    2010-03-01

    Full Text Available Abstract Background One in four Swedish women suffers a hip fracture yielding high morbidity and mortality. We wanted to revalidate a 4-item clinical risk score and evaluate a portable heel bone mineral density (BMD technique regarding hip and fragility fracture risk among elderly women. Methods In a population-based prospective cohort study we used clinical risk factors from a baseline questionnaire and heel BMD to predict a two-year hip and fragility fracture outcome for women, in a fracture preventive program. Calcaneal heel BMD was measured by portable dual X-ray laser absorptiometry (DXL and compared to hip BMD, measured with stationary dual X-ray absorptiometry (DXA technique. Results Seven women suffered hip fracture and 14 women fragility fracture/s (at hip, radius, humerus and pelvis among 285 women; 60% having heel BMD ≤ -2.5 SD. The 4-item FRAMO (Fracture and Mortality Index combined the clinical risk factors age ≥80 years, weight Conclusions In a follow-up study we identified high risk groups for hip and fragility fracture with our plain 4-item risk model. Increased fracture risk was also related to decreasing heel BMD in calcaneal bone, measured with a mobile DXL technique. A combination of high FRAMO Index, prior fragility fracture, and very low BMD restricted the high risk group to 11%, among whom most hip fractures occurred (71%. These practical screening methods could eventually reduce hip fracture incidence by concentrating preventive resources to high fracture risk women.

  5. Risk Management in the Clinical Laboratory

    Njoroge, Sarah W

    2014-01-01

    Clinical laboratory tests play an integral role in medical decision-making and as such must be reliable and accurate. Unfortunately, no laboratory tests or devices are foolproof and errors can occur at pre-analytical, analytical and post-analytical phases of testing. Evaluating possible conditions that could lead to errors and outlining the necessary steps to detect and prevent errors before they cause patient harm is therefore an important part of laboratory testing. This can be achieved through the practice of risk management. EP23-A is a new guideline from the CLSI that introduces risk management principles to the clinical laboratory. This guideline borrows concepts from the manufacturing industry and encourages laboratories to develop risk management plans that address the specific risks inherent to each lab. Once the risks have been identified, the laboratory must implement control processes and continuously monitor and modify them to make certain that risk is maintained at a clinically acceptable level. This review summarizes the principles of risk management in the clinical laboratory and describes various quality control activities employed by the laboratory to achieve the goal of reporting valid, accurate and reliable test results.

    Full Text Available Background: Clinical risk management focuses on improving the quality and safety of health care services by identifying the circumstances and opportunities that put patients at risk of harm and acting to prevent or control those risks. The goal of this study is to identify and assess the failure modes in the ICU of Qazvin′s Social Security Hospital (Razi Hospital through Failure Mode and Effect Analysis (FMEA. Methods: This was a qualitative-quantitative research by Focus Discussion Group (FDG performed in Qazvin Province, Iran during 2011. The study population included all individuals and owners who are familiar with the process in ICU. Sampling method was purposeful and the FDG group members were selected by the researcher. The research instrument was standard worksheet that has been used by several researchers. Data was analyzed by FMEA technique. Results: Forty eight clinical errors and failure modes identified, results showed that the highest risk probability number (RPN was in respiratory care "Ventilator′s alarm malfunction (no alarm" with the score 288, and the lowest was in gastrointestinal "not washing the NG-Tube" with the score 8. Conclusions: Many of the identified errors can be prevented by group members. Clinical risk assessment and management is the key to delivery of effective health care.

  7. Risk communication in the clinical consultation.

    Thomson, Richard; Edwards, Adrian; Grey, Jenny

    2005-01-01

    Modern healthcare and modern societies are facing up to the need for greater engagement of patients in treatment decisions. Shared and informed decision-making is replacing traditional paternalistic approaches to decisions; health policy both reflects and drives these changes. A critical contribution to better informed decisions by patients is the effective communication of risk in the clinical consultation. This is not straightforward, but there is a growing evidence base to improve performance in this area to the benefit of both patients and clinicians. The purpose of this review is to provide an accessible and practical guide to better communication of risk by clinicians.

  8. Potential benefits and risks of clinical xenotransplantation

    Full Text Available David KC Cooper,1 David Ayares21Thomas E Starzl Transplantation Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, USA; 2Revivicor, Blacksburg, VA, USAAbstract: The transplantation of organs and cells from pigs into humans could overcome the critical and continuing problem of the lack of availability of deceased human organs and cells for clinical transplantation. Developments in the genetic engineering of pigs have enabled considerable progress to be made in the experimental laboratory in overcoming the immune barriers to successful xenotransplantation. With regard to pig organ xenotransplantation, antibody- and cell-mediated rejection have largely been overcome, and the current major barrier is the development of coagulation dysregulation. This is believed to be due to a combination of immune activation of the vascular endothelial cells of the graft and molecular incompatibilities between the pig and primate coagulation–anticoagulation systems. Pigs with new genetic modifications specifically directed to this problem are now becoming available. With regard to less complex tissues, such as islets (for the treatment of diabetes, neuronal cells (for the treatment of Parkinson's disease, and corneas, the remaining barriers are less problematic, and graft survival in nonhuman primate models extends for >1 year in all three cases. In planning the initial clinical trials, consideration will be concentrated on the risk–benefit ratio, based to a large extent on the results of preclinical studies in nonhuman primates. If the benefit to the patient is anticipated to be high, eg, insulin-independent control of glycemia, and the potential risks low, eg, minimal risk of transfer of a porcine infectious agent, then a clinical trial would be justified.Keywords: infection, pigs, genetically-engineered, xenotransplantation, islets, xenotransplantation, organs

    Purpose Thoracic ultrasound (TUS) has been proposed as an easy-option replacement for chest X-ray (CXR) in emergency diagnosis of pneumonia, pleural effusion, and pneumothorax. We investigated CXR unforeseen diagnosis, subsequently investigated by TUS, considering its usefulness in clinical risk assessment and management and also assessing the sustainability of telementoring. Patients and methods This observational report includes a period of 6 months with proactive concurrent adjunctive TUS diagnosis telementoring, which was done using freely available smartphone applications for transfer of images and movies. Results Three hundred and seventy emergency TUS scans (excluding trauma patients) were performed and telementored. In 310 cases, no significant chest pathology was detected either by CXR, TUS, or the subsequent work-up; in 24 patients, there was full concordance between TUS and CXR (ten isolated pleural effusion; eleven pleural effusion with lung consolidations; and three lung consolidation without pleural effusion); in ten patients with lung consolidations, abnormalities identified by CXR were not detected by TUS. In 26 patients, only TUS diagnosis criteria of disease were present: in 19 patients, CXR was not diagnostic, ie, substantially negative, but TUS detected these conditions correctly, and these were later confirmed by computed tomography (CT). In seven patients, even if chest disease was identified by CXR, such diagnoses were significantly modified by ultrasound, and CT confirmed that TUS was more appropriate. The overall respective individual performances of CXR and TUS for the diagnosis of a pleural–pulmonary disease in emergency are good, with accuracy >95%. Conclusion About 20% of pneumonia cases were detectable only by CXR and 20% only by TUS and not by CXR; ie, about 40% of patients may have been misdiagnosed if, by chance, only one of the two tools had been used. The concurrent use of TUS and CXR increases the overall sensitivity and

    To investigate the cause analysis of clinical medication nursing risks and propose relevant nursing measures, so as to control and reduce the clinical nursing risks and reach the physical and mental safety of patients and nurses. Clinical nursing risk events with 30 cases in TCM Hospital of Zhengzhou City from June 2010 to April 2012 were underwent statistical analyses. The risk of medication error ranked the first in the direct reasons of nursing risks, accounting for a higher ratio. Moreover, the reasons of nursing risks were also involved in nonstandard operation, disease observation and other relative factors. Nurses must fully understand the relative factors of medication nursing risks, regarding the patients as their own family and always permeating the consciousness of nursing risks into the working process.

  16. Clinical presentation and risk factors of osteoradionecrosis

    Chronopoulos, Aristeidis

    2015-03-26

    Introduction: Osteoradionecrosis (ORN) of the jaws is defined as exposed irradiated bone that fails to heal over a period of 3 months without the evidence of a persisting or recurrent tumor. In the previous decades, numerous factors were associated with the risk of ORN development and severity. Aims: The purposes of this study were to present the data of the patients that were treated for ORN in the Department of Oral and Maxillofacial Surgery in Munich (LMU), to detect factors that contributed to the onset of ORN, to identify risk factors associated with the severity of ORN and finally, to delineate and correlate these factors with the personal, health and treatment characteristics of the patients. Material and Methods: A retrospective study was conducted during the period from January 2003 until December 2012 that included all ORN cases having been treated in the Department of Oral and Maxillofacial Surgery in Munich (LMU). The total sample was categorized in three groups according to stage and several variables were evaluated in an attempt to identify possible correlations between them and the necrosis severity. Results: One hundred and fifty three cases of ORN were documented. Among them, 23 (15.1%) cases were stage I, 31 (20.2%) were stage II and 99 (64.7%) were stage III and all localised in the mandible. There was a predominance of the disease in the posterior region when compared to the anterior region. The majority of cases was addicted to alcohol and tobacco abuse and was suffering from Diabetes Mellitus (DM). All cases were treated with RT and 80.4% of them with concomitant chemotherapy. The initial tumor was predominantly located in the floor of the mouth, the tongue and the pharynx. Approximately two thirds of the cases occured either after dental treatment or due to a local pathological condition. Logistic regression analysis identified Diabetes Mellitus (OR: 4.955, 95% Cl: 1.965-12.495), active smoking (OR: 13.542, 95% Cl: 2.085-87.947), excessive

    Prior to 2010, several ISS crewmembers returned from spaceflight with changes to their vision, ranging from a mild hyperopic shift to frank disc edema. As a result, NASA expanded clinical vision testing to include more comprehensive medical imaging, including Optical Coherence Tomography and 3 Tesla Brain and Orbit MRIs. The Space and Clinical Operations (SCO) Division developed a clinical practice guideline that classified individuals based on their symptoms and diagnoses to facilitate clinical care. For the purposes of clinical surveillance, this classification was applied retrospectively to all crewmembers who had sufficient testing for classification. This classification is also a tool that has been leveraged for researchers to identify potential risk factors. In March 2014, driven in part by a more comprehensive understanding of the imaging data and increased imaging capability on orbit, the SCO Division revised their clinical care guidance to outline in-flight care and increase post-flight follow up. The new clinical guidance does not include a classification scheme

Today, more than 40 so-called pressure ulcer risk assessment scales are available but still there is an ongoing debate about their usefulness. From a measurement point of view pressure ulcer (PU risk assessment scales have serious limitations. Empirical evidence supporting the validity of PU risk assessment scale scores is weak and obtained scores contain varying amounts of measurement error. The concept of pressure ulcer risk is strongly related to the general health status and severity of illness. A clinical impact due do the application of these scales could also not be demonstrated. It is questionable whether completion of standardized pressure ulcer risk scales in clinical practice is really needed.Keywords: Braden pressure ulcer, prevention, risk assessment, nursing assessment, predictive value, clinical effectiveness, review

  20. Suicide During Perinatal Period: Epidemiology, Risk Factors and Clinical Correlates

    Laura Orsolini

    2016-08-01

    Full Text Available Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide and infanticide have been considered relatively rare events during the perinatal period. However, in some mental disorders (i.e. postpartum depression, bipolar disorder, postpartum psychosis, etc. have been reported a higher risk of suicidal ideation, suicide attempt or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk and protective factors and an overview about the main clinical correlates associated with the suicidal behaviour during the pregnancy and postpartum period.

    Full Text Available Coronary Artery Disease (CAD is becoming a major cause of morbidity & mortality burden in the developing world. Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

    Thomas, David M; James, Paul A; Ballinger, Mandy L

    2015-06-01

    The study of human genetics has provided substantial insight into cancer biology. With an increase in sequencing capacity and a reduction in sequencing costs, genomics will probably transform clinical cancer genetics. A heritable basis for many cancers is accepted, but so far less than half the genetic drivers have been identified. Genomics will increasingly be applied to populations irrespective of family history, which will change the framework of phenotype-directed genetic testing. Panel testing and whole genome sequencing will identify novel, polygenic, and de-novo determinants of cancer risk, often with lower penetrance, which will challenge present binary clinical classification systems and management algorithms. In the future, genotype-stratified public screening and prevention programmes could form part of tailored population risk management. The integration of research with clinical practice will result in so-called discovery cohorts that will help identify clinically significant genetic variation.

  4. Establishing a family risk assessment clinic for breast cancer.

    Mulsow, Jurgen

    2012-02-01

    Breast cancer is the most common cancer affecting European women and the leading cause of cancer-related death. A total of 15-20% of women who develop breast cancer have a family history and 5-10% a true genetic predisposition. The identification and screening of women at increased risk may allow early detection of breast cancer and improve prognosis. We established a family risk assessment clinic in May 2005 to assess and counsel women with a family history of breast cancer, to initiate surveillance, and to offer risk-reducing strategies for selected high-risk patients. Patients at medium or high risk of developing breast cancer according to NICE guidelines were accepted. Family history was determined by structured questionnaire and interview. Lifetime risk of developing breast cancer was calculated using Claus and Tyrer-Cuzick scoring. Risk of carrying a breast cancer-related gene mutation was calculated using the Manchester system. One thousand two hundred and forty-three patients have been referred. Ninety-two percent were at medium or high risk of developing breast cancer. Formal assessment of risk has been performed in 368 patients, 73% have a high lifetime risk of developing breast cancer, and 72% a Manchester score >or=16. BRCA1\\/2 mutations have been identified in 14 patients and breast cancer diagnosed in two. Our initial experience of family risk assessment has shown there to be a significant demand for this service. Identification of patients at increased risk of developing breast cancer allows us to provide individuals with accurate risk profiles, and enables patients to make informed choices regarding their follow-up and management.

  5. Clinical Risk Factors for Infective Endocarditis in Staphylococcus aureus Bacteremia

    Chapagain, Bikash; Joshi, Astha; Brennessel, Debra J.

    2017-01-01

    Crucial to the management of staphylococcal bacteremia is an accurate evaluation of associated endocarditis, which has both therapeutic and prognostic implications. Because the clinical presentation of endocarditis can be nonspecific, the judicious use of echocardiography is important in distinguishing patients at high risk of developing endocarditis. In the presence of high-risk clinical features, an early transesophageal echocardiogram is warranted without prior transthoracic echocardiography. The purpose of this study was to investigate the clinical risk factors for staphylococcal infective endocarditis that might warrant earlier transesophageal echocardiography and to describe the incidence of endocarditis in cases of methicillin-resistant and methicillin-sensitive Staphylococcus aureus bacteremia. A retrospective case-control study was conducted by means of chart review of 91 patients consecutively admitted to a community hospital from January 2009 through January 2013. Clinical risk factors of patients with staphylococcal bacteremia were compared with risk factors of patients who had definite diagnoses of infective endocarditis. There were 69 patients with bacteremia alone (76%) and 22 patients with endocarditis (24%), as verified by echocardiography. Univariate analysis showed that diabetes mellitus (P=0.024), the presence of an automatic implantable cardioverter-defibrillator/pacemaker (P=0.006) or a prosthetic heart valve (P=0.003), and recent hospitalization (P=0.048) were significantly associated with developing infective endocarditis in patients with S. aureus bacteremia. The incidence of methicillin-resistant and methicillin-sensitive S. aureus bacteremia was similar in the bacteremia and infective-endocarditis groups (P=0.437). In conclusion, identified high-risk clinical factors in the presence of bacteremia can suggest infective endocarditis. Early evaluation with transesophageal echocardiography might well be warranted.

  6. Cerebrovascular risk factors and clinical classification of strokes.

    Pinto, Antonio; Tuttolomondo, Antonino; Di Raimondo, Domenico; Fernandez, Paola; Licata, Giuseppe

    2004-08-01

    Cerebrovascular risk represents a progressive and evolving concept owing to the particular distribution of risk factors in patients with ischemic stroke and in light of the newest stroke subtype classifications that account for pathophysiological, instrumental, and clinical criteria. Age represents the strongest nonmodifiable risk factor associated with ischemic stroke, while hypertension constitutes the most important modifiable cerebrovascular risk factor, confirmed by a host of epidemiological data and by more recent intervention trials of primary (HOT, Syst-Eur, LIFE) and secondary (PROGRESS) prevention of stroke in hypertensive patients. To be sure, a curious relationship exists between stroke and diabetes. Although the Framingham Study, The Honolulu Heart Program, and a series of Finnish studies reported a linear relationship between improved glucose metabolism and cerebral ischemia, the clinical and prognostic profile of diabetic patients with ischemic stroke remains to be fully understood. Our group, on the basis of TOAST classification--a diagnostic classification of ischemic stroke developed in 1993 that distinguishes five different clinical subtypes of ischemic stroke: large-artery atherosclerosis (LAAS), cardioembolic infarct (CEI), lacunar infarct (LAC), stroke of other determined origin (ODE), and stroke of undetermined origin (UDE), and now extensively used in clinical and scientific context--analysed the prevalence of cerebrovascular risk factors and the distribution of TOAST subtypes in more 300 patients with acute ischemic stroke in two consecutives studies that reported the significant association between diabetes and the lacunar subtype and a better clinical outcome for diabetic patients, most likely related to the higher prevalence of the lacunar subtype. Well-confirmed are the roles of cigarette smoking, atrial fibrillation, and asymptomatic carotid stenosis as cerebrovascular risk factors. Particularly interesting seems to be the function of

  8. Clinical symptoms and risk factors in cerebral microangiopathy patients.

    Sandra Okroglic

    Full Text Available OBJECTIVE: Although the clinical manifestation and risk factors of cerebral microangiopathy (CM remain unclear, the number of diagnoses is increasing. Hence, patterns of association among lesion topography and severity, clinical symptoms and demographic and disease risk factors were investigated retrospectively in a cohort of CM patients. METHODS: Patients treated at the Department of Neurology, University of Bonn for CM (n = 223; 98m, 125f; aged 77.32±9.09 from 2005 to 2010 were retrospectively enrolled. Clinical symptoms, blood chemistry, potential risk factors, demographic data and ratings of vascular pathology in the brain based on the Wahlund scale were analyzed using Pearson's chi square test and one-way ANOVA. RESULTS: Progressive cognitive decline (38.1%, gait apraxia (27.8%, stroke-related symptoms and seizures (24.2%, TIA-symptoms (22% and vertigo (17% were frequent symptoms within the study population. Frontal lobe WMLs/lacunar infarcts led to more frequent presentation of progressive cognitive decline, seizures, gait apraxia, stroke-related symptoms, TIA, vertigo and incontinence. Parietooccipital WMLs/lacunar infarcts were related to higher frequencies of TIA, seizures and incontinence. Basal ganglia WMLs/lacunar infarcts were seen in patients with more complaints of gait apraxia, vertigo and incontinence. Age (p = .012, arterial hypertension (p<.000, obesity (p<.000 and cerebral macroangiopathy (p = .018 were positively related to cerebral lesion load. For increased glucose level, homocysteine, CRP and D-Dimers there was no association. CONCLUSION: This underlines the association of CM with neurological symptoms upon admission in a topographical manner. Seizures and vertigo are symptoms of CM which may have been missed in previous studies. In addition to confirming known risk factors such as aging and arterial hypertension, obesity appears to increase the risk as well. Since the incidence of CM is increasing, future

  9. Risk stratification in non-ST elevation acute coronary syndromes: Risk scores, biomarkers and clinical judgment

    David Corcoran

    2015-09-01

    Clinical guidelines recommend an early invasive strategy in higher risk NSTE-ACS. The Global Registry of Acute Coronary Events (GRACE risk score is a validated risk stratification tool which has incremental prognostic value for risk stratification compared with clinical assessment or troponin testing alone. In emergency medicine, there has been a limited adoption of the GRACE score in some countries (e.g. United Kingdom, in part related to a delay in obtaining timely blood biochemistry results. Age makes an exponential contribution to the GRACE score, and on an individual patient basis, the risk of younger patients with a flow-limiting culprit coronary artery lesion may be underestimated. The future incorporation of novel cardiac biomarkers into this diagnostic pathway may allow for earlier treatment stratification. The cost-effectiveness of the new diagnostic pathways based on high-sensitivity troponin and copeptin must also be established. Finally, diagnostic tests and risk scores may optimize patient care but they cannot replace patient-focused good clinical judgment.

    It is unknown why some infants with perinatal stroke present clinical symptoms late during infancy and will be identified as infants with presumed perinatal stroke. The risk factors and clinical and radiological data of 42 infants with presumed perinatal stroke (69% with periventricular venous infarction and 31% with arterial ischemic stroke) from the Estonian Pediatric Stroke Database were reviewed. Children with presumed perinatal stroke were born at term in 95% of the cases and had had no risk factors during pregnancy in 43% of the cases. Children with periventricular venous infarction were born significantly more often (82%) vaginally (P = .0213) compared to children with arterial stroke (42%); nor did they require resuscitation (P = .0212) or had any neurological symptoms after birth (P = .0249). Periventricular venous infarction is the most common type of lesion among infants with the presumed perinatal stroke. Data suggest that the disease is of prenatal origin.

    Full Text Available Objective  To discuss the relative and independent risk factors in ectopic pregnancy. Methods  The clinical data of 870 patients with ectopic pregnancy, admitted from 2005 to 2012, were retrospectively analyzed, with 800 cases of normal pregnancy serving as control. Monofactorial correlation analysis was used to analyze the related risk factor, and logistic regression analysis was used to analyze the independent risk factor. Results  Pelvic adhesion, previous operation, cesarean section delivery, number of pregnancy, artificial abortion, medical abortion, in vitrofertilization and embryo replacement (IVF-ER, and placement of intrauterine device (IUD are the risk factors of ectopic pregnancy, pelvic adhesion, artificial abortion, operation, number of pregnancies and IUD are the independent risk factors, and pelvic adhesion is the major risk factor. Conclusion  Avoidance of unexpected pregnancy as possible, reduction of the number of artificial abortion, prevention and treatment of genital duct inflammation, and standardization of pelvic operation may reduce the incidence of ectopic pregnancy.

    Full Text Available `INTRODUCTION: Stroke is the third leading cause of death in developed countries after cardiovascular disease and cancer. In India Community Surveys have shown a crude prevalence rate for hemiplegia 200 per 1, 00, 000 population. It accounts for nearly 1.5% of all urban admissions, 4.5 % of all medical and about 20% of neurological cases. AIMS AND OBJECTIVE: Identification of risk factors and evaluation of clinical profile of acute stroke. MATERIAL AND METHOD: INCLUSION CRITERIA: Cases of acute stoke admitted in SGMH hospital were selected for the study. EXCLUSION CRITERIA: Brain injury cases, infective, neoplastic cases producing stroke were excluded. RESULTS: Stroke was more common in male, 58 % patients were male and 42% patients were female. It was more common in 5th and 6th decade. Most common etiology was infarction. Most common risk factor was hypertension followed by smoking. In addition to limb weakness, headache and vomiting were most common presenting symptoms followed by convulsion. These symptoms were more common in hemorrhagic stroke. Right sided hemiplegia was more common than left sided. Middle cerebral artery was involved in majority of cases in atherothrombotic stroke whereas basal ganglion was most common site of bleed in hemorrhagic stroke. Coma and mortality were more in hemorrhagic stroke. CONCLUSION: The risk factors and clinical profile of acute stroke in India are similar to that of Western countries. Common risk factors are hypertension, smoking, diabetes mellitus and hyperlipidemia

    Breast cancer risk assessment can inform the use of screening and prevention modalities. We investigated the performance of the Breast Cancer Surveillance Consortium (BCSC) risk model in combination with a polygenic risk score (PRS) comprised of 83 single nucleotide polymorphisms identified from genome-wide association studies. We conducted a nested case-control study of 486 cases and 495 matched controls within a screening cohort. The PRS was calculated using a Bayesian approach. The contributions of the PRS and variables in the BCSC model to breast cancer risk were tested using conditional logistic regression. Discriminatory accuracy of the models was compared using the area under the receiver operating characteristic curve (AUROC). Increasing quartiles of the PRS were positively associated with breast cancer risk, with OR 2.54 (95 % CI 1.69-3.82) for breast cancer in the highest versus lowest quartile. In a multivariable model, the PRS, family history, and breast density remained strong risk factors. The AUROC of the PRS was 0.60 (95 % CI 0.57-0.64), and an Asian-specific PRS had AUROC 0.64 (95 % CI 0.53-0.74). A combined model including the BCSC risk factors and PRS had better discrimination than the BCSC model (AUROC 0.65 versus 0.62, p = 0.01). The BCSC-PRS model classified 18 % of cases as high-risk (5-year risk ≥3 %), compared with 7 % using the BCSC model. The PRS improved discrimination of the BCSC risk model and classified more cases as high-risk. Further consideration of the PRS's role in decision-making around screening and prevention strategies is merited.

    2015-01-01

    Rheumatoid arthritis (RA) is a chronic autoimmune rheumatic disease that can cause painful swelling in the joint lining, morning stiffness, and joint deformation/destruction. These symptoms decrease both quality of life and life expectancy. However, if RA can be diagnosed in the early stages, it can be controlled with pharmacotherapy. Although many studies have examined the possibility of early assessment and diagnosis, few have considered the relationship between significant risk factors and the early assessment of RA. In this paper, we present a novel framework for early RA assessment that utilizes data preprocessing, risk pattern mining, validation, and analysis. Under our proposed framework, two risk patterns can be discovered. Type I refers to well-known risk patterns that have been identified by existing studies, whereas Type II denotes unknown relationship risk patterns that have rarely or never been reported in the literature. These Type II patterns are very valuable in supporting novel hypotheses in clinical trials of RA, and constitute the main contribution of this work. To ensure the robustness of our experimental evaluation, we use a nationwide clinical database containing information on 1,314 RA-diagnosed patients over a 12-year follow-up period (1997-2008) and 965,279 non-RA patients. Our proposed framework is employed on this large-scale population-based dataset, and is shown to effectively discover rich RA risk patterns. These patterns may assist physicians in patient assessment, and enhance opportunities for early detection of RA. The proposed framework is broadly applicable to the mining of risk patterns for major disease assessments. This enables the identification of early risk patterns that are significantly associated with a target disease.

  19. Risk, diagnostic error, and the clinical science of consciousness

    Andrew Peterson

    2015-01-01

    Full Text Available In recent years, a number of new neuroimaging techniques have detected covert awareness in some patients previously thought to be in a vegetative state/unresponsive wakefulness syndrome. This raises worries for patients, families, and physicians, as it indicates that the existing diagnostic error rate in this patient group is higher than assumed. Recent research on a subset of these techniques, called active paradigms, suggests that false positive and false negative findings may result from applying different statistical methods to patient data. Due to the nature of this research, these errors may be unavoidable, and may draw into question the use of active paradigms in the clinical setting. We argue that false positive and false negative findings carry particular moral risks, which may bear on investigators' decisions to use certain methods when independent means for estimating their clinical utility are absent. We review and critically analyze this methodological problem as it relates to both fMRI and EEG active paradigms. We conclude by drawing attention to three common clinical scenarios where the risk of diagnostic error may be most pronounced in this patient group.

  20. Emerging Comorbidities in Adult Asthma: Risks, Clinical Associations, and Mechanisms.

    2016-01-01

    Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Most studies with asthma have been performed in patients being otherwise healthy. However, in real life, comorbid diseases are very common in adult patients. We review here the emerging comorbid conditions to asthma such as obesity, metabolic syndrome, diabetes mellitus type 2 (DM2), and cardiac and psychiatric diseases. Their role as risk factors for incident asthma and whether they affect clinical asthma are evaluated. Obesity, independently or as a part of metabolic syndrome, DM2, and depression are risk factors for incident asthma. In contrast, the effects of comorbidities on clinical asthma are less well-known and mostly studies are lacking. Cross-sectional studies in obese asthmatics suggest that they may have less well controlled asthma and worse lung function. However, no long-term clinical follow-up studies with these comorbidities and asthma were identified. These emerging comorbidities often occur in the same multimorbid adult patient and may have in common metabolic pathways and inflammatory or other alterations such as early life exposures, systemic inflammation, inflammasome, adipokines, hyperglycemia, hyperinsulinemia, lung mechanics, mitochondrial dysfunction, disturbed nitric oxide metabolism, and leukotrienes.

    AIM To compare a group of patients with consecutive exotropia with patients who had ≤10 prism diopters (PD) esotropia or no deviation postoperatively in terms of probable clinical risk factors for the development of consecutive exotropia. METHODS The study recruited fourteen patients who developed consecutive exodeviation during follow-up period after the correction of esotropia who were categorized as group 1 and thirty-one patients who had still ≤10 PD esotropia or no deviation at the final visit that were considered as group 2. Clinical risk factors leading the development of consecutive deviation were analyzed as the main outcome measures. RESULTS The mean age of patients was 4.57±3.11y in group 1 and 5.10±3.52y in group 2 (P=0.634). There was no significant difference of preoperative near and distant deviations among two groups (P=0.835, 0.928 respectively). The mean amount of medial rectus recession and lateral rectus resection was similar in both groups (P=0.412, 0.648 respectively). Convergence insufficiency and neurological diseases were more frequent in group 1 (P=0.007, 0.045). Accompanying neurological disease was found to be as a significant factor increasing the risk of the development of consecutive exotropia significantly [odds ratios (OR): 5.75 (1.04-31.93)]. CONCLUSION Accompanying neurological disease appears to be a significant clinical risk factor for the development of consecutive exodeviation during postoperative follow-up after the correction of esotropia. However, larger studies are needed in order to interpret the results to the clinical practice and to ascertain other concurrent risk factors. PMID:27366693

    Purpose - The European Union recommendations for patient safety calls for shared clinical risk management (CRM) safety standards able to guide organizations in CRM implementation. The purpose of this paper is to develop a self-evaluation tool to measure healthcare organization performance on CRM and guide improvements over time. Design/methodology/approach - A multi-step approach was implemented including: a systematic literature review; consensus meetings with an expert panel from eight Italian leader organizations to get to an agreement on the first version; field testing to test instrument feasibility and flexibility; Delphi strategy with a second expert panel for content validation and balanced scoring system development. Findings - The self-assessment tool - Clinical Assessment of Risk Management: an INtegrated Approach includes seven areas (governance, communication, knowledge and skills, safe environment, care processes, adverse event management, learning from experience) and 52 standards. Each standard is evaluated according to four performance levels: minimum; monitoring; outcomes; and improvement actions, which resulted in a feasible, flexible and valid instrument to be used throughout different organizations. Practical implications - This tool allows practitioners to assess their CRM activities compared to minimum levels, monitor performance, benchmarking with other institutions and spreading results to different stakeholders. Originality/value - The multi-step approach allowed us to identify core minimum CRM levels in a field where no consensus has been reached. Most standards may be easily adopted in other countries.

  4. Dimethyl fumarate-associated lymphopenia: Risk factors and clinical significance

    Longbrake, Erin E; Naismith, Robert T; Parks, Becky J; Wu, Gregory F; Cross, Anne H

    2015-01-01

    Background Dimethyl fumarate (DMF), a disease-modifying therapy for multiple sclerosis (MS), causes lymphopenia in a fraction of patients. The clinical significance of this is unknown. Several cases of progressive multifocal leukoencephalopathy in lymphopenic fumarate-treated patients have raised concerns about drug safety. Since lymphocytes contribute to MS pathology, lymphopenia may also be a biomarker for response to the drug. Objective The objective of this manuscript is to evaluate risk factors for DMF-induced lymphopenia and drug failure in a real-world population of MS patients. Methods We conducted a retrospective cohort study of 221 patients prescribed DMF at a single academic medical center between March 2013 and February 2015. Results Grade 2–3 lymphopenia developed in 17% of the total cohort and did not resolve during DMF treatment. Older age (>55), lower baseline absolute lymphocyte count and recent natalizumab exposure increased the risk of developing moderate to severe lymphopenia while on DMF. Lymphopenia was not predictive of good clinical response or of breakthrough MS activity on DMF. Conclusions Lymphopenia develops in a significant minority of DMF-treated patients, and if grade 2 or worse, is unlikely to resolve while on the drug. Increased vigilance in lymphocyte monitoring and infection awareness is particularly warranted in older patients and those switching from natalizumab. PMID:26550483

  5. Clinical, Molecular, and Environmental Risk Factors for Hodgkin Lymphoma

    Alison Maggioncalda

    2011-01-01

    Full Text Available Epidemiological studies suggest unique occurrence patterns of Hodgkin lymphoma (HL worldwide. In most Western countries there is a clear bimodal age distribution with an early peak in young adults followed by a second peak in older adults, particularly among males. In the Middle East and Asia, HL is more common in early childhood. There also are marked racial differences in the presentations of HL and HL subtypes, and particular single nucleotide polymorphisms (SNPs have been identified as etiological factors suggesting that gene-gene and gene-environment interactions are involved. Personal health choices such as exercise and smoking may modify an individual's chances of developing HL. Numerous studies highlight the impact that exposure to Epstein-Barr virus and other environmental factors have on HL risk. Understanding the relative importance of each of these findings and their links to HL development and survival will help clinical researchers expand curative therapies and create preventative strategies for HL.

  6. Risk management in clinical practice. Part 9. Dental implants.

    Palmer, R M

    2010-11-27

    Patients have high expectations of dental implants in terms of appearance, function and longevity. It is essential that these expectations are realistically managed and that treatment of the highest standard is provided. This involves very careful evaluation, including clinical and radiographic, and presentation of the pros and cons of treatment alternatives. Provision of a successful implant restoration requires many skills including a surgical procedure to place the implant in the best possible position and prosthodontic techniques to provide an aesthetic restoration in occlusal harmony with the rest of the dentition. Recognition of risk factors and long-term maintenance requirements are equally important. Clinicians involved in these treatments must obtain adequate training and develop skills through treatment of straightforward cases using well established protocols before embarking on more demanding cases.

    2012-01-01

    Aim Several studies suggest an association between experiences of childhood trauma including bullying and the development of psychotic symptoms. The use of communications technology has created a new media for bullying called ‘cyberbullying’. Research has demonstrated associations between traditional bullying and cyberbullying. Negative effects of cyberbullying appear similar in nature and severity to the reported effects of traditional bullying. Our aim was to examine the prevalence and correlates of cyberbullying in those at clinical high risk (CHR) for psychosis. Methods Fifty young people at CHR for psychosis were administered the Childhood Trauma Questionnaire with added questions about cyberbullying. Results Cyberbullying was reported in 38% of the sample. Those who experienced cyberbullying also reported experiencing previous trauma. Conclusion It is possible that cyberbullying may be a problem for those at CHR of psychosis and due to the vulnerable nature of these young people, may have longitudinal implications. PMID:23343259

  8. Corticosteroids in chronic obstructive pulmonary disease. Clinical benefits and risks.

    McEvoy, C E; Niewoehner, D E

    2000-12-01

    The use of systemic and inhaled corticosteroids for COPD has increased appreciably over the past 20 years. Clearer indications for corticosteroid therapy in COPD are beginning to emerge as the results from large clinical trials become available. Systemic corticosteroids are only modestly effective for acute COPD exacerbations, increase the risk for hyperglycemia, and should be given for no more than 2 weeks. The efficacy of long-term systemic corticosteroid therapy has not been adequately evaluated in this patient population. If longer term use of systemic steroids in COPD should be found to be useful, this conclusion would have to be weighed against the risk for serious adverse effects. High doses of inhaled corticosteroids cause a small sustained increase of the FEV1 in patients with mild and moderately severe COPD, but they do not slow the rate of FEV1 decline. Based on analyses of secondary outcome, inhaled corticosteroids may improve the respiratory symptoms and decrease the number and severity of COPD exacerbations in patients with more advanced disease. Low doses of inhaled corticosteroids appear to be safe, but there is growing awareness that higher doses may not be so benign.

  9. Assessing hospitals' clinical risk management: Development of a monitoring instrument

    2010-12-01

    Full Text Available Abstract Background Clinical risk management (CRM plays a crucial role in enabling hospitals to identify, contain, and manage risks related to patient safety. So far, no instruments are available to measure and monitor the level of implementation of CRM. Therefore, our objective was to develop an instrument for assessing CRM in hospitals. Methods The instrument was developed based on a literature review, which identified key elements of CRM. These elements were then discussed with a panel of patient safety experts. A theoretical model was used to describe the level to which CRM elements have been implemented within the organization. Interviews with CRM practitioners and a pilot evaluation were conducted to revise the instrument. The first nationwide application of the instrument (138 participating Swiss hospitals was complemented by in-depth interviews with 25 CRM practitioners in selected hospitals, for validation purposes. Results The monitoring instrument consists of 28 main questions organized in three sections: 1 Implementation and organizational integration of CRM, 2 Strategic objectives and operational implementation of CRM at hospital level, and 3 Overview of CRM in different services. The instrument is available in four languages (English, German, French, and Italian. It allows hospitals to gather comprehensive and systematic data on their CRM practice and to identify areas for further improvement. Conclusions We have developed an instrument for assessing development stages of CRM in hospitals that should be feasible for a continuous monitoring of developments in this important area of patient safety.

    2003-03-01

    In the year 2000, the level of methyldibromo glutaronitrile (MDGN) allergy in dermatology clinics in Europe exceeded the level of allergies to all other preservatives, with a prevalence of 3.5%. In the present study, cases of primary sensitization and elicitation to MDGN due to cosmetic products were collected over an 8-month period at the Department of Dermatology, Gentofte University Hospital. The aim was to identify the products related to hand eczema, assess exposure to MDGN in these products and relate the findings to results from a newly developed updated risk assessment model for contact allergy. Out of 24 patients with a positive patch test to MDGN, 17 patients with hand eczema were identified. In 11 of these patients, cosmetic products used in relation to the onset of the disease were shown to contain MDGN (65%). In 8 of these 11 cases, primary sensitization was probable, 5 due to hand/body lotions and 3 due to lotions and/or liquid hand soap. Chemical analysis of 12 products showed that lotions contained 149-390 ppm of MDGN, liquid hand soap 144-399 ppm, a rinsing cream 293 ppm and shampoos 78-79 ppm. The shampoo exposure was not of certain relevance to the eczema. Applying the newly developed updated risk assessment model showed that the concentrations of MDGN in lotions of 149-390 ppm exceeded the calculated maximum acceptable exposure level for MDGN, which would be expected to lead to sensitization in consumers using such products, as seen in the current study. The present cases and updated exposure-based risk assessment process add to the evidence and need for re-defining safe-use concentrations of MDGN in cosmetic products.

    Traditional CV-risk factors in this CKD population were not associated with clinical outcome. Despite being within clinical reference range, serum phosphate and albumin were independently associated with clinical outcome. This may highlight a potential therapeutic target for risk management to delay or prevent renal end-points in CKD.

    Full Text Available Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002 and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient’s admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40, 46.6% (n = 29, 39.7% (n = 27, 35.3% (n = 24, 14.1% (n = 9, respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

    2009-12-01

    Full Text Available The research goal is to determine risk factors of periodontal disease development, psychophysiological personal types and their interrelations in clinically healthy persons. 47 first-year cadets of St.-Petersburg Military School of radio electronics have been examined. This group of respondents has been chosen by presence of such social stressor as change of place of living (97,9% cadets have arrived in St.-Petersburg from other cities and republics of the Russian Federation and strict disciplinary conditions. The research has revealed a low level of oral hygiene, cases of mild gingivitis in most respondents. The general mental state of group under study is characterized by raised level of personal anxiety and low indices of reactive anxiety. The examined group has demonstrated anxiety, tension, indecision and lowered stress stability. Clinically healthy persons are more liable to develop inflammatory and inflammatory-destructive periodontal diseases. It was possible to determine psychophysiological features correlated with physiological parameters of risk degree of periodontal diseases. It may have a great significance in defining of periodontal disease etiology and pathogenesis

    2010-01-01

    Implant therapy has become a widely recognized treatment alternative for replacing missing teeth. Several long term follow-up studies have shown that the survival rate is high. However, complications may appear and risk indcators associated with early and late failures have been identified. The purpose of the present retrospective clinical study was to describe some clinical features of patients with clinical signs of peri-implantitis and to identify risk indicators of peri-implantitis in a population at a specialist clinic of Periodontology. In total,the material consisted of 377 implants in 111 patients with the diagnosis peri-implantitis. The mean age at the examination was found to be 56.3 years (range 22-83) for females and 64.1 years (range 27-85) for males. The mean number of remaining teeth was found to be 10.5 (S.D. 8.89) and the mean number of implants was 5.85 (S.D. 3.42). For a majority of the subjects, more than 50% of the remaining teeth had a marginal bone loss of more than 1/3 of the root length. Forty-sex percent of the patients visited regularly dental hygienists for supportive treatment. The percentage of implants with peri-implantitis was significantly increased for smokers compared to non-smokers (p = 0.04). In the group of non-smokers, 64% of the implants had the diagnosis peri-implantitis, while the corresponding relative frequency for smokers was 78%. A majority of the individuals had a Plaque index and Bleeding on probing index >50%. The median of the follow-up time after implant placement was 7.4 years and the observation period was not significantly correlated to the degree of bone loss around the implants. Among the subjects with a mean bone loss >6 mm at implants with peri-implantitis, more than 70% had a mean marginal bone loss > 1/3 of the root length of the remaining teeth. A positive and significant correlation was found between the degree of marginal bone loss in remaining teeth and the degree of bone loss around implants with peri

    Ocular candidiasis is a major complication of Candida bloodstream infection (BSI). This study was performed to reveal the clinical characteristics of ocular candidiasis. Of the 220 patients with Candida BSI, 204 cases received ophthalmology consultations between January 2005 and December 2011 at 2 teaching hospitals. Fifty-four (26.5%) cases had findings consistent with the diagnosis of ocular candidiasis. Of these 54 cases, 43 (79.6%) were diagnosed within 7 days after a positive blood culture. Among ocular candidiasis cases, more cases were due to Candida albicans (P =0.034 odds ratio [OR]; 3.68 95% confidence interval [CI] 1.11-12.2) and had higher β-d-glucan values (P = 0.001 OR; 9.99 95% CI 2.60-21.3). We need to consider fundoscopic examination to be performed within the first 7 days of therapy, especially for those patients who have C. albicans BSIs and higher β-d-glucan values. Additionally, follow-up fundoscopic examination should be considered before stopping therapy for high-risk patients.

    Signori, Marcos R; Garcia, Renato

    2010-01-01

    This paper presents a model that aids the Clinical Engineering to deal with Risk Management in the Healthcare Technological Process. The healthcare technological setting is complex and supported by three basics entities: infrastructure (IS), healthcare technology (HT), and human resource (HR). Was used an Enterprise Architecture - MODAF (Ministry of Defence Architecture Framework) - to model this process for risk management. Thus, was created a new model to contribute to the risk management in the HT process, through the Clinical Engineering viewpoint. This architecture model can support and improve the decision making process of the Clinical Engineering to the Risk Management in the Healthcare Technological process.

    Carr, Brendan M.; Romeiser, Jamie; Ruan, Joyce; Gupta, Sandeep; Seifert, Frank C.; Zhu, Wei

    2015-01-01

    Abstract Background/aim Clinical risk models are commonly used to predict short‐term coronary artery bypass grafting (CABG) mortality but are less commonly used to predict long‐term mortality. The added value of long‐term mortality clinical risk models over traditional actuarial models has not been evaluated. To address this, the predictive performance of a long‐term clinical risk model was compared with that of an actuarial model to identify the clinical variable(s) most responsible for any differences observed. Methods Long‐term mortality for 1028 CABG patients was estimated using the Hannan New York State clinical risk model and an actuarial model (based on age, gender, and race/ethnicity). Vital status was assessed using the Social Security Death Index. Observed/expected (O/E) ratios were calculated, and the models' predictive performances were compared using a nested c‐index approach. Linear regression analyses identified the subgroup of risk factors driving the differences observed. Results Mortality rates were 3%, 9%, and 17% at one‐, three‐, and five years, respectively (median follow‐up: five years). The clinical risk model provided more accurate predictions. Greater divergence between model estimates occurred with increasing long‐term mortality risk, with baseline renal dysfunction identified as a particularly important driver of these differences. Conclusions Long‐term mortality clinical risk models provide enhanced predictive power compared to actuarial models. Using the Hannan risk model, a patient's long‐term mortality risk can be accurately assessed and subgroups of higher‐risk patients can be identified for enhanced follow‐up care. More research appears warranted to refine long‐term CABG clinical risk models. doi: 10.1111/jocs.12665 (J Card Surg 2016;31:23–30) PMID:26543019

    Rinkens Paula ELM

    2006-10-01

    Full Text Available Abstract Background Many risk factors for fractures have been documented, including low bone-mineral density (BMD and a history of fractures. However, little is known about the short-term absolute risk (AR of fractures and the timing of clinical fractures. Therefore, we assessed the risk and timing of incident clinical fractures, expressed as 5-year AR, in postmenopausal women. Methods In total, 10 general practice centres participated in this population-based prospective study. Five years after a baseline assessment, which included clinical risk factor evaluation and BMD measurement, 759 postmenopausal women aged between 50 and 80 years, were re-examined, including undergoing an evaluation of clinical fractures after menopause. Risk factors for incident fractures at baseline that were significant in univariate analyses were included in a multivariate Cox survival regression analysis. The significant determinants were used to construct algorithms. Results In the total group, 12.5% (95% confidence interval (CI 10.1–14.9 of the women experienced a new clinical fracture. A previous clinical fracture after menopause and a low BMD (T-score Conclusion In postmenopausal women, clinical fractures cluster in time. One in two women with a recent clinical fracture had a new clinical fracture within 5 years, regardless of BMD. The 5-year AR for a first clinical fracture was much lower and depended on BMD.

  5. Risk profile for Chlamydia infection in women from public health clinics in New York State.

    Han, Y; Morse, D L; Lawrence, C E; Murphy, D; Hipp, S

    1993-02-01

    The prevalence of chlamydial infection and associated risk factors were studied in 1531 women from ten clinics in New York State excluding New York City. Overall Chlamydia infection rates were 13.6%; 17.6% in eight high risk family planning and STD clinics, and 5.7% in two low risk college and private clinics. Risk factors for Chlamydia infection included: age oral contraceptives (odds ratio 2.0), a history of having more than one sexual partner (odds ratio 1.7) and, in one clinic where data was available, inflammation on Papanicolaou smears (odds ratio 2.1). These data helped secure funding for Chlamydia preventive services and permitted development of a risk profile (score card) of Chlamydia for each age group. Use of such a score card can be most helpful in assigning which patients could benefit most from Chlamydia cultures, especially in those areas where testing is unavailable or too costly to screen all patients.

  7. Nurse Practitioner Perceptions of a Diabetes Risk Assessment Tool in the Retail Clinic Setting.

    Marjama, Kristen L; Oliver, JoAnn S; Hayes, Jennifer

    2016-10-01

    IN BRIEF This article describes a study to gain insight into the utility and perceived feasibility of the American Diabetes Association's Diabetes Risk Test (DRT) implemented by nurse practitioners (NPs) in the retail clinic setting. The DRT is intended for those without a known risk for diabetes. Researchers invited 1,097 NPs working in the retail clinics of a nationwide company to participate voluntarily in an online questionnaire. Of the 248 NPs who sent in complete responses, 114 (46%) indicated that they used the DRT in the clinic. Overall mean responses from these NPs indicated that they perceive the DRT as a feasible tool in the retail clinic setting. Use of the DRT or similar risk assessment tools in the retail clinic setting can aid in the identification of people at risk for type 2 diabetes.

    2011-09-01

    Full Text Available Abstract Background Physicians involved in primary prevention are key players in CVD risk control strategies, but the expected reduction in CVD risk that would be obtained if all patients attending primary care had their risk factors controlled according to current guidelines is unknown. The objective of this study was to estimate the excess risk attributable, firstly, to the presence of CVD risk factors and, secondly, to the lack of control of these risk factors in primary prevention care across Europe. Methods Cross-sectional study using data from the European Study on Cardiovascular Risk Prevention and Management in Daily Practice (EURIKA, which involved primary care and outpatient clinics involved in primary prevention from 12 European countries between May 2009 and January 2010. We enrolled 7,434 patients over 50 years old with at least one cardiovascular risk factor but without CVD and calculated their 10-year risk of CVD death according to the SCORE equation, modified to take diabetes risk into account. Results The average 10-year risk of CVD death in study participants (N = 7,434 was 8.2%. Hypertension, hyperlipidemia, smoking, and diabetes were responsible for 32.7 (95% confidence interval 32.0-33.4, 15.1 (14.8-15.4, 10.4 (9.9-11.0, and 16.4% (15.6-17.2 of CVD risk, respectively. The four risk factors accounted for 57.7% (57.0-58.4 of CVD risk, representing a 10-year excess risk of CVD death of 5.66% (5.47-5.85. Lack of control of hypertension, hyperlipidemia, smoking, and diabetes were responsible for 8.8 (8.3-9.3, 10.6 (10.3-10.9, 10.4 (9.9-11.0, and 3.1% (2.8-3.4 of CVD risk, respectively. Lack of control of the four risk factors accounted for 29.2% (28.5-29.8 of CVD risk, representing a 10-year excess risk of CVD death of 3.12% (2.97-3.27. Conclusions Lack of control of CVD risk factors was responsible for almost 30% of the risk of CVD death among patients participating in the EURIKA Study.

    Several drugs used in the treatment of mental diseases are associated with an increased risk of sudden cardiac death (SCD). A general cause-relationship between the intake of these drugs and SCD is unattainable, but numerous case reports of drug-induced malignant arrhythmia and epidemiological studies, associating the use of specific drugs with SCD, strongly support the presence of an increased risk. Whereas the absolute risk of drug-induced life-threatening arrhythmia may be relatively low, even small increments in risk of SCD may have a major health impact considering that millions of patients are treated with psychotropics. In subgroups of pre-disposed patients, e.g. patients with cardiac diseases or other co-morbidities, the elderly or patients treated with other negatively interacting drugs, the absolute risk of drug-induced arrhythmia may be considerable. On the other hand, several of the major mental disorders are associated with a large risk of suicide if untreated. The observed risk of malignant arrhythmia associated with treatment with psychotropic drugs calls for clinical guidelines integrating the risk of the individual drug and other potentially interacting risk factors. In this review, data from various authorities on the risk of arrhythmia associated with psychotropic medications were weighted and categorized into three risk categories. Additionally, we suggest a clinically applicable algorithm to reduce the risk of malignant arrhythmia in patients to be treated with psychotropic medications. The algorithm integrates the risk categories of the individual drugs and pre-disposing risk factors and suggests a prudent follow-up for patients with an increased risk. We believe this clinically manageable guideline might improve safety in the many and rapidly increasing number of patients on psychotropic drugs.

    In response to a spate of serious untoward incident enquiries, CAMHS team leaders in East London, UK, embarked on a series of clinical risk workshops with staff teams. Complementary to what might be called retrospective organisational responses to high risk events, these prospective workshops were predicated on the idea that risk reduction is increased when individuals in teams are responsive to one another, when teams are positively risk-aware and when risk awareness is seen as having the capacity to predict what may go wrong in the future.

  5. Risk management in clinical practice. Part 4. Endodontics.

    Webber, J

    2010-08-28

    Endodontic procedures are challenging and technically demanding. In the UK standards of treatment have been shown to have fallen short of acceptable guidelines, laying many dentists open to litigation on questions of clinical negligence by patients who understand and know what should be considered as current best practice in this area. Failure to communicate with patients about the procedure and not obtaining consent for treatment is a key area of complaint, as is inadequate record keeping. When treatment is undertaken within the framework of accepted guidelines it would be very difficult for a patient to open a claim for clinical negligence should a failure occur. This article looks at potential dento-legal problems in endodontics and how, through compliance with best practice, they may be avoided.

  9. Data-driven risk identification in phase III clinical trials using central statistical monitoring.

    Timmermans, Catherine; Venet, David; Burzykowski, Tomasz

    2016-02-01

    Our interest lies in quality control for clinical trials, in the context of risk-based monitoring (RBM). We specifically study the use of central statistical monitoring (CSM) to support RBM. Under an RBM paradigm, we claim that CSM has a key role to play in identifying the "risks to the most critical data elements and processes" that will drive targeted oversight. In order to support this claim, we first see how to characterize the risks that may affect clinical trials. We then discuss how CSM can be understood as a tool for providing a set of data-driven key risk indicators (KRIs), which help to organize adaptive targeted monitoring. Several case studies are provided where issues in a clinical trial have been identified thanks to targeted investigation after the identification of a risk using CSM. Using CSM to build data-driven KRIs helps to identify different kinds of issues in clinical trials. This ability is directly linked with the exhaustiveness of the CSM approach and its flexibility in the definition of the risks that are searched for when identifying the KRIs. In practice, a CSM assessment of the clinical database seems essential to ensure data quality. The atypical data patterns found in some centers and variables are seen as KRIs under a RBM approach. Targeted monitoring or data management queries can be used to confirm whether the KRIs point to an actual issue or not.

