    Women at hereditary risk of breast cancer face a difficult clinical decision. Each of the options available to them has unique advantages and disadvantages that are summarized in Table 9. Many components enter a high-risk woman's decision: her objective risk of breast cancer; clinical features, such as the consistency of breast tissue and resultant ease of examination; breast density on mammography; personal characteristics, including her experience with cancer within her family; her role and [table: see text] responsibilities within her own nuclear family; her values and goals; her experiences with the medical system; and her subjective assessment of risk. It is generally believed that women significantly overestimate their risk of breast cancer. Thus, it is vital that a woman at risk have access to a genetic counselor who can provide accurate assessment of her risk. Women should be encouraged to take time to understand their risk level and the advantages and disadvantages of the options before them.

    The research about follow-up patterns of women attending high-risk breast-cancer clinics is sparse. This study sought to profile daughters of breast-cancer patients who are likely to return versus those unlikely to return for follow-up care in a high-risk clinic. Our investigation included 131 patients attending the UCLA Revlon Breast Center High Risk Clinic. Predictor variables included age, computed breast-cancer risk, participants' perceived personal risk, clinically significant depressive symptomatology (CES-D score ≥ 16), current level of anxiety (State-Trait Anxiety Inventory), and survival status of participants' mothers (survived or passed away from breast cancer). A greater likelihood of reattendance was associated with older age (adjusted odds ratio [AOR] = 1.07, p = 0.004), computed breast-cancer risk (AOR = 1.10, p = 0.017), absence of depressive symptomatology (AOR = 0.25, p = 0.009), past psychiatric diagnosis (AOR = 3.14, p = 0.029), and maternal loss to breast cancer (AOR = 2.59, p = 0.034). Also, an interaction was found between mother's survival and perceived risk (p = 0.019), such that reattendance was associated with higher perceived risk among participants whose mothers survived (AOR = 1.04, p = 0.002), but not those whose mothers died (AOR = 0.99, p = 0.685). Furthermore, a nonlinear inverted "U" relationship was observed between state anxiety and reattendance (p = 0.037); participants with moderate anxiety were more likely to reattend than those with low or high anxiety levels. Demographic, medical, and psychosocial factors were found to be independently associated with reattendance to a high-risk breast-cancer clinic. Explication of the profiles of women who may or may not reattend may serve to inform the development and implementation of interventions to increase the likelihood of follow-up care.

    Smell identification deficits exist in schizophrenia, and may be associated with its negative symptoms. Less is known about smell identification and its clinical correlates in individuals at clinical high risk (CHR) for schizophrenia and related psychotic disorders. We examined smell identification, symptoms and IQ in 71 clinical high-risk (CHR) subjects and 36 healthy controls. Smell identification was assessed using both the 40-item University of Pennsylvania Smell Identification Test (UPSIT; Doty, R.L., Shaman, P., Kimmelman, C.P., Dann, M.S., 1984. University of Pennsylvania Smell Identification Test: a rapid quantitative olfactory function test for the clinic. Laryngoscope 94, 176-178) and its extracted 12-item Brief Smell Identification Test (Goudsmit, N., Coleman, E., Seckinger, R.A., Wolitzky, R., Stanford, A.D., Corcoran, C., Goetz, R.R., Malaspina, D., 2003. A brief smell identification test discriminates between deficit and non-deficit schizophrenia. Psychiatry Research 120, 155-164). Smell identification did not significantly differ between CHR subjects and controls. Among CHR subjects, smell identification did not predict schizophrenia (N=19; 27%) within 2 years, nor was it associated with negative or positive symptoms. This is the third prospective cohort study to examine smell identification in CHR subjects, and overall, findings are inconclusive, similar to what is found for other disorders in adolescents, such as autism spectrum, attention deficit and anxiety disorders. Smell identification deficit may not have clear utility as a marker of emergent schizophrenia and related psychotic disorders. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    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. Fifty young people at CHR for psychosis were administered the Childhood Trauma Questionnaire with added questions about cyberbullying. Cyberbullying was reported in 38% of the sample. Those who experienced cyberbullying also reported experiencing previous trauma. 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. © 2013 Wiley Publishing Asia Pty Ltd.

    A large body of literature has documented facial emotion perception impairments in schizophrenia. More recently, emotion perception has been investigated in persons at genetic and clinical high-risk for psychosis. This study compared emotion perception abilities in groups of young persons with schizophrenia, clinical high-risk, genetic risk and healthy controls. Groups, ages 13-25, included 24 persons at clinical high-risk, 52 first-degree relatives at genetic risk, 91 persons with schizophrenia and 90 low risk persons who completed computerized testing of emotion recognition and differentiation. Groups differed by overall emotion recognition abilities and recognition of happy, sad, anger and fear expressions. Pairwise comparisons revealed comparable impairments in recognition of happy, angry, and fearful expressions for persons at clinical high-risk and schizophrenia, while genetic risk participants were less impaired, showing reduced recognition of fearful expressions. Groups also differed for differentiation of happy and sad expressions, but differences were mainly between schizophrenia and control groups. Emotion perception impairments are observable in young persons at-risk for psychosis. Preliminary results with clinical high-risk participants, when considered along findings in genetic risk relatives, suggest social cognition abilities to reflect pathophysiological processes involved in risk of schizophrenia.

    2016-11-01

    This review aims to describe the importance of i) detecting individuals at clinical high-risk for psychosis (schizophrenia) or bipolar disorder, especially in children and adolescents, in order to enable early intervention, and ii) evaluating different intervention strategies, especially pharmacotherapy, during the subsyndromal or "prodromal" stages of these severe and often debilitating disorders. The different approaches regarding the psychotic and bipolar clinical high-risk state are discussed, including reasons and evidence for early (pharmacological) intervention and risks of treatment vs. non-treatment. Only 10 prospective studies of antipsychotics (randomized=4) and 6 prospective studies of non-antipsychotic pharmacologic agents (randomized=3, i. e., omega-3 fatty acids=2, glycine=1) for the psychotic clinical high-risk state and only 4 prospective studies of mood stabilizing medications for the bipolar clinical high-risk state (randomized=2, i. e., lithium=1, valproate=1) were detected. Based on the minimal efficacy data, adverse effect risks, especially in pediatric populations, nonspecific psychopathology, and unknown true risk for the development of either psychosis or bipolar disorder or of chronically disabling symptoms and disability, medication treatment currently remains second choice after psychosocial intervention. Additional research in this area is clearly needed in order to shed more light on the relevance and predictive value of potentially prodromal symptoms, their identification and most appropriate management options. © Georg Thieme Verlag KG Stuttgart · New York.

    Early identification of individuals who will go on to develop schizophrenia is a difficult endeavor. The variety of symptoms experienced by clinical high-risk youth make it difficult to identify who will eventually develop schizophrenia in the future. Efforts are being made, therefore, to more accurately identify at-risk individuals and factors that predict conversion to psychosis. As in most assessments of children and adolescents, however, both youth and parental report of symptomatology and resulting dysfunction are important to assess. The goals of the current study were to assess the extent of cross-informant agreement on the Structured Interview for Prodromal Symptoms (SIPS), a widely-used tool employed to determine clinical high-risk status. A total of 84 youth-caregiver pairs participated. Youth and caregiver raters displayed moderate overall agreement on SIPS-rated symptoms. Both youth and caregiver ratings of youth symptomatology contributed significantly to predicting conversion to psychosis. In addition, youth age and quality of youth-caregiver relationships appear to be related to cross-informant symptom ratings. Despite differences on individual SIPS domains, the majority of dyads agreed on youth clinical high-risk status. Results highlight the potential clinical utility of using caregiver informants to determine youth psychosis risk. PMID:24092494

    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.

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

    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.

  20. DNA Methylation-Guided Prediction of Clinical Failure in High-Risk Prostate Cancer.

    Directory of Open Access Journals (Sweden)

    Kirill Litovkin

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    This study sought to develop a clinical model that identifies patients with and without high-risk coronary artery disease (CAD). Although current clinical models help to estimate a patient's pre-test probability of obstructive CAD, they do not accurately identify those patients with and without high-risk coronary anatomy. Retrospective analysis of a prospectively collected multinational coronary computed tomographic angiography (CTA) cohort was conducted. High-risk anatomy was defined as left main diameter stenosis ≥50%, 3-vessel disease with diameter stenosis ≥70%, or 2-vessel disease involving the proximal left anterior descending artery. Using a cohort of 27,125, patients with a history of CAD, cardiac transplantation, and congenital heart disease were excluded. The model was derived from 24,251 consecutive patients in the derivation cohort and an additional 7,333 nonoverlapping patients in the validation cohort. The risk score consisted of 9 variables: age, sex, diabetes, hypertension, current smoking, hyperlipidemia, family history of CAD, history of peripheral vascular disease, and chest pain symptoms. Patients were divided into 3 risk categories: low (≤7 points), intermediate (8 to 17 points) and high (≥18 points). The model was statistically robust with area under the curve of 0.76 (95% confidence interval [CI]: 0.75 to 0.78) in the derivation cohort and 0.71 (95% CI: 0.69 to 0.74) in the validation cohort. Patients who scored ≤7 points had a low negative likelihood ratio (risk CAD was 1% in patients with ≤7 points and 16.7% in those with ≥18 points. We propose a scoring system, based on clinical variables, that can be used to identify patients at high and low pre-test probability of having high-risk CAD. Identification of these populations may detect those who may benefit from a trial of medical therapy and those who may benefit most from an invasive strategy.

    Background Patients with schizophrenia have a decreased ability to interpret the intentions of other individuals, called Theory of Mind (ToM). As capacity for ToM normally advances with brain maturation, research on ToM in individuals at heightened clinical risk for psychosis may reveal developmental differences independent of disease based differences. Methods We examined ToM in at clinical high risk and schizophrenia patients as well as healthy controls: 1) 63 clinical high risk (CHR) patients and 24 normal youths ascertained by a CHR program; and 2) in 13 schizophrenia cases and 14 normal adults recruited through a schizophrenia program. ToM measures included first- and second-order false belief cartoon tasks (FBT) and two “higher order” tasks (“Strange Stories Task” (SST) and the “Reading the Mind in the Eyes” task). In the first study, CHR patients and normal youths were also assessed for cognition, “prodromal” symptoms and social function. Results Errors on first- and second-order false belief tasks were made primarily by patients. CHR patients and their young comparison group had equivalent performance on higher order ToM, which was not significantly different from the worse ToM performance of schizophrenia patients and the higher performance of normal adult controls. In the combined dataset from both studies, all levels of ToM were associated with IQ, controlling for age and sex. ToM bore no relation to explicit memory, prodromal symptoms, social function, or later transition to psychosis. Conclusions Higher order ToM capacity was equally undeveloped in high risk cases and younger controls, suggesting performance on these tasks is not fully achieved until adulthood. This study also replicates the association of IQ with ToM performance described in previous studies of schizophrenia. PMID:21757324

    Recent studies suggest that psychotic-like experiences may also act as markers for non-psychotic psychiatric disorders, which may indicate that the focus of research in individuals at high risk (HR) for psychosis needs updating. In this study we thoroughly examined the clinical and functional characteristics of a consecutive cohort of young people at HR for psychosis and compared them to a matched sample of healthy volunteers. Between February 2010 and September 2012 60 help-seeking HR individuals, aged 16-35, were recruited from CAMEO Early Intervention in Psychosis Service, Cambridgeshire, UK. Forty-five age- and gender-matched healthy volunteers were randomly recruited from the same geographical area. Sociodemographic, psychiatric morbidity, functioning and quality of life measures were compared between both groups. HR individuals suffered a wide range of DSM-IV psychiatric disorders, mainly within the affective and anxiety diagnostic spectra. In comparison to healthy volunteers, young people at HR reported more suicidal ideation/intention, depressive and anxiety symptoms and presented with remarkably poor functioning and quality of life. The presence of co-morbid moderate or severe depressive and anxiety symptoms was common in our sample of young people at enhanced risk for psychosis. A HR mental state may be associated not only with an increased risk for psychosis, but also other psychiatric disorders. Our findings may have implications for the future implementation of therapeutic interventions that this population could benefit from. Copyright © 2013 Elsevier B.V. All rights reserved.

    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.

    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.

    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.

    Background Characterizing neuropsychological (NP) functioning of individuals at clinical high risk (CHR) for psychosis may be useful for prediction of psychosis and understanding functional outcome. The degree to which NP impairments are associated with general cognitive ability and/or later emergence of full psychosis in CHR samples requires study with well-matched controls. Methods We assessed NP functioning across eight cognitive domains in a sample of 73 CHR youth, 13 of whom developed psychotic-level symptoms after baseline assessment, and 34 healthy comparison (HC) subjects. Groups were matched on age, sex, ethnicity, handedness, subject and parent grade attainment, and median family income, and were comparable on WRAT-3 Reading, an estimate of premorbid IQ. Profile analysis was used to examine group differences and the role of IQ in profile shape. Results The CHR sample demonstrated a significant difference in overall magnitude of NP impairment but only a small and nearly significant difference in profile shape, primarily due to a large impairment in olfactory identification. Individuals who subsequently developed psychotic-level symptoms demonstrated large impairments in verbal IQ, verbal memory and olfactory identification comparable in magnitude to first episode samples. Conclusions CHR status may be associated with moderate generalized cognitive impairments marked by some degree of selective impairment in olfaction and verbal memory. Impairments were greatest in those who later developed psychotic symptoms. Future study of olfaction in CHR samples may enhance early detection and specification of neurodevelopmental mechanisms of risk. PMID:20692125

    Schizophrenia and related psychotic disorders are associated with significant neuropsychological (NP) impairments. Yet the onset and developmental evolution of these impairments remains incompletely characterized. This study examined NP functioning over one year in a sample of youth at clinical high risk (CHR) for psychosis participating in a treatment study. We assessed functioning across six cognitive domains at two time points in a sample of 53 CHR and 32 healthy comparison (HC) subjects. Linear regression of HC one-year scores was used to predict one-year performance for CHR from baseline scores and relevant demographic variables. We used raw scores and MANOVAs of the standardized residuals to test for progressive impairment over time. NP functioning of CHR at one year fell significantly below predicted levels. Effects were largest and most consistent for a failure of normative improvement on tests of executive function. CHR who reached the highest positive symptom rating (6, severe and psychotic) on the Structured Interview of Prodromal Syndromes after the baseline assessment (n = 10/53) demonstrated a particularly large (d= −1.89), although non-significant, discrepancy between observed and predicted one-year verbal memory test performance. Findings suggest that, although much of the cognitive impairment associated with psychosis is present prior to the full expression of the psychotic syndrome, some progressive NP impairments may accompany risk for psychosis and be greatest for those who develop psychotic level symptoms.

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

    Directory of Open Access Journals (Sweden)

    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.

    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%.

    The purpose of this study was to evaluate the utility of a breast cancer risk assessment (BCRA) at the time of screening mammogram. Women whose BCRA indicated a high risk for cancer received a letter with instructions for breast health care and genetic counseling if appropriate. After 6 months this group received surveys to evaluate their risk perception and their recall of, and compliance with, recommendations. We also explored the impact of other variables such as a recommendation for genetic counseling and physician communication with the women. After the BCRA, the majority of high risk women reported no change in their perceived risk of cancer. A woman's perceived risk of cancer after a BCRA was significantly associated with her recall of recommendations for breast health care, but not with compliance. A recommendation for genetic counseling was not significantly related to women's perceived risk of cancer after the BCRA. Ten percent of women who should have obtained genetic counseling actually completed an appointment. Women who discussed their BCRA results with their physicians were more compliant with a six month breast exam with a doctor (53% vs 17%, p = 0.018). Overall, women felt that the BCRA was helpful and did not cause undue stress or anxiety. Although the cohort's compliance with recommendations was suboptimal, physicians' interactions with their patients may have a positive influence on their compliance.

    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.

    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.

    Preterm birth (PTB) is the leading cause of perinatal morbidity and mortality. Women with previous prenatal loss are at higher risk of preterm birth. A specialist antenatal clinic is considered as one approach to improve maternity and pregnancy outcomes. A systematic review of quantitative, qualitative and mixed method studies conducted on women at high risk of preterm birth (PTB). The review primary outcomes were to report on the specialist antenatal clinics effect in preventing or reducing preterm birth, perinatal mortality and morbidity and women's perceptions and experiences of a specialist clinic whether compared or not compared with standard antenatal care. Other secondary maternal, infant and economic outcomes were also determined. A comprehensive search strategy was carried out in English within electronic databases as far back as 1980. The reviewers selected studies, assessed the quality, and extracted data independently. Results were summarized and tabulated. Eleven studies fully met the review inclusion criteria, ten were quantitative design studies and only one was a qualitative design study. No mixed method design study was included in the review. All were published after 1989, seven were conducted in the USA and four in the UK. Results from five good to low quality randomised controlled trials (RCTs), all conducted before 1990, did not illustrate the efficacy of the clinic in reducing preterm birth. Whereas results from more recent low quality cohort studies showed some positive neonatal outcomes. Themes from one good quality qualitative study reflected on the emotional and psychological need to reduce anxiety and stress of women referred to such a clinic. Women expressed their negative emotional responses at being labelled as high risk and positive responses to being assessed and treated in the clinic. Women also reported that their partners were struggling to cope emotionally. Findings from this review were mixed. Evidence from cohort studies

    The concurrent use of radiotherapy (RT) and chemotherapy (CT) as adjuvant treatment after surgery in high-risk endometrial cancer has been generally considered cautiously. Recently some of us have reported preliminary data on the efficacy and tolerability of concomitant CT and RT. In this paper, we update our experience. A total of 47 patients aged >18 years and endometrial endometrioid carcinomas entered the study. Inclusion criteria were stages IC G3, IIB, IIIA (patients with positive washing without other unfavourable prognostic factors were omitted), IIIB and IIIC. The radiation plan consisted of a total dose of 50.4 Gy, given in five fractions per week (1.8 Gy: daily dose) for 6 weeks. Paclitaxel (P) at a dose of 60 mg/m(2) was infused intravenously in 250 mL of normal saline for 1 h once weekly during RT for 5 weeks. Three further cycles of Paclitaxel, at a dose of 80 mg/m(2), have been given weekly at the end of RT. There was no life-threatening toxicity. The overall 5-year relapse-free survival was 81.8% (95% CI, 65.2-90.9). The 5-year percent overall disease-specific survival was 88.4% (95% CI, 71.1-95.6). These results, based on a larger series, support our previous data: Paclitaxel plus RT may represent an effective and well-tolerated treatment in high-risk endometrial cancer patients.

    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.

    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.

    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).

    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.

    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.

    Tertiary trauma survey is widely implemented in trauma care to identify all injuries in trauma patients. However, various studies consistently show that some trauma patients have missed injuries. In this study, we developed a clinical decision model to identify patients who are at risk for delayed diagnosed injuries. During a period of 18 months, we collected the medical records of all the adult patients who presented after a high-energy trauma at the emergency department of a Dutch trauma centre. The type of trauma, patient characteristics, the radiology studies performed, Glasgow Coma Scale, Revised Trauma Score, and Injury Severity Score (ISS) were registered. We thoroughly screened all medical records for delayed diagnosed injuries. Stepwise logistic regression analysis was used to identify the variables associated with the outcome delayed diagnosed injuries and to develop a clinical prediction model. We included 475 patients. Thirteen (2.7%) patients with delayed diagnosed injuries were identified. Stepwise logistic regression analysis revealed several models with the ISS, ICU admittance, and CT-head as predictive variables. The model we proposed with the ISS could identify patients who are at a risk for delayed diagnosed injuries with a sensitivity of 92.3% and a specificity of 86.4%. Our newly developed clinical decision model can identify patients who are at a risk for delayed diagnosed injuries and who should undergo an intensified search for potential unidentified injuries.

    Patients with atherosclerotic renovascular disease (ARVD) and high-risk clinical presentations have largely been excluded from randomized controlled trials comparing renal revascularization and optimal medical therapy. Here, we explore the effect of revascularization on death, progression to end-stage kidney disease (ESKD) and cardiovascular events (CVE) in a highly selected cohort of patients with ARVD. All patients with a radiological diagnosis of ARVD referred to our tertiary centre have been recruited into a single-centre cohort study between 1986 and 2014. Patients with ≥70% unilateral or bilateral ARVD together with one or more of the following putative high-risk presentations were designated 'high-risk': flash pulmonary oedema (FPE), severe hypertension, rapidly deteriorating renal function. The effect of revascularization on clinical outcomes in high-risk patients, patients with bilateral severe ARVD and those with <1 g proteinuria at baseline was compared with 'control' patients who had the same degree of renal artery stenosis (RAS) but did not exhibit these features. Median follow-up was 58.4 months [interquartile range (IQR) 25.4-97.3]. Revascularization was associated with a reduced risk of progression to ESKD, CVE and all combined events in patients with rapidly deteriorating renal function [ESKD: hazard ratio (HR) 0.47 (95% confidence interval, CI, 0.25-0.85), P = 0.01; CVE: HR 0.51 (95% CI 0.29-0.91), P = 0.02; Any: HR 0.51 (95% CI 0.29-0.90), P = 0.02]. High-risk patients with bilateral ≥70% RAS and those with <1 g/day baseline proteinuria also had significantly better renal and cardiovascular outcomes post-revascularization when compared with controls. Our results indicate that revascularization may be of benefit in patients with anatomically significant RAS who present with rapidly deteriorating renal function, especially in the presence of severe bilateral ARVD or <1 g/day proteinuria.

  15. 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.

    The purpose of this investigation was to examine the methodology of clinical trials used by the U.S. Food and Drug Administration (FDA) to determine the safety and effectiveness of high-risk orthopaedic devices approved between 2001 and 2015. Utilizing the FDA's online public database, this systematic review audited study design and methodological variables intended to minimize bias and confounding. An additional analysis of blinding as well as the Checklist to Evaluate a Report of a Nonpharmacological Trial (CLEAR NPT) was applied to the randomized controlled trials (RCTs). Of the 49 studies, 46 (94%) were prospective and 37 (76%) were randomized. Forty-seven (96%) of the studies were controlled in some form. Of 35 studies that reported it, blinding was utilized in 21 (60%), of which 8 (38%) were reported as single-blinded and 13 (62%) were reported as double-blinded. Of the 37 RCTs, outcome assessors were clearly blinded in 6 (16%), whereas 15 (41%) were deemed impossible to blind as implants could be readily discerned on imaging. When the CLEAR NPT was applied to the 37 RCTs, >70% of studies were deemed "unclear" in describing generation of allocation sequences, treatment allocation concealment, and adequate blinding of participants and outcome assessors. This study manifests the highly variable reporting and strength of clinical research methodology accepted by the FDA to approve high-risk orthopaedic devices.

    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.

    Hypertension management and control still represents a major clinical challenge for physicians, as well as for National Health Care Systems, since high blood pressure (BP) levels in treated uncontrolled outpatients are related to a persistently increased risk of cardiovascular (CV) events. The Italian Society of Hypertension (SIIA) has prompted several educational interventions for improving BP control in Italy. To evaluate clinical attitudes and preferences of large community sample of both specialized physicians and general practitioners, included in an educational program, endorsed by SIIA and aimed at improving interventions for achieving better BP control in Italy. A predefined questionnaire, which included a main body with 17 questions and 15 specific items (3-4 questions for each item), was anonymously administered to a large community sample of physicians who have practice in managing outpatients with hypertension and high CV risk profile. Both specialized physicians and general practitioners, distributed throughout the whole Italian territory, have been included in this educational program. Data were reported into a computerised spreadsheet and centrally analysed. Confidentiality of the data were guaranteed during each phase of the study. From a total of 64 questions, 557 physicians (478 male, mean age 54.2 ± 7.1 years, average age of medical activity 28.0 ± 8.1 years), among which 261 (46.9 %) specialised physicians and 296 (53.1 %) general practitioners, provided 60,713 answers to the survey questionnaire. Physicians devote time and effort for achieving the recommended BP targets (high risk subgroups), yet they reported a very high rate of BP control (about 70 %). Concomitant presence of diabetes, cardiac and renal organ damage (35-50 %), as well as comorbidities (20-35 %), is reported to be high and able to impact on antihypertensive treatment's efficacy. Appropriate BP assessment is also viewed as a key tool for verifying effectiveness of a given

    Antenatal care is aiming to reduce maternal land foetal mortality and morbidity. Maternal and foetal mortality can be due to different causes. Their knowledge allows identifying pregnancy (high risk pregnancy) with factors associated with an increased risk for maternal and/or foetal mortality and serious morbidity. Identification of high risk pregnancies and initiation of appropriate treatment and/or surveillance should improve maternal and/or foetal outcome. New risk factors are continuously described thanks to improvement in antenatal care and development in biology and cytopathology, increasing complexity in identifying high risk pregnancies. Level of risk can change all over the pregnancy. Ideally, it should be evaluated prior to the pregnancy and at each antenatal visit. Clinical examination is able to screen for intra-uterin growth restriction, pre-eclampsia, threatened for preterm labour; ultrasounds help in the diagnosis of foetal morphological anomalies, foetal chromosomal anomalies, placenta praevia and abnormal foetal growth; biological exams are used to screen for pre-eclampsia, gestational diabetes, trisomy 21 (for which screening method just changed), rhesus immunisation, seroconversion for toxoplasmosis or rubeola, unknown infectious disease (syphilis, hepatitis B, VIH). During pregnancy, most of the preventive strategies have to be initiated during the first trimester or even before conception. Prevention for neural-tube defects, neonatal hypocalcemia and listeriosis should be performed for all women. On the opposite, some measures are concerning only women with risk factors such as prevention for toxoplasmosis, rhesus immunization (which recently changed), tobacco complications and pre-eclampsia and intra-uterine growth factor restriction.

    Full Text Available Background. Cardiac troponin levels have been reported to add value in the detection of cardiovascular complications in noncardiac surgery. A sensitive cardiac troponin I (cTnI assay could provide more accurate prognostic information. Methods. This study prospectively enrolled 142 patients with at least one Revised Cardiac Risk Index risk factor who underwent noncardiac surgery. cTnI levels were measured postoperatively. Short-term cardiac outcome predictors were evaluated. Results. cTnI elevation was observed in 47 patients, among whom 14 were diagnosed as having myocardial infarction (MI. After 30 days, 16 patients had major adverse cardiac events (MACE. Excluding patients with a final diagnosis of MI, predictors of cTnI elevation included dialysis, history of heart failure, transoperative major bleeding, and elevated levels of pre- and postoperative N-terminal pro-B-type natriuretic peptide (NT-proBNP. Maximal cTnI values showed the highest sensitivity (94%, specificity (75%, and overall accuracy (AUC 0.89; 95% CI 0.80–0.98 for postoperative MACE. Postoperative cTnI peak level (OR 9.4; 95% CI 2.3–39.2 and a preoperative NT-proBNP level ≥917 pg/mL (OR 3.47; 95% CI 1.05–11.6 were independent risk factors for MACE. Conclusions. cTnI was shown to be an independent prognostic factor for cardiac outcomes and should be considered as a component of perioperative risk assessment.

    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

    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.

    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)

    We sought to determine the clinical utility and cost of repeating syphilis testing in the third trimester of pregnancy in a high-risk urban population. A retrospective cohort analysis was performed for patients delivering from January 1993 through December 2009 with at least 1 venereal disease research laboratory (VDRL) test sent during pregnancy. Chart review was performed for patients with confirmed syphilis to determine the temporal relationship of syphilis diagnosis to the pregnancy. For patients who seroconverted during pregnancy (no antecedent history or treatment for syphilis), newborn charts were reviewed. The costs of treating seropositive neonates and the costs of implementing additional third-trimester syphilis screening were then compared. In the 17-year cohort, 58,569 deliveries were available for analysis. In all, 113 new cases of syphilis occurred (192.9/100,000 deliveries). There were 17 detected seroconversions; 10 were not rescreened in the third trimester and tested positive at delivery. These 10 patients may have benefitted from implementing uniform VDRL testing at 28-32 weeks' gestation. All newborns were asymptomatic with a negative workup and received empiric penicillin therapy. Based on 2011 hospital charges, the cost of evaluating and treating a neonate for syphilis is $11,079. Implementing an additional VDRL screen at 28-32 weeks' gestation for each pregnant patient during the 17 years studied would cost $1,991,346. An 18-fold increase in syphilis prevalence (3500/100,000 [3.5%] deliveries) would be required for the cost of implementation of universal early third-trimester screening to be equal to the potential health care charges saved by detecting maternal seroconversion and obviating the need for neonatal therapy. In this high-risk population, additional syphilis screening in the third trimester is costly and is not clinically helpful in detecting maternal seroconversion. Copyright © 2014 Mosby, Inc.

    The effects of persistent Plasmodium falciparum (Pf) infection and multiclonality on subsequent risk of clinical malaria have been reported, but the relationship between these 2 parameters and their relative impacts on the clinical outcome of infection are not understood. A longitudinal cohort study was conducted in a seasonal and high-transmission area of Mali, in which 500 subjects aged 1–65 years were followed for 1 year. Blood samples were collected every 2 weeks, and incident malaria cases were diagnosed and treated. Pf infection in each individual at each time point was assessed by species-specific nested-PCR, and Pf longitudinal prevalence per person (PfLP, proportion of Pf-positive samples over 1 year) was calculated. Multiclonality of Pf infection was measured using a 24-SNP DNA barcoding assay at 4 time-points (two in wet season, and two in dry season) over one year. PfLP was positively correlated with multiclonality at each time point (all r≥0.36; all P≤0.011). When host factors (e.g., age, gender), PfLP, and multiclonality (at the beginning of the transmission season) were analyzed together, only increasing age and high PfLP were associated with reduced clinical malaria occurrence or reduced number of malaria episodes (for both outcomes, P<0.001 for age, and P = 0.005 for PfLP). When age, PfLP and baseline Pf positivity were analyzed together, the effect of high PfLP remained significant even after adjusting for the other two factors (P = 0.001 for malaria occurrence and P<0.001 for number of episodes). In addition to host age and baseline Pf positivity, both of which have been reported as important modifiers of clinical malaria risk, our results demonstrate that persistent parasite carriage, but not baseline multiclonality, is associated with reduced risk of clinical disease in this population. Our study emphasizes the importance of considering repeated parasite exposure in future studies that evaluate clinical malaria risk. PMID:28158202

    The aim of the present study is to compare the performance of several commercial human papillomavirus (HPV) tests in a cohort of 281 women. The hybrid capture II, the PreTect-HPV-Proofer, the linear array, and DR.HPVTMIVD were utilized to detect and type HPV in parallel with in-house PCR tests followed by direct automated sequencing or by sub-cloning and sequencing. The concordance levels along with other tests were evaluated with a Cohen's K value varying between 0.60 to 0.88, indicating good correlation with nearly perfect agreement between hybrid capture II, (HCII) and the linear array test. High sensitivity was recorded by the linear array and HCII with 100% (95% CI, 0.8021 to 1.0000) detection of cervical intraepithelial neoplasia (CIN) III by both methods. Conversely, the PreTect-HPV-Proofer showed high specificity with 12% (95% CI, 0.7966 to 0.9163) positivity on normal samples. The genotyping analysis showed that agreement among tests was only low to moderate with great differences between different HPV types. Multiple infections were detected with poor concordance and sub-cloning assays revealed the presence of a lower number of HPV in comparison to the other methods. In summary, the use of different HPV tests applied to the same group of cervical smears may possibly lead to incongruent results, suggesting the need to standardize type-specific sensitivity of genotyping methods and the need to evaluate their accuracy in detecting multiple HPV infections. This would be a prerequisite for the use of genotyping assays in cervical cancer screening programs.

