Sepsis represents a major challenge in medicine. It begins as a systemic response to infection that can affect virtually any organ system, including the central and peripheral nervous systems. Akin to management of stroke, early recognition and treatment of sepsis are just as crucial to a successful outcome. Sepsis can precipitate myasthenic crisis and lead to encephalopathy and critical illness neuropathy. Stroke and traumatic brain injury can predispose a patient to develop sepsis, whereas Guillain-Barré syndrome is similarly not uncommon following infection. This review article will first describe the essential principles of sepsis recognition, pathophysiology, and management and will then briefly cover the neurologic aspects associated with sepsis. Vigilant awareness of the clinical features of sepsis and timeliness of intervention can help clinicians prevent progression of this disease to a multisystem organ failure, which can be difficult to reverse even after the original source of infection is under control.

It was a survey type of cross sectional study where the participants were from different teaching/referral hospital across the country and was done to gather information regarding current practice of management of neonatal sepsis among paediatricians and neonatologists and was conducted on the spot during a national conference of Bangladesh Perinatal Society in December 2013. Specialists in neonatology, paediatrics, and some other disciplines working in different institutes across the country were requested to respond. Out of 150 physicians, 92 (61.33%) were neonatologists. Physicians suspected early onset neonatal sepsis (EONS) when there is history suggestive of prolonged rupture of membrane (74.77%), prolonged labour (9.33%), chorioamnionitis (7.33%) and maternal fever (2%). Clinical sepsis is found commonly (53.33%) which is later proved by laboratory evidences such as Hb%, TC, DC PBF (peripheral blood film), C-reactive protein, chest X-ray etc. Injection Ampicillin and Gentamycin are still the first choice of antibiotics (61.3%). Preferred route was intravenous (95.3%). Antibiotics were given for 7-10 days by most of the physicians (48.77%). However there is lack of uniformity among the participants in regard to taking decision about antibiotics, the choice of first line and the subsequent options of antibiotics. So, neonatal sepsis is the most important cause of neonatal mortality in the community. Therefore a standard protocolized approach for diagnosis and management of Early Onset Neonatal Sepsis may prove critical which is currently not in practice uniformly.

Early onset neonatal sepsis is persistently associated with poor outcomes, and incites clinical practice based on the fear of missing a treatable infection in a timely fashion. Unnecessary exposure to antibiotics is also hazardous. Diagnostic dilemmas are discussed in this review, and suggestions offered for practical management while awaiting a more rapidly available 'gold standard' test; in an ideal world, this test would be 100% sensitive and 100% specific for the presence of organisms.

Objective To estimate the incidence of severe maternal sepsis due to group B Streptococcus (GBS) in the UK, and to investigate the associated outcomes for mother and infant. Design National case–control study. Setting All UK consultant-led maternity units. Participants 30 women with confirmed or suspected severe GBS sepsis, and 757 control women. Main outcome measures Disease incidence, additional maternal morbidity, critical care admission, length of stay, infant infection, mortality. Results The incidences of confirmed and presumed severe maternal GBS sepsis were 1.00 and 2.75 per 100 000 maternities, respectively, giving an overall incidence of 3.75 per 100 000. Compared with controls, severe GBS sepsis was associated with higher odds of additional maternal morbidity (OR 12.35, 95% CI 3.96 to 35.0), requiring level 2 (OR 39.3, 95% CI 16.0 to 99.3) or level 3 (OR 182, 95% CI 21.0 to 8701) care and longer hospital stay (median stay in cases and controls was 7 days (range 3–29 days) and 2 days (range 0–16 days), respectively, p<0.001). None of the women died. Severe maternal GBS sepsis was associated with higher odds of infant sepsis (OR 32.7, 95% CI 8.99 to 119.0); 79% of infants, however, did not develop sepsis. There were no associated stillbirths or neonatal deaths. Conclusions Severe maternal GBS sepsis is a rare occurrence in the UK. It is associated with adverse maternal and neonatal outcomes.

We examined United States Renal Data System registry records for Medicare-insured kidney transplant recipients in 2000–2011 to study the clinical and cost impacts of urinary tract infections (UTI), pneumonia, and sepsis in the first year post-transplant among a contemporary, national cohort. Infections were identified by billing diagnostic codes. Among 60,702 recipients, 45% experienced at least one study infection in the first year post-transplant, including UTI in 32%, pneumonia in 13%, and sepsis in 12%. Older recipient age, female sex, diabetic kidney failure, non-standard criteria organs, sirolimus-based immunosuppression and steroids at discharge were associated with increased risk of first-year infections. By time-varying, multivariate Cox regression, all study infections predicted increased first-year mortality, ranging from 41% (aHR 1.41, 95%CI 1.25–1.56) for UTI alone, 6-to-12-fold risk for pneumonia or sepsis alone, to 34-fold risk (aHR 34.38, 95%CI 30.35–38.95) for those with all three infections. Infections also significantly increased first-year costs, from $17,691 (standard error (SE) $591) marginal cost increase for UTI alone, to approximately $40,000–$50,000 (SE $1054–1238) for pneumonia or sepsis alone, to $134,773 (SE $1876) for those with UTI, pneumonia and sepsis. Clinical and economic impacts persisted in years 2–3 post-transplant. Early infections reflect important targets for management protocols to improve post-transplant outcomes and reduce costs of care.

Hospitalists are a critical link in providing evidence-based care for patients with sepsis across the disease spectrum, from early recognition to recovery. The past decade of sepsis research has led to significant findings that will change clinical practice for hospital medicine practitioners. Although the incidence of severe sepsis in the United States has continued to rise, in-hospital mortality has declined. Management of the spectrum of sepsis disorders is no longer restricted to the intensive care unit (ICU). This review article will provide an update in the management of sepsis for hospitalists based on recently published pivotal studies. The expanding evidence base in sepsis includes early goal-directed therapy/clinical endpoints/sepsis bundles, antibiotics and source control, volume resuscitation, ICU considerations (including the use of insulin and corticosteroids), mortality/complications, and the newly recognized condition of "sepsis survivorship".

Sepsis bundles represent key elements of care regarding the diagnosis and treatment of patients with septic shock and allow ones to convert complex guidelines into meaningful changes in behavior. Sepsis bundles endorsed the early goal-directed therapy (EGDT) and their implementation resulted in an improved outcome of septic shock patients. They induced more consistent and timely application of evidence-based care and reduced practice variability. These benefits mainly depend on the compliance with sepsis bundles, highlighting the importance of dedicated performance improvement initiatives, such as multifaceted educational programs. Nevertheless, the interest of early goal directed therapy in septic shock patients compared to usual care has recently been questioned, leading to an update of sepsis bundles in 2015. These new sepsis bundles may also exhibit, as the previous bundles, some limits and pitfalls and the effects of their implementation still needs to be evaluated. PMID:27713890

Sepsis affects practically all aspects of endothelial cell (EC) function and is thought to be the key factor in the progression from sepsis to organ failure. Endothelial functions affected by sepsis include vasoregulation, barrier function, inflammation, and hemostasis. These are among other mechanisms often mediated by glycocalyx shedding, such as abnormal nitric oxide metabolism, up-regulation of reactive oxygen species generation due to down-regulation of endothelial-associated antioxidant defenses, transcellular communication, proteases, exposure of adhesion molecules, and activation of tissue factor. This review covers current insight in EC-associated hemostatic responses to sepsis and the EC response to inflammation. The endothelial cell lining is highly heterogeneous between different organ systems and consequently also in its response to sepsis. In this context, we discuss the response of the endothelial cell lining to sepsis in the kidney, liver, and lung. Finally, we discuss evidence as to whether the EC response to sepsis is adaptive or maladaptive. This study is a result of an Acute Dialysis Quality Initiative XIV Sepsis Workgroup meeting held in Bogota, Columbia, between October 12 and 15, 2014.

Objective: Sepsis is defined as life-threatening organ dysfunction due to a dysregulated host response to infection. In this article, we reviewed the correlation between neutrophil dysfunction and sepsis. Data Sources: Articles published up to May 31, 2016, were selected from the PubMed databases, with the keywords of “neutrophil function”, “neutrophil dysfunction”, and “sepsis”. Study Selection: Articles were obtained and reviewed to analyze the neutrophil function in infection and neutrophil dysfunction in sepsis. Results: We emphasized the diagnosis of sepsis and its limitations. Pathophysiological mechanisms involve a generalized circulatory, immune, coagulopathic, and/or neuroendocrine response to infection. Many studies focused on neutrophil burst or cytokines. Complement activation, impairment of neutrophil migration, and endothelial lesions are involved in this progress. Alterations of cytokines, chemokines, and other mediators contribute to neutrophil dysfunction in sepsis. Conclusions: Sepsis represents a severe derangement of the immune response to infection, resulting in neutrophil dysfunction. Neutrophil dysfunction promotes sepsis and even leads to organ failure. Mechanism studies, clinical practice, and strategies to interrupt dysregulated neutrophil function in sepsis are desperately needed. PMID:27824008

Pediatric sepsis is distinct from adult sepsis in its definitions, clinical presentations, and management. Recognition of pediatric sepsis is complicated by the various pediatric-specific comorbidities that contribute to its mortality and the age- and development-specific vital sign and clinical parameters that obscure its recognition. This article outlines the clinical presentation and management of sepsis in neonates, infants, and children, and highlights some key populations who require specialized care.

Background: Sepsis is the leading cause of death among critically ill patients. Herein, we conducted a national survey to provide data on epidemiology and treatment of sepsis in the clinical practice in China, which has no detailed epidemiological data available on sepsis. Methods: This was a prospective cross-sectional survey from December 1, 2015 to January 31, 2016 in all provinces/municipalities of the mainland of China. The primary outcome of this study was the incidence of sepsis, and the secondary outcome was its etiology in China. Patients with sepsis admitted to the Intensive Care Units were included in this study. The demographic, physiological, bacteriological, and therapeutic data of these patients were recorded. The incidence of sepsis was estimated using the data from the sixth census in China, reported by the Chinese National Health and Family Planning Commission and the National Bureau of Statistics as the standard population. The independent risk factors for increased mortality from sepsis were calculated. Conclusions: This study indicated the incidence and outcome of sepsis in China. It also showed the most common etiology of different sites and types of infection, which could guide empiric antibiotic therapy. Moreover, it provided information on the independent risk factors for increased mortality due to sepsis. The findings provide evidence to guide clinical management and may help improve the outcome in septic patients.

Neonatal sepsis is the most common cause of neonatal deaths with high mortality despite treatment. Neonatal sepsis can be classified into two subtypes depending upon onset of symptoms. There are many factors that make neonates more susceptable to infection. Signs of sepsis in neonates are often non-specific and high degree of suspicion is needed for early diagnosis. Some laboratory parameters can be helpful for screening of neonates with neonatal sepsis, but none of it is specific and sensitive enough to be used singly. Diagnostic approach mostly focuses on history and review of non specific signs and symptoms. Antibiotic treatment is the mainstay of treatment and supportive care is equally important. The aim of this review is to give an overview of neonatal sepsis, including incidence, etiology, clinical picture, diagnostics and therapy.

Neonatal sepsis continues to be a common and significant health care burden, especially in very-low-birth-weight infants (VLBW <1500 g). Though intrapartum antibiotic prophylaxis has decreased the incidence of early-onset group B streptococcal infection dramatically, it still remains a major cause of neonatal sepsis. Moreover, some studies among VLBW preterm infants have shown an increase in early-onset sepsis caused by Escherichia coli. As the signs and symptoms of neonatal sepsis are nonspecific, early diagnosis and prompt treatment remains a challenge. There have been a myriad of studies on various diagnostic markers like hematological indices, acute phase reactants, C-reactive protein, procalcitonin, cytokines, and cell surface markers among others. Nonetheless, further research is needed to identify a biomarker with high diagnostic accuracy and validity. Some of the newer markers like inter α inhibitor proteins have shown promising results thereby potentially aiding in early detection of neonates with sepsis. In order to decrease the widespread, prolonged use of unnecessary antibiotics and improve the outcome of the infants with sepsis, reliable identification of sepsis at an earlier stage is paramount.

Dental sepsis or periapical abscess formation constitutes a large percentage of dental conditions that afflict horses. Dental sepsis occurs when the pulp chamber of the tooth is exposed to the oral cavity or external environment, allowing bacterial localization with resulting infection. Although acute, primary, septic pulpitis in horses is rare, dental sepsis often results from colonization of the pulp chamber with pathogenic bacteria secondary to maleruption or impaction of teeth with secondary alveolar bone lysis, primary fractures of the tooth, mandible, or maxilla, periodontal disease, or infundibular necrosis. The sequela to pulpal infection are extensions into the periradicular tissues and mandibular or maxillary periapical abscess formation.

Background Annually over 520,000 newborns die from neonatal sepsis, and 60,000 more from tetanus. Estimates of the effect of clean birth and postnatal care practices are required for evidence-based program planning. Objective To review the evidence for clean birth and postnatal care practices and estimate the effect on neonatal mortality from sepsis and tetanus for the Lives Saved Tool (LiST). Methods We conducted a systematic review of multiple databases. Data were abstracted into standard tables and assessed by GRADE criteria. Where appropriate, meta-analyses were undertaken. For interventions with low quality evidence but a strong GRADE recommendation, a Delphi process was conducted. Results Low quality evidence supports a reduction in all-cause neonatal mortality (19% (95% c.i. 1–34%)), cord infection (30% (95% c.i. 20–39%)) and neonatal tetanus (49% (95% c.i. 35–62%)) with birth attendant handwashing. Very low quality evidence supports a reduction in neonatal tetanus mortality with a clean birth surface (93% (95% c.i. 77-100%)) and no relationship between a clean perineum and tetanus. Low quality evidence supports a reduction of neonatal tetanus with facility birth (68% (95% c.i. 47-88%). No relationship was found between birth place and cord infections or sepsis mortality. For postnatal clean practices, all-cause mortality is reduced with chlorhexidine cord applications in the first 24 hours of life (34% (95% c.i. 5–54%, moderate quality evidence) and antimicrobial cord applications (63% (95% c.i. 41–86%, low quality evidence). One study of postnatal maternal handwashing reported reductions in all-cause mortality (44% (95% c.i. 18–62%)) and cord infection ((24% (95% c.i. 5-40%)). Given the low quality of evidence, a Delphi expert opinion process was undertaken. Thirty experts reached consensus regarding reduction of neonatal sepsis deaths by clean birth practices at home (15% (IQR 10–20)) or in a facility (27% IQR 24–36)), and by clean

OBJECTIVES--(a) To compare current vocational training in general practice with that ascertained by a survey in 1980; (b) to compare the training of trainees in formal training schemes with that of trainees arranging their own hospital and general practice posts. DESIGN--National questionnaire survey of United Kingdom and armed services trainees who were in a training practice on 1 April 1989. Questionnaires were distributed by course organisers. SETTING--Research project set up after an ad hoc meeting of trainees at the 1988 national trainee conference. SUBJECTS--2132 Of the 2281 trainees (93%) known to be in a training practice on 1 April 1989. RESULTS--1657 Trainees returned the questionnaires, representing 73% of all trainees known to be in a training practice on 1 April 1989. Between 1980 and 1989 there were significant improvements in the trainee year, and there was also evidence of improvements in general practice study release courses. There was no evidence of improvement in other aspects of training. General practice trainees spent an average of three years in junior hospital posts, which provided very little opportunity for study related to general practice. Training received during tenure of hospital posts differed significantly between trainees in formal schemes and those arranging their own hospital posts. During the trainee year training was almost the same for those in formal schemes and those arranging their own posts. Regions varied significantly in virtually all aspects of general practice training. CONCLUSIONS--The trainee year could be improved further by enforcing the guidelines of the Joint Committee on Postgraduate Training for General Practice. The poor training in junior hospital posts reflected the low priority that training is generally given during tenure of these posts. A higher proportion of general practice trainees should be attached to vocational training schemes. More hospital trainees could attend general practice study release
In daily practice acute arterial hypertension may occur during acute sepsis. No management guidelines concerning this issue figured in the latest sepsis campaign guidelines. Arterial hypertension occurring during sepsis could be an overlooked condition despite its potential haemodynamic harmful consequences. In this paper, a clinical study of acute hypertensive response related to sepsis is detailed. It shows that arterial hypertension, renal salt wasting and glomerular hyperfiltration can occur simultaneously during sepsis. Mechanisms and management options of sepsis-related arterial hypertensive response are also discussed. PMID:24855080

The United Nations General Assembly debate on antimicrobial resistance (AMR) recognizes the global significance of AMR. Much work needs to be done on technology capability and capacity to convert the strategic intent of the debate into operational plans and tangible outcomes. Enhancement of the biomedical science–clinician interface requires better exploitation of systems biology tools for in-laboratory and point of care methods that detect sepsis and characterize AMR. These need to link sepsis and AMR data with responsive, real-time surveillance. We propose an AMR sepsis register, similar in concept to a cancer registry, to aid coordination of AMR countermeasures.

Sepsis is a heterogeneous disease caused by an infection stimulus that triggers several complex local and systemic immuno-inflammatory reactions, which results in multiple organ dysfunction and significant morbidity and mortality. The diagnosis of sepsis is challenging because there is no gold standard for diagnosis. As a result, the clinical diagnosis of sepsis is ever changing to meet the clinical and research requirements. Moreover, although there are many novel biomarkers and screening tools for predicting the risk of sepsis, the diagnostic performance and effectiveness of these measures are less than satisfactory, and there is insufficient evidence to recommend clinical use of these new techniques. As a consequence, diagnostic criteria for sepsis need regular revision to cope with emerging evidence. This review aims to present the most updated information on diagnosis and early recognition of sepsis. Recommendations for clinical use of different diagnostic tools rely on the Grades of Recommendation Assessment, Development and Evaluation (GRADE) framework. Because most of the studies were observational and did not allow a reliable assessment of these tools, a two-step inference approach was employed. Future trials need to confirm or refute a particular index test and should directly explore relevant patient outcome parameters. PMID:27747021

Sepsis is a significant health problem in both critically ill children and adults. While the mortality rate from sepsis is much lower in children, sepsis is directly responsible for over 4,000 childhood deaths per year in the United States alone. At face value, this number suggests that more children die per year in the United States from sepsis as the primary cause than from cancer. Unfortunately, there are few studies on the epidemiology, pathophysiology, and management of sepsis in children. Moreover, extrapolation of adult data to critically ill children is probably not appropriate due to several key developmental differences in the host response to infection and response to therapy. Therefore, additional studies targeting sepsis in the pediatric population are urgently required.

If in clinical practice definitive diagnostic criteria had been established, after death sepsis is often difficult to diagnose, especially if a site of origin is not found or if no clinical data are available. This article will analyze the etiology of sepsis in a medical-legal service with emphasis on the differences in diagnosing it in clinical and forensic environments. A total of 78 cases of sepsis cases diagnosed or confirmed at the autopsy were selected. The etiological agent was determined either during the hospitalization or by postmortem bacteriology. A high prevalence of Gram-negative sepsis was found, especially multidrug-resistant micro-organisms. Most frequent etiological agents were Acinetobacter baumannii, Escherichia coli, Enterobacter, Enterococcus, Pseudomonas, and Klebsiella. Polymicrobial sepsis is much more frequent than in nonforensic cases. In legal medicine, the prevalence of Gram-negative sepsis is much higher than in nonforensic autopsies, and the point of origin is shifted toward the skin and the gastrointestinal system.

Fast and appropriate therapy is the cornerstone in the therapy of sepsis. However, the discrimination of sepsis from non-infectious causes of inflammation may be difficult. Biomarkers have been suggested to aid physicians in this decision. There is currently no biochemical technique available which alone allows a rapid and reliable discrimination between sepsis and non-infectious inflammation. Procalcitonin (PCT) is currently the most investigated biomarker for this purpose. C-reactive protein and interleukin 6 perform inferior to PCT in most studies and their value in diagnosing sepsis is not defined. All biomarkers including PCT are also released after various non-infectious inflammatory impacts. This shortcoming needs to be taken into account when biomarkers are used to aid the physician in the diagnosis of sepsis. Polymerase chain reaction (PCR) based pathogen detection may improve time to adequate therapy but cannot rule out the presence of infection when negative. PMID:24335467

Acute kindney injury (AKI) is a clinical syndrome which is generally defined as an abrupt decline in glomerular filtration rate, causing accumulation of nitrogenous products and rapid development of fluid, electrolyte and acid base disorders. In intensive care unit sepsis and septic shock are leading causes of AKI. Sepsis-induced AKI literally acts as a biologic indicator of clinical deterioration. AKI triggers variety of immune, inflammatory, metabolic and humoral patways; ultimately leading distant organ dysfunction and increases morbidity and mortality. Serial mesurements of creatinine and urine volume do not make it possible to diagnose AKI at early stages. Serum creatinine influenced by age, weight, hydration status and become apparent only when the kidneys have lost 50% of their function. For that reason we need new markers, and many biomarkers in the diagnosis of early AKI activity is assessed. Historically "Risk-Injury-Failure-Loss-Endstage" (RIFLE), "Acute Kidney Injury Netwok" (AKIN) and "The Kidney Disease/ Improving Global Outcomes" (KDIGO) classification systems are used for diagnosing easily in clinical practice and research and grading disease. Classifications including diagnostic criteria are formed for the identification of AKI. Neutrophil gelatinase associated lipocalin (NGAL), cystatin-C (Cys-C), kidney injury molecule-1 (KIM-1) and also "cell cycle arrest" molecules has been concerned for clinical use. In this review the pathophysiology of AKI, with the relationship of sepsis and the importance of early diagnosis of AKI is evaluated.

Sepsis is an unusual systemic reaction to what is sometimes an otherwise ordinary infection, and it probably represents a pattern of response by the immune system to injury. A hyper-inflammatory response is followed by an immunosuppressive phase during which multiple organ dysfunction is present and the patient is susceptible to nosocomial infection. Biomarkers to diagnose sepsis may allow early intervention which, although primarily supportive, can reduce the risk of death. Although lactate is currently the most commonly used biomarker to identify sepsis, other biomarkers may help to enhance lactate's effectiveness; these include markers of the hyper-inflammatory phase of sepsis, such as pro-inflammatory cytokines and chemokines; proteins such as C-reactive protein and procalcitonin which are synthesized in response to infection and inflammation; and markers of neutrophil and monocyte activation. Recently, markers of the immunosuppressive phase of sepsis, such as anti-inflammatory cytokines, and alterations of the cell surface markers of monocytes and lymphocytes have been examined. Combinations of pro- and anti-inflammatory biomarkers in a multi-marker panel may help identify patients who are developing severe sepsis before organ dysfunction has advanced too far. Combined with innovative approaches to treatment that target the immunosuppressive phase, these biomarkers may help to reduce the mortality rate associated with severe sepsis which, despite advances in supportive measures, remains high.

Summary Sepsis is a leading cause of mortality in critically ill patients. The pathophysiology of sepsis involves a highly complex and integrated response, including the activation of various cell types, inflammatory mediators, and the haemostatic system. Recent evidence suggests an emerging role of the microcirculation in sepsis, necessitating a shift in our locus away Irom the macrohaemodynamics to ill icrohaemodynanmics in a septic patient. This review article provides a brief overview of the microcirculation, its assessment techniques, and specific therapies to resuscitate the microhaemodynamics. PMID:20640135

Sepsis develops when the initial host response is unable to contain the primary infection, resulting in widespread inflammation and multiple organ dysfunction. The impairment of neutrophil migration into the infection site, also termed neutrophil paralysis, is a critical hallmark of sepsis, which is directly related to the severity of the disease. Although the precise mechanism of this phenomenon is not fully understood, there has been much advancement in the understanding of this field. In this review, we highlight the recent insights into the molecular mechanisms of neutrophil paralysis during sepsis.

Prehospital care providers are tasked with the delivery of time-sensitive care, and emergency medical services (EMS) systems must match patients to appropriate clinical resources. Modern systems are uniquely positioned to recognize and treat patients with sepsis. Interventions such as administration of intravenous fluid and transporting patients to the appropriate level of definitive care are linked to improved patient outcomes. As EMS systems refine their protocols for the recognition and stabilization of patients with suspected or presumed sepsis, EMS providers need to be educated about the spectrum of sepsis-related presentations and treatment strategies need to be standardized.

Vitamin D insufficiency and sepsis are both highly prevalent worldwide problems and this article reviews the emerging science that is defining the intersections of these conditions. The importance of vitamin D’s role in skeletal health has long been understood but recent evidence is beginning to highlight its role in the functioning of other physiologic systems of the body. Basic science data reveal its integral role in local immune responses to pathogens and the systemic inflammatory pathways of sepsis. Furthermore, clinical scientists have found associations with respiratory infections, critical illness and sepsis but the causal relationship and its clinical impact have yet to be clearly defined. The article ends with speculations on the connections between racial disparities and seasonal differences in sepsis and vitamin D insufficiency. PMID:22928065

Treatment manuals are currently the most common way treatments are disseminated to practicing clinicians, although little is known about the rates with which practicing therapists incorporate these manuals into their practice. In light of a widely acknowledged research-practice gap, understanding how often therapists are using manuals is important for shaping future dissemination efforts. This study collected data on rates of manual use among a national sample of mental health clinicians representative of those likely to be targeted in dissemination efforts (N = 756), as well as predictors of use. Results indicated that few clinicians (< 10%) routinely incorporated manuals into their practice, although most employed them to some degree. Predictors of manual use included greater openness to new treatments, younger age, and a cognitive-behavioral treatment orientation (ps < .05). Implications for future dissemination efforts are discussed.

Over the past decades, the incidence of sepsis and resultant neurologic sequelae has increased, both in industrialized and low- or middle-income countries, by approximately 5% per year. Up to 300 patients per 100 000 population per year are reported to suffer from sepsis, severe sepsis, and septic shock. Mortality is up to 30%, depending on the precision of diagnostic criteria. The increasing incidence of sepsis is partially explained by demographic changes in society, with aging, increasing numbers of immunocompromised patients, dissemination of multiresistant pathogens, and greater availability of supportive medical care in both industrialized and middle-income countries. This results in more septic patients being admitted to intensive care units. Septic encephalopathy is a manifestation especially of severe sepsis and septic shock where the neurologist plays a crucial role in diagnosis and management. It is well known that timely treatment of sepsis improves outcome and that septic encephalopathy may precede other signs and symptoms. Particularly in the elderly and immunocompromised patient, the brain may be the first organ to show signs of failure. The neurologist diagnosing early septic encephalopathy may therefore contribute to the optimal management of septic patients. The brain is not only an organ failing in sepsis (a "sepsis victim" - as with other organs), but it also overwhelmingly influences all inflammatory processes on a variety of pathophysiologic levels, thus contributing to the initiation and propagation of septic processes. Therefore, the best possible pathophysiologic understanding of septic encephalopathy is essential for its management, and the earliest possible therapy is crucial to prevent the evolution of septic encephalopathy, brain failure, and poor prognosis.

Sepsis results in widespread inflammatory responses altering homeostasis. Associated circulatory abnormalities (peripheral vasodilation, intravascular volume depletion, increased cellular metabolism, and myocardial depression) lead to an imbalance between oxygen delivery and demand, triggering end organ injury and failure. Fluid resuscitation is a key part of treatment, but there is little agreement on choice, amount, and end points for fluid resuscitation. Over the past few years, the safety of some fluid preparations has been questioned. Our paper highlights current concerns, reviews the science behind current practices, and aims to clarify some of the controversies surrounding fluid resuscitation in sepsis. PMID:25180196

Sepsis, severe sepsis and septic shock are syndromes. The incidence of sepsis is as high as 35% and with mortality rates in the intensive care unit from 27% to 54% in sepsis and septic shock, respectively. Many new treatments have been tested but only few have been implemented in clinical practise. The treatment of severe sepsis and septic shock is based on the Surviving Sepsis Campaign guidelines developed by an international expert panel. Early diagnosis, optimization of haemodynamics, rapid identification of focus and adequate antibiotic treatment are the most important strategies.

Sepsis-associated encephalopathy (SAE) is defined as a diffuse or multifocal cerebral dysfunction induced by the systemic response to the infection without clinical or laboratory evidence of direct brain infection. Its pathogenesis is multifactorial. SAE generally occurs early during severe sepsis and precedes multiple-organ failure. The most common clinical feature of SAE is the consciousness alteration which ranges from mildly reduced awareness to unresponsiveness and coma. Diagnosis of SAE is primarily clinical and depends on the exclusion of other possible causes of brain deterioration. Electroencephalography (EEG) is almost sensitive, but it is not specific for SAE. Computed Tomography (CT) head scan generally is negative in case of SAE, while Magnetic Resonance Imaging (MRI) can show brain abnormalities in case of SAE, but they are not specific for this condition. Somatosensitive Evoked Potentials (SEPs) are sensitive markers of developing cerebral dysfunction in sepsis. Cerebrospinal fluid (CBF) analysis is generally normal, a part an inconstant elevation of proteins concentration. S100B and NSE have been proposed like biomarkers for diagnosis of SAE, but the existing data are controversial. SAE is reversible even if survivors of severe sepsis have often long lasting or irreversible cognitive and behavioral sequel; however the presence of SAE can have a negative influence on survival. A specific therapy of SAE does not exist and the outcome depends on a prompt and appropriate treatment of sepsis as whole.

Objectives (1) Describe national patterns of chronic rhinosinusitis (CRS) care across academic and community practices. (2) Determine the prevalence of comorbid disorders in CRS patients, including nasal polyposis, allergic rhinitis, asthma, and cystic fibrosis. (3) Identify demographic, clinical, and practice type factors associated with endoscopic sinus surgery (ESS). Study Design Multisite cross-sectional study. Setting Otolaryngology's national research network CHEER (Creating Healthcare Excellence through Education and Research). Subjects and Methods A total of 17,828 adult patients with CRS were identified, of which 10,434 were seen at community practices (59%, n = 8 sites) and 7394 at academic practices (41%, n = 10 sites). Multivariate logistic regression was used to evaluate the association between demographic, practice type, and clinical factors and the odds of a patient undergoing ESS. Results The average age was 50.4 years; 59.5% of patients were female; and 88.3% were Caucasian. The prevalence of comorbid diseases was as follows: allergic rhinitis (35.1%), nasal polyposis (13.3%), asthma (4.4%), and cystic fibrosis (0.2%). In addition, 24.8% of patients at academic centers underwent ESS, as compared with 12.3% at community sites. In multivariate analyses, nasal polyposis (odds ratio [OR], 4.28), cystic fibrosis (OR, 2.42), and academic site type (OR, 1.86) were associated with ESS ( P < .001), while adjusting for other factors. Conclusions We describe practice patterns of CRS care, as well as demographic and clinical factors associated with ESS. This is the first study of practice patterns in CRS utilizing the CHEER network and may be used to guide future research.

Intervening in the event of a major crisis in France and abroad, the national gendarmerie intervention group carries out complex and specific operations in varied conditions and environments. Due to the multiplicity and dangerousness of the missions, adapted and integrated medical support is essential. In this context, nurses provide operational medical assistance as close as possible to the intervention. This nursing practice in an exceptional environment requires specific knowledge and intensive training.

The study investigated a relationship between National Board certification and perceived use of developmentally appropriate practices (DAP). A self-developed survey, the Early-childhood Teacher Inventory of Practices, was e-mailed to participants. Participants included 246 non-National Board-certified (non-NBCT) and 135 National Board-certified (NBCT) early childhood teachers. Descriptives were reported for age, years of teaching experience, grade level currently teaching, ethnicity, degree type, certification type, and degree level. Inferential statistics were used to understand the differences between perceived use of DAP. NBCTs scored significantly higher than non-NBCTs in three of the four target areas and on the total of the scale. Pearson product-moment corelations were used to determine a relationship between years of experience or level of education and NBCTs’ perceived use of DAP. Years of experience were significantly related, but level of education was not. The findings indicate that NBCT teachers perceive they incorporate more developmentally appropriate practices into their teaching than do non-NBCT teachers. PMID:23626399

Mitochondria are an essential part of the cellular infrastructure, being the primary site for high energy adenosine triphosphate (ATP) production through oxidative phosphorylation. Clearly, in severe systemic inflammatory states, like sepsis, cellular metabolism is usually altered and end organ dysfunction not only common but predictive of long term morbidity and mortality. Clearly, interest is mitochondrial function both as a target for intracellular injury and response to extrinsic stress have been a major focus of basic science and clinical research into the pathophysiology of acute illness. However, mitochondria have multiple metabolic and signaling functions that may be central in both the expression of sepsis and its ultimate outcome. In this review, the authors address five primary questions centered on the role of mitochondria in sepsis. This review should be used as both a summary source in placing mitochondrial physiology within the context of acute illness and as a focal point for addressing new research into diagnostic and treatment opportunities these insights provide.

This paper reports the findings of a research project designed to identify national issues impacting on the development of a mentoring framework for nurses in general practice in Australia. The project comprised the first phase of a three-phase study commissioned by the Australian Government Department of Health and Ageing to develop a contemporary, flexible and sustainable mentoring framework that enhances the capacity of nurses to contribute to general practice outcomes. Key stakeholders and influential informants from around Australia were brought together via a national teleconference to identify issues surrounding the development of such a framework. Outcomes focussed on major themes concerning choice, relationships, structures and resources. Here, we consider the issues and challenges identified in light of some contemporary case studies from outside the field of nursing in the hope of sparking new ideas and strategies. A case study from an Australian practice nurse is included. No research has been conducted on mentoring for nurses in general practice in Australia to date, highlighting an urgent need for new models and their evaluation.

Abortion, particularly later-term abortion, and neonaticide, selective non-treatment of newborns, are feasible management strategies for fetuses or newborns diagnosed with severe abnormalities. However, policy varies considerably among developed nations. This article examines abortion and neonatal policy in four nations: Israel, the US, the UK and Denmark. In Israel, late-term abortion is permitted while non-treatment of newborns is prohibited. In the US, on the other hand, later-term abortion is severely restricted, while treatment to newborns may be withdrawn. Policy in the UK and Denmark bridges some of these gaps with liberal abortion and neonatal policy. Disparate policy within and between nations creates practical and ethical difficulties. Practice diverges from policy as many practitioners find it difficult to adhere to official policy. Ethically, it is difficult to entirely justify perinatal policy in these nations. In each nation, there are elements of ethically sound policy, while other aspects cannot be defended. Ethical policy hinges on two underlying normative issues: the question of fetal/newborn status and the morality of killing and letting die. While each issue has been the subject of extensive debate, there are firm ethical norms that should serve as the basis for coherent and consistent perinatal policy. These include 1) a grant of full moral and legal status to the newborn but only partial moral and legal status to the late-term fetus 2) a general prohibition against feticide unless to save the life of the mother or prevent the birth of a fetus facing certain death or severe pain or suffering and 3) a general endorsement of neonaticide subject to a parent's assessment of the newborn's interest broadly defined to consider physical harm as well as social, psychological and or financial harm to related third parties. Policies in each of the nations surveyed diverging from these norms should be the subject of public discourse and, where possible

Despite remarkable advances in the knowledge of infection and human response to it, sepsis continues to be one of the most common challenges surgeons and critical care providers face. Surgeons confront the problem of infection every day, in treating established infections or reacting to a consequence of surgical intervention. Infections after surgery continue to be a problem despite massive efforts to prevent them. Patients rely on the surgeon's ability to recognize infection and treat it. Also, preventing nosocomial infection and antibiotic resistance is a primary responsibility. This article describes diagnostic and therapeutic measures for sepsis in the perioperative surgical patient.

The Fourth National Audit Project (NAP4) recommended airway training for trainee and trained anaesthetists. As the skills required for management of airway emergencies differ from routine skills and these events are rare, practical training is likely to require training workshops. In 2013, we surveyed all UK National Health Service hospitals to examine the current practices regarding airway training workshops. We received responses from 206 hospitals (62%) covering all regions. Regarding airway workshops, 16% provide none and 51% only for trainees. Of those providing workshops, more than half are run less than annually. Workshop content varies widely, with several Difficult Airway Society (DAS) guideline techniques not taught or only infrequently. Reported barriers to training include lack of time and departmental or individual interest. Workshop-based airway training is variable in provision, frequency and content, and is often not prioritised by departments or individual trainers. It could be useful if guidance on workshop organisation, frequency and content was considered nationally.

Sepsis is a life-threatening illness that occurs due to an abnormal host immune network which extends through the initial widespread and overwhelming inflammation, and culminates at the late stage of immunosupression. Recently, interest has been shifted toward therapies aimed at reversing the accompanying periods of immune suppression. Studies in experimental animals and critically ill patients have demonstrated that increased apoptosis of lymphoid organs and some parenchymal tissues contributes to this immune suppression, anergy and organ dysfunction. Immediate to the discoveries of the intracellular proteases, caspases for the induction of apoptosis and inflammation, and their striking roles in sepsis have been focused elaborately in a number of original and review articles. Here we revisited the different aspects of caspases in terms of apoptosis, pyroptosis, necroptosis and inflammation and focused their links in sepsis by reviewing several recent findings. In addition, we have documented striking perspectives which not only rewrite the pathophysiology, but also modernize our understanding for developing novel therapeutics against sepsis. PMID:25412304

Sepsis associated encephalopathy (SAE) is a common but poorly understood neurological complication of sepsis. It is characterized by diffuse brain dysfunction secondary to infection elsewhere in the body without overt CNS infection. The pathophysiology of SAE is complex and multifactorial including a number of intertwined mechanisms such as vascular damage, endothelial activation, breakdown of the blood brain barrier, altered brain signaling, brain inflammation, and apoptosis. Clinical presentation of SAE may range from mild symptoms such as malaise and concentration deficits to deep coma. The evaluation of cognitive dysfunction is made difficult by the absence of any specific investigations or biomarkers and the common use of sedation in critically ill patients. SAE thus remains diagnosis of exclusion which can only be made after ruling out other causes of altered mentation in a febrile, critically ill patient by appropriate investigations. In spite of high mortality rate, management of SAE is limited to treatment of the underlying infection and symptomatic treatment for delirium and seizures. It is important to be aware of this condition because SAE may present in early stages of sepsis, even before the diagnostic criteria for sepsis can be met. This review discusses the diagnostic approach to patients with SAE along with its epidemiology, pathophysiology, clinical presentation, and differential diagnosis.

Purpose of the review Although infection rates have modestly decreased in the neonatal intensive care unit (NICU) as a result of ongoing quality improvement measures, neonatal sepsis remains a frequent and devastating problem among hospitalized preterm neonates. Despite multiple attempts to address this unmet need, there have been minimal advances in clinical management, outcomes, and accuracy of diagnostic testing options over the last three decades. One strong contributor to a lack of medical progress is a variable case definition of disease. The inability to agree on a precise definition greatly reduces the likelihood of aligning findings from epidemiologists, clinicians, and researchers, which, in turn, severely hinders progress towards improving outcomes. Recent findings Pediatric consensus definitions for sepsis are not accurate in term infants and are not appropriate for preterm infants. In contrast to the defined multi-stage criteria for other devastating diseases encountered in the NICU (e.g., bronchopulmonary dysplasia), there is significant variability in the criteria used by investigators to substantiate the diagnosis of neonatal sepsis. Summary The lack of an accepted consensus definition for neonatal sepsis impedes our efforts towards improved diagnostic and prognostic options as well as accurate outcomes information for this vulnerable population.

Objectives Severe sepsis poses a major burden on the U.S. healthcare system. Previous epidemiologic studies have not differentiated community-acquired severe sepsis from healthcare-associated severe sepsis or hospital-acquired severe sepsis hospitalizations. We sought to compare and contrast community-acquired severe sepsis, healthcare-associated severe sepsis, and hospital-acquired severe sepsis hospitalizations in a national hospital sample. Setting United States Interventions None Measurements & Main Results Prevalence of community-acquired severe sepsis, healthcare-associated severe sepsis, and hospital-acquired severe sepsis, adjusted hospital mortality, length of hospitalization, length of stay in an ICU, and hospital costs. Among 3,355,753 hospital discharges, there were 307,491 with severe sepsis, including 193,081 (62.8%) community-acquired severe sepsis, 79,581 (25.9%) healthcare-associated severe sepsis, and 34,829 (11.3%) hospital-acquired severe sepsis. Hospital-acquired severe sepsis and healthcare-associated severe sepsis exhibited higher in-hospital mortality than community-acquired severe sepsis (hospital-acquired [19.2%] vs healthcare-associated [12.8%] vs community-acquired [8.6%]). Hospital-acquired severe sepsis had greater resource utilization than both healthcare-associated severe sepsis and community-acquired severe sepsis, with higher median length of hospital stay (hospital acquired [17 d] vs healthcare associated [7 d] vs community-acquired [6 d]), median length of ICU stay (hospital-acquired [8 d] vs healthcare-associated [3 d] vs community-acquired [3 d]), and median hospital costs (hospital-acquired [$38,369] vs healthcare-associated [$8,796] vs community-acquired [$7,024]). Conclusions In this series, severe sepsis hospitalizations included CA-SS (62.8%), HCA-SS (25.9%) and HA-SS (11.3%) cases. HA-SS was associated with both higher mortality and resource utilization than CA-SS and HCA-SS. PMID:26110490

This report concerns the Department of Energy's (Department) oversight of Sandia National Laboratories' (Sandia) salary administration practices for employees not covered by union agreements. Sandia is a management and operating (MandO) contractor responsible for research and development (RandD) relating to nuclear weapons and energy. Sandia's 1987 payroll was $319 million, $42 million for bargaining and $277 million for non-bargaining unit employees. For the period covered by the audit, Department policy required Headquarters monitoring and approval of the reasonableness of MandO contractor salary administration practices in cases where the annual non-bargaining payroll exceeded $75 million. The purpose of this audit was to determine whether Department oversight of Sandia employee compensation assured that contractor pay rates were consistent with Department policy.