  10. Ethical implications for clinical practice and future research in "at risk" individuals.

    The last 15 years have witnessed a shift in schizophrenia research with increasing interest in earlier stages of illness with the hope of early intervention and ultimately prevention of psychotic illness. Large-scale longitudinal studies have identified clinical and biological risk factors associated with increased risk of psychotic conversion, which together with symptomatic and demographic risk factors may improve the power of prediction algorithms for psychotic transition. Despite these advances, 45-70% of at risk subjects in most samples do not convert to frank psychosis, but continue to function well below their age matched counterparts. The issue is of utmost importance in light of the upcoming DSM-V and the possible inclusion of the attenuated psychotic symptoms syndrome (APSS) diagnosis, with clinical and ethical implications. Clinical considerations include feasibility of reliably diagnosing the at risk state in non-academic medical centers, variable psychotic conversion rates, a non-uniform definition of conversion and extensive debate about treatment for individuals with an ill-defined outcome. On the ethical side, diagnosing APSS could lead to unnecessary prescribing of antipsychotics with long-term deleterious consequences, slow research by providing a false sense of comfort in the diagnosis, and have psychosocial implications for those who receive a diagnosis. Thus it may be prudent to engage at risk populations early and to use broad-spectrum treatments with low risk benefit ratios to relieve functional impairments, while simultaneously studying all subsets of the at risk population.

  11. [Sarcoidosis: etiology, pathogenesis, epidemiology, risk factors, clinical presentation].

    Éksarenko, O V; Kharlap, S I; Safonova, T N

    2012-01-01

    Sarcoidosis is a chronic idiopathic multisystem granulomatous inflammatory disease of unknown etiology. Prevalence of this condition is approximately 3-5: 100 000 with the highest incidence at the age of 25-40 years old and no gender predomination. Early morbidity, disability and severe prognosis worsen patient's condition and make them socially limited. In some cases ocular involvement and vision loss aggravate general condition of the patients. Ocular involvement in sarcoidosis occurs in 10-75% patients. At the same time some data confirm the fact that in 7% of patients ocular damage is the presenting sign making them come to an ophthalmologist whereas orbital involvement may present in systemic disease only. Unclear etiology and clinical similarity with other conditions cause difficulties in early diagnosis and monitoring of patients with sarcoidosis.

    Full Text Available The continuously growing incidence of the neoplasic disease, estimated to be in 2020 themain cause of death in developed countries, has imposed an increasing research to discover newclasses of antineoplasic agents, which alone or in combination with classical chemotherapy agents,may turn cancer into a curable disease for the most of the patients. All these drugs affect the heart inrelation to the presence of risk factors: physiological (age, sex, race, general (malaise, pre-existingchronic diseases, pre-existing cardiovascular affections, previous mediastinal radiation therapy,association with other cardiotoxic substances, as well as in relation to factors related to medication(high daily dose, high cumulative dose, short interval between administrations, bolus injection. Themechanism that produces cardiotoxicity is incompletely elucidated, it appears to be plurifactorial, theproduction of oxygen free radicals being the main cause of morphological alterations. Anthracyclinescardiotoxicity is better known, with its two forms (acute/subacute and late or chronic or even thedelayed cardiotoxicity form in survivors of childhood cancers. There are also presented some cardiacdamage modalities after treatment with alkylating agents, antimetabolites, taxanes, monoclonalantibodies (trastuzumab.

  13. Type 2 diabetes in children: Clinical aspects and risk factors.

    Rao, P V

    2015-04-01

    A strong link between obesity, insulin resistance, and metabolic syndrome has been reported with development of a new paradigm to type 2 diabetes mellitus (T2DM), with some evidence suggesting that beta-cell dysfunction is present before the onset of impaired glucose tolerance. Differentiating type 1 diabetes mellitus (T1DM) from T2DM is actually not very easy and there exists a number of overlapping characteristics. The autoantibody frequencies of seven antigens in T1DM patients may turn out to be actually having T2DM patients (pre-T2DM). T2DM patients generally have increased C-peptide levels (may be normal at time of diagnosis), usually no auto-antibodies, strong family history of diabetes, obese and show signs of insulin resistance (hypertension, acanthosis, PCOS). The American Academy of Paediatrics recommends lifestyle modifications ± metformin when blood glucose is 126-200 mg/dL and hemoglobin A1c (HbA1c) 200 mg/dL and HbA1c >8.5, with or without ketosis. Metformin is not recommended if the patient is ketotic, because this increases the risk of lactic acidosis. Metformin is currently the only oral hypoglycemic that has been approved for use in children. Knowing these subtle differences in mechanism, and knowing how to test patients for which mechanism (s) are causing their diabetes mellitus, may help us eventually tailor treatment programs on an individual basis.

    This study was conducted to assess (1) levels of volatile organic compounds (VOCs) and particulate matter (PM) in a dental clinic in southern Taiwan and (2) dental care personnel's health risks associated with due to chronic exposure to VOCs. An automatic, continuous sampling system and a multi-gas monitor were employed to quantify the air pollutants, along with environmental comfort factors, including temperature, CO2, and relative humidity at six sampling sites in the clinic over eight days. Specific VOC compounds were identified and their concentrations were quantified. Both non-carcinogenic and carcinogenic VOC compounds were assessed based on the US Environmental Protection Agency's Principles of Health Risk Assessment in terms of whether those indoor air pollutants increased health risks for the full-time dental care professionals at the clinic. Increased levels of VOCs were recorded during business hours and exceeded limits recommended by the Taiwan Environmental Protection Agency. A total of 68 VOC compounds were identified in the study area. Methylene methacrylate (2.8 ppm) and acetone (0.176 ppm) were the only two non-carcinogenic compounds that posed increased risks for human health, yielding hazard indexes of 16.4 and 4.1, respectively. None of the carcinogenic compounds increased cancer risk. All detected PM10 levels ranged from 20 to 150 μg/m(3), which met the Taiwan EPA and international limits. The average PM10 level during business hours was significantly higher than that during non-business hours (P = 0.04). Improved ventilation capacity in the air conditioning system was recommended to reduce VOCs and PM levels.

  16. Actuarial assessment of violence risk in hospital-based partner assault clinics.

    Hilton, N Zoe; Harris, Grant T; Holder, Norah

    2008-12-01

    Hospital-based partner assault clinics are a relatively recent addition to the community response to partner violence. In this study, 66% of 111 women attending hospital clinics for partner assault were physically injured and 43% reported death threats. Few concurrently used other services (shelters or police) and most relied on female friends and relatives for help. Many participants who currently lived with the perpetrator were contemplating leaving but only a third had made plans to do so. Participants faced an unusually high risk of future assault, according to both victim interview using the ODARA actuarial risk assessment and their own perceptions. Findings imply an important role for partner assault clinics and the feasibility of the victim service sector's using the same actuarial risk assessments as the criminal justice system.

  17. Nonconsensual clinical trials: a foreseeable risk of offshoring under global corporatism.

    Spielman, Bethany

    2015-03-01

    This paper explores the connection of offshoring and outsourcing to nonconsensual global pharmaceutical trials in low-income countries. After discussing reasons why the topic of nonconsensual offshored clinical trials may be overlooked in bioethics literature, I suggest that when pharmaceutical corporations offshore clinical trials today, nonconsensual experiments are often foreseeable and not simply the result of aberrant ethical conduct by a few individuals. Offshoring of clinical trials is structured so that experiments can be presented as health care in a unique form of outsourcing from the host country to pharmaceutical corporations. Bioethicists' assessments of the risks and potential benefits of offshore corporate pharmaceutical trials should therefore systematically include not only the hoped for benefits and the risks of the experimental drug but also the risk that subjects will not have consented, as well as the broader international consequences of nonconsensual experimentation.

  18. Towards individualized dose constraints: Adjusting the QUANTEC radiation pneumonitis model for clinical risk factors

    Appelt, Ane L; Vogelius, Ivan R.; Farr, Katherina P.;

    2014-01-01

    Background. Understanding the dose-response of the lung in order to minimize the risk of radiation pneumonitis (RP) is critical for optimization of lung cancer radiotherapy. We propose a method to combine the dose-response relationship for RP in the landmark QUANTEC paper with known clinical risk...... factors, in order to enable individual risk prediction. The approach is validated in an independent dataset. Material and methods. The prevalence of risk factors in the patient populations underlying the QUANTEC analysis was estimated, and a previously published method to adjust dose......-response relationships for clinical risk factors was employed. Effect size estimates (odds ratios) for risk factors were drawn from a recently published meta-analysis. Baseline values for D50 and γ50 were found. The method was tested in an independent dataset (103 patients), comparing the predictive power of the dose......-only QUANTEC model and the model including risk factors. Subdistribution cumulative incidence functions were compared for patients with high/low-risk predictions from the two models, and concordance indices (c-indices) for the prediction of RP were calculated. Results. The reference dose- response relationship...

  19. A novel neural-inspired learning algorithm with application to clinical risk prediction.

    Tay, Darwin; Poh, Chueh Loo; Kitney, Richard I

    2015-04-01

    Clinical risk prediction - the estimation of the likelihood an individual is at risk of a disease - is a coveted and exigent clinical task, and a cornerstone to the recommendation of life saving management strategies. This is especially important for individuals at risk of cardiovascular disease (CVD) given the fact that it is the leading causes of death in many developed counties. To this end, we introduce a novel learning algorithm - a key factor that influences the performance of machine learning-based prediction models - and utilities it to develop CVD risk prediction tool. This novel neural-inspired algorithm, called the Artificial Neural Cell System for classification (ANCSc), is inspired by mechanisms that develop the brain and empowering it with capabilities such as information processing/storage and recall, decision making and initiating actions on external environment. Specifically, we exploit on 3 natural neural mechanisms responsible for developing and enriching the brain - namely neurogenesis, neuroplasticity via nurturing and apoptosis - when implementing ANCSc algorithm. Benchmark testing was conducted using the Honolulu Heart Program (HHP) dataset and results are juxtaposed with 2 other algorithms - i.e. Support Vector Machine (SVM) and Evolutionary Data-Conscious Artificial Immune Recognition System (EDC-AIRS). Empirical experiments indicate that ANCSc algorithm (statistically) outperforms both SVM and EDC-AIRS algorithms. Key clinical markers identified by ANCSc algorithm include risk factors related to diet/lifestyle, pulmonary function, personal/family/medical history, blood data, blood pressure, and electrocardiography. These clinical markers, in general, are also found to be clinically significant - providing a promising avenue for identifying potential cardiovascular risk factors to be evaluated in clinical trials.

    Bucci, C. M.; Legnani, W. E.; Armentano, R. L.

    2016-04-01

    The scope of this work is to show another way to grouping population with clinical variables measured in health centres and to assign a cardiovascular risk indicator. To do this, two different datasets were used, one coming from France and another coming from Uruguay. The well proved Framingham index was used to validate the results. The preliminary results are very auspicious to encourage the research and get deeper knowledge of the cardiovascular risk indicators.

  2. External model validation of binary clinical risk prediction models in cardiovascular and thoracic surgery.

    Hickey, Graeme L; Blackstone, Eugene H

    2016-08-01

    Clinical risk-prediction models serve an important role in healthcare. They are used for clinical decision-making and measuring the performance of healthcare providers. To establish confidence in a model, external model validation is imperative. When designing such an external model validation study, thought must be given to patient selection, risk factor and outcome definitions, missing data, and the transparent reporting of the analysis. In addition, there are a number of statistical methods available for external model validation. Execution of a rigorous external validation study rests in proper study design, application of suitable statistical methods, and transparent reporting.

    Despite recent progress in prediction and prevention, heart disease remains a leading cause of death. One preliminary step in heart disease prediction and prevention is risk factor identification. Many studies have been proposed to identify risk factors associated with heart disease; however, none have attempted to identify all risk factors. In 2014, the National Center of Informatics for Integrating Biology and Beside (i2b2) issued a clinical natural language processing (NLP) challenge that involved a track (track 2) for identifying heart disease risk factors in clinical texts over time. This track aimed to identify medically relevant information related to heart disease risk and track the progression over sets of longitudinal patient medical records. Identification of tags and attributes associated with disease presence and progression, risk factors, and medications in patient medical history were required. Our participation led to development of a hybrid pipeline system based on both machine learning-based and rule-based approaches. Evaluation using the challenge corpus revealed that our system achieved an F1-score of 92.68%, making it the top-ranked system (without additional annotations) of the 2014 i2b2 clinical NLP challenge.

    2016-01-01

    Chronic myelomonocytic leukemia (CMML) is a myelodysplastic/myeloproliferative neoplasm with variable clinical course. To predict the clinical outcome, we previously developed a CMML-specific prognostic scoring system (CPSS) based on clinical parameters and cytogenetics. In this work, we tested the hypothesis that accounting for gene mutations would further improve risk stratification of CMML patients. We therefore sequenced 38 genes to explore the role of somatic mutations in disease phenotype and clinical outcome. Overall, 199 of 214 (93%) CMML patients carried at least 1 somatic mutation. Stepwise linear regression models showed that these mutations accounted for 15% to 24% of variability of clinical phenotype. Based on multivariable Cox regression analyses, cytogenetic abnormalities and mutations in RUNX1, NRAS, SETBP1, and ASXL1 were independently associated with overall survival (OS). Using these parameters, we defined a genetic score that identified 4 categories with significantly different OS and cumulative incidence of leukemic evolution. In multivariable analyses, genetic score, red blood cell transfusion dependency, white blood cell count, and marrow blasts retained independent prognostic value. These parameters were included into a clinical/molecular CPSS (CPSS-Mol) model that identified 4 risk groups with markedly different median OS (from >144 to 18 months, hazard ratio [HR] = 2.69) and cumulative incidence of leukemic evolution (from 0% to 48% at 4 years, HR = 3.84) (P < .001). The CPSS-Mol fully retained its ability to risk stratify in an independent validation cohort of 260 CMML patients. In conclusion, integrating conventional parameters and gene mutations significantly improves risk stratification of CMML patients, providing a robust basis for clinical decision-making and a reliable tool for clinical trials.

    Although multiple-use dental napkin holders have a relatively low risk of transmitting infection, they do require disinfection between patients. This study sought to: 1) determine the presence of bacterial load on two types of clips of reusable bib chains after dental procedures at the Endodontics and Orthodontics clinics at Tufts University School of Dental Medicine; and 2) evaluate the effectiveness of disinfecting the clips. These specialty clinics represent a wide spectrum of patients, procedures, and appointment times. Bacterial load on the bib clips was determined immediately following dental treatments-both before and after their disinfection-during morning and afternoon sessions. The results revealed that, after treatments, there was a statistically significant difference when comparing the two clinics for bacterial burden on the clips. Furthermore, there was a statistically significant difference in bacterial load on the two types of clips. Disinfection of the bib clips was highly effective in both clinics. Clinically, the results suggest that due to the nature of the treatment, the demographic population, and the type of bib clips used, patients in different clinics may be exposed to varying bacterial concentrations on the bib clips, and thus to different possible cross-contamination risks. Future analyses will be performed to identify the bacterial species in samples from both pre- and post-disinfected clips, and to determine if they harbor disease-causing bacterial species that can pose a potential, yet undetermined risk for cross-contamination.

  8. Building a normative decision support system for clinical and operational risk management in hemodialysis.

    Cornalba, Chiara; Bellazzi, Roberto G; Bellazzi, Riccardo

    2008-09-01

    This paper describes the design and implementation of a decision support system for risk management in hemodialysis (HD) departments. The proposed system exploits a domain ontology to formalize the problem as a Bayesian network. It also relies on a software tool, able to automatically collect HD data, to learn the network conditional probabilities. By merging prior knowledge and the available data, the system allows to estimate risk profiles both for patients and HD departments. The risk management process is completed by an influence diagram that enables scenario analysis to choose the optimal decisions that mitigate a patient's risk. The methods and design of the decision support tool are described in detail, and the derived decision model is presented. Examples and case studies are also shown. The tool is one of the few examples of normative system explicitly conceived to manage operational and clinical risks in health care environments.

  9. Clinical Risk Factors For Central Line Associated Venous Thrombosis (CLAVT In Children

    Samir H Shah

    2015-05-01

    Full Text Available ABSTRACTBackground: Identifying risk factors related to Central Venous Line (CVL placement could potentially minimize Central Line-Associated Venous Thrombosis (CLAVT. We sought to identify the clinical factors associated with CLAVT in children. Methods: Over a 3-year period, 3,733 CVLs were placed at a tertiary-care children’s hospital. Data were extracted from the electronic medical records of patients with clinical signs and symptoms of venous thromboembolism (VTE, diagnosed using Doppler ultrasonography and/or echocardiography. Statistical analyses examined differences in CLAVT occurrence between groups based on patient and CVL characteristics (type, brand, placement site, and hospital unit. Results: Femoral CVL placement was associated with greater risk for developing CLAVT (OR 11.1, 95% CI 3.9-31.6, p<0.0001. CVLs placed in the NICU were also associated with increased CLAVT occurrence (OR 5.3, 95% CI 2.1-13.2, p=0.0003. CVL brand was also significantly associated with risk of CLAVT events. Conclusion: Retrospective analyses identified femoral CVL placement and catheter type as independent risk factors for CLAVT, suggesting increased risks due to mechanical reasons. Placement of CVLs in the NICU also led to an increased risk of CLAVT, suggesting that small infants are at increased risk of thrombotic events. Alternative strategies for CVL placement, thromboprophylaxis, and earlier diagnosis may be important for reducing CLAVT events.

The possibility of avoiding new caries lesions increased 5% in both groups and a discrete increase was observed in the other parameters. Conclusion: It can be concluded that the Nexø system associated with the Cariogram® (School of Dentistry, Malmö, Sweden, contributed to the assessment of the patients’ caries risk profile and to the success of the preventive program for children at the cariology clinic at Universidade Federal da Paraíba.

  11. Cow-specific risk factors for clinical mastitis in Brazilian dairy cattle.

    Oliveira, C S F; Hogeveen, H; Botelho, A M; Maia, P V; Coelho, S G; Haddad, J P A

    2015-10-01

    Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which risk factors were associated with the occurrence of the most common pathogens involved in Brazilian CM infections. The analyses were based on 65 months of data from 9,789 dairy cows and 12,464 CM cases. Cow-specific risk factors that could easily be measured in standard Brazilian dairy farms were used in the statistical analyses, which included logistic regression and multinomial logistic regression. The first month of lactation, high somatic cell count, rainy season and history of clinical mastitis cases were factors associated with CM for both primiparous and multiparous cows. In addition, parity and breed were also associated risk factors for multiparous cows. Of all CM cases, 54% showed positive bacteriological culturing results from which 57% were classified as environmental pathogens, with a large percentage of coliforms (35%). Coagulase-negative Staphylococcus (16%), Streptococcus uberis (9%), Streptococcus agalactiae (7%) and other Streptococci (9%) were also common pathogens. Among the pathogens analyzed, the association of cow-specific risk factors, such as Zebu breed (OR=5.84, 95%CI 3.77-10.77) and accumulated history of SCC (1.76, 95%CI 1.37-2.27), was different for CM caused by Coagulase-negative Staphylococcus and S. agalactiae in comparison to CM caused by coliforms. Our results suggest that CM control programs in Brazil should specially consider the recent history of clinical mastitis cases and the beginning of the lactations, mainly during the rainy season as important risk factor for mastitis.

  12. Correlation between Timi Risk Score and Clinical Outcome in Patients with Unstable Angina Pectoris

    Savovic Zorica

    2016-06-01

    Full Text Available Given Taking that the TIMI score is a major predictor of MACE, this study aimed to determine the value of the TIMI risk score in predicting poor outcomes (death, myocardial infarction, recurrent pain in patients presenting with unstable angina pectoris in short-term observation. A total of 107 patients with APns were examined at the Clinical Centre Kragujevac and were included in the investigation. The TIMI score was determined on the first day of hospitalization. During hospitalization, the following factors were also observed: troponin, ECG evolution, further therapy (pharmacologic therapy and/or emergency PCI or CABG, age, hypertension and hyperlipidaemia. The low-risk group (TIMI 0 - 2 included 30.8% of patients, whereas 47.6% of patients were in the intermediate-risk group (TIMI 3 - 4, and 21.5% of patients were in the high-risk group (TIMI 5 - 7. Good outcomes (without adverse event and poor outcomes (death, myocardial infarction, and recurring chest pain were dependent on the TIMI risk score. The increase in TIMI risk score per one unit increased the risk of a poor outcome by 54%. Troponin and TIMI risk score were positively correlated. Our results suggest that the TIMI risk score may be a reliable predictor of a poor outcome (MACE during the short-term observation of patients with APns. Moreover, patients identified as high-risk benefit from early invasive PCI, enoxaparin and Gp IIb/IIIa inhibitors. Th us, routine use of the TIMI risk score at admission may reduce the number of patients not recognized as high-risk.

  13. A Mobile Clinical Decision Support Tool for Pediatric Cardiovascular Risk-Reduction Clinical Practice Guidelines: Development and Description

    2017-01-01

    Background Widespread application of research findings to improve patient outcomes remains inadequate, and failure to routinely translate research findings into daily clinical practice is a major barrier for the implementation of any evidence-based guideline. Strategies to increase guideline uptake in primary care pediatric practices and to facilitate adherence to recommendations are required. Objective Our objective was to operationalize the US National Heart, Lung, and Blood Institute’s Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents into a mobile clinical decision support (CDS) system for healthcare providers, and to describe the process development and outcomes. Methods To overcome the difficulty of translating clinical practice guidelines into a computable form that can be used by a CDS system, we used a multilayer framework to convert the evidence synthesis into executable knowledge. We used an iterative process of design, testing, and revision through each step in the translation of the guidelines for use in a CDS tool to support the development of 4 validated modules: an integrated risk assessment; a blood pressure calculator; a body mass index calculator; and a lipid management instrument. Results The iterative revision process identified several opportunities to improve the CDS tool. Operationalizing the integrated guideline identified numerous areas in which the guideline was vague or incorrect and required more explicit operationalization. Iterative revisions led to workable solutions to problems and understanding of the limitations of the tool. Conclusions The process and experiences described provide a model for other mobile CDS systems that translate written clinical practice guidelines into actionable, real-time clinical recommendations.

    Conclusion: The prevalence of bacterial infection in patients with NTDT was found to be moderate. Time after splenectomy >10 years, deferoxamine therapy, and iron overload may be clinical risk factors for severe bacterial infection in patients with NTDT. Bacterial infection should be recognized in splenectomized patients with NTDT, particularly those who have an iron overload.

    2016-06-01

    Full Text Available Background Infection in the immunocompromised host has been a reason of concern in the clinical setting and a topic of debate for decades. In this study, the aim was to analyse the clinical profile of high-risk febrile neutropenic patients. Aims To study the clinical profile of high risk febrile neutropenia patients with the objective of identifying the most common associated malignancy, most common associated pathogen, the source of infection, to correlate the treatment and management with that of the Infectious Diseases Society of America (IDSA 2010 guidelines and to assess the clinical outcome. Methods A cross-sectional time bound study was carried out and a total of 80 episodes of high-risk febrile neutropenia were recorded among patients with malignancies from September 2011 to July 2013 with each episode being taken as a new case. Results Non-Hodgkin’s lymphoma (30 per cent was the most common malignancy associated, commonest source of infection was due to central venous catheters, the commonest pathogens were gram negative (52 per cent the treatment and management of each episode of high risk febrile neutropenia correlated with that of IDSA 2010 guidelines and the mortality rate was 13.75 per cent. Conclusion Febrile neutropenia is one of the major complications and cause of mortality in patients with malignancy and hence understanding its entire spectrum can help us reduce morbidity and mortality.

  9. High heart rate: more than a risk factor. Lessons from a clinical practice survey.

    Barrios, Vivencio; Escobar, Carlos; Bertomeu, Vicente; Murga, Nekane; de Pablo, Carmen; Asín, Enrique

    2009-11-12

    Several epidemiological studies have reported that an elevated heart rate (HR) is associated with coronary atherosclerosis independently of other risk factors. Nevertheless, it is still unclear whether HR is itself the cause or there is merely an association between HR and mortality in this population. A total of 1686 patients with hypertension and chronic ischemic heart disease were included in this study. According to the resting HR, the patients were distributed in 3 groups (group 1: HR82 bpm). 580 patients (34.4%) belonged to group 1; 936 (55.5%) to group 2 and 170 (10.1%) to group 3. Patients with high HR exhibited a poorer prognosis not only due to a worse clinical profile (more concomitant cardiovascular risk factors and organ damage), but suggestively because despite the use of a similar number of drugs, patients with higher HR were associated with lesser risk control rates in daily clinical practice. Despite current guidelines that do not still recognize HR as a cardiovascular risk factor, it appears that physicians should pay more attention to it in clinical practice since high HR is warning about an increased risk.

  10. Clinical signs, therapy and zoonotic risk of pet guinea pigs with dermatophytosis.

    2013-03-01

    Systematic studies about pet guinea pigs with dermatophytosis are rare. The aim of this study was to evaluate clinical signs, therapy and zoonotic risk of pet guinea pigs with dermatophytosis. Questionnaires from both owners (n = 74) of pet guinea pigs with dermatophytosis and their veterinarians (n = 101) were analysed regarding clinical signs, therapy and data pertinent to zoonotic potential. Trichophyton (T.) mentagrophytes was found in 97% of cases. In the weeks preceding the onset of the clinical signs, a new guinea pig joined the household in 43% of cases. One third of the affected guinea pigs had lived in the household for less than 3 months. Predominant clinical signs were alopecia (83%), scaling (73%) and crusting (70%). The most commonly affected body site was the head (75%). In approximately one quarter of the cases humans showed clinical signs of dermatophytosis, in half the households, only children were affected. Skin lesions were seen most often on the face, the neck and the arms. Pet guinea pigs carrying dermatophytes must be considered a serious zoonotic risk for their owners, especially for children. A major risk factor for dermatophytosis seems to be a recent acquisition of a new guinea pig.

    The chronic inflammation induced by human immunodeficiency virus (HIV) contributes to increased risk of coronary heart disease (CHD) in HIV-infected individuals. HIV-infected patients generally benefit from being treated with antiretroviral drugs, but some antiretroviral agents have side effects, such as dyslipidemia and hyperglycemia. There is general consensus that antiretroviral drugs induce a long-term risk of CHD, although the levels of that risk are somewhat controversial. The intention of this cross-sectional study was to describe the lipid profile and the long-term risk of CHD among HIV-positive outpatients at an HIV treatment clinic in Harare, Zimbabwe. Two hundred and fifteen patients were investigated (females n=165, mean age 39.8 years; males n=50; mean age 42.0 years). Thirty of the individuals were antiretroviral-naïve and 185 had been on antiretroviral therapy (ART) for a mean 3.9±3.4 years. All participants had average lipid and glucose values within normal ranges, but there was a small difference between the ART and ART-for total cholesterol (TC) and high-density lipoprotein (HDL). Those on a combination of D4T or ZDV/NVP/3TC and PI-based ART were on average oldest and had the highest TC levels. Framingham risk showed 1.4% prevalence of high CHD risk within the next ten years. After univariate analysis age, sex, TC/HDL ratio, HDL, economic earnings and systolic BP were associated with medium to high risk of CHD. After multivariate regression analysis and adjusting for age or sex only age, sex and economic earnings were associated with medium to high risk of CHD. There is small risk of developing CHD, during the next decade in HIV infected patients at an HIV treatment clinic in Harare.

    Hereditary breast cancer (HBC) accounts for 5-10% of breast cancer cases and it significantly increases the lifetime risk of cancer. Our objective was to evaluate the sociodemographic variables, family history of cancer, breast cancer (BC) screening practices and the risk profile of cancer affected or asymptomatic at-risk women that undergo genetic counseling for hereditary breast cancer in public Brazilian cancer genetics services. Estimated lifetime risk of BC was calculated for asymptomatic women using the Gail and Claus models. The majority of women showed a moderate lifetime risk of developing BC, with an average risk of 19.7% and 19.9% by the Gail and Claus models, respectively. The average prior probability of carrying a BRCA1/2 gene mutation was 16.7% and overall only 32% fulfilled criteria for a hereditary breast cancer syndrome as assessed by family history. We conclude that a significant number of individuals at high-risk for HBC syndromes may not have access to the benefits of cancer genetic counseling in these centers. Contributing factors may include insufficient training of healthcare professionals, disinformation of cancer patients; difficult access to genetic testing and/or resistance in seeking such services. The identification and understanding of these barriers is essential to develop specific strategies to effectively achieve cancer risk reduction in this and other countries were clinical cancer genetics is not yet fully established.

  13. Predictor characteristics necessary for building a clinically useful risk prediction model: a simulation study

    Laura Schummers

    2016-09-01

    Full Text Available Abstract Background Compelled by the intuitive appeal of predicting each individual patient’s risk of an outcome, there is a growing interest in risk prediction models. While the statistical methods used to build prediction models are increasingly well understood, the literature offers little insight to researchers seeking to gauge a priori whether a prediction model is likely to perform well for their particular research question. The objective of this study was to inform the development of new risk prediction models by evaluating model performance under a wide range of predictor characteristics. Methods Data from all births to overweight or obese women in British Columbia, Canada from 2004 to 2012 (n = 75,225 were used to build a risk prediction model for preeclampsia. The data were then augmented with simulated predictors of the outcome with pre-set prevalence values and univariable odds ratios. We built 120 risk prediction models that included known demographic and clinical predictors, and one, three, or five of the simulated variables. Finally, we evaluated standard model performance criteria (discrimination, risk stratification capacity, calibration, and Nagelkerke’s r2 for each model. Results Findings from our models built with simulated predictors demonstrated the predictor characteristics required for a risk prediction model to adequately discriminate cases from non-cases and to adequately classify patients into clinically distinct risk groups. Several predictor characteristics can yield well performing risk prediction models; however, these characteristics are not typical of predictor-outcome relationships in many population-based or clinical data sets. Novel predictors must be both strongly associated with the outcome and prevalent in the population to be useful for clinical prediction modeling (e.g., one predictor with prevalence ≥20 % and odds ratio ≥8, or 3 predictors with prevalence ≥10 % and odds ratios ≥4.

    2006-06-01

    Full Text Available Abstract Background The tuberculosis (TB epidemic in Africa is on the rise, even in low-HIV prevalence settings. Few studies have attempted to identify possible reasons for this. We aimed to identify risk factors for pulmonary tuberculosis in those attending a general outpatients clinic in The Gambia, a sub-Saharan African country with relatively low HIV prevalence in the community and in TB patients. Methods We conducted a case control study at the Medical Research Council Outpatients' clinic in The Gambia. Pulmonary TB cases were at least 15 years old, controls were age and sex matched clinic attendees. Participants were interviewed using a structured questionnaire. Results 100 sputum smear positive TB cases and 200 clinic controls were recruited. HIV prevalence was 6.1% in cases and 3.3% in controls. Multivariable assessment of host factors showed that risk of TB was increased among the Jola ethnic group and smokers, and decreased in those in a professional occupation. Assessment of environmental factors showed an increased risk with household crowding, history of household exposure to a known TB case, and absence of a ceiling in the house. In a combined multivariable host-environment model, the risk of TB increased with crowding, exposure to a known TB case, as well as amongst the Jola ethnic group. Conclusion In The Gambia, household crowding and past household exposure to a known TB case are the standout risk factors for TB disease. Further research is needed to identify why risk of TB seems to differ according to ethnicity.

  15. Predictive capacity of risk assessment scales and clinical judgment for pressure ulcers: a meta-analysis.

    García-Fernández, Francisco Pedro; Pancorbo-Hidalgo, Pedro L; Agreda, J Javier Soldevilla

    2014-01-01

    A systematic review with meta-analysis was completed to determine the capacity of risk assessment scales and nurses' clinical judgment to predict pressure ulcer (PU) development. Electronic databases were searched for prospective studies on the validity and predictive capacity of PUs risk assessment scales published between 1962 and 2010 in English, Spanish, Portuguese, Korean, German, and Greek. We excluded gray literature sources, integrative review articles, and retrospective or cross-sectional studies. The methodological quality of the studies was assessed according to the guidelines of the Critical Appraisal Skills Program. Predictive capacity was measured as relative risk (RR) with 95% confidence intervals. When 2 or more valid original studies were found, a meta-analysis was conducted using a random-effect model and sensitivity analysis. We identified 57 studies, including 31 that included a validation study. We also retrieved 4 studies that tested clinical judgment as a risk prediction factor. Meta-analysis produced the following pooled predictive capacity indicators: Braden (RR = 4.26); Norton (RR = 3.69); Waterlow (RR = 2.66); Cubbin-Jackson (RR = 8.63); EMINA (RR = 6.17); Pressure Sore Predictor Scale (RR = 21.4); and clinical judgment (RR = 1.89). Pooled analysis of 11 studies found adequate risk prediction capacity in various clinical settings; the Braden, Norton, EMINA (mEntal state, Mobility, Incontinence, Nutrition, Activity), Waterlow, and Cubbin-Jackson scales showed the highest predictive capacity. The clinical judgment of nurses was found to achieve inadequate predictive capacity when used alone, and should be used in combination with a validated scale.

    Little is known about the impact of enrollment on therapeutic clinical trials on adverse event rates. Primary objective was to describe the impact of clinical trial registration on sterile site microbiologically documented infection for children with newly diagnosed acute myeloid leukemia (AML). We conducted a multicenter cohort study that included children aged ≤18 years with de novo AML. Primary outcome was microbiologically documented sterile site infection. Infection rates were compared between those registered and not registered on clinical trials. Five hundred seventy-four children with AML were included of which 198 (34.5%) were registered on a therapeutic clinical trial. Overall, 400 (69.7%) had at least one sterile site microbiologically documented infection. In multiple regression, registration on clinical trials was independently associated with a higher risk of microbiologically documented sterile site infection [adjusted odds ratio (OR) 1.24, 95% confidence interval (CI) 1.01-1.53; p = 0.040] and viridans group streptococcal infection (OR 1.46, 95% CI 1.08-1.98; p = 0.015). Registration on trials was not associated with Gram-negative or invasive fungal infections. Children with newly diagnosed AML enrolled on clinical trials have a higher risk of microbiologically documented sterile site infection. This information may impact on supportive care practices in pediatric AML.

  17. The Clinical, Environmental, and Behavioral Factors That Foster Early Childhood Caries: Evidence for Caries Risk Assessment.

    Fontana, Margherita

    2015-01-01

    Caries risk assessment, an essential component of targeted health care delivery for young children, is of paramount importance in the current environment of increasing health care costs and resource constraints. The purpose of this manuscript was to review recent best available evidence behind the factors that influence caries risk assessment and the validity of strategies to assess the caries risk of young children. Moderate to weak evidence supports the following recommendations: (1) Children should have a caries risk assessment done in their first year (or as soon as their first tooth erupts) as part of their overall health assessment, and this should be reassessed periodically over time. (2) Multiple clinical, environmental, and behavioral factors should be considered when assessing caries risk in young children, including factors associated with the primary caregiver. (3) The use of structured forms, although most may not yet be validated, may aid in systematic assessment of multiple caries risk factors and in objective record-keeping. (4) Children from low socioeconomic status groups should be considered at increased risk when developing community preventive programs.

  19. The Prioritization of Clinical Risk Factors of Obstructive Sleep Apnea Severity Using Fuzzy Analytic Hierarchy Process

    Thaya Maranate

    2015-01-01

    Full Text Available Recently, there has been a problem of shortage of sleep laboratories that can accommodate the patients in a timely manner. Delayed diagnosis and treatment may lead to worse outcomes particularly in patients with severe obstructive sleep apnea (OSA. For this reason, the prioritization in polysomnography (PSG queueing should be endorsed based on disease severity. To date, there have been conflicting data whether clinical information can predict OSA severity. The 1,042 suspected OSA patients underwent diagnostic PSG study at Siriraj Sleep Center during 2010-2011. A total of 113 variables were obtained from sleep questionnaires and anthropometric measurements. The 19 groups of clinical risk factors consisting of 42 variables were categorized into each OSA severity. This study aimed to array these factors by employing Fuzzy Analytic Hierarchy Process approach based on normalized weight vector. The results revealed that the first rank of clinical risk factors in Severe, Moderate, Mild, and No OSA was nighttime symptoms. The overall sensitivity/specificity of the approach to these groups was 92.32%/91.76%, 89.52%/88.18%, 91.08%/84.58%, and 96.49%/81.23%, respectively. We propose that the urgent PSG appointment should include clinical risk factors of Severe OSA group. In addition, the screening for Mild from No OSA patients in sleep center setting using symptoms during sleep is also recommended (sensitivity = 87.12% and specificity = 72.22%.

  20. Knowledge of risk factors and the periodontal disease-systemic link in dental students' clinical decisions.

    2014-09-01

    This study evaluated second-, third-, and fourth-year dental students' ability to identify systemic conditions associated with periodontal disease, risk factors most important for referral, and medications with an effect on the periodontium and their ability to apply this knowledge to make clinical decisions regarding treatment and referral of periodontal patients. A twenty-one question survey was administered at one U.S. dental school in the spring semester of 2012 to elicit the students' knowledge and confidence regarding clinical reasoning. The response rate was 86 percent. Periodontal risk factors were accurately selected by at least 50 percent of students in all three classes; these were poorly controlled diabetes, ≥6 mm pockets posteriorly, and lack of response to previous non-surgical therapy. Confidence in knowledge, knowledge of risk factors, and knowledge of medications with an effect on the periodontium improved with training and were predictive of better referral decision making. The greatest impact of training was seen on the students' ability to make correct decisions about referral and treatment for seven clinical scenarios. Although the study found a large increase in the students' abilities from the second through fourth years, the mean of 4.6 (out of 7) for the fourth-year students shows that, on average, those students missed correct treatment or referral on more than two of seven clinical cases. These results suggest that dental curricula should emphasize more critical decision making with respect to referral and treatment criteria in managing the periodontal patient.

    2015-11-01

    Venous thrombosis is common in older age, with an incidence of 0·5-1% per year in those aged >70 years. Stasis of blood flow is an important contributor to the development of thrombosis and may be due to venous insufficiency in the legs. The risk of thrombosis associated with clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, obtained with a standardized interview was assessed in the Age and Thrombosis Acquired and Genetic risk factors in the Elderly (AT-AGE) study. The AT-AGE study is a case-control study in individuals aged 70 years and older (401 cases with a first-time venous thrombosis and 431 control subjects). We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CI) adjusted for age, sex and study centre. Varicose veins and leg ulcer were associated with a 1·6-fold (95% CI 1·2-2·3) and 3·3-fold increased risk of thrombosis (95% CI 1·6-6·7), respectively, while the risk was increased 3·0-fold (95% CI 2·1-4·5) in the presence of leg oedema. The risk of thrombosis was highest when all three risk factors occurred simultaneously (OR: 10·5; 95% CI 1·3-86·1). In conclusion, clinical features of venous insufficiency, i.e., varicose veins, leg ulcers and leg oedema, are risk factors for venous thrombosis in older people.

  2. Clinical potentials of methylator phenotype in stage 4 high-risk neuroblastoma: an open challenge.

    Barbara Banelli

    Full Text Available Approximately 20% of stage 4 high-risk neuroblastoma patients are alive and disease-free 5 years after disease onset while the remaining experience rapid and fatal progression. Numerous findings underline the prognostic role of methylation of defined target genes in neuroblastoma without taking into account the clinical and biological heterogeneity of this disease. In this report we have investigated the methylation of the PCDHB cluster, the most informative member of the "Methylator Phenotype" in neuroblastoma, hypothesizing that if this epigenetic mark can predict overall and progression free survival in high-risk stage 4 neuroblastoma, it could be utilized to improve the risk stratification of the patients, alone or in conjunction with the previously identified methylation of the SFN gene (14.3.3sigma that can accurately predict outcome in these patients. We have utilized univariate and multivariate models to compare the prognostic power of PCDHB methylation in terms of overall and progression free survival, quantitatively determined by pyrosequencing, with that of other markers utilized for the patients' stratification utilizing methylation thresholds calculated on neuroblastoma at stage 1-4 and only on stage 4, high-risk patients. Our results indicate that PCDHB accurately distinguishes between high- and intermediate/low risk stage 4 neuroblastoma in agreement with the established risk stratification criteria. However PCDHB cannot predict outcome in the subgroup of stage 4 patients at high-risk whereas methylation levels of SFN are suggestive of a "methylation gradient" associated with tumor aggressiveness as suggested by the finding of a higher threshold that defines a subset of patients with an extremely severe disease (OS <24 months. Because of the heterogeneity of neuroblastoma we believe that clinically relevant methylation markers should be selected and tested on homogeneous groups of patients rather than on patients at all stages.

  3. A fuzzy logic decision support system for assessing clinical nutritional risk

    Ali Mohammad Hadianfard

    2015-04-01

    Full Text Available Introduction: Studies have indicated a global high prevalence of hospital malnutrition on admission and during hospitalization. Clinical Nutritional Risk Screen (CNRS is a way to identify malnutrition and manage nutritional interventions. Several traditional and non-computer based tools have been suggested for screening nutritional risk levels. The present study was an attempt to employ a computer based fuzzy model decision support system as a nutrition-screening tool for inpatients. Method: This is an applied modeling study. The system architecture was designed based on the fuzzy logic model including input data, inference engine, and output. A clinical nutritionist entered nineteen input variables using a windows-based graphical user interface. The inference engine was involved with knowledge obtained from literature and the construction of ‘IF-THEN’ rules. The output of the system was stratification of patients into four risk levels from ‘No’ to ‘High’ where a number was also allocated to them as a nutritional risk grade. All patients (121 people admitted during implementing the system participated in testing the model. The classification tests were used to measure the CNRS fuzzy model performance. IBM SPSS version 21 was utilized as a tool for data analysis with α = 0.05 as a significance level. Results: Results showed that sensitivity, specificity, accuracy, and precision of the fuzzy model performance were 91.67% (±4.92, 76% (±7.6, 88.43% (±5.7, and 93.62% (±4.32, respectively. Instant performance on admission and very low probability of mistake in predicting malnutrition risk level may justify using the model in hospitals. Conclusion: To conclude, the fuzzy model-screening tool is based on multiple nutritional risk factors, having the capability of classifying inpatients into several nutritional risk levels and identifying the level of required nutritional intervention.

    A cross-sectional survey of dairy farms with low bulk milk somatic cell counts was carried out to assess the level of clinical mastitis and to quantify risk factors associated with the incidence rate of clinical mastitis. Questionnaires were sent to 3009 milk operations with an annual mean bulk milk somatic cell count of less than 100,000 cells/ml during 1997. A response rate was 61%. The mean incidence of clinical mastitis reported was 22.8 cases per 100 cows/yr. Negative binomial regression models were used to assess statistically significant risk factors associated with the incidence of clinical mastitis. The incidence increased when farmers reported that they had straw yard housing for milking cows (compared with cubicle housing), mucked out the calving area less frequently than once per month, kept cows standing in a yard after milking, always practiced postmilking teat disinfection, had greater than 50% replacement rate, had some cows that leaked milk on entry to the parlor, had some cows that leaked milk at other times, and foremilked before cluster attachment. The incidence of clinical mastitis was lower on farms when the gathering yard used before milking was scraped at least twice a day, cows were offered feed after both milkings, rubber gloves were not worn during milking, teat liners were changed after 6000 milkings, and the average dry period was less than 40 d. The study has identified areas of the environment in which efforts to improve hygiene should be focused.

In the present study, we assessed a version of this risk score that also included genetic information. Methods: Utilizing diagnostic testing methods, we hierarchically examined different prediction variables identified in previous NYPRS research, including genetic risk-allele information, to assess lifetime and current PTSD status among a population of trauma-exposed adults. Results: We found that, in predicting lifetime PTSD, the area under the receiver operating characteristic curve (AUC for the Primary Care PTSD Screen alone was 0.865. When we added psychosocial predictors from the original NYPRS to the model, including depression, sleep disturbance, and a measure of health care access, the AUC increased to 0.902, which was a significant improvement (P = 0.0021. When genetic information was added in the form of a count of PTSD risk alleles located within FKBP, COMT, CHRNA5, and CRHR1 genetic loci (coded 0–6, the AUC increased to 0.920, which was also a significant improvement (P = 0.0178. The results for current PTSD were similar. In the final model for current PTSD with the psychosocial risk factors included, genotype resulted in a prediction weight of 17 for each risk allele present, indicating that a person with six risk alleles or more would receive a PTSD risk score of 17 × 6 = 102, the highest risk score for any of the predictors studied. Conclusion: Genetic

    Objective Gout, caused by hyperuricaemia, is a multifactorial disease. Although genome-wide association studies (GWASs) of gout have been reported, they included self-reported gout cases in which clinical information was insufficient. Therefore, the relationship between genetic variation and clinical subtypes of gout remains unclear. Here, we first performed a GWAS of clinically defined gout cases only. Methods A GWAS was conducted with 945 patients with clinically defined gout and 1213 controls in a Japanese male population, followed by replication study of 1048 clinically defined cases and 1334 controls. Results Five gout susceptibility loci were identified at the genome-wide significance level (p<5.0×10−8), which contained well-known urate transporter genes (ABCG2 and SLC2A9) and additional genes: rs1260326 (p=1.9×10−12; OR=1.36) of GCKR (a gene for glucose and lipid metabolism), rs2188380 (p=1.6×10−23; OR=1.75) of MYL2-CUX2 (genes associated with cholesterol and diabetes mellitus) and rs4073582 (p=6.4×10−9; OR=1.66) of CNIH-2 (a gene for regulation of glutamate signalling). The latter two are identified as novel gout loci. Furthermore, among the identified single-nucleotide polymorphisms (SNPs), we demonstrated that the SNPs of ABCG2 and SLC2A9 were differentially associated with types of gout and clinical parameters underlying specific subtypes (renal underexcretion type and renal overload type). The effect of the risk allele of each SNP on clinical parameters showed significant linear relationships with the ratio of the case–control ORs for two distinct types of gout (r=0.96 [p=4.8×10−4] for urate clearance and r=0.96 [p=5.0×10−4] for urinary urate excretion). Conclusions Our findings provide clues to better understand the pathogenesis of gout and will be useful for development of companion diagnostics. PMID:25646370

  10. Rocky milieu: Challenges of effective integration of clinical risk management into hospitals in Iran

    Jamileh Farokhzadian

    2015-05-01

    Full Text Available Healthcare risks and clinical risks have been recognized as a major challenge in healthcare. Clinical risks can never be eliminated and can have serious adverse effects on patient safety. Thus, a clinical risk management (CRM system has been introduced in the healthcare system to improve quality services. The aim of this study was to explore nurses’ experiences related to the challenges of implementing CRM in the organizational context. This qualitative study was based on the conventional content analysis of the Lundman and Graneheim approach, and it consisted of 22 interview sessions with 20 nurses. The purposive sampling method was used to choose the participants from three hospitals affiliated with the Kerman University of Medical Sciences. We used semi-structured interviews and review of relevant documents to collect data. The analysis of the data led to the emergence of “rocky milieu” as the main theme, and it consisted of three categories that, along with their subcategories, explain the challenges of implementing CRM. The three categories and their subcategories were (1 organizational culture and leadership challenges (decision and performance of leadership and cultural resistance to change, (2 limitation of resources (financial, human, and physical and equipment resources, and (3 variations and complexities in working conditions (the emotional, psychological, and social atmosphere and the heaviness of workload. Attempts have been made to establish CRM through clinical governance and accreditation, but organizational challenges have created a rocky milieu for implementing CRM. However, from an organizational context concerning the suitability of healthcare in Iran, there are obvious needs to move toward quality improvement and safe practices through the effective implementation of CRM.

    AIM: There is still no accepted conclusion regarding the clinical features and related risk factors of patients with fatty liver. The large-scale clinical studies have not carried out yet in Guangzhou area. The aim of the present study was to investigate the clinical features and related risk factors of patients with fatty liver in Guangzhou area. METHODS: A total of 413 cases with fatty liver were enrolled in the study from January 1998 to May 2002. Retrospective case-control study was used to evaluate the clinical featuresand related risk factors of fatty liver with logistic regression.RESULTS: Obesity (OR: 21.204), alcohol abuse (OR: 18.601),type 2 diabetes mellitus (OR: 4.461), serum triglyceride (TG)(OR: 3.916), serum low-density lipoprotein cholesterol (LDL-C)(OR: 1.840) and fasting plasma glucose (FPG) (OR: 1.535)were positively correlated to the formation of the fatty liver. The levels of serum alanine aminotransferase (ALT) and gammaglutamyltransferase (GGT) increased mildly in the patients withfatty liver and were often less than 2-fold of the normal limit.The higher abnormalities of aspartate aminotransferase (AST)levels (42.9%) with Asr/ALT more than 2(17.9%) were found in patients with alcoholic fatty liver (AFL) than those with nonalcoholic fatty liver (NAFL) (16.9% and 5.0% respectively). The elevation of serum TG, cholesterol (CHOL), LDL-C was more common in patients with NAFL than with AFL.CONCLUSION: Obesity, alcohol abuse, type 2 diabetes mellitus and hyperlipidemia may be independent risk factors of fatty liver. The mildly abnormal hepatic functions can be found in patients with fatty liver. More obvious damages of liver function with AST/ALT usually more than 2 were noted in patients with AFL.

  14. Treatment referral for sex offenders based on clinical judgment versus actuarial risk assessment: match and analysis of mismatch.

    Smid, Wineke J; Kamphuis, Jan Henk; Wever, Edwin C; Van Beek, Daan

    2013-07-01

    The Risk Need Responsivity (RNR) principles (Andrews & Bonta, 2010) dictate that higher risk sex offenders should receive more intensive treatment. The present study investigates how clinically based treatment assignment relates to risk level in a sex offender sample from The Netherlands. Correlational analyses served to identify sources of mismatches: that is, variables differing significantly in their relation between treatment selection and risk level. Our study sample consisted of 194 convicted rapists and 214 convicted child molesters. All participants' criminal files were retrospectively coded in terms of the items of the STATIC-99R, PCL: SV, and SVR-20. A low to moderate correlation was observed between clinical treatment selection and actuarial risk levels. A substantial part of the sex offenders, especially child molesters, received overly intensive treatment and another substantial part, especially rapists, received treatment of lesser intensity than indicated by their risk levels. General violent and antisocial risk factors seemed to be underemphasized in the clinical evaluation of sex offenders, especially rapists. A negative attitude toward intervention was negatively associated with clinical treatment selection. It is concluded that clinical treatment selection leads to an insufficient match between risk level and treatment level and systematic use of validated structured risk assessment instruments is necessary to ensure optimal adherence to the risk principle.

    Gerweck, Leo E., E-mail: lgerweck@mgh.harvard.edu; Huang, Peigen; Lu, Hsiao-Ming; Paganetti, Harald; Zhou, Yenong

    2014-05-01

    Purpose: To evaluate the life span and risk of cancer following whole-body exposure of mice to neutrons generated by a passively scattered clinical spread-out Bragg peak (SOBP) proton beam. Methods and Materials: Three hundred young adult female FVB/N mice, 152 test and 148 control, were entered into the experiment. Mice were placed in an annular cassette around a cylindrical phantom, which was positioned lateral to the mid-SOBP of a 165-MeV, clinical proton beam. The average distance from the edge of the mid-SOBP to the conscious active mice was 21.5 cm. The phantom was irradiated with once-daily fractions of 25 Gy, 4 days per week, for 6 weeks. The age at death and cause of death (ie, cancer and type vs noncancer causes) were assessed over the life span of the mice. Results: Exposure of mice to a dose of 600 Gy of proton beam–generated neutrons, reduced the median life span of the mice by 4.2% (Kaplan-Meier cumulative survival, P=.053). The relative risk of death from cancer in neutron exposed versus control mice was 1.40 for cancer of all types (P=.0006) and 1.22 for solid cancers (P=.09). For a typical 60 Gy dose of clinical protons, the observed 22% increased risk of solid cancer would be expected to decrease by a factor of 10. Conclusions: Exposure of mice to neutrons generated by a proton dose that exceeds a typical course of radiation therapy by a factor of 10, resulted in a statistically significant increase in the background incidence of leukemia and a marginally significant increase in solid cancer. The results indicate that the risk of out-of-field second solid cancers from SOBP proton-generated neutrons and typical treatment schedules, is 6 to 10 times less than is suggested by current neutron risk estimates.

    2014-01-01

    Full Text Available Colorectal cancer (CRC is the third common carcinoma with a high rate of mortality worldwide and several studies have investigated some molecular and clinicopathological markers for diagnosis and prognosis of its malignant phenotypes. The aim of this study is to evaluate expression frequency of PAGE4, SCP-1, and SPANXA/D cancer testis antigen (CTA genes as well as some clinical risk markers to predict liver metastasis of colorectal cancer patients. The expression frequency of PAGE4, SCP-1, and SPANXA/D cancer/testis antigen (CTA genes was obtained using reverse transcription polymerase chain reaction (RT-PCR assay in 90 colorectal tumor samples including both negative and positive liver metastasis tumors. Statistical analysis was performed to assess the association of three studied genes and clinical risk factors with CRC liver metastasis. The frequency of PAGE4 and SCP-1 genes expression was significantly higher in the primary tumours with liver metastasis when statistically compared with primary tumors with no liver metastasis (P<0.05. Among all clinical risk factors studied, the lymph node metastasis and the depth of invasion were statistically correlated with liver metastasis of CRC patients. In addition, using multiple logistic regression, we constructed a model based on PAGE4 and lymph node metastasis to predict liver metastasis of CRC.

    Peanut-allergic children might be at risk for reactions to other legumes. However, it is not always possible to perform multiple oral food challenges in children. On the basis of patient case history, in vitro diagnostic tests, and eventually food challenges, we aimed at developing an algorithm...... for risk assessment of possible clinical reactions to other legumes (soybean, lupine, fresh, and blanched green pea). Seventy-five consecutive patients with a positive oral food challenge to peanut were included in the study. All tests were run as part of the routine allergy examination. A high proportion...... of patients and/or caretakers refused the administered legume oral food challenges. Obtained diagnoses from histamine release did not correlate significantly to the outcome of the algorithm. Interestingly, threshold from peanut challenges did not correlate with the risk assessment.The algorithm presented...

