use of miglustat in paediatric patients in clinical practice settings are limited. We report findings from a prospective open-label study in the French paediatric NP-C cohort. Methods Data on all paediatric NP-C patients treated with miglustat in France between October 2006 and December 2010 were compiled. All patients had a confirmed diagnosis of NP-C, and received miglustat therapy according to manufacturer’s recommendations. Pre-treatment and follow-up assessments were conducted according to a standardized protocol. Results Twenty children were enrolled; 19 had NPC1 gene mutations and 1 had NPC2 gene mutations. The median age at diagnosis was 1.5 years, and the median age at miglustat initiation was 6.0 years. Eight NPC1 patients had the early-infantile, eight had the late-infantile, and three had the juvenile-onset forms of NP-C. A history of hepatosplenomegaly and/or other cholestatic symptoms was recorded in all 8 early-infantile onset patients, 3/8 late-infantile patients, and 1/3 juvenile onset patients. Brain imaging indicated white matter abnormalities in most patients. The median (range) duration of miglustat therapy was 1.3 (0.6–2.3) years in early-infantile, 1.0 (0.8–5.0) year in late-infantile, and 1.0 (0.6–2.5) year in juvenile onset patients. NP-C disability scale scores indicated either stabilization or improvement of neurological manifestations in 1/8, 6/8, and 1/3 NPC1 patients in these subgroups, respectively. There were no correlations between brain imaging findings and disease course. Mild-to-moderate gastrointestinal disturbances were frequent during the first 3 months of miglustat therapy, but were easily managed with dietary modifications and/or anti-propulsive medication. Conclusions Miglustat can improve or stabilize neurological manifestations in paediatric patients with the late-infantile and juvenile-onset forms of NP-C. Among early-infantile onset patients, a shorter delay between neurological disease onset and miglustat initiation was associated with an initial better therapeutic outcome in one patient, but miglustat did not seem to modify overall disease course in this subgroup. More experience is required with long-term miglustat therapy in early-infantile onset patients treated from the very beginning of neurological manifestations. PMID:22676771

To assess the disease-related impairments of children with lymphatic malformations of the head and neck and their changes after therapy using the Cologne Disease Score (CDS). 29 children with lymphatic malformations of the head and neck were evaluated regarding their symptoms before and after therapy using the CDS. The Wilcoxon test for dependent groups was used to compare the CDS at initial visit before treatment and last visit after treatment. The CDS of patients belonging to the moderate (initial CDS: more than eight points) and advanced disease group (initial CDS: five, six or seven points) significantly increased after therapy while the patients in the severe disease group (initial CDS: lower than four points) showed no significant improvement of CDS. Patients with stage IV and especially stage V lymphatic malformations according to de Serres showed considerably lower pre- and posttherapeutic CDS levels than those of stage I and II. The visual impairment is not mapped by the CDS, therefore item vision should be added to the CDS to make an evaluation of all lymphatic malformations of the head and neck possible. The present series could show that especially patients with a moderate or advanced disease according to the CDS may profit from therapeutic interventions.

Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease (CVD) events, and a number of reports have shown a relationship between CKD and CVD in pre-dialysis or maintenance dialysis patients. However, few studies have reported serial observations during dialysis initiation and maintenance. Therefore, we examined whether the incidence of heart disease events differed between CKD patients with and without a history of coronary heart disease (CHD) at dialysis initiation. The subjects were patients in the 17 centers participating in the Aichi Cohort Study of Prognosis in Patients Newly Initiated into Dialysis (AICOPP) from October 2011 to September 2013. We excluded nine patients whose outcomes were unknown, as determined by a survey conducted at the end of March 2015. Thus, we enrolled 1,515 subjects into the study. We classified patients into 2 groups according to the history of CHD (i.e., a CHD group and a non-CHD group). Propensity scores (PS) represented the probability of being assigned to a group with or without a history of CHD. Onset of heart disease events and associated mortality and all-cause mortality were compared in PS-matched patients by using the log-rank test for Kaplan-Meier curves. Factors contributing to heart disease events were examined using stepwise multivariate Cox proportional hazards analysis. There were 254 patients in each group after PS-matching. During observation, heart disease events occurred in 85 patients (33.5%) in the CHD group and 48 (18.9%) patients in the non-CHD group. The incidence was significantly higher in the CHD group (p < 0.0001). The CHD group was associated with higher incidence of heart disease events (vs. the non-CHD group, hazard ratio = 1.750, 95% confidence interval = 1.160-2.639). In addition, comorbidities such as diabetes mellitus, low body mass index, and low serum high-density lipoprotein cholesterol were associated with higher incidence of events. History of CHD at dialysis initiation was associated with a higher incidence of heart disease events and mortality and all-cause mortality. UMIN 000007096 . Registered 18 January 2012.

Although brain neuroinflammation may play an instrumental role in the pathophysiology of Alzheimer's disease, its actual impact on disease progression remains controversial, being reported as either detrimental or protective. This work aimed at investigating the temporal relationship between microglial activation and clinical progression of Alzheimer's disease. First, in a large cohort of patients with Alzheimer's disease we analysed the predictive value of microglial activation assessed by 18F-DPA-714 PET imaging on functional, cognitive and MRI biomarkers outcomes after a 2-year follow-up. Second, we analysed the longitudinal progression of 18F-DPA-714 binding in patients with Alzheimer's disease by comparison with controls, and assessed its influence on clinical progression. At baseline, all participants underwent a clinical assessment, brain MRI, 11C-PiB, 18F-DPA-714 PET imaging and TSPO genotyping. Participants were followed-up annually for 2 years. At the end of the study, subjects were asked to repeat a second 18F-DPA-714-PET imaging. Initial 18F-DPA-714 binding was higher in prodromal (n = 33) and in demented patients with Alzheimer's disease (n = 19) compared to controls (n = 17). After classifying patients into slow and fast decliners according to functional (Clinical Dementia Rating change) or cognitive (Mini-Mental State Examination score decline) outcomes, we found a higher initial 18F-DPA-714 binding in slow than fast decliners. Negative correlations were observed between initial 18F-DPA-714 binding and the Clinical Dementia Rating Sum of Boxes score increase, the MMSE score loss and the progression of hippocampal atrophy. This suggests that higher initial 18F-DPA-714 binding is associated with better clinical prognosis. Twenty-four patients with Alzheimer's disease and 15 control subjects performed a second DPA-PET. We observed an increase of 18F-DPA-714 in patients with Alzheimer's disease as compared with controls (mean 13.2% per year versus 4.2%) both at the prodromal (15.8%) and at the demented stages (8.3%). The positive correlations between change in 18F-DPA-714 binding over time and the three clinical outcome measures (Clinical Dementia Rating, Mini-Mental State Examination, hippocampal atrophy) suggested a detrimental effect on clinical Alzheimer's disease progression of increased neuroinflammation after the initial PET examination, without correlation with PiB-PET uptake at baseline. High initial 18F-DPA-714 binding was correlated with a low subsequent increase of microglial activation and favourable clinical evolution, whereas the opposite profile was observed when initial 18F-DPA-714 binding was low, independently of disease severity at baseline. Taken together, our results support a pathophysiological model involving two distinct profiles of microglial activation signatures with different dynamics, which differentially impact on disease progression and may vary depending on patients rather than disease stages.

Introduction Malignant tumors of the paranasal sinuses are traditionally managed through external approaches. Advances in endoscopic transnasal surgery have allowed for the endoscopic treatment of some of these tumors. Aim To present the results of treatment of a series of patients with paranasal sinus malignancies treated with an endoscopic approach at a single institution. Material and methods The data on tumor type, operative technique, perioperative complications and postoperative course were analyzed. Results Eleven patients meeting the inclusion criteria were identified. The histopathology was as follows: malignant melanoma in 3 patients, squamous cell carcinoma in 2, adenocarcinoma in 2, poorly differentiated carcinoma in 1, hemangiopericytoma in 1, adenoid cystic carcinoma in 1 and fibrosarcoma in 1. There were no severe perioperative complications with the exception of 1 case of cerebrospinal fluid leak, which was successfully closed. The mean observation period was 13.5 months. One of the patients died of disease, another was lost to follow-up, and one was reoperated on due to recurrence. The remaining 8 patients are alive with no signs of recurrence. Conclusions Our initial experience seems to confirm results obtained by other authors indicating that in selected cases endoscopic surgery of sinonasal malignancies is similarly effective as external approach surgery.

Objectives Global health research into the relationship between health, economic inequalities, and globalization is necessary to address increasing health disparities in low income countries. Nicaragua has high levels of poverty and extreme poverty when compared with other Central and South American Countries. Design Photovoice and ethnographic research methods were used to explore health experiences of Creole women in Bluefields, Nicaragua and the intersections between culture, socioeconomic status, and gender. Sample Twelve Creole women participants, ages 18–45. Measurements After initial focus groups, participants used disposable cameras to document health experiences. Follow up interviews were conducted about the meaning of each photo. Participants then selected photos to be included in a city-wide photoshow. Results In initial focus groups, participants described great distress over changes they perceived in Creole culture and how these changes affect the health of the next generation. Participants related most of these changes to the economy and globalization. Photos taken were primarily of aspects of Creole culture, including household practices and traditional remedies from Creole culture. Conclusions Findings on the relationships between culture, disease and community-identified health risks in this minority population can help healthcare providers and public health policy makers develop and sustain culturally appropriate health interventions.

The transfemoral approach is a common technique for coil embolization of cerebral aneurysms in the anterior cerebral circulation. However, it is difficult to advance a guiding catheter into the carotid artery via the femoral route in patients with a tortuous aortic arch, an unfavorable supra-aortic takeoff, aortic diseases, or occlusion of the femoral artery. To report our initial experiences of coil embolization of cerebral aneurysms in the anterior cerebral circulation with a novel sheath guide for transbrachial carotid cannulation. A sheath guide designed specifically for transbrachial carotid cannulation was developed; transbrachial coil embolization for cerebral aneurysms began in May 2011. Included for analysis were patients who underwent transbrachial coil embolization for cerebral aneurysms in the anterior cerebral circulation from May 2011 to January 2012. Adjuvant techniques, angiographic results, procedural success, and periprocedural complications were investigated. Ten patients underwent transbrachial coil embolization of cerebral aneurysms in the anterior cerebral circulation. All procedures were successful using the brachial route. No periprocedural complications occurred. Patients were permitted to get seated immediately after coil embolization even during hemostasis. The sheath guide specifically designed for transbrachial carotid cannulation was useful for coil embolization of cerebral aneurysms in the anterior cerebral circulation.

Falls and dementia are two major public health problems which concern the elderly population. Cognitive impairment, as a result of Alzheimer's disease or non-Alzheimer dementia, is recognized as a risk factor for falling. Through the experience of the Multidisciplinary Falls Consultation, our aims were first, to evaluate the prevalence of a cognitive decline among outpatients who consult for falls, and second, to determine whether the cognitive impairment was known and diagnosed before the consultation or not. Data concerning the first 300 outpatients who completed the initial evaluation are reported. Each patient was assessed by a geriatrician, a neurologist, and a physiatrist, who visited him or her at home. Cognitive impairment was defined as a Mini-Mental State Examination (MMSE) score<24. Of the 300 patients, 228 patients completed the initial evaluation. Among them, 97 (42.5 percent) had a MMSE score<24; 55 had mild stage dementia (MMSE score between 23 and 18) and 42 were at a moderate or severe stage (MMSE score< or =17/30). The cognitive decline was not diagnosed before the consultation in 80 of the 97 patients (82 percent). The findings show that a large proportion of old persons presenting with gait disturbance at the Multidisciplinary Falls Consultation have an underlying cognitive decline. Assessment of cognitive functions is required in every elderly faller.

Flavonoid-Based Therapies in the Early Management of Neurodegenerative Diseases12

During the past several years, there has been enormous progress in the understanding of the causative factors that initiate neuronal damage in various neurodegenerative diseases, including Alzheimer disease, Parkinson disease, multiple sclerosis, amyotrophic lateral sclerosis, and Huntington disease. Preventing neuronal damage and neuronal death will have a huge clinical benefit. However, despite major advances in causative factors that trigger these neurodegenerative diseases, to date there have been no therapies available that benefit patients who suffer from these diseases. Because most neurodegenerative diseases are late-onset and remain asymptomatic for most of the phases, the therapies initiated in advanced stages of the disease have limited value to patients. It may be possible to prevent or halt the disease progression to a great extent if therapies start at the initial stage of the disease. Such therapies may restore neuronal function by reducing or even eliminating the primary stressor. Flavonoids are key compounds for the development of a new generation of therapeutic agents that are clinically effective in treating neurodegenerative diseases. Regular consumption of flavonoids has been associated with a reduced risk of neurodegenerative diseases. In addition to their antioxidant properties, these polyphenolic compounds exhibit neuroprotective properties by their interaction with cellular signaling pathways followed by transcription and translation that mediate cell function under both normal and pathologic conditions. This review focuses on human intervention studies as well as animal studies on the role of various flavonoids in the prevention of neurodegenerative diseases. PMID:25593144

2016-11-01

We describe experiments of single-shock Richtmyer-Meskhov Instability (RMI) performed on the shock tube apparatus at the University of Arizona in which the initial conditions are volumetrically imaged prior to shock wave arrival. Initial perturbations play a major role in the evolution of RMI, and previous experimental efforts only capture a single plane of the initial condition. The method presented uses a rastered laser sheet to capture additional images throughout the depth of the initial condition immediately before the shock arrival time. These images are then used to reconstruct a volumetric approximation of the experimental perturbation. Analysis of the initial perturbations is performed, and then used as initial conditions in simulations using the hydrodynamics code ARES, developed at Lawrence Livermore National Laboratory (LLNL). Experiments are presented and comparisons are made with simulation results.

