    Even though Greece has a disproportionate number of haemodialysis stations for the treatment of end-stage renal disease (ESRD), and a rapidly rising number of patients on dialysis, there has been no study of the lived experience of haemodialysis treatment in Greece. ESRD and dialysis drastically impact patients' everyday life, therefore expectations and desires play a major role in adapting to alterations and restrictions. An understanding of these culturally-influenced expectations and desires is essential for the delivery of holistic nursing care. This study aimed to explore how Greek patients receiving long-term haemodialysis perceived their problems and to describe the impact of haemodialysis on their lives. Using a grounded theory approach, 23 patients with ESRD receiving haemodialysis were purposively recruited from two hospital dialysis centres in Athens, Greece. Data were collected during 2006 by personal interviews. Given a distinctive patient experience of haemodialysis, some insight into their common concerns can facilitate provision of healthcare services that adequately meets their needs. By developing an understanding of the experience of renal illness and therapy for a group of people using dialysis, this study was intended as a contribution towards enabling healthcare professionals to provide more effective support to people who are living with this chronic condition.

    Physicians often deal with emotions arising from both patients and themselves; however, management of intense emotions when they arise in the presence of patients is overlooked in research. The aim of this study is to inspect physicians' intense emotions in this context, how these emotions are displayed, coping strategies used, adjustment behaviors, and the impact of the emotional reactions on the physician-patient relationship. A total of 127 physicians completed a self-report survey, built from a literature review. Participants were recruited in 3 different ways: through a snowball sampling procedure, via institutional e-mails, and in person during service meetings. Fifty-two physicians (43.0%) reported experiencing intense emotions frequently. Although most physicians (88.6%) tried to control their reactions, several reported not controlling themselves. Coping strategies to deal with the emotion at the moment included behavioral and cognitive approaches. Only the type of reaction (but not the emotion's valence, duration, relative control, or coping strategies used) seemed to affect the physician-patient relationship. Choking-up/crying, touching, smiling, and providing support were significantly associated with an immediate positive impact. Withdrawing from the situation, imposing, and defending oneself were associated with a negative impact. Some reactions also had an extended impact into future interactions. Experiencing intense emotions in the presence of patients was frequent among physicians, and the type of reaction affected the clinical relationship. Because many physicians reported experiencing long-lasting emotions, these may have important clinical implications for patients visiting physicians while these emotions last. Further studies are needed to clarify these results.

    Objectives Environmental sound perception serves an important ecological function by providing listeners with information about objects and events in their immediate environment. Environmental sounds such as car horns, baby cries or chirping birds can alert listeners to imminent dangers as well as contribute to one's sense of awareness and well being. Perception of environmental sounds as acoustically and semantically complex stimuli, may also involve some factors common to the processing of speech. However, very limited research has investigated the abilities of cochlear implant (CI) patients to identify common environmental sounds, despite patients' general enthusiasm about them. This project (1) investigated the ability of patients with modern-day CIs to perceive environmental sounds, (2) explored associations among speech, environmental sounds and basic auditory abilities, and (3) examined acoustic factors that might be involved in environmental sound perception. Design Seventeen experienced postlingually-deafened CI patients participated in the study. Environmental sound perception was assessed with a large-item test composed of 40 sound sources, each represented by four different tokens. The relationship between speech and environmental sound perception, and the role of working memory and some basic auditory abilities were examined based on patient performance on a battery of speech tests (HINT, CNC, and individual consonant and vowel tests), tests of basic auditory abilities (audiometric thresholds, gap detection, temporal pattern and temporal order for tones tests) and a backward digit recall test. Results The results indicated substantially reduced ability to identify common environmental sounds in CI patients (45.3%). Except for vowels, all speech test scores significantly correlated with the environmental sound test scores: r = 0.73 for HINT in quiet, r = 0.69 for HINT in noise, r = 0.70 for CNC, r = 0.64 for consonants and r = 0.48 for vowels.

    The primary aim of the present study was to consider health care service quality from the patients' perspective, specifically through the patient's eyes. A narrative analysis was performed on 300 patient stories. This rigorous analysis of patient stories is designed to identify and describe health care service quality through patients' eyes in an authentic and accurate, experiential manner. The findings show that there are variant and complex ways that patients experience health care service quality. Patient stories offer an authentic view of the complex ways that patients experience health care service quality. Narrative analysis is a useful tool to identify and describe how patients experience health care service quality. Patients experience health care service quality in complex and varying ways.

Inpatient and outpatient management and treatment of fractures can be costly. With more emphasis placed on quality care for Medicare beneficiaries, we studied if patients were receiving proper screening for osteoporosis and treatment after diagnosis of fracture. This study aims to determine if adequate screening and treatment for osteoporosis occurs in the postfracture period.Methods: A retrospective analysis of Medicare beneficiaries aged 67 years or older was gathered from a single institution in both inpatient and outpatient visits. Based on International Classification of Diseases ninth revision codes, primary diagnosis of fractures of neck and trunk, upper limb, and lower limb were obtained in addition to current procedural terminology codes for fracture procedures. We studied patients who had been screened for osteoporosis with a bone mineral study or received osteoporosis treatment after their fracture.Results: Medicare beneficiaries totaling 1,375 patients were determined to have an inclusion fracture between June 1, 2013 and November 30, 2014. At the time of our analysis on December 1, 2014, 1,219 patients were living and included in the analysis. Of these patients, 256 (21.0% either received osteoporosis testing with bone mineral density or received treatment for osteoporosis. On sex breakdown, 208/820 (25.4% females received proper evaluation or treatment of osteoporosis in comparison to 48/399 (12.0% males.

    Full Text Available Objective: Haemodialysis and peritoneal dialysis renal replacement treatment options are in clinical equipoise, although the cost of haemodialysis to the National Health Service is £16,411/patient/year greater than peritoneal dialysis. Treatment decision-making takes place during the pre-dialysis year when estimated glomerular filtration rate drops to between 15 and 30 mL/min/1.73 m2. Renal disease can be familial, and the majority of patients have considerable health service experience when they approach these treatment decisions. Factors affecting patient treatment decisions are currently unknown. The objective of this article is to explore data from a wider study in specific relation to the types of vicarious learning experiences reported by pre-dialysis patients. Methods: A qualitative study utilised unstructured interviews and grounded theory analysis during the participant’s pre-dialysis year. The interview cohort comprised 20 pre-dialysis participants between 24 and 80 years of age. Grounded theory design entailed thematic sampling and analysis, scrutinised by secondary coding and checked with participants. Participants were recruited from routine renal clinics at two local hospitals when their estimated glomerular filtration rate was between 15 and 30 mL/min/1.73 m2. Results: Vicarious learning that contributed to treatment decision-making fell into three main categories: planned vicarious leaning, unplanned vicarious learning and historical vicarious experiences. Conclusion: Exploration and acknowledgement of service users’ prior vicarious learning, by healthcare professionals, is important in understanding its potential influences on individuals’ treatment decision-making. This will enable healthcare professionals to challenge heuristic decisions based on limited information and to encourage analytic thought processes.

Methods: Medical and pharmacy claims from a US commercially-insured population were analyzed to select adult patients newly diagnosed with a fracture nonunion between July 2006 and September 2009. The date of initial nonunion diagnosis was set as the index date. Three cohorts were constructed based on the first treatment prescribed post index date: EBGS, LIPUS, or No-stim. Baseline demographics, clinical characteristics, and health care costs 9 months before and 1 year after the index date were assessed. Multivariate regression analyses were performed to compare health care costs between cohorts in the post index period. Results: 11,628 patients (mean age 45.4 years; 45.7% males with a fracture nonunion were identified within the three treatment groups (EBGS: 29.5%, LIPUS: 12.3%, and No-stim: 58.2%.

    We examined patients' experiences of patient safety and participation in promoting safe care during their most recent care period. A survey of patients (N = 175) revealed that treatment, medication, and device safety were mostly experienced as very good or excellent, but responses varied by age and experience. Patients ages 66-75 were most critical of treatment and medication safety. Device safety was rated the worst aspect of safety. Twenty percent of respondents had experienced errors at some time during their care. Patients who had experienced errors and those who were treated at inpatient wards versus a day surgery unit were most critical towards patient participation. Open and transparent error management involving patients is needed to promote treatment, medication, and especially device safety. © 2014 Wiley Periodicals, Inc.

    The aim of this research was to examine the relationship between therapist interventions and patient affect responses in Short-Term Dynamic Psychotherapy (STDP). The Affect Experiencing subscale from the Achievement of Therapeutic Objectives Scale (ATOS) was adapted to measure individual immediate affect experiencing (I-AES) responses in relation to therapist interventions coded within the preceding speaking turn, using the Psychotherapy Interaction Coding (PIC) system. A hierarchical linear modelling procedure was used to assess the change in affect experiencing and the relationship between affect experiencing and therapist interventions within and across segments of therapy. Process data was taken from six STDP cases; in total 24 hours of video-taped sessions were examined. Therapist interventions were found to account for a statistically significant amount of variance in immediate affect experiencing. Higher levels of immediate affect experiencing followed the therapist's use of Confrontation, Clarification and Support compared to Questions, Self-disclosure and Information interventions. Therapist Confrontation interventions that attempted to direct pressure towards either the visceral experience of affect or a patient's defences against feelings led to the highest levels of immediate affect experiencing. The type of therapist intervention accounts for a small but significant amount of the variation observed in a patient's immediate emotional arousal. Empirical findings support clinical theory in STDP that suggests strategic verbal responses promote the achievement of this specific therapeutic objective.

    The aim of this study was to investigate the impact of caregiver knowledge and experience on muscle activity and perceived exertion while repositioning bedridden patients. Subjects were 40- to 65-year-old female caregivers divided into novice and experienced groups. Subjects from both groups performed home-care repositioning techniques on bedridden patients while muscle activity was recorded via electromyogram. Recordings were made from four muscles on the subjects' dominant side: the latissimus dorsi, the biceps brachii, the erector spinae, and the rectus femoris. The subjective burden involved in repositioning was also assessed using the rate of perceived exertion (RPE) and visual analog scales (VAS). Rectus femoris percentage of maximum voluntary contraction (%MVC) values were significantly lower than latissimus dorsi, erector spinae, and biceps brachii values in the novice group. %MVC values from the latissimus dorsi and biceps brachii were significantly higher among the novice group compared to the experienced group. RPE ratings from the novice group were significantly higher than those of the experienced group, and there was a non-significant trend for higher VAS values for the low back, arms, and legs in the novice group compared to the experienced group. Novice caregivers tended to change the patient's position by pulling with the upper limbs without using the lower limbs. In contrast, experienced caregivers exerted less energy by communicating with the patient and utilizing the patient's own movements. They used large, distributed muscle groups that effectively harnessed body mechanics and prevented excess exertion.

    This study aimed to evaluate the stigma and its correlates among patients with severe mental disorders. Patients with diagnosis of schizophrenia (N = 707), bipolar disorder (N = 344) and recurrent depressive disorder (N = 352) currently in clinical remission from 14 participating centres were assessed on Internalized Stigma of Mental Illness Scale (ISMIS). Patients with diagnosis of schizophrenia experienced higher level of alienation, sterotype endorsement, discrimination experience and total stigma when compared to patients with bipolar disorder and recurrent depressive disorder. Patients with bipolar disorder experienced higher stigma than those with recurrent depressive disorder in the domain of stigma resistance only. Overall compared to affective disorder groups, higher proportion of patients with schizophrenia reported stigma in all the domains of ISMIS. In general in all the 3 diagnostic groups' stigma was associated with shorter duration of illness, shorter duration of treatment and younger age of onset. To conclude, this study suggests that compared to affective disorder, patients with schizophrenia experience higher self stigma. Higher level of stigma is experienced during the early phase of illness. Stigma intervention programs must focus on patients during the initial phase of illness in order to reduce the negative consequences of stigma. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study examined whether the occurrence and timing of parental separation or divorce was related to trajectories of academic grades and mother- and teacher-reported internalizing and externalizing problems. The authors used hierarchical linear models to estimate trajectories for children who did and did not experience their parents' divorce or separation in kindergarten through 10th grade (N = 194). A novel approach to analyzing the timing of divorce/separation was adopted, and trajectories were estimated from 1 year prior to the divorce/separation to 3 years after the event. Results suggest that early parental divorce/separation is more negatively related to trajectories of internalizing and externalizing problems than is later divorce/separation, whereas later divorce/separation is more negatively related to grades. One implication of these findings is that children may benefit most from interventions focused on preventing internalizing and externalizing problems, whereas adolescents may benefit most from interventions focused on promoting academic achievement.

    Treatment options are limited for HIV-1-infected individuals who have received extensive previous antiretroviral therapy. ETV has shown significant clinical benefits in treatment-experienced HIV-1+ patients with antiretroviral resistance. The aim of this study was to evaluate the effectiveness of ETV plus optimized background regimen in real-life conditions in a cohort of highly HIV-1 antiretroviral-experienced patients. Retrospective cohort of treatment-experienced HIV-1-infected adults with virological failure who started therapy with an ETV-containing regimen. The effectiveness was evaluated using HIV-1 RNA viral load and changes in CD4+ cell count after 48 weeks of treatment. Forty-two patients ≥ 16 years of age were included; 74% were men, and the median age was 45 years (IQR 41-53). All participants had prior non-nucleoside reverse transcriptase inhibitor use (55% nevirapine, 83%, efavirenz, and 28% both). Baseline median HIV-1 RNA viral load was 15,598 copies/mL (IQR 2651-84,175) and CD4+ cell count was 276 cells/mL (IQR 155-436). After 48 weeks of treatment, 90.5% (95% CI 78-96) of patients had HIV-1 RNA viral load treatment to a median of 407 cells/mL (IQR 242-579); p HIV-1 RNA viral load ≥ 100,000 copies/mL (OR 7.6; 95% CI 1.2-44.80; p = 0.025). Our study provides clinically important evidence of the effectiveness and safety of ETV in highly antiretroviral-experienced HIV-1-infected patients.

Most HIV clinics apply the patient self-report (PSR method. However, the reliability of this method in experienced HIV patients remains questionable.Purpose: To validate the PSR method for measuring adherence to ART using lamivudine (3TC plasma concentrations in experienced HIV patients.Methods: The study was conducted in Dar Es Salaam and involved 220 patients who were receiving ART services at HIV clinics for more than 12 months. Self-reported adherence information to ART was obtained on the day of HIV clinic visit. The patients were asked to mention the number of doses missed within the past 7 days. In addition, blood samples (2 mL were collected from each patient on the same day. The blood samples were determined for 3TC plasma concentrations. The target 3TC plasma concentration as indicator concentration for adherent patients was determined in 20 patients who took their evening dose of antiretrovirals under supervision. The blood from these patients was drawn 3 hours after drug administration.Results: Complete drug levels of 3TC and self-reported adherence data was obtained in 200 treatment-experienced HIV patients. Lamivudine plasma concentrations obtained in these patients ranged between 0.02–17.36 µg/mL. The mean time from dose administration to blood drawing was 3.1 ± 1.2 hours with coefficient of variation >39%.

    Full Text Available OBJECTIVE: The relationship between brain tumors and cognitive deficits is well established in the literature. However, studies investigating the cognitive status in low and high-grade gliomas patients are scarce, particularly in patients with average or lower educational level. This study aimed at investigating the cognitive functioning in a sample of patients with low and high-grade gliomas before surgical intervention. METHOD: The low-grade (G1, n=19 and high-grade glioma (G2, n=8 patients underwent a detailed neuropsychological assessment of memory, executive functions, visuo-perceptive and visuo-spatial abilities, intellectual level and language. RESULTS: There was a significant impairment on verbal and visual episodic memory, executive functions including mental flexibility, nominal and categorical verbal fluency and speed of information processing in G2. G1 showed only specific deficits on verbal and visual memory recall, mental flexibility and processing speed. CONCLUSION: These findings demonstrated different levels of impairments in the executive and memory domains in patients with low and high grade gliomas.

    This study aims to examine Gender Difference in the level of Discrimination and Stigma experienced by people diagnosed with Major Depressive Disorder in Pakistan. It was hypothesized that Women diagnosed with Depression are likely to be experiencing more Discrimination and Internalized Stigma in comparison to Men. This is a Cross Sectional Study. Thirty eight patients diagnosed with Major Depressive Disorder recruited from different Government Sector Hospitals of Lahore; were approached after obtaining informed consent. Discrimination and Stigma were measured through Discrimination and Stigma Scale and Internalized Stigma of Mental Illness Inventory respectively. Both Men and Women experience considerably high level of associated Stigma and Discrimination due to their Mental Illness. However, Women in comparison to Men experience significantly greater level of Internalized Stigma especially in domains of Discrimination Experience and Social Withdrawal. The findings of this study highlight the fact that people with Depression can be more benefited with psychological treatment if dealing with Stigma and Discrimination is also addressed in Intervention Plans.

    Although both tipranavir (TPV) and darunavir (DRV) represent important options for the management of patients with multi-protease inhibitor (PI)-resistant human immunodeficiency virus (HIV), currently there are no studies comparing the effectiveness and safety of these two drugs in the Mexican population. The aim of this study was to compare the effectiveness of TPV versus DRV as a salvage therapy in HIV-1 treatment-experienced patients. This was a comparative, prospective, cohort study. Patients with HIV and triple-class drug resistance evaluated at the Hospital de Infectología "La Raza", National Medical Center, were included. All patients had the protease and retrotranscriptase genotype; resistance mutation interpretation was done using the Stanford database. A total of 35 HIV-1 triple-class drug-resistant patients were analyzed. All of them received tenofovir and raltegravir, 22 received darunavir/ritonavir (DRV/r), and 13 received tipranavir/ritonavir (TPV/r) therapies. The median baseline RNA HIV-1 viral load and CD4+ cell count were 4.34 log (interquartile range [IQR], 4.15-4.72) and 267 cells/mm3 (IQR, 177-320) for the DRV/r group, and 4.14 log (IQR, 3.51-4.85) and 445 cells/mm3 (IQR, 252-558) for the TPV/r group. At week 24 of treatment, 91% of patients receiving DRV/r and 100% of patients receiving TPV/r had an RNA HIV-1 viral load HIV-1 patients who were highly experienced in antiretroviral therapy.

    Seizures frequently impact the quality of life of patients with low grade tumors. Management is often based on best clinical judgment. We examined factors that correlate with seizure outcome to optimize seizure management. Patients with supratentorial low-grade tumors evaluated at a single institution were retrospectively reviewed. Using multiple regression analysis the patient characteristics and treatments were correlated with seizure outcome using Engel's classification. Of the 73 patients with low grade tumors and median follow up of 3.8 years (range 1-20 years), 54 (74%) patients had a seizure ever and 46 (63%) had at least one seizure before tumor surgery. The only factor significantly associated with pre-surgical seizures was tumor histology. Of the 54 patients with seizures ever, 25 (46.3%) had a class I outcome at last follow up. There was no difference in seizure outcome between grade II gliomas (astrocytoma grade II, oligodendroglioma grade II, mixed oligo-astrocytoma grade II) and other pathologies (pilocytic astrocytoma, ependymomas, DNET, gangliocytoma and ganglioglioma). Once seizures were established seizure prognosis was similar between different pathologies. Chemotherapy (p=0.03) and radiation therapy (p=0.02) had a positive effect on seizure outcome. No other parameter including significant tumor growth during the follow up period predicted seizure outcome. Only three patients developed new-onset seizures after tumor surgery that were non-perioperative. Anticonvulsant medication was tapered in 14 patients with seizures and 10 had no further seizures. Five patients underwent additional epilepsy surgery with a class I outcome in four. Two patients received a vagal nerve stimulator with >50% seizure reduction. Seizures at presentation are the most important factor associated with continued seizures after tumor surgery. Pathology does not influence seizure outcome. Use of long term prophylactic anticonvulsants is unwarranted. Chemotherapy and

    The inclusion of simulated patients (SPs) in health professional education is growing internationally. However, there is limited evidence for best practice in SP methodology. This study investigated how experienced SP educators support SPs in providing SP-based education for health professional students. Experienced SP educators were identified via relevant professional associations, peer-reviewed publications, and peer referral. Semi-structured individual interviews were conducted via telephone. Data were analyzed independently by three researchers using principles of inductive thematic analysis. Four themes were identified that represent the key structural components of SP programs considered by educators seeking to optimize learning for health professional students in SP programs: managing SPs by operationalizing an effective program, selecting SPs by rigorously screening for suitability, preparing SPs by educating for a specific scenario, and directing SPs by leading safe and meaningful interactions. Within these components, subthemes were described, with considerable variation in approaches. Key structural components to SP programs were consistently described by experienced SP educators who operationalize them. A framework has been proposed to assist educators in designing high-quality SP programs that support SPs and learners. Future research is required to evaluate and refine this framework and other evidence-based resources for SP educators.

    Evidence shows that music therapy aids in symptom management and improves quality of life for palliative medicine and hospice patients. The majority of previous studies have addressed patient needs, while only a few addressed the needs of family members. The primary purpose of this study was to understand family members' perceptions of music therapy experienced by a relative in palliative medicine or hospice. Patient self-reported scales and music therapist assessment of change were also investigated. Patients scored their symptoms (pain, anxiety, depression, shortness of breath, and mood) before and after music therapy sessions. One family member present during the session assessed perceived effect on the patient's pain, anxiety, depression, shortness of breath, stress level, restlessness, comfort level, mood, and quality of life. The effect on family member's stress level, quality of life, and mood and helpfulness of the music therapy session for the patient and self were studied. Recommendations about future patient participation in music therapy and qualitative comments were also solicited. Fifty family member/patient dyads participated in the study. Family member perceptions were positive, with 82% of responders indicating improvement for self and patient in stress, mood, and quality of life; 80% rating the session as extremely helpful; and 100% of 49 recommending further music therapy sessions for the patient. Patients reported statistically significant improvement in pain, depression, distress, and mood scores. Family members of patients in palliative medicine and hospice settings reported an immediate positive impact of music therapy on the patient and on themselves. More research needs to be conducted to better understand the benefits of music therapy for family members.

    Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous condition characterized by occasional exacerbations. Identifying clinical subtypes among patients experiencing COPD exacerbations (ECOPD) could help better understand the pathophysiologic mechanisms involved in exacerbations, establish different strategies of treatment, and improve the process of care and patient prognosis. The objective of this study was to identify subtypes of ECOPD patients attending emergency departments using clinical variables and to validate the results using several outcomes. We evaluated data collected as part of the IRYSS-COPD prospective cohort study conducted in 16 hospitals in Spain. Variables collected from ECOPD patients attending one of the emergency departments included arterial blood gases, presence of comorbidities, previous COPD treatment, baseline severity of COPD, and previous hospitalizations for ECOPD. Patient subtypes were identified by combining results from multiple correspondence analysis and cluster analysis. Results were validated using key outcomes of ECOPD evolution. Four ECOPD subtypes were identified based on the severity of the current exacerbation and general health status (largely a function of comorbidities): subtype A (n = 934), neither high comorbidity nor severe exacerbation; subtype B (n = 682), moderate comorbidities; subtype C (n = 562), severe comorbidities related to mortality; and subtype D (n = 309), very severe process of exacerbation, significantly related to mortality and admission to an intensive care unit. Subtype D experienced the highest rate of mortality, admission to an intensive care unit and need for noninvasive mechanical ventilation, followed by subtype C. Subtypes A and B were primarily related to other serious complications. Hospitalization rate was more than 50% for all the subtypes, although significantly higher for subtypes C and D than for subtypes A and B. These results could help identify

    Delirium is a common occurrence for patients in the intensive care unit and can have a profound and lasting impact on them. Few studies describe the experience of intensive care patients who have had delirium. To understand the lived experience of intensive care for critically ill patients who experienced delirium. The study participants consisted of 7 men and 3 women, 46 to 70 years old, who had delirium according to the Confusion Assessment Method for the Intensive Care Unit. The van Manen method of hermeneutic phenomenology was used, and data collection entailed audio recorded semistructured interviews. Four themes were detected: "I can't remember," "Wanting to make a connection," "Trying to get it straight," and "Fear and safety concerns." Nurses working in intensive care units need to assess patients for delirium, assess the mental status of patients who have delirium, and help patients and patients' families learn about and deal with the psychological effects of the intensive care unit experience. ©2015 American Association of Critical-Care Nurses.

    To establish the prevalence of new vestibular and otological symptoms in a group of patients who had sustained a low grade (Quebec grades one or two) whiplash injury. A retrospective review of the case records of 109 patients undergoing assessment by a single practitioner for the purposes of compiling a medicolegal report on their whiplash injury. Four patients complained of short-lived, non-specific dizziness symptoms in the acute phase following their original injury. There were no reports of vertigo, tinnitus or hearing loss after a mean period of 149 days following the whiplash injury. No patients reported otological or persistent vestibular symptoms in the acute phase following their whiplash injury. This suggests that caution should be exercised when attributing these symptoms to such an injury. Before whiplash injuries are admitted as an aetiological factor in the development of such symptoms, other causes should be excluded.

    Parkinson's disease (PD) is a neurodegenerative disease characterized by motor and nonmotor symptoms. Both of them imply a negative impact on Health-Related Quality of Life. A significant one is the stigma experienced by the parkinsonian patients and their caregivers. Moreover, stigma may affect everyday life and patient's subjective and relational perception and it may lead to frustration and isolation. Aim of the present work is to qualitatively describe the stigma of PD patients stemming from literature review, in order to catch the subjective experience and the meaning of the stigma construct. Literature review was performed on PubMed database and Google Scholar (keywords: Parkinson Disease, qualitative, stigma, social problem, isolation, discrimination) and was restricted to qualitative data: 14 articles were identified to be suitable to the aim of the present overview. Results are divided into four core constructs: stigma arising from symptoms, stigma linked to relational and communication problems, social stigma arising from sharing perceptions, and caregiver's stigma. The principal relations to these constructs are deeply analyzed and described subjectively through patients' and caregiver's point of view. The qualitative research may allow a better understanding of a subjective symptom such as stigma in parkinsonian patients from an intercultural and a social point of view.

    The Tidal Model has been implemented in Rangipapa, a regional secure mental health forensic unit in New Zealand. A phenomenological study was undertaken to obtain reflective description of the nursing care experience from the perspective's of four Registered Nurses and four Special Patients. Five major themes were identified that appeared to capture the experiences of the participants. The themes show changes to the unit's unique culture and values following implementation of the model. These changes engendered a sense of hope, where nurses felt they were making a difference and patients were able to communicate in their own words their feelings of hope and optimism. Levelling was experienced as an effect emerging from individual and group processes whereby a shift in power enhanced a sense of self and connectedness in their relationships. These interpersonal transactions were noted by the special patients as being positive for their recovery. This enabled effective nurse-patient collaboration expressed simply as working together. The participants reported a feeling of humanity, so that there was a human face to a potentially objectifying forensic setting. Implications arising from this study are that the use of the model enables a synergistic interpersonal process wherein nurses are professionally satisfied and patients are validated in their experience supporting their recovery.

    To examine the safety and tolerability of clinical graded aerobic treadmill testing in recovering adolescent moderate and severe traumatic brain injury (TBI) patients referred to a multidisciplinary pediatric concussion program. We completed a retrospective case series of two moderate and five severe TBI patients (mean age, 17.3 years) who underwent initial Buffalo Concussion Treadmill Testing at a mean time of 71.6 days (range, 55-87) postinjury. Six patients completed one graded aerobic treadmill test each and one patient underwent initial and repeat testing. There were no complications. Five initial treadmill tests were completely tolerated and allowed an accurate assessment of exercise tolerance. Two initial tests were terminated early by the treatment team because of neurological and cardiorespiratory limitations. As a result of testing, two patients were cleared for aerobic exercise as tolerated and four patients were treated with individually tailored submaximal aerobic exercise programs resulting in subjective improvement in residual symptoms and/or exercise tolerance. Repeat treadmill testing in one patient performed after 1 month of treatment with submaximal aerobic exercise prescription was suggestive of improved exercise tolerance. One patient was able to tolerate aerobic exercise following surgery for posterior glottic stenosis. Preliminary results suggest that graded aerobic treadmill testing is a safe, well tolerated, and clinically useful tool to assess exercise tolerance in appropriately selected adolescent patients with TBI. Future prospective studies are needed to evaluate the effect of tailored submaximal aerobic exercise prescription on exercise tolerance and patient outcomes in recovering adolescent moderate and severe TBI patients.

    Full Text Available Aim: The aim of this study was to evaluate the effectiveness of a nursing intervention protocol targeting the knowledge and practice of adult patients experiencing low back pain. Design: A quasi-experimental research design. Methods: Pre-post assessment of outcome was used in this study. The study was conducted in the outpatient clinic of the physical therapy department at Zagazig University Hospital and Beni-Suef University Hospital, Egypt. Sample: 40 participants diagnosed with chronic low back pain (lasting for longer than six months. Seven of the 40 dropped out during the follow-up phase for personal or logistical reasons. Tools included sections for demographic characteristics, knowledge and practice assessment; in addition to the Oswestry Disability Index, and Visual Analogue Scale (VAS. Results: The application of an instruction protocol intervention for low back pain was effective in improving patient knowledge and practice, with associated amelioration of the severity of pain and disability among them. The effect was still apparent at the three-month follow-up. Conclusion: It is recommended that the study be replicated using a more robust randomized clinical trial design. Nonetheless, the instruction protocol with the designed booklet may be adopted as an element of the care services offered to patients suffering LBP, given the clear positive effects on patient knowledge, which would undoubtedly help them decide on the most preferential management approach.

    Death and dying are inevitable life encounters, but a nurse's first experience with patient death may pose considerable cognitive, emotional and clinical challenges. This paper reports the findings of the second phase of a study; the first has been reported elsewhere. This phase explored the earliest memorable patient death experiences of New Zealand registered nurses. A purposeful, self-selected sub-sample of a larger study of New Zealand registered nurses, took part in individual face-to-face semi-structured interviews. Interpretative phenomenological analysis was utilised to seek to understand participants' experiences. Thematic analysis was undertaken to identify emerging themes, with participants' own words used as theme headings, where their phrases provided succinct or powerful descriptors. A diverse participant group of twenty, currently practising, New Zealand registered nurses provided rich and detailed descriptions of their earliest memorable experience with patient death. Participants from a variety of training backgrounds described patient deaths, which occurred in a range of settings - some only a few months prior, others - more than thirty years ago. Seven emergent themes, and features of more positive, or negative experiences were identified: Event Significance; Emotional Challenges; Sharing the Experience; Learning; Feeling Unprepared, Responses to Death and Finding Benefits. For participants in this study, there was considerable evidence that their earliest memorable patient death was a significant event. Furthermore, although most participants' experiences were characterised by emphatic or poignant description, there was most often a balance of challenges and rewards. Copyright © 2014 Elsevier Ltd.

    The purpose of this study was to gain an insight into nurses' experiences of incorporating aromatherapy into the care of residents suffering from dementia, anxiety and disturbed sleep patterns. Twenty-four residents and twelve nurses from four nursing homes participated in an action research study. The use of lavender augustofolia essential oil diffused nightly was perceived as an effective care modality reducing insomnia and anxiety in this patient cohort. Nurses experienced some negative attitudes among colleagues because they considered aromatherapy as not evidence based. Nurses require greater access to evidence based use of Aromatherapy. Further research is needed to study how smell can enhance dementia care. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Parkinson’s disease (PD is a neurodegenerative disease characterized by motor and nonmotor symptoms. Both of them imply a negative impact on Health-Related Quality of Life. A significant one is the stigma experienced by the parkinsonian patients and their caregivers. Moreover, stigma may affect everyday life and patient’s subjective and relational perception and it may lead to frustration and isolation. Aim of the present work is to qualitatively describe the stigma of PD patients stemming from literature review, in order to catch the subjective experience and the meaning of the stigma construct. Literature review was performed on PubMed database and Google Scholar (keywords: Parkinson Disease, qualitative, stigma, social problem, isolation, discrimination and was restricted to qualitative data: 14 articles were identified to be suitable to the aim of the present overview. Results are divided into four core constructs: stigma arising from symptoms, stigma linked to relational and communication problems, social stigma arising from sharing perceptions, and caregiver’s stigma. The principal relations to these constructs are deeply analyzed and described subjectively through patients’ and caregiver’s point of view. The qualitative research may allow a better understanding of a subjective symptom such as stigma in parkinsonian patients from an intercultural and a social point of view.

    Dolutegravir is an HIV integrase inhibitor with a high genetic barrier to resistance and is active against raltegravir- and/or elvitegravir-resistant strains. The clinical development of dolutegravir for HIV infection rescue therapy is based on 3 clinical trials. In the SAILING trial, dolutegravir (5 mg once daily) in combination with 2 other antiretroviral agents was well tolerated and showed greater virological effect than raltegravir (400 mg twice daily) in the treatment of integrase inhibitor-naïve adults with virological failure infected with HIV strains with at least two-class drug resistance. The VIKING studies were designed to evaluate the efficacy of dolutegravir as rescue therapy in treatment-experienced patients infected with HIV strains with resistance mutations to raltegravir and/or elvitegravir. VIKING-1-2 was a dose-ranging phase IIb trial. VIKING-3 was a phase III trial in which dolutegravir (50 mg twice daily) formed part of an optimized regimen and proved safe and effective in this difficult-to-treat group of patients. Dolutegravir is the integrase inhibitor of choice for rescue therapy in multiresistant HIV infection, both in integrase inhibitor-naïve patients and in those previously treated with raltegravir or elvitegravir.

    Full Text Available Currently circulatory diseases are the first cause of death in Brazil and worldwide. After the diagnosis of Acute Myocardial Infarction the patient is faced with a new and daunting routine, a fact that constitutes a source of different and ambiguous feelings. In this context nursing has a fundamental role of providing adequate care to these patients. This study aimed at analyzing the feelings experienced by inpatients in a medical treatment unit when faced with Acute Myocardial Infarction (AMI for the first time. This is an exploratory, descriptive study, with a qualitative approach. Seven inpatients participated in the study at diagnosis of first AMI in a medical treatment unit at a public hospital in the municipality of Sinop. Data were collected through semi-structured interviews. The analysis was carried out through the thematic content analysis technique. The study complied with the ethic principles governing research involving human subjects, under Resolution no. 466/2012. The project was submitted to the Research Ethic Committee and approved by Decision 632.272. The categories listed from the accounts were: a expectation of improvement and adoption of measures to promote health; b negative feelings after AMI. Given the above, we concluded that, although the subjects presented positive and negative feelings towards the event, the impact of AMI on patients’ lives must be considered likewise by the health team, especially by the professional since these feelings are generators of anguish and stress

    The aim of this prospective longitudinal study was to compare pain experiences among Chinese adult patients treated with labial and lingual orthodontic appliances. Sixty patients, 30 with labial appliances (18 females and 12 males, mean age 20.33 years, SD +/- 4.205) and 30 with lingual appliances (22 females and 8 males, mean age 21.63 years, SD +/- 2.236), rated their overall pain experience on a 100 mm visual analogue scale (VAS) at three time points: 1 week (T(1)), 1 month (T(2)), and 3 months (T(3)) after bracket placement. In addition, on a separate 100 mm VAS, they rated their pain experience at the locations of the tongue, lips, cheeks, gums, face, and jaw at T(1), T(2), and T(3). Changes in pain VAS were conducted using Friedman analysis of variance, area under the curve (AUC) analysis and the data were compared using a t-test. There was no significant difference in global ratings of pain among those treated with labial or lingual appliances (P > 0.05). Among both groups, global ratings of pain decreased over the study period (P appliances reported higher ratings of tongue pain (P appliances reported higher ratings of lip (P appliances rate similarly the level of overall pain they experience during treatment. Ratings of overall pain experienced decreased for both treatment groups with time. However, ratings of pain differed at various sites with respect to the type of orthodontic appliance. These findings have implications in informing patients' treatment decision-making processes regarding labial and lingual appliances and in the management of discomfort associated with different treatment modalities.

    Full Text Available Abstract Introduction The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. Methods This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Results Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5% who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%; one patient developed a tracheal stenosis (secondary to tracheal intubation; one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. Conclusions In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

    In patients with newly diagnosed untreated grade I-II hypertension, EEG oscillations were recorded under conditions activation of the two basic motivational systems, defensive motivational system and positive reinforcement system, evoked by recall of personally meaningful emotional events. The 64-channel EEG and cardiovascular reactivity (beat-by-beat technology) were simultaneously recorded. At rest, hypertensive patients had significantly reduced platelet serotonin concentrations in comparison with healthy individuals. The patients experiencing emotional activation were characterized by significantly lower intensity of positive emotions associated with more pronounced suppression of EEG activity in the delta (2-4 Hz) and theta (ranges of frequency 4-6 and 6-8 Hz) oscillators in the parieto-occipital cortex (zones P and PO) in both hemispheres of the brain. The findings attest to insufficient function of the brain serotonin system and hypoactivation of the reward/reinforcement system in patients with primary hypertension.

    Full Text Available Stroke affects individuals in a number of ways. The InternationalClassification of Functioning, Disability and Health can be used to conceptualizedisability post stroke. This framework not only identifies the factors as it relatesto disability but also highlights the conceptual factors which impacts on theindividual’s ability to function. Within the framework of the ICF, the aim of thestudy was therefore to explore the activity limitations and participation restrictionsexperienced by patients with a stroke. A qualitative approach was used to interviewa convenient sample of 8 participants who were living in the community. A semistructuredinterview was conducted to obtain the data. The findings reveal that the participants had impairments of bodyfunctions of both the upper and lower limb. They experienced limitations in activities such as caring for themselves andmobility and were restricted in their ability to fulfill roles such work and caring for family. The factors which influencedthe above were personal factors such as impairments and environmental factors such as family and therapy. This studyprovides valuable qualitative information that could be used by health care professionals when providing rehabilitationservices to people with stroke aimed at reintegration back into the community.

    Full Text Available Abstract Background HIV integrase inhibitor use is limited by low genetic barrier to resistance and possible cross-resistance among representatives of this class of antiretrovirals. The aim of this study was to analyse integrase sequence variability among antiretroviral treatment naive and experienced patients with no prior integrase inhibitor (InI exposure and investigate development of the InI drug resistance mutations following the virologic failure of the raltegravir containing regimen. Methods Sequencing of HIV-1 integrase region from plasma samples of 80 integrase treatment naive patients and serial samples from 12 patients with observed virologic failure on raltegravir containing treatment whenever plasma vireamia exceeded >50 copies/ml was performed. Drug resistance mutations were called with Stanford DB database and grouped into major and minor variants. For subtyping bootstrapped phylogenetic analysis was used; Bayesian Monte Carlo Marcov Chain (MCMC model was implemented to infer on the phylogenetic relationships between the serial sequences from patients failing on raltegravir. Results Majority of the integrase region sequences were classified as subtype B; the remaining ones being subtype D, C, G, as well as CRF01_AE , CRF02_AG and CRF13_cpx recombinants. No major integrase drug resistance mutations have been observed in InI-treatment naive patients. In 30 (38.5% cases polymorphic variation with predominance of the E157Q mutation was observed. This mutation was more common among subtype B (26 cases, 54.2% than non-B sequences (5 cases, 16.7%, p=0.00099, OR: 5.91 (95% CI:1.77-22.63]. Other variants included L68V, L74IL, T97A, E138D, V151I, R263K. Among 12 (26.1% raltegravir treated patients treatment failure was observed; major InI drug resistance mutations (G140S, Q148H and N155H, V151I, E92EQ, V151I, G163R were noted in four of these cases (8.3% of the total InI-treated patients.

    In the end-of-life (EOL) phase, high-grade glioma (HGG) patients have a high symptom burden and often lose independence because of physical and cognitive dysfunction. This might affect the patient's personal dignity. We aimed to (a) assess the proportion of HGG patients dying with dignity as perceived by their relatives and (b) identify disease and care factors correlated with dying with dignity in HGG patients. We approached relatives of a cohort of 155 deceased HGG patients for the study. Participants completed a questionnaire concerning the EOL phase of the patient, covering several subthemes: (a) symptoms and signs, (b) health-related quality of life, (c) decision making, (d) place and quality of EOL care, and (e) dying with dignity. Relatives of 81 patients participated and 75% indicated that the patient died with dignity. These patients had fewer communication deficits, experienced fewer transitions between health care settings in the EOL phase, and more frequently died at their preferred place of death. Relatives were more satisfied with the physician providing EOL care and reported that the physician adequately explained treatment options. Multivariate analysis identified satisfaction with the physician, the ability to communicate, and the absence of transitions between settings as most predictive of a dignified death. Physicians caring for HGG patients in the EOL phase should timely focus on explaining possible treatment options, because patients experience communication deficits toward death. Physicians should strive to allow patients to die at their preferred place and avoid transitions during the last month of life.

    Evidence about the use of dolutegravir (DTG) and rilpivirine (RPV) as an antiretroviral therapy (ART) in treatment-experienced patients is scarce. To explore the effectiveness, safety, and costs of switching to a DTG plus RPV regimen in this population. This observational, prospective study included all treatment-experienced patients who switched to DTG plus RPV between November 2014 and July 2016. Patients were excluded if resistance mutations to integrase inhibitors or RPV were found. The effectiveness endpoint was the proportion of patients who achieved virological suppression (viral load [VL] 90% increased from 65.6% to 93.8% ( P = 0.004). The annual per-patient ART costs dropped by €665 ( P = 0.265). Switching to DTG plus RPV seems to be an effective and safe strategy. Significant improvements in patients' adherence and costs were achieved.

  5. Cost-Effectiveness of Dolutegravir in HIV-1 Treatment-Experienced (TE Patients in France.

    Full Text Available To evaluate the cost-effectiveness of a new generation integrase inhibitor (INI, dolutegravir (DTG, in France, in treatment-experienced (TE and INI-naïve HIV-infected adults with at least two classes resistance compared to raltegravir (RAL, by adapting previously published Anti-Retroviral Analysis by Monte Carlo Individual Simulation (ARAMIS model.ARAMIS is a microsimulation Markov model with a lifetime time horizon and a monthly cycle length. Health states are defined as with or without opportunistic infection and death. In the initial cohort, efficacy and safety data were derived from a phase III study comparing DTG to RAL. Antiretroviral treatment algorithms, accounting for patient history, were based on French guidelines and experts opinion. Costs are mainly including treatment costs, routine HIV and opportunistic infection care, and death. Utilities depend on CD4+ cell count and the occurrence of opportunistic infections.The ARAMIS model indicates in the TE population that DTG compared to RAL over a life time is associated with 0.35 additional quality-adjusted life years (QALY; 10.75 versus 10.41 and additional costs of €7,266 (€390,001 versus €382,735. DTG increased costs are mainly related to a 9.1-month increase in life expectancy for DTG compared with RAL, and consequently a longer time spent on ART. The incremental cost-effectiveness ratio (ICER for DTG compared with RAL is €21,048 per QALY gained. About 83% and 14% of total lifetime costs are associated with antiretroviral therapy and routine HIV care respectively. Univariate deterministic sensitivity analyses demonstrate the robustness of the model.DTG is cost-effective in the management of TE INI naive patients in France, from a collective perspective. These results could be explained by the superior efficacy of DTG in this population and its higher genetic barrier to resistance compared to RAL. These data need to be confirmed with longer-term real life data.

    Tipranavir, a non-peptidic protease inhibitor which shows in vitro efficacy against some HIV-1-resistant strains, can be used in salvage therapies for multi-experienced HIV patients due to its peculiar resistance profile including 21 mutations at 16 protease positions according to International AIDS Society (IAS). Other genotypic scores, however, which attribute a different weight to single amino-acid substitutions, have been recently proposed. To validate the clinical utility of four different genotypic scores for selecting tipranavir responders, the baseline resistance pattern of 176 HIV heavily experienced patients was correlated with virological success (HIV-RNA42.5% of patients. With univariate analysis, genotypic scores were all associated with outcome but showed a low accuracy with ROC analysis, with the weighted score (WS) by Scherer et al. demonstrating the best performance with an AUC of 68%. Only 52% of patients classified as susceptible (WSIAS mutations: L33F, I54AMV, Q58E, and non-IAS mutation: N37DES. On the contrary, the use of T20 in T20-naïve patients and the V82AFSI and F53LY non-IAS mutations were associated with virological success. The study suggests that even if the "weighted" scores are able to interpret correctly the antiretroviral resistance profile of multi-experienced patients, it is difficult to individuate a cut-off which can be easily applied to this population for discriminating responders.

    To describe the co-occurring symptoms (depression, fatigue, pain, sleep disturbance, and cognitive impairment), quality of life (QoL), and functional status in patients with high-grade glioma. Correlational, descriptive study of 73 participants with high-grade glioma in the U.S. Nine brief measures were obtained with a mailed survey. Participants were recruited from the online message board of The Healing Exchange BRAIN TRUST, a nonprofit organization dedicated to improving quality of life for people with brain tumors. Two symptom cluster models were examined. Four co-occurring symptoms were significantly correlated with each other and explained 29% of the variance in QoL: depression, fatigue, sleep disturbance, and cognitive impairment. Depression, fatigue, sleep disturbance, cognitive impairment, and pain were significantly correlated with each other and explained 62% of the variance in functional status. The interrelationships of the symptoms examined in this study and their relationships with QoL and functional status meet the criteria for defining a symptom cluster. The differences in the models of QoL and functional status indicates that symptom clusters may have unique characteristics in patients with gliomas.