  1. Hepatitis B vaccine antibody response and the risk of clinical AIDS or death.

    Michael L Landrum

    Full Text Available BACKGROUND: Whether seroresponse to a vaccine such as hepatitis B virus (HBV vaccine can provide a measure of the functional immune status of HIV-infected persons is unknown.This study evaluated the relationship between HBV vaccine seroresponses and progression to clinical AIDS or death. METHODS AND FINDINGS: From a large HIV cohort, we evaluated those who received HBV vaccine only after HIV diagnosis and had anti-HBs determination 1-12 months after the last vaccine dose. Non-response and positive response were defined as anti-HBs <10 and ≥ 10 IU/L, respectively. Participants were followed from date of last vaccination to clinical AIDS, death, or last visit. Univariate and multivariable risk of progression to clinical AIDS or death were evaluated with Cox regression models. A total of 795 participants vaccinated from 1986-2010 were included, of which 41% were responders. During 3,872 person-years of observation, 122 AIDS or death events occurred (53% after 1995. Twenty-two percent of non-responders experienced clinical AIDS or death compared with 5% of responders (p<0.001. Non-response to HBV vaccine was associated with a greater than 2-fold increased risk of clinical AIDS or death (HR 2.47; 95% CI, 1.38-4.43 compared with a positive response, after adjusting for CD4 count, HIV viral load, HAART use, and delayed type hypersensitivity skin test responses (an in vivo marker of cell-mediated immunity. This association remained evident among those with CD4 count ≥ 500 cells/mm³ (HR 3.40; 95% CI, 1.39-8.32. CONCLUSIONS: HBV vaccine responses may have utility in assessing functional immune status and risk stratificating HIV-infected individuals, including those with CD4 count ≥ 500 cells/mm³.

    2016-07-01

    Full Text Available AIM To study the clinical profile of coronary artery disease in women and to identify the influence of the risk factors. METHODS We conducted a prospective observational study in Vydehi Institute of Medical Science and Research Centre (VIMS & RC, Bengaluru during the period June 2012 to Dec 2013. Patients admitted with history suggestive of coronary artery disease were evaluated clinically and investigated for risk factors. Prognosis with regards to morbidity and mortality following the standard treatment protocol was documented. RESULTS Out of 100 cases of coronary artery disease (CAD, 32 had Acute Myocardial infarction (AMI, 23 with Unstable Angina and 45 patients had Stable Angina. Nearly half of the patients had the traditional risk factors, namely hypertension (HTN, diabetes mellitus (DM, hyperlipidaemia and obesity. Chest pain was the most common symptom. Mortality was 14% which was observed predominantly in post-menopausal women who presented after 24 hours of the onset of symptoms. CONCLUSION Coronary artery disease is no longer a disease of men. Men and women share the same traditional risk factors like HTN, DM, Obesity, and Hyperlipidaemia. Increased incidence of complications and mortality occurred in those who presented after 24 hours of the symptoms. Our study highlights the importance of early recognition of CAD and initiation of thrombolytic therapy, to reduce significant morbidity and mortality.

  3. Risks to the fetus from diagnostic imaging during pregnancy: review and proposal of a clinical protocol

    Gomes, Mafalda; Matias, Alexandra [University of Porto, Faculty of Medicine, Porto (Portugal); Macedo, Filipe [SMIC, Porto (Portugal)

    2015-12-15

    Every day, medical practitioners face the dilemma of exposing pregnant or possibly pregnant patients to radiation from diagnostic examinations. Both doctors and patients often have questions about the risks of radiation. The most vulnerable period is between the 8th and 15th weeks of gestation. Deterministic effects like pregnancy loss, congenital malformations, growth retardation and neurobehavioral abnormalities have threshold doses above 100-200 mGy. The risk is considered negligible at 50 mGy and in reality no diagnostic examination exceeds this limit. The risk of carcinogenesis is slightly higher than in the general population. Intravenous iodinated contrast is discouraged, except in highly selected patients. Considering all the possible noxious effects of radiation exposure, measures to diminish radiation are essential and affect the fetal outcome. Nonionizing procedures should be considered whenever possible and every radiology center should have its own data analysis on fetal radiation exposure. In this review, we analyze existing literature on fetal risks due to radiation exposure, producing a clinical protocol to guide safe radiation use in a clinical setting. (orig.)

    Full Text Available Micha T Maeder,1 Otto D Schoch,2 Hans Rickli1 1Department of Cardiology, 2Department of Respiratory Medicine, Kantonsspital St Gallen, St Gallen, Switzerland Abstract: Obstructive sleep apnea (OSA is associated with cardiovascular risk factors, cardiovascular diseases, and increased mortality. Epidemiological studies have established these associations, and there are now numerous experimental and clinical studies which have provided information on the possible underlying mechanisms. Mechanistic proof-of-concept studies with surrogate endpoints have been performed to demonstrate that treatment of OSA by continuous positive airway pressure (CPAP has the potential to reverse or at least to attenuate not only OSA but also the adverse cardiovascular effects associated with OSA. However, no randomized studies have been performed to demonstrate that treatment of OSA by CPAP improves clinical outcomes in patients with cardiovascular risk factors and/or established cardiovascular disease and concomitant OSA. In the present review, we summarize the current knowledge on the role of OSA as a potential cardiovascular risk factor, the impact of OSA on cardiac function, the role of OSA as a modifier of the course of cardiovascular diseases such as coronary artery disease, atrial fibrillation, and heart failure, and the insights from studies evaluating the impact of CPAP therapy on the cardiovascular features associated with OSA.

    2014-01-01

    Full Text Available Patients with a low bone mineral density have an increased risk of cardiovascular diseases (CVD and venous thromboembolic events (VTE. The aim of our retrospective chart review was to investigate the prevalence of CVD, VTE, hypertension (HT, and diabetes mellitus type 2 (DM2 in patients with a recent clinical fracture visiting the Fracture Liaison Service (FLS. Out of 3057 patients aged 50–90 years, 1359 consecutive patients, who agreed and were able to visit the FLS for fracture risk evaluation, were included (71.7% women; mean age 65.2 yrs. Based on medical history, 29.9% had a history of CVD (13.7%, VTE (1.7%, HT (14.9%, and DM2 (7.1% or a combination. Their prevalence increased with age (21% in patients aged 50–59 years to 48% in patients aged >80 years and was higher in men than in women (36% versus 27%, but independent of bone mineral density and fracture type. Careful evaluation of medical history with respect to these risk factors should be performed in patients with a recent clinical fracture before starting treatment with medications that increase the risk of VTE or cardiovascular events, such as raloxifene, strontium ranelate, or NSAIDs.

    Full Text Available Prostate cancer (PCa is a very heterogeneous disease with respect to clinical outcome. This study explored differential DNA methylation in a priori selected genes to diagnose PCa and predict clinical failure (CF in high-risk patients.A quantitative multiplex, methylation-specific PCR assay was developed to assess promoter methylation of the APC, CCND2, GSTP1, PTGS2 and RARB genes in formalin-fixed, paraffin-embedded tissue samples from 42 patients with benign prostatic hyperplasia and radical prostatectomy specimens of patients with high-risk PCa, encompassing training and validation cohorts of 147 and 71 patients, respectively. Log-rank tests, univariate and multivariate Cox models were used to investigate the prognostic value of the DNA methylation.Hypermethylation of APC, CCND2, GSTP1, PTGS2 and RARB was highly cancer-specific. However, only GSTP1 methylation was significantly associated with CF in both independent high-risk PCa cohorts. Importantly, trichotomization into low, moderate and high GSTP1 methylation level subgroups was highly predictive for CF. Patients with either a low or high GSTP1 methylation level, as compared to the moderate methylation groups, were at a higher risk for CF in both the training (Hazard ratio [HR], 3.65; 95% CI, 1.65 to 8.07 and validation sets (HR, 4.27; 95% CI, 1.03 to 17.72 as well as in the combined cohort (HR, 2.74; 95% CI, 1.42 to 5.27 in multivariate analysis.Classification of primary high-risk tumors into three subtypes based on DNA methylation can be combined with clinico-pathological parameters for a more informative risk-stratification of these PCa patients.

  7. Identifying Adult Dengue Patients at Low Risk for Clinically Significant Bleeding.

    Joshua G X Wong

    Full Text Available Clinically significant bleeding is important for subsequent optimal case management in dengue patients, but most studies have focused on dengue severity as an outcome. Our study objective was to identify differences in admission parameters between patients who developed clinically significant bleeding and those that did not. We sought to develop a model for discriminating between these patients.We conducted a retrospective study of 4,383 adults aged >18 years who were hospitalized with dengue infection at Tan Tock Seng Hospital, Singapore from 2005 to 2008. Patients were divided into those with clinically significant bleeding (n = 188, and those without (n = 4,195. Demographic, clinical, and laboratory variables on admission were compared between groups to determine factors associated with clinically significant bleeding during hospitalization.On admission, female gender (p38°C (p38°C (aOR 1.81; 95% CI: 1.27-2.61, nausea/vomiting (aOR 1.39; 95% CI: 0.94-2.12, ANC (aOR 1.3; 95% CI: 1.15-1.46, ALC (aOR 0.4; 95% CI: 0.25-0.64, hematocrit percentage (aOR 0.96; 95% CI: 0.92-1.002 and platelet count (aOR 0.993; 95% CI: 0.988-0.998. At the cutoff of -3.919, the model achieved an AUC of 0.758 (sensitivity:0.87, specificity: 0.38, PPV: 0.06, NPV: 0.98.Clinical risk factors associated with clinically significant bleeding were identified. This model may be useful to complement clinical judgement in triaging adult dengue patients given the dynamic nature of acute dengue, particularly in pre-identifying those less likely to develop clinically significant bleeding.

    Risk factors for outbreaks in 1999 of clinical Salmonella enterica subsp. enterica serovar Typhimurium infection on dairy farms were studied in a matched case-control study with 47 case farms and 47 control farms. All 47 case farms experienced a clinical outbreak of salmonellosis which was confirmed with a positive bacteriologic culture for serovar Typhimurium in one or more samples. Serovar Typhimurium phage type 401 and 506 (definitive type 104, DT104) were the most frequently isolated phage types (13 isolates). On most farms (66%), clinical signs were seen only among adult cows. The most frequently reported clinical signs were diarrhoea (in 92% of the farms) and depression (in 79% of the farms). Control farms were matched on region and had no history of salmonellosis. A questionnaire was used to collect data on case and control farms. The relationship between serovar Typhimurium status of the farm and possible risk factors was tested using conditional logistic regression. Significant factors in the final model were presence of cats on the farm (OR=0.06), purchase of manure (OR=21.5), feeding colostrum only from own dam (OR=0.08), a non-seasonal calving pattern (OR=25), unrestricted grazing of lactating cows (OR=0.07), and a high mean mowing percentage of pasture (OR=1.02).

  9. Clinical risk factors associated with anti-epileptic drug responsiveness in canine epilepsy.

    Rowena M A Packer

    Full Text Available The nature and occurrence of remission, and conversely, pharmacoresistance following epilepsy treatment is still not fully understood in human or veterinary medicine. As such, predicting which patients will have good or poor treatment outcomes is imprecise, impeding patient management. In the present study, we use a naturally occurring animal model of pharmacoresistant epilepsy to investigate clinical risk factors associated with treatment outcome. Dogs with idiopathic epilepsy, for which no underlying cause was identified, were treated at a canine epilepsy clinic and monitored following discharge from a small animal referral hospital. Clinical data was gained via standardised owner questionnaires and longitudinal follow up data was gained via telephone interview with the dogs' owners. At follow up, 14% of treated dogs were in seizure-free remission. Dogs that did not achieve remission were more likely to be male, and to have previously experienced cluster seizures. Seizure frequency or the total number of seizures prior to treatment were not significant predictors of pharmacoresistance, demonstrating that seizure density, that is, the temporal pattern of seizure activity, is a more influential predictor of pharmacoresistance. These results are in line with clinical studies of human epilepsy, and experimental rodent models of epilepsy, that patients experiencing episodes of high seizure density (cluster seizures, not just a high seizure frequency pre-treatment, are at an increased risk of drug-refractoriness. These data provide further evidence that the dog could be a useful naturally occurring epilepsy model in the study of pharmacoresistant epilepsy.

    Cardiovascular disease (CVD) is the leading cause of mortality and a major cause of morbidity. Coronary heart disease (CHD) accounts for nearly half of all CVD deaths. Currently estimation of risk in primary prevention is based on the Framingham risk equations, which inputs traditional risk factors and is helpful in predicting the development of CHD in asymptomatic individuals. However many individuals suffer events in the absence of established risk factors for atherosclerosis and broad based population risk estimations may have little precision when applied to a given individual. To meet the challenge of CHD risk assessment, several tools have been developed to identify atherosclerotic disease in its preclinical stages. This paper aims to incorporate information from coronary artery calcification (CAC) scoring from a computed tomographic "heartscan" (using Electron Beam Tomography (EBT) as the validated prototype) along with current Framingham risk profiling in order to refine risk on an absolute scale by combining imaging and clinical data to affect a more comprehensive calculation of absolute risk in a given individual. For CAC scores above the 75th percentile but or =55 years, women> or =65 years) a CAC = 0 will result in an age point score corresponding to the age-group whose median CAC score is zero i.e., 40-44 years for men and 55-59 years for women. The utilization of CAC scores allows the inclusion of sub-clinical disease definition into the context of modifiable risk factors as well as identifies high-risk individuals requiring aggressive treatment.

  11. Weighing the evidence: risks and benefits of participatory documentary in corporatized clinics.

    Hansen, Helena

    2013-12-01

    This paper describes the effects of one U.S.-based public psychiatry clinic's shift to a centralized, corporate style of management, in response to pressures to cut expenditures by focusing on "evidence based" treatments. Participant observation research conducted between 2008 and 2012 for a larger study involving 127 interviews with policy makers, clinic managers, clinical practitioners and patients revealed that the shift heralded the decline of arts based therapies in the clinic, and of the social networks that had developed around them. It also inspired a participatory video self-documentary project among art group members, to portray the importance of arts-based therapies and garner public support for such therapies. Group members found a way to take action in the face of unilateral decision making, but experienced subsequent restrictions on clinic activities and discharge of core members from the clinic. The paper ends with a discussion of biopolitics, central legibility through corporate standardization, and the potential and risks of participatory documentaries to resist these trends.

    AIM: To comprehend the risk factors of recurrence of hepatocellular carcinoma (HCC) and its relationship with the infection patterns of hepatitis B virus (HBV). METHODS: All materials of 270 cases of postoperative HCC were statistically analyzed by SPSS software. Recurrence and metastasis were classified into early (≤2 years) and late phase (>2 years). Risk factors for recurrence and metastasis after surgery in each group were analyzed.RESULTS: Out of 270 cases of HCC, 162 cases were followed up in which recurrence and metastasis occurred in 136 cases. There were a lot of risk factors related to recurrence and metastasis of HCC; risk factors contributing to early phase recurrence were serum AFP level, vascular invasion, incisal margin and operative transfusion, gross tumor classification and number of intrahepatic node to late phase recurrence. The HBV infective rate of recurrent HCC was 94.1%, in which "HBsAg, HBeAb, HBcAb" positive pattern reached 45.6%. The proportion of HBV infection in solitary large hepatocellular carcinoma (SLHCC) evidently decreased compared to nodular hepatocellular carcinoma (NHCC) (P<0.05).CONCLUSION: The early and late recurrence and metastasis after hepatectomy of HCC were associated with different risk factors. The early recurrence may be mediated by vascular invasion and remnant lesion, the late recurrence by tumor's clinical pathology propert, as multicentric carcinogenesis or intrahepatic carcinoma denovo. HBV replication takes a great role in this process. From this study, we found that SLHCC has more satisfactory neoplasm biological behavior than NHCC.

  13. Clinical features and risk factors for atazanavir (ATV-associated urolithiasis: a case-control study.

    Matthieu Lafaurie

    Full Text Available OBJECTIVES: Clinical features and risk factors for atazanavir (ATV-associated urolithiasis have not been fully investigated. METHODS: We reviewed all cases of ATV-containing urolithiasis identified by infrared spectrophotometry among HIV-infected patients over a 5-year period to describe their clinical features and outcome. A case-control study was performed to identify risk factors associated with ATV-associated urolithiasis using univariate and multivariate logistic regression analyses. RESULTS: 30 cases of ATV-associated urolithiasis were analyzed. Patients were mostly men (87%, median age: 45.5 years, median CD4 cell count: 443 cells/µL and 97% had plasma HIV RNA level <50 cp/mL. Median time between the initiation of ATV-containing regimen and the diagnosis of urolithiasis was 3.1 years. Patients presented with flank pain in 90% and macroscopic hematuria in 82.6%, 34% had renal dysfunction and 44.8% needed ureteroscopic treatment. In univariate analysis, chronic hepatitis C, a history of urolithiasis, prior use of indinavir, ATV duration, undetectable plasma HIV RNA, use of ritonavir as a booster and serum free bilirubin level were associated with ATV-urolithiasis. Multivariate models retained serum free bilirubin level (OR: 2.31, p<0.02 and either ATV duration (OR:  = 1.42, p = <0.03 or a history of urolithiasis (OR = 4.79, p<0.02 when adjusting on serum free bilirubin level as risk factors associated with urolithiasis. CONCLUSIONS: ATV-containing urolithiasis are associated with frank clinical symptoms and may require surgical intervention. A high serum bilirubin level, a long exposure to ATV and a history of urolithiasis are risk factors for this rare adverse event.

    2015-04-01

    Full Text Available Objective: To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. Methods: This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Results: Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55% men and 9 (45% women. Nine (45% patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85% patients and 3 (15% were managed conservatively. Conclusion: End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who

    2015-01-01

    Full Text Available Bladder cancer occurs in the epithelial lining of the urinary bladder and is amongst the most common types of cancer in humans, killing thousands of people a year. This paper is based on the hypothesis that the use of clinical and histopathological data together with information about the concentration of various molecular markers in patients is useful for the prediction of outcomes and the design of treatments of nonmuscle invasive bladder carcinoma (NMIBC. A population of 45 patients with a new diagnosis of NMIBC was selected. Patients with benign prostatic hyperplasia (BPH, muscle invasive bladder carcinoma (MIBC, carcinoma in situ (CIS, and NMIBC recurrent tumors were not included due to their different clinical behavior. Clinical history was obtained by means of anamnesis and physical examination, and preoperative imaging and urine cytology were carried out for all patients. Then, patients underwent conventional transurethral resection (TURBT and some proteomic analyses quantified the biomarkers (p53, neu, and EGFR. A postoperative follow-up was performed to detect relapse and progression. Clusterings were performed to find groups with clinical, molecular markers, histopathological prognostic factors, and statistics about recurrence, progression, and overall survival of patients with NMIBC. Four groups were found according to tumor sizes, risk of relapse or progression, and biological behavior. Outlier patients were also detected and categorized according to their clinical characters and biological behavior.

    ABSTRACT Objective: to correlate classification in risk categories with the clinical profiles, outcomes and origins of patients. Method: analytical cross-sectional study conducted with 697 medical forms of adult patients. The variables included: age, sex, origin, signs and symptoms, exams, personal antecedents, classification in risk categories, medical specialties, and outcome. The Chi-square and likelihood ratio tests were used to associate classifications in risk categories with origin, signs and symptoms, exams, personal antecedents, medical specialty, and outcome. Results: most patients were women with an average age of 44.5 years. Pain and dyspnea were the symptoms most frequently reported while hypertension and diabetes mellitus were the most common comorbidities. Classifications in the green and yellow categories were the most frequent and hospital discharge the most common outcome. Patients classified in the red category presented the highest percentage of ambulance origin due to surgical reasons. Those classified in the orange and red categories also presented the highest percentage of hospitalization and death. Conclusion: correlation between clinical aspects and outcomes indicate there is a relationship between the complexity of components in the categories with greater severity, evidenced by the highest percentage of hospitalization and death.

  19. Mining heart disease risk factors in clinical text with named entity recognition and distributional semantic models.

    Urbain, Jay

    2015-12-01

    We present the design, and analyze the performance of a multi-stage natural language processing system employing named entity recognition, Bayesian statistics, and rule logic to identify and characterize heart disease risk factor events in diabetic patients over time. The system was originally developed for the 2014 i2b2 Challenges in Natural Language in Clinical Data. The system's strengths included a high level of accuracy for identifying named entities associated with heart disease risk factor events. The system's primary weakness was due to inaccuracies when characterizing the attributes of some events. For example, determining the relative time of an event with respect to the record date, whether an event is attributable to the patient's history or the patient's family history, and differentiating between current and prior smoking status. We believe these inaccuracies were due in large part to the lack of an effective approach for integrating context into our event detection model. To address these inaccuracies, we explore the addition of a distributional semantic model for characterizing contextual evidence of heart disease risk factor events. Using this semantic model, we raise our initial 2014 i2b2 Challenges in Natural Language of Clinical data F1 score of 0.838 to 0.890 and increased precision by 10.3% without use of any lexicons that might bias our results.

  20. Characterization of Clinical and Genetic Risk Factors Associated with Dyslipidemia after Kidney Transplantation

    2015-01-01

    Full Text Available We determined the prevalence of dyslipidemia in a Japanese cohort of renal allograft recipients and investigated clinical and genetic characteristics associated with having the disease. In total, 126 patients that received renal allograft transplants between February 2002 and August 2011 were studied, of which 44 recipients (34.9% were diagnosed with dyslipidemia at 1 year after transplantation. Three clinical factors were associated with a risk of having dyslipidemia: a higher prevalence of disease observed among female than male patients P=0.021 and treatment with high mycophenolate mofetil P=0.012 and prednisolone P=0.023 doses per body weight at 28 days after transplantation. The genetic association between dyslipidemia and 60 previously described genetic polymorphisms in 38 putative disease-associated genes was analyzed. The frequency of dyslipidemia was significantly higher in patients with the glucocorticoid receptor (NR3C1 Bcl1 G allele than in those with the CC genotype P=0.001. A multivariate analysis revealed that the NR3C1 Bcl1 G allele was a significant risk factor for the prevalence of dyslipidemia (odds ratio = 4.6; 95% confidence interval = 1.8–12.2. These findings may aid in predicting a patient’s risk of developing dyslipidemia.

  1. Predicting the risk of suicide by analyzing the text of clinical notes.

    Chris Poulin

    Full Text Available We developed linguistics-driven prediction models to estimate the risk of suicide. These models were generated from unstructured clinical notes taken from a national sample of U.S. Veterans Administration (VA medical records. We created three matched cohorts: veterans who committed suicide, veterans who used mental health services and did not commit suicide, and veterans who did not use mental health services and did not commit suicide during the observation period (n = 70 in each group. From the clinical notes, we generated datasets of single keywords and multi-word phrases, and constructed prediction models using a machine-learning algorithm based on a genetic programming framework. The resulting inference accuracy was consistently 65% or more. Our data therefore suggests that computerized text analytics can be applied to unstructured medical records to estimate the risk of suicide. The resulting system could allow clinicians to potentially screen seemingly healthy patients at the primary care level, and to continuously evaluate the suicide risk among psychiatric patients.

  2. Identification of patients at low risk of dying after acute myocardial infarction, by simple clinical and submaximal exercise test criteria.

    1988-09-01

    A consecutive series of 559 hospital survivors of acute myocardial infarction aged less than 66 years were studied; 93 were designated prospectively as low-risk because they were suitable for early submaximal exercise testing and had none of the following clinical or exercise test 'risk factors': (1) angina for at least one month prior to infarction; (2) symptomatic ventricular arrhythmias, or (3) recurrent ischaemic pain, both after the first 24 h of infarction; (4) cardiac failure; (5) cardiomegaly; and (6) an abnormal exercise test (angina, ST-depression or poor blood pressure response). Altogether 301 patients were exercised; their mortality over a median follow-up of 2.4 years was 10.2%, versus 24.6% in the 258 patients not exercised (P = 0.0005). Absence of clinical 'risk factors' alone, in the exercised patients, identified 156 with a mortality of 5.4% versus 15.6% in the 145 with at least one clinical 'risk factor' (P = 0.004). The fully defined low-risk group comprised 93 of the former patients who had neither clinical nor exercise test 'risk factors'. None of these patients died compared with 19 of those with at least one 'risk factor' (mortality = 14.7%; P = 0.002). Their respective rates of non-fatal reinfarction were similar and never exceeded 5% per annum. Therefore, simple clinical and exercise test criteria can positively identify low-risk patients after infarction in whom secondary prevention may be inappropriate.

    It is known that clinic blood pressure (BP), gender, cigarette smoking, dyslipidemia, anemia and thiazolidenediones (TZD) treatment are predictors for clinically significant diabetic macula edema (CSDME). We examined a most risky factor for CSDME in Japanese patients with type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR) confirmed using optical coherence tomography by multiple regression analysis (MRA). As the risk factors, wakening-up BP was added to such factors. Seven diabetic Japanese patients with CSDME (group 1) and 124 subjects without CSDME (group 2) assonated with DR using optical coherence tomography were studied. The durations of T2DM in groups 1 and 2 were 15±10 years and 20±15 years, respectively. There was no statistically difference in means of gender, duration, age, body mass index (BMI), HbA1c, TC, LDL and TC/HDL, serum creatinine, urinary albumin excretion rate, and clinic BP between two groups. Morning systolic home BP (MSHBP), cigarette smoking and foveal thickness were significantly (ppioglitazone as TZD treatment were significantly positive predictors for CSDME, while BMI had a significantly negative predictor. Other variables were not significantly correlated to CSDME. The review summarizes a multiple regression analysis revealed that MSHBP makes an addition to predictive factors for CSDME among risk factors reported previously in patient with T2DM.

  4. Identification of occupational risk factors by interviewing injured workers in an out-patient clinic

    Full Text Available

    Background: To prevent injuries, identification of the involved risk factors is necessary. Two recent in-depth investigations were carried out in the health service of Oslo on workers seeking treatment of severe occupational injuries. The interviews were rather time-consuming, and hence rather costly. The aim of thepresent study was to find a less time-consuming method which nevertheless would identify preventable risk actors.

    Methods: In-depth investigations of 15 injuries with nail guns and 28 injuries related to scaffolding were onducted in an out-patient clinic in Trondheim, Norway. Patients were interviewed by health personnel just efore or after the treatment based on specifically designed questionnaires. A group of specialists analysed the information collected.

    Results: Some risk factors were identified: design weaknesses inherent in nail guns, presence of snow and ice at the injury location, foreign body in the eye and lack of control/inspection of scaffolding when erected. On average, about two man hours were used for each injury. The most relevant questions were those directly related to the narrative, in particular how the injury occurred, and if any special conditions were involved. Quite a few data elements require epidemiological representative studies in order to assess them as potential risk factors.

    Conclusions: This relatively low time-consuming method revealed some risk factors. However, it could be more effective if the interviews were conducted by telephone a few days after the treatment by a specialist in that particular injury type; such as an experienced labour inspector, in order to probe more deeply into the technical risk factors.

  5. Complex fibroadenoma and breast cancer risk: a Mayo Clinic Benign Breast Disease Cohort Study.

    The purpose of this study is to examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks. The study included women aged 18-85 years from the Mayo Clinic Benign Breast Disease Cohort who underwent excisional breast biopsy from 1967 through 1991. Within this cohort, women who had fibroadenoma were compared to women who did not have fibroadenoma. Breast cancer risk (observed versus expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression [nonproliferative disease, proliferative disease without atypia (PDWA), or atypical hyperplasia]. Fibroadenoma was identified in 2136 women [noncomplex, 1835 (85.9%); complex, 301 (14.1%)]. SIR for noncomplex fibroadenoma was 1.49 (95% CI 1.26-1.74); for complex fibroadenoma, it was 2.27 (95% CI 1.63-3.10) (test for heterogeneity in SIR, P = .02). However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer.

  7. Abstract bodies, concrete risks: clinical devices and the health of ova donors in Argentine reproductive medicine

    Lucía Ariza

    2016-10-01

    Full Text Available Using a methodological perspective grounded in science and technology studies, this article analyzes two sociotechnical devices used in Argentine reproductive medicine (biostatistical measures and donation registries with the aim of controlling both the so-called “genetic risk” arising from the use of donated ova as well as the health risks to female donors. By examining how the deployment of monitoring criteria disregards the specificity of ova donation, the article suggests that it is not the absence of control measures and clinical criteria that produces an inadequate monitoring of such risks, but rather the concrete ways in which such measures are implemented that results in potential harms to the health of female donors.

    2014-01-01

    Given dramatic racial disparities in rates of HIV/STDs among African Americans, understanding broader structural factors that increase the risk for HIV/STDs is crucial. This study investigated incarceration history and unstable housing as two structural predictors of HIV risk behavior among 293 African Americans (159 men/134 women, Mage=27). Participants were recruited from an urban STD clinic in the southeastern U.S. Approximately half the sample had been incarcerated in their lifetime (54%), and 43% had been unstably housed in the past 6 months. Incarceration was independently associated with number of sex partners and the frequency of unprotected sex. Unstable housing was independently associated with the frequency of unprotected sex. However, these main effects were qualified by significant interactions: individuals with a history of incarceration and more unstable housing had more sex partners and more unprotected sex in the past three months than individuals without these structural barriers. Implications for structural-level interventions are discussed. PMID:24060677

    Pifferi, Antonio; Quarto, Giovanna; Abbate, Francesca; Balestreri, Nicola; Menna, Simona; Cassano, Enrico; Cubeddu, Rinaldo; Taroni, Paola

    2015-07-01

    A retrospective pilot clinical study on time domain multi-wavelength (635 to 1060 nm) optical mammography was exploited to assess collagen as a breast-cancer risk factor on a total of 109 subjects (53 healthy and 56 with malignant lesions). An increased cancer occurrence is observed on the 15% subset of patients with higher age-matched collagen content. Further, a similar clustering based on the percentage breast density leads to a different set of patients, possibly indicating collagen as a new independent breast cancer risk factor. If confirmed statistically and on larger numbers, these results could have huge impact on personalized diagnostics, health care systems, as well as on basic research.

  10. Muscle cramping in athletes--risk factors, clinical assessment, and management.

    Schwellnus, Martin P; Drew, Nichola; Collins, Malcolm

    2008-01-01

    Exercise associated muscle cramping (EAMC) is defined as a painful, spasmodic, and involuntary contraction of skeletal muscle that occurs during or immediately after exercise. There is a high lifetime prevalence of EAMC in athletes, specifically in endurance athletes. The most important risk factors for EAMC in athletes are a previous history of EAMC, and performing exercise at a higher relative exercise intensity or duration, when compared with normal training and participating in hot and humid environmental conditions. The diagnosis of EAMC is made clinically, and the most effective immediate management of EAMC is rest and passive stretching. The key to the prevention of EAMC is to reduce the risk of developing premature muscle fatigue.

  11. A single hospital study on portal vein thrombosis in cirrhotic patients - clinical characteristics & risk factors

    Huisong Chen

    2014-01-01

    Full Text Available Background & objectives: Discrepancies exist in the reported prevalence of portal vein thrombosis (PVT, and its clinical characteristics and sites of occurrence need to be elucidated. The risk factors for PVT are also poorly understood. This single centre study was undertaken to determine the clinical characteristics, sites of occurrence, and risk factors associated with PVT in patients with liver cirrhosis. Methods: Hospitalized cirrhotic patients (N = 162 were segregated into the PVT and non-PVT groups. Indices possibly associated with PVT were measured and PVT was detected by both Doppler ultrasonography and computed tomography portal angiography. The portal vein diameter and flow velocity and splenic thickness were measured by ultrasonography. Results: PVT was found in 40 patients (24.7%; in 34 PVT patients (85%, the liver cirrhosis resulted from hepatitis B virus infections. Most (90% patients were Child-Pugh classes B and C, with similar distribution between the groups. PVT was seen in 20 patients in the portal and superior mesenteric veins; ascites, abdominal pain, gastrointestinal bleeding, and jaundice were common findings in PVT patients. Haemoglobin levels and blood platelet counts (BPCs were significantly lower and splenic thickness was greater in PVT than in non-PVT patients (P<0.01. There was a significant positive correlation between BPCs and platelet aggregation rates (R = 0.533, P<0.01. Interpretation & conclusions: The occurrence of PVT was 24.7 per cent, primarily in post-hepatitis B liver cirrhosis patients. PVT occurred mainly in the portal vein trunk and superior mesenteric vein. Different PVT sites may account for the differing clinical presentations. The lower levels of haemoglobin and BPCs as well as splenic thickening were associated with PVT. Splenic thickening may be a risk factor for PVT.

  12. Influences of intermittent preventive treatment and persistent multiclonal Plasmodium falciparum infections on clinical malaria risk.

    Anne Liljander

    Full Text Available BACKGROUND: Intermittent preventive treatment (IPT of malaria involves administration of curative doses of antimalarials at specified time points to vulnerable populations in endemic areas, regardless whether a subject is known to be infected. The effect of this new intervention on the development and maintenance of protective immunity needs further understanding. We have investigated how seasonal IPT affects the genetic diversity of Plasmodium falciparum infections and the risk of subsequent clinical malaria. MATERIAL AND METHODS: The study included 2227 Ghanaian children (3-59 months who were given sulphadoxine-pyrimethamine (SP bimonthly, artesunate plus amodiaquine (AS+AQ monthly or bimonthly, or placebo monthly for six months spanning the malaria transmission season. Blood samples collected at three post-interventional surveys were analysed by genotyping of the polymorphic merozoite surface protein 2 gene. Malaria morbidity and anaemia was monitored during 12 months follow-up. RESULTS: Monthly IPT with AS+AQ resulted in a marked reduction in number of concurrent clones and only children parasite negative just after the intervention period developed clinical malaria during follow-up. In the placebo group, children without parasites as well as those infected with ≥2 clones had a reduced risk of subsequent malaria. The bimonthly SP or AS+AQ groups had similar number of clones as placebo after intervention; however, diversity and parasite negativity did not predict the risk of malaria. An interaction effect showed that multiclonal infections were only associated with protection in children without intermittent treatment. CONCLUSION: Molecular typing revealed effects of the intervention not detected by ordinary microscopy. Effective seasonal IPT temporarily reduced the prevalence and genetic diversity of P. falciparum infections. The reduced risk of malaria in children with multiclonal infections only seen in untreated children suggests that

  13. Radiation risk and protection of patients in clinical SPECT/CT

    Brix, Gunnar; Nekolla, Elke A.; Nosske, Dietmar [Federal Office for Radiation Protection, Department of Medical and Occupational Radiation Protection, Oberschleissheim (Germany); Borowski, Markus [Klinikum Braunschweig, Institute of Radiation Diagnostics and Nuclear Medicine, Braunschweig (Germany)

    Clinical studies have demonstrated that hybrid single photon emission computed tomography (SPECT)/CT for various diagnostic issues has an added value as compared to SPECT alone. However, the combined acquisition of functional and anatomical images can substantially increase radiation exposure to patients, in particular when using a hybrid system with diagnostic CT capabilities. It is, therefore, essential to carefully balance the diagnostic needs and radiation protection requirements. To this end, the evidence on health effects induced by ionizing radiation is outlined. In addition, the essential concepts for estimating radiation doses and lifetime attributable cancer risks associated with SPECT/CT examinations are presented taking into account both the new recommendations of the International Commission on Radiological Protection (ICRP) as well as the most recent radiation risk models. Representative values of effective dose and lifetime attributable risk are reported for ten frequently used SPECT radiopharmaceuticals and five fully diagnostic partial-body CT examinations. A diagnostic CT scan acquired as part of a combined SPECT/CT examination contributes considerably to, and for some applications even dominates, the total patient exposure. For the common SPECT and CT examinations considered in this study, the lifetime attributable risk of developing a radiation-related cancer is less than 0.27 %/0.37 % for men/women older than 16 years, respectively, and decreases markedly with increasing age at exposure. Since there is no clinical indication for a SPECT/CT examination unless an emission scan has been indicated, the issue on justification comes down to the question of whether it is necessary to additionally acquire a low-dose CT for attenuation correction and anatomical localization of tracer uptake or even a fully diagnostic CT. In any case, SPECT/CT studies have to be optimized, e.g. by adapting dose reduction measures from state-of-the-art CT practice, and

    The aim of the study was to describe a diagnostic protocol to lower the risk of a mycotic invasive infection among allotransplant recipients and to suggest the use of preoperative prophylaxis and/or empiric therapy. We chose a group of 268 allograft recipients with transient or constant yeast colonization or confirmed yeast infection. Among 7744 clinical samples, 475 were positive for fungi. We used conventional fungal laboratory diagnosis, enzymatic activity tests, serologic tests, molecular diagnosis of samples from sterile body sites, and histopathologic examinations. The following clinical samples were examined: blood samples; swabs from mouth lesions, throat, and rectum; and sputum, urine, and fecal samples from kidney transplant recipients and simultaneous pancreas-kidney transplantation recipients who are highly predisposed to mycotic infections. We established microbiologic criteria of a systemic mycosis and principles to distinguish colonization from infection.

  17. Omega-3 fatty acids and cardiovascular disease: effects on risk factors, molecular pathways, and clinical events.

    Mozaffarian, Dariush; Wu, Jason H Y

    2011-11-08

    We reviewed available evidence for cardiovascular effects of n-3 polyunsaturated fatty acid (PUFA) consumption, focusing on long chain (seafood) n-3 PUFA, including their principal dietary sources, effects on physiological risk factors, potential molecular pathways and bioactive metabolites, effects on specific clinical endpoints, and existing dietary guidelines. Major dietary sources include fatty fish and other seafood. n-3 PUFA consumption lowers plasma triglycerides, resting heart rate, and blood pressure and might also improve myocardial filling and efficiency, lower inflammation, and improve vascular function. Experimental studies demonstrate direct anti-arrhythmic effects, which have been challenging to document in humans. n-3 PUFA affect a myriad of molecular pathways, including alteration of physical and chemical properties of cellular membranes, direct interaction with and modulation of membrane channels and proteins, regulation of gene expression via nuclear receptors and transcription factors, changes in eicosanoid profiles, and conversion of n-3 PUFA to bioactive metabolites. In prospective observational studies and adequately powered randomized clinical trials, benefits of n-3 PUFA seem most consistent for coronary heart disease mortality and sudden cardiac death. Potential effects on other cardiovascular outcomes are less-well-established, including conflicting evidence from observational studies and/or randomized trials for effects on nonfatal myocardial infarction, ischemic stroke, atrial fibrillation, recurrent ventricular arrhythmias, and heart failure. Research gaps include the relative importance of different physiological and molecular mechanisms, precise dose-responses of physiological and clinical effects, whether fish oil provides all the benefits of fish consumption, and clinical effects of plant-derived n-3 PUFA. Overall, current data provide strong concordant evidence that n-3 PUFA are bioactive compounds that reduce risk of cardiac

Driven by new genetic technologies and advances in molecular medicine, there has recently been concrete progress in understanding some of the specific genetic causes of this serious psychiatric illness. In particular, several large rare structural variants have been convincingly associated with schizophrenia, in targeted studies over two decades with respect to 22q11.2 microdeletions, and more recently in large-scale, genome-wide case-control studies. These advances promise to help many families afflicted with this disease. In this review, we critically appraise recent developments in the field of schizophrenia genetics through the lens of immediate clinical applicability. Much work remains in translating the recent surge of genetic research discoveries into the clinic. The epidemiology and basic genetic parameters (such as penetrance and expression of most genomic disorders associated with schizophrenia are not yet well characterized. To date, 22q11.2 deletion syndrome is the only established genetic subtype of schizophrenia of proven clinical relevance. We use this well-established association as a model to chart the pathway for translating emerging genetic discoveries into clinical practice. We also propose new directions for research involving general genetic risk prediction and counseling in schizophrenia.Keywords: schizophrenia, genetics, 22q11 deletion syndrome, copy number variation, genetic counseling, genetic predisposition to disease

    We present the final results of a study using the IRDI (Clinical Risk Indicators in Child Development). Based on a psychoanalytic approach, 31 risk signs for child development were constructed and applied to 726 children between the ages of 0 and 18 months. One sub-sample was evaluated at the age of three. The results showed a predictive capacity of IRDIs to indicate developmental problems; 15 indicators for the IRDI were also highlighted that predict psychic risk for the constitution of the ...

    1996-01-01

    Positive blood cultures in very low birthweight or preterm infants usually reflect bacteraemia, septicaemia, or failure of asepsis during sampling and lead to increased costs and length of stay. Rates of nosocomial, or hospital acquired, bacteraemia may therefore be important indicators of neonatal unit performance, if comparisons are adjusted for differences in initial risk. In a preliminary study the risk of nosocomial bacteraemia was related to initial clinical risk and illness severity me...

  1. Clinical Features and Risk Factors of Patients with Presumed Ocular Toxoplasmosis

    Fuh, Ukamaka Celestina; Omoti, Afekhide E.; Enock, Malachi E.

    2016-01-01

    Purpose: To determine the clinical features and risk factors of presumed ocular toxoplasmosis (POT) in patients affected with the condition at Irrua, Nigeria. Methods: The study included 69 patients with POT, and 69 age and sex matched subjects who served as the control group. Data was obtained using interviewer administered questionnaires. Examination included measurement of visual acuity (VA), intraocular pressure (IOP), slit lamp examination, gonioscopy and dilated fundus examination. Results: Mean age of cases and control subjects was 57.16 ± 18.69 and 56.09 ± 16.01 years respectively. The peak age group in patients with POT was 60 years and above. The most common presenting complaint was blurred vision occurring in 100% of cases. Drinking unfiltered water in 58 (84.1%) patients was the most common risk factor. Other risk factors included post cataract surgery status in 32 (46.4%) subjects, ingestion of poorly cooked meat in 30 (43.5%) cases and exposure to cats in 9 (13.0%) patients. All risk factors were more common in POT patients (P < 0.05). Out of 69 patients, 62 (89.9%) had unilateral while 7 (10.1%) had bilateral involvement. Out of 76 eyes with uveitis, 53 (69.7%) were blind. Active disease was significantly more common with increasing age (P < 0.05). Conclusion: Patients with POT were rather old and some risk factors were modifiable, therefore health education for preventing the transmission of toxoplasmosis and provision of sanitary water may help reduce the incidence of ocular toxoplasmosis.

  3. Employing New Mathematical Models and Equations to Evaluate Risk-Benefit Criteria of Clinical Therapeutics

    Da Y. Lu

    2007-01-01

    Full Text Available Current preclinical and clinical evaluation of a drugs or therapy is at first to find out a maximum toxicity tolerance, which is overall fixed. The potential therapeutic dosage will be ranged just lower or within the periphery of these maximum tolerant data. A hidden acceptance among general researchers lies as the toxicity concentration of a drug is always the same and can be referred as a fixed data. However, practical therapeutics is not very strictly following this doctrine. Even using many strict well-formed mathematical models and toxicity evaluating systems, the disputes and lawsuits of some newly-developed drugs are increasing dramatically nowadays. In this work, a mathematical equation and a dynamic parameter  are generated to help improving this situation. This new mathematic model combines and integrates effective, toxicity and no effective data as a whole, which fits to evaluate the risk-benefits of therapeutics in dynamic and changeable states. We need no more to deduce therapeutic dosage from fixed tolerance data regardless different therapeutic modes of action and toxicity of drugs acting on different organs and physiological systems. We hypothesize and equation that risk-benefit ratios are varied with drug dosages. It is a new start to help the understanding of effects and toxicities of therapeutic same time in a single clinical practice and well compliment with previous mathematical models.

  4. Clinical responsibility, accountability, and risk aversion in mental health nursing: a descriptive, qualitative study.

    Manuel, Jenni; Crowe, Marie

    2014-08-01

    A number of recent, highly-publicized, perceived health-care service failures have raised concerns about health professionals' accountabilities. Relevant to these concerns, the present study sought to examine how mental health nurses understood clinical responsibility and its impact on their practice. A descriptive, qualitative design was used, and a convenience sample of 10 mental health nurses was recruited from specialist inpatient and outpatient mental health settings in Canterbury, New Zealand. Data were collected using semistructured interviews, and the transcriptions were analysed using an inductive, descriptive approach. Three major themes were identified: being accountable, fostering patient responsibility, and shifting responsibility. Being accountable involved weighing up patients' therapeutic needs against the potential for blame in an organizational culture of risk management. Fostering patient responsibility described the process of deciding in what situations patients could take responsibility for their behaviour. Shifting responsibility described the culture of defensive practice fostered by the organizational culture of risk aversion. The present study highlighted the challenges mental health nurses experience in relation to clinical responsibility in practice, including the balancing required between the needs of patients, the needs of the organization, and the perceived need for self-protection.

  5. Cyclosporin A acute encephalopathy and seizure syndrome in childhood: clinical features and risk of seizure recurrence.

    Gleeson, J G; duPlessis, A J; Barnes, P D; Riviello, J J

    1998-07-01

    Cyclosporin A is associated with an acute encephalopathy including seizures and alterations in mental status, herein referred to as cyclosporin A acute encephalopathy and seizure syndrome. The clinical history, electroencephalogram (EEG), and neuroimaging findings in 19 children with cyclosporin A acute encephalopathy and seizure syndrome over a 10-year period were reviewed in order to delineate clinical characteristics, imaging features, and to determine the risk of seizure recurrence in this population. All 19 had motor seizures associated with other features of cortical and subcortical dysfunction. The acute mean cyclosporin A level was 342 microg/L, but was within the "therapeutic" range in five cases. Brain imaging by computed tomography (CT) or magnetic resonance imaging (MRI) in the acute or subacute phase revealed lesions characteristic of cyclosporin A toxicity in 14 cases. Acute EEG abnormalities were present in all and included epileptiform discharges or focal slowing. Patients were followed for a median of 49 months (1-9 years). Follow-up imaging (n = 10) showed lesion resolution or improvement in the majority while EEG (n = 10) had normalized in only three. Seizures recurred in six patients and only in those with persistent EEG or imaging abnormalities. No patient had a second episode of cyclosporin A associated neurotoxicity or seizure. It appears that a significant risk of seizure recurrence exists following cyclosporin A acute encephalopathy and seizure syndrome and primarily in those children with persistent EEG or imaging abnormalities.

    2014-09-13

    The aim of this retrospective study was to assess prevalence, risk factors, clinical presentation and outcome of phenobarbitone induced haematological abnormalities (PBIHA) in dogs. The medical records of two veterinary referral institutions were searched for dogs diagnosed with idiopathic epilepsy and treated with PB as monotherapy or polytherapy between March 2003 and September 2010. Sixteen dogs had PBIHA; the median age at diagnosis was 69.5 months. Phenobarbitone was administered at a median dose of 3 mg/kg twice a day for a median period of 100.5 days and the median serum phenobarbitone level was 19 μg/ml. Two dogs had neutropenia, three had anaemia and thrombocytopenia, two had anaemia and neutropenia; the remaining nine had pancytopenia. All dogs were referred for non-specific clinical signs. Phenobarbitone was discontinued after diagnosis, and the median time to resolution of PBIHA was 17 days. The prevalence and risk factors for PBIHA were evaluated from a questionnaire survey of referring practices to obtain more detailed follow-up on cases diagnosed with idiopathic epilepsy. The prevalence rate of PBIHA was 4.2%, and the condition occurred in dogs treated with standard therapeutic doses often within the first three months after starting treatment. Serial haematological evaluations should be therefore considered from the beginning of phenobarbitone therapy to allow early diagnosis and treatment of PBIHA.

  7. Strongyloidiasis: prevalence, risk factors, clinical and laboratory features among diarrhea patients in Ibadan Nigeria.

    Dada-Adegbola, H O; Oluwatoba, O A; Bakare, R A

    2010-12-01

    Strongyloidiasis is a parasitic infection caused by Strongyloides stercoralis. The infection is usually mild or asymptomatic in normal immunocompetent individuals, but could be very severe or even fatal due to hyper infection in individuals who are immunosuppressed. This study aimed at determining the prevalence, risk factors and features of strongyloidiasis among diarrhea patients in Ibadan. This is a descriptive cross-sectional study of diarrhea patients from a teaching hospital, three major government hospitals and one mission hospital in Ibadan. Self administered questionnaire, clinical assessment and laboratory investigations were used to confirm health status and presence of S. stercoralis. Diagnosis was made by microscopic examination of stool in saline preparation and formol-ether concentration. One thousand and ninety patients, (562 (51.6%) males and 528 (48.4%) females) consisting 380 (34.9%) children and 710 (65.1%) adults who had diarrhea were studied. The prevalence rate for the parasite among diarrhea patients was 3.0%. While the risk factor for infection remains contact with contaminated soil, malnutrition, steroid therapy, HIV/AIDS, lymphomas, tuberculosis, and chronic renal failure. Others are maleness, institutionalism and alcoholism. Predominant clinical presentations are abdominal pain, chronic diarrhea, and bloating and weight loss, Strongyloides stercoralis should be considered in diarrhea patients who are either malnourished or immunosuppressed.

    Background:Current knowledge about clinical and genetic risk factors for aspirin-induced gastric mucosal injury is not sufficient to prevent these gastric mucosal lesions.Methods:We recruited aspirin takers as the exposed group and healthy volunteers as the control group.The exposed group was categorized into two subgroups such as subgroup A as gastric mucosal injury diagnosed by gastroscopy,including erosion,ulcer or bleeding of the esophagus,stomach,or duodenum;subgroup B as no injury of the gastric mucosa was detected by gastroscopy.Clinical information was collected,and 53 single nucleotide polymorphisms were evaluated.Results:Among 385 participants,234 were in the aspirin-exposed group.According to gastroscopy,82 belonged to subgroup A,91 belonged to subgroup B,and gastroscopic results of 61 participants were not available.Using the Chi-square test and logistic regression,we found that peptic ulcer history (odds ratio [OR] =5.924,95% confidence intervals [CI]:2.115-16.592),dual anti-platelet medication (OR =3.443,95% CI:1.154-10.271),current Helicobacterpylori infection (OR =2.242,95% CI:1.032-4.870),male gender (OR =2.211,95% CI:1.027-4.760),GG genotype ofrs2243086 (OR =4.516,95% CI:1.180-17.278),and AA genotype ofrs 1330344 (OR =2.178,95% CI:1.016-4.669) were more frequent in subgroup A than subgroup B.In aspirin users who suffered from upper gastrointestinal bleeding,the frequency of the TT genotype ofrs2238631 and TT genotype ofrs2243100 was higher than in those without upper gastrointestinal bleeding.Conclusions:Peptic ulcer history,dual anti-platelet medication,H.pylori current infection,and male gender were possible clinical risk factors for aspirin-induced gastric mucosal injury.GG genotype of rs2243086 and AA genotype of rs 1330344 were possible genetic risk factors.TT genotype ofrs2238631 and TT genotype of rs2243100 may be risk factors for upper gastrointestinal bleeding in aspirin users.

  10. Risk factors and clinical presentation of craniocervical arterial dissection: A prospective study

    Thomas Lucy C

    2012-09-01

    Full Text Available Abstract Background Craniocervical arterial dissection is a major cause of ischaemic stroke in young adults. The pathogenesis is not fully understood but is thought to be related to a combination of an intrinsic weakness in the arterial wall and an external trigger. Intrinsic susceptibility is thought to be a generalised arteriopathy, vascular anomaly or genetic predisposition. Proposed extrinsic factors include recent viral infection and minor mechanical trauma to the neck, including neck manipulation, which has raised concerns amongst manual practitioners in particular as to the appropriate screening of patients and avoidance of more vigorous therapeutic techniques. The presenting features of dissection may mimic a musculoskeletal presentation, creating a diagnostic dilemma for primary care practitioners. Early recognition is critical so that appropriate management can be commenced. The aims of this study are to prospectively investigate young patients ≤55 years admitted to hospital with radiologically diagnosed craniocervical arterial dissection compared to matched controls with stroke but not dissection, to identify risk factors and early presenting clinical features, so these may be more readily identified by primary care practitioners. Methods Patients ≤ 55 years presenting to hospital with craniocervical arterial dissection and controls will have their medical records reviewed and be interviewed and questioned about possible risk factors, preceding events to admission such as recent neck trauma, and presenting clinical features including any preceding transient ischaemic features. Clinical assessment will include a connective tissue screening examination to identify subclinical connective tissue disorders. Radiology and blood screening will be reviewed for typical features and inflammatory markers. Functional outcome will be reviewed to determine the burden of the stroke. Discussion This study will provide descriptive and

    Incidence of thyroid cancer is increasing in Spain and worldwide. Overall thyroid cancer survival is very high, and stratification systems to reliably identify patients with worse prognosis have been developed. However, marked differences exist between the different specialists in clinical management of low-risk patients with thyroid carcinoma. Almost half of all papillary thyroid carcinomas are microcarcinomas, and 90% are tumors < 2 cm that have a particularly good prognosis. However, they are usually treated more aggressively than needed, despite the lack of adequate scientific support. Surgery remains the gold standard treatment for these tumors. However, lobectomy may be adequate in most patients, without the need for total thyroidectomy. Similarly, prophylactic lymph node dissection of the central compartment is not required in most cases. This more conservative approach prevents postoperative complications such as hypoparathyroidism or recurrent laryngeal nerve injury. Postoperative radioiodine remnant ablation and strict suppression of serum thyrotropin, although effective for the more aggressive forms of thyroid cancer, have not been shown to be beneficial for the treatment of low risk patients, and may impair their quality of life. This guideline provides recommendations from the task force on thyroid cancer of the Spanish Society of Endocrinology and Nutrition for adequate management of patients with low-risk thyroid cancer.