    Donor-specific antibodies (DSAs) play a fundamental role in kidney transplantation. The identification of DSAs is an essential rejection parameter. We evaluated a protocol in 237 patients receiving kidneys from living (LDs) and deceased donors (DDs). Recipients were classified as being at low (LR), medium (MR), high (HR), or strong (SR) risk of rejection based on Luminex panel reactive antibody (PRA)-single antigen beads (SABs). Grafts that survived for 1 year were evaluated. Of the 237 transplanted patients, 129 (54.43%) received a kidney from an LD and 108 (45.57%) from a DD. Of 95 LR recipients receiving kidneys from LDs, 2 patients lost the graft due to non-immunological causes. Of 34 MR recipients, 13 had rejection episodes, and 2 lost the graft by AMR and one by cellular rejection (CR). Of 108 recipients receiving a kidney from a DD, 59 (54.63%) were LR, 31 (28.70%) MR, 11 (10.19%) HR, and 7 (6.48%) SR. Twenty of all transplanted recipients lost their grafts; 4 were due to clinical causes, 4 by cellular rejection, and 12 by antibody-mediated rejection (AMR) with PRA-SAB mean fluorescent intensity of 530 to 12,591. One-year graft survival for LD transplanted LR and MR patients was 97.6% and 94.1%, respectively (P = .004). In DD recipients, the LR vs MR SD was P = .011, and for LR vs HR + SR it was P = .001. For MR vs HR+SR no SD was found (P = .323). Rejections were detected in 51 patients (21.52%). Graft failure occurred in 16 patients (6.75%). A total of 218 (91.98%) recipients maintained good kidney function after 1 year. This protocol based on fluxogram risk assessment of AMR provided fast and precise immunological evaluation of recipients and donors and stratification by immunological risk of AMR.

    Research suggests that social stress exposure influences illness presentation and course among youth at clinical high-risk (CHR) for psychosis, though less is known about the extent to which self-reported perceptions of social stress relate to the severity of positive symptoms. Importantly, despite the notion that youth at CHR are especially susceptible to elevations in positive symptoms under conditions of stress, no study has examined this presumption relative to other psychiatric groups. Extending previous work demonstrating that perceived social stress was higher in a CHR group than in a clinical group of non-CHR, help-seeking controls, the current study aimed to: (1) examine whether perceived social stress is related to the severity of attenuated positive symptoms in the full sample (N=110); and (2) determine whether CHR status moderates the stress-symptom relation. Exploratory analyses examined relations of perceived social stress to negative, disorganized, and general symptoms. Greater perceptions of social stress were associated with more severe positive symptoms in the entire sample; however, although positive symptoms and perceived social stress were higher in the CHR group, the strength of this relation was statistically indistinguishable across groups. No differential effect of perceived social stress was observed for any symptom domain. Results provide some support for the diathesis-stress model of psychosis, while also suggesting that social stress and symptomatology are related independent of clinical vulnerability to psychosis. Future research would benefit from longitudinal studies of stress-symptom relations across CHR and help-seeking control groups. Copyright © 2017 Elsevier B.V. All rights reserved.

    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.

    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.

    Full Text Available Predicting the risk of tuberculosis (TB in people living with HIV (PLHIV using a single test is currently not possible. We aimed to develop and validate a clinical algorithm, using baseline CD4 cell counts, HIV viral load (pVL, and interferon-gamma release assay (IGRA, to identify PLHIV who are at high risk for incident active TB in low-to-moderate TB burden settings where highly active antiretroviral therapy (HAART is routinely provided.A prospective, 5-year, cohort study of adult PLHIV was conducted from 2006 to 2012 in two hospitals in Taiwan. HAART was initiated based on contemporary guidelines (CD4 count < = 350/μL. Cox regression was used to identify the predictors of active TB and to construct the algorithm. The validation cohorts included 1455 HIV-infected individuals from previous published studies. Area under the receiver operating characteristic (ROC curve was calculated.Seventeen of 772 participants developed active TB during a median follow-up period of 5.21 years. Baseline CD4 < 350/μL or pVL ≥ 100,000/mL was a predictor of active TB (adjusted HR 4.87, 95% CI 1.49-15.90, P = 0.009. A positive baseline IGRA predicted TB in patients with baseline CD4 ≥ 350/μL and pVL < 100,000/mL (adjusted HR 6.09, 95% CI 1.52-24.40, P = 0.01. Compared with an IGRA-alone strategy, the algorithm improved the sensitivity from 37.5% to 76.5%, the negative predictive value from 98.5% to 99.2%. Compared with an untargeted strategy, the algorithm spared 468 (60.6% from unnecessary TB preventive treatment. Area under the ROC curve was 0.692 (95% CI: 0.587-0.798 for the study cohort and 0.792 (95% CI: 0.776-0.808 and 0.766 in the 2 validation cohorts.A validated algorithm incorporating the baseline CD4 cell count, HIV viral load, and IGRA status can be used to guide targeted TB preventive treatment in PLHIV in low-to-moderate TB burden settings where HAART is routinely provided to all PLHIV. The implementation of this algorithm will avoid unnecessary

    Full Text Available Background: In bipolar disorder (BD, seasonality of symptoms is common and disturbances in circadian rhythms have been reported. Objectives: We identified high-penetrance families in a geographically restricted area in Northern Fennoscandia and studied the seasonal variation of clinical symptoms among BD subjects and their healthy relatives. Design: We explored the clinical characteristics of subjects living in Northern Fennoscandia, with extreme annual variation in daylight. Among known indigenous high-risk families for BD, we compared the affected ones (N=16 with their healthy relatives (N=15, and also included 18 healthy non-related controls from the same geographical area. Seasonal fluctuation in clinical measures was followed up at the 4 most demarcated photoperiodic time points of the annual cycle: around the summer solstice and autumn equinox in 2013, the winter solstice in 2013/2014, and the spring equinox in 2014. In the baseline, lifetime manic symptoms [Mood Disorder Questionnaire (MDQ] and morningness–eveningness questionnaire type (MEQ were registered, whereas in the follow-up, depressive [Beck Depression Inventory (BDI] and distress [General Health Questionnaire (GHQ-12] symptoms and alcohol consumption and sleep were recorded. Results: Possibly indicative or statistically significant differences in symptoms between the affected subjects and their healthy relatives were the BDI winter (13.3 vs. 2.6, t=−2.51, p=0.022 and spring scores (12.6 vs. 3.2, t=−1.97, p=0.063 and GHQ winter (4.2 vs. 0.82, t=−2.08, p=0.052 and spring scores (3.8 vs. 0.82, t=−1.97, p=0.063. Scores were higher among the affected subjects, exceeding a possibly diagnostic threshold (10 and 3 at all the time points, and without the notable seasonality which was observed among the healthy relatives. In the overall population, MDQ and MEQ scores had an inverse correlation (−0.384, significant at 0.016, indicating increased lifetime manic behaviour among

    There is evidence to suggest that both early traumatic experiences and perceived discrimination are associated with later onset of psychosis. Less is known about the impact these two factors may have on conversion to psychosis in those who are at clinical high risk (CHR) of developing psychosis. The purpose of this study was to determine if trauma and perceived discrimination were predictors of conversion to psychosis. The sample consisted of 764 individuals who were at CHR of developing psychosis and 280 healthy controls. All participants were assessed on past trauma, bullying and perceived discrimination. Individuals at CHR reported significantly more trauma, bullying and perceived discrimination than healthy controls. Only perceived discrimination was a predictor of later conversion to psychosis. Given that CHR individuals are reporting increased rates of trauma and perceived discrimination, these should be routinely assessed, with the possibility of offering interventions aimed at ameliorating the impact of past traumas as well as improving self-esteem and coping strategies in an attempt to reduce perceived discrimination.

    This study was designed to analyze the outcomes of chemotherapy for high-risk gestational trophoblastic neoplasia (GTN) with EMA-CO regimen as primary and secondary protocol in China. Fifty-four patients with high-risk GTN received 292 EMA/CO treatment cycles between 1996 and 2005. Forty-five patients were primarily treated with EMA-CO, and nine were secondarily treated after failure to other combination chemotherapy. Adjuvant surgery and radiotherapy were used in the selected patients. Response, survival and related risk factors, as well as chemotherapy complications, were retrospectively analyzed. Thirty-five of forty-five patients (77.8%) receiving EMA-CO as first-line treatment achieved complete remission, and 77.8% (7/9) as secondary treatment. The overall survival rate was 87.0% in all high-risk GTN patients, with 93.3% (42/45) as primary therapy and 55.6% (5/9) as secondary therapy. The survival rates were significantly different between two groups (chi(2)= 6.434, P =0.011). Univariate analysis showed that the metastatic site and the number of metastatic organs were significant risk factors, but binomial distribution logistic regression analysis revealed that only the number of metastatic organs was an independent risk factor for the survival rate. No life-threatening toxicity and secondary malignancy were found. EMA-EP regimen was used for ten patients who were resistant to EMA-CO and three who relapsed after EMA-CO. Of those, 11 patients (84.6%) achieved complete remission. We conclude that EMA-CO regimen is an effective and safe primary therapy for high-risk GTN, but not an appropriate second-line protocol. The number of metastatic organs is an independent prognostic factor for the patient with high-risk GTN. EMA-EP regimen is a highly effective salvage therapy for those failing to EMA-CO.

    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.

    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.

    Highlights: Black-Right-Pointing-Pointer High-risk human papillomavirus is detected in virtually all-invasive cervical cancers. Black-Right-Pointing-Pointer Electrochemical genosensor for simultaneous detection of multiple high-risk HPV applied to cervical scrape samples. Black-Right-Pointing-Pointer Excellent correlation with HPV genotyping carried out within a hospital laboratory. - Abstract: An electrochemical genosensor array for the simultaneous detection of three high-risk human papillomavirus (HPV) DNA sequences, HPV16, 18 and 45, exhibiting high sensitivity and selectivity is presented. The electrodes of a 4 Multiplication-Sign 4 array were modified via co-immobilization of a 1:100 (mol/mol) mixture of a thiolated probe and an oligoethyleneglycol-terminated bipodal thiol. Detection of synthetic and PCR products was carried out in a sandwich type format, with the target hybridized between a surface immobilized probe and a horseradish peroxidase-labelled secondary reporter probe. The detection limits obtained in the detection of each individual target were in the pM range, allowing the application of this sensor for the detection of samples obtained from PCR amplification of cervical scrape samples. The results obtained exhibited an excellent correlation with the HPV genotyping carried out within a hospital laboratory. Multiplexing and cross-reactivity studies demonstrated high selectivity over potential interfering sequences, facilitating application of the developed platform for the high-throughput screening of multiple high-risk DNA sequences.

    The aim of the study was to assess the clinical value of ultrasound screenings for the developmental dysplasia of the hip (DDH) and explore its etiology in high-risk infants with cerebral palsy in follow-up visits. A group of 98 cases of infants at high-risk of cerebral palsy who received rehabilitation treatment between July, 2009 and July, 2010 were selected. Infants included 58 men and 40 women, aged hips was performed and the infants with abnormalities were given clinical intervention, and 1- to 2-year-old infants were given outpatient follow-ups. The results were analyzed and there were 40 abnormal cases among the 98 cases of infants at high risk of cerebral palsy, including 18 cases of unstable hip joint, and 22 cases of DDH (12 cases of hip dysplasia, 3 cases of hip subluxation and 7 cases of hip dislocation). Early clinical intervention for infants with hip dysplasia and outpatient follow up for infants aged 1-2 years was carried out and had ischemic necrosis of femoral head, with the exception of 1 case of femoral detorsion that was poorly restored. In conclusion, the probability of DDH was higher in infants at high-risk of cerebral palsy compared to the normal infants. Hip ultrasound is a safe, simple, and effective screening method for these infants, which is of great clinical significance for an earlier diagnosis and treatment of DDH in infants with cerebral palsy.

    The total body of evidence finds fluoride varnish effective to prevent caries. However, most trials were conducted in high-risk populations, with more recent trials on low-risk groups finding a lower efficacy. We aimed to assess the cost-effectiveness of fluoride varnish application in clinic setting in populations with different caries risk. A mixed public-private-payer perspective in the context of German health care was performed using a lifetime Markov model. Effectiveness data were derived from an update of the most recent systematic Cochrane review and synthesized in three different risk groups according to control group caries increment via random-effects meta-analysis. Varnish was assumed to be applied twice yearly between age 6 and 18 years. Teeth with carious defects would be treated restoratively and could experience further follow-up treatments. Costs were deduced from German fee item catalogues. Monte Carlo microsimulations were used for to analyse lifetime treatment costs and caries increment (Euro/Decayed, Missing, Filled Teeth (DMFT)). In low-risk groups, fluoride varnish was nearly twice as costly and minimally more effective (293 Euro, 8.1 DMFT) than no varnish (163 Euro, 8.5 DMFT). The incremental cost-effectiveness ratio (ICER) was 343 Euro spent per avoided DMFT. The ICER was lower in medium-risk (ICER 93 Euro/DMFT) and high-risk groups (8 Euro/DMFT). Application of fluoride varnish in the clinic setting is unlikely to be cost-effective in low-risk populations. There is the need to either target high-risk groups or to provide fluoride varnish at lower costs, possibly in nonclinic settings. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We conducted a study designed to evaluate the efficacy and feasibility of a multilevel self-management intervention to improve nutritional intake in a group of older adults receiving Medicare home health services who were at especially high risk for experiencing undernutrition. The Behavioral Nutrition Intervention for Community Elders (B-NICE) trial used a prospective randomized controlled design to determine whether individually tailored counseling focused on social and behavioral aspects of eating resulted in increased caloric intake and improved nutrition-related health outcomes in a high-risk population of older adults. The study was guided by the theoretical approaches of the Ecological Model and Social Cognitive Theory. The development and implementation of the B-NICE protocol, including the theoretical framework, methodology, specific elements of the behavioral intervention, and assurances of the treatment fidelity, as well as the health policy implications of the trial results, are presented in this article.

    A randomized clinical trial was designed to evaluate the effect of daily high-dose xylitol chewing gum on plaque pH and salivary mutans streptococci (MS) in a sample of schoolchildren at high risk of caries. The study was performed on 204 subjects (acceptance rate 88.3%). Inclusion criteria were: >1 and salivary MS concentration >10(5) CFU/ml. Subjects were randomly assigned to the xylitol or control group. Study design included one examination at baseline (t(0)), one after 3 months of chewing (t(1)), one after 6 months of chewing (t(2)) and the last 3 months after the end of chewing period (t(3)). Plaque pH was assessed using the MicroTouch technique, following a sucrose challenge. The area under the curve (AUC(5.7) and AUC(6.2)) was recorded. Whole saliva was collected in sterile vials and MS CFU/ml were counted. Data were analysed using repeated-measures ANOVA. The main result was that plaque acidogenicity was reduced in both groups. The differences between treatments were statistically significant both for plaque pH and MS concentration; the interaction term for treatment and time was statistically significant (p salivary MS concentration >10(5) and those with pH, and that this effect was statistically greater when using xylitol chewing gums, both on plaque pH and MS salivary concentration.

    Full Text Available It is estimated that roughly 20% of pregnancies fall into the high risk category, which in turn are responsible for over 80% of perinatal adverse outcome. Modern obstetrics has been very successful in reducing maternal morbidity and mortality. It has focused mainly on fetal and neonatal aspects, and on identifying the subgroup of pregnant women that need greater surveillance and care because of clearly identifiable risk factors. The article describes the preconceptional advice, its components and recommendations for its implementation, as well as its role in maternal and perinatal risk assessment. These interventions attempt to reduce the rates of maternal and perinatal mortality.

    The prognostic importance of tight clinic blood pressure (BP) control is controversial in diabetic patients. The objective was to investigate the prognostic impact of clinic and ambulatory BPs for cardiovascular morbidity and mortality in type 2 diabetes. In a prospective cohort study, 565 type 2 diabetic patients had clinical, laboratory and ambulatory BP monitoring (ABPM) data obtained at baseline and during follow-up. The primary endpoints were a composite of fatal and nonfatal cardiovascular events and all-cause mortality. Multivariable Cox survival and splines regression analyses assessed associations between each BP component [SBP, DBP and pulse pressure (PP)] and the endpoints. After a median follow-up of 5.75 years, 88 total cardiovascular events and 70 all-cause deaths occurred. After adjustments for cardiovascular risk factors, clinic SBP and DBPs were predictive of the composite endpoint but not of all-cause mortality, whereas all ambulatory BP components were predictors of both endpoints. Ambulatory systolic and PPs were the strongest predictors and achieved ambulatory BPs during follow-up improved risk prediction in relation to baseline values. When categorized at clinically relevant cut-off values, risk began only at clinic BPs at least 140/90 mmHg, whereas for ambulatory BPs it began at lower values (≥120/75 mmHg for the 24-h period). ABPM provides more valuable information regarding cardiovascular risk stratification than office BPs and should be performed, if possible, in every high-risk type 2 diabetic patient. Achieved 24-h ambulatory BPs less than 120/75 mmHg are associated with significant cardiovascular protection and, if confirmed by other studies, may be considered as BP treatment targets.

    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.

    Full Text Available BACKGROUND: Most studies aiming to predict transition to psychosis for individuals at ultra-high risk (UHR have focused on either neurocognitive or clinical variables and have made little effort to combine the two. Furthermore, most have focused on a dichotomous measure of transition to psychosis rather than a continuous measure of functional outcome. We aimed to investigate the relative value of neurocognitive and clinical variables for predicting both transition to psychosis and functional outcome. METHODS: Forty-three UHR individuals and 47 controls completed an extensive clinical and neurocognitive assessment at baseline and participated in long-term follow-up approximately six years later. UHR adolescents who had converted to psychosis (UHR-P; n = 10 were compared to individuals who had not (UHR-NP; n = 33 and controls on clinical and neurocognitive variables. Regression analyses were performed to determine which baseline measures best predicted transition to psychosis and long-term functional outcome for UHR individuals. RESULTS: Low IQ was the single neurocognitive parameter that discriminated UHR-P individuals from UHR-NP individuals and controls. The severity of attenuated positive symptoms was the only significant predictor of a transition to psychosis and disorganized symptoms were highly predictive of functional outcome. CONCLUSIONS: Clinical measures are currently the most important vulnerability markers for long-term outcome in adolescents at imminent risk of psychosis.

    Alcohol use may have a negative impact on the course of HIV disease and the effectiveness of its treatment. We studied patients with HIV who use alcohol and associated socio-demographic, health and psychosocial factors. Outcomes from this study may help in selecting patients from clinical practice with high-risk alcohol use and who are likely to benefit most from alcohol reduction interventions. In a cross sectional study in three primary health care clinics in Pretoria, South Africa, from January 2012 to June 2012, patients with HIV infection were interviewed and patients' medical files were reviewed to obtain data on levels of alcohol use (Alcohol Use Disorder Identification Test), patients' socio-demographic characteristics, HIV-related information, health related quality of life (WHOQoL-HIVBref), internalized AIDS stigma, symptoms of depression and adherence to antiretroviral therapy. Analyses consisted of descriptive statistics, bi- and multivariate logistic regression models. A total of 2230 patients (1483 [66.5%] female) were included. The median age was 37 years (interquartile range 31-43), 99.5% were black Africans, 1975 (88.6%) had started ART and the median time on ART was 22 months (interquartile range 9-40). No alcohol was used by 64% of patients, 8.9% were low risk drinkers, 25.1% of patients were hazardous or harmful drinkers and 2.0% had possible alcohol dependence. In multivariate analysis high-risk drinking was positively associated with male gender, never being married, tobacco use, a higher score for the 'level of independence'-domain measured with the WHOQoL-HIVBref questionnaire, and with more depressive symptoms compared to low-risk drinking. This study shows a high prevalence of hazardous or harmful drinking in patients with HIV infection (especially men) attending primary health care clinics in South Africa. Routine screening for alcohol use should be introduced in these clinics and harm reduction interventions should be evaluated, taking

    Individuals with eating disorders (EDs) demonstrate impaired quality of life; however, less than one-third report severe clinical impairment. Thus, it is important to determine factors that may identify those who are most likely to report marked impairment. Perfectionism, emotion dysregulation, and aspects of affective disturbance, such as anxiety and depression, are independently associated with eating pathology and clinical impairment in eating and other disorders. However, little research has explored these three factors concurrently in relation to eating pathology. It is possible that the combined interaction effect of these constructs could be especially harmful. The current study examined the influence of these constructs and their interactions on clinical impairment in college-aged women at high risk for or with a DSM-5 clinical or subclinical ED. Although the three-way interaction of perfectionism, emotion dysregulation, and affective disturbance (i.e., anxiety or depression) was not significant, the two-way interaction between perfectionism and emotion dysregulation was significant such that those who were high in both perfectionism and emotion dysregulation reported the highest levels of clinical impairment. This suggests that the combination of perfectionism and emotion dysregulation may be especially problematic for those with or at high risk for EDs. Interestingly, perfectionism alone was not a predictor of clinical impairment when accounting for the other constructs, implying that perfectionism may have a greater impact when in conjunction with emotion dysregulation. Understanding the impact of combined perfectionistic tendencies and emotion dysregulation on clinical impairment may better inform treatment and more directly target contributors to impaired quality of life.

    Photodynamic therapy (PDT) using aminolevulinic acid or its methyl ester, methyl-aminolevulinate (MAL), is an increasingly recognized approach for treating squamous neoplasia of the skin. Advantages of MAL-PDT include its ability to cover broad diseased areas (field treatment), and to do multiple sessions with little-to-no risk of scarring or mutagenesis. MAL-PDT is especially valuable in certain populations at high risk for skin cancer, including Caucasian patients with extensive solar damage, and organ transplant recipients (OTR) who take immunosuppressive drugs to prevent graft rejection. The latter group has a 65-200 fold increased risk of developing squamous cell carcinoma (SCC), a major cause of mortality. Therapeutic options for those patients, other than frequent surgeries, are very limited. Topical 5-Fluorouracil (5-FU), frequently prescribed in normal patients for pre-SCC of the skin, is only minimally effective in the OTR group. MAL-PDT, however, has ~40% efficacy for pre-SCC in OTR patients. Based upon our preclinical studies in mouse tumor models, which showed that preconditioning with 5-FU can drive higher accumulation of target protoporphyins (PpIX), we proposed a rational combination regimen of 5-FU and MAL-PDT in humans. A clinical trial was designed to test the hypothesis that a combination of 5-FU followed by MAL-PDT will elevate PpIX levels and achieve better clinical outcomes in high-risk OTR patients. Primary endpoints include PpIX levels and biochemical markers (p53) measured noninvasively and in skin biopsies. Lesion clearance and recurrence (via photographs and clinical exam) are secondary endpoints. Ongoing results of this clinical trial are presented.

    Strategies to identify tumors at highest risk for treatment failure are currently under investigation for patients with bladder cancer. We demonstrate that flow cytometric detection of poorly differentiated basal tumor cells (BTCs), as defined by the co-expression of CD90, CD44 and CD49f, directly from patients with early stage tumors (T1-T2 and N0) and patient-derived xenograft (PDX) engraftment in locally advanced tumors (T3-T4 or N+) predict poor prognosis in patients with bladder cancer. Comparative transcriptomic analysis of bladder tumor cells isolated from PDXs indicates unique patterns of gene expression during bladder tumor cell differentiation. We found cell division cycle 25C (CDC25C) overexpression in poorly differentiated BTCs and determined that CDC25C expression predicts adverse survival independent of standard clinical and pathologic features in bladder cancer patients. Taken together, our findings support the utility of BTCs and bladder cancer PDX models in the discovery of novel molecular targets and predictive biomarkers for personalizing oncology care for patients.

    Aim: The study explored fathers’ experience of premature birth during the hospitalization of their infants, analyzing levels of depressive and anxiety symptoms as compared with mothers. Moreover the Italian version of the Clinical Interview for Parents of High-Risk Infant (CLIP) was tested through confirmatory factor analysis. Methods: Couples of parents (N = 64) of preterm infants (gestational age < 37 weeks) were administered a socio-demographic questionnaire, the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory and the CLIP after the admission to the Neonatal Intensive Care Unit (NICU). Results: Significant levels of anxiety and depressive symptoms and high percentages of subjects above the corresponding risk thresholds were found among fathers and mothers with higher scores among the latters. Confirmatory factor analysis of the CLIP showed an adequate structure, with better fit for mothers than for fathers. Conclusion: Results highlighted the importance for nurses and clinicians working in the NICU to consider not only the maternal difficulties but also the paternal ones, even if these are often more hidden and silent. In addition the CLIP may be considered an useful interview for research and clinical purposes to be used with parents of high-risk infants. PMID:26483712

    Brief self-report screening can help facilitate early identification of individuals at risk for or in early stages of psychosis. Existing screening tools focus on self-reported attenuated positive symptoms to detect potential risk; however, parent reports may also be helpful for assessing symptoms, especially in younger patients. Recent evidence has shown that the "atypicality" scale within the self-report form of the Behavior Assessment System for Children, Second Edition (BASC-2) may be useful for identifying high-risk youth within a more clinically comprehensive and potentially minimally stigmatizing format. The BASC-2 parent report form also includes the atypicality scale, but no research has investigated the relation of this scale to psychosis risk. The aim of the current study is to evaluate the association of parent along with youth reports of BASC-2 atypicality with attenuated positive symptoms as assessed by the Structured Interview for Psychosis-Risk Syndromes (SIPS), in a sample of help-seeking adolescents (n=63). Results indicate that both parent and youth reports of atypicality predict clinician-rated symptoms. Moreover, the combination of parent and youth report significantly improved prediction of SIPS scores over either single-informant scale. These findings suggest that parent report scales, as ascertained through part of a larger, commonly used measure, may help identify youth at risk for psychosis, particularly if used in conjunction with youth self-report.

    Preexposure prophylaxis (PrEP) is effective at preventing HIV infection among men who have sex with men (MSM), but there is uncertainty about how to identify high-risk MSM who should receive PrEP. We used a mathematical model to assess the cost-effectiveness of using the HIV Incidence Risk Index for MSM (HIRI-MSM) questionnaire to target PrEP to high-risk MSM. We simulated strategies of no PrEP, PrEP available to all MSM, and eligibility thresholds set to HIRI-MSM scores between 5 and 45, in increments of 5 (where a higher score predicts greater HIV risk). Based on the iPrEx, IPERGAY, and PROUD trials, we evaluated PrEP efficacies from 44% to 86% and annual costs from $5900 to 8700. We designate strategies with incremental cost-effectiveness ratio (ICER) ≤$100,000/quality-adjusted life-year (QALY) as "cost-effective." Over 20 years, making PrEP available to all MSM is projected to prevent 33.5% of new HIV infections, with an ICER of $1,474,000/QALY. Increasing the HIRI-MSM score threshold reduces the prevented infections, but improves cost-effectiveness. A threshold score of 25 is projected to be optimal (most QALYs gained while still being cost-effective) over a wide range of realistic PrEP efficacies and costs. At low cost and high efficacy (IPERGAY), thresholds of 15 or 20 are optimal across a range of other input assumptions; at high cost and low efficacy (iPrEx), 25 or 30 are generally optimal. The HIRI-MSM provides a clinically actionable means of guiding PrEP use. Using a score of 25 to determine PrEP eligibility could facilitate cost-effective use of PrEP among high-risk MSM who will benefit from it most.

    To estimate the persistence rate of high-risk HPV DNA (HR-HPV DNA) in a population treated totally by laser CO2 conization for high-grade cervical intraepithelial neoplasia (HG-CIN), and to examine if this persistence might be considered an independent risk factor for relapsing disease. All women with a histological diagnosis of HG-CIN and planned for laser CO2 conization from January 2003 to December 2004 were prospectively submitted to a HR-HPV test prior to surgery and at three and six months of follow-up. Women providing written informed consent with 24 months of follow-up were enrolled in the study group. A positive HPV test, involvement of resection margins, age at first intercourse, smoking habits, parity and age at conization > 50 years old were considered as risk factors for relapsing HG-CIN during follow-up, and were univariately and multivariately analyzed to discover any independent influencing factors. Of HG-CIN 15.4% resulted not to be HPV related nor relapsing. The HPV clearance rate after treatment was 78.8%. Involvement of resection margins and HR-HPV DNA persistence post-treatment resulted as the only two statistically significant risk factors for HG-CIN recurrence (rate 3.8%). HR-HPV DNA persistence in follow-up resulted to be independent from other risk factors at multivariate analysis. Although able to reach a low recurrence rate of HG-CIN, laser CO2 conization does not remove HPV infection completely from the cervix with a case of persistence in every five treated patients. In our experience this persistence in itself represents an independent risk factor for developing relapsing disease and constitutes the basis to introduce HPV testing even in the follow-up of patients treated for HG-CIN by laser CO2 conization.

    The presence of CD19 in myelomatous plasma cells (MM-PCs) correlates with adverse prognosis in multiple myeloma (MM). Although CD19 expression is upregulated by CD81, this marker has been poorly investigated and its prognostic value in MM remains unknown. We have analyzed CD81 expression by multiparameter flow cytometry in MM-PCs from 230 MM patients at diagnosis included in the Grupo Español de Mieloma (GEM)05>65 years trial as well as 56 high-risk smoldering MM (SMM). CD81 expression was detected in 45% (103/230) MM patients, and the detection of CD81(+) MM-PC was an independent prognostic factor for progression-free (hazard ratio=1.9; P=0.003) and overall survival (hazard ratio=2.0; P=0.02); this adverse impact was validated in an additional series of 325 transplant-candidate MM patients included in the GEM05 <65 years trial. Moreover, CD81(+) SMM (n=34/56, 57%) patients had a shorter time to progression to MM (P=0.02). Overall, our results show that CD81 may have a relevant role in MM pathogenesis and represent a novel adverse prognostic marker in myeloma.