    PURPOSE/OBJECTIVE: Patients (Pts) undergoing a I-125 or Pd-103 transperineal implant of the prostate (TPIP) experience urethritis of a varying degree. Most pts with mild to moderate symptoms can be treated with alpha blocking agents. Few pts will experience urethritis that does not respond to medical management, or persists beyond three half life's of the isotope. These pts will have significant quality of life complaints related to their symptoms. The purpose of this study is to present our results of Transurethral resection of the prostate (TURP) for patients with grade III urethritis. MATERIALS AND METHODS: Between November 1992 and January 1996, 378 patients underwent TPIP for clinically localized cancer. Treatment consisted of either a Pd-103 or I-125 implant either alone or in combination with external beam radiation and/or hormones. All the implants used a peripheral loading and urethral sparing technique. All pts were followed after the implant and assessed by DRE, PSA, and symptoms. The grading of urinary symptoms was as follows: Grade I-successful relief with pyridium or an equivalent medication, Grade II-pts requiring various doses of alpha blockers, Grade III-pts with persistent symptoms despite medical management. RESULTS: Of the 378 pts undergoing implant, 358 had sufficient follow-up to be included in this review. Forty two pts (12%) received hormone downsizing prior to implantation. Two hundred and two (56%) underwent a Pd-103 implant and 156 (44%) a I-125 implant; 15 underwent EBRT plus I-125 and 27 with EBRT and Pd-103. One hundred and fifty five (43%) pts experienced grade I urethritis during the first three half life's of the implant, while 116 (32%) experienced grade II urethritis. Twenty eight pts (8%) experienced grade III urethritis that persisted beyond three half life's of the implant. All grade III pts were offered TURP and 26 elected to undergo this procedure. Of the twenty six pts undergoing TURP, 100% experienced relief of their

    To determine the histological grading patterns in a cohort of hospitalized patients of cutaneous leishmaniasis. One hundred patients of Cutaneous Leishmaniasis (CL), admitted in dermatology wards at PNS Shifa Hospital, Karachi, were examined. Only admitted patients of all ages and both sexes were included in the study. Patients of CL, who had received or were receiving systemic treatment were excluded. The lesions having marked secondary bacterial infection were also excluded. Initial diagnosis was clinical. History of being to an endemic area supported the diagnosis. The lesions were divided in two groups. Early, with duration less than 03 months and late, with duration between 3 and 12 months. The clinical lesions were noted as nodules, plaques, ulcers, crusted ulcers, lupoid lesions and plaques with scarring. Three types of skin smears (slit skin smear, saline aspirate smear and dab smear) were taken and examined with Giemsa stain. Cultures were performed on Nicolle-Novy-MacNeal (NNN) culture medium from Defense Scientific and Technology Organization (DESTO) Lab., Pakistan. Incisional skin biopsies were done. The biopsy specimens were examined by hemotoxylin and eosin stain (H and E stain). The number of Leishmania Tropica (LT) bodies was graded according to modified Ridley's parasitic index 1983. Clinical features were correlated with the histological patterns. Five histological patterns were identified in current study: 1) diffuse dermal infiltration without necrosis, 2) patchy dermal infiltration, 3) diffuse dermal infiltration with necrosis, 4) early reactive granuloma formation and 5) established epithelioid granuloma formation. LT bodies were identified in 75% of cases. Epidermal features were non-specific. The early lesions presented with diffuse infiltrate and late lesions showed granuloma formation. Five distinct types of histological patterns of CL have been recognized in this study. The early lesions presented with diffuse infiltrate and late lesions

    Disclosure is a prerequisite to receive disease-specific social support. However, in the case of a stigmatised disease, it can also lead to discrimination. We aimed to assess disclosure rates of HIV patients and the reactions they encountered in comparison to patients with chronic viral hepatitis or diabetes mellitus and patients' general perception of disease-specific discrimination. We constructed a self-report questionnaire, anonymously assessing the size of the social environment, the persons who had been informed, and the experienced reactions as perceived by the disclosing patients, to be rated on 1-4 point Likert scales. In addition, patients were asked whether they perceive general discrimination in Germany. One hundred and seventy-one patients were asked to participate. Five rejected, thus questionnaires from 83 patients with HIV, 42 patients with chronic viral hepatitis B (n = 9) or C (n = 33), and 41 patients with insulin-dependent diabetes mellitus (type I n = 14, type II n = 27) were analysed. Whereas the size of the social environment did not differ, HIV-infected patients were least likely to disclose their disease (60.7%, SD ± 31.9) to their social environment as compared to patients with chronic viral hepatitis (84.2 ± 23.3%, pdiabetes mellitus (94.4 ± 10.3%, ppatient group, the mean disclosure rate was highest to partners (90.9%), followed by the public environment (65.2%), friends (59.4%) and family members (43.8%). HIV patients experienced supportive reactions after 79.3 ± 26.4% of disclosures, which was the case in 91.4 ± 19.6% and 75.7 ± 36.1% of patients with hepatitis or diabetes mellitus, respectively. 69.5% of HIV patients stated to perceive general discrimination in Germany. We conclude that HIV patients had experienced supportive reactions after the majority of disclosures, but the low rate points out that their information strategy had been very selective. Societal discrimination of HIV patients is still an issue and needs to be

    The aim of this study was to present the surgical findings of children with Waardenburg syndrome (WS) and investigate speech development after cochlear implantation in this unique group of patients. A retrospective chart review of the patients diagnosed with WS and implanted between 1998 and 2015 was performed. Categories of auditory performance (CAP) test were used to assess the auditory skills of these patients. CAP is a nonlinear hierarchical scale used to rate a child's developing auditory abilities. Preoperative test results and intraoperative surgical findings of these patients have been presented. In total, 1835 cases were implanted a tour institution, and 1210 of these were children. Among these implantees, 11 were diagnosed with WS (0.59% of all implantees). Four of the 11 patients showed incomplete partition type 2bony labyrinth abnormality (Mondini deformity) and all patients showed intraoperative gusher during cochleostomy, which was subsided through routine interventions. No other complications occurred during surgery, and all patients showed satisfactory CAP results in the late postoperative period. Our experiences with cochlear implantation in patients with WS showed that the procedure is safe and effective in this group of patients. Surgeons should be aware of possible labyrinth malformations and intraoperative problems such as gusher in these patients. In long term, auditory performances may exhibit satisfactory results with optimal postoperative educational and supportive measures.

    Safety-net patients' socioeconomic barriers interact with limited digital and health literacies to produce a "knowledge gap" that impacts the delivery of healthcare via telehealth technologies. Six focus groups (2 African- American and 4 Latino) were conducted with patients who received teleretinal screening in a U.S. urban safety-net setting. Focus groups were analyzed using a modified grounded theory methodology. Findings indicate that patients' knowledge gap is primarily produced at three points during the delivery of care: (1) exacerbation of patients' pre-existing personal barriers in the clinical setting; (2) encounters with technology during screening; and (3) lack of follow up after the visit. This knowledge gap produces confusion, potentially limiting patients' perceptions of care and their ability to manage their own care. It may be ameliorated through delivery of patient education focused on both disease pathology and specific role of telehealth technologies in disease management.

    Inappropriate shocks (IASs) from implantable cardioverter defibrillators (ICDs) are associated with decreased quality of life, but whether they increase healthcare utilization and treatment costs is unknown. We sought to determine the impact of IASs on subsequent healthcare utilization and treatment costs. We conducted a case-control analysis of ICD patients at a single institution from 1997 to 2010 and who had ≥12 months of post-ICD implant follow-up. Cases included all patients experiencing an IAS during the first 12 months after implantation. Eligible control patients did not receive a shock of any kind during the 12 months after implantation. Propensity scores based on 36 covariates (area under curve = 0.78) were used to match cases to controls. We compared the rate (occurrences/person year [PY]) of healthcare utilization immediately following IAS to the end of the 12-month follow-up period to the rate in the no-shock group over 12 months of follow-up. We also compared 12-month postimplant treatment (outpatient clinic, emergency room, and hospitalization) costs in both groups. A total of 76 patients experiencing ≥1 IAS during the first 12 months after implant (contributing 48 PYs) were matched to 76 no-shock patients (contributing 76 PYs). Cardiovascular (CV)-related clinic visit and hospitalization rates were increased following an IAS compared to those not receiving a shock (4.0 vs 3.3 and 0.7 vs 0.5, respectively, P = 0.02 for both). CV-related emergency room visitation (0.15 vs 0.08) rates were also numerically higher following an IAS, but did not reach statistical significance (P = 0.26). Patients experiencing an IAS accrued greater treatment costs during the 12 months postimplant compared to no-shock patients ($13,973 ± $46,345 vs $6,790 ± $19,091, P = 0.001). Recipients of IAS utilize the healthcare system more frequently following an IAS than patients not experiencing a shock. This increased utilization results in higher costs of treating IAS

    Pubertal onset and sexual development are usually normal in 47, XXX individuals; however, we report two cases of premature ovarian failure (POF) in infertile women with trisomy X. Chromosome analysis was conducted with G-banding and fluorescence in situ hybridization using X- and Y-bearing probe. Hormonal administration was primarily Kaufmann's treatment or long-term estradiol treatment, followed by withdrawal bleeding from estrogen and progesterone. Two patients with trisomy X, aged 31 (patient 1) and 27 years (patient 2), were diagnosed with POF due to hypergonadotropic hypogonadism. Their ovaries were small. Patient 1 had a FSH level of 44.6 mIU/ml and patient 2 had a FSH level of 74.6 mIU/ml. In patient 1, with Kaufmann's treatment, the FSH decreased to 13.5 mIU/ml; however, follicle growth did not occur following HMG stimulation. In patient 2, FSH did not decrease despite Kaufmann's treatment; therefore, she was given a GnRH agonist and her FSH level decreased to 7.1 mIU/ml. However, her ovaries never responded to HMG stimulation. We report on two patients with a 47, XXX karyotype who became infertile due to POF. We recommend that when a patient is diagnosed with trisomy X, the possibility of POF must be strongly considered.

    We evaluated the effectiveness of a raltegravir (RAL)-containing regimen plus an optimized background regimen in HIV-1 highly treatment-experienced patients. A retrospective cohort, multicentre study was conducted. Adult (>16 years old) HIV treatment-experience patients starting therapy with a RAL-containing regimen were included. Effectiveness was evaluated as the percentage of patients with an undetectable HIV-1 RNA viral load (treatment failure. Of the 107 patients in the cohort, 86% were men, the median age was 45 years [interquartile range (IQR) 40-52] and the median number of previous regimens was six (IQR 4-7). After 48 weeks of treatment, 73% (IQR 63-80%) of patients (n = 78) had a viral load of HIV-1 RNA of 40 years [odds ratio (OR) 5.61; 95% confidence interval (CI) 1.61-18.84; P = 0.006] and use of tenofovir in the regimen (OR 0.16; 95% CI 0.03-0.80; P = 0.026). In this Mexican cohort, RAL achieved high rates of virological suppression and an increase in CD4+ cell count in highly treatment-experienced patients infected with HIV-1. Age >40 years was associated with a good virological outcome, contrary to tenofovir use, which was associated with a poor virological outcome.

    The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. The median follow up duration was 16.2 months (range: 1.0-124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC. © 2018 Wiley Periodicals, Inc.

    Various studies have assessed patient satisfaction with topical versus peribulbar anesthesia with conflicting results. Aim of study was to determine satisfaction level in same patient who gets topical anesthesia in one eye and peribulbar block in another eye. We propose that evaluation of various indicators of patient satisfaction will enable better selection of cases for topical anesthesia in the future. Eighty patients scheduled for phacoemulsification were enrolled in prospective, randomized, double-blind study. Each patient scheduled twice for one eye under topical anesthesia and other in peribulbar block. Pain, discomfort and pressure during application of local anesthetic, during phacoemulsification and at 2 hours after procedure were assessed on standard scales. Before discharge patient satisfaction level was checked with Iowa satisfaction with anesthesia scale (ISAS). The Student's t-test was used to determine the significance of IOWA score in both groups. Ptopical anesthesia were all significantly lower compared to peribulbar anesthesia (P=0.004, 0.000, 0.002, respectively). In contrast, intraoperative scores were significantly higher in the topical anesthesia group compared to peribulbar anesthesia (P=0.022, 0.000, 0.000, respectively). Patient satisfaction measured with ISAS shows that peribulbar anesthesia with P=0.000 is strongly significant. Peribulbar anesthesia provided significantly better patient satisfaction in comparison with topical anesthesia when used for cataract surgery.

    The aim of our work is to present the universality of burnout syndrome among physicians worldwide and to demonstrate selected aspects of the relationship between patients and doctors as a common factor predisposing to burnout. We looked up 20 original pieces of research from the Medline database published in the last 10 years to determine the prevalence of burnout among doctors in different countries. In all quoted works a remarkable percentage of doctors of interventional and non-interventional specialties suffered burnout. Because it is the relationship with patients that constitutes a key denominator for their work, in the discussion we have exposed an important aspect of it, destructive patient games, described on the basis of transactional analysis. Since universal burnout causes a deterioration of doctors' service, for the optimal good of the patient to survive preservation of the doctor's well-being in the patient-doctor relationship is needed everywhere.

    The present study was designed to evaluate the effectiveness of audiovisual stimulation on the state of the eye accommodation system in the patients experiencing eyes train with the concomitant disturbances of psychological. It was shown that a course of audiovisual stimulation (seeing a psychorelaxing film accompanied by a proper music) results in positive (5.9-21.9%) dynamics of the objective accommodation parameters and of the subjective status (4.5-33.2%). Taken together, these findings whole allow this method to be regarded as "relaxing preparation" in the integral complex of the measures for the preservation of the professional vision in this group of the patients.

    Maintaining stable levels of anticoagulation using warfarin therapy is challenging. Few studies have examined the stability of the international normalized ratio (INR) in patients with nonvalvular atrial fibrillation (NVAF) who have had ≥6 months' exposure to warfarin anticoagulation for stroke prevention. Our objective was to describe INR control in NVAF patients who had been receiving warfarin for at least 6 months. Using retrospective patient data from the CoagClinic™ database, we analyzed data from NVAF patients treated with warfarin to assess the quality of INR control and possible predictors of poor INR control. Time within, above, and below the recommended INR range (2.0-3.0) was calculated for patients who had received warfarin for ≥6 months and had three or more INR values. The analysis also assessed INR patterns and resource utilization of patients with an INR >4.0. Logistic regression models were used to determine factors associated with poor INR control. Patients (n = 9433) had an average of 1.6 measurements per 30 days. Mean follow-up time was 544 days. Approximately 39% of INR values were out of range, with 23% of INR values being 3.0. Mean percent time with INR in therapeutic range was 67%; INR 3.0 was 14%. Patients with more than one reading of INR >4.0 (~39%) required an average of one more visit and took 3 weeks to return to an in-range INR. Male sex and age >75 years were predictive of better INR control, whereas a history of heart failure or diabetes were predictive of out-of-range INR values. However, patient characteristics did not predict the likelihood of INR >4.0. Out-of-range INR values remain frequent in patients with NVAF treated with warfarin. Exposure to high INR values was common, resulting in increased resource utilization.

    Recently, we proposed a model explaining the origin of fatigue in multiple sclerosis (MS) patients. This model assumes that the feeling of fatigue results from inflammation-induced information processing within interoceptive brain areas. To investigate the association between self-reported cognitive fatigue and structural integrity of interoceptive brain areas in MS patients. 95 MS patients and 28 healthy controls participated in this study. All participants underwent diffusion tensor MRI and fractional anisotropy data were calculated for the amygdala, the stria terminalis and the corpus callosum, a non-interoceptive brain area. Based on the cognitive fatigue score of the Fatigue Scale for Motor and Cognition, patients were divided into moderately cognitively fatigued (cognitive fatigue score ≥ 28) and cognitively non-fatigued (cognitive fatigue score < 28) MS patients. Healthy controls were recruited as a third group. Repeated measures analyses of covariance, controlling for age, depression and brain atrophy, were performed to investigate whether the factor Group had a significant effect on the fractional anisotropy data. A significant effect of Group was observed for the amygdala (F = 3.389, p = 0.037). MS patients without cognitive fatigue presented lower values of the amygdala than MS patients with cognitive fatigue and healthy controls. For the stria terminalis and the corpus callosum, no main effect of Group was observed. The structural integrity of the amygdala in non-fatigued MS patients appears to be reduced. According to our model this might indicate that the absence of fatigue in non-fatigued MS patients might result from disturbed inflammation-induced information processing in the amygdala.

    In this study we aimed to develop a theoretical account of the experienced benefit of psychomotor therapy in addition to treatment as usual in patients with chronic shoulder pain. The qualitative study design was based on a grounded theory approach. Open-ended face-to-face interviews were conducted after treatment was completed. We generated data and performed analyses by constant comparative analysis and theoretical sampling that focused on the patients' behavioural characteristics related to the experienced benefit of psychomotor therapy. We conducted 12 interviews, eight of which were with men. "Regaining capability" emerged as representative of the pattern of behaviour. Through this pattern, the patients resolved concern about losing capability. Regaining capability involved three behavioural typologies: taking advice, minding the body, and encompassing life changes. The patients' behavioural typologies revealed different levels of life changes. Psychomotor therapy offered the patients in our study new and better ways of coping with their shoulder pain.

Data are presented on 34 patients. 11 patients had tenofovir added to a stable anti-retroviral treatment (ART) and 23 patients had drugs other than tenofovir. CD4 counts, HIV......-RNA levels and genotypic resistance were determined at baseline and after 3 and 6 months. After initiation of tenofovir treatment, a mean decrease in HIV-RNA for all 34 patients was observed (-0.43 log1o copies/ml (+/- 1.22) and -0.49 log10 copies/ml (+/- 1.36) after 3 and 6 months, respectively, (p = 0...... initiation of tenofovir treatment, no significant increases in CD4 count were observed. All new NRTI-associated mutations could be explained by the background treatment. In conclusion, we observed a significant decrease in HIV-RNA only when tenofovir was prescribed, in conjunction with other anti...

    Darunavir (DRV) is a preferred agent in treatment guidelines for ART-naïve and experienced patients [1]. It is considered to have a high genetic barrier to resistance and 11 resistance-associated mutations (RAMs) are recognized by IAS-USA [2]. These have largely been identified by analyses examining the correlation between baseline genotype and virological response [3]. However, there is little information on RAMs that are directly selected by DRV, outside of short-term clinical trials. We aimed to identify emerging mutations by comparing the genotypes of individuals before and after DRV exposure. The UK HIV Drug Resistance Database was used to identify patients aged over 16 who had received at least 30 days of a DRV-containing regimen. Patients were included if they had a "baseline" resistance test, prior to DRV exposure, and a "repeat" test, either on DRV or within 30 days of stopping this agent. To avoid attributing the effects of other PIs on emerging RAMs to DRV, patients were excluded if they had received another PI for greater than 90 days between the baseline genotype and the start of DRV. The baseline and repeat tests were compared to determine the nature of mutations stratified by PI history. A total of 5623 patients had DRV, of whom 306 met the inclusion criteria. A total of 228 (74.5%) were male, median age at the start of DRV was 42 years (IQR 37-47), and half had subtype B infection. The mode of transmission was homosexual contact for 50%, heterosexual for 38%, and 3% were injection drug users. The median CD4 count at the start of DRV was 257 cells/mm(3) (IQR 94-453). A total of 149 patients (49%) had a history of PI use prior to DRV, and 157 (51%) were PI-naïve. The most common previous PIs were lopinavir, atazanavir, and saquinavir. Baseline DRV RAMs were present in 1 (0.6%) PI-naïve and 20 (13.4%) PI-experienced patients. Mutations emerged under DRV pressure in a further 3 (1.9%) PI-naïve patients, and in 7 (4.7%) PI-experienced patients, 5 of

    Full Text Available Purpose: The present study aimed at clinical and pulmonary functions profiling of patients with chronic obstructive pulmonary disease (COPD to anticipate future exacerbations. Methods: The study included 80 COPD patients; 40 patients had ≥2 acute exacerbations during preceding 1 year (frequent exacerbation [FECOPD] group and 40 patients had <2 acute exacerbations during preceding 1 year (infrequent exacerbation [I-FECOPD] group. Clinical profile, sputum microbiology, blood gas analysis, spirometric indices, and diffusion capacity (transfer test variables were assessed. Groups' comparison was performed using an independent t-test for numeric scale parameters and Chi-square test for nominal parameters. Pearson's and Spearman's correlation coefficients were derived for numeric scale parameters and numeric nominal parameters, respectively. Multinomial logistic regression analysis was done using SPSS software. Results: FECOPD group contained younger patients than in I-FECOPD group although the difference was not statistically significant. There was no significant difference between two groups regarding smoking pack-years and duration of illness. FECOPD group had significantly more expectoration score and Modified Medical Research Council dyspnea scores. Cough score and wheeze score did not differ significantly between two groups. More patients in FECOPD group (12/40 vs. 4/40 had lower airway bacterial colonization. Arterial blood gas parameters were more deranged in FECOPD group. Spirometric indices (forced expiratory volume during 1st s as well as transfer test (both diffusing capacity for carbon monoxide and transfer coefficient of the lung values were significantly reduced in FECOPD group. Conclusions: The patients in FECOPD group had clinical, spirometric, and transfer test profiling suggestive of a severe COPD phenotype, the recognition will help in predicting future exacerbations and a better management.

    Many stroke survivors will be cared for at home, primarily by their relatives. Providing care to a family member with a chronic disabling disease can be both emotionally and physically distressing for the caregivers. The purpose of this study was to investigate the relationship between patients' characteristics, duration of caregiving, daily caregiving time, caregiver's characteristics, caregiver depression and burden in caregivers of patients with stroke. A cross-sectional design was used with a convenience sample of 116 subjects. The Center of Epidemiologic Studies of Depression and the Caregiver Strain Index were used to identify caregiver depression and burden, respectively. Logistic regression analysis identified the influence of independent variables on caregiver depression and caregiver burden. Caregivers had high scores for depression and burden indices. Caregivers' health, receiving professional home health care and caregivers' burden were related to caregiver depression. Functional disabilities of patients with stroke and depression of caregivers were related to caregiver burden. To decrease caregiver depression and burden, nurses must provide caregivers with instructions for home management of patients with stroke. Development of specialized stroke home health services in Jordan that targets patients with stroke and their caregivers are recommended. © 2012 Blackwell Publishing Asia Pty Ltd.

    Objective Numerous studies on the effects of seclusion and/or restraint in acute psychiatric treatment have reported both positive and negative effects. However, no studies to date have evaluated the effects of seclusion and/or restraint on schizophrenia patients using a rating scale. Thus, to examine the effects of seclusion and/or restraint on schizophrenia patients, we used the Brief Psychiatric Rating Scale and assessed the psychological condition of patients. Methods Factor analysis was conducted to create subscales of Brief Psychiatric Rating Scale, and psychiatric changes were assessed with respect to each subscale using multiple logistic regression analyses. Analyses were performed on three groups (i.e. entire, higher functioning, and lower functioning groups) involving a total of 1559 schizophrenia patients aged 18 to 65 years. Results In the entire and lower functioning groups, seclusion was a significant predictor of improvements related to the "hostility/suspiciousness" subscale. Seclusion combined with restraint was associated with improvements related to the "psychosis/thinking disorder" subscale. In the higher functioning group, there were no significant predictors. Conclusions It is implied that seclusion and/or restraint is related to improved psychiatric symptoms only among patients whose functioning is impaired. To verify the present findings, further studies involving multiple sites and additional psychiatric measures are necessary.

    It is important to identify, from the patients' perspectives, the different factors that contribute toward psycho-social-spiritual healing. This was a qualitative study that took place at a large research center, an underserved clinic, and a community hospital. We used a needs assessment questionnaire and open-ended questions to assess the constituents of psycho-social-spiritual healing: (I) how previous life experiences affected patients' present situations in dealing with their illnesses; (II) barriers to palliative care, and (III) benefits of palliative care. Of a total of 30 participants from 3 different study sites, 24 (80%) were receiving inpatient or outpatient palliative care at a research center. Thirteen (43%) participants were female, 10 (33%) were Black/African American, and 16 (53%) reported being on disability. While the initial shock of the diagnosis made participants feel unprepared for their illnesses, many looked to role models, previous work experiences, and spiritual as well as religious support as sources of strength and coping mechanisms. Barriers to palliative care were identified as either external (lack of proper resources) or internal (symptom barriers and perceived self-limitations). The feeling of "being seen/being heard" was perceived by many participants as the most beneficial aspect of palliative care. The needs assessment questionnaire and open-ended questions presented in this study may be used in clinical settings to better help patients achieve psycho-social-spiritual healing through palliative care and to help clinicians learn about the person behind the patient.

    To investigate the impact of the number of previous infertility treatment failures on anxiety and depression. In a cross-sectional study, individuals (men and women, but not couples) aged at least 18 years who had a history of infertility and could read and write in Persian were enrolled at the Royan Institute, Tehran, Iran, between November 1, 2013, and February 28, 2014. Participants provided demographic and infertility information and completed the Persian version of the Hospital Anxiety and Depression Scale (HADS). Overall, 330 patients (122 men, 208 women) were included. Mean scores on the HADS anxiety and depression subscales (HADS-A and HADS-D) were 8.40±4.51 and 5.95±3.54, respectively. In multiple regression analysis, mean HADS-A scores were significantly higher for patients with one treatment failure (9.57±4.58) than for those without a history of treatment (7.79±4.13; P=0.003). HADS-D scores were significantly higher for patients with two failures (6.92±3.69) than for those with no previous treatment (5.59±3.79; P=0.019). Patients with infertility have increased depression and anxiety after infertility treatment failure. Counseling or treatment for these potential psychological effects should be considered after infertility treatment failure. Copyright © 2015 International Federation of Gynecology and Obstetrics.

    Full Text Available Patients perceive the intensive care unit (ICU as being a stressful and anxiety-provoking environment. The physiological effects of stress and anxiety are found to be harmful and therefore should be avoided in cardiac surgery patients. The aim of the study on which this article is based was to describe cardiac surgery patients’ experiences of music as a therapeutic intervention in the ICU of a public hospital. The objectives of this article were to introduce and then expose the cardiac patients to music as part of their routine postoperative care and to explore and describe their experiences of the music intervention. The findings of the research are to be the basis for making recommendations for the inclusion of music as part of the routine postoperative care received by cardiac surgery patients in the ICU. A qualitative research methodology, using a contextual, explorative and descriptive research design, was adopted. The population of the study was cardiac surgery patients admitted to the ICU of a public hospital. An unstructured interview was conducted with each participant and content analysis and coding procedures were used to analyse the data. Four main themes were identified in the results, namely practical and operational aspects of the music sessions; participants’ experiences; discomfort due to therapeutic apparatus and the ICU environment; and the role of music and recommendations for music as a therapeutic intervention. Participants’ experiences were mainly positive. Results focused on experiences of the music and also on the participants’ experiences of the operational aspects of the therapy, as well as factors within and around the participants.

    Full Text Available Background. Right ventricular (RV dysfunction during cancer therapy related cardiotoxicity and its prognostic implications have not been examined. Aim. We sought to determine the incidence and prognostic value of RV dysfunction at time of LV defined cardiotoxicity. Methods. We retrospectively identified 30 HER2+ female patients with breast cancer treated with trastuzumab (± anthracycline who developed cardiotoxicity and had a diagnostic quality transthoracic echocardiography. LV ejection fraction (LVEF, RV fractional area change (RV FAC, and peak systolic longitudinal strain (for both LV and RV were measured on echocardiograms at the time of cardiotoxicity and during follow-up. Thirty age balanced precancer therapy and HER2+ breast cancer patients were used as controls. Results. In the 30 patients with cardiotoxicity (mean ± SD age 54 ± 12 years RV FAC was significantly lower (42 ± 7 versus 47 ± 6%, P=0.01 compared to controls. RV dysfunction defined by global longitudinal strain (GLS < −20.3% was seen in 40% (n=12. During follow-up in 16 out of 30 patients (23 ± 15 months, there was persistent LV dysfunction (EF < 55% in 69% (n=11. Concomitant RV dysfunction at the time of LV cardiotoxicity was associated with reduced recovery of LVEF during follow-up although this was not statistically significant. Conclusion. RV dysfunction at the time of LV cardiotoxicity is frequent in patients with breast cancer receiving trastuzumab therapy. Despite appropriate management, LV dysfunction persisted in the majority at follow-up. The prognostic value of RV dysfunction at the time of cardiotoxicity warrants further investigation.

    Full Text Available Objective: To analyze the procedures to manage tuberculous meningitis (TM employed in a third level hospital. Methods: A descriptive study was carried out on the procedures used to manage TM in 532 children attended at the Infectology Service of National Institute of Pediatrics of Mexico City. Patients included must have analysis of cerebrospinal fluid suggestive of TM and negative for other bacteria among others criteria. Results: The predominant signs observed were fever in 486 patients, apathy in 485, somnolence in 477, headache in 173, seizure crisis in 400 and coma progression in 17. Cerebrospinal fluid showed an average of 199 cells/mL, proteins 170.8 mg. Chest X-ray showed abnormalities in 330 cases and brain tomography revealed basal arachnoiditis in 306 cases. 24 patients died and 414 of them had audition and epileptic sequels. Conclusions: TM has continued to be a serious health problem in developing countries. Delay in diagnosis of this disease is a cause of the increase not only of its morbidity but also its mortality as well as its sequels.

    Full Text Available Background. Little is known about temporal trends in frequencies of clinically relevant ARV resistance mutations in HIV strains from U.S. patients undergoing genotypic testing (GT in routine HIV care. Methods. We analyzed cumulative frequency of HIV resistance among patients in the HIV Outpatient Study (HOPS who, during 1999–2008 and while prescribed antiretrovirals, underwent GT with plasma HIV RNA >1,000 copies/mL. Exposure ≥4 months to each of three major antiretroviral classes (NRTI, NNRTI and PI was defined as triple-class exposure (TCE. Results. 906 patients contributed 1,570 GT results. The annual frequency of any major resistance mutations decreased during 1999–2008 (88% to 79%, P=0.05. Resistance to PIs decreased among PI-exposed patients (71% to 46%, P=0.010 as exposure to ritonavir-boosted PIs increased (6% to 81%, P<0.001. Non-significant declines were observed in resistance to NRTIs among NRTI-exposed (82% to 67%, and triple-class-resistance among TCE patients (66% to 41%, but not to NNRTIs among NNRTI-exposed. Conclusions. HIV resistance was common but declined in HIV isolates from subgroups of ARV-experienced HOPS patients during 1999–2008. Resistance to PIs among PI-exposed patients decreased, possibly due to increased representation of patients whose only PI exposures were to boosted PIs.

    Early treatment failure (ETF) in follicular lymphoma (FL), defined as relapse or progression within 2 years of frontline chemoimmunotherapy, is a newly recognized marker of poor survival and identifies a high-risk group of patients with an expected 5-year overall survival (OS) rate of approximately 50%. Transplantation is an established option for relapsed FL, but its efficacy in this specific ETF FL population has not been previously evaluated. This study compared autologous hematopoietic stem cell transplantation (auto-HCT) with either matched sibling donor (MSD) or matched unrelated donor (MUD) allogeneic hematopoietic cell transplantation (allo-HCT) as the first transplantation approach for patients with ETF FL (age ≥ 18 years) undergoing auto-HCT or allo-HCT between 2002 and 2014. The primary endpoint was OS. The secondary endpoints were progression-free survival, relapse, and nonrelapse mortality (NRM). Four hundred forty FL patients had ETF (auto-HCT, 240; MSD hematopoietic stem cell transplantation [HCT], 105; and MUD HCT, 95). With a median follow-up of 69 to 73 months, the adjusted probability of 5-year OS was significantly higher after auto-HCT (70%) or MSD HCT (73%) versus MUD HCT (49%; P = .0008). The 5-year adjusted probability of NRM was significantly lower for auto-HCT (5%) versus MSD (17%) or MUD HCT (33%; P ETF, undergoing auto-HCT for FL have low NRM and a promising 5-year OS rate (70%). MSD HCT has lower relapse rates than auto-HCT but similar OS. Cancer 2018. © 2018 American Cancer Society. © 2018 American Cancer Society.

    This study contributes towards a better understanding of learning dynamics in doctoral supervision by analysing how learning opportunities are created in the interaction between supervisors and PhD students, using the notion of experiencing variation as a key to learning. Empirically, we have based...... the study on four video-recorded sessions, with four different PhD students and their supervisors, all from life sciences. Our analysis revealed that learning opportunities in the supervision sessions concerned either the content matter of research (for instance, understanding soil structure......), or the research methods— more specifically how to produce valid results. Our results illustrate how supervisors and PhD students create a space of learning together in their particular discipline by varying critical aspects of their research in their discussions.

    Grade {>=}3 radiation pneumonitis (RP) is generally severe and life-threatening. Predictors of grade {>=}2 are usually used for grade {>=}3 RP prediction, but it is unclear whether these predictors are appropriate. In this study, predictors of grade {>=}2 and grade {>=}3 RP were investigated separately. The increased risk of severe RP in elderly patients compared with younger patients was also evaluated. Material and methods: A total of 176 consecutive patients with locally advanced non-small cell lung cancer were followed up prospectively after three-dimensional conformal radiotherapy. RP was graded according to Common Terminology Criteria for Adverse Events version 3.0. Results: Mean lung dose (MLD), mean heart dose, ratio of planning target volume to total lung volume (PTV/Lung), and dose-volume histogram comprehensive value of both heart and lung were associated with both grade {>=}2 and grade {>=}3 RP in univariate analysis. In multivariate logistic regression analysis, age and MLD were predictors of both grade {>=}2 RP and grade {>=}3 RP; receipt of chemotherapy predicted grade {>=}3 RP only; and sex and PTV/Lung predicted grade {>=}2 RP only. Among patients who developed high-grade RP, MLD and PTV/Lung were significantly lower in patients aged {>=}70 years than in younger patients (p<0.05 for both comparisons). Conclusions: The predictors were not completely consistent between grade {>=}2 RP and grade {>=}3 RP. Elderly patients had a higher risk of severe RP than younger patients did, possibly due to lower tolerance of radiation to the lung.

    mHealth systems are becoming more common to aid patients in their diabetes self-management, but recent studies indicate a need for thorough evaluation of patients' experienced usability. Current evaluations lack a multi-method design for data collection and structured methods for data analyses. The purpose of this study was to provide a feasibility test of a multi-method approach for both data collection and data analyses for patients' experienced usability of a mHealth system for diabetes type 2 self-management. A random sample of 10 users was selected from a larger clinical trial. Data collection methods included user testing with eight representative tasks and Think Aloud protocol, a semi-structured interview and a questionnaire on patients' experiences using the system. The Framework Analysis (FA) method and Usability Problem Taxonomy (UPT) were used to structure, code and analyze the results. A usability severity rating was assigned after classification. The combined methods resulted in a total of 117 problems condensed into 19 usability issues with an average severity rating of 2.47 or serious. The usability test detected 50% of the initial usability problems, followed by the post-interview at 29%. The usability test found 18 of 19 consolidated usability problems while the questionnaire uncovered one unique issue. Patients experienced most usability problems (8) in the Glucose Readings View when performing complex tasks such as adding, deleting, and exporting glucose measurements. The severity ratings were the highest for the Glucose Diary View, Glucose Readings View, and Blood Pressure View with an average severity rating of 3 (serious). Most of the issues were classified under the artifact component of the UPT and primary categories of Visualness (7) and Manipulation (6). In the UPT task component, most issues were in the primary category Task-mapping (12). Multiple data collection methods yielded a more comprehensive set of usability issues. Usability

    Neuropathic pain is a disabling chronic condition with limited therapeutic options. Few studies have addressed patient's experience and strategies. The aim of this study was to explore dilemmas experienced in order to improve care and rehabilitation. An interview study with 39 patients suffering from neuropathic pain of different origin was performed. We used the critical incident technique to collect data. Questions on occasions when patients had been hindered by or reminded of their neuropathic pain were included, and the self-perceived consequences and management of such occasions. The interviews were transcribed verbatim and analysed qualitatively. A broad range of experiences categorised into dilemmas, disturbances, consequences and managements from most parts of everyday life was identified. The dilemmas were 'housework', 'sitting', 'physical activity', 'personal hygiene', 'sleeping difficulties', 'hypersensitivity to external stimuli', 'social relationships', 'transportation' and 'leisure time'. Disturbances were 'failures', 'inabilities' and 'restrictions'. Consequences were 'increased pain', 'psychological reactions' and 'physical symptoms'. The majority of the patients used activity-oriented strategies to manage their pain such as alternative ways of performing the task, a cognitive approach or simply ignoring the pain. This is one of the first studies presenting detailed data on everyday dilemmas, disturbances and consequences of patients with chronic neuropathic pain. Such information is important in clinical settings to improve care and rehabilitation.

    Supratentorial gangliogliomas (GGs) are rare tumors of the central nervous system and are commonly associated with chronic seizures. To date, only case reports and small series of patients with short-term follow-up have been available for the assessment of the potential of GGs to recur and progress. Data from 184 patients who underwent resection of GGs between 1988 and 2001 were available from the University of Bonn Epilepsy Surgery Center (Bonn, Germany). Analysis of factors that influenced tumor recurrence and patient survival, such as preoperative history, age at operation, tumor location, histopathologic findings (including immunohistochemical findings), extent of tumor resection, and recurrence evaluated on postoperative magnetic resonance imaging (MRI), was performed. The median follow-up period was 8 years (range, 1-14 years). One hundred seventy-eight patients (97%) presented with long-term seizures (> or = 2 years). The median age at surgery was 26 years (range, 2-65 years). Tumor location was temporal in 79% of patients and frontal in 12% of patients. Eleven tumors (6%) were classified as World Health Organization (WHO) Grade 2 lesions, and 2 tumors were classified as anaplastic WHO Grade 3 lesions. For 38 patients (21%), postoperative MRIs revealed residual tumors. Two years after surgery, 5 patients (3%) experienced tumor recurrence, which resulted in malignant progression in 3 patients (2%) and death in 2 patients (1%). Eighty-four percent of patients with epilepsy had complete and sustained seizure relief. The calculated 7.5-year recurrence-free survival rate was 97%. Lower rates of recurrence were found in patients with tumors classified as WHO Grade 1 lesions (P < 0.0001), patients with temporal lesions (P < 0.0001), patients who underwent complete tumor resection (P = 0.0278), and patients with long-standing epilepsy (P < 0.0001). Supratentorial GGs are benign tumors, and the surgical goal for patients with GG should be complete resection. Residual

    2018-01-01

    Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. These questions take on a particular importance in philosophy for two reasons. Firstly, there is a view concerning the metaphysics of time, known as the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Instead, the world is a four-dimensional space-time block, lacking any of the apparent dynamic features of time. If the B-theory is correct, as the book argues, then it must be explained why ...

    Understanding the difficulties faced by different migrant groups is vital to address disparities and inform targeted health-care service delivery. Migrant oncology patients experience increased morbidity, mortality and psychological distress, with this tentatively linked to language and communication difficulties. The objective of this exploratory study was to investigate the communication barriers and challenges experienced by Arabic, Greek and Chinese (Mandarin and Cantonese) speaking oncology patients in Australia. This study employed a cross-sectional design using patient-reported outcome survey data from migrant and English-speaking Australian-born patients with cancer. Patients were recruited through oncology clinics and Australian state cancer registries. Data were collected regarding patient clinical and demographic characteristics and health-care and communication experiences. Data from the clinics and registries were combined for analysis. Significant differences were found between migrant groups in demographic characteristics, communication and health-care experiences, and information and care preferences. Chinese patients cited problems with understanding medical information, the Australian health-care system, and communicating with their health-care team. Conversely, Arabic- and Greek-speaking patients reported higher understanding of the health-care system, and less communication difficulties. Our study findings suggest that migrant groups differ from each other in their health communication expectations and requirements. Lower education and health literacy of some groups may play a role in poorer health outcomes. Public health interventions and assistance provided to migrants should be tailored to the specific needs and characteristics of that language or cultural group. Future research directions are discussed. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Full Text Available BACKGROUND Delirium, a common neuropsychiatric syndrome in intensive care settings is a distressing experience for the patient, caregivers and nursing staff. Research on delirium experience has been scant and unsystematic. We set out to explore the extent of recall of delirium, differential distress it had on patients, caregivers and nursing staff and the extent to which it impacted recognition across the motoric subtypes. MATERIALS AND METHODS A prospective study was carried out on all consecutively admitted patients in the medical ICU of a tertiary care teaching hospital. Patients diagnosed with delirium using Confusion Assessment Method for ICU (CAM-ICU were administered the Richmond Agitation Sedation Scale (RASS for differentiating the motor subtypes (hypoactive, hyperactive, mixed. Distress was assessed using the Delirium Experience Questionnaire (DEQ. RESULTS Of the 88 patients (31.43% who developed delirium, 60.2% recalled their experience. Recall was highest in the hyperactive subtype. 76% of patients, 94.3% of caregivers and 31.8% of nursing staff reported severe levels of distress. Motoric subtypes did not impact on the distress levels experienced by the patients or their caregivers, but influenced it significantly in the nursing staff (highest in hyperactive, least in hypoactive. Identification of delirium by nursing staff (13.4% was significantly influenced by the motor subtypes (highest in hyperactive, least in hypoactive. Linear regression analysis revealed that distress of ICU staff (F=1.36, p=0.018 and not the motoric subtypes (F=1.36, p=0.262 significantly predicted recognition of delirium. CONCLUSIONS Most patients who develop delirium and their caregivers experience high levels of distress. Under-recognition is significantly influenced by the distress it causes the ICU staff than the motor subtype of delirium.

    We assessed the virological response of dual therapy with DRV/r, plus raltegravir, maraviroc or etravirine, in virological failure patients and in virologically suppressed patients collected in the Italian Antiretroviral Resistance Database (ARCA). The primary endpoint was the percentage of patients remaining free of virological failure (confirmed >50 copies/mL or any change in the regimen). Subjects had a resistance test and at least one follow-up visit. Observation was censored at last visit under dual therapy and survival analysis and proportional hazard models were used. Sixty-seven percent of the 221 patients started DRV/r with RAL, 20.4 % with ETV, and 12.2 % with MAR; 31.2 % virological failures were observed. At survival analysis, the overall proportion of failure was 29.2 % at 1 year and 33.8 % at 2 years. The proportion of failure was lower in patients starting with undetectable vs. detectable viral load (13.3 and 25.2 % vs. 37.4 and 38.8 % at 1 and 2 years, respectively, p = 0.001 for both analyses) and in patients treated with DRV 600 BID vs. 800 QD (HR: 0.56, 95 % CI: 0.31-0.99, p HIV-DB HR: 0.53, 95 % CI: 0.32-0.88, p = 0.014; Rega 0.60, 0.40-0.88, p HIV-RNA (3.02, 1.70-5.72, p < 0.001). Among experienced patients, the best candidates for dual-therapy regimens including DRV/r are those with undetectable viral load and higher GSS.

    Can human oocyte calcium analysis predict fertilization success after assisted oocyte activation (AOA) in patients experiencing fertilization failure after ICSI? ICSI-AOA restores the fertilization rate only in patients displaying abnormal Ca2+ oscillations during human oocyte activation. Patients capable of activating mouse oocytes and who showed abnormal Ca2+ profiles after mouse oocyte Ca2+ analysis (M-OCA), have variable responses to ICSI-AOA. It remains unsettled whether human oocyte Ca2+ analysis (H-OCA) would yield an improved accuracy to predict fertilization success after ICSI-AOA. Sperm activation potential was first evaluated by MOAT. Subsequently, Ca2+ oscillatory patterns were determined with sperm from patients showing moderate to normal activation potential based on the capacity of human sperm to generate Ca2+ responses upon microinjection in mouse and human oocytes. Altogether, this study includes a total of 255 mouse and 122 human oocytes. M-OCA was performed with 16 different sperm samples before undergoing ICSI-AOA treatment. H-OCA was performed for 11 patients who finally underwent ICSI-AOA treatment. The diagnostic accuracy to predict fertilization success was calculated based on the response to ICSI-AOA. Patients experiencing low or total failed fertilization after conventional ICSI were included in the study. All participants showed moderate to high rates of activation after MOAT. Metaphase II (MII) oocytes from B6D2F1 mice were used for M-OCA. Control fertile sperm samples were used to obtain a reference Ca2+ oscillation profile elicited in human oocytes. Donated human oocytes, non-suitable for IVF treatments, were collected and vitrified at MII stage for further analysis by H-OCA. M-OCA and H-OCA predicted the response to ICSI-AOA in 8 out of 11 (73%) patients. Compared to M-OCA, H-OCA detected the presence of sperm activation deficiencies with greater sensitivity (75 vs 100%, respectively). ICSI-AOA never showed benefit to overcome

    We examined whether the presence and severity of preoperative hydronephrosis have prognostic significance in patients who underwent radical cystectomy for transitional cell carcinoma of the bladder. The medical records of 457 patients who underwent radical cystectomy for bladder cancer between 1986 and 2005 were retrospectively reviewed. Following the Society for Fetal Urology grading system, patients were divided into low-, and high-grade hydronephrosis groups. Clinicopathologic factors associated with preoperative hydronephrosis and survival were evaluated. Of a total of 406 patients, unilateral hydronephrosis was found in 74 (18.2%), bilateral hydronephrosis in 11 (2.7%), and no hydronephoris in 321 (79.1%). Low-grade hydronephrosis was found in 57 (12.2%) patients and high-grade hydronephrosis in 28 (6%). Preoperative hydronephrosis was related to higher pT stage and lymph node invasion. In univariate analysis, the presence of hydronephrosis, hydronephrosis grade, age, pT and pN stage, tumor grade, surgical margin, number of retrieved nodes, carcinoma in situ, and lymphovascular invasion were significant prognostic factors for cancer-specific survival. In multivariate analysis, bilateral hydronephrosis and high-grade hydronephrosis remained significant predictors for decreased survival. The presence of preoperative hydronephrosis, and high-grade hydronephrosis are significant prognostic factors in patients with bladder cancer after radical cystectomy. PMID:20191034

    Increasingly, patients are expected to influence decisions previously reserved for regulatory agencies, pharmaceutical companies, and healthcare professionals. Individual patients have previously represented their patient population when rare, serious adverse events (AEs) were weighed as part of a benefit-risk assessment. However, the degree of heterogeneity of the patient population is critical for how accurately they can be represented by individuals. This study aims to explore patients' risk perception of rare, serious adverse effects of medicines with regard to blood glucose-lowering antidiabetics used by the individual patient. Semi-structured interviews were conducted with 18 patients with diabetes with self-perceived serious, but not necessarily rare, AEs (e.g. stroke or valve or bypass surgery). The interviews explored the patients' history of disease, perceptions of the terms rare and serious, and overall levels of risk aversion. A thematic analysis of the interviews, including a consensus discussion, was carried out. Interestingly, respondents rarely made a clear distinction between medicines-induced AEs and complications related to disease progression. Concerns regarding AEs were apparently diverse but were systematically related to the personal experiences of the respondents. Respondents routinely ignored information about possible rare, serious AEs, unless it could be related to personal experience. In the absence of experience, concerns were focused on common and less serious AEs, thus disregarding rare and more serious events. The study suggests that experience of AEs, related to either medicines or disease, constitutes an important factor of patient risk perception. We therefore propose that serious adverse experiences should be added to the traditional panel of socioeconomic factors that are accounted for when patients are invited to give input on regulatory decisions.

    Studies available have described several specific issues affecting healthcare accessibility by deaf people, but to date, no research has reported the experience of deaf patients with in-hospital communication. The aim of the study was to explore the communication experience of deaf patients with regard to their in-hospital stay. A purposeful sample of participants was selected. The data collection process was based on a focus group. The focus groups were conducted in Italian sign language and videorecorded; subsequently, the entire conversation was faithfully transcribed. A qualitative content analysis of the transcription was performed and the findings are reported using the Consolidated Criteria for Reporting Qualitative Research approach. Four themes have emerged: (a) experiencing a common vulnerability: the need for reciprocal understanding and sensitivity, (b) being outside the comfort zone: feeling discriminated against once again, (c) perceiving a lack of consonance between care and needs and (d) developing a sense of progressively disempowerment. The experience of deaf individuals during their in-hospital stay may be critical: they are exposed to protracted communication and interaction with healthcare providers and an environment that is not prepared and designed for these vulnerable patients. Two levels of strategies should be identified, implemented and developed to increase the quality of communication with deaf people during hospitalisation, both at the hospital/health system level and at the healthcare professional/clinical level. © 2016 Nordic College of Caring Science.

    To assess if counselling by an occupational physician (OP) addressing experienced workplace barriers and physical activity integrated as a part of low-back pain (LBP) outpatient treatment influences pain, function and sick leave. Randomised controlled trial in the secondary healthcare sector with 3 months' follow-up. The participants were LBP patients who, independently of sick-leave status, expressed concerns about the ability to maintain their current job. Patients referred for surgery were excluded. The intervention consisted of two counselling sessions conducted by an OP addressing both workplace barriers and leisure-time physical activity. A workplace visit was performed if required. Pain, function and duration of sick leave due to LBP were primary outcomes. A reduction in bodily pain and improvement in physical function both measured by the 36-item short-form health survey questionnaire in favour of the intervention group was found. The change in pain score was found to be clinically relevant. The risk of sick leave for at least 8 weeks due to LBP was significantly reduced in the intervention group. Two secondary outcomes, Fear Avoidance Beliefs about physical activity and maximum oxygen uptake, supported compliance and adherence to the part of the intervention focusing on enhanced physical activity. Two short counselling sessions by an OP combining advice on meeting workplace barriers and enhancing physical activity had a substantial effect on important prognostic factors for LBP patients with moderate to severe symptoms diagnosed in outpatient rheumatological clinics.

    Background. A systematic comparison of magnetic resonance imaging (MRI) options for glioma diagnosis is lacking. Purpose. To investigate multiple MR-derived image features with respect to diagnostic accuracy in tumor grading and survival prediction in glioma patients. Material and Methods. T1 pre- and post-contrast, T2 and dynamic susceptibility contrast scans of 74 glioma patients with histologically confirmed grade were acquired. For each patient, a set of statistical features was obtained from the parametric maps derived from the original images, in a region-of-interest encompassing the tumor volume. A forward stepwise selection procedure was used to find the best combinations of features for grade prediction with a cross-validated logistic model and survival time prediction with a cox proportional-hazards regression. Results. Presence/absence of enhancement paired with kurtosis of the FM (first moment of the first-pass curve) was the feature combination that best predicted tumor grade (grade II vs. grade III-IV; median AUC 0.96), with the main contribution being due to the first of the features. A lower predictive value (median AUC = 0.82) was obtained when grade IV tumors were excluded. Presence/absence of enhancement alone was the best predictor for survival time, and the regression was significant (P < 0.0001). Conclusion. Presence/absence of enhancement, reflecting transendothelial leakage, was the feature with highest predictive value for grade and survival time in glioma patients

    Background. Colorectal cancer is becoming a chronic condition. This has significant implications for the delivery of health care and implies the involvement of a range of health care professionals (HCPs) from different settings to ensure the needed quality and continuity of care. Objectives. To explore the challenges that patients and HCPs experience in the course of colorectal cancer care and the perceived consequences caused by these challenges. Methods. Ten semi-structured focus groups were conducted including patients receiving treatment for colorectal cancer, representatives of patient support groups, physicians and other non-physician HCPs from different health care settings. Participants were asked to share their experiences regarding colorectal cancer care. All data were audio- and videotaped, transcribed verbatim and thematically analysed using qualitative content analysis. Results. Patients and HCPs (total N = 47) experienced collaboration and communication as well as exchange of information between HCPs as challenging. Particularly communication and information exchange with GPs appeared to be lacking. The difficulties identified restricted a well-working coordination of care and seemed to cause inappropriate health care. Conclusion. Colorectal cancer care seems to require an effective, well-working collaboration and communication between the different HCPs involved ensuring the best possible care to suit patients’ individual needs. However, the perceived challenges and consequences of our participants seem to restrict the delivery of the needed quality of care. Therefore, it seems crucial (i) to include all HCPs involved, especially the GP, (ii) to support an efficient and standardized exchange of health-related information and (iii) to focus on the patients’ entire pathway of care.