    Full Text Available Purpose : Transient tachypnea of the newborn (TTN is usually benign and improves within 72 hours. However, it can also progress to prolonged tachypnea over 72 hours, profound hypoxemia, respiratory failure, and even death. The aim of this study is to find predictable risk factors and describe the clinical courses and outcomes of prolonged TTN (PTTN. Methods : The medical records of 107 newborns, &gt;35+0 weeks of gestational age with TTN, who were admitted to the NICU at Seoul Asan Medical Center from January 2001 to September 2007 were reviewed. They were divided into 2 groups based on duration of tachypnea. PTTN was defined as tachypnea ?#247;2 hours of age, and simple TTN (STTN as tachypnea &lt;72 hours of age. We randomly selected 126 healthy-term newborns as controls. We evaluated neonatal and maternal demographic findings, and various clinical factors. Results : Fifty-five infants (51% with total TTN were PTTN. PTTN infants had grunting, tachypnea &gt;90/min, FiO2 &gt;0.4, and required ventilator care more frequently than STTN infants. PTTN had lower level of serum total protein and albumin than STTN. The independent predictable risk factors for PTTN were grunting, maximal respiration rate &gt;90/min, and FiO2 &gt;0.4 within 6 hours of life. Conclusion : When a newborn has grunting, respiration rate &gt;90/min, and oxygen requirement &gt;0.4 of FiO2 within 6 hours of life, the infant is at high risk of having persistent tachypnea ?#247;2 hours. We need further study to find the way to reduce PTTN.

    Introduction: Despite increasing the use of magnetic resonance imaging (MRI), cerebral venous sinus thrombosis (CVST) has remained an under-diagnosed condition. In this study, characteristics and frequency of various risk factors of CVST patients in a tertiary referral hospital were closely assessed. Methods: Patients with an unequivocal diagnosis of CVST confirmed by MRI and magnetic resonance venography during 6 years of the study were included. All data from the onset of symptoms regarding clinical signs and symptoms, hospital admission, seasonal distribution, medical and drug history, thrombophilic profile, D-dimer, neuroimaging, cerebrospinal fluid findings, mortality, and outcome were collected and closely analyzed. Result: A total of 53 patients with female to male ratio of 3.07 and mean age of 33.7 years were included in the study. Headache and papilledema were the most frequent clinical features (44 and 36 patients, respectively). An underlying disease (diagnosed previously or after admission) was the most common identified risk factor for CVST in both females and males (21 patients). A total of 15 women used the oral contraceptive pill (OCP) where 12 of them had simultaneously other predisposing factors. Overall, 19 patients (36%) had more than one contributing factor. D-dimer had a sensitivity of 71.4% in CVST patients. The mortality of patients in this study was 3.7% (n = 2). Focal neurologic deficit and multicranial nerve palsy were associated with poor outcome which defined as death, recurrence, and massive intracranial hemorrhage due to anticoagulation (P = 0.050 and 0.004, respectively). Conclusion: Unlike most of the CVST studies in which OCP was the main factor; in this study, an underlying disease was the most identified cause. Considering the high probability of multiple risk factors in CVST that was shown by this study, appropriate work up should be noted to uncover them. PMID:27695236

    2016-11-01

    OBJECTIVE Patients treated for Chiari I malformation (CM-I) with posterior fossa decompression (PFD) may occasionally and unpredictably develop postoperative hydrocephalus. The clinical risk factors predictive of this type of Chiari-related hydrocephalus (CRH) are unknown. The authors' objective was to evaluate their experience to identify risk factors that may predict which of these patients undergoing PFD will develop CRH after surgery. METHODS The authors performed a retrospective clinical chart review of all patients who underwent PFD surgery and duraplasty for CM-I at the Primary Children's Hospital in Utah from June 1, 2005, through May 31, 2015. Patients were dichotomized based on the need for long-term CSF diversion after PFD. Analysis included both univariate and multivariable logistic regression analyses. RESULTS The authors identified 297 decompressive surgeries over the period of the study, 22 of which required long-term postoperative CSF diversion. On multivariable analysis, age < 6 years old (OR 3.342, 95% CI 1.282-8.713), higher intraoperative blood loss (OR 1.003, 95% CI 1.001-1.006), and the presence of a fourth ventricular web (OR 3.752, 95% CI 1.306-10.783) were significantly associated with the need for long-term CSF diversion after decompressive surgery. CONCLUSIONS Younger patients, those with extensive intraoperative blood loss, and those found during surgery to have a fourth ventricular web were at higher risk for the development of CRH. Clinicians should be alert to evidence of CRH in this patient population after PFD surgery.

  16. Analysis of risk factors and clinical manifestations associated with Clostridium difficile disease in Serbian hospitalized patients

    Stojanović Predrag

    Full Text Available Abstract Clostridium difficile is the leading cause of infectious diarrhoea in hospitalized patients. The aim of this study was to determine the risk factors important for the development of hospital-acquired Clostridium difficile-associated disease and clinical manifestations of Clostridium difficile-associated disease. The clinical trial group included 37 hospitalized patients who were selected according to the inclusion criteria. A control group of 74 hospitalized patients was individually matched with cases based on hospital, age (within 4 years, sex and month of admission.Clostridium difficile-associated disease most commonly manifested as diarrhoea (56.76% and colitis (32%, while in 8.11% of patients, it was diagnosed as pseudomembranous colitis, and in one patient, it was diagnosed as fulminant colitis. Statistically significant associations (p < 0.05 were found with the presence of chronic renal failure, chronic obstructive pulmonary disease, cerebrovascular accident (stroke and haemodialysis. In this study, it was confirmed that all the groups of antibiotics, except for tetracycline and trimethoprim-sulfamethoxazole, were statistically significant risk factors for Clostridium difficile-associated disease (p < 0.05. However, it was difficult to determine the individual role of antibiotics in the development of Clostridium difficile-associated disease. Univariate logistic regression also found that applying antibiotic therapy, the duration of antibiotic therapy, administration of two or more antibiotics to treat infections, administering laxatives and the total number of days spent in the hospital significantly affected the onset of Clostridium difficile-associated disease (p < 0.05, and associations were confirmed using the multivariate model for the application of antibiotic therapy (p = 0.001, duration of antibiotic treatment (p = 0.01, use of laxatives (p = 0.01 and total number of days spent in the hospital (p = 0.001.

  17. Bone diseases associated with human immunodeficiency virus infection: pathogenesis, risk factors and clinical management.

    Bongiovanni, Marco; Tincati, Camilla

    2006-06-01

    Bone disorders such as osteopenia and osteoporosis have been recently reported in patients infected with the human immunodeficiency virus (HIV), but their etiology remains still unknown. The prevalence estimates vary widely among the different studies and can be affected by concomitant factors such as the overlapping of other possible conditions inducing bone loss as lypodystrophy, advanced HIV-disease, advanced age, low body weight or concomitant use of other drugs. All the reports at the moment available in the literature showed a higher than expected prevalence of reduced bone mineral density (BMD) in HIV-infected subjects both naïve and receiving potent antiretroviral therapy compared to healthy controls. This controversial can suggest a double role played by both antiretroviral drugs and HIV itself due to immune activation and/or cytokines disregulation. An improved understanding of the pathogenesis of bone disorders can result in better preventative and therapeutic measures. However, the clinical relevance and the risk of fractures remains undefined in HIV-population. The clinical management of osteopenia and osteoporosis in HIV-infected subjects is still being evaluated. Addressing potential underlying bone disease risk factors (e.g., smoking and alcohol intake, use of corticosteroids, advanced age, low body weight), evaluating calcium and vitamin D intake, and performing dual x-ray absorptiometry in HIV-infected individuals who have risk factors for bone disease can be important strategies to prevent osteopenia and osteoporosis in this population. The administration of bisphosphonates (e.g., alendronate), with calcium and vitamin D supplementation, may be a reasonable and effective option to treat osteoporosis in these subjects.

    2013-01-01

    Full Text Available Interstitial lung disease (ILD is a common and severe complication of idiopathic inflammatory myopathies (IIM. The aim of our study was to identify risk factors for ILD by evaluating both clinical and biochemical features in IIM patients with or without ILD. From January 2008 to December 2011, medical records of 134 IIM patients in our rheumatology unit were reviewed. The patients were divided into ILD group (83 patients and non-ILD group (51 patients. The clinical features and laboratory findings were compared. The univariable analyses indicated that arthritis/arthralgia (54.2% versus 17.6%, P<0.05, Mechanic’s hand (16.9% versus 2.0%, P<0.05, Raynaud’s phenomenon (36.1% versus 2.0%, P<0.05, heliotrope rash (44.6% versus 19.6%, P<0.05, fever (43.4% versus 21.6%, P<0.05, elevated ESR (60.2% versus 35.3%, P<0.05, elevated CRP (55.4% versus 31.4%, P<0.05, or anti-Jo-1 antibody (20.5% versus 5.9%, P<0.05 were risk factors for developing ILD in IIM. Multivariable unconditional logistic regression analysis that showed arthritis/arthralgia (OR 7.1, 95% CI 2.8–18.1, Raynaud’s phenomenon (OR 29.1, 95% CI 3.6–233.7, and amyopathic dermatomyositis (ADM (OR 20.2, 95% CI 2.4–171.2 were the independent risk factors for developing ILD in IIM.

    2015-01-01

    Full Text Available Background: Deep venous thrombosis (DVT contributes significantly to the morbidity and mortality of neurosurgical patients; however, no data regarding lower extremity DVT in postoperative Chinese neurosurgical patients have been reported. Materials and Methods: From January 2012 to December 2013, 196 patients without preoperative DVT who underwent neurosurgical operations were evaluated by color Doppler ultrasonography and D-dimer level measurements on the 3rd, 7th, and 14th days after surgery. Follow-up clinical data were recorded to determine the incidence of lower extremity DVT in postoperative neurosurgical patients and to analyze related clinical features. First, a single factor analysis, Chi-square test, was used to select statistically significant factors. Then, a multivariate analysis, binary logistic regression analysis, was used to determine risk factors for lower extremity DVT in postoperative neurosurgical patients. Results: Lower extremity DVT occurred in 61 patients, and the incidence of DVT was 31.1% in the enrolled Chinese neurosurgical patients. The common symptoms of DVT were limb swelling and lower extremity pain as well as increased soft tissue tension. The common sites of venous involvement were the calf muscle and peroneal and posterior tibial veins. The single factor analysis showed statistically significant differences in DVT risk factors, including age, hypertension, smoking status, operation time, a bedridden or paralyzed state, the presence of a tumor, postoperative dehydration, and glucocorticoid treatment, between the two groups (P < 0.05. The binary logistic regression analysis showed that an age greater than 50 years, hypertension, a bedridden or paralyzed state, the presence of a tumor, and postoperative dehydration were risk factors for lower extremity DVT in postoperative neurosurgical patients. Conclusions: Lower extremity DVT was a common complication following craniotomy in the enrolled Chinese neurosurgical

  20. Clinical and non-clinical depressive symptoms and risk of long-term sickness absence among female employees in the Danish eldercare sector

    Background: Depression has a high point and life time prevalence and is a major cause of reduced work ability and long-term sickness absence (LTSA). Less is known of the extent to which non-clinical depressive symptoms are related to the risk of LTSA. The aim of this study was to investigate how......, and occupational group. Limitations: Missing information on the cause of sickness absence and prevalent somatic illness. Conclusion: A clear dose–response relationship exists between increasing depressive symptoms and risk of LTSA. The adverse effect of non-clinical depressive symptoms on LTSA already manifests...... non-clinical and clinical depressive symptoms are prospectively associated to subsequent LTSA. Methods: In a cohort study of 6985 femaleemployees fromthe Danish eldercare sector depressive symptoms were measured by the Major Depression Inventory (MDI) and scores (0–50) were divided into groups of 0...

  1. Oral surgery in elderly patients: clinical/surgical considerations and risk assessment

    Catarina Ribeiro Barros de Alencar

    2011-04-01

    Full Text Available Introduction: The need for oral surgery has been considerably increasing in elderly population in order to allow the balance of their masticatory, aesthetic, and phonetic functions through adapting the oral tissues for the appropriate placement of the prosthetic devices, thereby impacting positively on the subject’s health. Objective: This article aimed to review the literature on both clinical and surgical considerations required to the satisfactory treatment of elderly patients in clinical routine practice, focusing particularly on cases whose treatment choice is a surgical procedure. Literature review: The most commonly performed surgeries in elderly patients, nowadays, are tooth extractions, pre-prosthetic surgeries and osseointegrated implants. Therefore, the physiological features inherent to such cases should be considered, especially those that involve the monitoring of glycemic and blood pressure levels, osteoporosis, medication use, and many other conditions demanding special attention for elderly patient treatment at dental office. Conclusion: Due to the fragility intrinsic to elderly individuals, the surgery at this stage of life requires caution in relation to a comprehensive clinical examination and also to a careful evaluation of the surgical risks in order to analyze the correct indication of the surgery and thereby to ensure patient’s well-being.

  2. Pilot Clinical Trial of Indocyanine Green Fluorescence-Augmented Colonoscopy in High Risk Patients

    Rahul A. Sheth

    2016-01-01

    Full Text Available White light colonoscopy is the current gold standard for early detection and treatment of colorectal cancer, but emerging data suggest that this approach is inherently limited. Even the most experienced colonoscopists, under optimal conditions, miss at least 15–25% of adenomas. There is an unmet clinical need for an adjunctive modality to white light colonoscopy with improved lesion detection and characterization. Optical molecular imaging with exogenously administered organic fluorochromes is a burgeoning imaging modality poised to advance the capabilities of colonoscopy. In this proof-of-principle clinical trial, we investigated the ability of a custom-designed fluorescent colonoscope and indocyanine green, a clinically approved fluorescent blood pool imaging agent, to visualize polyps in high risk patients with polyposis syndromes or known distal colonic masses. We demonstrate (1 the successful performance of real-time, wide-field fluorescence endoscopy using off-the-shelf equipment, (2 the ability of this system to identify polyps as small as 1 mm, and (3 the potential for fluorescence imaging signal intensity to differentiate between neoplastic and benign polyps.

    2015-01-01

    Introduction: In recent years, researchers and clinicians do not treat passive suicidal ideation as a clinically relevant risk factor for suicide, while underestimating the strength of this desire to die, compared with making a plan for suicide in individuals having active suicidal ideation. This research study is clinically prospective, cross-sequential, but also partly retrospective because it involves also variables from the past, such as patients’ history data (number of suicidal attempts...

  4. Prostate cancer risk-associated genetic markers and their potential clinical utility

    Jianfeng Xu; Jielin Sun; S Lilly Zheng

    2013-01-01

    Prostate cancer (PCa) is one of the most common cancers among men in Western developed countries and its incidence has increased considerably in many other parts of the world,including China.The etiology of PCa is largely unknown but is thought to be multifactorial,where inherited genetics plays an important role.In this article,we first briefly review results from studies of familial aggregation and genetic susceptibility to PCa.We then recap key findings of rare and high-penetrance PCa susceptibility genes from linkage studies in PCa families.We devote a significant portion of this article to summarizing discoveries of common and low-penetrance PCa risk-associated single-nucleotide polymorphisms (SNPs) from genetic association studies in PCa cases and controls,especially those from genome-wide association studies (GWASs).A strong focus of this article is to review the literature on the potential clinical utility of these implicated genetic markers.Most of these published studies described PCa risk estimation using a genetic score derived from multiple risk-associated SNPs and its utility in determining the need for prostate biopsy.Finally,we comment on the newly proposed concept of genetic score; the notion is to treat it as a marker for genetic predisposition,similar to family history,rather than a diagnostic marker to discriminate PCa patients from non-cancer patients.Available evidence to date suggests that genetic score is an objective and better measurement of inherited risk of PCa than family history.Another unique feature of this article is the inclusion of genetic association studies of PCa in Chinese and Japanese populations.

  5. READMIT: a clinical risk index to predict 30-day readmission after discharge from acute psychiatric units.

    Vigod, Simone N; Kurdyak, Paul A; Seitz, Dallas; Herrmann, Nathan; Fung, Kinwah; Lin, Elizabeth; Perlman, Christopher; Taylor, Valerie H; Rochon, Paula A; Gruneir, Andrea

    2015-02-01

    Our aim was to create a clinically useful risk index, administered prior to discharge, for determining the probability of psychiatric readmission within 30 days of hospital discharge for general psychiatric inpatients. We used population-level sociodemographic and health administrative data to develop a predictive model for 30-day readmission among adults discharged from an acute psychiatric unit in Ontario, Canada (2008-2011), and converted the final model into a risk index system. We derived the predictive model in one-half of the sample (n = 32,749) and validated it in the other half of the sample (n = 32,750). Variables independently associated with 30-day readmission (forming the mnemonic READMIT) were: (R) Repeat admissions; (E) Emergent admissions (i.e. harm to self/others); (D) Diagnoses (psychosis, bipolar and/or personality disorder), and unplanned Discharge; (M) Medical comorbidity; (I) prior service use Intensity; and (T) Time in hospital. Each 1-point increase in READMIT score (range 0-41) increased the odds of 30-day readmission by 11% (odds ratio 1.11, 95% CI 1.10-1.12). The index had moderate discriminative capacity in both derivation (C-statistic = 0.631) and validation (C-statistic = 0.630) datasets. Determining risk of psychiatric readmission for individual patients is a critical step in efforts to address the potentially avoidable high rate of this negative outcome. The READMIT index provides a framework for identifying patients at high risk of 30-day readmission prior to discharge, and for the development, evaluation and delivery of interventions that can assist with optimizing the transition to community care for patients following psychiatric discharge.

  6. Identification and Characterization of Prodromal Risk Syndromes in Young Adolescents in the Community: A Population-Based Clinical Interview Study.

    2012-02-01

    While a great deal of research has been conducted on prodromal risk syndromes in relation to help-seeking individuals who present to the clinic, there is a lack of research on prodromal risk syndromes in the general population. The current study aimed first to establish whether prodromal risk syndromes could be detected in non-help-seeking community-based adolescents and secondly to characterize this group in terms of Axis-1 psychopathology and general functioning. We conducted in-depth clinical interviews with a population sample of 212 school-going adolescents in order to assess for prodromal risk syndromes, Axis-1 psychopathology, and global (social\\/occupational) functioning. Between 0.9% and 8% of the community sample met criteria for a risk syndrome, depending on varying disability criteria. The risk syndrome group had a higher prevalence of co-occurring nonpsychotic Axis-1 psychiatric disorders (OR = 4.77, 95% CI = 1.81-12.52; P < .01) and poorer global functioning (F = 24.5, df = 1, P < .0001) compared with controls. Individuals in the community who fulfill criteria for prodromal risk syndromes demonstrate strong similarities with clinically presenting risk syndrome patients not just in terms of psychotic symptom criteria but also in terms of co-occurring psychopathology and global functioning.

  7. Development of a Simple Clinical Risk Score for Early Prediction of Severe Dengue in Adult Patients.

    Ing-Kit Lee

    , irrespective of the day of illness onset, suggesting that our simple risk score can be easily implemented in resource-limited countries for early prediction of dengue patients at risk of SD provided that they have rapid dengue confirmed tests. For patients with other acute febrile illnesses or bacterial infections usually have SD risk score of >1. Thus, these scoring algorithms cannot totally replace good clinical judgement of the physician, and most importantly, early differentiating dengue from other febrile illnesses is critical for appropriate monitoring and management.

    Full Text Available OBJECTIVES: To evaluate transrectal ultrasound, amplitude Doppler ultrasound, conventional T2-weighted magnetic resonance imaging, spectroscopy and dynamic contrast-enhanced magnetic resonance imaging in localizing and locally staging low-risk prostate cancer. INTRODUCTION: Prostate cancer has been diagnosed at earlier stages and the most accepted classification for low-risk prostate cancer is based on clinical stage T1c or T2a, Gleason score <6, and prostate-specific antigen (PSA <10 ng/ml. METHODS: From 2005 to 2006, magnetic resonance imaging was performed in 42 patients, and transrectal ultrasound in 26 of these patients. Seven patients were excluded from the study. Mean patient age was 64.94 years and mean serum PSA was 6.05 ng/ml. The examinations were analyzed for tumor identification and location in prostate sextants, detection of extracapsular extension, and seminal vesicle invasion, using surgical pathology findings as the gold standard. RESULTS: Sixteen patients (45.7% had pathologically proven organ-confined disease, 11 (31.4% had positive surgical margin, 8 (28.9% had extracapsular extension, and 3 (8.6% presented with extracapsular extension and seminal vesicle invasion. Sensitivity, specificity, positive predictive value (PPV, negative predictive value (NPV and accuracy values for localizing low-risk prostate cancer were 53.1%, 48.3%, 63.4%, 37.8% and 51.3% for transrectal ultrasound; 70.4%, 36.2%, 65.1%, 42.0% and 57.7% for amplitude Doppler ultrasound; 71.5%, 58.9%, 76.6%, 52.4% and 67.1% for magnetic resonance imaging; 70.4%, 58.7%, 78.4%, 48.2% and 66.7% for magnetic resonance spectroscopy; 67.2%, 65.7%, 79.3%, 50.6% and 66.7% for dynamic contrast-enhanced magnetic resonance imaging, respectively. Sensitivity, specificity, PPV, NPV and accuracy values for detecting extracapsular extension were 33.3%, 92%, 14.3%, 97.2% and 89.7% for transrectal ultrasound and 50.0%, 77.6%, 13.7%, 95.6% and 75.7% for magnetic resonance imaging

  9. Care zoning. A pragmatic approach to enhance the understanding of clinical needs as it relates to clinical risks in acute in-patient unit settings.

    The process of risk assessment which should inform and help identify clinical needs is often seen as a tick box and task-focussed approach. While on the surface this provides a sense of security that forms have been completed, we often fail to communicate in a meaningful manner about the clinical needs identified, which would assist in supporting the care planning delivery processes. A clinical practice improvement (CPI) project implemented a care zoning framework as an evidenced-based process that provides pragmatic support to nurses who are required to continually assess, implement, and evaluate plans to address clinical need across three acute mental health inpatient settings. Risk descriptors informed by the New South Wales (NSW) Mental Health Assessment & Outcome Tools (MHAOT) criteria were developed and described in behavioural contexts in order to improve the project's reliability and translation. A pragmatic traffic light tool was used to share clinical information across three agreed care zones, red (high clinical need), amber (medium clinical need), and green (low clinical need). Additionally nurses were asked to utilise a shift review form in the context of supporting the recording of care zoning and promoting action-orientated note writing. The introduction of care zoning has enthused the nursing teams and the mental health service to adopt care zoning as a supervisory framework that increases their capacity to communicate clinical needs, share information, and gain invaluable support from one another in addressing clinical needs. This includes increased opportunities for staff to feel supported in asking for assistance in understanding and addressing complex clinical presentations.

  10. Ontology-Based Clinical Decision Support System for Predicting High-Risk Pregnant Woman

    Umar Manzoor

    2015-12-01

    Full Text Available According to Pakistan Medical and Dental Council (PMDC, Pakistan is facing a shortage of approximately 182,000 medical doctors. Due to the shortage of doctors; a large number of lives are in danger especially pregnant woman. A large number of pregnant women die every year due to pregnancy complications, and usually the reason behind their death is that the complications are not timely handled. In this paper, we proposed ontology-based clinical decision support system that diagnoses high-risk pregnant women and refer them to the qualified medical doctors for timely treatment. The Ontology of the proposed system is built automatically and enhanced afterward using doctor’s feedback. The proposed framework has been tested on a large number of test cases; experimental results are satisfactory and support the implementation of the solution.

    1995-01-01

    Increased morbidity and mortality from atherosclerotic vascular disease were observed in subjects with slightly elevated urinary albumin excretion rate (UAER), known as microalbuminuria. Therefore, the association between microalbuminuria and established atherogenic risk factors was studied...... in clinically healthy subjects. All healthy 40-65 year-old participants with microalbuminuria, examined within the first 21 months of The Copenhagen City Heart Study, were invited, and 28 were studied. An age- and sex-matched group of 60 randomly chosen subjects with normoalbuminuria served as control......Hg; P = 0.008, respectively), and serum apolipoprotein (apo) A-1 concentration was lower (1.30 (1.20-1.37) vs. 1.42 (1.36-1.47) milligrams; P = 0.02) in comparison with the normoalbuminuric group. Furthermore, serum HDL-cholesterol concentration tended to be lower, whereas body weight, body mass index...

    Fifty volunteer, asymptomatic sexually active university female students were examined and inquired, in order to find risk factors predictive of Chlamydia trachomatis infection. Epidemiologic and behavioral factors (age, number of sexual partners, oral contraceptives use and history of previous sexually transmitted diseases) were found to be similar among the studied group and published data for North American female college students, but barrier contraceptive methods use was found to be different. Twenty two per cent of the sample had clinical cervicitis, and 30% had subclinical. If the screening models proposed by different authors would have been applied, between a 32% and 72% of the sample would have been selectively for the presence of Chlamydia trachomatis. It is concluded that international sugerences about Chlamydia trachomatis screening should be adopted until national experiences are made.

    Stem cells are likely to be used as an alternate source of biological material for neural transplantation to treat Parkinson's disease in the not too distant future. Among the several ethical criteria that must be fulfilled before proceeding with clinical research, a favourable benefit to risk ratio must be obtained. The potential benefits to the participant and to society are evaluated relative to the risks in an attempt to offer the participants a reasonable choice. Through examination of preclinical studies transplanting stem cells in animals and the transplantation of fetal tissue in patients with Parkinson's disease, a current set of potential benefits and risks for neural transplantation of stem cells in clinical research of Parkinson's disease are derived. The potential benefits to research participants undergoing stem cell transplantation are relief of parkinsonian symptoms and decreasing doses of parkinsonian drugs. Transplantation of stem cells as a treatment for Parkinson's disease may benefit society by providing knowledge that can be used to help determine better treatments in the future. The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration, immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection. Although some of these risks are general to neurosurgical transplantation and may not be reduced for participants, the potential risk of tumour formation and inappropriate stem cell migration must be minimised before obtaining a favourable potential benefit to risk calculus and to provide participants with a reasonable choice before they enroll in clinical studies.

    About 30% of patients with cirrhosis have diabetes mellitus (DM). Nowadays, it is a matter for debate whether type 2 DM in the absence of obesity and hypertriglyceridemia may be a risk factor for chronic liver disease. DM,which develops as a complication of cirrhosis, is known as "hepatogenous diabetes". Insulin resistance in muscular and adipose tissues and hyperinsulinemia seem to be the pathophysiologic bases of diabetes in liver disease. An impaired response of the islet β-cells of the pancreas and hepatic insulin resistance are also contributory factors. Non-alcoholic fatty liver disease, alcoholic cirrhosis, chronic hepatitis C (CHC) and hemochromatosis are more frequently associated with DM. Insulin resistance increases the failure of the response to treatment in patients with CHC and enhances progression of fibrosis. DM in cirrhotic patients may be subclinical.Hepatogenous diabetes is clinically different from that of type 2 DM, since it is less frequently associated with microangiopathy and patients more frequently suffer complications of cirrhosis. DM increases the mortality of cirrhotic patients. Treatment of the diabetes is complex due to liver damage and hepatotoxicity of oral hypoglycemic drugs. This manuscript will review evidence that exists in relation to: type 2 DM alone or as part of the metabolic syndrome in the development of liver disease;factors involved in the genesis of hepatogenous diabetes;the impact of DM on the clinical outcome of liver disease; the management of DM in cirrhotic patients and the role of DM as a risk factor for the occurrence and exacerbation of hepatocellular carcinoma.

    Little evidence exists examining cardiovascular risk factors among Asian Americans and how social determinants such as nativity status and education pattern risk in the United States (U.S.) context. We used the 2011-2014 National Health and Nutrition Examination Survey, which purposely oversampled Asian Americans from 2011 to 2014, and examined prevalence of Type II diabetes, smoking and obesity for Asian Americans (n=1363) and non-Latino Whites (n=4121). We classified Asian Americans as U.S. or foreign-born and by years in the U.S. Obesity status was based on standard body mass index (BMI) cut points of ≥30kg/m(2) and Asian-specific cut points (BMI≥25kg/m(2)) that may be more clinically relevant for this population. We fit separate logistic regression models for each outcome using complex survey design methods and tested for the joint effect of race, nativity and education on each outcome.Diabetes and obesity prevalence (applying Asian-specific BMI cut points) were higher among Asian Americans when compared to non-Latino Whites but smoking prevalence was lower. These patterns remained in fully adjusted models and showed small increases with longer duration in the U.S. Joint effects models showed higher odds of prevalent Type II diabetes and obesity (Asian-specific) for foreign-born Asians, regardless of years in the U.S. and education, when compared to non-Latino Whites with high education. Smoking models showed significant interaction effects between race and education for non-Latino Whites only. Our study supports the premise that social as well as clinical factors should be considered when developing health initiatives for Asian Americans.

    This study was aimed to determine the risk factors of Carbapenem-resistant Enterobacteriaceae (CRE) nosocomial infections and assess the clinical outcomes. A case-case-control design was used to compare two groups of case patients with control patients from March 2010 to November 2014 in China. Risk factors for the acquisition of CRE infections and clinical outcomes were analyzed by univariable and multivariable analysis. A total of 94 patients with CRE infections, 93 patients with Carbapenem-susceptible Enterobacteriaceae (CSE) infections, and 93 patients with organisms other than Enterobacteriaceae infections were enrolled in this study. Fifty-five isolates were detected as the carbapenemase gene. KPC-2 was the most common carbapenemase (65.5 %, 36/55), followed by NDM-1 (16.4 %, 9/55), IMP-4 (14.5 %, 8/55), NDM-5 (1.8 %, 1/55), and NDM-7 (1.8 %, 1/55). Multivariable analysis implicated previous use of third or fourth generation cephalosporins (odds ratio [OR], 4.557; 95 % confidence interval [CI], 1.971-10.539; P Enterobacteriaceae with a high meropenem MIC (≥8 mg/L) was shorter than that of patients with a low meropenem MIC (2,4, and ≤ 1 mg/L). In conclusion, CRE nosocomial infections are associated with prior exposure to third or fourth generation cephalosporins and carbapenems. Patients infected with CRE had poor outcome and high mortality, especially high meropenem MIC (≥8 mg/L). Appropriate definitive treatment to CRE infections in the patient is essential.

  17. Stroke Mortality, Clinical Presentation and Day of Arrival: The Atherosclerosis Risk in Communities (ARIC Study

    Emily C. O'Brien

    2011-01-01

    Full Text Available Background. Recent studies report that acute stroke patients who present to the hospital on weekends have higher rates of 28-day mortality than similar patients who arrive during the week. However, how this association is related to clinical presentation and stroke type has not been systematically investigated. Methods and Results. We examined the association between day of arrival and 28-day mortality in 929 validated stroke events in the ARIC cohort from 1987–2004. Weekend arrival was defined as any arrival time from midnight Friday until midnight Sunday. Mortality was defined as all-cause fatal events from the day of arrival through the 28th day of followup. The presence or absence of thirteen stroke signs and symptoms were obtained through medical record review for each event. Binomial logistic regression was used to estimate odds ratios and 95% confidence intervals (OR; 95% CI for the association between weekend arrival and 28-day mortality for all stroke events and for stroke subtypes. The overall risk of 28-day mortality was 9.6% for weekday strokes and 10.1% for weekend strokes. In models controlling for patient demographics, clinical risk factors, and event year, weekend arrival was not associated with 28-day mortality (0.87; 0.51, 1.50. When stratified by stroke type, weekend arrival was not associated with increased odds of mortality for ischemic (1.17, 0.62, 2.23 or hemorrhagic (0.37; 0.11, 1.26 stroke patients. Conclusions. Presence or absence of thirteen signs and symptoms was similar for weekday patients and weekend patients when stratified by stroke type. Weekend arrival was not associated with 28-day all-cause mortality or differences in symptom presentation for strokes in this cohort.

    José Eduardo Gomes Domingues

    Full Text Available INTRODUCTION: Periodontal disease is an inflammatory response to bacteria that reside in the gum tissue and can have systemic repercussion. OBJECTIVE: The aim of this study was to assess the relationship between periodontitis and markers of cardiovascular risk. MATERIAL AND METHOD: Ninety selected patients were assigned into two groups in accordance with their levels of probing pocket depth (PPD and Clinical Attachment Level (CAL: control group, n= 45 (< 4 sites with PPD ≥ 4.0 mm and CAL ≥ 3.0 mm and case group, n= 45 (≥ 30% of sites with PPD ≥ 4.0 mm and CAL ≥3.0 mm. Plasma concentrations of C-reactive protein, high sensitive CRP, high-density lipoproteins (HDL-c and electronegative low density lipoproteins (LDL were assessed in all participants. Data from medical history and socioeconomic level were also collected from patients. RESULT: Plasma levels of HDL-c were lower in subjects with periodontal disease (p = 0.016 and were inversely associated with the number of sites with PPD ≥ 3 mm (rho= -0.325 and number of sites with PPD ≥ 3 mm and CAL ≥ 3 mm (rho= -0.216. These associations remained significant after adjustments for dental plaque and smoking using Univariate Analysis of Covariance (p < 0.05. Adjusted odds ratio between periodontal disease and levels of HDL-c was 0.94 (CI95% 0.88-0.99 after adjusting for age, smoking and dental plaque. Other investigated markers of cardiovascular risk were not related to periodontal disease. CONCLUSION: Clinical parameters of periodontitis were inversely associated with plasma concentrations of HDL-c.

  19. Fatherhood and depression: a review of risks, effects, and clinical application.

    Spector, Aaron Z

    2006-10-01

    This literature review attempted to compile a complete evaluation of the presentation, risks, and subsequent effects upon a family in relation to paternal depression. Clinical applications are reviewed as well. As with women, fathers will present with a dysphoric mood, but unlike their female counterparts, depressed men often experience a change in social behavior. Withdrawal from social situations, indecisiveness, cynicism, and an irritable mood are often found as hallmark signs of depression in the adult male. Life stress, or family stress and low social support, are risk factors associated with depression among fathers. Marital difficulties may be the most common trigger for first-time depression in husbands just as divorce amplifies depressive episodes, especially when children are involved. A variety of treatments have proven effective for depressed fathers including traditional psycho-dynamic, CBT, and group therapy. Therapy is effective when it can be initiated and continued but research repeatedly showed that men seek it out far less than women. Effective outreach programs to encourage treatment among depressed fathers are recommended.

  20. Infections caused by carbapenemase-producing Enterobacteriaceae: risk factors, clinical features and prognosis.

    Paño Pardo, José Ramón; Serrano Villar, Sergio; Ramos Ramos, Juan Carlos; Pintado, Vicente

    2014-12-01

    Infections caused by carbapenem-producing Enterobacteriaceae (CPE) can present as several infectious syndromes, but they primarily present as respiratory, urinary and blood stream infections (primary or catheter-related) that are usually found as nosocomial or healthcare-associated infections. The risk of CPE infection is influenced by individual factors, such as the length of the hospital stay and their exposure to invasive procedures and/or to antimicrobials. Of note, exposure to several antimicrobials, not only carbapenems, has been linked to CPE colonization; the duration of antibiotic exposure is one of the primary drivers of CPE acquisition. Individual risk factors must be considered jointly with the local epidemiology of these microorganisms in healthcare institutions. Overall, these infections have a high associated mortality. Mortality is influenced by host factors (e.g., age, comorbidity and immune deficiency), infection-related variables (e.g., type and severity of the infection) and treatment-related factors such as the delay in the initiation of appropriate antimicrobial therapy and the use or monotherapy or combined antimicrobial therapy. Gaining knowledge concerning the epidemiology, clinical features and prognostic features of CPE infection could be useful for improving infection prevention and for the management of patients with infections caused by these microorganisms.

    2013-01-01

    Objectives: The purpose of this study was to determine the incidence and clinical symptoms associated with sharp mandibular bone irregularities (SMBI) after lower third molar extraction and to identify possible risk factors for this complication. Study Design: A mixed study design was used. A retrospective cohort study of 1432 lower third molar extractions was done to determine the incidence of SMBI and a retrospective case-control study was done to determine potential demographic and etiologic factors by comparing those patients with postoperative SMBI with controls. Results: Twelve SMBI were found (0.84%). Age was the most important risk factor for this complication. The operated side and the presence of an associated radiolucent image were also significantly related to the development of mandibular bone irregularities. The depth of impaction of the tooth might also be an important factor since erupted or nearly erupted third molars were more frequent in the SMBI group. Conclusions: SMBI are a rare postoperative complication after lower third molar removal. Older patients having left side lower third molars removed are more likely to develop this problem. The treatment should be the removal of the irregularity when the patient is symptomatic. Key words:Third molar, postoperative complication, bone irregularities, age. PMID:23524429

    Purpose Evaluate the potential Drug–Drug Interactions (pDDI) found in prescription orders of adult Intensive Care Unit (ICU) of a Brazilian public health system hospital; quantify and qualify the pDDI regarding their severity and risks to the critical patient, using the database from Micromedex®. Methods Prospective study (January–December of 2011) collecting and evaluating 369 prescription orders (convenient sampling), one per patient. Results During the study 1844 pDDIs were identified and distributed in 405 pairs (medication A × medication B combination). There was an average of 5.00 ± 5.06 pDDIs per prescription order, the most prevalent being moderate and important interactions, present in 74% and 67% of prescription orders, respectively. In total, there were 9 contraindicated, 129 important and 204 moderate pDDIs. Among them 52 had as management recommendation to “avoid concomitant use” or “suspension of medication”, while 306 had as recommendation “continuous and adequate monitoring”. Conclusion The high number of pDDIs found in the study combined with the evaluation of the clinical relevancy of the most frequent pDDIs in the ICU shows that moderate and important interactions are highly incident. As the majority of them demand monitoring and adequate management, being aware of these interactions is major information for the safe and individualized risk management. PMID:27134536

    Background Chronic respiratory disease-associated pulmonary hypertension (PH) is an important subtype of PH, which lacks clinical epidemiological data in China. Methods Six hundred and ninety three patients hospitalized from 2010 to 2013 were classified by echocardiography according to pulmonary arterial systolic pressure (PASP): mild (36≤ PASP 20 mm) were associated with moderate-to-severe PH, while RV [odds ratio (OR) =3.53, 95% CI, 2.17–5.74], NT-proBNP (OR=2.44, 95% CI, 1.51–3.95), HCT (OR=1.03, 95% CI, 1.00–1.07) and PaCO2 (OR=1.01, 95% CI, 1.00–1.03) were independent risk factors. Conclusions PH related to respiratory diseases is mostly mild to moderate, and the severity is associated with the category of respiratory disease. Increased HCT can be an independent risk factor for PH related to chronic respiratory diseases. PMID:27076929

  4. Short sleep is a questionable risk factor for obesity and related disorders: statistical versus clinical significance.

    Horne, Jim

    2008-03-01

    Habitually insufficient sleep could contribute towards obesity, metabolic syndrome, etc., via sleepiness-related inactivity and excess energy intake; more controversially, through more direct physiological changes. Epidemiological studies in adult/children point to small clinical risk only in very short (around 5h in adults), or long sleepers, developing over many years, involving hundreds of hours of 'too little' or 'too much' sleep. Although acute 4h/day sleep restriction leads to glucose intolerance and incipient metabolic syndrome, this is too little sleep and cannot be sustained beyond a few days. Few obese adults/children are short sleepers, and few short sleeping adults/children are obese or suffer obesity-related disorders. For adults, about 7h uninterrupted daily sleep is 'healthy'. Extending sleep, even with hypnotics, to lose weight, may take years, compared with the rapidity of utilising extra sleep time to exercise and evaluate one's diet. The real health risk of inadequate sleep comes from a sleepiness-related accident.

  5. Hospital-associated funguria: analysis of risk factors, clinical presentation and outcome

    2001-12-01

    Full Text Available Fungal urinary tract infections are an increasing problem in hospitalized patients. Funguria may be a result of contamination of the urine specimen, colonization of the urinary tract, or may be indicative of true invasive infection. In this study, we report the risk factors, clinical features, treatments and outcome in a group of 68 hospitalized patients (adults and children with fungal isolates recovered from 103 urinary samples. Underlying medical conditions were present in most patients. In the pediatric group, urinary tract abnormalities (86% and prematurity (19% accounted for the majority of the cases. Diabetes mellitus (28%, nephrolithiasis, and benign prostatic hyperplasia were the most common diseases in adults. Indwelling urethral catheters were noted in 38% of the pediatric patients and in 43% of adults during hospitalization. Candida albicans strains were responsible for 97% and 75% of positive cultures in children and adults, respectively. Symptoms such as fever, dysuria, frequency and flank pain were generally absent in both groups. Fluconazole was the most frequent antifungal utilized (61% in children and ketoconazole in the adult group (42%. Removing the urinary catheter was attempted in 6 pediatric patients (29% and in only 8 adults (17%. One patient (4% in the pediatric group died compared to 10 in the adult group (21%, p=0.04. Successful diagnosis and treatment of funguria depends on a clear understanding of the risk factors and awareness of fungal epidemiology.

  6. Epidemiology, Risk Factors, and Clinical Features of Intracerebral Hemorrhage: An Update

    An, Sang Joon; Kim, Tae Jung; Yoon, Byung-Woo

    2017-01-01

    Intracerebral hemorrhage (ICH) is the second most common subtype of stroke and a critical disease usually leading to severe disability or death. ICH is more common in Asians, advanced age, male sex, and low- and middle-income countries. The case fatality rate of ICH is high (40% at 1 month and 54% at 1 year), and only 12% to 39% of survivors can achieve long-term functional independence. Risk factors of ICH are hypertension, current smoking, excessive alcohol consumption, hypocholesterolemia, and drugs. Old age, male sex, Asian ethnicity, chronic kidney disease, cerebral amyloid angiopathy (CAA), and cerebral microbleeds (CMBs) increase the risk of ICH. Clinical presentation varies according to the size and location of hematoma, and intraventricular extension of hemorrhage. Patients with CAA-related ICH frequently have concomitant cognitive impairment. Anticoagulation related ICH is increasing recently as the elderly population who have atrial fibrillation is increasing. As non-vitamin K antagonist oral anticoagulants (NOACs) are currently replacing warfarin, management of NOAC-associated ICH has become an emerging issue. PMID:28178408

  7. Approval of high-risk medical devices in the US: implications for clinical cardiology.

    Rome, Benjamin N; Kramer, Daniel B; Kesselheim, Aaron S

    2014-01-01

    Since 1976, the US Food and Drug Administration (FDA) has used the premarket approval (PMA) process to approve high-risk medical devices, including implantable cardioverter defibrillators (ICDs), coronary stents, and artificial heart valves. The PMA process is widely viewed as a rigorous evaluation of device safety and effectiveness, though recent recalls-most notably related to underperforming ICD leads-have raised concerns about whether physicians and patients should sometimes be more wary about devices approved via this pathway. The FDA must utilize a "least burdensome" approach to approve new medical devices, and many widely used device models have been approved as supplements to existing PMA-approved devices with limited clinical testing. A recent Supreme Court ruling has made it difficult for patients harmed by unsafe PMA-approved devices to seek damages in court. Cardiologists who utilize high-risk medical devices should be aware that FDA approval of new devices relies on variable levels of evidence and does not necessarily indicate improved effectiveness over existing models. Clinician and patient engagement in postmarket surveillance and comparative effectiveness research remains imperative.

    Reddy, Jagadesh C.; Murthy, Somasheila I.; Reddy, Ashok K.; Garg, Prashant

    2015-01-01

    Purpose: The aim was to analyze demographics, risk factors, pathogenic organisms, and clinical outcome in cases with microbiologically proven bacterial or fungal scleritis. Materials and Methods: Retrospective review of all the medical records of patients with microbiologically proven infectious scleritis examined from March 2005 to December 2009 in the cornea services of L. V. Prasad Eye Institute, Hyderabad, India was done. Results: Forty-two eyes of 42 patients were included in this study. The mean age at presentation was 48.52 ± 14.10 years (range: 12-70). Surgery was the major risk factor seen in 24 eyes (58.5%). Scleral infection was noted after vitreoretinal surgery (with scleral buckle) in 15 eyes, cataract surgery in 3 eyes, pterygium surgery in 3 eyes, corneoscleral tear repair and scleral buckle surgery in 3 eyes. Sixteen eyes (39%) were on systemic or topical steroids at the time of presentation. History of injury was noted in 9 eyes (22%) and diabetes mellitus in 7 patients (17%). Associated keratitis was noted in 9 eyes (21.4%). The scleral abscess was unifocal in 33 eyes (78.5%), multifocal in 6 eyes (14.2%) and diffuse in 3 eyes (7.14%). The final follow-up ranged from 24 days to 37 months. The final visual acuity was better in 18 eyes (42.8%), stable in 13 (30.9%), and deteriorated in 7 eyes (16.6%). Recurrence was seen in 4 eyes (9.5%). Conclusions: Surgery is a major risk factor for infectious scleritis in our series. Fungus was the most common organism isolated. Thorough debridement and intensive use of medications have improved the outcome. PMID:25949079

    2013-10-01

    Full Text Available Age related macular degeneration (AMD is a leadi ng cause of irreversible blindness among the elderly worldwide affecting 30 - 50 million individuals. AMD is more common in developed world. AMD is characterized by central visual loss. Advanced AMD can be classified in broadly into two types: dry and wet fo rm. Several clear risk factors for the development and progression of age related macular degeneration have been established are advancing age, genetic factors, history of smoking ,white race, obesity, high dietary intake of vegetable fat, low dietary inta ke of antioxidants and zinc. This prospective non - interventional study was conducted from February 2011 to October 2012 in the Regional Institute of Ophthalmology, Hamidia Hospital, Bhopal, included patients who attended the eye OPD, retina clinic and eye ward and were diagnosed as a case of AMD. Present study included 174 patients out of which patients 79(45.39% were above the age of 70 years, with 51 (29.31% patients between 61 - 70 years and 44 cases (25.28% in the sixth decade. Male: female ratio was 0 .75: 1. 21 (12.06% patients have a positive family history of AMD. Most common risk factor identified in our study was chronic sun exposure (49.42% followed by hypertension in 41.8% patients. 25.26% cases gave history of smoking and raised serum cholest erol levels were seen in 14.28% cases. History of alcoholism was positive in 19.54% patients. Of the 174 cases in our present study 90 patients (51.72% were hypermetropic. Conclusion: Age related macular degeneration is a disease of elderly with risk fact ors, most of them are preventable. If timely proper measures are taken, a major cause of blindness can be prevented in elderly age group.

    The biopharmaceutics risk assessment roadmap (BioRAM) optimizes drug product development and performance by using therapy-driven target drug delivery profiles as a framework to achieve the desired therapeutic outcome. Hence, clinical relevance is directly built into early formulation development. Biopharmaceutics tools are used to identify and address potential challenges to optimize the drug product for patient benefit. For illustration, BioRAM is applied to four relatively common therapy-driven drug delivery scenarios: rapid therapeutic onset, multiphasic delivery, delayed therapeutic onset, and maintenance of target exposure. BioRAM considers the therapeutic target with the drug substance characteristics and enables collection of critical knowledge for development of a dosage form that can perform consistently for meeting the patient's needs. Accordingly, the key factors are identified and in vitro, in vivo, and in silico modeling and simulation techniques are used to elucidate the optimal drug delivery rate and pattern. BioRAM enables (1) feasibility assessment for the dosage form, (2) development and conduct of appropriate "learning and confirming" studies, (3) transparency in decision-making, (4) assurance of drug product quality during lifecycle management, and (5) development of robust linkages between the desired clinical outcome and the necessary product quality attributes for inclusion in the quality target product profile.

    Silva, Esther Pereira da; Lima, Roberto Teixeira de; Osório, Mônica Maria

    2016-09-01

    This study aimed to analyze the impact of educational strategies developed in low-risk prenatal care on obstetric outcomes from a systematic literature review. This review consulted databases PubMed, Medline, SciELO and Lilacs, analyzing randomized clinical trials with the following birth outcomes: birth weight, prematurity and breastfeeding, using the following combination of keywords: pre-natal, antenatal visits, education, health education, pregnancy outcomes, birth weight, prematurity, breastfeeding and randomized clinical trial. Nine studies were included following quality evaluation. Actions prove to be more effective when extended to the postpartum period. Most of them occurred during home visits and had a positive impact on breastfeeding and birth weight. The establishment of groups of pregnant women contributed to lower prevalence of prematurity. Breastfeeding was found to be the outcome most sensitive to educational strategies. Educational practices during the prenatal period contributed to favorable obstetric outcomes as they minimized pregnant women concerns and anxiety during the pregnancy process, preparing them for childbirth and postpartum, and should be incorporated into health services' work process.

    reported previous significant suicidality at baseline. No sociodemographic and clinical variables at baseline were predictive of suicidal status at the end of the 10-year follow-up.Conclusion: Schizophrenia is a complex neurobehavioral disorder that appears to be closely associated with suicidal behavior. Adequate assessment and management of suicidality needs to be a continual process, even in patients who respond well to treatment.Keywords: schizophrenia, suicide risk, prevention 

  13. Evaluation of clinical and laboratory markers of cardiometabolic risk in overweight and obese children and adolescents

    Heloísa Marcelina da Cunha Palhares

    Full Text Available OBJECTIVE: This study analyzed the frequency of cardiometabolic risk markers and metabolic syndrome occurrence in overweight and obese children and adolescents. METHODS: The participants included 161 overweight (n=65 and obese (n=96 individuals aged between 5 and 19 years. Clinical markers were assessed (body mass index, body fat percentage, waist circumference, acanthosis, systolic and diastolic blood pressures, laboratory parameters [glucose, insulin, cholesterol (total and fractions and triglyceride levels and homeostasis model assessment of insulin resistance (HOMA-IR index] and leptin and adiponectin levels. The frequency of changes, odds ratios and correlations among markers were determined. Metabolic syndrome was assessed according to International Diabetes Federation criteria. RESULTS: A high frequency of acanthosis (51.6%; increased waist circumference (45.4%, systolic blood pressure / diastolic blood pressure (8.1% / 9.3%, glucose (10%, insulin (36.9% and HOMA-IR (44.3% values; and reduced high-density lipoprotein levels (47.2% were observed. Leptin levels were increased in 95% of obese and in 66% of overweight subjects. Adiponectin was decreased in 29.5% of obese and in 34% of overweight subjects. An odd ratio analysis revealed a greater probability of increased waist circumference (9.0, systolic blood pressure (4.1, triglyceride (2.3 and insulin (2.9 levels and HOMA-IR (3.0 in the obese group than in the overweight group. The clinical and laboratory parameters and leptin levels exhibited significant correlations, whereas adiponectin was negatively correlated with systolic blood pressure. The occurrence rate of metabolic syndrome was 13.6%. CONCLUSIONS: The high frequency of changes in clinical, laboratory and adipokine markers indicates the need for early interventions aimed at preventing cardiometabolic complications in adulthood.

    Full Text Available OBJECTIVE: to test the clinical utility of an early amplitude-integrated electroencephalography (aEEG to predict short-term neurological outcome in term newborns at risk of neurology injury. METHODS: this was a prospective, descriptive study. The inclusion criteria were neonatal encephalopathy, neurologic disturbances, and severe respiratory distress syndrome. Sensitivity, specificity, positive and negative predictive values, and likelihood ratio (LR were calculated. Clinical and demographic data were analyzed. Neurological outcome was defined as the sum of clinical, electroimaging, and neuroimaging findings. RESULTS: ten of the 21 monitored infants (48% presented altered short-term neurologic outcome. The aEEG had 90% sensitivity, 82% specificity, 82% positive predictive value, and 90% negative predictive value. The positive LR was 4.95, and the negative LR was 0.12. In three of 12 (25% encephalopathic infants, the aEEG allowed for a better definition of the severity of their condition. Seizures were detected in eight infants (38%, all subclinical at baseline, and none had a normal aEEG background pattern. The status of three infants (43% evolved and required two or more drugs for treatment. CONCLUSIONS: in infants with encephalopathy or other severe illness, aEEG disturbances occur frequently. aEEG provided a better classification of the severity of encephalopathy, detected early subclinical seizures, and allowed for monitoring of the response to treatment. aEEG was a useful tool at the neonatal intensive care unit for predicting poor short-term neurological outcomes for all sick newborn.

    1995-01-01

    An initial screening investigation of 1681 Swedish urban adults aged 31-40 years with untreated periodontitis showed that 17.2% (289) had at least one site with probing depth > or = 5 mm. The 289 subjects were offered a complete clinical examination and treatment. 144 subjects, 85 men and 59 women, agreed to participate and 145 were non-responding subjects and used as a drop out sample. The results from the screening data showed that the attendants had poorer oral hygiene status and more severe periodontitis than the drop out subjects. The present report describes clinical data of this representative sample with adult periodontitis. Clinical indices were recorded and bone height (BH%) for all teeth was measured with a computer digitizing system. In the 144 attendants, Plaque Index was > 1 in 56.2%, Calculus Index was > 1 in 57.0%, Gingival Index was > 1 in 97.2% and bleeding on probing was found in 89.1% of the sites. 11.1% of the subjects had 1-3 teeth with probing depth > or = 5 mm, 59.0% 4-10 teeth, 25.7% 11-20 teeth and 4.2% > 20 teeth. 47.9% of the subjects had mean BH% less than 80. 45.1% of the subjects had at least one site with an intrabony defect, of which 20% had 3-4 sites and 27.7% > or = 5 sites. It is concluded that advanced generalized periodontitis exists in a limited number of 31-40 year-olds in Sweden. Specific risk factors may be involved in the pathogenesis of the disease.