Objective To determine the incidence and impact of recurrent workplace injury and disease over the period 1995–2008. Design Population-based cohort study using data from the state workers’ compensation system database. Setting State of Victoria, Australia. Participants A total of 448 868 workers with an accepted workers’ compensation claim between 1 January 1995 and 31 December 2008 were included into this study. Of them, 135 349 had at least one subsequent claim accepted for a recurrent injury or disease during this period. Main outcome measures Incidence of initial and recurrent injury and disease claims and time lost from work for initial and recurrent injury and disease. Results Over the study period, 448 868 workers lodged 972 281 claims for discrete occurrences of work-related injury or disease. 53.4% of these claims were for recurrent injury or disease. On average, the rates of initial claims dropped by 5.6%, 95% CI (−5.8% to −5.7%) per annum, while the rates of recurrent injuries decreased by 4.1%, 95% CI (−4.2% to −0.4%). In total, workplace injury and disease resulted in 188 978 years of loss in full-time work, with 104 556 of them being for the recurrent injury. Conclusions Recurrent work-related injury and disease is associated with a substantial social and economic impact. There is an opportunity to reduce the social, health and economic burden of workplace injury by enacting secondary prevention programmes targeted at workers who have incurred an initial occupational injury or disease.

Immediately recalling a witnessed event can increase people's susceptibility to later postevent misinformation. But this retrieval-enhanced suggestibility (RES) effect has been shown only when the initial recall test included specific questions that reappeared on the final test. Moreover, it is unclear whether this phenomenon is affected by the centrality of event details. These limitations make it difficult to generalize RES to criminal investigations, which often begin with free recall prior to more specific queries from legal officials and attorneys. In 3 experiments, we examined the influence of test formats (free recall vs. cued recall) and centrality of event details (central vs. peripheral) on RES. In Experiment 1, both the initial and final tests were cued recall. In Experiment 2, the initial test was free recall and the final test was cued recall. In Experiment 3, both the initial and final tests were free recall. Initial testing increased misinformation reporting on the final test for peripheral details in all experiments, but the effect was significant for central details only after aggregating the data from all 3 experiments. These results show that initial free recall can produce RES, and more broadly, that free recall can potentiate subsequent learning of complex prose materials. © 2013 American Psychological Association

Delay in diagnosis of pancreatic ductal adenocarcinoma (PDAC) is associated with decreased survival. The effect of an initial misdiagnosis on delay in diagnosis and stage of PDAC is unknown. This study is a retrospective review (2000-2010) from a University-based cancer center of new diagnoses of proximal PDAC. Of 313 patients, 98 (31.3 %) had an initial misdiagnosis. Misdiagnosed patients were younger, 62.8 ± 12.6 vs. 68.0 ± 10.1 (p < 0.001). The most common initial misdiagnoses were: gallbladder disease, gastroesophageal reflux disease, and peptic ulcer disease. After excluding patients with prior cholecystectomy, 14.2 % were misdiagnosed with gallbladder disease and underwent cholecystectomy before PDAC diagnosis. Misdiagnosed patients had higher rates of abdominal pain (p < 0.001), weight loss (p = 0.04), and acute pancreatitis (p < 0.001) and lower rate of jaundice (p < 0.001). Median time between symptoms to PDAC diagnosis was longer in misdiagnosed: 4.2 months vs. 1.4 (p < 0.001). Median time from contact with medical provider to axial imaging was longer in misdiagnosed (p < 0.001). Rate of stages III-IV disease at diagnosis was higher in misdiagnosed: 61.2 vs. 43.7 % (p = 0.004), with a 1.4 (95 % confidence interval (CI), 1.12-1.74) higher risk of stages III-IV disease at diagnosis; however, there was no difference in median overall survival in misdiagnosed patients (9.6 months in misdiagnosed vs. 10.3 months in correctly diagnosed, p = 0.69). Initial misdiagnosis of patients with proximal PDAC is associated with delay in diagnosis and higher risk of locally advanced or advanced disease at time of PDAC diagnosis.

Palliative care is often initiated late for patients with end stage liver disease (ESLD) with pain being a common morbidity that is under-treated throughout the disease trajectory. When admitted to a palliative care unit (PCU), nurses play a pivotal role and must be highly informed to ensure effective pain management. The aim of this study is to determine the baseline level of knowledge and attitudes of PCU nurses regarding pain management in patients with ESLD. A descriptive, cross-sectional self-administered survey design was used for this study. The sample comprised 35 PCU nurses working at a continuing chronic care facility in Toronto, Ontario, Canada. Data on the knowledge and attitudes of the nurses regarding pain management in patients with ESLD, was obtained using a modified version of the "Nurses Knowledge and Attitudes Survey Regarding Pain" (NKASRP) tool. Thirty-one PCU nurses were included for the analysis, giving a response rate of 89%. The mean total percentage score for the nurses on the modified version of the NKASRP was 72%. Only 26% of the nurse participants obtained a passing score of 80% or greater. There were no significant differences in mean total scores by age, gender, years of nursing experience or education level. The findings of this study provide important information about the inadequate knowledge and attitude in nurses regarding pain management for patients with ESLD. It is suggested that targeted educational programs and quality improvement initiatives in pain management for patients with ESLD could improve knowledge and attitudes for PCU nurses.

Shear-Induced Amyloid Formation in the Brain: I. Potential Vascular and Parenchymal Processes.

PubMed

Trumbore, Conrad N

2016-09-06

Shear distortion of amyloid-beta (Aβ) solutions accelerates amyloid cascade reactions that may yield different toxic oligomers than those formed in quiescent solutions. Recent experiments indicate that cerebrospinal fluid (CSF) and interstitial fluid (ISF) containing Aβ flow through narrow brain perivascular pathways and brain parenchyma. This paper suggests that such flow causes shear distortion of Aβ molecules involving conformation changes that may be one of the initiating events in the etiology of Alzheimer's disease. Aβ shearing can occur in or around brain arteries and arterioles and is suggested as the origin of cerebral amyloid angiopathy deposits in cerebrovascular walls. Comparatively low flow rates of ISF within the narrow extracellular spaces (ECS) of the brain parenchyma are suggested as a possible initiating factor in both the formation of neurotoxic Aβ42 oligomers and amyloid fibrils. Aβ42 in slow-flowing ISF can gain significant shear energy at or near the walls of tortuous brain ECS flow paths, promoting the formation of a shear-distorted, excited state hydrophobic Aβ42* conformation. This Aβ42* molecule could possibly be involved in one of two paths, one involving rapid adsorption to a brain membrane surface, ultimately forming neurotoxic oligomers on membranes, and the other ultimately forming plaque within the ECS flow pathways. Rising Aβ concentrations combined with shear at or near critical brain membranes are proposed as contributing factors to Alzheimer's disease neurotoxicity. These hypotheses may be applicable in other neurodegenerative diseases, including tauopathies and alpha-synucleinopathies, in which shear-distorted proteins also may form in the brain ECS.

In 2008, the line item supporting sexually transmitted disease (STD) services in the Massachusetts state budget was cut as a result of budget shortfalls. Shortly thereafter, direct provision of STD clinical services supported by the Massachusetts Department of Public Health (MDPH) was suspended. Massachusetts Department of Public Health requested an initial assessment of its internal response and impact in 2010. A follow-up assessment occurred in September 2013. In 2010 and 2013, 39 and 46 staff, respectively, from MDPH and from clinical partner agencies, were interviewed about changes in the role of the MDPH, partnerships, STD services, challenges, and recommendations. Interview notes were summarized, analyzed, and synthesized by coauthors using qualitative analysis techniques and NVivo software. The withdrawal of state funding for STD services, and the subsequent reduction in clinical service hours, erected numerous barriers for Disease Intervention Specialists (DIS) seeking to ensure timely STD treatment for index cases and their partners. After initial instability, MDPH operations stabilized due partly to strong management, new staff, and intensified integration with human immunodeficiency virus services. Existing contracts with human immunodeficiency virus providers were leveraged to support alternative STD testing and care sites. Massachusetts Department of Public Health strengthened its clinical and epidemiologic expertise. The DIS expanded their scope of work and were outposted to select new sites. Challenges remained, however, such as a shortage of DIS staff to meet the needs. Although unique in many ways, MA offers experiences and lessons for how a state STD program can adapt to a changing public health context.

The COPD Assessment Test (CAT) is a valid disease-specific questionnaire measuring health status. However, knowledge concerning its use regarding patient and disease characteristics remains limited. Our main objective was to assess the degree to which the CAT score varies and can discriminate between specific patient population groups. The Canadian Cohort Obstructive Lung Disease (CanCOLD) is a random-sampled, population-based, multicenter, prospective cohort that includes subjects with COPD (Global Initiative for Chronic Obstructive Lung Disease [GOLD] classifications 1 to 3). The CAT questionnaire was administered at three visits (baseline, 1.5 years, and 3 years). The CAT total score was determined for sex, age groups, smoking status, GOLD classification, exacerbations, and comorbidities. A total of 716 subjects with COPD were included in the analysis. The majority of subjects (72.5%) were not previously diagnosed with COPD. The mean FEV 1 /FVC ratio was 61.1 ± 8.1%, with a mean FEV 1 % predicted of 82.3 ± 19.3%. The mean CAT scores were 5.8 ± 5.0, 9.6 ± 6.7, and 16.1 ± 10.0 for GOLD 1, 2, and 3+ classifications, respectively. Higher CAT scores were observed in women, current smokers, ever-smokers, and subjects with a previous diagnosis of COPD. The CAT was also able to distinguish between subjects who experience exacerbations vs those who had no exacerbation. These results suggest that the CAT, originally designed for use in clinically symptomatic patients with COPD, can also be used in individuals with mild airflow obstruction and newly diagnosed COPD. In addition, the CAT was able to discriminate between sexes and subjects who experience frequent and infrequent exacerbations. ClinicalTrials.gov; No.: NCT00920348; Study ID No.: IRO-93326.

Longitudinal Neuroimaging Hippocampal Markers for Diagnosing Alzheimer's Disease.

PubMed

Platero, Carlos; Lin, Lin; Tobar, M Carmen

2018-05-21

Hippocampal atrophy measures from magnetic resonance imaging (MRI) are powerful tools for monitoring Alzheimer's disease (AD) progression. In this paper, we introduce a longitudinal image analysis framework based on robust registration and simultaneous hippocampal segmentation and longitudinal marker classification of brain MRI of an arbitrary number of time points. The framework comprises two innovative parts: a longitudinal segmentation and a longitudinal classification step. The results show that both steps of the longitudinal pipeline improved the reliability and the accuracy of the discrimination between clinical groups. We introduce a novel approach to the joint segmentation of the hippocampus across multiple time points; this approach is based on graph cuts of longitudinal MRI scans with constraints on hippocampal atrophy and supported by atlases. Furthermore, we use linear mixed effect (LME) modeling for differential diagnosis between clinical groups. The classifiers are trained from the average residue between the longitudinal marker of the subjects and the LME model. In our experiments, we analyzed MRI-derived longitudinal hippocampal markers from two publicly available datasets (Alzheimer's Disease Neuroimaging Initiative, ADNI and Minimal Interval Resonance Imaging in Alzheimer's Disease, MIRIAD). In test/retest reliability experiments, the proposed method yielded lower volume errors and significantly higher dice overlaps than the cross-sectional approach (volume errors: 1.55% vs 0.8%; dice overlaps: 0.945 vs 0.975). To diagnose AD, the discrimination ability of our proposal gave an area under the receiver operating characteristic (ROC) curve (AUC) [Formula: see text] 0.947 for the control vs AD, AUC [Formula: see text] 0.720 for mild cognitive impairment (MCI) vs AD, and AUC [Formula: see text] 0.805 for the control vs MCI.

Emergence of Persistent Infection due to Heterogeneity

Agrawal, Vidit; Moitra, Promit; Sinha, Sudeshna

2017-02-01

We explore the emergence of persistent infection in a closed region where the disease progression of the individuals is given by the SIRS model, with an individual becoming infected on contact with another infected individual. We investigate the persistence of contagion qualitatively and quantitatively, under increasing heterogeneity in the partitioning of the population into different disease compartments, as well as increasing heterogeneity in the phases of the disease among individuals within a compartment. We observe that when the initial population is uniform, consisting of individuals at the same stage of disease progression, infection arising from a contagious seed does not persist. However when the initial population consists of randomly distributed refractory and susceptible individuals, a single source of infection can lead to sustained infection in the population, as heterogeneity facilitates the de-synchronization of the phases in the disease cycle of the individuals. We also show how the average size of the window of persistence of infection depends on the degree of heterogeneity in the initial composition of the population. In particular, we show that the infection eventually dies out when the entire initial population is susceptible, while even a few susceptibles among an heterogeneous refractory population gives rise to a large persistent infected set.

The increasing number of people with chronic diseases challenges workforce capacity. Type 2 diabetes (T2D) can have work-related consequences, such as early retirement. Laws of most high-income countries require workplaces to provide accommodations to enable people with chronic disabilities to manage their condition at work. A barrier to successful implementation of such accommodations can be lack of co-workers' willingness to support people with T2D. This study aimed to examine the willingness to pay (WTP) of people with and without T2D for five workplace initiatives that help individuals with type 2 diabetes manage their diabetes at work. Three samples with employed Danish participants were drawn from existing online panels: a general population sample (n = 600), a T2D sample (n = 693), and a matched sample of people without diabetes (n = 539). Participants completed discrete choice experiments eliciting their WTP (reduction in monthly salary, €/month) for five hypothetical workplace initiatives: part-time job, customized work, extra breaks with pay, and time off for medical consultations with and without pay. WTP was estimated by conditional logits models. Bootstrapping was used to estimate confidence intervals for WTP. There was an overall WTP for all initiatives. Average WTP for all attributes was 34 €/month (95% confidence interval [CI]: 27-43] in the general population sample, 32 €/month (95% CI: 26-38) in the T2D sample, and 55 €/month (95% CI: 43-71) in the matched sample. WTP for additional breaks with pay was considerably lower than for the other initiatives in all samples. People with T2D had significantly lower WTP than people without diabetes for part-time work, customized work, and time off without pay, but not for extra breaks or time off with pay. For people with and without T2D, WTP was present for initiatives that could improve management of diabetes at the workplace. WTP was lowest among people with T2D. Implementation of these initiatives seems feasible and may help unnecessary exclusion of people with T2D from work.