Neonates are predisposed to infections during the perinatal period due to multiple exposures and a relatively compromised immune system. The burden of disease attributed to neonatal infections varies by geographic region and maternal and neonatal risk factors. Worldwide, it is estimated that more than 1.4 million neonatal deaths annually are the consequence of invasive infections. Risk factors for early-onset neonatal sepsis (EOS) include prematurity, immunologic immaturity, maternal Group B streptococcal colonization, prolonged rupture of membranes, and maternal intra-amniotic infection. Intrapartum antimicrobial prophylaxis administered to GBS-colonized women has reduced the burden of disease associated with early onset GBS invasive infections. Active surveillance has identified Gram-negative pathogens as an emerging etiology of early-onset invasive infections. Late-onset neonatal sepsis (LOS) attributable to Gram-positive organisms, including coagulase negative Staphylococci and Staphylococcus aureus, is associated with increased morbidity and mortality among premature infants. Invasive candidiasis is an emerging cause of late-onset sepsis, especially among infants who receive broad spectrum antimicrobial agents. Prophylactic fluconazole administration to very low birthweight (VLBW) neonates during the first 6 weeks of life reduces invasive candidiasis in neonatal intensive care units with high rates of fungal infection. Prevention of healthcare associated infections through antimicrobial stewardship, limited steroid use, early enteral feeding, limited use of invasive devices and standardization of catheter care practices, and meticulous hand hygiene are important and cost-effective strategies for reducing the burden of late-onset neonatal sepsis.

Myocardial dysfunction is one of the main predictors of poor outcome in septic patients, with mortality rates next to 70%. During the sepsis-induced myocardial dysfunction, both ventricles can dilate and diminish its ejection fraction, having less response to fluid resuscitation and catecholamines, but typically is assumed to be reversible within 7-10 days. In the last 30 years, It´s being subject of substantial research; however no explanation of its etiopathogenesis or effective treatment have been proved yet. The aim of this manuscript is to review on the most relevant aspects of the sepsis-induced myocardial dysfunction, discuss its clinical presentation, pathophysiology, etiopathogenesis, diagnostic tools and therapeutic strategies proposed in recent years.

Septic shock, the most severe complication of sepsis, accounts for approximately 10% of all admissions to intensive care. Our understanding of its complex pathophysiology remains incomplete but clearly involves stimulation of the immune system with subsequent inflammation and microvascular dysfunction. Cardiovascular dysfunction is pronounced and characterized by elements of hypovolaemic, cytotoxic, and distributive shock. In addition, significant myocardial depression is commonly observed. This septic cardiomyopathy is characterized by biventricular impairment of intrinsic myocardial contractility, with a subsequent reduction in left ventricular (LV) ejection fraction and LV stroke work index. This review details the myocardial dysfunction observed in adult septic shock, and discusses the underlying pathophysiology. The utility of using the regulatory protein troponin for the detection of myocardial dysfunction is also considered. Finally, options for the management of sepsis-induced LV hypokinesia are discussed, including the use of levosimendan.

Sepsis is a heterogeneous clinical syndrome that encompasses infections of many different types and severity. Not surprisingly, it has confounded most attempts to apply a single definition, which has also limited the ability to develop a set of reliable diagnostic criteria. It is perhaps best defined as the different clinical syndromes produced by an immune response to infection that causes harm to the body beyond that of the local effects of the infection.

Objectives To survey clinical practice and opinions of consultant surgeons and anaesthetists caring for children to inform the needs for training, commissioning and management of children's surgery in the UK. Design The National Confidential Enquiry into Patient Outcome and Death (NCEPOD) hosted an online survey to gather data on current clinical practice of UK consultant surgeons and anaesthetists caring for children. Setting The questionnaire was circulated to all hospitals and to Anaesthetic and Surgical Royal Colleges, and relevant specialist societies covering the UK and the Channel Islands and was mainly completed by consultants in District General Hospitals. Participants 555 surgeons and 1561 anaesthetists completed the questionnaire. Results 32.6% of surgeons and 43.5% of anaesthetists considered that there were deficiencies in their hospital's facilities that potentially compromised delivery of a safe children's surgical service. Almost 10% of all consultants considered that their postgraduate training was insufficient for current paediatric practice and 20% felt that recent Continued Professional Development failed to maintain paediatric expertise. 45.4% of surgeons and 39.2% of anaesthetists considered that the current specialty curriculum should have a larger paediatric component. Consultants in non-specialist paediatric centres were prepared to care for younger children admitted for surgery as emergencies than those admitted electively. Many of the surgeons and anaesthetists had <4 h/week in paediatric practice. Only 55.3% of surgeons and 42.8% of anaesthetists participated in any form of regular multidisciplinary review of children undergoing surgery. Conclusions There are significant obstacles to consultant surgeons and anaesthetists providing a competent surgical service for children. Postgraduate curricula must meet the needs of trainees who will be expected to include children in their caseload as consultants. Trusts must ensure appropriate

Severe sepsis is a major cause of morbidity and mortality in the UK. This article describes the collaborative development and implementation of an interactive online learning package to understand the key role nurses have in recognising and then starting to apply the Sepsis Six care bundle in clinical practice. The e-learning package, developed in a UK teaching hospital, uses a case study approach to address the knowledge that is required to be able to recognise sepsis, to understand the processes that occur and the ongoing care and treatment required. The package is relevant to final-year student nurses, newly registered nurses in preceptorship and other health professionals involved in assessing and treating patients who may be developing sepsis.

Data on sepsis prevalence on the general wards is lacking on the UK and in the developed world. We conducted a multicentre, prospective, observational study of the prevalence of patients with sepsis or severe sepsis on the general wards and Emergency Departments (ED) in Wales. During the 24-hour study period all patients with NEWS≥3 were screened for presence of 2 or more SIRS criteria. To be eligible for inclusion, patients had to have a high clinical suspicion of an infection, together with a systemic inflammatory response (sepsis) and evidence of acute organ dysfunction and/or shock (severe sepsis). There were 5317 in-patients in the 24-hour study period. Data were returned on 1198 digital data collection forms on patients with NEWS≥3 of which 87 were removed, leaving 1111 for analysis. 146 patients had sepsis and 144 patients had severe sepsis. Combined prevalence of sepsis and severe sepsis was 5.5% amongst all in-patients. Patients with sepsis had significantly higher NEWS scores (3 IQR 3–4 for non-sepsis and 4 IQR 3–6 for sepsis patients, respectively). Common organ dysfunctions in severe sepsis were hypoxia (47%), hypoperfusion (40%) and acute kidney injury (25%). Mortality at 90 days was 31% with a median (IQR) hospital free stay of 78 (36–85) days. Screening for sepsis, referral to Critical Care and completion of Sepsis 6 bundle was low: 26%, 16% and 12% in the sepsis group. Multivariable logistic regression analysis identified higher National Early Warning Score, diabetes, COPD, heart failure, malignancy and current or previous smoking habits as independent variables suggesting the diagnosis of sepsis. We observed that sepsis is more prevalent in the general ward and ED than previously suggested before and that screening and effective treatment for sepsis and severe sepsis is far from being operationalized in this environment, leading to high 90 days mortality.

The Surviving Sepsis Campaign (SSC) guidelines have outlined an early goal directed therapy (EGDT) which demonstrates a standardized approach to ensure prompt and effective management of sepsis. Having said that, there are barriers associated with the application of evidence-based practice, which often lead to an overall poorer adherence to guidelines. Considering the global burden of disease, data from low- to middle-income countries is scarce. Asia is the largest continent but most Asian countries do not have a well-developed healthcare system and compliance rates to resuscitation and management bundles are as low as 7.6% and 3.5%, respectively. Intensive care units are not adequately equipped and financial concerns limit implementation of expensive treatment strategies. Healthcare policy-makers should be notified in order to alleviate financial restrictions and ensure delivery of standard care to septic patients.

Severe sepsis is almost invariably associated with systemic activation of coagulation. There is ample evidence that demonstrates a wide-ranging cross-talk between hemostasis and inflammation, which is probably implicated in the pathogenesis of organ dysfunction in patients with sepsis. Inflammation not only leads to initiation and propagation of coagulation activity, but coagulation also markedly influences inflammation. Molecular mechanisms that play a role in inflammation-induced effects on coagulation have been recognized in much detail. Pro-inflammatory cells and cyto- and chemokines can activate the coagulation system and downregulate crucial physiological anticoagulant mechanisms. Initiation of coagulation activation and consequent thrombin generation is caused by expression of tissue factor on activated monocytes and endothelial cells and is ineffectually offset by tissue factor pathway inhibitor. At the same time, endothelial-associated anticoagulant pathways, in particular the protein C system, is impaired by pro-inflammatory cytokines. Also, fibrin removal is severely obstructed by inactivation of the endogenous fibrinolytic system, mainly as a result of upregulation of its principal inhibitor, plasminogen activator inhibitor type 1 (PAI-1). Increased fibrin generation and impaired break down lead to deposition of (micro)vascular clots, which may contribute to tissue ischemia and ensuing organ dysfunction. The foundation of the management of coagulation in sepsis is the explicit and thorough treatment of the underlying disorder by antibiotic treatment and source control measures. Adjunctive strategies focused at the impairment of coagulation, including anticoagulants and restoration of physiological anticoagulant mechanisms, may supposedly be indicated and have been found advantageous in experimental and initial clinical trials.

Early recognition of sepsis and septic shock in children relies on obtaining an attentive clinical history, accurate vital signs, and a physical examination focused on mental status, work of breathing, and circulatory status. Laboratory tests may support the diagnosis but are not reliable in isolation. The goal of septic shock management is reversal of tissue hypoperfusion. The therapeutic end point is shock reversal. Mortality is significantly better among children when managed appropriately. Every physician who cares for children must strive to have a high level of suspicion and keen clinical acumen for recognizing the rare but potentially seriously ill child.

Sepsis is recognized by the presence of physiologic and laboratory changes that reflect the inflammatory response to infection on cellular and systemic levels. Comorbid conditions, such as cirrhosis, end-stage renal disease, and obesity, alter patients' susceptibility to infection and their response to it once present. Baseline changes in vital signs and chronic medications often mask clues to the severity of illness. The physiologic, hematologic, and biochemical adjustments that accompany pregnancy and the puerperium introduce similar challenges. Emergency providers must remain vigilant for subtle alterations in the expected baseline for these conditions to arrive at appropriate management decisions.

Despite the progress made in the clinical management of sepsis, sepsis morbidity and mortality rates remain high. The inflammatory pathogenesis and organ injury leading to death from sepsis are not fully understood for vital organs, especially the liver. Only recently has the role of the liver in sepsis begun to be revealed. Pre-existing liver dysfunction is a risk factor for the progression of infection to sepsis. Liver dysfunction after sepsis is an independent risk factor for multiple organ dysfunction and sepsis-induced death. The liver works as a lymphoid organ in response to sepsis. Acting as a double-edged sword in sepsis, the liver-mediated immune response is responsible for clearing bacteria and toxins but also causes inflammation, immunosuppression, and organ damage. Attenuating liver injury and restoring liver function lowers morbidity and mortality rates in patients with sepsis. This review summarizes the central role of liver in the host immune response to sepsis and in clinical outcomes.

Sepsis is the most frequent cause of death in noncoronary intensive care units. In the past 10 years, progress has been made in the early identification of septic patients and their treatment. These improvements in support and therapy mean that mortality is gradually decreasing, however, the rate of death from sepsis remains unacceptably high. Immunotherapy is not currently part of the routine treatment of sepsis. Despite experimental successes, the administration of agents to block the effect of sepsis mediators failed to show evidence for improved outcome in a multitude of clinical trials. The following survey summarizes the current knowledge and results of clinical trials on the immunotherapy of sepsis and describes the limitations of our knowledge of the pathogenesis of sepsis. Administration of immunomodulatory drugs should be linked to the current immune status assessed by both clinical and molecular patterns. Thus, a careful daily review of the patient's immune status needs to be introduced into routine clinical practice giving the opportunity for effective and tailored use of immunomodulatory therapy.

Modern climate science assessments now have a history of nearly a quarter-century. This experience, together with important advances in relevant social sciences, has greatly improved our ability to communicate climate science effectively. As a result, the Third National Climate Assessment (NCA) was designed to be truly accessible and useful to all its intended audiences, while still being comprehensive and scientifically accurate. At a time when meeting the challenge of climate change is increasingly recognized as an urgent national and global priority, the NCA is proving to be valuable to decision-makers, the media, and the public. In producing this latest NCA, a communication perspective was an important part of the process from the beginning, rather than an afterthought as has often been the case with scientific reports. Lessons learned from past projects and science communications research fed into developing the communication strategy for the Third NCA. A team of editors and graphic designers worked closely with the authors on language, graphics, and photographs throughout the development of the report, Highlights document, and other products. A web design team helped bring the report to life online. There were also innovations in outreach, including a network of organizations intended to extend the reach of the assessment by engaging stakeholders throughout the process. Professional slide set development and media training were part of the preparation for the report's release. The launch of the NCA in May 2014 saw widespread and ongoing media coverage, continued references to the NCA by decision-makers, and praise from many quarters for its excellence in making complex science clear and accessible. This NCA is a professionally crafted report that exemplifies best practices in 21st century communications.

During sepsis, a complex network of cytokine, immune, and endothelial cell interactions occur and disturbances in the microcirculation cause organ dysfunction or even failure leading to high mortality in those patients. In this respect, numerous experimental and clinical studies indicate sex-specific differences in infectious diseases and sepsis. Female gender has been demonstrated to be protective under such conditions, whereas male gender may be deleterious due to a diminished cell-mediated immune response and cardiovascular functions. Male sex hormones, i.e., androgens, have been shown to be suppressive on cell-mediated immune responses. In contrast, female sex hormones exhibit protective effects which may contribute to the natural advantages of females under septic conditions. Thus, the hormonal status has to be considered when treating septic patients. Therefore, potential therapies could be derived from this knowledge. In this respect, administration of female sex hormones (estrogens and their precursors) may exert beneficial effects. Alternatively, blockade of male sex hormone receptors could result in maintained immune responses under adverse circulatory conditions. Finally, administration of agents that influence enzymes synthesizing female sex hormones which attenuate the levels of pro-inflammatory agents might exert salutary effects in septic patients. Prospective patient studies are required for transferring those important experimental findings into the clinical arena. PMID:24193307
Diminished availability of oxygen at the cellular level might account for organ dysfunction in sepsis. Although the classical forms of tissue hypoxia due to hypoxemia, anemia, or inadequate perfusion all might be important under some conditions, it seems increasingly likely that a fourth mechanism, namely cytopathic hypoxia, might play a role as well. The term cytopathic hypoxia is used to denote diminished production of adenosine triphosphate (ATP) despite normal (or even supranormal) PO2 values in the vicinity of mitochondria within cells. At least in theory, cytopathic hypoxia could be a consequence of several different (but mutually compatible) pathogenic mechanisms, including diminished delivery of a key substrate (e.g., pyruvate) into the mitochondrial tricarboxylic acid (TCA) cycle, inhibition of key mitochondrial enzymes involved in either the TCA cycle or the electron transport chain, activation of the enzyme, poly-(ADP)-ribosylpolymerase (PARP), or collapse of the protonic gradient across the inner mitochondrial membrane leading to uncoupling of oxidation (of NADH and FADH) from phosphorylation of ADP to form ATP. Tantalizing, but limited, data support the view that cytopathic hypoxia occurs in both animals and patients with sepsis or endotoxemia.

Introduction To assess changes in renal blood flow (RBF) in human and experimental sepsis, and to identify determinants of RBF. Method Using specific search terms we systematically interrogated two electronic reference libraries to identify experimental and human studies of sepsis and septic acute renal failure in which RBF was measured. In the retrieved studies, we assessed the influence of various factors on RBF during sepsis using statistical methods. Results We found no human studies in which RBF was measured with suitably accurate direct methods. Where it was measured in humans with sepsis, however, RBF was increased compared with normal. Of the 159 animal studies identified, 99 reported decreased RBF and 60 reported unchanged or increased RBF. The size of animal, technique of measurement, duration of measurement, method of induction of sepsis, and fluid administration had no effect on RBF. In contrast, on univariate analysis, state of consciousness of animals (P = 0.005), recovery after surgery (P < 0.001), haemodynamic pattern (hypodynamic or hyperdynamic state; P < 0.001) and cardiac output (P < 0.001) influenced RBF. However, multivariate analysis showed that only cardiac output remained an independent determinant of RBF (P < 0.001). Conclusion The impact of sepsis on RBF in humans is unknown. In experimental sepsis, RBF was reported to be decreased in two-thirds of studies (62 %) and unchanged or increased in one-third (38%). On univariate analysis, several factors not directly related to sepsis appear to influence RBF. However, multivariate analysis suggests that cardiac output has a dominant effect on RBF during sepsis, such that, in the presence of a decreased cardiac output, RBF is typically decreased, whereas in the presence of a preserved or increased cardiac output RBF is typically maintained or increased.

Since its original description in 1832, fluid resuscitation has become the cornerstone of early and aggressive treatment of severe sepsis and septic shock. However, questions remain about optimal fluid composition, dose, and rate of administration for critically ill patients. This article reviews pertinent physiology of the circulatory system, pathogenesis of septic shock, and phases of sepsis resuscitation, and then focuses on the type, rate, and amount of fluid administration for severe sepsis and septic shock, so providers can choose the right fluid, for the right patient, at the right time.

Performance appraisal (PA) is a key human resource activity in organizations. However, in this global economy, we know little about how societal cultures affect PA practices. In this study, we address this gap by focusing on 2 complementary issues: (a) the influence of societal (national) cultural practices on PA practices adopted by organizations and (b) the contribution of the level of congruence between societal cultural practices and the characteristics of organizational PA practices to absenteeism and turnover. The results, based on a large data set across multiple countries and over 2 time periods, support the hypothesized effects of societal (national) cultural practices on particular PA practices and the interactive effects of societal cultural practices and PA practices on absenteeism and turnover. We discuss theoretical and practical implications of our findings.

Sepsis often is characterized by an acute brain dysfunction, which is associated with increased morbidity and mortality. Its pathophysiology is highly complex, resulting from both inflammatory and noninflammatory processes, which may induce significant alterations in vulnerable areas of the brain. Important mechanisms include excessive microglial activation, impaired cerebral perfusion, blood–brain-barrier dysfunction, and altered neurotransmission. Systemic insults, such as prolonged inflammation, severe hypoxemia, and persistent hyperglycemia also may contribute to aggravate sepsis-induced brain dysfunction or injury. The diagnosis of brain dysfunction in sepsis relies essentially on neurological examination and neurological tests, such as EEG and neuroimaging. A brain MRI should be considered in case of persistent brain dysfunction after control of sepsis and exclusion of major confounding factors. Recent MRI studies suggest that septic shock can be associated with acute cerebrovascular lesions and white matter abnormalities. Currently, the management of brain dysfunction mainly consists of control of sepsis and prevention of all aggravating factors, including metabolic disturbances, drug overdoses, anticholinergic medications, withdrawal syndromes, and Wernicke’s encephalopathy. Modulation of microglial activation, prevention of blood–brain-barrier alterations, and use of antioxidants represent relevant therapeutic targets that may impact significantly on neurologic outcomes. In the future, investigations in patients with sepsis should be undertaken to reduce the duration of brain dysfunction and to study the impact of this reduction on important health outcomes, including functional and cognitive status in survivors.

Neonatal sepsis is a major cause of morbidity and mortality and its signs and symptoms are nonspecific, which makes the diagnosis difficult. The routinely used laboratory tests are not effective methods of analysis, as they are extremely nonspecific and often cause inappropriate use of antibiotics. Sepsis is the result of an infection associated with a systemic inflammatory response with production and release of a wide range of inflammatory mediators. Cytokines are potent inflammatory mediators and their serum levels are increased during infections, so changes from other inflammatory effector molecules may occur. Although proinflammatory and anti-inflammatory cytokines have been identified as probable markers of neonatal infection, in order to characterize the inflammatory response during sepsis, it is necessary to analyze a panel of cytokines and not only the measurement of individual cytokines. Measurements of inflammatory mediators bring new options for diagnosing and following up neonatal sepsis, thus enabling early treatment and, as a result, increased neonatal survival. By taking into account the magnitude of neonatal sepsis, the aim of this review is to address the role of cytokines in the pathogenesis of neonatal sepsis and its value as a diagnostic criterion.

Severe sepsis may be underrecognized in older adults. Therefore, the purpose of this article is to review special considerations related to early detection of severe sepsis in older adults. Normal organ changes attributed to aging may delay early detection of sepsis at the time when interventions have the greatest potential to improve patient outcomes. Systems are reviewed for changes. For example, the cardiovascular system may have a limited or absent compensatory response to inflammation after an infectious insult, and the febrile response and recruitment of white blood cells may be blunted because of immunosenescence in aging. Three of the 4 hallmark responses (temperature, heart rate, and white blood cell count) to systemic inflammation may be diminished in older adults as compared with younger adults. It is important to consider that older adults may not always manifest the typical systemic inflammatory response syndrome. Atypical signs such as confusion, decreased appetite, and unsteady gait may occur before sepsis related organ failure. Systemic inflammatory response syndrome criteria and a comparison of organ failure criteria were reviewed. Mortality rates in sepsis and severe sepsis remain high and are often complicated by multiple organ failures. As the numbers of older adults increase, early identification and prompt treatment is crucial in improving patient outcomes.

The Second National School Social Work Survey in 2014 aimed to update knowledge of school social work practice by examining how practitioner characteristics, practice context, and practice choices have evolved since the last national survey in 2008. This second survey was also developed to assess how the new national school social work practice model created by the School Social Work Association of America aligns with early 21st century school social work practice realities. The second survey was conducted from February through April 2014 (3,769 total responses were collected) and represents the largest sample of American school social workers surveyed in two decades. Data from the Second National School Social Work Survey showed a field that still has not fully responded to calls to implement evidence-informed and data-driven practices. This article notes the need to better integrate pre- and postservice training in data-driven practices and provides recommendations for ways to overcome barriers that school social workers report facing.
Neonatal sepsis is a life-threatening emergency and any delay in treatment may cause death. Initial signs of neonatal sepsis are slight and nonspecific. Therefore, in suspected sepsis, two or three days empirical antibiotic therapy should begin immediately after cultures have been obtained without awaiting the results. Antibiotics should be reevaluated when the results of the cultures and susceptibility tests are available. If the cultures are negative and the clinical findings are well, antibiotics should be stopped. Because of the nonspecific nature of neonatal sepsis, especially in small preterm infants, physicians continue antibiotics once started. If a baby has pneumonia or what appears to be sepsis, antibiotics should not be stopped, although cultures are negative. The duration of therapy depends on the initial response to the appropriate antibiotics but should be 10 to 14 days in most infants with sepsis and minimal or absent focal infection. In infants who developed sepsis during the first week of life, empirical therapy must cover group B streptococci, Enterobacteriaceae (especially E. coli) and Listeria monocytogenes. Penicillin or ampicillin plus an aminoglycoside is usually effective against all these organisms. Initial empirical antibiotic therapy for infants who developed sepsis beyond the first days of life must cover the organisms associated with early-onset sepsis as well as hospital-acquired pathogens such as staphylococci, enterococci and Pseudomonas aeruginosa. Penicillin or ampicillin and an aminoglycoside combination may also be used in the initial therapy of late-onset sepsis as in cases with early-onset sepsis. In nosocomial infections, netilmicin or amikacin should be preferred. In cases showing increased risk of staphylococcal infection (e.g. presence of vascular catheter) or Pseudomonas infection (e.g. presence of typical skin lesions), antistaphylococcal or anti-Pseudomonas agents may be preferred in the initial empirical therapy.

Sepsis is a common source of morbidity and mortality among critically ill patients, and targeting measures to promote early recognition and treatment of sepsis is at the forefront of many critical care initiatives. Starting formally in 1992, with the publication of the definitions of sepsis, continuous monitoring of several common physiologic parameters, including electrocardiogram, blood pressure, and oxygen saturation, have been advocated as important in the early identification and treatment of patients with sepsis. The descriptive study detailed in this article was conducted to assess the perceptions and clinical continuous physiologic monitoring practices of experienced critical care clinicians with regard to their use of common physiologic monitoring parameters in the care of patients with sepsis. A convenience sample of 100 physicians and 517 nurses completed a 20-item survey assessing perceptions and clinical monitoring practices related to the care of patients with sepsis. Results indicated that the basic parameters of electrocardiogram, invasive blood pressure, pulmonary arterial catheter monitoring, and oxygen saturation all have value in the recognition and treatment of patients with sepsis. The majority of clinicians used these parameters routinely and felt they were necessary for patient care. These results indicate that clinical practice is in concordance with current practice recommendations.

Sepsis-associated encephalopathy (SAE) is a diffuse brain dysfunction that occurs secondary to infection in the body without overt CNS infection. SAE is frequently encountered in critically ill patients in intensive care units, and in up to 70% of patients with severe systemic infection. The severity of SAE can range from mild delirium to deep coma. Seizures and myoclonus are infrequent and cranial nerves are almost always spared, but most severe cases have an associated critical illness neuromyopathy. Development of SAE probably involves a number of mechanisms that are not mutually exclusive and vary from patient to patient. Substantial neurological and psychological morbidities often occur in survivors. Mortality is almost always due to multiorgan failure rather than neurological complications, and is almost 70% in patients with severe SAE. Further research into the pathophysiology, management and prevention of SAE is needed. This Review discusses the epidemiology and clinical presentation of SAE. Recent evidence for SAE pathophysiology is outlined and a diagnostic approach to patients with this syndrome is presented. Lastly, prognosis and management of SAE is discussed.

Nearly 100 years ago, antimicrobial peptides (AMPs) were identified as an important part of innate immunity. They exist in species from bacteria to mammals and can be isolated in body fluids and on surfaces constitutively or induced by inflammation. Defensins have anti-bacterial effects against Gram-positive and Gram-negative bacteria as well as anti-viral and anti-yeast effects. Human neutrophil peptides (HNP) 1–3 and human beta-defensins (HBDs) 1–3 are some of the most important defensins in humans. Recent studies have demonstrated higher levels of HNP 1–3 and HBD-2 in sepsis. The bactericidal/permeability-increasing protein (BPI) attenuates local inflammatory response and decreases systemic toxicity of endotoxins. Moreover, BPI might reflect the severity of organ dysfunction in sepsis. Elevated plasma lactoferrin is detected in patients with organ failure. HNP 1–3, lactoferrin, BPI, and heparin-binding protein are increased in sepsis. Human lactoferrin peptide 1–11 (hLF 1–11) possesses antimicrobial activity and modulates inflammation. The recombinant form of lactoferrin [talactoferrin alpha (TLF)] has been shown to decrease mortality in critically ill patients. A phase II/III study with TLF in sepsis did not confirm this result. The growing number of multiresistant bacteria is an ongoing problem in sepsis therapy. Furthermore, antibiotics are known to promote the liberation of pro-inflammatory cell components and thus augment the severity of sepsis. Compared to antibiotics, AMPs kill bacteria but also neutralize pathogenic factors such as lipopolysaccharide. The obstacle to applying naturally occurring AMPs is their high nephro- and neurotoxicity. Therefore, the challenge is to develop peptides to treat septic patients effectively without causing harm. This overview focuses on natural and synthetic AMPs in human and experimental sepsis and their potential to provide significant improvements in the treatment of critically ill with severe infections

The disease burden of sepsis is a global issue. Most of the large-scale epidemiological investigations on sepsis have been carried out in developed countries. The population of 1.3 billion in mainland China accounts for approximately 1/5th of the whole world population. Thus, the knowledge of the incidence and mortality of sepsis in mainland China is vital before employing measures for its improvement. However, most of the epidemiological data of sepsis in mainland China was obtained from ICU settings, and thus lacks the population-based incidence and mortality of sepsis. In the present review, we summarized the limited literature encompassing the incidence, mortality, long-term outcome, and pathogens of sepsis in mainland China. Therefore, it might provide some valuable information regarding the sepsis disease burden and current issues in the management of sepsis in mainland China. PMID:27713882

The increased incidence of sepsis, a systemic response to infection that occurs in some patients, has stimulated interest in identifying infected patients who are at risk and intervening early. When this condition progresses to severe sepsis (characterized by organ dysfunction), mortality is high. Hospitals that have implemented recommendations of the Surviving Sepsis Campaign have seen a reduction in mortality rate for hospital-acquired severe sepsis. They may reduce this further by focusing on new approaches to diagnosing sepsis, especially at an early stage. Sepsis is a complicated syndrome with many physiological derangements and many emerging laboratory markers of sepsis have been proposed as adjuncts to clinical evaluation. The list includes cytokines, acute phase proteins, neutrophil activation markers, markers of abnormal coagulation and, recently, markers of suppression of both the innate and adaptive immune response. The perfect biomarker would accurately identify patients at risk of developing severe sepsis and then guide targeted therapy.

clinical practice. Greater understanding of the epidemiology of sepsis could improve care quality and outcomes.What is known about the topic? Sepsis is associated with high mortality rates and severe sepsis is the most common cause of death in intensive care units (ICU). The last published study of sepsis in Victoria (in 2005) showed a gradual rise in rates; since then, there is little information as to whether there has been any significant improvement in treatment outcomes.What does this paper add? This paper provides new information by analysing trends and variations in sepsis hospitalisations in Victoria by several demographic groups from 2004-05 to 2013-14.What are the implications for practitioners? Patients with severe sepsis consume approximately half the ICU resources. Reliable and recent data on the growth of this disease are important for prevention, allocation of resources and to track the effectiveness of care. A key area for intervention is promoting greater adherence to clinical guidelines.

The concept of systemic inflammatory response syndrome (SIRS) was introduced in 1992 to define and objectively diagnose sepsis. Over the last decade, the definition of sepsis has been used for inclusion criteria of multicenter trials to develop innovative therapies of sepsis. With the recent understanding of the pathogenetic mechanisms of sepsis, many drugs have been tested, but only two drugs (activated protein C and neutrophil-elastase inhibitor) have been approved for clinical use in sepsis or SIRS. Further understanding of basic pathophysiology of SIRS and sepsis holds promise to develop a new therapeutic strategy to improve survival of patients with SIRS and sepsis.

Galactosemia is one of the rare inborn errors of metabolism, which if detected early can be treated effectively. Galactosemic infants have a significant increased risk of developing sepsis. E. coli sepsis is a known entity, and also an important cause of early mortality in these children. But fungal sepsis in these patients is rarely reported. Here is a case of 45 day-old child who presented with fungal sepsis, which on investigation turned out to be galactosemia.

The incidence of sepsis caused by transfusion of bacterially contaminated blood components is similar to or less than that of transfusion-transmitted hepatitis C virus infection, yet significantly exceeds those currently estimated for transfusion-associated human immunodeficiency and hepatitis B viruses. Outcomes are serious and may be fatal. In addition, transfusion of sterile allogenic blood can have generalized immunosuppressive effects on recipients, resulting in increased susceptibility to postoperative infection. This review examines the frequency of occurrence of transfusion-associated sepsis, the organisms implicated, and potential sources of bacteria. Approaches to minimize the frequency of sepsis are discussed, including the benefits and disadvantages of altering the storage conditions for blood. In addition, the impact of high levels of bacteria on the gross characteristics of erythrocyte and platelet concentrates is described. The potentials and limitations of current tests for detecting bacteria in blood are also discussed. PMID:7923050

The pathophysiology of sepsis and its accompanying systemic inflammatory response syndrome (SIRS) and the events that lead to multiorgan failure and death are poorly understood. It is known that, in septic humans and rodents, the development of SIRS is associated with a loss of the redox balance, but SIRS can also develop in noninfectious states. In addition, a hyperinflammatory state develops, together with impaired innate immune functions of phagocytes, immunosuppression, and complement activation, collectively leading to septic shock and lethality. Here, we discuss recent insights into the signaling pathways in immune and phagocytic cells that underlie sepsis and SIRS and consider how these might be targeted for therapeutic interventions to reverse or attenuate pathways that lead to lethality during sepsis.

Copernicus is an European system created for Earth observation and monitoring. It consists of a set of Earth observation satellites and in-situ sensors that provide geo-information that are used, through a set of Copernicus services, for applications related to the environment and global security. The main services of the Copernicus programme address six thematic areas: land, marine, atmosphere, climate change, emergency management and security. In Germany, there is a national service team of Copernicus service coordinators, who are responsible for the national development of the Copernicus services and for providing user-specific information about the Copernicus processes. These coordinators represent the contact points for all the programmes and services concerning their respective Copernicus theme. To publish information about Copernicus, national conferences and workshops are organised. Many people are involved in planning the continuous process of bringing the information to public authorities, research institutes and commercial companies. The Federal Agency for Cartography and Geodesy (Bundesamt für Kartographie und Geodäsie, BKG) is one such organisation, and is mainly responsible for the national land monitoring service of Copernicus. To make use of the freely available data from the Copernicus programme, the Federal Agency for Cartography and Geodesy is currently developing new applications and projects in the field of remote sensing and land monitoring. These projects can be used by other public authorities as examples on how to use the Copernicus data and services for their individual demands and requirements. Copernicus data and services are currently not very commonly used in the daily routine of the national mapping agencies, but they will soon be.

Galactosemia is a treatable metabolic disorder caused by the deficiency of enzyme galactose-1-phosphate uridyl transferase (GALT) and inherited as an autosomal recessive trait. A case of neonate manifesting with recurrent Escherichia coli sepsis is presented here which turned out to be a classic galactosemia. No other common presenting features were observed in this infant except cataract on slit lamp examination. To the best of our knowledge, there is no case of galactosemia reported in literature which presented with recurrent neonatal sepsis without hepatomegaly, hyperbilirubinemia, bleeding disorder, vomiting, diarrhea, failure to thrive, hypoglycemia, coagulopathy, hemolysis or renal tubular acidosis.

Vasopressor and inotropes are beneficial in shock states. Norepinephrine is considered the first-line vasopressor for patients with sepsis-associated hypotension. Dobutamine is considered the first-line inotrope in sepsis, and should be considered for patients with evidence of myocardial dysfunction or ongoing signs of hypoperfusion. Vasopressor and inotrope therapy has complex effects that are often difficult to predict; emergency providers should consider the physiology and clinical trial data. It is essential to continually reevaluate the patient to determine if the selected treatment is having the intended result.

Sepsis and septic shock are major health conditions in the United States, with a high incidence and mortality. The Surviving Sepsis Campaign, which was formed in 2002, formulates guidelines for the management of severe sepsis and septic shock and has actually demonstrated a reduction in mortality with institution of "sepsis bundles." Despite this, some elements of the guidelines have been questioned, and recent data suggest that strict compliance with bundles and protocols may not be necessary. Still, prompt recognition and treatment of sepsis and septic shock remain of utmost importance.
Sepsis, the systemic inflammatory response to infection, causes high mortality in patients in non-coronary units of intensive care. The most important characteristic of sepsis is the interaction between two subjects, the macro and the microorganism, associated with the dysfunction of innate and adaptive immunity. Sepsis is understood more as a dynamic syndrome characterized by many phenomenona which are often antagonistic. The inflammation, characterizing sepsis, does not act as a primary physiological compensatory mechanism and rather oscillates between the phase of hyperinflammatory response and anergy or immunoparalysis. The elucidation of the pathogenesis of sepsis is linked to the understanding of immunopathogenetic mechanisms, which characterize the interaction between the macro and microorganisms.

Problem Annually affecting over 18 million people worldwide, sepsis is common, deadly, and costly. Despite significant effort by the Surviving Sepsis Campaign and other initiatives, sepsis remains underrecognized and undertreated. Approach Research indicates that educating providers may improve sepsis diagnosis and treatment; thus, the Stanford School of Medicine has developed a mobile-accessible, case-based, online game entitled Septris (http://med.stanford.edu/septris/). Septris, launched online worldwide in December 2011, takes an innovative approach to teaching early sepsis identification and evidence-based management. The free gaming platform leverages the massive expansion over the past decade of smartphones and the popularity of noneducational gaming. The authors sought to assess the game’s dissemination and its impact on learners’ sepsis-related knowledge, skills, and attitudes. In 2012, the authors trained Stanford pregraduate (clerkship) and postgraduate (resident) medical learners (n = 156) in sepsis diagnosis and evidence-based practices via 20 minutes of self-directed game play with Septris. The authors administered pre- and posttests. Outcomes By October 2014, Septris garnered over 61,000 visits worldwide. After playing Septris, both pre- and postgraduate groups improved their knowledge on written testing in recognizing and managing sepsis (P < .001). Retrospective self-reporting on their ability to identify and manage sepsis also improved (P < .001). Over 85% of learners reported that they would or would maybe recommend Septris. Next Steps Future evaluation of Septris should assess its effectiveness among different providers, resource settings, and cultures; generate information about how different learners make clinical decisions; and evaluate the correlation of game scores with sepsis knowledge.

In response to reports of increasing financial and administrative burdens on oncology practices and a lack of systematic information related to these issues, American Society of Clinical Oncology (ASCO) leadership started an effort to collect key practice-level data from all oncology practices in the United States. The result of the effort is the ASCO National Census of Oncology Practices (Census) launched in June 2012. The initial Census work involved compiling an inventory of oncology practices from existing lists of oncology physicians in the United States. A comprehensive, online data collection instrument was developed, which covered a number of areas, including practice characteristics (staffing configuration, organizational structure, patient mix and volume, types of services offered); organizational, staffing, and service changes over the past 12 months; and an assessment of the likelihood that the practice would experience organizational, staffing, and service changes in the next 12 months. More than 600 practices participated in the Census by providing information. In this article, we present preliminary highlights from the data gathered to date. We found that practice size was related to having experienced practice mergers, hiring additional staff, and increasing staff pay in the past 12 months, that geographic location was related to having experienced hiring additional staff, and that practices in metropolitan areas were more likely to have experienced practice mergers in the past 12 months than those in nonmetropolitan areas. We also found that practice size and geographic location were related to higher likelihoods of anticipating practice mergers, sales, and purchases in the future.

Objective The objective of this study was to establish an evidence-based clinical practice guideline for the primary management of obstetrical brachial plexus injury (OBPI). This clinical practice guideline addresses 4 existing gaps: (1) historic poor use of evidence, (2) timing of referral to multidisciplinary care, (3) Indications and timing of operative nerve repair and (4) distribution of expertise. Setting The guideline is intended for all healthcare providers treating infants and children, and all specialists treating upper extremity injuries. Participants The evidence interpretation and recommendation consensus team (Canadian OBPI Working Group) was composed of clinicians representing each of Canada's 10 multidisciplinary centres. Outcome measures An electronic modified Delphi approach was used for consensus, with agreement criteria defined a priori. Quality indicators for referral to a multidisciplinary centre were established by consensus. An original meta-analysis of primary nerve repair and review of Canadian epidemiology and burden were previously completed. Results 7 recommendations address clinical gaps and guide identification, referral, treatment and outcome assessment: (1) physically examine for OBPI in newborns with arm asymmetry or risk factors; (2) refer newborns with OBPI to a multidisciplinary centre by 1 month; (3) provide pregnancy/birth history and physical examination findings at birth; (4) multidisciplinary centres should include a therapist and peripheral nerve surgeon experienced with OBPI; (5) physical therapy should be advised by a multidisciplinary team; (6) microsurgical nerve repair is indicated in root avulsion and other OBPI meeting centre operative criteria; (7) the common data set includes the Narakas classification, limb length, Active Movement Scale (AMS) and Brachial Plexus Outcome Measure (BPOM) 2 years after birth/surgery. Conclusions The process established a new network of opinion leaders and researchers for further

The National Practice Benchmark (NPB) is a unique tool used to measure oncology practices against others across the country in a meaningful way despite variations in practice demographics, size, and setting. In today’s challenging economic environment, each practice positions service offerings and competitive advantages to attract patients. Although the data in the NPB report are primarily reported by community oncology practices, the business structure and arrangements with regional health care systems are also reflected in the benchmark report. The ability to produce detailed metrics is an accomplishment of excellence in business and clinical management. With these metrics, a practice should be able to measure and analyze its current business practices and make appropriate changes, if necessary. In this report, we build on the foundation initially established by Oncology Metrics (acquired by Flatiron Health in 2014) over years of data collection and refine definitions to deliver the NPB, which is uniquely meaningful in the oncology market.

A survey of members of the National Abortion Federation (NAF), most of them non-hospital facilities, responsible for performing almost half of the abortions in the United States, was carried out by the NAF in 1981. Among the principal findings were the following: Fifty-three percent of the NAF facilities are freestanding clinics operated for profit. Fifty-one percent are open more than 50 hours per week, and 77 percent are open six days a week; 86 percent are open on Saturdays. Seventy-five percent of the physicians performing abortions in these facilities are gynecologists. Counseling provided by specially trained abortion counselors is a unique contribution of abortion facilities to health-care delivery. Virtually all facilities employ counselors who are neither doctors nor nurses. Most NAF facilities have more counselors than nurses and more nurses than doctors. Counseling in virtually all facilities includes providing written as well as verbal information about the nature of the procedure and its medical risks; such information is given to the patient so that she can give informed consent for the abortion. Almost all facilities include information about contraception and about the options available to a woman with a problem pregnancy. Most offer counseling to the male, as well as the female partner, on the patient's request. Twenty-eight percent of facilities generally provide both individual and group counseling. Where only one type of counseling is provided, it is usually individual counseling.(ABSTRACT TRUNCATED AT 250 WORDS)

Background Although breast cancer surgery is regarded as a “clean” surgery, surgical site infection (SSI) rates are higher than expected. There is no consensus regarding the use of antibiotic prophylaxis in elective breast surgery. The nationwide survey was conducted to determine the trend of antibiotic prophylaxis in breast cancer among Turkish surgeons. Methods The survey was sent to surgeons who are member of Turkish Surgical Association (TSA) via e-mail from TSA web address. A 15 item web-based survey consisted of surgeon demographics and the use of prophylactic antibiotic in patients with risk factors related to SSI. Results The number of completed questionnaires was 245. The most common antibiotic used was first generation of cephalosporins. A majority of respondents indicated that prophylaxis was preferred in patients with high risk of SSI including preoperative chemotherapy or radiotherapy, older age, diabetes mellitus, immunodeficiency, immediate reconstruction (P < 0.05). However, the use of drain did not significantly influence antibiotic prophylaxis (P = 0.091). Conclusions The use of prophylactic antibiotic was strongly dependent on the presence of some risk factors; however, the variation in current practice regarding antibiotic prophylaxis demonstrated a lack of its effect on preventing SSI after breast cancer surgery.