    Although hyperthermic intraperitoneal chemotherapy (HIPEC) has been extensively used to treat patients with peritoneal metastases (PM) from colorectal cancer (CRC), a standard protocol has not yet been established. The aim of this preliminary clinical study was to confirm in vitro the efficacy of mitomycin C combined with 5-fluorouracil (MMC-5FU) under hyperthermic conditions in CRC and investigate the pharmacokinetics and feasibility of HIPEC with MMC-5FU for patients at high risk of PM from CRC. To simulate HIPEC in vitro, we used the collagen gel droplet-embedded culture drug sensitivity test with the HCT166 colorectal cell line to assess the antitumor efficacy of MMC and 5FU as single-agent and combination treatments following incubation with HCT116 cells for 30 min at either 37 or 42°C. In addition, five patients at high risk of PM from CRC underwent surgical tumor resection followed by HIPEC with MMC-5FU. Our results demonstrated that the combined administration of MMC-5FU suppressed tumor cell proliferation more efficiently compared to either agent used alone. In addition, hyperthermia at 42°C significantly enhanced drug sensitivity. During the clinical application of HIPEC with MMC-5FU, no grade 4 hematological toxicities or surgical adverse events were recorded. In addition, there was no evidence of peritoneal recurrence during a median observational period of 38 months. Of note, two patients with positive intraoperative peritoneal cytology at the first surgery developed no peritoneal recurrence and exhibited negative peritoneal cytology at the second surgery. In conclusion, HIPEC using MMC-5FU was shown to be a feasible therapeutic option, with an acceptable toxicity profile, for patients at high risk of PM from CRC. Therefore, HIPEC with MMC-5FU may be a promising novel therapeutic option for such patients, which merits further verification of its safety and efficacy in large-scale clinical trials.

    This study was purposed to compare the clinical efficacy and adverse reactions of low-dose decitabine combined with CAG regimen (aclarubicin, Ara-C, and G-CSF) and CAG regimen alone in intermediate to high-risk myelodysplastic syndromes (MDS), and evaluate the validity and efficacy of the former regimen as new treatment method of intermediate to high-risk myelodysplastic syndromes. A total of 12 patients with intermediate (IR) to high-risk (HR) MDS treated by low-dose decitabine combined with CAG regimen and 10 patients with IR to HR MDS treated by CAG regimen alone were evaluated after treatment of 1 cycle and at least after 2 cycles. The complete remission (CR) after 1 cycle, overall remission rate (ORR), progression free survival (PFS) and overall survival (OS) between them were analyzed. The results showed that 9 patients treated by low-dose decitabine combined with CAG regimen achieved complete remission after 1 cycle, 2 patients achieved partial remission, 1 patient did not show reaction. The complete remission rate was 75.0% and overall response rate was 91.7%. The median time of disease free survival was 9 months (0-27 months). The median overall survival time was 16 months (3-28 months). 4 patients suffered from pulmonary infection after treatment and then were all cured after treatment with anti-infective therapy. The 5 patients treated by CAG regimen alone achieved complete remission,3 patients achieved partial remission, 2 patients showed non-reaction. The complete remission rate was 50.0% and overall response rate was 80.0%. The median time of disease free survival was 6 months(0-18 months). The median overall survival time was 13 months(3-31 months), 4 patients suffered from pulmonary infection, 1 patient suffered from enteric infection and 1 patient suffered from Escherichia coli septicemia after treatment, all of them becomed better after active treatment. Two groups of patients all had no serious adverse reactions, All patients could tolerate, no

    Full Text Available Zheng-Xiong XiNational Institute on Drug Abuse, Intramural Research Program, Baltimore, MD, USAAbstract: Smoking is still the most prominent cause of preventable premature death in the United States and an increasing cause of morbidity and mortality throughout the world. Although the current treatments such as nicotine replacement therapy (NRT and bupropion are effective, long-term abstinence rates are low. Mechanism studies suggest that the pleasurable effects of smoking are mediated predominantly by nicotine, which activates the brain reward system by activation of brain α4β2 nicotinic acetylcholine receptors (nAChRs. Varenicline is a novel α4β2 nAChR partial agonist and has been found to be even more effective than NRT or bupropion in attenuating smoking satisfaction and in relieving craving and withdrawal symptoms after abstinence. Thus, varenicline has been recently approved to be a first-line medication for smoking cessation in the United States and European countries. Varenicline is generally well tolerated in healthy adult smokers, with the most commonly reported adverse effects being nausea, insomnia, and headache. However, growing postmarketing data has linked varenicline to an increase in neuropsychiatric symptoms such as seizures, suicidal attempts, depression, and psychosis as well as serious injuries potentially relating to unconsciousness, dizziness, visual disturbances, or movement disorders. Therefore, new safety warnings are issued to certain high risk populations, such as patients with mental illness and operators of commercial vehicles and heavy machinery. In particular, pilots, air traffic controllers, truck and bus drivers have been banned from taking varenicline.Keywords: nicotine, varenicline, α4β2 nicotinic acetylcholine receptor, nAChRs, partial agonist, smoking cessation

    Current criteria identifying patients with ultra-high risk of psychosis (UHR) have low specificity, and less than one-third of UHR cases experience transition to psychosis within 3 years of initial assessment. We explored whether a Bayesian probabilistic multimodal model, combining baseline historical and clinical risk factors with biomarkers (oxidative stress, cell membrane fatty acids, resting quantitative electroencephalography (qEEG)), could improve this specificity. We analyzed data of a UHR cohort (n=40) with a 1-year transition rate of 28%. Positive and negative likelihood ratios were calculated for predictor variables with statistically significant receiver operating characteristic curves (ROCs), which excluded oxidative stress markers and qEEG parameters as significant predictors of transition. We clustered significant variables into historical (history of drug use), clinical (Positive and Negative Symptoms Scale positive, negative and general scores and Global Assessment of Function) and biomarker (total omega-3, nervonic acid) groups, and calculated the post-test probability of transition for each group and for group combinations using the odds ratio form of Bayes' rule. Combination of the three variable groups vastly improved the specificity of prediction (area under ROC=0.919, sensitivity=72.73%, specificity=96.43%). In this sample, our model identified over 70% of UHR patients who transitioned within 1 year, compared with 28% identified by standard UHR criteria. The model classified 77% of cases as very high or low risk (P>0.9, <0.1) based on history and clinical assessment, suggesting that a staged approach could be most efficient, reserving fatty-acid markers for 23% of cases remaining at intermediate probability following bedside interview.

    The US Food and Drug Administration (FDA) approves high-risk medical devices, those that support or sustain human life or present potential unreasonable risk to patients, via the Premarket Approval (PMA) pathway. The generation of clinical evidence to understand device safety and effectiveness is shifting from predominantly premarket to continual study throughout the total product life cycle. To characterize the clinical evidence generated for high-risk therapeutic devices over the total product life cycle. All clinical studies of high-risk therapeutic devices receiving initial market approval via the PMA pathway in 2010 and 2011 identified through ClinicalTrials.gov and publicly available FDA documents as of October 2014. Studies were characterized by type (pivotal, studies that served as the basis of FDA approval; FDA-required postapproval studies [PAS]; or manufacturer/investigator-initiated); premarket or postmarket; status (completed, ongoing, or terminated/unknown); and design features, including enrollment, comparator, and longest duration of primary effectiveness end point follow-up. In 2010 and 2011, 28 high-risk therapeutic devices received initial marketing approval via the PMA pathway. We identified 286 clinical studies of these devices: 82 (28.7%) premarket and 204 (71.3%) postmarket, among which there were 52 (18.2%) nonpivotal premarket studies, 30 (10.5%) pivotal premarket studies, 33 (11.5%) FDA-required PAS, and 171 (59.8%) manufacturer/investigator-initiated postmarket studies. Six of 33 (18.2%) PAS and 20 of 171 (11.7%) manufacturer/investigator-initiated postmarket studies were reported as completed. No postmarket studies were identified for 5 (17.9%) devices; 3 or fewer were identified for 13 (46.4%) devices overall. Median enrollment was 65 patients (interquartile range [IQR], 25-111), 241 patients (IQR, 147-415), 222 patients (IQR, 119-640), and 250 patients (IQR, 60-800) for nonpivotal premarket, pivotal, FDA-required PAS, and manufacturer

    To enhance indicated prevention in patients with a clinical high risk (CHR) for psychosis, recent research efforts have been increasingly directed towards estimating the risk of developing psychosis on an individual level using multivariable clinical prediction models. The aim of this study was to systematically review the methodological quality and reporting of studies developing or validating such models. A systematic literature search was carried out (up to 14 March 2016) to find all studies that developed or validated a clinical prediction model predicting the transition to psychosis in CHR patients. Data were extracted using a comprehensive item list which was based on current methodological recommendations. A total of 91 studies met the inclusion criteria. None of the retrieved studies performed a true external validation of an existing model. Only three studies (3.5%) had an event per variable ratio of at least 10, which is the recommended minimum to avoid overfitting. Internal validation was performed in only 14 studies (15%) and seven of these used biased internal validation strategies. Other frequently observed modeling approaches not recommended by methodologists included univariable screening of candidate predictors, stepwise variable selection, categorization of continuous variables, and poor handling and reporting of missing data. Our systematic review revealed that poor methods and reporting are widespread in prediction of psychosis research. Since most studies relied on small sample sizes, did not perform internal or external cross-validation, and used poor model development strategies, most published models are probably overfitted and their reported predictive accuracy is likely to be overoptimistic.

    Full Text Available Abstract Background In resource-poor settings, mortality is at its highest during the first 3 months after combination antiretroviral treatment (cART initiation. A clear predictor of mortality during this period is having a low CD4 count at the time of treatment initiation. The objective of this study was to evaluate the effect on survival and clinic retention of a nurse-based rapid assessment clinic for high-risk individuals initiating cART in a resource-constrained setting. Methods The USAID-AMPATH Partnership has enrolled more than 140,000 patients at 25 clinics throughout western Kenya. High Risk Express Care (HREC provides weekly or bi-weekly rapid contacts with nurses for individuals initiating cART with CD4 counts of ≤100 cells/mm3. All HIV-infected individuals aged 14 years or older initiating cART with CD4 counts of ≤100 cells/mm3 were eligible for enrolment into HREC and for analysis. Adjusted hazard ratios (AHRs control for potential confounding using propensity score methods. Results Between March 2007 and March 2009, 4,958 patients initiated cART with CD4 counts of ≤100 cells/mm3. After adjusting for age, sex, CD4 count, use of cotrimoxazole, treatment for tuberculosis, travel time to clinic and type of clinic, individuals in HREC had reduced mortality (AHR: 0.59; 95% confidence interval: 0.45-0.77, and reduced loss to follow up (AHR: 0.62; 95% CI: 0.55-0.70 compared with individuals in routine care. Overall, patients in HREC were much more likely to be alive and in care after a median of nearly 11 months of follow up (AHR: 0.62; 95% CI: 0.57-0.67. Conclusions Frequent monitoring by dedicated nurses in the early months of cART can significantly reduce mortality and loss to follow up among high-risk patients initiating treatment in resource-constrained settings.

    Home testing for chlamydia and gonorrhea increases screening rates, but the cost consequences of this intervention are unclear. We examined the cost differences between home-based and clinic-based testing and the cost-effectiveness of home testing based on the DAISY study, a randomized controlled trial. Direct and indirect costs were estimated for home and clinic testing, and cost-effectiveness was calculated as cost per additional test performed. In the clinic testing group, direct costs were 49/test and indirect costs (the costs of seeking or receiving care) were 62/test. Home testing cost was 25/test. We found that home testing was cost saving when all testing for all patients was considered. However cost savings were not seen when only asymptomatic tests or when patient subgroups were considered. A home testing program could be cost saving, depending on whether changes in clinic testing frequency occur when home testing is available.

    Medication errors are common upon hospital admission. Clinical pharmacist involvement in medication reconciliation is effective in identifying and rectifying medication errors. However, data is lacking on the economic impact, time requirements, and severity of errors resolved by clinical pharmacists. To determine the incidence of unintended admission medication discrepancies resolved by clinical pharmacists. Secondary objectives were to determine the type of discrepancies, potential severity, proximal cause, and economic impact of this clinical pharmacy program. This was a single-center, prospective, observational study conducted at a major teaching medical institution. Following institutional review board approval, data collection was conducted over a 4-week period (August 22, 2011, to September 16, 2011). Descriptive statistical methods were performed for all data analyses. A total of 517 patients involving 5006 medications were included in this study. More than 25% (n = 132) of patients had at least 1 error associated with a medication ordered on hospital admission. Pharmacists resolved a total of 467 admission medication errors (3.5 ± 2.3 errors/patient). The most common type of medication error resolved was medication omission (79.6%). In regard to severity, 46% of medication errors were considered significant or serious. Overall, the mean total time was 44.4 ± 21.8 minutes per medication reconciliation. This clinical pharmacy program was estimated to carry a net present value of $5.7 million over 5 years. Clinical pharmacist involvement within a multidisciplinary health care team during the admission medication reconciliation process demonstrated a significant improvement in patient safety and an economic benefit.

    Cerebral palsy is the most common physical disability in childhood, and is mostly diagnosed after age 2 years. Delays in diagnosis can have negative long-term consequences for children and parents. New guidelines for early cerebral palsy diagnosis and intervention were recently published, after systematic review of the evidence by international multidisciplinary experts aiming to decrease age at diagnosis. The current study tested the feasibility of implementing these guidelines in an American clinical setting. We designed a stepwise implementation process in a neonatal intensive care follow-up clinic. Efficacy was tested by comparing 10-month pre- and post-implementation periods. Clinic visit types, cerebral palsy diagnosis, provider competencies and perspectives, and balancing measures were analyzed. Changes to infrastructure, assessments, scheduling algorithms, documentation and supports in diagnosis or counseling were successfully implemented. Number of three- to four-month screening visits increased (255 to 499, P cerebral palsy care guidelines for infants under age 2 years. We demonstrated for the first time in a US clinical setting the feasibility of implementation of international early diagnosis and treatment guidelines for cerebral palsy. This process is adaptable to other settings and underscores the necessity of future research on cerebral palsy treatments in infancy. Copyright © 2017 The Authors. Published by Elsevier Inc.

    Full Text Available Aim. To assess the real rate of dual antiplatelet therapy (DAT, acetylsalicylic acid + clopidogrel use in patients having appropriate indications according to current clinical guidelines and to study the possibility of prescription rate improvement by education activity directed to doctors. Material and methods. The study consisted of 3 parts. Parts I and II present the results of two questionnaire surveys of patients with acute myocardial infarction, or stenting, who needed in DAT according to current clinical guidelines. The real use of the DAT was assessed in part III on the basis of the multicenter study conducted in different regions of Russia (ROMB study in a large sample of patients having DAT indications. Results. Part I - PROGNOZ-IBS study. According to the questionnaire survey only 112 out of 239 patients (47% having an absolute indications, received DOT. Part II - phone survey of patients with acute myocardial infarction in two towns of Lyubertsy and Podolsk. 28 of 71 patients (39% took the DAT (from some days to 6 months and 35 patients (49% — did not take it. Part III - ROMB study. 519 patients did not take DAT, at that 259 (50% in hospital and 260 (50% - in out-patient clinic. 521 patients took DAT according to indications, at that 238 (46% in hospital and 283 (54% - in out-patient clinic. Conclusion. Less than 50% of patients, having direct indications, received DAT in the real clinical practice. The prescription rate can be improved due to education activity directed to doctors and increase in clopidogrel drugs affordability.

    Full Text Available Background. There is a paucity of research in Australia on the characteristics of women in treatment for illicit substance use in pregnancy and the health outcomes of their neonates. Aims. To determine the clinical features and outcomes of high-risk, marginalized women seeking treatment for illicit substance use in pregnancy and their neonates. Methods. 139 women with a history of substance abuse/dependence engaged with a perinatal drug health service in Sydney, Australia. Maternal (demographic, drug use, psychological, physical, obstetric, and antenatal care and neonatal characteristics (delivery, early health outcomes were examined. Results. Compared to national figures, pregnant women attending a specialist perinatal and family drug health service were more likely to report being Australian born, Aboriginal or Torres Strait Islander, younger, unemployed, and multiparous. Opiates were the primary drug of concern (81.3%. Pregnancy complications were common (61.9%. Neonates were more likely to be preterm, have low birth weight, and be admitted to special care nursery. NAS was the most prevalent birth complication (69.8% and almost half required pharmacotherapy. Conclusion. Mother-infant dyads affected by substance use in pregnancy are at significant risk. There is a need to review clinical models of care and examine the longer-term impacts on infant development.

    Genetic testing for the breast cancer genes 1/2 (BRCA 1/2) has helped women determine their risk of developing breast and ovarian cancer. As interest in genetic testing has grown, companies have created strategies to disseminate information about testing, including direct-to-consumer advertising (DTCA) and online genetic testing. This study examined attitudes toward DTCA and online testing for BRCA among 84 women at a high-risk clinic as well as additional factors that may be associated with these attitudes, such as personal and familial cancer history, cancer worry and risk perception, and history with genetic testing/counseling. Results showed that the majority of the women held favorable attitudes toward DTCA for BRCA testing but did not support online testing. Factors such as familial ovarian cancer, cancer worry, and satisfaction with genetic counseling/testing were associated with positive attitudes toward DTCA, whereas personal breast cancer history was related to negative attitudes. The findings suggest that women may view DTCA as informational but rely on physicians for help in their decision to undergo testing, and also suggest that cancer history may affect women's acceptance of DTCA and genetic testing.

    Bronchiolitis is the leading cause of hospitalization among infants and young children. Because of its frequency, a clinical practice guideline for bronchiolitis was implemented in this population in an effort to decrease costs and the number of diagnostic evaluations performed and medications used without increasing length of stay or transfers to the pediatric intensive care unit. A retrospective chart review of 322 pediatric admissions to a rural community hospital was conducted (169 before guideline implementation and 153 after guideline implementation), and data were categorically stratified into three groups for comparison purposes. Descriptive statistics were used to analyze the data, with a p value bronchiolitis. Statistically significant decreases in cost per day and decreases in use of antibiotics and chest radiographs were achieved without increasing length of stay or pediatric intensive care unit transfers. This project demonstrated feasibility in implementing an evidence-based clinical practice guideline in a rural hospital to improve patient outcomes.

    This is a focused update highlighting the most current NCCN Guidelines for diagnosis and management of Lynch syndrome. Lynch syndrome is the most common cause of hereditary colorectal cancer, usually resulting from a germline mutation in 1 of 4 DNA mismatch repair genes (MLH1, MSH2, MSH6, or PMS2), or deletions in the EPCAM promoter. Patients with Lynch syndrome are at an increased lifetime risk, compared with the general population, for colorectal cancer, endometrial cancer, and other cancers, including of the stomach and ovary. As of 2016, the panel recommends screening all patients with colorectal cancer for Lynch syndrome and provides recommendations for surveillance for early detection and prevention of Lynch syndrome-associated cancers.

    Our purpose was to develop recommendations for contouring the computed tomography (CT)-based high-risk clinical target volume (CTVHR) for 3D image-guided brachytherapy (3D-IGBT) for cervical cancer. A 15-member Japanese Radiation Oncology Study Group (JROSG) committee with expertise in gynecological radiation oncology initiated guideline development for CT-based CTVHR (based on a comprehensive literature review as well as clinical experience) in July 2014. Extensive discussions occurred during four face-to-face meetings and frequent email communication until a consensus was reached. The CT-based CTVHR boundaries were defined by each anatomical plane (cranial-caudal, lateral, or anterior-posterior) with or without tumor progression beyond the uterine cervix at diagnosis. Since the availability of magnetic resonance imaging (MRI) with applicator insertion for 3D planning is currently limited, T2-weighted MRI obtained at diagnosis and just before brachytherapy without applicator insertion was used as a reference for accurately estimating the tumor size and topography. Furthermore, utilizing information from clinical examinations performed both at diagnosis and brachytherapy is strongly recommended. In conclusion, these recommendations will serve as a brachytherapy protocol to be used at institutions with limited availability of MRI for 3D treatment planning.

    Perceived criticism (PC) is a measure of how much criticism from 1 family member "gets through" to another. PC ratings have been found to predict the course of psychotic disorders, but questions remain regarding whether psychosocial treatment can effectively decrease PC, and whether reductions in PC predict symptom improvement. In a sample of individuals at high risk for psychosis, we examined a) whether Family Focused Therapy for Clinical High-Risk (FFT-CHR), an 18-session intervention that consists of psychoeducation and training in communication and problem solving, brought about greater reductions in perceived maternal criticism, compared to a 3-session family psychoeducational intervention; and b) whether reductions in PC from baseline to 6-month reassessment predicted decreases in subthreshold positive symptoms of psychosis at 12-month follow-up. This study was conducted within a randomized controlled trial across 8 sites. The perceived criticism scale was completed by 90 families prior to treatment and by 41 families at 6-month reassessment. Evaluators, blind to treatment condition, rated subthreshold symptoms of psychosis at baseline, 6- and 12-month assessments. Perceived maternal criticism decreased from pre- to posttreatment for both treatment groups, and this change in criticism predicted decreases in subthreshold positive symptoms at 12-month follow-up. This study offers evidence that participation in structured family treatment is associated with improvement in perceptions of the family environment. Further, a brief measure of perceived criticism may be useful in predicting the future course of attenuated symptoms of psychosis for CHR youth.

    The aim of the study was to assess coronary arteries arising from the wrong coronary sinus, including CT-evaluated high-risk anatomic features, clinical symptoms and cardiac events during follow-up. A total of 7,115 patients scheduled for 64-slice or dual-source cardiac CT were screened for the presence of isolated anomalous origin of the coronary artery from the wrong coronary sinus. Anomalous origin of the coronary artery was found in 54 (0.76 %) patients (29 men, 25 women, mean age 60.9 ± 11.6 years). Sixteen (30 %) patients with abnormal right coronary origin (ARCA) more commonly had a slit-like orifice (15 vs. 3; p < 0.001), intramural course (15 vs. 3; p < 0.001) and interarterial course (11 vs. 0; p < 0.001) than 22 (41 %) and 13 (24 %) individuals with abnormal circumflex artery (ALCx) and left coronary artery (ALCA) origin, respectively. Patients with ALCA presented less frequently with chest pain than subjects with ARCA and ALCx (25 vs. 3; p = 0.03). Patients with ARCA tended to show higher occurrence of cardiac events in the follow-up than individuals with ALCA and ALCx (5 vs. 4; p = NS). High-risk anatomy features are most common in patients with ARCA and these patients also have higher prevalence of chest pain and cardiac events in the follow-up than individuals with ALCA and ALCx.

    transcatheter aortic valve implantation (TAVI) has emerged as an alternative to surgical aortic valve replacement for patients with severe aortic stenosis considered inoperable or at high operative risk, but the long-term outcome remains unknown. we assessed the 4-year clinical and echocardiographic outcomes of patients undergoing TAVI with the self-expanding Medtronic CoreValve prosthesis. sixty-three patients (mean age 80 ± 6 years) with severe aortic stenosis (AS) at high risk for surgical aortic valve replacement (Logistic EuroSCORE 28.8 ± 10.9%) were included in this study. all-cause cumulative mortality at 1, 2, 3 and 4 years was 14.3, 25.4, 28.6 and 36.5%, respectively. The cumulative incidence of documented major stroke at 4 years was 6.3%. In survivors, there was a significant improvement in functional status at 4 years. Paravalvular leak (trivial/mild to moderate) was observed in the majority of patients post-TAVI with no case of progression to severe regurgitation at 4-year follow-up. In multivariate analysis, independent predictor for increased all-cause mortality was left ventricular ejection fraction Medtronic CoreValve device. © The Author 2016.

    Full Text Available Abstract Background Genital Human papilloma virus (HPV is one of the most commonly diagnosed Sexually Transmitted Infection (STIs in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico. Methods A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p Results Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%, penile (50.0% and oral (72.6% cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM (OR=2.6;95%CI=1.1-6.1, self-report of genital warts (OR=3.2;95%CI=1.3-7.9 and herpes (OR=7.4;95% CI=2.2-25.1. MSM was marginally associated with adequate knowledge (OR=2.3;95% CI=0.9-5.9 and self-report of herpes remained significantly associated (OR=5.0;95%CI=1.3-18.4 in multivariate logistic regression analysis. Conclusions Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.

    Full Text Available INTRODUCTION: Reduced left ventricular function in patients with severe symptomatic valvular aortic stenosis is associated with impaired clinical outcome in patients undergoing surgical aortic valve replacement (SAVR. Transcatheter Aortic Valve Implantation (TAVI has been shown non-inferior to SAVR in high-risk patients with respect to mortality and may result in faster left ventricular recovery. METHODS: We investigated clinical outcomes of high-risk patients with severe aortic stenosis undergoing medical treatment (n = 71 or TAVI (n = 256 stratified by left ventricular ejection fraction (LVEF in a prospective single center registry. RESULTS: Twenty-five patients (35% among the medical cohort were found to have an LVEF≤30% (mean 26.7±4.1% and 37 patients (14% among the TAVI patients (mean 25.2±4.4%. Estimated peri-interventional risk as assessed by logistic EuroSCORE was significantly higher in patients with severely impaired LVEF as compared to patients with LVEF>30% (medical/TAVI 38.5±13.8%/40.6±16.4% versus medical/TAVI 22.5±10.8%/22.1±12.8%, p <0.001. In patients undergoing TAVI, there was no significant difference in the combined endpoint of death, myocardial infarction, major stroke, life-threatening bleeding, major access-site complications, valvular re-intervention, or renal failure at 30 days between the two groups (21.0% versus 27.0%, p = 0.40. After TAVI, patients with LVEF≤30% experienced a rapid improvement in LVEF (from 25±4% to 34±10% at discharge, p = 0.002 associated with improved NYHA functional class at 30 days (decrease ≥1 NYHA class in 95%. During long-term follow-up no difference in survival was observed in patients undergoing TAVI irrespective of baseline LVEF (p = 0.29, whereas there was a significantly higher mortality in medically treated patients with severely reduced LVEF (log rank p = 0.001. CONCLUSION: TAVI in patients with severely reduced left ventricular function may be

    Little is known about the role of expressed emotion (EE) in early symptom expression in individuals at clinical high risk (CHR) for psychosis. In patients with established schizophrenia, the effects of EE on clinical outcomes have purportedly varied across racial/ethnic groups, but this has not yet been investigated among CHR patients. Furthermore, studies have traditionally focused upon caregiver levels of EE via interview-based ratings, whereas the literature on patient perceptions of caregiver EE on psychosis symptoms is relatively limited. Linear regression models were conducted to examine the impact of criticism and perceived warmth in the family environment, from the CHR patient's perspective, on positive and negative symptom expression in non-Latino white (NLW; n = 38) and Latino (n = 11) adolescents and young adults at CHR for developing psychosis. Analyses examining the sample as a whole demonstrated that perceived levels of maternal criticism were negatively associated with negative CHR symptomatology. Additional analyses indicated that race/ethnicity moderated the relationship between criticism/warmth and clinical symptomatology. We found evidence of a contrasting role of patient perceived criticism and warmth depending upon the patient's race/ethnicity. Family processes shown to impact the course of schizophrenia among NLWs may function differently among Latino than NLW patients. These findings have important implications for the development of culturally appropriate interventions and may aid efforts to improve the effectiveness of mental health services for diverse adolescents and young adults at CHR for psychosis. Given the small sample size of this study, analyses should be replicated in a larger study before more definitive conclusions can be made. © 2014 Wiley Publishing Asia Pty Ltd.

    Full Text Available In 2005, the International Society of Urological Pathology (ISUP introduced several modifications to the original Gleason system that were intended to enhance the prognostic power of Gleason score (GS. The objective of this study was to clinically validate the 2005 ISUP Gleason grading system for its ability to detect metastasis. We queried our institutional RP database for men with NCCN clinically localized intermediate to high-risk disease undergoing radical prostatectomy (RP between 1992 and 2010 with no additional treatment until the time of metastatic progression. A case-cohort design was utilized. A total of 333 available RP samples were re-reviewed and GS was reassigned per the 2005 ISUP Gleason system. Cumulative incidence of metastasis was 0%, 8.4%, 24.5% and 44.4% among specimens that were downgraded, unchanged, had one point GS increase and two point GS increase, respectively. The hazard ratio for metastasis raised in GS 8 and 9 compared to GS 7 from 2.77 and 5.91 to 3.49 and 9.31, respectively. The survival c-index of GS increased from 0.70 to 0.80 when samples were re-graded at 5 years post RP. The c-index of the reassigned GS was higher than the original GS (0.77 vs 0.64 for predicting PCSM at 10 years post RP. The regraded GS improved the prediction of metastasis and PCSM. This validates the updated Gleason grading system using an unambiguous clinical endpoint and highlights the need for reassignment of Gleason grading according to 2005 ISUP system when considering comparisons of novel biomarkers to clinicopathological variables in archival cohorts.

    Full Text Available Purpose: Previous studies comparing percutaneous coronary intervention (PCI with coronary artery bypass graft surgery (CABG in patients with unprotected left main or three-vessel coronary artery disease (LM-3VD have excluded patients at high surgical risk. We compared clinical outcomes after PCI with drug-eluting stents to CABG in high surgical risk patients with LM-3VD. Methods: Patients with symptomatic LM-3VD who had Society of Thoracic Surgeons (STS-predicted operative mortality > 5% and were undergoing either PCI with drug-eluting stents or CABG at a tertiary care center from January 2009 to December 2010 were enrolled in this nonrandomized prospective study. Results: Mean STS score was 14.5 ± 5.8% for PCI (n=83 vs. 13.6 ± 7.1% for CABG (n=187 (P=0.31. After mean follow-up of 37 months, incidence of the composite primary endpoint (death, myocardial infarction or stroke was 42.2% for PCI and 39.6% for CABG (P=0.69, hazard ratio 1.3, 95% confidence interval 0.5-2.8. There were no differences in the individual components of the primary endpoint between PCI and CABG. Repeat revascularization was 30.1% for PCI vs. 9.6% for CABG (P=0.001. Major adverse cardiac and cerebrovascular event rates were similar between PCI and CABG, 50.6% vs. 42.2%, respectively (P=0.23. Patients in the PCI group were less likely than those in the CABG group to be discharged to a nursing home (12.1% vs. 47.1%, P 5%.

    Fibrinogen concentrate might partly restore coagulation defects and reduce intraoperative bleeding. To determine whether fibrinogen concentrate infusion dosed to achieve a plasma fibrinogen level of 2.5 g/L in high-risk cardiac surgery patients with intraoperative bleeding reduces intraoperative blood loss. A randomized, placebo-controlled, double-blind clinical trial conducted in Isala Zwolle, the Netherlands (February 2011-January 2015), involving patients undergoing elective, high-risk cardiac surgery (ie, combined coronary artery bypass graft [CABG] surgery and valve repair or replacement surgery, the replacement of multiple valves, aortic root reconstruction, or reconstruction of the ascending aorta or aortic arch) with intraoperative bleeding (blood volume between 60 and 250 mL suctioned from the thoracic cavity in a period of 5 minutes) were randomized to receive either fibrinogen concentrate or placebo. Intravenous, single-dose administration of fibrinogen concentrate (n = 60) or placebo (n = 60), targeted to achieve a postinfusion plasma fibrinogen level of 2.5 g/L. The primary outcome was blood loss in milliliters between intervention (ie, after removal of cardiopulmonary bypass) and closure of chest. Safety variables (within 30 days) included: in-hospital mortality, myocardial infarction, cerebrovascular accident or transient ischemic attack, renal insufficiency or failure, venous thromboembolism, pulmonary embolism, and operative complications. Among 120 patients (mean age; 71 [SD, 10] years, 37 women [31%]) included in the study, combined CABG and valve repair or replacement surgery comprised 72% of procedures and had a mean (SD) cardiopulmonary bypass time of 200 minutes (83) minutes. For the primary outcome, median blood loss in the fibrinogen group was 50 mL (interquartile range [IQR], 29-100 mL) compared with 70 mL (IQR, 33-145 mL) in the control group (P = .19), the absolute difference 20 mL (95% CI, -13 to 35 mL).