    To identify, appraise and synthesize the best available evidence exploring nursing students' experiences of professional patient care encounters in a hospital unit. The Joanna Briggs Institute (JBI) guidelines were followed and a meta-synthesis was conducted. Qualitative research articles were considered for inclusion in the review, and JBI's meta-aggregative approach to synthesizing qualitative evidence was followed. An extensive search for relevant literature was undertaken in scientific databases. Data were extracted from the included research articles, and qualitative research findings were pooled using the Qualitative Assessment and Review Instrument. This involved categorization of findings on the basis of similarity of meaning and aggregation of these categories to produce a comprehensive set of synthesized findings. A total of five research articles met the inclusion criteria and were included in the review. The review process resulted in 46 subcategories that were aggregated into 13 categories. The categories generated four synthesized findings: personal existence; personal learning and development; being a professional fellow human; and clinical learning environment. We meta-synthesized that: Nursing students experienced personal inadequacy, vulnerability and a transformation during their patient care encounter. Copyright © 2018 Elsevier Ltd.

    Yemisi Okikiade Oyegbile

    Full Text Available Background: Family caregivers in many African countries bear the burden of caregiving alone, with the paucity of research, especially for caregivers of End-Stage Renal Disease patients, having concealed their needs. Aim: To explore the caregiver burden of family caregivers of End-Stage Renal Disease (ESRD patients in South-West Nigeria. Design: Following a complementary mixed method data collection strategy, the quantitative data was collected using the Zarit Burden Interview questionnaire to measure the burden of caregiving. Qualitative data was thereafter obtained through in-depth, individual interviews and was analysed using content analysis. Settings: The three research settings consisted of two state hospitals and one private hospital that provide renal care in South-West Nigeria. Result: The mean burden of caregiving for the sample was 50.18 thus indicating that family caregivers experienced moderate to severe burden, which is high compared to the other studies. The participants’ experiences of caregiving revealed the following categories: total dependence, acceptance of caregiving role, competing responsibilities, financial sacrifice and “not making mistakes”. Conclusion: Understanding the extent of caregiver burden, what constitutes burden to family caregivers in low/middle-income countries, and the difficulties associated with caregiving for care-recipients with ESRD, allows appropriate strategies and interventions to be developed.

    The aims of this study were to assess the potential of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET) for tumor grading in chondrosarcoma patients and to evaluate the role of standardized uptake value (SUV) as a parameter for prediction of patient outcome. FDG PET imaging was performed in 31 patients with chondrosarcoma prior to therapy. SUV was calculated for each tumor and correlated to tumor grade and size, and to patient outcome in terms of local relapse or metastatic disease with a mean follow-up period of 48 months. Chondrosarcomas were detectable in all patients. Tumor SUV was 3.38{+-}1.61 for grade I (n=15), 5.44{+-}3.06 for grade II (n=13), and 7.10{+-}2.61 for grade III (n=3). Significant differences were found between patients with and without disease progression: SUV was 6.42{+-}2.70 (n=10) in patients developing recurrent or metastatic disease compared with 3.74{+-}2.22 in patients without relapse (P=0.015). Using a cut-off of 4 for SUV, sensitivity, specificity, and positive and negative predictive values for a relapse were 90%, 76%, 64%, and 94%, respectively. Combining tumor grade and SUV, these parameters improved to 90%, 95%, 90%, and 95%, respectively. Pretherapeutic tumor SUV obtained by FDG PET imaging was a useful parameter for tumor grading and prediction of outcome in chondrosarcoma patients. The combination of SUV and histopathologic tumor grade further improved prediction of outcome substantially, allowing identification of patients at high risk for local relapse or metastatic disease.

    The most widely used grading system for blunt splenic injury is the American Association for the Surgery of Trauma (AAST) organ injury scale. In 2007 a new grading system was developed. This 'Baltimore CT grading system' is superior to the AAST classification system in predicting the need for angiography and embolization or surgery. The objective of this study was to assess inter- and intraobserver reliability between radiologists in classifying splenic injury according to both grading systems. CT scans of 83 patients with blunt splenic injury admitted between 1998 and 2008 to an academic Level 1 trauma centre were retrospectively reviewed. Inter and intrarater reliability were expressed in Cohen's or weighted Kappa values. Overall weighted interobserver Kappa coefficients for the AAST and 'Baltimore CT grading system' were respectively substantial (kappa=0.80) and almost perfect (kappa=0.85). Average weighted intraobserver Kappa's values were in the 'almost perfect' range (AAST: kappa=0.91, 'Baltimore CT grading system': kappa=0.81). The present study shows that overall the inter- and intraobserver reliability for grading splenic injury according to the AAST grading system and 'Baltimore CT grading system' are equally high. Because of the integration of vascular injury, the 'Baltimore CT grading system' supports clinical decision making. We therefore recommend use of this system in the classification of splenic injury.

    We recently reported a grading system for surgical complications. This system proved to have a high sensitivity for recording minor but meaningful complications prolonging hospital stay in patients after colorectal surgery. We aimed to prospectively validate the complication grading system in a general surgery department over 1 year. All surgical procedures and related complications were prospectively recorded between January 1st and December 31st, 2009. Surgical complications were graded on a severity scale of 1-5. The system classifies short-term outcome by grade emphasizing intensity of therapy required for treatment of the defined complication. During the study period, 2114 patients underwent surgery. Elective and oncological surgeries were performed in 1606 (76%) and 465 (22%) patients, respectively. There were 422 surgical complications in 304 (14%) patients (Grade 1/2: 203 [67%]; Grade 3/4: 90 [29%]; Grade 5: 11 [4%]). Median length of stay correlated significantly with complication severity: 2.3 d for no complication, 6.2 and 11.8 d for Grades 1/2 and 3/4, respectively (P 2 (OR 2.07, P Grade (OR 1.85, P = 0.001), oncological (OR 2.82, P 120 min (OR 2.08, P grading surgical complications permits standardized reporting of surgical morbidity according to the severity of impact. Prospective validation of this system supports its use in a general surgery setting as a tool for surgical outcome assessment and quality assurance. Copyright © 2014 Elsevier Inc.

    Full Text Available OBJECTIVES: To investigate the expression and prognostic value of bone sialoprotein (BSP in glioma patients. METHODS: We determined the expression of BSP using real-time RT-PCR and immunohistochemistry in tissue microarrays containing 15 normal brain and 270 glioma samples. Cumulative survival was calculated by the Kaplan-Meier method and analyzed by the log-rank test. Univariate and multivariate analyses were performed by the stepwise forward Cox regression model. RESULTS: Both BSP mRNA and protein levels were significantly elevated in high-grade glioma tissues compared with those of normal brain and low-grade glioma tissues, and BSP expression positively correlated with tumor grade (P<0.001. Univariate and multivariate analysis showed high BSP expression was an independent prognostic factor for a shorter progression-free survival (PFS and overall survival (OS in both grade III and grade IV glioma patients [hazard ratio (HR = 2.549 and 3.154 for grade III glioma, and HR = 1.637 and 1.574 for grade IV glioma, respectively]. Patients with low BSP expression had a significantly longer median OS and PFS than those with high BSP expression. Small extent of resection and lineage of astrocyte served as independent risk factors of both shorter PFS and OS in grade III glioma patients; GBM patients without O(6-methylguanine (O(6-meG DNA methyltransferase (MGMT methylation and Karnofsky performance score (KPS less than 70 points were related to poor prognosis. Lack of radiotherapy related to shorter OS but not affect PFS in both grade III and grade IV glioma patients. CONCLUSION: High BSP expression occurs in a significant subset of high-grade glioma patients and predicts a poorer outcome. The study identifies a potentially useful molecular marker for the categorization and targeted therapy of gliomas.

    Orthodontics in China has developed rapidly, but there is no standard index of treatment outcomes. We assessed the validity of the American Board of Orthodontics Objective Grading System (ABO-OGS) for the classification of treatment outcomes in Chinese patients. We randomly selected 108 patients who completed treatment between July 2005 and September 2008 in 6 orthodontic treatment centers across China. Sixty-nine experienced Chinese orthodontists made subjective assessments of the end-of-treatment casts for each patient. Three examiners then used the ABO-OGS to measure the casts. Pearson correlation analysis and receiver operating characteristic curve analysis were conducted to evaluate the correspondence between the ABO-OGS cast measurements and the orthodontists' subjective assessments. The average subjective grading scores were highly correlated with the ABO-OGS scores (r = 0.7042). Four of the 7 study cast components of the ABO-OGS score-occlusal relationship, overjet, interproximal contact, and alignment-were statistically significantly correlated with the judges' subjective assessments. Together, these 4 accounted for 58% of the variability in the average subjective grading scores. The ABO-OGS cutoff score for cases that the judges deemed satisfactory was 16 points; the corresponding cutoff score for cases that the judges considered acceptable was 21 points. The ABO-OGS is a valid index for the assessment of treatment outcomes in Chinese patients. By comparing the objective scores on this modification of the ABO-OGS with the mean subjective assessment of a panel of highly qualified Chinese orthodontists, a cutoff point for satisfactory treatment outcome was defined as 16 points or fewer, with scores of 16 to 21 points denoting less than satisfactory but still acceptable treatment. Cases that scored greater than 21 points were considered unacceptable. Copyright © 2013 American Association of Orthodontists. Published by Mosby, Inc. All rights reserved.

    Full Text Available The prostatic adenocarcinoma is one of the most frequent malignant tumors of men over 50 years of age. It is distinguished by agressive clinical course and heterogeneous multifocal hystomorphologic changes. PSA is the most reliable serum marker in diagnostics and observation of prostatic carcinoma and gleason's system of tumor-diferentiation grading is generally accepted way of determining the hystologic grade. Gleason's system is correlated with serum levels of PSA and with biological behaviour of the tumor. We presented 40 patients with verified ACP in whom the level of serum PSA, gleason's grade and score were compared. Highly significant correlation was found between serum level of PSA and the differentation grade of the tumor - Gleason's grade and score. Combination of PSA parameters and Gleason's score enables correct estimation of tumor's behaviour and correct therapeutic protocole.

    The addition of PCV (procarbazine, lomustine, and vincristine) chemotherapy to radiotherapy (RT) for patients with WHO grade 2 glioma improves progression-free survival (PFS). The effect of therapy intensification on cognitive function (CF) remains a concern in this population with substantial long-term survival. A total of 251 patients with WHO grade 2 glioma age ≥ 40 years with any extent of resection or age point. Both study arms experienced a significant gain in average MMSE score longitudinally over time, with no difference between arms. The MMSE is a relatively insensitive tool, and subtle changes in CF may have been missed. However, the addition of PCV to RT did not result in significantly higher rates of MMSE score decline than RT alone through 5 years of follow-up. Patients in both randomly assigned arms experienced a statistically significant average MMSE score increase over time, with no difference between arms. The addition of PCV chemotherapy to RT improves PFS without excessive CF detriment over RT alone for patients with low-grade glioma.

    Full Text Available Breast cancer is one of the most common origins of metastatic lesions in the central nervous system. Many patients with a breast cancer and concurrent brain tumor(s were diagnosed to have a metastatic lesion or lesions in the brain, based exclusively on their image findings without further pathologic verification, and received radiotherapy alone thereafter. It is, however, possible that a different pathology such as primary brain malignancy, which actually warrants a specific treatment modality, may occur in such patients with an already known malignancy. We, herein, reported a 61-year-old female patient who suffered from an anaplastic oligodendroglioma 1 year after her diagnosis of breast cancer. Demographic data, characteristic imaging findings, treatment, and outcome of the patient were discussed.

    Owing to the variability of histopathological features and biological behaviour in gastric carcinoma, a great number of categorisation methods such as classical histopathologic grading, Lauren classification, the TNM staging system and the newly presented Goseki grading method are used by pathologists and other scientists. In our study, we aimed to investigate whether Goseki grade and tumour location have an effects on survival of gastric cancer cases. Eighty-four patients with gastric adenocarcinoma were covered in the investigation. The importance of Goseki grading system and tumour location were analysed in addition to the TNM staging and other conventional prognostic parameters. The median survival time in our patients was 35 months (minimum: 5, maximum: 116). According to our findings, there was no relation between survival and tumour size (p=0.192) or classical histological type (p=0.270). In contrast, the Goseki grade and tumour location significantly correlated with survival (p=0.007 and p<0.001, respectively). Additionally, tumours of the intestinal type had a longer median survival time (60.0 months) than diffuse tumours (24.0 months). In addition to the TNM staging system, tumour location and the Goseki grading system may be used as significant prognostic parameters in patients with gastric cancer.

    Fibromyalgia is a chronic musculoskeletal pain syndrome characterized by a broad spectrum of manifestations. Patients with fibromyalgia frequently suffer from manifestations similar to those experienced by patients with gluten-related disorders raising the possibility that some patients with fibromyalgia could suffer from underlying gluten sensitivity. This study aims to assess whether avoiding gluten among patients with fibromyalgia and gluten sensitivity is beneficial. Adult patients with fibromyalgia presenting gluten sensitivity symptoms are randomly allocated to receive gluten-free diet or hypocaloric diet for 24 weeks. The primary outcome measure is the mean change in the number of experienced gluten sensitivity symptoms. Secondary outcome measures include the mean changes in the body mass index, Revised Fibromyalgia Impact Questionnaire, Pittsburgh Sleep Quality Index, Brief Pain Inventory, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Short-Form Health Survey and Patient Global Impression Scale of Severity. Other secondary outcome measures include the frequency of potential adverse events and the proportion of responders according to the Patient Global Impression Scale of Improvement. Previous studies assessing dietary interventions in fibromyalgia primarily evaluated their effects on the severity and impact of fibromyalgia symptoms and pain. The current study is the first to evaluate the effects of gluten-free diet on the gluten sensitivity symptoms experienced by patients with fibromyalgia. The results of this study will contribute to a better understanding of the potential role of gluten sensitivity in fibromyalgia. Copyright © 2014 Elsevier Inc. All rights reserved.

    To determine the severity of thrombocytopenia in different grades of esophageal varices. Study Design: Cross-sectional analytical study. Place and Duration of Study: Jinnah Postgraduate Medical Centre, Karachi, Medical Unit-III, Ward-7 from January to December 2008. Methodology: Subjects were eligible if they had a diagnosis of cirrhosis. Patient with advanced cirrhosis (Child-Pugh class C), human immunodeficiency virus (HIV) infection, hepatocellular carcinoma, portal vein thrombosis, parenteral drug addiction, current alcohol abuse and previous or current treatment with b-blockers, diuretics and other vasoactive drugs were excluded from the study. All patients under went upper gastrointestinal endoscopy after consent. On the basis of platelet count patients were divided into four groups. Group I with platelets greater or equal to 20000/mm/sup 3/, Group II with values of 21000- 50000/mm/sup 3/, Group III with count of 51000-99000/mm/sup 3/ and Group IV with count of 100000-150000/mm/sup 3/. Correlation of severity of thrombocytopenia with the grading of esophageal varices was assessed using Spearman's correlation with r-values of 0.01 considered significant. Results: One hundred and two patients with thrombocytopenia and esophageal varices were included in the study. There were 62 (60.8%) males and 40 (39.2%) females. The mean age of onset of the disease in these patients was 49.49 +- 14.3 years with range of 11-85 years. Major causes of cirrhosis were hepatitis C (n=79, 77.5%), hepatitis B (n=12, 11.8%), mixed hepatitis B and C infection (n=8, 7.8%) and Wilson's disease (n=3,2.9%). Seven patients had esophageal grade I, 24 had grade II, 35 had grade III, and 36 had grade IV. Gastric varices were detected in 2 patients. Portal hypertensive gastropathy were detected in 87 patients. There was an inverse correlation of platelet count with grading of esophageal varices (r=-0.321, p < 0.001). Conclusion: The severity of thrombocytopenia increased as the grading of

    Full Text Available Purpose. Whistleblowing is the reporting of illegal, immoral, or illegitimate practices to persons or organizations that may affect the action. The current study compares experienced nurses to nursing students regarding their willingness to blow the whistle to protect a patient’s interests. Methods. 165 participants were divided into two groups: 82 undergraduate nursing students and 83 experienced nurses. Participants responded to two vignettes that described a colleague’s and a manager’s misconduct at work. Results. The nursing students perceived the severity of the misconduct significantly lower compared to the experienced nurses. The nursing students also ranked the internal and external whistleblowing indices higher than the nurses, but the differences did not reach statistical significance. For each of the examined internal and external indices, professional experience was found to be significant in multivariate regression analyses. Conclusions. Even though nursing students perceived the severity of the misconduct significantly lower than the experienced nurses, the students demonstrated a greater readiness to blow the whistle, both internally and externally. Recommendations for handling comparable situations are offered.

    The identification and grading of adverse events (AEs) during the conduct of clinical trials is a labor-intensive and error-prone process. This paper describes and evaluates a software tool developed by City of Hope to automate complex algorithms to assess laboratory results and identify and grade AEs. We compared AEs identified by the automated system with those previously assessed manually, to evaluate missed/misgraded AEs. We also conducted a prospective paired time assessment of automated versus manual AE assessment. We found a substantial improvement in accuracy/completeness with the automated grading tool, which identified an additional 17% of severe grade 3-4 AEs that had been missed/misgraded manually. The automated system also provided an average time saving of 5.5 min per treatment course. With 400 ongoing treatment trials at City of Hope and an average of 1800 laboratory results requiring assessment per study, the implications of these findings for patient safety are enormous.

    In South Korea, about 20 types of antiretroviral drugs are used in the treatment of patients with human immunodeficiency virus/acquired immune deficiency syndrome. Since 2010, raltegravir, etravirine, and darunavir have been spotlighted as new drugs for highly active antiretroviral therapy (HAART)-experienced adults with resistant HIV-1 in South Korea. In this study, we investigated potential susceptibility of pseudoviruses derived from treatment-experienced Korean patients to etravirine vs efavirenz and to darunavir vs amprenavir and indinavir using a modified single-round assay. Pseudoviruses derived from nine treatment-experienced patients infected with HIV-1 were investigated by comparison with the wild-type strain pNL4-3. The 50% inhibitory concentration (IC50) values were calculated and drug susceptibility was compared. The intensity of genotypic drug resistance was classified based on the 'SIR' interpretation of the Stanford data base. Drug susceptibility was generally higher for etravirine and darunavir compared with efavirenz, amprenavir, and indinavir in pseudoviruses derived from treatment-experienced patients. Pseudoviruses derived from patients KRB4025 and KRB8014, who exhibited long-term use of protease inhibitors, showed an outside of tested drug concentration, especially for amprenavir and indinavir. However, they exhibited a lower fold-change in resistance to darunavir. Etravirine and darunavir have been used in HAART since 2010 in South Korea. Therefore, these antiretroviral drugs together with other newly introduced antiretroviral drugs are interesting for the optimal treatment of patients with treatment failure. This study may help to find a more effective HAART in the case of HIV-1 infected patients that have difficulty being treated.

    The medical charts of 801 consecutive patients transferred to our critical care center over a 14-year interval (1994-2007) in poor neurological condition (World Federation of Neurological Surgeons; WFNS grade IV or V) after subarachnoid hemorrhage (SAH) were retrospectively analyzed. All patients were treated following a strict protocol. After initial neurological evaluation, patients were sedated, paralyzed, and underwent strict blood pressure control. For patients with WFNS grade IV and selected patients with grade V, aggressive ultra-early repair (mainly clipping for anterior circulation aneurysm, coiling for posterior circulation aneurysm) was initiated. In grade V patients with poor brainstem function or destruction of vital brain areas on CT, only comfort measures were offered. Compared to the former period (1994-2000), coiling was more frequently indicated in elderly patients and bypass surgery was more often applied in complex aneurysm cases in the latter period (2001-2007). Compared to the former period, the number of aggressively treated patients significantly increased (37.6% versus 28.8%) in the latter period. Outcome assessments performed at 3 months revealed a significant increase of favorable outcomes (Glasgow Outcome Scale; good recovery (GR) or moderately disabled (MD)) and a decreased mortality rate in those patients (34% versus 28%, and 43% versus 47%; respectively). The ratio of favorable outcome and morbidity in all admitted patients were also improved (12% versus 8%, and 79% versus 85%; respectively). Outcome was largely determined by the initial hemorrhage and subsequent development of intractable intracranial hypertension or cerebral infraction. Age was also found to be significantly correlated with outcome. There was no significant difference in outcomes by treatment modality (clip or coil). In the latter period, aneurismal location was not the predictor, but delayed ischemic neurological deficit (DIND) remained an important factor. In

    The prognostic value of the Fuhrman nuclear grading system has been questioned for chromophobe renal cell carcinoma (chRCC) because this subtype frequently displays nuclear and nucleolar pleomorphism. The present study reevaluates this grading system in a series of patients with nonsarcomatoid chRCC. We identified 176 patients (3.6%) with nonsarcomatoid chRCC in a total of 4897 patients who underwent surgery for renal cell carcinoma at 5 centers in Germany between 1990 and 2010. The mean follow-up was 51.1 months. The 3 groups (G1 versus G2 versus G3/4) were comparable in terms of age, sex, tumor diameter, and lymph node metastasis. They only differed significantly in tumor stage (P = .01) and the incidence of synchronous visceral metastasis (P = .04). The 5-year cancer-specific survival rates were 84.4% for G1 (n = 32), 84.3% for G2 (n = 108), and 74.1% for G3/4 tumors (n = 33) (P = .58). Accordingly, multivariate analysis including age, sex, tumor stage, and metastatic disease did not identify Fuhrman grading as an independent predictor of cancer-specific survival in patients with chRCC (P = .4). We were able to demonstrate in a large multicenter cohort that the Fuhrman grading system does not qualify as a prognostic tool in patients with chRCC. Copyright © 2014 Elsevier Inc.

    Endoscopic subureteral injection of dextranomer/hyaluronic acid has become an established alternative to long-term antibiotic prophylaxis or surgical treatment for vesicoureteral reflux. We evaluated the effectiveness of endoscopic injection of dextranomer/hyaluronic acid in intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems. A total of 123 children underwent endoscopic correction of intermediate or high grade vesicoureteral reflux using injection of dextranomer/hyaluronic acid into complete duplex systems between 2001 and 2010. Vesicoureteral reflux was diagnosed by voiding cystourethrogram, and dimercapto-succinic acid scan was performed to evaluate the presence of renal scarring. Followup ultrasound and voiding cystourethrogram were performed 3 months after the outpatient procedure and renal ultrasound thereafter every 2 years. Mean followup was 6.7 years. Complete duplex systems were unilateral in 110 patients and bilateral in 13. Reflux severity in the 136 refluxing units was grade II in 1 (0.7%), III in 52 (38.2%), IV in 61 (44.9%) and V in 22 (16.2%). Dimercapto-succinic acid scan revealed renal functional abnormalities in 63 children (51.2%). Vesicoureteral reflux resolved after the first endoscopic injection of dextranomer/hyaluronic acid in 93 ureters (68.4%), after a second injection in 35 (25.7%) and after a third injection in 8 (5.9%). Febrile urinary tract infection developed in 5 patients (4.1%) during followup. No patient required ureteral reimplantation or experienced significant complications. Our results confirm the safety and efficacy of endoscopic injection of dextranomer/hyaluronic acid in eradicating intermediate and high grade vesicoureteral reflux in patients with complete duplex systems. We recommend this minimally invasive, 15-minute outpatient procedure as a viable option for treating intermediate and high grade vesicoureteral reflux in patients with complete duplex collecting systems

    The authors studied the histological alterations and the expression of matrix metalloproteinase (MMP)-1 and MMP-3 in disc specimens of patients who had undergone operations for lumbar disc herniation. Forty-three lumbar disc specimens were evaluated histopathologically for degenerative changes and immunohistochemical expression of MMP-1 and MMP-3. The observed degenerative changes provided a degenerative score that was applied in each patient. Sections of disc immunostained for MMP-1 and MMP-3 were evaluated semiquantitatively. Patients were categorized in 3 age groups: 60 years of age. The expression of MMP-1 and MMP-3 were correlated to patient's age, degenerative score, and grade of lumbar disc herniation. There was no statistically significant difference in the degenerative score between the age groups. Degenerative changes were more pronounced in greater grades of herniation (p correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. For the group of patients 30-60 years of age, there was no significant difference between MMP-1 expression and degenerative score, but the correlation between MMP-1 expression and grade of herniation was significant. There was a significant correlation between MMP-3 expression and both degenerative score and herniation grade. Regarding the patients > 60 years of age, there was a significant correlation between MMP-1 and MMP-3 expression and both degenerative score and herniation grade. There was a significantly lower expression of both MMP-1 and MMP-3 in the group correlation was found in MMP-1 and MMP-3 expression between the groups of patients who were 30-60 and > 60 years of age. Interestingly, in age groups > 30 years, there were no statistically significant differences between the expression of MMP-1 and MMP-3, whereas in patients correlated to the age of the patients and the grade of herniation. An important finding in this study is the differential expression of MMP-1 and MMP-3

    To associate the presence of language deficits with varying scores of the Fisher grading scale in patients with subarachnoid hemorrhage in the period preceding the treatment of aneurysm in the anterior circulation, as well as to compare the scores of this scale, identifying the grades more associated with the decline of language. Database analysis of 185 preoperative evaluations of language, through the Montreal Toulouse Protocol Alpha version and verbal fluency through CERAD battery, of patients from "Hospital da Restauração" with aneurysmal subarachnoid hemorrhage, divided according to the Fisher grading scale (Fisher I, II, III, or IV) and compared with a control group of individuals considered normal. The various scores of the Fisher grading scale have different levels of language deficits, more pronounced as the amount of blood increases. Fisher III and IV scores are most associated with the decline of language. Our study made it possible to obtain information not yet available in the literature, by correlating the various scores of the Fisher grading scale with language yet in the period preceding treatment.

    Early and accurate identification of tumor progression in patients with low-grade gliomas is challenging. We aimed to assess the role of quantitative ADC analysis in the sequential follow-up of patients with low-grade gliomas as a potential imaging marker of tumor stability or progression. In this retrospective study, patients with a diagnosis of low-grade glioma with at least 12 months of imaging follow-up were retrospectively reviewed. Two neuroradiologists independently reviewed sequential MR imaging in each patient to determine tumor progression using the Response Assessment in Neuro-Oncology criteria. Normalized mean ADC (ADC mean ) and 10th percentile ADC (ADC 10 ) values from FLAIR hyperintense tumor volume were calculated for each MR image and compared between patients with stable disease versus tumor progression using univariate analysis. The interval change of ADC values between sequential scans was used to differentiate stable disease from progression using the Fisher exact test. Twenty-eight of 69 patients who were evaluated met our inclusion criteria. Fifteen patients were classified as stable versus 13 patients as having progression based on consensus reads of MRIs and the Response Assessment in Neuro-Oncology criteria. The interval change of ADC values showed greater concordance with ultimate lesion disposition than quantitative ADC values at a single time point. The interval change in ADC 10 matched the expected pattern in 12/13 patients with tumor progression (overall diagnostic accuracy of 86%, P average, the ADC 10 interval change predicted progression 8 months before conventional MR imaging. The interval change of ADC 10 values can be used to identify progression versus stability of low-grade gliomas with a diagnostic accuracy of 86% and before apparent radiologic progression on conventional MR imaging. © 2018 by American Journal of Neuroradiology.

    To evaluate and predict factors influencing prognosis and/or clinical outcome at 6 months in patients with spontaneous subarachnoid haemorrhage, World Federation of Neurosurgical Societies (WFNS) grades iv and v. This was a retrospective study of a consecutive series of 394 patients admitted to our hospital with clinical and radiological diagnosis of spontaneous subarachnoid haemorrhage, from 1 January 1999 to 30 June 2009. We selected 121 patients who met the criteria of being in WFNS grades iv or v before treatment; 3 patients were excluded due to loss of tracking. The outcome variable was assessed 6 months after the event using the Glasgow Outcome Scale. A P value<.05 was considered statistically significant. One hundred and twenty-one patients were included in the statistical analysis. The average age of the patients in the series was 54 years (14-92). Patients who had a mean Glasgow Coma Scale lower than 7 points (P<.0001), those who were grade v (P<.0001) in the pre-treatment WFNS scale and those with pupillary disorder (P=.002) had a worse clinical outcome. Likewise, those with associated intraparenchymal hematoma (P=.020) and those not receiving any treatment (P=.020) were also associated with a poor clinical outcome. These results were statistically significant. Patients admitted with a WFNS grade v and/or presenting pupil disorder and/or intraparenchymal hematoma were associated with worse clinical outcomes.

    We retrospectively generated IMRT plans for 14 NSCLC patients who had experienced grade 2 or 3 esophagitis (CTCAE version 3.0). We generated 11-beam and reduced esophagus dose plan types to compare changes in the volume and length of esophagus receiving doses of 50, 55, 60, 65, and 70 Gy. Changes in planning target volume (PTV) dose coverage were also compared. If necessary, plans were renormalized to restore 95% PTV coverage. The critical organ doses examined were mean lung dose, mean heart dose, and volume of spinal cord receiving 50 Gy. The effect of interfractional motion was determined by applying a three-dimensional rigid shift to the dose grid. For the esophagus plan, the mean reduction in esophagus V50, V55, V60, V65, and V70 Gy was 2.8, 4.1, 5.9, 7.3, and 9.5 cm(3), respectively, compared with the clinical plan. The mean reductions in LE50, LE55, LE60, LE65, and LE70 Gy were 2.0, 3.0, 3.8, 4.0, and 4.6 cm, respectively. The mean heart and lung dose decreased 3.0 Gy and 2.4 Gy, respectively. The mean decreases in 90% and 95% PTV coverage were 1.7 Gy and 2.8 Gy, respectively. The normalized plans' mean reduction of esophagus V50, V55, V60, V65, and V70 Gy were 1.6, 2.0, 2.9, 3.9, and 5.5 cm(3), respectively, compared with the clinical plans. The normalized plans' mean reductions in LE50, LE55, LE60, LE65, and LE70 Gy were 4.9, 5.2, 5.4, 4.9, and 4.8 cm, respectively. The mean reduction in maximum esophagus dose with simulated interfractional motion was 3.0 Gy and 1.4 Gy for the clinical plan type and the esophagus plan type, respectively. In many cases, the esophagus dose can be greatly reduced while maintaining critical structure dose constraints. PTV coverage can be restored by increasing beam output, while still obtaining a dose reduction to the esophagus and maintaining dose constraints.

    Amino acid positron emission tomography (PET) with [18F]-fluoroethyl-L-tyrosine (FET) is well established in the diagnostic work-up of malignant brain tumors. Analysis of FET-PET data using tumor-to-background ratios (TBR) has been shown to be highly valuable for the detection of viable hypermetabolic brain tumor tissue; however, it has not proven equally useful for tumor grading. Recently, textural features in 18-fluorodeoxyglucose-PET have been proposed as a method to quantify the heterogeneity of glucose metabolism in a variety of tumor entities. Herein we evaluate whether textural FET-PET features are of utility for grading and prognostication in patients with high-grade gliomas. One hundred thirteen patients (70 men, 43 women) with histologically proven high-grade gliomas were included in this retrospective study. All patients received static FET-PET scans prior to first-line therapy. TBR (max and mean), volumetric parameters and textural parameters based on gray-level neighborhood difference matrices were derived from static FET-PET images. Receiver operating characteristic (ROC) and discriminant function analyses were used to assess the value for tumor grading. Kaplan-Meier curves and univariate and multivariate Cox regression were employed for analysis of progression-free and overall survival. All FET-PET textural parameters showed the ability to differentiate between World Health Organization (WHO) grade III and IV tumors (p < 0.001; AUC 0.775). Further improvement in discriminatory power was possible through a combination of texture and metabolic tumor volume, classifying 85 % of tumors correctly (AUC 0.830). TBR and volumetric parameters alone were correlated with tumor grade, but showed lower AUC values (0.644 and 0.710, respectively). Furthermore, a correlation of FET-PET texture but not TBR was shown with patient PFS and OS, proving significant in multivariate analysis as well. Volumetric parameters were predictive for OS, but this correlation did not

    This study aims to develop a self-reflection program for nurses who have experienced the death of pediatric patients in the intensive care unit and to evaluate its effectiveness. The self-reflection program was developed by means of the following four steps: establishment of the goal through investigation of an initial request, drawing up the program, preliminary research, and implementation and improvement of the program. The study employed a methodological triangulation to evaluate the effectiveness of the program. Participants were 38 nurses who had experienced the death of pediatric patients (experimental group=15, control group=23); they were recruited using convenience sampling. The self-reflection program was provided over 6 weeks (6 sessions). Data were collected from April to August, 2014 and analyzed using t-tests and content analysis. The quantitative results showed that changes in personal growth (t=-6.33, pself-reflection program developed by this study was effective in helping nurses who had experienced the death of pediatric patients to achieve personal growth through self-reflection, and it was confirmed that the program can be applied in a realistic clinical nursing setting. Furthermore, it can be recommended as an intervention program for clinical nurses. © 2017 Korean Society of Nursing Science

    Purpose: Scoring of radiation pneumonitis (RP), a dose-limiting toxicity after thoracic radiochemotherapy, is subjective and thus inconsistent among studies. Here we investigated whether the extent of change in diffusing capacity of the lung for carbon monoxide (DLCO) after radiation therapy (RT) for non-small-cell lung cancer (NSCLC) could be used as an objective means of quantifying RP. Patients and Methods: We analyzed potential correlations between DLCO and RP in 140 patients who received definitive RT ({>=}60 Gy) with or without chemotherapy for primary NSCLC. All underwent DLCO analysis before and after RT. Post-RT DLCO values within 1 week of the RP diagnosis (Grade 0, 1, 2, or 3) were selected and compared with that individual's preradiation values. Percent reductions in DLCO and RP grade were compared by point biserial correlation in the entire patient group and in subgroups stratified according to various clinical factors. Results: Patients experiencing Grade 0, 1, 2, or 3 RP had median percentage changes in DLCO after RT of 10.7%, 13%, 22.1%, or 35.2%. Percent reduction in DLCO correlated with RP Grade {<=}1 vs. {>=}2 (p = 0.0004). This association held for the following subgroups: age {>=}65 years, advanced stage, smokers, use of chemotherapy, volume of normal lung receiving at least 20 Gy {>=}30%, and baseline DLCO or forced expiratory volume in 1 second {>=}60%. Conclusions: By correlating percent change in DLCO from pretreatment values at the time of diagnosis of RP with RP grade, we were able to identify categories of RP based on the change in DLCO. These criteria provide a basis for an objective scoring system for RP based on change in DLCO.

    The purpose of this study was to evaluate the predictive value of preoperative neck computed tomography (CT) in combination with histologic grading as a prognostic factor for patients with tongue carcinoma. Fifty-five patients with squamous cell carcinoma of the tongue were examined by CT prior to radical neck dissection. The locoregional failure and survival rates of these patients were analyzed in relation to their clinical characteristics, histologic grading (World Health Organization, WHO) based on tongue biopsy, and imaging diagnoses prior to surgery. Logistic multivariate regression analysis showed that both histologic grading and number of metastatic lymph nodes on CT were significant and independent prognostic factors in locoregional failure (p=0.009 and p=0.009, respectively). When the numebr of metastatic lymph nodes detected on preoperative neck CT were combined with the histologic grading for the evaluation, the five-year overall survival rates of A group (0 node with any Grade, or 1 node with Grade I-II) and B group (1 node with Grade III, or 2 or more nodes with any Grade) were 74.5% and 37.5%, respectively (p=0.001). The difference was more significant than histologic grading alone or the number of metastatic lymph nodes seen on CT alone. The combination of preoperative neck CT with histologic grading of the primary tumor is useful as a prognostic indicator for patients with tongue carcinoma. (author)

    This study aims to gain insight into patient-perceived communication barriers and facilitators at different stages after the diagnosis of malignant lymphoma. We have detected patterns to explain when these factors influence communication predominantly. A qualitative approach was applied, derived from the context mapping framework. A total of 28 patients completed a set of assignments about their experiences with provider-patient communication during medical consultations. Subsequently, these patients and nine companions shared their experiences during a semistructured (group) interview, which was recorded on audiotape. The audiotapes and assignments were analysed with MAXQDA software. From the patients' viewpoint, communicating effectively appears to depend on their own attributes (e.g. emotions), the health care professionals' attributes (e.g. attitude) and external factors (e.g. time pressure). Three patient communication states were identified: (i) overwhelmed, passive; (ii) pro-active, self-motivated; and (iii) proficient, empowered. Patients seem to behave differently in the three communication states. This study lists patient-perceived communication barriers and facilitators and identifies three different communication states, which indicate when certain barriers and facilitators are encountered. These findings may support health care professionals to tailor the provision of support and information and remove communication barriers accordingly. Additionally, they provide input for interventions to support patients in effective communication. Copyright © 2013 John Wiley & Sons, Ltd.

    Purpose: The aim of this study was to evaluate the toxicity, response, and survival of patients with relapsed high-grade gliomas after radiation therapy (RT) combined with lomustine (CCNU). Methods and Materials: Thirty-one patients with relapsed gliomas at least 6 months after completion of RT were reirradiated. Twenty-four patients had a pathological diagnosis of high-grade gliomas, whereas 7 had a radiological diagnosis of relapsed malignant gliomas. The study focused on patients with high-grade relapsed gliomas. A total dose of 34.5 Gy was delivered in 23 fractions over 4.5 weeks. Oral administration of CCNU (130 mg/m 2 ) was begun at the same time as RT, and was repeated every 6 weeks until disease progression, or up to 12 courses. Results: Twelve of 24 patients had surgery before RT plus CCNU treatment. Median interval between RT courses was 14 months (range 6-73). All patients received a complete course of RT, and 22 of 24 patients received at least one course of CCNU. Objective responses were seen in 14 evaluable patients: 3 with partial response, 5 with stable disease, and 6 with progressive disease. Duration of partial response was 20, 9, and 8 months. Median time to progression and overall survival from the onset of retreatment were 8.4 months (range 1-22) and 13.7 months (range 1-63+), respectively. One case of G4 thrombocytopenia was observed. Five patients had G1 or G2 leucopenia and 3 patients had G3 leucopenia. Moderate nausea and vomiting were reported in 4 patients. One patient, after one course of CCNU, refused further chemotherapy. No significant difference in survival from relapse was found between patients who underwent surgery before RT plus CCNU and those who received only RT plus CCNU (p = 0.74). Conclusion: Overall, the acute toxicity was moderate, and patient compliance was good. Reirradiation of high-grade glioma was associated with modest subjective and objective response rates. It is remarkable that median overall survival from relapse

    The purpose of our work was to determine a prevalence of depression and its distribution by grades in patients with a coronary heart disease, namely - with the myocardial infarction. The study involved 125 patients of average age 64.2±4.7 years, treated at cardiology department for myocardial infarction. The first stage was a depression screening using PHQ - 2 questionnaire. In case of positive answer to at least one question, we assessed the severity of depression using a PHQ-9 tool. We established, that PHQ-2 questionnaire questions for screening depressive disorders were positively answered by 80 patients (64.3%). Total signs of depression of various severity grades was diagnosed in 68 patients (54.4%). Minimal depression was diagnosed in 25 (36.8%) patients, mild depression - in 20 (29.4%) patients, moderately severe disease - in 16 (23.6%) patients, and severe depression - in 7 (10.2%) patients. The severity of depression was clearly related to age, gender of patients, comorbid diseases, and a history of MI and revascularization.

    Purpose: Myxofibrosarcoma (MFS) is a rare sarcoma with a predilection for multiple local recurrences (LR), for which optimal treatment has not been defined. We reviewed our experience to determine the impact of surgery and radiation therapy (RT) on pattern of recurrence, limb salvage, and overall survival (OS). Methods and Materials: Between 1995 and 2005, 36 patients with localized intermediate- or high-grade MFS were treated at our institution. Data on clinicopathologic features, treatments, and patient outcomes were reviewed and analyzed. Results: Median age was 72.5 years (range, 42–96 years). Median tumor size was 7.5 cm, and 34 tumors (94%) were high grade. All patients underwent surgery at our institution, including re-resections in 20 patients (56%) after initial surgery elsewhere. Margins were microscopically positive in 9 patients (25%). RT was given to 28 patients (78%) pre - and/or postoperatively. After a median follow-up of 3.5 years (range, 0.4–12.4 years), 11 patients (31%) developed LR. There were no significant predictors for LR on univariate analysis, including margin status or use of RT. Limb salvage was ultimately achieved in only 5 of 11 LRs (45%) because of multiple subsequent LRs. Distant recurrence (DR) occurred in 6 patients (17%). Median and 4-year OS were 96 months and 65%, respectively. Seven patients (19%) died of tumor-related causes, 6 of whom had DRs. On univariate analysis, tumor size was associated with OS. Conclusions: Despite aggressive surgery and RT, intermediate- and high-grade MFS are associated with a high rate of LR that adversely affects limb preservation. More aggressive local treatment strategies are necessary.

    Clinical relevance of low-frequency HIV-1 variants carrying drug resistance associated mutations (DRMs) is still unclear. We aimed to study the prevalence of low-frequency DRMs, detected by Ultra-Deep Sequencing (UDS) before antiretroviral therapy (ART) and at virological failure (VF), in HIV-1 infected patients experiencing VF on first-line ART. Twenty-nine ART-naive patients followed up in the ANRS-CO3 Aquitaine Cohort, having initiated ART between 2000 and 2009 and experiencing VF (2 plasma viral loads (VL) >500 copies/ml or one VL >1000 copies/ml) were included. Reverse transcriptase and protease DRMs were identified using Sanger sequencing (SS) and UDS at baseline (before ART initiation) and VF. Additional low-frequency variants with PI-, NNRTI- and NRTI-DRMs were found by UDS at baseline and VF, significantly increasing the number of detected DRMs by 1.35 fold (plow-frequency DRMs modified ARV susceptibility predictions to the prescribed treatment for 1 patient at baseline, in whom low-frequency DRM was found at high frequency at VF, and 6 patients at VF. DRMs found at VF were rarely detected as low-frequency DRMs prior to treatment. The rare low-frequency NNRTI- and NRTI-DRMs detected at baseline that correlated with the prescribed treatment were most often found at high-frequency at VF. Low frequency DRMs detected before ART initiation and at VF in patients experiencing VF on first-line ART can increase the overall burden of resistance to PI, NRTI and NNRTI.

    BACKGROUND: European guidelines recommend treatment of chronic hepatitis B virus infection (CHB) with the nucleos(t)ide analogs (NAs) entecavir or tenofovir. However, many European CHB patients have been exposed to other NAs, which are associated with therapy failure and resistance. The CAPRE study...... was performed to gain insight in prevalence and characteristics of NA resistance in Europe. METHODS: A survey was performed on genotypic resistance testing results acquired during routine monitoring of CHB patients with detectable serum hepatitis B virus DNA in European tertiary referral centers. RESULTS: Data...... from 1568 patients were included. The majority (73.8%) were exposed to lamivudine monotherapy. Drug-resistant strains were detected in 52.7%. The most frequently encountered primary mutation was M204V/I (48.7%), followed by A181T/V (3.8%) and N236T (2.6%). In patients exposed to entecavir (n = 102...

    Infertile males with varicocele have the highest percentage of sperm cells with damaged DNA, compared to other infertile groups. Antioxidant treatment is known to enhance the integrity of sperm DNA; however, there are no data on the effects in varicocele patients. We thus investigated the potential benefits of antioxidant treatment specifically in grade I varicocele males. Twenty infertile patients with grade I varicocele were given multivitamins (1500 mg L-Carnitine, 60 mg vitamin C, 20 mg coenzyme Q10, 10 mg vitamin E, 200 μg vitamin B9, 1 μg vitamin B12, 10 mg zinc, 50 μg selenium) daily for three months. Semen parameters including total sperm count, concentration, progressive motility, vitality, and morphology were determined before and after treatment. In addition, sperm DNA fragmentation and the amount of highly degraded sperm cells were analyzed by Sperm Chromatin Dispersion. After treatment, patients showed an average relative reduction of 22.1% in sperm DNA fragmentation (p = 0.02) and had 31.3% fewer highly degraded sperm cells (p = 0.07). Total numbers of sperm cells were increased (p = 0.04), but other semen parameters were unaffected. These data suggest that sperm DNA integrity in grade I varicocele patients may be improved by oral antioxidant treatment.

    Doxorubicin is one of the most active single agents in metastatic soft tissue sarcoma. This was the rationale for the evaluation og doxorubicin in an adjuvant situation for patients with high-grade soft tissue sarcoma in a randomized, Scandinavian, multicenter joint care program, which was carried out from January 1981 to February 1986, and included 240 patients. These patients comprised the base series for the investigations of the importance of the surgical margin and radiotherapy for local tumor control; the accuracy of malignancy grading and tumor typing; prognostic factors, including DNA content; and epidemiologic risk factors. The results showed that the use of doxorubicin as adjuvant chemotherapy did not have clinical benefit in patients with high-grade soft tissue sarcoma. The overall local tumor control was high (94 %) for radically operated on extremity-located tumors due to strict classification of surgical margins. The only risk factor for local recurrence was marginal surgery without radiotherapy with a four times higher risk than after compartmental or wide surgery. Twelve percent of the operations reported as radical were classified as marginal, demonstrating the importance of reevaluation of surgical margins, and in these patients the local recurrence rate was 37 %. The 5-year metastasis-free survival for the whole patients series was 55 %, with the extremes 79 % for the patients with no or only one risk factor and 0 % for those with four or five risk factors. The five prognostic factors found could be used for selection of high-risk patients for adjuvant chemotherapy in the future. The epidemiologic study gave limited support for an association between occupational phenoxy-acid exposure and soft tissue sarcoma development. (98 refs.)

    Although their neurocognitive performance is one of the major concerns of patients with high-grade gliomas (HGG) and although neurocognitive deficits have been described to be associated with negative outcome, neurocognitive rehabilitation is usually not integrated into the routine care of patients with malignant gliomas. In this pilot trial, a weekly group training session for attention, verbal, and memory skills was offered to patients with HGG with pre and post-training evaluation. Eleven patients, six with glioblastoma multiforme and five with WHO grade III gliomas, median age 50 years, with a Karnofsky performance score of 80-100 participated in ten group training sessions of 90 min. For evaluation at baseline and after the training by a neuropsychologist not involved in care or training of the patients, Trail Making Tests A and B (TMTA and TMTB), Hopkins Verbal Learning Test (HVLT), and the Controlled Oral Word Association Test (COWA) were used. Comparison of mean group differences between baseline and at post-training evaluation after 12 weeks revealed improvement across all neurocognitive variables. The patients showed a great diversity in their performances, with worsening, improvement, and stabilization. However, a significant group difference was detected only for the HVLT (score 19.6 +/- 8.9 at baseline, 23.6 +/- 8.8 after 12 weeks, P = 0.04). This pilot study shows that neurocognitive training in patients with HGG is feasible as group training with weekly sessions and might be able to induce improvements in attention and memory skills.