Background There is consensus about the importance of ‘recovery’ in mental health services, but the link between recovery orientation of mental health teams and personal recovery of individuals has been underresearched. Aims To investigate differences in team leader, clinician and service user perspectives of recovery orientation of community adult mental health teams in England. Method In six English mental health National Health Service (NHS) trusts, randomly chosen community adult mental health teams were surveyed. A random sample of ten patients, one team leader and a convenience sample of five clinicians were surveyed from each team. All respondents rated the recovery orientation of their team using parallel versions of the Recovery Self Assessment (RSA). In addition, service users also rated their own personal recovery using the Questionnaire about Processes of Recovery (QPR). Results Team leaders (n = 22) rated recovery orientation higher than clinicians (n = 109) or patients (n = 120) (Wald(2) = 7.0, P = 0.03), and both NHS trust and team type influenced RSA ratings. Patient-rated recovery orientation was a predictor of personal recovery (b = 0.58, 95% CI 0.31–0.85, P<0.001). Team leaders and clinicians with experience of mental illness (39%) or supporting a family member or friend with mental illness (76%) did not differ in their RSA ratings from other team leaders or clinicians. Conclusions Compared with team leaders, frontline clinicians and service users have less positive views on recovery orientation. Increasing recovery orientation may support personal recovery.

Blood transfusion is not without risk. Although the risks of HIV and hepatitis transmission have diminished, haemovigilance programs highlight that other significant transfusion hazards remain. Sepsis from bacterial contamination is the most common residual infectious hazard in developed countries, and events due to clerical error are problematic. Unnecessary transfusions should be avoided. New national guidelines on patient blood management (PBM) emphasise holistic approaches, including strategies to reduce transfusion requirements. Perioperative PBM should incorporate preoperative haemoglobin and medication optimisation, intraoperative blood conservation, and consideration of restrictive postoperative transfusion and cell-salvage techniques. When massive transfusion is required, hospitals should implement massive transfusion protocols. These protocols reduce mortality, improve communication and facilitate adequate provision of blood products. They should include multidisciplinary team involvement and guidelines for use of blood components and adjunctive agents. Although fresh frozen plasma to red blood cell and platelet to red blood cell ratios of ≥ 1 : 2 appear to reduce mortality in trauma patients who receive massive transfusion, there is insufficient evidence to recommend specific ratios. Systematic reviews have found no significant benefit of recombinant activated factor VII in critical bleeding, and an increase in thromboembolic events; specialist haematology advice is therefore recommended when considering use of this agent. The National Safety and Quality Health Service Standards address use of blood and blood products, and provide important transfusion principles for adoption by all clinicians. Storage of red cells in additive solution results in changes, known as the "storage lesion", and studies to determine the clinical effect of the age of blood at transfusion are ongoing.

ASBSTRACT Disinfection should be required for all skin penetrative procedures including parenteral administration of vaccines. This review analyses medically attended infectious events following parenteral vaccination in terms of their microbiological aetiology and pathogenesis. Like ‘clean’ surgical site infections, the major pathogens responsible for these events were Staphylococcal species, implicating endogenous con-tamination as a significant source of infection. As 70% isopropyl alcohol swabbing has been shown to effectively disinfect the skin, it would be medico-legally difficult to defend a case of sepsis with the omission of skin disinfection unless the very low risk of this event was adequately explained to the patient and documented prior to vaccination. There was a significant cost-benefit for skin disinfection and cellulitis. Skin disinfection in the context of parenteral vaccination represents a new paradigm of medical practice; the use of a low cost intervention to prevent an event of very low prevalence but of significant cost.

International experts reviewed and updated the most recent and relevant scientific advances on severe sepsis during the 17th International Symposium on Infections in the Critically Ill Patients in Barcelona (Spain) in February 2012. All new pharmacological therapeutic strategies have failed to demonstrate a survival benefit. Despite the large variability among countries and hospitals, the improvement of standard care according to the Surviving Sepsis campaign recommendations reduced the 28-day mortality to 24%. These results may have implications for future clinical trials in which much larger samples sizes of patients at high risk of death will be necessary. The identification of novel proinflammatory endogeneous signals and pathways may lead to the discovery of new drugs to reduce inflammatory reactions and end-organ dysfunction in critically ill patients with sepsis. Extracorporeal blood purification stem or progenitor cells have received increasing interest for the treatment of inflammation and organ injury. A better understanding of how these therapies work is essential and its benefit should be confirmed in future prospective randomized studies.

SEP-1, the new national quality measure on sepsis, resulted from an undertaking to standardize care for severe sepsis and septic shock regardless of the size of the emergency department where the patient is being treated. SEP-1 does not necessarily follow the best current evidence available. Nevertheless, a thorough understanding of SEP-1 is crucial because all hospitals and emergency providers will be accountable for meeting the requirements of this measure. SEP-1 is the first national quality measure on early management of sepsis care. This article provides a review of SEP-1 and all its potential implications on sepsis care in the United States.

Resuscitation goals for the patient with sepsis and septic shock are to return the patient to a physiologic state that promotes adequate end-organ perfusion along with matching metabolic supply and demand. Ideal resuscitation end points should assess the adequacy of tissue oxygen delivery and oxygen consumption, and be quantifiable and reproducible. Despite years of research, a single resuscitation end point to assess adequacy of resuscitation has yet to be found. Thus, the clinician must rely on multiple end points to assess the patient's overall response to therapy. This review will discuss the role and limitations of central venous pressure (CVP), mean arterial pressure (MAP), and cardiac output/index as macrocirculatory resuscitation targets along with lactate, central venous oxygen saturation (ScvO2), central venous-arterial CO2 gradient, urine output, and capillary refill time as microcirculatory resuscitation endpoints in patients with sepsis.

Despite the production and dissemination of recommendations related to managing fever in children, this symptom saturates the practices of primary healthcare professionals (HPs). Data on parent practices related to fever are available, but data on HPs' practices are limited. We studied HPs' practices, determinants of practices and concordance with recommendations in France. We conducted a national cross-sectional observational study between 2007 and 2008 among French general practitioners, primary care pediatricians and pharmacists. HPs were asked to include 5 consecutive patients aged 1 month to 12 years with acute fever. HPs completed a questionnaire about their practices for the current fever episode. We used a multilevel logistic regression model to assess the joint effects of patient- and HP-level variables associated with this behavior. In all, 1,534 HPs (participation rate 13%) included 6,596 children (mean age 3.7 ± 2.7 years). Physicians measured the temperature of 40% of children. Primary HPs recommended drug treatment for 84% of children (including monotherapy for 92%) and physical treatment for 62% (including all recommended physical treatments for 7%). HPs gave written advice or a pamphlet for 13% of children. Significant practice variations were associated with characteristics of the child (age, fever level and diagnosis) and HP (profession and experience). In France, despite the production and dissemination of national recommendations for managing fever in children, primary HPs' observed practices differed greatly from current recommendations, which suggests potential targets for continuing medical education.

SUMMARY Early-onset sepsis remains a common and serious problem for neonates, especially preterm infants. Group B streptococcus (GBS) is the most common etiologic agent, while Escherichia coli is the most common cause of mortality. Current efforts toward maternal intrapartum antimicrobial prophylaxis have significantly reduced the rates of GBS disease but have been associated with increased rates of Gram-negative infections, especially among very-low-birth-weight infants. The diagnosis of neonatal sepsis is based on a combination of clinical presentation; the use of nonspecific markers, including C-reactive protein and procalcitonin (where available); blood cultures; and the use of molecular methods, including PCR. Cytokines, including interleukin 6 (IL-6), interleukin 8 (IL-8), gamma interferon (IFN-γ), and tumor necrosis factor alpha (TNF-α), and cell surface antigens, including soluble intercellular adhesion molecule (sICAM) and CD64, are also being increasingly examined for use as nonspecific screening measures for neonatal sepsis. Viruses, in particular enteroviruses, parechoviruses, and herpes simplex virus (HSV), should be considered in the differential diagnosis. Empirical treatment should be based on local patterns of antimicrobial resistance but typically consists of the use of ampicillin and gentamicin, or ampicillin and cefotaxime if meningitis is suspected, until the etiologic agent has been identified. Current research is focused primarily on development of vaccines against GBS. PMID:24396135

To investigate the relation between biosensor of endotoxin and endotoxin of plasma in sepsis. Method: biosensor of endotoxin was designed with technology of quartz crystal microbalance bioaffinity sensor ligand of endotoxin were immobilized by protein A conjugate. When a sample soliton of plasma containing endotoxin 0.01, 0.03, 0.06, 0.1, 0.5, 1.0Eu, treated with perchloric acid and injected into slot of quartz crystal surface respectively, the ligand was released from the surface of quartz crystal to form a more stable complex with endotoxin in solution. The endotoxin concentration corresponded to the weight change on the crystal surface, and caused change of frequency that occurred when desorbed. The result was biosensor of endotoxin might detect endotoxin of plasma in sepsis, measurements range between 0.05Eu and 0.5Eu in the stop flow mode, measurement range between 0.1Eu and 1Eu in the flow mode. The sensor of endotoxin could detect the endotoxin of plasm rapidly, and use for detection sepsis in clinically.

Severe sepsis is a clinical emergency. Despite the nationwide recognition of the sepsis six treatment bundle as the first line emergency treatment for this presentation, compliance in sepsis six provision remains inadequately low. The project goals were to improve compliance with the implementation of the Sepsis Six in patients with severe sepsis and/or septic shock. In improving timely care delivery it was anticipated improvements would be made in relation to patient safety and experience, and reductions in length of stay (LoS) and mortality. The project intended to make the pathway for those presenting with sepsis safe and consistent, where sepsis is recognised and treated in a timely manner according to best practice. The aim of the project was to understand the what the barriers where to providing safe effective care for the patient presenting with severe sepsis in A&E. Using the Safer Clinical Systems (SCS) tools developed byte Health Foundation and Warwick University, the project team identified the hazards and associated risks in the septic patient pathway. The level of analysis employed enabled the project team to identify the major risks, themes, and factors of influence within this pathway. The analysis identified twenty nine possible interventions, of which six were chosen following option appraisal. Further interventions were recommended to the accident and emergency as part of a business case and further changes in process. Audits identified all severely septic patients presenting to A&E in October 2014 (n=67) and post intervention in September 2015 (n=93). Compared analysis demonstrated an increase in compliance with the implementation of the sepsis six care bundle from 7% to 41%, a reduction in LoS by 1.9 days and a decrease in 30 day mortality by 50%. Additional audit reviewed the management of 10 septic patients per week for the duration of the project to assess the real time impact of the selected interventions. PMID:27752314

Septic shock is characterized by circulatory compromise, microcirculatory alterations and mitochondrial damage, which all reduce cellular energy production. In order to reduce the risk of major cell death and a diminished likelihood of recovery, adaptive changes appear to be activated. As a result, cells and organs may survive in a non-functioning hibernation-like condition. Sepsis-induced cardiac dysfunction may represent an example of such functional shutdown. Sepsis-induced myocardial dysfunction is common, corresponds to the severity of sepsis, and is reversible in survivors. Its mechanisms include the attenuation of the adrenergic response at the cardiomyocyte level, alterations of intracellular calcium trafficking and blunted calcium sensitivity of contractile proteins. All these changes are mediated by cytokines. Treatment includes preload optimization with sufficient fluids. However, excessive volume loading is harmful. The first line vasopressor recommended at present is norepinephrine, while vasopressin can be started as a salvage therapy for those not responding to catecholamines. During early sepsis, cardiac output can be increased by dobutamine. While early administration of catecholamines might be necessary to restore adequate organ perfusion, prolonged administration might be harmful. Novel therapies for sepsis-induced cardiac dysfunction are discussed in this article. Cardiac inotropy can be increased by levosimendan, istaroxime or omecamtiv mecarbil without greatly increasing cellular oxygen demands. Heart rate reduction with ivabradine reduces myocardial oxygen expenditure and ameliorates diastolic filling. Beta-blockers additionally reduce local and systemic inflammation. Advances may also come from metabolic interventions such as pyruvate, succinate or high dose insulin substitutions. All these potentially advantageous concepts require rigorous testing before implementation in routine clinical practice.

The recent proceedings of congresses and forums on sepsis were used to write this review. The available definitions of sepsis and ideas on its etiology and pathogenesis are critically analyzed. There is information on new concepts of sepsis and data on a search for new targets, diagnostic and therapeutic approaches, and biomarkers. It is hypothesized that there is a mechanism of action of bacteria on mitochondrial dysfunction and human hormonal regulation with low-molecular weight exometabolites, namely aromatic microbial metabolites.

Late onset neonatal sepsis is one of the major clinical concerns when premature babies receive intensive care. Current practice relies on slow laboratory testing of blood cultures for diagnosis. A valuable research question is whether sepsis can be reliably detected before the blood sample is taken. This paper investigates the extent to which physiological events observed in the patient's monitoring traces could be used for the early detection of neonatal sepsis. We model the distribution of these events with an autoregressive hidden Markov model (AR-HMM). Both learning and inference carefully use domain knowledge to extract the baby's true physiology from the monitoring data. Our model can produce real-time predictions about the onset of the infection and also handles missing data. We evaluate the effectiveness of the AR-HMM for sepsis detection on a dataset collected from the Neonatal Intensive Care Unit at the Royal Infirmary of Edinburgh.

Purpose of review This review discusses the rational development of guidelines for the management of neonatal sepsis in developing countries. Recent findings Diagnosis of neonatal sepsis with high specificity remains challenging in developing countries. Aetiology data, particularly from rural, community based studies are very limited, but molecular tests to improve diagnostics are being tested in a community-based study in South Asia. Antibiotic susceptibility data are limited, but suggest reducing susceptibility to first and second line antibiotics in both hospital and community acquired neonatal sepsis. Results of clinical trials in South Asia and sub-Saharan Africa assessing feasibility of simplified antibiotic regimens are awaited. Summary Effective management of neonatal sepsis in developing countries is essential to reduce neonatal mortality and morbidity. Simplified antibiotic regimens are currently being examined in clinical trials, but reduced antimicrobial susceptibility threatens current empiric treatment strategies. Improved clinical and microbiological surveillance is essential, to inform current practice, treatment guidelines, and monitor implementation of policy changes. PMID:25887615

Sepsis is the main cause of close to 70% of all cases of acute respiratory distress syndromes (ARDS). In addition, sepsis increases susceptibility to ventilator-induced lung injury. Therefore, the development of a ventilatory strategy that can achieve adequate oxygenation without injuring the lungs is highly sought after for patients with acute infection and represents an important therapeutic window to improve patient care. Suboptimal ventilatory settings cannot only harm the lung, but may also contribute to the cascade of organ failure in sepsis due to organ crosstalk.Despite the prominent role of sepsis as a cause for lung injury, most of the studies that addressed mechanical ventilation strategies in ARDS did not specifically assess sepsis-related ARDS patients. Consequently, most of the recommendations regarding mechanical ventilation in sepsis patients are derived from ARDS trials that included multiple clinical diagnoses. While there have been important improvements in general ventilatory management that should apply to all critically ill patients, sepsis-related lung injury might still have particularities that could influence bedside management.After revisiting the interplay between sepsis and ventilation-induced lung injury, this review will reappraise the evidence for the major components of the lung protective ventilation strategy, emphasizing the particularities of sepsis-related acute lung injury.

Sepsis represents a unique clinical dilemma with regard to antimicrobial stewardship. The standard approach to suspected sepsis in the emergency department centers on fluid resuscitation and timely broad-spectrum antimicrobials. The lack of gold standard diagnostics and evolving definitions for sepsis introduce a significant degree of diagnostic uncertainty that may raise the potential for inappropriate antimicrobial prescribing. Intervention bundles that combine traditional quality improvement strategies with emerging electronic health record-based clinical decision support tools and rapid molecular diagnostics represent the most promising approach to enhancing antimicrobial stewardship in the management of suspected sepsis in the emergency department.

Sepsis is a common condition managed in the emergency department. Current diagnosis relies on physiologic criteria and suspicion of a source of infection using history, physical examination, laboratory studies, and imaging studies. The infection triggers a host response with the aim to destroy the pathogen, and this response can be measured. A reliable biomarker for sepsis should assist with earlier diagnosis, improve risk stratification, or improve clinical decision making. Current biomarkers for sepsis include lactate, troponin, and procalcitonin. This article discusses the use of lactate, procalcitonin, troponin, and novel biomarkers for use in sepsis.

Strict federal regulations govern the possession, use, and transfer of pathogens and toxins with potential to cause harm to the public, either through accidental or deliberate means. Laboratories registered through either the Centers for Disease Control and Prevention (CDC), the U.S. Dept. of Agriculture (USDA), or both, must prepare biosafety, security, and incident response plans, conduct drills or exercises on an annual basis, and update plans accordingly. At the Idaho National Laboratory (INL), biosafety, laboratory, and emergency management staff have been working together for 2 years to satisfy federal and DOE/NNSA requirements. This has been done through the establishment of plans, training, tabletop and walk-through exercises and drills, and coordination with local and regional emergency response personnel. Responding to the release of infectious agents or toxins is challenging, but through familiarization with the nature of the hazardous biological substances or organisms, and integration with laboratory-wide emergency response procedures, credible scenarios are being used to evaluate our ability to protect workers, the public, and the environment from agents we must work with to provide for national biodefense.
Health promotion-disease prevention programs share with health behavior research the common objective of identifying population subgroups toward whom services can be targeted. For this report, six age-sex groups were examined to determine similarities and differences in the predictors of eight health practice indices. Data were from the 1979 National Survey of Personal Health Practices and Consequences. Results showed very little similarity of predictors across the three age cohorts (20-34, 35-49, 50-64), between men and women, and among the six age-sex groups. No predictor achieved significance consistently for several health practices in any of the six groups, although years of education made the best showing. The lack of overlap among predictors helps to explain why health promotion messages and recruitment strategies may not appeal to as diverse an audience as initially intended. Possible explanations for the absence of similar predictors include differences in the nature of the various practices themselves, absence of data on intentions behind a person's behavior, and the "over-determined" character of an individual person's behavior.

Neonatal sepsis is one of the major health problems throughout the world. Every year an estimated 30 million newborns acquire infection and 1-2 million of these die. The present review provides updates regarding neonatal sepsis to help paediatricians to protect the newborn from this deadly problem. The onset of sepsis within first 48 hours of life (early onset sepsis) is frequently associated with pre and perinatal predisposing factors while onset after 48-72 hours of life (late onset sepsis) frequently reflects infection acquired nosocomially. Some literatures say that early onset disease presents in the first 5-7 days of life. Klebsiella pneumoniae is the leading pathogen causing neonatal sepsis in Bangladesh and neighbouring countries. Among many risk factors the single most important neonatal risk factor is low birth weight. Other main risk factors are invassive procedures in the postnatal period and inadequate hand washing before and after handling babies. Sepsis score is a useful method for early and rapid diagnosis of neonatal sepsis which was developed by Tollner U in 1982. Antibiotics should be given to most of the neonates suspected of infection. Ampicillin and gentamicin are the first drug of choice. In Bangladesh context sepsis score may be used as a good parameter for the early and rapid diagnosis of sepsis and that will guide the treatment plan. Clean and safe delivery, early and exclusive breastfeeding, strict postnatal cleanliness following adequate handwashing and aseptic technique during invasive procedure might reduce the incidence of neonatal sepsis. Prompt use of antibiotic according to standard policy is warranted to save the newborn lives from septicaemia.

The salient steps of a 20-year programme of research into the nature of burn disease are described. By burn disease we mean the late mortality and morbidity following burns. We have isolated a burn toxin which is derived from a thermal polymerization of cell membrane lipoproteins within the dermis and have studied its influence on the effects of sepsis. We have also used it in the development of active and passive immunization therapy of severe burns. ImagesFig. 2Fig. 5Fig. 6Fig. 7Fig. 8Fig. 9 PMID:4429330
Most important event of year 2004 of the history of Hungarian pharmacy was the release of the 7th edition of the National Formulary. The general part of the new formulary expanded, remarks on the preparations are more detailed and dispensing technologies are more elaborated. Knowledge base on pharmaceutical substances and incompatibility is inserted as novelty. Following the principles of modern pharmacy practice the new National Formulary excludes pills, though it is still accepted as an alternative dosage form. Usage of tablets, hard gelatine capsules and medication stick as a new dosage forms are introduced. The aim of my study was to prepare and examine some new compositions of the new edition of the National Formulary to help the pharmacist's work. Results confirmed the novel solutions of the new National Formulary.

Sepsis is a major cause of mortality and morbidity in intensive care units. Organ dysfunction is triggered by inflammatory insults and tissue hypoperfusion. The brain plays a pivotal role in sepsis, acting as both a mediator of the immune response and a target for the pathologic process. The measurement of brain dysfunction is difficult because there are no specific biomarkers of neuronal injury, and bedside evaluation of cognitive performance is difficult in an intensive care unit. Although sepsis-associated encephalopathy was described decades ago, it has only recently been subjected to scientific scrutiny and is not yet completely understood. The pathophysiology of sepsis-associated encephalopathy involves direct cellular damage to the brain, mitochondrial and endothelial dysfunction and disturbances in neurotransmission. This review describes the most recent findings in the pathophysiology, diagnosis, and management of sepsis-associated encephalopathy and focuses on its many presentations. PMID:22012058

One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies (PIDs) have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseudomonas aeruginosa (P. aeruginosa) is a common bacterium mostly associated with health care-related infections in immunocompromised individuals. However, in rare cases, it can cause sepsis in previously healthy children. We used exome sequencing and bioinformatic analysis to systematically search for genetic factors underpinning severe P. aeruginosa infection in the pediatric population. We collected blood samples from 11 previously healthy children, with no family history of immunodeficiency, who presented with severe sepsis due to community-acquired P. aeruginosa bacteremia. Genomic DNA was extracted from blood or tissue samples obtained intravitam or postmortem. We obtained high-coverage exome sequencing data and searched for rare loss-of-function variants. After rigorous filtrations, 12 potentially causal variants were identified. Two out of eight (25%) fatal cases were found to carry novel pathogenic variants in PID genes, including BTK and DNMT3B. This study demonstrates that exome sequencing allows to identify rare, deleterious human genetic variants responsible for fulminant sepsis in apparently healthy children. Diagnosing PIDs in such patients is of high relevance to survivors and affected families. We propose that unusually severe and fatal sepsis cases in previously healthy children should be considered for exome/genome sequencing to search for underlying PIDs.

Summary Objectives. In El Salvador, before 1999, morbidity and mortality in severely burned children were high. In 1998, all children with burns of 40% or larger size died and sepsis was found. With heparin use in 1999, some similarly burned children survived, and sepsis, pain, procedures, and scars were noted to be less. This retrospective study presents the details. Methods. A study was conducted at the National Children's Hospital in El Salvador of all children with burns over 20% size treated in 1998, when no heparin was used, and in 1999, when heparin was added to burns treatment, using an ethics committee approved protocol in use in twelve other countries. Sodium aqueous heparin solution USP from an intestinal source was infused intravenously and applied topically onto burn surfaces and within blisters for the first 1-3 days post-burn. Then heparin, in diminishing doses, was continued only topically until healing. The treatments in 1998 and 1999 were otherwise the same, except that fewer procedures were needed in 1999. Results. There were no significant differences in gender, age, weight, burn aetiology, or burn size between the burned children in 1998 and those in 1999. Burn pain was relieved and pain medicine was not needed in children treated with heparin in 1999. In 1998, one child survived who had a 35% size burn, and the eight children died who had burns of 40% and over. The survival rate was one out of nine (11%). The average burn size was 51.7%. With heparin use in 1999, six of the ten children survived burns of 50.7% average size. The increase in survival with heparin from 11% to 60% and, therefore, the decrease in mortality from 89% to 40% were significant (p < 0.04). Clinical symptoms and positive blood cultures documented bacterial sepsis in the nine children in 1998. In 1999, the blood cultures for sepsis were positive in the four children who died and negative in the six who survived. The nine versus four differences in the incidence of sepsis

The National Practice Benchmark (NPB) is a unique tool to measure oncology practices against others across the country in a way that allows meaningful comparisons despite differences in practice size or setting. In today's economic environment every oncology practice, regardless of business structure or affiliation, should be able to produce, monitor, and benchmark basic metrics to meet current business pressures for increased efficiency and efficacy of care. Although we recognize that the NPB survey results do not capture the experience of all oncology practices, practices that can and do participate demonstrate exceptional managerial capability, and this year those practices are recognized for their participation. In this report, we continue to emphasize the methodology introduced last year in which we reported medical revenue net of the cost of the drugs as net medical revenue for the hematology/oncology product line. The effect of this is to capture only the gross margin attributable to drugs as revenue. New this year, we introduce six measures of clinical data density and expand the radiation oncology benchmarks.

Late-onset neonatal sepsis is a significant cause of morbidity and mortality, and early detection could prove beneficial. Previously, we found that abnormal heart rate characteristics (HRC) of reduced variability and transient decelerations occurred early in the course of neonatal sepsis and sepsis-like illness in infants in a single neonatal intensive care unit (NICU). We hypothesized that this finding can be generalized to other NICUs. We prospectively collected clinical data and continuously measured RR intervals in all infants in two NICUs who stayed for >7 d. We defined episodes of sepsis and sepsis-like illness as acute clinical deteriorations that prompted physicians to obtain blood cultures and start antibiotics. A predictive statistical model yielding an HRC index was developed on a derivation cohort of 316 neonates in the University of Virginia NICU and then applied to the validation cohort of 317 neonates in the Wake Forest University NICU. In the derivation cohort, there were 155 episodes of sepsis and sepsis-like illness in 101 infants, and in the validation cohort, there were 118 episodes in 93 infants. In the validation cohort, the HRC index 1) showed highly significant association with impending sepsis and sepsis-like illness (receiver operator characteristic area 0.75, p < 0.001) and 2) added significantly to the demographic information of birth weight, gestational age, and days of postnatal age in predicting sepsis and sepsis-like illness (p < 0.001). Continuous HRC monitoring is a generally valid and potentially useful noninvasive tool in the early diagnosis of neonatal sepsis and sepsis-like illness.

Background The patient list system in Denmark assigns virtually all residents to a general practice. Nevertheless, historical information on this link between patient and general practice is not readily available for research purposes. Objectives To develop, implement, and evaluate the performance of an algorithm linking individual patients to their general practice by using information from the Danish National Health Service Register and the Danish Civil Registration System. Materials and methods The National Health Service Register contains information on all services provided by general practitioners from 1990 and onward. On the basis of these data and information on migration history and death obtained from the Civil Registration System, we developed an algorithm that allocated patients to a general practice on a monthly basis. We evaluated the performance of the algorithm between 2002 and 2007. During this time period, we had access to information on the link between patients and general practices. Agreement was assessed by the proportion of months for which the algorithm allocated patients to the correct general practice. We also assessed the proportion of all patients in the patient list system for which the algorithm was able to suggest an allocation. Results The overall agreement between algorithm and patient lists was 98.6%. We found slightly higher agreement for women (98.8%) than for men (98.4%) and lower agreement in the age group 18–34 years (97.1%) compared to all other age groups (≥98.6%). The algorithm had assigned 83% of all patients in the patient list system after 1 year of follow-up, 91% after 2 years of follow-up, and peaked at 94% during the fourth year. Conclusion We developed an algorithm that enables valid and nearly complete linkage between patients and general practices. The algorithm performs better in subgroups of patients with high health care needs. The algorithm constitutes a valuable tool for primary health care research. PMID

Sepsis describes a complex clinical syndrome that results from the host inability to regulate the inflammatory response against infection. Despite more than 20 years of extensive study, sepsis and excessive systemic inflammatory response syndrome (SIRS) are still the leading cause of death in intensive care units. The clinical study of sepsis and new therapeutics remains challenging due to the complexity of this disease. Therefore, many animal models have been employed to investigate the pathogenesis of sepsis and to preliminarily test potential therapeutics. However, so far, most therapeutics that have shown promising results in animal models failed in human clinical trials. In this chapter we will present an overview of different experimental animal models of sepsis and compare their advantages and disadvantage. The studies in animal models have greatly improved our understanding about the inflammatory mediators in sepsis. In this chapter we will also highlight the roles of several critical mediators including TNF-a , IL-1b , IL-6, chemokines, substance P, hydrogen sulfide and activated protein C in animal models of sepsis as well as in clinical studies.

Introduction Mindfulness-based practices can improve workers’ health and reduce employers’ costs by ameliorating the negative effect of stress on workers’ health. We examined the prevalence of engagement in 4 mindfulness-based practices in the US workforce. Methods We used 2002, 2007, and 2012 National Health Interview Survey (NHIS) data for adults (aged ≥18 y, n = 85,004) to examine 12-month engagement in meditation, yoga, tai chi, and qigong among different groups of workers. Results Reported yoga practice prevalence nearly doubled from 6.0% in 2002 to 11.0% in 2012 (P < .001); meditation rates increased from 8.0% in 2002 to 9.9% in 2007 (P < .001). In multivariable models, mindfulness practice was significantly lower among farm workers (odds ratio [OR] = 0.42; 95% confidence interval [CI], 0.21–0.83]) and blue-collar workers (OR = 0.63; 95% CI, 0.54–0.74) than among white-collar workers. Conclusion Worker groups with low rates of engagement in mindfulness practices could most benefit from workplace mindfulness interventions. Improving institutional factors limiting access to mindfulness-based wellness programs and addressing existing beliefs about mindfulness practices among underrepresented worker groups could help eliminate barriers to these programs.

Aim Genomics has the potential to improve personalized healthcare. Nurses are vital to the utilization of genomics in practice. This study assessed nursing attitudes, receptivity, confidence, competency, knowledge and practice in genomics to inform education efforts. Materials & methods Cross-sectional study of registered nurses who completed an online Genetic/Genomic Nursing Practice Survey posted on a national nursing organization website. Results A total of 619 registered nurses participated. The largest proportion of education level were nurses with a baccalaureate degree (39%). Most (67.5%) considered genomics very important to nursing practice. However, 57% reported their genomic knowledge base to be poor or fair. The mean total knowledge score correct response rate was 75%. Yet 60% incorrectly answered that diabetes and heart disease are caused by a single gene variant. Most (64%) had never heard of the Essential Nursing Competencies and Curricula Guidelines in Genomics. Higher academic education or post licensure genetic education increased family history collection in practice. Conclusion Most nurses are inadequately prepared to translate genomic information into personalized healthcare. Targeted genomic education is needed to assure optimal workforce preparation for genomics practice integration. PMID:24363765

Abstract A recent collecting trip to Vietnam yielded three new species and two new records of Sepsidae (Diptera) for the country. Here we describe two new species in the species-poor genus Perochaeta (Perochaeta cuirassa sp. n. andPerochaeta lobo sp. n.) and one to the largest sepsid genus Sepsis (Sepsis spura sp. n.) which is also found in Sumatra and Sulawesi. Two additional Sepsis species are new records for Vietnam (Sepsis sepsi Ozerov, 2003; Sepsis monostigma Thompson, 1869). We conclude with a discussion of the distribution of Perochaeta and the three Sepsis species. PMID:21594042

Objective To explore and categorise the state of existing literature for national programmes designed to affirm or establish the continuing competence of physicians. Design Scoping review. Data sources MEDLINE, ERIC, Sociological Abstracts, web/grey literature (2000–2014). Selection Included when a record described a (1) national-level physician validation system, (2) recognised as a system for affirming competence and (3) reported relevant data. Data extraction Using bibliographic software, title and abstracts were reviewed using an assessment matrix to ensure duplicate, paired screening. Dyads included both a methodologist and content expert on each assessment, reflective of evidence-informed best practices to decrease errors. Results 45 reports were included. Publication dates ranged from 2002 to 2014 with the majority of publications occurring in the previous six years (n=35). Country of origin—defined as that of the primary author—included the USA (N=32), the UK (N=8), Canada (N=3), Kuwait (N=1) and Australia (N=1). Three broad themes emerged from this heterogeneous data set: contemporary national programmes, contextual factors and terminological consistency. Four national physician validation systems emerged from the data: the American Board of Medical Specialties Maintenance of Certification Program, the Federation of State Medical Boards Maintenance of Licensure Program, the Canadian Revalidation Program and the UK Revalidation Program. Three contextual factors emerged as stimuli for the implementation of national validation systems: medical regulation, quality of care and professional competence. Finally, great variation among the definitions of key terms was identified. Conclusions There is an emerging literature focusing on national physician validation systems. Four major systems have been implemented in recent years and it is anticipated that more will follow. Much of this work is descriptive, and gaps exist for the extent to which systems build

The authors studied a possibility of obtaining experimental meningococcus sepsis model on mice. The use of cyclophosphane, iron compounds, yolk medium produced no significant organism. When 4--5% mucine was injected intraperitoneally together with meningococcus culture mice died with sepsis phenomena. Differences were revealed in the sensitivity of linear and mongrel mice to meningococcus infection--AKR mice proved to be more sensitive. At the same time it was found that mongrel mice weighing from 10 to 12 g could be used to induce meningococcus sepsis.

Sepsis is a challenging, dynamic, pathophysiology requiring expertise in diagnosis and management. Controversy exists as to the most sensitive early indicators of sepsis and sepsis severity. Patients presenting to the emergency department often lack complete history or clinical data that would point to optimal management. Awareness of these potential knowledge gaps is important for the emergency provider managing the septic patient. Specific areas of management including the initiation and management of mechanical ventilation, the appropriate disposition of the patient, and consideration of transfer to higher levels of care are reviewed.
Background Since the introduction of bone-anchored hearing aids (BAHAs) in the 1980s, the practices of surgeons who implant these hearing aids have become varied; different indications and surgical techniques are utilized depending on the surgeon and institution. The objective of the current study is to describe the clinical and surgical practices of otolaryngologists in Canada who perform pediatric BAHA operations. Methods A detailed practice questionnaire was devised and sent to all members of the Canadian Society of Otolaryngology-Head and Neck Surgery. Those who performed pediatric BAHA surgeries were asked to participate. Results Twelve responses were received (response rate of 80%). All of the respondents identified congenital aural atresia to be an indication for pediatric BAHAs. Other indications were chronic otitis externa or media with hearing loss (92%), allergic reactions to conventional hearing aids (75%), congenital fixation or anomaly of ossicular chain (67%), and unilateral deafness (25%). Minor complications, such as skin reactions, were reported in 25% of cases, while major complications were very rare. There was great variability with regards to surgical techinque and post-operative management. The extent of financial support for the BAHA hardware and device also varied between provinces, and even within the same province. Conclusion There is a lack of general consensus regarding pediatric BAHA surgeries in Canada. With such a small community of otolaryngologists performing this procedure, we are hopeful that this survey can serve as an impetus for a national collaboration to establish a set of general management principles and inspire multi-site research ventures.

Sepsis may be defined as a clinical syndrome caused by an organism's response to infection. The complex alterations triggered by the infection include inflammation and systemic coagulopathy in the absence of effective fibrinolysis. Possible manifestations vary in entity and severity, ranging from systemic inflammatory response syndrome (SIRS) to septic shock and multiorgan dysfunction syndrome (MODS). The nurse can play a fundamental role in the timely recognition of SIRS and in the early identification of the onset of signs of organ damage. In this way, an additional aid to establishing diagnosis can be provided and targeted treatment instituted. Following a brief presentation of the pathophysiology and epidemiology of sepsis, the manifestations and attendant risks are described, the most appropriate monitoring methods and the main nursing tasks in treating sepsis are discussed. We present the results of our experience in identifying patients with sepsis through the application of selection criteria adopted from clinical studies on the use of activated protein C.

Sepsis remains the leading cause of death in non-coronary ICU patients, despite improvements in supportive treatment modalities such as antimicrobial drugs and ventilation therapy. Further, the incidence of sepsis is projected to increase in years to come, related to factors including a rise in immunosuppressed patient populations and more widespread use of invasive lines and procedures. In this article, the authors seek to advance nurses' understanding of sepsis by reviewing the SIRS to septic shock paradigm and using a case study to illustrate how a patient progressed along the continuum. The role of the critical care nurse is an important aspect of the care of these patients. Early identification of patients at risk for, or who are developing, sepsis is crucial in order to improve patient outcomes.

Staghorn calculi are infrequent and generally are infected stones. Struvite or apatite calculi are embedded with gram-negative bacteria, which can produce endotoxin. Sepsis syndrome may occur after surgical therapy or endoscopic manipulation of infected or staghorn calculi. Sepsis, which can occur despite perioperative antibiotic use, may be due to bacteremia or endotoxemia. We present a child with an infected staghorn calculus who developed overwhelming sepsis and died after percutaneous stone manipulation. Endotoxin assay of stone fragments demonstrated an extremely high level of endotoxin despite low colony bacterial culture growth. This is the first reported case in which endotoxin was demonstrated in stone fragments from a child who died of severe sepsis syndrome after percutaneous staghorn stone manipulation.

Neuro-oxidative-nitrosative stress may prove the molecular basis underlying brain dysfunction in sepsis. In the current review, we describe how sepsis-induced reactive oxygen and nitrogen species (ROS/RNS) trigger lipid peroxidation chain reactions throughout the cerebrovasculature and surrounding brain parenchyma, due to failure of the local antioxidant systems. ROS/RNS cause structural membrane damage, induce inflammation, and scavenge nitric oxide (NO) to yield peroxynitrite (ONOO(-)). This activates the inducible NO synthase, which further compounds ONOO(-) formation. ROS/RNS cause mitochondrial dysfunction by inhibiting the mitochondrial electron transport chain and uncoupling oxidative phosphorylation, which ultimately leads to neuronal bioenergetic failure. Furthermore, in certain 'at risk' areas of the brain, free radicals may induce neuronal apoptosis. In the present review, we define a role for ROS/RNS-mediated neuronal bioenergetic failure and apoptosis as a primary mechanism underlying sepsis-associated encephalopathy and, in sepsis survivors, permanent cognitive deficits.

Background In-hospital cardiac arrest (IHCA) outcomes vary widely between hospitals, even after adjusting for patient characteristics, suggesting variations in practice as a potential etiology. However, little is known about the standards of IHCA resuscitation practice among US hospitals. Objective To describe current US hospital practices with regard to resuscitation care. Design A nationally representative mail survey. Setting A random sample of 1,000 hospitals from the American Hospital Association database, stratified into nine categories by hospital volume tertile and teaching status (major teaching, minor teaching and non-teaching). Subjects Surveys were addressed to each hospital's CPR Committee Chair or Chief Medical/Quality Officer. Measurements A 27-item questionnaire. Results Responses were received from 439 hospitals with a similar distribution of admission volume and teaching status as the sample population (p=0.50). Of the 270 (66%) hospitals with a CPR committee, 23 (10%) were chaired by a Hospitalist. High frequency practices included having a Rapid Response Team (91%) and standardizing defibrillators (88%). Low frequency practices included therapeutic hypothermia and use of CPR assist technology. Other practices such as debriefing (34%) and simulation training (62%) were more variable and correlated with the presence of a CPR Committee and/or dedicated personnel for resuscitation quality improvement. The majority of hospitals (79%) reported at least one barrier to quality improvement, of which the lack of a resuscitation champion and inadequate training were the most common. Conclusions There is wide variability between hospitals and within practices for resuscitation care in the US with opportunities for improvement. PMID:24550202

Several studies have investigated which management practices have the greatest effect on udder health, but little information is available on how broadly the recommended milking practices are adopted across Canada. The National Dairy Study 2015 was designed to gather dairy cattle health and management data on dairy farms across Canada. The objectives of the present study were to describe the current proportions of adoption of milking practices on Canadian dairy farms, and identify factors associated with their use on farms. A bilingual questionnaire measuring use of various practices, including an udder health-specific section, was developed and sent to all Canadian dairy farms. The questions in the udder health section of the questionnaire were adapted from a bilingual questionnaire previously validated and containing questions regarding general milking hygiene and routine, and on-farm mastitis management. Chi-squared tests were used to investigate simple associations between adoption of practices and various explanatory variables including region, milking system, herd size, and bulk tank somatic cell count. In total, 1,373 dairy producers completed the survey. The regional distribution of the participants was representative of the Canadian dairy farm population, and milk quality was, on average, similar to nonparticipants. Overall, Canadian dairy producers followed the recommendations for milking procedures, but some were more extensively used than others. Fore-stripping, cleaning teats, wiping teats dry, using single-cow towels, and use of postmilking teat disinfectant were widely adopted. Use of gloves and glove hygiene, use of a premilking teat disinfectant, and use of automatic takeoffs were not as extensively implemented. Adoption percentages for several practices, including use of gloves, use of a premilking teat disinfectant, teat drying methods, and use of automatic takeoffs were significantly associated with milking system, herd size, and region.

Sepsis has become a major health economic issue, with more patients dying in hospitals due to sepsis related complications compared to breast and colorectal cancer together. Despite extensive research in order to improve outcome in sepsis over the last few decades, results of large multicenter studies were by-and-large very disappointing. This fiasco can be explained by several factors, but one of the most important reasons is the uncertain definition of sepsis resulting in very heterogeneous patient populations, and the lack of understanding of pathophysiology, which is mainly based on the imbalance in the host-immune response. However, this heroic research work has not been in vain. Putting the results of positive and negative studies into context, we can now approach sepsis in a different concept, which may lead us to new perspectives in diagnostics and treatment. While decision making based on conventional sepsis definitions can inevitably lead to false judgment due to the heterogeneity of patients, new concepts based on currently gained knowledge in immunology may help to tailor assessment and treatment of these patients to their actual needs. Summarizing where we stand at present and what the future may hold are the purpose of this review. PMID:26258150

OBJECTIVES: Researchers examined physicians' treatment strategies for tuberculosis to determine whether they would follow recommendations of the Centers for Disease Control and Prevention and the American Thoracic Society. METHODS: A national survey sampled 1772 physicians. Analyses tested correlates of recommended treatment regimens. RESULTS: Among respondents, 59.4% described a recommended regimen. Specialists; physicians aware of professional publications, treatment recommendations, and reporting requirements; and those having more than 50% of patients in nursing homes were more likely to describe recommended regimens. Physicians who had been in practice longer, relied on personal experience, or had more than 50% of patients receiving Medicaid were less likely to describe recommended regimens. CONCLUSIONS: Physicians who treat tuberculosis require training and support. Policymakers should consider who should treat tuberculosis and how recommended practice should be ensured. PMID:9431292

Radiation Oncology Practice Standards have been developed over the last 10 years and were published for use in Australia in 2011. Although the majority of the radiation oncology community supports the implementation of the standards, there has been no mechanism for uniform assessment or governance. North Coast Cancer Institute's public radiation oncology service is provided across three main service centres on the north coast of NSW. With a strong focus on quality management, we embraced the opportunity to demonstrate conformity with the Radiation Oncology Practice Standards. The Local Health District's Clinical Governance units were engaged to perform assessments of our conformity with the standards and this was signed off as complete on 16 December 2013. The process of demonstrating conformity with the Radiation Oncology Practice Standards has enhanced the culture of quality in our centres. We have demonstrated that self-assessment utilising trained auditors is a viable method for centres to demonstrate conformity. National implementation of the Radiation Oncology Practice Standards will benefit individual centres and the broader radiation oncology community to improve the service delivered to our patients.

