    Acute cystitis is one of the most commonly encountered bacterial infections and is responsible for substantial morbidity and high medical costs in the United States and across the globe. Though generally considered to be self-limiting and easily treated with antibiotics, urinary tract infections (UTIs) are often incompletely resolved by antibiotic therapy and frequently recur. This is in part due to the ability of uropathogenic bacteria to invade, replicate, and persist within host epithelial cells. The biological complexity of these infections combined with a dramatic rise in antibiotic-resistant pathogens highlight the need for alternative therapies. In this review we examine current management strategies for UTIs, as well as emerging treatments, including novel compounds that block bacterial interactions with the urothelium and vaccines focused on preventing both acute and recurrent infections.

    Sarcopenia, the loss of skeletal muscle mass and function that occurs with aging, is associated with increased risk for several adverse health outcomes, including frailty, disability, falls, loss of independent living, and mortality. At present, no pharmacological treatment exists that is able to definitely halt the progression of sarcopenia. Likewise, no pharmacological remedies are yet available to prevent the onset of age-related muscle wasting. In this scenario, the combination of nutritional interventions and physical exercise appears to be the most effective strategy presently available for the management of sarcopenia. The purposes of this review are to summarize the current knowledge on the role of nutrition as a countermeasure for sarcopenia, illustrate the mechanisms of action of relevant dietary agents on the aging muscle, and introduce novel nutritional strategies that may help preserve muscle mass and function into old age. Issues related to the identification of the optimal timing of nutritional interventions in the context of primary and secondary prevention are also discussed. Finally, the prospect of elaborating personalized dietary and physical exercise recommendations through the implementation of integrated, high-throughput analytic approaches is illustrated.

    2016-04-01

    Sports-related concussions (SRCs) are traumatic events that affect up to 3.8 million athletes per year. The initial diagnosis and management is often instituted on the field of play by coaches, athletic trainers, and team physicians. SRCs are usually transient episodes of neurological dysfunction following a traumatic impact, with most symptoms resolving in 7-10 days; however, a small percentage of patients will suffer protracted symptoms for years after the event and may develop chronic neurodegenerative disease. Rarely, SRCs are associated with complications, such as skull fractures, epidural or subdural hematomas, and edema requiring neurosurgical evaluation. Current standards of care are based on a paradigm of rest and gradual return to play, with decisions driven by subjective and objective information gleaned from a detailed history and physical examination. Advanced imaging techniques such as functional MRI, and detailed understanding of the complex pathophysiological process underlying SRCs and how they affect the athletes acutely and long-term, may change the way physicians treat athletes who suffer a concussion. It is hoped that these advances will allow a more accurate assessment of when an athlete is truly safe to return to play, decreasing the risk of secondary impact injuries, and provide avenues for therapeutic strategies targeting the complex biochemical cascade that results from a traumatic injury to the brain.

    2014-01-01

    Acute esophageal variceal hemorrhage is one of the clinical events that define decompensated cirrhosis and is associated with high rates of morbidity and mortality. Although recent treatment strategies have led to improved outcomes, variceal hemorrhage still carries a 6-week mortality rate of 15-20%. Current standards in its treatment include antibiotic prophylaxis, infusion of a vasoactive drug and endoscopic variceal ligation. The placement of a transjugular intrahepatic portosystemic shunt (TIPS) is considered for patients that have treatment failure or recurrent bleeding. Recurrent hemorrhage is prevented with the combination of a non-selective beta-blocker and endoscopic variceal ligation. These recommendations however assume that all patients with cirrhosis are equal. Based on a review of recent evidence, a strategy in which patients are stratified by Child class, the main predictor of outcomes, is proposed. PMID:24955303

    Subarachnoid hemorrhage (SAH) from a ruptured intracranial aneurysm represents a major health issue. Although most people who experience an aneurysmal SAH survive to be admitted to a hospital, less than one third of these patients ever return to their premorbid status. Clearly, morbidity of this magnitude demands reevaluation of the clinical approach to this problem. This article reviews the natural history of aneurysmal SAH, and examines the current therapeutic strategies that have been suggested to improve the outcome. Careful evaluation of the existing data suggests that early aneurysm surgery and aggressive postoperative volume expansion therapy constitute the best presently available approach to patients with ruptured intracranial aneurysms.

    This manuscript focuses on high-risk factors of metastatic disease in retinoblastoma and evaluation of the current treatments of retinoblastoma. Presence of histopathologic high-risk factors is associated with a higher risk of local recurrence and systemic metastasis. Currently, globe-sparing therapies, including systemic chemotherapy, intra-arterial chemoreduction, intravitreal chemotherapy, focal consolidation, and combination therapies, are being used and investigated actively. Major advances are being made in the diagnosis and management of retinoblastoma that will lead to improved morbidity and mortality rates in patients with retinoblastoma. By saving the globes, fronting with some high-risk factors for metastasis would be inevitable. International multi-institutional prospective studies could resolve current uncertainties regarding the main tumor treatment regimens for each patient and indications for chemoprophylaxis for high-risk-factor-bearing retinoblastoma cases.

    Muscle injuries frequently occur during sport and are one of the commonest injuries. The diagnosis and treatment of muscle injuries impose high demands on medical treatment, in order to ensure successful regeneration and a rapid return to sport. Most of the injuries can be treated conservatively, as skeletal muscles have a high endogenous capacity for repair and regeneration. Conservative treatment includes initial on-field therapy. This is known as the "RICE" principle and is common and recommended for initial treatment for most sports injuries. The primary therapy target is to reduce pain, swelling and bleeding and thus to limit the initial inflammatory process and prevent further damage. During the first days after injury, brief immobilization helps to reduce the re-injury rate and accelerates the formation of granulation tissue. There are many possible additional treatments, including intramuscular injections, manipulation of the sacroiliac joint or rehabilitation programs, including stretching and strengthening. If the acute treatment phase is complete after 3 to 5 days, more active treatment, including trunk stabilisation, stretching and strengthening, can be started gradually. Despite their high prevalence, there have only been a few studies on the treatment and management of these injuries. The aim of this manuscript is to review the literature on the classification, pathobiology and treatment strategies for muscle injuries. PMID:27351158

    The current trend in treating dental caries is using nondestructive risk-based caries management strategies rather than focusing on the restorative treatment alone. Currently, there have been many changes in understanding of the multifaceted nature of caries process and its management. Caries Management by Risk Assessment (CAMBRA) which is an evidence-based approach focuses on determining many factors causing the expression of disease and take corrective action. The clinicians can ascertain what behaviors are increasing a patient's risk for disease and disease progression by evaluating the current caries risk of a patient. With this modern CAMBRA protocol, a novel treatment plan can be designed to arrest dental caries thereby decreasing the chance of cavitation. After the recognition of the multi factorial nature of caries involving the biofilm, the contemporary approaches focused mainly on the various options to cope with the locally out-of-balance oral biofilm and stop the progression of the disease. The initial caries lesions can be diagnosed with modern diagnostic aids and with the help of CAMBRA, reestablishment of the integrity of the tooth surface early on in the caries process will bring great rewards for patients. This review focuses on the repair of hard tooth tissues using noninvasive strategies. PMID:26538870

    Functional dyspepsia refers to painful and nonpainful symptoms that are perceived to arise in the upper digestive tract but are not secondary to organic, systemic or metabolic diseases. The symptoms of this syndrome often overlap with those of GERD and IBS, making its management far from simple. If Helicobacter pylori infection is diagnosed in patients with functional dyspepsia, it should be treated. In patients with mild or intermittent symptoms, reassurance and lifestyle advice might be sufficient; in patients not responding to these measures, or in those with more severe symptoms, drug therapy should be considered. Both PPIs and prokinetics can be used in initial empirical pharmacotherapy based on symptom patterns--a PPI is more likely to be effective in the presence of retrosternal or epigastric burning or epigastric pain, whereas a prokinetic is more effective in dyspepsia with early satiation or postprandial fullness. Although combinations of PPIs and prokinetics might have additive symptomatic effects, single-drug therapy is initially preferable. Antidepressants or referral to a psychiatrist or psychotherapist can be considered in nonresponders and in those whose symptoms have a marked effect on daily functioning. Despite extensive research, functional dyspepsia treatment often remains unsatisfactory. Better characterization of dyspeptic subgroups and understanding of underlying mechanisms will enable treatment advances to be made in the future. PMID:23381190

    As the effects of climate change becomes more prominent, current challenges related to water and wastewater management is becoming more serious. Providing water that satisfies environmental and safety standards in terms of quantity and quality is needed to maintain human life without compromising the need of future generations. Besides providing safe and affordable water, necessary treatment should be achieved according to several important factors such as receiving body standards, discharge standards, water reuse options. Therefore, management of water becomes more crucial than ever that states have to provide accessibility of safe water with affordable cost to its citizens with the means of effective utility management, including water treatment facilities, wastewater treatment facilities, water supply facilities and water distribution systems. Water utilities encounter with several challenges related to cost, infrastructure, population, legislation, workforce and resource. This study aims to determine the current situation and the necessary strategies to improve utility management in Turkish municipalities in a sustainable manner. US Environment Protection Agency (EPA) has formed a tool on effective utility management that assists utilities to provide a solution for both current and future challenges. In this study, we used EPA's guidelines and developed a survey consists of 60 questions under 10 sub-topics (Product Quality, Employee & Leadership Development, Stakeholder Understanding & Support, Operational Optimization, Infrastructure Stability, Financial Viability, Community Sustainability, Customer Satisfaction, Operational Resiliency, and Water Resource Adequacy). This survey was sent to the managers of 25 metropolitan municipalities in Turkey to assess the current condition of municipalities. After the evaluation of the survey results for each topic, including the importance given by managers, facilities were rated according to their level of achievement

    E-waste is one of the fastest-growing waste streams in Iran, owing to an increase in consumption of electrical and electronic equipment. Nevertheless, as is the case in some other countries, E-waste management has not received sufficient attention. For the successful implementation of any waste management plan (including an E-waste management plan), the availability of sufficient and accurate information on the quantities and composition of the waste generated and on current management conditions is a fundamental prerequisite. At present, in Iran, there is no available and accurate information that describes the characteristics and generation rate of E-waste or the actual practice of management and handling of the waste. For this initial study, eight electronic products were selected for the determination of their E-waste generation rate in the country, and two cities, Tehran and Tabriz, were selected for assessment of the current condition of E-waste management. The study found that the amount of E-waste generation in the country for the eight selected electronic items alone was 115,286, 112,914 and 115,151 metric tons in 2008, 2009 and 2010, respectively. Of the types of electronic items included in the study, televisions, with an average of 42.42%, and PCs, with an average of 32.66% accounted for the greatest proportions of the total mass of E-waste generated during 2008-2010. Currently, despite the fact that primary legislation for E-waste management (as part of general waste legislation) exists in Iran, this primary legislation has not yet been implemented. In practical terms, there is no definite policy or plan for the allocation of funds to prepare suitable equipment and facilities for the management and recycling of E-waste at the end of the products' useful life. Proposed improvements in current conditions are identified, first by considering other countries' experiences and then suggesting specific practical policies, rules, and regulations that should be

    Background Evidence-based medicine is the “conscientious application of scientific best practice by clinicians in concert with patient understanding and values.”[1] Recent studies by the Institute of Medicine, RAND, and others have called attention to the gap between scientifically supported approaches to care and day-to-day practice by clinicians. Compounding the problem of non-adherence by providers, researchers have observed that patient compliance also falls short. As a result, avoidable costs from inappropriate variability in practice patterns coupled with patient noncompliance are a significant focus of managed care. Managed care plans play a key role in the selection of providers by consumers and in the design of benefits programs by employers. Avoidable costs from misuse, overuse, and under-use of care from clinicians is a strategic focus for health plans. The evidence upon which a plan makes coverage decisions and the incorporation of evidence in programs targeting providers, employers, and consumers was a focus of this study. Methodology A Delphi survey and 2-day interactive sessions with 128 clinical program directors and medical officers from 89 health plans were the primary methods used in this descriptive analysis. To test participant applications of evidence-based medicine in health plan medical management strategy, 3 conditions were used for illustrative purpose: managing rheumatoid arthritis, increasing remission in depression, and reducing heart disease among diabetics. Each provided a unique challenge to plans in terms of condition prevalence, strength of evidence, and cost. Key Findings Health plans incorporate evidence-based medicine in 5 areas overseen by medical management: (1) coverage decisions wherein improvements in pharmaceutical and therapeutic review processes are sought, (2) disease management efforts wherein increased attention to secondary prevention is desirable, (3) provider profiling wherein increased use of adherence

    Venous thromboembolism (VTE) is a disease state that carries significant morbidity and mortality, and is a known cause of preventable death in hospitalized and orthopedic surgical patients. There are many identifiable risk factors for VTE, yet up to half of VTE incident cases have no identifiable risk factor and carry a high likelihood of recurrence, which may warrant extended therapy. For many years, parenteral unfractionated heparin, low-molecular weight heparin, fondaparinux, and oral vitamin K antagonists (VKAs) have been the standard of care in VTE management. However, limitations in current drug therapy options have led to suboptimal treatment, so there has been a need for rapid-onset, fixed-dosing novel oral anticoagulants in both VTE treatment and prophylaxis. Oral VKAs have historically been challenging to use in clinical practice, with their narrow therapeutic range, unpredictable dose responsiveness, and many drug–drug and drug–food interactions. As such, there has also been a need for novel anticoagulant therapies with fewer limitations, which has recently been met. Dabigatran etexilate is a fixed-dose oral direct thrombin inhibitor available for use in acute and extended treatment of VTE, as well as prophylaxis in high-risk orthopedic surgical patients. In this review, the risks and overall benefits of dabigatran in VTE management are addressed, with special emphasis on clinical trial data and their application to general clinical practice and special patient populations. Current and emerging therapies in the management of VTE and monitoring of dabigatran anticoagulant-effect reversal are also discussed. PMID:26064057

  16. Mycotoxin problem in Africa: current status, implications to food safety and health and possible management strategies.

    Mycotoxins are toxic secondary metabolites of fungal origin and contaminate agricultural commodities before or under post-harvest conditions. They are mainly produced by fungi in the Aspergillus, Penicillium and Fusarium genera. When ingested, inhaled or absorbed through the skin, mycotoxins will cause lowered performance, sickness or death on humans and animals. Factors that contribute to mycotoxin contamination of food and feed in Africa include environmental, socio-economic and food production. Environmental conditions especially high humidity and temperatures favour fungal proliferation resulting in contamination of food and feed. The socio-economic status of majority of inhabitants of sub-Saharan Africa predisposes them to consumption of mycotoxin contaminated products either directly or at various points in the food chain. The resulting implications include immuno-suppression, impaired growth, various cancers and death depending on the type, period and amount of exposure. A synergistic effect between mycotoxin exposure and some important diseases in the continent such as malaria, kwashiorkor and HIV/AIDS have been suggested. Mycotoxin concerns have grown during the last few decades because of their implications to human and animal health, productivity, economics of their management and trade. This has led to development of maximum tolerated limits for mycotoxins in various countries. Even with the standards in place, the greatest recorded fatal mycotoxin-poisoning outbreak caused by contamination of maize with aflatoxins occurred in Africa in 2004. Pre-harvest practices; time of harvesting; handling of produce during harvesting; moisture levels at harvesting, transportation, marketing and processing; insect damage all contribute to mycotoxin contamination. Possible intervention strategies include good agricultural practices such as early harvesting, proper drying, sanitation, proper storage and insect management among others. Other possible interventions

    2013-01-01

    Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity that manifests as profuse, repetitive vomiting, often with diarrhea, leading to acute dehydration and lethargy or weight loss and failure to thrive if chronic. FPIES is elicited most commonly by milk and soy proteins; however, rice, oat, and other solid foods may also elicit FPIES. Certain FPIES features overlap with food protein-induced enteropathy and proctocolitis, whereas others overlap with anaphylaxis. FPIES is not well recognized among pediatricians and emergency department physicians; the affected children are often mismanaged as having acute viral gastrointestinal illness, sepsis, or surgical disease, delaying diagnosis of FPIES for many months. The aim of this review is to provide case-driven presentation of the features of FPIES. Although randomized clinical trials on management options are missing, the relevant current literature and authors' experience are reviewed in detail. PMID:24565536

    Many advances in genetic selection, nutrition, housing and disease control have been incorporated into modern pork production since the 1950s resulting in highly prolific females and practices and technologies, which significantly increased efficiency of reproduction in the breeding herd. The objective of this manuscript is to review the literature and current industry practices employed for reproductive management. In particular the authors focus on assisted reproduction technologies and their application for enhanced productivity. Modern maternal line genotypes have lower appetites and exceptional lean growth potential compared to females of 20 yr ago. Thus, nutrient requirements and management techniques and technologies, which affect gilt development and sow longevity, require continuous updating. Failure to detect estrus accurately has the greatest impact on farrowing rate and litter size. Yet, even accurate estrus detection will not compensate for the variability in the interval between onset of estrus and actual time of ovulation. However, administration of GnRH analogs in weaned sows and in gilts after withdrawal of altrenogest do overcome this variability and thereby synchronize ovulation, which makes fixed-time AI practical. Seasonal infertility, mediated by temperature and photoperiod, is a persistent problem. Training workers in the art of stockmanship is of increasing importance as consumers become more interested in humane animal care. Altrenogest, is used to synchronize the estrous cycle of gilts, to prolong gestation for 2-3 d to synchronize farrowing and to postpone post-weaning estrus. P.G. 600® is used for induction of estrus in pre-pubertal gilts and as a treatment to overcome seasonal anestrous. Sperm cell numbers/dose of semen is significantly less for post cervical AI than for cervical AI. Real-time ultrasonography is used to determine pregnancy during wk 3-5. PGF2α effectively induces farrowing when administered within two d of normal

    Background: There has been a tremendous amount of interest focused on the topic of concussions over the past few decades. Neurosurgeons are frequently consulted to manage patients with mild traumatic brain injuries (mTBI) that have radiographic evidence of cerebral injury. These injuries share significant overlap with concussions, injuries that typically do not reveal radiographic evidence of structural injury, in the realms of epidemiology, pathophysiology, outcomes, and management. Further, neurosurgeons often manage patients with extracranial injuries that have concomitant concussions. In these cases, neurosurgeons are often the only “concussion experts” that patients encounter. Results: The literature has been reviewed and data have been synthesized on the topic including sections on historical background, epidemiology, pathophysiology, diagnostic advances, clinical sequelae, and treatment suggestions, with neurosurgeons as the intended target audience. Conclusions: Neurosurgeons should have a fundamental knowledge of the scientific evidence that has developed regarding concussions and be prepared to guide patients with treatment plans.

    Cardiovascular disease is the leading cause of death in the United States. In 2010, the Centers for Disease Control and Prevention estimated that $444 billion was spent on cardiovascular diseases alone, about $1 of every $6 spent on health care. As life expectancy continues to increase, this annual cost will also increase, making cost-effective primary prevention of cardiovascular disease highly desirable. Because of its role in development of atherosclerosis and clinical events, dyslipidemia management is a high priority in cardiovascular prevention. Multiple major dyslipidemia guidelines have been published around the world recently, four of them by independent organizations in the United States alone. They share the goal of providing clinical guidance on optimal dyslipidemia management, but guidelines differ in their emphasis on pharmacotherapy, stratification of groups, emphasis on lifestyle modification, and use of a fixed target or percentage reduction in low density lipoprotein cholesterol. This review summarizes eight major guidelines for dyslipidemia management and considers the basis for their recommendations. Our primary aim is to enhance understanding of dyslipidemia management guidelines in patient care for primary prevention of future cardiovascular risk. PMID:26981215

    Penile cancer is an uncommon malignancy that has a devastating effect on the patient while also being challenging to diagnose and treat. By implementing preventive measures, we can decrease the incidence of this disease and improve the quality of life of our patients. Early detection plays an important role in disease control and proper diagnostic modalities must be used in order to accurately identify the cancer and its progression. Primary penile lesions should be initially approached when surgically feasible and clinically appropriate with penile preserving surgical techniques. Advances in inguinal lymph node detection and management, has improved the clinical outcome of penile cancer. Advanced penile cancer still portends a poor prognosis and should be approached via a multimodal treatment regimen. In this review, we address the importance of prevention, early detection, and the contemporary management of primary penile lesions, as well as the advances in inguinal lymph node disease detection and surgical treatment, for both localized and advanced disease.

    2004-12-01

    Childhood papillary thyroid carcinoma is associated with more locally aggressive and more frequent distant disease than its adult counterpart. Recurrence rates tend to be higher in children, but cause-specific mortality remains low. Optimal initial treatment of childhood papillary thyroid carcinoma should include total or near-total thyroidectomy and central compartment node clearance. Modified neck dissections should be performed for biopsy-proven lateral neck disease. Every effort should be made to maintain parathyroid and laryngeal nerve function. Radical neck dissections are to be avoided. Radioiodine remnant ablation (RRA), appropriate thyroid hormone suppressive therapy (THST), and judicious use of therapeutic doses of (131)I are applied to achieve a disease-free status, which is most often confirmed by negative neck ultrasonography, negative whole-body scan (either withdrawal or recombinant human thyroid-stimulating hormone-stimulated), and extremely low levels of serum thyroglobulin. Appropriate utilization of (131)I, THST, repeat surgery, external beam radiotherapy, and rarely chemotherapy may provide long-term palliation and some cures in patients with recurrent/persistent disease. Follow-up should be lifelong, and the care of children after age 17 should subsequently be transferred to adult-care endocrinologists with expertise in managing thyroid neoplasia. Optimal surgical management can be achieved if adequate operations are routinely carried out by "high-volume" thyroid surgeons with expertise in the care of children. Nowhere is a multidisciplinary approach (endocrinologists, surgeons, nuclear medicine physicians, pediatricians, pathologists, oncologists) more critical than in the long-term management of papillary thyroid carcinoma that presents during childhood.