Can Lessons from Public Health Disease Surveillance Be Applied to Environmental Public Health Tracking?

PubMed Central

Ritz, Beate; Tager, Ira; Balmes, John

2005-01-01

Disease surveillance has a century-long tradition in public health, and environmental data have been collected at a national level by the U.S. Environmental Protection Agency for several decades. Recently, the Centers for Disease Control and Prevention announced an initiative to develop a national environmental public health tracking (EPHT) network with “linkage” of existing environmental and chronic disease data as a central goal. On the basis of experience with long-established disease surveillance systems, in this article we suggest how a system capable of linking routinely collected disease and exposure data should be developed, but caution that formal linkage of data is not the only approach required for an effective EPHT program. The primary operational goal of EPHT has to be the “treatment” of the environment to prevent and/or reduce exposures and minimize population risk for developing chronic diseases. Chronic, multifactorial diseases do not lend themselves to data-driven evaluations of intervention strategies, time trends, exposure patterns, or identification of at-risk populations based only on routinely collected surveillance data. Thus, EPHT should be synonymous with a dynamic process requiring regular system updates to a) incorporate new technologies to improve population-level exposure and disease assessment, b) allow public dissemination of new data that become available, c) allow the policy community to address new and emerging exposures and disease “threads,” and d) evaluate the effectiveness of EPHT over some appropriate time interval. It will be necessary to weigh the benefits of surveillance against its costs, but the major challenge will be to maintain support for this important new system. PMID:15743709

Although epidemiological research demonstrates that there is an association between lifestyle factors and risk of breast cancer recurrence, progression of disease, and mortality, no comprehensive lifestyle change clinical trials have been conducted to determine if changing multiple risk factors leads to changes in biobehavioral processes and clinical outcomes in women with breast cancer. This article describes the design, feasibility, adherence to the intervention and data collection, and patient experience of a comprehensive lifestyle change clinical trial (CompLife). CompLife is a randomized, controlled trial of a multiple-behavior intervention focusing on diet, exercise, and mind-body practice along with behavioral counseling to support change. The initial exposure to the intervention takes place during the 4 to 6 weeks of radiotherapy (XRT) for women with stage III breast cancer and then across the subsequent 12 months. The intervention group will have 42 hours of in-person lifestyle counseling during XRT (7-10 hours a week) followed by up to 30 hours of counseling via video connection for the subsequent 12 months (weekly sessions for 6 months and then monthly for 6 months). The primary outcome is disease-free survival. Multiple secondary outcomes are being evaluated, including: (1) biological pathways; (2) overall survival; (3) patient-reported outcomes; (4) dietary patterns/fitness levels, anthropometrics, and body composition; and (5) economic outcomes. Qualitative data of the patient experience in the trial is collected from exit interviews, concluding remarks, direct email correspondences, and web postings from patients. Fifty-five patients have been recruited and randomized to the trial to date. Accrual of eligible patients is high (72%) and dropout rates extremely low (5%). Attendance to the in-person sessions is high (95% attending greater than 80% of sessions) as well as to the 30 hours of video counseling (88% attending more than 70% of sessions). Adherence to components of the behavior change intervention is high and compliance with the intensive amount of data collection is exceptional. Qualitative data collected from the participants reveals testimonials supporting the importance of the comprehensive nature of intervention, especially the mind-body/mindfulness component and social support, and meaningful lifestyle transformations. Conducting a comprehensive, multicomponent, lifestyle change clinical trial for women with breast was feasible and collection of biobehavioral outcomes successful. Adherence to behavior change was high and patient experience was overwhelmingly positive.

Outcomes After Whole Brain Reirradiation in Patients With Brain Metastases

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

Son, Christina H.; Jimenez, Rachel; Niemierko, Andrzej

Purpose: Patients with brain metastases are often treated with whole brain radiation therapy (WBRT) for purposes of palliation. The treatment of those who experience subsequent intracranial disease progression can include a second course of WBRT, although there is controversy surrounding its safety and efficacy. This study examines the outcomes in patients at Massachusetts General Hospital who underwent reirradiation. Patients and Methods: We examined the medical records of 17 patients at Massachusetts General Hospital with brain metastases who were initially treated with WBRT between 2002 and 2008 and were subsequently retreated with a second course of WBRT. The median dose formore » the first course of WBRT was 35 Gy (range, 28-40 Gy), with a fraction size of 2 to 3 Gy (median, 2.5 Gy). The median dose at reirradiation was 21.6 Gy (range, 14-30 Gy), with a fraction size of 1.5 to 2 Gy (median, 1.8 Gy). Results: The second course of WBRT was administered upon radiographic disease progression in all patients. Of 10 patients with complete follow-up data, 8 patients experienced complete or partial symptom resolution, and 2 did not show clinical improvement. The time to radiographic progression was 5.2 months. The median overall survival for all patients after diagnosis of metastases was 24.7 months. The median survival time after initiation of reirradiation was 5.2 months (95% CI, 1.3-8.7). In 6 patients with stable extracranial disease, the median survival time after retreatment was 19.8 months (95% CI, 2.7-{infinity}), compared with 2.5 months (95% CI, 0.8-5.5) for those with extracranial disease progression (p = 0.05). Acute adverse reactions occurred in 70.5% of patients but were mild to moderate in severity. Conclusion: In select patients and especially those with stable extracranial disease, reirradiation may be an appropriate and effective intervention to provide symptomatic relief and slow intracranial disease progression. Side effects were minimal and did not cause substantial changes in quality of life.« less

Ghana is a Buruli ulcer (BU) endemic country yet there is paucity of socio-cultural research on BU. Examining distinctive experiences and meanings for pre-ulcers and ulcers of BU may clarify the disease burden, illness experience and local perceptions of causes and spread, and environmental features of BU, which are useful to guide public health programmes and future research. This study aimed to explain local meanings and experiences of BU for persons with pre-ulcers and ulcers in the Ga-West and Ga-South municipalities in Accra. Semi-structured interviews based on the Explanatory Model Interview Catalogue framework were administered to 181 respondents comprising 15 respondents with pre-ulcers and 166 respondents with ulcers. The Wilcoxon rank-sum test was used to compare categories of illness experiences (PD) and perceived causes (PC) among respondents with pre-ulcer and ulcer conditions. The Fisher's exact test was used to compare the most troubling PD and the most important PC variables. Qualitative phenomenological analysis of respondents' narratives clarified illness experiences and meanings with reference to PC and PD variables. Families of respondents with pre-ulcers and the respondents themselves were often anxious about disease progression, while families of respondents with ulcers, who had to give care, worried about income loss and disruption of school attendance. Respondents with pre-ulcers frequently reported swimming in ponds and rivers as a perceived cause and considered it as the most important PC (53.3%). Respondents with ulcers frequently attributed their BU illness to witchcraft (64.5%) and respondents who claimed they had no water contact, questioned the credibility of health messages Affected persons with pre-ulcers are likely to delay treatment because of social and financial constraints and the absence of pain. Scepticism on the role of water in disease contagion and prolonged healing is perceived to make ideas of witchcraft as a PC more credible, among respondents with ulcers. Health messages should address issues of locally perceived risk and vulnerability. Guided by study findings, further research on the role of environmental, socio-cultural and genetic factors in BU contagion, is also needed to clarify and formulate health messages and strengthen public health initiatives.

Methods Semi-structured interviews based on the Explanatory Model Interview Catalogue framework were administered to 181 respondents comprising 15 respondents with pre-ulcers and 166 respondents with ulcers. The Wilcoxon rank-sum test was used to compare categories of illness experiences (PD) and perceived causes (PC) among respondents with pre-ulcer and ulcer conditions. The Fisher’s exact test was used to compare the most troubling PD and the most important PC variables. Qualitative phenomenological analysis of respondents’ narratives clarified illness experiences and meanings with reference to PC and PD variables. Results Families of respondents with pre-ulcers and the respondents themselves were often anxious about disease progression, while families of respondents with ulcers, who had to give care, worried about income loss and disruption of school attendance. Respondents with pre-ulcers frequently reported swimming in ponds and rivers as a perceived cause and considered it as the most important PC (53.3%). Respondents with ulcers frequently attributed their BU illness to witchcraft (64.5%) and respondents who claimed they had no water contact, questioned the credibility of health messages Conclusions Affected persons with pre-ulcers are likely to delay treatment because of social and financial constraints and the absence of pain. Scepticism on the role of water in disease contagion and prolonged healing is perceived to make ideas of witchcraft as a PC more credible, among respondents with ulcers. Health messages should address issues of locally perceived risk and vulnerability. Guided by study findings, further research on the role of environmental, socio-cultural and genetic factors in BU contagion, is also needed to clarify and formulate health messages and strengthen public health initiatives.

Implementation of new models of development cooperation have been on the increase lately. Coupled with this are calls for use of horizontal development cooperation mechanisms such as South-South Cooperation (SSC) as a way to enhance aid effectiveness in the health sector of developing countries. In this case series, we review recent experiences in the application of SSC initiatives to two public health situations in Africa to demonstrate the veracity of this new paradigm. Our review highlight the immense benefits associated with the use of SSC for health and provide evidence for increasing use of horizontal development coordination mechanisms to strengthen public health services delivery and socioeconomic development among African countries. Opportunities for SSC among African countries include in the areas of disease prevention and control, production of medical products and essential medicines, harmonization of regulatory processes, and health workforce development among others. However, pitfalls such as poor coordination, inadequate political commitment, lack of conducive policy environments, language barrier and inadequate financing opportunities for SSC initiatives present major dilemma for the use of SSC mechanisms. We conclude that the need for a paradigm shift from vertical to horizontal development cooperation needs no further proof but a call to action. We call on the concerned stakeholders to support the establishment of a systematic approach for use of SSC mechanisms in the health sector of Africa, designation of an African Centre of Excellence for SSC in public health and development of a regional mechanism for monitoring and evaluation of SSC initiatives in Africa.

Fingolimod was the first oral and the first in class disease modifying treatment in multiple sclerosis that acts as sphingosine-1-phospathe receptor agonist. Since approval in 2010 there is a growing experience with fingolimod use in clinical practice, but also next-generation sphingosin-1-receptor agonists in ongoing clinical trials. Growing evidence demonstrates additional effects beyond impact on lymphocyte circulation, highlighting further promising targets in multiple sclerosis therapy. Areas covered: Here we present a systematic review using PubMed database searching and expert opinion on fingolimod use in clinical practice. Long-term data of initial clinical trials and post-marketing evaluations including long-term efficacy, safety, tolerability and management especially within growing disease modifying treatment options and pre-treatment constellation in multiple sclerosis patients are critically discussed. Furthermore novel findings in mechanism of actions and prospective on additional use in progressive forms in multiple sclerosis are presented. Expert opinion: There is an extensive long-term experience on fingolimod use in clinical practice demonstrating the favorable benefit-risk of this drug. Using a defined risk management approach experienced MS clinicians should apply fingolimod after critical choice of patients and review of clinical aspects. Further studies are essential to discuss additional benefit in progressive forms in multiple sclerosis.

Modifying mixing and instability growth through the adjustment of initial conditions in a high-energy-density counter-propagating shear experiment on OMEGA

2015-06-24

Counter-propagating shear experiments conducted at the OMEGA Laser Facility have been evaluating the effect of target initial conditions, specifically the characteristics of a tracer foil located at the shear boundary, on Kelvin-Helmholtz instability evolution and experiment transition toward nonlinearity and turbulence in the high-energy-density (HED) regime. Experiments are focused on both identifying and uncoupling the dependence of the model initial turbulent length scale in variable-density turbulence models of k-ϵ type on competing physical instability seed lengths as well as developing a path toward fully developed turbulent HED experiments. We present results from a series of experiments controllably and independently varyingmore » two initial types of scale lengths in the experiment: the thickness and surface roughness (surface perturbation scale spectrum) of a tracer layer at the shear interface. We show that decreasing the layer thickness and increasing the surface roughness both have the ability to increase the relative mixing in the system, and thus theoretically decrease the time required to begin transitioning to turbulence in the system. In addition, we also show that we can connect a change in observed mix width growth due to increased foil surface roughness to an analytically predicted change in model initial turbulent scale lengths.« less

Robot-Assisted Mckeown Esophagectomy is Feasible After Neoadjuvant Chemoradiation. Our Initial Experience.