  16. Minimizing repolarization-related proarrhythmic risk in drug development and clinical practice.

    Farkas, Attila S; Nattel, Stanley

    2010-03-26

    Proarrhythmia, the development of new or worse arrhythmias in response to drug therapy, is a major limitation to the development and use of new drugs. There are different types of drug-induced proarrhythmia, including long-QT syndrome (LQTS), short-QT syndrome and proarrhythmia related to Na+-channel blockade/conduction impairment. By far the most important form of proarrhythmia at present is drug-induced LQTS and its associated characteristic tachyarrhythmia, torsades de pointes (TdP). TdP arises when cellular action potentials (APs) are excessively prolonged, leading to arrhythmogenic afterdepolarizations, especially early afterdepolarizations (EADs), which trigger complex re-entry in a substrate involving increased transmural dispersion of repolarization. In vitro screening, increasingly involving high-throughput assays, is used to assess potential candidate molecules and eliminate potentially problematic structures at an early stage of development. The most commonly used screening assays assess drug block of the K+ current carried by human ether-à-go-go (hERG) subunits, corresponding to the rapid delayed-rectifier K+ channel, the overwhelmingly most common target of TdP-inducing drugs. In addition, the effects of drugs on AP duration or the in vivo equivalent, QT interval, are often assessed in animal models. Methods available for repolarization-related proarrhythmic risk assessment include in vitro (Langendorff-perfused rabbit or guinea pig hearts) and in vivo models (such as alpha-adrenoceptor-stimulated rabbits, rabbits with reduced repolarization reserve due to block of slow delayed-rectifier current, animals with chronic atrioventricular block or animals with cardiac remodelling caused by congestive heart failure). In silico modelling may be helpful for molecular design of non-hERG blocking candidates and for optimization of compound selection (at the molecular and pharmacological profile levels). Finally, clinical evaluation of effects on

    Studies show that individuals with psychotic illnesses and their families want information about psychosis risks for other relatives. However, deriving accurate numeric probabilities for psychosis risk is challenging, and people have difficulty interpreting probabilistic information; thus, some have suggested that clinicians should use risk descriptors, such as "moderate" or "quite high", rather than numbers. Little is known about how individuals with psychosis and their family members use quantitative and qualitative descriptors of risk in the specific context of chance for an individual to develop psychosis. We explored numeric and descriptive estimations of psychosis risk among individuals with psychotic disorders and unaffected first-degree relatives. In an online survey, respondents numerically and descriptively estimated risk for an individual to develop psychosis in scenarios where they had: A) no affected family members; and B) an affected sibling. Participants comprised 219 affected individuals and 211 first-degree relatives participated. Affected individuals estimated significantly higher risks than relatives. Participants attributed all descriptors between "very low" and "very high" to probabilities of 1%, 10%, 25% and 50%+. For a given numeric probability, different risk descriptors were attributed in different scenarios. Clinically, brief interventions around risk (using either probabilities or descriptors alone) are vulnerable to miscommunication and potentially negative consequences-interventions around risk are best suited to in-depth discussion.

Polypharmacy is common in patients receiving omeprazole. Drug toxicity and treatment failure resulting from inappropriate combination therapy with omeprazole have been reported sporadically. Systematic review has not been available to address the pharmacokinetic drug-drug interaction (DDI profile of omeprazole with adverse consequences, the factors determining the degree of DDI between omeprazole and comedication, and the corresponding clinical risk management.Methods: Literature was identified by performing a PubMed search covering the period from January 1988 to March 2013. The full text of each article was critically reviewed, and data interpretation was performed.Results: Omeprazole has actual adverse influences on the pharmacokinetics of medications such as diazepam, carbamazepine, clozapine, indinavir, nelfinavir, atazanavir, rilpivirine, methotrexate, tacrolimus, mycophenolate mofetil, clopidogrel, digoxin, itraconazole, posaconazole, and oral iron supplementation. Meanwhile, low efficacy of omeprazole treatment would be anticipated, as omeprazole elimination could be significantly induced by comedicated efavirenz and herb medicines such as St John's wort, Ginkgo biloba, and yin zhi huang. The mechanism for DDI involves induction or inhibition of cytochrome P450, inhibition of P-glycoprotein or breast

    The role of environmental risk factors in clinical malaria has been studied mainly in Africa and Asia, few investigations have been carried out in Latin America. Field observations in northern coastal Peru, where the prevalence of malaria is high during the agricultural season, suggested that the risk of disease varied according to the characteristics of the house and the house environment. Environmental determinants of the risk of clinical malaria were therefore investigated through a case-control study: 323 clinical cases of malaria, recruited through community-based active case-finding, and 969 age-, sex- and village-matched controls were recruited into the study over a period of 12 months ending June 1997. Residual spraying of houses in the previous 6 months, living more than 100 m from a canal, a level of education equal to primary school or above and working in agriculture conferred significant protection from the risk of developing clinical malaria. The presence of spaces between the wall and roof in the subject's bedroom (eaves) and a house aged > 4 years statistically significantly increased the risk of disease. Based on these results we discuss possible control measures for malaria in this area of the country.

    Multifaceted, sustained efforts are needed to reduce early pregnancy and sexually transmitted diseases among high-risk adolescents. An important area for research is testing youth development interventions offered through clinic settings, where access to high-risk adolescents is plentiful and few efforts have rigorously evaluated a dual approach of building protective factors while addressing risk. This article presents findings from a pilot study of Prime Time, a clinic-based youth development intervention to reduce sexual risk behaviors among girls at risk for early pregnancy. Girls aged 13 to 17 years meeting specified risk criteria were assigned to Prime Time treatment groups. The Prime Time intervention included a combination of case management services and peer leadership groups. Participants completed self-report surveys at baseline, 12 and 18 months following enrollment. At 12 months, the intervention group reported significantly fewer sexual partners than the control group. At 18 months, the intervention group reported significantly more consistent condom use with trends toward more consistent hormonal and dual method use. Dose-response analyses suggested that relatively high levels of exposure to a youth development intervention were needed to change contraceptive use behaviors among adolescents at risk for early pregnancy. Given promising findings, further testing of the Prime Time intervention is warranted.

    2014-11-01

    Full Text Available Introduction: It is uncertain if plasma HIV-1 tropism is an independent predictor of short-term risk of clinical progression / death, in addition to the CD4 count and HIV RNA level. We conducted a nested case-control study within EuroSIDA to assess this question amongst people with current HIV RNA level >1000 copies/mL, including both people on ART and those ART naïve. Methods: People with an AIDS diagnosis or who died from any causes for whom there was a stored plasma sample with HIV-1 RNA (VL≥1,000 copies/mL available in the time window of 3–12 months prior to the event were identified. At least one control was selected for each case matched for age, VL and HCV status at the time of sampling. Controls were event-free after a matched duration of time from the date of sampling. Plasma HIV tropism was estimated using 454 and population sequencing (PS. Non-R5 HIV was defined as: (a ≥2% of sequences with a Geno2Pheno (G2P FPR≤3.75% by 454, and (b a G2P FPR≤10% by PS. We also compared CD4 slopes over the 12 months following the date of sampling using a linear mixed model with random intercept according to HIV tropism and ART status. Results: The study included 266 subjects, 100 cases and 166 controls, with sample taken on average in 2006; 23% and 24% had non-R5 HIV by 454 and PS respectively. There were 19% women, 25% MSM, 92% Caucasians, 22% HCV+. At the time of sampling, 26% were ART-naïve, 25% had started but were off ART and 49% were receiving ART. The median age, CD4 and viral load was 41 years, 350 cells/mm3 and 4.81 log c/mL, respectively. Baseline characteristics were well balanced by tropism. Factors independently associated with clinical progression or death were female gender (OR=2.12; 95% CI=1.04, 4.36; p=0.038, CD4+ count (OR=0.90 per 100 cells/mm3 higher; 95% CI 0.80, 1.00; p=0.058, being on ART (OR=2.72; 95% CI 1.15, 6.41; p=0.022 and calendar year of sample (OR=0.84 per more recent year; 95% CI=0.77, 0.91; p<0

  3. Real-World Assessment of Clinical Outcomes in Patients with Lower-Risk Myelofibrosis Receiving Treatment with Ruxolitinib

    Full Text Available Few trial-based assessments of ruxolitinib in patients with lower-risk myelofibrosis (MF have been conducted, and no studies have made such assessments in a real-world population. We assessed changes in spleen size and constitutional symptoms during ruxolitinib treatment using a retrospective, observational review of anonymized US medical record data of patients diagnosed with IPSS low-risk (n=25 or intermediate-1-risk (n=83 MF. The majority of patients were male (low risk, 60%; intermediate-1 risk, 69%. Most patients (92% and 77% were still receiving ruxolitinib at the medical record abstraction date (median observation/exposure time, 8 months. The proportion of patients with moderate or severe palpable splenomegaly (≥10 cm decreased from diagnosis (56% to best response (12%. Fatigue was reported in 47% of patients and was the most common constitutional symptom. For most symptoms in both risk groups, shifts in the distribution of severity from more to less severe from diagnosis to best response were observed. Both patients with low-risk and intermediate-1-risk MF experienced a substantial decrease in spleen size with ruxolitinib treatment in real-world settings. For most symptoms examined, there were distinct improvements in the distribution of severity during ruxolitinib treatment. These findings suggest that patients with lower-risk MF may benefit clinically from ruxolitinib treatment.

    Increased media attention to post-deployment violence highlights the need to develop effective models to guide risk assessment among military Veterans. Ideally, a method would help identify which Veterans are most at risk for violence so that it can be determined what could be done to prevent violent behavior. This article suggests how empirical approaches to risk assessment used successfully in civilian populations can be applied to Veterans. A review was conducted of the scientific literature on Veteran populations regarding factors related to interpersonal violence generally and to domestic violence specifically. A checklist was then generated of empirically-supported risk factors for clinicians to consider in practice. To conceptualize how these known risk factors relate to a Veteran's violence potential, risk assessment scholarship was utilized to develop an evidence-based method to guide mental health professionals. The goals of this approach are to integrate science into practice, overcome logistical barriers, and permit more effective assessment, monitoring, and management of violence risk for clinicians working with Veterans, both in Department of Veteran Affairs settings and in the broader community. Research is needed to test the predictive validity of risk assessment models. Ultimately, the use of a systematic, empirical framework could lead to improved clinical decision-making in the area of risk assessment and potentially help prevent violence among Veterans.

  5. Three-tiered risk stratification model to predict progression in Barrett's esophagus using epigenetic and clinical features.

    Fumiaki Sato

    Full Text Available Barrett's esophagus predisposes to esophageal adenocarcinoma. However, the value of endoscopic surveillance in Barrett's esophagus has been debated because of the low incidence of esophageal adenocarcinoma in Barrett's esophagus. Moreover, high inter-observer and sampling-dependent variation in the histologic staging of dysplasia make clinical risk assessment problematic. In this study, we developed a 3-tiered risk stratification strategy, based on systematically selected epigenetic and clinical parameters, to improve Barrett's esophagus surveillance efficiency.We defined high-grade dysplasia as endpoint of progression, and Barrett's esophagus progressor patients as Barrett's esophagus patients with either no dysplasia or low-grade dysplasia who later developed high-grade dysplasia or esophageal adenocarcinoma. We analyzed 4 epigenetic and 3 clinical parameters in 118 Barrett's esophagus tissues obtained from 35 progressor and 27 non-progressor Barrett's esophagus patients from Baltimore Veterans Affairs Maryland Health Care Systems and Mayo Clinic. Based on 2-year and 4-year prediction models using linear discriminant analysis (area under the receiver-operator characteristic (ROC curve: 0.8386 and 0.7910, respectively, Barrett's esophagus specimens were stratified into high-risk (HR, intermediate-risk (IR, or low-risk (LR groups. This 3-tiered stratification method retained both the high specificity of the 2-year model and the high sensitivity of the 4-year model. Progression-free survivals differed significantly among the 3 risk groups, with p = 0.0022 (HR vs. IR and p<0.0001 (HR or IR vs. LR. Incremental value analyses demonstrated that the number of methylated genes contributed most influentially to prediction accuracy.This 3-tiered risk stratification strategy has the potential to exert a profound impact on Barrett's esophagus surveillance accuracy and efficiency.

  6. Women up, men down: the clinical impact of replacing the Framingham Risk Score with the Reynolds Risk Score in the United States population.

    Matthew C Tattersall

    Full Text Available BACKGROUND: The Reynolds Risk Score (RRS is one alternative to the Framingham Risk Score (FRS for cardiovascular risk assessment. The Adult Treatment Panel III (ATP III integrated the FRS a decade ago, but with the anticipated release of ATP IV, it remains uncertain how and which risk models will be integrated into the recommendations. We sought to define the effects in the United States population of a transition from the FRS to the RRS for cardiovascular risk assessment. METHODS: Using the National Health and Nutrition Examination Surveys, we assessed FRS and RRS in 2,502 subjects representing approximately 53.6 Million (M men (ages 50-79 and women (ages 45-79, without cardiovascular disease or diabetes. We calculated the proportion reclassified by RRS and the subset whose LDL-C goal achievement changed. RESULTS: Compared to FRS, the RRS assigns a higher risk category to 13.9% of women and 9.1% of men while assigning a lower risk to 35.7% of men and 2% of women. Overall, 4.7% of women and 1.1% of men fail to meet newly intensified LDL-C goals using the RRS. Conversely, 10.5% of men and 0.6% of women now meet LDL-C goal using RRS when they had not by FRS. CONCLUSION: In the U.S. population the RRS assigns a new risk category for one in six women and four of nine men. In general, women increase while men decrease risk. In conclusion, adopting the RRS for the 53.6 million eligible U.S. adults would result in intensification of clinical management in 1.6 M additional women and 2.10 M fewer men.

  7. Neurological complications after neonatal bacteremia: the clinical characteristics, risk factors, and outcomes.

    Shih-Ming Chu

    Full Text Available BACKGROUND: Neonates with bacteremia are at risk of neurologic complications. Relevant information warrants further elucidation. STUDY DESIGN: This was a retrospective cohort study of neonates with bacteremia-related neurologic complications (BNCs in a tertiary-level neonatal intensive care unit (NICU. A systemic chart review was performed conducted to identify clinical characteristics and outcomes. A cohort of related conditions was constructed as the control group. Logistic regression analysis was used to identify independent risk factors for BNC. RESULTS: Of 1037 bacteremia episodes, 36 (3.5% had BNCs. Twenty-four cases of BNCs were related to meningitis, five were presumed meningitis, and seven occurred after septic shock. The most common causative pathogens were Group B streptococcus (41.7% and E. coli (16.7%. The major BNCs consisted of seizures (28, hydrocephalus (20, encephalomalacia (11, cerebral infarction (7, subdural empyema (6, ventriculitis (8, and abscess (4. Eight (22.8% neonates died and six (16.7% were discharged in critical condition when the family withdrew life-sustaining treatment. Among the 22 survivors, eight had neurologic sequelae upon discharge. After multivariate logistic regression analysis, neonates with meningitis caused by Group B streptococcus (adjusted odds ratio [OR]: 8.90, 95% confidence interval [CI]: 2.20-36.08; p = 0.002 and combined meningitis and septic shock (OR, 5.94; 95% CI: 1.53-23.15; p = 0.010 were independently associated with BNCs. CONCLUSIONS: Neonates with bacteremia-related neurologic complications are associated with adverse outcomes or sequelae. Better strategies aimed at early detection and reducing the emergence of neurologic complications and aggressive treatment of Group B streptococcus sepsis are needed in neonates with meningitis and septic shock.

  8. Incidence, clinical outcome, and risk stratification of ventilator-associated pneumonia-a prospective cohort study

    2005-01-01

    Full Text Available Context and Aim: Ventilator-associated pneumonia (VAP remains to be the commonest cause of hospital morbidity and mortality in spite of advances in diagnostic techniques and management. This project aims to study the various risk factors and the common microbial flora associated with VAP. It also evaluates the use of APACHEIII scores for prognostication. Study Design: A prospective cohort study was conducted over 1 year in medical critical care unit (CCU of a tertiary-care teaching hospital. Methods and Material: VAP was diagnosed using the clinical pulmonary infection score (CPIS of more than 6. The study cohort comprised 51 patients. All CCU patients requiring mechanical ventilation for more than 48 h formed the study group. Statistical Analysis Used: Univariate analysis, c2-test, and paired "t-test." Results: Twenty-four out of fifty-one cases developed VAP. These cases had an average APACHEIII score of more than 55 on admission to critical care unit (CCU. They needed prolonged mechanical ventilation and had lower PaO2/FiO2 ratio as compared with the remaining patients who did not develop VAP. Pseudomonas aeroginosa was the commonest and most lethal organism. The mortality in the VAP group was 37% and correlated very well with higher APACHEIII scores on admission. Conclusions: Longer duration of mechanical ventilation and the need of reintubation are associated with proportionate rise in the incidence of VAP. Deteriorating PaO2/FiO2 ratio correlated well with the onset of VAP. Higher APACHEIII scores on admission stratify the mortality risk.

  9. The validation and clinical implementation of BRCAplus: a comprehensive high-risk breast cancer diagnostic assay.

    Hansook Kim Chong

    Full Text Available Breast cancer is the most commonly diagnosed cancer in women, with 10% of disease attributed to hereditary factors. Although BRCA1 and BRCA2 account for a high percentage of hereditary cases, there are more than 25 susceptibility genes that differentially impact the risk for breast cancer. Traditionally, germline testing for breast cancer was performed by Sanger dideoxy terminator sequencing in a reflexive manner, beginning with BRCA1 and BRCA2. The introduction of next-generation sequencing (NGS has enabled the simultaneous testing of all genes implicated in breast cancer resulting in diagnostic labs offering large, comprehensive gene panels. However, some physicians prefer to only test for those genes in which established surveillance and treatment protocol exists. The NGS based BRCAplus test utilizes a custom tiled PCR based target enrichment design and bioinformatics pipeline coupled with array comparative genomic hybridization (aCGH to identify mutations in the six high-risk genes: BRCA1, BRCA2, PTEN, TP53, CDH1, and STK11. Validation of the assay with 250 previously characterized samples resulted in 100% detection of 3,025 known variants and analytical specificity of 99.99%. Analysis of the clinical performance of the first 3,000 BRCAplus samples referred for testing revealed an average coverage greater than 9,000X per target base pair resulting in excellent specificity and the sensitivity to detect low level mosaicism and allele-drop out. The unique design of the assay enabled the detection of pathogenic mutations missed by previous testing. With the abundance of NGS diagnostic tests being released, it is essential that clinicians understand the advantages and limitations of different test designs.

    Full Text Available Background and Aim: Differences in patient characteristics due to race or ethnicity may influence the incidence of difficult airway. Our purpose was to determine the incidence of difficult laryngoscopy and intubation, as well as the anatomical features and clinical risk factors that influence them, in the Indian population. Methods: In 330 adult patients receiving general anaesthesia with tracheal intubation, airway characteristics and clinical factors were determined and their association with difficult laryngoscopy (Cormack and Lehane grade 3 and 4 was analysed. Intubation Difficulty Scale score was used to identify degree of difficult laryngoscopy. Results: The incidence of difficult laryngoscopy and intubation was 9.7% and 4.5%, respectively. Univariate analysis showed that increasing age and weight, male gender, modified Mallampati class (MMC 3 and 4 in sitting and supine positions, inter-incisor distance (IID ≤3.5 cm, thyromental (TMD and sternomental distance, ratio of height and TMD, short neck, limited mandibular protrusion, decreased range of neck movement, history of snoring, receding mandible and cervical spondylosis were associated with difficult laryngoscopy. Multivariate analysis identified four variables that were independently associated with difficult laryngoscopy: MMC class 3 and 4, range of neck movement <80°, IID ≤ 3.5 cm and snoring. Conclusions: We found an incidence of 9.7% and 4.5% for difficult laryngoscopy and difficult intubation, respectively, in Indian patients with apparently normal airways. MMC class 3 and 4, range of neck movement <80°, IID ≤ 3.5 cm and snoring were independently related to difficult laryngoscopy. There was a high incidence (48.5% of minor difficulty in intubation.

  11. Noninvasive mechanical ventilation in high-risk pulmonary infections: a clinical review

    Antonio M. Esquinas

    2014-12-01

    Full Text Available The aim of this article was to review the role of noninvasive ventilation (NIV in acute pulmonary infectious diseases, such as severe acute respiratory syndrome (SARS, H1N1 and tuberculosis, and to assess the risk of disease transmission with the use of NIV from patients to healthcare workers. We performed a clinical review by searching Medline and EMBASE. These databases were searched for articles on ‘‘clinical trials’’ and ‘‘randomised controlled trials’’. The keywords selected were non-invasive ventilation pulmonary infections, influenza-A (H1N1, SARS and tuberculosis. These terms were cross-referenced with the following keywords: health care workers, airborne infections, complications, intensive care unit and pandemic. The members of the International NIV Network examined the major results regarding NIV applications and SARS, H1N1 and tuberculosis. Cross-referencing mechanical ventilation with SARS yielded 76 studies, of which 10 studies involved the use of NIV and five were ultimately selected for inclusion in this review. Cross-referencing with H1N1 yielded 275 studies, of which 27 involved NIV. Of these, 22 were selected for review. Cross-referencing with tuberculosis yielded 285 studies, of which 15 involved NIV and from these seven were selected. In total 34 studies were selected for this review. NIV, when applied early in selected patients with SARS, H1N1 and acute pulmonary tuberculosis infections, can reverse respiratory failure. There are only a few reports of infectious disease transmission among healthcare workers.

  13. Cardiovascular effects of dipeptidyl peptidase-4 inhibitors: from risk factors to clinical outcomes.

    Scheen, André J

    2013-05-01

    Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) are oral incretin-based glucose-lowering agents with proven efficacy and safety in the management of type 2 diabetes mellitus (T2DM). In addition, preclinical data and mechanistic studies suggest a possible additional non-glycemic beneficial action on blood vessels and the heart, via both glucagon-like peptide-1-dependent and glucagon-like peptide-1-independent effects. As a matter of fact, DPP-4 inhibitors improve several cardiovascular risk factors: they improve glucose control (mainly by reducing the risk of postprandial hyperglycemia) and are weight neutral; may lower blood pressure somewhat; improve postprandial (and even fasting) lipemia; reduce inflammatory markers; diminish oxidative stress; improve endothelial function; and reduce platelet aggregation in patients with T2DM. In addition, positive effects on the myocardium have been described in patients with ischemic heart disease. Results of post hoc analyses of phase 2/3 controlled trials suggest a possible cardioprotective effect with a trend (sometimes significant) toward lower incidence of major cardiovascular events with sitagliptin, vildagliptin, saxagliptin, linagliptin, or alogliptin compared with placebo or other active glucose-lowering agents. However, the definite relationship between DPP-4 inhibition and better cardiovascular outcomes remains to be proven. Major prospective clinical trials involving various DPP-4 inhibitors with predefined cardiovascular outcomes are under way in patients with T2DM and a high-risk cardiovascular profile: the Sitagliptin Cardiovascular Outcome Study (TECOS) on sitagliptin, the Saxagliptin Assessment of Vascular Outcomes Recorded in Patients With Diabetes Mellitus-Thrombolysis in Myocardial Infarction (SAVOR-TIMI) 53 trial on saxagliptin, the Cardiovascular Outcomes Study of Alogliptin in Subjects With Type 2 Diabetes and Acute Coronary Syndrome (EXAMINE) trial on alogliptin, and the Cardiovascular Outcome

    Full Text Available The purpose of the present work was to study the clinical features and risk factors of tardive dyskinesia among     the     schizophrenia     patients     who     durably     receive     the     antipsychotic     therapy. 180 of the 18 to 65 age bracket schizophrenia patients, who were treated in a residential psychiatric treatment facility, were examined with the use of the Positive and Negative Syndrome Scale (PANSS, Abnormal Involuntary Movement Scale (AIMS, and the basic chart of formalized sociodemographic and clinico-dynamic features developed at the Tomsk Mental Health Research Institute. The acquired data were processed by the Mann–Whitney U-Test and χ2. The average age of the tardive dyskinesia patients  turned out to be conclusively older than that of the patients without this derangement. People who have tardive dyskinesia statistically often happen to be single in comparison with other variants of marital status. It was found out that women happen to have tardive dyskinesia more often, which allows us to see the female gender as a risk factor. The tardive dyskinesia patients had certain negative symptoms. The patients were arranged into groups according to the prepotency of symptom-complexes over the subgroups: with orofacial, thoracolumbar and combined tardive dyskinesia. The average age of the orofacial dyskinesia patients turned out to be conclusively older than that of the patients without tardive dyskinesia. The negative symptoms level in the subgroup was conclusively higher than among those without tardive dyskinesia. The average age of the thoracolumbar dyskinesia patients was conclusively older than that of the patients without tardive dyskinesia. The average age of the combined dyskinesia patients was conclusively older than the patients without the tardive dyskinesia. The patients having schizophrenia for longer than 10 years prevailed in the combined dyskinesia group. Such characteristics as education

    Abstract This study aimed to summarize the effects of noninvasive prenatal testing (NIPT) on aneuploidy among high-risk participants in Tangshan Maternal and Children Health Hospital. NIPT or invasive prenatal diagnosis was recommended to patients with a high risk of fetal aneuploidy from February 2013 to February 2014. Patients who exhibited eligibility and applied for NIPT from January 2012 to January 2013 were included in a comparison group. The rates of patients who underwent invasive testing, declined to undergo further testing, and manifested trisomies 21, 18, and 13 were compared between two groups. Follow-up data were obtained from the participants who underwent NIPT from 2013 to 2014. A total of 7223 patients (3018 and 4205 individuals before and after NIPT) were eligible for analysis. After NIPT was introduced in 2013 to 2014, 727 patients (17.3%) underwent invasive testing, 2828 preferred NIPT (67.3%), and 650 declined to undergo further testing (15.5%). A total of 34 cases of trisomies 21, 18, and 13 (0.8%) were found. In 2012 to 2013, 565 patients (18.7%) underwent invasive testing and 2453 declined to undergo further testing (81.3%). A total of 7 cases of trisomies 21, 18, and 13 were documented (0.2%). Of these cases, 24 were found from NIPT and 10 cases were found from invasive testing. The number of participants who declined to undergo further testing significantly decreased after NIPT was introduced (81.3% vs. 15.5%, P < 0.001). The sensitivity and specificity of NIPT for trisomies 21, 18, and 13 were 100% and 99.9%, respectively. The detection rates of NIPT for trisomies 21, 18, and 13 also significantly increased (0.2% vs. 0.8%, P < 0.001). By contrast, the overall rates of invasive testing remained unchanged (18.7% vs. 17.3%, P = 0.12). The positive predictive values of NIPT for trisomies 21, 18, and 13 were 100%, 83.3%, and 50.0%, respectively. The false positive rates of NIPT were 0% and 0.04%. With NIPT implementation in clinical

We exposed participants aged 5 to 17 years with psychosis n=22, at clinical high risk (CHR for psychosis n=29, and healthy controls n=17 to an auditory tone repeated 450 times and measured N100 adaptation (mean amplitude during first 150 tones − mean amplitude during last 150 tones. N100 adaptation was reduced in CHR and psychosis, particularly among participants <13 years old. Initial N100 blunting partially accounted for differences. Decreased change in the N100 amplitude with tone repetition may be a useful marker of defects in neuroplastic mechanisms measurable early in life.

Germline mutations in the APC gene were initially identified as responsible for FAP, and later, several studies have also implicated the MUTYH gene as responsible for this disease, usually referred to as MUTYH-associated polyposis (MAP. FAP and MAP are characterized by the early onset of multiple adenomatous colorectal polyps, a high lifetime risk of colorectal cancer (CRC, and in some patients the development of extracolonic manifestations. The goal of colorectal management in these patients is to prevent CRC mortality through endoscopic and surgical approaches. Individuals with FAP and their relatives should receive appropriate genetic counseling and join surveillance programs when indicated. This review is focused on the description of the main clinical and genetic aspects of FAP associated with germline APC mutations and MAP.

    2014-01-01

    INTRODUCTION: It is uncertain if plasma HIV-1 tropism is an independent predictor of short-term risk of clinical progression / death, in addition to the CD4 count and HIV RNA level. We conducted a nested case-control study within EuroSIDA to assess this question amongst people with current HIV RNA...... level >1000 copies/mL, including both people on ART and those ART naïve. METHODS: People with an AIDS diagnosis or who died from any causes for whom there was a stored plasma sample with HIV-1 RNA (VL)≥1,000 copies/mL available in the time window of 3-12 months prior to the event were identified....... At least one control was selected for each case matched for age, VL and HCV status at the time of sampling. Controls were event-free after a matched duration of time from the date of sampling. Plasma HIV tropism was estimated using 454 and population sequencing (PS). Non-R5 HIV was defined as: (a) ≥2...

  5. Clinical study on magnetic resonance imaging of lacunar infarcts and cerebrovascular high-risk group

    Hironaka, Masatoshi (Hiroshima Univ. (Japan). School of Medicine)

    1990-04-01

    Magnetic resonance imaging (MRI) study was performed in 32 patients with recent lacunar stroke. T2-weighted images showed ischemic lesions more clearly than T1-weighted images. Sixty-six percent of 32 patients had periventricular lesions. Eighty-four percent had subcortical white matter lesions. Sixty-nine percent had lesions in basal ganglia. Twenty-eight percent had lesions in brainstem. Periventricular lesions were revealed symmetrically. On the other hand, lesions in other areas were not detected symmetrically. Severe periventricular lesions on MRI were similar to those of Binswanger's disease. Patients with severe periventricular lesions had often hypertension. Moreover, two of them had dementia. Twenty-three patients with transient ischemic attack had less remarkable lesions than patients with lacunar stroke. Thirty-seven patients with a history of cerebrovascular risk factors (hypertension, diabetes mellitus) had severer lesions compared with normal controls. Sixty-one percent of controls, who had no cerebrovascular symptoms and signs, had MRI lesions. These results suggest that MRI is useful for detection of cerebral ischemic lesions with no associated clinical symptoms or signs. (author).

    2007-07-01

    In order to enhance their capabilities in clinical risk management (CRM) and to be integrated into safe and effective patient safety organisational processes and systems, neophyte graduate nurses need to be provided with pertinent information on CRM at the beginning of their employment. What and how such information should be given to new graduate nurses, however, remains open to question and curiously something that has not been the subject either of critique or systematic investigation in the nursing literature. This article reports the findings of the third and final cycle of a 12 month action research (AR) project that has sought to redress this oversight by developing, implementing and evaluating a CRM education program for neophyte graduate nurses. Conducted in the cultural context of regional Victoria, Australia, the design, implementation and evaluation of the package revealed that it was a useful resource, served the intended purpose of ensuring that neophyte graduate nurses were provided with pertinent information on CRM upon the commencement and during their graduate nurse year, and enabled graduate nurses to be facilitated to translate that information into their everyday practice.

    The extent of lateral neck dissection (LND) in surgical resection of papillary thyroid carcinoma (PTC) with clinically lateral LNM (LLNM) remains controversial. We aimed to explore the frequency of and risk factors for level V LNM in patients with solitary PTC and clinically LLNM. To analyze the frequency and risk factors for level V LNM, we retrospectively reviewed 220 solitary PTC patients who underwent total thyroidectomy, bilateral central neck dissection, and therapeutic LND. LLNM were present in 82.3% patients, and levels II-V LNM were present in 45.9%, 62.7%, 55.5%, and 12.3% patients, respectively. Ipsilateral level V LNM was significantly associated with tumor size >10 mm, extrathyroidal extension, ipsilateral central LNM ratio ≥50%, and contralateral central LNM (CLNM), bilateral CLNM, and simultaneous levels II-IV LNM. Contralateral CLNM was an independent risk factor for level V LNM. In patients with solitary PTC and clinically LLNM, level V LNM was relatively uncommon. Therefore, routine level V lymphadenectomy may be unnecessary in these patients unless level V LNM is suspected on preoperative examination or associated risk factors, especially contralateral CLNM, are present.

    AIM: To investigate in a prospective study whether a simplified clinical score prior to endoscopy in upper gastrointestinal bleeding (UGIB) patients was able to predict endoscopic findings at urgent endoscopy.METHODS: All consecutive UGIB patients referred to a single endoscopic center during a 16 mo period were enrolled. Before endoscopy patients were stratified according to a simple clinical score (T-score),including T1 (high-risk), T2 (intermediate-risk) and T3 (low-risk). Endoscopy was performed in all cases within 2 h, and high-risk stigmata were considered for further analysis.RESULTS: Out of the 436 patients included into the study, 126 (29%) resulted to be T1, 135 (31%) T2,and 175 (40%) T3. Overall, stigmata of recent haernorrhage (SRH) were detected in 118 cases (27%). SRH occurred more frequently in Tt patients than in T2/T3 cases (85% vs 3.2%; x2 = 304.5309, P < 0.001). Older age (t = 3.311; P <0.01) and presence of comorbidities (x2 = 14.7458; P < 0.01) were more frequently detected in T1 than in T2/T3 patients.CONCLUSION: Our simplified clinical score appeared to be associated with the detection of endoscopic findings which may deserve urgent endoscopy. A further,randomised study is needed to assess its accuracy in safely scheduling endoscopy in UGIB patients.

    2013-01-01

    Since several years risk-based monitoring is the new "magic bullet" for improvement in clinical research. Lots of authors in clinical research ranging from industry and academia to authorities are keen on demonstrating better monitoring-efficiency by reducing monitoring visits, monitoring time on site, monitoring costs and so on, always arguing with the use of risk-based monitoring principles. Mostly forgotten is the fact, that the use of risk-based monitoring is only adequate if all mandatory prerequisites at site and for the monitor and the sponsor are fulfilled.Based on the relevant chapter in ICH GCP (International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use - Good Clinical Practice) this publication takes a holistic approach by identifying and describing the requirements for future monitoring and the use of risk-based monitoring. As the authors are operational managers as well as QA (Quality Assurance) experts, both aspects are represented to come up with efficient and qualitative ways of future monitoring according to ICH GCP.

    Schizotypal personality disorder (SPD) is viewed as a marker of prodromal psychosis. However, information regarding genetic risk (e.g. SPD) is often overlooked in the identification process. This study assessed whether SPD screening questionnaire help the prodromal psychosis (also widely applied "clinical high risk" (CHR) for clinical sample) detection in Chinese mental health service. This work also examined whether SPD had higher frequency in genetic risk population and CHR subjects. Two wave studies concerning the SPD identification was used for analysis. Wave 1 survey: 3075 subjects were assessed by Personality Diagnostic Questionnaire for SPD (PDQ-SPD) and Structured Clinical Interview for DSM-IV Axis II (SCID-II). Wave 2 survey: 2113 subjects screened with the prodromal questionnaire -brief version (PQ-B), PDQ-SPD, and interviewed by Structured Interview for Prodromal Symptoms (SIPS). Subjects with family history of mental disorders or with psychosis reported significantly higher scores in SPD. Receiver operating characteristic curves suggested that PDQ-SPD had moderate sensitivity and specificity for identifying CHR subjects. There was significant higher on SPD features in subjects with early stage (Course less than 1 year) of psychosis. Identifying SPD may be useful in early detection of psychosis especially in detecting the genetic risk syndromes and can be integrated with existing prodromal screen tools to improve its efficiency.

    This study was performed to investigate the clinical characteristics of lupus cystitis and determine the risk factors and clinical outcomes of lupus cystitis in patients with systemic lupus erythematosus (SLE). We retrospectively reviewed 1064 patients at Seoul St. Mary's Hospital in Seoul, Korea, from 1998 to 2013. Twenty-four patients had lupus cystitis. Lupus cystitis was defined as unexplained ureteritis and/or cystitis as detected by imaging studies, cystoscopy, or bladder histopathology without urinary microorganisms or stones. Three-fourths of patients with lupus cystitis had concurrent lupus mesenteric vasculitis (LMV). The initial symptoms were gastrointestinal in nature for most patients (79.2%). High-dose methylprednisolone was initially administered to most patients (91.7%) with lupus cystitis. Two patients (8.3%) died of urinary tract infections. Sixty-five age- and sex-matched patients with SLE who were admitted with other manifestations were included as the control group. Patients with lupus cystitis showed a lower C3 level (p = 0.031), higher SLE Disease Activity Index score (p = 0.006), and higher ESR (p = 0.05) upon admission; more frequently had a history of LMV prior to admission (p lupus (p = 0.031) than did patients with SLE but without lupus cystitis. The occurrence of lupus cystitis was associated with a history of LMV (OR, 21.794; 95% CI, 4.061-116.963). The median follow-up period was 3.4 years, and the cumulative one-year mortality rate was 20%. Complications developed in 33.3% of patients with lupus cystitis and were related to survival (log-rank p = 0.021). Our results suggest that the possibility of lupus cystitis should be considered when a patient with SLE and history of LMV presents with gastrointestinal symptoms or lower urinary tract symptoms. Development of complications in patients with lupus cystitis can be fatal. Thus, intensive treatment and follow-up are needed, especially in the presence of

    2015-06-01

    The effective quality control in clinical practices is an effective guarantee for the authenticity and scientificity of the findings. The post-marketing reevaluation for traditional Chinese medicines (TCM) focuses on the efficacy, adverse reaction, combined medication and effective dose of drugs in the market by expanded clinical trials, and requires a larger sample size and a wider range of patients. Therefore, this increases the difficulty of quality control in clinical practices. With the experience in quality control in clinical practices for the post-marketing reevaluation for Kangbingdu oral for cold, researchers in this study reviewed the study purpose, project, scheme design and clinical practice process from an overall point of view, analyzed the study characteristics of the post-marketing reevaluation for TCMs and the quality control risks, designed the quality control contents with quality impacting factors, defined key review contents and summarized the precautions in clinical practices, with the aim to improve the efficiency of quality control of clinical practices. This study can provide reference to clinical units and quality control-related personnel in the post-marketing reevaluation for TCMs.

  18. Mediators of the Relation Between Community Violence and Sexual Risk Behavior Among Adults Attending a Public Sexually Transmitted Infection Clinic.

    Senn, Theresa E; Walsh, Jennifer L; Carey, Michael P

    2016-07-01

    Prior research shows that violence is associated with sexual risk behavior, but little is known about the relation between community violence (i.e., violence that is witnessed or experienced in one's neighborhood) and sexual risk behavior. To better understand contextual influences on HIV risk behavior, we asked 508 adult patients attending a publicly funded STI clinic in the U.S. (54 % male, M age = 27.93, 68 % African American) who were participating in a larger trial to complete a survey assessing exposure to community violence, sexual risk behavior, and potential mediators of the community violence-sexual risk behavior relation (i.e., mental health, substance use, and experiencing intimate partner violence). A separate sample of participants from the same trial completed measures of sexual behavior norms, which were aggregated to create measures of census tract sexual behavior norms. Data analyses controlling for socioeconomic status revealed that higher levels of community violence were associated with more sexual partners for men and with more episodes of unprotected sex with non-steady partners for women. For both men and women, substance use and mental health mediated the community violence-sexual risk behavior relation; in addition, for men only, experiencing intimate partner violence also mediated this relation. These results confirm that, for individuals living in communities with high levels of violence, sexual risk reduction interventions need to address intimate partner violence, substance use, and mental health to be optimally effective.

    We report a brief discussion on a clinical case of a female patient, 85 years old, affected by severe cognitive impairment and chronic obstructive pulmonary disease (COPD). The patient was not taking drugs at home (apart from promazine: 10 drops when necessary to control her behavioral diseases). A previous neuropsychological evaluation had shown a severe cognitive impairment MMSE=16/30; ADL=3/6; IADL=0/8) due to multiple brain ischemic areas (confirmed in 2003 by MRI neuroimaging). When the patient was admitted to our center she was able to perform some basic activities of daily living such as eating and walking and was not too confused. She was included in cognitive rehabilitation groups. Since she showed signs of Parkinsonism, a therapy based on omeprazol 20mg, acetylsalicylic acid, donepezil 10mg, pramipexol 0.18 mg, nimodipine 10 drops, levodopa+carbidopa 100/25mg was started. A few days later she became sleepy during daytime and, once, she lost her balance and fell. She was not self-sufficient any more. At first this was attributed to a lung infection that the patient had, but her state continue after the infection was completely cured with appropriate antibiotics therapy. At that point an adverse drug reaction was suspected and therapy with pramipexol 0.18 mg was interrupted. In a few days the patient regained her previous level of consciousness and self-sufficiency. We consider this a typical case of complex management in a patient with dementia and comorbidity in which adverse drug reactions can play an important role in lowering the level of cognitive functions. In this case the relationship with the family of the patient was made difficult by the attitude of the patient's daughter who decided, after the onset of the adverse drug reaction, to interrupt her mother's stay in our center even at risk of the worst consequences.

    Purpose: Theoretical dose–response models offer the possibility to assess second cancer induction risks after external beam therapy. The parameters used in these models are determined with limited data from epidemiological studies. Risk estimations are thus associated with considerable uncertainties. This study aims at illustrating uncertainties when predicting the risk for organ-specific second cancers in the primary radiation field illustrated by choosing selected treatment plans for brain cancer patients. Methods: A widely used risk model was considered in this study. The uncertainties of the model parameters were estimated with reported data of second cancer incidences for various organs. Standard error propagation was then subsequently applied to assess the uncertainty in the risk model. Next, second cancer risks of five pediatric patients treated for cancer in the head and neck regions were calculated. For each case, treatment plans for proton and photon therapy were designed to estimate the uncertainties (a) in the lifetime attributable risk (LAR) for a given treatment modality and (b) when comparing risks of two different treatment modalities. Results: Uncertainties in excess of 100% of the risk were found for almost all organs considered. When applied to treatment plans, the calculated LAR values have uncertainties of the same magnitude. A comparison between cancer risks of different treatment modalities, however, does allow statistically significant conclusions. In the studied cases, the patient averaged LAR ratio of proton and photon treatments was 0.35, 0.56, and 0.59 for brain carcinoma, brain sarcoma, and bone sarcoma, respectively. Their corresponding uncertainties were estimated to be potentially below 5%, depending on uncertainties in dosimetry. Conclusions: The uncertainty in the dose–response curve in cancer risk models makes it currently impractical to predict the risk for an individual external beam treatment. On the other hand, the ratio

  2. The communication of the radiation risk from CT in relation to its clinical benefit in the era of personalized medicine: part 2: benefits versus risk of CT.

    In order to personalize the communication of the CT risk, we need to describe the risk in the context of the clinical benefit of CT, which will generally be much higher, provided a CT scan has a well-established clinical indication. However as pediatric radiologists we should be careful not to overstate the benefit of CT, being aware that medico-legal pressures and the realities of health care economics have led to overutilization of the technology. And even though we should not use previously accumulated radiation dose to a child as an argument against conducting a clinically indicated scan (the "sunk-cost" bias), we should consider patients' radiation history in the diagnostic decision process. As a contribution to future public health, it makes more sense to look for non-radiating alternatives to CT in the much larger group of basically healthy children who are receiving occasional scans for widely prevalent conditions such as appendicitis and trauma than to attempt lowering CT use in the smaller group of patients with chronic conditions with a limited life expectancy. When communicating the CT risk with individual patients and their parents, we should acknowledge and address their concerns within the framework of informed decision-making. When appropriate, we may express the individual radiation risk, based on estimates of summated absorbed organ dose, as an order of magnitude rather than as an absolute number, and compare this with the much larger natural cancer incidence over a child's lifetime, and with other risks in medicine and daily life. We should anticipate that many patients cannot make informed decisions on their own in this complex matter, and we should offer our guidance while maintaining respect for patient autonomy. Proper documentation of the informed decision process is important for future reference. In concert with our referring physicians, pediatric radiologists are well-equipped to tackle the complexities associated with the communication

    The objective of this systematic review was to determine if dairy product consumption is detrimental, neutral, or beneficial to cardiovascular health and if the recommendation to consume reduced-fat as opposed to regular-fat dairy is evidence-based. A systematic review of meta-analyses of prospective population studies associating dairy consumption with cardiovascular disease (CVD), coronary artery disease (CAD), stroke, hypertension, metabolic syndrome (MetS), and type 2 diabetes (T2D) was conducted on the basis of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Quality of evidence was rated by using the Grading of Recommendations Assessment, Development, and Evaluation scale. High-quality evidence supports favorable associations between total dairy intake and hypertension risk and between low-fat dairy and yogurt intake and the risk of T2D. Moderate-quality evidence suggests favorable associations between intakes of total dairy, low-fat dairy, cheese, and fermented dairy and the risk of stroke; intakes of low-fat dairy and milk and the risk of hypertension; total dairy and milk consumption and the risk of MetS; and total dairy and cheese and the risk of T2D. High- to moderate-quality evidence supports neutral associations between the consumption of total dairy, cheese, and yogurt and CVD risk; the consumption of any form of dairy, except for fermented, and CAD risk; the consumption of regular- and high-fat dairy, milk, and yogurt and stroke risk; the consumption of regular- and high-fat dairy, cheese, yogurt, and fermented dairy and hypertension risk; and the consumption of regular- and high-fat dairy, milk, and fermented dairy and T2D risk. Data from this systematic review indicate that the consumption of various forms of dairy products shows either favorable or neutral associations with cardiovascular-related clinical outcomes. The review also emphasizes that further research is urgently needed to compare the impact of

    Array comparative genomic hybridization (aCGH) testing can diagnose chromosomal microdeletions and duplications too small to be detected by conventional cytogenetic techniques. We need to consider which patients are more likely to receive a diagnosis from aCGH testing versus patients that have lower likelihood and may benefit from broader genome wide scanning. We retrospectively reviewed charts of a population of 200 patients, 117 boys and 83 girls, who underwent aCGH testing in Genetics Clinic at Rhode Island hospital between 1 January/2008 and 31 December 2010. Data collected included sex, age at initial clinical presentation, aCGH result, history of seizures, autism, dysmorphic features, global developmental delay/intellectual disability, hypotonia and failure to thrive. aCGH analysis revealed abnormal results in 34 (17%) and variants of unknown significance in 24 (12%). Patients with three or more clinical diagnoses had a 25.0% incidence of abnormal aCGH findings, while patients with two or fewer clinical diagnoses had a 12.5% incidence of abnormal aCGH findings. Currently, we provide families with a range of 10-30% of a diagnosis with aCGH testing. With increased clinical complexity, patients have an increased probability of having an abnormal aCGH result. With this, we can provide individualized risk estimates for each patient.

    Obesity disproportionately affects Latina women. Common genetic variants are convincingly associated with body mass index (BMI) and may be used to create genetic risk scores (GRS) for obesity that could define genetically influenced forms of obesity and alter response to clinical trial interventions. The objective of this study was (1) to identify the frequency and effect size of common obesity genetic variants in Latina women; (2) to determine the clinical utility of a GRS for obesity with Latina women participating in a community-based clinical trial. DNA from 85 Latina women was genotyped for eight genetic variants previously associated with BMI in Caucasians, but not yet assessed in Latina populations. The main outcome measure was the correlation of GRS (sum of eight risk alleles) with BMI, waist circumference, and percent body fat. A majority (83%) of participants had a BMI ≥25. Frequency of loci near FTO, MC4R, and GNPDA2 were lower in Latinas than Caucasians. Association of each locus with BMI was lower in Latinas compared to Caucasians with no significant correlations with BMI. We conclude that an eight locus GRS has no clinical utility for explaining obesity or predicting response to intervention in Latina women participating in a clinical trial.

  8. Review of the evidence for the clinical utility of lipoprotein-associated phospholipase A2 as a cardiovascular risk marker.

    Corson, Marshall A; Jones, Peter H; Davidson, Michael H

    2008-06-16

    A substantial body of peer-reviewed studies has been published validating the role of inflammation in atherogenesis and supporting lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) as a cardiovascular risk marker independent of and additive to traditional risk factors. As with elevated high-sensitivity C-reactive protein, an elevated Lp-PLA(2) level approximately doubles the risk for primary and secondary cardiovascular events. Interestingly, when both inflammatory markers are increased together, they provide an even greater predictive capability to help identify very-high-risk individuals who would benefit most from aggressive lipid-lowering therapy. High levels of Lp-PLA(2) are present in inflamed, rupture-prone plaques, and it appears that Lp-PLA(2) is released from these plaques into the circulation. Over 25 prospective epidemiologic studies have demonstrated the association of elevated Lp-PLA(2) levels with future coronary events and stroke-11 of 12 prospective studies have shown a statistically significant association between elevated Lp-PLA(2) and primary coronary or cardiovascular events, 12 of 13 have shown a statistically significant association with recurrent coronary or cardiovascular events, and 6 studies have shown a positive association with stroke. Lp-PLA(2) should be viewed today as an important cardiovascular risk marker whose utility is as an adjunct to the major risk factors to adjust absolute risk status and thereby modify low-density lipoprotein cholesterol goals. The low biologic fluctuation and high vascular specificity of Lp-PLA(2) makes it possible to use a single measurement in clinical decision making, and it also permits clinicians to follow the Lp-PLA(2) marker serially. Ultimately, Lp-PLA(2) may also be classified as a risk factor, but this should not detract from its utility today as a risk marker.

    Three hundred women presenting to a sexually transmitted infection (STI) clinic in Mumbai, India were surveyed and HIV tested. Thirty-nine percent were HIV infected; 80% were current sex workers, and HIV infection was not significantly associated with past-year sex work. Only 44% always used condoms with their noncommercial sex partners. Most believed that condom preparation is a male responsibility (58%); that condom use is a sign that partner trust is lacking (84%); and that if a woman asks her partner to use a condom, he will lose respect for her (65%). All women at STI clinics in India need HIV testing and culturally sensitive risk interventions.

    The development of inhibitors is the most serious iatrogenic complication affecting patients with haemophilia. This complication is associated with impaired vital or functional prognosis, reduced quality of life and increased cost of treatment. The reasons why some patients develop antibodies to factor replacement and others do not remain unclear. It is however clear that inhibitor development results from a complex multifactorial interaction between genetic and non-genetic risk factors. Environmental influences implicated in increasing the risk of inhibitor formation can be viewed as modifiable risk factors. Therefore, identification of the non-genetic risk factors may offer the possibility of personalising haemophilia therapy by modifying treatment strategies in high-risk patients in the critical early phase of factor VIII exposure. In this article, we review the non-genetic factors reported as well as the potential impact of danger signals and the different scores for inhibitor development risk stratification.

    Alcohol-exposed pregnancy (AEP) is a significant public health problem in the United States. Sexually transmitted disease (STD) clinics serve female clients with a high prevalence of heavy alcohol consumption coupled with ineffective contraceptive use. Project CHOICES (Changing High-Risk AlcOhol Use and Increasing Contraception Effectiveness) is an evidence-based, brief intervention to lower risk of AEP by targeting alcohol and contraceptive behaviors through motivational interviewing and individualized feedback. We describe our experience integrating and implementing CHOICES in STD clinics. This endeavor aligns with CDC's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention's program collaboration and service integration strategic priority to strengthen collaborative work across disease areas and integrate services provided by related programs at the client level.

    Background Improved treatment for pediatric cancers has ensured an evergrowing population of patients surviving into adulthood. The current study evaluated the impact of previous engagement in survivor care on patient knowledge and awareness of health risks as young adults. Procedure Young adult survivors of childhood cancers (N = 93, M age = 23.63 y) were recruited during their annual survivor clinic visit. Participants completed self-reported measures of demographics, treatment knowledge, perception of future health risks, participation in previous survivor care, and neurocognitive functioning. Results In total, 82% of patients (N = 76/93) reported previously participating in survivorship care. These patients were more likely to have knowledge of their radiation treatment (P = 0.034) and more likely to recognize risk for future health effects from their treatment (P = 0.019). Income between $10,000 and $24,999 (odds ratio = 0.168; 95% confidence interval, 0.046–0.616; P = 0.031) was associated with decreased patient knowledge regarding diagnosis. Male sex (odds ratio = 0.324; 95% confidence interval, 0.135–0.777; P = 0.012) was associated with less knowledge of future health risks. Patients with self-reported difficulties on the CCSS-NCQ were more likely to regard their cancer treatment as a future health risk. Conclusion Participation in survivor care plays an important role in imparting information to young adult survivors of pediatric cancer regarding their disease history and risk for future health problems.

  15. Peritonsillar abscess: clinical aspects of microbiology, risk factors, and the association with parapharyngeal abscess.