    2010-04-01

    Pressure ulcers (pressure sores) continue to be a common health problem, particularly among the physically limited or bedridden elderly. The problem exists within the entire health framework, including hospitals, clinics, long-term care facilities and private homes. For many elderly patients, pressure ulcers may become chronic for no apparent reason and remain so for prolonged periods, even for the remainder of the patient's lifetime. A large number of grade 3 and 4 pressure ulcers become chronic wounds, and the afflicted patient may even die from an ulcer complication (sepsis or osteomyelitis). The presence of a pressure ulcer constitutes a geriatric syndrome consisting of multifactorial pathological conditions. The accumulated effects of impairment due to immobility, nutritional deficiency and chronic diseases involving multiple systems predispose the aging skin of the elderly person to increasing vulnerability. The assessment and management of a pressure ulcer requires a comprehensive and multidisciplinary approach in order to understand the patient with the ulcer. Factors to consider include the patient's underlying pathologies (such as obstructive lung disease or peripheral vascular disease), severity of his or her primary illness (such as an infection or hip fracture), co-morbidities (such as dementia or diabetes mellitus), functional state (activities of daily living), nutritional status (swallowing difficulties), and degree of social and emotional support; focusing on just the wound itself is not enough. An understanding of the physiological and pathological processes of aging skin throws light on the aetiology and pathogenesis of the development of pressure ulcers in the elderly. Each health discipline (nursing staff, aides, physician, dietitian, occupational and physical therapists, and social worker) has its own role to play in the assessment and management of the patient with a pressure ulcer. The goals of treating a pressure ulcer include avoiding any

    In accordance with international targets, the Uganda National Malaria Control Strategic Plan established specific targets to be achieved by 2010. For children under five, this included increasing the number of children sleeping under mosquito nets and those receiving a first-line antimalarial to 85%, and decreasing case fatality to 2%. This narrative review offers contextual information relevant to malaria management in Uganda since the advent of artemisinin combination therapy (ACT) as first-line antimalarial treatment in 2004. A comprehensive search using key words and phrases was conducted using the web search engines Google and Google Scholar, as well as the databases of PubMed, ERIC, EMBASE, CINAHL, OvidSP (MEDLINE), PSYC Info, Springer Link, Cochrane Central Register of Controlled Trials (CENTRAL), and Cochrane Database of Systematic Reviews were searched. A total of 147 relevant international and Ugandan literature sources meeting the inclusion criteria were included. This review provides an insightful understanding on six topic areas: global and local priorities, malarial pathology, disease burden, malaria control, treatment guidelines for uncomplicated malaria, and role of the health system in accessing antimalarial medicines. Plasmodium falciparum remains the most common cause of malaria in Uganda, with children under five being most vulnerable due to their underdeveloped immunity. While international efforts to scale up malaria control measures have resulted in considerable decline in malaria incidence and mortality in several regions of sub-Saharan Africa, this benefit has yet to be substantiated for Uganda. At the local level, key initiatives have included implementation of a new antimalarial drug policy in 2004 and strengthening of government health systems and programs. Examples of such programs include removal of user fees, training of frontline health workers, providing free ACT from government systems and subsidized ACT from licensed private

    Sleep and circadian disorders in Alzheimer’s disease (AD) are more frequent than in the general population and appear early in the course of the disease. Quality of sleep and quality of life are parallel in these patients, and such disorders also represent a heavy burden for caregivers. Although alterations in melatonin and hypocretins (orexins) seem to play a key role in the origin of these disturbances, the etiology of these disorders is multifactorial, including many factors such as environment, behavior, treatments, and comorbidities, among others. A comprehensive evaluation of sleep in each patient is essential in the design of the treatment that includes nonpharmacological and pharmacological approaches. One particularly interesting point is the possibility of a role of sleep disorders in the pathogenesis of AD, raising the possibility that treating the sleep disorder may alter the course of the disease. In this review, we present an update on the role of sleep disorders in AD, the bidirectional influence of sleep problems and AD, and treatment options. Behavioral measures, bright light therapy (BLT), melatonin, and other drugs are likely well known and correctly managed by the physicians in charge of these patients. In spite of the multiple treatments used, evidence of efficacy is scarce and more randomized double-blind placebo-controlled studies are needed. Future directions for treatment are the establishment of BLT protocols and the development of drugs with new mechanisms of action, especially hypocretin receptor antagonists, melatonin receptor agonists, and molecules that modulate the circadian clock.

    Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

    Partial caries removal procedures are used clinically in an attempt to conserve tooth structure and prevent pulp damage. Within this approach, the caries-infected dentin is removed, and the partially demineralized caries-affected dentin is preserved and sealed with materials that enhance remineralization. Fluoride-releasing glass ionomers have been commonly used for this purpose. Recent studies have shown potential for other cements and bioactive adhesive materials to promote dentin repair through various strategies. These strategies include ion releasing of Ca-P and the guided tissue remineralization or biomimetic remineralization of dentin. The latter is potentially useful in the remineralization of the demineralized acid-etched dentin that is incompletely infiltrated by adhesives in dentin bonding. The purpose of this Critical Appraisal is to provide the clinician with a summary of current literature that clarifies understanding of the process of dentin remineralization and to describe current strategies in this area.

But their significant disadvantage is disposal of spent lamps because of containing a few milligrams of toxic metals, especially mercury and lead. For a successful implementation of any waste management plan, availability of sufficient and accurate information on quantities and compositions of the generated waste and current management conditions is a fundamental prerequisite. In this study, CFLs were selected among 20 different brands in Iran. Content of heavy metals including mercury, lead, nickel, arsenic and chromium was determined by inductive coupled plasma (ICP). Two cities, Tehran and Tabriz, were selected for assessing the current waste management condition of CFLs. The study found that waste generation amount of CFLs in the country was about 159.80, 183.82 and 153.75 million per year in 2010, 2011 and 2012, respectively. Waste generation rate of CFLs in Iran was determined to be 2.05 per person in 2012. The average amount of mercury, lead, nickel, arsenic and chromium was 0.417, 2.33, 0.064, 0.056 and 0.012 mg per lamp, respectively.

    The strategy for the management of children with urinary tract anomalies has changed considerably as a result of the development of ultrasound equipment and techniques that allow for detailed fetal evaluation. Hydronephrosis is the most common urogenital anomaly detected, suggesting that an obstructive process may be potentially present. The goal of postnatal management is to identify and treat those patients whose renal function is at risk, while leaving alone the high percentage of patients who are at no risk of renal damage. This management involves a spectrum of radiological, medical, and surgical interventions for diagnosis, surveillance, and treatment. In this article, we review our current understanding of the natural history of antenatal hydronephrosis and its management. PMID:22836304

    Development of dependable systems relies on the ability of the system to determine and respond to off-nominal system behavior. Specification and development of these fault management capabilities must be done in a structured and principled manner to improve our understanding of these systems, and to make significant gains in dependability (safety, reliability and availability). Prior work has described a fundamental taxonomy and theory of System Health Management (SHM), and of its operational subset, Fault Management (FM). This conceptual foundation provides a basis to develop framework to design and implement FM design strategies that protect mission objectives and account for system design limitations. Selection of an SHM strategy has implications for the functions required to perform the strategy, and it places constraints on the set of possible design solutions. The framework developed in this paper provides a rigorous and principled approach to classifying SHM strategies, as well as methods for determination and implementation of SHM strategies. An illustrative example is used to describe the application of the framework and the resulting benefits to system and FM design and dependability.

    Clinical engineering professionals need to continually review and improve their management strategies in order to keep up with improvements in equipment technology, as well as with increasing expectations of health care organizations. In the last 20 years, management strategies have evolved from the initial obsession with electrical safety to flexible criteria that fit the individual institution's needs. Few hospitals, however, are taking full advantage of the paradigm shift offered by the evolution of joint Commission standards. The focus should be on risks caused by equipment failure, rather than on equipment with highest maintenance demands. Furthermore, it is not enough to consider risks posed by individual pieces of equipment to individual patients. It is critical to anticipate the impact of an equipment failure on larger groups of patients, especially when dealing with one of a kind, sophisticated pieces of equipment that are required to provide timely and accurate diagnoses for immediate therapeutic decisions or surgical interventions. A strategy for incorporating multiple criteria to formulate appropriate management strategies is provided in this article. PMID:16796335

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in Western countries. It affects about 1 billion individuals worldwide. While people with simple steatosis have no higher risk of death than the general population, people with non-alcoholic steatohepatitis are at increased risk of death compared to general population. Current management for NAFLD includes diet and lifestyle changes, management of underlying metabolic risk factors and pharmacological therapies. The objective of therapy is to prevent the complications. The problem with dietary and lifestyle interventions is that they are hard to implement. Compliance is the key. Until now, there is still no approved drug for the treatment of NAFLD. Insulin resistance is the main target of pharmacological therapy, but the question that we ask ourselves as physicians is who should receive medical treatment among NAFLD patients and for how long.

BA must be differentiated from parameningeal infections, including epidural abscess and subdural empyema. The BA is a challenge for the neurosurgeon because it is needed good clinical, pharmacological, and surgical skills for providing good clinical outcomes and prognosis to BA patients. Considered an infrequent brain infection, BA could be a devastator entity that easily left the patient into dead. The aim of this work is to review the current concepts regarding epidemiology, pathophysiology, etiology, clinical presentation, diagnosis, and management of BA. PMID:24174804

    This study involved 320 cancer patients from four Northern European countries. Patients with breakthrough pain were questioned about the characteristics of their pain, the current management of their pain, and the acceptability/utility of alternative routes of administration. The median number of episodes was 3/day. Forty-four percent patients reported incident-type pain, 39% spontaneous-type pain, and 17% a combination of these pains. The median duration was 60 min, and the median time to peak intensity was 15 min. Three percent patients reported "mild" pain, 37% "moderate" pain, and 60% "severe" pain. Ninety percent patients stated that the pain interfered with their daily activities. All patients were using opioids as rescue medication (mainly oral morphine/oxycodone), whilst 28% patients were using non-opioids, and 50% patients were using non-pharmacological interventions. Only 55% patients took rescue medication every time they experienced breakthrough pain. Sixty-five percent patients would definitely consider using an oral transmucosal product; patients from Denmark were less likely to answer positively, and a positive response was associated with previous use of the route for breakthrough pain. Seventy-three percent patients reported regular oral problems. Forty-two percent patients would definitely consider using an intranasal product, with 26% patients stating they would definitely not use such a preparation; patients from Denmark and Sweden were less likely to answer positively, and a positive response was associated with male gender, and previous use of the route. Forty-four percent patients reported regular nasal problems. Sixty percent patients would definitely consider using a subcutaneous product, and 44% patients would definitely consider using an intrapulmonary product. PMID:21251860

    Although Hodgkin lymphoma (HL) is largely curable with first-line therapy, approximately one-third of patients will not have a complete response to frontline treatment or will subsequently relapse. Only 50 % of these patients will be effectively salvaged with conventional therapies. The prognosis is particularly poor for those patients with chemotherapy refractory disease, who are unable to obtain even transient disease control, and for patients who relapse following high dose chemotherapy and autologous stem cell transplant. In this review, we summarize the most recent updates on the management of patients with relapsed HL, the role of novel therapies such as brentuximab vedotin, and an overview of promising new agents currently under investigation. We also discuss the role of consolidation strategies such as high-dose chemotherapy and autologous stem cell transplant, and reduced-intensity allogeneic hematopoietic stem cell transplant, and the need for new strategies in the elderly patient population.

    Diverticulitis is classified as uncomplicated or complicated, i.e., associated with perforation, fistula, or obstruction. CT allows more reliable characterization of an acute attack of diverticulitis. Medical management is reserved for uncomplicated diverticulitis and the initial phase of treatment of diverticulitis associated with abscess formation. Percutaneous abscess drainage is a major advance, which permits one-stage resection in a majority of cases. Diverticulitis associated with free perforation can be selectively managed with resection and primary anastomosis, although a Hartmann resection is likely to be performed. A fistula associated with diverticulitis can usually be managed with a one-stage resection. Obstruction can be managed selectively with resection with on-table bowel preparation, primary anastomosis, and proximal diversion. Laparoscopic techniques permit successful performance of elective resections most of the time. Hand assistance is of particular value when the patient has dense fibrosis. PMID:19062658

    Lupus is a chronic, systemic inflammatory condition in which eicosanoids, cytokines, nitric oxide (NO), a deranged immune system, and genetics play a significant role. Our studies revealed that an imbalance in the pro- and antioxidants and NO and an alteration in the metabolism of essential fatty acids exist in lupus. The current strategy of management includes administration of nonsteroidal anti-inflammatory drugs such as hydroxychloroquine and immunosuppressive drugs such as corticosteroids. Investigational drugs include the following: 1) belimumab, a fully human monoclonal antibody that specifically recognizes and inhibits the biological activity of B-lymphocyte stimulator, also known as B-cell-activation factor of the TNF family; 2) stem cell transplantation; 3) rituximab, a chimeric monoclonal antibody against CD20, which is primarily found on the surface of B-cells and can therefore destroy B-cells; and 4) IL-27, which has potent anti-inflammatory actions. Our studies showed that a regimen of corticosteroids and cyclophosphamide, and methods designed to enhance endothelial NO synthesis and augment antioxidant defenses, led to induction of long-lasting remission of the disease. These results suggest that methods designed to modulate molecular signatures of the disease process and suppress inflammation could be of significant benefit in lupus. Some of these strategies could be vagal nerve stimulation, glucose–insulin infusion, and administration of lipoxins, resolvins, protectins, and nitrolipids by themselves or their stable synthetic analogs that are known to suppress inflammation and help in the resolution and healing of the inflammation-induced damage. These strategies are likely to be useful not only in lupus but also in other conditions, such as rheumatoid arthritis, scleroderma, ischemia-reperfusion injury to the myocardium, ischemic heart disease, and sepsis.

This field of breast surgery allows for complete resection of tumor, preservation of normal parenchyma tissue, and the use of local or regional tissue for immediate breast reconstruction at the time of partial mastectomy. These techniques extend the options for breast conservation surgery, improve aesthetic outcomes, have high patient satisfaction and result in better control of tumor margins. This article will detail the approach to evaluating and treating patients undergoing oncoplastic reconstruction.

    There is a disconnect in most companies between strategy formulation and strategy execution. On average, 95% of a company's employees are unaware of, or do not understand, its strategy. If employees are unaware of the strategy, they surely cannot help the organization implement it effectively. It doesn't have to be like this. For the past 15 years, the authors have studied companies that achieved performance breakthroughs by adopting the Balanced Scorecard and its associated tools to help them better communicate strategy to their employees and to guide and monitor the execution of that strategy. Some companies, of course, have achieved better, longer-lasting improvements than others. The organizations that have managed to sustain their strategic focus have typically established a new corporate-level unit to oversee all activities related to strategy: an office of strategy management (OS M). The OSM, in effect, acts as the CEO's chief of staff. It coordinates an array of tasks: communicating corporate strategy; ensuring that enterprise-level plans are translated into the plans of the various units and departments; executing strategic initiatives to deliver on the grand design; aligning employees' plans for competency development with strategic objectives; and testing and adapting the strategy to stay abreast of the competition. The OSM does not do all the work, but it facilitates the processes so that strategy is executed in an integrated fashion across the enterprise. Although the companies that Kaplan and Norton studied use the Balanced Scorecard as the framework for their strategy management systems, the authors say the lessons of the OSM are applicable even to companies that do not use it.

    Women's strategies for managing urinary incontinence were examined in a grounded-theory study. The women's basic social concern was dealing with incontinence in a manner that enabled them to feel normal. Feeling normal meant being able to do what they wanted to do and needed to do to have a normal life-style as they perceived it. This goal was accomplished by normalizing incontinence and its management. Normalization was achieved by directing its course through self-management, accounting for it in terms of personal history and life experiences, and delaying medical counsel. These strategies are described. The findings provide fresh insights about women's response to incontinence and their practice of self-managing its consequences. PMID:8138472

    Current cancer treatments may create profound iatrogenic outcomes. The adverse effects of these treatments still remain, as the serious problems that practicing physicians have to cope with in clinical practice. Although, non-specific cytotoxic agents constitute an effective treatment modality against cancer cells, they also tend to kill normal, quickly dividing cells. On the other hand, therapies targeting the genome of the tumors are both under investigation, and some others are already streamlined to clinical practice. Several approaches have been investigated in order to find a treatment targeting the cancer cells, while not affecting the normal cells. Suicide gene therapy is a therapeutic strategy, in which cell suicide inducing transgenes are introduced into cancer cells. The two major suicide gene therapeutic strategies currently pursued are: cytosine deaminase/5-fluorocytosine and the herpes simplex virus/ganciclovir. The novel strategies include silencing gene expression, expression of intracellular antibodies blocking cells' vital pathways, and transgenic expression of caspases and DNases. We analyze various elements of cancer cells' suicide inducing strategies including: targets, vectors, and mechanisms. These strategies have been extensively investigated in various types of cancers, while exploring multiple delivery routes including viruses, non-viral vectors, liposomes, nanoparticles, and stem cells. We discuss various stages of streamlining of the suicide gene therapy into clinical oncology as applied to different types of cancer. Moreover, suicide gene therapy is in the center of attention as a strategy preventing cancer from developing in patients participating in the clinical trials of regenerative medicine. In oncology, these clinical trials are aimed at regenerating, with the aid of stem cells, of the patients' organs damaged by pathologic and/or iatrogenic factors. However, the stem cells carry the risk of neoplasmic transformation. We discuss

    2012-01-01

    In an 'obesogenic' environment, getting people to eat appropriate amounts is challenging. Several food-based strategies have the potential to promote satiety and moderate energy intake. Components of foods such as macronutrients and functional ingredients can affect satiety; however, for weight management a more comprehensive approach is needed that emphasizes behavioral strategies to improve the overall diet. Research shows that large portions of energy-dense foods facilitate overconsumption and that reductions in portion size and energy density are associated with reduced energy intake. While this suggests that people should eat smaller portions, recent data show that if people lower the energy density of their diet, they can continue to eat their usual amount of food while limiting calories. Furthermore, serving larger portions of low-energy-dense foods can be used strategically to encourage their consumption and reduce dietary energy density, and this has been shown to be associated with decreased energy intake while maintaining satiety. This new understanding of how portion size can be used positively to manage energy intake has the potential to help people achieve sustainable improvements in their energy intake and bodyweight. Science-based strategies that increase the availability of affordable nutrient-rich, lower energy-dense foods are urgently needed. PMID:23128764

    As remission has now become a realistic therapeutic goal in the clinical management of RA due to the introduction and widespread adoption of biologic agents, there is a greater need for earlier diagnoses and objective methods for evaluating disease activity and response to treatment. In this capacity, advanced imaging strategies are assuming an expansive clinical role, particularly as they take advantage of newer imaging technologies and the shift toward imaging at the molecular level. Molecular imaging utilizes target-specific probes to non-invasively visualize molecular, cellular, and physiological perturbations in response to the underlying pathology. Probes for nuclear and MR imaging have been and are being developed that react with discrete aspects of inflammatory and destructive pathways specific to RA. These probes in addition to new MR sequences and contrast agents have the potential to provide an earlier and more reliable assessment of clinical outcome, disease activity, severity, and location, and therapeutic response. Furthermore, these imaging strategies may enable a more fundamental understanding of critical pathophysiological processes and the advent of new molecular therapies. This review will discuss these advances in both nuclear medicine and MRI strategies for imaging RA with a particular emphasis on molecular imaging. PMID:23133812

    The surgical treatment of urethral stricture diseases is continually evolving. Although various surgical techniques are available for the treatment of anterior urethral stricture, no one technique has been identified as the method of choice. This article provides a brief updated review of the surgical options for the management of different sites and different types of anterior urethral stricture. This review also covers present controversies in urethral reconstruction. Among the various procedures available for treating urethral stricture, one-stage buccal mucosal graft urethroplasty is currently widely used. The choice of technique for urethroplasty for an individual case largely depends on the expertise of the surgeon. Therefore, urologists working in this field should keep themselves updated on the numerous surgical techniques to deal with any condition of the urethra that might surface at the time of surgery.

    Hepatocellular carcinoma (HCC) is a highly lethal and the most common primary liver cancer with increasing worldwide incidence. Pathogenesis of HCC is immune mediated, however, not completely understood. Chronic low-grade inflammation alters both innate and adaptive immune responses. As a result tolerogenic environment is established in damaged organ. Up to date, incomplete understanding of HCC pathogenesis and the extend of biomarker variability among patients represent the major obstacle for early diagnosis and for the choice of effective treatment. Among current treatment options for HCC, thermal ablation strategy, which in addition to cancer eradication provides adjuvant/"danger"signal to the patient's immune cells, has demonstrated its active immunotherapeutic effect. In ongoing phase I/II clinical trials, tumor antigen loaded dendritic cell (DC)-based vaccines as well as tumor-specific cytotoxic T cells are being tested. Genetically redirected T cell therapy and more refined autologous vaccines are still awaiting approaches in HCC. The topic of this review focuses on current and bench-to-bedside immunotherapeutic strategies for HCC and discusses their advantages and limitations in clinic. We also weight up several prospective immunotherapeutic approaches which in theory have the potential for further implication in HCC. Combination of the induction of effective antitumor immunity with the inhibition of the mechanisms of tumor-induced immunosuppression ought to be a key objective in these future developments.