    This multicenter prospective trial assessed the outcome in 63 patients, 40 years of age or younger, with high-risk early breast cancer (HREBC), included in an ovarian protection study. The patients were treated with a luteinizing hormone-releasing hormone (LH-RH) analogue administered for 5 years, tailored chemotherapy and an aromatase inhibitor, in estrogen receptor-positive (ER(+)) patients. T-regulatory cells (T-regs) and vascular endothelial growth factor (VEGF) were measured at baseline and yearly. The mean age of the patients was 36 years (range 26-40). Sixty-five percent had ER(+) tumors, 24% had negative axillary nodes with tumors >1 cm and high histological grade with lymphovascular invasion, while 76% had a mean of 3.6 positive axillary nodes (range 1-21). Serum estradiol was maintained at values <40 pg/ml in all of the patients. A statistically significant decrease in VEGF (P<0.0001) and T-regs (P<0.0001), with respect to baseline values, was observed after LH-RH administration. After a median follow-up of 110 months, the 10-year progression-free and overall survival rates were 86.1 and 89.7%, respectively. These data revealed that the administration of an LH-RH analogue to HREBC patients, followed by chemotherapy and hormonal therapy, decreased VEGF and T-regs and improved the expected clinical outcome.

    Purpose: To validate the prognostic value of interval to biochemical failure (IBF) in patients with high-risk prostate cancer (HiRPCa) treated with combined-modality radiation therapy (CMRT) with or without androgen deprivation therapy (ADT). Methods and Materials: We conducted a retrospective review of HiRPCa (prostate-specific antigen >20 ng/mL, Gleason score [GS] 8-10, or clinical T stage T3-T4) treated with either dose-escalated external beam radiation therapy (EBRT) or CMRT. Interval to biochemical failure was classified as ≤18 or >18 months from the end of all therapy to the date of biochemical failure (BF). Kaplan-Meier methods and Cox proportional hazards regression were used to evaluate the prognostic value of IBF ≤18 months for distant metastasis (DM) and prostate cancer-specific mortality (PCSM). Results: Of 958 patients with a median follow-up of 63.2 months, 175 patients experienced BF. In those with BF, there were no differences in pretreatment clinical characteristics between the EBRT and CMRT groups, except for a higher proportion of patients with GS 8-10 in the CMRT group (70% vs 52%, P=.02). Median IBF after all therapy was 24.0 months (interquartile range 9.6-46.0) in the EBRT group and 18.9 months (interquartile range 9.2-34.5) in the CMRT group (P=.055). On univariate analysis, IBF ≤18 months was associated with increased risk of DM and PCSM in the entire cohort and the individual EBRT and CMRT groups. On multivariate analysis, only GS 9-10 and IBF ≤18 months, but not the radiation therapy regimen or ADT use, predicted DM (hazard ratio [HR] 3.7, P<.01, 95% confidence interval [CI] 1.4-10.3 for GS 9-10; HR 3.9, P<.0001, 95% CI 2.4-6.5 for IBF ≤18 months) and PCSM (HR 14.8, P<.009, 95% CI 2.0-110 for GS 9-10; HR 4.4, P<.0001, 95% CI 2.4-8.1 for IBF ≤18 months). Conclusions: Short IBF was highly prognostic for higher DM and PCSM in patients with HiRPCa. The prognostic value of IBF for DM and PCSM was not affected by the radiation

    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

    Full Text Available Over the last fifteen years, attempts have been made to prospectively identify individuals in the prodromal phase of schizophrenia and other psychotic disorders. The ultra high risk approach, based on a combination of known trait and state risk factors, has been the main strategy used. The validation of the ultra high risk criteria allowed for predictive research in this population in an attempt to identify clinical, neurocognitive and neurobiological risk factors for psychosis onset. It also led to a series of intervention studies in this population, which have included the use of low dose antipsychotic medication, cognitive therapy, and omega-3 fatty acids. Although there is moderate evidence for the effectiveness of specific intervention strategies in this population, the most effective type and duration of intervention is yet to be determined. A current controversy in the field is whether to include an adaption of the ultra high risk criteria (the attenuated psychosis syndrome in the next version of the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition.Nos últimos quinze anos, foram feitas tentativas para identificar prospectivamente indivíduos na fase prodrômica de esquizofrenia e outros transtornos psicóticos.

  17. Risk Management in the Clinical Laboratory

    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.

    Background The N100 is a negative deflection in the surface EEG approximately 100ms after an auditory signal. It has been shown to be reduced in individuals with schizophrenia and those at clinical high risk (CHR). N100 blunting may index neural network dysfunction underlying psychotic symptoms. This phenomenon has received little attention in pediatric populations. Method This cross-sectional study compared the N100 response measured via the average EEG response at the left medial frontal position FC1 to 150 sinusoidal tones in participants ages 5 to 17 years with a CHR syndrome (n = 29), a psychotic disorder (n = 22), or healthy controls (n=17). Results Linear regression analyses that considered potential covariates (age, gender, handedness, family mental health history, medication usage) revealed decreasing N100 amplitude with increasing severity of psychotic symptomatology from healthy to CHR to psychotic level. Conclusions Longitudinal assessment of the N100 in CHR children who do and do not develop psychosis will inform whether it predicts transition to psychosis and if its response to treatment predicts symptom change.

    Full Text Available BACKGROUND: The identification of additional prognostic markers to improve risk stratification and to avoid overtreatment is one of the most urgent clinical needs in prostate cancer (PCa. MicroRNAs, being important regulators of gene expression, are promising biomarkers in various cancer entities, though the impact as prognostic predictors in PCa is poorly understood. The aim of this study was to identify specific miRNAs as potential prognostic markers in high-risk PCa and to validate their clinical impact. METHODOLOGY AND PRINCIPAL FINDINGS: We performed miRNA-microarray analysis in a high-risk PCa study group selected by their clinical outcome (clinical progression free survival (CPFS vs. clinical failure (CF. We identified seven candidate miRNAs (let-7a/b/c, miR-515-3p/5p, -181b, -146b, and -361 that showed differential expression between both groups. Further qRT-PCR analysis revealed down-regulation of members of the let-7 family in the majority of a large, well-characterized high-risk PCa cohort (n = 98. Expression of let-7a/b/and -c was correlated to clinical outcome parameters of this group. While let-7a showed no association or correlation with clinical relevant data, let-7b and let-7c were associated with CF in PCa patients and functioned partially as independent prognostic marker. Validation of the data using an independent high-risk study cohort revealed that let-7b, but not let-7c, has impact as an independent prognostic marker for BCR and CF. Furthermore, we identified HMGA1, a non-histone protein, as a new target of let-7b and found correlation of let-7b down-regulation with HMGA1 over-expression in primary PCa samples. CONCLUSION: Our findings define a distinct miRNA expression profile in PCa cases with early CF and identified let-7b as prognostic biomarker in high-risk PCa. This study highlights the importance of let-7b as tumor suppressor miRNA in high-risk PCa and presents a basis to improve individual therapy for high-risk

    Full Text Available Background: The default mode network (DMN is a set of brain regions typically activated at rest and suppressed during extrinsic cognition. Schizophrenia has been associated with deficient DMN suppression, though the extent to which DMN dysfunction predates psychosis onset is unclear. This study examined DMN suppression during working memory (WM performance in youth at clinical high-risk (CHR for psychosis, early schizophrenia patients (ESZ, and healthy controls (HC. We hypothesized that the DMN would show load-dependent suppression during WM retrieval in HC but not in ESZ, with CHR participants showing an intermediate pattern. Methods: FMRI data were collected from CHR (n=32, ESZ (n=22, and HC (n=54 participants, ages 12-30. DMN regions were defined via seed-based connectivity analysis of resting state fMRI data from an independent HC sample. Load-dependent deactivations of these DMN regions in response to WM probes were interrogated.Results: HC showed linear load-dependent increases in DMN deactivation. Significant Group-by-Load interactions were observed in DMN regions including medial prefrontal and lateral posterior parietal cortices. Group-by-Load effects in posterior DMN nodes resulted from less suppression at higher WM loads in ESZ relative to HC, with CHR differing from neither group. In medial prefrontal cortex, suppression of activity at higher WM loads was significantly diminished in both CHR and ESZ groups, relative to HC. In addition, investigation of dorsolateral prefrontal (DLPFC activations revealed that ESZ activated right DLPFC significantly more than HC, with CHR differing from neither group. Conclusion: While HC showed WM load-dependent modulation of DMN suppression, CHR individuals had deficient higher-load DMN suppression that was similar to, but less pronounced than, the distributed suppression deficits evident in ESZ patients. These results suggest that DMN dysregulation associated with schizophrenia predates psychosis

    Social cognition, the mental operations that underlie social interactions, is a major construct to investigate in schizophrenia. Impairments in social cognition are present before the onset of psychosis, and even in unaffected first-degree relatives, suggesting that social cognition may be a trait marker of the illness. In a large cohort of individuals at clinical high risk for psychosis (CHR) and healthy controls, three domains of social cognition (theory of mind, facial emotion recognition and social perception) were assessed to clarify which domains are impaired in this population. Six-hundred and seventy-five CHR individuals and 264 controls, who were part of the multi-site North American Prodromal Longitudinal Study, completed The Awareness of Social Inference Test, the Penn Emotion Recognition task, the Penn Emotion Differentiation task, and the Relationship Across Domains, measures of theory of mind, facial emotion recognition, and social perception, respectively. Social cognition was not related to positive and negative symptom severity, but was associated with age and IQ. CHR individuals demonstrated poorer performance on all measures of social cognition. However, after controlling for age and IQ, the group differences remained significant for measures of theory of mind and social perception, but not for facial emotion recognition. Theory of mind and social perception are impaired in individuals at CHR for psychosis. Age and IQ seem to play an important role in the arising of deficits in facial affect recognition. Future studies should examine the stability of social cognition deficits over time and their role, if any, in the development of psychosis.

    Goal-directed therapy (GDT) encompasses guidance of intravenous (IV) fluid and vasopressor/inotropic therapy by cardiac output or similar parameters to help in early recognition and management of high-risk cardiac surgical patients. With the aim of establishing the utility of perioperative GDT using robust clinical and biochemical outcomes, we conducted the present study. This multicenter randomized controlled study included 130 patients of either sex, with European system for cardiac operative risk evaluation ≥3 undergoing coronary artery bypass grafting on cardiopulmonary bypass. The patients were randomly divided into the control and GDT group. All the participants received standardized care; arterial pressure monitored through radial artery, central venous pressure (CVP) through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour, and frequent arterial blood gas (ABG) analysis. In addition, cardiac index (CI) monitoring using FloTrac™ and continuous central venous oxygen saturation (ScVO2) using PreSep™ were used in patients in the GDT group. Our aim was to maintain the CI at 2.5–4.2 L/min/m2, stroke volume index 30–65 ml/beat/m2, systemic vascular resistance index 1500–2500 dynes/s/cm5/m2, oxygen delivery index 450–600 ml/min/m2, continuous ScVO2 >70%, and stroke volume variation 30%, and urine output >1 ml/kg/h. The aims were achieved by altering the administration of IV fluids and doses of inotropes or vasodilators. The data of sixty patients in each group were analyzed in view of ten exclusions. The average duration of ventilation (19.89 ± 3.96 vs. 18.05 ± 4.53 h, P = 0.025), hospital stay (7.94 ± 1.64 vs. 7.17 ± 1.93 days, P = 0.025), and Intensive Care Unit (ICU) stay (3.74 ± 0.59 vs. 3.41 ± 0.75 days, P = 0.012) was significantly less in the GDT group, compared to the control group.

    2009-02-01

    Arterial hypertension is an important cardiovascular risk factor. The benefit drawn from decreasing and normalizing the blood pressure level is indisputable. The ACCOMPLISH study performed in patients older than 65 with systolic hypertension and a high cardiovascular risk pointed out the interest of well choosing the antihypertensive combination to reduce this risk beyond the decrease of blood pressure. The association of benazepril (an angiotensin converting enzyme inhibitor or ACEI) and amlodipine (a calcium antagonist) has shown significant early cardiovascular protection in such patients as compared to the classic association including the same ACEI and hydrochlorothiazide, in spite of the same target blood pressure reached. This important finding does not contest the interest of a well controlled blood pressure in hypertension, but probably will modify our first antihypertensive combination choice in the future in patients with such cardiovascular profile.

    To develop a multivariable survival model based on histopathological parameters that would provide the best possible estimate of the risk of death in cutaneous melanoma patients. Breslow thickness and Infiltrating Lymphocytes (BILL(CD8)) is based on two key parameters, namely Breslow thickness and tumor-infiltrating lymphocytes (TILs) shown to be the most important prognostic factors using logistic regression model. The next step was to apply a decision tree method to analyze the impact of the percentage of CD8+ lymphocytes on the risk of cancer death. A patient is given two points if Breslow thickness is >2 mm and one point if TILs are not found in the tumor. The probability of death over a 4-year follow-up is 75% if the patient's score is 3 points; in patients with 0 point score the risk of death is 0%. A significant positive impact of high percentage of CD8+ lymphocytes on the risk of death was shown in the subgroup of melanoma patients with Breslow thickness >2 mm where the risk of death is only 28%. In the case of low percentage of CD8+ lymphocytes in melanomas with Breslow thickness over 2 mm, the risk is as high as 67%. Breslow thickness and TILs, with the evaluation of the CD8+ lymphocytes, may be used for precise prognostic stratification of patients and may help intensify the follow-up, diagnose a relapse sooner and apply proper treatment.

    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.

    2011-06-01

    In the last years, German hospitals have implemented different measures to increase patient safety. Special importance has been attached to near miss reporting systems (critical incident reporting system, CIRS) as instruments for risk identification in health care, instruments that promise high potential for organisational learning. To gain insight into the current status of critical incident reporting systems and other instruments for clinical risk management, a survey among 341 hospitals was carried out in 2009. Questions covered a process of six steps: from risk strategy to methods for risk identification, to risk analysis and risk assessment, to risk controlling and risk monitoring. Structured telephone interviews were conducted with 341 German hospitals, featuring in their statutory quality reports certain predefined key terms that indicated the concluded or planned implementation of clinical risk management. The main objective of those interviews was to check the relation between status/organisation of self-reported risk management and both operator (private, public, NPO) and size of hospital. The implementation of near miss reporting systems (CIRS) in German hospitals has been constantly rising since 2004: in 2009, 54 % of the interviewed hospitals reported an implemented CIRS; of these, 72 % reported the system to be hospital-wide. An association between CIRS and private, public or NPO-operator could not be detected (Fisher p = 1.000); however, the degree of CIRS implementation was significantly increasing with the size of the hospital, i.e., the number of beds (Fisher p = 0.008): only 38 % of the hospitals with less than 100 beds reported CIRS implementation against 52 % of those between 100 to 500 beds, and 67 % of those with more than 500 beds. While 62 % of the hospitals interviewed reported the maintenance of a risk management committee, only 14 % reported the implementation of risk analysing techniques. As to clinical risk

    Full Text Available Recent research suggests that early intervention in psychosis might improve the chances of recovery and may even be able to prevent the onset of psychotic disorders. Clinical intervention in subjects at ultra high risk (UHR of psychosis can have three different objectives. The first aim is to improve the 'prodromal' symptoms and problems that subjects usually present with. The second is to reduce the risk of the subsequent onset of frank psychosis. The third objective is to minimize the delay before the initiation of antipsychotic treatment in the subgroup of UHR subjects that go on to develop a first episode of psychosis. Both pharmacological and psychological interventions appear to be effective in reducing the severity of presenting symptoms in UHR subjects. Clinical trials of the impact of these interventions on the risk of subsequent transition to psychosis have been positive, but have involved small samples, and thus the issue of whether the effects persist in the long term remains to be determined. The monitoring of UHR subjects for the first signs of frank psychosis is an effective means of reducing the delay between the onset of the first episode and the start of antipsychotic treatment. Follow-up studies are required to test whether the reduction in this delay leads to an improved long term outcome. To date, the majority of the interventions that have been used in UHR subjects, such as case management, antipsychotic medication, and cognitive behavior therapy have previously been employed in patients with established psychosis. However, it is possible that treatments that are not normally used in patients with psychotic disorders may prove effective when applied at this stage.Estudos recentes sugerem que a intervenção precoce na psicose poderia melhorar as chances de recuperação e inclusive evitar o início de transtornos psicóticos.

    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.

    The development of a new frontier for research and early intervention in psychotic disorders is highly dependent on the construction of synergistic clinical infrastructures. This has catalyzed great progress in the recognition, enhanced treatment, and study of first episode psychosis, and the task is even more challenging when the boundaries are extended to include the earliest clinical phase of illness, the prodromal or prepsychotic phase. This article describes the conceptual and practical building blocks for the construction of service models for intervention in the postonset clinical phase prior to the attainment of current diagnostic thresholds. This is best regarded as indicated prevention, a form of very early secondary prevention, which involves a blend of immediate clinical care combined with research-oriented preventive intervention. The experience of the Personal Assessment and Crisis Evaluation (PACE) Clinic in Melbourne across several stages of growth is described and contrasted with that of several emerging centers in Europe and North America. The progress to date, the lessons learned, and the unresolved challenges and opportunities are detailed. It is concluded that service models can be developed that are acceptable and helpful to young people and their families, and that create a unique environment for the study of the transition to frank psychotic disorder. The ultimate clinical utility and general safety of this approach and the range of effective treatments remain unclear, and will be determined by more extensive research. Such research must be conducted in a logical and rigorous manner with the best designs possible, sensitive to input from consumers and caregivers and to ethical considerations.

    Background For patients with moderate to high-risk acute coronary syndromes(ACS)who undergo early,invasive treatment strategies,current guidelines recommend the usage of glycoprotein(GP)lib/Illa inhibitors as an upstream treatment for a coronary care unit or as an downstream provisional treatment for selected patients who are undergoing percutaneous coronary intervention(PCI).The relative advantage of either strategy is unknown.The purpose of this study was to evaluate the effects of upstream tirofiban versus the effects of downstream tirofiban on myocardial damage and 180-day major adverse cardiovascular events(MACE)after PCI in high-risk non-ST-segment elevation ACS (NSTE-ACS)undergoing PCI.Methods From July 2006 to July 2007,160 high-risk NSTE-ACS undergoing PCI were randomized to receive upstream (within 4-6 hours before coronary angiography)tirofiban or downstream(the guidewire crossing the lesion)tirofiban,to evaluate the extent of myocardial damage after PCI by quantitatively and qualitatively analyzing the value of cardiac troponin I(cTnl)as well as MB isoenzyme of creatine kinase(CK-MB)before and after PCI.The incidences of 24-hour,3-day,7-day,30-day and 180-day MACE after PCI were followed up and the rates of bleeding complications and thrombocytopenia during tirofiban administration were recorded.Results The peak release and cumulative release of cTnl levels within 48 hours after PCI were significantly lower with upstream tirefiban than downstream tirofiban(0.45 vs 0.63 and 0.32 vs 0.43,respectively;P<0.05).Post-procedural cTnl elevation within 48 hours was significantly less frequent among patients who received the upstream tirofiban than those who received the downstream tirefiban(66.3%vs 87.5%,P<0.05).The peak and cumulative release of CK-MB levels as well as post-procedural CK-MB elevation within 48 hours after PCI were not significantly different between the two groups (16 vs 14,5 vs 3 and 26.3%vs 36.3%,respectively;P>0.05).The incidences of

    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.

This study sought to evaluate the clinical outcomes of triple antiplatelet treatment (TAPT) (cilostazol added to aspirin plus clopidogrel) in these patients. Methods The PubMed, EMBASE, MEDLINE, and other Internet sources were searched for relevant articles. The primary end point was major adverse cardiac events (MACE), including all-cause mortality, myocardial infarction, and target vessel revascularization. The incidence of definite/probable stent thrombosis and bleeding were analyzed as the safety end points. Results Eleven clinical trials involving 9,553 patients were analyzed. The risk of MACE was significantly decreased following TAPT after stent implantation in the ACS subgroup (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.61–0.85; P<0.001), which might mainly result from the lower risk of all-cause mortality in this subset (OR: 0.62; 95% CI: 0.48–0.80; P<0.001). The risk of bleeding was not increased with respect to TAPT. Conclusion TAPT after stent implantation was associated with feasible benefits on reducing the risk of MACE, especially on reducing the incidence of all-cause mortality among patients suffering from ACS, without higher incidence of bleeding. Larger and more powerful randomized trials are still warranted to prove the superiority of TAPT for such patients. PMID:27799743

    Objective:To investigate the influence of early intervention on the movement and intelligence development of high-risk infants. Methods:113 cases of high-risk infants were randomly divided into intervention group (58 cases) and control group (55 cases), both of the groups accepted con-ventional parental guidance, while the intervention group combined with implementation of early intervention (infantile massage, family guidance, re-habilitation training), compared the Gesell development scores and prognosis of the two groups of high-risk infants. Results:The Gesell scores index-es of adaptability, gross motor, fine motion, language, personal social of intervention group were all significantly higher than those of control group (P<0.05);the cerebral palsy occurrence of intervention group was significantly lower than that of control group (P<0.05). Conclusion:Early interven-tion which can effectively reduce the occurrence of neurological sequelae and improve the quality of life of the infants and their family has a signifi-cant promoting effect on the movement and intelligence development of high-risk infants.%目的:探讨早期干预措施对高危儿运动、智能发育的影响。方法:将113例高危儿随机分为干预组(58例)和对照组(55例),均给予常规育儿指导,干预组则配合实施早期干预(小儿推拿、家庭指导、康复训练),比较两组高危儿Gesell发育量表评分及预后。结果:干预组适应性、大运动、精细运动、语言、个人社交等Gesell各指标评分均显著高于对照组(P<0.05);干预组脑性瘫痪发生率显著低于对照组(P<0.05)。结论:早期干预对高危儿的运动及智能发育有显著的促进作用,并可有效降低神经系统后遗症的发生率,提高患儿及家庭的生活质量。

    Full Text Available Studies regarding the effects of high protein (HP diets on cardiovascular (CVD risk factors have reported contradictory results. We aimed to determine the effects of an HP diet on CVD risk factors and high-sensitivity C-reactive protein (hs-CRP among overweight and obese women. In this randomized controlled trial, we recruited 60 overweight and obese women, aged 20–65, into an HP or energy-restricted control diet for three months (protein, carbohydrate, and fat: 25%, 45%, and 30% versus 15%, 55%, and 30%, resp.. Total protein was divided between animal and plant sources in a 1 : 1 ratio, and animal sources were distributed equally between meats and dairy products. Fasting blood samples, hs-CRP, lipid profile, systolic and diastolic blood pressure, and anthropometric measurements were assessed using standard guidelines. Percent change was significantly different between the two diet groups for weight (standard protein (SP: −3.90 ± 0.26 versus HP: −6.10 ± 0.34%; , resp. and waist circumference (SP: −3.03 ± 0.21 versus HP: −5.06 ± 0.28%; , resp.. Percent change of fasting blood glucose (FBG substantially decreased in the control group compared to the HP group (−9.13 ± 0.67 versus −4.93 ± 1.4%; P = 0.01, resp.. Total cholesterol, systolic blood pressure (SBP, and diastolic blood pressure (DBP decreased both in the HP and in the control diet groups (P = 0.06, P = 0.07, and P = 0.09, resp.; however, the results were marginally significant. Serum levels of hs-CRP were reduced both in the control (−0.08 ± 0.11%, P = 0.06 and in the high protein groups (−0.04 ± 0.09%, P = 0.06. The energy-restricted HP diet resulted in more beneficial effects on weight loss and reduction of waist circumference. CVD risk factors may improve with HP diets among overweight and obese women. When using isoenergetic weight loss diets, total cholesterol, hs-CRP, and SBP were marginally significantly reduced, independent of dietary protein content

    Full Text Available Abstract Background Peripheral arterial disease (PAD is a common disease associated with a considerably increased risk of future cardiovascular events and most of these patients will die from coronary artery disease (CAD. Screening for silent CAD has become an option with recent non-invasive developments in CT (computed tomography-angiography and MR (magnetic resonance stress testing. Screening in combination with more aggressive treatment may improve prognosis. Therefore we propose to study whether a cardiac imaging algorithm, using non-invasive imaging techniques followed by treatment will reduce the risk of cardiovascular disease in PAD patients free from cardiac symptoms. Design The GROUND study is designed as a prospective, multi-center, randomized clinical trial. Patients with peripheral arterial disease, but without symptomatic cardiac disease will be asked to participate. All patients receive a proper risk factor management before randomization. Half of the recruited patients will enter the 'control group' and only undergo CT calcium scoring. The other half of the recruited patients (index group will undergo the non invasive cardiac imaging algorithm followed by evidence-based treatment. First, patients are submitted to CT calcium scoring and CT angiography. Patients with a left main (or equivalent coronary artery stenosis of > 50% on CT will be referred to a cardiologist without further imaging. All other patients in this group will undergo dobutamine stress magnetic resonance (DSMR testing. Patients with a DSMR positive for ischemia will also be referred to a cardiologist. These patients are candidates for conventional coronary angiography and cardiac interventions (coronary artery bypass grafting (CABG or percutaneous cardiac interventions (PCI, if indicated. All participants of the trial will enter a 5 year follow up period for the occurrence of cardiovascular events. Sequential interim analysis will take place. Based on sample size

    Diabetes mellitus is recognized an independent risk factor for coronary artery disease (CAD) and mortality. Clinical trials have shown that statins significantly reduce cardiovascular events in diabetic patients. However, residual cardiovascular risk persists despite the achievement of target low-density lipoprotein cholesterol (LDL-C) levels with statin. High-density lipoprotein cholesterol (HDL-C) is an established coronary risk factor that is independent of LDL-C levels. We evaluated the impact of HDL-C on long-term mortality in diabetic patients with stable CAD who achieved optimal LDL-C. We enrolled 438 consecutive diabetic patients who were scheduled for percutaneous coronary intervention between 2004 and 2007 at our institution. We identified 165 patients who achieved target LDL-C diabetic patients with low-HDL-C who achieved optimal LDL-C (6.9 vs 17.9 %, log-rank P = 0.030). Multivariate Cox regression analysis showed that HDL-C is significantly associated with clinical outcomes (adjusted hazard ratio for MACE 1.33, 95 % confidence interval 1.01-1.75, P = 0.042). Low HDL-C is a residual risk factor that is significantly associated with long-term clinical outcomes among diabetic patients with stable CAD who achieve optimal LDL-C levels.

    Purpose: The aim of the study was to improve computed tomography (CT)-based high-risk clinical target volume (HR CTV) delineation protocols for cervix cancer patients, in settings without any access to magnetic resonance imaging (MRI) at the time of brachytherapy. Therefore the value of a systematic integration of comprehensive three-dimensional (3D) documentation of repetitive gynecological examination for CT-based HR CTV delineation protocols, in addition to information from FIGO staging, was investigated. In addition to a comparison between reference MRI contours and two different CT-based contouring methods (using complementary information from FIGO staging with or without additional 3D clinical drawings), the use of standardized uterine heights was also investigated. Material and methods: Thirty-five cervix cancer patients with CT- and MR-images and 3D clinical drawings at time of diagnosis and brachytherapy were included. HR CTV{sub stage} was based on CT information and FIGO stage. HR CTV{sub stage} {sub +3Dclin} was contoured on CT using FIGO stage and 3D clinical drawing. Standardized HR CTV heights were: 1/1, 2/3 and 1/2 of uterine height. MRI-based HR CTV was delineated independently. Resulting widths, thicknesses, heights, and volumes of HR CTV{sub stage}, HR CTV{sub stage+3Dclin} and MRI-based HR CTV contours were compared. Results: The overall normalized volume ratios (mean{+-}SD of CT/MRI{sub ref} volume) of HR CTV{sub stage} and HR{sub stage+3Dclin} were 2.6 ({+-}0.6) and 2.1 ({+-}0.4) for 1/1 and 2.3 ({+-}0.5) and 1.8 ({+-}0.4), for 2/3, and 1.9 ({+-}0.5) and 1.5 ({+-}0.3), for 1/2 of uterine height. The mean normalized widths were 1.5{+-}0.2 and 1.2{+-}0.2 for HR CTV{sub stage} and HR CTV{sub stage+3Dclin}, respectively (p < 0.05). The mean normalized heights for HR CTV{sub stage} and HR CTV{sub stage+3Dclin} were both 1.7{+-}0.4 for 1/1 (p < 0.05.), 1.3{+-}0.3 for 2/3 (p < 0.05) and 1.1{+-}0.3 for 1/2 of uterine height.

    In patients with type 2 diabetes mellitus (T2DM), hypertension and microalbuminuria are predictive markers for increased renal and cardiovascular risk. This post hoc analysis of data from a global development program aimed to evaluate the efficacy and safety of linagliptin in a population with joint prevalence of these two vascular risk factors. Data for patients with baseline microalbuminuria (urine albumin-to-creatinine ratio 30-300 mg/g) and hypertension (systolic blood pressure ≥ 140 mm Hg and/or diastolic blood pressure ≥ 90 mm Hg and/or a history of hypertension; and/or an antihypertensive treatment at baseline) who participated in any of six randomized, placebo-controlled, phase III trials were analyzed. Participants received linagliptin 5 mg daily (alone or in combination with other oral antidiabetic drugs) or placebo for 18 to 24 weeks. Of 3,119 patients, 512 had both microalbuminuria and hypertension (linagliptin, 366; placebo, 146). Baseline mean (SD) HbA1c was 8.3 (0.9)% and 8.4 (0.9)%; median (range) urine albumin-to-creatinine ratio was 60 (30-292) mg/g and 64 (30-298) mg/g; mean (SD) systolic blood pressure was 138 (15) mm Hg and 135 (16) mm Hg; and mean (SD) diastolic blood pressure was 81 (10) mm Hg and 81 (10) mm Hg, for linagliptin and placebo, respectively. Placebo-corrected mean change in HbA1c from baseline to week 18 and week 24 was -0.57% (95% CI: -0.75, -0.39; P blood pressure, cholesterol and triglyceride levels were similar between linagliptin and placebo. In T2DM patients with the two common vascular risk factors of hypertension and microalbuminuria, linagliptin achieved significant improvements in glycemic control. In this vulnerable patient population at high risk for micro- and macrovascular complications, linagliptin was well tolerated.