    The purpose of this study was to investigate continuity of care in the psychiatric healthcare system from the perspective of patients, including vulnerable groups such as immigrants and refugees. The study is based on 19 narrative interviews conducted with 15 patients with diverse migration backgrounds (immigrants, descendents, refugees, and ethnic Danes). Patients were recruited from a community psychiatric centre situated in an area with a high proportion of immigrants and refugees. Data were analysed through the lens of a theoretical framework of continuity of care in psychiatry, developed in 2004 by Joyce et al., which encompasses four domains: accessibility, individualised care, relationship base and service delivery. Investigating continuity of care, we found issues of specific concern to immigrants and refugees, but also commonalities across the groups. For accessibility, areas pertinent to immigrants and refugees include lack of knowledge concerning mental illness and obligations towards children. In terms of individualised care, trauma, additional vulnerability, and taboo concerning mental illness were of specific concern. In the domain of service delivery, social services included assistance with immigration papers for immigrants and refugees. In the relationship base domain, no differences were identified. Implications for priority area: The treatment courses of patients in the psychiatric field are complex and diverse and the patient perspective of continuity of care provides important insight into the delivery of care. The study highlights the importance of person-centred care irrespective of migration background though it may be beneficial to have an awareness of areas that may be of more specific concern to immigrants and refugees. The study sheds light on concerns specific to immigrants and refugees in a framework of continuity of care, but also commonalities across the patient groups.

    We have analyzed the correlation between the House-Brackmann (HB) scale and Facial Nerve Grading System 2.0 (FNGS 2.0) in patients with Bell palsy, and evaluated the usefulness of the new grading system. Sixty patients diagnosed with Bell palsy from May 2009 to December 2010 were evaluated using the HB scale and FNGS 2.0 scale during their initial visit, and after 3 and 6 weeks and 3 months. The overall intraclass correlation coefficient (ICC) was 0.908 (P=0.000) and the Spearman correlation coefficient (SCC) was 0.912 (P<0.05). ICC and SCC displayed differences over time, being 0.604 and 0.626, respectively, at first visit; 0.834 and 0.843, respectively, after 3 weeks; 0.844 and 0.848, respectively, after 6 weeks; and 0.808 and 0.793, respectively, after 3 months. There was a significant difference in full recovery, depending on the scale used (HB, P=0.000; FNGS 2.0, P<0.05). The exact agreements between regional assessment and FNGS 2.0 for the mouth, eyes, and brow were 72%, 63%, and 52%, respectively. FNGS 2.0 shows moderate agreement with HB grading. Regional assessment, rather than HB grading, yields stricter evaluation, resulting in better prognosis and determination of grade.

    To investigate power Doppler (PD) signal, grade and location and their association with radiographic progression in RA patients in remission. A prospective observational study was conducted in 125 consecutive RA patients in stable 28-joint DAS (DAS28) remission (⩾6 months) achieved on anti-TNF-α. At baseline, patients in stable remission underwent radiographic and US examination of the wrists and MCP, PIP and MTP joints. Semi-quantitative PD scoring (0-3) was recorded. We scored PD according to two locations: capsular or within synovial tissue without bone contact (location 1) and with bone contact or penetrating bone cortex (location 2). Radiographic progression was evaluated at the 1 year follow-up and defined as a change in van der Heijde-modified total Sharp score >0. Risk ratios (RRs) of radiographic progression according to presence, grade and location of PD were calculated. Four patients were excluded because of missing data. At baseline, 59/121 (48.7%) patients had a PD signal in one or more joints. PD location 2 was found in 74.6% patients (44/59). At the 1 year follow-up, 17/121 patients experienced radiographic progression: all had PD signal in one or more joints at baseline (RR 2.47, P location 2 (RR 3.49, P < 0.0001). Higher PD grades and PD in contact with/or penetrating bone are associated with radiographic progression in patients in DAS28 remission. © The Author 2017.

    Full Text Available OBJECTIVE: In the ANRS 139 TRIO trial, the use of 3 new active drugs (raltegravir, etravirine, and darunavir/ritonavir, resulted in a potent and sustained inhibition of viral replication in multidrug-resistant treatment-experienced patients. The aim of this virological sub-study of the ANRS 139 TRIO trial was to assess: (i the evolution of HIV-1 DNA over the first year; and (ii the association between baseline HIV-1 DNA and virological outcome. METHODS: Among the 103 HIV-1-infected patients included in the ANRS-139 TRIO trial, HIV-1 DNA specimens were available for 92, 84, 88, and 83 patients at Week (W0, W12, W24, and W48, respectively. Quantification of total HIV-1 DNA was performed by using the commercial kit "Generic HIV DNA Cell" (Biocentric, Bandol, France. RESULTS: Baseline median HIV-1 DNA of patients displaying virological success (n= 61, viral blip (n= 20, and virological failure (n = 11 were 2.34 log(10 copies/10(6 PBMC (IQR= 2.15-2.66, 2.42 (IQR = 2.12-2.48, and 2.68 (IQR= 2.46-2.83, respectively. Although not statistically significant, patients exhibiting virological success or viral blip had a tendency to display lower baseline HIV-1 DNA than patients experiencing virological failure (P = 0.06. Median decrease of HIV-1 DNA between baseline and W48 was -0.13 log(10 copies/10(6 PBMC (IQR = -0.34 to +0.10, mainly explained by the evolution from W0 to W4. No more changes were observed in the W4-W48 period. CONCLUSIONS: In highly-experienced multidrug-resistant patients, HIV-1 DNA slightly decreased during the first month and then remained stable during the first year of highly potent antiretroviral regimen. In this population, baseline HIV-1 DNA might help to better predict the virological response and to tailor clinical therapeutic management as more aggressive therapeutic choices in patients with higher baseline HIV-1 DNA.

    It has been suggested that MMPI-2 scoring requires removal of some items when assessing patients after a traumatic brain injury (TBI). Gass (1991. MMPI-2 interpretation and closed head injury: A correction factor. Psychological assessment, 3, 27-31) proposed a correction procedure in line with the hypothesis that MMPI-2 endorsement may be affected by symptoms of TBI. This study assessed the validity of the Gass correction procedure. A sample of patients with a TBI (n = 242), and a random subset of the MMPI-2 normative sample (n = 1,786). The correction procedure implies a failure of measurement invariance across populations. This study examined measurement invariance of one of the MMPI-2 scales (Hs) that includes TBI correction items. A four-factor model of the MMPI-2 Hs items was defined. The factor model was found to meet the criteria for partial measurement invariance. Analysis of the change in sensitivity and specificity values implied by partial measurement invariance failed to indicate significant practical impact of partial invariance. Overall, the results support continued use of all Hs items to assess psychological well-being in patients with TBI. © The Author 2014. Published by Oxford University Press. All rights reserved.

    The purpose of this review was to investigate within the literature the link between transcendent phenomena and peaceful death. The objectives were firstly to acknowledge the importance of such experiences and secondly to provide supportive spiritual care to dying patients. Information surrounding the aforementioned concepts is underreported in the literature. The following 4 key themes emerged: spiritual comfort; peaceful, calm death; spiritual transformation; and unfinished business The review established the importance of transcendence phenomena being accepted as spiritual experiences by health care professionals. Nevertheless, health care professionals were found to struggle with providing spiritual care to patients who have experienced them. Such phenomena are not uncommon and frequently result in peaceful death. Additionally, transcendence experiences of dying patients often provide comfort to the bereaved, assisting them in the grieving process. © The Author(s) 2015.

    Zygote intrafallopian transfer (ZIFT) is an effective option for patients who have experienced repeated implantation failures (RIF) in assisted reproductive technology (ART) treatment. However, advance planning for the day of the operation can be problematic. Using a hormone replacement cycle (HRC) makes it possible to plan for the day of ZIFT. In the present study, we evaluated whether HRC-ZIFT is useful for RIF patients who have experienced difficulties obtaining morphologically good embryos in vitro. A total of 55 patients with a history of five or more unsuccessful transfers received HRC-ZIFT between June 2008 and June 2013. The oocyte pick-ups were performed and the oocytes showing two pronuclei (2PN) were cryopreserved. After receiving more than five 2PN oocytes, the operation day was scheduled in advance, and as a consequence, a HRC was started and ZIFT was performed. The clinical outcomes were evaluated. The average age of the patients was 39.3 years, and the previous OPU and ET attempts numbered 7.5 and 6.9, respectively. The number of previously transferred embryos was 11.8, and the number of morphologically good embryos (MGEs) was only 1.2. The number of transferred 2PN oocytes was 6.7, and the subsequent pregnancy rate was 23.6 %. No ectopic or multiple pregnancies were observed, but there were 6 cases of miscarriage. Among RIF patients, in particular those who have difficulty obtaining MGEs in vitro, ZIFT might be a useful option. The HRC allows patients and medical staff to plan for the operation day in advance.

    This study describes the meaning and practice of holistic self-care for rehabilitation among Thai Buddhist trauma patients living in areas of political unrest where acts of terrorism occur. Eleven Thai Buddhist trauma patients were selected as specified. The data were collected by in-depth interviews between November 2011 and April 2012, and analyzed using the Van Manen method.Those interviewed described "holistic self-care for rehabilitation" as learning (1) to acquire a new life and (2) to bear the increased demands of care as a chronic disease. Health care responses fell into 3 categories: (1) improving physical self-sufficiency and rehabilitation by increasing muscle strength, pain management, and pressure sores; (2) improving psychological well-being by applying positive thinking, making an effort to live independently, and following a set of religious practices; and (3) finding harmony in life through caution and a willingness to adjust one's lifestyle. Although the participants seemed to adapt well to their new lifestyles, extensive support from health care professionals was necessary. This study promotes better understanding of the holistic health care experiences the survivors of trauma have as a result of an unstable political situation that includes aspects of social unrest and terrorism.

    Inter-hospital patient transports are required around the clock. During these transports it is the responsibility of the accompanying nurse specialists to ensure their patient's safety, while at the same time providing optimal nursing care in an unusual and often stressful situation. The aim of this study was to explore and describe the nurse specialists' cause of worries and concerns (WaC) and how they manage these. An explorative and qualitative design based on the critical incident technique was used. Interviews were conducted with 30 nurse specialists within the fields of anaesthetic, intensive and pre-hospital care in the south of Sweden. WaC felt by the nurse specialists were based on being unable to influence their work situation, or carry out their tasks as expected. Their responses to these unusual situations were resolved by using internal (acquired knowledge and experience) and external resources (consulting colleagues having different competences). A safe working environment improves the possibility to deliver a satisfactory work performance. Shared experiences and communication between colleagues should be encouraged; teamwork should be enhanced by the implementation of local and national training courses, and unambiguous work guidelines should be given.

    To study the frequency of steatosis and observe the relation between steatosis and grade of fibrosis in patients with hepatitis C. This descriptive case series study was undertaken at Liaquat University of Medical and Health Sciences hospital from July 2005 to November 2007. It included 158 PCR-positive hepatitis C cases with genotype 3. Patients demographic data was enrolled in well designed proforma BMI was calculated and history of diabetes mellitus was obtained. Liver biopsy was done after written consent and was sent for grading of fibrosis and steatosis. T-test was applied for Continuous variables whereas stage of fibrosis was compared with grade of steatosis, BMI and age by chi-square test. 0.05 was made a level of Significance. This study included 158 patients out of which 109 (69%) were male and 49(31%) were female. The mean age of the patient was 36.8 +- 9.8.The BMI was 30 in 19 (12%) of cases. The steatosis was found in 71(45%) of cases. Mild ( 60% hepatocytes involved) steatosis in 12(7.5%) cases. A strong correlation between steatosis score and fibrosis stage was observed in our study (P= < 0.001) whereas no relationship was observed between BMI (P 0.67) or age (P =0.39) with stage of steatosis. This study showed that increased steatosis is associated with worsening fibrosis suggesting a possible role for steatosis in the acceleration of liver disease in HCV Patients and efforts to control steatosis may therefore have an important role in halting HCV liver disease progression.

    The aim of the study: was to determine how far general practice teams are prepared to relieve family caregivers of palliative patients from their caregiving burden, the support they actually offer, and where they identify needs for improvement. Method: Focus groups and interviews on the issues of identification and support of family caregivers were conducted with practice teams (general practitioners, GPs, and medical assistants, MAs) and the results qualitatively analyzed. Results: 21 participants (14 GPs, 7 MAs) from 13 practices identified burdened family caregivers, thereupon offered support and provided contact details to local consultation services. They suggested to family caregivers that they should use their social network to create room for meeting their own needs. Conclusions: Practice teams use a multitude of individualized and unsystematic approaches to support family caregivers. In further studies within the framework of this project, systematic approaches will be identified and tried out. © Georg Thieme Verlag KG Stuttgart · New York.

    The utilization of mobile applications (apps) as educational resources for patients highlights the need for an objective method of evaluating the quality of health care-related mobile apps. In this study, a quantified rubric was developed to objectively grade publicly available dermatology mobile apps with the primary focus of patient education. The rubric included 5 criteria thought to be most important in evaluating the adequacy of these apps in relaying health information to patients: educational objectives, content, accuracy, design, and conflict of interest. A 4-point scale was applied to each criterion. The use of this objective rubric could have implications in the evaluation and recommendation of mobile health care apps as a vital educational resource for patients.

    Facial and vocal emotions contribute to sustain efficient social relationships. Brain disease may impair their identification. In the case of slow-growth tumors (Low Grade Gliomas [LGG]) or sudden stroke (cerebrovascular accidents [CVA]), the lesions induce contrasted plasticity and reorganisation processes. We compared the facial, vocal and intermodal identification of six emotions (happiness, fear, angriness, sadness, disgust and neutral) of three groups: patients with LGG before and after tumor resection, patients with CVA and control subjects. In LGG patients, the results revealed less efficient performances after tumor resection and in CVA patients weak performances regarding negative emotions. The intermodal condition (simultaneous visual and vocal association) improved performances in all groups and enabled equivalent performance in CVA subjects compared with control subjects. The intergroup differences may be related to variable brain plasticity as a function of type and rapidity of brain injury. Intermodal processing appears to be a compensatory condition.

    Full Text Available The Southwest coastal plain of Taiwan is an endemic area of arsenic contamination. Residents who lived there before the 1970s and who used raw groundwater for drinking have a higher risk of arsenic poisoning. In 1968, Tseng et al. described Blackfoot disease as a peripheral vascular disease caused by chronic exposure to arsenic, thereby introducing the concept of arsenic-induced systemic illness in Taiwan. Multiple Bowen's disease (BD is one of the characteristic consequences of chronic arsenic poisoning and it usually presents as cutaneous carcinoma in situ. Multiple BD can also be associated with squamous cell carcinoma and basal cell carcinoma of the skin, as well as lung, liver, gastrointestinal, and bladder cancers. We encountered a 79-year-old male from Yun-Lin, a county in Southwest Taiwan, who presented with a progressing tumor in his right anterior chest wall. In addition, numerous keratoses and scaly skin lesions were noted on his trunk and extremities, some of which were combined with erosions. The patient was diagnosed with chronic arsenic poisoning with multiple BD and the huge tumor was confirmed as an epithelioid malignant peripheral nerve sheath tumor.

    This study provides an evaluation of group schema therapy (ST) for inpatient treatment of patients with personality pathology who did not respond to previous psychotherapeutic interventions. Forty-two patients were assessed pre- and posttreatment, and 35 patients were evaluated at follow-up 6 months later. The results showed a dropout rate of 35%. Those who dropped out did not differ from those who completed treatment with regard to demographic and clinical variables; the only exception was that those who dropped out showed a lower prevalence of mood disorders. Furthermore, intention-to-treat analyses showed a significant improvement in maladaptive schemas, schema modes, maladaptive coping styles, mental well-being, and psychological distress after treatment, and these improvements were maintained at follow-up. On the other hand, there was no significant change in experienced parenting style as self-reported by patients. Changes in schemas and schema modes measured from pre- to posttreatment were predictive of general psychological distress at follow-up. Overall, these preliminary findings suggest that positive treatment results can be obtained with group ST-based inpatient treatment for patients who did not respond to previous psychotherapeutic interventions. Moreover, these findings are comparable with treatment results for patients without such a nonresponsive treatment history. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    One of the primary dose-limiting toxicities during thoracic irradiation is acute esophagitis (AE). The aim of this study is to investigate dosimetric and clinical predictors for AE grade ≥ 2 in patients treated with accelerated radiotherapy for locally advanced non-small cell lung cancer (NSCLC). 66 NSCLC patients were included in the present analysis: 4 stage II, 44 stage IIIA and 18 stage IIIB. All patients received induction chemotherapy followed by dose differentiated accelerated radiotherapy (DART-bid). Depending on size (mean of three perpendicular diameters) tumors were binned in four dose groups: <2.5 cm 73.8 Gy, 2.5–4.5 cm 79.2 Gy, 4.5–6 cm 84.6 Gy, >6 cm 90 Gy. Patients were treated in 3D target splitting technique. In order to estimate the normal tissue complication probability (NTCP), two Lyman models and the cutoff-logistic regression model were fitted to the data with AE ≥ grade 2 as statistical endpoint. Inter-model comparison was performed with the corrected Akaike information criterion (AIC c ), which calculates the model’s quality of fit (likelihood value) in relation to its complexity (i.e. number of variables in the model) corrected by the number of patients in the dataset. Toxicity was documented prospectively according to RTOG. The median follow up was 686 days (range 84–2921 days), 23/66 patients (35 %) experienced AE ≥ grade 2. The actuarial local control rates were 72.6 % and 59.4 % at 2 and 3 years, regional control was 91 % at both time points. The Lyman-MED model (D50 = 32.8 Gy, m = 0.48) and the cutoff dose model (D c = 38 Gy) provide the most efficient fit to the current dataset. On multivariate analysis V38 (volume of the esophagus that receives 38 Gy or above, 95 %-CI 28.2–57.3) was the most significant predictor of AE ≥ grade 2 (HR = 1.05, CI 1.01–1.09, p = 0.007). Following high-dose accelerated radiotherapy the rate of AE ≥ grade 2 is slightly lower than reported for concomitant radio-chemotherapy with the

    Rates of obesity have increased globally and weight stigma is commonly experienced by people with obesity. Feeling stigmatised because of one's weight can be a barrier to healthy eating, physical activity and to seeking help for weight management. The aim of this study was to identify predictors of perceived weight among middle-older aged patients with obesity attending general practices in socioeconomically disadvantaged urban areas of Australia. As part of a randomised clinical trial in Australia, telephone interviews were conducted with 120 patients from 17 general practices in socioeconomically disadvantaged of Sydney and Adelaide. Patients were aged 40-70 years with a BMI ≥ 30 kg/m 2 . The interviews included questions relating to socio-demographic variables (e.g. gender, language spoken at home), experiences of weight-related discrimination, and the Health Literacy Questionnaire (HLQ). Multi-level logistic regression data analysis was undertaken to examine predictors of recent experiences of weight-related discrimination ("weight stigma"). The multi-level model showed that weight stigma was positively associated with obesity category 2 (BMI = 35 to stigma and gender, age, education or the other HLQ domains examined. Weight stigma disproportionately affected the patients with obesity most in need of support to manage their weight: those with more severe obesity, from non-English speaking backgrounds and who were not in employment. Additionally, those who had experienced weight stigma were less able to actively engage with healthcare providers further compounding their disadvantage. This suggests the need for a more proactive approach to identify weight stigma by healthcare providers. Addressing weight stigma at the individual, system and population levels is recommended. The trial was registered with the Australian Clinical Trials Registry ACTRN126400102162 .

    Full Text Available Purpose: To study the effect of high grade varicocele treatment in infertile patients. Materials and Methods: Seventy-five patients were selected by the following criteria: infertility persisting for more than 1 year; abnormal semen parameters; no other infertility-related disease; no obvious causes of infertility in the subject’s partner; basal eco-color Doppler ultrasound demonstrating continuous reflux in the spermatic vein. All patients considered for the study had at least a six months period from the diagnosis to the surgery due to waiting list, choice of the patient or time needed to complete diagnostic evaluation of the couple. The surgical procedure was performed through an inguinal approach. All enrolled patients were counseled to have unprotected intercourse during the ovulation period in order to maximize the probability of pregnancy within the 6-month preoperative period. The achievement of pregnancy and semen parameters were recorded during the preoperative and postoperative period. Results: Two of the seventy-five patients were excluded because of persistent varicocele after surgery. The preoperative pregnancy rate was 1.3% (1 couple. The postoperative pregnancy rate was 42.5%. The stratification of pregnancies by semester showed a significantly higher rate in the first postoperative period (p = 0.0012. Mean time to conception was 13.5 months. Mean preoperative sperm count was 17.6x10 6 /mL compared to 19.7x10 6 /mL in the postoperative period (p < 0.0001. Mean percentage of progressive sperm motility was 13.7%, compared to 17.6% in the postoperative period (p < 0.0001. Mean percentage of normal sperm morphology was 7.6%, compared to 15.2% postoperatively (p < 0.0001. Conclusion: Surgical treatment of high grade varicocele proved to effectively treat associated infertility by improving seminal parameters and pregnancy rate in our patient cohort.

    One hundred and eighteen patients with nodular non-Hodgkin's lymphoma were randomized to receive either chemotherapy alone or chemotherapy plus radiotherapy (total nodal or involved field irradiation). Although the complete remission rate was similar in the three programs (about 90%) the relapse-free survival rate (RFS) among patients with complete remission was significantly higher in the groups treated with chemotherapy plus radiotherapy than among those treated with chemotherapy alone. The 7-year RFS in the groups treated with total node irradiation and involved field irradiation was 71% and 66% respectively, compared to only 33% in the group treated by chemotherapy alone (p<0.01). The results suggest that combined chemoradiotherapy may achieve complete long-term remission and potential cure in more than 60% of patients with nodular low-grade non-Hodgkin's lymphoma. Toxicity was moderate in all three arms. Bulky disease and a high level of lactic dehydrogenase were associated with a poor prognosis. (orig.)

    Full Text Available Background & objectives : Though diabetes affects multiple organs, most studies highlight the occurence of only one complication in isolation. We conducted a hospital-based study to estimate the co-existence of significant systemic co-morbid conditions in patients with varying grades of diabetic retinopathy. Methods : A total of 170 consecutive patients with diabetic retinopathy were prospectively recruited for the study between June 2009 to June 2010 at a tertiary care eye centre in north India. Retinopathy was graded by fundus biomicroscopy and fundus photography and classified into three categories (mild-moderate nonproliferative retinopathy, proliferative retinopathy requiring only laser and proliferative retinopathy requiring surgery. Nephropathy was classified by calculating the six variable estimated glomerular filtration rate (eGFR for all patients. Nerve conduction studies and clinical assessment were used to determine presence of neuropathy. Co-existence of macrovascular disease and peripheral vascular disease was also ascertained. Results : The percentages of patients with overt nephropathy in the three groups were 19.2, 38.0 and 41.2, respectively. Significant linear trends were observed for serum creatinine (P=0.004, albumin (P=0.017 and eGFR (P=0.030. A higher per cent had abnormal nerve conduction on electrophysiology than that diagnosed clinically (65.4 vs. 44.2, 76.0 vs. 40.0 and 64.8 vs. 48.6, respectively. The odds ratio (95% CI for co-existence of nephropathy, neuropathy, CVA (cerebrovascular accidents and PVD (peripheral vascular disease was 2.9, 0.9, 4.8 and 3.5, respectively. Independent of retinopathy severity, patients with clinically significant macular oedema (CSME had a higher percentage of nephropathy ( p0 < 0.005. Interpretation & conclusions : The co-existence of overt nephropathy, nerve conduction based neuropathy and macrovascular co-morbidity in patients with early grades of diabetic retinopathy was significant

    OBJECTIVE World Health Organization grade II gliomas are infiltrating tumors that inexorably progress to a higher grade of malignancy. However, the time to malignant transformation is quite unpredictable at the individual patient level. A wild-type isocitrate dehydrogenase (IDH-wt) molecular profile has been reported as a poor prognostic factor, with more rapid progression and a shorter survival compared with IDH-mutant tumors. Here, the oncological outcomes of a series of adult patients with IDH-wt, diffuse, WHO grade II astrocytomas (AII) who underwent resection without early adjuvant therapy were investigated. METHODS A retrospective review of patients extracted from a prospective database who underwent resection between 2007 and 2013 for histopathologically confirmed, IDH-wt, non-1p19q codeleted AII was performed. All patients had a minimum follow-up period of 2 years. Information regarding clinical, radiographic, and surgical results and survival were collected and analyzed. RESULTS Thirty-one consecutive patients (18 men and 13 women, median age 39.6 years) were included in this study. The preoperative median tumor volume was 54 cm 3 (range 3.5-180 cm 3 ). The median growth rate, measured as the velocity of diametric expansion, was 2.45 mm/year. The median residual volume after surgery was 4.2 cm 3 (range 0-30 cm 3 ) with a median volumetric extent of resection of 93.97% (8 patients had a total or supratotal resection). No patient experienced permanent neurological deficits after surgery, and all patients resumed a normal life. No immediate postoperative chemotherapy or radiation therapy was given. The median clinical follow-up duration from diagnosis was 74 months (range 27-157 months). In this follow-up period, 18 patients received delayed chemotherapy and/or radiotherapy for tumor progression. Five patients (16%) died at a median time from radiological diagnosis of 3.5 years (range 2.6-4.5 years). Survival from diagnosis was 77.27% at 5 years. None of the

    To report the surgical outcomes of graded versus ungraded inferior oblique anterior transposition (IOAT) in treatment of patients with asymmetric dissociated vertical deviation (DVD) and bilateral inferior oblique overaction (IOOA). A total of 74 eyes of 37 patients with asymmetric DVD (interocular difference of ≥5 Δ ) and bilateral IOOA of > +1 were included in this randomized clinical trial. In the ungraded group (n = 18), both inferior oblique muscles were sutured at the inferior rectus level; in the graded group (n = 19), the inferior oblique muscles of eyes with more DVD were sutured at the level of the inferior rectus and inferior oblique muscles of eyes with less DVD were sutured 2 mm posterior to the level of the inferior rectus muscle. DVD was significantly reduced in each group (P < 0.001 for both). Although the postoperative mean difference of asymmetry of DVD was less in the ungraded group compared to the graded group (1.2 ± 1.9 vs 3.2 ± 1.2 [P = 0.001]), the absolute amounts of reduction of DVD asymmetry were similar (4.3 ± 2.3 vs 4.4 ± 3.1 [P = 0.78]). IOOA and V patterns were also reduced postoperatively. Each method of IOAT was effective in reducing DVD, asymmetry, IOOA, and V patterns.

    Objective. To examine new investigative biomarkers and their relevance for radiographic severity in knee osteoarthritis. Methods. The group comprised 63 patients with 73 knees examined. Patients were divided according to radiographic severity to allow for comparison of biomarker levels. Hyaluronic acid (HA), matrix metalloproteases (MMP-1, MMP-3 and MMP-13), tissue inhibitors of metalloproteases (TIMP-1 and TIMP-2), platelet-derived growth factor (PDGF-AB), transformed growth factor (TGF-β), vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF) and insulin-like growth factor (IGF-I) were measured on synovial fluid and in plasma releasate at a single time point. Principal component analysis (PCA) followed by analysis of covariance were applied to evaluate data. Results. Four different groups of biomarker were identified in plasma releasates. The first (platelet number, PDGF-AB and TGF-β) and second groups (HA and IGF-I) were related to radiographic severity, P = .005 and P = .022, respectively. The third (MMP-1 and TIMP-2) and fourth groups (MMP-3 and TIMP-1) represented the catabolic balance, but were not associated to radiographic grading. Three different clusters of biomarkers were found in synovial fluid but did not show any significant association to radiographic grading. Conclusions. New imaging approaches to assess structural deterioration and correlation with biomarker levels are warranted to advance in OA research. PMID:20130801

    Low brain tissue glucose levels after acute brain injury are associated with poor outcome. Whether enteral nutrition (EN) reliably increases cerebral glucose levels remains unclear. In this retrospective analysis of prospectively collected observational data, we investigate the effect of EN on brain metabolism in 17 poor-grade subarachnoid hemorrhage (SAH) patients undergoing cerebral microdialysis (CMD) monitoring. CMD-values were obtained hourly. A nutritional intervention was defined as the clinical routine administration of EN without supplemental parenteral nutrition. Sixty-three interventions were analyzed. The mean amount of EN per intervention was 472.4 ± 10.7 kcal. CMD-glucose levels significantly increased from 1.59 ± 0.13 mmol/l at baseline to a maximum of 2.03 ± 0.2 mmol/l after 5 h (p  40) and the microdialysis probe location. The increase in CMD-glucose was directly dependent on the magnitude of increase of serum glucose levels (p = 0.007). No change in CMD-lactate, CMD-pyruvate, CMD-LPR, or CMD-glutamate (p > 0.4) was observed. Routine EN also increased CMD-glucose even if baseline concentrations were critically low ( < 0.7 mmol/l, neuroglucopenia; p < 0.001). These results may have treatment implications regarding glucose management of poor-grade aneurysmal SAH patients.

    Previously published randomized evidence did not report a survival advantage for patients diagnosed with grade IV glioma who were treated with stereotactic radiosurgery followed by external beam radiation therapy and chemotherapy when compared to patients treated with external beam radiation therapy and chemotherapy alone. In recent years, gamma knife radiosurgery has become increasingly popular as a salvage treatment modality for patients diagnosed with recurrent high-grade glioma. The purpose of this article is to review the efficacy of gamma knife radiosurgery for patients who suffer from this malignancy. Retrospective, prospective, and randomized clinical studies published between the years 2000 and 2012 analyzing gamma knife radiosurgery for patients with high-grade glioma were reviewed. After assessing patient age, Karnofsky performance status, tumor histology, and extent of resection, gamma knife radiosurgery is a viable, minimally invasive treatment option for patients diagnosed with recurrent high-grade glioma. The available prospective and retrospective evidence suggests that gamma knife radiosurgery provides patients with a high local tumor control rate and a median survival after tumor recurrence ranging from 13 to 26 months. Gamma knife radiosurgery followed by chemotherapy for recurrent high-grade glioma may provide select patients with increased levels of survival. However, further investigation into this matter is needed due to the limited number of published reports. Additional clinical research is also needed to analyze the efficacy and radiation-related toxicities of fractionated gamma knife radiosurgery due to its potential to limit treatment-associated morbidity. Gamma knife radiosurgery is a safe and effective treatment option for select patients diagnosed with recurrent high-grade glioma. Although treatment outcomes have improved, further evidence in the form of phase III randomized trials is needed to assess the durability of treating

    Arthroscopic debridement has been used to treat patients with degenerative knee osteoarthritis, although there is sometimes conflicting evidence documenting its efficacy. This study evaluates the success of arthroscopic debridement in elderly patients with grade III and IV chondromalacia of the knee as measured by patient satisfaction and the need for additional surgery. From December 1998 to August 2001, a total of 102 consecutive cases of knee arthroscopy in 99 patients > 60 years were performed. Average follow-up was 34 months (range: 7-104 months). Patients were asked about their satisfaction using a visual analog scale, and the presence of meniscal lesions during arthroscopy and the treatment for these lesions were evaluated. Knees also were assessed for articular surface degeneration using Outerbridge's classification for chondromalacia. The need for and type of additional surgery was evaluated. During arthroscopy, meniscal lesions requiring a partial meniscectomy were found in 95 knees. Chondromalacia was found in 92 knees; 53 knees had grade I or II chondromalacia and 39 knees had grade III or IV chondromalacia. Additional surgery was performed in 17 knees. Mean patient satisfaction score was 73 (range: 50-100) in the 39 knees with grade III or IV chondromalacia after arthroscopic debridement was performed. These findings suggest arthroscopic debridement in elderly patients has a place in the treatment algorithm for grade III or IV chondromalacia of the knee.

    Physical functioning can be assessed by different approaches that are characterized by increasing levels of individual appraisal. There is insufficient insight into which approach is the most informative in patients with ankylosing spondylitis (AS) compared with control subjects. The objective of this study was to compare patients with AS and control subjects regarding 3 approaches of functioning: experienced ability to perform activities (Bath Ankylosing Spondylitis Functional Index [BASFI]), self-reported amount of physical activity (PA) (Baecke questionnaire), and the objectively measured amount of PA (triaxial accelerometer). This case-control study included 24 AS patients and 24 control subjects (matched for age, gender, and body mass index). Subjects completed the BASFI and Baecke questionnaire and wore a triaxial accelerometer. Subjects also completed other self-reported measures on disease activity (Bath AS Disease Activity Index), fatigue (Multidimensional Fatigue Inventory), and overall health (EuroQol visual analog scale). Both groups included 14 men (58%), and the mean age was 48 years. Patients scored significantly worse on the BASFI (3.9 vs 0.2) than their healthy peers, whereas PA assessed by Baecke and the accelerometer did not differ between groups. Correlations between approaches of physical functioning were low to moderate. Bath Ankylosing Spondylitis Functional Index was associated with disease activity (r = 0.49) and physical fatigue (0.73) and Baecke with physical and activity related fatigue (r = 0.54 and r = 0.54), but total PA assessed by accelerometer was not associated with any of these experience-based health outcomes. Different approaches of the concept physical functioning in patients with AS provide different information. Compared with matched control subjects, patients with AS report more difficulties but report and objectively perform the same amount of PA.

    . Despite of high relevance for both clinical diagnostics and research, individual in vivo WSA definition is fairly limited to date. Thus, this study proposes a standardized segmentation approach to delineate individual WSAs by use of time-to-peak (TTP) maps and investigates spatial variability...... of individual WSAs. Methods: We defined individual watershed masks based on relative TTP increases in 30 healthy elderly persons and 28 patients with unilateral, high-grade carotid stenosis, being at risk for watershed-related hemodynamic impairment. Determined WSA location was confirmed by an arterial transit...... time atlas and individual super-selective arterial spin labeling. We compared spatial variability of WSA probability maps between groups and assessed TTP differences between hemispheres in individual and group-average watershed locations. Results: Patients showed significantly higher spatial...

    Limited focus has been placed on neuropsychological patient profiles after spontaneous subarachnoid hemorrhage (sSAH). We conducted a prospective controlled study in good-grade sSAH patients to evaluate the time course of treatment-specific differences in cognitive processing after sSAH. Twenty-six consecutive sSAH patients were enrolled (drop out n=5). Nine patients received endovascular aneurysm occlusion (EV), 6 patients were treated microsurgically (MS), and 6 patients with perimesencephalic SAH (pSAH) underwent standardized intensive medical care. No patient experienced serious vasospasm-related ischemic or hemorrhagic complications. All patients were subjected to neuropsychological self-report assessment (36-Item Short Form Health Survey and ICD-10-Symptom-Rating questionnaire) subacutely (day 11 - 35) after the onset of bleeding (t1) and at the 6-month follow-up (FU; t 2 ). From t1 to t 2 , MS and EV patients significantly improved in physical functioning (Pfi; p=.001 each) and the physical component summary (p=.010 vs. p=.015). Bodily pain (Pain; MS p=.034) and general health perceptions (EV p=.014) significantly improved, and nutrition disorder (EV p=.008) worsened. At FU, MS patients reported significantly better Pfi (vs. EV p=.046), less Pain (vs. EV p=.040), and more depression (vs. pSAH p=.035). Group-rate analyses of test differences showed a significant alleviation in nutrition disorder in MS (vs. EV p=.009). All sSAH groups reported a significant deterioration in health. Though both MS and EV patients, improved in several physical items over time, our data suggest a better short-term Pfi, less Pain and improved nutrition disorder in surgically treated patients. pSAH patients performed significantly better in various aspects of physical and psychological functioning than patients with aneurysmal SAH.

    Despite many claims of functional reorganization following tumour surgery, empirical studies that investigate changes in functional activation patterns are rare. This study investigates whether functional recovery following surgical treatment in patients with a low-grade glioma in the left hemisphere is linked to inter-hemispheric reorganization. Based on literature, we hypothesized that reorganization would induce changes in the spatial pattern of activation specifically in tumour homologue brain areas in the healthy right hemisphere. An experimental group (EG) of 14 patients with a glioma in the left hemisphere near language related brain areas, and a control group of 6 patients with a glioma in the right, non-language dominant hemisphere were scanned before and after resection. In addition, an age and gender matched second control group of 18 healthy volunteers was scanned twice. A verb generation task was used to map language related areas and a novel technique was used for data analysis. Contrary to our hypothesis, we found that functional recovery following surgery of low-grade gliomas cannot be linked to functional reorganization in language homologue brain areas in the healthy, right hemisphere. Although elevated changes in the activation pattern were found in patients after surgery, these were largest in brain areas in proximity to the surgical resection, and were very similar to the spatial pattern of the brain shift following surgery. This suggests that the apparent perilesional functional reorganization is mostly caused by the brain shift as a consequence of surgery. Perilesional functional reorganization can however not be excluded. The study suggests that language recovery after transient post-surgical language deficits involves recovery of functioning of the presurgical language system. Copyright © 2014 Elsevier Ltd.

    Purpose: To assess observer-based vs. patient self-reported scoring of xerostomia after intensity-modulated radiotherapy (IMRT) of head-and-neck (HN) cancer. Methods: A total of 38 patients who had received IMRT for HN cancer underwent xerostomia evaluations 6 to 24 months after completion of therapy using three methods each time: (1) Grading by 3 observers according to the Radiotherapy Oncology Group/European Organization for Research and Therapy of Cancer (RTOG/EORTC) system; (2) patient self-reported validated xerostomia questionnaire (XQ); and (3) major salivary gland flow measurements. Results: The interobserver agreement regarding the RTOG/EORTC grades was moderate: κ-coefficient 0.54 (95% CI = 0.31-0.76). The correlations between the average RTOG/EORTC grades and the salivary flow rates were not statistically significant. A trend for significant correlation was observed between these grades and the percent (relative to the pretherapy) nonstimulated salivary flow rates (p = 0.07), but not with the percent stimulated flow rates. Better correlations were found between grading made more than the median time (15 min) after the last liquid sipping and the nonstimulated (but not the stimulated) flows compared with grading made shortly after sipping. In contrast, significant correlations were found between the XQ scores and the nonstimulated (p < 0.005) and the stimulated (p < 0.005) salivary flow rates, as well as with the percentages of the corresponding pretherapy values (p = 0.002 and 0.038, respectively). No significant correlation was found between the RTOG/EORTC grades and the XQ scores. The observer-based grades underestimated the severity of xerostomia compared with the patient self-reported scores. Conclusions: Patient self-reported, rather than physician-assessed scores, should be the main end points in evaluating xerostomia

    promotion. Therefore, health professionals should be encouraged by their leaders to engage in interdisciplinary collaboration with researchers in academia in developing new interventions for improving practice. Researchers who engage in such projects should be prepared to take on long-term collaboration. Implications for practice: •\tThere is a need to develop the field of health promotion for long-term conditions, and especially a need to develop interventions to strengthen individuals' capacity for health, empowerment and recovery •\tAn interdisciplinary project team is an advantage when developing interventions that aim to address the challenges experienced by individuals living with long-term conditions •\tPartnership with patients in the design and testing of new interventions is necessary to maximise the relevance and suitability of the intervention

    To examine how palliative medicine doctors engage patients in end-of-life (hereon, EoL) talk. To examine whether the practice of "eliciting and responding to cues", which has been widely advocated in the EoL care literature, promotes EoL talk. Conversation analysis of video- and audio-recorded consultations. Unselected terminally ill patients and their companions in consultation with experienced palliative medicine doctors. Outpatient clinic, day therapy clinic, and inpatient unit of a single English hospice. Doctors most commonly promoted EoL talk through open elaboration solicitations; these created opportunities for patients to introduce-then later further articulate-EoL considerations in such a way that doctors did not overtly ask about EoL matters. Importantly, the wording of elaboration solicitations avoided assuming that patients had EoL concerns. If a patient responded to open elaboration solicitations without introducing EoL considerations, doctors sometimes pursued EoL talk by switching to a less participatory and more presumptive type of solicitation, which suggested the patient might have EoL concerns. These more overt solicitations were used only later in consultations, which indicates that doctors give precedence to patients volunteering EoL considerations, and offer them opportunities to take the lead in initiating EoL talk. There is evidence that doctors treat elaboration of patients' talk as a resource for engaging them in EoL conversations. However, there are limitations associated with labelling that talk as "cues" as is common in EoL communication contexts. We examine these limitations and propose "possible EoL considerations" as a descriptively more accurate term. Through communicating-via open elaboration solicitations-in ways that create opportunities for patients to volunteer EoL considerations, doctors navigate a core dilemma in promoting EoL talk: giving patients opportunities to choose whether to engage in conversations about EoL whilst

    We conducted an open-label, randomized, phase 3 trial to determine the efficacy and safety of sofosbuvir and ribavirin, with and without peginterferon-alfa, in treatment-experienced patients with cirrhosis and hepatitis C virus (HCV) genotype 2 infection and treatment-naïve or treatment-experienced patients with HCV genotype 3 infection. The study was conducted at 80 sites in Europe, North America, Australia, and New Zealand Patients were randomly assigned (1:1:1) to groups given sofosbuvir and ribavirin for 16 weeks (n = 196); sofosbuvir and ribavirin for 24 weeks (n = 199); or sofosbuvir, peginterferon-alfa, and ribavirin for 12 weeks (n = 197). The primary end point was the percentage of patients with HCV RNA <15 IU/mL 12 weeks after stopping therapy (sustained virologic response [SVR12]). From October 2013 until April 2014, we enrolled and treated 592 patients-48 with genotype 2 HCV and compensated cirrhosis who had not achieved SVR with previous treatments and 544 with genotype 3 HCV (279 treatment-naïve and 265 previously treated). Overall, 219 patients (37%) had compensated cirrhosis. The last post-treatment week 12 patient visit was in January 2015. Rates of SVR12 among patients with genotype 2 HCV were 87% and 100%, for those receiving 16 and 24 weeks of sofosbuvir and ribavirin, respectively, and 94% for those receiving sofosbuvir, peginterferon, and ribavirin for 12 weeks. Rates of SVR12 among patients with genotype 3 HCV were 71% and 84% in those receiving 16 and 24 weeks of sofosbuvir and ribavirin, respectively, and 93% in those receiving sofosbuvir, peginterferon, and ribavirin. On-treatment virologic failure occurred in 3 patients with HCV genotype 3a receiving sofosbuvir and ribavirin for 24 weeks. The most common adverse events were fatigue, headache, insomnia, and nausea. Overall, 1% of patients discontinued treatment due to adverse events. Among patients with genotype 3 HCV infection, including a large proportion of treatment-experienced

    Neuropathy is an important complication that may limit treatment options for patients with multiple myeloma. Previous studies have focused on treatment efficacy and have shown that retreatment with bortezomib (BTZ) is an effective treatment option. The goal of this study was to focus on the clinical manifestations of peripheral neuropathy (PN) and to retrospectively compare the incidence and severity of PN between the initial BTZ regimen and upon retreatment. Furthermore, this study evaluated how certain factors affect BIPN, which will help determine what conditions should be considered prior to retreatment. Charts were reviewed from 93 patients who were retreated with a BTZ-containing regimen after previously being treated with this drug. Among the patients who developed PN, most patients in the study had low-grade neuropathy during the initial BTZ treatment (n = 52, 68%). The results showed no evidence of cumulative toxicity, and there was no significant difference in the incidence and severity of PN upon retreatment. Factors such as the presence of baseline PN, number of prior treatments, dose of BTZ, and comorbidities did not increase the severity of PN upon retreatment. The lapse of time between the two regimens also did not affect the severity of PN. The results suggest that retreatment with BTZ may be a feasible option, without additional risks of PN, for MM patients even with peripheral neuropathy during their initial treatment with this drug.

    Upper arm deformities secondary to weight loss or senile elastosis have led to an increased demand for aesthetic contouring procedures. We conducted this study to objectively assess if, in Teimourian low-grade upper arm remodelling, one session of laser-assisted lypolisis (LAL) could result in full patient satisfaction. Between 2011 and 2013, 45 patients were treated for unsightly fat arm Teimourian grade I (15 patients), grade IIa (15 patients) and grade IIb (15 patients) with one session of LAL. The laser used in this study was a 1470-nm diode laser (Alma Lasers, Cesarea, Israel) with the following parameters: continuous mode, 15 W power and transmission through a 600-μm optical fibre. Previous mathematical modelling suggested that 0.1 kJ was required in order to destroy 1 ml of fat. Treatment parameters and adverse effects were recorded.The arm circumference and skin pinch measurements were assessed pre and postoperatively. Patients were asked to file a satisfaction questionnaire. Pain during the anaesthesia and discomfort after the procedure were minimal. Complications included prolonged oedema in 11 patients. The average arm circumference decreased by 4.9 ± 0.4 cm in the right arm (p < 0.01) and 4.7 ± 0.5 cm in the left arm (p < 0.01) in grade I patients, 5.5 ± 0.6 cm in the right arm (p < 0.01) and 5.2 ± 0.5 cm in the left arm (p < 0.01) in grade IIa patients and 5.4 ± 0.5 cm in the right arm (p < 0.01) and 5.3 ± 0.5 cm in the left arm (p < 0.01) in grade IIB patients. The skin tightening effect was confirmed by the reduction of the skin calliper measurements in all three groups. Overall mean opinion of treatment was high for both patients and investigators. Of the 45 patients, all but one would recommend this treatment. A single session of LAL in upper arm remodelling for Teimourian grades I to IIb is a safe and reproducible technique. The procedure allows reduction in the amount of adipose deposits

    The pilot phase IIb VIKING study suggested that dolutegravir (DTG), a human immunodeficiency virus (HIV) integrase inhibitor (INI), would be efficacious in INI-resistant patients at the 50 mg twice daily (BID) dose. VIKING-3 is a single-arm, open-label phase III study in which therapy-experienced adults with INI-resistant virus received DTG 50 mg BID while continuing their failing regimen (without raltegravir or elvitegravir) through day 7, after which the regimen was optimized with ≥1 fully active drug and DTG continued. The primary efficacy endpoints were the mean change from baseline in plasma HIV-1 RNA at day 8 and the proportion of subjects with HIV-1 RNA <50 c/mL at week 24. Mean change in HIV-1 RNA at day 8 was -1.43 log10 c/mL, and 69% of subjects achieved <50 c/mL at week 24. Multivariate analyses demonstrated a strong association between baseline DTG susceptibility and response. Response was most reduced in subjects with Q148 + ≥2 resistance-associated mutations. DTG 50 mg BID had a low (3%) discontinuation rate due to adverse events, similar to INI-naive subjects receiving DTG 50 mg once daily. DTG 50 mg BID-based therapy was effective in this highly treatment-experienced population with INI-resistant virus. www.clinicaltrials.gov (NCT01328041) and http://www.gsk-clinicalstudywww.gsk-clinicalstudyregister.com (112574). © The Author 2014.

    Psychological distress is a well-known complication in rheumatoid arthritis (RA), but knowledge regarding emotions and their relationship to participation restrictions is scarce. The objective of the study was to explore emotions related to participation restrictions by patients with early RA. In this study, 48 patients with early RA, aged 20-63 years, were interviewed about participation restrictions using the critical incident technique. Information from transcribed interviews was converted into dilemmas and linked to International Classification of Functioning, Disability, and Health (ICF) participation codes. The emotions described were condensed and categorized. Hopelessness and sadness were described when trying to perform daily activities such as getting up in the mornings and getting dressed, or not being able to perform duties at work. Sadness was experienced in relation to not being able to continue leisure activities or care for children. Examples of fear descriptions were found in relation to deteriorating health and fumble fear, which made the individual withdraw from activities as a result of mistrusting the body. Anger and irritation were described in relation to domestic and employed work but also in social relations where the individual felt unable to continue valued activities. Shame or embarrassment was described when participation restrictions became visible in public. Feelings of grief, aggressiveness, fear, and shame are emotions closely related to participation restrictions in everyday life in early RA. Emotions related to disability need to be addressed both in clinical settings in order to optimize rehabilitative multi-professional interventions and in research to achieve further knowledge.