    In vivo molecular imaging has a great potential to impact medicine by detecting diseases in early stages (screening), identifying extent of disease, selecting disease- and patient-specific therapeutic treatment (personalized medicine), applying a directed or targeted therapy, and measuring molecular-specific effects of treatment. Current clinical molecular imaging approaches primarily use PET- or SPECT-based techniques. In ongoing preclinical research novel molecular targets of different diseases are identified and, sophisticated and multifunctional contrast agents for imaging these molecular targets are developed along with new technologies and instrumentation for multimodality molecular imaging. Contrast-enhanced molecular ultrasound with molecularly-targeted contrast microbubbles is explored as a clinically translatable molecular imaging strategy for screening, diagnosing, and monitoring diseases at the molecular level. Optical imaging with fluorescent molecular probes and ultrasound imaging with molecularly-targeted microbubbles are attractive strategies since they provide real-time imaging, are relatively inexpensive, produce images with high spatial resolution, and do not involve exposure to ionizing irradiation. Raman spectroscopy/microscopy has emerged as a molecular optical imaging strategy for ultrasensitive detection of multiple biomolecules/biochemicals with both in vivo and ex vivo versatility. Photoacoustic imaging is a hybrid of optical and ultrasound modalities involving optically-excitable molecularly-targeted contrast agents and quantitative detection of resulting oscillatory contrast agent movement with ultrasound. Current preclinical findings and advances in instrumentation such as endoscopes and microcatheters suggest that these molecular imaging modalities have numerous clinical applications and will be translated into clinical use in the near future.

    In the last decade, numerous studies of immunotherapy for malignant glioma (glioblastoma multiforme) have brought new knowledge and new hope for improving the prognosis of this incurable disease. Some clinical trials have reached Phase III, following positive outcomes in Phase I and II, with respect to safety and immunological end points. Results are encouraging especially when considering the promise of sustained efficacy by inducing antitumor immunological memory. Progress in understanding the mechanisms of tumor-induced immune suppression led to the development of drugs targeting immunosuppressive checkpoints, which are used in active clinical trials for glioblastoma multiforme. Insights related to the heterogeneity of the disease bring new challenges for the management of glioma and underscore a likely cause of therapeutic failure. An emerging therapeutic strategy is represented by a combinatorial, personalized approach, including the standard of care: surgery, radiation, chemotherapy with added active immunotherapy and multiagent targeting of immunosuppressive checkpoints.

    2014-01-01

    The literature on network management is extensive. However, it generally explores network structures, neglecting the impact of management strategies. In this article we assess the effect of management strategies on network outcomes, providing empirical evidence from 119 urban revitalization networks. We go beyond current work by testing a path model for the determinants of network outcomes and considering the interactions between the constructs: management strategies, trust, complexity, and facilitative leadership. Our results suggest that management strategies have a strong effect on network outcomes and that they enhance the level of trust. We also found that facilitative leadership has a positive impact on network management as well as on trust in the network. Our findings also show that complexity has a negative impact on trust. A key finding of our research is that managers may wield more influence on network dynamics than previously theorized. PMID:25520529

    2016-01-01

    Stereotactic body radiotherapy (SBRT) has emerged as the standard treatment for medically inoperable early-staged non-small cell lung cancer (NSCLC). The local control rate after SBRT is over 90%. Some forms of tumour motion management and image-guided radiation delivery techniques are the prerequisites for fulfilment of its goal to deliver a high radiation dose to the tumour target without overdosing surrounding normal tissues. In this review, the current strategies of tumour motion management will be discussed, followed by an overview of various image-guided radiotherapy (RT) systems and devices available for clinical practice. Besides medically inoperable stage I NSCLC, SBRT has also been widely adopted for treatment of oligometastasis involving the lungs. Its possible applications in various other cancer illnesses are under extensive exploration. The progress of SBRT is critically technology-dependent. With advancement of technology, the ideal of personalised, effective and yet safe SBRT is already on the horizon. PMID:27606082

    2010-12-01

    Antiplatelet therapy (aspirin + clopidogrel) is the cornerstone of treatment for patients with acute coronary syndromes and/or undergoing percutaneous coronary interventions (PCI). More than 40 million patients worldwide receive clopidogrel, but about 20% of them are nonresponders or poor responders. Many studies using different techniques, platelet agonists and definitions have shown that patients who are poor responders to clopidogrel have an increased risk of death, reinfarction and stent thrombosis. The mechanisms leading to poor responsiveness are not fully elucidated and are likely multifactorial: genetic factors, accelerated platelet turnover, up-regulation of the P2Y12 pathways, high baseline platelet reactivity, poor compliance, underdosing and drug-drug interactions. The management of these patients is very difficult, but evidence does exist showing that a strategy of higher maintenance dose or switch to different thienopyridines (e.g. ticlopidine or prasugrel) or use of glycoprotein IIb/IIIa inhibitors during PCI may be helpful to overcome poor responsiveness and improve the long-term clinical outcome. This review describes the impact of poor responsiveness to clopidogrel on clinical outcomes, the mechanisms leading to poor effect, and the different assays to assess it. Finally, current and future options for its management are discussed. PMID:21355335

    Objective: To review the management of fecal incontinence, which affects more than 1 in 10 people and can have a substantial negative impact on quality of life. Methods: The medical literature between 1980 and April 2012 was reviewed for the evaluation and management of fecal incontinence. Results: A comprehensive history and physical examination are required to help understand the severity and type of symptoms and the cause of incontinence. Treatment options range from medical therapy and minimally invasive interventions to more invasive procedures with varying degrees of morbidity. The treatment approach must be tailored to each patient. Many patients can have substantial improvement in symptoms with dietary management and biofeedback therapy. For younger patients with large sphincter defects, sphincter repair can be helpful. For patients in whom biofeedback has failed, other options include injectable medications, radiofrequency ablation, or sacral nerve stimulation. Patients with postdefecation fecal incontinence and a rectocele can benefit from rectocele repair. An artificial bowel sphincter is reserved for patients with more severe fecal incontinence. Conclusion: The treatment algorithm for fecal incontinence will continue to evolve as additional data become available on newer technologies. PMID:24355892

    Cystinuria is an inherited disorder of the dibasic amino acid transport system in the proximal tubule and the small intestine. Two responsible genes have been identified, the SLC3A1 on chromosome 2 and the SLC7A9 on chromosome 19. The inability of renal tubules to reabsorb cystine and the relative insolubility of cystine at physiological urine pH lead to stone formation. Cornerstone of the treatment remains stone prevention with hyperhydration, urinary alkalization, and pharmacologic therapy. Repeated stone formation necessitates urologic interventions, which mainly include minimally invasive procedures. The appropriate management of cystinuria is often challenging and requires close follow-up of the patient. PMID:24246330

    Hepatocellular carcinoma (HCC) is the most common primary liver malignancy. Despite efforts for prevention and screening as well as development of new technologies for diagnosis and treatment, the incidence of HCC has doubled, and mortality rates have increased in recent decades. A variety of important risk factors are associated with the development of HCC, with any type of cirrhosis, regardless of etiology, being the major contributor. Hepatitis C virus infection with bridging fibrosis or cirrhosis and hepatitis B virus infection are independent risk factors. The diagnosis of HCC is made without liver biopsy in over 90% of cases. Screening with ultrasound and alpha-fetoprotein (AFP) at 6-month intervals is advised; however, it is not adequate for patients on the orthotopic liver transplantation (OLT) list. Triple-phase computed tomography and/or magnetic resonance imaging are used in combination with the detection of AFP, AFP-L3%, and/or des-gamma-carboxy prothrombin due to their superior sensitivities and specificities. Several treatment modalities are available, but only surgical resection and OLT are curative. OLT is available only for patients who meet or are downstaged into Milan or University of California, San Francisco criteria. Other treatment options include radiofrequency ablation, microwave ablation, percutaneous ethanol injection, transarterial chemoembolization, radioembolization, cryoablation, radiation therapy, stereotactic radiotherapy, systemic chemotherapy, and molecularly targeted therapies. The management of HCC is based on tumor size and location, extrahepatic spread, and underlying liver function. Given the complexity of the disease, patients are often best served in centers with experience in HCC management, where a multi-disciplinary approach can take place. PMID:24829542

    Disease management is a strategy of organizing care and services for a patient population across the continuum. It is characterized by a population database, interdisciplinary and interagency collaboration, and evidence-based clinical information. The effectiveness of a disease management program has been measured by a combination of clinical, financial, and quality of life outcomes. In early 1997, driven by a strategic planning process that established three Centers of Excellence (COE), we implemented disease management as the foundation for a new approach to performance improvement utilizing five key strategies. The five implementation strategies are outlined, in addition to a review of the key elements in outcome achievement. PMID:11761788

    2014-01-01

    Some of the most prevalent and debilitating pain conditions arise from the structures innervated by the trigeminal system (head, face, masticatory musculature, temporomandibular joint and associated structures). Orofacial pain (OFP) can arise from different regions and etiologies. Temporomandibular disorders (TMD) are the most prevalent orofacial pain conditions for which patients seek treatment. Temporomandibular disorders include a number of clinical problems that involve the masticatory musculature, the temporomandibular joint (TMJ) or both. Trigeminal neuropathic pain conditions can arise from injury secondary to dental procedures, infection, neoplasias, or disease or dysfunction of the peripheral and/or central nervous system. Neurovascular disorders, such as primary headaches, can present as chronic orofacial pain, such as in the case of facial migraine, where the pain is localized in the second and third division of the trigeminal nerve. Together, these disorders of the trigeminal system impact the quality of life of the sufferer dramatically. A multidisciplinary pain management approach should be considered for the optimal treatment of orofacial pain disorders including both non-pharmacological and pharmacological modalities.

    The prevalence of health-care associated infections caused by multi-drug resistant organisms has significantly increased over the past decade. Among these organisms, Methicillin-resistant Staphylococcus aureus (MRSA) plays a prominent and increasing role. Because of consequences for patients and the economic burden in course of prolonged treatment following MRSA infections and additional indirect costs for e.g. isolation or antiseptic treatment, this trend will further damage European health-care systems. In 2006, a workshop was initiated at the 8th International Congress of the German Society of Hospital Hygiene held in Berlin. The aim of this workshop was to give an overview of the current situation of MRSA in selected European countries and to elaborate on potential strategies to prevent MRSA-infections and dissemination. A questionnaire encompassing 20 questions addressed topics such as epidemiology, current measures and future prospects was distributed to representatives from various European countries and Japan. A variety of widely different answers was obtained. It was shown that in all countries prevalence of MRSA is on a rising tide. This trend is observable in all European countries, albeit less strong in The Netherlands, Slovenia, France, Austria and Scandinavian countries. It was conclude that prevention strategies in a united and expanding European Community will become of utmost importance and that rapid screening strategies, e.g. PCR, might be of assistance in such an approach. A potential strategy to improve infection control measures could be the requirement of health-insurance providers to sign contracts only with hospitals able to proof having an infection control management in place.

    Researchers function in a complex environment and carry multiple role responsibilities. This environment is prone to various distractions that can derail productivity and decrease efficiency. Effective time management allows researchers to maintain focus on their work, contributing to research productivity. Thus, improving time management skills is essential to developing and sustaining a successful program of research. This article presents time management strategies addressing behaviors surrounding time assessment, planning, and monitoring. Herein, the Western Journal of Nursing Research editorial board recommends strategies to enhance time management, including setting realistic goals, prioritizing, and optimizing planning. Involving a team, problem-solving barriers, and early management of potential distractions can facilitate maintaining focus on a research program. Continually evaluating the effectiveness of time management strategies allows researchers to identify areas of improvement and recognize progress. PMID:22868990

    2015-08-01

    Vitiligo is a common inflammatory disorder with worldwide prevalence of 0.4-2 % of the population, with half of cases beginning in childhood. The management of childhood vitiligo should be tailored to avoid negative effects on the overall growth and psychological development of the patient. Therapy of vitiligo in childhood is chosen based on the location of the lesions, lesion age, and extent of lesions in the context of the child's age and the developmental status of the child. There are four age categories in childhood vitiligo: [1] infantile and toddler (rare) (ages 0-3 years), [2] ages 4-8 years, [3] ages 9-12 years, and [4] 13+ years of age, based on developmental stage, psychological maturation, and ability to comply or participate in therapy. These categories are also differentiated psychologically by susceptibility to bullying, self-image development, and personal concern with lesion appearance, which increases with time. Intervention is advisable in cases with facial and leg involvement due to prominence of lesions and cosmetic defect. Medical interventions are largely the usage of topical therapies including corticosteroids and calcineurin inhibitors, some vitamin therapy (oral and topical vitamin D), and judicious introduction of phototherapy sources based on age and severity. Screening and appropriate subspecialist referral for co-morbidities (e.g., thyroid disease, celiac disease, psychological distress, and vitamin D deficiency) may enhance overall health. Cosmesis and camouflage are generally safe in childhood and have been noted to improve overall quality of life in this grouping. Genetic transmission of vitiligo is minimal at 5-6 % in first-degree relatives. This article reviews the therapeutics of pediatric vitiligo from the perspective of developmental stages and response to therapy. PMID:26022363

    Objective: To systematically identify the various methods of speed management and their effects. Methods: A systematic search was performed in Science Direct, Ovid Medline, Scopus, PubMed and ProQuest databases from April to June 2015. Hand searching and reference of selected articles were used to improve article identification. Articles published after 1990 which had reported on efficacy/effectiveness of speed management strategies were included. Data were extracted using pre-defined extraction table. Results: Of the 803 retrieved articles, 22 articles were included in this review. Most of the included articles (63%) had before-after design and were done in European countries. Speed cameras, engineering schemes, intelligent speed adaption (ISA), speed limits and zones, vehicle activated sign and integrated strategies were the most common strategies reported in the literature. Various strategies had different effects on mean speed of the vehicles ranging from 1.6 to 10 km/h. Moreover, 8-65% and 11-71% reduction was reported in person injured accidents and fatal accidents, respectively as a result of employing various strategies. Conclusion: Literature revealed positive effects of various speed management strategies. Using various strategies was mostly dependent on road characteristics, driver’s attitude about the strategy as well as economic and technological capabilities of the country. Political support is considered as a main determinant in selecting speed management strategies. PMID:27540546

    PubMed

    Hansen, M T; Nohria, N; Tierney, T

    1999-01-01

    The rise of the computer and the increasing importance of intellectual assets have compelled executives to examine the knowledge underlying their businesses and how it is used. Because knowledge management as a conscious practice is so young, however, executives have lacked models to use as guides. To help fill that gap, the authors recently studied knowledge management practices at management consulting firms, health care providers, and computer manufacturers. They found two very different knowledge management strategies in place. In companies that sell relatively standardized products that fill common needs, knowledge is carefully codified and stored in databases, where it can be accessed and used--over and over again--by anyone in the organization. The authors call this the codification strategy. In companies that provide highly customized solutions to unique problems, knowledge is shared mainly through person-to-person contacts; the chief purpose of computers is to help people communicate. They call this the personalization strategy. A company's choice of knowledge management strategy is not arbitrary--it must be driven by the company's competitive strategy. Emphasizing the wrong approach or trying to pursue both can quickly undermine a business. The authors warn that knowledge management should not be isolated in a functional department like HR or IT. They emphasize that the benefits are greatest--to both the company and its customers--when a CEO and other general managers actively choose one of the approaches as a primary strategy. PMID:10387767

    2015-08-01

    In this article, we provide a review of the literature on self-management interventions and we are giving some thought to how, when, and by whom they should be offered to patients. The present literature based on randomized clinical trials has demonstrated benefits (reduced hospital admissions and improved health status) for chronic obstructive pulmonary disease (COPD) patients undergoing self-management interventions, although there are still problems with the heterogeneity among interventions, study populations, follow-up time, and outcome measures that make generalization difficult in real life. Key to the success, self-management intervention has to target behavior change. Proper self-management support is a basic prerequisite, for example, techniques and skills used by health care providers "case manager" to instrument patients with the knowledge, confidence, and skills required to effectively self-manage their disease. To improve health behaviors and engagement in self-management, self-management interventions need to target enhancing intrinsic motivation to change. This will best be done using client-centered communication (motivational communication) that encourages patients to express what intrinsically motivates them (e.g., consistent with their values or life goals) to adopt certain health behavior, with the goal of helping them overcome their ambivalence about change. Finally, if we want to be able to design and implement self-management interventions that are integrated, coherent, and have a strong likelihood of success, we need to take a more careful look and give more attention at the case manager, the patient (patient evaluation), and the quality assurance.

    Alopecia areata (AA) is a non-scarring autoimmune disease of the hair follicle that can present at any age. Pediatric cases are commonly seen in a dermatology clinic, and management can potentially be challenging, with a small proportion of cases experiencing a chronic relapsing course marked by distressing hair loss that can bring about significant psychosocial morbidity. We review the established treatments for pediatric alopecia areata, alongside second and third line therapies that have shown to be efficacious. We also offer a treatment algorithm as a guide to the treatment of pediatric AA. PMID:23248364

    Clinical issues related to treating the oncology pain patient have gained considerable attention in the medical and health care literature. Addressed are management strategies which focus specifically on cognitive-behavioral, psychosocial, and pharmacologic approaches to treating the oncology pain patient. Each strategy possesses unique qualities that can benefit the care and management of the cancer patient and provide a better understanding of the disease entity and the patient's ability to develop coping strategies that may be effective in understanding and confronting pain associated with cancer.

    In a time of increased patient loads and emergency department (ED) exit block, the need for strategies to manage patient flow in the ED has become increasingly important. In March 2002 we contacted all 1282 members of the Canadian Association of Emergency Physicians and asked them to delineate strategies for enhancing ED patient flow and ED productivity without increasing stress levels, reducing care standards or compromising patient safety. Thirty physicians responded. Their suggested flow management strategies, which ranged from clinical decision-making to communication to choreography of time, space and personnel, are summarized here.

    PubMed

    Borgne, Anne; Aubin, Henri-Jean; Berlin, Ivan

    2004-11-15

    Smoking is a behaviour maintained and enhanced by a dependence mainly induced by nicotine. Despite awareness and knowledge of the associated health risks many smokers find it considerably difficult to quit. The untoward effects of nicotine withdrawal such as apparition of depressive mood, or weight gain, etc. justify the numerous unsuccessful attempts to quit smoking. Treatments with demonstrated efficacy are available and international evidence-based recommendations for cessation interventions have been established. These are: brief advice, assessing the smoking status of each patient and encouraging cessation; nicotine replacement therapies (NRT) [transdermal patch, gum, sublingual tablet or inhalator to be used at sufficiently individualised doses combining, if necessary, two or more NRT products]; bupropion, a more recent treatment: psychotropic drug, a noradrenaline and dopamine re-uptake inhibitor more recently approved for marketing; behavioural and cognitive therapies on their own or combined with pharmacotherapy. Measuring nicotine dependence using the Fagerström Test for Nicotine Dependence may help to define the therapeutic strategy. It is obvious that therapies can only work for smokers who are motivated to stop smoking. Before reaching the decision to quit, the smoker goes through a process in the course of which the role of health professionals' advice is paramount. PMID:15655912

    1998-01-01

    This report is a joint effort of the Biological Resources Division, U.S. Geological Survey and the U.S. Fish and Wildlife Service (FWS) to provide National Wildlife Refuge (NWR) managers guidance on the selection and evaluation of habitat management strategies to meet stated objectives. The FWS recently completed a handbook on writing refuge management goals and objectives (U.S. Fish and Wildlife Service 1996a). the National Wildlife Refuge System Improvement Act of 1997 requires that National Wildlife Refuge System (NWRS) lands be managed according to approved Comprehensive Conservation Plans to guide management decisions and devise strategies for achieving refuge unit purposes and meeting the NWRS mission. It is expected that over the next several years most refuges will develop new or revised refuge goals and objectives for directing their habitat management strategies. This paper outlines the steps we recommend in selecting and evaluating habitat management strategies to meet specific refuge habitat objectives. We selected two examples to illustrate the process. Although each refuge is unique and will require specific information and solutions, these two examples can be used as guidance when selecting and evaluating habitat management strategies for other refuge resources: Example 1. Management of floodplain woods habitat for forest interior birds. The biological recourse of concern is the quality and quantity of floodplain woods habitat for eastern forest interior birds in the Cypress Creek NWR (U.S. Fish and Wildlife Service 1996b). Example 2. Management of habitat for biodiversity: Historical landscape proportions. The biological resource of concern is the change in diversity associated with man-induced changes in the distribution and abundance of habitat types at the Minnesota Valley NWR (U.S. Fish and Wildlife Service 1996c).

    2016-08-01

    Malignant pleural mesothelioma (MPM) is associated with a poor prognosis. The main components of multimodality treatment include surgery, chemotherapy, and radiation therapy. Surgery remains controversial. Two procedures are currently offered: extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D). The recent scientific literature suggests that P/D is a well-tolerated procedure, with the potential of becoming a default procedure in multimodality regimens. However, the precise treatment schemes and surgical procedures are yet to be established. In our study, we review the advantages and disadvantages of EPP and P/D, summarize the post-EPP and post-P/D observations (including mortality, morbidity, and median survival time), and discuss the choice of surgical technique (EPP vs. P/D). Moreover, we highlight the aspects of the multimodality treatments that are offered to MPM patients, including chemotherapy, radiotherapy, intensity-modulated radiation therapy, and other types of therapy.