    Klug, Tejs Ehlers

    2017-03-01

    PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated. Complications are relatively rare. They include parapharyngeal abscess (PPA), upper airway obstruction, Lemierre´s syndrome, necrotizing fasciitis, mediastinitis, erosion of the internal carotid artery, brain abscess, and streptococcal toxic shock syndrome. The treatment consists of abscess drainage and antimicrobial therapy. There are three accepted methods of surgical intervension: needle aspiration, incision and drainage (ID), and acute tonsillectomy (á chaud). Internationally, there is a strong trend towards less invasive surgical approach to PTA treatment with avoidance of acute tonsillectomy, needle aspiration instead of ID, and in some cases even antibiotic treatment without surgical drainage. The preferred antibiotic regimen varies greatly between countries and centers. Group A streptococcus (GAS) is the only established pathogen in PTA. However, GAS is only recovered from approximately 20% of PTA patients. The pathogens in the remaining 80% are unknown. Culturing of PTA pus aspirates often yields a polymicrobial mixture of aerobes and anaerobes. As the tonsils of healthy individuals are already heavily and diversely colonized, the identification of significant pathogens is challenging. In addition, when studying PTA microbiology, one must consider diagnostic precision, collection, handling, and

    Jianli Hu

    Full Text Available Scrub typhus, caused by Orientia tsutsugamushi, has emerged recently in Jingjiang City, China where the disease had not been known to exist. We analyzed epidemiological data, clinical characteristics and risk factors of scrub typhus outbreak in Jingjiang City, 2013. The 271 clinically diagnosed patients were predominantly farmers 50 to 69 years old and the peak of onset was early to mid-November. For the 187 laboratory-confirmed cases, the major clinical manifestations of the patients were fever (100%, eschar (88.2%, rash (87.7%, chills (87.7%, and headache (66.8%. A community-based case-control study was carried out to investigate the risk factors of the scrub typhus outbreak. Bundling or moving waste straw (OR=9.0, 95%CI 4.6-17.8 and living at the edge of village (OR=0.6, 95%CI 0.4-0.9 posed the highest risks through single- and multi-variable conditional logistic regression. Phylogenetic analysis of the 56-kDa TSA gene showed that the new cluster (GB-C2 and the previously reported cluster (GB-C1 of O. tsutsugamushi were associated with this outbreak. These findings are useful for the establishment of a detailed control strategy for scrub typhus infection in previously unrecognized areas of Jiangsu Province, China.

  18. Ambulatory ECG-based T-wave alternans monitoring for risk assessment and guiding medical therapy: mechanisms and clinical applications.

    Verrier, Richard L; Ikeda, Takanori

    2013-01-01

    Identification of individuals at risk for sudden cardiac death (SCD), the main cause of adult mortality in developed countries, remains a major challenge. The main contemporary noninvasive marker, left ventricular ejection fraction (LVEF), has not proved adequately reliable, as the majority of individuals who die suddenly have relatively preserved cardiac mechanical function. Monitoring of T-wave alternans (TWA), a beat-to-beat fluctuation in ST-segment or T-wave morphology, on ambulatory electrocardiogram (AECG) is an attractive approach on both scientific and clinical grounds. Specifically, TWA's capacity to assess risk for malignant arrhythmias has been shown to rest on sound electrophysiologic principles and AECG-based TWA monitoring can be performed in the flow of routine clinical evaluation. This review addresses: (1) electrophysiologic and ionic mechanisms underlying TWA's predictivity, (2) principles and practical aspects of AECG-based TWA monitoring, (3) clinical evidence supporting this approach to SCD risk stratification, and (4) current and potential applications in guiding medical therapy.

    BACKGROUND: The 2011 American Heart Association Guidelines on the management of asymptomatic carotid disease recommends that carotid endarterectomy (CEA) (with carotid artery stenting (CAS) as an alternative) may be considered in highly selected patients with 70-99% stenoses. However, no guidance...... was provided as to what "highly selected" meant. This caveat is, however, important as up to 95% of asymptomatic individuals undergoing prophylactic CEA or CAS will ultimately undergo an unnecessary procedure. Even if the procedural risk following CEA or CAS could be reduced to 0%; 93% of patients would still....../CAS. METHODS: Review of clinical and/or imaging based scoring systems, predictive algorithms and imaging parameters that may be associated with an increased (or decreased) risk of stroke in patients with asymptomatic carotid disease.

Our aim was to perform surgical revascularization as soon as the arterial injury was recognized. The mechanism of injury was blunt in the entire cohort of patients, and all of them had bone fractures about the knee. The treatment of arterial injury included vein graft interposition in 39 (63%, primary anastomosis in 20 (32.3%, and lateral repair in 3 (4.8% patients. The patients were divided into 2 study groups: limb salvage group (group 1 and amputation group (group 2. Subgroup analysis consisted of univariate analysis comparing the 2 groups and multivariate analysis examining the factors associated negatively and positively with the primary endpoint, limb salvage.Results: In the entire cohort of patients, 60 patients (97% were male and 2 were female (3%; the mean age was 34.1 years (16–49 years. The overall amputation rate in this study was 37.1% (23 amputations. Significant (P < 0.05 independent factors associated negatively with limb salvage were combined tibia and fibula fracture, concomitant artery and vein injury, ligation of venous injury, and lack of backflow after Fogarty catheter thrombectomy, while repair of popliteal artery and vein injury, when present, was associated with improved early limb salvage. For 40 patients, we adopt a liberal attitude toward open 4-compartment fasciotomy through both medially and laterally placed incisions.Conclusion: Expeditious recognition of vascular

Blebitis was defined as anterior segment inflammation with mucopurulent material in or around the bleb, with anterior chamber cells but no hypopyon. BRE was defined by the presence of hypopyon or vitreous inflammation. Results: Twenty-nine patients with blebitis and 10 with BRE were identified. Mean age of subjects (n=39 was 68.4 (±13.3 with a preponderance of men (74.4% and Chinese ethnicity (74.4%. BRE patients were 10.7 years older than blebitis patients (P=0.026. 28 (71.8% subjects had primary open angle glaucoma. The presenting intraocular pressure (IOP dropped in blebitis but almost doubled in BRE (P=0.011 compared to average preinfective IOP. Two weeks after treatment, IOPs in both groups returned to close to preinfective levels. Subjects with blebitis more often had an avascular bleb (88.0% while those with BRE trended toward a moderately vascular bleb (50%. The distribution of causative microorganisms between the groups was similar. Conclusion: Our study indicates that risk factors are similar in both groups even though the visual outcome and clinical course, in the form of IOP findings and bleb vascularity, can diverge significantly. The decreased IOP in blebitis subjects represents objective evidence of subclinical leaks or bleb sweating. Keywords

    Background:Osteoarthritis often affects the joint bilaterally,and the single-stage (SS) unicompartmental knee arthroplasty (UKA) is advantageous in terms of a single anesthesia administration,a short hospital stay,lower medical costs,and enhanced patient convenience.However,the complication risk of SS UKA continues to be debated.The aim of this article was to evaluate the clinical effectiveness,complications,and functional recovery of SS and two-stage (TS) UKA.Methods:From January 2008 to December 2013,we compared a series of 36 SS UKA with 45 TS UKA for osteoarthritis.The mean age was 65.4 years (range:55-75 years).The mean body mass index was 25.2 kg/m2 (range:22-29 kg/m2).The pre-and post-operative Oxford Knee Scores (OKSs),complications,operative times,tourniquet times,the amount of drainage,and hemoglobin (Hb) were evaluated.The Chi-square test,Fisher's exact test,and paired and grouped t-tests were used in this study.Results:The mean follow-up was 50 months.No complications of death,fat embolism,deep vein thrombosis,and prosthetic infection were reported.Patients who underwent SS UKA had a shorter cumulative anesthesia time (113.5 vs.133.0 min,P < 0.01).There were no significant variations between the values of the mean tourniquet time,the amount of drainage,pre-and post-operative Hb in the different groups.No patient required a blood transfusion.No statistical differences were found in the complications between two groups (P > 0.05).At the final follow-up,the mean OKS improved from 39.48 ± 5.69 to 18.83 ± 3.82 (P < 0.01),with no statistical differences between the two groups (P > 0.05).Patients who underwent SS UKA had a faster recovery.Conclusions:The single-staged UKA offers the benefits of a single anesthesia administration,reduced total anesthetic time,decreased overall rehabilitation time,and absence of an increase in perioperative mortality or complications compared with the TS bilateral UKA.

    Full Text Available Introduction. Death from coronary artery disease (CAD has been until recently considered rare in Nigeria. We present a report of a study of CAD with its predisposing cardiovascular (CVD risk factors in South South Nigeria. Methods. We examined the autopsy reports of 747 coroner cases and 41 consecutive clinically diagnosed cases of ischemic heart disease seen in South South Nigeria. Results. CAD was diagnosed in 13 (1.6% of 747 autopsies. They were predominantly males, urban residents, and of high social class with combination of CVD risk factors of hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activities, and obesity. The mean serum cholesterol of the clinical subjects was 4.7±1.57 mmol/L and 5.07±1.94 mmol/L for angina and myocardial infarction, respectively, which was higher than the mean total cholesterol for locality of 3.1 mmol/L. Conclusion. CAD and its risk factors are contributing to mortality and morbidity in South South Nigeria. These risk factors include hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activity, and obesity. Nigerians in this locality with CAD have raised serum lipids.

    Although it has been recognized for a long time that the predisposition to cardiovascular diseases (CVD) is determined by many risk factors and despite the common use of algorithms incorporating several of these factors to predict the overall risk, there has yet been no global description of the complex way in which CVD risk factors interact with each other. This is the aim of the present study which investigated all existing relationships between the main CVD risk factors in a well-characterized occupational cohort. Prospective associations between 12 behavioural and clinical risk factors (gender, age, parental history of CVD, non-moderate alcohol consumption, smoking, physical inactivity, obesity, hypertension, dyslipidemia, diabetes, sleep disorder, depression) were systematically tested using Cox regression in 10,736 middle-aged individuals free of CVD at baseline and followed over 20 years. In addition to independently predicting CVD risk (HRs from 1.18 to 1.97 in multivariable models), these factors form a vast network of associations where each factor predicts, and/or is predicted by, several other factors (n = 47 with p<0.05, n = 37 with p<0.01, n = 28 with p<0.001, n = 22 with p<0.0001). Both the number of factors associated with a given factor (1 to 9) and the strength of the associations (HRs from 1.10 to 6.12 in multivariable models) are very variable, suggesting that all the factors do not have the same influence within this network. These results show that there is a remarkably extensive network of relationships between the main CVD risk factors which may have not been sufficiently taken into account, notably in preventive strategies aiming to lower CVD risk.

    The incidence of clinical mastitis in dairy cows was estimated in 171 randomly selected dairy herds from the southern part of The Netherlands. A total of 1103 quarter cases was reported. The mean annual incidence rate was 12.7 quarter cases/yr per 100 cows. The modeling incidence rate of clinical mastitis at the herd level indicated that a number of risk factors were associated with a higher rate of clinical mastitis: one or more cows that were leaking milk, one or more cows with trampled teats, no disinfection of the maternity area after calving, consistent use of post-milking teat disinfection, Red and White cattle (Meuse-Rhine-Yssel) as the predominant breed, and an annual bulk milk somatic cell count teats, no disinfection of the maternity area after calving, consistent use of post-milking teat disinfection, use of a thick layer of bedding in the stall, and the stripping of foremilk before cluster attachment. The following risk factors were associated with a higher rate of clinical mastitis caused by Staphylococcus aureus: Red and White cattle (Meuse-Rhine-Yssel) as the predominant breed, cows with trampled teats, the stripping of foremilk before cluster attachment, no regular disinfection of the stall, no regular replacement of stall bedding, and an annual bulk milk somatic cell count < 150,000 cells/ml.

    This systematic review examines critically "best practices" in the training of qualified exercise professionals. Particular attention is given to the core competencies and educational requirements needed for working with clinical populations. Relevant information was obtained by a systematic search of 6 electronic databases, cross-referencing, and through the authors' knowledge of the area. The level and grade of the available evidence was established. A total of 52 articles relating to best practices and (or) core competencies in clinical exercise physiology met our eligibility criteria. Overall, current literature supports the need for qualified exercise professionals to possess advanced certification and education in the exercise sciences, particularly when dealing with "at-risk" populations. Current literature also substantiates the safety and effectiveness of exercise physiologist supervised stress testing and training in clinical populations.

    Background Erectile dysfunction (ED) is especially common in men with major depressive disorder (MDD). This study examined the extent to which risk factors for cardiovascular disease (CVD) and vascular dysfunction were associated with ED severity in a series of MDD patients. Methods The sample included 46 middle-aged [M (SD) age = 53 (7)], sedentary men diagnosed with MDD. ED severity was assessed by the Arizona Sexual Experiences Scale (ASEX), item 3. Depression severity was measured by the Beck Depression Inventory (BDI). CVD risk factors were quantitated by the Framingham Cardiovascular Disease Risk Profile score. Vascular function was measured by flow-mediated dilation (FMD) of the brachial artery. Results The average ASEX score for this sample was 3.2 (SD = 1.2). Regression analysis revealed that ASEX scores were predicted by greater CVD risk factors (p = .008, β = .41) and lower FMD (p = .03, β = −.33). When FMD was included in the regression model, the relationship between CVD risk factors and ASEX scores was partially attenuated (p = .08, β = .28). Conclusions ED was associated with CVD risk and impaired vascular function, although it appears that CVD risk factors may affect ED through impairment of vascular functioning. PMID:19776749

    Non-alcoholic fatty liver disease (NAFLD) is considered to be an independent cardiovascular disease (CVD) risk factor. However, simple steatosis has a benign clinical course without excess mortality. In contrast, the advanced form of NAFLD, non-alcoholic steatohepatitis (NASH) with liver fibrosis increases mortality by approximately 70%, due to an increase in CVD mortality by approximately 300%. Chronic kidney disease (CKD) may be caused by NAFLD/NASH and it substantially increases CVD risk, especially in the presence of type 2 diabetes mellitus. Moreover, CKD may trigger NAFLD/NASH deterioration in a vicious cycle. NAFLD/NASH is also related to increased arterial stiffness (AS), an independent CVD risk factor that further raises CVD risk. Diagnosis of advanced liver fibrosis (mainly by simple non-invasive tests), CKD, and increased AS should be made early in the course of NAFLD and treated appropriately. Lifestyle measures and statin treatment may help resolve NAFLD/NASH and beneficially affect the CVD risk factors mentioned above.

    2015-01-01

    Background:Left ventricular thrombus (LVT) is reported to be a common complication in acute myocardial infarction (AMI) patients.And it has the potential to cause systemic embolism.This retrospective study was to present the current situation of LVT in clinical practice,as well as to evaluate the clinical characteristics and the risk factors of LVT after AMI.Methods:LVT cases (n =96) were identified from 13,732 AMI (non-ST elevation myocardial infarction was excluded) patients in Fuwai Hospital's electronic medical records system from January 2003 to January 2013.The controls (n =192) were gender-and age-matched AMI patients without LVT during this period.A conditional logistic regression (fitted by the Cox model) was performed to identify the independent risk factors.Results:The incidence of LVT after AMI was 0.7%.Univariate analysis indicated that the anterior myocardial infarction (especially extensive anterior myocardial infarction),lower left ventricular ejection fraction (LVEF),LVEF ≤40%,severe regional wall motion abnormalities (RWMA),pericardial effusion,and left ventricular aneurysm were all related to LVT after AMI.The independent risk factors obtained from the conditional logistic regression analysis were lower LVEF (odds ratio (OR) =0.891,95% confidence interval (CI):0.828-0.960),extensive anterior myocardial infarction (OR =6.403,95% CI:1.769-23.169),severe RWMA (OR =7.348,95% CI:1.323-40.819),and left ventricular aneurysm (OR =6.955,95% CI:1.673-28.921).Conclusions:This study indicated that lower LVEF,extensive anterior myocardial infarction,severe RWMA,and left ventricular aneurysm were independent risk factors of LVT after AMI.It also suggested that further efforts are needed for the LVT diagnosis after AMI in clinical practice.

    Saeed, Ayman

    2012-02-01

    AIM: To identify the risk factors for, and to report the microbiological findings and clinical outcomes of, severe microbial keratitis (MK). METHODS: This was a retrospective study of all cases of presumed MK admitted to a tertiary referral center over a 2-year period (September 2001 to August 2003). Data recorded included demographic data, details relating to possible risk factors, results of microbiological studies, clinical findings at presentation, and clinical and visual outcomes. RESULTS: Ninety patients were admitted with a diagnosis of presumed MK during the study period. The mean age of patients was 45 +\\/- 32 years, and the male to female ratio was 47:43 (52.2%:47.7%). Predisposing risk factors for MK included contact lens wear (37; 41.1%), anterior segment disease (19; 21.1%), ocular trauma (13; 14.4%), systemic disease (5; 5.6%), and previous ocular surgery (1; 1.1%). Cultured organisms included gram-negative bacteria (17; 51.5%), gram-positive bacteria (11, 33.3%), acanthamoeba (2; 6.1%), and fungi (1; 3%). Visual acuity improved significantly after treatment [mean best-corrected visual acuity (+\\/-standard deviation) at presentation: 0.76 (+\\/-0.11); mean best-corrected visual acuity at last follow-up: 0.24 (+\\/-0.07); P < 0.001]. Secondary surgical procedures were required in 18 (20%) cases, and these included punctal cautery (1; 1.1%), tissue glue repair of corneal perforation (2; 2.2%), tarsorrhaphy (9; 9.9%), Botulinum toxin-induced ptosis (1; 1.1%), penetrating keratoplasty (3; 3.3%), and evisceration (2; 2.2%). CONCLUSIONS: Contact lens wear remains a significant risk factor for severe MK. MK remains a threat to vision and to the eye, but the majority of cases respond to prompt and appropriate antimicrobial therapy.

    Background It is important to study the factors affecting the clinical mortality of the severe multiple trauma population. The present study was aimed to identify the potential risk factors that could affect mortality rate of acute lung injury (ALI) in severely injured multiple trauma population and to investigate the effects of certain risk factors on the prognosis of different patient subpopulations.Methods This is a follow-up study treating trauma as a single cause for emergency department (ED) and emergency intensive care unit (EICU) admissions. Patients identified with severe multiple trauma with early onset of ALI were enrolled from five trauma centers. Nineteen potential risk factors affecting the prognosis of ALI were examined by univariate and multivariate Logistic regression analyses to identify the ones that affected the mortality of these severe multiple trauma patients.Results There were 687 multiple trauma patients with post-traumatic ALl admitted to ED and EICU during the study period. The six risk factors that affected the mortality with unadjusted odd ratios (ORs) and 95% confidence intervals (Cls)were Acute Physiology Score and Chronic Health Evaluation Score (APACHE) II score, Injury Severity Score (ISS), duration of trauma, age, aspiration of gastric contents, and disseminated intravascular coagulation (DIC). Specific risk factors also affected different patient subpopulations at different degrees (surviving beyond 24 hours, 72 hours, 28 days and with multiple blood transfusions and higher injury scores).Conclusions Factors of APACHE Ⅱ score, ISS and aspiration of gastric contents that could predict the mortality of ALI may exist in the early stage of trauma. Duration of trauma and DIC that greatly affected and predicted the short- and long-term development and mortality of ALI deserve special attention. Elderly patients (aged beyond 65 years) were the independent risk factor for the secondary sepsis and deterioration of pulmonary function

    2010-12-01

    Full Text Available Sydney B Long, Michael J Blaha, Roger S Blumenthal, Erin D MichosJohns Hopkins Ciccarone Center for the Prevention of Heart Disease, Baltimore, MD, USAAbstract: Age is one of the strongest predictors of cardiovascular disease (CVD risk. Treatment with statins can significantly reduce CVD events and mortality in both primary and secondary prevention. Yet despite the high CVD risk among the elderly, there is underutilization of statins in this population (ie, the treatment-risk paradox. Few studies have investigated the use of statins in the elderly, particularly for primary prevention and, as a result, guidelines for treating the elderly are limited. This is likely due to: uncertainties of risk assessment in older individuals where the predictive value of individual risk factors is decreased; the need to balance the benefits of primary prevention with the risks of polypharmacy, health care costs, and adverse medication effects in a population with decreased life expectancy; the complexity of treating patients with many other comorbidities; and increasingly difficult social and economic concerns. As life expectancy increases and the total elderly population grows, these issues become increasingly important. JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin is the largest primary prevention statin trial to date and enrolled a substantial number of elderly adults. Among the 5695 JUPITER participants ≥70 years of age, the absolute CVD risk reduction associated with rosuvastatin was actually greater than for younger participants. The implications of this JUPITER subanalysis and the broader role of statins among older adults is the subject of this review.Keywords: JUPITER, rosuvastatin, elderly, risk

    2009-11-01

    Full Text Available Abstract Background Profound alterations in immune responses associated with uraemia and exacerbated by dialysis increase the risk of developing active tuberculosis (TB in chronic haemodialysis patients (HDPs. In the current study, was determined the impact of various risk factors on TB development. Our aim was to identify which HDPs need anti-TB preventive therapy. Methods Prospective study of 272 HDPs admitted, through a 36-month period, to our institutions. Specific Relative Risk (RR for TB was estimated, considering age matched subjects from the general population as reference group. Entering the study all patients were tested with tuberculin (TST. Using Cox's proportional hazard model the independent effect of various risk factors associated with TB development was estimated. Results History of TB, dialysis efficiency, use of Vitamin D supplements, serum albumin and zinc levels were not proved to influence significantly the risk for TB, in contrast to: advanced age (>65 years, BMI, diabetes mellitus, tuberculin reactivity, healed TB lesions on chest X-ray and time on dialysis. Elderly (>70 years old HDPs (Adjusted RR 25.3, 95%CI 20.4-28.4, P Conclusion The above mentioned factors have to be considered by the clinicians, evaluating for TB in HDPs. Positive TST, the existence of predisposing risk factors and/or old TB lesions on chest X-ray, will guide the diagnosis of latent TB infection and the selection of those HDPs who need preventive chemoprophylaxis.

    The present study was undertaken to determine the bacterial agents present in various clinical solid wastes, general waste and clinical sharp waste. The waste was collected from different wards/units in a healthcare facility in Penang Island, Malaysia. The presence of bacterial agents in clinical and general waste was determined using the conventional bacteria identification methods. Several pathogenic bacteria including opportunistic bacterial agent such as Pseudomonas aeruginosa, Salmonella spp., Klebsiella pneumoniae, Serratia marcescens, Acinetobacter baumannii, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus pyogenes were detected in clinical solid wastes. The presence of specific pathogenic bacterial strains in clinical sharp waste was determined using 16s rDNA analysis. In this study, several nosocomial pathogenic bacteria strains of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Lysinibacillus sphaericus, Serratia marcescens, and Staphylococcus aureus were detected in clinical sharp waste. The present study suggests that waste generated from healthcare facilities should be sterilized at the point of generation in order to eliminate nosocomial infections from the general waste or either of the clinical wastes.

    2015-01-01

    Community-acquired pneumonia (CAP) is one of the most common reasons for physician visits and hospitalizations in North America. Rates of CAP increase with age and CAP is associated with significant morbidity and mortality, especially in the elderly. Though there is much written about the epidemiology and risk factors of incident (first episode) pneumonia, much less is known about recurrent pneumonia. Rates of recurrent pneumonia within 3-5-years of an episode of CAP are 9-12% with a median time to recurrence of 123-317 days and mortality ranging from 4 to 10%. Age ≥65-years-old and impaired functional status are the only patient characteristics that are independently associated with increased risk of recurrence. In terms of modifiable risk factors, only the use of proton-pump inhibitors and systemic and inhaled corticosteroids have consistently been associated with increased risk of recurrent pneumonia, while angiotensin-converting enzyme (ACE) inhibitors may exert a protective effect. Many chronic medical conditions typically associated with increased incident pneumonia-such as chronic obstructive pulmonary disease (COPD), neurological disease (resulting in dysphagia or silent aspiration), and heart failure-were not associated with increased risk of recurrent pneumonia. However, those who are immune-suppressed (e.g., immunoglobulin deficiencies) may be at increased risk of recurrent pneumonia. In summary, among those who survive an episode of pneumonia, recurrence is not uncommon, particularly in the elderly. Following recovery from an episode of pneumonia, patients should be evaluated for risk factors that would predispose to a second episode including seeking evidence of immunosuppression in younger patients and medication optimization, particularly in the elderly.

    Left ventricular thrombosis (LVT) is a major complication of acute myocardial infarction (AMI). In these patients, the benefits of chronic anticoagulation therapy need to be balanced with its pro-hemorrhagic effects. Blood stasis in the cardiac chambers, a risk factor for LVT, is not addressed in current clinical practice. We recently developed a method to quantitatively assess the blood residence time (RT) inside the left ventricle (LV) based on 2D color-Doppler velocimetry (echo-CDV). Using time-resolved blood velocity fields acquired non-invasively, we integrate a modified advection equation to map intraventricular stasis regions. Here, we present how this tool can be used to estimate the risk of LVT in patients with AMI. 73 patients with a first anterior-AMI were studied by echo-CDV and RT analysis within 72h from admission and at a 5-month follow-up. Patients who eventually develop LVT showed early abnormalities of intraventricular RT: the apical region with RT>2s was significantly larger, had a higher RT and a longer wall contact length. Thus, quantitative analysis of intraventricular flow based on echocardiography may provide subclinical markers of LV thrombosis risk to guide clinical decision making.

    Full Text Available Objective: Our aim was to identify the relationship of osteoporosis (OP risk factors with bone mineral density (BMD in patients admitted our outpatient clinic in Trabzon. Materials and Methods: Two hundred one patients with OP or osteopenia were included in this study. Sociodemographic characteristics of the patients were recorded and a standardized interview was employed by the researcher physician. BMD values were measured by dual energy X-ray absorptiometry at lumbar spine and femoral neck. Results: The mean age of the patients was 61.47±10.57 years (182 females/19 males. One hundred fifteen patients (57.2% were osteoporotic and 86 (42.8% were osteopenic. A significant negative correlation was found between age and femoral neck T scores. The number of pregnancies showed a significant negative correlation with lumbar T scores. Body mass index and daily tea consumption showed a negligible positive correlation with femoral neck T scores. No association was found between age at menarche, age at menopause, total lactation duration, daily calcium intake and T scores of lumbar spine and femoral neck. Conclusions: Identification of regional OP risk factors may be useful for the OP risk management of patients in clinical practice.

    Objective. To report two year clinical outcomes of image guided radiation therapy (IGRT) to the vaginal cuff and pelvic lymph nodes in a series of high-risk endometrial cancer patients. Methods . Twenty-six consecutive high-risk endometrial cancer patients requiring adjuvant radiation to the vaginal cuff and regional lymph nodes were treated with vaginal cuff fiducial-based IGRT. Seventeen (65%) received sequential chemotherapy, most commonly with a sandwich technique. Brachytherapy followed external radiation in 11 patients to a median dose of 18 Gy in 3 fractions. The median external beam dose delivered was 47.5 Gy in 25 fractions. Results. All 656 fractions were successfully imaged and treated. The median overall translational shift required for correction was 9.1 mm (standard deviation, 5.2 mm) relative to clinical set-up with skin tattoos. Shifts of 1 cm, 1.5 cm, and 2 cm or greater were performed in 43%, 14%, and 4% of patients, respectively. Acute grade 2 gastrointestinal (GI) toxicity occurred in eight patients (30%) and grade 3 toxicity occurred in one. At two years, there have been no local or regional failures and actuarial overall survival is 95%. Conclusion. Daily image guidance for high-risk endometrial cancer results in a low incidence of acute GI/genitourinary (GU) toxicity with uncompromised tumor control at two years. Vaginal cuff translations can be substantial and may possibly result in underdosing if not properly considered.

  7. Progestagen component in combined hormone replacement therapy in postmenopausal women and breast cancer risk: a debated clinical issue.

    2009-12-01

    The relevance of the progestagen component in combined hormone replacement therapy (HRT) for breast cancer risk has been long debated. In vitro studies have shown that progestins exert both genomic transcriptional and non-genomic effects that can enhance the proliferation, invasiveness and spread of breast cancer cells. According to a novel hypothesis, progestins can still activate cancer stem cells in patients with pre-existing, clinically undetected breast cancer. However, some experimental and clinical data suggest that different progestins may have a different impact on the pathophysiology of malignant breast cells. In vitro studies on estrogen receptor (ER)+ breast cancer cells have shown that the addition of medroxyprogesterone acetate (MPA) to estradiol (E(2)) produces a significantly higher increase of the mRNA levels and activities of estrogen-activating enzymes aromatase, 17beta hydroxysteroid dehydrogenase type-1 and sulfatase when compared with progesterone plus E(2). In randomised trial performed on ovariectomised adult female monkeys, oral E(2) plus MPA have resulted in a significantly greater proliferation of breast lobular and ductal epithelium when compared with placebo, whereas E(2) plus micronised progesterone have not. In the same experimental model, oral E(2) plus MPA have been found to induce the expression of genes encoding epidermal growth factor receptor (EGFR) ligands and downstream targets, whereas E(2) alone or E(2) plus micronised progesterone had no or modest effects on EGFR-related genes. In last years, some clinical studies on HRT users have shown that androgenic progestin- or MPA-based formulations are associated with an increased breast cancer incidence, whereas micronised progesterone- or dydrogesterone-based formulations are not. Further basic and clinical investigations on this topic are strongly warranted to elucidate whether the choice of the progestagen component in combined HRT could be of clinical relevance as for breast

    Background Understanding risks is considered to be crucial for informed decision-making. Inaccurate risk perception is a common finding in women with a family history of breast cancer attending genetic counseling. As yet, it is unclear how risks should best be communicated in clinical practice. This study protocol describes the design and methods of the BRISC (Breast cancer RISk Communication) study evaluating the effect of different formats of risk communication on the counsellee's risk perception, psychological well-being and decision-making regarding preventive options for breast cancer. Methods and design The BRISC study is designed as a pre-post-test controlled group intervention trial with repeated measurements using questionnaires. The intervention-an additional risk consultation-consists of one of 5 conditions that differ in the way counsellee's breast cancer risk is communicated: 1) lifetime risk in numerical format (natural frequencies, i.e. X out of 100), 2) lifetime risk in both numerical format and graphical format (population figures), 3) lifetime risk and age-related risk in numerical format, 4) lifetime risk and age-related risk in both numerical format and graphical format, and 5) lifetime risk in percentages. Condition 6 is the control condition in which no intervention is given (usual care). Participants are unaffected women with a family history of breast cancer attending one of three participating clinical genetic centres in the Netherlands. Discussion The BRISC study allows for an evaluation of the effects of different formats of communicating breast cancer risks to counsellees. The results can be used to optimize risk communication in order to improve informed decision-making among women with a family history of breast cancer. They may also be useful for risk communication in other health-related services. Trial registration Current Controlled Trials ISRCTN14566836. PMID:18834503

    2012-08-01

    Full Text Available The objective of this study was to compare the perceptions of two families living in two different neighborhoods (rated according to risk levels regarding social support. A questionnaire was designed to assess social support according to the following dimensions: instrumental, emotional, religious, and support from friends, neighbors and family. The sample was comprised as follows: considering the 114 families living in neighborhood 1, 52 families were interviewed; and among the 162 families living in neighborhood 2, 60 families were interviewed. No significant difference was found related to instrumental, religious and emotional support, including the support from relatives among the families from both neighborhoods. The results disagree with the reviewed literature, which indicated a strong association between social support and families living at socioeconomic risk. In conclusion, social support is important for families, regardless of their risk stratification.

    2000-01-01

    In 56 patients aged from 58 to 82 years with the III and IV degrees of risk operated upon for malignant tumors of organs of the thoracic and abdominal organs Solcoseryl was included in the complex of anesthesia measures. It was given intravenously or as inhalation in dosage of 1000 mg. It was found that using Solcoseryl considerably reduced the amount of postoperative complications in high risk patients. It led to lower level of lipid peroxidation and activation of the antioxidant system and thus may be considered as an important component of therapy at the intra- and postoperative periods.

    Wanda Scherrer de Araújo

    Full Text Available ABSTRACT Objective: to analyse the effects of relaxation as a nursing intervention on the depression levels of hospitalised women with high-risk pregnancies. Methods: a randomised clinical trial realised in a reference centre for high-risk pregnancies. The sample consisted of 50 women with high-risk pregnancies (25 in the control group and 25 in the intervention group. The Benson relaxation technique was applied to the intervention group for five days. Control variables were collected using a predesigned form, and the signs and symptoms of depression were evaluated using the Edinburgh Postnatal Depression Scale (EPDS. The Statistical Package for Social Sciences (SPSS, version 20.0, was used with a significance level of 5%. The Wilcoxon and paired t-tests were used to evaluate depression levels between two timepoints. Using categorical data, the McNemar test was used to analyse differences in depression severity before and after the intervention. Results: depression levels decreased in the intervention group five days after the relaxation technique was applied (4.5 ± 3, p<0.05 compared with the levels at the first timepoint (10.3±5.9. Conclusion: as a nursing intervention, relaxation was effective in decreasing the symptoms of depression in hospitalised women with high-risk pregnancies.

    2014-10-01

    Full Text Available Objective: Vulvovaginitis candidiasis and trichomoniasis constitute at least 50% of infectious vaginitis cases. The aim of this study was to determine the prevalence, risk factors, and clinical findings of candidiasis and trichomoniasis in women supported by selected health centers of Tabriz, Iran. Materials and Methods: This was a cross-sectional study, in which 1000 women who had the study criteria were selected by random sampling. In addition, 12 health centers of Tabriz were selected for this study. A questionnaire was used to obtain their personal and reproductive information, checklist for clinical observations, and culture methods (sabouraud dextrose agar and diamond for diagnose vaginal infections. Results: The prevalence of candidiasis and trichomoniasis were 25.2 and 9.2%, respectively. Findings showed that candidiasis infection, history of diseases, vaginal pH, number of coitus, number of delivery, and number of vaginal delivery, breast feeding status, method of last delivery, and contraceptive methods are risk factors for candidacies. Moreover, age at marriage, personal health, sexual hygiene, and vaginal pH are risk factors for trichomoniasis. A statistically significant relationship was observed between candidiasis and clinical findings, such as pruritus, pruritus during coitus, burning sensation with coitus, dysuria in woman and her husband, dyspareunia, low abdominal pain, urinal symptoms, vaginal status, amount of discharge, consistency appearance, and color of discharges. Furthermore, a significant relationship was observed between trichomoniasis and dysuria, and appearance and color of vaginal discharge. Conclusion: Due to the high prevalence of candidiasis, trichomoniasis infections, and infected women as asymptomatic carriers, it seems necessary to pay more attention to these infections and make efforts for their prevention.

  19. Frequency of Metabolic Risk Factors in Children with Urinary Tract Stones Referred to Hamadan Pediatric Nephrology Clinic

    H.E. Momtaz

    2012-07-01

    Full Text Available Introduction & Objective: Urinary stones are among the most common complaints referred to nephrologist and urologists. Although incidence of urolithiasis is low in children compared to adults and only 7% of all urinary stones are diagnosed before the age of 16 but stones are detected more frequently in pediatric age group in recent years. Metabolic derangements, infection, neurogenic bladder and urinary obstruction are major risk factors of urolithiasis. Common metabolic risk factors of urolithiasis in children are hypercalciuria, uricosuria, hypocitraturia, hyperoxaluria, metabolic acidosis and cystinuria. There are many clinical studies about the frequency of these metabolic risk factors with different results reflecting difference in diet, geographic area and genetics in study populations. In this study we tried to evaluate the frequency of metabolic causes of urinary stones in children referred to Hamadan pediatric nephrology clinic.Materials & Methods: In this cross sectional-descriptive study 156 patients referred due to urinary stones to pediatric nephrology clinic underwent thorough metabolic evaluations including: serum calcium,phosphorus, uric acid, creatinine and non fasting random urine sample for calcium, creatinine , uric acid , oxalate, citrate and cystine . urine solute: creatinine ratios were calculated and compared with normative data.Results: Of 156 patients 136(87.2% had metabolic derangements including: hyperuricosuria in 71 (45.5%, hypercalciuria in 41(26.3%, hypocitraturia in 26 (16.7%, hyperoxaluria in 16(10.3%,cystinuria in 1(0.6% and metabolic acidosis in 39 (25%.Conclusion: High rate of metabolic derangement in pediatric urinary stone patients mandates proper metabolic evaluation in all of them. hyperuricosuria was the most common metbolic finding instead of hypercalciuria in this study. This could be due to differences in diet, geographic area and genetic background in various populations.(Sci J Hamadan Univ Med Sci

  20. Loss of PTEN expression is associated with increased risk of recurrence after prostatectomy for clinically localized prostate cancer.

    Chaux, Alcides; Peskoe, Sarah B; Gonzalez-Roibon, Nilda; Schultz, Luciana; Albadine, Roula; Hicks, Jessica; De Marzo, Angelo M; Platz, Elizabeth A; Netto, George J

    2012-11-01

    PTEN (phosphatase and tensin homolog on chromosome 10) is one of the most frequently lost tumor suppressor genes in human cancers and it has been described in more than two-thirds of patients with advanced/aggressive prostate cancer. Previous studies suggest that, in prostate cancer, genomic PTEN loss is associated with tumor progression and poor prognosis. Thus, we evaluated whether immunohistochemical PTEN expression in prostate cancer glands was associated with higher risk of recurrence, using a nested case-control study that included 451 men who recurred and 451 men who did not recur with clinically localized prostate cancer treated by radical prostatectomy. Recurrence was defined as biochemical recurrence (serum prostate-specific antigen >0.2 ng/ml) or clinical recurrence (local recurrence, systemic metastases, or prostate cancer-related death). Cases and controls were matched on pathological T stage, Gleason score, race/ethnicity, and age at surgery. Odds ratios of recurrence and 95% confidence intervals were estimated using conditional logistic regression to account for the matching factors and to adjust for year of surgery, preoperative prostate-specific antigen concentrations, and status of surgical margins. Men who recurred had a higher proportion of PTEN negative expression (16 vs 11%, P=0.05) and PTEN loss (40 vs 31%, P=0.02) than controls. Men with markedly decreased PTEN staining had a higher risk of recurrence (odds ratio=1.67; 95% confidence intervals 1.09, 2.57; P=0.02) when compared with all other men. In summary, in patients with clinically localized prostate cancer treated by prostatectomy, decreased PTEN expression was associated with an increased risk of recurrence, independent of known clinicopathological factors.

  2. Prevalence and predictors of Lymphogranuloma venereum in a high risk population attending a STD outpatients clinic in Italy

    2014-01-01

    Background We evaluated LGV prevalence and predictors in a high risk population attending a STI Outpatients Clinic in the North of Italy. Methods A total of 108 patients (99 MSM and 9 women), with a history of unsafe anal sexual intercourses, were enrolled. Anorectal swabs and urine samples were tested for Chlamydia trachomatis (CT) DNA detection by Versant CT/GC DNA 1.0 Assay (Siemens Healthcare Diagnostics Terrytown, USA). RFLP analysis was used for CT molecular typing. Results L2 CT genotype was identified in 13/108 (12%) rectal swabs. All LGV cases were from MSM, declaring high-risk sexual behaviour and complaining anorectal symptoms. Patients first attending the STI Outpatient Clinic received a significant earlier LGV diagnosis than those first seeking care from general practitioners or gastroenterologists (P = 0.0046). LGV prevalence and characteristics found in our population are in agreement with international reports. Statistical analysis showed that LGV positive patients were older (P = 0.0008) and presented more STIs (P = 0.0023) than LGV negative ones, in particular due to syphilis (P < 0.001), HIV (P < 0.001) and HBV (P = 0.001). Multivariate logistic regression analysis revealed that HIV and syphilis infections are strong risk factors for LGV presence (respectively, P = 0.001 and P = 0.010). Conclusions Even if our results do not provide sufficient evidence to recommend routine screening of anorectal swabs in high-risk population, they strongly suggest to perform CT NAAT tests and genotyping on rectal specimens in presence of ulcerative proctitis in HIV and/or syphilis-positive MSM. In this context, CT DNA detection by Versant CT/GC DNA 1.0 Assay, followed by RFLP analysis for molecular typing demonstrated to be an excellent diagnostic algorithm for LGV identification.

    Full Text Available Patients undergoing noncardiac surgery are at risk of adverse perioperative and long-term outcome. When considering a patient for noncardiac surgery, a careful preoperative clinical risk evaluation and subsequent risk-reduction strategies are essential to reduce postoperative complications. To assist physicians with decision making, clinical guidelines are developed. The aim of clinical guidelines is to improve patient care by providing recommendations about appropriate healthcare in specific circumstances. Development of clinical guidelines is an important component in improving the quality of care. By translating the best available scientific evidence into specific recommendations, guidelines can serve as a useful tool to achieve effective and efficient patient care. In 2009, the first European Society of Cardiology guidelines on perioperative care were developed. This decisionmaking process integrates clinical markers, early coronary evaluation, functional capacity, and the type of surgery involved.

    Full Text Available Hypertensive disorders in pregnancy remain important problem of modern obstetrics, their frequency being 2-8% with no tendency of decreasing. To identify pregnant women with high risk and to conduct preventive treatment is very important for the practitioner. The aim of the study was to develop and justify differential management of pregnants depending on the risk of preeclampsia. 131 pregnant women in I trimester were tested to determine the risk of hypertensive disorders. Prediction model allows to identify pregnant women with risk of hypertensive disorders according to the results of testing thrombophilia genes (presence of 455G → A polymorphism in the gene for fibrinogen β and 4G/5G in gene of plasminogen activator inhibitor - type 1, the level of antibodies to β2 glycoprotein-1, the level of D-dimer and the value of atherogenicity coefficient. Pregnant women with high risk of hypertensive disorders, received prophylactic treatment complex. This complex included antiplatelet therapy, correction of hyperho¬mo¬cysteinemia and hypercholesterolemia levels. Etio-pathogenic concept of prediction and prevention of pre-eclampsia associated with thrombophilia was proposed. The proposed scheme of preventive treatment allowed to normalize blood clotting parameters, lipid metabolism, to reduce the number of thrombophilia markers. The necessity of early and long-term administration of prophylactic complex was proved. This management prevents endothelial damage and deve¬lopment of pathological range of pre-eclampsia. The results of prophylactic treatment were the reduction of preeclampsia cases by 6,5 times (p < 0.05, number of complicated deliveries by 3 times (p <0.05, number of preterm birth by 6,57 times (p <0.05, cases of growth retardation by 9,8 times (p = 0.003, increase of newborns’ weight by 1,24 times (p = 0.02.

  17. Women at high risk of breast cancer: Molecular characteristics, clinical presentation and management.

    Kleibl, Zdenek; Kristensen, Vessela N

    2016-08-01

    The presence of breast cancer in any first-degree female relative in general nearly doubles the risk for a proband and the risk gradually increases with the number of affected relatives. Current advances in molecular oncology and oncogenetics may enable the identification of high-risk individuals with breast-cancer predisposition. The best-known forms of hereditary breast cancer (HBC) are caused by mutations in the high-penetrance genes BRCA1 and BRCA2. Other genes, including PTEN, TP53, STK11/LKB1, CDH1, PALB2, CHEK2, ATM, MRE11, RAD50, NBS1, BRIP1, FANCA, FANCC, FANCM, RAD51, RAD51B, RAD51C, RAD51D, and XRCC2 have been described as high- or moderate-penetrance breast cancer-susceptibility genes. The majority of breast cancer-susceptibility genes code for tumor suppressor proteins that are involved in critical processes of DNA repair pathways. This is of particular importance for those women who, due to their increased risk of breast cancer, may be subjected to more frequent screening but due to their repair deficiency might be at the risk of developing radiation-induced malignancies. It has been proven that cancers arising from the most frequent BRCA1 gene mutation carriers differ significantly from the sporadic disease of age-matched controls in their histopathological appearances and molecular characteristics. The increased depth of mutation detection brought by next-generation sequencing and a better understanding of the mechanisms through which these mutations cause the disease will bring novel insights in terms of oncological prevention, diagnostics, and therapeutic options for HBC patients.

    2012-02-01

    Full Text Available Abstract Background Data on clinical characteristics and outcomes in regard to hip fracture (HF type are controversial. This study aimed to evaluate whether clinical and laboratory predictors of poorer outcomes differ by HF type. Methods Prospective evaluation of 761 consecutively admitted patients (mean age 82.3 ± 8.8 years; 74.9% women with low-trauma non-pathological HF. Clinical characteristics and short-term outcomes were recorded. Haematological, renal, liver and thyroid status, C-reactive protein, cardiac troponin I, serum 25(OH vitamin D, PTH, leptin, adiponectin and resistin were determined. Results The cervical compared to the tronchanteric HF group was younger, have higher mean haemoglobin, albumin, adiponectin and resistin and lower PTH levels (all P 20 days CAD, and age > 75 years and hyperparathyroidism, respectively. Need of institutionalisation was predicted by age > 75 years and dementia in both groups and also by hypovitaminosis D in the cervical and by hyperparathyroidism in the trochanteric HF. Conclusions Clinical characteristics and incidence of poorer short-term outcomes in the two main HF types are rather similar but risk factors for certain outcomes are site-specific reflecting differences in underlying mechanisms.

    Background Atherosclerosis as a cardiovascular disease was found to begin even in the fetal period. However,information about risk factors of pre-clinical atherosclerosis in childhood has been limited. Hence, this study was aimed to find out the risk factors of atherosclerosis by measuring the carotid artery intima-media thickness in children. High resolution B-mode ultrasound used to examine the carotid artery intima-media thickness was demonstrated to be useful in finding the early carotid structural changes.Methods The study included 79 children who were divided into two groups according to their ages: group Ⅰ consisted of 42 children with ages from 5 to 9 years and group Ⅱ consisted of 37 children with ages from 10 to 18 years, Among them,23 had a positive family history for risk, such as hypertension, obesity or dyslipidemia. Blood samples were collected and total cholesterol, triglycerides, high density lipoprotein and low density lipoprotein were assayed. The carotid artery intima-media thickness was measured by ultrasound. Comparisons were done between the two groups using Student's t tests and Chi-square analysis. Body mass index, blood pressure, levels of lipids, family history and the carotid artery intima-media thickness were calculated by conditional logistic regression analysis.Results Compared with the children without a positive family history, the incidence of the increased carotid artery intima-media thickness was significantly high (x2=4.364, P<0.05). There were no statistically significant differences between left and right carotid arteries in carotid artery intima-media thickness (P>0.05). In this study, diastolic blood pressure and the atherosclerosis index were suggested to be the risk factors to the thickened carotid artery intima-media thickness. In group I the diastolic blood pressure's odds radio was 1.187 (P=0.035) and the atherosclerosis index odds radio was 37.165 (P=0.001); in group Ⅱ the diastolic blood pressure's odds

  20. Feasibility and Clinical Outcomes of Peripheral Drug-Coated Balloon in High-Risk Patients with Femoropopliteal Disease.

    Shih-Jung Jang

    Full Text Available Clinical outcomes of the drug-coated balloon (DCB procedure in high-risk patients with femoropopliteal (FP disease have not been investigated sufficiently.This retrospective, single-center study analyzed 87 patients (39% dialysis and 97 affected legs (64% critical limb ischemia [CLI] that underwent DCB for symptomatic FP disease from March 2013 to September 2014. Risk stratification was based on FeDCLIP (female, diabetes, dialysis, CLI, lesion length >150 mm and poor runoff score. The DCB outcomes among the different risk groups were compared and factors predicting restenosis were analyzed during follow-up.Most of study participants (84% were moderate to high-risk patients. The procedural success rate was 100% and the 30-day major adverse vascular event rate was 2.1%. The mean lesion length was 178 ± 106 mm and the mean follow-up time was 428 ± 145 (range 50-782 days. The binary restenosis-free and clinically driven target lesion revascularization (CD-TLR-free rates at 12 months were 77.5% and 84.3%, respectively, for all participants. No significant differences were observed in 1-year binary restenosis and CD-TLR rates in the low-, moderate-, and high-risk groups (60%, 84%, and 73%: p = 0.396; 78%, 89%, and 80%: p = 0.635, respectively. In multivariate analysis, lesion length >150 mm (Hazard ratio [HR]: 8.00, 95% confidence interval (CI 1.12 to 55.6, p = 0.038 and Rutherford class 6 (HR: 7.09, 95% CI, 1.15 to 43.5, p = 0.034 were identified as independent predictors of binary restenosis.Despite general comorbidities and advanced limb ischemia, 1-year outcomes of DCB in high-risk patients with FP disease were effective. The DCB procedure holds promise to improve vessel patency; however, lesion length >150 mm and major tissue loss were independent predictors for binary restenosis after the treatment.

  1. Development and validation of a clinical scoring system for predicting risk of HCC in asymptomatic individuals seropositive for anti-HCV antibodies.

    Mei-Hsuan Lee

    Full Text Available BACKGROUND: The development of a risk assessment tool for long-term hepatocellular carcinoma risk would be helpful in identifying high-risk patients and providing information of clinical consultation. METHODS: The model derivation and validation cohorts consisted of 975 and 572 anti-HCV seropositives, respectively. The model included age, alanine aminotransferase (ALT, the ratio of aspirate aminotransferase to ALT, serum HCV RNA levels and cirrhosis status and HCV genotype. Two risk prediction models were developed: one was for all-anti-HCV seropositives, and the other was for anti-HCV seropositives with detectable HCV RNA. The Cox's proportional hazards models were utilized to estimate regression coefficients of HCC risk predictors to derive risk scores. The cumulative HCC risks in the validation cohort were estimated by Kaplan-Meier methods. The area under receiver operating curve (AUROC was used to evaluate the performance of the risk models. RESULTS: All predictors were significantly associated with HCC. The summary risk scores of two models derived from the derivation cohort had predictability of HCC risk in the validation cohort. The summary risk score of the two risk prediction models clearly divided the validation cohort into three groups (p<0.001. The AUROC for predicting 5-year HCC risk in the validation cohort was satisfactory for the two models, with 0.73 and 0.70, respectively. CONCLUSION: Scoring systems for predicting HCC risk of HCV-infected patients had good validity and discrimination capability, which may triage patients for alternative management strategies.

    Full Text Available Background. Osteoporosis is a debilitating condition characterized by fractures, pain and premature death. Risk factors for osteoporosis predict the risk of fragility fractures. Aim. To describe the occurrence of risk factors for osteoporosis among populations in Nuuk, the capital of Greenland. Methods. A random sample of women born in 1934–42, 1945–47, 1956, and men born in 1956 were selected from the national civil registry. A questionnaire was sent out in Greenlandic and Danish on risk factors for osteoporosis: family history, smoking habits, alcohol intake, presence of disease, sun exposure, intake of dairy products, age at menopause (women and number of falls. Additional questions included the frequency of back pain, previous fractures, intake of vitamin D and calcium supplements, use of anti-osteoporotic drugs, steroids and other drugs. Results. The questionnaire was sent to 317 subjects confirmed to be living at an address in Nuuk and 181 (57.1% responded. More young women than older women were smokers (60.6% vs. 35.0%; p=0.022 while limited sun exposure was reported by more of the old women (37.2% vs. 5.6%; p=0.003. Family history of osteoporosis was reported by 15.0%, without difference between groups. Alcohol and milk intake did not differ between groups. Premature menopause was reported by 17.9% of the women. Falls within the last year were reported by 42.4% with fewer falls in the oldest age group (21.9% vs. 50.0%; p=0.005. Frequency of fragility fractures increased with age (5.7% vs. 24.3% vs. 30.4%; p=0.02 and the risk of a fragility fracture increased with age (p=0.004; OR, 95% CI: 4.5, 1.6–12.2, reference: below 70 years, when adjusted for smoking, gender and falls. The use of anti-osteoporotic drugs was low (3.4% while 28.8% took calcium and vitamin D supplements. Conclusions. Age is a dominating risk factor for fragility fractures in Greenland. The use of anti-osteoporotic drugs is low in Greenland, even if osteoporotic

  5. Risk factors for colorectal cancer in patients with multiple serrated polyps: a cross-sectional case series from genetics clinics.

    Daniel D Buchanan

    Full Text Available Patients with multiple serrated polyps are at an increased risk for developing colorectal cancer (CRC. Recent reports have linked cigarette smoking with the subset of CRC that develops from serrated polyps. The aim of this work therefore was to investigate the association between smoking and the risk of CRC in high-risk genetics clinic patients presenting with multiple serrated polyps.We identified 151 Caucasian individuals with multiple serrated polyps including at least 5 outside the rectum, and classified patients into non-smokers, current or former smokers at the time of initial diagnosis of polyposis. Cases were individuals with multiple serrated polyps who presented with CRC. Controls were individuals with multiple serrated polyps and no CRC. Multivariate logistic regression was performed to estimate associations between smoking and CRC with adjustment for age at first presentation, sex and co-existing traditional adenomas, a feature that has been consistently linked with CRC risk in patients with multiple serrated polyps. CRC was present in 56 (37% individuals at presentation. Patients with at least one adenoma were 4 times more likely to present with CRC compared with patients without adenomas (OR = 4.09; 95%CI 1.27 to 13.14; P = 0.02. For females, the odds of CRC decreased by 90% in current smokers as compared to never smokers (OR = 0.10; 95%CI 0.02 to 0.47; P = 0.004 after adjusting for age and adenomas. For males, there was no relationship between current smoking and CRC. There was no statistical evidence of an association between former smoking and CRC for both sexes.A decreased odds for CRC was identified in females with multiple serrated polyps who currently smoke, independent of age and the presence of a traditional adenoma. Investigations into the biological basis for these observations could lead to non-smoking-related therapies being developed to decrease the risk of CRC and colectomy in these patients.