    Individuals with hereditary cancer syndromes form a minor but clinically important subgroup of oncology patients, comprising several thousand cases in the Czech Republic annually. In these patients, the identification of pathogenic mutations in cancer susceptibility genes has an important predictive and, in some cases, prognostic value. It also enables rational preventive strategies in asymptomatic carriers from affected families. More than 150 cancer susceptibility genes have been described so far; however, mutations in most of them are very rare, occurring with substantial population variability, and hence their clinical interpretation is very complicated. Diagnostics of mutations in cancer susceptibility genes have benefited from the broad availability of next-generation sequencing analyses using targeted gene panels. In order to rationalize the diagnostics of hereditary cancer syndromes in the Czech Republic, we have prepared the sequence capture panel "CZECANCA", targeting 219 cancer susceptibility genes. Besides more than 50 clinically important high- and moderate-penetrance susceptibility genes, the panel also targets less common candidate genes with uncertain clinical relevance. Alongside the panel design, we have optimized the analytical and bioinformatics pipeline, which will facilitate establishing a collective nationwide database of genotypes and clinical data from the analyzed individuals. The key objective of this project is to provide diagnostic laboratories in the Czech Republic with a reliable procedure and collective database improving the clinical utility of next-generation sequencing analyses in high-risk patients, which would help improve the interpretation of rare or population-specific variants in cancer susceptibility genes.

    Aggressive non-Hodgkin's lymphomas (NHL) in patients under the age of 60 have a very poor prognosis when the international prognostic index (IPI) is high, with an age-adjusted (Aa)-IPI score at 3. In such patients, conventional chemotherapy results in a low complete response (CR) rate of 46%, a five-year survival and disease-free survival (DFS) of 32% and 58%, respectively. For this report we have analyzed whether front-line high-dose chemotherapy could influence the outcome of this group of patients. From 1992 onwards we conducted two pilot clinical trials of intensive sequential chemotherapy (ISC) with growth factors and blood stem cell support as initial treatment in 62 poor-risk patients with aggressive NHL. Of these patients, 33 were considered to be a high-risk group based on the Aa-IPI. The median age was 42 years (range 21-60). The treatment was completed in 88% of patients, 86% receiving greater than 75% or more of the projected dose-intensity. Twenty patients (61%) achieved a CR. At a median follow-up of 48 months (range 26-86), the estimated five-year survival and DFS was 51% (95% confidence interval (CI): 34%-68%) and 70% (95% CI: 50%-90%), respectively. These results suggest that primary treatment using high-dose therapy supported by both growth factors and peripheral blood stem cells can cure up to 50% of high-risk patients with malignant lymphomas.

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

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.

    Accurate and early identification of high-risk surgical patients allows for targeted use of perioperative monitoring and interventions that may improve their outcomes. This review summarizes current evidence on how information from the preoperative, operative, and immediate postoperative periods can help identify such individuals. Simple risk indices, such as the Revised Cardiac Risk Index or American Society of Anesthesiologists Physical Status scale, and online calculators allow risk to be estimated with moderate accuracy using readily available preoperative clinical information. Both specific specialized tests (i.e., cardiopulmonary exercise testing and cardiac stress testing) and promising novel biomarkers (i.e., troponins and natriuretic peptides) can help refine these risk estimates before surgery. Estimates of perioperative risk can be further informed by information acquired during the operative and immediate postoperative periods, such as risk indices (i.e., surgical Apgar score), individual risk factors (i.e., intraoperative hypotension), or postoperative biomarkers (i.e., troponins and natriuretic peptides). Preoperative clinical risk indices and risk calculators estimate surgical risk with moderate accuracy. Although novel biomarkers, specialized preoperative testing, and immediate postoperative risk indices show promise as methods to refine these risk estimates, more research is needed on how best to integrate risk information from these different sources.

    Recent studies have suggested an important role for Broca's region and its right hemisphere counterpart in the pathophysiology of schizophrenia, owing to its roles in language and interpersonal information processing. Broca's region consists of the pars opercularis (PO) and the pars triangularis (PT). Neuroimaging studies have suggested that they have differential functional roles in healthy individuals and contribute differentially to the pathogenesis of schizophrenic symptoms. However, volume changes in these regions in subjects with ultra-high risk for psychosis (UHR) or first-episode schizophrenia (FES) have not been clarified. In the present 3 Tesla magnetic resonance imaging study, we separately measured the gray matter volumes of the PO and PT using a reliable manual-tracing volumetry in 80 participants (20 with UHR, 20 with FES, and 40 matched controls). The controls constituted two groups: the first group was matched for age, sex, parental socioeconomic background, and intelligence quotient to UHR (n=20); the second was matched for those to FES (n=20). Compared with matched controls, the volume of the bilateral PT, but not that of the PO, was significantly reduced in the subjects with UHR and FES. The reduced right PT volume, which showed the largest effect size among regions-of-interest in the both UHR and FES groups, correlated with the severity of the positive symptoms also in the both groups. These results suggest that localized gray matter volume reductions of the bilateral PT represent a vulnerability to schizophrenia in contrast to the PO volume, which was previously found to be reduced in patients with chronic schizophrenia. The right PT might preferentially contribute to the pathogenesis of psychotic symptoms.

    Full Text Available Abstract Background To evaluate the metabolic effects of two weight loss diets differing in macronutrient composition on features of dyslipidemia and post-prandial insulin (INS response to a meal challenge in overweight/obese individuals. Methods This study was a parallel-arm randomized 4 mo weight loss trial. Adults (n = 50, 47 ± 7 y matched on BMI (33.6 ± 0.6 kg/m2, P = 0.79 consumed energy restricted diets (deficit ~500 kcal/d: PRO (1.6 g.kg-1.d-1 protein and -1.d-1 protein and > 220 g/d carbohydrate for 4 mos. Meal challenges of respective diets were utilized for determination of blood lipids and post-prandial INS and glucose response at the beginning and end of the study. Results There was a trend for PRO to lose more weight (-9.1% vs. -7.3%, P = 0.07 with a significant reduction in percent fat mass compared to CHO (-8.7% vs. -5.7%; P = 0.03. PRO also favored reductions in triacylglycerol (-34% vs. -14%; P P = 0.05; however, CHO favored reduction in LDL-C (-7% vs. +2.5%; P P P Conclusion A weight loss diet with moderate carbohydrate, moderate protein results in more favorable changes in body composition, dyslipidemia, and post-prandial INS response compared to a high carbohydrate, low protein diet suggesting an additional benefit beyond weight management to include augmented risk reduction for metabolic disease.

    Objective: To evaluate the effects of preoperative inspiratory muscle training (IMT) on the incidence of atelectasis in patients at high risk of postoperative pulmonary complications scheduled for elective total hip replacement surgery under general anesthesia. Methods: Thirty two high-risk paticnts undergoing elective total hip replacement surgery under general anesthesia were chosen from Nanjing Medical University, Affiliated Nanjing First Hospital. In this single-blind randomized controlled clinical trial, patients were randomly assigned to receive preoperative inspiratory muscle training or conventional treatment (CT). The major effectiveness outcome variables were atelectasis and duration of postoperative hospitalization. Results: Both groups were comparable prior to surgery. Seven patients in the CT group and 3 in the IMT group developed atelectasis (P = 0.25). Median duration of postoperative hospitalization was 13 days (range, 10~17 days) in the IMT group versus 16 days (range, 11~23 days) in the CT group (Mann-Whitney U statistics, Z =-2.22, P = 0.03). Mean postoperative inspiratory pressure was 5% higher in the IMT group. Conclusion: Preoperative intensive inspiratory muscle training appears to reduce the incidence of atelectasis and duration of postoperative hospitalization in patients at high risk of developing postoperative pulmonary complications who were scheduled for elective total hip replacement surgery under general anesthesia.

    The longer psychotic disorders are untreated the worse their prognosis. Increasing the awareness of early psychosis by professionals who come into regular contact with young people is one strategy that could reduce treatment delay. As teachers engage with students on a daily basis, their role could be exploited to increase awareness of the early signs of psychosis. This study employed the Theory of Planned Behaviour (TPB) to identify and measure factors that influence identification of students at high-risk (HR) of developing psychosis in 16+ educational institutions. An elicitation phase revealed beliefs underlying teachers' motivations to detect HR students and informed the construction of a preliminary 114-item questionnaire incorporating all constructs outlined in the TPB. To define the determinants of teachers' intention to identify HR students, 75 teachers from secondary and further education institutions in 12 counties surrounding Cambridgeshire completed the questionnaire. A psychometric model of item response theory was used to identify redundant items and produce a reduced questionnaire that would be acceptable to teachers. The final instrument comprised 73 items and showed acceptable reliability (α  = 0.69-0.81) for all direct measures. Teacher's confidence and control over identification of HR students was low. Although identification of HR students was considered worthwhile, teachers believed that their peers, students and particularly their managers might not approve. Path analysis revealed that direct measures of attitude and PBC significantly predicted intention, but subjective norm did not. PBC was the strongest predictor of intention. Collectively, the direct measures explained 37 % of the variance of intention to identify HR for psychosis. This research demonstrated how the TPB can be used to identify and measure factors that influence identification of students at HR of developing psychosis in 16+ educational institutions and confirmed the

    Although most children with acute lymphoblastic leukemia (ALL) are cured, certain subsets have a high risk of relapse. Relapse risk can be predicted by early response to therapy, clinical and pharmacogenetic features of the host, and genetic characteristics of leukemic cells. Though early treatment response can be assessed by the peripheral blast cell count after 1 week of single-agent glucocorticoid treatment or percent of bone marrow blasts by morphology after 1 or 2 weeks of multiagent induction treatment, determination of minimal residual disease by polymerase chain reaction (PCR) or flow cytometry after 2 to 6 weeks of induction is the most precise and useful measure. Augmented therapy has improved outcome for the poor responders to initial treatment. Infants with mixed-lineage leukemia (MLL)–rearranged ALL comprise a very poor-risk group wherein further intensification of chemotherapy causes significant toxicity. Hybrid protocols incorporating drugs effective for acute myeloid leukemia could improve survival, a strategy being tested in international trials. Studies on the biology of MLL-induced leukemogenesis have prompted the development of novel targeted agents, currently under evaluation in clinical trials. Short-term outcomes of patients with Philadelphia chromosome (Ph)–positive ALL have improved significantly by adding tyrosine kinase inhibitors to standard chemotherapy regimens. New agents and methods to overcome resistance are under investigation, and allogeneic stem cell transplantation is recommended for certain subsets of patients, for example those with Ph+ and T-cell ALL with poor early response. Genome-wide interrogation of leukemic cell genetic abnormalities and germline genetic variations promise to identify new molecular targets for therapy. PMID:19778845

    After prolonged mechanical ventilation patients may experience the 'post intensive care syndrome' (PICS) and may be candidates for post-discharge follow-up clinics. We aimed to ascertain the incidence and severity of PICS symptoms in patients surviving prolonged mechanical ventilation and to describe their views regarding follow-up clinics. In a teaching hospital, we conducted a cohort study of all adult patients discharged alive after ventilation in ICU for ≥7 days during 2013. We administered the EuroQol-5D (EQ-5D) and Hospital Anxiety and Depression Scale (HADS) via telephone interview and asked patients their views about the possible utility of a follow-up clinic. We studied 48 patients. At follow-up (average 19.5 months), seven (15%) patients had died and 14 (29%) did not participate (eight declined; two were non-English speakers; four were non-contactable). Among the 27 responders, 16 (59%) reported at least moderate problems in ≥1 EQ-5D dimension; 10 (37%) in ≥2 dimensions, and 8 (30%) in ≥3 dimensions. Moreover, 10 (37%) patients reported marked psychological symptoms; six (22%) scored borderline or abnormal on the HADS for both anxiety and depression; and four (15%) scored borderline or abnormal for one component. Finally, 21/26 (81%) patients stated that an ICU follow-up clinic would have been beneficial. At long-term follow-up, the majority of survivors of prolonged mechanical ventilation reported impaired quality of life and significant psychological symptoms. Most believed that a follow-up clinic would have been beneficial.

    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.

    A recent large-scale randomized controlled trial (RCT) demonstrated that rectal indomethacin administration is effective in addition to pancreatic stent placement (PSP) for preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in high-risk cases. We performed a post hoc analysis of this RCT to explore whether rectal indomethacin can replace PSP in the prevention of PEP and to estimate the potential cost savings of such an approach. We retrospectively classified RCT subjects into four prevention groups: (1) no prophylaxis, (2) PSP alone, (3) rectal indomethacin alone, and (4) the combination of PSP and indomethacin. Multivariable logistic regression was used to adjust for imbalances in the prevalence of risk factors for PEP between the groups. Based on these adjusted PEP rates, we conducted an economic analysis comparing the costs associated with PEP prevention strategies employing rectal indomethacin alone, PSP alone, or the combination of both. After adjusting for risk using two different logistic regression models, rectal indomethacin alone appeared to be more effective for preventing PEP than no prophylaxis, PSP alone, and the combination of indomethacin and PSP. Economic analysis revealed that indomethacin alone was a cost-saving strategy in 96% of Monte Carlo trials. A prevention strategy employing rectal indomethacin alone could save approximately $150 million annually in the United States compared with a strategy of PSP alone, and $85 million compared with a strategy of indomethacin and PSP. This hypothesis-generating study suggests that prophylactic rectal indomethacin could replace PSP in patients undergoing high-risk ERCP, potentially improving clinical outcomes and reducing healthcare costs. A RCT comparing rectal indomethacin alone vs. indomethacin plus PSP is needed.

    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.

    The European Association of Urology (EAU) guidelines advise an elective bilateral lymphadenectomy in clinically node-negative (cN0) patients with high-risk penile carcinoma (≥pT2, G3, or lymphovascular invasion [LVI]). Our aim was to assess prognostic factors for occult metastasis and to determine whether current EAU guidelines accurately stratify patients at high risk. Data of 342 cN0 patients with histologically proven invasive penile squamous cell carcinoma who had undergone the current dynamic sentinel node biopsy (DSNB) protocol were analysed. A complete ipsilateral inguinal lymphadenectomy was only done if the sentinel node was tumour positive. The presence of occult metastasis was established by preoperative ultrasound and tumour-positive fine-needle aspiration cytology, tumour-positive sentinel nodes, and groin metastases during follow-up after a negative DSNB procedure. Median follow-up was 31 mo. Sixty-eight of 342 patients (20%) and 87 of 684 groins (13%) had occult nodal involvement including 6 patients (2%) with a groin metastasis after negative DSNB. Corpus spongiosum invasion, corpus cavernosum invasion, histologic grade, and LVI were each significant prognosticators for occult metastasis on univariate analysis. On multivariate analysis, grade (odds ratio [OR]: 3.3 for intermediate and 4.9 for poor, respectively) and LVI (OR: 2.2) remained predictive factors. In total, 245 patients (72%) were classified high risk according to EAU guidelines. Among them, the incidence of occult metastasis was 23% (57 of 245). A potential limitation of this study is the lack of external review. Histologic grade and LVI are independent prognostic factors for occult metastasis in penile carcinoma. Although both predictors are incorporated into the current EAU guidelines, the stratification of patients needing a lymph node dissection is inaccurate. Approximately 77% of high-risk patients (188 of 245) would have had a negative bilateral inguinal lymphadenectomy. For the

    Full Text Available High-dose-rate brachytherapy (HDR-BT with external beam radiation therapy (EBRT is a common treatment option for locally advanced prostate cancer (PCa. Seventy-nine male patients (median age 71 years, range 50 to 79 with high-risk PCa underwent HDR-BT following EBRT between December 2009 and January 2016 with a median follow-up of 21 months. HDR-BT was administered in two treatment sessions (one week interval with 9 Gy per fraction using a planning system and the Ir192 treatment unit GammaMed Plus iX. EBRT was performed with CT-based 3D-conformal treatment planning with a total dose administration of 50.4 Gy with 1.8 Gy per fraction and five fractions per week. Follow-up for all patients was organized one, three, and five years after radiation therapy to evaluate early and late toxicity side effects, metastases, local recurrence, and prostate-specific antigen (PSA value measured in ng/mL. The evaluated data included age, PSA at time of diagnosis, PSA density, BMI (body mass index, Gleason score, D’Amico risk classification for PCa, digital rectal examination (DRE, PSA value after one/three/five year(s follow-up (FU, time of follow-up, TNM classification, prostate volume, and early toxicity rates. Early toxicity rates were 8.86% for gastrointestinal, and 6.33% for genitourinary side effects. Of all treated patients, 84.81% had no side effects. All reported complications in early toxicity were grade 1. PSA density at time of diagnosis (p = 0.009, PSA on date of first HDR-BT (p = 0.033, and PSA on date of first follow-up after one year (p = 0.025 have statistical significance on a higher risk to get a local recurrence during follow-up. HDR-BT in combination with additional EBRT in the presented design for high-risk PCa results in high biochemical control rates with minimal side-effects. PSA is a negative predictive biomarker for local recurrence during follow-up. A longer follow-up is needed to assess long-term outcome and toxicities.

    Background E75 (nelipepimut-S) is a human leukocyte antigen (HLA)-A2/A3-restricted immunogenic peptide derived from the HER2 protein. We have conducted phase I/II clinical trials vaccinating breast cancer patients with nelipepimut-S and granulocyte–macrophage colony-stimulating factor (GM-CSF) in the adjuvant setting to prevent disease recurrence. All patients have completed 60 months follow-up, and here, we report the final analyses. Patients and methods The studies were conducted as dose escalation/schedule optimization trials enrolling node-positive and high-risk node-negative patients with tumors expressing any degree of HER2 (immunohistochemistry 1–3+). HLA-A2/3+ patients were vaccinated; others were followed prospectively as controls. Local and systemic toxicity was monitored. Clinical recurrences were documented, and disease-free survival (DFS) was analyzed by Kaplan–Meier curves; groups were compared using log-rank tests. Results Of 195 enrolled patients, 187 were assessable: 108 (57.8%) in the vaccinated group (VG) and 79 (42.2%) in the control group (CG). The groups were well matched for clinicopathologic characteristics. Toxicities were minimal. Five-year DFS was 89.7% in the VG versus 80.2% in the CG (P = 0.08). Due to trial design, 65% of patients received less than the optimal vaccine dose. Five-year DFS was 94.6% in optimally dosed patients (P = 0.05 versus the CG) and 87.1% in suboptimally dosed patients. A voluntary booster program was initiated, and among the 21 patients that were optimally boosted, there was only one recurrence (DFS = 95.2%). Conclusion The E75 vaccine is safe and appears to have clinical efficacy. A phase III trial evaluating the optimal dose and including booster inoculations has been initiated.

    Objectives We aim to present new knowledge about different perspectives of health care professionals’ risk perceptions and clinical decision making. Furthermore, we intend to discuss differences between professional and personal risk perceptions and the impact on decisions in terms of both short...... and long-term outcomes. Background Insight into healthcare professionals’ perception of risk is a cornerstone for understanding their strategies for practising preventive care. The way people perceive risk can be seen as part of a general personality trait influenced by a mixture of individual...... considerations and the specific context. Most research has been focused on understanding of the concepts of risk. However healthcare professionals’ risk perception and personal attitudes also affect their clinical decision-making and risk communication. The differences between health care professionals’ personal...

    This study was aimed to observe the clinical efficacy and adverse effects of decitabine plus improved CAG chemotherapy and haploid-identical donor peripheral lymphocyte infusion regimen on elderly patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Five elderly patients with MDS and AML were treated with decitabine plus improved CAG chemotherapy and donor peripheral lymphocyte infusion regimen. Examinations on liver and renal function, electrocardiogram and bone marrow analysis were performed before and after treatment, and adverse effects were observed. The results indicated that after a course of treatment by decitabine plus improved CAG chemotherapy and haplo-identical donor peripheral lymphocyte infusion regimen, the total effective rate was 100%, and 4 patients (80%) achieved complete remission, 1 patient achieved partial remission. The dominant clinical adverse effect was bone marrow depression, the median time of neutrophil>0.5×10(9)/L and platelet>20×10(9)/L was 15 d and 16 d respectively for patients without previous MDS. It is concluded that decitabine plus improved CAG chemotherapy and haploid-identical donor peripheral lymphocyte infusion regimen may be effective with less adverse effects for elderly primary AML and high risk MDS patients, it is a promising therapeutic methods and worthy to deeply study.

    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.

    After treatment with local excision for TNM stage I low rectal cancer, the risk of local recurrence is not only high for T2 lesions but also for T1 lesions with features of massive invasion to the submucosal layer and/or lymphovascular invasion. The purpose of this study was to determine the efficacy of chemoradiotherapy combined with local excision in the treatment of T1 to T2 low rectal cancer. We conducted a prospective, single-arm, phase II trial. This was a multicenter study. From April 2003 to October 2010, 57 patients were treated with local excision after additional external beam irradiation (45 Gy) plus continuous 5-week intravenous injection of 5-fluorouracil (250 mg/m per day) at 10 domestic hospitals. Fifty-three patients had clinical T1N0 lesions, and 4 had T2N0 lesions in the low rectum, located below the peritoneal reflection. The primary end point was disease-free survival at 5 years. The completion rate for full-dose chemoradiotherapy was 86% (49/57). Serious, nontransient treatment-related complications were not reported. With a median follow-up of 7.3 years after local excision, the 5-year disease-free survival rate was 94% for the 53 patients with T1 lesions and 75% for the 4 patients with T2 lesions. There were 2 local recurrences during the entire observation period. Anal function after local excision and chemoradiation were kept at almost the same levels as observed before treatment. The study was limited by the small number of registered T2 rectal cancers, retrospective evaluations of quality of life, and the exclusion of poorly differentiated adenocarcinoma (a high-risk feature of T1 lesions). The addition of chemoradiotherapy to local excision of T1 rectal adenocarcinomas with poor prognostic features including deep submucosal invasion and lymphovascular invasion could improve on less favorable historic oncologic outcomes of local excision alone in this high-risk group for lymph node metastasis.

    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.

    This study aimed to determine the value of using a mix of clinical pharmacy data and routine hospital admission spell data in the development of predictive algorithms. Exploration of risk factors in hospitalized patients, together with the targeting strategies devised, will enable the prioritization of clinical pharmacy services to optimize patient outcomes. Predictive algorithms were developed using a number of detailed steps using a 75% sample of integrated medicines management (IMM) patients, and validated using the remaining 25%. IMM patients receive targeted clinical pharmacy input throughout their hospital stay. The algorithms were applied to the validation sample, and predicted risk probability was generated for each patient from the coefficients. Risk threshold for the algorithms were determined by identifying the cut-off points of risk scores at which the algorithm would have the highest discriminative performance. Clinical pharmacy staffing levels were obtained from the pharmacy department staffing database. Numbers of previous emergency admissions and admission medicines together with age-adjusted co-morbidity and diuretic receipt formed a 12-month post-discharge and/or readmission risk algorithm. Age-adjusted co-morbidity proved to be the best index to predict mortality. Increased numbers of clinical pharmacy staff at ward level was correlated with a reduction in risk-adjusted mortality index (RAMI). Algorithms created were valid in predicting risk of in-hospital and post-discharge mortality and risk of hospital readmission 3, 6 and 12 months post-discharge. The provision of ward-based clinical pharmacy services is a key component to reducing RAMI and enabling the full benefits of pharmacy input to patient care to be realized. © 2014 John Wiley & Sons, Ltd.

    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

    In recent years, there has been a significant effort to identify high-risk plaques in vivo prior to acute events. While number of imaging modalities have been developed to identify morphologic characteristics of high-risk plaques, prospective natural-history observational studies suggest that vulnerability is not solely dependent on plaque morphology and likely involves additional contributing mechanisms. High wall shear stress (WSS) has recently been proposed as one possible causative factor, promoting the development of high-risk plaques. High WSS has been shown to induce specific changes in endothelial cell behavior, exacerbating inflammation and stimulating progression of the atherosclerotic lipid core. In line with experimental and autopsy studies, several human studies have shown associations between high WSS and known morphological features of high-risk plaques. However, despite increasing evidence, there is still no longitudinal data linking high WSS to clinical events. As the interplay between atherosclerotic plaque, artery, and WSS is highly dynamic, large natural history studies of atherosclerosis that include WSS measurements are now warranted. This review will summarize the available clinical evidence on high WSS as a possible etiological mechanism underlying high-risk plaque development.

    Although high-risk sport participants are typically considered a homogenous risk-taking population, attitudes to risk within the high-risk domain can vary considerably. As no validated measure allows researchers to assess risk taking within this domain, we validated the Risk Taking Inventory (RTI) for high-risk sport across four studies. The RTI comprises seven items across two factors: deliberate risk taking and precautionary behaviors. In Study 1 (n = 341), the inventory was refined and tested via a confirmatory factor analysis used in an exploratory fashion. The subsequent three studies confirmed the RTI's good model-data fit via three further separate confirmatory factor analyses. In Study 2 (n = 518) and in Study 3 (n = 290), concurrent validity was also confirmed via associations with other related traits (sensation seeking, behavioral activation, behavioral inhibition, impulsivity, self-esteem, extraversion, and conscientiousness). In Study 4 (n = 365), predictive validity was confirmed via associations with mean accidents and mean close calls in the high-risk domain. Finally, in Study 4, the self-report version of the inventory was significantly associated with an informant version of the inventory. The measure will allow researchers and practitioners to investigate risk taking as a variable that is conceptually distinct from participation in a high-risk sport.

    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.

    2005-01-01

    The psychological adjustments of "normal" pregnancy are complex, and those of high-risk pregnancy are even more pronounced and severe. A pregnancy may be determined to be at high risk because of obstetric factors in previous pregnancies or the present one; more general medical factors, such as preexisting or emergent disease (often, diabetes); and conditions that are, themselves, psychosocial: anxiety disorders (GAD, OCD, panic disorder, PTSD), mood disorders, and schizophrenia, all of which are a background for a disturbed pregnancy and might complicate a pregnancy denominated high risk for some other reason. This paper discusses these concepts and, in addition, includes sections on pregnancy in adolescence, in the developmentally disabled, and in the situation of chemical dependence (substance abuse).

    Purpose The aim of the present study was to evaluate the effectiveness of hyaluronic acid (HA) in the prevention of acute and late vaginal toxicities after high-dose-rate (HDR) vaginal brachytherapy (BT). Material and methods Between January 2011 and January 2015, we retrospectively analyzed 126 patients with endometrial cancer who underwent extrafascial hysterectomy with or without lymphadenectomy and adjuvant HDR-vaginal BT +/– adjuvant chemotherapy. The total dose prescription was 21 Gy in 3 fractions (one fraction for week). Vaginal ovules containing 5 mg of HA were given for whole duration of vaginal BT and for the two following weeks. Acute and late toxicities were evaluated according to CTCAE vs 4.02. Results According to the revised FIGO 2009 classification, most tumors were in stage IA (30.9%) and in stage IB (57.9%). Thirty-three patients (26.2%) received adjuvant chemotherapy before vaginal BT. Five-year disease-free survival (DFS) and five-year overall survival (OS) were 88% and 93%, respectively. The most common grade 1-2 acute toxicities were vaginal inflammation (18 patients, 14.3%) and dyspareunia (7 patients, 5.5%). Two patients (1.6%) had more than one toxicity. Late toxicity occurred in 20 patients (15.9%). Grade 1-2 late toxicities were fibrosis (14 patients, 11.1%) and telangiectasias (7 patients, 5.5%). Six patients (4.8%) had more than one late toxicity. No grade 3 or higher acute or late toxicities were observed. Conclusions These results appear to suggest that the local therapy with HA is of clinical benefit for intermediate risk endometrial cancer patients who receive adjuvant HDR-vaginal BT after surgery. A randomized trial comparing HA treatment vs. no local treatment in this clinical setting is warranted to further evaluate the efficacy of HA in preventing vaginal BT-related vaginal toxicity.

    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.

    Organizations in developed countries with limited financial resources may find it difficult to determine whether it is preferable to use these resources for HPV vaccination, management of HPV-related diseases, or a "hybrid" strategy, such as vaccinating only the highest risk individuals. We determined the organizational costs and clinical impacts of three different organizational approaches to female HPV vaccination in a low-resource setting, including vaccinating everyone, vaccinating no one, or vaccinating only those considered high-risk. To determine patients at highest risk, HPV risk factors were identified using information routinely gathered at the annual preventive maintenance visit. The three vaccination strategies were then compared using a decision tree analysis. The three strategies demonstrated very little difference in cost. However, the least expensive strategy was to vaccinate no one. In contrast, the strategy with the best clinical outcomes was for the organization to vaccinate everyone. Organizations with limited resources must decide how to best allocate these funds to provide the greatest clinical benefits. This study showed little difference in costs but improved clinical outcomes when using the universal HPV vaccination strategy. Thus, the improvement in clinical outcomes when vaccinating everyone may be worth the relatively small increase in cost of vaccinating everyone.

    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

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

    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.

    Full Text Available The research attempted to compose a psycjhological profile of high risk sports athletes, based on personality, values and sensation seeking. 38 high risk sports athletes participated in the research (alpinists, sky divers, parachute gliders, white water kayakers, downhill mountain bikers, motocross riders, downhill skiers and Nordic jumpers, the non risk sports athletes consisted of 38 swimmers, track athletes, sailers, still water kayakers, rowers, Nordic skiers, sports climbers and karate players, whereas non athletes were equalled with both groups in age and education and included 76 non athletes. We used the self descriptive scale Big five observer, Musek's Value scale and Zuckerman' Sensation seeking scale IV. The dimensions, obtained from the discrimination analysis, were named personality maturity and sensation seeking in a social environment. Our results show that high risk sports athletes are more mature personalities than non risk sports athletes and non athletes and that they do not attempt to find stimulation in social environments. We also suggest some possibilities for further research.

Material and methods: The study included 600 people (155 men and 445 women with low and moderate cardiovascular risk on the SCORE scale. All patients were examined with duplex scanning of the carotid arteries (DSCA to the determined of the thickness of the intima – media (IMT, the presence of atherosclerotic plaques (ASP; it has also been performed sphygmographic computer (SC with automatic estimation of brachial-ankle pulse wave velocity (baPWV, biochemical analysis of blood lipid spectrum. Results: The frequency of ASP was 59.5% (357 out of 600, and a thickening of thecomplex "intima-media" (IMT> 0.9 mm was detected in only 5% of the cases (28 persons out of 600, that indicated a slight contribution to the magnitude of the risk of such parameters as the IMT. The total number of patients with signs of preclinicallesions of the arterial wall (the presence of ASP and/or increased baPWV was 337 (56% of 600. Our results showed that the presence of subclinical atherosclerosis is in itself a risk factor. Conclusion: The usage of instrumental methods of research (DSCA, SC allowed to detect 32% of individuals with high CVR from 600 previously classified as low and moderate risk on SCORE scale. In our opinion, the proposed algorithm is convenient and easy to use for transfer of the patients into high-risk group.

    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.

    2011-05-01

    Full Text Available Abstract Background Patients at higher than average risk of heritable cancer may process risk information differently than the general population. However, little is known about clinical, demographic, or psychosocial predictors that may impact risk perception in these groups. The objective of this study was to characterize factors associated with perceived risk of developing cancer in groups at high risk for cancer based on genetics or family history. Methods We searched Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, and Scopus from inception through April 2009 for English-language, original investigations in humans using core concepts of "risk" and "cancer." We abstracted key information and then further restricted articles dealing with perceived risk of developing cancer due to inherited risk. Results Of 1028 titles identified, 53 articles met our criteria. Most (92% used an observational design and focused on women (70% with a family history of or contemplating genetic testing for breast cancer. Of the 53 studies, 36 focused on patients who had not had genetic testing for cancer risk, 17 included studies of patients who had undergone genetic testing for cancer risk. Family history of cancer, previous prophylactic tests and treatments, and younger age were associated with cancer risk perception. In addition, beliefs about the preventability and severity of cancer, personality factors such as "monitoring" personality, the ability to process numerical information, as well as distress/worry also were associated with cancer risk perception. Few studies addressed non-breast cancer or risk perception in specific demographic groups (e.g. elderly or minority groups and few employed theory-driven analytic strategies to decipher interrelationships of factors. Conclusions Several factors influence cancer risk perception in patients at elevated risk for cancer. The science of characterizing and improving risk perception in cancer for high risk groups, although

    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.