    Osteoporosis is a major cause of morbidity in post-menopausal women. Strategies to prevent or delay bone loss in normal post-menopausal women and to reduce the risk of fractures in women with osteoporosis are within the scope of family practice. Certain factors, such as inadequate calcium intake, estrogen deficiency, cigarette smoking and lack of physical activity can be modified in peri- and post-menopausal women. For patients with osteoporosis, there is potential for lowering the risk of fractures by means of calcium supplements or other therapies, physical training and rehabilitation, and modification of factors associated with risk of falling.

    This Heat Management Trade Study was performed in 2008-2009 to expand on prior studies in continued efforts to analyze and evaluate options for cost-effectively managing SNF reprocessing wastes. The primary objective was to develop a simplified cost/benefit evaluation for spent nuclear fuel (SNF) reprocessing that combines the characteristics of the waste generated through reprocessing with the impacts of the waste on heating the repository. Under consideration were age of the SNF prior to reprocessing, plutonium and minor actinide (MA) separation from the spent fuel for recycle, fuel value of the recycled Pu and MA, age of the remaining spent fuel waste prior to emplacement in the repository, length of time that active ventilation is employed in the repository, and elemental concentration and heat limits for acceptable glass waste form durability. A secondary objective was to identify and qualitatively analyze remaining issues such as (a) impacts of aging SNF prior to reprocessing on the fuel value of the recovered fissile materials, and (b) impact of reprocessing on the dose risk as developed in the Yucca Mountain Total System Performance Assessment (TSPA). Results of this study can be used to evaluate different options for managing decay heat in waste streams from spent nuclear fuel.

    2011-04-01

    Novel therapies resulting from regenerative medicine and tissue engineering technology may offer new hope for patients with injuries, end-stage organ failure, or other clinical issues. Currently, patients with diseased and injured organs are often treated with transplanted organs. However, there is a shortage of donor organs that is worsening yearly as the population ages and as the number of new cases of organ failure increases. Scientists in the field of regenerative medicine and tissue engineering are now applying the principles of cell transplantation, material science, and bioengineering to construct biological substitutes that can restore and maintain normal function in diseased and injured tissues. In addition, the stem cell field is a rapidly advancing part of regenerative medicine, and new discoveries in this field create new options for this type of therapy. For example, new types of stem cells, such as amniotic fluid and placental stem cells that can circumvent the ethical issues associated with embryonic stem cells, have been discovered. The process of therapeutic cloning and the creation of induced pluripotent cells provide still other potential sources of stem cells for cell-based tissue engineering applications. Although stem cells are still in the research phase, some therapies arising from tissue engineering endeavors that make use of autologous, adult cells have already entered the clinical setting, indicating that regenerative medicine holds much promise for the future.

    2015-04-01

    Cardiac myxoma is the most common cardiac neoplasm. In the majority of cases, it is isolated (non-syndromic) and located in the left atrium. In up to 10% cases, it is seen in syndromic association with the Carney complex where it is encountered in younger patients, with atypical and multiple locations, such as the right atrium or ventricles, and carries a high risk of recurrence. Imaging is pivotal in the diagnosis, management guidance and surveillance. Surgical excision is the established definitive treatment. Further research should address management strategies in incidentally discovered small myxomas in asymptomatic patients and the role of genetic testing and screening in syndromic myxomas.

    2008-09-01

    Ductal carcinoma in-situ (DCIS) is a heterogeneous disease, in terms of its radiological characteristics, histological morphology and molecular attributes. This diversity is reflected in its natural history and influences optimal treatment strategy. A significant proportion of DCIS lesions behave in a clinically benign fashion and do not progress to invasive disease. Reliable identification of these patients could allow treatment to be less radical or safely omitted. Management should be tailored to the individual within the context of a multidisciplinary team. Approaches such as biological profiling and molecular analysis represent an opportunity to improve our understanding of the tumour biology of this condition and rationalise its treatment. This article reviews the management strategies for DCIS in the context of recent randomized trials, including the role of sentinel lymph node biopsy, adjuvant radiotherapy and tamoxifen.

    Brain metastases management has evolved over the last fifteen years and may use varying strategies, including more or less aggressive treatments, sometimes combined, leading to an improvement in patient's survival and quality of life. The therapeutic decision is subject to a multidisciplinary analysis, taking into account established prognostic factors including patient's general condition, extracerebral disease status and clinical and radiological presentation of lesions. In this article, we propose a management strategy based on the state of current knowledge and available therapeutic resources. PMID:25649388

    SUMMARY Follicular lymphoma (FL) can vary markedly in its initial presentation, and no single standard approach for its initial management has been adopted. Available options for the initial management of FL include watchful waiting, radiation, single-agent rituximab and combination of rituximab and chemotherapy with strategies segregated for patients who have low and high tumor burden disease based on established criteria. However, marked debate occurs regarding the role of watchful waiting in the modern era for low tumor burden, asymptomatic patients, the optimal timing of rituximab, the selection of chemotherapy regimen to partner with rituximab in high tumor burden patients, and strategies for the management of relapsed disease. We provide an evidence-based discussion on these and other issues regarding the management of FL, and propose a mathematical modeling approach for addressing some of these questions. PMID:23476737

    PubMed

    Guerina, N G

    1994-08-01

    This review presented the clinical manifestations, diagnostic and therapeutic options, and preventive strategies for several congenital infections. The infections discussed show the spectrum of modes of vertical transmission and severity of fetal disease encountered, in addition to the successes and limitations of the current medical interventions. Further improvements in diagnostic techniques and therapies for managing the infected fetus are likely to occur during the next decade. Similarly, the widespread adaptation of new and sensitive diagnostic assays, such as the polymerase chain reaction, is likely to further improve our ability to identify infectious agents as the primary cause of certain abnormal fetal conditions. Where specific diagnostic tests and therapies have proven successful in preventing or treating fetal infections, universal screening programs should be given serious consideration. Of paramount importance, however, is the active research on the development of preventive interventions designed to prevent maternal infections and vertical transmission. Although specific immunotherapies, vaccines, and drug therapies hold great promise for controlling the spread of some infections, it cannot be overemphasized that some serious infectious complications of pregnancy may be avoided by simple preconception or early antenatal maternal counseling.

  1. Strategies for Managing a Multigenerational Workforce

    Iden, Ronald

    The multigenerational workforce presents a critical challenge for business managers, and each generation has different expectations. A human resource management study of organizations with more than 500 employees reported 58% of the managers experiencing conflict between younger and older workers. The purpose of this single case study was to explore the multigenerational strategies used by 3 managers from a Franklin County, Ohio manufacturing facility with a population size of 6 participants. The conceptual framework for this study was built upon generational theory and cohort group theory. The data were collected through face-to-face semistructured interviews, company documents, and a reflexive journal. Member checking was completed to strengthen the credibility and trustworthiness of the interpretation of participants' responses. A modified van Kaam method enabled separation of themes following the coding of data. Four themes emerged from the data: (a) required multigenerational managerial skills, (b) generational cohort differences, (c) most effective multigenerational management strategies, and (d) least effective multigenerational management strategies. Findings from this study may contribute to social change through better understanding, acceptance, and appreciation of the primary generations in the workforce, and, in turn, improve community relationships.

  2. Evolutionary space station fluids management strategies

    NASA Technical Reports Server (NTRS)

    1989-01-01

    Results are summarized for an 11-month study to define fluid storage and handling strategies and requirements for various specific mission case studies and their associated design impacts on the Space Station. There are a variety of fluid users which require a variety of fluids and use rates. Also, the cryogenic propellants required for NASA's STV, Planetary, and Code Z missions are enormous. The storage methods must accommodate fluids ranging from a high pressure gas or supercritical state fluid to a sub-cooled liquid (and superfluid helium). These requirements begin in the year 1994, reach a maximum of nearly 1800 metric tons in the year 2004, and trail off to the year 2018, as currently planned. It is conceivable that the cryogenic propellant needs for the STV and/or Lunar mission models will be met by LTCSF LH2/LO2 tanksets attached to the SS truss structure. Concepts and corresponding transfer and delivery operations have been presented for STV propellant provisioning from the SS. A growth orbit maneuvering vehicle (OMV) and associated servicing capability will be required to move tanksets from delivery launch vehicles to the SS or co-orbiting platforms. Also, appropriate changes to the software used for OMV operation are necessary to allow for the combined operation of the growth OMV. To support fluid management activities at the Space Station for the experimental payloads and propellant provisioning, there must be truss structure space allocated for fluid carriers and propellant tanksets, and substantial beam strengthening may be required. The Station must have two Mobile Remote Manipulator Systems (MRMS) and the growth OMV propellant handling operations for the STV at the SS. Propellant needs for the Planetary Initiatives and Code Z mission models will most likely be provided by co-orbiting propellant platform(s). Space Station impacts for Code Z mission fluid management activities will be minimal.

    Slipped capital femoral epiphysis (SCFE) is a common hip condition that can be disabling. In this review, we provide an orientation on current trends in the clinical management of SCFE including conventional procedures and specialised surgical developments. Different methods of fixation of the epiphysis, risks of complications, and the rationale of addressing deformity, primarily or secondarily, are presented. Although improved understanding of the anatomy, vascularity and implications of residual deformity have changed management strategies, the best modality of treatment that would restore complete vascularity to the femoral head and prevent any residual deformity, impingement and early osteoarthritis remains elusive.

    2011-01-01

    This paper reviews the current management of onchocerciasis and its future prospects. Onchocerciasis is a disease affecting millions of people in Africa, South and Central America, and Yemen. It is spread by the blackfly as a vector and caused by the filarial nematode, Onchocerca volvulus. A serious attempt was made by the Onchocerciasis Control Program between 1975 and 2002 to eliminate the vector in eleven of the endemic countries in West Africa, and with remarkable success. Formerly, the treatment was with diethyl carbamazine for the microfilaria and suramin for the adult worm. These drugs are now known to be toxic and unsuitable for mass distribution. In particular, they precipitate optic nerve disease. With the discovery of ivermectin, a much safer microfilaricide, and the decision of Merck to distribute the drug free of charge for as long as needed, the strategy of control switched to mass drug administration through community-directed treatment with ivermectin. So far, millions have received this annual or biannual treatment through the African Program for Onchocerciasis Control and the Onchocerciasis Elimination Program for the Americas. However, the problem with ivermectin is that it is a monotherapy microfilaricide which has limited effect on the adult worm, and thus will need to be continued for the life span of the adult worm, which may last up to 15 years. There are also early reports of resistance. Serious encephalopathy and death may occur when ivermectin is used in subjects heavily infested with loiasis. It seems unlikely that a break in transmission will occur with community-directed treatment with ivermectin in Africa because of population migrations and the highly efficient vector, but in the Americas some countries such as Columbia and the Oaxaca focus in Mexico have reported eradication. Vector control is only now applicable in selected situations, and particularly to control the nuisance value of the blackfly. Trials are ongoing for

    2015-01-01

    Overwork, at first glance, seems like a problem that affects only the employee. But for medical practices and those who manage them, the problem is far greater than that. Chronically overworked employees may not be meeting their goals. They may be making more mistakes and letting things slip through the cracks. Ultimately, patients may have less-than-ideal experiences in a practice where the employees are stretched thin. And turnover may skyrocket in practices where employees are chronically overworked. This article offers practice managers 20 practical and affordable strategies they can use to manage a chronically overworked medical practice team. It suggests an effective technique they can use to tell their bosses that their employees are overworked. This article also suggests the costs to the practice of a chronically overworked staff, including a hidden cost many people overlook. It provides four coping strategies practice managers can teach to their overworked employees. It summarizes research exploring how overwork affects employees' sleep and eating habits, and additional research linking long hours of overwork to diminished productivity. Finally, this article provides five strategies practice managers can use to make their overworked employees feel valued. PMID:26182704

    Incorporating the perspectives and insights of stakeholders is an essential component of ecosystem-based fisheries management, such that policy strategies should account for the diverse interests of various groups of anglers to enhance their efficacy. Here we assessed fishing stakeholders' perceptions on the management of Atlantic striped bass (Morone saxatilis) and receptiveness to potential future regulations using an online survey of recreational and commercial fishers in Massachusetts and Connecticut (USA). Our results indicate that most fishers harbored adequate to positive perceptions of current striped bass management policies when asked to grade their state's management regime. Yet, subtle differences in perceptions existed between recreational and commercial fishers, as well as across individuals with differing levels of fishing experience, resource dependency, and tournament participation. Recreational fishers in both states were generally supportive or neutral towards potential management actions including slot limits (71%) and mandated circle hooks to reduce mortality of released fish (74%), but less supportive of reduced recreational bag limits (51%). Although commercial anglers were typically less supportive of management changes than their recreational counterparts, the majority were still supportive of slot limits (54%) and mandated use of circle hooks (56%). Our study suggests that both recreational and commercial fishers are generally supportive of additional management strategies aimed at sustaining healthy striped bass populations and agree on a variety of strategies. However, both stakeholder groups were less supportive of harvest reductions, which is the most direct measure of reducing mortality available to fisheries managers. By revealing factors that influence stakeholders' support or willingness to comply with management strategies, studies such as ours can help managers identify potential stakeholder support for or conflicts that may

By revealing factors that influence stakeholders’ support or willingness to comply with management strategies, studies such as ours can help managers identify potential stakeholder support for or conflicts that

    Coarctation of the aorta (C) is the sixth most common lesion in congenital heart disease and represents a spectrum of aortic narrowing that varies from a discrete entity to tubular hypoplasia. This condition was once thought to be a relatively simple lesion that would be “cured” upon repair of the narrowing, however, despite relief of the anatomical obstruction the subsequent risk of early morbidity and death persists. This review outlines the optimal management strategy of this disease from neonatal to adult life and provides insights to approach this straightforward but challenging condition. PMID:26779519

    Due to the high incidence of breast cancer in the United States, optimal strategies for its prevention are imperative. This entails identification of women who are at an increased risk for breast cancer and an integrative approach that includes effective screening methods as well as nutritional, pharmacologic, and surgical management. Several breast cancer risk-assessment tools, such as the Gail and Claus models, can help clinicians determine the quantitative risk of breast cancer. The role of selective estrogen receptor modulators, such as tamoxifen and raloxifene, for the prevention of breast cancer has been well established. Several other agents, such as aromatase inhibitors, are currently being investigated. The potential adverse effects of these chemopreventive agents, which include an impact on the quality of life, must be discussed with the patient before deciding on this approach. Additionally, breast cancer risk factors have been identified over the years; some of them are modifiable, but others are not. Although there is no conclusive evidence to suggest the protective role of specific dietary components, alcohol consumption and obesity are associated with an increased breast cancer risk; thus lifestyle changes can lead to a lower risk of developing breast cancer. Surgical approaches, including bilateral risk-reduction mastectomy and salpingo-oophorectomy, are usually limited to women with a hereditary predisposition to development of breast cancer. The objective of this review is to summarize the various approaches directed at reducing the incidence of breast cancer. PMID:24833917

    China faces great challenges in protecting its soil from contamination caused by rapid industrialization and urbanization over the last three decades. Recent nationwide surveys show that 16% of the soil samples, 19% for the agricultural soils, are contaminated based on China’s soil environmental quality limits, mainly with heavy metals and metalloids. Comparisons with other regions of the world show that the current status of soil contamination, based on the total contaminant concentrations, is not worse in China. However, the concentrations of some heavy metals in Chinese soils appear to be increasing at much greater rates. Exceedance of the contaminant limits in food crops is widespread in some areas, especially southern China, due to elevated inputs of contaminants, acidic nature of the soil and crop species or cultivars prone to heavy metal accumulation. Minimizing the transfer of contaminants from soil to the food chain is a top priority. A number of options are proposed, including identification of the sources of contaminants to agricultural systems, minimization of contaminant inputs, reduction of heavy metal phytoavailability in soil with liming or other immobilizing materials, selection and breeding of low accumulating crop cultivars, adoption of appropriate water and fertilizer management, bioremediation, and change of land use to grow nonfood crops. Implementation of these strategies requires not only technological advances, but also social-economic evaluation and effective enforcement of environmental protection law. PMID:25514502

    Over the last 2 decades there has been a tremendous evolution in the evaluation and care of patients with pulmonary arterial hypertension (PAH). The introduction of targeted PAH therapy consisting of prostacyclin and its analogues, endothelin antagonists, phosphodiestase-5 inhibitors, and now a soluble guanylate cyclase activator have increased therapeutic options and potentially reduced morbidity and mortality, yet none of the current therapies have been curative. Current clinical management of PAH has become more complex given the focus on early diagnosis, an increased number of available therapeutics within each mechanistic class, as well as the emergence of clinically challenging scenarios such as perioperative care. Efforts to standardize the clinical care of PAH patients have led to the formation of multidisciplinary PAH tertiary care programs that strive to offer medical care based on peer-reviewed evidence-based and expert consensus guidelines. Furthermore, these tertiary PAH centers often support clinical and basic science research programs to gain novel insights into the pathogenesis of PAH with the goal to improve the clinical management of this devastating disease. In this manuscript, we discuss the clinical approach and management of PAH from the perspective of a single US-based academic institution. We provide an overview of currently available clinical guidelines, and offer some insight into how we approach current controversies in clinical management of certain patient subsets. We conclude with an overview of our program structure as well as a perspective on research and the role of a tertiary PAH center in contributing new knowledge to the field. PMID:24951763

    We develop an analytical approach for more systematically analyzing environmental management problems in order to develop strategic plans. This approach can be deployed by agencies, non-profit organizations, corporations, or other organizations and institutions tasked with improving environmental quality. The analysis relies on assessing the underlying natural processes followed by articulation of the relevant societal forces causing environmental change: (1) science and technology, (2) governance, (3) markets and the economy, and (4) public behavior. The four forces analysis is then used to strategize which types of actions might be most effective at influencing environmental quality. Such strategy has been under-used and under-valued in environmental management outside of the corporate sector, and we suggest that this four forces analysis is a useful analytic to begin developing such strategy.

    Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extraction allows for beneficial use of the excess landfill heat as an alternative energy source. Two approaches are provided for the extraction strategy: extracting all of the excess heat above baseline equilibrium conditions in a landfill and extracting only a part of the excess heat above equilibrium conditions to obtain target optimum waste temperatures for maximum gas generation. Heat regulation allows for controlling the waste temperatures to achieve uniform distribution at target levels at a landfill facility. Two approaches are provided for the regulation strategy: redistributing the excess heat across a landfill to obtain uniform target optimum waste temperatures for maximum gas generation and redistributing the excess heat across a landfill to obtain specific target temperatures. Heat supplementation allows for controlling heat generation using external thermal energy sources to achieve target waste temperatures. Two approaches are provided for the supplementation strategy: adding heat to the waste mass using an external energy source to increase waste temperatures and cooling the waste mass using an external energy source to decrease waste temperatures. For all strategies, available landfill heat energy is determined based on the difference between the waste temperatures and the target temperatures. Example analyses using data from landfill facilities with relatively low and high heat generation indicated thermal energy in the range of -48.4 to 72.4MJ/m(3) available for heat management. Further modeling and experimental analyses are needed to verify the effectiveness

    One of the major programs within the Office of Nuclear Energy, Science, and Technology of the US Department of Energy (DOE) is the depleted uranium hexafluoride (DUF{sub 6}) management program. The program is intended to find a long-term management strategy for the DUF{sub 6} that is currently stored in approximately 46,400 cylinders at Paducah, KY; Portsmouth, OH; and Oak Ridge, TN, USA. The program has four major components: technology assessment, engineering analysis, cost analysis, and the environmental impact statement (EIS). From the beginning of the program, the DOE has incorporated the environmental considerations into the process of strategy selection. Currently, the DOE has no preferred alternative. The results of the environmental impacts assessment from the EIS, as well as the results from the other components of the program, will be factored into the strategy selection process. In addition to the DOE`s current management plan, other alternatives continued storage, reuse, or disposal of depleted uranium, will be considered in the EIS. The EIS is expected to be completed and issued in its final form in the fall of 1997.

  8. Current issues in postoperative pain management.

    PubMed

    Rawal, Narinder

    2016-03-01

    Postoperative pain has been poorly managed for decades. Recent surveys from USA and Europe do not show any major improvement. Persistent postoperative pain is common after most surgical procedures, and after thoracotomy and mastectomy, about 50% of patients may experience it. Opioids remain the mainstay of postoperative pain treatment in spite of strong evidence of their drawbacks. Multimodal analgesic techniques are widely used but new evidence is disappointing. Regional anaesthetic techniques are the most effective methods to treat postoperative pain. Current evidence suggests that epidural analgesia can no longer be considered the 'gold standard'. Perineural techniques are good alternatives for major orthopaedic surgery but remain underused. Infiltrative techniques with or without catheters are useful for almost all types of surgery. Simple surgeon-delivered local anaesthetic techniques such as wound infiltration, preperitoneal/intraperitoneal administration, transversus abdominis plane block and local infiltration analgesia can play a significant role in improvement of postoperative care, and the last of these has changed orthopaedic practice in many institutions. Current postoperative pain management guidelines are generally 'one size fits all'. It is well known that pain characteristics such as type, location, intensity and duration vary considerably after different surgical procedures. Procedure-specific postoperative pain management recommendations are evidence based, and also take into consideration the role of anaesthetic and surgical techniques, clinical routines and risk-benefit aspects. The role of acute pain services to improve pain management and outcome is well accepted but implementation seems challenging. The need for upgrading the role of surgical ward nurses and collaboration with surgeons to implement enhanced recovery after surgery protocols with regular audits to improve postoperative outcome cannot be overstated.