    With estimates of dementia expected to rise over the coming decades, there is interest in understanding the factors associated with promoting neuroprotection and limiting neurodegeneration. In this study, we examined the change in the volume of the hippocampus over a 2-month period in 34 older people "at risk" of cognitive decline (mean age = 66.8 years, 38% male). Factors that were examined included cognitive reserve, neuropsychological functioning, depression as well as a lifestyle (cognitive training) intervention. The results showed that over a 2-month period, increases in hippocampal size were associated with having higher premorbid intellect, greater occupational attainment, superior memory, and higher levels of functioning. Conversely, depression and disability were associated with decreases in hippocampal volume. Cognitive training was not associated with changes in hippocampal volume. These findings suggest that factors associated with cognitive reserve, cognition and depression may play an integral pathophysiological role in determining hippocampal volumes in "at-risk" older adults.

    2014-07-01

    Full Text Available Stephanie A Cohen,1 Anna Leininger2 1Cancer Genetics Risk Assessment Program, St Vincent Health, Indianapolis, IN, USA; 2Minnesota Oncology, Woodbury, MN, USA Abstract: Lynch syndrome is the most common cause of hereditary colon cancer, and accounts for as much as 3% of all colon and endometrial cancers. The identification and management of individuals with Lynch syndrome have evolved over the past 20 years, yet the syndrome remains vastly underdiagnosed. It is important for clinicians to recognize individuals and families who are at risk in order to be able to manage them appropriately and reduce their morbidity and mortality from this condition. This review will touch on the history of Lynch syndrome, the current knowledge of genotype–phenotype correlations, the cancers associated with Lynch syndrome, and management of individuals who are gene carriers.

    Using a methodological perspective grounded in science and technology studies, this article analyzes two sociotechnical devices used in Argentine reproductive medicine (biostatistical measures and donation registries) with the aim of controlling both the so-called “genetic risk” arising from the use of donated ova as well as the health risks to female donors. By examining how the deployment of monitoring criteria disregards the specificity of ova donation, the article suggests that it is not ...

  13. Warfarin pharmacology, clinical management, and evaluation of hemorrhagic risk for the elderly.

    Jacobs, Laurie G

    2006-02-01

    Elderly patients as a group may present more of a challenge in managing warfarin therapy because of alterations in pharmacokinetics from other medications, diet, and disease; pharmacodynamic changes; increased risk for hemorrhage; and difficulty in monitoring. The elderly, however, may derive the most benefit from warfarin therapy for certain indications, such as the prevention of stroke in atrial fibrillation or recurrent events following deep venous thrombosis. Warfarin can be managed as effectively as in other populations with careful attention to these issues.

    AIM: To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS: Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes(15.4%). None of the preoperative morphologic features were affected the rate of the recurrence. However, an age <40y [P =0.085, odds ratio(OR) 3.609, 95% confidence interval(CI) 0.838-15.540]and amniotic membrane graft instead of conjunctival autograft(P =0.002, OR 9.093, 95% CI 2.316-35.698) were statistically significant risk factors for recurrence.Multivariate analysis revealed that intraoperative mitomycin C(MMC)(P =0.072, OR 0.298, 95% CI 0.080-1.115)decreased the rate of recurrence. CONCLUSION: Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation(AMT) are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence.

  16. The schizophrenia risk gene ZNF804A: clinical associations, biological mechanisms and neuronal functions.

    Chang, H; Xiao, X; Li, M

    2017-03-14

    ZNF804A (zinc-finger protein 804A) has been recognized as a schizophrenia risk gene across multiple world populations. Its intronic single-nucleotide polymorphism (SNP) rs1344706 is among one of the strongest susceptibility variants that have achieved genome-wide significance in genome-wide association studies (GWAS) for schizophrenia and has been widely and intensively studied. To elucidate the biological mechanisms underlying the genetic risk conferred by rs1344706, we retrospectively analyzed the progresses in brain gene expression quantitative trait loci (eQTL) analyses, ZNF804A-induced pathway alterations in neural cells and changes in synaptic phenotypes associated with ZNF804A expression. Based on these data, we hypothesize a potential biological mechanism for a genetic risk allele of ZNF804A in schizophrenia pathogenesis. We also review the efforts being made to characterize the affected intermediate phenotypes using neuroimaging and neuropsychological approaches. We then discuss additional common and rare ZNF804A variants in schizophrenia susceptibility and the potential genetic heterogeneity of these genomic loci between Europeans and Asians. This review for we believe the first time systematically presents the evidence for ZNF804A, describing its discovery and likely roles in brain development and schizophrenia pathogenesis. We believe that this work has summarized this information with a systemic and broad assessment of recent findings.Molecular Psychiatry advance online publication, 14 March 2017; doi:10.1038/mp.2017.19.

  17. The Risks to Patient Privacy from Publishing Data from Clinical Anesthesia Studies.

    O'Neill, Liam; Dexter, Franklin; Zhang, Nan

    2016-06-01

    In this article, we consider the privacy implications of posting data from small, randomized trials, observational studies, or case series in anesthesia from a few (e.g., 1-3) hospitals. Prior to publishing such data as supplemental digital content, the authors remove attributes that could be used to re-identify individuals, a process known as "anonymization." Posting health information that has been properly "de-identified" is assumed to pose no risks to patient privacy. Yet, computer scientists have demonstrated that this assumption is flawed. We consider various realistic scenarios of how the publication of such data could lead to breaches of patient privacy. Several examples of successful privacy attacks are reviewed, as well as the methods used. We survey the latest models and methods from computer science for protecting health information and their application to posting data from small anesthesia studies. To illustrate the vulnerability of such published data, we calculate the "population uniqueness" for patients undergoing one or more surgical procedures using data from the State of Texas. For a patient selected uniformly at random, the probability that an adversary could match this patient's record to a unique record in the state external database was 42.8% (SE < 0.1%). Despite the 42.8% being an unacceptably high level of risk, it underestimates the risk for patients from smaller states or provinces. We propose an editorial policy that greatly reduces the likelihood of a privacy breach, while supporting the goal of transparency of the research process.

  19. Throwing the baby out with the bath water: is it time for clinical judgment to supplement actuarial risk assessment?

    Abbott, Brian R

    2011-01-01

    The assessment of the potential for sexual violence is one of three prongs that must be met to satisfy the requirements for civil confinement of dangerous sex offenders in the 21 U.S. jurisdictions that have these laws. In a recent issue of The Journal, Sreenivasan et al. argued that, because of a host of methodological problems, actuarial risk assessment methods in general and the Static-99 and its progeny in particular are insufficient for accurate assessment of risk for dangerous sex offenders. They propose using a combination of clinical judgment with actuarial science as a solution. This analysis and review of Sreenivasan et al. reveals and corrects flaws in the arguments they employed to support their position and shows how the combination of actuarial science with clinical judgment is more error prone than the actuarial approach only, and cannot be forensically defended in court. Recommendations on reporting Static-99R data in expert testimony are provided, taking into account the limitations of the instrument.

    The prevalence of asthma is increasing, especially among children in Malaysia, with environmental factors as one of the main preventable contributors. The aim of this study was to determine the association between environmental air pollutants and the occurrence of asthma among children seen in pediatric clinics in Universiti Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur. An unmatched case control study among children who attended the pediatric clinic was carried out from May to August 2015. A total of 223 children who were diagnosed with asthma (105 cases) and who did not have asthma (118 controls) were included in this study. Their parents or caregivers were interviewed using questionnaires modified from the International Study of Asthma and Allergies in Childhood. Data obtained were analyzed using SPSS software version 20. There was a higher risk of asthma in those who had carpet at home (OR = 2.15 CI [1.25-3.68]), those who lived within 200 m of heavy traffic (OR = 1.72 CI [1.01-2.93]), and those who were exposed to lorry fumes (OR = 2.61. CI [1.38-4.93]). Environmental air pollutants increased the risk of asthma among children in Malaysia. Exposure to congested roads, lorry fumes, and indoor carpet were associated with asthma among children in this study. Parents or caretakers of children with asthma should be given adequate education on the prevention of asthmatic attack among these children.

    AIM: To determine the prevalence of a family history suggestive of Lynch syndrome (LS) among patients with colorectal cancer (CRC) followed in a coloproctology outpatient clinic in Southern Brazil.METHODS: A consecutive sample of patients with CRC were interviewed regarding personal and family histories of cancer. Clinical data and pathology features of the tumor were obtained from chart review.RESULTS: Of the 212 CRC patients recruited, 61 (29%)reported a family history of CRC, 45 (21.2%) were diagnosed under age 50 years and 11 (5.2%) had more than one primary CRC. Family histories consistent with Amsterdam and revised Bethesda criteria for LS were identified in 22 (10.4%) and 100 (47.2%) patients,respectively. Twenty percent of the colorectal tumors had features of the high microsatellite instability phenotype,which was associated with younger age at CRC diagnosis and with Bethesda criteria (P < 0.001). Only 5.3% of the patients above age 50 years had been previously submitted for CRC screening and only 4% of patients with suspected LS were referred for genetic risk assessment.CONCLUSION: A significant proportion of patients with CRC were at high risk for LS. Education and training of health care professionals are essential to ensure proper management.

    Full Text Available Disease recurrence is frequent in high-risk neuroblastoma (NBL patients even after multimodality aggressive treatment [a combination of chemotherapy, surgical resection, local radiation therapy, autologous stem cell transplantation (ASCT and cis-retinoic acid (CRA]. Recent clinical studies have explored the use of monoclonal antibodies (mAbs that bind to disialoganglioside (GD2, highly expressed in NBL, as a means to enable immune effector cells to destroy NBL cells via antibody-dependent cell-mediated cytotoxicity (ADCC. Preclinical data indicate that ADCC can be more effective when appropriate effector cells are activated by cytokines. Clinical studies have pursued this by administering anti-GD2 mAb in combination with ADCC-enhancing cytokines (IL2 and GM-CSF, a regimen that has demonstrated improved cancer-free survival. More recently, early clinical studies have used a fusion protein that consists of the anti-GD2 mAb directly linked to IL2, and antitumor responses were seen in the Phase II setting. Analyses of genes that code for receptors that influence ADCC activity and Natural Killer (NK cell function [Fc Receptor (FcR, Killer Immunoglublin-like Receptor (KIR, and KIR-ligand (KIR-L] suggest patients with antitumor activity are more likely to have certain genotype profiles. Further analyses will need to be conducted to determine whether these genotypes can be used as predictive markers for favorable therapeutic outcome, thus potentially increasing the efficacy of mAb-mediated NK cell-based cancer immunotherapy.

    Since late 2015, an unprecedented outbreak of Zika virus is spreading quickly across Southern America. The large size of the current outbreak in The Americas will also result in an increase in Zika virus infections among travelers returning from endemic areas. We report five cases of imported Zika virus infection to The Netherlands. Although the clinical course is usually mild, establishing the diagnosis is important, mainly because of the association with congenital microcephaly and the possibility of sexual transmission.

  4. The impact on work-related stress of mental health teams following team-based learning on clinical risk management.

    Sharkey, S B; Sharples, A

    2003-02-01

    Risk management is viewed as a systematic process based on multiprofessional and multi-agency decision-making. A learning pack was developed as part of a team-based learning project aiming to encourage and develop collaborative working practice. This brought different professionals and agencies working in mental health together to learn. There is little doubt that mental health practice is a source of stress for practitioners. Apart from the stress associated with managing 'risky' situations, risk management is also a relatively new concept. This can increase stress around ability to cope, both on an individual practitioner level and in teams. This article reports the impact that the learning pack had on team members' stress, specifically work-related stress. A range of scales were used to measure change in stress and results demonstrated reduced work-related pressure in a number of areas following the learning. The implications for team learning in relation to clinical risk management are discussed in light of the findings.

    During the last several last decades, reduction in lipids has been the main focus to decrease the risk of coronary heart disease (CHD). Several lines of evidence, however, have indicated that lipids account only for the PLA(2)) is a novel inflammatory biomarker that can provide much needed information about plaque inflammation and plaque stability. Lp-PLA(2) is among the multiple biomarkers that have been associated with increased CHD risk. In this present work, we review the evidence from previous studies addressing the effect of different therapies on decreasing Lp-PLA(2) and the role of direct Lp-PLA(2) inhibitors. This work also briefly reviews the evidence of Lp-PLA(2) clinical utility as a potential marker of vascular inflammation and formation of rupture prone plaques. Additionally, we also discuss the implication of available evidence in context of current cardiovascular inflammatory biomarkers recommendations and the evidence from epidemiologic studies addressing the relationship of Lp-PLA(2) and risk of cardiovascular disease.

  6. Air pollution, a rising environmental risk factor for cognition, neuroinflammation and neurodegeneration: The clinical impact on children and beyond.

    2016-01-01

    Air pollution (indoors and outdoors) is a major issue in public health as epidemiological studies have highlighted its numerous detrimental health consequences (notably, respiratory and cardiovascular pathological conditions). Over the past 15 years, air pollution has also been considered a potent environmental risk factor for neurological diseases and neuropathology. This review examines the impact of air pollution on children's brain development and the clinical, cognitive, brain structural and metabolic consequences. Long-term potential consequences for adults' brains and the effects on multiple sclerosis (MS) are also discussed. One challenge is to assess the effects of lifetime exposures to outdoor and indoor environmental pollutants, including occupational exposures: how much, for how long and what type. Diffuse neuroinflammation, damage to the neurovascular unit, and the production of autoantibodies to neural and tight-junction proteins are worrisome findings in children chronically exposed to concentrations above the current standards for ozone and fine particulate matter (PM2.5), and may constitute significant risk factors for the development of Alzheimer's disease later in life. Finally, data supporting the role of air pollution as a risk factor for MS are reviewed, focusing on the effects of PM10 and nitrogen oxides.

    Full Text Available Introduction: Neodymium:yttrium aluminum garnet (Nd:YAG laser resection is one of the most established interventional pulmonology techniques for immediate debulking of malignant central airway obstruction (CAO. The major aim of this study was to investigate the complication rate and identify clinical risk factors for complications in patients with advanced lung cancer. Methods: In the period from January 2006 to January 2011, data sufficient for analysis were identified in 464 patients. Nd:YAG laser resection due to malignant CAO was performed in all patients. The procedure was carried out in general anesthesia. Complications after laser resection were defined as severe hypoxemia, global respiratory failure, arrhythmia requiring treatment, hemoptysis, pneumothorax, pneumomediastinum, pulmonary edema, tracheoesophageal fistulae, and death. Risk factors were defined as acute myocardial infarction within 6 months before treatment, hypertension, chronic arrhythmia, chronic obstructive pulmonary disease (COPD, stabilized cardiomyopathy, previous external beam radiotherapy, previous chemotherapy, and previous interventional pulmonology treatment. Results : There was 76.1% male and 23.9% female patients in the study, 76.5% were current smokers, 17.2% former smokers, and 6.3% of nonsmokers. The majority of patients had squamous cell lung cancer (70%, small cell lung cancer was identified in 18.3%, adenocarcinoma in 3.4%, and metastases from lung primary in 8.2%. The overall complication rate was 8.4%. Statistically significant risk factors were age (P = 0.001, current smoking status (P = 0.012, arterial hypertension (P < 0.0001, chronic arrhythmia (P = 0.034, COPD (P < 0.0001, and stabilized cardiomyopathy (P < 0.0001. Independent clinical risk factors were age over 60 years (P = 0.026, arterial hypertension (P < 0.0001, and COPD (P < 0.0001. Conclusion : Closer monitoring of patients with identified risk factors is advisable prior and immediately after

    2014-01-01

    Puerto Rico (PR) has a large and rapidly growing population of people living with HIV. However, relatively little behavioral or clinical research has been done in this population. As treatment for HIV increasingly moves into a chronic condition model, it is becoming increasingly important to understand the needs of this population so critical social and behavioral interventions can be developed, thus enabling the individual and community-level benefits of antiretroviral (ARV) treatment to be fully realized. To date, however, there has been very little research on the mental health needs of people living with HIV in PR, a fact that constrains intervention development and implementation. This paper describes data from a public sexually transmitted infection (STI) and HIV clinic study in the San Juan metropolitan area between April 2010 and December 2012 (n = 1185), roughly a third (36%) of whom are living with HIV. Descriptive statistics, chi-square, t-tests, and binary logistic regressions were used to assess associations between HIV status and a history of suicide attempt. The overall prevalence of a history of suicide attempt was 20.4%. No statistically significant relationship was found between a history of suicide attempt and being HIV positive, although people with HIV infection did evidence a higher prevalence of attempts than HIV-negative subjects (23.4% vs. 19.0%). Factors associated with having a history of suicide attempt within the overall sample included gender, current employment status, a lifetime history of drug use, and a lifetime history of sex work. Similar patterns were seen in the HIV-positive subsample. There was a nonsignificant trend toward increased risk for a post-diagnosis suicide attempt. These findings suggest that additional research on mental health risks among populations at risk for HIV in PR is needed.

  9. Age and regional differences in clinical presentation and risk of hospitalization for dengue in Brazil, 2000-2014

    Marcelo N. Burattini

    Full Text Available OBJECTIVES: Dengue cases range from asymptomatic to severe, eventually leading to hospitalization and death. Timely and appropriate management is critical to reduce morbidity. Since 1980, dengue has spread throughout Brazil, affecting an increasing number of individuals. This paper describes age and regional differences in dengue’s clinical presentation and associated risk of hospitalization based on more than 5 million cases reported to the Brazilian Ministry of Health from 2000-2014. METHODS: We performed a retrospective analysis of ∼5,450,000 dengue cases, relating clinical manifestations and the risk of hospitalization to age, gender, previous infection by dengue, dengue virus serotype, years of formal education, delay to first attendance and the occurrence of dengue during outbreaks and in different Brazilian regions. RESULTS: Complicated forms of dengue occurred more frequently among those younger than 10 years (3.12% vs 1.92% and those with dengue virus 2 infection (7.65% vs 2.42%, with a delay to first attendance >2 days (3.18% vs 0.82% and with ≤4 years of formal education (2.02% vs 1.46%. The risk of hospitalization was higher among those aged 6-10 years old (OR 4.57; 95% CI 1.43-29.96 and those who were infected by dengue virus 2 (OR 6.36; 95% CI 2.52-16.06, who lived in the Northeast region (OR 1.38; 95% CI 1.11-2.10 and who delayed first attendance by >5 days (composite OR 3.15; 95% CI 1.33-8.9. CONCLUSIONS: In Brazil, the occurrence of severe dengue and related hospitalization is associated with being younger than 10 years old, being infected by dengue virus 2 or 3, living in the Northeast region (the poorest and the second most populated and delaying first attendance for more than 2 days.

    Full Text Available Background: In the past few years, the interest in STDs and their management has increased tremendously because of their proven role in facilitation of HIV infection, which, in turn, also increases the risk of acquiring STIs. Sexually transmitted diseases (STDs are a major health problem affecting mostly young people, not only in developing, but also in developed countries Male circumcision is being considered as strategy to reduce the burden of HIV/AIDS. Aims: (i To screen the new patients attending the STI clinic for bacterial causes of STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum and Gardnerella vaginalis and (ii to evaluate the role of various risk factors in the prevalence of STIs. Materials and Methods: The present study was conducted on 200 patients attending the STI clinic. They were evaluated for the prevalence of HIV and bacterial STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum and Gardnerella vaginalis along with the role of risk factors particularly circumcision. Results: The prevalence of HIV was 7% and prevalence of other STI was 20%. The causative agents were Chlamydia 8%, Gonorrhea 7.5%, Bacterial Vaginosis 2.7% and Syphilis 2%. Conclusion: The factors found to be significantly associated with the prevalence of STI were circumcision, positive HIV status, education, religion, multiple sexual partners, contact with Commercial sex workers (CSW, non use of contraception, profession involving long stay away from home, and past history of STI. The present study suggests that circumcision is a protective factor for acquisition of STIs but other factors like sexual behavior, use of barrier contraceptives, drug abuse etc., also play a role.

    2009-01-01

    Full Text Available Background: Reports from India on the prevalence and determinants of female sexual dysfunction (FSD are scant. Aims: To determine the prevalence and risk factors for FSD. Settings and Design: A cross-sectional survey in a medical outpatient clinic of a tertiary care hospital. Materials and Methods: We administered a Tamil version of the Female Sexual Function Index (FSFI to 149 married women. We evaluated putative risk factors for FSD. We elicited participant′s attributions for their sexual difficulties. Statistical Analysis: We estimated the prevalence of possible FSD and sexual difficulties from published FSFI total and domain cut-off scores. We used logistic regression to identify risk factors for possible FSD. Results: FSFI total scores suggested FSD in two-thirds of the 149 women (73.2%; 95% confidence intervals [CI] 65.5% to 79.6%. FSFI domain scores suggested difficulties with desire in 77.2%; arousal in 91.3%; lubrication in 96.6%; orgasm in 86.6%, satisfaction in 81.2%, and pain in 64.4%. Age above 40 years (odds ratios [OR] 11.7; 95% CI 3.4 to 40.1 and fewer years of education (OR 1.2; 95% CI 1.0 to 1.3 were identified by logistic regression as contributory. Women attributed FSD to physical illness in participant or partner, relationship problems, and cultural taboos but none had sought professional help. Conclusions: Sexual problems suggestive of dysfunction, as suggested by FSFI total and domain scores, are highly prevalent in the clinic setting, particularly among women above 40 and those less educated, but confirmation using locally validated cut-off scores of the FSFI is needed.

    Degreef, Ilse; Steeno, Pieter; De Smet, Luc

    2008-08-01

    Dupuytren's disease is very common, with a prevalence of up to 40% in the Scandinavian population. Although many epidemiological surveys have been conducted, little is known about its aetiology. Multiple risk factors in Dupuytren's disease have been identified. About 80% of the affected patients are male. Even though recent data suggest similar outcome after surgical treatment in the female patient, recurrence after surgery is more frequent. To assess Dupuytren's disease in women, a record analysis and a survey of risk factors was conducted in 130 female patients surgically treated at our institution between 1988 and 2005. With a response rate of 52%, 65 women were included (6 patients were confirmed dead). The mean age of onset of the disease was 50 years and 6 months. After a mean follow-up of 7 years and 7 months (2y1m to 21y9m), recurrent disease after surgery was reported in 42%. Bilateral disease was present in 54%, unilateral in 26% right and 20% left hands. The fifth finger was involved in 77%, the 4th finger in 48% and the 1st ray in 14%. Ectopic lesions were seen in 19%, with a positive family history in 55%. Only one patient had a confirmed alcohol abuse; 22% were smokers. There were 32% manual workers. Shoulder pain was present in 54% of the patients, with confirmed diagnosis of frozen shoulder syndrome in 45%. High cholesterol was diagnosed in 39% and only 6% had diabetes. Epilepsy was seen in 5%. High disease recurrence and factors related to an aggressive course of the disease are present in female patients with Dupuytren's contracture, with a high family history occurrence, bilateral disease and associated Ledderhose disease. Several known risk factors were present: high cholesterol, smoking and manual work. Frozen shoulder showed a very high prevalence in women with Dupuytren's disease.

    Full Text Available Abstract Background It is unclear why some children with acute otitis media (AOM have poor outcomes. Our aim was to describe the clinical course of AOM and the associated bacterial nasopharyngeal colonisation in a high-risk population of Australian Aboriginal children. Methods We examined Aboriginal children younger than eight years who had a clinical diagnosis of AOM. Pneumatic otoscopy and video-otoscopy of the tympanic membrane (TM and tympanometry was done every weekday if possible. We followed children for either two weeks (AOM without perforation, or three weeks (AOM with perforation, or for longer periods if the infection persisted. Nasopharyngeal swabs were taken at study entry and then weekly. Results We enrolled 31 children and conducted a total of 219 assessments. Most children had bulging of the TM or recent middle ear discharge at diagnosis. Persistent signs of suppurative OM (without ear pain were present in most children 7 days (23/30, 77%, and 14 days (20/26, 77% later. Episodes of AOM did not usually have a sudden onset or short duration. Six of the 14 children with fresh discharge in their ear canal had an intact or functionally intact TM. Perforation size generally remained very small (Streptococcus pneumoniae (82%, Haemophilus influenzae (71%, and Moraxella catarrhalis (95%; 63% of swabs cultured all three pathogens. Conclusion In this high-risk population, AOM was generally painless and persistent. These infections were associated with persistent bacterial colonisation of the nasopharynx and any benefits of antibiotics were modest at best. Systematic follow up with careful examination and review of treatment are required and clinical resolution cannot be assumed.

In this naturalistic study we investigated a sample of 809 antipsychotic-treated patients from Swedish psychosis outpatient teams. Cardiovascular risk factors (eg, metabolic syndrome, homeostasis model assessment of insulin resistance, and low-density lipoprotein values were measured, and their associations to current antipsychotic pharmacotherapy were studied. Ten antipsychotic drugs were compared in a stepwise logistic regression model. For the patients, the presence of the components of metabolic syndrome ranged from 35% for hyperglycemia to 64% for elevated waist circumference. Hypertriglyceridemia was associated with clozapine (odds ratio [OR] = 1.81, 95% confidence interval [CI] 1.08–3.04, reduced high-density lipoprotein with both clozapine and olanzapine (OR = 1.73, 95% CI 1.01–2.97; and OR = 2.03, 95% CI 1.32–3.13, hypertension with perphenazine (OR = 2.00, 95% CI 1.21–3.59, and hyperglycemia inversely with ziprasidone (OR = 0.21, 95% CI 0.05–0.89 and positively with haloperidol (OR = 2.02, 95% CI 1.18–3.48.

    Full Text Available This review discusses issues related to intensive care in recipients of transplanted liver in the early postoperative period, with an emphasis on contemporary conditions and attitudes that are specific for this group of patients. Early allograft dysfunction (EAD requires immediate diagnosis and appropriate treatment in case. The causes of the EAD and therapeutic tactics are discussed. Acute kidney injury (AKI and renal failure are common in patients after transplantation. We consider etiology, risk factors, diagnosis and treatment guidelines for AKI. The negative impact of EAD and AKI on the grafts survival and recipients is demonstrated. 

  17. The genetic basis of Lynch syndrome and its implications for clinical practice and risk management.

    Cohen, Stephanie A; Leininger, Anna

    2014-01-01

    Lynch syndrome is the most common cause of hereditary colon cancer, and accounts for as much as 3% of all colon and endometrial cancers. The identification and management of individuals with Lynch syndrome have evolved over the past 20 years, yet the syndrome remains vastly underdiagnosed. It is important for clinicians to recognize individuals and families who are at risk in order to be able to manage them appropriately and reduce their morbidity and mortality from this condition. This review will touch on the history of Lynch syndrome, the current knowledge of genotype-phenotype correlations, the cancers associated with Lynch syndrome, and management of individuals who are gene carriers.

    Objective The purpose of this study was to evaluate the prognosis according to the number of high risk factors in patients with high risk factors after radical hysterectomy and adjuvant chemoradiation therapy for early stage cervical cancer. Methods Clinicopathological variables and clinical outcomes of patients with FIGO (International Federation of Gynecology and Obstetrics) stage IB1 to IIA cervical cancer who had one or more high risk factors after radical hysterectomy and adjuvant chemoradiation therapy were retrospectively analyzed. Patients were divided into two groups according to the number of high risk factors (group 1, single high risk factor; group 2, two or more high risk factors). Results A total of 93 patients were enrolled in the present study. Forty nine out of 93 (52.7%) patients had a single high risk factor, and 44 (47.3%) had two or more high risk factors. Statistically significant differences in stage and stromal invasion were observed between group 1 and group 2. However, age, histology, tumor size, and lymphovascular space invasion did not differ significantly between the groups. Distant recurrence occurred more frequently in group 2, and the probability of recurrence and death was higher in group 2. Conclusion Patients with two or more high risk factors had worse prognosis in early stage cervical cancer. For these patients, consideration of new strategies to improve survival may be worthwhile. Conduct of further clinical trials is warranted for development of adjuvant treatment strategies individualized to each risk group. PMID:27200308

    The onset of schizophrenia is typically preceded by a prodromal period lasting several years during which sub-threshold symptoms may be identified retrospectively. Clinical interviews are currently used to identify individuals who have an ultra-high risk (UHR) of developing a psychotic illness with a view to provision of interventions that prevent, delay or reduce severity of future mental health issues. The utility of bio-markers as an adjunct in the identification of UHR individuals is not yet established. Several event-related potential measures, especially mismatch-negativity (MMN), have been identified as potential biomarkers for schizophrenia. In this 12-month longitudinal study, demographic, clinical and neuropsychological data were acquired from 102 anti-psychotic naive UHR and 61 healthy controls, of whom 80 UHR and 58 controls provided valid EEG data during a passive auditory task at baseline. Despite widespread differences between UHR and controls on demographic, clinical and neuropsychological measures, MMN and P3a did not differ between these groups. Of 67 UHR at the 12-month follow-up, 7 (10%) had transitioned to a psychotic illness. The statistical power to detect differences between those who did or did not transition was limited by the lower than expected transition rate. ERPs did not predict transition, with trends in the opposite direction to that predicted. In exploratory analysis, the strongest predictors of transition were measures of verbal memory and subjective emotional disturbance. PMID:28187217

    The incidental detection of small lung nodules in children is a vexing consequence of an increased reliance on CT. We present an algorithm for the management of lung nodules detected on CT in children, based on the presence or absence of symptoms, the presence or absence of elements in the clinical history that might explain these nodules, and the imaging characteristics of the nodules (such as attenuation measurements within the nodule). We provide suggestions on how to perform a thoughtfully directed and focused search for clinically occult extrathoracic disease processes (including malignant disease) that may present as an incidentally detected lung nodule on CT. This algorithm emphasizes that because of the lack of definitive information on the natural history of small solid nodules that are truly detected incidentally, their clinical management is highly dependent on the caregivers' individual risk tolerance. In addition, we present strategies to reduce the prevalence of these incidental findings, by preventing unnecessary chest CT scans or inadvertent inclusion of portions of the lungs in scans of adjacent body parts. Application of these guidelines provides pediatric radiologists with an important opportunity to practice patient-centered and evidence-based medicine. (orig.)

    2014-01-01

    Full Text Available Osteogenesis imperfecta (OI is a rare hereditary condition caused by changes in collagen metabolism. It is classified into four types according to clinical, genetic, and radiological criteria. Clinically, bone fragility, short stature, blue sclerae, and locomotion difficulties may be observed in this disease. OI is often associated to severe dental problems, such as dentinogenesis imperfecta (DI and malocclusions. Radiographically, affected teeth may have crowns with bulbous appearance, accentuated constriction in the cementoenamel junction, narrowed roots, large root canals due to defective dentin formation, and taurodontism (enlarged pulp chambers. There is no definitive cure, but bisphosphonate therapy is reported to improve bone quality; however, there is a potential risk of bisphosphonate-related osteonecrosis of the jaw. In this study we report a case of OI in a male pediatric patient with no family history of OI who was receiving ongoing treatment with intravenous perfusion of bisphosphonate and who required dental surgery. In addition, we discussed the clinical and imaging findings and briefly reviewed the literature.

    Purpose: To report on acute toxicity, longitudinal cognitive function, and early clinical outcomes in children with average-risk medulloblastoma. Methods and Materials: Twenty children {>=}5 years of age classified as having average-risk medulloblastoma were accrued on a prospective protocol of hyperfractionated radiation therapy (HFRT) alone. Radiotherapy was delivered with two daily fractions (1 Gy/fraction, 6 to 8 hours apart, 5 days/week), initially to the neuraxis (36 Gy/36 fractions), followed by conformal tumor bed boost (32 Gy/32 fractions) for a total tumor bed dose of 68 Gy/68 fractions over 6 to 7 weeks. Cognitive function was prospectively assessed longitudinally (pretreatment and at specified posttreatment follow-up visits) with the Wechsler Intelligence Scale for Children to give verbal quotient, performance quotient, and full-scale intelligence quotient (FSIQ). Results: The median age of the study cohort was 8 years (range, 5-14 years), representing a slightly older cohort. Acute hematologic toxicity was mild and self-limiting. Eight (40%) children had subnormal intelligence (FSIQ <85), including 3 (15%) with mild mental retardation (FSIQ 56-70) even before radiotherapy. Cognitive functioning for all tested domains was preserved in children evaluable at 3 months, 1 year, and 2 years after completion of HFRT, with no significant decline over time. Age at diagnosis or baseline FSIQ did not have a significant impact on longitudinal cognitive function. At a median follow-up time of 33 months (range, 16-58 months), 3 patients had died (2 of relapse and 1 of accidental burns), resulting in 3-year relapse-free survival and overall survival of 83.5% and 83.2%, respectively. Conclusion: HFRT without upfront chemotherapy has an acceptable acute toxicity profile, without an unduly increased risk of relapse, with preserved cognitive functioning in children with average-risk medulloblastoma.

  4. Use of information: environmental standards, assessments of risk, prevention and clinical implications.

    Becklake, M R

    1985-07-22

    Information which relates morbidity or mortality to environmental conditions (exposure-response relationships) forms the basis for public health as well as for clinical action. For both types of action, the information base is the same, neither complete nor comprehensive. So, both types of action are based on hypothesis, the best available to explain the facts, but subject to review in the light of new facts. Even though the volume of information may be considerable, as in the case of asbestos, there are always gaps in knowledge to be bridged by judgement. This should be made on the basis of as complete an evaluation as possible of all the available evidence.

    Research in individuals at clinical high-risk (CHR) for psychosis has focused on subjects with no more than 12 months of present or worsened attenuated positive symptoms. However, the impact of long duration attenuated positive and/or negative prodromal symptoms on outcomes is unclear. Seventy-six CHR subjects with attenuated positive symptoms and at least moderate severity level negative symptoms rated on the Scale of Prodromal Symptoms (SOPS) were prospectively followed for a mean of 3.0 ± 1.6 years. Social and Role functioning was assessed with the Global Functioning: Social and Role scales. Correlations between attenuated positive and negative symptom duration and severity and conversion to psychosis and functional outcomes were analyzed. The average onset of SOPS rated negative symptoms (M = 53.24 months, SD = 48.90, median = 37.27) was approximately twelve months prior to the emergence of attenuated positive symptom (M = 40.15 months, SD = 40.33, median = 24.77, P negative (P = 0.754) symptoms, predicted conversion to psychosis. Neither positive symptom duration (P = 0.181) nor severity (P = 0.469) predicted role or social functioning at study endpoint. Conversely, longer negative symptom duration predicted poor social functioning (P = 0.004). Overall, our findings suggest that the severity of attenuated positive symptoms at baseline may be more important than symptom duration for determining individuals at increased risk of developing psychosis. In contrast, long-standing negative symptoms may be associated with persistent social difficulties and therefore have an important position in the treatment of disability.

  6. Cutaneous and Mucosal Lichen Planus: A Comprehensive Review of Clinical Subtypes, Risk Factors, Diagnosis, and Prognosis

    2014-01-01

    Full Text Available Lichen planus (LP is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as esophageal or ophthalmological involvement are underdiagnosed. The burden of the disease is higher in some variants including hypertrophic LP and erosive oral LP, which may have a more chronic pattern. LP can significantly affect the quality of life of patients as well. Drugs or contact allergens can cause lichenoid reactions as the main differential diagnosis of LP. LP is a T-cell mediated immunologic disease but the responsible antigen remains unidentified. In this paper, we review the history, epidemiology, and clinical subtypes of LP. We also review the histopathologic aspects of the disease, differential diagnoses, immunopathogenesis, and the clinical and genetic correlations.

    The implications of low triiodothyronine syndrome (LT3S) in patients with radiation enteritis (RE) have not been properly investigated. As such, we conducted this cohort study to investigate the association between LT3S and RE, to explore the etiology of LT3S in RE, to evaluate the clinical features and clinical outcomes of LT3S patients, and to inspect the correlation of clinical variables and LT3S in RE.This prospective study included 39 RE patients. Medical records and various laboratory parameters (including thyroidal, tumorous, nutritional, and radiotherapy variables) were collected in all participants.Our results showed that the incidence of LT3S was 84.6% in patients with RE. Total protein (71.7 ± 5.7 vs 63.2 ± 9.6 g/L, P = 0.04) and albumin (ALB, 46.0 ± 4.6 vs 38.7 ± 5.3 g/L, P = 0.01) were significantly lower in LT3S group compared with those in euthyroid group. Standard thyroid-stimulating hormone index (-0.89 ± 2.11 vs -2.39 ± 1.33, P = 0.03) and sum activity of deiodinases (19.74 ± 4.19 vs 12.55 ± 4.32 nmol/L, P = 0.01) were significantly lower in LT3S group. Patients with LT3S suffered longer duration of hospitalization (48.25 ± 23.29 days in LT3S vs 26.75 ± 10.56 days in euthyroid, P = 0.036). Low serum ALB (β = 0.694, 95% CI = 0.007-0.190, P = 0.037) was the only significant predictor of LT3S.LT3S was common in RE patients. A hypodeiodination condition and a potential pituitary-thyrotroph dysfunction might play a role in the pathophysiology of LT3S in RE. Worse nutritional status and clinical outcomes were confirmed in RE patients with LT3S. Furthermore, total protein and ALB were observed as protective and differentiating parameters of LT3S in RE. In summary, this was the 1st investigation to evaluate the clinical correlation between RE and LT3S, investigate the prevalence of LT3S in RE, and explore the pathogenesis of LT3S, despite the limitation of a

  9. Adapting existing natural language processing resources for cardiovascular risk factors identification in clinical notes.

    Khalifa, Abdulrahman; Meystre, Stéphane

    2015-12-01

    The 2014 i2b2 natural language processing shared task focused on identifying cardiovascular risk factors such as high blood pressure, high cholesterol levels, obesity and smoking status among other factors found in health records of diabetic patients. In addition, the task involved detecting medications, and time information associated with the extracted data. This paper presents the development and evaluation of a natural language processing (NLP) application conceived for this i2b2 shared task. For increased efficiency, the application main components were adapted from two existing NLP tools implemented in the Apache UIMA framework: Textractor (for dictionary-based lookup) and cTAKES (for preprocessing and smoking status detection). The application achieved a final (micro-averaged) F1-measure of 87.5% on the final evaluation test set. Our attempt was mostly based on existing tools adapted with minimal changes and allowed for satisfying performance with limited development efforts.

    2000-01-01

    The nursing team at the University of São Paulo Hospital has implemented actions directed to parents, such as support groups, training for hospital discharge and their involvement in the progressive care to their children. Aiming at expanding such care, the authors have implemented a support program involving ludic and recreational activities with the parents of hospitalized preterm babies under risk. The account of this experience is the object of this work. The interventions were performed by a group of nursing students who gather with the parents weekly for a period of two hours and develop group-dynamics techniques; leisure activities; creativity workshops involving manual work and discussions on themes concerning personal and environmental hygiene. Through these new care strategies directed to parents, the authors expect to contribute to the process of construction of more integral and humanized care in the area of neonatology by focusing on the family.

  11. Simulating the impact of improved cardiovascular risk interventions on clinical and economic outcomes in Russia.

    Kenny Shum

    Full Text Available OBJECTIVES: Russia faces a high burden of cardiovascular disease. Prevalence of all cardiovascular risk factors, especially hypertension, is high. Elevated blood pressure is generally poorly controlled and medication usage is suboptimal. With a disease-model simulation, we forecast how various treatment programs aimed at increasing blood pressure control would affect cardiovascular outcomes. In addition, we investigated what additional benefit adding lipid control and smoking cessation to blood pressure control would generate in terms of reduced cardiovascular events. Finally, we estimated the direct health care costs saved by treating fewer cardiovascular events. METHODS: The Archimedes Model, a detailed computer model of human physiology, disease progression, and health care delivery was adapted to the Russian setting. Intervention scenarios of achieving systolic blood pressure control rates (defined as systolic blood pressure <140 mmHg of 40% and 60% were simulated by modifying adherence rates of an antihypertensive medication combination and compared with current care (23.9% blood pressure control rate. Outcomes of major adverse cardiovascular events; cerebrovascular event (stroke, myocardial infarction, and cardiovascular death over a 10-year time horizon were reported. Direct health care costs of strokes and myocardial infarctions were derived from official Russian statistics and tariff lists. RESULTS: To achieve systolic blood pressure control rates of 40% and 60%, adherence rates to the antihypertensive treatment program were 29.4% and 65.9%. Cardiovascular death relative risk reductions were 13.2%, and 29.6%, respectively. For the current estimated 43,855,000-person Russian hypertensive population, each control-rate scenario resulted in an absolute reduction of 1.0 million and 2.4 million cardiovascular deaths, and a reduction of 1.2 million and 2.7 million stroke/myocardial infarction diagnoses, respectively. Averted direct costs from

    Lewis John Haddow

    Full Text Available BACKGROUND: Immune reconstitution inflammatory syndrome (IRIS is a widely recognised complication of antiretroviral therapy (ART, but there are still limited data from resource-limited settings. Our objective was to characterize the incidence, clinical spectrum, risk factors and contribution to mortality of IRIS in two urban ART clinics in South Africa. METHODS AND FINDINGS: 498 adults initiating ART in Durban, South Africa were followed prospectively for 24 weeks. IRIS diagnosis was based on consensus expert opinion, and classified by mode of presentation (paradoxical worsening of known opportunistic infection [OI] or unmasking of subclinical disease. 114 patients (22.9% developed IRIS (36% paradoxical, 64% unmasking. Mucocutaneous conditions accounted for 68% of IRIS events, mainly folliculitis, warts, genital ulcers and herpes zoster. Tuberculosis (TB accounted for 25% of IRIS events. 18/135 (13.3% patients with major pre-ART OIs (e.g. TB, cryptococcosis developed paradoxical IRIS related to the same OI. Risk factors for this type of IRIS were baseline viral load >5.5 vs. 30 days of OI treatment prior to ART (2.66; 1.16-6.09. Unmasking IRIS related to major OIs occurred in 25/498 patients (5.0%, and risk factors for this type of IRIS were baseline C-reactive protein ≥25 vs. 12 g/dL (3.36; 1.32-8.52, ≥10% vs. <10% weight loss prior to ART (2.31; 1.05-5.11 and mediastinal lymphadenopathy on pre-ART chest x-ray (9.15; 4.10-20.42. IRIS accounted for 6/25 (24% deaths, 13/65 (20% hospitalizations and 10/35 (29% ART interruptions or discontinuations. CONCLUSION: IRIS occurred in almost one quarter of patients initiating ART, and accounted for one quarter of deaths in the first 6 months. Priority strategies to reduce IRIS-associated morbidity and mortality in ART programmes include earlier ART initiation before onset of advanced immunodeficiency, improved pre-ART screening for TB and cryptococcal infection, optimization of OI therapy prior to ART

    2009-06-01

    A quasi-experimental study was conducted at a Dutch sexually transmitted infection (STI) clinic to compare the effects of educational counseling and motivational interviewing (MI)-based HIV/STI counseling on determinants of condom use and partner notification at 6-month follow-up. It also examined the feasibility of MI-based counseling in a busy real-life clinic. The counseling approaches were historically compared: respondents in the control condition were recruited between April and July 2005, those in the experimental condition between September and December 2005. The study involved 428 participants. These were all high-risk clients of the STI clinic. Their mean age was 33.7 years, and 39.6% were female. The study showed that MI-based counseling had a more positive effect on self-efficacy, intentions to use condoms with casual partners, and long-term condom use with steady partners. It had no adversarial outcomes on other social cognitions or behaviors compared to educational counseling. Furthermore, MI-based counseling is experienced as a more respectful and structured way of counseling. MI-based counseling was relatively easily implemented into the current clinic procedures. In addition to the implementation of the training, neither specialized staff nor additional or longer client visits were needed. However, some nurses indicated that the new method required more personal investment and effort. Limitations of the current study are the low response rates, the high educational level of most participants, and the small sample size regarding partner notification. Nonetheless, we conclude that MI-based counseling was a more effective approach to preventive counseling compared to educational counseling and feasible in the busy real-life setting.

    Objective: To investigate the effect of the nursing path on postoperative complications after endoscopic submucosal dissection (ESD). Method: Patients' nursing paths for ESD were established based on a systematic analysis of relevant literature, previous clinical procedures and consultation with chief physicians from a gastroenterology department. Forty patients were divided into the observation or control group and were assigned to follow the nursing path or the conventional path after an ESD, respectively. Next, the incidence of postoperative complications of these two groups was measured, primarily assessing the occurrences of bleeding, perforation, infection, and anxiety. Results: The incidence of complications after ESD in the observation group was remarkably lower than that of the control group (P Conclusion: The nursing path for ESD has a positive role in reducing certain frequent complications that occur after ESD, particularly infection and anxiety;in addition, the nursing path optimizes nursing care in patients with gastrointestinal stromal tumor.

    Full Text Available Acute kidney injury (AKI is frequently seen in Hemiscorpius lepturus scorpion stung children. We have previously reported several victims with hemolytic uremic syndrome (HUS and a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 deficiency. Hence, we conducted this study to identify predictive factors and clinical features of AKI in H. lepturus scorpion stung patients. We included all 215 H. lepturus scorpion stung children with no previous renal diseases in two groups (with and without AKI and compared them based on their clinical and laboratory findings. AKI was found in 27.4% of patients, they were significantly younger and with lower body weight (P = 0.006, P = 0.011, respectively. There was a significant difference between groups with and without AKI in findings such as fever (P = 0.003, hypertension (P <0.001, hemolytic anemia (P <0.001, thrombocytopenia (P <0.001, massive proteinuria (P <0.001, hemoglobinuria (P <0.001, pyuria (P <0.001, and hematuria (P = 0.004. HUS was in 5.5% and disseminated intravascular coagulation in 14.6% which had a significant association with AKI (P <0.001.There were several independent predictors for AKI in a multivariate regression model including thrombocytopenia (P = 0.002, pyuria (P = 0.01, proteinuria (P =0.01, and fever (P = 0.02. Hemodialysis was performed in four patients but kidney function improved in all patients and there was no findings of renal impairment after three months follow-up. We found several predictors for AKI in children following H. lepturus scorpion sting including younger age, delay in receiving medical care, pigmenturia, microangiopathic hemolytic anemia, proteinuria, and pyuria.

    The HPV-Risk assay is a novel real-time PCR assay targeting the E7 region of 15 high-risk human papillomavirus (HPV) types (i.e., HPV16, -18, -31, -33, -35, -39, -45, -51, -52, -56, -58, -59, -66, -67, and -68), and provides additional genotype information for HPV16 and HPV18. This study evaluated the clinical performance and reproducibility of the HPV-Risk assay with cervical scraping specimens and its utility with self-collected (cervico)vaginal specimens. The clinical performance of the HPV-Risk assay for cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) with cervical scraping specimens was evaluated by a noninferiority analysis, relative to high-risk HPV GP5+/6+ PCR, following international guidelines for HPV test requirements for cervical cancer screening. The HPV-Risk assay showed clinical sensitivity for CIN2+ of 97.1% (95% confidence interval [CI], 89.1 to 99.3%; 67/69 samples) and a clinical specificity for CIN2+ of 94.3% (95% CI, 92.5 to 95.7%; 777/824 samples). The clinical sensitivity and specificity were noninferior to those of GP5+/6+ PCR (noninferiority score test, P=0.006 and 0.0003, respectively). Intralaboratory reproducibility over time (99.5% [95% CI, 98.6 to 99.8%]; 544/547 samples, kappa=0.99) and interlaboratory agreement (99.2% [95% CI, 98.6 to 99.8%]; 527/531 samples, kappa=0.98) for the HPV-Risk assay with cervical scraping specimens were high. The agreement of the HPV-Risk assay results for self-collected (cervico)vaginal specimens and clinician-obtained cervical scraping specimens was also high, i.e., 95.9% (95% CI, 85.1 to 99.0%; 47/49 samples, kappa=0.90) for self-collected lavage samples and 91.6% (95% CI, 84.6 to 95.6%; 98/107 samples, kappa=0.82) for self-collected brush samples. In conclusion, the HPV-Risk assay meets the cross-sectional clinical and reproducibility criteria of the international guidelines for HPV test requirements and can be considered clinically validated for cervical screening purposes.

    Background: To investigate the clinical characteristics and analyze risk factors for severe respiratory syncytial virus (RSV) infection in hospitalized infants with acute lower respiratory tract infections (ALRIs). Methods: A retrospective review of the medical records of infants with RSV-associated ALRIs between March 1st, 2011 and February 29th, 2012 was conducted. Subjects were followed up over the phone or by outpatient visit six and twelve months after discharge. Results: Among 913 RSV-associated ALRIs infants, 288 (31.5%) had severe infections, which accounted for 4.2% of hospitalized children. The hospital RSV mortality rate was 1.0%. The proportions of cases with tachypnea, apnea, cyanosis, and fine rales were significantly higher in the severe ALRIs group (all P Conclusions: Younger age, low birth weight and underlying disease are associated with severe RSVassociated ALRIs. Furthermore, severe RSV infections may be associated with a higher frequency of subsequent bronchitis, pneumonia and re-hospitalization in the following year.

  1. Does the routine use of global coronary heart disease risk scores translate into clinical benefits or harms? A systematic review of the literature

    Crespo Eric

    2008-03-01

    Full Text Available Abstract Background Guidelines now recommend routine assessment of global coronary heart disease (CHD risk scores. We performed a systematic review to assess whether global CHD risk scores result in clinical benefits or harms. Methods We searched MEDLINE (1966 through June 13, 2007 for articles relevant to our review. Using predefined inclusion and exclusion criteria, we included studies of any design that provided physicians with global risk scores or allowed them to calculate scores themselves, and then measured clinical benefits and/or harms. Two reviewers reviewed potentially relevant studies for inclusion and resolved disagreement by consensus. Data from each article was then abstracted into an evidence table by one reviewer and the quality of evidence was assessed independently by two reviewers. Results 11 studies met criteria for inclusion in our review. Six studies addressed clinical benefits and 5 addressed clinical harms. Six studies were rated as "fair" quality and the others were deemed "methodologically limited". Two fair quality studies showed that physician knowledge of global CHD risk is associated with increased prescription of cardiovascular drugs in high risk (but not all patients. Two additional fair quality studies showed no effect on their primary outcomes, but one was underpowered and the other focused on prescribing of lifestyle changes, rather than drugs whose prescribing might be expected to be targeted by risk level. One of these aforementioned studies showed improved blood pressure in high-risk patients, but no improvement in the proportion of patients at high risk, perhaps due to the high proportion of participants with baseline risks significantly exceeding the risk threshold. Two fair quality studies found no evidence of harm from patient knowledge of global risk scores when they were accompanied by counseling, and optional or scheduled follow-up. Other studies were too methodologically limited to draw conclusions

    Full Text Available Toxocarosis is a widespread zoonosis caused by the ascarid nematodes Toxocara canis and Toxocara cati, which primarily infect dogs and cats, respectively. Most human infections with Toxocara are asymptomatic; however, some infected individuals may develop a serious illness and even death. Nevertheless, epidemiological knowledge regarding the prevalence and risks associated with Toxocara infection is limited in China. Therefore, we performed a cross-sectional pilot study and estimated the seroprevalence of Toxocara infection in humans in Shandong Province, eastern China for the first time, from June 2011 to July 2013, involving clinically healthy individuals, pregnant women and psychiatric patients, aiming to attract public attention to Toxocara infection.Seroprevalence of Toxocara was determined using an enzyme-linked immunosorbent assay based on a cross-sectional study conducted in Qingdao and Weihai, Shandong Province, eastern China. Factors potentially associated with Toxocara infection were identified by logistic regression analysis. The overall Toxocara seroprevalence among the study population (n = 2866 was 12.25%, and a significantly higher seroprevalence in psychiatric patients (16.40%, 73/445 than that in clinically healthy individuals (13.07%, 187/1431 and pregnant women (9.19%, 91/990 was revealed. Univariate analyses suggested that keeping dogs at home (OR = 0.06, 95% CI 0.05-0.08, P<0.001, contact with cats and dogs (OR = 0.42, 95% CI 0.33-0.53, P<0.001 and exposure with soil (OR = 0.37, 95% CI 0.28-0.49, P<0.001 were risk factors associated with Toxocara infection.The present study revealed, for the first time, that human infection with Toxocara is common in eastern China, posing a significant public health concern. Increasing human and dog populations, population movements and climate change all will serve to increase the importance of this zoonosis. Further studies under controlled conditions are necessary to define potential

    Full Text Available OBJECTIVE: To investigate the clinical features, outcome, and risk factors of disease flares in patients with pregnancy-related lupus (PRL. METHODS: Medical charts of 155 consecutive PRL inpatients were systematically reviewed, including demographic data, clinical features, laboratory findings, treatment, complications, and outcome. RESULTS: PRL cases were divided into active (a-PRL (n = 82, 53.0% and stable lupus (s-PRL (n = 73, 47.0%. Compared with nonpregnant active female systemic lupus erythematosus (SLE patients, a-PRL including new-onset lupus (n-PRL and flare lupus (f-PRL (n = 41 respectively, had a higher incidence of renal and hematological involvement but less mucocutaneous and musculoskeletal involvement (p<0.05. The incidence of preeclampsia/eclampsia, fetal loss, and preterm birth were significantly higher in a-PRL than in s-PRL (p<0.05. Despite receiving a more vigorous glucocorticoid treatment, a-PRL mothers had a poorer prognosis (p<0.001. Five (6.1% of them died and 13 (15.9% developed severe irreversible organ failure, whereas none of these events was observed in the s-PRL group. Multivariate logistic analysis indicated that a history of lupus flares and serological activity (hypocomplementemia and/or anti-dsDNA positivity at the time of conception were associated with lupus flares in PRL mothers. CONCLUSIONS: SLE patients with a flare history and serological activity at the time of conception were at an increased risk of disease flares during pregnancy and puerperium. a-PRL patients were more prone to renal and hematological involvement, pregnancy complications, and a poorer prognosis despite more vigorous glucocorticoid treatment.