Neoadjuvant chemoradiation has become the standard of care for esophageal cancer, especially for middle third esophageal lesions and those with squamous histology. Although more and more thoracic surgeons and surgical oncologists have now shifted to video-assisted and robot-assisted thoracoscopic esophagectomy; there is still limited experience for the use of minimal-assisted approaches in patients undergoing surgery after neoadjuvant chemoradiation. Most surgeons have concerns of feasibility, safety, and oncological outcomes as well as issues related to difficult learning curve in adopting robotic esophagectomy in patients after chemoradiation. We present our initial experience of Robot-Assisted Mckeown Esophagectomy in 27 patients after neoadjuvant chemoradiation, from May 2013 to October 2014. All patients underwent neoadjuvant chemoradiation to a dose of 50.4 Gy/25Fr with concurrent weekly cisplatin, followed by reassessment with clinical examination and repeat FDG PET/CT 6 weeks after completion of chemoradiation. Patients with progressive disease underwent palliative chemotherapy while patients with either partial or significant response to chemoradiation underwent Robot-Assisted Mckeown Esophagectomy with esophageal replacement by gastric conduit and esophagogastric anastomosis in the left neck. Out of 27 patients, 92.5 % patients had stage cT3/T4 tumours and node-positive disease in 48.1 % on imaging. Most patients were middle thoracic esophageal cancers (23/27), with squamous histology in all except for one. All patients received neoadjuvant chemoradiation and subsequently underwent Robot Assisted Mckeown Esophagectomy. The average time for robot docking, thoracic mobilization and total surgical procedure was 13.2, 108.4 and 342.7 min, respectively. The procedure was well tolerated by all patients with only one case of peri-operative mortality. Average ICU stay was 6.35 days (range 3-9 days). R0 resection rate of 96.3 % and average lymph node yield of 18 could be achieved. Pathological node negativity rate (pN0) and complete response (pCR) were 66.6 and 44.4 %, respectively. In the initial cases, four patients had to be converted to open due technical reasons or intraoperative complications. The present study, with shorter operative times, similar ICU stay, overall low morbidity, and mortality and optimal oncological outcomes suggest that robot-assisted thoracic mobilization of esophagus in patients with prior chemoradiation is feasible and safe with acceptable oncological outcomes. It has a shorter learning curve and hence allows for a transthoracic minimally invasive transthoracic esophagectomy to more and more patients, otherwise unfit for conventional approach.

The Tokyo Medical University Hospital in Japan and the Lund University hospital in Sweden have recently initiated a research program with the objective to impact on patient treatment by clinical disease stage characterization (phenotyping), utilizing proteomics sequencing platforms. By sharing clinical experiences, patient treatment principles, and biobank strategies, our respective clinical teams in Japan and Sweden will aid in the development of predictive and drug related protein biomarkers. Data from joint lung cancer studies are presented where protein expression from Neuro- Endocrine lung cancer (LCNEC) phenotype patients can be separated from Small cell- (SCLC) and Large Cell lung cancer (LCC) patients by deep sequencing and spectral counting analysis. LCNEC, a subtype of large cell carcinoma (LCC), is characterized by neuroendocrine differentiation that small cell lung carcinoma (SCLC) shares. Pre-therapeutic histological distinction between LCNEC and SCLC has so far been problematic, leading to adverse clinical outcome. An establishment of protein targets characteristic of LCNEC is quite helpful for decision of optimal therapeutic strategy by diagnosing individual patients. Proteoform annotation and clinical biobanking is part of the HUPO initiative (http://www.hupo.org) within chromosome 10 and chromosome 19 consortia.

Labour room Continuous Positive Airway Pressure (LR CPAP) in preterm neonates <34 weeks: An Indian experience.

2017-01-01

Early continuous positive airway pressure (CPAP) has proven to be beneficial in reducing ventilator dependence and subsequent chronic lung disease in neonates suffering from Respiratory distress syndrome (RDS). However, the efficacy of initiating labour room (LR) CPAP has not been determined prospectively in resource limited settings like India. Hence the objective of the present study was to study the efficacy of LR CPAP in preterm neonates with RDS in resource limited Indian settings. This was a prospective observational study including preterm neonates (26-34 weeks with RDS) carried out over a period of 6 months (January to June 2016) when the CPAP was initiated in LR. The outcome was compared with a similar population during the corresponding period of the previous year when CPAP was initiated in NICU. The historical controls were retrieved from case records and matched for gestational age and birth weight with the study population. There was 36% absolute risk reduction in the need for surfactant and 56% for mechanical ventilation in the LR CPAP group respectively. LR CPAP reduces the need for mechanical ventilation and surfactant in preterm neonates with RDS in resource limited settings.

Performance Enhancement of Pharmacokinetic Diffuse Fluorescence Tomography by Use of Adaptive Extended Kalman Filtering.

2015-01-01

Due to both the physiological and morphological differences in the vascularization between healthy and diseased tissues, pharmacokinetic diffuse fluorescence tomography (DFT) can provide contrast-enhanced and comprehensive information for tumor diagnosis and staging. In this regime, the extended Kalman filtering (EKF) based method shows numerous advantages including accurate modeling, online estimation of multiparameters, and universal applicability to any optical fluorophore. Nevertheless the performance of the conventional EKF highly hinges on the exact and inaccessible prior knowledge about the initial values. To address the above issues, an adaptive-EKF scheme is proposed based on a two-compartmental model for the enhancement, which utilizes a variable forgetting-factor to compensate the inaccuracy of the initial states and emphasize the effect of the current data. It is demonstrated using two-dimensional simulative investigations on a circular domain that the proposed adaptive-EKF can obtain preferable estimation of the pharmacokinetic-rates to the conventional-EKF and the enhanced-EKF in terms of quantitativeness, noise robustness, and initialization independence. Further three-dimensional numerical experiments on a digital mouse model validate the efficacy of the method as applied in realistic biological systems.

The role of the Alzheimer’s Disease Neuroimaging Initiative Genetics Core is to facilitate the investigation of genetic influences on disease onset and trajectory as reflected in structural, functional, and molecular imaging changes; fluid biomarkers; and cognitive status. Major goals include (1) blood sample processing, genotyping, and dissemination, (2) genome-wide association studies (GWAS) of longitudinal phenotypic data, and (3) providing a central resource, point of contact and planning group for genetics within Alzheimer’s Disease Neuroimaging Initiative. Genome-wide array data have been publicly released and updated, and several neuroimaging GWAS have recently been reported examining baseline magnetic resonance imaging measures as quantitative phenotypes. Other preliminary investigations include copy number variation in mild cognitive impairment and Alzheimer’s disease and GWAS of baseline cerebrospinal fluid biomarkers and longitudinal changes on magnetic resonance imaging. Blood collection for RNA studies is a new direction. Genetic studies of longitudinal phenotypes hold promise for elucidating disease mechanisms and risk, development of therapeutic strategies, and refining selection criteria for clinical trials.

Ensuring safe and quality care for patients in hospitals is an important part of a nurse manager's role. Continuous quality improvement has been identified as one approach that leads to the delivery of quality care services to patients and is widely used by nurse managers to improve patient care. Nurse managers' experiences in initiating continuous quality improvement activities in resource-poor healthcare settings remain largely unknown. Research evidence is highly demanded in these settings to address disease burden and evidence-based practice. This interpretive qualitative study was conducted to gain an understanding of nurse managers' Continuous Quality Improvement experiences in rural hospitals in Uganda. Nurse managers in rural healthcare settings used their role to prioritize quality improvement activities, monitor the Continuous Quality Improvement process, and utilize in-service education to support continuous quality improvement. The nurse managers in our sample encountered a number of barriers during the implementation of Continuous Quality Improvement, including: limited patient participation, lack of materials, and limited human resources. Efforts to address the challenges faced through good governance and leadership development require more attention. © 2017 John Wiley & Sons Australia, Ltd.

State of psychiatry in Italy 35 years after psychiatric reform. A critical appraisal of national and local data.

2012-08-01

Thirty-four years have elapsed since the passing of the Italian Law 180, the reform law that marked the transition from a hospital-based system of care to a model of community psychiatry that was designed to be an alternative to, rather than to complement, the old hospital-centred services. The main principle of Law 180 is that psychiatric patients have the right to be treated the same way as patients with other diseases and only voluntary treatments are allowed, with a few exceptions that are strictly regulated. The main features and consequences of the Italian reform are initially reviewed; national and local level experiences and epidemiological data are then analysed in order to highlight and disentangle the 'active ingredients' of the Italian experience. A public health attitude with the capacity to network good practice in service organization by giving voice to successful experiences and promoting health service research, apart from some local services, is still generally lacking. Furthermore, it is still difficult to provide an evidence-based reply to the question: can à l'Italienne community-care be exported elsewhere?

[Two hundred blood tests from Auschwitz. A notorious research project and the question about the contribution Adolf Butenandts].

PubMed

Trunk, Achim

2007-01-01

The 1939 Nobel Laureate in Chemistry and later President of the Max Planck Society Adolf Butenandt has been increasingly exposed to criticism in recent years. One far-reaching accusation against him is his postulated participation in the human experiments executed by the SS-physician Josef Mengele in the Auschwitz concentration camp. It concerns a project initiated by anthropologist Otmar von Verschuer in 1943. For this, Verschu-ER Obtained blood samples from his assistant Mengele in the Auschwitz concentration camp. When methodological problems occurred in the project Butenandt helped Verschuer. According to the reconstruction of geneticist Benno Müller-Hill the research project included lethal human experiments: Mengele had selectively infected concentration camp detainees with tuberculosis to observe their racially conditioned resistibility against that disease, he claims. This reconstruction, however, contradicts other sources. Therefore an alternative reconstruction is offered here. According to that, the project represented a large-scale attempt of serological race diagnosis in man. Human experiments are not plausible for this project. Yet it is clearly connected to race biological research and implementation.

Risk of thromboembolic complications in adult congenital heart disease: A literature review.

Karsenty, Clement; Zhao, Alexandre; Marijon, Eloi; Ladouceur, Magalie

2018-05-30

Adult congenital heart disease (ACHD) is a constantly expanding population with challenging issues. Initial medical and surgical treatments are seldom curative, and the majority of patients still experience late sequelae and complications, especially thromboembolic events. These common and potentially life-threating adverse events are probably dramatically underdiagnosed. Better identification and understanding of thromboembolic risk factors are essential to prevent long-term related morbidities. In addition to specific situations associated with a high risk of thromboembolic events (Fontan circulation, cyanotic congenital heart disease), atrial arrhythmia has been recognized as an important risk factor for thromboembolic events in ACHD. Unlike in patients without ACHD, thromboembolic risk stratification scores, such as the CHA 2 DS 2 -VASc score, may not be applicable in ACHD. Overall, after a review of the scientific data published so far, it is clear that the complexity of the underlying congenital heart disease represents a major risk factor for thromboembolic events. As a consequence, prophylactic anticoagulation is indicated in patients with complex congenital heart disease and atrial arrhythmia, regardless of the other risk factors, as opposed to simple heart defects. The landscape of ACHD is an ongoing evolving process, and specific thromboembolic risk scores are needed, especially in the setting of simple heart defects; these should be coupled with specific trials or long-term follow-up of multicentre cohorts.

Analysis of phase II methodologies for single-arm clinical trials with multiple endpoints in rare cancers: An example in Ewing’s sarcoma

PubMed Central

Dutton, P; Love, SB; Billingham, L; Hassan, AB

2016-01-01

Trials run in either rare diseases, such as rare cancers, or rare sub-populations of common diseases are challenging in terms of identifying, recruiting and treating sufficient patients in a sensible period. Treatments for rare diseases are often designed for other disease areas and then later proposed as possible treatments for the rare disease after initial phase I testing is complete. To ensure the trial is in the best interests of the patient participants, frequent interim analyses are needed to force the trial to stop promptly if the treatment is futile or toxic. These non-definitive phase II trials should also be stopped for efficacy to accelerate research progress if the treatment proves to be particularly promising. In this paper, we review frequentist and Bayesian methods that have been adapted to incorporate two binary endpoints and frequent interim analyses. The Eurosarc Trial of Linsitinib in advanced Ewing Sarcoma (LINES) is used as a motivating example and provides a suitable platform to compare these approaches. The Bayesian approach provides greater design flexibility, but does not provide additional value over the frequentist approaches in a single trial setting when the prior is non-informative. However, Bayesian designs are able to borrow from any previous experience, using prior information to improve efficiency. PMID:27587590

Evaluation of osteoarthritis progression using polarization-sensitive optical coherence tomography

2004-07-01

Osteoarthritis is a prevalent medical condition that presents a diagnostic and therapeutic challenge to physicians today because of the inability to assess the integrity of the articular cartilage early in the disease. Polarization sensitive optical coherence tomography (PS-OCT) is a high resolution, non-contact imaging modality that provides cross-sectional images with additional information regarding the integrity of the collagen matrix. Using PS-OCT to image provides information regarding thickness of the articular cartilage and gives an index of biochemical changes based on alterations in optical properties (i.e. birefringence) of the tissue. We demonstrate initial experiments performed on specimens collected following total knee replacement surgery. Articular cartilage was imaged using a 1310 nm PS-OCT system where both intensity and phase images were acquired. PS-OCT images were compared with histology, and the changes in tissue optical properties were characterized. Analysis of the intensity images demonstrates differences between healthy and diseased cartilage surface and thickness. Phase maps of the tissue demonstrated distinct differences between healthy and diseased tissue. PS-OCT was able to image a gradual loss of birefringence as the tissue became more diseased. In this way, determining the rate of change of the phase provides a quantitative measure of pathology. Thus, imaging and evaluation of osteoarthritis using PS-OCT can be a useful means of quantitative assessment of the disease.