    Fever is a very common complaint in children and is the single most common non-trauma-related reason for a visit to the emergency department. Parents are concerned about fever and it’s potential complications. The biological value of fever (i.e., whether it is beneficial or harmful) is disputed and it is being vigorously treated with the belief of preventing complications such as brain injury and febrile seizures. The practice of alternating antipyretics has become widespread at home and on paediatric wards without supporting scientific evidence. There is still a significant contrast between the current concept and practice, and the scientific evidence. Why is that the case in such a common complaint like fever The article will discuss the significant contrast between the current concepts and practice of fever management on one hand, and the scientific evidence against such concepts and practice.

    International agreements now recognize the role of forest in the mitigation of climate change through the levers of in-situ sequestration, storage in products and energy and product substitution. These three strategies of carbon management are often antagonistic and it is still not clear which strategy would have the most significant impact on atmospheric carbon concentrations. With a focus on France, this study compares several scenarios of forest management in terms of their effect on the overall carbon budget from trees to wood-products. We elaborated four scenarios of forest management that target different wood production objectives. One scenario is 'Business as usual' and reproduces the current forest management and wood production levels. Two scenarios target an increase in bioenergy wood production, with either long-term or short-term goals. One scenario aims at increasing the production of timber for construction. For this, an empirical regression model was developed building on the rich French inventory database. The model can project the current forest resource at a time horizon of 20 years for characteristic variables diameter, standing volume, above-ground biomass, stand age. A simplified life-cycle analysis provides a full carbon budget for each scenario from forest management to wood use and allows the identification of the scenario that most reduces carbon emissions.

    Current cancer treatments may create profound iatrogenic outcomes. The adverse effects of these treatments still remain, as the serious problems that practicing physicians have to cope with in clinical practice. Although, non-specific cytotoxic agents constitute an effective treatment modality against cancer cells, they also tend to kill normal, quickly dividing cells. On the other hand, therapies targeting the genome of the tumors are both under investigation, and some others are already streamlined to clinical practice. Several approaches have been investigated in order to find a treatment targeting the cancer cells, while not affecting the normal cells. Suicide gene therapy is a therapeutic strategy, in which cell suicide inducing transgenes are introduced into cancer cells. The two major suicide gene therapeutic strategies currently pursued are: cytosine deaminase/5-fluorocytosine and the herpes simplex virus/ganciclovir. The novel strategies include silencing gene expression, expression of intracellular antibodies blocking cells’ vital pathways, and transgenic expression of caspases and DNases. We analyze various elements of cancer cells’ suicide inducing strategies including: targets, vectors, and mechanisms. These strategies have been extensively investigated in various types of cancers, while exploring multiple delivery routes including viruses, non-viral vectors, liposomes, nanoparticles, and stem cells. We discuss various stages of streamlining of the suicide gene therapy into clinical oncology as applied to different types of cancer. Moreover, suicide gene therapy is in the center of attention as a strategy preventing cancer from developing in patients participating in the clinical trials of regenerative medicine. In oncology, these clinical trials are aimed at regenerating, with the aid of stem cells, of the patients’ organs damaged by pathologic and/or iatrogenic factors. However, the stem cells carry the risk of neoplasmic transformation. We

    Familial hypercholesterolemia is an autosomally dominant disorder caused by various mutations in low-density lipoprotein receptor genes. This will lead to elevated levels of total and low-density lipoprotein cholesterol, which may in turn lead to premature coronary atherosclerosis and cardiac-related death. The symptoms are more severe in the homozygous type of the disease. Different options for the treatment of affected patients are now available. Diet therapy, pharmacologic therapy, lipid apheresis, and liver transplantation are among the various treatments. We clinically review the treatment and management strategies for the disease in order to shed light on the optimal management of familial hypercholesterolemia. PMID:21191428

    A perioperative blood management program is one of a number of important elements for successful patient care in total knee arthroplasty (TKA) and surgeons should be proactive in its application. The aims of blood conservation are to reduce the risk of blood transfusion whilst at the same time maximizing hemoglobin (Hb) in the postoperative period, leading to a positive effect on outcome and cost. An individualized strategy based on patient specific risk factors, anticipated blood loss and comorbidities are useful in achieving this aim. Multiple blood conservation strategies are available in the preoperative, intraoperative and postoperative periods and can be employed in various combinations. Recent literature has highlighted the importance of preoperative Hb optimization, minimizing blood loss and evidence-based transfusion guidelines. Given TKA is an elective procedure, a zero allogenic blood transfusion rate should be the aim and an achievable goal. PMID:27595070

  16. A Water Demand Management Strategy For The Namibian Tourism Sector

    NASA Astrophysics Data System (ADS)

    Schachtschneider, K.; Winter, K.

    The arid conditions of Namibia are forcing its decision-makers to resort to new wa- ter resource management approaches, including Water Demand Management (WDM). When Namibia achieved its independence from South Africa 1990, a new opportunity arose to rewrite certain restrictive laws and policies in order to bring about redress, development and transformation. The new Water Policy is one example in which the mindset is changed from a supply to a demand oriented water management ap- proach. Legal support for WDM within the new Water Act is a critical component that will support the implementation of WDM in all economic sectors, such as agri- culture, mining and tourism. It is argued that an appropriate WDM strategy should be designed specifically for each sector, once the typical water use patterns in a sec- tor are understood and key water resource managers at all levels are identified. The Namibian tourism sector is geographically dispersed and control over its operations is compounded by the fact that it is frequently located in extremely remote areas that are arid and ecologically sensitive. In general, WDM is rarely practised, because it is not yet supported by law and there are currently no institutional arrangements to con- trol water use in this geographically dispersed industrial sector through which WDM could be enforced either through metering and/or payments. Managers of tourist en- terprises undertake most of the water management themselves, and have been identi- fied as being crucial to the implementation of WDM strategies. A study of six tourist facilities determined the willingness and motivation of these managers to undertake various WDM initiatives. The study identified three factors which appear to influence the actions of managers, namely external controls, economics and company ethics. It is recommended that a tourism sector WDM strategy should focus on these three factors in order to transform the WDM aims and objectives on the policy level into

    Background Supraventricular tachycardia (SVT) is a general term describing a group of arrhythmias whose mechanism involves or is above the atrioventricular node. The mechanisms of most forms of SVT have been elucidated, and pharmacologic and invasive therapies have evolved simultaneously. Methods We provide a brief overview of the mechanisms, classifications, and electrocardiographic characteristics of different SVTs and describe current trends in noninvasive and invasive therapies. Results The term SVT encompasses a heterogeneous group of arrhythmias with different electrophysiologic characteristics. Knowledge of the mechanism of each SVT is important in determining management at the bedside and in the electrophysiology laboratory. Conclusion In the acute setting, vagal maneuvers and pharmacologic therapy can be effective in arrhythmia termination. Catheter-based radiofrequency ablation has revolutionized therapy for many SVTs, and newer techniques have significantly improved ablation efficacy and reduced periprocedural complications and procedure times. Cryoablation is currently being investigated as an alternative form of energy delivery, although the long-term effectiveness of this procedure currently limits its use for many SVTs. PMID:25598724

  19. Invasive mycoses: strategies for effective management.

    PubMed

    Kontoyiannis, Dimitrios P

    2012-01-01

    Effective management of invasive fungal infections (IFIs) depends on early individualized therapy that optimizes efficacy and safety. Considering the negative consequences of IFI, for some high-risk patients the potential benefits of prophylactic therapy may outweigh the risks. When using a prophylactic, empiric, or preemptive therapeutic approach, clinicians must take into account the local epidemiology, spectrum of activity, pharmacokinetic and pharmacodynamic parameters, and safety profile of different antifungal agents, together with unique host-related factors that may affect antifungal efficacy or safety. Therapeutic drug monitoring is increasingly recognized as important or necessary when employing lipophilic triazoles (itraconazole, voriconazole, posaconazole) or flucytosine. Because early diagnostics remain limited for uncommon, yet emerging opportunistic molds (e.g., Mucorales), and treatment delay is associated with increased mortality, early effective management often depends on a high index of suspicion, taking into account predisposing factors, host cues favoring mucormycosis, and local epidemiology. Antifungal options for mucormycosis are limited, and optimal management depends on a multimodal approach that includes early diagnosis/clinical suspicion, correction of underlying predisposing factors, radical debridement of affected tissues, and extended antifungal therapy. This article discusses strategies for the effective management of invasive mycoses, with a particular focus on antifungal hepatotoxicity. PMID:22196206

    The issue of antenatal hydronephrosis has become a routine component for the care of a pregnant woman despite limited evidence of a clinical benefit. The genitourinary tract represents the most commonly detected organ system with identified abnormalities, with antenatal hydronephrosis (ANH), being the most notable and common finding. ANH represents a spectrum, with most cases being a trivial and inconsequential finding on maternal fetal ultrasound. However, there is a correlation with increased grades of ANH being associated with increased severity of urinary tract pathology. Most patients can be managed expectantly with appropriate evaluation commenced postnatally based on severity of ANH and proper parental counseling and education. The purpose of this review was to assess current literature and guidelines pertaining to ANH and incorporate our practical interpretations of their significance. PMID:23325322

    Each of three agents used in the treatment of duodenal ulcer--magnesium--aluminum antacids in high doses, cimetidine and carbenoxolone sodium--appears to enhance the rate at which ulcers heal, although their ability to control symptoms has been less clearly demonstrated. Since a large proportion of ulcers heal either without treatment or when the patient is given a placebo, a rational management plan should emphasize the removal of known irritants and the provision of symptomatic relief while spontaneous healing is allowed to occur. Lack of response to such a regimen warrants more specific investigation and therapy. On the basis of current evidence, cimetidine appears to be the preferred therapeutic agent. PMID:603851

    Glaucoma is a neurodegenerative disease characterized by retinal ganglion cell (RGC) death and axonal loss. It remains a major cause of blindness worldwide. All current modalities of treatment are focused on lowering intraocular pressure (IOP), and it is evident that increased IOP is an important risk factor for progression of the disease. However, it is clear that a significant number of glaucoma patients show disease progression despite of pressure lowering treatments. Much attention has been given to the development of neuroprotective treatment strategies, but the identification of such has been hampered by lack of understanding of the etiology of glaucoma. Hence, in spite of many attempts no neuroprotective drug has yet been clinically approved. Even though neuroprotection is without doubt an important treatment strategy, many glaucoma subjects are diagnosed after substantial loss of RGCs. In this matter, recent approaches aim to rescue RGCs and regenerate axons in order to restore visual function in glaucoma. The present review seeks to provide an overview of the present and new treatment strategies in the management of glaucoma. The treatment strategies are divided into current available glaucoma medications, new pressure lowering targets, prospective neuroprotective interventions, and finally possible neuroregenrative strategies.

    Objectives Patient-reported experience measures are increasingly being used to routinely monitor the quality of care. With the increasing attention on such measures, hospital managers seek ways to systematically improve patient experience across hospital departments, in particular where outcomes are used for public reporting or reimbursement. However, it is currently unclear whether hospitals with more mature quality management systems or stronger focus on patient involvement and patient-centered care strategies perform better on patient-reported experience. We assessed the effect of such strategies on a range of patient-reported experience measures. Materials and Methods We employed a cross-sectional, multi-level study design randomly recruiting hospitals from the Czech Republic, France, Germany, Poland, Portugal, Spain, and Turkey between May 2011 and January 2012. Each hospital contributed patient level data for four conditions/pathways: acute myocardial infarction, stroke, hip fracture and deliveries. The outcome variables in this study were a set of patient-reported experience measures including a generic 6-item measure of patient experience (NORPEQ), a 3-item measure of patient-perceived discharge preparation (Health Care Transition Measure) and two single item measures of perceived involvement in care and hospital recommendation. Predictor variables included three hospital management strategies: maturity of the hospital quality management system, patient involvement in quality management functions and patient-centered care strategies. We used directed acyclic graphs to detail and guide the modeling of the complex relationships between predictor variables and outcome variables, and fitted multivariable linear mixed models with random intercept by hospital, and adjusted for fixed effects at the country level, hospital level and patient level. Results Overall, 74 hospitals and 276 hospital departments contributed data on 6,536 patients to this study (acute

    Atlantoaxial dislocation (AAD), often caused by trauma, tumors or congenital malformations, is a challenging disorder of the craniocervical junction. Because of its deep location and intricate anatomic structure, the craniocervical junction is always a difficult region for spine surgery. With recent developments in medical science, great progress has been made in the diagnosis and treatment of AAD such that more instructive clinical classifications and efficacious treatment strategies, various novel operation techniques including innovative posterior or transoral anterior reduction, and novel fixation instruments are now widely used in clinical practice for managing AAD. However, surgeons continue to face more special characteristics and difficulty in carrying out upper cervical surgery than they encounter in other regions of the spine. Consequently, this high risk surgery should only be performed by extremely skilled and experienced surgeons and only when stringent indications have been met. Therefore, the aim of this course is to assist surgeons who are dealing with AAD by providing comprehensive information about AAD, including related anatomy, classification, clinical manifestations and diagnosis, imaging examinations and surgical techniques, thus decreasing the occurrence of complications and improving the level of diagnosis and treatment.

    Current understanding of the term "concussion" is fraught with misconceptions regarding the extent and nature of brain injury. Despite increasing attention in popular media and within the context of sports, considerable gaps exist in our knowledge of the diagnosis, underlying brain pathology, recovery of function, and optimal interventions for concussion. In this special interest article, we discuss the definition and risk factors associated with concussion, summarize and highlight some of the most widely used assessment tools, and critique the evidence for current principles of concussion management. Our evaluation has identified opportunities for novel neuroimaging techniques to improve the understanding of the pathophysiology of concussion and to evaluate the changes in the recovering brain in response to rehabilitation. In summary, a clear definition of the underlying brain pathology, the potential long-term consequences, and the risk factors of injury and recovery will help guide future research aiming to minimize the impact of injury and develop innovative and successful therapeutic approaches aimed at ameliorating the functional impairments associated with concussion.

    The acute scrotum is a challenging condition for the treating emergency physician requiring consideration of a number of possible diagnoses including testicular torsion. Prompt recognition of torsion and exclusion of other causes may lead to organ salvage, avoiding the devastating functional and psychological issues of testicular loss and minimizing unnecessary exploratory surgeries. This review aims to familiarize the reader with the latest management strategies for the acute scrotum, discusses key points in diagnosis and management and evaluates the strengths and drawbacks of history and clinical examination from an emergency perspective. It outlines the types and mechanisms of testicular torsion, and examines the current and possible future roles of labwork and radiological imaging in diagnosis. Emergency departments should be wary of younger males presenting with the acute scrotum. PMID:26267075

    Multiple system atrophy (MSA) is a rare neurodegenerative disorder without any effective treatment in slowing or stopping disease progression. It is characterized by poor levodopa responsive Parkinsonism, cerebellar ataxia, pyramidal signs and autonomic failure in any combination. Current therapeutic strategies are primarily based on dopamine replacement and improvement of autonomic failure. However, symptomatic management remains disappointing and no curative treatment is yet available. Recent experimental evidence has confirmed the key role of alpha-synuclein aggregation in the pathogenesis of MSA. Referring to this hypothesis, transgenic and toxic animal models have been developed to assess candidate drugs for MSA. The standardization of diagnosis criteria and assessment procedures will allow large multicentre clinical trials to be conducted. In this article we review the available symptomatic treatment, recent results of studies investigating potential neuroprotective drugs, and future approaches for the management in MSA. PMID:21179616

    Background: Instead of waiting for challenges to confront hospital management, doctors and managers should act in advance to optimize and sustain value-based health. This work highlights the importance of scenario planning in hospitals, proposes an elaborated definition of the stakeholders of a hospital and defines the influence factors to which hospitals are exposed to. Methodology: Based on literature analysis as well as on personal interviews with stakeholders we propose an elaborated definition of stakeholders and designed a questionnaire that integrated the following influence factors, which have relevant impact on hospital management: political/legal, economic, social, technological and environmental forces. These influence factors are examined to develop the so-called critical uncertainties. Thorough identification of uncertainties was based on a “Stakeholder Feedback”. Results: Two key uncertainties were identified and considered in this study: the development of workload for the medical staff the profit oriented performance of the medical staff. According to the developed scenarios, complementary education of the medical staff as well as of non-medical top executives and managers of hospitals was the recommended core strategy. Complementary scenario-specific strategic options should be considered whenever needed to optimize dealing with a specific future development of the health care environment. Conclusion: Strategic planning in hospitals is essential to ensure sustainable success. It considers multiple situations and integrates internal and external insights and perspectives in addition to identifying weak signals and “blind spots”. This flows into a sound planning for multiple strategic options. It is a state of the art tool that allows dealing with the increasing challenges facing hospital management. PMID:26504735

    2012-09-01

    The liver is the most frequently injured organ during abdominal trauma. The management of hepatic trauma has undergone a paradigm shift over the past several decades, with mandatory operation giving way to nonoperative treatment. Better understanding of the mechanisms and grade of liver injury aids in the initial assessment and establishment of a management strategy. Hemodynamically unstable patients should undergo focused abdominal sonography for trauma, whereas stable patients may undergo computed tomography, the standard examination protocol. The grade of liver injury alone does not accurately predict the need for operation, and nonoperative management is rapidly becoming popular for high-grade injuries. Hemodynamic instability with positive focused abdominal sonography for trauma and peritonitis is an indicator of the need for emergent operative intervention. The damage control concept is appropriate for the treatment of major liver injuries and is associated with significant survival advantages compared with traditional prolonged surgical techniques. Although surgical intervention for hepatic trauma is not as common now as it was in the past, current trauma surgeons should be familiar with the emergency surgical skills necessary to manage complex hepatic injuries, such as packing, Pringle maneuver, selective vessel ligation, resectional debridement, and parenchymal sutures. The present review presents emergency strategies and trends in the management of liver trauma. PMID:22673827

    2014-01-01

    Scholars have studied the various pressures that companies face related to socially responsible behavior when stakeholders know the particular social issues under consideration. Many have examined social responsibility in the context of environmental responsibility and the general approaches companies take regarding environmental management. The issue of currently unregulated, but potentially hazardous, chemicals in consumer products is not well understood by the general public, but a number of proactive consumer product companies have voluntarily adopted strategies to minimize use of such chemicals. These companies are exceeding regulatory requirements by restricting from their products chemicals that could harm human or environmental health, despite the fact that these actions are costly. They do not usually advertise the details of their strategies to end consumers. This article uses interviews with senior environmental directors of 20 multinational consumer product companies to investigate why these companies engage in voluntary chemicals management. The authors conclude that the most significant reasons are to achieve a competitive advantage and stay ahead of regulations, manage relationships and maintain legitimacy with stakeholders, and put managerial values into practice. Many of the characteristics related to the case of chemicals management are extendable to other areas of stakeholder management in which risks to stakeholders are either unknown or poorly understood.

    Balancing increased spending for specialty pharmaceuticals while providing affordable and equitable coverage for consumers is a key issue for public and private payers. Health plans rely on an array of strategies, including both medical management and those used for more traditional pharmaceuticals. To explore specific management strategies for outpatient specialty pharmaceuticals, a survey was administered to thirty-eight Blue Cross and Blue Shield plans, focused on identifying core strategies. Prior authorization was the most commonly used strategy, implemented by 83.3 percent of respondents. Other frequently implemented management strategies included claims review (82.8 percent), formulary management (76.7 percent), and utilization review (70 percent). PMID:16966730

    Osteosarcoma is the most frequent malignant primary bone tumor and a main cause of cancer-related death in children and adolescents. Although long-term survival in localized osteosarcoma has improved to about 60% during the 1960s and 1970s, long-term survival in both localized and metastatic osteosarcoma has stagnated in the past several decades. Thus, current conventional therapy consists of multi-agent chemotherapy, surgery and radiation, which is not fully adequate for osteosarcoma treatment. Innovative drugs and approaches are needed to further improve outcome in osteosarcoma patients. This review describes the current management of osteosarcoma as well as potential new therapies.