  20. Clinical implications of genomics for cancer risk genetics.

    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.

    Full Text Available Abstract Background To determine if recommended treatment targets, as specified in clinical practice guidelines for the management of cardiovascular disease, reduces the risk of renal complications in high risk patient populations. Methods This was a cohort study. Participants in Utrecht, The Netherlands either at risk of, or had cardiovascular disease were recruited. Cardiovascular treatment targets were achievement of control in systolic and diastolic blood pressure, total and low-density cholesterol, and treatment of albuminuria. Outcome measures were time to development of end stage renal failure or symptomatic renal atherosclerotic disease requiring intervention. Results The cohort consisted of 7,208 participants; 1,759 diabetics and 4,859 with clinically manifest vascular disease. The median age was 57 years and 67% were male. Overall, 29% of the cohort achieved the treatment target for systolic blood pressure, 39% for diastolic blood pressure, 28% for total cholesterol, 31% for LDL cholesterol and 78% for albuminuria. The incidence rate for end stage renal failure and renal atherosclerotic disease reduced linearly with each additional treatment target achieved (p value less than 0.001. Achievement of any two treatment targets reduced the risk of renal complications, hazard ratio 0.46 (95% CI 0.26-0.82. For patients with clinically manifest vascular disease and diabetes, the hazard ratios were 0.56 (95% CI 0.28 - 1.12 and 0.28 (95%CI 0.10 - 0.79 respectively. Conclusion Clinical guidelines for cardiovascular disease management do reduce risk of renal complications in high risk patients. Benefits are seen with attainment of any two treatment targets.

  3. A probabilistic topic model for clinical risk stratification from electronic health records.

    Risk stratification aims to provide physicians with the accurate assessment of a patient's clinical risk such that an individualized prevention or management strategy can be developed and delivered. Existing risk stratification techniques mainly focus on predicting the overall risk of an individual patient in a supervised manner, and, at the cohort level, often offer little insight beyond a flat score-based segmentation from the labeled clinical dataset. To this end, in this paper, we propose a new approach for risk stratification by exploring a large volume of electronic health records (EHRs) in an unsupervised fashion. Along this line, this paper proposes a novel probabilistic topic modeling framework called probabilistic risk stratification model (PRSM) based on Latent Dirichlet Allocation (LDA). The proposed PRSM recognizes a patient clinical state as a probabilistic combination of latent sub-profiles, and generates sub-profile-specific risk tiers of patients from their EHRs in a fully unsupervised fashion. The achieved stratification results can be easily recognized as high-, medium- and low-risk, respectively. In addition, we present an extension of PRSM, called weakly supervised PRSM (WS-PRSM) by incorporating minimum prior information into the model, in order to improve the risk stratification accuracy, and to make our models highly portable to risk stratification tasks of various diseases. We verify the effectiveness of the proposed approach on a clinical dataset containing 3463 coronary heart disease (CHD) patient instances. Both PRSM and WS-PRSM were compared with two established supervised risk stratification algorithms, i.e., logistic regression and support vector machine, and showed the effectiveness of our models in risk stratification of CHD in terms of the Area Under the receiver operating characteristic Curve (AUC) analysis. As well, in comparison with PRSM, WS-PRSM has over 2% performance gain, on the experimental dataset, demonstrating that

    Neuroblastoma is a malignant paediatric tumour of the sympathetic nervous system. Roughly half of these tumours regress spontaneously or are cured by limited therapy. By contrast, high-risk neuroblastomas have an unfavourable clinical course despite intensive multimodal treatment, and their molecular basis has remained largely elusive. Here we have performed whole-genome sequencing of 56 neuroblastomas (high-risk, n = 39; low-risk, n = 17) and discovered recurrent genomic rearrangements affecting a chromosomal region at 5p15.33 proximal of the telomerase reverse transcriptase gene (TERT). These rearrangements occurred only in high-risk neuroblastomas (12/39, 31%) in a mutually exclusive fashion with MYCN amplifications and ATRX mutations, which are known genetic events in this tumour type. In an extended case series (n = 217), TERT rearrangements defined a subgroup of high-risk tumours with particularly poor outcome. Despite a large structural diversity of these rearrangements, they all induced massive transcriptional upregulation of TERT. In the remaining high-risk tumours, TERT expression was also elevated in MYCN-amplified tumours, whereas alternative lengthening of telomeres was present in neuroblastomas without TERT or MYCN alterations, suggesting that telomere lengthening represents a central mechanism defining this subtype. The 5p15.33 rearrangements juxtapose the TERT coding sequence to strong enhancer elements, resulting in massive chromatin remodelling and DNA methylation of the affected region. Supporting a functional role of TERT, neuroblastoma cell lines bearing rearrangements or amplified MYCN exhibited both upregulated TERT expression and enzymatic telomerase activity. In summary, our findings show that remodelling of the genomic context abrogates transcriptional silencing of TERT in high-risk neuroblastoma and places telomerase activation in the centre of transformation in a large fraction of these tumours.

    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

    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

    To investigate the factors influencing the compliance of pre-exposure prophylaxis (PrEP) amonghigh-risk groups of human immunodeficiency virus (HIV). Methods A total of 352 subjects were selected into the cohort by non-probability sampling, including 153 men who have sex with men (MSM) , 36 female sex workers (FSMs) , and 163 fixed sex partners(PARs) of HIV carriers. Each subject was randomly given a medication regimen of either once daily or twice a week. The pre-exposure prophylaxis compliance was evaluated by observing the maintenance of the cohort and medication omission every 4 weeks from week 0 to week 28. Cochran-Mantel-Haenszel (CMH) test was employed to conduct univariate analysis and logistic regression was adopted for multiple variable analysis. Results It was found that 76. 70% (270/352) of the subjects finished the 28-week-observation in this PrEP clinical trial among high-risk groups of HIV. The medication omission rate fluctuated around 35% during the follow-up, with the total compliance score being 82. 12 + 27. 48 and the median score being 95. 24. Logistic regression suggested that the monthly income, presence of worries or difficulties during the trials, need for medical service, and the way of follow-up were the factors influencing the maintenance of cohort. The marital status, medication method, presence of worries or difficulties during the trial, and presence of adverse effect were the influencing factors of medication omission. The population type, number of sex partners, taking of other drugs at the same time, need of medical service during the trial, and way of follow-up were the factors impacting the overall compliance score. Conclusion The compliance of the present PrEP clinical trials among high-risk groups of HIV is high, and it has multiple influencing factors. Compliance management should be reinforced among MSM and FSW populations with greater motility. The cohort management model of follow-up by fixed specialists should be continued

    To identify clinical correlates of person-centered fall risk awareness and their validity for predicting falls. Prospective cohort study. Community. Ambulatory community-dwelling older adults without dementia (N = 316; mean age 78, 55% female). Fall risk awareness was assessed using a two-item questionnaire that asked participants about overall likelihood of someone in their age group having a fall and their own personal risk of falling over the next 12 months. Incident falls were recorded over study follow-up. Fifty-three participants (16.8%) responded positively to the first fall risk awareness question about being likely to have a fall in the next 12 months, and 100 (31.6%) reported being at personal risk of falling over the next 12 months. There was only fair correlation (κ = 0.370) between responses on the two questions. Prior falls and depressive symptoms were associated with positive responses on both fall risk awareness questions. Age and other established fall risk factors were not associated with responses on either fall risk awareness question. The fall risk awareness questionnaire did not predict incident falls or injurious falls. Fall risk awareness is low in older adults. Although person-centered fall risk awareness is not predictive of falls, subjective risk perceptions should be considered when designing fall preventive strategies because they may influence participation and behaviors. © 2016, Copyright the Author Journal compilation © 2016, The American Geriatrics Society.

    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.

    Objectives Huntington’s disease (HD) is a neurodegenerative disorder that produces a bias toward risky, reward-driven decisions in situations where the outcomes of decisions are uncertain and must be discovered. However, it is unclear whether HD patients show similar biases in decision-making when learning demands are minimized and prospective risks and outcomes are known explicitly. We investigated how risk decision-making strategies and adjustments are altered in HD patients when reward contingencies are explicit. Methods HD (N = 18) and healthy control (HC; N = 17) participants completed a risk-taking task in which they made a series of independent choices between a low-risk/low reward and high-risk/high reward risk options. Results Computational modeling showed that compared to HC, who showed a clear preference for low-risk compared to high-risk decisions, the HD group valued high-risks more than low-risk decisions, especially when high-risks were rewarded. The strategy analysis indicated that when high-risk options were rewarded, HC adopted a conservative risk strategy on the next trial by preferring the low-risk option (i.e., they counted their blessings and then played the surer bet). In contrast, following a rewarded high-risk choice, HD patients showed a clear preference for repeating the high-risk choice. Conclusions These results indicate a pattern of high-risk/high-reward decision bias in HD that persists when outcomes and risks are certain. The allure of high-risk/high-reward decisions in situations of risk certainty and uncertainty expands our insight into the dynamic decision-making deficits that create considerable clinical burden in HD.

    The prospective phase 3 PlanB trial used the Oncotype DX(®) Recurrence Score(®) (RS) to define a genomically low-risk subset of clinically high-risk pN0-1 early breast cancer (EBC) patients for treatment with adjuvant endocrine therapy (ET) alone. Here, we report five-year data evaluating the prognostic value of RS, Ki-67, and other traditional clinicopathological parameters. A central tumour bank was prospectively established within PlanB. Following an early amendment, hormone receptor (HR)+ , pN0-1 RS ≤ 11 patients were recommended to omit chemotherapy. Patients with RS ≥ 12, pN2-3, or HR-negative/HER2-negative disease were randomised to anthracycline-containing or anthracycline-free chemotherapy. Primary endpoint: disease-free survival (DFS). PlanB Clinicaltrials.gov identifier: NCT01049425. From 2009 to 2011, PlanB enrolled 3198 patients (central tumour bank, n = 3073) with the median age of 56 years, 41.1% pN+, and 32.5% grade 3 EBC. Chemotherapy was omitted in 348/404 (86.1%) eligible RS ≤ 11 patients. After 55 months of median follow-up, five-year DFS in ET-treated RS ≤ 11 patients was 94% (in both pN0 and pN1) versus 94% (RS 12-25) and 84% (RS > 25) in chemotherapy-treated patients (p five-year overall survival (OS) was 99 versus 97% and 93%, respectively (p 2 cm, and RS, but not IHC4 or Ki-67 were independent adverse factors. If RS was excluded, IHC4 or both Ki-67 and PR entered the model. The impact of RS was particularly pronounced in patients with intermediate Ki-67 (>10%, five-year outcomes in clinically high-risk, genomically low-risk (RS ≤ 11) pN0-1 patients without adjuvant chemotherapy support using RS with standardised pathology for treatment decisions in HR+ HER2-negative EBC. Ki-67 has the potential to support patient selection for genomic testing.

    Identification of factors that confer an increased risk of mortality in hospital acquired sepsis (HAS) is necessary to help prevent, and improve the outcome of, this condition. To evaluate the clinical characteristics and factors associated with mortality in patients with HAS. Retrospective study of patients with HAS in a major Spanish Hospital from 2011 to 2015. Data from adults receiving any of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes associated with sepsis were collected. Those fulfilling the SEPSIS-2 definition with no evidence of infection during the first 48 hours following hospitalization were included (n=196). A multivariate analysis was employed to identify the risk factors of mortality. HAS patients were found to have many of the risk factors associated with cardiovascular disease (male sex, ageing, antecedent of cardiac disease, arterial hypertension, dyslipemia, smoking habit) and cancer. Vascular disease or chronic kidney disease were associated with 28 day mortality. Time from hospital admission to sepsis diagnosis, and the presence of organ failure were risk factors for 28-day and hospital mortality. Experiencing more than one episode of sepsis increased the risk of hospital mortality. "Sepsis Code" for the early identification of sepsis was protective against hospital mortality. We have identified a number of major factors associated to mortality in patients suffering from HAS. Implementation of surveillance programmes for the early identification and treatment of sepsis translate into a clear benefit. Copyright © 2017 The Healthcare Infection Society.

    Full Text Available INTRODUCTION: To develop and test a diabetes risk score to predict incident diabetes in an elderly Spanish Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: A diabetes risk score was derived from a subset of 1381 nondiabetic individuals from three centres of the PREDIMED study (derivation sample. Multivariate Cox regression model ß-coefficients were used to weigh each risk factor. PREDIMED-personal Score included body-mass-index, smoking status, family history of type 2 diabetes, alcohol consumption and hypertension as categorical variables; PREDIMED-clinical Score included also high blood glucose. We tested the predictive capability of these scores in the DE-PLAN-CAT cohort (validation sample. The discrimination of Finnish Diabetes Risk Score (FINDRISC, German Diabetes Risk Score (GDRS and our scores was assessed with the area under curve (AUC. RESULTS: The PREDIMED-clinical Score varied from 0 to 14 points. In the subset of the PREDIMED study, 155 individuals developed diabetes during the 4.75-years follow-up. The PREDIMED-clinical score at a cutoff of ≥6 had sensitivity of 72.2%, and specificity of 72.5%, whereas AUC was 0.78. The AUC of the PREDIMED-clinical Score was 0.66 in the validation sample (sensitivity = 85.4%; specificity = 26.6%, and was significantly higher than the FINDRISC and the GDRS in both the derivation and validation samples. DISCUSSION: We identified classical risk factors for diabetes and developed the PREDIMED-clinical Score to determine those individuals at high risk of developing diabetes in elderly individuals at high cardiovascular risk. The predictive capability of the PREDIMED-clinical Score was significantly higher than the FINDRISC and GDRS, and also used fewer items in the questionnaire.

    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

    Many coronary heart disease (CHD) events occur in individuals classified as intermediate risk by commonly used assessment tools. Over half the individuals presenting with a severe cardiac event, such as myocardial infarction (MI), have at most one risk factor as included in the widely used Framingham risk assessment. Individuals classified as intermediate risk, who are actually at high risk, may not receive guideline recommended treatments. A clinically useful method for accurately predicting 5-year CHD risk among intermediate risk patients remains an unmet medical need. This study sought to develop a CHD Risk Assessment (CHDRA) model that improves 5-year risk stratification among intermediate risk individuals. Assay panels for biomarkers associated with atherosclerosis biology (inflammation, angiogenesis, apoptosis, chemotaxis, etc.) were optimized for measuring baseline serum samples from 1084 initially CHD-free Marshfield Clinic Personalized Medicine Research Project (PMRP) individuals. A multivariable Cox regression model was fit using the most powerful risk predictors within the clinical and protein variables identified by repeated cross-validation. The resulting CHDRA algorithm was validated in a Multiple-Ethnic Study of Atherosclerosis (MESA) case-cohort sample. A CHDRA algorithm of age, sex, diabetes, and family history of MI, combined with serum levels of seven biomarkers (CTACK, Eotaxin, Fas Ligand, HGF, IL-16, MCP-3, and sFas) yielded a clinical net reclassification index of 42.7% (p definition with the MESA samples and inability to include PMRP fatal CHD events. A novel risk score of serum protein levels plus clinical risk factors, developed and validated in independent cohorts, demonstrated clinical utility for assessing the true risk of CHD events in intermediate risk patients. Improved accuracy in cardiovascular risk classification could lead to improved preventive care and fewer deaths.

    @@ The majority of low-risk patients with clinically localized prostate cancer have a high likelihood of disease-free survival,regardless of the treatment option chosen.1 In contrast, patients with high-risk prostate cancer with high Gleason score, elevated prostate-specific antigen level and advanced clinical stage have a high probability of treatment failure after initial management by single-treatment modalities, such as radical pro-statectomy (RP), external beam radiation therapy (EBRT) or brachytherapy.2,3 Therefore, it is extremely important to establish the most effective treatment strategy for patients with high-risk prostate cancer.

    Self-monitoring of blood pressure with self-titration of antihypertensives (self-management) results in lower blood pressure in patients with hypertension, but there are no data about patients in high-risk groups. To determine the effect of self-monitoring with self-titration of antihypertensive medication compared with usual care on systolic blood pressure among patients with cardiovascular disease, diabetes, or chronic kidney disease. A primary care, unblinded, randomized clinical trial involving 552 patients who were aged at least 35 years with a history of stroke, coronary heart disease, diabetes, or chronic kidney disease and with baseline blood pressure of at least 130/80 mm Hg being treated at 59 UK primary care practices was conducted between March 2011 and January 2013. Self-monitoring of blood pressure combined with an individualized self-titration algorithm. During the study period, the office visit blood pressure measurement target was 130/80 mm Hg and the home measurement target was 120/75 mm Hg. Control patients received usual care consisting of seeing their health care clinician for routine blood pressure measurement and adjustment of medication if necessary. The primary outcome was the difference in systolic blood pressure between intervention and control groups at the 12-month office visit. Primary outcome data were available from 450 patients (81%). The mean baseline blood pressure was 143.1/80.5 mm Hg in the intervention group and 143.6/79.5 mm Hg in the control group. After 12 months, the mean blood pressure had decreased to 128.2/73.8 mm Hg in the intervention group and to 137.8/76.3 mm Hg in the control group, a difference of 9.2 mm Hg (95% CI, 5.7-12.7) in systolic and 3.4 mm Hg (95% CI, 1.8-5.0) in diastolic blood pressure following correction for baseline blood pressure. Multiple imputation for missing values gave similar results: the mean baseline was 143.5/80.2 mm Hg in the intervention group vs 144.2/79.9 mm Hg in the control group, and

    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.

    Background The Tinetti scale is a simple clinical tool designed to predict risk of falling by focusing on gait and stance impairment in elderly persons. Gait impairment is also associated with white matter (WM) abnormalities. Objective To test the hypothesis that elderly subjects at risk for falling, as determined by the Tinetti scale, have specific patterns of WM abnormalities on diffusion tensor imaging. Design, Setting, and Patients Community-based cohort of 125 homebound elderly individuals. Main Outcome Measures Diffusion tensor imaging scans were analyzed using tract-based spatial statistics analysis to determine the location of WM abnormalities in subjects with Tinetti scale scores of 25 or higher (without risk of falls) and lower than 25 (with risk of falls). Multivariate linear least squares correlation analysis was performed to determine the association between Tinetti scale scores and local fractional anisotropy values on each skeletal voxel controlling for possible confounders. Results In subjects with risk of falls (Tinetti scale score scores, while the other locations were unrelated to these scores. Conclusions Elderly individuals at risk for falls as determined by the Tinetti scale have WM abnormalities in specific locations on diffusion tensor imaging, some of which correlate with cognitive function scores.

    Hypertension control rate in the US is low with the current clinical practice (JNC 7) and cardiovascular disease (CVD) remain is the leading cause of morbidity and mortality. A 6-month clinical trial simulation case study testing different virtual clinical practice strategies was performed in an attempt to increase the control rate. The CVD risk was calculated using the Framingham CVD risk model at baseline and 6 months post-treatment. The estimated CVD events for the baseline patient sample without any treatment was 998 (95% CI: 967-1,026) over 6 months in 100,000 patients. Treating these patients for 6 months with current clinical practice, high dose strategy, high dose with low target BP strategy resulted in a reduction in CVD events of 191(95% CI: 169-205), 284 (95% CI: 261-305), and 353 (95% CI: 331-375), respectively. Hence the two alternative strategies resulted in an increase in treatment effect by 49% (95%CI: 44-59%) and 85% (95%CI: 79-99%), respectively. The increased safety with the current low dose strategy may potentially be offset by increased CVD risk in the time necessary to control hypertension.

    Background Early diagnosis of COPD is often not achieved due to limited recognition and limited access to the pulmonary function test. Our hypothesis was that lung function decline may be different between populations with mild COPD and those who are at high risk and do not receive treatment. Patients and methods Subjects with mild COPD and those from a high-risk COPD population were recruited from a community-based COPD epidemiological study after obtaining consent. Baseline clinical characteristics, symptom questionnaire, spirometry, low-dose computed tomography (LDCT) chest scan, and blood plasma biomarker data were collected initially and then 1 year later. Results A total of 617 participants were recruited, and 438 eventually completed the first-year follow-up visit; 72 participants (46 males) were in the mild COPD group, and 225 participants (165 males) were in the high-risk group. The mean forced expiratory volume in the first second of expiration (FEV1) decline in the mild COPD group was 129 mL, which was significantly higher than the 30 mL decline in the high-risk population group (P=0.005). Group category (odds ratio [OR] =0.230) and COPD Assessment Test (CAT) score (OR =9.912) were independent risk factors for an FEV1% predicted decline of >15% for all participants. In the mild COPD group, patients with a higher CAT (OR =5.310) and Emphysema Index (OR =5.681) were associated with a FEV1% predicted decline of >15% at the first-year follow-up. No factor showed a significantly predictive effect on FEV1 decline in the high-risk COPD group. Conclusion Group category was an independent influential factor associated with FEV1 decline.

    The term 'wandering spleen' refers to an abnormal hypermobility of the spleen, which may be congenital or acquired. The absence or abnormal laxity of splenic ligaments combined with an abnormally long and mobile vascular pedicle predispose to complications such as torsion of the splenic pedicle, infarction and splenic vein thrombosis. The clinical presentation of such disease is highly variable. In this case, we describe an asymptomatic case of wandering spleen in high thrombotic risk patients with cavernoma of splenic vein and infarction of the spleen. Physical examination was normal except the enlarged and no tender consistency spleen palpable at left iliac fossa. Ultrasonography revealed enlarged spleniform mass below its normal position suggesting vascular impairment and subsequently has been confirmed by colour Doppler ultrasound and computed tomography. The family history was positive for ischemic thrombotic vascular diseases and the screening for thrombotic risk has revealed hyperhomocysteinemia, thrombophilic homozygous gene mutations for factor V (H1299R) and MTHFR (C677T). For high thrombotic risk, prophylaxis postsplenectomy was suggested according to the international recommendations with subcutaneous low molecular weight heparin, associated with a preventive treatment with acetyl salicylic acid and folic acid along with B-vitamin. This case report may be helpful for clinicians involved in the care of splenectomized patients, because it has shown the importance of an appropriate pre and postoperative antithrombotic management to reduce as soon as possible the risk of thrombotic events in such patients after splenectomy.

    The objective was to assess whether pediatric risk factors predict cardiovascular disease (CVD), impaired fasting glucose (IFG) + type 2 diabetes mellitus (T2DM), and high blood pressure (HBP) in young adulthood. We performed a prospective follow-up of 909 public-parochial suburban schoolchildren first studied at ages 6 to 18 years and 26 years later at a mean age of 38 years. Pediatric triglycerides (TGs), blood pressure, low-density lipoprotein cholesterol, body mass index, and glucose above and high-density lipoprotein cholesterol below established pediatric cutoffs, along with race, cigarette smoking, family history of CVD, T2DM, and HBP, were assessed as determinants of young adult CVD, a composite variable including IFG + T2DM and HBP. By stepwise logistic regression, adult CVD (19 yes, 862 no) was associated with pediatric high TG (odds ratio [OR], 5.85; 95% confidence interval [CI], 2.3-14.7). High TG in pediatric probands with young adult CVD was familial and was associated with early CVD in their high-TG parents. Adult IFG + T2DM (114 yes, 535 no) was associated with parental T2DM (OR, 2.2; 95% CI, 1.38-3.6), high childhood glucose (OR, 4.43; 95% CI, 2-9.7), and childhood cigarette smoking (OR, 1.64; 95% CI, 1.03-2.61). Adult HBP (133 yes, 475 no) was associated with pediatric high body mass index (OR, 2.7; 95% CI, 1.7-4.3) and HBP (OR, 2.5; 95% CI, 1.5-4.3). Pediatric risk factors are significantly, independently related to young adult CVD, IFG + T2DM, and HBP. Identification of pediatric risk factors for CVD, IFG + T2DM, and HBP facilitates initiation of primary prevention programs to reduce development of adult CVD, IFG + T2DM, and HBP.

    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

    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.

  16. Impact of newly recommended HbA1c-based diabetes diagnostic criteria on the prevalence of diabetes and high risk individual in clinical and community population in China

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    @@ To the editor: Recently, the International Expert Committee recommended using HbAlc as a diagnosing tool for diabetes and suggested HbAlc value of 6.5% as cut-off for the diagnosis.~1 In this recommendation, pre-diabetes was replaced by "sub-diabetes or high risk status" which was defined by HbAlc between 6.0% and 6.5%. The recommendation has triggered wide discussion on its potential influence on diabetes care, for example, the impact of the new diabetes diagnosis criteria on the prevalence of diabetes. We have noticed that the level of HbAlc correlated with oral glucose tolerance test (OGTT) based diabetes diagnosis criteria~2 is lower than 6.5%.~(3,4) We hypothesized that the new diagnosis criteria will reduce the prevalence of both diabetes and high risk population in Chinese population. To test this hypothesis, we calculated the prevalence of diabetes and high risk individuals in both community and hospital based diabetes screening population by using both OGTT based2 and HbAlc based diagnosis criteria.

    Informed consent is an essential component of medical practice, and especially so in procedural based specialties which entail varying degrees of risk. Breast cancer is one of the most common cancers in women, and as such is the focus of extensive research and significant media attention. Despite this, considerable misperception exists regarding the risk of developing breast cancer. This study aims to examine the accuracy of risk perception of women attending a breast cancer family history clinic, and to explore the relationship between risk perception accuracy and health literacy. A cross-sectional study of women attending a breast cancer family history clinic (n = 86) was carried out, consisting of a patient survey and a validated health literacy assessment. Patients' perception of personal and population breast cancer risk was compared to actual risk as calculated by a validated risk assessment tool. Significant discordance between real and perceived risks was observed. The majority (83.7%) of women overestimated their personal lifetime risk of developing breast cancer, as well as that of other women of the same age (89.5%). Health literacy was considered potentially inadequate in 37.2% of patients; there was a correlation between low health literacy and increased risk perception inaccuracy across both personal ten-year (rs = 0.224, p = 0.039) and general ten-year population estimations. (rs = 0.267, p = 0.013). Inaccuracy in risk perception is highly prevalent in women attending a breast cancer family history clinic. Health literacy inadequacy is significantly associated with this inaccuracy.

    Full Text Available In Taiwan, the prevalence of hyperlipidemia increased due to lifestyle and dietary habit changes. Low density lipoprotein cholesterol (LDL-C and non-high density lipoprotein cholesterol (non-HDL-C are all significant predicting factors of coronary artery disease in Taiwan. We recognized that lipid control is especially important in patients with existed atherosclerotic cardiovascular diseases (ASCVD, including coronary artery disease (CAD, ischemic stroke and peripheral arterial disease (PAD. Because the risk of ASCVD is high in patients with diabetes mellitus (DM, chronic kidney disease (CKD and familial hypercholesterolemia (FH, lipid control is also necessary in these patients. Lifestyle modification is the first step to control lipid. Weight reduction, regular physical exercise and limitation of alcohol intake all reduce triglyceride (TG levels. Lipid-lowering drugs include HMG-CoA reductase inhibitors (statins, cholesterol absorption inhibitors (ezetimibe, proprotein convertase subtilisin/kexin type 9 (PCSK9 inhibitors, nicotinic acids (niacin, fibric acids derivatives (fibrates, and long-chain omega-3 fatty acids. Statin is usually the first line therapy. Combination therapy with statin and other lipid-lowering agents may be considered in some clinical settings. For patients with acute coronary syndrome (ACS and stable CAD, LDL-C 40 in men and >50 mg/dL in women in DM. LDL-C increased CV risk in patients with CKD. In adults with glomerular filtration rate (GFR < 60 mL/min/1.73m2 without chronic dialysis (CKD stage 3–5, statin therapy should be initiated if LDL-C ≥ 100 mg/dL. Ezetimibe can be added to statin to consolidate the CV protection in CKD patients. Mutations in LDL receptor, apolipoprotein B and PCSK9 genes are the common causes of FH. Diagnosis of FH usually depends on family history, clinical history of premature CAD, physical findings of xanthoma or corneal arcus and high levels of LDL-C. In addition to conventional lipid

    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.

    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.

  7. Clinical assessment of anti-viral CD8+ T cell immune monitoring using QuantiFERON-CMV® assay to identify high risk allogeneic hematopoietic stem cell transplant patients with CMV infection complications.

    Full Text Available The reconstitution of anti-viral cellular immunity following hematopoietic stem cell transplantation (HSCT is crucial in preventing cytomegalovirus (CMV-associated complications. Thus immunological monitoring has emerged as an important tool to better target pre-emptive anti-viral therapies. However, traditional laboratory-based assays are too cumbersome and complicated to implement in a clinical setting. Here we conducted a prospective study of a new whole blood assay (referred to as QuantiFERON-CMV® to determine the clinical utility of measuring CMV-specific CD8+ T-cell responses as a prognostic tool. Forty-one evaluable allogeneic HSCT recipients underwent weekly immunological monitoring from day 21 post-transplant and of these 21 (51.2% showed CMV reactivation and 29 (70.7% developed acute graft-versus-host disease (GvHD. Patients with acute GvHD (grade ≥ 2 within 6 weeks of transplant showed delayed reconstitution of CMV-specific T-cell immunity (p = 0.013 and a higher risk of CMV viremia (p = 0.026. The median time to stable CMV-specific immune reconstitution was 59 days and the incidence of CMV reactivation was lower in patients who developed this than those who did not (27% versus 65%; p = 0.031. Furthermore, a failure to reconstitute CMV-specific immunity soon after the onset of CMV viraemia was associated with higher peak viral loads (5685 copies/ml versus 875 copies/ml; p = 0.002. Hence, QuantiFERON-CMV® testing in the week following CMV viremia can be useful in identifying HSCT recipients at risk of complicated reactivation.