Background The leading cause of mortality in Mongolia is Non-Communicable Disease. Alcohol is recognised by the World Health Organization as one of the four major disease drivers and so, in order to better understand and triangulate recent national burden-of-disease surveys and to inform policy responses to alcohol consumption in Mongolia, a national Knowledge, Attitudes and Practices survey was conducted. Focusing on Non-Communicable Diseases and their risk factors, this publication explores the alcohol-related findings of this national survey. Methods A door-to-door, household-based questionnaire was conducted on 3450 people from across Mongolia. Participants were recruited using a multi-stage random cluster sampling technique, and eligibility was granted to permanent residents of households who were aged between 15 and 64 years. A nationally representative sample size was calculated, based on methodologies aligned with the WHO STEPwise approach to Surveillance. Results Approximately 50% of males and 30% of females were found to be current drinkers of alcohol. Moreover, nine in ten respondents agreed that heavy episodic drinking of alcohol is common among Mongolians, and the harms of daily alcohol consumption were generally perceived to be high. Indeed, 90% of respondents regarded daily alcohol consumption as either ‘harmful’ or ‘very harmful’. Interestingly, morning drinking, suggestive of problematic drinking, was highest in rural men and was associated with lower-levels of education and unemployment. Conclusion This research suggests that Mongolia faces an epidemiological challenge in addressing the burden of alcohol use and related problems. Males, rural populations and those aged 25-34 years exhibited the highest levels of risky drinking practices, while urban populations exhibit higher levels of general alcohol consumption. These findings suggest a focus and context for public health measures addressing alcohol-related harm in Mongolia. PMID

Aim: Neonatal sepsis is an important cause of mortality and morbidity in newborns. The causative agents may be different in different units and may change in time. It was aimed to examine the microbiological agents leading to sepsis, clinical features and antibiotic resistances in babies with sepsis hospitalized in our unit in a two-year period. Material and Methods: The clinical features, microbiological and laboratory results, antibiotic resistance patterns and mortality rates of the newborns with sepsis followed up in our unit between 2010 and 2011 were examined in the patient record system. Results: 351 babies diagnosed with sepsis among 3219 patients hospitalized in the neonatal intensive care unit were included in the study. The mean gestational age was found to be 30.1±4.1 weeks, the mean birth weight was found to be 1417.4±759.1 g and the mean hospitalization time was found to be 43.6±34.4 days. Blood cultures were found to be positive in 167 (47.6%) patients, urine cultures were found to be positive in 6 (7.1%) patients and cerebrospinal fluid cultures were found to be positive in 34 (9.6%) cases. Candida grew in 5 patients (2 patients with early-onset sepsis and 3 patients with late-onset sepsis). The most common cause of sepsis was found to be staphylococci (coagulase negative staphylococcus was found in 65 patients (51%) and Staphylococcus aureus was found in 38 patients (39%). 49.6% (n=63) of the gram positive bacteriae and 60% (n=21) of the gram negative bacteriae were resistant to antibiotics. Six (7.1%) of the patients who were infected with these bacteriae were lost. In total 24 babies were lost because of sepsis. The bacteriae which caused to mortality with the highest rate included E. coli, coagulase negative staphylocicci, S. aureus and Klebsiella. Low birth weight, mechanical ventilation and parenteral nutrition were found to be significant risk factors in terms of mortality. Conclusions: Staphylococci were found to be the most common agents

Inquiry has been one of the most prominent terms of the contemporary science education reform movement (Buck, Latta, & Leslie-Pelecky, 2007; Colburn, 2006; Settlage, 2007). Practicing classroom inquiry has maintained its central position in science education for several decades because science education reform documents promote classroom inquiry as the potential savior of science education from its current problems. Likewise, having the capabilities of teaching science through inquiry has been considered by National Board for Professional Teaching Standards [NBPTS] as one of the essential elements of being an accomplished science teacher. Successful completion of National Board Certification [NBC] assessment process involves presenting a clear evidence of enacting inquiry with students. Despite the high-profile of the word inquiry in the reform documents, the same is not true in schools (Crawford, 2007). Most of the science teachers do not embrace this type of approach in their everyday teaching practices of science (Johnson, 2006; Luera, Moyer, & Everett, 2005; Smolleck, Zembal-Saul, & Yoder, 2006; Trumbull, Scarano, & Bonney, 2006). And the specific meanings attributed to inquiry by science teachers do not necessarily match with the original intentions of science education reform documents (Matson & Parsons, 2006; Wheeler, 2000; Windschitl, 2003). Unveiling the various meanings held by science teachers is important in developing better strategies for the future success of science education reform efforts (Jones & Eick, 2007; Keys & Bryan, 2001). Due to the potential influences of National Board Certified Science Teachers [NBCSTs] on inexperienced science teachers as their mentors, examining inquiry conceptions of NBCSTs is called for. How do these accomplished practitioners understand and enact inquiry? The purpose of this dissertation research study was twofold. First, it investigated the role of NBC performance assessment process on the professional development

Sepsis, severe sepsis, and septic shock cause significant morbidity and mortality worldwide. Rapid diagnosis and therapeutic interventions are desirable to improve the overall mortality in patients with sepsis. However, gold standard laboratory diagnostic methods for sepsis, pose a significant challenge to rapid diagnosis of sepsis by physicians and laboratories. This article discusses the usefulness and potential of biomarkers and molecular test methods for a more rapid clinical and laboratory diagnosis of sepsis. Because new technologies are quickly emerging, physicians and laboratories must appreciate the key factors and characteristics that affect the clinical usefulness and diagnostic accuracy of these test methodologies.

Despite advances in the development of powerful antibiotics and intensive care unit, sepsis is still life threatening and the mortality rate remains unchanged for the past three decades. Recent prospective trials with biological response modifiers have shown a modest clinical benefit. The pathological basis of sepsis is initially an excessive inflammatory response against invading pathogens, leading to systemic inflammatory response syndrome (SIRS). Evidence reveals that a variety of inflammatory mediators orchestrate the intense inflammation through complicated cellular interactions. More recent data indicate that most septic patients survive this stage and then subjected to an immunoparalysis phase, termed compensatory anti-inflammatory response syndrome (CARS), which is more fatal than the initial phase. Sepsis is a complicated clinical syndrome with multiple physiologic and immunologic abnormalities. In this review, we summarize the recent understandings of the pathophysiology of sepsis, and introduce recent patents on diagnosis, treatment and prophylaxis for sepsis.

Burkholderia cepacia is a rare cause of sepsis in newborns and its transmission involves human contact with heavily contaminated medical devices and disinfectants. The authors aimed to determine epidemiology, clinical features, antibiotic sensitivity pattern, complications and outcome of blood culture proven B. cepacia infections in 12 neonates. All neonates were outborn, 5 preterm and 7 term. B. cepacia was isolated from blood in all and concurrently from CSF in three neonates. Lethargy and respiratory distress (41.7 %) were major presenting features. Five newborns (41.7 %) required mechanical ventilation for 3-7 d. Highest bacterial susceptibility was observed for meropenem (100 %), followed by cefoperazone-sulbactam, piperacillin-tazobactam, sulfamethoxazole-trimethoprim (all 83 %), ceftazidime (75 %) and ciprofloxacin (42 %). Piperacillin-tazobactam, ciprofloxacin and cotrimoxazole either singly or in combination led to complete recovery of 11 (91.7 %) newborns; one developed hydrocephalus. Eight of nine infants who completed 6 mo follow up were normal. Prompt recognition and appropriate antibiotic therapy for B. cepacia infection results in complete recovery in majority.
The clinical, human and economic burden associated with sepsis is huge. Initiatives such as the Surviving Sepsis Campaign aim to effectively reduce risk of death from severe sepsis and septic shock. Nonetheless, although substantial benefits raised from the implementation of this campaign have been obtained, much work remains if we are to realise the full potential promised by this strategy. A deeper understanding of the processes leading to sepsis is necessary before we can design an effective suite of interventions. Dysregulation of the immune response to infection is acknowledged to contribute to the pathogenesis of the disease. Production of both proinflammatory and immunosuppressive cytokines is observed from the very first hours following diagnosis. In addition, hypogammaglobulinemia is often present in patients with septic shock. Moreover, levels of IgG, IgM and IgA at diagnosis correlate directly with survival. In turn, nonsurvivors have lower levels of C4 (a protein of the complement system) than the survivors. Natural killer cell counts and function also seem to have an important role in this disease. HLA-DR in the surface of monocytes and counts of CD4+CD25+ T-regulatory cells in blood could also be useful biomarkers for sepsis. At the genomic level, repression of networks corresponding to major histocompatibility complex antigen presentation is observed in septic shock. In consequence, cumulative evidence supports the potential role of immunological monitoring to guide measures to prevent or treat sepsis in a personalised and timely manner (early antibiotic administration, immunoglobulin replacement, immunomodulation). In conclusion, although diffuse and limited, current available information supports the development of large comprehensive studies aimed to urgently evaluate immunological monitoring as a tool to prevent sepsis, guide its treatment and, as a consequence, diminish the morbidity and mortality associated with this severe condition.

Cells of the innate and adaptive immune systems play a critical role in the host response to sepsis. Moreover, their accessibility for sampling and their capacity to respond dynamically to an acute threat increases the possibility that leukocytes might serve as a measure of a systemic state of altered responsiveness in sepsis. The working group of the 14th Acute Dialysis Quality Initiative (ADQI) conference sought to obtain consensus on the characteristic functional and phenotypic changes in cells of the innate and adaptive immune system in the setting of sepsis. Techniques for the study of circulating leukocytes were also reviewed and the impact on cellular phenotypes and leukocyte function of non extracorporeal treatments and extracorporeal blood purification therapies proposed for sepsis was analyzed. A large number of alterations in the expression of distinct neutrophil and monocyte surface markers have been reported in septic patients. The most consistent alteration seen in septic neutrophils is their activation of a survival program that resists apoptotic death. Reduced expression of HLA-DR is a characteristic finding on septic monocytes but monocyte antimicrobial function does not appear to be significantly altered in sepsis. Regarding adaptive immunity, sepsis-induced apoptosis leads to lymphopenia in patients with septic shock and it involves all types of T cells (CD4, CD8 and Natural Killer) except T regulatory cells, thus favoring immunosuppression. Finally, numerous promising therapies targeting the host immune response to sepsis are under investigation. These potential treatments can have an effect on the number of immune cells, the proportion of cell subtypes and the cell function. PMID:26529661

Social marketing can be an effective tool for achieving public health goals. Social marketing uses concepts from commercial marketing to plan and implement programs designed to bring about behavior change that will benefit individuals and society. Although social marketing principles have been used to address public health problems, efforts have been dominated by message-based, promotion-only strategies, and effective implementation has been hampered by both lack of understanding of and use of all of the components of a social marketing approach and lack of training. The Turning Point initiative's Social Marketing National Excellence Collaborative (SMNEC) was established to promote social marketing principles and practices to improve public health across the nation. After 4 years, the Collaborative's work has resulted in improved understanding of social marketing among participating members and the development of new tools to strengthen the social marketing skills among public health practitioners. The Collaborative has also made advances in incorporating and institutionalizing the practice of social marketing within public health in participating states.

Individual recommendation plans (IRP) for student teaching practice were co-constructed with two methods students based on the select application of National Science Teachers Association’s National Standards for Science Teacher Preparation. Methods students completed a resume, an interview on pedagogical preferences, and a learning styles survey to determine the reform-based standards and pedagogical approaches that better fit their personal histories and identity formation as science teachers. Each case was unique with one student better meeting the Standards of “Issues” and “Science in the Community” and the other student better meeting the standards of “Inquiry” and the “Nature of Science”. Student teachers planned and taught lessons based on their IRP and were mostly successful in meeting their prescribed standards and utilizing their preferred pedagogies. However, their success in use of specific strategies supporting their approach was highly dependent upon classroom context. The use of the IRP process as a reflective tool strengthening identity formation and early practice is discussed.

Applying the principles of harm reduction within the context of incarcerated populations raises a number of challenges. Although some access to harm reduction strategies has been promoted in general society, a divide between what is available and what is advocated continues to exist within the prison system. This paper explores the perceptions and lived experiences of a sample of nationally incarcerated women in Canada regarding their perceptions and experiences in accessing HIV and Hepatitis C prevention, care, treatment and support. In-depth interviews were conducted with 156 women in Canadian national prisons. Q.S.R. Nudist was used to assist with data management. A constant comparison method was used to derive categories, patterns, and themes. Emergent themes highlighted a gap between access to harm reduction in policy and in practice. Despite the implementation of some harm reduction techniques, women in Canadian prisons reported variable access to both education and methods of reducing HIV/HCV transmission. Concerns were also raised about pre-and post-test counseling for HIV/HCV testing. Best practices are suggested for implementing harm reduction strategies within prisons for women in Canada.

Background Postpartum hemorrhage (PPH) continues to be one of the major causes of maternal mortality and morbidity in obstetrics. Variations in practice often lead to adverse maternity outcomes following PPH. Our objective was to assess the current practice in managing PPH in the UK. Methods We performed a national multicenter prospective service evaluation study over one calendar month and compared the current performance to national standards for managing PPH. We used a standardized data collection tool and collected data on patients’ demographics, incidence of PPH, estimated blood loss (EBL), prophylactic and treatment measures, onset of labor, and mode of delivery. Results We collected data from 98 obstetric units, including 3663 cases of primary PPH. Fifty percent of cases were minor PPH (EBL 500–1000 mL, n=1900/3613, 52.6%) and the remaining were moderate PPH (EBL >1000 to <2000 mL, n=1424/3613, 39.4%) and severe PPH (EBL >2000 mL, n=289/3613, 8%). The majority of women received active management of the third stage of labor (3504/3613, 97%) most commonly with Syntometrine intramuscular (1479/3613, 40.9%). More than half required one additional uterotonic agent (2364/3613, 65.4%) most commonly with Syntocinon intravenous infusion (1155/2364, 48.8%). There was a poor involvement of consultant obstetricians and anesthetists in managing PPH cases, which was more prevalent when managing major PPH (p=0.0001). Conclusion There are still variations in managing PPH in the UK against national guidelines. More senior doctor involvement and regular service evaluation are needed to improve maternal outcomes following PPH. PMID:28176919

Since the industrial sector consumes about two-thirds of China's primary energy, many of the country's efforts are focused on improving the energy efficiency of this sector. Industrial energy audits have become an important part of China's efforts to improve its energy intensity. In China, industrial energy audits have been employed to help enterprises indentify energy-efficiency improvement opportunities for achieving the energy-saving targets. These audits also serve as a mean to collect critical energy-consuming information necessary for governments at different levels to supervise enterprises energy use and evaluate their energy performance. To better understand how energy audits are carried out in China as well as their impacts on achieving China's energy-saving target, researchers at the Lawrence Berkeley National Laboratory (LBNL) conducted an in-depth study that combines a review of China's national policies and guidelines on energy auditing and a series of discussions with a variety of Chinese institutions involved in energy audits. This report consists of four parts. First, it provides a historical overview of energy auditing in China over the past decades, describing how and why energy audits have been conducted during various periods. Next, the report reviews current energy auditing practices at both the national and regional levels. It then discusses some of the key issues related to energy audits conducted in China, which underscore the need for improvement. The report concludes with policy recommendations for China that draw upon international best practices and aim to remove barriers to maximizing the potential of energy audits.

:Nurses are increasingly the primary contact for clients concerned about health problems related to their environment. In response to the need for nursing expertise in the field of environmental health, the Institute of Medicine (IOM), Agency for Toxic Substances and Disease Registry (ATSDR), and National Institute of Nursing Research (NINR) have designed core competencies for the nursing profession. The IOM competencies focus on four areas: (1) knowledge and concepts; (2) assessment and referral; advocacy, ethics, and risk communication; and (4) legislation and regulation. The competencies establish a baseline of knowledge and awareness in order for nurses to prevent and minimize health problems associated with exposure to environmental agents. To address the known difficulties of incorporating new priorities into established practice, nurses attending an environmental health short course participated in a nominal group process focusing on the question, "What specific actions can we take to bring environmental health into the mainstream of nursing practice?" This exercise was designed to bring the concepts of the national initiatives (IOM, NINR, ATSDR) to the awareness of individual nurses involved in the direct delivery of care. Results include 38 action items nurses identified as improving awareness and utilization of environmental health principles. The top five ideas were: (1) get environmental health listed as a requirement or competency in undergraduate nursing education; (2) improve working relationships with interdepartmental persons-a team approach; (3) strategically place students in essential organizations such as NIOSH, ATSDR, or CDC; (4) educate nurse educators; and (5) create environmental health awards in nursing. The 38 original ideas were also reorganized into a five-tiered conceptual model. The concepts of this model include: (1) developing partnerships; (2) strengthening publications; (3) enhancing continuing education; (4) updating nursing

Introduction With advancement in diagnostic techniques, the utilization of radiologic examination has risen to many folds in the last two decades. Ionizing radiations from the radiographic examination carry the potential for harm by inducing carcino-genesis in addition to the diagnostic information extracted. Radiation doses utilized in the course of dental treatment might be low for individual examinations but patients are exposed to repeated examinations very often and many people are exposed during the course of dental care. Therefore, principles of radiation protection and safety are necessary for the dentists to follow to ensure minimum and inevitable exposure. Aim The aim of this study was to investigate the knowledge and behaviour of general dentists practicing in the National Capital Region (NCR) regarding radiation safety during oral radiographic procedures. Materials and Methods The study was a questionnaire based cross-sectional study. A total of 500 general dentists were contacted to participate in the study. The target population entailed of general dentists practicing in the National Capital Region. Data was computed and tabulated in Microsoft excel sheet and statistical analysis was performed with the help of SPSS version 21.0. Results The total response rate recovered was 70.6% and the respondents comprised of 59% and 41% males & females respectively. Only 64.8% of the general dentists contemplated thyroid to be the most important organ for radiation protection. Only 28.8% of the general dentists followed the position & distance rule appropriately. Conclusion The results showed that the knowledge and behaviour of the general dentists and the practices adopted by them regarding radiation safety is not satisfactory. To ensure the following of basic and necessary guidelines for radiation safety and protection, strict rules with penalties should be implemented by the state councils and new and interesting methods of education for this spectrum of the

Background: Electrophysiological studies show that critical illness polyneuromyopathy appears in the early stage of sepsis before the manifestation of clinical findings. The metabolic response observed during sepsis causes glutamine to become a relative essential amino acid. Aims: We aimed to assess the changes in neuromuscular transmission in the early stage of sepsis after glutamine supplementation. Study Design: Animal experimentation. Methods: Twenty male Sprague-Dawley rats were randomized into two groups. Rats in both groups were given normal feeding for one week. In the study group, 1 g/kg/day glutamine was added to normal feeding by feeding tube for one week. Cecal ligation and perforation (CLP) surgery was performed at the end of one week. Before and 24 hours after CLP, compound muscle action potentials were recorded from the gastrocnemius muscle. Results: Latency measurements before and 24 hours after CLP were 0.68±0.05 ms and 0.80±0.09 ms in the control group and 0.69±0.07 ms and 0.73±0.07 ms in the study group (p<0.05). Conclusion: Since enteral glutamine prevented compound muscle action potentials (CMAP) latency prolongation in the early phase of sepsis, it was concluded that enteral glutamine replacement might be promising in the prevention of neuromuscular dysfunction in sepsis; however, further studies are required.

Sepsis was a systemic response to a local infection. Apoptosis was observed in the experimental sepsis. In this study, cecal ligation and puncture (CLP)-induced sepsis was established in rats. We found that sepsis decreased thyroid hormone levels, including triiodothyronine (T3), thyroxine (T4), free T3 (fT3), and free T4 (fT4). Besides, we detected the increasing expression level of Caspase-3 and increasing ratio of TUNEL positive cells in the thyroid after sepsis. Furthermore, a series of pathological ultrastructural changes were observed in thyroid follicular epithelial cells by CLP-induced sepsis. This study established a sepsis animal model and provided the cellular and molecular basis for decoding the pathological mechanism in thyroid with the occurrence of sepsis.

Background Sepsis in the first 3 days of life is a leading cause of morbidity and mortality among infants. Group B Streptococcus (GBS), historically the primary cause of early-onset sepsis, has declined through widespread use of intrapartum chemoprophylaxis. We estimated the national burden of invasive early-onset sepsis (EOS) cases and deaths in the era of GBS prevention. Methods Population-based surveillance for invasive EOS was conducted in 4 of CDC’s Active Bacterial Core surveillance (ABCs) sites from 2005–2008. We calculated incidence using state and national live birth files. Estimates of the national number of cases and deaths were calculated, standardizing by race and gestational age. Results ABCs identified 658 cases of EOS; 72 (10.9%) were fatal. Overall incidence remained stable during the three years (2005:0.77 cases/1,000 live births; 2008:0.76 cases/1,000 live births). GBS (~38%) was the most commonly reported pathogen followed by Escherichia coli (~24%). Black preterm infants had the highest incidence (5.14 cases/1,000 live births) and case fatality (24.4%). Non-black term infants had the lowest incidence (0.40 cases/1,000 live births) and case fatality (1.6%). The estimated national annual burden of EOS was approximately 3,320 cases (95% CI: 3,060–3,580) including 390 deaths (95% CI: 300–490). Among preterm infants, 1,570 cases (95% CI: 1,400–1,770; 47.3% of the overall) and 360 deaths (95% CI: 280–460; 92.3% of the overall) occurred annually. Conclusions The burden of invasive early-onset sepsis remains substantial in the era of GBS prevention and disproportionately affects preterm and black infants. Identification of strategies to prevent preterm births is needed to reduce the neonatal sepsis burden. PMID:21654548

The National Center for Interprofessional Practice and Education, a United States public-private partnership, was formed to provide national leadership, scholarship, evidence, and coordination to advance interprofessional education (IPE) and practice. Many external drivers led to the creation of the partnership that culminated in the National Center: patient safety initiatives, the need for care coordination and transitions efforts, quality improvement imperatives, calls for teamwork and workforce optimization, newly defined national core competencies for interprofessional collaborative practice, practice redesign, escalating health care costs, and state and federal policies. The National Center principals who have served in a variety of senior leadership roles--a clinician, educationalist, and informaticist--recognized the opportunity to leverage the potential that informatics could bring not only to the center but also to the field of IPECP. An informatics approach focuses on collaborative processes and works to address information processing, communications, and data collection. To do so, the National Center created multiple platforms: informatics education, a resource exchange, communication strategy, incubator network, national data repository, and learning system.

Although there has been substantial debate and research concerning the economic impact of neo-liberal practices, there is a paucity of research about the potential relation between neo-liberal economic practices and population health. We assessed the extent to which neo-liberal policies and practices are associated with population health at the national level. We collected data on 119 countries between 1980 and 2004. We measured neo-liberalism using the Fraser Institute's Economic Freedom of the World (EFW) Index, which gives an overall score as well as a score for each of five different aspects of neo-liberal economic practices: (1) size of government, (2) legal structure and security of property rights, (3) access to sound money, (4) freedom to exchange with foreigners and (5) regulation of credit, labor and business. Our measure of population health was under-five mortality. We controlled for potential mediators (income distribution, social capital and openness of political institutions) and confounders (female literacy, total population, rural population, fertility, gross domestic product per capita and time period). In longitudinal multivariable analyses, we found that the EFW index did not have an effect on child mortality but that two of its components: improved security of property rights and access to sound money were associated with lower under-five mortality (p = 0.017 and p = 0.024, respectively). When stratifying the countries by level of income, less regulation of credit, labor and business was associated with lower under-five mortality in high-income countries (p = 0.001). None of the EFW components were significantly associated with under-five mortality in low-income countries. This analysis suggests that the concept of 'neo-liberalism' is not a monolithic entity in its relation to health and that some 'neo-liberal' policies are consistent with improved population health. Further work is needed to corroborate or refute these findings.

Ireland's National Men's Health Policy recommended developing training programmes tailored to the needs of those working in health and allied health professionals and ENGAGE was developed to meet that recommendation. This study evaluated the impact of ENGAGE on frontline service providers' self-reported knowledge, skills, capacity and practice up to 5-months post training. Between 2012 and 2015, ENGAGE Trainers (n = 57) delivered 62 1-day training programmes to 810 participants. This study was conducted on a subset of those training days (n = 26) and participants. Quantitative methodologies were used to collect pre (n = 295), post (n = 295) and 5-month post (n = 128) training questionnaire data. Overall, participants were highly satisfied with the training immediately post training (8.60 ± 1.60 out of 10) and at 5-month follow up (8.06 ± 1.43 out of 10). Participants' self-reported level of knowledge, skill and capacity in identifying priorities, engaging men and influencing practice beyond their own organisation increased immediately following training (P < 0.001) and, with the exception of improving capacity to engage men and influencing practice beyond their organisation, these improvements were sustained at 5-month post training (P < 0.001). The vast majority of service providers (93.4%) reported that ENGAGE had impacted their work practice up to 5-month post training. The findings suggest that ENGAGE has succeeded in improving service providers' capacity to engage and work with men; improving gender competency in the delivery of health and health related services may increase the utilisation of such services by men and thereby improve health outcomes for men.

Sepsis survivors suffer from additional morbidities, including higher risk of readmissions, nervous system disturbances and cognitive dysfunction, and increased mortality, even several years after the initial episode of sepsis. In many ways, the phenotype of sepsis survivors resembles the phenotype associated with accelerated aging. Since telomere shortening is a hallmark of aging, we investigated whether sepsis also leads to telomere shortening. Male balb/c mice were divided into two groups: the control group received 100 μl of normal saline intraperitoneally (i.p.) and the sepsis group received 15 mg/kg of bacterial lipopolysaccharide i.p. After 48 h, animals were euthanized to collect blood, spleen and kidney. The human component of our study utilized blood samples obtained from patients in the trauma department and samples collected 7 d later in those patients who developed sepsis. Telomere length was measured by quantitative polymerase chain reaction. Since oxidative stress is a known inducer of telomere shortening, thiobarbituric acid–reactive substances and superoxide dismutase activity were analyzed to evaluate oxidative stress burden. Induction of endotoxemia in mice resulted in significant telomere shortening in spleen and kidney. Blood cells from patients who progressed to sepsis also exhibited a statistically significant reduction of telomere length. Endotoxemia in mice also induced an early-onset increase in oxidative stress markers but was not associated with a downregulation of telomerase protein expression. We conclude that endotoxemia and sepsis induce telomere shortening in various tissues and hypothesize that this may contribute to the pathogenesis of the delayed pathophysiological events in sepsis survivors.

Sepsis remains a leading cause of mortality among neonates, especially in developing countries. Most cases of neonatal sepsis are attributed to Escherichia coli and other members of the Enterobacteriaceae family. Shewanella algae (S. algae) is a gram-negative saprophytic bacillus, commonly associated with the marine environment, which has been isolated from humans. Early onset neonatal sepsis caused by S. algae is uncommon. We report a case of S. algae blood stream infection in a newborn with early onset neonatal sepsis.
Although sepsis is a systemic process, the pathophysiological cascade of events may vary from region to region. Abdominal sepsis represents the host’s systemic inflammatory response to bacterial peritonitis. It is associated with significant morbidity and mortality rates, and is the second most common cause of sepsis-related mortality in the intensive care unit. The review focuses on sepsis in the specific setting of severe peritonitis. PMID:24674057

The nociceptin system comprises the nociceptin receptor (NOP) and the ligand nociceptin/orphanin FQ (N/OFQ) that binds to the receptor. The archetypal role of the system is in pain processing but the NOP receptor is also expressed on immune cells. Activation of the NOP receptor is known to modulate inflammatory responses, such as mast-cell degranulation, neutrophil rolling, vasodilation, increased vascular permeability, adhesion molecule regulation and leucocyte recruitment. As there is a loss of regulation of inflammatory responses during sepsis, the nociceptin system could be a target for therapies aimed at modulating sepsis. This review details the known effects of NOP activation on leucocytes and the vascular endothelium and discusses the most recent human and animal data on the role of the nociceptin system in sepsis.

Sepsis-related organ dysfunction remains the most common cause of death in the intensive care unit (ICU), despite advances in healthcare and science. Marked oxidative stress as a result of the inflammatory responses inherent with sepsis initiates changes in mitochondrial function which may result in organ damage. Normally, a complex system of interacting antioxidant defences is able to combat oxidative stress and prevents damage to mitochondria. Despite the accepted role that oxidative stress-mediated injury plays in the development of organ failure, there is still little conclusive evidence of any beneficial effect of systemic antioxidant supplementation in patients with sepsis and organ dysfunction. It has been suggested, however, that antioxidant therapy delivered specifically to mitochondria may be useful.

Evidence-based guidelines for recognizing and treating sepsis have been available for decades, yet healthcare providers do not adhere to the recommendations. Sepsis can progress rapidly if not recognized early. Literature reports reveal that sepsis is the leading cause of death in non-cardiac intensive care units (ICUs), and it is one of the most…

Sepsis is a systemic inflammatory response to severe infection causing significant morbidity and mortality that costs the health care system $20.3 billion annually within the United States. It is well established that fluid resuscitation is a central component of sepsis management; however, to date there is no consensus as to the ideal composition of fluid used for resuscitation. In this review, we discuss the progression of clinical research comparing various fluids, as well as the historical background behind fluid selection for volume resuscitation. We conclude that the use of balanced fluids, such as Ringer’s Lactate, seems very promising but further research is needed to confirm their role. PMID:27081589

Over the past 9 years, ten patients have presented to the Thoracic Unit, Glasgow Royal Infirmary, with 12 empyemas secondary to intra-abdominal sepsis. In eight patients, the presenting signs and symptoms were wrongly attributed to primary intra-thoracic pathology. All were subsequently found to have intra-abdominal sepsis. The presence of empyema after recent abdominal surgery or abdominal pain strongly suggests a diagnosis of ipsilateral subphrenic abscess. Adequate surgical drainage is essential. In our experience, limited thoracotomy with subdiaphragmatic extension offers the best access to both pleural and subphrenic spaces and provides the greatest chance of eradicating infection on both sides of the diaphragm.

Sepsis and septic shock are a continuum of disease resulting from a complex host response to infection. They are major health issues in the United States, causing significant financial burden to the health care system in addition to multisystem morbidity and high rates of mortality. In recent decades, landmark trials in sepsis management have demonstrated improved mortality. Although the value of protocol-driven care is currently under question, it is clear that early recognition, prompt resuscitation, and timely use of antibiotics are of utmost importance.

Our evolving understanding of the physiologic processes that lead to sepsis has led to updated consensus guidelines outlining priorities in the recognition and treatment of septic patients. However, an enormous question remains when considering how to best implement these guidelines in settings with limited resources, which include rural US emergency departments and low- and middle-income countries. The core principles of sepsis management should be a priority in community emergency departments. Similarly, cost-effective interventions are key priorities in low- and middle-income countries; however, consideration must be given to the unique challenges associated with such settings.

The Medical Quality Improvement Consortium (MQIC) is a nationwide collaboration of 74 healthcare delivery systems, consisting of 3755 clinicians, who contribute de-identified clinical data from the same commercial electronic medical record (EMR) for quality reporting, outcomes research and clinical research in public health and practice benchmarking. Despite the existence of a common, centrally-managed, shared terminology for core concepts (medications, problem lists, observation names), a substantial "back-end" information management process is required to ensure terminology and data harmonization for creating multi-facility clinically-acceptable queries and comparable results. We describe the information architecture created to support terminology harmonization across this data-sharing consortium and discuss the implications for large scale data sharing envisioned by proponents for the national adoption of ambulatory EMR systems.

In order to generate the gains that can come from analysing and linking big datasets, data holders need to consider the ethical frameworks, principles and applications that help to maintain public trust. In the USA, the National Science Foundation helped to set up a Council for Big Data, Ethics and Society, of which there is no equivalent in the UK. In November 2015, the Royal Statistical Society convened a workshop of 28 participants from government, academia and the private sector, and discussed the practical priorities that might be assisted by a new Council of Data Ethics in the UK. This article draws together the views from that meeting. Priorities for policy-makers and others include seeking a public mandate and informing the terms of the social contract for use of data; building professional competence and due diligence on data protection; appointment of champions who are competent to address public concerns; and transparency, across all dimensions. For government data, further priorities include improvements to data access, and development of data infrastructure. In conclusion, we support the establishment of a national Data Ethics Council, alongside wider and deeper engagement of the public to address data ethics dilemmas.This article is part of the themed issue 'The ethical impact of data science'.

Variable biospecimen collection, processing, and storage practices may introduce variability in biospecimen quality and analytical results. This risk can be minimized within a facility through the use of standardized procedures; however, analysis of biospecimens from different facilities may be confounded by differences in procedures and inferred biospecimen quality. Thus, a global approach to standardization of biospecimen handling procedures and their validation is needed. Here we present the first in a series of procedural guidelines that were developed and annotated with published findings in the field of human biospecimen science. The series of documents will be known as NCI Biospecimen Evidence-Based Practices, or BEBPs. Pertinent literature was identified via the National Cancer Institute (NCI) Biospecimen Research Database ( brd.nci.nih.gov ) and findings were organized by specific biospecimen pre-analytical factors and analytes of interest (DNA, RNA, protein, morphology). Meta-analysis results were presented as annotated summaries, which highlight concordant and discordant findings and the threshold and magnitude of effects when applicable. The detailed and adaptable format of the document is intended to support the development and execution of evidence-based standard operating procedures (SOPs) for human biospecimen collection, processing, and storage operations.

Sepsis is a major cause of neonatal morbidity and mortality, especially in vulnerable preterm populations. Immature immune defenses, and environmental and maternal factors contribute to this risk, with as many as a third of very preterm infants experiencing sepsis during their stay in the neonatal intensive care unit (NICU). Epidemiologic and twin studies have suggested that there is a genetic contribution to sepsis predilection. Several investigators have conducted candidate gene association studies on variants of specific interest and potential functional significance in neonatal sepsis. In this review, we describe details of studies that have evaluated genetic susceptibility in neonatal sepsis, and summarize findings from a review of candidate gene association studies.

Rationale: Limited data exist about the international burden of severe sepsis in critically ill children. Objectives: To characterize the global prevalence, therapies, and outcomes of severe sepsis in pediatric intensive care units to better inform interventional trials. Methods: A point prevalence study was conducted on 5 days throughout 2013–2014 at 128 sites in 26 countries. Patients younger than 18 years of age with severe sepsis as defined by consensus criteria were included. Outcomes were severe sepsis point prevalence, therapies used, new or progressive multiorgan dysfunction, ventilator- and vasoactive-free days at Day 28, functional status, and mortality. Measurements and Main Results: Of 6,925 patients screened, 569 had severe sepsis (prevalence, 8.2%; 95% confidence interval, 7.6–8.9%). The patients’ median age was 3.0 (interquartile range [IQR], 0.7–11.0) years. The most frequent sites of infection were respiratory (40%) and bloodstream (19%). Common therapies included mechanical ventilation (74% of patients), vasoactive infusions (55%), and corticosteroids (45%). Hospital mortality was 25% and did not differ by age or between developed and resource-limited countries. Median ventilator-free days were 16 (IQR, 0–25), and vasoactive-free days were 23 (IQR, 12–28). Sixty-seven percent of patients had multiorgan dysfunction at sepsis recognition, with 30% subsequently developing new or progressive multiorgan dysfunction. Among survivors, 17% developed at least moderate disability. Sample sizes needed to detect a 5–10% absolute risk reduction in outcomes within interventional trials are estimated between 165 and 1,437 patients per group. Conclusions: Pediatric severe sepsis remains a burdensome public health problem, with prevalence, morbidity, and mortality rates similar to those reported in critically ill adult populations. International clinical trials targeting children with severe sepsis are warranted. PMID:25734408
The innate immune response is the first line of defense against infection. Toll-like receptors (TLRs) recognize bacterial lipopolysaccharide and other pathogen-associated molecular patterns (PAMPs). Intracellular signals initiated by interaction between Toll receptors and specific PAMPs results in inflammatory response. Sepsis and septic shock are the result of an exaggerated inflammatory systemic response induced by innate immune dysregulation.

Critical illness is characterized by oxidative stress which leads to multiple organ failure, and sepsis-related organ dysfunction remains the most common cause of death in the intensive care unit. Over the last 2 decades, different antioxidant therapies have been developed to improve outcomes in septic patients. According to recent evidence, selenium therapy should be considered the cornerstone of the antioxidant strategies. Selenium given as selenious acid or sodium selenite should be considered as a drug or pharmaconutrient with prooxidant and cytotoxic effects when a loading dose in intravenous bolus form is administered, particularly in the early stage of severe sepsis/septic shock. To date, several phase ii trials have demonstrated that selenium therapy may be able to decrease mortality, improve organ dysfunction and reduce infections in critically ill septic patients. The effect of selenium therapy in sepsis syndrome must be confirmed by large, well designed phase iii clinical trials. The purpose of this review is to discuss current evidence on selenium pharmaconutrition in sepsis syndrome.

Sepsis is a severe critical illness syndrome that arises from infectious insults. While the host immune system is generally beneficial, an overshooting and unregulated immune response can cause serious organ tissue injury. During sepsis, systemic hypotension, disturbed perfusion of the microcirculation, and direct tissue-toxicity caused by inflammatory immune reaction can occur and contribute to organ failure. The failure of two or more vital organ systems is termed multi-organ dysfunction syndrome (MODS) and resembles a very critical condition associated with high morbidity and mortality. Importantly, no specific treatment strategy exists to efficiently prevent the development of MODS during sepsis. In this review, we aim to identify the relevant molecular immunological pathways involved in the pathogenesis of MODS during sepsis. We believe that a detailed understanding of this mechanism is necessary for the development of new treatment approaches for septic patients. In particular, knowledge of the endogenous regulators keeping the balance between necessary immune system activation to combat infections and prevention of host tissue damage would greatly improve the chances for the development of effective interventions.

This article describes an innovative approach to enhancing the capacity of advanced practice clinicians (APCs) in a large faith-based health system consisting of multiple markets across the United States. With the challenges in health care today, promotion of advanced practice is vital to increasing quality and access to care while maintaining cost-effectiveness. The development of a national Advanced Practice Leadership Council led by the Vice President of Advanced Practice at Catholic Health Initiatives has been a progressive approach in mitigating the challenges facing APCs in today's health care arena. The success of the Council has led to its inclusion on the health system's national clinical governance structure. The authors discuss development of the Council along with specific information regarding various committee work, including APC state regulations, delineation of privileges, quality measures, and total compensation.

As neonatal sepsis is a severe condition, there is a call for reliable biomarkers to differentiate between infected and noninfected newborns. Although blood culture has been considered as the gold standard, this analysis is still too slow and limited by false negative results. Use of CRP is hampered by a physiological 3-day increase, resulting in a low sensitivity to detect sepsis at an early stage. A moderate diagnostic accuracy of other acute phase proteins has been demonstrated (serum amyloid A, procalcitonin, lipopolysaccharide binding protein, mannose binding lectin and hepcidin). In neonatal sepsis, changed chemokine/cytokine levels are observed before those of acute phase reactants. High IL-6, IL-8, IL-10 and TNF-α concentrations are detected in infected infants. Soluble interleukin-2 receptor has been used to identify bacteremia, whereas low plasma RANTES concentrations are characteristic for septicemia. Several cell adhesion molecules contribute to the pathogenesis of sepsis. As an upregulated CD64 expression on granulocytes is found within 1-6h after bacterial invasion, serial CD64 measurements could guide antibiotic therapy. An increased CD11b/CD18 density can improve the diagnosis, and a positive correlation between CD11b and the severity of systemic inflammation has been reported. An early increase in sCD14-ST presepsin is also observed during sepsis, whereas high sTREM-1 values in early-onset neonatal sepsis (EOS) have been associated with mortality. Biomarkers resulting from proteomics are also promising. A 4-biomarker 'mass restricted' score has been validated as diagnostic for intra-amniotic infection and/or inflammation. S100A8 in amniotic fluid is a strong predictor of an increased incidence of EOS. Proteomic analysis of cord blood has revealed altered protein expression patterns. The ApoSAA score is useful for identifying sepsis and could guide prescription of antibiotics. (1)H-NMR and GC-MS metabolomics allow to diagnose septic shock, which is

Severe sepsis, septic shock, and related inflammatory syndromes are driven by the aberrant expression of proinflammatory mediators by immune cells. During the acute phase of sepsis, overexpression of chemokines and cytokines drives physiological stress leading to organ failure and mortality. Following recovery from sepsis, the immune system exhibits profound immunosuppression, evidenced by an inability to produce the same proinflammatory mediators that are required for normal responses to infectious microorganisms. Gene expression in inflammatory responses is influenced by the transcriptional accessibility of the chromatin, with histone posttranslational modifications determining whether inflammatory gene loci are set to transcriptionally active, repressed, or poised states. Experimental evidence indicates that histone modifications play a central role in governing the cytokine storm of severe sepsis, and that aberrant chromatin modifications induced during the acute phase of sepsis may mediate chronic immunosuppression in sepsis survivors. This review will focus on the role of histone modifications in governing immune responses in severe sepsis, with an emphasis on specific leukocyte subsets and the histone modifications observed in these cells during chronic stages of sepsis. Additionally, the expression and function of chromatin-modifying enzymes (CMEs) will be discussed in the context of severe sepsis, as potential mediators of epigenetic regulation of gene expression in sepsis responses. In summary, this review will argue for the use of chromatin modifications and CME expression in leukocytes as potential biomarkers of immunosuppression in patients with severe sepsis.
Objectives. The objective of this study is to explore the current knowledge, attitude, and practice of family physicians working in family medicine clinics in National Guard Health Affairs (NGHA), Riyadh, toward colorectal cancer (CRC) screening and to identify the barriers of the screening. Methods. Data were collected using a validated self-administered questionnaire adopted from the National Cancer Institute in USA, customized by adding and eliminating questions to be in line with the institution (NGHA) characteristics. Results. Of the 130 physicians, 56.2% of the physicians were not practicing CRC screening although 94.6% considered CRC screening effective. Board certified physicians had higher knowledge score and were practicing CRC screening more when compared to other physicians. Physicians who reported practicing CRC screening scored more on the knowledge score than those not practicing. Male physicians scored better on attitude score than female physicians. The study found that barriers were cited in higher rates among physicians not practicing CRC screening compared with practicing physicians. Lack of patients' awareness was the most cited barrier. Conclusion. Large percentage of family physicians in this study do not practice CRC screening, despite the knowledge level and the positive attitude. PMID:25328703

With the advent of antibiotic resistance, pathogenic bacteria have become a major threat in cases of neonatal sepsis; however, guidelines for treatment have not yet been standardized. In this study, 15 cases of neonatal Streptococcus agalactiae sepsis from our hospital were retrospectively analyzed. Of these, nine cases showed early-onset and six cases showed late-onset sepsis. Pathogens were characterized by genotyping and antibiotic sensitivity tests on blood cultures. Results demonstrated that in cases with early-onset sepsis, clinical manifestations affected mainly the respiratory tract, while late-onset sepsis was accompanied by intracranial infection. Therefore, we suggest including a cerebrospinal fluid examination when diagnosing neonatal sepsis. Bacterial genotyping indicated the bacteria were mainly type Ib, Ia, and III S. agalactiae. We recommend treatment with penicillin or ampicillin, since bacteria were resistant to clindamycin and tetracycline. In conclusion, our results provide valuable information for the clinical treatment of S. agalactiae sepsis in neonatal infants.