The concept ``psychosomatic'', initially introduced in the first half of this century, has recently being reconfirmed by the theory and practice of modern medicine. The psychosomatic disorders are generally defined as physical (somatic) diseases produced, in part, by psychological factors, primarily stress. The organs of cardiovascular, gastrointestinal, respiratory and endocrine system are being affected, as a result of innervation by the autonomic nervous system. In some of these diseases the psychological factors can play relatively essential role; these are named ``primary psychosomatic diseases'': essential hypertension, peptic ulcer, bronchial asthma, ulcerative colitis, neurodermatitis, rheumatoid arthritis and hyperthyroidism (the last two diseasesmore » were later replaced by eating disorders as bulimia and anorexia nervosa). In many other cases the psychological element is only one among several parallel factors; these are sometimes called ``secondary psychosomatic diseases''. As known from the psychosomatic medicine, the stressors are being refracted through the individual history of a person as through a prism, leading to a spectrum of possible reactions. The personality prism comprises heredity, early child experiences and actual conflict, while the resulting disorders, as a response of the human being, have the form of neuroses, disturbed behavior and psychoses from one side, and psychophysiological disorders and other psychosomatic diseases, including synergetic amplification, from the other side. The probability of each outcome depends primarily on the individual personality prism, as well as on the characteristics of the stressors.« less

2000-09-01

To evaluate prospectively the efficacy of extracorporeal shock wave therapy (ESWT) as a conservative treatment for Peyronie's disease. After obtaining ethical committee approval, 37 patients with Peyronie's disease were treated using ESWT. Before treatment the degree of angulation was assessed by artificially inducing an erection with a vacuum device. The severity of pain on erection was assessed using a visual analogue scale (0-5). Each patient was treated with a minimum of three sessions of ESWT (3000 shock waves at an energy density of 0.11-0.17 mJ/mm2) at 3-week intervals. The results were analysed using the Wilcoxon signed-rank test. Of the 37 patients, 34 completed the protocol; the mean (range) duration of the disease was 19.43 (4-60) months and the mean follow-up 7.5 (5-11) months. Almost half (47%) of the patients reported an improvement in angulation, with a mean reduction of 29.3 degrees (10 degrees -60 degrees ) (P < 0.001); 12 of the 20 (60%) patients with pain on erection reported immediate relief, the mean reduction being 2.3 (1-4) on the visual analogue scale (P < 0.001). There was only minimal bruising at the site of treatment and no major side-effects were reported. ESWT is an effective and safe treatment for Peyronie's disease; the long-term follow-up and results are awaited.

Epilepsy is a very common disease in Spain. There is a great lack of information on real epidemiological data and the patient impact of this disease. The objective of the Spanish Foundation for Neurological Diseases (FEEN) report is to collect epidemiological data, morbidity, mortality and costs of this disease in Spain. A search was carried out in Medline on publications up to 2010, as well as a review of data published by the Spanish National Statistics Institute (INE). There are about 400,000 patients with epilepsy in Spain. Approximately 5 -10% of the population will experience a seizure in their lifetime, and up to 20% of these will have recurrent seizures. Using hospital discharge report data, hospital admissions for epilepsy are around 35 patients per 100,000 patients. Mortality risk in epileptic patients is two or three times higher than in non-epileptics. The mean total annual cost of drug resistant epilepsy patient in Spain is 6,935 Euros. The total cost of epilepsy according to data from the year 2000 could be around 5% of the total health budget. It is very important to maintain disease registers. This initiative should be encouraged by the patient associations and scientific societies. This report confirms that epilepsy has a great social and health impact on the population.

Few studies have examined inflammatory bowel disease (IBD) patients' knowledge and understanding of biologic therapies outside traditional surveys. Here, we used social media data to examine IBD patients' understanding of the risks and benefits associated with biologic therapies and how this affects decision-making. We collected posts from Twitter and e-forum discussions from >3000 social media sites posted between June 27, 2012 and June 27, 2015. Guided by natural language processing, we identified posts with specific IBD keywords that discussed the risks and/or benefits of biologics. We then manually coded the resulting posts and performed qualitative analysis using ATLAS.ti software. A hierarchical coding structure was developed based on the keyword list and relevant themes were identified through manual coding. We examined 1598 IBD-related posts, of which 452 (28.3%) centered on the risks and/or benefits of biologics. There were 5 main themes: negative experiences and concerns with biologics (n = 247; 54.6%), decision-making surrounding biologic use (n = 169; 37.4%), positive experiences with biologics (n = 168; 37.2%), information seeking from peers (n = 125; 27.7%), and cost (n = 38; 8.4%). Posts describing negative experiences primarily commented on side effects from biologics, concerns about potential side effects and increased cancer risk, and pregnancy safety concerns. Posts on decision-making focused on nonbiologic treatment options, hesitation to initiate biologics, and concerns about changing or discontinuing regimens. Social media reveals a wide range of themes governing patients' experience and choice with IBD biologics. The complexity of navigating their risk-benefit profiles suggests merit in creating online tailored decision tools to support IBD patients' decision-making with biologic therapies.

Text and data mining play an important role in obtaining insights from Health and Hospital Information Systems. This paper presents a text mining system for detecting admissions marked as positive for several diseases: Lung Cancer, Breast Cancer, Colon Cancer, Secondary Malignant Neoplasm of Respiratory and Digestive Organs, Multiple Myeloma and Malignant Plasma Cell Neoplasms, Pneumonia, and Pulmonary Embolism. We specifically examine the effect of linking multiple data sources on text classification performance. Support Vector Machine classifiers are built for eight data source combinations, and evaluated using the metrics of Precision, Recall and F-Score. Sub-sampling techniques are used to address unbalanced datasets of medical records. We use radiology reports as an initial data source and add other sources, such as pathology reports and patient and hospital admission data, in order to assess the research question regarding the impact of the value of multiple data sources. Statistical significance is measured using the Wilcoxon signed-rank test. A second set of experiments explores aspects of the system in greater depth, focusing on Lung Cancer. We explore the impact of feature selection; analyse the learning curve; examine the effect of restricting admissions to only those containing reports from all data sources; and examine the impact of reducing the sub-sampling. These experiments provide better understanding of how to best apply text classification in the context of imbalanced data of variable completeness. Radiology questions plus patient and hospital admission data contribute valuable information for detecting most of the diseases, significantly improving performance when added to radiology reports alone or to the combination of radiology and pathology reports. Overall, linking data sources significantly improved classification performance for all the diseases examined. However, there is no single approach that suits all scenarios; the choice of the most effective combination of data sources depends on the specific disease to be classified.

This chapter discusses the challenges faced in the development and implementation of musculoskeletal (MSK) Models of Care (MoCs) in middle-income and low-income countries in Asia and outlines the components of an effective MoC for MSK conditions. Case studies of four such countries (The Philippines, Malaysia, Bangladesh and Myanmar) are presented, and their unique implementation issues are discussed. The success experienced in one high-income country (Singapore) is also described as a comparison. The Community Oriented Program for Control of Rheumatic Diseases (COPCORD) project and the role of Asia Pacific League of Associations for Rheumatology (APLAR), a professional body supporting MoC initiatives in this region, are also discussed. The experience and lessons learned from these case studies can provide useful information to guide the implementation of future MSK MoC initiatives in other middle-income and low-income countries.

The Global Commission for the Certification of the Eradication of Poliomyelitis certified the eradication of type 2 poliovirus in September 2015, making type 2 poliovirus the first human pathogen to be eradicated since smallpox. The eradication of type 2 poliovirus, the absence of detection of type 3 poliovirus worldwide since November 2012, and cornering type 1 poliovirus to only a few geographic areas of 3 countries has enabled implementation of the endgame of polio eradication which calls for a phased withdrawal of oral polio vaccine beginning with the type 2 component, introduction of inactivated poliovirus vaccine, strengthening of routine immunization in countries with extensive polio resources, and initiating activities to transition polio resources, program experience, and lessons learned to other global health initiatives. This supplement focuses on efforts by global partners to successfully launch polio endgame activities to permanently secure and sustain the enormous gains of polio eradication forever. © The Author 2017.

Measles and rubella elimination: learning from polio eradication and moving forward with a diagonal approach.

Goodson, James L; Alexander, James P; Linkins, Robert W; Orenstein, Walter A

2017-12-01

In 1988, an estimated 350,000 children were paralyzed by polio and 125 countries reported polio cases, the World Health Assembly passed a resolution to achieve polio eradication by 2000, and the Global Polio Eradication Initiative (GPEI) was established as a partnership focused on eradication. Today, following eradication efforts, polio cases have decreased >99% and eradication of all three types of wild polioviruses is approaching. However, since polio resources substantially support disease surveillance and other health programs, losing polio assets could reverse progress toward achieving Global Vaccine Action Plan goals. Areas covered: As the end of polio approaches and GPEI funds and capacity decrease, we document knowledge, experience, and lessons learned from 30 years of polio eradication. Expert commentary: Transitioning polio assets to measles and rubella (MR) elimination efforts would accelerate progress toward global vaccination coverage and equity. MR elimination feasibility and benefits have long been established. Focusing efforts on MR elimination after achieving polio eradication would make a permanent impact on reducing child mortality but should be done through a 'diagonal approach' of using measles disease transmission to identify areas possibly susceptible to other vaccine-preventable diseases and to strengthen the overall immunization and health systems to achieve disease-specific goals.

Although routine screening reduces cervical cancer rates between 60-90%, thousands of women worldwide are diagnosed with the disease on an annual basis due to inadequate screening. Haitian women in South Florida experience a disproportionate burden of cervical cancer with disease rates four times higher than the average for women in Miami. An ongoing community based-participatory research (CBPR) initiative to assess and reduce this burden reveals that a complex interplay of factors contributes to lack of access to screening in this community including socioeconomics, language barriers, and traditional understandings of health and disease. In an effort to address some of these barriers and encourage uptake of primary and secondary cervical cancer prevention strategies, two videos on cervical cancer prevention were created using a CBPR framework. The video screenplays were created by a Haitian screenwriter using evidence-based medical information provided by academic researchers. The films feature Haitian actors speaking a Haitian Kreyòl dialogue with a storyline portraying friends and family discussing human papillomavirus (HPV) disease and vaccination, Papanicolaou (Pap) testing, and cervical cancer. Focus groups held with Haitian women in South Florida suggest the films are engaging, feature relatable characters, and impact knowledge about HPV, cervical cancer development, and current prevention recommendations.

A study of mothers' attitudes towards the prevention of caries with particular reference to fluoridation and vaccination.

PubMed

Kay, E J; Blinkhorn, A S

1989-12-01

Three hundred and fifteen mothers of pre-school children from socially deprived areas in Scotland were interviewed to assess their knowledge of, and attitudes towards, caries prevention. Thirty-five per cent of them believed that the dental profession had the most important part to play in the prevention of dental disease, while thirty-five per cent were complacent about their children's teeth and did not feel that preventive measures were necessary. Sixty-seven per cent thought that a caries vaccine would be acceptable if it posed no health risks and reduced caries experience by 50 per cent. This proportion increased to 78 per cent if all caries could be avoided by being immunized. Significantly more mothers held positive attitudes towards a hypothetical vaccine than to the more realistic prospect of fluoridation of public water supplies. This study has shown that mothers in deprived areas have little understanding of how to control dental disease and see little point in taking a personal initiative to alter their children's behaviour to reduce the risk of caries. They prefer to leave the control of disease to the dental profession. The idea that dental disease might be reduced by a vaccine was more acceptable than fluoridation.

The marketing of testosterone treatments for age-related low testosterone or 'Low T'.

PubMed

Mintzes, Barbara

2018-06-01

To summarize the research evidence on promotion of testosterone for 'Low T', or age-related hypogonadism. Marketing of testosterone for 'Low T' has relied on strategies that are inadequately regulated to prevent off-label promotion, such as unbranded 'disease-awareness' advertising campaigns targeting the general public, sponsored continuing medical education (CME) and ghostwriting. A recent US analysis of television advertising exposure levels versus insurance claims found that both unbranded 'disease-awareness' advertising and branded ads were associated with increased rates of testosterone testing, treatment initiation, and treatment without prior testing. Exposés of sponsored CME and ghostwriting indicate misrepresentation of the research evidence on the sequelae of untreated low testosterone and on treatment efficacy. In the United States, advertising to the general public ceased in 2014 after the Food and Drug Administration changed product labeling to clarify that testosterone is only indicated for pathological hypogonadism. Unbranded 'disease-awareness' advertising to the general public and 'Low T' messages for health professionals have continued elsewhere. The review of the experience of promotion of testosterone for 'Low T' and research evidence on effects of advertising targeting the public highlights the need for improved regulation of unbranded 'disease awareness' advertising to ensure adequate protection of public.

Proper staging is critical to the management of pancreatic ductal carcinoma (PDAC). Laparoscopy has been used to stage patients without gross metastatic disease with variable success. We aimed to identify the frequency of patients diagnosed by laparoscopy with occult metastatic disease. Also, we looked for variables related to a higher chance of occult metastasis. Patients with PDAC submitted to staging laparoscopy either immediately before pancreatectomy or as a separate procedure between January 2010 and December 2016 were included. None presented gross metastatic disease at initial staging. We used logistic regression to search for variables associated with metastatic disease. The study population consisted of 63 patients. Among all patients, nine (16.7%) had occult metastases at laparoscopy. Unresectable tumor (Odds ratio = 18.0, P = 0.03), increasing tumor size (Odds ratio = 1.36, P = 0.01), and abdominal pain (Odds ratio = 5.6, P = 0.04) significantly predicted the risk of occult metastases in univariate analysis. In multivariate analysis, only tumor size predicted the risk of occult metastases. Laparoscopy remains a valuable tool in PDAC staging. Patients with either large or unresectable tumors, or presenting with abdominal pain present the highest risk for occult intra-abdominal metastases. © 2018 Wiley Periodicals, Inc.

Proliferative kidney disease in brown trout: infection level, pathology and mortality under field conditions.

Schmidt-Posthaus, Heike; Hirschi, Regula; Schneider, Ernst

2015-05-21

Proliferative kidney disease (PKD) is an emerging disease threatening wild salmonid populations. In temperature-controlled aquaria, PKD can cause mortality rates of up to 85% in rainbow trout. So far, no data about PKD-related mortality in wild brown trout Salmo trutta fario are available. The aim of this study was to investigate mortality rates and pathology in brown trout kept in a cage within a natural river habitat known to harbor Tetracapsuloides bryosalmonae. Young-of-the-year (YOY) brown trout, free of T. bryosalmonae, were exposed in the River Wutach, in the northeast of Switzerland, during 3 summer months. Samples of wild brown trout caught by electrofishing near the cage location were examined in parallel. The incidence of PKD in cage-exposed animals (69%) was not significantly different to the disease prevalence of wild fish (82 and 80% in the upstream and downstream locations, respectively). The mortality in cage-exposed animals, however, was as low as 15%. At the termination of the exposure experiment, surviving fish showed histological lesions typical for PKD regression, suggesting that many YOY brown trout survive the initial infection. Our results at the River Wutach suggest that PKD in brown trout does not always result in high mortality under natural conditions.