    Full Text Available Mette Mogensen1, Gregor BE Jemec21Department of Dermatology, Gentofte Hospital, Hellerup, Denmark; 2Department of Dermatology, Roskilde Hospital, Health Sciences Faculty, University of Copenhagen, Roskilde, DenmarkIntroduction: In 2009, the WHO listed ultraviolet (UV radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice.Methods: A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers.Results: Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior.Discussion: The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers.Keywords: tanning beds, skin cancers, melanoma, nonmelanoma

  5. Case Characterization, Clinical Features and Risk Factors in Drug-Induced Liver Injury

    Full Text Available Idiosyncratic drug-induced liver injury (DILI caused by xenobiotics (drugs, herbals and dietary supplements presents with a range of both phenotypes and severity, from acute hepatitis indistinguishable of viral hepatitis to autoimmune syndromes, steatosis or rare chronic vascular syndromes, and from asymptomatic liver test abnormalities to acute liver failure. DILI pathogenesis is complex, depending on the interaction of drug physicochemical properties and host factors. The awareness of risk factors for DILI is arising from the analysis of large databases of DILI cases included in Registries and Consortia networks around the world. These networks are also enabling in-depth phenotyping with the identification of predictors for severe outcome, including acute liver failure and mortality/liver transplantation. Genome wide association studies taking advantage of these large cohorts have identified several alleles from the major histocompatibility complex system indicating a fundamental role of the adaptive immune system in DILI pathogenesis. Correct case definition and characterization is crucial for appropriate phenotyping, which in turn will strengthen sample collection for genotypic and future biomarkers studies.

    1997-03-01

    Cranial MRI scans were performed in seventy-five infants determined to be at risk for neurological impairment in future. Thirty-four infants demonstrated a total of 51 lesions consistent with hypoxic ischemic encephalopathy (HIE), including periventricular leukomalacia with cysts (cystic PVL, n=4), PVL without cysts (linear PVL, n=15), intracerebral hemorrhage (ICH, n=7), intraventricular hemorrhage (IVH, n=4), and ventriculomegaly (n=21). Diagnoses by ultrasonography (US) were compared with those by MRI in all infants, respectively. US findings almost agreed with those of MRI except ventriculomegaly. PVL and IVH were seen most often in preterm infants, ICH occurred in full term infants. All infants of cystic PVL and 10 infants of linear PVL (67%) had developmental abnormalities. Thirty-nine infants had once or twice sequential MRI scans. In all infants with PVL, the findings of periventricular hyperintensity, volume loss of white matter and myelination delay were more evident at sequential MRI scans. These findings were correlated with the severity of developmental abnormalities. This study suggests that sequential MRI provides a more reliable prediction of neurological impairment. (author)

  7. Evaluating risks of acquired clinical vulnerability among subjects exposed to E-waste.

    Srivastava, Anup Kumar; Kesavachandran, Chandrasekharan Nair; Kumar, Sushil

    2011-01-01

    Acquired clinical vulnerability (ACV) results from insults that produce consequential pathophysiological changes and predispose exposed subjects to future disease. ACV comprises a complex biological process that is manifested by exposure to toxicants, generally over the course of many years, and results from subtle changes that occur at the cellular and molecular level. A large proportion of the world's population has already been, or will be, exposed to toxicants emanating from E-waste during the course of their lives. In countries where E-waste recycling is an important economic activity (China, India, among others), the challenge facing researchers is to devise suitable methods for identifying and objectively measuring ACV. Primary prevention can be achieved through legislation/awareness/monitoring and secondary prevention by developing innovative diagnostic tools and corrective measures. Studies in which attempts are made to define the health impact of multiple exposures, as routinely occurs in E-waste recycling, should include measures of as many of the following parameters as possible: (a) characterization of pollutant levels in air/water/soil at the residential or workplace, (b) periodical clinical examination of exposed subjects, (c) assessments of circulating toxicant loads in blood/urine/hair, (d) genomic variation and resultant susceptibility to complex biological responses, (viz, inflammation/dysplasia/immunosuppression/tissue regeneration) that derive from pathway modulation (viz., cytoskeleton/metabolism/cell adhesion/immune system/neuroactive ligand-receptor interaction/cytokine/signaling), (e) routine monitoring of altered gene expression from modulation of hematology or the above-mentioned pathways. E-waste exposure may also serve as a model for the types of multiple exposures that occur in other industrial or environmental exposures. Moreover, the approach used to study and address or alleviate E-waste exposure may also be useful in other

    2012-09-01

    Full Text Available Abstract Background To investigate a possible role of Cefditoren, a recently marketed in Greece third-generation oral cephalosporin in urinary infections of outpatients. Methods During a multicenter survey of Enterobacteriaceae causing UTIs in outpatients during 2005–2007, Cefditoren MICs were determined by agar dilution method in a randomly selected sample of uropathogens. Susceptibility against 18 other oral/parenteral antimicrobials was determined according to Clinical and Laboratory Standards Institute methodology. Results A total of 563 isolates (330 Escherichia coli, 142 Proteus mirabilis and 91 Klebsiella spp was studied; MIC50/MIC90 of Cefditoren was 0.25/0.5 mg/L respectively, with 97.1% of the isolates being inhibited at 1 mg/L. All 12 strains producing ESBLs or AmpC enzymes were resistant to cefditoren. Susceptibility rates (% for amoxicillin/clavulanic acid, cefuroxime axetil, cefotaxime, ciprofloxacin, trimethoprim/sulfamethoxazole and fosfomycin were 93.1- 94.1- 96.8-93.1-71.9 and 92.8% respectively. Cefditoren MIC was significantly higher in nalidixic/ciprofloxacin non-susceptible strains; resistance to cefditoren was not associated with resistance to mecillinam, fosfomycin nitrofurantoin and aminoglycosides. Multivariate analysis demonstrated history of urinary infection in the last two weeks or three months as risk factors for cefditoren resistance. Conclusions Cefditoren exhibited enhanced in vitro activity against the most common uropathogens in the outpatient setting, representing an alternative oral treatment option in patients with risk factors for resistance to first-line antibiotics.

    2016-01-01

    SUMMARY Background: The aim of this study is to describe clinical characteristics, outcomes and risk factors for death among patients with HIV-related acute kidney injury (AKI) admitted to an intensive care unit (ICU). Methods: A retrospective study was conducted with HIV-infected AKI patients admitted to the ICU of an infectious diseases hospital in Fortaleza, Brazil. All the patients with confirmed diagnosis of HIV and AKI admitted from January 2004 to December 2011 were included. A comparison between survivors and non-survivors was performed. Risk factors for death were investigated. Results: Among 256 AKI patients admitted to the ICU in the study period, 73 were identified as HIV-infected, with a predominance of male patients (83.6%), and the mean age was 41.2 ± 10.4 years. Non-survivor patients presented higher APACHE II scores (61.4 ± 19 vs. 38.6 ± 18, p = 0.004), used more vasoconstrictors (70.9 vs. 37.5%, p = 0.02) and needed more mechanical ventilation - MV (81.1 vs. 35.3%, p = 0.001). There were 55 deaths (75.3%), most of them (53.4%) due to septic shock. Independent risk factors for mortality were septic shock (OR = 14.2, 95% CI = 2.0-96.9, p = 0.007) and respiratory insufficiency with need of MV (OR = 27.6, 95% CI = 5.0-153.0, p < 0.001). Conclusion: Non-survivor HIV-infected patients with AKI admitted to the ICU presented higher severity APACHE II scores, more respiratory damage and hemodynamic impairment than survivors. Septic shock and respiratory insufficiency were independently associated to death. PMID:27410912

  10. Clinical diagnosis of metabolic and cardiovascular risks in overweight children: early development of chronic diseases in the obese child.

    l'Allemand-Jander, D

    2010-12-01

    Childhood overweight (body mass index (BMI)>90th centile) poses a major public health problem in so far as adult diseases manifest themselves already during childhood. In this review, after examining the prevalence of metabolic and cardiovascular diseases, the issue of whether BMI or other clinical parameters are valid tools to predict co-morbidities in children is discussed. Data of 2001-2008 are reviewed, including several studies conducted on more than 260,000 overweight and obese children in Germany and Switzerland. Apart from non-metabolic co-morbidities, namely musculoskeletal complications and attention deficit/hyperactivity disorders in up to 74% and up to 58% of overweight children, respectively, at least one cardiovascular and metabolic risk factor was seen in 52% of the overweight children, mostly high blood pressure (35%) with increased left ventricular mass or arterial stiffness. Signs of fatty liver disease or dyslipidemia were found in up to 29 and 32% of the children, respectively. Type 2 diabetes was found in less than 0.7% of the children, and an elevated fasting glucose or glucose intolerance in 3%. Irrespective of BMI, the quality of fat and protein intake predicted hypertension or insulin resistance, and fructose predicted lower (and more atherogenic) particle size of low-density lipoprotein-cholesterol. Out of the adiposity markers, waist circumference was closely correlated with insulin resistance and the components of the metabolic syndrome. In conclusion, risk factors are found in more than half of the overweight children, most frequently high blood pressure or dyslipidemia, and were mainly related to waist circumference, but also to BMI and fat mass. Even in the presence of normal BMI, screening for cardiovascular risk factors is advocated in each child with elevated waist circumference, but its cut-off points still remain to be validated. The increased occurrence of orthopedic and psychiatric complaints may detrimentally influence health

    Background Chagas disease (CD) is an important cause of heart failure and mortality, mainly in Latin America. This study evaluated the morphological and functional characteristics of the heart as well the extent of myocardial fibrosis (MF) in patients with CD by cardiac magnetic resonance (CMR). The prognostic value of MF evaluated by myocardial-delayed enhancement (MDE) was compared with that via Rassi score. Methods This study assessed 39 patients divided into 2 groups: 28 asymptomatic patients as indeterminate form group (IND); and symptomatic patients as Chagas Heart Disease (CHD) group. All patients underwent CMR using the techniques of cine-MRI and MDE, and the amount of MF was compared with the Rassi score. Results Regarding the morphological and functional analysis, significant differences were observed between both groups (p < 0.001). Furthermore, there was a strong correlation between the extent of MF and the Rassi score (r = 0.76). Conclusions CMR is an important technique for evaluating patients with CD, stressing morphological and functional differences in all clinical presentations. The strong correlation with the Rassi score and the extent of MF detected by CMR emphasizes its role in the prognostic stratification of patients with CD. PMID:27982271

    2004-09-01

    Full Text Available Abstract Background The epidemiology of obesity in primary care populations has not been thoroughly explored. This study contributes to filling this gap by investigating the relationship between obesity and different sources of personal stress, mental health, exercise, and demographic characteristics. Methods A cross-sectional survey using a convenience sample. Five hundred women who attended family planning clinics were surveyed and 274 provided completed answers to all of the questions analyzed in this study. Exercise, self-rated mental health, stress, social support, and demographic variables were included in the survey. Multiple logistic regression analysis was performed. Results After adjusting for mental health, exercise, and demographic characteristics of subjects, analysis of the data indicated that that being having a large family and receiving no support from parents were related to obesity in this relatively young low-income primary care sample, but self-reported stress and most types of social support were not significant. Conclusion Obesity control programs in primary care centers directed at low-income women should target women who have large families and who are not receiving support from their parents.

    Full Text Available Pierre MalliaMedical School, University of Malta, Mater Dei Hospital, MaltaAbstract: The ethical dimension of treating the elderly, including risk–benefit analysis, focuses mainly on quality of life and end-of-life issues. These include arguments on advance directives and the concept of extraordinary treatments. This paper looks more closely at the philosophical approach to aging in order to address questions on the direction of research and issues such as longevity and social construction of the aging process. It is the way society moves to understand the value-laden choices on aging that directs the goals of treatment and research. Whilst these vary culturally, one has to reckon with a postmodern view of aging which may, in turn, reflect on the course of action of future care and research in aging. The paper canvasses how, in reality, four principles act as guidelines for moral discourse, and discusses how changing values in society decide this course of action.Keywords: aging, principles, decision-making, conflict, treatment, clinical decision-making, social construction 

  14. Is there a role for coronary artery calcium scoring for management of asymptomatic patients at risk for coronary artery disease?: Clinical risk scores are not sufficient to define primary prevention treatment strategies among asymptomatic patients.

    Blaha, Michael J; Silverman, Michael G; Budoff, Matthew J

    2014-03-01

    Although risk factors have proven to be useful therapeutic targets, they are poor predictors of risk. Traditional risk scores are moderately successful in predicting future CHD events and can be a starting place for general risk categorization. However, there is substantial heterogeneity between traditional risk and actual atherosclerosis burden, with event rates predominantly driven by burden of atherosclerosis. Serum biomarkers have yet to show any clinically significant incremental value to the FRS and even when combined cannot match the predictive value of atherosclerosis imaging. As clinicians, are we willing to base therapy decisions on risk models that lack optimum-achievable accuracy and limit personalization? The decision to treat a patient in primary prevention must be a careful one because the benefit of therapy in an asymptomatic patient must clearly outweigh the potential risk. CAC, in particular, provides a personalized assessment of risk and may identify patients who will be expected to derive the most, and the least, net absolute benefit from treatment. Emerging evidence hints that CAC may also promote long-term adherence to aspirin, exercise, diet, and statin therapy. When potentially lifelong treatment decisions are on the line, clinicians must arm their patients with the most accurate risk prediction tools, and subclinical atherosclerosis testing with CAC is, at the present time, superior to any combination of risk factors and serum biomarkers.

    2014-09-01

    Full Text Available Introduction: Epilepsy is one of the most common neurological illnesses occurring in children. In approximately 20–30% of cases it is drug-resistant. Aim of the research: To assess the already-known risk factors, analyse the rarely described ones, and find new causes of epilepsy drug resistance in children, taking into account the level of impact of each factor. Material and methods : The study comprised 152 of all 383 children hospitalised in 2012 at the Neurology Department of the Polish Mother’s Memorial Hospital in Lodz due to epilepsy. Based on medical documentation, neurological examination, and our own questionnaire, we divided patients into two groups: drug-resistant epilepsy or drug-sensitive epilepsy. We compared the type, level of influence, and prevalence of different factors. For statistical analysis, the 2 test was used. Statistical significance was set at p < 0.05. Results: Drug-resistant epilepsy was found in 64 patients (42.1%, and drug-sensitive epilepsy was found in 88 patients (57.9%. Factors that were most probable to cause drug resistance included: high prevalence of seizures (Cramer’s V = 0.66, type of epileptic syndrome (V = 0.62, psychomotor developmental delay (V = 0.62, and occurrence of status epilepticus (V = 0.6. Factors such as infections of CNS in early childhood, repeated severe infections of airways in childhood, and mother’s infectious diseases with high fever during pregnancy were rare or non occurring (Cramer’s V = 0.41, 0.32, and 0.31, respectively. Conclusions : The study confirmed the previously known causes of drug resistance and indicated the significance of underestimated inflammatory and infectious factors involving pyrexia, in children and also in mothers during pregnancy.

    2016-01-01

    Full Text Available Background: Patients with schizophrenia (SZ are generally overweight or obese and have several metabolic disorders. Additionally, such patients have a lower life expectancy and the main cause of their increased mortality is cardiovascular disease (CVD. The objective of this study was to determine the efficacy of resveratrol supplementation on serum glucose and CVD risk factors in individuals with SZ. Methods and Results: This is a four-week randomized, double-blind controlled trial (registration No.: NCT 02062190 in which 19 men with a diagnosis of SZ, aged 18 to 65, were assigned to either a resveratrol supplement group (200 mg/day or a placebo group (200 mg/day. In short, we did not observe significant changes after resveratrol supplementation. In the placebo group, we found a significant increase in total cholesterol levels (p = 0.024 and in LDL-cholesterol (p = 0.002, as well as a decrease in body fat percentage (p = 0.038. The placebo group also showed an increase in triglycerides (9.19% and a reduction in HDL-cholesterol (4.88%. In the resveratrol group, triglycerides decreased (7.64%. Conclusion: In summary, oral resveratrol in reasonably low dosages (200 mg daily brought no differences to body weight, waist circumference, glucose, and total cholesterol. It was possible to note that the lipid profile in the placebo group worsened and, although no significant differences were found, we can assume that resveratrol might prevent lipid profile damage and that the intervention affected the lipoprotein metabolism at various levels.

    Mahendra Narain Mishra

    Full Text Available CONTEXT AND OBJECTIVE: Arterial thrombosis may occur consequent to hereditary thrombophilia and increased lipoprotein(a [Lp(a] and fibrinogen. Our aim was to study the prevalence of common thrombophilia markers in 85 consecutive cases of arterial thrombosis. DESIGN AND SETTING: A retrospective study was conducted from 85 consecutive young patients treated as outpatients or admitted due to stroke or myocardial infarction at a tertiary care hospital. METHODS: Eighty-five Indian patients (age < 45 years presenting ischemic stroke (n = 48 or myocardial infarction (n = 37 and 50 controls were studied for seven thrombophilia markers including antithrombin (AT, factor V, protein C, protein S, activated protein C resistance (APC-R, fibrinogen and Lp(a. Functional assays for protein C, protein S, factor V and APC-R were performed using clotting-based methods. Semi-quantitative estimation of fibrinogen was done using Clauss's method and Lp(a using immunoturbidimetry. Statistical analysis was done using the Epi Info 6 software. RESULTS: Thirty-three samples (38.8% tested positive for one or more thrombophilia markers. The three commonest abnormalities were elevated Lp(a (20%, fibrinogen (17.6% and low APC-R (14.2%. Low levels of protein C, protein S and AT were present in 4.7, 9.4 and 7% of the patients, respectively. Overall, the risk factor profile was: smoking (33%, positive family history (15.3%, hyperlipidemia (7%, hypertension, diabetes mellitus and obesity (2.3% each. CONCLUSIONS: An association was found between low levels of protein C, protein S and AT and arterial thrombosis, but only elevated fibrinogen levels, smoking, positive family history and hyperlipidemia showed statistical significance.

    Background. Aspirin use for cardiovascular or cancer prevention is limited due to its gastrointestinal side effects. Objective. Our prospective, observational case-control study aims to identify the predictive factors for ulcers in low-dose aspirin consumers (75-325 mg/day). Methods. The study included patients who underwent an upper digestive endoscopy and took low-dose aspirin treatment. Results. We recruited 51 patients with ulcer (ulcer group) and 108 patients with no mucosal lesions (control group). In univariate analysis, factors significantly associated with ulcers were male gender (p = 0.001), anticoagulants (p = 0.029), nonsteroidal anti-inflammatory drugs (p = 0.013), heart failure (p = 0.007), liver (p = 0.011) or cerebrovascular disease (p = 0.004), diabetes mellitus (p = 0.043), ulcer history (p = 0.044), and alcohol consumption (p = 0.018), but not Helicobacter pylori infection (p = 0.2). According to our multivariate regression analysis results, history of peptic ulcer (OR 3.07, 95% CI 1.06-8.86), cotreatment with NSAIDs (OR 8, 95% CI 2.09-30.58) or anticoagulants (OR 4.85, 95% CI 1.33-17.68), male gender (OR 5.2, 95% CI 1.77-15.34), and stroke (OR 7.27, 95% CI 1.40-37.74) remained predictors for ulcer on endoscopy. Conclusions. Concomitant use of NSAIDs or anticoagulants, comorbidities (cerebrovascular disease), and male gender are the most important independent risk factors for ulcer on endoscopy in low-dose aspirin consumers, in a population with a high prevalence of H. pylori infection.

    The CHA2DS2-VASc score is a 10-point scale which allows cardiologists to easily identify potential stroke risk for patients with non-valvular fibrillation. In this article, we present a system based on natural language processing (lexicon and linguistic modules), including negation and speculation handling, which extracts medical concepts from French clinical records and uses them as criteria to compute the CHA2DS2-VASc score. We evaluate this system by comparing its computed criteria with those obtained by human reading of the same clinical texts, and by assessing the impact of the observed differences on the resulting CHA2DS2-VASc scores. Given 21 patient records, 168 instances of criteria were computed, with an accuracy of 97.6%, and the accuracy of the 21 CHA2DS2-VASc scores was 85.7%. All differences in scores trigger the same alert, which means that system performance on this test set yields similar results to human reading of the texts.

  1. Bacillary Angiomatosis in an HIV-positive Man with Multiple Risk Factors: A Clinical and Epidemiological Puzzle

    2005-01-01

    Full Text Available A 36-year-old man with advanced AIDS presented with skin lesions, fever and weight loss. Physical examination revealed skin lesions suggestive of bacillary angiomatosis. Diagnostic imaging identified bone lesions, soft tissue masses and a single hepatic lesion. His clinical presentation was most consistent with Bartonella quintana; however, his risk for infection with B quintana was limited to a remote, brief period of homelessness. In contrast, his frequent contact with cats presented substantial potential exposure to Bartonella henselae. Diagnosing a Bartonella infection presents challenges. The detection of bacteremia is hindered by slow growth in BACTEC media (BD Diagnostic Systems, Canada. In the present case, recovery of the organism required blind subcultures after at least eight days of incubation. Speciation by 16s ribosomal RNA analysis confirmed B quintana as the pathogen. Because the patient presented with skin lesions, the diagnosis was straightforward; however, skin lesions are nondiagnostic in some cases. Microbiological confirmation of the diagnosis rests on sufficient clinical suspicion to apply labour-intensive laboratory protocols.

    Introduction: Level I evidence supports the use of cisplatin-based neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer prior to radical cystectomy (RC). On average, 30–40% of patients achieve a complete pathologic response (i.e., stage pT0) after receiving NAC. Some centers risk-stratify patients, suggesting that there may be a higher-risk population that would derive the most benefit from NAC. Recently, a risk-stratification model developed at M.D. Anderson Cancer Center (MDACC) specified criteria for clinical staging and patient selection for NAC. We applied this model to our own RC patient cohort and evaluated our own experience with clinical risk stratification and the effect of NAC on post treatment risk categories. Methods: We retrospectively reviewed the charts of consecutive patients who underwent RC at two institutions between 2004 and 2014 and noted whether or not they received NAC. We determined the clinical stage by reviewing the exam under anesthesia, transurethral resection biopsy (TURBT) pathology, and preoperative imaging. Patients with cT2-T4a node-negative disease were included. Those with sarcomatoid features or adenocarcinoma were excluded. Patients were classified as high risk if they had tumor-associated hydronephrosis, clinical stage≥T3b-T4a disease, variant histology (i.e., micropapillary or small cell), or lymphovascular invasion (LVI), as specified by the MDACC model. Variables were examined for associations with cancer-specific survival (CSS), overall survival (OS), and risk-category reclassification. Results: We identified 166 patients with a median follow-up time of 22.2 months. In all, 117 patients (70.5%) did not receive NAC, 68 (58.1%) of whom we classified as high risk. Among patients not receiving NAC, CSS and OS were significantly decreased in high-risk patients (log-rank test p = 0.01 for both comparisons). The estimated age-adjusted hazard ratios of high-risk classification for cancer-specific and overall

    Full Text Available Abstract Background Avahan, the India AIDS Initiative, implemented a large HIV prevention programme across six high HIV prevalence states amongst high risk groups consisting of female sex workers, high risk men who have sex with men, transgenders and injecting drug users in India. Utilization of the clinical services, health seeking behaviour and trends in syndromic diagnosis of sexually transmitted infections amongst these populations were measured using the individual tracking data. Methods The Avahan clinical monitoring system included individual tracking data pertaining to clinical services amongst high risk groups. All clinic visits were recorded in the routine clinical monitoring system using unique identification numbers at the NGO-level. Visits by individual clinic attendees were tracked from January 2005 to December 2009. An analysis examining the limited variables over time, stratified by risk group, was performed. Results A total of 431,434 individuals including 331,533 female sex workers, 10,280 injecting drug users, 82,293 men who have sex with men, and 7,328 transgenders visited the clinics with a total of 2,700,192 visits. Individuals made an average of 6.2 visits to the clinics during the study period. The number of visits per person increased annually from 1.2 in 2005 to 8.3 in 2009. The proportion of attendees visiting clinics more than four times a year increased from 4% in 2005 to 26% in 2009 (p Conclusions The programme demonstrated that acceptable and accessible services with marginalised and often difficult–to-reach populations can be brought to a very large scale using standardized approaches. Utilization of these services can dramatically improve health seeking behaviour and reduce STI prevalence.

    Full Text Available Abstract Background Sub-clinical mastitis limits milk production and represents an important barrier to profitable livestock economics worldwide. Milk production from cows in Nigeria is not at optimum levels in view of many factors including sub-clinical mastitis. Results The overall herd-level prevalence rate for SCM was 85.33% (256/300 heads of cows while the quarter-level prevalence rate of SCM was 43.25% (519/1,200 quarters. The prevalence of SCM was 50.67%, 43.67%, 39.67% and 39.13% for the left fore-quarter, right hind-quarter, left hind-quarter and right fore-quarter, respectively. The Rahaji breed had the highest prevalence of SCM with 65.91% (29/44, while the White Fulani breed had the least with 32.39% (57/176. A total of 32.33% (97/300 had only one mammary quarter affected, 30.33% (91/300 had two quarters affected, 16.00% (48/300 had three quarters affected while 6.67% (20/300 had all the four quarters affected. A total of 53.00% had SCM in multiple quarters (159/300. The risk of SCM decreased significantly among young lactating cows compared to older animals (OR = 0.283; P P = 0.013; 95% CI = 1.557; 43.226. Improved sanitation (washing hands before milking will decrease the risk of SCM (OR = 0.173; P = 0.003; 95% CI = 0.054; 0.554. Conclusion SCM is prevalent among lactating cows in the Nigerian Savannah; and this is associated with both animal characteristics (age, breed and individual milk quarters and milking practices (hand washing.Good knowledge of the environment and careful management of the identified risk factors with improved sanitation should assist farm managers and veterinarians in implementing preventative programmes to reduce the incidence of SCM.

    Currently, English scientific literature is lacking in studies showing that medical assistance may be delivered without errors. Since two years ago, the department of nephrology and urology of ASL BA has been establishing a process of clinical risk management.Starting with the reporting of a single error, a related database was subsequently developed, in order to validate technical and organizational procedures that would be of common use in the daily clinical practice.With regard to error reporting, the system of incident reporting was adopted: that is a structured collection of significant events for the safety of patients with a specific form for reporting to be filled out by health professionals. Reports have been collected, coded and analysed. Finally measures were adopted to reduce the recurrence of the error.This first phase consisted on writing the procedures in order to create structured diagnostic-therapeutic protocols. In 18 months of observation adopting the incident reporting form, 48 errors have been reported: 52% due to adverse events; 12.5% to adverse reactions; 31.2% near misses and 2% to sentinel events. In 35.4 % of cases the error occurred in the administration or prescription of drug therapies, in 18.7% of cases it occurred in the organizational stage, in 12.5% it was a surgical error, in 18.7% of cases the error was due to incorrect asepsis, in 8.3% of cases it occurred during the medical examination and finally in 8.3% during dialysis. An analysis of the error database resulted in the choice of more urgent procedures. It is our view that only the observation of procedures can ensure the achievement of a high quality with improved clinical outcomes, reduction of complications, elimination of inappropriate interventions and increased patient satisfaction.

    2014-01-01

    Background The pathogenesis of benign prostatic hyperplasia (BPH) has been widely studied,and several biomarkers are known to play roles in its development.This study aimed to investigate the possible role of cysteine-rich protein 61 (CYR61),vascular endothelial growth factor (VEGF),androgen receptor (AR),interleukin-6 (IL-6),cytochrome c,caspase-3,and proliferating cell nuclear antigen (PCNA) in the clinical progression of BPH.Methods Tissue specimens from 96 BPH cases who underwent transurethral resection of the prostate were processed and transferred to tissue microarrays.Patient age,prostate volume,serum prostate-specific antigen (PSA) level,and International Prostate Symptom Score (IPSS) of all BPH cases were collected before surgery.The expression of CYR61,VEGF,AR,IL-6,cytochrome c,caspase-3,and PCNA was examined by immunostaining in the BPH specimens,and any possible correlation between the different biomarkers and risk factors for BPH clinical progression was analyzed.Results The expression of CYR61,VEGF,AR,IL-6,cytochrome c,caspase-3,and PCNA in the BPH cases was 68.8% (66/96),77.1% (74/96),43.8% (42/96),31.3% (30/96),35.4% (34/96),56.3% (54/96),and 29.2% (28/96),respectively.The expression of both CYR61 and VEGF was positively correlated with patient age,prostate volume,and serum PSA level (P <0.05).Furthermore,cytochrome c and caspase-3 expression were inversely related to prostate volume (P <0.05),and AR expression was positively related to serum PSA level (P <0.05).Conclusion CYR61 and VEGF expression might serve as biomarkers for predicting the clinical progression of BPH due to effects on stromal cell proliferation and angiogenesis.

    The aims of this study were to estimate the incidence rate of clinical mastitis (IRCM) and identify risk factors for clinical mastitis in suckler ewes to generate hypotheses for future study. A postal questionnaire was sent to 999 randomly selected English sheep farmers in 2010 to gather data on farmer reported IRCM and flock management practices for the calendar year 2009, of which 329 provided usable information. The mean IRCM per flock was 1.2/100 ewes/year (CI:1.10:1.35). The IRCM was 2.0, 0.9 and 1.3/100 ewes/year for flocks that lambed indoors, outdoors and a combination of both, respectively. Farmers ran a variety of managements before, during and after lambing that were not comparable within one model, therefore six mixed effects over-dispersed Poisson regression models were developed. Factors significantly associated with increased IRCM were increasing percentage of the flock with poor udder conformation, increasing mean number of lambs reared/ewe and when some or all ewes lambed in barns compared with outdoors (Model 1). For ewes housed in barns before lambing (Model 2), concrete, earth and other materials were associated with an increase in IRCM compared with hardcore floors (an aggregate of broken bricks and stones). For ewes in barns during lambing (Model 3), an increase in IRCM was associated with concrete compared with hardcore flooring and where bedding was stored covered outdoors or in a building compared with bedding stored outdoors uncovered. For ewes in barns after lambing (Model 4), increased IRCM was associated with earth compared with hardcore floors, and when fresh bedding was added once per week compared with at a frequency of ≤2 days or twice/week. The IRCM was lower for flocks where some or all ewes remained in the same fields before, during and after lambing compared with flocks that did not (Model 5). Where ewes and lambs were turned outdoors after lambing (Model 6), the IRCM increased as the age of the oldest lambs at turnout

  9. Precedent fluctuation of serum hs-CRP to albumin ratios and mortality risk of clinically stable hemodialysis patients.

    Jyh-Chang Hwang

    Full Text Available A high sensitivity C-reactive protein to albumin ratio (hs-CRP/Alb predicts mortality risk in patients with acute kidney injury. However, it varies dynamically. This study was conducted to evaluate whether a variation of this marker was associated with long-term outcome in clinically stable hemodialysis (HD patients.hs-CRP/Alb was checked bimonthly in 284 clinically stable HD outpatients throughout all of 2008. Based on the "slope" of trend equation derived from 5-6 hs-CRP/alb ratios for each patient, the total number of patients was divided into quartiles--Group 1: β≦ -0.13, n = 71; group 2: β>-0.13≦0.003; n = 71, group 3: β>0.003≦0.20; and group 4: β>0.20, n = 71. The observation period was from January 1, 2009 to August 31, 2012.Group 1+4 showed a worse long-term survival (p = 0.04 and a longer 5-year hospitalization stay than Group 2+3 (38.7±44.4 vs. 16.7±22.4 days, p<0.001. Group 1+4 were associated with older age (OR = 1.03, 95% CI = 1.01-1.05 and a high prevalence of congestive heart failure (OR = 2.02, 95% CI = 1.00-4.11. Standard deviation (SD of hs-CRP/Alb was associated with male sex (β = 0.17, p = 0.003, higher Davies co-morbidity score (β = 0.16, p = 0.03, and baseline hs-CRP (β = 0.39, p<0.001. Patients with lower baseline and stable trend of hs-CRP/Alb had a better prognosis. By multivariate Cox proportional methods, SD of hs-CRP/alb (HR: 1.05, 95% CI: 1.01-1.08 rather than baseline hs-CRP/Alb was an independent predictive factor for long-term mortality after adjusting for sex and HD vintage.Clinically stable HD patients with a fluctuating variation of hs-CRP/Alb are characterized by old age, and more co-morbidity, and they tend to have longer subsequent hospitalization stay and higher mortality risk.

    Purpose: Irradiation of pediatric facial structures can cause severe impairment of permanent teeth later in life. We therefore focused on primary and permanent teeth as organs at risk, investigating the ability to identify individual teeth in children and infants and to correlate dose distributions with subsequent dental toxicity. Methods and Materials: We retrospectively reviewed 14 pediatric patients who received a maximum dose >20 Gy(relative biological effectiveness, RBE) to 1 or more primary or permanent teeth between 2003 and 2009. The patients (aged 1-16 years) received spot-scanning proton therapy with 46 to 66 Gy(RBE) in 23 to 33 daily fractions for a variety of tumors, including rhabdomyosarcoma (n=10), sarcoma (n=2), teratoma (n=1), and carcinoma (n=1). Individual teeth were contoured on axial slices from planning computed tomography (CT) scans. Dose-volume histogram data were retrospectively obtained from total calculated delivered treatments. Dental follow-up information was obtained from external care providers. Results: All primary teeth and permanent incisors, canines, premolars, and first and second molars were identifiable on CT scans in all patients as early as 1 year of age. Dose-volume histogram analysis showed wide dose variability, with a median 37 Gy(RBE) per tooth dose range across all individuals, and a median 50 Gy(RBE) intraindividual dose range across all teeth. Dental follow-up revealed absence of significant toxicity in 7 of 10 patients but severe localized toxicity in teeth receiving >20 Gy(RBE) among 3 patients who were all treated at <4 years of age. Conclusions: CT-based assessment of dose distribution to individual teeth is feasible, although delayed calcification may complicate tooth identification in the youngest patients. Patterns of dental dose exposure vary markedly within and among patients, corresponding to rapid dose falloff with protons. Severe localized dental toxicity was observed in a few patients receiving the

    Bartsch, Emily; Medcalf, Karyn E; Park, Alison L

    2016-01-01

    Objective To develop a practical evidence based list of clinical risk factors that can be assessed by a clinician at ≤16 weeks’ gestation to estimate a woman’s risk of pre-eclampsia. Design Systematic review and meta-analysis of cohort studies. Data sources PubMed and Embase databases, 2000-15. Eligibility criteria for selecting studies Cohort studies with ≥1000 participants that evaluated the risk of pre-eclampsia in relation to a common and generally accepted clinical risk factor assessed at ≤16 weeks’ gestation. Data extraction Two independent reviewers extracted data from included studies. A pooled event rate and pooled relative risk for pre-eclampsia were calculated for each of 14 risk factors. Results There were 25 356 688 pregnancies among 92 studies. The pooled relative risk for each risk factor significantly exceeded 1.0, except for prior intrauterine growth restriction. Women with antiphospholipid antibody syndrome had the highest pooled rate of pre-eclampsia (17.3%, 95% confidence interval 6.8% to 31.4%). Those with prior pre-eclampsia had the greatest pooled relative risk (8.4, 7.1 to 9.9). Chronic hypertension ranked second, both in terms of its pooled rate (16.0%, 12.6% to 19.7%) and pooled relative risk (5.1, 4.0 to 6.5) of pre-eclampsia. Pregestational diabetes (pooled rate 11.0%, 8.4% to 13.8%; pooled relative risk 3.7, 3.1 to 4.3), prepregnancy body mass index (BMI) >30 (7.1%, 6.1% to 8.2%; 2.8, 2.6 to 3.1), and use of assisted reproductive technology (6.2%, 4.7% to 7.9%; 1.8, 1.6 to 2.1) were other prominent risk factors. Conclusions There are several practical clinical risk factors that, either alone or in combination, might identify women in early pregnancy who are at “high risk” of pre-eclampsia. These data can inform the generation of a clinical prediction model for pre-eclampsia and the use of aspirin prophylaxis in pregnancy. PMID:27094586

    Background Acute kidney injury (AKI) has been recognized as a major healthcare problem affecting millions of patients worldwide.However,epidemiologic data concerning AKI in China are still lacking.The objectives of this study were to characterize AKI defined by RIFLE criteria,assess the association with hospital mortality,and evaluate the impact of AKI in the context of other risk factors.Methods This prospective multicenter observational study enrolled 3,063 consecutive patients from 1 July 2009 to 31 August 2009 in 22 ICUs across mainland China.We excluded patients who were admitted for less than 24 hours (n=1623),younger than 18 years (n=127),receiving chronic hemodialysis (n=29),receiving renal transplantation (n=1) and unknown reasons (n=28).There were 1255 patients in the final analysis.AKI was diagnosed and classified according to RIFLE criteria.Results There were 396 patients (31.6%) who had AKI,with RIFLE maximum class R,I,and F in 126 (10.0%),91 (7.3%),and 179 (14.3%) patients,respectively.Renal function deteriorated in 206 patients (16.4%).In comparison with non AKI patients,patients in the risk class on ICU admission were more likely to progress to the injury class (odds ratio (OR) 3.564,95% confidence interval (CI) 1.706-7.443,P =0.001],while patients in the risk class (OR 5.215,95% CI 2.798-9.719,P <0.001) and injury class (OR 13.316,95% CI 7.507-23.622,P <0.001) had a significantly higher probability of deteriorating into failure class.The adjusted hazard ratios for 90-day mortality were 1.884 for the risk group,3.401 for the injury group,and 5.306 for the failure group.Conclusions The prevalence of AKI was high among critically ill patients in Chinese ICUs.In comparison with non-AKI patients,patients with RIFLE class R or class I on ICU admission were more susceptibility to progression to class I or class F.The RIFLE criteria were robust and correlated well with clinical deterioration and mortality.

  16. Clinical governance and research ethics as barriers to UK low-risk population-based health research?

    Douglas Flora

    2008-11-01

    Full Text Available Abstract Background Since the Helsinki Declaration was introduced in 1964 as a code of practice for clinical research, it has generally been agreed that research governance is also needed in the field of public health and health promotion research. Recently, a range of factors led to the development of more stringent bureaucratic procedures, governing the conduct of low-risk population-based health research in the United Kingdom. Methods Our paper highlights a case study of the application process to medical research ethics committees in the United Kingdom for a study of the promotion of physical activity by health care providers. The case study presented here is an illustration of the challenges in conducting low-risk population-based health research. Results Our mixed-methods approach involved a questionnaire survey of and semi-structured interviews with health professionals (who were all healthy volunteers. Since our study does not involve the participation of either patients or the general population, one would expect the application to the relevant research ethics committees to be a formality. This proved not to be the case! Conclusion Research ethics committees could be counter-productive, rather than protecting the vulnerable in the research process, they can stifle low-risk population-based health research. Research ethics in health services research is first and foremost the responsibility of the researcher(s, and we need to learn to trust health service researchers again. The burden of current research governance regulation to address the perceived ethical problems is neither appropriate nor adequate. Senior researchers/academics need to educate and train students and junior researchers in the area of research ethics, whilst at the same time reducing pressures on them that lead to unethical research, such as commercial funding, inappropriate government interference and the pressure to publish. We propose that non-invasive low-risk

Cette étude avait pour objectif d’évaluer les modifications du poids et des facteurs de risque cardiovasculaire chez les participantes, après six mois de consultations à la clinique. Méthodes : Nous avons mené une analyse rétrospective des dossiers des femmes dont la grossesse avait été compliquée par la prééclampsie et qui avaient par la suite fréquenté la Postpartum Preeclampsia Clinic. Pour déterminer les paramètres de départ, les participantes à l’étude ont été soumises à des évaluations du mode de vie, à des examens physiques et à des analyses de laboratoire. Des objectifs personnalisés en matière de réduction du risque cardiovasculaire et de modification du mode de vie ont été établis, le tout étant axé sur l’activité physique et les modifications du régime alimentaire. La modification du poids constituait le critère d’évaluation principal. Résultats : Au cours de la période d’étude, 21 femmes ont fait l’objet d’un suivi d’une durée minimale de six mois. À 4,4 ± 1,4 mois postpartum en moyenne (± σ), les participantes présentaient une amélioration non significative en matière de poids (perte pondérale moyenne de 0,4 ± 4,5 kg) et d’IMC (diminution moyenne de l’IMC de 0,1 ± 1,7 kg/m2). Le niveau d’activité physique a connu une amélioration significative, passant de 14 % des participantes pratiquant des activités physiques avant la grossesse à 76 % après 4,4 mois postpartum en moyenne

    Background: Few data exist regarding cardiovascular risk among HIV-infected patients attending sexual health clinics (SHC) in Australia. Methods: The medical records of 188 patients attending an inner-city SHC between August 2013 and July 2014 were retrospectively reviewed for cardiovascular risk factors and associated screening and management practices. Results: Cardiovascular risk factors were common among attendees of the SHC, including smoking (38%), hypertension (14%) and dyslipidaemia (11%). Of the 188 patients, 23% reported using potentially cardiotoxic recreational drugs, 25% of dyslipidaemic patients were not on therapy and 10% of patients were hypertensive; none were prescribed treatment. A smoking cessation program was offered to all patients. Conclusion: A high prevalence of risk factors for cardiovascular disease was demonstrated. Modification of risk factors could be improved.

    Personal and family health histories remain important independent risk factors for cancer; however they are currently not being well collected or used effectively. Health Heritage was designed to address this need. The purpose of this study was to validate the ability of Health Heritage to identify patients appropriate for further genetic evaluation and to accurately stratify cancer risk. A retrospective chart review was conducted on 100 random patients seen at an adult genetics clinic presenting with concern for an inherited predisposition to cancer. Relevant personal and family history obtained from the patients' medical records was entered into Health Heritage. Recommendations by Health Heritage were compared to national guidelines of eligibility for genetic evaluation. Agreement between Health Heritage referral for genetic evaluation and guideline eligibility for genetic evaluation was 97% (sensitivity 98% and specificity 88%). Risk stratification for cancer was also compared between Health Heritage and those documented by a geneticist. For patients at increased risk for breast, ovarian, or colorectal cancer as determined by the geneticist, risk stratification by Health Heritage agreed 90, 93, and 75%, respectively. Discordances in risk stratification were attributed to both complex situations better handled by the geneticist and Health Heritage's adherence to incorporating all information into its algorithms. Health Heritage is a clinically valid tool to identify patients appropriate for further genetic evaluation and to encourage them to confirm the assessment and management recommendations with cancer genetic experts. Health Heritage also provides an estimate of cancer risk that is complementary to a genetics team.

    Full Text Available Clinical course, prognosis and mechanisms of separate forms of heart rhythm disorders in children differ from those in adults. Especially, it refers to new-borns and infants whose conduction system differs by functional and morphologic immaturity. In connection with it, the assessment of natural history of heart rhythm disorders, occurred in a perinatal period, and determination of risk factors of arrhythmia appearance in infants are of some interest. 88 newborns took part in the study. The patients were involved by continuous sampling technique. Risk factors, occurred in a perinatal period and potentially influenced on development of heart rhythm disorders, were assessed. In our study we took biological, gynecologic and obstetric history, data of gestation and delivery course, early and late neonatal period, early infancy, Echo, neurosonography, Holter monitoring with determination of heart rhythm variability, and determined thyroid hormonal status. Maximum specific gravity had extrasystoles – 32.4% – in the structure of idiopathic arrhythmias in infants. Heart rhythm disorders with natural history were kept at six months of life only in 5,4% of children. Persistence of arrhythmias was marked during one year only for WPW syndrome. Heart rhythm disorders are often marked significantly in children whose mothers had acute respiratory disease during the pregnancy, or if the children were born from the first pregnancy, had the signs of central nervous system damage syndromes in an early perinatal period (arrest, intracranial hypertension, convulsive disorder. Disorders of autonomic imbalance of cardiac function and peculiarities of hemodynamics of pulmonary circulation contribute significantly into appearance and persistence of all types of arrhythmias. On the whole, the prognosis of heart rhythm disorders, occurred in the perinatal period, without organic and structural changes of myocardium is favorable. The exclusion can be made for

    Rossana Berardi

    Full Text Available Hyponatraemia has been reported with targeted therapies in cancer patients. Aim of the study was to perform an up-to-date meta-analysis in order to determine the incidence and relative risk (RR in cancer patients treated with these agents.The scientific literature regarding hyponatraemia was extensively reviewed using MEDLINE, PubMed, Embase and Cochrane databases. Eligible studies were selected according to PRISMA statement. Summary incidence, RR, and 95% Confidence Intervals were calculated using random-effects or fixed-effects models based on the heterogeneity of selected studies.4803 potentially relevant trials were identified: of them, 13 randomized phase III studies were included in this meta-analysis. 6670 patients treated with 8 targeted agents were included: 2574 patients had hepatocellular carcinoma, whilst 4096 had other malignancies. The highest incidences of all-grade hyponatraemia were observed with the combination of brivanib and cetuximab (63.4 and pazopanib (31.7, while the lowest incidence was reported by afatinib (1.7. The highest incidence of high-grade hyponatraemia was reported by cetuximab (34.8, while the lowest incidences were reported by gefitinib (1.0. Summary RR of developing all-grade and high-grade hyponatraemia with targeted agents was 1.36 and 1.52, respectively. The highest RRs of all-grade and high-grade hyponatraemia were associated with brivanib (6.5 and 5.2, respectively. Grouping by drug category, the RR of high-grade hyponatraemia with angiogenesis inhibitors was 2.69 compared to anti-Epidermal Growth Factor Receptors agents (1.12.Treatment with biological therapy in cancer patients is associated with a significant increased risk of hyponatraemia, therefore frequent clinical monitoring should be emphasized when managing targeted agents.

    The prevalence of the heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) phenotype among methicillin-resistant S. aureus (MRSA) blood isolates can reach 38%. hVISA bacteremia is known to be associated with vancomycin treatment failure, including persistent bacteremia. We conducted this study to evaluate risk factors for 12-week mortality in patients with hVISA bacteremia through a detailed clinical and microbiological analysis of a prospective cohort of patients with S. aureus bacteremia. All isolates were collected on the first day of bacteremia and subjected to population analysis profiling for hVISA detection, genotyping, and PCR analysis for 39 virulence factors. Of 382 patient with MRSA bacteremia, 121 (32%) had hVISA bacteremia. Deceased patients were more likely to have hematologic malignancy (P = 0.033), ultimately or rapidly fatal disease (P = 0.007), and a higher Pitt bacteremia score (P = 0.010) than surviving patients. The sequence type 239 (ST239) clonal type and definitive linezolid treatment were associated with a trend toward reduced mortality (P = 0.061 and 0.072, respectively), but a high vancomycin MIC (≥2 mg/liter) was not associated with increased mortality (P = 0.368). In a multivariate analysis, ultimately or rapidly fatal disease (adjusted odds ratio [aOR], 2.80; 95% confidence interval [CI], 1.14 to 6.85) and a high Pitt bacteremia score (aOR, 1.26; 95% CI, 1.07 to 1.48) were independent risk factors for mortality. Hematologic malignancy was associated with a trend toward increased mortality (P = 0.094), and ST239 was associated with a trend toward reduced mortality (P = 0.095). Our study suggests that ST239 hVISA is a possible predictor of survival in hVISA bacteremia. PMID:25845875

    The purpose of this study is to investigate the risk factors and susceptibilities to antifungal agents of Candida albicans and Candida non-albicans species (spp.) in candidemia cases in Kobe University Hospital. We investigated all consecutive patients with candida bloodstream infection (BSI) from 2008-2013 for whose full data were available for analyses, examining clinical factors such as gender, general complications, postoperative status or susceptibilities to antifungal agents. These factors were also compared between Candida albicans spp. and Candida non-albicans by univariate and multivariate analyses. Univariate analyses showed a significantly higher rate of Candida non-albicans species BSI patients cancer (odds ratio (OR) (95% confidence interval (CI))=2.29 (1.04-5.06) and P=0.040), chemotherapy (OR=4.35 (1.11-17.1) and P=0.035), fluconazole (FLCZ) resistance (OR=77.3 (4.51-1324) and P=0.003), and itraconazole (ITCZ) resistance (OR=15.6 (5.39-45.1) and PCandida albicans. Multivariate analyses demonstrated that Candida non-albicans spp. had significantly higher rate of chemotherapy (OR=4.44 (1.04-19.0) and P=0.045), FLCZ resistance (OR=5.87 (2.01-17.1) and P=0.001), and ITCZ resistance (OR=18.7(5.77-60.4) and PCandida albicans. In conclusion, this study revealed several risk factors for BSI with Candida albicans (underlying cardiovascular diseases and postoperative status) and Candida non-albicans spp. (cancer and chemotherapy), and demonstrated that Candida non-albicans spp. were more resistant to FLCZ and ITCZ than Candida albicans.

    Purpose: To map the location of metastatic supraclavicular (SCV) lymph nodes (LNMs) in breast cancer patients with SCV node involvement and determine whether and where the radiation therapy clinical target volume (CTV) of this region could be modified in high-risk subsets. Methods and Materials: Fifty-five patients with metastatic SCV LNMs were eligible for geographic mapping and atlas coverage analysis. All LNMs and their epicenters were registered proportionally by referencing the surrounding landmarks onto simulation computed tomography images of a standard patient. CTVs based on selected SCV atlases, including the one by the Radiation Therapy Oncology Group (RTOG) were contoured. A modified SCV CTV was tried and shown to have better involved-node coverage and thus theoretically improved prophylaxis in this setting. Results: A total of 50 (91%) and 45 (81.8%) patients had LNMs in the medial and lateral SCV subregions, respectively. Also, 36 patients (65.5%) had LNMs located at the junction of the jugular-subclavian veins. All nodes were covered in only 25.5% to 41.8% of patients by different atlases. The RTOG atlas covered all nodes in 25.5% of patients. Stratified by the nodes in all the patients as a whole, 49.2% to 81.3% were covered, and the RTOG atlas covered 62.6%. The lateral and posterior borders were the most overlooked locations. Modification by extending the borders to natural anatomic barriers allowed the new CTV to cover all the nodes in 81.8% of patients and encompass 96.1% of all the nodes. Conclusions: According to the distribution of SCV LNMs, the extent of existing atlases might not be adequate for potential metastatic sites in certain groups of patients. The extension of the lateral and posterior CTV borders in high-risk or recurrent patients might be a reasonable approach for increasing coverage. However, additional data in more homogeneous populations with localized disease are needed before routine application.

    24 selected urban middle class low risk preterm infants and 10 full term infants have been followed up to the age of 7 years in a prospective neurodevelopmental study. The aim was to find out whether the neurological and behavioral peculiarities of the preterm infant fall within the range of variability of sign and function development or whether they are the clinical features of minor neurological dysfunction. The infants were assessed neurologically according to Amiel-Tison at 3, 6, 9 and 12 months of corrected age and by Touwen's examination for minor neurological dysfunction at 3, 5 and 7 years. They were assessed psychologically at 6, 9, 12 and 36 months on Griffiths' Developmental Scale and at 7 years on the Wechsler Bellevue Scale. 33% of the sample was lost to follow-up. The outcome of neurological assessment was as follows: no major sequelae such as cerebral palsy or mental deficiency; 50% had transient neurological anomalies (TNA) during the first year of life, lasting more than 6 months in 16.7%; no minor neurological dysfunctions were detected at 5 and 7 years but the non optimal signs scores were higher in infants of low gestational age. The scores on the Griffiths scale were poorer in the preterm infants between 6 months and 5 years of corrected age, especially in the performance and hearing-speech areas. Performance failures seemed to be related to the duration and type of TNA in the first year of life. General, verbal and performance quotients on the WISC at 7 years were normal and there were no learning or behavior problems. The mild TNA found in low risk preterm infants in the first year of life appear to be of no predictive value for school age problems.

    Full Text Available Background: Nosocomial meningitis is a rare complication following neurosurgical procedures and is associated with high morbidity and mortality. Aim: The aim of this study was to describe the clinical characteristics and the risk factors associated with mortality in patients who developed nosocomial meningitis following neurosurgical operations. Setting and design: Tertiary care hospital and an observational study. Materials and Methods: The study subjects included 2265 patients who underwent various neurosurgical operations during 2003-05. The diagnosis of nosocomial meningitis was based on the Center for Disease Control criteria. Statistical analysis: It was performed by using Statistical Package for Social Sciences for Windows 10.0 program. Results: The incidence of postoperative nosocomial meningitis was 2.7% (62 episodes in 49 patients among 2265 patients operated. Staphylococcus aureus and Acinetobacter spp. were the most frequently isolated pathogens. Of the 49 with meningitis 20 (40.8% patients died. In the logistic regression analysis model, Glascow coma scale score less than 10 (Odds Ratio (OR: 19.419, 95% Confidence Interval (CI; 1.637-230.41, P = 0.001, and low cerebrospinal fluid glucose level (≤ 30 mg/ dL (OR: 10.272, 95% CI; 1.273-82.854, P = 0.002, and presence of concurrent nosocomial infection (OR: 28.744, 95% CI;1.647-501.73, P =0.001 were the independent risk factors associated with mortality. Conclusion: The mortality in patients who developed meningitis was high. The high percentage of concurrent nosocomial infections was associated with a high mortality rate which was a serious problem.