    The high topographic and vegetation heterogeneity makes Italy vulnerable to forest fires both in the summer and in winter. In particular, northern regions are predominantly characterized by a winter fire regime, mainly due to frequent extremely dry winds from the north, while southern and central regions and the large islands are characterized by a severe summer fire regime, because of the higher temperatures and prolonged lack of precipitation. The threat of wildfires in Italy is not confined to wooded areas as they extend to agricultural areas and urban-forest interface areas. The agricultural and rural areas, in the last century, have been gradually abandoned, especially in areas with complex topography. Many of these areas were subject to reforestation, leading to the spread of pioneer species mainly represented by Mediterranean conifer, which are highly vulnerable to fire. Because of the frequent spread of fire, these areas are limited to the early successional stages, consisting mainly of shrub vegetation; its survival in the competition with the climax species being ensured by the spread of fire itself. Due to the frequency of fire ignition — almost entirely man caused — the time between fires on the same area is at least an order of magnitude less than the time that would allow the establishment of forest climax species far less vulnerable to fire. In view of the limited availability of fire risk management resources, most of which are used in the management of national and regional air services, it is necessary to precisely identify the areas most vulnerable to fire risk. The few resources available can thus be used on a yearly basis to mitigate problems in the areas at highest risk by defining a program of forest management interventions, which is expected to make a significant contribution to the problem in a few years' time. The goal of such detailed planning is to dramatically reduce the costs associated with water bombers fleet management and fire

    Objective To describe the different risk factors from suspected NEC, diagnosed NEC, and death in children, as well as explore the better treatment. Methods We selected NEC children from the Children's Hospital of SuZhou between January 1, 2010 to January 1, 2013, to compare risk factors, clinical features, treatment and complication between suspected NEC, diagnosis NEC and death in children. Results We have studied 91 children with NEC, including 21 children with Bell stageⅠ, 48 children with Bell stageⅡ, and 22 children with Bell stageⅢ. There were 9 cases of surgical patients among these children. And 17 cases were dead, the mortality rate was 18.68%. 74%of death children in NEC died within 7 days after the diagnose of the NEC, this part of the rapid death in children were in all gestational age, including full-term infants and premature infants. In the analysis, the main risk factors of death in children, including lower gestational age(P=0.035), lower birth weight(P=0.044), the use of mechanical ventilation(P<0.0001) and the seriousness of the disease. In the treatment, fasting time in death children was shorter than the survival one (P=0.055), antibiotic treatment time was shorter than the survival of patients (P<0.0001), and with more use of assisted ventilation therapy in children (P<0.0001),and death patients of NEC were more often complicated by apnea, short bowel syndrome, peritonitis, DIC, neurological sequelae (P<0.05), suggesting that the disease of death patients was more severe than the survival one. Conclusion NEC is associated with high mortality. The main causes of death were associated with immaturity, lower birth weight, and severity of illness.%目的:本文的目的在于探讨不同分期新生儿坏死性小肠结肠炎(NEC)的高危因素特点及相应的诊疗措施。方法回顾性分析2010年1月1日至2013年1月1日入住本院NICU的91例NEC患儿的临床资料,用以比较NEC不同分期即疑似、确诊及死亡

    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.

    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.

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.

    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.

    The idea of targeted screening for colorectal cancer based on risk profiles originates from its benefits to improve detection yield and optimize screening efficiency. Clinically, it allows individuals to be more aware of their own risk and make informed decisions on screening choice. From a public health perspective, the implementation of risk stratification strategies may better justify utilization of colonoscopic resources, and facilitate resource-planning in the formulation of population-based screening programmes. There are several at-risk groups who should receive earlier screening, and colonoscopy is more preferred. This review summarizes the currently recommended CRC screening strategies among subjects with different risk factors, and introduces existing risk scoring systems. Additional genetic, epidemiological, and clinical parameters may be needed to enhance their performance to risk-stratify screening participants. Future research studies should refine these scoring systems, and explore the adaptability, feasibility, acceptability, and user-friendliness of their use in clinical practice among different population groups.

    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.

    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

  1. Challenging Propofol Sedation in Gastrointestinal Endoscopy: High Risk Patients and High Risk Procedures

    Directory of Open Access Journals (Sweden)

    Eduardo Redondo-Cerezo

    2012-12-01

    Full Text Available Sedation is increasingly becoming a must for most endoscopic procedures. Non-anesthesiologist administration of propofol is the standard of practice in many European countries. Nevertheless, despite anesthesiology societies concerns about sedation guided by endoscopist, practitioners find some limits to propofol administration, related to high risk patients or high risk and complex procedures, which can be long lasting and technically challenging. The main patient related risk factors for sedation are elderly patients, obesity, ASA≥3 patients, individuals with craniofacial abnormalities or with pharyngolaringeal tumors, patients with an acute gastrointestinal bleeding, under pain medications, sedatives, antidepressants, or who consume significant amounts of alcohol or drugs. Procedure related risk factors have more to do with the duration and complexity of the procedure than with other factors, in which considering a general anesthesia allows the endoscopist to concentrate on a difficult task. Published papers addressing the most challenging sedation groups in endoscopy are exploring and even trespassing previously assumed frontiers, and new scenarios are opening to the endoscopist, increasing his/her autonomy, reducing costs and giving patients levels of comfort previously unknown. In this review we analyse each risk group determining the ones in which a sedation protocol could be widely applied, and other in which the published evidence does not guarantee a safe endoscopist guided propofol sedation.

    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.

    For health care systems in recent years, patient safety has increasingly become a priority issue. National and international strategies have been considered to attempt to overcome the most prominent hazards while patients are receiving health care. Thereby, clinical risk management (CRM) plays a dominant role in enabling the identification, analysis, and management of potential risks. CRM implementation into routine procedures within complex hospital organizations is challenging, as in the past, organizational change strategies using a top-down approach have often failed. Therefore, one of our main objectives was to educate a certain number of risk managers in facilitating CRM using a bottom-up approach. To achieve our primary purpose, five project strands were developed, and consequently followed, introducing CRM: corporate governance, risk management (RM) training, CRM process, information, and involvement. The core part of the CRM process involved the education of risk managers within each organizational unit. To account for the size of the existing organization, we assumed that a minimum of 1 % of the workforce had to be trained in RM to disseminate the continuous improvement of quality and safety. Following a roll-out plan, CRM was introduced in each unit and potential risks were identified. Alongside the changes in the corporate governance, a hospital-wide CRM process was introduced resulting in 158 trained risk managers correlating to 2.0 % of the total workforce. Currently, risk managers are present in every unit and have identified 360 operational risks. Among those, 176 risks were scored as strategic and clustered together into top risks. Effective meeting structures and opportunities to share information and knowledge were introduced. Thus far, 31 units have been externally audited in CRM. The CRM approach is unique with respect to its dimension; members of all health care professions were trained to be able to identify potential risks. A network of risk

    A high suicide risk has been reported among veterinarians in comparison to the general population. Postulated causes have included depression, substance abuse, work-related stress, reluctance to admit psychiatric problems, and access to lethal drugs and/or familiarity with euthanasia. Members of the Student Chapter of the American Veterinary Medical Association (AVMA), all veterinarians licensed in Alabama, and all US veterinary-association executive directors were surveyed regarding their attitudes concerning mental health issues, including veterinarian suicide. Only 10% of veterinary student respondents (N=58) believed that suicide risk is higher among veterinarians than in the general population. Of the 22 state associations' executive directors who participated in the survey, 37% believed that suicide is a significant concern for veterinarians and only 44% indicated that a veterinary wellness program was available in their respective states. Of the 1,455 licensed veterinarians in Alabama, 701 responded to the survey; 11% of respondents believed that suicide among veterinarians was a problem. In addition, 66% of respondents indicated that they had been "clinically depressed," but 32% of those with depression had not sought treatment. More females (27%) than males (20%) admitted that they had "seriously considered suicide" (pveterinarians were more likely than male veterinarians (15% versus 7%) to indicate that they were "not sure they'd made the right career choice" (pveterinarians not only have a higher risk of suicide but that they also have fewer support structures. The wide discrepancies between the published risk of suicide for veterinarians and their own views of their risk suggests an inadequate awareness of their own mental health vulnerability which could put them at higher risk.

    With a population of 1.1 billion, India is considered to be a country in which effective prevention interventions could contain the development of a human immunodeficiency virus (HIV) epidemic. Heterosexual transmission accounts for 85 % of the extant HIV infections. This study sought to assess the feasibility of conducting a group, culturally tailored behavioral intervention and its impact on sexual barrier use, self-efficacy, knowledge, conflict resolution, and coping among high-risk heterosexual couples in Northern India. This pilot study was conducted at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India from February 2008 to January 2009. Thirty sexually active high-risk couples were drawn from a convenience sample of PGIMER patients attending infectious disease and family planning clinics. Couples participated in 1 month of three weekly gender-concordant behavioral intervention groups and were individually administered assessments preintervention and post-intervention. The intervention was tailored to the Northern Indian context and addressed sexual barrier use, human immunodeficiency virus (HIV)/sexually transmitted infection transmission, and cognitive behavioral skill building focusing on sexual negotiation and communication. The participants had a mean age of 32 years (men) and 29 years (women), and the majority had at least 10 years of education. At baseline, the majority reported inconsistent condom use (communication without increasing intimate partner violence in high-risk couples may be an important adjunct to preventing the development of a generalized epidemic in India.

    Breast density is routinely assessed qualitatively in screening mammography. However, it is challenging to quantitatively determine a 3D density from a 2D image such as a mammogram. Furthermore, dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) is used more frequently in the screening of high-risk populations. The purpose of our study is to segment parenchyma and to quantitatively determine volumetric breast density on pre-contrast axial DCE-MRI images (i.e., non-contrast) using a semi-automated quantitative approach. In this study, we retroactively examined 3D DCE-MRI images taken for breast cancer screening of a high-risk population. We analyzed 66 cases with ages between 28 and 76 (mean 48.8, standard deviation 10.8). DCE-MRIs were obtained on a Philips 3.0 T scanner. Our semi-automated DCE-MRI algorithm includes: (a) segmentation of breast tissue from non-breast tissue using fuzzy cmeans clustering (b) separation of dense and fatty tissues using Otsu's method, and (c) calculation of volumetric density as the ratio of dense voxels to total breast voxels. We examined the relationship between pre-contrast DCE-MRI density and clinical BI-RADS density obtained from radiology reports, and obtained a statistically significant correlation [Spearman ρ-value of 0.66 (p < 0.0001)]. Our method within precision medicine may be useful for monitoring high-risk populations.

    Hepatitis B virus (HBV) infection is a sexually transmitted infection that can be prevented with hepatitis B vaccination. The goal was to determine prevalence and risk factors for HBV infection and immunity among sexually transmitted disease (STD) clinic clients. In this cross-sectional study, consenting adult STD clinic clients were interviewed regarding HBV risk factors and vaccination history, and blood was drawn for HBV serologic testing. Of the 682 participants, 154 (22.6%) had antibody to hepatitis B core antigen, indicating previous infection, and 64 (9.4%) had only antibody to hepatitis B surface antigen, indicating immunity as a result of hepatitis B vaccination. Only 130 (19.1%) of all participants reported receiving at least one dose of hepatitis B vaccine. The majority of clients were susceptible to HBV, were at high risk for HBV infection, and would benefit from hepatitis B vaccination.

    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.

    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

    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.

  14. Pharmacological management of dyslipidemia in high and very high cardiovascular risk patients

    Full Text Available Dyslipaemia is one of the main risk factors in the development of cardiovascular diseases. Currently, there are different alternatives available (amongst which statins occupy a pre-eminent place, to optimise the treatment of patients at high or very high cardiovascular risk. Despite this, the percentage of patients that achieve good lipid control is low. The causes of the mismatch with proposed objectives include lack of patient adherence and therapeutic inertia. This review uses available evidence and the latest clinical guides as a basis to assess the pharmacological treatment of dyslipaemia in patients with a background of arteriosclerotic vascular disease, diabetes, chronic kidney disease, cardiovascular risk at ≥5% calculated by SCORE and familial hypercholesterolaemia. The treatment of hypertriglyceridemia is also reviewed along with the special consideration that poly-pharmacy deserves in patients treated with statins, making mention of the treatment of dyslipaemia with HIV infection. The global assessment of cardiovascular risk is of high priority to adapt treatment to the specific objectives of the c-LDL for each risk category.

    -protective, particularly in the case of high-risk, renally impaired populations. In"nthese randomized controlled trials conducted in the intra-arterial setting or the CT setting, the CIN incidence for iodixanol was at least as low, if not lower, than for the various low-osmolar comparators. This presentation will review the importance of identifying patients who are at-risk of CIN and will discuss strategies that can be implemented to minimize this risk and, thereby, optimize the clinical value of contemporary contrast-enhanced CT procedures.

    Low dose computed tomography (LDCT) is a viable screening tool for early lung cancer detection and mortality reduction. In practice, the success of any lung cancer screening programme will depend on successful identification of individuals at high risk in order to maximise the benefit-harm ratio. Risk prediction models incorporating multiple risk factors have been recognised as a method of identifying individuals at high risk of developing lung cancer.

    A recent international meeting was convened by two United Nations bodies to focus on international collaboration on clinical appropriateness/referral guidelines for use in medical imaging. This paper, the second of 4 from this technical meeting, addresses barriers to the successful development/deployment of clinical imaging guidelines and means of overcoming them. It reflects the discussions of the attendees, and the issues identified are treated under 7 headings: ■ Practical Strategy for Development and Deployment of Guidelines; ■ Governance Arrangements and Concerns with Deployment of Guidelines; ■ Finance, Sustainability, Reimbursement, and Related Issues; ■ Identifying Benefits and Radiation Risks from Radiological Examinations; ■ Information Given to Patients and the Public, and Consent Issues; ■ Special Concerns Related to Pregnancy; and ■ The Research Agenda. Examples of topics identified include the observation that guideline development is a global task and there is no case for continuing it as the project of the few professional organizations that have been brave enough to make the long-term commitment required. Advocacy for guidelines should include the expectations that they will facilitate: (1) better health care delivery; (2) lower cost of that delivery; with (3) reduced radiation dose and associated health risks. Radiation protection issues should not be isolated; rather, they should be integrated with the overall health care picture. The type of dose/radiation risk information to be provided with guidelines should include the uncertainty involved and advice on application of the precautionary principle with patients. This principle may be taken as an extension of the well-established medical principle of "first do no harm." Copyright © 2015. Published by Elsevier Inc.

    To report clinical characteristics of high grade foveal hypoplasia. Patients with foveal hypoplasia of grade 3 or 4 on spectral domain optical coherence tomography according to a previously published scheme were enrolled. All patients underwent a full ophthalmologic assessment including visual acuity testing, slit lamp biomicroscopy, fundus examination, and evaluation of ocular alignment. The underlying causes of foveal hypoplasia were identified as albinism in five patients and aniridia in six patients. The mean logMAR visual acuity was 0.57 ± 0.24 (range 0.22-1.00) in the right eyes and 0.58 ± 0.21 (range 0.30-1.00) in the left eyes. On fundus examination in patients with albinism, two patients showed marked transparency, one patient showed moderate transparency, and two patients showed minimal transparency. Among six patients with aniridia, five patients showed normal macular pigmentation without macular reflex and one patient showed decreased macular pigmentation with no macular reflex. Patients with high grade macular hypoplasia tended to have poor visual acuities; however, the range of visual acuity was quite variable. Other factors associated with underlying disease could be the reason of this variability. Therefore, careful consideration should be given when assessing visual prognosis in foveal hypoplasia using optical coherence tomography.

    Background: People with vascular risk factors are at increased risk for cognitive impairment as well as vascular disease. The objective of this study was to evaluate whether vascular risk factor clinical practice guidelines consider cognition as an outcome or in connection with treatment compliance. Methods: Articles from PubMed, EMBASE, and the Cochrane Library were assessed by at least two reviewers and were included if: (1) Either hypertension, high cholesterol, diabetes, or atrial fibrillation was targeted; (2) The guideline was directed at physicians; (3) Adult patients (aged 19 years or older) were targeted; and (4) The guideline was published in English. Of 91 guidelines, most were excluded because they were duplicates, older versions, or focused on single outcomes. Results: Of the 20 clinical practice guidelines that met inclusion criteria, five mentioned cognition. Of these five, four described potential treatment benefits but only two mentioned that cognition may affect compliance. No guidelines adequately described how to screen for cognitive impairment. Conclusion: Despite evidence that links cognitive impairment to vascular risk factors, only a minority of clinical practice guidelines for the treatment of vascular risk factors consider cognition as either an adverse outcome or as a factor to consider in treatment.

    Advanced therapy medicinal products (ATMPs) constitute a class of innovative products that encompasses gene therapy, somatic cell therapy, and tissue-engineered products (TEP). There is an increased investment of commercial and non-commercial sponsors in this field and a growing number of ATMPs randomized clinical trials (RCT) and patients enrolled in such trials. RCT generate data to prove the efficacy of a new therapy, but the discontinuation of RCTs wastes scarce resources. Our objective is to identify the number and characteristics of discontinued ATMPs trials in order to evaluate the rate of discontinuation. We searched for ATMPs trials conducted between 1999 to June 2015 using three databases, which are Clinicaltrials.gov, the International Clinical Trials Registry Platform (ICTRP), and the EU Drug Regulating Authorities Clinical Trials (EudraCT). We selected the ATMPs trials after elimination of the duplicates. We identified the disease areas and the sponsors as commercial or non-commercial organizations. We classified ATMPs by type and trial status, that is, ongoing, completed, terminated, discontinued, and prematurely ended. Then, we calculated the rate of discontinuation. Between 1999 and June 2015, 143 withdrawn, terminated, or prematurely ended ATMPs clinical trials were identified. Between 1999 and June 2013, 474 ongoing and completed clinical trials were identified. Therefore, the rate of discontinuation of ATMPs trials is 23.18%, similar to that for non-ATMPs drugs in development. The probability of discontinuation is, respectively, 27.35, 16.28, and 16.34% for cell therapies, gene therapies, and TEP. The highest discontinuation rate is for oncology (43%), followed by cardiology (19.2%). It is almost the same for commercial and non-commercial sponsors; therefore, the discontinuation reason may not be financially driven. No failure risk rate per development phase is available for ATMPs. The discontinuation rate may prove helpful when assessing the

    The safety of teaching off-pump coronary artery bypass grafting to trainees is best tested in high-risk patients, who are more likely to experience significant morbidity after surgery. This study compared outcomes of off-pump coronary artery bypass grafting operations performed by consultants and trainees in high-risk patients. Data for consecutive patients undergoing off-pump coronary artery bypass grafting were collected prospectively. Patients satisfying at least one of the following criteria were classified as high-risk: age older than 75 years, ejection fraction less than 0.30, myocardial infarction in the previous month, current congestive heart failure, previous cerebrovascular accident, creatinine greater than 150 micromol/L, respiratory impairment, peripheral vascular disease, previous cardiac surgery, and left main stem stenosis greater than 50%. Early morbidity, 30-day mortality, and late survival were compared. From April 1996 to December 2002, 686 high-risk patients underwent off-pump coronary artery bypass grafting revascularization. Operations by five consultants (416; 61%) and four trainees (239; 35%) were the focus of subsequent analyses. Nine visiting or research fellows performed the other 31 operations. Prognostic factors were more favorable in trainee-led operations. On average, consultants and trainees grafted the same number of vessels. There were 18 (4.3%) and 5 (1.9%) deaths within 30 days, and 14 (3.4%) and 5 (1.9%) myocardial infarctions in consultant and trainee groups, respectively. After adjusting for imbalances in prognostic factors, odd ratios for almost all adverse outcomes implied no increased risk with trainee operators, although patients operated on by trainees had longer postoperative stays and were more likely to have a red blood cell transfusion. Kaplan-Meier cumulative mortality estimates at 24-month follow-up were 10.5% (95% confidence interval, 7.7% to 14.2%) and 6.4% (95% confidence interval, 3.8% to 10.9%) in consultant

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

    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.

    Cardiovascular disease (CVD) is a major cause of disability and premature death throughout the world. Acute coronary events and other cardiovascular events frequently occur suddenly, and are often fatal before medical care can be given. Risk factor modification can reduce clinical events and premature death in people with established cardiovascular disease as well as in those who are at high cardiovascular risk due to one or more risk factors. In this work, India specific World Health Organization-International Society of Hypertension (WHO-ISH) guidelines has been implemented to stratify the subjects by their risk profile. It provides simplified approach to detect those people at high risk and provides guidance on what should be done for prevention of heart attack. Further, based on the risk stratification, lifestyle coaching, medication management and the next tests are advised to the subjects. This approach will help in early detection of cardiovascular risk subjects and provide necessary interventions at appropriate time frame. Also, it acts as motivation to the individuals to comply with recommended lifestyle changes.

    Many established breast cancer risk factors are used in clinical risk prediction models, although the proportion of breast cancers explained by these factors is unknown. To determine the population-attributable risk proportion (PARP) for breast cancer associated with clinical breast cancer risk factors among premenopausal and postmenopausal women. Case-control study with 1:10 matching on age, year of risk factor assessment, and Breast Cancer Surveillance Consortium (BCSC) registry. Risk factor data were collected prospectively from January 1, 1996, through October 31, 2012, from BCSC community-based breast imaging facilities. A total of 18 437 women with invasive breast cancer or ductal carcinoma in situ were enrolled as cases and matched to 184 309 women without breast cancer, with a total of 58 146 premenopausal and 144 600 postmenopausal women enrolled in the study. Breast Imaging Reporting and Data System (BI-RADS) breast density (heterogeneously or extremely dense vs scattered fibroglandular densities), first-degree family history of breast cancer, body mass index (>25 vs 18.5-25), history of benign breast biopsy, and nulliparity or age at first birth (≥30 years vs breast cancer. Of the 18 437 women with breast cancer, the mean (SD) age was 46.3 (3.7) years among premenopausal women and 61.7 (7.2) years among the postmenopausal women. Overall, 4747 (89.8%) premenopausal and 12 502 (95.1%) postmenopausal women with breast cancer had at least 1 breast cancer risk factor. The combined PARP of all risk factors was 52.7% (95% CI, 49.1%-56.3%) among premenopausal women and 54.7% (95% CI, 46.5%-54.7%) among postmenopausal women. Breast density was the most prevalent risk factor for both premenopausal and postmenopausal women and had the largest effect on the PARP; 39.3% (95% CI, 36.6%-42.0%) of premenopausal and 26.2% (95% CI, 24.4%-28.0%) of postmenopausal breast cancers could potentially be averted if all women with heterogeneously or extremely dense

    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.

    Full Text Available Objectives: to stratify the risk for obstructive sleep apnea in patients with acute myocardial infarction, treated at a public, tertiary, teaching hospital of the state of São Paulo, Brazil, and to identify related sociodemographic and clinical factors.Method: cross-sectional analytical study with 113 patients (mean age 59.57 years, 70.8% male. A specific questionnaire was used for the sociodemographic and clinical characterization and the Berlin Questionnaire for the stratification of the risk of obstructive sleep apnea syndrome.Results: the prevalence of high risk was 60.2% and the outcome of clinical worsening during hospitalization was more frequent among these patients. The factors related to high risk were body mass index over 30 kg/m2, arterial hypertension and waist circumference indicative of cardiovascular risk, while older age (60 years and over constituted a protective factor.Conclusion: considering the high prevalence of obstructive sleep apnea and its relation to clinical worsening, it is suggested that nurses should monitor, in their clinical practice, people at high risk for this syndrome, guiding control measures of modifiable factors and aiming to prevent the associated complications, including worsening of cardiovascular diseases.

    Full Text Available Despite treatment with radical cystectomy and pelvic lymph node dissection, muscle invasive bladder cancer has a relapse rate of 50%. Patients can develop regionally advanced or metastatic disease that ultimately leads to death. The addition of neoadjuvant or adjuvant chemotherapy to reduce the risk of relapse and death has been extensively studied over the past two decades. Two contemporary trials coupled with a recent meta-analysis evaluating neoadjuvant chemotherapy demonstrated a modest but real improvement in overall survival. This has made neoadjuvant chemotherapy a standard of care. Clinical trials evaluating adjuvant chemotherapy in patients with high-risk disease have been plagued with statistical flaws and have, therefore, been unable to define the survival impact of this approach. It is hoped that ongoing adjuvant trials that are powered to detect small but meaningful clinical differences will clarify the benefit of chemotherapy after cystectomy. Since there are theoretical advantages and disadvantages to each of these approaches, both are widely used in North America. The evidence behind each approach and potential future developments in this field will be described.

The evidence behind each approach and potential future developments in this field will be described.

    Older patients who are at risk of poor healthcare outcomes should be recognised early during hospital admission to allow appropriate interventions. It is unclear whether routinely collected data can identify high-risk patients. The aim of this study was to define current practice with regard to the identification of older patients at high risk of poor healthcare outcomes on admission to hospital. Interviews/focus groups were conducted to establish the views of 22 healthcare staff across five acute medicine for older people wards in one hospital including seven nurses, four dieticians, seven doctors, and four therapists. In addition, a random sample of 60 patients' clinical records were reviewed to characterise the older patients, identify risk assessments performed routinely on admission, and describe usual care. We found that staff relied on their clinical judgment to identify high risk patients which was influenced by a number of factors such as reasons for admission, staff familiarity with patients, patients' general condition, visible frailty, and patients' ability to manage at home. "Therapy assessment" and patients' engagement with therapy were also reported to be important in recognising high-risk patients. However, staff recognised that making clinical judgments was often difficult and that it might occur several days after admission potentially delaying specific interventions. Routine risk assessments carried out on admission to identify single healthcare needs included risk of malnutrition (completed for 85% patients), falls risk (95%), moving and handling assessments (85%), and pressure ulcer risk assessments (88%). These were not used collectively to highlight patients at risk of poor healthcare outcomes. Thus, patients at risk of poor healthcare outcomes were not explicitly identified on admission using routinely collected data. There is a need for an early identification of these patients using a valid measure alongside staff clinical judgment to

    In clinical trials, the reduction of LDL-cholesterol (LDL-C) with statins reduces the incidence rate of cardiovascular events by approximately one third. This means, that a sizeable "residual risk" remains. Besides high lipoprotein (a), disorders in the metabolism of triglyceride-rich lipoproteins and high density liproteins have been implicated as effectors of the residual risk. Both lipoprotein parameters correlate inversely with each other. Therefore, the etiological contributions of triglycerides and / or of HDL for developing cardiovascular disease can hardly be estimated from either observational studies or from intervention studies. The largely disappointing results of intervention studies with inhibitors of the cholesteryl ester transfer protein and in particular the available set of genetically-epidemiological studies suggest that in the last decade, the importance of HDL cholesterol has been overvalued, while the importance of triglycerides has been underestimated. High triglycerides not always atherogenic, but only if they are associated with the accumulation relatively cholesterol-enriched, incompletely catabolized remnants of chylomicrons and very low density lipoproteins (familial type III hyperlipidemia, metabolic syndrome, diabetes mellitus). The normalization of the concentration of triglycerides and remnants by inhibiting the expression of apolipoprotein C3 is hence a new, promising therapeutic target.

    Next generation sequencing is a transformative technology for discovering and diagnosing genetic disorders. However, high-throughput sequencing remains error-prone, necessitating variant confirmation in order to meet the exacting demands of clinical diagnostic sequencing. To address this, we devised an orthogonal, dual platform approach employing complementary target capture and sequencing chemistries to improve speed and accuracy of variant calls at a genomic scale. We combined DNA selection by bait-based hybridization followed by Illumina NextSeq reversible terminator sequencing with DNA selection by amplification followed by Ion Proton semiconductor sequencing. This approach yields genomic scale orthogonal confirmation of ~95% of exome variants. Overall variant sensitivity improves as each method covers thousands of coding exons missed by the other. We conclude that orthogonal NGS offers improvements in variant calling sensitivity when two platforms are used, better specificity for variants identified on both platforms, and greatly reduces the time and expense of Sanger follow-up, thus enabling physicians to act on genomic results more quickly.

    Chronic respiratory diseases (CRDs) are a heterogeneous group of diseases that can affect the pediatric population and health authorities throughout the world recommend influenza vaccination because of the significant risk of influenza-related complications. However, despite this recommendation, vaccine coverage is generally unsatisfactory. The aim of this review is to analyze the impact of influenza on children at high risk of respiratory disease, and the immunogenicity, safety and efficacy of influenza vaccination in such children. The results show that there is a significant risk of influenza-related complications in preterm neonates and infants, in whom influenza vaccines are immunogenic and safe (although their efficacy has not been specifically studied). There are conflicting data concerning the effect of influenza infection on asthma morbidity in children, and whether or not influenza vaccination helps to prevent asthma exacerbations. Recent data provide no evidence that influenza is more frequent in patients with cystic fibrosis than in healthy subjects, or that it is responsible for increased lower respiratory tract morbidity. The lack of any clear correlate of protection suggests that future studies should also consider the efficacy of the different influenza vaccines and not only evaluate them in terms of immunogenicity. Furthermore, there is a need for clinical studies to assess the effectiveness of the available vaccines in patients with other rare CRDs and other chronic underlying diseases with possibly severe respiratory involvement. It is also important to determine whether children with recurrent respiratory tract infections should be included in the list of those for whom influenza vaccination is recommended. In the meantime, given the increasing evidence of the burden of influenza on the population as a whole and the benefits associated with vaccination, annual influenza vaccinations should be recommended for all children at high risk of

    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.

    1990-01-01

    Cancer risk analysis is a relatively new clinical service that has developed as more precise information has become available regarding specific risk factors. Both epidemiological and genetic factors contribute substantially to the identification of women at higher risk for developing breast cancer. The definition of what constitutes risk, an understanding of which factors influence risk, and the ability to present risk information clearly are critical features. In addition to providing information about risk and assessing each woman's perception of risk, the emotional issues must be addressed. The focus of intervention should center upon the benefits of early detection, assessment of breast self-examination skills, individualized breast cancer screening recommendations, such as mammography and physical exams, and recommendations for life style changes for possible prevention.

    The cornea is the most commonly transplanted tissue in the body. Although corneal grafts generally have high success rates, transplantation onto inflamed and vascularized host beds, or so-called high-risk corneal transplantation, has a high rate of graft rejection. The management of this high-risk corneal transplantation is challenging and involves numerous measures. One of the key measures to prevent graft rejection in these cases is the use of systemic immunosuppressive agents. In this article, we will review the systemic immunosuppressive agents most commonly used for high-risk corneal transplantation, which include corticosteroids, cysclosporine A, tacrolimus, mycophenolate mofetil, and rapamycin. Benefits, risks, and published data on the use of these medications for high-risk corneal transplantation will be detailed. We will also summarize novel immunoregulatory approaches that may be used to prevent graft rejection in high-risk corneal transplantation.

    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.

    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.

    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.