Alzheimer’s disease (AD) involves a gradual breakdown of brain connectivity, and network analyses offer a promising new approach to track and understand disease progression. Even so, our ability to detect degenerative changes in brain networks depends on the methods used. Here we compared several tractography and feature extraction methods to see which ones gave best diagnostic classification for 202 people with AD, mild cognitive impairment or normal cognition, scanned with 41-gradient diffusion-weighted magnetic resonance imaging as part of the Alzheimer’s Disease Neuroimaging Initiative (ADNI) project. We computed brain networks based on whole brain tractography with nine different methods – four of them tensor-based deterministic (FACT, RK2, SL, and TL), two orientation distribution function (ODF)-based deterministic (FACT, RK2), two ODF-based probabilistic approaches (Hough and PICo), and one “ball-and-stick” approach (Probtrackx). Brain networks derived from different tractography algorithms did not differ in terms of classification performance on ADNI, but performing principal components analysis on networks helped classification in some cases. Small differences may still be detectable in a truly vast cohort, but these experiments help assess the relative advantages of different tractography algorithms, and different post-processing choices, when used for classification.

The surgical treatment of comorbid erectile dysfunction and Peyronie's disease has long included the implantation of an inflatable penile prosthesis as well as a number of adjuvant maneuvers to address residual curvature after prosthesis placement. To review the various surgical options for addressing curvature after prosthesis placement, with specific attention paid to an original article by Wilson et al. reporting on modeling over a penile prosthesis for the management of Peyronie's disease. A literature review was performed analyzing articles reporting the management of penile curvature in patients undergoing implantation of an inflatable penile prosthesis. Reported improvement in Peyronie's deformity as well as the complication rate associated with the various surgical techniques described. Modeling is a well-established treatment modality among patients with Peyronie's disease undergoing penile prosthesis implantation. A variety of other adjuvant maneuvers to address residual curvature when modeling alone is insufficient has been presented in the literature. Over 20 years of experience with modeling over a penile prosthesis have proven the efficacy and safety of this treatment option, providing the surgeon a simple initial step for the management of residual curvature after penile implantation which allows for the use of additional adjuvant maneuvers in those with significant deformities. © 2015 International Society for Sexual Medicine.

Patients experience extreme difficulty when facing an intractable genetic disease. Herein, we examine the experiences of patients with Duchenne muscular dystrophy in facing and learning about their disease. A total of seven patients with Duchenne muscular dystrophy (age range: 20-48) participated. We conducted in-depth interviews with them about how they learned of their disease and how their feelings regarding the disease changed over time. Transcribed data were analysed using thematic analysis. The following themes emerged from this analysis: "experiences before receiving the diagnosis," "experiences when they learned of their condition and progression of the disease," "supports," and "desired explanations." Anxiety and worry were most pronounced when they had to transition to using wheelchairs or respirators due to disease progression; indeed, such transitions affect the patients psychological adjustment. In such times, support from significant others in their lives helped patients adjust.

Large-vessel thrombosis in intestinal Behçet's disease complicated with myelodysplastic syndrome and trisomy 8.

PubMed

Chen, Huang-Chi; Chiu, Ying-Ming

2012-03-14

Behçet's disease is characterized by recurrent oral ulcers, genital ulcers, uveitis and skin lesions. Myelodysplastic syndrome (MDS) is characterized by problems due to ineffective hematopoiesis. Several studies have identified a relationship between MDS and Behçet's disease, especially intestinal Behçet's disease. Trisomy 8 seems to play an important role in these disorders as well. The present case was a 24-year-old woman who had a huge tonsil ulcer with initial symptoms of odynophagia and intermittent fever. We also noted folliculitis on her upper back. Five days later, she began to experience diarrhea and abdominal pain. Abdominal computed tomography and subsequent surgery revealed ileum perforation and enterocolitis with multiple ulcers. Later, she was admitted again for a vulvar suppurative ulcer and suspicious Bartholin's cyst infection. The patient's clinical presentations met the criteria for Behçet's disease. Six months after the bowel perforation event, we noted the development of pancytopenia in a routine laboratory examination. All the examinations led to the diagnosis of MDS with trisomy 8. The most unusual finding was that multiple large vessel thrombi developed during follow-up. Previous studies have suggested that trisomy 8 in MDS leads to concurrent intestinal Behçet's disease. Moreover, the inflammatory and immune genes related to thrombus formation are overexpressed in cases of MDS with trisomy 8. Trisomy 8 must play a role in thrombosis. Further studies are needed to help clarify the pathophysiology and pathogenesis of these disorders.

High amount of dietary fiber not harmful but favorable for Crohn disease.

Current chronic diseases are a reflection of the westernized diet that features a decreased consumption of dietary fiber. Indigestible dietary fiber is metabolized by gut bacteria, including Faecalibacterium prausnitzii, to butyrate, which has a critical role in colonic homeostasis owing to a variety of functions. Dietary fiber intake has been significantly inversely associated with the risk of chronic diseases. Crohn disease (CD) is not an exception. However, even authors who reported the inverse association between dietary fiber and a risk of CD made no recommendation of dietary fiber intake to CD patients. Some correspondence was against advocating high fiber intake in CD. We initiated a semivegetarian diet (SVD), namely a lacto-ovo-vegetarian diet, for patients with inflammatory bowel disease. Our SVD contains 32.4 g of dietary fiber in 2000 kcal. There was no untoward effect of the SVD. The remission rate with combined infliximab and SVD for newly diagnosed CD patients was 100%. Maintenance of remission on SVD without scheduled maintenance therapy with biologic drugs was 92% at 2 years. These excellent short- and long-term results can be explained partly by SVD. The fecal bacterial count of F prausnitzii in patients with CD is significantly lower than in healthy controls. Diet reviews recommend plant-based diets to treat and to prevent a variety of chronic diseases. SVD belongs to plant-based diets that inevitably contain considerable amounts of dietary fiber. Our clinical experience and available data provide a rationale to recommend a high fiber intake to treat CD.

The AFHSC-Division of GEIS Operations Predictive Surveillance Program: a multidisciplinary approach for the early detection and response to disease outbreaks

PubMed Central

2011-01-01

The Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System Operations (AFHSC-GEIS) initiated a coordinated, multidisciplinary program to link data sets and information derived from eco-climatic remote sensing activities, ecologic niche modeling, arthropod vector, animal disease-host/reservoir, and human disease surveillance for febrile illnesses, into a predictive surveillance program that generates advisories and alerts on emerging infectious disease outbreaks. The program’s ultimate goal is pro-active public health practice through pre-event preparedness, prevention and control, and response decision-making and prioritization. This multidisciplinary program is rooted in over 10 years experience in predictive surveillance for Rift Valley fever outbreaks in Eastern Africa. The AFHSC-GEIS Rift Valley fever project is based on the identification and use of disease-emergence critical detection points as reliable signals for increased outbreak risk. The AFHSC-GEIS predictive surveillance program has formalized the Rift Valley fever project into a structured template for extending predictive surveillance capability to other Department of Defense (DoD)-priority vector- and water-borne, and zoonotic diseases and geographic areas. These include leishmaniasis, malaria, and Crimea-Congo and other viral hemorrhagic fevers in Central Asia and Africa, dengue fever in Asia and the Americas, Japanese encephalitis (JE) and chikungunya fever in Asia, and rickettsial and other tick-borne infections in the U.S., Africa and Asia.

Winning and positive affect can lead to reckless gambling.

Experiments 1 and 2 examined whether winning versus losing led to reckless betting for real prize money. Experiment 2 also assessed whether positive or negative emotions were linked to such reckless betting. College students were randomly assigned to experience primarily either wins or losses during the rigged first round of a computerized card tournament that had 2 independent rounds. For the second round, participants' chip totals were reset and cards were dealt randomly. In Experiment 1 (N=107), participants in the Initial-Winning, as compared with the Initial-Losing, condition bet more recklessly (i.e., bet too many chips when a loss was likely). Experiment 2 (N=72) again showed that Initial-Winning participants bet significantly more recklessly than did Initial-Losing participants. It also revealed that positive affect was significantly positively correlated with such reckless betting. These findings have implications for understanding how college students, those at an age when they are especially vulnerable to problem gambling, can come to lose more money than they can afford. Initially winning and positive affect when gambling could be risk factors. Copyright (c) 2009 APA, all rights reserved.

Heart failure guidelines recommend routine monitoring of serum potassium, and renal function in patients treated with a mineralocorticoid receptor antagonist (MRA). How these recommendations are implemented in high-risk patients or according to setting of drug initiation is poorly characterized. We conducted a retrospective cohort study of Medicare beneficiaries linked to laboratory data in 10 states with prevalent heart failure as of July 1, 2011, and incident MRA use between May 1 and September 30, 2011. Outcomes included laboratory testing before MRA initiation and in the early (days 1-10) and extended (days 11-90) post-initiation periods, based on setting of drug initiation and the presence of renal insufficiency. Additional outcomes included abnormal laboratory results and adverse events proximate to MRA initiation. Of 10 443 Medicare beneficiaries with heart failure started on an MRA, 19.7% were initiated during a hospitalization. Appropriate follow-up laboratory testing across all time periods occurred in 25.2% of patients with inpatient initiation compared with 2.8% of patients begun as an outpatient. Patients with chronic kidney disease had higher rates of both hyperkalemia and acute kidney failure in the early (1.3% and 2.7%, respectively) and extended (5.6% and 9.8%, respectively) post-initiation periods compared with those without chronic kidney disease. Patients initiated on MRA therapy as an outpatient had extremely poor rates of guideline indicated follow-up laboratory monitoring after drug initiation. In particular, patients with chronic kidney disease are at high risk for adverse events after MRA initiation. Quality improvement initiatives focused on systems to improve appropriate laboratory monitoring are needed. © 2017 American Heart Association, Inc.

Pigmented extramammary Paget’s disease of the axilla mimicking melanoma: case report and review of the literature

Pigmented Paget’s disease is a rare variant which is often confused clinically and histologically with melanoma in situ. Herein, we describe a case of pigmented extramammary Paget’s disease involving the axilla of a 79 year old white male thought initially to represent malignant melanoma clinically and histologically. Review of the literature reveals that pigmented variant of Paget’s disease, either mammary or extramammary, could be initially misdiagnosed as melanoma unless this entity is considered in the differential diagnosis and additional confirmatory studies are performed.

Tumour-initiating cells capable of self-renewal and differentiation, which are responsible for tumour growth, have been identified in human haematological malignancies and solid cancers. If such minority populations are associated with tumour progression in human patients, specific targeting of tumour-initiating cells could be a strategy to eradicate cancers currently resistant to systemic therapy. Here we identify a subpopulation enriched for human malignant-melanoma-initiating cells (MMIC) defined by expression of the chemoresistance mediator ABCB5 (refs 7, 8) and show that specific targeting of this tumorigenic minority population inhibits tumour growth. ABCB5+ tumour cells detected in human melanoma patients show a primitive molecular phenotype and correlate with clinical melanoma progression. In serial human-to-mouse xenotransplantation experiments, ABCB5+ melanoma cells possess greater tumorigenic capacity than ABCB5- bulk populations and re-establish clinical tumour heterogeneity. In vivo genetic lineage tracking demonstrates a specific capacity of ABCB5+ subpopulations for self-renewal and differentiation, because ABCB5+ cancer cells generate both ABCB5+ and ABCB5- progeny, whereas ABCB5- tumour populations give rise, at lower rates, exclusively to ABCB5- cells. In an initial proof-of-principle analysis, designed to test the hypothesis that MMIC are also required for growth of established tumours, systemic administration of a monoclonal antibody directed at ABCB5, shown to be capable of inducing antibody-dependent cell-mediated cytotoxicity in ABCB5+ MMIC, exerted tumour-inhibitory effects. Identification of tumour-initiating cells with enhanced abundance in more advanced disease but susceptibility to specific targeting through a defining chemoresistance determinant has important implications for cancer therapy.

Objective Even when initially successful, many interventions aimed at reducing the toll of water-related infectious disease have not been sustainable over longer periods of time. Here we review historical practices in water-related infectious disease research and propose an interdisciplinary public health oriented systems approach to research and intervention design. Data sources On the basis of the literature and the authors’ experiences, we summarize contributions from key disciplines and identify common problems and trends. Practices in developing countries, where the disease burden is the most severe, are emphasized. Data extraction We define waterborne and water-associated vectorborne diseases and identify disciplinary themes and conceptual needs by drawing from ecologic, anthropologic, engineering, political/economic, and public health fields. A case study examines one of the classes of water-related infectious disease. Data synthesis The limited success in designing sustainable interventions is attributable to factors that include the complexity and interactions among the social, ecologic, engineering, political/economic, and public health domains; incomplete data; a lack of relevant indicators; and most important, an inadequate understanding of the proximal and distal factors that cause water-related infectious disease. Fundamental change is needed for research on water-related infectious diseases, and we advocate a systems approach framework using an ongoing evidence-based health outcomes focus with an extended time horizon. The examples and case study in the review show many opportunities for interdisciplinary collaborations, data fusion techniques, and other advances. Conclusions The proposed framework will facilitate research by addressing the complexity and divergent scales of problems and by engaging scientists in the disciplines needed to tackle these difficult problems. Such research can enhance the prevention and control of water-related infectious diseases in a manner that is sustainable and focused on public health outcomes. PMID:19654908

The social course of drug injection and sexual activity among YMSM and other high-risk youth: an agenda for future research.