    Background Cardiorenal syndrome (CRS) encompasses conditions in which cardiac and renal disorders co-exist and are pathophysiologically related. The newest classification of CRS into seven etiologically and clinically distinct types for direct patient management purposes includes hemodynamic, uremic, vascular, neurohumoral, anemia- and/or iron metabolism-related, mineral metabolism-related and protein-energy wasting-related CRS. This classification also emphasizes the pathophysiologic pathways. The leading CRS category remains hemodynamic CRS, which is the most commonly encountered type in patient care settings and in which acute or chronic heart failure leads to renal impairment. Summary This review focuses on selected therapeutic strategies for the clinical management of hemodynamic CRS. This is often characterized by an exceptionally high ratio of serum urea to creatinine concentrations. Loop diuretics, positive inotropic agents including dopamine and dobutamine, vasopressin antagonists including vasopressin receptor antagonists such as tolvaptan, nesiritide and angiotensin-neprilysin inhibitors are among the pharmacologic agents used. Additional therapies include ultrafiltration (UF) via hemofiltration or dialysis. The beneficial versus unfavorable effects of these therapies on cardiac decongestion versus renal blood flow may act in opposite directions. Some of the most interesting options for the outpatient setting that deserve revisiting include portable continuous dobutamine infusion, peritoneal dialysis and outpatient UF via hemodialysis or hemofiltration. Key Messages The new clinically oriented CRS classification system is helpful in identifying therapeutic targets and offers a systematic approach to an optimal management algorithm with better understanding of etiologies. Most interventions including UF have not shown a favorable impact on outcomes. Outpatient portable dobutamine infusion is underutilized and not well studied. Revisiting traditional and

    Multidrug resistance (MDR) is a major impediment to the success of cancer chemotherapy. P-glycoprotein is an important and the best-known membrane transporter involved in MDR. Several strategies have been used to address MDR, especially P-glycoprotein-mediated drug resistance in tumors. However, clinical success has been limited, largely due to issues regarding lack of efficacy and/or safety. Nanoparticles have shown the ability to target tumors based on their unique physical and biological properties. To date, nanoparticles have been investigated primarily to address P-glycoprotein and the observed improved anticancer efficacy suggests that nanomedicinal strategies provide a new opportunity to overcome MDR. This article focuses on nanotechnology-based formulations and current nanomedicine approaches to address MDR in tumors and discusses the proposed mechanisms of action. PMID:20528455

    Pediatric soft tissue sarcomas are a group of malignant neoplasms arising within embryonic mesenchymal tissues during the process of differentiation into muscle, fascia and fat. The tumors have a biphasic peak for age of incidence. Rhabdomyosarcoma (RMS) is diagnosed more frequently in younger children, whereas adult-type non-RMS soft tissue sarcoma is predominately observed in adolescents. The latter group comprises a variety of rare tumors for which diagnosis can be difficult and typically requires special studies, including immunohistochemistry and molecular genetic analysis. Current management for the majority of pediatric sarcomas is based on the data from large multi-institutional trials, which has led to great improvements in outcomes over recent decades. Although surgery remains the mainstay of treatment, the curative aim cannot be achieved without adjuvant treatment. Pre-treatment staging and risk classification are of prime importance in selecting an effective treatment protocol. Tumor resectability, the response to induction chemotherapy, and radiation generally determine the risk-group, and these factors are functions of tumor site, size and biology. Surgery provides the best choice of local control of small resectable tumors in a favorable site. Radiation therapy is added when surgery leaves residual disease or there is evidence of regional spread. Chemotherapy aims to reduce the risk of relapse and improve overall survival. In addition, upfront chemotherapy reduces the aggressiveness of the required surgery and helps preserve organ function in a number of cases. Long-term survival in low-risk sarcomas is feasible, and the intensity of treatment can be reduced. In high-risk sarcoma, current research is allowing more effective disease control. PMID:26566481

    Wedged between the growing cost of environmental compliance and consumer protests over prices, the downstream oil and gas and petrochemical business segments are having to accelerate the changes that have engulfed their industry. Despite recent price increases, thinning margins have driven energy companies to rethink their role in life and to revaluate and reshape operations and assets in pursuit of new strategies. As companies concentrate on core competencies, shift to demand-pull production, and try to leverage their clout in selected regions for market dominance, performance of key operations has become paramount. In theory, performance management is a simple, straightforward proposition. It means deploying a comprehensive, strategy-linked framework for measuring performance across the entire enterprise and then using the results of these measurements to serve two critical managerial functions. First, performance measurement is the means for making informed, knowledge-based decisions about important business issues such as minimizing operational costs, manufacturing the right mix of products, identifying the most profitable distribution channels, and optimizing the utilization of assets. Second -- and in the long run more importantly -- measuring performance is a means for identifying and addressing areas where a company needs to make the kinds of organizational and process improvements that can develop, sustain, and amplify competitive advantage over the long haul. Experiences at a variety of companies, both within and outside the oil and gas and chemical business segments, demonstrate that progress towards comprehensive performance management is possible, with quantifiable benefits and results. Competitive advantage will be enjoyed by those companies that advance further and faster down this path.

    The purpose of this investigation is to evaluate the current status and to identify the problems of municipal solid waste (MSW) management in China to determine appropriate remedial strategies. This is the second of two papers proposed on this topic. Major problems or difficulties identified in MSW management in China include MSW land, air, and water pollution, commingled collection, poor administration, shortage of funds, lack of facilities, and problems of training and public awareness. In order to solve these problems and to improve MSW management in China, remedial strategies in three areas are recommended: institutional reform, technology development, and legislation and administrative improvement. The primary principle involved in institutional reform is unifying legislative responsibilities into one body and developing a market mechanism for handling MSW. Composting, landfills, and incineration should be equally developed in accordance with China's needs. The feasibility of developing technology to handle MSW in China is discussed. Also recommended is the establishment of sound regulatory systems, including a service fee system, a source separation system, and a training program. China is presently undergoing economic and institutional reform at the national and local levels. Results of this study will provide useful information on MSW management in China. PMID:11256501

    Premature ejaculation (PE) is a common sexual disorder in men that is mediated by disturbances in the peripheral and central nervous systems. Although all pharmaceutical treatments for PE are currently used ‘off-label', some novel oral agents and some newer methods of drug administration now provide important relief to PE patients. However, the aetiology of this condition has still not been unified, primarily because of the lack of a standard animal model for basic research and the absence of a widely accepted definition and assessment tool for evidence-based clinical studies in patients with PE. In this review, we focus on the current therapeutic strategies and future treatment perspectives for PE. PMID:21532601

    2013-11-01

    Leber's hereditary optic neuropathy (LHON) is a rare mitochondrial retinopathy, caused by mutations in subunits of complex I of the respiratory chain, which leads to elevated levels of oxidative stress and an insufficient energy supply. This molecular pathology is thought to be responsible for the dysfunction and eventual apoptotic loss of retinal ganglion cells in the eye, which ultimately results in blindness. Many strategies, ranging from neuroprotectants, antioxidants, anti-apoptotic- and anti-inflammatory compounds have been tested with mixed results. Currently, the most promising compounds are short-chain quinones that have been shown to protect the vision of LHON patients during the early stages of the disease. This commentary gives a brief overview on the current status of tested therapeutics and also addresses future developments such as the use of gene therapy that hopefully will provide safe and efficient therapy options for all LHON patients.

    Despite continued advances in urological surgery, erectile dysfunction (ED) remains a serious adverse effect of radical prostatectomy. In this setting, ED is predominantly caused by injury to the neurovascular bundles, which lie alongside the prostate and are responsible for initiating and maintaining the erectile response. Most men will experience some degree of ED after radical prostatectomy, although erectile function outcomes have already remarkably improved since the development of nerve-sparing surgical techniques. To further improve outcomes, erection rehabilitation strategies are being investigated, which emphasize early treatment regimens with the aim of preventing adverse remodelling after surgery and preserving erectile function. Strategies include pharmacological therapy, mechanical therapy and psychosocial support. In addition, novel therapeutic approaches involving new targets for small-molecule treatments and regenerative medicine therapies are being developed to aid in restoring erectile function. Although ED treatments can be effective following radical prostatectomy, no specific erection rehabilitation regimen has currently been shown to be superior to other investigated rehabilitation regimens. Nevertheless, the different strategies rightfully remain an area of intensive research, as preservation of erectile function is a critical part of providing comprehensive care for men with prostate cancer to ensure their overall well-being, in contrast to just treating a patient's tumour.

    Approximately 90% of diabetes cases in pregnant women are considered gestational diabetes mellitus (GDM). It is well known that uncontrolled glucose results in poor pregnancy outcomes in both the mother and fetus. Worldwide there are many guidelines with recommendations for appropriate management strategies for GDM once lifestyle modifications have been instituted and failed to achieve control. The efficacy and particularly the safety of other treatment modalities for GDM has been the source of much debate in recent years. Studies that have demonstrated the safety and efficacy of both glyburide and metformin in the management of patients with GDM will be reviewed. There is a lack of evidence with other oral and injectable non-insulin agents to control blood glucose in GDM. The role of insulin will be discussed, with emphasis on insulin analogs. Ideal patient characteristics for each treatment modality will be reviewed. In addition, recommendations for postpartum screening of patients will be described as well as recommendations for use of agents to manage subsequent type 2 diabetes in patients who are breastfeeding.

    NASA is currently developing the propulsion system concepts for human exploration missions to the lunar surface. The propulsion concepts being investigated are considering the use of cryogenic propellants for the low gravity portion of the mission, that is, the lunar transit, lunar orbit insertion, lunar descent and the rendezvous in lunar orbit with a service module after ascent from the lunar surface. These propulsion concepts will require the vapor free delivery of the cryogenic propellants stored in the propulsion tanks to the exploration vehicles main propulsion system (MPS) engines and reaction control system (RCS) engines. Propellant management devices (PMD s) such as screen channel capillary liquid acquisition devices (LAD s), vanes and sponges currently are used for earth storable propellants in the Space Shuttle Orbiter OMS and RCS applications and spacecraft propulsion applications but only very limited propellant management capability exists for cryogenic propellants. NASA has begun a technology program to develop LAD cryogenic fluid management (CFM) technology through a government in-house ground test program of accurately measuring the bubble point delta-pressure for typical screen samples using LO2, LN2, LH2 and LCH4 as test fluids at various fluid temperatures and pressures. This presentation will document the CFM project s progress to date in concept designs, as well ground testing results.

    Cholangiocarcinoma (CC) accounts for about 3% of all gastrointestinal tumors and is the second most common primary liver tumor. Quality guidelines on CC are needed to guide hepatobiliary surgeons. Here, current guidelines on CC were reviewed to provide useful information and suggestions to help institutes and organizations all around the world to draft better guidelines on CC. Literature databases were electronically searched to identify guidelines or consensus statements regarding CC published from 2002-2016. Nine guidelines were included in this review. Comparison of the current guidelines revealed several inconsistencies. Signs of conflicting views indicated a lack of high level evidence. More studies need to be conducted in areas of contention to help update the guidelines. Organizations and medical societies need to be encouraged to use standard evaluation measures, to restrict tumors to CC or iCC, pCC, or dCC specifically, to give recommendations in accordance with the equipment that is available for diagnosis and treatment in different counties, and to use an appropriate and consistent structure when establishing and drafting guidelines for CC.

This can be attributed, among other factors, to tumour recurrences inside or outside the treated area, and metastases at more distal locations. These tumours therefore require not only the standard surgical and radiation treatments, but also effective systemic modalities. The main option here is antineoplastic chemotherapy, which is firmly established in the palliative treatment of recurrent or metastatic stages of disease, and is used with curative intent in the form of combined simultaneous or adjuvant chemoradiotherapy in patients with inoperable or advanced tumour stages. Neoadjuvant treatment strategies for tumour reduction before surgery have yet to gain acceptance. Induction chemotherapy protocols before radiotherapy have to date been used in patients at high risk of distant metastases or as an aid for decision-making (“chemoselection”) in those with extensive laryngeal cancers, prior to definitive chemoradiotherapy or laryngectomy. Triple-combination induction therapy (taxanes, cisplatin, 5-fluorouracil) shows high remission rates with significant toxicity and, in combination with (chemo-)radiotherapy, is currently being compared with simultaneous chemoradiotherapy; the current gold standard with regards to efficacy and long-term toxicity. A further systemic treatment strategy, called “targeted therapy”, has been developed to help increase specificity and reduce toxicity. An example of targeted therapy, EGFR-specific antibodies, can be used in palliative settings and, in combination with radiotherapy, to treat advanced head and neck cancers. A series of other novel biologicals such as signal cascade inhibitors, genetic agents, or immunotherapies, are currently being evaluated in large-scale clinical studies, and could prove useful in patients with advanced, recurring or metastatic head and neck cancers.

    Malignant pleural effusion (MPE) can complicate most malignancies and is a common clinical problem presenting to respiratory and cancer care physicians. Despite its frequent occurrence, current knowledge of MPE remains limited and controversy surrounds almost every aspect in its diagnosis and management. A lack of robust data has led to significant practice variations worldwide, inefficiencies in healthcare provision, and threats to patient safety. Recent studies have highlighted evolving concepts in MPE care that challenge traditional beliefs. Advancing laboratory techniques have improved the diagnostic yield from pleural fluid cytology, minimizing the need for invasive tissue biopsies, even in many cases of mesothelioma. Imaging-guided biopsy is comparable to thoracoscopy in suitable patients, if cytological examination was noncontributory. Cumulating evidence for the benefits of indwelling pleural catheters (IPCs) has led some centers to adopt this approach as first-line definitive management for MPE over conventional talc pleurodesis. The optimal technique of talc pleurodesis is still debated despite its use for many decades. Strategies combining pleurodesis and IPC are being studied. MPE consists of a heterogenous group of diseases and careful phenotyping of malignant effusion patients can provide important clinical information that will advance the field and allow better stratification of patients and planning of therapy accordingly. This review addresses the controversies in MPE diagnosis and management and exposes the deficits in knowledge of MPE that should be the focus of future research. PMID:25463163

    The care and management of patients with chronic wounds and their far-reaching effects challenge both the patient and the practitioner. Further complicating this situation is the paucity of evidence-based treatment strategies for chronic wound care. After searching both MEDLINE and Cochrane databases, we reviewed currently available articles concerning chronic wound care. Utilizing this information, we have outlined a review of current, evidence-based concepts as they pertain to the treatment of chronic wounds, focusing on fundamental treatment principles for the management of venous, arterial, diabetic, and pressure ulcers. Individualized treatment options as well as general wound management principles applicable to all varieties of chronic wounds are described. Classification and treatment guidelines as well as the adoption of the TIME acronym facilitate an organized conceptional approach to wound care. In so doing, individual aspects of generalized wound care such as debridement, infection, and moisture control as well as attention to the qualities of the wound edge are comprehensively evaluated, communicated, and addressed. Effective adjuvant agents for the therapy of chronic wounds including nutritional and social support measures are listed, as is a brief review of strategies helpful for preventing recurrence. An appreciation of evidence-based treatment pathways and an understanding of the pathophysiology of chronic wounds are important elements in the management of patients with chronic wounds. To achieve effective and long-lasting results, a multidisciplinary approach to patient care, focused on the education and coordination of patient, family as well as medical and support staff can prove invaluable.

    2006-01-01

    Obesity is a chronic relapsing disease requiring a similar long term approach to management as that of other chronic conditions. Management needs to be multifaceted aiming to achieve sustainable behavioural changes to physical activity and diet to alter the patient and family microenvironment to one favouring better weight control. A range of therapies including specific diets, calorie counting, meal replacements, very low calorie diets, pharmacotherapy, intragastric balloons and surgery can provide very useful additional benefit. Use of these should be guided by the extent of weight loss required to reduce BMI to an acceptable level with regard to the patient's ethnicity, risk and comorbid conditions. Patients need to set goals that are optimistic, but realistic, and understand the benefits of sustained modest weight loss and the likelihood of weight regain requiring repeat episodes of weight loss. Practitioners need to be informed about the efficacy of current therapies and their combinations to enhance choice of suitable methods for achieving the optimal weight loss required by the patient. They will also need to anticipate trigger points for renewed periods of weight loss in the event of weight regain, as relapse is likely but not a reason for abandoning the battle. PMID:16928663

    Priapism is a persistent penile erection that continues for hours beyond, or is unrelated to, sexual stimulation. Priapism requires a prompt evaluation and usually requires an emergency management. There are two types of priapism: 1) ischemic (veno-occlusive or low-flow), which is found in 95% of cases, and 2) nonischemic (arterial or high-flow). Stuttering (intermittent or recurrent) priapism is a recurrent form of ischemic priapism. To initiate appropriate management, the physician must decide whether the priapism is ischemic or nonischemic. In the management of an ischemic priapism, resolution should be achieved as promptly as possible. Initial treatment is therapeutic aspiration with or without irrigation of the corpora. If this fails, intracavernous injection of sympathomimetic agents is the next step. Surgical shunts should be performed in cases involving failure of nonsurgical treatment. The first management of a nonischemic priapism should be observation. Selective arterial embolization is recommended for the management of nonischemic priapism in cases that request treatment. The goal of management for stuttering priapism is prevention of future episodes. This article provides a review of recent clinical developments in the medical and surgical management of priapism and an investigation of scientific research activity in this rapidly developing field of study.

  1. Steam generator degradation: Current mitigation strategies for controlling corrosion

    SciTech Connect

    Millett, P.

    1997-02-01

    Steam Generator degradation has caused substantial losses of power generation, resulted in large repair and maintenance costs, and contributed to significant personnel radiation exposures in Pressurized Water Reactors (PWRs) operating throughout the world. EPRI has just published the revised Steam Generator Reference Book, which reviews all of the major forms of SG degradation. This paper discusses the types of SG degradation that have been experienced with emphasis on the mitigation strategies that have been developed and implemented in the field. SG degradation is presented from a world wide perspective as all countries operating PWRs have been effected to one degree or another. The paper is written from a US. perspective where the utility industry is currently undergoing tremendous change as a result of deregulation of the electricity marketplace. Competitive pressures are causing utilities to strive to reduce Operations and Maintenance (O&M) and capital costs. SG corrosion is a major contributor to the O&M costs of PWR plants, and therefore US utilities are evaluating and implementing the most cost effective solutions to their corrosion problems. Mitigation strategies developed over the past few years reflect a trend towards plant specific solutions to SG corrosion problems. Since SG degradation is in most cases an economic problem and not a safety problem, utilities can focus their mitigation strategies on their unique financial situation. Accordingly, the focus of R&D has shifted from the development of more expensive, prescriptive solutions (e.g. reduced impurity limits) to corrosion problems to providing the utilities with a number of cost effective mitigation options (e.g. molar ratio control, boric acid treatment).

    The atmospheric pathway of the global mercury cycle is known to be the primary source of mercury contamination to most threatened aquatic ecosystems. While much effort has been made to quantify the total mass flux of mercury to the atmosphere from various natural and anthropogenic sources, discrimination of the chemical and physical forms of these emissions is just beginning in response to early modeling exercises showing this discrimination to be critical for accurate modeling estimates of the sources responsible for observed mercury deposition. In this paper, current atmospheric mercury modeling techniques and the information obtained from them are described. A strategy for future field research and numerical model development is proposed which is designed to confidently identify the sources of atmospheric mercury responsible for observed contamination of aquatic ecosystems.

    One of the chief contemporary goals of neurologists and neuroscientists is to find a way to overcome the debilitating effects of brain diseases, especially neurodegenerative diseases. Since very few molecules have been found to be efficient in curing the patients and even halting the progression of the symptoms, cell therapy is now seen as an attractive alternative. Two therapeutic strategies are currently under investigation: i) the "substitution" strategy, based on grafts of cells capable of differentiating in the appropriate cells and restoring lost functions and ii) the "neuroprotective" or "conservative" strategy aiming to increase the resistance of spared cells to the toxicity of their environment and to reinforce the body's own mechanisms of healing. Twenty years ago, foetal neuroblasts were the first cells to be transplanted in the brains of patients with Parkinson's or Huntington disease. A phase II clinical trial is presently conducted in France for the latter disorder. However, the numerous ethical and technical issues raised by the use of embryonic and foetal cells have directed the focus of clinicians and researchers towards substitute cell types. In this review, we summarise the main findings of the most recent basic studies and clinical trials based on: i) the grafting of surrogate adult cells such as bone marrow mesenchymal stem cells and olfactory ensheathing cells; ii) the potential therapeutic applications of neuropoiesis - the persistent neurogenesis in the brain - as a source for tissue engraftment and as self-repair by a person's own indigenous population of pluripotent cells and iii) immune-based therapy (autologous activated macrophages and T cell vaccination) as well as administration of immunomodulatory molecules. Unexpectedly, it has been found that undifferentiated adult stem cells can display immune-like functions when they home in on an inflamed brain area while immune cells and immunosuppressors can improve functional and

    Despite >100 clinical trials, only 2 new drugs had been approved by the US Food and Drug Administration for the treatment of chronic heart failure in more than a decade: the aldosterone antagonist eplerenone in 2003 and a fixed dose combination of hydralazine-isosorbide dinitrate in 2005. In contrast, 2015 has witnessed the Food and Drug Administration approval of 2 new drugs, both for the treatment of chronic heart failure with reduced ejection fraction: ivabradine and another combination drug, sacubitril/valsartan or LCZ696. Seemingly overnight, a range of therapeutic possibilities, evoking new physiological mechanisms, promise great hope for a disease that often carries a prognosis worse than many forms of cancer. Importantly, the newly available therapies represent a culmination of basic and translational research that actually spans many decades. This review will summarize newer drugs currently being used in the treatment of heart failure, as well as newer strategies increasingly explored for their utility during the stages of the heart failure syndrome.

    Atrial fibrillation (AF) is the most commonly encountered arrhythmia in clinical practice. Aging populations coupled with improved outcomes for many chronic medical conditions has led to increases in AF diagnoses. AF is also known to be associated with an increased risk of adverse events such as transient ischemic attack, ischemic stroke, systemic embolism, and death. This association is enhanced in select populations with preexisting comorbid conditions such as chronic heart failure. The aim of this review is to highlight the advances in the field of cardiology in the management of AF in both acute and long-term settings. We will also review the evolution of anticoagulation management over the past few years and landmark trials in the development of novel oral anticoagulants (NOACs), reversal agents for new NOACs, nonpharmacological options to anticoagulation therapy, and the role of implantable loop recorder in AF management.

    In recent years, many environmental problems have become important factors in promoting the economic need to develop tourist activity: climate change such as energy wars, increasing hunger and aridity, population increases in urban areas, excessive and unthinking use of natural resources, difficult international relations, economic competition, and increasing environmental stress. Trends in global tourism have changed with changes in culture and our attitude to nature. Changes in both the profile and consumption patterns of tourists have called for the need to balance the use of natural and cultural assets with the need to adequately protect them. In this study, the Sarikum Nature Protection Area (SNPA) was selected as a case study because of its significance as a Turkish wetland area and the variety of different ecosystems coexisting within it. The study focussed on management strategies, but also provides a broader strategy for an area that currently has no management plan. Strengths and weaknesses, opportunities and threats (SWOT) analyses of the area were gathered and analyzed using R'WOT analysis (ranking + SWOT), a multi-criteria assessment method, in order to determine strategies, obtain the participation of interest groups, and assess their opinions and attitudes. The analysis showed the following: the rich biological diversity and the existence of endemic species were the reserve's most significant strength; the presence of natural areas in surrounding regions was the most significant opportunity; the shortage of infrastructure and lack of legal regulation of ecotourism was the most significant weakness; and the lack of a management plan was the most immediate threat.