Neonatal sepsis is one of the most fulminating conditions in neonatal intensive care units. Antipathogen and supportive care are administered routinely, but do not deliver satisfactory results. In addition, the efforts to treat neonatal sepsis with anti-inflammatory agents have generally shown to be futile. The accumulating data imply that intracellular redox changes intertwined into neonatal sepsis redox cycle represent the main cause of dysfunction of mitochondria and cells in neonatal sepsis. Our aim here is to support the new philosophy in neonatal sepsis treatment, which involves the integration of mechanisms that are responsible for cellular dysfunction and organ failure, the recognition of the most important targets, and the selection of safe agents that can stop the neonatal sepsis redox cycle by hitting the hot spots. Redox-active agents that could be beneficial for neonatal sepsis treatment according to these criteria include lactoferrin, interleukin 10, zinc and selenium supplements, ibuprofen, edaravone, and pentoxifylline.

Through a literature review, the epidemiology and pathophysiology, including alterations in inflammation, coagulation, and impaired fibrinolysis that occur in the course of severe sepsis, is presented. Treatment guidelines that are evidence-based and endorsed by 11 professional societies representing multispecialty groups are described. Severe sepsis is common; 750,000 cases are estimated to occur annually in the United States. The mortality rate for severe sepsis still ranges from 30 to 50%, and is as high as 80 to 90% for septic shock and multiple organ dysfunction. Severe sepsis exists along a continuum initiated by a localized infection that triggers a systemic response. A cascade of inflammation and activation of the coagulation system associated with impaired fibrinolysis leads to alterations in microvascular circulation associated with organ dysfunction, severe sepsis, multiple organ dysfunction syndrome, and death. In an attempt to improve care and reduce mortality, the Surviving Sepsis Campaign and The Institute for Healthcare Improvement (IHI) have created two sepsis treatment bundles.

Sepsis contributes to up to half of all deaths in hospitalized patients, and early interventions, such as appropriate antibiotics, have been shown to improve outcomes. Most research has focused on early identification and treatment of patients with sepsis in the ED and the ICU; however, many patients acquire sepsis on the general wards. The goal of this review is to discuss recent advances in the detection of sepsis in patients on the hospital wards. We discuss data highlighting the benefits and limitations of the systemic inflammatory response syndrome (SIRS) criteria for screening patients with sepsis, such as its low specificity, as well as newly described scoring systems, including the proposed role of the quick sepsis-related organ failure assessment (qSOFA) score. Challenges specific to detecting sepsis on the wards are discussed, and future directions that use big data approaches and automated alert systems are highlighted.

Despite improvements in resuscitation and treatment of sepsis, the morbidity and mortality remain unacceptably high. Microvascular dysfunction has been shown to play a significant role in the pathogenesis of sepsis and is a potential new target in the management of sepsis. Clinical studies, aided by new techniques that allow for real-time assessment of the microcirculation, have shown that disturbances in microcirculatory flow are common in sepsis and correlate with worse outcomes. Bedside measurement of microcirculatory perfusion has become simpler and more accessible, and may provide key insights into prognosis in sepsis and guide future therapeutics, much like mean arterial pressure (MAP), lactate, and mixed central oxygen saturation (SvO(2)) do now. The authors review here the role of microcirculatory dysfunction in sepsis and its potential role as a therapeutic target in sepsis.

Despite some recent success with clinical trials studying innovative therapies in sepsis, the field remains predominantly one of failure despite compounds with significant preclinical activity. Preclinical animal experimentation remains an important component of drug development, and a portfolio approach is recommended. Failure in animals is more likely to predict failure in humans; however, success in animals often does not predict success in humans. Because the signal with innovative therapy of sepsis is likely to be low, an oncology model clinical trial approach, in which studies start with a high-risk homogeneous population and look for a large treatment effect with smaller numbers of patients, is likely to be more relevant than the commonly used cardiology model, in which studies search for a small treatment effect using large, heterogeneous, low-risk populations. With certain rules in place, improvement in organ function may be a worthwhile alternative to mortality as a clinical end point. Once a therapy is approved, adopting less stringent but still appropriate criteria for the use of that therapy in clinical practice may be appropriate.

IMPORTANCE Definitions of sepsis and septic shock were last revised in 2001. Considerable advances have since been made into the pathobiology (changes in organ function, morphology, cell biology, biochemistry, immunology, and circulation), management, and epidemiology of sepsis, suggesting the need for reexamination. OBJECTIVE To evaluate and, as needed, update definitions for sepsis and septic shock. PROCESS A task force (n = 19) with expertise in sepsis pathobiology, clinical trials, and epidemiology was convened by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. Definitions and clinical criteria were generated through meetings, Delphi processes, analysis of electronic health record databases, and voting, followed by circulation to international professional societies, requesting peer review and endorsement (by 31 societies listed in the Acknowledgment). KEY FINDINGS FROMEVIDENCE SYNTHESIS Limitations of previous definitions included an excessive focus on inflammation, the misleading model that sepsis follows a continuum through severe sepsis to shock, and inadequate specificity and sensitivity of the systemic inflammatory response syndrome (SIRS) criteria. Multiple definitions and terminologies are currently in use for sepsis, septic shock, and organ dysfunction, leading to discrepancies in reported incidence and observed mortality. The task force concluded the term severe sepsis was redundant. RECOMMENDATIONS Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. For clinical operationalization, organ dysfunction can be represented by an increase in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score of 2 points or more, which is associated with an in-hospital mortality greater than 10%. Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a

Background: There is currently a resurgence of interest in interprofessional education and collaborative practice (IPECP) and its potential to positively impact health outcomes at both the patient level and population level, healthcare delivery, and health professions education. This resurgence of interest led to the creation of the National Center on Interprofessional Collaborative Practice and Education in October 2012. Methods: This paper describes three intertwined knowledge generation strategies of the National Center on Interprofessional Practice and Education: (1) the development of a Nexus Incubator Network, (2) the undertaking of comparative effectiveness research, and (3) the creation of a National Center Data Repository. Results: As these strategies are implemented over time they will result in the production of empirically grounded knowledge regarding the direction and scope of the impact, if any, of IPECP on well-defined health and healthcare outcomes including the possible improvement of the patient experience of care. Conclusions: Among the motivating factors for the National Center and the three strategies adopted and addressed herein is the need for rigorously produced, scientifically sound evidence regarding IPECP and whether or not it has the capacity to positively affect the patient experience of care, the health of populations, and the per capita cost of healthcare.

Immune dysfunction is the main characteristic of sepsis. T cell Ig and mucin domain protein 3 (Tim-3) on the monocytes has been reported to promote immune homeostasis during sepsis, but the influences of plasm soluble Tim-3 (sTim-3) on the immune system during sepsis remain unknown. Here, 100 patients with different severities of sepsis (40 sepsis, 42 severe sepsis, and 18 septic shock) were enrolled in this study. The Tim-3 and human leukocyte antigen-DR (HLA-DR) on the circulating monocytes were detected using flow cytometry. Plasma sTim-3 was detected by enzyme-linked immunosorbent assay. Inflammatory factors and two kinds of A disintegrin and metalloprotease (ADAM) - ADAM10 and ADAM17 were assessed. The Tim-3 and HLA-DR on the monocytes decreased with increasing sepsis severity. The sTim-3 was reduced in the sepsis and severe sepsis patients but was elevated in the septic shock patients who exhibited significant immunosuppression as predicted by HLA-DR. sTim-3 levels were negatively correlated with IL-12 and TNF-α. ADAM10 and ADAM17, sheddases of Tim-3, exhibited trends toward elevations in the septic shock group. In conclusion, sTim-3 was involved in the development of sepsis. The homeostasis-promoting role of the Tim-3 on the monocytes was disrupted, while the inhibitory role of sTim-3 emerged during sepsis-induced immunosuppression.

Circulating lymphocyte number was significantly decreased in patients with sepsis. However, it remains unknown which severity phase (sepsis, severe sepsis, and septic shock) does it develop and what happen on each subpopulation. Eight patients with differing severities of sepsis (31 sepses, 33 severe sepses, and 16 septic shocks) were enrolled. Quantitative real-time polymerase chain reaction (RT-PCR) of Th1, Th2, and Th17; regulatory T (Treg) cell-specific transcription factor T-bet; GATA-3; RORgammat (RORγt); forkhead box P3 (FOXP3); and IL-17 mRNA were performed, and the enzyme-linked immunosorbent assay (ELISA) was used to detect serum interferon (IFN)-γ, IL-4, and IL-10. In this study, the Th1, Th2, Treg transcription factors, and related cytokines IFN-γ, IL-4, and IL-10 levels of sepsis and severe sepsis patients in peripheral blood were significantly higher than those of the normal controls. Except for IL-17, the T-bet, GATA-3, and IFN-γ levels of septic shock patients were lower than those of sepsis patients. We also observed that the proportions of Th17/Treg in the sepsis and septic shock groups were inversed. From the above, the inflammatory response especially the adaptive immune response is still activated in sepsis and severe sepsis, but significant immunosuppression was developed in septic shock. In addition, the proportion of Th17/Treg inversed may be associated with the illness aggravation of patients with sepsis.
Natural science investigators at the end of the eighteenth century made use of conflicting labels to position their respective preferred fields of activity in the Earth sciences. This mania for labelling marked their break with natural science and the umbrella term 'mineralogy'. In this conflict situation of specialist classifications and explanations, two terms in particular were established: geognosy and geology, which covered the very promising project of research in the areas of the 'origin of the Earth' and the 'formation of the Earth'. These and the associated research goals were subsequently accorded a dazzling career. Proceeding from the conceptual core-meaning in the formation of terms und its semantic spectrum and conceptual shifts in a time of change, my study will look at the identity and heterogeneity functions of geology and geognosy. For whereas in French and English speaking countries the term geology came to be used exclusively (geology, géologie), this was avoided in German, particularly because the term geognosy was preferred. These national differences may be explained with reference to the different cultural and national styles of science: for example the social embedding of geology in the culture of the English gentleman or the French museum culture, and the close connection of 'German' geognosy to mining. A further starting point in the analysis of the double use of both geology and geognosy in German speaking countries until 1840 is provided by the different references to temporalization and spatialization of the two terms. And we should also include the practical implications and the epistemic requirements that were bound up with the defence of geognosy in the German speaking world.

Tuberculosis (TB) primarily occurs in the foreign-born in European countries, such as the UK, where increasing notifications and the high proportion of foreign-born cases has refocused attention on immigrant (new entrant) screening. We investigated how UK primary care organisations (PCOs) screen new entrants and whether this differs according to TB burden in the PCOs (incidence < 20 or ≥ 20 cases per 100,000 per annum). An anonymous, 20-point questionnaire was sent to all 192 UK PCOs asking which new entrants are screened, who is screened for active TB/latent TB infection (LTBI) and the methods used. Descriptive analyses were undertaken. Categorical responses were compared using the Chi-squared test. 177 (92.2%) out of 192 PCOs responded; all undertook screening action in response to abnormal chest radiographs, but only 107 (60.4%) screened new entrants for LTBI. Few new entrants had active TB diagnosed (median 0.0%, interquartile range (IQR) 0.0-0.5%) but more were identified with LTBI (median 7.85%, IQR 4.30-13.50%). High-burden PCOs were significantly less likely to screen new entrants for LTBI (OR 0.26, 95% CI 0.12-0.54; p<0.0001). Among PCOs screening for LTBI, there was substantial deviation from national guidance in selection of new entrant subgroups and screening method. Considerable heterogeneity and deviation from national guidance exist throughout the UK new entrant screening process, with high-burden regions undertaking the least screening. Forming an accurate picture of current front-line practice will help to inform future development of European new entrant screening policy.

Background Pancreatic ductal adenocarcinoma (PDAC) remains one of the most deadly cancers in Europe and the USA. There is consensus that radical tumor surgery is the only viable option for any long-term survival in patients with PDAC. So far, limited data are available regarding the routine surgical management of patients with advanced PDAC in the light of surgical guidelines. Methods A national survey on perioperative management of patients with PDAC and currently applied criteria on their tumor resectability in German university and community hospitals was carried out. Results With a response rate of 81.6% (231/283) a total of 95 (41.1%) participating departments practicing pancreatic surgery in Germany are certified as competence and reference centers for surgical diseases of the pancreas in 2016. More than 95% of them indicate to carry out structured and interdisciplinary therapies along with an interdisciplinary pre- and postoperative tumor board. The majority of survey respondents prefer the pylorus-preserving partial pancreatoduodenectomy (93.1%) with standard lymphadenectomy for cancer of the pancreatic head. Intraoperative histological evaluation of the resection margins is used regularly by 99% of the survey respondents. 98.7% of survey respondents carry out partial or complete vein resection, 126 respondents (54.5%) would resect tumor adjacent arteries, and 102 respondents (44.2%) would perform metastasectomy if complete PDAC resection (R0) is possible. Conclusion Evidence-based and standardized pancreatic surgery is practiced by a large number of hospitals in Germany. However, a significant number of survey respondents support an extended radical tumor resection in patients with advanced PDAC even when not indicated by current clinical guidelines. PMID:28267771
In pursuit of such missions as Apollo, the National Aeronautics and Space Administration has called into being unique equipment that obviously has little direct application beyond the achievement of mission objectives. Yet, to assume that further direct application of space program hardware is somehow a measure of the industrial benefits accruing to the nation is to misunderstand how the creation of new technology affects modern industrial capability. This document presents a profile of the significant ways in which technological developments in response to aerospace mission requirements have been coupled into industrial practice, with the result being that improved products and processes are now being utilized to benefit the nation.

The purpose of the Sandia National Laboratories (SNL) Advanced Simulation and Computing (ASC) Software Quality Plan is to clearly identify the practices that are the basis for continually improving the quality of ASC software products. Quality is defined in the US Department of Energy/National Nuclear Security Agency (DOE/NNSA) Quality Criteria, Revision 10 (QC-1) as 'conformance to customer requirements and expectations'. This quality plan defines the SNL ASC Program software quality engineering (SQE) practices and provides a mapping of these practices to the SNL Corporate Process Requirement (CPR) 001.3.6; 'Corporate Software Engineering Excellence'. This plan also identifies ASC management's and the software project teams responsibilities in implementing the software quality practices and in assessing progress towards achieving their software quality goals. This SNL ASC Software Quality Plan establishes the signatories commitments to improving software products by applying cost-effective SQE practices. This plan enumerates the SQE practices that comprise the development of SNL ASC's software products and explains the project teams opportunities for tailoring and implementing the practices.

Through promotion of consistent, evidence-based policy and practice, best practice recommendations can improve service delivery. Nationally relevant best practice recommendations, including guidance for programmes that provide service to people who use drugs, are often created and disseminated by government departments or other national organisations. However, funding priorities do not always align with stakeholder- and community-identified needs for such recommendations, particularly in the case of harm reduction. We achieved success in developing and widely disseminating best practice documents for Canadian harm reduction programmes by bringing together a multi-stakeholder, cross-regional team of people with relevant and diverse experience and expertise. In this commentary, we summarise key elements of our experience to contribute to the literature more detailed and transparent dialogue about team processes that hold much promise for developing best practice resources. We describe our project's community-based principles and process of working together (e.g., regularly scheduled teleconferences to overcome geographic distance and facilitate engagement), and integrate post-project insights shared by our team members. Although we missed some opportunities for power-sharing with our community partners, overall team members expressed that the project offered them valuable opportunities to learn from each other. We aim to provide practical considerations for researchers, other stakeholders, and community members who are planning or already engaged in a process of developing best practice recommendations for programmes and interventions that address drug use.
The field of regenerative medicine has been revolutionized by breakthroughs in stem cell biology, gene engineering, and whole-genome sequencing. These advances are not only scientific or medical but have also advanced how we conceptualize regenerative medicine. The progenitive research that proceeded as well as a substantial part of the funding that supported these discoveries were provided by the National Institutes of Health (NIH). Now, perhaps more than ever, the NIH has a vital role to play in the translation of science into clinical practice. The NIH is uniquely positioned to coordinate interactions between the different institutes and other arms of the government, as well as international organizations. Efforts of researchers in the United States both within and without the NIH are supported by a number of mechanisms, including specialized workshops, and the support of developing small-scale industry. Additionally, the NIH has stepped up to provide necessary infrastructure in areas of regenerative medicine where the medical need might be apparent but might be currently infeasible or unattractive to private-sector investment. This article will discuss these perhaps lesser-known activities of the NIH, which I believe have continued and will continue to contribute to the role of stem cell research in translating science into regenerative medicine.
It is a great time for prevention. As the United States explores what health in our country should look like, it is an extraordinary time to highlight the role of prevention in improving health, saving lives, and saving money. The Affordable Care Act's investment in prevention has spurred innovation by communities and states to keep people healthy and safein the first place This includes growing awareness that community conditions are critical in determining health and that there is now a strong track record of prevention success. Community prevention strategies create lasting changes by addressing specific policies and practices in the environments and institutions that shape our lives and our health-from schools and workplaces to neighborhoods and government. Action at the community level also fosters health equity-the opportunity for every person to achieve optimal health regardless of identity, neighborhood, ability, or social status-and is often the impetus for national-level decisions that vitally shape the well-being of individuals and populations.
A national survey of over 300 commercial design architects was conducted to develop baseline information on their knowledge, perceptions, and use of daylighting in commercial building designs. Pacific Northwest Laboratory conducted the survey for the US Department of Energy's (DOE) Office of Building and Community Systems (BCS). In the survey daylighting was defined as the intentional use of natural light as a partial substitute for artificially generated light. The results suggested that architects need to be educated about the true benefits of daylighting and the impacts it can have on a building's energy performance. Educational programs that will increase the architects' understanding and awareness of modern daylighting technologies and practices should be developed by utilities, stage agencies, and the federal government. If more architects can be made aware of the true effectiveness and positive attributes of daylighting systems and technologies, daylighting may be used in more commercial buildings. The results of the survey show that the more familiar architects feel they are with daylighting, the more they use daylighting. 3 refs., 19 tabs.

A representative national sample of bachelor's-degree nurse educators (N = 697) were surveyed about the seven professional values identified by the American Association of Colleges of Nursing (1986) in Essentials of College and University Education for Professional Nursing. Participants agreed that these values were representative of values nurses need to use in practice, and that educational opportunities related to these values should be included in the curriculum. Eighty-six per cent of the sample perceived that they included some or all of these values predominantly through the informal lesson plan. Esthetics was the most frequently mentioned value that was not considered in any form in the nursing curriculum. Nurse educators teaching at religious-affiliated institutions, and those who had educational preparation in values, already included these values in their formal teaching (P less than .04 and P less than .0001, respectively) and they had discussions about including them differently in the future more frequently (P less than .005 and P less than .006) than did other educators. Faculty members teaching at religious-affiliated institutions also established more plans for including these values within the curriculum than those who taught at public institutions (P less than .0004). One conclusion from this study was that values may continue to be treated differently than other nursing education content, ie, predominantly through the informal lesson plan.

Abstract Understanding the impact that interprofessional education and collaborative practice (IPECP) might have on triple aim patient outcomes is of high interest to health care providers, educators, administrators, and policy makers. Before the work undertaken by the National Center for Interprofessional Practice and Education at the University of Minnesota, no standard mechanism to acquire and report outcome data related to interprofessional education and collaborative practice and its effect on triple aim outcomes existed. This article describes the development and adoption of the National Center Data Repository (NCDR) designed to capture data related to IPECP processes and outcomes to support analyses of the relationship of IPECP on the Triple Aim. The data collection methods, web-based survey design and implementation process are discussed. The implications of this informatics work to the field of IPECP and health care quality and safety include creating standardized capacity to describe interprofessional practice and measure outcomes connecting interprofessional education and collaborative practice to the triple aim within and across sites/settings, leveraging an accessible data collection process using user friendly web-based survey design to support large data scholarship and instrument testing, and establishing standardized data elements and variables that can potentially lead to enhancements to national/international information system and academic accreditation standards to further team-based, interprofessional, collaborative research in the field.

Objective To establish the incidence and aetiology of infectious intestinal disease in the community and presenting to general practitioners. Comparison with incidence and aetiology of cases reaching national laboratory based surveillance. Design Population based community cohort incidence study, general practice based incidence studies, and case linkage to national laboratory surveillance. Setting 70 general practices throughout England. Participants 459 975 patients served by the practices. Community surveillance of 9776 randomly selected patients. Main outcome measures Incidence of infectious intestinal disease in community and reported to general practice. Results 781 cases were identified in the community cohort, giving an incidence of 19.4/100 person years (95% confidence interval 18.1 to 20.8). 8770 cases presented to general practice (3.3/100 person years (2.94 to 3.75)). One case was reported to national surveillance for every 1.4 laboratory identifications, 6.2 stools sent for laboratory investigation, 23 cases presenting to general practice, and 136 community cases. The ratio of cases in the community to cases reaching national surveillance was lower for bacterial pathogens (salmonella 3.2:1, campylobacter 7.6:1) than for viruses (rotavirus 35:1, small round structured viruses 1562:1). There were many cases for which no organism was identified. Conclusions Infectious intestinal disease occurs in 1 in 5 people each year, of whom 1 in 6 presents to a general practitioner. The proportion of cases not recorded by national laboratory surveillance is large and varies widely by microorganism. Ways of supplementing the national laboratory surveillance system for infectious intestinal diseases should be considered. Key messagesInfectious intestinal disease is common, with 9.4 million estimated cases each year in EnglandIn 1.5 million cases (1 in 6) patients present to their general practitionerOnly a fraction of these cases are reported to national laboratory

This paper examines three international healthcare security systems as they relate to patient surge in Canada, Israel, and the United States. Its purpose is to compare the systems, to highlight unique characteristics that define those systems, and to initiate the development of best practices that transcend national boundaries. Several significant national characteristics of demographics, healthcare systems, and political climate, among others, present challenges to translating best practices among these three countries. However, we have found that best practice strategies exist in areas of communications, coordination, building design, space adaptability, and patient routing (both from the community to the hospital, as well as within the hospital) that can be shared and incorporated into the healthcare preparedness efforts in all three countries.

Sepsis remains one of the leading causes of death in intensive care units. Although sepsis is caused by a viral, fungal or bacterial infection, it is the dysregulated generalized host response that ultimately leads to severe dysfunction of multiple organs and death. The concomitant profound metabolic changes are characterized by hyperglycemia, insulin resistance, and profound transformations of the intracellular energy supply in both peripheral and immune cells. A further hallmark of the early phases of sepsis is a massive formation of reactive oxygen (ROS; e.g., superoxide) as well as nitrogen (RNS; e.g., nitric oxide) species. Reactive carbonyl species (RCS) form a third crucial group of highly reactive metabolites, which until today have been not the focus of interest in sepsis. However, we previously showed in a prospective observational clinical trial that patients suffering from septic shock are characterized by significant methylglyoxal (MG)-derived carbonyl stress, with the glyoxalase system being downregulated in peripheral blood mononuclear cells. In this review, we give a detailed insight into the current state of research regarding the metabolic changes that entail an increased MG-production in septicemia. Thus, we point out the special role of the glyoxalase system in the context of sepsis. PMID:28304355

Aeromonas hydrophila is a facultatively anaerobic, asporogenous gram-negative rod that has often been regarded as an opportunistic pathogen in hosts with impairment of a local or general defense mechanism. A 68-year-old alcoholic woman presented with shock and gangrene on the right arm. At first, her clinical presentations were severe painful erythematous swelling that worsened within a few hours with development of gangrene, edema, and blisters. Bullous fluid and blood cultures yielded A. hydrophila. Histopathological findings of sections obtained from the vesicle revealed subepidermal vesicles; necrosis of the epidermis, papillary dermis, and subcutaneous fat; and massive hemorrhage in the subcutis. Despite all efforts to save the patient, she died 8 hours after admission. Clinical features of A. hydrophila sepsis resemble those of Vibrio vulnificus sepsis. Therefore, in addition to the case report, we compared the cultural, biochemical, and morphological differences between A. hydrophila and V. vulnificus for facilitation of early and accurate identification of the causative agent.

The incidence of neonatal early onset sepsis has declined with the widespread use of intrapartum antibiotic therapies, yet early onset sepsis remains a potentially fatal condition, particularly among very low birth-weight infants. Clinical signs of neonatal infection are nonspecific and may be absent in the immediate postnatal period. Maternal and infant clinical characteristics, as well as infant laboratory values, have been used to identify newborns at risk and to administer empiric antibiotic therapy to prevent progression to more severe illness. Such approaches result in the evaluation of approximately 15% of asymptomatic term and late preterm infants and of nearly all preterm infants. The development of multivariate predictive models may provide more accurate methods of identifying newborns at highest risk and allow for more limited newborn antibiotic exposures.

Carbon monoxide (CO), a low-molecular-weight gas, is endogenously produced in the body as a product of heme degradation catalyzed by heme oxygenase (HO) enzymes. As the beneficial roles of HO system have been elucidated in vitro and in vivo, CO itself has also been reported as a potent cytoprotective molecule. Whereas CO represents a toxic inhalation hazard at high concentration, low-dose exogenous CO treatment (~250-500 parts per million) demonstrates protective functions including but not limited to the anti-inflammatory and antiapoptotic effects in preclinical models of human diseases. Of note, CO exposure confers protection in animal models of sepsis by inhibiting inflammatory responses and also enhancing bacterial phagocytosis in leukocytes. These unique functions of CO including both dampening inflammation and promoting host defense mechanism are mediated by multiple pathways such as autophagy induction or biosynthesis of specialized proresolving lipid mediators. We suggest that CO gas may represent a novel therapy for patients with sepsis.
Cellular immunosuppression appears to be involved in sepsis and sepsis-induced multiple organ dysfunction syndrome (MODS). Recent evidence showed that parenteral vitamin C (Vit C) had the ability to attenuate sepsis and sepsis-induced MODS. Herein, we investigated the impact of parenteral Vit C on cellular immunosuppression and the therapeutic value in sepsis. Using cecal ligation and puncture (CLP), sepsis was induced in WT and Gulo−/− mice followed with 200 mg/Kg parenteral Vit C administration. The immunologic functions of CD4+CD25+ regulatory T cells (Tregs) and CD4+CD25− T cells, as well as the organ functions, were determined. Administration of parenteral Vit C per se markedly improved the outcome of sepsis and sepsis-induced MODS of WT and Gulo−/− mice. The negative immunoregulation of Tregs was inhibited, mainly including inhibiting the expression of forkhead helix transcription factor- (Foxp-) 3, cytotoxic T lymphocyte associated antigen- (CTLA-) 4, membrane associated transforming growth factor-β (TGF-βm+), and the secretion of inhibitory cytokines [including TGF-β and interleukin- (IL-) 10], as well as CD4+ T cells-mediated cellular immunosuppression which was improved by parenteral Vit C in WT and Gulo−/− septic mice. These results suggested that parenteral Vit C has the ability to improve the outcome of sepsis and sepsis-induced MODS and is associated with improvement in cellular immunosuppression. PMID:28210072

After the discovery of the key components of the protein C (PC) pathway a beneficial effect on survival of the infusion of activated protein C (APC) in animal models of sepsis was demonstrated, leading to the development of recombinant human activated protein C (rh-APC) as a therapeutic agent. It soon became clear that rather than the anticoagulant and profibrinolytic activities of APC, its anti-inflammatory and cytoprotective properties played a major role in the treatment of patients with severe sepsis. Such properties affect the response to inflammation of endothelial cells and leukocytes and are exerted through binding of APC to at least five receptors with intracellular signaling. The main APC protective mechanism involves binding of the Gla-domain to the endothelial protein C receptor (EPCR) and cleavage of protease activated receptor 1 (PAR-1), eliciting suppression of proinflammatory cytokines synthesis and of intracellular proapoptotic pathways and activation of endothelial barrier properties. However, thrombin cleaves PAR-1 with much higher catalytic efficiency, followed by pro-inflammatory, pro-apoptotic and barrier disruptive intracellular signaling, and it is unclear how APC can exert a protective activity through the cleavage of PAR-1 when thrombin is also present in the same environment. Interestingly, in endothelial cell cultures, PAR-1 cleavage by thrombin results in anti-inflammatory and barrier protective signaling provided occupation of EPCR by the PC gla-domain, raising the possibility that the beneficial effects of rh-APC might be recapitulated in vivo by administration of h-PC zymogen to patients with severe sepsis. Recent reports of h-PC infusion in animal models of sepsis support this hypothesis.

The NAGT professional development program "On the Cutting Edge" recently surveyed 7000 geoscience faculty in the United States to develop a snapshot of current instructional practices in undergraduate geoscience courses, faculty strategies for learning new content and new teaching approaches, and faculty involvement in the geoscience education community. Over 2200 faculty responded to the survey which was conducted by the American Institute of Physics. Results for introductory courses (814 responses) indicate that lecture is the most common teaching strategy used in courses of all sizes. Many faculty incorporate some interactive activities in their courses. Most commonly, they use questioning, demonstrations, discussions, and in-class exercises. Less common, but not rare, are small group discussion or think-pair-share and classroom debates or role-playing. Activities involving problem solving, using quantitative skills, working with data and primarily literature, and structured collaboration are incorporated by many faculty in introductory courses, suggesting efforts to teach the process of science. Activities in which students address a problem of national or local interest, analyze their own data, or address problems of their own design are less common but not rare. Field experiences are common but not ubiquitous for students in introductory courses. A wide variety of assessment strategies are used in introductory courses of all sizes, including exams, quizzes, problem sets, papers, oral presentations, and portfolios. While papers are used for assessment more extensively in small classes, a significant number of faculty use papers in large classes (greater than 81 students). A majority of faculty use rubrics in grading. Faculty report that in the past two years, approximately one-third have made changes in the content of their introductory courses while just under half have changed the teaching methods they use. While faculty learn about both new content and

Published records of the frequency of wound sepsis are often unreliable sources of information on the general frequency of this complication because of unstandardized methods of reporting and because of the various views of different investigators as to what constitutes sepsis. A method of infection reporting, its study and analysis are outlined. A survey of postoperative infections by this method for the years 1959, 1960 and 1961 revealed infection rates of 2.02%, 1.20% and 1.14%, respectively. For the same period the percentages of wound infections caused by Staph. aureus were 83.06%, 69.8% and 51.8%, respectively. The most prevalent phage types were 55/53/54 and 52/80/81/82, although types 80/81/82 and 80 were also involved. Infections with Gram-negative organisms were encountered more often in 1961 than in 1959. The majority of these were of mixed type, and followed abdominal surgery. There is need for more comprehensive study and analysis of postoperative wound sepsis and its complications. It was apparent from this study that, statistically, a relatively low rate of postoperative infections may mask a high rate following a specific surgical procedure. PMID:13954844

In the majority of patients with severe sepsis, systemic activation of coagulation is present. Increasing evidence points to an extensive cross-talk between coagulation and inflammation that may play an important role in the pathogenesis of sepsis. Inflammation not only leads to activation of coagulation, but coagulation also considerably affects inflammatory activity. Molecular pathways that contribute to inflammation-induced activation of coagulation have been precisely identified. Proinflammatory cytokines and other mediators are capable of activating the coagulation system and downregulating important physiological anticoagulant pathways. Activation of the coagulation system and ensuing thrombin generation is dependent on expression of tissue factor on activated mononuclear cells and endothelial cells, and is insufficiently counteracted by TFPI. Simultaneously, endothelial-bound anticoagulant mechanism, in particular the protein C system, is shutoff by proinflammatory cytokines. In addition, fibrin removal is severely inhibited, because of inactivation of the fibrinolytic system, caused by an upregulation of its main inhibitor, plasminogen activator inhibitor type 1 (PAI-1). Increased fibrin formation and impaired removal lead to (micro)vascular thrombosis, which may result in tissue ischemia and subsequent organ damage. The cornerstone of the management of coagulation in sepsis is the specific and vigorous treatment of the underlying disorder. Strategies aimed at the inhibition of coagulation activation may theoretically be justified and have been found beneficial in experimental and initial clinical studies. Heparin may be an effective anticoagulant approach and alternative strategies comprise restoration of physiological anticoagulant pathways.

Ethyl pyruvate (EP), a simple aliphatic ester derived from pyruvic acid, improves survival and ameliorates organ system dysfunction in mice with peritonitis induced by caecal ligation and perforation, even when treatment is started as late as 12-24 hours after the onset of sepsis. In studies using lipopolysaccharide-stimulated RAW 264.7 murine macrophage like cells, EP inhibits activation of the pro-inflammatory transcription factor, NF-kappaB, and down regulates secretion of a number of pro-inflammatory cytokines, such as tumour necrosis factor (TNF). In this reductionist in vitro system, EP also blocks secretion of the late-appearing pro inflammatory cytokine-like molecule, high mobility group box 1 (HMGB1). In murine models of endotoxaemia or sepsis, treatment with EP decreases circulating levels of TNF and HMGB1. While the molecular events responsible for the salutary effects of EP remain to be elucidated, one mechanism may involve covalent modification of a critical thiol residue in the p65 component of NF-kappaB. EP warrants evaluation as a therapeutic agent for the treatment of sepsis in humans.

Sepsis is a systemic inflammatory response induced by an infection, leading to organ dysfunction and mortality. Historically, sepsis-induced organ dysfunction and lethality were attributed to the interplay between inflammatory and antiinflammatory responses. With advances in intensive care management and goal-directed interventions, early sepsis mortality has diminished, only to surge later after “recovery” from acute events, prompting a search for sepsis-induced alterations in immune function. Sepsis is well known to alter innate and adaptive immune responses for sustained periods after clinical “recovery,” with immunosuppression being a prominent example of such alterations. Recent studies have centered on immune-modulatory therapy. These efforts are focused on defining and reversing the persistent immune cell dysfunction that is associated with mortality long after the acute events of sepsis have resolved. PMID:26727230

Background Although the mortality rate among patients with sepsis is declining, the incidence of both sepsis and sepsis-related deaths is increasing, likely due to its presence in a growing elderly population. As atrial fibrillation is more common in the elderly, we hypothesize that its presence will be associated with greater mortality among patients with sepsis. Methods The Medical Intensive Care Unit (MICU) database of a large tertiary care medical center was queried for sepsis-related codes and atrial fibrillation. Results Atrial fibrillation was associated with older age and a higher mortality in this series of patients with sepsis. Conclusions Whether atrial fibrillation is a marker of disease severity or contributes to mortality is uncertain. Further studies are necessary to determine optimal management.

Although the prevailing concept has been that mortality in sepsis results from an unbridled hyper-inflammatory cytokine-mediated response, the failure of more than 30 clinical trials to treat sepsis by controlling this cytokine response requires a 'rethink' of the molecular mechanism underpinning the development of sepsis. As we discuss here, remarkable new studies indicate that most deaths from sepsis are actually the result of a substantially impaired immune response that is due to extensive death of immune effector cells. Rectification of this apoptotic-inflammatory imbalance using modulators of caspases and other components of the cell-death pathway have shown striking efficacy in stringent animal models of sepsis, indicating an entirely novel path forward for the clinical treatment of human sepsis.

Background: Around 1 in 10 of all cancer cases occur in adults of reproductive age. Cancer and its treatments can cause long-term effects, such as loss of fertility, which can lead to poor emotional adjustment. Unmet information needs are associated with higher levels of anxiety. US research suggests that many oncologists do not discuss fertility. Very little research exists about fertility information provision in the United Kingdom. This study aimed to explore current knowledge, practice and attitudes among oncologists in the United Kingdom regarding fertility preservation in patients of child-bearing age. Methods: A national online survey of 100 oncologists conducted online via medeconnect, a company which has exclusive access to the doctors.net.uk membership of GMC registered doctors. Results: Oncologists saw fertility preservation (FP) as mainly a women's issue, and yet only felt knowledgeable about sperm storage, not other methods of FP; 87% expressed a need for more information. Most reported discussing the impact of treatment on fertility with patients, but only 38% reported routinely providing patients with written information, and 1/3 reported they did not usually refer patients who had questions about fertility to a specialist fertility service. Twenty-three per cent had never consulted any FP guidelines. The main barriers to initiating discussions about FP were lack of time, lack of knowledge, perceived poor success rates of FP options, poor patient prognosis and, to a lesser extent, if the patient already had children, was single, or could not afford FP treatment. Conclusion: The findings from this study suggest a deficiency in UK oncologist's knowledge about FP options and highlights that the provision of information to patients about FP may be sub-optimal. Oncologists may benefit from further education, and further research is required to establish if patients perceive a need for further information about FP options. PMID:23579214

Despite its popularity elsewhere, C has not been extensively used for scientific programming on supercomputers. There are a number of reasons for this but perhaps the most compelling has been the lack of C compilers. However, this situation has recently begun to change at the National Magnetic Fusion Energy Computing Center (NMFECC) where two C development platforms --- the Hybrid C Compiler (HCC) written at the Livermore Computer Center and the Portable C Compiler (CC version 4.1) distributed by Cray Research, Inc. (CRI) --- have become available for use. These compilers produce object code for all of the Cray models at NMFECC and, in addition, possess good scalar optimization capabilities along with rudimentary vectorization capabilities. With the advent of the Cray C compilers, it is possible to consider physics code development in C at NMFECC. However, when one actually attempts to pursue this goal, one is quickly faced with a number of practical problems. For instance, How do I compile, link, and debug C codes What special features of C are useful to me as a scientific programmer Are there things I currently can't do in C programs How do I interface my C program to existing Fortran code Can I make use of the Basis code development system from C Over the last three years we have incorporated C into numerous physics codes written at NMFECC and, in the course of this work, we have had to develop solutions to all of the above problems. This turned out to be a surprisingly frustrating and time-consuming venture requiring some rather subtle techniques and hacks. This guide is an attempt to document these techniques.

Sepsis remains a major cause of morbidity and mortality in adult and pediatric intensive care units. Heterogeneity of demographics, comorbidities, biological mechanisms, and severity of illness leads to difficulty in determining which patients are at highest risk of mortality. Determining mortality risk is important for weighing the potential benefits of more aggressive interventions and for deciding whom to enroll in clinical trials. Biomarkers can be used to parse patients into different risk categories and can outperform current methods of patient risk stratification based on physiologic parameters. Here we review the Pediatric Sepsis Biomarker Risk Model that has also been modified and applied to estimate mortality risk in adult patients. We compare the two models and speculate on the biological implications of the biomarkers in patients with sepsis. PMID:24754535

Objective Thiamin deficiency is highly prevalent in patients with sepsis, but the mechanism by which sepsis induces thiamin deficiency is unknown. This study aimed to determine the influence of various severity of sepsis on carrier-mediated intestinal thiamin uptake, level of expressions of thiamin transporters (thiamin transporter-1 (THTR-1) and thiamin transporter-2 (THTR-2)), and mitochondrial thiamin pyrophosphate transporter (MTPPT). Design Randomized, controlled study Setting Research laboratory at a Veterans Affairs Medical Center Subjects Twenty-four Sprague-Dawley rats were randomized into controls, mild, moderate and severe sepsis with equal number of animals in each group. Measurements and Main Results Sepsis was induced by cecal ligation and puncture with the cecum ligated below the cecal valve at 25 %, 50 % and 75 % of cecal length, defined as severe, moderate and mild sepsis, respectively. Control animals underwent laparotomy only. After 2 days of induced sepsis, carrier-mediated intestinal thiamin uptake was measured using [3H]thiamin. Expressions of THTR-1, THTR-2, and MTPPT proteins and mRNA were measured. Proinflammatory cytokines (IL-1β and IL-6), and adenosine triphosphate (ATP) were also measured. Sepsis inhibited [3H]thiamin uptake and the inhibition was a function of sepsis severity. Both cell membranes thiamin transporters and MTPPT expression levels were suppressed; also levels of ATP in the intestine of animals with moderate and severe sepsis were significantly lower than that of sham operated controls. Conclusions For the first time we demonstrated that sepsis inhibited carrier-mediated intestinal thiamin uptake as a function of sepsis severity, suppressed thiamin transporters and MTPPT, leading to ATP depletion.