PubMed

Clatts, Michael C; Goldsamt, Lloyd; Neaigus, Alan; Welle, Dorinda L

The cumulative epidemiologic literature indicates that many injecting drug users (IDUs) initiate injection as a mode of drug administration during late adolescence or early adulthood. Recent studies have shown that IDUs are often exposed to viral infections relatively early in the course of injection, highlighting the importance of understanding this initiation process for both epidemiology and prevention. Epidemiologic evidence similarly suggests that at least some youth populations, most notably young men who have sex with men (YMSM), are at substantial risk for exposure to HIV and other sexually transmitted diseases (STDs) from early sexual activity. Despite the importance of this issue for both epidemiology and prevention, however, surprisingly little information is available on the social course of injection initiation, including the individual, social, or ecological factors that might mitigate or exacerbate transmission risks within the critical phase of early injection drug use. Similarly, we know little about the ways that YMSM and other high-risk youth understand risk, the kinds of exchanges and relationships in which they participate in the context of initiating sexual activity, or how drug use is operant in these exchanges and early sexual experiences. In this article, we explore key dimensions of the early initiation of injection and sexual risk, and discuss how a social network approach might be instrumental in understanding the social course of drug injection and sexual activities among youth and young adult populations.

Type 2 diabetes mellitus is a progressive condition in which the pancreatic beta-cell function deteriorates with increasing duration of the disease. When good glycaemic control is not achieved despite adherence to oral hypoglycaemic drugs, healthy diet and lifestyle, insulin should be initiated. However, this is often delayed due to various reasons. We aimed to determine the issues relating to insulin initiation for diabetic patients managed in primary care polyclinics in Singapore. Qualitative data was obtained during four focus group discussions, with participation from healthcare professionals (HCPs), including physicians and nurses, and type 2 diabetes mellitus patients. The data was transcribed into text, coded and grouped into themes. Launching the topic and doctor-patient communication on insulin therapy were key issues in insulin initiation. Patient barriers to insulin commencement included: refusal to acknowledge the need for insulin therapy; its perception as a social stigma, an inconvenient mode of treatment or punishment for failure; and fear of needles, side-effects and complications. The HCP's attitude and experience with insulin therapy were also possible barriers. Our findings highlight that insulin initiation is affected by the complex interaction between the patients and HCPs, and other system factors. Patients may harbour misconceptions about insulin due to the late introduction of insulin therapy by HCPs or the way the therapy is being communicated to them. The key issues to address are the disparity in perceptions of diabetic control between HCPs and patients, and education regarding the need for insulin therapy.

Cardiovascular diseases were the leading cause of death in women in the United Arab Emirates (UAE) in 2010. The UAE is expected to experience a tripling of heart diseases in the next two decades as risk factors for heart diseases increase. Research shows that first year survival rates of younger women suffering from a heart attack are lower than in men. Women present with a wider range of symptoms for heart diseases than men; non-recognition of atypical symptoms may explain the delay in seeking treatment and poor prognosis following heart diseases in women. No known study on awareness of heart diseases among women has been carried out in the Middle Eastern region. Social constructionist and interpretivist epistemological approaches have been considered in this qualitative study to explore the awareness of heart diseases and the health seeking behavior of Emirati women. Convenience sampling was used to recruit 41 Emirati women. Three focus groups and six in-depth semi-structured interviews were conducted to obtain data. Thematic content analysis was applied to the data following transcription and translation of recordings. Emirati women had limited knowledge on heart diseases. Women were generally unaware of the atypical symptoms, commonly experienced by women however they identified most risk factors associated with heart diseases. Lack of awareness of disease severity and symptoms, sociocultural influences and distrust in the healthcare system were considered the main barriers to seeking prompt treatment. This study clearly identified gaps and inaccuracies in knowledge of heart diseases, which could contribute to delayed health seeking action and possibly poorer prognosis among Emirati women. Absence of initiatives to educate women on cardiovascular diseases in UAE has erroneously deemed it a less serious concern among Emirati women. The findings from this study provide clear indications of the need to increase accountability of the healthcare system and to develop culturally relevant, gender specific, age focused, heart diseases related public health awareness campaigns in UAE.

In the pathogenesis of central nervous system (CNS) demyelinating disorders, antigen-specific B cells are implicated to act as potent antigen-presenting cells (APC), eliciting waves of inflammatory CNS infiltration. Here, we provide the first evidence that CNS-reactive antibodies (Ab) are similarly capable of initiating an encephalitogenic immune response by targeting endogenous CNS antigen to otherwise inert myeloid APC. In a transgenic mouse model, constitutive production of Ab against myelin oligodendrocyte glycoprotein (MOG) was sufficient to promote spontaneous experimental autoimmune encephalomyelitis (EAE) in the absence of B cells, when mice endogenously contained MOG-recognizing T cells. Adoptive transfer studies corroborated that anti-MOG Ab triggered activation and expansion of peripheral MOG-specific T cells in an Fc-dependent manner, subsequently causing EAE. To evaluate the underlying mechanism, anti-MOG Ab were added to a co-culture of myeloid APC and MOG-specific T cells. At otherwise undetected concentrations, anti-MOG Ab enabled Fc-mediated APC recognition of intact MOG; internalized, processed and presented MOG activated naïve T cells to differentiate in an encephalitogenic manner. In a series of translational experiments, anti-MOG Ab from two patients with an acute flare of CNS inflammation likewise facilitated detection of human MOG. Jointly, these observations highlight Ab-mediated opsonization of endogenous CNS auto-antigen as a novel disease- and/or relapse-triggering mechanism in CNS demyelinating disorders.

The hippocampus has been known to be an important structure as a biomarker for Alzheimer's disease (AD) and other neurological and psychiatric diseases. However, it requires accurate, robust and reproducible delineation of hippocampal structures. In this study, an automated hippocampal segmentation method based on a graph-cuts algorithm combined with atlas-based segmentation and morphological opening was proposed. First of all, the atlas-based segmentation was applied to define initial hippocampal region for a priori information on graph-cuts. The definition of initial seeds was further elaborated by incorporating estimation of partial volume probabilities at each voxel. Finally, morphological opening was applied to reduce false positive of the result processed by graph-cuts. In the experiments with twenty-seven healthy normal subjects, the proposed method showed more reliable results (similarity index=0.81±0.03) than the conventional atlas-based segmentation method (0.72±0.04). Also as for segmentation accuracy which is measured in terms of the ratios of false positive and false negative, the proposed method (precision=0.76±0.04, recall=0.86±0.05) produced lower ratios than the conventional methods (0.73±0.05, 0.72±0.06) demonstrating its plausibility for accurate, robust and reliable segmentation of hippocampus.

This survey compared surgical management of Hirschsprung's disease (HD) and anorectal malformations (ARM) in high and low resource settings. An online survey was sent to 208 members of the Canadian Association of Paediatric Surgeons (CAPS) and the Association of Paediatric Surgeons of Nigeria (APSON). The response rate was 76.8% with 127 complete surveys (APSON 34, CAPS 97). Only 29.5% of APSON surgeons had frozen section available for diagnosis of HD. They were more likely to choose full thickness rectal biopsy (APSON 70.6% vs. CAPS 9.4%, P < 0.05) and do an initial colostomy for HD (APSON 23.5% vs. CAPS 0%, P < 0.05). Experience with trans-anal pull-through for HD was similar in both groups (APSON 76.5%, CAPS 66.7%). CAPS members practising in the United States were more likely to perform a one-stage pull-through for HD during the initial hospitalization (USA 65.4% vs. Canada 28.3%, P < 0.05). The frequency of colostomy in females with vestibular fistula varied widely independent of geography. APSON surgeons were less likely to have enterostomal therapists and patient education resources. Local resources which vary by geographic location affect the management of HD and ARM including colostomy. Collaboration between CAPS and APSON members could address resource and educational needs to improve patient care.

Objective: Comorbidities are common in multiple sclerosis (MS) and adversely affect health outcomes. However, the effect of comorbidity on treatment decisions in MS remains unknown. We aimed to examine the effects of comorbidity on initiation of injectable disease-modifying therapies (DMTs) and on the choice of the initial DMT in MS. Methods: We conducted a retrospective observational analysis using population-based health administrative and linked clinical databases in 3 Canadian provinces. MS cases were defined as any individual with ≥3 diagnostic codes for MS. Cohort entry (index date) was the first recorded demyelinating disease-related claim. The outcomes included choice of initial first-line DMTs and time to initiating a DMT. Logistic and Cox regression models were used to examine the association between comorbidity status and study outcomes, adjusting for sex, age, year of index date, and socioeconomic status. Meta-analysis was used to estimate overall effects across the 3 provinces. Results: We identified 10,698 persons with incident MS, half of whom had ≥1 comorbidities. As the total number of comorbidities increased, the likelihood of initiating a DMT decreased. Comorbid anxiety and ischemic heart disease were associated with reduced initiation of a DMT. However, patients with depression were 13% more likely to initiate a DMT compared to those without depression at the index date (adjusted hazard ratio 1.13; 95% confidence interval 1.00–1.27). Conclusions: Comorbidities are associated with treatment decisions regarding DMTs in MS. A better understanding of the effects of comorbidity on effectiveness and safety of DMTs is needed.

Background Paradoxical kinesis has been observed in bradykinetic people with Parkinson’s disease. Paradoxical kinesis occurs in situations where an individual is strongly motivated or influenced by relevant external cues. Our aim was to induce paradoxical kinesis in the laboratory. We tested whether the motivation of avoiding a mild electric shock was sufficient to induce paradoxical kinesis in externally-triggered and self-initiated conditions in people with Parkinson’s disease tested on medication and in age-matched controls. Methods Participants completed a shock avoidance behavioural paradigm in which half of the trials could result in a mild electric shock if the participant did not move fast enough. Half of the trials of each type were self-initiated and half were externally-triggered. The criterion for avoiding shock was a maximum movement time, adjusted according to each participant’s performance on previous trials using a staircase tracking procedure. Results On trials with threat of shock, both patients with Parkinson’s disease and controls had faster movement times compared to no potential shock trials, in both self-initiated and externally-triggered conditions. The magnitude of improvement of movement time from no potential shock to potential shock trials was positively correlated with anxiety ratings. Conclusions When motivated to avoid mild electric shock, patients with Parkinson’s disease, similar to healthy controls, showed significant speeding of movement execution. This was observed in both self-initiated and externally-triggered versions of the task. Nevertheless, in the ET condition the improvement of reaction times induced by motivation to avoid shocks was greater for the PD patients than controls, highlighting the value of external cues for movement initiation in PD patients. The magnitude of improvement from the no potential shock to the potential shock trials was associated with the threat-induced anxiety. This demonstration of paradoxical kinesis in the laboratory under both self-initiated and externally-triggered conditions has implications for motivational and attentional enhancement of movement speed in Parkinson’s disease.

The Safe Motherhood Research Project studies the implementation and scale-up of maternal, newborn and child health (MNCH) initiatives in Jimma Zone, Ethiopia. This qualitative rapid assessment study was undertaken to explore community perceptions and experiences related to health, health inequality and other MNCH themes. We conducted 12 focus group discussions and 24 in-depth interviews with community stakeholder groups (female and male community members, Health Extension Workers, members of the Women Development Army and Male Development Army, and religious leaders) across six rural sites in Jimma Zone. Data were analyzed through thematic coding and the preparation of content summaries by theme. Participants described being healthy as being disease free, being able to perform daily activities and being able to pursue broad aspirations. Health inequalities were viewed as community issues, primarily emanating from a lack of knowledge or social exclusion. Poverty was raised as a possible contributor to poor health, however, participants felt this could be overcome through community-level responses. Participants described formal and informal mechanisms for supporting the disadvantaged, which served as a type of safety net, providing information as well as emotional, financial and social support. Understanding community perceptions of health and health inequality can serve as an evidence base for community-level initiatives, including MNCH promotion. The findings of this study enable the development of audience-centered MNCH promotion activities that closely align with community priorities and experiences. This research demonstrates the application of rapid qualitative assessment methods to explore the context for MNCH promotion activities.

Despite proof of voluntary counseling and testing (VCT) effectiveness in HIV disease prevention and management, there are limited reports on experience with pre- and post-HIV-test counseling in developing countries. In view of this, we aimed to bring to the fore the voluntary counseling and testing experience at a tertiary healthcare center. The present study was conducted at the voluntary counseling and testing center of a tertiary healthcare center and the National HIV Reference Center. Participants were 1169 men and 581 females attending the VCT clinic from February 2005 to March 2006. Odds ratios were calculated for each of the variable to analyze the strength of association with HIV sero-status. Out of 1750 patients, 322 (27.5%) males and 156 females (26.9%) tested HIV-positive. HIV-sero-positivity was observed to be associated to participant age (approximately 1.5 for 25-44 yrs age group), marital status (2.3 times in married patients), primary or lower education level (1.5 times), citing spouse death/HIV-infected spouse as the reason for seeking VCT (2.2 times) and reporting a history of risk behavior as reason for getting tested. This study aims to evaluate the effectiveness of existing client initiated voluntary counseling and testing facility in the light of a recent recommendation by WHO/UNAIDS for the implementation of provider initiated voluntary counseling services. Through this study, we could also highlight socio-demographic factors, like education and age, and reasons stated by participants for seeking VCT, which were associated with HIV-positive status and put an individual at a higher risk of HIV infection.

2009-01-01

In 2006, New York City's Health Department amended the city Health Code to require the posting of calorie counts by chain restaurants on menus, menu boards, and item tags. This was one element of the city's response to rising obesity rates. Drafting the rule involved many decisions that affected its impact and its legal viability. The restaurant industry argued against the rule and twice sued to prevent its implementation. An initial version of the rule was found to be preempted by federal law, but a revised version was implemented in January 2008. The experience shows that state and local health departments can use their existing authority over restaurants to combat obesity and, indirectly, chronic diseases.