In total, 35 patients (71% were grade 4, and 14 (29% were grade 5. A total of 42 (85% patients had one aneurysm, 6 (12% had two aneurysms, and 1 (3% had three aneurysms. Out of 49 patients, one technical (2% and one clinical (2% complication occurred at surgery. Twenty-one (43% patients recovered well, including 7 with postoperative hematoma requiring an immediate evacuation of a clot. Fourteen (29% patients had hydrocephalus and required a ventriculo-peritoneal shunt; 12 patients underwent tracheotomy postoperatively due to coma and pulmonary infection. We found that patients with Hunt and Hess grade 4 and 5 aneurysms can undergo successful neurosurgical clipping of the aneurysms after SAH. However, the morbidity and mortality rates remain high because of their poor clinical condition and a high incidence of vasospasm during treatment.

    Conclusion: Surgery for lung cancer on patients with Grade 2 radiation pneumonitis should be deferred until the patients complete steroid therapy, and the clinical pneumonitis is cured. Moreover, it is believed that it is important to remove the resolved radiation pneumonitis without leaving any residual areas and not to cut into any areas of active radiation pneumonitis as much as possible.

    The Big Data era in Biomedical research has resulted in large-cohort data repositories such as The Cancer Genome Atlas (TCGA). These repositories routinely contain hundreds of matched patient samples for genomic, proteomic, imaging, and clinical data modalities, enabling holistic and multi-modal integrative analysis of human disease. Using TCGA renal and ovarian cancer data, we conducted a novel investigation of multi-modal data integration by combining histopathological image and RNA-seq data. We compared the performances of two integrative prediction methods: majority vote and stacked generalization. Results indicate that integration of multiple data modalities improves prediction of cancer grade and outcome. Specifically, stacked generalization, a method that integrates multiple data modalities to produce a single prediction result, outperforms both single-data-modality prediction and majority vote. Moreover, stacked generalization reveals the contribution of each data modality (and specific features within each data modality) to the final prediction result and may provide biological insights to explain prediction performance.

    We investigated the androgen receptor (AR) gene mutation profiles of Chinese patients exhibiting severe androgen insensitivity syndrome (AIS) phenotypes. The present study enrolled 28 patients with genetically diagnosed AIS, who presented with severe phenotypes (Prader grade 0-3). Patients and some family members were screened via amplification and sequencing of their AR exons 1-8, including the corresponding intronic flanking regions. Luteinizing (LH), follicle-stimulating (FSH), and testosterone (T) hormone levels were found to be slightly, but not significantly, higher in patients with complete androgen insensitivity syndrome (CAIS) than in patients with partial androgen insensitivity syndrome (PAIS) (P>0.05). We identified 24 different AR mutations, including 12 that were novel. Ten patients (cases 2, 3, 10, 28, 11, 12, 19, 20, 24, and 25) were found to carry five recurrent mutations (p.Y572S, p.P914S, p.S176R, p.Y782N, and p.R841H); of these, p.Y572S, p.S176R, and p.Y782N were novel. Among the mutations identified in patients with CAIS, six (66.7%) were characterized as single-nucleotide missense mutations, and six (66.7%) were found to be located in the AR ligand-binding domain (LBD). Among the mutations identified in patients with PAIS, 15 (93.8%) were found to be missense, and 11 (68.8%) were found to be located in the LBD. Patients 10 and 28 were determined to harbor the same missense mutation (p.P914S), but were diagnosed with CAIS and PAIS, respectively. Sex hormone levels were slightly, but not significantly, elevated in patients with CAIS compared to those with PAIS. Missense mutations spanning AR exons 1-8 were the predominant form of identified mutations, and these were mostly located in the AR LBD. Approximately 50% of the identified mutations were novel, and have enriched the AR gene-mutation database. Patients harboring identical mutations were in some instances found to exhibit divergent phenotypes.

    Objective: To observe the conception status of patients with fallopian tube dysfunction after medical treatment and to guide treatment strategy for patients with different degrees of tubal injury by radionuclide imaging. Methods Six hundred and two patients with at least one side of patent fallopian tube underwent modified fallopian tube radionuclide imaging. The patients were graded as: mild, moderate or severe injury, non-functioning or tubal obstruction. The conception status was analyzed after medical treatment, including abdominal hot pack with Chinese medicine, oral intake of Guizhi tuckahoe capsules,and Kangfu anti-inflammatory anal suppository. The constituent ratios of conception in different groups were compared using χ 2 test and the curative and effective rates were calculated. Results: After 1-6 cycles of medical treatment,patients with fallopian tube dysfunction had a curative rate of 29.5% (46/156) and effective rate of 71.8% (112/156). There was a statistically significant difference among the different degrees of oviduct injury (χ 2 =166.4, P<0.05). After medical treatment,the natural pregnancy rate for patients with bilateral mild, moderate and severe injury was 52.6% (102/194), 42.6% (46/108) and 13.8% (16/116), respectively. The rate for patients with one side of normal tubal function was 78.3% (144/184), which was significantly higher than that of patients with bilateral mild, moderate and severe injury (χ 2 =37.86, 52.09 and 121.71, all P<0.05). The natural pregnancy rates of both mild and moderate injury groups were significantly different from the severe injury group (χ 2 =67.29, 42.82, both P<0.05), but there was no difference between the mild and moderate injury groups (χ 2 =3.29, P>0.05). In the severe injury group, 32.8% (38/116) patients were naturally infertile after the medical treatment, while 53.4% (62/116) patients underwent in vitro fertilization (IVF) and 51.6% (32/62) of them succeeded in pregnancy. Conclusions: The natural

    We proposed a new lymphoscintigrpahic functional grade (LGr) system in extremity lymphedema, and investigated the association between the LGr and a long-term response to physical therapy in patients with extremity lymphedema of stage I. The subjects were 20 patients with unilateral extremity lymphedema of stage I, who underwent pre-treatment extremity lymphoscintigraphy using Tc-99m antimony sulfur colloid, and were treated by complex decongestive physical therapy (CDPT). A proposed lymphoscintigrpahic functional grade system consisted of LGr 0 to LGr 4 according to the ilioinguinal nodal uptake, amount of dermal backflow, and uptake pattern of main and collateral lymphatics : LGr 0 = normal, LGr 1 = decreased lymphatic function without dermal backflow, LGr 2 = decreased lymphatic function with dermal backflow, LGr 3 = non - visualization of main lymphatics with dermal backflow, and LGr 4 = no significant lymphatic transport from injection site. LGr 2 was divided into 2A and 2B based on the amount of dermal backflow. A physician who is a lymphedema specialist determined the long-term outcome to CDPT with normalized response (NR), good response (GR) and poor response (PR) based on the change of edema volume reduction, skin status and occurrence of dermatolymphangioadenitis after the clinical follow-up for more than 1 year. Therapeutic responses were NR in 2 patients. GR in 9 patients and PR in 9 patients. Baseline LGrs were 1 in 7 patients, 2A in 4 patients, 2B in 5 patients, 3 in 2 patients, and 4 in 2 patients. There was a significant relationship between therapeutic response and LGr (p=0.003). In other words, 10 of 11 patients (91%) with LGr 1 or 2A showed NR. or GR. On the contrary, 8 of 9 patients (89%) with LGr 2B, 3 or 4 showed PR. Patients with unilateral extremity lymphedema of stage I had different lymphoscintigrpahic functional grades. This grade system may be useful to predict the response to physical therapy in such patients

    Full Text Available To review the current evidence on therapeutic agents for burns pruritus and use the Grading of Recommendations, Assessment, Development and Evaluation (GRADE classification to propose therapeutic protocols for adult and paediatric patients. All published interventions for burns pruritus were analysed by a multidisciplinary panel of burns specialists following the GRADE classification to rate individual agents. Following the collation of results and panel discussion, consensus protocols are presented. Twenty-three studies appraising therapeutic agents in the burns literature were identified. The majority of these studies (16 out of 23 are of an observational nature, making an evidence-based approach to defining optimal therapy not feasible. Our multidisciplinary approach employing the GRADE classification recommends the use of antihistamines (cetirizine and cimetidine and gabapentin as the first-line pharmacological agents for both adult and paediatric patients. Ondansetron and loratadine are the second-line medications in our protocols. We additionally recommend a variety of non-pharmacological adjuncts for the perusal of clinicians in order to maximise symptomatic relief in patients troubled with postburn itch. Most studies in the subject area lack sufficient statistical power to dictate a ′gold standard′ treatment agent for burns itch. We encourage clinicians to employ the GRADE system in order to delineate the most appropriate therapeutic approach for burns pruritus until further research elucidates the most efficacious interventions. This widely adopted classification empowers burns clinicians to tailor therapeutic regimens according to current evidence, patient values, risks and resource considerations in different medical environments.

    Purpose: To determine the effects of sequential versus concurrent administration of cranial radiotherapy and cisplatin/carmustine (BCNU) chemotherapy on survival and toxicity in newly diagnosed high-grade astrocytomas. Methods and Materials: From 1988 to 1996, 101 patients were treated on 2 therapeutic protocols for malignant glioma that used the identical chemotherapy regimen but differed in the timing of cranial radiotherapy. The eligibility criteria for the 2 protocols were identical. In the first protocol (1988-1991, 52 patients), cisplatin 120 mg/BCNU 120 mg i.v. over 72 h, was given for 3 monthly cycles prior to cranial radiotherapy. After a response rate of 42%, with a median survival of 13 months was achieved with this sequential regimen, a successor protocol (1992-1996, 49 patients) was developed in which cranial radiotherapy began concurrently with the start of the identical chemotherapy regimen. Chemotherapy was delayed but not discontinued if prolonged grade III/IV hematologic toxicity was experienced, but protocol therapy was discontinued if disease progression or thromboembolic events occurred. Survival outcome and hematologic toxicity were compared for the patients treated on these protocols. Results: Seventy-seven percent of sequentially-treated patients and 68% of concurrently-treated patients completed all planned therapy. Kaplan-Meier survival was similar to concurrent or sequential administration of chemotherapy and radiotherapy (median 12.8 months vs. 13.8 months, respectively). Hematologic toxicity was significantly less in sequentially- versus concurrently-treated patients, with median nadir per cycle (2.9 vs. 1.8 x 10 3 /mm 3 ) (p < 0.001), and incidence of grade 3/4 leukopenia 40% versus 77% (p = 0.002). There was also an increase in platelet transfusion requirements in concurrently-treated patients, but no significant worsening of anemia. We postulate that the worsened leukopenia results from the effects of concurrent radiotherapy on

    Treatment with bevacizumab is standard of care for recurrent high-grade gliomas; however, monitoring response to treatment following bevacizumab remains a challenge. The purpose of this study was to determine whether quantifying the sharpness of the fluid-attenuated inversion recovery hyperintense border using a measure derived from texture analysis-edge contrast-improves the evaluation of response to bevacizumab in patients with high-grade gliomas. MRIs were evaluated in 33 patients with high-grade gliomas before and after the initiation of bevacizumab. Volumes of interest within the FLAIR hyperintense region were segmented. Edge contrast magnitude for each VOI was extracted using gradients of the 3D FLAIR images. Cox proportional hazards models were generated to determine the relationship between edge contrast and progression-free survival/overall survival using age and the extent of surgical resection as covariates. After bevacizumab, lower edge contrast of the FLAIR hyperintense region was associated with poorer progression-free survival ( P = .009) and overall survival ( P = .022) among patients with high-grade gliomas. Kaplan-Meier curves revealed that edge contrast cutoff significantly stratified patients for both progression-free survival (log-rank χ 2 = 8.3, P = .003) and overall survival (log-rank χ 2 = 5.5, P = .019). Texture analysis using edge contrast of the FLAIR hyperintense region may be an important predictive indicator in patients with high-grade gliomas following treatment with bevacizumab. Specifically, low FLAIR edge contrast may partially reflect areas of early tumor infiltration. This study adds to a growing body of literature proposing that quantifying features may be important for determining outcomes in patients with high-grade gliomas. © 2018 by American Journal of Neuroradiology.

    Purpose: The clinical management of meningioma is guided by its grade and biologic behavior. Currently, diagnosis of tumor grade follows surgical resection and histopathologic review. Reliable techniques for pre-operative determination of tumor behavior are needed. We investigated the association between imaging features extracted from preoperative gadolinium-enhanced T1-weighted MRI and meningioma grade. Methods: We retrospectively examined the pre-operative MRI for 139 patients with de novo WHO grade I (63%) and grade II (37%) meningiomas. We investigated the predictive power of ten semantic radiologic features as determined by a neuroradiologist, fifteen radiomic features, and tumor location. Conventional (volume and diameter) imaging features were added for comparison. AUC was computed for continuous and χ 2 for discrete variables. Classification was done using random forest. Performance was evaluated using cross validation (1000 iterations, 75% training and 25% validation). All p-values were adjusted for multiple testing. Results: Significant association was observed between meningioma grade and tumor location (p<0.001) and two semantic features including intra-tumoral heterogeneity (p<0.001) and overt hemorrhage (p=0.01). Conventional (AUC 0.61–0.67) and eleven radiomic (AUC 0.60–0.70) features were significant from random (p<0.05, Noether test). Median AUC values for classification of tumor grade were 0.57, 0.71, 0.72 and 0.77 respectively for conventional, radiomic, location, and semantic features after using random forest. By combining all imaging data (semantic, radiomic, and location), the median AUC was 0.81, which offers superior predicting power to that of conventional imaging descriptors for meningioma as well as radiomic features alone (p<0.05, permutation test). Conclusion: We demonstrate a strong association between radiologic features and meningioma grade. Pre-operative prediction of tumor behavior based on imaging features offers promise

    Background Glioblastoma multiforme (GBM) is a class IV astrocytic tumor, the most malignant of the four groups of World Health Organization (WHO) tumors with astrocytic differentiation. Aim The aim of this study was to estab­lish whether a correlation exists between the Ki-67 index of tumors with astrocytic differentiation, WHO grade, and patient survival. Materials and methods A retrospective non-clinical approach to patient selection was chosen for the aim of the study. A total of 47 patients diagnosed and treated for CNS tumors with astrocytic differentiation in the St. Marina University Hospital, Varna, Bulgaria, from September 2012 to July 2016 were retrospectively included into the study cohort. The cases were tested for their immunohistochemistry (IHC) reaction with Ki-67 after their original Hematoxylin and Eosin and IHC slides were reviewed by a single author and blind coded. The Ki-67 positivity index of the nuclei was estimated after digitalization of the slides and calculated by the ImmunoRatio automated count­ing tool. The individual Ki-67 index and patient survival of each case were statistically compared. Results The histopathological groups, after the blind Ki-67 index automated calculation was carried out, revealed no WHO grade I, two WHO grade II samples, four WHO grade III samples and 41 WHO grade IV cases, and these were included in the analysis. The two samples of WHO grade II astrocytic tumors had a mean Ki-67 index of 25%; however, they comprised tumors with an individual index of 43% and 7%, both individual values with a highly unlikely index for this group. The four samples of WHO grade III had a mean Ki-67 index of 4%, standard deviation ±2.16 (p>0.05), with the lowest index being 1% and the highest one being 6%. Both WHO grade II and III did not include enough samples to allow for a proper statistical analysis of patient survival. The 41 GBM cases had a mean Ki-67 index of 17.34%, standard deviation ±10.79 (p>0

    Purpose To assess the efficacy and safety of trastuzumab plus capecitabine with or without pertuzumab in patients with human epidermal growth factor receptor 2-positive metastatic breast cancer who experienced disease progression during or after trastuzumab-based therapy and received a prior taxane. Patients and Methods Patients were randomly assigned to arm A: trastuzumab 8 mg/kg → 6 mg/kg once every 3 weeks plus capecitabine 1,250 mg/m 2 twice a day (2 weeks on, 1 week off, every 3 weeks); or arm B: pertuzumab 840 mg → 420 mg once every 3 weeks plus trastuzumab at the same dose and schedule as arm A plus capecitabine 1,000 mg/m 2 on the same schedule as arm A. The primary end point was independent review facility-assessed progression-free survival (IRF PFS). Secondary end points included overall survival (OS) and safety. Hierarchical testing procedures were used to control type I error for statistical testing of IRF PFS, OS, and objective response rate. Results Randomly assigned (intent-to-treat) populations were 224 and 228 patients in arms A and B, respectively. Median IRF PFS at 28.6 and 25.3 months' median follow-up was 9.0 v 11.1 months (hazard ratio, 0.82; 95% CI, 0.65 to 1.02; P = .0731) and interim OS was 28.1 v 36.1 months (hazard ratio, 0.68; 95% CI, 0.51 to 0.90). The most common adverse events (all grades; incidence of ≥ 10% in either arm and ≥ 5% difference between arms) were hand-foot syndrome, nausea, and neutropenia in arm A, and diarrhea, rash, and nasopharyngitis in arm B. Conclusion The addition of pertuzumab to trastuzumab and capecitabine did not significantly improve IRF PFS. An 8-month increase in median OS to 36.1 months with pertuzumab was observed. Statistical significance for OS cannot be claimed because of the hierarchical testing of OS after the primary PFS end point; however, the magnitude of OS difference is in keeping with prior experience of pertuzumab in metastatic breast cancer. No new safety signals were identified.

    Full Text Available The transcription factor forkhead box D3 (FOXD3 plays important roles in the development of neural crest and has been shown to suppress the development of various cancers. However, the expression and its potential biological roles of FOXD3 in high-grade gliomas (HGGs remain unknown.The mRNA and protein expression levels of FOXD3 were examined using real-time quantitative PCR and western blotting in 23 HGG and 13 normal brain samples, respectively. Immunohistochemistry was used to validate the expression FOXD3 protein in 184 HGG cases. The association between FOXD3 expression and the prognosis of HGG patients were analyzed using Kaplan-Meier survival curves and Cox proportional hazards regression models. In addition, we further examined the effects of FOXD3 on the proliferation and serum starvation-induced apoptosis of glioma cells.In comparison to normal brain tissues, FOXD3 expression was significantly decreased in HGG tissues at both mRNA and protein levels. Immunohistochemistry further validated the expression of FOXD3 in HGG tissues. Moreover, low FOXD3 expression was significantly associated with poor prognosis in HGG patients. Depletion of FOXD3 expression promoted glioma cell proliferation and inhibited serum starvation-induced apoptosis, whereas overexpression of FOXD3 inhibited glioma cell proliferation and promoted serum starvation-induced apoptosis.Our results indicated that FOXD3 might serve as an independent prognostic biomarker and a potential therapeutic target for HGGs, which warrant further investigation.

    The aim of this study was to determine the esophageal transit time in control individuals and in chagasic patients with or without megaesophagus.A total of 148 patients were allocated in 6 groups according to serological diagnostic of Chagas disease and the degree of esophageal dilatation: A, control healthy individuals (n = 34, 22.9%); B, indeterminate form (n = 23, 15.5%); C, megaesophagus I (n = 37, 25.0%); D, megaesophagus II (n = 19, 12.8%); E, megaesophagus III (n = 21, 14.2%); and F, megaesophagus IV (n = 14, 9.5%). After 8-hour fasting, patients were asked to swallow 75 mL of barium sulfate solution. x-Rays were obtained after 8, 30, 60, and 90 seconds, 5, 10, 30, 60, and 90 minutes, 2, 6, 12, 24 hours, and at every 12 hours until no more contrast was seen in the esophagus. This was the transit time.The transit time varied from 8 seconds to 36 hours (median = 90 seconds). A linear correlation was observed between transit time and megaesophagus grade: 8 seconds in groups A and B, 5 minutes in C, 30 minutes in D, 2 hours in E, and 9:15 hours in F. Dysphagia was not reported by 60 of 114 (52.6%) patients with positive serological tests for Chagas disease (37/91-40.7%-of patients with megaesophagus I-IV grades). The esophageal transit time increased with the grade of megaesophagus.The esophageal transit time has a direct correlation with the grade of megaesophagus; dysphagia complaint correlates with the grade of megaesophagus. However, many patients with megaesophagus do not report dysphagia.

    Full Text Available Objective: to estimate the antihypertensive, antiremodelling efficacy and clinical tolerability of the monotherapy with Zofenopril in patients with Grade 1 and 2 hypertension (HT 1 and 2 Materials and Methods: The study included 30 patients aged from 30 to 60 years with HT 1 and 2 (ESH/ESC, 2013 without severe comorbidities and cardiovascular complications. Zofenopril was prescribed as monotherapy to HT patients who had never been treated before or patients after one week of lavage from previous antihypertensive therapy, who did not reach target levels of BP. Before and during treatment all patients were checked on office BP using Korotkov’s method and ambulatory blood pressure monitoring (ABPM. Echocardiography and Doppler sonography were carried out by standard methods using the recommendations of the American Society of Echocardiography. Intima-media thickness (IMT of the carotid artery and brachial artery was measured by a 7.5MHz high-resolution ultrasound. Assessment of flow-mediated dilation (FMD of the brachial artery was used as a method of determining endothelial function. Results: A 12-week monotherapy with Zofenopril in average daily dose of 36.0±19.54 mg showed a high antihypertensive efficacy and a good safety profile without side effects. We noted a reliable decrease in systolic BP (SBP, diastolic BP (DBP, mean BP, and pulse pressure (PP by -19.53±5.93%, -18.64±7.18%, BP -19.05±6.14%, and -20.65±12.07%, respectively. Target SBP, DBP, and SBP+DBP were reached in 90%, 86.6%, and 83.3% of patients, respectively. We found a significant regression of LVH, significant improvement in volume indicators of LV echogeometry and parameters of FMD of the brachial artery, as well as a decrease in IMT of carotid and brachial arteries. Monotherapy with Zofenopril showed metabolic neutrality regarding the lipid and carbohydrate metabolism, a good safety profile without the side effects and undesired events.

    Although age is thought to correlate with the prognosis of glioma patients, the most appropriate age-group classification standard to evaluate prognosis had not been fully studied. This study aimed to investigate the influence of age-group classification standards on the prognosis of patients with high-grade hemispheric glioma (HGG). This retrospective study of 125 HGG patients used three different classification standards of age-groups (≤ 50 and >50 years old, ≤ 60 and >60 years old, ≤ 45 and 45-65 and ≥ 65 years old) to evaluate the impact of age on prognosis. The primary end-point was overall survival (OS). The Kaplan-Meier method was applied for univariate analysis and Cox proportional hazards model for multivariate analysis. Univariate analysis showed a significant correlation between OS and all three classification standards of age-groups as well as between OS and pathological grade, gender, location of glioma, and regular chemotherapy and radiotherapy treatment. Multivariate analysis showed that the only independent predictors of OS were classification standard of age-groups ≤ 50 and > 50 years old, pathological grade and regular chemotherapy. In summary, the most appropriate classification standard of age-groups as an independent prognostic factor was ≤ 50 and > 50 years old. Pathological grade and chemotherapy were also independent predictors of OS in post-operative HGG patients. Copyright © 2015. Published by Elsevier B.V.

    The aim of this study was to compare survival before and after 2004 and define the prognostic factors for high-grade osteosarcomas beyond those of typical young patients with localized extremity disease. Few studies have reported the long-term treatment outcomes of high-grade osteosarcoma in Taiwan. A total of 202 patients with primary high-grade osteosarcoma who received primary chemotherapy at Taipei Veterans General Hospital between January 1995 and December 2011 were retrospectively evaluated and compared by period (1995-2003 vs 2004-2011). Patients of all ages and tumor sites and those following or not following controlled protocols were included in analysis of demographic, tumor-related, and treatment-related variables and survival. Overall survival and progression-free survival at 5 years were, respectively, 67.7% and 48% for all patients (n = 202), 77.3% and 57.1% for patients without metastasis (n = 157), and 33.9% and 14.8% for patients with metastasis (n = 45). The survival rates of patients treated after 2004 were significantly higher (by 13%-16%) compared with those of patients treated before 2004, with an accompanying 30% increase in histological good response rate (P = .002). Factors significantly contributing to inferior survival in univariate and multivariate analyses were diagnosis before 2004, metastasis at diagnosis, and being a noncandidate for a controlled treatment protocol. By comparison with the regimens used at our institution before 2004, the current results support the effectiveness of the post-2004 regimens, which consisted of substantially reduced cycles of high-dose methotrexate and a higher dosage of ifosfamide per cycle, cisplatin, and doxorubicin, for treating high-grade osteosarcoma in Asian patients.

    To evaluate a training intervention for general practice-based doctors and nurses in terms of the identification, documentation, and referral of male patients experiencing or perpetrating domestic violence and abuse (DVA) in four general practices in the south west of England. Research suggests that male victims and perpetrators of DVA present to primary care clinicians to seek support for their experiences. We know that the response of primary care clinicians to women patients experiencing DVA improves from training and the establishment of referral pathways to specialist DVA services. The intervention consisted of a 2-h practice-based training. Outcome measures included: a pre-post, self-reported survey of staff practice; disclosures of DVA as documented in medical records pre-post (six months) intervention; semi-structured interviews with clinicians; and practice-level contact data collected by DVA specialist agencies. Results show a significant increase in clinicians' self-reported preparedness to meet the needs of male patients experiencing or perpetrating DVA. There was a small increase in male patients identified within the medical records (6 pre- to 17 post-intervention) but only five of those patients made contact with a specialist DVA agency identified within the referral pathway. The training increased clinicians' confidence in responding to male patients affected by DVA. The increase in recorded identification of DVA male patients experiencing or perpetrating DVA was small and contact of those patients with a specialist DVA support service was negligible. We need to better understand male help seeking in relation to DVA, further develop interventions to increase identification of male patients experiencing or perpetrating DVA behaviours, and facilitate access to support services.

    This study enrolled 64 patients with bladder cancer disease, 54 of them treated by surgery and 10 by radiotherapy. The patients were classified according to their clinical data that include infection with bilharziasis, grade, stage and type of tumor. The present study included determination of telomerase activity in tissue and urine using molecular methods and the levels of nuclear matrix protein 22 (NMP22) and fibronectin in urine. The applied tumor markers showed significant differences in malignant patients compared to control. The same picture was noticed in case of patients received radiotherapy but less pronounced. The results revealed that there is significant correlation between the three tumor markers and the grade of tumor, while NMP22 and fibronectin correlated with stage. Moreover, fibronectin only have significant correlation with the infection with the bilharziasis. The results indicated that determination of telomerase, fibronectin and NMP22 can give clear idea about the development of malignancy and may help in the prediction of cancer recurrence

    For patients with high-grade glioma on clinical trials it is important to accurately assess time of disease progression. However, differentiation between pseudoprogression (PsP) and progressive disease (PD) is unreliable with standard magnetic resonance imaging (MRI) techniques. Dynamic susceptibility contrast perfusion MRI (DSC-MRI) can measure relative cerebral blood volume (rCBV) and may help distinguish PsP from PD. A subset of patients with high-grade glioma on a phase II clinical trial with temozolomide, paclitaxel poliglumex, and concurrent radiation were assessed. Nine patients (3 grade III, 6 grade IV), with a total of 19 enhancing lesions demonstrating progressive enhancement (≥25% increase from nadir) on postchemoradiation conventional contrast-enhanced MRI, had serial DSC-MRI. Mean leakage-corrected rCBV within enhancing lesions was computed for all postchemoradiation time points. Of the 19 progressively enhancing lesions, 10 were classified as PsP and 9 as PD by biopsy/surgery or serial enhancement patterns during interval follow-up MRI. Mean rCBV at initial progressive enhancement did not differ significantly between PsP and PD (2.35 vs. 2.17; P=0.67). However, change in rCBV at first subsequent follow-up (-0.84 vs. 0.84; P=0.001) and the overall linear trend in rCBV after initial progressive enhancement (negative vs. positive slope; P=0.04) differed significantly between PsP and PD. Longitudinal trends in rCBV may be more useful than absolute rCBV in distinguishing PsP from PD in chemoradiation-treated high-grade gliomas with DSC-MRI. Further studies of DSC-MRI in high-grade glioma as a potential technique for distinguishing PsP from PD are indicated.

    Vascular characteristics of tumour and peritumoral volumes of high-grade gliomas change with treatment. This work evaluates the variations of T2*-weighted perfusion parameters as overall survival (OS) predictors. Forty-five patients with histologically confirmed high-grade astrocytoma (8 grade III and 37 grade IV) were included. All patients underwent pre- and post-treatment T2*-weighted contrast-enhanced magnetic resonance (MR) imaging. Tumour, peritumoral and control volumes were segmented. Relative variations of cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), K{sup trans-T2*}, k{sub ep-T2*}, v{sub e-T2*} and v{sub p-T2*} were calculated. Differences regarding tumour grade and surgical resection extension were evaluated with ANOVA tests. For each parameter, two groups were defined by non-supervised clusterisation. Survival analysis were performed on these groups. For the tumour region, the 90th percentile increase or stagnation of CBV was associated with shorter survival, while a decrease related to longer survival (393 ± 189 vs 594 ± 294 days; log-rank p = 0.019; Cox hazard-ratio, 2.31; 95% confidence interval [CI], 1.12-4.74). K{sup trans-T2*} showed similar results (414 ± 177 vs 553 ± 312 days; log-rank p = 0.037; hazard-ratio, 2.19; 95% CI, 1.03-4.65). The peritumoral area values showed no relationship with OS. Post-treatment variations of the highest CBV and K{sup trans-T2*} values in the tumour volume are predictive factors of OS in patients with high-grade gliomas. (orig.)

    Because the clinical course of low-grade gliomas in the individual adult patient varies considerably and is unpredictable, we investigated the prognostic value of dynamic (18)F-fluorethyltyrosine ((18)F-FET) PET in the early diagnosis of astrocytic low-grade glioma (World Health Organization grade II). Fifty-nine patients with newly diagnosed low-grade glioma and dynamic (18)F-FET PET before histopathologic assessment were retrospectively investigated. (18)F-FET PET analysis comprised a qualitative visual classification of lesions; assessment of the semiquantitative parameters maximal, mean, and total standardized uptake value as ratio to background and biologic tumor volume; and dynamic analysis of intratumoral (18)F-FET uptake over time (increasing vs. decreasing time-activity curves). The correlation between PET parameters and progression-free survival, overall survival, and time to malignant transformation was investigated. (18)F-FET uptake greater than the background level was found in 34 of 59 tumors. Dynamic (18)F-FET uptake analysis was available for 30 of these 34 patients. Increasing and decreasing time-activity curves were found in 18 and 12 patients, respectively. Neither the qualitative factor presence or absence of (18)F-FET uptake nor any of the semiquantitative uptake parameters significantly influenced clinical outcome. In contrast, decreasing time-activity curves in the kinetic analysis were highly prognostic for shorter progression-free survival and time to malignant transformation (P dynamic (18)F-FET PET constitute an unfavorable prognostic factor in astrocytic low-grade glioma and, by identifying high-risk patients, may ease treatment decisions.

    Computed tomography (CT) has become the preferred method for evaluation of the abdomen for victims of blunt trauma. Grading of liver injuries, primarily by CT, has been advocated as a measure of severity and, by implication, the likelihood for intervention or complications. We have sought to determine if grading of liver injuries, as a clinical tool, affects immediate or extended management of patients. We have retrospectively reviewed all patients sustaining blunt liver injuries as diagnosed by CT over a five-year period at a Level I trauma center to determine if grading of injury influenced management. The AAST organ scaling system was utilized (major grade 4-5, minor grade 1-3), as well as the ISS, AIS, mortality, morbidity, and treatment. There were 133 patients available for review. The patients were grouped into major (n = 20) and minor (n = 113) liver injuries and operative (n = 12) and nonoperative (n = 121) management. Major liver injuries had a higher ISS (39 + 13 vs. 27 + 15, p = 0.001) and were more likely to require operative intervention (5/20 vs. 7/113, p = 0.02). Mortality in this group was not different (major vs. minor), and there were no differences in the incidence of complications. Twelve patients (9%) required operation, all for hemodynamic instability, all within 24 h, and 11/12 within 6 h. At operation 8/12 patients had other sources of bleeding beside the liver injury, and 7/12 had minor hepatic injuries. The operative patients had higher ISS and AIS scores (head/neck, chest, abdomen, extremities) than those managed nonoperatively. More patients died in the operative group (6/12 vs. 8/121, p = 0.0003). There were more pulmonary (6/12 vs. 16/121, p = 0.005), cardiovascular (6/12 vs. 19/121, p = 0.01), and infectious (5/12 vs. 20/121, p = 0.049) complications in the operative group. There were 14 deaths overall; 13/14 were due to traumatic brain injury, and 8/14 required urgent operation for hemorrhage. In conclusion, grading of liver

    To evaluate the relationship between the waveform of the right hepatic vein and the histological grade and stage in patients with chronic hepatitis B. Eighty-seven patients with chronic hepatitis B were examined prospectively by one sonographer. In each patient, Doppler waveform of the right hepatic vein was obtained. Doppler waveform was classified into 3 type, type 0; normal triphasic pattern, type 1; reduced amplitude of phasic oscillation and no reverse flow phase, and type 2; completely flat flow pattern. In the same session, an ultrasound guided liver biopsy was performed and submitted to one pathologist for grading and staging. Duplex doppler ultrasonography of the right hepatic vein was also performed in 12 control subjects with no evidence of liver or heart disease. The doppler waveform was compared with the histologic severity and a statistical analysis was performed. In the control group, all cases had type 0 waveform. In the hepatitis group, there were type 0 waveform in 61 cases (70.1%), type 1 waveform in 22 cases (25.3%) and type 2 waveform in 4 cases (4.6%). The frequency of abnormal waveform is significantly higher in patients with grade 3-4 and stage 3-4 than grade and stage 1-2 (p>0.005). In the hepatitis group, the venous pulsatility index (VPI) was 0.17-0.69 (mean 0.41), and decreased in the highest and mean values when increasing the histologic scores. However, it was nor significant statistically (p>0.05). The frequency of abnormal waveform was correlated with the histologic severity in patients with chronic hepatitis B. The highest and mean values of the VPI were also correlated. However 70.1% of the patients with chronic hepatitis B showed normal waveform. So doppler ultrasonogram of the hepatic vein may be useful for the diagnosis and the differential diagnosis from cirrhosis in patients with chronic hepatitis B by combination of doppler waveform and venous pulsatility index.

    Objectives: We conducted an analysis of correlation between histological grading of chronic gastritis and the presence of H. pylori infection to investigate if H. pylori influences histological severity of chronic gastritis in Korean patients with peptic ulcers. Methods: Gastroscopic antral biopsy specimens and peripheral venous blood were taken from 80 patients with gastric or duodenal ulcers. H. pylori was identified microscopically in sections with Giemsa staining and quantitative grading of cultured H. pylori was reported on a scale 0 to 3. The histopathological features of biopsy specimens were reported according to the Sydney classification of chronic gastritis. Serum gastritis and pepsinogen concentrations were measured by radioimmunoassay. Results: H. pylori was identified in 62.5% (20 of 32 GU, 30 of 48 DU) of the study group. Gastric clonization rate of H. pylori did not increased with age. Forty of 50 biopsy specimens with H. pylori and also 23 of 30 biopsy specimens without H. pylori showed active chronic gastritis. There was no significant correlation overall between the presence of H. pylori and histological grading of chronic gastritis, including activity, and also no association was found between the quantitative grading of H. pylori and the histological grading of chronic gastritis. With and without H. pylori, a mean of serum gastritis concentration (79.4±43.0 pg/ml and 80.2±31.9 pg/ml) showed no significant difference, but a mean of serum pepsinogen concentration (87.7±41.6 ng/ml and 119±34.4 ng/ml) showed significant difference between the populations with and without H. pylori (p=0.001) Conclusions: The influence of H. pylori on histological grading of chronic gastritis in Korean is less than that in prior studies of Western countries, and further investigation of pathogenesis of H. pylori in chronic gastritis and peptic ulceration is necessary.

    To evaluate the prevalence of histological high-grade lesions and cervical cancer in patients with ASCUS cytology. This is a cross-sectional prospective study involving 703 women with a uterus and atypical squamous cells of undetermined significance (ASCUS). The patients were submitted to a colposcopy and underwent a guided biopsy when changes on the colposcopy were detected. The findings revealed 456 (64.9%) women with a normal colposcopy and 247 (35.1%) with colposcopic abnormalities. The biopsy results were: cervical intraepithelial neoplasia grade 1 (CIN 1) in 51 (20.6%) patients, CIN 2 in 11 (4.5%) patients, CIN 3 in 8 (3.2%) patients, and a negative result in 177 (71.7%) patients; no cases of cancer were detected. Tallying of 456 normal colposcopies and 177 negative biopsies yielded a total of 90.04% negative exams. Furthermore, around 7.2% (51/703) of the patients exhibited CIN 1, a lesion associated with a high potential for regression. The biopsy results were not associated with patient age or menopausal status. We conclude that cytological surveillance of patients with ASCUS is feasible and safe given the low risk of CIN 2/3 or cervical cancer. © 2016 S. Karger AG, Basel.

    Purpose/Objective(s): Angiogenic blockade with irradiation may enhance the therapeutic ratio of radiation therapy (RT) through vascular normalization. We sought to determine the safety and toxicity profile of continuous daily-dosed sunitinib when combined with hypofractionated stereotactic RT (fSRT) for recurrent high-grade gliomas (rHGG). Methods and Materials: Eligible patients had malignant high-grade glioma that recurred or progressed after primary surgery and RT. All patients received a minimum of a 10-day course of fSRT, had World Health Organization performance status of 0 to 1, and a life expectancy of >3 months. During fSRT, sunitinib was administered at 37.5 mg daily. The primary endpoint was acute toxicity, and response was assessed via serial magnetic resonance imaging. Results: Eleven patients with rHGG were enrolled. The fSRT doses delivered ranged from 30 to 42 Gy in 2.5- to 3.75-Gy fractions. The median follow-up time was 40 months. Common acute toxicities included hematologic disorders, fatigue, hypertension, and elevated liver transaminases. Sunitinib and fSRT were well tolerated. One grade 4 mucositis toxicity occurred, and no grade 4 or 5 hypertensive events or intracerebral hemorrhages occurred. One patient had a nearly complete response, and 4 patients had stable disease for >9 months. Two patients (18%) remain alive and progression-free >3 years from enrollment. The 6-month progression-free survival was 45%. Conclusions: Sunitinib at a daily dose of 37.5 mg given concurrently with hypofractionated stereotactic reirradiation for rHGG yields acceptable toxicities and an encouraging 6-month progression-free survival

    Many believe that hospital crowding manifesting in the ED with the boarding of admitted patients is a result of significant numbers of acute hospital beds being occupied by patients awaiting discharge to nursing homes, step-down facilities or home with or without additional support. This observational study was performed to establish the actual relationship between boarders in the ED and patients experiencing delayed discharge. Data relating to the number of patients in the ED and their points in their patient pathway were entered into a logbook on a daily basis by the most senior doctor on duty. 630 days of observations of patients boarded in the ED were compared with the number of inpatients with delayed discharges, obtained from the hospital information system, to see if large numbers of inpatients with delayed discharges are associated with crowding in the ED. Two years of data showed an annual ED census of more than 47 000, with a daily mean ED admission rate of 29.85 patients and a daily mean ED boarding figure of 29 patients. A mean of 15.4% of the 823 hospital beds was occupied by patients with delayed discharges, and the hospital ran at, or near, full capacity (99%-105%) all the time. Results obtained highlighted a statistically significant relationship between delayed discharges in the hospital and ED crowding as a result of boarders (p value<0.001, with a regression coefficient of 0.16, 95% CI 0.12 to 0.20). The study also showed that the number of boarders was related to the number of ED admissions in the preceding 24 hours (p=0.036, with a regression coefficient of 0.14, 95% CI 0.05 to 0.28). Delayed hospital discharges significantly contribute to crowding in the ED. Healthcare systems should target timely discharge of inpatients experiencing delayed discharge in an urgent and efficient manner to improve timely access to acute hospital beds for patients requiring emergency admission.

    This paper investigates the relationship between the level of experience of managers and founders, and the likelihood of survival of their new firms. We take advantage of a comprehensive dataset covering the entire Danish labor market from 1980-2000. This is used to trace the activities of top...... ranked members of start-ups prior to their founding, and follow the fate of these firms. More specifically, we compare the survival of spin-offs from surviving parents, spin-offs from exiting parents, and other start-ups. Moreover, we investigate whether firms managed and founded by more experienced....... We also find that spin-offs from parent companies that exit are less likely to survive than either spin-offs from surviving parents or other start-ups. These findings support the theoretical arguments that organizational heritage is important for the survival of new organizations. We found no similar...

    The finding that meningeal solitary fibrous tumors (SFTs) and meningeal hemangiopericytomas (HPCs) are both characterized by NAB2-STAT6 gene fusion has pushed their inclusion in the WHO 2016 Classification of tumors of the central nervous system (CNS) as different manifestations of the same entity. Given that the clinical behavior of the CNS SFT/HPC spectrum ranges from benign to malignant, it is presently unclear whether the grading criteria are still adequate. Here, we present the results of a study that analyzed the prognostic value of an updated version of the Marseille Grading System (MGS) in a retrospectively assembled cohort of 132 primary meningeal SFTs/HPCs with nuclear overexpression of STAT6. The median patient follow-up was 64 months (range 4-274 months); 73 cases (55%) were MGS I, 50 cases (38%) MGS II and 9 cases (7%) were MGS III. Progression-free survival (PFS) and disease-specific survival (DSS) were investigated using univariate analysis: the prognostic factors for PFS included MGS, extent of surgery, radiotherapy, chemotherapy and mitotic activity ≥5/10 high-power field (HPF). Moreover, MGS, radiotherapy, mitotic activity ≥5/10 HPF, and necrosis were the prognostic factors measured for DSS. In multivariate analysis, extent of surgery, mitotic activity ≥5/10 HPF, MGS I and MGS III were the independent prognostic factors measured for PFS while necrosis, MGS III and radiotherapy were the independent prognostic factors for DSS. In conclusion, our results show that assessing the malignancy risk of SFT/HPC should not rely on one single criterion like mitotic activity. Therefore, MGS is useful as it combines the value of different criteria. In particular, the combination of a high mitotic activity and necrosis (MGS III) indicates a particularly poor prognosis. © 2018 International Society of Neuropathology.

    Even though past studies have suggested efficacy of nitrosourea drugs in patients with high-grade glioma and temozolomide has recently been shown significantly to be beneficial, no conclusive comparisons between these agents have been published. We performed a survival gain analysis of 364 studies describing 24,193 patients with high-grade glioma treated in 504 cohorts, and compared the effects of drugs. The most frequent diagnoses were glioblastoma multiforme (GBM) (72%) and anaplastic astrocytoma (22%). The mean overall survival (mOS) was 14.1 months. The outcome was influenced by several of the known prognostic factors including the histological grade, if the tumors were newly diagnosed or recurrent, the completeness of resection, patients' age, and gender. This information allowed the calculation of a predicted mOS for each cohort based on their prognostic factors independent of treatment. Survival gain to characterize the influence of treatment was subsequently defined and validated as the difference between the observed and the predicted mOS. In 62 CCNU-treated cohorts and 15 ACNU-treated cohorts the survival gain was 5.3 months and 8.9 months (P < 0.0005), respectively. No detectable survival gain for patients treated with various BCNU-containing regimens was found. Conclusion CCNU- and ACNU-containing regimens were superior to BCNU containing regiments.

    The albumin-bilirubin (ALBI) score was initially developed for assessing liver dysfunction severity and was suggested to have prognostic value in patients with hepatocellular carcinoma. We aimed to evaluate the prognostic impact of ALBI grade in patients with advanced gastric cancer (GC) after radical gastrectomy. This study included 283 patients who underwent radical gastrectomy for pT2-4 GC without preoperative treatment. ALBI was calculated as follows: (log 10 bilirubin (μmol/L) × 0.66) + (albumin (g/L) × -0.0852) and categorized into grades 1 (≤-2.60), 2 (-2.60<, ≤-1.39) and 3 (-1.39<). The median ALBI score was -2.96, and a number of patients in ALBI grades 1, 2 and 3 were 228, 55 and 0, respectively. Patients with ALBI grade 2 had a lower administration rate of adjuvant chemotherapy than those with ALBI grade 1, whereas no significant differences were found in morbidity rate and disease stage. The ALBI grade 2 group was more likely to have shorter disease-specific and disease-free survival compared with the ALBI grade 1 group. Multivariable analysis identified ALBI grade 2 as an independent prognostic factor for disease-free survival (hazard ratio 1.97, 95% confidence interval 1.10-3.47, p = 0.0242). Survival differences between ALBI grade 1 and 2 groups were increased in the patient subset that received adjuvant chemotherapy. ALBI grade 2 was correlated with a shortened duration of administration of postoperative S-1 adjuvant. ALBI grade serves as a simple and promising predictive factor for disease-free and disease-specific survival in patients with pT2-4 GC after radical gastrectomy.

    This paper describes results to-date from a human pharmacokinetic study which began recruitment in December 2007. Results are presented for a single patient recruited in December 2007. A second patient was recruited in July 2008 but detailed data are not available at the time of writing. The trial is an open-label, non-comparative, non-therapeutic study of BPA-mannitol in patients with high-grade glioma, who will be undergoing stereotactic brain biopsy as part of the diagnostic process before definitive treatment. The study investigates the route of infusion (intra-venous (IV) or intra-carotid artery) and in each case will assess the effect of administration of mannitol as a blood-brain barrier disrupter. All cohorts will receive a 2 h infusion of BPA-mannitol, and for some cohorts an additional mannitol bolus will be administered at the beginning of this infusion. Measurements are made by inductively coupled plasma mass spectrometry (ICP-MS) of {sup 10}B concentration in samples of blood, urine, extra-cellular fluid in normal brain (via a dialysis probe), brain tissue around tumour and tumour tissue. Additional analysis of the tumour tissue is performed using secondary ion mass spectrometry (SIMS). The first patient was part of the cohort having intra-venous infusion without mannitol bolus. No serious clinical problems were experienced and the assay results can be compared with available patient data from other BNCT centres. In particular we note that the peak {sup 10}B concentration in blood was 28.1 mg/ml for a total BPA administration of 350 mg/kg which is very consistent with the previous experience with BPA-fructose reported by the Helsinki group.

    In assigning patients with chronic obstructive pulmonary disease (COPD) to subgroups according to the updated guidelines of the Global Initiative for Chronic Obstructive Lung Disease, discrepancies have been noted between the COPD assessment test (CAT) criteria and modified Medical Research Council (mMRC) criteria. We investigated the determinants of symptom and risk groups and sought to identify a better CAT criterion. This retrospective study included COPD patients seen between June 20, 2012, and December 5, 2012. The CAT score that can accurately predict an mMRC grade ≥ 2 versus COPD patients, the percentages of patients classified into subgroups A, B, C, and D were 24.5%, 47.2%, 4.2%, and 24.1% based on CAT criteria and 49.3%, 22.4%, 8.9%, and 19.4% based on mMRC criteria, respectively. More than 90% of the patients who met the mMRC criteria for the 'more symptoms group' also met the CAT criteria. AUROC and CART analyses suggested that a CAT score ≥ 15 predicted an mMRC grade ≥ 2 more accurately than the current CAT score criterion. During follow-up, patients with CAT scores of 10 to 14 did not have a different risk of exacerbation versus those with CAT scores COPD patients.