Objectives Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, and sepsis is a frequent cause of death in hospitalised patients. We investigated the relationship between ALS and the subsequent risk of sepsis. Design A retrospective cohort analysis. Setting Patients with ALSs diagnosed between 2000 and 2010 in Taiwan National Health Insurance Research Database. Participants We included 701 and 2804 patients as the ALS and the non-ALS groups, respectively. Outcome measures The risk of sepsis was calculated by Cox proportional hazards regression model. Results During the follow-up period, the incidence density rates were 77.8 and 11.1 per 1000 person-years in the ALS and non-ALS groups, respectively. After adjusting for sex, age, Charlson comorbidity index score, life-support measures, and β2-adrenoceptor agonists treatment, the ALS group had a higher risk of sepsis (HR=3.42; 95% CI 2.60 to 4.50) than the non-ALS group. An increase of the risk was observed in patients with ALS receiving life support treatment measures, whereas a decrease of the risk was associated with treatment of β2-adrenoceptor agonists. Conclusions The risk of sepsis is associated with a prior ALS diagnosis, and may be increased by the use of life support measures and decreased by β2-adrenoceptor agonists. PMID:28093437

Several biochemical markers have been proposed over the past years to manage critically ill newborns with acute inflammation and sepsis. The state of the art in diagnosing and monitoring neonatal sepsis, severe sepsis and septic shock consists of the measurement of plasma C-reactive protein (CRP) and procalcitonin (PCT) at the onset and in the course of the disease. CRP and PCT in combination are clinically significant in diagnosing and monitoring septic newborns; however, CRP and PCT have a very limited value for risk stratification and in predicting outcome. The availability of commercial methods for the automated measurement of the soluble CD14 subtype presepsin (sCD14-ST) and lipopolysaccharide binding protein (LBP) represent a challenge for the evaluation in clinical practice of reliable markers of neonatal sepsis, specifically for the very early diagnosis, the classification into class of severity, and the prediction of complications and death.

Sepsis is a systemic inflammatory response to infection. Sepsis, which can lead to severe sepsis, septic shock, and multiple organ dysfunction syndrome, is an important cause of mortality. Pathogenesis is extremely complex. In recent years, cell hypoxia caused by mitochondrial dysfunction has become a hot research field. Sepsis damages the structure and function of mitochondria, conversely, mitochondrial dysfunction aggravated sepsis. The treatment of sepsis lacks effective specific drugs. The aim of this paper is to undertake a narrative review of the current experimental treatment for mitochondrial dysfunction in sepsis. The search was conducted in PubMed databases and Web of Science databases from 1950 to January 2014. A total of 1,090 references were retrieved by the search, of which 121 researches met all the inclusion criteria were included. Articles on the relationship between sepsis and mitochondria, and drugs used for mitochondrial dysfunction in sepsis were reviewed retrospectively. The drugs were divided into four categories: (1) Drug related to mitochondrial matrix and respiratory chain, (2) drugs of mitochondrial antioxidant and free radical scavengers, (3) drugs related to mitochondrial membrane stability, (4) hormone therapy for septic mitochondria. In animal experiments, many drugs show good results. However, clinical research lacks. In future studies, the urgent need is to develop promising drugs in clinical trials. PMID:25983774

Sensory neurons play important roles in many disorders, including inflammatory diseases, such as sepsis. Sepsis is a potentially lethal systemic inflammatory reaction to a local bacterial infection, affecting thousands of patients annually. Although associated with a high mortality rate, sepsis outcome depends on the severity of systemic inflammation, which can be directly influenced by several factors, including the immune response of the patient. Currently, there is a lack of effective drugs to treat sepsis, and thus there is a need to develop new drugs to improve sepsis outcome. Several mediators involved in the formation of sepsis have now been identified, but the mechanisms underlying the pathology remain poorly understood. The transient receptor potential vanilloid 1 (TRPV1) receptor and the neuropeptide substance P (SP) have recently been demonstrated as important targets for sepsis and are located on sensory neurones and non-neuronal cells. Herein, we highlight and review the importance of sensory neurones for the modulation of sepsis, with specific focus on recent findings relating to TRPV1 and SP, with their distinct abilities to alter the transition from local to systemic inflammation and also modify the overall sepsis outcome. We also emphasize the protective role of TRPV1 in this context. LINKED ARTICLES This article is part of a themed section on Neuropeptides.

Sepsis is a serious medical condition that occurs in 30% of patients in intensive care units (ICUs). Early detection of sepsis is key to prevent its progression to severe sepsis and septic shock, which can cause organ failure and death. Diagnostic criteria for sepsis are nonspecific and hinder a timely diagnosis in patients. Therefore, there is currently a large effort to detect biomarkers that can aid physicians in the diagnosis and prognosis of sepsis. Mass spectrometry is often the method of choice to detect metabolomic and proteomic changes that occur during sepsis progression. These "omics" strategies allow for untargeted profiling of thousands of metabolites and proteins from human biological samples obtained from septic patients. Differential expression of or modifications to these metabolites and proteins can provide a more reliable source of diagnostic biomarkers for sepsis. Here, we focus on the current knowledge of biomarkers of sepsis and discuss the various mass spectrometric technologies used in their detection. We consider studies of the metabolome and proteome and summarize information regarding potential biomarkers in both general and neonatal sepsis.

Due to the introduction of the conjugate vaccine against serotype b, neonatal sepsis caused by Haemophilus influenzae became very rare. There is little data in Belgium concerning the prevalence of H. influenzae early onset neonatal sepsis and articles about neonatal sepsis and H. influenzae published in the last decade are scarce. We report two invasive infections with a non-typeable H. influenzae. These cases show that neonatal sepsis caused by non-typeable H. influenzae may be underestimated and we believe that there is need for a better registration of this kind of infection.
Sepsis is a life threatening condition mediated by systemic infection, but also triggered by hemorrhage and trauma. These are significant causes of organ injury implicated in morbidity and mortality, as well as post-sepsis complications associated with dysfunction of innate and adaptive immunity. The role of cellular bioenergetics and loss of metabolic plasticity of immune cells is increasingly emerging in the pathogenesis of sepsis. This review describes mitochondrial biology and metabolic alterations of immune cells due to sepsis, as well as indicates plausible therapeutic opportunities. PMID:28378540

Sepsis and septic shock are among mortality causes following major surgeries. The Charlson co-morbidity index consists of 19 weighted categories related to chronic health which measures the burden of co-morbidity. The goal of this study was to determine the incidence of postoperative sepsis in patients underwent gynecological and gastrointestinal cancer surgeries and predictive role of Charlson index for this situation. Two hundred and twenty-two patients who underwent gynecological and gastrointestinal cancer surgeries were evaluated. Sixty-four (28.6%) patients developed SIRS postoperatively. Forty-four (19.7%) patients developed sepsis postoperatively. Mean age, duration of hospitalization and surgery, the Charlson score were significantly higher in patients who developed sepsis than other cases. Blood transfusion and Charlson score were independent predictors of sepsis occurrence. Charlson co-morbidity index is a predictive factor for developing postoperative sepsis.

Background The South African government intends to contract with ‘accredited provider groups’ for capitated primary care under National Health Insurance (NHI). South African solo general practitioners (GPs) are unhappy with group practice. There is no clarity on the views of GPs in group practice on contracting to the NHI. Objectives To describe the demographic and practice profile of GPs in group practice in South Africa, and evaluate their views on NHI, compared to solo GPs. Methods This was a descriptive survey. The population of 8721 private GPs in South Africa with emails available were emailed an online questionnaire. Descriptive statistical analyses and thematic content analysis were conducted. Results In all, 819 GPs responded (568 solo GPs and 251 GPs in groups). The results are focused on group GPs. GPs in groups have a different demographic practice profile compared to solo GPs. GPs in groups expected R4.86 million ($0.41 million) for a hypothetical NHI proposal of comprehensive primary healthcare (excluding medicines and investigations) to a practice population of 10 000 people. GPs planned a clinical team of 8 to 12 (including nurses) and 4 to 6 administrative staff. GPs in group practices saw three major risks: patient, organisational and government, with three related risk management strategies. Conclusions GPs can competitively contract with NHI, although there are concerns. NHI contracting should not be limited to groups. All GPs embraced strong teamwork, including using nurses more effectively. This aligns well with the emergence of family medicine in Africa. PMID:27380785

Given the high unmet need for palliative care in Africa and other resource limited settings, it is important that countries embrace the public health approach to increasing access through its integration within existing healthcare systems. To give this approach a strong foundation that would ensure sustainability, the World Health Organisation urges member states to ensure that policy environments are suitable for this intervention. The development, strengthening, and implementation of national palliative care policies is a priority. Given the lack of a critical mass of palliative care professionals in the region and deficiency in documenting and sharing best practices as part of information critical for regional development, policy development becomes a complex process. This article shares experiences with regard to best practices when advocating the national palliative care policies. It also tells about policy development process, the important considerations, and cites examples of policy content outlines in Africa.

New treatments against malaria (artemisinin-based combination therapies, ACT) resulted in profound changes in the therapeutic behaviours in Africa. This study aims to evaluate the practices adaptation to the new strategies in Benin in 2009. In three southern areas of the country, 14 private pharmacies, 10 public health centers and 10 private health centers were audited. Between July and October 2009, 36 providers and 93 prescribers were interviewed, 127 dispensations for self-medication were observed, 210 prescriptions were analyzed according to the WHO recommendations, 251 patients with complaints of malaria and 50 healthy women were interviewed and 34 physical inventories were conducted in pharmacies. Knowledge and trainings were inadequate, especially in the private sector and for the providers, as 41.6% of requests for antimalarial drugs were without prescription in private pharmacies. Only 28% of prescribers and 47% of providers knew the national recommendations of 1st line treatment for uncomplicated malaria. 53% of prescribers treated patients by ACT without prior parasitological examination in the case of uncomplicated malaria and no Rapid Diagnostic Test (RDT) was carried out or requested during the dispensation. Pharmaceutical advices were absent in 78.7% of cases and population acknowledged a lack of knowledge about use of the treatment. Private pharmacies were structures where the variability of available antimalarial drugs was the largest, up to 70 different specialities and where unit prices were highest, up to 7.7 times those charged in public health centers. In the field, the difficulties of application of recommendations, given at the scientific or political level, show the necessity of accompanying policy change by prior training activities of all health stakeholders and of adapting the previous regulations to facilitate implementation of the new rules. The number of authorizations issued for the ACT should be limited; authorization to chloroquine

There has been considerable debate and little empirical data on the role of psychotherapy treatment manuals in clinical practice. Attitudes toward treatment manuals are a potentially important determinant of how likely practitioners are to use manual-based treatments in clinical practice. A total of 891 practicing psychologists nationwide were surveyed about their attitudes toward treatment manuals and their ideas about the content of manuals. Practitioners held widely varying attitudes toward treatment manuals, and ideas about what constitutes a manual were associated with attitudes in a predictable way. Recommendations are made for how to gather more useful information about practitioners' attitudes toward the many changes affecting current models of clinical practice.

Objectives: Vitamin D deficiency has been implicated as a pathogenic factor in sepsis and ICU mortality but causality of these associations has not been demonstrated. To determine whether sepsis and severe sepsis are associated with vitamin D deficiency and to determine whether vitamin D deficiency influences the severity of sepsis. Design, Setting, and Patients: Sixty-one patients with sepsis and severe sepsis from two large U.K. hospitals and 20 healthy controls were recruited. Murine models of cecal ligation and puncture and intratracheal lipopolysaccharide were undertaken in normal and vitamin D deficient mice to address the issue of causality. Measurements and Main Results: Patients with severe sepsis had significantly lower concentrations of 25-hydroxyvitamin D3 than patients with either mild sepsis or age-matched healthy controls (15.7 vs 49.5 vs 66.5 nmol/L; p = 0.0001). 25-hydroxyvitamin D3 concentrations were significantly lower in patients who had positive microbiologic culture than those who were culture negative (p = 0.0023) as well as those who died within 30 days of hospital admission (p = 0.025). Vitamin D deficiency in murine sepsis was associated with increased peritoneal (p = 0.037), systemic (p = 0.019), and bronchoalveolar lavage (p = 0.011) quantitative bacterial culture. This was associated with reduced local expression of the cathelicidin-related antimicrobial peptide as well as evidence of defective macrophage phagocytosis (p = 0.029). In the intratracheal lipopolysaccharide model, 1,500 IU of intraperitoneal cholecalciferol treatment 6 hours postinjury reduced alveolar inflammation, cellular damage, and hypoxia. Conclusions: Vitamin D deficiency is common in severe sepsis. This appears to contribute to the development of the condition in clinically relevant murine models and approaches to correct vitamin D deficiency in patients with sepsis should be developed.

In Tanzania, there is paucity of data for monitoring laboratory medicine including haematology. This therefore calls for audits of practices in haematology and blood transfusion in order to provide appraise practice and devise strategies that would result in improved quality of health care services. This descriptive cross-sectional study which audited laboratory practice in haematology and blood transfusion at Muhimbili National Hospital (MNH) aimed at assessing the pre-analytical stage of laboratory investigations including laboratory request forms and handling specimen processing in the haematology laboratory and assessing the chain from donor selection, blood component processing to administration of blood during transfusion. A national standard checklist was used to audit the laboratory request forms (LRF), phlebotomists' practices on handling and assessing the from donor selection to administration 6f blood during transfusion. Both interview and observations were used. A total of 195 LRF were audited and 100% of had incomplete information such as patients' identification numbers, time sample ordered, reason for request, summary of clinical assessment and differential diagnoses. The labelling of specimens was poorly done by phlebotomists/clinicians in 82% of the specimens. Also 65% (132/202) of the blood samples delivered in the haematology laboratory did not contain the recommended volume of blood. There was no laboratory request form specific for ordering blood and there were no guidelines for indication of blood transfusion in the wards/ clinics. The blood transfusion laboratory section was not participating in external quality assessment and the hospital transfusion committee was not in operation. It is recommended that a referral hospital like MNH should have a transfusion committee to provide an active forum to facilitate communication between those involved with transfusion, monitor, coordinate and audit blood transfusion practices as per national

Regarding genetic biomarkers for early assessment and monitoring the clinical course in polytrauma patients with sepsis, in recent years a remarkable evolution has been highlighted. One of the main representatives is the exosome miRNAs. In this paper, we would like to present in more details the various methods of using exosome miRNAs as a biomarker for monitoring polytrauma patients with sepsis, as well as establishing a belated outcome by aggregating the entire clinical aspects. The use of exosome miRNAs for late evaluating and monitoring the clinical evolution of polytrauma patients can bring significant improvements in current clinical practice through the optimization and modulation of intensive care according to the needs of each patient individually.

Australia is the sixth biggest (by area) country in the world, having a total area of about 7.5 million km(2) (3 million square miles). This study located every dental practice in the country (private and public) and mapped these practices against population. The total population of Australia (21.5 million) is distributed across 8,529 suburbs. On average about one-third of the population from each State lives in suburbs without practices and 46% live in suburbs with one to five dentists. Of those living within the study frameset, 86.6% live within 5 km of a private practice and 84.4% live within 10 km of a government practice. Australia's dental practices are distributed in a very uneven fashion across its vast area. Three-quarters of suburbs have no dental practice and over one-third of the population live in these suburbs. This research clearly identified that in a vast and uneven socio-geographically distributed country, service planning, if left to market forces, will end with a practice distribution that is fixed by economic drivers of scale and not that of disease burden. A more population health-driven approach to future design and construction of government safety net services is needed to address these disparities.

Introduction A preliminary study done by a National Dental Practice-Based Research Network precursor observed that 44% of general dentists (GDs) reported always using a rubber dam (RD) during root canal treatment (RCT). This full-scale study quantified use of all isolation techniques, including RD use. Methods Network practitioners completed a questionnaire about isolation techniques used during RCT. Network Enrollment Questionnaire data provided practitioner characteristics. Results 1,490 of 1,716 eligible GDs participated (87%); 697 (47%) reported always using a RD. This percentage varied by tooth type. These GDs were more likely to always use a RD: do not own a private practice; perform less than 10 RCT/month; have postgraduate training. Conclusions Most GDs do not use a RD all the time. Ironically, RDs are used more frequently by GDs who do not perform molar RCT. RD use varies with tooth type and certain dentist, practice, and patient characteristics. PMID:26015159
Background Outcomes in patients with sepsis are better if initial empirical antimicrobial use is appropriate. Several studies have shown that adherence to guidelines dictating appropriate antimicrobial use positively influences clinical outcome, shortens length of hospital stay and contributes to the containment of antibiotic resistance. Quality indicators (QIs) can be systematically developed from these guidelines to define and measure appropriate antimicrobial use. We describe the development of a concise set of QIs to assess the appropriateness of antimicrobial use in adult patients with sepsis on a general medical ward or Intensive Care Unit (ICU). Methods A RAND-modified, five step Delphi procedure was used. A multidisciplinary panel of 14 experts appraised and prioritized 40 key recommendations from within the Dutch national guideline on antimicrobial use for adult hospitalized patients with sepsis (http://www.swab.nl/guidelines). A procedure to select QIs relevant to clinical outcome, antimicrobial resistance and costs was performed using two rounds of questionnaires with a face-to-face consensus meeting between the rounds over a period of three months. Results The procedure resulted in the selection of a final set of five QIs, namely: obtain cultures; prescribe empirical antimicrobial therapy according to the national guideline; start intravenous drug therapy; start antimicrobial treatment within one hour; and streamline antimicrobial therapy. Conclusion This systematic, stepwise method, which combined evidence and expert opinion, led to a concise and therefore feasible set of QIs for optimal antimicrobial use in hospitalized adult patients with sepsis. The next step will entail subjecting these quality indicators to an applicability test for their clinimetric properties and ultimately, using these QIs in quality-improvement projects. This information is crucial for antimicrobial stewardship teams to help set priorities and to focus improvement. PMID

Introduction. Deescalation refers to either discontinuation or a step-down of antimicrobials. Despite strong recommendations in the Surviving Sepsis Guidelines (2012) to deescalate, actual practices can vary. Our objective was to identify variables that are associated with deescalation failure. Methods. In this prospective study of patients with sepsis/septic shock, patients were categorized into 4 groups based on antibiotic administration: no change in antibiotics, deescalation, escalation (where antibiotics were changed to those with a broader spectrum of antimicrobial coverage), or mixed changes (where both escalation to a broader spectrum of coverage and discontinuation of antibiotics were carried out). Results. 395 patients were studied; mean APACHE II score was 24 ± 7.8. Antimicrobial deescalation occurred in 189 (48%) patients; no changes were made in 156 (39%) patients. On multivariate regression analysis, failure to deescalate was significantly predicted by hematologic malignancy OR 3.3 (95% CI 1.4–7.4) p < 0.004, fungal sepsis OR 2.7 (95% CI 1.2–5.8) p = 0.011, multidrug resistance OR 2.9 (95% CI 1.4–6.0) p = 0.003, baseline serum procalcitonin OR 1.01 (95% CI 1.003–1.016) p = 0.002, and SAPS II scores OR 1.01 (95% CI 1.004–1.02) p = 0.006. Conclusions. Current deescalation practices reflect physician reluctance when dealing with complicated, sicker patients or with drug-resistance or fungal sepsis. Integrating an antibiotic stewardship program may increase physician confidence and provide support towards increasing deescalation rates. PMID:27493799
Sepsis is responsible for the utilisation of a significant proportion of healthcare resources and has high mortality rates. Early diagnosis and prompt interventions are associated with better outcomes but is impeded by a lack of diagnostic tools and the heterogeneous and enigmatic nature of sepsis. The recently updated definitions of sepsis have moved away from the centrality of inflammation and the systemic inflammatory response syndrome (SIRS) criteria which have been shown to be non-specific. Sepsis is now defined as a “life-threatening organ dysfunction caused by a dysregulated host response to infection”. The Quick (q) Sequential (Sepsis-related) Organ Failure Assessment (SOFA) score is proposed as a surrogate for organ dysfunction and may act as a risk predictor for patients with known or suspected infection, as well as being a prompt for clinicians to consider the diagnosis of sepsis. Early warning scores (EWS) are track and trigger physiological monitoring systems that have become integrated within many healthcare systems for the detection of acutely deteriorating patients. The recent study by Churpek and colleagues sought to compare qSOFA to more established alerting criteria in a population of patients with presumed infection, and compared the ability to predict death or unplanned intensive care unit (ICU) admission. This perspective paper discusses recent advances in the diagnostic criteria for sepsis and how qSOFA may fit into the pre-existing models of acute care and sepsis quality improvement. PMID:28149888
Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The endothelial glycocalyx is one of the earliest sites involved during sepsis. This fragile layer is a complex network of cell-bound proteoglycans, glycosaminoglycan side chains, and sialoproteins lining the luminal side of endothelial cells with a thickness of about 1 to 3 μm. Sepsis-associated alterations of its structure affect endothelial permeability and result in the liberation of endogenous damage-associated molecular patterns (DAMPs). Once liberated in the circulatory system, DAMPs trigger the devastating consequences of the proinflammatory cascades in sepsis and septic shock. In this way, the injury to the glycocalyx with the consecutive release of DAMPs contributes to a number of specific clinical effects of sepsis, including acute kidney injury, respiratory failure, and septic cardiomyopathy. Moreover, the extent of glycocalyx degradation serves as a marker of endothelial dysfunction and sepsis severity. In this review, we highlight the crucial role of the glycocalyx in sepsis as a diagnostic tool and discuss the potential of members of the endothelial glycocalyx serving as hopeful therapeutic targets in sepsis-associated multiple organ failures.

Microbes activate pattern recognition receptors to initiate adaptive immunity. T cells affect early innate inflammatory responses to viral infection, but both activation and suppression have been demonstrated. We identify a novel role for B cells in the early innate immune response during bacterial sepsis. We demonstrate that Rag1−/− mice display deficient early inflammatory responses and reduced survival during sepsis. Interestingly, B cell–deficient or anti-CD20 B cell–depleted mice, but not α/β T cell–deficient mice, display decreased inflammatory cytokine and chemokine production and reduced survival after sepsis. Both treatment of B cell–deficient mice with serum from wild-type (WT) mice and repletion of Rag1−/− mice with B cells improves sepsis survival, suggesting antibody-independent and antibody-dependent roles for B cells in the outcome to sepsis. During sepsis, marginal zone and follicular B cells are activated through type I interferon (IFN-I) receptor (IFN-α/β receptor [IFNAR]), and repleting Rag1−/− mice with WT, but not IFNAR−/−, B cells improves IFN-I–dependent and –independent early cytokine responses. Repleting B cell–deficient mice with the IFN-I–dependent chemokine, CXCL10 was also sufficient to improve sepsis survival. This study identifies a novel role for IFN-I–activated B cells in protective early innate immune responses during bacterial sepsis. PMID:21746813

Systemic immune dysregulation is generally acknowledged to be the fundamental molecular mechanism that underlies the pathophysiology of severe sepsis and septic shock. In the presence of a systemic infection, microbial pathogens and their soluble mediators induce generalised immune activation and coagulation activation, leading to severe sepsis and septic shock. For decades, immune-based therapies have been devised with the specific intent of inhibiting the pro-inflammatory events that are thought to precipitate the septic process. Despite a clear therapeutic rationale based upon the available experimental evidence, anti-inflammatory therapies targeting the innate or acquired immune response have largely been unsuccessful in clinical trials of sepsis. Compelling evidence now exists that a prolonged state of sepsis-induced immune suppression follows the initial period of stabilisation and resuscitation in many critically ill patients. Sepsis-related immune suppression is evidenced by histological findings of markedly enhanced lymphocytic and monocytic apoptosis, poor response to neoantigens and recall antigens, and increased incidence of infections by opportunistic pathogens. Candidiasis, cytomegalovirus activation and secondary infections by relatively avirulent bacterial pathogens such as Stenotrophomonas and Acinetobacter spp. are commonplace in septic patients during prolonged Intensive Care Unit stays. Immunological tools to detect sepsis-induced immunosuppression are now available, and novel immunoadjuvants are in development to re-establish immune competence in sepsis patients. The intelligent use of immunomodulatory agents in sepsis will necessitate a personalised medicine approach to treat each patient at the appropriate time and with the optimal therapy.

Fluid resuscitation continues to be recommended as the first-line resuscitative therapy for all patients with severe sepsis and septic shock. The current acceptance of the therapy is based in part on long history and familiarity with its use in the resuscitation of other forms of shock, as well as on an incomplete and incorrect understanding of the pathophysiology of sepsis. Recently, the safety of intravenous fluids in patients with sepsis has been called into question with both prospective and observational data suggesting improved outcomes with less fluid or no fluid. The current evidence for the continued use of fluid resuscitation for sepsis remains contentious with no prospective evidence demonstrating benefit to fluid resuscitation as a therapy in isolation. This article reviews the historical and physiological rationale for the introduction of fluid resuscitation as treatment for sepsis and highlights a number of significant concerns based on current experimental and clinical evidence. The research agenda should focus on the development of hyperdynamic animal sepsis models which more closely mimic human sepsis and on experimental and clinical studies designed to evaluate minimal or no fluid strategies in the resuscitation phase of sepsis.

Prolonged preoperative fasting can be associated with adverse outcomes, particularly in children. Our aims were to assess the time pediatric patients fasted prior to surgical or radiologic procedures and evaluate whether fasting (NPO) orders complied with national guidelines. We measured NPO start time, time of last intake, and time test or surgery was scheduled, took place, or was cancelled in 219 pediatric patients. Findings demonstrate that pediatric patients experienced prolonged fasting before procedures and that the majority of NPO orders were non-compliant with national guidelines. We have developed strategies to reduce fasting times and ensure compliance with recommended national fasting standards.

Objective Immune dysfunction, including prominent apoptosis of immune cells and decreased functioning of the remaining immune cells, plays a central role in the pathogenesis of sepsis. Sterile α and HEAT/armadillo motif-containing protein (SARM) is implicated in the regulation of immune cell apoptosis. This study aimed to elucidate SARM contributes to sepsis-induced immune cell death and immunosuppression. Methods A mouse model of polymicrobial sepsis was generated by cecum ligation and puncture (CLP). SARM gene and protein expression, caspase 3 cleavage and intracellular ATP production were measured in the mouse spleens. Results CLP-induced polymicrobial sepsis specifically attenuated both the gene and protein expression of SARM in the spleens. Moreover, the attenuation of SARM expression synchronized with splenocyte apoptosis, as evidenced by increased caspase 3 cleavage and ATP depletion. Conclusions These findings suggest that SARM is a potential regulator of sepsis-induced splenocyte apoptosis.

On one side, brain dysfunction is a poorly explored complication of sepsis. On the other side, brain dysfunction may actively contribute to the pathogenesis of sepsis. The current review aimed at summarizing the current knowledge about the reciprocal interaction between the immune and central nervous systems during sepsis. The immune-brain cross talk takes part in circumventricular organs that, being free from blood-brain-barrier, interface between brain and bloodstream, in autonomic nuclei including the vagus nerve, and finally through the damaged endothelium. Recent observations have confirmed that sepsis is associated with excessive brain inflammation and neuronal apoptosis which clinical relevance remains to be explored. In parallel, damage within autonomic nervous and neuroendocrine systems may contribute to sepsis induced organ dysfunction. PMID:15693982

Sepsis is one of the leading causes of death in critically ill patients in the intensive care unit. Sepsis accounts for significant morbidity and mortality in critically ill children as well. The pathophysiology of sepsis is characterized by a complex systemic inflammatory response, endothelial dysfunction, and alterations in the coagulation system, which lead to perturbations in the delivery of oxygen and metabolic substrates to the tissues, end-organ dysfunction, and ultimately death. Oxidative stress plays a crucial role as both a promoter and mediator of the systemic inflammatory response, suggesting potential targets for the treatment of critically ill children with the sepsis syndrome. Herein, we will provide a brief review of the role of oxidative and nitrosative stress in the pathophysiology of sepsis.

Sepsis refers to a systemic inflammatory response syndrome resulting from a microbial infection. The inflammatory response is partly mediated by innate immune cells (such as macrophages, monocytes and neutrophils), which not only ingest and eliminate invading pathogens but also initiate an inflammatory response upon recognition of pathogen-associated molecular patterns (PAMPs). The prevailing theories of sepsis as a dysregulated inflammatory response, as manifested by excessive release of inflammatory mediators such as tumour necrosis factor and high-mobility group box 1 protein (HMGB1), are supported by extensive studies employing animal models of sepsis. Here we review emerging evidence that support extracellular HMGB1 as a late mediator of experimental sepsis, and discuss the therapeutic potential of several HMGB1-targeting agents (including neutralising antibodies and steroid-like tanshinones) in experimental sepsis.

Protein toxins are important virulence factors contributing to neonatal sepsis. The major pathogens of neonatal sepsis, group B Streptococci, Escherichia coli, Listeria monocytogenes, and Staphylococcus aureus, secrete toxins of different molecular nature, which are key for defining the disease. Amongst these toxins are pore-forming exotoxins that are expressed as soluble monomers prior to engagement of the target cell membrane with subsequent formation of an aqueous membrane pore. Membrane pore formation is not only a means for immediate lysis of the targeted cell but also a general mechanism that contributes to penetration of epithelial barriers and evasion of the immune system, thus creating survival niches for the pathogens. Pore-forming toxins, however, can also contribute to the induction of inflammation and hence to the manifestation of sepsis. Clearly, pore-forming toxins are not the sole factors that drive sepsis progression, but they often act in concert with other bacterial effectors, especially in the initial stages of neonatal sepsis manifestation.

Medical family therapy (MedFT) has gained momentum as a framework in healthcare for individuals and families. However, little is known about what background training and clinical experiences Medical Family Therapists (MedFTs) have in everyday practice. This study investigated the clinical training of MedFTs and their practices in a variety of care settings. A survey was completed by 80 participants who use a MedFT framework in practice, with descriptive data on curriculum, clinical training, and treatment characteristics. Results reflect that many MedFTs lack formal coursework in key content areas of their graduate training and work primarily with psychological and relational concerns. Future research is needed to explore how MedFTs practice around specific mental health and chronic health conditions.
Canadian ethicists have a long legacy of leadership in advocating for standards and quality in healthcare ethics. Continuing this tradition, a grassroots organization of practicing healthcare ethicists (PHEs) concerned about the lack of standardization in the field recently formed to explore potential options related to professionalization. This group calls itself "practicing healthcare ethicists exploring professionalization" (PHEEP). This paper provides a description of the process by which PHEEP has begun to engage the Canadian PHE community in the development of practice standards and related projects. By making our process and its ethical and cultural underpinnings transparent, we hope to prompt PHEs around the world to reflect on the importance of context, process and principles (not just outcomes) in the exploration of and possible movement towards professionalization. By sharing some of our key successes and challenges, we also hope to inspire our colleagues to recognize the value in developing practice standards and to contribute to this endeavor.

Sepsis is defined as life-threatening organ dysfunction caused by dysregulated host responses to infection (Third International Consensus definition for Sepsis and septic shock). Despite decades of research, sepsis remains the leading cause of death in intensive care units. More than 40 clinical trials, most of which have targeted the sepsis-associated pro-inflammatory response, have failed. Thus, antibiotics and fluid resuscitation remain the mainstays of supportive care and there is intense need to discover and develop novel, targeted therapies to treat sepsis. Both pre-clinical and clinical studies over the past decade demonstrate unequivocally that sepsis not only causes hyper-inflammation, but also leads to simultaneous adaptive immune system dysfunction and impaired antimicrobial immunity. Evidences for immunosuppression include immune cell depletion (T cells most affected), compromised T cell effector functions, T cell exhaustion, impaired antigen presentation, increased susceptibility to opportunistic nosocomial infections, dysregulated cytokine secretion, and reactivation of latent viruses. Therefore, targeting immunosuppression provides a logical approach to treat protracted sepsis. Numerous pre-clinical studies using immunomodulatory agents such as interleukin-7, anti-programmed cell death 1 antibody (anti-PD-1), anti-programmed cell death 1 ligand antibody (anti-PD-L1), and others have demonstrated reversal of T cell dysfunction and improved survival. Therefore, identifying immunosuppressed patients with the help of specific biomarkers and administering specific immunomodulators holds significant potential for sepsis therapy in the future. This review focusses on T cell dysfunction during sepsis and discusses the potential immunotherapeutic agents to boost T cell function during sepsis and improve host resistance to infection.

Sepsis is a subtype of systemic inflammatory response syndrome (SIRS), which is characterized by infection. Circulating microRNAs (miRNAs), including miR-150, miR-146a and miR-223, are potential biomarkers of sepsis. In this study, we demonstrated that measuring the relative expression of miR-146a/U6 in plasma, using the 2(-ΔΔCt) method, provides a method for differentiating between sepsis and non-sepsis-SIRS. We observed a significant increase in miR-146a expression in the initial cohort of 6 non-sepsis-SIRS patients compared to the 4 sepsis patients (P=0.01) and in the second cohort of 8 non-sepsis-SIRS patients compared to the 10 sepsis patients (P=0.027). Additionally, we identified that sodium citrate and ethylenediaminetetraacetic acid (EDTA) K2 may be used as anticoagulant reagents. Generation of a standard curve is not necessary in these diagnostic tests, unless the standard of normalization is carefully selected. Thus we provide more detailed guidance for the clinical use of circulating miRNA biomarkers.

Magnesium (Mg), also known as "the forgotten electrolyte", is the fourth most abundant cation overall and the second most abundant intracellular cation in the body. Mg deficiency has been implicated in the pathophysiology of many diseases. This article is a review of the literature regarding Mg abnormalities with emphasis on the implications of hypomagnesemia in critical illness and on treatment options for hypomagnesemia in critically ill patients with sepsis. Hypomagnesemia is common in critically ill patients, and there is strong, consistent clinical evidence, largely from observational studies, showing that hypomagnesemia is significantly associated with increased need for mechanical ventilation, prolonged ICU stay and increased mortality. Although the mechanism linking hypomagnesemia with poor clinical outcomes is not known, experimental data suggest mechanisms contributing to such outcomes. However, at the present time, there is no clear evidence that magnesium supplementation improves outcomes in critically ill patients with hypomagnesemia. Large, well-designed clinical trials are needed to evaluate the role of magnesium therapy for improving outcomes in critically ill patients with sepsis.

Rats were whole-body irradiated with 8-MeV cyclotron-produced neutrons and /sup 137/Cs ..gamma.. rays to study the role of enteric bacteria and endotoxin in the intestinal radiation syndrome. Decrease in intestinal weight was used as an index of radiation-induced breakdown of the mucosa. Neutron and ..gamma..-ray doses that were sublethal for intestinal death resulted in a dose-dependent decrease in intestinal weight, reaching minimal values 2 to 3 days after exposure, followed by recovery within 5 days after irradiation. Neutron and photon doses that caused intestinal death resulted in greater mucosal breakdown with little or no evidence of mucosal recovery. The presence of fluid in the intestine and diarrhea, but not bacteremia or endotoxemia, were related to mucosal breakdown and recovery. Neither sepsis nor endotoxin could be detected in liver samples taken at autopsy from animals which died a short time earlier from intestinal injury. These results suggest that overt sepsis and endotoxemia do not play a significant role in the intestinal radiation syndrome.

Objectives A sense of calling is a concept with religious and theological roots; however, it is unclear whether contemporary physicians in the United States still embrace this concept in their practice of medicine. This study assesses the association between religious characteristics and endorsing a sense of calling among practicing primary care physicians (PCPs) and psychiatrists. Methods In 2009, we surveyed a stratified random sample of 2016 PCPs and psychiatrists in the United States. Physicians were asked whether they agreed with the statement, “For me, the practice of medicine is a calling.” Primary predictors included demographic and self-reported religious characteristics, including attendance, affiliation, importance of religion, intrinsic religiosity) and spirituality. Results Among eligible respondents, the response rate was 63% (896/1427) for PCPs and 64% (312/487) for psychiatrists. A total of 40% of PCPs and 42% of psychiatrists endorsed a strong sense of calling. PCPs and psychiatrists who were more spiritual and/or religious as assessed by all four measures were more likely to report a strong sense of calling in the practice of medicine. Nearly half of Muslim (46%) and Catholic (45%) PCPs and the majority of evangelical Protestant PCPs (60%) report a strong sense of calling in their practice, and PCPs with these affiliations were more likely to endorse a strong sense of calling than those with no affiliation (26%, bivariate P < 0.001). We found similar trends for psychiatrists. Conclusions In this national study of PCPs and psychiatrists, we found that PCPs who considered themselves religious were more likely to report a strong sense of calling in the practice of medicine. Although this cross-sectional study cannot be used to make definitive causal inferences between religion and developing a strong sense of calling, PCPs who considered themselves religious are more likely to embrace the concept of calling in their practice of medicine.

The purpose of this study is to comparatively analyze the ethnomedicinal practices on gastrointestinal disorders within communities in Jirisan National Park, Gayasan National Park, and Hallasan National Park of Korea. Data was collected through participant observations and indepth interviews with semistructured questionnaires. Methods for comparative analysis were accomplished using the informant consensus factor, fidelity level, and internetwork analysis. A total of 490 ethnomedicinal practices recorded from the communities were classified into 110 families, 176 genera, and 220 species that included plants, animals, fungi, and alga. The informant consensus factor values in the disorder categories were enteritis, and gastralgia (1.0), followed by indigestion (0.94), constipation (0.93), and abdominal pain and gastroenteric trouble (0.92). In terms of fidelity levels, 71 plant species showed fidelity levels of 100%. The internetwork analysis between disorders and all medicinal species are grouped in the center by the four categories of indigestion, diarrhea, abdominal pain, and gastroenteric trouble, respectively. Regarding the research method of this study, the comparative analysis methods will contribute to the availability of orally transmitted ethnomedicinal knowledge. Among the methods of analysis, the use of internetwork analysis as a tool for analysis in this study provides imperative internetwork maps between gastrointestinal disorders and medicinal species.

In the past thirty to forty years, new clinically oriented roles have emerged for pharmacists, commensurate with their training and consistent with national goals to improve the safety of, access to, and cost of health care. Pharmacists in all settings spend an increasing portion of their time filling these roles, as evidenced more recently in the community pharmacy sector by the success of pharmacy-based immunization programs and such new venues as retail pharmacy clinics. Pharmacy technicians are also assuming new roles and responsibilities, providing services previously delivered only by pharmacists. However, both trends are hindered by current policy. Of particular concern are inconsistent state-level scope-of-practice laws, the lack of mechanisms to reimburse pharmacists for services provided, the need to recognize pharmacists as health care providers, and the need to establish national standards for the preparation of pharmacy technicians. The optimal deployment of the pharmacy workforce will require the closer alignment of pharmacy practice and policy with each other and with the nation's health care priorities.

Various types of teaching and learning strategies can be effectively employed to assist students' professional development in ethical decision-making skills. To be prepared to act as a moral agent in clinical practice, a terminal goal upon completion of the baccalaureate program is the student's ability to develop and consistently use a systematic approach/framework when confronted by an ethical dilemma. Eleven skill steps not necessarily exclusive or in sequence were outlined as selected activities that can be considered for the ethical decision process. Specific ethical issues that are germane and applicable to many patient care situations were investigated and identified as frequently occurring in clinical practice. Course work about these issues prior to completion of their nursing programs may be beneficial in preparing students with basic knowledge and skill about them as they enter or return to clinical practice.

Heart disease is among the leading causes of death in all populations. Cardiac dysfunctions are major complications in patients with advanced viral or bacterial infection, severe trauma and burns accompanied with multiple organ failure - collectively known as systemic inflammatory response syndrome (SIRS). SIRS, which is often subsequent to sepsis, is clinically featured by hypotension, tachypnea, hypo- or hyperthermia, leukocytosis and myocardial dysfunction. The striking association between inflammation and cardiac dysfunction not only prognoses likelihood of survival in patients with SIRS but also prompts the necessity of understanding the pathophysiology of cardiac dysfunction in SIRS, so that effective therapeutic regimen may be identified. Compelling evidence has shown significant and independent link among inflammation, sepsis, insulin resistance and cardiac dysfunction. Several cytokine signaling molecules have been speculated to play important roles in the onset of cardiac dysfunction under SIRS including endothelin-1 and toll-like receptor. Involvement of these pathways in cardiac dysfunction has been convincingly validated with transgenic studies. Nevertheless, the precise mechanism of action underscoring inflammation-induced cardiac contractile dysfunction is far from being clear. Given the substantial impact of inflammation and SIRS on health care, ecosystems and national economy, it is imperative to understand the cellular mechanisms responsible for cardiac contractile dysfunction under inflammation and sepsis so that new and effective therapeutic strategy against such devastating heart problems may be developed.

Objective The study aimed to construct and manage an acute respiratory distress syndrome (ARDS)/sepsis registry that can be used for data warehousing and clinical research. Methods The workflow methodology and software solution of research electronic data capture (REDCap) was used to construct the ARDS/sepsis registry. Clinical data from ARDS and sepsis patients registered to the intensive care unit (ICU) of our hospital formed the registry. These data were converted to the electronic case report form (eCRF) format used in REDCap by trained medical staff. Data validation, quality control, and database management were conducted to ensure data integrity. Results The clinical data of 67 patients registered to the ICU between June 2013 and December 2013 were analyzed. Of the 67 patients, 45 (67.2%) were classified as sepsis, 14 (20.9%) as ARDS, and eight (11.9%) as sepsis-associated ARDS. The patients’ information, comprising demographic characteristics, medical history, clinical interventions, daily assessment, clinical outcome, and follow-up data, was properly managed and safely stored in the ARDS/sepsis registry. Data efficiency was guaranteed by performing data collection and data entry twice weekly and every two weeks, respectively. Conclusions The ARDS/sepsis database that we constructed and manage with REDCap in the ICU can provide a solid foundation for translational research on the clinical data of interest, and a model for development of other medical registries in the future.