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

    The majority of orthopaedic surgeons even currently agree that primary total arthroplasty in valgus knees with a deformity of more than ten degrees may prove challenging. The unique sets of bone and soft tissue abnormalities that must be addressed at the time of the operation make accurate axis restoration, component orientation and joint stability attainment a difficult task. Understanding the specific pathologic anatomic changes associated with the valgus knee is a prerequisite so as to select the proper surgical method, to optimize component position and restore soft-tissue balance. The purpose of this article is to review the valgus knee anatomical variations, to assess the best pre-operative planning and to evaluate how to choose the grade of constraint of the implant. It will also be underlying the up-to-date main approaches and surgical techniques be proposed in the English literature both for bone cuts and soft tissue management of valgus knees. PMID:26191494

    Natural resource management agencies continue to be one of the heavy users of remote sensing data. From the earliest days of aerial photography, managers have depended upon broad area coverage in various levels of resolution for information needed to conserve and preserve the Earth's resource base. The USDA Forest Service is one agency that has been an active user of remote sensing data since the days when foresters began using aerial photographs to analyze timber crops. To this day, the use of data acquired by aerial reconnaissance is an important part of the tools used to gather information. Last year, in April of 2002, the Forest Service, Remote Sensing Applications Cener with headquarters in Salt Lake City, Utah, sponsored The Ninth Biennial Remote Sensing Applications Conference in San Diego, California. Presentations at that conference demonstrate that airborne reconnaissance techniques continue to be of importance to managers of our natural resources. This paper is an overview of papers presented at the conference with emphasis upon applications that either use or have the potential to use airborne reconnaissance in data collection. Primary areas of interest include data collection for natural resource management and for law enforcement purposes on public lands an other remote, inaccessible back country areas.

Its adoption aims to improve quality and access to health services through the use of information and communication technologies (ICT), the implementation of digital literacy programs and access to quality information to advance towards more informed, equitable, competitive and democratic societies. PAHO/WHO considers that in society, free and equal access to health information should be a fundamental right of individuals. Access to information, knowledge sharing and use of information and communication technology in the health sector continues to grow and is driving significant changes in the way people interact with health services and among themselves in social networks and through the use of mobile devices (mHealth). This hyper-connected society, or information society, brings new challenges and opportunities related to the use of massive data (Big Data) that forces us to rethink our relationship with reality and the traditional ways of managing health information.

    2015-12-28

    Aneurysmal bone cysts are benign bone tumors that usually present in childhood and early adulthood. They usually manifest as expansile osteolytic lesions with a varying potential to be locally aggressive. Since their first description in 1942, a variety of treatment methods has been proposed. Traditionally, these tumors were treated with open surgery. Either intralesional surgical procedures or en bloc excisions have been described. Furthermore, a variety of chemical or physical adjuvants has been utilized in order to reduce the risk for local recurrence after excision. Currently, there is a shift to more minimally invasive procedures in order to avoid the complications of open surgical excision. Good results have been reported during percutaneous surgery, or the use of embolization. Recently, sclerotherapy has emerged as a promising treatment, showing effective consolidation of the lesions and functional results that appear to be superior to the ones of open surgery. Lastly, non-invasive treatment, such as pharmaceutical intervention with denosumab or bisphosphonates has been reported to be effective in the management of the disease. Radiotherapy has also been shown to confer good local control, either alone or in conjunction to other treatment modalities, but is associated with serious adverse effects. Here, we review the current literature on the methods of treatment of aneurysmal bone cysts. The indication for each type of treatment along reported outcome of the intervention, as well as potential complications are systematically presented. Our review aims to increase awareness of the different treatment modalities and facilitate decision-making regarding each individual patient. PMID:26793296

    Anaplastic glioma (AG) is divided into three morphology-based groups (anaplastic astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma) as well as three molecular groups (glioma-CpG island methylation phenotype [G-CIMP] negative, G-CIMP positive non-1p19q codeleted tumors and G-CIMP positive codeleted tumors). The RTOG 9402 and EORTC 26951 trials established radiotherapy plus (procarbazine, lomustine, vincristine) chemotherapy as the standard of care in 1p/19q codeleted AG. Uni- or non-codeleted AG are currently best treated with radiotherapy only or alkylator-based chemotherapy only as determined by the NOA-04 trial. Maturation of NOA-04 and results of the currently accruing studies, CODEL (for codeleted AG) and CATNON (for uni or non-codeleted AG), will likely refine current up-front treatment recommendations for AG.

    Autosomal dominant polycystic kidney disease (ADPKD), the most frequent cause of genetic renal disease affecting approximately 4 to 7 million individuals worldwide and accounting for 7%-15% of patients on renal replacement therapy, is a systemic disorder mainly involving the kidney but cysts can also occur in other organs such as the liver, pancreas, arachnoid membrane and seminal vesicles. Though computed tomography and magnetic resonance imaging (MRI) were similar in evaluating 81% of cystic lesions of the kidney, MRI may depict septa, wall thickening or enhancement leading to upgrade in cyst classification that can affect management. A screening strategy for intracranial aneurysms would provide 1.0 additional year of life without neurological disability to a 20-year-old patient with ADPKD and reduce the financial impact on society of the disease. Current treatment strategies include reducing: cyclic adenosine monophosphate levels, cell proliferation and fluid secretion. Several randomised clinical trials (RCT) including mammalian target of rapamycin inhibitors, somatostatin analogues and a vasopressin V2 receptor antagonist have been performed to study the effect of diverse drugs on growth of renal and hepatic cysts, and on deterioration of renal function. Prophylactic native nephrectomy is indicated in patients with a history of cyst infection or recurrent haemorrhage or to those in whom space must be made to implant the graft. The absence of large RCT on various aspects of the disease and its treatment leaves considerable uncertainty and ambiguity in many aspects of ADPKD patient care as it relates to end stage renal disease (ESRD). The outlook of patients with ADPKD is improving and is in fact much better than that for patients in ESRD due to other causes. This review highlights the need for well-structured RCTs as a first step towards trying newer interventions so as to develop updated clinical management guidelines. PMID:26380198

    Proper management of sickle cell anemia (SCA) begins with establishing the correct diagnosis early in life, ideally during the newborn period. The identification of affected infants by neonatal screening programs allows early initiation of prophylactic penicillin and pneumococcal immunizations, which help prevent overwhelming sepsis. Ongoing education of families promotes the early recognition of disease-released complications, which allows prompt and appropriate medical evaluation and therapeutic intervention. Periodic evaluation by trained specialists helps provide comprehensive care, including transcranial Doppler examinations to identify children at risk for primary stroke, plus assessments for other parenchymal organ damage as patients become teens and adults. Treatment approaches that previously highlighted acute vaso-occlusive events are now evolving to the concept of preventive therapy. Liberalized use of blood transfusions and early consideration of hydroxyurea treatment represent a new treatment paradigm for SCA management. PMID:23709685

    Polycythaemia vera (PV) is a chronic blood cancer; its clinical features are dominated by myeloproliferation (erythrocytosis, often leucocytosis and/or thrombocytosis) and a tendency for thrombosis and transformation to myelofibrosis or acute myeloid leukaemia. In the past 10 years the pathophysiology of this condition has been defined as JAK/STAT pathway activation, almost always due to mutations in JAK2 exons 12 or 14 (JAK2 V617F). In the same time period our understanding of the optimal management of PV has expanded, most recently culminating in the approval of JAK inhibitors for the treatment of PV patients who are resistant or intolerant to therapy with hydroxycarbamide. It has also been demonstrated that life expectancy for many patients with PV is not normal, nor is their quality of life. We critically explore these findings and discuss their impact. In addition, we highlight persisting gaps in our current management strategy; for example, what is the optimal first line cytoreductive therapy and, indeed, which patients need cytoreductive drugs.

    A dynamic and innovative approach to managing the blood-consuming nematode Haemonchus contortus in goats is critical to crack dependence on veterinary anthelmintics. H. contortus management strategies have been the subject of intense research for decades, and must be selected to create a tailored, individualized program for goat farms. Through the selection and combination of strategies from the Toolbox, an effective management program for H. contortus can be designed according to the unique conditions of each particular farm. This Toolbox investigates strategies including vaccines, bioactive forages, pasture/grazing management, behavioural management, natural immunity, FAMACHA, Refugia and strategic drenching, mineral/vitamin supplementation, copper Oxide Wire Particles (COWPs), breeding and selection/selecting resistant and resilient individuals, biological control and anthelmintic drugs. Barbervax(®), the ground-breaking Haemonchus vaccine developed and currently commercially available on a pilot scale for sheep, is prime for trialling in goats and would be an invaluable inclusion to this Toolbox. The specialised behaviours of goats, specifically their preferences to browse a variety of plants and accompanying physiological adaptations to the consumption of secondary compounds contained in browse, have long been unappreciated and thus overlooked as a valuable, sustainable strategy for Haemonchus management. These strategies are discussed in this review as to their value for inclusion into the 'Toolbox' currently, and the future implications of ongoing research for goat producers. Combining and manipulating strategies such as browsing behaviour, pasture management, bioactive forages and identifying and treating individual animals for haemonchosis, in addition to continuous evaluation of strategy effectiveness, is conducted using a model farm scenario.

    OBJECTIVE: An in-depth retrospective review of the multidisciplinary approach to the management of carcinoma of the breast was done. The author reviewed previous trials and treatment from the past to the present. The indications and contraindications of surgical procedures, radiation therapy, systemic chemotherapy, and hormonal therapy are discussed. SUMMARY BACKGROUND DATA: Carcinoma of the breast is one of the most common malignancies treated by the practicing general or oncologic surgeon. The disease is best treated using a multidisciplinary approach, combining the efforts of surgery, radiation therapy, and systemic treatments. Understanding the indications and contraindications for each of these modalities will provide the practicing surgeon the most up-to-date algorithms for the management of his/her patient. CONCLUSIONS: The author provides a comprehensive analysis of the multidisciplinary approach to the management of carcinoma of the breast. It emphasizes the results of previous trials and discusses future controversies and areas for study. Images Figure 1. Figure 3. Figure 4. PMID:8053734

    There is limited clinical evidence on the utility of the monitoring of Epstein-Barr virus (EBV) DNAemia in the pre-emptive management of post-transplant lymphoproliferative disease (PTLD) in solid organ transplant (SOT) recipients. We investigated current preventive measures against EBV-related PTLD through a web-based questionnaire sent to 669 SOT programmes in 35 European countries. This study was performed on behalf of the ESGICH study group from the European Society of Clinical Microbiology and Infectious Diseases. A total of 71 SOT programmes from 15 European countries participated in the study. EBV serostatus of the recipient is routinely obtained in 69/71 centres (97%) and 64 (90%) have access to EBV DNAemia assays. EBV monitoring is routinely used in 85.9% of the programmes and 77.4% reported performing pre-emptive treatment for patients with significant EBV DNAemia levels. Pre-emptive treatment for EBV DNAemia included reduction of immunosuppression in 50.9%, switch to mammalian target of rapamycin inhibitors in 30.9%, and use of rituximab in 14.5% of programmes. Imaging by whole-body 18-fluoro-deoxyglucose positron emission tomography (FDG-PET) is used in 60.9% of centres to rule out PTLD and complemented computer tomography is used in 50%. In 10.9% of centres, FDG-PET is included in the first-line diagnostic workup in patients with high-risk EBV DNAemia. Despite the lack of definitive evidence, EBV load measurements are frequently used in Europe to guide diagnostic workup and pre-emptive reduction of immunosuppression. We need prospective and controlled studies to define the impact of EBV monitoring in reducing the risk of PTLD in SOT recipients. PMID:25686696

    How can we effectively manage competing obligations from work and family without becoming overwhelmed? This question inspires the current study by examining control strategies that may facilitate better work-life balance, with a specific focus on the role of lowered aspirations and positive reappraisals, attitudes that underlie adaptive coping behaviors. Data from the Midlife in the United States Survey (MIDUS II) were used to explore the relationship between negative spillover, control strategies, and well-being among full-time working men and women (N = 2,091). In this nationally representative sample, findings indicate that while positive reappraisals function as a protective buffer, lowering aspirations exacerbate the relationship between work-family spillover and well-being, with moderating effects stronger among women. This study extends prior research tying work-life conflict to health and mental health, and suggests further investigation is needed to consider types of resources that may be effective coping strategies in balancing work and family.

    2010-07-01

    Sarcopenia, the progressive loss of muscle mass with age, is characterized by a deterioration of muscle quantity and quality leading to a gradual slowing of movement and a decline in strength and power. Sarcopenia is a highly significant public health problem. Since these age-related changes in skeletal muscle are largely attributed to various molecular mediators affecting fiber size, mitochondrial homeostatis, and apoptosis, the mechanisms responsible for these deleterious changes present numerous therapeutic targets for drug discovery. We and other researchers demonstrated that a disruption of Akt-mTOR and RhoA-SRF signaling but not Atrogin-1 or MuRF1 contributes to sarcopenia. In addition, sarcopenia seems to include a marked loss of fibers attributable to apoptosis. This review deals with molecular mechanisms of muscle atrophy and provides an update on current strategies (resistance training, myostatin inhibition, treatment with amino acids or testosterone, calorie restriction, etc) for counteracting this loss. Resistance training in combination with amino acid-containing nutrition would be the best candidate to attenuate, prevent, or ultimately reverse age-related muscle wasting and weakness.

    Alzheimer's disease (AD) currently presents one of the biggest healthcare issues in the developed countries. There is no effective treatment capable of slowing down disease progression. In recent years the main focus of research on novel pharmacotherapies was based on the amyloidogenic hypothesis of AD, which posits that the beta amyloid (Aβ) peptide is chiefly responsible for cognitive impairment and neuronal death. The goal of such treatments is (a) to reduce Aβ production through the inhibition of β and γ secretase enzymes and (b) to promote dissolution of existing cerebral Aβ plaques. However, this approach has proven to be only modestly effective. Recent studies suggest an alternative strategy centred on the inhibition of the downstream Aβ signalling, particularly at the synapse. Aβ oligomers may cause aberrant N-methyl-D-aspartate receptor (NMDAR) activation postsynaptically by forming complexes with the cell-surface prion protein (PrPC). PrPC is enriched at the neuronal postsynaptic density, where it interacts with Fyn tyrosine kinase. Fyn activation occurs when Aβ is bound to PrPC-Fyn complex. Fyn causes tyrosine phosphorylation of the NR2B subunit of metabotropic glutamate receptor 5 (mGluR5). Fyn kinase blockers masitinib and saracatinib have proven to be efficacious in treating AD symptoms in experimental mouse models of the disease. PMID:26881137

    In 1967, Starzl et al performed the first successful liver transplantation for a patient diagnosed with hepatoblastoma. In the following, liver transplantation was considered ideal for complete tumor resection and potential cure from primary hepatic malignancies. Several reports of liver transplantation for primary and metastatic liver cancer however showed disappointing results and the strategy was soon dismissed. In 1996, Mazzaferro et al introduced the Milan criteria, offering liver transplantation to patients diagnosed with limited hepatocellular carcinoma. Since then, liver transplantation for malignant disease is an ongoing subject of preclinical and clinical research. In this context, several aspects must be considered: (1) Given the shortage of deceased-donor organs, long-term overall and disease free survival should be comparable with results obtained in patients transplanted for non-malignant disease; (2) In this regard, living-donor liver transplantation may in selected patients help to solve the ethical dilemma of optimal individual patient treatment vs organ allocation justice; and (3) Ongoing research focusing on perioperative therapy and anti-proliferative immunosuppressive regimens may further reduce tumor recurrence in patients transplanted for malignant disease and thus improve overall survival. The present review gives an overview of current indications and future perspectives of liver transplantation for malignant disease. PMID:24833863

    Sprouts have gained popularity worldwide due to their nutritional values and health benefits. The fact that their consumption has been associated with numerous outbreaks of foodborne illness threatens the $250 million market that this industry has established in the United States. Therefore, sprout manufacturers have utilized the U.S. Food and Drug Administration recommended application of 20,000 ppm of calcium hypochlorite solution to seeds before germination as a preventative method. Concentrations of up to 200 ppm of chlorine wash are also commonly used on sprouts. However, chlorine-based treatment achieves on average only 1- to 3-log reductions in bacteria and is associated with negative health and environmental issues. The search for alternative strategies has been widespread, involving chemical, biological, physical, and hurdle processes that can achieve up to 7-log reductions in bacteria in some cases. The compilation here of the current scientific data related to these techniques is used to compare their efficacy for ensuring the microbial safety of sprouts and their practicality for commercial producers. Of specific importance for alternative seed and sprout treatments is maintaining the industry-accepted germination rate of 95% and the sensorial attributes of the final product. This review provides an evaluation of suggested decontamination technologies for seeds and sprouts before, during, and after germination and concludes that thermal inactivation of seeds and irradiation of sprouts are the most practical stand-alone microbial safety interventions for sprout production.

There is a growing interest in the clean up approaches that maintain soil quality after remediation treatments. This issue is of great importance in the U.S.A. where the EPA from 2009 is promoting innovative clean-up strategies (Green Remediation). Green remediation is defined as the practice of considering all environmental effects of remedy and incorporating options to maximize environmental benefit of cleanup actions . These remediation strategies restore contaminated sites to productive use with a great attention to the global environmental quality, including the preservation of soil functionality according to the following principles: use minimally invasive technologies; use passive energy technologies such as bioremediation and phytoremediation as primary remedies or finishing steps where possible and effective; minimize soil and habitat disturbance; minimize bioavailability of contaminants trough adequate contaminant source and plume control If we move from the current definition of remedial targets based on total concentrations, technologies with low impact on the environment can be utilized reducing the wrong choice to disposal soil in landfill destroying quickly a not renewable essential resource.

    The causes (medical, reproductive factors, health care delivery system, and socioeconomic factors) of maternal mortality in India and strategies for reducing maternal mortality are presented. Maternal mortality rates (MMR) are very high in Asia and Africa compared with Northern Europe's 4/100,000 live births. An Indian hospital study found the MMR to be 4.21/1000 live births. 50-98% of maternal deaths are caused by direct obstetric causes (hemorrhage, infection, and hypertensive disorders, ruptured uterus, hepatitis, and anemia). 50% of maternal deaths due to sepsis are related to illegal induced abortion. MMR in India has not declined significantly in the past 15 years. Age, primi and grande multiparity, unplanned pregnancy, and related illegal abortion are the reproductive causes. In 1985 WHO reported that 63-80% of maternal deaths due to direct obstetric causes and 88-98% of all maternal deaths could probably have been prevented with proper handling. In India, coordination between levels in the delivery system and fragmentation of care account for the poor quality of maternal health care. Mass illiteracy is another cause. Effective strategies for reducing the MMR are 1) to place a high priority on maternal and child health (MCH) services and integrate vertical programs (e.g., family planning) related to MCH; 2) to give attention to care during labor and delivery, which is the most critical period for complications; 3) to provide community-based delivery huts which can provide a clean and safe delivery place close to home, and maternity waiting rooms in hospitals for high risk mothers; 4) to improve the quality of MCH care at the rural community level (proper history taking, palpation, blood pressure and fetal heart screening, risk factor screening, and referral); 5) to improve quality of care at the primary health care level (emergency care and proper referral); 6) to include in the postpartum program MCH and family planning services; 7) to examine the

    Adaptive management is widely applied to natural resources management (Holling 1973; Walters and Holling 1990). Adaptive management can be generally defined as an iterative decision-making process that incorporates formulation of management objectives, actions designed to address these objectives, monitoring of results, and repeated adaptation of management until desired results are achieved (Brown and MacLeod 1996; Savory and Butterfield 1999). However, adaptive management is often criticized because very few projects ever complete more than one cycle, resulting in little adaptation and little knowledge gain (Lee 1999; Walters 2007). One significant criticism is that adaptive management is often used as a justification for undertaking actions with uncertain outcomes or as a surrogate for the development of specific, measurable indicators and monitoring programs (Lee 1999; Ruhl 2007).

    Safety management is a kind of system management, that is management by purposes. Taking "defence-in-depth" strategy, DDS - there can be defined four main aims and four method groups of risk management in transport: 1. minimizing transport accidents risk; 2. minimizing number of undesirable transport events (incidents, conflicts, collisions, accidents). Above purposes relate stages of safety management in transport. At each level of management should be elaborated methods, procedures and technologies of minimizing transport accidents risk. According to DDS any management system of transport safety should have a structure of multilevel chain protections which supervise main transport processes. About those problems in the paper.

    Biodiversity conservation has been criticized for undermining or ignoring social well-being. Currently efforts to mutually promote social justice, rural development, and biodiversity conservation, which have been contentious and yielded mixed results, continue to spread despite a general dearth of effective management strategies. We contend that social and economic concerns should be integral to conservation planning and propose that the scale of these phenomena is also critical. To evaluate the merit of this proposal, we adopted and expanded a conservation management strategy framework developed by Joel Heinen and examined how population density, economic disparity, and ethnic heterogeneity vary spatially surrounding 2 contrasting protected areas in East Africa: Kibale National Park in Uganda and Tarangire National Park in Tanzania. Analyses of demographic, wealth, and ethnicity data from regional censuses and household surveys conducted in 2009 and 2010 indicated that choice of scale (landscape or community) changed the management strategies recommended by the model. Therefore, "several small" people-park management strategies varying around a given protected area may be more appropriate than a "single large" people-park strategy applied across an entire protected area. Correspondingly, scale adjusted Heinen recommendations offered new strategies for effective conservation management within these human landscapes not incorporated in current in situ management plans.