    Full Text Available PURPOSE: The monocyte-to-lymphocyte ratio (MLR has been shown to be associated with the prognosis of various solid tumors. This study sought to evaluate the important value of the MLR in ovarian cancer patients. METHODS: A total of 133 ovarian cancer patients and 43 normal controls were retrospectively reviewed. The patients' demographics were analyzed along with clinical and pathologic data. The counts of peripheral neutrophils, lymphocytes, monocytes, and platelets were collected and used to calculate the MLR, neutrophil-to-lymphocyte ratio (NLR. and platelet-to-lymphocyte ratio (PLR. The optimal cutoff value of the MLR was determined by using receiver operating characteristic curve analysis. We compared the MLR, NLR, and PLR between ovarian cancer and normal control patients and among patients with different stages and different grades, as well as between patients with lymph node metastasis and non–lymph node metastasis. We then investigated the value of the MLR in predicting the stage, grade, and lymph node positivity by using logistic regression. The impact of the MLR on overall survival (OS was calculated by Kaplan-Meier method and compared by log-rank test. RESULTS: Statistically significant differences in the MLR were observed between ovarian cancer patients and normal controls. However, no difference was found for the NLR and PLR. Highly significant differences in the MLR were found among patients with different stages (stage I-II and stage III-IV, grades (G1 and >G1, and lymph node metastasis status. The MLR was a significant and independent risk factor for lymph node metastasis, as determined by logistic regression. The optimal cutoff value of the MLR was 0.23. We also classified the data according to tumor markers (CA125, CA199, HE4, AFP, and CEA and conventional coagulation parameters (International Normalized Ratio [INR] and fibrinogen. Highly significant differences in CA125, CA199, HE4, INR, fibrinogen levels, and lactate

    2015-10-01

    In 2014 a consensus conference convened by the International Society of Urological Pathology (ISUP) adopted amendments to the criteria for Gleason grading and scoring (GS) for prostatic adenocarcinoma. The meeting defined a modified grading system based on 5 grading categories (grade 1, GS 3+3; grade 2, GS 3+4; grade 3, GS 4+3; grade 4, GS 8; grade 5, GS 9-10). In this study we have evaluated the prognostic significance of ISUP grading in 496 patients enrolled in the TROG 03.04 RADAR Trial. There were 19 grade 1, 118 grade 2, 193 grade 3, 88 grade 4 and 79 grade 5 tumours in the series, with follow-up for a minimum of 6.5 years. On follow-up 76 patients experienced distant progression of disease, 171 prostate specific antigen (PSA) progression and 39 prostate cancer deaths. In contrast to the 2005 modified Gleason system (MGS), the hazards of the distant and PSA progression endpoints, relative to grade 2, were significantly greater for grades 3, 4 and 5 of the 2014 ISUP grading scheme. Comparison of predictive ability utilising Harrell's concordance index, showed 2014 ISUP grading to significantly out-perform 2005 MGS grading for each of the three clinical endpoints.

    2017-08-01

    Full Text Available Purpose: Smear scores and induration sizes resulting from the PPD (tuberculin purified protein derivative test can serve as indicators of whether a patient suffering from tuberculosis shows smear conversion or not. Methods: Using microbiological methods smear and sputum tests, patients diagnosed as infected with between 2002 and 2015 were included in this study. All of the assumed factors that may have a role in smear conversion were studied, in addition to the prolongation of tuberculosis. Results: 398 of 512 patients fulfilled all the inclusion criteria and formed the basis of this study. 215 patients (54% were females and 183 (46% were males. The median age for both men and women was 36 years. We found a statistically significant difference between the size of induration resulting from the PPD skin test and the rate of non-conversion (=0.002. Further univariate analysis also showed that smear grading and an induration size of ≥10 mm were independently associated with delayed smear conversion. Patients with cavitary lesions showed a higher rate of non-conversion after two months, which was not significant. We could not find any association between some of the variables, such as age, sex, weight, smoking, alcoholism, addictions, respiratory diseases, diabetes mellitus, alternative anti-TB treatment, and smear conversion. Conclusion: Intensified treatment and precautions against transmission should be especially considered for TB patients with high smear grading and an induration size of more than 10 mm.

    The purpose of this study was to examine advanced diffusion-weighted magnetic resonance imaging (DW-MRI) models for differentiation of low- and high-grade tumors in the diagnosis of pediatric brain neoplasms. Sixty-two pediatric patients with various types and grades of brain tumors were evaluated in a retrospective study. Tumor type and grade were classified using the World Health Organization classification (WHO I-IV) and confirmed by pathological analysis. Patients underwent DW-MRI before treatment. Diffusion-weighted images with 16 b-values (0-3500 s/mm{sup 2}) were acquired. Averaged signal intensity decay within solid tumor regions was fitted using two-compartment and anomalous diffusion models. Intracellular and extracellular diffusion coefficients (D{sub slow} and D{sub fast}), fractional volumes (V{sub slow} and V{sub fast}), generalized diffusion coefficient (D), spatial constant (μ), heterogeneity index (β), and a diffusion index (index{sub d}iff = μ x V{sub slow}/β) were calculated. Multivariate logistic regression models with stepwise model selection algorithm and receiver operating characteristic (ROC) analyses were performed to evaluate the ability of each diffusion parameter to distinguish tumor grade. Among all parameter combinations, D and index{sub d}iff jointly provided the best predictor for tumor grades, where lower D (p = 0.03) and higher index{sub d}iff (p = 0.009) were significantly associated with higher tumor grades. In ROC analyses of differentiating low-grade (I-II) and high-grade (III-IV) tumors, index{sub d}iff provided the highest specificity of 0.97 and D provided the highest sensitivity of 0.96. Multi-parametric diffusion measurements using two-compartment and anomalous diffusion models were found to be significant discriminants of tumor grading in pediatric brain neoplasms. (orig.)

    Background In a majority of cases, whiplash injuries are a domain of conservative therapy. Nevertheless it remains unclear whether physical therapy is of medical or economic benefit in patients with whiplash injuries. Methods Seventy patients with acute Quebec Task Force (QTF) grade II whiplash injuries were randomized to two therapy groups and received either active (APT) or passive (PPT) physical therapy. Patients were compared with regard to pain and range of motion with data obtained in an earlier study from a group with grade II whiplash injuries in which the therapy recommendation had been "act as usual" (AAU; n = 20). The above-mentioned parameters were assessed at 24 hours and two months after the injury. Furthermore patients' period of disability was documented after two months. Results After two months, patients in both the APT and PPT groups showed significant improvement in the median period of disability (active: 14 days; passive: 14 days) compared to the AAU group (49 days). No group difference was observed with regard to median improvement in range of motion (active: 120°; passive: 108°; activity as usual: 70°). The median pain reduction was significantly greater in the APT group (50.5) than in the PPT (39.2) or AAU group (28.8). Conclusion Our data show that active physical therapy results in enhanced pain reduction and shortening of post-injury disability. Therefore, active physical therapy should be considered the treatment of choice in patients with QTF grade II whiplash injuries. Trial registration The study complied with applicable German law and with the principles of the Helsinki Declaration and was approved by the institutional ethics commission. PMID:19149880

    The Neuropathic Pain Special Interest Group (NeuPSIG) of the International Association for the Study of Pain has proposed a grading system for the presence of neuropathic pain (NeP) using the following categories: no NeP, possible, probable, or definite NeP. To further evaluate this system, we investigated patients with neck/upper limb pain with a suspected nerve lesion, to explore: (i) the clinical application of this grading system; (ii) the suitability of 2 NeP questionnaires (Leeds Assessment of Neuropathic Symptoms and Signs pain scale [LANSS] and the painDETECT questionnaire [PD-Q]) in identifying NeP in this patient cohort; and (iii) the level of agreement in identifying NeP between the NeuPSIG classification system and 2 NeP questionnaires. Patients (n = 152; age 52 ± 12 years; 53% male) completed the PD-Q and LANSS questionnaire and underwent a comprehensive clinical examination. The NeuPSIG grading system proved feasible for application in this patient cohort, although it required considerable time and expertise. Both questionnaires failed to identify a large number of patients with clinically classified definite NeP (LANSS sensitivity 22%, specificity 88%; PD-Q sensitivity 64%, specificity 62%). These lowered sensitivity scores contrast with those from the original PD-Q and LANSS validation studies and may reflect differences in the clinical characteristics of the study populations. The diagnostic accuracy of LANSS and PD-Q for the identification of NeP in patients with neck/upper limb pain appears limited. Copyright © 2013 International Association for the Study of Pain.

    Purpose: To assess the rate of serious (>Grade 2, CTCAE 3.0) dermatitis in our head-and-neck cancer (HNC) patients undergoing simultaneous integrated boost intensity-modulated radiotherapy with concomitant cetuximab (SIB-IMRT-cetuximab). We hypothesized a positive association between the radiation dose to the skin and the degree of dermatitis in patients receiving cetuximab. Methods and Materials: Between April 2006 and December 2009, 99 HNC patients underwent SIB-IMRT-cetuximab. In 69/99 (70%), systemic treatment consisted of concomitant cetuximab only, whereas 30 (30%) were switched from concomitant cisplatin to concomitant cetuximab. Treatment-related dermatitis was prospectively monitored. Ninety-nine patients treated with four to seven concomitant cycles of cisplatin only served as an internal control group. The radiation dose delivered to the skin was measured and related to dermal reactions. Results: Grade 3/4 dermatitis developed in 34% of the cetuximab cohort, which was substantially higher than in the control cohort (3%, p < 0.01). No cases of skin necrosis or other fatal events related to cetuximab have occurred so far. A significantly larger mean skin area was found exposed to high radiation doses in patients with severe cetuximab-related dermatitis, compared with those without (p < 0.01). Conclusion: Concomitant cetuximab resulted in a ∼10-fold increase in the rate of severe transient dermatitis compared with the use of concomitant cisplatin. We found a positive association between the incidence of Grade 3/4 dermatitis and the radiation dose delivered to the skin in patients receiving cetuximab.

    Objective To evaluate the correlation between the Manchester Grading Scale and the American Orthopaedic Foot and Ankle Society (AOFAS) score in patients with a hallux valgus deformity. Subjects and Methods The study sample included 181 feet of 122 patients with hallux valgus and 424 feet of 212 individuals without hallux valgus deformity as the control group. The severity of hallux valgus, utilizing a relative nonmetric scale, the Manchester Grading Scale, and the metric AOFAS score, was determined for all individuals in the hallux valgus and control groups. SPSS version 18 (Chicago, Ill., USA) was used for data analysis. Results According to the Manchester Grading Scale, the 424 feet of the normal group were classified as ‘no deformity−. In the hallux valgus group, 85 feet were classified as ‘mild deformity−, 67 as ‘moderate deformity' and 29 as ‘severe deformity−. The AOFAS total score in the control group was 99.14. In the hallux valgus group, patients with mild or moderate deformity had total scores of 86.20 and 68.19, respectively. For those with severe hallux valgus, the total score was 44.69 and the differences were statistically significant (p = 0.000). Using the Pearson correlation, strong negative correlations were found between the AOFAS score and the hallux valgus angle (HVA; r = −0.899, p = 0.000). Strong negative correlations were demonstrated between the AOFAS score and the first intermetatarsal angle (IMA) as well (r = −0.748, p = 0.000). Conclusions The AOFAS score was negatively associated with the Manchester Grading Scale, HVA and first IMA. As the severity of hallux valgus increased, the AOFAS score seemed to decrease.

    Full Text Available Objective: To study the prognostic value of neutrophil disorders in a retrospective cohort of high-grade glioma patients receiving definitive concurrent temozolomide and radiation. Materials and methods: Clinical records of consecutive patients treated in our Institution between January 2005 and December 2010 with concurrent temozolomide (75 mg/m2 daily and radiation were collected. The prognostic value of pretreatment neutrophilia on survival, defined as a neutrophil count exceeding 7 G/L, was examined. Results: We identified 164 patients, all treated with concurrent temozolomide-based chemoradiotherapy. Initial surgery was achieved in most (75%, with resection > 90% in 55 patients (34%. Total 151 patients (92% had glioblastoma, and 13 patients (8% had WHO grade III glioma. Eighty-two patients (50% displayed pretreatment neutrophilia. Neutrophilia was not associated with concurrent or adjuvant temodal discontinuation (p > 0.3. The 2-year actuarial overall survival was 45%. Steroid consumption, i.e. 60 mg or more of daily prednisolone, increased pretreatment neutrophil count (p = 0.005. In univariate analysis, neutrophilia was associated with worse overall survival (p = 0.019, as well as age ≥ 65 years (p = 0.009, surgical resection < 90% (p = 0.003 and prednisolone consumption ≥ 60 mg/day (p = 0.016. In multivariate analysis, neutrophilia (p = 0.013, age ≥ 65 (p = 0.001, and surgical tumor resection < 90% (p = 0.010 independently decreased overall survival, while, steroid consumption was not (p = 0.088. Conclusion: In high-grade gliomas treated with concurrent temozolomide and radiation, pretreatment neutrophilia may be a significant prognosis factor for overall survival. In addition with previously available markers, this independent cost-effective biomarker could help identifying patients with worsened prognosis. Keywords: High grade gliomas, Glioblastoma

    Older patients with cancer suffer from chemotherapy-related toxicities more frequently than younger patients. As novel agents are being used more commonly in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL), toxicities of these agents in older patients have not been well studied. Further, impact of these toxicities on outcomes in the elderly is unknown. This study aimed to answer both questions. We reviewed 14 Alliance for Clinical Trials in Oncology trials that enrolled CLL and/or NHL patients between 2004-2014. Toxicity was assessed per the NCI-CTCAE (version 3-5). Probabilities of experiencing grade three or four hematologic and non-hematologic toxicities were modeled as a function of clinical and disease-related factors using logistic regression. 1199 patients (409 age ≥ 65; 790 age four hematologic [odds ratio (OR) 1.70; p = 0.009: 95% CI (1.57-1.84)] and non-hematologic toxicities [OR 1.47; p = 0.022; 95% CI (1.39-1.55)] were increased in older patients with CLL, as well as odds of grade three or four non-hematologic toxicities [OR 1.89; p = 0.017; 95% CI (1.64-2.17)] in older patients with NHL. Grade three or four hematologic toxicities were associated with inferior OS and PFS in older patients with NHL [HR 3.14; p = 0.006; 95% CI (2.25-4.39) for OS and 3.06; p = 0.011; 95% CI (2.10-4.45) for PFS], though not in CLL. A prognostic model predicting grade three or four toxicities was also developed. CLL and NHL patients ≥ 65 year encounter more toxicities than younger patients even when treated with novel biologic agents. Development of grade three or four hematologic toxicities lead to inferior PFS and OS in NHL but not in CLL. Copyright © 2018 Elsevier Inc. All rights reserved.

    Purpose. A retrospective study of prognostic factors and treatment outcome of osteosarcoma (OS) during modern chemotherapy era with focus on patients with primary metastatic disease, nonextremity localisation, or age >40 years (nonclassical OS). Methods. A nationwide cohort, comprising 424 high-grade Norwegian bone OS patients, was based on registry sources supplemented with clinical records from hospitals involved in sarcoma management between 1975 and 2009. Results. Only 48% were younger patients with tumour in the extremities and without metastasis at diagnosis (classical OS). A considerable discrepancy in survival between classical and nonclassical OS was observed: 61% versus 26% 10-year sarcoma specific survival. Twice as many of the former received both adequate surgery and chemotherapy compared to the latter. This could only partly explain the differences in survival due to inherent chemoresistance in primary metastatic disease and a higher rate of local relapse among patients with axial tumours. Metastasis at diagnosis, increased lactate dehydrogenase, age > 40 years, and tumour size above median value were all adverse prognostic factors for overall survival. Conclusion. We confirm a dramatic difference in outcome between classical and nonclassical high-grade OS patients, but treatment variables could only partly explain the dismal outcome of the latter.

    The purpose of the present study is to analyze the expression of matrix metalloproteinase-3 (MMP-3), magnetic resonance imaging (MRI) grading and histopathological alterations of the intervertebral disc (IVD) for correlations with each other and with the age, gender and low back pain duration of the patients who had undergone operations for lumbar disc herniation (LDH). Forty-two patients were admitted to our clinic with signs of LDH and underwent surgery for LDH at 48 IVD levels. In all cases, specimens for histological and immunohistochemical analyses were removed from the IVD space. Lumbar IVD degeneration on MRI of the 48 IVDs from which surgical specimens had been obtained was classified into five grades using the Pfirrmann classification. In the degenerated IVD, the expression of MMP-3, MRI grading and histopathological alterations of the IVD displayed significant correlation. Increased age is closely related with aforementioned alterations. There was no correlation between MMP-3 expression and age, gender and duration of the pain. For evaluating and treating IVD degeneration, MRI is a good and non-invasive diagnostic tool to determine the severity of degeneration. MMP-3 may be a therapeutic target of the degenerated IVD.

    The prognostic value of the dynamic contrast-enhanced (DCE) MRI perfusion and its histogram analysis-derived metrics is not well established for high-grade glioma (HGG) patients. The aim of this prospective study was to investigate DCE perfusion transfer coefficient (K{sup trans}), vascular plasma volume fraction (v{sub p}), extracellular volume fraction (v{sub e}), reverse transfer constant (k{sub ep}), and initial area under gadolinium concentration time curve (IAUGC) as predictors of progression-free (PFS) and overall survival (OS) in HGG patients. Sixty-nine patients with suspected anaplastic astrocytoma or glioblastoma underwent preoperative DCE-MRI scans. DCE perfusion whole tumor region histogram parameters, clinical details, and PFS and OS data were obtained. Univariate, multivariate, and Kaplan-Meier survival analyses were conducted. Receiver operating characteristic (ROC) curve analysis was employed to identify perfusion parameters with the best differentiation performance. On univariate analysis, v{sub e} and skewness of v{sub p} had significant negative impacts, while k{sub ep} had significant positive impact on OS (P < 0.05). v{sub e} was also a negative predictor of PFS (P < 0.05). Patients with lower v{sub e} and IAUGC had longer median PFS and OS on Kaplan-Meier analysis (P < 0.05). K{sup trans} and v{sub e} could also differentiate grade III from IV gliomas (area under the curve 0.819 and 0.791, respectively). High v{sub e} is a consistent predictor of worse PFS and OS in HGG glioma patients. v{sub p} skewness and k{sub ep} are also predictive for OS. K{sup trans} and v{sub e} demonstrated the best diagnostic performance for differentiating grade III from IV gliomas. (orig.)

    Stigma is a major social barrier that can restrict access to and willingness to seek psychiatric care. Psychiatric consumers may use secrecy and withdrawal in an attempt to cope with stigma. The purpose of this study was to determine the effects of music therapy on self- and experienced stigma in acute care psychiatric inpatients using a randomized design with wait-list control. Participants (N=83) were randomly assigned by cluster to one of three single-session group-based conditions: music therapy, education, or wait-list control. Participants in the music therapy and education conditions completed only posttests while participants in the wait-list control condition completed only pretests. The music therapy condition was a group songwriting intervention wherein participants composed lyrics for "the stigma blues." Results indicated significant differences in measures of discrimination (experienced stigma), disclosure (self-stigma), and total stigma between participants in the music therapy condition and participants in the wait-list control condition. From the results of this randomized controlled investigation, music therapy may be an engaging and effective psychosocial technique to treat stigma. Limitations, suggestions for future research, and implications for clinical practice and psychiatric music therapy research are provided. © 2013.

    The 2014 International Society of Urological Pathology (ISUP) has proposed a new grade group (GG) classification for Gleason scores (GS). The usefulness of the new GG classification was investigated with 518 prostate cancer patients who underwent androgen deprivation therapy. According to the new GG classification, Stages B‒D and the new GG classification relapse-free rate for each stage were calculated using the Kaplan‒Meier method. The new GG classification revealed a significant difference for the relapse-free rate only between some groups. Analysis using the Cox proportional hazards model indicated that the risk of relapse was higher in GGs 4 and 5 than in GG 1. The usefulness about the relapse-free rate in androgen deprivation therapy of the 2014 ISUP new grade group classification a waits future examination.

    Patients with primary immunodeficiency (PID) often receive immunoglobulin replacement therapy (IgRT). Physicians and patients have the choice between various methods of administration. For subcutaneous immunoglobulin infusions, patients may use an automated pump (P) or push the plunger of a syringe (rapid push [RP]). P infusions are performed once a week and last around 1 hour. RP decreases the duration of administration, but requires more frequent infusions. Eight out of 30 patients (coming from a single center) who had participated in the cross-over, randomized, open-label trial comparing P and RP participated in a focus group or underwent in-depth interviews. Patients had a long history of home-based subcutaneous immunoglobulin using P. The trial suggested that RP had slightly greater interference on daily life than P, but similar efficacy and better cost-effectiveness. When asked about the delivery method they had preferred, around one-third of patients pointed out RP rather than P. In-depth interviews may reveal unforeseen reasons for patients' preferences. Interviews underlined the complexity of the relationship that the patients maintain with their disease and IgRT. Even if they recognized the genetic nature of the disease and claimed PID was a part of them, patients tried not to be overwhelmed by the disease. IgRT by P was well integrated in patients' routine. By contrast, RP too frequently reminded the patients of their disease. In addition, some patients pointed out the difficulty of pushing the plunger due to the viscosity of the product. Coming back too frequently, RP was not perceived as time saving over a week. Long-lasting use of P could partly explain patients' reasonable reluctance to change to RP. In-depth interviews of PID patients highlighted unforeseen reasons for patients' preference that the physician needs to explore during the shared medical decision-making process.

    The aim of this study was to provide insight in the use, intensity and toxicity of therapy with capecitabine and oxaliplatin (CAPOX) and capecitabine monotherapy (CapMono) among elderly stage III colon cancer patients treated in everyday clinical practice. Data from the Netherlands Cancer Registry were used. All stage III colon cancer patients aged ≥70 years diagnosed in the southeastern part between 2005 and 2012 and treated with CAPOX or CapMono were included. Differences in completion of all planned cycles, cumulative dosages and toxicity between both regimens were evaluated. One hundred ninety-three patients received CAPOX and 164 patients received CapMono; 33% (n = 63) of the patients receiving CAPOX completed all planned cycles of both agents, whereas 55% (n = 90) of the patients receiving CapMono completed all planned cycles (P characteristics, CapMono was associated with a lower odds of developing grade III-V toxicity than CAPOX (odds ratio 0.54, 95% confidence interval 0.33-0.89). For patients treated with CAPOX, the most common toxicities were gastrointestinal (29%), haematological (14%), neurological (11%) and other toxicity (13%). For patients treated with CapMono, dermatological (17%), gastrointestinal (13%) and other toxicity (11%) were the most common. CAPOX is associated with significantly more grade III-V toxicities than CapMono, which had a pronounced impact on the cumulative dosage received and completion of all planned cycles. In this light, CapMono seems preferable over CAPOX. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Neurosurgery is a challenging field associated with high levels of mental stress. The goal of this study was to investigate the hemodynamic response of experienced neurosurgeons during aneurysm clipping surgery and to evaluate whether neurosurgeons' hemodynamic responses are associated with patients' clinical statuses. Four vascular neurosurgeons (all male; mean age 51 ± 10 years; post-residency experience ≥7 years) were studied during 42 aneurysm clipping procedures. Blood pressure (BP) and heart rate (HR) were assessed at rest and during seven phases of surgery: before the skin incision, after craniotomy, after dural opening, after aneurysm neck dissection, after aneurysm clipping, after dural closure and after skin closure. HR and BP were significantly greater during surgery relative to the rest situation (p ≤ 0.03). There was a statistically significant increase in neurosurgeons' HR (F [6, 41] = 10.88, p neurosurgeon experience, the difference in BP as a function of aneurysm rupture was not significant (p > 0.08). Aneurysm location, intraoperative aneurysm rupture, admission WFNS score, admission Glasgow Coma Scale scores and Fisher grade were not associated with neurosurgeons' intraoperative HR and BP (all p > 0.07). Aneurysm clipping surgery is associated with significant hemodynamic system activation among experienced neurosurgeons. The greatest HR and BP were after aneurysm neck dissection and clipping. Aneurysm location and patient clinical status were not associated with intraoperative changes of neurosurgeons' HR and BP.

The reported findings of orlistat in NAFLD are divisive. Recently, periostin is identified as an important regulatory molecule in the pathogenesis of obesity-induced fatty liver.

A 16-week prospective observational study was conducted, with obese NAFLD patient (n=77 receiving orlistat (120 mg capsules, three times a day with hypocaloric diet or hypocaloric diet only. Grades of fatty liver were determined using ultrasound (US echogenicity of liver; serum levels of periostin, adiponectin, tumor necrosis factor (TNF-α and interleukin-6 were determined using ELISA kits at 0 and 16 weeks. Correlations of US grades of fatty liver with these biomarkers were also determined. Orlistat significantly reversed the US grades of fatty liver (P=0.016, decreased serum levels of periostin (P=0.030 and TNF-α (P=0.040, and increased serum adiponectin levels (P<0.001 when compared with hypocaloric diet only. Serum interleukin-6 levels were not found to be significantly different in both groups after the treatment. In the orlistat group, the degree of reduction in grades of fatty liver was found to be positively correlated with the changes in serum levels of periostin (rs=0.306, P=0.041 and adiponectin (rs=0.314, P=0.036, whereas the associations were insignificant with the change in serum levels of TNF-α (rs=0.053, P=0.729. Mild gastrointestinal side effects (20% were reported in the orlistat group. In conclusion, orlistat is

    lnfratentorial low grade astrocytoma (ILGA) occurs rarely in adult patients and accounts for about 3% of all intracranial tumors.The basic method of treatment for ILGA is surgery. Complete resection results in high local control rate and the role of postoperative irradiation in management of partially resected tumors is not clearly determined. The aim of this study was to evaluate the efficacy of postoperative irradiation in adult patients with incompletely excised ILGA. Between 1975 and 1995, thirty one adult patients with incompletely excised ILGA received postoperative irradiation with curative intent. All patients were treated with megavoltage gamma rays ( 60C o). The total dose ranged from 50 to 60 Gy (mean; 54 Gy) and was delivered with daily fraction of 1.8-2 Gy. The treatment volume covered the tumor being area with a margin of 1-2 cm. Tolerance to treatment has been found to be good in 30 patients (97%). The overall 15-year actuarial survival rate was 62% in the entire group. Young patients, up to twenty years of age achieved a 15-year overall actuarial survival rate of 85%, older patients - 46%. This difference was statistically significant (p =0. 0205). Conventionally fractionated postoperative radiotherapy with doses of 50 to 60 Gy may improve long term results of adult patients with ILGA after uncomplete resection. Age is a significant prognostic factor - young patients, up to twenty years of age, show best survival. (author)

    Patients with nonspecific mechanical low back pain (n = 103), examined by an orthopaedic surgeon and a social worker, were randomized to an activity group (n = 51) and a control group (n = 52). Patients with defined orthopaedic, medical, or psychiatric diagnoses were excluded before randomization. No patients were excluded due to place of birth or difficulties in speaking or understanding the Swedish language. The purpose of the study was to compare mobility, strength and fitness after traditional care and after traditional care plus a graded activity program with a behavioral therapy approach. A graded activity program, with a behavioral therapy approach was given under the guidance of a physical therapist. The endpoint of the graded activity program was return to work. This program significantly increased mobility, strength, and fitness more than could be explained by only a time recovery effect, especially in males. The patients in the activity group returned to work earlier than did the patients in the control group. Spinal rotation, abdominal muscle endurance time and lifting capacity were significantly correlated to rate of return to work. Traditional care plus a graded activity program were superior to only traditional care, evaluated in terms of mobility, strength and fitness. The graded activity program proved to be a successful method of restoring occupational function and facilitating return to work in subacute low back pain patients. The patients in the graded activity program learned that it is safe to move, while regaining function.

    Full Text Available CONTEXT AND OBJECTIVE: Cervical cancer is a serious public health problem in Brazil. For patients with unsatisfactory colposcopic examinations without visible lesions, but with cervical cytological tests suggesting high-grade squamous intraepithelial lesion (HSIL, the national recommendation is to repeat cervical cytological tests after three months. Our aim was to assess the prevalence of HSIL and cancer among patients with initial cervical cytological tests suggestive of HSIL but with unsatisfactory colposcopic examinations without visible lesions, in order to contribute towards the discussion regarding a more effective clinical approach that might diminish the likelihood of patient abandonment of follow-up before appropriate diagnosis and treatment. DESIGN AND SETTING: Cross-sectional study in Colposcopy Clinic of IFF/Fiocruz. METHOD: Patients admitted between December 1989 and April 2007 with cytological diagnoses of HSIL but with unsatisfactory colposcopic examinations without visible lesions underwent cervical cone biopsy. RESULTS: Sixty-five such patients were included, comprising 33.8% with HSIL and 4.6% with cancer, confirmed histologically. The other patients presented low-grade squamous intraepithelial lesion (26.1%, glandular dysplasia (1.5% and absence of disease (33.8%. CONCLUSION: The observed prevalence of cancer and HSIL does not seem to be enough to justify immediate referral for cone biopsies to investigate the cervical canal in these cases. The findings suggest that the recommendation of repeated cytological tests following an initial one with HSIL, among patients with unsatisfactory colposcopic examinations without visible lesions, is appropriate in our setting. Efforts are needed to ensure adherence to follow-up protocols in order to reduce the chances of losses.

    Purpose: To present the effect of radiotherapy doses to different volumes of normal structures on neurocognitive outcomes in young patients with benign and low-grade brain tumors treated prospectively with stereotactic conformal radiotherapy (SCRT). Methods and Materials: Twenty-eight patients (median age, 13 years) with residual/progressive brain tumors (10 craniopharyngioma, 8 cerebellar astrocytoma, 6 optic pathway glioma and 4 cerebral low-grade glioma) were treated with SCRT to a dose of 54 Gy in 30 fractions over 6 weeks. Prospective neuropsychological assessments were done at baseline before RT and at subsequent follow-up examinations. The change in intelligence quotient (IQ) scores was correlated with various factors, including dose-volume to normal structures. Results: Although the overall mean full-scale IQ (FSIQ) at baseline before RT remained unchanged at 2-year follow-up after SCRT, one third of patients did show a >10% decline in FSIQ as compared with baseline. Logistic regression analysis demonstrated that patients aged 10% drop in FSIQ than older patients (53% vs. 10%, p = 0.03). Dosimetric comparison in patients showing a >10% decline vs. patients showing a 43.2 Gy to >13% of volume of the left temporal lobe were the ones to show a significant drop in FSIQ (p = 0.048). Radiotherapy doses to other normal structures, including supratentorial brain, right temporal lobe, and frontal lobes, did not reveal any significant correlation. Conclusion: Our prospectively collected dosimetric data show younger age and radiotherapy doses to left temporal lobe to be predictors of neurocognitive decline, and may well be used as possible dose constraints for high-precision radiotherapy planning.

    Purpose: To study the relationship of tumor grade to the distribution of pathologic features and to the risk of local and distant recurrence following breast-conserving therapy in patients with pure infiltrating ductal carcinoma, and to explore the differences between this type and tubular carcinoma. Materials and Methods: Between 1968 and 1986, 1624 patients were treated for clinical Stage I or II invasive breast cancer with a complete gross excision and {>=}60 Gy to the tumor bed. The original slides were reviewed in 1337 cases (82%). Of these, 1081 were pure infiltrating ductal carcinoma and 28 were tubular carcinoma and these constitute the study population. Fifty-five patients (5%) have been lost to followup after 7-181 months. Median followup for 742 survivors is 134 months (7-278 mos.). We evaluated the following features: histologic grade (modified Bloom-Richardson system), the presence of nodal metastases (in 891 pts. (80%) undergoing axillary dissection [pLN+]), an extensive intraductal component (EIC), lymphatic vessel invasion (LVI), mononuclear cellular response (MCR), and necrosis. We analyzed the incidence of clinical and pathologic characteristics as a function of histology and histologic grade (Table 1). We also examined the 10-year crude rates of first failure for evaluable patients (Table 2) and calculated actuarial curves for regional nodal failure or distant metastasis (RNF/DM) at any time during followup (Figure 1). Results: Conclusions: 1) The proportion of tumors with LVI, EIC, or lymph node involvement did not vary significantly by histologic grade. Low grade tumors tended to be smaller and exhibit less MCR and necrosis; 2) Grade did not predict for local recurrence. Distant recurrence rates were significantly higher in patients with grade II or III as compared with grade I tumors, although recurrence rates continued to rise for grade I tumors through 10 years of followup; 3) Although patient numbers are small, tubular breast carcinomas

    Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.

    Mac-2 Binding Protein Glycosylation Isomer (M2BPGi) is a novel fibrosis marker. We examined the ability of M2BPGi to predict liver fibrosis in patients with biliary atresia. Sixty-four patients who underwent living donor liver transplantation (LDLT) were included [median age, 1.1 years (range 0.4-16.0), male 16 patients (25.0 %)]. We examined M2BPGi levels in serum obtained the day before LDLT, and we compared the value of the preoperative M2BPGi levels with the histological evaluation of fibrosis using the METAVIR fibrosis score. Subsequently, we assessed the ability of M2BPGi levels to predict fibrosis. The median M2BPGi level in patients with BA was 6.02 (range, 0.36-20.0), and 0, 1, 1, 11, and 51 patients had METAVIR fibrosis scores of F0, F1, F2, F3, and F4, respectively. In patients with F4 fibrosis, the median M2BPGi level was 6.88 (quartile; 5.235, 12.10), significantly higher than that in patients with F3 fibrosis who had a median level of 2.42 (quartile; 1.93, 2.895, p F4 fibrosis. M2BPGi is a novel fibrosis marker for evaluating the status of the liver in patients with BA, especially when predicting grade F4 fibrosis.

    The purpose of this study was to evaluate the clinical utility of laser-induced thermotherapy (LITT) as a palliative treatment for patients with high-grade gliomas. Four consenting patients with recurrent high grade III/IV gliomas near the primary language or motor areas were palliatively treated with LITT (2-5 W, 3-13 minutes; Neodym YAG Laser, Dornier, Friedrichshafen, Germany). Temperature monitoring was performed by T1-weighted turbo-fast low-angle shot (FLASH) imaging at 1.5 T (Siemens Magnetom SP 4000, Siemens, Erlangen, Germany). MRI studies before LITT included contrast-enhanced conventional scans and functional activation studies to localize the primary motor cortex or language areas using an echo-planar imaging (EPI) spin-echo (SE) sequence. Follow-up studies consisted of contrast-enhanced conventional scans as well as diffusion studies (contrast-enhanced Fourier-acquired steady-state technique and EPI-SE) and perfusion studies (EPI-SE with .2 mmol of gadolinium (Gd)/kg body weight) to differentiate post-therapeutic effects from residual or recurrent tumor growth. Local tumor control was achieved in areas with laser energy deposition with clinically stable conditions > or = 6 months. Conventional contrast-enhanced scans demonstrated strong enhancement surrounding ablated tumor components, which showed a reduction in CBV/CBF. Perfusion studies were useful to discriminate granulomatous tissue enhancement from residual or recurrent tumor growth. Careful application of LITT may evolve as an alternative palliative concept for patients with end-stage high-grade cerebral gliomas reducing clinical symptoms from circumscribed areas of pathology.

    Health and social care provision for an ageing population is a global priority. Provision for those with dementia and hip fracture has specific and growing importance. Older people who break their hip are recognised as exceptionally vulnerable to experiencing confusion (including but not exclusively, dementia and/or delirium and/or cognitive impairment(s)) before, during or after acute admissions. Older people experiencing hip fracture and confusion risk serious complications, linked to delayed recovery and higher mortality post-operatively. Specific care pathways acknowledging the differences in patient presentation and care needs are proposed to improve clinical and process outcomes. This protocol describes a multi-centre, feasibility, cluster-randomised, controlled trial (CRCT) to be undertaken across ten National Health Service hospital trusts in the UK. The trial will explore the feasibility of undertaking a CRCT comparing the multicomponent PERFECTED enhanced recovery intervention (PERFECT-ER), which acknowledges the differences in care needs of confused older patients experiencing hip fracture, with standard care. The trial will also have an integrated process evaluation to explore how PERFECT-ER is implemented and interacts with the local context. The study will recruit 400 hip fracture patients identified as experiencing confusion and will also recruit "suitable informants" (individuals in regular contact with participants who will complete proxy measures). We will also recruit NHS professionals for the process evaluation. This mixed methods design will produce data to inform a definitive evaluation of the intervention via a large-scale pragmatic randomised controlled trial (RCT). The trial will provide a preliminary estimate of potential efficacy of PERFECT-ER versus standard care; assess service delivery variation, inform primary and secondary outcome selection, generate estimates of recruitment and retention rates, data collection difficulties, and

    BACKGROUND: The protease inhibitor darunavir has been shown to be efficacious in highly treatment-experienced patients with HIV infection, but needs to be assessed in patients with a broader range of treatment experience. We did a randomised, controlled, phase III trial (TITAN) to compare 48-week....... The primary endpoint was non-inferiority (95% CI lower limit for the difference in treatment response -12% or greater) for HIV RNA of less than 400 copies per mL in plasma at week 48 (per-protocol analysis). TITAN (TMC114-C214) is registered with ClinicalTrials.gov, number NCT00110877. FINDINGS: Of 595...

    Purpose: The pattern of failure of low grade gliomas following radiotherapy is less well known than that of the high grade gliomas. Stereotactic histologic studies have suggested that tumor cells extend beyond imaging abnormalities, and that large margins would be required for radiotherapy target volumes to encompass all of the neoplasm. Our experience using computerized tomography (CT)- and magnetic resonance (MR)-planned irradiation of low grade gliomas was reviewed to determine the pattern of tumor recurrence, in an effort to clinically define the minimum margin required. Methods and Materials: Forty-six patients with low grade supratentorial gliomas were treated between April 1985 and November 1992 using three-dimensional (3D) conformal CT- or MR-planned external beam radiotherapy. Fields were designed to encompass a target volume created by adding a margin to the tumor in three dimensions. Generally, patients were treated using shrinking fields with an initial target (tumor plus a 1 to 3 cm margin) treated to a dose of 45 to 50.4 (median 50.4) Gy, and a boost (tumor plus a 0 to 2 cm margin) treated to a total of 54 to 59.4 (median 59.4) Gy. Median follow-up was 32.9 months. Results: There have been 11 failures; all of these occurred within the radiographic abnormality (either T2 prolongation or CT hypodensity) visualized at the time of treatment planning (i.e., all failures were within the boost volume). Median time to failure was 53 months. Because all failures were local, there was no relationship between the amount by which the tumor volumes were expanded to create target volumes and the eventual outcome. Conclusion: Despite pathologic data suggesting that low grade glioma cells can be found outside the MR T2-signal abnormality in many cases, our results demonstrate that conformal external beam radiotherapy, in which the high dose volume is limited, does not result in increased marginal or out-of-field failures. Until control of tumor within the

    To evaluate albumin-bilirubin (ALBI) and platelet-albumin-bilirubin (PALBI) grades in predicting overall survival in high-risk patients undergoing conventional transarterial chemoembolization for hepatocellular carcinoma (HCC). This single-center retrospective study included 180 high-risk patients (142 men, 59 y ± 9) between April 2007 and January 2015. Patients were considered high-risk based on laboratory abnormalities before the procedure (bilirubin > 2.0 mg/dL, albumin 1.2 mg/dL); presence of ascites, encephalopathy, portal vein thrombus, or transjugular intrahepatic portosystemic shunt; or Model for End-Stage Liver Disease score > 15. Serum albumin, bilirubin, and platelet values were used to determine ALBI and PALBI grades. Overall survival was stratified by ALBI and PALBI grades with substratification by Child-Pugh class (CPC) and Barcelona Liver Clinic Cancer (BCLC) stage using Kaplan-Meier analysis. C-index was used to determine discriminatory ability and survival prediction accuracy. Median survival for 79 ALBI grade 2 patients and 101 ALBI grade 3 patients was 20.3 and 10.7 months, respectively (P  .05). ALBI and PALBI grades are accurate survival metrics in high-risk patients undergoing conventional transarterial chemoembolization for HCC. Use of these scores allows for more refined survival stratification within CPC and BCLC stage. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

    We report data from two similarly designed studies that evaluated the efficacy, safety, and optimal duration of ledipasvir/sofosbuvir (LDV/SOF) ± ribavirin (RBV) for retreatment of chronic hepatitis C virus (HCV) in individuals who failed to achieve sustained virological response (SVR) with prior SOF-based, non-NS5A inhibitor-containing regimens. The RESCUE study enrolled HCV mono-infected adults with genotype (GT) 1 or 4. Non-cirrhotic participants were randomized to 12 weeks of LDV/SOF or LDV/SOF + RBV. Compensated cirrhotic participants were randomized to LDV/SOF + RBV (12 weeks) or LDV/SOF (24 weeks). The AIDS Clinical Trials Group A5348 study randomized genotype 1 adults with HCV/HIV co-infection to LDV/SOF + RBV (12 weeks) or LDV/SOF (24 weeks). Both studies used SVR at 12 weeks post-treatment (SVR12) as the primary endpoint. In the RESCUE study, 82 participants were randomized and treated, and all completed treatment. Overall, SVR12 was 88% (72/82); 81-100% in non-cirrhotic participants treated with LDV/SOF or LDV/SOF + RBV for 12 weeks and 80-92% in cirrhotic participants treated with LDV/SOF + RBV for 12 weeks or LDV/SOF for 24 weeks. Adverse events (AEs), mostly mild-to-moderate in severity, were experienced by 78% of participants, with headache and fatigue most frequently reported. One serious AE, not related to treatment, was observed. No premature discontinuations of study drug, or deaths occurred. In the A5348 study, seven participants were randomized (cirrhotic n = 1; GT1a n = 5) and all attained SVR12, with no serious AEs or premature discontinuations. In this SOF-experienced, NS5A inhibitor-naïve population, which included participants with cirrhosis or HCV/HIV co-infection, high SVR12 rates were achieved. © 2017 John Wiley & Sons A/S.

    Purpose: Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) selectively induces apoptosis in cancer cells but not in normal cells, and a number of clinical trials have recently been initiated to test the safety and antitumoral potential of TRAIL in cancer patients. Four different receptors have been identified to interact with TRAIL: two are death-inducing receptors (TRAIL-R1 [DR4] and TRAIL-R2 [DR5]), whereas the other two (TRAIL-R3 [DcR1] and TRAIL-R4 [DcR2]) do not induce death upon ligation and are believed to counteract TRAIL-induced cytotoxicity. Because high levels of DcR2 expression have recently been correlated with carcinogenesis in the prostate and lung, this study investigated the importance of TRAIL and TRAIL receptor expression in breast cancer patients with invasive ductal carcinoma, taking various prognostic markers into consideration. Methods and Materials: Immunohistochemical analyses were performed on 90 breast cancer patients with invasive ductal carcinoma using TRAIL and TRAIL receptor-specific antibodies. Age, menopausal status, tumor size, lymph node status, tumor grade, lymphovascular invasion, perineural invasion, extracapsular tumor extension, presence of an extensive intraductal component, multicentricity, estrogen and progesterone receptor status, and CerbB2 expression levels were analyzed with respect to TRAIL/TRAIL receptor expression patterns. Results: The highest TRAIL receptor expressed in patients with invasive ductal carcinoma was DR4. Although progesterone receptor-positive patients exhibited lower DR5 expression, CerbB2-positive tissues displayed higher levels of both DR5 and TRAIL expressions. Conclusions: DR4 expression positively correlates with the tumor grade in breast cancer patients with invasive ductal carcinoma

    The aim of this study is to clarify the association between subventricular zone (SVZ) involvement and velocity of diametric expansion(VDE) in patients with low-grade astrocytoma and also assessed the clinical outcome of those patients. A total of 168 adult patients with newly diagnosed supratentorial low-grade astrocytoma were studied retrospectively. There were 73 patients had SVZ involvement. Patients with SVZ involvement(7.16 ± 6.53 mm/y) had a higher VDE than patients without SVZ involvement(4.38 ± 5.35 mm/y). VDE was modeled as a categorical variable(<4, ≥4 and, <8, ≥8 and, <12, ≥12 mm/y). Logistic regression showed that SVZ involvement was associated with high VDE after adjusting by confounding variables. On the univariate analysis, the results showed that tumor involved with SVZ, VDE ≥ 4 mm/y, VDE ≥ 8 mm/y, and VDE ≥ 8 mm/y were significant predictors of a shorter OS, progression-free survival (PFS) and malignant progression-free survival (MFS)(all p <0.05). The categorical variables of VDE (<4 mm/y, ≥4 mm/y and, <8 mm/y, ≥8 mm/y and, <12 mm/y, ≥12 mm/y) were adjusted by confounding variables in multivariate analysis, respectively. The results indicated that VDE ≥ 8 mm/y, VDE ≥ 12 mm/y were worse prognostic factors for OS, while VDE ≥ 4 mm/y, VDE ≥ 8 mm/y and VDE ≥ 12 mm/y were related to shorter PFS and MFS. In addition, SVZ involvement was prognostic factors in predicting OS and PFS except MFS. Our results demonstrated that SVZ involvement predicted high VDE and worse clinical outcome, and high VDE was associated with poor prognosis in patients with low-grade astrocytoma.

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

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

    Full Text Available In patients with genotype 1 chronic hepatitis C infection, telaprevir (TVR in combination with peginterferon and ribavirin (PR significantly increased sustained virologic response (SVR rates compared with PR alone. However, genotypic changes could be observed in TVR-treated patients who did not achieve an SVR.Population sequence analysis of the NS3•4A region was performed in patients who did not achieve SVR with TVR-based treatment.Resistant variants were observed after treatment with a telaprevir-based regimen in 12% of treatment-naïve patients (ADVANCE; T12PR arm, 6% of prior relapsers, 24% of prior partial responders, and 51% of prior null responder patients (REALIZE, T12PR48 arms. NS3 protease variants V36M, R155K, and V36M+R155K emerged frequently in patients with genotype 1a and V36A, T54A, and A156S/T in patients with genotype 1b. Lower-level resistance to telaprevir was conferred by V36A/M, T54A/S, R155K/T, and A156S variants; and higher-level resistance to telaprevir was conferred by A156T and V36M+R155K variants. Virologic failure during telaprevir treatment was more common in patients with genotype 1a and in prior PR nonresponder patients and was associated with higher-level telaprevir-resistant variants. Relapse was usually associated with wild-type or lower-level resistant variants. After treatment, viral populations were wild-type with a median time of 10 months for genotype 1a and 3 weeks for genotype 1b patients.A consistent, subtype-dependent resistance profile was observed in patients who did not achieve an SVR with telaprevir-based treatment. The primary role of TVR is to inhibit wild-type virus and variants with lower-levels of resistance to telaprevir. The complementary role of PR is to clear any remaining telaprevir-resistant variants, especially higher-level telaprevir-resistant variants. Resistant variants are detectable in most patients who fail to achieve SVR, but their levels decline over time after treatment.

Physicians and patients have the choice between various methods of administration. For subcutaneous immunoglobulin infusions, patients may use an automated pump (P or push the plunger of a syringe (rapid push [RP]. P infusions are performed once a week and last around 1 hour. RP decreases the duration of administration, but requires more frequent infusions.Patients and methods: Eight out of 30 patients (coming from a single center who had participated in the cross-over, randomized, open-label trial comparing P and RP participated in a focus group or underwent in-depth interviews. Patients had a long history of home-based subcutaneous immunoglobulin using P. The trial suggested that RP had slightly greater interference on daily life than P, but similar efficacy and better cost-effectiveness. When asked about the delivery method they had preferred, around one-third of patients pointed out RP rather than P. In-depth interviews may reveal unforeseen reasons for patients’ preferences. Results: Interviews underlined the complexity of the relationship that the patients maintain with their disease and IgRT. Even if they recognized the genetic nature of the disease and claimed PID was a part of them, patients tried not to be overwhelmed by the disease. IgRT by P was well integrated in patients’ routine. By contrast, RP too frequently reminded the patients of their disease. In addition, some patients pointed out the difficulty of pushing the plunger due to the viscosity of the product. Coming back too frequently, RP was not perceived

    Positron emission tomography (PET) was evaluated in low-grade non-Hodgkin lymphoma (NHL) to determine its impact on staging and management and to compare PET and gallium scans. PET resulted in management plan changes in 74 patients with untreated low-grade NHL stages I to III. Patient outcomes to 12 months were documented. PET identified additional lesions in 50% of patients, led to a change in stage in 32%, and had a significant impact on management in 34%. Inferior progression-free survival was noted in patients with additional lesions detected by PET (p=0.001) and in the 28% of patients upstaged by PET to stage III or IV (p=0.024). In a subset of 16 patients undergoing both PET and gallium scans, PET was found to be superior. PET has a major role in the management of low-grade NHL in addition to its proven role in aggressive lymphoma. (orig.)

    To determine interrelationship between lower limb varicosity, the clinical grade of non-differentiated dysplasia of the connective tissue and atrial fibrillation in patients with coronary artery disease (CAD). Altogether 156 coronary patients were examined. Persistent atrial fibrillation was present in 58 and chronic in 38 patients. The reference group comprised 60 patients without evident rhythm disorders in persons suffering from CAD. Markers of connective tissue dysplasia () were revealed on the part of the skeleton, joints skin and visceral organs. Lower limb varicosity was recorded as well. The number of the stigmas in the study groups was different. So, in the patient group without rhythm disorders, the mean number of the stigmas was equal to 3, which is a variant of normal. In the groups with persistent and constant AF, this indicator was equal to 4.7 and 5.2 respectively (patrial fibrilation there is a direct close correlation between the signs of connective tissue dysplasia and lower limb varicosity. In patients with persistent AF lower limb varicosity occurs more frequently than in CAD patients with normal rhythm.