Neonatal sepsis is the third leading cause of neonatal mortality and a major public health problem, especially in developing countries. Although recent medical advances have improved neonatal care, many challenges remain in the diagnosis and management of neonatal infections. The diagnosis of neonatal sepsis is complicated by the frequent presence of noninfectious conditions that resemble sepsis, especially in preterm infants, and by the absence of optimal diagnostic tests. Since neonatal sepsis is a high-risk disease, especially in preterm infants, clinicians are compelled to empirically administer antibiotics to infants with risk factors and/or signs of suspected sepsis. Unfortunately, both broad-spectrum antibiotics and prolonged treatment with empirical antibiotics are associated with adverse outcomes and increase antimicrobial resistance rates. Given the high incidence and mortality of sepsis in preterm infants and its long-term consequences on growth and development, efforts to reduce the rates of infection in this vulnerable population are one of the most important interventions in neonatal care. In this review, we discuss the most common questions and challenges in the diagnosis and management of neonatal sepsis, with a focus on developing countries. PMID:25604489

Neonatal sepsis continues to be a common and significant health care burden, especially in very-low-birth-weight infants (VLBW<1500 g). Though intrapartum antibiotic prophylaxis has decreased the incidence of early-onset group B streptococcal infection dramatically, it still remains a major cause of neonatal sepsis. Moreover, some studies among VLBW preterm infants have shown an increase in early-onset sepsis caused by Escherichia coli. As the signs and symptoms of neonatal sepsis are nonspecific, early diagnosis and prompt treatment remains a challenge. There have been a myriad of studies on various diagnostic markers like hematological indices, acute phase reactants, C-reactive protein, procalcitonin, cytokines, and cell surface markers among others. Nonetheless, further research is needed to identify a biomarker with high diagnostic accuracy and validity. Some of the newer markers like inter α inhibitor proteins have shown promising results thereby potentially aiding in early detection of neonates with sepsis. In order to decrease the widespread, prolonged use of unnecessary antibiotics and improve the outcome of the infants with sepsis, reliable identification of sepsis at an earlier stage is paramount.

Sepsis affects millions of people every year, many of whom will die. In contrast to current survival prediction models for sepsis patients that primarily are based on data from within-admission clinical measurements (e.g. vital parameters and blood values), we aim for using the full disease history to predict sepsis mortality. We benefit from data in electronic medical records covering all hospital encounters in Denmark from 1996 to 2014. This data set included 6.6 million patients of whom almost 120,000 were diagnosed with the ICD-10 code: A41 ‘Other sepsis’. Interestingly, patients following recurrent trajectories of time-ordered co-morbidities had significantly increased sepsis mortality compared to those who did not follow a trajectory. We identified trajectories which significantly altered sepsis mortality, and found three major starting points in a combined temporal sepsis network: Alcohol abuse, Diabetes and Cardio-vascular diagnoses. Many cancers also increased sepsis mortality. Using the trajectory based stratification model we explain contradictory reports in relation to diabetes that recently have appeared in the literature. Finally, we compared the predictive power using 18.5 years of disease history to scoring based on within-admission clinical measurements emphasizing the value of long term data in novel patient scores that combine the two types of data.

Sepsis is a leading cause of death in the United States and worldwide. Early recognition and effective management are essential for improved outcome. However, early recognition is impeded by lack of clinically utilized biomarkers. Complement factors play important roles in the mechanisms leading to sepsis and can potentially serve as early markers of sepsis and of sepsis severity and outcome. This review provides a synopsis of recent animal and clinical studies of the role of complement factors in sepsis development, together with their potential as disease markers. In addition, new results from our laboratory are presented regarding the involvement of the complement factor, mannose-binding lectin, in septic shock patients. Future clinical studies are needed to obtain the complete profiles of complement factors/their activated products during the course of sepsis development. We anticipate that the results of these studies will lead to a multipanel set of sepsis biomarkers which, along with currently used laboratory tests, will facilitate earlier diagnosis, timely treatment, and improved outcome.

Introduction. Severe sepsis in humans may be related to an underlying profound immune suppressive state. We investigated the link between gene expression of immune regulatory cytokines and the range of illness severity in patients with infection and severe sepsis. Methods. A prospective observational study included 54 ICU patients with severe sepsis, 53 patients with infection without organ failure, and 20 healthy controls. Gene expression in peripheral blood mononuclear cells (PBMC) was measured using real-time polymerase chain reaction. Results. Infection differed from health by decreased expression of the IL2, and IL23 and greater expression of IL10 and IL27. Severe sepsis differed from infection by having decreased IL7, IL23, IFNγ, and TNFα gene expression. An algorithm utilising mRNA copy number for TNFα, IFNγ, IL7, IL10, and IL23 accurately distinguished sepsis from severe sepsis with a receiver operator characteristic value of 0.88. Gene expression was similar with gram-positive and gram-negative infection and was similar following medical and surgical severe sepsis. Severity of organ failure was associated with serum IL6 protein levels but not with any index of cytokine gene expression in PBMCs. Conclusions. Immune regulatory cytokine gene expression in PBMC provides a robust method of modelling patients' response to infection. PMID:23935244

The continuous development of resuscitation techniques and intensive care reduced the mortality rate induced by the initial shock in burn patients and, currently, infections (especially sepsis) are the main causes of mortality of these patients. The misuse of antimicrobial agents is strongly related to antimicrobial and adverse patient outcomes, development of microbial resistance and increased healthcare-related costs. To overcome these risks, antimicrobial stewardship is mandatory and biomarkers are useful to avoid unnecessary medical prescription, to monitor antimicrobial therapy and to support the decision of its stop. Among a large array of laboratory tests, procalcitonin (PCT) emerged as the leading biomarker to accurately and time-effectively indicate the presence of systemic infection. In the presence of systemic infection, PCT blood levels undergo a sudden and dramatic increase, following the course of the infection, and quickly subside after the control of the septic process. This work is a meta-analysis on PCT performance as a biomarker for sepsis. This meta–analysis showed that overall pooled area under the curve (AUC) is 0.83 (95% CI = 0.76 to 0.90); the estimated cut-off is 1.47 ng/mL. The overall sepsis effect in PCT levels is significant and strong (Cohen's d is 2.1 and 95% CI = 1.1 to 3.2). This meta–analysis showed PCT may be considered as a biomarker with a strong diagnostic ability to discriminate between the septic from the non-septic burn patients. Thus, this work encourages the determination of PCT levels in clinical practice for the management of these patients, in order to timely identify the susceptibility to sepsis and to initiate the antimicrobial therapy, improving the patients’ outcomes.

The first national audit for rheumatoid and early inflammatory arthritis has benchmarked care for the first three months of follow up activity from first presentation to a rheumatology service. Access to care, management of early RA and support for self care were measured against NICE quality standards and impact of early arthritis and experience of care were measured using patient reported outcome and experience measures. The results demonstrate delays in referral and accessing specialist care and the need for service improvement in treating to target, suppression of high levels of disease activity and support for self-care. Improvements in patient -reported outcomes within three months and high levels of overall satisfaction were reported but these results were affected by low response rates. Here we present a summary of the national data from the audit and discuss the implications for nursing practice. PMID:27281595

The Chief Nursing Officers (CNOs) of the University HealthSystems Consortium (UHC) of Academic Hospitals desired to increase the numbers of baccalaureate graduate nurses hired by their facilities and provide a more consistent, uniform transition into practice for these graduate nurses. A partnership between the UHC CNOs and the American Association of Colleges of Nursing (AACN) led to establishing a National Post-Baccalaureate Graduate Nurse Residency Program. The structure, curriculum, and outcomes measures were developed and the program was implemented, with growth from six original pilot sites to 34 academic hospitals. Outcomes from the first year of program operation at these six sites show a high rate of retention, decreased stress by graduate nurses over time, improved organization and prioritization of care, and increased satisfaction in the first year of practice.

The U.S. National Institute for Occupational Safety and Health (NIOSH) conducts research to improve and protect the health and safety of workers. This paper describes the experience of the NIOSH Construction Program with two recent program planning initiatives intended to improve the program: (a) an independent external review of work over the past decade and (b) the development of strategic goals organized into a "National Construction Agenda" to guide a decade of future work. These goals, developed with input from construction industry stakeholders and researchers, are a part of the NIOSH National Occupational Research Agenda (NORA) initiative. The NORA goals are intended to provide an ambitious set of goals for all construction stakeholders to work together on. Both efforts relate to insuring the relevance and impact of research, reflecting an emerging policy perspective that research programs should be judged not just by the quality and quantity of science produced, but by the industry impact and tangible benefit resulting from the research. This paper describes how views on research planning have evolved to incorporate lessons learned about how research leads to improved safety and health for workers. It also describes the process used to develop the goals and the resulting strategic and intermediate goals that comprise the National Construction Agenda.

The National Disease Management Guideline for Asthma was developed through a consensus process that involved different medical societies, thus constituting a novelty in the improvement of the care for asthma patients in Germany. The German Association of General Practitioners (DEGAM) also participated in the development of the asthma guideline. The implementability of this new guideline in general practice will be discussed on the basis of the chapters that are most important to primary care physicians. The guideline offers many relevant aspects for the management of asthma in general practice. In future editions, the levels of evidence underlying the statements about diagnosis and therapy should be more elaborate, thus providing more concise decision aids for physicians in daily practice. In particular, the implementation aids on the guideline's website could be used to translate the content of the guidelines into practice. Continuous quality improvement and the further development of the implementation process would be most important in overcoming the cross-sectoral barriers of the German healthcare system and thus optimizing the quality of care.

Objective Determine school characteristics associated with healthy/unhealthy foodservice offerings or healthy food preparation practices. Design Retrospective analysis of cross-sectional data. Setting Nationally representative sample of public and private elementary, middle and high schools. Participants 526 and 520 schools with valid data from the 2006 School Health Policies and Practices Study (SHPPS) Food Service School Questionnaire. Main Outcome Measure(s) Scores for healthy/unhealthy foodservice offerings and healthy food preparation practices. Analysis Multivariable regression to determine significant associations among school characteristics and offerings/preparation practices. Results Public schools and schools participating in USDA Team Nutrition reported more healthy offerings and preparation than private or non-participating schools, respectively. Elementary schools reported less unhealthy offerings than middle or high schools; middle schools reported less unhealthy offerings than high schools. Schools requiring foodservice managers to have a college education reported more healthy preparation while those requiring completion of a foodservice training program reported less unhealthy offerings and more healthy preparation than schools without these requirements. Conclusions and Implications Results suggest the school nutrition environment may be improved by requiring foodservice managers to hold a nutrition-related college degree and/or successfully pass a foodservice training program, and by participating in a school-based nutrition program, such as USDA Team Nutrition.

Colloids are frequently used for fluid expansion in the intensive care unit, although its use on several clinical scenarios remains unproven of any relevant clinical benefit. The purpose of this article was to carry out a narrative review regarding the safety and efficacy of colloids in patients with sepsis and septic shock, with emphasis on the most commonly used colloids, albumin and starches. Colloids are effective fluid expanders and are able to restore the hemodynamic profile with less total volume than crystalloids. These properties appear to be preserved even in patients with sepsis with increased capillary permeability. However, some colloids are associated with renal impairment and coagulation abnormalities. Starch use was associated with increased mortality in two large clinical trials. Also, starches probably have significant renal adverse effects and may be related to more need for renal replacement therapy in severe sepsis. Albumin is the only colloid that has been shown safe in patients with sepsis and that may be associated with improved outcomes on specific subpopulations. No trial so far found any robust clinical end point favoring colloid use in patients with sepsis. Because there is no proven benefit of the use of most colloids in patients with sepsis, its use should not be encouraged outside clinical trials. Albumin is the only colloid solution that has proven to be safe, and its use may be considered on hypoalbuminemic patients with sepsis. Nevertheless, there are no robust data to recommend routine albumin administration in sepsis. Starch use should be avoided in patients with sepsis because of the recent findings of a multicenter randomized study until further evidence is available.

Sepsis is a major healthcare problem and leading cause of death worldwide. UK hospital mortality statistics and payments for patient episodes of care are calculated on clinical coding data. The accuracy of these data depends on the quality of coding. This study aimed to investigate whether patients with significant bacteraemia are coded for sepsis and to estimate the financial costs of miscoding. Of 54 patients over a one-month period with a significant bacteraemia, only 19% had been coded for sepsis. This is likely to lead to falsely high calculated hospital mortality. Furthermore, this resulted in an underpayment of £21,000 for one month alone.

Sepsis in older adults has many challenges that affect rate of septic diagnosis, treatment, and monitoring parameters. Numerous age-related changes and comorbidities contribute to increased risk of infections in older adults, but also atypical symptomatology that delays diagnosis. Due to various pharmacokinetic/pharmacodynamic changes in the older adult, medications are absorbed, metabolized, and eliminated at different rates as compared to younger adults, which increases risk of adverse drug reactions due to use of drug therapy needed for sepsis management. This review provides information to aid in diagnosis as well as offers recommendations for monitoring and treating sepsis in the older adult population. PMID:26687340

Sepsis is a stressful physical condition, and at the acute phase, overstimulation of the sympathetic nervous system may occur; these events have the potential to induce cardiomyopathy. Takotsubo cardiomyopathy (TTC) is a form of catecholamine-induced cardiomyopathy, which occurs very rarely in sepsis. However, TTC management in critically ill patients with sepsis may be challenging because the use of exogenous catecholamines for circulatory support might augment further TTC. Herein, we report a rare case of TTC after urosepsis; and we point out that cardiac function may improve after catecholamine withdrawal and the application of calcium channel sensitizer levosimendan.

In 2001, Rivers and colleagues published a randomized controlled trial of early goal-directed therapy (EGDT) for the treatment of sepsis. More than a decade later, it remains a landmark achievement. The study proved the benefits of early aggressive treatment of sepsis. However, many questions remain about specific aspects of the complex EGDT algorithm. Recently, 3 large trials attempted to replicate these results. None of the studies demonstrated a benefit of an EGDT protocol for sepsis. This review explores the physiologic basis of goal-directed therapy, including the hemodynamic targets and the therapeutic interventions. An understanding of the physiologic basis of EGDT helps reconcile the results of the clinical trials.
The immediate metabolic response to a septic challenge is probably adaptive, meaning that nutritional interference, mainly via the parenteral route, during this early phase of instability can do more harm than good. During the later phases, a gradual increase in enteral nutrition, at the expense of parenteral nutrition, combined with the administration of nutraceuticals such as glutamine and omega-3 fatty acids, can counteract wasting and modulate the complex inflammatory response and immunosuppression associated with sepsis. In these times of scarce resources, there is an urgent need to clearly document the efficacy of immuno/pharmaconutrients, individually and in combination, enterally or parenterally, before proposing them for routine management of septic patients in the intensive care unit.

Despite concerted international efforts, mortality from neonatal infections remains unacceptably high in some areas of the world, particularly for premature infants. Recent developments in flow cytometry and next-generation sequencing technologies have led to major discoveries over the past few years, providing a more integrated understanding of the developing human immune system in the context of its microbial environment. We review these recent findings, focusing on how in human newborns incomplete maturation of the immune system before a full term of gestation impacts on their vulnerability to infection. We also discuss some of the clinical implications of this research in guiding the design of more-accurate age-adapted diagnostic and preventive strategies for neonatal sepsis. PMID:26993220

Sepsis is a clinical entity in which complex inflammatory and physiological processes are mobilized, not only across a range of cellular and molecular interactions, but also in clinically relevant physiological signals accessible at the bedside. There is a need for a mechanistic understanding that links the clinical phenomenon of physiologic variability with the underlying patterns of the biology of inflammation, and we assert that this can be facilitated through the use of dynamic mathematical and computational modeling. An iterative approach of laboratory experimentation and mathematical/computational modeling has the potential to integrate cellular biology, physiology, control theory, and systems engineering across biological scales, yielding insights into the control structures that govern mechanisms by which phenomena, detected as biological patterns, are produced. This approach can represent hypotheses in the formal language of mathematics and computation, and link behaviors that cross scales and domains, thereby offering the opportunity to better explain, diagnose, and intervene in the care of the septic patient.
In this decade, the molecular mechanism of sepsis has been strikingly clarified. Especially, the identification of toll-like receptors as the pivotal molecules for the recognition of the stimulation of the inflammatory products of microorganisms has contributed to the elucidation of intracellular signaling pathways which result in severe systemic inflammatory response in sepsis. The production and release of a variety of pro-inflammatory mediators have been found to be associated with severe systemic inflammation and multiple organ dysfunction syndrome (MODS). In the pathophysiology of the development of MODS in sepsis, the disturbance of peripheral microcirculation, the insult of tissues and cells by leukocytes and activated complements and the augmentation of the disorder of fibrinolytic and coagulation systems, which often results in the outbreak of disseminated intravascular coagulopathy (DIC), will be critically involved. Despite of the advance in the basic research regarding molecular pathophysiology of sepsis, sepsis is still accompanied by high mortality in clinical settings. Almost all clinical trials targeting sepsis-associated mediators have failed, except the substitution therapy of activated protein C. However, further trials based on the basic findings, including the therapies targeting the multiple mediators, will contribute to the improvement of outcome of clinical sepsis. ple organ dysfunction syndrome (MODS), pro-inflammatory mediator, disseminated intravascular coagulopathy (DIC).

Homework assignments have been studied extensively in psychotherapy research, but there is little data on the way in which homework is transferred to clinical practice. A survey was conducted of 827 practicing psychologists nationwide regarding their use and attitudes toward homework. Overall, 68% of the present sample indicated that they "often" or "almost always" used homework assignments. Factor analysis revealed that practitioners have a range of attitudes that can be classified as reflecting the notion that homework has (a) a negative impact on in-session therapeutic work and (b) a positive effect on therapy outcomes. More positive attitudes were reported among those with a cognitive-behavioral theoretical orientation. Nevertheless, the use of homework among psychodynamic/analytic practitioners reported in the present sample was unexpected and suggests that theoretical and empirical work is required to examine homework's effects in a range of psychotherapy approaches.

This study evaluated the accuracy and utility of the In-111 labeled WBC imaging in a series of patients who were suspected of having musculoskeletal sepsis. The labeling of the WBCs was patterned after a method previously described, in which the WBCs are labeled with In-111 oxine in plasma. The WBCs from 100 ml of blood are separated and incubated with In-111 oxine complex, and then 500 ..mu..Ci. of the labeled cells were reinjected into the patient. Images of the areas in question were obtained at 24 hrs. In some instances, 48 hour images were also obtained. Images were interpreted using consistent criteria. Forty imaging procedures were done on 39 patients. These included 39 total joint protheses, and 17 other images to evaluate possible osteomyelitis, septic arthritis or deep abscesses. Of these studies, 15 were positive, and 42 negative. The findings were then correlated with operative culture and pathology in 21, aspiration cultures and gram stains in 14, and with clinical findings in the remaining 21. This correlation showed 41 true negatives, 12 true positives, 1 false negative, and 2 false positives. The sensitivity was 92.9% and the specificity was 95.2%l. The false negative occurred in a patient on chronic suppressive antibiotic therapy for an infected total hip replacement. The false positive images occurred in a patient with active rheumatoid arthritis and in a patient imaged one month post operative placement of the prosthesis. These images were very useful in several septic patients who had many possible sites of infection. The authors conclude that In-III imaging is an accurate and useful non-invasive method of evaluating musculoskeletal sepsis.

Amino acid uptake in vivo was determined in soleus (SOL) muscle, diaphragm, heart, and liver following intravenous injection of [3H]-alpha-amino-isobutyric acid ([3H]-AIB) in rats made septic by cecal ligation and puncture (CLP) and in sham-operated controls. Muscle amino acid transport was also measured in vitro by determining uptake of [3H]-AIB in incubated extensor digitorum longus (EDL) and SOL muscles. Results were expressed as distribution ratio between [3H]-AIB in intracellular and extracellular fluid. AIB uptake in vivo was reduced by 90% in SOL and cardiac muscle and by 45% in diaphragm 16 hours after CLP. In contrast, AIB uptake by liver was almost four times higher in septic than in control animals. AIB uptake in vitro was reduced by 18% in EDL 8 hours after CLP but was not significantly altered in SOL at the same time point. Sixteen hours after CLP, AIB uptake was significantly reduced in both muscles, i.e., by 17% in EDL and by 65% in SOL. When muscles from untreated rats were incubated in the presence of plasma from septic animals (16 hours CLP) or from animals injected with endotoxin (2 mg/kg body weight), AIB uptake was reduced. Addition of endotoxin in vitro (2-200 micrograms/ml) to incubated muscles did not affect AIB uptake. The results suggest that sepsis leads to marked impairment of amino acid transport system A in muscle and that this impairment is mediated by a circulating factor that is not endotoxin. Reduced uptake of amino acids by skeletal muscle during sepsis may divert amino acids to the liver for increased gluconeogenesis and protein synthesis. PMID:3963895
Background: Leadership is considered a professional obligation for all pharmacists. It is important to integrate leadership training in residency programs to meet the leadership needs and requirements of the profession. Objective: To evaluate the importance of leadership development during postgraduate year 1 (PGY1) pharmacy practice residency training as perceived by new practitioners. Methods: A 15-question online survey was distributed to residency-trained new practitioners to assess (1) amount of time dedicated to leadership training during residency training, (2) different leadership tools utilized, (3) residents’ participation in various committees or councils, (4) perceived benefit of increased leadership training, (5) importance of having a mentor, (6) understanding of the residency organization’s strategic objectives, (7) discussion of Pharmacy Practice Model Initiative (PPMI) during residency training, and (8) adequacy of leadership training in preparation to become a pharmacy practice leader. Results: Although the majority of resident respondents had less than 20% of their residency devoted to leadership, nearly all survey participants acknowledged that leadership is an important component of PGY1 residency training. Residents agreed that their residency experience would have benefited from increased leadership opportunities. Most residents were knowledgeable about their organization’s strategic objectives but did not have a full understanding of pharmacy initiatives such as the PPMI. Conclusion: Feedback from residents indicates that an optimal dedication to leadership training would range between 20% and 30% of the residency year. Increased focus on PPMI, mentorship, and expanded use of leadership tools can serve as a way to help meet the future leadership needs of the pharmacy profession and help to better prepare residents to become pharmacy practice leaders.

Because forensic medicine workers have a greater occupational risk for infectious diseases, strict rules and measures against infections must be implemented at every stage of forensic medicine practices. In this study, we aim to evaluate the infection control implementations in forensic medicine practices in Turkey.A questionnaire survey was mailed to forensic medicine specialists and residents between April and June 2005. The questionnaire consisted of 36 questions whose designed was based on standard precautions and protective barriers against infectious risks.In all, 111 doctors from 27 different cities responded to the questionnaire. Of those doctors who responded, 43.2% reported performing external examination anywhere. The percentage of doctors performing external examinations who regularly wore gloves, masks, and gowns, and washed hands with a disinfectant were 81.5%, 24.7%, 30.9%, and 81.5%, respectively. The percentage of doctors performing autopsies who regularly wore masks, protective eye-wear, gloves, special gloves, and special boots were 59.6%, 10.6%, 98.9%, 71.3%, and 36.2%, respectively. Only 2 negative pressure rooms were reported.According to these results, precautionary measures against infectious risks in forensic medicine practice in our country are insufficient. Conditions to facilitate and to improve the compliance with infection control procedures must be prepared.

Concerns of violence in hospitals warrant examination of current hospital security practices. Cross-sectional survey data were collected from members of a health care security and safety association to examine the type of personnel serving as security in hospitals, their policies and practices related to training and weapon/restraint tool carrying/use, and the broader context in which security personnel work to maintain staff and patient safety, with an emphasis on workplace violence prevention and mitigation. Data pertaining to 340 hospitals suggest security personnel were typically non-sworn officers directly employed (72%) by hospitals. Available tools included handcuffs (96%), batons (56%), oleoresin capsicum products (e.g., pepper spray; 52%), hand guns (52%), conducted electrical weapons (e.g., TASERs®; 47%), and K9 units (12%). Current workplace violence prevention policy components, as well as recommendations to improve hospital security practices, aligned with Occupational Safety and Health Administration guidelines. Comprehensive efforts to address the safety and effectiveness of hospital security personnel should consider security personnel's relationships with other hospital work groups and hospitals' focus on patients' safety and satisfaction.

PURPOSE We describe the experience of practices in transitioning toward patient-centered medical homes (PCMHs) in the National Demonstration Project (NDP). METHODS The NDP was launched in June 2006 as the first national test of a model of the PCMH in a diverse sample of 36 family practices, randomized to facilitated and self-directed intervention groups. An independent evaluation team used a multimethod evaluation strategy, analyzing data from direct observation, depth interviews, e-mail streams, medical records, and patient and practice surveys. The evaluation team reviewed data from all practices as they became available and produced interim summaries. Four 2- to 3-day evaluation team retreats were held during which case summaries of all practices were discussed and patterns were described. RESULTS The 6 themes that emerged from the data reflect major shifts in individual and practice roles and identities, as well as changes in practices’ management strategies. The themes are (1) practice adaptive reserve is critical to managing change, (2) developmental pathways to success vary considerably by practice, (3) motivation of key practice members is critical, (4) the larger system can help or hinder, (5) practice transformation is more than a series of changes and requires shifts in roles and mental models, and (6) practice change is enabled by the multiple roles that facilitators play. CONCLUSIONS Transformation to a PCMH requires more than a sequence of discrete changes. The practice transformation process may be fostered by promoting adaptive reserve and local control of the developmental pathway. PMID:20530394
Background Given the acknowledged problems in sepsis diagnosis, we use a novel way with the application of the latent class analysis (LCA) to determine the operative characteristics of C-reactive protein (CRP), D-dimer (DD) and Procalcitonin (PCT) as diagnostic tests for sepsis in patients admitted to hospital care with a presumptive infection. Methods Cross-sectional study to determine the diagnostic accuracy of three biological markers against the gold standard of clinical definition of sepsis provided by an expert committee, and also against the likelihood of sepsis according to LCA. Patients were recruited in the emergency room within 24 hours of hospitalization and were follow-up daily until discharge. Results Among 765 patients, the expert committee classified 505 patients (66%) with sepsis, 112 (15%) with infection but without sepsis and 148 (19%) without infection. The best cut-offs points for CRP, DD, and PCT were 7.8 mg/dl, 1616 ng/ml and 0.3 ng/ml, respectively; but, neither sensitivity nor specificity reach 70% for any biomarker. The LCA analysis with the same three tests identified a “cluster” of 187 patients with several characteristics suggesting a more severe condition as well as better microbiological confirmation. Assuming this subset of patients as the new prevalence of sepsis, the ROC curve analysis identified new cut-off points for the tests and suggesting a better discriminatory ability for PCT with a value of 2 ng/ml. Conclusions Under a “classical” definition of sepsis three typical biomarkers (CRP, PCT and DD) are not capable enough to differentiate septic from non-septic patients in the ER. However, a higher level of PCT discriminates a selected group of patients with severe sepsis. PMID:24050481

Since the advent of highly active antiretroviral therapy in 1996, we have seen dramatic changes in morbi-mortality rates from human immunodeficiency virus-positive patients. If on the one hand, the immunologic preservation-associated with the use of current antiretroviral therapy markedly diminishes the incidence of opportunistic infections, on the other hand it extended life expectancy of human immunodeficiency virus-infected individuals similarly to the general population. However, the management of critically ill human immunodeficiency virus-infected patients remains challenging and troublesome for practicing clinician. Sepsis - a complex systemic inflammatory syndrome in response to infection - is the second leading cause of intensive care unit admission in both human immunodeficiency virus-infected and uninfected populations. Recent data have emerged describing a substantial burden of sepsis in the infected population, in addition, to a much poorer prognosis in this group. Many factors contribute to this outcome, including specific etiologies, patterns of inflammation, underlying immune dysregulation related to chronic human immunodeficiency virus infection and delays in prompt diagnosis and treatment. This brief review explores the impact of sepsis in the context of human immunodeficiency virus infection, and proposes future directions for better management and prevention of human immunodeficiency virus-associated sepsis.
Background Evidence-based practice (EBP) is emphasized to increase the quality of care and patient safety. EBP is often described as a process consisting of distinct activities including, formulating questions, searching for information, compiling the appraised information, implementing evidence, and evaluating the resulting practice. To increase registered nurses’ (RNs’) practice of EBP, variables associated with such activities need to be explored. The aim of the study was to examine individual and organizational factors associated with EBP activities among RNs 2 years post graduation. Methods A cross-sectional design based on a national sample of RNs was used. Data were collected in 2007 from a cohort of RNs, included in the Swedish Longitudinal Analyses of Nursing Education/Employment study. The sample consisted of 1256 RNs (response rate 76%). Of these 987 RNs worked in healthcare at the time of the data collection. Data was self-reported and collected through annual postal surveys. EBP activities were measured using six single items along with instruments measuring individual and work-related variables. Data were analyzed using logistic regression models. Results Associated factors were identified for all six EBP activities. Capability beliefs regarding EBP was a significant factor for all six activities (OR = 2.6 - 7.3). Working in the care of older people was associated with a high extent of practicing four activities (OR = 1.7 - 2.2). Supportive leadership and high collective efficacy were associated with practicing three activities (OR = 1.4 - 2.0). Conclusions To be successful in enhancing EBP among newly graduated RNs, strategies need to incorporate both individually and organizationally directed factors. PMID:23642173

Purpose We recently identified interleukin-27 (IL-27) as a sepsis diagnostic biomarker in children. Here we assess IL-27 as a sepsis diagnostic biomarker in critically ill adults with systemic inflammatory response syndrome (SIRS) and sepsis. Methods IL-27 and procalcitonin (PCT) were measured from plasma samples in three groups: no sepsis (n = 78), pulmonary source of sepsis (n = 66), and non-pulmonary source of sepsis (n = 43). Receiver operating characteristic curves and classification and regression tree methodology were used to evaluate biomarker performance. Results IL-27 did not discriminate effectively between sepsis and sterile SIRS in unselected patients. The highest area under the curve (AUC) was 0.70 (95% C.I. 0.60 – 0.80) for IL-27 in subjects with a non-pulmonary source of sepsis. A decision tree incorporating IL-27, PCT, and age had an AUC of 0.79 (0.71 – 0.87) in subjects with a non-pulmonary source of sepsis. Compared to children with sepsis, adults with sepsis express less IL-27. Conclusions IL-27 performed overall poorly in this cohort as a sepsis diagnostic biomarker. Combining IL-27, PCT, and age reasonably estimated the risk of sepsis in subjects with a non-pulmonary source of sepsis. IL-27 may be a more reliable sepsis diagnostic biomarker in children than in adults. PMID:24848949

Effective solar radiation measurements for research and economic analyses require a strict protocol for maintenance, calibration, and documentation to minimize station down-time and data corruption. The National Renewable Energy Laboratory's Concentrating Solar Power: Best Practices Handbook for the Collection and Use of Solar Resource Data (1) includes guidelines for operating a solar measure-ment station. This paper describes a suite of automated and semi-automated routines based on the best practices hand-book as developed for the National Renewable Energy La-boratory Solar Resource and Meteorological Assessment Project. These routines allow efficient inspection and data flagging to alert operators of conditions that require imme-diate attention. Although the handbook is targeted for con-centrating solar power applications, the quality-assessment procedures described are generic and should benefit many solar measurement applications. The routines use data in one-minute measurement resolution, as suggested by the handbook, but they could be modified for other time scales.

Formal planning for climate change adaptation is emerging rapidly at a range of geo-political scales. This first generation of adaptation plans provides useful information regarding how institutions are framing the issue of adaptation and the range of processes that are recognized as being part of an adaptation response. To better understand adaptation planning among developed nations, a set of 57 adaptation plans from Australia, the United Kingdom and the United States was evaluated against a suite of 19 planning processes identified from existing guidance instruments for adaptation planning. Total scores among evaluated plans ranged from 16% of the maximum possible score to 61%, with an average of 37%. These results suggest adaptation plans are largely under-developed. Critical weaknesses in adaptation planning are related to limited consideration for non-climatic factors as well as neglect for issues of adaptive capacity including entitlements to various forms of capital needed for effective adaptation. Such gaps in planning suggest there are opportunities for institutions to make better use of existing guidance for adaptation planning and the need to consider the broader governance context in which adaptation will occur. In addition, the adaptation options prescribed by adaptation plans reflect a preferential bias toward low-risk capacity-building (72% of identified options) over the delivery of specific actions to reduce vulnerability. To the extent these findings are representative of the state of developed nation adaptation planning, there appear to be significant deficiencies in climate change preparedness, even among those nations often assumed to have the greatest adaptive capacity.

More than two-thirds of patients in Germany use complementary and alternative medicine (CAM) provided either by physicians or non-medical practitioners (“Heilpraktiker”). There is little information about the number of family physicians (FPs) providing CAM. Given the widespread public interest in the use of CAM, this study aimed to ascertain the use of and attitude toward CAM among FPs in Germany. A postal questionnaire developed based on qualitatively derived data was sent to 3000 randomly selected FPs in Germany. A reminder letter including a postcard (containing a single question about CAM use in practice and reasons for non-particpation in the survey) was sent to all FPs who had not returned the questionnaire. Of the 3000 FPs, 1027 (34%) returned the questionnaire and 444 (15%) returned the postcard. Altogether, 886 of the 1471 responding FPs (60%) reported using CAM in their practice. A positive attitude toward CAM was indicated by 503 FPs (55%), a rather negative attitude by 127 FPs (14%). Chirotherapy, relaxation and neural therapy were rated as most beneficial CAM therapies by FPs, whereas neural therapy, phytotherapy and acupuncture were the most commonly used therapies in German family practices. This survey clearly demonstrates that CAM is highly valued by many FPs and is already making a substantial contribution to first-contact primary care in Germany. Therefore, education and research about CAM should be increased. Furthermore, with the provision of CAM by FPs, the role of non-medical CAM practitioners within the German healthcare system is to be questioned. PMID:19293252

Evidence-based guidelines regarding vaginal birth after cesarean from 3 countries (United States, Canada, and United Kingdom) were reviewed. The similarities in the 3 national guidelines (trial of labor after 1 previous cesarean, informed consent, delivery facility and available resources, epidural analgesia, continuous fetal monitoring, and induction and augmentation of labor) are understandable. Differences in recommendations (uterine rupture risk, success rate, intrauterine pressure catheter, and mechanical cervical ripening) are not explained. The likelihood of recommendations being categorized as level A differed: United States, 27% (3/11); Canada, 32% (6/19); and United Kingdom, 0% (0/17). Only 6 publications were cited by all 3 guidelines.

Objective: To present athletic trainers with recommendations for safe weight loss and weight maintenance practices for athletes and active clients and to provide athletes, clients, coaches, and parents with safe guidelines that will allow athletes and clients to achieve and maintain weight and body composition goals. Background: Unsafe weight management practices can compromise athletic performance and negatively affect health. Athletes and clients often attempt to lose weight by not eating, limiting caloric or specific nutrients from the diet, engaging in pathogenic weight control behaviors, and restricting fluids. These people often respond to pressures of the sport or activity, coaches, peers, or parents by adopting negative body images and unsafe practices to maintain an ideal body composition for the activity. We provide athletic trainers with recommendations for safe weight loss and weight maintenance in sport and exercise. Although safe weight gain is also a concern for athletic trainers and their athletes and clients, that topic is outside the scope of this position statement. Recommendations: Athletic trainers are often the source of nutrition information for athletes and clients; therefore, they must have knowledge of proper nutrition, weight management practices, and methods to change body composition. Body composition assessments should be done in the most scientifically appropriate manner possible. Reasonable and individualized weight and body composition goals should be identified by appropriately trained health care personnel (eg, athletic trainers, registered dietitians, physicians). In keeping with the American Dietetics Association (ADA) preferred nomenclature, this document uses the terms registered dietitian or dietician when referring to a food and nutrition expert who has met the academic and professional requirements specified by the ADA's Commission on Accreditation for Dietetics Education. In some cases, a registered nutritionist may have

Picroside II, an iridoid compound extracted from Picrorhiza, exhibits anti-inflammatory and anti-apoptotic activities. We explored the protective effects and mechanisms of picroside II in a mouse model of sepsis induced by cecal ligation and puncture (CLP), using three groups of mice: Group A (sham), Group B (CLP+NS) and Group C (CLP+20 mg/kg picroside II). The mortality in mice with sepsis was decreased by the administration of picroside II, and lung injury was alleviated simultaneously. Picroside II treatment enhanced bacterial clearance in septic mice. Further, picroside II treatment alleviated the inflammatory response in sepsis and enhanced immune function by inhibiting the activation of NLRP3 inflammasome and NF-κB pathways. Picroside II may represent an anti-inflammatory drug candidate, providing novel insight into the treatment of sepsis. PMID:28078023

Despite advances in recent years, sepsis is still a leading cause of hospitalization and mortality in infants and children. The presence of biomarkers during the response to an infectious insult makes it possible to use such biomarkers in screening, diagnosis, prognosis (risk stratification), monitoring of therapeutic response, and rational use of antibiotics (for example, the determination of adequate treatment length). Studies of biomarkers in sepsis in children are still relatively scarce. This review addresses the use of biomarkers in sepsis in pediatric patients with emphasis on C-reactive protein, procalcitonin, interleukins 6, 8, and 18, human neutrophil gelatinase, and proadrenomedullin. Assessment of these biomarkers may be useful in the management of pediatric sepsis. PMID:28099644

High-density lipoprotein (HDL) is a key component of circulating blood and plays essential roles in regulation of vascular endothelial function and immunity. Clinical data demonstrate that HDL levels drop by 40-70% in septic patients, which is associated with a poor prognosis. Experimental studies using Apolipoprotein A-I (ApoAI) null mice showed that HDL deficient mice are susceptible to septic death, and overexpressing ApoAI in mice to increase HDL levels protects against septic death. These clinical and animal studies support our hypothesis that a decrease in HDL level is a risk factor for sepsis, and raising circulating HDL levels may provide an efficient therapy for sepsis. In this review, we discuss the roles of HDL in sepsis and summarize the efforts of using synthetic HDL as a potential therapy for sepsis.

Since it was proposed in 2007, molecular hydrogen therapy has been widely concerned and researched. Many animal experiments were carried out in a variety of disease fields, such as cerebral infarction, ischemia reperfusion injury, Parkinson syndrome, type 2 diabetes mellitus, metabolic syndrome, chronic kidney disease, radiation injury, chronic hepatitis, rheumatoid arthritis, stress ulcer, acute sports injuries, mitochondrial and inflammatory disease, and acute erythema skin disease and other pathological processes or diseases. Molecular hydrogen therapy is pointed out as there is protective effect for sepsis patients, too. The impact of molecular hydrogen therapy against sepsis is shown from the aspects of basic vital signs, organ functions (brain, lung, liver, kidney, small intestine, etc.), survival rate, and so forth. Molecular hydrogen therapy is able to significantly reduce the release of inflammatory factors and oxidative stress injury. Thereby it can reduce damage of various organ functions from sepsis and improve survival rate. Molecular hydrogen therapy is a prospective method against sepsis.
Tackling sepsis - the potentially fatal over-reaction of the immune system to infection - must be given the same priority as reducing Clostridium difficile and MRSA infections, the government has said.

In the heart, histamine (H3) receptors may function as inhibitory presynaptic receptors that decrease adrenergic norepinephrine release in conditions of enhanced sympathetic neural activity. We hypothesized that H3-receptor blockade might improve cardiovascular function in sepsis. In a canine model of Escherichia coli sepsis, we found that H3-receptor blockade increased cardiac output (3.6 to 5.3 l/min, P < 0.05), systemic blood pressure (mean 76 to 96 mmHg, P < 0.05), and left ventricular contractility compared with pretreatment values. Plasma histamine concentrations increased modestly in the H3-blocker-sepsis group compared with values obtained in a nonsepsis-time-control group. In an in vitro preparation, histamine H3 activation could be identified under conditions of septic plasma. We conclude that activation of H3 receptors may contribute to cardiovascular collapse in sepsis.

Sepsis is an inflammatory response triggered by infection, with a high in-hospital mortality rate. Early recognition and treatment can reverse the inflammatory response, with evidence of improved patient outcomes. One challenge clinicians face is identifying the inflammatory syndrome against the background of the patient's infectious illness and comorbidities. An approach to this problem is implementation of computerized early warning tools for sepsis. This multicenter retrospective study sought to determine clinimetric performance of a cloud-based computerized sepsis clinical decision support system (CDS), understand the epidemiology of sepsis, and identify opportunities for quality improvement. Data encompassed 6200 adult hospitalizations from 2012 through 2013. Of 13% patients screened-in, 51% were already suspected to have an infection when the system activated. This study focused on a patient cohort screened-in before infection was suspected; median time from arrival to CDS activation was 3.5 hours, and system activation to diagnostic collect was another 8.6 hours.

Infections and sepsis are more common in cirrhotic than in the general population and constitute the commonest cause of sudden worsening and death. The diagnosis of systemic inflammatory syndrome and sepsis are challenging in cirrhotics due to an underlying a state of hyperdynamic circulation. Further, poor nutritional and bone marrow reserves lead to modest host immune response, the so called immunoparalysis state and the outcome of antibiotic therapy is suboptimal. In this review, a comprehensive description of current and emerging concepts in the pathogenesis and diagnosis of sepsis with importance to current and novel biomarkers for diagnosis of sepsis in cirrhosis is presented. Furthermore, novel treatment options and preventive strategies are discussed to improve the overall survival.

Every year numerous individuals develop the morbid condition of sepsis. Therefore, novel biomarkers that might better inform clinicians treating such patients are sorely needed. Difficulty in identifying such markers is in part due to the complex heterogeneity of sepsis, resulting from the broad and vague definition of this state/condition based on numerous possible clinical signs and symptoms as well as an incomplete understanding of the underlying pathobiology of this complex condition. This review considers some of the attempts that have been made so far, looking at both the pro- and anti-inflammatory response to sepsis, as well as genomic analysis, as sources of potential biomarkers. Irrespective, for functional biomarker(s) of sepsis to successfully translate from the laboratory to a clinical setting, the biomarker must be target specific and sensitive as well as easy to implement/interpret, and be cost effective, such that they can be utilized routinely in patient diagnosis and treatment.