    Taiwan is surrounded by oceans, so that the citizens' daily lives and the industrial activities in coast areas are exposed to and affected by strong winds and dust storms caused by the winter monsoon. Tree windbreaks present the functions of windproof, dust inhibition, damp-proof, and climate moderation. However, in recent years, the construction of roads, establishment industrial districts, development of recreation areas, building of wind turbines, and the cultivation of local citizens have greatly changed the width and integrity of tree windbreak belts, and in turn affected their functionality. Our study focus on tree windbreaks right next to the estuary of the Zhoushui River in Taiwan. Through environmental investigations, questionnaire surveys for local citizens, and vegetation sureys, the current functions of windbreaks and impacts of human disturbances on windbreaks will be evaluated. The conservation values and management strategies of tree windbreaks will be proposed after all.

    Thymoma is a rare neoplasm usually with an indolent growth pattern; however, local invasion and/or dissemination may occur. Surgery has been the standard of care for early stage disease with good to excellent cure rates anticipated. This neoplasm has been found to be relatively sensitive to cisplatinum-based chemotherapy as compared with most other epithelial tumors. Aggressive multimodality therapy therefore can result in long-term disease-free survival for patients presenting with locally advanced or even disseminated disease. This chapter outlines the current medical and surgical treatment options for thymoma. PMID:15229793

    The appropriate and timely evaluation and treatment of patients with severely elevated blood pressure is essential to avoid serious adverse outcomes. Most importantly, the distinction between a hypertensive emergency (crisis) and urgency needs to be made. A sudden elevation in systolic (SBP) and/or diastolic blood pressure (DBP) that is associated with acute end organ damage (cardiovascular, cerebrovascular, or renal) is defined as a hypertensive crisis or emergency. In contrast, acute elevation in SBP and/or DBP not associated with evidence of end organ damage is defined as hypertensive urgency. In patients with a hypertensive emergency, blood pressure control should be attained as expeditiously as possible with parenteral medications to prevent ongoing and potentially permanent end organ damage. In contrast, with hypertensive urgency, blood pressure control can be achieved with the use of oral medications within 24-48 hours. This paper reviews the management of hypertensive emergencies.

    Severe renal artery stenosis may cause renovascular hypertension; in case of bilateral narrowing or in a stenotic solitary kidney, renal insufficiency (ischemic kidney disease) or rarely pulmonary flush edema may occur. Renal artery stenosis may be treated by revascularization, using either percutaneous (balloon angioplasty, stenting) or less common open surgical procedures, both with excellent primary patency rates. However, randomized trials of renal artery angioplasty or stenting have failed to demonstrate a longer-term benefit with regard to blood pressure control and renal function over medical management alone (except for fibromuscular disease). Furthermore, endovascular procedures are associated with substantial risks. It has not yet been demonstrated that renal revascularization leads to a prolongation of event-free survival. Careful patient selection is essential to maximize the potential benefit. PMID:24217529

    Alzheimer's disease is a common neurological condition, appearing as early as age 40 but increasing dramatically in incidence over age 85. Different genetic factors are at play, modified by events over a lifetime. Clinical diagnosis is possible through careful history taking with a reliable informant and a minimum number of laboratory tests. A relatively predictable natural history can be observed, with progression through stages of cognitive loss, functional impairment and behavioural disinhibition or apathy. New medications such as donepezil offer hope for improving or stabilizing symptoms. Such treatment can be administered by primary care physicians with experience in the diagnosis and management of Alzheimer's disease. Disease stabilization, or even prevention, may be possible in the future. PMID:9347775

    Early and adequate resuscitation of patients with acute circulatory failure is important to restore the balance between oxygen needs and delivery. Haemodynamic management can globally be separated into three categories according to the VIP mnemonic - Ventilate, Infuse, Pump - which should be considered simultaneously in the patient with shock. Sufficient oxygen should be given early, and endotracheal intubation and mechanical ventilation performed without hesitation if there is any indication that oxygenation is inadequate. Fluids should be administered using the SOSD mnemonic - Salvage, Optimization, Stabilization, De-escalation. After initial liberal administration, ongoing requirements should be guided by repeated fluid challenges using a combination of balanced crystalloid solutions and colloid. Noradrenaline is the vasopressor of choice and should be started early. Dobutamine may be needed to improve myocardial contractility and cardiac output. Haemodynamic support should be personalized according to individual patient characteristics and global and regional parameters of haemodynamic and oxygenation status. PMID:27079763

    Objectives For some oncologic emergencies, surgical interventions are necessary for dissolution or temporary relieve. In the absence of guidelines, the most optimal method for decision making would be in a multidisciplinary cancer conference (MCC). In an acute setting, the opportunity for multidisciplinary discussion is often not available. In this study, the management and short term outcome of patients after surgical oncologic emergency consultation was analyzed. Method A prospective registration and follow up of adult patients with surgical oncologic emergencies between 01-11-2013 and 30-04-2014. The follow up period was 30 days. Results In total, 207 patients with surgical oncologic emergencies were included. Postoperative wound infections, malignant obstruction, and clinical deterioration due to progressive disease were the most frequent conditions for surgical oncologic emergency consultation. During the follow up period, 40% of patients underwent surgery. The median number of involved medical specialties was two. Only 30% of all patients were discussed in a MCC within 30 days after emergency consultation, and only 41% of the patients who underwent surgery were discussed in a MCC. For 79% of these patients, the surgical procedure was performed before the MCC. Mortality within 30 days was 13%. Conclusion In most cases, surgery occurred without discussing the patient in a MCC, regardless of the fact that multiple medical specialties were involved in the treatment process. There is a need for prognostic aids and acute oncology pathways with structural multidisciplinary management. These will provide in faster institution of the most appropriate personalized cancer care, and prevent unnecessary investigations or invasive therapy. PMID:25933135

    In addition to the current NASA manned programs, the maturation of Space Station and the introduction of the Space Exploration programs are anticipated to add substantially to the number and variety of data and documentation at NASA Johnson Space Center (JSC). This growth in the next decade has been estimated at five to ten fold compared to the current numbers. There will be an increased requirement for the tracking and currency of space program data and documents with National pressures to realize economic benefits from the research and technological developments of space programs. From a global perspective the demand for NASA's technical data and documentation is anticipated to increase at local, national, and international levels. The primary users will be government, industry, and academia. In our present national strategy, NASA's research and technology will assume a great role in the revitalization of the economy and gaining international competitiveness. Thus, greater demand will be placed on NASA's data and documentation resources. In this paper the strategies and procedures developed by DDMS, Inc., to accommodate the present and future information utilization needs are presented. The DDMS, Inc., strategies and procedures rely on understanding user requirements, library management issues, and technological applications for acquiring, searching, storing, and retrieving specific information accurately and quickly. The proposed approach responds to changing customer requirements and product deliveries. The unique features of the proposed strategy include: (1) To establish customer driven data and documentation management through an innovative and unique methods to identify needs and requirements. (2) To implement a structured process which responds to user needs, aimed at minimizing costs and maximizing services, resulting in increased productivity. (3) To provide a process of standardization of services and procedures. This standardization is the central

    Coronary artery bypass graft surgery remains one of the most widely performed surgical procedures in North America and aortocoronary saphenous vein grafts (SVG) are the most frequently used surgical conduits. SVG disease (SVGD) remains the leading cause of symptomatic coronary artery disease postcoronary artery bypass graft. When optimal medical therapy is ineffective, repeat surgery is associated with higher mortality combined with less favorable clinical and angiographic results, thus percutaneous revascularization on SVG is currently the standard of care for the revascularization of SVGD. Balloon angioplasty, bare metal stents, polytetrafluoroethylene-covered stents, and drug-eluting stents have been extensively investigated for SVG interventions. Multiple recent randomized trials and meta-analyses have confirmed the pathophysiologic and clinical differences between SVGD and coronary artery disease. Decisions such as patient selection, premedication, stent, and protection device characteristics should be carefully considered to achieve optimal procedural and clinical results. Acute coronary syndromes due to SVG involvement, chronic total occlusions, retrograde approaches, and SVG perforation management are newer fields requesting additional research. PMID:22777812

Cervical cancer is clinically staged, according to International Federation of Gynecology and Obstetrics guidelines, but, currently, there is increased use of cross sectional imaging modalities [computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-CT (PET-CT)] for the study of important prognostic factors like tumor size, parametrial invasion, endocervical extension, pelvic side wall or adjacent/distal organs involvement and lymph node status. Imaging indications also include cervical cancer follow-up, evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation. The preferred imaging method for local cervical cancer evaluation is MRI; CT is equally effective for evaluation of extrauterine spread of the disease. PET-CT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes. The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma.

  9. Current and emerging treatment strategies for Duchenne muscular dystrophy.

    Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy in childhood. It is caused by mutations of the DMD gene, leading to progressive muscle weakness, loss of independent ambulation by early teens, and premature death due to cardiorespiratory complications. The diagnosis can usually be made after careful review of the history and examination of affected boys presenting with developmental delay, proximal weakness, and elevated serum creatine kinase, plus confirmation by muscle biopsy or genetic testing. Precise characterization of the DMD mutation is important for genetic counseling and individualized treatment. Current standard of care includes the use of corticosteroids to prolong ambulation and to delay the onset of secondary complications. Early use of cardioprotective agents, noninvasive positive pressure ventilation, and other supportive strategies has improved the life expectancy and health-related quality of life for many young adults with DMD. New emerging treatment includes viral-mediated microdystrophin gene replacement, exon skipping to restore the reading frame, and nonsense suppression therapy to allow translation and production of a modified dystrophin protein. Other potential therapeutic targets involve upregulation of compensatory proteins, reduction of the inflammatory cascade, and enhancement of muscle regeneration. So far, data from DMD clinical trials have shown limited success in delaying disease progression; unforeseen obstacles included immune response against the generated mini-dystrophin, inconsistent evidence of dystrophin production in muscle biopsies, and failure to demonstrate a significant improvement in the primary outcome measure, as defined by the 6-minute walk test in some studies. The long-term safety and efficacy of emerging treatments will depend on the selection of appropriate clinical end points and sensitive biomarkers to detect meaningful changes in disease progression.

  11. Current management of ductal carcinoma in situ.

    1995-10-01

    Ductal carcinoma in situ represents a biologically and histologically heterogeneous group of lesions characterized by the proliferation of neoplastic epithelial cells confined to the ducts of the breast. Before screening mammography, ductal carcinoma in situ was considered uncommon; patients were usually diagnosed by a breast mass or bloody nipple discharge, and their treatment was mastectomy. Today it represents 20% to 30% of mammographically detected breast cancers and 10% to 15% of all diagnosed breast cancers in the United States. The invariable progression of this cancer to invasive breast cancer requiring mastectomy has been challenged, but because most patients have been treated with mastectomy, knowledge about ductal carcinoma in situ is limited and primarily based on retrospective data. Further insight will emerge from randomized prospective studies that are near completion. Currently available data indicate that breast-conserving treatments are valid alternatives to mastectomy for most patients with this disease. PMID:7483593

  12. Current management of urethral stricture disease

    2016-01-01

    Introduction: Broadly defined, urethral strictures are narrowing of the urethral lumen that is surrounded by corpus spongiosum, i.e., urethral meatus through the bulbar urethra. Urethral stenosis is narrowing of the posterior urethra, i.e., membranous urethra through bladder neck/prostate junction, which is not enveloped by corpus spongiosum. The disease has significant quality of life ramifications because many times younger patients are affected by this compared to many other urological diseases. Methods: A review of the scientific literature concerning urethral stricture, stenosis, treatment, and outcomes was performed using Medline and PubMed (U.S. National Library of Medicine and the National Institutes of Health). Abstracts from scientific meetings were included in this review. Results: There is level 3 evidence regarding the etiology and epidemiology of urethral strictures, stenoses, and pelvic fracture urethral injuries. Outcomes data from literature regarding intervention for urethral stricture are largely limited to level 3 evidence and expert opinion. There is a single level 1 study comparing urethral dilation and direct vision internal urethrotomy. Urethroplasty outcomes data are limited to level 3 case series. Conclusions: Progress is being made toward consistent terminology, and nomenclature which will, in turn, help to standardize treatment within the field of urology. Treatment for urethral stricture and stenosis remains inconsistent between reconstructive and nonreconstructive urologists due to varying treatment algorithms and approaches to disease management. Tissue engineering appears to be future for reconstructive urethral surgery with reports demonstrating feasibility in the use of different tissue substitutes and grafts. PMID:26941491

  16. Spatial strategies for managing visitor impacts in National Parks

    1999-01-01

    Resource and social impacts caused by recreationists and tourists have become a management concern in national parks and equivalent protected areas. The need to contain visitor impacts within acceptable limits has prompted park and protected area managers to implement a wide variety of strategies and actions, many of which are spatial in nature. This paper classifies and illustrates the basic spatial strategies for managing visitor impacts in parks and protected areas. A typology of four spatial strategies was proposed based on the recreation and park management literature. Spatial segregation is a common strategy for shielding sensitive resources from visitor impacts or for separating potentially conflicting types of use. Two forms of spatial segregation are zoning and closure. A spatial containment strategy is intended to minimize the aggregate extent of visitor impacts by confining use to limited designated or established Iocations. In contrast, a spatial dispersal strategy seeks to spread visitor use, reducing the frequency of use to levels that avoid or minimize permanent resource impacts or visitor crowding and conflict. Finally, a spatial configuration strategy minimizes impacting visitor behavior though the judicious spatial arrangement of facilities. These four spatial strategics can be implemented separately or in combination at varying spatial scales within a single park. A survey of national park managers provides an empirical example of the diversity of implemented spatial strategies in managing visitor impacts. Spatial segregation is frequently applied in the form of camping restrictions or closures to protect sensitive natural or cultural resources and to separate incompatible visitor activities. Spatial containment is the most widely applied strategy for minimizing the areal extent of resource impacts. Spatial dispersal is commonly applied to reduce visitor crowding or conflicts in popular destination areas but is less frequently applied or

  17. The current management of septic shock.

    2008-10-01

    This is a review of the management of septic shock that suggests an approach to treatment (ABCDEF: Airway, Breathing, Circulation, Drugs, Evaluate the source of sepsis, Fix the source of sepsis) for clinicians. The incidence of septic shock is increasing and mortality ranges from 30% to 70%. The commonest sources of infection are lung (25%), abdomen (25%), and other sources. Septic shock occurs because of highly complex interactions between the infecting microorganism(s) and the responses of the human host. The innate immune response is rapidly followed by the more specific adaptive immune response. Septic shock is characterized by alterations in the coagulant/anticoagulant balance such that there is a more pro-coagulant phenotype. Lung protective ventilation (which means the use of relatively low tidal volumes of 4 -6 mL/kg ideal body weight) is recommended for treatment of patients who have septic shock. Rivers early goal-directed therapy is recommended because it showed a significant increase in survival. Surviving Sepsis guidelines recommend resuscitation of septic shock with either crystalloid or colloid. Patients who have septic shock should be treated with intravenous broad-spectrum antibiotics as rapidly as possible and certainly within one hour. Activated protein C (APC) is a vitamin K dependent serine protease that is an anticoagulant and is also cytoprotective and anti-inflammatory. APC (24 mg/kg/hour infusion for 96 hours) decreased mortality (APC 25% vs placebo 31%, relative risk 0.81P=0.005) and improved organ dysfunction in patients at high risk of death (e.g. APACHE II >25 [APC 31% vs placebo 44%]). APC is not recommended to treat surgical patients who have one organ system dysfunction. In 2006, the European regulatory authority indicated that there must be another randomized placebo-controlled trial of APC to further establish efficacy as assessed by mortality reduction. Vasopressin is a key stress hormone in response to hypotension. The VASST

    Asthma is increasing in prevalence worldwide and results in significant use of healthcare resources. Although most patients with asthma can be adequately treated with inhaled corticosteroids, an important number of patients require additional therapy and an increasing number of options are available. A further minority of patients develop severe persistent asthma which remains difficult to manage despite current pharmacological therapies. This review discusses the various treatment options currently available for each stage of asthma severity, highlights some of the limitations of current management, and outlines directions which may improve the management of asthma in the future.

    Tapsall, John

    2002-02-01

    The incidence of gonorrhoea is again rising in developed countries and a high disease rate has been maintained in less developed regions for a number of years. The need not only for treatment of the individual but also for control of gonorrhoea at a community level has increased significantly following recognition of its role in the amplification of human immunodeficiency virus (HIV) transmission. A sustainable decrease in the incidence of gonorrhoea and other sexually transmitted diseases (STDs) requires an integrated approach combining improved prevention, better diagnosis and optimal treatment. Effective antibiotic treatment is an essential element of this approach. However, antibiotic treatment of gonorrhoea has been severely hampered by the development of antibiotic resistance in Neisseria gonorrhoeae, to the extent that many therapies are no longer effective. Those treatments that retain acceptable efficacy are often unaffordable where they are most needed. Penicillins and tetracyclines should no longer be used in gonococcal disease, there are limitations on the effectiveness of newer macrolides and spectinomycin and in many parts of the world quinolones have been withdrawn from schedules for the treatment of gonorrhoea. Of all the current agents used to treat all forms of gonococcal disease, only the third generation cephalosporins (most notably ceftriaxone) have retained their efficacy; however, decreased susceptibility to these antibiotics has also appeared. Continuing reliance on antibiotic treatment for controlling gonorrhoea in the absence of other necessary approaches will see a further deterioration in the situation. In these circumstances the possibility that gonorrhoea will be untreatable becomes more real. PMID:11829728

    Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment. PMID:23878534

  5. Current concepts of oxygen management in retinopathy of prematurity.

    PubMed

    Owen, Leah A; Hartnett, M Elizabeth

    2014-01-01

    Retinopathy of prematurity (ROP) is a potentially blinding disorder in premature infants. The underlying pathophysiology is incompletely understood, limiting the prevention and treatment of this devastating condition. Current therapies are directed toward management of aberrant neovascularization thought to result from retinal ischemia in the developing preterm retina. The molecular mediators important for development of retinal ischemia and subsequent neovascular pathology are not fully understood. However, oxygen has been shown to be a key mediator of disease and the oxygen environment for preterm infants has been extensively studied. Despite this, the optimal oxygen environment for preterm infants remains unclear and recent works seeking to clarify this relationship demonstrate somewhat disparate findings. These data further substantiate that ROP is a complex disease with multifactorial etiology including genetic and environmental factors. Therefore, while environmental factors such as oxygen are important to our understanding of the disease process and care of preterm infants, identification of the molecular mediators downstream of oxygen which are necessary for development of ROP pathology will be critical to improve prevention, diagnosis and treatment strategies.

    2013-01-01

    Diabetic nephropathy is the leading cause of end-stage renal disease in the United States. The progression of kidney disease in patients with diabetes can take many years, and interventions such as glycemic control, blood pressure control, and inhibition of the renin-angiotensin-aldosterone system have been shown to slow this progression. Despite the implementation of these strategies, the number of patients with diabetes that ultimately develop end-stage renal disease remains high. Recent investigation has focused on the optimization of renin-angiotensin-aldosterone system blockade in patients with diabetic nephropathy using combinations of drugs that target this pathway. Additional investigation has focused on the potential of novel therapies that either target various pathways upregulated by hyperglycemia or other targets believed to promote progression of diabetic nephropathy such as the endothelin system, inflammation and vitamin D receptors. This review article addresses some of the well-established principles regarding the progression and accepted management of diabetic nephropathy and includes current updates on the most recent clinical research trials exploring novel therapeutics in this field.

  7. Managing organizational change: strategies for the female health care supervisor.

    PubMed

    Davies, G

    1990-07-01

    In responding to resistance to change in the current health care organization, the new female supervisor can learn to support her staff in encountering and accepting these changes. The strategies and skills discussed above are characteristic of a supervisory style that may naturally occur for women, but also can be incorporated into the leadership style of men in health care management today. Health care leaders of tomorrow must work from an androgynous framework in which the behavior patterns and responses of each gender are learned and used appropriately by both men and women. Sargent suggests that the best managers are androgynous and that this is the inevitable wave of the future. Whether man or woman, a supervisor should learn, accept, and use methods that are characteristic of both sexes to be successful in managing people. Women and men must learn from each other's strengths and share these diverse skills. Given that women now outnumber men in health care management positions and organizations are changing to a more nurturing environment, the androgynous supervisor will be the successful leader of the future. Finally, women in health care supervisory positions have the potential to bring change where it is badly needed. Women in these roles often have a system wide view of health care policy issues that recognizes less federal commitment to social programs. Many women in health care positions believe that the issues of children, women, the elderly, the poor, and the homeless need focused attention. The growing number of women in health care supervisory and leadership roles is an important factor in changing national health policy for the benefit of these groups.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:10105044

    This article deepens understanding of the workplace experiences of racial minorities by investigating racial identity-based impression management (RIM) by Asian American journalists. Racial centrality, directly or indirectly, predicted the use of 4 RIM strategies (avoidance, enhancement, affiliation, and racial humor). Professional centrality also predicted strategy use, which was related to life satisfaction and perceived career success. By shedding light on proactive strategies that individuals use to influence colleagues' impressions of their racial identity, we contribute to research on diversity in organizations, impression management, and racial identity.