    Full Text Available Objective: To investigate the speech therapy procedures performed in a neonatal ICU. Methods: A documental research based on registration records, comprised by a total of 34 newborns that required early stimulation by the speech therapy service in a neonatal ICU of a hospital with tertiary level of care. The study was held in the period between August, 2005 and January, 2006. From the sample, 14 children were female (41.2% and 20 were male (58.8%. The age of the newborns ranged from 3 to 57 life days. The studied variables included: risk conditions of the newborn, clinical assessment procedures, the intervention performed and the results obtained regarding weight. Results: The risk condition of preterm newborn (PTNB associated with respiratory distress syndrome (RDS was present in 25 (73.5% children. The initial weight of 15 (44.11% children ranged from 1170 to 1742 grams. The most widely discussed speech therapy procedures were the assessment of oral functions with identification of changes in sucking and swallowing in 25 (73.5% newborns and intervention by means of non-nutritive sucking in 18 (53% children. At the end of speech therapy, 19 (55.9% children weighed between 1742 to 2314 grams. Conclusions:The benefits of speech therapy performance were related to the identification of high-risk children who required intervention in oral functions and organization of the baby for feeding. It is assumed that the introduction of oral administration as quickly and safely as possible favored the improvement of the nutritional status of children and their clinical evolution

    To determine the prevalence of registered trials and to evaluate the risk of bias between registered and unregistered clinical trials. The Cochrane Gynecology and Fertility Group's specialized register was searched on November 5, 2015, for randomized controlled trials published from 2010 to 2014. Studies were selected if they had randomized women or men for fertility treatments, were published in full text and written in English. Two reviewers then independently assessed trial registration status for each trial, by searching the publication, trial registries, and by contacting the original authors. Of 693 eligible randomized controlled trials, only 44% were found to be registered. Unregistered clinical trials had smaller sample sizes than registered trials (P risk of bias using five of the Cochrane Risk of Bias "domains." Registered and unregistered trials differed in their risk of bias for random sequence generation (P = 0.001), allocation concealment (P = 0.003), and selective reporting (P  0.05) domains. Only 54 (43.2%) of the 125 registered trials were registered prospectively. This study has the following limitations. Only English language trials were included in this review. We were unable to obtain protocols for the unregistered trials and therefore were unable to assess the risk of bias in the selective reporting domain. All available trials should be included in systematic reviews and assessed for risk of bias as there are both registered trials with high risk of bias and unregistered trials with low risk of bias and by excluding unregistered trials more than half of the available evidence will be lost.

WBC<4×109/L was found in 24 cases. There were 50 cases with positive serum CRP. Single factor analysis of logistic infor-mation between the two groups showed that PH, BE, blood pressure, urine output, mechanical ventilation, shock score, multi-ple organ failure were risk factors affecting the prognosis. Multiple factors regression analysis showed BE , shock score and mul-tiple organ failure were independent risk factors for poor prognosis. Conclusion The mortality of neonatal septic shock re-mains at a high level, and the shock tends to occur before the blood pressure step-down. Severe acidosis, high shock score, and multiple organ failure should be regarded as the independent risk factors for poor prognosis. The more organs involved , the higher the death rate occurred.

    Full Text Available Abstract Background The percentage of hypertrophic cardiomyopathy (HCM patients who are in high risk for Sudden Death (SD constitutes only a minority of all HCM population but the incidence of SD in this subset is high (at least 5% annually. The identification of this small but important proportion of high risk HCM patients has been the clue in the clinical evaluation of these patients. Methods Our study cohort consisted from 123 patients with HCM who are currently followed up in our Institution. Five clinical risk factors were assessed: a family history of premature SD, unexplained syncope, Non Sustained Ventricular Tachycardia (NSVT on 24-h ECG monitoring, Abnormal Blood Pressure Response (ABPR during upright exercise testing and Maximum left ventricular Wall Thickness (MWT ≥30 mm. The purpose of our study was the identification of high risk HCM patients coming from Northern Greece. Results Fifteen patients (12.2% of the whole cohort had MWT ≥ 30 mm, 30 patients (24.4% had an ABPR to exercise, 17 patients (13.8% had episodes of NSVT in 24-h Holter monitoring, 17 patients (13.8% suffered from syncope, and 8 patients (6.5% had a positive family history of premature SD. Data analysis revealed that 74 patients (60.1% had none risk factor. Twenty four patients (19.5% had 1 risk factor, 17 patients (13.8% had 2 risk factors, 4 patients (3.25% had 3 risk factors, and 4 patients (3.25% had 4 risk factors, while none patient had 5 risk factors. Twenty five patients (20.3% had 2 or more risk factors. Conclusion This study for the first time confirms that, although a 60% of patients with HCM coming from a regional Greek population are in low risk for SD, a substantial proportion (almost 20% carries a high risk for SD justifying prophylactic therapy with amiodaron or ICD implantation.

    To demonstrate the patterns of breast cancer-specific mortality (BCSM) in estrogen receptor (ER)-positive diseases and to identify high-risk candidates for extended endocrine therapy. Using the Surveillance, Epidemiology and End Results database, we identified ER-positive patients diagnosed between 1990 and 2000 (cohort 1 [C1]) and between 2001 and 2005 (cohort 2 [C2]). The patterns of BCSM were calculated using Cox proportional hazard regression models. A risk classification model was developed, and X-tile software was used to divide patients with high BCSM rates into 3 risk groups. The annual BCSM rate of C2 was decreased by one-third and was maintained at 10-15 (per 1000 persons per year) from year 2 to year 10. Long-term mortality risks still persisted in C2, especially in patients with node-positive, grade 3 or T3 disease, who should be considered as "clinical-high-risk". These patients were further divided into 3 risk groups through our model: for C1, 42.2% were in the low-risk group, 38.9% in the medium-risk group, and 18.9% in the high-risk group; and for C2, 45.5% were in the low-risk group, 38.2% in the medium-risk group and 16.2% in the high-risk group (p risk group. ER-positive patients with node-positive, grade 3 or T3 diseases had sustained risks of death throughout the 10-year time frame, and our model is helpful to identify patients with high risk who are candidates for extended endocrine therapy.

    Neurogenic lower urinary tract dysfunction (NLUTD) is very common in patients with multiple sclerosis (MS), and it might jeopardize renal function and thereby increase mortality. Although there are well-known urodynamic risk factors for upper urinary tract damage, no clinical prediction parameters are available. We aimed to assess clinical parameters potentially predicting urodynamic risk factors for upper urinary tract damage. A consecutive series of 141 patients with MS referred from neurologists for primary neuro-urological work-up including urodynamics were prospectively evaluated. Clinical parameters taken into account were age, sex, duration, and clinical course of MS and Expanded Disability Status Scale (EDSS). Multivariate modeling revealed EDSS as a clinical parameter significantly associated with urodynamic risk factors for upper urinary tract damage (odds ratio = 1.34, 95% confidence interval (CI) = 1.06-1.71, p = 0.02). Using receiver operator characteristic (ROC) curves, an EDSS of 5.0 as cutoff showed a sensitivity of 86%-87% and a specificity of 52% for at least one urodynamic risk factor for upper urinary tract damage. High EDSS is significantly associated with urodynamic risk factors for upper urinary tract damage and allows a risk-dependent stratification in daily neurological clinical practice to identify MS patients requiring further neuro-urological assessment and treatment.

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    Standard dosing of chemotherapy based on body surface area results in marked interpatient variation in pharmacokinetics, toxic effects, and efficacy. Whether tailored dosing can improve outcomes is unknown, as is the role of dose-dense adjuvant chemotherapy. To determine whether tailored dose-dense adjuvant chemotherapy improves the outcomes of early breast cancer compared with a standard 3-weekly chemotherapy schedule. A randomized, open-label, phase 3 trial of women aged 65 years and younger who had surgery for nonmetastatic node-positive or high-risk node-negative breast cancer at 86 sites in Sweden, Germany, and Austria between February 20, 2007, and September 14, 2011. Patients were randomized 1:1 either to 4 cycles of leukocyte nadir-based tailored and dose-dense adjuvant epirubicin and cyclophosphamide every 2 weeks followed by 4 cycles of tailored dose-dense docetaxel every 2 weeks, or to standard-interval chemotherapy with 3 cycles of fluorouracil and epirubicin-cyclophosphamide every 3 weeks followed by 3 cycles of docetaxel every 3 weeks. The primary end point was breast cancer recurrence-free survival (BCRFS). Secondary end points included 5-year event-free survival (EFS), distant disease-free survival (DDFS), overall survival (OS), and rates of grade 3 or 4 toxic effects. Among 2017 randomized patients (1006 in the tailored dose-dense group and 1011 in the control group; median [IQR] age, 51 [45-58] years; 80% with hormone receptor-positive tumors; 97% with node-positive disease), 2000 received study treatment (≥1 cycle of chemotherapy; 1001 in the tailored dose-dense group and 999 in the control group). After a median follow-up of 5.3 years (IQR, 4.5-6.1 years), 269 BCRFS events were reported, 118 in the tailored dose-dense group and 151 in the control group (HR, 0.79; 95% CI, 0.61-1.01; log-rank P = .06; 5-year BCRFS, 88.7% vs 85.0%). The tailored dose-dense group had significantly better EFS than the control group (HR, 0.79; 95% CI, 0

    Rheumatologists are increasingly involved in the care of young women who, in the age of biologic therapy, are now gaining control of their rheumatic diseases and attempting pregnancy. With careful planning, most women with rheumatic diseases have successful pregnancies. This article focuses specifically on the highest-risk pregnancies and controversial areas. We discuss the women at risk of complications, the types of maternal and fetal complications, the treatments that can be used in pregnancy (and breastfeeding) and longer-term outcomes that could affect the mother. SLE, RA, ANCA-associated vasculitides, large vessel vasculitis (e.g. Takayasu's) and other CTDs (e.g. scleroderma) are among the conditions covered. The evidence and controversies regarding the recommendations for the use of biologics in pregnancy are discussed. The role of the rheumatologist in pregnancy planning and caring for the pregnant and post-partum woman as part of the multidisciplinary team is discussed.

    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.

    Cardiac troponin assays have an established and undisputed role in the diagnosis and risk stratification of patients with acute myocardial infarction. As troponin assays gets more sensitive and more precise, the number of potential uses has rapidly expanded, but the use of this test has also become more complicated and controversial. Highly sensitive troponin assays can now detect troponin levels in most individuals, but accurate interpretation of these levels requires a clear understanding of the assay in the context of the clinical scenario. This paper provides a practical and up-to-date overview of the uses of highly sensitive troponin assays for diagnosis, prognosis, and risk stratification in clinical practice.

    China is currently experiencing one of the most rapidly expanding HIV epidemics in the world. Although the overall prevalence rate is still low, with a population of 1.3 billion, high-risk factors which have contributed to the HIV/AIDS epidemics worldwide continue to prevail in China, including a high rate of injecting drug use and needle sharing,commercial sex with low rates of condom use, and concurrent sex with both commercial sex workers and noncommercial casual or steady sex partners. In addition, there are increasing "double risk" populations overlapping drug users and sex workers, as well as increasing rates of STDs and HIV among high-risk populations. Sexual transmission,therefore, may serve as a bridge connecting high-risk populations with general populations. There is an urgent need to prevent the spread of HIV from these high-risk populations into the general population of China.

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

  5. Patients at High-Risk for Surgical Site Infection.

    Mueck, Krislynn M; Kao, Lillian S

    Surgical site infections (SSIs) are a significant healthcare quality issue, resulting in increased morbidity, disability, length of stay, resource utilization, and costs. Identification of high-risk patients may improve pre-operative counseling, inform resource utilization, and allow modifications in peri-operative management to optimize outcomes. Review of the pertinent English-language literature. High-risk surgical patients may be identified on the basis of individual risk factors or combinations of factors. In particular, statistical models and risk calculators may be useful in predicting infectious risks, both in general and for SSIs. These models differ in the number of variables; inclusion of pre-operative, intra-operative, or post-operative variables; ease of calculation; and specificity for particular procedures. Furthermore, the models differ in their accuracy in stratifying risk. Biomarkers may be a promising way to identify patients at high risk of infectious complications. Although multiple strategies exist for identifying surgical patients at high risk for SSIs, no one strategy is superior for all patients. Further efforts are necessary to determine if risk stratification in combination with risk modification can reduce SSIs in these patient populations.

    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.

    Persistent cervical high-risk human papillomavirus (HPV) infection is correlated with an increased risk of developing a high-grade cervical intraepithelial lesion. A two-step method was developed for detection and genotyping of high-risk HPV. DNA was firstly amplified by asymmetrical PCR in the presence of Cy3-labelled primers and dUTP. Labelled DNA was then genotyped using DNA microarray hybridization. The current study evaluated the technical efficacy of laboratory-designed HPV DNA microarrays for high-risk HPV genotyping on 57 malignant and non-malignant cervical smears. The approach was evaluated for a broad range of cytological samples: high-grade squamous intraepithelial lesions (HSIL), low-grade squamous intraepithelial lesions (LSIL) and atypical squamous cells of high-grade (ASC-H). High-risk HPV was also detected in six atypical squamous cells of undetermined significance (ASC-US) samples; among them only one cervical specimen was found uninfected, associated with no histological lesion. The HPV oligonucleotide DNA microarray genotyping detected 36 infections with a single high-risk HPV type and 5 multiple infections with several high-risk types. Taken together, these results demonstrate the sensitivity and specificity of the HPV DNA microarray approach. This approach could improve clinical management of patients with cervical cytological abnormalities.

    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.)

    Chagas disease is a parasite infection caused by the protozoan Trypanosoma cruzi. Its most common complications is chronic Chagas heart disease but impairments of the systemic vasculature also has been observed. Although the different mechanisms that regulate blood pressure are disrupted, to our knowledge data on the association of hypertension and chronic Chagas disease are scarce. In this regard we evaluate whether Chagas disease constitutes a high blood pressure risk factor. We recruited 200 individuals, half of them with positive serology for T. cruzi. They were subjected to a complete clinical examination. The mean age of sampled individuals was 46.7 ± 12.3, and the mean of systolic and diastolic blood pressure were 124 ± 12 mmHg and 82 ± 10 mmHg, respectively. There were no between-group differences regarding age, sex distribution or body mass index. Chagas disease contributed significantly to high blood pressure (OR = 4, 95% CI 1.8323-7.0864, p = 0.0002). Our results reveal an important association between Chagas disease and high blood pressure, which should be contemplated by physicians in order to promote preventive cardiovascular actions in patients with Chagas disease.

    Concerns exist that some uses of antimicrobials in cattle may lead to the emergence, proliferation, dissemination and persistence of resistant pathogenic bacteria in animal agriculture, which in turn can infect humans via the food supply. The degree of perceived risk varies with the clinical indication for which the antimicrobial in question is used. In this study, four uses of antimicrobials are considered, including in acutely sick, chronically sick, at-risk, and high-risk cattle, contrasting the degree of risk among these uses. Using a random sample of 103 feedlot cattle veterinarians and variables drawn from the theory of planned behavior, we predict differences in risk perception by clinical indication with differences in perceived efficacy of antimicrobials, social pressures to use antimicrobials, and moral obligations to use antimicrobials. In most models, veterinarians who perceived that others in the feedlot industry (i.e., other feedlot veterinarians, nutritionists, feedlot clients, and retained owners of cattle) were more likely to expect them to use antimicrobials in one situation versus another, the less likely those veterinarians perceived the risk of antimicrobial risk to be greater in the former versus the latter situation. Only two of these contrasts contained influences outside the immediate feedlot relationships. This exception involves the 'downstream' public: meat packers, retailers, and consumers. Veterinarians who believe that using antimicrobials for acutely sick cattle is more beneficial than using antimicrobials for chronically sick cattle were more likely to believe that antimicrobial resistance was a less probable outcome in acutely sick cattle than in chronically sick cattle.

    Purpose To evaluate the prevalence and type distribution of high-risk human papillomavirus (HPV) infection in genital warts of Korean men, and for the first time, to describe the risk factors associated with high-risk HPV infection in male genital warts. Materials and Methods In a single private clinic, 150 consecutive male patients with histopathologic-confirmed genital warts who underwent HPV genotyping by use of polymerase chain reaction (PCR) were included in this study. We detected HPV DNA in male genital warts and evaluated HPV type distribution, especially high-risk HPV types, by use of PCR. The associations between HPV prevalence and various characteristics, such as age, circumcision status, type of genital warts diagnosis (new vs. recurrent), number of lesions, site of lesions, and gross morphology, were assessed by use of unconditional multiple logistic regression. Results High-risk HPV types were detected in 31 cases (23.5%), and of these, 27 cases (20.5%) contained both high-risk and low-risk HPV types. The most frequently detected high-risk HPV types were HPV16 (6.8%), HPV33 (4.5%), HPV18 (2.3%), and HPV68 (2.3%). In particular, the prevalence of infection with HPV16 and/or HPV18 was 8.3% (11 of 132). In the multivariate analysis, lesions located at sites including the base of the penis or the pubic area, papular or mixed genital warts, and lack of circumcision significantly increased the association with high-risk HPV infection in male genital warts. Conclusions The prevalence of high-risk HPV infection was substantial in male genital warts. The site and morphology of lesions and circumcision status were significantly associated with the prevalence of high-risk HPV infection. PMID:24648877

    Deep-vein thrombosis (DVT) represents a serious complication in acute stroke patients with pulmonary embolus (PE) as a potential outcome. Prediction of DVT may help with formulating a proper prevention strategy. To assess of the risk of deep venous thrombosis (DVT) in acute stroke patients, we developed and validated a clinical score in a cohort study. Incidence of Deep Venous Thrombosis after Acute Stroke in China (INVENT-China) is a multicenter prospective cohort study. The potential predictive variables for DVT at baseline were collected, and the presence of DVT was evaluated using ultrasonography on the 14 ± 3 days. Data were randomly assigned to either a training data set or a test data set. Multivariate logistic regression analysis was used to develop risk scores to predict DVT in the training data set and the area under the receiver operating characteristic curve to validate the score in the test data set. From 2006-2007, 862 hospital-based acute stroke patients were enrolled in China. The overall incidence of DVT after acute stroke within two weeks was 12.4% (95%CI 10.3-14.7%). A seven-point score derived in the training data set (age [≥65 years = 1], sex [female gender = 1]), obesity [BMI ≥ 25 kg/m(2) = 1], active cancer [yes = 2], stroke subtype [cerebral hemorraghe = 1], muscle weakness [≥2 on Lower limb NIHSS score = 1] was highly predictive of 14-day risk of DVT(c statistic = 0.70, 95% CI, 0.64-0.76, P < 0.001), in the overall study population(c statistic = 0.65, 95% CI 0.59-0.70, P < 0.001). This clinical score may help identify acute stroke patients with high risk of DVT. In addition, it also serves as a platform to develop further models of DVT prediction in stroke patients based on clinical factors. © 2014 John Wiley & Sons Ltd.

    The aim of the current study was to test the effectiveness of a physical activity and exercise-based program in a clinical context to reduce cardiovascular risk factors in children and adolescents. A randomized clinical trial was conducted in a pediatric preventive outpatient clinic. Intervention was 14 weeks of exercise for the intervention group or general health advice for the control group. The primary and the secondary outcomes were reduction of cardiovascular risk factors and the feasibility and the effectiveness of clinical advice plan to practice physical exercises at home. A total of 134 children were screened; 26 met eligibility criteria. Of these, 10 were allocated in the exercise intervention group and nine were included in the control group until the end of the intervention. Those patients who discontinued the intervention had the lowest scores of z-BMI (P = 0.033) and subscapular skin fold (P = 0.048). After 14 weeks of intervention, no statistical differences were found between the groups. High-density lipoprotein cholesterol (HDL-C) was higher in the exercise group, with a mild tendency to be significant (P = 0.066). Patients who adhere to treatment had diastolic blood pressure decreased from baseline to the end of the follow-up period in the control group (P = 0.013). Regardless of this result, the other comparisons within the group were not statistically different between T0 and T14. A low-cost physical activity advice intervention presented many barriers for implementation in routine clinical care, limiting its feasibility and evaluation of effectiveness to reduce cardiovascular risk factors.

    Full Text Available Cardiovascular disease (CVD risk factors, such as diabetes, hypertension, hypercholesterolemia, smoking, and obesity tend to occur together in the general population. Increasing prevalence of multiple CVD risk factors has been related to increased risk of death from coronary heart disease and stroke. Studies have suggested that people with several risk factors of CVD may have impaired health-related quality of life. The objective of this study was to assess the association of CVD risk factors with quality of life (QOL among adults aged 40 to 65 years. A cross-sectional study was conducted involving 220 subjects 40 - 65 years of age at a health center. The CVD risk factors were assessed using the Framingham risk score that is the standard instrument for assessment of the risk of a first cardiac event. The risk factors assessed were age, smoking, blood pressure, total cholesterol and high density lipoprotein cholesterol concentrations. QOL was assessed by means of the WHOQOL-BREF instrument that had been prevalidated. The results of the study showed that 28.2% of subjects were smokers, 56.4% had stage 1 hypertension, 42.8% high total cholesterol and 13.6% low HDL cholesterol. The high risk group amounted to 45.5% and 42.3% constitued an intermediate risk group. High CVD risk scores were significantly associated with a low QOL for all domains (physical, psychological, social and environment (p=0.000. Preventing or reducing the multiple CVD risk factors to improve QOL is necessary among adults.

    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).

    Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

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

    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.

    Few reports of delirium-related risk factors have focused on environmental risk factors and clinical risk factors, such as white matter signal abnormalities on magnetic resonance imaging fluid attenuated inversion recovery images. We prospectively enrolled 253 patients admitted to our neurosurgical center between December 2014 and June 2015 and analyzed 220 patients (100 male patients; mean age, 64.1 years; age range, 17-92 years). An Intensive Care Delirium Screening Checklist score ≥4 points indicated delirium. We evaluated patient factors consisting of baseline characteristics and related factors, such as white matter lesions (WMLs), as well as the surrounding environment. Delirium occurred in 29/220 cases (13.2%). Regarding baseline characteristics, there were significant statistical correlations between delirium and age (P = 0.0187), Hasegawa Dementia Scale-Revised score (P = 0.0022) on admission, and WMLs (P delirium and stay in a neurosurgical care unit (P = 0.0245). Multivariate logistic regression analyses showed statistically significant correlations of delirium with WMLs (P delirium (P = 0.026). WMLs in patients and the surrounding environment are risk factors for delirium in a neurosurgical center. To prevent delirium, clinicians must recognize risk factors, such as high-grade WMLs, and manage environmental factors. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Teenagers are believed the people who are supposed to build the world's future. High-risk behaviors such as addiction to drugs, smoking cigarettes, sex, etc. could significantly hurts teenagers and there must be some supporting programs to reduce these issues as much as possible. This paper performs an empirical investigation to study the different factors influencing high- risk behavior among teenagers who live in a city of Esfahan, Iran. The proposed study designs a questionnaire and distribute between two groups of female and male teenagers. The results indicate that while there is a meaningful relationship between high-risk behaviors and average high school marks among male students there is no meaningful relationship between high-risk behaviors and high school grades among female students. The results also indicate that there is a meaningful difference between gender and high-risk behavior. The season of birth for female and male students is another important factor for having high-risk behaviors. While the order of birth plays an important role among male students, the order of birth is not an important factor among female teenagers. Finally, the results indicate that teenagers' parental financial affordability plays a vital role on both female and male teenagers.

    Humphreys, Kathryn L; Lee, Steve S; Tottenham, Nim

    2013-04-01

    Risk taking behavior can be both adaptive and maladaptive depending on context. The majority of studies of risk taking, however, focus on clinical populations and dangerous or harmful risk taking. Individual differences in learning during risk taking are rarely examined in relation to task performance. The present study examined risk taking and associated outcomes in an exploration-based instrumental learning task (Balloon Emotional Learning Task; BELT), which presented a series of balloons in which participants pump up for points. Consistent with prior work, sensation seeking predicted increased risk taking behavior. Importantly, however, a significant interaction between sensation seeking and associative sensitivity, an attentional construct defined as the frequency and remoteness of automatic cognitive activity, was found. Specifically, among individuals high in sensation seeking, associative sensitivity predicted fewer balloon explosions and an increase in points earned on the balloon condition with the most potential feedback driven learning. Thus, these findings suggest that sensation seekers are a heterogeneous group, and secondary traits such as associative sensitivity moderate behavior such as risk taking and learning according to context.

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

    Directory of Open Access Journals (Sweden)

    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.

    After the 1990 establishment of a multidisciplinary foot salvage clinic, 1346 diabetic patients, at high risk for the development of foot ulcers and eventual lower limb amputation, were followed for 4 years. Of the 224 high-risk patients admitted to the hospital, 74 amputations (5.5%) of all or part of a lower limb were performed. Patients undergoing amputation were younger, more severely ill, and required more frequent hospitalizations because of greater organ system involvement. They were also more likely to be institutionalized after discharge. Overall, patients with long-standing adult-onset diabetes, identified as at high risk for foot ulcer development, have a substantially increased risk for lower limb amputation, multiple organ system failure, hospitalization, and institutionalization than do diabetic patients as a whole. Clinical benchmarking facilitates the identification and reduction of unnecessary variations in patient care practices. Here, a formal benchmark analysis provides the current outcome expectations for amputation rates and co-morbidities in patients with diabetes who are classified as at high risk for lower extremity amputation. Management of these patients in a structured, multidisciplinary foot salvage clinic, augmentation of baseline services, and preliminary benchmark data may provide a standard for the measurement of therapeutic interventions that improve patient care.

    Because of the improvements in survival rates, patients with breast cancer are now more likely to die from cardiovascular disease than from cancer. Thus, providing appropriate preventive cardiovascular care to patients with cancer is of the utmost importance. We retrospectively compared the cardiovascular risk and management of 146 women treated at the Cardio-Oncology (Cardio-Onc) and the Obstetrics and Gynecology (Ob-Gyn) clinics. We calculated cardiovascular risk using the American College of Cardiology (ACC)/American Heart Association (AHA) atherosclerotic cardiovascular disease (ASCVD) risk calculator and the Framingham Risk Score Calculator. We also determined the prevalence of appropriate statin use according to both the 2013 ACC/AHA and the 2002 Adult Treatment Panel (ATP) III lipid guidelines. The 10-year ASCVD risk score was not significantly different between the 2 cohorts. More patients in the Ob-Gyn cohort with an ASCVD risk score >7.5% were already appropriately on statins compared to patients in the Cardio-Onc cohort (60.9% vs 31.0%, respectively, P=0.003), but after the first Cardio-Onc visit, 4 additional patients with breast cancer were prescribed statins (44.8% total). Fourteen (19.2%) Cardio-Onc patients had a high Framingham Risk Score compared to 6 (8.2%) Ob-Gyn patients. We demonstrated that the ASCVD risk is similar between women with breast cancer attending the Cardio-Onc clinic and the women without breast cancer attending the Ob-Gyn clinic, but the Cardio-Onc cohort had significantly more patients with a high Framingham Risk Score. Both clinics had similarly poor rates of appropriate statin prescribing rates according to the ATP III guidelines.

    Abstract Metabolic abnormalities are common in patients with depressive disorders. However, the relationship between gout and depression is unclear. We explored the causal relationship among gout, antigout medication, and the associated risk of incidental depressive disorders. In this nationwide cohort study, we sampled data from the National Health Insurance Research Database to recruit 34,050 patients with gout as the gout cohort and 68,100 controls (without gout) as the nongout cohort. Our primary endpoint was the diagnosis of depressive disorders during follow-up. The overall study population was followed up until depression diagnosis, withdrawal from the NHI program, or the end of the study. The differences in demographic and clinical characteristics between both cohorts were determined using the Chi-square test for categorical variables and the t-test for continuous variables. Cox proportional hazard regression models were used to examine the effect of gout on the risk of depression, represented using the hazard ratio with the 95% confidence interval. Patients with gout exhibited a higher risk of depressive disorders than controls did. The risk of depressive disorders increased with age and was higher in female patients and those with hypertension, stroke, and coronary artery disease. Nonsteroidal antiinflammatory drug and prednisolone use was associated with a reduced risk of depression. Patients with gout who had received antigout medication exhibited a reduced risk of depressive disorders compared with nongout patients. Our findings support that gout increases the risk of depressive disorders, and that antigout medication use reduces the risk. PMID:26717394

    Full Text Available In this article, we summarise research that identifies best practice for communicating about hazards where the risk is low but public concern is high. We apply Peter Sandman’s ‘risk = hazard + outrage’ formulation to these risks, and review factors associated with the amplification of risk signals. We discuss the structures that determine the success of risk communication strategies, such as the capacity for early communication to ‘capture’ the dominant representation of risk issues, the importance of communicating uncertainty, and the usefulness of engaging with communities. We argue that, when facing trade-offs in probable outcomes from communication, it is always best to choose strategies that maintain or build trust, even at the cost of initial overreactions. We discuss these features of successful risk communication in relation to a range of specific examples, particularly opposition to community water fluoridation, Ebola, and routine childhood immunisation.

    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

    Full Text Available Objective To comprehend the development status quo of the management specialty of high-risk medications, to elucidate the trend on relational research field, and to provide a theoretical basis for rational clinical medication. Methods The literature published domestically and abroad was reviewed, the development status on the management specialty of highrisk medications was reviewed, an idea of future development on the research field of high-risk medications was formed, and responsibility of clinicians on high-risk medication management was elucidated. Results The research work of high-risk medication management is still in its infancy in China. Its studies were dispersed in certain areas, with remarkable repetition, and large gaps were found in the research field as compared with that in developed countries. Development of the said discipline and its related research should be strengthened at the present and henceforth. The corresponding society should play a leading role in the development of the discipline. Systemic analysis and comprehensive evaluation should be implemented by applying pharmaceutical epidemiology and evidence-based pharmacology methodology. The catalogue of high-risk medications and the evidencebased guideline of injury prevention against high-risk medications should be established, and the control regulation of high-risk medications should be formulated. The research achievements should be assessed and improved, and then disseminated and applied. An integrated and scientific theoretical system of high-risk medications management should be established, which should contain institutional framework, education, research, and management regulation. Conclusions A joint participation of several disciplines and professions is needed in the research work of high-risk medications management in order to guide the safe and rational use of the drugs. The responsibilities of different professionals, including physicians

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

    Science.gov (United States)

    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.

    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.

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

    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.

    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.

    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.

    Although suicide risk is often thought of as existing on a graded continuum, its latent structure (i.e., whether it is categorical or dimensional) has not been empirically determined. Knowledge about the latent structure of suicide risk holds implications for suicide risk assessments, targeted suicide interventions, and suicide research. Our objectives were to determine whether suicide risk can best be understood as a categorical (i.e., taxonic) or dimensional entity, and to validate the nature of any obtained taxon. We conducted taxometric analyses of cross-sectional, baseline data from 16 independent studies funded by the Military Suicide Research Consortium. Participants (N = 1,773) primarily consisted of military personnel, and most had a history of suicidal behavior. The Comparison Curve Fit Index values for MAMBAC (.85), MAXEIG (.77), and L-Mode (.62) all strongly supported categorical (i.e., taxonic) structure for suicide risk. Follow-up analyses comparing the taxon and complement groups revealed substantially larger effect sizes for the variables most conceptually similar to suicide risk compared with variables indicating general distress. Pending replication and establishment of the predictive validity of the taxon, our results suggest the need for a fundamental shift in suicide risk assessment, treatment, and research. Specifically, suicide risk assessments could be shortened without sacrificing validity, the most potent suicide interventions could be allocated to individuals in the high-risk group, and research should generally be conducted on individuals in the high-risk group.

    Pancreatic cancer is difficult to diagnose at an early stage and is associated with a very poor survival. Ten percent of pancreatic cancers result from genetic susceptibility and/or familial aggregation. Individuals from families with multiple affected first-degree relatives and those with a known cancer-causing genetic mutation have been shown to be at much higher risk of developing pancreatic cancer. Recent efforts have focused on detecting disease at an earlier stage to improve survival in these high-risk groups. This article reviews high-risk groups, screening methods, and current screening programs and their results.