Recently kidney transplantation has become an accepted treatment modality for the treatment of HIV infected patients with end-stage renal diseases. For such treatment it is required stability of clinical and laboratory parameters related to HIV infection and the use of highly active antiretroviral therapy. In this report we present the first two cases in Brazil of patients with HIV infection transplanted with organs from deceased donors performed successfully in our institution. The interactions between immunosuppressive and antiretroviral drugs, the co-infections, cardiovascular risk profile and the high incidence of acute rejection remain the major problems to be dealt with in these patients.

2014-11-01

Multiple symmetric lipomatosis (MSL) is a rare disease of unknown etiology, characterized by the presence of multiple, symmetrical, noncapsulated lipomas, mostly in the neck and upper trunk. To date, there is no effective medical treatment of MSL. Surgical treatment is based on 2 options, namely, lipectomy and/or liposuction. In this retrospective study, we compare traditional lipectomy with ultrasound-assisted liposuction. Our initial experience demonstrates that the ultrasound-assisted liposuction procedure can be applied to patients with MSL, allowing simultaneous treatment of multiple areas in a single session and the removal of a substantial amount of fat, thus improving aesthetic results. If lipomas are circumscribed and isolated, traditional lipectomy is probably to be preferred.

Workshop on Spaceflight Alterations in Host-Microorganism Interactions

NASA Technical Reports Server (NTRS)

Ott, C. Mark

2010-01-01

On June 11, 2009, a workshop that included internal and external experts was convened to determine the risk of changes in microorganisms that could alter host-microorganism interactions during a mission. The evidence is based in part on multiple flight experiments which indicate altered virulence in Salmonella typhimurium when cultured in flight. The workshop participants were tasked to determine if adequate information was available to initiate changes in NASA's current approach to infectious disease risk assessment and medical operations. The consensus of the participants is that the current evidence was not adequate to provide direction for operational changes; however, the evidence is compelling and clearly indicates that changes to microorganisms were occurring during spaceflight and further research is required.

In many countries, decisions about the public funding of drugs are preferentially based on the results of randomized trials. For truly rare diseases, such trials are not typically available, and approaches by public payers are highly variable. In view of this, a policy framework intended to fairly evaluate these drugs was developed by the Drugs for Rare Diseases Working Group (DRDWG) at the request of the Ontario Public Drug Programs. To report the initial experience of applying a novel evaluation framework to funding applications for drugs for rare diseases. Retrospective observational cohort study. Clinical effectiveness, costs, funding recommendations, funding approval. Between March 2008 and February 2013, eight drugs were evaluated using the DRDWG framework. The estimated average annual drug cost per patient ranged from 28,000 to 1,200,000 Canadian dollars (CAD). For five drugs, full evaluations were completed, specific funding recommendations were made by the DRDWG, and funding was approved after risk-sharing agreements with the manufacturers were negotiated. For two drugs, the disease indications were determined to be ineligible for consideration. For one drug, there was insufficient natural history data for the disease to provide a basis for recommendation. For the five drugs fully evaluated, 32 patients met the predefined eligibility criteria for funding, and five were denied based on predefined exclusion criteria. The framework improved transparency and consistency for evaluation and public funding of drugs for rare diseases in Ontario. The evaluation process will continue to be iteratively refined as feedback on actual versus expected clinical and economic outcomes is incorporated.

Despite the compelling evidence supporting cardiovascular medications in the secondary prevention of coronary artery disease, many patients discontinue treatment. In this synthesis, we sought to understand from a patient perspective the factors that promote medication persistence. We systematically searched 7 databases (MEDLINE, Embase, PsycINFO, SCOPUS, CINAHL, ASSIA, and SSCI) for published qualitative research about the medication-taking experiences of patients with coronary artery disease and their partners. Articles were assessed for quality using a modified CASP (Critical Appraisal Skills Programme) checklist. Synthesis was undertaken using well-established meta-ethnographic approaches. We included 17 articles in the final synthesis from the United Kingdom (6), Europe (5), United States (4), China (1), and Australia (1), with a total sample size of 391 patients. Analyses suggested that some patients hold fatalistic beliefs about their disease, whereas others believe they have been cured by interventions; both can lead to failure to take medication. Patients who adapt to being a "heart patient" are positive about medication taking. Some individuals dislike taking tablets generally and are wary of long-term effects. Relationships with prescribing clinicians are of critical importance for patients, with inaccessibility and insensitive terminology negatively affecting patients' perceptions about treatments. Strategies to promote higher persistence of secondary prevention medications in patients with coronary artery disease need to recognize the key role of the prescribing clinician. Providing medication-specific information at the time of initiating therapy, improving the transition between secondary and primary care, and explaining the risk of disease recurrence may all help to modify patient attitudes toward drugs to prevent further cardiovascular disease.

Multidisciplinary treatment guidelines for Dupuytren disease can aid in optimizing the quality of care for patients with this disorder. Therefore, this study aimed to achieve consensus on a multidisciplinary treatment guideline for Dupuytren disease. A European Delphi consensus strategy was initiated. A systematic review reporting on the effectiveness of interventions was conducted and used as an evidence-based starting point for this study. In total, 39 experts (hand surgeons, hand therapists, and physical medicine and rehabilitation physicians) participated in the Delphi consensus strategy. Each Delphi round consisted of a questionnaire, an analysis, and a feedback report. After four Delphi rounds, consensus was achieved on the description, symptoms, and diagnosis of Dupuytren disease. No nonsurgical interventions were included in the guideline. Needle and open fasciotomy, and a limited fasciectomy and dermofasciectomy, were seen as suitable surgical techniques for Dupuytren disease. Factors relevant for choosing one of these surgical techniques were identified and divided into patient-related (age, comorbidity), disease-related (palpable cord, previous surgery in the same area, skin involvement, time of recovery, recurrences), and surgeon-related (years of experience) factors. Associations of these factors with the choice of a specific surgical technique were reported in the guideline. Postsurgical rehabilitation should always include instructions and exercise therapy; postsurgical splinting should be performed on indication. Relevant details for the use of surgical and postsurgical interventions were described. This treatment guideline is likely to promote further discussion on related clinical and scientific issues and may therefore contribute to better treatment of patients with Dupuytren disease.

A polymeric diet rich in transforming growth factor-beta 2 used as a single nutrient has been shown to induce remission in 79% of children with Crohn's disease. To summarize the experience of several pediatric gastroenterology units in Israel using a TGFbeta2-enriched polymeric diet (Modulen IBD) supplementation in children and adolescents with Crohn's disease. In a retrospective study we reviewed the charts of 28 children with Crohn's disease (10 girls, 18 boys) who received, in addition to conventional treatment, Modulen IBD as a supplement to their regular nutrition. These children were compared with 18 children supplemented with standard polymeric formula (Ensure Plus) and 18 children without formula supplementation. We recorded clinical manifestations, growth, and the Pediatric Crohn's Disease Activity Index before and after initiation of the polymeric diet. The Modulen-treated children showed a significant decrease in PCDAI from 34.3 to 15.7 (P< 0.0001). A significant decrease in PCDAI was recorded also in the Ensure Plus group, from 35 to 22 (P= 0.02) but not in the non-supplemented group. Significant improvements in body mass index (P = 0.01) and erythrocyte sedimentation rate (P= 0.03) were recorded at follow-up (median 3.4 months) only in the Modulen IBD group. In this cohort of children with Crohn's disease, supplementation of the diet with Modulen IBD as well as supplementation with Ensure Plus was associated with a decrease in PCDAI. The children supplemented with Modulen IBD also showed improvement in BMI, suggesting an additional advantage of nutritional therapy in children with this disease.

Abstract Background: Emergency departments (EDs) are seeing more patients with palliative care (PC) needs, but evidence on best practice is scarce. Objectives: To examine the effectiveness of ED-based PC interventions on hospital admissions (primary outcome), length of stay (LOS), symptoms, quality of life, use of other health care services, and PC referrals for adults with advanced disease. Methods: We searched five databases until August 2014, checked reference lists/conference abstracts, and contacted experts. Eligible studies were controlled trials, pre-post studies, cohort studies, and case series reporting outcomes of ED-based PC. Results: Five studies with 4374 participants were included: three case series and two cohort studies. Interventions included a screening tool, traditional ED-PC, and integrated ED-PC. Two studies reported on hospital admissions: in one study there was no statistically significant difference in 90-day readmission rates between patients who initiated integrated PC at the ED (11/50 patients, 22%) compared to those who initiated PC after hospital admission (179/1385, 13%); another study showed a high admission rate (90%) in 14 months following ED-PC, but without comparison. One study showed an LOS reduction (mean 4.32 days in ED-initiated PC group versus 8.29 days in postadmission-initiated group; p < 0.01). There was scarce evidence on other outcomes except for conflicting findings on survival: in one study, ED-PC patients were more likely to experience an interval between ED presentation and death >9 hours (OR 2.75, 95% CI 2.21–3.41); another study showed increased mortality risk in the intervention group; and a case series described a higher in-hospital death rate when PC was ED-initiated (62%), compared to ward (16%) or ICU (50%) (unknown p-value). Conclusions: There is yet no evidence that ED-based PC affects patient outcomes except for indication from one study of no association with 90-day hospital readmission but a possible reduction in LOS if integrated PC is introduced early at ED rather than after hospital admission. There is an urgent need for trials to confirm these findings alongside other potential benefits and survival effects. PMID:27115914

A better understanding of the natural history of osteogenesis imperfecta (OI) in adulthood should improve health care for patients with this rare condition. The Osteogenesis Imperfecta Foundation established the Adult Natural History Initiative (ANHI) in 2010 to give voice to the health concerns of the adult OI community and to begin to address existing knowledge gaps for this condition. Using a web-based platform, 959 adults with self-reported OI, representing a wide range of self-reported disease severity, reported symptoms and health conditions, estimated the impact of these concerns on present and future health-related quality of life (QoL) and completed a Patient-Reported Outcomes Measurement Information System (PROMIS®) survey of health issues. Adults with OI report lower general physical health status (p < .0001), exhibit a higher prevalence of auditory (58% of sample versus 2-16% of normalized population) and musculoskeletal (64% of sample versus 1-3% of normalized population) concerns than the general population, but report generally similar mental health status. Musculoskeletal, auditory, pulmonary, endocrine, and gastrointestinal issues are particular future health-related QoL concerns for these adults. Numerous other statistically significant differences exist among adults with OI as well as between adults with OI and the referent PROMIS® population, but the clinical significance of these differences is uncertain. Adults with OI report lower general health status but are otherwise more similar to the general population than might have been expected. While reassuring, further analysis of the extensive OI-ANHI databank should help identify areas of unique clinical concern and for future research. The OI-ANHI survey experience supports an internet-based strategy for successful patient-centered outcomes research in rare disease populations.

Non-communicable Disease (NCD) is increasingly burdening developing countries including Indonesia. However only a few intervention studies on NCD control in developing countries are reported. This study aims to report experiences from the development of a community-based pilot intervention to prevent cardiovascular disease (CVD), as initial part of a future extended PRORIVA program (Program to Reduce Cardiovascular Disease Risk Factors in Yogyakarta, Indonesia) in an urban area within Jogjakarta, Indonesia. The study is quasi-experimental and based on a mixed design involving both quantitative and qualitative methods. Four communities were selected as intervention areas and one community was selected as a referent area. A community-empowerment approach was utilized to motivate community to develop health promotion activities. Data on knowledge and attitudes with regard to CVD risk factors, smoking, physical inactivity, and fruit and vegetable were collected using the WHO STEPwise questionnaire. 980 people in the intervention areas and 151 people in the referent area participated in the pre-test. In the post-test 883 respondents were re-measured from the intervention areas and 144 respondents from the referent area. The qualitative data were collected using written meeting records (80), facilitator reports (5), free-listing (112) and in-depth interviews (4). Those data were analysed to contribute a deeper understanding of how the population perceived the intervention. Frequency and participation rates of activities were higher in the low socioeconomic status (SES) communities than in the high SES communities (40 and 13 activities respectively). The proportion of having high knowledge increased significantly from 56% to 70% among men in the intervention communities. The qualitative study shows that respondents thought PRORIVA improved their awareness of CVD and encouraged them to experiment healthier behaviours. PRORIVA was perceived as a useful program and was expected for the continuation. Citizens of low SES communities thought PRORIVA was a "cheerful" program. A community-empowerment approach can encourage community participation which in turn may improve the citizen's knowledge of the danger impact of CVD. Thus, a bottom-up approach may improve citizens' acceptance of a program, and be a feasible way to prevent and control CVD in urban communities within a low income country.

Chronic kidney disease is classified in stages 1 to 5 by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative depending on the level of renal function by glomerular filtration rate and, more recently, using further categorization depending on the level of glomerular filtration rate and albuminuria by the Kidney Disease Improving Global Outcomes initiative. Registered dietitian nutritionists can be reimbursed for medical nutrition therapy in chronic kidney disease stages 3 to 4 for specific clients under Center for Medicare and Medicaid Services coverage. This predialysis medical nutrition therapy counseling has been shown to both potentially delay progression to stage 5 (renal replacement therapy) and decrease first-year mortality after initiation of hemodialysis. The Joint Standards Task Force of the American Dietetic Association (now the Academy of Nutrition and Dietetics), the Renal Nutrition Dietetic Practice Group, and the National Kidney Foundation Council on Renal Nutrition collaboratively published 2009 Standards of Practice and Standards of Professional Performance for generalist, specialty, and advanced practice registered dietitian nutritionists in nephrology care. The purpose of this article is to provide an update on current recommendations for screening, diagnosis, and treatment of adults with chronic kidney disease for application in clinical practice for the generalist registered dietitian nutritionist using the evidence-based library of the Academy of Nutrition and Dietetics, published clinical practice guidelines (ie, National Kidney Foundation Council on Renal Nutrition, Renal Nutrition Dietetic Practice Group, Kidney Disease Outcomes Quality Initiative, and Kidney Disease Improving Global Outcomes), the Nutrition Care Process model, and peer-reviewed literature.