    Full Text Available The development of tipranavir and darunavir, second generation non-peptidic HIV protease inhibitors, with marked improved resistance profiles, has opened a new perspective on the treatment of antiretroviral therapy (ART experienced HIV patients with poor viral load control. The aim of this study was to determine the virologic response in ART experienced patients to tipranavir-ritonavir and darunavir-ritonavir based regimens.A computer based literature search was conducted in the databases of HINARI (Health InterNetwork Access to Research Initiative, Medline and Cochrane library. Meta-analysis was performed by including randomized controlled studies that were conducted in ART experienced patients with plasma viral load above 1,000 copies HIV RNA/ml. The odds ratios and 95% confidence intervals (CI for viral loads of <50 copies and <400 copies HIV RNA/ml at the end of the intervention were determined by the random effects model. Meta-regression, sensitivity analysis and funnel plots were done. The number of HIV-1 patients who were on either a tipranavir-ritonavir or darunavir-ritonavir based regimen and achieved viral load less than 50 copies HIV RNA/ml was significantly higher (overall OR = 3.4; 95% CI, 2.61-4.52 than the number of HIV-1 patients who were on investigator selected boosted comparator HIV-1 protease inhibitors (CPIs-ritonavir. Similarly, the number of patients with viral load less than 400 copies HIV RNA/ml was significantly higher in either the tipranavir-ritonavir or darunavir-ritonavir based regimen treated group (overall OR = 3.0; 95% CI, 2.15-4.11. Meta-regression showed that the viral load reduction was independent of baseline viral load, baseline CD4 count and duration of tipranavir-ritonavir or darunavir-ritonavir based regimen.Tipranavir and darunavir based regimens were more effective in patients who were ART experienced and had poor viral load control. Further studies are required to determine their consistent

    In the assessment of patients with chest pain, there is support for the use of pre-hospital ECG in the literature and in the care guidelines. Using propensity score methods, we aim to examine whether the mere acquisition of a pre-hospital ECG among patients with chest pain affects the outcome (30-day mortality). The association between pre-hospital ECG and 30-day mortality was studied in the overall cohort (n=13151), as well as in the one-to-one matched cohort with 2524 patients not examined with pre-hospital ECG and 2524 patients examined with pre-hospital ECG. In the overall cohort, 21% (n=2809) did not undergo an ECG tracing in the pre-hospital setting. Among those who had pain during transport, 14% (n=1159) did not undergo a pre-hospital ECG while 32% (n=1135) of those who did not have pain underwent an ECG tracing. In the overall cohort, the OR for 30-day mortality in patients who had a pre-hospital ECG, as compared with those who did not, was 0.63 (95% CI 0.05-0.79; pECG was used. The PH-ECG is underused among patients with chest discomfort and the mere acquisition of a pre-hospital ECG may reduce mortality. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objectives: Deficient microvascular blood flow control is thought to cause tumor hypoxia and increase resistance to therapy. In glioma patients, we tested whether perfusion-weighted MRI (PWI) based indices of microvascular flow control provide more information on tumor grade and patient outcome...... than does the established PWI angiogenesis marker, cerebral blood volume (CBV). Material and Methods: Seventy-two glioma patients (sixty high-grade, twelve low-grade gliomas) were included. Capillary transit time heterogeneity (CTH) and COV, its ratio to blood mean transit time, provide indices...... of microvascular flow control and the extent to which oxygen can be extracted by tumor tissue. The ability of these parameters and CBV to differentiate tumor grade were assessed by receiver operating characteristic curves and logistic regression. Their ability to predict time to progression and overall survival...

  10. The impact of pre-injury anticoagulation therapy in the older adult patient experiencing a traumatic brain injury: A systematic review.

    The objective of this systematic review is to synthesize the best available evidence on the impact of pre-injury anticoagulation therapy in the older adult patient who experiences a traumatic brain injury. Trauma in the elderly remains one of the most challenging problems for healthcare providers in the 21 century. The most recent United States (U.S.) census estimates that by the year 2020 more than 52 million Americans will be age 65 years or older, and one million of those will live to be over 100 years of age. In the older adult population, classified as age 65 years or greater, the two leading causes of injury were reported as motor vehicle crashes (MVC) and falls. We have become increasingly aware of the unique physiologic changes in this population that make them more susceptible to succumb to traumatic injuries than their younger counterparts. This is especially true in the anticoagulated patient with a traumatic brain injury.Traumatic brain injury (TBI) is defined as an injury occurring when an external force traumatizes the brain. It may also be known as an intracranial or head injury. TBI is classified depending on the mechanism of injury (blunt or penetrating), severity, and location of the assault. Damage to the brain, skull, and/or scalp transpires. TBI is the leading cause of death and disability in the U.S, and persons of all ages, races, ethnicities, and incomes are affected. In the past five to ten years, trauma services have recorded an increase in major trauma admissions of patients age 65 years and older. In review of the literature to date, it is recognized that outcomes following moderate to severe TBI in older adults are poor, with high rates of significant disability and mortality reported. A recent Australian study reported that 28% of older adults died in the hospital following a TBI and in Finland adults aged 75 years and older had the highest rates of TBI related hospitalizations and death. According to a systematic review of European

    The impact on mortality due to prompt recognition of ST-segment Elevation Myocardial Infarction (STEMI) patients by EMS has not been well described. The objective of this study was to describe the association between the time interval, 9-1-1 call to percutaneous intervention (PCI), and mortality at one year. This retrospective analysis included patients that were transported by EMS as a "code STEMI" and underwent PCI.  Total time from 9-1-1 call to PCI was calculated for each patient and was the independent variable of interest. Each patient's mortality status at one year was the outcome variable, collected by querying medical records and the national death index. Confounding variables were abstracted from hospital records. Logistic regression was conducted to determine the likelihood of survival given differences in time to PCI. A total of 550 patients were included in the analyses of which 68% were male with an average age 59.8 (SD 12.8). Mean reperfusion time was 81.8 min (SD 20.0) and was significantly lower in patients alive at one year (80.8 min, SD 19.7) vs. deceased at one year (93.9 min, SD 19.6), respectively. Odds of survival at one year decreased by 3% (OR 0.97; 95% CI 0.96-0.99) for every one minute increase in time to PCI. This relationship practically represents a 30% increase in mortality for every 10 minute delay from 9-1-1 call to PCI. The model produced suggests that a linear relationship exists between time to PCI and mortality in the prehospital environment with the probability of survival decreasing significantly as time to PCI increases.

    A buccal film of buprenorphine (BBUP) was evaluated for safety and efficacy in a multicenter, double-blind, placebo-controlled, enriched-enrollment, randomized-withdrawal study in opioid-experienced patients (30 to ≤160 mg/d morphine sulfate equivalent) with moderate to severe chronic low back pain taking around-the-clock opioid analgesics. Patients' opioid doses were tapered to ≤30 mg morphine sulfate equivalent before open-label titration with BBUP (range, 150-900 μg every 12 hours). Patients who responded (received adequate analgesia that was generally well tolerated for 14 days) were randomized to receive buprenorphine (n = 254) or placebo (n = 257) buccal film. The primary efficacy variable was the change from baseline to week 12 of double-blind treatment in mean average daily pain-intensity scores using a rating scale of 0 (no pain) to 10 (worst pain imaginable). In the intent-to-treat population, mean pain scores were 6.7 after opioid taper and declined to 2.8 after the BBUP titration period. After randomization, mean pain scores were lower in the BBUP group than in the placebo group; the difference between groups in the mean change from baseline to week 12 was -0.98 (95% CI, -1.32 to -0.64; P opioid-experienced patients taking around-the-clock opioid treatment for chronic low back pain.

    To evaluate efficacy and safety of 60mg and 120mg Fimasartan (FMS) alone or combined with 12.5mg hydrochlorothiazide (HCTZ) in a Mexican population. A six month, treat-to-target, open study was conducted on subjects with grade 1-2 hypertension. The subjects were initially treated with 60mg FMS once daily. In week 8, those with Diastolic Blood Pressure (DBP) <90mmHg continued on the same FMS dose during the rest of the study, while those with DBP ≥90mmHg were randomised to either 120mg FMS or 60mg FMS + 12.5mg HCTZ once daily. In week 12, randomised subjects with DBP ≥90mmHg received 120mg FMS+12.5mg HCTZ, while those achieving target continued with their assigned treatment until the end of the study. FMS 60mg (n=272) decreased both DBP and Systolic Blood Pressure (SBP) by 11.3±8.9 (p<.0001) and 16.0±14.1 (p<.0001)mmHg, respectively, with 75.4% of subjects reaching the treatment target. Subjects assigned to FMS 120mg, FMS 60mg+HCTZ 12.5mg, or FMS 120mg+HCTZ 12.5mg once daily, showed significant reductions in DBP and SBP with their assigned treatment. At the end of the study, 237/272 subjects (87.1%) achieved a DBP<90mmHg and an SBP<140mmHg. The most frequently reported adverse reactions included headache (3.7%), dry mouth (1.1%), transient liver enzyme increase (1.1%), and dizziness (0.7%). Fimasartan is safe and effective in Mexican subjects with grade 1-2 essential hypertension. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A.

    An important aspect in functional imaging research employing magnetic resonance imaging (MRI) is how participants perceive the MRI scanning itself. For instance, the knowledge of how (un)comfortable MRI scanning is perceived may help institutional review boards (IRBs) or ethics committees to decide on the approval of a study, or researchers to design their experiments. We provide empirical data from our lab gained from 70 neurologically healthy mainly student subjects and from 22 mainly elderly patients suffering from motor deficits after brain damage. All participants took part in various basic research fMRI studies using a 3T MRI scanner. Directly after the scanning, all participants completed a questionnaire assessing their experience with the fMRI procedure. 87.2% of the healthy subjects and 77.3% of the patients rated the MRI procedure as acceptable to comfortable. In healthy subjects, males found the procedure more comfortable, while the opposite was true for patients. 12.1% of healthy subjects considered scanning durations between 30 and 60 min as too long, while no patient considered their 30 min scanning interval as too long. 93.4% of the healthy subjects would like to participate in an fMRI study again, with a significantly lower rate for the subjects who considered the scanning as too long. Further factors, such as inclusion of a diffusion tensor imaging (DTI) scan, age, and study duration had no effect on the questionnaire responses. Of the few negative comments, the main issues were noise, the restriction to keep still for the whole time, and occasional feelings of dizziness. MRI scanning in the basic research setting is an acceptable procedure for elderly and patient participants as well as young healthy subjects

    Patients with fibromyalgia frequently present with symptoms similar to those experienced by patients with gluten-related disorders, raising the possibility that a subgroup of these patients could be experiencing underlying gluten sensitivity. This study aimed to evaluate the effects of a gluten-free diet (GFD) compared with a hypocaloric diet (HCD) among patients with fibromyalgia. Adult patients diagnosed with fibromyalgia were randomly allocated to receive a GFD or a HCD over a 24-week period. The primary outcome measure was the change in the number of gluten sensitivity symptoms. The following secondary outcomes were evaluated: body mass index, Revised Fibromyalgia Impact Questionnaire, Pittsburgh Sleep Quality Index, Brief Pain Inventory, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Short-Form Health Survey, Patient Global Impression Scale of Severity, Patient Global Impression Scale of Improvement, and adverse events. Seventy-five subjects were randomly allocated to receive either a GFD (n=35) or an HCD (n=40). The least squares mean change in the total number of gluten sensitivity symptoms from baseline did not differ significantly between the GFD and HCD groups (-2.44±0.40 for the GFD; -2.10±0.37 for the HCD; P=0.343). Similarly, the 2 dietary interventions did not differ in any of the remaining measured secondary outcomes. Both dietary interventions were well tolerated. Both dietary interventions were associated with similar beneficial outcomes in reducing gluten sensitivity symptoms and other secondary outcomes. However, despite its specificity, GFD was not superior to HCD in reducing the number of gluten sensitivity symptoms or secondary outcomes.

    Purpose: We tested the validity of 3 recently proposed prognostic indexes for breast cancer patients with brain metastases (METs) treated radiosurgically. The 3 indexes are Diagnosis-Specific Graded Prognostic Assessment (DS-GPA), New Breast Cancer (NBC)-Recursive Partitioning Analysis (RPA), and our index, sub-classification of RPA class II patients into 3 sub-classes (RPA class II-a, II-b and II-c) based on Karnofsky performance status, tumor number, original tumor status, and non-brain METs. Methods and Materials: This was an institutional review board-approved, retrospective cohort study using our database of 269 consecutive female breast cancer patients (mean age, 55 years; range, 26-86 years) who underwent Gamma Knife radiosurgery (GKRS) alone, without whole-brain radiation therapy, for brain METs during the 15-year period between 1996 and 2011. The Kaplan-Meier method was used to estimate the absolute risk of each event. Results: Kaplan-Meier plots of our patient series showed statistically significant survival differences among patients stratified into 3, 4, or 5 groups based on the 3 systems (P<.001). However, the mean survival time (MST) differences between some pairs of groups failed to reach statistical significance with all 3 systems. Thus, we attempted to regrade our 269 breast cancer patients into 3 groups by modifying our aforementioned index along with the original RPA class I and III, (ie, RPA I+II-a, II-b, and II-c+III). There were statistically significant MST differences among these 3 groups without overlap of 95% confidence intervals (CIs) between any 2 pairs of groups: 18.4 (95% CI = 14.0-29.5) months in I+II-a, 9.2 in II-b (95% CI = 6.8-12.9, P<.001 vs I+II-a) and 5.0 in II-c+III (95% CI = 4.2-6.8, P<.001 vs II-b). Conclusions: As none of the new grading systems, DS-GPS, BC-RPA and our system, was applicable to our set of radiosurgically treated patients for comparing survivals after GKRS, we slightly modified our system for breast cancer

  19. Prevalence and factors associated with darunavir resistance mutations in multi-experienced HIV-1-infected patients failing other protease inhibitors in a referral teaching center in Brazil

    Jose E Vidal

    Full Text Available Information about resistance profile of darunavir (DRV is scarce in Brazil. Our objectives were to estimate the prevalence of DRV resistance mutations in patients failing protease inhibitors (PI and to identify factors associated with having more DRV resistance mutations. All HIV-infected patients failing PI-based regimens with genotyping performed between 2007 and 2008 in a referral teaching center in São Paulo, Brazil, were included. DRV-specific resistance mutations listed by December 2008 IAS-USA panel update were considered. Two Poisson regression models were constructed to assess factors related to the presence of more DRV resistance mutations. A total of 171 HIV-infected patients with available genotyping were included. The number of patients with lopinavir, saquinavir, and amprenavir used in previous regimen were 130 (76%, 83 (49%, and 35 (20%, respectively. The prevalence of major DRV resistance mutations was 50V: 5%; 54M: 1%; 76V: 4%; 84V: 15%. For minor mutations, the rates were 11I: 3%; 32I: 7%; 33F: 23%; 47V: 6%; 54L: 6%; 74P: 3%; 89V: 6%. Only 11 (6% of the genotypes had > 3 DRV resistance mutations. In the clinical model, time of HIV infection of > 10 years and use of amprenavir were independently associated with having more DRV resistance mutations. In the genotyping-based model, only total number of PI resistance mutations was associated with our outcome. In conclusion, the prevalence of DRV mutations was low. Time of HIV infection, use of amprenavir and total number of PI resistance mutations were associated with having more DRV mutations.

    Purpose Aims of this study were to identify aspects of functioning and health relevant to patients with vertigo expressed by ICF categories and to explore the potential of the ICF to describe the patient perspective in vertigo. Methods We conducted a series of qualitative semi-structured face-to-face interviews using a descriptive approach. Data was analyzed using the meaning condensation procedure and then linked to categories of the International Classification of Functioning, Disability and Health (ICF). Results From May to July 2010 12 interviews were carried out until saturation was reached. Four hundred and seventy-one single concepts were extracted which were linked to 142 different ICF categories. 40 of those belonged to the component body functions, 62 to the component activity and participation, and 40 to the component environmental factors. Besides the most prominent aspect “dizziness” most participants reported problems within “Emotional functions (b152), problems related to mobility and carrying out the daily routine. Almost all participants reported “Immediate family (e310)” as a relevant modifying environmental factor. Conclusions From the patients’ perspective, vertigo has impact on multifaceted aspects of functioning and disability, mainly body functions and activities and participation. Modifying contextual factors have to be taken into account to cover the complex interaction between the health condition of vertigo on the individuals’ daily life. The results of this study will contribute to developing standards for the measurement of functioning, disability and health relevant for patients suffering from vertigo. PMID:22738067

    HIV/AIDS is highly prevalent in sub-Saharan Africa and few studies had looked at physically and mentally challenged people living with HIV/AIDS (PLHIV) in this environment. This study aimed to describe the socio-demographic characteristics and challenges faced by these patients attending University College Hospital, Ibadan. A descriptive cross-sectional study design was done. A semi-structured interviewer administered questionnaire was administered to consecutive disabled PLHIV over a period of six months. Data obtained were analyzed using descriptive and inferential statistics. A total of ninety-nine patients were seen during the study period. The mean age of these patients was 39.9 +/- 9.4 years (range 23-60 years). There were 30 (30.3%) males and 69 (69.7%) females. Twenty-four percent had no formal education while 12% had tertiary education. All respondents had suffered stigmatization/discrimination while most were poor. Eighty-seven percent had AIDS at presentation. Musculoskeletal impairments (46.5%), hearing loss (16.2%) and visual impairment (31.3%) were the commonest disability. Over twenty-three percent had prior history of road traffic accident as the cause of disability. Physically and mentally challenged people living with HIV/AIDS are poor and highly stigmatized. They require special assistance to cope and need economic empowerment to reduce their poverty level.

    This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group. Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011. Information extracted from case note review was used to grade patients using the Auckland Regional Grading Criteria. A total of 799 patients were included. The commonest symptoms were: rectal bleeding (25.5-42.3%) and change in bowel habit (20.6-26.8%). Low-risk symptoms including abdominal pain (16.3-46.8%) and weight loss (18.4-26.1%) were not uncommon. 64.4% of Maori and 64.9% of Pacific patients had stage III or IV cancers. Pacific patients had more stage IV disease, 37.7% (pAuckland Regional Grading Criteria would miss 24.7% of the patients with CRC in the referral population. While rectal bleeding and change in bowel habit are frequent presenting symptoms, low-risk atypical symptoms including constipation, weight loss and abdominal pain were not uncommon. Significant proportion of Pacific patients present with late-stage disease. The current Auckland Regional grading criteria would miss significant proportion of our study population with colorectal cancer.

    The aim of this work is to provide an in-depth investigation of the impact of low-grade gliomas (LGG) and their surgery on patients' cognitive and emotional functioning and well-being, carried out via a comprehensive and multiple-measure psychological and neuropsychological assessment. Fifty surgically treated patients with LGG were evaluated 40 months after surgery on their functioning over 6 different cognitive domains, 3 core affective/emotional aspects, and 3 different psychological well-being measures to obtain a clearer picture of the long-term impact of illness and surgery on their psychological and relational world. Close relatives were also involved to obtain an independent measure of the psychological dimensions investigated. Cognitive status was satisfactory, with only mild short-term memory difficulties. The affective and well-being profile was characterized by mild signs of depression, good satisfaction with life and psychological well-being, and good personality development, with patients perceiving themselves as stronger and better persons after illness. However, patients showed higher emotional reactivity, and psychological well-being measures were negatively affected by epileptic burden. Well-being was related to positive affective/emotional functioning and unrelated to cognitive functioning. Good agreement between patients and relatives was found. In the long-term, patients operated on for LGG showed good cognitive functioning, with no significant long-term cognitive sequelae for the extensive surgical approach. Psychologically, patients appear to experience a deep psychological change and maturation, closely resembling that of so-called posttraumatic growth, which, to our knowledge, is for the first time described and quantified in patients with LGG.

    To evaluate a nomogram using the RENAL Nephrometry Score (RENAL-NS) that was developed to characterize masses as benign vs. malignant and high vs. low grade in our patients with small renal masses treated with partial nephrectomy (PN). The nomogram was previously developed and validated in patients with widely variable tumor sizes. Retrospective review of PN performed between 1/2003 and 7/2011. Imaging was reviewed by a urologic surgeon for RENAL-NS. Final pathology was used to classify tumors as benign or malignant and low (I/II) or high (III/IV) Fuhrman grade. Patient age, gender, and RENAL score were entered into the nomogram described by Kutikov et al. to determine probabilities of cancer and high-grade disease. Area under the curve was determined to assess agreement between observed and expected outcomes for prediction of benign vs. malignant disease and for prediction of high- vs. low-grade or benign disease. A total of 250 patients with 252 masses underwent PN during the study period; 179/250 (71.6%) had preoperative imaging available. RENAL-NS was assigned to 181 masses. Twenty-two percent of tumors were benign. Eighteen percent of tumors were high grade. Area under the curve was 0.648 for predicting benign vs. malignant disease and 0.955 for predicting low-grade or benign vs. high-grade disease. The RENAL-NS score nomogram by Kutikov does not discriminate well between benign and malignant disease for small renal masses. The nomogram may potentially be useful in identifying high-grade tumors. Further validation is required where the nomogram probability and final pathologic specimen are available. Copyright © 2014 Elsevier Inc. All rights reserved.

    To analyse the various types of retinopathy in individuals with type 2 DM. Design: Descriptive study. Place and duration of study: Military Hospital Rawalpindi from January 2010 to July 2010 Methods: One hundred and fifty patients with type 2 DM were studied into for different types of retinopathy, based on history, clinical examination (ophthalmological) and laboratory investigations. Results: Out of 150 patients who fulfilled the criteria for study, 93(62%) were male and 57(38%) were female patients, frequency of retinopathy was 28.67%. The duration of diabetes ranged from 5 to 30 years. The frequency of retinopathy was higher in males as compared to females. The mean age of the patients was 51.10 +- 8.33 years with range 36-77 years. Proliferative retinopathy was seen more in those diabetic patients whose duration of disease was more than 10 years. They also showed poor glycaemic control in the form of raised blood glucose and HbA1C levels. Conclusion: About twenty eight percent of our diabetic patients are suffering from diabetic retinopathy. This can be controlled by early detection and effective treatment both in terms of strict glycemic control and laser photocoagulation, thus decreasing the morbidity and mortality due to this chronic disease.

    As the efficacy of all pediatric high-grade glioma (HGG) treatments is similar and still disappointing, it is essential to also investigate the toxicity of available treatments. Prospectively recorded hematologic and nonhematologic toxicities of children treated with radiochemotherapy in the HIT GBM-C/D and HIT-HGG-2007 trials were compared. Children aged 3-18 years with histologically proven HGG (WHO grade III and IV tumors) or unequivocal radiologic diagnosis of diffuse intrinsic pontine glioma (DIPG) were included in these trials. The HIT-HGG-2007 protocol comprised concomitant radiochemotherapy with temozolomide, while cisplatinum/etoposide (PE) and PE plus ifosfamide (PEI) in combination with weekly vincristine injections were applied during radiochemotherapy in the HIT GBM-C/D protocol. Regular blood counts and information about cellular nadirs were available from 304 patients (leukocytes) and 306 patients (thrombocytes), respectively. Grade 3-4 leukopenia was much more frequent in the HIT GBM-C/D cohort (n = 88, 52%) vs. HIT-HGG-2007 (n = 13, 10%; P <0.001). Grade 3-4 thrombopenia was also more likely in the HIT GBM-C/D cohort (n = 21, 12% vs. n = 3,2%; P <0.001). Grade 3-4 leukopenia appeared more often in children aged 3-7 years (n = 38/85, 45%) than in children aged 8-12 years (n = 39/120, 33%) and 13-18 years (24/100, 24%; P =0.034). In addition, sickness was more frequent in the HIT GBM-C/D cohort (grade 1-2: 44%, grade 3-4: 6% vs. grade 1-2: 28%, grade 3-4: 1%; P <0.001). Radiochemotherapy involving cisplatinum-based polychemotherapy is more toxic than radiotherapy in combination with temozolomide. Without evidence of differences in therapeutic efficacy, the treatment with lower toxicity, i. e., radiotherapy with temozolomide should be used. (orig.) [de

    Diagnostic imaging is pivotal in the initial detection, characterization, staging and post-treatment follow-up of patients with high-grade osteogenic and Ewing's sarcoma. In the present review article, conventional and new imaging modalities are discussed with regard to the monitoring of the effect of neoadjuvant chemotherapy in such patients. Presurgical monitoring of response to chemotherapy may have an impact on modification of neoadjuvant treatment protocols, on patient selection for the performance and timing of limb-salvage surgery and on planning of radiation therapy (in non-operated Ewing's sarcomas) and selection of postoperative chemotherapy regimens. Dynamic contrast-enhanced MR imaging, as part of a routine MR protocol, assists in the detection of the most viable parts of the tumour and serves as an initial standard for follow-up of the metabolic activity of the tumour during and after chemotherapy, both in small intraosseous tumours and in tumours with an associated soft tissue mass. In combination with selected morphological features, dynamic imaging parameters are therefore advocated for monitoring the effect of neoadjuvant chemotherapy in patients with osteogenic and Ewing's sarcoma.

    Purpose: To prospectively evaluate outcome and toxicity after carbon ion radiotherapy (RT) in chordomas and low-grade chondrosarcomas. Patients and Methods: Between September 1998 and December 2001, 74 patients were treated for chordomas and chondrosarcomas with carbon ion RT at the ''Gesellschaft fuer Schwerionenforschung'' (GSI). Seven patients reirradiated with reduced carbon ion doses after conventional RT were excluded from the analysis, leaving 67 evaluable patients (44 chordomas and 23 chondrosarcomas) who received a full course of carbon ion therapy. Tumor-conform application of carbon ion beams was realized by intensity-controlled raster scanning with active energy variation. Three-dimensional treatment planning included intensity modulation and biological plan optimization. A median dose of 60 GyE was applied to the target volume within 20 consecutive days at a dose of 3.0 GyE per fraction. Results: Median follow-up was 15 months (range 3-46 months). At 3 years, actuarial local control was 100% for chondrosarcomas and 87% for chordomas, respectively. Partial tumor remission was observed in 14/44 (31%) chordoma patients and in 4/23 (17%) chondrosarcoma patients. At 3 years, actuarial overall survival was 100% for chondrosarcomas and 89% for chordomas, respectively. No severe side effects > CTC III have been observed. Conclusions: These data demonstrate the clinical efficiency and safety of scanning beam delivery of carbon ion beams in patients with skull base chordomas and chondrosarcomas. The observation of tumor regressions at a dose level of 60 GyE may indicate that the biological effectiveness of carbon ions in chordomas and chondrosarcomas is higher than initially estimated.

    Purpose: Most analyses of the effect of patient and tumor characteristics on long-term outcome in breast cancer use the Cox proportional hazard (prohaz) model, which assumes that hazard rates for any two subsets are proportional (i.e., hazard ratios are constant) over time. We examined whether this assumption is correct for predicting time to distant failure in breast cancer patients treated with breast-conserving therapy and speculated on the biologic implications of these findings. Materials and Methods: Between 1968 and 1986, 1081 patients treated for clinical stage I or II invasive breast cancer with a complete gross excision and ≥60 Gy to the tumor bed had pure infiltrating ductal carcinoma on central pathologic review. 37 patients (3%) were lost to followup after 7-181 months. Median followup for 694 survivors was 12 years (8-23 yrs.). Time to distant failure was defined to be time to regional nodal failure or distant metastases and was not censored for local recurrence, contralateral breast cancer, or death from other causes. We evaluated the following characteristics: histologic grade (modified Bloom-Richardson, 219 grade I, 482 grade II, 380 grade III), estrogen receptor (252 ER neg, 386 ER pos, 443 ER unk), positive axillary nodes (0,1-3,≥4, no axillary dissection in 214), adjuvant chemotherapy (in 291 patients), T stage, lymphatic vessel invasion, mononuclear cell response, clinical size in mm, age at diagnosis, and necrosis. Results: A stepwise prohaz model found all the above characteristics except the last three to be significant (all p 0 (i.e., grade III has a larger risk) but for following years, the log hazard ratio is < 0 (i.e., grade II has a large risk; see Figure for estimated log hazard ratio and 95% CI). The test for non-proportionality of grade II vs. grade I (p=0.08) and ER positive vs negative (p=0.06) were suggestive but the log hazard ratios never cross 0 (i.e., no reversal of direction of risk). Conclusions: Tumor grade clearly

    Patellofemoral instability is one of the most common causes of cartilage damage in teenagers. To quantitatively evaluate the patellar cartilage in patients with patellofemoral instability using T2 relaxation time maps (T2 maps), compare the values to those in patients without patellofemoral instability and correlate them with morphological grades in patients with patellofemoral instability. Fifty-three patients with patellofemoral instability (mean age: 15.9 ± 2.4 years) and 53 age- and gender-matched patients without patellofemoral instability were included. Knee MR with axial T2 map was performed. Mean T2 relaxation times were obtained at the medial, central and lateral zones of the patellar cartilage and compared between the two groups. In the patellofemoral instability group, morphological grading of the patellar cartilage (0-4) was performed and correlated with T2 relaxation times. Mean T2 relaxation times were significantly longer in the group with patellofemoral instability as compared to those of the control group across the patellar cartilage (Student's t-test, P<0.05) with the longest time at the central area. Positive correlation was seen between mean T2 relaxation time and morphological grading (Pearson correlation coefficiency, P<0.001). T2 increased with severity of morphological grading from 0 to 3 (mixed model, P<0.001), but no statistical difference was seen between grades 3 and 4. In patellofemoral instability, patellar cartilage damage occurs across the entire cartilage with the highest T2 values at the apex. T2 relaxation times directly reflect the severity in low-grade cartilage damage, which implies an important role for T2 maps in differentiating between normal and low-grade cartilage damage. (orig.)

    Impaired fasting glucose (IFG) is associated with an increased risk of cardiovascular disease but the underlying mechanisms are still unclear. Aim of the study was to investigate the interplay between platelet activation, lipopolysaccharides (LPS) and markers of oxidative stress in patients with IFG and control subjects. We performed a cross-sectional study including 35 patients with IFG and 35 control subjects who were well comparable for age, sex, body mass index and smoking history. Serum levels of LPS, zonulin (a marker of gut permeability), oxidized LDL and plasma levels of soluble P-selectin, were measured. Patients with IFG had significantly higher levels of sP-selectin, LPS, zonulin and oxLDL compared to control subjects. The IFG status (beta coefficient: 0.518, p zonulin (r = 0.521, p = 0.001); this association was confirmed at multivariable analysis (beta coefficient: 0.512, p = 0.007). Our study provides evidence that patients with IFG have increased platelet activation, and suggests LPS as a potential trigger for in vivo platelet activation in this patient population.

    Eating behavior style (emotional, restrictive, or external) has been proposed as an explanation for the differences in response to food-related cues between people who overeat and those who do not, and has been also considered a target for the treatment of eating disorders (EDs) characterized by lack of control over eating and weight-related (overweight/obesity) conditions. The aim of this study was to analyze the relationship between eating behavior style and psychophysiological responses (self-reported food craving and anxiety) to food-related virtual reality (VR) environments in outpatients with bulimia nervosa (BN) and binge eating disorder (BED) and to compare them with healthy participants. Fifty-eight outpatients and 135 healthy participants were exposed to palatable foods in four experimental everyday real-life VR environments (kitchen, dining room, bedroom and café). During exposure, cue-elicited food craving and anxiety were assessed. Participants also completed standardized instruments for the study purposes. ED patients reported significantly higher levels of craving and anxiety when exposed to the virtual food than healthy controls. Eating behavior styles showed strong associations with cue-elicited food craving and anxiety. In the healthy group, external eating was the only predictor of cue-elicited craving and anxiety. In participants with BN and BED, external and emotional eating were the best predictors of cue-elicited craving and anxiety, respectively. Copyright © 2017 Elsevier Ltd. All rights reserved.

  1. Advanced magnetic resonance imaging methods for planning and monitoring radiation therapy in patients with high-grade glioma.

    2014-10-01

    This review explores how the integration of advanced imaging methods with high-quality anatomical images significantly improves the characterization, target definition, assessment of response to therapy, and overall management of patients with high-grade glioma. Metrics derived from diffusion-, perfusion-, and susceptibility-weighted magnetic resonance imaging in conjunction with magnetic resonance spectroscopic imaging, allows us to characterize regions of edema, hypoxia, increased cellularity, and necrosis within heterogeneous tumor and surrounding brain tissue. Quantification of such measures may provide a more reliable initial representation of tumor delineation and response to therapy than changes in the contrast-enhancing or T2 lesion alone and have a significant effect on targeting resection, planning radiation, and assessing treatment effectiveness. In the long term, implementation of these imaging methodologies can also aid in the identification of recurrent tumor and its differentiation from treatment-related confounds and facilitate the detection of radiationinduced vascular injury in otherwise normal-appearing brain tissue.

    Advances in molecular profiling have facilitated the emergence of newly defined entities of central nervous system tumor, including CNS high-grade neuroepithelial tumor with BCOR alteration (CNS HGNET-BCOR). Relatively little is known about the clinical behaviour of these newly-characterized tumors. We describe a pediatric male patient with CNS HGNET-BCOR who developed seeding of the tumor into the site of the surgical wound within months of surgery for resection of a residual posterior fossa tumor. This case emphasises three important points. First, CNS HGNET-BCOR can be aggressive tumors that necessitate close clinical and radiological surveillance. Second, surveillance imaging in such cases should incorporate the surgical incision site into the field of view, and this should be closely scrutinised to ensure the timely detection of wound site seeding. Third, wound site seeding may still occur despite the use of meticulous surgical techniques. Copyright © 2018. Published by Elsevier Inc.

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 resistance to protease inhibitors (PI results from mutations in the viral protease (PR that reduce PI binding but also decrease viral replicative capacity (RC. Additional mutations compensating for the RC loss subsequently accumulate within PR and in Gag substrate cleavage sites. We examined the respective contribution of mutations in PR and Gag to PI resistance and RC and their interdependence using a panel of HIV-1 molecular clones carrying different sequences from six patients who had failed multiple lines of treatment. Mutations in Gag strongly and directly contributed to PI resistance besides compensating for fitness loss. This effect was essentially carried by the C-terminal region of Gag (containing NC-SP2-p6 with little or no contribution from MA, CA, and SP1. The effect of Gag on resistance depended on the presence of cleavage site mutations A431V or I437V in NC-SP2-p6 and correlated with processing of the NC/SP2 cleavage site. By contrast, reverting the A431V or I437V mutation in these highly evolved sequences had little effect on RC. Mutations in the NC-SP2-p6 region of Gag can be dually selected as compensatory and as direct PI resistance mutations, with cleavage at the NC-SP2 site behaving as a rate-limiting step in PI resistance. Further compensatory mutations render viral RC independent of the A431V or I437V mutations while their effect on resistance persists.

    Purpose: The diagnosis-specific Graded Prognostic Assessment (GPA) was published to clarify prognosis for patients with brain metastases. This study refines the existing Breast-GPA by analyzing a larger cohort and tumor subtype. Methods and Materials: A multi-institutional retrospective database of 400 breast cancer patients treated for newly diagnosed brain metastases was generated. Prognostic factors significant for survival were analyzed by multivariate Cox regression and recursive partitioning analysis (RPA). Factors were weighted by the magnitude of their regression coefficients to define the GPA index. Results: Significant prognostic factors by multivariate Cox regression and RPA were Karnofsky performance status (KPS), HER2, ER/PR status, and the interaction between ER/PR and HER2. RPA showed age was significant for patients with KPS 60 to 80. The median survival time (MST) overall was 13.8 months, and for GPA scores of 0 to 1.0, 1.5 to 2.0, 2.5 to 3.0, and 3.5 to 4.0 were 3.4 (n = 23), 7.7 (n = 104), 15.1 (n = 140), and 25.3 (n = 133) months, respectively (p < 0.0001). Among HER2-negative patients, being ER/PR positive improved MST from 6.4 to 9.7 months, whereas in HER2-positive patients, being ER/PR positive improved MST from 17.9 to 20.7 months. The log-rank statistic (predictive power) was 110 for the Breast-GPA vs. 55 for tumor subtype. Conclusions: The Breast-GPA documents wide variation in prognosis and shows clear separation between subgroups of patients with breast cancer and brain metastases. This tool will aid clinical decision making and stratification in clinical trials. These data confirm the effect of tumor subtype on survival and show the Breast-GPA offers significantly more predictive power than the tumor subtype alone.

    Pressure ulcers are a costly hospital-acquired condition in terms of clinical outcome and expense. The Braden Scale was developed in 1987 as a risk scoring method for pressure ulcers and uses six different risk factors: sensory perception, moisture, activity, mobility, nutrition, and friction and shear. A score of ≤18 is considered high risk. To date, research on the utility of the Braden Scale has focused on general medicine and nontrauma/burn surgery patients. We hypothesize that the Braden Scale does not accurately discriminate who will get a pressure ulcer among trauma and burn patients. We collected data from medical records regarding documented Braden scores and presence of pressure ulcers regardless of staging. Patients with ulcers present on admission were excluded from analysis. For each patient, the lowest Braden score documented before the occurrence of the pressure ulcer was determined. A logistic regression was used to estimate odds ratios and associated 95% confidence intervals for the association between pressure ulcer likelihood and lowest Braden Scale measurement. To determine the discriminatory ability of the Braden Scale on pressure ulcer risk, four measures of performance (i.e., sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio) were calculated for four nonmutually exclusive groups: a Braden Scale measurement ≤18, ≤14, ≤12, and ≤9. From 2011 through 2014, a total of 2660 patients were admitted to the trauma/burn intensive care unit. Of these patients, 63 (2.3%) subsequently developed a pressure ulcer. A Braden Scale of ≤18 as the threshold for being at-risk of pressure ulcer had a sensitivity of 100% and specificity of 6%, whereas a Braden Scale of ≤9 had a sensitivity of 28.6% and a specificity of 90%. For all Braden Scale measurements, the positive likelihood ratio never reached the value of 10 that suggests high likelihood of an ulcer. The Braden scale has mediocre discriminatory ability among

    The aim of this study was to assess whether the symptom severity and health-related quality of life (HRQL) of patients with dysphagia and esophageal eosinophilia correlate with disease activity as expressed by the number of eosinophils in the esophageal mucosa. This study included newly diagnosed (n = 58) or relapsed patients (n = 7), where 40% were diagnosed in connection with esophageal bolus impaction. The mean age was 45 years (19-88), and 74% were men. Symptoms and HRQL were recorded using the Watson Dysphagia Scale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Oesophageal Module 18 and the Short Form-36 Questionnaire. Histological samples gathered from the proximal and distal esophageal mucosa were stained using both hematoxylin and eosin (HE) and an immunohistochemical (IHC) technique against 'Eosinophil Major Basic Protein,' and the peak number of eosinophils per high-power field was assessed. More eosinophils were detected after IHC staining than HE staining (P < 0.001). No correlation was found between symptoms or the HRQL and the number of eosinophils. However, higher numbers of eosinophils at the proximal esophagus were found in patients with concomitant bolus impaction (IHC P < 0.05 and HE P < 0.05) and could serve as a risk marker. © 2015 International Society for Diseases of the Esophagus.

  13. Right inferior frontal gyrus activation is associated with memory improvement in patients with left frontal low-grade glioma resection.

    Full Text Available Patients with low-grade glioma (LGG have been studied as a model of functional brain reorganization due to their slow-growing nature. However, there is no information regarding which brain areas are involved during verbal memory encoding after extensive left frontal LGG resection. In addition, it remains unknown whether these patients can improve their memory performance after instructions to apply efficient strategies. The neural correlates of verbal memory encoding were investigated in patients who had undergone extensive left frontal lobe (LFL LGG resections and healthy controls using fMRI both before and after directed instructions were given for semantic organizational strategies. Participants were scanned during the encoding of word lists under three different conditions before and after a brief period of practice. The conditions included semantically unrelated (UR, related-non-structured (RNS, and related-structured words (RS, allowing for different levels of semantic organization. All participants improved on memory recall and semantic strategy application after the instructions for the RNS condition. Healthy subjects showed increased activation in the left inferior frontal gyrus (IFG and middle frontal gyrus (MFG during encoding for the RNS condition after the instructions. Patients with LFL excisions demonstrated increased activation in the right IFG for the RNS condition after instructions were given for the semantic strategies. Despite extensive damage in relevant areas that support verbal memory encoding and semantic strategy applications, patients that had undergone resections for LFL tumor could recruit the right-sided contralateral homologous areas after instructions were given and semantic strategies were practiced. These results provide insights into changes in brain activation areas typically implicated in verbal memory encoding and semantic processing.

    2017-04-01

    Surgical indication for acromioclavicular joint (ACJ) injuries still represents a reason for shoulder and trauma debate. In high-grade injuries, surgery is advocated because some of the non-operatively managed patients may have persistent shoulder pain that could make them unable to return to their previous activity. It has been shown that many of the patients with high-grade ACJ injuries that are managed non-operatively involve the development of scapular dyskinesis, situation that may result in loss of strength and weakness. On the other side, it has been widely reported that the period while the hook plate is present involves functional limitations and pain. The purpose of this study was to compare the quality of life (QoL) of patients with acute high-grade ACJ injuries (Rockwood grade III-V), managed operatively with a hook plate versus the QoL of patients managed non-operatively, 24 months or more after shoulder injury. Patients with acute high-grade ACJ injuries managed operatively (hook plate) or non-operatively, between 2008 and 2012 were included. The QoL was evaluated by means of the Health Survey questionnaire (SF36), the Visual Analogue Scale (VAS) for pain, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, the Constant score and the Global Satisfaction (scale from 0 to 10) assessed at the last follow-up visit. The presence of scapular dyskinesis was assessed. Comparison between groups was made. Thirty-two patients were included: 11 hook plate-group (PLATE group) (5 Rockwood III and 6 V) and 21 conservative-group (CONS group) (4 Rockwood III and 17 V). The mean age was 41 [19-55] years old for the PLATE group and 38 [19-55] for the CONS group (p = 0.513). The mean follow-up was 32.50 ± 11.64 months for the PLATE group and 34.77 ± 21.98 months for the CONS group (p = 0.762). The mean results of the questionnaires assessed at the last follow-up visit were: (1) physical SF36 score (PLATE group 53.70 ± 4.33 and CONS group

    The impact of survival is determined by the incorporation of the chemotherapeutic temozolamide into the therapy regimen of patients with high grade gliomas. Overall survival is determined in patients with high grade gliomas. The investigation is performed with the total of patients with high grade gliomas, with treatment of radiotherapy and temozolamide. Progression-free survival is determined in the population with high-grade gliomas at Hospital Mexico, from January 2009 to December 2011. The diagnosis of glioblastoma is given in 86% and astrocytoma grade III in 14% of the cases. The concomitance of radiotherapy with temozolomide is received by 33 of 37 patients. Seventy-six percent of patients completed the 6 cycles of adjuvant therapy. The overall survival rate was 14.39 months. Patients with grade III gliomas have had a better prognosis [es

    Grade IV vestibular schwannoma (Koos classification) is generally considered to be an indication for microsurgical resection or combined radiosurgery-microsurgery. However, the place of Gamma Knife stereotactic surgery (GK-SRS), either as first-line treatment or when progression of residual tumor compresses the brainstem, has not been clearly evaluated. This article reports the results of a large case series of patients with grade 4 vestibular schwannoma treated by GK-SRS. All consecutive patients with grade IV vestibular schwannoma treated by GK-SRS in our department between 1996 and 2011 with a minimum follow-up of 3 years were included in this study. 86 patients were treated by GK-SRS with a minimum follow-up of 3 years. Mean follow-up was 6.2 years (3-16 years). The mean age of the patients at the time of GK-SRS was 54.6 years (range: 23-84) and the sex ratio was 0.6. At the time of radiosurgery, no patient presented brainstem dysfunction prior to GK-SRS. 38 patients had functional hearing before treatment. One patient presented mild trigeminal neuralgia before GK-SRS. Tumor control with no clinical deterioration was obtained in 78 patients (90.7%). No radiation-induced brainstem or cranial nerve toxicity was observed in any of these patients. Functional hearing was maintained in 25 patients. 8 (9.3%) patients presented tumor growth and required microsurgical resection in 7 cases and ventricular shunt in 1 case. On the basis of this large series, GK-SRS appears to be a safe and effective treatment option for grade IV vestibular schwannoma for patients with no signs of brainstem dysfunction.

    1989-11-01

    Serum thyroid hormone and basal and post TRH stimulated levels of TSH were measured in 48 female subjects of mean age 29.3 ± 9.2 and mean gravida 2.9 ± 2.6 with trophoblastic disease (TD), both benign and malignant. Normal pregnant women (n=21) served as controls. Twenty-five patients showed a normal response to TRH (Group i) while the rest (Group ii) had subnormal response while thyroid hormone levels were increased. Two subgroups iiA and iiB were formed within Group ii on the basis of the free T 4 levels (measured by equilibrium dialysis) falling below or above the 25th percentile. hCG levels were higher in Group ii than in Group i and a stepwise significant increase in the mean level of this hormone was observed in Group i to iiA and iiB. Significant correlation between hCG levels and those of thyroxine, free thyroxine, and triiodothyronine were found in TD patients as a whole, but not within the different subgroups. Clinical signs were minimal, with proximal muscle weakness and fine finger tumours observed in 10 patients in Group iiB. The study shows that the incidence of biochemical hyperthyroidism is higher than was reported before sensitive methods for TSH measurement were available, and postulates that increased hCG concentrations in themselves and/or abnormal metabolic variants of hCG produced by trophoblastic tumours may act as thyroid stimulators in this condition. 64 refs, 5 figs, 4 tabs

    Highlights: • Parotid glands at grade 0–3 had significant values from those in healthy glands. • Parotid D and f values were correlated with MR nodule grade significantly. • There were significant differences of D, f, and D * values among glands at grade 0–3. - Abstract: Purpose: To explore the correlation between intravoxel incoherent motion (IVIM) magnetic resonance (MR) parameters and MR nodular grade of parotid glands in patients with Sjögren’s syndrome (SS). Materials and methods: A total of 31 consecutive patients with SS and 28 gender- and age-matched healthy volunteers underwent bilateral parotid 3.0T MR examination including the IVIM sequence (9 b values, 0–800 s/mm 2 ). The apparent diffusion coefficient (ADC), diffusion coefficient D, pseudo-diffusion coefficient D * , and perfusion fraction f of bilateral parotid glands were obtained, and the nodular grade of each parotid gland was evaluated according to the MR morphological appearance. Results: Sixty-two parotid glands in 31 patients with SS consisted of 32, 14, 8, and 8 parotid glands at MR nodular grades 0, 1, 2, and 3, respectively. In parotid glands of grade 0, 1, 2, 3 and healthy volunteers, the ADC values were (1.13 ± 0.25, 1.11 ± 0.17, 1.05 ± 0.24, 0.89 ± 0.04 and 1.00 ± 0.21) × 10 −3 mm 2 /s, D values were (0.92 ± 0.13, 0.90 ± 0.19, 0.90 ± 0.03, 0.67 ± 0.03, 0.81 ± 0.03) × 10 −3 mm 2 /s, f values were 0.20 ± 0.04, 0.18 ± 0.02, 0.15 ± 0.01, 0.11 ± 0.01, 0.15 ± 0.06, and D * values were (53.89 ± 28.26, 41.78 ± 16.35, 51.24 ± 18.69, 31.83 ± 18.03, 36.83 ± 16.14) × 10 −3 mm 2 /s respectively. The ADC, D, f, and D * values of parotid glands in patients with SS at grade 0 were significantly higher than those in healthy volunteers (all P < 0.05).

    Highlights: • Parotid glands at grade 0–3 had significant values from those in healthy glands. • Parotid D and f values were correlated with MR nodule grade significantly. • There were significant differences of D, f, and D{sup *} values among glands at grade 0–3. - Abstract: Purpose: To explore the correlation between intravoxel incoherent motion (IVIM) magnetic resonance (MR) parameters and MR nodular grade of parotid glands in patients with Sjögren’s syndrome (SS). Materials and methods: A total of 31 consecutive patients with SS and 28 gender- and age-matched healthy volunteers underwent bilateral parotid 3.0T MR examination including the IVIM sequence (9 b values, 0–800 s/mm{sup 2}). The apparent diffusion coefficient (ADC), diffusion coefficient D, pseudo-diffusion coefficient D{sup *}, and perfusion fraction f of bilateral parotid glands were obtained, and the nodular grade of each parotid gland was evaluated according to the MR morphological appearance.