Kidney transplantation has become more resource intensive as recipient complexity has increased and average donor quality has diminished over time. A national retrospective cohort study was performed to assess the impact of kidney donor and recipient characteristics on transplant center cost (exclusive of organ acquisition) and Medicare reimbursement. Data from the national transplant registry, University HealthSystem Consortium hospital costs, and Medicare payments for deceased donor (N = 53 862) and living donor (N = 36 715) transplants from 2002 to 2013 were linked and analyzed using multivariate linear regression modeling. Deceased donor kidney transplant costs were correlated with recipient (Expected Post Transplant Survival Score, degree of allosensitization, obesity, cause of renal failure), donor (age, cause of death, donation after cardiac death, terminal creatinine), and transplant (histocompatibility matching) characteristics. Living donor costs rose sharply with higher degrees of allosensitization, and were also associated with obesity, cause of renal failure, recipient work status, and 0-ABDR mismatching. Analysis of Medicare payments for a subsample of 24 809 transplants demonstrated minimal correlation with patient and donor characteristics. In conclusion, the complexity in the landscape of kidney transplantation increases center costs, posing financial disincentives that may reduce organ utilization and limit access for higher-risk populations.

Lateral epicondylitis is a common cause of elbow pain, frequently responsive to nonoperative management. There are multiple operative techniques for persistently symptomatic patients who have exhausted conservative therapies. Little is known regarding US national trends in operative management of lateral epicondylitis. We conducted a study to investigate changes in use of ambulatory procedures for lateral epicondylitis. Cases of lateral epicondylitis were identified using the National Survey of Ambulatory Surgery and were analyzed for trends in demographics and use of ambulatory surgery. Between 1994 and 2006, the population-adjusted rate of ambulatory surgical procedures increased from 7.29 to 10.44 per 100,000 capita. The sex-adjusted rate of surgery for lateral epicondylitis increased by 85% among females and decreased by 31% among males. Most patients were between ages 40 and 49 years, and the largest percentage increase in age-adjusted rates was found among patients older than 50 years (275%) between 1994 and 2006. Use of regional anesthesia increased from 17% in 1994 to 30% in 2006. Private insurance remained the most common payer. Awareness of the increasing use of ambulatory surgery for lateral epicondylitis may lead to changes in health care policies and positively affect patient care.

Objective: To determine practice pattern of physiotherapists in the neonatal intensive care units (ICUs) in India with regards to cardiopulmonary and neuromuscular physiotherapy. Materials and Methods: A cross-sectional survey was conducted across India, in which 285 questionnaires were sent via e-mail to physiotherapists working in neonatal intensive care units. Results: A total of 139 completed questionnaires were returned with a response rate of 48.7%, with a majority of responses from Karnataka, Maharashtra and Gujarat. More than 90% of physiotherapists performed chest physiotherapy in neonatal ICUs. Chest physiotherapy assessment predominantly focused on vital parameter assessment (86%) and in treatment predominantly focused on percussion (74.1%), vibration (75.5%), chest manipulation (73.3%), postural drainage (67.6%) and suction (65.4%). In neuromuscular physiotherapy more than 60% of physiotherapists used positioning, and parent education, whereas more than 45% focused on passive range of motion exercise and therapeutic handling. Conclusion: The practice pattern of physiotherapists for neonates in neonatal intensive care units involves both chest physiotherapy as well neuromuscular physiotherapy. Chest physiotherapy assessment focused mainly on vital parameter assessment (heart rate, respiratory rate and partial pressure of oxygen saturation SpO2). Treatment focused on airway clearance techniques including percussion, vibration, postural drainage and airway suction. In neuromuscular physiotherapy most physiotherapists focused on parent education and passive range of motion exercise, therapeutic handling, as well as positioning. PMID:24501488

The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.

Although there has been continuous, intensive research for many years in the field of sepsis treatment, currently available treatment options are limited, and there is still a lack of systems that efficiently remove endotoxins as well as mediators. Here, we discuss a newly developed, integrated technique that combines different aspects for their use in extracorporeal blood purification for the supportive treatment of liver failure and sepsis.

The development of new sepsis-specific biomarkers is mandatory to improve the detection and monitoring of the disease. Hemoglobin is the main oxygen and carbon dioxide carrier in cells of the erythroid lineage and is responsible for oxygen delivery to the respiring tissues of the body. Hemoglobin subunit beta (HBβ) is a component of a larger protein called hemoglobin. The aim of this study was to evaluate blood levels of HBβ in septic patients. A prospective study of 82 patients with sepsis was conducted. Furthermore, C57BL/6 mice were subjected to cecal ligation and puncture (CLP) surgery. Alternatively, human umbilical vein endothelial cells (HUVECs) or C57BL/6 mice were exposed to lipopolysaccharide (LPS, 100 ng/ml to HUVECs or 10 mg/kg to mice). The data showed that LPS induced upregulation of the synthesis and secretion of HBβ in LPS-treated HUVECs and in LPS-injected and CLP mice. In patients admitted to the intensive care unit with sepsis, circulating levels of HBβ were significantly high (sepsis, 64.93-114.76 ng/ml, n = 30; severe sepsis, 157.37-268.69 ng/ml, n = 22; septic shock, 309.98-427.03 ng/ml, n = 30) when compared to the levels of control donors (9.76-12.28 ng/ml, n = 21). Patients with septic shock had higher HBβ levels when compared to patients with severe sepsis. Furthermore, the HBβ levels in septic patients were higher than those in healthy volunteers. These results suggest that in septic patients, HBβ blood level is related to the severity of sepsis and may represent a novel endothelial cell dysfunction marker. Moreover, HBβ can be used as a biomarker to determine the severity of sepsis.

Wild bitter gourd (Momordica charantia L. var. abbreviate Seringe), a common vegetable in Asia, is used in traditional medicine to treat various diseases, including inflammation. Extant literature indicates that wild bitter gourds have components that activate PPARα and PPARγ. This research probed the influence of adding wild bitter gourd to diets on inflammation responses in mice with sepsis induced by intraperitoneal injection of LPS. Male BALB/c mice were divided normal, sepsis, positive control, and three experimental groups. The latter ate diets with low (1%), moderate (2%), and high (10%) ratios of wild bitter gourd lyophilized powder. Before mice were sacrificed, with the exception of the normal group, intraperitoneal injection of LPS induced sepsis in each group; positive control group was injected with LPS after PDTC. This experiment revealed starkly lower weights in groups with added wild bitter gourd than those of the remaining groups. Blood lipids (TG, cholesterol, and NEFA) were also lower in comparison to the sepsis group, and blood glucose concentrations recovered and approached normal levels. Blood biochemistry values related to inflammation reactions indicated GOT, GPT, C-RP, and NO concentrations of groups with added wild bitter gourd were all lower than those of the sepsis group. Secretion levels of the spleen pro-inflammatory cytokines IL-1, IL-6, and TNF-α tallied significantly lower in comparison to the sepsis group, whereas secretion levels of IL-10 anti-inflammatory cytokine increased. Expression level of proteins NF-κB, iNOS, and COX-2 were significantly inhibited. Results indicate wild bitter gourd in diets promoted lipid metabolism, reducing fat accumulation, and improving low blood glucose in sepsis. Addition of wild bitter gourd can reduce inflammation biochemical markers or indicators and pro-inflammatory cytokines in the body, hence improving the inflammation responses in mice with sepsis.

Abstract Determine what clinical role, if any, GM-CSF may have in the clinical treatment of sepsis in the adult patient. Advancements in the management of sepsis have led to significant decreases in early mortality; however, sepsis remains a significant source of long-term mortality and disability which places strain on healthcare resources with a substantial growing economic impact. Historically, early multiple organ failure (MOF) and death in patients with severe sepsis was thought to result from an exaggerated proinflammatory response called the systemic inflammatory response syndrome (SIRS). Numerous prospective randomized controlled trials (PRCTs) tested therapies aimed at decreasing the organ injury associated with an exaggerated inflammatory response. With few exceptions, the results from these PRCTs have been disappointing, and currently no specific therapeutic agent is approved to counteract the early SIRS response in patients with severe sepsis. It has long been recognized that there is a delayed immunosuppressive state that contributes to long-term morbidity. However, recent findings now support a concurrent proinflammatory and anti-inflammatory response present throughout sepsis. Multiple immunomodulating agents have been studied to combat the immunosuppressive phase of sepsis with the goal of decreasing secondary infection, reducing organ dysfunction, decreasing ICU stays, and improving survival. Granulocyte-macrophage colony stimulating factor (GM-CSF), a myelopoietic growth factor currently used in patients with neutropenia secondary to chemotherapy-induced myelosuppression, has been studied as a potential immune-activating agent. The applicability of GM-CSF as a standard therapy for generalized sepsis is still largely understudied; however, small-scale studies available have demonstrated some improved recovery from infection, decreased hospital length of stay, decreased days requiring mechanical ventilation, and decreased medical costs.

This study examined the role of exogenous heat shock protein 72 (Hsp72) in reversing sepsis-induced liver dysfunction. Sepsis was induced by cecal ligation and puncture. Liver function was determined on the basis of the enzymatic activities of serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT). Apoptosis was determined using terminal deoxynucleotidyl transferase dUTP nick end labeling staining. B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), cleaved caspase-3 and caspase-9, and cleaved poly (ADP-ribose) polymerase (PARP) protein expressions were analyzed using Western blotting. Results showed GOT and GPT levels increased during sepsis, and levels were restored following the administration of human recombinant Hsp72 (rhHsp72). Increased liver tissue apoptosis was observed during sepsis, and normal apoptosis resumed on rhHsp72 administration. The Bcl-2/Bax ratio, cleaved caspase-3, caspase-9, and PARP protein expressions in the liver tissues were upregulated during sepsis and normalized after rhHsp72 treatment. We conclude that, during sepsis, exogenous Hsp72 restored liver dysfunction by inhibiting apoptosis via the mitochondria-initiated caspase pathway.

Background. Despite extensive research and an improved standard of care, sepsis remains a disorder with a high mortality rate. Sepsis is accompanied by severe metabolic alterations. Methods. We evaluated 117 patients with sepsis (severe sepsis [n = 19] and septic shock [n = 98]) who were admitted to the intensive care unit. Serum cholesterol, triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), free fatty acid (FFA), and apolipoprotein (Apo) A-I levels were measured on days 0, 1, 3, and 7. Results. Nonsurvivors had low levels of cholesterol, TG, HDL, LDL, and Apo A-I on days 0, 1, 3, and 7. In a linear mixed model analysis, the variations in TG, LDL, FFA, and Apo A-I levels over time differed significantly between the groups (p = 0.043, p = 0.020, p = 0.005, and p = 0.015, resp.). According to multivariate analysis, TG levels and SOFA scores were associated with mortality on days 0 and 1 (p = 0.018 and p = 0.008, resp.). Conclusions. Our study illustrated that TG levels are associated with mortality in patients with sepsis. This may be attributable to alterations in serum lipid metabolism during sepsis, thus modulating the host response to inflammation in critically ill patients. PMID:26351639

Hyperpermeability of the endothelial barrier and resulting microvascular leakage are a hallmark of sepsis. Our studies describe the mechanism by which serotonin (5-HT) regulates the microvascular permeability during sepsis. The plasma 5-HT levels are significantly elevated in mice made septic by cecal ligation and puncture (CLP). 5-HT-induced permeability of endothelial cells was associated with the phosphorylation of p21 activating kinase (PAK1), PAK1-dependent phosphorylation of vimentin (P-vimentin) filaments, and a strong association between P-vimentin and ve-cadherin. These findings were in good agreement with the findings with the endothelial cells incubated in serum from CLP mice. In vivo, reducing the 5-HT uptake rates with the 5-HT transporter (SERT) inhibitor, paroxetine blocked renal microvascular leakage and the decline in microvascular perfusion. Importantly, mice that lack SERT showed significantly less microvascular dysfunction after CLP. Based on these data, we propose that the increased endothelial 5-HT uptake together with 5-HT signaling disrupts the endothelial barrier function in sepsis. Therefore, regulating intracellular 5-HT levels in endothelial cells represents a novel approach in improving sepsis-associated microvascular dysfunction and leakage. These new findings advance our understanding of the mechanisms underlying cellular responses to intracellular/extracellular 5-HT ratio in sepsis and refine current views of these signaling processes during sepsis.

Sepsis is among the most common causes of death in hospitals. It arises from the host response to infection. Currently, diagnosis relies on nonspecific physiological criteria and culture-based pathogen detection. This results in diagnostic uncertainty, therapeutic delays, the mis- and overuse of antibiotics, and the failure to identify patients who might benefit from immunomodulatory therapies. There is a need for new sepsis biomarkers that can aid in therapeutic decision making and add information about screening, diagnosis, risk stratification, and monitoring of the response to therapy. The host response involves hundreds of mediators and single molecules, many of which have been proposed as biomarkers. It is, however, unlikely that one single biomarker is able to satisfy all the needs and expectations for sepsis research and management. Among biomarkers that are measurable by assays approved for clinical use, procalcitonin (PCT) has shown some usefulness as an infection marker and for antibiotic stewardship. Other possible new approaches consist of molecular strategies to improve pathogen detection and molecular diagnostics and prognostics based on transcriptomic, proteomic, or metabolic profiling. Novel approaches to sepsis promise to transform sepsis from a physiologic syndrome into a group of distinct biochemical disorders and help in the development of better diagnostic tools and effective adjunctive sepsis therapies.

Sepsis is a complex condition with unacceptable mortality. Betulin is a natural extract with multiple bioactivities. This study aims to evaluate the potential effects of betulin on lung and liver injury in sepsis. Cecal ligation and puncture was used to establish the rat model of sepsis. A single dose of 4mg/kg or 8mg/kg betulin was injected intraperitoneally immediately after the model establishment. The survival rate was recorded every 12h for 96h. The organ injury was examined using hematoxylin and eosin staining and serum biochemical test. The levels of proinflammatory cytokines and high mobility group box 1 in the serum were measured using ELISA. Western blotting was used to detect the expression of proteins in NF-κB and MAPK signaling pathways. Betulin treatment significantly improved the survival rate of septic rats, and attenuated lung and liver injury in sepsis, including the reduction of lung wet/dry weight ratio and activities of alanine aminotransferase and aspartate aminotransferase in the serum. In addition, levels of tumor necrosis factor-α, interleukin-1β, interleukin-6 and high mobility group box 1 in the serum were also lowered by betulin treatment. Moreover, sepsis-induced activation of the NF-κB and MAPK signaling pathway was inhibited by betulin as well. Our findings demonstrate the protective effect of betulin in lung and liver injury in sepsis. This protection may be mediated by its anti-inflammatory and NF-κB and MAPK inhibitory effects.

Sepsis represents a major cause of lethality during intensive care unit (ICU) treatment. Pharmacological treatment strategies for sepsis are still limited and mainly based on the early initiation of antibiotic and supportive treatment. In this context, numerous clinical and serum based markers have been evaluated for the diagnosis, the severity, and the etiology of sepsis. However until now, few of these factors could be translated into clinical use. MicroRNAs (miRNAs) do not encode for proteins but regulate gene expression by inhibiting the translation or transcription of their target mRNAs. Recently it was demonstrated that miRNAs are released into the circulation and that the spectrum of circulating miRNAs might be altered during various pathologic conditions, such as inflammation, infection, and sepsis. By using array- and single PCR-based methods, a variety of deregulated miRNAs, including miR-25, miR-133a, miR-146, miR-150, and miR-223, were described in the context of sepsis. Some of the miRNAs correlated with the disease stage, as well as patients’ short and long term prognosis. Here, we summarize the current findings on the role of circulating miRNAs in the diagnosis and staging of sepsis in critically ill patients. We compare data from patients with findings from animal models and, finally, highlight the challenges and drawbacks that currently prevent the use of circulating miRNAs as biomarkers in clinical routine.

Sepsis is a systemic inflammatory response syndrome due to infection. The incidence rate is estimated to be up to 19 million cases worldwide per year and the number of cases is rising. Infection triggers a complex and prolonged host response, in which both the innate and adaptive immune response are involved. The disturbance of immune system cells plays a key role in the induction of abnormal levels of immunoregulatory molecules. Furthermore, the involvement of effector immune system cells also impairs the host response to the infective agents and tissue damage. Recently, postmortem studies of patients who died of sepsis have provided important insights into why septic patients die and showed an extensive depletion of CD4 and CD8 lymphocytes and they found that circulating blood cells showed similar findings. Thus, the knowledge of the characterization of circulating lymphocyte abnormalities is relevant for the understanding of the sepsis pathophysiology. In addition, monitoring the immune response in sepsis, including circulating lymphocyte subsets count, appears to be potential biomarker for predicting the clinical outcome of the patient. This paper analyzes the lymphocyte involvement and dysfunction found in patients with sepsis and new opportunities to prevent sepsis and guide therapeutic intervention have been revealed.

Sepsis refers to severe systemic inflammation in response to invading pathogens. An overwhelming immune response, as mediated by the release of various inflammatory mediators, can lead to shock, multiple organ damage, and even death. Cytokines, proteases, lipid mediators, gaseous substances, vasoactive peptides, and cell stress markers play key roles in sepsis pathophysiology. Various adhesion molecules and chemokines sequester and activate neutrophils into the target organs, further augmenting inflammation and tissue damage. Although the anti-inflammatory substances counterbalance proinflammatory mediators, prolonged immune modulation may cause host susceptibility to concurrent infections, thus reflecting enormous challenge toward developing effective clinical therapy against sepsis. To understand the complex interplay between pro- and anti-inflammatory phenomenon in sepsis, there is still an unmet need to study newly characterized mediators. In addition, revealing the current trends of novel mediators will upgrade our understanding on their signal transduction, cross-talk, and synergistic and immunomodulating roles during sepsis. This review highlights the latest discoveries of the mediators in sepsis linking to innate and adaptive immune systems, which may lead to resolution of many unexplored queries. PMID:23136259

Patients surviving sepsis develop anemia but the molecular mechanism is unknown. Here we observed that mice surviving polymicrobial Gram-negative sepsis develop hypochromic, microcytic anemia with reticulocytosis. The bone marrow of sepsis survivors accumulates polychromatophilic and orthochromatic erythroblasts. Compensatory extramedullary erythropoiesis in the spleen is defective during terminal differentiation. Circulating TNF and IL-6 are elevated for five days after the onset of sepsis, and serum HMGB1 levels are increased from day seven until at least day 28. Administration of recombinant HMGB1 to healthy mice mediates anemia with extramedullary erythropoiesis and significantly elevated reticulocyte counts. Moreover, administration of anti-HMGB1 monoclonal antibodies after sepsis significantly ameliorates the development of anemia (hematocrit 48.5±9.0% versus 37.4±6.1%, p<0.01, hemoglobin 14.0±1.7g/dL versus 11.7±1.2g/dL, p<0.01). Together, these results indicate that HMGB1 mediates anemia by interfering with erythropoiesis, suggesting a potential therapeutic strategy for anemia in sepsis.

These new findings advance our understanding of the mechanisms underlying cellular responses to intracellular/extracellular 5-HT ratio in sepsis and refine current views of these signaling processes during sepsis.

Nursing is an applied science. While there is a wide range of nursing theories and nursing care models, resolving the health problems and meeting the health needs of clients is the common objective of all in the nursing profession. The nursing profession may be subdivided into hospital clinical nursing and community health nursing (CHN). CHN is further subdivided into public health nursing, school health nursing, and industrial health nursing. The past 60 years has been a period of significant growth and improvement in Taiwan that has enhanced the nation's socioeconomic condition, general living standards, and general public health. The nursing profession has seen profound progress as well, not only in terms of content but also in terms of nursing care models, which are increasingly framed around core public health needs and take into consideration different health perspectives. Nursing in Taiwan has gradually established its own professional function and autonomy.

This study assessed campsite conditions and the effectiveness of campsite impact management strategies at Isle Royale National Park, USA. Protocols for assessing indicators of vegetation and soil conditions were developed and applied to 156 campsites and 88 shelters within 36 backcountry campgrounds. The average site was 68 m2 and 83% of sites lost vegetation over areas less than 47 m2. Results reveal that management actions to spatially concentrate camping activities and reduce camping disturbance have been highly successful. Comparisons of disturbed area/overnight stay among other protected areas reinforces this assertion. These reductions in area of camping disturbance are attributed to a designated site camping policy, limitation on site numbers, construction of sites in sloping terrain, use of facilities, and an ongoing program of campsite maintenance. Such actions are most appropriate in higher use backcountry and wilderness settings.

The need for efficient management of industrial chemical wastes, especially those considered hazardous or radioactive, is receiving increased attention in the United States. During the past five years, several federal laws have addressed the establishment of stronger programs for the control of hazardous and residual wastes. At a facility such as Oak Ridge National Laboratory (ORNL), an efficient waste management program is an absolute necessity to ensure protection of human health and compliance with regulatory requirements addressing the treatment and disposal of hazardous, nonhazardous, and radioactive wastes. This report highlights the major regulatory requirements under which the Laboratory must operate and their impact on ORNL facilities. Individual waste streams, estimates of quantities of waste, and current waste management operations are discussed.

In this article, I trace the historical and sociopolitical construction of plastic surgery as a basic health need in Brazil. I argue that plastic surgeons deploy "plastic governmentality" in order to portray their work in public settings as humanitarian in nature, while simultaneously using poor patients as experimental subjects to train new surgeons and develop new techniques. This seemingly contradictory positioning is only possible because aesthetic surgeries are relabeled as reconstructive surgeries, producing a pliable form of statecraft that uses statistics and medical discourse to reinforce the support of the state and civil society for the practice. The form of governance I describe elucidates how the state can become instrumentalized in the benefit of private interests under neoliberalism, and how unprofitable public health needs are rendered invisible by the very biopolitical forms of governance that claim to address those needs.

The aim of this study was to provide baseline data on chronic disease management (CDM) provision in Irish general practice (GP). The survey instrument was previously used in a study of primary care physicians in 11 countries, thus allowing international comparisons. The response rate was 72% (380/527).The majority of GPs (240/380; 63%) reported significant changes are needed in our health care system to make CDM work better. Small numbers of routine clinical audits are being performed (95/380; 25%). Irish GPs use evidence based guidelines for treatment of diabetes (267/380; 71%), asthma / COPD (279/380; 74%) and hypertension (297/380; 79%), to the same extent as international counterparts. Barriers to delivering chronic care include increased workload (379/380; 99%), lack of appropriate funding (286/380; 76%), with GPs interested in targeted payments (244/380; 68%). This study provides baseline data to assess future changes in CDM.

Ovarian reserve markers have been documented to perform very well in the clinical practice. While this is widely recognized, still now there is no consensus on how to use new biomarkers in the clinical practice. This study was conducted among Italian IVF centres using the Delphi technique, a validated consensus-building process. Briefly three consecutive questionnaires were developed for clinicians in charge of IVF centres. In the first rounds, participants were asked to rate the importance of a list of statements regarding the categorization of ovarian response and the diagnostic role of biomarkers. In round 3, participants were asked to rate their agreement and consensus on the list of statements derived from the first two rounds. There were 120 respondents. Consensus was achieved for many points: (a) poor ovarian response is predicted on the basis of the following: AMH < 1 ng/ml or AFC < 7, FSH ≥ 10 IU/l, age ≥ 40 yrs; (b) hyper-response is predicted on the basis of the following: AMH > 3 ng/ml or AFC > 14; (c) day 3 FSH measurement should always be associated to estradiol; (d) AMH can be measured on a random basis; (e) the measurement of the AFC with the 2D technology may be considered adequate and (f) the AFC should be measured in the early follicular phase and consists in the total number of 2-9 mm follicles in both the ovaries. The present study suggests that extensive consensus on the importance and use of new ovarian reserve markers to improve IVF safety and performance is already present among clinicians.

Introduction: Resident aesthetic clinics (RACs) have demonstrated good outcomes and acceptable patient satisfaction, but few studies have evaluated their educational, financial, or medicolegal components. We sought to determine RAC best practices. Methods: We surveyed American Council of Academic Plastic Surgeon members (n = 399), focusing on operational details, resident supervision, patient safety, medicolegal history, financial viability, and research opportunities. Of the 96 respondents, 63 reported having a RAC, and 56% of plastic surgery residency program directors responded. Results: RACs averaged 243 patient encounters and 53.9 procedures annually, having been in existence for 19.6 years (mean). Full-time faculty (73%) supervised chief residents (84%) in all aspects of care (65%). Of the 63 RACs, 45 were accredited, 40 had licensed procedural suites, 28 had inclusion/exclusion criteria, and 31 used anesthesiologists. Seventeen had overnight capability, and 17 had a Life Safety Plan. No cases of malignant hyperthermia occurred, but 1 facility death was reported. Sixteen RACs had been involved in a lawsuit, and 33 respondents reported financial viability of the RACs. Net revenue was transferred to both the residents’ educational fund (41%) and divisional/departmental overhead (37%). Quality measures included case logs (78%), morbidity/mortality conference (62%), resident surveys (52%), and patient satisfaction scores (46%). Of 63 respondents, 14 have presented or published RAC-specific research; 80 of 96 of those who were surveyed believed RACs enhanced education. Conclusions: RACs are an important component of plastic surgery education. Most clinics are financially viable but carry high malpractice risk and consume significant resources. Best practices, to maximize patient safety and optimize resident education, include use of accredited procedural rooms and direct faculty supervision of all components of care. PMID:26146599

Purpose: The aim of this study is to explore and compare the prevailing practice patterns in the diagnosis and management of glaucoma among subspecialists and general ophthalmologists in India. Materials and Methods: This is an interactive audience response system (ARS) based poll of ophthalmologists attending the annual conference of the Glaucoma Society of India in 2013. Results: The information was obtained from 379 ophthalmologists (146 glaucoma specialists, 54 nonglaucoma subspecialists, and 179 general ophthalmologists). The majority of polled ophthalmologists (236; 62%) had 10 or more years of experience in ophthalmology. The glaucoma specialists differed from nonglaucomatologists in their preference for Goldmann applanation tonometer (P < 0.01), four-mirror gonioscope (P < 0.01), Humphrey perimeter (P < 0.01), laser peripheral iridotomy in primary angle closure disease (P = 0.03), postiridotomy gonioscopy (P < 0.01), and usage of antifibrotic agents during filtering surgery (P < 0.01). Optical coherence tomography was the most preferred imaging modality and was utilized more often by the subspecialists than general ophthalmologists. The ophthalmologists also differed in their choice of antiglaucoma medications. More glaucoma specialists were performing surgery on children with congenital glaucoma (P < 0.01), implanting glaucoma drainage devices (P < 0.01), and using scientific journals to upgrade knowledge (P = 0.03) than the other ophthalmologists. Conclusions: This poll is the first of its kind in India, in its usage of the ARS, and in comparing the practice patterns of care for glaucoma among subspecialists and general ophthalmologists. It has revealed substantial diversity in a few areas among those who did and did not receive specialty training in glaucoma. PMID:27905331
Background National guidelines on MRSA (methicillin-resistant Staphylococcus aureus) screening policy in England have changed on a number of occasions, but there is limited data on its influence at a local level. The aim of this study was to determine if changes in National policy influenced preoperative screening of cataract patients for MRSA. Methods A structured telephone survey was conducted on all 133 ophthalmology units in England in 2004 and again in 2007 for the initial responders, after a change in national policy. Results A total of 74 units (56%) responded in 2004 and 71 units (96% of initial respondents) in 2007. In 2004, 57% of units screened for MRSA. They screened groups at high risk of carriage, including patients with previous MRSA (93%) and patients from Nursing homes (21%). Swab sites included the nose (100%), eyes (31%) and perineum (62%). In 2007, there was no significant change in the number of units that screened for MRSA (57% vs 66%; p = 0.118; McNemar test). However, more units screened for MRSA in patients from nursing/residential homes (21% vs 51%; p = 0.004, McNemar test), and in patients who had recent admission to hospital (12% vs 36%; p = 0.003). In the second survey, 3 units (6%) now screened patients who were close relatives of MRSA carriers. Conclusion This survey has highlighted inconsistences in MRSA screening practice of day-case cataract surgery patients across England after 2 major national policy changes. A change in DoH policy only led to more units screening patients for MRSA from high risk groups. PMID:24341357

Objective To examine whether preterm very low birth weight (VLBW) infants have an increased risk of late-onset sepsis (LOS) following early-onset sepsis (EOS). Study design Retrospective analysis of VLBW infants (401-1500 g) born September 1998 through December 2009 who survived >72 hours and were cared for within the NICHD Neonatal Research Network. Sepsis was defined by growth of bacteria or fungi in a blood culture obtained ≤72 hr of birth (EOS) or >72 hr (LOS) and antimicrobial therapy for ≥5 days or death <5 d while receiving therapy. Regression models were used to assess risk of death or LOS by 120d and LOS by 120d among survivors to discharge or 120d, adjusting for gestational age and other covariates. Results Of 34,396 infants studied 504 (1.5%) had EOS. After adjustment, risk of death or LOS by 120d did not differ overall for infants with EOS compared with those without EOS [RR:0.99 (0.89-1.09)] but was reduced in infants born at <25wk gestation [RR:0.87 (0.76-0.99), p=0.048]. Among survivors, no difference in LOS risk was found overall for infants with versus without EOS [RR:0.88 (0.75-1.02)], but LOS risk was shorter in infants with BW 401-750 g who had EOS [RR:0.80 (0.64-0.99), p=0.047]. Conclusions Risk of LOS after EOS was not increased in VLBW infants. Surprisingly, risk of LOS following EOS appeared to be reduced in the smallest, most premature infants, underscoring the need for age-specific analyses of immune function. PMID:23295144

Summary Background Unnecessary antibiotic prescribing contributes to antimicrobial resistance. In this trial, we aimed to reduce unnecessary prescriptions of antibiotics by general practitioners (GPs) in England. Methods In this randomised, 2 × 2 factorial trial, publicly available databases were used to identify GP practices whose prescribing rate for antibiotics was in the top 20% for their National Health Service (NHS) Local Area Team. Eligible practices were randomly assigned (1:1) into two groups by computer-generated allocation sequence, stratified by NHS Local Area Team. Participants, but not investigators, were blinded to group assignment. On Sept 29, 2014, every GP in the feedback intervention group was sent a letter from England's Chief Medical Officer and a leaflet on antibiotics for use with patients. The letter stated that the practice was prescribing antibiotics at a higher rate than 80% of practices in its NHS Local Area Team. GPs in the control group received no communication. The sample was re-randomised into two groups, and in December, 2014, GP practices were either sent patient-focused information that promoted reduced use of antibiotics or received no communication. The primary outcome measure was the rate of antibiotic items dispensed per 1000 weighted population, controlling for past prescribing. Analysis was by intention to treat. This trial is registered with the ISRCTN registry, number ISRCTN32349954, and has been completed. Findings Between Sept 8 and Sept 26, 2014, we recruited and assigned 1581 GP practices to feedback intervention (n=791) or control (n=790) groups. Letters were sent to 3227 GPs in the intervention group. Between October, 2014, and March, 2015, the rate of antibiotic items dispensed per 1000 population was 126·98 (95% CI 125·68–128·27) in the feedback intervention group and 131·25 (130·33–132·16) in the control group, a difference of 4·27 (3·3%; incidence rate ratio [IRR] 0·967 [95% CI 0·957–0·977

Tobacco use remains the leading cause of preventable death. The outpatient medical clinic represents an important venue for delivering evidence-based interventions to large numbers of tobacco users. Extensive evidence supports the effectiveness of brief interventions. In a retrospective database analysis of 11,827 adult patients captured in the 2005 National Ambulatory Medical Care Survey (of which 2,420 were tobacco users), we examined the degree to which a variety of patient demographic, clinical and physician-related variables predict the delivery of tobacco counseling during a routine outpatient visit in primary care settings. In 2005, 21.7% of identified tobacco users received a tobacco intervention during their visit. The probability of receiving an intervention differed by gender, geographic region and source of payment. Individuals presenting with tobacco-related health conditions were more likely to receive an intervention. Most physicians classified as specialists were less likely to intervene. The provision of tobacco intervention services appears to be increasing at a modest rate, but remains well below desirable levels. It is a priority that brief interventions be routinely implemented to reduce the societal burden of tobacco use.
The stem cell domain of the regenerative medicine field has seen fundamental changes initiated by seminal discoveries in cell biology, genetic engineering, and whole genome sequencing. Many of these discoveries were funded in part by the National Institutes of Health (NIH), and the NIH remains a leader in supporting research in the United States. However, as the field has developed, the NIH has responded proactively to identify roadblocks and to develop solutions that will accelerate translation of basic discoveries to the clinical setting. These activities range from organizing specialized workshops and coordinating activities among international organizations and the different arms of the government to funding small-scale industry. In addition, the NIH has been a key driver in providing needed infrastructure in areas in which the private sector has been unable to, or does not believe it can, invest. These activities of the NIH are as important as its traditional funding role, and I believe they have contributed to the innovation and rapid pace of discovery in this field.

Background Metal fabrication workers experience high rates of traumatic occupational injuries. Machine operators in particular face high risks, often stemming from the absence or improper use of machine safeguarding or the failure to implement lockout procedures. Methods The National Machine Guarding Program (NMGP) was a translational research initiative implemented in conjunction with two workers' compensation insures. Insurance safety consultants trained in machine guarding used standardized checklists to conduct a baseline inspection of machine‐related hazards in 221 business. Results Safeguards at the point of operation were missing or inadequate on 33% of machines. Safeguards for other mechanical hazards were missing on 28% of machines. Older machines were both widely used and less likely than newer machines to be properly guarded. Lockout/tagout procedures were posted at only 9% of machine workstations. Conclusions The NMGP demonstrates a need for improvement in many aspects of machine safety and lockout in small metal fabrication businesses. Am. J. Ind. Med. 58:1174–1183, 2015. © 2015 The Authors.

Background Improving maternal health is one of the Millennium Development Goals for 2015. Recently some progress has been achieved in reducing mortality. On the other hand, in developed regions, maternal death is a relatively rare event compared to the number of cases of morbidity; hence studying maternal morbidity has become more relevant. Electronic surveillance systems may improve research by facilitating complete data reporting and reducing the time required for data collection and analysis. Therefore the purpose of this study was to describe the methods used in elaborating and implementing the National Network for the Surveillance of Severe Maternal Morbidity in Brazil. Methods The project consisted of a multicenter, cross-sectional study for the surveillance of severe maternal morbidity including near-miss, in Brazil. Results Following the development of a conceptual framework, centers were selected for inclusion in the network, consensus meetings were held among the centers, an electronic data collection system was identified, specific software and hardware tools were developed, research material was prepared, and the implementation process was initiated and analyzed. Conclusion The conceptual framework developed for this network was based on the experience acquired in various studies carried out in the area over recent years and encompasses maternal and perinatal health. It is innovative especially in the context of a developing country. The implementation of the project represents the first step towards this planned management. The system online elaborated for this surveillance network may be used in further studies in reproductive and perinatal health. PMID:21549009

State agencies in the US began covertly testing newborn infants for antibodies to HIV in 1986. In so doing, the HIV serostatus of childbearing mothers is being assessed without directly sampling maternal blood, for neonatal infants harbor maternal antibodies. Approved by the Centers for Disease Control (CDC) and funded by the federal government, serosurveillance programs test virtually all live newborns in the US for antibodies to HIV. Neither is consent for testing sought or obtained from mothers, nor are results on infant serostatus ultimately provided to subjects. The authors oppose ongoing national serosurveillance for HIV on medical, economic, legal, and moral grounds; studies have after all already described the epidemiology of HIV diseases. This ongoing research project has no direct benefit to those tested and treats human subjects like simple laboratory animals. The paper calls attention to the program's inherent sexism, racism, eugenics, invasion of privacy, and science without control. Medical principles; issues of concern; neonatal HIV serosurveillance; ethical issues; legal issues; an overview of HIV testing guidelines; and testing justifications of the World Health Organization, the CDC, and state health agencies are considered in separate sections. The World Medical Association, American Medical Association, epidemiological ethics, and other ethical guidelines are raised in the discussion on ethics, while common law, constitutions, federal statues, the Nuremburg Code, and international laws are reviewed under the rubric of legal concerns.

Background. Improving mentorship may help decrease the shortage of young investigators (graduate students, postdoctoral fellows, and new investigators) available to work as independent researchers in cardiovascular and respiratory health. Objectives. To determine (1) the mentoring practices for trainees affiliated with the Canadian Institutes of Health Research (CIHR), Institute of Circulatory and Respiratory Health (ICRH), (2) the positive attributes of mentors, and (3) the recommendations regarding what makes good mentorship. Methods. We conducted a survey and descriptive analysis of young investigators with a CIHR Training and Salary Award from 2010 to 2013 or who submitted an abstract to the ICRH 2014 Young Investigators Forum. Clinicians were compared to nonclinicians. Results. Of 172 participants, 7.0% had no mentor. Only 43.6% had defined goals and 40.7% had defined timelines, while 54.1% had informal forms of mentorship. A significant proportion (33.1%) felt that their current mentorship did not meet their needs. Among clinicians, 22.2% would not have chosen the same mentor again versus 11.4% of nonclinicians. All participants favored mentors who provided guidance on career and work-life balance. Suggestions for improved mentoring included formal mentorship, increased networking, and quality assurance. Conclusion. There is an important need to improve mentoring in cardiovascular and respiratory health. PMID:27445544

Background Treatment of allergic rhinitis (AR) consistent with consensus guidelines is reported to result in better patient outcomes. However, physicians may manage patients independently of guidelines. Asian data on physician perspectives regarding AR diagnosis and management is limited. Objective The study objective is to assess attitudes and practices on AR of Filipino specialists and generalists. Methods A cross sectional survey of 100 specialists and 100 generalists was conducted from November 2014 to January 2015. A previously validated and pilot tested questionnaire was administered via structured face to face interviews. Results Specialists reported greater adequate knowledge of AR (specialists, 58%; generalists, 39%) and adherence to guidelines (specialists, 84%; generalists, 54%). Diagnostic tests were not routinely used (specialists, 81%; generalists, 92%). Monotherapy, specifically antihistamines, was preferred for mild AR. For moderate-severe AR, preference for monotherapy versus combination therapy (specialists, 49% vs. 51%; generalists, 44% vs. 56%) was similar. Both groups preferred intranasal corticosteroid spray (INCS) for monotherapy and antileukotrienes, antihistamines, INCS for combination therapy. For adjuvant therapy, specialists (82%) preferred nasal irrigation/douche. Primary consideration for choice of therapy was efficacy. Cost was the perceived reason for patients' noncompliance with treatment. Conclusion Despite differences in awareness of and adherence to guidelines, prescribing patterns on management of mild and moderate-severe AR are similar among Filipino specialists and generalists. This can be attributed to a shared perception of efficacy and cost as drivers for therapeutic choices. PMID:26539402

In Atkins v. Virginia 2002, the U.S. Supreme Court held that the Eighth Amendment prohibits executing offenders who are mentally retarded. Rather than adopting a uniform definition of mental retardation, the court charged each state with defining mental retardation in a manner that enforces the constitutional restriction. An unanswered question is how states define mental retardation after Atkins, which has implications for capital defendants and forensic evaluators who conduct capital mitigation evaluations. This project identified the statutory definitions of mental retardation in each state, and grouped the definitions based on consistency with accepted clinical criteria for mental retardation. Results show that definitions of mental retardation vary considerably by state. The large majority of states, both overall and specifically among death penalty states, use criteria for mental retardation that are not entirely consistent with accepted clinical standards. As such, it is not clear whether the majority of states are effectuating the intent of Atkins. The implications of these findings for both policy and practice are discussed.

By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

The relationship of forests in water quantity and quality has been debated during the past years. At the same time, focus on climate change has increased interest in ecosystem restoration as a means for adaptation. Climate change might become one of the key drivers pushing integrated approaches for natural resources management into practice. The National Adaptation Programme of Action (NAPA) is an initiative agreed under the UN Framework Convention on Climate Change. An analysis was done to find out how widely ecosystem restoration and integrated approaches have been incorporated into NAPA priority adaptation projects. The data show that that the NAPAs can be seen as potentially important channel for operationalizing various integrated concepts. Key challenge is to implement the NAPA projects. The amount needed to implement the NAPA projects aiming at ecosystem restoration using integrated approaches presents only 0.7% of the money pledged in Copenhagen for climate change adaptation.

Hispanic people are less likely to seek cancer information and experience more health care barriers than non-Hispanic people. The purpose of this work was to identify cancer information-seeking practices among U. S. Hispanic adults and identify demographic characteristics associated with information selected. Data from 622 Hispanic participants in the Health Information National Trends Survey 2007 were analyzed. Results of this study indicated that the leading sources of cancer information came from the Internet (47%, n = 105), followed by health care providers (26%, n = 60). As educational level increased, Internet use for cancer information-seeking increased from 20.7% (n = 6) to 60.6% (n = 40). These data indicate a necessity to improve information delivery strategies tailored to this group.

We present a practical guide for the implementation of recently revised National Institute on Aging-Alzheimer's Association guidelines for the neuropathologic assessment of Alzheimer's disease (AD). Major revisions from previous consensus criteria are: (1) recognition that AD neuropathologic changes may occur in the apparent absence of cognitive impairment, (2) an "ABC" score for AD neuropathologic change that incorporates histopathologic assessments of amyloid β deposits (A), staging of neurofibrillary tangles (B), and scoring of neuritic plaques (C), and (3) more detailed approaches for assessing commonly co-morbid conditions such as Lewy body disease, vascular brain injury, hippocampal sclerosis, and TAR DNA binding protein (TDP)-43 immunoreactive inclusions. Recommendations also are made for the minimum sampling of brain, preferred staining methods with acceptable alternatives, reporting of results, and clinico-pathologic correlations.

The National Renewable Energy Laboratory (NREL) is a U.S. Department of Energy (DOE) research laboratory that employs more than 2,500 people. The laboratory focuses on renewable energy and energy-efficiency research and has two campuses along the Front Range of Colorado. In 2014, NREL worked with Abt Environmental Research (then called Stratus Consulting Inc.) to develop a vulnerability assessment and resiliency action plan as part of NREL's Climate Change Resiliency and Preparedness (CCRP) project. This guide describes the process that NREL undertook during this project. NREL used a participatory approach to vulnerability assessment and resiliency planning that emphasized organizational context, building internal capacity, and the application of climate science in a practical and actionable manner.