    Glioblastomas progress rapidly making response evaluation using MRI insufficient since treatment effects are not detectable until months after initiation of treatment. Thus, there is a strong need for supplementary biomarkers that could provide reliable and early assessment of treatment efficacy. Analysis of alterations in the metabolome may be a source for identification of new biomarker patterns harboring predictive information. Ideally, the biomarkers should be found within an easily accessible compartment such as the blood. Using gas-chromatographic- time-of-flight-mass spectroscopy we have analyzed serum samples from 11 patients with glioblastoma during the initial phase of radiotherapy. Fasting serum samples were collected at admittance, on the same day as, but before first treatment and in the morning after the second and fifth dose of radiation. The acquired data was analyzed and evaluated by chemometrics based bioinformatics methods. Our findings were compared and discussed in relation to previous data from microdialysis in tumor tissue, i.e. the extracellular compartment, from the same patients. We found a significant change in metabolite pattern in serum comparing samples taken before radiotherapy to samples taken during early radiotherapy. In all, 68 metabolites were lowered in concentration following treatment while 16 metabolites were elevated in concentration. All detected and identified amino acids and fatty acids together with myo-inositol, creatinine, and urea were among the metabolites that decreased in concentration during treatment, while citric acid was among the metabolites that increased in concentration. Furthermore, when comparing results from the serum analysis with findings in tumor extracellular fluid we found a common change in metabolite patterns in both compartments on an individual patient level. On an individual metabolite level similar changes in ornithine, tyrosine and urea were detected. However, in serum, glutamine and

    Patellofemoral instability is one of the most common causes of cartilage damage in teenagers. To quantitatively evaluate the patellar cartilage in patients with patellofemoral instability using T2 relaxation time maps (T2 maps), compare the values to those in patients without patellofemoral instability and correlate them with morphological grades in patients with patellofemoral instability. Fifty-three patients with patellofemoral instability (mean age: 15.9 ± 2.4 years) and 53 age- and gender-matched patients without patellofemoral instability were included. Knee MR with axial T2 map was performed. Mean T2 relaxation times were obtained at the medial, central and lateral zones of the patellar cartilage and compared between the two groups. In the patellofemoral instability group, morphological grading of the patellar cartilage (0-4) was performed and correlated with T2 relaxation times. Mean T2 relaxation times were significantly longer in the group with patellofemoral instability as compared to those of the control group across the patellar cartilage (Student's t-test, Ppatellofemoral instability, patellar cartilage damage occurs across the entire cartilage with the highest T2 values at the apex. T2 relaxation times directly reflect the severity in low-grade cartilage damage, which implies an important role for T2 maps in differentiating between normal and low-grade cartilage damage.

    Deregulation of multiple DNA repair pathways may contribute to aggressive biology and therapy resistance in gliomas. We evaluated transcript levels of 157 genes involved in DNA repair in an adult glioblastoma Test set (n=191) and validated in ‘The Cancer Genome Atlas’ (TCGA) cohort (n=508). A DNA repair prognostic index model was generated. Artificial neural network analysis (ANN) was conducted to investigate global gene interactions. Protein expression by immunohistochemistry was conducted in 61 tumours. A fourteen DNA repair gene expression panel was associated with poor survival in Test and TCGA cohorts. A Cox multivariate model revealed APE1, NBN, PMS2, MGMT and PTEN as independently associated with poor prognosis. A DNA repair prognostic index incorporating APE1, NBN, PMS2, MGMT and PTEN stratified patients in to three prognostic sub-groups with worsening survival. APE1, NBN, PMS2, MGMT and PTEN also have predictive significance in patients who received chemotherapy and/or radiotherapy. ANN analysis of APE1, NBN, PMS2, MGMT and PTEN revealed interactions with genes involved in transcription, hypoxia and metabolic regulation. At the protein level, low APE1 and low PTEN remain associated with poor prognosis. In conclusion, multiple DNA repair pathways operate to influence biology and clinical outcomes in adult high grade gliomas. PMID:25026297

    Advanced radioactive refractory and progressive or symptomatic differentiated thyroid carcinoma (DTC) is a rare condition. Sorafenib was recently approved for the treatment of these patients. We present the case of a 67 year old woman diagnosed with DTC who underwent a total thyroidectomy with central, lateral-compartment neck dissection and shaving of the trachea and esophagus due to tumor infiltration. A local recurrence was detected 14 months later requiring, additionally, two tracheal rings resection. The patient received a cumulative {sup 131}I dose of 650 mCi and developed dysphagia and dyspnea 63 months after initial surgery. A {sup 18}FGD-PET/CT showed progression of the local mass associated to hypermetabolic pulmonary nodules. Sorafenib 800 mg/day was then prescribed. A dose reduction to 400 mg/day was necessary due to grade 3 thrombocytopenia that appeared four months after drug prescription. Platelet count went to normal after this dose reduction. Five months after initiation of sorafenib, a partial response of the local mass with significant intra-tumoral necrosis was observed. We conclude that sorafenib is a valid option for locally advanced DTC and that the platelet count should be evaluated regularly because it seems that thrombocytopenia might be more frequently observed in DTC than in other types of tumors.

    Despite its high prevalence among patients with aneurysmal subarachnoid hemorrhage (aSAH) and high risk of delayed cerebral ischemia (DCI), the Fisher grade 3 category remains a poorly studied subgroup. The aim of this cohort study has been to investigate the prognostic value of the Hijdra sum scoring system for the functional outcome in patients with Fisher grade 3 aSAH, in order to improve the risk stratification within this Fisher category. Initial CT scans of 72 prospectively enrolled patients with Fisher grade 3 aSAH were analyzed, and cisternal, ventricular, and total amount of blood were graded according to the Hijdra scale. Additionally, space-occupying subarachnoid blood clots were assessed. Outcome was evaluated after 6 months. Within the subgroup of Fisher grade 3, aSAH patients with an unfavorable outcome showed a significantly larger cisternal Hijdra sum score (HSS: 21.1 ± 5.2) than patients with a favorable outcome (HSS: 17.6 ± 5.9; p = 0.009). However, both the amount of ventricular blood (p = 0.165) and space-occupying blood clots (p = 0.206) appeared to have no prognostic relevance. After adjusting for the patient's age, gender, tobacco use, clinical status at admission, and presence of intracerebral hemorrhage, the cisternal and total HSS remained the only independent parameters included in multivariate logistic regression models to predict functional outcome (p Fisher 3 category. We suggest that the Hijdra scale is a practically useful prognostic instrument for the risk evaluation after aSAH and should be applied more often in the clinical setting.

    Functional magnetic resonance (fMRI) studies results in case of an adult patient with low grade glioma (LGG) in dominant hemisphere suggest brain plasticity process with acquisition of language functions by the non-dominant hemisphere speech regions. A 36-years old right-handed woman was admitted to the Department of Neurosurgery for surgical treatment of brain tumor. An MRI examination revealed a pathological mass in the left frontal lobe, in close topographical relationship to the Broca’s area. A left fronto-parietal craniotomy was performed, with an intraoperative awake language mapping procedure. A total resection of the pathological mass was achieved. The tumor was examined histologically as LGG. In the follow-up MRI exam 32 months after the operation a tumor recurrence was suggested. The fMRI exams performed preoperative and 3, 32 and 41 months after the operation showed changes in language regions activation patterns, with a progressive right-sided activation of Broca’s and Wernicke’s areas. Pre- and postoperative cognitive evaluation by a neuropsychologist did not detect any language impairment. We present a running process of reorganization of language areas in a patient after brain tumor resection, from strong left-sided to symmetrical lateralization. 1. FMRI results in comparison with the psychological status of the patient proved contribution of functional reorganization to the preservation of language performance. 2. A slow growing LGG as well as the recurrence of the tumor near the left Broca’s area might be the factors leading to reorganization of language-related areas by recruiting the right hemisphe

    Background and Purpose. Low-grade gliomas show infiltrative growth in white matter tracts. Diffusion tensor tractography can noninvasively assess white matter tracts. The aim was to preoperatively assess tumor growth in white matter tracts using quantitative MR tractography (3T). The hypothesis was that suspected infiltrated tracts would have altered diffusional properties in infiltrated tract segments compared to noninfiltrated tracts. Materials and Methods. Forty-eight patients with suspected low-grade glioma were included after written informed consent and underwent preoperative diffusion tensor imaging in this prospective review-board approved study. Major white matter tracts in both hemispheres were tracked, segmented, and visually assessed for tumor involvement in thirty-four patients with gliomas grade II or III (astrocytomas or oligodendrogliomas) on postoperative neuropathological evaluation. Relative fractional anisotropy (rFA) and mean diffusivity (rMD) in tract segments were calculated and compared with visual evaluation and neuropathological diagnosis. Results. Tract segment infiltration on visual evaluation was associated with a lower rFA and high rMD in a majority of evaluated tract segments (89% and 78%, resp.). Grade II and grade III gliomas had similar infiltrating behavior. Conclusion. Quantitative MR tractography corresponds to visual evaluation of suspected tract infiltration. It may be useful for an objective preoperative evaluation of tract segment involvement

    To define the outcomes of arthroscopic correction of femoroacetabular impingement (FAI) based on Tönnis findings within a previously reported patient population, including a comparative analysis of Tönnis grade 0 and 1 versus grade 2 changes. Outcomes (modified Harris Hip Score [mHHS]) of a previously published study of arthroscopic correction of FAI were correlated with Tönnis grade. The inclusion criteria were the first 100 consecutive patients undergoing arthroscopic FAI correction with minimum 2-year follow-up. These procedures were performed between December 2003 and May 2006. Grades were determined independently by 2 experienced clinicians. Tönnis grades 0 and 1 were compared with Tönnis grade 2. Independent variables of sex and age were also evaluated. The average age of the entire group was 34.7 years (range, 13-76 years), with 66 male and 34 female patients. Of the patients, 17 had Tönnis grade 0, 49 had Tönnis grade 1, 29 had Tönnis grade 2, and 4 had Tönnis grade 3 (1 unknown). The average mHHS improvement for Tönnis grade 0 was 20.6 points; Tönnis grade 1, 22.2 points; Tönnis grade 2, 14.9 points; and Tönnis grade 3, 18.8 points. The improvement was statistically (P 8 points) significant across all Tönnis grades. There was no difference (P = .077) between Tönnis grades 0 and 1 (21.8 points) versus grade 2 (14.9 points). There was no difference based on sex or age. These data support that statistically and clinically meaningful successful patient-reported outcomes (mHHS) at 2 years can be encountered even in the presence of Tönnis grade 2 radiographic features. Neither age nor sex was an indicator of poorer results within similar Tönnis grades. Level III, case-control study. Copyright © 2018 Arthroscopy Association of North America.

    Reporting ototoxicity is frequently complicated by use of various ototoxicity criteria. The International Society of Pediatric Oncology (SIOP) ototoxicity grading scale was recently proposed for standardized use in reporting hearing loss outcomes across institutions. The aim of this study was to evaluate the concordance between the Chang and SIOP ototoxicity grading scales. Differences between the two scales were identified and the implications these differences may have in the clinical setting were discussed. Audiological evaluations were reviewed for 379 patients with newly diagnosed medulloblastoma (ages 3-21 years). Each patient was enrolled on one of two St. Jude clinical protocols that included craniospinal radiation therapy and four courses of 75 mg/m(2) cisplatin chemotherapy. The latest audiogram conducted 5.5-24.5 months post-protocol treatment initiation was graded using the Chang and SIOP ototoxicity criteria. Clinically significant hearing loss was defined as Chang grade ≥2a and SIOP ≥2. Hearing loss was considered serious (requiring a hearing aid) at the level of Chang grade ≥2b and SIOP ≥3. A strong concordance was observed between the Chang and SIOP ototoxicity scales (Stuart's tau-c statistic = 0.89, 95% CI: 0.86, 0.91). Among those patients diagnosed with serious hearing loss, the two scales were in good agreement. However, the scales deviated from one another in classifying patients with less serious or no hearing loss. Although discrepancies between the Chang and SIOP ototoxicity scales exist primarily for patients with no or minimal hearing loss, the scales share a strong concordance overall. © 2013 Wiley Periodicals, Inc.

    Purpose: To evaluate, in a pilot study, the phosphorylated H2AX (γH2AX) foci approach for identifying patients with double-strand break (DSB) repair deficiencies, who may overreact to DNA-damaging cancer therapy. Methods and Materials: The DSB repair capacity of children with solid cancers was analyzed compared with that of age-matched control children and correlated with treatment-related normal-tissue responses (n = 47). Double-strand break repair was investigated by counting γH2AX foci in blood lymphocytes at defined time points after irradiation of blood samples. Results: Whereas all healthy control children exhibited proficient DSB repair, 3 children with tumors revealed clearly impaired DSB repair capacities, and 2 of these repair-deficient children developed life-threatening or even lethal normal-tissue toxicities. The underlying mutations affecting regulatory factors involved in DNA repair pathways were identified. Moreover, significant differences in mean DSB repair capacity were observed between children with tumors and control children, suggesting that childhood cancer is based on genetic alterations affecting DSB repair function. Conclusions: Double-strand break repair alteration in children may predispose to cancer formation and may affect children's susceptibility to normal-tissue toxicities. Phosphorylated H2AX analysis of blood samples allows one to detect DSB repair deficiencies and thus enables identification of children at risk for high-grade toxicities.

Methods A retrospective analysis of 226 multiply injured patients with liver or splenic lesions treated at Bern University Hospital, Switzerland. Results FAST failed to detect free fluid or organ lesions in 45 of 226 patients with spleen or liver injuries (sensitivity 80.1%. Overall specificity was 99.5%. The positive and negative predictive values were 99.4% and 83.3%. The overall likelihood ratios for a positive and negative FAST were 160.2 and 0.2. Grade III-V organ lesions were detected more frequently than grade I and II lesions. Without the additional diagnostic accuracy of a CT scan, the mean ISS of the FAST-false-negative patients would be significantly underestimated and 7 previously unsuspected intra-abdominal injuries would have been missed. Conclusion FAST is an expedient tool for the primary assessment of polytraumatized patients to rule out high grade intra-abdominal injuries. However, the low overall diagnostic sensitivity of FAST may lead to underestimated injury patterns and delayed complications may occur. Hence, in hemodynamically stable patients with abdominal trauma, an early CT scan should be considered and one must be aware of the potential shortcomings of a "negative FAST".

    Full Text Available OBJECTIVES: Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS in the cervical stroma of women with grade III cervical intraepithelial neoplasia (CIN III or in the intratumoral and peritumoral tissue of women with stage I invasive carcinoma. METHODS: Cervical tissue specimens were obtained from 60 women (20 each from control tissues, CIN III and invasive carcinomas. The average ages in the control, CIN III and invasive groups were 43.9 (± 4.3, 35.5 (± 9.5, and 50 (± 11.2 years, respectively. The specimens were immunohistochemically labeled with antibodies to identify T lymphocytes (CD3, cytotoxic lymphocytes (CD8, B lymphocytes (CD20, macrophages (CD68 and iNOS. We evaluated the markers in the stroma above the squamocolumnar junction (control, at the intraepithelial lesion (CIN cases, and in the nfiltrating tumor. Two independent observers performed the immunohistochemical analysis. RESULTS: T lymphocytes, B lymphocytes, macrophages and iNOS were present more frequently (P<0.05 in the stroma of peritumoral invasive tumors compared to the controls and intratumoral invasive cancer samples. CD3+ and CD20+ lymphocytes were present more frequently in CIN III patients compared to samples from patients with intratumoral invasive cancer (P<0.05. CONCLUSION: High numbers of T and B lymphocytes, macrophages and iNOS-expressing cells in the peritumoral stroma of the invasive tumors were observed. Cell migration appeared to be proportional to the progression of the lesion.

    To identify the frequency of psychological and emotional abuse, gender discrimination, verbal sexual harassment, physical sexual harassment, physical assault, and homophobia experienced by general internists. Cross-sectional survey. Canadian general internal medicine practices. The overall response rate was 70.6% (984/1,393); the 501 respondents who classified themselves as general internists were studied. Three-fourths of the internists experienced psychological and emotional abuse at the hands of patients, and 38% of the women and 26% of the men experienced physical assault by patients. The majority of the female internists experienced gender discrimination by patients (67%) and by physician peers (56%). Forty-five percent of the women experienced verbal sexual harassment by patients, and 22% experienced physical sexual harassment by patients. The male internists experienced verbal sexual harassment from nurses slightly more often than the female internists did (19% vs 13%, p > 0.05). Verbal sexual harassment by male colleagues was reported by 35% of the female internists, and physical sexual harassment was reported by 11%. Approximately 40% of general internists reported homophobic remarks by both health care team members and patients. Abuse, discrimination, and homophobia are prevalent in the internal medicine workplace. A direct, progressive, multidisciplinary approach is necessary to label and address these problems.

    As the efficacy of all pediatric high-grade glioma (HGG) treatments is similar and still disappointing, it is essential to also investigate the toxicity of available treatments. Prospectively recorded hematologic and nonhematologic toxicities of children treated with radiochemotherapy in the HIT GBM-C/D and HIT-HGG-2007 trials were compared. Children aged 3-18 years with histologically proven HGG (WHO grade III and IV tumors) or unequivocal radiologic diagnosis of diffuse intrinsic pontine glioma (DIPG) were included in these trials. The HIT-HGG-2007 protocol comprised concomitant radiochemotherapy with temozolomide, while cisplatinum/etoposide (PE) and PE plus ifosfamide (PEI) in combination with weekly vincristine injections were applied during radiochemotherapy in the HIT GBM-C/D protocol. Regular blood counts and information about cellular nadirs were available from 304 patients (leukocytes) and 306 patients (thrombocytes), respectively. Grade 3-4 leukopenia was much more frequent in the HIT GBM-C/D cohort (n = 88, 52%) vs. HIT-HGG-2007 (n = 13, 10%; P <0.001). Grade 3-4 thrombopenia was also more likely in the HIT GBM-C/D cohort (n = 21, 12% vs. n = 3,2%; P <0.001). Grade 3-4 leukopenia appeared more often in children aged 3-7 years (n = 38/85, 45%) than in children aged 8-12 years (n = 39/120, 33%) and 13-18 years (24/100, 24%; P =0.034). In addition, sickness was more frequent in the HIT GBM-C/D cohort (grade 1-2: 44%, grade 3-4: 6% vs. grade 1-2: 28%, grade 3-4: 1%; P <0.001). Radiochemotherapy involving cisplatinum-based polychemotherapy is more toxic than radiotherapy in combination with temozolomide. Without evidence of differences in therapeutic efficacy, the treatment with lower toxicity, i. e., radiotherapy with temozolomide should be used.

    Full text:Background: Tumour hypoxia is associated with disease progression and resistance to therapy. High grade cerebral gliomas have a poor outcome despite advancements in chemotherapy and radiotherapy. 18F-fluoromisonidazole (18F-FMISO) concentrates in hypoxic cells and is associated with tumour grade in gliomas. The aim of this study was to compare the patterns of uptake of 18F-FDG PET and 18F-FMISO PET post-surgery with MRI and areas of recurrence post-radiotherapy. Methods: Patients with high grade cerebral glioma were recruited into this prospective study. All patients had post-surgical, pre-radiotherapy 18F-FDG, 18F-FMISO and MRI scans, which were all repeated 4-6 weeks post-completion to radiotherapy. The patients were followed-up clinically three monthly and re-imaged if indicated. Results: Ten patients were enrolled in this study, mean age 62 years (range 55-69 years), who all had pre-radiotherapy scans performed. Seven patients had scans done pre- and post-radiotherapy, with 3 patients with only pre-therapy scans. Nine patients had significant FMISO uptake and 8 patients demonstrated abnormal FDG uptake. The areas of FMISO uptake on pre-radiotherapy scans correlated with the most abnormal areas of contrast-enhancement on pre-treatment MRI and areas of locally recurrent disease on post-treatment MRI in eight patients. Nine patients had locally recurrent disease on follow-up MRI. FMISO was more predictive of tumour recurrence compared to FDG. Conclusion: Post-surgical 18F-FMISO PET in patients with cerebral glioma is more predictive of areas of recurrent disease compared to 18F-FDG PET.

    Stigma is commonly experienced by people living with HIV/AIDS and by those providing care to HIV/AIDS patients. Few intervention studies have explored the impact of workplace policies and/or quality improvement on stigma. We examine the contribution of health care workplace policies, procedures and quality assurance initiatives, and self- and peer-assessed individual nurse practices, to nurse-reported HIV/AIDS-stigma practices toward patients living with HIV/AIDS and nurses in health care settings. Our sample of survey respondents (n = 1157) included managers (n = 392) and registered/enrolled nurses (n = 765) from 29 facilities in 4 countries (South Africa, Uganda, Jamaica, Kenya). This is one of the first studies in LMIC countries to use hierarchical linear modeling to examine the contributions of organizational and individual factors to HIV/AIDS stigma. Based on our results, we argue that organizational interventions explicitly targeting HIV/AIDS stigma are required to reduce the incidence, prevalence and morbidity of HIV/AIDS.

    Purpose: The present study investigates relationship between dose–volume parameters and severe bowel toxicity after postoperative radiation treatment (PORT) for cervical cancer. Methods and Materials: From June 2010 to December 2012, a total of 71 patients undergoing PORT were included. Small bowel (SB) and large bowel (LB) loops were contoured 2 cm above the target volume. The volume of SB and LB that received 15 Gy, 30 Gy, and 40 Gy was calculated (V15 SB, V15 LB, V30 SB, V30 LB, V40 SB, V 40 LB). On follow-up, bowel toxicity was scored using Common Terminology Criteria for Adverse Events (CTCAE), version 3.0. A reciever operating characteristic (ROC) curve identified volume thresholds that predicted for grade 3 or higher toxicity with highest specificity. All data was dichotomized across these identified cut-off values. Univariate and multivariate analysis was performed using SPSS, version 15. Results: The median patient age was 47 years (range, 35-65 years). Of the 71 patients, 46 received image-guided intensity modulated radiation therapy, and 25 received conformal radiation (50 Gy in 25 fractions for 5 weeks). Overall, 63 of 71 patients received concurrent chemotherapy. On a median follow-up of 18 months (range, 8-29 months), grade 2 or higher bowel toxicity was seen in 22 of 71 patients (30.9%) and grade 3 or higher bowel toxicity was seen in 9 patients (12.6%). On univariate analysis, V15 SB <275 cc (P=.01), V30 SB <190 cc (P=.02), V40 SB <150 cc (P=.01), and V15 LB <250 cc (P=.03), and V40 LB <90 cc (P=.04) predicted for absence of grade 3 or higher toxicity. No other patient- or treatment-related factors were statistically significant. On multivariate analysis, only V15 SB (P=.002) and V15 LB (P=.03) were statistically significant. Conclusions: V 15 Gy SB and LB are independent predictors of late grade 3 or higher toxicity. Restricting V15 SB and V15 LB to <275 cc and <250 cc can reduce grade 3 or higher toxicity to less than 5%.

    Full Text Available ABSTRACT The current study aimed to identify and analyze the prevalence of ethical conflicts experienced by medical students. This study is a cross-sectional and analytical research that was conducted in a public school in the state of Minas Gerais, Brazil. The instrument used for the data collection was a self-administered questionnaire. The data collected were presented in absolute and percentage values. For the analytical statistical treatment of the data, the level of significance was considered p <0.05. The outcome variables were: Experiences of ethical conflicts in interpersonal relations within the medical course and Ethical conduct in health care. The identification of the prevalence of ethical conflicts in the undergraduate program adopted the perspective of different interpersonal relations (academic-teaching, academic-academic, academic-employee, academic-patient, teacher-teacher, teacher-patient, teacher-employee and employee-patient.

    Treatment response assessment in high-grade gliomas uses contrast enhanced T1-weighted MRI, but is unreliable. Novel advanced MRI techniques have been studied, but the accuracy is not well known. Therefore, we performed a systematic meta-analysis to assess the diagnostic accuracy of anatomical and advanced MRI for treatment response in high-grade gliomas. Databases were searched systematically. Study selection and data extraction were done by two authors independently. Meta-analysis was performed using a bivariate random effects model when ≥5 studies were included. Anatomical MRI (five studies, 166 patients) showed a pooled sensitivity and specificity of 68% (95%CI 51-81) and 77% (45-93), respectively. Pooled apparent diffusion coefficients (seven studies, 204 patients) demonstrated a sensitivity of 71% (60-80) and specificity of 87% (77-93). DSC-perfusion (18 studies, 708 patients) sensitivity was 87% (82-91) with a specificity of 86% (77-91). DCE-perfusion (five studies, 207 patients) sensitivity was 92% (73-98) and specificity was 85% (76-92). The sensitivity of spectroscopy (nine studies, 203 patients) was 91% (79-97) and specificity was 95% (65-99). Advanced techniques showed higher diagnostic accuracy than anatomical MRI, the highest for spectroscopy, supporting the use in treatment response assessment in high-grade gliomas. (orig.)

    Gynecomastia (GM) is a benign condition with glandular tissue enlargement of the male breast. GM is classified into 4 grades of increasing severity. We describe a series of GM grade I-II, diagnosed, treated surgically and analyzed regarding feasibility, complication rate, and satisfaction. From 2005 to 2012, a chart review was performed for 53 patients. Preoperative examination included endocrine and urological examination and exclusion of other pathological conditions. The surgical technique consisted of liposuction through an inframammarian-fold incision and excision of the glandular tissue by a minimal periareolar approach. A total number of 53 male patients with 104 breasts were available for analysis. By liposuction, a median of 300 ml (range: 10-1000 ml) was aspirated from each breast and 25.1 g (range: 3-233 g) gland tissue was resected. Surgery lasted between 25 and 164 min per patient (median: 72 min). 2 postoperative hemorrhages occurred (n = 2, 3.8%). 2 patients underwent re-operation due to cosmetic reasons (n = 2, 3.8%). This analysis demonstrates that treatment of GM grade I-II can easily be performed by liposuction combined with subcutaneous resection of the glandular tissue as a minimally invasive and low-impact surgical treatment with a low rate of complications and excellent patient satisfaction. Preoperative workup is important to rule out specific diseases or malignancy causing the GM.

    Among patients with chronic kidney disease (CKD) in the United States, HCV infection causes significant morbidity and mortality and results in substantial healthcare costs. A once-daily oral regimen of elbasvir/grazoprevir (EBR/GZR) for 12 weeks was found to be a safe and efficacious treatment for HCV in patients with CKD. We evaluated the cost-effectiveness of EBR/GZR in treatment-naïve and treatment-experienced CKD patients compared with no treatment (NoTx) and pegylated interferon plus ribavirin (peg-IFN/RBV) using a computer-based model of the natural history of chronic HCV genotype 1 infection, CKD and liver disease. Data on baseline characteristics of the simulated patients were obtained from NHANES, 2000-2010. Model inputs were estimated from published studies. Cost of treatment with EBR/GZR and peg-INF/RBV were based on wholesale acquisition cost. All costs were from a third-party payer perspective and were expressed in 2015 U.S. dollars. We estimated lifetime incidence of liver-related complications, liver transplantation, kidney transplantation, end-stage live disease mortality and end-stage renal disease mortality; lifetime quality-adjusted life years (QALY); and incremental cost-utility ratios (ICUR). The model predicted that EBR/GZR will significantly reduce the incidence of liver-related complications and prolong life in patients with chronic HCV genotype 1 infection and CKD compared with NoTx or use of peg-IFN/RBV. EBR/GZR-based regimens resulted in higher average remaining QALYs and higher costs (11.5716, $191 242) compared with NoTx (8.9199, $156 236) or peg-INF/RBV (10.2857, $186 701). Peg-IFN/RBV is not cost-effective, and the ICUR of EBR/GZR compared with NoTx was $13 200/QALY. Treatment of a patient on haemodialysis with EBR/GZR resulted in a higher ICUR ($217 000/QALY). Assuming a threshold of $100 000 per QALY gained for cost-effectiveness, use of elbasvir/grazoprevir to treat an average patient with CKD can be considered cost

    Symptom clusters must be identified in patients with high-grade brain cancers for effective symptom management during cancer-related therapy. The aims of this study were to identify symptom clusters in patients with high-grade brain cancers and to determine the relationship of each cluster with the performance status and quality of life (QOL) during concurrent chemoradiotherapy (CCRT). Symptoms were assessed using the Memorial Symptom Assessment Scale, and the performance status was evaluated using the Karnofsky Performance Scale. Quality of life was assessed using the Functional Assessment of Cancer Therapy-General. This prospective longitudinal survey was conducted before CCRT and at 2 to 3 weeks and 4 to 6 weeks after the initiation of CCRT. A total of 51 patients with newly diagnosed primary malignant brain cancer were included. Six symptom clusters were identified, and 2 symptom clusters were present at each time point (ie, "negative emotion" and "neurocognitive" clusters before CCRT, "negative emotion and decreased vitality" and "gastrointestinal and decreased sensory" clusters at 2-3 weeks, and "body image and decreased vitality" and "gastrointestinal" clusters at 4-6 weeks). The symptom clusters at each time point demonstrated a significant relationship with the performance status or QOL. Differences were observed in symptom clusters in patients with high-grade brain cancers during CCRT. In addition, the symptom clusters were correlated with the performance status and QOL of patients, and these effects could change during CCRT. The results of this study will provide suggestions for interventions to treat or prevent symptom clusters in patients with high-grade brain cancer during CCRT.

    Temozolomide (TMZ) and BCNU have demonstrated anti-glioma synergism in preclinical models. We report final data from a prospective, multi-institutional study of BCNU wafers and early TMZ followed by radiation therapy with TMZ in patients with newly diagnosed malignant glioma. 65 patients were consented in 4 institutions, and 46 patients (43 GBM, 3 AA) were eligible for analysis. After resection and BCNU wafer placement, TMZ began on day four postoperatively. Radiation and TMZ (RT/TMZ) were then administered, followed by monthly TMZ at 200 mg/m2 for the first 26 patients, which was reduced to 150 mg/m2 for the remaining 20 patients. Non-hematologic toxicities were minimal. Nine of 27 patients (33 %) who received 200 mg/m2 TMZ, but only 1 of 20 (5 %) who received 150 mg/m2, experienced grade 3/4 thrombocytopenia. Median progression free survival (PFS) and overall survival (OS) period was 8.5 and 18 months, respectively. The 1-year OS rate was 76 %, which is a significant improvement compared with the historical control 1-year OS rate of 59 % (p = 0.023). However, there was no difference in 1-year OS compared with standard RT/TMZ (p = 0.12) or BCNU wafer followed by RT/TMZ (p = 0.87) in post hoc analyses. Early post-operative TMZ can be safely administered with BCNU wafers following resection of malignant glioma at the 150 mg/m2 dose level. Although there was an OS benefit compared to historical control, there was no indication of benefit for BCNU wafers and early TMZ in addition to standard RT/TMZ or early TMZ in addition to regimens of BCNU wafers followed by RT/TMZ.

    Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement. If the emergence of especial skills depends on large-scale movement, one would expect archery to escape so-called especialism. But if the emergence of especial skills reflects a more general tendency for highly specific learning, experienced archers should show especial skills. The authors obtained evidence consistent with the latter prediction. The expert archers did much better at their most highly practiced distance than would be expected by looking at the overall function relating shooting score to distance. We offer a mathematical model to account for this result. The findings attest to the generality of the especial skills phenomenon.

    To know the ethical problems experienced by oncology nurses. Descriptive and exploratory study with a qualitative approach, performed in inpatient units and in chemotherapy out-patients units that provide assistance to oncological patients in two capitals in the South region of Brazil. Eighteen nurses participated in this study, selected by snowball sampling type. For data collection, semi-structured interviews were carried out, which were recorded and transcribed, and then analyzed by thematic analysis. Two categories were established: when informing or not becomes a dilemma - showing the main difficulties related to oncological treatment information regarding health staff, health system, and infrastructure; to invest or not - dilemmas related to finitude - showing situations of dilemmas related to pain and confrontation with finitude. For the effective confrontation of the ethical problems experienced by oncology nurses to occur, it is important to invest in the training of these professionals, preparing them in an ethical and human way to act as lawyers of the patient with cancer, in a context of dilemmas related mainly to the possibility of finitude.

    The aim of this study was to determine whether graded activity restored occupational function in industrial blue-collar workers who were sick-listed for 8 weeks because of subacute, nonspecific, mechanical low back pain (LBP). Patients with LBP, who had been examined by an orthopedic surgeon and a social worker, were randomly assigned to either an activity group (n = 51) or a control group (n = 52). Patients with defined orthopedic, medical, or psychiatric diagnoses were excluded before randomization. The graded activity program consisted of four parts: (1) measurements of functional capacity; (2) a work-place visit; (3) back school education; and (4) an individual, submaximal, gradually increased exercise program, with an operant-conditioning behavioral approach, based on the results of the tests and the demands of the patient's work. Records of the amount of sick leave taken over a 3-year period (ie, the 1-year periods before, during, and after intervention) were obtained from each patient's Social Insurance Office. The patients in the activity group returned to work significantly earlier than did the patients in the control group. The median number of physical therapist appointments before return to work was 5, and the average number of appointments was 10.7 (SD = 12.3). The average duration of sick leave attributable to LBP during the second follow-up year was 12.1 weeks (SD = 18.4) in the activity group and 19.6 weeks (SD = 20.7) in the control group. Four patients in the control group and 1 patient in the activity group received permanent disability pensions. The graded activity program made the patients occupationally functional again, as measured by return to work and significantly reduced long-term sick leave.

    The comparative studies on grading in subarachnoid hemorrhage (SAH) had several limitations such as the unclear grading of Glasgow Coma Scale 15 with neurological deficits in World Federation of Neurosurgical Societies (WFNS), and the inclusion of systemic disease in Hunt and Hess (H&H) scales. Their differential incremental impacts and optimum cut-off values for unfavourable outcome are unsettled. This is a prospective comparison of prognostic impacts of grading schemes to address these issues. SAH patients were assessed using WFNS, H&H (including systemic disease), modified H&H (sans systemic disease) and followed up with Glasgow Outcome Score (GOS) at 3 months. Their performance characteristics were analysed as incremental ordinal variables and different grading scale dichotomies using rank-order correlation, sensitivity, specificity, positive predictive value, negative predictive value, Youden's J and multivariate analyses. A total of 1016 patients were studied. As univariate incremental variable, H&H sans systemic disease had the best negative rank-order correlation coefficient (-0.453) with respect to lower GOS (p H&H sans systemic disease had the greatest adjusted incremental impact of 0.72 (95% confidence interval (CI) 0.54-0.91) against a lower GOS as compared to 0.6 (95% CI 0.45-0.74) and 0.55 (95% CI 0.42-0.68) for H&H and WFNS grades, respectively. In multivariate categorical analysis, H&H grades 4-5 sans systemic disease had the greatest impact on unfavourable GOS with an adjusted odds ratio of 6.06 (95% CI 3.94-9.32). To conclude, H&H grading sans systemic disease had the greatest impact on unfavourable GOS. Though systemic disease is an important prognostic factor, it should be considered distinctly from grading. Appropriate cut-off values suggesting unfavourable outcome for H&H and WFNS were 4-5 and 3-5, respectively, indicating the importance of neurological deficits in addition to level of consciousness.

    Background: The purpose of our investigation was to compare quantitative T2 relaxation time measurement evaluation of lumbar intervertebral discs with morphological grading in young to middle-aged patients with low back pain, using a standardized region-of-interest evaluation approach. Patients and methods: Three hundred thirty lumbar discs from 66 patients (mean age, 39 years) with low back pain were examined on a 3.0 T MR unit. Sagittal T1-FSE, sagittal, coronal, and axial T2-weighted FSE for morphological MRI, as well as a multi-echo spin-echo sequence for T2 mapping, were performed. Morphologically, all discs were classified according to Pfirrmann et al. Equally sized rectangular regions of interest (ROIs) for the annulus fibrosus were selected anteriorly and posteriorly in the outermost 20% of the disc. The space between was defined as the nucleus pulposus. To assess the reproducibility of this evaluation, inter- and intraobserver statistics were performed. Results: The Pfirrmann scoring of 330 discs showed the following results: grade I: six discs (1.8%); grade II: 189 (57.3%); grade III: 96 (29.1%); grade IV: 38 (11.5%); and grade V: one (0.3%). The mean T2 values (in milliseconds) for the anterior and the posterior annulus, and the nucleus pulposus for the respective Pfirrmann groups were: I: 57/30/239; II: 44/67/129; III: 42/51/82; and IV: 42/44/56. The nucleus pulposus T2 values showed a stepwise decrease from Pfirrmann grade I to IV. The posterior annulus showed the highest T2 values in Pfirrmann group II, while the anterior annulus showed relatively constant T2 values in all Pfirrmann groups. The inter- and intraobserver analysis yielded intraclass correlation coefficients (ICC) for average measures in a range from 0.82 (anterior annulus) to 0.99 (nucleus). Conclusions: Our standardized method of region-specific quantitative T2 relaxation time evaluation seems to be able to characterize different degrees of disc degeneration quantitatively. The

    Low-grade glioma (LGG) is a very common brain tumor in pediatric patients typically associated with a very good prognosis. This prognosis makes it imperative that the risk of long-term treatment-related side effects be kept at an absolute minimum. Proton therapy (PRT) provides a radiation technique that has the potential to further reduce the genesis of radiogenic impairment. We retrospectively assessed 74 patients with LGG who underwent PRT. Conventional three-dimensional photon and PRT plans were generated after contouring structures of neurogenesis, crucial neuronal structures, and areas susceptible to secondary malignancies. Target volume coverage was evaluated using the homogeneity index (HI) and inhomogeneity coefficient (IC). Results were compared using the Wilcoxon-signed rank test, with p < 0.05 being statistically significant. Target volume coverage was comparable for the photon and proton plans. Overall, we could show an essential reduction in maximal, mean, and integral doses in critical neurologic structures, areas of neurogenesis, and structures of neurocognitive function. The study indicated specifically how contralaterally located structures could be spared with PRT. PRT is a highly conformal radiation technique offering superior dosimetric advantages over conventional radiotherapy by allowing significant dose reduction for organs at risk (OAR) that are essential for neurologic function, neurocognition, and quality of life, thus demonstrating the potential of this technique for minimizing long-term sequelae.

    Security is experienced differently in different contexts. This paper argues that in everyday situations, users base their security decisions on a mix of prior experiences. When approaching security and interaction design from an experience approach, tools that help bring out such relevant...... experiences for design are needed. This paper reports on how Prompted exploration workshops and Acting out security were developed to target such experiences when iteratively designing a mobile digital signature solution in a participatory design process. We discuss how these tools helped the design process...... and illustrate how the tangibility of such tools matters. We further demonstrate how the approach grants access to non-trivial insights into people's security experience. We point out how the specific context is essential for exploring the space between experience and expectations, and we illustrate how people...

    Attention to internal body sensations is practiced in most meditation traditions. Many traditions state that this practice results in increased awareness of internal body sensations, but scientific studies evaluating this claim are lacking. We predicted that experienced meditators would display performance superior to that of nonmeditators on heartbeat detection, a standard noninvasive measure of resting interoceptive awareness. We compared two groups of meditators (Tibetan Buddhist and Kundalini) to an age- and body mass index-matched group of nonmeditators. Contrary to our prediction, we found no evidence that meditators were superior to nonmeditators in the heartbeat detection task, across several sessions and respiratory modulation conditions. Compared to nonmeditators, however, meditators consistently rated their interoceptive performance as superior and the difficulty of the task as easier. These results provide evidence against the notion that practicing attention to internal body sensations, a core feature of meditation, enhances the ability to sense the heartbeat at rest.

    In order to describe accurately and comprehend quickly the perfect GIS requirements, this article will integrate the ideas of QFD (Quality Function Deployment) and UML (Unified Modeling Language), and analyze the deficiency of prototype development model, and will propose the idea of the Customer-Experienced Rapid Prototyping (CE-RP) and describe in detail the process and framework of the CE-RP, from the angle of the characteristics of Modern-GIS. The CE-RP is mainly composed of Customer Tool-Sets (CTS), Developer Tool-Sets (DTS) and Barrier-Free Semantic Interpreter (BF-SI) and performed by two roles of customer and developer. The main purpose of the CE-RP is to produce the unified and authorized requirements data models between customer and software developer.

    Purpose/Objective: Although many advances have been made in the use of therapeutic irradiation to treat patients with brain tumors, the neurocognitive effects of conformal radiation therapy (CRT) are poorly known and controversial. Retrospective studies of radiotherapy in children and adults have revealed both leukoencephalopathy and cognitive impairments in follow-up of months to 20 years after treatment. Most prospective studies have examined neurocognitive effects at one year post CRT, and our previous findings (1993,1995) suggest that this endpoint misses the first two phases of the delayed effects of CRT. We also propose that the effects of CRT can be characterized in terms of dissociated curvilinear slopes of neurocognitive impairments, which allow specific hypotheses about the multiple phases of the delayed effects. Materials/Methods: We have examined our neurocognitive model of radiotherapy effects in our current group of 20 patients who have supratentorial, low grade, primary brain tumors. Total CRT doses ranged between 46 to 63 Gy (med. dose of 54 Gy, with fractionations of 1.8-2.0 Gy). Healthy control subjects were matched to patients with respect to age and education. Patients were tested with a comprehensive neuropsychological battery at baseline (6 weeks post resection/biopsy, immediately prior to CRT), at three month intervals for one year, and yearly; current analyses reflect three years post baseline. To test the hypothesis that long-term memory is generally impaired versus selective impairment of verbal/semantic memory processes, we used parallel tests of verbal/semantic and visual/perceptual long-term memory which require association to encode and retrieve the stimuli. The visual long-term memory test was available on 10 patients. Results: A specific treatment-dependent deficit in long-term memory retrieval of word lists was found in 18 of 20 patients at six weeks post completion of CRT, though it was a temporary impairment which rebounded by one

    A phase I, dose-finding study of vorinostat in combination with temozolomide (TMZ) was conducted to determine the maximum tolerated dose (MTD), safety, and pharmacokinetics in patients with high-grade glioma (HGG). This phase I, dose-finding, investigational study was conducted in two parts. Part 1 was a dose-escalation study of vorinostat in combination with TMZ 150 mg/m(2)/day for 5 days every 28 days. Part 2 was a dose-escalation study of vorinostat in combination with TMZ 150 mg/m(2)/day for 5 days of the first cycle and 200 mg/m(2)/day for 5 days of the subsequent 28-day cycles. In part 1, the MTD of vorinostat administered on days 1 to 7 and 15 to 21 of every 28-day cycle, in combination with TMZ, was 500 mg daily. Dose-limiting toxicities (DLT) included grade 3 anorexia, grade 3 ALT, and grade 5 hemorrhage in the setting of grade 4 thrombocytopenia. In part 2, the MTD of vorinostat on days 1 to 7 and 15 to 21 of every 28-day cycle, combined with TMZ, was 400 mg daily. No DLTs were encountered, but vorinostat dosing could not be escalated further due to thrombocytopenia. The most common serious adverse events were fatigue, lymphopenia, thrombocytopenia, and thromboembolic events. There were no apparent pharmacokinetic interactions between vorinostat and TMZ. Vorinostat treatment resulted in hyperacetylation of histones H3 and H4 in peripheral mononuclear cells. Vorinostat in combination with temozolomide is well tolerated in patients with HGG. A phase I/II trial of vorinostat with radiotherapy and concomitant TMZ in newly diagnosed glioblastoma is underway. ©2012 AACR.

    increase was seen (CD4+CD25med pre-flare/flare p = 0.0461; CD4+CD25high baseline/flare p = 0.0269 and pre-flare/flare p = 0.0032. In contrast, no changes in the expression of Foxp3 cells were detected within the subsets of CD4+CD25high regulatory T cells. Of note, no alterations were detected in the suppressive capability of CD4+CD25high regulatory T cells isolated from the peripheral blood of healthy donors, from patients in remission, or from patients with clinical flare. CONCLUSIONS: In patients with UC experiencing acute flare, the CD4+ T compartment demonstrates a distinctly different pattern during treatment with myrrh, chamomile extract, and coffee charcoal than during treatment with mesalazine. These findings suggest an active repopulation of regulatory T cells during active disease. TRIAL REGISTRATION: EU Clinical Trials Register 2007-007928-18/DE.

    Low back pain (LBP) is a major health and economic problem worldwide. Graded activity and physiotherapy are commonly used interventions for nonspecific low back pain. However, there is currently little evidence to support the use of one intervention over the other in the medium-term. To compare the effectiveness of graded activity exercises to physiotherapy-based exercises at mid-term (three and six months' post intervention) in patients with chronic nonspecific LBP. Sixty-six patients were randomly allocated to two groups: graded activity group (n=33) and physiotherapy group (n=33). These patients received individual sessions twice a week for six weeks. Follow-up measurements were taken at three and six months. The main outcome measurements were intensity pain (Pain Numerical Rating Scale) and disability (Rolland Morris Disability Questionnaire). No significant differences between groups after three and six month-follow ups were observed. Both groups showed similar outcomes for pain intensity at three months [between group differences: -0.1 (95% confidence interval [CI]=-1.5 to 1.2)] and six months [0.1 (95% CI=-1.1 to 1.5)], disability at three months was [-0.6 (95% CI=-3.4 to 2.2)] and six months [0.0 (95% CI=-2.9 to 3.0)]. The results of this study suggest that graded activity and physiotherapy have similar effects in the medium-term for patients with chronic nonspecific low back pain.

    To assess efficacy of our single-centre experience with inhalative steroids (IS) in lung cancer patients with symptomatic radiation pneumonitis (RP) grade II. Between 05/09 and 07/10, 24 patients (female, n = 8; male, n = 16) with lung cancer (non-small cell lung carcinoma [NSCLC]: n = 19; small cell lung cancer [SCLC]: n = 3; unknown histology: n = 2) and good performance status (ECOG ≤1) received definitive radiotherapy to the primary tumour site and involved lymph nodes with concurrent chemotherapy (n = 18), sequential chemotherapy (n = 2) or radiation only (n = 4) and developed symptomatic RP grade II during follow-up. No patient presented with oxygen requiring RP grade III. The mean age at diagnosis was 66 years (range: 50–82 years). Nine patients suffered from chronic obstructive pulmonary disease (COPD) before treatment, and 18 patients had a smoking history (median pack years: 48). The mean lung dose was 15.5 Gy (range: 3.0–23.1 Gy). All patients were treated with IS. If a patient’s clinical symptoms did not significantly improve within two weeks of IS therapy initiation, their treatment was switched to oral prednisolone. All 24 patients were initially treated with a high dose IS (budesonide 800 μg 1-0-1) for 14 days. Of the patients, 18 showed a significant improvement of clinical symptoms and 6 patients did not show significant improvement of clinical symptoms and were classified as non-responders to IS. Their treatment was switched to oral steroids after two weeks (starting with oral prednisolone, 0.5 mg/kg bodyweight; at least 50 mg per day). All of these patients responded to the prednisolone. None of non-responders presented with increased symptoms of RP and required oxygen and / or hospitalization (RP grade III). The median follow-up after IS treatment initiation was 18 months (range: 4–66 months). The median duration of IS treatment and prednisolone treatment was 8.2 months (range: 3.0–48.3 months) and 11.4 months (range: 5.0–44

    The intention of this research was to define the predictive factors for acute esophagitis (AE) in lung cancer patients treated with concurrent chemotherapy and three-dimensional conformal radiotherapy. The data for 72 lung cancer patients treated with concurrent chemoradiotherapy between 2008 and 2010 were prospectively evaluated. Mean lung dose, mean dose of esophagus, volume of esophagus irradiated and percentage of esophagus volume treated were analysed according to esophagitis grades. The mean esophageal dose was associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P<0.001). However, the mean lung dose and the volume of esophagus irradiated were not associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P=0.50 and P=0.41, respectively). The mean radiation d
